DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] As Figure 1 shown, the embodiment of the present application discloses a capacitance and key power-on test equipment, which comprises a rack 1, wherein the rack 1 is provided with an electrical test tool 2 for placing products, one side of the electrical test tool 2 is provided with a capacitance test mechanism 3 for pressing and testing the capacitance end of the product, and the lower end of the electrical test tool 2 is provided with a power-on detection mechanism for power-on detection of the test line on the product. The power-on detection mechanism comprises a wire feeding mechanism 4 for pulling down and feeding forward the test line, and further comprises a test line detection mechanism 5 located on one side of the wire feeding mechanism 4.

[0026] Specifically, the product is first placed on the electrical test tool 2, then the capacitance test mechanism 3 starts to work to test the capacitance of the product and determine whether the capacitance value is within the specified range. At the same time, power-on detection is performed, the wire feeding mechanism 4 pulls down and feeds forward the test line to the test line detection mechanism 5 for power-on detection, and after successful power-on, the key on the product is pressed to observe the screen to realize key detection.

[0027] The design of the structure can realize the test of the capacitance of the product and the power-on test of the test line of the product, thereby effectively improving the test efficiency and accuracy.

[0028] In the embodiment, the wire feeding mechanism 4 comprises a driving plate 41, the bottom of the driving plate 41 is provided with a first three-dimensional driving mechanism 42 for driving the driving plate 41 to move in three-dimensional directions, the driving plate 41 is provided with a first driving block 43, and the first driving block 43 is provided with a vacuum suction port.

[0029] Specifically, when the test line is detected, the first three-dimensional driving mechanism 42 drives the first driving block 43 to move to the lower side of the product test line, and then absorbs and pulls the product test line to move backward first, and then drives the product test line to move forward to the test line detection mechanism 5.

[0030] The above method can ensure that the test line remains stable during movement, avoiding detection errors caused by shaking or position deviation. At the same time, the design of the vacuum suction port enhances the adsorption capacity of the test line, making it more accurate and reliable during pulling and forwarding. In addition, the backward movement of the product test line provides space for the forward movement of the test line detection mechanism 5, so that the product test line can be accurately inserted into the test line detection mechanism 5.

[0031] In this embodiment, the test line detection mechanism 5 includes a driving frame 51, a first lower abutting block 52 is arranged on the driving frame 51, a first lower pressing block 53 is arranged above the first lower abutting block 52, a first needle film for contacting the test line is arranged at the bottom of the first lower pressing block 53, a first driving mechanism 54 is installed on the driving frame 51 for driving the first lower pressing block 53 to move downward, and a second driving mechanism 55 is used to drive the driving frame 51 to move horizontally.

[0032] Specifically, when detecting, the second driving mechanism 55 drives the driving frame 51 to move forward, the test line of the product is sent to the first lower abutting block 52, the first driving mechanism 54 drives the first lower pressing block 53 to move downward, and the test line of the product contacts the first needle film to detect the test line.

[0033] The above method can effectively ensure the stability of the contact between the test line and the first needle film, thereby improving the accuracy of the power-on detection. At the same time, the horizontal movement of the driving frame 51 enables the test line to be accurately positioned at the first lower abutting block 52, avoiding detection failure caused by position deviation.

[0034] In this embodiment, a support plate 61 is further arranged below the electrical measurement tool 2, the support plate 61 is located below the product test line, and a third driving mechanism 62 is arranged on one side of the support plate 61 for driving the support plate 61 to move horizontally. Specifically, when the product is placed on the electrical measurement tool 2, the product test line falls on the support plate 61, the end of the product test line extends out of the support plate 61, then the first driving block 43 absorbs the end of the test line, and the third driving mechanism 62 drives the support plate 61 to retreat, so that the first driving block 43 can drive the test line to move backward.

[0035] The support plate 61 is arranged in the structure to support the test line, prevent the test line from being in a drooping state, and ensure that the first driving block 43 can accurately adsorb the test line. When the first driving block 43 adsorbs the test line, the support plate 61 is retracted, and the retracted support plate 61 does not interfere with the subsequent movement of the test line, thereby ensuring that the test line remains stable and accurate during movement.

The capacitance testing mechanism 3 further comprises a fourth driving mechanism 36 mounted on the mounting block 33 and used to drive the second pressing block 35 to perform a downward pressing movement.

[0037] Specifically, when the capacitance is tested, the second lower abutting block 34 is first accurately positioned below the product capacitance through the cooperation of the XY-axis driving mechanism 31 and the first rotary driving mechanism 32. Then, the fourth driving mechanism 36 drives the second pressing block 35 to move downward, so that the second needle film is in close contact with the product capacitance, thereby completing the detection of the capacitance value. In this process, the cooperation of the XY-axis driving mechanism 31 and the first rotary driving mechanism 32 ensures that the second lower abutting block 34 can accurately reach the specified position, avoids errors caused by manual adjustment, and significantly improves the detection efficiency and accuracy.

[0038] In the embodiment, a detection camera is arranged above the capacitance testing structure and is used to detect the position of the capacitance. When the detection camera is positioned at the position of the product capacitance, the XY-axis driving mechanism 31 and the first rotary driving mechanism 32 cooperate to drive the second lower abutting block 34 to move below the product capacitance.

[0039] Specifically, the detection camera accurately captures the position information of the product capacitance through image recognition technology and transmits the information to the control system. The control system automatically adjusts the movement parameters of the XY-axis driving mechanism 31 and the first rotary driving mechanism 32 according to the received data, so as to ensure that the second lower abutting block 34 can be accurately positioned directly below the product capacitance. This automatic positioning method not only reduces manual intervention, but also greatly improves the positioning accuracy and test consistency.

[0043] In the embodiment, the electric testing tool 2 is provided with a plurality of suction disc structures 21 for sucking the product.

[0044] Specifically, when the product is placed on the electric testing tool 2, the suction disc structure 21 automatically starts the suction function, so that the product can be quickly fixed in place, thereby preventing the product from being displaced or shaken during the testing process, and ensuring the stability and accuracy of the testing.

[0045] The application further discloses a capacitor and key power-on testing method, which adopts the capacitor and key power-on testing device.

[0047] Meanwhile, the second lower abutting block 34 and the second lower pressing block 35 can be driven to actively move to the product capacitor through the cooperation of the XY axis driving mechanism 31 and the rotating mechanism in the capacitor test mechanism 3, so that the product does not need to be controlled to move during detection, thereby simplifying the structure and making the overall operation more convenient.
