Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a negative pressure detection tool for a battery negative pressure module. Background Art

[0002] During the production process of lithium batteries, they need to be oxidized and capacitated. The oxidization is to charge and discharge the cells of lithium batteries to activate the internal chemical substances, and the capacitation is to grade and screen the capacity of the cells. During the oxidization and capacitation process of lithium batteries, high-pressure gas is easily generated inside the cells, which will bulge the sides of the cells, so it is necessary to use negative pressure to extract the generated gas. When extracting gas through the negative pressure module, the injection port is usually used as the exhaust port. When excessive bubbles are discharged to the injection port through negative pressure suction, a certain amount of electrolyte will be pushed out. The electrolyte will form crystals at the suction nozzle of the negative pressure module and inside the negative pressure cup, causing the negative pressure module to leak and the pipeline to be blocked, which will cause the vacuum value to fail to reach the specified value and partially block the pipeline in the subsequent production. Therefore, it is necessary to regularly inspect the negative pressure module of the oxidization and capacitation equipment.

[0003] In the existing negative pressure detection tooling of the battery negative pressure module, a test channel for connecting the negative pressure nozzle for detection is provided, and the position of the test channel corresponds to the position of the liquid filling port of the battery to be tested. However, since the position of the test channel in the current negative pressure detection tooling cannot be adjusted, in order to adapt to batteries of different sizes, the chemical composition equipment on each storage location needs to pre-set the motion mechanism for driving the negative pressure module before the negative pressure detection is performed on the negative pressure module. The negative pressure detection tooling cannot be directly compatible with batteries of various sizes for detection, and the efficiency is low. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 7 The utility model provides a negative pressure detection tooling for a battery negative pressure module.

[0029] The negative pressure detection tooling of the battery negative pressure module includes a negative pressure detection unit and an adjustment component 300. The negative pressure detection unit includes a frame 100 and a plurality of test rods 200 arranged on the frame 100. The test rods 200 are provided with a plurality of test channels 210 in parallel. A vacuum digital display 220 is embedded on the front panel of the frame 100. The test channel 210 is used to communicate with the vacuum digital display 220 and an external negative pressure suction nozzle; the adjustment component 300 includes an adjustment screw 330, a first adjustment block 310 and a second adjustment block 320, the first adjustment block 310 is fixedly connected to the first base plate 110 of the frame 100, the second adjustment block 320 is fixedly connected to the second base plate 120, and the first base plate 110 is movably connected to the second base plate 120; the adjustment screw 330 is clamped with the first adjustment block 310, and the second adjustment block 320 is provided with an adjustment screw hole 340, and the adjustment screw 330 is screwed into the adjustment screw hole 340, and the rotation of the adjustment screw 330 causes the first adjustment block 310 to move and thereby drives the frame 100 away from or close to the second base plate 120.

[0030] Specifically, the negative pressure detection tooling of the battery negative pressure module of the utility model is installed in the tray storage position of the chemical fractionation equipment, the moving mechanism assembly is suspended on the top of the chemical fractionation equipment, and the moving part of the moving mechanism assembly is equipped with a negative pressure module with a negative pressure nozzle, the negative pressure detection tooling of the battery negative pressure module is located directly below the moving part of the moving mechanism assembly, and the negative pressure nozzle is in contact and connected with the test channel 210 in a one-to-one correspondence, so as to evacuate the negative pressure passage to form a negative pressure environment for detection. The frame 100 is a frame with an upper opening, and the test rods 200 are arranged in an array in the frame 100. One side of the test channel 210 on the test rod 200 can be connected to the vacuum digital display 220 through an air pipe, and the other side of the test channel 210 is used to connect to an external negative pressure nozzle, so as to detect the air pressure of the negative pressure nozzle through the vacuum digital display 220, and judge whether the negative pressure nozzle is leaking.

[0031] The upper opening of the test channel 210 on the test rod 200 corresponds to the liquid injection port of the batteries to be tested of different sizes. By adjusting the position of the test channel 210 on the test rod 200, it is compatible with the chemical composition equipment for testing the batteries to be tested of different sizes. When it is necessary to adjust the height of the frame 100 and thus adjust the height of the test rod 200, the staff can rotate the adjusting screw 330. At this time, the second adjusting block 320 and the second bottom plate 120 are fixed. The adjusting screw 330 rotates to cause the adjusting screw 330 to move up and down. Since the adjusting screw 330 is clamped with the first bottom plate 110 of the frame 100, the adjusting screw 330 is threadedly matched with the adjusting screw hole 340 of the second bottom plate 120, so that the adjusting screw 330 can drive the first bottom plate 110 of the frame 100 to move up and down, thereby realizing that the height of the test rod 200 in the frame 100 can be adjusted. For example, the adjusting screw 330 is rotated counterclockwise. Since the adjusting screw 330 is threadedly matched with the adjusting screw hole 340 of the second bottom plate 120, the adjusting screw 330 rises and drives the first bottom plate 110 of the frame 100 to rise, so that the height of the test rod 200 is increased to adapt to batteries of larger sizes. With such a configuration, the negative pressure detection tooling of the battery negative pressure module can be compatible with different sizes of batteries, thereby improving the compatibility of the negative pressure detection tooling of the battery negative pressure module with batteries of different sizes.

[0032] See also Figures 5 and 6, Further, the adjusting screw 330 includes a screw main body 331 and a clamping block 332 provided on the outer periphery of the screw main body 331. A clamping groove 334 is defined between the nut 333 of the screw main body 331 and the clamping block 332. The first adjusting block 310 is provided with a through hole 311 for the adjusting screw 330 to pass through. The first adjusting block 310 is provided with a ring rib 312 at the through hole 311, and the ring rib 312 is arranged in the clamping groove 334. In this way, by clamping the ring rib 312 of the first adjusting block 310 in the clamping groove 334 of the screw main body 331, when the screw main body 331 rotates and moves, it can drive the first adjusting block 310 to move, and the height of the adjusting frame 100 can be adjusted.

[0033] Continue to refer to Figures 5 and 6 , Further, the first adjusting block 310 includes a first connecting portion 313, a first bending portion 314 and a second bending portion 315 connected to both ends of the first connecting portion 313. The first bending portion 314 and the second bending portion 315 are both provided with first connecting holes 316 for bolts to pass through to install the first adjusting block 310 on the first bottom plate 110. The first connecting portion 313 is provided with a through hole 311, and the first connecting portion 313 is provided with a ring rib 312 at the through hole 311. The first connecting portion 313 is of a C-shaped structure. In this way, the first adjusting block 310 can be installed on the first bottom plate 110 by bolts. Of course, other fixing methods can also be used. For example, the first adjusting block 310 is fixed on the first bottom plate 110 by snap connection.

[0034] Continue to refer to Figures 5 and 6 , Further, the second adjusting block 320 includes a second connecting portion 321, a third bending portion 322 and a fourth bending portion 323 connected to both ends of the second connecting portion 321. The third bending portion 322 and the fourth bending portion 323 are both provided with second connecting holes 324 for bolts to pass through and be screwed on the second bottom plate 120. The second connecting portion 321 is of a C-shaped structure. In this way, the second adjusting block 320 can be installed on the second bottom plate 120 by bolts. Of course, other fixing methods can also be used. For example, the second adjusting block 320 is fixed on the second bottom plate 120 by snap connection.

[0035] Please refer to Figure 1 , 2 , 3 and Figure 7In order to enable the first base plate 110 to move relative to the second base plate 120, further, a plurality of locking assemblies 400 are connected between the first base plate 110 and the second base plate 120. The locking assembly 400 includes an adjusting column 410 and a locking member 420. The locking member 420 is formed with a column hole 421. The adjusting column 410 passes through the column hole 421 and can move along the axial direction of the column hole 421. Locking holes 422 are provided on both sides of the locking member 420. When the locking holes 422 on both sides are connected by bolts, the locking member 420 clamps the adjusting column 410. When it is necessary to adapt to batteries of different sizes, the staff needs to first loosen the bolts of the locking holes 422 on each locking member 420 so that the first base plate 110 can move relative to the second base plate 120, and then rotate the adjusting screw 330 so that the adjusting screw 330 drives the first adjusting block 310 to move and adjust the position of the test rod 200 on the frame 100 to adapt to batteries of different sizes. After the adjustment is completed, the locking holes 422 on both sides of the locking member 420 are locked with bolts, and the locking member 420 is closed to clamp the adjusting column 410, so that the first base plate 110 and the second base plate 120 remain stationary, thereby realizing the position adjustment of the test rod 200 on the frame 100.

[0036] See also Figure 7 Furthermore, the locking member 420 includes a first locking block 423 and a second locking block 424 connected to each other, and the first locking block 423 and the second locking block 424 are both provided with a locking hole 422. The first locking block 423 and the second locking block 424 can be integrally formed, and a bolt can pass through the locking holes 422 on the first locking block 423 and the second locking block 424 to connect and clamp the adjustment column 410, thereby supporting the test rod 200 on the frame 100.

[0037] See also Figure 4 In order to maintain the stability of the locking assembly 400 supporting the frame 100 , further, a plurality of locking assemblies 400 are respectively arranged at the corners of the first bottom plate 110 and the second bottom plate 120 .

[0038] Furthermore, the locking member 420 is made of a deformable material, such as a deformable iron material, or other metal materials with low hardness.

[0039] See also Figure 4 In order to facilitate the adjustment of the position of the first bottom plate 110 by the adjustment screw 330, the adjustment assembly 300 is further arranged at the middle position of the first bottom plate 110 and the second bottom plate 120. The position of the adjustment assembly 300 is not limited to the middle position of the first bottom plate 110 and the second bottom plate 120, and can also be arranged at other positions. By arranging the adjustment assembly 300 at the middle position of the first bottom plate 110 and the second bottom plate 120, the force can be uniformly applied.

[0040] See also Figure 1 To facilitate the adjustment of the adjusting screw 330, the first bottom plate 110 is further parallel to the second bottom plate 120. The first bottom plate 110 and the second bottom plate 120 are both arranged in a flat plate shape.
