Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cutting equipment, in particular to a cutting device for circuit board production. Background Art

[0002] Circuit boards are divided into ceramic circuit boards, alumina ceramic circuit boards, circuit boards, aluminum substrates, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards can be called printed circuit boards or printed circuit boards, and have the characteristics of high wiring density, light weight, thin thickness, and good bending properties. Circuit board production cutting devices can be used to cut circuit boards. In the manufacturing process of circuit boards, a whole circuit motherboard needs to be cut to meet specific production needs. Circuit board cutting devices can cut and disconnect circuit boards, and can also perform "V" groove cutting on circuit boards.

[0003] Existing cutting devices for circuit board production usually do not have the ability to cut circuit boards of different sizes, and can only cut designated special circuit boards. The functions are relatively simple and cannot meet the needs of cutting circuit boards of different sizes. Therefore, a cutting device for circuit board production is proposed.

[0004] A cutting device for circuit board production disclosed in the announcement number CN209665467U, although the cutting device for circuit board production relates to the technical field of circuit board cutting equipment, in order to solve the problem that the machine operation is single and the efficiency is affected by manual operation. A cylinder mechanism is arranged above the bottom support plate, and side support plates are arranged on both sides of the bottom support plate. The upper end of the cylinder mechanism is arranged with a cylinder mechanism output end, and an output end fixing plate is arranged above the output end of the cylinder mechanism. A wooden operating table is arranged above the output end fixing plate, and a fixed frame is arranged above the wooden operating table.

[0006] Therefore, it is necessary to invent a cutting device for circuit board production to solve the above problems. Utility Model Content
