Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0033] Referring to Figures 1-7, this utility model provides a film thickness measuring device for measuring the film thickness of product 1. Product 1 is fixed on fixture 2 and moves along conveyor chain 3 with fixture 2. The film thickness measuring device includes a ground rail 4 set on the side of conveyor chain 3, a motion platform 5 set on the ground rail 4, and a drive assembly 8 that drives the motion platform 5 to move along the ground rail 4. The movement speed of the motion platform 5 is the same as the movement speed of the conveyor chain 3. The motion platform 5 is equipped with a clamping and lifting assembly 6 and a measuring assembly 7. The clamping and lifting assembly 6 is used to clamp fixture 2 and drive fixture 2 to move up and down to detach from conveyor chain 3. The measuring assembly 7 is used to measure the film thickness of product 1 during the movement. This utility model, through the measuring assembly 7 that moves synchronously with product 1, eliminates the need for manual removal of product 1 from conveyor chain 3. Then, contact-type film thickness measurement is performed simultaneously during the production process of product 1. This enables online non-contact surface measurement, which greatly improves measurement efficiency and saves a lot of time compared to the traditional manual contact-type point measurement method, meeting the testing needs of large-scale production. In addition, the clamping and lifting assembly 6 can clamp and lift the fixture 2, allowing the fixture 2 to be detached from the conveyor chain 3. This effectively avoids the impact of product 1 shaking caused by the unstable transport of the conveyor chain 3 on the measurement results, ensuring the stability of the measurement process and the accuracy of the measurement data. At the same time, rapid and accurate film thickness measurement helps to promptly identify product quality problems, allowing operators to adjust the production process in a timely manner, reducing the generation of defective products, thereby improving the production efficiency and product quality of the entire production line.
[0034] Referring to Figure 3, as an embodiment of this utility model, the clamping and lifting assembly 6 includes a clamping and lifting frame disposed on the motion platform 5. The clamping and lifting frame is provided with a lifting component and a clamping component. The clamping component is used to clamp the fixture 2. A first guide rail slider group 61 is provided between the clamping component and the clamping and lifting frame. The lifting component pushes the fixture 2 or the clamping component to move up and down along the first guide rail slider group 61. After the clamping component completes clamping of the fixture 2, the lifting component drives the fixture 2 and the clamping component to be lifted as a whole, realizing the separation of the fixture 2 from the conveyor chain 3. This provides a stable measurement environment for subsequent film thickness measurement, effectively avoiding the impact of product 1 shaking caused by the unstable transport of the conveyor chain 3 on the measurement results, and ensuring the stability of the measurement process and the accuracy of the measurement data. The first guide rail slider group 61 can guide the lifting and lowering of the clamping component and the fixture 2, improving the stability of the lifting and lowering process of the clamping component and the fixture 2.
[0035] As one embodiment of this utility model, the clamping lifting frame includes a first frame 621 and a second frame 622 symmetrically arranged. A connecting frame 623 is provided between the bottom of the first frame 621 and the bottom of the second frame 622. A traveling space 624 for the tool 2 to pass through is provided between the first frame 621 and the second frame 622. The clamping component can adopt various structures, such as the clamping component being only set on the first frame 621, or the clamping component being only set on the second frame 622, or the clamping component being set on both the first frame 621 and the second frame 622. When the tool 2 moves into the traveling space 624 following the conveyor chain 3, the clamping component clamps the tool 2. The traveling space 624 can effectively reduce the space around the tool 2, thereby improving the clamping accuracy and clamping stability of the clamping component on the tool 2.
[0036] As an embodiment of this utility model, the clamping component includes a first cylinder 631 disposed on the first frame 621, a first push block 632 disposed on the driving end of the first cylinder 631, a second cylinder 633 disposed on the second frame 622, and a second push block 634 disposed on the driving end of the second cylinder 633. The first push block 632 and the second push block 634 are disposed opposite to each other. When the fixture 2 reaches the clamping position, the first cylinder 631 and the second cylinder 633 act simultaneously, respectively driving the first push block 632 and the second push block 634 to move simultaneously toward the fixture 2, and finally clamping and fixing the fixture 2 in the travel space 624 through the first push block 632 and the second push block 634. Since the pushing force of the first push block 632 and the second push block 634 on the fixture 2 is equal in magnitude and opposite in direction, the force on the fixture 2 in the horizontal direction is 0, avoiding the phenomenon of the fixture 2 shifting during the clamping process, and effectively improving the stability and reliability of the clamping process.
[0037] Preferably, multiple clamping components are provided. By using multiple clamping components, i.e., a combination of multiple sets of first push blocks 632 and second push blocks 634, the tooling 2 is clamped at multiple positions, which can effectively improve the overall stability of clamping the tooling 2. The multiple clamping components are evenly distributed on the edge of the clamping lifting frame, which can avoid the clamping components interfering with or obstructing the product 1 during the clamping of the tooling 2, and avoid unnecessary impact on the subsequent film thickness measurement of the product 1. Preferably, there are four clamping components, i.e., four first cylinders 631 and four second cylinders 633. Two first cylinders 631 are located on the left side of the first frame 621, and the other two first cylinders 631 are located on the right side of the first frame 621. Similarly, two second cylinders 633 are located on the left side of the second frame 622, and the other two second cylinders 633 are located on the right side of the second frame 622, so as to clamp the side of the tooling 2, avoid the clamping components interfering with or affecting the lifting components, and improve the overall reliability and stability.
[0038] In one embodiment of this utility model, the lifting component includes a cylinder mounting plate 641 disposed at the bottom of the clamping lifting frame, a third cylinder 642 disposed on the cylinder mounting plate 641, and a third push block 643 disposed at the driving end of the third cylinder 642. The third push block 643 pushes the tooling 2 or the clamping component to lift or lower. Preferably, there are two third cylinders 642 and two third push blocks 643, with the two third cylinders 642 evenly disposed at the bottom of the clamping lifting frame, so as to apply an upward pushing force to the tooling 2 from multiple positions, thereby improving the stability of lifting the tooling 2. Similarly, the number of third cylinders 642 and third push blocks 643 can be increased, such as three or four, etc., and can be increased or decreased according to specific usage requirements. Preferably, the width of the contact surface between the third push block 643 and the tooling 2 is L, and the width of the contact surface between the tooling 2 and the third push block 643 is X, satisfying L≥X, which can ensure that the third push block 643 effectively pushes the tooling 2, improving the stability of the lifting process of the tooling 2.
[0039] Referring to Figure 4, as an embodiment of this utility model, the measuring component 7 includes a measuring frame 71 mounted on the motion platform 5 and a film thickness measuring device 72 mounted on the measuring frame 71. Preferably, the measuring frame 71 is provided with a measuring motor 73 and a measuring moving plate 74 driven by the measuring motor 73. The film thickness measuring device 72 is mounted on the measuring moving plate 74. The measuring motor 73 drives the measuring moving plate 74 to carry the film thickness measuring device 72 in reciprocating motion, so that the film thickness measuring device 72 can perform multi-directional detection on the product 1, and can also detect multiple products 1 on the same tooling 2, thereby improving detection efficiency. A second guide rail slider group 75 is provided between the film thickness measuring device 72 and the measuring frame 71, which can guide the movement of the measuring moving plate 74 and the film thickness measuring device 72, improve the stability of the movement of the measuring moving plate 74 and the film thickness measuring device 72, and improve the accuracy and reliability of the measurement results.
[0040] Referring to Figures 5 and 6, as an embodiment of this utility model, the drive assembly 8 includes a drive motor 81 mounted on the motion platform 5, a drive gear 82 mounted on the drive end of the drive motor 81, and a drive rack 83 mounted on the ground rail 4. A third guide rail slider group 84 is provided between the motion platform 5 and the ground rail 4. The drive motor 81 drives the drive gear 82 to rotate and mesh with the drive rack 83, so that the motion platform 5 moves on the ground rail 4.
[0041] As an embodiment of this utility model, the film thickness measuring device also includes a control cabinet 9. The control cabinet 9 is equipped with a controller and a display that are electrically connected. The controller is electrically connected to the drive component 8, the clamping and lifting component 6, and the measuring component 7. The controller centrally controls the drive component 8, the clamping and lifting component 6, and the measuring component 7. The specific operating parameters of the drive component 8, the clamping and lifting component 6, and the measuring component 7 can be displayed on the display in real time for easy confirmation by the staff.
[0042] During operation: When product 1 moves to the measurement area along the conveyor chain 3, the drive motor 81 starts. Through the cooperation of the drive gear 82 and the drive rack 83, the motion platform 5 moves on the ground rail 4 at the same speed as the conveyor chain 3, ensuring the synchronization of the two. The clamping and lifting assembly 6 starts to work. The first cylinder 631 and the second cylinder 633 drive the first push block 632 and the second push block 634 to move, clamping the fixture 2. Then, the third cylinder 642 drives the third push block 643 to rise, driving the fixture 2 and product 1 to rise, so that the fixture 2 is separated from the conveyor chain 3, avoiding the influence of product 1 shaking on the measurement. The measurement assembly 7 starts to work. The measurement motor 73 drives the measurement moving plate 74 to move, adjusting the position of the film thickness measuring device 72, and measuring the film thickness at different positions on the surface of product 1.
[0043] After measurement: The third cylinder 642 drives the third pusher block 643 to descend, causing the fixture 2 and product 1 to fall back onto the conveyor chain 3. The first cylinder 631 and the second cylinder 633 drive the first pusher block 632 and the second pusher block 634 to release the fixture 2. The motion platform 5 returns to its initial position under the action of the drive motor 81, awaiting the next measurement task. The operator can evaluate the product quality based on the measurement data. If the film thickness is found to be unsatisfactory, adjustments can be made to the spraying process in a timely manner to ensure product quality.
[0044] In summary, this utility model provides a film thickness measurement device. Through the measurement component 7, which moves synchronously with the product 1, it eliminates the need for manual removal of the product 1 from the conveyor chain 3 for contact film thickness measurement. Film thickness measurement is performed simultaneously during the production process of the product 1, enabling online non-contact surface measurement. Compared to traditional manual contact point measurement, this significantly improves measurement efficiency, saves considerable time, and meets the testing needs of large-scale production. Furthermore, the clamping and lifting component 6 can clamp and lift the fixture 2, detaching it from the conveyor chain 3. This effectively avoids the impact of product 1 vibration caused by unstable transport on the conveyor chain 3 on the measurement results, ensuring the stability of the measurement process and the accuracy of the measurement data. Simultaneously, through rapid and accurate film thickness measurement… This facilitates timely detection of product quality issues, allowing operators to adjust production processes promptly, reducing the generation of defective products, and thus improving the overall production efficiency and product quality of the production line. The lifting component raises the tooling 2 and clamping components as a whole, separating the tooling 2 from the conveyor chain 3. This provides a stable measurement environment for subsequent film thickness measurement, effectively avoiding the impact of product 1 shaking caused by unstable transport on the conveyor chain 3 on the measurement results, ensuring the stability of the measurement process and the accuracy of the measurement data. The measuring motor 73 drives the measuring moving plate 74 to carry the film thickness measuring device 72 in reciprocating motion, enabling the film thickness measuring device 72 to perform multi-directional detection of product 1, and also to detect multiple products 1 on the same tooling 2, improving detection efficiency.

Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
