[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example 1:

[0035] See appendix Figure 1 This invention proposes a fixing fixture for battery quality testing, including a fixing panel 1, two linearly movable movable blocks 2 and a fixing block 3 mounted on the fixing panel 1.

[0036] When in use, the fixing fixture is used in conjunction with commonly used CCD vision inspection equipment. After the battery to be tested is fixed on the fixing fixture, the CCD vision inspection equipment is used to collect images of the fixed battery to be tested, and then compared and analyzed with preset images to determine whether there are any appearance defects in the fixed battery to be tested.

[0037] The specific image acquisition and analysis techniques are common knowledge and will not be elaborated upon here.

[0038] In this embodiment, since the movement trajectories of the two movable blocks 2 are perpendicular, and the space formed between the two movable blocks 2 and the fixed block 3 is used to place the battery to be tested, the enclosed space composed of the three structures has a free surface. Therefore, after the test is completed, the battery can be taken out from this side.

[0039] See appendix Figure 3It should be noted that the two movable blocks 2 are guided and slid along the length and width directions of the fixed panel 1, and the guide grooves 10 for the guided and sliding of the movable blocks 2 are arranged along the moving tracks of the movable blocks 2 on the fixed panel 1.

[0040] The fixed block 3 is arranged at the middle of one side of the fixed panel 1, one of the movable blocks 2 is arranged at the left side of the fixed panel 1, and the other movable block 2 is arranged at the lower side of the fixed panel 1 and is parallel to the fixed block 3. In this embodiment, the fixed block 3 is fixed to the fixed panel 1 by screws. Since one side of the enclosed space is exposed, there is no interference of other redundant structures, and the operator can conveniently take out the battery after the battery is detected and imaged, thereby improving the efficiency of the battery appearance detection to a certain extent.

[0041] Embodiment 2

[0042] This embodiment is based on embodiment 1, and the movable block 2 of embodiment 1 is further expanded. In this embodiment, two fixing modes of the movable block 2 are proposed. The first fixing mode is that a plurality of screw holes are arranged on the fixed panel 1, the screw holes are arranged at the groove bottoms of the guide grooves 10 (not shown in the figure), and the movable block 2 is fixed to the fixed panel 1 by screws.

[0043] In another mode, the bottom end of the movable block 2 is vertically provided with a slide rod 21 inserted into the guide groove 10, and the bottom end of each movable block 2 is vertically provided with two slide rods 21. The fixed panel 1 is provided with guide grooves 10 corresponding to the slide rods 21.

[0044] Since the overall size of the battery to be detected is different, the position of the movable block 2 can be adjusted according to the actual size of the battery to ensure that the movable block 2 is attached to the side end of the battery to be detected and is fastened to the fixed panel 1. The slide rod 21 is inserted into the guide groove 10 and synchronously slides with the movable block 2. The guide groove 10 is provided with protrusions 101 on the two sides of the groove along the arrangement direction of the protrusions 101, and the protrusions 101 are in clearance fit with the slide rods 21. The protrusions 101 are equally distributed on the two side surfaces of the groove 10. When the round head portions on both sides of the slide rod 21 abut on the protrusions 101, the round head portions are tightly attached between the two protrusions 101, thereby limiting the free sliding of the movable block 2 in the guide groove 10.

[0045] Although the size of the battery is various, the overall proportions are similar, that is, the same width or length. In order to quickly position the moving distance of the movable block 2, the fixed panel 1 is provided with scale lines 11 corresponding to the positions of the protrusions 101 on the upper end surface.

[0046] The above examples are only used to illustrate the technical solutions of the present application, and are not limiting; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced equivalently; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
