In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] The blister tray structure provided in this embodiment is used for packaging and placing the battery cover plate, and can position and fix the battery cover plate; and can avoid the pole columns of the battery cover plate from being scratched or damaged.

[0030] Specifically, as Figures 1 to 4As shown, the structure of the blister tray includes a tray body 100, and a plurality of receiving grooves 110 are provided on the upper end surface of the tray body 100. The shape of the receiving groove 110 is adapted to the shape of the battery cover plate, and the battery cover plate can be placed in the receiving groove 110. The lower plastic of the battery cover plate abuts against the bottom of the receiving groove 110, and the side wall of the battery cover plate abuts against the side wall of the receiving groove 110. An avoidance groove 120 is provided at the outer bottom wall of the receiving groove 110 on the lower end surface of the tray body 100. The avoidance groove 120 is recessed towards the upper end surface of the tray body 100. When a plurality of blister tray structures with battery cover plates are stacked vertically and facing each other, among two adjacent blister tray structures, the two battery cover plates in the two facing receiving grooves 110 are directly opposite to each other. The end surface of the encapsulation ring of the battery cover plate located in the lower layer abuts against the outer bottom wall of the receiving groove 110 located in the upper layer, and the pole column in the encapsulation ring located in the lower layer can extend into the avoidance groove 120 of the tray body 100 located in the upper layer, so as to avoid the upper end surface of the pole column from contacting the outer bottom wall of the receiving groove 110 located in the upper layer.

[0031] Based on the above design, the structure of the blister tray includes a tray body 100, and a plurality of receiving grooves 110 are provided on the upper end surface of the tray body 100. The lower plastic of the battery cover plate abuts against the bottom of the receiving groove 110, and the side wall of the battery cover plate abuts against the side wall of the receiving groove 110. The receiving groove 110 is used to place the battery cover plate, position and fix the battery cover plate, and protect the battery cover plate during packaging, so as to avoid abnormal situations such as collision, sliding, and falling of the battery cover plate when handling the blister tray structure with the battery cover plate, resulting in damage to the battery cover plate. When a plurality of blister tray structures with battery cover plates are stacked vertically and facing each other, among two adjacent blister tray structures, the two battery cover plates in the two facing receiving grooves 110 are directly opposite to each other. The end surface of the encapsulation ring of the battery cover plate located in the lower layer abuts against the outer bottom wall of the receiving groove 110 located in the upper layer, so as to avoid the battery cover plate located in the lower layer from falling out of the receiving groove 110. An avoidance groove 120 is provided at the outer bottom wall of the receiving groove 110 on the lower end surface of the tray body 100. The pole column in the encapsulation ring located in the lower layer can extend into the avoidance groove 120 of the tray body 100 located in the upper layer, so as to avoid the upper end surface of the pole column from contacting the outer bottom wall of the receiving groove 110 located in the upper layer, thereby avoiding the end surface of the pole column from being scratched and affecting the appearance; at the same time, since the encapsulation ring is stressed to support the blister tray structure in the upper layer, the pole column is prevented from being crushed, and the encapsulation ring can also play a buffering role, which can further protect the battery cover plate.

[0032] Further, a boss structure is convexly provided on the inner bottom wall of the receiving groove 110, and the clearance groove 120 is located in the boss structure, which avoids the need for the size of the clearance groove 120 to cause the thickness of the tray body 100 to be too large, not only increasing the weight of the tray body 100 but also increasing the stacking height of the plastic suction tray structure. That is, by providing the boss, only a relatively large thickness of the tray column can be satisfied at the position of the clearance groove 120. Further, the boss structure is cylindrical and is adapted to structures such as the pole column and the encapsulation ring, reducing the volume of the boss structure. Of course, the boss structure can also be square, triangular, trapezoidal, etc., and the present utility model does not make specific limitations thereon.

[0033] It should be noted that the number of the receiving grooves 110 is the same as the number of the pole columns on the battery cover plate, and the internal shape of the receiving groove 110 is adapted to the shape of the part of the corresponding pole column exposed from the encapsulation ring.

[0034] Continuing as Figure 1 and Figure 3 shown, the number of the receiving grooves 110 on each tray body 100 is multiple, and the multiple receiving grooves 110 are arranged at intervals in sequence along the first direction, and the first direction is the width direction of the battery cover plate. By providing multiple receiving grooves 110, the plastic suction tray structure can package and place more battery cover plates, reducing costs. Since the battery cover plate is generally in a rectangular structure, arranging the receiving grooves 110 along the width direction of the battery cover plate improves the space utilization rate of the plastic suction tray structure.

[0035] In this embodiment, the plastic suction tray structure is generally in a square structure.

[0036] Further, a slotted groove 130 is provided between every two adjacent receiving grooves 110, and the slotted groove 130 communicates with the two adjacent receiving grooves 110, facilitating the taking and placing of the battery cover plate from the plastic suction tray structure.

[0037] For the convenience of setting the slotted groove 130 and to avoid scratching the hand, the inner wall of the slotted groove 130 is arc-shaped.

[0038] In order to keep the battery cover plate balanced when taking and placing the battery cover plate, there are two slotted grooves 130 between every two adjacent receiving grooves 110, and the two slotted grooves 130 are arranged at intervals along the second direction, and the second direction is the length direction of the battery cover plate.

[0039] Continuing as Figure 1 、 Figure 2 and Figure 3 shown, a positioning card slot 140 is provided on the outer periphery of the upper end surface of the tray body 100, facilitating the positioning of the plastic suction tray structure when handling the plastic suction tray structure.

[0040] In this embodiment, the tray body 100 of the plastic suction tray structure is integrally formed, which is convenient for processing and at the same time improves the overall structural strength of the tray body 100.

[0041] Furthermore, for better effect, the tray body 100 is made of plastic and integrally processed by an injection molding process, which is convenient for processing and reduces production costs.

[0042] To reduce the overall weight of the plastic suction tray structure, the tray body 100 is a sheet structure, and the receiving groove 110 is formed by a groove body that is recessed downward from the sheet structure at the lower end surface of the protruding sheet structure. For example, by means of injection molding, stamping and bulging, etc.

[0043] Since the tray body 100 is a sheet structure and has a relatively small thickness, after placing multiple battery covers on the tray body 100, the weight increases, and when handling the tray body 100, the non-receiving groove 110 part of the sheet structure is prone to deformation. Therefore, reinforcing ribs 150 are provided on the lower end surface of the sheet structure, and the lower end surface of the reinforcing ribs 150 is flush with the outer bottom wall of the groove body.

[0044] It should be noted that, continuing as Figure 2 shown, in this embodiment, since the entire tray body is a sheet structure and in order to avoid excessive increase in the weight of the tray body 100 due to adding the reinforcing ribs 150, the reinforcing ribs 150 are also formed by a groove body that is recessed downward from the sheet structure at the lower end surface of the protruding sheet structure.

[0045] In this embodiment, the plastic suction tray structure includes two reinforcing ribs 150, and the two reinforcing ribs 150 are located at both ends in the length direction of the battery cover and extend along the width direction of the battery cover.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
