DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0022] Embodiment 1: Refer to Figure 1 and Figure 2A laser detection device for laptop casing dimensions includes: a detection stage 1, a movable frame 101, a movable arm 102, a laser detection head 103, a controller, and a microcomputer. It also includes: frame plates 2 symmetrically fixedly connected to the detection stage 1; side plates 201 symmetrically fixedly connected to the detection stage 1, with the two side plates 201 forming a square frame with the two frame plates 2; and a mesh placement assembly disposed between the two frame plates 2. When detecting the casing 6 to be tested, the casing 6 is placed on the mesh placement assembly, the laser detection head 103 scans and detects the casing 6, and the microcomputer records and displays the dimensional results.

[0023] When inspecting the shell 6 to be tested, the shell 6 is placed on the mesh placement assembly and placed in the center as much as possible. Then, the moving frame 101 and the moving arm 102 are moved by the microcomputer and controller. Finally, the laser detection head 103 is used to scan and detect the shell 6 to complete the size detection. The movement of the moving arm 102 and the moving frame 101 is driven by linear motors. The microcomputer is not shown in the figure. The microcomputer is used to display and record the detection data.

[0024] The test housing 6 is placed using a mesh placement component. The mesh component has a certain hollow structure, which can prevent the solder joints of the circuit board mounted on one side of the test housing 6 from falling off and causing scratches on the paint surface of the test housing 6.

[0025] After testing one side of the shell 6 to be tested, it can be flipped over to test the other side.

[0026] Reference Figure 3 The mesh placement component includes multiple support ropes 302 equidistantly arranged between two opposing frame plates 2.

[0027] The support rope 302 is used as the main support component. It has a certain degree of toughness and can prevent bumps and knocks when placing the shell 6 to be tested.

[0028] Example 2: Refer to Figure 5 and Figure 7 A laser detection device for the size of a laptop casing is basically the same as in Embodiment 1. Further, a fixing rod 305 is embedded in the middle of the support rope 302, and soft steel wires 306 are embedded in both ends of the support rope 302. The ends of the soft steel wires 306 are fixedly connected to the fixing rods 305.

[0029] The support rope 302 has an arc-shaped part 303 in the middle, and the two ends of the arc-shaped part 303 are symmetrically provided with placement parts 304.

[0030] By inlaying the fixed rod 305 at the arc-shaped part 303 and inlaying the soft steel wire 306 at both ends of the supporting rope 302, the soft steel wire 306 bears the main load, and the arc-shaped part 303 does not contact the shell 6 to be tested, thereby effectively avoiding the damage of the circuit board inside the notebook shell caused by the friction between the notebook shell and the supporting rope 302.

[0031] With reference to Figure 5 and Figure 6 A first limiting rod 4 is arranged between the plurality of arc-shaped parts 303, and the first limiting rod 4 is arranged on the lower side of the supporting rope 302. The two ends of the first limiting rod 4 are symmetrically fixedly connected with sliding blocks 401. The inner sides of the two side plates 201 are each provided with a limiting sliding groove 203. The sliding blocks 401 are slidingly arranged in the limiting sliding grooves 203. A plurality of second limiting rods 402 are fixedly connected between the plurality of supporting ropes 302. The end portions of the second limiting rods 402 are symmetrically provided with linkage rods 403. The opposite two second limiting rods 402 are rotationally connected with the linkage rods 403. The two ends of the linkage rods 403 are slidingly connected with the frame plate 2. The two ends of the linkage rods 403 are symmetrically provided with rolling balls 404. The end portions of the second limiting rods 402 are slidingly connected with the side plates 201.

[0032] By connecting the plurality of first limiting rods 4 with the arc-shaped parts 303 of the supporting rope 302, the arc-shaped parts 303 can be limited. At the same time, by cooperating the limiting sliding grooves 203 with the sliding blocks 401, the arc-shaped parts 303 can be prevented from shaking forward and backward and horizontally shaking, so that the arc-shaped parts 303 can only move up and down. Then, by limiting the supporting rope 302 with the plurality of second limiting rods 402, the stability of the supporting rope 302 can be ensured, and the supporting rope 302 can be prevented from shaking to affect the laser detection after the shell 6 to be tested is placed.

[0033] By cooperating the arc-shaped parts 303 with the fixed rods 305, only one first limiting rod 4 can be arranged for limiting. If the flexible supporting rope 302 is used, a plurality of second limiting rods 402 are needed for limiting. Since there is a certain friction force between the sliding blocks 401 at the ends of the first limiting rod 4 and the limiting sliding grooves 203 and between the rolling balls 404 of the second limiting rods 402 and the frame plate 2, by arranging one first limiting rod 4, the arrangement of the plurality of second limiting rods 402 can be reduced, so that the total friction force can be reduced, and when the shell 6 to be tested is placed, the shell 6 to be tested can press the supporting rope 302 more quickly, so that the supporting rope 302 can be reasonably supported.

[0034] Even if the center of gravity of the shell 6 to be tested deviates, the first limiting rod 4, the second limiting rod 402 and the linkage rod 403 can cooperate with the supporting rope 302 to stably support the shell 6 to be tested with the deviated center of gravity.

[0035] Embodiment 3: With reference to Figure 3 and Figure 4The notebook computer shell size laser detection device is basically same as that in Embodiment 1, and further, the electric push rod 204 is fixedly connected on the frame plate 2, the telescopic end of the electric push rod 204 is fixedly connected with the positioning plate 205, and the push plate 207 is arranged on the side of the positioning plate 205 away from the electric push rod 204.

[0036] In the specific embodiment, in order to facilitate faster detection of the to-be-detected shell 6, after the to-be-detected shell 6 is placed on the support rope 302 by the staff, the electric push rod 204 is started by manual or by microcomputer, and the preset detailed size of the to-be-detected shell 6 is stored in the microcomputer in advance, the electric push rod 204 is extended by a specified length according to the size of the to-be-detected shell 6, the push plate 207 is pushed to move towards the to-be-detected shell 6, the to-be-detected shell 6 is positioned, and the to-be-detected shell 6 is in the centered position, and under the action of the first limiting rod 4, the second limiting rod 402 and the linkage rod 403, the to-be-detected shell 6 tends to be in a horizontal state, thereby effectively improving the accuracy of detection of the to-be-detected shell 6.

[0037] Reference Figure 5 A plurality of second limiting rods 402 and the support rope 302 are provided with a first placement area 5 and a second placement area 501.

[0038] The first placement area 5 and the second placement area 501 are used to adapt to different sizes of the to-be-detected shell 6, so that the edge of the to-be-detected shell 6 can be placed in the first placement area 5 or the second placement area 501, and the support rope 302 at the first placement area 5 and the second placement area 501 is in a soft state, so that the to-be-detected shell 6 with an arc surface can be horizontally supported by the support rope 302 at the first placement area 5 or the second placement area 501, and the accuracy of laser detection of the to-be-detected shell 6 is improved.

[0039] Reference Figure 4 The notebook computer shell size laser detection device is basically same as that in Embodiment 1, and further, the electric push rod 204 is fixedly connected on the frame plate 2, the telescopic end of the electric push rod 204 is fixedly connected with the positioning plate 205, and the push plate 207 is arranged on the side of the positioning plate 205 away from the electric push rod 204.

[0040] Due to the linkage rod 403, if the staff places the to-be-tested shell 6 is offset to one side, at this time, the to-be-tested shell 6 is in an inclined state, and the interval between the end inclined upward and the electric push rod 204 is relatively smaller than the interval on the other side, at this time, the push plate 207 on the relatively smaller side is first separated from the to-be-tested shell 6, and the push plate 207 is in a downward inclined state, so that a downward force can be applied to the to-be-tested shell 6 to prevent the to-be-tested shell 6 from being lifted to affect its detection, and facilitate the movement and positioning of the to-be-tested shell 6 on the supporting rope 302.

[0041] With reference to Figure 5 , the frame plate 2 is symmetrically provided with a threaded groove 202, the frame plate 2 is provided with a mounting plate 3, the mounting plate 3 is fixedly connected with the frame plate 2 through a locking bolt 301, and the supporting rope 302 is fixedly connected with the mounting plate 3.

[0042] After long-term use, if the outer wall of the supporting rope 302 is seriously worn, the entire net-shaped placing assembly can be replaced by disassembling the locking bolt 301.

[0043] Embodiment 5: With reference to Figure 8 and Figure 9 , the notebook computer shell size laser detection device is basically the same as that in Embodiment 1, and further, when the two ends of the to-be-tested shell 6 are placed at the second placing area 501, the second limiting rod 402 between the first placing area 5 and the second placing area 501 supports the to-be-tested shell 6 through the supporting rope 302, at this time, the lowermost linkage rod 403 is attached to the upper linkage rod 403, and the second limiting rod 402 between the first placing area 5 and the second placing area 501 and the second limiting rod 402 close to the arc-shaped part 303 form a bridging area 502, and at this time, the to-be-tested shell 6 does not contact the supporting rope 302 in the bridging area 502.

[0044] When the size of the to-be-tested shell 6 should be located in the first placing area 5, the arc-shaped part 303 also does not contact the to-be-tested shell 6, so that the contact area of the to-be-tested shell 6 and the supporting rope 302 can be controlled, on the one hand, the wear of the to-be-tested shell 6 can be reduced, and on the other hand, the to-be-tested shell 6 can be positioned.

[0045] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
