Description

Sheet cutting fixture

technical field

The utility model relates to a device for cutting circuit boards, in particular to a plate cutting tool for cutting parts to be cut of printed circuit boards.

Background technique

During the production process of each printed circuit board in the printed circuit board factory, a certain width of the cutting part is reserved around the board and its center, and at least two or more circuits are printed in the cutting part, so that For the client's quality control inspection, check whether the circuit of the printed circuit board meets the specifications specified by the customer. After the inspection items meet the customer's requirements, the client starts to feed materials and carry out circuit board parts insertion and tinning on the production line. Furnace, testing and final assembly of related components for shipment. Generally, after the printed circuit board passes through the tin furnace, in addition to manual insertion, another task is to remove the part of the printed circuit board to be cut.

Common ways to remove the parts to be cut are as follows. One is to make a deep embedded long slot on the table top of the production line that can fix the parts to be cut, and then place the parts to be cut on the printed circuit board in the embedded slot. Hold the two sides of the printed circuit board with both hands while facing the printed circuit board in the long slot and pull it forward or backward to remove the part of the printed circuit board to be cut. The second is to use a simple hand-held T-shaped folding board jig, firstly fix the printed circuit board in a jig, such as shown in Taiwan patent announcement M288485, and expose the part to be cut of the printed circuit board, and then the production personnel manually Hold the handle of the T-shaped folding board jig, insert the fitting groove of the T-shaped folding board jig in parallel to the part to be cut of the printed circuit board, and remove the part to be cut of the printed circuit board by the force of the wrist. The third is to use a pneumatic cutting machine, such as the product model HS-JAW250 of Hoshuo Technology Co., Ltd., to align the cutting line of the part to be cut of the printed circuit board with the cutter, and use the upper and lower cutters to close the part of the printed circuit board to be cut. Cutting parts are removed.

The above-mentioned existing means for removing the parts to be cut of the circuit board can only process one side of the part to be cut at one time. Since there are multiple parts to be cut on the periphery of the general circuit board, it is necessary to repeatedly change the cutting position of the circuit board. , and then use jigs or knives to process the parts to be cut on one side at a time, which will cost more processes and time costs.

Sometimes the part to be cut of each batch of printed circuit boards is not necessarily a regular rectangle. When the printed circuit boards are irregular in shape, the production line needs to replace different jigs according to different batches of circuit boards to fix the circuit boards. Irregular-shaped circuit boards require more labor and time for the parts to be cut. Once a large amount of processing removes the parts to be cut, it will take more manual processing and time, resulting in an increase in production costs, which is not what manufacturers are willing to see.

In the prior art, regarding the technical means of removing the part to be cut of the printed circuit board, only the part to be cut on one side of the printed circuit board can only be processed once, resulting in complicated cutting procedures. For printed circuit boards, additional cutting and fixing jigs corresponding to different shapes of circuit boards must be designed, which will cause the problem of increased manufacturing costs.
