The upper cover is in the material area, and the operator uses a special grabbing device to grab the upper cover to the preparation station. After the upper cover is placed at the preparation station, the glue edge of the upper cover is cleaned with a cleaning agent. The cleaned upper cover is transported to the gluing station through the conveyor line. When it arrives at the gluing station, the gluing positioning mechanism will position the upper cover. After positioning, the industrial robot is equipped with a glue gun to apply a high-rigidity sealant on the edge of the upper cover. After gluing, the conveyor line will transport the upper cover to the removal station.

[0003] The existing cleaning operation for the outer periphery of the upper cover plate is inefficient and requires a large amount of manpower, which makes it difficult for the operator to work for a long time. Utility Model Content

[0031] In a new energy vehicle battery pack production line, after the battery pack lower shell cover is assembled with the battery modules, an upper cover plate needs to be covered on it, and its function is to seal the battery pack. The upper cover plate is in the material area. An operator uses a special grasping device to grasp the upper cover plate to the preparation station. After the upper cover plate is placed at the preparation station, a cleaning agent is used to clean the gluing edge of the upper cover plate. After cleaning, the upper cover plate is transported to the gluing station through a conveyor line. When it reaches the gluing station, a gluing positioning mechanism will position the upper cover plate. After positioning, an industrial robot equipped with a glue gun applies a high-rigidity sealant along the edge of the upper cover plate. After gluing, the conveyor line will transport the upper cover plate to the removal station.

[0032] Currently, the cleaning operation efficiency of the outer periphery of the upper cover plate is low, and it requires a large amount of manpower, resulting in it being difficult for the operators engaged in this operation to work for a long time.

[0033] After research by the inventor, it is found that the existing cleaning of the outer periphery of the upper cover plate relies on the operator to go around the upper cover plate once. The operator needs to move around the upper cover plate while using a cleaning tool to clean the outer periphery of the upper cover plate. The on-site environment is complex, and the moving operator also needs to avoid other equipment and operators, which affects the cleaning efficiency of the operator. Moreover, the movement of the operator also consumes manpower, resulting in the fact that if the operator needs to work for a long time, the operator will be unable to work for a long time due to fatigue. Moreover, as the number of upper cover plates to be cleaned increases, the moving speed of the operator will also decrease, thereby further affecting the cleaning efficiency.

[0034] In view of this, the present utility model proposes an auxiliary cleaning mechanism and an assembly production line, aiming to solve the problem of how to improve the cleaning efficiency of the upper cover plate and reduce the manpower consumption.

[0035] Please refer to Figure 1 and Figure 2, in an embodiment of the present utility model, the auxiliary cleaning mechanism 100 includes a fixed frame 1, a lifting driving member 2, a rotating frame 3 and a suction cup assembly 4. The lifting driving member 2 is arranged on the fixed frame 1; the rotating frame 3 includes a rotating shaft 31 and a frame body 32 which are connected to each other. The rotating shaft 31 is rotatably installed on the fixed frame 1 and is slidably matched with the fixed frame 1. The lifting driving member 2 is in transmission connection with the rotating shaft 31 so that the lifting driving member 2 can drive the frame body 32 to move up and down relative to the fixed frame 1 through the rotating shaft 31; the suction cup assembly 4 is arranged on the side of the frame body 32 away from the rotating shaft 31, and the suction cup assembly 4 is used for adsorbing the workpiece.

[0036] The technical solution of the present utility model uses the auxiliary cleaning mechanism 100 to assist the operator in cleaning the outer periphery of the workpiece. When the workpiece needs to be cleaned, the suction cup assembly 4 adsorbs the workpiece. Since the rotating shaft 31 is slidably matched with the fixed frame 1, the lifting driving member 2 can drive the workpiece located on the frame body 32 to rise relative to the fixed frame 1 through the rotating shaft 31. The operator takes a cleaning tool to clean the outer periphery of the workpiece. Since the frame body 32 can rotate relative to the fixed frame 1 through the rotating shaft 31, the operator can rotate the workpiece while cleaning the outer periphery of the workpiece, saving the process of the operator walking around the workpiece once, thereby improving the cleaning efficiency of the workpiece and saving manpower. When the cleaning of the workpiece is completed, the lifting driving member 2 drives the rotating frame 3 to descend, and the suction cup assembly 4 releases the adsorption of the workpiece. The workpiece can be the upper cover plate of the battery pack. It should be noted that by setting the suction cup assembly 4 to adsorb the workpiece, the probability of the workpiece slipping relative to the frame body 32 during rotation and falling off the frame body 32 is reduced; by setting the lifting driving member 2 to lift the workpiece, the workpiece is separated from the conveying mechanism 201 for transporting the workpiece, avoiding scratches on the surface of the workpiece caused by the direct rotation of the workpiece relative to the conveying mechanism 201. It should also be noted that the lifting driving member 2 can be a cylinder or an electric cylinder.

[0037] In one embodiment, the auxiliary cleaning mechanism 100 further includes a travel switch. The workpiece includes a starting position and a completion position. The workpiece can be moved from the starting position to the completion position by the rotating frame 3. The travel switch can detect whether the workpiece is at the completion position. By setting the travel switch to assist in detecting whether the workpiece rotates to the completion position, before the workpiece rotates, the workpiece is at the starting position. As the workpiece rotates, the operator cleans the outer periphery of the workpiece. After the workpiece rotates a preset angle, the workpiece moves from the starting position to the completion position. At this time, the workpiece will contact and trigger the travel switch. If the travel switch is triggered, it means that the workpiece has rotated in place, which also means that the operator has completed the cleaning operation of the workpiece. And by setting the travel switch to detect the position of the workpiece after rotation, the workpiece can be rotated to a specified position after cleaning, so as to facilitate subsequent operations, avoiding the phenomenon that it is difficult to perform subsequent positioning and gluing of the workpiece because the workpiece is not in the completion position. For example, if the workpiece needs to be positioned after cleaning, the original positioning device is to contact the specified position of the workpiece to perform positioning. However, if the position of the workpiece changes after cleaning, the orientation of the specified position will also shift, resulting in the positioning device being unable to smoothly contact the specified position, which may cause the positioning device to be unable to smoothly position the workpiece.

[0038] In one embodiment, the auxiliary cleaning mechanism 100 further includes an indicator light. The travel switch is communicatively connected to the indicator light. When the workpiece is at the completion position, the indicator light emits light. By setting the indicator light to emit light after the workpiece rotates to the completion position, the operator is visually informed that the current workpiece has rotated a preset angle. Among them, the preset angle is generally 360°.

[0039] Please refer to Figures 1 to 3 , in one embodiment, the auxiliary cleaning mechanism 100 further includes a stop button 6. Both the stop button 6 and the travel switch are communicatively connected to the lifting drive member 2. By setting the stop button 6, after the operator completes the cleaning operation of the outer periphery of the workpiece, the operator can press the stop button 6, and the lifting drive member 2 will drive the rotating frame 3 to descend, so that the workpiece moves onto the conveying mechanism 201.

[0040] In one embodiment, the fixing frame 1 includes a fixing base 11 and a bearing 12. The bearing 12 is disposed on the fixing base 11. The rotating shaft 31 passes through the inner ring of the bearing 12. The rotating shaft 31 can slide axially along the inner ring of the bearing 12 and the rotating shaft 31 can also rotate relative to the fixing base 11 through the bearing 12. By providing the bearing 12, the rotating shaft 31 can rotate relative to the fixing base 11 through the bearing 12. It can be that the rotating shaft 31 and the bearing 12 are in spline fit to enable the rotating shaft 31 to slide relative to the bearing 12 and also enable the rotating shaft 31 to drive the inner ring of the bearing 12 to rotate relative to the outer ring, thereby realizing the rotation of the rotating shaft 31 relative to the fixing base 11. It can also be that the inner ring of the bearing 12 is provided with a chute extending axially along the bearing 12, and a slider is formed by the convexity on the outer wall of the rotating shaft 31. The slider is located in the chute so that the rotating shaft 31 can slide relative to the bearing 12 and also rotate relative to the fixing base 11.

[0041] According to an embodiment of the present invention, a through hole for the rotating shaft 31 to pass through can be provided on the fixing frame 1. The rotating shaft 31 is in clearance fit with the through hole, so that the rotating shaft 31 can slide and rotate relative to the through hole.

[0042] In one embodiment, the bearing 12 is a one-way bearing 12. By setting the bearing 12 as a one-way bearing, the operator can only rotate the workpiece in a specified direction.

[0043] In one embodiment, the suction cup assembly 4 includes a plurality of suction cups 41. The plurality of suction cups 41 are arranged at intervals, and the plurality of suction cups 41 are all disposed on the frame body 32. By providing a plurality of suction cups 41 to adsorb the workpiece, the reliability of adsorbing the workpiece is improved.

[0044] In one embodiment, the auxiliary cleaning mechanism 100 further includes a storage rack 7 for placing cleaning tools. By providing the storage rack 7 to place cleaning tools, it is convenient for the operator to pick up and place them. The cleaning tools can be cleaning liquid, cleaning cloth, etc.

[0045] Please refer to Figures 1 to 3 , the present invention also provides an assembly line 200, which includes a conveying mechanism 201 and the above-mentioned auxiliary cleaning mechanism 100. The conveying mechanism 201 is used to transport workpieces. The conveying mechanism 201 includes a cleaning position 202, and the fixing frame 1 is arranged corresponding to the cleaning position 202. The specific structure of the auxiliary cleaning mechanism 100 refers to the above embodiment. Since this assembly line 200 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0046] In one embodiment, the assembly line 200 further includes a workpiece detector and a start button 5. The start button 5 and the workpiece detector are both communicatively connected to the lifting drive member 2. The workpiece detector is configured to detect whether the workpiece is located at the cleaning position 202. By providing the workpiece detector to detect whether the workpiece has moved to the cleaning position 202, only after the workpiece has moved to the cleaning position 202 can the operator press the start button 5, and then the lifting drive member 2 will lift the workpiece, thus avoiding the situation where the operator accidentally touches the start button 5 when the workpiece has not reached the cleaning position 202, resulting in the lifting drive member 2 driving the rotating frame 3 to rise.

[0047] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
