[0002] Fine stamping, through its unique die structure design, produces parts with high dimensional accuracy and good cross-sectional quality, and is widely used in the automotive, mechanical electronics, and aerospace industries.
[0003] Chinese Patent No. CN209737027U discloses a large-scale mechanical air conditioning compressor valve plate production device, including an automatic feeder, a fine blanking machine, a vertical grinding machine, a grinding machine, and a polishing machine. The automatic feeder is equipped with a gear roller, and the other side of the automatic feeder is connected to the fine blanking machine. The fine blanking machine is connected to the vertical grinding machine via a conveyor belt. The vertical grinding machine includes an upper grinding wheel and a lower grinding wheel. The valve plate is placed between the upper grinding wheel and the lower grinding wheel. The polishing mechanism includes a brush, and the valve plate is placed at the bottom end of the brush.
[0004] During the use of the above technology, the workpiece after fine blanking needs to be deburred by using a vertical grinder, grinding machine and polishing machine, which increases the production cost of the workpiece and has shortcomings. Summary of the Invention
[0005] To reduce production costs, this application provides an in-mold robotic precision blanking device.
[0006] The in-mold robotic precision blanking device provided in this application adopts the following technical solution: An in-mold robotic precision blanking device includes a mounting base, on which an upper template and a lower template located directly below the upper template are slidably disposed. A sheet metal slides through between the upper and lower templates. The mounting base is provided with a driving component for moving the upper template, and the lower template is provided with a deburring component for removing burrs from the workpiece. The mounting base is also provided with a conveying assembly for conveying the sheet metal and a transfer device for transferring the workpiece. The driving component includes a pressing cylinder disposed on the mounting base and electrically connected to a control system, and the upper template is disposed on the piston rod of the pressing cylinder.
[0007] By adopting the above technical solution, the conveying component transports the sheet metal between the upper and lower templates. The worker starts the pressing cylinder through the control system. The piston rod of the pressing cylinder drives the upper template to press against the lower template. At the same time, the deburring device on the lower template removes the burrs on the workpiece. Finally, the transfer device transfers the processed workpiece to the next processing position. No additional deburring device is required in this process, which simplifies the processing and helps to reduce the production cost of the workpiece.
[0008] Optionally, the deburring component includes a deburring cone ring disposed on the lower template, the deburring cone ring being used to squeeze the edge of the workpiece, the upper template having a stamping groove for shearing the sheet metal, the stamping groove being used to accommodate the workpiece, and the upper template having a demolding component for separating the workpiece.
[0009] By adopting the above technical solution, when the upper template is pressed against the lower template, the deburring cone ring will squeeze the edge of the workpiece. Depending on the cross-section of the deburring cone ring, the edge of the workpiece can be chamfered or rounded to remove the burrs on the edge of the workpiece. After processing, the workpiece will be stuck in the stamping groove, and then separated from the upper template by the demolding device. This helps to simplify the processing steps of the workpiece and reduce the production cost of the workpiece.
[0010] Optionally, the upper die plate includes a stamping outer die base, and a stamping inner die base is slidably disposed on the stamping outer die base. The demolding component includes a stamping ring plate disposed on the stamping inner die base. A die groove for sliding of the stamping ring plate is provided on the stamping outer die base. A demolding spring supports the stamping ring plate and the die groove. An outer ring cylinder is provided on the stamping outer die base. The outer ring cylinder is disposed on the piston rod of the die cylinder. A demolding rod is provided on the mounting base. A demolding groove for avoiding the demolding rod is provided on the outer ring cylinder.
[0011] By adopting the above technical solution, after the workpiece is stamped, the control system controls the die cylinder to retract the piston rod. The piston rod of the die cylinder drives the outer die seat to rise through the outer ring cylinder. The inner die seat rises synchronously under the support of the demolding spring. The workpiece is stuck in the stamping groove until the inner die seat abuts against the ejector rod. As the outer die seat continues to rise, the inner die seat is pushed by the demolding spring through the stamping ring plate under the obstruction of the ejector rod. The demolding spring is compressed under force until the workpiece is ejected from the stamping groove. At the same time, the conveying component continuously conveys the sheet metal, and the workpiece falls onto the sheet metal, reducing the possibility of the workpiece falling outside the sheet metal, which facilitates the subsequent transfer device.
[0012] Optionally, the bottom of the stamping inner die base is provided with a punching rod, the lower die plate has a vertically opened residual material groove for the punching rod to slide, the mounting base is provided with a buffer ring seat, the lower die plate is slidably mounted on the buffer ring seat, a buffer compression spring is supported between the lower die plate and the mounting base, the bottom of the mounting base is provided with a collection box, and the mounting base has a receiving groove communicating with the residual material groove.
[0013] By adopting the above technical solution, when the upper template presses down on the lower template, the buffer spring contracts under force, and the punching rod punches out the center hole of the workpiece on the plate. The punched-off plate material falls from the material groove on the lower template into the collection box, reducing the possibility of the deburring cone ring on the lower template being damaged by direct impact.
[0014] Optionally, the conveying assembly includes a conveying frame mounted on a mounting base, on which a plurality of conveying rollers are rotatably mounted. The plurality of conveying rollers are arranged along the conveying direction of the plate. A drive motor electrically connected to the control system is mounted on the conveying frame, and the output shaft of the drive motor is coaxially mounted on one of the conveying rollers.
[0015] By adopting the above technical solution, during the process after the upper template presses against the lower template and separates, the control system starts the drive motor. The drive motor drives the sheet metal to be conveyed on the conveyor frame through the conveyor roller, so that the detached workpiece can fall onto the sheet metal, which is beneficial to the continuous pressing of the sheet metal and at the same time reduces the possibility of the workpiece falling off the sheet metal.
[0016] Optionally, the transfer device includes a transfer seat disposed next to the mounting base, a fixed plate slidably and rotatably disposed on the transfer seat, a plurality of clamping cylinders disposed on the fixed plate, the plurality of clamping cylinders being electrically connected to the control system, the clamping cylinders being used to clamp the workpiece, and a transfer assembly for driving the fixed plate to transfer the workpiece being disposed on the transfer seat.
[0017] By adopting the above technical solution, after the workpiece falls onto the plate, the transfer component drives the fixing plate to approach the workpiece on the plate, and the control system activates multiple clamping cylinders on the fixing plate to fix the workpiece on the plate, thereby realizing the transfer of the workpiece.
[0018] Optionally, the transfer assembly includes a rotating cylinder rotatably mounted on a transfer seat, a lifting cylinder electrically connected to a control system on the rotating cylinder, a mounting plate on the piston rod of the lifting cylinder, a fixed plate slidably mounted on the mounting plate, a pushing cylinder electrically connected to a control system on the mounting plate, the fixed plate mounted on the piston rod of the pushing cylinder, and a rotating component for driving the rotating cylinder to rotate on the transfer seat.
[0019] By adopting the above technical solution, after the rotating component drives the rotating cylinder to rotate at a certain angle, the control system starts the push cylinder to push the fixed plate close to the plate until the clamping cylinder on the fixed plate is between the upper and lower templates. The control system then starts the lifting cylinder, which controls the mounting plate to descend a certain height. After that, the clamping cylinder clamps the workpiece on the plate. Then, the lifting cylinder controls the mounting plate to rise a certain height, and the control system starts the push cylinder to move the fixed plate away from the plate. Finally, the rotating component drives the rotating cylinder to rotate and reset, thus realizing the process of transferring the workpiece on the plate.
[0020] Optionally, the rotating component includes a rotating cylinder rotatably mounted on a transfer seat and electrically connected to a control system. The rotating cylinder is circumferentially inclined relative to the axis of the rotating cylinder. The piston rod of the rotating cylinder is hinged to the rotating cylinder. The rotating cylinder has a rotating groove to avoid the rotating cylinder.
[0021] By adopting the above technical solution, the control system starts the rotating cylinder, which pushes the rotating cylinder to rotate forward and backward by extending and retracting its piston rod, so that the rotating cylinder rotates around its rotation center, thereby realizing the transfer of the workpiece. The rotating cylinder can conveniently and accurately control the rotation angle of the rotating cylinder.
[0022] Optionally, a cleaning cylinder is provided next to the transfer seat, and the cleaning cylinder contains a cleaning solution for cleaning oil stains on the surface of the workpiece.
[0023] By adopting the above technical solution, after the rotating cylinder drives the rotating drum to reset, the control system starts the clamping cylinder to release the clamping action on the workpiece, and the workpiece falls into the cleaning cylinder, where the cleaning liquid cleans the surface of the workpiece.
[0024] Optionally, the mounting plate is provided with a pickup cylinder electrically connected to the control system, and the piston rod of the pickup cylinder is provided with an electromagnet electrically connected to the control system. The electromagnet is used to attract the workpiece falling into the cleaning cylinder. A conveyor belt is provided next to the transfer seat, and the conveyor belt is used to transport the workpiece attracted by the electromagnet.
[0025] By adopting the above technical solution, when the rotating cylinder drives the rotating drum to rotate again, the pickup cylinder on the mounting plate rotates to the top of the cleaning drum. The control system starts the pickup cylinder, and the piston rod of the pickup cylinder drives the electromagnet to be immersed in the cleaning drum. At the same time, the control system energizes the electromagnet, and the electromagnet attracts the workpiece in the cleaning drum. Then, the control system controls the pickup cylinder to retract the piston rod. After that, as the rotating drum resets, the pickup cylinder rotates to the top of the conveyor belt. The control system stops energizing the electromagnet, and the workpiece falls onto the conveyor belt. The workpiece is then transported to the packaging area by the conveyor belt.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying assembly transports the sheet metal between the upper and lower templates. The worker starts the pressing cylinder through the control system. The piston rod of the pressing cylinder drives the upper template to press against the lower template. At the same time, the deburring device on the lower template removes the burrs on the workpiece. Finally, the transfer device transfers the processed workpiece to the next processing position. No additional deburring device is required in this process, which simplifies the processing and helps to reduce the production cost of the workpiece. 2. During the process of the upper template pressing down on the lower template, the deburring cone ring will squeeze the edge of the workpiece. Depending on the cross-section of the deburring cone ring, the edge of the workpiece can be chamfered or rounded to remove the burrs on the edge of the workpiece. After processing, the workpiece will be stuck in the stamping groove, and then the demolding device will separate the workpiece from the upper template, which helps to simplify the processing steps of the workpiece and reduce the production cost of the workpiece. 3. When the rotating cylinder drives the rotating drum to rotate again, the pickup cylinder on the mounting plate rotates to the top of the cleaning drum. The control system starts the pickup cylinder, and the piston rod of the pickup cylinder drives the electromagnet to be immersed in the cleaning drum. At the same time, the control system energizes the electromagnet, which attracts the workpiece in the cleaning drum. Then, the control system controls the pickup cylinder to retract the piston rod. After that, as the rotating drum resets, the pickup cylinder rotates to the top of the conveyor belt. The control system stops energizing the electromagnet, and the workpiece falls onto the conveyor belt. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0035] This application discloses an in-mold robotic precision punching device.
[0036] Reference Figure 1 An in-mold robotic precision stamping device includes a mounting base 1. An upper template 2 and a lower template 3 located directly below the upper template 2 are vertically slidably arranged on the mounting base 1. A sheet metal 01 slides between the upper template 2 and the lower template 3. The upper template 2 includes a stamping outer mold base 201. A stamping inner mold base 202 is coaxially slidably arranged inside the stamping outer mold base 201. A punching rod 8 is coaxially and integrally formed at the bottom of the stamping inner mold base 202. A residual material groove 9 is vertically opened on the lower template 3 for the punching rod 8 to slide.
[0037] Reference Figure 1 , Figure 2 and Figure 3 The diameter of the waste material slot 9 gradually increases from top to bottom. A buffer ring seat 10 is welded on the mounting base 1. The lower template 3 is vertically slidably arranged on the buffer ring seat 10. A convex ring 18 is coaxially and integrally formed on the inner side wall of the buffer ring seat 10. A buffer compression spring 11 supports the lower template 3 and the mounting base 1. A collection box 12 is arranged at the bottom of the mounting base 1. A receiving slot 13 that communicates with the waste material slot 9 is vertically opened on the mounting base 1.
[0038] Reference Figure 1 The mounting base 1 is provided with a driving component 4 for moving the upper template 2. The driving component 4 includes a molding cylinder 41 that is bolted to the top of the mounting base 1 and electrically connected to the control system. The upper template 2 is arranged on the piston rod of the molding cylinder 41.
[0039] Reference Figure 1 , Figure 3 and Figure 4 The lower template 3 is provided with a deburring component 5 for removing burrs from the workpiece 02. The deburring component 5 includes a deburring cone ring 51 integrally formed with the top of the lower template 3. The cross-section of the deburring cone ring 51 is triangular. The deburring cone ring 51 is used to squeeze the edge of the workpiece 02. The bottom of the upper template 2 is provided with a stamping groove 52 for shearing the sheet metal 01. The stamping groove 52 is used to accommodate the workpiece 02. The upper template 2 is provided with a demolding component 53 for separating the workpiece 02.
[0040] Reference Figure 1 , Figure 2 and Figure 3The demolding component 53 includes a stamping ring plate 531 integrally formed on the outer wall of the stamping inner mold base 202. The stamping outer mold base 201 has a mold groove 532 for the stamping ring plate 531 to slide. A demolding spring 533 supports the stamping ring plate 531 and the mold groove 532. An outer ring cylinder 534 is welded to the top of the outer mold base. The outer ring cylinder 534 is bolted to the piston rod of the mold cylinder 41. A demolding rod 535 is welded to the mounting base 1. A demolding groove 536 is provided on the outer ring cylinder 534 to avoid the demolding rod 535.
[0041] The worker starts the pressing cylinder 41 through the control system. The piston rod of the pressing cylinder 41 drives the outer ring cylinder 534 to descend. The outer ring cylinder 534 drives the outer stamping mold seat 201 to press onto the lower template 3. The demolding spring 533 supports the inner stamping mold seat 202 and descends synchronously with the outer stamping mold seat 201 until the punching rod 8 on the inner stamping mold seat 202 abuts against the plate 01. As the outer stamping mold seat 201 continues to descend, the plate 01 is pressed tightly against the top of the lower template 3.
[0042] As the outer stamping die 201 continues to descend, the buffer spring 11 contracts under pressure until the lower die plate 3 abuts against the protruding ring 18 on the buffer ring seat 10. The outer stamping die 201 continues to descend, and the punching rod 8 punches the sheet metal 01 out of the center hole of the workpiece 02. The excess material punched out of the sheet metal 01 falls into the collection box 12 from the excess material slot 9 on the lower die plate 3. The punching rod 8 is inserted into the excess material slot 9, and the outer stamping die 201 presses the sheet metal 01 tightly onto the lower die plate 3.
[0043] The deburring cone ring 51 on the lower template 3 and the stamping groove 52 on the stamping outer die base 201 cut the sheet metal 01 to form the workpiece 02. The workpiece 02 is stuck in the stamping groove 52, and at the same time, the edge is chamfered under the action of the deburring cone ring 51, thereby removing the burrs on the workpiece 02. Then the control system controls the die cylinder 41 to retract its piston rod. During the process, the workpiece 02 is stuck in the stamping groove 52 and rises together with the stamping outer die base 201.
[0044] Until the inner stamping die 202 abuts against the ejector rod 535, and as the outer stamping die 201 continues to rise, under the obstruction of the ejector rod 535, the inner stamping die 202 squeezes the ejector spring 533 through the stamping ring plate 531. The ejector spring 533 is compressed by force, and finally the workpiece 02 is ejected from the stamping groove 52 on the outer stamping die 201. The workpiece 02 will fall onto the sheet metal 01 that is subsequently conveyed.
[0045] Reference Figure 1 The mounting base 1 is provided with a conveying assembly 6 for conveying the plate 01. The conveying assembly 6 includes a conveying frame 61 welded to the mounting base 1. Multiple conveying rollers 62 are rotatably arranged on the conveying frame 61. The multiple conveying rollers 62 are arranged along the conveying direction of the plate 01. A drive motor 63 electrically connected to the control system is bolted to the conveying frame 61.
[0046] Reference Figure 1 , Figure 2 and Figure 3 The output shaft of the drive motor 63 is coaxially welded to one of the conveying rollers 62. A clamping rod 19 is bolted to the conveying frame 61, and a clamping wheel 20 is welded to the clamping rod 19. The clamping wheel 20 is used to press the plate 01 onto the conveying roller 62. A guide wheel cone 21 is welded to the clamping rod 19. The diameter of the guide wheel cone 21 gradually increases from the center of the axis of the conveying roller 62 towards both ends.
[0047] During the process after the upper template 2 and the lower template 3 are separated, the control system starts the drive motor 63. The drive motor 63 drives the plate 01 to be conveyed on the conveyor frame 61 at one end through the conveyor roller 62, so that the detached workpiece 02 can fall onto the plate 01.
[0048] Reference Figure 1 , Figure 5 and Figure 6 The mounting base 1 is provided with a transfer device 7 for transferring workpiece 02. The transfer device 7 includes a transfer seat 71 arranged on one side of the mounting base 1. A fixed plate 72 is slidably and rotatably arranged on the transfer seat 71. Two clamping cylinders 73 are arranged on the fixed plate 72. Both clamping cylinders 73 are electrically connected to the control system. The clamping cylinders 73 are used to clamp workpiece 02. The transfer seat 71 is provided with a transfer assembly 74 for driving the fixed plate 72 to transfer workpiece 02.
[0049] Reference Figure 1 , Figure 5 and Figure 6 The transfer assembly 74 includes a rotating cylinder 741 rotatably arranged on the transfer seat 71, a lifting cylinder 742 electrically connected to the control system and bolted to the rotating cylinder 741, a mounting plate 743 welded to the piston rod of the lifting cylinder 742, a guide post 22 welded to the mounting plate 743, a guide groove 23 for the guide post 22 to slide on the rotating cylinder 741, a fixing plate 72 slidably arranged on the mounting plate 743, and a push cylinder 744 electrically connected to the control system and bolted to the mounting plate 743.
[0050] Reference Figure 1 , Figure 5 and Figure 6 The fixed plate 72 is welded to the piston rod of the push cylinder 744. The transfer seat 71 is provided with a rotating component 745 for driving the rotating cylinder 741 to rotate. The rotating component 745 includes a rotating cylinder 7451 that is rotatably arranged on the transfer seat 71 and electrically connected to the control system. The rotating cylinder 7451 is circumferentially inclined relative to the axis of the rotating cylinder 741. The piston rod of the rotating cylinder 7451 is hinged to the rotating cylinder 741. The rotating cylinder 741 is provided with a rotating groove 7452 to avoid the rotating cylinder 7451.
[0051] Reference Figure 1 , Figure 5 and Figure 6 A cleaning cylinder 14 is arranged next to the transfer seat 71. The diameter of the cleaning cylinder 14 gradually decreases from top to bottom, so that the workpiece 02 is located at the center of the bottom of the cleaning cylinder 14. The cleaning cylinder 14 contains cleaning liquid for cleaning the oil stains on the surface of the workpiece 02. A pickup cylinder 15 electrically connected to the control system is bolted to the mounting plate 743. An electromagnet 16 electrically connected to the control system is bolted to the piston rod of the pickup cylinder 15. The electromagnet 16 is used to attract the workpiece 02 that falls into the cleaning cylinder 14. A conveyor belt 17 is arranged next to the transfer seat 71. The conveyor belt 17 is used to transport the workpiece 02 attracted by the electromagnet 16.
[0052] After the workpiece 02 falls onto the plate 01, the control system starts the rotating cylinder 7451. The rotating cylinder 7451 pushes the rotating cylinder 741 to rotate by extending its piston rod, so that the rotating cylinder 741 rotates around its rotation center and makes the fixed plate 72 face the workpiece 02. Then the control system starts the pushing cylinder 744 to push the fixed plate 72 closer to the plate 01 until the clamping cylinder 73 on the fixed plate 72 is located between the upper template 2 and the lower template 3.
[0053] Then the control system starts the lifting cylinder 742, which controls the mounting plate 743 to descend to a certain height. Then the clamping cylinder 73 clamps the workpiece 02 on the plate 01. Then the lifting cylinder 742 controls the mounting plate 743 to rise to a certain height. Then the control system starts the pushing cylinder 744 to move the fixing plate 72 away from the plate 01. Finally, the control system controls the rotating cylinder 7451 to retract its piston rod and rotate the cylinder 7451 to reset the rotating cylinder 741.
[0054] Then the control system controls the clamping cylinder 73 to release the clamping action on the workpiece 02, and the workpiece 02 falls into the cleaning cylinder 14. The cleaning liquid cleans the surface of the workpiece 02. When the control system controls the clamping cylinder 73 to fix the workpiece 02 on the plate 01 again, the picking cylinder 15 on the mounting plate 743 rotates to the top of the cleaning cylinder 14. The control system starts the picking cylinder 15, and the piston rod of the picking cylinder 15 drives the electromagnet 16 to be immersed in the cleaning cylinder 14.
[0055] Simultaneously, the control system energizes the electromagnet 16, which attracts the workpiece 02 inside the cleaning cylinder 14. Then, the control system controls the pickup cylinder 15 to retract its piston rod. Subsequently, as the rotating cylinder 7451 drives the rotating cylinder 741 to reset, the pickup cylinder 15 rotates to directly above the conveyor belt 17. The control system stops energizing the electromagnet 16, and the workpiece 02 falls onto the conveyor belt 17. The workpiece 02 will be transported to the packaging area along with the conveyor belt 17.
[0056] The implementation principle of the in-mold robotic precision stamping device in this application embodiment is as follows: The worker starts the pressing cylinder 41 through the control system. The piston rod of the pressing cylinder 41 drives the outer ring cylinder 534 to descend. The outer ring cylinder 534 drives the outer stamping mold seat 201 to press on the lower template 3. The demolding spring 533 supports the inner stamping mold seat 202 and descends synchronously with the outer stamping mold seat 201 until the punching rod 8 on the inner stamping mold seat 202 abuts against the plate 01. As the outer stamping mold seat 201 continues to descend, the plate 01 is pressed tightly against the top of the lower template 3.
[0057] As the outer stamping die 201 continues to descend, the buffer spring 11 contracts under pressure until the lower die plate 3 abuts against the protruding ring 18 on the buffer ring seat 10. The outer stamping die 201 continues to descend, and the punching rod 8 punches the sheet metal 01 out of the center hole of the workpiece 02. The excess material punched out of the sheet metal 01 falls into the collection box 12 from the excess material slot 9 on the lower die plate 3. The punching rod 8 is inserted into the excess material slot 9, and the outer stamping die 201 presses the sheet metal 01 tightly onto the lower die plate 3.
[0058] The deburring cone ring 51 on the lower template 3 and the stamping groove 52 on the stamping outer die base 201 cut the sheet metal 01 to form the workpiece 02. The workpiece 02 is stuck in the stamping groove 52, and at the same time, the edge is chamfered under the action of the deburring cone ring 51, thereby removing the burrs on the workpiece 02. Then the control system controls the die cylinder 41 to retract its piston rod. During the process, the workpiece 02 is stuck in the stamping groove 52 and rises together with the stamping outer die base 201.
[0059] Until the inner stamping die 202 abuts against the ejector rod 535, and as the outer stamping die 201 continues to rise, under the obstruction of the ejector rod 535, the inner stamping die 202 squeezes the ejector spring 533 through the stamping ring plate 531. The ejector spring 533 is compressed by force, and finally the workpiece 02 is ejected from the stamping groove 52 on the outer stamping die 201. The workpiece 02 will fall onto the sheet metal 01 that is subsequently conveyed.
[0060] During the process after the upper template 2 and the lower template 3 are separated, the control system starts the drive motor 63. The drive motor 63 drives the plate 01 to be conveyed on the conveyor frame 61 at one end through the conveyor roller 62, so that the detached workpiece 02 can fall onto the plate 01.
[0061] After the workpiece 02 falls onto the plate 01, the control system starts the rotating cylinder 7451. The rotating cylinder 7451 pushes the rotating cylinder 741 to rotate by extending its piston rod, so that the rotating cylinder 741 rotates around its rotation center and makes the fixed plate 72 face the workpiece 02. Then the control system starts the pushing cylinder 744 to push the fixed plate 72 closer to the plate 01 until the clamping cylinder 73 on the fixed plate 72 is located between the upper template 2 and the lower template 3.
[0062] Then the control system starts the lifting cylinder 742, which controls the mounting plate 743 to descend to a certain height. Then the clamping cylinder 73 clamps the workpiece 02 on the plate 01. Then the lifting cylinder 742 controls the mounting plate 743 to rise to a certain height. Then the control system starts the pushing cylinder 744 to move the fixing plate 72 away from the plate 01. Finally, the control system controls the rotating cylinder 7451 to retract its piston rod and rotate the cylinder 7451 to reset the rotating cylinder 741.
[0063] Then the control system controls the clamping cylinder 73 to release the clamping action on the workpiece 02, and the workpiece 02 falls into the cleaning cylinder 14. The cleaning liquid cleans the surface of the workpiece 02. When the control system controls the clamping cylinder 73 to fix the workpiece 02 on the plate 01 again, the picking cylinder 15 on the mounting plate 743 rotates to the top of the cleaning cylinder 14. The control system starts the picking cylinder 15, and the piston rod of the picking cylinder 15 drives the electromagnet 16 to be immersed in the cleaning cylinder 14.
[0064] Simultaneously, the control system energizes the electromagnet 16, which attracts the workpiece 02 inside the cleaning cylinder 14. Then, the control system controls the pickup cylinder 15 to retract its piston rod. Subsequently, as the rotating cylinder 7451 drives the rotating cylinder 741 to reset, the pickup cylinder 15 rotates to directly above the conveyor belt 17. The control system stops energizing the electromagnet 16, and the workpiece 02 falls onto the conveyor belt 17. The workpiece 02 will be transported to the packaging area along with the conveyor belt 17.
[0065] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
