A slicing device for automobile weather strip coating detection

Abstract

This utility model discloses a slicing device for detecting automotive sealing strip coatings, relating to the field of sealing strip detection technology. The device includes a base, a mounting frame fixed to the base, a fixing plate fixed inside the mounting frame, and a servo motor mounted at the top center of the mounting frame. The output end of the servo motor is connected to a lead screw, and a threaded sleeve is threaded onto the outer surface of the lead screw. During slicing, the operator places the sealing strip sample directly below two sets of cutters. After starting the servo motor, its rotation drives the lead screw to rotate synchronously. The linear movement of the threaded sleeve on the lead screw drives a sliding plate to move precisely downwards vertically via a connecting rod, allowing the two sets of cutters at the bottom of the sliding plate to cut the sealing strip at a constant interval. Because the cutter spacing is strictly controlled at 2mm, the slice thickness is ensured to remain consistently at 2mm for each cut, avoiding uneven thickness caused by force or angle deviations during manual operation.

Description

Technical Field

[0001] This utility model relates to the field of sealing strip testing technology, specifically a slicing device for testing automotive sealing strip coatings. Background Technology

[0002] Automotive sealing strips serve to fill various gaps and gaps between vehicle body components, and have functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration, improving the comfort of the driving experience and protecting the vehicle body. Before inspecting the coating of automotive sealing strips, the sealing strips need to be sliced ​​and then placed under a 3D laser confocal microscope for inspection.

[0003] The commonly used manual sectioning method in the industry mainly includes the following steps: First, cut a 5-10cm length of sealing strip and select an area with uniform coating; second, use a scalpel to remove the uneven part of the sample end to form a preliminary cutting surface; then, the scalpel blade must be kept strictly perpendicular to the sample surface (this is a critical operation, as tilting the blade will directly lead to deviations in subsequent coating thickness measurements); finally, advance the blade in one direction with steady force to avoid back-and-forth cutting that produces burrs, while controlling the section thickness to 1.5-2.5mm. However, this operation process has significant technical bottlenecks. On the one hand, manual operation is highly dependent on the operator's experience and skill, requiring precise control of the blade angle, advancement speed, and uniform force application. The steps are cumbersome and technically difficult, and novices find it difficult to quickly master the core skills of perpendicular cutting and uniform advancement. Operational deviations can easily lead to rough or uneven section surfaces, thus affecting the observation accuracy of the coating structure under the microscope. On the other hand, because the blade is sharp and the hand is very close to the blade during operation, there is a safety hazard of the blade slipping and cutting fingers. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a slicing device for detecting automotive sealing strip coatings, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slicing device for detecting automotive sealing strip coatings, comprising a base, a mounting frame fixed to the base, a fixing plate fixed inside the mounting frame, a servo motor mounted at the top center of the mounting frame, a lead screw connected to the output end of the servo motor, a threaded sleeve threaded to the outer surface of the lead screw, connecting rods fixed to both sides of the threaded sleeve, a sliding plate fixed to the bottom end of the connecting rod, and two sets of cutters mounted at the bottom of the sliding plate; a push plate fixed to the bottom center of the fixing plate; two sets of connecting plates fixed to the outer surface of the base, and a support plate rotatably connected to the inner sides of the two sets of connecting plates via a connecting shaft.

[0006] Furthermore, the inner wall of the mounting bracket is provided with a sliding groove, and the sliding plate slides in conjunction with the sliding groove.

[0007] By adopting the above technical solution, the slide plate moves up and down more stably under the action of the slide groove, and will not deviate, thus making the slicing more accurate.

[0008] Furthermore, the gap between the two sets of cutters is 2mm, and the pusher is located between the two sets of cutters.

[0009] By adopting the above technical solution, the servo motor drives the lead screw to drive the slide plate so that the two sets of cutters with a 2mm gap can accurately cut the sealing strip, and the push plate can realize automatic unloading.

[0010] Furthermore, the top of the cutter is bolted to the bottom of the slide plate, and a magnetic plate is embedded in the bottom of the slide plate.

[0011] By adopting the above technical solution, the top of the cutter can be detachably installed on the bottom of the slide plate by bolts, which facilitates quick replacement and maintenance after the blade wears out. When installing a new cutter, first attach the cutter to the bottom of the magnetic plate, and then tighten the bolts. This makes the installation more convenient.

[0012] Furthermore, the pusher plate slides in conjunction with the slide plate, and the connecting rod slides in conjunction with the fixed plate.

[0013] By adopting the above technical solution, when the slide plate drives the cutter to reset, the pusher pushes the slice out from the cutter gap through sliding displacement. The connecting rod slides with the fixed plate to ensure that the connecting rod moves vertically along the guide groove of the fixed plate when the screw rotates, thereby driving the slide plate to rise and fall accurately and avoiding deviation.

[0014] Furthermore, the support plate is L-shaped, and a pressing plate is fixed to one side of the top of the support plate.

[0015] By adopting the above technical solution, the design transforms the manual sheet picking operation into a pressing and unloading action through the cooperation of the pressing plate and the L-shaped support plate, avoiding the safety hazard of the hand approaching the cutting area. That is, the worker tilts the support plate by pressing the plate, thereby moving the sheet away from directly under the cutting blade.

[0016] Furthermore, a gasket is provided on the top of the support plate, and two sets of grooves are provided directly above the gasket.

[0017] By adopting the above technical solution, this design avoids direct rigid collision between the cutter and the support plate through the limiting and guiding of the groove, and prevents the blade from being worn by impact or the surface of the support plate from being damaged.

[0018] Furthermore, the bottom of the base is provided with a friction pad, which is made of rubber material.

[0019] By adopting the above technical solution, the friction pad makes the device more stable and can effectively prevent the equipment from shifting due to the vibration generated by the servo motor during the slicing process.

[0020] Furthermore, the outer surface of the mounting bracket is provided with a control panel, and the servo motor is electrically connected to the control panel.

[0021] By adopting the above technical solution, the direction and start / stop of the servo motor can be controlled through the control panel, which not only reduces the technical threshold for operators, but also avoids the safety hazards of direct manual contact with the cutting blade.

[0022] In summary, the present invention has the following main advantages: 1. This utility model includes a servo motor, a lead screw, a threaded sleeve, a connecting rod, a sliding plate, and two sets of cutters, with a 2mm gap between the two sets of cutters. When slicing, the operator places the sealing strip sample directly under the two sets of cutters. After the servo motor is started, its rotation drives the lead screw to rotate synchronously. The linear movement of the threaded sleeve on the lead screw drives the sliding plate to move precisely downward in the vertical direction through the connecting rod, so that the two sets of cutters at the bottom of the sliding plate cut the sealing strip at a constant gap. Since the cutter gap is strictly controlled at 2mm, it can ensure that the slice thickness is stably maintained at 2mm each time, and avoid the problem of uneven thickness caused by force and angle deviations during manual operation. 2. Based on the above-mentioned configuration, this utility model also includes a set of push plates, a support plate, and a connecting shaft fixed between the two sets of cutters. After slicing is completed, the operator controls the servo motor to rotate in the opposite direction, thereby driving the slide plate to move the cutter upwards to reset. When the slide plate rises to a specific position, the push plate will automatically push the sheet stuck between the two sets of cutters down to the horizontal surface of the support plate below. At this time, the operator only needs to apply downward pressure to the pressing end of the support plate. Under the action of the rotation fulcrum of the connecting shaft, the support plate tilts to form a sliding slope, and the sheet will automatically slide along the tilted support plate to one side edge, making it easy for the operator to safely pick it up with tweezers. This design, through the cooperation of the push plate and the support plate, avoids the safety hazard of having to reach under the cutter when manually picking up the sheet, making the operator's operation safer.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] Example 1: A slicing device for detecting coatings on automotive sealing strips, such as... Figures 1-6 As shown, the device includes a base 1, with a friction pad 15 at its bottom. The friction pad 15 is made of rubber material, which makes the device more stable and effectively prevents displacement caused by vibration of the servo motor 4 during the slicing process. A mounting bracket 2 is fixed to the base 1, and a fixing plate 3 is fixed inside the mounting bracket 2. A servo motor 4 is mounted at the top center of the mounting bracket 2. The output end of the servo motor 4 is connected to a lead screw 6. A threaded sleeve 7 is threaded onto the outer surface of the lead screw 6. Connecting rods 8 are fixed to both sides of the threaded sleeve 7. A sliding plate 9 is fixed to the bottom of the connecting rods 8, and two sets of cutters 17 are mounted on the bottom of the sliding plate 9. A groove 10 is formed on the inner wall of the mounting bracket 2, and the sliding plate... The slide plate 9 slides in conjunction with the slide groove 10. Under the action of the slide groove 10, the slide plate 9 moves up and down more stably and will not deviate, thus making the slicing more accurate. The bottom center of the fixed plate 3 is fixed with a push plate 19. The outer surface of the base 1 is fixed with two sets of connecting plates 11, and the inner side of the two sets of connecting plates 11 is rotatably connected to a support plate 13 through a connecting shaft 12. The support plate 13 is L-shaped, and a pressing plate 14 is fixed on one side of the top of the support plate 13. This design transforms the manual sheet picking operation into a pressing unloading action by cooperating with the pressing plate 14 and the L-shaped support plate 13, avoiding the safety hazard of the hand approaching the area of ​​the cutter 17. That is, the worker tilts the support plate 13 by pressing the plate 14, thereby moving the sheet away from directly below the cutter 17.

[0028] See Figure 1 , Figure 3 , Figure 5 and Figure 6In the above embodiment, the gap between the two sets of cutters 17 is 2mm, the pusher 19 is located between the two sets of cutters 17, the servo motor 4 drives the lead screw 6 to drive the slide plate 9 so that the two sets of cutters 17 with a 2mm gap can accurately cut the sealing strip, and the pusher 19 can realize automatic unloading.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 In the above embodiment, the pusher 19 is slidably engaged with the slide plate 9, and the connecting rod 8 is slidably engaged with the fixing plate 3. When the slide plate 9 drives the cutter 17 to reset, the pusher 19 pushes the slice out from the gap of the cutter 17 through sliding displacement. The connecting rod 8 is slidably engaged with the fixing plate 3 to ensure that when the lead screw 6 rotates, the connecting rod 8 moves vertically along the guide groove of the fixing plate 3, driving the slide plate 9 to rise and fall accurately and avoid deviation.

[0030] See Figure 1 and Figure 4 In the above embodiment, a pad 20 is provided on the top of the support plate 13, and two sets of cutting grooves are provided directly above the pad 20. This design avoids the cutter 17 from directly colliding with the support plate 13 through the limiting and guiding of the cutting grooves, and prevents the blade from being worn by impact or the surface of the support plate 13 from being damaged.

[0031] See Figure 1 In the above embodiment, the outer surface of the mounting bracket 2 is provided with a control panel 5, and the servo motor 4 is electrically connected to the control panel 5. The direction of the servo motor 4 and its start and stop can be controlled through the control panel 5, which not only reduces the technical threshold for operators, but also avoids the safety hazards of direct manual contact with the cutter 17.

[0032] Example 2: To make blade replacement more convenient, Example 2 is an improvement on Example 1. (See attached document.) Figure 5 and Figure 6 The top of the cutter 17 is mounted to the bottom of the slide plate 9 by bolts 18. A magnetic plate 16 is embedded in the bottom of the slide plate 9. The top of the cutter 17 can be detachably mounted to the bottom of the slide plate 9 by bolts 18, which facilitates quick replacement and maintenance after the blade wears out. When installing a new cutter 17, first attach the cutter 17 to the bottom of the magnetic plate 16, and then tighten the bolts 18. This makes installation more convenient.

[0033] The implementation principle of this utility model is as follows: The operator first places the sealing strip sample directly below the two sets of cutters 17. The lead screw 6 at the output end of the servo motor 4 starts to rotate, driving the threaded sleeve 7 to move axially along the lead screw 6. The connecting rods 8 on both sides of the threaded sleeve 7 then drive the slide plate 9 to move vertically downward in the slide groove 10 on the inner wall of the mounting frame 2, so that the two sets of cutters 17 at the bottom of the slide plate 9 cut the sealing strip at a constant interval. Since the interval of the cutters 17 is strictly controlled at 2mm, it can be ensured that the thickness of the slice is stably maintained at 2mm each time. After the slice is completed, the servo motor 4 rotates in the opposite direction to drive the slide plate 9 to reset. The pusher 19 located between the two sets of cutters 17 slides and engages with the slide plate 9. During the upward movement of the slide plate 9, the pusher 19 pushes the slice out from the gap of the cutters 17 and drops it onto the support plate 13. At this time, the operator presses the pressing plate 14 on the top of the support plate 13. The support plate 13 tilts around the connecting shaft 12 to form a slide, so that the slice slides to the edge for easy picking up with tweezers.
