Description

Technical Field

[0001] The utility model relates to the technical field of SMT detection equipment, in particular to a detection equipment for SMT processing which is convenient to use. Background Technique

[0002] After the circuit board is produced, it is necessary to detect the surface mount technology (SMT) of the circuit board to ensure the welding quality and assembly quality. However, during the detection process, the sizes of the fixing mechanisms are mostly fixed, which is not convenient for fixing circuit boards of different sizes.

[0003] Based on the above problems, a patent with the publication number of CN213562084U discloses a detection equipment for SMT processing which is convenient to use. By setting a first magnet, a second magnet and a clamping plate, the staff controls the first magnet to work, so that the first spring contracts, and the wedge block drives the two clamping plates to move away from each other through two rollers. When the PCB board moves to a suitable position, the staff controls the first magnet to stop working, so that the clamping plate drives the rubber pad to contact the PCB board and clamp it. The operation is simple, so that the staff can fix PCB boards of different sizes without replacing the fixing mechanism, so as to achieve the purpose of convenient use for the staff.

[0004] However, when implementing the above-mentioned detection equipment for SMT processing which is convenient to use, it is found that it at least has the following problems. The detection method for the PCB board is single-board single detection. After the PCB board is fixed, it is moved under the camera. The camera detects the PCB board and projects it on the display. After manual confirmation, the PCB board is taken out and a new PCB board is put in again. During the detection, the PCB board to be detected cannot be pre-loaded, so the waiting time during the detection is wasted, resulting in the detection efficiency not being improved.

Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment: Please refer to Figures 1 to 5 , a technical solution is provided according to an embodiment of the present invention: A detection device for SMT processing that is easy to use, including: a detection body 1, a transposition platform mechanism, and a rotation mechanism. Among them, a detection camera 2 is installed at the top inside the detection body 1, and a display 3 is installed on one side of the detection body 1. The display 3 is electrically connected to the detection camera 2; the transposition platform mechanism includes a support frame 4, a sliding frame 5, a first sliding table 6, and a second sliding table 7. Slide rails 8 are provided on both sides of the inner wall of the support frame 4 and the outside of the sliding frame 5. Sliders 9 that are slidably matched with the slide rails 8 are provided at the bottoms of the first sliding table 6 and the second sliding table 7. The second sliding table 7 can pass through the bottom of the first sliding table 6; the driving mechanism includes a transmission wheel 10, a belt 11, and a reduction motor 12. The transmission wheel 10 is rotatably connected to the support frame 4. A belt 11 is sleeved between the transmission wheels 10. The reduction motor 12 is fixed on the support frame 4 and drives the transmission wheel 10 to rotate. Clamping members 13 are fixedly provided on the sides of the first sliding table 6 and the second sliding table 7 facing the support frame 4. The belt 11 is divided into an inner part facing the sliding frame 5 and an outer part facing away from the sliding frame 5. The clamping member 13 on the first sliding table 6 clamps and fixes the outer part of the belt 11, and the clamping member 13 on the second sliding table 7 clamps and fixes the inner part of the belt 11.

[0028] For the detection device for SMT processing that is easy to use with the above structure, the reduction motor 12 drives the transmission wheel 10 to rotate forward and backward, and then drives the first sliding table 6 and the second sliding table 7 to slide back and forth on the slide rail 8 through the belt 11. When the PCB board on the first sliding table 6 is transmitted to the bottom of the detection camera 2 for detection, the PCB board to be detected can be placed on the second sliding table 7. After the PCB board on the first sliding table 6 is detected, during the process of the first sliding table 6 being driven by the belt 11 to reset, the PCB board to be detected on the second sliding table 7 is transmitted to the bottom of the detection camera 2 by the belt 11 along the bottom of the first sliding table 6 for detection. This structure can pre-install the PCB board to be detected during the detection process, thereby saving the time for pre-installing the PCB board, and further increasing the detection efficiency of the PCB board.

[0029] In this embodiment, to prevent the PCB board from falling during the process of being driven by the belt 11 to slide on the first sliding table 6 and the second sliding table 7, four L-shaped limiting and supporting members 14 are provided on the tops of the first sliding table 6 and the second sliding table 7. When the PCB board is placed between the four limiting and supporting members 14, the limiting and supporting members 14 can limit the PCB board, thereby preventing the PCB board from falling.

[0030] In this embodiment, since there are many components or soldering on the PCB board, etc., this results in the PCB board being uneven when placed on the first sliding table 6 and the second sliding table 7. It will be affected by the protruding components or soldering, causing the PCB board to tilt, making it difficult for the detection camera 2 to face the PCB board directly, which to a certain extent affects the detection accuracy. To solve the problem of the PCB board, a supporting notch 15 is provided on the top of the supporting member. When the PCB board is placed on the supporting notch 15, there will be a certain gap between the PCB board and the first sliding table 6 or the second sliding table 7, and the substrate of the PCB board is supported by the supporting notch 15 of the supporting member. Furthermore, when the PCB board is placed on the supporting notch 15, the PCB board is in a relatively flat state. During the detection process, the detection camera 2 can better face the PCB board directly.

[0031] In this embodiment, to ensure that the first sliding table 6 and the second sliding table 7 can be placed at the bottom of the detection camera 2 each time, two limiting ejector pins 16 are installed on the support frame 4, and the two limiting ejector pins 16 are respectively directed towards the first sliding table 6 and the second sliding table 7 and abutted against the first sliding table 6 and the second sliding table 7. When the belt 11 drives the first sliding table 6 and the second sliding table 7 to move relative to each other, due to the limiting ejector pins 16, when the first sliding table 6 or the second sliding table 7 moves to the bottom of the detection camera 2, it will be blocked by the limiting ejector pins 16 and cannot move further.

[0032] In this embodiment, during the initial installation of the limiting ejector pins 16, the lengths of the limiting ejector pins 16 need to be adjusted multiple times to ensure that the first sliding table 6 or the second sliding table 7 does not move too much or too little. Therefore, the installation of the limiting ejector pins 16 is rather troublesome. To facilitate the adjustment of the limiting ejector pins 16, the limiting ejector pins 16 are bolted to the mounting block 17, and the mounting block 17 is fixed to the support frame 4. When it is necessary to adjust the limiting ejector pins 16, the limiting ejector pins 16 can be rotated to enter or exit the mounting block 17, thereby facilitating the adjustment of the limiting ejector pins 16.

[0033] In this embodiment, the method of driving the first slide table 6 or the second slide table 7 by the belt 11 is relatively energy-saving. Only one reduction motor 12 is required to drive the first slide table 6 or the second slide table 7 to move back and forth. However, since the belt 11 needs to drive the first slide table 6 or the second slide table 7 to move, although it only drives the PCB board, it is inevitable that the belt will break during long-term use. Therefore, the clamping member 13 includes a bolt 1301 and a clamping plate 1302. The clamping plate 1302 is fixed on the first slide table 6 or the second slide table 7 by the bolt 1301, and the belt 11 is clamped and fixed by the clamping plate 1302. After replacing the belt 11, it can be quickly installed, and the disassembly is relatively simple.

[0034] In this embodiment, to increase the clamping force of the clamping plate 1302 on the belt 11, multiple rows of tooth-shaped protrusions 18 are provided on the side where the clamping plate 1302 clamps the belt 11. The clamping force is increased through the multiple rows of tooth-shaped protrusions 18. To prevent the protruding part of the tooth-shaped protrusions 18 from damaging the belt 11, the protruding part of the stop tooth-shaped protrusions 18 is set to be arc-shaped.

[0035] Working principle: During the debugging stage, the clamping plate 1302 is fixed on the first slide table 6 or the second slide table 7 by the bolt 1301, and the multiple rows of tooth-shaped protrusions 18 of the clamping plate 1302 are abutted against the support frame 4. The clamping plate 1302 and the support frame 4 clamp the belt 11. When the reduction motor 12 drives the belt 11 to move through the transmission wheel 10, the belt 11 can drive the first slide table 6 and the second slide table 7 to move back and forth. At the same time, during the movement of the first slide table 6 and the second slide table 7, observe the positions where the first slide table 6 and the second slide table 7 abut against the limit ejector pin 16, so that the first slide table 6 and the second slide table 7 can be located directly below the detection camera 2. When the moving distance of the first slide table 6 or the second slide table 7 is too much or too little, the limit ejector pin 16 can be rotated, so that the limit ejector pin 16 enters or exits the mounting block 17 through the threaded part, thereby making adjustments.

[0036] In the detection stage, the PCB board to be detected can be placed in the supporting notch 15 of the supporting member of the first sliding table 6. By the forward and reverse rotation of the reduction motor 12, the driving wheel 10 is driven to rotate, and then the belt 11 between the two driving wheels 10 moves. When the reduction motor 12 rotates forward, the belt 11 drives the first sliding table 6 to slide on the slide rail 8 so that the first sliding table 6 moves to the bottom of the detection camera 2. The image of the PCB board to be detected by the detection camera 2 is transmitted to the display 3 for detection. The second sliding table 7 located on the other part of the belt 11 is driven by the belt 11 to the outside. At this time, another PCB board to be detected can be placed in the supporting notch 15 of the supporting member of the second sliding table 7. After the PCB board on the first sliding table 6 is detected, the reduction motor 12 rotates in reverse, and the PCB board on the second sliding table 7 is driven by the belt 11 to the bottom of the detection camera 2 for detection, while the first sliding table 6 is driven by the belt 11 to return to its original position. At this time, the subsequent PCB boards to be detected can be placed on the first sliding table 6 for circulation;

[0037] In the maintenance stage, when the belt 11 breaks during use, the clamping plate 1302 can be separated from the support frame 4 by rotating the bolt 1301, so that the clamping plate 1302 and the support frame 4 do not clamp the belt 11. Then the belt 11 is taken out. How the belt 11 is sleeved and tightened between the two driving wheels 10 is the prior art, so it will not be elaborated here. After the belt 11 is sleeved between the two driving wheels 10, the belt 11 is clamped by the clamping plate 1302 and the support frame, and then the clamping plate 1302 and the support frame 4 are fixed by the bolt 1301 to complete the maintenance.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
