Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0037] In high-power applications such as electric vehicles, battery applications involve three levels: individual battery cells, battery modules, and battery packs. Battery modules are formed by electrically connecting a certain number of individual battery cells and placing them in a frame to protect them from external impacts, heat, and vibration. Battery packs represent the final state of the battery system installed in an electric vehicle. Currently, most battery packs are made by assembling a battery management system (BMS), thermal management components, and various control and protection systems onto one or more battery modules. With technological advancements, the battery module level can be omitted, meaning that battery packs can be formed directly from individual battery cells. This improvement increases the gravimetric and volumetric energy density of the battery system while significantly reducing the number of components. The battery mentioned in this invention includes either a battery module or a battery pack.

[0038] In this invention, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and this invention is not limited to these types. The battery cell may be cylindrical, flat, cuboid, or other shapes, and this invention is not limited to these shapes either. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, cuboid / square battery cells, and pouch battery cells, and this invention is not limited to these types either.

[0039] A battery cell includes a casing, electrode assembly, and electrolyte. The electrode assembly and electrolyte are housed within the casing. The electrode assembly consists of a positive electrode, a negative electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the positive and negative electrode plates. The positive electrode includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector. The current collector without the positive active material layer protrudes beyond the current collector with the positive active material layer, serving as the positive electrode tab. Taking a lithium-ion battery as an example, the material of the positive current collector can be aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector. The current collector without the negative active material layer protrudes beyond the current collector with the negative active material layer, serving as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon, etc. To ensure that a large current can be passed without melting, there are multiple positive electrode tabs stacked together, and there are multiple negative electrode tabs stacked together.

[0040] There are no particular limitations on the aforementioned separator membrane; any known multi-channel separator membrane with electrochemical and chemical stability can be selected, such as a single-layer or multi-layer film of one or more of glass fiber, non-woven fabric, polyethylene, polypropylene, and polyvinylidene fluoride. The material of the separator membrane can be polypropylene (PP) or polyethylene (PE), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; this embodiment of the invention is not limited to these.

[0041] Of course, a single battery cell may not necessarily include electrolyte.

[0042] To meet diverse power demands, a battery can comprise multiple individual cells, which can be connected in series, parallel, or a combination of both. Optionally, multiple individual cells can first be connected in series, parallel, or a combination to form a battery module, and then these battery modules can be connected in series, parallel, or a combination to form a battery. In other words, multiple individual cells can directly form a battery, or they can first be assembled into battery modules or battery packs, and then the battery modules can be assembled into a battery. The battery is then further installed in the electrical device to provide power to it.

[0043] The development of battery technology must consider multiple design factors simultaneously, such as performance parameters like energy density, cycle life, discharge capacity, and charge / discharge rate, as well as safety. Faced with different design factors and safety requirements, battery cells are constantly iterating and upgrading, and correspondingly, their size is also continuously changing.

[0044] When the size of the battery cell is adjusted, the related equipment used to manufacture the cell also needs to be adjusted. For example, during the production process, the battery cells need to be moved between different workstations using pallets. The pallets restrain the battery cells, enabling precise positioning and safety protection, preventing displacement or damage during transportation, thereby improving overall production efficiency and product quality.

[0045] In existing technologies, conventional trays are often only compatible with one type of battery cell, resulting in poor compatibility. This means that when a battery cell is changed, the tray also needs to be changed. Customizing new trays requires significant time and cost. For example, a single changeover may require the creation of three different tray molds, which are expensive, and the inventory of multiple specialized trays takes up space and increases management complexity.

[0046] In existing technologies, some battery trays have adjustable dimensions to accommodate different battery cell models, thus improving compatibility to some extent. However, these existing trays typically clamp the battery cells in place. This clamping method relies on radial force, which concentrates at the clamping point, creating localized stress that can damage the battery cells.

[0047] To solve the above problems, refer to Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a battery cell restraint tray. The battery cell restraint tray includes a tray body 10, a first support 30, a support rod 40, and a pressure plate 50.

[0048] The tray body 10 is used to support the battery cell 20. During the production and processing, the battery cell 20 is carried and fixed by the tray body 10 and moved between different workstations. Those skilled in the art can set the shape and material of the tray according to actual needs. For example, in terms of shape, a square tray is preferred to facilitate transport and movement in a streamlined manner. In terms of material, materials such as plastic and metal can be selected for fabrication.

[0049] The first support 30 is detachably connected to the pallet body 10. Those skilled in the art can customize the shape and material of the first support 30 according to actual needs. Preferably, the shape and material of the first support 30 are the same as those of the pallet body 10. Those skilled in the art can customize the detachable connection method between the first support 30 and the pallet body 10 according to actual needs. For example, threaded connection, snap-fit, etc.

[0050] The connection position between the first support 30 and the tray body 10 is configured to be adjustable in any direction perpendicular to the first direction D1, wherein the first direction D1 is the vertical direction.

[0051] Those skilled in the art can adjust the connection position between the first support 30 and the tray body 10 according to actual needs. For example, multiple snap-fit ​​holes can be provided on the tray body 10, and the first support 30 can be positioned in any one of these holes. By selecting different snap-fit ​​holes to position the first support 30, the connection position between the first support 30 and the tray body 10 can be adjusted.

[0052] A support rod 40 is disposed on the first support 30. The support rod 40 is used to connect the pressure plate 50 and the first support 30, and forms a certain space between the pressure plate 50 and the first support 30 to accommodate the battery cell 20 to be fixed. Those skilled in the art can configure the shape of the support rod 40 according to actual needs; for example, the support rod 40 can be configured as a cuboid or a cylinder. Those skilled in the art can configure the connection method between the support rod 40 and the first support 30 according to actual needs; for example, the support rod 40 and the first support 30 can be integrally formed, or the support rod 40 and the first support 30 can be configured as a detachable connection.

[0053] The pressure plate 50 is located on one side of the tray body 10 along the first direction D1. In this embodiment of the invention, the pressure plate 50 is disposed above the tray body 10. The pressure plate 50 is connected to the support rod 40, and the distance between the pressure plate 50 and the tray body 10 is configured to be adjustable to press the battery cell 20.

[0054] Those skilled in the art can set the shape of the pressure plate 50 according to actual needs, such as square or round.

[0055] Those skilled in the art can adjust the distance between the pressure plate 50 and the pallet body 10 according to actual needs. For example, the pressure plate 50 can be connected to the support rod 40 by a pin, so that the pressure plate 50 can rotate around the axis of the pin and flip over, thereby adjusting the distance between the pressure plate 50 and the pallet body 10.

[0056] In this embodiment of the invention, the cell restraint tray is mainly used to fix the square cell 20. The square cell 20 has a cuboid structure, including side surfaces and a top surface and a bottom surface that are arranged opposite each other. The side surfaces can be simply distinguished into large side surfaces and small side surfaces based on their area. The large side surfaces are those corresponding to the length and height directions of the cell 20, while the small side surfaces are those corresponding to the width and height directions of the cell 20.

[0057] When placing the square battery cell 20 on the battery cell restraint tray, it is preferable that the large side of the battery cell 20 contacts the battery cell restraint tray. For example, one large side of the battery cell 20 contacts the tray body 10, and the other large side of the battery cell 20 is pressed down by the pressure plate 50.

[0058] Compared to existing clamping methods, the pressure plate 50 used to clamp and fix the battery cell 20 provides a more uniform pressure distribution and a larger contact area between the pressure plate 50 and the battery cell 20. This increases the contact area, reducing pressure per unit area and minimizing pressure, scratches, or indentations on the surface of the battery cell 20. Due to the uniform pressure distribution and large contact area, the battery cell 20 is less prone to displacement or loosening when accidentally subjected to external forces during transportation, resulting in greater stability. Furthermore, the clamping method is compatible to a certain extent with battery cells 20 of different sizes in the first direction D1, improving compatibility.

[0059] With the connection position of the first support 30 relative to the pallet body 10 adjustable, the support rod 40 and pressure plate 50 on the first support 30 can be adjusted along with the first support 30 relative to the pallet body 10. Thus, when dealing with a different type of battery cell 20, the relative pressing position of the pressure plate 50 can be adjusted, thereby achieving compatibility with different models of battery cells 20, effectively improving pallet compatibility and utilization, and enhancing the adaptability of the production line. Compared to replacing the entire pallet, this method only requires simple adjustments to complete the adaptation to the new model of battery cell 20, resulting in faster changeover speed, higher efficiency, and lower cost, without requiring a large number of personnel to handle pallets. Furthermore, no additional space is needed to store old pallets, reducing the complexity of warehousing and management.

[0060] In actual use, simply place the battery cell 20 on the tray body 10, adjust the distance between the pressure plate 50 and the tray body 10 to press the battery cell 20 firmly, and then use a streamlined transport to transport the battery cell restraint tray and the battery cell 20 to various workstations for corresponding operations. When the production of the current model of battery cell 20 is completed and it is necessary to process battery cells 20 of different sizes, simply adjust the connection position between the first support 30 and the tray body 10 to achieve adaptation.

[0061] The battery cell restraint tray of this utility model, on the one hand, uses a pressure plate 50 to press and fix the battery cell 20, resulting in a more uniform pressure distribution and a larger contact area between the pressure plate 50 and the battery cell 20. This improves the stability of the tray, reduces the possibility of damage to the battery cell 20, and ensures high processing quality of the battery cell 20. On the other hand, by adjusting the connection position between the first support 30 and the tray body 10, the relative pressing position of the pressure plate 50 can be adjusted, thereby achieving compatibility with different models of battery cells 20. This effectively improves the compatibility and utilization rate of the tray and enhances the adaptability of the production line. It results in fast changeover speed, high efficiency, and low cost, while reducing the complexity of warehousing and management.

[0062] Preferably, the square pallet includes a length direction and a width direction perpendicular to the first direction D1, wherein the length direction is the second direction D2 and the width direction is the third direction D3. When the pallet body 10 aligns with the streamline, it aligns with the streamline through both sides of the second direction D2 and moves along the third direction D3. It is understood that the third direction D3 is perpendicular to both the first direction D1 and the second direction D2.

[0063] Reference Figure 1 and Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, guide wheels 161 are provided on the tray body 10. Preferably, the tray body 10 is square, and four guide wheels 161 are provided, respectively located at the four corners of the tray body 10. In this way, the guide wheels 161 can cooperate with the guide rails on the flow line or workstation to ensure that the battery cell 20 can be accurately positioned, thereby improving the processing quality of the battery cell 20.

[0064] Reference Figure 1 and Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, the tray body 10 is provided with U-shaped blocks 162. Preferably, four U-shaped blocks 162 are provided. The U-shaped blocks 162 are located on one side of the guide roller 161. The U-shaped blocks 162 have an overall "U" shape structure, which can cooperate with the shift forks on the corresponding workstations to ensure that the battery cell 20 can be accurately positioned and improve the processing quality of the battery cell 20.

[0065] Reference Figure 1 and Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, the tray body 10 is provided with wear-resistant strips 163. By providing wear-resistant strips 163, the wear-resistant strips 163 can cooperate with the streamline, which increases the friction and reduces the wear of the tray, thus extending the service life of the tray. Preferably, the wear-resistant strips 163 are only provided on both sides of the tray body 10 in contact with the streamline, that is, on both sides of the tray body 10 along the second direction D2.

[0066] Reference Figure 1 and Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, the tray body 10 is provided with anti-collision members 164. By providing anti-collision members 164, hard contact between the tray body 10 and the flow line or instruments at the corresponding workstation is avoided, thereby reducing the possibility of wear and displacement of the battery cell 20 due to force. Preferably, the anti-collision members 164 are springs, and two sets of anti-collision members 164 are provided. The two sets of anti-collision members 164 are respectively provided on both sides of the moving direction of the tray body 10, that is, on both sides of the tray body 10 along the third direction D3. Each set is provided with three anti-collision members 164, and the three anti-collision members 164 are arranged sequentially at intervals along the second direction D2.

[0067] Reference Figure 1 and Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, the tray body 10 is provided with positioning holes 165. The positioning holes 165 are used to cooperate with components on the workstation to achieve precise positioning, so as to perform corresponding operations on the battery cell 20 and ensure high processing quality of the battery cell 20. Those skilled in the art can set the position and size of the positioning holes 165 according to actual needs.

[0068] Reference Figure 1 and Figure 2 As shown, in some embodiments, the battery cell restraint tray of this utility model is provided with two sets of first supports 30, support rods 40, and pressure plates 50 to fix two battery cells 20 on a tray body 10. Preferably, each set has two of each component, that is, one battery cell 20 is pressed by two pressure plates 50 to ensure stability.

[0069] Reference Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, the tray body 10 is provided with a first sliding groove 11, and a first support 30 is disposed in the first sliding groove 11. The first support 30 and the first sliding groove 11 slide in cooperation along the second direction D2.

[0070] By setting the first slide groove 11, it is possible to provide sliding guidance for the first support 30, increase structural stability, and reduce the size of the pallet in the first direction D1, thereby improving space utilization.

[0071] When the large side of the battery cell 20 contacts the tray body 10, the adjustable pressing distance of the pressure plate 50 allows for the adaptation of battery cells 20 with different dimensions in the width and height directions. Building upon this, adaptation for battery cells 20 with different dimensions in the length direction needs to be considered. Therefore, by configuring the first support 30 and the first slide groove 11 to slide along the second direction D2, the relative pressing position of the pressure plate 50 along the second direction D2 can be adjusted, thereby achieving adaptation for battery cells 20 of different lengths. This effectively improves the compatibility and utilization rate of the tray and enhances the adaptability of the production line.

[0072] Preferred, refer to Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, a plurality of first fixing holes 112 are arranged at uniform intervals along the second direction D2 on the bottom of the first sliding groove 11. A first adjustment hole 31 is provided on the first support 30, and a first fixing member 101 is provided in the first adjustment hole 31. After the position of the first support 30 along the second direction D2 is adjusted, the first fixing member 101 is connected to the corresponding first fixing hole 112 to fix the first support 30.

[0073] Preferably, the first fixing hole 112 is a threaded hole; the first adjusting hole 31 is a strip-shaped hole, the length of which is parallel to the second direction D2; and the first fixing member 101 is a bolt. Preferably, the first support 30 is square, and each of the four corners of the first support 30 is provided with a first adjusting hole 31. In this way, the adjustment and fixing between the first support 30 and the tray body 10 can be achieved conveniently and quickly.

[0074] Reference Figure 2 and Figure 3 As shown, in some embodiments of the battery cell restraint tray of this utility model, the bottom of the first groove 11 is provided with a clearance hole 111 penetrating the tray body 10. The support rod 40 slidably passes through the first support 30 and the clearance hole 111 along the first direction D1, and the support rod 40 and the clearance hole 111 slide in cooperation along the second direction D2. Those skilled in the art can set the connection method of the support rod 40 and the pressure plate 50 according to actual needs. For example, the support rod 40 and the pressure plate 50 can be detachably connected or integrally formed.

[0075] This structure, on one hand, allows for adjustment of the clamping distance between the pressure plate 50 and the pallet body 10 by sliding the support rod 40 relative to the first support 30 along the first direction D1. Compared to the flip-and-press method, this lifting and pressing method has a wider range of compatibility. On the other hand, the clearance hole 111 avoids the support rod 40, ensuring that the support rod 40 does not interfere with the pallet body 10 when sliding relative to the first groove 11.

[0076] Those skilled in the art can set the driving method of the support rod 40 along the first direction D1 according to actual needs. For example, a motor, cylinder or other driver can be set on the pallet body 10 to achieve driving, or a motor, cylinder or other driver can be set on the streamline or corresponding work station to achieve driving.

[0077] To reduce the overall weight of the cell restraint tray, refer to Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments of the battery cell restraint tray of this utility model, the driver of the support rod 40 is set in the streamline or corresponding work station.

[0078] Correspondingly, the support rod 40 is fitted with a guide sleeve 60, which is used to guide the movement of the support rod 40 along the first direction D1 and increase the structural stability. The guide sleeve 60 is fixed to the first support 30, and a portion of the guide sleeve 60 passes through the clearance hole 111.

[0079] In the first direction D1, the end of the support rod 40 away from the pressure plate 50 is connected to the limiting block 41. The support rod 40 is fitted with an elastic element 70, and in the first direction D1, both ends of the elastic element 70 abut against the guide sleeve 60 and the limiting block 41, respectively. Preferably, the elastic element 70 is a spring, to further increase the reliability of the fixation by utilizing the elastic force of the spring.

[0080] Thus, when the pallet moves to the corresponding work station, the driving end of the corresponding driver abuts against the limiting block 41, thereby overcoming the force of gravity and the elastic force of the elastic element 70, and lifting the pressure plate 50 so that the pressure plate 50 is separated from the battery cell 20, so as to facilitate the corresponding operation.

[0081] After the corresponding operation is completed, for example, after the battery cell 20 is replaced, the drive end of the driver separates from the limit block 41. Under the action of gravity and the elastic force of the elastic element 70, the pressure plate 50 presses down and tightens the battery cell 20.

[0082] Reference Figure 1 and Figure 2 As shown, in some embodiments of the battery cell restraint tray of this utility model, the support rod 40 can rotate about a first direction D1 relative to the first support 30. Preferably, the rotation drive of the support rod 40 is also achieved by a streamlined or corresponding workstation driver. Preferably, the driver is set as a rotary lifting cylinder, which combines rotation and lifting functions to improve space utilization. In this way, when the tray moves to the corresponding workstation, the pressure plate 50 is lifted by the rotary cylinder, so that the pressure plate 50 can rotate with the support rod 40 to avoid obstacles and facilitate the loading and unloading of the battery cells 20.

[0083] Reference Figure 6 As shown, in some embodiments of the battery cell restraint tray of this utility model, the pressure plate 50 has a first end 51 and a second end 52 along its own length. The first end 51 is used to press the battery cell 20.

[0084] Preferably, a rubber block 90 is provided on the side of the first end 51 facing the tray body 10. In this way, the rubber block 90 effectively increases the frictional force on the battery cell 20, preventing displacement of the battery cell 20 and allowing it to be stably fixed on the battery cell restraint tray for transport along the conveyor belt. Of course, in some other embodiments, other materials can be used to achieve a similar effect.

[0085] Preferably, the rubber block 90 is detachably connected to the first end 51 via bolts and screw holes, so that a new rubber block 90 can be replaced when the rubber block 90 wears out.

[0086] When the pressure plate 50 is lifted, the distance between the rubber block 90 and the tray body 10 along the first direction D1 is the first distance H1; when the pressure plate 50 presses the battery cell 20, the distance between the rubber block 90 and the tray body 10 along the first direction D1 is the second distance H2. Understandably, the second distance H2 is less than the first distance H1.

[0087] Reference Figure 5 As shown, in some embodiments of the battery cell restraint tray of this utility model, the limiting block 41 is provided with a docking hole 411 so that the driving end of the corresponding driver can dock and cooperate to realize the lifting and rotating drive of the pressure plate 50.

[0088] Reference Figure 7 and Figure 8 As shown, in some embodiments of the battery cell restraint tray of this utility model, a first limiting member 32 and a second limiting member 33 are provided on the first support 30. The first limiting member 32 is located on one side of the support rod 40 along the third direction D3, and the second limiting member 33 is located on one side of the support rod 40 along the second direction D2. By providing two limiting members, the pressure plate 50 is snapped and fixed.

[0089] Specifically, in the first direction D1, the end face of the first limiting member 32 away from the pallet body 10 is recessed to form a first limiting groove 321, which penetrates the first limiting member 32 along the third direction D3. In the first direction D1, the end face of the second limiting member 33 away from the pallet body 10 is recessed to form a second limiting groove 331, which penetrates the second limiting member 33 along the second direction D2.

[0090] The first limiting groove 321 is configured to engage with the pressure plate 50 when its length direction is the third direction D3, and the second limiting groove 331 is configured to engage with the pressure plate 50 when its length direction is the second direction D2. Preferably, the second end 52 of the pressure plate 50 engages with the corresponding limiting groove. Thus, by checking whether the two limiting members engage with the pressure plate 50, it can be determined whether the pressure plate 50 has rotated to the correct position, effectively increasing the stability and reliability of the structure.

[0091] Furthermore, refer to Figure 8As shown, the first limiting groove 321 has two opposite groove walls arranged along the second direction D2, each with a first guide slope 322. The distance between the two first guide slopes 322 gradually decreases along the second direction D2 towards the bottom of the first limiting groove 321. Similarly, the second limiting groove 331 has two opposite groove walls arranged along the third direction D3, each with a second guide slope 332. The distance between the two second guide slopes 332 gradually decreases along the third direction D3 towards the bottom of the second limiting groove 331. This allows the second end 52 of the pressure plate 50 to more easily enter the corresponding limiting groove.

[0092] Reference Figure 1 and Figure 9 As shown, in some embodiments of the battery cell restraint tray of this utility model, the tray body 10 is provided with a second sliding groove 13, and a plurality of second supports 80 are provided in the second sliding groove 13. Each second support 80 and the second sliding groove 13 are slidably engaged along a second direction D2, and each second support 80 and the tray body 10 are detachably connected. The second support 80 is configured to support the battery cell 20.

[0093] By setting the second support 80 and the second slide groove 13 to slide along the second direction D2, the relative pressing position of the second support 80 along the second direction D2 can be adjusted, thereby achieving adaptation to different lengths and models of battery cells 20, effectively improving the compatibility and utilization of the tray, and enhancing the adaptability of the production line.

[0094] By setting the second slide groove 13, it is possible to provide sliding guidance for the second support 80, increase structural stability, and reduce the size of the pallet in the second direction D2, thereby improving space utilization.

[0095] Preferred, refer to Figure 1 and Figure 9 As shown, in some embodiments of the battery cell restraint tray of this utility model, the bottom of the second groove 13 is provided with a plurality of second fixing holes 131 evenly spaced along the second direction D2. The second support 80 is provided with a second adjustment hole 81, and a second fixing member 102 is provided in the second adjustment hole 81. After the position of the second support 80 along the second direction D2 is adjusted, the second fixing member 102 is connected to the corresponding second fixing hole 131 to fix the second support 80.

[0096] Preferably, the second fixing hole 131 is a threaded hole; the second adjusting hole 81 is a strip-shaped hole, the length of which is parallel to the second direction D2; and the second fixing member 102 is a bolt. Preferably, the second support 80 is square, and the second support 80 is provided with two second adjusting holes 81, which are spaced apart along the third direction D3. In this way, the adjustment and fixing between the second support 80 and the tray body 10 can be achieved conveniently and quickly.

[0097] Preferred, refer to Figure 10 As shown, in some embodiments of the battery cell restraint tray of this utility model, a rubber block 90 is provided on the side of the second support 80 opposite to the tray body 10 along the first direction D1. Thus, by providing the rubber block 90, the frictional force on the battery cell 20 can be effectively increased, preventing displacement of the battery cell 20 and allowing the battery cell 20 to be stably fixed on the battery cell restraint tray for transport along the conveyor belt. Of course, in some other embodiments, other materials can also be used to achieve a similar effect.

[0098] Preferably, the rubber block 90 and the second support 80 are detachably connected by bolts and screw holes so that when the rubber block 90 wears out, a new rubber block 90 can be replaced.

[0099] Reference Figure 1 , Figure 9 and Figure 10 As shown, in some embodiments of the battery cell restraint tray of the present invention, the tray body 10 is provided with a clearance channel 14 that penetrates the tray body 10, and in the third direction D3, the second slide groove 13 is located between the clearance channel 14 and the first support 30.

[0100] The clearance channel 14 is mainly used to avoid welding instruments so that when the battery cell restraint tray is transferred to the welding work area, the welding instruments on the welding work area can weld the tabs 21 and the adapter plates of the battery cell 20. Accordingly, when setting up the battery cell 20, the tabs 21 of the battery cell 20 should be oriented towards the clearance channel 14.

[0101] Preferred, refer to Figure 10 As shown, in some embodiments of the battery cell restraint tray of this utility model, the avoidance channel 14 is provided with a third guide slope 141 along the first direction D1 away from the channel opening of the pressure plate 50. The third guide slope 141 mainly serves to protect and guide, avoiding hard contact between the welding instrument and the tray body 10, and extending the service life of the tray and the instrument.

[0102] Reference Figure 9 and Figure 10As shown, in some embodiments of the battery cell restraint tray described in this utility model, the bottom of the second groove 13 is provided with a weight-reducing hole 132. And / or, in the first direction D1, a weight-reducing groove 15 is provided on the side of the tray body 10 away from the pressure plate 50. Thus, there are a total of three cases.

[0103] The first type: a weight-reducing hole 132 is provided only at the bottom of the second slide groove 13. The second type: a weight-reducing groove 15 is provided only on the side of the pallet body 10 away from the pressure plate 50. The third type: both the weight-reducing hole 132 and the weight-reducing groove 15 are provided.

[0104] By setting up this structure, the weight of the cell restraint tray can be effectively reduced, thereby saving the energy required for tray circulation and reducing production and processing costs.

[0105] Working principle:

[0106] When setting up the battery cell 20, the tray body 10 is first positioned on the flow line. A rotary lifting cylinder is used to lift the support rod 40 and pressure plate 50 and rotate them 90°. Then, the battery cell 20 is placed on the second support 80. After the battery cell 20 is in place, the rotary lifting cylinder is used to rotate the support rod 40 and pressure plate 50 back to their original positions. Under the action of the elastic element 70 and gravity, the pressure plate 50 presses the battery cell 20 firmly. Subsequently, the tray and battery cell 20 are transported along the flow line.

[0107] When the tray and battery cell 20 enter the ultrasonic welding station, the tray and battery cell 20 are moved using a shift fork in conjunction with the U-shaped block 162 on the tray. After the tray and battery cell 20 are in place, the support rod 40 and pressure plate 50 are lifted and rotated 90° using a rotary lifting cylinder. A sensor detects whether the second end 52 of the pressure plate 50 is engaged and fixed with the second limiting groove 331 of the second limiting member 33, thereby determining whether the pressure plate 50 has rotated into place. After the detection is complete, the ultrasonic welding instrument welds the electrode tab 21 and the adapter plate of the battery cell 20.

[0108] When the production of the current model of battery cell 20 is completed, and it is necessary to process battery cells 20 of different sizes, it is only necessary to adjust the position of the first support 30 and the second support 80 relative to the tray body 10 to achieve adaptation.

[0109] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0110] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0111] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
