As shown in fig. 18, a schematic view of a part after molding and demolding is shown, which includes a product 61 and a product frame 62. Wherein the product 61 is used for subsequent assembly into an electronic product or other device, and the product frame 62 is used for assisting the product 61 to be demoulded during forming. Therefore, the product 61 needs to be cut and separated from the product frame 62 for subsequent assembly. The product 61 may be a component of an electronic product, and because the component of the electronic product is small in volume, the product frame 62 is required to assist in demolding during molding. The product 61 may be another component that needs to be separated from the product frame 62 during assembly, and may be a component used in a precision instrument or a mechanical device, for example. The embodiment of the invention provides a cutting device which can be used for cutting and separating a product 61 and a product frame 62:
fig. 1-17 are schematic views of a cutting device according to an embodiment of the invention. As shown in fig. 1 to 2, the cutting device includes a feeding mechanism 1, a carrier 2, a frame 3, a cutting mechanism 4, and a pressing mechanism 5. The feed mechanism 1 comprises a feed track 11 extending in a feed direction X. The carrier 2 is movably arranged on the feeding track 11 and can move along the feeding track 11, and the carrier 2 is used for bearing the products 61 and the product frame 62. The frame 3 is vertically arranged above the feeding mechanism 1. The cutting mechanism 4 includes a cutting blade 41 and a blade adjusting mechanism 42 connected to the cutting blade 41, and the blade adjusting mechanism 42 is disposed on the frame 3 and configured to adjust the movement of the cutting blade 41 between a first position and a second position. The pressing mechanism 5 includes a pressing driving member 51, a pressing plate 52 connected to the pressing driving member 51, and a displaced pressing assembly 53 connected to the pressing plate 52, and the pressing driving member 51 is disposed on the frame 3 and configured to drive the pressing plate 52 to press down after the carrier 2 is fed to a predetermined position.
When the cutter 41 is located below the lower pressing plate 52 at the first position, the lower pressing driving member 51 drives the lower pressing plate 52, and the lower pressing plate 52 can drive the cutter 41 to cut. When the cutting knife 41 is located at the second position, the cutting knife 41 is located at the side of the lower pressing plate 52, and the lower pressing plate 52 cannot drive the cutting knife 41 to press down.
When the lower pressing plate 52 is driven to press down by the pressing driving member 51, the misplaced pressing assembly 51 thereon can be driven to synchronously press down, and when the lower pressing plate is pressed down to the carrier 2, the misplaced pressing assembly 53 can press the product 61 on the carrier 2 and drive the product frame 62 on the carrier 2 to be misplaced with the product 61 up and down. Meanwhile, the lower pressing plate 52 can press down the cutter 41 at the first position, so that the cutter 41 cuts the product 61 while the product 61 is misaligned with the product frame 62, and the product 61 is separated from the product frame 62.
As shown in fig. 2, in some embodiments, the feed track 11 includes a first lead screw 111 and a first lead screw bearing 112. The first lead screw 111 extends along the feeding direction X and is driven by the feeding motor 113 to rotate, the first lead screw bearing 112 is sleeved on the first lead screw 111, and the first lead screw 111 and the first lead screw bearing 112 are connected through threads. The carrier 2 is disposed on the first lead screw bearing 112. The first lead screw bearing 112 and/or the carrier 2 may not be rotatable relative to the first lead screw 111, so that when the first lead screw 111 rotates, the first lead screw bearing 112 and the first lead screw 111 may move linearly under the matching of the threads, and then feed along the feeding direction X. For example, two sides of the carrier 2 may respectively have a feeding slide assembly 115, the feeding slide assembly 115 may be disposed on a machine table (not shown) or a working table (not shown), and the feeding slide assembly 115 extends along the feeding direction X. Two ends of the carrier 2 are respectively slidably disposed on the feeding slide rail assemblies 115 at two sides thereof, and the first lead screw bearing 112 is fixedly connected with the carrier 2, so that the first lead screw bearing 112 cannot rotate, and when the first lead screw 111 rotates under the driving of the feeding motor 113, the carrier 2 and the first lead screw bearing 112 can perform a feeding motion along the feeding slide rail assemblies 115 under the threaded cooperation of the first lead screw bearing 112 and the first lead screw 111.
As shown in fig. 3-6, in some embodiments, the vehicle 2 includes a floor 21, a floating mounting plate 22, and product support columns 25. The bottom plate 21 is movably arranged on the feeding track 11. The floating installation plate 22 is located above the bottom plate 21 and is connected to the bottom plate 21 in a floating manner up and down by a first elastic member 23. The upper surface of the floating installation plate 22 has an installation region 221 for installing the product frame 62, and the product 61 may be installed in the installation region 221 together with the product frame 62. The floating mounting plate 22 is further provided with a first fixing member 24, and the first fixing member 24 is used for fixing the product frame on the floating mounting plate 22. The bottom end of the product support column 25 is installed on the bottom plate 21, the top end of the product support column 25 penetrates through the floating installation plate 22 and penetrates out of the upper surface of the floating installation plate 22, and the product 61 is supported on the product support column 25.
When the offset pressing component 53 and the cutting knife 41 are pressed down to the carrier 2 by the driving of the pressing plate 52, the offset pressing component 53 can continue to press down and push the floating mounting plate 22 to press down. Since the floating mounting plate 22 is floatingly connected to the bottom plate 21 by the first elastic member 23, the floating mounting plate 22 can be pressed down by the offset pressing assembly 53. Since the floating installation plate 22 is fixed with the product frame 62 through the first fixing member 24, the product frame 62 also moves downward along with the floating installation plate 22 under the driving of the offset pressing assembly 53. Because the product 61 is supported on the product supporting column 25, the bottom end of the product supporting column 25 is fixed on the bottom plate 21, and the top end of the product supporting column 25 is penetrated through the floating installation plate 22, the product supporting column 25 is fixed when the floating installation plate 22 floats, and the product 61 is also fixed. Thereby, a height difference between the product frame 62 and the product 61 can be generated, and further, the product can be separated by cutting with the cutter 41.
Wherein, it is easily understood that the cutting knife 41 is aligned with the connection of the product 61 and the product frame 62 when the offset press-down assembly 53 is pressed down.
Wherein the first elastic member 23 may be a spring, and the first elastic member 23 may have one or more. For example, the first elastic members 23 may have four and are respectively connected to the bottom plate 21 and the floating installation plate 22 in the vicinity of four corner regions, so that the floating installation plate 22 is more uniformly stressed and moves more smoothly when floating.
As shown in fig. 9, in some embodiments, the first fixing member 24 includes a main body portion 241, a fixing portion 242 located at an end of the main body portion 241 facing the mounting region 221, and an extending portion 243 extending downward from the main body portion 241. And the floating installation plate 22 has a groove 2c on one side of the installation region 221, and a rotation shaft 2d is provided in the groove 2 c. The extending portion 243 of the first fixing member 24 is located in the recess 2c and rotatably connected to the rotating shaft 2d, and the main body portion 241 and the fixing portion 242 of the first fixing member 24 are located above the recess 2 c. Thereby, the first fixing member 24 can rotate around the rotating shaft 2d to open and close above the floating installation plate 22. When the first fixing member 24 is closed, the fixing portion 242 is located above the mounting region 221, and the product frame 62 can be pressed and fixed on the mounting region 221 through the fixing portion 242, so that the product frame 62 is not displaced or shaken. When the first fixing member 24 is opened, the fixing portion 242 is spaced apart from the installation region 221 by a sufficient distance so that the product frame 62 can be removed from the installation region 221, or the product frame 62 can be installed into the installation region 221.
As shown in fig. 5-8, in some embodiments, the carrier 2 may also include a restraint bar 26 and a check block 27. The limiting rod 26 extends downwards from the lower surface of the floating installation plate 22 and is movably arranged in the bottom plate 21 in a penetrating way. The check block 27 is movably embedded in the bottom plate 21. The stop rod 26 is connected to the check block 27 to limit the movement of the floating mounting plate 22.
Specifically, the limiting rod 26 includes a lower end far from the floating mounting plate 22, the lower end is convexly formed with a first limiting bump 261 to the side, one side of the first limiting bump 261 is formed as a first wedge surface 262, and since the first limiting bump 261 protrudes from the limiting rod 26, a sliding groove 263 which is located on the limiting rod 26 and is recessed inwards relative to the first limiting bump 261 is provided above the limiting rod. The check block 27 includes a check body 271 and a second limit protrusion 272 formed by the check body 271 protruding to one side, and one side of the second limit protrusion 272 is formed as a second wedge 273 corresponding to the first wedge 262, and the second limit protrusion 272 is spaced apart from the lower end surface of the check body 271 by a distance, thereby forming a limit space V below the second limit protrusion 272. A second elastic element 28 is connected between the check body 271 and the bottom plate 21, and the second elastic element 28 is used for resetting the check block 27 after the check rod 26 gives way.
Wherein, in an alternative implementation, the limiting rod 26 can be fixed on the lower surface of the floating installation plate 22 by a fastener.
When the offset pressing assembly 53 is not pressed to the carrier 2 and the product frame 62 is not driven to be offset from the product 61, the first limit protrusion 261 is located right above the second limit protrusion 272 and spaced apart from the second limit protrusion. When the offset pressing component 53 presses down to drive the floating mounting plate 22 to float towards the bottom plate 21, the floating mounting plate 22 drives the limiting rod 26 to press down synchronously, the first wedge surface 262 of the limiting rod 26 contacts with the second wedge surface 273 of the check block 27, and the check block 27 is pushed to move towards the side under the cooperation of the wedge surfaces, so that the limiting rod 26 is pressed down continuously, and the floating mounting plate 22 can also be pressed down continuously. When the limiting rod 26 continues to be pressed downwards until the first limiting bump 261 on the limiting rod moves to the position below the second limiting bump 272 of the check block 27, the limiting rod 26 does not push the check block 27 to the side any more, so that the check block 27 is reset under the action of the second elastic piece 28, and when the check block is reset, the limiting rod 26 avoids the reset of the check block 27 through the sliding groove 263, so that the second limiting bump 272 of the check block 27 extends into the sliding groove 263 to avoid the position. Meanwhile, the first limit projection 261 of the stopper rod 26 enters the limit space V after moving under the second limit projection 272 of the check block 27. From this, the second spacing lug 272 supports in the top of first spacing lug 261, retrains the motion of first spacing lug 261 for gag lever post 26 can not upwards float, and can keep the position after floating down, and then makes the product frame 62 on the mounting panel 22 that floats also can keep the position after floating down, prevents that the mounting panel 22 that floats from kick-backing and influencing product positioning accuracy, and is convenient for cut and take away product 61 after finishing.
Here, the check body 271 of the check 27 may have an elongated structure, and the cross section of the check 27 may have different shapes and sizes in the length direction. For example, as shown in fig. 8, the cross-sectional area of the check body 271 is larger at both ends and smaller at the middle portion, so that a groove-shaped structure is formed at the middle portion, and the second limit projection 272 is formed by a lateral protrusion in the groove-shaped structure of the middle portion, so that the second limit projection 272 has a relief space V 'at one side in the length direction of the check body 271, and the relief space V' is used for the first limit projection 261 to pass through when the stopper rod 26 moves downward.
As shown in fig. 6 and 8, in some embodiments, check body 271 includes opposing first and second ends 2711 and 2712. One end of the second elastic member 28 is connected to the first end 2711 of the check body 271, and the other end of the second elastic member 28 abuts against the bottom plate 21. Also, as described above, check body 271 may vary in cross-sectional shape and size along its length, i.e., along first end 2711 to second end 2712. For example, in fig. 8, the cross-sectional area of the first end 2711 is greater than the cross-sectional area of the second end 2712. Since the bottom plate 21 is further provided with a product supporting column 25, a limiting rod 26, a guide post 29 and the like, in practical situations, it is necessary to consider that the check block 27 does not touch other parts in the bottom plate 21 during movement. Thus, the cross-sectional shape and size of the check block 27 may vary depending on the application to ensure that it contains other components during movement.
As shown in fig. 1, 2, 6 and 8, further, the second end 2712 of the check body 271 extends out of the base plate 21, and one end of the feed rail 11 is provided with a carrier return 114, and the second end 2712 of the check body 271 extends out of the base plate 21 toward the carrier return 114. After the products 61 on the carrier 2 are separated from the product frame 62, it is easy to understand that the limiting rod 26 is still supported by the check block 27 and is in a sinking state, at this time, the carrier 2 can continue to move along the feeding track 11 toward one end of the carrier resetting member 114 until moving to the carrier resetting member 114, and the second end 271 of the check body 271 touches the carrier resetting member 114 and is pushed back by the carrier resetting member 114. After the check block 27 is pushed back, the second limit protrusion 272 will displace synchronously and leave the position right above the first limit protrusion 261, so as to let the first limit protrusion 261 move, and at this time, the limit rod 26 can move upwards without being blocked by the check block 27. Then, the floating installation plate 22 can move upward under the driving of the first elastic member 23, and return to the initial position to complete the reset.
As shown in fig. 3 and 5, in some embodiments, guide rods 29 are also provided between the bottom plate 21 and the floating mounting plate 22. The guide bar 29 serves to guide the floating mounting plate 22 to float up and down with respect to the base plate 21. The guide rods 29 may have one or more, for example, the guide rods 29 may have four and are respectively inserted near four corner regions of the bottom plate 21 and the floating installation plate 22, thereby making the floating of the floating installation plate 22 more stable. In addition, the guide rods 29 may further include corresponding guide sleeves (not shown), that is, each guide rod 29 may be disposed on the bottom plate 21 and/or the floating mounting plate 22 through the guide sleeve, which is easily understood by those skilled in the art and will not be described herein in too much detail.
As shown in fig. 11-13, in some embodiments, the offset hold-down assembly 53 may include a second fixture 531, a compression post 532, and a positioning shaft 533. In order to clearly show the staggered pressing component 53, some structures are hidden in the figure to avoid shielding. Specifically, the feed mechanism 1 and the carrier 2 are hidden in fig. 11; fig. 12 is a sectional view taken along line C-C of fig. 11, and the cutting mechanism 4 is also hidden in fig. 12; fig. 13 shows only the second fixing member 531, the pressing post 532, and the positioning shaft 533 on the lower pressing plate 52 with other structures omitted.
The second fixing member 531 is connected to the lower surface of the lower platen 52 by a third elastic member 5311 in a vertically floating manner and extends downward. The pressing column 532 is connected to a lower surface of the lower pressing plate 52 and extends downward. The positioning shaft 533 is connected to a lower surface of the lower platen 52 and extends downward.
When the carrier 2 is fed to a predetermined position, that is, a position directly below the cutting mechanism 4 and the pressing mechanism 5, the second fixing member 531 is aligned up and down with the product support post 25 on the carrier 2, the pressing post 532 is aligned up and down with the product frame 62 on the carrier 2, and the positioning shaft 533 is aligned up and down with the positioning hole 2a on the carrier 2 (the positioning hole 2a can refer to fig. 4).
As shown in fig. 13, when the carrier 2 is fed to the predetermined position and the offset press-down assembly 53 is pressed down, the second fixing member 531 presses the product tightly against the product supporting column 25 under the compression of the third elastic member 5311, and the pressing column 532 continues to press down the product frame 62, so that the product 61 and the product frame 62 are offset up and down.
Specifically, when the offset pressing component 53 is not pressed down to the carrier 2, the elastic member 5311 is in a free extension state, and at this time, the height difference between the second fixing member 531 and the end of the pressing column 532 is the same as the height difference between the product 61 and the product frame 62 (this makes the second fixing member 531 contact the product 61 and the pressing column 532 contact the product frame 62 simultaneously when the offset pressing component 53 is pressed down to the carrier 2); when the misplaced pressing component 53 is pressed down to the carrier 2, the positioning shaft 533 extends into the positioning hole 2a to guide the misplaced pressing component 53 to continue to press down; when the misplaced pressing assembly 53 continues to press down until the second fixing member 531 contacts the product 61 and the pressing column 532 contacts the product frame 62, the pressing column 532 can continue to press down the product frame 62 and the floating mounting plate 22, and since the third elastic member 5311 is connected to the second fixing member 5311 and the product supporting column 25 is fixed on the bottom plate 21, the product 61 is clamped between the second fixing member 531 and the product supporting column 25 and cannot be pressed down, so that a height difference is generated between the product 61 and the product frame 62.
As shown in fig. 4, in some embodiments, the floating mounting plate 22 has an avoiding groove 2b, and the avoiding groove 2b may be a groove penetrating the upper and lower surfaces of the floating mounting plate 22 to avoid the positioning hole 2a of the bottom plate 21, so that the positioning hole 2a is exposed rather than blocked by the floating mounting plate 22. When the offset push-down assembly 53 is pushed down, the positioning shaft 533 can pass through the avoiding groove 2b and extend into the positioning hole 2a to guide the push-down of the offset push-down assembly 53.
Further, both sides of the bottom plate 21 may have a positioning hole 2a, respectively, and correspondingly, both sides of the floating mounting plate 22 may also have an avoiding groove 2b, respectively. Thus, when the positioning shaft 533 is guided to engage with the positioning hole 2a, the escape grooves 2b on both sides of the floating attachment plate 22 can escape from the positioning shaft 533.
As shown in fig. 10, in some embodiments, the product support column 25 also has a hollow suction hole 251. When the product 61 is fixed by being sandwiched between the second fixing member 531 and the product supporting column 25 as described above, it is understood that the product 61 covers the opening of the suction hole 251 at the top end of the product supporting column 25. The product 61 can be suction-fixed to the product support column 25 through the suction hole 251. Therefore, the product 61 can be prevented from being taken up after the second fixing part 531 is lifted up when the subsequent product is demoulded, and the product 61 can be prevented from falling off.
In an alternative implementation, the base plate 21 may have through holes (not shown) that communicate with the suction holes 251 of the product support columns 25, and a vacuum suction device may be attached to the base plate 21 to provide suction to the through holes.
As shown in fig. 1 and 14, in some embodiments, knife adjustment mechanism 42 includes a knife adjustment motor 421 and a knife adjustment slide 422. Wherein fig. 14 is a perspective view of an angle of the cutting device taken in the same manner as the section C-C in fig. 11-12 is obtained, and the feed mechanism 1, the push-down mechanism 5, etc. are hidden in fig. 14 to clearly show the cutter adjustment mechanism 42. The cutter adjusting motor 421 and the cutter adjusting slide rail 422 are both disposed on the frame 3, and the cutter 41 can move along the cutter adjusting slide rail 422 under the driving of the cutter adjusting motor 421, so as to move between a first position and a second position.
As shown in fig. 15, in some embodiments, a lower pressing rail 54 is further provided between the frame 3 and the lower pressing plate 52, and the lower pressing plate 52 is slidably disposed on the lower pressing rail 53. The lower pressing plate 52 may be a rectangular plate, the lower pressing rail 54 may be located at the side of the lower pressing plate 52 in the length direction, and the second position of the cutting knife 41 may be located at the side of the lower pressing plate 52 in the width direction, thereby preventing the mechanisms from interfering with each other.
As shown in fig. 14-17, in some embodiments, the cutting mechanism 4 further includes a cutter hold-down slide 431 and a cutter attachment block 432. In fig. 16 and 17, some other structures are omitted for clarity of illustration of the structure and operation of the cutter portion. The cutter downward-pressing sliding rail 431 is slidably disposed on the cutter adjusting sliding rail 422, the cutter connecting block 432 is slidably disposed on the cutter downward-pressing sliding rail 431, the cutter connecting block 432 extends toward the downward-pressing plate 52 to form a downward-pressing follow-up portion 4321, and the cutter 41 is connected to the downward-pressing follow-up portion 4321. The cutter pressing slide rail 431 can move along the cutter adjusting slide rail 422 to drive the pressing follow-up portion 4321 of the cutter connecting block 432 to extend into or out of the lower portion of the lower pressing plate 52, and further drive the cutter 41 to move between the first position and the second position. The cutter connecting block 432 can move along the cutter pressing slide rail 431 to drive the cutter 41 to press downwards for cutting.
As shown in fig. 17, in some embodiments, tool adjustment sled 422 is slidably disposed with tool adjustment sled 4221, and tool hold-down sled 431 is coupled to tool adjustment sled 4221 and is capable of sliding along tool adjustment sled 422.
A fourth elastic element 44 for driving the cutter 41 to move upwards and return is connected between the cutter connecting block 432 and the sliding block 4221. For example, the fourth elastic member 44 may be a spring, and when the cutter 41 is pushed down by the lower pressing plate 52, the cutter connecting block 432 slides down along the cutter pushing slide rail 431 and is pushed down synchronously with the cutter 41, which stretches the fourth elastic member 44; after the cutting is finished, the cutter 41 moves from the first position to the second position, and the fourth elastic member 44 is compressed spontaneously from the stretched state, so as to drive the cutter connecting block 432 to slide upwards along the cutter downward-pressing sliding rail 431, and drive the cutter 41 to move upwards and reset.
As shown in fig. 17, in some embodiments, a knife adjustment motor 421 and a knife adjustment slide 422 are respectively disposed on both sides of the frame 3.
