Description

Technical Field

[0001] The present invention relates to the technical field of automobile production detection devices, and particularly to an inspection device for mushroom buckles of automobile sunroof frames and its working method. Background Art

[0002] A sunroof glass is installed on the top of an automobile, and the sunroof glass of the automobile can play a role in ventilation and air exchange. Currently, the fixation of the automobile sunroof glass generally adopts a mushroom buckle connection structure, and the mushroom buckle can bond the sunroof frame and the roof body together.

[0003] The existing detection methods for mushroom buckles of automobile sunroof frames mainly include photoelectric sensors and proximity switches. The existing two mainstream sensors can only detect whether the mushroom buckle exists. Among them, the photoelectric sensor determines whether the mushroom buckle exists according to the detected distance; among them, the proximity switch checks whether the mushroom buckle exists according to whether the sunroof frame triggers the proximity switch. The existing detection device cannot detect the thickness of the mushroom buckle, resulting in the mushroom buckle can only be manually detected, which will reduce the detection efficiency and increase the labor intensity of workers. Therefore, the existing detection device cannot achieve automatic detection in the link of mushroom buckle detection, resulting in the difficulty of improving the overall production efficiency of the automobile sunroof.

[0004] In addition, the existing detection device is fixed on a certain plane, such as the ground, the desktop or the tooling tabletop. Therefore, the position of the detection unit in the detection device is in a fixed state. Since the mushroom buckle is installed in the sunroof frame of the automobile, when the curvature of the sunroof frame itself or the height of the sunroof frame changes, it will cause the detection unit to misdetect the thickness of the mushroom buckle. For example, when the curvature of the sunroof frame bulges downward or the distance from the sunroof frame to the detection unit is low, it will cause the mushroom buckle to be in a lower position, which will cause the detection unit to detect that the thickness of the mushroom buckle is too large. Similarly, when the curvature of the sunroof frame bulges upward or the height distance of the sunroof frame is high, it will cause the mushroom buckle to be in a higher position, resulting in the detection unit detecting that the thickness of the mushroom buckle is small. Therefore, the existing detection device cannot adjust the position of the detection unit according to the curvature of the sunroof frame or the height of the sunroof frame, resulting in errors in the detection of the mushroom buckle. Summary of the Invention

[0005] An advantage of the present invention is to provide an inspection device for mushroom buckles of automobile sunroof frames.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0034] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "a" should not be construed as limiting the quantity.

[0035] Reference Figures 1 to 7 , the mushroom snap detection device for the automotive sunroof frame according to a preferred embodiment of the present invention will be elaborated in detail below. The mushroom snap detection device for the automotive sunroof frame can detect mushroom snaps of different thicknesses, avoid the problems of manual detection of mushroom snaps, and improve the detection efficiency.

[0036] The mushroom snap detection device for the automotive sunroof frame includes a base 10, at least one reference member 20, a detection member 30, and at least two detection units 40.

[0037] The reference member 20 is disposed on the top of the base 10, and a relief space 201 is formed on the top of the base 10 so that when the skylight frame fits against the reference member 20, the mushroom buckle enters the relief space 201.

[0038] The detection member 30 is movably disposed on the base 10. The detection member 30 includes a pressure-receiving portion 311 and at least one detected portion 312. The pressure-receiving portion 311 is at least partially located in the relief space 201. And when the pressure-receiving portion 311 is pushed by the mushroom buckle, the pressure-receiving portion 311 and the detected portion 312 move relative to the base 10 synchronously.

[0039] At least two detection units 40 are disposed on the base 10. At least two detection units 40 form at least two detection spaces corresponding to the detected portions 312. When the detected portions 312 move relative to the base 10, the detected portions 312 trigger the two detection units 40 in sequence.

[0040] Specifically, for the convenience of description, here one detected portion 312 and two detection units 40 are described, but the number of the detection units 40 is not limited to two. When detecting the thickness of the mushroom buckle, the skylight frame contacts the reference member 20, the mushroom buckle enters the relief space 201, and presses the pressure-receiving portion 311, so that the detected portion 312 moves relative to the base 10, thereby triggering the detection unit 40. Further specifically, when the detected thickness of the mushroom buckle is relatively thin, the distance that the mushroom buckle pushes the pressure-receiving portion 311 and the detected portion 312 to move is relatively small. Therefore, the thickness of this mushroom buckle can only trigger one detection unit 40. When the detected thickness of the mushroom buckle is relatively thick, the distance that the mushroom buckle pushes the pressure-receiving portion 311 and the detected portion 312 to move is relatively large. Therefore, the mushroom buckle can push the detected portion 312 to trigger the two detection units 40. Therefore, the number of the triggered detection units 40 is proportional to the thickness of the mushroom buckle. Furthermore, the thickness of the mushroom buckle can be known according to the number of the triggered detection units 40, achieving the purpose of detecting mushroom buckles with different thicknesses.

[0041] The base 10 is provided with a through hole 101.

[0042] The detection member 30 further includes a detection rod 31 and a reset member 32. The detection rod 31 penetrates through the through hole 101. The upper end portion of the detection rod 31 forms the pressure-receiving portion 311, and the lower end portion of the detection rod 31 forms the detected portion 312. The reset member 32 is elastically connected to the detection rod 31 and the base 10, so that after the detection rod 31 moves downward, the reset member 32 can return the detection rod 31 to its initial position, which is beneficial for the detection rod 31 to quickly return to its initial position after detection, and facilitates the subsequent multiple detections of the thickness of the mushroom buckle by the detection device.

[0043] Specifically, the reset member 32 is implemented as a reset spring, and the through hole 101 is implemented as a stepped hole. The detection rod 31 can completely penetrate through the through hole 101, while the reset spring can only pass through the upper half of the stepped hole, so that the reset spring is embedded in the upper half of the stepped hole. The detection rod 31 is fixedly inserted into the reset spring. Therefore, when the pressure-receiving portion 311 of the detection rod 31 is squeezed by the mushroom buckle and the detection rod 31 moves relative to the base 10, the reset spring will be squeezed, and when the mushroom buckle is removed, the reset spring will return the detection rod 31 to its initial position, playing a role in resetting the detection rod 31.

[0044] The detection unit 40 can be implemented as a proximity switch sensor or a micro switch. The detected portion 312 is implemented as a trigger wheel. The trigger wheel is arranged on the detection rod 31, and the number of trigger wheels corresponds to the number of proximity switch sensors. At least two proximity switch sensors are arranged on the base 10 in the vertical direction. Here, two proximity switch sensors and two trigger wheels are taken as examples for description. According to Figure 2 the view, the upper trigger wheel corresponds to the upper proximity switch sensor, and the lower trigger wheel corresponds to the lower proximity switch sensor. When the thickness of the mushroom buckle is relatively thin, when the detection member 30 is squeezed downward by the mushroom buckle, only one trigger wheel enters the detection space of the proximity switch. At this time, only one proximity switch sensor is triggered. When the thickness of the mushroom buckle is relatively thick, both proximity switch sensors detect the corresponding trigger wheels. Further specifically, the distance from the upper trigger wheel to the upper proximity switch sensor is equal to the thickness of the relatively thin mushroom buckle, and the distance from the lower trigger wheel to the lower proximity switch sensor is equal to the thickness of the relatively thick mushroom buckle, so that the number of proximity switch sensors triggered can reflect the thickness of the mushroom buckle.

[0045] By using the proximity switch sensor or microswitch, only when there is a substantial displacement will the proximity switch or microswitch be triggered, which can reduce the probability of false triggering compared with the photoelectric sensor and ensure the accuracy of the mushroom buckle during detection.

[0046] The base 10 includes a fixed seat 11 and a floating frame 12. The floating frame 12 is movably arranged on the fixed seat 11 along the moving direction of the detection rod 31. The reference member 20 is arranged on the top of the floating frame 12. The detection rod 31 is movably arranged on the top of the floating frame 12. The detection unit 40 is arranged on the floating frame 12.

[0047] Specifically, in accordance with Figure 2 As shown, the detection rod 31 is vertically movably arranged on the fixed seat 11. Correspondingly, the floating frame 12 is also vertically movably arranged on the fixed seat 11. The floating frame 12 can float relative to the fixed seat 11 in the vertical direction. Correspondingly, the detection rod 31 and the detection unit 40 arranged on the floating frame 12 can both float relative to the fixed seat 11. When the downward arc of the skylight frame itself is too large, the skylight frame will squeeze the reference member 20 downward. The reference member 20 can move downward by means of the floating frame 12, so as to avoid excessive downward movement of the detection rod 31, and further avoid the detection unit 40 detecting that the thickness of the mushroom buckle is too large. Therefore, the floating frame 12 can compensate for the error brought by the skylight frame to the mushroom buckle, thereby improving the accuracy of the mushroom buckle during detection.

[0048] The base 10 further includes an elastic member 13. The elastic member 13 is elastically connected between the floating frame 12 and the fixed seat 11, so that when the floating frame 12 is subjected to a downward pressure, it can move relative to the fixed seat 11. And when the external pressure disappears, the floating frame 12 returns to its original position. And the elastic member 13 can also ensure that the reference member 20 on the top of the floating frame 12 is always in contact with the skylight frame, thereby more accurately detecting the thickness of the mushroom buckle.

[0049] Specifically, the elastic member 13 includes a guide post 131 and a spring 132. The guide post 131 is fixedly arranged on the floating frame 12 or the fixed seat 11. A mating hole 102 adapted to the guide post 131 is formed on the fixed seat 11 or the floating frame 12. The guide post 131 is inserted into the mating hole 102. The spring 132 is sleeved on the guide post 131, and the outer diameter of the spring 132 is larger than the outer diameter of the mating hole 102. By using the cooperation of the guide post 131 and the spring 132, the floating frame 12 can move more accurately during the movement process, and avoid errors in detection caused by the deviation of the floating frame 112.

[0050] Further specifically, the guiding column 131 is fixedly arranged on the floating frame 12. The fixing seat 11 is provided with the mating hole 102. The guiding column 131 is inserted into the mating hole 102. The spring 132 is sleeved on the guiding column 131 and located outside the mating hole 102, ensuring that the spring 132 is located between the fixing seat 11 and the floating frame 12. When the floating frame 12 moves downward, the spring 132 is compressed. When the floating frame 12 stops moving downward, the spring 132 pushes the floating frame 12 upward to restore its original position.

[0051] The guiding column 131 includes a screw 1311, a column body 1312 and a blocking portion 1313. The screw 1311 is fixedly connected to the top of the column body 1312 and the floating frame 12. The blocking portion 1313 is arranged at the bottom of the column body 1312. The inside of the mating hole 102 is also stepped, so that the blocking portion 1313 can partially pass through the mating hole 102. During installation, first insert the top end of the column body 1312 into the mating hole 102 from bottom to top, and pass through the spring 132. Then fix the top of the column body 1312 to the floating frame 12 through the screw 1311. Since the blocking portion 1313 can only partially pass through the mating hole 102, the guiding column 131 connects the floating frame 12 and the fixing seat 11.

[0052] The base 10 further includes an adjusting member 14. The adjusting member 14 is arranged on the floating frame 12. The detecting unit 40 is arranged on the adjusting member 14, so that the detecting unit 40 can adjust its position on the floating frame 12 along the moving direction of the detecting rod 31. Adjusting the position of the detecting unit 40 on the floating frame 12 can enable the detecting unit 40 to detect mushroom snap fasteners with different thicknesses.

[0053] Such as Figure 4 、 Figure 5As shown. The adjustment member 14 includes a bent rod 141 and at least four fasteners 142. Wherein, the bent rod 141 is provided with an adjustment groove 1401 along the moving direction of the detection rod 31. The detection unit 40 penetrates through the adjustment groove 1401, and one detection unit 40 is detachably fixed to the adjustment groove 1401 by two of the fasteners 142. When it is necessary to adjust the position of the detection unit 40 on the bent rod 141, the fastener 142 is used to loosen the detection unit 40, so that the detection unit 40 can slide inside the adjustment groove 1401. After the position of the detection unit 40 is adjusted in place, the detection unit 40 is fixed to the bent rod 141 by the fastener 142, completing the adjustment of the position of the detection unit 40.

[0054] Specifically, the fastener 142 is implemented as a nut. The outer wall of the detection unit 40 is provided with threads adapted to the nut. Two of the nuts are sleeved on one detection unit 40. After the detection unit 40 penetrates through the adjustment groove 1401, one or two of the nuts are twisted to make the two nuts approach each other, and the detection unit 40 is clamped between the bent rod 141 by the two nuts, thereby realizing the fixation of the detection unit 40. When it is necessary to disassemble the detection unit 40 for movement, one or two of the nuts are loosened, so that the detection unit 40 can slide inside the adjustment groove 1401, achieving the purpose of adjusting the position of the detection unit 40. In addition, each detection unit 40 is cooperated with two of the fasteners 142, so that the position of each detection unit 40 on the bent rod 141 can be adjusted, and further enabling the detection unit 40 to detect mushroom snap fasteners of different thicknesses.

[0055] More specifically, the bent rod 141 is composed of a horizontal portion 1411 and a vertical portion 1412 that are perpendicularly connected to each other. The horizontal portion 1411 is disposed on the floating frame 12, the vertical portion 1412 is disposed on the horizontal portion 1411, and the adjustment groove 1401 is opened on the vertical portion 1412. The two fasteners 142 cooperate to detachably fix the detection unit 40 to the vertical portion 1412. By using the horizontal portion 1411 and the vertical portion 1412, the distance between the detection unit 40 and one end of the floating frame 12 is made, which is convenient for disassembling and assembling the detection unit 40, and the vertical portion 1412 makes the detection space formed by the detection unit 40 located on the moving path of the detected portion 312.

[0056] The reference member 20 is detachably connected to the floating frame 112 by the bolt. The bolt passes through the reference member 20 and is threadedly connected to the floating frame 12. By using the bolt, the reference member 20 can be stably fixed to the floating frame 112, and the reference member 20 can be disassembled when it is necessary to disassemble the reference member 20. Specifically, the number of the reference members 20 can be implemented as two, and the two reference members 20 are correspondingly arranged on the left and right sides of the top of the floating frame 12. With the support of the two reference members 20, the reference member 20 can form the avoidance space 201 at the top of the floating frame 12, and the top of the reference member 20 is spherical. When a skylight frame is placed on the top of the reference member 20, the spherical reference member 20 contacts the skylight frame with a small contact area, ensuring that the reference member 20 stably supports the skylight frame. In addition, the contact surface between the skylight frame and the reference member 20 is a curved surface or an inclined surface, and the contact area between the reference member 20 and the skylight frame is small, avoiding the contact between the protruding part of the skylight frame and the reference member 20, and ensuring that the thickness of the mushroom buckle can be accurately detected.

[0057] As Figure 6 , Figure 7 shows a schematic diagram of the detection device for detecting mushroom buckles with different thicknesses. In the figure, the reference numeral 300 is the skylight frame, the reference numeral 200 is the mushroom buckle, and Figure 6 the thickness of the mushroom buckle 200 in Figure 7 is relatively thin, and when the frame 300 is placed on the top of the support member 12, the mushroom buckle 200 only triggers one proximity switch sensor, where Figure 7 the thickness of the mushroom buckle 200 in

[0058] is relatively thick, and

[0059] both of the two proximity switch sensors in

[0060] are triggered.

[0061] Step S3, judging the thickness of the mushroom buckle according to the number of the detection units 40 triggered by the detected part 312.

[0062] When the mushroom buckle pushes the detected part 312 to move, the detected part 312 enters the detection area of the detection unit 40, thereby triggering the detection unit 40. When the thickness of the mushroom buckle is relatively thin, the moving distance of the detected part 312 pushed is relatively small, and the number of detection units 40 triggered by the detected part 312 is relatively small. When the thickness of the mushroom buckle is relatively thick, the moving distance of the detected part 312 pushed is relatively large, and the number of detection units triggered by the detected part 312 is relatively large. Therefore, the thickness of the mushroom buckle can be judged according to the number of detection units 40 triggered, achieving the purpose of detecting mushroom buckles with different thicknesses.

[0063] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the principle, any deformation or modification can be made to the embodiments of the present invention.
