[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] like Figure 1-Figure 4 As shown, a processing layout structure of a production SMT patch workshop includes a workbench 1, side panels 2 are symmetrically arranged on both sides of the upper surface of the workbench 1, and a conveyor belt 3 is arranged on the side where the two side panels 2 are close to each other to realize the transportation of circuit boards. A patch mechanism 4 is spanned across the top of the two side panels 2, and a feed port 401 is evenly opened on the surface of one side of the patch mechanism 4, and the material belt can enter through the feed port 401. An extension cylinder 5 is symmetrically arranged on the surface of one side of the patch mechanism 4, and the extension cylinder 5 is perpendicular to the side surface of the patch mechanism 4. The extension cylinder 5 is on the same side as the feed port 401, and an adjustment beam 13 is slidably installed at the end of the extension cylinder 5 and fixed by bolts. The upper surface of the end of the adjustment beam 13 is provided with a U-shaped groove 1 4, a placing rod 15 is arranged between the two U-shaped grooves 14, and the distance between the material trays is controlled by adjusting the relative sliding of the beam 13 and the extension tube 5. The material trays are evenly arranged on the surface of the placing rod 15, and the material trays can rotate on the surface of the placing rod 15. A fixed box 6 is arranged on the surface of the patch mechanism 4 close to the extension tube 5. The fixed box 6 is placed above the feed port 401. A threaded rod 7 is vertically installed between the fixed box 6 and the extension tube 5 through a bearing. A lifting block 8 is screwed on the surface of the threaded rod 7. A guide rotating rod 9 is installed between the two lifting blocks 8 through a bearing. The guide rotating rod 9 is placed across the outer sides of multiple feed ports 401, and multiple material belts are in contact with the surface of the guide rotating rod 9 to guide and support the material belts.

[0022] like Figure 1-Figure 3As shown, a driven conical tooth 701 is provided on the top of the threaded rod 7, and the driven conical tooth 701 is placed inside the fixed box 6. A power shaft 10 is horizontally installed inside the fixed box 6 through a bearing. Two active conical teeth 11 are provided on the surface of the power shaft 10. The active conical teeth 11 are meshed with the driven conical teeth 701. One end of the power shaft 10 passes through the outer surface of the fixed box 6. A knob 12 is provided at the end of the power shaft 10. The knob 12 is placed outside the fixed box 6, which is convenient for controlling the two lifting blocks 8 from the outside, and then controlling the height of the guide rotating rod 9 to adapt to different feeding heights.

[0023] like Figure 4 and Figure 5 As shown, a boss 16 is provided at one end of the upper surface of the adjustment beam 13, and the boss 16 is placed on one side of the U-shaped groove 14. A shift rod 17 is installed on the upper surface of the boss 16 through a pin shaft. The shift rod 17 spans the U-shaped groove 14, and the top of the object rod 15 is limited by the shift rod 17 to prevent it from detaching and improve the stability during patching. A gear 18 is provided at the bottom of the mounting pin shaft of the shift rod 17, and the gear 18 is placed inside the boss 16. A mounting hole 19 is opened on the surface of one side of the boss 16, and a pressing head 20 is slidably installed inside the mounting hole 19. The pressing head 20 protrudes from the surface of one side of the boss 16 so that the pressing head 20 can be pressed from the outside to control the rotation of the shift rod 17.

[0024] Among them, a gear rod 21 is set at one end of the pressing head 20, and the gear rod 21 passes through the inner wall of the mounting hole 19. The gear rod 21 is meshed with the gear 18. Pushing the pressing head 20 can make the gear 18 rotate. Since the gear rod 17 is rotated 90 degrees to one side to facilitate the installation of the storage rod 15, a spring 22 is sleeved on the surface of the gear rod 21. The spring 22 is placed inside the mounting hole 19, and one end of the spring 22 is in contact with the surface of the pressing head 20. The elastic force of the spring 22 is used to make the gear rod 17 span above the U-shaped groove 14 when not subject to external force.

[0025] The working principle of the utility model is as follows: the circuit board to be processed is placed on two conveyor belts 3 for easy transportation. When the circuit board is placed inside the patch mechanism 4, it is patch processed. A plurality of raw material trays are placed on the placement rod 15, and the material belt tube passes through the surface of the guide rotating rod 9 and enters the inside of the patch mechanism 4 through the feed port 401. According to the usage, the knob 12 is rotated to simultaneously drive the two active conical teeth 11 to rotate through the power shaft 10, and then the threaded rod 7 is driven to rotate through the cooperation of the active conical teeth 11 and the driven conical teeth 701 to control the lifting block 8. The material belt is guided and supported by the guide rotating rod 9. At the same time, due to the existence of the spring 22, the pressing head 20 is placed at the outermost side of the stroke, and the gear rod 21 and the gear 18 cooperate to drive the gear rod 17 to rotate, so that the gear rod 17 spans the U-shaped groove 14 when it is not subjected to external force. When loading and unloading materials, the pressing head 20 can be pressed to drive the gear rod 21 to slide inward, and drive the gear 18 to rotate, so that the gear rod 17 rotates 90 degrees, so that the top of the U-shaped groove 14 is open, which is convenient for the installation of the storage rod 15. Conversely, after installation, it can be limited by the gear rod 17 to prevent it from falling off.

[0026] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
