[0001] The invention relates to the field of flexible circuit board connector welding, and in particular to a flexible circuit board connector welding device. Background Art

[0002] With the popularization and utilization of flexible circuit boards, the installation of flexible circuit boards and the installation of components on flexible circuit boards are also very important in production. When installing a flexible circuit board on a rigid circuit board, it is usually necessary to install a corresponding connector on the flexible circuit board for corresponding connection with the connectors provided on other circuit boards.

[0003] The existing installation of connectors on flexible circuit boards is performed by manual welding with a handheld welding gun. Some large factories also use automatic welding machines for welding. However, during welding, a connector needs to be placed on a flexible circuit board by a robot, and then the pair of connectors and the flexible circuit board are welded together by another robot, and the operation speed is slow.

[0004] Therefore, it is necessary to provide a new flexible circuit board connector welding device to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a flexible circuit board connector welding device.

When the device is in use, the flexible circuit board is placed on the vacuum adsorption workbench, and the material roll can be released under the action of the reeling device. At the same time, the fixed frame is moved to the top of the material roll through the manipulator and the controller, and the connector is adsorbed by the vacuum suction cup. The fixed frame is then moved to the flexible circuit board. Through the operation of the equidistant adjustment mechanism, several connectors adsorbed by the vacuum suction cup can be placed on the corresponding flexible circuit board. The single pin on the connector is loaded through the tinning mechanism, and the flexible circuit board and the connector are welded by the welding gun. The synchronous moving structure and the equidistant adjustment mechanism cooperate with each other to weld all the pins.

[0007] Preferably, the equidistant adjustment mechanism includes a limit rod, a limit hole, a fixed plate, a synchronous spring and a cylinder. The limit rod is symmetrically fixed inside the fixed frame. The two limit rods are slidably connected with the moving block. The limit hole is provided on the moving block at the position corresponding to the limit rod. The limit hole is slidably connected with the limit rod.

A cylinder is fixedly installed at one end of the fixed frame. The moving end of the cylinder passes through the fixed frame and is fixedly connected to one side of the nearest moving block. The moving end of the cylinder is slidably connected to the fixed frame. The moving block close to the cylinder is driven by the cylinder to slide along the limit rod. Since there is a synchronous spring connecting two adjacent fixed plates, the pulling of the synchronous spring will drive several moving blocks to move synchronously. At this time, the forces on several synchronous springs are the same, and the distances between several moving blocks will be controlled to be the same, which is used to place the connector on the corresponding flexible circuit board.

[0008] Preferably, a positioning hole is opened in the middle of the fixing plate, a positioning rod is fixedly installed in the fixing frame at a position corresponding to the positioning hole, the positioning rod is slidably connected to the positioning hole, and the synchronous spring is sleeved on the outer side of the positioning rod. During the movement of the moving block, the synchronous spring can be controlled by the positioning rod to prevent the synchronous spring from twisting.

[0009] Preferably, the synchronization spring is arranged close to the outer side of the positioning rod, so as to further prevent the synchronization spring from being twisted during long-term use.

The motor drives the gear to rotate, and the meshing of the gear and the rack will drive the moving block here to move, and move the semicircular block to the inside of the next semicircular groove. During this process, the lifting plate will rise and then fall along the fixed rod, and move the tinning mechanism and the welding gun to the next pin on the connector. At the same time, the cylinder drives the moving block close to the cylinder to move, ensuring that the distance between several moving blocks will not change. This reciprocating process can be used to weld all the pins on one side.

[0011] Preferably, a pulling spring is sleeved on the outer side of the fixed rod, one end of the pulling spring is fixedly connected to the lower surface of the lifting plate, and the other end of the pulling spring is fixedly connected to the moving block.
