[0048] The battery production test equipment technical field is an important part of the battery industry, which covers the entire production process of the battery from raw material processing to finished battery assembly. In this process, there are many key process links such as capacity distribution and formation, among which the formation and capacity distribution process is a key link in the battery production process. The formation process aims to activate the chemical active substances of the positive and negative electrodes of the battery to ensure that the battery has stable electrochemical reaction capability, and the capacity distribution process classifies the activated battery capacity to meet the needs of different application scenarios.

[0049] In the prior art, the probe assembly is arranged on the sliding bracket, and the sliding bracket is slidably connected with the mounting bracket of the formation and capacity distribution equipment, so that the probe assembly can slide relative to the mounting bracket, thereby facilitating the maintenance of the probe assembly. The sliding bracket not only needs to be adapted to the size and shape of the probe assembly, but also needs to have a certain bearing capacity. The existing sliding bracket for arranging the probe assembly is a welded frame formed by welding a plurality of metal pieces.

[0050] However, the welding process has a high cost, and the welded part is prone to breakage, which not only increases the cost of the entire formation and capacity distribution equipment, but also is prone to breakage when the welded frame has a high bearing capacity, causing the probe assembly to fall and be damaged.

[0051] Based on this, the embodiment of the present application discloses a pull-out support, which can be detachably connected by a first sliding piece, a second sliding piece and a connecting piece to form an installation frame body, and no longer needs a relatively complex and expensive welding process, has the advantages of simple assembly and reliable structure, can reduce production and manufacturing cost, and improve production efficiency.

[0052] The technical solutions of the present application will be further described below in combination with embodiments and drawings.

[0053] Please refer to Figure 1 , Figure 1 The structure diagram of the pull-out support disclosed by the embodiment of the present application is shown. The embodiment of the present application discloses a pull-out support applied to a battery production and testing device, the battery production and testing device comprising an installation support 30 and a probe assembly 22, the probe assembly being used for testing a battery to be tested, the pull-out support comprising a first sliding piece 11, a second sliding piece 12, an installation piece 13 and a connecting piece 14, the first sliding piece 11 and the second sliding piece 12 both extending along a first horizontal direction a and oppositely arranged along a second horizontal direction b, the connecting piece 14 being detachably connected between the first sliding piece 11 and the second sliding piece 12, the installation piece 13 being connected between the first sliding piece 11 and the second sliding piece 12, the first sliding piece 11 and the second sliding piece 12 being respectively used for slidingly connecting with the installation support 30 along the first horizontal direction a; wherein the first horizontal direction a is perpendicular to the second horizontal direction b; wherein the connecting piece 14 is used for slidingly connecting the probe assembly 22 along the second horizontal direction b, so that the position of the probe assembly 22 along the second horizontal direction a can be adjusted to adapt to the battery to be tested with different electrode spacings.

[0054] In some embodiments, the battery can comprise one or more battery cells, the probe assembly can test the battery cells of the battery to be tested, the battery to be tested can be a power battery or an energy storage battery pack, and the battery to be tested can be used as a power source of a new energy vehicle such as a plug-in hybrid drive, a pure electric drive and a fuel cell drive.

[0055] Specifically, the battery production test equipment plays a key role in the production of lithium batteries. It not only activates the chemical properties of the battery, but also ensures the consistency and performance of the battery through precise testing and sorting. The battery production test equipment includes formation and capacity equipment, DCIR (Direct Current Internal Resistance) equipment, and OCV (Open Circuit Voltage) equipment, etc. The battery production test equipment can include a mounting bracket 30 and a probe assembly 22. The mounting bracket 30 is the entire frame of the battery production test equipment, and the probe assembly 22 can include multiple probes. The probes are placed on the electrodes of the battery to be tested, provide power to the battery to be tested, and collect various data of the battery to be tested to test the battery to be tested. The probe assembly 22 is connected to the connecting piece 14, and the connecting piece 14 can slide along the first horizontal direction a with respect to the mounting bracket 30 and the first sliding piece 11 and the second sliding piece 12. The user can pull out the probe assembly 22, which is convenient for installing, debugging, maintaining and replacing the probe assembly 22, etc., thereby improving the maintenance efficiency and convenience of the equipment. The probe assembly 22 and the connecting piece 14 are slidably connected along the second horizontal direction b, and can slide along the connecting piece 14, which is convenient for adjusting the position of the probe assembly 22 along the second horizontal direction b, so that the probe assembly 22 has better applicability and can adapt to different probe positions.

[0056] In combination Figure 1 In some embodiments, the pull-out bracket includes a first sliding piece 11 and a second sliding piece 12. The first sliding piece 11 and the second sliding piece 12 can be a strip structure or a plate body. When the first sliding piece 11 and the second sliding piece 12 are a plate body, they can be a profile, a plastic plate, a sheet metal part, etc. When the first sliding piece 11 and the second sliding piece 12 are a sheet metal part, the weight of the first sliding piece 11 and the second sliding piece 12 can be reduced, and the production cost of the pull-out bracket can be reduced, which is conducive to lightweight and low-cost design.

[0057] In some embodiments, the first sliding piece 11 and the second sliding piece 12 extend along the first horizontal direction a and are oppositely arranged along the second horizontal direction b. The first sliding piece 11 and the second sliding piece 12 are respectively used for sliding connection with the mounting bracket 30 along the first horizontal direction a, so that the pull-out bracket can slide with respect to the mounting bracket. The pull-out bracket can be at least partially pulled out of the mounting bracket or pulled into the mounting bracket, so as to facilitate the maintenance of the probe assembly 22 and other components provided on the pull-out bracket by the operator.

[0058] In combination Figure 1In some embodiments, the mounting member 13 can be a polygonal connecting block or a plate body. The mounting member 13 can be an entire plate or a plurality of plates. When the mounting member 13 is a plurality of plates, the mounting member 13 can be a first mounting plate 131 and a second mounting plate 132. The first mounting plate 131 can be connected to the first sliding member 11, and the second mounting plate 132 can be connected to the second sliding member 12. The connection can be achieved by bolt connection, clamping, gluing, or the like. Alternatively, the first mounting plate 131 and the first sliding member 11 can be integrally formed by bending sheet metal, and the second mounting plate 132 and the first sliding member 11 can be integrally formed by bending sheet metal. This manufacturing method is not only simple and fast, but also can simplify the connection and installation steps, save costs, and improve the connection strength.

[0059] In combination Figure 1 In some embodiments, the connecting member 14 can be a polygonal body or a plate body. The connecting member 14 can be connected between the first sliding member 11 and the second sliding member 12 or can be detachably connected to the bottom of the first sliding member 11 and the second sliding member 12. The connecting member 14 can be one or a plurality of members. When the number of connecting members 14 is two, the two connecting members 14 can be arranged at the two ends of the first sliding member 11 and the second sliding member 12 along the first horizontal direction a. The two connecting members 14 can connect the first sliding member 11 and the second sliding member 12 to form a rectangular frame, which can have a stable support structure and can effectively resist external forces such as vibration and impact during equipment operation, thereby ensuring normal operation of the equipment.

[0060] In combination Figure 1 In some embodiments, the connecting member 14 can be detachably connected to the first sliding member 11 and the second sliding member 12. The detachable connection can be achieved by clamping, bolt connection, gluing, or the like. When the connection is achieved by bolt connection, the connection structure is simple, easy to process, and conducive to reducing production costs. The bolt connection can also have a certain strength to ensure the fastening of the connection between the connecting member 14 and the first sliding member 11 and the second sliding member 12. Compared with the welding method, the detachable connection no longer requires a relatively complex and expensive welding process. Welding assembly requires welding equipment such as a welding machine, welding wire, and welding rod. The purchase and maintenance costs of these devices are high, and professional operators are required for operation and maintenance. If a finished welding frame is purchased directly, a higher purchase cost is required. Moreover, the detachable connection can avoid the problem of connection rupture due to corrosion and fatigue of the welding site after welding connection, which can separate the connecting member 14 from the first sliding member 11 and the second sliding member 12, cause the probe assembly 22 to fall off, and damage the probe assembly 22. The detachable connection can improve the reliability of the connection structure.

[0061] In combination Figure 1 And Figure 7 ,Figure 7 Another structural schematic view of part of the battery production test device disclosed in the embodiments of the present application is shown. In some embodiments, the mounting member 13 is connected between the first sliding member 11 and the second sliding member 12. The mounting member 13 can be arranged in the internal space formed by the first sliding member 11 and the second sliding member 12, connected to the first sliding member 11 and the second sliding member 12 respectively, or arranged between the surfaces where the side walls of the first sliding member 11 and the second sliding member 12 face away from each other, i.e., the mounting member 13 can be arranged above the first sliding member 11 and the second sliding member 12, connected to the top of the first sliding member 11 and the top of the second sliding member 12 respectively, but not protruding from the side walls of the first sliding member 11 and the second sliding member 12 facing away from each other. By arranging the mounting member 13 between the first sliding member 11 and the second sliding member 12, the space on the side where the first sliding member 11 and the second sliding member 12 face away from each other can be avoided by the mounting member 13, and the space utilization can be improved. As shown in FIG. 1B, when the first sliding member 11 and the second sliding member 12 are arranged on the mounting bracket 30, the first guide member 40 corresponding to the first sliding member 11 and the second guide member 50 corresponding to the second sliding member 12 can be arranged, and the first guide member 40 and the second guide member 50 are arranged opposite to each other along the second horizontal direction b. The first sliding member 11 can be slidably connected to the first guide member 40 through the cooperation of the sliding block 111 and the sliding groove 60, and the second sliding member 12 can be slidably connected to the second guide member 50 through the cooperation of the sliding block 111 and the sliding groove 60. The first sliding member 11 and the second sliding member 12 are located between the first guide member 40 and the second guide member 50. On the premise that the width between the first guide member 40 and the second guide member 50 is constant, the first sliding member 11 can be closer to the first guide member 40, and no space for arranging the mounting member 13 is needed between the first guide member 40 and the first sliding member 11. The second sliding member 12 can be closer to the second guide member 50, and no space for arranging the mounting member 13 is needed between the second guide member 50 and the second sliding member 12. The distance between the first sliding member 11 and the second sliding member 12 can be larger, the length of the connecting member 14 can be longer, the probe assembly 22 sliding along the connecting member 14 can have a larger sliding stroke, and the probe assembly 22 can be more flexible and adapt to more models of electrode positions of the battery to be tested. Figure 7

[0062] ​According to the embodiment of the utility model, the pull-out support is provided with a first sliding part 11, a second sliding part 12, a mounting part 13 and a connecting part 14, the first sliding part 11 and the second sliding part 12 are oppositely arranged along a second horizontal direction b, and the two are stably connected through the detachable connecting part 14, thereby jointly forming the main frame structure of the pull-out support. This frame structure design discards the traditional welding process, and through the detachable connecting mode of the connecting part 14, such as bolt connection, not only the assembly process is simplified, the dependence on professional welding equipment and operators is reduced, the production cost is effectively controlled, but also the subsequent maintenance, replacement and component upgrading are facilitated. Moreover, the mounting part 13 is connected between the first sliding part 11 and the second sliding part 12, does not occupy the space opposite to each other of the first sliding part 11 and the second sliding part 12, makes the overall layout of the pull-out structure more reasonable, can effectively utilize the space, and improves the space utilization rate.

[0063] In combination Figure 1 In some embodiments, the mounting part 13 comprises a first mounting plate 131 and a second mounting plate 132, the first mounting plate 131 and the second mounting plate 132 are spaced apart along the second horizontal direction b, the first mounting plate 131 is connected with the first sliding part 11, and the second mounting plate 132 is connected with the second sliding part 12.

[0064] Specifically, the mounting member 13 can be an entire plate body connected between the first sliding member 11 and the second sliding member 12, or can be divided into a first mounting plate 131 and a second mounting plate 132, which are spaced apart along the second horizontal direction b, so that a stable support structure is formed between the first sliding member 11 and the second sliding member 12, and space is reserved for other components or cable arrangement inside the pull-out bracket. The connection mode of the first mounting plate 131 and the first sliding member 11, and the connection mode of the second mounting plate 132 and the second sliding member 12, can be selected according to actual production needs and structural strength requirements. For example, when the connection strength is required to be high and the assembly steps need to be simplified, an integrated molding method can be used, such as the first mounting plate 131 and the first sliding member 11 being integrally formed by sheet metal bending process, which not only ensures the connection strength between the two, but also reduces the number of parts and assembly processes, and improves production efficiency. If the convenience of subsequent maintenance or replacement is considered, or the first mounting plate 131 and the first sliding member 11 are made of different materials, a detachable connection mode such as bolt connection or clamping can be selected. The bolt connection has the characteristics of reliable connection and easy disassembly, and by predefining corresponding screw holes on the first mounting plate 131 and the first sliding member 11, a stable connection can be achieved using bolts and nuts; the clamping can be achieved by setting a buckle on the first mounting plate 131 and a corresponding clamping groove on the first sliding member 11, or vice versa, through the cooperation of the buckle and the clamping groove to achieve quick assembly and disassembly. This method can significantly improve the assembly speed in scenarios where the connection strength is not extremely high.

[0065] In combination Figure 1 In some embodiments, the first sliding member 11 is integrally formed with the first mounting plate 131; and / or, the second sliding member 12 is integrally formed with the second mounting plate 132.

[0066] Specifically, the first sliding member 11 can be integrally formed with the first mounting plate 131, or the second sliding member 12 can be integrally formed with the second mounting plate 132, or the first sliding member 11 can be integrally formed with the first mounting plate 131 and the second sliding member 12 can be integrally formed with the second mounting plate 132. The first sliding member 11 and the first mounting plate 131, and the second sliding member 12 and the second mounting plate 132 can be either spliced or integrally formed. When integrally formed, it can be achieved by casting, bending, etc. Among them, through the sheet metal bending process, the first sliding member 11 and the first mounting plate 131 are formed by bending from the same sheet metal plate, and the second sliding member 12 and the second mounting plate 132 are the same. This integrated structure design can effectively improve the structural strength of the connection part, avoid the risk of looseness that may exist in separate connection, reduce the number of parts and assembly processes, and reduce the error accumulation in the production process, further improving the overall structural precision and stability of the pull-out bracket.

[0067] In combination Figure 1 In some embodiments, the first sliding member 11 is a sheet metal member, and the top of the first sliding member 11 is bent to form the first mounting plate 131; and / or the second sliding member 12 is a sheet metal member, and the top of the second sliding member 12 is bent to form the second mounting plate 132.

[0068] Specifically, the first sliding member 11 is a sheet metal member, and the top of the first sliding member 11 is bent to form the first mounting plate 131, or the second sliding member 12 is a sheet metal member, and the top of the second sliding member 12 is bent to form the second mounting plate 132, or the first sliding member 11 is a sheet metal member, and the top of the first sliding member 11 is bent to form the first mounting plate 131, and the second sliding member 12 is a sheet metal member, and the top of the second sliding member 12 is bent to form the second mounting plate 132. Using sheet metal members to manufacture the first sliding member 11 and the second sliding member 12 can make full use of the characteristics of sheet metal materials, effectively control the overall weight while ensuring the structural strength, and achieve the lightweight design of the pull-out support. By bending the top of the first sliding member 11 to form the first mounting plate 131 and bending the top of the second sliding member 12 to form the second mounting plate 132, this processing method has significant advantages. First, the bending process is mature and reliable, easy to realize automated production, and can effectively improve production efficiency and reduce the processing cost of single product. Second, the integral bending forming makes the first mounting plate 131 and the first sliding member 11, the second mounting plate 132 and the second sliding member 12 have no connection joints, thereby greatly enhancing the structural strength and rigidity of the connection part, avoiding the stress concentration or connection loosening problem that may be caused by welding or bolt connection, and ensuring the stability and reliability of the mounting member 13 during the operation of the probe assembly 22 and the equipment. In addition, this integrated structure also reduces the number of parts, simplifies the assembly process, reduces the possibility of errors in the assembly process, and further improves the overall precision of the pull-out support. Moreover, the sheet metal member is light in weight and high in strength, which can meet the strength requirements of the pull-out support while reducing the weight of the pull-out support, which is helpful for lightweight design.

[0069] In combination Figure 1 In some embodiments, the pull-out support further comprises a reinforcing member 15 connected with the first sliding member 11 and the second sliding member 12, respectively.

[0070] Specifically, no other structure can be arranged between the first sliding member 11 and the second sliding member 12, or a reinforcing member 15 can be arranged. The arrangement of the reinforcing member 15 can further improve the structural rigidity and stability of the whole pull-out support, especially in the case that the device may be subjected to vibration or impact during operation, effectively preventing the relative deformation or displacement between the first sliding member 11 and the second sliding member 12, thereby ensuring the positional accuracy of the probe assembly 22 and the accuracy of the test. The structural form of the reinforcing member 15 can be designed according to actual needs, for example, it can be a bar, a plate structure or other shapes that can enhance the connection strength. The reinforcing member 15 can be connected at the middle, end or other key stress position of the first sliding member 11 and the second sliding member 12. Its connection mode can also adopt detachable connection modes such as bolt connection and clamping, so as to facilitate installation, maintenance and replacement. For example, when the first sliding member 11 and the second sliding member 12 are connected at both ends by two connecting members 14 to form a rectangular frame, the reinforcing member 15 is additionally arranged at the middle position of the frame, which can effectively resist the bending deformation of the frame when subjected to stress, and significantly improve the carrying capacity of the whole pull-out support.

[0071] In combination Figure 1 In some embodiments, at least one reinforcing member 15 is arranged close to the bottom of the first sliding member 11 and close to the center of the first sliding member 11 along the second horizontal direction b.

[0072] Specifically, the number of reinforcing members 15 can be multiple, which can be arranged at multiple positions between the first sliding member 11 and the second sliding member 12. At least one reinforcing member 15 is arranged close to the bottom of the first sliding member 11 and close to the center of the first sliding member 11 along the second horizontal direction b. The reinforcing member 15 at this position can provide support from the center area of the bottom of the first sliding member 11 and the second sliding member 12, effectively enhancing the bending resistance of the pull-out support in the vertical direction c. Moreover, when the probe assembly 22 is pressed and contacts the battery to be tested, the center position of the probe assembly 22 along the second horizontal direction b lacks fixation, and the probe assembly 22 has a certain length in the second horizontal direction b. The middle position is easily bulged upwards after being subjected to stress, and the reinforcing member 15 at this position can prevent the middle position of the probe assembly 22 from being deformed upwards, avoid damaging the probe assembly 22, and improve the service life of the probe assembly 22.

[0073] In combination Figure 1 In some embodiments, at least one reinforcing member 15 is arranged close to one end of the first sliding member 11 along the first horizontal direction a, and the reinforcing member 15 is configured to be held by a hand.

[0074] Specifically, the number of the reinforcing member 15 can be multiple, which can be arranged at multiple positions between the first sliding member 11 and the second sliding member 12. At least one reinforcing member 15 is arranged at an end of the first sliding member 11 along the first horizontal direction a, which is specially configured as a structure for holding by hand in addition to the role of enhancing the connection strength between the first sliding member 11 and the second sliding member 12. Such a design fully considers the actual needs of the operator during the pulling of the bracket, when it is necessary to pull out or push in the pulling bracket from the mounting bracket 30, the operator can directly hold the reinforcing member 15, without the need to find the force point additionally, so that the pulling operation is more convenient and labor-saving. The reinforcing member 15 can be a rod-shaped structure, which is convenient for holding by hand and avoids scratching the hands of the operator caused by sharp edges and corners; and anti-slip lines can be added on the reinforcing member 15 to improve the friction between the hands and the reinforcing member 15, prevent slipping during the pulling process, and further improve the safety and stability of the operation. At the same time, the holding function is integrated on the reinforcing member 15, without the need to additionally increase a special handle part, which simplifies the overall structure of the pulling bracket, reduces the production cost, and also makes the appearance of the pulling bracket more simple and unified. In addition, in the battery production test equipment, the first end along the first horizontal direction a is a feeding end, and the other end along the first horizontal direction a is a maintenance end, which are arranged separately, so as to avoid the influence of the trolley and other components of the feeding end on the maintenance work of the maintenance personnel, and the reinforcing member 15 in the embodiment of the application is arranged at an end of the first sliding member 11 along the first horizontal direction a, which can be at the maintenance end, so as to facilitate the maintenance personnel to pull the bracket.

[0075] In combination Figure 2 , Figure 2 The structure schematic diagram of the pulling test assembly disclosed in the embodiment of the application is shown. The embodiment of the application also discloses a pulling test assembly, which comprises a probe assembly 22 and the foregoing pulling bracket; wherein the probe assembly 22 is slidably connected to the connecting member 14 along the second horizontal direction b.

[0076] In combination Figure 2 In some embodiments, the pulling test assembly further comprises a power supply module 21, the power supply module 21 is electrically connected with the probe assembly 22, and the power supply module 21 is fixedly connected to the mounting member 13.

[0077] Specifically, the battery production test equipment can include an ACDC (Alternating Current to Direct Current) power module 21 and a DCDC (Direct Current to Direct Current) power module 21, the ACDC power module 21 is capable of converting alternating current into high-voltage direct current, and the DCDC power module 21 is capable of converting high-voltage direct current into low-voltage direct current. The power module 21 in the embodiment of the application can be a DCDC power module 21, which can be arranged on the mounting bracket 30 or fixedly connected to the mounting member 13. In the embodiment of the application, the power module 21 is fixedly connected to the first mounting plate 131 and / or the second mounting plate 132, and can be fixed by means of bolt connection. This fixing mode ensures the stability of the power module 21 during movement of the pull-out bracket, avoids loosening of electrical connection or damage to the module due to shaking, and shortens the distance between the DCDC power module 21 and the probe assembly 22 by arranging them on the same pull-out structure, thereby simplifying the line connection. The probe assembly 22, as a component directly contacting the electrodes of the battery to be tested, is slidably connected to the connecting member 14 along the second horizontal direction b, for example, by cooperating with the slide rail arranged on the connecting member 14 through the slide block 111. This sliding connection design enables the probe assembly 22 to be flexibly adjusted according to the electrode spacing of different models of batteries to be tested. By sliding the probe assembly 22 to the appropriate position on the connecting member 14 and fixing it, the test requirements of batteries of various specifications can be met, greatly enhancing the universality and application range of the pull-out test assembly. When the battery to be tested is conveyed to the test position, the pull-out bracket drives the probe assembly 22 to move to the test station, and then the pull-out test assembly moves downward, so that the probe assembly 22 contacts the electrodes of the battery. The power module 21 supplies power to the probe assembly 22 through the wire, thereby completing the electrical performance test of the battery. After the test is completed, the probe assembly 22 is reset.

[0078] In some embodiments, the pull-out test assembly further includes a protective member (not shown in the figure), which is fixedly connected to the mounting member 13 and has a protective plate perpendicular to the second horizontal direction b, the protective plate being used to protect the wire harness for electrical connection between the power module 21 and the probe assembly 22.

[0079] Specifically, the wire harness electrically connected between the power module 21 and the probe assembly 22 can also be protected by a protection piece. The protection piece can be an "L"-shaped plate, the bottom of which is fixedly connected to the mounting piece 13, for example, by bolt connection or clamping. The protection plate is perpendicular to the first horizontal direction a and can shield the wire harness from the side or end, thereby protecting the wire harness. The protection piece can be adjusted according to the specific direction and arrangement position of the wire harness. For example, when the wire harness extends from the power module 21 to the probe assembly 22 along the first horizontal direction a, the protection plate can be arranged outside the wire harness along the vertical direction c to prevent external objects from directly contacting the wire harness. The height of the protection plate can be higher than the surrounding components (such as the top block) along the pulling path of the pull bracket, so as to avoid friction between the surrounding components and the wire harness during movement of the pull bracket. The fixed connection between the protection piece and the mounting piece 13 ensures the stability of the position of the protection piece during movement of the pull bracket and prevents the protection piece from being displaced or falling off due to vibration. In addition, the protection piece can be made of an insulating material, such as plastic or rubber, to further improve electrical safety and prevent the risk of electric shock when the wire harness is accidentally damaged. Furthermore, the protection piece can be designed to be detachable to facilitate installation, maintenance, and replacement of the wire harness. When maintenance of the wire harness is required, the protection piece can be detached from the mounting piece 13 for operation, without the need to disassemble the overall structure of the pull bracket, thereby improving the convenience of maintenance.

[0080] In combination Figure 2 and Figure 3 , Figure 2 is a structural schematic view of a pull test assembly disclosed in an embodiment of the present application, Figure 3 is a structural schematic view of part of a pull test assembly disclosed in an embodiment of the present application, which is provided with four power modules 21. In some embodiments, the mounting piece 13 has a mounting portion 133 perpendicular to the vertical direction c, and the upper surface of the mounting portion 133 is provided with a mounting surface for connecting to the bottom of the power module 21.

[0081] Specifically, the mounting member 13 can be connected with the power module 21 in a horizontal direction or in a vertical direction c. The mounting member 13 in the embodiments has a mounting portion 133 perpendicular to the vertical direction c. When the mounting member 13 is a plate body, the upper surface of the mounting portion 133 is a mounting surface. When the mounting member 13 includes a first mounting plate 131 and a second mounting plate 132, the mounting portion 133 can be the upper surfaces of the first mounting plate 131 and the second mounting plate 132. That is, when the mounting member 13 includes the first mounting plate 131 and the second mounting plate 132, the upper surface of the first mounting plate 131 and the upper surface of the second mounting plate 132 jointly constitute the mounting portion 133, and the two upper surfaces are located in the same plane. Such a design is to ensure that the bottom of the power module 21 can be stably placed and connected to the mounting member 13, so that the mounting member 13 can install the power module 21 while also serving as a load-bearing part. Since the power module 21 is usually a regular cuboid or rectangular cuboid structure, its bottom needs a flat and continuous support surface to ensure stability after installation. The two upper surfaces of the first mounting plate 131 and the second mounting plate 132 located in the same plane can provide stable support for the power module 21. If the upper surfaces of the first mounting plate 131 and the second mounting plate 132 are not in the same plane, it will cause uneven stress on the bottom of the power module 21, which may result in instability of the power module 21, and further affect the reliability of electrical connection and the safety of equipment operation.

[0082] In combination Figure 2 and Figure 4 , Figure 4 Another part of the structure of the pull-out test assembly provided with four power modules 21 is shown in the structural schematic view. In some embodiments, the mounting member 13 also has a protection portion 134 perpendicular to the second horizontal direction b, which is used to protect the wire harness for electrical connection between the power module 21 and the probe assembly 22.

[0083] Specifically, a wire harness can be arranged between the power module 21 and the probe assembly 22 for electrical connection, so that the power module 21 can supply power to the probe assembly 22. The wire harness after being led out of the power module 21 can be exposed or can be protected by the protection part 134. The protection part 134 can be a plate-shaped structure extending in the vertical direction c from the edge of the mounting part 13. For example, when the mounting part 13 includes the first mounting plate 131 and the second mounting plate 132, the protection part 134 can be bent upward from the first mounting plate 131 and the second mounting plate 132, that is, the protection part 134 is integrally formed with the mounting part 133, and does not need to be additionally assembled, which is beneficial to improve the production efficiency. The protection part 134 can surround the wire harness electrically connected between the power module 21 and the probe assembly 22 to form a physical barrier, effectively preventing the wire harness from being accidentally hooked, rubbed or pressed with other parts inside the device during the movement of the pull-out bracket, avoiding the damage of the insulation layer of the wire harness due to short circuit, leakage and other safety hazards, and also preventing external dust and impurities from directly adhering to the surface of the wire harness, affecting the heat dissipation and service life of the wire harness. The height of the protection part 134 can be designed according to the arrangement height of the wire harness to ensure that the main part of the wire harness can be completely covered or surrounded.

[0084] In some embodiments, the pull-out test assembly further includes a support part (not shown in the figure) supported between the mounting part 13 and the probe assembly 22 in the vertical direction c.

[0085] Specifically, the two ends of the probe assembly 22 are respectively connected to the two connecting parts 14 in a sliding manner, and the two ends can be supported by the connecting parts 14. The pull-out test assembly can not be provided with an additional support part, or can be provided with a support part supported between the mounting part 13 and the probe assembly 22. The support part can be connected to the probe assembly 22 or the mounting part 13. When the support part is connected to the mounting part 13, it is connected in a sliding manner along the second horizontal direction b, which can adapt to the position change of the probe assembly 22 along the second horizontal direction b. The support part can be a columnar or plate-shaped structure arranged in the vertical direction c. When the probe assembly 22 is subjected to an upward pressure during testing, the support part can provide effective support force for the probe assembly 22, share the load borne by the probe assembly 22, and prevent the probe assembly 22 from being deformed upward due to the lack of support in the middle, thereby ensuring the flatness of the probe assembly 22 during testing and the accuracy of contact with the electrodes of the battery to be tested.

[0086] In some embodiments, the support part is arranged near the center of the first sliding part 11 or the second sliding part 12 along the first horizontal direction a.

[0087] Specifically, the number of the support members can be one or multiple, and the support members are arranged near the center of the first sliding member 11 or the second sliding member 12 along the first horizontal direction a. The support members are not necessarily connected to the first sliding member 11 and the second sliding member 12. Arranging the support members in this position can accurately support the middle region of the probe assembly 22, effectively resist the upward bending trend of the probe assembly 22 when it is in contact with the battery, further ensure the position accuracy and test stability of the probe assembly 22, and prolong the service life of the probe assembly 22.

[0088] In some embodiments, the number of the support members is multiple, and the multiple support members are uniformly distributed along the first horizontal direction a.

[0089] Specifically, when the number of the support members is one, the support member can be arranged at the center of the probe assembly 22. When the number of the support members is multiple, the support members can be concentrated in the center of the probe assembly 22 or uniformly distributed, for example, two, three or more support members are arranged at equal intervals along the first horizontal direction a, so that the probe assembly 22 can obtain effective vertical support at multiple positions in the length direction. This uniform distribution can more evenly distribute the load borne by the probe assembly 22 to the mounting member 13, avoid deformation of the probe assembly 22 or damage to the support members caused by excessive local stress, and further improve the overall stability and deformation resistance of the probe assembly 22 during the test process. This can ensure that the probe assembly 22 can maintain good flatness and position accuracy even in long-time and high-frequency test work, thereby ensuring the reliability and consistency of the battery test results.

[0090] In combination Figure 2 to Figure 4 In some embodiments, the pull-out bracket further comprises a terminal mounting rack 16 and a wire harness mounting rack 17. The terminal mounting rack 16 is arranged on the first sliding member 11, the second sliding member 12 or the mounting member 13, and is used to mount the wiring terminal. The wire harness mounting rack 17 is connected between the power supply module 21 and the terminal mounting rack 16, and is used to accommodate the wire harness.

[0091] Specifically, the power module 21 can be electrically connected to other components such as the control module, external power source, etc. not only through the wire harness, but also can be integrated into a terminal block, and then the terminal block is arranged on the terminal mounting rack 16 for connection. The terminal mounting rack 16 can adopt a plate or block structure, and is fixed to a suitable position of the first sliding member 11 or the second sliding member 12, for example, the side close to the power module 21, by means of bolts or buckles. The wire harness led out of the power module 21 and the wire harness leading to the probe assembly 22 can be connected in a centralized and reliable manner by arranging the terminal block on the terminal mounting rack 16, avoiding direct winding or random lapping of the wire harness, so that the connection of the wire is clearer and more orderly, and the later maintenance and maintenance are facilitated. The wire harness bracket 17 is connected between the power module 21 and the terminal mounting rack 16, which can be a U-shaped slot with an opening upward, forward or backward, a closed rectangular tube slot or other structure suitable for containing wire harness, and is installed on the mounting member 13 or the sliding member by means of buckles, adhesion or screws. The wire harness bracket 17 can neatly accommodate the wire harness between the power module 21 and the terminal mounting rack 16, effectively avoiding the wire harness from being exposed to the external environment and being damaged, and also preventing the wire harness from being scattered, entangled or unnecessarily rubbing with other components during the movement of the pull-out bracket, further improving the neatness of the wire layout and the safety of the overall structure. Through the cooperation of the terminal mounting rack 16 and the wire harness bracket 17, the orderly transition and protection of the wire harness from the power module 21 to the probe assembly 22 are realized, and the electrical system of the pull-out test assembly is more stable and reliable. The wire harness contained in the wire harness bracket 17 can be but is not limited to fan wire harness, temperature probe wire harness, test wire, dialing wire, etc.

[0092] In combination Figure 5 and Figure 7 , Figure 5 The structure diagram of part of the structure of the battery production test equipment disclosed in the embodiments of the present application is shown. The embodiments of the present application also disclose a battery production test equipment, which comprises a mounting bracket 30 and the foregoing pull-out test assembly; wherein the pull-out test assembly is slidingly connected to the mounting bracket 30.

[0093] In combination Figure 5 and Figure 7 In some embodiments, the battery production test equipment further comprises a first guide member 40 and a second guide member 50, the first guide member 40 and the second guide member 50 both extend along the first horizontal direction a and are oppositely arranged along the second horizontal direction b, the first guide member 40 and the second guide member 50 are both arranged on the mounting bracket 30, the first sliding member 11 is slidingly connected with the first guide member 40, and the second sliding member 12 is slidingly connected with the second guide member 50.

[0094] Specifically, the mounting bracket 30 serves as a basic frame of the battery production test equipment, and is used to carry the pull-out bracket, the probe assembly 22 and other related components. The first guide 40 and the second guide 50 can be linear guides, sliding rails or other structures with guiding functions. The first guide 40 and the second guide 50 can be made of profiles, and the first guide 40 and the second guide 50 made of profiles can have lower cost and lighter weight. The first guide 40 and the second guide 50 extend along the first horizontal direction a and are arranged opposite to each other in the second horizontal direction b, forming a pair of parallel guide tracks. The first sliding member 11 and the second sliding member 12 serve as the moving end of the pull-out bracket, and are respectively slidably connected with the first guide 40 and the second guide 50, for example, through the nested structure of the sliding block 111 and the guide rail. This design enables the pull-out bracket to stably reciprocate along the first guide 40 and the second guide 50, ensuring that the pull-out bracket does not deviate or shake during the pulling process, so that the probe assembly 22 can accurately enter and exit the test station. The probe assembly 22 is slidably connected to the connecting member 14 along the second horizontal direction b, so that when the pull-out bracket drives the probe assembly 22 to the test station, the probe assembly 22 can be fine-tuned on the connecting member 14 according to the specific model and electrode spacing of the battery to be tested, further improving the flexibility and adaptability of the test. When the battery is transported to the test position, the pull-out bracket is guided by the first guide 40 and the second guide 50 to stably send the probe assembly 22 into the test area along the first horizontal direction a. Then, the probe assembly 22 is adjusted to the position along the second horizontal direction b according to the battery specification, and then the contact test is performed. The whole process is coherent and accurate, effectively improving the automation level and test efficiency of battery production test.

[0095] In combination Figure 5 and Figure 6 In some embodiments, the top of the first guide 40 and / or the second guide 50 is provided with a force receiving member 70, the force receiving member 70 has an abutting surface 71 located between the first guide 40 and the second guide 50, and the first guide 40 and the second guide 50 are used to be fixedly connected with the mounting bracket 30. The pull-out bracket further comprises a plurality of top blocks 80, the plurality of top blocks 80 are respectively arranged on the top of the first sliding member 11 and the second sliding member 12, and / or the plurality of top blocks 80 are respectively arranged on the top of the connecting member 14. When the pull-out bracket is located in the first guide 40 and the second guide 50 at both ends along the first horizontal direction a, the top block 80 abuts against the abutting surface 71 of the force receiving member 70 along the vertical direction c.

[0096] Specifically, the battery production test equipment can not be provided with the matching structure of the force receiving member 70 and the top block 80, and the thickness of each structure of the pull-out support can be increased to improve the strength. The force receiving member 70 can be matched with the top block 80, and the force receiving member 70 can be a strip-shaped plate or a block-shaped structure that spans the top of the first guide member 40 and the second guide member 50 in the second horizontal direction b, and the abutting surface 71 is located between the first guide member 40 and the second guide member 50 and faces the pull-out support below. The first guide member 40 and the second guide member 50 are fixedly connected with the mounting support 30 by means of bolts or the like, and the force receiving member 70 is fixed on the top of the first guide member 40 and / or the second guide member 50, for example, by welding, bolt connection or one-piece forming. The top block 80 is correspondingly arranged on the top of the first sliding member 11, the second sliding member 12 or the connecting member 14 of the pull-out support, and the number thereof can be two, four or more according to the need of force balance, and generally one top block 80 is arranged at each of the four corners or the key load-bearing position of the pull-out support. The top of the top block 80 forms a contact surface matched with the abutting surface 71 of the force receiving member 70, and when the pull-out support moves to the range of the first guide member 40 and the second guide member 50 at both ends thereof, i.e., in the stable state of the test station or the non-test station, the contact surface of the top block 80 will abut against the abutting surface 71 of the force receiving member 70 in the vertical direction c. Through the abutment of the top block 80 and the force receiving member 70, most of the load in the vertical direction c can be transmitted to the first guide member 40 and the second guide member 50, and then transmitted to the mounting support 30 by the first guide member 40 and the second guide member 50, thereby effectively reducing the load-bearing burden of the sliding connection structure, preventing deformation due to long-term bearing of heavy load, affecting the pull-out movement, prolonging the service life of the sliding connection structure, and ensuring the smoothness of the movement of the pull-out support and the position accuracy. At the same time, the abutment of the top block 80 and the force receiving member 70 can also limit the pull-out support in the vertical direction c, prevent the pull-out support from jumping upward during movement due to vibration or other factors, and ensure the stability of the overall structure of the pull-out support. The material of the top block 80 can be a metal material with good wear resistance, such as steel or aluminum alloy.

[0097] In combination Figure 5 and Figure 6In some embodiments, a limiting piece can also be arranged on the first guide 40 and the second guide 50, and a limiting matching piece is arranged above the pull-out support, which will be clamped when the pull-out support slides to the outer limit position and the inner limit position in the pull-out direction, so as to avoid the pull-out support from being separated from the first guide 40 and the second guide 50. The limiting matching piece can be arranged above the first sliding piece 11 and the second sliding piece 12, and can also be arranged above the mounting piece 13, and can also be arranged on the top block 80. Arranging the top block 80 on the connecting piece 14 and arranging the limiting matching piece on the top block 80 can make the pull-out support have higher strength, and avoid the collision operation of the limiting piece and the limiting matching piece from deforming and damaging the pull-out support during the pull-out operation.

[0098] In combination Figure 5 And Figure 6 In some embodiments, a plurality of top blocks 80 are arranged above the sliding connection between the probe assembly 22 and the connecting piece 14, respectively.

[0099] Specifically, the top block 80 can be arranged at any position, or above the sliding connection between the probe assembly 22 and the connecting piece 14. The sliding connection between the probe assembly 22 and the connecting piece 14 is a key position for the probe assembly 22 to adjust the position in the second horizontal direction b, and is also a region with relatively concentrated stress. Arranging the top block 80 above the sliding connection can make the upward pressure on the probe assembly 22 during the test process directly transmitted to the top block 80 above it through the connecting piece 14, and then transmitted to the stress receiving piece 70 by the top block 80, and then dispersed to the first guide 40, the second guide 50 and the mounting support 30. This layout can realize the transmission and dispersion of force in place, avoid the stress concentration phenomenon caused by the transmission of pressure through other non-key structural components of the pull-out support, further enhance the structural stability and carrying capacity of the pull-out support under test conditions, ensure the contact pressure between the probe assembly 22 and the battery electrode stable, and improve the accuracy of test results.

[0100] In some embodiments, the pull-out test assembly further comprises a support piece supported between the mounting piece 13 and the probe assembly 22 in the vertical direction c; and at least part of the top blocks 80 are arranged on the top of the first sliding piece 11 and the second sliding piece 12 and above the support piece.

[0101] Specifically, the top block 80 can be arranged at any position, or above the support. The support supports the probe assembly 22 in the vertical direction c, and the top region of the support can correspondingly be provided with the top block 80. When the support is a plurality of columnar structures spaced apart in the second horizontal direction b, the top block 80 is arranged at the top of the first sliding member 11 and the second sliding member 12, and located directly above each support. In this way, the load of the probe assembly 22 transmitted to the mounting member 13 through the support can be further transmitted to the force receiving member 70 through the top block 80 directly above the support, forming a complete force transmission path from the probe assembly 22 to the support, then to the top block 80, the force receiving member 70, and finally to the mounting bracket 30. This design not only allows the support to directly support the probe assembly 22, but also allows the support to bear and disperse the pressure in the vertical direction c together with the top block 80, avoiding the bending or damage of the support due to long-term bearing of concentrated load, and ensuring the uniformity of the overall force of the pull-out bracket, further improving the stability and service life of the structure.

[0102] In combination Figure 7 and Figure 8 , Figure 7 for Figure 7 An enlarged structural schematic view of B in FIG. 1 is shown. In some embodiments, the mutually close surfaces of the first guide 40 and the second guide 50 are respectively provided with a sliding groove 60 extending in the first horizontal direction a, and the mutually far surfaces of the first sliding member 11 and the second sliding member 12 are respectively provided with a sliding block 111, which is slidingly arranged in the sliding groove 60, so as to slidingly connect the first sliding member 11 and the first guide 40, and slidingly connect the second sliding member 12 and the second guide 50.

[0103] Specifically, the sliding fit between the first sliding member 11 and the first guide member 40 and the sliding fit between the second sliding member 12 and the second guide member 50 can be achieved in various ways, such as a pulley and a slide rail, a sliding block 111 and a slide groove 60, etc. In the embodiment of the present application, the mutually approaching surfaces of the first guide member 40 and the second guide member 50 are the inner side surfaces, and the slide grooves 60 extending along the first horizontal direction a are machined on the inner side surfaces, respectively. The slide grooves 60 can be groove structures with a rectangular, T-shaped or dovetail-shaped cross section, and the length of the slide grooves 60 is slightly longer than the maximum stroke of the pull-out bracket, so as to ensure that the pull-out bracket can move smoothly. The first guide member 40 and the second guide member 50 can be profiles, and the slide grooves 60 can be directly formed when the profiles are formed, which can simplify the production process and reduce the production cost. The mutually remote surfaces of the first sliding member 11 and the second sliding member 12 are the outer side surfaces, and the sliding blocks 111 are fixedly arranged on the outer side surfaces corresponding to the positions of the slide grooves 60. The shape of the sliding blocks 111 matches the shape of the slide grooves 60, for example, when the slide groove 60 is a T-shaped groove, the sliding block 111 is a T-shaped block. When assembling, the sliding block 111 of the first sliding member 11 is embedded in the slide groove 60 of the first guide member 40, and the sliding block 111 of the second sliding member 12 is embedded in the slide groove 60 of the second guide member 50. The sliding block 111 can freely slide in the slide groove 60 along the first horizontal direction a, so as to realize the sliding connection between the first sliding member 11 and the first guide member 40 and between the second sliding member 12 and the second guide member 50. The matching structure of the slide groove 60 and the sliding block 111 can limit the sliding member from the two sides of the horizontal direction, effectively preventing the sliding member from deviating or falling off in the moving process. Meanwhile, the bottom and the side of the slide groove 60 can provide certain support for the sliding block 111, share part of the load in the vertical direction c, and further enhance the stability and carrying capacity of the sliding connection. The processing technology of the slide groove 60 and the sliding block 111 is mature, which is convenient for mass production, and by selecting appropriate matching gaps and lubrication methods, the pull-out bracket can still maintain good sliding smoothness in the long-term use process. In addition, the number of the slide grooves 60 along the vertical direction c can be one, which can facilitate the sliding fit between the first guide member 40 and the first sliding member 11 and between the second guide member 50 and the second sliding member 12. One slide groove 60 can be better processed, which can reduce the production cost, and multiple slide grooves 60 require higher processing precision to avoid the inaccuracy of the matching between the slide groove 60 and the sliding block 111.

[0104] In some embodiments, the mutually approaching surfaces of the first guide 40 and the second guide 50 are respectively provided with a plurality of sliding grooves 60 extending along the first horizontal direction a, and the plurality of sliding grooves 60 are spaced apart along the vertical direction c. The mutually receding surfaces of the first sliding member 11 and the second sliding member 12 are respectively provided with sliding blocks 111, and the sliding blocks 111 are spaced apart along the vertical direction c. There are at least one sliding block 111 in each sliding groove 60, so that the first sliding member 11 and the first guide 40 are slidingly connected, and the second sliding member 12 and the second guide 50 are slidingly connected.

[0105] Specifically, the mutually approaching surfaces of the first guide 40 and the second guide 50 can be provided with only one sliding groove 60, or a plurality of sliding grooves 60 spaced apart along the vertical direction c, such as two, three or more. The plurality of sliding grooves 60 are arranged in parallel along the vertical direction c on the inner side surfaces of the first guide 40 and the second guide 50, forming a multi-layer guide structure. Correspondingly, the mutually receding surfaces of the first sliding member 11 and the second sliding member 12 are also spaced apart along the vertical direction c and provided with a plurality of sliding blocks 111 matching the number of sliding grooves 60, and each sliding block 111 is respectively embedded in a sliding groove 60, realizing multi-layer sliding cooperation. The design of the multi-layer sliding grooves 60 and the sliding blocks 111 can significantly increase the contact area and the number of bearing points of the sliding connection structure, so that the vertical direction c load can be dispersed to a plurality of sliding grooves 60 and sliding blocks 111, avoiding the wear or deformation of a single sliding groove 60 and sliding block 111 due to excessive force. That is, when the pull-out support bears a heavier probe assembly 22 or is subjected to a larger vertical pressure during testing, the multi-layer distributed sliding blocks 111 can jointly bear the load, and the friction and support force between each layer of sliding grooves 60 and sliding blocks 111 are more balanced, thereby effectively improving the overall anti-overturning ability and motion stability of the pull-out support. At the same time, the multi-layer guide can further limit the rotational freedom of the pull-out support in the vertical plane, preventing it from being skewed or stuck during movement, and ensuring the straightness and position accuracy of the pull-out movement. In actual application, the number of sliding grooves 60 and sliding blocks 111 can be selected according to the specific equipment specifications and testing requirements. For large or heavy battery production and testing equipment, two or three layers of sliding grooves 60 and sliding blocks 111 can be used to obtain better structural stability and service life. The materials of the sliding grooves 60 and the sliding blocks 111 can be high-strength alloy or wear-resistant plastic. By optimizing the cross-sectional shape of the sliding grooves 60 (such as dovetail groove or T-shaped groove) and the structural design of the sliding blocks 111, the reliability and guiding accuracy of the connection are further enhanced. In addition, the multi-layer sliding grooves 60 also provide convenience for the modular design of the equipment, and the number and spacing of the sliding grooves 60 can be flexibly adjusted according to different load levels, improving the versatility and adaptability of the equipment.

[0106] In combination Figure 8 and ​In some embodiments, the inner wall of the sliding groove 60 has a first planar portion 61 near the upper side edge, which is perpendicular to the vertical direction c; the outer wall of the sliding block 111 has a second planar portion 1111 near the upper side edge, which is also perpendicular to the vertical direction c; wherein the first planar portion 61 and the second planar portion 1111 cooperate to share the vertical upward pressure when the probe assembly 22 is pressed against the battery to be tested (the battery to be tested can be a battery to be tested).

[0107] Specifically, the structure of the sliding groove 60 can be semicircular for easy assembly, or a combination of a round head and a flat surface. In the embodiment of the application, a first planar portion 61 is formed on the inner wall of the sliding groove 60 near the upper side edge, which is perpendicular to the vertical direction c, i.e. in a horizontal state, extending along the first horizontal direction a, constituting a flat support surface on the upper side of the inner side of the sliding groove 60. The outer wall of the sliding block 111 has a second planar portion 1111 near the upper side edge, which is also perpendicular to the vertical direction c, forming a horizontal contact surface matching the first planar portion 61. When the sliding block 111 is inserted into the sliding groove 60, the second planar portion 1111 of the sliding block 111 and the first planar portion 61 of the sliding groove 60 are in close contact or have a small cooperative gap in the vertical direction c. During the battery test, when the probe assembly 22 is pressed against the battery electrode, the battery will generate a vertical upward reaction force on the probe assembly 22, which is transmitted to the sliding block 111 of the first sliding member 11 and the second sliding member 12 through the connecting member 14 and the pull-out bracket. At this time, the second planar portion 1111 of the sliding block 111 will be tightly pressed against the first planar portion 61 of the sliding groove 60, and the vertical upward pressure will be dispersed to the first guide member 40 and the second guide member 50 by the two horizontally matched planar portions, and then transmitted to the mounting bracket 30 by the first guide member 40 and the second guide member 50. This design changes the traditional way of contact force between the sliding groove 60 and the sliding block 111 only through the side or bottom, and directly bears and shares the vertical upward pressure during the test by setting a special horizontal planar portion, effectively avoiding the deformation of the sliding block 111 caused by pure lateral force and the wear of the edge of the sliding groove 60, significantly improving the carrying capacity and fatigue resistance of the sliding connection structure, and ensuring the stability of the guiding accuracy during long-term testing.
