The moving element mentioned in the embodiment is specifically two driving cylinders, namely a long-stroke cylinder 12 and a short-stroke cylinder 11, the short-stroke cylinder 11 is fixed on a sliding seat of the long-stroke cylinder 12, and meanwhile, the feeding table 10 is fixed at the output end of the short-stroke cylinder 11; it should be noted that the extension and retraction direction of the extension and retraction shaft of the short stroke cylinder 11 is perpendicular to the sliding direction of the sliding seat of the long stroke cylinder 12, so that the long stroke cylinder 12 and the short stroke cylinder 11 can move the feeding table 10 in any direction of the plane.

In the specific design and application process, the long-stroke cylinder 12 and the short-stroke cylinder 11 can be replaced by linear electric cylinders, lead screw motors or oil cylinders.

In order to enable the automatic assembly mechanism of the components to be overlapped on the feeding table 10 more smoothly and conveniently, optionally, a component carrying mechanism is further provided between the component feeding mechanism and the automatic assembly mechanism, that is, it can be understood that the components overlapped on the feeding table 10 can be carried to the automatic assembly mechanism by using the component carrying mechanism.

Specifically, referring to fig. 4, the component conveying mechanism provided in this embodiment includes a conveying driver 20, a first clamp 21-1 and a second clamp 21-2, where the first clamp 21-1 and the second clamp 21-2 are movably disposed relatively to each other to clamp the overlapped components 300 on the feeding table 10; the carrying driver 20 is mainly used to enable the first clamp body 21-1 and the second clamp body 21-2 to move on a vertical plane before the clamping assembly 300 and after the clamping assembly 300, so as to conveniently clamp and place the assembly 300.

The movement in the vertical plane mentioned here is specifically that before the component 300 is gripped, the conveying driver 20 drives the first clamp body 21-1 and the second clamp body 21-2 to move above the component 300 and then descend, the first clamp body 21-1 and the second clamp body 21-2 move relatively to grip the overlapped component 300, and then the conveying driver 20 drives the first clamp body 21-1 and the second clamp body 21-2 to move after ascending, and such gripping movement can convey the component 300 from the feeding table 10 to the automatic assembly mechanism.

Optionally, in order to reduce the weight of the first clamp 21-1, reduce the output force of the conveying driver 20 and improve the conveying efficiency, a weight-reducing groove 21-1C is further provided in the middle of the first clamp 21-1, and an auxiliary supporting member 21-1D for supporting the lifting assembly 300 is provided on the groove wall of the weight-reducing groove 21-1C; meanwhile, as the second clamp body 21-2 has the same structure as the first clamp body 21-1, a weight reduction groove and an auxiliary support piece are also arranged at the middle position of the second clamp body 21-2 to be matched with the weight reduction groove 21-1C and the auxiliary support piece 21-1D on the first clamp body 21-1, so as to ensure the stability of the overlapping assembly 300 when the assembly 300 is clamped and carried.

In the present embodiment, referring to fig. 4, the carrying driver 20 is composed of two cylinders, including a lifting cylinder and a translation cylinder, wherein the translation cylinder is disposed on the lifting cylinder; and the relative motion between the first clamp body 21-1 and the second clamp body 21-2 is realized through a clamping finger cylinder which is fixed on a translation cylinder, so that the first clamp body 21-1 and the second clamp body 21-2 are driven by the clamping finger cylinder to make corresponding movement through the lifting movement of the lifting cylinder and the translation movement of the translation cylinder, so as to smoothly clamp the component 300 on the feeding table 10.

The component conveying mechanism conveys the component 300 on the feeding table 10 to the automatic assembly mechanism, specifically, the automatic assembly mechanism comprises an assembly table 30 and a screw locker 31, wherein two ends of the assembly table 30 are respectively provided with a front end limiting part 30-1 and a tail end limiting part 30-2, the front end limiting part 30-1 and the tail end limiting part 30-2 are of U-shaped structures and have opposite openings, and the front end limiting part 30-1, the assembly table 30 and the tail end limiting part 30-2 jointly form a containing cavity for positioning the component 300; the accommodating cavity is positioned below the first clamp body 21-1 and the second clamp body 21-2, so that after the first clamp body 21-1 and the second clamp body 21-2 clamp the assembly 300, the assembly 300 can be placed in the accommodating cavity under the matching driving of the carrying driver 20 and the clamping finger air cylinder; the cavity is mainly used to ensure the stability and positioning of the assembly 300, and to provide better assurance for the subsequent assembly of the screws.

In the embodiment, referring to fig. 5, because the tail end limiting portion 30-2 is disposed on the assembly table 30, in order to match the structure therein, a clearance gap 21-1E corresponding to the tail end limiting portion 30-2 is disposed in the tail end clamping groove 21-1B of the first clamp body 21-1, and similarly, a clearance gap is also disposed on the second clamp body 21-2, when the two clamp bodies are combined, the two clearance gaps are matched to form clearance for the tail end limiting portion 30-2.

Referring to fig. 6-7, the screw locking device 31 mainly acts on the second screw 200 (long screw), the screw locking device 31 is disposed above the cavity and can move up and down, and the screw locking device 31 has a magnetic locking head 31-1, the locking head 31-1 is adapted to the second screw, that is, the locking head 31-1 can act on the second screw 200, the locking operation of the second screw and the first screw is realized by using the locking head 31-1, the locking head 31-1 has magnetism so as to ensure the stability of the connection between the second screw and the locking head 31-1, and the falling of the second screw 200 is avoided by means of magnetic attraction.

In this embodiment, the up-and-down movement of the screw locking device 31 is realized by a vertical driver 32, where the vertical driver 32 may be a linear driving device such as an air cylinder, a linear motor or an electric cylinder, and the screw locking device 31 is fixedly disposed on an output shaft of the vertical driver 32.

Optionally, the automatic assembly mechanism further includes a support plate 33, the above-described vertical driver 32 is fixed on the support plate 33, and the support plate 33 is utilized to form a stable and effective support, so as to facilitate automatic operation of the vertical driver 32 and the screw locker 31;

meanwhile, considering that the output of the vertical driver 32 is often accompanied by vibration, in order to ensure the stability of the screw locking device 31 in the up-and-down moving process, a vertical sliding rail 34-1 and a first sliding seat 34-2 capable of sliding on the sliding rail 34-1 are further arranged on the support plate 33, a switching block 34-3 is fixed on the first sliding seat 34-2, the output end of the vertical driver 32 is fixed with the switching block 34-3, and the screw locking device 31 is fixed with the switching block 34-3; by means of the switching, the screw locking device 31 is not directly fixed with the output shaft of the vertical driver 32 to reduce the transmission of the vibration frequency, and simultaneously, the stability of the screw locking device 31 in the up-and-down sliding process is ensured by the matching of the slide rail and the slide seat,

optionally, a second sliding seat 34-4 is further provided on the sliding rail 34-1, where the second sliding seat 34-4 is spaced from the first sliding seat 34-2 and located below the first sliding seat 34-2, and a buffer block 34-5 is provided on the second sliding seat 34-4, and the buffer block 34-5 is elastically connected to the adapting block 34-3 through an elastic member 34-6; while the locking head 31-1 of the screw locker 31 extends downward and passes through the buffer block 34-5.

By means of the elastic connection between the buffer block 34-5 and the adapter block 34-3, the buffer block 34-5 directly acts on and abuts against the component 300 after the screw locking device 31 descends, so that the screw locking device 31 can further stabilize the component 300 on the assembly table 30 during assembly.

Optionally, the elastic member 34-6 is a spring.

In this embodiment, referring to fig. 6, the mounting table 30 and the supporting plate 33 are both movable in the horizontal plane, because there are five mounting holes in the assembly 300 at different positions, and in order to ensure that the screws can be quickly and stably mounted in the five mounting holes, the supporting plate 33 and the mounting table 30 need to be adjusted and moved to ensure the processing precision, so as to complete the positioning processing.

Because the assembly table 30 provided by the present embodiment is movable, when the first clamp 21-1 and the second clamp 21-2 in the component conveying mechanism clamp the component 300 for conveying, the assembly table 30 can move to a position right below the first clamp 21-1 and the second clamp 21-2, so that the first clamp 21-1 and the second clamp 21-2 can be quickly and stably placed in the accommodating cavity on the assembly table 30 after clamping the component 300 on the feeding table 10.

Considering that the assembly table 30 has a plurality of position points, in order to ensure the moving precision and the position precision of the assembly table 30, the ball screw module is adopted to control the movement of the assembly table, so that the high-precision positioning of five mounting holes of the assembly is realized, and the smooth screw installation is ensured.

The second screw 200 is fed by a second screw feeding mechanism, so that the second screw 200 can be magnetically attracted to the locking head 31-1 of the screw locker 31.

Specifically, referring to fig. 2 and 8, the second screw feeding mechanism includes a second screw guiding member 40, a second screw transferring member 41 and a second screw lifting member 42; the second screw 200 can be smoothly and stably supplied to the locking head 31-1 of the screw locker 31 through the second screw guide 40, the second screw transfer 41 and the second screw raising 42.

The second screw guide member 40 has a guide groove 40-1 for receiving and guiding the second screw 200, wherein the guide groove 40-1 is a U-shaped guide groove with an upward opening, so that when the screw is guided, the screw portion of the second screw 200 is located in the guide groove 40-1, and the nut portion of the second screw 200 is located outside the guide groove 40-1; through the U-shaped structural design of the guide groove 40-1, the second screws can be smoothly fed.

After the second screw 200 is guided to a predetermined position on the guide groove 40-1, the second screw transfer member 41 starts to work to transfer the second screw 200; specifically, the second screw transfer member 41 includes a rotary driver 41-1 and second screw clamping rods 41-2 disposed on the rotary driver 41-1, the second screw clamping rods 41-2 are disposed in pairs on the rotary driver 41-1, and each of the second screw clamping rods 41-2 is provided with a clamping slot 41-3, and the two second screw clamping rods 41-2 in each pair are movably disposed relative to each other such that the two clamping slots 41-3 form a clamping position for clamping the second screw 200.

That is, it can be understood that, after the second screw 200 is guided to the predetermined position in the guide groove 40-1, the two second screw clamping rods 41-2 in the second screw transfer member 41 move relatively to clamp the second screw 200 out of the guide groove 40-1, and then the clamped second screw 200 is sent to the upper side of the second screw lifting member 42 under the rotation action of the rotary driver 41-1.

In this embodiment, the rotary driver 41-1 is a rotary cylinder, and the second screw clamping rods 41-2 are provided in pairs, specifically, two pairs of second screw clamping rods 41-2 may be provided on the rotary cylinder, each pair being provided at two ends of the rotary cylinder, and the rotary cylinder rotates to clamp the second screws 200, which can switch the pair of second screw clamping rods 41-2 back and forth.

In this embodiment, the clamping operation of the two second screw clamping rods 41-2 in each pair is performed by a clamping finger cylinder disposed on the rotating cylinder, that is, one second screw clamping rod 41-2 is fixed to each clamping jaw of the clamping finger cylinder, so that the two second screw clamping rods 41-2 move relatively to each other by the action of the clamping finger cylinder, thereby clamping the second screws.

When the pair of second screw clamping rods 41-2 clamps the second screw, the rotary driver is activated to rotate the clamped second screw 180 ° above the second screw lifting piece 42, and because the second screw lifting piece 42 is disposed below the screw locking device 31, it can be understood that the clamped second screw 200 is rotated between the second screw lifting piece 42 and the screw locking device 31; and lifting the second screw to the position of the screw locking device 31 by using the second screw lifting piece 42, enabling the locking head of the screw locking device 31 to suck the second screw 200, and after the first screw 100 is in place, driving the second screw 200 to be matched with the first screw 100 by the locking head 31-1, thereby completing the assembly.

Specifically, referring to fig. 2 and 9, the second screw jacking member 42 includes a jacking driver 42-1 and a second screw placing seat 42-2 provided with an output end of the jacking driver 42-1, and a placing groove adapted to a screw rod portion of the second screw 200 is provided in the second screw placing seat 42-2; the purpose of the placing groove is to ensure that the second screw 200 can be stably placed in the placing groove until being jacked to the locking head 31-1 in the jacking action of the jacking driver 42-1.

The specific feeding operation of the second screw 200 is: the second screw 200 is conveyed to a predetermined position to be gripped by conduction through the guide groove 40-1 in the supply tray; a clamping finger cylinder in the second screw transferring part 41 drives a second screw clamping rod 41-2 to move relatively to clamp a second screw 200 on a position to be clamped, then a rotary driver 41-1 starts to rotate for 180 degrees, the clamped second screw 200 is rotated to a position right above a second screw jacking part 42, and then the clamping finger cylinder is loosened, so that the second screw 200 falls into a placing groove of a second screw placing seat 42-2 in the second screw jacking part 42; at this time, the jacking driver 42-1 starts to move and extend, so that the second screw 200 is jacked to the locking head 31-1 of the screw locker 31, and the second screw 200 can be magnetically attracted to be kept waiting for being matched with the first screw 100 because the locking head 31-1 has magnetism; the jacking driver 42-1 retracts to the initial position after the second screw is attracted by the magnet, and waits for the next jacking.

When the second screw 200 is fed, the first screw 100 is also fed synchronously by the first screw feeding mechanism.

Specifically, referring to fig. 10 to 11, the first screw feeding structure includes a transfer chute 51, and one end of the transfer chute 51 is disposed right below the assembly table 30; a first slidable screw placing seat 52 is arranged in the transfer chute 51; meanwhile, a pushing piece 53 for pushing the first screw placing seat 52 is also arranged on the transferring slideway 51; the first screw 100 is conveyed by the transfer jaw 54 provided above the transfer chute 51, and the transfer jaw 54 can move up and down, left and right.

The entire automated assembly operation can be summarized as: the transferring clamping claw 54 picks the first screw 100 from the feeding disc and then acts to place the picked first screw 100 on the first screw placing seat 52, and then the pushing member 53 linearly pushes the first screw placing seat 52 with the first screw 100 to move on the transferring slideway 51, and stops pushing when pushing the transferring clamping claw to the position right below the assembling table 30; at this time, the first screw placing seat 52 is located right above the first screw jacking piece 55, and then the assembly table 30 starts to move under the control of the ball screw module, so as to ensure that the mounting holes of the components 300 on the assembly table 30 correspond to the first screws 100 and the second screws 200; the first screw raising member 55 then starts a raising action on the first screw seat 52 so that the first screw 100 can be raised through the mounting hole of the assembly 300, while the vertical driver 32 drives the screw locker 31 with the second screw 200 down so that the second screw 200 is in facing engagement with the first screw 100, and then the screw locker 31 is activated so that the second screw 200 is screwed into the first screw 100, thereby completing the assembly of one of the mounting holes of the assembly.
