Description

Technical Field

[0001] The utility model belongs to the technical field of cylindrical battery detection, and particularly relates to a cylindrical battery detection fixture tooling. Background Art

[0002] Cylindrical batteries such as cylindrical lithium batteries are batteries with a cylindrical shape. Cylindrical batteries have very wide applications in the industry, such as being used as the power source of new energy devices, such as new energy vehicles, etc.

[0003] At the same time, cylindrical batteries also have very wide applications in daily life. Therefore, cylindrical batteries not only have a large demand in the consumer market, but also have become a clean energy source based on the advantages of long discharge time, short charging time, and recyclability of cylindrical batteries.

[0004] During the production process of cylindrical batteries, it is often necessary to conduct sampling inspections on the produced batteries to determine the qualification rate of the batteries in the production batch. The currently more conventional detection method is power-on detection. Specifically, the battery is placed on the detection fixture, and the positive and negative electrodes on the detection fixture are electrically contacted with the battery to determine whether the battery can be normally powered on.

[0005] However, there are some drawbacks in the existing fixtures, resulting in low detection efficiency. Especially in the case of a mass production workshop with a large number of sampled samples, the detection workload is extremely large, as follows:

[0006] Currently, the detection fixture brings the detection plates close to each other manually to clamp the battery and make electrical contact. In the case of a large number of detection samples, the operation efficiency is very low. Moreover, when adjusting the fixture manually, it is difficult to control the operation force well during the operation process. As a result, when the electrodes on the fixture are in electrical contact with the battery, the contact force is insufficient (poor contact, the pressing force of the electrodes on the fixture against the battery is not high), which easily generates electric sparks and poses a certain safety hazard to the safe production of the workshop.

[0007] At the same time, after the detection, the operator needs to unload the batteries one by one, further resulting in too low efficiency. Content of the Utility Model

[0008] Based on the above background, the purpose of the utility model is to provide a cylindrical battery detection fixture tooling.

[0009] To achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A cylindrical battery detection fixture tooling includes a fixture base, and a detection mechanism is slidably and assembledly connected to the top of the fixture base. The detection mechanism includes a positive electrode clamping plate and a cooperating negative electrode clamping plate;

[0011] A number of detection electrodes are assembled and connected to both the positive electrode clamping plate and the negative electrode clamping plate;

[0012] Both the positive electrode clamping plate and the negative electrode clamping plate are slidably assembled on the fixture base through a number of spring sliding structures;

[0013] The detection mechanism further includes a number of pushing components for pushing the positive electrode clamping plate and the negative electrode clamping plate closer to each other;

[0014] The pushing component includes a rotating motor installed at the top of the fixture base, and a pushing arm is fixedly assembled and connected to the output shaft of the rotating motor;

[0015] During the process of the positive electrode clamping plate and the negative electrode clamping plate approaching each other, the rotating motor drives the pushing arm to contact the corresponding positive electrode clamping plate and negative electrode clamping plate, and pushes the positive electrode clamping plate and the negative electrode clamping plate.

[0016] Preferably, spring sliding structures are respectively arranged at the left and right ends of the positive electrode clamping plate and the negative electrode clamping plate.

[0017] Preferably, the spring sliding structure includes a sliding convex plate fixedly connected to the corresponding positive electrode clamping plate and negative electrode clamping plate, and a limiting and guiding column fixedly connected to the top of the fixture base and slidably connected to the sliding convex plate.

[0018] Preferably, a limiting sliding opening is formed on the sliding convex plate, the limiting and guiding column is limited in the limiting sliding opening, a spring is fixedly connected to the limiting and guiding column, and the spring is fixedly connected to the limiting sliding opening.

[0019] Preferably, the cylindrical battery detection fixture tooling further includes a loading mechanism;

[0020] During the detection process, the cylindrical battery is loaded on the loading mechanism, and after the detection is completed, the loading mechanism unloads the battery.

[0021] Preferably, a hinge interface is formed at the center of the top of the fixture base, and the loading mechanism includes a loading plate hinged to the hinge interface and a locking component for locking the loading plate.

[0022] Preferably, a number of loading grooves corresponding to the detection electrodes are formed on the loading plate, and during the detection process, the cylindrical battery is loaded in the loading grooves.

[0023] Preferably, one end of the loading plate is hinged in the hinge interface through a fixed pin shaft;

[0024] The locking component locks at the other end of the loading plate.

[0025] Preferably, the locking component includes a motor, and a locking arm is fixedly assembled and connected to the output shaft of the motor. During the locking process, the locking arm supports at the bottom of the loading plate;

[0026] After the inspection is completed, the motor drives the locking arm to rotate to disengage from the loading plate, and the loading plate flips downward until all batteries fall off the loading plate.

[0027] The utility model has the following beneficial effects:

[0028] 1. During the working process, turn on the rotating motor, and the rotating motor drives the push arm to move in the direction of the positive clamping plate and the negative clamping plate until it contacts the positive clamping plate and the negative clamping plate. At this time, under the contact driving force, the positive clamping plate and the negative clamping plate slide close to each other. In this process, the sliding convex plate slides relative to the limit guide column, and the spring is stretched.

[0029] 2. When the detection electrodes on the positive and negative clamps are in electrical contact with the battery, the rotating motor is turned off and the detection is performed. The above method can be used in the detection process, and the locking plate contacts the sliding convex plate to position. After the detection is completed, the rotating motor drives the push arm to reset, and under the elastic restoring force of the spring, the positive and negative clamps are automatically reset to prepare for the next detection. The above method not only greatly improves the detection efficiency, but also does not require manual operation. The positive and negative clamps automatically approach and move away to complete the detection.

[0030] 3. The locking assembly includes a motor, and a locking arm is fixedly assembled on the output shaft of the motor. During the locking process, the locking arm is supported at the bottom of the loading plate. After the detection is completed, when the motor drives the locking arm to rotate to separate from the loading plate, the loading plate loses support and flips downward until all batteries fall off the loading plate. Rapid unloading of batteries is achieved through the above method. Brief Description of the Figures

[0041] Embodiment 1

[0042] As Figures 1-5 shown, a cylindrical battery detection fixture tooling includes a fixture base. A detection mechanism is slidably assembled and connected to the top of the fixture base. The detection mechanism includes a positive electrode clamp 1 (front side) and a matching negative electrode clamp 2 (wherein, the positive electrode clamp 1 and the matching negative electrode clamp 2 are made of insulating materials such as plastics and rubbers). Similar to the existing detection fixtures, a plurality of detection electrodes 3 are assembled and connected to both the positive electrode clamp 1 and the negative electrode clamp 2. Similar to the existing fixtures, when the positive electrode clamp 1 and the negative electrode clamp 2 approach each other until the detection electrodes 3 on the positive electrode clamp 1 and the negative electrode clamp 2 are electrically contacted with the positive and negative electrodes of the battery, power-on detection of the battery is achieved.

[0043] Similar to the existing detection fixture, the detection electrodes 3 are connected with wires, which are electrically connected to the detection equipment through the wires, so that when the positive clamp 1 and the negative clamp 2 are close to each other, the battery, the detection electrode 3 and the detection equipment are energized.

[0044] Specifically, the positive electrode clamping plate 1 and the negative electrode clamping plate 2 are slidably assembled on the clamp base through a plurality of spring sliding structures; specifically, the left and right ends of the positive electrode clamping plate 1 and the negative electrode clamping plate 2 are respectively provided with spring sliding structures.

[0045] Specifically, the spring sliding structure includes a sliding convex plate 41 fixedly connected to the corresponding positive electrode clamping plate 1 and the negative electrode clamping plate 2, and the top of the clamp base is fixedly connected to a limiting guide column 42 slidably connected to the sliding convex plate 41 (the top of the above-mentioned limiting guide column 42 is threadedly connected to a locking plate 421, and the bottom of the locking plate 421 is fixedly connected to a screw threadedly connected to the limiting guide column 42, and the locking plate 421 is screwed downward until the locking plate 421 contacts the sliding convex plate 41 to achieve positioning).

[0046] At the same time, a limited sliding opening is provided on the sliding convex plate 41, and the limited guiding column 42 is limited in the limited sliding opening. A spring 43 is fixedly connected to the limited guiding column 42, and the spring 43 is fixedly connected to the limited sliding opening.

[0047] Under normal circumstances, the spring 43 is in a free state.

[0048] The above detection mechanism also includes a plurality of pushing components for pushing the positive electrode clamping plate 1 and the negative electrode clamping plate 2 toward each other; the pushing component includes a rotating motor 51 installed at the top position of the clamp base, and a pushing arm 52 is fixedly assembled and connected to the output shaft of the rotating motor 51.

[0049] During the working process, the rotating motor 51 is turned on, and the rotating motor 51 drives the pushing arm 52 to move in the direction of the positive clamping plate 1 and the negative clamping plate 2 until it contacts the positive clamping plate 1 and the negative clamping plate 2. At this time, under the contact driving force, the positive clamping plate 1 and the negative clamping plate 2 slide close to each other. In this process, the sliding convex plate 41 slides relative to the limiting guide column 42, and the spring 43 is stretched.

[0050] When the detection electrodes 3 on the positive clamping plate 1 and the negative clamping plate 2 are in electrical contact with the battery, the rotating motor 51 is turned off and the detection is performed. The above method can be used in the detection process, and the locking plate 421 contacts the sliding convex plate 41 to position.

[0051] After the test is completed, the rotating motor 51 drives the push arm 52 to reset. Under the elastic restoring force of the spring 43, the positive electrode clamping plate 1 and the negative electrode clamping plate 2 are automatically reset to prepare for the next test.

[0052] The above method not only greatly improves the detection efficiency, but also does not require manual operation. The positive electrode clamp 1 and the negative electrode clamp 2 automatically approach and automatically move away to complete the detection.

[0053] Embodiment 2

[0054] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, the above cylindrical battery detection fixture tooling further includes a loading mechanism. Through the loading mechanism, multiple loaded batteries can be automatically unloaded quickly after detection to prepare for the next detection.

[0055] Specifically, a hinge interface is provided at the center position of the top of the fixture base. The loading mechanism includes a loading plate 6 hinged to the hinge interface and a locking component for locking the loading plate 6.

[0056] Specifically, a number of loading grooves 61 corresponding to the detection electrodes 3 are provided on the loading plate 6 (the longitudinal cross-sectional shape of the loading groove 61 is arc-shaped. After placing the battery, the positive and negative electrodes of the battery correspond to the height of the detection electrodes 3). During the detection process, the cylindrical battery is loaded in the loading groove 61.

[0057] One end of the above loading plate 6 is hinged in the hinge interface through a fixed pin shaft; the locking component is locked at the other end of the loading plate 6.

[0058] Specifically, the locking component includes a motor 71. A locking arm 72 is fixedly assembled and connected to the output shaft of the motor 71. During the locking process, the locking arm 72 supports at the bottom of the loading plate 6; after the detection is completed, when the motor 71 drives the locking arm 72 to rotate away from the loading plate 6, after the loading plate 6 loses support, the loading plate 6 turns downward until all the batteries fall off the loading plate 6.

[0059] The above method realizes the rapid unloading of the battery.

[0060] During the actual working process, in the existing manner, the fixture base is installed on the rack to keep it in a suspended state, and a collection box is placed at the bottom to collect the unloaded batteries.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
