TECHNICAL FIELD

[0001] The present application relates to the technical field of notebook computer shell laser detection, and particularly to a notebook computer shell size laser detection device. BACKGROUND

[0002] In the production and manufacturing process of a notebook computer, the shell as a key structural component directly affects the assembly quality and use performance of the product. The edge flatness, aperture size, curved surface radian and other parameters of the shell need to strictly meet the design standard, otherwise it may cause the screen to not fit tightly with the body, the interface to be installed out of position and other problems, thereby affecting the overall quality of the product and user experience. Therefore, efficient and accurate size detection of the notebook computer shell is an indispensable link in the production process, and the current detection method commonly used is laser detection.

[0003] In the existing laser detection device, the support structure for placing the notebook computer shell is mostly a rigid platform. When placing the notebook computer shell manually, the inner side of the notebook computer shell has already been installed with a circuit board. On the one hand, double-sided detection is required, and on the other hand, the notebook computer shell may have tin solder points falling off when it is in contact with the rigid platform. Therefore, when detecting the next notebook computer shell, the paint surface may be damaged. In addition, the horizontal rigid platform cannot satisfy the double-sided detection of the notebook computer shell with an arc-shaped side surface. SUMMARY

When detecting a shell to be measured, the shell to be measured is placed on the net-shaped placing assembly, the laser detection head scans and detects the shell to be measured, and the size result is recorded and displayed by the microcomputer.

[0007] Preferably, the net-shaped placing assembly comprises a plurality of support ropes which are arranged equidistantly between the two opposite frame plates.

[0011] In order to facilitate the center positioning of the shell to be tested, further, an electric push rod is fixedly connected on the frame plate, the telescopic end of the electric push rod is fixedly connected with a positioning plate, and the side away from the electric push rod of the positioning plate is provided with a push plate.

[0012] In order to facilitate the detection of the shell to be tested with different sizes and arc-shaped surfaces, preferably, a first placing area and a second placing area are arranged between the second limiting rods and the support ropes.

[0013] In order to facilitate the rapid positioning of the shell to be tested and prevent the shell to be tested from overturning, further, the lower end of the push plate is rotatably connected with the positioning plate, the positioning plate is provided with a through groove, one side of the push plate is fixedly connected with an arc-shaped rod, and the arc-shaped rod is slidingly arranged in the through groove, and an arc-shaped tension spring is fixedly connected between the end of the arc-shaped rod and the positioning plate.

[0014] In order to facilitate the replacement of the support rope, further, screw grooves are symmetrically arranged on the frame plate, an installation plate is arranged on the frame plate, the installation plate is fixedly connected with the frame plate through locking bolts, and the support rope is fixedly connected with the installation plate.

[0015] In order to facilitate the reduction of the contact area of the supporting rope with the to-be-measured shell, further, when both ends of the to-be-measured shell are placed at the second placement area, the second limiting rod between the first placement area and the second placement area supports the to-be-measured shell through the supporting rope, at this time, the lowermost linkage rod is attached to the upper linkage rod, and the second limiting rod between the first placement area and the second placement area and the second limiting rod close to the arc-shaped part form a bridging area, at this time, the to-be-measured shell is not in contact with the supporting rope at the bridging area.

[0018] 2、The notebook computer shell size laser detection device has the fixed rod embedded at the arc-shaped part, and the soft steel wire embedded at both ends of the supporting rope, so that the soft steel wire bears the main load and the arc-shaped part does not contact the to-be-measured shell, thereby effectively preventing the internal circuit board of the to-be-measured shell from being damaged due to friction with the supporting rope.

[0019] 3、The notebook computer shell size laser detection device has a first placement area and a second placement area for accommodating to-be-measured shells of different sizes, so that the edges of the to-be-measured shells can be placed in the first placement area or the second placement area, and the supporting ropes at the first placement area and the second placement area are soft, so that the to-be-measured shells with arc-shaped surfaces can be horizontally supported by the supporting ropes at the first placement area or the second placement area, thereby improving the precision of laser detection of the to-be-measured shells.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 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.

[0033] 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.

[0034] 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.

[0035] After testing one side of the shell 6 to be tested, it can be flipped over to test the other side.

[0036] Reference Figure 3 The mesh placement component includes multiple support ropes 302 equidistantly arranged between two opposing frame plates 2.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] By embedding a fixing rod 305 in the arc-shaped part 303 and embedding soft steel wires 306 in both ends of the support rope 302, the soft steel wires 306 bear the main load-bearing function, and the arc-shaped part 303 does not contact the outer shell 6 under test, thereby effectively avoiding damage to components caused by friction between the inner circuit board of the notebook shell and the support rope 302.

[0041] Reference Figure 5 and Figure 6 A first limiting rod 4 is provided between multiple arc-shaped parts 303, and the first limiting rod 4 is located on the lower side of the support rope 302. The two ends of the first limiting rod 4 are symmetrically fixedly connected to sliders 401. The inner side of the two side plates 201 is provided with a limiting groove 203. The slider 401 is slidably disposed in the limiting groove 203. Multiple second limiting rods 402 are fixedly connected between multiple support ropes 302. The ends of the second limiting rods 402 are symmetrically provided with linkage rods 403. The two opposite second limiting rods 402 are rotatably connected to the linkage rods 403, and the two ends of the linkage rods 403 are slidably connected to the frame plate 2. The two ends of the linkage rods 403 are symmetrically provided with balls 404. The ends of the second limiting rods 402 are slidably connected to the side plates 201.

[0042] By connecting multiple first limiting rods 4 to the arc-shaped portion 303 of the support rope 302, the arc-shaped portion 303 can be limited. At the same time, the cooperation between the limiting groove 203 and the slider 401 prevents the arc-shaped portion 303 from swaying back and forth and horizontally, so that it can only move up and down. Then, multiple second limiting rods 402 limit the support rope 302 to ensure the stability of the support rope 302 and prevent it from shaking after the shell 6 to be tested is placed, thus affecting its laser detection.

[0043] By setting the arc-shaped part 303 to cooperate with the fixed rod 305, only one first limiting rod 4 is needed for limiting. If the flexible support rope 302 is used, multiple second limiting rods 402 are needed for fixing and limiting. Since there is a certain friction between the slider 401 at the end of the first limiting rod 4 and the limiting groove 203, and between the ball 404 of the second limiting rod 402 and the frame plate 2, the setting of one first limiting rod 4 reduces the setting of multiple second limiting rods 402, thereby increasing the total friction. When the shell to be tested 6 is placed, the shell to be tested 6 can press the support rope 302 more quickly, so that the support rope 302 can provide reasonable support.

[0044] Even if the center of gravity of the shell 6 under test shifts, the first limiting rod 4, the second limiting rod 402 and the linkage rod 403 can provide stable support for the shell 6 under test with the shifted center of gravity by cooperating with the support rope 302.

[0045] Example 3: Reference Figure 3 and Figure 4A laser detection device for the size of a laptop casing is basically the same as in Embodiment 1. Furthermore, an electric push rod 204 is fixedly connected to the frame plate 2, and a positioning plate 205 is fixedly connected to the telescopic end of the electric push rod 204. A push plate 207 is provided on the side of the positioning plate 205 away from the electric push rod 204.

[0046] In a specific implementation, to facilitate faster testing of the shell 6 to be tested, after the operator places the shell 6 to be tested on the support rope 302, the electric push rod 204 is manually activated via a switch or controlled by a microcomputer. The microcomputer stores the detailed dimensions of the shell 6 to be tested in advance. Based on the dimensions of the shell 6 to be tested, the electric push rod 204 extends to a specified length, pushing the push plate 207 toward the shell 6 to be tested, positioning the shell 6 to be tested in a centered position. Once the shell 6 to be tested is in a centered position, the shell 6 can be brought to a horizontal state under the action of the first limiting rod 4, the second limiting rod 402, and the linkage rod 403, thereby effectively improving the accuracy of testing the shell 6 to be tested.

[0047] Reference Figure 5 A first placement area 5 and a second placement area 501 are provided between multiple second limit rods 402 and support ropes 302.

[0048] The first placement area 5 and the second placement area 501 are used to accommodate test shells 6 of different sizes, thereby ensuring that the edge of the test shell 6 is placed in the first placement area 5 or the second placement area 501. The support ropes 302 at the first placement area 5 and the second placement area 501 are in a soft state, so that the test shell 6 with an arc surface can be horizontally supported by the support ropes 302 at the first placement area 5 or the second placement area 501, thereby improving the accuracy of laser detection of the test shell 6.

[0049] Example 4: Reference Figure 4 A laser detection device for the size of a laptop casing is basically the same as in Embodiment 1. Further, the lower end of the push plate 207 is rotatably connected to the positioning plate 205. The positioning plate 205 is provided with a through groove 206. An arc-shaped rod 208 is fixedly connected to one side of the push plate 207, and the arc-shaped rod 208 is slidably disposed in the through groove 206. An arc-shaped tension spring 209 is fixedly connected between the end of the arc-shaped rod 208 and the positioning plate 205.

[0050] Due to the linkage rod 403, if the operator places the shell 6 to be tested to one side, the shell 6 will be tilted. The distance between the upward tilted end and the electric push rod 204 will be smaller than the distance on the other side. At this time, the push plate 207 on the side with the smaller distance will disengage from the shell 6 first, and the push plate 207 will be tilted downward. This will apply a downward force to the shell 6 to prevent it from being lifted and affecting the test, while also facilitating the movement and positioning of the shell 6 on the support rope 302.

[0051] Reference Figure 5 The frame plate 2 has symmetrically opened threaded grooves 202, and the frame plate 2 is provided with an installation plate 3. The installation plate 3 is fixedly connected to the frame plate 2 by locking bolts 301, and the support rope 302 is fixedly connected to the installation plate 3.

[0052] If the outer wall of the support rope 302 is severely worn after prolonged use, the entire mesh placement assembly can be replaced by removing the locking bolt 301.

[0053] Example 5: Refer to Figure 8 and Figure 9 A laser detection device for the size of a laptop casing is basically the same as in Embodiment 1. Further, when both ends of the casing 6 to be tested are placed in the second placement area 501, the second limiting rod 402 between the first placement area 5 and the second placement area 501 supports the casing 6 to be tested via a support rope 302. At this time, the lowermost linkage rod 403 is in contact with the upper linkage rod 403, and a bridging area 502 is formed between the second limiting rod 402 between the first placement area 5 and the second placement area 501 and the second limiting rod 402 near the arc-shaped portion 303. At this time, the casing 6 to be tested does not contact the support rope 302 at the bridging area 502.

[0054] When the size of the shell 6 to be tested is located in the first placement area 5, the arc-shaped part 303 does not contact the shell 6 to be tested, thereby controlling the contact area between the shell 6 to be tested and the support rope 302. On the one hand, this can reduce the wear of the shell 6 to be tested, and on the other hand, it is convenient to position the shell 6 to be tested.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
