Description

Technical Field

[0001] The present invention relates to the technical field of circuit board detection, and particularly to a detection platform for the compressive performance of a circuit board. Background Art

[0002] Based on the prior art, it is found that when the existing circuit board detection equipment detects a circuit board, it usually only applies pressure to the middle position of the circuit board, and cannot flexibly adjust the pressure application position on the circuit board, resulting in incomplete force coverage of the circuit board. For example, the edge area or specific functional parts are more likely to be affected by external forces. If only the middle area is tested, the compressive performance of other key positions cannot be reflected, thus affecting the accuracy of the detection results. In addition, during the actual use of the circuit board, it will be affected by the use environment, resulting in changes in the performance of the circuit board. However, the existing detection equipment fails to simulate the actual use environment of the circuit board and does not detect the circuit board after the performance has changed, resulting in great limitations in the detection.

[0014] The advantages and positive effects of the present invention are as follows: (1) By jointly clamping and limiting the circuit board with four clamping blocks, and then making the ejector rod move longitudinally and horizontally, the position of the ejector rod relative to the circuit board can be automatically adjusted, so as to flexibly adjust the pressing position for multiple circuit boards of the same batch. Then, make the ejector rod move downward to press the circuit board, and the pressure applied to the circuit board has been preset in advance. Then, control the vision sensor to start operating to detect the circuit board, so as to know the compressive performance of the circuit board within the set pressure range, thereby realizing the compressive test of the circuit board and improving the accuracy of the test results.

[0015] (2) By successively inputting hot air or cold air into the two conduits through an external air pump, the gas enters the conduit and then is discharged through the corresponding branch pipes and flows into the box body, thereby changing the temperature environment in the box body, so that the circuit board can quickly be in a high-temperature or low-temperature environment. Then, press the circuit board again to detect the compressive performance of the circuit board in the high-temperature or low-temperature environment, thereby reducing the limitations in the compressive performance test of the circuit board and further improving the accuracy of the test results.

[0016] (3) Move the box body forward until it moves away from the support column, and then control the two vibration motors to start, so that the box body vibrates up and down. Since the inner bottom of the box body is provided with an inverted trapezoidal groove, when the box body vibrates up and down, the debris and scraps in the box body all move to the electric opening and closing plate. Then, control the electric opening and closing plate to open, so that the debris and scraps in the box body flow out and are collected by an external collection box, thereby realizing the cleaning of the debris and scraps in the box body for subsequent use.

[0017] (4) By injecting gas into the two conduits and controlling the solenoid valves installed on the two branch pipes to close, the gas can only flow out through the other end of the conduit, so that the gas blows into the box body, thereby blowing the debris and scraps in the box body by the gas and reducing the phenomenon that the debris and scraps adhere to the inner wall of the box body, thereby improving the cleaning effect of the box body.

[0018] (5) Through the setting of the dust-proof member, the slide plate on the electric slider III drives the corresponding clamping block to move when moving. The movement of the clamping block causes the dust-proof member to deform adaptively, so as to shield the upper part of the fixed box through the dust-proof member, thereby preventing the fragments and debris generated when the circuit board is broken from entering the fixed box and affecting the normal operation of the equipment.

Specific implementation manner

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners, but the protection scope and application scope of the present invention are not limited. Embodiment

[0022] A circuit board compressive performance detection table, according to Figures 1 - 7 As shown, it includes a frame 1, an electric actuator 2 and a pressing plate 21; an electric actuator 2 is installed on the frame 1, and the electric actuator 2 is a hydraulic cylinder; the telescopic part of the electric actuator 2 is fixedly connected with the pressing plate 21; It also includes a vision sensor 11, support columns 201, a box body 202, electric cover plates 203, a rectangular frame 204, a sliding plate 205, elastic members I 206, an automatic positioning component, an ejector rod 211 and an electric clamp; a vision sensor 11 is installed on the frame 1; two support columns 201 are connected to the frame 1; a box body 202 is slidably connected to all the support columns 201; two electric cover plates 203 are installed on the box body 202, and the electric cover plates 203 are composed of a motor and a transparent acrylic plate, and the output shaft of the motor rotates to drive the transparent acrylic plate to rotate; a rectangular frame 204 is fixedly connected to one of the electric cover plates 203; a sliding plate 205 is slidably connected to the rectangular frame 204, and four elastic members I 206 are fixedly connected between the rectangular frame 204 and the sliding plate 205, and the elastic members I 206 are springs; an automatic positioning component is connected to the sliding plate 205; the automatic positioning component is connected to the ejector rod 211; an electric clamp is connected to each support column 201.

[0023] The automatic positioning component includes an electric slide rail I 207, an electric slider I 208, an electric slide rail II 209 and an electric slider II 210; two electric slide rails I 207 are fixedly connected to the lower surface of the sliding plate 205; an electric slider I 208 is slidably connected to each electric slide rail I 207; an electric slide rail II 209 is fixedly connected to all the electric sliders I 208 together; an electric slider II 210 is fixedly connected to the electric slide rail II 209; the electric slider II 210 is fixedly connected to the ejector rod 211.

[0024] The electric fixture includes a fixed box 212, an electric slide rail III 213, an electric slider III 214, a slide plate 215 and a clamping block 216; a fixed box 212 is fixedly connected to each support column 201; an electric slide rail III 213 is fixedly connected to the inner bottom of each fixed box 212; an electric slider III 214 is slidably connected to each electric slide rail III 213; a slide plate 215 is fixedly connected to each electric slider III 214, and another slide plate 215 is fixedly connected to each fixed box 212; a clamping block 216 is connected to each slide plate 215.

[0025] A rubber strip is arranged on the clamping block 216 to increase the friction between the clamping block 216 and the circuit board 3.

[0026] It also includes a conduit 301 and a branch pipe 302; a conduit 301 is fixedly connected to each support column 201; each conduit 301 is fixedly connected to the corresponding fixed box 212; a branch pipe 302 is fixedly connected and communicated with each conduit 301.

[0027] The peripheral air pump is pre-connected to the two conduits 301, and the initial state of the two electric covers 203 is open. After the circuit board 3 is manually placed into the box body 202, then control the two electric covers 203 to close, so that a closed space is formed in the box body 202. When detecting the circuit board 3, since the existing detection equipment usually only applies pressure to the middle position of the circuit board 3 when detecting the circuit board 3, so as to perform a compressive test on the circuit board 3, but cannot flexibly adjust the pressure application position on the circuit board 3 for multiple circuit boards 3 of the same batch, which leads to incomplete force coverage of the circuit board 3, and further affects the accuracy of the detection result; To solve the above problems, after the circuit board 3 is placed into the box body 202, the upper surfaces of the two fixed boxes 212 are used to support the circuit board 3, and the circuit board 3 is located between the four sliding plates 215. Then, all the electric sliders III 214 are controlled to start and move along an electric slide rail III 213 respectively. Each electric slider III 214 drives a corresponding sliding plate 215 to move when it moves. Each sliding plate 215 drives a corresponding clamping block 216 to move when it moves. As a result, the two clamping blocks 216 move to abut against one side of the circuit board 3 and continue to move, and then the circuit board 3 is pushed to move by the synchronous movement of the two clamping blocks 216 until the other side of the circuit board 3 abuts against the clamping blocks 216 fixed on the fixed box 212. Thus, the circuit board 3 is clamped and limited by the cooperation of the four clamping blocks 216.

[0028] After the circuit board 3 is clamped and limited, the wires arranged in the sliding plate 205 are connected to an external power supply for power supply. Then, according to the program setting, the two electric sliders I 208 are controlled to start and move along an electric slide rail I 207 respectively. The two electric sliders I 208 move together to drive the electric slide rail II 209 to move. As a result, the electric slide rail II 209 moves longitudinally from top to bottom with the upper part of the sliding plate 205 as the reference. The electric slide rail II 209 moves to drive all the connected components to move, and then drives the ejector rod 211 to move longitudinally. Then, the electric slider II 210 is controlled to start and move horizontally along the electric slide rail II 209, so that the position of the ejector rod 211 relative to the circuit board 3 can be automatically adjusted according to the program setting. Then, the electric actuator 2 is controlled to start. The telescopic part of the electric actuator 2 moves to drive the pressing plate 21 to move downward. The pressing plate 21 moves to abut against the upper surface of the sliding plate 205 and drives the sliding plate 205 to move downward, thus compressing all the elastic members I 206. The sliding plate 205 moves to drive all the connected components to move downward, and then drives the ejector rod 211 to move downward. Then, the circuit board 3 is pressed by the downward movement of the ejector rod 211, and the pressure applied to the circuit board 3 has been preset. Then, the visual sensor 11 is controlled to start operating to detect the circuit board 3. If the circuit board 3 does not crack during the pressing process, it means that the circuit board 3 meets the production standard. On the contrary, if the circuit board 3 cracks during the pressing process, it means that the circuit board 3 does not meet the production standard. Thus, the compressive performance of the circuit board 3 within the set pressure range can be known, and the compressive detection of the circuit board 3 is realized. After the detection is completed, the circuit board 3 is taken out. After the next circuit board 3 is placed into the box body 202, the position of the ejector rod 211 relative to the circuit board 3 is adjusted, and then the circuit board 3 is pressed in the same way as above, and the compressive performance of the circuit board 3 is detected. Thus, the pressing position can be flexibly adjusted for multiple circuit boards 3 of the same batch, so as to improve the accuracy of the detection result.

[0029] And since the circuit board 3 will be affected by the use environment during actual use, resulting in changes in the performance of the circuit board 3, and the existing detection equipment fails to simulate the actual use environment of the circuit board 3 and also fails to detect the circuit board 3 after the performance changes, resulting in great limitations in detection. To solve the above problems, the peripheral air pump is controlled to operate to first input hot air into the two conduits 301, and then input cold air into the two conduits 301. After the gas enters the conduits 301, it is discharged through the corresponding branch pipes 302 and flows into the box body 202, thereby changing the temperature environment in the box body 202. And since a closed space has been formed inside the box body 202 when detecting the circuit board 3, it is possible to quickly make the circuit board 3 in a high-temperature or low-temperature environment. Then, the circuit board 3 is pressurized in the same way as above, so as to detect the compressive performance of the circuit board 3 in a high-temperature or low-temperature environment, thereby reducing the limitations existing in the detection of the compressive performance of the circuit board 3, and further improving the accuracy of the detection results. Embodiment

[0030] On the basis of Embodiment 1, according to Figure 6 and Figures 8 - 11 As shown, it further includes a vibration chip removal system; a vibration chip removal system is connected to the box body 202; the vibration chip removal system includes an electric opening and closing plate 2021, an elastic member II 217, an electric slide rail IV 401, an electric slider IV 402, a bracket 403, a slide bar 404, an elastic member III 405, a mounting frame 406, a vibration motor 407 and a pressing block 408; an electric opening and closing plate 2021 is connected to the lower part of the box body 202, and the electric opening and closing plate 2021 is composed of a motor and a rectangular plate. The output shaft of the motor rotates to drive the rectangular plate to rotate, and the rectangular plate is used to carry the chips; two elastic members II 217 are fixedly connected between each slide plate 215 and the corresponding clamping block 216, and the elastic member II 217 is a spring; two electric slide rails IV 401 are fixedly connected to the lower part of the frame 1; two electric sliders IV 402 are slidably connected to each electric slide rail IV 401; all the electric sliders IV 402 on the same electric slide rail IV 401 are jointly fixedly connected to a bracket 403; two slide bars 404 are fixedly connected to each bracket 403; one end of all the slide bars 404 on the same bracket 403 away from the electric slide rail IV 401 is fixedly connected to the box body 202; a spring, which is an elastic member III 405, is sleeved on the outer side of each slide bar 404. One end of the elastic member III 405 is fixedly connected to the bracket 403, and the other end of the elastic member III 405 is fixedly connected to the box body 202; two mounting frames 406 are fixedly connected to the lower surface of the box body 202; a vibration motor 407 is fixedly connected to each mounting frame 406; two notches matching with the columns 201 are opened on the box body 202, and a pressing block 408 is fixedly connected in each notch.

[0031] An inverted trapezoidal groove is provided at the inner bottom of the box body 202 for guiding the debris conveyed after the circuit board 3 is broken.

[0032] An electromagnetic valve is installed on each branch pipe 302, and the conduit 301 penetrates through the entire fixed box 212 and protrudes from the side of the fixed box 212 for blowing air into the box body 202 after displacement.

[0033] It also includes a convex block 2161; a convex block 2161 that cooperates with the corresponding pressing block 408 is fixedly connected to the upper part of each clamping block 216.

[0034] It also includes a dust-proof member 409; a dust-proof member 409 is fixedly connected between the sliding plate 215 connected to the electric slider III 214 and the corresponding fixed box 212. The dust-proof member 409 is an elastic cloth, and another dust-proof member 409 is fixedly connected between all the sliding plates 215 in the same fixed box 212.

[0035] When the circuit board 3 breaks during the compressive strength test, a large number of fragments and debris will be generated after the circuit board 3 breaks. And because the positions where the circuit board 3 is pressed during the test are different, the positions where the circuit board 3 breaks are also different, resulting in the fragments and debris generated when the circuit board 3 breaks not being concentrated and flying everywhere. And the fragments and debris are all inside the box body 202. Therefore, it is necessary to uniformly collect and clean the fragments and debris inside the box body 202 for subsequent use.

[0036] Pre-place the peripheral collection box at the designated position, and then control all the electric sliders IV 402 to start moving forward along the corresponding electric slide rails IV 401 with the front side of the frame 1 as the reference. The movement of every two electric sliders IV 402 drives the corresponding bracket 403 to move, and the movement of the bracket 403 drives the corresponding sliding rod 404 to move. All the sliding rods 404 move synchronously to drive the box body 202 to move. To avoid the clamping block 216 blocking the movement of the box body 202, through the setting of the pressing block 408, when the box body 202 moves forward, the movement of the box body 202 drives the two pressing blocks 408 to move, so that the pressing block 408 moves to touch the convex block 2161 on the clamping block 216 and squeezes the convex block 2161, causing the convex block 2161 to move downward and compress the corresponding elastic member II 217, so that the clamping block 216 moves downward into the corresponding sliding plate 215, thus avoiding the clamping block 216 blocking the movement of the box body 202, so that the box body 202 can move forward smoothly until the box body 202 moves away from the support column 201, as Figure 10As shown, then control the two vibration motors 407 to start, so that the box body 202 vibrates up and down, and all the elastic members III 405 undergo adaptive deformation. And because an inverted trapezoidal groove is provided at the inner bottom of the box body 202, when the box body 202 vibrates up and down, the fragments and debris in the box body 202 all move to the electric opening and closing plate 2021. Then control the electric opening and closing plate 2021 to open, so that the fragments and debris in the box body 202 flow out and are collected by an externally provided collection box, thereby realizing the cleaning of the fragments and debris in the box body 202 for subsequent use.

[0037] And because the conduit 301 penetrates through the entire fixed box 212 and protrudes from the side of the fixed box 212, after the box body 202 moves, the conduit 301 can still ventilate into the box body 202. Then control the externally provided air pump to operate to supply air into the two conduits 301, and control the solenoid valves installed on the two branch pipes 302 to close. Then the gas can only flow out through the other end of the conduit 301, so that the gas blows into the box body 202, thereby blowing the fragments and debris in the box body 202 by the gas, reducing the phenomenon that the fragments and debris adhere to the inner wall of the box body 202, and thus improving the cleaning effect of the box body 202.

[0038] It should be noted that through the setting of the dust-proof member 409, when the slide plate 215 on the electric slider III 214 moves, it drives the corresponding clamping block 216 to move. The movement of the clamping block 216 causes the dust-proof member 409 to undergo adaptive deformation, so as to shield the upper part of the fixed box 212 through the dust-proof member 409, thereby preventing the fragments and debris generated when the circuit board 3 is broken from entering the fixed box 212 and affecting the normal operation of the equipment.
