[0002] The electronic muscle stimulator is connected to the electrode sheet through the electrode buckle at the bottom, so that the electric pulse can act on the affected part of the human body. The electrode buckle is an important component, which plays the role of transmitting electric pulses and fixing the electronic muscle stimulator.

[0003] The following problems exist at present: 1. The quality of the electrode buckle is uneven, the center accuracy is not high, it is not easy to select and it is time-consuming, which will cause the following consequences: ① The electrode buckle presses against the casing and is difficult to assemble; ② The electrode buckle and the casing squeeze each other to produce large stress, and the electrode buckle pad has the risk of falling off; ③ The electrode buckle is eccentric relative to the casing hole, the product appearance is poor, and it affects the company and brand image; ④ Rework and replacement are troublesome and time-consuming, which reduces production efficiency. The above phenomena always exist during the turnover and assembly process; 2. Due to the above reasons, there will be products returned from the market for repair. During the rework welding, the electrode buckle also needs to be accurately positioned to avoid the electrode buckle and the casing squeezing each other to produce large stress, causing the electrode buckle pad to fall off; 3. At present, the PCB welding electrode buckle adopts manual welding, the production efficiency is not high, and the quality is greatly affected by the operating level of the operator. It can be obviously found that the precise positioning of the electrode buckle welding is particularly important. Therefore, an electrode buckle welding positioning device is proposed to solve the problem of lack of precise electrode buckle welding in the prior art. Utility Model Content

[0008] Furthermore, the first through hole is a rectangular through hole, which reduces the use of positioning plate materials and thus reduces costs, and provides a larger operating space for the electric soldering iron during soldering, and also facilitates the staff to observe the welding situation.

[0009] Furthermore, each positioning block is step-shaped, which is used to accurately locate the relative position relationship between the electrode buckle and the positioning plate. The area surrounded by each positioning block is the positioning area. The positioning blocks are evenly distributed around the positioning area to position the electrode buckle. At the same time, the contact area between the positioning plate and the electrode buckle is greatly reduced, avoiding excessive heat dissipation during soldering.
