Description

Technical Field

[0001] This utility model relates to the field of color mixing technology, and more specifically to a desktop color mixing instrument for shoe sole production. Background Technology

[0002] Color matching instruments are categorized by size into portable and benchtop color matching instruments. Portable color matching instruments are smaller and easier to carry, but their measurement accuracy is limited due to size constraints. Benchtop color matching instruments, on the other hand, offer high-precision color measurement and matching capabilities. Compared to portable instruments, they are larger, offer higher measurement accuracy, and are more stable. Therefore, benchtop color matching instruments are commonly used in scenarios where mobility is not required and high accuracy is demanded, such as when inspecting specific products in a production workshop.

[0003] To ensure measurement accuracy, desktop colorimeters require the probe to be in close contact with the object being measured during measurement to prevent light leakage. For example, Chinese utility model patent CN219935115U discloses a desktop colorimeter where, under normal conditions, the slide plate 6 covers the detection chamber 3, and the upper part of the longitudinal slider 11 moves into the detection chamber 3. First, the slide plate 6 is pushed upwards, causing the positioning slider 7 to adhere to the top of the longitudinal groove 101. Then, the water bottle 5 is placed into the detection chamber 3. When it touches the longitudinal slider 11, the adjusting block 9 is pulled outwards, causing the transverse slider 8 to separate from the longitudinal slider 11. At this point, the longitudinal slider 11 falls back into the placement groove 103. Then, the water bottle 5 is placed into the detection chamber 3. When the other end of the detection cavity 3 is pushed, and it is located below the probe 4 and above the longitudinal slider 11, the adjusting block 9 is released. During the reset process, the tension spring 10 causes the transverse slider 8 to move towards the inside of the adjusting groove 102 and pushes the longitudinal slider 11 out of the placement groove 103 to move into the detection cavity 3 and abut against the lower surface of the kettle 5. Then, the sliding plate 6 is moved to cover the detection cavity 3 again. Finally, the touch screen 2 is used for touch operation, and the probe 4 is used to detect the color difference of the kettle 5 in the detection cavity 3. This reduces the difficulty of electric kettle detection and improves the accuracy of electric kettle detection.

[0004] In the aforementioned patent, the elasticity of the tension spring 10 cannot be adjusted. If the elasticity of the tension spring 10 is too large, it will cause the water bottle 5 and the probe 4 to be too close together, damaging the side head 4. After repeated use, the tension spring 10 will deform and lose its original elasticity, which will reduce the contact force between the longitudinal slider 11 and the lower surface of the water bottle 5, making it impossible for the probe 4 and the water bottle 5 to fit tightly together. Therefore, it is necessary to upgrade the structure and study a desktop color mixing instrument suitable for shoe soles. Utility Model Content

[0005] The purpose of this utility model is to provide a desktop color mixing instrument for shoe sole production in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A desktop color mixing instrument for shoe sole production includes a color mixing instrument body and a testing box on the color mixing instrument body;

[0008] The side wall of the test box is equipped with a sliding device, which includes a slide block, a screw, and a slider. The slider is threadedly connected to the screw, and both ends of the screw are rotatably connected to the slide block. A limit rod is provided on the slide block, and the lower end of the limit rod passes through the slider.

[0009] The slide is connected to the probe via the connecting wall;

[0010] A servo motor is installed on the top of the testing box, and the output shaft of the servo motor is connected to one end of the screw.

[0011] By using a servo motor to drive the screw to rotate, the slider slides up and down along the limit rod, thereby causing the probe to come into contact with or separate from the object being measured. In this invention, the servo motor is controlled by a servo driver, which can provide high-precision and stable power output. This helps to improve the accuracy of the motor speed and position, ensuring stable contact between the probe and the object being measured, and improving the accuracy of the detection.

[0012] The desktop color adjuster also includes a clamp, which includes a grooved plate and a pressure plate. The grooved plate is provided with two parallel sliding sleeves, and a sliding rod is inserted into the sliding sleeve. A first spring is sleeved on the sliding rod. The lower end of the sliding rod is fixedly connected to the pressure plate, and the upper end of the sliding rod passes through the sliding sleeve and is fixedly connected to the handle. Existing clamps are designed at the bottom of the testing box, and their structure is complex. Generally, the sole surface is placed and fixed upwards. However, the sole surface has many heat dissipation holes, which will affect the detection if they are directly facing the testing head. Existing clamps cannot adjust the position of the sole, thus greatly reducing the accuracy of the detection. The sidewall of the sole generally does not have heat dissipation holes. If the detection could be performed from the sidewall of the sole, the accuracy of the detection would be increased. However, there are currently no clamps on the market that can make the sidewall of the sole stand upright. Therefore, it is necessary to research a clamp with a simple structure that can also adjust the position of the sole. The clamp of this utility model can achieve the above functions. In use, the pressure plate is pulled open and the sole is clamped to make the sidewall of the sole stand upright. The sidewall of the sole is placed under the probe. When the sole surface needs to be detected, the position of the sole is readjusted and then placed into the clamp and clamped. The clamp of this utility model can clamp different parts of the sole for multi-angle detection, and can also move the sole to avoid the heat dissipation holes to improve the detection accuracy.

[0013] The testing chamber is equipped with a door. The object to be tested is placed into the testing chamber through the door, and when the door is closed, the testing chamber is sealed to prevent light leakage from affecting the testing.

[0014] The desktop colorimeter also includes a desktop computer with a built-in formula database. The probe communicates with the desktop computer. The desktop computer's display screen is embedded in the colorimeter body for easy viewing by the operator, and the computer's main unit is located inside the colorimeter body. The probe transmits the detected data to the desktop computer, which then searches for the corresponding formula in the formula database based on the detection data (this is prior art and will not be described in detail here). Finally, the formula is displayed on the screen.

[0015] The desktop colorimeter also includes a protective device, which comprises a protective platform, a vertical rod, and a pressure sensor. The top of the protective platform is fixedly connected to the top of the detection box, and the top of the vertical rod is fixedly connected to the protective platform. A pressure sensor is located at the bottom of the protective platform, below the vertical rod. An upper pressure sleeve, a second spring, and a lower pressure sleeve are sequentially fitted onto the vertical rod from top to bottom. The second spring is fixedly connected to the upper pressure sleeve, and the lower pressure sleeve contacts the pressure sensor. The upper pressure sleeve is connected to the probe via an L-shaped plate. This protective device protects the probe from side damage, ensuring its vertical movement. It also prevents excessive pressure on the probe, thus avoiding damage. The pressure sensor is electrically connected to the desktop computer. The sensor transmits the measured pressure value to the computer. When the pressure exceeds a preset threshold, the computer sends a command to the servo motor, causing it to stop.

[0016] There is a 5mm gap between the pressure sensor and the vertical rod.

[0017] The desktop colorimeter also includes a detection area qualification detection device, which consists of two laser rangefinders symmetrically mounted on both sides of the probe. The area projected onto the object to be measured by the probe is the detection area. Accuracy can only be guaranteed if the detection area is parallel or nearly parallel to the probe. Using two laser rangefinders solves this technical problem. Specifically, as long as the difference between the distances measured by the two laser rangefinders is within the error range, the detection area is considered qualified.

[0018] The probe has a silicone ring at its bottom. The silicone ring is used to protect the bottom of the probe and prevent damage. In addition, the silicone ring has good elasticity, which allows it to form a tight fit with the object being measured, something that ordinary probes cannot do.

[0019] A moving distance sensor is installed on the top of the protective platform, and the moving distance sensor is located above the probe.

[0020] The operating procedure for a benchtop color mixing instrument used in shoe sole production includes the following steps:

[0021] S1, Place the sole of the shoe into the clamp to fix it in place;

[0022] S2, place the sole of the shoe under the toe;

[0023] S3, the inspection area qualification inspection device inspects the sole of the shoe and determines whether the inspection area is qualified. If the inspection area is not qualified, the sole of the shoe is adjusted so that the inspection area is parallel to the probe, and then the inspection continues until the inspection area is qualified.

[0024] The detection area must meet the following conditions to be considered qualified: the distances measured by the two laser rangefinders are D1 and D2, the difference between D1 and D2 is < ΔD, and ΔD = 2mm;

[0025] S4, calculate the probe's movement distance L, which satisfies the following condition: L=(D1+D2+d) / 2, where d is the thickness of the silicone ring, d=5mm;

[0026] S5, the servo motor controls the probe to move downwards. The moving distance sensor monitors the distance Q between the moving distance sensor and the probe. When Q = L + R, the probe stops moving downwards, where R is the distance from the initial position of the probe to the moving distance sensor. R is a constant, and the initial position of the probe is the position where the probe stopped before each downward movement.

[0027] S6, the probe detects the sole of the shoe and transmits the detection data to the desktop computer.

[0028] The beneficial effects of this utility model are as follows:

[0029] The servo motor provides high-precision and stable power output, ensuring stable contact between the probe and the object being tested, thus improving detection accuracy. The fixture can clamp different parts of the shoe sole for multi-angle detection, and can also move the shoe sole to avoid heat dissipation holes, further improving detection accuracy.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1 to 5 As shown, this embodiment provides a desktop color mixing instrument for shoe sole production, including a color mixing instrument body 1, and a detection box 2 is provided on the color mixing instrument body 1;

[0040] The side wall of the test box 2 is provided with a sliding device, which includes a slide block 3, a screw 4 and a slider 5. The slider 5 is threadedly connected to the screw 4. Both ends of the screw 4 are rotatably connected to the slide block 3. The slide block 3 is provided with a limiting rod 6, and the lower end of the limiting rod 6 passes through the slider 5.

[0041] The slide 3 is connected to the probe 18 via the connecting wall 7;

[0042] The top of the testing box 2 is equipped with a servo motor 8, and the output shaft of the servo motor 8 is connected to one end of the screw 4.

[0043] By setting a servo motor 8 to drive the screw 4 to rotate, the slider 5 slides up and down along the limiting rod 6, thereby causing the probe 18 to adhere to or separate from the object to be measured. In this invention, the servo motor 8 is controlled by a servo driver, which can provide high-precision and stable power output. This helps to improve the accuracy of the motor speed and position, making the probe 18 and the object to be measured fit stably and improving the accuracy of the detection.

[0044] The desktop colorimeter also includes a clamp 9, which comprises a grooved plate 10 and a pressure plate 11. Two parallel sliding sleeves 12 are provided on the grooved plate 10, and a sliding rod 13 is inserted into each sleeve. A first spring 14 is fitted onto the sliding rod 13. The lower end of the sliding rod 13 is fixedly connected to the pressure plate 11, and the upper end of the sliding rod 13 extends through the sleeve 12 and is fixedly connected to a handle 15. Currently, the clamp 9 is designed at the bottom of the detection box 2. The clamp 9 has a complex structure and is generally placed with the sole 16 facing upwards. However, the sole 16 has many ventilation holes, and if it is directly facing the detection head 18, it will affect the detection. The existing clamp 9 cannot adjust the position of the sole 16, thus greatly reducing the accuracy of the detection. Ventilation holes are generally not provided on the sidewalls of the sole 16. If the detection could be performed from the sidewalls of the sole 16, the accuracy of the detection would be increased. However, there are currently no clamps 9 on the market that allow the sidewalls of the sole 16 to stand upright; therefore, it is necessary to address this issue. This invention relates to a simple clamp 9 that can adjust the position of the sole 16. The clamp 9 of this invention can achieve the above functions. In use, the pressure plate 11 is pulled open and the sole 16 is clamped so that the side wall of the sole 16 stands up. The side wall of the sole 16 is placed under the probe 18. When it is necessary to test the surface of the sole 16, the position of the sole 16 is readjusted and then placed into the clamp 9 and clamped. The clamp 9 of this invention can clamp different parts of the sole 16 for multi-angle testing, and can also move the sole 16 to avoid the heat dissipation holes to improve the testing accuracy.

[0045] The testing chamber 2 is equipped with a door cover 17. The object to be tested is placed into the testing chamber 2 by setting the door cover 17. When the door cover 17 is closed, the testing chamber 2 is sealed to prevent light leakage from affecting the testing.

[0046] The desktop colorimeter also includes a desktop computer 19, which contains a formula database. The probe 18 is communicatively connected to the desktop computer 19. The display screen of the desktop computer 19 is embedded in the colorimeter body 1 for easy viewing by the operator, and the host computer of the desktop computer 19 is located inside the colorimeter body 1. The probe 18 transmits the detected data to the desktop computer 19, which searches for the corresponding formula in the formula database based on the detection data (this is prior art and will not be described in detail here). Finally, the formula is displayed on the screen.

[0047] The desktop colorimeter also includes a protective device, which comprises a protective platform 20, a vertical rod 21, and a pressure sensor 22. The top of the protective platform 20 is fixedly connected to the top of the detection box 2, and the top of the vertical rod 21 is fixedly connected to the protective platform 20. The pressure sensor 22 is located at the bottom of the protective platform 20, below the vertical rod 21. An upper pressure sleeve 23, a second spring 24, and a lower pressure sleeve 25 are sequentially fitted onto the vertical rod 21 from top to bottom. The second spring 24 is fixedly connected to the upper pressure sleeve 23, and the lower pressure sleeve 25 contacts the pressure sensor 22. The upper pressure sleeve 23 is connected to the probe 18 via an L-shaped plate 26. This protective device provides lateral protection for the probe 18, allowing it to move vertically up and down. It also protects the probe 18 from excessive pressure that could damage it. Pressure sensor 22 is electrically connected to desktop computer 19. Pressure sensor 22 transmits the measured pressure value to desktop computer 19. Once the pressure measured by pressure sensor 22 exceeds the preset pressure threshold, desktop computer 19 issues a command to servo motor 8, causing servo motor 8 to stop working.

[0048] There is a 5mm gap between the pressure sensor 22 and the vertical rod 21.

[0049] The desktop colorimeter also includes a detection area qualification detection device, which consists of two laser rangefinders 27, symmetrically mounted on both sides of the probe 18. The area projected onto the object to be measured by the probe 18 is the detection area. Accuracy can only be guaranteed if the detection area is parallel or nearly parallel to the probe 18. The use of two laser rangefinders 27 solves this problem. Specifically, as long as the difference between the distances measured by the two laser rangefinders 27 is within the error range, the detection area is considered qualified.

[0050] The probe 18 has a silicone ring 28 at its bottom. The silicone ring 28 is designed to protect the bottom of the probe 18 and prevent damage to it. In addition, the silicone ring 28 has good elasticity, which allows it to form a tight fit with the object being tested, something that ordinary probes 18 cannot do.

[0051] A moving distance sensor 29 is installed on the top of the protective platform 20, and the moving distance sensor 29 is located above the probe 18.

[0052] The operating procedure for a benchtop color mixing instrument used in shoe sole production includes the following steps:

[0053] S1, Place the sole 16 into the clamp 9 to fix the sole 16;

[0054] S2, place the sole 16 under the side head 18;

[0055] S3, the inspection area qualification inspection device inspects the sole 16 to determine whether the inspection area is qualified. If the inspection area is not qualified, the sole 16 is adjusted so that the inspection area is parallel to the probe 18, and then the inspection continues until the inspection area is qualified.

[0056] The following conditions must be met for the detection area to be considered qualified: the distances measured by the two laser rangefinders 27 are D1 and D2, the difference between D1 and D2 is < ΔD, and ΔD = 2mm;

[0057] S4, calculate the moving distance L of probe 18, which satisfies the following condition: L=(D1+D2+d) / 2, where d is the thickness of silicone ring 28, d=5mm;

[0058] S5, the servo motor 8 controls the probe 18 to move downwards, and the moving distance sensor 29 monitors the distance Q between the moving distance sensor 29 and the probe 18. When Q = L + R, the probe 18 stops moving downwards, where R is the distance from the initial position of the probe 18 to the moving distance sensor 29. R is a constant, and the initial position of the probe 18 is the position where the probe 18 stops before moving downwards each time.

[0059] S6, the probe 18 detects the sole 16 and transmits the detection data to the desktop computer 19.
