Description

Technical Field

[0001] This invention relates to the field of curvature detection technology, and more specifically to an ABS sheet curvature detection device. Background Technology

[0002] ABS sheets, as an important type of engineering plastic sheet, are widely used in automobile manufacturing, home appliances, electronic instruments, and building decoration. The flatness of the sheet is one of the key indicators for measuring its quality, directly affecting the quality of subsequent processing steps and the performance of the final product.

[0003] For the quality inspection of the curvature of plastic sheets such as ABS sheets, manual sampling is usually used. The operator places the ABS sheet to be tested on a platform or a well-lit observation area. The operator observes the flatness of the sheet surface with the naked eye and uses a ruler or straightedge to measure the gaps to determine whether the sheet is warped or bent.

[0004] The test results are highly dependent on the operator's personal experience, visual acuity, and judgment standards. Different people may perceive and evaluate the same gap differently, resulting in inconsistent test results. At the same time, when dealing with batch sampling, operators need to maintain a high level of concentration for a long time to observe and judge, which can easily lead to visual fatigue. This not only reduces the efficiency of the test, but may also increase the risk of misjudgment and missed detection due to fatigue. Summary of the Invention

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-9 The present invention provides an ABS sheet bending test device, including a housing 8, with an outer shell 7 fixed to the top of the housing 8 by bolts. Two symmetrically arranged door panels 701 are provided on one side of the outer shell 7. The door panels 701 facilitate the operation of the operator to pick up and put down the ABS sheet. At the same time, the outer shell 7 can effectively protect the internal components of the equipment, prevent external impurities from entering and affecting the test, and also prevent the operator from accidentally touching the equipment parts during the test, which could cause safety issues.

[0031] like Figure 2 As shown, in this embodiment, a fixing frame 10 is fixed to the upper surface of the housing 8 by bolts. A detection component 1 is provided on one side of the fixing frame 10. The detection component 1 is used to detect the curvature of the ABS sheet. The detection component 1 includes a first linear motor 101 fixed to one side of the fixing frame 10 by bolts. A second linear motor 102 is fixed to the bottom of the first linear motor 101 by bolts. The first linear motor 101 and the second linear motor 102 are perpendicular to each other. The perpendicular arrangement allows the first linear motor 101 to drive the second linear motor 102 to move left and right, while the second linear motor 102 can drive the component at its bottom to move back and forth. Through the synergistic effect of the two, the distance sensor 104 can be driven to achieve multi-directional position adjustment in the horizontal plane, thereby flexibly detecting the curvature of different areas on the surface of the ABS sheet. It should be noted that the first linear motor 101 and the second linear motor 102 are both existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0032] like Figure 3 As shown, in this embodiment, the bottom of the second linear motor 102 is fixed with a fixing block 103 by bolts. The bottom of the fixing block 103 is detachably connected with a distance sensor 104 by bolts. The detachable distance sensor 104 facilitates the replacement and maintenance of the distance sensor 104. The two sides of the fixing block 103 are provided with swing components 2 for increasing the detection range of the distance sensor 104. The swing assembly 2 includes a swing frame 203 rotatably connected to both sides of the fixed block 103 via bearings. A second roller 201 is provided between the inner walls of both sides of the swing frame 203. The lowest point of the second roller 201 protrudes from the lower surface of the swing frame 203, thereby ensuring that the second roller 201 will contact the ABS plate first. Furthermore, the second roller 201 is parallel to the second linear motor 102, thereby ensuring that when the detection component 1 drives the second roller 201 to move on the surface of the ABS plate, the second roller 201 can roll along the curved surface of the ABS plate. As the height of the ABS plate changes, the swing frame 203 will swing around the rotational connection with the fixed block 103 accordingly. A baffle 202 is welded between the inner walls of the two sides of the swing frame 203. One side of the baffle 202 extends outward and beyond one side of the swing frame 203, and the baffle 202 is located below the distance sensor 104, so that the detection end of the distance sensor 104 is located above the baffle 202, so that the distance sensor 104 can detect the position change of the baffle 202. When the second roller 201 rolls on the surface of the ABS board and drives the swing frame 203 to swing due to the bending of the board, the baffle 202 will move synchronously with the swing frame 203, and the relative position between the baffle 202 and the distance sensor 104 changes. At this time, the distance sensor 104 can detect the change in distance between itself and the baffle 202, which indirectly reflects the height difference on the surface of the ABS board, thereby realizing the detection of the curvature of the board. This solves the problems of poor consistency, low efficiency and easy misjudgment and missed detection caused by traditional manual inspection relying on visual observation and experience judgment.

[0033] It should be noted that the distance sensor 104 in this application is prior art. The distance sensor 104 can be of model ZW-TOF3000N. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0034] During the inspection process, since the second roller 201 has a certain length, when the second linear motor 102 drives the second roller 201 to move along the width direction of the ABS plate, it can continuously detect the bending of the ABS plate in the area pressed by the second roller 201, avoiding the limitations that may exist in single-point detection and improving the comprehensiveness and efficiency of the inspection.

[0035] like Figure 4As shown, in this embodiment, the upper surface of the housing 8 is provided with a rotating shell 9, which is used to support the ABS sheet. The detection component 1 is located above the rotating shell 9 to detect the bending degree of the ABS sheet on the rotating shell 9. The upper surface of the housing 8 is provided with a through groove 11, and a rotating component 3 for rotating the rotating shell 9 is provided in the through groove 11. The rotating component 3 includes a carrier plate 301 welded in the through groove 11. A gap 1101 is left between the carrier plate 301 and the through groove 11. The gap 1101 is used for the pipeline to pass through, so as to avoid the pipeline from getting tangled or pulled when the rotating shell 9 rotates.

[0036] The bottom of the carrier plate 301 is fixed with a self-locking geared motor 302 that drives the rotating shell 9 to rotate. When the self-locking geared motor 302 is started, the output shaft of the self-locking geared motor 302 can drive the rotating shell 9 to rotate 90 degrees, so that the ABS plate placed on the rotating shell 9 can rotate synchronously. The bending degree detection of the ABS plate in different directions avoids the problem that the bending part of the ABS plate is parallel to the length direction of the second roller 201, which would lead to the inability to accurately detect the bending condition. Thus, the bending degree detection of the ABS plate in multiple directions is realized, further improving the comprehensiveness of the detection. The output shaft of the self-locking geared motor 302 can drive the rotating shell 9 to rotate, and the rotating shell 9 drives the ABS plate to rotate. This can adjust the misplaced ABS plate to a position parallel to the length direction of the second roller 201, ensuring that the detection component 1 can accurately detect the preset detection area of ​​the ABS plate and avoid deviations caused by the placement angle of the plate.

[0037] It should be noted that the self-locking geared motor 302 in this application is prior art. The self-locking geared motor 302 is a speed reduction transmission device that integrates a self-locking function. Its core feature is that it achieves "reverse self-locking" through a mechanical structure (such as a worm gear) - that is, the output shaft (load end) can only be driven to rotate by the input shaft (motor end), and the load reaction force of the output shaft cannot make the input shaft rotate in the opposite direction. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0038] like Figure 5 As shown, in this embodiment, the bottom inner wall of the rotating shell 9 is provided with an adsorption component 4 and a hydraulic component 5. The adsorption component 4 is used to fix the ABS plate. The adsorption component 4 includes a first manifold 401 fixed to the bottom inner wall of the rotating shell 9 by bolts. A first hose 402 connected to the first manifold 401 is installed at the bottom of the first manifold 401. The first hose 402 passes through the gap 1101 and is connected to the shell 8 and the external air extraction pipe, so that the first manifold 401 can be evacuated by the external air extraction device. When the air extraction pipe is evacuated, the first hose 402 forms a negative pressure inside the first manifold 401.

[0039] The upper surface of the rotating shell 9 has multiple equidistantly distributed through holes 403. A connecting tube 404 is slidably connected inside the through holes 403. A suction cup 405 connected to the connecting tube 404 is glued to the top of the connecting tube 404. A third flexible tube 406 connected to the connecting tube 404 is glued to the outside of the connecting tube 404. The other end of the third flexible tube 406 is fixed and connected to the first manifold 401. The negative pressure formed in the first manifold 401 is transmitted to the multiple connecting tubes 404 through the multiple third flexible tubes 406, thereby generating suction inside the multiple suction cups 405. Under the action of negative pressure, the multiple suction cups 405 are tightly adsorbed onto the surface of the ABS sheet, realizing the stable fixation of the ABS sheet and effectively preventing the ABS sheet from shifting during subsequent processing.

[0040] like Figure 6 As shown, in this embodiment, the hydraulic component 5 is used to adapt the adsorption component 4 to the curved ABS plate. The hydraulic component 5 includes a second manifold 501 fixed to the inner wall of the bottom of the rotating housing 9 by bolts. A second hose 502 connected to the second manifold 501 is installed at the bottom of the second manifold 501. A hydraulic oil tank 507 is installed on the upper surface of the housing 8. The second hose 502 passes through the gap 1101 and is connected to the housing 8 and the hydraulic oil tank 507. A through-hole vent 508 is opened at the top of the outer side of the hydraulic oil tank 507. The vent 508 ensures that the inside of the hydraulic oil tank 507 is connected to the outside atmosphere. The hydraulic oil in the hydraulic oil tank 507 is higher than the height of the suction cup 405. Therefore, the hydraulic oil in the hydraulic oil tank 507 can flow into the second manifold 501 through the second hose 502 due to gravity. The second flexible hose 502 is equipped with a solenoid valve 506, which controls the opening and closing of the second flexible hose 502. The top of the second manifold 501 is open, and multiple equally spaced sliding cylinders 503 are welded to the top of the second manifold 501. The sliding cylinders 503 are connected to the second manifold 501, and the multiple sliding cylinders 503 correspond one-to-one with multiple connecting pipes 404, ensuring that each connecting pipe 404 can be independently adjusted in height by corresponding to a sliding cylinder 503. A piston block 505 is slidably connected inside the sliding cylinder 503, and the bottom of the connecting pipe 404 is welded with... There is a connecting rod 504, the bottom end of which is fixed to the piston block 505. The hydraulic oil in the second manifold 501 flows into multiple slide cylinders 503 respectively. The thrust of the hydraulic oil flowing down from the top is greater than the overall weight of the piston block 505, the connecting rod 504, the connecting pipe 404 and the suction cup 405. Therefore, it can push the piston block 505 in the slide cylinder 503 to slide upward. The piston block 505 drives the connecting pipe 404 and the suction cup 405 to rise synchronously through the connecting rod 504 until the piston block 505 rises to the top of the slide cylinder 503. At this point, the ABS sheet is placed on the rotating shell 9. Due to the weight of the ABS sheet itself, it will first come into contact with multiple suction cups 405. The weight of the ABS sheet will press down on the suction cups 405, causing the connecting pipe 404 to slide downwards within the through hole 403. The connecting rod 504 at the bottom of the connecting pipe 404 will push the piston block 505 downwards within the slide cylinder 503. During the downward movement of the piston block 505, the hydraulic oil in the slide cylinder 503 will be squeezed back into the second manifold 501, and then flow back to the hydraulic oil tank 507 through the second hose 502. Since the ABS sheet is curved, the distance that the ABS sheet presses down on the suction cups 405 at different positions is also different. This allows each suction cup 405 to fully contact the lower surface of the ABS sheet, avoiding the problem that some suction cups 405 cannot effectively adhere due to the curvature of the ABS sheet.

[0041] After the ABS plate is placed, close the solenoid valve 506 to prevent the hydraulic oil in the slide 503 from flowing back into the hydraulic oil tank 507, thereby keeping the piston block 505 in a fixed position and ensuring that the suction cup 405 stably adsorbs the ABS plate. It should be noted that, since the ABS sheet has a certain weight and the hydraulic oil has a certain viscosity, when an external force presses on one or two suction cups 405, the remaining suction cups 405 will generate corresponding support force due to the incompressibility of the hydraulic oil, thereby maintaining the balance of the entire ABS sheet. Therefore, the ABS sheet will not tilt due to uneven force on a single suction cup.

[0042] It should be noted that the suction cup 405 is existing technology, and those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0043] Multiple protrusions 901 are welded to the upper surface of the rotating shell 9. The multiple protrusions 901 are located at the four edges of the ABS plate. The highest point of the protrusions 901 is lower than the upper surface of the ABS plate. The multiple protrusions 901 are used to limit the ABS plate and prevent the ABS plate from lateral displacement during rotation or testing, so as to ensure the accuracy of the testing position.

[0044] The working principle of this invention is as follows: First, the ABS plate to be tested is placed on the upper surface of the rotating shell 9 and between multiple protrusions 901. Since the ABS plate itself may be bent, the lower surface of the ABS plate will contact multiple suction cups 405. Under the action of gravity, the suction cups 405 are pressed down, which drives the connecting pipe 404 to slide down along the through hole 403. The connecting pipe 404 pushes the piston block 505 to move down in the slide cylinder 503 through the connecting rod 504. During the downward movement of the piston block 505, the hydraulic oil in the slide cylinder 503 will be squeezed back to the second manifold 501 and then flow back to the hydraulic oil tank 507 through the second hose 502. Since the degree of bending of the ABS plate is different, the distance that each suction cup 405 moves down under pressure is also different, so that each suction cup 405 can fit the lower surface of the ABS plate. Then, the solenoid valve 506 is closed to block the backflow of hydraulic oil and fix the position of the piston block 505. Subsequently, the external air extraction equipment is activated, and the first manifold 401 is evacuated through the first hose 402. The negative pressure is transmitted through the third hose 406 to each connecting pipe 404 and suction cup 405, so that the suction cup 405 firmly adheres to the ABS sheet. Next, the first linear motor 101 is started, which drives the second linear motor 102 to move along the length of the fixed frame 10. At the same time, the second linear motor 102 drives the fixed block 103, the distance sensor 104 at the bottom, the second roller 201, the swing frame 203, and the baffle 202 to move along the direction of the first linear motor 101. During this process, the second roller 201 first contacts the surface of the ABS plate, and after contact, it will be in an inclined state (see reference). Figure 3 As the first linear motor 101 continues to move, the second roller 201 rolls along the curved surface of the ABS plate. The change in the height of the ABS plate surface causes the swing frame 203 to swing adaptively around the rotating connection of the fixed block 103. The baffle 202, which is fixedly connected to the swing frame 203, also swings synchronously. At this time, the distance sensor 104 detects the change in distance between itself and the baffle 202 in real time. When it moves to the end, it continues to move, causing the second roller 201 to detach from the surface of the ABS plate. If a bend or bulge is found in the detected area, the ABS plate is a defective product. At this time, the detection is stopped, the ABS plate is removed, and then the ABS plate is recycled. Then, an undetected ABS plate is placed for detection. If no bending or protrusion is found in the inspected area, the second linear motor 102 is then started. The second linear motor 102 drives the fixed block 103 and related components to move a certain distance in a direction perpendicular to the first linear motor 101. Then the first linear motor 101 is started again, so that the second roller 201 re-contacts the ABS plate surface and performs the next bending test. This process is repeated until the entire surface of the ABS plate is inspected.

[0045] If no bends or protrusions are found, start the self-locking geared motor 302. The output shaft of the self-locking geared motor 302 drives the rotating housing 9 to rotate 90 degrees, causing the ABS sheet to rotate accordingly. Perform a comprehensive inspection of the ABS sheet in the same way in another direction to ensure that no potential bends are missed because the bending direction of the sheet is parallel to the initial inspection direction. After the inspection is completed, if no bends or protrusions are detected, the ABS sheet is a qualified product, and then the ABS sheet is removed.

[0046] As another embodiment of the detection component 1 of the present invention, refer to Figure 8 and Figure 9 The detection component 1 includes a fixed plate 107. A power component 6 is provided on one side of the fixed frame 10. The power component 6 is used to drive the fixed plate 107 to move. The power component 6 includes a third linear motor 601 fixed to one side of the fixed frame 10 by bolts. An L-shaped plate 603 is fixed to one side of the mover of the third linear motor 601 by bolts. A hydraulic cylinder 602 is fixed to the upper surface of the L-shaped plate 603 by bolts. The telescopic end of the hydraulic cylinder 602 passes through the L-shaped plate 603 and is fixed to the fixed plate 107. When the hydraulic cylinder 602 is started, it drives the fixed plate 107 to move downward. It should be noted that: the third linear motor 601 is existing technology, and the hydraulic cylinder 602 is an actuator in the hydraulic system. It achieves the telescopic function by cooperating with the hydraulic system, and achieves precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with magnetic switches, proximity switches or photoelectric switches. Those skilled in the art can set it according to actual needs, which will not be elaborated here. A mounting bracket 106 is bolted to the upper surface of the fixing plate 107. A dial indicator 105 is detachably connected to one side of the mounting bracket 106 by bolts. The detachable dial indicator 105 facilitates later maintenance and replacement. Two symmetrically arranged sliding rods 109 are slidably connected inside the fixing plate 107. The bottom ends of the two sliding rods 109 are bolted to a connecting bracket 110. A first roller 111 is rotatably connected between the inner walls of the two sides of the connecting bracket 110 by bearings. The lowest point of the first roller 111 protrudes from the connecting bracket 110. When the fixing plate 107 moves the sliding rods 109 and the connecting bracket 110 downwards, the first roller 111 will first contact the surface of the ABS plate. As the fixing plate 107 moves downwards, the first roller 111 will first contact the surface of the ABS plate. As the slide bar 109 continues to move downward, it slides upward within the fixed plate 107. The top of the connecting frame 110 contacts the probe of the dial indicator 105. Then, the dial indicator 105 is zeroed to ensure the accuracy of the initial detection state. When the third linear motor 601 drives the L-shaped plate 603 to move the hydraulic cylinder 602 and the fixed plate 107 as a whole, the first roller 111 rolls on the surface of the ABS plate. The bending of the ABS plate will cause the first roller 111 to move the connecting frame 110 and the slide bar 109 up and down, thereby pushing the probe of the dial indicator 105 to produce displacement. The change in the reading of the dial indicator 105 can intuitively reflect the height difference at different positions on the surface of the ABS plate, realizing the accurate measurement of the curvature. It should be noted that: In this application, dial gauge 105 is prior art. The dial gauge 105 can be model 32BFF12TM. Those skilled in the art can set it according to actual needs, which will not be elaborated here. The length of the first roller 111 is greater than the width of the ABS sheet, so that during the inspection process, the first roller 111 can completely cover the width direction of the ABS sheet. Therefore, the curvature detection of the entire width direction of the sheet can be completed by moving it once along the length direction of the ABS sheet.

[0047] Both ends of the slide rod 109 pass through the fixing plate 107, and a stop block 108 is welded to the top of the slide rod 109. The stop block 108 can prevent the slide rod 109 from slipping out of the fixing plate 107.

[0048] Working principle: When hydraulic cylinder 602 is activated, it moves fixed plate 107 downwards. As fixed plate 107 moves slide rod 109 and connecting frame 110 downwards, the first roller 111 contacts the ABS plate surface first. As fixed plate 107 continues to move downwards, slide rod 109 slides upwards within fixed plate 107. The top of connecting frame 110 contacts the probe of dial indicator 105. Then, dial indicator 105 is zeroed to ensure the accuracy of the initial detection state. When third linear motor 601 drives L-shaped plate 603 to move hydraulic cylinder 602 and fixed plate 107 as a whole, the first roller 111 rolls on the ABS plate surface. The bending of the ABS plate causes the first roller 111 to move connecting frame 110 and slide rod 109 up and down, thereby pushing dial indicator 105. The probe of 5 is displaced. After the test is completed, the hydraulic cylinder 602 is activated to move the fixed plate 107 upward, so that the first roller 111 is disengaged from the surface of the ABS plate. Then the external air extraction equipment is turned off, the suction cup 405 is released from adsorption and fixation of the ABS plate, the ABS plate is taken out, and then the solenoid valve 506 is opened. Due to gravity, the hydraulic oil in the hydraulic oil tank 507 can flow into the second manifold 501 through the second hose 502. The hydraulic oil in the second manifold 501 then flows into multiple slide cylinders 503 respectively. The hydraulic oil pushes the piston block 505 in the slide cylinder 503 to slide upward. The piston block 505 drives the connecting pipe 404 and the suction cup 405 to rise synchronously through the connecting rod 504 until the piston block 505 rises to the top of the slide cylinder 503, so as to prepare for the next test of the ABS plate.
