Description

Technical Field

[0001] The present invention relates to the technical field of HUD product assembly, and in particular to an assembly method for HUD products. Background Art

[0002] The HUD (HeadUpDisplay) display system is used to project important driving information such as speed and navigation onto the windshield in front of the driver, enabling the driver to view important driving information such as speed and navigation without having to lower or turn their head. This application can help the driver reduce cognitive load and improve perception ability. It needs to be adapted to the shape of the car's center console and windshield. With the development of AR technology and the demand for intelligent driving, HUD has been gradually emphasized by the industry. As Figure 1 shown, the existing HUD product 2 includes an outer housing 201 and an inner housing 204. The outer housing 201 is equipped with a projection light source 203 for display, and the inner housing 204 is equipped with an endoscope 205 corresponding to the projection light source 203. The inner housing 204 is also provided with a frame 206 adapted to the projection screen. The corresponding screen frame 206, the outer frame, and the inner frame of the housing form a frame to be snap-fitted. Step surfaces 202 are provided on both sides of the outer housing 201. The light source is reflected by the endoscope and fitted to the corresponding car glass. A plurality of corresponding fixing holes 207 are provided on the outer housing 201 and the inner housing 204. During assembly, the inner housing needs to be placed into the outer housing, the frames need to be fitted, and the outer housing and the inner housing are locked by fixing parts.

[0003] Due to the irregularity of HUD products, currently, corresponding customized assembly and testing equipment for HUD products are required. Since HUD products from different automobile manufacturers are generally not compatible with each other, and even when the same model of the same manufacturer is updated, the HUD system will be upgraded and transformed, resulting in frequent need to replace new customized equipment. When assembling HUD products of various specifications, the assembly and testing parts of various different specifications of equipment need to be redesigned accordingly, and operators also need to be retrained, resulting in slow assembly speed and delay in the production progress of new cars. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that when assembling HUD products of various specifications in the prior art, the assembly and testing parts of the existing equipment need to be redesigned, resulting in high production equipment costs and delays in the production progress of new cars. Thus, an assembly method for HUD products is provided.

[0005] To solve the above technical problem, the present invention provides an assembly method for HUD products, including the following steps:

[0006] Step S1: Provide an outer housing to be assembled, position the outer housing to be assembled, and lock the outer housing to be assembled;

[0007] Step S2: Obtain the positions of all the fixing holes on the outer shell, and insert multiple fixing parts into the corresponding positions of the fixing holes respectively;

[0008] Step S3: Place an inner shell to be press-fitted inside the outer shell, and use the fixing parts to pre-position the outer shell and the inner shell so that the outer shell and the inner shell are in contact;

[0009] Step S4: Drive the inner shell to approach the outer shell, and perform the first crimping and positioning along the first direction so that the outer shell and the inner shell are initially in close contact;

[0010] Step S5: Push the inner side of the inner shell to be press-fitted along the first direction, the second direction and the third direction respectively to perform the second crimping and positioning, so that the corresponding frames of the inner shell and the outer shell are in close contact and clamped again, and the outer shell and the inner shell are completely locked by the fixing parts.

[0011] In an embodiment of the present invention, in the step S1, the method for positioning the outer shell to be assembled is to use a jig assembly, the jig assembly is arranged on the frame, wherein the jig assembly includes a substrate and a plurality of support parts, place the outer shell to be assembled above the substrate, and support the outer shell to be assembled through the plurality of support parts. The substrate and the support parts are also provided with avoidance channels for the upper fixing parts and the locking fixing parts.

[0012] In an embodiment of the present invention, the method for locking the outer shell to be assembled is to use a locking assembly, wherein the locking assembly includes: a base, a rotating shaft is penetrated through the base, a pressing part is rotatably connected to the rotating shaft, the pressing part is provided with a first through hole and a second through hole which are communicated with each other, the first through hole is opened along the height direction of the pressing part, and the second through hole extends obliquely towards the direction of the outer shell to be assembled. By pulling down or pushing the pressing part through a first telescopic driving part, the pressing part cooperates with the first through hole and the second through hole to rotate while lifting, so that the pressing part of the pressing part approaches or moves away from the crimping step surface.

[0013] In an embodiment of the present invention, in step S1, when positioning and locking the outer shell to be assembled, place the outer shell to be assembled on the first side of the frame, and perform positioning and locking through a first jig assembly; in step S3, when pre-positioning the outer shell and the inner shell by using the fixing parts, first place the outer shell on the second side of the frame, perform positioning and locking through a second jig assembly, and then place the inner shell to be press-fitted inside the outer shell.

[0014] In an embodiment of the present invention, the plurality of support parts on the jig assembly on the first side of the frame have a height difference on both sides in the second direction or the third direction.

[0015] In one embodiment of the present invention, in step S4, the method for performing the first crimping and positioning on the housing to be assembled and the inner housing is to use a first press-fitting assembly. The first press-fitting assembly includes a pre-pressing head, which is arranged between the movable platform and the frame. The first press-fitting assembly is disposed on the movable platform, and the movable platform moves along a first direction on the second side of the frame through a lifting assembly, and drives the pre-pressing head to perform the first crimping and positioning on the inner housing along the first direction.

[0016] In one embodiment of the present invention, in step S4, when performing the first crimping and positioning on the housing to be assembled, a buffer assembly is also used. The buffer assembly is disposed on the movable platform, and the movable platform is disposed on the frame. The movable platform buffers during the first crimping and positioning through the buffer assembly. The buffer assembly includes a second guide sleeve disposed on the movable platform.

Through a fourth telescopic driving member on the movable platform, a push rod at its output end is driven to press the frame of the inner housing to be assembled along a third direction, so that the frame of the inner body is correspondingly clamped at the screen position of the outer housing.

[0019] In one embodiment of the present invention, in step S5, when performing the second crimping and positioning on the housing to be assembled, a third press-fitting assembly is also used. The third press-fitting assembly includes: a third telescopic driving member disposed on the movable platform. The output end of the third telescopic driving member is connected to a pressing head, and the end of the pressing head extends along the second direction. The pressing head is driven by the third telescopic driving member to press the housing to be assembled and the inner housing along the first direction.

[0020] In one embodiment of the present invention, it also includes detecting the assembled HUD product, which includes the following steps: pushing the second jig assembly to move along the second direction, so that a first detection sensor on the movable platform detects the assembled product.

[0021] In an embodiment of the present invention, when detecting the assembled HUD product, a plurality of first detection sensors are respectively rotated and adjusted so that the movement path of the projection area of the first detection sensor includes the corresponding fixture to be detected.

[0022] The above technical solution of the present invention has the following advantages compared with the prior art:

[0023] For an assembly method of a HUD product of the present invention, the housing to be assembled is locked on the fixture assembly through a locking mechanism, the position of the lifting assembly is adjusted up and down so that the first vision assembly can cover housings of different specifications, and the position of the fixture of the housing is detected. Fixtures are loaded, the locking mechanism is released, the housing is transferred to the assembly station and locked through another locking mechanism. The inner housing is placed into the housing, and the fixture extends into and passes through the corresponding fixture holes of the inner housing. The inner housing is squeezed from the first direction, the second direction and the third direction respectively through a pressing assembly so that the inner housing is closely attached to the housing, and the fixture is locked. The second lifting assembly and the movable platform are pushed along the second direction through the first driving assembly so that the first detection sensor on the movable platform scans and detects whether the fixture is locked properly.

[0038] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments given are not intended to limit the present invention. Embodiment

[0039] Refer toFigures 2 - 12 As shown in the figure, an assembly method of a HUD product of the present invention includes the following steps:

[0040] Step S1: Provide an outer housing 201 to be assembled, position the outer housing 201 to be assembled, and lock the outer housing 201 to be assembled;

[0041] Step S2: Obtain the positions of all the fixing holes 207 on the outer housing 201, and insert a plurality of fixing parts into the corresponding positions of the fixing holes 207 respectively;

[0042] Step S3: Place an inner housing 204 to be press-fitted into the outer housing 201, and use the fixing parts to pre-position the outer housing 201 and the inner housing, so that the outer housing 201 and the inner housing are in contact;

[0043] Step S4: Drive the inner housing 204 to approach the outer housing 201, and perform the first crimping positioning along the first direction, so that the outer housing 201 and the inner housing 204 are initially in close contact;

[0044] Step S5: Push the inner side of the inner housing 204 to be press-fitted along the first direction, the second direction and the third direction respectively, and perform the second crimping positioning, so that the corresponding frames of the inner housing 204 and the outer housing 201 are in close contact and clamped again, and the outer housing 201 and the inner housing 204 are completely locked through the fixing parts.

[0045] Taking Figure 3 as a reference, the first direction in this embodiment is the up and down direction, that is, the Z-axis direction, the second direction is the front and back direction, that is, the Y-axis direction, and the third direction is the left and right direction, that is, the X-axis direction. For an assembly method of a HUD product disclosed by the present invention, adjust the position of the lifting assembly up and down, so that the first vision component 53 can cover outer housings 201 of different specifications, and detect the positions of the fixing holes 207 of the outer housing 201, perform feeding of the fixing parts, release the locking mechanism 3, transfer the outer housing 201 to the assembly station and lock it through another locking mechanism 3, place the inner housing 204 into the outer housing 201, make the fixing parts extend into and pass through the corresponding fixing holes 207 of the inner housing 204, extrude the inner housing 204 from the first direction, the second direction and the third direction respectively through the press-fitting assembly, so that the inner housing 204 is in close contact with the outer housing 201, and perform locking of the fixing parts, push the second lifting assembly and the movable platform 73 along the second direction through the first driving assembly 71, so that the first detection sensor 742 on the movable platform 73 scans and detects whether the fixing parts are locked properly, and if there is a lack of fixing parts, supplement the fixing parts and continue to perform locking.

[0046] In the step S1, the method for positioning the housing 201 to be assembled is to use a jig component, which is arranged on the frame 1. The jig component includes a base plate 31 and a plurality of support members 32. The housing to be assembled is placed above the base plate 31, and the housing 201 to be assembled is supported by the plurality of support members 32. The base plate 31 and the support members 32 are also provided with avoidance channels for upper fixing members and locking fixing members. The plurality of support members 32 are arranged around the circumference of the base plate 31 and are adapted to the housing to be assembled. An inclined surface 34 is formed on one side of the support member 32 facing the housing to be assembled. The avoidance channel is composed of a third through hole and a first groove 36. The base plate 31 is provided with a third through hole along the first direction of the fixing member hole 207, and the support member 32 is provided with a first groove 36 along the first direction of the fixing member hole 207. The housing to be assembled is placed on the jig component. Due to the guiding action of the inclined surface 34 on the support member 32, the housing can be quickly guided and slid to a predetermined position and closely fit with the support member 32, and self-align under the pressing of gravity and the locking mechanism 3. The edge of the housing is supported by the plurality of support members 32, so that the housing can be stably held on the jig. The second fixing member machine passes the fixing member through the third through hole on the base plate 31 and aligns it with the fixing member hole 207 on the housing. When locking the fixing member, the first groove 36 on the support member 32 provides an avoidance space for the locking fixing member head, so that the fixing member can be smoothly tightened without interfering with the support member 32.

[0047] Referring to Figure 6 As shown, the method for locking the housing 201 to be assembled is to use a locking component 33. The locking component 33 includes: a base, a rotating shaft 335 is passed through the base, a pressing member 332 is rotatably connected to the rotating shaft 335, the pressing member 332 is provided with a first through hole 333 and a second through hole 334 which are communicated with each other. The first through hole 333 is opened along the height direction of the pressing member 332, and the second through hole 334 extends obliquely towards the housing 201 to be assembled. The height of the first through hole 333 is greater than that of the second through hole 334. By pulling or pushing the pressing member 332 by the first telescopic driving member 331, the pressing member 332 cooperates through the first through hole 333 and the second through hole 334, rotates while lifting, so that the pressing portion 336 of the pressing member 332 approaches or moves away from the pressing step surface 202.

[0048] Continuing to refer to Figure 6As shown, in this solution, one end of the pressing member 332 is rotatably connected to the output end of the first telescopic driving member 331, and the other end extends towards the direction of the housing 201 to be assembled with a pressing portion 336. The first through hole 333 and the second through hole 334 are strip-shaped through holes and are continuous at one end with each other, so that the rotating shaft 335 can slide in the first through hole 333 and the second through hole 334. The axis of the rotating shaft 335 is perpendicular to the plane where the extending direction of the first through hole 333 and the second through hole 334 is located. By driving the pressing member 332 to move up and down through the first telescopic driving member 331, when the rotating shaft 335 is at the lower end of the first through hole 333, the pressing member 332 inclines outwards, so that the pressing portion 336 is not in the Z-axis direction of the housing 201. At this time, it is in the unlocked state. By pulling down the pressing member 332 through the first telescopic driving member 331, the pressing member 332 is guided by the second through hole 334 and is slidably and rotatably connected to the rotating shaft 335, so that the pressing member 332 rotates while moving downwards, and the pressing portion 336 approaches above the stepped surface 202 of the housing 201. The pressing member 332 makes the rotating shaft 335 located in the first through hole 333. At this time, the pressing portion 336 is perpendicular to the body of the pressing member 332 and is adapted to the stepped surface 202 of the housing to be assembled. Continuing to pull down the pressing member 332 moves vertically downwards through the first through hole 333, so that the pressing portion 336 is pressed tightly on the stepped surface 202 of the housing 201 to lock the housing 201. In order to satisfy the simultaneous rotation and sliding of the pressing member 332, the piston rod of the first telescopic driving member 331 is rotatably connected to the lower end of the pressing member 332. In some embodiments, the bottom end of the first telescopic driving member 331 body can also be rotatably connected to the fixture assembly.

[0049] Referring to Figure 3 As shown, a loading station and an assembly station are respectively formed on the first side and the second side of the frame. The loading station and the assembly station are respectively detachably provided with fixture assemblies. The housing 201 to be assembled is locked on the fixture assembly through the locking mechanism 3 at the loading station. In this embodiment, the fixing member feeding mechanism and the fixing member locking mechanism are respectively a screw feeding machine and a screw locking machine, which include a first screw machine and a second screw machine. The first screw machine is used to screw the housing 201 on the first side of the frame 1, and the screw machine is used to lock the assembled housing 201 and the inner housing 204 on the second side of the frame 1. Start the first screw machine, so that the screw to be locked penetrates and is clamped in the fixing member hole 207 of the housing 201 to complete the screw feeding. Start the second screw machine to tighten the screw, so that the inner housing 204 and the housing 201 are locked and fixed through each screw.

[0050] In step S1, when positioning the housing 201 to be assembled and locking it, the housing 201 to be assembled is placed on the first side of the frame 1 and positioned and locked by the first jig assembly; in step S3, when pre-positioning the housing 201 and the inner shell with the fixing member, the housing 201 is first placed on the second side of the frame 1, positioned and locked by the second jig assembly, and then the inner housing 204 to be press-fitted is placed inside the housing 201. The jig assemblies are respectively arranged on both sides of the frame 1 to form the first jig assembly and the second jig assembly. The first jig assembly and the second jig assembly have the same structure as the jig assembly.

[0051] Referring Figure 4 As shown, as a preferred embodiment, a plurality of support members 32 on the jig assembly on the first side of the frame 1 have a height difference on both sides in the second direction or the third direction, making it easier for the inclined housing 201 to engage with the fixing member. Define the side of the frame 1 facing the operator as the front side. The height of the front support member 32 of the jig assembly on the first side of the frame 1 in the second direction is the first height, and the height of the rear support member 32 in the second direction is the second height. The first height is less than the second height, making the housing 201 on this jig assembly tilt forward, facilitating the operator's visual inspection and detection of the housing 201, and facilitating the taking and placing of the housing 201.

[0052] Referring Figure 7 、 Figure 11 As shown, in step S4, the method for performing the first crimping and positioning on the housing 201 to be assembled and the inner housing 204 is to use the first press-fitting assembly. The first press-fitting assembly includes a pre-pressing head 734. The pre-pressing head 734 is arranged between the movable platform 73 and the frame 1. The first press-fitting assembly is arranged on the movable platform 73. The movable platform 73 moves along the first direction on the second side of the frame 1 through the lifting assembly, and drives the pre-pressing head 734 to perform the first crimping and positioning on the inner housing 204 along the first direction.

[0053] Specifically, the pre-pressing head 734 is arranged along the first direction between the movable platform 73 and the second jig assembly. When the pre-pressing head 734 contacts the housing 201 to be assembled, continue to apply downward pressure to apply a pre-pressure to the parts to be assembled. In this embodiment, the pre-pressing head 734 is arranged on the movable platform 73. During the downward movement of the pre-pressing head 734, the fourth detection sensor 731 monitors the distance between the pre-pressing head 734 and the jig assembly in real time. When the preset pre-pressing distance is reached, the second lifting assembly 72 stops, completing the pre-pressing operation. Through the pre-pressing operation, the parts to be assembled can reach the pre-pressing initial state before the formal press-fitting, reducing the error during the formal press-fitting and improving the assembly accuracy and quality. Through the cooperation of the pre-pressing assembly, the push rod 756 moving along the third direction extends down to the position of the projection screen.

[0054] Referring to Figures 7 - 12 As shown, in step S4, when the housing 201 to be assembled is subjected to the first crimping and positioning, a buffer assembly 76 is also used. The buffer assembly 76 is arranged on the movable platform 73, and the movable platform 73 is arranged on the frame 1. The movable platform 73 is buffered by the buffer assembly 76 during the first crimping and positioning. The buffer assembly 76 includes a second guide sleeve 764 arranged on the movable platform 73. A second guide rod 761 is movably inserted through the second guide sleeve 764 and the movable platform 73. A limiting portion 763 is arranged at one end of the second guide rod 761. An elastic member 762 is arranged between the limiting portion 763 and the second guide sleeve 764. The other end of the second guide rod 761 is connected to an abutting platform 732. The buffer assembly 76 arranged on the movable platform 73 is used to buffer during the pressing and pre-pressing processes, reducing the damage to the equipment and the components to be assembled caused by the impact force. When the movable platform 73 drives the first pressing assembly and the second pressing assembly to move downward for pressing or pre-pressing operations, the pre-pressing head 734 first contacts the component to be assembled, and the contact pressure is detected by the fourth detection sensor 731, or a pen-type contact pressure sensor is arranged for contact detection and pressure detection. As the movable platform 73 continues to descend, the pre-pressing head 734 receives a reaction force, causing the movable platform 73 and the limiting portion 763 to squeeze the elastic member 762. The elastic member 762 is compressed and stores elastic potential energy. The compression process of the elastic member 762 plays a buffering role, absorbing a part of the impact force, so that the impact force during the pressing and pre-pressing processes is alleviated. When the pressing or pre-pressing operation is completed, the movable platform 73 rises, and the elastic member 762 releases the elastic potential energy, causing the abutting platform 732 to return to the initial position. By buffering, the wear of the equipment and the impact on the components to be assembled are reduced, improving the service life and assembly quality of the equipment. A clamping cylinder 733 is also arranged between the abutting platform 732 and the movable platform 73, which can start to further clamp the housing 201 and the inner housing 204 after fitting. When the clamping cylinder 733 is relaxed, it will not interfere with the elasticity of the buffer assembly 76. The elastic member 762 is a spring, sleeved on the second guide rod 761 and located between the limiting portion 763 and the end of the second guide sleeve 764.

[0055] Referring to Figures 7 - 8 As shown, in step S4, when the housing 201 to be assembled is subjected to the first crimping and positioning, an abutting member 35 is also used. The abutting member 35 is arranged on the substrate 31, and the abutting member 35 is arranged on one side of the fixing member hole position, used to support the fixing member hole 207 position, reducing the shell deformation amount and improving the assembly accuracy.

[0056] In step S5, the method for performing the second crimping and positioning on the housing 201 to be assembled and the inner housing 204 is to use a second pressing assembly, which includes: a first driving assembly 71 disposed on the frame 1. The first driving assembly 71 drives the movable platform 73 to move along the second direction, so that the pre-pressing head 734 pushes the inner housing 204 to be assembled again from the second direction. Through the fourth telescopic driving member 755 on the movable platform 73, the push rod 756 at its output end is driven to press the frame 206 of the inner housing 204 to be assembled along the third direction, so that the frame 206 of the inner body is correspondingly clamped at the screen position of the housing 201.

[0057] Referring to Figure 9 As shown, in step S5, when performing the second crimping and positioning on the housing 201 to be assembled, a third pressing assembly 75 is also used. The first pressing assembly, the second pressing assembly, and the third pressing assembly 75 form an assembly mechanism 7. The third pressing assembly 75 includes: a third telescopic driving member 752 disposed on the movable platform 73. The output end of the third telescopic driving member 752 is connected with a pressing head 753. The end of the pressing head 753 extends along the second direction. The pressing head 753 is driven by the third telescopic driving member 752 to press the housing 201 to be assembled and the inner housing 204 along the first direction. Specifically, the fourth telescopic driving member 755 drives the push rod 756 to press the screen of the inner housing 204 to be assembled and the housing 201 along the third direction. Before locking the fixing member, the pressing head 753 is driven by the third telescopic driving member 752 to move downward along the first direction.
