As shown in fig. 1(a), the automatic sorting mechanism according to an embodiment of the present invention includes a toggle mechanism 910, a main channel 901, two or more sub-channels 902, and sorting storage devices 903 in the same number as the sub-channels.
The main channel 901 is respectively communicated with each secondary channel 902 and forms a corresponding branch 901-1 at the joint, each secondary channel 902 corresponds to one sorting storage device 903, the toggle mechanism 910 can toggle the workpiece 930 so as to enable the workpiece 930 to advance to each branch 901-1 along the main channel 901, and enable the workpiece 930 to reach the corresponding secondary channel 902 through any branch 901-1 and then reach the corresponding sorting storage device 903 through the secondary channel 902.
In order to save space and cost, in one embodiment, the sub-channel 902 and the corresponding sorting storage 903 may be combined into one part or one of them may be omitted, and such modifications or changes are still within the scope of the present invention.
In order to save space and cost, in one embodiment, several of the sorting storage devices 903 or all of the sorting storage devices 903 may be combined into one part, and space division may be implemented by means of grooves, spacers, or sufficient spacing gaps, and these modifications or changes still fall within the protection scope of the present invention.
In one embodiment, the secondary channel 902 is an inclined open slot with an adjustable slot width. In another embodiment, the secondary channel 902 is an open chute with a fixed slot width that is larger than the maximum width of the workpiece 930, thereby simplifying the structure and eliminating the slot width adjustment mechanism of the secondary channel 902. The maximum width of the workpiece 930 is the maximum width of the workpiece with the largest width among the workpieces 930 of respective sizes expected to be applicable when the sorting mechanism is designed.
In one embodiment, the secondary channels 902 are respectively located at two sides of the primary channel 901, for example, the secondary channels 902 are alternately distributed at two sides of the primary channel 901, that is, a first secondary channel 902 is distributed at the left side of the primary channel 901, a second secondary channel 902 is distributed at the right side of the primary channel 901, a third secondary channel 902 is distributed at the left side of the primary channel 901, and so on.
In another embodiment, the secondary channels 902 are all located on one side of the primary channel 901. At the moment, the automatic sorting mechanism is compact in structure, beneficial to saving the number of the movement mechanisms, capable of reducing space interference, convenient to design, install and adjust and convenient for workers to operate.
The communication may be a cross connection as shown in fig. 1(a), or may be a non-cross connection, i.e., a certain distance is kept between the main channel 901 and the sub-channel 902, but the workpiece 930 is considered to be communicated as long as the workpiece 930 can slide from the main channel 901 into the corresponding sorting storage device 903 through the sub-channel 902.
In one embodiment, the automatic sorting mechanism of an embodiment of the present invention further includes a sorting base 920 for fixedly mounting the main components to be fixedly mounted as described above and below. In one embodiment, the automated sorting mechanism is integrally and fixedly mounted to the sorting base 920.
In one embodiment, the toggle mechanism 910 includes a main pushing unit 911 and the same number of ejecting units 913 as the number of the secondary channels 902; the ejection unit 913 includes a pusher 913-2, the pusher 913-2 can hold the workpiece 930 to push the workpiece 930 to move or advance along the main path 901, and when the workpiece 930 reaches the designated branch 901-1, the pusher 913-2 can eject the workpiece 930 from the main path 901 into the sub-path 902 and to the corresponding sorting storage 903 through the sub-path 902; the main pushing unit 911 provides pushing force for the workpiece 930 to sequentially pass through the branch ports 901-1 along the main passage 901.
In one embodiment, the toggle mechanism 910 further comprises a toggle base 914 for fixedly mounting the major components of the toggle mechanism 910. The toggle base 914 is fixedly installed on the sorting base 920.
To further improve the degree of automation and flexibility, and to improve the efficiency of automatic sorting and the quality of the sorted goods, in one embodiment, the toggle mechanism 910 further includes a toggle unit 912. The card-moving unit 912 may drive all the ejecting units 913 to reciprocate in a direction perpendicular to the moving line of the workpiece 930 in the main passage 901.
As shown in fig. 2(a) and 2(b), in one embodiment, when the card-poking unit 912 is away from the main channel 901, the poking heads 913-2 of all the ejection units 913 are away from the workpiece 930, i.e. the poking heads 913-2 no longer seize the workpiece 930, and thus cannot push the workpiece 930 to move along the main channel 901; when the engaging unit 912 approaches or abuts the main channel 901, the engaging heads 913-2 of all the ejecting units 913 move toward the workpiece 930 and engage the workpiece 930 (when there is a corresponding workpiece 930 in the main channel 901 at a corresponding position of the ejecting units 913), so as to push the workpiece 930 to move linearly along the main channel 901.
In one embodiment, as shown in FIG. 1(b), the pusher 913-2 includes a card pushing edge 913-2-1 and a push-out edge 913-2-2, respectively.
The clamping edge 913-2-1 may clamp and abut against one side of the workpiece 930 to push the workpiece 930 to move linearly along the main channel 901 toward the other side of the workpiece 930.
The ejection edge 913-2-2 may abut against one side of the workpiece 930 and push the workpiece 930 to move linearly along the side of the workpiece 930 toward the other side of the workpiece 930 along the sub-channel 902 or slide into the sorting storage device 903 corresponding to the sub-channel 902.
In one embodiment, as shown in fig. 1(b), the side of workpiece 930 that abuts against raised edge 913-2-2 is perpendicular to the side that abuts against card edge 913-2-1, i.e., raised edge 913-2-2 is perpendicular to card edge 913-2-1. At the moment, the system is simple and compact in structure and convenient to design and engineer.
In other embodiments, the ejecting edge 913-2-2 of the shifting block 913-2 and the clamping edge 913-2-1 form an angle different from 90 degrees, which is the same as the angle between the secondary channels of the primary channel.
In one embodiment, the main pushing unit 911, the card dialing unit 912 and each ejecting unit 913 each include a corresponding linear driving mechanism, and each linear driving mechanism corresponds to the main pushing driving mechanism 911-1, the card dialing driving mechanism 912-1 and the ejecting driving mechanism 913-1, respectively.
Each linear driving mechanism can be realized by adopting a hydraulic cylinder or a pneumatic cylinder which outputs linear motion, and can also be realized by adopting a motor and a linear transmission mechanism such as a ball screw, a gear rack, a worm gear, a belt transmission mechanism, a chain transmission mechanism and the like, and can also be directly driven by adopting a linear motor. The motor can be a standard servo motor product with a speed reducer, and can also be a conventional servo motor product without a speed reducer, such as a torque motor and the like. Each linear driving mechanism also relates to a linear guide rail, a driving control device, a position feedback device or an anti-collision device and the like for linear guiding, the specific installation, manufacture and use modes of the linear driving mechanisms refer to the prior art, and the linear driving mechanisms can be specifically selected or combined according to the specific workpiece category and characteristics and are conventional prior art.
In one embodiment, each of the main pushing unit 911, the card dialing unit 912 and each of the ejecting units 913 includes a corresponding guiding component for guiding and supporting the linear movement of the moving portion relative to the fixed portion, and each guiding component corresponds to the main pushing guiding component 911-3, the card dialing guiding component 912-3 and the ejecting guiding component 913-3, respectively.
Each guide assembly can adopt a universal standard product, namely a linear guide rail, namely a combination of a guide rail and a slide block, the installation mode is installed according to a conventional mode, namely the slide block is fixed with the mobile station, the guide rail is fixed with the fixed seat, a structure with two guide rails arranged in parallel is adopted, the guide assemblies are conventional prior art, and the description is omitted.
In one embodiment, because each ejection unit 913 is only acting on a single workpiece, the force is relatively small, and to save cost, the corresponding ejection guide assembly 913-3 can be eliminated, directly using the ejection drive mechanism 913-1 as the guide support structure of the linear cylinder itself.
In one embodiment, the main push unit 911 has a long acting length, needs to bear a large weight, and simultaneously takes space saving into consideration, so that the structure is compact, the main push guide assembly 911-3 adopts a single-groove sliding groove type structure, that is, a linear sliding groove is arranged on the toggle base 914, one or more than one sliding block is fixedly arranged on the main push movable worktable 911-2, and the linear guide function and the support function are realized through the matching of the sliding block and the sliding groove.
In one embodiment, the pusher 913-2 is driven by an ejection driving mechanism 913-1 to reciprocate linearly along the sub-channel 902. When the card dialing unit 912 approaches the main channel 901, the dialing head 913-2 approaches the main channel 901, so as to push the workpiece 930 into the sub-channel 902 and make the workpiece 930 enter the corresponding sorting storage device 903 through the sub-channel 902; when the card pulling unit 912 is away from the main channel 901, the pulling head 913-2 is away from the main channel 901, and the workpiece 930 cannot be pushed into the sub-channel 902 and the corresponding sorting and storing device 903.
In one embodiment, the main push unit 911 includes a corresponding main push mobile station 911-2, and the card dialing unit 912 includes a corresponding card dialing mobile station 912-2.
In specific implementation, the main pushing unit 911 and the card dialing unit 912 form an XY two-axis motion platform together, and the specific implementation manner of the XY two-axis motion platform may refer to the specific implementation manner of the XY two-axis motion platform in the prior art, which is not described herein again.
In one embodiment, as shown in fig. 1(a), 5, 6, and 7, the card dialing unit 912 is an X-axis motion unit, the main pushing unit 911 is a Y-axis motion unit, and the main pushing unit 911 is fixedly mounted on the card dialing movable table 912-2 of the card dialing unit 912. The main pushing moving table 911-2 is fixedly connected to all the ejecting units 913, so that all the ejecting units 913 can synchronously move linearly in the main channel M direction (i.e. forward direction, the same direction) by the main pushing driving mechanism 911-1, that is, the main pushing driving mechanism 911-1 makes the shifting block 913-2 drive the workpiece 930 to sequentially pass through each of the branched ports 901-1 along the main channel 901. The card dialing moving table 912-2 is fixedly connected with the fixed components of the main pushing unit 911, and is also fixedly connected with all the ejecting units 913 in a direction perpendicular to the main channel M, i.e., in the direction of the sub-channel W (i.e., in the sliding direction, the same below), so that all the ejecting units 913 can simultaneously and linearly move along the sub-channel direction W by being driven by the card dialing driving mechanism 912-1, that is, the card dialing driving mechanism 912-1 makes the dialing head 913-2 deviate from or abut against the main channel 901.
Similarly, in another embodiment, as shown in fig. 1(a), the functions of the main push moving table 911-2 and the card push moving table 912-2 remain unchanged, but the card push unit 912 is a Y-axis motion unit, the main push unit 911 is an X-axis motion unit, and the card push unit 912 is fixedly mounted on the main push moving table 911-2 of the main push unit 911.
In one embodiment, to simplify control, design and operation, the individual ejection units 913 are equally spaced, and the individual secondary channels 902 are equally spaced.
As shown in fig. 2, 3, and 4, one cycle of the automatic sorting mechanism of the present embodiment is as follows.
The first step is as follows: as shown in fig. 2(a), all of the pusher heads 913-2 of the card-dialing unit 912 face away from the main channel 901, the distance between the ejection edge 913-2-2 of the pusher head 913-2 and the workpiece 930 is B1, and the main pushing unit 911 is located at the leftmost side;
the second step is that: as shown in fig. 2(B), all of the pusher 913-2 of the card pulling unit 912 simultaneously abut against the main channel 901 and move a distance B1 by the driving of the card pulling driving mechanism 912-1, and the distance between the ejecting edge 913-2-2 of the pusher 913-2 and the workpiece 930 is 0;
the third step: as shown in fig. 2(b) and fig. 3(a), all of the dialing parts 913-2 of the card dialing unit 912 are simultaneously linearly moved by a distance a1 along the main passageway M by the main pushing driving mechanism 911-1;
the fourth step: as shown in fig. 3(b), when no sorting command is issued, the sixth step is entered; when a sorting instruction is sent, the corresponding push-out driving mechanism 913-1 drives the corresponding shifting block 913-2 to move linearly for a distance C1 along the direction of the corresponding sub-channel W, so as to push the workpiece 930 to be pushed out into the sub-channel 902;
the fifth step: as shown in fig. 3(C), the workpiece 930 is moved linearly along the sub-path 902 and slid into the sorting storage 903 corresponding to the sub-path 902, and then the corresponding ram 913-2 is moved linearly in the opposite direction of the sub-path W by the distance C1, and the top edge 913-2-2 of the ram 913-2 is aligned with the top edge 913-2-2 of the other ram 913-2;
and a sixth step: as shown in fig. 4(a), all of the pusher heads 913-2 of the pusher unit 912 are simultaneously moved away from the main channel 901 by a distance B1 by the driving of the pusher driving mechanism 912-1, and the distance between the ejection edge 913-2-2 of the pusher head 913-2 and the workpiece 930 is B1;
the seventh step: as shown in fig. 4(b), all the dialing parts 913-2 of the card dialing unit 912 are simultaneously linearly moved by a distance a1 in the opposite direction of the main channel M by the main push driving mechanism 911-1, and are reset and returned to the first step state.
Through the above-mentioned work cycle, if a sorting command (manually recognized or automatically recognized sorting category) is issued, the corresponding workpiece 930 is ejected into the corresponding sorting storage 903, and if no sorting command is issued, the corresponding workpiece 930 is moved by a distance a1 in the direction of the main lane M. It is clear that each work cycle, for each workpiece 930 not given a sorting command, is moved a distance a1 in the direction of the main path M.
In one embodiment, to ensure that the workpieces 930 are not jammed at the end of the main aisle 901 for cyclic automatic sorting, a storage device is provided at the end of the main aisle 901 and is automatically slid into when the workpieces 930 reach the end.
In one embodiment, it is possible to ensure that all workpieces 930 are ejected to the corresponding sorting storage 903 when they reach the position of the last sub-lane 902 by strictly defining the sorting rules, i.e. the last sorting storage 903 is dedicated to storing the last sorted category.
In the above embodiment, the linear driving distance of the main push driving mechanism 911-1 is short, and when there are five sub-channels 902, only one fifth of the distance is needed to move the workpiece 930 to the position of the last sub-channel 902, i.e., the driving distance for realizing the whole movement in the conventional technology is N times of the moving distance of the main push driving mechanism 911-1 of the present invention, where N is the number of the sub-channels 902.
In one embodiment, to further improve the sorting efficiency, the probability of the sorted items corresponding to each sorting storage device 903 is sequentially decreased along the main channel M. When the sorted articles corresponding to each sorting storage device 903 are set, the probability of each sorted article appearing should be counted through trial operation or experiment.
In one embodiment, to prevent the workpiece 930 from being bumped or damaged when the workpiece 930 is shifted by the shift head 913-2, an elastic buffer device, i.e., a shift head buffer device, is added to the shift head 913-2 to minimize damage to the workpiece 930 and to prevent the workpiece 930 from being bumped from the normal position. In one embodiment, the ejecting edge 913-2-2 and the clamping edge 913-2-1 of the shifting block 913-2 are respectively provided with an elastic buffer block or an elastic buffer strip, and both are made of a plastic with good shock absorption, such as polypropylene, polyethylene, foamed plastic, and the like.
In one embodiment, as shown in fig. 8(a), the main channel 901 is used for accommodating a support groove 901-2 for supporting the workpiece 930 and making the workpiece 930 slide along a straight line, and the support groove 901-2 is a closed quadrilateral, four sides of the cross section of the workpiece 930 are limited, and the main channel 901 carries the workpiece 930 through the quadrilateral support groove 901-2, so as to ensure that the workpiece 930 can slide along the support groove 901-2 in a straight line when the shifting block 913-2 shifts. When the workpiece 930 is to be pushed out to the sub-passage 902 via the branch 901-1, as shown in fig. 8(b), a limit edge should be removed, and the push-out edge 913-2-2 of the pusher 913-2 can push out the workpiece 930 and make the workpiece 930 pass through the position of the removed limit edge, and then be pushed out to the sub-passage 902 via the branch 901-1.
In another embodiment, as shown in fig. 8(c) and 8(d), the supporting groove 901-2 of the main channel 901 is inclined, the main channel 901 only carries the workpiece 930 through the inclined L-shaped chute, i.e. the supporting groove 901-2, so that the workpiece 930 abuts against the inclined supporting surface of the supporting groove 901-2 by gravity and does not topple over by itself to slide into the sub-channel 902, and the workpiece 930 can slide linearly along the inclined supporting groove 901-2 under the stirring of the stirring head 913-2. When the workpiece 930 is required to be pushed out to the sub-passage 902 through the branch 901-1, the push-out edge 913-2-2 of the pusher 913-2 pushes the workpiece 930 obliquely upward, and the workpiece 930 is pushed out to the sub-passage 902 through the branch 901-1. The inclined scheme can reduce the limit edges of the workpiece 930, and reduce the limit edge removing movement and corresponding removing mechanism before the ejection edges 913-2-2 of the shifting heads 913-2 eject the workpiece 930, thereby improving the sorting efficiency, reducing the sorting procedures and steps and facilitating the ejection of the workpiece 930. In one embodiment, as shown in FIG. 9, to prevent the workpiece 930 from jumping up and down during high speed movement, a plurality of upper and lower limiting plates 901-3 are disposed above the L-shaped supporting groove 901-2 to limit three sides of the workpiece 930. In order to adapt to workpieces 930 of different sizes, the upper and lower limiting plates 901-3 are separable from the supporting groove 901-2, the upper and lower limiting plates 901-3 can be adjusted up and down, and when the upper and lower limiting plates 901-3 are adjusted to a position suitable for the workpiece 930, the upper and lower limiting plates 901-3 are fixed by means of screws and the like.
In addition, the shapes of the supporting groove 901-2 and the upper and lower limiting plates 901-3 need to be adjusted according to the shape of the workpiece, and are within the protection range by adopting similar technical means.
In one embodiment, the automated sorting mechanism of one embodiment of the present invention is manually fed sheet by sheet.
In another embodiment, the automatic sorting mechanism according to an embodiment of the present invention further includes a feeding module 940 for replacing or improving the efficiency of manual feeding.
In one embodiment, as shown in fig. 10, the feeding module 940 includes a feeding base 941 and a feeding chute 942. The feeding chute 942 is obliquely disposed on the feeding base 941, and the workpiece 930 can automatically slide into the bottom of the feeding chute 942 along the feeding chute 942 under the action of gravity, so as to achieve automatic feeding.
In one embodiment, as shown in fig. 10 and 11, in order to make the feeding chute 942 suitable for workpieces with various dimensions, the feeding chute 942 is provided with a chute adjusting plate 942-1 and a chute guide rod 942-2, and the chute adjusting plate 942-1 is fixedly connected to the chute guide rod 942-2. The feeding base 941 or the chute fixing portion 942-3 of the feeding chute 942 fixed to the feeding base 941 is provided with a guiding hole to match with the chute guiding rod 942-2, so that the chute adjusting plate 942-1 and the chute guiding rod 942-2 slide linearly left and right under the guiding action of the guiding hole, and the function of adjusting the width of the chute is achieved. After the groove width is adjusted in place, the chute guide rod 942-2 is locked by a locking mechanism such as a screw and the like, so that the chute adjusting plate 942-1 is locked to fix the groove width. When the width of the groove needs to be adjusted, the locking mechanism is released, and the chute adjusting plate 942-1 and the chute guide rod 942-2 are further released.
In practical production, when the workpiece 930 slides down in the loading chute 942 by its own weight, the gravity may be smaller or slightly larger than the friction force, and at this time, the workpiece 930 cannot slide down in the loading chute 942 by its own weight or the sliding speed is too slow.
In one embodiment, to solve the problem of the inability to slide down or the slow speed of sliding down, a loading pusher 943 is disposed in the loading chute 942. One embodiment of the feeding pusher 943 is a weight with smooth surface, the width of which is the same or approximately the same as the width of the workpiece 930, and the weight can slide down in the feeding chute 942 like the workpiece 930 due to its own weight, and the weight can strongly push the workpiece 930 to slide down because the weight is made of a metal material with high density, such as copper, steel, lead, etc., and the surface is smoothly treated by grinding with a grinder or coating with lubricating oil, etc.
In another embodiment, as shown in fig. 10(c), a pusher driving unit 944 is additionally provided, and the feeding pusher 943 is driven by the pusher driving unit 944 to move linearly in the downward sliding direction of the workpiece 930. The push block driving unit 944 can be realized by a linear motor direct driving module based on linear guide rail guiding support, can be specifically realized by a pneumatic cylinder combined with a linear guide rail, and can also be specifically realized by a pneumatic cylinder having linear driving and guiding support functions.
In one embodiment, the pusher driving unit 944 comprises a pusher driving cylinder 944-1, a pusher linear guide 944-2 and a pusher fixing table 944-3, and the pusher driving cylinder is connected to and drives the feeding pusher 943 to slide linearly by using a conventional prior art.
In one embodiment, to save space, the push block driving unit 944 is located in the internal cavity of the feeding base 941, and correspondingly, a plurality of push block through slots 942-4 are disposed in the feeding chute 942, the length direction of the push block through slots 942-4 is parallel to the sliding direction of the workpiece 930, and the feeding push block 943 is provided with push block protrusions 943-1, the number of which is the same as that of the push block through slots 942-4 and which can pass through the push block through slots 942-4 from the internal cavity of the feeding base 941 and then contact the workpiece 930, and the push block protrusions 943-1 can push the workpiece 930 to slide downwards. In another embodiment, a pushing block limiting frame 945 is arranged on the pushing block fixing platform 944-3, and when the pushing block limiting frame 945 contacts the lower limit position, a travel switch or a photoelectric switch is used to warn that the workpiece 930 is completely loaded, and the workpiece 930 needs to be added again. At this time, the push block driving cylinder 944-1 drives the push block fixing table 944-3 and the feeding push block 943 to automatically slide upwards to reach the upper limit position, so that the maximum number of workpieces can be accommodated in the feeding chute 942. Then, the maximum number of workpieces 930 are manually placed into the feeding chute 942, and one-time batch feeding can be completed. In the embodiment, the cylinder 944-1 is driven by one push block, so that the feeding push block 943 is pushed to effectively slide downwards, the problem that the workpieces 930 cannot slide smoothly is solved, the feeding push block 943 is pushed to automatically return from the lower limit position to the upper limit position, a worker can conveniently place the workpieces 930 in the largest number at one time, and the automatic return function is realized.
In one embodiment, the automatic sorting mechanism of an embodiment of the present invention further includes a material distribution module 950 for replacing manual material distribution and improving material distribution efficiency.
As shown in FIG. 12(a), in one embodiment, the dispensing module 950 includes a dispensing base 951 and a dispensing tap 952. The material distributing shifting block 952 is disposed on the material distributing base 951, and the workpiece 930 located at the bottom or the bottom can be pushed and shifted by the material distributing shifting block 952 to automatically move to the next station, i.e., the automatic material distributing function is realized. The material distributing base 951 is provided with a material distributing channel 951-1. The workpiece 930 is pushed and pulled by the distributing pusher 952, and can slide linearly along the groove body of the distributing channel 951-1. The material distributing channel 951-1 comprises a rightmost workpiece bearing bottom surface and a leftmost workpiece limiting bottom surface. The rightmost workpiece bearing bottom surface coincides with the right bottom surface of the bottommost or bottommost workpiece 930, and the workpiece 930 is always attached to the rightmost workpiece bearing bottom surface and moves linearly along the rightmost workpiece bearing bottom surface. The distance between the leftmost workpiece limiting bottom surface and the rightmost workpiece bearing bottom surface is greater than the thickness of the workpiece 930 in the left-right direction, for example, 1.1 times, 1.05 times, or 1.025 times the thickness of the workpiece 930 in the left-right direction, so as to prevent the workpiece 930 from falling to the left. The bottom surface of the leftmost side of the distributing shifting head 952 protrudes to form a step relative to the bottom surface of the rightmost workpiece carrier of the distributing channel 951-1, and the thickness of the protruding step is smaller than the thickness of the workpiece 930, and preferably, the thickness of the protruding step is equal to 0.5 to 0.95 times of the thickness of the workpiece 930. The raised steps of the distributing pusher 952 can push the workpiece 930 to slide linearly along the rightmost workpiece-bearing bottom surface of the distributing channel 951-1.
In one embodiment, as shown in fig. 13, the material separating module 950 further includes a material separating driving unit 953 and a material separating guiding unit 954. The material distributing shifting head 952 can reciprocate linearly under the driving of the material distributing driving unit 953 and the guiding support of the material distributing guiding unit 954. The material-dividing driving unit 953 may adopt a conventional prior art cylinder assembly, and the material-dividing guide unit 954 may adopt a conventional prior art linear guide (including two major components of a guide rail and a slider). In one embodiment, the material-dividing driving unit 953 and the material-dividing guide unit 954 may be combined into a single cylinder assembly, and the guide support function of the piston rod of the standardized cylinder assembly may be utilized to omit an additional guide support mechanism.
In one embodiment, as shown in FIG. 12(a), the riving head 952 is a piece of material having a thickness slightly less than the thickness of the workpiece 930. The feed divider 952 is driven by the feed divider driving unit 953 to move linearly along the feed dividing channel 951-1 and to push the lowermost or bottommost workpiece 930 to move to the next station during the linear movement.
As shown in fig. 12(b) and 12(c), at this point, the feed finger 952 begins to push the workpiece 930 to move to the next station.
As shown in fig. 12(d) and 12(e), the dispensing tap 952 now pushes the workpiece 930 about one workpiece 930 length down to the next station.
At this point, as shown in fig. 12(f), the dispensing tap 952 pushes the workpiece 930 to the next station.
In order to improve the material distribution efficiency, the material distribution dial 952 has a high pushing speed, so that the workpiece 930 is also pushed by the material distribution dial 952 at a high speed, and is easily rushed to a non-predetermined position (beyond a certain distance from the predetermined position) due to high-speed inertia, so that the workpiece 930 cannot accurately reach the next station or is damaged due to being blocked by a next station limiting mechanism. In one embodiment, as shown in fig. 14, the material separating module 950 further includes a material separating damper 955. The material separating damper 955 includes one or more plastic wheels, when the workpiece 930 moves to the minimum gap between the plastic wheels and the material separating channel 951-1, the workpiece 930 will be subjected to the friction resistance of the plastic wheels, so as to greatly reduce the moving speed, and since the plastic wheels can rotate, the workpiece 930 can be prevented from being damaged due to the rapid reduction of the speed. To balance the impact problem caused by too much resistance of the plastic wheels with the over-position problem caused by too little resistance, in one embodiment, the material distribution damping device 955 includes two plastic wheels, and through two-stage damping, the impact problem and the over-position problem can be balanced.
In one embodiment, as shown in FIG. 14, to facilitate adjustment of the resistance of the feed damper 955 against the workpiece 930, the feed module 950 further includes a damping resistance adjustment 956. For example, when the material-separating damper 955 includes one or more plastic wheels, the amount of resistance of the material-separating damper 955 against the workpiece 930 may be adjusted by adjusting the gap between the plastic wheels and the material-separating channel 951-1, thereby facilitating optimal damping. As shown in fig. 14, the damping resistance adjustment device 956 adjusts the gap between the feed damping device 955 and the feed channel 951-1 by a linear movement mechanism. The linear moving mechanism can adopt a conventional linear moving adjusting mechanism with a screw penetrating through a spring. More specifically, the damping resistance adjustment device 956 includes a damping adjustment device guide support unit 956-1, a damping adjustment device spring 956-2, and a damping adjustment device adjustment screw 956-3. The damping adjustment device guide support unit 956-1 may employ a conventional linear guide (including a guide rail and a slider). The feed damping device 955 is fixedly connected with the linearly moving part of the damping resistance adjusting device 956, the adjusting screw 956-3 of the damping adjusting device passes through the spring 956-2 of the damping adjusting device and can drive the linearly moving part of the damping resistance adjusting device 956 to linearly move, so that the gap between the feed damping device 955 and the feed channel 951-1 is adjusted, and the spring 956-2 of the damping adjusting device can adjust the acting force of the linearly moving part of the damping resistance adjusting device 956 relative to the fixed part and is favorable for the timely reset of the linearly moving part of the damping resistance adjusting device 956.
In another embodiment, when the material separating damper 955 includes two or more plastic wheels, the rotational resistance of the plastic wheels is adjusted by adjusting the linear distance between the plastic wheels.

The detector 963 and the probe 961 are a detector and a probe thereof corresponding to the required detection parameters, respectively. The probe 961 is secured to the probe base 962. The detector 963 may be fixed on the probe base 962, or may be separated from the probe base 962 and close to other control systems or electronic control modules, and the detector 963 and the probe 961 are connected by a dedicated cable and transmit detection signals.
In one embodiment, the workpiece 930 is a ceramic heater chip, the detection parameter is resistance, and accordingly, the detector 962 is a conventional resistance detector and the probe 961 is a dedicated probe of a conventional resistance detector.

The contact position of probe 961 can be adjusted by probe adjustment stage 964 to be aligned with the inspection site of workpiece 930. In one embodiment, the probe adjustment stage 964 is a conventional XY two-axis manual adjustment stage or an XYZ three-axis manual adjustment stage of the prior art, and may also be an electric XYZ three-axis adjustment stage or an XY two-axis adjustment stage.
In one embodiment, the automatic sorting mechanism of one embodiment of the present invention includes a feeding module 940, a main channel 901, a sub-channel 902, a toggle mechanism 910, and a sorting and storing device 903. The workpiece 930 is manually fed into the feeding module 940 and automatically slides into the main channel 901, and then after manually identifying and determining which sorting storage device 903 the workpiece 930 should be sorted into, the workpiece 930 is pushed by the pushing mechanism 910 to reach the corresponding secondary channel 902 through the main channel 901, and finally slides into the sorting storage device 903 through the secondary channel 902.
In one embodiment, as shown in fig. 16, the automatic sorting mechanism further includes a material distribution module 950. After the workpiece 930 is manually fed into the feeding module 940, the workpiece is automatically distributed through the distributing module 950 and enters the main channel 901.
In one embodiment, as shown in fig. 16, the automatic sorting mechanism further comprises a detection module 960. After the workpiece 930 is automatically distributed by the distributing module 950 and enters the main channel 901, the detecting module 960 replaces manual identification to detect, classify and determine which sorting storage device 903 the workpiece 930 should be sorted to, and then the workpiece 930 reaches the corresponding sub-channel 902 through the main channel 901 under the pushing and pulling of the shifting mechanism 910, and finally slides into the sorting storage device 903 through the sub-channel 902.
The automatic sorting mechanism further comprises an auxiliary component used for ensuring the normal operation of the system. The auxiliary components comprise a rack, a hood, an electric cabinet, a power supply device, a control device, an air supply device and the like, and the conventional components are specifically selected according to specific requirements or can be specifically implemented after being correspondingly modified by combining the specific implementation mode on the basis of the conventional prior art.
