Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically to an electric air vent rotation angle detection device. Background Technology

[0002] With the rapid development of new energy vehicles, auto parts are moving towards intelligentization. The most obvious example is the car's air conditioning system. Nowadays, electric air vents, which replace traditional air vents, are directly controlled by the vehicle's infotainment system, thereby achieving dynamic airflow management and avoiding discomfort caused by direct airflow to passengers. In order to accurately control the direction of airflow, it is necessary to test the accuracy of the rotation angle of the electric air vents during the production process.

[0003] Electric air vents used in new energy vehicles often require installation near the driver and passenger doors, necessitating the bypass of steering columns and dashboard supports. This necessitates an angled, curved, or tilted design. During vehicle assembly, the center console installation requires the prior installation of related components, necessitating the packaging of different shaped electric air vents belonging to the same center console according to a configuration list for assembly. Therefore, during production, both types of electric air vents need to be tested simultaneously. Existing testing equipment places the air vent on a matching fixed template, inserts a plug into the vent's drive motor to rotate the guide vanes, and then measures the rotation angle of the vanes. However, because the template shapes and fixed positions differ for different vent shapes, the equipment can only continuously measure one type of vent. When producing both types simultaneously, measurements must be taken in batches and on different dates, impacting production testing and shipping efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an electric air vent rotation angle detection device to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric air vent rotation angle detection device, comprising a frame, and further comprising:

[0006] The frame is equipped with a detection position, which includes a base plate fixedly connected to the frame. A lifting device is fixedly connected to the bottom surface of the base plate, and a guide mechanism is fixedly connected to the top surface of the lifting device. A backing mechanism is provided on the base plate, and a workpiece is placed on the guide mechanism. The guide mechanism positions and fixes the workpiece during its downward movement, and the backing mechanism backs and fixes the workpiece after the guide mechanism has moved downward. The detection position also includes a shifting mechanism and multiple laser emitters. The shifting mechanism drives the laser emitters to move, and the guide mechanism includes a support frame fixedly connected to the top of the lifting device.

[0008] Preferably, the guiding mechanism includes two columns fixedly connected to the top surface of the substrate. The columns are L-shaped. A rotating push rod is rotatably mounted on the vertical part of the column via a torsion spring. Locking grooves extending to the sides of the rotating push rod are opened on the opposite sides of the two columns. A locking crossbar is slidably connected between the two locking grooves. A trigger switch is fixed on the top surface of the horizontal part of the column.

[0009] Preferably, a fixed clamping block is fixedly connected inside the support frame, a movable clamping block is slidably connected inside the support frame, a guide block is fixedly connected to the top surface of the substrate, and during the downward movement of the support frame, the movable clamping block moves toward the fixed clamping block after contacting the guide block, and a reset spring is provided inside the support frame to make the movable clamping block move away from the fixed clamping block.

[0010] Preferably, the two ends of the locking crossbar are slidably connected to sliding columns, which are pushed outward by springs. When the locking crossbar is at the top of the locking groove, the rotating push rod cannot rotate. The side of the support frame facing the locking crossbar is hinged to an actuating frame, which is driven by a torsion spring and keeps horizontal with the bottom surface of the support frame. When the actuating frame contacts the locking crossbar, it drives the locking crossbar to move within the locking groove.

[0011] Preferably, the substrate has a straight groove, and the abutting mechanism includes linear motors located on both sides of the straight groove. A movable base is fixedly connected to the slider of the linear motor. A central shaft is rotatably mounted inside the movable base. A first template is fixedly sleeved on the central shaft. A second template is slidably connected to one side of the first template. A guide groove is formed on the top surface of the movable base. The bottom end of the central shaft passes through the straight groove and is fixedly sleeved with a first gear. A first rack is slidably connected to the bottom surface of the substrate. The first rack is driven by a cylinder to move in a direction relative to the first gear. A sliding column with one end located in the guide groove is fixed on the inner side of the second template. When the central shaft rotates to bring the second template closer to the workpiece, the second template slides outward.

[0012] Preferably, the workpiece is divided into two types: a straight air vent and an oblique air vent. The air duct of the straight air vent is straight, and the air duct of the oblique air vent is zigzag. Both the straight air vent and the oblique air vent include a housing, a lower motor, and a side motor. The lower motor is located directly below the housing during the workpiece detection process.

[0013] Preferably, the displacement mechanism includes a first cylinder located on the front side of the workpiece and a second cylinder located on the rear side of the workpiece.

[0014] Preferably, when the first cylinder and the second cylinder are not extended, the laser emitter is in the first position; when the telescopic ends of the first cylinder and the second cylinder are extended, the laser emitter is in the second position. The side of the second mounting bracket is provided with a guide groove so that the corresponding laser emitter can adjust the angle toward the workpiece during movement.

[0015] Preferably, the pressing mechanism includes a pressing cylinder fixedly connected to the top surface of the substrate, a rotating arm hinged to the top of the cylinder body, and a pressing block slidably connected to the end of the rotating arm away from the pressing cylinder.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Please see Figures 1 to 15 The electric air vent rotation angle detection device provided in this embodiment of the invention includes a frame 1, and further includes:

[0037] The frame 1 is provided with a detection position 2. The detection position 2 includes a base plate 21 fixedly connected to the frame 1. A lifting device 212 is fixedly connected to the bottom surface of the base plate 21. A guide mechanism 22 is fixedly connected to the top surface of the lifting device 212. A backing mechanism 23 is provided on the base plate 21. A workpiece 24 is placed on the guide mechanism 22. The guide mechanism 22 positions and fixes the workpiece 24 during the downward movement. The backing mechanism 23 backs and fixes the workpiece 24 after the guide mechanism 22 has moved down. The detection position 2 also includes a shifting mechanism 26 and multiple laser emitters 25. The shifting mechanism 26 drives the laser emitters 25 to move. The guide mechanism 22 includes a support frame 226 fixedly connected to the top of the lifting device 212.

[0038] The substrate 21 is also provided with a pressing mechanism 27 adjacent to the workpiece 24. The pressing mechanism 27 is used to press the workpiece 24 downward. The substrate 21 is provided with a plurality of data plugs 28.

[0039] In this invention, after the workpiece 24 is placed in the support frame 226 by the guide mechanism 22, during the downward movement of the support frame 226, the guide mechanism 22 will first push the workpiece towards the abutment mechanism 23 until one side of the workpiece 24 abuts against the inner side of the support frame 226. As the support frame 226 continues to move downward, the clamping block inside the support frame 226 will clamp the workpiece from the bottom, thus preventing the workpiece from moving horizontally. Then, the abutment mechanism 23 is driven to move towards the workpiece 24 and abut against the workpiece 24 from one side to prevent the shell of the workpiece 24 from being deformed and damaged due to unilateral force when the data plug 28 is inserted into the workpiece 24. Then, the pressing mechanism 27 is used to press down the workpiece 24, preventing the workpiece 24 from moving up and down, thereby fixing the workpiece 24 on the detection position 2. Then, by reading the data of the laser emitter 25, it can be known whether the rotation angle of the internal guide vanes of the workpiece 24 meets the requirements after being driven. As the workpiece 24 moves downward with the support frame 226, due to the different shapes of the workpiece 24, when the workpiece 24 activates the trigger switch 225, the abutment mechanism 23 works to align the abutment mold that matches the shape of the workpiece 24 with the workpiece. At the same time, the shifting mechanism 26 drives the laser emitter 25 to move to the position set by the corresponding configuration. Thus, during the inspection process, two types of electric air vents in the same set can be clamped and tested without changing the fixture. This allows electric air vents of different shapes to be alternately processed without stopping the machine to change the fixture, which is convenient for small-batch, rapid production, improves delivery efficiency, and enhances the adaptability of production to market fluctuations.

[0040] In an embodiment of the present invention, the guide mechanism 22 includes two columns 221 fixedly connected to the top surface of the substrate 21. The columns 221 are L-shaped. A rotating push rod 222 is rotatably mounted on the vertical part of the columns 221 by a torsion spring. Locking grooves 223 extending to the side of the rotating push rod 222 are provided on the opposite sides of the two columns 221. A locking crossbar 224 is slidably connected between the two locking grooves 223. A trigger switch 225 is fixed on the top surface of the horizontal part of the columns 221.

[0041] Depend on Figures 2 to 7 It can be seen that the rotating push rod 222 will rotate around its mounting point, thus presenting a certain angle with the column 221 without external interference. When the inclined air outlet 24B is placed on the bearing frame 226, as the rotating push rod 222 is unlocked, it gradually rotates outward, thereby causing the rotating push rod 222 to push the inclined air outlet 24B towards the abutment mechanism 23.

[0042] In an embodiment of the present invention, a fixed clamping block is fixedly connected inside the support frame 226, and a movable clamping block 227 is slidably connected inside the support frame 226. A guide block 228 is fixedly connected to the top surface of the substrate 21. During the downward movement of the support frame 226, the movable clamping block 227 moves toward the fixed clamping block after contacting the guide block 228. A reset spring is provided inside the support frame 226 to keep the movable clamping block 227 away from the fixed clamping block. The top surface of the guide block 228 is an inclined surface.

[0043] Although the outer shells 241 of different electric air vents vary in shape according to production needs, the motor assemblies used as driving components are usually purchased from the same supplier. That is, the motors of different electric air vents are the same. Therefore, only the motor of the workpiece 24 needs to be positioned to position the entire workpiece 24. When the fixed clamping block and the movable clamping block 227 position and fix the motor from both sides, the entire workpiece 24 is also positioned. Thus, even if the outer shells 241 of the workpiece 24 are different, as long as the shape of its motor assembly is the same, the same set of fixed clamping blocks and movable clamping blocks 227 can be used. This allows the device to position, clamp, and test workpieces 24 with different outer shells 241, improving the versatility of the equipment and reducing the management cost of the template.

[0044] In an embodiment of the present invention, sliding columns are slidably connected to both ends of the locking crossbar 224. The sliding columns are pushed outward by springs. When the locking crossbar 224 is located at the top of the locking groove 223, the rotating push rod 222 cannot rotate. A toggle frame 229 is hinged to the side of the support frame 226 facing the locking crossbar 224. The toggle frame 229 is driven by a torsion spring and keeps horizontal with the bottom surface of the support frame 226. During the process of contacting the locking crossbar 224, the toggle frame 229 drives the locking crossbar 224 to move within the locking groove 223.

[0045] Depend on Figures 5 to 8 It can be seen that after the support frame 226 moves downward and the actuating frame 229 begins to contact the locking crossbar 224, as the support frame 226 continues to move downward, the locking crossbar 224 is pushed downward. At this time, the sliding pins at both ends of the locking crossbar 224 slide inward, causing the sliding pins at both ends of the locking crossbar 224 to gradually separate from the rotating push rod 222. At this time, the rotating push rod 222 rotates outward under the torsion spring connected to it, thereby contacting the air inlet end of the workpiece 24 and pushing the workpiece 24 away from the column 221 until the bottom side of the workpiece 24 contacts the support frame 226. As the locking crossbar 224 reaches the locking groove 223, the pushing resistance of the locking crossbar 224 increases, exceeding the torque provided by the torsion spring connected to the actuating frame 229, causing the actuating frame 229 to rotate around its hinge axis with the support frame 226, thereby causing the actuating frame 229 to no longer contact the support frame 226. The support frame 226 contacts the workpiece 24. After the workpiece 24 is measured, as the support frame 226 moves upward, the workpiece 24 pushes the rotating push rod 222 back into the column 221. When the actuating frame 229 contacts the locking crossbar 224, it pushes it upward, thereby inserting it into the side of the rotating push rod 222. At this time, the outward rotation of the rotating push rod 222 cooperates with the locking groove 223 on the side of the column 221 to clamp the inserted part of the locking crossbar 224, thereby locking the rotating push rod 222 and preventing it from rotating. This allows the rotating push rod 222 to push and position the workpiece 24 as it moves downward with the support frame 226, and to return to the column 221 to reset when the workpiece 24 leaves. This ensures that the rotating push rod 222 can be used continuously to push the workpiece 24 placed on the support frame 226 to ensure accurate positioning.

[0046] In an embodiment of the present invention, a straight groove 211 is provided on the substrate 21, and the abutting mechanism 23 includes a linear motor 238 located on both sides of the straight groove 211. A movable base 231 is fixedly connected to the slider of the linear motor 238. A central shaft 232 is rotatably mounted in the movable base 231. A first template 233 is fixedly sleeved on the central shaft 232. A second template 234 is slidably connected to one side of the first template 233. A guide groove 237 is provided on the top surface of the movable base 231. The bottom end of the central shaft 232 passes through the straight groove 211 and is fixedly sleeved with a first gear 235. A first rack 236 is slidably connected to the bottom surface of the substrate 21. The first rack 236 is driven by a cylinder to move in a direction relative to the first gear 235. A sliding column with one end located in the guide groove 237 is fixed on the inner side of the second template 234. When the central shaft 232 rotates to make the second template 234 approach the workpiece 24, the second template 234 slides outward.

[0047] Depend on Figures 2 to 6As can be seen, the first template 233 moves along with the movable base 231. Before the movable base 231 moves, the support frame 226 has already been moved to the lowest position by the lifting device 212. As the movable base 231 is driven to move towards the workpiece 24, the activation state of the trigger switch 225 determines whether the first rack 236 is close to the first gear 235. When the trigger switch 225 is not activated, the first rack 236 is pushed outward by the slide cylinder connected to it. At this time, when the first gear 235 moves with the movable base 231, it will drive the central shaft 232 to rotate through meshing with the first rack 236. At this time, the first template 233... During rotation, the second template 234 moves away from the workpiece 24 and faces the workpiece 24, so that when the moving base 231 approaches the inclined air vent 24B, the second template 234 abuts against the workpiece 24. When the trigger switch 225 is activated by contacting the straight air vent 24A, the first rack 236 is pulled back by the connected slide cylinder, so that the first gear 235 does not contact the first rack 236 during the movement. At this time, the first template 233 still faces the straight air vent 24A, thus abutting against the straight air vent 24A. By placing different workpieces, different configurations are automatically switched to abut against workpieces 24 of different shapes, making the use of the equipment more convenient.

[0048] In an embodiment of the present invention, the workpiece 24 is divided into two types: a straight air vent 24A and an oblique air vent 24B. The air duct of the straight air vent 24A is straight, and the air duct of the oblique air vent 24B is zigzag. Both the straight air vent 24A and the oblique air vent 24B include a housing 241, a lower motor 242 and a side motor 243. The lower motor 242 is located directly below the housing 241 during the detection of the workpiece 24. During the detection, the data plug 28 is inserted into the sockets of the lower motor 242 and the side motor 243.

[0049] Depend on Figure 13 and Figure 14 It is known that the length, width, and height of the straight air vent 24A and the oblique air vent 24B are different, and the orientation angle of the air inlet end covered with polyurethane foam is also different. However, the shape and interface orientation of the lower motor 242 are the same. Thus, only the lower motor 242 needs to be positioned to position the entire workpiece 24, so that the data plug 28 driven by the slide cylinder can be accurately inserted into the motor interface. Since the air inlet end of the oblique air vent 24B will be tilted when placed on the guide mechanism 22, it will not activate the trigger switch 225. Therefore, the position of the relevant mechanism can be changed according to the activation or non-activation of the trigger switch 225, so that the equipment can use the corresponding configuration according to the actual shape of the workpiece 24. Thus, the present invention can clamp two air vents of the same shape in the same set according to the configuration without changing the abutment mold and clamping mold, which improves the flexibility of the inspection process and facilitates small-batch and rapid production.

[0050] In an embodiment of the present invention, the shifting mechanism 26 includes a first cylinder 261 located on the front side of the workpiece 24 and a second cylinder 263 located on the rear side of the workpiece 24. A first mounting bracket 262 is fixedly connected to the telescopic end of the first cylinder 261. A second mounting bracket 264 is fixedly connected to the top of the cylinder body of the second cylinder 263. A first slide 265 is fixedly connected to the telescopic end of the second cylinder 263. A connecting plate 266 is slidably connected to the side of the second mounting bracket 264. A sliding sleeve 267 is slidably connected to the first slide 265. The outer side of the sliding sleeve 267 is fixedly... A connecting rod is fixedly connected, with one end of the connecting rod rotatably mounted on the side of the connecting plate 266. The laser emitter 25 is fixedly connected to the side of the first mounting bracket 262 and the second mounting bracket 264. When the first cylinder 261 and the second cylinder 263 are not extended, the laser emitter 25 is in the first position. When the telescopic ends of the first cylinder 261 and the second cylinder 263 are extended, the laser emitter 25 is in the second position. The side of the second mounting bracket 264 is provided with a guide groove so that the corresponding laser emitter 25 can adjust the angle toward the workpiece 24 during the movement.

[0051] from Figures 11 to 15 It is known that the air inlets and outlets of workpieces 24 of different shapes have slightly different orientations. This makes it impossible to fix the laser emitter 25 and test both the straight air inlet 24A and the angled air inlet 24B. However, by making the laser emitter 25 movable, the device can adjust the laser orientation of the laser emitter 25 according to the activation state of the trigger switch 225 and the preset movement parameters. This allows the same set of laser emitters 25 to be used to test different workpieces 24, making the device more flexible in use.

[0052] In an embodiment of the present invention, the pressing mechanism 27 includes a pressing cylinder 271 fixedly connected to the top surface of the substrate 21. A rotating arm 272 is hinged to the top of the cylinder body of the pressing cylinder 271. A pressing block 273 is slidably connected to one end of the rotating arm 272 away from the pressing cylinder 271. The pressing block 273 is pushed away from the rotating arm 272 by a spring located on the bottom surface of the rotating arm 272.

[0053] like Figure 12 As shown, after the extension end of the pressing cylinder 271 extends, the rotating arm 272 will rotate from a vertical state to a horizontal state. At this time, the pressing block 273 will adhere to the top surface of the workpiece 24, thereby pressing down on the workpiece 24. At this time, the workpiece 24 is fixed in both the vertical and horizontal directions, so that when the drive motor rotates later, the position of the workpiece 24 is fixed and does not move, ensuring the accuracy of the data measured by the laser emitter 25.

[0054] In an embodiment of the present invention, a display 3 and a printer 4 are provided inside the rack 1, and the printer 4 is used to print detection information.

[0055] Working principle:

[0056] When testing different types of workpieces 24, the workpiece 24 is first placed bottom-down on the support frame 226, ensuring that the lower motor 242 is located inside the support frame 226 and between the movable clamping block 227 and the fixed clamping block (at this time, the movable clamping block 227 is pushed away from the fixed clamping block by the spring connected to it, so that there is a gap between the two that is greater than the width of the lower motor 242, which facilitates the placement of the workpiece 24). Then, the lifting device 212 is driven to work, causing it to move the support frame 226 downward. As the support frame 226 moves downward, the locking bar 224 is pushed downward, causing the rotating push rod 222 to rotate and contact the workpiece 24. Under the push of the rotating push rod 222, the side of the lower motor 242 at the bottom of the workpiece 24 will contact the inner side of the support frame 226, which ensures the stability of the workpiece 24 during the downward movement and also allows the rotating push rod 222 to perform the first positioning of the workpiece 24.

[0057] As the support frame 226 continues to move downward, when the movable clamping block 227 contacts the guide block 228, the movable clamping block 227 moves towards the fixed clamping block. After contacting the lower motor 242 of the workpiece 24, it pushes the entire workpiece 24 to move. Then, as the support frame 226 moves to the bottom, the movable clamping block 227 cooperates with the fixed clamping block to fix the workpiece 24 in the horizontal direction. At this time, the workpiece 24 can only move upward. Then, by activating the pressing mechanism 27, the workpiece 24 can be fixed on the support frame 226.

[0058] Then, the abutment mechanism 23 is controlled to move closer to the workpiece 24, thereby abutting the workpiece 24 and improving the stability of the workpiece 24 when the data plug 28 is inserted into the lower motor 242 and the side motor 243.

[0059] Subsequently, during the inspection process, two sets (four in total) of laser emitters 25 located before and after workpiece 24 are activated. At this time, one laser emitter 25 in the same set is aligned with the closed state of the corresponding guide vane, and the other laser emitter 25 in the same set is aligned with the fully open state of the guide vane. Then, the guide vane is rotated to the maximum angle by the lower motor 242 and the side motor 243. When the laser emitter 25 in the fully open state cannot receive a reflected signal, it means that the guide vane of workpiece 24 cannot be fully opened, and at this time it can be determined that there is a problem with workpiece 24.

[0060] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
