[0029] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] This embodiment provides a device for detecting the appearance of a notebook shell cover. Figures 1 to 6 As shown, it includes a base 1, a positioning structure, a light source structure and a visual detection mechanism. The base 1 is provided with a cover plate 11. The positioning structure is arranged on the base 1 and includes a positioning component and an adsorption component. The positioning component can move the notebook shell cover to a preset position. The adsorption component can adsorb the notebook shell cover located at the preset position. The adsorption component is provided with an avoidance hole 30. The touchpad mounting hole of the notebook shell cover can face the avoidance hole 30. The light source structure includes a first light source component 4 and a second light source component. The first light source component 4 is arranged opposite to the avoidance hole 30 and includes a first light source body 41. The first light source body 41 is arranged along the four sides of the avoidance hole 30 and the light emitted by it can shine on the inner wall of the touchpad mounting hole. The second light source component includes a second light source body 51. The light emitted by the second light source body 51 can shine on the edges around the notebook shell cover. The visual detection mechanism is located above the base 1 and is configured to be able to capture an image of the notebook shell cover.

[0033] The appearance inspection device for the notebook shell cover provided in this embodiment improves the degree of automation of appearance inspection and increases the inspection speed. The positioning component of the positioning structure can move the notebook shell cover to a preset position, and the adsorption component can adsorb the notebook shell cover on the adsorption component, so that the notebook shell cover will not move relative to the adsorption component. The light emitted by the first light source body 41 of the light source structure can illuminate the inner wall of the touchpad mounting hole, and the light emitted by the second light source body 51 can shine on the edges around the notebook shell cover, so that the visual inspection mechanism can capture the image of the notebook shell cover more clearly, so as to facilitate the appearance inspection of the notebook shell cover and improve the accuracy of the inspection.

[0034] like Figure 2 and Figure 4 As shown, the first light source assembly 4 of this embodiment further includes a shading plate 42 and a flange 43. The shading plate 42 is located above the first light source body 41. At least part of the flange 43 is located below the first light source body 41 and is arranged directly opposite to the first light source body 41. There are multiple first light source bodies 41. The first light source bodies 41 of this embodiment are lamp beads. The obliquely upward light emitted by each first light source body 41 can be irradiated on the inner wall of the touch panel mounting hole. The shading plate 42 and the flange 43 can prevent the light emitted by the first light source body 41 from scattering, so that the light emitted by the first light source body 41 is irradiated on the inner wall of the touch panel mounting hole as much as possible, so that the image of the notebook shell covering the touch panel mounting hole taken by the visual detection mechanism is clearer.

[0035] like Figure 2 and Figure 4 As shown, the first light source assembly 4 of this embodiment further includes a lifting assembly 44 disposed on the base 1, and the first light source body 41 is fixed at the movable end of the lifting assembly 44, and the lifting assembly 44 can drive the first light source body 41 to move in the vertical direction toward or away from the notebook shell cover. After the positioning assembly moves the notebook shell cover to the preset position and the adsorption assembly adsorbs the notebook shell cover, the lifting assembly 44 drives the first light source body 41 to move in the vertical direction toward the direction close to the notebook shell cover, so that the light emitted by the first light source body 41 can be irradiated to the inner wall of the touchpad mounting hole of the notebook shell cover. After the visual detection mechanism captures the image of the notebook shell cover, the lifting assembly 44 drives the first light source body 41 to move in the vertical direction toward the direction away from the notebook shell cover.

[0036] Specifically, Figure 4As shown, the lifting assembly 44 of this embodiment includes a mounting plate 441, a connecting arm 442 and a first linear driving member 443. The mounting plate 441 is arranged on one side of the base 1, the connecting arm 442 is slidably arranged on the mounting plate 441, the fixed end of the first linear driving member 443 is fixedly arranged on the mounting plate 441, the output end of the first linear driving member 443 is connected to one end of the connecting arm 442, and the other end of the connecting arm 442 is provided with a first light source body 41 and can extend into the avoidance hole 30. The lifting assembly 44 is located on one side of the base 1, so that the arrangement of the lifting assembly 44 on the base 1 is more flexible, thereby reducing the requirements of the appearance detection device of the notebook shell cover on the installation space.

[0037] like Figure 2 As shown, the second light source assembly of this embodiment includes a backlight, which is arranged below the second light source body 51. The backlight is used to prevent the light emitted by the second light source from irradiating downward, so that the light emitted by the second light source body 51 is irradiated as much as possible on the edges of the laptop shell cover, so that the visual detection mechanism can clearly capture the image of the edges of the laptop shell cover. Specifically, as Figure 3 As shown, a placement groove 101 is provided on the base 1, and a plurality of light-transmitting holes 102 are provided around the bottom wall of the placement groove 101. The light-transmitting holes 102 are strip holes or arc holes. The adsorption component is arranged in the placement groove 101 and is spaced apart from the side wall of the placement groove 101. The light emitted by the second light source body 51 can pass through the light-transmitting holes 102 and the placement groove 101 in sequence and illuminate the edge of the notebook shell cover. The backlight component is an opaque backlight frame, which is located on the side of the base 1 away from the adsorption component and the backlight component is arranged opposite to the light-transmitting holes 102. The second light source body 51 is clamped between the base 1 and the backlight component.

[0038] like Figure 1 and Figure 3 As shown, the positioning assembly of this embodiment includes two limit block groups 21 and two push components 22. The two limit block groups 21 are arranged on the base 1 and can respectively abut against two side edges arranged adjacent to the notebook shell cover. One limit block group 21 includes a limit block body 211, and the other limit block group 21 includes two limit block bodies 211. The side surfaces of each limit block body 211 that can abut against the notebook shell cover are all arc surfaces. Since there are no edges and corners on the arc surface, when the notebook shell cover abuts against the limit block body 211, the arc surface will not scratch the notebook shell cover, thereby avoiding secondary damage to the notebook shell cover during appearance inspection. Each push component 22 is arranged opposite to a limit block group 21, and the two push components 22 can respectively push the notebook shell cover to a preset position along the first preset direction and the second preset direction, so that the notebook shell cover is limited between the limit block group 21 and the push component 22. Among them, the first preset direction of this embodiment is the length direction of the base 1, and the second preset direction is the width direction of the base 1.

[0039] The positioning structure provided in this embodiment realizes automatic positioning of the notebook shell cover. First, the two pushing components 22 can push the notebook shell cover along the width direction and the length direction of the base 1 respectively, so that the notebook shell cover is limited between the two limit block groups 21 and the two pushing components 22. At this time, the notebook shell cover is located at the preset position of the adsorption component, thereby realizing the preliminary positioning of the notebook shell cover. Then, the adsorption component can adsorb the notebook shell cover, and then realize further positioning of the notebook shell cover, ensuring the accuracy of positioning the notebook shell cover and improving the accuracy of detecting the appearance of the notebook shell cover. In addition, the avoidance hole 30 reserved on the adsorption component facilitates the appearance detection of the touchpad installation hole of the notebook shell cover.

[0040] like Figure 1 As shown, the adsorption component of this embodiment includes a vacuum pump (not shown in the figure) and an adsorption block 31. The adsorption block 31 is provided with a plurality of adsorption holes 310 for adsorbing the notebook shell cover. Each adsorption hole 310 is provided with a suction nozzle 311. The suction nozzle 311 can firmly adsorb the notebook shell cover on the adsorption block 31 so that the notebook shell cover will not move relative to the adsorption block 31. The two limit block groups 21 and the two pushing components 22 are all arranged around the adsorption block 31.

[0041] like Figure 5 As shown, the pushing assembly 22 of this embodiment includes a second linear driving member 221 and two abutting members 222 arranged at intervals. The distribution direction of the two abutting members 222 can be perpendicular to the moving direction of the active end of the second linear driving member 221. The abutting member 222 is arranged at the active end of the second linear driving member 221 and can abut against the side of the notebook shell cover. The axial direction of the abutting member 222 is perpendicular to the plane where the notebook shell cover is located. Specifically, the second linear driving member 221 of this embodiment is a cylinder, which has a simple structure and low production cost, thereby reducing the production cost of the positioning structure. The abutting member 222 of this embodiment is a roller, which includes a hub and a rubber wheel sleeve. The hub is rotatably arranged at the active end of the second linear driving member 221, and the rubber wheel sleeve is sleeved on the hub. Since the rubber wheel sleeve has a certain elasticity, when the rubber wheel sleeve abuts against the notebook shell cover, the notebook shell cover will not be crushed, thereby avoiding secondary damage to the notebook shell cover during appearance inspection. In other embodiments, the number of the abutment members 222 included in each pushing assembly 22 is not limited to two as in the present embodiment, and may also be one or more than two, depending on actual needs.

[0042] like Figure 5As shown, the pushing component 22 of this embodiment also includes a mounting seat 223, a guide member 224, an elastic member (not shown in the figure) sleeved on the guide member 224, and a pushing member 225 provided with abutment member 222. The mounting seat 223 is fixedly connected to the movable end of the second linear drive member 221, and the pushing member 225 is slidably set on the mounting seat 223 along the same direction as the moving direction of the movable end of the second linear drive member 221. One end of the elastic member is connected to the mounting seat 223, and the other end of the elastic member is connected to the pushing member 225. The guide member 224 passes through the mounting seat 223 and is fixedly connected to the pushing member 225. When the second linear driving member 221 drives the abutting member 222 to move toward the direction close to the notebook shell cover, after the abutting member 222 abuts against the notebook shell cover, the second linear driving member 221 continues to drive the abutting member 222 to move toward the direction close to the notebook shell cover, and the pushing member 225 and the abutting member 222 move toward the direction away from the notebook shell cover relative to the mounting seat 223. The abutting member 222 always abuts against the notebook shell cover, the elastic member is compressed, and the force of the abutting member 222 on the notebook shell cover is consistent with the force of the elastic member on the pushing member 225, so that the notebook shell cover is clamped between the abutting member 222 and the limit block body 211. The additional elastic member prevents the notebook shell cover from being damaged again due to excessive force of the abutting member 222 on the notebook shell cover when the second linear driving member 221 drives the abutting member 222 to move toward the direction close to the notebook shell cover.

[0043] like Figure 5 As shown, the pushing member 225 of this embodiment includes a mounting block 2251 and a pushing block 2252. The mounting block 2251 is slidably set on the mounting seat 223. The pushing block 2252 and the mounting block 2251 are fixedly connected by fasteners 2253. When the fasteners 2253 are rotated outward to separate from the pushing block 2252 or the mounting block 2251, the pushing block 2252 can be rotated left or right in a horizontal plane relative to the mounting block 2251 until all the abutting members 222 on the pushing block 2252 abut against the notebook shell cover. Due to the limitation of the positioning structure, the two abutting members 222 of the push assembly 22 may not abut against the notebook shell cover at the same time. The push block 2252 and the two abutting members 222 are rotated leftward or rightward relative to the mounting block 2251 until the two abutting members 222 abut against the side of the notebook shell cover. The push block 2252 and the mounting block 2251 are fixedly connected using fasteners 2253 so that the push block 2252 and the mounting block 2251 do not rotate relative to each other. Figure 5 and Figure 6 As shown, the mounting seat 223 is provided with a slide rail 2231, and the mounting block 2251 is provided with a slider 22511 corresponding to the slide rail 2231. The guide member 224 can push the mounting block 2251 to move along the length direction of the slide rail 2231 relative to the mounting seat 223, so that the abutment member 222 abuts on the notebook shell cover.

[0044] Furthermore, the push block 2252 can rotate to the left relative to the mounting block 2251 with the central axis of the fastener 2253 as the rotation axis at an angle between 0° and 1°, and the push block 2252 can rotate to the right relative to the mounting block 2251 with the central axis of the fastener 2253 as the rotation axis at an angle between 0° and 1°. Figure 6 As shown, a wedge-shaped groove 22510 is provided at one end of the mounting block 2251 that can be connected to the pushing block 2252, one end of the pushing block 2252 can extend into the wedge-shaped groove 22510 and a buffer ring is sandwiched between the two, and the fastener 2253 is arranged through the pushing block 2252, the buffer ring and the mounting block 2251. In other embodiments, the angle at which the pushing block 2252 can rotate leftward and rightward relative to the mounting block 2251 is not limited to the limitation of this embodiment, and can also be other angles, which are specifically set according to actual needs.

[0045] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
