Description

Technical Field

[0001] This application relates to the field of sheet metal feeding equipment, and more particularly to a sheet metal feeding device. Background Technology

[0002] A car hood lock is a mechanical device used to lock and unlock the engine hood. It is usually located at the front of the hood and is secured by a latch and a buckle structure. It is usually made of sheet metal.

[0003] In existing technologies, mounting plates are typically placed sequentially on a conveyor belt, and then robotic arms installed on both sides of the conveyor belt are used to grab and transfer the mounting plates. However, traditional conveyor belt conveying methods occupy a large area and require a large space to install the conveyor belt, which greatly occupies the factory's space and has its shortcomings. Utility Model Content

[0004] To address the issue of the large footprint of traditional conveyor belt conveying methods, this application provides a mounting plate loading device.

[0005] The mounting plate loading device provided in this application adopts the following technical solution:

[0006] A mounting plate loading device includes a loading platform and a feeding trolley. Several material trays are vertically stacked on the feeding trolley, each tray having several material slots for placing plates. A robotic arm for transferring plates is mounted on the loading platform. The loading platform also includes a transfer assembly, a lifting assembly, a clamping and fixing assembly, and a stacking assembly. The transfer assembly transfers the material trays from the feeding trolley to the loading platform. The lifting assembly lifts the transferred material trays to the robotic arm. The clamping and fixing assembly clamps and fixes the material trays. The stacking assembly stacks the material trays after the plates have been clamped.

[0007] By adopting the above technical solution, workers push the feeding cart with stacked trays to the side of the loading platform. Then, the transfer component transfers the stacked trays on the feeding cart to the bottom of the loading platform. Next, the lifting component lifts the stacked trays to a certain height. Then, the clamping and fixing component clamps and fixes the highest stacked tray. Subsequently, the mechanical handpiece transfers the boards in the trays one by one. Finally, the stacking component stacks the trays with transferred boards together, thus completing the board loading process. Through highly integrated design, the area occupied in the factory is reduced.

[0008] Optionally, the material transfer assembly includes two parallel conveyor frames disposed at the bottom of the loading platform. Both ends of the conveyor frames are rotatably equipped with synchronous pulleys. A synchronous belt is wound around the two synchronous pulleys on the same conveyor frame. A rotating component is disposed on the loading platform to drive the synchronous pulleys to rotate. Multiple support wheels are rotatably disposed on the feeding cart along the length of the conveyor frames. The material tray is stacked on the support wheels. The material tray on the feeding cart slides onto the synchronous belt through the support wheels.

[0009] By adopting the above technical solution, when the feeding car approaches the loading platform, the worker pushes the stacked material trays, and the material trays slide onto the synchronous belt through the support wheels. Then the rotating parts drive the synchronous wheels to rotate, and the synchronous wheels drive the synchronous belt to rotate. The synchronous belt drives one end of the stacked material trays to the other end of the conveyor frame.

[0010] Optionally, the rotating component includes a rotating motor mounted on the feeding platform. The rotating motor is electrically connected to the control system. A drive shaft is provided between the two synchronous pulleys at the same end of the two conveyor frames. A transmission belt is wound between the drive shaft and the output shaft of the rotating motor.

[0011] By adopting the above technical solution, the control system starts the rotating motor, and the output shaft of the rotating motor drives the drive shaft to rotate through the transmission belt. The rotating drive shaft drives the synchronous pulleys at both ends to rotate synchronously, thereby causing the synchronous belt to move the stacked material trays.

[0012] Optionally, the lifting assembly includes a lifting plate that is vertically slidably disposed on the loading platform. The lifting plate is located at one end of the conveyor frame opposite to the drive shaft and between the two conveyor frames. The loading platform is provided with a vertical plate and a vertical slide rail. The lifting plate is slidably disposed on the vertical slide rail. The vertical plate is provided with a lifting component that drives the lifting plate to slide vertically.

[0013] By adopting the above technical solution, when the stacked material trays move with the synchronous belt to the end of the conveyor frame facing away from the drive shaft, the stacked material trays are located above the lifting plate. The lifting component drives the lifting plate to rise, and the lifting plate lifts the stacked material trays to slide vertically upward, thereby facilitating the robot arm to clamp and transfer the materials.

[0014] Optionally, the lifting component includes a lifting screw rotatably mounted on the upright plate, a lifting plate threadedly connected to the lifting screw, a lifting motor electrically connected to the control system on the upright plate, and a lifting belt between the output shaft of the lifting motor and the lifting screw.

[0015] By adopting the above technical solution, the control system starts the lifting motor, and the output shaft of the lifting motor drives the lifting screw to rotate through the lifting belt. Under the restriction of the vertical slide rail, the rotating lifting screw causes the lifting plate to slide vertically.

[0016] Optionally, the clamping and fixing assembly includes a side plate disposed on the loading platform and located above the lifting plate. The side plate is located on opposite sides of the material tray. A side cylinder electrically connected to the control system is disposed on the side plate. An L-shaped tray plate is disposed on the piston rod of the side cylinder. A vertical cylinder is disposed on the loading platform and located above the lifting plate. The vertical cylinder is arranged at two opposite corners of the material tray. A diagonal cylinder is disposed on the piston rod of the vertical cylinder. A diagonal plate with an L-shaped cross-section is disposed on the piston rod of the diagonal cylinder. The diagonal plate is used to abut against the corner of the material tray. Both the vertical cylinder and the diagonal cylinder are electrically connected to the control system.

[0017] By adopting the above technical solution, after the lifting plate slides vertically a certain distance, the control system activates the side cylinder. The piston rod of the side cylinder extends and drives the pallet plate to move to the bottom of the highest stacked material tray. At this time, the control system reverses the output shaft of the lifting motor to lower the lifting plate a certain distance. Then, the control system activates the vertical cylinder and the diagonal cylinder. The vertical cylinder adjusts the height position of the diagonal cylinder through its piston rod. Then, the piston rod of the diagonal cylinder drives the diagonal plate to approach the corner of the material tray. Through the two diagonal cylinders and the side cylinder, the material tray on the pallet plate is clamped and positioned.

[0018] Optionally, the pallet assembly includes a pallet transfer plate slidably disposed on the loading platform, the pallet transfer plate being located between the lifting plate and the pallet plate, a horizontal slide rail being disposed on the loading platform along the sliding direction of the pallet transfer plate, the pallet transfer plate being slidably engaged with the horizontal slide rail, a rodless cylinder electrically connected to the control system being disposed on the loading platform, the pallet transfer plate being disposed on the slider of the rodless cylinder, and a pallet stacking component for stacking the material trays being disposed on the loading platform.

[0019] By adopting the above technical solution, after the material on the tray clamped and fixed by the diagonal cylinder is transferred, the control system starts the rodless cylinder. The slider of the rodless cylinder drives the transfer plate to move below the clamped and fixed tray. Then the control system controls the diagonal cylinder and the side cylinder to reset. At this time, the tray falls on the transfer plate. Then the control system controls the slider of the rodless cylinder to drive the transfer plate to reset. Finally, the stacking components will stack the trays placed on the transfer plate.

[0020] Optionally, the stacking component includes a mounting base plate disposed on the feeding platform and located on both sides of the sliding direction of the transfer plate. The mounting base plate is provided with a base plate cylinder, a primary stacking cylinder, and a secondary stacking cylinder. The base plate cylinder, the primary stacking cylinder, and the secondary stacking cylinder are all electrically connected to the control system. The extension direction of the piston rod of the base plate cylinder is perpendicular to the sliding direction of the transfer plate. The primary stacking cylinder is disposed on the piston rod of the base plate cylinder, and the secondary stacking cylinder is disposed on the piston rod of the primary stacking cylinder. The secondary stacking cylinder is vertically slidably arranged, and a bottom support plate is disposed on the piston rod of the secondary stacking cylinder. The bottom support plate is used to abut against the bottom of the material tray placed on the transfer plate.

[0021] By adopting the above technical solution, the control system activates the substrate cylinder, the primary stacking cylinder, and the secondary stacking cylinder. The piston rod of the primary stacking cylinder retracts, causing the secondary stacking cylinder to descend to a suitable position. Then, the piston rod of the secondary stacking cylinder extends, driving the material tray on the base plate to move to the top of the material tray placed on the transfer plate. Subsequently, the control system controls the piston rod of the substrate cylinder to retract, causing the material tray on the base plate to fall to the top of the material tray placed on the transfer plate. Then, the control system controls the primary and secondary stacking cylinders, causing the piston rod of the secondary stacking cylinder to drive the base plate to move to the bottom of the material tray placed on the transfer plate. Finally, the control system controls the piston rod of the substrate cylinder to extend, causing the base plate located on the piston rod of the secondary stacking cylinder to abut against the bottom of the material tray. Subsequently, the piston rod of the primary stacking cylinder extends, causing the base plate to drive the stacked material trays to rise.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Workers push the feeding cart with stacked trays to the loading platform. Then, the transfer component moves the stacked trays on the feeding cart to the bottom of the loading platform. The lifting component then lifts the stacked trays to a certain height. After that, the clamping and fixing component clamps and fixes the highest stacked tray. Then, the robotic arm transfers the boards in the trays one by one. Finally, the stacking component stacks the trays with transferred boards together, thus completing the board loading process. Through highly integrated design, the area occupied in the factory is reduced.

[0024] 2. After the lifting plate slides vertically a certain distance, the control system activates the side cylinder. The piston rod of the side cylinder extends and drives the pallet plate to the bottom of the highest stacked material tray. At this time, the control system reverses the output shaft of the lifting motor to lower the lifting plate a certain distance. Then, the control system activates the vertical cylinder and the diagonal cylinder. The vertical cylinder adjusts the height of the diagonal cylinder through its piston rod. Then, the piston rod of the diagonal cylinder drives the diagonal plate to approach the corner of the material tray. Through the two diagonal cylinders and the side cylinder, the material tray on the pallet plate is clamped and positioned.

[0025] 3. The control system activates the substrate cylinder, the primary stacking cylinder, and the secondary stacking cylinder. The piston rod of the primary stacking cylinder retracts, causing the secondary stacking cylinder to descend to a suitable position. Then, the piston rod of the secondary stacking cylinder extends, moving the material tray on the base plate to the top of the material tray placed on the transfer plate. Subsequently, the control system controls the piston rod of the substrate cylinder to retract, causing the material tray on the base plate to fall onto the top of the material tray placed on the transfer plate. Then, the control system controls the primary and secondary stacking cylinders, causing the piston rod of the secondary stacking cylinder to move the base plate to the bottom of the material tray placed on the transfer plate. Finally, the control system controls the piston rod of the substrate cylinder to extend, causing the base plate located on the piston rod of the secondary stacking cylinder to abut against the bottom of the material tray. Subsequently, the piston rod of the primary stacking cylinder extends, causing the base plate to lift the stacked material trays. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a mounting plate loading device.

[0033] Reference Figure 1 A mounting plate feeding device includes a feeding platform 1 and a feeding cart 2. Several material trays 3 are stacked vertically on the feeding cart 2. Several material trays 3 are provided on the material trays 3 for placing the plates 0. A robotic arm 5 for transferring the plates 0 is bolted to the top of the feeding platform 1.

[0034] Reference Figure 1 The loading platform 1 is equipped with a material transfer component 6, which is used to transfer the material tray 3 on the feeding car 2 to the loading platform 1.

[0035] Reference Figure 2 and Figure 3 The material transfer assembly 6 includes two parallel conveyor frames 61 bolted to the bottom of the feeding platform 1. Each end of the conveyor frame 61 is rotatably connected to a synchronous wheel 62. A synchronous belt 63 is wound around the two synchronous wheels 62 on the same conveyor frame 61. Multiple support wheels 65 are rotatably connected to the bottom of the feeding car 2 along the length of the conveyor frame 61. The material tray 3 is stacked on the support wheels 65.

[0036] Reference Figure 2 and Figure 3The loading platform 1 is equipped with a rotating component 64 that drives the synchronous wheel 62 to rotate. The rotating component 64 includes a rotating motor 641 bolted to the bottom of the loading platform 1. The rotating motor 641 is electrically connected to the control system. A drive shaft 642 is provided between the two synchronous wheels 62 at the same end of the two conveyor frames 61. Pulleys 10 are provided on both the drive shaft 642 and the output shaft of the rotating motor 641. A transmission belt 643 is wound between the pulleys 10 on the drive shaft 642 and the pulleys 10 on the output shaft of the rotating motor 641. The material tray 3 on the feeding car 2 slides onto the synchronous belt 63 through the support wheel 65.

[0037] The worker pushes the feeding cart 2, which has the stacked material trays 3, to the side of the loading platform 1, and then pushes the stacked material trays 3. The material trays 3 slide onto the synchronous belt 63 via the support wheels 65. After that, the control system starts the rotating motor 641. The output shaft of the rotating motor 641 drives the drive shaft 642 to rotate via the transmission belt 643. The rotating drive shaft 642 drives the synchronous wheels 62 at both ends to rotate synchronously. The synchronous wheels 62 drive the synchronous belt 63 to rotate, and the synchronous belt 63 drives the stacked material trays 3 to move.

[0038] Reference Figure 2 The loading platform 1 is equipped with a lifting component 7, which is used to lift the material tray 3 transferred to the loading platform 1 to the robot arm 5.

[0039] Reference Figure 2 and Figure 3 The lifting assembly 7 includes a lifting plate 71 that is vertically slidably arranged on the loading platform 1. The lifting plate 71 is located at one end of the conveyor frame 61 facing away from the drive shaft 642. The lifting plate 71 is located between two conveyor frames 61. A vertical plate 72 is bolted to the loading platform 1. A vertical slide rail 73 is bolted to the vertical plate 72. The lifting plate 71 is slidably arranged on the vertical slide rail 73. A lifting component 74 that drives the lifting plate 71 to slide vertically is arranged on the vertical plate 72.

[0040] Reference Figure 2 and Figure 3 The lifting component 74 includes a lifting screw 741 rotatably connected to the vertical plate 72, a lifting plate 71 threadedly connected to the lifting screw 741, a lifting motor 742 electrically connected to the control system and bolted to the vertical plate 72, and lifting pulleys 11 arranged on the output shaft of the lifting motor 742 and the end of the lifting screw 741, and a lifting belt 743 is wound together between the lifting pulleys 11 on the output shaft of the lifting motor 742 and the lifting pulleys 11 on the lifting screw 741.

[0041] The stacked material trays 3 move along the synchronous belt 63 to one end of the conveyor frame 61 facing away from the drive shaft 642. At this time, the stacked material trays 3 are located above the lifting plate 71. Then, the control system starts the lifting motor 742. The output shaft of the lifting motor 742 drives the lifting screw 741 to rotate through the lifting belt 743 and the lifting pulley 11. Under the restriction of the vertical slide rail 73, the rotating lifting screw 741 causes the lifting plate 71 to slide vertically upward. The lifting plate 71 drives the stacked material trays 3 to move vertically upward a certain distance.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The feeding platform 1 is provided with a clamping and fixing component 8, which is used to clamp and fix the material tray 3. The clamping and fixing component 8 includes a side plate 81 that is bolted to the feeding platform 1 and located above the lifting plate 71. The side plate 81 is located on opposite sides of the material tray 3.

[0043] Reference Figure 3 A side cylinder 82, which is electrically connected to the control system, is bolted to the side plate 81. A tray plate 83 with an L-shaped cross-section is bolted to the piston rod of the side cylinder 82. A vertical cylinder 84 is bolted to the loading platform 1 and above the lifting plate 71.

[0044] Reference Figure 3 Vertical cylinder 84 is arranged at two opposite corners of the material tray 3. Diagonal cylinder 85 is bolted to the piston rod of vertical cylinder 84. Diagonal plate 86 with an L-shaped cross section is bolted to the piston rod of diagonal cylinder 85. Diagonal plate 86 is used to abut against the corner of material tray 3. Both vertical cylinder 84 and diagonal cylinder 85 are electrically connected to the control system.

[0045] The control system activates the side cylinder 82, and the piston rod of the side cylinder 82 extends. The piston rod of the side cylinder 82 drives the pallet plate 83 to move to the bottom of the highest stacked material tray 3. Then, the control system activates the vertical cylinder 84 and the diagonal cylinder 85. The vertical cylinder 84 adjusts the height position of the diagonal cylinder 85 through its piston rod. At the same time, the piston rod of the diagonal cylinder 85 drives the diagonal plate 86 to move closer to the corner of the material tray 3. Through the two diagonal cylinders 85 and the side cylinder 82, the material tray 3 on the pallet plate 83 is clamped and fixed.

[0046] Reference Figure 3 and Figure 4 The loading platform 1 is equipped with a stacking tray assembly 9, which is used to stack the material trays 3 after the plates 0 have been clamped. The stacking tray assembly 9 includes a transfer plate 91 that is horizontally slidably arranged on the loading platform 1. The transfer plate 91 is located between the lifting plate 71 and the pallet plate 83.

[0047] Reference Figure 3 and Figure 4 A horizontal slide rail 92 is bolted to the loading platform 1 along the sliding direction of the transfer plate 91. The transfer plate 91 and the horizontal slide rail 92 are slidably engaged. A rodless cylinder 93 electrically connected to the control system is bolted to the loading platform 1. The transfer plate 91 is bolted to the slider of the rodless cylinder 93. A stacking piece 94 for stacking the material tray 3 is arranged on the loading platform 1.

[0048] Reference Figure 3 and Figure 4 The stacking component 94 includes a mounting base plate 941 bolted to the loading platform 1 and located on both sides of the sliding direction of the transfer plate 91. A base plate cylinder 942, a primary stacking cylinder 943 and a secondary stacking cylinder 944 are arranged on the mounting base plate 941. The base plate cylinder 942, the primary stacking cylinder 943 and the secondary stacking cylinder 944 are all electrically connected to the control system. The extension direction of the piston rod of the base plate cylinder 942 is perpendicular to the sliding direction of the transfer plate 91.

[0049] Reference Figure 3 and Figure 4 The first-stage stacking cylinder 943 is bolted to the piston rod of the base plate cylinder 942, and the second-stage stacking cylinder 944 is bolted to the piston rod of the first-stage stacking cylinder 943. The second-stage stacking cylinder 944 is arranged vertically and slides. A bottom plate 945 is bolted to the piston rod of the second-stage stacking cylinder 944. The bottom plate 945 is used to abut against the bottom of the material tray 3 placed on the transfer plate 91.

[0050] After the plate 0 on the material tray 3, which is clamped and fixed by the diagonal cylinder 85, is transferred, the control system controls the output shaft of the lifting motor 742 to rotate in the opposite direction, causing the lifting plate 71 to descend a certain distance. At this time, the clamped and fixed material tray 3 is separated from the material tray 3 below it by a certain distance. Then, the control system starts the rodless cylinder 93.

[0051] The slider of the rodless cylinder 93 drives the transfer plate 91 to move to the bottom of the clamped and fixed material tray 3. Then, the control system controls the diagonal cylinder 85 and the side cylinder 82 to reset. At this time, the material tray 3 falls on the transfer plate 91. Finally, the control system controls the slider of the rodless cylinder 93 to drive the transfer plate 91 to reset.

[0052] At the same time, the control system controls the output shaft of the lifting motor 742 to rotate in the forward direction again, so that the lifting plate 71 rises a certain distance again. Then the control system starts the diagonal cylinder 85 and the side cylinder 82 again, so that the material tray 3 located at the top of the lifting plate 71 is clamped and fixed again.

[0053] The control system activates the base plate cylinder 942, the first-stage stacking cylinder 943, and the second-stage stacking cylinder 944. The piston rod of the first-stage stacking cylinder 943 retracts, causing the second-stage stacking cylinder 944 to descend to the appropriate position. Then, the piston rod of the second-stage stacking cylinder 944 extends, and the material tray 3 located on the base plate 945 moves to the top of the material tray 3 placed on the transfer plate 91.

[0054] Subsequently, the control system controls the piston rod of the base plate cylinder 942 to retract, and the material tray 3 on the bottom plate 945 will fall on top of the material tray 3 placed on the transfer plate 91. Then, the control system controls the first-stage stacking cylinder 943 and the second-stage stacking cylinder 944, so that the piston rod of the second-stage stacking cylinder 944 drives the bottom plate 945 to move to the bottom of the material tray 3 placed on the transfer plate 91.

[0055] Finally, the piston rod of the control board cylinder 942 extends, causing the bottom plate 945 located on the piston rod of the secondary stacking cylinder 944 to abut against the bottom of the material tray 3. Subsequently, the piston rod of the primary stacking cylinder 943 extends, causing the bottom plate 945 to drive the stacked material tray 3 to rise, thereby completing the stacking process of the material tray 3.

[0056] The implementation principle of the mounting plate feeding device in this application embodiment is as follows: The worker pushes the feeding cart 2 with the stacked material trays 3 to the side of the feeding platform 1, and then pushes the stacked material trays 3. The material trays 3 slide onto the synchronous belt 63 through the support wheels 65. Then, the control system starts the rotating motor 641. The output shaft of the rotating motor 641 drives the drive shaft 642 to rotate through the transmission belt 643. The rotating drive shaft 642 drives the synchronous wheels 62 at both ends to rotate synchronously. The synchronous wheels 62 drive the synchronous belt 63 to rotate. The synchronous belt 63 drives the stacked material trays 3 to move.

[0057] The stacked material trays 3 move along the synchronous belt 63 to one end of the conveyor frame 61 facing away from the drive shaft 642. At this time, the stacked material trays 3 are located above the lifting plate 71. Then, the control system starts the lifting motor 742. The output shaft of the lifting motor 742 drives the lifting screw 741 to rotate through the lifting belt 743 and the lifting pulley 11. Under the restriction of the vertical slide rail 73, the rotating lifting screw 741 causes the lifting plate 71 to slide vertically upward. The lifting plate 71 drives the stacked material trays 3 to move vertically upward a certain distance.

[0058] The control system activates the side cylinder 82, and the piston rod of the side cylinder 82 extends. The piston rod of the side cylinder 82 drives the pallet plate 83 to move to the bottom of the highest stacked material tray 3. Then, the control system activates the vertical cylinder 84 and the diagonal cylinder 85. The vertical cylinder 84 adjusts the height position of the diagonal cylinder 85 through its piston rod. At the same time, the piston rod of the diagonal cylinder 85 drives the diagonal plate 86 to move closer to the corner of the material tray 3. Through the two diagonal cylinders 85 and the side cylinder 82, the material tray 3 on the pallet plate 83 is clamped and fixed.

[0059] After the plate 0 on the material tray 3, which is clamped and fixed by the diagonal cylinder 85, is transferred, the control system controls the output shaft of the lifting motor 742 to rotate in the opposite direction, causing the lifting plate 71 to descend a certain distance. At this time, the clamped and fixed material tray 3 is separated from the material tray 3 below it by a certain distance. Then, the control system starts the rodless cylinder 93.

[0060] The slider of the rodless cylinder 93 drives the transfer plate 91 to move to the bottom of the clamped and fixed material tray 3. Then, the control system controls the diagonal cylinder 85 and the side cylinder 82 to reset. At this time, the material tray 3 falls on the transfer plate 91. Finally, the control system controls the slider of the rodless cylinder 93 to drive the transfer plate 91 to reset.

[0061] At the same time, the control system controls the output shaft of the lifting motor 742 to rotate in the forward direction again, so that the lifting plate 71 rises a certain distance again. Then the control system starts the diagonal cylinder 85 and the side cylinder 82 again, so that the material tray 3 located at the top of the lifting plate 71 is clamped and fixed again.

[0062] The control system activates the base plate cylinder 942, the first-stage stacking cylinder 943, and the second-stage stacking cylinder 944. The piston rod of the first-stage stacking cylinder 943 retracts, causing the second-stage stacking cylinder 944 to descend to the appropriate position. Then, the piston rod of the second-stage stacking cylinder 944 extends, and the material tray 3 located on the base plate 945 moves to the top of the material tray 3 placed on the transfer plate 91.

[0063] Subsequently, the control system controls the piston rod of the base plate cylinder 942 to retract, and the material tray 3 on the bottom plate 945 will fall on top of the material tray 3 placed on the transfer plate 91. Then, the control system controls the first-stage stacking cylinder 943 and the second-stage stacking cylinder 944, so that the piston rod of the second-stage stacking cylinder 944 drives the bottom plate 945 to move to the bottom of the material tray 3 placed on the transfer plate 91.

[0064] Finally, the piston rod of the control board cylinder 942 extends, causing the bottom plate 945 located on the piston rod of the secondary stacking cylinder 944 to abut against the bottom of the material tray 3. Subsequently, the piston rod of the primary stacking cylinder 943 extends, causing the bottom plate 945 to drive the stacked material tray 3 to rise, thereby completing the stacking process of the material tray 3.

[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.
