Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a positioning card welding device. Background Art

[0002] The mining identification card is a card specially designed for locating personnel or equipment in a mining environment. It combines wireless communication technology with positioning technology to achieve precise positioning underground or in closed spaces. It improves the safety of mining operations. The identification card includes a card body, a positioning card, and a high-speed signal cable welded on the positioning card. The positioning card is a PCB board. The high-speed signal cable needs to be welded on both sides of the positioning card to provide a shorter and more direct signal path, reduce delays and attenuation in signal transmission, and improve signal quality.

[0003] A Chinese patent document with announcement number CN116511802B discloses a cable welding device for automatic flip welding, wherein the front side of the circuit board has three welding positions and the back side has one welding position. First, a suitable number of circuit boards are preset in the circuit board conveying mechanism, and a suitable number of cable groups consisting of a plurality of cables are preset in the cable conveying mechanism. During the welding process, each time the circuit board conveying mechanism feeds a circuit board into the circuit board positioning mechanism, when welding the circuit board, the cable positioning mechanism first conveys a group of cable groups to the first welding position on the front side of the circuit board, and the welding mechanism welds the cable group at the first welding position and the front side of the circuit board. After the welding mechanism completes the welding of the first welding position, the cable positioning mechanism transports the next group of cables to the next welding position on the front of the circuit board. The welding mechanism sequentially welds each welding position on the front of the circuit board. After the welding of the front of the circuit board is completed, the cable positioning mechanism transports the first group of cables on the back of the circuit board to the first welding position on the back of the circuit board. The circuit board positioning mechanism flips the circuit board and faces the back of the circuit board to the welding mechanism. After the welding of each welding position on the back of the circuit board is completed in sequence, the welded circuit board is taken out, and the next circuit board is sent from the circuit board conveying mechanism to the circuit board positioning mechanism to perform the welding of the next circuit board. In the above patent, after the welding of one circuit board is completed, the welding of the next circuit board is performed. Each welding of a circuit board requires driving the welding mechanism to move multiple times so that the welding mechanism corresponds to different welding positions. The driving device that drives the welding mechanism to move operates frequently, which increases the repair and maintenance costs. Summary of the invention
