Description

Technical Field

[0001] This utility model relates to the technical field of packaging machine equipment, and in particular to a snap-fit ​​device for a battery cell packaging machine. Background Technology

[0002] In the field of photovoltaic cell production and processing, after the cells have undergone a series of processing steps, they need to be automatically packaged by a packaging machine. Among them, the box-locking process of loading the cells into cardboard boxes is one of the key links in the packaging process, which directly affects the efficiency of cell packaging and product yield. The current battery cell packaging machine's box-locking process typically employs the following operation: a conveyor mechanism precisely transports the battery cells to be boxed to a designated box-locking station, where a gripping mechanism clamps the box and drives it to be inverted from top to bottom onto the battery cells at that station, thus assembling the battery cells and the box. To ensure the stability of the battery cells during subsequent transportation and storage, and to prevent damage such as microcracks and edge chipping caused by shaking or collision due to excessive internal space in the box, the internal dimensions of the box in the current technology are usually strictly adapted to the external dimensions of the battery cells, so that the inner wall of the box can fit tightly against the side wall of the battery cells, thereby forming a reliable limiting and fixing effect. However, the above-mentioned adaptation design has defects in actual box-locking operation: Since there is almost no assembly gap between the inner wall of the cardboard box and the side wall of the battery cell, the cardboard box must be perfectly aligned with the battery cell during the inversion process. Once there is a slight positional deviation between the cardboard box and the battery cell in the horizontal direction, the inner edge of the cardboard box will make hard contact, friction or even collision with the corner or side wall of the battery cell. This contact will not only cause the cardboard box to fail to lock smoothly, resulting in the battery cell being "knocked off" and damaged; more seriously, the battery cell itself is fragile and has poor impact resistance. Collision or friction may cause scratches, microcracks or even direct breakage on its surface, which will greatly reduce the product yield and increase production costs. Utility Model Content

[0014] This application discloses a snap-fit ​​device for a battery cell packaging machine. (Refer to...) Figure 1 , Figure 2 and Figure 3 The battery cell packaging machine uses a snap-fit ​​device, which includes a frame 1. A linear module 11 is vertically mounted on the frame 1. A mounting frame 12 is connected to the movable seat of the linear module 11. A lifting cylinder 13 is vertically connected to the bottom of the mounting frame 12. A lifting plate 2 is connected to the piston rod of the lifting cylinder 13. The lifting plate 2 is horizontally mounted. A suction cup 21 is provided at each of the four corners at the bottom of the lifting plate 2. A cross plate 3 is fixedly connected to the bottom of the mounting frame 12. The cross plate 3 is located above the lifting plate 2. The lifting cylinder 13 is located at the center of the cross plate 3. A through hole is provided on the cross plate 3 for the lifting cylinder 13 to pass through. Four movable plates 31 are provided on the cross plate 3. The four movable plates 31 correspond to the four sides of the lifting plate 2. A hook plate 311 is connected to the bottom of the movable plate 31. The cross plate 3 is provided with a drive assembly 4 for driving the hook plate 311 to pull open the side panel of the paper box.

[0015] The drive assembly 4 is provided with four sets corresponding to the movable plate 31. The drive assembly 4 includes a first push cylinder 41 and a second push cylinder 42. The first push cylinder 41 is connected to the cross plate 3 and is arranged along the extension direction of the cross plate 3. A mounting plate 411 is connected to the piston rod of the first push cylinder 41. The second push cylinder 42 is connected to the mounting plate 411 and is arranged parallel to the first push cylinder 41. A connecting plate 421 is connected to the piston rod of the second push cylinder 42 and is connected to the movable plate 31.

[0016] The first push cylinder 41 can adjust the initial position of the hook plate 311. With the precise adjustment of the second push cylinder 42, it can adapt to paper boxes of different sizes and specifications, such as battery cell packaging paper boxes of different widths and lengths. There is no need to replace core components such as the hook plate 311 or the movable plate 31, which greatly improves the versatility of the device.

[0017] A fixed frame 22 is connected to the lifting plate 2. A fixed tube 221 is vertically connected to the fixed frame 22. A connecting tube 211 is connected to the suction cup 21. The connecting tube 211 is connected to a vacuum device through a hose. The connecting tube 211 passes through the fixed tube 221. A slider 2111 is connected to the connecting tube 211. The side wall of the slider 2111 slides against the inner wall of the fixed tube 221. A cap 2211 is connected to the top of the fixed tube 221. A limit block 2112 is connected to the end of the connecting tube 211 away from the slider 2111. The limit block 2112 abuts against the cap 2211. A spring 2113 is sleeved on the outside of the connecting tube 211. One end of the spring 2113 abuts against the slider 2111, and the other end abuts against the cap 2211.

[0018] When the suction cup 21 presses down to contact the paper box, the spring 2113 outside the connecting tube 211 acts as a buffer to prevent excessive pressure from damaging the paper box.

[0019] A fixing rod 23 is vertically connected to the lifting plate 2. The fixing rod 23 is located at each of the four corners of the lifting plate 2. A pressure block 231 is connected to the bottom of the fixing rod 23. The bottom of the pressure block 231 is higher than the bottom of the suction cup 21.

[0020] After the cardboard box is closed, the lifting cylinder 13 pushes the lifting plate 2 down, causing the pressure block 231 to press the cardboard box firmly.

[0021] A fixed plate 24 is connected to the lifting plate 2, and a displacement sensor 241 is connected to the fixed plate 24. A detection port is opened on the lifting plate 2, and the displacement sensor 241 is located directly above the detection port. The displacement sensor 241 monitors the position of the paper box in real time and assists in the timing of the action of each cylinder.

[0022] The implementation principle of the snap-box device for a battery cell packaging machine in this application is as follows: 1. Equipment preparation and initial calibration Check the status of each component of the device: ensure that the linear module 11, lifting cylinder 13, first push cylinder 41, and second push cylinder 42 are properly connected, the suction cup 21 is undamaged and has good airtightness, the hook plate 311 is not deformed, the displacement sensor 241 is aligned with the detection port and the signal transmission is normal, and the spring 2113 is not aged or deformed. Start the linear module 11 and move the mounting bracket 12 to the initial height; the piston rod of the lifting cylinder 13 retracts to the highest position, and the suction cup 21 is in a suspended state. 2. Adjustment of cardboard box specifications According to the size and specifications of the paper box to be fastened, the first push cylinder 41 is activated for coarse adjustment. The piston rod of the first push cylinder 41 drives the mounting plate 411, the second push cylinder 42 and the movable plate 31 to move along the extension direction of the cross plate 3, adjusting the four hook plates 311 to the corresponding positions on the outside of the paper box, so that the distance between the hook plates 311 and the side wall of the paper box is adapted to meet the expansion and support requirements of paper boxes of different specifications. After the coarse adjustment is completed, the first push cylinder 41 stops. Confirm that the initial position of the hook plate 311 is accurate, so that when the second push cylinder 42 is activated, the hook plate 311 can be accurately inserted into the inside of the cardboard box, preparing for the expansion action. 3. Cardboard box gripping and positioning The linear module 11 drives the mounting frame 12 to descend as a whole until the suction cup 21 at the bottom of the lifting plate 2 adheres to the top surface of the cardboard box. The external vacuum equipment is then activated, and air is extracted from the suction cup 21 through the connecting pipe 211 and the hose. The suction cup 21 then firmly adheres to the top of the cardboard box. After adsorption is completed, the linear module 11 drives the mounting frame 12 and the adsorbed paper box to rise to the preset height, so that the paper box is away from the initial placement position, leaving space for the hook plate 311 to extend in. 4. Hook plate 311 precisely extends into and expands the cardboard box. The second push cylinder 42 is activated for fine-tuning. The piston rod drives the connecting plate 421, the movable plate 31, and the hook plate 311 to move towards the paper box, so that the hook plate 311 is precisely inserted into the lower part of the paper box. The second push cylinder 42 stops. The lifting cylinder 13 is activated. The piston rod drives the lifting plate 2 and the adsorbed paper box to slowly descend, so that the paper box gradually covers the hook plate 311 inside. The second push cylinder 42 is activated again. The piston rod drives the hook plate 311 to move outward. The hook plate 311 fits against the inner side wall of the paper box and pulls the side plate outward to expand, so that the internal space of the paper box is temporarily expanded. The expansion range is preset according to the gap requirements between the battery and the paper box to eliminate the size interference problem when the box is fastened. 5. Fastening box operation and hook plate 311 reset After the expansion is completed, the second push cylinder 42 is activated in the reverse direction. The piston rod drives the hook plate 311 to move inward and away from the side plate of the cardboard box. Then, the lifting cylinder 13 drives the cardboard box to rise away from the hook plate 311. The second push cylinder 42 is activated to drive the hook plate 311 to move away from the bottom of the cardboard box to the initial position. Then, the lifting cylinder 13 lowers the cardboard box to smoothly cover the battery cells below. Since the cardboard box has been expanded, it does not need to be perfectly aligned and can be fastened smoothly to avoid collision with the battery cells.

[0023] After the cardboard box is properly engaged, the vacuum equipment stops working, the suction cup 21 releases the cardboard box, the lifting cylinder 13 drives the lifting plate 2 to descend, so that the pressure block 231 presses the cardboard box firmly, and then the lifting cylinder 13 drives the lifting plate 2 to rise and reset.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
