Description

Technical Field

[0001] The utility model relates to the technical field of battery pack detection, in particular to a plug-in type battery pack finished product detection fixture. Background Art

[0002] A battery pack is composed of several cells forming a battery module, and several battery modules forming a large-capacity battery pack. A battery pack, also called a battery PACK, is the final product composed of battery modules, including battery modules, BMS battery management system, battery pack box and other auxiliary components, such as thermal management system, fuse, relay, shunt, connector, smoke sensor, maintenance switch, etc. Among them, BMS is the nerve center of the battery pack; after its production and processing, it will be tested and inspected by testing equipment. During this process, it will be fixed with a testing fixture to assist the equipment in testing the battery pack.

[0003] Since the finished battery pack is composed of several battery modules, when it is tested, when it is placed in the testing fixture as a whole, it will be relatively time-consuming and laborious for operators to operate due to the large volume and weight of the finished battery pack itself, affecting the work efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a plug-in battery pack finished product inspection fixture is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a plug-in battery pack finished product detection fixture to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plug-in battery pack finished product inspection jig, comprising a jig table and a rolling table group, the left and right sides of the jig table are connected to the rolling table group, and a side frame is horizontally installed on the top of the rolling table group, and a blocking frame is arranged on one side of the side frame, a limit frame is arranged in the middle of the rolling table group, and a detection component is installed on one side of the rolling table group, the rolling table group comprises a platform, a rotating roller and a roller, and a rotating roller is installed in the middle of the platform, and rollers are connected to the left and right ends of the rotating roller.

[0007] Furthermore, the rotating rollers are arranged equidistantly in the middle of the platform, and the rotating rollers are arranged on the left and right sides of the fixture table in a sunken structure.

[0008] Furthermore, the roller shaft at one end of the rotating roller is fixed to the side of the platform, and the roller shaft at the other end of the rotating roller is fixed to the side of the fixture table.

[0009] Furthermore, the retaining frame includes a fixing seat, an electric rotating shaft and a retaining rod. The electric rotating shaft is installed on the top of the fixing seat, and the retaining rod is connected to the top of the electric rotating shaft.

[0010] Furthermore, the limit frame includes a limit plate, a bidirectional lead screw, a drive motor and a track seat, the lower ends of the left and right sides of the limit plate are threadedly connected with a bidirectional lead screw, and one end of the bidirectional lead screw is installed with a drive motor through a coupling, and the bottom of the drive motor is connected to the track seat.

[0011] Furthermore, the limit plate is symmetrically connected to the two ends of the bidirectional lead screw, and the bidirectional lead screw and the track seat horizontally penetrate the bottom of the fixture table.

[0012] Furthermore, the detection component includes a base, a detector and a plug connector. The detector is installed in the center of the top of the base, and the top of the detector is connected to the plug connector through a cable.

[0013] Furthermore, a buffer block is installed on the lower end surface of one side of the detection component close to the retaining frame, and damping telescopic rods are horizontally arranged on the left and right sides of the buffer block.

[0014] The utility model provides a plug-in battery pack finished product detection fixture, which has the following beneficial effects:

[0015] 1. The utility model installs rolling table groups on the left and right sides of the jig table, and installs rollers on the sides of the platform and the jig table respectively, so that the rotating rollers are horizontally mounted on the platform, and the surfaces of the rotating rollers are covered with antistatic coatings, so that when the entire battery pack is placed on the surface of the jig table, the operator can use the axial rotation of the rotating rollers on both sides to push the battery pack horizontally into the interior of the entire device, avoiding the inconvenience of putting the battery pack into the jig due to the structure and weight of the battery pack itself, and providing convenience for the testers.

[0016] 2. The utility model installs a limit frame in the rolling table group. As the battery pack is pushed in horizontally, the bidirectional lead screw connected to its power output end rotates axially in the horizontal direction under the operation of the driving motor, thereby driving the limit plates connected at both ends to start translation. The limit plates will move at a uniform speed along the surfaces of the bidirectional lead screw and the track seat at the same time until they are against the side of the battery pack. The use of the above structure can ensure to the greatest extent that after the battery pack is pushed into the interior of the entire fixture, unnecessary shaking can be avoided during the detection process, thereby affecting the detection.

[0017] 3. The utility model installs a buffer block and a damping telescopic rod at the lower end of one side of the detection component respectively, utilizes the kinetic energy absorption of the buffer block and the structural elasticity of the damping telescopic rod itself, so that when the battery pack is pushed on the surface of the fixture table and the rolling table group, the structural collision with the detection component can be avoided, which can effectively avoid unnecessary structural damage to the battery pack itself and the detection component. In addition, by setting a baffle frame on the other side of the rolling table group, as the battery pack is pushed in, the baffle bar that originally maintains the structural lifting state will swing and descend in the horizontal direction by the electric shaft, so as to cooperate with the limit frame, the buffer block and the damping telescopic rod to perform structural limitation in four directions of the battery pack, so as to ensure that when the detector uses the plug connector to connect and detect the battery pack, the battery pack maintains sufficient stability and reduces the structural activity caused by the rolling table group.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figures 1 to 3As shown, a plug-in battery pack finished product inspection fixture includes a fixture table 1 and a rolling table group 2, the left and right sides of the fixture table 1 are connected to the rolling table group 2, and the top of the rolling table group 2 is horizontally installed with a side frame 3, and one side of the side frame 3 is provided with a blocking frame 4, the middle of the rolling table group 2 is provided with a limit frame 5, and one side of the rolling table group 2 is installed with a detection component 6, the rolling table group 2 includes a platform 201, a rotating roller 202 and a roller 203, and the middle of the platform 201 is installed with a rotating roller 202, and the left and right ends of the rotating roller 202 are connected with the roller 203, the rotating rollers 202 are equidistantly arranged in the middle of the platform 201, and the rotating rollers 202 are connected to the rollers 203. The roller 202 is arranged on the left and right sides of the jig table 1 in a sunken structure, the roller 203 at one end of the rotating roller 202 is fixed to the side of the platform 201, and the roller 203 at the other end of the rotating roller 202 is fixed to the side of the jig table 1. The rollers 203 are respectively installed on the sides of the platform 201 and the jig table 1, so that the rotating roller 202 is horizontally mounted on the platform 201. At the same time, the surface of the rotating roller 202 is covered with an anti-static coating, so that when the entire battery pack product is placed on the surface of the jig table 1, the operator can use the axial rotation of the rotating rollers 202 on both sides to push the battery pack horizontally into the interior of the entire device.

[0024] like Figures 1 to 3 As shown, the limit frame 5 includes a limit plate 501, a two-way lead screw 502, a drive motor 503 and a track seat 504. The lower ends of the left and right sides of the limit plate 501 are threadedly connected with the two-way lead screw 502, and one end of the two-way lead screw 502 is installed with the drive motor 503 through a coupling, and the bottom of the drive motor 503 is connected to the track seat 504. The limit plate 501 is symmetrically connected to the two ends of the two-way lead screw 502, and the two-way lead screw 502 and the track seat 504 horizontally penetrate the bottom of the fixture table 1. Under the operation of the drive motor 503, the two-way lead screw 502 connected to its power output end rotates axially in the horizontal direction, thereby driving the limit plate 501 connected at both ends to start translation, and the limit plate 501 will move at a uniform speed along the surface of the two-way lead screw 502 and the track seat 504 at the same time until it is close to the side of the battery pack.

[0025] like Figures 1 to 3As shown, the blocking frame 4 includes a fixed seat 401, an electric shaft 402 and a blocking rod 403, the electric shaft 402 is installed on the top of the fixed seat 401, and the blocking rod 403 is connected to the top of the electric shaft 402, the detection component 6 includes a base 601, a detector 602 and a plug connector 603, the detector 602 is installed in the center of the top of the base 601, and the top of the detector 602 is connected to the plug connector 603 through a cable, and a buffer block 7 is installed on the lower end surface of the side of the detection component 6 close to the blocking frame 4, and the left side of the buffer block 7 Damping telescopic rods 8 are horizontally arranged on both sides of the right side. The kinetic energy absorption of the buffer block 7 and the structural elasticity of the damping telescopic rod 8 can prevent the battery pack from colliding with the detection component 6 when being pushed on the surface of the jig table 1 and the rolling table group 2, thereby effectively avoiding unnecessary structural damage to the battery pack itself and the detection component 6. In addition, by adjusting the electric rotating shaft 402, the blocking rod 403, which originally maintains the structural lifting state, will swing and descend in the horizontal direction, thereby forming a structural shielding.

[0026] In summary, if Figures 1 to 3 As shown, when the plug-in battery pack finished product inspection fixture is used, the electric rotating shaft 402 on the top of the fixing seat 401 is firstly used to axially rotate in the horizontal direction to make the blocking rod 403 connected thereto swing upward to avoid structural interference caused by pushing the battery pack in later;

[0027] Then, under the operation of the external transport equipment, the finished battery pack will be brought to one side of the jig table 1. At this time, the battery pack can be pushed in the horizontal direction to gradually enter the interior of the jig. During this process, the bottom of the battery pack will have structural contact with the surface of the rotating roller 202, and at the same time, under the rotation of the rollers 203 at both ends, the battery pack will rotate axially, thereby generating rolling properties at the bottom of the battery pack, so that the battery pack can slide toward one side of the detection component 6 until it moves to the side of the base 601 provided with the buffer block 7 and the damping telescopic rod 8;

[0028] At this time, the limit frame 5 will operate synchronously. Under the drive of the driving motor 503, the bidirectional lead screw 502 connected thereto starts to rotate horizontally, so that the limit plate 501 with threads connected at both ends simultaneously translates along the surfaces of the bidirectional lead screw 502 and the track seat 504 until it is close to the side of the battery pack.

[0029] Then the retaining frame 4 will perform structural reset, and under the joint action of the retaining frame 4, the limit frame 5, the buffer block 7 and the damping telescopic rod 8, the battery pack will be restricted in the middle of the jig table 1, and then the plug connector 603 will be inserted into the docking port on the surface of the battery pack to connect the detector 602 to it, and then the detection will start until it ends.

[0030] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
