Description

Technical Field

[0001] This utility model relates to the field of concentricity detection technology, specifically to a light source angle adjustment mechanism and a concentricity detection device. Background Technology

[0002] In the current smartphone manufacturing industry, the quality of mobile phone cameras is directly related to the user's photography experience and the overall performance of the device. Among them, camera concentricity, as one of the important indicators for measuring the precision of camera assembly, has a crucial impact on image quality. Therefore, existing technologies use visual inspection to confirm whether the camera concentricity is up to standard.

[0003] To facilitate clearer image capture by the camera used in visual inspection, a light source is usually provided. However, the adjustment of the light source angle in existing technologies is relatively limited, which is not conducive to use. Therefore, we propose an improvement, namely a light source angle adjustment mechanism and a concentricity detection device. Utility Model Content

[0004] This utility model provides a light source angle adjustment mechanism, including a connecting seat, an adjustment structure connected to the connecting seat, and a light source support arm located on one side of the connecting seat. The light source support arm has a receiving groove. A first hand-tightening bolt is bolted to the connecting seat and passes through the receiving groove. A second hand-tightening bolt is inserted and connected to the light source support arm. A fastening nut is threaded onto the second hand-tightening bolt and welded to the outer side of the light source support arm. A light source structure is provided on the outer surface of the second hand-tightening bolt, and one end of the light source structure is located in the receiving groove.

[0005] After loosening the first hand-tightening bolt, the light source support arm can be rotated around the first hand-tightening bolt, and the light source support arm can be raised and lowered, thereby adjusting the angle and height of the light source structure. After loosening the second hand-tightening bolt, the light source structure can be rotated around the second hand-tightening bolt to adjust the angle between the light source structure and the light source support arm, increasing the adjustment range. The adjustment process can be done by hand, which is convenient to use. Before installation and use, the light source structure can be rotated in the receiving groove, making the adjustment structure and the light source structure more compact. The adjustment structure can also provide some protection for the light source structure.

[0006] Specifically, through a dual adjustment design of "first hand-tightening bolt + lifting / rotation of the light source support arm" and "second hand-tightening bolt + rotation of the light source structure," the three-dimensional adjustment of the light source structure's "height + angle with the connecting seat + angle with the light source support arm" is achieved. Compared with a single angle adjustment mechanism, this can cover more lighting needs. Because the cooperation between the first hand-tightening bolt and the receiving groove provides a fulcrum for lifting and rotation, and the second hand-tightening bolt provides an independent rotation fulcrum for the light source structure, the two independent fulcrums break the limitation of a single adjustment dimension, making the position and angle adjustment of the light source structure more flexible.

[0007] Manual operation lowers the barrier to entry and reduces efficiency costs. No tools are needed; adjustments can be made simply by hand-tightening the first and second bolts. This reduces the hassle of finding tools and shortens adjustment time. For example, during production line inspection, workers do not need to stop to find tools; they can quickly adjust the light source structure by tightening the bolts, thus improving overall work efficiency.

[0008] As a preferred technical solution of this application, a bolt washer is provided on the outer surface of the first hand-tightening bolt. The bolt washer abuts against the side of the light source support arm away from the connecting seat. The bolt washer can increase the contact area of ​​the first hand-tightening bolt, thereby improving the fixing effect of the first hand-tightening bolt on the light source support arm when tightened. Because the bolt washer increases the contact area with the light source support arm, it disperses the pressure when the first hand-tightening bolt is tightened, reduces the deformation of the surface of the light source support arm caused by pressure concentration, and at the same time increases the friction. It also makes the clamping force of the first hand-tightening bolt on the light source support arm more uniform and the fixing effect better.

[0009] As a preferred technical solution of this application, the light source structure includes a first protective shell with one end inserted into the receiving groove. The first protective shell is sleeved on the outer surface of the second hand-tightening bolt. A lamp holder is installed inside the first protective shell, and a supplementary light is connected to the lamp holder. After the second hand-tightening bolt is loosened, the first protective shell can rotate around the second hand-tightening bolt. The first protective shell encloses the lamp holder and the supplementary light, which can play a protective role.

[0010] As a preferred technical solution of this application, a second protective shell is installed on one side of the first protective shell by bolts. The second protective shell is sleeved on the outer surface of the second hand-tightened bolt. A viewing window is provided on the upper part of the second protective shell, and a transparent protective plate is fixedly installed inside the viewing window. The transparent protective plate is fixed inside the viewing window by adhesive. Adding a second protective shell on the basis of the first protective shell forms a "double protection" structure, which can improve the protection effect on the lamp holder and the supplementary light.

[0011] The transparent protective panel is made of acrylic material, which not only does not affect the light output of the supplementary lighting, but also reduces the entry of foreign objects into the interior through the viewing window of the second protective shell.

[0012] A concentricity detection device using a light source angle adjustment mechanism includes a support frame with a mounting base bolted to it. A connecting base is fixedly connected to the side of the mounting base and welded to it. A camera is mounted on the mounting base and bolted to it. The light source structure is located on the side of the camera. This allows the light source structure to provide supplementary lighting for the mobile phone, thereby enabling the camera to capture clearer information from the mobile phone camera.

[0013] As a preferred technical solution of this application, the support frame has several vertically arranged long slots for bolts to pass through, which are used to connect the support frame and the mounting base. The long slots allow the height of the mounting base to be adjusted, thereby enabling the adjustment of the height of the camera, adjustment structure, and light source structure. Specifically, by loosening the bolts and moving the mounting base up and down along the long slots, the height of the camera and light source structure can be adjusted to accommodate objects of different heights. When the height of the mounting base is adjusted, the camera, light source structure, and adjustment structure move synchronously, which is more convenient.

[0014] As a preferred technical solution of this application, a base plate is installed at the bottom of the support frame, and the base plate is fixed to the support frame by bolts. The base plate is provided with a number of mounting holes, which are arranged so that the base plate can be installed on the supported object by bolts, such as on a workbench.

[0015] As a preferred technical solution of this application, a mobile phone positioning seat corresponding to the position of the mounting base is installed on the top of the base plate. The top of the mobile phone positioning seat is provided with a mobile phone positioning groove. The mobile phone positioning seat is installed on the top of the base plate by bolts. This arrangement allows the mobile phone positioning seat to be disassembled and replaced. Specifically, the size of the mobile phone positioning groove is adapted to the mobile phone to be tested, reducing the testing error caused by the deviation of the mobile phone's placement angle, front-back and left-right positions during each test. The mobile phone positioning seat is connected to the base plate by bolts. When it is necessary to test mobile phones of different models and sizes, it is not necessary to replace the entire concentricity testing device. Only the bolts need to be removed and the corresponding specification of the mobile phone positioning seat needs to be replaced.

[0016] As a preferred technical solution of this application, the top of the mobile phone positioning base is also provided with a mobile phone retrieval slot, and the mobile phone retrieval slot is connected to the mobile phone positioning slot. The setting of the mobile phone retrieval slot can provide operating space for fingers when picking up and putting down the mobile phone. After the mobile phone is placed in the mobile phone positioning slot, the edge of the phone body will be partially exposed in the mobile phone retrieval slot. The staff can insert their fingers into the mobile phone retrieval slot and easily pinch the edge of the mobile phone to take it out, reducing the "difficulty in taking out the phone" caused by the mobile phone being too tightly attached to the mobile phone positioning slot.

[0017] As a preferred technical solution of this application, a computer bracket is installed on the top of the support frame. The computer bracket and the top of the support frame can be connected by bolts or welding. An industrial computer is installed on the computer bracket and is connected to the computer bracket by bolts. An image acquisition card is connected between the industrial computer and the camera. The industrial computer receives the detection image captured by the camera through the image acquisition card and can analyze the image in real time to realize the detection of the concentricity of the mobile phone camera. The detection principle is the existing technology.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] This application, through its adjustable structure, allows the light source support arm to be rotated around the first hand-tightened bolt after loosening it, and also allows for raising and lowering of the light source support arm, thereby adjusting the angle and height of the light source structure. Loosening the second hand-tightened bolt allows the light source structure to be rotated around the second hand-tightened bolt to adjust the angle between the light source structure and the light source support arm, increasing the adjustment range. The adjustment process can be performed manually, making it easy to use. Furthermore, before installation and use, the light source structure can be rotated into the receiving slot, making the adjustable structure and light source structure more compact. The adjustable structure also provides some protection for the light source structure. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1, please refer to Figures 1-6 A light source angle adjustment mechanism includes a connecting seat 6, an adjustment structure 1 connected to the connecting seat 6, and a light source support arm 103 located on one side of the connecting seat 6. The light source support arm 103 has a receiving groove 107. A first hand-tightening bolt 102 is bolted to the connecting seat 6 and passes through the receiving groove 107. A second hand-tightening bolt 105 is inserted and connected to the light source support arm 103. A fastening nut 106 is threaded onto the second hand-tightening bolt 105 and welded to the outer side of the light source support arm 103. A light source structure 2 is provided on the outer surface of the second hand-tightening bolt 105, and one end of the light source structure 2 is located in the receiving groove 107.

[0033] After loosening the first hand-tightening bolt 102, the light source support arm 103 can be rotated around the first hand-tightening bolt 102 as the center, and the light source support arm 103 can also be raised and lowered, thereby adjusting the angle and height of the light source structure 2. After loosening the second hand-tightening bolt 105, the light source structure 2 can be rotated around the second hand-tightening bolt 105 as the center, so as to adjust the angle between the light source structure 2 and the light source support arm 103, thereby increasing the adjustment range. The adjustment process can be done by hand, which is convenient to use. Before the adjustment structure 1 and the light source structure 2 are installed and used, the light source structure 2 can be rotated in the receiving groove 107, making the adjustment structure 1 and the light source structure 2 more compact. The adjustment structure 1 can also provide some protection for the light source structure 2.

[0034] Specifically: Through the dual adjustment design of "first hand-tightening bolt 102 + light source support arm 103 lifting / rotating" and "second hand-tightening bolt 105 + light source structure 2 rotation", the three-dimensional adjustment of the light source structure 2 in "height + angle with connecting seat 6 + angle with light source support arm 103" can be achieved. Compared with a single angle adjustment mechanism, it can cover more lighting needs. Because the cooperation between the first hand-tightening bolt 102 and the receiving groove 107 provides a lifting and rotation fulcrum, and the second hand-tightening bolt 105 provides an independent rotation fulcrum for the light source structure 2, the two independent fulcrums break the limitation of a single adjustment dimension, making the position and angle adjustment of the light source structure 2 more flexible.

[0035] The manual operation reduces the barrier to entry and efficiency costs. No tools are needed; adjustments can be made simply by hand-tightening the first bolt 102 and the second bolt 105. This reduces the hassle of finding tools and shortens the adjustment time. For example, during production line inspection, workers do not need to stop to find tools; they can quickly adjust the light source structure 2 by tightening the bolts, thus improving overall work efficiency.

[0036] Furthermore, a bolt washer 104 is fitted on the outer surface of the first hand-tightened bolt 102. The bolt washer 104 abuts against the side of the light source support arm 103 away from the connecting seat 6. The bolt washer 104 increases the contact area of ​​the first hand-tightened bolt 102, thereby improving the fixing effect on the light source support arm 103 when the first hand-tightened bolt 102 is tightened. Because the bolt washer 104 increases the contact area with the light source support arm 103, it disperses the pressure when the first hand-tightened bolt 102 is tightened, reduces the deformation of the surface of the light source support arm 103 caused by pressure concentration, and at the same time increases the friction. It also makes the clamping force of the first hand-tightened bolt 102 on the light source support arm 103 more uniform and the fixing effect better.

[0037] Furthermore, the light source structure 2 includes a first protective housing 201 with one end inserted into the receiving groove 107. The first protective housing 201 is sleeved on the outer surface of the second hand-tightening bolt 105. A lamp holder 204 is installed inside the first protective housing 201, and a supplementary light 205 is connected to the lamp holder 204. After loosening the second hand-tightening bolt 105, the first protective housing 201 can rotate around the second hand-tightening bolt 105. The first protective housing 201 encloses the lamp holder 204 and the supplementary light 205, thus providing protection.

[0038] Furthermore, a second protective housing 202 is bolted to one side of the first protective housing 201. The second protective housing 202 is fitted onto the outer surface of the second hand-tightening bolt 105. A viewing window is provided on the second protective housing 202, and a transparent protective plate 203 is fixedly installed inside the viewing window. The transparent protective plate 203 is glued to the viewing window. By adding the second protective housing 202 to the first protective housing 201, a "double protection" structure is formed, which can improve the protection effect on the lamp holder 204 and the supplementary light 205.

[0039] The transparent protective plate 203 is made of acrylic material, which not only does not affect the light emitted by the supplementary light 205, but also reduces the entry of foreign objects into the interior through the viewing window of the second protective shell 202.

[0040] Example 2, please refer to Figures 1-6 A concentricity detection device using a light source angle adjustment mechanism includes a support frame 301, a mounting base 303 connected to the support frame 301 by bolts, a connecting base 6 fixedly connected to the side of the mounting base 303 and welded together with the mounting base 303, a camera 304 mounted on the mounting base 303 and connected to the mounting base 303 by bolts, and a light source structure 2 located on the side of the camera 304; this allows the light source structure 2 to provide supplementary lighting for the mobile phone, thereby enabling the camera 304 to capture clearer information from the mobile phone camera.

[0041] Furthermore, the support frame 301 has several vertically arranged long cable openings 302, through which bolts for connecting the support frame 301 and the mounting base 303 pass. The long cable openings 302 allow the height of the mounting base 303 to be adjusted, thereby enabling the adjustment of the height of the camera 304, the adjustment structure 1, and the light source structure 2. Specifically, by loosening the bolts and moving the mounting base 303 up and down along the long cable openings 302, the height of the camera 304 and the light source structure 2 can be adjusted, accommodating objects of different heights. When the height of the mounting base 303 is adjusted, the camera 304 moves synchronously with the light source structure 2 and the adjustment structure 1, making it more convenient.

[0042] Furthermore, a base plate 3 is installed at the bottom of the support frame 301. The base plate 3 is fixed to the support frame 301 by bolts. The base plate 3 is provided with several mounting holes. The mounting holes are provided so that the base plate 3 can be installed on a support object by bolts, such as on a workbench, so that the existing support object can provide support for this application and meet the usage requirements.

[0043] Furthermore, a mobile phone positioning seat 4 corresponding to the position of the mounting base 3 is installed on the top of the base plate 3. The top of the mobile phone positioning seat 4 is provided with a mobile phone positioning groove 401. The mobile phone positioning seat 4 is installed on the top of the base plate 3 by bolts. This arrangement allows the mobile phone positioning seat 4 to be disassembled and replaced. Specifically, the size of the mobile phone positioning groove 401 is adapted to the mobile phone to be tested, reducing the testing error caused by the deviation of the mobile phone's placement angle, front-back and left-right positions during each test. The mobile phone positioning seat 4 is connected to the base plate 3 by bolts. When it is necessary to test mobile phones of different models and sizes, it is not necessary to replace the entire concentricity testing device. Only the bolts need to be removed and the corresponding specification of the mobile phone positioning seat 4 needs to be replaced.

[0044] Furthermore, the top of the mobile phone positioning base 4 is also provided with a mobile phone retrieval slot 402, and the mobile phone retrieval slot 402 is connected to the mobile phone positioning slot 401. The setting of the mobile phone retrieval slot 402 can provide operating space for fingers when taking out and putting in the mobile phone. After the mobile phone is placed in the mobile phone positioning slot 401, the edge of the phone body will be partially exposed in the mobile phone retrieval slot 402. The staff can insert their fingers into the mobile phone retrieval slot 402 and easily pinch the edge of the mobile phone to take it out, reducing the situation where the mobile phone is taken out due to the mobile phone being too tightly attached to the mobile phone positioning slot 401.

[0045] Furthermore, a computer bracket 501 is installed on the top of the support frame 301. The computer bracket 501 is connected to the top of the support frame 301 by bolts or welding. An industrial computer 5 is installed on the computer bracket 501. The industrial computer 5 is connected to the computer bracket 501 by bolts. An image acquisition card is connected between the industrial computer 5 and the camera 304. The industrial computer 5 receives the detection images captured by the camera 304 through the image acquisition card and can analyze the images in real time to realize the detection of the concentricity of the mobile phone camera. The detection principle is existing technology and will not be described in detail in this application.

[0046] The usage process of the light source angle adjustment mechanism and concentricity detection device provided by this utility model is as follows:

[0047] Loosen the first hand-tightening bolt 102, but not completely. It is advisable to allow the light source support arm 103 to rotate. Using the first hand-tightening bolt 102 as the center, rotate the light source support arm 103. After adjusting to a suitable initial angle, move the light source support arm 103 up and down to adjust the height of the light source structure 2. During the process, you can observe whether the light source illumination position roughly covers the detection area according to the subsequent testing requirements. After the height and angle are adjusted, tighten the first hand-tightening bolt 102. Pay attention to the fit between the bolt washer 104 and the light source support arm 103 to ensure that the light source support arm 103 is firmly fixed and does not wobble.

[0048] Loosen the second hand-tightening bolt 105, and rotate the light source structure 2 with the second hand-tightening bolt 105 as the center. Observe the light illumination angle of the supplementary light 205 through the transparent protective plate 203 until the light can be accurately focused on the area to be detected. After the angle is adjusted, tighten the second hand-tightening bolt 105 to complete the adjustment of the light source angle.

[0049] Observe the mobile phone positioning slot 401 and the mobile phone pick-up and drop slot 402 on the mobile phone positioning base 4. Place the mobile phone to be tested into the mobile phone positioning slot 401 through the mobile phone pick-up and drop slot 402, ensuring that the mobile phone is placed stably without offset or tilt. The mobile phone camera should be facing upwards and directly facing the camera 304. The camera 304 captures the image of the mobile phone camera and transmits the image to the industrial computer 5 through the image acquisition card for concentricity detection. After the detection is completed, take out the tested mobile phone from the mobile phone pick-up and drop slot 402 and put in the next mobile phone to be tested. Repeat the process to perform batch testing.
