Description

Technical Field

[0001] The utility model relates to the technical field of battery diaphragms, and particularly relates to a film laminating machine for battery processing capable of preventing deviation during conveying. Background Technique

[0002] In the structure of a lithium battery, the diaphragm is one of the key inner components. The performance of the diaphragm determines the interface structure, internal resistance, etc. of the battery, directly affecting the characteristics such as the capacity, cycle, and safety performance of the battery. A diaphragm with excellent performance plays an important role in improving the comprehensive performance of the battery. Therefore, film laminating is required during the processing of lithium batteries;

[0003] The patent with the publication number CN217777779U discloses a battery diaphragm pressing and film laminating machine, including a processing table and a film running above the processing table. On both sides of the top wall of the processing table, receiving frames are symmetrically welded. Inner support shafts are rotatably connected to the inner sides of the two receiving frames. A main drum and a slave drum are respectively and fixedly sleeved on the two inner support shafts. The film is wound around the main drum and the slave drum. A motor is welded on the side wall of one of the receiving frames, and the output shaft of the motor is coaxially connected to the inner support shaft on the inner side of this receiving frame. An inverted U-shaped mounting frame is fixed on the processing table. An electric telescopic rod is welded at the center of the top wall inside the mounting frame. The telescopic end of the electric telescopic rod is fixedly welded with a film cutting box. Slicing knives are welded on the four sides of the bottom wall of the film cutting box. A spring and a film laminating pressing plate are arranged in the inner cavity of the film cutting box. For this battery diaphragm pressing and film laminating machine, the cut film is pressed downward along the vertical direction through the spring and the film laminating pressing plate, making it almost impossible for the film to shift. However, the following problems still exist in the actual use of this patent:

[0004] In the above device, each time, since the battery needs to be placed below the film, and the volume of the battery is smaller than that of the film, and the battery also needs to be located inside the knife groove and directly below the film cutting box, it ultimately leads to trouble in manually placing the battery, affecting the production efficiency. And as the roller gradually winds up the film, the diameter of the waste film roll gradually increases, resulting in a fixed starting duration of the motor each time, an increase in the length of the wound film, a decrease in the utilization rate of the film, and an increase in production costs.

[0005] A film laminating machine for battery processing capable of preventing deviation during conveying is proposed to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a film laminating machine for battery processing that can prevent deviation during conveying, so as to solve the problems in the above device mentioned in the background technology. Each time, since the battery needs to be placed under the film, and the volume of the battery is smaller than that of the film, and the battery also needs to be located inside the knife groove and directly below the film cutting box, ultimately resulting in trouble in manually placing the battery, affecting production efficiency. Moreover, as the roller gradually winds up the film, the diameter of the waste film roll gradually increases, resulting in a fixed startup duration for the motor each time, an increase in the length of the wound film, and thus a decrease in the utilization rate of the film and an increase in production costs.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: A film laminating machine for battery processing that can prevent deviation during conveying, including a processing table. On both sides of the processing table, two pairs of support frame plates are symmetrically and fixedly installed.

[0013] Preferably, the feeding component includes two pairs of driving frame plates and vertical plates symmetrically fixed on both sides of the support frame plates. The vertical plates are located between the driving frame plates and the support frame plates.

[0014] Preferably, between the two driving frame plates of the same pair, rotating rollers are symmetrically and rotatably installed up and down.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: This battery processing film laminating machine capable of preventing deviation in conveying avoids the situation of poor accuracy caused by manual calibration of the battery position, and at the same time avoids the situation where the battery position cannot be determined due to the obstruction of the film, ensuring the processing accuracy. The specific content is as follows:

[0018] 1. The driving motor enables the driving gear to drive the linkage gear ring to rotate, so that the control disk drives the curved groove to rotate, and forces the sliding column to move inside the curved groove. At the same time, in cooperation with the sliding block sliding in the straight groove, the bending push rod approaches the battery from the side and pushes the battery to the center of the knife groove, avoiding the situation of poor accuracy caused by manual calibration of the battery position, and at the same time avoiding the situation where the battery position cannot be determined due to the obstruction of the film, ensuring the processing accuracy.

[0019] 2. When installing the film roller, it is ensured that there is always a certain amount of redundant film between the rotary rollers on different sides. By starting the first motor and making the two motors rotate slowly in opposite directions, and using the connecting gear for transmission, the rotary rollers can pull the film at a fixed distance, avoiding waste of raw materials caused by excessive feeding.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-6 , the present invention provides a technical solution: a film laminating machine for battery processing that can prevent deviation during conveying, including a processing table 1. Two pairs of support frame plates 101 are symmetrically and fixedly installed on both sides of the processing table 1. A film roller 102 is rotatably installed between the two support frame plates 101 in the same pair. A center frame 103 is fixedly connected to the middle of the processing table 1. A film laminating device 104 is fixedly installed on the top of the center frame 103. A knife groove 105 is opened in the middle of the center frame 103; a take-up motor is fixedly installed at one end of a film roller 102, and the take-up motor can make the film roller 102 rotate, so that the processed waste film can be collected. There is a gap in the middle of the support frame plate 101, where the battery can be placed.

[0029] A positioning component 2 is arranged on the bottom surface of the processing table 1. The positioning component 2 includes a control panel 201 rotatably installed on the bottom surface of the processing table 1. A linkage gear ring 202 is fixedly connected to the outside of the control panel 201. A plurality of curved grooves 203 are opened in the middle of the control panel 201. A sliding column 206 is slidably connected in the curved groove 203;

[0030] Among them, a plurality of straight grooves 204 are opened in the middle of the processing table 1. A sliding block 205 is slidably connected in the straight groove 204. A bent push rod 207 is fixedly connected to the top of the sliding block 205. The top end of the sliding column 206 is fixedly connected to the bottom surface of the sliding block 205.

[0031] Among them, a feeding component 3 is arranged on the side of the processing table 1.

[0032] A housing 208 is fixedly connected to one side of the bottom surface of the processing table 1, and a driving motor 209 is fixedly connected to the interior of the housing 208. The output end of the driving motor 209 is upward and fixedly connected to a driving gear 210, and the driving gear 210 is meshed with the linkage gear ring 202; the driving motor 209 is a servo motor.

[0033] The straight grooves 204 are evenly distributed outside the knife groove 105 , and the control panel 201 is located directly below the knife groove 105 . The number of the straight grooves 204 and the number of the knife grooves 105 are the same, that is, four.

[0034] The material conveying assembly 3 includes two pairs of driving frame plates 301 and vertical plates 305 symmetrically fixed on both sides of the supporting frame plate 101, and the vertical plates 305 are located between the driving frame plates 301 and the supporting frame plates 101;

[0035] A rotating roller 302 is symmetrically installed between the two driving frame plates 301 of the same pair. The same end of the two rotating rollers 302 passes through the driving frame plate 301 and is fixedly connected with a connecting gear 304. The two connecting gears 304 are meshed and connected; the connecting gear 304 makes the upper and lower rotating rollers 302 rotate in opposite directions.

[0036] The two vertical plates 305 are rotatably connected to a rotating folding plate 306 on one side close to each other, and the other end of the rotating folding plate 306 is rotatably connected to a support shaft 307. The outside of the support shaft 307 is fixedly connected to a roller sleeve 308. Both ends of the support shaft 307 are rotatably connected to a support spring rod 309, and the other end of the support spring rod 309 is rotatably connected to the processing table 1; the support spring rod 309 can hold up the support shaft 307, and when the film descends, it rotates and contracts, so that the film remains horizontal and straight throughout the entire process.

[0037] A first motor 303 is fixedly connected to the outside of the driving frame plate 301 away from the connecting gear 304. The output end of the first motor 303 is fixedly connected to the rotating roller 302 located below. Two first motors 303, one for placing the film and the other for collecting the film, are started at the same time and run in opposite directions at the same speed. The first motor 303 is a servo motor.

[0038] Working principle: Before using this battery processing laminating machine with anti-biased conveying, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6As shown, when placing the battery, first place the battery from the notch of the support frame plate 101 into the middle of the knife groove 105, and then start the drive motor 209 to make the drive gear 210 drive the linkage gear ring 202 to rotate, so that the control disk 201 drives the curved groove 203 to rotate, and forces the sliding column 206 to move inside the curved groove 203. At the same time, cooperate with the sliding block 205 to slide in the straight groove 204, so that the bending push rod 207 approaches the battery from the side and pushes the battery to the center of the knife groove 105, avoiding the situation of poor accuracy caused by manual calibration of the battery position, and at the same time avoiding the situation where the position of the battery cannot be determined due to the obstruction of the film, ensuring the processing accuracy;

[0039] When installing the film roller 102, it is ensured that there is always a certain redundant film between the rotating rollers 302 on different sides. By starting the first motor 303 and making the two motors rotate slowly in the opposite direction, and transmitted by the connecting gear 304, the rotating roller 302 can draw the film at a fixed distance, avoiding waste of raw materials caused by excessive feeding;

[0040] Since the rotational speeds of the two first motors 303 are the same, there is always redundant film between the two rotating rollers 302. Then, through the support of the support spring rod 309 for the support shaft 307, the two roller sleeves 308 lift the film upward from both sides, and finally the redundant film can be straightened. Finally, when laminating the film, the film can descend and be cut in a straightened state, avoiding unnecessary rubbing between the inclined film and the laminating device 104.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
