Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, and in particular to a detection device for measuring the extension of a capacitor. Background Technology
[0002] In the sealing process of traditional capacitor manufacturing, after the capacitor is embedded in a thick plastic plate, the protrusion of the capacitor is typically measured using a multi-point sampling method. The obtained data serves as a reference for adjusting subsequent process parameters, allowing for flexible adjustment of parameters during the sealing process. Current practice involves manually confirming the protrusion of the product (capacitor) at the four corners and the center of a thick plastic plate using a protrusion measuring instrument, and calculating the average of the five values. The traditional measuring instrument is essentially an electronic digital dial indicator, a mechanical measuring tool that measures length using the principle of micrometer screws. It calculates the protrusion by measuring the values at the surface of the product and the surface of the thick plastic plate using a flat probe, and then calculating the difference between the two. The following factors affect manual measurement: 1. Due to the elasticity of the latex material, thick rubber sheets can cause changes in the protrusion of the contact area during contact measurement, resulting in localized indentation and deformation. This leads to deviations in measured values from the true dimensions, increasing measurement bias. 2. Different sizes or shapes of planar probes also affect the measured values. Smaller planar probes result in fewer samples per unit area subjected to force, greater pressure, and a greater likelihood of indentation, leading to a smaller measured protrusion. 3. There are non-negligible errors during manual operation. For example, a faster descent of the planar probe by hand results in a greater impact force on the product, making it more prone to indentation and leading to a smaller measured protrusion. 4. During manual measurement, the lack of standardized measurement positioning points, coupled with subjective judgment bias by the operator, makes it difficult to guarantee the spatial repeatability and consistency of the measurement position. This positioning offset directly causes systematic measurement errors, significantly impacting the repeatability and accuracy of data acquisition. 5. Moving other products during the measurement process can cause changes in the product's protrusion or product tilting. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] like Figure 1-4 As shown, a preferred embodiment of the present invention provides a detection device for measuring the extension of a capacitor, comprising a worktable 1, a transverse electric slide 2, a longitudinal electric slide 3, a loading stage 4, a fixing frame 5, a laser displacement sensor 6, and a controller (not shown in the figure). The transverse electric slide 2 is mounted on the worktable 1, and the longitudinal electric slide 3 is mounted on the transverse electric slide 2. The transverse electric slide 2 can drive the longitudinal electric slide 3 to move laterally. The loading stage 4 is used to fix a thick rubber plate 7, and the loading stage 4 is mounted on the longitudinal electric slide 3. The longitudinal electric slide 3 can drive the loading stage 4 to move laterally. When the thick rubber plate 7 is placed and fixed on the loading stage 4, the longitudinal electric slide 3 can drive the loading stage 4 and the thick rubber plate 7 to move longitudinally together. The transverse electric slide 2... The system can drive the longitudinal electric slide 3, the platform 4, and the thick rubber plate 7 to move laterally together. That is, the position of the thick rubber plate 7 can be adjusted by the transverse electric slide 2 and the longitudinal electric slide 3. The fixing frame 5 is fixed on the worktable 1. The fixing frame 5 is provided with a crossbar 51 located above the platform 4. In this embodiment, the fixing frame 5 is a gantry frame, that is, the fixing frame 5 also has two uprights. The two uprights are located on the transverse sides of the transverse electric slide 2, and the crossbar 51 is fixedly connected to the top of the two uprights. The laser displacement sensor 6 is installed on the crossbar 51. The detection end of the laser displacement sensor 6 is set downward. The controller is electrically connected to the laser displacement sensor 6. The laser displacement sensor 6 can detect the distance between itself and the object below it and transmit it to the controller.
[0021] The working principle of this embodiment is as follows: After the capacitor is placed in the thick plastic plate 7, the thick plastic plate 7 is placed and fixed on the stage 4, ensuring that the top surface of the thick plastic plate 7 is horizontal. At this time, the thick plastic plate 7 is located below the laser displacement sensor 6. The laser displacement sensor 6 can detect the vertical distance between itself and the top surface of the thick plastic plate 7 and feed it back to the controller. Then, by controlling the horizontal electric slide 2 and the vertical electric slide 3, the relative position of the thick plastic plate 7 and the laser displacement sensor 6 can be adjusted, so that the capacitor to be measured on the thick plastic plate 7 is located below the laser displacement sensor 6. In this way, the vertical distance from the top surface of the capacitor to the laser displacement sensor 6 is measured and fed back to the controller. The controller can then calculate the extension amount of the capacitor (the capacitor). The difference between the vertical distance from the top surface of the thick plastic plate 7 to the laser displacement sensor 6 and the vertical distance from the top surface of the thick plastic plate 7 to the laser displacement sensor 6 is used to repeatedly adjust the position of the thick plastic plate 7. This allows for the detection of the protrusion of multiple capacitors located at different positions on the thick plastic plate 7, and the final average value is calculated. This device uses the laser displacement sensor 6 for detection, eliminating the need for direct contact with the capacitors and the thick plastic plate 7, thus reducing the deviation of the overall measurement values and avoiding the side effects caused by manual contact with the product. It has high detection accuracy. The position of the thick plastic plate 7 can be adjusted by the horizontal electric slide 2 and the vertical electric slide 3, enabling rapid adjustment of different detection positions of the product. The controller can record multiple measurement values and perform simple data processing, resulting in high detection efficiency.
[0022] For example, the transverse electric slide 2 includes a first mounting base 21, a first lead screw 22, a first moving block 23, and a first motor 24. The first mounting base 21 is mounted on the worktable 1. The first lead screw 22 is arranged transversely and rotatably connected to the first mounting base 21. The first moving block 23 is threadedly connected to the first lead screw 22. The first motor 24 is mounted on the first mounting base 21 and connected to the first lead screw 22. The first motor 24 can drive the first lead screw 22 to rotate. The longitudinal electric slide 3 is mounted on the first moving block 23. The first motor 24 drives the first lead screw 22 to rotate, thereby driving the first moving block 23 to move along the axial direction (i.e., transverse) of the first lead screw 22, thereby driving the longitudinal electric slide 3 to move transversely.
[0023] For example, the longitudinal electric slide 3 includes a second mounting base 31, a second lead screw 32, a second moving block 33, and a second motor 34. The second mounting base 31 is mounted on the first moving block 23. The second lead screw 32 is arranged longitudinally and rotatably connected to the second mounting base 31. The second moving block 33 is threadedly connected to the second lead screw 32. The second motor 34 is mounted on the second mounting base 31 and connected to the second lead screw 32. The second motor 34 can drive the second lead screw 32 to rotate. The stage 4 is mounted on the second moving block 33. The second motor 34 drives the second lead screw 32 to rotate, thereby driving the second moving block 33 to move along the axial direction (i.e., longitudinal direction) of the second lead screw 32, thereby driving the stage 4 to move longitudinally.
[0024] For example, the top of the first mounting base 21 is provided with a first guide rail 25 arranged in a horizontal direction, and a first slider 26 is provided on the first guide rail 25. The top of the first slider 26 is fixedly connected to the bottom of the second mounting base 31. That is, the second mounting base 31 is fixedly connected to the first slider 26 and the first moving block 23 respectively. Through the cooperation of the first slider 26 and the first guide rail 25, it is ensured that the first moving block 23 can drive the second mounting base 31 to move horizontally.
[0025] For example, the first guide rail 25 is provided with two rails and is located on both sides of the longitudinal direction of the first mounting base 21, so that the second mounting base 31 can slide smoothly.
[0026] For example, the top of the second mounting base 31 is provided with a second guide rail 35 arranged in the longitudinal direction, and a second slider 36 is provided on the second guide rail 35. The top of the second slider 36 is fixedly connected to the bottom of the platform 4, that is, the platform 4 is fixedly connected to the second slider 36 and the second moving block 33 respectively. Through the cooperation of the second slider 36 and the second guide rail 35, it is ensured that the second moving block 33 can drive the platform 4 to move in the longitudinal direction.
[0027] For example, the second guide rail 35 has two rails and is located on both sides of the second mounting base 31, so that the platform 4 can slide smoothly.
[0028] For example, the stage 4 is provided with a positioning pin, and the thick rubber plate 7 is provided with a positioning hole that matches the positioning pin. The thick rubber plate 7 is positioned and fixed on the stage 4 by the cooperation of the positioning pin and the positioning hole.
[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
