Description

Technical Field

[0001] This invention relates to the field of circuit board testing technology, and in particular to a circuit board compressive strength testing platform. Background Art

[0002] Based on existing technology, it has been found that existing circuit board testing equipment typically only applies pressure to the middle of the circuit board during testing, without being able to flexibly adjust the pressure application position according to the circuit board. This results in incomplete force coverage of the circuit board. For example, edge areas or specific functional parts are more susceptible to external forces. If only the middle area is tested, the compressive strength of other key locations cannot be reflected, thus affecting the accuracy of the test results.

[0003] Furthermore, during actual use, circuit boards are affected by the operating environment, causing changes in their performance. Existing testing equipment cannot simulate the actual operating environment of circuit boards, nor can it test circuit boards with changed performance, resulting in significant limitations in testing.

[0014] More preferably, it also includes a dustproof component; a dustproof component is fixed between the slide plate connected to the electric slider III and the corresponding fixed box, and another dustproof component is fixed between all slide plates in the same fixed box.

[0015] The advantages and positive effects of this invention are:

[0016] (1) The circuit board is clamped and limited by four clamping blocks, and then the push rod moves longitudinally and laterally, thereby automatically adjusting the position of the push rod relative to the circuit board. This allows for flexible adjustment of the pressure position for multiple circuit boards in the same batch. The push rod then moves downward to apply pressure to the circuit board. The pressure applied to the circuit board has been preset. The vision sensor is then activated to detect the circuit board, thereby determining the compressive strength of the circuit board within the set pressure range. This enables the circuit board to be tested for compressive strength and improves the accuracy of the test results.

[0017] (2) Hot or cold air is successively introduced into the two conduits by an external air pump. After the gas enters the conduit, it is discharged through the corresponding branch pipe and flows into the box, thereby changing the temperature environment inside the box. This allows the circuit board to be quickly placed in a high-temperature or low-temperature environment. Then, pressure is applied to the circuit board to detect its compressive strength under high-temperature or low-temperature conditions. This reduces the limitations of testing the compressive strength of the circuit board and further improves the accuracy of the test results.

[0018] (3) Move the box forward until it is detached from the support column, then start the two vibration motors to make the box vibrate up and down. Since there is an inverted trapezoidal groove on the bottom of the inner side of the box, when the box vibrates up and down, the fragments and debris inside the box will move to the electric opening and closing plate. Then control the electric opening and closing plate to open, so that the fragments and debris inside the box will flow out and be collected by the external collection box, thereby cleaning the fragments and debris inside the box for subsequent use.

[0019] (4) By supplying 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, thereby blowing the gas into the box. This blows the fragments and debris inside the box, reducing the phenomenon of fragments and debris adhering to the inner wall of the box, thus improving the cleaning effect of the box.

[0020] (5) By setting up dustproof components, the sliding plate on the electric slider III moves and drives the corresponding clamping block to move. The movement of the clamping block causes the dustproof components to deform adaptively, thereby shielding the upper part of the fixed box through the dustproof components, thus preventing fragments and debris generated when the circuit board breaks from entering the fixed box and affecting the normal operation of the equipment.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention. Example

[0034] A circuit board compressive strength testing platform, based on Figures 1-7 As shown, it includes a frame 1, an electric actuator 2, and a pressure plate 21; the electric actuator 2 is mounted on the frame 1, and the electric actuator 2 is a hydraulic cylinder; the extension part of the electric actuator 2 is fixedly connected to the pressure plate 21.

[0035] It also includes a vision sensor 11, a support column 201, a housing 202, an electric cover plate 203, a rectangular frame 204, a sliding plate 205, elastic elements I 206, an automatic positioning assembly, a top rod 211, and an electric clamp. The vision sensor 11 is mounted on the frame 1. Two support columns 201 are connected to the frame 1. A housing 202 is slidably connected to all the support columns 201. Two electric cover plates 203 are mounted on the housing 202. Each electric cover plate 203 consists of a motor and a transparent acrylic plate. The motor output shaft 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 elements I 206, which are springs, are fixedly connected between the rectangular frame 204 and the sliding plate 205. An automatic positioning assembly is connected to the sliding plate 205. A top rod 211 is connected to the automatic positioning assembly. An electric clamp is connected to each support column 201.

[0036] The automatic positioning assembly 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 electric sliders I 208; an electric slider II 210 is fixedly connected to the electric slide rail II 209; and the electric slider II 210 is fixedly connected to the push rod 211.

[0037] The electric clamp 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 bottom inner side 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.

[0038] A rubber strip is provided on the clamp 216 to increase the friction between the clamp 216 and the circuit board 3.

[0039] It also includes a conduit 301 and a branch pipe 302; a conduit 301 is fixedly connected to each support 201; each conduit 301 is fixedly connected to a corresponding fixed box 212; and a branch pipe 302 is fixedly connected to and connected to each conduit 301.

[0040] The external air pump is connected to two conduits 301 in advance, and the two electric covers 203 are initially in the open state. After the circuit board 3 is manually placed into the box 202, the two electric covers 203 are then closed to form a sealed space inside the box 202. When testing the circuit board 3, the existing testing equipment usually only applies pressure to the middle of the circuit board 3 to perform a pressure resistance test. It cannot flexibly adjust the pressure position of the circuit board 3 for multiple circuit boards 3 in the same batch, which leads to incomplete force coverage of the circuit board 3 and thus affects the accuracy of the test results.

[0041] To solve the above problems, after the circuit board 3 is placed inside the housing 202, the circuit board 3 is supported by the upper surfaces of the two fixed boxes 212, and the circuit board 3 is located between the four sliding plates 215. Then, all the electric sliders III 214 are activated and move along one electric slide rail III 213. Each movement of the electric slider III 214 drives one sliding plate 215 to move, and each movement of the sliding plate 215 drives one clamping block 216 to move. This causes the two clamping blocks 216 to move against one side of the circuit board 3 and continue to move. Then, the two clamping blocks 216 move synchronously to push the circuit board 3 to move until the other side of the circuit board 3 abuts against the clamping block 216 fixed on the fixed box 212. Thus, the four clamping blocks 216 work together to clamp and limit the circuit board 3.

[0042] After clamping and limiting the circuit board 3, the wires inside the sliding plate 205 are connected to the external power supply for power supply. Then, according to the program settings, the two electric sliders I 208 are started and each moves along an electric slide rail I 207. The movement of the two electric sliders I 208 together drives the electric slide rail II 209 to move, so that 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 movement of the electric slide rail II 209 drives all connected components to move, thereby driving the top rod 211 to move longitudinally. Then, the electric slider II 210 is started and moves laterally along the electric slide rail II 209, so that the position of the top rod 211 relative to the circuit board 3 can be automatically adjusted according to the program settings. Then, the electric actuator 2 is started. The telescopic part of the electric actuator 2 moves and drives the pressure plate 21 to move downward. The pressure plate 21 moves and abuts against the upper surface of the sliding plate 205 and drives the sliding plate 205 to move downward, thereby compressing all the elastic elements I 206. The movement of the sliding plate 205 drives the... All connected components move downwards, which in turn moves the top rod 211 downwards. The downward movement of the top rod 211 applies pressure to the circuit board 3, and the pressure applied to the circuit board 3 is preset. Then, the vision sensor 11 is activated to detect the circuit board 3. If the circuit board 3 does not break during the pressure test, it means that the circuit board 3 meets the production standards. Conversely, if the circuit board 3 breaks during the pressure test, it means that the circuit board 3 meets the production standards. This allows us to know the compressive strength of the circuit board 3 within the preset pressure range, thus realizing the compressive strength test of the circuit board 3. After the test is completed, the circuit board 3 is removed. After the next circuit board 3 is placed into the housing 202, the position of the top rod 211 relative to the circuit board 3 is adjusted, and the circuit board 3 is pressured again in the same way, and the compressive strength of the circuit board 3 is tested. This allows for flexible adjustment of the pressure position for multiple circuit boards 3 in the same batch, thereby improving the accuracy of the test results.

[0043] Furthermore, due to the influence of the operating environment during actual use, the performance of circuit board 3 may change. Existing testing equipment cannot simulate the actual operating environment of circuit board 3, nor can it test circuit board 3 after performance changes, resulting in significant limitations in testing. To solve the above problems, the operation of the external air pump is controlled to first input hot air into the two conduits 301, and then 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 enclosure 202, thereby changing the temperature environment inside the enclosure 202. Since the enclosure 202 forms a sealed space when testing circuit board 3, circuit board 3 can be quickly subjected to high or low temperature environments. Then, pressure is applied to circuit board 3 in the same manner as above, thereby testing the pressure resistance performance of circuit board 3 under high or low temperature environments, thus reducing the limitations in testing the pressure resistance performance of circuit board 3 and further improving the accuracy of the test results. Example

[0044] Based on Example 1, according to Figure 6 and Figures 8-11 As shown, it also includes a vibration chip removal system; the vibration chip removal system is connected to the housing 202; the vibration chip removal system includes an electric opening and closing plate 2021, elastic element II 217, electric slide rail IV 401, electric slider IV 402, bracket 403, slide rod 404, elastic element III 405, mounting bracket 406, vibration motor 407, and pressure block 408; the lower part of the housing 202 is connected to the electric opening and closing plate 2021, which consists of a motor and a rectangular plate. The motor output shaft rotates to drive the rectangular plate to rotate, and the rectangular plate carries the debris; each slide plate 215 is fixedly connected to the corresponding clamping block 216 with two elastic elements II 217, which are springs; the lower part of the frame 1 is fixedly connected to two electric slide rails IV 401; each electric slide rail IV 401 is slidably connected to... Two electric sliders IV 402; all electric sliders IV 402 on the same electric slide rail IV 401 are fixedly connected to a bracket 403; each bracket 403 has two slide rods 404 fixedly connected; the ends of all slide rods 404 on the same bracket 403 away from the electric slide rail IV 401 are fixedly connected to the housing 202; each slide rod 404 has an elastic element III 405 on its outer side, the elastic element III 405 is a spring, one end of the elastic element III 405 is fixedly connected to the bracket 403, and the other end of the elastic element III 405 is fixedly connected to the housing 202; two mounting brackets 406 are fixedly connected to the lower surface of the housing 202; each mounting bracket 406 has a vibration motor 407 fixedly connected to it; the housing 202 has two slots that mate with the support column 201, and a pressure block 408 is fixedly connected in each slot.

[0045] The bottom inner side of the housing 202 is provided with an inverted trapezoidal groove for guiding the debris conveyed after the circuit board 3 is broken.

[0046] Each branch pipe 302 is equipped with a solenoid valve, and the conduit 301 runs through the entire fixed box 212 and protrudes from the side of the fixed box 212 for blowing air into the box 202 after displacement.

[0047] It also includes a protrusion 2161; each clamping block 216 has a protrusion 2161 fixedly attached to its upper part to cooperate with the corresponding pressing block 408.

[0048] It also includes a dustproof component 409; a dustproof component 409 is fixed between the slide plate 215 connected to the electric slider Ⅲ214 and the corresponding fixed box 212. The dustproof component 409 is an elastic cloth, and another dustproof component 409 is fixed between all slide plates 215 in the same fixed box 212.

[0049] When circuit board 3 breaks during the pressure test, it will produce a lot of fragments and debris. Since the pressure is applied to circuit board 3 at different locations during the test, the location of the breakage will vary. As a result, the fragments and debris generated when circuit board 3 breaks will not be concentrated and will be scattered in all directions. Since the fragments and debris are all inside the enclosure 202, it is necessary to collect and clean the fragments and debris inside the enclosure 202 for subsequent use.

[0050] The peripheral collection box is pre-placed in the designated position. Then, all the electric sliders IV 402 are activated and move forward along the corresponding electric slide rails IV 401 with the front side of the frame 1 as the reference. Each pair of moving electric sliders IV 402 drives a corresponding bracket 403 to move. The movement of the bracket 403 drives the corresponding slide bar 404 to move. All slide bars 404 move synchronously, jointly driving the box 202 to move. To prevent the clamping block 216 from obstructing the movement of the box 202, the pressure block 408 is set to prevent the box 202 from moving forward. When the housing 202 moves, it causes the two pressure blocks 408 to move, which in turn causes the pressure blocks 408 to contact the protrusion 2161 on the clamping block 216 and squeeze the protrusion 2161. This causes the protrusion 2161 to move downward and compress the corresponding elastic element II 217, thereby causing the clamping block 216 to move downward into the corresponding sliding plate 215. This prevents the clamping block 216 from obstructing the movement of the housing 202, allowing the housing 202 to move forward smoothly until it moves away from the support column 201. Figure 10As shown, the two vibration motors 407 are then started, causing the box 202 to vibrate up and down, and all elastic elements Ⅲ 405 to deform adaptively. Since the bottom inner side of the box 202 has an inverted trapezoidal groove, when the box 202 vibrates up and down, the fragments and debris inside the box 202 move to the electric opening and closing plate 2021. The electric opening and closing plate 2021 is then opened, allowing the fragments and debris inside the box 202 to flow out and be collected by an external collection box, thereby cleaning the fragments and debris inside the box 202 for subsequent use.

[0051] Furthermore, since the conduit 301 runs through the entire fixed box 212 and protrudes from the side of the fixed box 212, even after the box 202 is moved, the conduit 301 can still ventilate into the box 202. Then, the external air pump is controlled to supply air into the two conduits 301, and the solenoid valves installed on the two branch pipes 302 are controlled to close, so that the gas can only flow out through the other end of the conduit 301. This allows the gas to be blown into the box 202, thereby blowing away the fragments and debris inside the box 202, reducing the phenomenon of fragments and debris adhering to the inner wall of the box 202, and thus improving the cleaning effect of the box 202.

[0052] It should be noted that the dustproof component 409 enables the sliding plate 215 on the electric slider Ⅲ214 to move, thereby driving the corresponding clamping block 216 to move. The movement of the clamping block 216 causes the dustproof component 409 to deform adaptively, thus shielding the upper part of the fixed box 212 and preventing fragments and debris generated when the circuit board 3 breaks from entering the fixed box 212 and affecting the normal operation of the equipment.
