Description

Technical Field

[0001] The present invention relates to battery detection technology, in particular to a lead-acid battery detection system. Background Art

[0002] A battery tester, also known as a battery analyzer or battery analyzer, is a professional analytical testing device used to determine the operating capacity of automotive batteries. Currently, most battery testers on the market rely on manual operation, which not only reduces testing efficiency but also leads to poor results.

[0003] CN114779108B discloses a battery internal resistance tester for testing batteries. When a storage assembly is driven to rotate by a first motor, the battery reaches a cleaning assembly, which then cleans the battery surface. During the cleaning process, the first motor does not need to stop, and the cleaning assembly does not block the battery's rotation. Subsequently, when the first motor drives the battery to rotate to the top, the battery slides on the storage assembly, shaking off the dust removed from the surface to ensure test accuracy. Finally, when the battery reaches an ohmmeter, the positive and negative electrodes of the ohmmeter are connected to the corresponding battery terminals to measure the internal resistance. However, manual operation is required during battery internal resistance testing, which not only affects work efficiency but also poses a safety hazard. Summary of the Invention

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] like Figures 1 to 13 As shown, the lead-acid battery detection system of the present invention includes a first conveyor belt 1, a second conveyor belt 2, and a detection unit 3. The detection unit 3 is used to clamp the batteries 4 conveyed by the first conveyor belt 1 and detect them. The detection unit 3 can evaluate the service life of the batteries 4 and the remaining electrolyte in the batteries 4. The service life is an assessment of the actual usable amount of electricity in the batteries 4 and whether they can be recycled.

[0039] The first conveyor belt 1 is used to deliver the batteries 4 that need to be tested to a designated location. The second conveyor belt 2 is located at the lower end of the first conveyor belt 1 and is used to deliver the tested batteries 4.

[0040] The second conveyor belt 2 is provided with a symmetrically arranged unloading rod 5, and the unloading rod 5 is provided with a pushing rod 6 arranged perpendicularly thereto. Symmetrically arranged notches 10 are provided on both sides of the bottom plate 7, the sliding plate 8 and the mounting body 9. The pushing rod 6 can pass through the notch 10 and push the battery 4 located in the clamping port 11 onto the second conveyor belt 2.

[0041] When the detection is completed, the rotating roller 12 drives the detection unit 3 to rotate. When the battery 4 is rotated to a vertical upward state, that is, the power terminal 13 is facing upward, the second conveyor belt 2 can be started at this time, so that the second conveyor belt 2 drives the unloading rod 5 to move, and the unloading rod 5 drives the pushing rod 6 to push the battery 4 in the clamping port 11 down and move it to the second conveyor belt 2.

[0042] A first motor 15 is mounted at the rear end of the fixed plate 14. A rotating shaft 16 is mounted on the first motor 15. A rotating roller 12 is mounted on the rotating shaft 16. Multiple detection units 3 are mounted on the rotating roller 12. The first motor 15 rotates the rotating shaft 16, which in turn rotates the rotating roller 12, driving the multiple detection units 3 mounted on the rotating roller 12 to rotate as well.

[0043] The detection unit 3 consists of a base plate 7, a baffle 17 and a movable mechanism 18. The baffle 17 is installed at one end of the base plate 7, and the movable mechanism 18 is installed at the other end of the base plate 7. The baffle 17 is located at the opposite end of the movable mechanism 18. When the rotating roller 12 rotates, the movable mechanism 18 slides toward one end of the baffle 17 under the action of gravity, causing the battery 4 to collide with the detection component 19 to evaluate the service life of the battery 4 and the amount of electrolyte.

[0044] The movable mechanism 18 clamps the battery 4 transported from the first conveyor belt 1 , and is driven by the first motor 15 to move toward the baffle 17 .

[0045] Two parallel dovetail grooves 20 are provided on the bottom plate 7. One end of the bottom plate 7 is tangentially connected to the rotating roller 12. The first motor 15 drives the rotating roller 12 to rotate counterclockwise. The dovetail grooves 20 can keep the movable mechanism 18 sliding on the bottom plate 7 so that it will not shift position.

[0046] A symmetrically arranged detection assembly 19 is mounted on baffle 17 and is used to test battery 4. It includes a pressure sensor 21, a movable rod 22, and a contact head 23. The pressure sensor 21 detects impacts on battery 4. The greater the electrolyte content, the heavier the battery 4, and the greater the impact force. Conversely, the impact force is less. The contact head 23 maintains contact with the power terminals 13 on the battery 4 to detect and assess the internal charge.

[0047] The baffle 17 is provided with a mounting slot 24 for placing a pressure sensor 21. The pressure sensor 21 can detect the force of the battery 4 when it is impacted, and then evaluate the quality of the electrolyte in the battery 4 through computer data analysis.

[0048] The movable rod 22 is arranged in the middle of the pressure sensor 21 and passes through the baffle 17. The movable rod 22 and the contact head 23 are connected by a blocking piece 25. A spring 26 is provided between the blocking piece 25 and the pressure sensor 21. The spring 26 is sleeved on the movable rod 22. The contact head 23 remains connected to the power terminal 13 on the battery 4.

[0049] The contact head 23 is provided with multiple elastic arms 27, each of which is provided with a contact arm 28. The contact arm 28 bends toward the center of the contact head 23. The power terminal 13 has one larger end and a smaller end. The larger end is connected to the battery 4, and the diameter of the smaller end is larger than the distance between the contact arms 28. When the power terminal 13 contacts the contact arm 28, the contact arm 28 can contact it and maintain an electrical connection.

[0050] The end of the movable rod 22 away from the blocking piece 25 is provided with an adjusting member 29, which is screwed onto the movable rod 22. Rotating the adjusting member 29 changes the distance between the adjusting member 29 and the baffle 17. One end of the movable rod 22 can be connected to an electric wire to connect to a computer for evaluation.

[0051] The movable mechanism 18 comprises a sliding plate 8, a mounting body 9, a movable member 30, and a control assembly 31 disposed within the mounting body 9. The bottom of the sliding plate 8 is provided with a dovetail block 32 that engages with the dovetail groove 20. The sliding plate 8 is mounted on the base plate 7. The interior of the mounting body 9 is hollowed out to form a mounting area 33. The control assembly 31 is disposed within the mounting area 33 and is used to control the rotation of the movable member 30 on the mounting body 9 and to limit its angle.

[0052] The control assembly 31 is equipped with a third motor 34, a stopper 35, and a positioning member 36. The positioning member 36 is used to limit the position of the movable member 30, allowing it to rotate within the arc-shaped opening 37 but not to escape from the arc-shaped opening 37. The third motor 34 is equipped with a second gear 38. The second gear 38 engages with a second tooth 40 in the arc-shaped slot 39. The stopper 35 is mounted in a second through-arc slot 41. The lower end of the stopper 35 is equipped with a fourth tooth 43 that engages with the first tooth 42. The positioning member 36 is mounted in the first through-arc slot 44. Both ends of the positioning member 36 are connected to the mounting body 9.

[0053] The third motor 34 drives the second gear 38 to rotate, causing the second gear 38 to mesh with the second tooth 40, driving the movable member 30 to rotate within the arc-shaped opening 37, maintaining the movable member 30 tilted, and facilitating the entry of the battery 4 into the clamping opening 11. When the electromagnet 45 is energized, it attracts the magnet 46, compressing the elastic member 47 and maintaining the downward movement of the limiter 35. The first tooth 42 meshes with the fourth tooth 43, limiting the movable member 30 and preventing it from rotating.

[0054] Support plates 48 are provided on both sides of the limit body 35, and a guide rod 49 is provided in the middle of the support plate 48. The lower end of the guide rod 49 is mounted on the sliding plate 8. An elastic member 47 is sleeved on the guide rod 49. One end of the elastic member 47 contacts the support plate 48, and the other end contacts the sliding plate 8. Magnets 46 are also provided on both sides of the support plate 48. An electromagnet 45 is provided on the sliding plate 8, and the electromagnet 45 is located at the lower end of the magnet 46.

[0055] The center of the mounting body 9 is provided with an arc-shaped opening 37 that mates with the arc portion 50. A first through-hole 51 and a second through-hole 52 are provided within the arc-shaped opening 37. The second gear 38 is positioned within the first through-hole 51, and the support plate 48 is positioned within the second through-hole 52. The width of the first through-hole 51 is greater than the width of the second gear 38, while the width of the second through-hole 52 is greater than the thickness of the support plate 48, allowing the support plate 48 to move within the opening. This width is also greater than the distance between the magnet 46 and the electromagnet 45.

[0056] A clamping opening 11 for placing the battery 4 is provided in the center of the movable member 30. The movable member 30 comprises an arc portion 50 and vertical portions 53 at either end of the arc portion 50. The clamping opening 11 is located between the two vertical portions 53. The arc portion 50 is provided with a first through-arc groove 44 and a second through-arc groove 41. An arc groove 39 is also provided on the lower end surface of the arc portion 50. The second through-arc groove 41 is provided with a first tooth 42, and the arc groove 39 is provided with a second tooth 40.

[0057] The middle of the vertical portion 53 is hollowed out to form a cavity 54, and a clamping assembly 55 is provided in the cavity 54. The clamping assembly 55 is provided with a second motor 56, a first gear 57 and a clamping member 58. Rotating rods 59 are provided at both ends of the second motor 56, and the first gear 57 is mounted on the rotating rod 59. The clamping member 58 is mounted on the vertical portion 53 and can slide on the vertical portion 53. The clamping member 58 is provided with a third tooth 60 that cooperates with the first gear 57. The end of the clamping member 58 close to the clamping port 11 is provided with a triangular portion 61, and the triangular portion 61 is provided with a first inclined surface 62 for clamping the battery 4.

[0058] When the second motor 56 is started, it drives the first gear 57 to rotate, so that the first gear 57 pushes the clamping member 58 to move, so that the first inclined surface 62 clamps the edge of the battery 4.

[0059] A guide portion 63 is provided on the vertical portion 53. The guide portion 63 is located in the clamping opening 11. A second inclined surface 64 is provided on the guide portion 63. The first inclined surface 62 and the second inclined surface 64 have opposite inclination directions. When the clamping member 58 is retracted into the cavity 54, as shown in FIG. Figure 12 As shown, it is convenient for the storage battery 4 to enter the clamping port 11. Of course, when the storage battery 4 moves onto the second conveyor belt 2, the clamping member 58 also needs to be retracted into the cavity 54.

[0060] Since the detection unit 3 rotates continuously, it can rotate from a horizontal state to a vertical state, then to a horizontal state, and then to a vertical state. Keeping the first motor 15 rotating counterclockwise, the detection is automated, effectively improving the detection efficiency of the battery 4.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
