Description

Technical Field

[0001] The utility model relates to the technical field of SMT patches, in particular to a deviation-correcting device used for the production and processing of SMT patches. Background Art

[0002] SMT is an abbreviation for the series of process steps performed on PCBs. SMT, standing for surface mount technology, is the most popular technology and process in the electronics assembly industry. The basic SMT process generally includes: screen printing, placement, reflow soldering, testing, and repair. With the increasing popularity of automation, placement machines are used to pick up components with suction heads and then install them in fixed locations on the PCB.

[0003] At present, when using a placement machine to place SMT patches on a circuit board, most of them do not have the function of positioning the position of the conveyed circuit board. Since most circuit boards are transported to the inside of the placement machine through a conveyor belt and the placement work is carried out, and since the conveyor belt will produce an offset phenomenon during the process of transporting objects, when the circuit board is being transported, it is easy to cause the conveyed circuit board to deviate on the conveyor belt, which can easily cause the circuit board to tilt after the patch, thereby reducing the quality of the patch.

[0004] Therefore, it is necessary to provide a correction device for SMT patch production and processing to solve the above technical problems. Utility Model Content

[0010] A rotating shaft is rotatably connected to the frame, and a gear 1 is fixedly sleeved on the outer surface of the rotating shaft.

[0011] As a further description of the above technical solution:

[0012] The conveying assembly includes two conveying rollers, both of which are rotatably connected between the two sides of the inner wall of the frame, and a conveyor belt is transmission-connected between the outer surfaces of the two conveying rollers. A driving motor is fixedly mounted on the frame, and the output end of the driving motor is fixedly connected to one end of one of the conveying rollers.

[0013] As a further description of the above technical solution:

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.

[0030] Reference Figure 1-5The utility model provides a correction device for SMT patch production and processing: it includes a frame 1, the frame 1 is rotatably connected to a rotating shaft 12, the outer surface of the rotating shaft 12 is fixedly sleeved with a gear 13, the frame 1 is provided with a controller 21, the top of the frame 1 is fixedly connected to a patch box 2, the top of the patch box 2 is fixedly installed with an electric push rod 3, the bottom of the electric push rod 3 is fixedly installed with a patch mechanism 4, two electric telescopic rods 5 are fixedly installed on the top of the frame 1, the telescopic ends of the two electric telescopic rods 5 are fixedly connected with a positioning plate 6, a number of touch switches 7 are embedded on the positioning plate 6, an adjusting slot 8 is opened on the positioning plate 6, the internal sliding connection of the adjusting slot 8 is connected to two adjusting plates 9, a driving component is provided on the positioning plate 6, and a conveying component and a spacing component are provided on the frame 1.

[0031] The driving component includes a stepper motor 10, which is fixedly mounted on one side of the positioning plate 6. The internal rotation of the adjustment slot 8 is connected to a bidirectional threaded rod 11. The output end of the stepper motor 10 is fixedly connected to one end of the bidirectional threaded rod 11. The bidirectional threaded rod 11 is threadedly connected to the adjustment plate 9. Through the coordinated use of structures such as the frame 1, the patch box 2, the patch mechanism 4, the positioning plate 6, the adjustment plate 9, the conveyor belt 15 and the controller 21, the circuit board can be transported to the inside of the patch box 2, and after abutting with the positioning plate 6, its two sides are limited, thereby avoiding the circuit board from being offset during the transportation process, which causes the patch to tilt, thereby improving the quality of the SMT patch on the circuit board.

[0032] The conveying assembly includes two conveying rollers 14, which are rotatably connected between the two sides of the inner wall of the frame 1. A conveyor belt 15 is transmission-connected between the outer surfaces of the two conveying rollers 14. A transmission mechanism 17 is transmission-connected between the outer surface of one of the conveying rollers 14 and the outer surface of the rotating shaft 12. A drive motor 16 is fixedly mounted on the frame 1, and the output end of the drive motor 16 is fixedly connected to one end of one of the conveying rollers 14.

[0033] The spacing component includes a rotating roller 18, which is rotatably connected to the top of the frame 1. A number of partitions 19 are fixedly connected to the outer surface of the rotating roller 18, and the partitions 19 are movably abutted against the conveyor belt 15. One end of the rotating roller 18 is fixedly connected to gear 2 20, and gear 13 is engaged with gear 2 20. By starting the drive motor 16 to rotate the conveyor belt 15, the rotating roller 18 and the partitions 19 can be rotated synchronously under the cooperation of the transmission structure, the rotating shaft 12, the gear 13 and the gear 2 20, and when relative to the rotation direction of the conveyor belt 15, the spacing of the circuit boards being transported can be adjusted. At the same time, there is no need to use other driving equipment, which reduces the cost of the device and improves the practicality of the device.

[0034] Working principle: When working, the driving motor 16 is started by the controller 21, which makes the conveyor belt 15 rotate. During the rotation process, under the cooperation of the transmission mechanism 17, one of the conveyor rollers 14 drives the rotating shaft 12 and the gear 1 13 to rotate, and the gear 1 13 drives the gear 2 20 meshing with it to rotate, and the gear 2 20 drives the rotating roller 18 and several partitions 19 to rotate. Then, when the solder paste printing on the circuit board is completed and it is transported to the patch box 2 through the conveyor belt 15, the spacing between the circuit boards is adjusted by the several partitions 19 that rotate synchronously and relatively, and after the adjustment is completed, it is transported to the inside of the patch box 2;

[0035] When the circuit board is transported to the inside of the patch box 2, it will first abut against the positioning plate 6 and contact the touch switch 7, so that it transmits a signal to the controller 21 after being touched. The controller 21 that receives the signal starts the stepping motor 10, which drives the bidirectional threaded rod 11 to rotate. Under the cooperation of the adjusting slot 8, the two adjusting plates 9 are moved relative to each other. After the distance between them is reduced, the two sides of the circuit board can be limited, so that the two sides and the front of the circuit board are respectively abutted against the two adjusting plates 9 and the positioning plate 6 to fix its position and prevent it from shifting during the transportation by the conveyor belt 15. The electric push rod 3 can be started to extend its telescopic end to drive the patch mechanism 4 to move down for patch work. After the patch is completed and the patch mechanism 4 is reset, the stepping motor 10 can be started to reverse, release the limit on both sides of the circuit board, and at the same time, the two electric telescopic rods 5 make their telescopic ends extend to drive the positioning plate 6 to move up, so that the circuit board with patch completed can be transported to the next process.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
