Description

Technical Field

[0001] This application relates to the field of automated image analysis equipment, and particularly to a color difference analysis device. Background Art

[0002] Color difference analysis is a method for measuring and evaluating color differences. During the production process, due to various factors such as raw materials, processing techniques, and equipment status, the color of the product may differ from the standard color or sample color. To ensure product quality and customer satisfaction, it is necessary to analyze and control this color difference. Color difference analysis is widely used in fields such as textiles, coatings, plastics, and printing, and is an important part of product quality control.

[0003] In related technologies, when analyzing color differences of products, most devices do not have a corresponding positioning mechanism to effectively position the products. This makes the products prone to shaking during color difference analysis, which in turn affects the accuracy of the color difference analysis results of the device and is not conducive to the daily processing and production of products. Utility Model Content

[0007] The conveying mechanism is used to convey the product, and it consists of a front conveyor belt, a middle conveyor belt, and a rear conveyor belt. The front conveyor belt and the rear conveyor belt are distributed on the left and right sides of the control box, and the left and right sides of the middle conveyor belt are respectively connected to the front conveyor belt and the rear conveyor belt;

[0008] The lifting mechanism is installed at the bottom of the middle conveyor belt, and the lifting mechanism is used to drive the middle conveyor belt to lift in the vertical direction;

[0009] The stopping mechanism is connected to the lifting mechanism, and the stopping mechanism is used to stop the product;

[0010] The center positioning mechanism and the center tensioning mechanism are located between the middle conveyor belts, and the center tensioning mechanism and the center positioning mechanism are used to position the product.

[0011] By adopting the above technical solution, during specific operations, the product is conveyed by the front conveyor belt to the middle conveyor belt inside the control box. When the product reaches the specified position, the stop mechanism stops the product. At this time, the product is directly above the center positioning mechanism. Immediately afterwards, the lifting mechanism drives the middle conveyor belt and the stop mechanism to descend synchronously until the product is clamped onto the center positioning mechanism. After the color difference detection and analysis are completed, the lifting mechanism drives the middle conveyor belt and the stop mechanism to rise synchronously until the middle conveyor belt reaches the specified height. Immediately afterwards, the stop mechanism releases the stop on the product, and the product continues to be conveyed by the middle conveyor belt to the end conveyor belt, and finally is conveyed by the end conveyor belt to the next process for processing.

[0012] The center tensioning mechanism and the center positioning mechanism are used to stably position the product, so as to effectively prevent the product from shaking during the color difference analysis process, which is beneficial to ensuring the effect of the product color difference analysis.

[0013] Preferably, the lifting mechanism includes a first lifting cylinder, a lifting seat and a lifting plate. The first lifting cylinder is fastened to the bottom plate of the control box through fastening bolts. The piston rod of the first lifting cylinder is vertically upward and connected to the middle conveyor belt through a corresponding plate body. The first lifting cylinder is used to drive the middle conveyor belt to lift and lower.

[0014] The lifting seat is connected to the piston rod of the first lifting cylinder through a corresponding connecting plate. The lifting plate is installed on the lifting seat in the vertical direction, and the top of the lifting plate is connected to the middle conveyor belt.

[0015] The stop mechanism is installed on the lifting seat.

[0016] By adopting the above technical solution, while the first lifting cylinder drives the lifting seat to lift and lower, it synchronously drives the stop mechanism to lift and lower.

[0017] Preferably, the stop mechanism includes a sliding table, a sliding plate and a blocking wheel. The sliding table is horizontally arranged, and connecting plates are integrally formed on both the left and right sides of the sliding table. The connecting plates are connected to the first lifting cylinder, and the sliding table is connected to the first lifting cylinder through the connecting plates.

[0018] The sliding plate is slidably installed on the top of the sliding table in the horizontal direction, and the blocking wheel is installed on the top of the sliding plate.

[0019] By adopting the above technical solution, after the product is conveyed to the middle conveyor belt, the sliding plate is driven to move towards the product until the blocking wheel on the sliding plate stops the product. At this time, the product is directly above the center positioning mechanism. Then, the first lifting cylinder drives the middle conveyor belt to descend until the product is clamped onto the center positioning mechanism.

[0020] Preferably, a rubber ring is sleeved on the circumferential side of the blocking wheel.

[0021] By adopting the above technical solution, the rubber ring has a relatively soft texture. Using the rubber ring can effectively prevent the blocking wheel from directly contacting the product, which is beneficial to strengthening the safety guarantee of the product.

[0022] Preferably, the central positioning mechanism includes a positioning seat, a positioning table and a plurality of positioning components. The positioning seat is arranged between the middle conveyor belts. The positioning table is horizontally installed above the positioning seat. The plurality of positioning components are evenly distributed at intervals along the circumferential side of the positioning table.

[0023] The positioning component includes a positioning block, a mounting plate and a return spring. The positioning block is composed of a first block body and a second block body.

The return spring is inserted into the through hole, and both ends of the return spring extend out from the left and right ends of the second block body respectively. The mounting plate is fastened on the positioning table.

[0024] A chamber is formed between the plurality of positioning blocks. The central tensioning mechanism is inserted into the chamber. One end of the return spring abuts against the central tensioning mechanism, and the other end of the return spring is connected to the mounting plate.

[0025] By adopting the above technical solution, when the product is conveyed to the middle conveyor belt and stopped by the blocking wheel, the product is located directly above the positioning table. Then, driven by the first lifting cylinder, the middle conveyor belt descends until the positioning block completes the positioning of the product.

The piston rod of the tensioning cylinder is vertically upward towards the bottom of the positioning seat. The tensioning member is vertically connected to the piston rod of the tensioning cylinder, and the tensioning member vertically passes through the positioning seat and the positioning table and extends into the space between the plurality of positioning blocks. The tensioning member is in a conical shape.

[0027] By adopting the above technical solution, when the tensioning cylinder drives the tensioning member to extend upward into the space between the plurality of positioning blocks, the outer wall of the tensioning member compresses the return spring. The return spring drives the corresponding positioning block to slide towards the direction close to the mounting plate until these positioning blocks are respectively clamped to the rib walls of the product, thereby realizing the positioning of the product through these positioning blocks.

[0028] When the color difference analysis of the product is completed, the tensioning cylinder drives the tensioning member downward, and the return spring is reset. At this time, the return spring drives the corresponding positioning block to be reset to release the positioning of the product.

The baffle is installed on the fixed seat, the baffle is located between the two rollers of the front conveyor belt, the second lifting cylinder is installed at the bottom of the fixed seat, and the piston rod of the second lifting cylinder vertically passes through the fixed seat and is connected to the baffle.

[0032] By adopting the above technical solution, when the product to be detected is placed on the front conveyor belt, the second lifting cylinder drives the baffle to rise from between the two rollers, and the product is initially positioned by the blocking wheel on the baffle.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. During specific operations, the product is conveyed from the front conveyor belt to the middle conveyor belt in the control box. When the product reaches the designated position, the stop mechanism stops the product. At this time, the product is directly above the center positioning mechanism. Immediately afterwards, the lifting mechanism drives the middle conveyor belt and the stop mechanism to descend synchronously until the product is clamped onto the center positioning mechanism. After the color difference detection and analysis are completed, the lifting mechanism drives the middle conveyor belt and the stop mechanism to rise synchronously until the middle conveyor belt reaches the designated height. Immediately afterwards, the stop mechanism releases the stop on the product, and the product continues to be conveyed by the middle conveyor belt to the end conveyor belt, and finally is conveyed by the end conveyor belt to the next process for processing.

[0035] The center tensioning mechanism and the center positioning mechanism are used to stably position the product, so as to effectively prevent the product from shaking during the color difference analysis process, which is beneficial to ensuring the effect of the product color difference analysis;

[0036] 2. After the product is conveyed to the middle conveyor belt, the driving slide plate moves towards the product until the blocking wheel on the slide plate stops the product. At this time, the product is directly above the center positioning mechanism. Then, the first lifting cylinder is used to drive the middle conveyor belt to descend until the product is clamped onto the center positioning mechanism;

[0037] 3. When the tensioning cylinder drives the tensioning member to extend upward between the multiple positioning blocks, the outer wall of the tensioning member compresses the return spring, and the return spring drives the corresponding positioning blocks to slide toward the mounting plate until these positioning blocks are respectively clamped to the rib walls of the product, thereby realizing the positioning of the product through these positioning blocks.

[0048] Embodiment:

[0049] An embodiment of this application discloses a color difference analysis device. Referring to Figure 1 , Figure 2 and Figure 3 , it includes a conveying mechanism 1, a lifting mechanism 2, a stopping mechanism 3, a center positioning mechanism 4, a center tensioning mechanism 5, and a control box 6;

[0050] The conveying mechanism 1 is used to convey products. It consists of a front conveyor belt 11, a middle conveyor belt 12, and a rear conveyor belt 13. The middle conveyor belt 12 is installed inside the control box 6. The front conveyor belt 11 and the rear conveyor belt 13 are distributed on the left and right sides of the control box 6. The left and right sides of the middle conveyor belt 12 are respectively connected to the front conveyor belt 11 and the rear conveyor belt 13.

[0051] The lifting mechanism 2 is installed at the bottom of the middle conveyor belt 12. The lifting mechanism 2 is used to drive the middle conveyor belt 12 to lift in the vertical direction.

[0052] The stopping mechanism 3 is connected to the lifting mechanism 2. When the product is conveyed from the front conveyor belt 11 to the middle conveyor belt 12, the stopping mechanism 3 is used to stop the product.

[0053] The center positioning mechanism 4 and the center tensioning mechanism 5 are located between the middle conveyor belts 12. When the product is conveyed to the middle conveyor belt 12, the center tensioning mechanism 5 and the center positioning mechanism 4 are used to stably position the product, so as to effectively prevent the product from shaking during the color difference analysis process, which is conducive to ensuring the effect of the product color difference analysis.

[0054] At the same time, a corresponding robot is provided inside the control box 6. A manipulator is installed on the robot, and a color difference detector and a universal joint are installed on the manipulator. When the product is conveyed from the front conveyor belt 11 to the middle conveyor belt 12 and the positioning is completed, the color difference detector on the manipulator is used to detect and analyze the color difference of the product.

[0055] During specific operations, the product is conveyed by the front conveyor belt 11 to the middle conveyor belt 12 inside the control box 6. When the product reaches the specified position, the stopping mechanism 3 stops the product. At this time, the product is directly above the center positioning mechanism 4. Immediately afterwards, the lifting mechanism 2 drives the middle conveyor belt 12 and the stopping mechanism 3 to descend synchronously until the product is clamped onto the center positioning mechanism 4. After the color difference detection and analysis are completed, the lifting mechanism 2 drives the middle conveyor belt 12 and the stopping mechanism 3 to rise synchronously until the middle conveyor belt 12 reaches the specified height. Immediately afterwards, the stopping mechanism 3 releases the stop on the product, and the product continues to be conveyed by the middle conveyor belt 12 to the end conveyor belt 13, and finally is conveyed by the end conveyor belt 13 to the next process for processing.

[0056] Specifically, referring to Figure 1 and Figure 2 , the lifting mechanism 2 includes a first lifting cylinder 21, a lifting seat 22 and a lifting plate 23. The first lifting cylinder 21 is fastened to the bottom plate of the control box 6 by fastening bolts. The piston rod of the first lifting cylinder 21 is vertically upward and connected to the middle conveyor belt 12 through a corresponding plate body, and the first lifting cylinder 21 is used to drive the middle conveyor belt 12 to lift.

[0057] The lifting seat 22 is in the shape of a cuboid and is horizontally arranged. The lifting seat 22 is connected to the piston rod of the first lifting cylinder 21 through a corresponding connecting plate. The lifting plate 23 is installed on the lifting seat 22 in the vertical direction, and the top of the lifting plate 23 is connected to the middle conveyor belt 12.

[0058] The stopping mechanism 3 is installed on the lifting seat 22. When the first lifting cylinder 21 drives the lifting seat 22 to lift, it simultaneously drives the stopping mechanism 3 to lift.

[0059] In this embodiment, a total of four first lifting cylinders 21 are provided. The four first lifting cylinders 21 are spaced apart on the periphery of the middle conveyor belt 12. Using the four first lifting cylinders 21 is beneficial to ensuring the stability of the middle conveyor belt 12 during the lifting process.

[0060] Specifically, referring to Figure 2 , the stopping mechanism 3 includes a sliding table 31, a sliding plate 32 and a blocking wheel 33; the sliding table 31 is integrally in the shape of a cuboid and is horizontally arranged. Connecting plates are integrally formed on both the left and right sides of the sliding table 31, and the connecting plates are connected to the first lifting cylinder 21. The sliding table 31 is connected to the first lifting cylinder 21 through the connecting plates.

[0061] The skateboard 32 is slidably mounted horizontally on the top of the sliding table 31. The blocking wheels 33 are mounted on the top of the skateboard 32. There are two blocking wheels 33, and the two blocking wheels 33 are spaced apart and distributed at the left and right ends of the skateboard 32. A telescopic cylinder is mounted along the length direction at the bottom of the sliding table 31. The cylinder body of the telescopic cylinder is fastened to the sliding table 31 by fastening bolts, and the piston rod of the telescopic cylinder is connected to the skateboard 32 through a corresponding connecting plate. The telescopic cylinder is used to drive the skateboard 32 to slide on the sliding table 31.

[0062] After the product is conveyed to the middle conveyor belt 12, the skateboard 32 is driven to move towards the product until the blocking wheels 33 on the skateboard 32 block and stop the product. At this time, the product is directly above the center positioning mechanism 4. Then, the middle conveyor belt 12 is driven to descend by the first lifting cylinder 21 until the product is clamped to the center positioning mechanism 4.

[0063] Specifically, a screw rod is mounted vertically on the skateboard 32. A threaded hole is formed through the middle of the blocking wheel 33, and the screw rod is inserted into the threaded hole of the blocking wheel 33. The blocking wheel 33 is installed in a threaded manner by using the screw rod and the threaded hole, which facilitates the adjustment of the installation height of the blocking wheel 33. When it is necessary to block and stop the product, the blocking wheel 33 is turned outwards upwards; when it is necessary to release the blocking and stop of the product, the blocking wheel 33 is screwed downwards.

[0064] Further, referring to Figure 2 , a rubber ring 7 is sleeved on the circumferential side of the blocking wheel 33. The rubber ring 7 has a soft texture. The rubber ring 7 can effectively prevent the blocking wheel 33 from directly contacting the product, which is beneficial to strengthening the safety guarantee of the product.

[0065] Referring to Figure 3 and Figure 4 , the center positioning mechanism 4 includes a positioning seat 41, a positioning table 42 and multiple groups of positioning components 43. Referring to Figure 1 , Figure 2 and Figure 3 , the positioning seat 41 is fastened in the control box 6 through a corresponding support platform. The support platform is a square frame structure. The support platform is located between the middle conveyor belts 12, and the positioning seat 41 is mounted horizontally on the support platform. The positioning table 42 is mounted horizontally above the positioning seat 41 through a corresponding support seat, and multiple groups of positioning components 43 are evenly spaced and distributed along the circumferential side of the positioning table 42.

[0066] Referring to Figure 3 , Figure 4 and Figure 5, the positioning component 43 includes a positioning block 431, a mounting plate 432, and a return spring 433. The positioning block 431 is composed of a first block and a second block. The first block has an "L" - shaped structure and is integrally formed on the second block. The second block is horizontally arranged, and a through - hole is formed through the second block along its length direction. The return spring 433 is inserted into the through - hole, and both ends of the return spring 433 extend from the left and right ends of the second block respectively. The mounting plate 432 is fastened to the positioning table 42. A corresponding chamber is formed among multiple positioning blocks 431, and the center tensioning mechanism 5 is inserted into this chamber. One end of the return spring 433 abuts against the center tensioning mechanism 5, and the other end of the return spring 433 is connected to the mounting plate 432.

[0067] When the product is conveyed onto the middle conveyor belt 12 and stopped by the blocking wheel 33, the product is located directly above the positioning table 42. Immediately driven by the first lifting cylinder 21, the middle conveyor belt 12 descends until the positioning block 431 completes the positioning of the product.

[0068] Refer to Figure 3 , Figure 4 and Figure 5 , the center tensioning mechanism 5 includes a tensioning cylinder 51 and a tensioning member 52. The tensioning cylinder 51 is installed below the positioning seat 41, and the piston rod of the tensioning cylinder 51 is vertically upward towards the bottom of the positioning seat 41. The tensioning member 52 is connected to the piston rod of the tensioning cylinder 51 along the vertical direction, and the tensioning member 52 vertically upward passes through the positioning seat 41 and the positioning table 42 and extends into the space among multiple positioning blocks 431.

[0069] The tensioning member 52 is conical. When the tensioning cylinder 51 drives the tensioning member 52 to extend upward into the space among multiple positioning blocks 431, the outer wall of the tensioning member 52 compresses the return spring 433. The return spring 433 drives the corresponding positioning block 431 to slide towards the direction close to the mounting plate 432 until these positioning blocks 431 are respectively clamped to the rib walls of the product, and then the positioning of the product is realized through these positioning blocks 431.

[0070] When the color difference analysis of the product is completed, the tensioning cylinder 51 drives the tensioning member 52 downward, and the return spring 433 resets. At this time, the return spring 433 drives the corresponding positioning block 431 to reset to release the positioning of the product.

[0071] Further, refer to Figure 3 , Figure 4 and Figure 6 , a slide rail 8 is added to the positioning table 42. A slide seat 9 is integrally formed below the second block, and the slide seat 9 is slidably installed on the slide rail 8. The slide seat 9 and the slide rail 8 can play a guiding role for the positioning block 431 during the sliding process of the positioning block 431, which is beneficial to ensuring the stability of the positioning block 431 during the sliding process.

[0072] Further, referring to Figure 1 , Figure 2 and Figure 7 , an initial positioning mechanism 10 is further provided on the front-end conveyor belt 11. When a product on the middle-end conveyor belt 12 is subjected to color difference detection, the next product to be detected can be placed on the front-end conveyor belt 11 for waiting for inspection. At this time, the product is initially positioned by the initial positioning mechanism 10. After the product on the middle-end conveyor belt 12 is detected, the next product can be conveyed in time, which is beneficial to improving the efficiency of product detection.

[0073] Specifically, referring to Figure 1 , Figure 2 and Figure 7 , the initial positioning mechanism 10 includes a fixed seat 101, a second lifting cylinder 102 and a baffle 103. The fixed seat 101 is installed on the two inner walls of the front-end conveyor belt 11, and the installation height of the fixed seat 101 is lower than the installation height of the front-end conveyor belt 11. The baffle 103 is installed on the fixed seat 101. The baffle 103 is located between the two rollers of the front-end conveyor belt 11. Blocking wheels 33 are also installed at the left and right ends of the top of the baffle 103, and rubber rings 7 are also sleeved on the circumferences of the blocking wheels 33. The second lifting cylinder 102 is installed at the bottom of the fixed seat 101. The piston rod of the second lifting cylinder 102 vertically penetrates through the fixed seat 101 and is connected to the baffle 103.

[0074] When the product to be detected is placed on the front-end conveyor belt 11, the second lifting cylinder 102 drives the baffle 103 to rise from between the two rollers, and the product is initially positioned by the blocking wheels 33 on the baffle 103.

[0075] The implementation principle of a color difference analysis device according to an embodiment of the present application is as follows:

[0076] During specific operation, the product is conveyed by the front-end conveyor belt 11 to the middle-end conveyor belt 12 in the control box 6. When the product reaches the designated position, the stop mechanism 3 stops the product. At this time, the product is directly above the center positioning mechanism 4. Immediately afterwards, the lifting mechanism 2 drives the middle-end conveyor belt 12 and the stop mechanism 3 to descend synchronously until the product is clamped onto the center positioning mechanism 4. After the color difference detection and analysis are completed, the lifting mechanism 2 drives the middle-end conveyor belt 12 and the stop mechanism 3 to rise synchronously until the middle-end conveyor belt 12 reaches the designated height. Immediately afterwards, the stop mechanism 3 releases the stop on the product, and the product continues to be conveyed by the middle-end conveyor belt 12 to the end conveyor belt 13, and finally is conveyed by the end conveyor belt 13 to the next process for processing. The center tensioning mechanism 5 and the center positioning mechanism 4 are used to stably position the product to effectively prevent the product from shaking during the color difference analysis, which is beneficial to ensuring the effect of product color difference analysis.

[0077] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
