Description

Technical Field

[0001] The present invention relates to the technical field of detection, and in particular to an anti-damage detection tool for integrated circuit boards. Background Art

[0002] Circuit board testing is a key step in ensuring the quality and reliability of electronic products. Through testing, it can be verified whether the circuit board meets the design specifications and manufacturing standards to ensure that it can achieve the expected functions. Testing can also detect defects in the manufacturing process and ensure its reliability in actual applications.

[0003] However, in the prior art, there are two types of circuit board inspection. One is to manually place the circuit board on the detector and control the telescopic device so that the detector can inspect the circuit board. For double-sided circuit boards, the circuit board needs to be manually reversed continuously. However, in this method, since the circuit board is directly placed on a plane for inspection, the inspector may damage the electronic devices due to excessive force. Components such as chips, capacitors, and resistors may break or fall off due to force. Secondly, the speed of manual inspection often cannot keep up with the speed of the production line, resulting in low inspection efficiency and failure to meet the needs of large-scale production. In addition, the accuracy of manual inspection is affected by the subjective judgment and fatigue of the inspector, which may lead to missed inspections or misjudgments. The other is automatic, in which the circuit board is continuously placed in the detector for fixing, and then transported by a conveyor belt for continuous inspection. However, for double-sided circuit boards, since both sides need to be inspected, and the existing equipment cannot be inspected from both sides, it needs to be manually disassembled or reversed and placed on another detector. This method is very troublesome, resulting in errors by the inspectors and easy damage to the circuit board.

[0004] Therefore, an anti-damage detection tool for integrated circuit boards is proposed, which can automatically reverse and disassemble and automatically detect double sides. Summary of the invention

[0017] Beneficial effects of the present invention:

[0018] 1. The installer drives multiple placement frames to move intermittently, while the limiting strips and square blocks outside the placement frames stabilize the circuit boards, which can quickly and continuously detect circuit boards, improve the efficiency of the production line, and shorten the production cycle. At the same time, the placement frames are used with gears and one-way transmission parts to automatically reverse the circuit boards, thereby performing double-sided inspection and reducing manual intervention. Automated inspection reduces manual operations, reduces the risk of human errors, and improves the accuracy of inspection. It can accurately detect defects on circuit boards, including tiny poor solder joints, broken lines, etc., to ensure product quality, and can effectively enhance the consistency of inspection.

[0019] 2. Using the telescopic device as the drive and a single control part makes the operation more intuitive and simple, reducing the operator's learning time and training costs. The operator can complete the inspection task more efficiently by quickly switching and setting the inspection parameters. At the same time, centralized control reduces the risk of misoperation and helps to achieve system integration, making the coordination between the inspection of the inspection part and the reversal of the one-way transmission part smoother, making equipment maintenance easier, and further ensuring the consistency of the inspection parameters and improving the accuracy of the inspection results.

[0020] 3. The top and bottom of the circuit board are limited by the cooperation of the limiting strips and the square sleeve blocks. When the placement frame drives the limiting strips and the square sleeve blocks to move, the blocking rods and the magnetic rods are used to achieve reversal and unlocking. The structure is relatively simple and does not require expensive electronic equipment and software, thereby reducing equipment costs. At the same time, it makes maintenance and repair work relatively easy, reduces maintenance costs, can be quickly adjusted according to circuit boards of different shapes, has strong adaptability, adapts to changes in the production process, has good stability and reliability, and improves the accuracy of the detection process.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Reference Figure 1-10 , as an embodiment of the present invention, provides an integrated circuit board anti-damage detection tool, including an installer 1, and also includes a telescope 2 fixedly connected to one side of the installer 1, a connecting rod 3 fixedly connected to the output end of the telescope 2, and two detection pieces 4 respectively fixedly connected to the two ends of the connecting rod 3, and two support frames 5 are provided and fixedly connected to one side of the installer 1, and a plurality of placement frames 6 are equidistantly arranged and connected to the inside of the installer 1, and the detection pieces 4 are slidably connected to the outside of the corresponding support frames 5.

[0035] The top and bottom of one side of the placement frame 6 are rotatably connected with multiple square sleeve blocks 8, and the multiple square sleeve blocks 8 are symmetrical about the central axis of the placement frame 6. The interiors of the multiple square sleeve blocks 8 are slidably connected with limiting strips 7. The middle part of the installer 1 is rotatably connected with two one-way transmission parts 9. The interior of the placement frame 6 is fixedly connected with an inner mold 10. The inner mold 10 is an existing mold that can limit the surrounding of the circuit board and can be adjusted according to the shape of different circuit boards. The right side of the placement frame 6 is sleeved on the inside of the connecting part 11, and the connecting part 11 is fixedly connected to the installer 1. The outer side of the left side of the placement frame 6 is rotatably connected with a pulley 12, and a gear 21 is provided on the outside of the telescope 2. The gear 21 is meshed with two one-way transmission parts 9. One end of the one-way transmission part 9 is a protrusion 901. When the protrusion 901 is located inside the placement frame 6, the telescope 2 causes the placement frame 6 to rotate 180 degrees through the one-way transmission part 9 to achieve automatic flipping, reduce the chance of direct contact between the operator and the circuit board, and reduce the risk of circuit board loss.

[0036] Reference Figure 1-9 The detection member 4 is divided into a head detector 41 and a tail detector 42 to detect both sides of the circuit board. A driving motor 101 is arranged on the outside of the installer 1, a slide groove 102 is opened on one side of the inside of the installer 1, a driving belt 103 is sleeved inside the installer 1, the output end of the driving motor 101 is connected to the driving belt 103, the connecting member 11 is fixedly connected to the driving belt 103, a plurality of blocking rods 104 and magnetic rods 105 are symmetrically arranged on the top of the inner side of the installer 1, and the pulley 12 is located inside the slide groove 102.

[0037] Specifically, when the driving belt 103 is driven by the driving motor 101, the driving belt 103 will drive the connecting member 11 to move, and one side of the placement frame 6 is connected to the connecting member 11, so that when the connecting member 11 moves intermittently, the placement frame 6 will also move synchronously, and the pulley 12 on the other side of the placement frame 6 will move inside the slide groove 102.

[0038] Reference Figure 1-7A rotating shaft 61 is arranged on the right side of the placement frame 6, and the rotating shaft 61 is rotatably connected to the inside of the connecting member 11. At the same time, the rotating shaft 61 and the connecting member 11 are subjected to high friction treatment. A groove shaft 62 is arranged on the left side of the placement frame 6, and the pulley 12 is rotatably connected to the outside of the groove shaft 62. The pulley 12 is used to prevent the placement frame 6 from offset rotation when moving with the connecting member 11, so as to ensure that the angle of the placement frame 6 remains unchanged without being subjected to external force. A plurality of limit members 63 are symmetrically arranged on the top and bottom of one side of the placement frame 6, and the limit member 63 is always located on one side of the square sleeve block 8.

[0039] Reference Figure 2-9 When the placement frame 6 is located below the tail detector 42, the limit piece 63 is located between the square sleeve block 8 and the magnetic rod 105, and one side of the limit piece 63 will fit with the magnetic rod 105, so that the limit piece 63 is adsorbed by the magnetic rod 105, and the limit piece 63 is used to limit the square sleeve block 8, so that the number and position of the limit piece 63 and the square sleeve block 8 correspond one to one, and the number of magnetic rods 105 is equal to the number of the limit pieces 63 at the top of the placement frame 6, that is, four limit pieces 63 are provided, and two limit pieces 63 at the top of the placement frame 6 are provided, then the number of magnetic rods 105 is also two.

[0040] Reference Figure 2-6 A mounting shaft 64 and a torsion spring 65 are provided at the top and bottom of one side of the placement frame 6. The square sleeve block 8 is rotatably connected to the outside of the mounting shaft 64. The torsion spring 65 is connected between the square sleeve block 8 and the mounting shaft 64. The mounting shaft 64 supports the square sleeve block 8, and the square sleeve block 8 can rotate outside the mounting shaft 64.

[0041] The limiting strip 7 includes a C-shaped plate 71 slidably connected to the inside of the square sleeve block 8, and a return spring 72 connected between the square sleeve block 8 and the C-shaped plate 71. Two return springs 72 are provided, and the C-shaped plate 71 is used to support the edges of the circuit board at the upper and lower positions. Usually, the edge area of ​​the circuit board needs to be perforated to cooperate with the installation, and it is a flat area. At the same time, when the upper detection member 4 is pressed down, the circuit board is pressed downward to squeeze the C-shaped plate 71, so that the C-shaped plate 71 compresses the return spring 72, effectively avoiding damage to the circuit board. When adjusting for a specific type of circuit board, it is only necessary to replace the C-shaped plate 71 of different sizes, that is, the contact area between the C-shaped plate 71 and the circuit board and the length of the C-shaped plate 71, to cope with different products.

[0042] Reference Figure 1-8 The outer portion of the square sleeve block 8 near the blocking rod 104 is an outer arc surface 81 , the bottom of the square sleeve block 8 near the limiting member 63 is an inner arc surface 82 , and a circular groove 83 is provided on the side of the square sleeve block 8 near the limiting member 63 .

[0043] Specifically, the blocking rod 104 can squeeze the outer arc surface 81 of the square sleeve block 8, so that the square sleeve block 8 rotates after being blocked, and the square sleeve block 8 uses the inner arc surface 82 to squeeze the limit member 63 when rotating, so that the internal structure of the limit member 63 slides, and when the limit member 63 coincides with the circular groove 83, the limit member 63 will limit the circular groove 83 to ensure that the C-shaped plate 71 stably supports the circuit board.

[0044] Reference Figure 1-10 The blocking rod 104 is located near the front detector 41 , and the magnetic rod 105 is located near the rear detector 42 . The blocking rod 104 is used to squeeze one side of the square sleeve block 8 .

[0045] Reference Figure 1-10 The limiting member 63 includes a mounting block 631 fixedly connected to the top of the placing frame 6, a weak spring 632 arranged inside the mounting block 631, and an arc-shaped protrusion 633 slidably connected inside the mounting block 631. The weak spring 632 is connected between the mounting block 631 and the arc-shaped protrusion 633. When the magnetic rod 105 contacts the arc-shaped protrusion 633, the arc-shaped protrusion 633 slides, so that the arc-shaped protrusion 633 moves out of the interior of the square sleeve block 8, wherein the mounting block 631 is made of non-metallic material.

[0046] Reference Figure 1-10 A support block 106 is provided on the outside of the installer 1, and the one-way transmission member 9 includes a spur gear 91 rotatably connected to the top of the support block 106, an arc claw 92 fixedly connected to one side of the spur gear 91, a linkage shaft 93 rotatably connected to the inside of the installer 1, and a plurality of hook claws 94 arranged at equal angles and rotatably connected to the inside of the linkage shaft 93, and the arc claw 92 is located inside the linkage shaft 93 and fits with the hook claw 94.

[0047] Specifically, the hook claw 94 is composed of an arc hook and three springs. The outside of the arc claw 92 is a plurality of arc-shaped claws, and the arc claw 92 has two rotation directions. In one rotation direction, the arc surface of the arc claw will squeeze the hook claw 94, and the arc hook will squeeze the spring to contract, while in the other direction, the arc claw outside the arc claw 92 will engage with the arc hook of the hook claw 94, thereby realizing one-way drive, so that the placement frame 6 can rotate 180 degrees in two positions to complete the reset.

[0048] The working principle of the present invention is as follows: the circuit board is placed inside the inner mold 10, and the bottom of the circuit board will be supported by the C-shaped plate 71. At this time, the driving motor 101 will drive the driving belt 103 to move intermittently. When the driving belt 103 moves intermittently, it will drive the connecting member 11 to move. When the connecting member 11 moves, it will drive the rotating shaft 61 to move synchronously. When the rotating shaft 61 moves, it will drive the placement frame 6 to move synchronously. When the placement frame 6 moves, it will drive the external components to move. When the groove shaft 62 moves with the placement frame 6, the pulley 12 outside the groove shaft 62 will move inside the slide groove 102. At this time, there are three placement frames 6, which will be located below the head detector 41 and the tail detector 42, and between the head detector 41 and the tail detector 42, respectively. There is also a placement frame 6, which is located below the placement frame 6 between the head detector 41 and the tail detector 42. The positions of the limiting strips 7 and the square sleeve blocks 8 of these two placement frames 6 are opposite. , but the groove shaft 62 on one side of both is inserted with a protrusion 901. At this time, the telescopic device 2 drives the bar gear 21 and the connecting rod 3 to move downward, and the connecting rod 3 drives the front detector 41 and the rear detector 42 to slide downward on the outside of the support frame 5. The front detector 41 and the rear detector 42 detect the circuit board below, and the bar gear 21 drives the two spur gears 91 to rotate. When the spur gear 91 rotates, it drives the arc claw 92 to rotate synchronously. When the arc claw 92 rotates forward, it engages with multiple hook claws 94, so that the hook claw 94 drives the linkage shaft 93 to rotate. When the linkage shaft 93 rotates, the protrusion 901 drives the connected groove shaft 62 to rotate, so that the upper and lower placement frames 6 drive the circuit board to rotate 180 degrees, thereby switching to the other side. The overall positions of the square sleeve blocks 8 and the limiting strips 7 outside the two placement frames 6 are also changed synchronously. At this time, the placement frame 6 located at the bottom can be regarded as rotating 360 degrees, thereby completing the rotation reset;

[0049] After the detection is completed, the telescopic device 2 drives the connecting rod 3 to move upward, and then the driving motor 101 drives the driving belt 103 to move intermittently. At this time, multiple placement frames 6 will move synchronously, and when the placement frame 6 located below the first detector 41 continues to move, the outer arc surface 81 of the square sleeve block 8 will be blocked by the blocking rod 104, and the square sleeve block 8 will then rotate ninety degrees, while the torsion spring 65 is rotated and compressed. When the square sleeve block 8 rotates ninety degrees, the C-type plate 71 and the reset spring 72 also rotate with the square sleeve block 8, so that the C-type plate 71 fits the upper edge of the circuit board, and the inner arc surface 82 of the square sleeve block 8 squeezes the arc convex strip 633, so that the arc convex strip 633 translates inside the mounting block 631, and the arc convex strip 633 stretches the weak spring 632. When the square sleeve block 8 rotates 90 degrees, the arc convex strip 633 coincides with the circular groove 83 of the square sleeve block 8, and the weak spring 632 rebounds to make the arc convex strip 633 enter the interior of the circular groove 83, thereby fixing the square sleeve block 8. At this time, the square sleeve at the top and bottom of the placement frame 6 The block 8 is parallel to the circuit board, and the corresponding C-shaped plate 71 will limit the upper and lower edges of the circuit board. At the same time, the placement frame 6 located below the first detector 41 will reach between the first detector 41 and the tail detector 42, and the protrusion 901 will enter the pulley 12 on one side of the placement frame 6. Then, when the placement frame 6 is driven to drive the circuit board to rotate, the circuit board will not fall. The placement frame 6 under the tail detector 42 will also move. At this time, the arc convex strip 633 set in the placement frame 6 will be attracted by the magnetic rod 105, so that the arc convex strip 633 leaves the inside of the circular groove 83, and the circular groove 83 loses the limiting torsion spring 65 to rotate, so that the circular groove 83 rotates ninety degrees, and the C-shaped plate 71 also rotates accordingly and no longer limits the circuit board. At this time, the circuit board can be taken out, and when the telescopic device 2 drives the bar gear 21 to move back, the bar gear 21 will still drive the spur gear 91 and the arc claw 92 to rotate, but at this time the arc claw 92 will squeeze the arc surface outside the hook claw 94, so that the hook claw 94 cannot drive the linkage shaft 93 to transmit to the spur gear 91, and thus the placement frame 6 will not rotate.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
