[0002] As a high-precision processing equipment, wafer laser cutting equipment is used in the field of wafer segmentation processing in the semiconductor industry. Compared with other laser processing fields with processing powers of more than kilowatts, the power of wafer laser cutting is often only tens of watts. At the same time, in order to achieve the laser cutting effect, the laser beam must go through complex external optical paths and optical components before cutting the wafer, which will generate some unnecessary laser beams. According to the international IEC60825 laser product standard, the laser hazard level is divided into four major levels, and each level contains multiple different hazard levels. The laser hazard level in wafer laser cutting equipment has reached the hazard level of Class 4 lasers. It is dangerous both in the laser beam and under diffuse reflection observation conditions. It will cause acute damage to the skin and eyes, and has potential fire hazards. Therefore, it is necessary to deal with its excess laser beams.

[0030] A chamber 316 is provided inside the fixed column 314, and a block 318 is connected to the inner wall of the chamber 316 through a spring 317. A slot 319 corresponding to the block 318 is provided on the inner wall of the sleeve block 313. The block 318 is driven to rebound under the elasticity of the spring 317 and embedded in the slot 319 to limit the sleeve block 313 from rotating upward, thereby achieving a further locking effect. An inclined surface is provided on the top of the block 318, and the inclined surface is distributed from bottom to top close to the side of the fixed column 314. The inclined surface can speed up the installation efficiency of the sleeve block 313. After the sleeve block 313 is rotated counterclockwise, the bottom of the sleeve block 313 will conflict with the inclined surface on the top of the block 318, and the sleeve block 313 will push the block 318 to automatically move into the chamber 316. When the block 318 corresponds to the slot 319, the block 318 is driven to embed into the slot 319 under the elasticity of the spring 317, thereby achieving a quick locking effect. A push plate 320 is fixed to the outer wall of the card block 318. The cross section of the push plate 320 is rectangular. The card block 318 is driven in and out of the card slot 319 by pushing the push plate 320, making the operation more comfortable.

[0031] The four corners of the base 411 are all provided with mounting holes 412, and the base 411 can be mounted by screws or bolts corresponding to the mounting holes 412. The top of the base 411 is connected to the bottom of the collector housing 1 through a telescopic frame.

[0032] The telescopic frame includes a rotating cylinder 416, a movable rod 417, a sliding block 418 and a sliding groove 419. The top of the base 411 is rotatably connected to the rotating cylinder 416. One end of the movable rod 417 is fixed to the bottom end of the collector shell 1, and the other end is inserted into the rotating cylinder 416. The sliding block 418 is fixed to the outer wall of the movable rod 417. The inner wall of the rotating cylinder 416 is provided with a sliding groove 419 that slidably cooperates with the sliding block 418. The movable rod 417 can slide up and down under the action of the sliding block 418 and the sliding groove 419, thereby controlling the vertical height of the collector shell 1. A driven gear 425 is fixed to the outer wall of the rotating cylinder 416, a motor 413 is installed on the top of the base 411, the output end of the motor 413 is connected to the rotating rod 414, and a driving gear 415 meshing with the driven gear 425 is fixed to the top of the rotating rod 414. When the motor 413 is turned on to drive the rotating rod 414 and the driving gear 415 to rotate, the driving gear 415 drives the driven gear 425, the rotating cylinder 416, the movable rod 417 and the collector shell 1 to rotate horizontally to achieve the use effect.

[0033] A screw rod 420 threadedly connected to the movable rod 417 is rotatably connected to the inner wall of the bottom end of the rotating cylinder 416, and a gear ring 421 is fixed to the outer wall of the screw rod 420. A hole 424 is opened inside the rotating cylinder 416, and a rack plate 422 meshing with the gear ring 421 is embedded in the hole 424. A movable plate 423 is fixed to the front end of the rack plate 422. Pushing the movable plate 423 back and forth drives the rack plate 422 to move back and forth in the hole 424. The rack plate 422 will drive the gear ring 421 to rotate horizontally and rotate the screw rod 420. Under the action of the thread, the movable rod 417 and the collector shell 1 are driven to move vertically back and forth to achieve a height adjustment effect.

[0034] Working principle: When it is needed, the push plate 320 is moved horizontally to drive the block 318 to be embedded in the chamber 316, so that the spring 317 is compressed, and then the sleeve block 313 is rotated upward to rotate the shielding plate 312 and the rotating plate 311. At this time, the groove 315 can be passed by the fixed column 314, and the shielding plate 312 is driven to rotate 270° clockwise at the axis of the rotating plate 311, as shown in FIG. Figure 2 In the state shown, the concave lens 2 is not blocked, and the use effect is achieved.

[0035] When the direction of the collector shell 1 needs to be adjusted, the motor 413 is turned on to drive the rotating rod 414 and the driving gear 415 to rotate. The driving gear 415 engages with the driven gear 425 to drive the rotating cylinder 416, the movable rod 417, the sliding block 418 and the collector shell 1 to rotate, thereby achieving the effect of controlling the horizontal rotation of the collector shell 1. The rack plate 422 is moved backward by pushing the movable plate 423 backward, and the rack plate 422 drives the gear ring 421 and the screw 420 to rotate, and the movable rod 417 and the collector shell 1 are driven to move upward under the action of the thread, thereby achieving a height adjustment effect, further improving the efficiency of laser beam collection.
