A feeding rod 308 for feeding the pusher plate is set on the top surface of the turntable 306. A hopper lifting block 307 is sleeved on the feeding rod 308. The second servo motor 301 drives its first synchronous wheel to rotate, which in turn drives the first synchronous wheel 304 on the pusher plate divider 302 to rotate. The rotation of the first synchronous wheel 304 provides power to the pusher plate divider 302, thereby driving the gear set inside the pusher plate divider 302 to rotate, which in turn drives the turntable 306 to rotate. The turntable 306 drives the feeding rod 308 and the pusher plate on it to move to the position of the pusher plate lifting mechanism.

[0098] like Figure 3 As shown, in some embodiments, the pusher supply unit 30 further includes a pusher lifting mechanism, which includes: a third servo motor 309, which is fixedly mounted on the second support plate 311 and located below the second support plate 311; a drive shaft 319 is connected to the output end of the third servo motor 309; a second synchronous pulley 310 is keyed to the drive shaft 319; a lifting bracket 313 is disposed on the top surface of the second support plate 311; a linear guide shaft 314 is vertically disposed on the lifting bracket 313; a lifting plate 316 can form a linkage structure with the hopper lifting block 307 and is slidably disposed on the linear guide shaft 314 through a linear bearing; a third synchronous pulley 318 is rotatably disposed on the lifting bracket 313 through a rotating shaft; a first synchronous belt 312 drives the second synchronous pulley 310 and the third synchronous pulley 318; and a belt clamping block 315 is fixedly disposed on the first synchronous belt 312 and fixedly connected to the lifting plate 316. The third servo motor 309 drives the first synchronous belt 312 and the second synchronous pulley 310. The movement of the first synchronous belt 312 drives the indicator plate 316. The linear bearing moves up and down on the linear guide shaft 314. The lifting plate 316, carrying the hopper lifting block 307, moves the push plate to the gripping position of the push plate gripping mechanism 40.

[0099] like Figure 3As shown, in some embodiments, the push-plate gripping mechanism 40 includes: a second bracket, the second bracket including a second support column 401 and a cylinder fixing plate 405, the second support column 401 is mounted on the second support plate 311, the cylinder fixing plate 405 is mounted on the top of the second support column 401, the cylinder fixing plate 405 is mounted on the second rodless cylinder 406 and a cylinder protective cover 407 for protecting the second rodless cylinder 406, the movable block of the second rodless cylinder 406 is mounted on the second lifting cylinder 404, the piston top of the second lifting cylinder 404 is mounted on the three-jaw cylinder 403, the claws of the three-jaw cylinder 403 are mounted on the push-plate gripper 402, the second lifting cylinder 404 descends, moves the three-jaw cylinder 403 to the gripping position, after the push-plate is in place, the three-jaw cylinder 403 starts and clamps through the push-plate gripper 402, then the second lifting cylinder 404 rises, and the second rodless cylinder 406 moves the three-jaw cylinder 403 to the first turntable unit.

[0100] The small push-tray feeding is achieved through the action of the push-tray supply unit 30 and the push-tray gripping mechanism 40. The push-tray supply unit 30 provides more storage space for the small push-tray feeding, reduces the number of feeding times, and provides a fixed gripping position for the push-tray gripping mechanism 40.

[0101] Both the pusher plate supply unit 30 and the pusher plate gripping mechanism 40 use a robotic arm cylinder structure to replace employees in installing the pusher plate, thus achieving the same effect of freeing up manpower, allowing personnel to do other work and improving their work efficiency.

[0102] like Figure 4 and Figure 5 As shown, in some embodiments, the first turntable unit includes: a riveting turntable 504, which is mounted on the rotating shaft of the divider 501.

A push plate positioning seat assembly is mounted on the top surface of each fixed seat 505. The push plate positioning seat assembly includes a base 507 disposed on the fixed seat 505. A movable sleeve 509 is fixedly provided on the top surface of the base 507. The movable sleeve 509 has an internally hollow movable shaft 510. The movable shaft 510 has a positioning sleeve 511 inside. A guide rod 506 and a return spring 508 are provided between the movable shaft 510 and the base 507. The push plate assembly 150 is inserted into the positioning sleeve 511.

[0103] like Figure 4 As shown, in some embodiments, the first drive unit includes: a divider 501, which is mounted on the top surface of the second support plate 311, and a motor mounting plate 502 is mounted on the side of the divider 501. A fourth servo motor 503 that provides power to the divider 501 is mounted on the motor mounting plate 502.

[0104] The first rotating mechanism 50 is driven by a motor to automatically move the push disc positioning seat assembly to the position directly below the first riveting unit 60 for riveting. This step does not require manual intervention and is entirely dependent on the program set by the equipment. Therefore, this process avoids the possibility of safety accidents caused by personnel and also avoids quality defects caused by the substandard skills of employees, as the riveting positioning work is controlled by the equipment.

[0105] The first rotating disc unit 50 also forms a cycle through rotation for the riveting action. The above cycle involves structures forming a first driving unit, which divides one process into three steps through the rotating disc and the grabbing mechanism to reduce the operation time of a single process.

[0106] As shown in Figure 4 In an embodiment, the two riveting units include a first riveting unit and a second riveting unit that are substantially identical in structure. The first riveting unit 60 includes a riveting machine 601, a riveting head 602, and a riveting base 603. The riveting head 602 is installed on the riveting machine 601, and the riveting base 603 is located directly below the riveting head 602. When the push disc positioning seat assembly on the first rotating disc unit rotates to the riveting base 603, the riveting machine 601 descends, and the riveting head 602 rotates to rivet the push disc assembly 150.

[0107] As shown in Figure 6 In some embodiments, the turnover grabbing mechanism 80 includes a third support frame, which includes a third support column 801 and a first direction shaft mounting plate 804. The third support column 801 is installed on the top surface of the second support plate 311, and the first direction shaft mounting plate 804 is installed on the top end of the third support column 801.

Since the second finger air cylinder 808 clamps the push disc assembly 150 from the push disc positioning seat assembly, when the second finger air cylinder 808 is clamped, the second direction shaft servo cylinder 803 is activated to rise to a safe position, the rotary air cylinder 802 is activated to turn 180°, and at the same time, the first direction shaft servo cylinder 805 is activated to move the push disc assembly 150 from the first rotating disc unit side to the second rotating disc unit side. After the first direction shaft servo cylinder 805 is in place, the second direction shaft servo cylinder 803 is activated to lower the push disc assembly 150 into the push disc positioning seat assembly of the second rotating disc unit.

[0108] The turnover grabbing mechanism 80 can move and place the push disc assembly 150 by the action of the mechanical arm and the cylinder Figure 4 The push disc positioning seat assembly of the first disc rotating mechanism is transferred and placed in the second rotating disc unit Figure 7 The second rotating disc unit has the advantages of continuous flow production, reduced handling times and steps of placing, which is a step of transferring and placing in the original process. The push disc riveting and the middle shell 140 riveting are performed by two devices, and the work of transferring and placing is required in between. If the push disc assembly 150 is manually taken and installed by the staff without the module, the production efficiency will be affected, the labor cost will be increased, and there will be safety hazards in the automatic device.

[0109] The turnover grabbing mechanism 80 combines the functions of taking, placing, moving and turning by a simple combination of a cylinder and an electric cylinder, and the turning reduces the process steps during the movement, so that the device structure is simpler and the cost is reduced.
