Description

Technical Field

[0001] This invention belongs to the field of screening device technology, and in particular relates to a battery current collector screening device. Background Technology

[0002] A battery current collector (also known as a battery electrode or battery current source) is a device that collects or distributes current between the electrodes of a battery cell or battery pack. It typically consists of current collector bars, terminals, and insulating materials, and is widely used in transportation, energy storage systems, and the power industry.

[0003] The main function of a battery current collector is to connect the wires inside individual battery cells to the entire battery pack, and to collect the current into a common current collector. After passing through the current collector, the current is then distributed to the external circuit through the terminals. This device allows the battery cells in the battery pack to work more coordinatedly, thereby achieving maximum power and energy conversion efficiency.

[0004] The current capacity of the battery current collector should match the required battery operating current. If the current is too high or too low, it will affect the battery performance and lifespan. However, existing battery current collector screening devices have low detection efficiency and are not convenient for automatically classifying qualified and unqualified battery current collectors after detection, resulting in high manual labor intensity.

[0005] To address this problem, we propose a battery current collector screening device. Summary of the Invention

[0015] According to the above-mentioned battery current collector screening device, the upper end of the base is provided with a sliding groove that communicates with the upper side of the limiting groove. The sliding seat slides in cooperation with the sliding groove, and the width of the sliding groove is greater than the width of the limiting groove.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1-5 As shown, a battery current collector screening device includes a support platform 1, a conveying component 2 is provided at the upper end of the support platform 1, a battery current collector body 3 is placed at the upper end of the conveying component 2, the conveying component 2 includes two conveying rollers, and a conveying belt is rotatably arranged between the two conveying rollers to transport the battery current collector body 3 placed on the upper end of the conveying belt. A drive motor is installed at the rear end of one of the conveying rollers. The conveying component 2 is a known prior art, and its structure and working principle will not be described in detail here.

[0030] Two guide plates 12 are symmetrically arranged on the front and rear sides of the conveying component 2 at the upper end of the support platform 1. The two guide plates 12 guide the battery current collector body 3 and prevent the battery current collector body 3 from deviating from the route during the conveying process.

[0031] A gantry frame 4 is fixedly installed on the right side of the support platform 1. A U-shaped conduit 5 is fixedly installed inside the gantry frame 4. An electric wire 6 is installed inside the U-shaped conduit 5. Two connecting electrodes 8 are symmetrically connected to both ends of the electric wire 6. An installation box 9 is fixedly connected to the lower end of the gantry frame 4. A light bulb 7 is fixedly installed on the inner top wall of the installation box 9 through an installation plate. The light bulb 7 is electrically connected to the electric wire 6, which converts the current passing through the battery current collector 3 into the brightness of the light bulb 7, so as to more intuitively judge the current capacity of the battery current collector 3.

[0032] A light-blocking film 10 is fixedly adhered to the inner peripheral wall of the mounting box 9 to prevent external light from interfering with the brightness detection inside the mounting box 9, thereby making the brightness detection inside the mounting box more accurate.

[0033] A brightness detector 11 is fixedly installed on the inner bottom wall of the mounting box. This instrument uses the photoelectric conversion principle and adopts a high-precision silicon photocell as the sensing element. The light signal is converted into an electrical signal by a professionally designed cosine corrector and a specially made high-efficiency filter. After being processed by a highly integrated circuit, a continuous linear proportional signal is output. Using the brightness detector 11, the brightness of the mounting box 9 can be detected in real time.

[0034] A mounting block 13 is fixedly connected to the upper end of the gantry frame 4. A guide groove 14 is provided at the right end of the mounting block 13. A limit plate 15 is slidably connected to the guide groove 14. A spring 16 is fixedly connected between the limit plate 15 and the guide groove 14. A baffle 17 is fixedly connected to the lower end of the limit plate 15. The baffle 17 includes a first sliding plate 171 and a second sliding plate 172 fixedly connected from left to right. The width of the second sliding plate 172 is smaller than the width of the first sliding plate 171. The shape of the guide groove 14 is adapted to the shape of the baffle 17. The limit plate 15 can prevent the baffle 17 from detaching from the lower end of the guide groove 14. The width of the second sliding plate 172 is smaller than the width of the first sliding plate 171 to ensure that the baffle 17 detaches from the right end of the guide groove 14.

[0035] A lever 18 is fixedly connected to the right end of the baffle 17, and a vertical plate 19 is fixedly connected to the right end of the mounting block 13. A first rotary motor is fixedly installed at the rear end of the vertical plate 19. A rotating shaft 20 is fixedly connected to the output end of the first rotary motor. A rotating wheel 21 is fixedly connected to the outside of the rotating shaft 20. A rotating plate 22 is fixedly connected to the outside of the rotating wheel 21. The first rotary motor is a slow-speed rotary motor.

[0036] A collection component is provided at the right end of the support platform 1. The collection component includes a base 23, and a second rotary motor 24 is installed inside the base 23. A brightness detector 11 is connected to a controller. The controller is electrically connected to the second rotary motor 24. The brightness of the light bulb 7 is detected by the brightness detector 11 to determine the current capacity of the battery current collector body 3. When the brightness exceeds the normal operating range, the controller controls the second rotary motor 24 to drive the lead screw 26 to rotate.

[0037] The output end of the second rotary motor 24 is fixedly connected to a reciprocating lead screw 26. The upper end of the base 23 is provided with a limiting groove 25 to the right of the second rotary motor 24. The reciprocating lead screw 26 is rotatably engaged with the limiting groove 25. The rod body of the reciprocating lead screw 26 is slidably sleeved with a slider 27. The limiting groove 25 is square in shape and is slidably engaged with the slider 27, so that the slider 27 can slide when the reciprocating lead screw 26 rotates.

[0038] A connecting block 28 is fixedly connected to the upper end of the slider 27, and a sliding seat 29 is fixedly connected to the upper end of the connecting block 28. A sliding groove 30 communicating with the upper side of the limiting groove 25 is opened at the upper end of the base 23. The sliding seat 29 and the sliding groove 30 slide together. The sliding groove 30 can limit the sliding seat 29 and provide guidance for the sliding of the sliding seat 29.

[0039] The width of the slide groove 30 is greater than the width of the limiting groove 25 to prevent the sliding seat 29 from disengaging from the slide groove 30.

[0040] The upper end of the sliding seat 29 is provided with a receiving groove 31. The upper end of the receiving groove 31 is connected to a first collection box 32 and a second collection box 33 from left to right. The first collection box 32 and the second collection box 33 are used to collect unqualified battery current collector bodies 3 and qualified battery current collector bodies 3, respectively.

[0041] The working principle of this invention is as follows:

[0042] In use, the testing personnel place a battery current collector 3 on the upper end of the conveyor belt of the conveyor assembly 2 at regular intervals. Under the guidance of the two guide plates 12, the conveyor route will not deviate and it will move to the right until it comes into contact with the baffle 17. At this time, the battery current collector 3 stops moving to the right. At this time, the wire 6 forms a closed circuit with the battery current collector 3 through the two connecting electrodes 8. Since the battery current collector 3 and the light bulb 7 are connected in series, the current in the series circuit is equal everywhere. The current capacity of the battery current collector 3 is detected by the brightness of the light bulb 7. Then, the first rotary motor drives the rotating shaft 20 to rotate, which drives the rotating wheel 21 to rotate clockwise, drives the rotating plate 22 to move the baffle 18, and drives the baffle 17 to move upward. The spring 16 is compressed, so that the baffle 17 is free from the obstruction to the movement of the battery current collector 3, and the battery current collector 3 continues to be conveyed to the right into the collection assembly.

[0043] During testing, if the brightness detector 11 detects that the brightness is too high or too low, the controller controls the second rotary motor 24 to drive the reciprocating screw 26 to rotate, causing the slider 27 to slide. Through the connecting block 28, the sliding seat 29 moves back and forth once, conveying the unqualified battery current collector body 3 to the first collection box 32. When the brightness is within the normal range, the battery current collector body 3 is conveyed to the upper end of the second collection box 33.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
