Description

Technical Field

[0001] The present application relates to the technical field of lithium-ion battery manufacturing, and particularly relates to a square battery tray. Background Art

[0002] The square battery tray is an important basic component in the formation and grading equipment of square lithium-ion power batteries. Its quality determines the bearing efficiency and life of the battery. However, there are still certain defects in the existing battery trays.

[0003] In the related art, the patent with the publication number CN214825004U discloses a combined tray, which includes a tray body and several combined partition bodies. The tray body is a tray-shaped structure with an open upper end, a closed bottom surface and a peripheral surface. The combined partition bodies are divided into longitudinal partition bodies and transverse partition bodies. The longitudinal partition bodies are used to separate the longitudinal space of the tray body, and the transverse partition bodies are used to separate the transverse space of the tray body. Several through holes for the longitudinal partition bodies to pass through are opened on the transverse partition bodies, and the through holes are evenly arranged on the transverse partition bodies. By setting detachable combined partition bodies in the tray body, the storage and transportation space in the tray can be flexibly configured, increasing the versatility.

[0004] However, its tray structure is simple and lacks a protection structure. When the battery is placed into the tray by using an automated device and the battery falls into the tray groove, the bottom of the battery is likely to collide with the bottom wall of the groove, which is not conducive to protecting the battery. Moreover, when the battery slides down along the four surrounding side walls, the air in the groove is squeezed and cannot be quickly discharged, generating resistance to the battery, which will cause the battery to be loaded smoothly and is not conducive to the battery being quickly loaded into the tray. Therefore, it is necessary to study and improve the above structure, and provide a square battery tray in order to achieve a more practical purpose. Summary of the Invention

[0005] Aiming at the deficiencies or one of the deficiencies in the above background art, the embodiments of the present application provide a square battery tray, which is convenient for quickly loading the battery and can ensure that the battery does not collide with the bottom wall of the groove, achieving the purpose of improving the practicality of the battery tray.

[0006] The embodiments of the present application provide a square battery tray, including:

[0007] An outer frame, on the bottom of which there are evenly arranged ventilation holes;

[0008] A lining, which is arranged inside the outer frame. There are evenly arranged battery placement grooves on the lining, and through holes communicating with the ventilation holes are arranged on the bottom walls of the battery placement grooves;

[0009] A buffer pad, which is arranged on the bottom wall of the battery placement groove, and the buffer pad is used to support the square battery.

[0010] In some embodiments, a first heat dissipation opening with an upward opening is provided through the large surface of the side wall of the battery placement groove, and a second heat dissipation opening with an upward opening is provided through the small surface of the side wall of the battery placement groove.

[0011] In some embodiments, a first heat dissipation groove connecting the first heat dissipation opening and the bottom wall is provided on the large surface of the side wall of the battery placement groove, and a second heat dissipation groove communicating with the first heat dissipation opening is provided between the large surfaces of the side walls of adjacent battery placement grooves.

[0012] In some embodiments, a first strip-shaped groove connecting the notch and the bottom wall is provided on the large surface of the side wall of the battery placement groove, and a second strip-shaped groove connecting the notch and the bottom wall is provided on the small surface of the side wall of the battery placement groove.

[0013] In some embodiments, guiding inclined surfaces for the battery to slide into the battery placement groove are provided around the notch of the battery placement groove.

[0014] In some embodiments, the inner lining is integrally formed of a soft material, and the soft material is any one of polypropylene foam, polyethylene soft foam, and polyurethane soft foam.

[0015] In some embodiments, a clamping groove is provided on the bottom of the outer frame, and a clamping block adapted to the clamping groove is provided on the bottom surface of the inner lining.

[0016] In some embodiments, a holding hole is provided through the frame wall of the outer frame, and a wavy protrusion is provided on the top wall of the holding hole.

[0017] In some embodiments, a first notch with bottom and lateral openings is provided on a short side of one side of the bottom of the outer frame, and a second notch with bottom and lateral openings is provided on a long side of one side of the bottom of the outer frame.

[0018] In some embodiments, a nut is embedded on the bottom surface of the inner lining, a bolt connecting the nut is installed on the bottom of the outer frame, and positioning holes are provided at the four corners of the bottom of the outer frame.

[0019] The beneficial effects brought by the technical solutions provided in this application include:

[0020] The embodiments of this application provide a square battery tray. Since ventilation holes are evenly arranged on the bottom of the outer frame; the inner lining is arranged inside the outer frame, and battery placement grooves are evenly arranged on the inner lining, and through holes communicating with the ventilation holes are provided on the bottom wall of the battery placement grooves; a buffer pad is arranged on the bottom wall of the battery placement grooves.

[0021] Therefore, when the square battery slides along the four side walls of the battery placement groove, the air in the groove can be quickly discharged from the communicating through holes and ventilation holes after being squeezed, so that the battery can quickly fall into place under the action of gravity. At the same time, a buffer pad is provided on the bottom wall of the battery placement groove, and the buffer pad can support the bottom end of the battery.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0033] In view of the deficiencies or one of the deficiencies in the above background art, the embodiments of the present application provide a square battery tray, which facilitates the rapid loading of batteries and can ensure that the batteries do not collide with the bottom wall of the groove, achieving the purpose of improving the practicality of the battery tray.

[0034] See Figures 1 to 7 As shown, the embodiments of the present application provide a square battery tray, including:

[0035] An outer frame 1, on the bottom of which there are evenly arranged ventilation holes 2;

[0036] A lining 3, which is arranged inside the outer frame 1. On the lining 3, there are evenly arranged battery placement grooves 4, and on the bottom wall of the battery placement grooves 4, there are through holes 5 communicating with the ventilation holes 2;

[0037] A buffer pad 6, which is arranged on the bottom wall of the battery placement groove 4 and is used to support the square battery.

[0038] The square battery tray of the embodiments of the present application includes an outer frame 1 and a lining 3. The lining 3 is installed inside the outer frame 1, which is convenient for flowing on the production line with the outer frame 1. The lining 3 fits with the bottom and side walls of the outer frame 1, and on the lining 3, there are evenly arranged battery placement grooves 4 for accommodating square batteries.

[0039] The outer frame 1 is provided with evenly arranged ventilation holes 2, and the bottom walls of the battery placement grooves 4 on the lining 3 are all provided with through holes 5 communicating with the ventilation holes 2. When the square battery slides down along the surrounding side walls of the battery placement groove 4, the air in the groove can be quickly discharged from the through holes 5 and the ventilation holes 2 after being squeezed, so that the battery can quickly fall into place under the action of gravity.

[0040] At the same time, a buffer pad 6 is adhered to the bottom wall of the battery placement groove 4, and the buffer pad 6 is located at both ends of the bottom wall. When the automated equipment places the battery, when the battery falls into the battery placement groove 4, the buffer pad 6 can play a buffering role to ensure that the bottom of the battery is not bruised or knocked. In addition, it can also play a buffering role during the probe pressing and battery testing process to avoid inaccurate test data caused by the deformation of the battery due to being pressed.

[0041] It should be noted that dust and other particulate foreign matters are likely to accumulate on the bottom wall of the battery placement groove 4. The buffer pad 6 can lift the battery to avoid contact between the battery and the bottom wall of the battery placement groove 4, thereby reducing the contact amount of foreign matters such as dust and static electricity dust adhering to the bottom wall of the battery. Exemplarily, the buffer pad 6 can be made of foamed rubber strip.

[0042] In addition, it should be noted that the bottom of the outer frame 1 is supported on the idler or strip of the production line, and the vent holes 2 on the bottom of the outer frame 1 will not be closed by the support surface, so it can play a role in exhausting air. At the same time, during the process of the probe pressing and testing the battery, the battery will release heat during charging and discharging. The through holes 5 and the vent holes 2 cooperate to also play a role in ventilation and heat dissipation.

[0043] In some alternative embodiments: Refer to Figures 1 to 7 As shown, the embodiment of the present application provides a square battery tray. The side wall large surface of the battery placement groove 4 of the square battery tray is provided with a first heat dissipation port 7 with an upward opening, and the side wall small surface of the battery placement groove 4 is provided with a second heat dissipation port 8 with an upward opening.

[0044] The side wall of the battery placement groove 4 in the embodiment of the present application has a large surface and a small surface, which respectively correspond to the large and small sides of the square battery, so as to stably restrain the placed square battery. In addition, the first heat dissipation port 7 is opened on the large surface, and in cooperation with the second heat dissipation port 8 opened on the small surface, it can ventilate and dissipate heat on the four sides of the square battery, improving the heat dissipation effect on the battery.

[0045] In some alternative embodiments: Refer to Figures 1 to 7 As shown, the embodiment of the present application provides a square battery tray. The side wall large surface of the battery placement groove 4 of the square battery tray is provided with a first heat dissipation groove 9 connecting the first heat dissipation port 7 and the bottom wall, and a second heat dissipation groove 10 communicating with the first heat dissipation port 7 is provided between the side wall large surfaces of adjacent battery placement grooves 4.

[0046] The first heat dissipation grooves 9 are opened on both large surfaces on both sides in the battery placement groove 4 of the embodiment of the present application. The bottom end of the first heat dissipation groove 9 is flush with the bottom wall of the battery placement groove 4, and the top end of the first heat dissipation groove 9 communicates with the first heat dissipation port 7, which can improve the heat dissipation effect on the battery.

[0047] In addition, a second heat dissipation groove 10 communicating with the first heat dissipation port 7 is also opened between the large surfaces of adjacent battery placement grooves 4. The second heat dissipation groove 10 and the first heat dissipation port 7 cooperate to further improve the heat dissipation effect on the battery. At the same time, the first heat dissipation groove 9 and the second heat dissipation groove 10 can reduce the weight of the inner lining 3, thereby reducing the production consumables of the inner lining 3 and lowering the production cost.

[0048] In some alternative embodiments: Refer to Figures 1 to 7As shown in the figure, an embodiment of the present application provides a square battery tray.

[0049] The first strip-shaped groove 11 and the second strip-shaped groove 12 in the embodiment of the present application can serve as exhaust grooves. When the battery slides down along the side walls around the battery placement groove 4, the air in the battery placement groove 4 can be squeezed out upward from the exhaust grooves, thereby reducing the air resistance during loading and ensuring that the battery is quickly loaded in place.

[0050] In some other embodiments, the first strip-shaped groove 11 and the second strip-shaped groove 12 can serve as reserved grooves for pasting cushion strips. When the large and small surfaces of the battery placement groove 4 do not match the square battery, that is, when the size of the square battery is smaller than the battery placement groove 4, cushion strips can be pasted in the first strip-shaped groove 11 and the second strip-shaped groove 12. The cushion strips are convexly arranged and can fit and limit the side wall of the square battery. Exemplarily, the cushion strips can be made of foamed rubber strips and are not easy to fall off when pasted.

[0051] In some alternative embodiments: Refer to Figures 1 to 7 As shown in the figure, an embodiment of the present application provides a square battery tray. Guide inclined surfaces 13 for the battery to slide into the battery placement groove 4 are provided around the notch of the battery placement groove 4 of the square battery tray.

[0052] The guide inclined surfaces 13 are provided around the notch of the battery placement groove 4 in the embodiment of the present application. The battery can slide into the battery placement groove 4 along the guide inclined surfaces 13, which can reduce the position accuracy requirements for the battery to be placed in place. Exemplarily, with the vertical plane perpendicular to the bottom wall of the battery placement groove 4 as the reference, the angle between the guide inclined surface 13 and the vertical plane is 15°, which can meet the working range for the automatic working equipment to place the battery and effectively ensure the compatibility of the battery product placement.

[0053] In some alternative embodiments: Refer to Figures 1 to 7 As shown in the figure, an embodiment of the present application provides a square battery tray. The inner lining 3 of the square battery tray is integrally formed of a soft material, and the soft material is any one of polypropylene foam plastic, polyethylene soft foam plastic, and polyurethane soft foam plastic.

[0054] The inner lining 3 in the embodiment of the present application is integrally formed of a soft material, which can ensure that the part where the battery blue film contacts the inner lining 3 is a soft material, prevent the blue film wrapped on the battery from being worn and scratched, and reduce the amount of battery appearance defects caused by automatic placement during the battery production process.

A holding hole 16 is penetrated through the frame wall of the outer frame 1 of the square battery tray, and a wavy protrusion is provided on the top wall of the holding hole 16.

[0058] A holding hole 16 is penetrated through the frame wall of the outer frame 1 of the embodiment of the present application, and a wavy protrusion is provided on the top wall of the holding hole 16, which can play a role in preventing incorrect holding, ensure the holding feel of employees during the manual feeding process, and enable the outer frame 1 to immediately feel that the outer frame 1 is placed in the wrong direction after being inverted.

[0059] In some alternative embodiments: Refer to Figures 1 to 7 As shown in the figure, an embodiment of the present application provides a square battery tray. A first notch 17 with a bottom and a lateral opening is provided on one short side of the bottom of the outer frame 1 of the square battery tray, and a second notch 18 with a bottom and a lateral opening is provided on one long side of the bottom of the outer frame 1.

[0060] The first notch 17 and the second notch 18 of the embodiment of the present application can cooperate with the workstations of the production line to achieve an anti-fooling function, reduce the frequency of misplacing the tray direction, effectively intercept the trays put in the wrong direction, and reduce the occurrence of faults during the production process. Exemplarily, a micro switch is provided at the top of the telescopic rod on the production line workstation. When the outer frame 1 moves into place, the telescopic rod drives the micro switch to rise. If the outer frame 1 is not inverted front to back or left to right, the micro switch will probe into the first notch 17 and the second notch 18 and will not be triggered. On the contrary, the micro switch will be triggered by the bottom of the frame, indicating that the outer frame 1 is placed in the wrong direction or has not moved into place.
