[0002] The size and taper of the positive and negative terminals of the battery must meet the national standard requirements to ensure that the wiring clips are in close contact with the battery terminals; otherwise, poor wiring contact and loose connections may occur, leading to poor starting, and in severe cases, sparks and flames.

[0003] In the prior art, the Chinese utility model with publication number: CN215728676U discloses a voltage detection device for lead-acid battery processing, including a pressure plate, a drawer plate, a squeeze contact mechanism, a wire and a voltage detector. A drawer plate is inserted at one end of the pressure plate, and a squeeze contact mechanism is provided on both the pressure plate and the drawer plate. The squeeze contact mechanism includes a fixed cylinder, a conductive rod, a spring, a first copper sheet and a contact head. A fixed cylinder is inserted at the outer ends of the pressure plate and the drawer plate, and a conductive rod is inserted in the fixed cylinder. A spring is mounted on the conductive rod, and a contact head is fixed to the bottom end of the conductive rod. A wire is provided at the top of the fixed cylinder, and the other end of the wire is connected to a voltage detector. Beneficial effects: This voltage detection device does not require the use of a clamp to clamp the terminal to contact and energize it, and can perform rapid detection on small lead-acid batteries. The detection method is simple, the operation is simple, and it saves time and effort. It is convenient for rapid detection on the production line, and the detection speed is fast and the efficiency is high, which greatly improves the processing efficiency.

[0004] Although the detection device in the above technical solution is convenient for testing batteries of different models, it still requires manual alignment of the detection end, which has high labor costs and reduces the efficiency of through-wall welding point detection after battery manufacturing. Therefore, we need to propose a fully automatic non-destructive testing machine. Utility Model Content

[0012] 1. The utility model mainly adopts the coordination among the ammeter and voltmeter, the servo motor, the detection mold, the first needle, the second needle and the clamping cylinder. The battery is clamped and fixed by the clamping cylinder. The servo motor drives the detection module mold to rise and fall, thereby making the first needle and the second needle touch the welding point.

[0018] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3The utility model provides a technical solution: a fully automatic non-destructive testing machine, comprising a testing frame 1, a conveying device 9 and a mounting plate 2 provided on the testing frame 1, the mounting plate 2 being arranged directly above the conveying device 9, a servo motor 3 being provided on the mounting plate 2, and the servo motor 3 being transmission-connected to a testing mold 4, multiple groups of first needles 5 and multiple groups of second needles 6 being detachably connected in the testing mold 4, an ammeter and voltmeter 7 being provided at the upper end of one side of the testing frame 1, a pneumatic part 8 being provided at the lower end of one side of the testing frame 1, two groups of clamping cylinders 13 being symmetrically provided on the conveying device 9, and the two groups of clamping cylinders 13 being arranged directly below the testing mold 4, multiple groups of first needles 5 and multiple groups of second needles 6 being alternately arranged, and a horizontal rod for sliding and plugging multiple groups of first needles 5 and multiple groups of second needles 6 is provided on the testing mold 4.

[0020] Two sets of guide frames 15 are symmetrically arranged on the conveying device 9, and two sets of clamping cylinders 13 are respectively arranged under the two sets of guide frames 15. The guide frames 15 limit the movement direction of the battery to avoid position displacement when the battery moves, thereby improving the accuracy of welding point detection. In addition, the spacing of the guide frames 15 is adjustable and is suitable for lead-acid batteries of different specifications.

[0021] The conveying device 9 is provided with a first photoelectric switch 10, a second photoelectric switch 12, a feed cylinder 11, and a blocking cylinder 14. The first photoelectric switch 10, the feed cylinder 11 and the second photoelectric switch 12 are alternately arranged. The first photoelectric switch 10 is used to facilitate positioning of the battery movement position, thereby controlling the feed cylinder 11 to block subsequent battery input, and the second photoelectric switch 12 is used to position the battery when it is moved to the detection station. While controlling the conveying device 9 to stop, the battery is clamped by two sets of clamping cylinders 13 to improve the stability of battery solder joint detection.

[0022] An unqualified platform 18 is detachably connected to the conveying device 9, and an ejection cylinder 17 is fixedly connected to the conveying device 9. A third photoelectric switch 16 is provided on the ejection cylinder 17. The ejection cylinder 17 and the unqualified platform 18 are arranged in the same plane. The start and stop of the ejection cylinder 17 is controlled by the third photoelectric switch 16 to facilitate the diversion of qualified or unqualified batteries.

[0023] The first photoelectric switch 10 is arranged parallel to the Z-axis plane, and the second photoelectric switch 12 and the third photoelectric switch 16 are both arranged to intersect with the Z-axis plane. The second photoelectric switch 12 is used to control the conveying device 9 to stop when the battery is moved to the inspection station, and at the same time control the clamping cylinder 13 to clamp the battery, thereby improving the stability of the battery during inspection.

[0024] When in use, set the parameters of the servo motor 3, place the battery on the conveyor belt, and open the two sets of clamping cylinders 13 to clamp the battery, and at the same time adjust the position of the first needle 5 and the second needle 6 on the detection mold 4 to match the test point on the battery (different types of batteries need to readjust the setting position parameters), then take out the battery, start the equipment, and the conveying device 9 drives the battery to move on the conveyor belt. When passing the first photoelectric switch 10, the first photoelectric switch 10 controls the feeding cylinder 11 to open to allow the battery to pass, and the feeding cylinder 11 is closed after the battery passes to prevent subsequent batteries from entering. After the second photoelectric switch 12 detects the battery, it controls the two sets of clamping cylinders 13 to clamp the battery, and after the servo motor 3 drives the detection mold 4 to descend to the specified height, the first needle 5 and the second needle 6 are clamped. The second needle 6 contacts the solder joint on the battery, thereby turning on the power and setting the detection time. The microvoltage on the solder joint is detected by the first needle 5 and the second needle 6, and the detection value is monitored by the current and voltage meter 7. If it exceeds the value, it is unqualified, and if it is lower than the value, it is not detected and needs to be re-tested. After the detection is completed, the servo motor 3 drives the detection mold 4 to rise, so that the two sets of clamping cylinders 13 release the battery and move to the third light band switch under the action of the conveying device 9. When the battery is qualified, the push-out cylinder 17 is not started. When the battery is unqualified, the third photoelectric switch 16 detects the battery and controls the push-out cylinder 17 to push the unqualified battery to the unqualified platform 18, thereby completing the qualified performance test of the solder joint during battery manufacturing, improving the detection efficiency of the battery, and reducing the workload of the staff.
