Description

Technical Field

[0001] The present invention relates to the technical field of electronic component testing, in particular to a pin tool used for electronic component qualification testing. Background Art

[0002] Electronic components refer to circuit elements with different functions that are soldered on various integrated circuit boards, thus providing different functional performances for different forms of integrated circuit boards, thereby assisting various fields and occasions to achieve the desired circuit display results. After the integrated circuit board with electronic components is soldered, it is necessary to conduct various pin circuit inspections and compare the inspection results of each component pin with the standard inspection results to detect qualified electronic component integrated boards. These qualified electronic component integrated boards are then produced for use in various fields of trading products.

[0003] However, the existing electronic component pin detection device still has a series of problems during use, such as:

[0004] First of all, the existing electronic component pin detection device is mostly a fixed whole. In the actual electronic component welding integrated board pin detection scenario, the integrated board full of electronic components is placed in the detection device, and then the detection machine board with the detection head is manually pressed down to the integrated board welding pin to complete the pin detection. However, due to the instability of manual operation, when the integrated board and the electronic component welding pins are detected, the hand force is too small, resulting in failure of the electronic component welding pin detection, unclear detection results, etc., or the hand force is too large, resulting in the integrated board with electronic components. The electronic component integrated board is crushed, deformed, and the like, which seriously affects the detection of the electronic component pins. In addition, the existing electronic component pin detection device can only detect the electronic component pins on one side of the integrated board, and cannot detect the pins at different positions of the electronic component integrated board. As a result, when the electronic component integrated board is being tested, the device cannot perform double-sided detection of the electronic component pins, resulting in insufficient detection of the pin path of the electronic component integrated board, abnormal pin power-on use, and scrapping of the electronic component integrated board, which seriously affects the normal detection of the pins of the electronic component integrated board.

[0005] Secondly, after the electronic component integrated board is inspected, there will be residual dust attached around the electronic component welding pins, and this dust needs to be cleaned. However, the existing electronic component pin inspection device cannot remove the dust around the electronic component pins. As a result, when the electronic component integrated board after inspection is used, due to the influence of the residual dust, the electronic component pins will produce arc burning, and the integrated board function will fail.

[0056] Compared with the prior art, the pin tooling for the qualified test of electronic components can solve the problem that the existing electronic component pin detection device cannot perform flip detection and distance adjustment detection on the pins of electronic components on the integrated board. Through the up and down movement of the concave clamping plate 209 and the L-shaped multi-slot carrier plate 206, the impact frame 216 and the concave rod 220 can perform knocking vibration detection and distance adjustment pin detection operations on the electronic component integrated board that moves up and down, so that the concave rod 220 after distance adjustment can detect the pins at different positions on the electronic component integrated board clamped by the concave clamping plate 209, thereby improving the detection strength of the electronic component pins and detecting the detection results of the electronic component integrated board in a vibration environment. Moreover, under the action of the meshing rotation of the gear 211 and the rack 213, the concave clamping plate 209 can be indirectly rotated to drive the electronic component integrated board to perform flipping and conversion operations, further detecting the pins on both sides of the electronic component integrated board, strengthening the integrity of the use of the conductive detection of the electronic components, and ensuring the efficient use of the electronic component integrated board.

[0057] In other aspects, this embodiment also provides a pin fixture for electronic component qualification testing, such as Figure 1 、 Figure 10 、 Figure 11 As shown, a wiping mechanism 300 is provided at the right end of the bidirectional flipping mechanism 200. The wiping mechanism 300 includes a telescopic electrostatic brush plate 301. The telescopic electrostatic brush plate 301 is located on the top of the concave clamping plate 209. The wiping mechanism 300 is used to perform mobile wiping and dust cleaning operations on the surface of the electronic component integrated circuit board clamped by the concave clamping plate 209 after detection and flipping.

[0058] The wiping mechanism 300 further includes a spring three 302 , which is fixedly connected between the inner walls of the telescopic electrostatic brush plate 301 .

[0059] Compared with the existing technology, the pin tooling for the qualified test of electronic components can solve the problem that the existing electronic component pin detection device cannot clean the dust on the pins of the electronic component integrated board after detection. Under the action of the continuous moving force of the concave clamping plate 209, the brush fibers on the brush head of the telescopic electrostatic brush plate 301 can wipe and clean the dust on the electronic component integrated board clamped by the concave clamping plate 209, further maintaining the cleanliness of the electronic component integrated board, reducing the corrosion and interference of dust and foreign matter on the electronic component integrated board, and ensuring the normal detection of the pins of the electronic component integrated board.

[0060] Working principle:

[0061] The first step is to manually place the body 100 on the workbench to be tested, and then place the integrated board with soldered electronic components on the clamping opening of the concave clamping plate 209 in the two-way flip mechanism 200. Manually rotate the screw rod 2 402 in the clamping mechanism 400 clockwise to drive the rotationally connected concave slide 401 to slide toward the concave clamping plate 209, thereby gradually clamping the integrated board of electronic components. When the concave slide 401 and the concave clamping plate 209 completely clamp the integrated board of electronic components, stop rotating the screw rod 202 and maintain the status quo.

[0062] Then, the bidirectional flip mechanism 200 starts to work, and the power is turned on to start the output shaft of the motor 201 to rotate counterclockwise, driving the fixedly connected screw rod 1 202 to rotate counterclockwise, and the rotation of the screw rod 1 202 drives the threaded L-shaped slide 203 to slide in the direction of the concave rod 220, and the L-shaped slide 203 drives the fixedly connected L-shaped multi-slot carrier plate 206 to move along the track of the slide rail 1 204 in the direction of the concave rod 220, so that the L-shaped multi-slot carrier plate 206 drives the two slide rails 207 fixedly connected at the top to move in the direction of the concave rod 220, and at the same time, the two slide rails 207 drive the connecting plate 208 to move in the direction of the concave rod 220, further making the connecting plate 208 drives the concave clamping plate 209 and the electronic component integrated board clamped by the clamping mechanism 400 to move toward the concave rod 220, thereby causing the concave clamping plate 209 to drive the fixedly connected gear 211 to move toward the concave rod 220, so that the gear 211 drives the fixedly connected column block 212 to slide along the inner track of the annular slide 205 toward the concave rod 220. When the column block 212 slides toward the concave rod 220 to the position of the limit block 214, under the action of the continuous movement of the L-shaped multi-card slot type carrier plate 206, the column block 212 can push the limit block 214 to flip clockwise with the bottom of the body 100 as the center, so that the column block 212 drives the connecting plate 208 and the concave clamping plate 209 to move toward the concave rod 220. 09 slides along the track of the two slide rails 207 toward the telescopic electrostatic brush plate 301. When the column block 212 slides to be flush with the bottom position of the annular slideway 205, the multiple slots at the bottom of the L-shaped multi-slot carrier plate 206 will be engaged with the top of the concave rod 220. Under the action of the continuous downward force of the L-shaped multi-slot carrier plate 206, the concave rod 220 engaged with the L-shaped multi-slot carrier plate 206 will move left and right along the track of the slide rail 3 218 and the balance frame 221, so that the concave rod 220 can use the left and right adjustment to detect different pins on the electronic component integrated board in the concave clamping plate 209, further avoiding the pins of the electronic component integrated board from being damaged. In order to detect the problem that the detection head cannot accurately contact the pin position due to excessive offset, the left and right separation of the concave rod 220 can be used to detect pins at different distances on the same plane, thereby increasing the detection degree of the pins of the electronic components and ensuring the normal use of the detection of the electronic component integrated board. Under the driving force of the downward movement of the L-shaped multi-slot carrier plate 206, the L-shaped multi-slot carrier plate 206 can push the concave rod 220 to slide downward along the track of the concave slider 219 after the card connection is slid, and then the concave rod 220 can push the fixedly connected detection head 222 to move toward the electronic component integrated board clamped by the concave clamping plate 209, thereby completing the first pin detection of the electronic component integrated board by the detection head 222;

[0063] Then, when the column block 212 moves to the bottom position of the annular slide 205, the power is disconnected, the rotation of the output shaft of the motor 201 is stopped, the first pin detection operation is completed, and then the power is turned on again to start the output shaft of the motor 201 to rotate clockwise, driving the fixedly connected screw rod 1 202 to rotate clockwise, and the rotation of the screw rod 1 202 drives the threaded L-shaped slide 203 to slide toward the impact frame 216, and the L-shaped slide 203 drives the L-shaped multi-slot carrier plate 206 to move along the track of the slide rail 1 204 toward the impact frame 216, so that the L-shaped multi-slot carrier plate 206 drives the two slide rails 207 fixed at the top to move toward the impact frame 216, and at the same time, the two slide rails 20 7 drives the connecting plate 208 to move in the direction of the impact frame 216, further causing the connecting plate 208 to drive the concave clamping plate 209 and the electronic component integrated board clamped by the clamping mechanism 400 to move in the direction of the impact frame 216, thereby causing the concave clamping plate 209 to drive the fixedly connected gear 211 to move in the direction of the impact frame 216, so that the gear 211 drives the fixedly connected column block 212 to slide along the inner track of the annular slide 205 in the direction of the impact frame 216. When the column block 212 slides to be flush with the position of the rack 213 on the right side of the body 100, it will drive the connecting plate 208 to drive the rotatably connected concave clamping plate 209 to slide along the trajectory of the slide groove 210 in the direction of the telescopic electrostatic brush plate 301, synchronously causing the gear 211 and The rack 213 contacts the rack 213, so that under the action of the force of the gear 211 continuously moving toward the impact frame 216, the gear 211 is engaged with the rack 213 and rotates clockwise, and at the same time, the gear 211 rotates to drive the fixed concave clamping plate 209 to rotate clockwise, thereby realizing that the concave clamping plate 209 drives the clamped electronic component integrated board to rotate clockwise. When the gear 211 rotates clockwise to the top of the rack 213, the concave clamping plate 209 and the electronic component integrated board clamped by the clamping mechanism 400 can complete a 90° flip. When the L-shaped multi-card slot carrier plate 206 moves to be flush with the position of the telescopic electrostatic brush plate 301 in the wiping mechanism 300, the top of the concave clamping plate 209 can gradually squeeze the telescopic electrostatic brush plate 301. The brush portion of the electrostatic brush plate 301 contracts inwardly, and the spring three 302 is fixedly connected between the inner walls of the telescopic electrostatic brush plate 301, so that the spring three 302 can provide stable elastic support for the telescopic electrostatic brush plate 301 to extend and retract, and under the action of the continuous moving force of the concave clamping plate 209, the brush fibers on the brush head of the telescopic electrostatic brush plate 301 can wipe and clean the dust on the electronic component integrated board clamped by the concave clamping plate 209, further maintaining the cleanliness of the electronic component integrated board, reducing the corrosion and interference of dust and foreign matter on the electronic component integrated board, and ensuring the normal detection of the pins of the electronic component integrated board. The spring three 302 is fixedly connected between the inner walls of the telescopic electrostatic brush plate 301,The spring 302 can provide stable elastic support for the extension and contraction of the telescopic electrostatic brush plate 301;

[0064] When the column block 212 slides to be flush with the position of the limit block 214, under the action of the continuous moving force of the L-shaped multi-slot carrier plate 206, the column block 212 pushes the limit block 214 to flip clockwise with the top of the body 100 as the center, so that the column block 212 drives the concave splint 209 fixedly connected to the gear 211 to slide along the two slide rails 207 tracks toward the direction of the slide rail 1 204, and at the same time, the concave splint 209 pushes the rotatably connected 208 to slide along the two slide rails 207 tracks toward the direction of the slide rail 1 204. When the column block 212 slides to be flush with the top position of the annular slide 205, the L-shaped slide plate 203 can indirectly drive the connecting plate 208 to push the bottom of the impact frame 216 to rotate clockwise with the spring 217 as the center, so that the top of the impact frame 216 can flip clockwise toward the direction of the concave splint 209, and the impact The top of the impact frame 216 contacts the top of the concave clamping plate 209, making a collision sound, thereby realizing that the impact frame 216 can perform a knocking vibration operation on the electronic component integrated board after wiping and cleaning, further vibrating and cleaning the dust on the surface of the electronic component integrated board after wiping, and assisting the concave clamping plate 209 to perform a vibration shedding detection operation on the pins soldered on the clamped electronic component integrated board, and further detecting whether there is a pin unsoldered on the electronic component integrated board, thereby ensuring the normal use of the electronic component integrated board in different environments, and the spring 1 215 is fixedly connected to the inner wall of the limit block 214, so that the spring 1 215 can provide stable elastic rotational force support for the flipping of the limit block 214, and the spring 217 is fixedly connected between the inner walls of the impact frame 216, so that the spring 217 can provide stable elastic support for the rotation of the impact frame 216;

[0065] When the operator observes that the column block 212 has moved to the top position of the annular slide 205 and the connecting plate 208 and the impact frame 216 make a knocking vibration sound, the operator manually disconnects the power supply, pauses the rotation of the output shaft of the motor 201, completes the first knocking vibration detection process, and then turns on the power again to start the output shaft of the motor 201 to rotate counterclockwise, driving the fixedly connected screw rod 1 202 to rotate counterclockwise, and causing the screw rod 1 202 to rotate and drive the threaded L-shaped slide plate 203 to slide in the direction of the concave rod 220, and causing the L-shaped slide plate 203 to drive the L-shaped multi-slot carrier plate 206 to move along the trajectory of the slide rail 1 204 in the direction of the concave rod 220, so that the L-shaped multi-slot carrier plate 206 drives the two slide rails 202 fixedly connected at the top. 7 moves in the direction of the concave rod 220, and at the same time, the two slide rails 207 drive the connecting plate 208 to move in the direction of the concave rod 220, and further make the connecting plate 208 drive the concave clamping plate 209 and the electronic component integrated board clamped by the clamping mechanism 400 to move in the direction of the concave rod 220, and then make the concave clamping plate 209 drive the fixedly connected gear 211 to move in the direction of the concave rod 220, so that the gear 211 drives the fixedly connected column block 212 to slide along the inner track of the annular slideway 205 in the direction of the concave rod 220. When the column block 212 slides to be flush with the rack 213 on the left side of the body 100, it will drive the connecting plate 208 to drive the rotatably connected concave clamping plate 209 to move along the track of the slide groove 210 to the inner track of the slide rail 1 204. The gear 211 slides in the direction of the concave rod 220, and the gear 211 is brought into contact with the rack 213 synchronously. As a result, under the action of the force of the gear 211 continuously moving in the direction of the concave rod 220, the gear 211 and the rack 213 are meshed for the second time and rotate clockwise. At the same time, the rotation of the gear 211 drives the fixedly connected concave clamping plate 209 to rotate clockwise, thereby realizing that the concave clamping plate 209 drives the clamped electronic component integrated board to rotate clockwise. When the gear 211 rotates clockwise to the top of the rack 213, the electronic component integrated board clamped by the concave clamping plate 209 and the clamping mechanism 400 can complete a 90° flip, thereby realizing the flipping operation of the electronic component integrated board, further detecting the pins on both sides of the electronic component integrated board, and strengthening the electronic component integrated board. When the column block 212 slides to be flush with the position of the limit block 214, the column block 212 can push the limit block 214 to flip clockwise with the bottom of the body 100 as the center under the action of the continuous movement of the L-shaped multi-slot carrier plate 206, so that the column block 212 drives the connecting plate 208 and the concave clamping plate 209 to slide along the track of the two slide rails 207 toward the direction of the telescopic electrostatic brush plate 301. When the column block 212 slides to be flush with the bottom position of the annular slide 205, the multiple slots at the bottom of the L-shaped multi-slot carrier plate 206 will be engaged with the top of the concave rod 220, and under the action of the continuous downward force of the L-shaped multi-slot carrier plate 206,The concave rod 220 engaged with the L-shaped multi-slot carrier plate 206 will move left and right along the track of the slide rail 3 218 and the balance frame 221, thereby allowing the concave rod 220 to perform a secondary distance adjustment detection operation on different pins on the electronic component integrated board in the concave clamping plate 209, and driven by the downward movement force of the L-shaped multi-slot carrier plate 206, the L-shaped multi-slot carrier plate 206 can push the engaged and sliding concave rod 220 to slide downward along the track of the concave slider 219, thereby allowing the concave rod 220 to push the fixedly connected detection head 222 to move toward the electronic component integrated board clamped by the concave clamping plate 209, thereby allowing the detection head 222 to effectively contact the pins on the electronic component integrated board, thereby increasing the contact area and contact force between the detection head 222 and the pins on the electronic component integrated board, and ensuring that the detection head 222 can effectively complete the second pin detection of the electronic component integrated board.

[0066] In the second step, similarly, when the column block 212 moves to the bottom position of the annular slide 205, the power is disconnected, the rotation of the output shaft of the motor 201 is paused, the second pin detection operation is completed, and then the power is turned on again to start the output shaft of the motor 201 to rotate clockwise for the next cycle of tapping and vibration detection. After the second tapping and vibration detection of the electronic component integrated board is completed, the screw rod 2 402 is manually rotated counterclockwise to drive the rotating concave slide 401 to slide away from the concave clamping plate 209, and then gradually loosen the electronic component integrated board that has been inspected, and then manually take out the inspected electronic component integrated board. If there are still uninspected welded electronic component integrated boards, the above steps can be followed to perform the cycle operation. After all electronic component integrated boards have been inspected, the power can be disconnected, the rotation of the output shaft of the motor 201 can be stopped, the device stops running, and the detection is completed.
