[0026] In order to elaborate in detail the technical content and structural features of the present utility model, the following further description is made in conjunction with the embodiments and with reference to the drawings.

[0027] Please refer to Figure 1 and Figure 2 ; the battery clamp 100 of the present utility model can be applied to the battery inkjet occasion, clamping the battery before inkjet to prevent the battery from moving around during the inkjet process on its surface, thereby ensuring the inkjet quality on the surface of the battery.

[0028] Figure 4 Combined with Figure 4 again, the battery clamp 100 of the present utility model includes a frame body 10 and clamping units 20. A supporting structure 11 for supporting the battery is provided on the frame body 10. And the clamping units 20 are two arranged along the X - axis direction to meet the requirement that the battery clamp 100 of the present utility model can clamp two batteries at a time. Obviously, according to actual needs, the number of the clamping units 20 can also be one, three or four, etc., so it is not limited Figure 1 and Figure 2 as shown.

[0029] Among them, the clamping unit 20 includes a first sliding vertical frame 21, a second sliding vertical frame 22, a first sliding driver 23, a second sliding driver 24, a third sliding vertical frame 25, a third sliding driver 26 and a fixed vertical frame 27. The first sliding vertical frame 21 and the second sliding vertical frame 22 are slidably arranged on the frame body 10 along the X-axis direction. The first sliding vertical frame 21 is located beside one side of the supporting structure 11 separated in the X-axis direction. A first pressing member 21a and a first buffer 21b protruding along the X-axis direction from the first sliding vertical frame 21 are assembled on the first sliding vertical frame 21. The first buffer 21b is also aligned with the frame body 10 to meet the requirement that the first buffer 21b following the sliding of the first sliding vertical frame 21 can be pushed and compressed by the frame body 10. The second sliding vertical frame 22 is located beside the opposite side of the supporting structure 11 separated in the X-axis direction. A second pressing member 22a for clamping and cooperating with the first pressing member 21a and a second buffer 22b protruding along the X-axis direction from the second sliding vertical frame 22 are provided on the second sliding vertical frame 22. The second buffer 22b is also aligned with the frame body 10 to meet the requirement that the second buffer 22b following the sliding of the second sliding vertical frame 22 can be pushed and compressed by the frame body 10. The third sliding vertical frame 25 is located beside one side of the supporting structure 11 separated in the Y-axis direction. The third sliding vertical frame 25 can slide along the Y-axis direction. A third pressing member 25a is assembled on the third sliding vertical frame 25. The fixed vertical frame 27 is fixed to the frame body 10. The fixed vertical frame 27 is located beside the opposite side of the supporting structure 11 separated in the Y-axis direction. A fourth pressing member 27a for clamping and cooperating with the third pressing member 25a is assembled on the fixed vertical frame 27 to meet the requirement of clamping the battery by the fourth pressing member 27a and the third pressing member 25a from the Y-axis direction.

[0030] The output end 231 of the first sliding driver 23 is assembled and connected to the first sliding vertical frame 21 to meet the requirement of driving the first sliding vertical frame 21 to reciprocate along the X-axis direction by the first sliding driver 23. The output end 241 of the second sliding driver 24 is assembled and connected to the second sliding vertical frame 22 to meet the requirement of driving the second sliding vertical frame 22 to reciprocate along the X-axis direction by the second sliding driver 24. The output end 261 (see Figure 8 ) of the third sliding driver 26 is assembled and connected to the third sliding vertical frame 25 to meet the requirement of driving the third sliding vertical frame 25 to reciprocate along the Y-axis direction by the third sliding driver 26.

[0031] Therefore, under the driving of the first sliding frame 21 by the first sliding driver 23 and the driving of the second sliding frame 22 by the second sliding driver 24, the first pressing member 21a and the second pressing member 22a clamp or release the battery supported by the clamping support structure 11 in the X-axis direction; under the driving of the third sliding frame 25 by the third sliding driver 26, the third pressing member 25a and the fourth pressing member 27a clamp or release the battery supported by the clamping support structure 11 in the Y-axis direction; thereby realizing the bilateral positioning of the battery. Accurate, further ensuring the accuracy; and in the process of the first pressing member 21a and the second pressing member 22a clamping the battery, since the first buffer 21b slides following the first sliding stand 21 and the second buffer 22b slides following the second sliding stand 22, the first buffer 21b and the second buffer 22b are pushed and compressed by the frame 10, thereby ensuring the sliding consistency of the first pressing member 21a and the second pressing member 22a through the consistency of the compression stroke of the first buffer 21b and the second buffer 22b by the frame 10. It should be noted that when there are two clamping units 20, at this time, each clamping unit 20 corresponds to the supporting structure 11 and the cross frame 10b, the magnetic structure 13 and the positioning structure 14 described below, and the status is shown in FIG. Figure 3 More specifically, as follows:

[0032] like Figures 1 to 4 As shown, as an example, the frame 10 includes a rail 10a extending along the X-axis direction and a cross frame 10b spanning the rail 10a along the Y-axis direction, and the cross frame 10b is located between the first sliding frame 21 and the second sliding frame 22 along the X-axis direction. The supporting structure 11 is located on the cross frame 10b, and the first sliding frame 21 and the second sliding frame 22 are slidably arranged on the rail 10a; this design makes the battery clamp 100 of the present invention more compact, minimizes the overall size of the battery clamp 100 of the present invention as much as possible, and reduces the requirements for the production environment space. At this time, the first buffer 21b and the second buffer 22b are aligned with the cross frame 10b, and the cross frame 10b pushes the first buffer 21b and the second buffer 22b to compress. Specifically, in Figures 1 to 4 In the example, the rails 10a are two rails separated from each other along the Y-axis direction, the first sliding drive 21 is located in the gap 12 between the rails 10a, and the second sliding drive 22 is located outside the gap 12 between the rails 10a. The second sliding drive 22 is also arranged side by side with the rails 10a. Such a design can further make the battery clamp 100 of the present invention more compact, further reduce the overall size of the battery clamp 100 of the present invention, and further reduce the requirements for the production environment space. In addition, the cross frame 10b is a gantry structure to ensure that the cross frame 10b is reliably suspended above the rails 10a. More specifically, in Figures 1 to 4Among them, as an example, the first sliding driver 23, the second sliding driver 24, and the third sliding driver 26 can be cylinders, hydraulic cylinders, electric push rods, etc.

[0033] As Figure 6 shown, as an example, the first pressing member 21a can telescopically slide, such a design enables the first pressing member 21a to have a flexible buffering function when pressing the battery, avoiding hard pressing of the battery by the first pressing member 21a, thereby providing an effective protection for the battery. Specifically, in Figure 6 it, as an example, the first pressing member 21a includes a cylinder body 211 fixed on the first sliding vertical frame 21, a spring 212 and a pressing head 213 placed inside the cylinder body 211; the spring 212 elastically abuts against the cylinder body 211 and the pressing head 213, and the pressing head 213 also extends out of the cylinder body 211; to simplify the structure of the first pressing member 21a and also make the buffering performance of the first pressing member 21a better. More specifically, in Figure 6 it, as an example, a limiting structure 214 is provided on the pressing head 213, and a matching limiting structure 215 is correspondingly provided on the cylinder body 211. The matching limiting structure 215 blocks and limits with the limiting structure 214 when the pressing head 213 slides a preset distance in the direction away from the cylinder body 211, to prevent the pressing head 213 from accidentally falling off the cylinder body 211. It should be noted that in combination with Figures 1 to 5 , as an example, the number of the first pressing members 21a is four, and they are arranged in a rectangular array. Correspondingly, the number of the second pressing members 22a is also four. Each second pressing member 22a is aligned with a corresponding first pressing member 21a along the X-axis direction; obviously, according to actual needs, the numbers of the first pressing members 21a and the second pressing members 22a can also be other numbers, so it is not limited by Figures 1 to 4 shown.

[0034] As Figure 8 shown, as an example, the third pressing member 25a can telescopically slide, such a design enables the third pressing member 25a to have a flexible buffering function when pressing the battery, avoiding hard pressing of the battery by the third pressing member 25a, thereby providing an effective protection for the battery. Specifically, in Figure 8 it, as an example, the third pressing member 25a includes a cylinder body 251 fixed on the third sliding vertical frame 25, a spring 252 and a pressing head 253 placed inside the cylinder body 251. The spring 252 elastically abuts against the cylinder body 251 and the pressing head 253, and the pressing head 253 also extends out of the cylinder body 251; to simplify the structure of the third pressing member 25a and also make the buffering performance of the third pressing member 25a better. More specifically, in Figure 8Among them, as an example, a limiting structure 254 is provided on the top pressing head 253, and a matching limiting structure 255 is correspondingly provided on the cylinder body 251. When the top pressing head 253 slides away from the cylinder body 251 to a preset distance, the matching limiting structure 255 blocks and limits the limiting structure 254 to prevent the top pressing head 253 from accidentally falling off the cylinder body 251. It should be noted that in combination with Figures 1 to 4 and Figure 7 , as an example, the number of the third top pressing members 25a is two. Correspondingly, the number of the fourth top pressing members 27a is also two. Each fourth top pressing member 27a is aligned with a corresponding third top pressing member 25a along the Y-axis direction; obviously, according to actual needs, the numbers of the third top pressing members 25a and the fourth top pressing members 27a can also be other numbers, so it is not limited by Figures 1 to 4 and Figure 7 shown.

[0035] As Figure 4 shown, as an example, a magnetic attraction structure 13 and a positioning structure 14 are provided on the cross beam 10b beside the supporting structure 11, so as to facilitate the installation and disassembly operations of the matching ink receiving cartridge on the cross beam 10b by means of the magnetic attraction structure 13 and the positioning structure 14. Specifically, in Figure 4 , as an example, the magnetic attraction structure 13 and the positioning structure 14 are respectively arranged beside the two sides of the supporting structure 11 separated in the Y-axis direction to increase the magnetic attraction stability reliability and positioning accuracy between the ink receiving cartridge and the cross beam 10b. In addition, the supporting structure 11 protrudes upward from the cross beam 10b, the positioning structure 14 is a positioning pin protruding upward from the cross beam 10b, and the magnetic attraction structure 13 is a magnet buried in the cross beam 10b, but it is not limited thereto.

[0036] Compared with the prior art, by means of the arrangement of the first buffer 21b and the second buffer 22b, during the clamping process of batteries of different sizes, the compression strokes of the first buffer 21b that follows the first sliding upright frame 21 and is compressed by the frame body 10 and the second buffer 22b that follows the second sliding upright frame 22 and is compressed by the frame body 10 are consistent, so that the clamping centers of the first top pressing member 21a and the second top pressing member 22a in the X-axis direction do not change with the change of the battery size. Therefore, the battery clamping accuracy is ensured under the condition of being compatible with batteries of different sizes, thus creating good conditions for ensuring the battery inkjet quality. Moreover, since the battery fixture 100 of the present invention can be compatible with batteries of different sizes, it has universality and flexibility.

[0037] It should be noted that although the clamping unit 20 is described in the specific implementation manner as including a first sliding upright frame 21, a second sliding upright frame 22, a first sliding driver 23, a second sliding driver 24, a third sliding upright frame 25, a third sliding driver 26, and a fixed upright frame 27, however, according to actual needs, in other embodiments, the third sliding upright frame 25, the third sliding driver 26, and the fixed upright frame 27 can be deleted, so it is not limited to what is shown in the drawings.

[0038] The above-disclosed are only the preferred examples of the present utility model, and the scope of rights of the present utility model cannot be limited thereby. Therefore, all equivalent changes made according to the claims of the present utility model fall within the scope covered by the present utility model.
