Description

Technical Field

[0001] The utility model belongs to the technical field of battery insulation testing, and particularly relates to a battery insulation testing device. Background Art

[0002] A battery is a device that converts chemical energy into electrical energy. A cup, tank, or other container, or portion of a composite container, contains an electrolyte solution and metal electrodes to generate an electric current. Battery quality and stability are key to ensuring the long-term, reliable operation of equipment. In actual production, insulation testing of batteries is an important means of ensuring product quality and enhancing brand image.

[0003] The existing patent with announcement number CN216485417U discloses a lithium battery insulation test structure, which is equipped with a base, a sliding seat, a multimeter, an extrusion block, a fixed block, a main bevel gear, a slave bevel gear, a rotating wheel, a rotating rod, a threaded ring, an extrusion block, etc. During testing, the staff rotates the rotating wheel to drive the rotating rod, and the engagement of the main bevel gear and the slave bevel gear drives the threaded rod to rotate, thereby driving the sliding seat downward. The downward movement of the sliding seat will drive the synchronous movement of the fixed block. During the movement of the fixed block, it squeezes the inclined surface of the extrusion block, causing the two extrusion blocks to slide toward each other, thereby squeezing and fixing the lithium battery, and ultimately achieving the lithium battery insulation test.

[0004] Since the fixed block and the extrusion block are driven by contact and extrusion, they affect each other. When the multimeter's detection head contacts the battery to be tested, the two extrusion blocks cannot slide toward each other. After the extrusion block has completed the position limit on the battery to be tested, the multimeter's detection head cannot move in the vertical direction. For this reason, the above solution can only detect batteries of a certain model or similar in shape and size to that model, and cannot detect batteries with significantly different shapes. This makes the solution highly limited overall, has a small scope of application, and has poor practical effects. Utility Model Content

[0005] In order to solve the problems existing in the background technology, the utility model provides a battery insulation testing device.

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

[0007] A battery insulation testing device comprises a base, wherein two mounting frames are provided on the top of the base for limited sliding, and the two mounting frames slide toward or away from each other; a first sliding rod is provided on both mounting frames for limited sliding, and clamping plates are fixedly provided on the opposite sides of the two first sliding rods, and the clamping plates correspond to the mounting frames one-to-one, and each clamping plate is connected to the corresponding mounting frame through a first spring; a second sliding rod is provided on the top of each mounting frame for limited sliding, and a sliding sleeve is fixedly provided on the top of each second sliding rod, and a detection head is installed on the top of each sliding sleeve through an adjusting component; the mounting frames correspond to the sliding sleeves one-to-one, and a second spring is provided between each mounting frame and the corresponding sliding sleeve; a roller is provided on each mounting frame, and each first sliding rod is provided with a pull rope, and the end of each pull rope not connected to the first sliding rod passes around the corresponding roller and is connected to the corresponding second sliding rod.

[0008] Furthermore, a slide groove is provided on the top of the base, and a bidirectional screw rod is arranged in the slide groove for horizontal rotation; a motor is fixedly installed on the outer surface of the base, and the output shaft of the motor rotates and extends into the slide groove and is coaxially fixedly connected to one end of the bidirectional screw rod; the two mounting frames correspond one to one with the two threaded sections of the bidirectional screw rod, and each mounting frame is threadedly matched with the corresponding threaded section.

[0010] This application has the following beneficial effects:

[0011] 1. The setting of the first spring can ensure that the clamping plate contacts the battery to be tested first.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0020] like Figure 1-Figure 3 As shown, the technical solution adopted by the present invention is as follows: a battery insulation test device includes a base 1, a horizontally defined chute 2 at the top of the base 1, a horizontally rotatable bidirectional screw 14 disposed within the chute 2, and both ends of the bidirectional screw 14 are rotatably connected to the base 1. A motor 13 is fixedly mounted on the outer surface of the base 1, and the output shaft of the motor 13 is coaxially fixedly connected to one end of the bidirectional screw 14.

[0021] Two mounting frames 11 are slidably mounted on the top of the base 1. The bottoms of both mounting frames 11 are restrained and slidably mounted within the chute 2. The two mounting frames 11 correspond one-to-one with the two threaded sections of the bidirectional screw 14. Each mounting frame 11 is threadedly engaged with the corresponding threaded section. The mounting frames 11, bidirectional screw 14, and ball bearings form a ball screw pair. When the motor 13 is activated, the output shaft of the motor 13 drives the bidirectional screw 14 to rotate, thereby driving the two mounting frames 11 to slide toward or away from each other on the top of the base 1.

[0022] The ends of the two mounting frames 11 that are away from each other are both open, and the ends of the two mounting frames 11 that are close to each other are both horizontally limited and slide through a first slide bar 12. The two first slide bars 12 are arranged facing each other, and the ends of the two first slide bars 12 that are close to each other penetrate one end of the mounting frame 11 and are fixed with a clamping plate 3. The ends of the two first slide bars 12 that are away from each other are both T-shaped.

[0023] The clamping plates 3 correspond to the mounting frames 11 one by one, and a first spring 4 is provided between each clamping plate 3 and the corresponding mounting frame 11. The first spring 4 is sleeved on the outer surface of the first slide bar 12, with one end of the first spring 4 fixedly connected to the clamping plate 3 and the other end of the first spring 4 fixedly connected to the mounting frame 11.

[0024] Several second slide bars 6 are positioned and slidably mounted on the top of each mounting frame 11. These second slide bars 6 consist of two vertical plates and a horizontal plate, forming a U-shape. The tops of the vertical plates of all second slide bars 6 on the same mounting frame 11 slide through the top of the mounting frame 11 and are fixedly connected to the same sliding sleeve 7. Each sliding sleeve 7 is fixedly mounted with a detection head 9 via an adjustment assembly.

[0025] The adjustment assembly includes a limit screw 10. Each sliding sleeve 7 slides horizontally through a slide 8, with a detection head 9 mounted at the bottom. Each sleeve 7 has a threaded hole at the top, into which the limit screw 10 engages. The operator can adjust the position of the detection head 9 by moving the slide 8. Once the slide 8 is positioned correctly, the limit screw 10 is rotated to press against the slide 8, thereby securing the adjusted slide 8.

[0026] The number of sliding sleeves 7 and mounting frames 11 is equal and corresponds one to one. A second spring 5 is provided between each sliding sleeve 7 and the corresponding mounting frame 11. The second spring 5 is sleeved on the outer surface of the second slide rod 6. One end of the second spring 5 is fixedly connected to the bottom of the sliding sleeve 7, and the other end of the second spring 5 is fixedly connected to the top of the mounting frame 11.

[0027] Each mounting frame 11 is rotatably mounted with a plurality of rollers 15, and each first slide bar 12 is fixedly mounted with a plurality of pull cords 16 at the T-shaped end. The rollers 15, pull cords 16, and second slide bars 6 are provided in equal numbers and correspond one to one. The end of each pull cord 16 not connected to a first slide bar 12 passes over the corresponding roller 15 and is fixedly connected to the corresponding second slide bar 6.

[0028] Working Principle: When testing is required, place the battery on top of base 1, between two clamping plates 3. Start motor 13, and its output shaft rotates bidirectional screw 14. This rotation drives two mounting frames 11 toward each other on top of base 1. The two mounting frames 11, via first spring 4, push the two clamping plates 3 toward each other. As the two clamping plates 3 approach, they clamp and limit the battery to be tested.

[0029] When the clamping plate 3 contacts the surface of the battery to be tested, the clamping plate 3 does not slide due to the contact with the surface of the battery, and the two mounting frames 11 continue to approach each other under the drive of the motor 13, and the compression deformation of the first spring 4 gradually increases.

[0030] Since the clamping plate 3 remains stationary during this process, the two first slide bars 12 also do not slide. As the two mounting frames 11 approach each other, the second slide bar 6 pulls the pull cord 16, causing it to slide downward, thereby driving the test head 9 downward to contact the battery's test point, thereby testing the battery's insulation. During this process, the compression deformation of the second spring 5 gradually increases.

[0031] At the same time, the operator can also adjust the position of the detection head 9 by moving the slide 8, and after adjusting the position of the slide 8, rotate the limit screw 10 so that the limit screw 10 presses against the slide 8, thereby limiting the adjusted slide 8 and further improving the applicability of the device.

[0032] After the detection is completed, the output shaft of the control motor 13 rotates in the opposite direction, and the output shaft of the motor 13 drives the bidirectional screw rod 14 to rotate in the opposite direction. The rotation of the bidirectional screw rod 14 drives the two mounting frames 11 to move away from each other on the top of the base 1.

[0033] When the bidirectional screw 14 begins to rotate, the two mounting frames 11 slide away from each other, while the two clamping plates 3 do not slide. During this process, the second slide bar 6 slides upward under the elastic action of the second spring 5, and the pull rope 16 gradually returns to its original position. The detection head 9 gradually loses contact with the battery's test point, and the first spring 4 gradually recovers its deformation.

[0034] When the first spring 4 recovers its deformation, the two clamping plates 3 move away from each other, thereby releasing the position limit of the battery to be tested and completing the reset operation.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
