[0019] Figure 2 for Figure 1 A schematic diagram of the structure of the extrusion device of the aluminum shell battery extrusion leak tester;

[0021] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0022] Combination Figure 1 and Figure 2As shown, an aluminum shell battery extrusion leak tester 10 includes: a frame 100, an extrusion device 200 and a conveying device 300, the extrusion device 200 includes a transverse sliding plate 210, a rotating transverse plate 220, a loading fixture 230 and an extrusion push plate 240, the transverse sliding plate 210 is slidably set on the frame 100, the rotating transverse plate 220 is rotatably set on the transverse sliding plate 210, the loading fixture 230 is set on the rotating transverse plate 220, and the extrusion push plate 240 is slidably set at one end of the loading fixture 230; the conveying device 300 is set on one side of the frame 100, the conveying device 300 is used to place at least two aluminum shell batteries in the loading fixture 230, and the extrusion push plate 240 is used to extrude the aluminum shell batteries in the loading fixture 230.

[0023] It should be noted that the aluminum shell batteries to be tested are transported to the aluminum shell battery extrusion leak tester 10 through the conveying line, and the aluminum shell batteries to be tested are transferred and placed on the loading fixture 230 through the handling device 300. The loading fixture 230 is provided with a loading slot 231 for placing the aluminum shell batteries, and the extrusion push plate 240 is slidably set on one side of the loading slot 231. In this way, when each aluminum shell battery to be tested is arranged in a straight line and placed in the loading slot 231, the extrusion push plate 240 is pushed in the direction of the loading slot 231, so that each aluminum shell battery is close to each other and squeezed, thereby realizing the synchronous extrusion operation of each aluminum shell battery. When the extrusion push plate 240 moves to the set position, the rotating horizontal plate 220 rotates 90 degrees relative to the transverse sliding plate 210, so that each aluminum shell battery rotates synchronously. At this time, through the inspection of the inspector or CCD imaging processing, it is possible to quickly determine whether each aluminum shell battery has leakage, and the aluminum shell batteries with leakage can be marked and screened, thereby completing the batch extrusion side leakage operation of the aluminum shell batteries. In this embodiment, there are two extrusion devices 200, and the two extrusion devices 200 are arranged parallel to each other on the frame 100. In this way, through the sliding operation of the transverse sliding plate 210, one of the extrusion devices 200 is performing the extrusion leakage detection operation, and the other extrusion device 200 is moved to the conveying device 300 to perform the aluminum shell battery loading operation, thereby improving the efficiency of the overall leakage detection operation and making the overall leakage detection operation more coherent. The aluminum shell battery extrusion leak tester 10 of the present invention is capable of performing batch extrusion leak test operations on aluminum shell batteries by providing a frame 100, an extrusion device 200 and a conveying device 300, thereby effectively improving the overall production efficiency and ensuring the product quality of the aluminum shell batteries.

[0024] Combination Figure 1 and Figure 2As shown, the extrusion device 200 further includes a transverse driving module 250, which is connected to the transverse sliding plate 210, and is used to drive the transverse sliding plate 210 on the frame 100 to move closer to or away from the transport device 300. In this embodiment, the transverse driving module 250 is a servo motor transverse driving module, so that the transverse sliding plate 210 can be driven to slide laterally on the frame 100.

[0025] Furthermore, a first hinge portion 211 and a second hinge portion 212 are respectively provided at both ends of the transverse sliding plate 210, one end of the rotating horizontal plate 220 is hinged to the first hinge portion 211, and the other end of the rotating horizontal plate 220 is hinged to the second hinge portion 212, so that the rotating horizontal plate 220 can be rotated; for example, the first hinge portion 211 and the second hinge portion 212 are both rotating shaft structures, so that the two ends of the rotating horizontal plate 220 can be turned on the rotating shaft, thereby enabling the rotating horizontal plate 220 to be rotated.

[0026] In one embodiment, the extrusion device 200 further includes a rotating module 260, which is connected to the rotating horizontal plate 220, and is used to drive the rotating horizontal plate 220 to rotate relative to the transverse sliding plate. In this embodiment, the rotating module 260 is a rotating motor, so that the rotating horizontal plate 220 can be driven to rotate by the rotating motor, so that the material loading fixture 230 on the rotating horizontal plate 220 can be rotated, thereby facilitating the leakage observation of the extruded aluminum shell battery.

[0027] like Figure 2 As shown, the material loading fixture 230 is slidably disposed on the rotating horizontal plate 220, and a fixed baffle 232 is disposed on the side of the material loading slot 231 of the material loading fixture 230 away from the extrusion push plate 240, and the fixed baffle 232 is disposed parallel to the extrusion push plate 240.

[0028] It should be noted that the loading jig 230 is slidably set on the rotating horizontal plate 220, so that it is convenient for the transport device 300 to place the aluminum shell batteries, so that the transport device 300 has a larger operating space when performing the picking and placing operations; when the aluminum shell batteries are arranged and placed in the loading slot 231, the extrusion push plate 240 pushes the materials in the direction of the loading slot 231, so that each aluminum shell battery approaches the direction of the fixed baffle 232, and the position is limited by the fixed baffle 232, thereby making the overall aluminum shell battery extrusion operation more stable.

[0029] Furthermore, the extrusion device 200 also includes a pushing drive module 270, which is a motor screw drive structure, and the pushing drive module 270 is connected to the extrusion push plate 240. In this way, not only can the pushing of the extrusion push plate 240 be controlled, but also the moving position of the extrusion push plate 240 can be accurately controlled according to actual product testing requirements, thereby realizing the control of the extrusion force.

[0030] In one embodiment, a first silicone buffer block 241 is provided on one side surface of the extrusion push plate 240 close to the fixed baffle 232, and a second silicone buffer block 232a is provided on one side surface of the fixed baffle 232 close to the extrusion push plate 240. The first silicone buffer block 241 and the second silicone buffer block 232a are arranged in parallel. In this way, the first silicone buffer block 241 and the second silicone buffer block 232a can play a buffering role in the extrusion and pushing operation of the extrusion push plate 240, thereby preventing the corresponding aluminum shell battery from being worn during the pushing and extrusion process.

[0031] Furthermore, the extrusion device 200 also includes a leakage recovery tray 280, which is arranged at the bottom of the transverse slide 210, and the two side surfaces of the leakage recovery tray 280 extend to the outside of the transverse slide 210 respectively. In this way, when the rotating transverse plate 220 drives the loading fixture 230 to rotate, if the corresponding aluminum shell battery leaks, the flowing electrolyte will drip into the leakage recovery tray 280, so that the electrolyte can be recovered without causing pollution to the production environment.

[0032] like Figure 2 As shown, in order to accurately control the extrusion force of the aluminum shell battery and avoid test errors caused by excessive extrusion force, the extrusion device 200 also includes a plurality of position sensors 290, each of which is arranged at intervals on one side surface of the loading fixture 230, and the detection end of each position sensor 290 is respectively located in the loading slot 231, so that when the extrusion push plate 240 extrude and push each aluminum shell battery, each aluminum shell battery approaches each other under the action of the extrusion force, and thus moves to the corresponding position sensor 290. When each position sensor 290 senses the corresponding aluminum shell battery, it indicates that each aluminum shell battery is squeezed into place, thereby enabling the extrusion force of the aluminum shell battery to be accurately controlled to avoid damage to the aluminum shell battery caused by excessive extrusion force.

[0033] Combination Figure 1 and Figure 3 As shown, the transport device 300 includes a transport robot 310 and a transport clamp 320 , the transport robot 310 is connected to the transport clamp 320 , an air suction nozzle 321 is provided on the transport clamp 320 , and the holding end of the transport clamp 320 is an “L”-shaped structure.

[0034] It should be noted that the handling manipulator 310 is a transverse lifting manipulator in the prior art, which can drive the handling clamp 320 to move horizontally and lift, thereby being able to carry and transfer the aluminum shell battery. The handling clamp 320 is provided with a suction nozzle 321, and the suction nozzle 321 is a silicone nozzle, so that it can play an elastic buffering role in the clamping process of the handling clamp 320 to prevent the aluminum shell battery from being damaged by clamping, and the aluminum shell battery can be adsorbed and fixed by the vacuum adsorption operation of the suction nozzle 321, thereby reducing the clamping force of the handling clamp 320, preventing the aluminum shell battery from being damaged by clamping, and making the overall clamping and fixing of the aluminum shell battery more stable. Since the aluminum shell battery is generally a rectangular body structure, by setting the supporting end of the handling clamp 320 to an "L"-shaped structure, it can better match the shape of the aluminum shell battery, thereby making the clamping operation of the aluminum shell battery more stable.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
