[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0050] Example 1

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 As shown, in the technical solution, the Y direction is the front-to-back direction, the X direction is the left-to-right direction, and the Z direction is the up-down direction. A double-station punching stacking device includes two feeding units 1, two stacking tooling units 2, two stacking units 5, a heating unit 6, and a pressing unit 7 arranged in parallel with the heating unit 6 in the Y direction.

[0055] A stacking process of a double-station punching sheet stacking device in the present technical solution is as follows: 1. A worker places a stack of punching sheets on a hollow rotating platform in a feeding unit 1; 2. Module 1 201 moves forward, and a worker places a stacking tool on a transfer base plate 1 202, and module 1 201 drives the stacking tool to move backward to a predetermined position; 3. A four-axis manipulator 502 moves to the hollow rotating platform to absorb the punching sheets, and stacks them on the stacking tool at the stacking tool unit 2 until a predetermined number of punching sheets are stacked; 4. The stacked products are placed on a transfer base plate 2 719, Module four 720 moves backward to transport the stacked product to the heating coil 605 for heating and curing. 5. After the product is heated and cured, module four 720 moves forward to drive the product to move under the pressure head 716. The pressure head 716 moves downward to apply a set pressure to the punch. Module three 714 drives the electric screwdriver 713 to move downward. The output end of the electric screwdriver 713 drives the tightening sleeve 722 to rotate, applies a set torque to the nut on the stacking tooling, locks the tooling, and records data to form quality traceability data. After completion, the worker removes the product.

[0056] In the technical solution of a double-station punching sheet stacking device, a feeding unit 1 is provided to continuously feed the punching sheets, a stacking tool unit 2 is provided to place the stacking tool, a stacking unit 5 is provided to absorb the punching sheets from the feeding unit 1 and move them to the stacking tool unit 2 for stacking, a heating unit 6 is provided to heat and cure the stacked products, a pressing and twisting unit 7 is provided to apply set pressure and torque to the cured products, and lock the punching sheets; a double-station punching sheet stacking device in the technical solution realizes the automation of punching sheet stacking and ensures the consistency of product stacking. At the same time, double stacking stations are provided for stacking operations, which improves the work efficiency of stacking and can reduce staff and increase efficiency.

[0057] Specifically, to achieve continuous feeding of punching sheets, such as Figure 1 , Figure 2 , Figure 3As shown, the hollow rotating platform includes a second motor 109, the output end of the second motor 109 is connected to a turntable 110, and a plurality of core shafts 108 are arranged on the turntable 110. In this embodiment, four core shafts 108 are arranged.

[0058] The punching sheet is manually mounted on the punching sheet core shaft 108, and the motor 2 109 drives the turntable 110 to rotate, and the core shaft 108 corresponding to the feeding moves to the loading station, and the material taking part (vacuum suction nozzle 2 506, vacuum suction nozzle 1 311) takes the punching sheet from the core shaft 108 at the feeding position, and the core shaft 108 after feeding is manually replenished; in the feeding unit 1, four loading stations are designed with the function of automatic switching of feeding to realize continuous feeding of the punching sheets.

[0059] To ensure the stability of the position when punching and loading, Figure 1 , Figure 2 , Figure 3 As shown, the feeding unit 1 also includes a fixed rod upright plate 101 and a linear bearing 102. A lifting base plate 104 is provided at the lower end of the rod upright plate 101, and a motor 105 is provided on the lifting base plate 104. A guide column 103 passes through the linear bearing 102, and a lower lifting plate 106 is connected to the guide column 103. The output end of the motor 105 is engaged with the lower lifting plate 106 to drive the lower lifting plate 106 to move in the Z direction.

[0060] Specifically, the output end of the motor 105 is connected to a gear, and a longitudinally distributed rack is provided on the lower lifting plate 106. The gear is meshed with the rack. The forward or reverse rotation of the motor 105 drives the lower lifting plate 106 to move in the Z direction under the cooperation and limiting action of the linear bearing 102 and the guide column 103 through the meshing cooperation of the gear and the rack.

[0061] An upper lifting plate 107 cooperating with the lower lifting plate 106 is sleeved on the core shaft 108, that is, the upper lifting plate 107 is arranged at the position of the loading station. When the motor 105 drives the lower lifting plate 106 to move upward, the upper lifting plate 107 is pushed up synchronously, and the upper lifting plate 107 drives the punching sheet to move upward, so that the upper ends of the punching sheets at the loading station are at the same height position, ensuring that the positions of the punching sheets to be sucked are consistent and the stability of the feeding is ensured. When the motor 105 drives the lower lifting plate 106 to move downward, under the action of gravity, the upper lifting plate 107 moves downward to the initial position.

[0062] To ensure the stability of material collection, Figure 1 , Figure 2 , Figure 7 As shown, the output end of the four-axis manipulator 502 is connected to a nozzle base 503 , the nozzle base 503 is connected to a nozzle bottom plate 2 505 via an elastic member 2 504 , and a vacuum nozzle 2 506 is mounted on the nozzle bottom plate 2 505 .

[0063] An elastic member 504 is arranged between the output end of the four-axis manipulator 502 and the vacuum nozzle 506, so that when the vacuum nozzle 506 sucks the punching sheet, the rigid contact with the punching sheet is changed to flexible contact. The setting of flexible contact reduces the possibility of damage to the punching sheet and the vacuum nozzle 506, while ensuring stable contact between the vacuum nozzle 506 and the punching sheet, thereby ensuring stability in the material picking process.

[0064] The setting of the heating unit 6 heats and cures the stacked products. In order to improve the effect of heating and curing, Figure 1 , Figure 2 , Figure 8 As shown, the heating unit 6 includes a base 3 601 and a motor 4 603. The base 3 601 is provided with a guide column 2 602. The guide column 2 602 is provided with a high-frequency machine bottom plate 608 through a linear bearing 2 607. A high-frequency machine 606 is provided on the high-frequency machine bottom plate 608. The heating coil 605 is assembled at the output end of the high-frequency machine 606. The high-frequency machine 606 provides a high-frequency current for the heating coil 605.

[0065] The output end of motor four 603 is meshed with the high-frequency machine base plate 608, driving the high-frequency machine base plate 608 to move in the Z direction. Specifically, the output end of motor four 603 is connected to a gear, and a longitudinally distributed rack is provided on the high-frequency machine base plate 608. The gear and the rack are meshed. The forward or reverse rotation of motor four 603 drives the high-frequency machine base plate 608 to move in the Z direction through the meshing cooperation of the gear and the rack under the limiting action of the guide column two 602 and the linear bearing two 607. A sensor fixing two 604 is provided on the high-frequency machine base plate 608, and a sensor two is provided on the sensor fixing two 604. The setting of sensor two detects whether the punching sheet is in place.

[0066] The heating unit 6 in the present technical solution drives the heating coil 605 to move back and forth in the up and down directions through the forward or reverse rotation of the motor 4 603. After the stacked product moves to the heating position (below the heating coil 605), the heating coil 605 moves downward until the product is located inside the heating coil 605, and the product is heated for a specific time and at a specific temperature. The heating coil 605 is arranged to cover the outside of the product to improve the heating and curing effect, improve the heating uniformity of the heated product, and ensure product quality.

[0067] To achieve the setting requirement of the pressure head 716 moving in the Z direction, as Figure 1 , Figure 2 , Fig. 9As shown, the lower end of the pressing and screwing base plate 721 is connected to the press fixing plate 702 through the column three 703, and the press fixing plate 702 is equipped with a press 701. The press 701 can be set as a component that drives the stretching plate 704 to move linearly, such as a cylinder. The cylinder drives the stretching plate 704 to move in the up and down directions by controlling the overall length. The output end of the press 701 is connected to the stretching plate 704, and the stretching plate 704 is provided with a guide column three 706. The guide column three 706 penetrates the pressing and screwing base plate 721 and is connected to the pressure head base plate 708. The guide column three 706 and the pressing and screwing base plate 721 are matched by the linear bearing three 705, and the pressure head base plate 708 and the pressure head 716 are assembled by the pressure sensor 715; the pressure sensor 715 is set to detect the size of the pressure applied to the product to ensure that the applied pressure is at a normal value.

[0068] In this technical solution, the press 701 is in motion, driving the stretching plate 704 to move in the up and down directions. When the stretching plate 704 moves downward, the pressure head 716 is driven downward by the guide column three 706 and the pressure head bottom plate 708, applying pressure to the product in the pressurized position (below the pressure head 716) to fix the position of the punch. In order to improve the stability of the product during the pressing and twisting process, a pressure block 723 is provided on the pressing and twisting bottom plate 721, and the adapter bottom plate 2 719 is placed on the pressure block 723 to support the product during the pressing and twisting process.

[0069] like Figure 1 , Figure 2 , Figure 6 As shown, a double-station punching and stacking device also includes a positioning and photographing unit 4; the positioning and photographing unit 4 is set to identify the front and back sides of the punching sheet, identify whether the punching sheet has defects, and ensure the quality of the stacked product.

[0070] The positioning and photographing unit 4 includes an L-shaped vertical plate 403, on which a hollow rotating wheel 406 is rotatably arranged, on which a transparent bottom plate 407 is arranged, on which a punching sheet is placed, and on one side of the L-shaped vertical plate 403 a motor three 405 is arranged, and the output end of the motor three 405 is meshed with the hollow rotating wheel 406; specifically, the output end of the motor three 405 is provided with a gear, and the hollow rotating wheel 406 is provided with gear teeth, and the gears are meshed with the gear teeth, and the motor three 405 is powered on and started to realize the setting of driving the hollow rotating wheel 406 to rotate; the positioning and photographing unit 4 also includes a camera 402, which is assembled on a camera bottom plate 401, and the camera bottom plate 401 is connected to the L-shaped vertical plate 403 through a camera vertical plate 404.

[0071] After the material taking part (vacuum nozzle 1 311, vacuum nozzle 2 506) takes the punched sheet off from the feeding unit 1, it is placed on the transparent bottom plate 407, and the camera 402 takes a picture of the punched sheet for identification, including the angle, front and back sides of the punched sheet, etc.; in the process of identifying the punched sheet, the hollow rotating wheel 406 can be driven to rotate by the motor 3 405 to adjust the stacking angle of the punched sheet, and the punched sheet can be photographed at multiple angles at the same time to ensure the identification effect.

[0072] like Figure 1 , Figure 2 , Figure 5 As shown, a double-station punching sheet stacking device also includes a transfer unit 3; the transfer unit 3 is set up to replace the stacking unit 5, and the feeding unit 1 takes the material and places it at the position of the positioning and photographing unit 4. The transfer unit 3 takes the material from the feeding unit 1 and places it at the position of the positioning and photographing unit 4. The stacking unit 5 places the punching sheet at the position of the positioning and photographing unit 4 at the stacking tooling unit 2, so as to ensure the continuity of the stacking process.

[0073] The transfer unit 3 includes a module 2 305 arranged in the Y direction, and an upper and lower cylinders 307 are arranged at the output end of the module 2 305, and a nozzle bracket 308 is arranged at the output end of the upper and lower cylinders 307, and the nozzle bracket 308 is provided with a nozzle base plate 310 through an elastic member 309, and a vacuum nozzle 311 is mounted on the nozzle base plate 310; an elastic member 309 is arranged between the output end of the upper and lower cylinders 307 and the vacuum nozzle 311, so that when the vacuum nozzle 311 sucks the punching sheet, the rigid contact with the punching sheet is changed into a flexible contact, and the setting of the flexible contact reduces the possibility of damage to the punching sheet and the vacuum nozzle 311, and at the same time ensures the stable contact between the vacuum nozzle 311 and the punching sheet, thereby ensuring the stability of the material taking process.

[0074] The transfer unit 3 also includes a base 301, a column 302 is arranged on the base 301, a support 303 is arranged on the column 302, a module bottom plate 304 is arranged on the support 303, a module 2 305 is installed on the module bottom plate 304, a sensor fixing 1 306 is arranged on the module bottom plate 304, a sensor fixing 1 306 is arranged on the sensor fixing 1 306, and a sensor 1 is arranged on the sensor fixing 1 306. The setting of the sensor 1 detects whether the punching sheet is sucked successfully.

[0075] After the punch is in the loading station, module 2 305 drives vacuum nozzle 1 311 to move forward to the top of the punch, and the upper and lower cylinders 307 move downward to drive vacuum nozzle 1 311 to contact the punch and suck the punch. After the punch is sucked, the upper and lower cylinders 307 are reset, and module 2 305 moves backward to drive the punch to move to the top of the positioning and photographing unit 4. The upper and lower cylinders 307 move downward to drive the punch to be placed on the hollow rotating wheel 406, and the upper and lower cylinders 307 are reset to complete the process of picking up the punch from the feeding unit 1 to the positioning and photographing unit 4.

[0076] In order to expand the application range of this device, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Fig. 9 As shown, a tooling adapter plate 203 is detachably mounted on the adapter base plate 202, and the stacked tooling is arranged on the tooling adapter plate 203; the nozzle base plate 310 and the vacuum nozzle 311 are detachably connected; the output end of the four-axis manipulator 502 and the vacuum nozzle 2 506 are detachably connected; a tooling adapter plate 2 718 is detachably mounted on the adapter base plate 719, and the stacked tooling is arranged on the tooling adapter plate 718.

[0077] When punching sheets of different specifications need to be stacked, the tool adapter plate 203 and the tool adapter plate 718 suitable for the stacking tooling, and the vacuum suction nozzle 311 and the vacuum suction nozzle 506 suitable for the punching sheets can be replaced accordingly; the punching sheets of different specifications are mainly manifested in more than a dozen products with diameters ranging from Φ20mm-Φ100mm.

[0078] like Figure 1 , Figure 2 , Fig.10 As shown, a double-station punching sheet stacking device also includes a material receiving unit 8. The material receiving unit 8 is configured to collect the punching sheets when defects in the punching sheets are detected.

[0079] The material receiving unit 8 comprises a support plate 801 mounted on the second base 501, and a material receiving fixture 802 is arranged on the support plate 801. The material receiving fixture 802 mainly has a longitudinally arranged long axis.

[0080] When the positioning and photographing unit 4 detects that the punch has defects, including defects in the punch itself and the wrong position of the assembly surface of the punch, the vacuum suction nozzle 2 506 in the stacking unit 5 sucks the punch and moves it to the receiving unit 8 to sleeve the punch on the long axis.

[0081] The stacking process of the double-station punching stacking device includes the following steps:

[0082] 1. In the feeding unit 1, workers put the stack of punched sheets on the mandrel 108, and the four stations automatically switch to feed;
