Description

Technical Field

[0001] The present application relates to the technical field of stamping production, and more specifically, to a production control device based on automatic step skipping of visual images. Background Art

[0002] Our company currently produces a small gasket product with adhesive backing, which is made by continuous stamping of adhesive backing rolls. However, in the actual production process, due to defects in the raw materials themselves or on the surface of the materials caused in the previous processing, such as wrinkles, gaps, glue leakage, etc., it is easy to cause glue on the stamping blade, which in turn leads to defective subsequent products of the entire roll. If it is directly stamped and then rejected by manual or visual inspection, the learning difficulty and recognition effectiveness are low because of the presence of complex patterns such as LOGO on the surface of the material. Summary of the invention

[0022] Embodiment 1:

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application discloses a production control device based on automatic step skipping of visual images, including a continuous stamping work platform 1, a material discharge roller 2 is arranged at the front end of the continuous stamping work platform 1, a stamping mechanism 3 is arranged at the rear end of the material discharge roller 2 of the continuous stamping work platform 1, a separation mechanism 4 is arranged at the rear end of the stamping mechanism 3 of the continuous stamping work platform 1, a waste material winding roller 5 is arranged above the separation mechanism 4 of the continuous stamping work platform 1, and a main material winding roller is arranged at the rear end of the separation mechanism 4 of the continuous stamping work platform 1. 6. The scrap material winding roller 5 and the main material winding roller 6 are both connected with drive motors. The continuous stamping work platform 1 is also provided with a front visual inspection unit 7 between the unwinding roller 2 and the stamping mechanism 3. The continuous stamping work platform 1 is also provided with a rear visual inspection unit 8 between the separation mechanism 4 and the main material winding roller 6. The continuous stamping work platform 1 is also provided with a control unit 9. The drive motors of the front visual inspection unit 7, the rear visual inspection unit 8, the stamping mechanism 3, the scrap material winding roller 5 and the main material winding roller 6 are electrically connected to the control unit 9 respectively.

[0025] See also Figure 1 and Figure 3 The front visual detection unit 7 and the rear visual detection unit 8 each include two groups of cameras 10 and a light source 11. The two cameras 10 in the same group are respectively arranged on the front and back sides of the material belt and face the central axis of the material belt. The light source 11 is arranged at the edge of the camera 10.

[0026] Preferably, horizontal guide rollers 12 are provided on both the front and rear sides of the front visual inspection unit 7 , the rear visual inspection unit 8 and the stamping mechanism 3 .

[0027] Preferably, the separation mechanism 4 includes a main separation roller 41, a waste stretching roller 42 and a main material strip stretching roller 43. After punching, the material strip containing waste passes through the main separation roller 41. The waste stretching roller 42 peels off the edge waste strip from the main material strip and guides it to the waste winding roller 5.

[0028] Preferably, the control unit 9 includes a host computer and a PLC controller. The host computer receives image data from the front visual detection unit 7 and the rear visual detection unit 8, compares the received image data with the pre-input image data, and generates a control signal to the PLC controller. The PLC controller controls the stamping action of the stamping mechanism 3 and the winding action of the waste material winding roller 5 and the main material winding roller 6 according to the control signal.

[0029] The implementation principle of a production control device based on automatic step skipping of visual images in the embodiment of the present application is as follows: the material belt passes through the front visual inspection port, and the camera 10 sends the image signal to the control unit 9. The control unit 9 compares the image transmission signal with the pre-stored standard image information. When an abnormality is found on the surface of the material, the area of ​​the abnormal point is calculated, and the distance from the stamping point is calculated in combination with the stamping step gap; then the stamping pulse signal is triggered, and when the defective material reaches the stamping point, the stamping head is paused, and the winding device continues to move forward, so that the defective material continues to be sent forward a stamping spacing. When the defective material passes the stamping point, the stamping head is triggered to start normal stamping; thereby achieving the purpose of avoiding the stamping of defective materials. After avoiding stamping, the defective material will be automatically collected and rolled away as waste material, reducing the difficulty of re-judgment or interference judgment by the subsequent visual inspection; and then the visual inspection unit 8 performs a secondary inspection on the finished product on the main material belt to avoid missed inspections or defects caused by stamping. This solution is particularly suitable for manual material stamping and conventional coil stamping of sheet die-cutting (with adhesive backing or bottom film). Correspondingly, from the perspective of visual inspection, by detecting relatively regular surface defects of raw materials and identifying and picking them out at the front end, it indirectly reduces the difficulty of visual inspection of appearance defects of stamping parts with patterns or LOGO on the surface of the product, ensuring the comprehensive effect of the production line; this visual solution not only solves the appearance problem, but also solves the size detection problem, further ensuring the product production quality.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
