Description

Technical Field

[0001] The present invention belongs to a detection process for a control panel, and particularly relates to an automatic detection process for a control panel with a window. Background Art

[0002] When detecting the control panels on various existing electrical appliances, only the surface of the control panel can be photographed for detection; for a control panel with a window, that is, a control panel with a semi-transparent effect, when photographing, the light cannot pass through, and the entire control panel is in a black screen state (as Figure 1 shown), therefore, only the front side of the control panel can be detected, while the back side needs to be detected by the operator with the naked eye, resulting in low detection efficiency and prone to incomplete detection. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic detection process for a control panel with a window that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, an automatic detection process for a control panel with a window is provided, including the following steps:

[0005] S1. Automatically convey the control panel coil.

[0006] S2. Collect information on the front and back sides of the control panel in place of conveyance, and compare the collected information with the pre-set information.

[0007] S3. When there are inconsistencies between the collected information and the pre-set information, display them.

[0008] In some embodiments, the control panel coil is placed on an automatic detection device for conveyance and detection. The automatic detection device includes a unwinding mechanism, a winding mechanism, a main machine, an operation table, and an information acquisition device. The control panel sequentially passes through the unwinding mechanism, the information acquisition device, the operation table, and the winding mechanism. The information acquisition device collects information on the front and back sides of the control panel and transmits the collected information to the main machine, and the main machine displays the collected information.

[0009] In some embodiments, the information acquisition device includes a camera, a backlight source, and a front light source, and the camera, the backlight source, and the front light source all act on the passing control panel.

[0010] In some embodiments, the camera is vertically arranged relative to the control panel passing below.

[0011] In some embodiments, the information acquisition device further includes a first reflector and a second reflector. The backlight is located below the camera. The first reflector and the second reflector are inclined and located above the backlight. After the light of the backlight passes through the first reflector and the second reflector upward, it acts vertically on the camera.

[0012] In some embodiments, the front light source is located above one side of the backlight, and the light of the front light source shines downward.

[0013] In some embodiments, the illumination intensity of the backlight is 0 - 150 lux.

[0014] In some embodiments, the automatic detection device further includes an electrostatic elimination device, which is located on the front and back sides of the main body.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. By collecting the front and back information of the control panel and comparing it with the preset information, the front and back of the control panel with a window can be directly and automatically detected, saving manpower and greatly improving the detection efficiency.

[0017] 2. By adding a backlight and a front light source, through the combined action of the two light sources, it is convenient for the camera to obtain the front and back information of the control panel, realizing the detection of the front and back.

[0018] 3. Since the illumination intensity of the backlight is 0 - 150 lux and can reach 150 lux, when detecting the control panel with a window, through the combined action of the front light source and the backlight, when the backlight irradiates on the control panel, the camera can obtain the back information of the control panel, and the control panel will not be completely transparent or opaque, ensuring the normal acquisition of the back information and improving the detection accuracy.

[0019] 4. By providing an electrostatic elimination device, the static electricity on the control panel can be removed, which is beneficial to improving the detection accuracy of the product. Description of the Drawings

[0022] The following further describes the present invention in detail with reference to the drawings.

[0023] The automatic detection process of the control panel with a window of the present invention includes the following steps:

[0024] S1. Automatically convey the control panel coil material;

[0025] S2. Collect information on the front and back of the control panel that has been conveyed in place, and compare the collected information with the pre-set information;

[0026] S3. When there are inconsistencies between the collected information and the pre-set information, display them.

[0027] For the convenience of detection and recording, the information of the control panel with defects can be stored, which is convenient for subsequent tracing of the processing process of the control panel through product defects and is conducive to improving product quality.

[0028] The control panel coil material is placed on the automatic detection device for conveying and detection. The automatic detection device includes an unwinding mechanism, a winding mechanism, a main machine, an operating table and an information acquisition device. The control panel passes through the unwinding mechanism, the information acquisition device, the operating table and the winding mechanism in sequence. The information acquisition device collects the front and back information of the control panel and transmits the collected information to the main machine, and the main machine displays the collected information.

[0029] Among them, the pre-set information at the main machine is the picture information of the front and back of the corresponding control panel when it is correct. When the information obtained by the information acquisition device is inconsistent with the pre-set information, it can be marked and displayed with a red frame or an alarm can be issued in combination with a sound on the display part of the main machine, so as to facilitate the operator to mark the defective control panel at the operating table and detect defective products.

[0030] In actual use, the unwinding mechanism, winding mechanism and operating table in the automatic detection device can adopt the unwinding rack, winding rack and operating table structure in the front and back detection platform with the application number 202223400518.3, which can realize the automatic feeding and winding of the control panel.

[0031] The information acquisition device includes a camera, a backlight source and a front light source, and the camera, backlight source and front light source all act on the passing control panel.

[0032] In the actual detection of the automatic detection process of the control panel with a window of the present invention, through the unwinding mechanism and the winding mechanism, continuous detection of the control panel can be realized. When there is an inconsistency between the front or back information of the control panel photographed by the camera and the information of the corresponding control panel pre-set in the main machine, such as inconsistent patterns, inconsistent characters, or scratches, the operator can mark the corresponding control panel when it passes through the operating table, and the operator can also control the entire automatic detection device to stop, which is convenient for operation.

[0033] The camera is vertically arranged relative to the control panel passing below. Thus, it is convenient to take pictures of the control panel passing below; combined with the settings of the direction and light intensity of the front light source and the back light source, clear picture information can be obtained.

[0034] The information acquisition device further includes a first reflector and a second reflector. The back light source is located below the camera. The first reflector and the second reflector are inclined and located above the back light source. The light of the back light source passes upward through the first reflector and the second reflector and then acts vertically on the camera. Among them, the light intensity of the back light source can be adjusted up to 150 lux. Among them, the first reflector and the second reflector are located between the camera and the back light source.

[0035] The back light source is arranged vertically upward so that the light shines upward. The first reflector and the second reflector are both inclined at 45° in the same direction. After passing through the first reflector and the second reflector, the light finally emitted by the back light source can vertically irradiate the control panel, making the control panel with a window achieve a semi-transparent effect.

[0036] The front light source is located above one side of the back light source, and the light of the front light source shines downward.

[0037] Under the combined action of the front light source and the back light source, the image finally captured by the camera is clear. The horizontal imaging accuracy can reach 0.055 mm / single pixel, the vertical imaging accuracy can reach 0.097 mm / single pixel, and the point defect detection accuracy can reach 0.03 mm 2 . Thus, the image information of the control panel can be clearly compared, and the text part can also be detected to judge whether the text is interrupted or partially missing, and the recognition and detection can be carried out quickly and efficiently.

[0038] During the detection process, the control panel passes directly below the camera. When passing directly below the camera, the camera takes real-time pictures of the control panel and transmits the captured information to the host computer. Through the host computer, the comparison of the control panel information is realized. Since the light of the front light source shines downward, it is convenient to irradiate the control panel, facilitating the camera to obtain the front information of the control panel; since the light intensity of the back light source is 150 lux and is arranged vertically, the light acts vertically on the back of the control panel, making the control panel achieve a semi-transparent effect (as Figure 2 shown), facilitating the camera to obtain the back information of the control panel when taking pictures. Thus, through the front information and the back information obtained by the camera, they can be compared with the pre-set information, and the control panel can be quickly detected.

[0039] The automatic detection device further includes an electrostatic elimination device, which is located on the front and rear sides of the main machine. Among them, the electrostatic elimination device can adopt an ion bar in the prior art, and through the action of electric ions, it can eliminate static electricity on the control panel, greatly reducing static interference during detection and improving detection accuracy.

[0040] During the actual use process, in order to facilitate the centering transportation of the control panel, a deviation rectifying mechanism can be installed between the unwinding mechanism and the camera. Among them, the deviation rectifying mechanism is a common existing deviation rectifying roller to ensure the centering transportation of the control panel.

[0041] The automatic detection process of the control panel with a window of the present invention can achieve high-speed automatic detection of the control panel through automatic unwinding and rewinding; when the control panel is fully transparent, the illumination intensity of the backlight can be adjusted to 0, and only a positive light source is needed; when the control panel is a semi-transparent control panel with a window, through the combined action of the positive light source and the backlight, a semi-transparent effect can be achieved to realize full-automatic detection.

[0042] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
