Description

Technical Field

[0001] The present invention relates to the technical field of flatness detection, and specifically to an electrical measurement platform for flatness detection. Background Art

[0002] In some TP products in the electronic product industry, such as touch screens or touch panels, etc., they are widely used in smart phones, tablet computers, laptop computers, and industrial control devices. After the production and manufacturing of these TP products are completed, it is necessary to detect their flatness to detect whether the TP products are deformed during the production process, resulting in an irregular surface, so as to judge whether the quality of the TP products meets the production standards in the later stage; For example, in the prior art, the patent with the publication number "CN208921069U" and the patent name "A Touch Screen Flatness Detection Device" discloses that during use, first, two moving sliders can be used to suck the workpiece by vacuum, and then the hydraulic cylinder is used to drive the push plate to move the workpiece into the fixed frame along with the moving slider. Then, it 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 in cooperation with the laser detection component for movement. At the same time, the detection sensor can perform real-time monitoring to improve the accuracy of detection, and it has strong functionality. Also, in the prior art, the patent with the publication number "CN203758471U" and the patent name "A Nine-Head Laser Flatness Measuring Instrument" discloses that the distance between the laser emission unit and the test platform is preset to be equal to the working distance of the laser emitter, so that the distance between the laser emission unit and the test platform during each test is the working distance of the laser. It is not necessary to lift the laser emitter and adjust the distance between the test surface of the sample 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, and the operation is very convenient. Since there are nine laser emitters, the parameters of nine positions of the test sample can be directly obtained in one test, avoiding the need to continuously adjust the position to obtain the parameters of different parts in the prior art, and having the characteristics of simple operation and accurate results. Therefore, the nine-head laser flatness measuring instrument has the characteristics of simple structure, convenient operation, and accurate test results.

[0003] In the planar detection electronic measurement platform in the above-mentioned prior art, although nine laser emitters are provided and parameters of nine positions of a test sample can be directly obtained in one test, after the detection, the staff cannot know in time which specific area of the product is deformed to cause surface irregularity. Therefore, the area detected to have surface irregularity due to deformation cannot be marked or indicated, and subsequently it is not convenient for the staff in the later stage to level the area with surface irregularity caused by deformation in time. Therefore, when the leveled product is detected again, the product may still be deformed, resulting in unqualified flatness detection again and requiring leveling again. Repeatedly leveling and then detecting until the detection is qualified will consume a large amount of detection time. Therefore, the detection efficiency of the planar detection electronic measurement platform for surface irregularity of the product is slow. So we propose a planar detection electronic measurement platform to solve the problems raised above. Summary of the Invention

[0004] The purpose of the present invention is to provide a planar detection electronic measurement platform to solve the problem in the above-mentioned background technology that the existing planar detection electronic measurement platforms on the market cannot mark or indicate the area detected to have surface irregularity due to deformation. Repeatedly leveling and then detecting until the detection is qualified will consume a large amount of detection time. Therefore, the detection efficiency of the planar detection electronic measurement platform for surface irregularity of the product is slow.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A planar detection electronic measurement platform includes a detection bottom plate, and a detection cushion plate installed on the upper surface of the detection bottom plate. The upper surface of the detection cushion plate is connected with a detection top plate. A measured product is placed on the upper surface of the detection top plate, and positioning columns for limiting the measured product are installed on the upper surface of the detection top plate. A first laser distance sensor is connected through the interior of the detection bottom plate, and the upper end of the first laser distance sensor is connected to an installation bracket installed in the detection cushion plate. A height adjustment mechanism for controlling the lifting of the installation bracket and the first laser distance sensor is installed inside the upper surface of the detection bottom plate. A PLC controller is connected to the rear side of the detection bottom plate. An indicator light is installed on the front side of the PLC controller. A laser distance measurement component for precise fine-tuning is installed inside the height adjustment mechanism.

[0006] Preferably, support columns are threadedly connected through the interior of the four corners of the lower surface of the detection bottom plate to stably support the detection bottom plate.

[0007] Preferably, isosceles trapezoid-shaped grooves are symmetrically formed on the upper surface of the detection top plate to facilitate manually placing and picking up the measured product on the detection top plate.

[0008] Preferably, a through groove is formed inside the detection cushion plate, and an installation bracket is arranged through the interior of the through groove. The installation brackets are arranged in one-to-one correspondence with the through grooves.

[0009] Preferably, a detection through-hole is formed inside the detection top plate, and a first laser distance sensor is correspondingly arranged below the detection through-hole. The number of the first laser distance sensors is the same as the number of the indicator lights.

[0010] Preferably, a limiting accommodation groove is formed on the upper surface of the detection bottom plate. The height adjustment mechanism includes a first adjustment screw rod rotatably installed through the limiting accommodation groove. One end of the first adjustment screw rod is threadedly connected to an adjustment plate slidably connected in the limiting accommodation groove. A clamping groove is formed inside one side surface of the adjustment plate away from the first adjustment screw rod. A first laser distance sensor is arranged through the clamping groove. The upper surface of one side of the adjustment plate away from the first adjustment screw rod is inclined. The upper surface of one side of the adjustment plate away from the first adjustment screw rod is in close contact with the bottom surface of the mounting bracket. The mounting bracket forms a lifting structure through the adjustment plate.

[0011] Preferably, the laser distance measurement assembly includes a second laser distance sensor installed inside the middle of one side of the adjustment plate close to the first laser distance sensor. A first laser distance sensor is correspondingly arranged outside the second laser distance sensor. A digital display screen is installed on the upper surface of one side of the adjustment plate close to the first adjustment screw rod.

[0012] Preferably, a transmission gear is key-connected to the outside of one end of the first adjustment screw rod away from the adjustment plate.

[0013] Preferably, a control frame in a "square frame" structure is arranged above the detection bottom plate. Vertical rods are fixed at the four corners of the upper surface of the detection bottom plate. The vertical rods penetrate through the four corners of the control frame. The right side inside the control frame is threadedly connected to a second adjustment screw rod installed above the right side of the detection bottom plate. The control frame forms a lifting structure through the second adjustment screw rod.

[0014] Preferably, a rack assembly corresponding to the transmission gear is installed below the control frame. The rack assembly is meshed with the transmission gear.

[0015] Preferably, a cover plate is in close sliding connection with the inner groove of the detection top plate. The cover plate divides the detection through-hole into upper and lower parts. The cover plate is used for covering the lower part of the detection through-hole. The diameter of the upper part of the detection through-hole is smaller than that of the lower part of the detection through-hole. Nine groups of temporary storage grooves and adjustment through-holes are formed inside the cover plate. The temporary storage grooves and the adjustment through-holes are arranged adjacent to each other. The diameter of the temporary storage groove is smaller than that of the adjustment through-hole. The depth of the temporary storage groove is smaller than that of the adjustment through-hole. First magnet blocks are installed inside the two grooves at the rear side. A second magnet block is installed inside one of the grooves at the front side. The opposite surfaces of the first magnet block and the cover plate and the opposite surfaces of the cover plate and the second magnet block are opposite magnetic poles.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The planar detection electrical measurement platform is convenient for indicating the areas with irregular surfaces caused by deformation detected, and then it is convenient for the later staff to level the areas with irregular surfaces caused by deformation in time, so as to improve the accuracy of the leveling area, reduce the number of leveling and repeated detections, and thus improve the efficiency of the planar detection electrical measurement platform for detecting the irregularities of the product surface, meeting different usage requirements. The specific content is as follows: By setting nine groups of first laser ranging sensors, detection through holes and indicator lights, the nine groups of first laser ranging sensors distributed at different positions can simultaneously detect the flatness of multiple areas of the product to be measured, facilitating the detection of whether there are irregularities on the surface of the product to be measured caused by deformation. At the same time, write the numbers "1-9" in sequence with a marker on the corresponding detection top plate next to the detection through hole and on the corresponding PLC controller next to the indicator light. In this way, one second laser ranging sensor corresponds to one indicator light. When the indicator light corresponding to the number shows red, it can indicate that there are irregularities on the surface of the product corresponding to the detection through hole corresponding to the number caused by deformation. Therefore, it is convenient to indicate the detected irregular surface areas, and then it is convenient for the later staff to level the irregular surface areas in time, so as to improve the accuracy of the leveling area, reduce the number of leveling and repeated detections, and thus improve the efficiency of the planar detection electrical measurement platform for detecting the irregularities of the product surface, meeting different usage requirements.

[0017] The height adjustment mechanism can slightly adjust the distance between the first laser ranging sensor and the product to be measured, avoiding signal loss, reflection interference or measurement blind spots caused by too close or too far distances, thus avoiding affecting the accuracy of flatness detection. At the same time, the heights or thicknesses of different products to be measured may be different. By adjusting the distance between the first laser ranging sensor and the product to be measured, it can adapt to products of different sizes, improving the versatility and efficiency of the planar detection electrical measurement platform.

[0018] By using the second laser ranging sensor in cooperation with the digital display screen, the distance between the second laser ranging sensor and the first laser ranging sensor can be measured, so as to facilitate knowing the moving position of the adjusting plate, and thus facilitate accurately controlling the moving positions of multiple adjusting plates to accurately and slightly adjust the distance between the first laser ranging sensor and the product to be measured.

[0019] Through the meshing connection of the rack assembly and the transmission gear, only by manually rotating the second adjusting screw rod, the control box can be driven to drive multiple rack assemblies to lift synchronously. Therefore, it is convenient to drive multiple first adjusting screw rods to rotate simultaneously without manually rotating each of the multiple first adjusting screw rods one by one. It is not only convenient to operate, time-saving and labor-saving, but also further improves the detection efficiency of surface irregularities. Description of the Drawings

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 14 , the present invention provides the following technical solutions: Embodiment 1: The planar detection electronic measurement platform in this embodiment can not only detect whether the surface of the product 5 to be measured is irregular due to deformation, but also indicate the specific irregular area, which is convenient for the later staff to quickly level the specific irregular area, thereby reducing the number of leveling and repeated detections. Therefore, the efficiency of the planar detection electronic measurement platform for detecting the irregularities on the product surface can be improved. The specific structure is shown in the attached Figures 1 - 8 figure, and it includes a detection bottom plate 1, and a detection cushion plate 2 installed on the upper surface of the detection bottom plate 1. The upper surface of the detection cushion plate 2 is connected to a detection top plate 3. The upper surface of the detection top plate 3 is provided with the product 5 to be measured, and a positioning column 4 for limiting the product 5 to be measured is installed on the upper surface of the detection top plate 3. A first laser distance sensor 10 is connected through the inside of the detection bottom plate 1, and the upper end of the first laser distance sensor 10 is connected to a mounting bracket 11 installed in the detection cushion plate 2. A height adjustment mechanism for controlling the lifting of the mounting bracket 11 and the first laser distance sensor 10 is installed inside the upper surface of the detection bottom plate 1. The rear side of the detection bottom plate 1 is connected to a PLC controller 7, and an indicator light 8 is installed on the front side of the PLC controller 7. A laser distance measurement component for precise fine-tuning is installed inside the height adjustment mechanism. Threaded support columns 6 are connected through the four corners inside the lower surface of the detection bottom plate 1 to stably support the detection bottom plate 1.

[0024] 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 product 5 to be measured on the detection top plate 3. A through groove 201 is provided inside the detection backing plate 2, and an installation bracket 11 is arranged through the inside of the through groove 201. The installation brackets 11 are arranged in one-to-one correspondence with the through grooves 201. Detection through holes 301 are provided inside the detection top plate 3, and first laser distance sensors 10 are provided below the detection through holes 301 in one-to-one correspondence. The number of the first laser distance sensors 10 is the same as the number of the indicator lights 8. A limit accommodation groove 101 is provided on the upper surface of the detection bottom plate 1. The height adjustment mechanism includes a first adjustment screw rod 9 that is rotatably installed through the limit accommodation groove 101. One end of the first adjustment screw rod 9 is threadedly connected to an adjustment plate 12 that is slidably connected in the limit accommodation groove 101. A clamping groove 121 is provided inside one side surface of the adjustment plate 12 away from the first adjustment screw rod 9, and the first laser distance sensor 10 is arranged through the inside of the clamping groove 121. The upper surface of one side of the adjustment plate 12 away from the first adjustment screw rod 9 is arranged in an inclined shape, and the upper surface of one side of the adjustment plate 12 away from the first adjustment screw rod 9 is in close contact with the bottom surface of the installation bracket 11. The installation bracket 11 forms a lifting structure through the adjustment plate 12. The laser distance measurement assembly includes a second laser distance sensor 123 installed inside the middle of one side of the adjustment plate 12 close to the first laser distance sensor 10. The first laser distance sensors 10 are correspondingly arranged on the outer side of the second laser distance sensor 123. A digital display screen 122 is installed on the upper surface of one side of the adjustment plate 12 close to the first adjustment screw rod 9.

[0025] First, move the entire planar detection electrical measurement platform into the working area. Use a marker pen to write the numbers "1-9" on the corresponding detection top plate 3 next to the detection through hole 301 and on the corresponding PLC controller 7 next to the indicator light 8 in sequence. In this way, one second laser distance sensor 123 corresponds to one indicator light 8. Connect the cable on the detection bottom plate 1 to the PLC controller 7, and connect the power cord on the PLC controller 7 to the external power supply socket. At this time, the staff manually places a product under test 5 on the detection top plate 3. At the same time, due to the setting of the groove 302, it is convenient for the staff to place their fingers in the groove 302, and then it is convenient to place and pick up the product under test 5 on the detection top plate 3. At this time, multiple positioning posts 4 can limit the outside of the product under test 5 to prevent the product under test 5 from moving on the detection top plate 3. Then, the first laser distance sensors 10 in the nine groups of detection through holes 301 below the product under test 5 can detect the flatness of multiple areas of the product under test 5. This detection part is prior art, so it will not be introduced in detail here. When the first laser distance sensor 10 in the detection through hole 301 corresponding to the number detects that the flatness of the corresponding area of the product under test 5 directly above is qualified, at this time, the first laser distance sensor 10 transmits an electrical signal to the PLC controller 7. After receiving the electrical signal, the PLC controller 7 will control the indicator light 8 corresponding to the number to light up and display green for indication. Similarly, when the first laser distance sensor 10 in the detection through hole 301 corresponding to the number detects that the flatness of the corresponding area of the product under test 5 directly above is unqualified, at this time, the first laser distance sensor 10 will not transmit an electrical signal to the PLC controller 7. If the PLC controller 7 does not receive the electrical signal, it will control the indicator light 8 corresponding to the number to light up and display red for indication. Therefore, by looking at the number corresponding to the indicator light 8 that shows red and then looking at the position of the detection through hole 301 corresponding to this corresponding number, it is possible to know the specific position of the irregular area of the product under test 5. Then, the staff picks up the product under test 5 and manually presses and flattens the corresponding position. After flattening, place the product under test 5 on the detection top plate 3 for detection until all nine indicator lights 8 light up and display green, which means that the flatness of the detected position of the product under test 5 is qualified. Then, proceed to detect the next product under test 5.

[0026] When it is necessary to adjust the distance between the first laser distance sensor 10 and the product 5 to be measured, the nine groups of first adjusting threaded rods 9 are manually rotated in sequence at this time. When the first adjusting threaded rod 9 rotates, it drives the adjusting plate 12 connected by external threads to move 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 adjusting plate 12 drives the mounting bracket 11 and the first laser distance sensor 10 to rise or fall when moving. At the same time, the second laser distance sensor 123 inside the adjusting plate 12 will detect the distance from the first laser distance sensor 10 in real time. By controlling the moving position of the adjusting plate 12, the height of the first laser distance sensor 10 rising or falling can be controlled. At this time, the digital display screen 122 is used to view the distance value detected by the second laser distance sensor 123. When the detected distance value reaches the required value, the rotation of the first adjusting threaded rod 9 is stopped at this time. Therefore, the distance between the first laser distance sensor 10 and the product 5 to be measured can be accurately and slightly adjusted, thus avoiding affecting the accuracy of flatness detection, adapting to products 5 of different sizes, and improving the versatility and efficiency of the flat detection electrical measurement platform.

[0027] The detection bottom plate 1 is threadedly connected to the support column 6, so the placement height position of the detection bottom plate 1 can be adjusted to meet different use requirements.

[0028] Embodiment 2: The flat detection electrical measurement platform in this embodiment can drive the nine groups of first adjusting threaded rods 9 to rotate simultaneously on the basis of Embodiment 1, without manually rotating the nine groups of first adjusting threaded rods 9 one by one. It is not only convenient and time-saving, but also further improves the efficiency of detecting the irregularities on the product surface. The specific structure is as shown in the attached Figure 1 and the attached Figures 9 - 11 As shown, a transmission gear 91 is key-connected to the outer side of the end of the first adjusting threaded rod 9 away from the adjusting plate 12. Above the detection bottom plate 1, a control frame 13 with a "hui" - shaped structure is provided. Vertical rods 15 are fixed at the four corners of the upper surface of the detection bottom plate 1, and the vertical rods 15 penetrate through the four corners inside the control frame 13. The second adjusting threaded rod 14 installed above the right side of the detection bottom plate 1 penetrates and is threadedly connected to the inside of the right side of the control frame 13. The control frame 13 forms a lifting structure through the second adjusting threaded rod 14. Below the control frame 13, a rack assembly 131 corresponding to the transmission gear 91 one by one is installed, and the rack assembly 131 is meshed with the transmission gear 91.

[0029] In this embodiment, only a digital display screen 122 and a second laser distance measuring sensor 123 need to be installed in one of the adjusting plates 12, and there is no need to install a digital display screen 122 and a second laser distance measuring sensor 123 in the other eight adjusting plates 12. When it is necessary to adjust the distance between the first laser distance measuring sensor 10 and the product 5 to be measured, only the second adjusting screw rod 14 needs to be manually rotated at this time. When the second adjusting screw rod 14 rotates, it drives the control box 13 connected by external threads to move upward or downward. At this time, through the setting of the vertical rod 15, it is ensured that the control box 13 stably drives a plurality of rack assemblies 131 to move upward or downward. Therefore, the rack assembly 131 drives the transmission gear 91 and the first adjusting screw rod 9 to rotate clockwise or counterclockwise, and then a plurality of groups of first adjusting screw rods 9 can be driven to rotate synchronously. Then, as shown in Embodiment 1, the distance between the first laser distance measuring sensor 10 and the product 5 to be measured can be accurately and microscopically adjusted, which can meet different usage requirements, and thus a series of work can be completed.

[0030] Embodiment 3: For the planar detection and electrical measurement platform in this embodiment, on the basis of Embodiment 1, when the entire planar detection and electrical measurement platform is not in use, the detection through-hole 301 can be covered to prevent external dust from contacting the first laser distance measuring sensor 10 through the detection through-hole 301, thereby avoiding affecting the detection accuracy of the first laser distance measuring sensor 10. The specific structure is as shown in the attached Figures 12 - 14 figure. A cover plate 16 is slidably connected to the inner groove of the detection top plate 3. The cover plate 16 divides the detection through-hole 301 into upper and lower parts. The cover plate 16 is used to cover the lower part of the detection through-hole 301. The diameter of the upper part of the detection through-hole 301 is smaller than that of the lower part of the detection through-hole 301. Nine temporary storage grooves 161 and adjustment through-holes 162 are formed in the cover plate 16, and the temporary storage grooves 161 and the adjustment through-holes 162 are adjacent to each other. The diameter of the temporary storage groove 161 is smaller than that of the adjustment through-hole 162, and the depth of the temporary storage groove 161 is smaller than that of the adjustment through-hole 162. First magnet blocks 303 are installed in the two grooves 302 at the rear side, and a second magnet block 304 is installed in one of the grooves 302 at the front side. The opposite surfaces of the first magnet block 303 and the cover plate 16 and the opposite surfaces of the cover plate 16 and the second magnet block 304 are opposite magnetic poles.

[0031] When the entire planar detection and electrical measurement platform needs to be used, manually push the cover plate 16 exposed in the groove 302 backward at this time. At this time, the front side surface of the cover plate 16 is separated from the second magnet block 304, and then the rear side surface of the cover plate 16 is adsorbed and fixed to the first magnet block 303. At this time, adjust the through hole 162 to coincide with the detection through hole 301, and then as shown in Embodiment 1, the first laser ranging sensor 10 can perform the detection work. When the entire planar detection and electrical measurement platform is not in use, similarly as described above, push the cover plate 16 forward. At this time, the front side surface of the cover plate 16 is adsorbed and fixed to the second magnet block 304, and then the rear side surface of the cover plate 16 is separated from the first magnet block 303. At this time, adjust the through hole 162 not to coincide with the detection through hole 301, and then the cover plate 16 can cover the lower part of the detection through hole 301. At this time, external dust will fall into the temporary storage groove 161 through the inside of the upper part of the detection through hole 301. Through the setting of the temporary storage groove 161, the dust can be collected and temporarily stored, avoiding 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 avoiding the dust from falling onto the first laser ranging sensor 10 below through the detection through hole 301, and avoiding affecting the detection work and service life of the first laser ranging sensor 10. Later, a wiping paper can be taken to wipe and clean the dust in the temporary storage groove 161.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
