[0002] In today's rapidly developing electronics manufacturing industry, testing printed circuit boards (PCBAs) is crucial for ensuring product quality. However, existing PCB testing technologies, particularly traditional manual testing or single-track, single-station ICT testers, still have numerous limitations. These traditional testers often suffer from low testing efficiency, only able to test a single PCB at a time, and unable to meet the demands of large-scale production. Furthermore, they often require extensive manual intervention, requiring manual operation step by step from PCB placement, testing, and collection. This not only increases labor costs but also easily leads to testing errors due to human error.

[0003] Therefore, it is necessary to design a dual-track, dual-station ICT multifunctional integrated testing machine that is practical and efficient. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution: a dual-track, dual-station ICT multifunctional integrated testing machine, comprising a workbench 1, an intermittent mechanism connected to the working surface of the workbench 1, a conveyor belt 26 connected to one side of the intermittent mechanism, a fixing mechanism connected to the working surface of the workbench 1, a circuit board placed on the conveyor belt 26, the fixing mechanism corresponding to the circuit board, a limiting mechanism connected to the top of the workbench 1, a first cylinder 5 fixedly connected to the top of the workbench 1, a first piston rod 51 connected to the output end of the first cylinder 5, a square frame 52 fixedly connected to one side of the first piston rod 51, a needle plate 53 connected to the bottom of the square frame 52, the needle plate 53 corresponding to the circuit board; when the staff prepares to test the circuit board, they first place the circuit boards to be tested on the conveyor belt 26 in sequence. This conveyor belt 26 is responsible for smoothly transporting the circuit boards from the input end to the test station and sending them out after the test is completed. Subsequently, the staff activates the intermittent mechanism, causing the conveyor belt 26 to start operating intermittently, thus ensuring that the circuit boards are transported one by one and in an orderly manner to the designated positions.

[0027] When the circuit board is conveyed under needle plate 53, the staff will preemptively operate the stop mechanism, causing it to descend and block the circuit board, preventing it from moving further. Simultaneously, the intermittent mechanism will also stop operating, ensuring that the circuit board remains under needle plate 53. At this point, the fixing mechanism is activated, clamping both circuit boards simultaneously, providing the necessary support and ensuring the stability of the circuit boards during testing.

[0028] Next, the staff will start the first cylinder 5, and the first piston rod 51 at its output end will drop, driving the needle plate 53 to accurately test the circuit board. After the test is completed, the limit mechanism will move upward to release the obstruction to the circuit board, and the fixing mechanism will also loosen the clamping of the circuit board. Subsequently, the intermittent mechanism will start again, and continue to move forward with the circuit board that has completed the test, and send it out of the test area to prepare for the clamping and testing of the next circuit board to be tested. By providing a fixing mechanism, the circuit board is stably clamped to prevent it from displacement or shaking during the test, further improving the accuracy and stability of the test. Through the intermittent mechanism, conveyor belt 26, fixing mechanism, and limit mechanism, the automation of circuit board testing is realized. The relevant personnel only need to put in and take out the circuit board, which improves the test efficiency, reduces manual intervention, and reduces labor costs.

[0029] The intermittent mechanism includes a first motor 2, which is fixedly connected to the working surface of the workbench 1, and the output end of the first motor 2 is fixedly connected to a first rotating shaft 21, one side of the first rotating shaft 21 is fixedly connected to a first gear 22, one side of the first gear 22 is meshed with a second gear 23, and one side of the second gear 23 is fixedly connected to a long rod 24, and the top of the workbench 1 is fixedly connected to a plurality of support blocks 11, and the support blocks 11 and the long rod 24 are rotatably connected, and the outer side of the long rod 24 is fixedly connected to two rollers 25, and the roller 25 is connected to the conveyor belt 26; when the staff turns on the first motor 2, the first rotating shaft 21 at the output end rotates, driving the first gear 22 fixedly connected thereto to rotate, and the rotation of the first gear 22 drives the second gear 23 to rotate, so that the long rod 24 rotates inside the support block 11, driving the two rollers 25 to rotate, and the other end also has a corresponding roller 25, and the roller 25 at one end rotates, driving the conveyor belt 26 to rotate, and the roller 25 at the other end also rotates, and the whole starts to run. By providing a rotating mechanism, the two conveyor belts 26 can be rotated at the same time, and the circuit boards can be transported at the same time, thereby ensuring the normal operation of the device.

[0030] The first gear 22 is an incomplete gear; the first gear 22 is a half gear, that is, the first gear 22 has only half of the teeth. When the half with teeth rotates to rotate with the second gear 23, it rotates with the second gear 23, and when the half without teeth rotates to the side of the second gear 23, it cannot engage at this time. The first gear 22 still rotates, but cannot rotate with the second gear 23, that is, the conveyor belt 26 stops conveying, and the circuit board can be inspected when it stops. By providing a half gear, the circuit board can be continuously conveyed and inspected without stopping the machine, thereby improving work efficiency.

[0031] The fixing mechanism includes a double-headed motor 3, which is fixedly connected to the work surface of the workbench 1. The two output ends of the double-headed motor 3 are fixedly connected to a second rotating shaft 31. Two clamping blocks 32 are connected to the outer sides of the second rotating shaft 31. The top of the workbench 1 is fixedly connected to a baffle 12, which corresponds to the clamping blocks 32. When the staff turns on the double-headed motor 3, the second rotating shafts 31 at both output ends begin to rotate, and as they rotate, they move the two clamping blocks 32 closer or farther away from each other, thereby clamping and releasing two circuit boards simultaneously. The provision of the fixing mechanism ensures stability during the inspection process.

[0032] A thread is provided on the outer side of the second rotating shaft 31, and the clamping block 32 and the second rotating shaft 31 are threadedly connected; because the clamping block 32 and the second rotating shaft 31 are threadedly connected, the rotation of the second rotating shaft 31 will cause the clamping block 32 to rotate and move, but the baffles 12 on both sides of the clamping block 32 limit the rotation of the clamping block 32, so the clamping block 32 can only move, thereby achieving clamping and loosening.

[0033] The thread of the second rotating shaft 31 has two sections, and the two threads are in opposite directions; the outer sides of the two second rotating shafts 31 each have two sections of threads, and the two threads are in opposite directions. One clamping block 32 is on one thread, that is, the two threads corresponding to the two clamping blocks 32 are in opposite directions. Therefore, when the thread rotates, the two clamping blocks 32 will move closer to or away from each other.

[0034] The clamping block 32 is in the shape of an "F", and rubber is provided inside the clamping block 32; when the two clamping blocks 32 are close to each other and clamp the circuit board, the circuit board is just stuck in the top depression of the F, and the lower end of the depression of the F provides a certain support force for the circuit board. The inside of the depression of the F is connected to rubber, which can protect the circuit board and prevent damage to the circuit board when clamping.

[0035] The limiting mechanism includes a second cylinder 4, which is fixedly connected to the top of the workbench 1. The output end of the second cylinder 4 is connected to a second piston rod 41. One side of the second piston rod 41 is fixedly connected to a limiting plate 42, and the limiting plate 42 corresponds to the circuit board; when the staff opens the second cylinder 4, the second piston rod 41 at the output end moves downward, moving the limiting plate 42 downward, and the limiting plate 42 moves to touch the conveyor belt 26. The conveyed circuit board stops when it is transported to the limiting plate 42. The limiting plate 42 is mainly used to make the position of the circuit board more accurate, so that the detection is more accurate.

[0036] The needle plate 53 and the square frame 52 are connected by threads; thus, the needle plate 53 can be disassembled and rotated, which is convenient for the staff to replace.

[0037] A plurality of positioning blocks 27 are fixedly connected to the conveyor belt 26, and the spacing between the plurality of positioning blocks 27 is equal; the positioning blocks 27 first roughly determine the position of each circuit board, and at the same time, when the circuit board reaches the limit plate 42, a certain thrust can be exerted on the circuit board, so that the circuit board fits in that position, and the position is more accurate.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
