Description

Technical Field

[0001] This utility model relates to the field of wet film thickness detection technology, specifically a paint wet film thickness detection device. Background Technology

[0002] Paint wet film is the liquid film layer that has not yet dried and cured after the paint is applied. Its thickness, uniformity and surface condition directly affect the final coating quality. The original design of the wet film comb is to quickly determine the coating thickness range by contacting the wet film with the comb teeth.

[0003] In existing technologies, when using a wet film comb, the operator first places the comb stably and vertically on a flat wet film surface. After removing it, the operator checks the highest tooth covered by the paint. The midpoint between two adjacent teeth is the wet film thickness. The scale range of each side of the hexagonal wet film comb is different, and the appropriate side needs to be selected according to the estimated thickness. However, in existing technologies, the operator uses a manual method to test the thickness of the wet film comb. When the operator needs to test the thickness of a large batch of paint wet films, the operator needs to frequently hold and operate the wet film comb. Furthermore, the operator's wrist may become sore after using the wet film comb for a long time, which may lead to inaccurate testing due to the operator's trembling wrist after a period of use. This greatly reduces the efficiency of continuous testing of paint wet films and causes inconvenience to the operator.

[0004] A paint wet film thickness detection device is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a paint wet film thickness detection device to solve the problems mentioned in the background art. Currently, the wet film thickness is determined by placing a wet film comb stably and vertically on a flat wet film surface, removing it, and then checking the highest tooth covered by the paint. The midpoint between two adjacent teeth is the wet film thickness. However, the scale range of each side of the hexagonal wet film comb is different, and the appropriate side needs to be selected according to the estimated thickness. In the prior art, the wet film comb is used manually by the operator. When the operator needs to detect the thickness of a large number of paint wet films, the operator needs to frequently hold the wet film comb. Furthermore, the operator's wrist may become sore after using the wet film comb for a long time, which may lead to wrist tremors and inaccurate detection after a period of use. This greatly reduces the efficiency of continuous paint wet film detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paint wet film thickness detection device, including a worktable, with support legs fixedly installed at the bottom of the worktable; an adjustment mechanism is provided at the top of the worktable, and positioning components are symmetrically arranged at the top of the worktable.

[0007] The adjustment mechanism includes a rotating column rotatably connected inside the workbench, with a mounting plate fixedly connected to the top of the rotating column. A first electric telescopic rod is fixedly connected to the top of the mounting plate, and a triangular plate is fixedly installed at the output end of the first electric telescopic rod. A support rod is fixedly connected to the top of the mounting plate, and the top of the support rod passes through the triangular plate and is slidably connected to it. A retraction spring is sleeved on the outside of the support rod, and a lifting rod is fixedly connected to the bottom of the triangular plate on the side away from the center. A clamping frame is fixedly connected to the bottom of the lifting rod.

[0008] Preferably, a gear is fixedly connected to the bottom of the rotating column, and a rotating rod is rotatably connected to one side of the bottom of the worktable. A gear is fixedly connected to the outside of the rotating rod, and the gear and the gear are meshed together. A forward and reverse motor is fixedly connected to the bottom of the rotating rod.

[0009] Preferably, a wet film comb is provided inside the clamping frame, and a second electric telescopic rod is fixedly connected to one side of the clamping frame. The output end of the second electric telescopic rod is fixedly connected to a first extrusion plate. A fixing rod is fixedly connected to one side of the clamping frame, and a second extrusion plate is fixedly connected to one end of the fixing rod. Rubber pads are fixedly connected to the corresponding sides of the first extrusion plate and the second extrusion plate.

[0010] Preferably, the positioning component includes L-plates, all of which are symmetrically and fixedly connected to the top of the worktable. A lifting plate is slidably connected to the inner side of the L-plate, and a screw is rotatably connected to the top of the lifting plate. The top of the screw passes through the L-plate and is threadedly connected to the L-plate. Limiting rods are symmetrically and fixedly connected to the top of the lifting plate, and the top of the limiting rods passes through the L-plate and is slidably connected to the L-plate. A stop block is fixedly connected to the top of the L-plate.

[0011] Preferably, a baffle is fixedly connected to the top of the support rod.

[0012] Preferably, a rubber plate is fixedly connected to the bottom of the lifting plate.

[0013] Preferably, the top of the forward and reverse motor is fixedly connected to the bottom of the worktable.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The device for detecting the wet film thickness of paint is described below: The operation of the first electric telescopic rod drives the triangular plate to move up and down. The movement of the triangular plate causes the three lifting rods to move down. At this time, the triangular plate slides between the support rods. Simultaneously, the spring contracts or extends. The downward movement of the lifting rods drives the movement of the clamping frame. The movement of the clamping frame causes the wet film comb to make perpendicular contact with the wet film surface. Finally, the operator removes the three wet film combs to detect the wet film thickness and clean the surface paint. This achieves the effect of quickly detecting the thickness of the wet film and can simultaneously detect multiple sets of wet film thicknesses, thus greatly improving the flexibility of equipment use. Compared to the manual operation of wet film combs in existing technologies, this method provides more accurate paint thickness data and effectively avoids inaccurate product testing caused by shaking of the wet film comb during the testing process. By having the operator rotate two sets of screws, the L-plate rotates internally. The rotation of the screws moves the lifting plate, which in turn moves the limiting rod inside the L-plate. At this time, the lifting plate moves the rubber plate downwards, squeezing and limiting the top two sides of the testing plate. This achieves a quick and effective fixation of the testing plate, effectively preventing the testing plate from shifting or shaking during wet film thickness testing. This significantly improves the accuracy of subsequent wet film testing and increases the efficiency of paint wet film thickness detection.

[0015] 1. The operation of the first electric telescopic rod drives the triangular plate to move up and down. The movement of the triangular plate causes the three lifting rods to move down. At this time, the triangular plate slides between the support rods. The contraction spring contracts or extends, and the downward movement of the lifting rods drives the clamping frame to move. The movement of the clamping frame causes the wet film comb to make vertical contact with the wet film surface. Then, the controller drives the output rod of the first electric telescopic rod to extend. At this time, the wet film comb moves away from the wet film. The operator can then remove the three wet film combs to check the wet film thickness and clean the surface paint. This allows for rapid thickness detection of the wet film and simultaneous detection of multiple sets of wet film thicknesses, greatly improving the flexibility of equipment use. Compared with the existing technology that uses manual operation of the wet film comb, the detected paint thickness data is more accurate and can effectively avoid inaccurate product detection caused by shaking of the wet film comb during the detection process. The operator operates the controller to drive the forward and reverse motors. The operation of the forward and reverse motors drives the rotation of the rotating rod, and the rotation of the rotating rod drives the gears. The rotation of the wheel and gear drives the rotation of the gear plate, which in turn drives the rotation of the rotating column. The rotation of the rotating column drives multiple sets of wet film combs to rotate, thus enabling rapid angle adjustment of the wet film combs. This facilitates the alignment of the wet film combs with the paint on the surface of the detection plate. The adjustable angle of the wet film combs also allows for easy disassembly and replacement, preventing workers from directly removing the combs from the top of the detection plate and coming into contact with the paint. This greatly improves the flexibility of the device. When the worker places the wet film comb inside the clamping frame, the rubber pads align with the center areas on both sides of the comb. Then, by operating the controller, the worker drives the second electric telescopic rod. The movement of the second electric telescopic rod moves the first extrusion plate towards the second extrusion plate. At this time, the two sets of rubber pads press and fix the wet film comb, thus achieving a rapid fixation and limiting effect on the wet film comb. This effectively prevents the wet film comb from shifting during subsequent wet film thickness detection, greatly improving the flexibility of the device.

[0016] 2. The worker places the paint-coated test plate between two sets of L-plates. Then, the worker rotates the two sets of screws, causing the L-plates to rotate internally. The rotation of the screws causes the lifting plate to move. The movement of the lifting plate causes the limiting rod to slide inside the L-plate. At this time, the lifting plate moves the rubber plate downward to squeeze and limit the top two sides of the test plate, thereby achieving a quick and effective fixation of the test plate. This effectively avoids the test plate from shifting or shaking when the wet film comb detects the thickness of the wet film, thus greatly improving the accuracy of subsequent wet film detection and increasing the efficiency of paint wet film thickness detection. The high friction of the rubber plate surface makes it difficult for the test plate to shift when fixed. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a paint wet film thickness detection device, including a workbench 1, with support legs 101 fixedly installed at the bottom of the workbench 1; an adjustment mechanism 2 is provided at the top of the workbench 1, and positioning components 3 are symmetrically arranged at the top of the workbench 1.

[0025] The adjusting mechanism 2 includes a rotating column 201 rotatably connected inside the workbench 1. A mounting plate 202 is fixedly connected to the top of the rotating column 201, and a first electric telescopic rod 203 is fixedly connected to the top of the mounting plate 202. A triangular plate 204 is fixedly mounted at the output end of the first electric telescopic rod 203. A support rod 205 is fixedly connected to the top of the mounting plate 202, and the top of the support rod 205 passes through the triangular plate 204 and is slidably connected to it. A retraction spring 206 is sleeved on the outside of the support rod 205. Furthermore, the bottom of the triangular plate 204 is fixedly connected to the lifting rod 207 on the side away from the center, and the bottom of the lifting rod 207 is fixedly connected to the clamping frame 208. This enables the rapid detection of wet film thickness and allows for the simultaneous detection of multiple sets of wet film thicknesses, thereby greatly improving the flexibility of equipment use. Compared with the existing technology that uses manual operation of the wet film comb 213, the detected paint thickness data is more accurate and can effectively avoid the inaccurate product detection caused by shaking or other factors during the detection process of the wet film comb 213.

[0026] A gear 209 is fixedly connected to the bottom of the rotating column 201, and a rotating rod 210 is rotatably connected to one side of the bottom of the worktable 1. A gear 211 is fixedly connected to the outside of the rotating rod 210, and the gear 209 and the gear 211 are meshed together. A forward and reverse motor 212 is fixedly connected to the bottom of the rotating rod 210, and the top of the forward and reverse motor 212 is fixedly connected to the bottom of the worktable 1. This enables the rapid adjustment of the angle of the wet film comb 213, making it convenient for workers to align the wet film comb 213 with the paint on the surface of the detection plate. The adjustable angle of the wet film comb 213 also makes it easy for workers to disassemble and replace it, avoiding the risk of workers directly removing the wet film comb 213 from the top of the detection plate and coming into contact with the paint. This greatly improves the flexibility of the device during use.

[0027] The clamping frame 208 is equipped with a wet film comb 213 inside, and a second electric telescopic rod 214 is fixedly connected to one side of the clamping frame 208. The output end of the second electric telescopic rod 214 is fixedly connected to a first extrusion plate 215. A fixing rod 216 is fixedly connected to one side of the clamping frame 208, and a second extrusion plate 217 is fixedly connected to one end of the fixing rod 216. Rubber pads 218 are fixedly connected to the corresponding sides of the first extrusion plate 215 and the second extrusion plate 217. This enables the wet film comb 213 to be quickly fixed and limited, thereby effectively preventing the wet film comb 213 from shifting during subsequent wet film thickness detection. This greatly improves the flexibility of the device during use. A baffle 219 is fixedly connected to the top of the support rod 205. The design of the baffle 219 enables the support rod 205 to be prevented from falling off.

[0028] The positioning component 3 includes an L-plate 301, which is symmetrically and fixedly connected to the top of the workbench 1. A lifting plate 302 is slidably connected to the inner side of the L-plate 301, and a screw 303 is rotatably connected to the top of the lifting plate 302. The top of the screw 303 passes through the L-plate 301 and is threadedly connected to the L-plate 301. A limit rod 304 is symmetrically and fixedly connected to the top of the lifting plate 302, and the top of the limit rod 304 passes through the L-plate 301 and is slidably connected to the L-plate 301. A stop block 305 is fixedly connected to the top of the L-plate 301, and a rubber plate 306 is fixedly connected to the bottom of the lifting plate 302. This enables the detection plate to be quickly fixed and limited, effectively preventing the detection plate from shifting or shaking when the wet film comb 213 detects the thickness of the wet film. This greatly improves the accuracy of subsequent wet film detection and increases the efficiency of paint wet film thickness detection. The high surface friction of the rubber plate 306 makes it less likely for the detection plate to shift when fixed.

[0029] Working principle: Before using this paint wet film thickness detection device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the staff places the equipment in a suitable area, then applies paint evenly to the test plate, and moves the test plate below the clamping frame 208. At this point, the staff places the adjusted wet film comb 213 inside the clamping frame 208 and fixes it. The staff operates the controller to drive the first electric telescopic rod 203, which in turn moves the triangular plate 204 up and down. The movement of the triangular plate 204 causes the three lifting rods 207 to move down. At this point, the triangular plate 204 slides between the support rods 205, causing the contraction spring 206 to contract or extend. The downward movement of the lifting rods 207 moves the clamping frame 208, which in turn moves the wet film comb 213. The membrane comb 213 is in vertical contact with the wet film surface. Then, the controller drives the first electric telescopic rod 203 to extend, moving the wet film comb 213 away from the wet film. The operator then removes the three wet film combs 213 to check the wet film thickness and clean the surface paint. This allows for rapid wet film thickness detection and simultaneous detection of multiple sets of wet film thicknesses, significantly improving the flexibility of the equipment. Compared to the existing manual operation of the wet film comb 213, the detected paint thickness data is more accurate, effectively avoiding inaccurate product detection caused by shaking of the wet film comb 213 during the detection process. The operator operates the controller to drive the forward and reverse motors 21... In operation, the forward and reverse motor 212 drives the rotating rod 210 to rotate, which in turn drives the gear 211 to rotate, which in turn drives the gear disc 209 to rotate, which in turn drives the rotating column 201 to rotate, which in turn drives multiple sets of wet film combs 213 to rotate. This allows for rapid angle adjustment of the wet film combs 213, facilitating alignment between the wet film combs 213 and the paint on the detection plate. The adjustable angle of the wet film combs 213 also allows for easy disassembly and replacement, preventing workers from directly removing them from the top of the detection plate and coming into contact with the paint. This significantly improves the flexibility of the device during use. The operator places the wet film comb 213 inside the clamping frame 208. At this time, the rubber pads 218 correspond to the center areas on both sides of the wet film comb 213. Then, the operator operates the controller to drive the second electric telescopic rod 214. The operation of the second electric telescopic rod 214 drives the first extrusion plate 215 to move towards the second extrusion plate 217. At this time, the two sets of rubber pads 218 squeeze and fix the wet film comb 213, thereby achieving the effect of quickly fixing and limiting the wet film comb 213. This effectively avoids the phenomenon of the wet film comb 213 shifting when detecting the wet film thickness, greatly improving the flexibility of the device during use. The design of the baffle 219 can achieve the effect of preventing the support rod 205 from falling off.

[0030] The worker places the paint-coated test plate between two sets of L-plates 301. Then, the worker rotates two sets of screws 303, causing the L-plates 301 to rotate internally. The rotation of the screws 303 causes the lifting plate 302 to move. The movement of the lifting plate 302 causes the limiting rod 304 to slide inside the L-plates 301. At this time, the lifting plate 302 moves the rubber plate 306 downward to squeeze and limit the top two sides of the test plate, thereby achieving the effect of quickly fixing and limiting the test plate. This effectively avoids the test plate from shifting or shaking when the wet film comb 213 detects the thickness of the wet film, thus greatly improving the accuracy of subsequent wet film detection and increasing the efficiency of paint wet film thickness detection. The high surface friction of the rubber plate 306 makes it difficult for the test plate to shift when fixed.
