Description

Technical Field

[0001] This invention relates to the field of screen testing, and particularly to equipment and methods for testing the capacitance and button power-on. Background Technology

[0002] In the field of screen testing, it is necessary to test the capacitance and power-on detection lines connected to the screen. The capacitance test mainly checks whether the capacitance value is within the specified range, while the power-on detection test checks whether the power-on line can accurately conduct electricity. If it can accurately conduct electricity, the button is pressed and the screen feedback is observed to test the button function. Currently, common testing methods are inefficient and cumbersome. At the same time, it is impossible to accurately align the test end during testing, resulting in inaccurate test results and easy misjudgment. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a capacitor and button power-on testing device for accurately testing the test terminals.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a capacitor and button power-on testing device, including a frame, an electrical testing fixture for placing products is provided on the frame, a capacitor testing mechanism for pressing the capacitor end of the product and testing the capacitor end of the product is provided on one side of the electrical testing fixture, and a power-on detection mechanism for detecting the power-on of the test lines on the product is provided at the lower end of the electrical testing fixture.

[0005] The power-on detection mechanism includes a wire feeding mechanism for pulling up and feeding the test wire forward, and a test wire detection mechanism located on one side of the wire feeding mechanism.

[0006] Furthermore, the wire feeding mechanism includes a drive plate, and the bottom of the drive plate is provided with a first three-dimensional drive mechanism for driving the drive plate to move in three-dimensional direction. The drive plate is provided with a first drive block, and the first drive block is provided with a vacuum suction port.

[0007] Furthermore, the first three-dimensional driving mechanism drives the first driving block to move below the product test line, attracts the product test line, and pulls the product test line downward and backward first, and then drives the product test line forward to the test line detection mechanism.

[0008] Furthermore, the test line detection mechanism includes a drive frame, on which a first lower abutment block is provided, a first lower pressing block is provided above the first lower abutment block, and a first needle membrane for contacting the test line is provided at the bottom of the first lower pressing block. It also includes a first drive mechanism mounted on the drive frame for driving the first lower pressing block to perform a downward pressing movement, and a second drive mechanism for driving the drive frame to perform a horizontal movement.

[0009] Furthermore, the second drive mechanism drives the drive frame to move forward, and the product's test line is delivered to the first lower contact block. The first drive mechanism drives the first lower pressure block to press down, and the product's test line contacts the first needle membrane to perform an electrical test on the test line.

[0010] Furthermore, a support plate is also provided below the electrical testing fixture. The support plate is located below the product test line, and a third drive mechanism for driving the support plate to move horizontally is provided on one side of the support plate.

[0011] After the product is placed on the electrical testing fixture, the product test leads fall onto the support plate, with the ends of the product test leads extending out of the support plate.

[0012] Furthermore, the capacitance testing mechanism includes an XY-axis drive mechanism, a first rotary drive mechanism at the drive end of the XY-axis drive mechanism, a mounting block at the drive end of the first rotary drive mechanism, a second lower abutment block on the mounting block, a second lower pressing block above the second lower abutment block, a second pin membrane on the second lower abutment block for contacting the product capacitor, and a fourth drive mechanism mounted on the mounting block for driving the second lower pressing block to perform a downward pressing movement.

[0013] Furthermore, a detection camera for detecting the position of the capacitor is provided above the capacitor testing structure;

[0014] Once the detection camera locates the product capacitor, the XY axis drive mechanism and the first rotary drive mechanism work together to move the second lower abutment block below the product capacitor.

[0015] Furthermore, the electrical testing fixture is provided with a telescopic pressure plate, and also includes a second rotary drive mechanism for driving the telescopic pressure plate to rotate. A lower abutment plate is provided on one side of the electrical testing fixture, and a spring is provided between the lower abutment plate and the electrical testing fixture.

[0016] When the telescopic pressure plate rotates to a horizontal position, it moves to the lower abutment plate.

[0017] Furthermore, the second rotary drive mechanism drives the telescopic pressure plate to perform a rotary smoothing motion above the product capacitor, and the capacitor is flattened under the action of the telescopic pressure plate and the lower abutment plate;

[0019] Furthermore, the electrical testing fixture is equipped with multiple suction cup structures for holding the product in place.

[0020] This invention also discloses a method for testing the energization of capacitors and buttons, using the aforementioned capacitor and button energization testing equipment, comprising the following steps:

[0021] Load the product onto the electrical testing fixture and perform capacitance and power-on tests on the product;

[0022] During capacitance testing, the second rotary drive mechanism drives the telescopic pressure plate to rotate and flatten above the product capacitor. The capacitor is flattened under the action of the telescopic pressure plate and the lower abutment plate. Then, the detection camera detects the position of the capacitor. The XY axis drive mechanism and the first rotary drive mechanism work together to drive the second lower abutment block to move to below the product capacitor. At this time, the lower abutment plate is pressed inward under the action of the second lower abutment block. The product capacitor extends out of the lower abutment plate and falls on the second lower abutment block. The fourth drive mechanism drives the second lower pressure block to press down, so that the product capacitor is in close contact with the second needle film, and tests whether the product capacitor is within the specified range.

[0023] During the power-on test, the first three-dimensional drive mechanism drives the first drive block to move below the product test line, attracts the product test line, and pulls the product test line downward and backward. The second drive mechanism drives the drive frame to move forward, and the first three-dimensional drive mechanism drives the first drive block to move forward, so that the test line is delivered to the first lower abutment block. The first drive mechanism drives the first lower pressure block to press down, and the product test line contacts the first needle membrane to perform a power-on test on the test line. After successful power-on, the button on the product is pressed, and the screen is observed to realize the button test.

[0024] The beneficial effects of this invention are:

[0025] 1. In this structure, the combination of the wire feeding mechanism and the test wire detection mechanism allows the test wires at the bottom of the product to be accurately inserted into the test wire detection mechanism for power-on testing.

[0026] 2. In this structure, the use of the telescopic pressure plate and the lower support plate together can achieve the smoothing operation of the product capacitor, so that the product capacitor can be accurately fed into the capacitor testing mechanism.

[0027] 3. In the capacitance testing mechanism, the cooperation of the XY axis drive mechanism and the rotation mechanism can drive the second lower abutment block and the second lower pressure block to move actively to the product capacitance. Therefore, there is no need to control the product movement during testing, which simplifies the structure and makes the overall operation more convenient. Attached Figure Description

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, embodiments of this application disclose a capacitor and button power-on testing device, including a frame 1. The frame 1 is provided with an electrical testing fixture 2 for placing products. One side of the electrical testing fixture 2 is provided with a capacitor testing mechanism 3 for pressing the capacitor end of the product and testing the capacitor end of the product. The lower end of the electrical testing fixture 2 is provided with a power-on detection mechanism for detecting the power-on of the test lines on the product.

[0039] The power-on detection mechanism includes a wire feeding mechanism 4 for pulling up and feeding the test wire forward, and a test wire detection mechanism 5 located on one side of the wire feeding mechanism 4.

[0040] Specifically, the product is first placed on the electrical testing fixture 2. Then, the capacitance testing mechanism 3 starts working to test the product's capacitance and determine whether its capacitance value is within the specified range. At the same time, a power-on test is performed. The wire feeding mechanism 4 pulls the test wire down and forward to the test wire detection mechanism 5 for power-on testing. After successful power-on, the button on the product is pressed, and the screen is observed to perform button testing.

[0041] This structure is designed to perform both capacitance testing and power-on testing of product test leads, thereby effectively improving testing efficiency and accuracy.

[0042] In this embodiment, the wire feeding mechanism 4 includes a drive plate 41. The bottom of the drive plate 41 is provided with a first three-dimensional drive mechanism 42 for driving the drive plate 41 to move in three-dimensional direction. The drive plate 41 is provided with a first drive block 43, and the first drive block 43 is provided with a vacuum suction port.

[0043] Specifically, during the test line detection, the first three-dimensional driving mechanism 42 drives the first driving block 43 to move below the product test line, attracts the product test line, and pulls the product test line downward and backward first, and then drives the product test line forward to the test line detection mechanism 5.

[0044] The above method ensures the stability of the test lead during movement, avoiding detection errors caused by shaking or positional shifts. Simultaneously, the vacuum suction port design enhances the adsorption capacity of the test lead, making it more precise and reliable during pulling and forward feeding. Furthermore, the retraction of the product test lead allows space for the forward movement of the test lead detection mechanism 5, enabling the product test lead to be accurately inserted into the mechanism.

[0045] In this embodiment, the test line detection mechanism 5 includes a drive frame 51, a first lower abutment block 52 is provided on the drive frame 51, a first lower pressing block 53 is provided above the first lower abutment block 52, a first needle membrane for contacting the test line is provided at the bottom of the first lower pressing block 53, and also includes a first drive mechanism 54 mounted on the drive frame 51 for driving the first lower pressing block 53 to perform a downward pressing movement, and a second drive mechanism 55 for driving the drive frame 51 to perform a horizontal movement.

[0046] During the specific testing, the second drive mechanism 55 drives the drive frame 51 to move forward, and the product's test line is sent to the first lower contact block 52. The first drive mechanism 54 drives the first lower pressure block 53 to press down, and the product's test line contacts the first needle membrane to perform an electrical test on the test line.

[0047] The above-described method effectively ensures the contact stability between the test lead and the first needle membrane, thereby improving the accuracy of the power-on detection. Simultaneously, the horizontal movement design of the drive frame 51 allows the test lead to be precisely positioned at the first lower abutment block 52, avoiding detection failures due to positional deviations.

[0048] In this embodiment, a support plate 61 is also provided below the electrical testing fixture 2. The support plate 61 is located below the product test line. A third drive mechanism 62 for driving the support plate 61 to move horizontally is provided on one side of the support plate 61.

[0049] Specifically, when the product is placed on the electrical testing fixture 2, the product test line falls on the support plate 61, and the end of the product test line extends out of the support plate 61. Then, after the first drive block 43 attracts the end of the test line, the third drive mechanism 62 drives the support plate 61 to retract, so that the first drive block 43 can drive the test line to perform subsequent pull-down and retraction movements.

[0050] In this structure, the support plate 61 can support the test line and prevent it from drooping, thus preventing the first drive block 43 from accurately adsorbing the test line. At the same time, after the first drive block 43 adsorbs the test line, the support plate 61 retracts. The retracted support plate 61 will not interfere with the subsequent movement of the test line, thus ensuring that the test line remains stable and accurate during movement.

[0051] In this embodiment, the capacitance testing mechanism 3 includes an XY axis driving mechanism 31, a first rotary driving mechanism 32 is provided at the driving end of the XY axis driving mechanism 31, a mounting block 33 is provided at the driving end of the first rotary driving mechanism 32, a second lower abutment block 34 is provided on the mounting block 33, a second lower pressing block 35 is provided above the second lower abutment block 34, a second needle film for contacting the product capacitor is provided on the second lower abutment block 34, and a fourth driving mechanism 36 is also provided on the mounting block 33 for driving the second lower pressing block 35 to perform a downward pressing movement.

[0052] Specifically, during capacitance testing, the second lower contact block 34 is first precisely positioned below the product capacitor through the coordinated movement of the XY-axis drive mechanism 31 and the first rotary drive mechanism 32. Subsequently, the fourth drive mechanism 36 drives the second lower pressure block 35 downwards, ensuring close contact between the second needle film and the product capacitor, thus completing the capacitance value detection. During this process, the coordinated operation of the XY-axis drive mechanism 31 and the first rotary drive mechanism 32 ensures that the second lower contact block 34 accurately reaches the designated position, avoiding errors caused by manual adjustment and significantly improving testing efficiency and accuracy.

[0053] In this embodiment, a detection camera for detecting the position of the capacitor is provided above the capacitor testing structure; when the detection camera is positioned at the product capacitor position, the XY axis drive mechanism 31 and the first rotation drive mechanism 32 cooperate to move, driving the second lower abutment block 34 to move below the product capacitor.

[0054] Specifically, the detection camera accurately captures the position information of the product capacitor using image recognition technology and transmits this information to the control system. Based on the received data, the control system automatically adjusts the motion parameters of the XY-axis drive mechanism 31 and the first rotary drive mechanism 32 to ensure that the second lower abutment block 34 is accurately aligned directly below the product capacitor. This automated positioning method not only reduces manual intervention but also significantly improves positioning accuracy and testing consistency.

[0055] In this embodiment, the electrical testing fixture 2 is provided with a telescopic pressure plate 37, and also includes a second rotary drive mechanism 38 for driving the telescopic pressure plate 37 to rotate. A lower abutment plate 39 is provided on one side of the electrical testing fixture 2, and a spring is provided between the lower abutment plate 39 and the electrical testing fixture 2.

[0056] When the telescopic pressure plate 37 rotates to a horizontal position, the telescopic pressure plate moves onto the lower abutment plate 39.

[0057] In actual operation, the second rotary drive mechanism 38 drives the telescopic pressure plate 37 to perform a rotating and smoothing motion above the product capacitor. The capacitor is pulled flat by the telescopic pressure plate 37 and the lower abutment plate 39. The lower abutment plate 39 is pressed inward by the second lower abutment block 34, and the product capacitor extends out of the lower abutment plate 39 and falls on the second lower abutment block 34.

[0058] In this structure, the use of the telescopic pressure plate 37 and the lower abutment plate 39 together can achieve the smoothing operation of the product capacitor, so that the product capacitor can be accurately fed into the capacitor testing mechanism 3.

[0059] In this embodiment, the electrical testing fixture 2 is provided with a plurality of suction cup structures 21 for holding the product.

[0060] Specifically, when the product is placed on the electrical testing fixture 2, the suction cup structure 21 will automatically activate the adsorption function to ensure that the product is quickly fixed in place, thereby preventing the product from shifting or shaking during the test, thus ensuring the stability and accuracy of the test.

[0061] This invention also discloses a method for testing the energization of capacitors and buttons, using the aforementioned capacitor and button energization testing equipment, characterized by comprising the following steps:

[0062] Load the product onto electrical testing fixture 2 and perform capacitance and power-on tests on the product;

[0063] During capacitance testing, the second rotary drive mechanism 38 drives the telescopic pressure plate 37 to rotate and flatten above the product capacitor. The capacitor is flattened under the action of the telescopic pressure plate 37 and the lower abutment plate 39. Then, the detection camera detects the position of the capacitor. The XY axis drive mechanism 31 and the first rotary drive mechanism 32 work together to drive the second lower abutment block 34 to move below the product capacitor. At this time, the lower abutment plate 39 is pressed inward under the action of the second lower abutment block 34. The product capacitor extends out of the lower abutment plate 39 and falls on the second lower abutment block 34. The fourth drive mechanism 36 drives the second lower pressure block 35 to press down, so that the product capacitor is in close contact with the second needle film, and tests whether the product capacitor is within the specified range.

[0064] During the power-on test, the first three-dimensional drive mechanism 42 drives the first drive block 43 to move below the product test line, attracts the product test line, and pulls the product test line downward and backward. The second drive mechanism 55 drives the drive frame 51 to move forward, and the first three-dimensional drive mechanism 42 drives the first drive block 43 to move forward, so that the test line is sent to the first lower abutment block 52. The first drive mechanism 54 drives the first lower pressure block 53 to press down, and the product test line contacts the first needle membrane to perform a power-on test on the test line. After successful power-on, the button on the product is pressed, and the screen is observed to realize the button test.

[0065] In this method, the cooperation between the wire feeding mechanism 4 and the test wire detection mechanism 5 ensures that the test wires at the bottom of the product can be accurately inserted into the test wire detection mechanism 5 for power-on testing.

[0066] Meanwhile, the XY axis drive mechanism 31 and the rotation mechanism in the capacitance testing mechanism 3 can drive the second lower abutment block 34 and the second lower pressure block 35 to move actively to the product capacitor, so that there is no need to control the product movement during testing, which simplifies the structure and makes the overall operation more convenient.

[0067] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
