Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to an electronic component testing instrument. Background Technology

[0002] After electronic components are soldered to circuit boards, they need to be tested. Instruments that quantitatively measure parameters such as resistance, capacitance, frequency characteristics, and logic functions of components such as resistors, capacitors, transistors, and integrated circuits include basic parameter testers, semiconductor characteristic analyzers, and integrated circuit functional testers. An integrated circuit functional tester is a device for testing electronic components.

[0003] During the testing process, the circuit board needs to be fixed. The structural clamps not only occupy the operating space of the circuit board, but also the process of fixing the circuit board is time-consuming. Therefore, we propose an electronic component tester to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an electronic component tester.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic component tester, comprising a tester, a support frame, a support column, a fixing frame, a plug rod, and a mounting cylinder. The tester is provided with a support frame above it, and a fixing frame is provided at the upper end of the support frame. The fixing frame contains mounting cylinders arranged in a rectangular array. A piston is provided inside the mounting cylinder. A valve seat and a valve ring are provided on the lower inner wall of the mounting cylinder. A valve spring is provided at the upper end of the valve seat. A valve core with a conical outer wall and inserted into the valve ring is provided at the upper end of the valve spring. A mounting column is provided above the plug rod. A connecting pipe is connected to one side of the lower end of the mounting cylinder. One end of the connecting pipe is connected to a mounting pipe that is closed at both ends.

[0006] Preferably, a screw is rotatably mounted on the upper end of the detector, and the outer wall of the screw is provided with rotating rods arranged in a ring array. The support frame has a threaded hole inside for threaded connection with the screw. The screw rotates inside the threaded hole, raising and adjusting the guiding support frame. By gripping the rotating rods, rotational force can be easily applied to the screw.

[0007] Preferably, sliding sleeves are embedded in the interior of each of the four corners of the support frame, and a guide rod is slidably installed inside the sliding sleeve at the upper end of the detector. The four corners of the support frame are slidably installed with the guide rod via the sliding sleeves, thus providing longitudinal sliding guidance for the support frame.

[0008] Preferably, a pressure plate is provided on one side of the fixing frame, and a gripping groove is provided inside one end of the pressure plate. A support rod is provided on the upper side of the pressure plate. The pressure rod is used to press down on the upper end of the support column and limit the height of the support rod after it is raised to avoid uneven height of the support column. The rotating pressure plate causes the support rod to fit against the upper end of the support frame, thereby positioning the height of the pressure plate. The gripping groove facilitates hand gripping and use.

[0009] Preferably, symmetrically distributed bearing supports are provided on one side of the upper end of the fixing frame, and a rotating shaft is provided at one end of the pressure plate. The rotating shaft is rotatably installed inside the bearing supports. The bearing supports provide rotational support for the rotating shaft, and the rotating shaft provides rotational support for one end of the pressure plate, so that the pressure plate can be rotated to press the upper end of the support column during use.

[0010] Preferably, one end of the support frame is equipped with an air pump, and the output end of the air pump is connected to the mounting pipe. The air pump is used to pressurize the inside of the mounting pipe, which then enters the mounting cylinder through the connecting pipe to apply a lifting force to the piston.

[0011] Preferably, the upper end of the stopper rod is provided with a rotating seat, and the lower end of the mounting column is rotatably mounted inside the rotating seat. During use, the rotating seat provides rotational support to the bottom of the support column, allowing for selective compression of the support column sidewalls and reducing friction and resistance of the compression components.

[0012] Preferably, the outer wall of the support column has positioning holes arranged in a ring array. Positioning rods are slidably installed inside each positioning hole. Each positioning rod has a side strip at one end, and a guide surface is provided on one side of the upper end of each side strip. A spring, connected to the mounting column and the side strip, is sleeved on the outer side of the positioning rod. When the circuit board is located in the adapting groove where the support column descends, the side wall fits against the support strip, which is elastically supported by the spring, thus elastically clamping the side wall of the power board. The guide surface reduces the resistance during the descent of the circuit board and guides it.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves placing the circuit board of a welded electronic component on the upper end of a support column and inspecting it with a testing instrument. The support columns supporting the bottom of the circuit board are arranged in a rectangular array with small gaps between them. The support columns are movably inserted into the mounting cylinder. When the support column is squeezed, the pressure inside the mounting cylinder is output, and the output port is supported by an elastically supported valve spring to maintain the stability of the air pressure inside the mounting cylinder after being pressed. This allows the support column to be positioned after descending. A groove matching the shape of the circuit board is formed in the central area of ​​the rectangular array of support columns. The circuit board of the welded electronic component avoids the clamping of structural components. The circuit board of the welded electronic component is positioned during the inspection process by gently pressing it, avoiding the side clamping of the circuit board of the welded electronic component from affecting the space of the inspection operation. At the same time, the inspection and fixing process of the welded electronic component circuit board is time-saving. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes an electronic component tester, including a tester 1, a support frame 2, a support column 5, a fixing frame 6, a plug rod 20, and a mounting cylinder 18. The support frame 2 is provided above the tester 1, and the fixing frame 6 is provided at the upper end of the support frame 2. The mounting cylinder 18 is arranged in a rectangular array inside the fixing frame 6. A piston is provided inside the mounting cylinder 18. A valve seat 29 and a valve ring 26 are provided on the lower inner wall of the mounting cylinder 18. A valve spring 27 is provided at the upper end of the valve seat 29. A valve core 25 with a conical outer wall and inserted into the valve ring 26 is provided at the upper end of the valve spring 27. A mounting column is provided above the plug rod 20. A connecting pipe 19 is connected to one side of the lower end of the mounting cylinder 18. One end of the connecting pipe 19 is connected to a mounting pipe 4 with both ends closed.

[0023] The upper end of the detector 1 is rotatably mounted with a screw 9, and the outer wall of the screw 9 is provided with rotating rods 8 arranged in a ring array. The support frame 2 has a screw hole 10 inside that is threadedly connected to the screw 9.

[0024] Sliding sleeves 12 are embedded in the four corners of the support frame 2, and a guide rod 11 is slidably installed inside the sliding sleeve 12 at the upper end of the detector 1.

[0025] A pressure plate 7 is provided on one side of the fixed frame 6. A gripping groove 15 is provided inside one end of the pressure plate 7. A support rod 16 is provided on one side of the upper end of the pressure plate 7.

[0026] A symmetrically distributed bearing bracket 13 is provided on one side of the upper end of the fixed frame 6, and a rotating shaft 14 is provided on one end of the pressure plate 7. One end of the rotating shaft 14 is rotatably installed inside the bearing bracket 13.

[0027] One end of the support frame 2 is equipped with an air pump 3, and the output end of the air pump 3 is connected to the installation pipe 4;

[0028] The upper end of the stopper rod 20 is provided with a rotating seat 23, and the lower end of the mounting column is rotatably mounted inside the rotating seat 23;

[0029] The outer wall of the support column 5 has positioning holes 22 arranged in a ring array. Positioning rods 28 are slidably installed inside each positioning hole 22. One end of each positioning rod 28 is provided with a side strip 21. A guide surface 17 is provided on one side of the upper end of the side strip 21. A spring 24 connected to the mounting column and the side strip 21 is sleeved on the outside of the positioning rod 28.

[0030] Based on the implementation steps of Example 1: During operation, the soldered circuit board is gently placed above the array of support columns 5. When the circuit board's own weight presses against the support column 5, the lower end plug rod 20 of the support column 5 pushes the piston to compress the air in the mounting cylinder 18, forcing the airflow to push the valve spring 27 to push the conical valve core 25 away from the valve ring 26, forming a pressure balance. At this time, the spring 24 applies an elastic clamping force to the side wall of the circuit board through the side strip 21, and the guide surface 17 ensures that the circuit board descends smoothly. When the compression ends, the valve spring 27 resets and closes the airflow channel, finally forming a positioning groove in the center of the array of support columns 5 that is completely fitted with the shape of the circuit board. After the test is completed, the air pump 3 is started, and compressed air is injected into the mounting cylinder 18 through the mounting pipe 4 and the connecting pipe 19. The air pressure acts on the lower end of the piston, and the mounting cylinder 18 inside the lower end of the piston is lifted after the air pressure is replenished. The compressed support column 5 rises, so that the circuit board is lifted out and contacts the positioning of the circuit board. The side strip 21 is automatically reset under the action of the spring 24.

[0031] The support column 5 and the mounting cylinder 18 form a pneumatic buffer system. The pressure dynamic balance is achieved through the structure of valve spring 27 and valve core 25. When the support column 5 is compressed, the airflow forms a controllable resistance through the valve ring 26, so that the descent speed of the support column 5 matches the gravity of the circuit board and avoids rigid impact. The side strip 21 forms an elastic clamping module through spring 24 and positioning rod 28. The guide surface 17 converts the lateral pressure of the circuit board into the compression of spring 24, ensuring that the clamping force is automatically adjusted according to the thickness of the circuit board. The sliding insertion design of the support column 5 and the mounting cylinder 18, together with the positioning holes 22 distributed in a ring array, allows the spacing of the support column 5 to adapt to circuit boards of different sizes and avoids positioning errors.

[0032] The circuit board positioning time is shortened, the compatibility range is improved, and the space utilization rate is increased. The gap between the support pillars 5 is reduced compared to traditional fixtures, allowing for a denser arrangement of test probes and increased test density. The elastic positioning system ensures uniform force distribution on the circuit board, preventing damage to electronic components and solving the problem of traditional fixtures occupying operating space. Pneumatic elastic positioning enables convenient clamping, and the density of test probes can be increased, avoiding circuit board fixing losses. The self-weight trigger positioning mechanism shortens the positioning time and improves positioning accuracy. The ring array support pillars 5 and the pneumatic buffer system reduce the warpage of the circuit board, meeting the testing requirements of micro-components. It is particularly suitable for testing high-density circuit boards such as mobile phone motherboards and smart wearable devices.
