[0002] In the field of automated production, after the product is formed into a finished product on the process production line, the product occasionally does not meet the quality standards, and it needs to go through the finished product quality inspection procedure to identify whether it is a qualified product before it can be packaged and shipped. The currently publicly used finished product inspection forms are relatively diverse. For example, visual inspection equipment can be installed on the product line to detect whether the finished product is qualified. After automatically completing the inspection of each finished product, a conclusion will be formed on whether each product is qualified. Subsequent processes will remove unqualified products based on the conclusion to prevent unqualified products from being mixed with qualified products. In the existing technology, most still use manual methods to remove unqualified products. This method requires more manpower input, heavy manpower load, high labor costs, and manual removal methods are prone to omissions, affecting the quality of shipments; some product production lines use special manipulators to pick out unqualified products from the conveyor line, and this solution is costly. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a defective product rejection device for an automated production line which has a sophisticated structure, is easy to use and has a low cost.

[0004] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0005] The utility model discloses a defective product rejection device for an automated production line, comprising a linear drive mechanism and an action body, the action body is slidably connected to a fixed slide rail, the linear drive mechanism is installed on one side of the slide rail and its movement direction is parallel to the slide rail, the moving terminal of the linear drive mechanism is connected to a resistance body on the side close to the action body, the action body is slidably connected to a trapezoidal block one on the side close to the linear drive mechanism, and the direction of the trapezoidal block one is perpendicular to the movement direction of the linear drive mechanism; the action body comprises a shell, the trapezoidal block one is laterally embedded in the inner side of the shell, the end side of the trapezoidal block one located inside the shell is fixedly connected to one end of a guide rod, and the other end of the guide rod passes through the shell and is connected to a stopper; a spring is provided on a portion of the guide rod located inside the shell; a trapezoidal block two is fixed on the side of the slide rail close to the linear drive mechanism, and the inclined surfaces of the trapezoidal block one and the trapezoidal block two are opposite; a support is fixed on the extended end side of the slide rail, a sliding rod is fixedly connected to the side of the support deviating from the shell, the end of the sliding rod away from the support is slidably embedded in the inner side of the shell, and a spring is provided on a portion of the sliding rod located outside the shell.

[0006] In a possible technical solution, the action body further includes a rejecting head, and the rejecting head is fixedly connected to the outer side of the shell.

[0007] In a possible technical solution, the rejecting head is a rod-shaped head connected to a side of the shell away from the support.

[0008] In a possible technical solution, the linear drive mechanism is a linear motor, and the mover of the linear motor is connected to a resistance body; the linear motor is equipped with a grating encoder connected to the control system signal; the base of the linear motor is provided with two guide rails in parallel, and the mover and the guide rails are slidably matched.

[0009] In a possible technical solution, limit blocks 1 are respectively provided at two ends of the base in the moving direction of the mover.

[0011] A possible technical solution also includes a visual detector arranged on the product conveyor line.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model is used in conjunction with the finished product conveyor line of the automated production line. When defective products appear, the moving terminal of the linear drive mechanism can carry the abutment body to move in the linear direction. The abutment body contacts the trapezoidal block 1 and drives the trapezoidal block 1 to move. Under the limited guiding action of the trapezoidal block 1 and the guide rod, the housing together with the action body slides along the direction of the slide rail under the driving action of the trapezoidal block 1. When the inclined surface of the trapezoidal block 1 reaches the contact position with the inclined surface of the trapezoidal block 2, due to the contact between the inclined surface of the trapezoidal block 1 and the guide rod, the contact body is moved along the direction of the slide rail. Due to the limiting effect of the inclined surface of trapezoidal block 2, trapezoidal block 1 slides toward the inner side of the shell. Under the dual forces of the continuous moving thrust of the moving terminal of the linear drive mechanism and the blocking force of the inclined surface of trapezoidal block 2, trapezoidal block 1 continues to slide toward the inner side of the shell until trapezoidal block 1 breaks away from the resistance body. At this time, under the elastic force of spring 2, the shell and the actuating body are slid and ejected along the direction of the slide rod. Under the action of the ejection force, the actuating body applies a rejection force to the defective products, thereby pushing the defective products out of the finished product conveyor line, completing a rejection process.

[0013] The utility model adopts a mechanical structure to realize the automatic rejection of unqualified products in the finished products of the automated production line, replacing the manual rejection method adopted in the prior art, greatly reducing physical exertion and lowering labor costs. The control system is used to control the rejection action accurately, effectively ensuring the quality of the finished products. The overall device has a sophisticated structure, is easy to use, and has a low cost, and is suitable for transformation and application in automated production lines.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1 As shown, an unqualified product rejection device for an automated production line provided by an embodiment of the utility model comprises a linear drive mechanism 1 and an action body 2, the action body 2 is slidably connected to a fixed slide rail 3, the linear drive mechanism 1 is mounted on one side of the slide rail 3 and its movement direction is parallel to the slide rail 3, a moving terminal of the linear drive mechanism 1 is connected to a resistance body 4 near the action body 2 on one side, a trapezoidal block 5 is slidably connected to the action body 2 on one side near the linear drive mechanism 1, and the direction of the trapezoidal block 5 is perpendicular to the movement direction of the linear drive mechanism 1; the action body 2 comprises a shell 21, the trapezoidal block 5 is laterally embedded in the inner side of the shell 21, the end side of the trapezoidal block 5 located inside the shell 21 is fixedly connected to one end of a guide rod 6, the other end of the guide rod 6 passes through the shell 21 and is connected to a stopper 7; a portion of the guide rod 6 located inside the shell 21 is sleeved with a spring 8; a trapezoidal block 29 is fixed to the side of the slide rail 3 near the linear drive mechanism 1, and the inclined surfaces of the trapezoidal block 5 and the trapezoidal block 29 are opposite; combined Figure 2 , Figure 5 A support 10 is fixed to the extended end side of the slide rail 3, and a slide rod 11 is fixedly connected to the side of the support 10 that is biased towards the shell 21. The end of the slide rod 11 away from the support 10 is slidably embedded in the inner side of the shell 21, and the part of the slide rod 11 located outside the shell 21 is sleeved with a spring 12.

[0022] When the defective product rejection device for the automated production line provided by the utility model is actually implemented, it needs to be installed near the finished product conveying line of the automated production line. The moving terminal of the linear drive mechanism 1 can carry the abutment 4 to move in the linear direction. The initial position of the trapezoidal block 5 is that the outer part of the shell 21 can contact the abutment 4; the abutment 4 can contact the trapezoidal block 5 and drive the trapezoidal block 5 to move. Since the direction of the trapezoidal block 5 is perpendicular to the movement direction of the linear drive mechanism 1, the trapezoidal block 5 is horizontally moved. The housing 21 is embedded in the inner side of the housing 21. Under the limited guiding action of the trapezoidal block 15 and the guide rod 6, the housing 21 together with the action body 2 slides along the direction of the slide rail 3 under the driving action of the trapezoidal block 15. When the inclined surface of the trapezoidal block 15 reaches the contact position with the inclined surface of the trapezoidal block 29, due to the limiting action of the inclined surface of the trapezoidal block 29, the trapezoidal block 15 slides in the inner side of the housing 21. Under the dual action of the continuous moving thrust of the moving terminal of the linear drive mechanism 1 and the blocking force of the inclined surface of the trapezoidal block 29, the trapezoidal block 15 continues to move. Slide toward the inner side of the shell 21 until the trapezoidal block 15 is separated from the abutment body 4. At this time, under the elastic force of the spring 2 12, the shell 21 together with the action body 2 is slid and popped out along the direction of the slide rod 11. The action body 2 applies a rejection force to the defective products under the action of the pop-up force, thereby pushing the defective products out of the finished product conveying line to complete a rejection process. According to conventional technical skills, those skilled in the art can determine that, on the one hand, the pop-up direction of the action body 2 needs to correspond to the conveying direction of the finished product, so that the action body 2 can be popped out to align with the finished product on the conveying line; on the other hand, the device of the utility model can be used in conjunction with the automatic conveying line of the finished product. The finished product conveying line is equipped with a finished product inspection and identification equipment that can immediately inspect whether the quality of the finished product is qualified. The finished product inspection and identification equipment and the linear drive mechanism 1 can be uniformly controlled by the control system. When the finished product inspection and identification equipment identifies it as a defective product, the control system controls the action of the linear drive mechanism 1, and calculates the action position and time to achieve that the pop-up of the action body 2 can be aligned with the target defective product on the conveying line.

[0023] The linear drive mechanism 1 can be a power structure, device or mechanism that can generate reciprocating linear motion; for example, it can include but is not limited to a cylinder, a hydraulic cylinder or an electric push rod; in the present embodiment, specifically, the linear drive mechanism 1 is a linear motor, and the mover 100 of the linear motor is connected to a resistance body 4; the linear motor is equipped with a grating encoder connected to the control system signal, and the real-time movement position of the mover 100 can be accurately controlled; the base 101 of the linear motor is provided with two guide rails 102 in parallel, and the mover 100 slides with the guide rails 102; the base 101 is located at both ends of the moving direction of the mover 100, and limit blocks 103 are respectively provided to ensure that the mover 100 moves within the safe path range of the guide rail 102.

[0024] The direction and height of the abutment body 4 need to be compatible with the direction and height of the trapezoidal block 1 5 so that the abutment body 4 and the trapezoidal block 1 5 can contact each other. As a specific implementation, the shape of the abutment body 4 is a pin-type.

[0025] like Figure 2 As shown, the housing 21 of the action body 2 is a convex block, and a concave groove is provided on the inner side of the slide rail 3. The housing 21 and the inner side of the slide rail 3 can be slidably matched; Figure 3 The trapezoidal block 15 is a right-angled trapezoidal block, the inclined surface of which is arranged on the outer side of the housing 21, combined with Figure 4 The housing 21 corresponds to the position of the trapezoidal block 5 and can open a channel adapted to the sliding action of the trapezoidal block 5. The housing 21 corresponds to the position of the guide rod 6 and opens a through hole adapted to the action of the guide rod 6, thereby realizing the guiding effect. The shape of the stopper 7 is a round cake. After the action body 2 pops out, the trapezoidal block 5 is separated from the resistance body 4. Under the action of the spring 8, the trapezoidal block 5 slides back to the initial position. The control system controls the mover 100 of the linear drive mechanism 1 to move away from the trapezoidal block 29 until the resistance body 4 contacts the trapezoidal block 5. Under the power of the mover 100, the mover 100 is moved back to the initial position. Under the use, the resistance body 4 squeezes the inclined surface of the trapezoidal block 5, so that the trapezoidal block 5 slides toward the inner side of the shell 21, and with the movement of the mover 100, the trapezoidal block 5 retracts so that the resistance body 4 disengages from and passes over the trapezoidal block 5. At this time, under the action of the spring 8, the trapezoidal block 5 slides again to restore to the initial position; the control system can control the mover 100 of the linear drive mechanism 1 to move toward the direction close to the trapezoidal block 29, the resistance body 4 contacts the trapezoidal block 5 and drives the trapezoidal block 5 to move, thereby driving the action body 2 to return to its position, and when the device needs to be rejected again, the rejection process is repeated.

[0026] The trapezoidal block 2 9 is a right-angled trapezoidal block, and the trapezoidal block 2 9 is arranged on the side of the slide rail 3 away from the finished product conveying line.

[0027] Preferably, the action body 2 further includes a rejecting head 22 , which is fixedly connected to the outer side of the shell 21 ; specifically, the rejecting head 22 is a rod-shaped head connected to the side of the shell 21 away from the support 10 .

[0028] Preferably, a second limit block 13 is provided at one end of the slide rail 3 away from the support 10 to prevent the action body 2 from detaching from the slide rail 3 when it pops out.

[0029] Preferably, a visual detector 14 is provided on the product conveying line to check whether the quality of the finished product is qualified and transmit the identification result signal to the control system.

[0030] The unqualified product rejection device for an automated production line of the utility model is installed at a vertical position of the finished product conveyor line of the automated production line when it is working, and the end of the rejection head 22 faces the finished product; the visual detector 14 checks whether the quality of the finished product is qualified, and transmits the identification result signal to the control system; when the visual detector 14 transmits the signal that the identification result is an unqualified product to the control system, the control system sends an action instruction to the linear drive mechanism 1, and the moving terminal of the linear drive mechanism 1 carries the abutment 4 to move along the linear direction, and the abutment 4 contacts the trapezoidal block 5 and drives the trapezoidal block 5 to move. Since the direction of the trapezoidal block 5 is perpendicular to the movement direction of the linear drive mechanism 1, the trapezoidal block 5 is horizontally embedded in the shell 21. On the inner side, under the limited guiding action of the trapezoidal block 15 and the guide rod 6, the housing 21 together with the action body 2 slides along the direction of the slide rail 3 under the driving action of the trapezoidal block 15; when the inclined surface of the trapezoidal block 15 reaches the contact position with the inclined surface of the trapezoidal block 29, due to the limiting action of the inclined surface of the trapezoidal block 29, the trapezoidal block 15 slides toward the inner side of the housing 21, and under the dual action of the continuous moving thrust of the moving terminal of the linear drive mechanism 1 and the blocking force of the inclined surface of the trapezoidal block 29, the trapezoidal block 15 continues to slide toward the inner side of the housing 21 until the trapezoidal block 15 is separated from the abutment body 4. At this time, under the elastic force of spring 2 12, the housing 21 together with the action body 2 is slid and ejected along the direction of the slide rod 11, and the action body 2 exerts a rejection force on the defective products under the action of the ejection force, thereby pushing the defective products out of the finished product conveyor line, completing a rejection process; under the action of spring 1 8, the trapezoidal block 1 5 slides back to the initial position; the control system controls the mover 100 of the linear drive mechanism 1 to move away from the trapezoidal block 2 9 until the abutment 4 contacts the trapezoidal block 1 5, and under the power of the mover 100, the abutment 4 pushes the inclined surface of the trapezoidal block 1 5 The trapezoidal block 15 is squeezed and slides toward the inner side of the shell 21. As the mover 100 moves, the trapezoidal block 15 retracts and causes the abutment 4 to detach and pass over the trapezoidal block 15. At this time, under the action of the spring 18, the trapezoidal block 15 slides again to restore to the initial position. The control system can control the mover 100 of the linear drive mechanism 1 to move toward the direction close to the trapezoidal block 29. The abutment 4 contacts with the trapezoidal block 15 and drives the trapezoidal block 15 to move, thereby driving the action body 2 to return to its original position. When the control system receives the identification signal of unqualified products again, the rejection process is repeated.

[0031] The installation methods, connection methods or setting methods other than those described above are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects; the linear motor and visual detector of the utility model are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
