Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, an automatic PCB cutting machine is provided with a cutting device, including a base frame 1, a cutting mechanism 2 and a cutting rotation mechanism 3. Both the cutting mechanism 2 and the cutting rotation mechanism 3 are connected to the base frame 1, and the cutting rotation mechanism 3 is located on one side of the cutting mechanism 2.

[0030] The tape cutting mechanism 2 includes a tape cutting and conveying assembly 21 and a tape cutting and slitting assembly 22. The tape cutting and slitting assembly 22 is located on one side of the tape cutting and conveying assembly 21 and connected to the base frame 1. The tape cutting and slitting assembly 22 includes a tape cutting base 221 and a laser emitter 222. The tape cutting base 221 is located on one side of the tape cutting and conveying assembly 21 and fixedly connected to the base frame 1. The laser emitter 222 is fixedly connected to the tape cutting base 221. The laser emitter 222 emits a high-energy laser beam that acts on the tape on the PCB board, using the high energy of the laser to cut the tape. Because the laser emitter 222 is fixed on the tape cutting base 221, and the tape cutting base 221 is fixedly connected to the base frame 1, the stability of the laser emitter 222's position is ensured, thereby ensuring the accuracy and consistency of tape cutting.

[0031] The rubber tapping rotation mechanism 3 includes a rotation drive assembly 31 and a rubber tapping rotary disk 32. The rotation drive assembly 31 is connected to the base frame 1, and the rubber tapping rotary disk 32 is connected to the rotation drive assembly 31 and is disposed on one side of the rubber tapping conveying assembly 21.

[0032] The automatic PCB tape cutting machine provided in this application has a tape cutting device that automatically rotates the PCB by 90° through the tape cutting rotation mechanism 3 and automatically cooperates with the tape cutting component 22 to complete the tape cutting of the four sides of the PCB board, thereby improving the tape cutting efficiency of the PCB board.

[0033] In another embodiment of this utility model, the rubber tapping conveyor assembly 21 includes a rubber tapping conveyor frame 211, a rubber tapping conveyor motor 212, a rubber tapping conveyor pulley 213, and a rubber tapping conveyor belt 214. The rubber tapping conveyor frame 211 is fixedly connected to the base frame 1, the rubber tapping conveyor motor 212 is fixedly connected to the rubber tapping conveyor frame 211, the rubber tapping conveyor pulley 213 is fixedly connected to the rubber tapping conveyor motor 212, and the rubber tapping conveyor belt 214 is fixedly wound around the rubber tapping conveyor pulley 213.

[0034] The working process of the rubber tapping and conveying assembly 21 is as follows:

[0035] The rubber tapping conveyor motor 212 is powered on and starts, converting electrical energy into mechanical energy and outputting rotational power. Since the rubber tapping conveyor pulley 213 is fixedly connected to the output shaft of the rubber tapping conveyor motor 212, the motor's rotation directly drives the rubber tapping conveyor pulley 213 to rotate synchronously. As a key component for power transmission, the rubber tapping conveyor pulley 213 transmits the motor's rotational motion to the rubber tapping conveyor belt 214. The rubber tapping conveyor belt 214 is fixedly wound around the rubber tapping conveyor pulley 213. When the rubber tapping conveyor pulley 213 rotates, it drives the rubber tapping conveyor belt 214 to circulate through friction. The PCB board placed on the rubber tapping conveyor belt 214 is transported forward by the friction of the belt surface. During the transport process, the rubber tapping conveyor belt 214 provides stable support and transport power for the PCB board, ensuring that the PCB board can smoothly and accurately reach the designated position below the rubber tapping and cutting assembly 22 for rubber tapping operations.

[0036] In another embodiment of this utility model, two adhesive cutting components 22 are provided and arranged in parallel and opposite directions. Both adhesive cutting components 22 are fixedly connected to the base frame 1. The laser emitters 222 of the two adhesive cutting components 22 simultaneously emit high-energy laser beams. The laser beams are focused on the adhesive tape on the PCB board, and the high heat of the laser causes the adhesive tape to melt or vaporize rapidly, thereby achieving cutting. During the cutting process, since the two laser emitters 222 act from different directions, even for some irregularly shaped PCB boards or PCB boards with special adhesive tape layouts, it can be ensured that the adhesive tape is completely cut. For example, for some irregularly shaped PCB boards, lasers from different angles can effectively cut the adhesive tape at the edges and corners, reducing cutting dead angles.

[0037] In another embodiment of this utility model, the rotary drive assembly 31 includes a rubber-tapping rotary fixing frame 311, a rubber-tapping rotary motor 312, and a rubber-tapping rotary shaft 313. The rubber-tapping rotary fixing frame 311 is fixedly connected to the base frame 1, the rubber-tapping rotary motor 312 is fixedly connected to the rubber-tapping rotary fixing frame 311, one end of the rubber-tapping rotary shaft 313 is fixedly connected to the rubber-tapping rotary motor 312, and the other end is fixedly connected to the rubber-tapping rotary disk 32, which is disposed on one side of the rubber-tapping conveyor belt 214. By rotating the rubber-tapping rotary motor 312, the rubber-tapping rotary shaft 313 and the rubber-tapping rotary disk 32 are driven to rotate, thereby rotating the PCB board placed on the rubber-tapping rotary disk 32, so as to cut the tape at different positions on the PCB board.

[0038] After the first tape cutting of the PCB board is completed, the PCB board is transported to the tape cutting rotary table 32. The tape cutting rotary motor 312 is started, and the rotation of the tape cutting rotary shaft 313 and the tape cutting rotary table 32 drives them to rotate, thereby rotating the PCB board placed on the tape cutting rotary table 32 by a certain angle. After rotation, the PCB board is transported again to the tape cutting assembly 22, and the laser emitter 222 is started to perform a second cut on the uncut portion of the tape on the PCB board.

[0039] In another embodiment of this invention, each cutting base 221 is provided with two laser emitters 222, both of which are fixedly connected to the cutting base 221. Since the two laser emitters 222 are fixed to the same cutting base 221, their relative positions remain stable. They emit high-energy laser beams, which are directed at the tape on the PCB board from different angles. For example, one laser emitter 222 may emit a laser perpendicular to the PCB board surface to cut horizontally oriented tape; the other laser emitter 222 emits a laser at a certain angle, effectively cutting tape at the edges of the PCB board or in areas with a certain slope. This multi-angle cutting method can cover a wider area of ​​tape.

[0040] The automatic PCB tape cutting machine provided in this application has a tape cutting device that automatically rotates the PCB by 90° through the tape cutting rotation mechanism 3 and automatically cooperates with the tape cutting component 22 to complete the tape cutting of the four sides of the PCB board, thereby improving the tape cutting efficiency of the PCB board.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
