Description

Technical Field

[0001] This utility model applies to the field of automated production line equipment technology and provides a material unloading and storage line for home appliance door panels. Background Technology

[0002] In the home appliance manufacturing process, for optimal assembly efficiency, a finished product is usually broken down into multiple semi-finished products. Each semi-finished product is produced on an independent production line and then transferred to the final assembly line via containers such as trolleys for assembly. The semi-finished appliance door panel 500 mentioned in the following description of this utility model is a washing machine door panel component. This plate-shaped assembly is generally transferred manually from the production line to a semi-finished product storage trolley for stacking and storage. However, in actual operation, the semi-finished appliance door panel 500 is relatively heavy, and relying solely on manual operation is very laborious and inefficient. At the same time, the semi-finished product storage trolley also needs to be transferred and transported manually by pushing and pulling, resulting in low automation. Manual operation can also easily damage the appearance of the semi-finished appliance door panel 500. Utility Model Content

[0003] Therefore, this utility model provides a material unloading and storage line for home appliance door panels. A trolley hooking mechanism is set at intervals on the trolley transport chain. The trolley hooking mechanism hooks the semi-finished product storage trolleys through the trolley one-way hook. Then, the trolley transport chain drives multiple semi-finished product storage trolleys to be transported automatically. The trolley blocking mechanism fixes the semi-finished product storage trolleys to be placed in the designated position. Finally, the workpiece transfer device transfers the semi-finished home appliance door panels from the workpiece conveyor line to the semi-finished product storage trolleys. The whole process is automated and more efficient.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a household appliance door panel unloading and storage line, comprising:

[0005] A workpiece conveyor line, used for transporting semi-finished appliance door panels;

[0006] A trolley conveyor line includes several semi-finished product storage trolleys arranged sequentially above the trolley conveyor line along the transport direction. The trolley conveyor line includes a trolley transport chain, and several trolley hooking mechanisms are spaced apart along the transport direction on the trolley transport chain. Each trolley hooking mechanism includes a hooking base, and at least one trolley one-way hook is rotatably mounted on the hooking base. A hook body reset elastic element is also provided between the trolley one-way hook and the hooking base. The hooking base is also provided with a hook body limiting block. After the trolley one-way hook rotates a certain angle along the side opposite to the transport direction of the trolley conveyor line, it will abut against the hook body limiting block to prevent it from continuing to rotate. The semi-finished product storage trolley includes a trolley frame, and a trolley hooking rod adapted to the trolley one-way hook is provided at the lower part of the trolley frame.

[0007] The workpiece transfer device includes a multi-axis manipulator, the actuating end of which is connected to a door panel gripping mechanism, which is equipped with several door panel suction cups.

[0008] Furthermore, a trolley blocking mechanism is provided on the side of the trolley transport chain, the trolley blocking mechanism including a telescopic blocking shaft facing the trolley transport chain and a blocking shaft driving device capable of driving the telescopic blocking shaft to extend and retract.

[0009] Furthermore, the lower end of the trolley frame is provided with several trolley displacement wheels, and trolley guide plates are respectively provided on both sides of the trolley transport chain. The several trolley displacement wheels of the semi-finished product storage trolley are all located between the trolley transport chain and the trolley guide plates.

[0010] Furthermore, the trolley blocking mechanism also includes a trolley positioning guide block disposed on the side facing the trolley transport chain. The trolley positioning guide block includes a trolley guiding slope, and the trolley centering slope is inclined to the side facing the trolley transport chain.

[0011] Furthermore, trolley centering guide wheels are installed on the lower parts of both sides of the trolley frame at the height of the trolley positioning guide blocks.

[0012] Furthermore, the trolley hook rod is provided with at least one hook body guide groove, and the hook body guide groove is adapted to the trolley one-way hook of the trolley hooking mechanism.

[0013] Furthermore, it also includes a defective product transport line, wherein the trolley frame is equipped with several door panel placement tracks.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In the solution of this utility model, the trolley one-way hook, which can be elastically reset, abuts against the rear side of the trolley hook connecting rod. At the same time, the elastic reset structure of the trolley one-way hook can remind the operator whether the semi-finished product storage trolley is in place. Driven by the trolley transport chain, the semi-finished product storage trolley automatically moves forward for transportation. At the end of the trolley transport chain, the trolley one-way hook follows the trolley transport chain and automatically moves down from the upper end of the trolley transport chain to the lower end of the trolley transport chain, thereby disengaging from the semi-finished product storage trolley. The semi-finished product storage trolley then stays at the end of the trolley transport chain and waits for the next semi-finished product storage trolley to push it forward. This process is repeated, and multiple semi-finished product storage trolleys can be arranged in a neat order, waiting for subsequent retrieval.

[0016] 2. The semi-finished product storage trolley is blocked at the product loading position by the telescopic blocking shaft of the trolley blocking mechanism. At the same time, the trolley positioning guide block and the trolley centering guide wheel are used to make the semi-finished product storage trolley automatically center and enter the most accurate loading position.

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] Example, see attached document Figure 1 Appendix Figure 2 The present invention provides a material unloading and storage line for home appliance door panels, including a workpiece conveyor line 100, a trolley conveyor line 200, a defective product transport line 600, and a workpiece transfer device 300. The workpiece conveyor line 100 is used to transport semi-finished home appliance door panels 500. Several semi-finished product storage trolleys 400 are arranged sequentially above the trolley conveyor line 200 along the transport direction. The semi-finished home appliance door panels 500 on the workpiece conveyor line 100 have been sorted into good and defective products in sequence. The workpiece transfer device 300 can transfer the good products to the semi-finished product storage trolleys 400 on the workpiece conveyor line 100 and transfer the defective products to the defective product transport line 600.

[0035] Specifically, refer to the appendix Figure 5 The content of the trolley conveyor line 200 includes a trolley transport chain 210, which is a circular circulating chain. Several trolley hooking mechanisms 220 are spaced apart along the transport direction on the trolley transport chain 210. The trolley hooking mechanisms 220 move in a circular cycle under the drive of the trolley transport chain 210. (See attached diagram.) Figure 7 The content of the trolley hooking mechanism 220 includes a hooking base 221, on which at least one trolley one-way hook 222 is rotatably mounted. A hook body reset elastic element 223 is also provided between the trolley one-way hook 222 and the hooking base 221. The hooking base 221 is also provided with a hook body limiting block 224. After the trolley one-way hook 222 rotates a certain angle along the side opposite to the transport direction of the trolley conveyor line 200, it will abut against the hook body limiting block 224, thus preventing it from continuing to rotate. In this structure, the trolley one-way hook 222 can rotate forward under the action of external force and return to its initial position after the external force is removed. At the same time, when the trolley one-way hook 222 rotates backward under the action of external force, its rotation stroke is limited by the hook body limiting block 224. (See attached diagram) Figure 6The semi-finished product storage trolley 400 includes a trolley frame 410, within which are several door panel placement rails 450 for storing semi-finished appliance door panels 500. The lower end of the trolley frame 410 is equipped with several trolley displacement wheels 440, and the lower part of the trolley frame 410 is equipped with a trolley hook connecting rod 420 adapted to the trolley one-way hook 222. The trolley one-way hook 222 can hook onto the trolley hook connecting rod. The rear end of 420 is driven forward by the trolley transport chain 210. Simultaneously, the trolley hook rod 420 is equipped with at least one hook guide groove 430. The hook guide groove 430 is matched one-to-one with the trolley one-way hook 222 of the trolley hooking mechanism 220. When the trolley one-way hook 222 hooks the trolley hook rod 420, it precisely engages within the hook guide groove 430. The positional relationship between the trolley hooking mechanism 220 and the trolley hook rod 420 at this time is shown in the attached figure. Figure 3 As shown, this structure can further improve the stability of the connection between the two.

[0036] Meanwhile, in order to secure the semi-finished product storage trolley 400 to the designated loading position, a trolley blocking mechanism 230 is provided on the side of the trolley transport chain 210, as shown in the attached document. Figure 4 Appendix Figure 8 The content includes a trolley blocking mechanism 230, comprising a telescopic blocking shaft 231 facing the trolley transport chain 210 and a blocking shaft drive device 232 capable of driving the telescopic blocking shaft 231 to extend and retract. The trolley blocking mechanism 230 also includes a trolley positioning guide block 233 facing one side of the trolley transport chain 210. The trolley positioning guide block 233 includes a trolley guide ramp, which is inclined towards the trolley transport chain 210. Simultaneously, trolley guide plates 240 are respectively provided on both sides of the trolley transport chain 210. (The last sentence appears to be incomplete and possibly refers to a semi-finished product.) Several trolley displacement wheels 440 of the storage trolley 400 are set between the trolley transport chain 210 and the trolley guide plate 240. Correspondingly, trolley centering guide wheels are set at the lower part of both sides of the trolley frame 410 at the height of the trolley positioning guide block 233. When the semi-finished product storage trolley 400 reaches the position close to the trolley blocking mechanism 230, the trolley frame 410 can achieve centering correction under the action of the trolley centering guide wheel and the trolley positioning guide block 233, so as to ensure the accurate position of the semi-finished product storage trolley 400.

[0037] See attached document Figure 9The workpiece transfer device 300 includes a multi-axis robot 310, which is existing technology. The actuating end of the multi-axis robot 310 is connected to a door panel gripping mechanism 320. The door panel gripping mechanism 320 is equipped with several door panel suction cups 330. The door panel suction cups 330 can be used to adsorb the semi-finished appliance door panel 500 to be transferred on the workpiece conveyor line 100. The multi-axis robot 310 can be used to straighten the semi-finished appliance door panel 500 to a specified angle and place it in the semi-finished product storage trolley 400 or the defective product transport line 600 at the specified loading position.

[0038] The operating principle of this embodiment is as follows:

[0039] During production line operation, the empty semi-finished product storage trolley 400 is first manually moved to the beginning of the trolley transport chain and pushed forward along the transport chain. During this pushing process, the trolley hook rod 420 gradually approaches from behind one of the trolley hooking mechanisms 220 until its front end abuts against the trolley one-way hook 222 of the hooking mechanism 220. Then, the semi-finished product storage trolley 400 continues to be pushed forward manually. During this process, the trolley hook rod 420 presses forward against the trolley one-way hook 222, causing the trolley one-way hook 222 to rotate forward until the trolley hook rod 420 completely passes through the trolley one-way hook 222. At this point, the trolley one-way hook 222... 2. Under the action of the hook body reset elastic element 223, it will return to its initial state. At the same time, when the trolley one-way hook 222 elastically returns, it will make a metallic clanging sound, which can also help the operator judge whether it is installed in place. When the trolley transport chain 210 drives the trolley hooking mechanism 220 to move forward, the front end of the trolley one-way hook 222 will abut against the rear end of the trolley hooking rod 420. After that, the forward-moving trolley one-way hook 222 will drive the entire semi-finished product storage trolley 400 to move forward. During the process of the trolley one-way hook 222 driving the semi-finished product storage trolley 400 forward, due to the existence of the hook body limit block 224, the trolley one-way hook 222 will move forward under the action of the reaction force of the trolley hooking rod 420. After rotating a certain angle, it will abut against the hook body limiting block 224, thus preventing it from continuing to rotate. This ensures that the unidirectional hook 222 of the trolley will not disengage from the trolley hook connecting rod 420 during transportation. When the semi-finished product storage trolley 400 moves behind the trolley blocking mechanism 230, the telescopic blocking shaft 231 of the trolley blocking mechanism 230 pops out and jams the semi-finished product storage trolley 400. At the same time, the trolley positioning guide blocks 233 of the two trolley blocking mechanisms 230 center and correct the position of the semi-finished product storage trolley 400, so that it is in the most accurate loading position. At this time, the trolley transport chain 210 stops running, and the workpiece transfer device 300 begins to transfer the qualified appliance door panel semi-finished products 500 on the workpiece conveyor line 100 to the semi-finished product storage trolley 400 in sequence. The door panel is placed on track 450. After the semi-finished product storage trolley 400 is fully loaded, the telescopic blocking shaft 231 retracts, and the trolley transport chain 210 continues to run, moving the fully loaded semi-finished product storage trolley 400 towards the end of the trolley transport chain 210. When the fully loaded semi-finished product storage trolley 400 reaches the end of the trolley transport chain 210, the circulating chain structure of the trolley transport chain 210 will drive the trolley hooking mechanism 220 downwards away from the trolley hooking rod 420. At this time, the semi-finished product storage trolley 400 disengages from the trolley one-way hook 222 and remains at the end of the trolley transport chain 210. The trolley hooking mechanism 220 will then return to the beginning of the trolley transport chain 210 under the cyclical operation of the trolley transport chain 210 for the next transportation process.The semi-finished product storage trolley 400 that remains stationary will be pushed forward from the trolley transport chain 210 by the next semi-finished product storage trolley 400. To ensure the subsequent semi-finished product storage trolleys 400 are arranged neatly, the trolley guide plates 240 can be extended forward. This way, the semi-finished product storage trolleys 400 leaving the trolley transport chain 210 will be arranged sequentially along the direction of the two extending trolley guide plates 240, facilitating retrieval by the next process.
