[0027] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings.

[0028] As Figure 1 and Figure 2 shown, a liquid injection material-carrying jig 10 includes a tray frame 100 and a clamping component 200. A plurality of equally spaced clamping grooves 110 are formed on the tray frame 100. A jack 120 is formed on the bottom wall of each clamping groove 110. The clamping component 200 includes a plurality of strip supports 210 and a plurality of clamping members 220. The clamping members 220 are equally spaced on the outer side wall of the tray frame 100, and a part of the structure of each clamping member 220 extends into each jack 120. Each strip support 210 is detachably placed in the tray frame 100, and the strip supports 210 are spliced in sequence. When the end of the strip support 210 is inserted into the jack 120, the clamping member 220 clamps the strip support 210. A plurality of material placement grooves 2111 are formed on the strip support 210.

[0029] It should be noted that a plurality of material placement grooves 2111 are formed on each strip support 210, and each material placement groove 2111 is used to hold a battery. Further, a plurality of clamping grooves 110 are formed at the edge position of the tray frame 100, and the clamping grooves 110 are equally spaced. A through jack 120 is further formed on the bottom wall of each clamping groove 110. Further, a plurality of clamping members 220 are installed on the outer side wall of the tray frame 100, and the distance between the clamping members 220 is the same as the distance between the clamping grooves 110, so that a part of the structure of the clamping member 220 extends into the jack 120. In this way, when the strip supports 210 are sequentially placed in the tray frame 100 and one end of the strip support 210 is inserted into the jack 120, the clamping member 220 can clamp and fix the corresponding strip support 210. In this way, the strip supports 210 and the tray frame 100 form an integral structure. When it is necessary to remove the strip support 210 from the tray frame 100, an upward thrust is applied to the strip support 210 from the bottom, so that the strip support 210 is disengaged from the clamping of the clamping member 220. In this way, the liquid injection material-carrying jig 10 for the battery liquid injection process provided by the present application can realize the synchronous loading and unloading of a plurality of batteries by moving a single strip support 210, which can effectively improve the efficiency of battery loading and unloading. When electrolyte pollution occurs at a local position in the tray frame 100, only the strip support 210 at the corresponding position needs to be removed, and it is not necessary to remove all the batteries in the strip supports 210. Moreover, since the battery is protected by the strip support 210, it can prevent the staff from directly touching the battery and avoid the battery tab from being bent.

[0030] As Figure 1As shown, in one embodiment, the support bar 210 includes a support base 211 and two end blocks 212. The two end blocks 212 are respectively disposed at two ends of the support base 211. When the support bar 210 is placed in the tray frame 100, the end blocks 212 are inserted into the insertion holes 120, and each material placement groove 2111 is located on the support base 211.

[0031] It should be noted that the two end blocks 212 are respectively located at two ends of the support base 211. When the two end blocks 212 are respectively inserted into the corresponding two insertion holes 120, the tops of the two end blocks 212 fall into the card support grooves 110.

[0032] As Figure 2 shown, in one embodiment, the clamping member 220 includes a clamping seat 221, a clamping post 222 and a spring 223. The clamping seat 221 penetrates through the side wall of the tray frame 100 and extends into the insertion hole 120. The clamping post 222 is slidably disposed in the clamping seat 221. The spring 223 abuts against the clamping post 222 and the clamping seat 221 respectively. The spring 223 is used to push the clamping post 222 so that the end of the clamping post 222 passes through the clamping seat 221 and extends into the insertion hole 120.

[0033] It should be noted that the clamping seat 221 is installed on the outer side wall of the tray frame 100. The clamping post 222 passes through the clamping seat 221, and the spring 223 pushes the clamping post 222 and the clamping seat 221 respectively. Under the thrust of the spring 223, the clamping post 222 has a tendency to pass through the clamping seat 221 and extend into the insertion hole 120. In this way, the clamping post 222 can clamp the end block 212 of the support bar 210.

[0034] As Figure 1 shown, in one embodiment, a card slot 2121 is formed on a side surface of the end block 212 away from the support base 211 so that the end of the clamping post 222 is received in the card slot 2121.

[0035] In this way, after the end block 212 is inserted into the insertion hole 120, one end of the clamping post 222 is stuck in the card slot 2121, and the end block 212 can be withdrawn from the insertion hole 120 only when a thrust exceeding enough to compress the spring 223 is applied, effectively ensuring the structural stability between the support bar 210 and the tray frame 100.

[0036] In one embodiment, the length of the end block 212 is greater than the depth of the insertion hole 120. In this way, the end block 212 extends out from the lower end of the insertion hole 120, so that a thrust can be applied to the lower end of the end block 212 to facilitate the removal of the support bar 210 from the tray frame 100.

[0037] As Figure 3As shown, in one embodiment, a cross bar 300 is provided at the bottom of the tray frame 100, and the cross bar 300 is used to support each support bar 210. In this way, by the cross bar 300 bearing the middle positions of the support bars 210, the structural strength between the support bars 210 and the tray frame 100 can be improved, and the problem that the support bars 210 are bent due to their own gravity can be avoided. In one embodiment, the tray frame 100, the cross bar 300 and the support bars 210 are all made of plastic.

[0038] As Figure 1 shown, in one embodiment, a clearance groove 130 is respectively formed at both ends of the tray frame 100. In this way, it is convenient to carry the tray frame 100.

[0039] As Figure 1 shown, in one embodiment, a plurality of upper support columns 410 are provided on the top surface of the tray frame 100, and a plurality of lower support columns 420 are provided on the bottom surface of the tray frame 100, and each upper support column 410 and each lower support column 420 are aligned in one-to-one correspondence.

[0040] It should be noted that the positions of each upper support column 410 and each lower support column 420 correspond to each other. In one embodiment, both the upper support columns 410 and the lower support columns 420 are provided with four. In this way, through the provided upper support columns 410 and lower support columns 420, a plurality of tray frames 100 can be stacked. Specifically, for any two tray frames 100, the lower support columns 420 of one tray frame 100 are respectively docked with the upper support columns 410 of the other tray frame 100, so that the two tray frames 100 can be stacked.

[0041] As Figure 1 and Figure 4 shown, in one embodiment, a positioning boss 430 is provided at the top of the upper support column 410, and a positioning groove 421 adapted to the positioning boss 430 is formed at the bottom of the lower support column 420.

[0042] In this way, when two tray frames 100 are stacked, the positioning boss 430 can be adaptively inserted into the positioning groove 421 to ensure reliable stacking and fixing of the two tray frames 100.

[0043] As Figure 2 and Figure 4 shown, in one embodiment, a clamping block 500 is further provided on the outer side wall of the tray frame 100, and each clamping seat 221 abuts against the clamping block 500, so that the clamping block 500 and the tray frame 100 jointly clamp each clamping seat 221.

[0044] It should be noted that since multiple clamping members 220 need to be fixed on the outer side wall of the tray frame 100, in order to reduce the installation workload of the clamping members 220, a clamping block 500 is provided. Specifically, the clamping block 500 is fixedly locked on the outer side wall of the tray frame 100 by screws, so that the clamping block 500 clamps and fixes each clamping seat 221 on the outer side wall of the tray frame 100. In one embodiment, two oppositely distributed convex blocks are provided on the outer side wall of the clamping seat 221, and the convex blocks are abutted against the outer side wall of the tray frame 100, and then the clamping block 500 presses the convex blocks, so that the clamping seat 221 is reliably fixed on the outer side wall of the tray frame 100.

[0045] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
