Description

Technical Field

[0001] This invention belongs to the field of head-up display technology, and particularly relates to a feeding device and a head-up display equipment production line. Background Technology

[0002] A head-up display (HUD) is an automotive optical display technology that projects key driving information into the driver's field of vision. Its core function is to create a virtual image through the windshield or a separate transparent medium, allowing the driver to access driving data without looking down at the instrument panel or central control screen, thus significantly improving driving safety and operational efficiency. As the core carrier of the optical components, the HUD housing must ensure dimensional precision, and the housing material must withstand high-temperature cycling to prevent deformation from affecting optical calibration. Furthermore, to reduce overall vehicle energy consumption, the HUD housing wall thickness must be controlled within a reasonable range while maintaining structural rigidity.

[0003] In the manufacturing process of head-up display (HUD) devices, it is usually necessary to load the casing onto the corresponding equipment for processing and then unload the completed casing. However, in existing feeding devices, the loading and unloading structures are separate and operate independently. During the intervals between two adjacent feeding strokes, the loading and unloading structures experience idle periods, which affects both feeding efficiency and production efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a feeding device and a head-up display production line, which aims to solve the problems of how to improve production efficiency and how to reduce the space occupied by the feeding device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a feeding device is provided for transferring materials. The feeding device includes a first transferring component, a second transferring component, and a rotating platform that rotates about a first axis. The first transferring component and the second transferring component are respectively disposed at both ends of the rotating platform. A transferring station and a processing station are respectively provided on opposite sides of the rotating platform. The rotating platform has a first position state and a second position state. When the rotating platform is in the first position state, the first transferring component and the second transferring component are respectively located at the transferring station and the processing station. The first transferring component receives the material to be processed at the transferring station, and the second transferring component picks up the processed material at the processing station. When the rotating platform is in the second position state, the first transferring component and the second transferring component are respectively located at the processing station and the transferring station. The second transferring component releases the processed material at the transferring station, and the first transferring component releases the material to be processed at the processing station.

[0007] In some embodiments, the first material transfer assembly includes a first driving member disposed on the rotating platform and a first clamping structure slidably connected to the rotating platform. Two first clamping structures are spaced apart, and the first driving member is used to drive the two first clamping structures to move towards each other or away from each other.

[0008] In some embodiments, the first clamping structure includes a first mounting plate slidably connected to the rotating platform and a first clamping member rotatably connected to the first mounting plate about a second axis. The first clamping member is used to clamp the material. The feeding device further includes a rotary drive member connected to one of the first clamping members. The rotary drive member is used to drive the corresponding first clamping member to rotate by a preset angle, so as to drive the material to rotate by a preset angle. The first axis is set at an angle to the second axis.

[0009] In some embodiments, the feeding device further includes a rotary cylinder, the rotary drive and the rotary cylinder are respectively disposed corresponding to two of the first clamping members, and the rotary output end of the rotary cylinder is connected to the corresponding first clamping member.

[0010] In some embodiments, the first clamping member includes a base plate rotatably connected to the first mounting plate, a first sliding driver connected to the base plate, and a first clamping block slidably connected to the base plate. Two first clamping blocks are spaced apart. The first sliding driver is used to drive the two first clamping blocks to move towards each other or away from each other. The sliding direction of the first clamping block is parallel to the extension direction of the first axis.

[0011] In some embodiments, the first axis and the second axis are perpendicular to each other.

[0012] In some embodiments, the second material transfer assembly includes a second driving member disposed on the rotary platform and a second clamping structure slidably connected to the rotary platform. Two second clamping structures are spaced apart, and the second driving member is used to drive the two second clamping structures to move towards each other or away from each other.

[0013] In some embodiments, the second clamping structure includes a second mounting plate slidably connected to the rotating platform and a second clamping member connected to the second mounting plate. The second clamping member includes a second sliding driver connected to the second mounting plate and a second clamping block slidably disposed therebetween. Two second clamping blocks are disposed at intervals. The second sliding driver is used to drive the two second clamping blocks to move toward each other or away from each other. The sliding direction of the second clamping block is parallel to the extension direction of the first axis.

[0014] In some embodiments, the rotating platform includes a drive structure, a first connecting plate connected to the output end of the drive structure, and a second connecting plate connected to the first connecting plate. The drive structure is used to drive the first connecting plate to rotate around the first axis. Two second connecting plates are arranged at intervals. The first material transfer component and the second material transfer component are respectively connected to the two second connecting plates.

[0015] Secondly, a head-up display (HUD) production line is provided, which includes the aforementioned feeding device.

[0016] The beneficial effects of this application are as follows: The feeding device of this application allows the rotary platform to switch between a first position state and a second position state by rotation. When the rotary platform is in the first position state, the first transfer component picks up the material to be processed at the transfer station, and the second transfer component picks up the processed material at the processing station. Then, the rotary platform switches to the second position state, and the second transfer component releases the processed material at the transfer station, while the first transfer component releases the material to be processed at the processing station. Therefore, this application can simultaneously complete loading and unloading in one rotation stroke of the rotary platform, thereby improving the efficiency of loading and unloading, enabling the production line to operate efficiently and thus improving production efficiency. Furthermore, by driving the material to transfer between the transfer station and the processing station through the rotation of the rotary platform, compared to a linear layout where the material transmission path is a straight line, the rotary platform drive method occupies less space and has a more compact structure, which is beneficial for reducing the space occupied by the feeding device.

[0028] Please see Figures 1 to 4This application provides a feeding device for transferring materials. The feeding device includes a first transferring component 10, a second transferring component 20, and a rotating platform 30 that rotates around a first axis. The first transferring component 10 and the second transferring component 20 are respectively disposed at both ends of the rotating platform 30. A transferring station 200 and a processing station 300 are respectively provided on opposite sides of the rotating platform 30. The rotating platform 30 has a first position state and a second position state. When the rotating platform 30 is in the first position state, the first transferring component 10 and the second transferring component... The first transfer component 10 is located at the transfer station 200 and the processing station 300, respectively. The first transfer component 10 picks up the material to be processed at the transfer station 200 and the second transfer component 20 picks up the processed material at the processing station 300. When the rotating platform 30 is in the second position, the first transfer component 10 and the second transfer component 20 are located at the processing station 300 and the transfer station 200, respectively. The second transfer component 20 releases the processed material at the transfer station 200 and the first transfer component 10 releases the material to be processed at the processing station 300.

[0029] In this embodiment, the material is specifically the HUD shell. The transfer station 200 and the processing station 300 are set at intervals. At the transfer station 200, a robot can be set up. The robot loads the material to be processed onto the first transfer component 10 or receives the processed material from the second transfer component 20.

[0030] In this embodiment, the rotating platform 30 rotates around a first axis, resulting in a first position state and a second position state. When the rotating platform 30 is in the first position state and the second position state, the orientations of the first transfer component 10 and the second transfer component 20 are different. Specifically, when the rotating platform 30 is in the first position state, the first transfer component 10 and the second transfer component 20 are located at the transfer station 200 and the processing station 300, respectively. When the rotating platform 30 is in the second position state, the first transfer component 10 and the second transfer component 20 are located at the processing station 300 and the transfer station 200, respectively.

[0031] The feeding device provided in this application allows the rotary platform 30 to switch between a first position and a second position by rotation. When the rotary platform 30 is in the first position, the first transfer component 10 picks up the material to be processed at the transfer station 200, and the second transfer component 20 picks up the processed material at the processing station 300. Then, the rotary platform 30 switches to the second position, and the second transfer component 20 releases the processed material at the transfer station 200, while the first transfer component 10 releases the material to be processed at the processing station 300. Therefore, this application can simultaneously complete loading and unloading within one rotation stroke of the rotary platform 30, thereby improving the efficiency of loading and unloading, enabling the production line to operate efficiently and thus improving production efficiency. Furthermore, by driving the material to transfer between the transfer station 200 and the processing station 300 through the rotation of the rotary platform 30, compared to a linear layout where the material transmission path is a straight line, the rotary platform 30 transmission method occupies less space and has a more compact structure, which is beneficial for reducing the space occupied by the feeding device.

[0032] Understandably, the first axis can be located at the center of the rotating platform 30, and the two sides of the rotating platform 30 are formed by the plane where the first axis is located, forming a material transfer station 200 and a processing station 300.

[0033] In some embodiments, the first material transfer assembly 10 includes a first driving member 11 disposed on the rotating platform 30 and a first clamping structure 12 slidably connected to the rotating platform 30. Two first clamping structures 12 are spaced apart, and the first driving member 11 drives the two first clamping structures 12 to move towards each other or away from each other. By providing two first clamping structures 12, the first driving member 11 drives the two first clamping structures 12 to move towards each other, and the two first clamping structures 12 jointly clamp the material, making the material stable during rotation. The clamping method is simple, and compared with adsorption of the material, it is not affected by fluctuations in adsorption force, ensuring that the material does not shake or shift during rotation, thereby improving the reliability of material movement.

[0034] In some embodiments, the feeding device further includes a first guide structure 60, which is connected between the rotary platform 30 and the first clamping structure 12. The first guide structure 60 guides the movement of the first clamping structure 12, making the movement of the first clamping structure 12 more stable and smooth, and effectively preventing the movement of the first clamping structure 12 from deviating, thus ensuring the reliability of clamping. Optionally, the first guide structure 60 includes a first guide rail 61 connected to the rotary platform 30 and extending along the movement direction of the first clamping structure 12, and a first slider 62 slidably connected to the first guide rail 61. The first clamping structure 12 is connected to the first slider 62, thereby realizing a sliding connection between the first clamping structure 12 and the first guide rail 61.

[0035] In some embodiments, the first clamping structure 12 includes a first mounting plate 121 slidably connected to the rotating platform 30 and a first clamping member 122 rotatably connected to the first mounting plate 121 about a second axis. The first clamping member 122 is used to clamp materials. The feeding device also includes a rotary drive member 40 connected to one of the first clamping members 122. The rotary drive member 40 is used to drive the corresponding first clamping member 122 to rotate by a preset angle, so as to drive the material to rotate by a preset angle. The first axis and the second axis are set at an angle. Specifically, the first axis extends along a first direction, the second axis extends along a second direction, and the first direction and the second direction are set at an angle.

[0036] Understandably, the rotary drive 40 drives the corresponding first clamping member 122 to rotate by a preset angle. Since the other first clamping member 122 is rotatable, and the two first clamping members 122 clamp the two ends of the material, the two first clamping members 122 and the material rotate synchronously. In this embodiment, the orientation of the material can be changed by driving the material to rotate by a preset angle. In a specific embodiment, the preset angle in this embodiment is 180°.

[0037] In some embodiments, the feeding device further includes a rotary cylinder 50. The rotary drive 40 and the rotary cylinder 50 are respectively configured corresponding to two first clamping members 122, and the rotation output end of the rotary cylinder 50 is connected to the corresponding first clamping member 122. It can be understood that the rotary drive 40 is a servo motor. Through the cooperation of the rotary drive 40 and the rotary cylinder 50, the servo motor is responsible for precise positioning, and the rotary cylinder 50 can adapt. Through the collaborative mechanism of precise control at the active end and adaptive operation at the driven end, the system reliability and cost-effectiveness are significantly improved while ensuring accuracy, and the reliability of material flipping is enhanced.

[0038] In some embodiments, the first clamping member 122 includes a base plate 1221 rotatably connected to the first mounting plate 121, a first sliding actuator 1222 connected to the base plate 1221, and a first clamping block 1223 slidably connected to the base plate 1221. Two first clamping blocks 1223 are spaced apart. The first sliding actuator 1222 drives the two first clamping blocks 1223 to move towards each other or away from each other. The sliding direction of the first clamping blocks 1223 is parallel to the extension direction of the first axis. Understandably, when the two first clamping blocks 1223 of one first clamping member 122 move towards each other, they clamp one end of the material. Similarly, the two first clamping blocks 1223 of the other first clamping member 122 also move towards each other, clamping the other end of the material. This reliably clamps the material and further improves its stability.

[0039] In some embodiments, the first clamping member 122 further includes a second guide structure connected between the base plate 1221 and the first clamping block 1223. The second guide structure guides the movement of the first clamping block 1223, making its movement more stable and smooth, and effectively preventing deviation during its movement, thus ensuring the reliability of the clamping. Furthermore, the specific structure of the second guide structure is similar to that of the first guide structure 60, and will not be described again here.

[0040] In some embodiments, the first axis and the second axis are perpendicular to each other, that is, the first direction and the second direction are perpendicular to each other. Specifically, if the first direction is vertical, then the second direction is horizontal. This not only makes the layout of the feeding device more aesthetically pleasing, but also, compared to parallel or staggered layouts, the dual-axis vertical layout occupies less space, which is beneficial for miniaturizing the feeding device.

[0041] In some embodiments, the second material transfer assembly 20 includes a second driving member 21 disposed on the rotating platform 30 and a second clamping structure 22 slidably connected to the rotating platform 30. Two second clamping structures 22 are spaced apart, and the second driving member 21 drives the two second clamping structures 22 to move towards each other or away from each other. By providing two second clamping structures 22, the second driving member 21 drives the two second clamping structures 22 to move towards each other, and the two second clamping structures 22 jointly clamp the material, making the material stable during rotation. The clamping method is simple, and compared with adsorption of the material, it is not affected by fluctuations in adsorption force, ensuring that the material does not shake or shift during rotation, thereby improving the reliability of material movement.

[0042] In some embodiments, a first guide structure 60 is also connected between the rotating platform 30 and the second clamping structure 22. The first guide structure 60 is used to guide the movement of the second clamping structure 22, making the movement of the second clamping structure 22 more stable and smooth, and effectively preventing the movement of the two clamping structures from deviating, thus ensuring the reliability of clamping.

[0043] In some embodiments, the second clamping structure 22 includes a second mounting plate 221 slidably connected to the rotating platform 30 and a second clamping member 222 connected to the second mounting plate 221. The second clamping member 222 includes a second sliding driver 2222 connected to the second mounting plate 221 and two slidably disposed second clamping blocks 2223. Two second clamping blocks 2223 are spaced apart. The second sliding driver 2222 is used to drive the two second clamping blocks 2223 to move towards each other or away from each other. The sliding direction of the second clamping blocks 2223 is parallel to the extension direction of the first axis. Understandably, the two second clamping blocks 2223 of one second clamping member 222 move towards each other to clamp one end of the material, and the two second clamping blocks 2223 of the other second clamping member 222 also move towards each other to clamp the other end of the material, thereby reliably clamping the material and further improving its stability.

[0044] In some embodiments, the rotary platform 30 includes a drive structure 31, a first connecting plate 32 connected to the output end of the drive structure 31, and a second connecting plate 33 connected to the first connecting plate 32. The drive structure 31 drives the first connecting plate 32 to rotate around a first axis. Two second connecting plates 33 are arranged at intervals. The first material transfer assembly 10 and the second material transfer assembly 20 are respectively connected to the two second connecting plates 33. Specifically, both second connecting plates 33 are perpendicular to the first connecting plate 32, and the first axis is perpendicular to the surface of the first connecting plate 32. The two second connecting plates 33 are symmetrically distributed around the first axis, so that the center of mass of the rotary platform 30 is strictly aligned with the rotation center, thereby improving the reliability of rotation. Furthermore, by setting the drive structure 31, it is ensured that the rotary platform 30 can still accurately position itself to the material transfer station 200 and the processing station 300 while rotating, thus improving the accuracy of material transfer.

[0045] This application also proposes a head-up display (HUD) production line, which includes a feeding device. The specific structure of the feeding device is as described in the above embodiments. Since this HUD production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] In summary, the feeding device provided in this application allows the rotary platform 30 to switch between a first position and a second position by rotation. When the rotary platform 30 is in the first position, the first transfer component 10 picks up the material to be processed at the transfer station 200, and the second transfer component 20 picks up the processed material at the processing station 300. Then, the rotary platform 30 switches to the second position, and the second transfer component 20 releases the processed material at the transfer station 200, while the first transfer component 10 releases the material to be processed at the processing station 300. Therefore, this application can simultaneously complete loading and unloading within one rotation stroke of the rotary platform 30, thereby improving the efficiency of loading and unloading, enabling the production line to operate efficiently and thus increasing production efficiency. Furthermore, by driving the material to transfer between the transfer station 200 and the processing station 300 through the rotation of the rotary platform 30, compared to a linear layout where the material transmission path is a straight line, the rotary platform 30 transmission method occupies less space and has a more compact structure, which is beneficial for reducing the space occupied by the feeding device.

Various modifications and variations can be made to this application by those skilled in the art.
