[0037] Example:
[0038] Please see Figs. 1-3This application discloses a wire testing fixture, comprising a base 100, two probe testing mechanisms, two test head testing mechanisms, and a drive mechanism 600. A product testing position 101 is provided on the base 100, and a gantry frame 102 is provided beside the product testing position 101. Two probe testing mechanisms are mounted on the gantry frame 102, and two test head testing mechanisms are located below the gantry frame 102. The drive mechanism 600 drives the two test head testing mechanisms to move left and right. Through this structural design, during operation, after the product to be tested is placed in the product testing position 101, the probe testing mechanisms and the drive mechanism 600 drive the test head testing mechanisms to connect with different terminals of the wires inside the product, thereby testing the wires inside the product. This not only simplifies the testing operation but also increases testing efficiency.
[0039] Specifically, there are two probe testing mechanisms, including a first probe testing mechanism 200 and a second probe testing mechanism 300. The first probe testing mechanism 200 includes a first probe 201 and a first cylinder 202 that drives the first probe 201 to move up and down. The second probe testing mechanism 300 includes a second probe 301 and a second cylinder 302 that drives the second probe 301 to move up and down. During operation, the first cylinder 202 drives the first probe 201 to connect with one of the terminals of the wires inside the product, and the second cylinder 302 drives the second probe 301 to connect with one of the terminals of the wires inside the product.
[0040] Specifically, the second cylinder 302 is mounted on a second cylinder mounting plate 303, the second cylinder mounting plate 303 is mounted on a second support plate 1022, and the second support plate 1022 is mounted on the side wall of the crossbeam of the gantry frame 102.
[0041] Specifically, there are two test head testing mechanisms, including a first test head testing mechanism 400 and a second test head testing mechanism 500. The first test head testing mechanism 400 includes a first test head 401 and a third cylinder 402 for driving the first test head 401. The second test head testing mechanism 500 includes a second test head 501 and a fourth cylinder 502 for driving the second test head 501. During operation, the third cylinder 402 drives the first test head 401 to connect with one terminal of the product's internal wiring, and the fourth cylinder 502 drives the second test head 501 to connect with one terminal of the product's internal wiring. The probe testing mechanism and the test head testing mechanism are used to connect different terminals of the product's internal wiring, respectively.
[0042] Specifically, the third cylinder 402 and the fourth cylinder 502 are both tilted, so that the first test head 401 and the second test head 501 are also tilted, for connection testing of the terminals of the wires inside the product that are tilted.
[0043] Specifically, the third cylinder 402 is mounted on a third cylinder mounting plate 403, the fourth cylinder 502 is mounted on a fourth cylinder mounting plate 503, and the third cylinder mounting plate 403 and the fourth cylinder mounting plate 503 are mounted on a movable plate 700.
[0044] Specifically, the movable plate 700 includes a horizontal plate 701 and a vertical plate 702 disposed on one end of the horizontal plate 701 near the drive mechanism 600. A slider 703 is disposed on the lower surface of the vertical plate 702. The slider 703 is slidably mounted on a slide rail 704, which is mounted on the base 100. The drive mechanism 600 includes a linear motor. The output shaft of the linear motor is connected to the vertical plate 702. Since the output shaft of the linear motor is connected to the vertical plate 702, when the linear motor is working, the slider 703 moves linearly back and forth along the slide rail 704, thereby causing the test head testing mechanism on the movable plate 700 to move linearly back and forth.
[0045] Specifically, a first support plate 1021 is provided on the side wall of the crossbeam of the gantry frame 102, which is opposite to the second support plate 1022. A fifth cylinder mounting plate 801 is installed on the first support plate 1021, and a fifth cylinder 802 is installed on the fifth cylinder mounting plate 801. The piston rod of the fifth cylinder 802 is connected to a pressure plate 803. When working, the fifth cylinder 802 drives the pressure plate 803 to move towards the base, thereby restricting the product on the product test position and facilitating the testing of the internal wires of the product.
[0046] Specifically, the base 100 is provided with a mounting groove 103 near the product testing position 101. A sixth cylinder 104 is installed in the mounting groove 103. The piston rod of the sixth cylinder 104 is connected to a ejector pin 105. During operation, the sixth cylinder 104 drives the ejector pin 105 to further fix the product at the product testing position 101, preventing the product on the product testing position 101 from shaking during testing.
[0047] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, simple testing, and high testing efficiency.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
