The die cutting system is characterized in that a defective product channel 37 is arranged in a die of the die cutting system 3, the defective product channel 37 is arranged under a defective punch 34, a slide block 38 capable of moving left and right for opening and closing a channel opening is arranged at the upper end of the defective product channel 37, an upper end inclined plane of the slide block 38 is connected with an inclined plane of the telescopic rod 32 through a swing rod 39, and when a defective product runs to a defective product die cutting station, the telescopic rod 32 moves forward to drive the swing rod 39 to rotate clockwise so that the slide block 38 moves backward to open the defective product channel 37. And the good product punching cutter performs punching every time.

The described one-part trimming system embodiment: referring to fig. 15, two main punching cylinders are used to respectively punch unqualified products and qualified products on two small punching dies, and two punching stations act independently to complete respective punching. Because two die-cut stations are relatively independent, maintenance and troubleshooting are more convenient.

The equipment can be wired in a single machine or in an online manner; when single-machine wiring is adopted, a material belt discharging and winding system needs to be provided with a material belt discharging machine to release coiled material belts, and the coiled material belts are introduced into punching and packaging equipment through guide wheels; when on-line wiring is adopted, the material belt after injection molding can be directly led into a die-cutting packaging device through a guide wheel. When online wiring is carried out, if a die on an injection molding machine runs in a double-material belt mode, the matched punching and packaging equipment also needs double-machine wiring; when wiring is carried out by two machines, as shown in fig. 16, the layout mode is divided into a bilateral operation mode and a unilateral operation mode, the bilateral operation mode is that punching packaging equipment is symmetrically arranged along the center line, the operation mode of an operator is similar to that of a single machine, the defect is that the operator needs to walk from one side of the machine to the other side, the unilateral operation mode needs to consider man-machine engineering, two sets of punching packaging equipment are staggered in a mode of being low in front and high in back, operation and maintenance are convenient, the operator does not need to walk from one side to the other side, and operation is convenient.

To further explain the above technical solution, the image detection system 2 is provided with at least 2 image capturing stations, including a first image station located at the front side of the punching system 3 and a second image station located at the rear side of the punching system 3.

The image detection system 2 is mainly composed of a camera, a light source, a reflector, a background, an image analysis unit, a workpiece guiding, fixing and measuring device, a support, an adjusting component and the like. The camera, the light source, the reflector and the background are mutually coordinated to form a multivariable combination, so that an image which is clear in edge outline and beneficial to image analysis is shot. And the image analysis unit is used for automatically comparing the shot image with the standard image by the camera and obtaining a conclusion whether the product is qualified or not through software analysis. The cameras are configured according to the content of image detection required by the product, the number of the cameras is as small as possible, and each camera takes pictures for many times; the material area can stop in the place that needs to shoot under servo motor's drive. The light source adopts polychrome light, and light source position adjustment increases the contrast for the photograph of different positions, if: some pictures require sidelight, some require backlighting, etc. When different shooting characteristics of the same workpiece are adopted, different light configurations are adopted, so that a shot picture has clear edge lines. And the background adopts different backgrounds for metal and plastic parts of the product according to different colors. For example: for metal parts, bright white appears after lighting, a dark background is adopted, the contrast ratio is high, and clear edge lines exist; for the plastic part, because the plastic itself is black, a white background is adopted, the contrast ratio is relatively high, and a clear edge line exists. The improvement of the picture quality plays an important role in improving the precision of an image system. The workpiece guiding, fixing and measuring device mainly comprises a guide groove, a workpiece fixing cylinder, a probe head and the like. Because the material area operation needs the clearance, in the position of shooing, the work piece on the material area is controlled in the spout, but still has about 1 millimeter activity space, causes the upper and lower deviation of work piece position from this, and the picture deviation is great after shooing, and image analysis also consequently the deviation appears, for this reason, before shooing, adopt the cylinder to push down the work piece, has avoided the deviation of work piece upper and lower position, has just also avoided the picture deviation that arouses from this, after shooing, the cylinder loosens, does not influence the operation of material area in the spout. The probe head of the cylinder head can measure important individual overall dimensions and electric conduction and insulation performance of the product, and the relative position of the shot picture after the product is fixed, thereby being beneficial to the analysis and judgment of the picture by a computer; of course, if the probe needed to measure the product is located on another side, an additional air cylinder driven probe or a self-contained driven displacement sensor is needed to detect the size and other properties attached. In addition, the local workpiece photographing position of the guide groove can be provided with a background color for photographing, if the color of the local guide groove meets the requirement of the background color, the guide groove is directly used as the background, otherwise, the background color is required to be added additionally.

The first image station of the image detection system shoots the front side and the left side and the right side by utilizing the distance between the workpieces on the material belt, which is generated due to the injection molding process. According to the specific situation of the workpiece, the angles of the left and right pictures and the number of the pictures are set so as to acquire the surface information of the left and right surfaces of the product, which influences the quality. The second image station of the image detection system can rotate the shot workpiece because the shot workpiece is punched, the camera can shoot the workpieces at different angles relatively statically, as for the installation position of the camera, the surface of the important technical characteristic of the workpiece which is not shot completely is usually selected as a first shooting surface, and the camera is aligned to the first shooting surface at the original position for shooting.

As shown in fig. 17, 18 and 19, the image detection system 2 of the first image station includes a camera 21 and a camera rotating frame, and the camera rotating frame mainly includes a bottom plate 22, a rotating cylinder, an elastic sliding table 23, a sliding shaft pin 24 and an arc-shaped sliding groove 25; the rotary cylinder is fixedly connected below the bottom plate 22, an output shaft of the rotary cylinder penetrates through the bottom plate and is fixedly connected with the elastic sliding table 23, the camera 21 is fixedly connected above a sliding block of the elastic sliding table 23, and the sliding block drives the camera 21 to slide on the elastic sliding table 23; the arc-shaped sliding chute 25 is arranged on the bottom plate 22, and the arc-shaped opening of the arc-shaped sliding chute is opposite to the material belt; the sliding shaft pin 24 is fixedly connected below the front end of the camera, and the sliding shaft pin 24 penetrates through the elastic sliding table 23 and can slide in the arc-shaped sliding groove 25 in a reciprocating manner. The working principle of the image detection system 2 is as follows: when the elastic sliding table is reset under elastic force, the sliding table is at an original position (equivalent to the middle position in the figure), a camera and light bound on the camera are fixed above a sliding block on the elastic sliding table, and a sliding shaft pin is fixed at one end of the sliding block; the sliding shaft pin is connected to the arc-shaped sliding groove on the bottom plate through the bearing, so that the sliding shaft pin can slide along the arc-shaped sliding groove on the bottom plate; and the camera fixed above the sliding block rotates along with the rotating arm of the rotating cylinder and slides along with the sliding block. The camera rotating frame can ensure that the distance between the lens of the camera and the shot workpiece is kept consistent when the camera rotates. When the rotary cylinder is in the middle position, the rotary cylinder is beneficial to keeping the middle position due to the influence of the elasticity of the elastic sliding block, and the positioning of the rotary cylinder can be enhanced by adopting the elastic collision beads; the rotary cylinder can also be replaced by an electric cylinder, or a pneumatic indexing disc or an electric indexing disc. Because of the problem of service life of zoom cameras, cameras with fixed focal lengths are generally adopted in the industry, and therefore, the camera rotating frames are needed, and the design of the arc-shaped sliding groove on the bottom plate needs to consider the movement of the sliding shaft pin so as to drive the lens of the camera to automatically follow the shot workpiece and keep the distance consistent. The shape and the size of the arc-shaped sliding groove of the camera rotating frame in the structure need to be calculated and designed according to actual conditions, and the distance between a lens of the camera and a workpiece is ensured to be consistent when the camera is used for taking pictures every time in the operation process. When the material belt advances to a product to be detected and enters a photographing area of the image detection system 2 at the first image station, a plurality of pictures need to be taken, and then the camera rotating frame is provided with a plurality of stop positions to take a plurality of pictures at a plurality of angles of the same product. Of course, if only one face is to be photographed, the camera can be fixed without using a camera rotating frame.

As shown in fig. 20 and 21, the image detection system 2 of the second image station includes a fixed camera 21 and a workpiece rotation mechanism 26, wherein the workpiece rotation mechanism 26 mainly includes a rotating ring 26-1, a driving wheel 26-2, a plurality of driven wheels 26-3 and a workpiece suction cup 26-4; a driving wheel 26-2 and a plurality of driven wheels 26-3 are uniformly distributed on the outer circumference of the rotating ring 26-1 and are used for driving and limiting the rotating ring 26-1; the rotary ring 26-1 is sleeved on the pneumatic propulsion guide rail 4, and the work is positioned in the axial middle of the rotary ring 26-1; a detection skylight is formed in the side wall of the rotating ring 26-1; the local guide rail of the pneumatic propulsion guide rail 4 positioned in the limiting rotating ring 26-1 can move along with the rotating ring 26-1. The working principle of the image detection system 2 is as follows: on a guide rail for conveying a workpiece, a workpiece rotating mechanism 26 is adopted to fix and rotate the shot workpiece to an angle required to be shot, a sucker or a clamping jaw is arranged on the workpiece rotating mechanism 26, the shot workpiece is firstly sucked or fixed by utilizing the shot surface on the workpiece, and then the shot workpiece is rotated for shooting by a camera, so that the surface required to be shot on the shot workpiece can be conveniently aligned to the camera; according to the shape of the product, if pictures of a plurality of surfaces need to be taken for detection, the rotating mechanism is provided with a plurality of intermediate stop positions, and the last intermediate stop position is used for rejecting defective products. When the shot picture is judged to be unqualified, an unqualified product window on the workpiece rotating mechanism 26 is opened, the sucking disc or the clamping jaw on the workpiece rotating mechanism 26 loosens the shot workpiece, and the shot workpiece falls into a defective product box; when the shot picture is judged to be qualified, the micro rotator is turned back to the original position, and the shot workpiece can be conveyed forwards along the guide rail continuously. Of course, if only one face is to be photographed, the rotating mechanism may not be used.

For the shot after the workpiece is die cut (i.e., the second imaging station), another embodiment is: the guide rail for conveying the workpiece is designed into an S shape (or a spiral shape), the workpiece automatically overturns along the S shape (or the spiral shape) of the guide rail when the S shape (or the spiral shape) guide rail runs, the camera is arranged on a moving frame above or on the side of the guide rail, the moving frame can be driven by an electric ball screw, the PLC controls the movement of the moving frame, the workpiece to be shot is automatically followed, the distance is kept consistent, and multiple times of shooting can be carried out. A shot hole (also called a shooting window) is arranged at a shooting point of the S-shaped (or spiral) guide rail, a shot workpiece is limited in the guide rail and can only slide in the guide rail, and the shot surface of the workpiece can be seen in the shooting window), a stopper is adopted to block the workpiece moving in the guide rail, so that the workpiece is paused, a camera on the movable frame is paused immediately during shooting, the stopper is released after the shooting, the workpiece continues to move forwards, the camera on the movable frame automatically 'follows' the shot workpiece to shoot pictures, the camera returns to the original point after completing one cycle of multi-surface shooting, and the next cycle is ready to be carried out; the stopper can be pneumatic or electric, and is small in size. Software of the image detection system can 'memorize' the position of the shot workpiece and the corresponding picture and automatically analyze defective products; a defective product separating port is also arranged on the S-shaped (or spiral) guide rail, a photoelectric switch is arranged below the defective product separating port, and when the shot workpiece is judged to be a defective product, the defective product separating port on the S-shaped (or spiral) guide rail is automatically opened, and then the defective product is separated out so as not to enter the next packaging step; when the defective product separating port on the guide rail is opened, the photoelectric switch below the defective product separating port receives a signal that a defective product workpiece falls, the equipment operates normally and can continue to operate automatically, if the photoelectric switch does not receive the signal that the defective product workpiece falls, the defective product does not fall into the defective product box, the control system sends out an equipment abnormity alarm pause signal, and after the operation personnel processes the abnormal operation of the equipment is resumed. At the end point of the guide rail, a similar photoelectric switch is also arranged, and when a good-quality workpiece falls, a similar function is achieved. When good products normally fall into the carrier tape or the rectangular disc, the photoelectric switch receives a signal that the good products fall, the equipment normally operates, and the equipment can continuously and automatically operate; otherwise, if the good-quality workpiece does not fall normally, the photoelectric switch does not receive a signal of the good-quality workpiece falling, the control system sends out an equipment abnormity alarm pause signal, and after the operation personnel processes the signal, the normal operation of the equipment is recovered.

The position and the quantity of the cameras on the equipment are designed according to the part detection requirement, if the part is qualified or not only can be judged by shooting one surface, only the first image station needs to be reserved, and the cameras do not need to rotate.
