[0034] To illustrate the technical solution of the present utility model, the following will be described through specific embodiments, and only the parts related to the embodiments of the present utility model are shown.

[0035] Embodiment:

[0036] As Figures 1-3 shown, the present utility model provides a visual inspection device for a notebook computer housing, including: a frame 1, and a conveying mechanism 2, a rectifying mechanism 3, a photographing mechanism 4, and a light source mechanism 5 provided on the frame 1; the conveying mechanism 2 is used to convey the notebook computer housing to be inspected in a first direction; the rectifying mechanism 3 is located at the top of the front end of the conveying mechanism 2 and is used to rectify the position of the notebook computer housing conveyed on the conveying mechanism 2 in the first direction; the photographing mechanism 4 is located in the middle and rear end of the conveying mechanism 2, and the lens of the photographing mechanism 4 is aligned with the conveying mechanism 2; the photographing mechanism 4 is used to photograph the image of the notebook computer housing conveyed by the conveying mechanism 2; the light source mechanism 5 is located in the middle and rear end of the conveying mechanism 2 and is aligned with the conveying mechanism 2; the light source mechanism 5 is used to cooperate with the photographing mechanism 4 to supplement light for the photographing mechanism 4 when the photographing mechanism 4 takes a picture.

[0037] Specifically, the visual inspection device in this embodiment is used to inspect the notebook computer housing, and this notebook computer housing includes the housing 7 used on the notebook computer screen and the housing 7 used on the notebook computer keyboard. The visual inspection device mainly judges whether it is the housing of the same model of notebook computer through the characters on the top of the notebook computer housing, the shape of the notebook computer housing, and the openings on the side of the notebook computer housing. In this embodiment, mainly the notebook keyboard housing is used as an example for illustration.

[0038] In this embodiment, it includes a frame 1, and a conveying mechanism 2, a rectifying mechanism 3, a photographing mechanism 4, and a light source mechanism 5 provided on the frame 1. The conveying mechanism 2 is used to convey the notebook computer housing that needs to be inspected. The rectifying mechanism 3 is arranged at the top of the front end of the conveying mechanism 2. After the notebook computer housing is placed on the conveying mechanism 2 and conveyed, the notebook computer housing will be rectified in position under the action of the rectifying mechanism 3. After rectification, it is continuously conveyed by the conveying mechanism 2. When the conveying mechanism 2 conveys the notebook computer housing to the middle and rear end, the photographing mechanism 4 takes pictures of the notebook computer housing with the assistance of the light source mechanism 5. After taking pictures, the control mechanism makes an identification and judgment to confirm whether the notebook computer housing is the housing of the same model of notebook computer.

[0039] Next, in combination with Figures 1-3 , the overall structure of the visual inspection device will be introduced in detail.

[0040] As an optional implementation manner, as Figure 1As shown, the frame 1 includes a transverse frame 11 and a longitudinal frame 12, and the transverse frame 11 and the longitudinal frame 12 are fixedly connected. The conveying mechanism 2 and the regularizing mechanism 3 are arranged on the transverse frame 11, the photographing mechanism 4 is arranged on the top of the longitudinal frame 12, and the light source mechanism 5 is arranged on both the transverse frame 11 and the longitudinal frame 12. The frame 1 plays a supporting role in this embodiment, and integrates the conveying mechanism 2, the regularizing mechanism 3, the photographing structure and the light source mechanism 5, so that all the required work can be completed on the frame 1.

[0041] As an alternative embodiment, as Figure 2 shown, the conveying mechanism 2 includes a conveying motor 21 and a conveyor belt 22. The conveying motor 21 and the conveyor belt 22 are in transmission connection and are used to convey the outer shell of the notebook computer to be measured in the first direction. The conveying motor 21 is arranged at the bottom of the transverse frame 11 through a mounting seat 23.

[0042] As an alternative embodiment, the light source mechanism 5 includes a first light source part 51 and a second light source part 52. The first light source part 51 is arranged on the top of the frame 1, and the second light source part 52 is arranged on both sides of the frame 1; the light filling intensity of the first light source part 51 is higher or lower than that of the second light source part 52.

[0043] Specifically, both the first light source part 51 and the second light source part 52 on the light source mechanism 5 are arranged towards the conveying mechanism 2 and are used to cooperate with the photographing mechanism 4 to fill light for the outer shell of the notebook computer conveyed on the conveying mechanism 2 when the photographing mechanism 4 takes pictures. The first light source part 51 is arranged on the top of the longitudinal frame 12 and fills light from top to bottom. In this embodiment, the first light source part 51 can be selected as a flat lamp with a through hole 511 to fill light for the outer shell of the notebook computer on the conveying mechanism 2 from top to bottom. In addition, the first light source part 51 can also be selected as a light bar or a light strip and arranged on the frame beam at the top of the longitudinal frame 12. If the first light source part 51 is selected as a light bar or a light strip, multiple first light source parts 51 can be arranged to ensure its light filling effect. Two second light source parts 52 are arranged and are respectively arranged on both sides of the transverse frame 11 through second mounting brackets 44 arranged on the transverse frame 11 to fill light for the outer shell of the notebook computer from the side. The setting of the light source mechanism 5 can ensure that the photographing mechanism 4 clearly photographs the outer shell of the notebook computer and ensure the accuracy of subsequent comparison.

[0044] As an alternative embodiment, as Figure 1As shown in the figure, the photographing mechanism 4 includes a first photographing unit 41. The first photographing unit 41 is arranged on the top of the frame 1 through a first mounting bracket 43, and the lens of the first photographing unit 41 faces downward and is aligned with the conveying mechanism 2. The first photographing unit 41 is used to photograph the top image of the notebook computer shell conveyed by the conveying mechanism 2. Specifically, the first photographing unit 41 is mounted on the top of the frame through the first mounting bracket 43, and its lens is arranged downward. The first photographing unit 41 is aligned with the conveying mechanism 2 through the through hole 511 on the first light source unit 51. When the conveying mechanism 2 conveys the notebook computer shell to be measured to the position corresponding to the first photographing unit 41, the first photographing unit 41 will take a picture of the notebook computer shell through the through hole 511 under the action of the first light source unit 51 and the second light source unit 52 to obtain the top image of the notebook computer shell. After obtaining the top image, it will be judged under the action of the control mechanism.

[0045] If only the first photographing unit 41 is provided in the vision detection device, the opening condition on the side of the notebook computer shell can still be obtained under the action of the light source mechanism 5, and the subsequent judgment is carried out by the control mechanism. It should be noted that the first light source unit 51 in the light source mechanism 5 fills light from the top, and the second light source unit 52 fills light from the side. The light filling intensities of the first light source unit 51 and the second light source unit 52 are different. If the light filling intensity of the first light source unit 51 is higher than that of the second light source unit 52, a reflection image will appear on the conveyor belt 22 of the conveying mechanism 2 when the notebook computer shell is irradiated by strong light from the first light source unit 51, and the control device can judge the side opening of the notebook computer shell through the reflection image. If the light filling intensity of the first light source unit 51 is lower than that of the second light source unit 52, a shadow will appear when the notebook computer shell is irradiated by strong light from the second light source unit 52, and the control device can judge the side opening of the notebook computer shell through the shadow. Whether the light filling intensity of the first light source unit 51 is higher or lower than that of the second light source unit 52, it can assist the first photographing unit 41 to photograph the top image of the notebook computer shell and judge the side opening of the notebook computer shell for the subsequent control mechanism.

[0046] It should be noted that in this embodiment, setting the first photographing unit 41 can already accurately detect the notebook computer shell. However, in this embodiment, a further description of the second photographing unit 42 is still provided. The photographing mechanism 4 further includes a second photographing unit 42. The second photographing unit 42 is arranged on the side of the frame 1 through a second mounting bracket 44, and the lens of the second photographing unit 42 faces the conveying mechanism 2. The second photographing unit 42 is used to photograph the side image of the notebook computer shell conveyed by the conveying mechanism 2.

[0047] Specifically, as Figure 1As shown in the figure, there are two second photographing units 42, which are respectively arranged on both sides of the horizontal frame 11. The lenses of the second photographing units 42 are all arranged to face the conveying mechanism 2. When the conveying mechanism 2 conveys to the positions corresponding to the first photographing unit 41 and the second photographing unit 42, the first photographing unit 41 and the second photographing unit 42 simultaneously photograph the notebook computer shell. The first photographing unit 41 obtains the top image of the notebook computer shell, and the second photographing unit 42 obtains the side image of the notebook computer shell. It should be noted that when the first photographing unit 41 and the second photographing unit 42 are arranged to simultaneously photograph the notebook computer shell, the supplementary light intensities of the first light source unit 51 and the second light source unit 52 can be the same or different. Whether the supplementary light intensities are the same or different, it will not affect the subsequent judgment of the notebook computer shell. The supplementary light intensities of the first light source unit 51 and the second light source unit 52 are specifically selected according to the actual situation.

[0048] As an optional implementation manner, as Figure 1 shown in the figure, the regularizing mechanism 3 includes a first regularizing part 31 and a second regularizing part 32. The first regularizing part 31 and the second regularizing part 32 are respectively arranged oppositely on the frame 1 through a first support frame 33 and a second support frame 34; the first regularizing part 31 and the second regularizing part 32 are arranged in parallel in the first direction, and the distance between the first regularizing part 31 and the second regularizing part 32 can be adjusted to regularize the notebook computer shells of different models conveyed on the conveying mechanism 2. Specifically, the first regularizing part 31 and the second regularizing part 32 are respectively arranged on both sides of the horizontal frame 11 through the first support frame 33 and the second support frame 34, are suspended at the front end of the conveying mechanism 2, and are arranged oppositely on the frame 1 and in parallel in the first direction, so as to regularize the positions of the notebook computer shells that are not placed neatly conveyed on the conveying mechanism 2, facilitating the subsequent photographing by the photographing mechanism 4.

[0049] As Figure 1 、 Figure 3 shown in the figure, the front ends of the first regularizing part 31 and the second regularizing part 32 are arranged in an open shape. The open-shaped front end facilitates the conveying of the notebook computer shell with a deviation in the placement position under the action of the conveying mechanism 2. After the notebook computer shell is input from the open-shaped front end, it will be regularized under the action of the middle and rear ends of the first regularizing part 31 and the second regularizing part 32, ensuring the accuracy of the position of the notebook computer shell conveyed by the conveying mechanism 2. It should be noted that the distance between the first regularizing part 31 and the second regularizing part 32 can be adjusted on the first support frame 33 and the second support frame 34, and can be adapted to notebook computer shells of different models (the sizes and widths of notebook computer shells of different signals are slightly different), and the adaptability is relatively strong.

[0050] As an alternative embodiment, the vision inspection device further includes a sensing mechanism 6 disposed on the frame 1 and located at the middle front end of the conveying mechanism 2. The sensing mechanism 6 is used to detect the position of the laptop computer housing conveyed by the conveying mechanism 2.

[0051] Specifically, the sensing mechanism 6 provided in the vision inspection device is used to detect the position of the laptop computer housing conveyed by the conveying mechanism 2. As Figure 1 shown, the sensing mechanism 6 is disposed on both sides of the horizontal frame 11 and located at the middle front end of the conveying mechanism 2. After the laptop computer housing conveyed on the conveying mechanism 2 is rectified by the rectifying mechanism 3, it will continue to be conveyed forward. During the conveying process of the laptop computer housing, it passes through the sensing mechanism 6. When the sensing mechanism 6 detects the laptop computer housing, the conveying mechanism 2 will stop, and the photographing mechanism 4 will take a picture. After the photographing is completed, the conveying mechanism 2 will restart and convey the laptop computer housing that has been photographed by the photographing mechanism 4 backward, and cycle in turn to detect all laptop computer housings. It should be noted that the sensing mechanism 6 in this embodiment can be an infrared opposed switch sensor.

[0052] As an alternative embodiment, as Figures 2-3 shown, the vision inspection device further includes a housing 7. The housing 7 is correspondingly provided with a first conveying hole 71 and a second conveying hole 72 in the first direction; the photographing mechanism 4, the light source mechanism 5 and the sensing mechanism 6 are all disposed inside the housing 7 through the frame 1; the conveying mechanism 2 passes through the housing 7 through the first conveying hole 71 and the second conveying hole 72. The conveying mechanism 2 conveys the laptop computer housing into the housing 7 through the first conveying hole 71 for inspection, and outputs it outward through the second conveying hole 72 after the inspection is completed. Specifically, the housing 7 is used to protect the internal photographing mechanism 4, light source mechanism 5 and sensing mechanism 6. While providing protection, it also provides better preconditions for the photographing of the photographing mechanism 4, the supplementary lighting of the light source mechanism 5 and the induction of the sensing mechanism 6 to avoid external interference. The housing 7 is provided with a first conveying hole 71 and a second conveying hole 72 in the first direction. The positions of the first conveying hole 71 and the second conveying hole 72 correspond to each other. The conveying mechanism 2 is disposed through the housing 7 through the first conveying hole 71 and the second conveying hole 72 to convey the laptop computer housing into the housing 7 for inspection, and the computer housing 7 after the inspection is output outward through the second conveying hole 72.

[0053] As an alternative embodiment, as Figure 2As shown in the figure, the visual inspection device further includes a display mechanism 73. The display mechanism 73 is arranged outside the housing 7 and is used to display the states of the conveying mechanism 2, the photographing mechanism 4, and the sensing mechanism 6, and to display the inspection results of the laptop computer housing. Specifically, the display mechanism 73 is a display, which is used for the state information of the conveying mechanism 2, the photographing mechanism 4, the light source mechanism 5, and the sensing mechanism 6, the state information of the laptop computer housing during the inspection process, and the inspection structure of the laptop computer housing. The setting of the display mechanism 73 facilitates the staff to observe the state of the visual inspection device and the results of the corresponding laptop computer housing, which is relatively convenient.

[0054] As an alternative embodiment, as Figures 2-3 shown in the figure, the visual inspection device further includes a warning mechanism 74. The warning mechanism 74 is arranged on the top of the housing 7 and is used to give an alarm when it is detected that the laptop computer housing is unqualified. Specifically, after the photographing mechanism 4 takes an image of the laptop computer housing, the control mechanism will compare the taken image of the laptop computer housing with the set correct image of the laptop computer housing. After the comparison, if the comparison of the laptop computer housing is unsuccessful, the control mechanism will send an unqualified signal to the warning mechanism 74, and the warning mechanism 74 will give a sound or emit light for reminder and warning, so that the staff can record or directly screen, improving the screening efficiency.

[0055] As an alternative embodiment, the visual inspection device further includes a control mechanism. The conveying mechanism 2, the photographing mechanism 4, the light source mechanism 5, the sensing mechanism 6, the display mechanism 73, and the warning mechanism 74 are all connected to the control mechanism. Specifically, the control mechanism is a control component that can start or stop the operation of the visual inspection device. The control mechanism is arranged below the horizontal frame 11 and is arranged in the control housing. The control mechanism includes a visual controller and a light source controller. The visual controller is used to control the photographing mechanism 4 to take pictures, and the light source controller is used to control the light source to emit light. The light source controller can be set separately or can be set in the visual controller. If the light source controller is set in the visual controller, the light source controller will only control the light source mechanism 5 to emit light when the photographing mechanism 4 is taking pictures. If the light source controller is set separately, the light source mechanism 5 will be always on, which will increase the power consumption. Therefore, the light source controller set in this application is set in the visual controller, which can save power consumption and save energy.

[0056] It should be noted that the images of laptop computer housings of different models are pre-recorded in the control mechanism. When it is necessary to inspect laptop computer housings of different models, the control mechanism can quickly switch and inspect laptop computer housings of different models, with a fast switching speed and improved switching efficiency.

[0057] The working principle of the vision detection device described in this embodiment is as follows:

[0058] Place the laptop computer case to be tested on the conveying mechanism 2 for conveyance. While being conveyed, the laptop computer case will be regularized under the action of the regularization mechanism 3, and then be conveyed to the inside of the housing 7 through the first conveying hole 71. First, after the sensing mechanism 6 arranged inside the housing 7 senses that the laptop computer case is conveyed to the designated position, the control mechanism controls the conveying mechanism 2 to convey, controls the light source mechanism 5 to supplement light, and at the same time controls the photographing mechanism 4 to photograph the top image or the top image and the side image of the laptop computer case. After the photographing is completed, the control mechanism controls the conveying mechanism 2 to continue conveying, and at the same time compares the image photographed by the photographing mechanism 4 with the image of the laptop computer case of the same model pre-recorded. If the comparison is successful, the laptop computer case is output outward from the second conveying hole 72 under the action of the conveying mechanism 2. If the comparison is unsuccessful, the control mechanism will send a signal to the warning mechanism 74 for warning to remind the staff to take out the laptop computer case with an unsuccessful comparison. This cycle continues until the detection of all laptop computer cases to be detected is completed.

[0059] The vision detection device in this embodiment is a full-automatic vision detection device. When detecting the laptop computer case, after the photographing mechanism 4 obtains the image of the laptop computer case, subsequent comparison is carried out without manual intervention, and the accuracy rate is higher than that of manual detection. While improving the detection efficiency, the detection quality is also improved.

[0060] The embodiment is only a special case and does not indicate that the present utility model has only such an implementation manner.

[0061] The above are only the preferred embodiments of the present utility model. Those skilled in the art know that without departing from the spirit and scope of the present utility model, these features and embodiments can be variously changed or equivalently replaced. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
