[0030] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the utility model can be combined interchangeably without conflicting with each other.
[0031] Reference Figures 1 to 9 The utility model provides a liquid injection static device, including a static chamber 1, a fixture 3 and a conveying mechanism 2 arranged in the static chamber 1 for conveying the fixture 3, the fixture 3 is used to place a cup tray and drive the cup tray to be conveyed in the static chamber 1, and the cup tray is used to fix the battery that has been injected with electrolyte.
[0032] The two ends of the static chamber 1 are rotatably provided with chamber doors 11, and the static chamber 1 is provided with a chamber door driving device 10 for opening and closing the chamber door 11. The output end of the chamber door driving device 10 is connected to a rotating shaft 101, and the chamber door 11 is fixedly connected to the rotating shaft 101. In this embodiment, the chamber door driving device 10 uses a motor, and the rotation of the motor drives the rotating shaft 101 to rotate, and further drives the chamber door 11 to rotate, that is, the function of automatically opening and closing the chamber door 11 can be realized. When the jig 3 needs to be transported into the device, the chamber door 11 is opened by the chamber door driving device 10.
[0033] To ensure the stability of the closing of the chamber door 11, a chamber cover 12 is provided on the chamber door 11, and a plurality of protruding structures 121 are evenly distributed on the chamber cover 12. A clamp 13 is provided at the end of the static chamber 1, and a plurality of concave structures 130 that are evenly distributed and compatible with the protruding structures 121 are provided on the clamp 13.
[0034] The transmission mechanism 2 includes a bracket and a transmission component disposed on the bracket. In the present embodiment, the transmission component is provided with two groups, and the two groups of the transmission components respectively include a support plate, sprockets 230 disposed at both ends of the support plate, a chain 23 connecting the sprockets at both ends, and a chain driving device 20 for driving the chain 23. Specifically, a driving wheel is connected to the output end of the chain driving device 20, a driven wheel is disposed on the inner periphery of the sprocket, the driving wheel and the driven wheel are connected by a transmission chain, the sprocket 230 cooperates with the chain 23, and when the chain driving device 20 is working, the chain can be driven.
[0035] The chain 23 is provided with a plurality of blocks 25 and ratchets 251, the spacing between each two adjacent blocks 25 is equal to the length of the jig 3, and the bottom of the jig 3 is provided with a through hole 31 that cooperates with the ratchets 251. Since there are two groups of transmission components, the through holes 31 at the bottom of the jig 3 are also provided with two rows, and the spacing between the chains 23 of the two groups of the transmission components is equal to the spacing between the two rows of through holes 31.
[0036] During operation, when the jig 3 enters the static chamber 1, the front edge of the jig 3 is blocked by the block 25. With the transmission of the chain 23, the pawl 251 will extend into the through hole 31 under the jig 3 to drive the jig 3 to move. Furthermore, the inner wall of the through hole 31 is provided with an inner sleeve made of a flexible material, which can reduce the friction between the pawl 251 and the jig 3 and prevent the generation of dust. After the jig 3 completely enters the static chamber 1, the rear edge of the jig 3 is also blocked by the block 25. In order to facilitate the smooth transmission of the jig 3, a guide rail 21 is provided on the bracket, and a guide wheel 30 is provided at the bottom of the jig 3. The guide rail 21 is provided with two groups and is located on both sides of the transmission component. When the through hole 31 of the jig 3 cooperates with the pawl 251, the jig 3 can move on the guide rail 21 by relying on the guide wheel 30 at its bottom.
[0037] Combined with the above content, it can be seen that the friction between the fixture 3 and the guide rail 21, and the chain 23 and the support plate are all rolling friction. Compared with the conventional conveying method, rolling friction produces less metal dust, which can greatly avoid metal dust contaminating the electrolyte in the battery and improve the quality of the battery.
[0038] Furthermore, a shield 24 is provided on the outer periphery of the support plate, and the shield 24 is provided with a closed structure on the side away from the chain 23, and a limiting groove is provided on the side of the shield 24 facing the chain 23, and the chain 23 is limited in the limiting groove. The shield 24 can protect the chain 23, and can also have a certain isolation effect on the small amount of dust generated by the transmission of the chain 23, so as to prevent the dust from flying onto the jig 3 and ensure the production quality of the battery.
[0039] Furthermore, the bracket is provided with an adapter plate 26, and a waist-shaped hole 261 is provided on the adapter plate 26. A round shaft is provided in the middle of the sprockets 230 in the two groups of the transmission components, and both ends of the round shaft are restricted in the waist-shaped hole 261 on the adapter plate 26 through a floating bearing seat 28. The upper and lower sides of the floating bearing seat 28 are provided with a guide groove 280, and the adapter plate 26 is provided with a bearing seat positioning block 262. The bearing seat positioning block 262 is provided with a guide boss 2620 adapted to the guide groove 280. The floating bearing seat 28 is slidably provided on the adapter plate 26 through the bearing seat positioning block 262. When the position of the floating bearing seat 28 needs to be adjusted, its sliding relationship with the bearing seat positioning block 262 can play a guiding role.
[0040] Furthermore, a screw positioning seat 272 is provided on the adapter plate 26, an adjusting screw 27 is provided between the screw positioning seat 272 and the floating bearing seat 28, a rotating groove is provided on the floating bearing seat 28, one end of the adjusting screw 27 is rotatably limited in the rotating groove by a limiting nut 271, and the adjusting screw 27 and the positioning seat are locked by a locking nut 270. It can be understood that when the tightness of the chain 23 needs to be adjusted, the position of the floating bearing seat 28 in the waist-shaped hole 261 can be adjusted synchronously by rotating the adjusting screw 27, and when the adjustment is completed, the locking nut 270 on the adjusting screw 27 is locked so that the locking nut 270 is tightly attached to the screw positioning seat 272, thereby locking the position of the floating bearing seat 28.
[0041] The utility model also provides a battery production line, comprising the liquid injection and static device as described above.
