[0035] Example

[0036] See also Figure 1-6 The present invention provides a technical solution: a method for detecting the contour and position of a film, comprising the following steps:

[0037] S1. Print a plan drawing of the integrated busbar 2. Three groups of limiting columns 21 are fixed to one side of the top of the integrated busbar 2, and each group of limiting columns 21 has six columns.

[0038] S2. Processing the film body 1 according to the plane drawing, including the arc corners and through holes 11 of the film body 1; three groups of through holes 11 are opened on the surface of the film body 1, and each group of through holes 11 has six through holes.

[0039] S3, by the cooperation of the clamping assembly 4 and the lifting assembly 5, the through hole 11 is sleeved on the outer side of the limiting column 21;

[0040] The clamping assembly 4 includes two limit frames 41, the limit frames 41 are provided with a slide groove 410, the slide groove 410 is slidably connected to the inner side of the slide groove 410, a first slide column 44 is fixed to the top of the slide plate 49, a spring 42 is sleeved on the outer side of the first slide column 44, and the two ends of the spring 42 are respectively connected to the slide plate 49 and one side of the slide groove 410, a pull block 43 is fixed to the top of the first slide column 44, a second slide column 45 is fixed to the bottom of the slide plate 49, a cross plate 47 is fixed to the bottom of the second slide column 45, and the first slide column 44 is fixed to the bottom of the slide plate 49. The outer sides of 44 and the second sliding column 45 are movable and penetrate one side of the limit frame 41. A support frame 411 is fixed to the bottom of the limit frame 41. An insertion groove 48 is provided between the support frame 411 and the limit frame 41. The pull block 43 is pulled upward. At this time, the pull block 43 drives the first sliding column 44, the slide plate 49, the second sliding column 45 and the cross plate 47 to move upward, and then one side of the integrated busbar 2 is inserted into the inner side of the insertion groove 48. A number of rubber protrusions 46 are bonded to the opposite sides of the insertion groove 48 and the cross plate 47.

[0041] The lifting assembly 5 includes two fixing frames 51, a motor 53 is fixed to one side of the top of the fixing frame 51, a screw rod 55 is fixed to the output shaft end of the motor 53, the outer side of the screw rod 55 is threadedly connected to a connecting plate 54 fixed to one side of the limiting frame 41, a sliding rod 52 that movably passes through one side of the connecting plate 54 is fixed to the top of the fixing frame 51, a limiting block 57 is fixed to the top of the screw rod 55, when the screw rod 55 rotates clockwise, the screw rod 55 is threadedly connected to the connecting plate 54, so that the connecting plate 54 moves upward along the sliding rod 52, and the clamping assembly 4 and the film body 1 can be driven to move upward.

[0042] When it is necessary to use the film body 1 to detect the contour and position of the limit column 21 on one side of the integrated busbar 2, first pull the pull block 43 upward in sequence. At this time, the pull block 43 drives the first slide column 44, the slide plate 49, the second slide column 45 and the cross plate 47 to move upward, and then insert one side of the integrated busbar 2 into the inner side of the insertion groove 48, and then release the pulling force of the pull block 43. At this time, under the elastic force of the spring 42, the film body 1 can be clamped between the clamping components 4, and workers do not need to manually take the film body 1 and align it with the limit column 21 for detection. Pulling the pull block 43 can automatically clamp the film body 1, ensuring that the relative position between the film body 1 and the limit column 21 of the integrated busbar 2 is stable, reducing the error caused by human operation, and improving the accuracy and reliability of detection;

[0043] When the surface of the film body 1 is damaged after repeated use, it is only necessary to pull the pull block 43 upwards to make the rubber protrusion 46 at the bottom of the horizontal plate 47 leave the top of the film body 1. At this time, the film body 1 can be removed, and then a new film body 1 can be replaced to continue to detect the contour and position of the integrated busbar 2 and the top limit column 21. Simply pulling the pull block 43 can easily release the film body 1, realizing rapid replacement, and workers do not need to use complex tools or perform cumbersome operations;

[0044] When the film body 1 moves up and down, it is only necessary to control the output shaft of the motor 53 to drive the screw rod 55 to rotate clockwise or counterclockwise. When the screw rod 55 rotates clockwise, the screw rod 55 is threadedly connected with the connecting plate 54, so that the connecting plate 54 moves upward along the slide bar 52. At this time, the clamping assembly 4 and the film body 1 can be driven to move upward, waiting for the contour and position of the integrated busbar 2 and the limit column 21 to be detected. When the screw rod 55 rotates counterclockwise, the connecting plate 54 moves downward along the slide bar 52, driving the clamping assembly 4 and the film body 1 to move downward. At this time, the film body 1 and the through hole 11 are respectively connected to the integrated busbar 2 and the limit column 21 for contour and position detection. The motor 53 controls the clockwise or counterclockwise rotation of the screw rod 55, thereby realizing the up and down movement of the film body 1. The entire up and down movement process is driven by the motor 53, which realizes a high degree of automation, reduces manual intervention, and improves work efficiency and stability.

[0045] During the inspection, the staff uses a caliper to check the partial dimensions between the integrated busbar 2 and the film body 1 whose deviation exceeds the allowable range. At the same time, the two-dimensional measuring instrument 3 can also be used to measure the partial dimensions between the integrated busbar 2 and the film body 1 whose deviation exceeds the allowable range, and the detection data of the contour and position are displayed on the display screen 6. Combining the use of visual, caliper and two-dimensional measuring instrument 3, a variety of measurement methods are provided for the staff. The caliper is suitable for quick preliminary measurement, while the two-dimensional measuring instrument 3 is suitable for scenes requiring high-precision measurement, so that the staff can choose the most appropriate measurement tool according to the actual situation.

[0046] S4. Visually or using a caliper to check the contour and position deviation between the integrated busbar 2 and the film body 1; visual inspection can quickly find obvious deviations, and the caliper is suitable for quick preliminary measurement. Start the two-dimensional measuring instrument 3 to perform high-precision measurement of the contour and position deviation between the integrated busbar 2 and the film body 1, and display the test results on the display screen 6;

[0047] A display screen 6 is provided on one side of the two-dimensional measuring instrument 3, and the bottom of the fixing frame 51 is installed on the top of the measuring table of the two-dimensional measuring instrument 3. The two-dimensional measuring instrument 3 is suitable for scenes requiring high-precision measurement, so that the staff can choose the most suitable measuring tool according to the actual situation. As a high-precision measuring device, the two-dimensional measuring instrument 3 can provide more accurate measurement results, especially when detecting small deviations or complex contours. Its accuracy far exceeds that of traditional calipers, which helps to find more subtle deviations and ensure product quality.

[0048] S5. Evaluate the detection results of the contour and position of the integrated busbar 2.

[0049] Evaluation standards are established based on design requirements and technical specifications, and the allowable range of contour and position deviations is clarified. The measurement results are compared with the evaluation standards to determine whether there is a deviation and the size and nature of the deviation. If the deviation is within the allowable range, it is considered qualified; if the deviation exceeds the allowable range, the cause must be analyzed and corresponding corrective measures must be taken, such as reprocessing or replacing parts, to ensure that product quality meets the requirements.

[0050] In summary, the film body 1 can be automatically clamped by pulling the pull block 43, ensuring that a stable relative position is maintained between the film body 1 and the limit column 21 of the integrated busbar 2, reducing errors caused by human operation, improving the accuracy and reliability of detection, and eliminating the tedious steps of workers manually taking and aligning. Workers do not need to hold the film body 1 for a long time for alignment and detection, which reduces the physical burden of work, is beneficial to protecting the health of workers, greatly shortens the preparation time before detection, and improves overall work efficiency.

[0051] By simply pulling the pull block 43, the film body 1 can be easily released for quick replacement. Workers do not need to use complex tools or perform tedious operations. The replacement process is simple and intuitive, which reduces the requirements for workers' operating skills and experience. Timely replacement of damaged film bodies 1 can ensure the accuracy and reliability of detection results, avoid false detection or missed detection due to damage to the film body 1, and improve product quality.

[0052] The motor 53 controls the screw rod 55 to rotate clockwise or counterclockwise, thereby realizing the up and down movement of the film body 1. The entire up and down movement process is driven by the motor 53, achieving a high degree of automation, reducing manual intervention, and improving work efficiency and stability.

[0053] By combining the use of visual inspection, calipers and the two-dimensional measuring instrument 3, a variety of measurement methods are provided for workers. Visual inspection can quickly detect obvious deviations. Calipers are suitable for quick preliminary measurements, while the two-dimensional measuring instrument 3 is suitable for scenarios that require high-precision measurements, allowing workers to choose the most appropriate measurement tool based on actual conditions. As a high-precision measuring device, the two-dimensional measuring instrument 3 can provide more accurate measurement results, especially when detecting small deviations or complex contours. Its accuracy far exceeds that of traditional calipers, which helps to detect more subtle deviations and ensure product quality.
