Description

Technical Field

[0001] The utility model relates to the technical field of automobile detection, in particular to a detection device for automobile seat bracket holes. Background Art

[0002] In the prior art, some hole structures are processed on the bracket of the automobile seat. After the bracket is processed on the assembly line, these hole positions need to be inspected to prevent sheet metal parts that do not meet the processing requirements from flowing out. For this purpose, the conventional inspection method is to insert a detection pin to determine whether the hole position is processed properly.

[0003] When the existing automobile seat bracket hole device detects the hole diameter, the detection pin is manually taken to detect the hole diameter on the automobile seat bracket.

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0043] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0045] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] Figure 1 FIG. 1 is a schematic diagram of the structure of a car seat bracket 100 provided in the prior art. Figure 1As shown, a plurality of holes are provided on the automobile seat bracket 100, wherein the connection hole 101 and the connection hole 2 102 need to be tested and qualified before subsequent assembly work can be performed. However, in the prior art, the test is performed by manually inserting a test pin into the connection hole 101 and the connection hole 2 102, and the need to manually test whether the hole to be tested is a through hole reduces the test efficiency. At the same time, since the position of the test pin can be flexibly changed when holding it, it is impossible to test whether the position between the adjacent connection holes 101 and 102 is accurate.

[0047] To this end, an embodiment of the utility model provides a vehicle seat bracket hole detection device, which can detect whether a hole is a through hole and at the same time detect the positional relationship between adjacent holes, thereby improving the efficiency of the vehicle seat bracket 100 detection.

[0048] like Figure 2-4 As shown, the automobile seat bracket hole detection device includes: a through hole detection mechanism 1 and a hole position detection mechanism 2, wherein the through hole detection mechanism 1 is used to detect whether the hole of the automobile seat bracket 100 is a through hole, and the hole position detection mechanism 21 is used to detect whether the position between adjacent openings 331 of the automobile seat bracket 100 is accurate.

[0049] Specifically, the through-hole detection mechanism 1 includes a first support frame 11, a feeding structure 4, a CCD camera 12 and a light source 13. The feeding structure 4 is fixedly connected to the first support frame 11. The feeding structure 4 is used to support and transport the car seat bracket 100 to be detected. The CCD camera 12 is arranged above the feeding structure 4, and the light source 13 is arranged below the feeding structure 4. The light source 13 is used to provide light for the car seat bracket hole. The CCD camera 12 is used to obtain a picture when light is irradiated on the car seat bracket hole. The CCD camera 12 and the light source 13 are arranged in a one-to-one correspondence. In this way, when the car seat bracket 100 is located at the feeding structure 4, the light source 13 located below directly irradiates the opening 331. The CCD camera 12 can take a picture of the opening 331 from above; the hole position detection mechanism 2 includes a hole position detection structure 21, a first lifting structure 22 and a support platform 23, the support platform 23 is used to support the car seat bracket 100, the first lifting structure 22 is fixedly connected to the support platform 23, the first lifting structure 22 is connected to the hole position detection structure 21 and can drive the hole position detection structure 21 to rise and fall, the hole position detection structure 21 can detect the hole position of the car seat bracket hole under the drive of the first lifting structure 22, the setting of the first lifting structure 22 can facilitate the feeding structure 4 to move the car seat bracket 100, and prevent the hole position detection structure 21 from interfering and causing the car seat bracket 100 to be unable to move normally.

[0050] The automobile seat support hole detection device provided by the utility model is respectively arranged above and below the automobile seat support 100 by a CCD camera 12 and a light source 13. The light source 13 directly irradiates the opening 331. If the opening 331 is a through hole, the light source 13 passes through the hole. If the opening 331 is not a through hole, the light source 13 cannot pass through the hole. In this way, when the CCD camera 12 takes a photo, it can be compared with the pre-stored picture to determine whether the opening 331 is a through hole. Compared with the prior art, it is not necessary to manually detect the holes one by one, thereby improving the detection efficiency. In addition, since the hole position detection mechanism 2 is fixed to the support platform 23 by the first lifting structure 22, the position of the hole position detection mechanism 2 is fixed relative to the automobile seat support 100. Compared with the prior art, the hole position detection mechanism 2 with a fixed position can check the hole position of the hole of the automobile seat support 100.

[0051] It should be noted that it is a prior art to determine whether the opening 331 is a through hole by comparing the photo taken by the CCD camera 12 with the pre-stored picture, which will not be described in detail here.

[0052] In some embodiments, Figure 1 and Figure 4 As shown, the automobile seat bracket hole detection device also includes an oil spraying mechanism 3. After the hole detection of the automobile seat bracket 100 is completed and the automobile seat bracket 100 is qualified, lubricating oil needs to be sprayed at the connection hole 101 and the connection hole 2 102 to prevent the automobile seat bracket 100 from rusting. Specifically, the oil spraying mechanism 3 is arranged downstream of the hole position detection mechanism 2, and the oil spraying mechanism 3 includes a second support frame 31, an oil source, a nozzle 32 and a residual oil receiving platform 33. The second support frame 31 is fixedly provided with the nozzle 32 and the residual oil receiving platform 33. The residual oil receiving platform 33 is arranged below the nozzle 32, and the automobile seat bracket 100 is placed between the residual oil receiving platform 33 and the nozzle 32. The nozzle 32 is connected to the oil source for spraying lubricating oil. After the lubricating oil is sprayed to the hole of the car seat bracket 100, the excess lubricating oil will drip from the car seat bracket 100 to the excess oil receiving platform 33. The excess lubricating oil is collected from the excess oil receiving platform 33 and then removed from the excess oil receiving platform 33. In this way, the collected excess lubricating oil can be reused to prevent waste. At the same time, it can also prevent the lubricating oil from dripping onto the ground and causing dirt on the ground.

[0053] In some embodiments, the residual oil receiving platform 33 has an opening, and the area of ​​the opening of the residual oil receiving platform 33 decreases gradually from top to bottom in the vertical direction. It can be understood that the opening of the residual oil receiving platform 33 is trumpet-shaped, and the cross-sectional area of ​​the opening is not limited to a circle, and can also be a rectangle, as long as the lubricating oil can be guided. The lubricating oil will be guided from top to bottom by the opening under the influence of gravity, and an opening 331 is provided at the bottom of the opening, and then the oil flows out from the opening 331. The setting of the opening facilitates the collection of the lubricating oil.

[0054] In some embodiments, the oil injection mechanism 3 further includes an oil recovery tank 34, and the oil port of the oil recovery tank 34 is connected to the opening 331 of the residual oil receiving platform 33 through a pipeline. The oil recovery tank 34 is connected to the opening 331 through a pipeline, and the lubricating oil directly flows into the oil recovery tank 34, which is convenient for collection. The setting of the oil recovery tank 34 can prevent the lubricating oil from dripping from the opening 331 to the ground, and at the same time can ensure that the lubricating oil will not be contaminated after being collected, so that the purpose of reuse can be achieved.

[0055] In some embodiments, Figure 5 As shown, the automobile seat bracket hole detection device also includes a feeding structure 4. The first support frame 11 and the support platform 23 are both provided with a feeding structure 4. The feeding structure 4 is used to support and transport the automobile seat bracket 100. The setting of the feeding structure 4 can realize the automatic transportation of the automobile seat bracket 100. In this way, the feeding structure 4 cooperates with the through-hole detection mechanism 1 and the hole position detection mechanism 2 to achieve the purpose of automatic detection of the automobile seat bracket 100. For example, after the automobile seat bracket 100 is transported to the through-hole detection mechanism 1 by the feeding structure 4, it is first detected whether the opening 331 is a through hole. If the detection is qualified, the feeding structure 4 works to move the automobile seat bracket 100 to the hole position detection mechanism 2 for hole position detection. This saves the time of manual transportation of the automobile seat bracket 100 and improves the detection efficiency.

[0056] For example, the feeding structure 4 includes an electric roller 41 and a mounting frame 42, and the electric roller 41 can be rotatably arranged on the mounting frame 42; the feeding structure 4 is respectively arranged at the first support frame 11 and the support platform 23, and the mounting frame 42 is respectively fixedly connected to the first support frame 11 and the support platform 23, and the mounting frame 42 fixedly connected to the first support frame 11 is arranged between the CCD camera 12 and the light source 13, so that the light emitted by the light source 13 directly irradiates the car seat bracket 100, and the CCD camera 12 can directly photograph the connection hole 101 and the connection hole 2 102 at the car seat bracket 100. When the car seat bracket 100 is located directly above the electric roller 41, the electric roller 41 works to drive the car seat bracket 100 to move to the position and then stop. The specific structure of the electric roller 41 is the existing technology and will not be described in detail here.

[0057] Of course, in some other embodiments, the feeding structure 4 includes a mounting frame 42 and a pulley structure, and the pulley structure can be rotatably arranged on the mounting frame 42. The feeding structure 4 is respectively arranged at the first support frame 11 and the support platform 23, and the mounting frame 42 is respectively fixedly connected to the first support frame 11 and the support platform 23, and the mounting frame 42 fixedly connected to the first support frame 11 is arranged between the CCD camera 12 and the light source 13, so that the light emitted by the light source 13 directly irradiates the car seat bracket 100, and the CCD camera 12 can directly capture the connection hole 101 and the connection hole 2 102 at the car seat bracket 100. The pulley structure is used to drive the car seat bracket 100 to move to the position to be detected. The specific structure of the pulley structure is the prior art and will not be described in detail here.

[0058] like Figure 6 As shown, the hole position detection mechanism 2 also includes a second lifting structure 24 and a positioning structure 25. The feeding structure 4 and the positioning structure 25 are both arranged on the top of the support platform 23. The second lifting structure 24 is fixedly connected to the support platform 23. The feeding structure 4 is connected to the second lifting structure 24 and can be lifted and lowered under the drive of the second lifting structure 24. The positioning structure 25 can pass through the positioning hole 103 and the positioning hole 2 104 at both ends of the car seat bracket 100 to position the car seat bracket 100; the first lifting structure 22 is connected to the hole position detection structure 21 and can drive the hole position detection structure 21 to rise and fall. The hole position detection structure 21 includes a detection lifting structure 211, a detection pin 212 and a detection sensor 213. The detection lifting structure 211 is connected to the detection pin 212 and can drive the detection pin 212 to rise and fall. The detection pin 212 can move vertically relative to the detection sensor 213 according to the state of the hole to be detected.

[0059] During inspection, the car seat bracket 100 to be inspected is located on the feeding structure 4, and the second lifting structure 24 drives the feeding structure 4 to descend. After the car seat bracket 100 to be inspected is positioned by the positioning structure 25, the hole position detection structure 21 moves down to the position of the car seat bracket 100 through the first lifting structure 22, and the detection pin 212 descends to the hole to be inspected through the detection lifting structure 211. Since the position of the detection pin 212 is fixed, the detection pin 212 can detect whether the hole to be inspected is a through hole, and can also determine whether the hole position is accurate. In addition, when the hole to be inspected needs to be determined whether a nut is welded, the position of the detection pin 212 can be determined by detecting the detection sensor 213, and then various detection needs can be met through the hole position detection structure 21.

[0060] In some embodiments, Figure 7 , Figure 8 and Fig. 9As shown, the hole position detection structure 21 also includes a limit detection member 214, a support block 215 and a recovery member 216. The limit detection member 214 and the recovery member 216 are respectively arranged below and above the support block 215. A plurality of detection sensors 213 are fixed to the support block 215 in order from top to bottom. The limit detection member 214 is fixedly arranged on the upper part of the detection pin 212, and the recovery member 216 is arranged on the lower part of the detection pin 212. The limit detection member 214 cooperates with the detection sensor 213 to determine the position of the detection pin 212, and the recovery member 216 can restore the detection pin 212 to its initial position. For example, the detection sensor 213 is a photoelectric sensor or an infrared sensor that is integrated with a transmitter and a receiver. In the vertical direction, the support block 215 is provided with more than two detection sensors 213, and each detection sensor 213 has a different height.

[0061] The position between connection hole 101 and connection hole 2 102 is fixed. In order to detect whether the distance between the two meets the requirements, in this embodiment, the detection mechanism corresponding to connection hole 101 and connection hole 2 102 has two detection pins 212, and the positions of the two detection pins 212 are arranged according to the corresponding positions of connection hole 101 and connection hole 2 102.

[0062] Take the detection mechanism detecting the connection hole 101 and the connection hole 2 102 at the same time, and the support block 215 is provided with three detection sensors 213 of different heights as an example. When the position of the hole to be detected is accurate, the detection pin 212 falls into the hole to be detected, and the limit detection member 214 is located at the detection sensor 213 at the bottom, and the detection sensor 213 at the bottom sends a detection signal. At this time, the car seat bracket 100 is qualified; when either the connection hole 101 or the connection hole 2 102 is not a through hole, the limit detection member 214 is located at the detection sensor 213 at the middle height, and the detection sensor 213 at the middle height sends a detection signal, reporting that the car seat bracket 100 is unqualified; when the hole to be detected is provided with a nut, the inaccurate position of the nut will cause the detection pin 212 to move upward, so that the detection sensor 213 at the top sends a detection signal, reporting that the car seat bracket 100 is unqualified, and the recovery member 216 is compressed. After the detection, the recovery member 216 drives the detection pin 212 to return to the initial position under the action of its own restoring force. A limit block is set at the bottom of the detection pin 212. For example, the recovery member 216 is a spring, and the spring is sleeved on the outer periphery of the detection pin 212. One end of the spring contacts the bottom of the support block 215, and the other end of the spring contacts the limit block. The support block 215 and the limit block cooperate to prevent the spring and the detection pin 212 from detaching.

[0063] For example, the position limit detection member 214 has a plurality of shielding pieces 2141, and the number of the shielding pieces 2141 is the same as the number of the corresponding detection sensors 213. The shielding pieces 2141 can shield the receiving end and the transmitting end of the corresponding detection sensor 213.

[0064] In some embodiments, Figure 7 As shown, the hole position detection structure 21 also includes a third support frame 217 and a support plate 218. The support plate 218 is fixedly connected to the support platform 23 for supporting the first lifting structure 22. The first lifting structure 22 is fixedly arranged on the top of the support plate 218. The first lifting structure 22 is fixedly connected to the third support frame 217 and can drive the third support frame 217 to rise and fall. The third support frame 217 is provided with multiple hole position detection structures 21 at intervals for supporting multiple hole position detection structures 21. The multiple hole position detection structures 21 are arranged one-to-one with the multiple holes to be detected. The holes to be detected are not limited to the connection hole 101 and the connection hole 2 102. When the holes on the automobile seat bracket 100 need to be detected, they can be detected by the hole position detection structure 21. The multiple hole position detection structures 21 are lifted and lowered by the first lifting structure 22, and different holes to be detected can be detected at the same time, thereby improving the detection efficiency, reducing the time consumed by the detection, and realizing automatic detection.

[0065] In some embodiments, Figure 7 As shown, the hole position detection structure 21 further includes a slide rail 219 and a slider 2110, the slide rail 219 is slidably connected to the slider 2110, the slide rail 219 is fixedly arranged on the side wall of the support plate 218 facing the hole position detection structure 21, the length direction of the slide rail 219 extends in the vertical direction, and the slider 2110 is fixedly connected to the third support frame 217. When the first lifting structure 22 lifts the third support frame 217, the third support frame 217 will shake when it moves, and the slide rail 219 and the slider 2110 can provide guidance for the support frame when it is lifted and lowered, so that the third support frame 217 can move stably.

[0066] In some embodiments, Figure 6 and Figure 7 As shown, the hole position detection structure 21 also includes a limiting structure 2111, which is arranged on the side wall of the support plate 218 facing the hole position detection structure 21. The limiting structure 2111 is used to limit the rising height of the third support frame 217 to prevent the third support frame 217 from rising too high. For example, the limiting structure 2111 can be a limit switch.

[0067] like Fig.10As shown, in some embodiments, the positioning structure includes a support seat 251, a positioning pin 252 and a third lifting structure 253, the positioning pin 252 is fixedly connected to the third lifting structure 253, the third lifting structure 253 is fixedly connected to the support seat 251, the support seat 251 is fixedly arranged on the top of the support platform 23, and the positioning pin 252 can be respectively inserted into the positioning hole 103 and the positioning hole 2 104 of the car seat bracket 100. When the height of the car seat bracket 100 is lowered by the second lifting structure 24, the positioning pin 252 rises under the drive of the third lifting structure 253, and the positioning pin 252 passes through the positioning hole of the car seat bracket 100 to realize the positioning of the car seat bracket 100, so as to avoid the position of the car seat bracket 100 from moving during detection. Since the positioning hole 103 and the positioning hole 2 104 have different shapes, the top shapes of different positioning pins 252 are also different. For example, the positioning hole 103 is a circular hole and the positioning hole 2 104 is a waist hole. Then, the top shape of the positioning pin 252 corresponding to the positioning hole 103 is circular, while the top shape of the positioning pin 252 corresponding to the positioning hole 2 104 is diamond-shaped.

[0068] Furthermore, in order to compress the automobile seat support 100 to prevent movement during detection, the automobile seat support hole detection device further includes a plurality of clamping structures 5, which are respectively arranged at both ends of the support platform 23, and the clamping structures 5 are arranged one by one in correspondence with the four corners of the automobile seat support 100. When the automobile seat support 100 is moved into place, the clamping structure 5 clamps the automobile seat support 100 from the four corners of the automobile seat support 100. The specific structure of the clamping structure 5 is the prior art and will not be described in detail again.

[0069] Continue to refer Figure 6 In some embodiments, the automobile seat support hole detection device further includes a waste receiving device 6 and a waste pushing device 7. The waste receiving device 6 and the hole detection structure 21 are arranged on both sides of the support platform 23, and the waste pushing device 7 is arranged on both sides of the support plate 218. The waste pushing device 7 can push the waste to move to the waste receiving device 6, and the waste receiving device 6 is used to receive and place the waste. When the automobile seat support 100 fails the inspection, the waste pushing device 7 moves the automobile seat support 100 to the waste receiving device 6 to ensure the normal operation of the subsequent automobile seat support 100 inspection, and prevent the unloading waiting caused by the unqualified inspection from delaying the subsequent automobile seat support 100 inspection.

[0070] In some embodiments, the waste receiving device 6 includes a waste receiving frame 61 and a fourth lifting structure 62, the fourth lifting structure 62 is arranged on the side wall of the support platform 23, the waste receiving frame 61 is arranged on the top of the support platform 23, the waste receiving frame 61 has a plurality of receiving grids 611, each receiving grid 611 is used to place a car seat bracket 100, and the fourth lifting structure 62 is fixedly connected to the waste receiving frame 61 to promote the lifting of the waste receiving frame 61. The setting of multiple receiving grids 611 can ensure that multiple unqualified car seat brackets 100 are accommodated and placed, thereby improving the detection efficiency. For example, after the receiving grid 611 located at the top receives the car seat bracket 100, the fourth lifting structure 62 drives the car seat bracket 100 to rise so that the receiving grid 611 below is aligned with the car seat bracket 100 to be detected. Of course, it can also be that after the receiving grid 611 located at the bottom receives the car seat bracket 100, the fourth lifting structure 62 drives the car seat bracket 100 to descend so that the receiving grid 611 located at the top is aligned with the car seat bracket 100 to be detected. This ensures that all unqualified automobile seat brackets 100 can be pushed into the receiving grid 611 .

[0071] In addition, in order to ensure smooth lifting and lowering of the waste receiving rack 61, the waste receiving device also includes a guide column 63 and a guide sleeve. One end of the guide column 63 passes through the guide sleeve and is fixedly connected to the waste receiving rack 61, and the guide sleeve is connected to the top of the support platform 23. Part of the guide column 63 is located below the top surface of the support platform 23.

[0072] In some embodiments, Figure 7 As shown, the waste pushing device 7 includes a horizontal moving structure 71 and a pushing frame 72, the cylinder body of the horizontal moving structure 71 is fixedly connected to the third support frame 217, and the cylinder rod of the horizontal moving structure 71 is fixedly connected to the pushing frame 72. After the car seat bracket 100 is detected as unqualified, the horizontal moving structure 71 drives the pushing frame 72 to push the car seat bracket 100 into the receiving grid 611, and then the horizontal moving structure 71 drives the pushing frame 72 to return to the initial position and wait for the next action.
