Description

Technical Field

[0001] The invention relates to the technical field of colorimeter, and more particularly to a high-precision desktop colorimeter for sole production. Background Art

[0002] Colorimeters are divided into portable colorimeters and desktop colorimeters according to their size. Portable colorimeters are small and easy to carry, but their measurement accuracy is limited due to the size of the device. Desktop colorimeters have high-precision color measurement and color matching functions. Compared with portable colorimeters, they are larger in size, have higher measurement accuracy, and more stable performance. Therefore, desktop colorimeters are often used in scenarios where there is no need for mobility and high accuracy is required, such as when testing specific products in a production workshop.

[0003] To ensure measurement accuracy, the desktop colorimeter needs to ensure that the probe fits tightly with the object to be measured during measurement to avoid light leakage. For example, the Chinese invention patent with the authorization announcement number CN219935115U discloses a desktop colorimeter. When in use, the slide 6 normally covers the detection cavity 3, and the upper end of the longitudinal slider 11 moves into the detection cavity 3. First, the slide 6 is pushed upward to make the positioning slider 7 adsorbed on the upper top of the longitudinal slide groove 101, and then the kettle 5 is placed in the detection cavity 3. When it hits the longitudinal slider 11, the adjustment block 9 is pulled outward to separate the horizontal slider 8 from the longitudinal slider 11. At this time, the longitudinal slider 11 falls back into the placement groove 103, and then the kettle 5 continues to move toward the detection cavity 3. The other end of the measuring cavity 3 is pushed, and when it is located at the lower side of the measuring head 4 and the upper side of the longitudinal slider 11, the adjusting block 9 is released. During the resetting process, the tension spring 10 causes the transverse slider 8 to move toward the inner side 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, and then the slide plate 6 is moved to cover the detection cavity 3 again. Finally, the touch operation is performed through the touch screen 2, and the measuring head 4 is used to perform color difference detection on the kettle 5 in the detection cavity 3, which reduces the difficulty of electric kettle detection and improves the accuracy of electric kettle detection.

[0004] In the above patent, the elasticity of the tension spring 10 cannot be adjusted. If the elasticity of the tension spring 10 is too large, the kettle 5 and the probe 4 will be too close to each other, causing damage to the side head 4. The tension spring 10 will be deformed after repeated use and lose its original elasticity, which will reduce the contact force between the longitudinal slider 11 and the lower surface of the kettle 5, making it impossible for the probe 4 and the kettle 5 to fit tightly. Therefore, it is necessary to upgrade the structure and study a desktop colorimeter suitable for the soles. Summary of the invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a high-precision desktop colorimeter for sole production.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A high-precision desktop colorimeter for sole production, comprising a colorimeter body, on which a detection box is arranged; the characteristics are:

[0008] A sliding device is provided on the side wall of the detection box, and the sliding device includes a sliding seat, a screw rod and a slider, the slider is threadedly connected to the screw rod, and both ends of the screw rod are rotatably connected to the sliding seat, and a limit rod is provided on the sliding seat, and the lower end of the limit rod passes through the slider;

[0009] The slide is connected to the measuring head through a connecting wall;

[0010] A servo motor is provided on the top of the detection box, and the output shaft of the servo motor is connected to one end of the screw;

[0011] The desktop colorimeter also includes a qualified detection device for the detection area, which is composed of two laser distance measuring sensors, and the two laser distance measuring sensors are symmetrically installed on both sides of the measuring head;

[0012] There is a silicone ring at the bottom of the probe;

[0013] A mobile distance measuring sensor is arranged on the top wall of the detection box, and the mobile distance measuring sensor is located above the measuring head;

[0014] The method for using the desktop colorimeter comprises the following steps:

[0015] S1, putting the sole into the fixture to fix the sole;

[0016] S2, place the sole under the measuring head;

[0017] S3, the detection area is qualified. The detection device detects the sole to determine whether the detection area is qualified. If the detection area is not qualified, the sole is adjusted so that the detection area is parallel to the probe, and then the detection is continued until the detection area is qualified.

[0018] S4, the probe detects the sole and transmits the detection data to the desktop computer.

[0019] By setting a servo motor to drive the screw to rotate, the slider slides up and down along the limit rod, thereby driving the probe to be close to or separated from the object to be measured. In the present invention, the servo motor is controlled by a servo driver, which can provide high-precision and stable power output, which helps to improve the accuracy of the motor speed and position, so that the probe and the object to be measured are stably fitted and the accuracy of detection is improved.

[0020] In the present invention, the area projected by the probe onto the object to be measured is the detection area. Only when the detection area is parallel or nearly parallel to the probe can the detection accuracy be guaranteed. The above technical problems can be solved by setting two laser ranging sensors. Specifically, as long as the difference between the distances measured by the two laser ranging sensors is within the error range, it means that the detection area is qualified.

[0021] In the present invention, the silicone ring is used to protect the bottom of the probe to avoid damage to the probe. In addition, the silicone ring has good elasticity, so that the silicone ring and the object to be measured can form a tight fit, which is impossible for ordinary probes.

[0022] In S3, the detection area must meet the following conditions to be qualified: the distances measured by the two laser ranging sensors are D1 and D2, the difference between D1 and D2 is less than ΔD, ΔD = 2 mm;

[0023] In S4, the servo motor controls the probe to move downward, and the mobile distance sensor monitors the distance Q between the mobile distance sensor and the probe. When Q=L+R, the probe stops moving downward, where L=(D1+D2+d) / 2, d is the thickness of the silicone ring, and d=5 mm; R is the distance from the initial position of the probe to the mobile distance sensor, and R is a constant. The initial position of the probe is the stop position before the probe moves downward each time.

[0024] The desktop colorimeter also includes a fixture, which includes a grooved plate and a pressure plate. The grooved plate is provided with two parallel sliding sleeves, in which a sliding rod is inserted, and 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. The existing fixture is designed at the bottom of the detection box, and the fixture structure is complex. Generally, the sole surface is placed and fixed upward, but there are many heat dissipation holes on the sole surface. If it is directly facing the detection head, it will affect the detection. However, the existing fixture cannot adjust the position of the sole, thereby greatly reducing the accuracy of the detection. The side wall of the sole generally does not have heat dissipation holes. If the detection can be performed from the side wall of the sole, the detection accuracy can be increased. However, there is currently no fixture on the market that can stand up the side wall of the sole. Therefore, it is necessary to study a fixture with a simple structure and the ability to adjust the position of the sole. The fixture of the present invention can achieve the above functions. When in use, the pressure plate is pulled open and the sole is clamped to make the side wall of the sole stand up, and the side wall of the sole is placed under the measuring head. When the sole surface needs to be detected, the sole position is readjusted and then placed in the fixture for clamping. The fixture of the present invention can clamp different parts of the sole for multi-angle detection, and the sole can also be moved to avoid the heat dissipation holes to improve the detection accuracy.

[0025] The test box is equipped with a door cover. The object to be tested is placed in the test box by setting the door cover. When the door cover is closed, the test box is sealed to prevent light leakage from affecting the test.

[0026] The desktop computer is provided with a formula database, and the probe is connected to the desktop computer. The display screen of the desktop computer is embedded in the colorimeter body for the convenience of the staff to view, and the host of the desktop computer is arranged inside the colorimeter body. The probe transmits the detected data to the desktop computer, and the desktop computer searches for the corresponding formula in the formula database according to the detected data, which belongs to the prior art and is not specifically described in the present invention. Finally, the formula is displayed on the display screen.

[0027] The desktop colorimeter also includes a protective device, which includes 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, the top of the vertical rod is fixedly connected to the protective platform, and a pressure sensor is provided at the bottom of the protective platform. The pressure sensor is located below the vertical rod. An upper pressure sleeve, a second spring and a lower pressure sleeve are sequentially sleeved on the vertical rod from top to bottom. The second spring is fixedly connected to the upper pressure sleeve, and the lower pressure sleeve is in contact with the pressure sensor. The upper pressure sleeve is connected to the probe through an L-shaped plate. The side protection of the probe is achieved by setting up the protective device so that the probe can maintain vertical up and down movement. In addition, the probe is protected to prevent the probe from being damaged due to excessive pressure on the probe. The pressure sensor is electrically connected to a desktop computer, and the pressure sensor transmits the measured pressure value to the desktop computer. Once the pressure measured by the pressure sensor exceeds a preset pressure threshold, the desktop computer issues a command to the servo motor to stop the servo motor.

[0028] A gap of 5 mm is left between the pressure sensor and the vertical rod.

[0029] The beneficial effects of the present invention are as follows:

[0030] The servo motor provides high-precision and stable power output, which makes the probe and the object to be tested fit stably and improves the accuracy of detection; the fixture 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 detection accuracy.
