Embodiment 1

[0033] Such as figure 1 with figure 2 As shown, a circuit board laser cutting machine includes a processing table 7, and a cutting head assembly 1 is installed above the processing table 7. The cutting head assembly 1 adopts the cutting head assembly used in laser machines in the prior art.

[0034] The processing table 7 is provided with a rectangular fixing groove 22, and four splints 11 are slidably installed around the fixing groove 22, and the four splints 11 are all connected with a power part for driving its sliding, and the power part adopts the cylinder 5 in the present embodiment.

[0035] A box body 15 with an open top is installed below the processing table 7 , and two pistons 10 are vertically installed in the box body 15 , and the two pistons 10 are slidably connected in the box body 15 . A suction cavity 9 is formed between the two pistons 10 , and a plurality of suction holes 6 are opened at the bottom of the fixing groove 22 , and the suction holes 6 communi...

Embodiment 2

[0042] Such as image 3 As shown, a top plate 17 is installed laterally slidingly in the splint 11 , and a spring 18 is connected between the top plate 17 and the splint 11 . A pressing assembly for pressing the circuit board 21 is also installed on the clamping plate 11, and the pressing assembly includes a rotating roller, which is connected with a pressing plate 20, and the pressing plate 20 can be rotated and pressed on the circuit board 21 by the rotating roller. Key is connected with gear 19 on the turning roller, is welded with tooth bar 16 on the top plate 17, and tooth bar 16 is meshed with gear 19.

[0043] In the initial state, the right end of the top plate 17 extends out of the splint 11. When the splint 11 moves to abut against the circuit board 21, the top plate 17 can be retracted to the inside of the splint 11 under the action of abutting against the circuit board 21, and the spring 18 is compressed. When the top plate 17 moves, it can drive the rotating roll...

Embodiment 3

[0045] The difference between this embodiment and Embodiment 1 is that a refrigerant is placed in the suction chamber 9, and in this embodiment, the refrigerant is dry ice, and a refueling port is provided on the side wall of the suction chamber 9 (not shown in the figure). ), the refueling port is hinged with a sealing door for sealing the refueling port.

[0046] Placing refrigerant in the suction cavity 9 can reduce the temperature of the suction cavity 9. When the partition plate 8 is pulled apart to expose the suction hole 6, the cold air in the suction cavity 9 can contact the circuit board 21, thereby Cool down the circuit board 21 to avoid damage caused by excessive temperature of the circuit board 21 during the cutting process.

Abstract

The invention relates to the technical field of cutting, in particular to a circuit board laser cutting machine. The machine comprises a machining table, a cutting head assembly is arranged above themachining table, a fixing groove is formed in the machining table, a plurality of air suction holes are formed in the bottom of the fixing groove, an air suction mechanism is arranged below the machining table and communicated with the air suction holes, and clamping plates are arranged around the fixing groove in a sliding mode. The clamping plates are connected with power pieces used for drivingthe clamping plates to move. A circuit board is fixed by combining two modes of clamping by the clamping plates and negative pressure adsorption, the fixing stability of the circuit board is improved, the clamping plates arranged in a sliding mode are adopted, the machine is suitable for fixing circuit boards of different sizes, and the application range of the machine is expanded. The problems that an existing cutting machine cannot adapt to fixing of different circuit boards, and the fixing effect is poor are solved.

Description

technical field [0001] The invention relates to the technical field of cutting, in particular to a circuit board laser cutting machine. Background technique [0002] As an emerging processing method, laser cutting technology is widely used in the field of metal processing due to its flexible processing, high efficiency and high quality. At present, laser cutting is also widely used in the processing of circuit boards. [0003] The current circuit board laser cutting machine only simply places the circuit board in the positioning groove of the processing table when cutting the circuit board. For the fixing of the board, different processing tables are equipped for different sizes of circuit boards, which undoubtedly increases the cost, and the fixing stability of the circuit board is not enough simply by placing the circuit board in the positioning groove. Contents of the invention [0004] The present invention intends to provide a circuit board laser cutting machine to ...
