Description

Technical Field

[0001] This utility model relates to the field of product testing and conveying technology, and in particular to a conveying device for testing automotive HUD products. Background Technology

[0002] HUD is an automotive component, and in many inspection processes, it often involves the transport of workpieces.

[0003] A search revealed a prior art electrical performance testing device for automotive HUD motherboards (Announcement No.: CN217879306U), comprising a machine base and a controller. The machine base is equipped with a product transfer line and a conductive mechanism. The product transfer line is connected to the conductive mechanism and is used to transport HUD motherboards. The conductive mechanism is used to electrically connect the HUD motherboards on the product transfer line to the controller. The product transfer line includes a loading transfer line, an unloading transfer line, and a transfer transfer line. The loading transfer line and the unloading transfer line are parallel to each other. The transfer transfer line is connected to the unloading end of the loading transfer line and the loading end of the unloading transfer line, respectively. The transfer transfer line is used to transport the HUD motherboards from the loading transfer line to the unloading transfer line.

[0004] Existing technologies often employ gear / belt drives, which make it difficult to control repeatability errors. Furthermore, direct contact motion is prone to vibration, leading to misalignment between the HUD and the windshield simulator, thus affecting the accuracy of optical testing. There is room for optimization in the existing workpiece conveying methods.

[0005] Therefore, we propose a conveying device for testing automotive HUD products. Utility Model Content

[0006] The present invention mainly solves the technical problem of vibration affecting the detection accuracy during the above-mentioned conveying process, and provides a conveying device for testing automotive HUD products.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a conveying device for testing automotive HUD products, comprising:

[0008] A guide rail, wherein several stators are fixedly mounted on the top of the guide rail;

[0009] A slide structure is set above the guide rail for load-bearing. The slide structure includes a mover, a coil, and a Hall sensor. The coil and the Hall sensor are fixedly installed at the bottom of the mover, and the coil is located directly above the stator.

[0010] A clamping assembly is disposed above the mover to limit the workpiece. The clamping assembly includes a clamping seat, an induction coil, a slider, and a clamping post. The clamping seat is fixedly installed on the top of the mover, and the induction coil is fixedly installed at the center of the clamping seat. Several sliders are slidably disposed on the top of the clamping seat, and a clamping post is fixedly installed on the top of each slider. The induction coil can attract multiple sliders to move closer to each other so that the clamping post clamps and limits the workpiece.

[0011] In a preferred embodiment of this utility model, the guide rail has two rails that are parallel to each other. The side wall of the guide rail is provided with an installation groove for installation, and the top of the guide rail is provided with several slots. The stator is fixedly installed in the corresponding slots.

[0012] In a preferred embodiment of this invention, two coils are fixedly installed at the bottom of the mover, with the two coils located directly above the two guide rails, and a Hall sensor is provided on one side of each coil.

[0013] In a preferred embodiment of the present invention, the clamping assembly further includes a clamping block and a magnet. The magnet is fixedly installed on the side of the slider near the induction coil, and the clamping block is fixedly installed on one side of the clamping post. The induction coil is capable of attracting the magnet.

[0014] In a preferred embodiment of the present invention, the clamping assembly further includes sliding channels, and the top of the clamping seat has several sliding channels arranged in a circular array, and the slider is slidably disposed in the corresponding sliding channels.

[0015] In a preferred embodiment of this utility model, the sliding channel is a rectangular groove, and the slider is fitted with the sliding channel with a clearance.

[0016] In a preferred embodiment of the present invention, the clamping assembly further includes a protective sleeve. The protective sleeve is fixedly installed on the top of the clamping seat by bolts. The protective sleeve is cylindrical, and the inner diameter of the protective sleeve is equal to the diameter of the clamping seat. The top of the protective sleeve is provided with several clearance grooves for the clamping column to pass through.

[0017] This utility model provides a conveying device for testing automotive HUD products. It has the following beneficial effects:

[0018] 1. This is a conveying device for testing automotive HUD products. The coil forms a closed-loop control through a Hall sensor. The stator is made of neodymium iron boron. The traveling wave magnetic field generated by the energized coil drives the mover to move radially along the guide rail. The Hall sensor is used to detect and provide feedback on the position of the mover in real time. By optimizing and improving the components for conveying the workpiece, compared with the existing technology that uses gear and belt drive, this solution uses magnetic levitation to convey the workpiece. It has high positioning accuracy, low vibration and noise, requires no lubrication and maintenance, and can reduce the interference of vibration on the imaging and detection of the workpiece.

[0019] 2. This is a conveying device for testing automotive HUD products. An induction coil generates a magnetic field that attracts magnets, causing multiple sliders to slide within corresponding sliding channels. The sliders move towards the center of the clamping base, driving the clamping column and clamping blocks closer to the center of the clamping base to clamp the workpiece. Taking eight sliders as an example, the clamping blocks are rectangular blocks, and silicone anti-slip sleeves can be fitted onto the outside of the clamping blocks. By clamping and positioning the workpiece with multiple clamping blocks, the stability and concentricity of the workpiece are ensured. The device offers high clamping accuracy over a wide range, improving its adaptability to clamping different shell workpieces and meeting the testing needs of various workpiece specifications.

[0020] 3. This conveying equipment for testing automotive HUD products uses a protective sleeve to shield the magnetic field generated by the induction coil, reducing electromagnetic interference to workpiece detection. At the same time, the protective sleeve shields and protects displaced components such as sliders, thereby improving safety performance and ensuring the stability of operation and testing.

[0027] A conveyor system for testing automotive HUD products, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes:

[0028] The guide rail 10 has several stators 12 fixedly installed on its top. The guide rail 10 has two rails, which are distributed in parallel. The side wall of the guide rail 10 has a mounting groove 11 for installation. The top of the guide rail 10 has several slots 13. The stators 12 are fixedly installed in the corresponding slots 13. A slide structure is set above the guide rail 10 for load-bearing. The slide structure includes a mover 20, a coil 21, and a Hall sensor 22. The bottom of the mover 20 is fixedly installed with the coil 21 and the Hall sensor 22. The coil 21 is located directly above the stator 12. Two coils 21 are fixedly installed at the bottom of the mover 20. The two coils 21 are located directly above the two guide rails 10 respectively. A Hall sensor 22 is set on one side of each coil 21.

[0029] In this scheme, the stator 12 is used to connect the controller and the frequency converter. The distribution interval of the stator 12 is smaller than the size of the coil 21. The coil 21 forms a closed-loop control through the Hall sensor 22. The stator 12 is made of neodymium iron boron. The traveling wave magnetic field generated by the energization of the coil 21 drives the mover 20 to move radially along the guide rail 10. The Hall sensor 22 is used to detect and provide feedback on the position of the mover 20 in real time. By optimizing and improving the components for conveying the workpiece, compared with the existing technology that uses gear and belt transmission, this scheme uses magnetic levitation to convey the workpiece. It has high positioning accuracy, low vibration and noise, can eliminate the need for lubrication and maintenance, and can reduce the interference of vibration on the workpiece imaging detection.

[0030] like Figure 4 and Figure 5 As shown, the clamping assembly is positioned above the mover 20 to limit the workpiece. The clamping assembly includes a clamping seat 30, an induction coil 31, a slider 32, and a clamping post 33. The clamping seat 30 is fixedly installed on the top of the mover 20, and the induction coil 31 is fixedly installed at the center of the clamping seat 30. Several sliders 32 are slidably arranged on the top of the clamping seat 30. A clamping post 33 is fixedly installed on the top of each slider 32. The induction coil 31 can attract multiple sliders 32 to move closer to each other so that the clamping post 33 clamps and limits the workpiece. The clamping assembly also includes a clamping block 34 and a magnet 35. The magnet 35 is fixedly installed on the side of the slider 32 closest to the induction coil 31, and the clamping block 34 is fixedly installed on the side of the clamping post 33. The induction coil 31 can attract the magnet 35. The clamping assembly also includes a sliding channel 36. Several sliding channels 36 are arranged in a circular array on the top of the clamping seat 30. The slider 32 is slidably arranged in the corresponding sliding channel 36. The sliding channel 36 is a rectangular groove, and the slider 32 is clearance-fitted with the sliding channel 36.

[0031] In this scheme, the magnetic field generated by the energized induction coil 31 attracts the magnet 35, causing multiple sliders 32 to slide within the corresponding sliding channels 36. The multiple sliders 32 move towards the center of the clamping seat 30. The sliders 32 drive the clamping column 33 and the clamping block 34 to move closer to the center of the clamping seat 30 to clamp the workpiece. Taking eight sliders 32 as an example, the clamping block 34 is a rectangular block. The outside of the clamping block 34 can be covered with a silicone anti-slip sleeve. By clamping and positioning the workpiece with multiple clamping blocks 34, the stability and concentricity of the workpiece are ensured. The clamping accuracy is high and the range is large, which improves the clamping adaptability of different shell workpieces and meets the inspection of multiple specifications of workpieces.

[0032] like Figure 4 As shown, the clamping assembly also includes a protective sleeve 37. The protective sleeve 37 is fixedly installed on the top of the clamping seat 30 by bolts. The protective sleeve 37 is a cylinder, and the inner diameter of the protective sleeve 37 is equal to the diameter of the clamping seat 30. Several clearance slots for the clamping column 33 to pass through are opened through the top of the protective sleeve 37. In this solution, the protective sleeve 37 can be made of aluminum alloy. The inner wall of the protective sleeve 37 is coated with silver nickel-based paint. The protective sleeve 37 can shield the magnetic field generated by the induction coil 31, reduce the interference of the electromagnetic field on the workpiece detection, and at the same time, the protective sleeve 37 can shield the displacement components such as the slider 32, thereby improving the safety performance.

[0033] The working principle of this utility model is as follows: The workpiece is placed on top of the protective sleeve 37, and the control switch of the induction coil 31 is activated. The magnetic field generated by the energized induction coil 31 attracts the magnet 35, causing multiple sliders 32 to slide in the corresponding sliding channels 36. The multiple sliders 32 move towards the center of the clamping seat 30. The sliders 32 drive the clamping column 33 and the clamping block 34 to approach the center of the clamping seat 30 to clamp the workpiece. Taking eight sliders 32 as an example, the clamping block 34 is a rectangular block. A silicone anti-slip sleeve can be fitted on the outside of the clamping block 34. The stator 12 is connected to the controller and frequency converter. The distribution interval of the stator 12 is smaller than the size of the coil 21. The coil 21 forms a closed-loop control through the Hall sensor 22. The stator 12 is made of neodymium iron boron material. The traveling wave magnetic field generated by the energized coil 21 pushes the mover 20 to move radially along the guide rail 10. The Hall sensor 22 is used to detect and provide feedback on the position of the mover 20 in real time, so as to achieve precise and stable conveying of the workpiece.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
