Description

Technical Field

[0001] The utility model relates to the technical field of drive board processing, in particular to a tooling structure for assisting in the processing of drive boards. Background Technique

[0002] During the production of the drive board of a printer, when soldering a triode on a PCBA board that has already passed through the SMT production line, due to manual soldering, the triode is prone to deviation during the soldering process. Due to the cumulative error during the soldering of the triode, when the drive board is connected to other boards through a connector, additional stress is applied, resulting in a possible "twisting" phenomenon of the connector, which may cause the connector pins to break away from the solder pads, and in severe cases, it affects the normal operation of the printer device. For this reason, a tooling structure for assisting in the processing of drive boards is proposed, which can limit the position during the soldering of the triode, and at the same time facilitate the installation of the drive board on the radiator. During repair, the drive board module can be replaced as a whole without considering the problem of mismatch in the installation of the screw holes with the radiator.

[0003] After retrieval, a patent with the Chinese patent application number 201320626584.4 discloses a welding tooling for separating the lamp driver of an LED display module, including a drive board welding tooling. The drive board welding tooling includes a body, and two insertion rods are provided at both ends of the body. The ends of the two insertion rods are necked inward to form an inclined angle. A limit stop block is provided on the body. The two insertion rods are inserted into the drive board through the empty positions of the LED lamp groups on the lamp board through the inclined angle to limit the height between the drive board and the lamp board, and the limit stop block just abuts against the edge of the lamp board for limiting. The following deficiencies exist in the welding tooling in the above patent: When welding electronic components with this tooling, because it is in an inclined state, it requires the staff to continuously hold the electronic components to complete the welding.
