PCB circuit board splitting cycle detection equipment

Abstract

This invention relates to the field of cyclic testing, and particularly to a PCB board depaneling cyclic testing device. It includes an auxiliary component, on the top of which a feeding component is mounted, and two sets of connecting shells are symmetrically mounted on the output end. The invention utilizes a pressure-relieving and limiting block to compress the center of the PCB board depanel, causing both ends to rise. When subjected to pressure, the limiting block initiates the sliding of a sliding tube within a sleeve, compressing a second compression spring. Upon sensing pressure, the second compression spring applies a rebound force to a pressure sensor to collect pressure values. Furthermore, when both ends of the PCB board depanel tilt upwards, a force is applied to a movable collar, causing the movable collar to rotate on the connecting column according to the pressure applied. This improves the structure's protective effect and pressure collection efficiency during PCB board depaneling testing, thus enhancing the overall cyclic testing effectiveness of the device.

[0007] To address the aforementioned problems, this invention provides a PCB circuit board depaneling and cyclic testing device. It includes an auxiliary component, on the top of which a feeding component is mounted, and two sets of connecting shells are symmetrically mounted on the output end. Two sets of protective components are symmetrically mounted on one side wall of each set of connecting shells. Each set of protective components has a set of compatibility components mounted on it, and a set of testing components is mounted on the outer wall of each set of protective components.

[0008] The protective assembly includes connecting columns and several sets of sleeves.

[0012] Furthermore, the protective assembly also includes a second fixing plate. One end of each set of the second fixing plates is installed on one side wall of one set of connecting shells. Two sets of fixing blocks are symmetrically installed on the corresponding side wall of each set of the second fixing plates. A set of rotating rods is rotatably connected to one side wall of each set of fixing blocks. The two ends of the connecting column are respectively installed on the side walls of the two sets of rotating rods.

[0013] Furthermore, each set of connecting columns has several sets of movable collars movably sleeved at equal intervals on its outer wall. Each set of movable collars has a set of connecting blocks installed on its outer wall. Each set of connecting blocks has one end of two sets of first compression springs symmetrically installed on its inner wall. A sliding plate is installed on the other end of the first compression spring. The outer wall of the sliding plate is slidably connected to the inner wall of the connecting block. Each set of sliding plates has a set of connecting plates installed on one side wall. Each set of connecting plates has a set of first electromagnetic blocks installed on its outer wall. One end of each set of connecting cylinders is installed on one side wall of the sliding plate.

[0014] Furthermore, a set of pressure-reducing limiting blocks are installed on one end of each set of sliding tubes, a set of third fixing plates are installed on one side wall corresponding to each set of second fixing plates, and a set of second electromagnetic blocks are installed on one side wall of each set of third fixing plates. The second electromagnetic blocks are magnetically connected to several sets of first electromagnetic blocks.

[0015] Furthermore, the compatible component includes a third electric slide, one end of each third electric slide is mounted on a side wall corresponding to two sets of second fixed plates, a fourth electric push rod is drivenly connected to the output end of each third electric slide, a fourth fixed plate is mounted on the output end of each fourth electric push rod, and a cavity is formed on each fourth fixed plate.

[0016] Furthermore, a fourth electric slide is installed on one side wall of each group of fourth fixed plates, a fifth electric push rod is connected to the output end of each group of fourth electric slides, and a push tube is installed on the output end of each group of fifth electric push rods.

[0017] Furthermore, the detection assembly includes a sixth electric push rod, one end of which is mounted on the outer wall of one set of sleeves.

[0018] A testing method for a PCB board depaneling cycle testing device, the testing method comprising:

[0019] The feeding assembly is activated to cause the PCB circuit board to separate and transport itself through friction.

[0020] The auxiliary components are activated to perform adsorption and positioning of the PCB circuit board during separation.

[0021] The activation of the compatibility component will cause the protection component to adjust its position.

[0022] The squeezing of the PCB circuit board depaneling center causes the sliding tube to slide within the sleeve.

[0023] Squeeze the second compression spring;

[0024] When the second compression spring senses pressure, it applies a rebound force to the pressure sensor.

[0025] The detection component is activated to perform circuit continuity testing on the PCB circuit board sub-board that is currently being tested.

[0026] The beneficial effects of this invention are:

[0027] 1. When the PCB circuit board is squeezed at the center, the two ends rise, causing a pressure relief and limiting block to be squeezed. When the pressure relief and limiting block is squeezed, it begins to drive the sliding tube to slide within the sleeve. During the sliding process, it begins to squeeze the second compression spring. When the second compression spring senses the pressure, it begins to apply the rebound force to the pressure sensor to collect the pressure value. When the two ends of the PCB circuit board are lifted, the force is applied to the movable collar, causing the movable collar to rotate on the connecting column according to the pressure. This improves the protective effect of the structure for PCB circuit board separation detection and the pressure collection effect; it also improves the effect of the device's cyclic detection.

[0028] 2. Activate one set of second motors to drive the detection structure to rotate and detect the PCB circuit board sub-panel. Because the movable collar rotates smoothly, it drives the sixth electric push rod to adjust its angle, thus placing the PCB circuit board sub-panel and the detection structure on the same horizontal plane, increasing the detection range. Activate the second motor to rotate the output end of the power supply test pen above the PCB circuit board sub-panel, and then activate the fifth electric slide to drive the power supply test pen to perform circuit power supply detection on the PCB circuit board sub-panel being tested. This improves the power supply detection effect while avoiding the PCB circuit board sub-panel from being detected in terms of accuracy.

[0029] 3. When it is necessary to limit the separation of irregular PCB circuit boards, when several sets of first electromagnetic blocks come into contact with second electromagnetic blocks, a specified number of first electromagnetic blocks are energized, thereby making the first electromagnetic blocks and second electromagnetic blocks magnetically connected. When several sets of connecting boards are subsequently removed from the cavity, the specified number of pressure-reducing limit blocks will not reset due to the magnetic connection. Furthermore, when limiting the separation of irregular PCB circuit boards, the fifth electric push rod can be activated to push and drive the specified pressure-reducing limit blocks to shift and adjust. This improves the compatibility and limiting effect of the separation of irregular PCB circuit boards while expanding the detection operation space.

[0030] 4. Activate the third electric push rod to push the placement board upwards. The placement board then moves the PCB circuit board sub-board to the designated height. During its ascent, the friction with the wear-resistant pad layer causes the PCB circuit board sub-board to perform surface cleaning, improving the trimming effect of the PCB circuit board sub-board. Subsequently, activate the second electric slide to move the vacuum suction cup to the designated position. Then, activate the second electric push rod to push the vacuum suction cup down onto the surface of the PCB circuit board sub-board. Then, activate the vacuum pump to evacuate the air in the vacuum chamber, thereby evacuating the air between the vacuum suction cup and the PCB circuit board sub-board, improving the adsorption effect of the structure.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] This invention provides a PCB board depaneling cycle testing device. It includes an auxiliary component 1, such as 1. Figure 2 and Figure 3 As shown, a feeding component 2 is installed on the top of the auxiliary component 1, and two sets of connecting shells 6 are symmetrically installed on the output end. Two sets of protective components 3 are symmetrically installed on one side wall of each set of connecting shells 6. A set of compatible components 4 is installed on each set of protective components 3, and a set of detection components 5 is installed on the outer wall of each set of protective components 3.

[0046] For example, such as Figure 4As shown, the auxiliary component 1 includes a working base plate 101. Two sets of first electric slides 102 are symmetrically installed at the top edge of the working base plate 101. Each set of first electric slides 102 is driven to a set of first electric push rods 103 at its output end. Each set of first electric push rods 103 is driven to a set of first motors 104 at its output end. One end of each set of connecting shells 6 is driven to the output end of one set of first motors 104. A first fixing plate 105 is installed on one side wall of the working base plate 101. A second electric slide 106 is installed on one side wall of the first fixing plate 105. A second electric push rod 107 is driven to the output end of the second electric slide 106. A vacuum box 108 is installed on the output end of the second electric push rod 107. A vacuum suction cup 109 is connected to the bottom of the vacuum box 108. A vacuum pump 110 is installed on the outer wall of the vacuum box 108.

[0047] The second electric slide 106 is activated to move the vacuum suction cup 109 to the designated position. Then, the second electric push rod 107 is activated to push the vacuum suction cup 109 down onto the surface of the PCB circuit board. Then, the vacuum pump 110 is activated to evacuate the air in the vacuum box 108, and in turn, evacuate the air between the vacuum suction cup 109 and the PCB circuit board, thereby improving the adsorption effect of the structure.

[0048] For example, such as Figure 5 As shown, the feeding assembly 2 includes a storage bin 201. The bottom of the storage bin 201 is mounted on the top of the working base plate 101. A third electric push rod 202 is mounted on the inner wall of the bottom of the storage bin 201. A placement plate 203 is mounted on the output end of the third electric push rod 202. A snap-fit ​​shell 204 is mounted on the inner wall of the storage bin 201. A wear-resistant pad 205 is mounted on the inner wall of the snap-fit ​​shell 204.

[0049] Before the PCB circuit board is subjected to cyclic testing, it is placed in the storage box 201. When testing is required, the third electric push rod 202 is activated to push the placement plate 203 upward. The placement plate 203 then drives the PCB circuit board to rise to the specified height. During its rise, the PCB circuit board is subjected to surface cleaning work through friction with the wear-resistant pad 205, which improves the trimming effect of the PCB circuit board.

[0050] For example, such as Figure 6 , Figure 7 and Figure 8As shown, the protective component 3 includes a second fixing plate 301. One end of each set of second fixing plates 301 is installed on one side wall of one set of connecting shells 6. Two sets of fixing blocks 302 are symmetrically installed on the corresponding side wall of each set of second fixing plates 301. A set of rotating rods 303 is rotatably connected to one side wall of each set of fixing blocks 302. A connecting post 304 connects the two sets of rotating rods 303. Several sets of movable collars 305 are equidistantly fitted on the outer wall of each set of connecting posts 304. A set of connecting blocks 306 is installed on the outer wall of each set of movable collars 305. One end of two sets of first compression springs 307 is symmetrically installed on the inner wall of each set of connecting blocks 306. A sliding plate 308 is installed on the other end of the first compression springs 307. The outer wall of the sliding plate 308 is slidably connected to the inner wall of the connecting block 306. A set of connecting plates is installed on one side wall of each set of sliding plates 308. 309. A set of first electromagnetic blocks 310 are installed on the outer wall of each set of connecting plates 309. A set of sleeves 311 are installed on the corresponding side wall of each of the two sets of sliding plates 308. One end of a set of second compression springs 312 is installed on the inner wall of each set of sleeves 311. A set of sliding tubes 313 is installed on the other end of each set of second compression springs 312. Each set of sliding tubes 313 is slidably connected to the inner wall of the sleeves 311. A set of pressure sensors 314 are installed at the junction of each set of second compression springs and sliding tubes 313. A set of pressure-relieving and limiting blocks 315 are installed on one end of each set of sliding tubes 313. A set of third fixing plates 316 are installed on the corresponding side wall of each set of second fixing plates 301. A set of second electromagnetic blocks 317 are installed on the side wall of each set of third fixing plates 316. The second electromagnetic blocks 317 are magnetically connected to several sets of first electromagnetic blocks 310.

[0051] The third electric slide 401 is activated, causing the fourth fixed plate 403 to move towards the connecting plate 309, thereby positioning several sets of connecting plates 309 within the cavity 404. Then, the fourth electric push rod 402 is activated, causing the fourth fixed plate 403 to move closer to the second fixed plate 301, thereby causing several sets of first electromagnetic blocks 310 to contact the second electromagnetic blocks 317. When the several sets of first electromagnetic blocks 310 contact the second electromagnetic blocks 317, they cause the sliding plate 308 to compress the first compression spring 307 within the sleeve block 306. Then, the fourth electric push rod 402 is activated. An electric push rod 103 pushes two sets of connecting shells 6 to move closer to the PCB circuit board sub-board. When the PCB circuit board sub-board is located between several sets of pressure relief and limiting blocks 315, the third electric slide 401 is activated to drive the fourth fixing plate 403 to reset, thereby driving several sets of connecting plates 309 to disengage from the control in the cavity 404. When the first compression spring 307 senses the pressure disappearance, it drives the sliding plate 308 to reset. While resetting, the sliding plate 308 drives several sets of pressure relief and limiting blocks 315 to wrap and limit the PCB circuit board sub-board.

[0052] When it is necessary to limit the separation of irregular PCB circuit boards, when several sets of first electromagnetic blocks 310 and second electromagnetic blocks 317 are brought into contact, a specified number of first electromagnetic blocks 310 are energized, thereby making the first electromagnetic blocks 310 and second electromagnetic blocks 317 magnetically connected. When several sets of connecting plates 309 are subsequently removed from the cavity 404, the specified number of pressure-reducing limit blocks 315 will not reset due to the magnetic connection. Furthermore, when limiting the separation of irregular PCB circuit boards, the fifth electric push rod 406 can be activated to push the push tube 407 to adhere to the surface of one set of socket blocks 306. Subsequently, the fourth electric push rod 402 is activated to move the push tube 407, which in turn moves the specified pressure-reducing limit blocks 315 to adjust their position. This improves the compatibility and limiting effect of the separation of irregular PCB circuit boards while expanding the detection operation space.

[0053] The power supply and withstand pressure tests are initiated. The second electric push rod 107 is activated to push the vacuum suction cup 109 downward, pressing the center of the PCB circuit board sub-panel, causing the PCB circuit board sub-panel to deform. When the two ends of the PCB circuit board sub-panel rise due to the center descent, it presses the pressure relief limit block 315. When the pressure relief limit block 315 is subjected to pressure, it begins to drive the sliding tube 313 to slide within the sleeve 311. During the sliding process, it begins to press the second compression spring 312. When the second compression spring 312 senses the pressure, it begins to apply the rebound force to the pressure sensor 314 to collect the pressure value. When the two ends of the PCB circuit board sub-panel tilt up, it also applies the force to the movable collar 305, causing the movable collar 305 to rotate on the connecting post 304 according to the pressing pressure. This improves the structure's protection effect and pressure collection effect for the PCB circuit board sub-panel testing.

[0054] For example, such as Figure 9 As shown, the compatible component 4 includes a third electric slide 401. One end of each third electric slide 401 is mounted on a corresponding side wall of two sets of second fixed plates 301. A fourth electric push rod 402 is drivenly connected to the output end of each third electric slide 401. A fourth fixed plate 403 is mounted on the output end of each fourth electric push rod 402. A cavity 404 is opened on each fourth fixed plate 403. A fourth electric slide 405 is mounted on a side wall of each fourth fixed plate 403. A fifth electric push rod 406 is drivenly connected to the output end of each fourth electric slide 405. A push tube 407 is mounted on the output end of each fifth electric push rod 406.

[0055] For example, such as Figure 10 As shown, the detection component 5 includes a sixth electric push rod 501. One end of each set of sixth electric push rods 501 is mounted on the outer wall of one set of sleeve cylinders 311. A set of mounting blocks 502 is mounted on the output end of each set of sixth electric push rods 501. A set of fifth electric slides 503 is mounted on one side wall of each set of mounting blocks 502. A set of second motors 504 is driven to the output end of each set of fifth electric slides 503. A set of transmission pipes 505 is driven to the output end of each set of second motors 504. A set of power supply detection pens 506 is mounted on the outer wall of each set of transmission pipes 505. A set of detection structures 507 is mounted on the outer wall of each set of transmission pipes 505.

[0056] When the PCB board is being tested for withstand voltage, the sixth electric push rod 501 is activated to push the detection structure 507 to perform cyclic detection on the surface of the PCB board. To improve the detection angle, one of the second motors 504 can be activated to rotate the detection structure 507. As the movable collar 305 rotates, it will also drive the sixth electric push rod 501 to adjust its angle, thus placing the PCB board and the detection structure on the same horizontal plane, increasing the detection range. While one set of detection structures 507 is performing surface detection, another set of second motors 504 can be activated to rotate the output end of the power supply test pen 506 above the PCB board. Then, the fifth electric slide 503 is activated to drive the power supply test pen 506 to perform circuit power supply detection on the PCB board being tested, improving the power supply detection effect while avoiding the PCB board from avoiding detection accuracy.

[0057] When the pressure at the center of the PCB board separation point causes both ends to rise, it compresses the pressure relief limit block 315. When subjected to pressure, the pressure relief limit block 315 begins to drive the sliding tube 313 to slide within the sleeve 311, and during the sliding process, it begins to compress the second compression spring 312. When the second compression spring 312 senses the pressure, it begins to apply a rebound force to the pressure sensor 314 to collect the pressure value. When both ends of the PCB board separation point are lifted, the force is applied to the movable collar 305, causing the movable collar 305 to rotate on the connecting post 304 according to the pressure. This improves the structure's protective effect and pressure collection effect for PCB board separation detection, and enhances the device's cyclic detection effect.

[0058] One set of second motors 504 is activated to drive the detection structure 507 to rotate and detect the PCB circuit board sub-panel. Because the movable collar 305 rotates smoothly, it drives the sixth electric push rod 501 to adjust its angle, thus placing the PCB circuit board sub-panel and the detection structure on the same horizontal plane, increasing the detection range. The second motor 504 is then activated to rotate the output end of the power supply detection pen 506 above the PCB circuit board sub-panel. The fifth electric slide 503 is then activated to drive the power supply detection pen 506 to perform circuit power supply detection on the PCB circuit board sub-panel being tested. This improves the power supply detection effect while preventing the PCB circuit board sub-panel from avoiding detection accuracy.

[0059] When it is necessary to limit the separation of irregular PCB circuit boards, when several sets of first electromagnetic blocks 310 and second electromagnetic blocks 317 are brought into contact, the specified sets of first electromagnetic blocks 310 are energized, thereby making the sets of first electromagnetic blocks 310 and second electromagnetic blocks 317 magnetically connected. When several sets of connecting plates 309 are subsequently separated from the cavity 404, the specified sets of pressure-reducing limit blocks 315 will not reset due to the magnetic connection. Furthermore, when limiting the separation of irregular PCB circuit boards, the fifth electric push rod 406 can be activated to push and drive the specified pressure-reducing limit blocks 315 to shift and adjust. This improves the compatibility and limiting effect of the separation of irregular PCB circuit boards while expanding the detection operation space.

[0060] The third electric push rod 202 is activated to push the placement plate 203 upward. The placement plate 203 then moves the PCB circuit board sub-panel to a designated height. During its ascent, the friction between the sub-panel and the wear-resistant pad 205 causes the PCB circuit board sub-panel to perform surface cleaning, improving the trimming effect of the PCB circuit board sub-panel. Subsequently, the second electric slide 106 is activated to move the vacuum suction cup 109 to a designated position. Then, the second electric push rod 107 is activated to push the vacuum suction cup 109 down onto the surface of the PCB circuit board sub-panel. Then, the vacuum pump 110 is activated to evacuate the air in the vacuum box 108, thereby evacuating the air between the vacuum suction cup 109 and the PCB circuit board sub-panel, improving the adsorption effect of the structure.

[0061] Based on the aforementioned PCB board depaneling cycle testing equipment, this embodiment of the invention also proposes a testing method for the PCB board depaneling cycle testing equipment. For example, the testing method includes:

[0062] Place the PCB circuit board into the storage box, activate the third electric push rod to push the placement board up, and the placement board causes the PCB circuit board to rub against the wear-resistant pad layer.

[0063] Start the second electric slide to move the vacuum chuck to the designated position, and then start the second electric push rod to push the vacuum chuck down onto the surface of the PCB circuit board.

[0064] Start the vacuum pump to evacuate the air from the vacuum chamber, and then evacuate the air between the vacuum suction cup and the PCB circuit board.

[0065] The third electric slide is activated to move the fourth fixed plate toward the connecting plate, so that several sets of connecting plates are located in the cavity;

[0066] The fourth electric push rod is activated to move the fourth fixed plate closer to the second fixed plate, which in turn causes several sets of first electromagnetic blocks to come into contact with the second electromagnetic blocks;

[0067] When the first electromagnetic block comes into contact with the second electromagnetic block, it causes the sliding plate to squeeze the first compression spring in the sleeve block, and activates the first electric push rod to push the two sets of connecting shells to move closer to the PCB circuit board.

[0068] When the PCB circuit board is separated between several sets of pressure limiting blocks, the third electric slide is activated to drive the fourth fixed plate to reset.

[0069] After the first compression spring senses the pressure disappearing, it drives the sliding plate to reset, and then drives several sets of pressure relief limit blocks to wrap and limit the PCB circuit board.

[0070] When several groups of first electromagnetic blocks come into contact with second electromagnetic blocks, energize several designated groups of first electromagnetic blocks, so that several groups of first electromagnetic blocks and second electromagnetic blocks are magnetically connected.

[0071] When several sets of connecting plates detach from the cavity, the magnetic connection prevents the designated sets of pressure-relieving limit blocks from resetting.

[0072] When separating irregular PCB circuit boards, the fifth electric push rod can be activated to push the push tube to fit against the surface of one of the socket blocks;

[0073] The fourth electric push rod is activated to move the push tube, which in turn moves the designated pressure relief limit block for adjustment.

[0074] The second electric push rod is activated to push the vacuum suction cup down and squeeze the center of the PCB circuit board separator, causing the PCB circuit board separator to begin to deform.

[0075] When the center of the PCB board descends, the two ends rise and squeeze the pressure relief block. When the pressure relief block is squeezed, it begins to drive the sliding tube to slide inside the sleeve.

[0076] During the sliding process, the second compression spring is squeezed, and when the second compression spring senses the pressure, it begins to exert a rebound force on the pressure sensor.

[0077] When the two ends of the PCB board are tilted up, the force is applied to the movable collar, causing the movable collar to rotate on the connecting post according to the pressure.

[0078] The sixth electric push rod is activated to push the detection structure to perform cyclic detection on the surface of the PCB circuit board. One of the second motors is activated to drive the detection structure to rotate.

[0079] When the movable collar rotates, it drives the sixth electric push rod to adjust the angle, so that the PCB circuit board separation and the detection structure are on the same horizontal plane.

[0080] The second motor is started to rotate the output end of the power supply test pen to the top of the PCB circuit board sub-board. Then the fifth electric slide is started to drive the power supply test pen to perform circuit power supply test on the PCB circuit board sub-board that is being tested.

[0081] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
