Description

Technical Field

[0001] This application relates to the technical field of metal stamping processing, and particularly to a steel plate stamping device. Background Art

[0002] A steel plate is a flat steel product formed by pouring molten steel and pressing it after cooling. Steel plate stamping is a metal processing technology that uses the upper template and punch installed on a press to apply pressure to the steel plate material, causing the steel plate material to separate or undergo plastic deformation, thereby obtaining the required parts.

[0003] Chinese Patent No. CN206854428U discloses a steel plate stamping device, which includes a support frame, a support base, a pressing body, an elastic support body, a workpiece support plate, a punching hole, and a stamping body; the support frame is connected to the support base, the pressing body is connected to the elastic support body, the elastic support body is connected to the support frame, the workpiece support plate is connected to the support base, the punching hole is in the middle of the workpiece support plate, and the stamping body is connected to the pressing body. When stamping a steel plate, the steel plate is placed on the workpiece support plate, and the pressing body presses and drives the stamping body downward to impact the steel plate. The stamped workpiece separates from the steel plate and falls to the ground below the support base through the punching hole.

[0004] Regarding the above related technologies, the inventor found that when performing streamlined operation stamping processing on steel plates, the workpieces stamped from the steel plates are prone to scatter and accumulate on the ground below the support base. It is necessary to manually collect the scattered workpieces and transfer them to the next processing line of the workpieces, which is very labor-consuming. Summary of the Invention

[0005] In order to improve the problem of inconvenient manual collection and transfer of workpieces, this application provides a steel plate stamping device.

[0006] The steel plate stamping device provided by this application adopts the following technical solutions:

[0007] A steel plate stamping device includes a workbench and a stamping machine arranged on the workbench. A punching hole for the workpiece to fall through is perforated through the workbench; a collection pipe is arranged around the punching hole at the bottom of the workbench. One end of the collection pipe away from the workbench is provided with a bearing table for bearing the workpiece, and a conveying member for transporting the workpiece is arranged on one side of the bearing table; a control mechanism for retaining a single workpiece on the bearing table is arranged between the bearing table and the collection pipe, and a transfer assembly for transferring the workpiece from the bearing table to the conveying member is arranged on the bearing table.

[0008] By adopting the above technical solution, the collection pipeline guides the falling direction of the workpiece. At the same time, the collection pipeline gathers the workpieces, reducing the phenomenon that the workpieces scatter everywhere after hitting the bearing table, so as to facilitate the stacking of the falling workpieces on the bearing table and wait for transfer, thus realizing the rapid collection of the workpieces; the control mechanism retains the stacked workpieces on the bearing table one by one, and the transfer component transfers the workpieces on the bearing table to the conveying component for transfer, thus realizing the transfer of the workpieces to the next processing pipeline of the workpieces, and reducing the labor loss of manually collecting and transferring the workpieces.

[0009] Preferably, the control mechanism includes a mounting frame, a telescopic member and a clamping assembly; the mounting frame is located between the bearing table and the collection pipeline, the telescopic member is arranged on the side of the mounting frame away from the punching machine, the output end of the telescopic member is connected to the mounting frame, and the telescopic member is used to drive the mounting frame to move along the height direction of the bearing table; the clamping assembly is arranged on the mounting frame for clamping the workpiece.

[0010] By adopting the above technical solution, the workpieces are stacked on the bearing table, the clamping assembly clamps the stacked workpieces, and the output end of the telescopic member extends, so that the mounting frame drives the clamping assembly and the clamped workpieces to gradually move away from the bearing table to retain a single workpiece on the bearing table and wait for transfer; after the workpieces on the bearing table are transferred, control the output end of the telescopic member to contract, so that the workpieces on the clamping assembly gradually abut against the upper surface of the bearing table, and place the workpieces on the bearing table again through the clamping assembly, so as to facilitate a new round of clamping workpieces and retaining a single workpiece on the bearing table and waiting for transfer.

[0011] Preferably, a contact plate that abuts against the bottom wall of the mounting frame is arranged at the output end of each telescopic member, a limiting cylinder is arranged on the mounting frame around each group of contact plates, and a trigger switch for controlling all telescopic members to stop working is arranged on one of the limiting cylinders; a buffer space is reserved between the contact plate and the trigger switch, and when the contact plate abuts against the trigger point of the trigger switch, the trigger switch controls all telescopic members to stop working.

[0012] By adopting the above technical scheme, the limit cylinder limits the moving direction of the contact plate, reducing the phenomenon of the contact plate detaching from the mounting frame; when the output end of the telescopic member contracts to place the workpiece on the clamping assembly back on the carrier table, the workpiece abuts the upper surface of the carrier table, and the carrier table supports and fixes the workpiece, the clamping assembly and the mounting frame, and the output end of the telescopic member continues to contract; at this time, the contact plate can slide inside the buffer space, reducing the rigid collision between the telescopic member and the mounting frame in the process of the telescopic member placing the workpiece on the carrier table, and through the buffer space, a buffer is achieved between the telescopic member and the fixed frame; as the output end of the telescopic member continues to contract, the distance between the contact plate and the trigger switch gradually decreases, so that the contact plate presses against the trigger point of the trigger switch to control all telescopic members to stop working in time.

[0013] Preferably, the clamping assembly includes two groups of clamping plates, a plurality of guide rods and a plurality of pushing members; one group of the clamping plates is located on one side of the collecting pipe, and the other group of the clamping plates is located on the other side of the collecting pipe, all of the guide rods are arranged on the mounting frame, and each of the guide rods passes through the two groups of clamping plates; each of the pushing members is arranged between the clamping plates and the mounting frame, and the pushing members are used to drive the two groups of clamping plates to move closer to or away from each other.

[0014] By adopting the above technical solution, the output end of the pushing member extends out, so that the two groups of clamping plates are close to each other to clamp the workpiece; the output end of the pushing member contracts, so that the two groups of clamping plates are away from each other, so that the clamping plates gradually separate from the workpiece; the guide rod limits and guides the moving direction and moving path of the clamping plate, reducing the phenomenon of dislocation or offset during the movement of the clamping plate; at the same time, the guide rod supports the clamping plate, so that the clamping plate can clamp and lift the workpiece more stably.

[0015] Preferably, the outside of the collecting pipe is slidably sleeved with a sliding sleeve, and a positioning rod is provided on the side wall of the sliding sleeve away from the supporting platform; a fixing block is provided on the outer side wall of the collecting pipe, a passage hole is penetrated through the fixing block for the positioning rod to pass through, and a fastener is provided on the positioning rod for limiting the positioning rod from being separated from the fixing block; a reset spring is sleeved on the positioning rod, one end of the reset spring is connected to the fixing block, and the other end of the reset spring is connected to the sliding sleeve; the side walls of the two clamping plates away from each other are provided with extension plates for abutting the sliding sleeve to slide along the height direction of the collecting pipe.

[0016] By adopting the above technical solution, the sliding sleeve sleeved outside the collection pipe abuts against the extension plate, reducing the gap between the clamping plate and the collection pipe, and reducing the phenomenon that the workpiece falls along the collection pipe and disengages through the gap between the collection pipe and the bearing table; in addition, the slidably connected sliding sleeve realizes the adjustability of the distance between the collection pipe and the bearing table; when the output end of the telescopic member extends, the extension plate abuts against the sliding sleeve, causing the sliding sleeve to move upward, and the return spring deforms and contracts under pressure, thereby increasing the distance between the collection pipe and the bearing table; when the output end of the telescopic member contracts, the extension plate gradually disengages from the sliding sleeve, and under the action of its own gravity and the elastic force of the return spring recovering deformation, the sliding sleeve moves towards the bearing table to make the sliding sleeve abut against the extension plate.

[0017] Preferably, the transfer assembly includes a plurality of transfer rollers, a plurality of buffer sleeves and a driving member; each transfer roller is rotatably arranged on the bearing table, the transfer rollers and the buffer sleeves are in one-to-one correspondence, each buffer sleeve is sleeved on the corresponding transfer roller, and each buffer sleeve abuts against the workpiece; the driving member is arranged on the bearing table to drive all the transfer rollers to rotate synchronously.

[0018] By adopting the above technical solution, the soft-textured buffer sleeve can absorb part of the impact force when the workpiece falls, reducing the damage caused by the falling workpiece to the structure on the bearing table; at the same time, the buffer sleeve increases the friction between the transfer roller and the workpiece, so that the rotating transfer roller can quickly transfer the workpiece; the driving member drives all the transfer rollers to rotate synchronously, so that the rotating transfer rollers can quickly transfer the workpiece.

[0019] Preferably, the driving assembly includes a plurality of driving worm wheels, a driving worm and a driving motor; the driving worm wheels and the transfer rollers are in one-to-one correspondence, each driving worm wheel is sleeved on the end of the corresponding transfer roller, and all the driving worm wheels are located on the same side of all the transfer rollers; the driving worm is rotatably connected inside the bearing table, and the driving worm meshes with each group of driving worm wheels; the driving motor is arranged on the bearing table, and the driving motor is used to drive the driving worm to rotate.

[0020] By adopting the above technical solution, the output end of the driving motor drives the driving worm to rotate, and the driving worm drives all the transfer rollers to rotate synchronously through meshing transmission with multiple groups of driving worm wheels, so as to realize that one motor drives all the transfer rollers to rotate, reducing the installation quantity and installation requirements of the motors and reducing the processing cost of the overall device.

[0021] Preferably, two sets of guide plates are provided between the carrier table and the conveyor. One set of the guide plates is located on one side of the conveyor in the width direction, and the other guide plate is located on the other side of the conveyor in the width direction. A plurality of sets of guide rollers are rotatably provided on each guide plate.

[0022] By adopting the above technical solution, when the workpiece moves onto the conveyor through the transfer roller, the workpiece abuts against the guide plate, so as to stably and accurately guide the workpiece on the carrier table onto the conveyor for transportation, thereby reducing the occurrence of the phenomenon that the workpiece detaches from the conveyor; at the same time, the rotating guide rollers reduce the friction between the workpiece and the guide plate, facilitating the rapid transfer of the workpiece.

[0023] Preferably, a plurality of sets of fixing rods are provided on the carrier table, and a sliding ring is slidably provided on each fixing rod; two sets of elastic members are sleeved on each fixing rod, and each sliding ring is located between the corresponding two sets of elastic members; the end portions of the two sets of elastic members on the same fixing rod that are far away from each other are connected to the carrier table, and the end portions of the two sets of elastic members on the same fixing rod that are close to each other are connected to the corresponding sliding ring.

[0024] By adopting the above technical solution, when the workpiece drops onto the carrier table, part of the impact force of the carrier table is transmitted to the sliding ring, causing the sliding ring to slide along the fixing rod. At the same time, the elastic member connected to the sliding ring deforms and contracts, converting the kinetic energy of the sliding block into the elastic potential energy of the elastic member, thereby reducing the damage caused to the carrier table by the impact of the workpiece.

[0025] Preferably, a plurality of sets of rotating shafts are rotatably provided on the inner side wall of the collection pipe, and all the rotating shafts are relatively distributed on both sides of the central axis of the collection pipe; a buffer plate is provided on each rotating shaft, and a torsion spring for driving the buffer plate to rotate in a direction away from the carrier table is provided on each rotating shaft.

[0026] By adopting the above technical solution, when the workpiece drops along the collection pipe, the workpiece impacts the buffer plate, driving the buffer plate to rotate and causing the torsion spring to undergo elastic deformation, converting part of the kinetic energy of the workpiece into the elastic potential energy of the torsion spring, thereby reducing the falling speed of the workpiece and reducing the damage caused by the falling workpiece colliding with the carrier table.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a collection pipe, the fallen workpieces are stacked on the carrier, so that the workpieces can be quickly collected; by setting up a control mechanism, a single workpiece is retained on the carrier, so that the transfer component can sequentially transfer the single workpiece to the next assembly line through the conveyor, thereby reducing the labor loss of manually collecting and transferring the workpieces;

[0029] 2. By setting a trigger switch and a contact plate, the telescopic part stops working in time when the telescopic part and the clamping assembly cooperate with each other to place the workpiece on the load-bearing table; by reserving a buffer space between the trigger switch and the contact plate, the phenomenon that the telescopic part fails to close in time when the workpiece is placed on the load-bearing table, resulting in damage to the connection between the telescopic part and the mounting frame, is reduced, thereby ensuring the service life of the control mechanism.

[0038] The following will Figures 1-6 further elaborate on this application in conjunction with the attached drawings.

[0039] The embodiment of this application discloses a steel plate stamping device, which is used to quickly collect the workpieces after the steel plate is stamped and formed, and sequentially transfer the workpieces to the next production line of the workpieces.

[0040] Refer to Figure 1 and Figure 2 A steel plate stamping device includes a workbench 1 placed on the ground and a stamping machine 11 placed on the workbench 1; a punching hole 12 is vertically penetrated through the workbench 1 for the workpieces separated from the stamping of the steel plate to pass through the punching hole 12 and fall below the workbench 1. A collection pipe 2 is welded and fixed around the punching hole 12 at the bottom of the workbench 1, and a carrying platform 3 is placed on the ground at the bottom of the workbench 1. The carrying platform 3 is located below the collection pipe 2 to facilitate the carrying platform 3 to carry the workpieces falling from the workbench 1. A conveying member 4 is placed on the ground on one side of the carrying platform 3. In this embodiment, the conveying member 4 is a roller conveyor, which is used to transfer the workpieces to the next production line of the workpieces. A control mechanism 5 is installed between the carrying platform 3 and the collection pipe 2 to retain a single workpiece on the carrying platform 3; a transfer assembly 6 is installed on the carrying platform 3 to transfer the workpieces on the carrying platform 3 to the conveying member 4.

[0041] Refer to Figure 1 and Figure 2, several groups of rotating shafts 23 are rotatably connected to the inner sidewall of the collection pipe 2, and all the rotating shafts 23 are symmetrically distributed on both sides of the central axis of the collection pipe 2. A buffer plate 231 is welded and fixed to each rotating shaft 23. In this embodiment, the buffer plate 231 can be made of tough plastic or rubber. A torsion spring 232 is sleeved on the end of each rotating shaft 23. One end of the torsion spring 232 in the length direction is adhesively fixed to the inner sidewall of the collection pipe 2, and the other end of the torsion spring 232 is adhesively fixed to the buffer plate 231.

[0042] Refer to Figure 1 and Figure 2 , the torsion spring 232 exerts a force on the buffer plate 231 to rotate in a direction away from the bearing platform 3. At the same time, due to the self-gravity of the buffer plate 231, the buffer plate 231 is urged to rotate in a direction close to the bearing platform 3, so that the buffer plate 231 tends to be parallel to the horizontal plane.

[0043] Refer to Figure 1 and Figure 2 , when the workpiece falls into the interior of the collection pipe 2 from the punching hole 12, the workpiece collides with the buffer plate 231, and the impact force received by the buffer plate 231 gradually rotates in a direction close to the bearing platform 3. By the rotation of the buffer plate 231, the distance between the opposite buffer plates 231 is increased, so as to facilitate the workpiece to pass through the space between the opposite buffer plates 231. At the same time, the buffer plate 231 also slows down the falling speed of the workpiece.

[0044] Refer to Figure 2 and Figure 3 , the control mechanism 5 includes a mounting frame 51, a telescopic member 52 and a clamping assembly 53 for clamping the workpiece. In this embodiment, the telescopic member 52 is a telescopic oil cylinder. The telescopic member 52 is fixedly installed on the ground around the bearing platform 3, and the length direction of the telescopic member 52 is parallel to the height direction of the bearing platform 3. The mounting frame 51 is placed on the output ends of all the telescopic members 52, and the mounting frame 51 is located between the bearing platform 3 and the collection pipe 2. When the output end of the telescopic member 52 expands and contracts, it can drive the mounting frame 51 to move along the height direction of the bearing platform 3.

[0045] Refer to Figure 4 and Figure 5 , the output end of each telescopic member 52 is fixedly connected with a contact plate 521, and the contact plate 521 abuts against the sidewall of the mounting frame 51 facing the ground to support the mounting frame 51. A plurality of limit cylinders 511 are welded and fixed to the bottom wall of the mounting frame 51. The limit cylinders 511 correspond to the contact plates 521 one by one, and each group of contact plates 521 is located inside the corresponding limit cylinder 511.

[0046] Refer to Figure 4 and Figure 5, where a trigger switch 512 is fixedly installed inside a group of limiting cylinders 511. In this embodiment, the trigger switch 512 is electrically connected to all the telescopic members 52. By pressing the trigger point of the trigger switch 512, all the telescopic members 52 can be controlled to stop working. There is a buffer space 513 left between the contact plate 521 inside the limiting cylinder 511 where the trigger switch 512 is installed and the trigger switch 512.

[0047] Refer to Figure 4 and Figure 5 , when the output end of the telescopic member 52 contracts, making the workpiece clamped by the clamping assembly 53 gradually abut against the upper surface of the bearing table 3, the bearing table 3 supports and fixes the workpiece and the mounting frame 51. At this time, the output end of the telescopic member 52 continues to contract, the contact plate 521 and the trigger switch 512 gradually approach each other, and the buffer space 513 gradually decreases. When the contact plate 521 abuts against the trigger point of the trigger switch 512, the trigger switch 512 controls all the telescopic members 52 to stop working in time.

[0048] Refer to Figure 3 and Figure 4 , the clamping assembly 53 includes two groups of clamping plates 531, a plurality of guide rods 532 and a plurality of pushing members 533. In this embodiment, the pushing member 533 is a pushing oil cylinder. All the pushing members 533 are fixedly installed on the inner side wall of the mounting frame 51, and a part of the pushing members 533 is located on one side of the bearing table 3, and the other part of the pushing members 533 is located on the other side of the bearing table 3. One group of clamping plates 531 is fixedly connected to the output ends of all the pushing members 533 on one side of the bearing table 3, and the other group of clamping plates 531 is fixedly connected to the output ends of all the pushing members 533 on the other side of the bearing table 3. When the output end of the pushing member 533 expands and contracts, the two groups of clamping plates 531 can be controlled to approach each other to clamp the workpiece, or the two groups of clamping plates 531 can be controlled to move away from each other to release the workpiece.

[0049] Refer to Figure 3 and Figure 4 , all the guide rods 532 are welded and fixed on the inner side wall of the mounting frame 51. Each group of guide rods 532 penetrates through the two groups of clamping plates 531, and the length directions of all the guide rods 532 are parallel to the direction in which the two groups of clamping plates 531 move towards each other.

[0050] Refer to Figure 3 and Figure 4 , after the clamping assembly 53 clamps the workpiece, the output end of the telescopic member 52 extends, pushing the mounting frame 51 and the clamping assembly 53 to gradually move away from the bearing table 3, so that most of the workpieces on the bearing table 3 gradually leave the bearing table 3 following the clamping assembly 53, and only a single workpiece remains on the bearing table 3 for transfer.

[0051] Refer to Figure 2 and Figure 3, a plurality of groups of fixing blocks 22 are welded and fixed on the outer wall of the collection pipe 2, and all the fixing blocks 22 are evenly distributed along the circumference of the collection pipe 2. A through hole 221 is provided in each group of fixing blocks 22 in the vertical direction, and a positioning rod 211 is movably inserted in each group of through holes 221. A fastener 2111 is threadedly connected to one end of each group of positioning rods 211 away from the supporting platform 3. In this embodiment, the fastener 2111 is a fastening nut. The fastener 2111 is abutted against the side wall of the fixing block 22 away from the supporting platform 3 to limit the positioning rod 211 from passing through the through hole 221 and detaching from the fixing block 22.

[0052] Reference Figure 2 and Figure 3 The ends of all the positioning rods 211 away from the fasteners 2111 are welded with a sliding sleeve 21, and the sliding sleeve 21 is slidably sleeved on the outer wall of the collecting pipe 2. A return spring 2112 is sleeved on each group of positioning rods 211, one end of the return spring 2112 in the length direction is glued to the fixing block 22, and the other end of the return spring 2112 is glued to the sliding sleeve 21.

[0053] Reference Figure 2 and Figure 3 The side walls of the two groups of clamping plates 531 that are away from each other are integrally formed with extension plates 5311. When the clamping plates 531 follow the mounting frame 51 to move toward the direction close to the collection pipe 2, the extension plates 5311 abut against the bottom wall of the sliding sleeve 21 to push the sliding sleeve 21 to slide along the length direction of the collection pipe 2 toward the direction away from the supporting platform 3.

[0054] Reference Figure 2 and Figure 6 The transfer assembly 6 includes a plurality of transfer rollers 61, a plurality of buffer sleeves 62 and a driving member 63. In this embodiment, the buffer sleeve 62 can be made of soft rubber. All the rotating rollers are rotatably mounted on the support platform 3 through the end shaft 611 at the end of the rotating roller, and all the rotating rollers are parallel to each other. The buffer sleeves 62 correspond to the transfer rollers 61 one by one, and each group of buffer sleeves 62 is fixedly sleeved on the corresponding transfer rollers 61. The buffer sleeve 62 abuts against the workpiece, so that the transfer roller 61 can transport the workpiece.

[0055] Reference Figure 2 and Figure 6, an installation cavity 301 is provided inside the carrier table 3, the driving member 63 is located inside the installation cavity 301, and the driving member 63 includes a number of groups of driving worm wheels 631, driving worm shafts 632 and driving motors 633. The driving worm wheels 631 and the transfer rollers 61 correspond to each other one by one. The end shafts 611 on the same side of all the transfer rollers 61 extend into the installation cavity 301. Each group of driving worm wheels 631 is fixedly sleeved on the end shaft 611 at the end of the corresponding transfer roller 61, and all the driving worm wheels 631 are located inside the installation cavity 301.

[0056] Refer to Figure 2 and Figure 6 , the driving worm shaft 632 is rotatably installed on the inner side wall of the installation cavity 301, and the driving worm shaft 632 meshes with all the driving worm wheels 631. The driving motor 633 is fixedly installed on the outer side wall of the carrier table 3, and the output end of the driving motor 633 is in transmission connection with the driving worm shaft 632.

[0057] Refer to Figure 2 and Figure 6 , when the output end of the driving motor 633 rotates, it drives the driving worm shaft 632 to rotate. The rotating driving worm shaft 632 meshes and drives with the driving worm wheels 631, so that all the transfer rollers 61 rotate synchronously, thereby realizing the transfer of the workpiece on the carrier table 3.

[0058] Refer to Figure 2 , a transition plate 41 is fixedly welded between the carrier table 3 and the conveying member 4. Two groups of guide plates 31 are fixedly welded on the upper surface of the carrier table 3. One group of guide plates 31 is located on one side in the width direction of the transition plate 41, and the other group of guide plates 31 is located on the other side in the width direction of the transition plate 41. One end of each group of guide plates 31 away from the carrier table 3 is fixedly welded to the conveying member 4. The distance between the two groups of guide plates 31 gradually decreases in the direction close to the conveying member 4. A number of groups of guide rollers 311 are rotatably connected to each group of guide plates 31 to facilitate guiding the workpiece on the carrier table 3 onto the conveying member 4.

[0059] Refer to Figure 2 and Figure 6 , an installation notch 302 is provided on the peripheral wall of the carrier table 3, and a number of groups of fixing rods 32 are fixedly welded inside the installation notch 302. All the fixing rods 32 are distributed at intervals along the circumference of the carrier table 3. Two groups of elastic members 322 are sleeved on each group of fixing rods 32. In this embodiment, the elastic members 322 are springs. A sliding ring 321 is also movably sleeved on each group of fixing rods 32, and the sliding ring 321 is located between the two groups of elastic members 322 on the corresponding fixing rod 32.

[0060] Refer to Figure 2 and Figure 6, at the mutually remote ends of the two sets of elastic members 322 on each fixed rod 32, they are adhesively connected to the inner side walls of the mounting notches 302, and at the mutually close ends of the two sets of elastic members 322, they are adhesively connected to the sliding ring 321. When the bearing platform 3 is impacted by the workpiece, the sliding ring 321 can slide along the length direction of the fixed rod 32, and drive the elastic members 322 to undergo elastic deformation, thereby absorbing the impact force received by the bearing platform 3.

[0061] The implementation principle of an iron plate stamping device according to an embodiment of the present application is as follows:

[0062] The iron plate is placed on the workbench 1, and the iron plate is stamped by the stamping machine 11. The stamped workpiece is separated from the iron plate and falls into the collection pipe 2 through the punching hole 12. The collection pipe 2 collects and gathers the workpieces, so that the workpieces fall and stack on the bearing platform 3.

[0063] Control the clamping assembly 53 to clamp the workpiece, and then control the output end of the telescopic member 52 to extend, so that the mounting bracket 51 and the clamping assembly 53 gradually move away from the bearing platform 3, so that only a single workpiece remains on the bearing platform 3; then start the driving motor 633, and transfer the single workpiece on the bearing platform 3 to the conveying member 4 through the transfer roller 61, so as to collect the workpiece and sequentially transfer the workpiece to the next production line of the workpiece.

[0064] After the single workpiece on the bearing platform 3 is transferred, control the output end of the telescopic member 52 to contract. When the workpiece on the clamping assembly 53 abuts against the upper surface of the bearing platform 3, control the clamping assembly 53 to gradually disengage from the workpiece; then, control the output end of the telescopic member 52 to extend, and control the clamping assembly 53 to re-clamp the workpiece, so as to place a new single workpiece on the bearing platform 3 for waiting to be transferred.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
