The feeding mechanism 20 includes an installation box 21, and the installation box 21 is arranged on the upper surface of the workbench 10. A partition 22 is provided inside the installation box 21, and the side wall of the installation box 21 and the partition 22 are connected. A first slide bar 23 is provided between the mounting box 21 and the mounting box 21, wherein the first slide bar 23 is provided with two groups, and the circumferential surface of the first slide bar 23 is slidably connected with a first slide plate 24, and the two groups of first slide bars 23 are respectively located at both ends of the first slide plate 24, which can play a role in stably supporting the first slide plate 24, and a first servo electric cylinder 26 is provided on the side of the mounting box 21, and the output end of the first servo electric cylinder 26 is connected to the first slide plate 24, and a first slide rail 25 is provided on the upper surface of the first slide plate 24, and a first slider 27 is slidably connected to the surface of the first slide rail 25, and the first slider The upper surface of the mounting box 21 is provided with a movable slide 28, wherein the first slide block 27 and the movable slide block 28 are provided with two groups and are symmetrically arranged, the interior of the mounting box 21 is provided with a second slide bar 29, wherein the second slide bar 29 is provided with two groups, and the second slide bar 29 and the first slide bar 23 are arranged vertically, the circumferential surface of the second slide bar 29 is slidably connected with a second slide plate 210, the upper surface of the second slide plate 210 is slidably connected with a fixed slide block 211, and the fixed slide block 211 is fixedly arranged on the surface of the movable slide block 28, and the side of the second slide plate 210 is provided with a triangular The sliding frame 212, wherein the second sliding plate 210, the fixed sliding block 211, and the triangular sliding frame 212 are each provided with two groups and are symmetrically arranged, the interior of the triangular sliding frame 212 is slidably connected with a connecting slide 213, the interior of the triangular sliding frame 212 is provided with a limiting slide rail 214, and the connecting slide 213 is slidably connected to the limiting slide rail 214, wherein the connecting slide 213 is slidably connected to both triangular sliding frames 212, and is limited by the limiting slide rail 214, so that the connecting slide 213 only slides inside the triangular sliding frame 212.

[0036] It should be noted that the first slide bar 23, the first slide plate 24, the first slide rail 25, and the first slider 27 are arranged on the right side of the upper surface of the workbench 10, and the upper surfaces of the two first sliders 27 are connected to the two movable sliders 28 for the purpose of facilitating the two movable sliders 28 to move forward and backward and left and right. When the cover plate raw material is stamped, the connecting slider 213 is moved upward inside the triangular sliding frame 212. Since the length of the connecting slider 213 is fixed and it only slides inside the triangular sliding frame 212, when the connecting slider 213 moves upward, under the action of the second slide bar 29, the two triangular sliding frames 2 12 are close to each other, and the second sliding plate 210 and the fixed sliding block 211 can provide a pulling force to move the two moving sliding blocks 28 toward the middle. Since the two ends of the two moving sliding blocks 28 are slidably connected on the first slide rail 25 through the first sliding block 27, when the two moving sliding blocks 28 have a pulling force to move toward the middle, the two moving sliding blocks 28 can be pulled to move toward the middle. When the two moving sliding blocks 28 move to a certain position toward the middle, the clamping and transporting mechanism 30 can clamp and fix the cover plate raw material placed on the loading end of the loading and unloading mechanism 50, and then the first servo electric cylinder 26 is driven to work to push the first sliding plate 24 to the first slide bar 2 3, and moves forward, at this time, the two moving slides 28 can be driven to move forward. By moving the moving slides 28 forward, the clamping and transporting mechanism 30 can transport the cover plate raw material at the feeding end of the loading and unloading mechanism 50 to the stamping position in the stamping mechanism 40. Moreover, since the clamping and transporting mechanism 30 is provided with two groups, and the other group is located at the stamping position in the stamping mechanism 40, when the clamping and transporting mechanism 30 transports the cover plate raw material at the feeding end of the loading and unloading mechanism 50 to the stamping position in the stamping mechanism 40, the clamping and transporting mechanism 30 can also transport the cover plate stamped at the stamping position in the stamping mechanism 40 to the unloading end of the loading and unloading mechanism 50, and transport After being delivered to the designated position, the connecting slide 213 can first be moved downward a certain distance, and the clamping and transporting mechanism 30 can be made to release the clamping and fixing relationship between the cover plate raw material and the cover plate, and then the first servo electric cylinder 26 is contracted to drive the moving slide 28 to start resetting. After the first servo electric cylinder 26 has completed the contraction, the connecting slide 213 is moved downward to the original position in the triangular sliding frame 212, that is, the resetting is completed. During the resetting process, the clamping and transporting mechanism 30 will also be reset. This is a cycle, and the reciprocating operation can continuously perform stamping processing on the cover plate raw materials to produce cover plates, which greatly improves work efficiency.

[0037] The clamping and shipping mechanism 30 includes a fixed plate 31, which is fixedly arranged on the surface of the movable slide 28. A first connecting slide bar 32 is provided on the upper surface of the fixed plate 31. The end of the first connecting slide bar 32 away from the fixed plate 31 is slidably connected to a sliding connection box 33, wherein the fixed plate 31 is provided with two groups and are respectively arranged on the two movable slides 28. The first connecting slide bar 32 is provided with four groups and is supported in pairs, so as to provide stable support for the sliding connection box 33. A sliding groove 34 is provided on the side of the fixed plate 31. A second slider 35 is slidably connected to the inside of the sliding groove 34. An arc-shaped clamping plate 36 is provided on the end of the second slider 35 away from the sliding groove 34. A limiting groove 37 is provided on the lower surface of the sliding connection box 33. A connecting slide column 38 is provided on the upper surface of the arc-shaped clamping plate 36, and an end of the connecting slide column 38 away from the arc-shaped clamping plate 36 is slidably connected to the limiting groove 37.

[0038] It should be noted that the working mode of the clamping and transporting mechanism 30 is that when the two movable slides 28 move toward the middle, the two fixed plates 31 can be simultaneously moved toward the middle of the sliding connection box 33, and the first connecting slide rods 32 on both sides of the sliding connection box 33 can slide toward the inside of the sliding connection box 33, and when the fixed plate 31 moves toward the middle of the sliding connection box 33, the arc-shaped clamping plate 36 can be moved in the direction of the cover plate raw material placed on the loading end of the loading and unloading mechanism 50, and under the action of the sliding groove 34, the limit groove 37 and the connecting slide column 38, the arc-shaped clamping plate 36 can also shrink and bring the cover plate raw material closer during the movement, and finally achieve the effect of clamping and fixing. Similarly, the clamping and transporting mechanism 30 arranged at the stamping position of the stamping mechanism 40 will also clamp the cover plate after stamping.

[0039] The punching mechanism 40 includes a punching frame 41, and the punching frame 41 is arranged on the upper surface of the workbench 10, and a second servo electric cylinder 42 is arranged on the lower surface of the punching frame 41, and a mounting frame 43 is arranged at the output end of the second servo electric cylinder 42, and a mounting seat 44 is slidably connected inside the mounting frame 43, and bolt grooves 46 are arranged on the sides of the mounting frame 43 and the mounting seat 44, and fixing bolts 47 are arranged at the overlapped positions of the bolt grooves 46 on the sides of the mounting frame 43 and the mounting seat 44, and a punching head 45 is arranged on the lower surface of the mounting seat 44, and a punching table 412 is arranged on the upper surface of the workbench 10, wherein The clamping and transporting mechanism 30 is provided with two groups, one group is located at the upper end of the loading and unloading mechanism 50, and the other group is located at the upper end of the stamping table 412, wherein a lifting mechanism is provided inside the stamping table 412. When the cover plate raw material is transported to the position of the stamping table 412 by the clamping and transporting mechanism 30, the stamping table 412 will drive the cover plate raw material to descend, so as to facilitate the subsequent resetting process of the clamping and transporting mechanism 30 to collide with the cover plate raw material. When the cover plate raw material is to be stamped, the lifting device inside the stamping table 412 will drive the cover plate raw material to rise for easy stamping.

[0040] It should be noted that when stamping the cover plate raw material, the second servo electric cylinder 42 can be output to make the mounting frame 43 drive the mounting seat 44 to descend, and then the punching head 45 can stamp the cover plate raw material at the position of the punching table 412. When installing and replacing the punching head 45, the fixing bolt 47 can be moved out of the bolt groove 46 first, and then the mounting seat 44 can be slid out of the mounting frame 43 to release the fixing relationship between the two, which is convenient for disassembly. When installing, the mounting seat 44 carrying the punching head 45 can be slid and installed in the mounting frame 43 first. At this time, the mounting seat 44 and the mounting frame 43 already have a certain fixed relationship, and no manual support is required, which is convenient for the subsequent use of the fixing bolts 47 to fix, thereby achieving the effect of facilitating installation.

[0041] A connecting plate 48 is provided on the upper surface of the mounting frame 43, and a second slide rail 410 is provided on the lower surface of the stamping frame 41. A second connecting slide rod 411 is slidably connected inside the second slide rail 410, and the lower end of the second connecting slide rod 411 is connected to the upper surface of the connecting slide plate 213, and a connecting coordination plate 49 is provided between the connecting plate 48 and the second connecting slide rod 411.

[0042] It should be noted that when the mounting frame 43 descends, under the action of the connecting plate 48, the second connecting slide bar 411 can slide downward inside the second slide rail 410. When the second connecting slide bar 411 slides downward, the connecting slide plate 213 can slide downward inside the triangular slide frame 212. When the stamping mechanism 40 finishes stamping, the second servo electric cylinder 42 is reset. Under the action of the connecting plate 48, the second slide rail 410 and the second connecting slide bar 411, the connecting slide plate 213 can also slide upward inside the triangular slide frame 212. This method can provide clamping and releasing force to the clamping and shipping mechanism 30, thereby reducing energy loss.

[0043] The loading and unloading mechanism 50 includes a servo motor 51, and the servo motor 51 is arranged on the lower surface of the workbench 10. The output end of the servo motor 51 is transmission-connected with a rotating rod 52. The circumferential surface of the rotating rod 52 is transmission-connected with a transmission belt 53 through a rotating wheel. The end of the transmission belt 53 away from the rotating rod 52 is transmission-connected with a threaded rod 54 through a rotating wheel. A storage box 56 is provided inside the workbench 10. A connecting slide box 55 is provided on the lower surface of the storage box 56, and the storage box 56 is communicated with the connecting slide box 55. The threaded rod 54 is located inside the connecting slide box 55 and rotates. A lifting rod 57 is threadedly connected to the circumferential surface of the threaded rod 54, and the lifting rod 57 is slidably connected to the connecting slide box 55 and the storage box 56. A lifting platform 58 is provided on the upper surface of the lifting rod 57, and the lifting platform 58 is slidably connected to the storage box 56.

[0044] It should be noted that when the loading and unloading mechanism 50 is loading and unloading, the servo motor 51 can be operated to drive the rotating rod 52 to rotate. When the rotating rod 52 rotates, the transmission belt 53 can drive the threaded rod 54 to rotate. When the threaded rod 54 rotates, and under the rotation limit of the connecting slide box 55, the lifting rod 57 can be moved up and down in the connecting slide box 55, thereby driving the lifting platform 58 to slide up and down in the storage box 56. This method can facilitate the storage and feeding of the cover plate raw materials in the storage box 56.

[0045] A driving gear 59 is provided on the circumferential surface of the rotating rod 52, and a driven gear 510 is meshedly connected to the circumferential surface of the driving gear 59. A rotating shaft 511 is transmission-connected to the middle of the upper surface of the driven gear 510, and the rotating shaft 511 is rotationally connected to the workbench 10. An end of the rotating shaft 511 away from the driven gear 510 is transmission-connected to a flow disk 512, and a material discharge trough 513 is provided inside the flow disk 512, wherein four groups of material discharge troughs 513 are equidistantly provided on the inner circumference of the flow disk 512.

[0046] It should be noted that when the rotating rod 52 rotates, it can drive the driving gear 59 to rotate. When the driving gear 59 rotates, it can drive the driven gear 510 to rotate, and then drive the flow plate 512 to rotate through the rotating shaft 511. When the flow plate 512 rotates, it is convenient for the cover plate that is clamped and consigned to the inside of the discharge trough 513 by the consignment mechanism 30 to be rotated to the unloading end for removal, and replace the new discharge trough 513. The driving gear 59 and the driven gear 510 have a transmission ratio. This transmission ratio can meet the requirement that when the threaded rod 54 rotates and the raw material of the cover plate of the storage box 56 rises by a material height under the action of the connecting slide box 55, the storage box 56, the lifting rod 57, and the lifting platform 58, that is, when the feeding of one material is completed, the flow plate 512 rotates exactly one quarter to complete the replacement of the discharge trough 513.

[0047] The working principle and use process of the present invention:

[0048] Step 1: By retracting and resetting the second servo electric cylinder 42, the connecting slide 213 can be moved upward inside the triangular sliding frame 212 under the action of the connecting plate 48, the second slide rail 410 and the second connecting slide rod 411. When the connecting slide 213 moves upward, under the action of the second slide rod 29, the two triangular sliding frames 212 can be driven to approach each other, and the two moving slides 28 can be pulled to move toward the middle. When the two moving slides 28 move to a certain position toward the middle, the clamping and transporting mechanism 30 can clamp and fix the cover plate raw material placed on the lifting platform 58 and the cover plate placed on the upper end of the stamping platform 412. The clamping process of the clamping and transporting mechanism 30 is as follows: when the two moving slides 2 When the two fixing plates 31 are moved toward the middle, the two fixing plates 31 can simultaneously move toward the middle of the sliding connection box 33, and the first connecting slide bars 32 on both sides of the sliding connection box 33 can slide toward the inside of the sliding connection box 33. When the fixing plates 31 move toward the middle of the sliding connection box 33, the arc-shaped clamping plates 36 can move in the direction of the cover plate raw material placed on the loading end of the loading and unloading mechanism 50, and under the action of the sliding groove 34, the limiting groove 37 and the connecting slide column 38, the arc-shaped clamping plates 36 can also shrink and bring the cover plate raw material closer during the movement, and finally achieve the effect of clamping and fixing. Similarly, the clamping and transporting mechanism 30 set at the stamping position of the stamping mechanism 40 will also clamp the cover plate after stamping.

[0049] Step 2, after the clamping is completed, the first servo electric cylinder 26 is operated to push the first sliding plate 24 to move forward on the circumferential surface of the first sliding rod 23, and at this time, the two moving slides 28 can be driven to move forward. By moving the moving slides 28 forward, the clamping and transporting mechanism 30 can move the cover plate raw material placed on the lifting platform 58 and the cover plate placed on the upper end of the punching platform 412 to the upper end of the punching platform 412 and the inside of the discharge trough 513 of the flow turntable 512, respectively. After transporting to the designated position, the second servo electric cylinder 42 can first drive the connecting slide 213 to move downward a certain distance. It is only necessary to enable the clamping and transporting mechanism 30 to release the clamping and fixing relationship of the cover plate raw material and the cover plate, and at the same time, the punching platform 412 drives the upper end of the cover plate raw material to descend, and then the first servo electric cylinder 26 is retracted and reset;

[0050] After the first servo electric cylinder 26 shrinks and resets, it will drive the moving slide 28 to move to the leftmost end of the workbench 10, and then the second servo electric cylinder 42 outputs, so that the mounting frame 43 drives the mounting seat 44 to descend, and then the punch head 45 punches the cover plate raw material at the position of the punching table 412. When the second servo electric cylinder 42 drives the punch head 45 to punch, under the action of the connecting plate 48, the second slide rail 410 and the second connecting slide rod 411, the connecting slide 213 will move downward to the original position in the triangular sliding frame 212, that is, the reset is completed, and then the clamping and shipping mechanism 30 is reset. This is a cycle, and the reciprocating operation can continuously punch the cover plate raw material to produce the cover plate, which greatly improves the work efficiency;

[0051] Step three, by making the servo motor 51 work, the rotating rod 52 is driven to rotate. When the rotating rod 52 rotates, the threaded rod 54 can be driven to rotate through the action of the transmission belt 53. When the threaded rod 54 rotates, and under the rotation limit of the connecting slide box 55, the lifting rod 57 can be moved up and down in the connecting slide box 55, thereby driving the lifting platform 58 to slide up and down in the storage box 56. This method can facilitate the storage and feeding of the cover raw materials in the storage box 56. When the material in the lifting platform 58 is clamped by the consignment mechanism 30 After the carrying, the loading and unloading mechanism 50 will work to drive the cover plate raw materials of the storage box 56 to rise to a material height for loading. At the same time, when the rotating rod 52 rotates, it can drive the driving gear 59 to rotate. When the driving gear 59 rotates, it can drive the driven gear 510 to rotate, and then drive the flow plate 512 to rotate through the rotating shaft 511. When the flow plate 512 rotates, it can facilitate the cover plate that is clamped and transported by the transport mechanism 30 to the inside of the discharge trough 513 to be rotated to the unloading end for removal, and replace the new discharge trough 513.
