[0051] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] During the sheet metal production process, after the sheet metal is processed by a stamping machine or other processing equipment and discharged as a finished product, it needs to be transported to a stacking device for stacking and transfer. Due to limitations of the environment, the operating equipment, the stacking equipment structure itself, or other factors, the stacking equipment's inlet and outlet are located at the same height or have a small height difference, making it impossible to feed the stacking equipment from above. Therefore, the workpiece needs to be raised to a certain height before it can be fed smoothly. The stacking production line of this embodiment can solve the problem of workpiece feeding and stacking in this situation.

[0053] like Figure 1-18 FIG. 1 is a schematic diagram of an embodiment of a stacking production line provided by the present invention.

[0054] Please refer to Figure 1-18 This embodiment is used to realize the feeding and stacking of products after the operating equipment discharges the materials. Figure 1 As shown, this embodiment includes a workpiece transfer device 10, a frame 100, a feeding assembly 200, a flapping assembly 300 and a material receiving assembly 400. The workpiece transfer device 10, the feeding assembly 200, and the flapping assembly 300 are arranged on the frame 100, and the material receiving assembly 400 is arranged below the outlet of the flapping assembly 300.

[0055] The workpiece transfer device 10 transfers the workpiece from a first position to a second position along a first direction. The feeding assembly 200 picks up the workpiece at the second position and moves along the second direction to a third position. At the third position, the feeding assembly 200 unloads the workpiece to the beating assembly 300. The beating assembly 300 beats the workpiece and then unloads it to the receiving assembly 400, which collects the workpieces to form a stack.

[0056] In this embodiment, the first direction may be specifically the z-direction perpendicular to the horizontal plane, the second direction may be specifically the horizontal x-direction, the second position is higher than the first position, the second position and the third position are at the same height, the receiving assembly 400 is located below the third position, and the first position may be specifically the discharge position of the operating device 500. The workpiece transfer device 10 is used to lift the workpiece discharged from the operating device 500 vertically to a certain height to the feeding assembly 200. The feeding assembly 200 moves the workpiece horizontally a certain distance to the beating assembly 300. The beating assembly 300 beats the workpiece for centering and then unloads the workpiece. The workpiece is fed into the inlet above the receiving assembly 400.

[0057] In one embodiment, if Figure 2-9As shown, the workpiece transfer device 10 includes a support frame 110, a synchronization assembly 120, a power assembly 130, a telescopic assembly 140, and at least two retrieving assemblies 150. The synchronization assembly 120, the power assembly 130, the telescopic assembly 140, and the retrieving assemblies 150 are disposed on the support frame 110. The support frame 110 is used to support each assembly at a predetermined height and to connect the various assemblies. The power assembly 130 is in transmission connection with the synchronization assembly 120, and the retrieving assemblies 150 are in transmission connection with the synchronization assembly 120. At least one retrieving assemblies 150 is in transmission connection with the synchronization assembly 120 via the telescopic assembly 140. The power assembly 130 drives the two retrieving assemblies 150 to move back and forth in a first direction. The power assembly 130 drives the two retrieving assemblies 150 to move upward from a first position to a second position, and then downward from the second position to the first position, maintaining a constant frequency. When the two retrieving assemblies 150 move toward each other, the telescopic assembly 140 drives the connected retrieving assembly 150 to move in a second direction to avoid the other retrieving assembly. The telescopic assembly 140 drives the material-retrieving assembly 150 connected thereto to avoid the other material-retrieving assembly 150 along the x-direction, thereby preventing the two material-retrieving assemblies 150 from colliding and interfering with each other when moving in the z-direction.

[0058] Power assembly 130 includes a motor 131, an output shaft 132, and a driving pulley 133. Motor 131 is mounted on support frame 110. The output end of motor 131 is in driving connection with output shaft 132. Driving pulley 133 is mounted on output shaft 132 and rotates synchronously with output shaft 132. Motor 131 drives output shaft 132 and driving pulley 133 to achieve power output.

[0059] The synchronization assembly 120 includes a synchronization belt 121, a synchronization wheel 122, a first linear guide 123, and a second linear guide 124. The synchronization wheel 122 is hingedly connected to the support frame 110. The synchronization belt 121 is wound around the synchronization wheel 122 and the driving wheel 133. The power output by the motor 131 is transmitted to the synchronization wheel 122 and the synchronization belt 121, driving the synchronization belt 121. The first linear guide 123 and the second linear guide 124 are parallel to the first direction, that is, the first linear guide 123 and the second linear guide 124 are arranged vertically. The first linear guide 123 and the second linear guide 124 are arranged parallel to each other in the second direction, that is, there is a gap between them in the horizontal x-direction. The synchronization belt 121 has at least two linear sections, which respectively cover the first linear guide 123 and the second linear guide 124. The material picking assembly 150 is connected to the linear sections via a pressing block 125. The first linear guide 123 and the second linear guide 124 are each slidably connected to a material picking assembly 150.

[0060] The synchronous belt 121 drives the material taking assembly 150 to move in the vertical direction along the first linear guide rail 123 or the second linear guide rail 124. The synchronous belt 121 plays a role in power transmission, and the first linear guide rail 123 or the second linear guide rail 124 plays a guiding role.

[0061] Furthermore, there are four synchronous pulleys 122 arranged in a rectangular pattern with four corners, and the area of ​​the synchronous belt 121 between the front and rear synchronous pulleys is a straight line. A driving pulley 133 is located in the upper middle portion of the upper synchronous pulley 122. Adjusting pulleys 126 are located between the driving pulley 133 and the two synchronous pulleys on each side. The synchronous belt 122 is wound around the adjusting pulleys 126, forming an S-shape between the upper synchronous pulley 122, the driving pulley 133, and the adjusting pulleys 126. The adjusting pulleys 126 are used to adjust the tension of the synchronous belt 121.

[0062] Specifically, there are two sets of synchronous wheels 122, each containing four synchronous wheels 122. The two sets of synchronous wheels 122 are symmetrically distributed, corresponding to two synchronous belts and two driving wheels 133, all symmetrically distributed. This design connects the two sides of the movable plate of the reclaiming assembly 150, ensuring that the reclaiming assembly 150 remains stable and balanced when moving in the vertical direction.

[0063] In one embodiment, there are two retrieving assemblies, namely a first retrieving assembly 151 and a second retrieving assembly 152. The two linear sections are each connected to a retrieving assembly 150 via a pressing block 125. The first retrieving assembly 151 is slidably connected to the first linear guide 123, and the second retrieving assembly 152 is slidably connected to the second linear guide 124. The first retrieving assembly 151 is located in front of the second retrieving assembly 152.

[0064] Furthermore, the material removal assembly 150 includes a movable plate 153, a suction cup 154, and a connecting frame 155. The connecting frame 155 is used to connect the movable plate 153 and the suction cup 154. The connecting frame 155 extends a certain length in the x-direction. The suction cup 154 ​​is specifically an electromagnetic suction cup. The two sides of the movable plate 153 are slidably connected to the first linear guide rail 123 and / or the second linear guide rail 124 via sliders 156. The two sides of the movable plate 153 are fixedly connected to the linear section of the synchronous belt 121 via pressure blocks 125.

[0065] Specifically, the telescopic assembly 140 is provided on the movable plate 153 in the second picking assembly 152, and the telescopic assembly 140 is connected to the connecting frame 155 of the second picking assembly 152, that is, the telescopic assembly 140 is located between the movable plate 153 and the connecting frame 155 of the second picking assembly 152. The telescopic assembly 140 is used to drive the connecting frame 155 of the second picking assembly 152 to extend and retract along the second direction. When the suction cup 154 ​​of the second picking assembly 152 moves along the vertical direction and interferes with the suction cup of the first picking assembly 151, the telescopic assembly 140 retracts the suction cup of the second picking assembly 152 to avoid interference; when the two do not interfere, the telescopic assembly 140 pushes the suction cup of the second picking assembly 152 to extend and be located in the same vertical plane as the first picking assembly 151, so as to facilitate picking and unloading. The following is a detailed description:

[0066] When the first picking assembly 151 moves in the first direction (upward or downward) to the middle of the first linear guide 123, the telescopic assembly 140 drives the connecting frame of the second picking assembly 152 in the second direction (backward) away from the first picking assembly 151, preventing interference and collision between the two and achieving alternating movement. When the first picking assembly 151 moves in the first direction (upward or downward) to the upper or lower side of the first linear guide 123, the telescopic assembly 140 drives the connecting frame of the second picking assembly 152 in the second direction (forward) closer to the first picking assembly 151, and the suction cup of the second picking assembly 142 is directly above or below the suction cup of the first picking assembly 141.

[0067] The telescopic assembly 140 includes a guide plate 141, a guide rod 142, a cam 143, a lifting shaft 144, a telescopic plate 145, and a scissor-type telescopic rod 146. The guide plate 141 is mounted on the support frame 110 and is provided with a guide slot 1411. The upper and lower portions of the guide slot 1411 are linear, while the middle portion is concave and curved in the second direction (rearward) away from the first retrieving assembly 151. The guide rod 142 and lifting shaft 144 are mounted parallel to the second direction on the movable plate of the second retrieving assembly 152 and can extend and retract through the movable plate 153. One end of the lifting shaft 144 is hinged to the cam 143, and the other end is connected to the telescopic plate 145. The cam 143 is mounted in the guide slot 1411 and rolls along the guide slot 1411. The scissor-type telescopic rod 146 is composed of two crossed rods, the middle part of the crossed rod is hinged to the telescopic plate 145, one end of the crossed rod of the scissor-type telescopic rod 146 is hinged to the movable plate 153 of the second material-taking assembly 152 through the connecting rod 147, and the other end is hinged to the connecting frame 155 of the second material-taking assembly 152.

[0068] There are multiple guide plates 141, specifically three in this embodiment. The three guide plates 141 are arranged in parallel, and the corresponding guide grooves 1411 of the guide plates 141 are also arranged in parallel. Correspondingly, there are three lifting shafts 144 and three cams 143. The guide grooves 1411 of the guide plates 141 control the opening and closing frequency of the scissor-type telescopic rod 146, and thus the movement frequency of the second material removal assembly 152 in the second direction.

[0069] Specifically, when the movable plate 153 of the second material removal assembly 152 moves along the second linear guide rail 124, the cam 143 rolls along the guide groove 1411, driving the lifting shaft 144 to telescopically move in the second direction. The telescopic movement of the lifting shaft 144 drives the scissor-type telescopic rod 146 to open or close. The specific process of opening and closing the scissor-type telescopic rod 146 is as follows:

[0070] As the movable plate 153 of the second picking assembly 152 moves to the upper or lower side of the second linear guide rail 124, the cam 143 moves from the curved position in the guide groove 1411 to a linear position. The lifting shaft 144 approaches the first picking assembly 151 in the second direction. The lifting shaft 144 pushes the telescopic plate 145, causing the scissor-type telescopic rod 146 to open. The suction cup 154 ​​of the second picking assembly 152 is located directly above or below the suction cup of the first picking assembly 151. Directly below is the picking position, and directly above is the unloading position.

[0071] When the movable plate 153 of the second material picking component 152 moves to the middle of the second linear guide rail 124, the cam 143 moves from the linear position of the guide groove 1411 to the curved position, and the lifting shaft 144 moves away from the first material picking component 151 along the second direction. The lifting shaft 144 pulls the telescopic plate 145 to make the scissor-type telescopic rod 146 closed. The suction cup 154 ​​of the second material picking component 152 is projected in the first direction and the suction cup 154 ​​of the first material picking component 151 is projected in the first direction without overlapping, thereby realizing the alternation of the first material picking component 151 and the second material picking component 152 when they move up and down.

[0072] In one embodiment, if Figure 10-14 As shown, the feeding assembly 200 includes a magnetic track 210, a push plate 220, and a push cylinder 230. The magnetic track 210 is mounted on the frame 100. A push cylinder 230 is positioned at the unloading position of the magnetic track 210. The movable end of the push cylinder 230 is connected to the push plate 220, which is positioned opposite the inlet of the flapping assembly 300. The magnetic track 210 transports the workpiece from the second position to the third position. The push plate 220 pushes the workpiece away from the magnetic track 210, achieving auxiliary unloading.

[0073] In one embodiment, the magnetic track 210 includes a bracket 211, and the two ends of the bracket 211 are respectively hinged to the output wheel 212 and the driven wheel 213. A conveyor belt 214 is wound between the output wheel 212 and the driven wheel 213, and the bracket 211 is provided with a motor 215, which is in transmission connection with the output wheel 212. The conveyor belt 214 between the output wheel 212 and the driven wheel 213 is a conveying interval. The rotation of the motor 215 drives the output wheel 212 to rotate, thereby driving the conveyor belt 214 and the driven wheel 213 to rotate. A plurality of evenly distributed permanent magnets 126 are provided inside the bracket 211. The permanent magnet 216 is provided on one side of the bracket 211. The conveyor belt 214 on the surface of this side contacts the workpiece, and the workpiece is adsorbed on the surface of the conveyor belt 214 through the permanent magnet 216. The rotation of the conveyor belt 214 drives the workpiece to move in the horizontal direction. The bracket 211 is provided with a unloading position, and an electromagnet 217 is provided inside the bracket 211 corresponding to the unloading position. The electromagnet 217 is fixed inside the bracket 211. The unloading of the workpiece moved to the unloading position is controlled by the on-off control of the electromagnet 217. When the workpiece moves to the unloading position, the electromagnet 217 is disconnected and the magnetic force disappears. The workpiece is separated from the conveyor belt 214 under the action of gravity to realize unloading.

[0074] Furthermore, there are at least two brackets 211, with adjacent brackets 211 symmetrically and aligned, with a predetermined spacing between them. Adjacent brackets 211 are connected by connecting rods 218, and the output wheels 212 of adjacent brackets 211 are connected by connecting shafts 219. This design can expand the conveying width and ensure the stability of conveying workpieces. A pusher cylinder 230 and a pusher plate 220 are located within the spacing between adjacent brackets 211.

[0075] In one embodiment, if Figure 15-17 As shown, the flapping assembly 300 includes a material receiving chamber 310, with an inlet on the upper side and an outlet on the lower side. The inlet is aligned with the unloading position of the feeding assembly 200. The left and right sides of the material receiving chamber 310 are respectively provided with flapping members 320 for flapping and centering the left and right sides of the workpiece. The front or rear side of the material receiving chamber 310 is provided with a flapping member 320 for flapping and centering the front or rear side of the workpiece.

[0076] Furthermore, the flapping member 320 includes a flapping plate 321 and a flapping cylinder 322. The flapping cylinder 322 is disposed in the material receiving chamber 310. The flapping plate 321 is located inside the material receiving chamber 310, and the telescopic end of the flapping cylinder 322 is connected to the flapping plate 321. The flapping plates 321 on the left and right sides of the material receiving chamber 310 are arranged opposite each other, and the flapping plates 321 on the front or rear side of the material receiving chamber 310 are arranged opposite each other to the rear side wall or front side wall of the material receiving chamber, and the rear side wall or front side wall of the material receiving chamber serves as a fixed surface. In this embodiment, the flapping cylinder 322 and flapping plate 321 are respectively provided on the left, right, and front sides of the material receiving chamber 310, and the rear side wall of the material receiving chamber 310 serves as a fixed surface. The flapping cylinder 322 pushes the flapping plate 321 to move inward from the material receiving chamber 310 to contact the workpiece to achieve flapping alignment.

[0077] The flapping members 320 on the left and right sides of the receiving chamber 310 are connected to the receiving chamber 310 via adjustment screws 330. The flapping members 320 on the left and right sides of the receiving chamber 310 are located inside the receiving chamber 310. The adjustment screws 330 adjust the relative distance between the flapping members 320 on the left and right sides of the receiving chamber 310. The flapping plates 321 and flapping cylinders 322 on the left and right sides of the receiving chamber 310 are both located within the receiving chamber 310. Due to the travel limit of the flapping cylinders 322, the adjustment screws 330 can be used to adjust the spacing between the left and right flapping members 320 to accommodate the flapping of smaller workpieces.

[0078] The outlet of the receiving chamber 310 is equipped with a receiving rod 311 and a receiving cylinder 312. The receiving cylinder 312 is located on the exterior of the front and rear sides of the receiving chamber 310 and is in transmission connection with the receiving rod 311. The receiving cylinder 312 pushes the receiving rod 311 into the receiving chamber 310, or drives the receiving rod 311 out of the receiving chamber 310. The receiving cylinder 312 pushes the receiving rod 311 into the receiving chamber 310, where it forms a barrier at the outlet of the receiving chamber 310, temporarily supporting the workpiece. After the workpiece lands on the receiving rod 311 and stabilizes, it is tapped and aligned to ensure effective tapping and alignment.

[0079] Furthermore, a correction assembly 340 is provided at the entrance of the receiving chamber 310. The correction assemblies 340 are located on either side of the receiving chamber 310, above the flapping member 320. The correction assembly 340 includes a correction cylinder 341 and a correction plate 342. The correction cylinder 341 is located within the receiving chamber 310, and the telescopic end of the correction cylinder 341 is connected to the correction plate 342. The correction cylinder 341 pushes the correction plate 342 to correct the workpiece's deviation, forcing it to fall into the flapping space defined by the flapping member 320. This prevents any positional discrepancy between the workpiece and the flapping space, which could cause the workpiece to slip and damage the flapping member.

[0080] In one embodiment, if Figure 18As shown, the material receiving assembly 400 includes a receiving frame 410 and a receiving plate 420. The receiving frame 410 is provided with multiple receiving spaces, each of which is surrounded by a plurality of vertical bars. The receiving plate 420 is moved in a first direction within the receiving spaces by a lifting cylinder 430, and is aligned with the outlet of the beating assembly 300. The receiving plate 420 is moved by the lifting cylinder 430 to the inlet of the receiving space to support the unloading of the beating assembly 300. The receiving plate 420 gradually moves downward as the thickness of the workpieces accumulates.

[0081] Furthermore, there are multiple receiving racks 410, and the multiple receiving racks 410 are moved along the third direction to below the exit of the flapping assembly 300 via the first conveying rail 440. The first conveying rail 440 allows the multiple receiving racks 410 to be rotated. The receiving racks 410 are moved along the second direction via the second conveying rail 450, so that the receiving space is aligned with the exit of the flapping assembly 300. The second conveying rail 450 allows the multiple receiving spaces in a single receiving rack 410 to be rotated. The third direction is specifically the horizontal y-direction, which is perpendicular to the second x-direction.
