Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 3 This embodiment of a high-precision automatic rejection device includes a support assembly 1. The top of the support assembly 1 is provided with a moving mechanism 2 for forward and backward displacement driven by a driving device. A connecting plate 3 is fixed to the top of the moving mechanism 2. The connecting plate 3 is used to transmit the power of the moving mechanism 2, causing the connecting plate 3 and the secondary linear module 4 on it to move together. The secondary linear module 4 is fixed to the top of the connecting plate 3. A connecting frame 5 is fixed to the output end of the secondary linear module 4. A T-shaped slide rail is fixed to the bottom of the connecting plate 3. The T-shaped slide rail can further improve the stability of the connecting frame 5 when moving. At the same time, the T-shaped slide rail can also play a certain supporting role. The connecting frame 5 is movably connected to the T-shaped slide rail. A winding mechanism 6 for stably winding the tape is provided on the back of the connecting frame 5 and above the secondary linear module 4. An unwinding assembly 7 for releasing the tape is provided on the back of the connecting frame 5 and to the left of the winding mechanism 6. Four fixed pulleys 8 are rotatably connected to the front of the connecting frame 5. The four fixed pulleys 8 are used to ensure that the tape passes smoothly under the telescopic assembly 9. The telescopic assembly 9 is provided on the front of the connecting frame 5 and inside the four fixed pulleys 8.

[0024] In addition, the support assembly 1 consists of a double-leg support frame 101 and a single-leg support frame 102. A stable slide rail is fixed to the top of the single-leg support frame 102. The moving mechanism 2 includes a primary linear module 201 fixed to the top of the double-leg support frame 101. Since the primary linear module 201 is the driving source, the double-leg support frame 101 can provide more stable support force, while the single-leg support frame 102 plays an auxiliary support role to ensure that the slider 202 can move stably. The use of the single-leg support frame 102 can meet the support requirements and reduce the overall weight and volume. The slider 202 is movably connected to the top of the stable slide rail. The output end of the primary linear module 201 and the top of the slider 202 are both fixed to the connecting plate 3.

[0025] In this embodiment, a high-precision camera is also required for visual positioning when installing the device. The camera module can accurately determine the position of the product, thereby determining the coordinates of the defective product and guiding the rejection device to reject the product.

[0026] Please see Figures 1 to 3 To improve the stability and continuity of the conveyor belt, the winding mechanism 6 in this embodiment includes a protective shell 601 fixed to the back of the connecting frame 5. A drive motor 602 is fixed to the front of the connecting frame 5. The drive motor 602 provides reliable and continuous power for the rotation of the driving synchronous pulley 603. The output shaft of the drive motor 602 passes through the connecting frame 5 and extends to the inside of the protective shell 601. The protective shell 601 protects the driving synchronous pulley 603, the driven synchronous pulley 605, and the synchronous belt 606. A transmission part is provided on the outer surface of the output shaft of the drive motor 602 and located behind the connecting frame 5. The transmission part includes a driving synchronous pulley 603 fixed to the outer surface of the output shaft of the drive motor 602. Multiple toothed grooves are provided on both the driving synchronous pulley 603 and the driven synchronous pulley 605. Multiple toothed grooves are fixed to the inner side of the synchronous belt 606. Each tooth has a synchronizing gear, which is matched with the tooth groove. This structure can achieve long-distance transmission and ensure the stability of power transmission. A driven rod 604 is rotatably connected to the front of the connecting frame 5 and above the drive motor 602. A driven synchronous pulley 605 is fixed on the outer surface of the driven rod 604 and at the rear of the connecting frame 5. A synchronous belt 606 is sleeved on the outer surface of the driving synchronous pulley 603. Power is transmitted between the driving synchronous pulley 603 and the driven synchronous pulley 605 through the synchronous belt 606. A recycling disc 607 is fixed on the outer surface of the driving synchronous pulley 603 and at the front of the connecting frame 5. The outer surface of the recycling disc 607 is wrapped with tape. When the recycling disc 607 rotates, it can drive the tape to move, thereby ensuring that the tape under the telescopic component 9 is always in a brand new state, which is convenient for subsequent removal.

[0027] It should be further explained that the outer side of the protective shell 601 is provided with multiple heat dissipation holes, each of which penetrates the side wall of the protective shell 601. The heat dissipation holes facilitate the rapid dissipation of heat inside the protective shell 601. At the same time, the protective shell 601 can ensure a stable connection between the synchronous belt 606 and the driving synchronous pulley 603 and the driven synchronous pulley 605, and avoid external interference.

[0028] In addition, the unwinding assembly 7 includes a support rod 701 fixed to the rear side of the connecting frame 5. A rotating rod 702 is rotatably connected to the front side of the support rod 701 via a bearing. A feed tray 703 is fixed to the outer surface of the rotating rod 702 and located at the front side of the connecting frame 5. Tape is wound on the outer surface of the feed tray 703. When the tape moves, it will drive the feed tray 703 to rotate, thereby releasing more tape. A brake disc 704 is fixed to the rear side of the feed tray 703. An electric push rod 705 is fixed to the front side of the support rod 701. An arc-shaped gripper is fixed to the output end of the electric push rod 705. The arc-shaped gripper is adapted to the brake disc 704. During use, the electric push rod 705 can be controlled to make the arc-shaped gripper fit against the side of the brake disc 704 and maintain a certain pressure. This can increase the friction between the arc-shaped gripper and the brake disc 704, thereby providing a certain rotational damping to the feed tray 703 and smoothly straightening the tape.

[0029] It is known that the telescopic component 9 includes a cylinder 901 fixed to the front of the connecting frame 5. A pressure head 902 is fixed to the output end of the cylinder 901. The cylinder 901 can control the up and down movement of the pressure head 902 to ensure that the tape is successfully attached to the defective product.

[0030] In this embodiment, when not in use, the electric push rod 705 causes the arc-shaped gripper to press tightly against the brake disc 704. The large friction between the two successfully locks the feed tray 703, preventing the feed tray 703 from rotating and causing the tape to loosen when not in use.

[0031] Understandably, the combination of the winding mechanism 6 and the unwinding assembly 7 enables continuous conveying of the tape, thereby improving rejection efficiency. Furthermore, the combination of the primary linear module 201 and the secondary linear module 4 enhances positioning accuracy and overall flexibility.

[0032] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0033] The working principle of the above embodiments is as follows:

[0034] When a vision camera or other vision device detects the specific location of a defective product, the connecting plate 3 is moved back and forth by the primary linear module 201, which in turn moves the pressure head 902. At the same time, the connecting frame 5 is moved left and right by the secondary linear module 4, so that the pressure head 902 can move left and right. When the pressure head 902 is facing the defective product, the cylinder 901 pushes the pressure head 902 down, so that the tape sticks to the defective product. After the defective product is removed, the drive motor 602 drives the active synchronous pulley 603 to rotate, and the synchronous belt 606 transmits the power to the driven synchronous pulley 605. At this time, the driven rod 604 drives the recycling disc 607 to rotate, so as to rewind the tape and move the clean tape under the pressure head 902 for subsequent use.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
