Description

Technical Field

[0001] The invention belongs to the technical field of blister trays, and specifically designs a blister tray for carrying integrated busbars. Background Art

[0002] In the field of new energy, in order to ensure the safe use of battery modules, an integrated busbar is set on the battery module to collect parameters such as the voltage and temperature of the battery cell. The existing integrated busbar generally includes a bracket, a collection component (such as FPC) and an aluminum bar arranged on the bracket, wherein the bracket is provided with multiple exhaust holes, and the exhaust holes are arranged opposite to the pressure relief valve of the battery cell.

[0003] In the prior art, when the integrated busbar is transported, in order to protect the integrated busbar, the integrated busbar is placed in a sunken anti-static pearl cotton, and multiple pearl cottons are stacked and fixed before being transported. Since the pearl cotton is soft and easily deformed, multiple pearl cottons cannot be positioned relative to each other after being stacked, which is not conducive to the fixation and transportation of the stacked pearl cotton. After the integrated busbar is placed in the pearl cotton, the integrated busbar can move in the pearl cotton, and the movable integrated busbar is prone to damage its electronic components.

[0004] The prior art has pallets that are convenient for product transportation and can protect products. The products transported by such pallets are short, so the length of the pallet will not be set very long. However, since the length of the integrated busbar is generally long, and some integrated busbars are even up to 2 meters long, the existing pallets cannot be used directly to transport the integrated busbar. Furthermore, among the existing pallets, taking the pallet for transporting soft-pack square batteries as an example, in order to protect the batteries during transportation, the shape and size of the accommodating grooves in the pallet are generally adapted to the shape and size of the batteries, so that the batteries can be reliably stuck in the accommodating grooves. If the size of the pallet is directly lengthened to transport the batteries, in order to ensure the rigidity of the pallet and avoid squeezing the product due to insufficient rigidity and deformation of the pallet, the pallet needs to be made thicker. In this way, the volume of the pallet is larger and will take up space, which will result in a small number of pallets loaded under the same transportation volume and low transportation efficiency. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a blister tray for carrying integrated busbars.

[0006] To achieve the above objectives, the present invention discloses a blister tray for carrying an integrated busbar, comprising a support plate, an inner annular vertical plate erected from the edge of the support plate, an annular horizontal plate extending horizontally outward from the top of the inner annular vertical plate, and an outer annular vertical plate extending downward from the outer edge of the annular horizontal plate; the support plate, the inner annular vertical plate, the annular horizontal plate and the outer annular vertical plate are integrally formed by a blister process, and the inner annular vertical plate, the annular horizontal plate and the outer annular vertical plate form an inner cavity;

[0007] The support plate is used to support the integrated busbar, and a plurality of positioning columns are arranged on the support plate, and the plurality of positioning columns are arranged at intervals along the length direction of the support plate, and each positioning column is limitedly matched with an exhaust hole of the integrated busbar bracket to position the integrated busbar;

[0008] The height of the positioning column is greater than the thickness of the integrated busbar, and the top surface of the positioning column is a supporting surface for supporting the supporting plate of the adjacent blister tray;

[0009] The connecting portion of the annular horizontal plate and the outer annular vertical plate is recessed toward the inner cavity to form a first groove, and a support block is formed in the inner cavity, and the bottom surface of the support block is pressed against the annular horizontal plate of the adjacent blister tray;

[0010] There are a plurality of the first grooves, and the plurality of first grooves are arranged at intervals along the connecting positions of the annular horizontal plate and the outer annular vertical plate.

[0011] Preferably, a conductive row avoidance groove is provided at the end of the support plate, and the depth of the conductive row avoidance groove is greater than the thickness of the support plate, thereby forming a protruding first pressure block at the bottom of the support plate, and the bottom of the first pressure block is used to press and cooperate with the integrated busbar bracket on the adjacent blister tray.

[0012] Preferably, the depth of the conductive row avoidance groove is smaller than the height of the inner annular vertical plate.

[0013] Preferably, the difference between the depth of the conductive row avoidance groove and the height of the inner annular vertical plate is 1 mm to 3 mm.

[0014] Preferably, the conductive exhaust slot is arranged opposite to the first groove.

[0015] Preferably, the support plate is further provided with protruding second pressing blocks at two ends in the length direction thereof, and the bottom of the second pressing block is flush with the bottom of the first pressing block.

[0016] Preferably, the spacing between two adjacent first grooves is unequal so that the first grooves and the support blocks of two adjacent blister trays are staggered; and / or

[0017] The positioning columns are hollow columns that arch upwards, and the spacing between two adjacent positioning columns is unequal, so that the top surfaces and bottom surfaces of the positioning columns of two adjacent blister trays are staggered.

[0018] Preferably, the support plate is provided with a plurality of spring-piece spring-piece avoidance grooves, and the plurality of spring-piece spring-piece avoidance grooves are spaced apart along the length direction of the support plate.

[0019] Preferably, at least part of the spring-clip avoidance grooves are connected to form a second groove, the depth of the second groove is greater than the thickness of the support plate, thereby forming a protruding third pressure block at the bottom of the support plate, and the bottom surface of the third pressure block is used to press fit with the integrated busbar aluminum bar on the adjacent blister tray.

[0020] Preferably, a component avoidance groove is provided on the support plate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] By setting a plurality of positioning columns on the support plate, the plurality of positioning columns are arranged at intervals along the length direction of the support plate, and each positioning column is limited in cooperation with an exhaust hole of the integrated busbar bracket, after the integrated busbar is placed on the support plate, the exhaust hole cooperates with the positioning column to limit the horizontal activity of the integrated busbar, thereby avoiding the horizontal movement of the integrated busbar during transportation, which causes the integrated busbar to be damaged by impact. By setting a plurality of positioning columns to cooperate with the plurality of exhaust holes of the integrated busbar, the vertical range of motion of the integrated busbar will be limited by the restriction of the plurality of positioning columns, which can reduce the damage caused by the jumping of the integrated busbar. The vertical direction of the integrated busbar is limited by the horizontal limit of the positioning column and the cooperation of the plurality of positioning columns, so that the integrated busbar is basically fixed on the support plate, which can greatly alleviate the problem that the integrated busbar cannot be fixed during transportation and the electronic components are easily damaged.

[0023] The top surface of the positioning column is a supporting surface, which is used to support the support plate of the adjacent blister tray. The connecting portion of the annular horizontal plate and the outer annular vertical plate is recessed into the inner cavity, thereby forming a support block in the inner cavity. The bottom surface of the support block is pressed against the annular horizontal plate of the adjacent blister tray. In this way, during the transportation process, two adjacent blister trays can be stacked (the support plate of the upper blister tray is pressed on the positioning column of the lower blister tray, and its support block is pressed on the annular horizontal plate of the lower blister tray), which can improve the transportation efficiency.

[0024] Since the blister tray obtained by the blister process is thin and long, the rigidity of the blister tray is insufficient, especially in the middle of the support plate. Therefore, the column of the present invention is not only used to position and fix the integrated busbar, but also can be used to support the support plate of the upper blister tray to prevent the support plate from sinking downward and damaging the electronic components on the integrated busbar. Furthermore, the height of the positioning column is greater than the thickness of the integrated busbar, which can further prevent the support plate from damaging the electronic components on the integrated busbar;

[0025] Since the brackets and FPC of the integrated busbar have certain deformation capabilities, the present invention makes full use of this feature, and the thickness of the blister tray can be set relatively thin, and it is not necessary to set it thicker like the existing tray to ensure its rigidity. In this way, the number of trays loaded is large under the same handling volume, and the handling efficiency is high. Since the brackets of some existing integrated busbars are also formed by the blister process, the blister tray of the present invention is formed by the blister process, and for manufacturers, the same equipment can be shared to reduce manufacturing costs.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment is mainly aimed at the integrated busbar blister tray that can be used to transport. In order to facilitate the explanation of the blister tray, the structure of the integrated busbar 1 is first introduced. The existing integrated busbar includes a bracket 11, a collection component 12 (such as FPC) and an aluminum bar 13 arranged on the bracket, wherein a mounting groove 111 for mounting the aluminum bar is provided on the bracket, and a spring 112 is provided at the bottom of the mounting groove. The spring is used to support the aluminum bar so that it does not contact the battery cell pole first. When the aluminum bar needs to be welded to the battery cell pole, the spring is pressurized (the spring is stretched) until the aluminum bar contacts the battery cell pole, and then welding can be performed. The bracket is also provided with a plurality of exhaust holes 113, and the exhaust holes are arranged opposite to the pressure relief valve of the battery cell. The aluminum bars located at both ends of the bracket and extending outward are conductive bars 131 connected to the outside world.

[0038] A blister tray for carrying an integrated busbar includes a support plate 2, an inner annular vertical plate 3 erected from the edge of the support plate 2, an annular horizontal plate 4 extending horizontally outward from the top of the inner annular vertical plate 3, and an outer annular vertical plate 5 extending downward from the outer edge of the annular horizontal plate 4; the support plate 2, the inner annular vertical plate 3, the annular horizontal plate 4 and the outer annular vertical plate 5 are integrally formed by a blister process. Since some existing integrated busbar brackets are also formed by a blister process, this blister tray is formed by a blister process, and for manufacturers, the same equipment can be shared to reduce manufacturing costs. The inner annular vertical plate 3, the annular horizontal plate 4 and the outer annular vertical plate 5 form an inner cavity.

[0039] Among them, the support plate 2 is used to support the integrated busbar, and a plurality of positioning columns 21 are provided on the support plate 2. The plurality of positioning columns 21 are arranged at intervals along the length direction of the support plate 2, and each positioning column 21 is limitedly matched with an exhaust hole of the integrated busbar bracket to position the integrated busbar; the height of the positioning column 21 is greater than the thickness of the integrated busbar, and the top surface of the positioning column 21 is a supporting surface 211, which is used to support the support plate 2 of the adjacent blister tray. The connecting position of the annular horizontal plate 4 and the outer annular vertical plate 5 is partially recessed into the inner cavity to form a first groove 51, and a support block 52 is formed in the inner cavity, and the bottom surface of the support block 52 is pressed against the annular horizontal plate 4 of the adjacent blister tray; there are a plurality of first grooves 51, and the plurality of first grooves 51 are arranged at intervals along the connecting position of the annular horizontal plate 4 and the outer annular vertical plate 5. The above arrangement of the positioning column 21 and the support block 52 has the following advantages: First, after the integrated busbar is placed on the support plate 2, the cooperation between the exhaust hole and the positioning column 21 can limit the horizontal activity of the integrated busbar, thereby preventing the integrated busbar from moving horizontally during transportation, which may cause the integrated busbar to be damaged by impact. By setting multiple positioning columns 21 to cooperate with multiple exhaust holes of the integrated busbar, the vertical range of motion of the integrated busbar will be limited by the restriction of multiple positioning columns 21, which can reduce the damage caused by the jumping of the integrated busbar. The vertical direction of the integrated busbar is restricted by the horizontal limit of the positioning column 21 and the cooperation of multiple positioning columns 21, so that the integrated busbar is basically fixed on the support plate 2, which can greatly alleviate the problem that the integrated busbar cannot be fixed during transportation and the electronic components are easily damaged. Second, the top surface of the positioning column 21 is a support surface 211, which is used to support the support plate 2 of the adjacent blister tray. The connecting position of the annular horizontal plate 4 and the outer annular vertical plate 5 is partially recessed into the inner cavity, thereby forming a support block 52 in the inner cavity. The bottom surface of the support block 52 is pressed against the annular horizontal plate 4 of the adjacent blister tray. In this way, during transportation, two adjacent blister trays can be stacked (the upper blister tray, its support plate 2 is pressed on the positioning column 21 of the lower blister tray, and its support block 52 is pressed on the annular horizontal plate 4 of the lower blister tray), which can improve the transportation efficiency. Third, since the blister tray obtained by the blister process is thin and the length of the blister tray is long, the rigidity of the blister tray is insufficient, especially the middle position of the support plate 2. Therefore, the column is not only used to position and fix the integrated busbar, but also can be used to support the support plate 2 of the upper blister tray to prevent the support plate 2 from sinking downward and damaging the electronic components on the integrated busbar. Furthermore, the height of the positioning column 21 is greater than the thickness of the integrated busbar, which can further prevent the support plate 2 from damaging the electronic components on the integrated busbar. Since the bracket and FPC of the integrated busbar have a certain degree of deformation ability, the present invention makes full use of this feature, and the thickness of the blister tray can be set to be relatively thin, and it is not necessary to set it thicker like the existing tray to ensure its rigidity. In this way, the number of trays loaded is large under the same handling volume, and the handling efficiency is high.

[0040] The shape of the outer annular vertical plate 5 is a trumpet shape that gradually becomes larger from top to bottom, and the bottom of the outer annular vertical plate 5 is lower than the bottom of the support block 52, so that multiple blister trays can be stacked on each other.

[0041] In this embodiment, the end of the support plate 2 is provided with a conductive row avoidance groove 22, which can accommodate the conductive row of the integrated busbar to avoid interference between the conductive row and the support plate 2, resulting in the arching of the two ends of the integrated busbar. The depth of the conductive row avoidance groove 22 is greater than the thickness of the support plate 2, so that a protruding first pressing block 23 is formed at the bottom of the support plate 2. The bottom of the first pressing block 23 is used to press and cooperate with the integrated busbar bracket on the lower blister tray. In this way, during transportation, the blister tray located above can unload force through the support block 52 and the positioning column 21 below, and can also unload force through the first pressing block 23, which increases the force area of ​​the tray and improves the structural reliability and service life of the support structure. The bottom of the first pressing block 23 cooperates with the integrated busbar bracket instead of the support plate 2, which can make the blister tray structure more compact. The first pressing block 23 presses against the integrated busbar bracket, which can fix the two ends of the integrated busbar, so that the integrated busbar is difficult to move during transportation, further avoiding the problem that the integrated busbar cannot be effectively fixed during transportation and the electronic components are easily damaged.

[0042] In practice, the blister tray located above is in direct contact with the integrated busbar. If the pressure is too great, the integrated busbar bracket is easily damaged. Therefore, in this embodiment, the depth of the conductive row avoidance groove 22 is less than the height of the inner annular vertical plate 3. In this way, when the number of blister trays stacked is small, the support plate 2 does not sink to a large extent. At this time, the first pressure block 23 does not contact the integrated busbar bracket below. The two adjacent blister trays are only supported by the positioning column 21 and the support block 52. The first pressure block 23 will not cause damage to the integrated busbar bracket row. When the number of blister trays is large, the support plate 2 sinks to a relatively large extent. At this time, the first pressure block 23 contacts the integrated busbar bracket below. The blister tray located below has a larger force-bearing area, which can improve the structural reliability and service life of the support structure. Furthermore, since there is a gap between the first pressure block 23 and the integrated busbar bracket below at the beginning, the blister tray located above mainly unloads the force through the positioning column 21 and the support block 52, and the first pressure block 23 assists in unloading the force. In this way, the first pressure block 23 will not exert a large force on the integrated busbar bracket below, thereby reducing the impact on the integrated busbar bracket.

[0043] Among them, preferably, the difference between the depth of the conductive bar avoidance groove 22 and the height of the inner annular vertical plate 3 is 1mm to 3mm. In this way, when the number of blister trays stacked is small, it will not contact the integrated busbar below to protect the integrated busbar. When the number of blister trays is large, it can also assist in unloading force, thereby improving the structural reliability and service life of the supporting structure. At the same time, it will not exert a large force on the integrated busbar bracket below, reducing the impact on the integrated busbar bracket.

[0044] In this embodiment, the conductive row avoidance groove 22 is arranged opposite to the first groove 51, so that when manually moving the blister tray, fingers can be inserted into the conductive row avoidance groove 22 and the first groove 51, so as to grasp the periphery of the blister tray, which is convenient for grasping and carrying. Since the conductive row avoidance groove 22 is a groove sunken downward on the support plate 2 and has a certain depth, there is enough space for fingers to grasp when carrying, and grasping is more convenient.

[0045] Furthermore, the position of the first groove 51 on the outer annular vertical plate 5 is recessed inward to form a hand-holding groove 53, which is more convenient for manual grasping.

[0046] Since the conductive row avoidance grooves 22 are only arranged at one end of the support plate 2 and the number is relatively small, in the present embodiment, the support plate 2 is further provided with downwardly protruding second pressing blocks 24 at both ends in the length direction thereof, and the bottom of the second pressing block 24 is flush with the bottom of the first pressing block 23, so that the second protrusion can also provide auxiliary support and unload force, thereby improving the stability and reliability of the blister tray during stacking, and can increase the service life of the main supporting structure.

[0047] In this embodiment, since the first groove 51 and the support block 52 are two corresponding structures at the same position, and the positioning column 21 is an upwardly arched hollow column, if the two trays are directly stacked, the support block 52 of the upper tray will be stuck in the first groove 51 of the lower tray, and the positioning column 21 at the upper position will be sleeved on the positioning column 21 of the lower tray, so that there is no gap between the two trays to avoid interference with the integrated busbar. For this reason, in this embodiment, the spacing between two adjacent first grooves 51 is configured to be unequal, so that the first grooves 51 and the support blocks 52 of two adjacent blister trays are staggered, and the spacing between two adjacent positioning columns 21 is unequal, so that the top surfaces of the positioning columns 21 of the two adjacent blister trays and the bottom surfaces of the positioning columns 21 are staggered.

[0048] In this embodiment, a plurality of spring-piece avoiding grooves 25 are provided on the support plate 2, and the plurality of spring-piece avoiding grooves 25 are arranged at intervals along the length direction of the support plate 2, so as to avoid spring pieces on the bracket and avoid interference.

[0049] Since the edge of each mounting slot 111 of the bracket is provided with a spring sheet, the spring sheet avoidance slot 25 on the support plate 2 is also provided accordingly, which requires the bracket to be provided with a large number of spring sheet avoidance slots 25. On the basis of ensuring that the thickness of the blister tray is not thick and the tray can have a large number of loads under the same handling volume, if more spring sheet avoidance slots 25 are provided, the material at the position where the spring sheet avoidance slots 25 are provided is insufficient, and the thickness after molding is relatively thin and the strength is insufficient. At the same time, after the blister trays are stacked, the middle position of the product on the blister tray on the lower layer cannot be fixed, and the product is prone to jumping during the handling process, causing damage. Therefore, in order to avoid insufficient local strength and the inability to fix the middle position of the product on the pallet and cause damage due to the provision of more spring clip air-avoiding grooves 25, at least some of the spring clip air-avoiding grooves 25 are connected to form a second groove 26, and the depth of the second groove 26 is greater than the thickness of the support plate 2, thereby forming a protruding third pressing block 27 at the bottom of the support plate 2. In this way, compared with directly forming a corresponding number of spring clip air-avoiding grooves 25, less material is required to connect at least some of the spring clip air-avoiding grooves 25, which ensures the strength of this position. At the same time, since less material is required to form the air-avoiding grooves, the second groove 26 can be formed to a deeper depth, so that the bottom surface of the third pressing block 27 is used to press-fit with the integrated busbar aluminum bar on the adjacent blister tray, thereby finally fixing the middle position of the product.

[0050] Since the sizes of the spring clips and the spring clip avoidance grooves 25 are relatively small, the above-mentioned connection of multiple spring clip avoidance grooves 25 can reduce the adverse effects caused by manufacturing errors and assembly errors. In addition, multiple spring clip avoidance grooves 25 are connected, and the groove size becomes larger. Compared with forming multiple independent spring clip avoidance grooves 25, the manufacturing difficulty is lower, and the problem of insufficient strength after forming due to insufficient material when forming multiple continuous spring clip avoidance grooves 25 is avoided.

[0051] In this embodiment, a component avoidance groove 28 is provided on the support plate 2, which can avoid electronic components and avoid damage to the components.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
