Description

Technical Field

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

[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly. It is different from a battery that contains a protection circuit and a shell and can be used directly. The composition of a lithium-ion secondary rechargeable battery is as follows: battery cell + protection circuit board. The rechargeable battery without the protection circuit board is the battery cell. It is the power storage part of the rechargeable battery. The quality of the battery cell directly determines the quality of the rechargeable battery. It has a small particle size, a large specific surface area, a white color, a high purity, and significantly improved electrochemical performance. It can be used in lithium titanate battery materials and lithium cobalt oxide battery materials.

[0003] The patent document with announcement number CN220913296U discloses an operating table for integrated circuit chip testing, which uses a suction cup to absorb the integrated circuit chip, and sets a pulley and a slide rail to stabilize the stability of the scissor-type telescopic frame during the extension and retraction process. A frame is set as its carrier. After the suction cup absorbs the integrated circuit chip, it only needs to rotate the frame and then retract the telescopic rod to place it on the pressure plate to complete the integrated circuit chip removal process. A pressure plate is set to place the integrated circuit chip, and the integrated circuit chip on the pressure plate is pressed by setting a rotating block and a rotating plate. An anti-slip layer is set to prevent the integrated circuit chip from sliding and dislocating. An IC socket is set to perform power-on detection on the integrated circuit chip on the pressure plate. It is only necessary to buckle the rotating plate and the pressure plate with a buckle to move the integrated circuit chip therein to the IC socket through the slide rail 2 and the slider for plugging and power-on detection.

[0004] In the above application, in actual application, although it is only necessary to fasten the rotating plate and the pressure plate with a buckle and move the integrated circuit chip therein to the IC socket through the slide rail 2 and the slider for plug-in power-on detection, in actual application, due to the different sizes of battery cells, it is impossible to adjust them according to the size of the battery cells during the subsequent detection process, which will affect the subsequent installation detection of battery cells of different sizes. Utility Model Content

[0005] The utility model discloses a battery core testing platform, which aims to solve the technical problem of inconvenient adjustment and testing of battery cores according to their sizes.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A battery cell testing platform comprises a base, wherein a movable plate is provided on the upper surface of the base, one side of the movable plate is connected to a testing tube, and a positioning component is provided on the upper surface of the base.

[0008] The positioning assembly includes a card plate fixedly mounted on the base, a groove is opened on one side of the card plate, a plug rod is inserted into the card plate, a baffle is fixedly mounted on the top of the plug rod, a tension spring is arranged around the surface of the plug rod, and a pressure plate is fixedly mounted on the bottom of the plug rod.

[0009] By pulling the baffle on the handle, the rod on the baffle moves up, and the pressure plate moves upward at the same time. When the battery cell is placed inside the groove, the baffle is loosened and the tension spring resets the rod on the baffle, so as to facilitate the subsequent use process to cooperate with the downward pressure plate to press the battery cell, thereby preventing the battery cell from loosening during the subsequent inspection process.

[0010] A cavity is provided on the base, and a slide is slidably connected to the inside of the cavity. A slide rod is fixedly installed on the top of the slide. The top of the slide rod passes through the base and extends to the outside of the base. A screw rod is inserted on the slide, and one end of the screw rod passes through the base and extends to the outside of the base.

[0011] By setting a screw rod and rotating the screw rod, the slide plate on the screw rod will drive the movable plate on the slide rod to move, so as to facilitate the adjustment of the position of the detection tube. When the battery cell is inserted into one side of the card plate, the screw rod can be rotated in the opposite direction so that the other end of the battery cell is inserted into the interior of the detection tube, thereby realizing detection thereof. In this way, the clamping distance of the detection table can be adjusted according to battery cells of different sizes.

[0012] The surface of the screw rod is sleeved with an airbag ring, one side of the airbag ring is fixedly connected to one side of the inner wall of the cavity, one side of the airbag ring is connected to a connecting tube, one end of the connecting tube passes through the base and is connected to the storage cavity opened on the card plate, the interior of the storage cavity is slidably connected to a piston plate, one side of the piston plate is fixedly installed with an extrusion rod, and one side of the extrusion rod is in contact with the surface of the insertion rod.

[0013] By setting up the airbag ring, when the slide plate is squeezed with the airbag ring, the gas in the airbag ring enters the interior of the storage cavity through the connecting tube, and then the extrusion rod on the piston plate is squeezed with the surface of the insertion rod, preventing the subsequent insertion rod from sliding on the card plate.

[0014] In a preferred solution, a support rod is fixedly installed on the bottom of the detection tube, and the bottom of the support rod is slidably connected to the upper surface of the base.

[0015] By providing the support rod, it is convenient to support the bottom of the detection tube during use, thereby preventing the detection tube from being damaged during subsequent use.

[0016] In a preferred solution, a handle is fixedly installed on the top of the baffle, and the surface of the handle is provided with anti-slip grooves. A socket for the insertion rod is provided on the card plate, and the inner wall of the socket is slidably connected to the surface of the insertion rod.

[0018] In a preferred solution, the top of the tension spring is fixedly connected to the bottom of the baffle, and the bottom of the tension spring is fixedly connected to the top of the clamping plate.

[0019] By setting a tension spring, it is convenient to reset the insertion rod on the baffle during use, which also facilitates the subsequent clamping of the battery cell.

[0020] In a preferred solution, a screw hole for the screw rod to pass through is provided on the slide and on one side of the base, and the screw hole is threadedly connected to the screw rod.

[0023] By setting the sleeve, one end of the screw rod can be limited during use to prevent one end of the screw rod from falling off the component during rotation. The setting of the threaded tube and the threaded rod facilitates the height adjustment of the threaded rod and facilitates the subsequent height adjustment of the test bench according to the terrain.

[0024] In a preferred embodiment, a groove is provided inside the pressure plate, a reciprocating spring is fixedly installed on the inner top wall of the groove, an anti-slip plate is fixedly installed on the bottom of the reciprocating spring, the bottom of the anti-slip plate contacts the inner wall of the groove of the card plate, and the anti-slip plate is adapted to the groove on the pressure plate.

[0025] By providing the anti-slip plate and the return spring, the anti-slip effect of clamping the vehicle can be achieved during use.

[0026] As can be seen from the above, the battery cell testing platform provided by the present invention has the following technical effects.

[0027] First: by rotating the screw, the slide on the screw will drive the movable plate on the slide bar to move, so as to facilitate the adjustment of the position of the detection tube. When the battery cell is inserted into one side of the card plate, the screw can be rotated in the opposite direction so that the other end of the battery cell is inserted into the interior of the detection tube, thereby realizing detection. In this way, the clamping distance of the detection table can be adjusted according to battery cells of different sizes.

[0028] Second: by pulling the baffle on the handle, the rod on the baffle moves up, and the pressure plate moves upward at the same time. When the battery cell is placed inside the groove, the baffle is loosened, and the tension spring resets the rod on the baffle, so as to facilitate the subsequent use process to cooperate with the downward pressure plate to press the battery cell, thereby preventing the battery cell from loosening during the subsequent inspection process.
