Description

Technical Field

[0001] This invention relates to the field of circuit board testing technology, and in particular to a debugging and testing system for the production of circuit control boards and its usage method. Background Technology

[0002] During the production of circuit control boards, they need to be tested and debugged using testing equipment. The main principle is to connect the test probes on the test module to the circuit board being tested, and then, under the control of the test software, to test each test point on the circuit control board.

[0003] Existing technical solutions still have some shortcomings in the detection process: In the existing technology, when inspecting circuit boards, it is often necessary to manually position and clamp the circuit boards, and then use a bed of needles to complete the inspection of the circuit boards. However, the positioning and clamping of circuit boards often rely on manual labor, which results in the inability to improve the efficiency of circuit board inspection. Existing technologies can only perform single-probe testing on circuit boards, and cannot verify whether the circuit board can be used normally under vibration.

[0004] To address the aforementioned problems, this invention proposes a debugging and testing system for circuit control board production and its usage method. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies that require manual positioning and clamping of circuit boards, making it impossible to verify whether the circuit boards can be used normally under vibration. This invention proposes a debugging and testing system for the production of circuit control boards and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A debugging and testing system for the production of circuit control boards includes a testing table and multiple circuit boards, with a gantry frame welded to the top of the testing table; It also includes two conveyor belts, which are located on the top sides of the testing station, respectively, for transporting the circuit boards; The inspection structure, located on the top inner wall of the gantry, is used to inspect circuit boards located between two conveyor belts; A vibration structure is installed on top of the testing platform and located between two conveyor belts. It is used to detect the use of the circuit board under vibration. The vibration structure is located below the testing structure and cooperates with the testing structure. An adhesive structure is installed on one side of the gantry, above the leftmost conveyor belt, and is used to remove dust and impurities from the top of the circuit board.

[0007] In one possible design, the detection structure includes an electric push rod fixed to the inner wall of the top of the gantry frame by bolts. The output shaft of the electric push rod is fixed to a push plate by bolts. Multiple slide rods slide through the push plate. The bottom ends of the multiple slide rods are fixed to the same needle bed by bolts. The outer wall of the slide rod is fitted with a first spring fixedly connected to the top of the needle bed, and the top end of the first spring is fixedly connected to the bottom of the push plate. The gantry frame is provided with two sets of clamping structures for clamping and fixing the circuit board. The clamping structure includes a second hydraulic cylinder fixedly penetrating one side of the gantry frame. A second piston rod is slidably connected and sealed inside the second hydraulic cylinder. A support frame is welded to one end of the second piston rod. Multiple guide rods are welded to one side of the support frame, and the other ends of the guide rods slidably penetrate the gantry frame. A U-shaped frame is slidably connected to the inner wall of the support frame away from the second piston rod. Multiple second springs are fixedly connected to the top of the U-shaped frame, and the top ends of the second springs are fixedly connected to the top inner wall of the support frame. A connecting pipe is provided at the top of the second hydraulic cylinder. A first hydraulic cylinder is bolted to the top inner wall of the gantry frame. The first hydraulic cylinder has a first piston rod that slides through it in a sealed manner, and the bottom end of the first piston rod is welded to the top of the push plate. The other end of the connecting pipe is connected to the first hydraulic cylinder. The output shaft of the electric push rod drives the needle bed and the push plate to move down. The push plate drives the first piston rod to move down. The hydraulic oil in the first hydraulic cylinder enters the second hydraulic cylinder through the connecting pipe. The second piston rod pushes the support frame to move towards the middle. At this time, the two U-shaped frames can just clamp the circuit board. Due to the cooperation of the two trapezoidal blocks in the U-shaped frames, the circuit board can be neatly clamped. After the circuit board is clamped and fixed, the needle bed performs the test on the circuit board.

[0008] In one possible design, the vibration structure includes a bidirectional lead screw and a rotating shaft rotatably connected within a gantry frame, with one end of the bidirectional lead screw extending rotatably to the outside of the gantry frame. Two movable platforms, threadedly connected to the bidirectional lead screw, are slidably connected to the top of the testing platform. The two movable platforms are located on the positive and negative thread sections of the bidirectional lead screw, respectively. Cams are rotatably connected to the opposite sides of the two movable platforms. One end of the rotating shaft slides through the cams. Two fixed cylinders are welded to both sides of the top of the testing platform. Round rods are slidably connected within each of the four fixed cylinders. Fixed blocks are welded to the top ends of the four round rods. A common support platform is welded to the side of each of the four fixed blocks that is close to each other. Multiple rollers are rotatably connected inside the support platform, and the rollers are used to support and transport the circuit board located between two conveyor belts. Sloping panels are welded to both sides of the bottom of the support platform, and the sloping panels cooperate with cams. A motor drives a rotating shaft to rotate, which in turn drives the cam to rotate. The cam, through the sloping panels, causes the support platform to vibrate up and down reciprocally. The support platform, through a sliding groove, drives the U-shaped frame, circuit board, and needle bed to vibrate up and down, used to test the reliability of the circuit board under mechanical vibration. Furthermore, by rotating a bidirectional lead screw, two moving platforms are controlled to move towards each other. The cooperation between the cams and the sloping panels allows control of the vibration amplitude of the support platform, further testing the reliability of the circuit board under vibration.

[0009] In one possible design, the adhesive structure includes two fixed brackets welded to one side of the gantry frame. Each of the two fixed brackets has a guide groove on its adjacent side. A common sliding shaft is slidably connected between the two guide grooves. A sponge tube is rotatably connected to the outer wall of the sliding shaft. An adhesive tape layer is wrapped around the outer wall of the sponge tube. The interaction between the sponge tube and the adhesive tape layer allows for the removal of dust from the top of the circuit board. Two threaded rods are rotatably connected to one side of the gantry frame via a base. Nut blocks are threaded onto the outer wall of each of the two threaded rods, and these nut blocks are slidably connected to one side of the gantry frame. A first connecting rod is rotatably connected to one side of each of the two nut blocks. The other end is rotatably connected to the sliding shaft; the threaded rod is driven to rotate by the motor, and the threaded rod drives the sponge tube to move along the track of the guide groove through the nut block, the first connecting rod and the sliding shaft. The outer wall of the sponge tube is covered with tape, so when the sponge tube touches the top of the circuit board on the conveyor belt, the sponge tube can roll on the top of the circuit board, sticking the dust and impurities on the top of the circuit board, so as to avoid the dust and impurities affecting the subsequent needle bed inspection of the circuit board. When the sponge tube has finished cleaning, the nut block drives the sponge tube to move upward along the track of the guide groove through the first connecting rod and the sliding shaft. At this time, the sponge tube is above the circuit board, avoiding the sponge tube touching the circuit board and affecting the transport of the circuit board by the conveyor belt.

[0010] In one possible design, multiple rubber blocks are bolted inside the U-shaped frame, and these rubber blocks are used to block the clamped circuit board. A single bidirectional screw rotates through the multiple rubber blocks, and two trapezoidal blocks are threaded onto the outer wall of the bidirectional screw. Both trapezoidal blocks are slidably connected inside the U-shaped frame. When the two U-shaped frames approach each other, the circuit board can be positioned by the cooperation of the trapezoidal blocks and the rubber blocks. In addition, the distance between the two trapezoidal blocks can be adjusted by the rotation of the bidirectional screw, so that the two trapezoidal blocks can clamp and fix circuit boards of different sizes, which facilitates the subsequent accurate testing of the circuit board by the bed of needles.

[0011] In one possible design, the bottom of the U-shaped frame is fixed with multiple sliding blocks by bolts, and the top two sides of the support platform are provided with multiple sliding grooves, and the sliding grooves are slidably engaged with the sliding blocks. When the two U-shaped frames move towards the middle, the sliding blocks extend into the sliding grooves. When the support platform drives the circuit board to vibrate up and down later, the cooperation between the sliding blocks and the sliding grooves can drive the U-shaped frames to vibrate, thereby ensuring the stability of the circuit board when the support platform drives the circuit board to vibrate and preventing the circuit board from being damaged during vibration.

[0012] In one possible design, the bottom of the fixing block contacts the top of the fixing cylinder, and the top of the support platform is on the same horizontal plane as the bottom of the U-shaped frame. In the initial state, the support platform rests on the top of the fixing cylinder under the action of the fixing block. At this time, the support platform and the U-shaped frame cooperate. Then, when the U-shaped frame moves to the middle later, the sliding block and the sliding groove can slide and cooperate. Thus, when vibration occurs later, the support platform and the U-shaped frame are integrated to prevent the circuit board from being damaged during vibration.

[0013] In one possible design, the guide groove is L-shaped to prevent the sponge tube from contacting the top of the circuit board. When the sponge tube finishes cleaning the top of the circuit board, the nut block moves upward and drives the sliding shaft and the sponge tube to move along the trajectory of the guide groove via the first connecting rod. The sliding shaft and the sponge tube move upward a certain distance under the action of the guide groove, so that a gap is formed between the sponge tube and the circuit board, avoiding contact between the sponge tube and the circuit board and affecting the conveyor belt's transport of the circuit board.

[0014] In one possible design, the top of the testing platform has two inclined slots, and the top of the testing platform is slidably connected to two movable seats via slide rails. Each movable seat has a rectangular slot, and a vertical rod is slidably connected within the rectangular slot. The bottom end of the vertical rod extends into the inclined slot and is slidably connected to it. A leveling block is welded to the top of the vertical rod. Two sliding plates are slidably connected to one side of the gantry frame. The top of the sliding plates engages with the bottom of a nut block. Two third springs are fixedly connected to the top of the testing platform, and the top of the third springs is fixedly connected to the bottom of the sliding plates. A second connecting rod is rotatably connected to the side of each sliding plate that is close to it. The bottom ends of the two second connecting rods are rotatably connected to the two movable seats respectively. The nut block pushes the sliding plates downwards and compresses the third springs. The sliding plates, through the second connecting rods, push the movable seats to move. The movable seats push the vertical rod along the trajectory of the inclined slots, allowing the leveling block to just touch the circuit board. The leveling block can level the circuit board, ensuring its neatness and facilitating the subsequent clamping and fixing of the circuit board by the two U-shaped frames.

[0015] This application discloses a method for using a debugging and testing system for manufacturing circuit control boards, comprising the following steps: S1. The left conveyor belt transports the circuit board into the gantry frame. The circuit board rests on the two conveyor belts and is located on top of the rollers. The output shaft of the electric push rod drives the needle bed and push plate to move down. The push plate drives the first piston rod to move down. The hydraulic oil in the first hydraulic cylinder enters the second hydraulic cylinder through the connecting pipe. The second piston rod pushes the support frame to move towards the middle. At this time, the two U-shaped frames can clamp the circuit board. Due to the cooperation of the two trapezoidal blocks in the U-shaped frames, the circuit board can be neatly clamped. In addition, the distance between the two trapezoidal blocks can be adjusted by the rotation of the bidirectional screw, so that the two trapezoidal blocks can clamp and fix circuit boards of different sizes. After the circuit board is clamped and fixed, the needle bed performs the test on the circuit board. S2. When the circuit board is clamped by two U-shaped frames, the sliding block is in perfect cooperation with the sliding groove. The motor drives the rotating shaft to rotate, which in turn drives the cam to rotate. The cam drives the support platform to vibrate up and down through the inclined plate. The support platform drives the U-shaped frame, circuit board and needle bed to vibrate up and down through the sliding groove. This is used to test the reliability of the circuit board under mechanical vibration environment. In addition, by rotating the bidirectional lead screw, the two moving stages are controlled to move towards each other. Furthermore, by cooperating with the inclined plate, the amplitude of the vibration of the support platform can be controlled, which further tests the reliability of the circuit board under vibration environment. S3. When inspecting the circuit board, the motor drives the threaded rod to rotate. The threaded rod drives the sponge cylinder to move along the guide groove track through the nut block, the first connecting rod and the sliding shaft. The outer wall of the sponge cylinder is covered with adhesive tape. Therefore, when the sponge cylinder touches the top of the circuit board on the conveyor belt, the sponge cylinder can roll on the top of the circuit board to stick the dust and impurities on the top of the circuit board, so as to avoid the dust and impurities affecting the subsequent needle bed inspection of the circuit board. When the sponge cylinder has finished cleaning, the nut block drives the sponge cylinder to move upward along the guide groove track through the first connecting rod and the sliding shaft. At this time, the sponge cylinder is above the circuit board, so as to avoid the sponge cylinder touching the circuit board and affecting the conveyor belt's transport of the circuit board. S4. When the nut block moves down to clean the top of the circuit board, the nut block pushes the sliding plate down and squeezes the third spring. The sliding plate pushes the moving seat to move through the second connecting rod. The moving seat pushes the vertical rod to move along the trajectory of the inclined groove. The aligning block can just touch the circuit board. The aligning block can align the circuit board and ensure that the circuit board is in a neat state, which is convenient for the two U-shaped frames to clamp and fix the circuit board later.

[0016] In this invention, multiple rubber blocks are fixed inside the U-shaped frame by bolts. A single bidirectional screw is rotatably threaded through each of the rubber blocks. Two trapezoidal blocks are threaded onto the outer wall of the bidirectional screw, and both trapezoidal blocks are slidably connected inside the U-shaped frame. When the two U-shaped frames approach each other, the circuit board can be positioned by the cooperation of the trapezoidal blocks and the rubber blocks. In addition, the distance between the two trapezoidal blocks can be adjusted by the rotation of the bidirectional screw, so that the two trapezoidal blocks can clamp and fix circuit boards of different sizes, which facilitates the subsequent accurate testing of the circuit board by the needle bed. In this invention, cams are rotatably connected to the two movable stages on opposite sides, and one end of the rotating shaft slides through the cams. Multiple rollers are rotatably connected inside the support stage, and inclined plates are welded to both sides of the bottom of the support stage. The rotating shaft drives the support stage to vibrate up and down reciprocally via the cams, which is used to detect the reliability of the circuit board under mechanical vibration. In addition, by rotating the bidirectional lead screw to control the movement of the two movable stages, the amplitude of the vibration of the support stage can be controlled, further detecting the reliability of the circuit board under vibration. In this invention, the output shaft of the electric push rod is fixed to a push plate by bolts, the second hydraulic cylinder is slidably connected to a support frame by a second piston rod, the top of the second hydraulic cylinder is provided with a connecting pipe, the first piston rod slides through the first hydraulic cylinder, and the other end of the connecting pipe is connected to the first hydraulic cylinder; the output shaft of the electric push rod drives the needle bed and the push plate to move down, the push plate drives the first piston rod to move down, and the second piston rod pushes the support frame to move towards the middle, at which time the two U-shaped frames can just clamp and position the circuit board, and the circuit board can be fixed and tested without manual operation, thus improving the testing efficiency of the circuit board; In this invention, each of the two fixed frames has a guide groove on one side close to each other, and the two guide grooves are slidably connected by the same sliding shaft. The outer walls of the two threaded rods are threaded with nut blocks, and the nut blocks are rotatably connected to the sliding shaft through a first connecting rod. The threaded rods drive the sponge tube to move along the trajectory of the guide groove through the nut blocks and the first connecting rod. The sponge tube can stick to the dust and impurities on the top of the circuit board, avoiding the dust and impurities from affecting the subsequent needle bed inspection of the circuit board. When the sponge tube has finished cleaning, the sponge tube moves upward along the trajectory of the guide groove, and the sponge tube is no longer in contact with the circuit board, avoiding the sponge tube from affecting the conveyor belt's transport of the circuit board.

[0017] In this invention, the circuit board can be automatically transported by the conveyor belt, and the circuit board can be automatically fixed, positioned and clamped as the output shaft of the electric push rod extends, eliminating the need for manual operation and greatly improving the testing efficiency. Furthermore, the circuit board can be driven to vibrate during testing to detect its usage under vibration, making the testing more comprehensive. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1

[0022] Reference Figures 1-8 A debugging and testing system for the production of circuit control boards, which is used in the field of circuit board testing, includes a testing table 1 and multiple circuit boards 3, and a gantry frame 4 is welded to the top of the testing table 1. It also includes two conveyor belts 2, which are located on the top sides of the testing station 1, respectively, for conveying the circuit board 3.

[0023] Reference Figures 2-6The system also includes a detection structure set on the inner wall of the top of the gantry frame 4 for detecting the circuit board 3 located between the two conveyor belts 2. The detection structure includes an electric push rod 5 fixed to the inner wall of the top of the gantry frame 4 by bolts. The output shaft of the electric push rod 5 is fixed to a push plate 6 by bolts. Multiple slide rods 8 slide through the push plate 6. The bottom ends of the multiple slide rods 8 are fixed to the same needle bed 7 by bolts. The outer wall of the slide rod 8 is fitted with a first spring 9 fixedly connected to the top of the needle bed 7, and the top of the first spring 9 is fixedly connected to the bottom of the push plate 6. The gantry frame 4 is provided with two sets of clamping structures for clamping and fixing the circuit board 3. The clamping structure includes a second hydraulic cylinder 12 fixedly penetrating one side of the gantry frame 4. A second piston rod 13 is slidably connected inside the second hydraulic cylinder 12. A support frame 15 is welded to one end of the second piston rod 13. Multiple guide rods 16 are welded to one side of the support frame 15, and the other ends of the guide rods 16 slidably penetrate the gantry frame 4. A U-shaped frame 17 is slidably connected to the inner wall of the support frame 15 away from the second piston rod 13. Multiple second springs 18 are fixedly connected to the top of the U-shaped frame 17, and the top ends of the second springs 18 are fixedly connected to the top inner wall of the support frame 15. A connecting pipe 14 is provided at the top of the second hydraulic cylinder 12. A first hydraulic cylinder 10 is fixed to the top inner wall of the gantry frame 4 by bolts. The inner seal slides through the first piston rod 11, and the bottom end of the first piston rod 11 is welded to the top of the push plate 6. The other end of the connecting pipe 14 is connected to the first hydraulic cylinder 10. The output shaft of the electric push rod 5 drives the needle bed 7 and the push plate 6 to move down. The push plate 6 drives the first piston rod 11 to move down. The hydraulic oil in the first hydraulic cylinder 10 enters the second hydraulic cylinder 12 through the connecting pipe 14. The second piston rod 13 pushes the support frame 15 to move towards the middle. At this time, the two U-shaped frames 17 can just clamp the circuit board 3. Due to the cooperation of the two trapezoidal blocks 20 in the U-shaped frame 17, the circuit board 3 can be neatly clamped. After the circuit board 3 is clamped and fixed, the needle bed 7 completes the test on the circuit board 3.

[0024] Reference Figure 6 Multiple rubber blocks 19 are fixed inside the U-shaped frame 17 by bolts. The rubber blocks 19 are used to block the clamped circuit board 3. The same bidirectional screw 21 is rotatably passed through the multiple rubber blocks 19. Two trapezoidal blocks 20 are threaded on the outer wall of the bidirectional screw 21, and the two trapezoidal blocks 20 are slidably connected inside the U-shaped frame 17. When the two U-shaped frames 17 are close to each other, the circuit board 3 can be positioned by the cooperation of the trapezoidal blocks 20 and the rubber blocks 19. In addition, the distance between the two trapezoidal blocks 20 can be adjusted by the rotation of the bidirectional screw 21, so that the two trapezoidal blocks 20 can clamp and fix circuit boards 3 of different sizes, which is convenient for the subsequent accurate testing of the circuit board 3 by the needle bed 7.

[0025] Reference Figure 2 and Figure 7 The system also includes a vibration structure located on top of the testing platform 1, between two conveyor belts 2, for detecting the use of the circuit board 3 under vibration. The vibration structure is located below the testing structure and cooperates with it. The vibration structure includes a bidirectional lead screw 30 and a rotating shaft 32 rotatably connected within the gantry frame 4. One end of the bidirectional lead screw 30 extends rotatably to the outside of the gantry frame 4. Two movable platforms 29, threadedly connected to the bidirectional lead screw 30, are slidably connected to the top of the testing platform 1. The two movable platforms 29 are located on the positive and negative thread sections of the bidirectional lead screw 30, respectively. Cams 31 are rotatably connected to the opposite sides of the two movable platforms 29. One end of the rotating shaft 32 slides through the cams 31. Two fixed cylinders 23 are welded to both sides of the top of the testing platform 1. Round rods 24 are slidably connected inside each of the four fixed cylinders 23. Fixed blocks 25 are welded to the top of each of the four round rods 24. The fixed blocks 25 are welded to the same support platform 26 on their adjacent sides. Multiple rollers 27 are rotatably connected inside the support platform 26. The rollers 27 are used to support and transport the circuit board 3 located between the two conveyor belts 2. Inclined plates 33 are welded to both sides of the bottom of the support platform 26, and the inclined plates 33 cooperate with the cam 31. The rotating shaft 32 is driven by a motor to rotate, and the rotating shaft 32 drives the cam 31 to rotate. The cam 31 drives the support platform 26 to vibrate up and down through the inclined plates 33. The support platform 26 drives the U-shaped frame 17, the circuit board 3 and the needle bed 7 to vibrate up and down through the sliding groove 28. This is used to detect the reliability of the circuit board 3 under mechanical vibration environment. In addition, the two moving platforms 29 are controlled to move towards each other by rotating the bidirectional lead screw 30. Then, through the cooperation of the cam 31 and the inclined plates 33, the vibration amplitude of the support platform 26 can be controlled, and the reliability of the circuit board 3 under vibration environment can be further detected.

[0026] Reference Figure 6 and Figure 7 The bottom of the U-shaped frame 17 is fixed with multiple sliding blocks 22 by bolts. The top two sides of the support platform 26 are provided with multiple sliding grooves 28, and the sliding grooves 28 slide with the sliding blocks 22. When the two U-shaped frames 17 move towards the middle, the sliding blocks 22 extend into the sliding grooves 28. When the support platform 26 drives the circuit board 3 to vibrate up and down in the later stage, the cooperation between the sliding blocks 22 and the sliding grooves 28 can drive the U-shaped frame 17 to vibrate, thereby ensuring the stability of the circuit board 3 when the support platform 26 drives the circuit board 3 to vibrate and avoiding damage to the circuit board 3 during vibration.

[0027] Reference Figure 6 and Figure 7The bottom of the fixing block 25 contacts the top of the fixing cylinder 23, and the top of the support platform 26 is on the same horizontal plane as the bottom of the U-shaped frame 17. In the initial state, the support platform 26 rests on the top of the fixing cylinder 23 under the action of the fixing block 25. At this time, the support platform 26 cooperates with the U-shaped frame 17. Then, when the U-shaped frame 17 moves to the middle later, the sliding block 22 and the sliding groove 28 can slide and cooperate. In the later vibration, the support platform 26 and the U-shaped frame 17 form a whole, and the circuit board 3 is not damaged during vibration.

[0028] Reference Figure 2 and Figure 8 The system also includes an adhesive structure located on one side of the gantry frame 4, above the leftmost conveyor belt 2, used to remove dust and impurities from the top of the circuit board 3. The adhesive structure includes two fixed brackets 34 welded to one side of the gantry frame 4. Each of the two fixed brackets 34 has a guide groove 35 on its side closest to each other. The two guide grooves 35 are slidably connected to the same sliding shaft 36. A sponge cylinder 37 is rotatably connected to the outer wall of the sliding shaft 36. An adhesive tape layer is wrapped around the outer wall of the sponge cylinder 37. The cooperation between the sponge cylinder 37 and the adhesive tape layer can remove dust from the top of the circuit board 3. Two threaded rods 39 are rotatably connected to one side of the gantry frame 4 via a base. Nut blocks 40 are threaded onto the outer wall of each of the two threaded rods 39, and the nut blocks 40 are slidably connected to one side of the gantry frame 4. A first connecting rod 38 is rotatably connected to one side of each of the two nut blocks 40. The other end of the first connecting rod 38 is rotatably connected to the sliding shaft 36. The threaded rod 39 is driven to rotate by the motor. The threaded rod 39 drives the sponge cylinder 37 to move along the track of the guide groove 35 through the nut block 40, the first connecting rod 38 and the sliding shaft 36. The outer wall of the sponge cylinder 37 is covered with adhesive tape. Therefore, when the sponge cylinder 37 touches the top of the circuit board 3 on the conveyor belt 2, the sponge cylinder 37 can roll on the top of the circuit board 3 to stick the dust and impurities on the top of the circuit board 3, so as to avoid the dust and impurities affecting the subsequent detection of the circuit board 3 by the needle bed 7. When the sponge cylinder 37 has finished cleaning, the nut block 40 drives the sponge cylinder 37 to move upward along the track of the guide groove 35 through the first connecting rod 38 and the sliding shaft 36. At this time, the sponge cylinder 37 is above the circuit board 3, so as to avoid the sponge cylinder 37 touching the circuit board 3 and affecting the transport of the circuit board 3 by the conveyor belt 2.

[0029] Reference Figure 8 The guide groove 35 is L-shaped and is used to release the sponge cylinder 37 from contact with the top of the circuit board 3. When the sponge cylinder 37 finishes cleaning the top of the circuit board 3, the nut block 40 moves upward and drives the sliding shaft 36 and the sponge cylinder 37 to move along the trajectory of the guide groove 35 through the first connecting rod 38. The sliding shaft 36 and the sponge cylinder 37 move upward a certain distance under the action of the guide groove 35, so that a gap is formed between the sponge cylinder 37 and the circuit board 3, so as to avoid the sponge cylinder 37 from contacting the circuit board 3 and affecting the transport of the circuit board 3 by the conveyor belt 2.

[0030] Example 2

[0031] refer to Figures 9-11 Improvements based on Embodiment 1: The top of the testing platform 1 is provided with two inclined grooves 47. The top of the testing platform 1 is slidably connected to two movable seats 44 via slide rails. The movable seats 44 are provided with rectangular grooves 45. A vertical rod 46 is slidably connected in the rectangular grooves 45, and the bottom end of the vertical rod 46 extends into the inclined grooves 47 and is slidably connected to the inclined grooves 47. A regular block 48 is welded to the top of the vertical rod 46. Two sliding plates 41 are slidably connected to one side of the gantry frame 4. The top end of the sliding plate 41 cooperates with the bottom of the nut block 40. Two third springs 42 are fixedly connected to the top of the testing platform 1, and the top end of the third spring 42 is connected to the sliding plate 48. The bottom end of 1 is fixedly connected, and the two sliding plates 41 are rotatably connected to the side of each other. The bottom ends of the two second connecting rods 43 are rotatably connected to the two moving seats 44 respectively. The nut block 40 pushes the sliding plate 41 to move down and squeezes the third spring 42. The sliding plate 41 pushes the moving seat 44 to move through the second connecting rod 43. The moving seat 44 pushes the vertical rod 46 to move along the trajectory of the inclined groove 47. The straightening block 48 can just touch the circuit board 3. The straightening block 48 can straighten the circuit board 3 and ensure that the circuit board 3 is in a neat state, which is convenient for the two U-shaped frames 17 to clamp and fix the circuit board 3 later.

[0032] A method for using a debugging and testing system for circuit control board production includes the following steps: S1. The left conveyor belt 2 transports the circuit board 3 into the gantry 4. The circuit board 3 is placed on the two conveyor belts 2 and is located on top of the roller 27. The output shaft of the electric push rod 5 drives the needle bed 7 and the push plate 6 to move down. The push plate 6 drives the first piston rod 11 to move down. The hydraulic oil in the first hydraulic cylinder 10 enters the second hydraulic cylinder 12 through the connecting pipe 14. The second piston rod 13 pushes the support frame 15 to move towards the middle. At this time, the two U-shaped frames 17 can just clamp the circuit board 3. Due to the cooperation of the two trapezoidal blocks 20 in the U-shaped frame 17, the circuit board 3 can be neatly clamped. In addition, the distance between the two trapezoidal blocks 20 can be adjusted by the rotation of the bidirectional screw 21, so that the two trapezoidal blocks 20 can clamp and fix circuit boards 3 of different sizes. After the circuit board 3 is clamped and fixed, the needle bed 7 performs the test on the circuit board 3. S2. When the circuit board 3 is clamped by the two U-shaped frames 17, the sliding block 22 is just in sync with the sliding groove 28. The motor drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the cam 31 to rotate. The cam 31 drives the support platform 26 to vibrate up and down through the inclined plate 33. The support platform 26 drives the U-shaped frame 17, the circuit board 3 and the needle bed 7 to vibrate up and down through the sliding groove 28. This is used to test the reliability of the circuit board 3 under mechanical vibration. In addition, by rotating the bidirectional lead screw 30, the two moving platforms 29 are controlled to move towards each other. Then, by the cooperation of the cam 31 and the inclined plate 33, the vibration amplitude of the support platform 26 can be controlled, and the reliability of the circuit board 3 under vibration can be further tested. S3. When the circuit board 3 is being inspected, the threaded rod 39 is driven to rotate by the motor. The threaded rod 39 drives the sponge cylinder 37 to move along the track of the guide groove 35 through the nut block 40, the first connecting rod 38 and the sliding shaft 36. The outer wall of the sponge cylinder 37 is covered with adhesive tape. Therefore, when the sponge cylinder 37 touches the top of the circuit board 3 on the conveyor belt 2, the sponge cylinder 37 can roll on the top of the circuit board 3 to stick the dust and impurities on the top of the circuit board 3, so as to avoid the dust and impurities affecting the subsequent inspection of the circuit board 3 by the needle bed 7. When the sponge cylinder 37 has finished cleaning, the nut block 40 drives the sponge cylinder 37 to move upward along the track of the guide groove 35 through the first connecting rod 38 and the sliding shaft 36. At this time, the sponge cylinder 37 is above the circuit board 3, so as to avoid the sponge cylinder 37 touching the circuit board 3 and affecting the transport of the circuit board 3 by the conveyor belt 2. S4. When the nut block 40 moves down to clean the top of the circuit board 3, the nut block 40 pushes the sliding plate 41 down and squeezes the third spring 42. The sliding plate 41 pushes the moving seat 44 to move through the second connecting rod 43. The moving seat 44 pushes the vertical rod 46 to move along the trajectory of the inclined groove 47. The aligning block 48 can just touch the circuit board 3. The aligning block 48 can align the circuit board 3, so that the circuit board 3 is in a neat state, which is convenient for the two U-shaped frames 17 to clamp and fix the circuit board 3 later.
