Description

Technical Field

[0001] The utility model relates to the technical field of ear charging of a hot pressing forming machine, in particular to an adjusting mechanism for ear charging of a hot pressing forming machine. Background Art

[0002] In the technical field of ear charging of a hot pressing forming machine, with the wide application of energy storage devices such as lithium batteries, higher requirements are put forward for the charging efficiency and charging quality in the battery production process. Especially in the hot pressing forming stage, the charging process of the ear has a crucial impact on the battery performance. Among them, there is a specific charging plate structure for charging a battery as follows:

[0003] Chinese patent document with publication number CN220963454U discloses a shiftable charging plate structure of a lithium battery hot pressing forming machine, which specifically discloses: including a forming machine aluminum layer plate and a shiftable ear charging assembly movably arranged left and right on the forming machine aluminum layer plate. The shiftable ear charging assembly consists of an ear pressing plate and a charging plate fixed on the ear pressing plate. The ear pressing plate includes a pressing plate groove, a guiding column, a spring and an insulating pressing block. The pressing plate groove is movably located left and right at the bottom of the forming machine aluminum layer plate, and the insulating pressing block is movably located up and down at the bottom of the pressing plate groove. A plurality of springs are elastically arranged between the insulating pressing block and the pressing plate groove. The front and rear ends of the pressing plate groove are bent upwards to form a first fixing ear and a second fixing ear respectively. The charging plate is movably located left and right at the top of the forming machine aluminum layer plate, and a row of fixed tooth holes is arranged at the rear side of the forming machine aluminum layer plate.

[0004] As can be seen from the above, when the existing shiftable charging plate structure needs to adjust the distance between the charging plates, it is necessary to first loosen the screws on the second fixing ears of the left and right shiftable ear charging assemblies, so that the ear pressing plate and the charging plate can move freely left and right on the surface of the forming machine aluminum layer plate to adapt to double-sided ear-out battery cells of different heights. However, when the existing shiftable charging plate structure adjusts the distance between the charging plates, the operation is not convenient. It is necessary to adjust the ear pressing plate and the charging plate on the left and right sides respectively, which is time-consuming and laborious and cannot be adjusted simultaneously. Therefore, an adjusting mechanism for ear charging of a hot pressing forming machine is provided to solve the above technical problems. Summary of the Utility Model

[0026] The following describes in detail an adjustment mechanism for ear charging of a hot pressing and forming machine of the present utility model with reference to the accompanying drawings.

[0027] As Figure 1 shown, an embodiment of an adjustment mechanism for ear charging of a hot pressing and forming machine of the present utility model includes a support plate 1. A plurality of support plates 1 are arranged side by side and equidistantly on the hot pressing and forming machine, and each support plate 1 can slide on the hot pressing and forming machine; among them, a pair of charging modules for charging the battery cells are provided on the support plate 1. When the support plate 1 slides on the hot pressing and forming machine, it will drive the charging modules to move together; when charging the battery cells is required, two adjacent support plates 1 are taken as a group, and multiple groups of support plates 1 are provided on the hot pressing and forming machine. After placing the ears of the battery cells in the gap between the two support plates 1, the two support plates 1 can be controlled to slide towards the same side, and while sliding, the distance between the support plates 1 will gradually become smaller, so as to clamp the ears of the battery cells between different charging modules, making the ears contact the charging modules, thereby charging the battery cells; in addition, by providing a pair of charging modules on the support plate 1, a pair of battery cells can be placed between the two support plates 1, so that a group of support plates 1 can charge a pair of battery cells.

[0028] Specifically, the charging module includes a first moving mechanism 2 and a second moving mechanism 201 movably arranged on the support plate 1. The first moving mechanism 2 and the second moving mechanism 201 can move towards or away from each other, and the moving direction is the same as the length direction of the support plate 1; among them, a first charging plate 3 for electrically connecting with the positive electrode of the power supply is installed on the first moving mechanism 2, and a second charging plate 31 for electrically connecting with the negative electrode of the power supply is installed on the second moving mechanism 201. When the first moving mechanism 2 and the second moving mechanism 201 move towards or away from each other, they will drive the first charging plate 3 and the second charging plate 31 to move towards or away from each other as well, so as to adjust the distance between the first charging plate 3 and the second charging plate 31, thereby enabling charging of battery cells of different sizes and improving the practicability.

[0029] Furthermore, pressing mechanisms 4 for pressing the tabs are provided on both the first movable mechanism 2 and the second movable mechanism 201. The pressing mechanism 4 is placed on the side of the support plate 1 away from the first charging plate 3 (or the second charging plate 31). After placing the tabs of the battery cell between the two support plates 1, the two support plates 1 can be controlled to slide towards the same side, and the distance between the two support plates 1 will gradually decrease, so as to apply pressure to the tabs of the battery cell through the pressing mechanism 4 to press them into contact with the first charging plate 3 and the second charging plate 31, thereby charging the battery cell. Additionally, heating plates 6 for keeping the battery cell at a constant temperature during charging are installed on both sides of the support plate 1. During the charging process of the battery cell, the heating plate 6 is operated to heat the environment around the battery cell to about 40 °C, so that the battery maintains the best charging state.

[0030] To facilitate the adjustment of the distance between the first movable mechanism 2 and the second movable mechanism 201, a fixed shaft 7 arranged axially and vertically is provided at the bottom of the support plate 1. The fixed shaft 7 is located at the middle position between one movable mechanism 2 and the second movable mechanism 201, and a gear 8 is rotatably provided on the fixed shaft 7. A first rack 9 is installed on the first movable mechanism 2, a second rack 10 is installed on the second movable mechanism 201, and the first rack 9 and the second rack 10 are respectively located on both sides of the gear 8. When the first movable mechanism 2 is pushed to move on the support plate 1, the first movable mechanism 2 drives the first rack 9 to move together. Under the driving action of the gear 8, the second rack 10 will be driven to move together, and the moving directions of the first rack 9 and the second rack 10 are opposite, so that the first movable mechanism 2 and the second movable mechanism 201 can move towards each other or away from each other. Under the action of the first rack 9, the second rack 10 and the gear 8, only by applying force to the first movable mechanism 2 can the distance between the first movable mechanism 2 and the second movable mechanism 201 be adjusted, improving the convenience of adjustment.

[0031] Such as Figures 2-3As shown, the first movable mechanism 2 includes an upper movable block 21 placed above the support plate 1 and a lower movable block 22 placed below the support plate 1. Among them, a sliding groove 24 with a length direction consistent with that of the support plate 1 is provided at the bottom of the support plate 1, and the lower movable block 22 is slidably arranged on the support plate 1 through the sliding groove 24; when a force is applied to the lower movable block 22, the lower movable block 22 slides on the support plate 1, thereby driving the pressing mechanism 4 and the first charging plate 3 to move together to adjust the distance between the first charging plate 3 and the second charging plate 31. In addition, the lower movable block 22 and the upper movable block 21 are connected by a connecting plate 23. When the lower movable block 22 slides on the support plate 1, under the action of the connecting plate 23, the upper movable block 21 is driven to move together; a limiting mechanism 5 for limiting the upper movable block 21 is installed on the upper movable block 21. After the distance between the first charging plate 3 and the second charging plate 31 is adjusted, under the action of the limiting mechanism 5, the upper movable block 21 is limited, and at the same time, the lower movable block 22 can also be limited, so that the lower movable block 22 will not deviate from its original position after being accidentally touched. The structure of the first movable mechanism 2 is the same as that of the second movable mechanism 201, and the moving directions are opposite.

[0032] As Figures 3-4 shown, the pressing mechanism 4 includes a pressing plate 41 arranged vertically and used for pressing the tab. Support legs 42 are formed at both the upper and lower ends of the pressing plate 41, and the support legs 42 at the upper and lower ends are respectively slidably arranged on the upper movable block 21 and the lower movable block 22. A first spring 47 for applying a force to the pressing plate 41 is provided between the pressing plate 41 and the connecting plate 23; after placing the tab of the battery cell between the two support plates 1, the two support plates 1 can be controlled to slide towards the same side, and the distance between the two support plates 1 will gradually become smaller. When the pressing plate 41 contacts the tab, the support plate 1 continues to slide, and the first spring 47 is compressed to apply a force to the pressing plate 41, and the tab of the battery cell is pressed by the pressing plate 41 to press it into contact with the first charging plate 3 and the second charging plate 31, thereby charging the battery.

[0033] Furthermore, the upper movable block 21 and the lower movable block 22 are provided with mounting grooves 44 for inserting the legs 42, and a mounting plate 45 is fixed in each mounting groove 44, and a fixing rod 46 is arranged horizontally in the length direction on the mounting plate 45, and the length direction of the fixing rod 46 is perpendicular to the length direction of the pressing plate 41; in addition, each leg 42 is provided with a guide hole 43 whose length direction is consistent with the force direction of the pressing plate 41, and different fixing rods 46 are respectively placed in different guide holes 43. The support plate 1 moves so that after the pressing plate 41 applies pressure to the pole ear, the pressing plate 41 slides on the upper movable block 21 and the lower movable block 22, the fixing rod 46 slides in the guide hole 43, and the first spring 47 is compressed to apply force to the pressing plate 41, so that the pole ear is pressed by the pressing plate 41, so that the pole ear can fully contact the first charging plate 3 and the second charging plate 31.

[0034] like Figures 5-6 As shown, the limiting mechanism 5 includes a fixed block 51 arranged on the upper movable block 21, wherein a pair of chambers 52 are formed in the fixed block 51, and a slider 53 is slidably provided in each chamber 52, and a second spring 54 is also provided in the chamber 52, and the second spring 54 is placed above the slider 53 to apply a downward force to the slider 53; a connecting frame 55 placed below the fixed block 51 is fixedly connected to the slider 53, and under the action of the slider 53, the connecting frame 55 slides up and down on the fixed block 51. A vertically arranged clamping rod 56 is provided on the connecting frame 55, and a clearance groove 57 for accommodating the clamping rod 56 is provided on the side of the upper movable block 21 close to the support plate 1, and a plurality of limiting grooves 58 (such as equidistantly arranged in a row) for limiting the clamping rod 56 are provided on the side of the support plate 1 close to the upper movable block 21. Figure 3 As shown). The bottom end of the clamping rod 56 is inserted into the limiting groove 58. When force is applied to the lower movable block 22 to make it slide on the support plate 1, the upper movable block 21 moves together, so that the clamping rod 56 is disengaged from the limiting groove 58, and the second spring 54 is compressed. When the upper movable block 21 is driven to move to the specified position (the spacing between the first charging plate 3 and the second charging plate 31 is to the specified distance) and the clamping rod 56 is aligned with the corresponding limiting groove 58, under the action of the compressed second spring 54, the clamping rod 56 is automatically inserted into the limiting groove 58 to limit the upper movable block 21; when the spacing between the first charging plate 3 and the second charging plate 31 is adjusted, when an accidental collision occurs, the spacing between the first charging plate 3 and the second charging plate 31 will not change, thereby improving the stability after adjustment.

[0035] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0036] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
