Description

Technical Field

[0001] The present invention relates to the technical field of flatness detection, in particular to a flatness detection electrical measurement platform. Background Art

[0002] In the electronics industry, some TP products, such as touch screens or touch panels, are widely used in smartphones, tablets, laptops, and industrial control equipment. After manufacturing, these TP products need to be tested for flatness to detect whether deformation during the production process has caused surface irregularities. This allows for later determination of whether the quality of the TP products meets production standards.

[0003] For example, the patent name disclosed in the prior art with the publication number "CN208921069U" is "A touch screen flatness detection device", which discloses that during use, two movable slides can be used to use vacuum to adsorb the workpiece, and then the hydraulic cylinder can be used to drive the push plate, so that the workpiece moves on the movable slide to the inside of the fixed frame, and then is detected by the detection module. Specifically, the first module slide rail, the second module slide rail and the third module slide rail can be used to move in conjunction with the laser detection component. At the same time, the detection sensor can perform real-time monitoring to improve the accuracy of the detection, and the functionality is strong. The patent name disclosed in the prior art with the publication number "CN203758471U" is "A nine-head laser flatness measuring instrument", which discloses that the laser is emitted The distance between the laser emitting unit and the test platform is pre-set to be equal to the working distance of the laser emitter, so that the distance between the laser emitting unit and the test platform is the working distance of the laser each time a test is performed. There is no need to lift the laser emitter each time a test is performed and adjust the distance between the sample test surface and the laser emitter after placing the sample as in the prior art. Instead, the test sample can be directly placed on the test platform for testing, which is very convenient to operate. Since nine laser emitters are provided, the parameters of nine positions of the test sample can be directly obtained in one test, which avoids the need to constantly adjust the position to obtain the parameters of different parts in the prior art. It has the characteristics of simple operation and accurate results. Therefore, the nine-head laser flatness measuring instrument has the characteristics of simple structure, easy operation and accurate test results.

[0004] Although the plane detection electrical measurement platform in the above-mentioned prior art is equipped with nine laser emitters, it can directly obtain the parameters of nine positions of the test sample in one test. However, after the test, the staff cannot promptly know which specific area of ​​the product is deformed and causes surface irregularities. Therefore, the area detected to have surface irregularities due to deformation cannot be marked or indicated, which makes it inconvenient for the staff to promptly level the area with surface irregularities due to deformation. Therefore, when the leveled product is tested again, the product may still be deformed, resulting in the flatness test failing again and requiring re-leveling. Repeated leveling and re-testing until the test is qualified will consume a lot of testing time, which will lead to a slow efficiency of the plane detection electrical measurement platform in detecting surface irregularities of the product. Therefore, we proposed a plane detection electrical measurement platform to solve the above-mentioned problems. Summary of the Invention

The right side of the control frame is threadedly connected to the second adjustment threaded rod installed above the right side of the detection base plate, and the control frame forms a lifting structure through the second adjustment threaded rod.

[0015] Preferably, a rack assembly corresponding one-to-one to the transmission gear is installed below the control frame, and the rack assembly is meshed and connected with the transmission gear.

[0017] Compared with the prior art, the present invention has the following beneficial effects: the plane detection electrical testing platform can easily indicate the detected surface irregularities caused by deformation, thereby facilitating the timely leveling of the surface irregularities caused by deformation by the subsequent staff, thereby improving the accuracy of the leveled areas and reducing the number of leveling and repeated testing times. Therefore, the efficiency of the plane detection electrical testing platform in detecting product surface irregularities can be improved, meeting different usage requirements. The specific contents are as follows:

[0018] By setting up nine groups of first laser ranging sensors, detection holes and indicator lights, the nine groups of first laser ranging sensors distributed in different positions can simultaneously detect the flatness of multiple areas of the product under test, which is convenient for detecting whether the product under test has surface irregularities due to deformation. At the same time, the numbers "1-9" are written in sequence with a marker on the detection top plate corresponding to the detection through hole and on the PLC controller corresponding to the indicator light. In this way, one second laser ranging sensor corresponds to one indicator light. When the indicator light of the corresponding number shows red, it indicates that the area of ​​the product under test corresponding to the detection through hole of the corresponding number has surface irregularities due to deformation. Therefore, it is convenient to indicate the detected surface irregular area, and then it is convenient for the subsequent staff to perform leveling operations on the surface irregular area in time, thereby improving the accuracy of the leveling area and reducing the number of leveling and repeated detections. Therefore, the efficiency of the plane detection electrical testing platform in detecting product surface irregularities can be improved to meet different usage needs.

[0019] The height adjustment mechanism can be used to slightly adjust the distance between the first laser ranging sensor and the product being measured, thereby avoiding signal loss, reflection interference or measurement blind spots caused by the distance being too close or too far, thereby avoiding affecting the accuracy of flatness detection. At the same time, different products being measured may have different heights or thicknesses. By adjusting the distance between the first laser ranging sensor and the product being measured, it can adapt to products of different sizes, thereby improving the versatility and efficiency of the flatness detection electrical measurement platform.

[0020] By using the second laser ranging sensor in conjunction with the digital display, the distance between the second laser ranging sensor and the first laser ranging sensor can be measured, thereby making it easier to know the moving position of the adjustment plate, thereby facilitating accurate control of the moving positions of multiple adjustment plates to accurately and minutely adjust the distance between the first laser ranging sensor and the measured product.

[0021] Through the meshing connection between the rack assembly and the transmission gear, the control frame can be controlled to drive multiple sets of rack assemblies to rise and fall synchronously by manually rotating the second adjusting threaded rod. Therefore, it is convenient to drive multiple sets of first adjusting threaded rods to rotate at the same time, and there is no need to manually rotate multiple first adjusting threaded rods one by one. This is not only convenient to operate, saves time and effort, but also further improves the efficiency of detecting surface irregularities. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The upper surface of the detection top plate 3 is symmetrically provided with isosceles trapezoidal grooves 302, which are convenient for manually placing and picking up the tested product 5 on the detection top plate 3. A through groove 201 is provided inside the detection pad 2, and a mounting bracket 11 is provided inside the through groove 201. The mounting bracket 11 is arranged in a one-to-one correspondence with the through groove 201. A detection through hole 301 is provided inside the detection top plate 3, and a first laser ranging sensor 10 is arranged in a one-to-one correspondence below the detection through hole 301. The number of the first laser ranging sensors 10 is the same as the number of the indicator lights 8. A limited position accommodating groove 101 is provided on the upper surface of the detection base plate 1, and the height adjustment mechanism includes a first adjusting threaded rod 9 that is rotatably installed in the limited position accommodating groove 101, and one end of the first adjusting threaded rod 9 is slidably connected to the adjustment member 10 in the limited position accommodating groove 101. The section plate 12 is threadedly connected, and a snap-in groove 121 is provided in the side of the adjustment plate 12 away from the first adjusting threaded rod 9. The first laser ranging sensor 10 is penetrated by the snap-in groove 121. The upper surface of the adjustment plate 12 away from the first adjusting threaded rod 9 is arranged in an inclined shape. The upper surface of the adjustment plate 12 away from the first adjusting threaded rod 9 is arranged in contact with the bottom surface of the mounting bracket 11. The mounting bracket 11 forms a lifting structure through the adjustment plate 12. The laser ranging assembly includes a second laser ranging sensor 123 installed in the middle inner part of the side of the adjustment plate 12 close to the first laser ranging sensor 10. The first laser ranging sensor 10 is correspondingly provided on the outer side of the second laser ranging sensor 123, and a digital display screen 122 is installed on the upper surface of the adjustment plate 12 close to the first adjusting threaded rod 9.

[0041] First, move the entire plane detection and electrical testing platform into the working area, and write the numbers "1-9" in sequence on the detection top plate 3 corresponding to the detection through hole 301 and on the PLC controller 7 corresponding to the indicator light 8 with a marker, so that a second laser ranging sensor 123 corresponds to an indicator light 8, connect the detection bottom plate 1 with the cable on the PLC controller 7, and connect the power line on the PLC controller 7 to the external power supply board. At this time, the staff manually places a product 5 to be tested on the detection top plate 3, and at the same time, through the setting of the groove 302, The staff puts their fingers in the groove 302, and then it is convenient to place and pick up the product 5 to be tested on the detection top plate 3. At this time, multiple positioning columns 4 can limit the outer side of the product 5 to prevent the product 5 to be tested from moving on the detection top plate 3. Then, the first laser ranging sensor 10 in the nine groups of detection through holes 301 below the product 5 can detect the flatness of multiple areas of the product 5. This detection part is an existing technology, so it will not be introduced in detail here. When the first laser ranging sensor 10 in the detection through hole 301 of the corresponding number detects When the flatness of the corresponding area of ​​the product 5 under test is qualified, the first laser ranging sensor 10 transmits an electrical signal to the PLC controller 7. After receiving the electrical signal, the PLC controller 7 controls the indicator light 8 of the corresponding number to light up green for indication. Similarly, when the first laser ranging sensor 10 in the detection through hole 301 of the corresponding number detects that the flatness of the corresponding area of ​​the product 5 under test is unqualified, the first laser ranging sensor 10 will not transmit an electrical signal to the PLC controller 7. The PLC controller 7 will not control the corresponding number if it does not receive the electrical signal. The indicator light 8 corresponding to the number lights up in red for indication. Therefore, by looking at the number corresponding to the indicator light 8 showing red, and then looking at the position of the detection through hole 301 corresponding to the corresponding number, you can know the specific position of the irregular area of ​​the tested product 5. Then the staff picks up the tested product 5, manually presses the corresponding position to level it, and then places the tested product 5 on the detection top plate 3 for testing until all nine indicator lights 8 light up in green, which means that the flatness of the tested position of the tested product 5 is qualified, and then the next tested product 5 is tested.

[0042] When the distance between the first laser ranging sensor 10 and the measured product 5 needs to be adjusted, the nine sets of first adjusting threaded rods 9 are manually rotated in sequence. When the first adjusting threaded rods 9 rotate, the adjusting plate 12 connected to the outer thread moves in the limit accommodating groove 101. Since the upper surface of the end of the adjusting plate 12 close to the mounting bracket 11 is inclined, the movement of the adjusting plate 12 will drive the mounting bracket 11 and the first laser ranging sensor 10 to rise or fall. At the same time, when the adjusting plate 12 moves, the second laser ranging sensor 123 inside will detect the distance with the first laser ranging sensor 10 in real time. The spacing between them can be controlled by controlling the moving position of the adjustment plate 12 to control the height of the first laser ranging sensor 10 to rise or fall. At this time, the spacing value detected by the second laser ranging sensor 123 is viewed through the digital display screen 122. When the detected spacing value reaches the required value, the rotation of the first adjustment threaded rod 9 is stopped. Therefore, the distance between the first laser ranging sensor 10 and the measured product 5 can be accurately and slightly adjusted, thereby avoiding affecting the accuracy of flatness detection, being able to adapt to measured products 5 of different sizes, and improving the versatility and efficiency of the plane detection electrical measurement platform.

[0043] At the same time, the detection base plate 1 is threadedly connected to the support column 6, so the placement height of the detection base plate 1 can be adjusted to meet different usage requirements.

[0044] Embodiment 2: The plane detection electric measuring platform in this embodiment, based on the embodiment 1, can simultaneously drive nine groups of first adjustment threaded rods 9 to rotate, without the need to manually rotate the nine groups of first adjustment threaded rods 9 one by one, which is not only convenient to operate, saves time and effort, but also further improves the efficiency of detecting irregularities on the product surface. For specific structure, please refer to the attached Figure 1 and attached Figures 9-11 As shown, the outer key of one end of the first adjusting threaded rod 9 away from the adjusting plate 12 is connected to the transmission gear 91, and a control frame 13 with a "U"-shaped structure is provided above the detection base plate 1, and vertical rods 15 are fixed at the four corners of the upper surface of the detection base plate 1, and the four corners of the control frame 13 are penetrated by the vertical rods 15. The right side of the control frame 13 is threadedly connected to the second adjusting threaded rod 14 installed on the upper right side of the detection base plate 1. The control frame 13 forms a lifting structure through the second adjusting threaded rod 14, and a rack assembly 131 corresponding to the transmission gear 91 is installed below the control frame 13, and the rack assembly 131 is meshed with the transmission gear 91.

[0045] In this embodiment, it is only necessary to install the digital display screen 122 and the second laser ranging sensor 123 in one of the adjustment plates 12, and the digital display screen 122 and the second laser ranging sensor 123 do not need to be installed in the other eight adjustment plates 12. When it is necessary to adjust the distance between the first laser ranging sensor 10 and the product 5 to be measured, it is only necessary to manually rotate the second adjustment threaded rod 14. When the second adjustment threaded rod 14 rotates, it drives the control frame 13 connected by the outer thread to move upward or downward. At this time, the vertical rod 15 is set to ensure that the control frame 13 stably drives the multiple rack assemblies 131 to move upward or downward, so that the rack assembly 131 drives the transmission gear 91 and the first adjustment threaded rod 9 to rotate clockwise or counterclockwise, and then drives multiple groups of first adjustment threaded rods 9 to rotate synchronously at the same time. Then, as shown in Example 1, the distance between the first laser ranging sensor 10 and the product 5 to be measured can be accurately and slightly adjusted, which can meet different usage requirements and complete a series of tasks.

[0046] Embodiment 3: The plane detection electrical measurement platform in this embodiment is based on the embodiment 1. When the entire plane detection electrical measurement platform is not in use, the detection through hole 301 can be covered to prevent external dust from contacting the first laser ranging sensor 10 through the detection through hole 301, thereby avoiding affecting the detection accuracy of the first laser ranging sensor 10. For the specific structure, please refer to the attached Figure 12-14 As shown, the internal groove of the detection top plate 3 is fitted and slidably connected with a cover plate 16, which divides the detection through hole 301 into two parts, an upper part and an lower part. The cover plate 16 is used to cover the detection through hole 301 in the lower part. The diameter of the upper part of the detection through hole 301 is smaller than the diameter of the lower part of the detection through hole 301. Nine groups of temporary storage grooves 161 and adjustment through holes 162 are opened inside the cover plate 16, and the temporary storage grooves 161 and the adjustment through holes 162 are arranged adjacent to each other. The diameter of the temporary storage grooves 161 is smaller than the diameter of the adjustment through holes 162, and the depth of the temporary grooves 161 is smaller than the depth of the adjustment through holes 162. The first magnet blocks 303 are installed in the two grooves 302 on the rear side, and the second magnet block 304 is installed in one of the grooves 302 on the front side. The opposing surfaces of the first magnet block 303 and the cover plate 16 and the opposing surfaces of the cover plate 16 and the second magnet block 304 are all opposite magnetic poles.

[0047] When the entire plane detection electrical measuring platform needs to be used, the cover plate 16 exposed in the groove 302 is manually pushed backward. At this time, the front side of the cover plate 16 is separated from the second magnet block 304, and then the rear side of the cover plate 16 is adsorbed and fixed to the first magnet block 303. At this time, the through hole 162 is adjusted to coincide with the detection through hole 301, and then as shown in Example 1, the first laser ranging sensor 10 can perform the detection work. When the entire plane detection electrical measuring platform is not in use, as shown above, the cover plate 16 is pushed forward. At this time, the front side of the cover plate 16 is adsorbed and fixed to the second magnet block 304, and then the rear side of the cover plate 16 is separated from the first magnet block 303. At this time, the through hole 162 is adjusted to coincide with the detection through hole 301. The hole 162 does not overlap with the detection through hole 301, and then the cover plate 16 can cover the detection through hole 301 in the lower part. At this time, the dust from the outside will fall into the temporary storage groove 161 through the interior of the detection through hole 301 in the upper part. The provision of the temporary storage groove 161 can collect and temporarily store the dust, and prevent the dust in the temporary storage groove 161 from falling into the detection through hole 301 when the cover plate 16 is moved backward, thereby further preventing the dust from falling onto the first laser ranging sensor 10 below through the detection through hole 301, thereby avoiding affecting the detection work and service life of the first laser ranging sensor 10. Later, the dust in the temporary storage groove 161 can be wiped and cleaned with wiping paper.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
