[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 4 As shown, a soft-pack lithium-ion battery thickness test gauge is characterized in that it includes a base 1, the base 1 is provided with a test plate 2, side brackets 3 are provided on both sides of the base 1, a cross bracket 4 is provided between the two side brackets 3, a limiting roller 5 is provided between the two side brackets 3, and a spacing adjustment structure 6 is provided on the upper side of the cross bracket 4 for adjusting the spacing between the limiting roller 5 and the test plate 2 of the base 1.

[0024] The spacing adjustment structure 6 is used to control the position of the limiting roller 5. At this time, the limiting roller 5 moves up and down as a whole without offset, thereby ensuring the consistency of the spacing between the limiting roller 5 and the test plate 2, thereby ensuring the quality of the product during the inspection process and ensuring the consistency of the battery thickness.

[0025] At this time, in order to ensure that the limiting roller 5 will not deviate during the movement, in the present embodiment, fixing ears 51 are provided at both ends of the limiting roller 5, a transverse fixing plate 52 is provided between the two fixing ears 51, a guide rod 53 is provided on the upper side of the transverse fixing plate 52, the upper end of the guide rod 53 passes through the transverse bracket 4 to the upper side of the transverse bracket 4, a connecting plate 54 is provided on the upper ends of the two guide rods 53, and the spacing adjustment structure 6 is located on the outer side of the connecting plate 54, for controlling the up and down movement of the connecting plate 54. At this time, both ends of the limiting roller 5 are rotatably connected to the fixed ears 51 through bearings, thereby ensuring that the limiting roller 5 can rotate normally between the two fixed ears 51, and the two fixed ears 51 are connected by a transverse fixing plate 52, and the transverse fixing plate 52 is connected to the connecting plate 54 through a guide rod 53, and the spacing adjustment structure 6 acts on the connecting plate 54 to move the connecting plate 54, thereby moving the limiting roller 5, thereby adjusting the spacing between the limiting roller 5 and the test plate 2, at this time, ensuring that the connecting plate 54 does not shift when moving, can ensure that the limiting roller 5 does not shift when moving, and the connecting plate 54 is a plate structure with a certain area. When the direction of the external force remains unchanged, the moving process is relatively stable, thereby ensuring that the limiting roller 5 does not shift when adjusting its position.

[0026] Furthermore, a guide rail slider structure is provided between the side bracket 3 and the fixed ear 51, and the slider of the guide rail slider structure is perpendicular to the test plate 2. At this time, the guide rail slider structure is provided between the outer side of the fixed ear 51 and the inner side of the side bracket 3, so as to further ensure the stability of the movement of the fixed ear 51, thereby ensuring the stability of the spacing adjustment of the limiting roller 5 during use.

[0027] At this time, the guide rod 53 moves through the cross bracket 4. In order to ensure the stability of the movement of the guide rod 53, in this embodiment, the cross bracket 4 is provided with a linear bearing 55, and the guide rod 53 is connected to the cross bracket 4 at the position of the linear bearing 55.

[0028] The spacing adjustment structure 6 is used to adjust the position of the connecting plate 54. Therefore, in the present embodiment, the spacing adjustment structure 6 includes two upper fixing plates 61 on the side of the cross bracket 4. An upper top plate 62 is provided on the upper side of the two upper fixing plates 61. A screw 63 is passed through the upper fixing plate 61. One end of the screw 63 is connected to a lower wedge block 64 through a bearing. An upper wedge block 65 is provided on the lower side of the connecting plate 54. The inclined surfaces of the upper wedge block 65 and the lower wedge block 64 are in contact with each other. An elastic member 66 is provided between the connecting plate 54 and the upper top plate 62. The screw rod 63 is connected to the upper fixing plate 61 by threads, and the end of the screw rod 63 is connected to the lower wedge block 64 by a bearing. Therefore, the movement of the lower wedge block 64 can be controlled by turning the screw rod 63. At this time, the lower wedge block 64 and the upper wedge block 65 are abutted by the inclined surface. When the lower wedge block 64 moves laterally, the contact position with the upper wedge block 65 changes. Under the action of the elastic member 66, the upper wedge block 65 can be moved up and down.

[0029] In order to ensure that the lower wedge block 64 maintains a straight line during movement, in the present embodiment, a guide rail slider structure is provided between the lower wedge block 64 and the cross bracket 4, and the lower wedge block 64 slides along the guide rail direction in the guide rail slider structure. Through the guide rail slider structure, the lower wedge block 64 moves along a straight line direction, thereby ensuring that the lower wedge block 64 and the upper wedge block 65 will not be offset during the mutual movement, so that the upper wedge block 65 is always in contact with the lower wedge block 64, thereby ensuring the position stability of the upper wedge block 65 and the connecting plate 54 and the limiting roller 5.

[0030] The upper wedge block 65 and the lower wedge block 64 are in contact at the inclined surface position and move relative to each other at the inclined surface position. Therefore, in order to reduce the friction force when the two move relative to each other and make the movement more convenient, in this embodiment, the inclined surface of the lower wedge block 64 is provided with a groove, and a plurality of rolling wheels 67 arranged in parallel are arranged in the groove, and the inclined surface of the upper wedge block 65 is in rolling contact with the rolling wheels 67. A roller plate is fixed at the groove position by a fastener, and a plurality of rotatable rolling wheels 67 are arranged on the roller plate, so that the rolling wheels 67 are rotatably arranged at the inclined surface position of the lower wedge block 64, so that the contact between the upper wedge block 65 and the lower wedge block 64 becomes rolling contact, thereby reducing the friction force when the upper wedge block 65 and the lower wedge block 64 move relative to each other, so that the position of the limiting roller 5 can be adjusted more conveniently.

[0031] Since the position of the lower wedge block 64 is adjusted by the screw rod 63, after the lower wedge block 64 is adjusted to the corresponding position, in order to ensure the accuracy and stability of the test process, it is necessary to ensure that the gap height between the limit roller 5 and the test plate 2 remains unchanged. Therefore, in this embodiment, a fixing bar 68 is provided on the side of the lower wedge block 64, one end of the fixing bar 68 is fixed to the lower wedge block 64, and the other end of the fixing bar 68 is provided with a long waist-shaped groove in the same moving direction as the lower wedge block 64. The fixing bar 68 is fixed to the cross bracket 4 at the long waist-shaped groove position. Under the action of the fixing bar 68, the lower wedge block 64 can be fixed to the cross bracket 4, thereby fixing the position of the limit roller 5. When adjusting, loosen the fastener at the long waist-shaped groove position, and then move the lower wedge block 64, and then adjust the position of the limit roller 5.

[0032] Since the test is aimed at the thickness of the battery, the battery needs to be moved during the test. In order to facilitate the operation, in this embodiment, the test plate 2 is tilted and the limit roller 5 moves perpendicular to the test plate 2. The tilted setting of the test plate 2 allows the battery to slide down from a higher position of the test plate 2, and there is no need to move the battery manually, thereby improving production efficiency.

[0033] In order to ensure the accuracy during the test, the test board 2 is not modified, has high hardness, and is not easy to be damaged. Specifically, in this embodiment, a fixing groove is provided on the upper side of the base 1, and the test board 2 is arranged in the fixing groove. Limiting plates 21 are provided at both ends of the test board 2, and the limiting plates 21 are fixed to the upper side of the base 1 by fasteners. The limiting plates 21 at both ends of the test board 2 are pressed on the upper side of the test board 2, so as to fix the test board 2 in the fixing groove on the upper side of the base 1. In this way, a moving space for the battery to be tested is formed between the limiting plates 21 on both sides of the test board 2. At this time, the two limiting plates 21 are not only used to fix the test board 2, but also can form a channel for the product to be tested.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model 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 utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
