[0019] The utility model provides a semi-automatic button battery voltage tester having a structure as follows Figure 1 as well as Figure 3 As shown, it includes a base plate 1, a pushing mechanism 2 is installed on one side of the surface of the base plate 1, and the pushing mechanism 2 is composed of a bracket 21, a pushing cylinder 22 and a pushing plate 23. The bracket 21 is fixedly connected to the surface of the base plate 1 by bolts, and the pushing cylinder 22 is installed on the top of the bracket 21, and the pushing plate 23 is fixed to the output end of the pushing cylinder 22; a probe mechanism 4 is fixed to the surface of the pushing plate 23, and the probe mechanism 4 is composed of a probe mounting plate 41, an upper probe 42 and a plastic connecting column 43. The probe mounting plate 41 is fixedly connected to the surface of the pushing plate 23 by bolts, and the four corner positions of the bottom of the probe mounting plate 41 are fixed with plastic connecting columns 43, an upper probe 42 is arranged below the probe mounting plate 41, and the upper probe 42 and the plastic connecting column 43 are fixedly connected to each other, and in the test state, the detection needle of the upper probe 42 contacts the positive electrode of the battery 81 to be tested, so that the upper probe 42 cooperates with the lower probe 7 for voltage testing of the battery 81 to be tested.

[0020] During implementation, the pushing cylinder 22 on the surface of the bracket 21 drives the pushing plate 23 to move, and the movement of the pushing plate 23 will drive the measuring needle mounting plate 41 downward. The measuring needle mounting plate 41 moves downward, drives the upper measuring needle 42 to contact the positive electrode of the battery to be tested 81 and then continues to move downward so that the spring inside the measuring needle is compressed. Then the measuring needle mounting plate 41 pushes the downward push plate 51 downward until the lower measuring needle 7 contacts the negative electrode surface of the battery to be tested 81, and then the voltage measuring machine is turned on to test the battery voltage and current.

[0021] Furthermore, if Figure 2 as well as Figure 4 As shown, a carrier plate 3 is also provided above the base plate 1, and the four corner positions of the carrier plate 3 are interconnected with the base plate 1 through a return mechanism 6. The return mechanism 6 is composed of a lower bushing flange 61, a double-section elastic column 62 and an upper bushing flange 63. Four groups of lower bushing flanges 61 are provided, and the four groups of lower bushing flanges 61 are fixedly connected to the bottom of the base plate 1, and the top ends of the lower bushing flanges 61 pass through the base plate 1 and are plugged with the double-section elastic column 62. Four groups of upper bushing flanges 63 are provided, and the four groups of lower bushing flanges 61 are fixedly connected to the surface of the carrier plate 3, and the top ends of the double-section elastic columns 62 are fixedly connected to the surface of the upper bushing flange 63. A clamp 8 is fixed to the surface of the carrier plate 3, and a plurality of groups of batteries 81 to be tested are placed on the surface of the clamp 8.

[0022] During implementation, the pushing cylinder 22 drives the upper measuring needle 42 to return, and the placing carrier plate 3 returns under the reaction force of the returning mechanism 6. When the returning mechanism 6 is implemented, the double-section elastic column 62 is compressed. After the upper measuring needle 42 returns, the reaction force of the double-section elastic column 62 will cooperate with the lower bushing flange 61 and the upper bushing flange 63 to automatically return the placing carrier plate 3.

[0023] Furthermore, if Figure 2 As shown in the figures, a positioning mechanism 5 is further provided on the surface of the placement carrier 3, and the positioning mechanism 5 is used for the positioning work of the fixture 8. The positioning mechanism 5 includes a downward push plate 51, a positioning baffle 52 and a positioning bar 53. The downward push plate 51 is provided with two groups, and the two groups of downward push plates 51 are respectively fixedly connected to the left and right sides of the placement carrier 3 by bolts, and a positioning baffle 52 is fixed between adjacent downward push plates 51. A positioning bar 53 is fixed to one side of the downward push plate 51 by screws, and the positioning bar 53 and the positioning baffle 52 are respectively in contact with two sides of the battery 81 to be tested. The placement carrier 3 and the positioning baffle 52 are used to position the battery 81 to be tested; a lower measuring needle 7 is fixed on the surface of the bottom plate 1, and the detection needle of the lower measuring needle 7 penetrates the placement carrier 3 and contacts the negative electrode of the battery 81 to be tested.

[0024] During implementation, the battery 81 to be tested is placed in the battery slot in the fixture 8, and then the fixture 8 is placed on the surface of the carrier 3. It is positioned by the positioning mechanism 5. When the positioning mechanism 5 is implemented, the two sides of the fixture 8 are close to the positioning bar 53 and the positioning baffle 52 between the adjacent downward push plate 51.

[0025] Working principle: During the test, the battery 81 to be tested is placed in the battery slot in the fixture 8, and then the fixture 8 is placed on the surface of the carrier plate 3. It is positioned by the positioning mechanism 5. When the positioning mechanism 5 is implemented, the two sides of the fixture 8 are close to the positioning strip 53 and the positioning baffle 52 between the adjacent downward push plates 51, and then the pushing cylinder 22 on the surface of the bracket 21 drives the push plate 23 to move. When the push plate 23 moves, it will drive the measuring needle mounting plate 41 downward. The measuring needle mounting plate 41 moves downward and drives the upper measuring needle 42 to contact the positive electrode of the battery 81 to be tested and then continue to move downward so that the spring in the measuring needle is compressed. Then the measuring needle mounting plate 41 pushes the downward push plate 51 downward until the lower measuring needle 7 contacts the negative electrode surface of the battery 81 to be tested, and then the voltage measuring machine is connected to test the battery voltage and current.

[0026] After the test is completed, the cylinder 22 is pushed to drive the upper measuring needle 42 to return, and the carrier plate 3 returns under the reaction force of the return mechanism 6. When the return mechanism 6 is implemented, the double-section elastic column 62 is compressed. After the upper measuring needle 42 returns, the reaction force of the double-section elastic column 62 will cooperate with the lower bushing flange 61 and the upper bushing flange 63 to automatically return the carrier plate 3, and finally complete the voltage test of the button battery.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
