The following problems exist in this technical solution:

[0004] In the existing method, when the PCB board is tested, the PCB board is transported on the material receiving machine box, and it is inconvenient to clamp and fix the PCB board, resulting in the PCB board being easily shaken and displaced during the test of the test machine, and it is also impossible to test both sides of the PCB board, which reduces the test effect;

[0005] In view of the above problems, the utility model document proposes a material changing mechanism for a flying probe tester. Utility Model Content

[0006] The utility model provides a material changing mechanism for a flying probe tester, which solves the problem in the prior art that when a PCB board is tested, the PCB board is transported on a material receiving box and it is inconvenient to clamp and fix the PCB board, resulting in the PCB board being prone to shaking and shifting during the test of the tester, and at the same time, it is impossible to test both sides of the PCB board, thereby reducing the disadvantage of the test effect.

[0007] The utility model provides the following technical solutions:

[0008] The material changing mechanism of the flying probe tester includes:

[0009] A material changing platform, wherein a mounting groove is provided on the top of the material changing platform, a first electric push rod is fixedly installed on the bottom side of the inner wall of the mounting groove, and a pushing frame for lifting the PCB is fixedly installed on the output end of the first electric push rod;

[0010] A clamping mechanism, which is arranged on the top of the material changing table and is used to clamp and fix the PCB to be tested;

[0011] The material receiving mechanism is arranged on one side of the material changing table and is used for receiving the tested PCB boards.

[0012] In a possible design, the clamping mechanism includes two sliding frames, both of which are fixedly arranged on the top of the material exchange table, and both of the sliding frames are slidably connected to the inside of the two sliding frames. A support plate is fixedly arranged on the top side of each of the sliders, and a motor is fixedly installed on one side of one of the support plates, and the output end of the motor passes through one side of one of the support plates and extends to the other side of one of the support plates.

[0013] In a possible design, the output end of the motor is fixed with forward and reverse screws through a coupling, the outer walls of the forward and reverse screws are threadedly connected to two clamping blocks, one side of each of the clamping blocks is provided with a clamping groove for plugging in a PCB board, one side of the inner wall of the clamping groove is provided with a fitting pad, a sliding rod is fixed between the two support plates, and the interior of each of the clamping blocks is provided with a sliding hole that is slidably connected to the outer wall of the sliding rod.

[0014] In a possible design, a support frame is fixedly installed on one side of the material exchange table, a hydraulic cylinder is fixedly installed on the top of the support frame, a push plate is fixedly provided on the output end of the hydraulic cylinder, and one side of the push plate is fixed to one side of two support plates.

[0015] In a possible design, the material receiving mechanism includes two support frames, both of which are fixedly mounted on one side of the material changing table, and a material receiving frame for limiting and accommodating the tested PCB boards is fixedly mounted between the two support frames, and damping buffers are symmetrically fixedly arranged on the bottom side of the inner wall of the material receiving frame, and buffer plates are fixedly arranged on the top of the four damping buffers.

[0016] In a possible design, a material receiving frame for carrying the PCB board is fixedly provided on one side of the material changing table, and a limiting placement frame for limiting the placement of the PCB board is fixedly provided on the top side of the material receiving frame.

[0017] In a possible design, a second electric push rod is fixedly installed on one side of the material changing table, and a pushing frame for pushing the PCB board on the material receiving frame is fixedly provided on the output end of the second electric push rod. A feeding slot for the PCB board to pass through is opened on one side of the material changing table, and the feeding slot is connected to the mounting slot.

[0018] In the present application, when in use, the operator first places the PCB board to be tested neatly in the limit placement frame in the material receiving frame. The limit placement frame can accommodate more PCB boards to ensure that the PCB boards can be stably placed. Then, the second electric push rod is turned on and started by the controller, and its output end pushes the push frame to move forward. The push frame can push the PCB board at the bottom of the material receiving frame into the corresponding push frame through the feed slot. The push frame can limit the PCB board. After the PCB board is pushed into the push frame, the first electric push rod is turned on and started. Its output end pushes the push frame to rise, and then the PCB board in the push frame can be lifted to a certain height, so that the PCB board can rise to a suitable test height for later testing operations.

[0019] After the PCB board reaches a certain height, the motor is turned on by the controller to start, and the motor drives the forward and reverse screws to rotate through the coupling. Since the forward and reverse screws are threadedly connected to the two clamping blocks, and the clamping blocks slide on the slide rods through the sliding holes, the two clamping blocks can be driven to move relative to or away from each other. When the clamping blocks move relatively, the clamping groove can be used to clamp the PCB board to a limited position. At the same time, the fitting pad in the clamping groove can firmly clamp the PCB board in the center position to ensure that the PCB board will not move during the test process, thereby achieving the effect of clamping and fixing, avoiding the phenomenon of shaking and displacement of the PCB board during the later test of the test machine, and at the same time, it is also conducive to the double-sided test of the PCB board, which improves the test effect. After the PCB board is fixed, the main test device of the flying probe tester can be used to start testing it, which is easy to use;

[0020] After the test is completed, the hydraulic cylinder on the support frame is turned on to operate, and the hydraulic cylinder can drive the push plate fixed at the output end to move, and the push plate will push the support plate and the PCB board to move. At the same time, the sliding block fixed on the bottom side of the support plate will slide in the corresponding sliding frame, which is conducive to playing the role of sliding limit and enhancing firmness. Then, the PCB board can be pushed to the top of the material receiving mechanism for easy material discharge, which improves convenience. At the same time, the motor of the clamping mechanism rotates in the opposite direction, and the clamping blocks are driven to move in opposite directions through the forward and reverse screws to release the PCB board. The PCB board falls and then falls into the corresponding material receiving frame. The tested PCB board can be limited and accommodated by the material receiving frame, so as to facilitate the product to be taken, which improves convenience. The material receiving frame can provide buffering for the PCB board through the damping buffer and the buffer plate, ensuring that the PCB board falls smoothly into the material receiving frame to avoid damage and improve the use effect. Therefore, repeating the above steps can be carried out for the next round of testing, so as to achieve the purpose of material replacement and improve the test efficiency.

[0021] In the utility model, the material changing mechanism of the flying probe tester can firmly clamp the PCB board at the center position through the clamping mechanism, ensuring that the PCB board will not move during the test process, thereby achieving the effect of clamping and fixing;

[0022] In the utility model, the material changing mechanism of the flying probe tester can limit and accommodate the tested PCB board through the material receiving mechanism, so as to facilitate the product to be taken, thereby improving the convenience;

[0023] In the utility model, the PCB board can be firmly clamped at the center position to ensure that the PCB board will not move during the test process, thereby achieving the effect of clamping and fixing, avoiding the phenomenon of shaking and shifting of the PCB board during the later test of the test machine, and at the same time facilitating the double-sided test of the PCB board, thereby improving the test effect.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Example 1

[0033] Please refer to Figure 1-Figure 5 , material changing mechanism, including:

[0034] A material changing platform 1 is provided with a mounting groove 2 on the top of the material changing platform 1, a first electric push rod 3 is fixedly installed on the bottom side of the inner wall of the mounting groove 2, a push frame 4 for lifting the PCB board is fixedly installed on the output end of the first electric push rod 3, a second electric push rod 8 is fixedly installed on one side of the material changing platform 1, a push frame 7 for pushing the PCB board on the material receiving frame 6 is fixedly arranged on the output end of the second electric push rod 8, a feeding slot 5 for the PCB board to pass through is provided on one side of the material changing platform 1, the feeding slot 5 is connected to the mounting groove 2, and the second electric push rod 8 is opened. The electric push rod 8 is started, and its output end pushes the push frame 7 to move forward. The push frame 7 can push the PCB board at the bottom of the material frame 6 into the corresponding push frame 4 through the feed slot 5. The push frame 4 can limit the PCB board. After the PCB board is pushed into the push frame 4, the first electric push rod 3 is opened and started, and its output end pushes the push frame 4 to rise, and then the PCB board in the push frame 4 can be lifted to a certain height, so that the PCB board can rise to a suitable test height for later testing operations.

[0035] A clamping mechanism is arranged on the top of the material changing table 1 to clamp and fix the PCB board to be tested. The clamping mechanism includes two sliding frames 10. The two sliding frames 10 are fixedly arranged on the top of the material changing table 1. The insides of the two sliding frames are slidably connected with sliders 11. A support plate 12 is fixedly arranged on the top side of each slider 11. A motor 13 is fixedly installed on one side of one of the support plates 12. The output end of the motor 13 passes through one side of one of the support plates 12 and extends to the other side of one of the support plates 12. A support frame 22 is fixedly installed on one side of the material changing table 1. A hydraulic cylinder 23 is fixedly installed on the top of the support frame 22. A push plate 24 is fixedly arranged on the output end of the hydraulic cylinder 23. One side of the push plate 24 is fixed to one side of the two support plates 12.

[0036] The hydraulic cylinder 23 on the support frame 22 is turned on and operated. The hydraulic cylinder 23 can drive the push plate 24 fixed at the output end to move. The push plate 24 will push the support plate 12 and the PCB board to move. At the same time, the slider 11 fixed on the bottom side of the support plate 12 will slide in the corresponding slide frame 10, which is beneficial to play the role of sliding limit and enhance the firmness. Then the PCB board can be pushed to the top of the material receiving mechanism for easy material discharge, thereby improving the convenience.

[0037] The output end of the motor 13 is fixedly provided with a forward and reverse screw 14 through a coupling, and the outer wall of the forward and reverse screw 14 is threadedly connected to two clamping blocks 15, and one side of each clamping block 15 is provided with a clamping groove 16 for plugging in the PCB board, and a fitting pad is provided on one side of the inner wall of the clamping groove 16. A sliding rod 17 is fixedly arranged between the two support plates 12, and the interior of each clamping block 15 is provided with a sliding hole that is slidably connected to the outer wall of the sliding rod 17. When the motor 13 is turned on and started, the motor 13 drives the forward and reverse screws 14 to rotate through the coupling. Since the forward and reverse screws 14 are threadedly connected to the two clamping blocks 15, and the clamping blocks 15 slide on the sliding rod 17 through the sliding hole, the two clamping blocks 15 can be driven to move relative to or away from each other. When the clamping blocks 15 move relatively, the clamping groove 16 can be used to clamp the PCB board to a limit position, and at the same time, the fitting pad in the clamping groove 16 can firmly clamp the PCB board in the center position to ensure that the PCB board will not move during the test process, thereby achieving the effect of clamping and fixing.

[0038] The material receiving mechanism is arranged on one side of the material changing platform 1 for receiving the tested PCB boards. The material receiving mechanism includes two support frames 18. The two support frames 18 are fixedly installed on one side of the material changing platform 1. A material receiving frame 19 for limiting and accommodating the tested PCB boards is fixedly installed between the two support frames 18. Damping buffers 20 are fixedly arranged on the bottom side of the inner wall of the material receiving frame 19 in pairs, and buffer plates 21 are fixedly arranged on the tops of the four damping buffers 20.

[0039] The motor 13 of the clamping mechanism rotates in the opposite direction, and drives the clamping block 15 to move in opposite directions through the forward and reverse screws 14, thereby releasing the PCB board, and the PCB board falls down and then falls into the corresponding receiving frame 19. The tested PCB board can be limited and accommodated by the receiving frame 19 to facilitate the product to be taken, thereby improving the convenience. The receiving frame 19 can provide buffering for the PCB board through the damping buffer 20 and the buffer plate 21, ensuring that the PCB board falls smoothly into the receiving frame 19 to avoid damage.

[0040] The present application can be used in the field of material changing devices, and can also be used in other fields applicable to the present application.

The PCB board to be tested is neatly placed in the limit placement frame 9 in the material receiving frame 6. The limit placement frame 9 can accommodate more PCB boards to ensure that the PCB boards can be placed stably.
