The first sprocket 201 is meshed with the chain 202 on all sides, and the other side of the chain 202 is meshed with the second sprocket 203 on all sides, so that the chain 202 is limited by the installation of the first sprocket 201 and the second sprocket 203. When the stepper motor 29 is driven to rotate the first sprocket 201 clockwise, the chain 202 transmits power to the second sprocket 203, and the second sprocket 203 drives the transmission wheel 204 to rotate accordingly. The transmission wheel 204 transmits the conveyor belt 205 with its own rotation during rotation, so that the conveyor belt 205 rotates around the support frame 206, and the conveyor belt 205 performs corresponding conveying work on the raw materials.

[0019] Further, a plurality of high-brightness LED light strips 207 are fixedly installed in the internal gap of the support frame 206, a fixing frame 24 is fixedly installed on the top of the detection platform 21, a first cylinder 25 is fixedly installed on one side of the top of the fixing frame 24, a first piston rod 26 is movably installed on the output end of the first cylinder 25, a first CCD industrial camera 27 and a second CCD industrial camera 28 are fixedly installed on the top of the detection platform 21, and the first CCD industrial camera 27 and the second CCD industrial camera 28 are electrically connected to the first cylinder 25; In this embodiment, please refer to Figure 3 , Figure 4 By installing the high-brightness LED light bar 207 on the support frame 206, lighting is helpful to ensure that the first CCD industrial camera 27 and the second CCD industrial camera 28 collect images through the optical system during operation. When the first CCD industrial camera 27 and the second CCD industrial camera 28 perform visual inspection, the raw materials transported on the conveyor belt 205 are correspondingly inspected, and the raw materials are screened in a targeted manner. When defective raw materials are detected, an electrical signal is sent to the first cylinder 25 to make it work, and the first cylinder 25 drives the first piston rod 26 at the output end to extend and retract, thereby pushing the raw materials transported on the conveyor belt 205.

[0020] Furthermore, a groove is provided on the top of the detection platform 21, and a collection bin 22 is fixedly installed through the groove, and a collection bucket 23 is placed in the inner cavity of the collection bin 22; In this embodiment, please refer to Figure 3The raw materials pushed by the first piston rod 26 driven by the first cylinder 25 will enter the inner cavity of the collecting bin 22 through the groove provided on the detection platform 21. At this time, the falling raw materials will be collected and processed accordingly by the collecting bucket 23.

[0021] Furthermore, a storage rack 36 is fixedly mounted on the top of the mounting rack 31, and a threaded knob 37 is movably mounted on one side of the storage rack 36, and the threaded knob 37 penetrates and is threadedly connected with a lifting plate 38 adapted thereto; In this embodiment, please refer to Figure 5 The raw materials to be stamped are stored under the installation of the storage rack 36. The bottom of the threaded knob 37 is threadedly connected to the top of the lifting plate 38. When the staff rotates the threaded knob 37 clockwise, the lifting plate 38 performs corresponding lifting activities through the threaded cooperation between the threaded knob 37 and the lifting plate 38, and the gap of the discharge port of the storage rack 36 is controlled accordingly.

[0022] Furthermore, a limit plate 39 is fixedly installed on one side of the storage rack 36 located at the threaded knob 37, and a lifting plate 38 is movably installed through one side of the limit plate 39; In this embodiment, please refer to Figure 5 When the threaded knob 37 and the lifting plate 38 are threadedly matched with each other to make the lifting plate 38 rise and fall, the lifting plate 38 will shake when the threaded knob 37 supports the lifting plate 38 at a single point, thereby affecting the discharge of raw materials from the discharge port of the storage rack 36. When the lifting plate 38 is limited by the limiting plate 39, the lifting plate 38 is ensured to always be lifted vertically and horizontally.

[0023] Furthermore, the positioning punching device 4 also includes a third cylinder 47, the output end of the third cylinder 47 is hinged with a linkage arm 48, and one side of the linkage arm 48 is hinged with a connecting block 49; In this embodiment, please refer to Figure 7 When the third cylinder 47 is driven to work, the piston rod at the output end of the third cylinder 47 drives the linkage arm 48 to move relative to each other. A connecting block 49 is hinged on one side of the linkage arm 48. Under the limit of the connecting block 49, the linkage arm 48 moves in a circle with the hinge of the connecting block 49 as the axis.

[0024] Furthermore, a punch head 46 is fixedly mounted on the other end of the linkage arm 48, and the bottom of the punch head 46 is movably connected to the limited position seat 401; In this embodiment, please refer to Figure 7 When the linkage arm 48 moves in a circle with the connection of the connection block 49 as the axis, one end of the linkage arm 48 generates a linkage with the punch head 46. The punch head 46 rises and falls accordingly with the movement of the linkage arm 48, and the raw material is punched through the groove of the punch channel 44 during the rise and fall.

[0025] Further, a connection channel 41 is fixedly installed on the top of the base 1, a connection block 49 is fixedly installed on the top of the base 1, a limit seat 401 is fixedly installed on the top of the base 1, and a visual servo controller 45 is fixedly installed on the top of the base 1. The visual servo controller 45 is electrically connected to the third cylinder 47; In this embodiment, please refer to Figure 6 , Figure 7 , through the installation of the base 1, the top components are supported accordingly, and the top punch head 46 is limited by the limit seat 401 during support to ensure the stability of the punch head 46 during stamping work. When the bottom of the visual servo controller 45 is positioned to the raw material, an electrical signal is sent to the third cylinder 47 to make it work. Baffles are provided on both sides of the stamping channel 44 to limit the raw material. The punch head 46 pushes the raw material upward to make it contact with the baffle on the stamping channel 44, so that the baffle on the stamping channel 44 and the punch head 46 generate an interactive force to punch the raw material, ensuring that the punch head 46 accurately punches the raw material.

[0026] Working principle: By driving the stepper motor 29 to output the rotational power to the first sprocket 201, the first sprocket 201 transmits the power to the second sprocket 203 through the chain 202, so that the second sprocket 203 links its fixed transmission wheel 204 to rotate the conveyor belt 205. At this time, the material on the top of the conveyor belt 205 is transported along with the movement of the conveyor belt 205. The first CCD industrial camera 27 and the second CCD industrial camera 28 cooperate with each other to detect the material on the top of the conveyor belt 205, and convert the detected target into an image signal, which is transmitted to a dedicated image processing system. The system converts the information into digital signals according to pixel distribution, brightness, color, etc. The image processing system performs various operations on these signals to extract the characteristics of the target, such as area, quantity, position, length, and then outputs the results according to the preset tolerance and other conditions, including size, angle, number, qualified / unqualified, presence / absence, etc., to realize the automatic recognition function. When unqualified raw materials are identified, a signal is sent to the first cylinder 25, so that the first cylinder 25 drives the first piston rod 26 to work, and one end of the first piston rod 26 pushes the raw materials to one side until they fall into the collection bucket 23 and are collected.

[0027] The raw materials are stored by the storage rack 36. When in use, the servo motor 32 is driven to rotate the transmission roller 33 at the output end. At this time, the transmission belt 34 will rotate accordingly when it is limited by the transmission roller 33 and the driven roller 35, so that the top of the transmission belt 34 contacts the raw materials. When the transmission belt 34 rotates, it drives the raw materials to be led out from the discharge port of the storage rack 36, so that the raw materials are delivered to the top of the conveyor belt 205. At the same time, the staff can rotate the threaded knob 37 to threadably match the threaded knob 37 with the lifting plate 38, so that the rotational motion of the threaded knob 37 is converted into the linear motion of the lifting plate 38, and the gap of the discharge port of the storage rack 36 is controlled accordingly to prevent too much raw materials from being taken out at one time.

[0028] The raw materials transported by the conveyor belt 205 will enter the top limit of the connecting channel 41. When the raw materials reach a certain position, the second cylinder 42 is driven to make the second piston rod 43 at the output end perform telescopic movement, and the second piston rod 43 pushes the raw materials into the stamping channel 44. After the raw materials on the stamping channel 44 are positioned by the visual servo controller 45, the third cylinder 47 is driven to link the linkage arm 48, so that the linkage arm 48 moves in a circle with the hinge of the connecting block 49 as the axis, so that the other end of the linkage arm 48 drives the punching head 46 to move upward, and the raw materials are punched with the groove opened in the stamping channel 44.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
