Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board testing, and in particular relates to a circuit board side-insertion testing module and a testing device. Background Art

[0002] In circuit board testing, it is usually necessary to burn and read the pins on the circuit board to evaluate its performance and various functions. For most circuit boards, the pins are mainly located on the front of the circuit board. The upper mold assembly of the test device is pressed down to make the test probe contact the pins to complete the test. However, for some specially designed circuit boards, especially those with side-plug connectors, the pins are located on the side of the circuit board, which brings additional challenges to testing.

[0003] Traditional testing methods often require two tests to be performed using two independent test devices: first use one device to test the pin points on the front of the circuit board, and then use another device to test the pin points on the side. This method is not only inefficient, increasing test time and cost, but also requires additional equipment space and maintenance costs.

[0004] To overcome these limitations, some test devices integrate side pin point testing functions. However, these devices usually use complex mechanical structures, such as double sets of drive mechanisms, where the first set of drive mechanisms is used for testing the front pin points, and the second set of drive mechanisms is used for testing the side pin points. This design not only increases the complexity and production cost of the equipment, but may also increase the difficulty of maintenance and reduce the reliability and stability of the test device.

[0005] Therefore, there is an urgent need for a circuit board side insertion test module and a test device that can meet the needs of circuit board side insertion testing, improve test efficiency and reduce test costs. Utility Model Content

[0006] The purpose of the utility model is to address the deficiencies in the prior art and provide a circuit board side-insertion test module and a test device, which can realize the test of side pin points through a simple mechanical structure while the upper mold assembly is pressed down, thereby simplifying the test process, improving test efficiency, and reducing production costs and maintenance difficulties.

[0011] An upper mold assembly is arranged above the carrier plate, and the upper mold assembly moves longitudinally to approach or move away from the carrier plate. A pressing piece is provided on the upper mold assembly. When the pressing piece presses down the slider through the reversing inclined surface, the slider pushes the probe to abut against the side needle point of the circuit board to be tested.

[0012] Furthermore, the slider is made of insulating material, and the probe is electrically connected to the carrier.

[0013] Furthermore, a roller is provided at one end of the slider close to the pressing member, and a first inclined surface is provided at the bottom end of the pressing member. When the pressing member is pressed downward, the first inclined surface contacts the roller to push the slider to move.

[0014] Furthermore, a first limiting groove is arranged in the slider seat corresponding to the length direction of the slide rail, and a first limiting column is arranged on the slider, and the first limiting column can be movably installed in the first limiting groove.

[0015] Optionally, the slider is made of a conductive material and is electrically connected to the probe, and the lower pressing piece is made of a conductive material and is electrically connected to the upper mold assembly.

[0016] Furthermore, the pressing member is a copper column, and the slider is provided with a second inclined surface at one end close to the pressing member. When the pressing member is pressed down, the bottom end of the pressing member contacts the second inclined surface and forms an electrical connection with the slider, thereby pushing the slider to move.

[0036] See attached Figure 1 To Attachment Figure 6 , the figure shows a specific embodiment of a circuit board side-insertion test module and a test device provided by the utility model. Example

[0037] See attached Figure 1 This embodiment provides a circuit board side plug-in test module, including:

[0038] A carrier board 1, on which a test position 110 is provided, and the test position 110 is used to place a circuit board 7 to be tested;

[0039] A side plug assembly 2 is disposed on the carrier 1 and close to the test position 110, and the side plug assembly 2 includes a slider seat 210, a slide rail 211 is formed on the slider seat 210, a slider 220 is movably mounted on the slide rail 211, a probe 230 is mounted on one end of the slider 220 close to the test position 110, and an elastic member 240 is disposed between the slider 220 and the slider seat 210;

[0040] An upper mold assembly 3 is disposed above the carrier board 1, and the upper mold assembly 3 moves longitudinally to approach or move away from the carrier board 1. A lower pressing piece 310 is provided on the upper mold assembly 3. When the lower pressing piece 310 presses down the slider 220 through the reversing inclined surface, the slider 220 pushes the probe 230 to abut against the side needle point of the circuit board 7 to be tested.

[0041] See attached Figure 2 and attached Figure 3 In this embodiment, the slider 220 is made of insulating material, and the probe 230 is electrically connected to the carrier 1. In the embodiment, when testing the circuit board 7 to be tested, the upper mold assembly 3 is pressed down, and the upper mold assembly 3 performs a contact test on the pin point on the front of the circuit board 7 to be tested, and the lower pressing member 310 contacts the slider 220. The contact surface of the slider 220 or the lower pressing member 310 can be provided with a reversing inclined surface. When the lower pressing member 310 is pressed down, the slider 220 moves laterally in the slide rail 211 in the slider seat 210, and at the same time pushes the probe 230 to move into the side plug connector of the circuit board 7 to be tested, and abuts against the pin point of the side plug connector for testing.

[0042] See attached Figure 2 and attached Figure 3 In this embodiment, a roller 221 is provided at one end of the slider 220 close to the pressing member 310, and a first inclined surface 311 is provided at the bottom end of the pressing member 310. When the pressing member 310 is pressed downward, the first inclined surface 311 contacts the roller 221 to push the slider 220 to move. In the embodiment, when the upper mold assembly 3 moves downward to test the circuit board 7 to be tested, the pressing member 310 moves downward, the first inclined surface 311 of the pressing member 310 contacts the roller 221, and the roller 221 rolls, and the first inclined surface 311 pushes the roller 221 and the slider 220.

[0043] See attached Figure 2 and attached Figure 3 In this embodiment, a first limiting groove 212 is provided in the slider seat 210 corresponding to the length direction of the slide rail 211, and a first limiting column 223 is provided on the slider 220, and the first limiting column 223 can be movably installed in the first limiting groove 212. In the embodiment, when the slider 220 moves in the slider seat 210, the first limiting column 223 on the slider 220 also moves in the first limiting groove 212 of the slider seat 210. The length limitation of the first limiting groove 212 prevents the slider 220 from moving too much, thereby preventing the side plug connector of the circuit board 7 to be tested or the probe 230 from being damaged. Example

[0044] See attached Figure 1 This embodiment provides another circuit board side plug-in test module, including:

[0045] A carrier board 1, on which a test position 110 is provided, and the test position 110 is used to place a circuit board 7 to be tested;

[0046] A side plug assembly 2 is disposed on the carrier 1 and close to the test position 110, and the side plug assembly 2 includes a slider seat 210, a slide rail 211 is formed on the slider seat 210, a slider 220 is movably mounted on the slide rail 211, a probe 230 is mounted on one end of the slider 220 close to the test position 110, and an elastic member 240 is disposed between the slider 220 and the slider seat 210;

[0047] An upper mold assembly 3 is disposed above the carrier board 1, and the upper mold assembly 3 moves longitudinally to approach or move away from the carrier board 1. A lower pressing piece 310 is provided on the upper mold assembly 3. When the lower pressing piece 310 presses down the slider 220 through the reversing inclined surface, the slider 220 pushes the probe 230 to abut against the side needle point of the circuit board 7 to be tested.

[0048] See attached Figure 4 In this embodiment, the slider 220 is made of a conductive material and is in electrical communication with the probe 230, and the lower pressing member 310 is made of a conductive material and is electrically connected to the upper mold assembly 3. In the embodiment, when testing the circuit board 7 to be tested, the upper mold assembly 3 is pressed down, and the upper mold assembly 3 performs a contact test on the pin points on the front of the circuit board 7 to be tested, and the lower pressing member 310 contacts and conducts with the slider 220, while the slider 220 is in electrical communication with the probe 230. When the lower pressing member 310 is pressed down, the slider 220 moves laterally in the slide rail 211 in the slider seat 210, and at the same time pushes the probe 230 to move into the side plug connector of the circuit board 7 to be tested, and abuts against the pin point of the side plug connector. The upper mold assembly 3 is electrically connected to the pin point of the side plug connector of the circuit board 7 to be tested through the lower pressing member 310, the slider 220, and the probe 230, so as to perform the test.

[0049] See attached Figure 4In this embodiment, the pressing member 310 is a copper column, and the end of the slider 220 close to the pressing member 310 is provided with a second inclined surface 222. When the pressing member 310 is pressed down, the bottom end of the pressing member 310 contacts the second inclined surface 222 and forms an electrical connection with the slider 220, and pushes the slider 220 to move. In the embodiment, the bottom end of the pressing member 310 is set as a round head, and forms an electrical connection when contacting the second inclined surface 222 of the slider 220. If the pressing member 310 is pressed down continuously, the slider 220 is pushed to move in the slider seat 210 while maintaining the electrical connection.

[0050] See attached Figure 4 In this embodiment, the slider 220 is provided with a second limiting groove 224 corresponding to the length direction of the slide rail 211, and the slider seat 210 is provided with a second limiting column 213, which can be movably installed in the second limiting groove 224. In the embodiment, when the slider 220 moves in the slider seat 210, the second limiting column 213 on the slider seat 210 also moves in the second limiting groove 224 of the slider 220. The length limit of the second limiting groove 224 prevents the slider 220 from moving too much, thereby preventing the side plug connector of the circuit board 7 to be tested or the probe 230 from being damaged. Example

[0051] See attached Figure 5 and attached Figure 6 This embodiment provides a test device, including the circuit board side plug-in test module of embodiment 1, and further including:

[0052] A body 4, in which a control component 410 for controlling the test process is disposed, and the carrier board 1 is mounted on the body 4;

[0053] A bracket 5 is mounted on the machine body 4 , a longitudinal movement assembly 6 is provided on the bracket 5 , and the upper mold assembly 3 is mounted on the longitudinal movement assembly 6 .

[0054] See attached Figure 5 and attached Figure 6 In this embodiment, the longitudinal movement component 6 enables the upper mold component 3 to move longitudinally above the carrier 1, so as to realize the front pin point test and the side pin point test of the circuit board 7 to be tested. The control component 410 includes an operating button arranged on the side of the body 4 to control the switch of the device.

[0055] See attached Figure 5 and attached Figure 6 In this embodiment, the longitudinal movement assembly 6 includes an operating handle 610 and longitudinal movement rails 620 connected to both ends of the upper mold assembly 3, which are used to drive the upper mold assembly 3 to move longitudinally. In the embodiment, the operating handle 610 is connected to the upper mold assembly 3, and when the operating handle 610 is moved, the upper mold assembly 3 moves up and down along the longitudinal movement rails 620.

[0056] See attached Figure 5 and attached Figure 6 In this embodiment, a transverse track 420 is provided on the machine body, the carrier 1 is mounted on the transverse track 420, and an anti-fool rod 120 cooperating with the upper mold assembly 3 is provided at the rear of the carrier 1. In the embodiment, the carrier 1 can move forward and backward in a drawer-like manner on the transverse track 420, and the circuit board 7 to be tested can be replaced when the carrier 1 is pulled out, and the upper mold assembly 3 can be pressed down for testing after the carrier 1 is pushed in. In the embodiment, after the carrier 1 is pulled out, the anti-fool rod 120 at the rear of the carrier 1 corresponds to the upper mold assembly 3. At this time, if the upper mold assembly 3 is pressed down, the upper mold assembly 3 will be blocked by the anti-fool rod 120, so that it cannot be pressed down further. When the carrier 1 is pushed in, the anti-fool rod 120 at the rear of the carrier 1 will be staggered with the upper mold assembly 3. At this time, the upper mold assembly 3 can be pressed down normally for testing, avoiding damage to the device caused by accidentally pressing down the upper mold assembly 3 after the carrier 1 is pulled out.

[0057] In summary, the present embodiment provides a circuit board side insertion test module and a test device. By arranging a slider 220 on the carrier 1 and arranging a probe 230 on the slider 220, when the upper mold assembly 3 is pressed down, the probe 230 can be pushed to the side needle point of the circuit board 7 to be tested through the reversing inclined surface, so as to realize the test of the side needle point with a simple mechanical structure, thereby simplifying the test process; by arranging a roller 221, the wear between the pressing member 310 and the slider 220 can be avoided; by arranging a first limiting groove 212 and a first limiting column 223, the moving distance of the slider 220 can be limited, thereby avoiding damage to the circuit board 7 to be tested; by arranging a transverse track 420, it is convenient to pull out the carrier 1 to replace the circuit board 7 to be tested; by arranging an anti-fool rod 120, it is avoided that the upper mold assembly 3 is accidentally pressed down after the carrier 1 is pulled out, thereby avoiding damage to the device; the present embodiment can realize the test of the side needle point through a simple mechanical structure while the upper mold assembly 3 is pressed down, thereby simplifying the test process, improving the test efficiency, and reducing the production cost and maintenance difficulty.
