Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board processing devices, and more specifically, to a special jig for trimming PCBA pins. Background Art

[0002] The main purpose of PCBA pin trimming is to ensure the appearance and welding requirements of the product. Pin trimming is beneficial to the welding of components for small devices. Especially in automatic welding, it can prevent components from falling off and cold soldering, reduce solder joint trimming, and improve the heat dissipation of components.

[0003] Usually, the pins of the PCBA board may be skewed during transportation or movement. Some pins may also cause the length of the lower PCBA board to be different due to the welding process, affecting the smoothness of subsequent assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a special jig for PCBA pin trimming to solve the problems raised in the above background technology.

[0005] A special jig for trimming PCBA pins includes a device outer shell, a pair of mounting seats fixedly installed on the front and rear sides of the inner cavity of the device outer shell, a driven rod rotatably installed on the front side of the two mounting seats, a driving rod rotatably installed on the rear side of the two mounting seats, a driving mounting plate fixedly installed on one side of the mounting seat, a driving motor fixedly installed on the lower side of the driving mounting plate, a pair of sliding plates fixedly installed on the upper side of the two mounting seats, an isolation plate fixedly installed between the two mounting seats, a pair of transmission belts provided between the driving rod and the driven rod, a connecting member fixedly installed on the upper side of the transmission belt, and a mounting guide column fixedly installed on the upper side of the connecting member;

[0006] A pair of trimming grooves are fixedly installed on the upper side of the isolation plate, and an electric cutting member is fixedly installed on the side of the trimming groove. A trimming blade is provided at the output end of the electric cutting member located on one side of the trimming groove.

[0007] Furthermore, a second transmission member is fixedly installed on the output end of the driving motor, a first transmission member is fixedly installed on the same end of the driving rod as the driving motor, and a driving belt is provided between the first transmission member and the second transmission member.

[0008] By adopting the above technical solution, the second transmission member drives the first transmission member to rotate through the driving belt, thereby controlling the rotation of the driving rod.

[0009] Furthermore, a pair of sliding grooves are provided on the side of the sliding plate, and sliding members are fixedly installed on both ends of the mounting guide column.

[0010] By adopting the above technical solution, the sliding members on both sides of the installation guide column are arranged in the sliding groove, and the sliding groove allows the installation guide column to slide horizontally within the range and maintain stability.

[0011] Furthermore, a limiting member is provided between the two mounting guide pillars.

[0012] By adopting the above technical solution, the limiting member can limit the position between the installation guide pillars.

[0013] Furthermore, a mounting threaded opening is provided in the middle of the mounting guide column.

[0014] By adopting the above technical solution, a clamp corresponding to the PCAB board can be fixedly installed inside the mounting threaded opening by means of bolts to clamp and fix the PCAB board.

[0015] Furthermore, a triangular inclined notch is formed on a side of the trimming groove close to the driving motor.

[0016] By adopting the above technical solution, when the PCAB pin enters between the trimming grooves from the notch position, the inclined pin of the PCAB fixed between the mounting guide pillars can be limited and corrected.

[0017] Furthermore, a waste recovery groove is provided at the lower end of the isolation plate at a vertical position of the trimming groove, and the waste recovery groove and the isolation plate are fixedly connected by bolts.

[0018] By adopting the above technical solution, the waste cut by the trimming blade will fall into the waste recovery tank under the action of gravity.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] In the utility model, a structure equipped with a driving motor is provided to set the PCAB board on the installation guide column. The driving motor drives the driving rod to rotate through the driving belt, so that the installation guide column can be moved as a whole on the upper side of the isolation plate. The pins on the lower side of the PCAB board will be straightened by the trimming groove and cut as a whole by the electric cutting member, so that the pins can be quickly trimmed.
