[0002] The barrel plating process is a common electroplating method in the electroplating industry, mainly used for small parts and workpieces that need to be mass-produced, such as the NdFeB industry. In the barrel plating process, the staff needs to place the parts to be plated into the barrel, and then the barrel is hoisted to the electroplating tank by the lifting equipment. The electroplating tank is equipped with a power for the barrel to roll, and the input gear of the barrel needs to be matched with the rolling power to realize the rotation of the barrel in the electroplating tank, so that the surface of the NdFeB is evenly plated. In production, the NdFeB barrel has always been the key to restricting fully automatic production. The problem of poor conductivity of the barrel and stopping of rotation causing the whole barrel of parts to be scrapped has been difficult to solve, resulting in a loss of tens of thousands of processing fees.

[0011] Beneficial effects:

[0012] (1) In the electroplating line roller rotation detection device described in the utility model, the detection unit is used to detect the rotation state of the detection gear.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] like Figure 1-Figure 2As shown, the electroplating line roller rotation detection device includes a detection gear 2 installed on the electroplating tank 1, a power gear 3 is arranged on one side of the detection gear 2, and the detection gear 2 and the power gear 3 are arranged parallel to each other, the power gear 3 is fixedly installed on the output shaft of the power motor 5, the power motor 5 is fixedly installed on the electroplating tank 1, the roller 6 is detachably arranged in the electroplating tank 1, and a transmission gear 4 is arranged on the transmission shaft of the roller 6. The transmission gear 4 can be meshed with the power gear 3 and the periphery of the detection gear 2. The power gear 3 drives the detection gear 2 to rotate through the transmission gear 4. A detection unit 7 is arranged on the electroplating tank 1, and the detection unit 7 is used to detect the detection gear The rotation state of the wheel 2 is detected by the detection unit 7 in real time to detect the rotation of the gear 2, thereby indirectly detecting whether the transmission gear 4 is in a rotation state. By indirectly sensing the stoppage of the roller 6, the real-time state of the roller 6 at each workstation is monitored, the product failure rate is reduced, and the production cost is reduced. The detection gear 2 is equipped because the roller 6 and the transmission gear 4 need to be hoisted onto the electroplating tank 1 by hoisting equipment. When hoisting and assembling the transmission gear 4, an assembly gap will be generated, which is not conducive to the installation of the detection unit 7. The detection gear 2 and the detection unit 7 are both installed on the electroplating tank 1 and do not need to be moved, thereby reducing the component loss caused by moving hard contact.

[0024] The detection unit 7 is a proximity sensor of the prior art. The execution end of the proximity sensor can detect the presence of sawtooth of the detection gear 2. The proximity sensor and the detection gear 2 adopt non-contact type to prevent component wear and increase the service life of the components. When the detection gear 2 rotates, the presence of sawtooth is intermittently sensed by the proximity sensor, and the proximity sensor signal is transmitted to the controller. The controller determines whether the detection gear 2 and the transmission gear 4 rotate synchronously to determine whether the drum 6 rotates. The control method of this embodiment is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. This article is mainly used to protect mechanical devices. This article does not explain the control method and circuit connection in detail.

[0025] The periphery of the drum 6 is rotatably sleeved on the hanger 8, and the external lifting device can be detachably connected to one end of the hanger 8. The two sides of the hanger 8 can be overlapped to the upper end of the electroplating tank 1. The first synchronous wheel 9 is arranged on the transmission shaft of the drum 6, and the central axis 12 is rotatably sleeved on the hanger 8. The second synchronous wheel 10 is arranged at one end of the central axis 12, and the transmission gear 4 is installed at the other end of the central axis 12. The periphery of the first synchronous wheel 9 forms a synchronous transmission structure with the periphery of the second synchronous wheel 10 through the intermediate gear 11.

[0026] A lap shaft 14 is respectively arranged at both ends of the hanger 8, and each lap shaft 14 can be lapped to the upper end of a V-shaped seat 13, and the lower end of the V-shaped seat 13 is installed to the upper end of the electroplating tank 1. The lap shaft 14 is a fixed structure for the hanger 8 to be installed on the electroplating tank 1, and an adaptor slider 15 is fixedly sleeved on the lap shaft 14. One end of the adaptor slider 15 is a truncated cone structure, and a notch is arranged on one side of the V-shaped seat 13. The outer periphery of the truncated cone structure can slide down from the notch. The adaptor slider 15 and the notch cooperate to form the positioning structure of the hanger 8, the roller 6 and the central axis 12 on the electroplating tank 1. When the lifting equipment hangs the hanging foot on the electroplating tank 1, if there is a misalignment problem of the hanger 8, the adaptor slider 15 first contacts with the V-shaped seat 13, and guides the hanger 8 and the roller 6 to be centrally arranged in the electroplating tank 1 through the guidance of the notch.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
