[0002] In the field of battery top cover production, plastic suction trays are widely used in the packaging of battery top covers to ensure their safety and integrity during production, storage, and transportation. This packaging method can not only effectively protect the battery top cover from damage and prevent it from being affected by external forces or the external environment during production or transportation. When ordinary battery top covers are packaged, the large surface of the top cover panel is placed in the inner grid of the plastic suction tray. However, for the current square battery top cover with pins, its top cover panel is relatively slender, and due to the pins, its overall height in the height direction reaches 50 - 60 millimeters. If packaged according to the original method, the height of the plastic suction tray needs to be more than 60 millimeters, which will affect the space utilization rate of the packaging, reduce the transportation efficiency, and cannot guarantee the safety of product transportation. Moreover, the inner grid of the plastic suction tray is narrow and long, which is not conducive to plastic suction processing. Therefore, it is necessary to design a plastic suction tray for the top cover of a new energy battery with a large space utilization rate, which can ensure transportation efficiency, protect the product from damage, and is conducive to plastic suction processing.

DETAILED DESCRIPTION

[0027] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figures 1-5 , an embodiment provided by the utility model:

[0029] A plastic suction tray for the top cover of a new energy battery, comprising a plastic suction tray body 2. The plastic suction tray body 2 is of a box structure. A box wall 3 is fixedly arranged on the peripheral side of the plastic suction tray body 2. Five positioning bosses 5 are fixedly arranged on the inner bottom surface 4 of the plastic suction tray body 2 along the length direction. The top surface of the positioning boss 5 is flush with the upper surface of the box wall 3. Eight inner grid partitions 6 are symmetrically and fixedly arranged on the two long side box walls 3, four on each side. The positioning bosses 5 and the inner grid partitions 6 divide the inner part of the box of the plastic suction tray body 2 into five inner grids 7. The middle parts of adjacent inner grids 7 are connected through, which is beneficial to the plastic suction forming of the plastic suction tray. The inner grid 7 is provided with a positioning structure for positioning the battery top cover 1. On the reverse side of the box wall 3, a thin wall 8 and a box wall groove 9 are formed at the outer bottom of the plastic suction tray body 2. On the reverse side of the inner bottom surface 4 and the positioning boss 5, a bottom surface convex block 10 and a boss groove 11 are respectively formed at the outer bottom of the plastic suction tray body 2. Fourteen first support buckles 12 are fixedly arranged on the outer wall of the bottom surface convex block 10, five on each long side and two on each short side. A number of second support buckles 13 are fixedly arranged on the inner wall of the boss groove 11. The top surfaces of the first support buckles 12 and the second support buckles 13 are flush and slightly lower than the bottom surface convex block 10. When the plastic suction trays are stacked, the first support buckles 12 and the second support buckles 13 in the upper plastic suction tray support on the positioning bosses 5 in the lower plastic suction tray, playing a supporting role to prevent the upper plastic suction tray from sinking further, and can well protect the products (i.e., the battery top cover 1, the same below) in the lower plastic suction tray from being squeezed. Due to the existence of the draft angle, the box wall 3 and the positioning boss 5 are in the shape of a frustum of a cone. The inner space at the bottom of the box wall groove 9 is larger than the upper surface of the box wall 3, and the inner space at the bottom of the boss groove 11 is larger than the upper surface of the positioning boss 5. Since the top surfaces of the first support buckles 12 and the second support buckles 13 are slightly lower than the bottom surface convex block 10, as Figure 11 shown, when the first support buckles 12 and the second support buckles 13 in the upper plastic suction tray are placed on the positioning bosses 5 of the lower plastic suction tray, the box wall 3 and the positioning boss 5 in the lower plastic suction tray respectively extend into the box wall groove 9 and the boss groove 11 in the upper plastic suction tray, forming a step limit to prevent the sliding and adhesion of the upper plastic suction tray, and the production process is more smooth.

[0030] Among them, the positioning structure includes a pin support 14, a top cover end positioning surface 16, a top cover panel positioning surface 17 and a top cover bottom positioning surface 18. The pin support 14 is symmetrically fixed at both ends of the positioning boss 5. The pin support 14 is located on the inner bottom surface 3 and the two ends are respectively fixedly connected to the positioning boss 5 and the long side box wall 3. The height of the pin support 14 is equal to (top cover panel 101 width-pin 103 width) / 2. The pin support 14 is used to support the pins 103 at both ends of the battery top cover 1, so that the top cover panel 101 of the battery top cover 1 is kept vertical to the inner bottom surface 4, so that the battery top cover 1 can be placed more stably. The pin support 13 is fixedly provided with a pin partition 15 at one end close to the long side box wall 3, which is used to separate products to avoid mutual contact between products and protect the pins. The foot 103 is not scratched, the top cover end positioning surface 16 and the top cover panel positioning surface 17 are arranged at the four corners of the inner grid 7 and are perpendicular to each other, the top cover bottom positioning surface 18 is the two side surfaces of the positioning boss 5, the top cover end positioning surface 16 limits the two ends of the top cover panel 101, which is used to limit the longitudinal displacement of the top cover panel 101, the top cover panel positioning surface 17 and the top cover bottom positioning surface 18 respectively limit the top cover panel 101 and the top cover bottom 102, which is used to limit the lateral displacement of the top cover panel 101, and by slotting the blister tray body 2 to make other parts of the battery top cover 1 avoid the blister tray body 2, interference is prevented, the contact area between the blister tray body 2 and the product is reduced, the risk of product scratches is reduced, and it is also beneficial to the blister forming of the blister tray.

[0031] Among them, the box wall draft angle α is 2-5 degrees, the positioning boss draft angle β is 2-5 degrees, and in this embodiment, α=β=3 degrees, which is conducive to vacuum forming processing.

[0032] Among them, a plurality of hand-gripping grooves 19 are fixedly provided on the inner side of the box wall 3 and the positioning boss 5 to facilitate taking out the product.

[0033] A plurality of reinforcing grooves 20 are fixedly disposed on the outer side of the box wall 3 to increase the strength of the blister tray body 2 .

[0034] Among them, electrode marks 21 are set at the four corners of the blister tray body 2. The identification symbols of the electrode marks 21 are "+" and "-", which are used to keep the product direction consistent when the product is placed.

[0035] A notch 22 is provided at one corner of the blister tray body 2 for maintaining the consistency of directions of the blister trays when the blister trays are stacked.

[0036] The blister tray body 2 and its structure are integrally formed by the blister process.

[0037] like Figures 6-9As shown, when the battery top cover 1 is packaged, ten battery top covers 1 can be placed in each blister tray, and two battery top covers 1 can be placed in each inner compartment 7. The battery top cover 1 is placed on its side so that the side of the top cover panel 101 is placed on the inner bottom surface 4 and the pin 103 is placed on the pin support 14, keeping the top cover panel 101 in a vertical state. For the two battery top covers 1 in each inner compartment 7, their pins 103 cross each other, increasing the utilization rate of the packaging space of the blister tray, reducing the packaging and transportation costs, improving the transportation efficiency, and reducing the production cost. The pins 103 are separated by a partition 15, and the longitudinal and lateral limits of the top cover panel 101 are provided by the top cover end positioning surface 16, the top cover panel positioning surface 17, and the top cover bottom positioning surface 18 to prevent damage to the product caused by external forces or the external environment during production or transportation. After the products are placed in multiple blister trays, the blister trays can be stacked to save transportation space.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
