Description

Technical Field

[0001] This utility model relates to the field of battery cell production technology, specifically a battery cell adhesive bonding tool. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the global lithium battery production scale continues to expand. How to reduce production line development costs, improve production line changeover speed, and increase production efficiency are the key challenges that lithium battery companies are currently focusing on solving.

[0003] In the lithium battery production process, to improve battery life and safety, aerogel or foam needs to be adhered to the surface of the cell as a shock-absorbing and cushioning material, while also serving as fireproofing and heat insulation. The placement of the aerogel and foam on the cell needs to be strictly controlled, with a positional tolerance of approximately ±1mm. Two main adhesion methods are used on production lines: automated equipment and manual application using fixtures. Automated adhesion typically uses a robot with a suction cup mechanism to pick up and adhere the foam; however, this method is costly and results in frequent alarms during production. The manual method uses a rectangular fixture placed over the cell, and the foam is then placed inside the fixture for precise positioning and adhesion.

[0004] Manual foam pasting using fixtures is widely used in low-cost production lines. Traditional pasting fixtures are square frames corresponding to individual battery cells. They are usually placed on the workbench on the production line and manually picked up for use. After pasting one battery cell, the fixture is removed and then installed on the next battery cell. After pasting all the battery cells in a tray, the fixture is removed and returned to the workbench on the production line for storage.

[0005] This method has the following disadvantages:

[0006] Frequent manual operations and complex movements increase the burden on production personnel, resulting in low production efficiency and affecting the production line's cycle time. The tooling is a separate unit, and each battery cell needs to be reinstalled with the tooling, resulting in poor consistency in the application of adhesive. The work clothes are repeatedly transferred and retrieved both online and offline, making them prone to loss or damage. Utility Model Content

[0007] The technical problem to be solved by this utility model is how to improve the efficiency of manual online battery cell film application.

[0008] This utility model solves the above-mentioned technical problems through the following technical means: A battery cell adhesive application fixture includes a stopper and an adhesive application limiting frame. The adhesive application limiting frame is pivotally connected to side A of the logistics line, and its free end can rotate to side B of the logistics line. Side A and side B are parallel. The stopper intermittently blocks the battery cell trays on the logistics line. The adhesive application limiting frame includes a limiting frame corresponding to the number of battery cells on the battery cell tray. This utility model rotatably sets an adhesive application limiting frame on the side of the logistics line. The stopper can temporarily block the flow of battery cells, and the limiting frame can be manually rotated before adhesive application. Multiple battery cells can be applied at once, with high speed and high precision.

[0009] Furthermore, the adhesive applicator is rotatably fixed to side A of the logistics line via a rotating shaft mechanism; the rotating shaft mechanism includes a rotating shaft and a mounting bracket; the rotating shaft is fixed to side A of the logistics line via the mounting bracket; the first side of the adhesive applicator is fixed to the rotating shaft mechanism, and the second side of the adhesive applicator parallel to the first side is a free end.

[0010] Furthermore, it also includes a stop member, which is fixed on side B of the logistics line, and the free end of the adhesive applicator is stopped by the stop member when it rotates to side B of the logistics line.

[0011] Furthermore, the adhesive-applying limiting frame includes a limiting plate and a fixing rod; the limiting plate has fixing rods on both sides perpendicular to the running direction of the logistics line, one end of the fixing rod is fixed to the rotating shaft, and the other end has a pin hole; the top of the stop is fixed with a pin that mates with the pin hole.

[0012] Furthermore, the mounting bracket includes a fixing block, a bearing seat, and a rotating shaft support; the fixing block is fixed to the frame of the logistics line; the bearing seat is fixed to the fixing block; the rotating shaft is fixed to the bearing seat via a bearing; and the rotating shaft support is sleeved on the end of the rotating shaft and fixed to the bearing seat.

[0013] Furthermore, the mounting bracket also includes a support plate, which is horizontally fixed to the fixing block and located below the bearing seat; the support plate is fixed with a vertical stop; the stop limits the maximum rotation angle of the rotating shaft support.

[0014] Furthermore, the support plate has screw holes, and screws are screwed into the screw holes to form the stop.

[0015] Furthermore, the mounting holes for the fixing block and the logistics line bracket are vertical oblong holes.

[0016] Furthermore, the stop includes a mounting plate; the mounting plate is fixed to the logistics line bracket; and the pin is fixed to the top of the mounting plate.

[0017] Furthermore, the mounting holes for fixing the mounting plate to the logistics line are vertical oblong holes.

[0018] The advantages of this utility model are: This invention features a rotating adhesive-applying limit frame on the side of the logistics line. The flow of battery cells can be temporarily blocked by a stopper. The limit frame can be manually rotated before adhesive is applied. Multiple battery cells can be applied at once, resulting in high speed and high precision.

[0019] The stop mechanism limits the downward pressure of the limiting plate, preventing damage to the battery cells. Furthermore, the engagement of pins and pin holes enables rapid positioning of the tooling during assembly and debugging, improving assembly efficiency.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model discloses a battery cell adhesive bonding fixture, which is installed on the logistics line 7, such as... Figure 1As shown, the actual production of a lithium battery module production line mainly involves four parts: logistics line 7, cell tray 5, cell 6, cell adhesive applicator, and stopper 4. Cell 6 is placed in cell tray 5, which flows along logistics line 7. When it reaches the workstation, it is stopped and positioned by stopper 4 on logistics line 7. Personnel pull handles 2-4 on the adhesive applicator, causing the adhesive applicator limiting fixture structure 2 to rotate around its axis and cover the cell 6 (e.g., ...). Figure 2 (As shown), then foam bonding is performed. This utility model is an integrated adhesive bonding fixture that can complete the adhesive bonding task of multiple battery cells in one go with a simple rotation. like Figure 2 As shown, the battery cell adhesive applicator in this embodiment includes: a blocker 4 and an adhesive applicator limiting frame 2. The adhesive applicator limiting frame 2 is pivotally connected to side A of the logistics line 7 via a rotating shaft mechanism 1, and its free end can rotate to side B of the logistics line 7; side A and side B are parallel; the blocker 4 intermittently stops the battery cell tray 5 on the logistics line 7; the adhesive applicator limiting frame 2 includes a limiting frame with the same number of battery cells 6 as the battery cell tray 5. The specific structure is as follows: The rotating shaft mechanism 1 includes a rotating shaft 1-8 and a mounting bracket. Both ends of the rotating shaft 1-8 are fixed to the frame of the logistics line 7 via the mounting bracket. The mounting bracket includes a fixing block 1-1, a support plate 1-2, a reinforcing rib 1-3, a support screw 1-4, a rotating shaft support 1-5, a bearing 1-6, a bearing seat 1-7, and a bushing 1-9. The fixing block 1-1, support plate 1-2, and bearing seat 1-7 are all plate-shaped structures. The lower half of the fixing block 1-1 has a vertical oblong hole for assembly with the support of the logistics line 7. The oblong hole allows adjustment of the height of the fixing block 1-1, thereby adjusting the height of the entire fixture. In this embodiment, the support plate 1-2 and the reinforcing rib 1-3 are connected by bolts and then installed onto the fixing block 1-1. The support plate 1-2 is horizontal and has screw holes. The support screw 1-4 is screwed into the support plate 1-2 through its bottom thread. The bearing seat 1-7 is fixed to the fixing block 1-1 by bolts and is located above the support plate 1-2. Bearing 1-6 is installed in the opening of bearing housing 1-7. Two bushings 1-9 are inserted into rotating shaft 1-8, and bearings 1-6 are inserted into both ends of rotating shaft 1-8. Rotating shaft supports 1-5 are fitted onto the ends of rotating shaft 1-8. Rotating shaft supports 1-5 are then tightened with bolts to rotatably fix rotating shaft 1-8 to bearing housing 1-7. The mounting bracket is installed on the support of logistics line 7 using a slider nut and bolts via fixing block 1-1. The adhesive applicator includes a limiting plate 2-3 and fixing rods 2-1. The limiting plate 2-3 is a rectangular plate structure with its long side aligned with the direction of movement of the material flow line 7. Multiple limiting frames for positioning the battery cells 6 are cut into it. There are two fixing rods 2-1, each bolted to both ends of the limiting plate 2-3 in the width direction and perpendicular to the direction of movement of the material flow line 7. The length of the fixing rods 2-1 is greater than the width of the limiting plate 2-3, so both ends of the fixing rods 2-1 extend a certain distance beyond the limiting plate 2-3. One end of the fixing rods 2-1 is bolted to the rotating shaft support 1-5, allowing the adhesive applicator to rotate around the rotating shaft 1-8. In this embodiment, a handle 2-4 is also installed at the free end of the limiting plate 2-3. The operator rotates the adhesive applicator 2-3 using the handle 2-4, causing the limiting plate 2-3 to cover the battery cells 6, and then applies the foam adhesive.

[0025] To increase the strength of the limiting plate 2-3, in this embodiment, mounting beams 2-2 are bolted to two sides of its long side. The two ends of the mounting beams 2-2 are also bolted to the fixing rod 2-1, thus forming an integral structure with the fixing rod 2-1, mounting beams 2-2, and limiting plate 2-3. This ensures the strength of the limiting plate while reducing the weight of the adhesive-coated limiting frame. Alternatively, the mounting position of the mounting beams 2-2 on the fixing rod 2-1 can be designed as an elongated hole, allowing adjustment of the front-to-back position and size of the limiting plate 2-3. In this embodiment, to ensure the accuracy of the downward pressure height of the adhesive application limit frame 2, a stop component 3 is also provided. The stop component 3 is fixed to side B of the logistics line 7 and includes a mounting plate 3-1. The mounting plate 3-1 also has an oblong hole and is fixed to the support of the logistics line 7. The height of the mounting plate 3-1 can be adjusted. The top of the mounting plate 3-1 can serve as the stop position for the adhesive application limit frame.

[0026] However, in order to facilitate positioning during assembly and debugging, this embodiment also has a pin 3-2 fixed on the top of the mounting plate 3-1, and a pin hole is opened at the free end of the fixing rod. The pin hole and the pin 3-2 cooperate to both stop the movement and accurately position the device during the assembly and debugging stage.

[0027] To keep the battery cell 6 on the logistics line 7, the stopper 4 of this application can be either an electrically operated telescopic stopper 4 or a manually operated stopper 4. To improve efficiency, this embodiment uses an electrically operated telescopic stopper 4, fixed below or to the side of the logistics line 7. It extends upwards (the logistics line 7 consists of multiple narrow conveyor belts with gaps between adjacent belts for the telescopic rod of the stopper 4 to extend and retract) or horizontally via electromagnetic induction, thereby temporarily stopping the flow of the battery cell 6 on the logistics line 7. The electrically operated telescopic stopper 4 is commercially available, and its specific structure will not be detailed here.

[0028] Working principle: When there is no production task, the tooling is in the open state (e.g., Figure 1As shown), the rotating shaft support 1-5 is supported on the support screw 1-4. The opening angle of the tooling can be adjusted by the depth of the support screw 1-4, ensuring that the handle 2-4 is within a reasonable operating range. The battery cell tray 5, carrying the battery cell 6, flows on the logistics line 7. When it reaches the workstation, it is stopped and positioned by the stopper 4 on the logistics line 7. The operator pulls the handle 2-4, causing the adhesive applicator limiter 2 to rotate around the shaft and cover the battery cell 6 (as shown). Figure 2 (As shown), then foam bonding is performed. The mounting parts of the fixing block 1-1, mounting plate 3-1, and logistics line 7 all have elongated holes, thus the overall height of the mechanism is adjustable to accommodate battery cells 6 of different thicknesses. The mounting beam 2-2 on the fixing rod 2-1 also has an elongated hole, so the front-to-back position and size of the limiting plate 2-3 can also be adjusted. The entire mechanism can be installed and fixed at any position on the logistics line 7, depending on the location where the pallet stops; therefore, this tooling mechanism has good compatibility.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
