Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a square battery cover plate high-voltage detection device. Background Art

[0002] After the battery cover is assembled to the battery, if the insulating seal between the positive pole head and the cover surface is not properly installed or the insulating seal does not meet product requirements, it is easy to cause high-voltage breakdown between the positive pole head and the cover surface, which may cause the battery to catch fire or explode, leading to a safety accident. Therefore, after the square battery cover is completed, in order to prevent the surface of the battery cover and the positive pole from breaking down and conducting under high-voltage conditions, it is necessary to perform high-voltage testing between the positive pole and the cover surface. Currently, the positive pole voltage is generally directly connected to the positive pole, and the negative pole voltage is directly connected to the cover surface. Not only is the testing process unsafe and prone to safety accidents, but the detection efficiency is also low. Utility Model Content

DETAILED DESCRIPTION

[0019] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0021] Example:

[0022] A square battery cover high voltage detection device, please see the attached Figure 1 -Attached Figure 2 As shown, the apparatus comprises a base plate 1 and a cylinder 2 disposed on one side of the base plate 1. The telescopic end of the cylinder 2 is connected to a first bracket 3 and second brackets 4 arranged on both sides of the first bracket 3. Specifically, the square battery cover high-voltage testing equipment also includes a base 5. The base plate 1 is fixedly mounted on the base 5. A cylinder bracket 6 is fixedly mounted on the base 5. The cylinder 2 is fixedly mounted on the cylinder bracket 6. The telescopic end of the cylinder 2 is connected to a mounting plate 7. The first bracket 3 and the second bracket 4 are both fixedly mounted on the mounting plate 7 via brackets. The first bracket 3 and the second bracket 4 can move along the telescopic direction of the cylinder 2 by the extension and contraction of the cylinder 2.

[0023] A pressure column 8 is installed on the first bracket 3, and a negative electrode guide column 9 is fixedly installed on the second bracket 4; an insulating sheath 10 is installed on the bottom plate 1, and a positive electrode guide column 11 arranged opposite to the pressure column 8 is sheathed in the insulating sheath 10, and a positive electrode terminal 11.1 is provided on the positive electrode guide column 11, and a negative electrode terminal 9.1 is provided on the negative electrode guide column 9.

[0024] When the new type is used, turn off the detection power supply, electrically connect the positive pole of the detection power supply to the positive terminal 11.1 of the positive conductor 11, and electrically connect the negative pole of the detection power supply to the negative terminal 9.1 of the negative conductor 9. The contraction section of the operating cylinder 2 contracts and makes room for operation. Figure 3 As shown, the positive contact of the square battery cover 12 is placed on the positive electrode guide 11. As a preferred embodiment, refer to the attached Figure 2 As shown, the insulating sheath 10 is surrounded by limit blocks 13 fixed on the base plate 1 and used to prevent the square battery cover 12 from rotating. After the square battery cover 12 is in place, the telescopic end of the operating cylinder 2 is extended, and the square battery cover 12 is pressed by the pressure column 8. At the same time, the negative electrode guide column 9 abuts against the surface of the square battery cover 12. At this time, the switch of the detection power supply can be turned on, and a detection voltage can be applied between the surface of the square battery cover 12 and the positive contact. If there is no breakdown and conduction, it proves that the insulation between the surface of the square battery cover 12 and the positive contact meets the standard, otherwise it does not meet the standard. The entire test process is simple and convenient, the test efficiency is high, and it can fully guarantee the safety of the test personnel.

[0025] Continue to refer to the attached Figure 5 As shown, in order to further improve the detection efficiency of the present invention, a slot-type photoelectric switch 14 is provided above the first bracket 3, and a trigger piece 3.1 for triggering the switching signal of the slot-type photoelectric switch 14 is provided on the top of the first bracket 3. In this embodiment, when the cylinder 2 retracts, the trigger piece 3.1 extends into the signal slot of the slot-type photoelectric switch 14, and the closing signal of the slot-type photoelectric switch 14 is triggered, thereby controlling the detection power to be turned off. Correspondingly, when the square battery cover 12 is in place, the telescopic end of the cylinder 2 extends, and the trigger piece 3.1 withdraws from the signal slot of the slot-type photoelectric switch 14, and the closing signal of the slot-type photoelectric switch 14 is triggered, thereby controlling the detection power to be turned on. In this embodiment, when the cylinder 2 retracts after the detection is completed, the detection power is automatically turned off, and when the cylinder 2 is extended for detection, the detection power is automatically turned on. This further improves the detection efficiency of the present invention.

[0026] Continue to refer to the attached Figure 4 As shown, in this embodiment, guard plates 15 are respectively provided on both sides and the rear side of the base 5, and a safety grating 16 is also provided on the front side of the base 5, which further improves the safety of the use of the utility model and ensures the safety of the operator.

[0027] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
