Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a device for accurately inspecting defective die-cut products, including an inspection platform 101 on which uncut raw materials 102 are placed; it also includes: A cutting component is positioned above the inspection platform 101 and is used for die-cutting operations on uncut raw materials 102; A load-bearing component is installed on the inspection platform 101 for supporting the raw material 102. The inspection platform 101 is provided with a support component for supporting the load-bearing component and the conveying of the raw material 102. In addition, a screening component is installed on the inspection platform 101 for screening abnormal products after die-cutting; It should be noted that during the die-cutting process of raw material 102, through the cooperation of the cutting component, bearing component, support component and inspection component, when the die-cut part is qualified, its thickness matches the height of the height limiting groove 403, and it can pass smoothly through the height limiting groove 403. If there are defective parts such as stacking, they will be blocked by the height limiting groove 403 and cannot continue to move. This inspection method avoids the problems of missed and misjudged judgments in manual visual inspection, and does not require reliance on high-cost testing equipment. While controlling economic costs, it can achieve accurate interception of defects in die-cut parts and ensure the quality of qualified product output.

[0017] The carrying component includes a carrier belt 201, and the raw material 102 is placed above the carrier belt 201 and detachably glued to it by the back adhesive 202. The inspection platform 101 is rotatably connected to the feeding shaft 203 and the receiving shaft 204. The carrier belt 201 and the raw material 102 are wound and connected between the feeding shaft 203 and the receiving shaft 204 after being glued together. The inspection platform 101 is provided with a drive component for driving the receiving shaft 204. It should be noted that the raw material 102 is detachably bonded to the carrier tape 201 and the back adhesive 202. The carrier tape 201 and the raw material 102 are driven and wound together by the feeding shaft 203, the take-up shaft 204 and the drive assembly.

[0018] It is worth noting here that the core function of the drive component is to provide stable torque and speed to the take-up shaft 204 so as to drive the carrier tape 201 and the raw material 102 after bonding to wind between the feed shaft 203 and the take-up shaft 204. Its function and implementation method are mature and widely used in the field of automation equipment. Therefore, it is used as prior art in this application and will not be described in detail here.

[0019] The support assembly includes a first guide roller shaft 302 and a second guide roller shaft 301 rotatably connected above the inspection platform 101. The first guide roller shaft 302 and the second guide roller shaft 301 are located between the feeding shaft 203 and the receiving shaft 204. There is a gap between the feeding shaft 203 and the receiving shaft 204 and the top of the inspection platform 101. The carrier belt 201 and the raw material 102, after being glued and connected, pass through the gap and abut against the feeding shaft 203 and the receiving shaft 204. It should be noted here that the carrier belt 201 is bidirectionally pressed and supported by the first guide roller shaft 302 and the second guide roller shaft 301. On the one hand, this ensures that the carrier belt 201 is flat and wrinkle-free, and avoids the position displacement of the die-cut parts due to the deformation of the carrier belt 201. On the other hand, it enhances the adhesion stability between the die-cut parts and the back adhesive 202.

[0020] The inspection component includes a mounting base 401 fixedly connected to the inspection platform 101. The mounting base 401 is located between the first guide roller shaft 302 and the second guide roller shaft 301. A mounting block 402 is fixedly connected to the mounting base 401. A height limiting groove 403 is formed on the mounting block 402 for the passage of the attached carrier belt 201 and the raw material 102. The height of the height limiting groove 403 matches the height of the attached carrier belt 201 and the raw material 102. It should be noted here that the height limiting groove 403 restricts the passage of the die-cut parts. If the die-cut parts are qualified products, their thickness matches the height of the height limiting groove 403 and they can pass through smoothly. If there are stacked parts, they will be blocked by the height limiting groove 403 and cannot continue to move, thus completing the inspection of defective products.

[0021] The cutting component is located between the inspection component and the first guide roller shaft 302. The cutting component includes a circular knife mold 501 rotatably connected above the inspection platform 101. Multiple sets of blades 502 for cutting the raw material 102 are fixedly connected on the circular knife mold 501. A blade cavity 503 is provided between two adjacent sets of blades 502. It should be noted here that: the drive circular die 501 rotates, and through the two adjacent sets of blades 502 and blade cavity 503, the raw material 102 is die-cut.

[0022] Working principle: During the die-cutting process of raw material 102, the carrier belt 201 with raw material 102 attached is connected between the feeding shaft 203 and the take-up shaft 204. The driving component drives the take-up shaft 204, causing the carrier belt 201 to feed and rewind between the feeding shaft 203 and the take-up shaft 204. During the feeding and rewinding process, the cutting component performs die-cutting on the raw material 102 on the carrier belt 201, and the inspection component performs auxiliary inspection to complete the die-cutting process of raw material 102. During the cutting process, the circular die 501 is driven to rotate, and two adjacent sets of blades 502 act synchronously on the raw material 102 to perform die-cutting. After die-cutting, each individual die-cut part is immediately bonded and fixed by the back adhesive 202 on the surface of the carrier belt 201 to prevent displacement or falling during transportation. However, during the die-cutting process, due to the physical limitations of the die itself, material jamming may occur in the blade cavity 503, causing the entire die-cut part to become embedded in the blade cavity 503 (see reference). Figure 4 When material gets stuck inside the blade cavity 503, during the cutting of the next die-cut part, the die-cut part stuck inside the blade cavity 503 overlaps with the die-cut part of the second cavity, resulting in a defective product with overlapping material (see reference). Figure 5 ); Next, the receiving shaft 204 is driven by the drive component, which moves the carrier belt 201 and the adhered die-cut parts along the feeding direction. When the die-cut parts move continuously with the carrier belt 201 and pass through the height limiting groove 403, if the die-cut parts are qualified products, their thickness matches the height of the height limiting groove 403 and they can pass smoothly. If there is a stacking, it will be blocked by the height limiting groove 403 and cannot continue to move, triggering the device's shutdown protection mechanism. After the operator discovers the shutdown, they can quickly locate the defect location, manually remove the defective products on the carrier belt 201, and then restart the equipment to resume operation. This not only avoids the problem of missed or misjudged judgments by manual visual inspection, but also eliminates the need to rely on high-cost testing equipment. While controlling economic costs, it achieves accurate interception of die-cut part defects and ensures the quality of qualified product output.
