Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery core transport tray. Background Art

[0002] As a commonly used power source, lithium-ion batteries can provide stable power for a long time, are easy to carry, and have stable and reliable performance. They have broad application prospects in portable electronic devices, electric vehicles, and many other fields. The battery cell is the smallest unit of the battery pack and also the energy storage unit. After fixing multiple battery cells, they are electrically connected with a bus to form a battery module. When several modules are controlled or managed by the battery management system and the thermal management system, they form a battery pack. In the battery production process, different production processes are a certain distance apart or are produced at different times. It is often used to load the battery cells into pallets for transportation.

[0003] The existing battery cell transfer pallet is prepared by injection molding process. Each pallet is provided with at least 100 placement cavities for placing and limiting the battery cells. The weight of each battery cell is 400~500g. Considering the cost and weight reasons, the thickness of the existing battery cell transfer pallet is about 3mm. Since the bottom plate of the existing battery cell transfer pallet is designed according to the plane, the bearing capacity of the pallet is small. When the battery cell is placed on the bottom plate plane, the bottom plate plane will produce a concave deformation. In the actual pallet bearing process, when the battery cell is fully loaded, the concave deformation of the pallet is ≥2mm, which leads to a large deformation of the pallet and a deformation of the bottom plate ≤2mm, which will cause the pallet to be unable to fix the battery cell and reduce the service life of the pallet. In order to improve the bearing capacity of the bottom plate of the battery cell transfer pallet, the solution of increasing the thickness of the bottom plate can be adopted, but this greatly increases the weight of the battery cell transfer pallet and the manufacturing cost of the pallet, and is not suitable for use in production. Therefore, a new battery cell transfer pallet is urgently needed to solve the above problems. Summary of the invention

[0004] The utility model aims to solve the problem of small carrying capacity of existing battery cell transport trays and to provide a battery cell transport tray.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0006] A battery cell transfer tray comprises a bottom plate and side walls, wherein the side walls are enclosed on the outer peripheral edge of the bottom plate to form a accommodating chamber, a support frame is installed in the accommodating chamber, and a plurality of battery cell placement cavities are arranged on the support frame, the shape of the battery cell placement cavities matches the battery cells, and protrusions are arranged on the bottom plate at positions corresponding to the battery cell placement cavities, so that one end of the battery cell can pass through the battery cell placement cavity and contact the protrusion on the bottom plate.

[0007] In the technical solution of the utility model, the battery cell transfer tray includes a bottom plate and side walls, the side walls are enclosed on the outer peripheral edge of the bottom plate to form a accommodating chamber, the accommodating chamber is a hollow structure with an opening on one side, a support frame is arranged in the accommodating chamber, a battery cell placement cavity matching the battery cell is arranged on the support frame, a protrusion is arranged at a position on the bottom plate corresponding to the battery cell placement cavity, the protrusion is arranged at the lower end of the battery cell placement cavity so that one end of the battery cell can pass through the battery cell placement cavity and contact the protrusion on the bottom plate, the setting of the protrusion can increase the thickness of the bottom plate at the corresponding position of the battery cell placement cavity, when the battery cell is placed in the battery cell placement cavity, the gravity of the battery cell acts on the protrusion of the bottom plate, the setting of the protrusion can increase the bearing capacity of the bottom plate corresponding to the battery cell placement cavity, and reduce the deformation of the bottom plate of the battery cell transfer tray.

[0008] As a preferred solution of the utility model, the support frame includes a first support plate and a second support plate, the second support plate is located between the first support plate and the bottom plate, the first support plate is provided with a plurality of first through holes, the second support plate is provided with a plurality of second through holes corresponding to the first through holes, the number of the first through holes and the second through holes is the same, the first through holes and the second through holes constitute the battery cell placement cavity, one end of the battery cell passes through the first through hole and the second through hole in sequence to contact the protrusion on the bottom plate.

[0009] As a preferred solution of the utility model, the first support plate includes a first frame body, the first frame body is provided with the first through holes, and the first through holes are arranged in an array along a first direction and a second direction. It should be noted that the first direction is the length direction of the first frame body, and the second direction is the width direction of the first frame body.

[0010] As a preferred solution of the present invention, the second support plate includes a second frame and a support column, the second frame is provided with the second through hole, and the support column is arranged on the surface of the second frame away from the base plate, and is used to separate the first support plate and the second support plate to reduce the weight of the support frame, thereby reducing the load on the base plate and reducing the deformation of the base plate.

[0011] As a preferred solution of the utility model, adjacent battery cell placement cavities are arranged at equal intervals, and the interval distance between adjacent battery cell placement cavities is set to 10-20mm. The interval distance setting enables the tray to place as many batteries as possible while ensuring the strength of the structure. For example, if the distance is set to less than 10mm, the distance between the battery cell placement cavities is too close, and the load per unit area of ​​the bottom surface of the tray is too large, which can easily cause the tray to deform. If the interval distance is too large, for example, it is set to a distance greater than 25mm, it is not conducive to placing more batteries in a limited space, which will increase the number of trays used and increase production costs. Therefore, it is more appropriate to set the interval distance to between 10 and 20mm.

[0012] As a preferred embodiment of the utility model, a notch is provided on the top of the battery cell placement cavity for convenient removal and placement of the battery cell. The cross-section of the notch is V-shaped.

[0013] As a preferred embodiment of the present invention, when the battery cell is a cylindrical battery cell, the inner diameter of the battery cell placement cavity is 3 to 8 mm larger than the outer diameter of the battery cell.

When the battery cell is placed in the battery cell placement cavity, there is a gap between the battery cell and the inner wall of the battery cell placement cavity. The battery cell is taken out of or placed in the battery cell placement cavity of the tray. At the same time, the gap between the battery cell and the inner wall of the battery cell placement cavity is relatively small, which will not cause shaking of the placed battery cell, thereby ensuring the stability of the battery cell.

[0014] As a preferred solution of the present utility model, the cross-section of the protrusion is rectangular, and the height of the protrusion is 1.5~4mm.

[0015] As a preferred solution of the utility model, a through avoidance hole is provided on the bottom plate at a position corresponding to the battery cell placement cavity, the inner diameter of the avoidance hole is smaller than the inner diameter of the battery cell placement cavity, and the avoidance hole is provided within the range of the protrusion. Generally speaking, a pressure relief structure is provided at the bottom of the battery cell, and the avoidance hole provided on the bottom plate of the tray can avoid the pressure relief structure. When the pressure inside the battery cell is too high, the pressure relief structure can be flushed open and flow out through the avoidance hole to avoid explosion, further ensuring the safety of the battery cell and personnel.

[0016] As a preferred solution of the utility model, a transport hand groove is provided on the outer surface of the side wall. By providing the transport hand groove, it is convenient for a robot or an operator to clamp the pallet, thereby facilitating the transportation of the pallet.

[0018] As a more preferred embodiment of the present invention, the top surface of the side wall is provided with a step surface, and the lower bottom surface of the cover is provided with an inlay panel, and the side surface of the inlay panel is tightly matched with the side surface of the step surface. By utilizing the fit between the inlay panel and the step surface, the cover can be buckled on the side wall and is not easy to fall off, thereby preventing dust and foreign matter from entering and contaminating the battery cell.

[0036] Example 1

[0037] A battery cell transfer tray comprises a bottom plate 1 and side walls 2, wherein the side walls 2 are enclosed on the outer peripheral edge of the bottom plate 1 to form a accommodating chamber, a support frame 3 is installed in the accommodating chamber, a plurality of battery cell placement cavities 4 are arranged on the support frame 3, and the shape of the battery cell placement cavities 4 matches the battery cells 5, and a protrusion 11 is arranged at a position corresponding to the battery cell placement cavity 4 on the bottom plate 1, so that one end of the battery cell 5 can pass through the battery cell placement cavity 4 and contact the protrusion 11 on the bottom plate 1.

[0038] like Figure 1-5 As shown, the battery cell transfer pallet is described in detail. The pallet used in this embodiment can hold 14*14 battery cells 5. The side walls 2 of the pallet are enclosed on the outer peripheral edge of the bottom plate 1 to form a accommodating chamber. The accommodating chamber is a cavity structure with an opening on one side. A support frame 3 is arranged in the accommodating chamber. The support frame 3 includes a first support plate 31 and a second support plate 32. The second support plate 32 is located between the first support plate 31 and the bottom plate 1. A plurality of first through holes 41 are arranged on the first support plate 31, and a plurality of second through holes 42 are arranged on the second support plate 32 corresponding to the first through holes 41. The number of the first through holes 41 and the second through holes 42 is the same. The first through holes 41 and the second through holes 42 constitute a battery cell placement cavity 4. One end of the battery cell 5 passes through the first through hole 41 and the second through hole 42 in sequence to contact the protrusion 11 on the bottom plate 1. The first support plate 31 and the second support plate 32 are directly connected by bolts, and the first support plate 31 and the bottom plate 1 are connected by bolts, thereby realizing the fixation of the support frame 3 and the bottom plate 1.

[0039] like Figure 6As shown, the first support plate 31 includes a first frame body connected to each other, and the first through holes 41 are arranged on the first frame body. The first through holes 41 are arranged in an array along the first direction and the second direction. It should be noted that in this embodiment, the first direction is the length direction of the first frame body, and the second direction is the width direction of the first frame body. Exemplarily, in this embodiment, two adjacent rows of first through holes 41 arranged along the first direction are arranged in a plum blossom shape or a square shape, so that a diamond or square is formed between four adjacent first through holes 41, ensuring the accurate placement of the battery cell 5 and facilitating the automatic placement of the battery cell 5. Figure 7 As shown, the second support plate 32 includes a second frame, a support column, and a second through hole 42. The second through hole 42 is arranged on the second frame. The support column is arranged on the surface of the second frame away from the bottom plate 1, and is used to separate the first support plate 31 and the second support plate 32 to reduce the weight of the support frame 3, thereby reducing the load on the bottom plate 1 and reducing the deformation of the bottom plate 1. In some embodiments, the first frame and the first through hole 41 can be integrally injection molded. Since the battery cell transfer tray is made of plastic material or other materials with good insulation performance, even if the bottom of the battery cell 5 abuts against the protrusion 11 on the tray bottom plate 1, the insulation performance is still good, avoiding the occurrence of short circuits, and the safety performance of using the battery cell transfer tray is relatively high.

[0040] The adjacent battery cell placement cavities 4 are arranged at equal intervals, and the interval distance between adjacent battery cell placement cavities 4 is set to 10-20 mm. The setting of the interval distance allows the tray to place as many battery cells 5 as possible while ensuring the strength of the structure. For example, if the distance is set to be less than 10 mm, the distance between the battery cell placement cavities 4 is too close, and the load per unit area of ​​the bottom surface of the tray is too large, which can easily cause the tray to deform; if the interval distance is too large, for example, it is set to be greater than 25 mm, it is not conducive to placing more battery cells in a limited space, which will increase the number of trays used and increase production costs. Therefore, it is more appropriate to set the interval distance to between 10 and 20 mm.

[0041] It should be noted that the battery cell 5 provided in this embodiment is described by taking a cylindrical shape as an example. Of course, the operator can also set the battery cell 5 to any other shape according to the actual process requirements, which is not specifically limited here. When the battery cell 5 is a cylindrical battery cell, the inner diameter of the battery cell placement cavity 4 is 3~8mm larger than the inner diameter of the battery cell 5. The inner diameter of the battery cell placement cavity 4 is 3~8mm larger than the inner diameter of the battery cell 5. When the battery cell 5 is placed in the battery cell placement cavity 4, there is a gap between the battery cell 5 and the inner wall of the battery cell placement cavity 4. The battery cell 5 is taken out of or put into the battery cell placement cavity 4 of the tray. At the same time, the gap between the battery cell 5 and the inner wall of the battery cell placement cavity 4 is relatively small, which will not cause the placed battery cell 5 to shake, thereby ensuring the stability of the battery cell.

[0042] In some embodiments, a notch 43 is provided on the top of the cell placement cavity 4 for convenient cell placement. The top of the cell placement cavity 4 refers to the position of the cell placement cavity 4 close to the top surface of the support plate. Figure 4 As shown, specifically, the battery cell placement cavity 2 is composed of a first through hole 41 and a second through hole 42, a notch 43 is arranged on the first through hole 41, and the notch 43 is arranged at a position close to the top surface of the first support plate 31, and the cross-section of the notch 43 is V-shaped. The arrangement of the notch 43 exposes more side surfaces of the battery cell to the outside, making it convenient for a robot arm or an operator to clamp the battery cell 5 and remove the battery cell 5 from the battery cell placement cavity 4 of the tray.

[0043] The protrusion can increase the thickness of the bottom plate at the corresponding position of the battery cell placement cavity, such as Figure 5 It is shown that when no battery cell is placed, the height of the protrusion 11 is 1.5~4mm, and the cross-section of the protrusion is rectangular. A through avoidance hole 12 is provided at the position corresponding to the battery cell placement cavity 4 on the bottom plate 1. The inner diameter of the avoidance hole 12 is smaller than the inner diameter of the battery cell placement cavity 4, and the position where the avoidance hole 12 is set is within the range of the protrusion 11. Generally speaking, a pressure relief structure is provided at the bottom of the battery cell 5. The avoidance hole 12 of the tray bottom plate 1 can avoid the pressure relief structure. When the pressure inside the battery cell 5 is too high, the pressure relief structure can be opened and flow out through the avoidance hole 12 to avoid explosion, further ensuring the safety of the battery cell and personnel.

[0044] A transport hand groove 21 is provided on the outer surface of the side wall 2. The transport hand groove 21 is provided to facilitate a robot or an operator to clamp the pallet, thereby facilitating the transportation of the pallet.

[0045] The tray also includes a cover, which covers the opening of the battery tray to form a space for placing the battery cell 5 with the transport tray. The material of the cover includes but is not limited to metal and plastic. The top surface of the side wall 2 is provided with a step surface, and the lower bottom surface of the cover is provided with a panel. The side of the panel is tightly matched with the side of the step surface. By using the panel and the step surface, the cover can be buckled on the side wall 2 and is not easy to fall off, so as to prevent dust and foreign matter from entering and contaminating the battery cell.

[0046] In this embodiment, the plasticity of the material is utilized and an improved battery cell transfer tray is designed according to the direction of deformation caused by force. The above-mentioned technical solution is adopted, and a protrusion is provided in the opposite direction of the force on the bottom plate, that is, the position of the bottom plate facing the battery cell placement cavity. Specifically, the height of the protrusion is 2mm, and then the force deformation simulation is performed on the software. When the battery cell transfer tray is fully loaded with 196 battery cells, the deformation of the existing battery cell transfer tray after being subjected to the pressure of 196 battery cells is 3.8mm, which does not meet the requirement that the deformation of the bottom plate of the tray is ≤2mm when the battery cells are fully loaded. The deformation of the improved battery cell transfer tray after being subjected to the pressure of 196 battery cells is 1.7mm, which meets the requirement that the deformation of the bottom plate of the tray is ≤2mm when the battery cells are fully loaded. The utility model adopts a method of arranging a protrusion on the bottom plate at a position corresponding to the battery cell placement cavity. The setting of the protrusion can increase the thickness of the bottom plate at the position corresponding to the battery cell placement cavity. When the battery cell is placed in the battery cell placement cavity, the gravity of the battery cell acts on the protrusion of the bottom plate. The setting of the protrusion can increase the bearing capacity of the bottom plate corresponding to the battery cell placement cavity and reduce the deformation of the bottom plate of the battery cell transfer tray, thereby ensuring that the bearing capacity is increased by 55% and saving more than 15% of the cost.

The above embodiments and the utility model content of the specification only describe the principles or specific cases of the utility model.
