Technical Field

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

[0002] Circuit boards, also known as printed circuit boards, are conductive plates used to connect and support electronic components. They are an indispensable component of modern electronic devices. Before they can be put into use, they undergo several production processes. One of the most basic processes is the use of a cutting device to cut a large circuit board into several smaller ones suitable for use.

However, this utility model still has defects that can be improved:

[0004] In this utility model, bolts are used to drive the pressure plate down, so that the circuit board can be fixed. However, it should be noted that the photolithography and etching steps have been completed before the circuit board is cut, that is, some important circuits are saved on the circuit board. In order to fix the circuit board stably, a certain amount of pressure needs to be applied to the pressure plate. At the same time, the pressure plate is fixedly connected to the bolts. When the pressure plate rotates, it is bound to cause a certain amount of wear on the circuit board. In summary, the clamp will cause unnecessary damage to the circuit board, resulting in economic losses. Improvements are needed to address this problem.

[0029] The present invention will be described in further detail below with reference to the accompanying drawings.

[0030] The working principle of this utility model is as follows Figure 1-Figure 3 As shown, a cutting device includes: a base 1, firstly, a connecting seat 8 is provided in the middle of the upper part of the base 1, and then a support column 7 is fixedly connected to the rear part of the bottom end of the connecting seat 8, and the bottom end of the support column 7 is fixedly connected to the middle part of the rear side of the top end of the base 1. At the same time, in order to make the connecting seat 8 more stable, a reinforcing column 9 is fixedly connected to the rear part of the bottom end of the connecting seat 8, and the bottom end of the reinforcing column 9 is fixedly connected to the rear end of the support column 7;

[0031] A cutting structure 10 is then provided at the front of the bottom end of the connecting seat 8, and a laser cutting machine body is provided at the rear end of the base 1 to cooperate with the cutting structure 10;

[0032] Here, the cutting structure 10 is mainly composed of an electric slide rail 1001, a receiving block 1002, and a laser cutting head 1003. First, a laser cutting head 1003 is arranged at the front part below the connecting seat 8, wherein the laser cutting head 1003 is electrically connected to the laser cutting machine body at the rear, and energy is transmitted from the laser cutting machine body to the laser cutting head 1003. Then, a receiving block 1002 is fixedly connected to the top of the laser cutting head 1003, and the top of the receiving block 1002 is fixedly connected to the electric slide rail 1001, and the guide rail seat of the electric slide rail 1001 is fixedly connected to the bottom end of the connecting seat 8. The effect achieved so far is that the electric slide rail 1001 can automatically drive the receiving block 1002 and the laser cutting head 1003 connected to the receiving block 1002 to move to the specified position;

[0033] Next, a baffle 5 is fixedly connected to the middle of the top of the base 1, and connecting platforms 4 are provided on both sides of the baffle 5. The bottom ends of the connecting platforms 4 on both sides are slidably connected to the top of the base 1. At the same time, fixing devices 6 are provided on the tops of the connecting platforms 4 on both sides. Through the fixing devices 6, the circuit board can be stably fixed;

[0034] Then, hydraulic telescopic columns 3 are fixedly connected to the front and rear parts of the separated sides of the connecting platforms 4 on both sides. It should be noted that the four hydraulic telescopic columns 3 all have a self-locking function. Then, fixed seats 2 are fixedly connected to the separated sides of the hydraulic telescopic columns 3 on both sides, and the bottom ends of the fixed seats 2 on both sides are fixedly connected to the top of the base 1.

[0035] During specific use, the connecting platforms 4 on both sides are first moved to the specified position through the hydraulic telescopic columns 3, and then the circuit board is fixed by the fixing devices 6 on both sides. Then the laser cutting machine body supplies power to the laser cutting head 1003, so that the laser cutting head 1003 can cut the circuit board. During the cutting process, the electric slide rail 1001 can indirectly drive the laser cutting head 1003 to move to the specified position through the receiving block 1002. At the same time, the hydraulic telescopic column 3 on one side pushes the connecting platform 4 to move in one direction, and the hydraulic telescopic column 3 on the other side retracts the corresponding connecting platform 4, so that the fixing device 6 can drive the circuit board to move in the horizontal direction. At this point, the device can cut the circuit board at any point in the horizontal plane.

[0036] The above-mentioned structures together constitute the general appearance structure of a cutting device of the present invention.

[0037] according to Figure 4As shown, in order to further explain the specific working principle of a cutting device of the present invention, the fixing device 6 includes a protective plate 606 fixedly connected to the top of the connecting platform 4 away from the side of the fixing seat 2, and then a pressing plate 604 is provided above the protective plate 606, wherein the bottom end of the pressing plate 604 is fixedly connected to two suction cups 605, where the two suction cups 605 are symmetrically arranged front to back, and at the same time, an air guide tube 607 is connected through each suction cup 605. It should be noted that the connection between the air guide tube 607 and the suction cup 605 is sealed to prevent gas leakage. At the same time, the air guide tube 607 is located on the side of the suction cup 605 away from the pressing plate 604, and the end of the air guide tube 607 away from the suction cup 605 is connected to an external air pump. The gas content in the suction cup 605 can be controlled by the suction and discharge of the air pump.

[0038] At the same time, in order to better fix the air guide tube 607, fixing frames 608 are fixedly connected to the outer walls of the front and rear air guide tubes 607, and then the fixing frames 608 are fixedly connected to the clamping plate 604. It should also be noted that the air guide tube 607 is made of elastic material and has a certain elasticity, so it will not be affected by squeezing and stretching. In other words, the suction cup 605 will not cause damage to the air guide tube 607 during the deformation process.

[0039] Next, in order to control the lifting and lowering of the clamping plate 604, a hydraulic telescopic rod 603 is fixedly connected to the front and rear parts of the top of the clamping plate 604, wherein the hydraulic telescopic rod 603 has a self-locking function, and a receiving plate 602 is fixedly connected to the top of the hydraulic telescopic rod 603, and then the receiving plate 602 is fixedly connected to the side close to the fixed seat 2 with a connecting plate 601, and the bottom end of the connecting plate 601 is fixedly connected to the side of the top of the connecting platform 4 away from the protective plate 606.

[0040] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the circuit board needs to be fixed, the circuit board is first placed on the top of the protective plate 606, and then the hydraulic telescopic rods 603 on the front and rear sides push the clamping plate 604 to move downward, and at the same time, the clamping plate 604 drives the two suction cups 605 to descend. When the suction cup 605 contacts the circuit board, the clamping plate 604 continues to drive the suction cup 605 to descend. During the continuous descent, the external air pump starts to run and extracts the gas in the suction cup 605. In this way, the air pressure in the suction cup 605 is much lower than the external atmospheric pressure. According to the principle of air pressure difference, the circuit board can be stably fixed on the suction cup 605 and will not be displaced during the cutting process.

[0041] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.

[0042] In addition, the electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The hydraulic telescopic rod and hydraulic telescopic column mentioned in the article are both connected to the external oil circuit.
