[0002] The 3D inspection device for measuring the side height of mobile phone casings is a specialized instrument for high-precision measurement of the side height parameter of mobile phone casings. With the continuous advancement of mobile phone manufacturing processes, the requirements for dimensional accuracy of mobile phone casings have become increasingly stringent. This device was developed to meet the demand for accurate side height measurement during the mobile phone production process.

[0003] However, the vibrations generated during equipment operation are transmitted to the triangular prism, causing large fluctuations in the image during scanning by the line scanner. It is also necessary to wait for a certain period of time for the triangular prism to stop vibrating before scanning can proceed smoothly. Utility Model Content

[0006] Each of the two longitudinal guide rails is provided with a platform on its upper side to support the product;

[0010] Preferably, a rubber pad is fixedly connected between the two rubber sleeves.

[0011] Preferably, the inner walls of the plurality of rubber sleeves are provided with fitting pads to fill the gap between the rubber sleeves and the triangular prism, and a sealant is provided between the plurality of fitting pads and the triangular prism to restrict the position of the rubber sleeves on the triangular prism.

[0017] Compared with the prior art, this utility model provides a 3D detection device for detecting the side height of a mobile phone casing, which has the following beneficial effects:

[0018] By attaching rubber sleeves to both sides of the triangular prism, the sleeves act as elastic buffers when the device vibrates. When the energy generated by the device vibration is transmitted to the rubber sleeves, the sleeves absorb part of the vibration energy through their elastic deformation, reducing the vibration amplitude transmitted to the triangular prism. When the triangular prism reflects the phone casing, the reflected image is more stable and clear. The stable reflected image provides a solid guarantee for the line scanner to accurately capture detailed information on the side of the phone casing, making subsequent data analysis and processing based on the reflected image more accurate, and ultimately effectively improving the accuracy and reliability of the phone casing side height detection.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The 3D detection device for detecting the side height of a mobile phone casing shown includes a base 1 and two longitudinal guide rails 2 mounted on the upper side of the base 1.

[0026] Each of the two longitudinal guide rails 2 is equipped with a platform 14 on its upper side to support the product;

[0027] A horizontal guide rail 10 is provided on the upper side of the base 1;

[0028] An electric cylinder 7 is installed on the front side of the transverse guide rail 10, and a wire scanning head 6 is installed below the electric cylinder 7. A limit plate 13 is installed between the upper sides of the two longitudinal guide rails 2. A support plate 16 is installed below the two limit plates 13 and near the left and right sides respectively. A triangular prism 18 is installed on the upper side of the two support plates 16. A lifting cylinder 15 is installed inside the two platforms 14 to lift the product and move it up and down. When the equipment is started, the platform 14 moves to the appropriate detection starting position under the guidance of the longitudinal guide rail 2. At this time, the lifting cylinder 15 starts to work. According to the preset program or the operator's instructions, the piston rod extends to lift the product upward, so that the detection part of the product gradually approaches the triangular prism 18. When the predetermined position is reached... When the product reaches a certain height, the lifting cylinder 15 stops moving, completing the product positioning and height adjustment. After the product is positioned, the triangular prism 18 reflects the information of the product's side to a specific direction. The electric cylinder 7 drives the line scanning head 6 to move laterally along the transverse guide rail 10, scanning the product's side information reflected by the triangular prism 18 line by line during the movement of the line scanning head 6. The data analysis system receives the data transmitted from the line scanning head 6, processes and analyzes the data according to the preset algorithm and model. After the line scanning head 6 completes the scanning of the product's side, the electric cylinder 7 drives the line scanning head 6 back to the initial position, the lifting cylinder 15 retracts the piston rod, and lowers the product. The operator removes the inspected product from the platform 14, completing one inspection process.

[0029] Rubber sleeves 19 are fitted on both sides of the two triangular prisms 18. The rubber sleeves 19 on both sides of the triangular prisms 18 effectively reduce vibration interference, and the reflected image is stable and clear.

[0030] like Figure 4 As shown, a rubber pad 20 is fixedly connected between two rubber sleeves 19, and a fitting pad 21 is provided on the inner wall of multiple rubber sleeves 19 to fill the gap between the rubber sleeves 19 and the triangular prism 18. A sealant 22 is provided between multiple fitting pads 21 and the triangular prism 18 to restrict the position of the rubber sleeves 19 on the triangular prism 18. The multiple rubber sleeves 19 and the support plate 16 are also fixedly connected by sealant 22.

[0031] When the equipment vibrates, the rubber pad 20 can transmit and disperse vibration energy between the two rubber sleeves 19, preventing the individual rubber sleeve 19 from bearing excessive stress. The bonding pad 21 has good flexibility and plasticity, and can adaptively adjust according to the surface shape of the triangular prism 18, ensuring that the rubber sleeve 19 and the triangular prism 18 fit tightly without gaps. The sealant 22 fills the tiny gaps between the bonding pad 21 and the surface of the triangular prism 18, increases the adhesion between the two, restricts the position of the rubber sleeve 19 on the triangular prism 18, and prevents the rubber sleeve 19 from being displaced due to vibration or other external forces.

[0032] like Figure 1As shown, the rear outer walls of the two longitudinal guide rails 2 are each provided with a first driver 5 to drive the platform 14 to move back and forth under the restriction of the longitudinal guide rails 2. The rear outer wall of the transverse guide rail 10 is provided with a second driver 11 to drive the electric cylinder 7 to move left and right under the restriction of the transverse guide rail 10.

[0033] After the product is placed on the stage 14, the control system sends a command to the first driver 5 again according to the detection process. The stage 14 moves back and forth on the longitudinal guide rail 2 at a preset speed and path, transporting the product to different detection positions. After the stage 14 moves the product to the corresponding detection position, the control system sends a command to the second driver 11. The electric cylinder 7 drives the line scanning head 6 to move left and right on the transverse guide rail 10 at a set speed, scanning the side information of the product reflected by the triangular prism 18 during the movement of the line scanning head 6.

[0034] like Figure 1 and Figure 2 As shown, a base support 9 is fixedly connected to the upper outer wall of the electric cylinder 7 to limit the position of the electric cylinder 7 and the line scanning head 6. Multiple fixed legs 3 are fixedly connected between the four corners of the lower outer wall of the limiting plate 13 and the base 1 to limit the position of the limiting plate 13. A through hole 12 is opened inside the upper outer wall of the limiting plate 13 so that the line scanning head 6 can capture the image reflected by the triangular prism 18. A connecting rod 17 is provided between the two support plates 16 and the limiting plate 13 to limit the position of the support plates 16.

[0035] The base 9 is tightly connected to the electric cylinder 7, providing additional support and positioning for the electric cylinder 7 and preventing it from shaking or shifting during movement. The fixed leg 3 securely connects the limiting plate 13 to the base 1, providing vertical support for the limiting plate 13 so that it does not move up or down during equipment operation. The position and size of the through hole 12 are precisely designed to ensure that the optical axis of the line scanning head 6 can be aligned with the path of the light reflected by the triangular prism 18 through the through hole 12 as the line scanning head 6 moves along the transverse guide rail 10.

[0036] like Figure 1 As shown, a fixing bracket 4 is provided on the upper outer wall of the base 1 and near the left and right sides respectively to limit the height of the transverse guide rail 10. A fixing plate 8 is provided between the two fixing brackets 4 and the transverse guide rail 10 to limit the position of the transverse guide rail 10.

[0037] Place the transverse guide rail 10 on the base 1 and restrict its height position by the fixing bracket 4 to ensure that the transverse guide rail 10 is at the design required height. Then, install the fixing plate 8 between the fixing bracket 4 and the transverse guide rail 10 and fix the fixing plate 8 to fix the transverse guide rail 10 in the horizontal direction and prevent it from shifting.

[0038] The implementation principle of this embodiment is as follows: Upon starting the equipment, the platform 14, guided by the longitudinal guide rail 2, moves to a suitable initial detection position. At this time, the lifting cylinder 15 begins operation, extending its piston rod according to a preset program or operator instructions, lifting the product upwards so that the detection area of ​​the product gradually approaches the triangular prism 18. When the predetermined height is reached, the lifting cylinder 15 stops, completing the product positioning and height adjustment. After product positioning is complete, the triangular prism 18 reflects the information from the side of the product to a specific direction, and the electric cylinder 7 drives the wire scan head 6 to move laterally along the transverse guide rail 10. The scanning head 6 moves while the triangular prism 18 reflects the product's side information line by line. The analysis system receives the data transmitted from the scanning head 6 and processes and analyzes the data according to the preset algorithm and model. After the scanning head 6 completes the scanning of the product's side, the electric cylinder 7 drives the scanning head 6 back to the initial position, and the lifting cylinder 15 retracts the piston rod to lower the product. The operator takes the inspected product from the platform 14, completing one inspection process. The rubber sleeves 19 on both sides of the triangular prism 18 effectively reduce vibration interference, and the reflected image is stable and clear.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
