Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of exhaust hood detection, in particular to a rotary detection carrier and an automatic detection device comprising the same. Background Art
[0002] An airbag assembly generally includes an energy cover, an exhaust hood, an initiating material, a nitrogen generator and an airbag. The energy cover is located in the middle of the exhaust hood. The initiating material is placed in the energy cover. The nitrogen generator is placed between the energy cover and the exhaust hood. The airbag is located outside the exhaust hood. During operation, an initiating device provided on the airbag assembly ignites the initiating material, which diffuses outwards through a week of holes evenly distributed on the energy cover and reacts with the nitrogen generator placed in the exhaust hood to rapidly generate gas. The gas is exhausted outwards through the exhaust holes evenly distributed on the side wall of the exhaust hood, so that the airbag expands rapidly to achieve the purpose of protecting the vehicle occupants.
[0003] The new type of airbag exhaust hood is formed by stamping stainless steel material. However, due to defects such as high yield point, high hardness, significant cold work hardening effect and easy occurrence of cracks in the stainless steel material, defects such as surface scratches on the exhaust hood, burrs on the side wall, leakage of side punching holes and incomplete flange edges occasionally occur during the stamping process. Assembling defective parts into an airbag assembly and installing it on a vehicle poses a major safety hazard. Therefore, it is necessary to detect all parts of the surface of the exhaust hood before leaving the factory.
[0004] The detection of the exhaust hood includes many aspects, such as surface condition, the size and position of the mounting holes on the flange, and the size and position of the side exhaust holes, etc. Usually, a high-speed camera is used to take pictures to detect whether it is qualified. Since the positional relationship between the exhaust hood and the high-speed camera needs to be adjusted for different detection items, different detection items are usually completed at different workstations. The existing technical solutions for multi-station detection mainly include two types: manipulator transfer and turntable transfer. Among them, manipulator transfer uses a manipulator to transfer products between various workstations, which requires the manipulator to move frequently, inadvertently lengthening the entire detection process time, shortening the service life of the manipulator, and large space occupation of the equipment. The turntable transfer can place the product on a carrier to complete the entire detection process, which requires the clamping of the product by the carrier to be universal for different detection processes and requires firm clamping. However, in the prior art, the fixation of the product on the carrier is often achieved by lateral clamping. Since the outer surface of the exhaust hood is the detection surface, clamping from the outside will interfere with the detection result of the photographing, and the periphery of the exhaust hood is a relatively thin flange, which is not convenient for stable clamping. Therefore, at present, only manual or manipulator frequent transfer and frequent fixation methods can be used for the detection of the exhaust hood, resulting in low detection efficiency.
[0005] Therefore, it is necessary to design a rotary detection carrier with high detection accuracy and high efficiency and an automatic detection device comprising the same. Summary of the Utility Model
[0006] In order to solve the technical problem that the carrier structure in the existing automated detection equipment is not applicable to the detection of exhaust hoods and cannot stably fix the exhaust hood, resulting in the use of detection equipment with relatively low efficiency for exhaust hood detection, the present utility model provides a rotary detection carrier and an automatic detection equipment including the same to solve the above problems.
[0007] The present utility model proposes a rotary detection carrier, including a rotary positioning plate, a product positioning block, a rotary shaft and a limiting block. The exhaust hood is placed on the rotary positioning plate. The product positioning block is located inside the exhaust hood and is connected with an elastic positioning component that abuts against the inner surface of the exhaust hood. The bottom of the rotary shaft has an anti-rotation block that cooperates with the output shaft of the rotary motor. The rotary motor drives the rotary shaft, the rotary positioning plate and the product positioning block to rotate synchronously. The rotary shaft is rotatably connected to the workbench of the detection equipment and can be lifted relative to the workbench. The limiting block is installed on the rotary shaft and is located below the workbench.
[0008] Further, the product positioning block has an annular retaining wall arranged parallel to the side wall of the exhaust hood. A plurality of elastic positioning components are arranged circumferentially along the annular retaining wall. Each elastic positioning component includes a bushing threadedly connected to the annular retaining wall, a telescopic spring and a steel ball located inside the bushing. One end of the bushing facing the exhaust hood has a receiving groove for receiving the telescopic spring and the steel ball, and the steel ball abuts against the surface of the exhaust hood.
[0009] Further, the elastic positioning component further includes a nut threadedly connected to the bushing, and the nut abuts against the inner surface of the annular retaining wall.
[0010] Further, a rotary base is fixed to the top of the workbench. A sleeve is sleeved outside the rotary shaft. The sleeve is connected to the rotary base through a bearing. When the rotary shaft is jacked up, the limiting block abuts against the sleeve.
[0011] Further, the height where the elastic positioning component is located is lower than the height of the exhaust holes on the exhaust hood.
[0012] Further, the rotary positioning plate respectively has limiting grooves that cooperate with the ends of the rotary shaft and the product positioning block.
[0013] Further, a reset pin is installed at the end of the rotary base. A reset hole is provided on the rotary positioning plate. When the rotary positioning plate is placed on the top of the sleeve, the reset pin can be inserted into the reset hole.
[0014] The present utility model also proposes an automatic detection equipment, including a workbench, a plurality of detection stations and the above-mentioned rotary detection carrier. The workbench can rotate around the center and make the rotary detection carrier reach each detection station.
[0015] Further, the multiple detection stations include an exhaust hole detection station, where a lifting platform and a rotating motor located at the top of the lifting platform are provided. The top of the rotating motor has a rotation stopping groove engaged with a rotation stopping block.
[0016] Further, a fixed seat is provided at the center of the workbench, and a high-speed camera for detecting the exhaust hood at the exhaust hole detection station is installed on the fixed seat. When the rotating shaft is lifted, the lens of the high-speed camera is directly facing the exhaust hole of the exhaust hood.
[0017] The beneficial effects of the present utility model are as follows:
[0018] (1) In the present utility model, the rotating detection carrier for placing the exhaust hood is rotatably connected to the workbench, and at the same time, the exhaust hood is fixed by using the elastic positioning component, so that the rotating detection carrier can rise and rotate when detecting the exhaust holes of the exhaust hood, thereby completing the detection of all exhaust holes at one station, and the exhaust hood can be stably clamped to ensure the detection accuracy.
[0019] (2) In the present utility model, the elastic positioning component adopts a structure combining a telescopic spring and steel balls. The telescopic spring ensures the pressing force and also facilitates the loading of the exhaust hood, and the steel balls can reduce the damage of the elastic positioning component to the surface of the exhaust hood.
[0020] (3) The present utility model uses a rotating workbench to move the exhaust hood installed on the rotating detection carrier to different stations, without the need to frequently clamp the exhaust hood, improving the detection efficiency. Description of the Drawings

Specific Embodiment
[0030] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0031] Embodiment 1
[0032] As Figure 2 、 Figure 3As shown in the figure, a rotation detection vehicle includes a rotation positioning plate 1, a product positioning block 2, a rotation shaft 3, and a limit block 4. The rotation shaft 3 serves as the rotation center of the rotation detection vehicle 9 and is used to connect the rotation motor 24 on one of the fixed workstations of the detection device and other rotating components of the rotation detection vehicle 9. The rotation positioning plate 1 and the product positioning block 2 are used to mount the exhaust hood 5. The exhaust hood 5 is placed on the rotation positioning plate 1. The product positioning block 2 is located inside the exhaust hood 5 and is connected with an elastic positioning component 6 that abuts against the inner surface of the exhaust hood 5. The product positioning block 2, the rotation positioning plate 1, and the rotation shaft 3 are fixed in sequence. The elastic positioning component 6 refers to an elastic pressure component, and the existence of its elastic force can ensure the pressing effect and facilitate the installation of the exhaust hood 5 at the same time. The bottom of the rotation shaft 3 has an anti-rotation block 7 that cooperates with the output shaft of the rotation motor 24. The rotation motor 24 drives the rotation shaft 3, the rotation positioning plate 1, and the product positioning block 2 to rotate synchronously. The rotation shaft 3 is rotatably connected to the workbench 8 of the detection device and can move up and down relative to the workbench 8. The limit block 4 is installed on the rotation shaft 3 and is located below the workbench 8. The limit block 4 is used to limit the height to which the rotation shaft 3 is lifted. The lowest position of the rotation shaft 3 is the position when the rotation positioning plate 1 is placed on the workbench 8.
[0033] As Figure 1 Shown in the figure is the structure of the exhaust hood 5. The exhaust hood 5 includes an annular cover 501 and a flange 502 located at the open end of the annular cover 501. Exhaust holes 503 are evenly distributed on the side wall of the annular cover 501, and mounting holes 504 are provided on the flange 502.
[0034] In the present utility model, a plurality of elastic positioning components 6 press the annular cover 501 from the inside of the exhaust hood 5, and the elastic preloading of the elastic positioning components 6 is used to ensure the pressing effect. There are no clamping components outside the exhaust hood 5, so it will not affect the detection outside the exhaust hood 5. At the same time, the setting of the rotation shaft 3 enables the rotation detection vehicle 9 to move up and down and rotate relative to the workbench 8. When the exhaust hood 5 does not need to be rotated, the rotation detection vehicle 9 is stably placed on the workbench 8. When it is necessary to rotate the exhaust hood 5 to detect the exhaust holes 503 in the circumferential direction, the rotation shaft 3 is lifted to separate the rotation positioning plate 1 from the workbench 8 to avoid friction during rotation.
[0035] Product positioning block 2:
[0036] The product positioning block 2 has an annular retaining wall 201 arranged parallel to the side wall of the exhaust hood 5. A plurality of elastic positioning components 6 are arranged along the circumference of the annular retaining wall 201. Each elastic positioning component 6 includes a bushing 601 threadedly connected to the annular retaining wall 201, a telescopic spring 602, and a steel ball 603 located inside the bushing 601. One end of the bushing 601 facing the exhaust hood 5 has a receiving groove 6011 for receiving the telescopic spring 602 and the steel ball 603, and the steel ball 603 abuts against the surface of the exhaust hood 5. As Figure 4As shown, the annular retaining wall 201 is provided with threaded holes corresponding to the elastic positioning assembly 6, and the outer surface of the bushing 601 is provided with external threads. The bushing 601 is fixed on the fixing hole of the annular retaining wall 201. The distance between the bushing 601 and the inner wall of the annular cover 501 is controlled by adjusting the depth of the screw. One end of the steel ball 603 abuts against the annular cover 501, and the other end abuts against the telescopic spring 602. When the exhaust hood 5 is installed on the outside of the product positioning block 2 from top to bottom, the steel ball 603 rolls and rubs against the inner wall of the exhaust hood 5, thereby reducing and avoiding the wear of the inner wall of the annular cover 501. A retracted slope surface is set at the outlet of the receiving groove 6011, and the slope surface can inhibit the steel ball 603 from falling, but the steel ball 603 can partially extend out of the receiving groove 6011 and abut against the annular cover 501. The product positioning block 2 is also provided with a bottom plate 202 for fixing with the rotating positioning plate 1.
[0037] In a further design, in order to improve the fixing effect between the bushing 601 and the annular retaining wall 201 and avoid thread failure, the elastic positioning assembly 6 also includes a nut 604 threadedly connected to the bushing 601 , and the nut 604 abuts against the inner surface of the annular retaining wall 201 .
[0038] The elastic positioning component 6 can abut against any position on the annular cover 501, preferably evenly abutting along the circumferential direction or axially symmetrically abutting. In terms of height setting, since the detection of the exhaust hole 503 is photographed by a high-speed camera 22, if there is a structure passing through the exhaust hole 503 inside, it will interfere with the detection structure. Therefore, it is preferred that the height of the elastic positioning component 6 is lower than the height of the exhaust hole 503 on the exhaust hood 5.
[0039] Connection between the rotating shaft 3 and the workbench 8:
[0040] The rotating shaft 3 and the workbench 8 not only need to rotate relative to each other but also need to be able to move axially, so a transfer structure needs to be set. In this embodiment, a rotating base 10 is fixed on the top of the workbench 8, and a sleeve 11 is provided on the outer sleeve of the rotating shaft 3. The rotating shaft 3 and the sleeve 11 are clearance-matched, and the rotating shaft 3 can move up and down relative to the sleeve 11. At the same time, the sleeve 11 has a center positioning function for the rotating shaft 3, and the rotating shaft 3 will not shake. The sleeve 11 is connected to the rotating base 10 through a bearing 12. When the rotating shaft 3 is lifted up, the limit block 4 abuts against the sleeve 11. The setting of the rotating base 10 enables the bearing 12 to be installed on the rotating base 10, so that there is no need to improve the structure of the workbench 8, and the rotating base 10 has a small structure, and the replacement cost after damage is low. The axial positioning of the sleeve 11 and the rotating base 10 is achieved by a shoulder 1101 located at one end of the sleeve 11 and a retaining spring 13 located at the other end of the sleeve 11.
[0041] like Figure 2 and Figure 6As shown, the rotating base 10 is fixed to the workbench 8 by screws. Two bearings 12 are installed inside the rotating base 10. The top of the bushing 11 has a shoulder 1101, which abuts against the end face of the upper bearing 12. A groove 1102 for installing a snap ring 13 is provided in the middle of the bushing 11, and the snap ring 13 abuts against the end face of the lower bearing 12. When the rotating shaft 3 is not jacked up, the rotating positioning plate 1 is placed on the top of the bushing 11.
[0042] The rotating positioning plate 1 preferably also has limiting grooves 101 that cooperate with the end of the rotating shaft 3 and the product positioning block 2 respectively, as Figure 3 and Figure 5 shown. The limiting groove 101 at the bottom of the rotating positioning plate 1 cooperates with the end face of the rotating shaft 3, and the limiting groove 101 at the top of the rotating positioning plate 1 cooperates with the bottom end face of the product positioning block 2. The design of the limiting groove 101 is both for convenient and quick positioning and installation, and can also improve the connection stability of the three.
[0043] Embodiment Two
[0044] On the basis of Embodiment One, a pressing block 14 is also fixed on the bottom plate 202 of the product positioning block 2. The setting of the pressing block 14 is to increase the overall weight of the rotating structure, so that when the rotating shaft 3 is not jacked up, the rotating positioning plate 1 can be stably placed on the workbench 8 under the pressure of the pressing block 14.
[0045] Embodiment Three
[0046] In the above embodiments, as Figure 3 shown, a return pin 15 is installed at the end of the rotating base 10, and a return hole 102 is provided on the rotating positioning plate 1. When the rotating positioning plate 1 is placed on the top of the bushing 11, the return pin 15 can be inserted into the return hole 102. Only one return pin 15 and one return hole 102 are provided. When detecting the exhaust hole 503, it is necessary to rotate the exhaust hood 5, but it is not certain whether the detection is complete. The setting of the return pin 15 and the return hole 102 can ensure complete detection, that is, only when the rotating positioning plate 1 is jacked up and rotates an integer number of circumferences can the return pin 15 and the return hole 102 be docked again.
[0047] Embodiment Four
[0048] An automatic detection device, as Figure 7 shown, includes a workbench 8, a plurality of detection stations, and the rotating detection carrier 9 for the automotive airbag exhaust hood 5 described above. The workbench 8 can rotate around the center and make the rotating detection carrier 9 reach each detection station.
[0049] The inspection stations are set according to inspection requirements. In this embodiment, they include a loading station 17, an exhaust hole inspection station 18, a mounting hole inspection station 19, a surface inspection station 20, and a discharging station 21. One or more rotating inspection carriers 9 can be provided. In this embodiment, multiple rotating inspection carriers 9 are provided to improve the inspection efficiency. Among them, the loading station 17 transfers the products on the loading conveyor belt to the rotating inspection carrier 9. The mounting hole inspection station 19 uses a high-speed camera 22 to take pictures of the mounting holes 504 on the flange 502 from top to bottom, and transmits the data to the inspection and analysis software equipped with the device for analysis and comparison to identify whether the size and position of the mounting holes 504 are correct ( Figure 7 The high-speed camera at the mounting hole inspection station 19 is not shown). The surface inspection station 20 uses a high-speed camera 22 to take pictures of the surface of the exhaust hood 5 from top to bottom and transmits the data to the inspection and analysis software equipped with the device to identify defects such as scratches and dents on the surface of the exhaust hood 5. The discharging station 21 sorts the products according to the inspection results. The exhaust hole inspection station 18 linearly photographs the exhaust holes 503 of the exhaust hood 5 using a high-speed camera 22 and transmits the data to the inspection software equipped with the device to compare whether there are defects such as leak holes and misaligned hole positions. Using the combination of a high-speed camera 22 and inspection software to inspect the product surface is prior art. The present utility model does not improve the principle of this part, but only improves the structure of the carrier. Therefore, the present utility model will not describe the inspection principle of the high-speed camera 22 in detail.
[0050] The driving structure for driving the lifting and rotation of the rotating inspection carrier 9 in the present utility model is provided at the exhaust hole inspection station 18, that is, located Figure 7 below the workbench 8 in Figure 2 as shown. A lifting table 23 and a rotating motor 24 located at the top of the lifting table 23 are provided below the rotating shaft 3. The top of the rotating motor 24 has a rotation stop groove 25 that engages with the rotation stop block 7.
[0051] The cross-section of the rotation stop block 7 is non-circular. When the rotation stop block 7 and the rotation stop groove 25 cooperate, the rotating motor 24 can drive the rotating shaft 3 to rotate.
[0052] At other stations, the high-speed camera 22 can be installed above the corresponding station. At the exhaust hole inspection station 18, the high-speed camera 22 is located on the side of the exhaust hood 5. In order to reduce the size of the device, in a preferred embodiment, a fixed seat 16 is provided at the center of the workbench 8, and the workbench 8 rotates around the fixed seat 16. The high-speed camera 22 at this station is installed on the fixed seat 16.
[0053] The utility model has the following effects: (1) It can detect defects such as surface bruises of the exhaust hood 5, burrs on the side wall of the machine shell, leakage holes in side punching, incomplete flange edges, and long blanking burrs, meeting the "0" defect requirement of automotive parts and ensuring product quality.
