Description

Technical Field

[0001] The utility model relates to the technical field of spot plating machines, in particular to a belt tension adjustment mechanism of a spot plating machine. Background Art

[0002] For some products with special performance requirements, special coatings are required at specific locations to achieve corresponding functions. For example, some tiny component connection points on mobile phone circuit boards and computer motherboards often only require electroplating operations at specific local locations.

[0003] Spot plating machines can precisely apply plating solution to these tiny target areas, achieving a precise metal coating and avoiding affecting other areas that do not require spot plating. For example, when gold plating a pin on a circuit board, a spot plating machine can accurately complete the gold plating only at the soldering point of that pin, ensuring good conductivity and soldering performance without coating the entire circuit board with gold. This not only saves precious metal materials but also meets the requirements of refined production.

[0004] During the operation of the spot plating machine, different working stages require different operating speeds to accurately complete the spot plating operation. If the belt tension cannot be adjusted, the belt will slip due to being too loose. In this way, it will not be possible to accurately drive the corresponding transmission components according to the set transmission ratio, making the operating speed of the spot plating machine unstable, thereby affecting the position accuracy of the spot plating, resulting in deviations in the plating points and affecting product quality. Therefore, a belt tension adjustment mechanism for a spot plating machine is proposed to solve the above problems. Utility Model Content

The motor 8 is designed here to drive the belt to rotate. The driving end of the motor 8 is fixedly connected to a rotating column 9. The rotating column 9 is designed here to wrap the belt. The inside of the body 1 is slidingly connected to the outside of the rotating column 9. A sliding groove 10 is opened inside the body 1. The sliding groove 10 is designed here to provide support for the sliding of the rotating column 9. The inside of the sliding groove 10 is slidingly connected to the outside of the rotating column 9. The inside of the body 1 is fixedly connected to a workpiece auxiliary clamping assembly

[0035] Reference Figures 3 to 5 The auxiliary clamping assembly includes a plurality of rollers 11, which are designed here to support the sliding of the working parts. The outside of the plurality of rollers 11 is fixedly connected to the inside of the body 1, and the inside of the body 1 is fixedly connected to a motor 2 12. The motor 2 12 is designed here as a driving source for the clamping action. The driving end of the motor 2 12 is fixedly connected to a circular gear 13. The circular gear 13 is designed here as a power transmission.

[0037] Working principle: When it is necessary to adjust the belt tension, start the cylinder 2 and push the cylinder 2. The cylinder 2 transmits power to the rotating plate 4, affecting the rotating plate 4 to rotate. The rotating plate 4 slides in the transmission groove 19, and then drives the movable arm 7 to rotate under the support connection of the two rotating blocks 6 and the support block 5. The movable arm 7 is controlled to move toward the side of the winding column 18, thereby driving the rotating column 9 to move under the support of the sliding groove 10 in the body 1, so that the position of the rotating column 9 changes, and the belt wrapped around the outside of the rotating column 9 is adjusted. This position change directly acts on the belt wrapped around the outside of the rotating column 9, causing the tightness of the belt to change, and finally achieving precise adjustment of the belt tension, ensuring that the transmission system of the entire equipment can operate efficiently and stably under appropriate belt tension.

[0038] When it is necessary to clamp and position the workpiece of the spot plating machine to make the work more precise, start the motor 2 12, the driving end drives the circular gear 13 to rotate, and the external drive drives the two meshing gear plates 14 to slide towards each other. Under the support of the support arm 15, the gear plate 14 drives the two clamping plates 16 to move towards each other, clamping and positioning the workpiece located on top of the multiple rollers 11 so that it will not deviate. In this way, the workpiece is always in a firmly fixed state throughout the work process of the spot plating machine, thereby laying a solid foundation for the precise implementation of the spot plating process, ensuring that the position of each spot plating is accurate and correct, and greatly improving the quality and efficiency of the spot plating machine.
