In terms of use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a cutting component 2 is added to the application document, and the electrical equipment involved in this product is powered by an external power supply.

[0025] More specifically:

[0026] like Figure 1-Figure 4 As shown:

The base 1 is slidably connected through this through hole, and a symmetrically arranged rectangular groove is provided on the upper surface of the base 1. A connecting rod 206 is arranged in the rectangular groove. The connecting rod 206 is fixedly connected to the base 1. A slider 207 is slidably connected to the surface of the connecting rod 206. The slider 207 is fixedly connected to the shell cover 208. A handle 205 is fixed to the upper surface of the movable seat 202. A sliding hole matched with the connecting rod 206 is provided on the surface of the slider 207. The slider 207 and the connecting rod 206 are slidably connected through this sliding hole.

[0028] In this embodiment: when the PCB circuit board cutting device is used, the PCB circuit board to be cut is placed in the shell cover 208, and then the threaded rod 209 is rotated to drive the extrusion plate 211 to move downward to fix the PCB circuit board to be cut. During the movement of the extrusion plate 211, the setting of the telescopic rod 1 210 can limit the extrusion plate 211, so that the extrusion plate 211 is more stable during the movement. Then the shell cover 208 is slid, and the slider 207 is driven to slide on the connecting rod 206. Through the movement of the shell cover 208, the PCB circuit board is driven to move synchronously until the PCB circuit board is in contact with the surface of the cutting knife 204. At this time, the distance from the laser rangefinder 217 to the baffle 219 is a set fixed value. Then the adjusting bolt 218 is rotated to drive the baffle 219 to move. During this process, the distance value between the laser rangefinder 217 and the baffle 219 changes continuously until the distance value between the baffle 219 and the laser rangefinder 217 is directly different from the set fixed value by the distance of the cut PCB circuit board. , then move the shell cover 208, thereby driving the PCB circuit board to move, and at the same time drive the laser rangefinder 217 to move, until the distance between the laser rangefinder 217 and the baffle 219 is again the set fixed value, at this time the position of the PCB circuit board is the cutting position, then press the control switch 215, and energize the electromagnet plate 214 and the electromagnet plate 1 213, the generated magnetic phase adsorption, and the shell cover 208 is locked in position, then push the movable seat 202 to move by the handle 205, and drive the driving motor 203 and the cutting knife 204 to move synchronously by the movable seat 202, in this process, and start the driving motor 203 to rotate the cutting knife 204, and cut the PCB circuit board by the movement and rotation of the cutting knife 204, through the above operation, the cutting and removal size of the PCB circuit board can be adjusted quickly and accurately, providing convenience for the staff, and avoiding the tilting of the PCB circuit board during the cutting process, resulting in uneven cutting of the PCB circuit board, improving the use effect of the device, and meeting the actual use needs.

[0029] It should be noted that when the laser rangefinder 217 is working, it emits a very thin laser beam toward the baffle 219, and then the laser beam reflected back by the target is received by the photoelectric element. Then, the timer measures the time from the emission to the reception of the laser beam. By multiplying this time by the speed of light and then dividing it by two, the distance from the observer to the target can be calculated, and the measured distance is displayed on a display screen (not shown in the figure).

[0030] Going further;

[0031] In an optional embodiment, a protective pad 212 is fixed to the lower surface of the extrusion plate 211 .

[0032] In this embodiment, when the protection pad 212 on the extrusion plate 211 contacts the PCB, the protection pad 212 protects the PCB, thereby preventing the threaded rod 209 from causing extrusion damage to the PCB, thereby improving the use effect of the device.

[0033] Going further;

[0034] In an optional embodiment, a strip plate 220 is provided inside the shell cover 208, symmetrically arranged springs 221 are fixed between the strip plate 220 and the shell cover 208, a telescopic rod 222 is fixed on one side between the strip plate 220 and the shell cover 208 close to the spring 221, and the spring 221 is wound around the surface of the telescopic rod 222.

[0035] In this embodiment: when the PCB circuit board is placed inside the shell cover 208, the side edge of the PCB circuit board is fitted with the surface of the strip plate 220, so as to limit the PCB circuit board and make the PCB circuit board in a horizontal state. By setting the telescopic rod 222, the stability of the strip plate 220 can be increased.

[0036] The working principle and use process of the utility model: when the PCB circuit board cutting device is used, the PCB circuit board to be cut is placed in the shell cover 208, and then the threaded rod 209 is rotated to drive the extrusion plate 211 to move downward. During the movement of the extrusion plate 211, the setting of the telescopic rod 210 can limit the extrusion plate 211, so that the extrusion plate 211 is more stable during the movement. When the protective pad 212 on the extrusion plate 211 contacts the PCB circuit board, the protective pad 212 is used to protect the PCB circuit board, so as to avoid the threaded rod 209 from causing extrusion damage to the PCB circuit board, thereby improving the use effect of the device. When the circuit board is placed inside the shell cover 208, the side of the PCB circuit board is fitted with the surface of the strip plate 220, so as to limit the PCB circuit board and make the PCB circuit board in a horizontal state. The stability of the strip plate 220 can be increased by setting the second telescopic rod 222. Then, the shell cover 208 is slid, and the slider 207 is driven to slide on the second connecting rod 206. Through the movement of the shell cover 208, the PCB circuit board is driven to move synchronously until the PCB circuit board is fitted with the surface of the cutting knife 204. At this time, the distance from the laser rangefinder 217 ray to the baffle 219 is a set fixed value. Then, the adjusting bolt 218 is turned. Then the baffle 219 is driven to move. During this process, the distance value between the laser rangefinder 217 and the baffle 219 is constantly changing until the difference between the distance value between the baffle 219 and the laser rangefinder 217 and the set fixed value is the cut PCB circuit board distance. Then the housing cover 208 is moved, thereby driving the PCB circuit board to move, and at the same time driving the laser rangefinder 217 to move, until the distance between the laser rangefinder 217 and the baffle 219 is the set fixed value again. At this time, the position of the PCB circuit board is the cutting position. Then the control switch 215 is pressed, and the electromagnet plate 214 and the electromagnet plate 1 213 are energized. The magnetic phase generated Adsorb and lock the shell cover 208 in position, then push the movable base 202 to move through the handle 205, and drive the driving motor 203 and the cutting knife 204 to move synchronously through the movable base 202. During this process, start the driving motor 203 to rotate the cutting knife 204, and cut the PCB circuit board through the movement and rotation of the cutting knife 204. Through the above operation, the size of the PCB circuit board to be cut can be adjusted quickly and accurately, which provides convenience for the staff and avoids the uneven cut of the PCB circuit board caused by tilting during the cutting process of the PCB circuit board, thereby improving the use effect of the device and meeting the actual use needs.
