[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 5A cutting structure for MOS packaging production includes a support frame 1. Adsorption components 5 for adsorbing slag generated during cutting are provided at both the upper and lower ends of the support frame 1. The adsorption components 5 include an adsorption air pump 501 fixedly installed on the upper surface of the support frame 1. A collection box 502 is fixedly connected to the input end of the adsorption air pump 501. A filter pad 503 is fixedly installed on the side wall of the connection between the collection box 502 and the adsorption air pump 501. A pull-out plate 504 is slidably installed inside the collection box 502. An air extraction pipe 505 is fixedly connected to the input end of the collection box 502. A manifold 506 is fixedly connected to the end of the air extraction pipe 505. Multiple suction holes 507 are provided on the side wall of the manifold 506. A cutting position control component 3 is provided both inside and outside the support frame 1. The cutting position control component 3 includes a limiting groove 305 opened inside the bottom end of the support frame 1. A sliding seat 304 is slidably installed inside the limiting groove 305. The bottom end of the sliding seat 304... An electric cylinder 306 is fixedly installed, and a mounting base 308 is fixedly installed at the power output end of the electric cylinder 306. A guide rod 307 slides through the interior of the mounting base 308. A cutting assembly 4 is provided on the lower end face of the mounting base 308. The cutting position control assembly 3 also includes a servo motor 301 fixedly installed on the side wall of the support frame 1. A ball screw 302 is fixedly connected through the support frame 1 at the output end of the servo motor 301. A ball nut 303 is sleeved on the outside of the ball screw 302. The ball nut 303 is fixedly connected to the sliding seat 304. The cutting assembly 4 includes a cutting motor 401 fixedly installed on the lower end face of the mounting base 308. A rotating shaft 402 is fixedly installed at the output end of the cutting motor 401. A cutting disc 403 is fixedly installed at the middle position of the rotating shaft 402. A disc cover 404 is sleeved on the outside of the cutting disc 403. The disc cover 404 has a semi-circular structure. The arc surface of the disc cover 404 is embedded with a semi-circular manifold 506.

[0029] By adopting the above technical solution, when the MOS package needs to be cut, the servo motor 301 is activated. The servo motor 301 drives the ball screw 302 to rotate. The ball screw 302 and the ball nut 303 are connected by a conventional ball screw transmission method, which drives the ball nut 303 and the sliding seat 304 to move left and right in the limiting slide groove 305. When it moves to the appropriate position, the electric cylinder 306 is activated. The electric cylinder 306 drives the mounting seat 308 to slide on the guide rod 307, thus adjusting the height of the cutting assembly 4. In the cutting process, the cutting motor 401 is activated, which drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the cutting disc 403 to cut the MOS package to be processed. At the same time as the cutting process, the adsorption air pump 501 is activated. The adsorption air pump 501 creates a negative pressure in the collection box 502, the suction pipe 505, and the manifold 506. This creates a suction force inside the disc cover 404 through the suction port 507. The suction force inside the disc cover 404 accelerates the airflow around the disc cover 404. The airflow allows for cooling of the cutting disc 403 during operation. Simultaneously, the combined action of the two ports of the manifold 506 and the suction port 507 ensures effective adsorption around the cutting disc 403, facilitating the adsorption of slag generated during cutting. The slag is drawn through the manifold 506 and suction pipe 505 into the collection box 502, where it is retained after filtration by the filter pad 503. Once sufficient slag has been collected in the collection box 502, the pull-out plate 504 can be opened to further filter the slag. The slag collected in the collection box 502 is cleaned. It should be noted that there is a sufficient seal between the collection box 502 and the pull-out plate 504 to prevent air leakage. Therefore, the disc cover 404 can provide protection during cutting. Together with the two ports of the manifold 506 and the air intake 507, it can fully adsorb and collect the slag generated during cutting, thereby achieving simultaneous cutting and slag collection. This prevents the slag generated during cutting from affecting the cutting process, thereby improving cutting efficiency and cutting quality.

[0030] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, symmetrically arranged electric push rods 6 are fixedly installed on the inner side wall of the support frame 1. A clamping plate 7 is fixedly installed at the output end of the electric push rod 6. A production conveying assembly 2 is provided at the inner bottom of the support frame 1. The production conveying assembly 2 includes a conveying seat 201 arranged on the front and rear sides of the support frame 1. A drive motor 202 is fixedly installed on the side wall of the conveying seat 201. A conveying shaft 203 is fixedly connected to the output end of the drive motor 202. A conveyor belt 204 is sleeved on the outer side of the conveyor shaft 203. A positioning cutting hole 205 is opened on the conveyor belt 204. A support collecting assembly 8 is provided on the inner side of the conveyor belt 204. The support collecting assembly 8 includes a support plate 801 fixedly installed on the inner side wall of the support frame 1. A matching hole 802 is opened inside the support plate 801. A carrier box 803 corresponding to the matching hole 802 is detachably installed at the bottom end of the support plate 801.

[0031] By adopting the above technical solution, when it is necessary to cut a MOS package, the MOS package to be cut is placed on the conveyor belt 204, and the position to be cut on the MOS package is aligned with the positioning cutting hole 205 on the conveyor belt 204. After placement, the drive motor 202 is started, and the drive motor 202 drives the conveyor shaft 203 to rotate. It should be noted that the conveyor shaft 203 is divided into a drive shaft and a driven shaft, which are rotatably connected to the conveyor seat 201 respectively. The conveyor shaft 203 can drive the conveyor belt 204 to rotate, thus conveying the MOS package to be cut. When it moves to the position of the clamping plate 7, the conveying stops and starts. The electric push rod 6, when in operation, pushes the symmetrically arranged clamping plates 7 to clamp and fix the MOS package shell, thus ensuring stability during cutting. When the cutting assembly 4 is working, the support plate 801 supports the MOS package, and the matching hole 802 corresponds to the positioning cutting hole 205, allowing some of the slag after cutting to fall into the carrier box 803 through the matching hole 802 and the positioning cutting hole 205. The set support collection assembly 8 can match and cooperate well with the adsorption assembly 5, thus ensuring that the slag generated during cutting is fully processed and avoiding the slag generated during cutting from affecting the cutting process.

[0032] Working principle: When a MOS package needs to be cut, the package is placed on the conveyor belt 204, and the cutting position is aligned with the positioning cutting hole 205 on the conveyor belt 204. After placement, the drive motor 202 is started, which drives the conveyor shaft 203 to rotate. The conveyor shaft 203 consists of a drive shaft and a driven shaft, which are rotatably connected to the conveyor base 201. The conveyor shaft 203 drives the conveyor belt 204 to rotate, thus conveying the MOS package to be cut. When it reaches the clamping plate 7, the conveying stops, and the electric push rod 6 is started. The electric push rod 6 pushes the package to be cut... The clamping plate 7 is used to clamp and fix the MOS package shell, ensuring stability during cutting. When the MOS package needs to be cut, the servo motor 301 is activated, which drives the ball screw 302 to rotate. The ball screw 302 and the ball nut 303 use a conventional ball screw drive, which drives the ball nut 303 and the sliding seat 304 to move left and right in the limiting groove 305. When it moves to the appropriate position, the electric cylinder 306 is activated, which drives the mounting base 308 to slide on the guide rod 307, thus adjusting the height of the cutting assembly 4. When cutting is to be performed, the cutting process is initiated. Motor 401 drives shaft 402 to rotate, which in turn drives cutting disc 403 to cut the MOS package to be processed. Simultaneously, adsorption pump 501 is activated. The adsorption pump 501 creates negative pressure in collection box 502, suction pipe 505, and manifold 506, generating suction through suction port 507 to the inside of disc cover 404. This suction accelerates airflow around disc cover 404, effectively cooling the cutting disc 403. The combined action of the two ports of manifold 506 and suction port 507 ensures the cutting disc... The adsorption effect around 403 facilitates the adsorption of slag generated during cutting by the cutting disc 403. The slag is adsorbed into the collection box 502 through the manifold 506 and the exhaust pipe 505, and retained in the collection box 502 after being filtered by the filter pad 503. When enough slag is collected in the collection box 502, the pull plate 504 can be opened to clean the slag collected in the collection box 502. The support plate 801 supports the MOS package, and the matching hole 802 corresponds to the positioning cutting hole 205. This allows some of the cut slag to fall into the carrier box 803 through the matching hole 802 and the positioning cutting hole 205.It should be noted that controllers, sensors, etc., can be installed on support frame 1 as needed. The controller is electrically connected to drive motor 202, servo motor 301, electric cylinder 306, cutting motor 401, adsorption air pump 501, electric push rod 6, etc. The controller is used to control the operation of each actuator, and photoelectric sensors can be installed on the inner wall of support frame 1 to detect the position of MOS package during transmission. The controller can be pre-programmed with programmable controller to complete the cutting operation of the entire device.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
