Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, specifically an electronic component testing device. Background Technology

[0002] Connectors, circuit boards, sensors, and other electronic components are core building blocks of electronic devices. Their performance and reliability directly determine the overall operation of the equipment. Therefore, they must be tested: on the one hand, to identify potential defects in the production process, such as poor contact, abnormal signal transmission, and voltage mismatch, to prevent equipment from crashing, malfunctioning, or even damaging other components after installation; on the other hand, to verify whether the components meet safety and industry standards, to prevent safety hazards such as electric shock and fire caused by poor insulation, overheating, etc.

[0003] Chinese Patent Publication No. CN221405934U discloses an electronic component testing fixture, belonging to the field of testing fixtures. It includes a body with a bracket fixedly mounted on it. A cylinder is fixedly mounted on the bracket, and a test frame is movably mounted below the cylinder. A worktable is fixedly mounted on the body below the test frame. A button is movably mounted on the side of the worktable. A fixing mechanism is movably mounted on the worktable. Through this fixing mechanism, rubber fulcrums support the printed circuit board. The rubber fulcrums are elastic, minimizing damage to the printed circuit board. The rotating screw moves the first and second air tubes, adjusting the position of the rubber adsorption rings. The rubber adsorption rings adsorb and fix the printed circuit board. The use of soft material to fix the hard circuit board prevents scratches and bending, facilitating workpiece positioning for testing. It also avoids scratches and damage to the printed circuit board from debris remaining on the worktable, making it more convenient to use.

[0004] In existing technologies, the testing space is relatively fixed. When the size of the test piece is different, the equipment needs to be repeatedly disassembled and modified, which reduces work efficiency.

[0005] In summary, this utility model provides an electronic component testing device to solve the above-mentioned problems. Utility Model Content

[0006] This invention provides an electronic component testing device that solves the problem of existing technologies being unable to quickly adapt to test pieces of different sizes by flexibly adjusting the testing space.

[0007] The specific technical solution of this utility model is as follows:

[0008] An electronic component testing device includes a test piece, a test base detachably connected to the lower part of the test piece, a transmission belt disposed below the test base, a transmission rod being driven to the inner side of the transmission belt, a drive belt being driven to the side of the transmission rod, a drive motor being disposed on the side of the drive belt away from the transmission rod, the output end of the drive motor being driven to the drive belt, a support frame being disposed on the side of the transmission belt, a drive cylinder being disposed below the support frame, the output end of the drive cylinder being fixedly connected to the bottom of the support frame, a sliding clamp being disposed on the side of the test piece, a guide platform being slidably connected below the sliding clamp, a drive electric cylinder being disposed above the guide platform, and the output end of the drive electric cylinder being fixedly connected to the sliding clamp.

[0009] In this invention, the test piece is the electronic component to be tested, which is the object of all testing actions; the test base is used to fix and position the test piece, while ensuring the stability of the test piece's position during the test; the transmission belt is used to carry and transport the test base and the test piece; the transmission rod acts as the hub for power transmission; the drive belt is used to transmit the power of the drive motor to the transmission rod; the support frame, as the overall support component, is equipped with multiple rotating shafts for supporting the transmission belt and is also rotatably connected to the transmission rod, and can move up and down under the drive of the drive cylinder, thereby changing the height of the test base to accommodate test pieces of different sizes. Furthermore, the drive belt and transmission belt can be made of materials such as rubber, possessing a certain deformation capacity, so that even after the height of the support frame changes, the device can still control the test base to move horizontally, further expanding the device's applicability; the sliding clamp is used to install the probe; the guide table restricts the movement direction of the sliding clamp; the drive cylinder drives the sliding clamp to slide along the guide table, realizing the docking or separation of the sliding clamp and the test piece, completing the side testing action.

[0011] In this invention, the balance blocks and balance plates form a cross-shaped hinge structure. The two balance blocks at the bottom are fixed to other components below or the ground. When the support frame moves up and down under the drive of the cylinder, the balance plates rotate in a cross manner to achieve synchronous expansion or contraction. By utilizing the synergistic effect of the multi-node rotation connection, the support frame is provided with lateral stability support, effectively suppressing any tilting, swaying or offset that may occur during the lifting and lowering of the support frame.

[0012] In a preferred embodiment, a test rod is provided above the test piece, a lifting slide is provided on the side of the test rod, and a mounting plate is fixedly connected to the side of the lifting slide.

[0014] In a preferred embodiment, a probe is detachably connected to the side of the sliding clamp.

[0015] In this invention, the probe is used to contact the side terminals on the side of the test piece to conduct electrical signals and complete the side electrical performance test.

[0016] In a preferred embodiment, a press button is provided on the top of the test piece.

[0017] In this invention, the pressing button serves as the functional part to be tested on the test piece, and is used to cooperate with the pressing action of the test rod.

[0018] In a preferred embodiment, the test piece is provided with side terminals on its side.

[0019] In this invention, the side terminal serves as an electrical connection point on the test piece, used to contact the probe and provide a contact point for testing the electrical performance of the side.

[0020] In a preferred embodiment, a driven belt is provided below the guide platform, and the inner side of the driven belt is connected to the transmission rod.

[0021] In this invention, the driven belt causes the guide stage and the test base to move synchronously in the horizontal direction, keeping the probe aligned with the side terminal, thus eliminating the need for repeated calibration of the probe position.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model achieves adaptive adjustment of the test load height through the synergistic effect of rigid support and linear drive, and forms a compatible testing mechanism for multi-size test pieces by combining elastic transmission. This avoids the problem of equipment disassembly and modification due to fixed test space in the prior art, simplifies the changeover process for multi-specification test pieces, and improves the device's adaptability and testing efficiency for electronic components of different sizes.

[0024] 2. This utility model uses the motion coupling design of the transmission system to keep the test piece and the test execution component moving horizontally synchronously, and enhances the stability of the support system through the anti-interference characteristics of the cross hinge structure.

[0031] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0032] like Figure 1-5As shown, this utility model provides an electronic component testing device, including a test piece 1. A test base 2 is detachably connected to the lower part of the test piece 1. A transmission belt 3 is disposed below the test base 2. A transmission rod 4 is driven to the inner side of the transmission belt 3. A drive belt 5 is driven to the side of the transmission rod 4. A drive motor 6 is disposed on the side of the drive belt 5 away from the transmission rod 4. The output end of the drive motor 6 is driven to the drive belt 5. A support frame 7 is disposed on the side of the transmission belt 3. A drive cylinder 8 is disposed below the support frame 7. The output end of the drive cylinder 8 is fixedly connected to the bottom of the support frame 7. A sliding clamp 15 is disposed on the side of the test piece 1. A guide platform 16 is slidably connected below the sliding clamp 15. A drive electric cylinder 17 is disposed above the guide platform 16. The output end of the drive electric cylinder 17 is fixedly connected to the sliding clamp 15.

[0033] A first balance block 9 is fixedly connected to the lower side of one side of the support frame 7. A second balance block 10 is disposed below the first balance block 9. A first balance plate 11 is rotatably connected to the side of the first balance block 9. A fourth balance block 14 is rotatably connected to the side of the first balance plate 11 away from the first balance block 9. A third balance block 13 is disposed above the fourth balance block 14. A second balance plate 12 is rotatably connected to the side of the second balance block 10. The side of the second balance plate 12 away from the second balance block 10 is rotatably connected to the third balance block 13. The middle part of the first balance plate 11 is rotatably connected to the middle part of the second balance plate 12.

[0034] A test rod 18 is provided on the top of the test piece 1, and a lifting slide 19 is provided on the side of the test rod 18. A mounting plate 20 is fixedly connected to the side of the lifting slide 19.

[0035] The probe 1501 is detachably connected to the side of the sliding clamp 15.

[0036] The test piece 1 is provided with a press button 101 on its top.

[0037] The test piece 1 has a side terminal 102 on its side.

[0038] A driven belt 301 is provided below the guide platform 16, and the inner side of the driven belt 301 is connected to the transmission rod 4.

[0039] The working principle of this utility model is as follows: First, the test piece 1 to be tested is installed on the test base 2 through a detachable connection. The test base 2 plays a role in fixing and positioning the test piece 1, ensuring that the test piece 1 remains in a stable position during the subsequent testing process.

[0040] After the drive motor 6 is started, the output end of the drive motor 6 drives the drive belt 5 to rotate. The drive belt 5 transmits power to the transmission rod 4, causing the transmission rod 4 to rotate. The transmission rod 4 drives the transmission belt 3 connected to its inner side to rotate, and simultaneously drives the driven belt 301 below the guide table 16 to rotate. The transmission belt 3 then drives the test base 2 and test piece 1 carried above to move horizontally, realizing the automated transport of the test piece 1. The driven belt 301 drives the guide table 16 to move horizontally, and the moving speed of the guide table 16 is consistent with that of the test base 2, so as to ensure that the relative position between the components participating in the test and the test piece 1 remains stable.

[0041] When the size of test piece 1 is different and the test height needs to be adjusted to meet the test requirements, the drive cylinder 8 is activated. The output end of the drive cylinder 8 pushes the support frame 7 to move up and down in the vertical direction. The lifting and lowering of the support frame 7 will synchronously drive the transmission belt 3, the test base 2 and the test piece 1 to lift and lower together until the height of the test piece 1 meets the test requirements. At the same time, the first balance block 9 on one side of the support frame 7 will move synchronously with the support frame 7. The first balance block 9 drives the first balance plate 11 rotatably connected to it to rotate. The first balance plate 11 forms a cross-shaped hinge balance structure through the cross-rotation structure in the middle of the second balance plate 12, combined with the linkage of the third balance block 13 and the fourth balance block 14. This structure can effectively suppress the tilting and shaking that may occur during the lifting and lowering of the support frame 7, and ensure the stability of the test piece 1 during the height adjustment process.

[0042] During the top pressing test, the mounting plate 20 provides fixed support for the lifting slide 19. The lifting slide 19 is started, and the lifting slide 19 drives the test bar 18 on its side to move downward in the vertical direction, so that the test bar 18 contacts the pressing button 101 on the top of the test piece 1 and applies pressing force, thereby completing the test of the function of the pressing button 101 of the test piece 1. After the test is completed, the lifting slide 19 drives the test bar 18 to return to the top.

[0043] During the side electrical performance test, the probe 1501, which is detachably connected to the side of the sliding fixture 15, is used to contact the side terminal 102 on the side of the test piece 1. After the test piece 1 is transported to the designated test position, the drive cylinder 17 is activated. The output end of the drive cylinder 17 pushes the sliding fixture 15 to move horizontally along the sliding track of the guide table 16, so that the probe 1501 docks with the side terminal 102 on the side of the test piece 1. The probe 1501 conducts electrical signals through contact with the side terminal 102 to complete the test of the side electrical performance of the test piece 1. After the test is completed, the drive cylinder 17 drives the sliding fixture 15 to reset, and the probe 1501 separates from the side terminal 102.
