Description

Technical Field

[0001] This invention relates to the field of new energy vehicle headlight assembly equipment technology, specifically an automatic robot for assembling headlights for new energy vehicles. Background Technology

[0002] New energy vehicle headlights are key components that integrate lighting, signaling, and intelligent interaction. They not only achieve basic functions such as high / low beams, turn signals, and brake lights through light sources such as LEDs and lasers, but also incorporate intelligent features such as dynamic daytime running light effects, adaptive high / low beams, and cornering lights. Some high-end models are even equipped with innovative designs such as projection lights and interactive lights, which not only ensure driving safety, but also highlight the vehicle's technological feel and brand recognition through personalized lighting language. Their design must take into account energy efficiency (to meet the low power consumption requirements of new energy vehicles), aesthetic styling, and stringent regulatory standards.

[0003] In the production process of new energy vehicle headlights, due to design and product requirements, it is necessary to assemble headlights of various specifications. The assembly of new energy vehicle headlights is complex (integrating multiple systems such as optics, electronics, and mechanics), requires high precision (involving sealing, optical path calibration, etc.), and must adapt to the low energy consumption and intelligent characteristics of new energy vehicles. New energy vehicles, due to their higher intelligent requirements, have stricter requirements for the degree of automation in assembly (such as precise screw tightening by robots and machine vision calibration of optical paths) and quality inspection standards (such as airtightness testing and automated light pattern testing). Headlight assembly problems often stem from insufficient precision control (mechanical positioning, optical path calibration), non-standard process execution (sealing, welding, torque), and multi-system coordination errors (matching of electronics, optics, and mechanics). Traditional assembly equipment struggles to handle the assembly of headlights of various sizes, such as the sealing of lamp covers and housings. It is difficult to adjust the size of the gripping mechanism and accessories according to the size of the headlight, thus requiring additional equipment and increasing capital investment, resulting in certain production inconveniences. Therefore, an automated robot for assembling new energy vehicle headlights is proposed. Summary of the Invention

[0013] Preferably, the rotating mechanism includes an outer expansion shell, the dimensions of which are adapted to the dimensions of the outer expansion frame and the bottom limiting plate.

Several screw holes are opened on the top of the workbench, and the lampshade placement rack is fixed to the top of the workbench through the screw holes.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When the device is in use, the lamp cover is placed inside the lamp cover mounting bracket, and the lamp housing to be assembled is placed inside the vehicle lamp positioning mold. Then, the moving mounting base is moved by the horizontal ball screw moving mechanism, and the position of the accessory is collected and identified by the visual acquisition camera, which causes the vertical ball screw moving mechanism to move. When it moves to the top of the lamp cover mounting bracket, the high-precision electronically controlled telescopic column extends, causing the accessory gripping mechanism to contact the lamp cover. At this time, the suction mechanism is activated to generate suction inside the accessory gripping mechanism, adsorbing the lamp housing, and then... The movement of the horizontal and vertical ball screw moving mechanisms drives the lamp cover moving belt to be placed on the outside of the lamp housing inside the lamp positioning mold. Then, the circumferential gluing mechanism is activated to apply sealant to the opposite side of the lamp housing and lamp cover. At this time, the high-precision electronically controlled telescopic column moves down to squeeze the lamp cover and lamp housing. After the assembly is completed, the hydraulic telescopic rod is pushed back to open the mold half. The assembled lamp is taken out by the parts gripping mechanism and placed on the production line. Finally, the next assembly process is carried out. The whole system can adapt to the adsorption and gripping of lamps of different sizes, can apply sealant, and facilitate transmission. 2. When the bottom surface of the silicone suction head contacts the outer side of the car light, since some car lights are curved, the round shell moves down to make the silicone suction head contact the uneven outer surface of the car light. The internal holes of the silicone suction head connect and guide the gas, achieving the effect of air pressure adsorption. Due to the small aperture and flexibility of the silicone suction head, it can make close contact with the outer side of the car light. With the continuous air extraction of the suction mechanism, it can be used to adsorb and grab car light accessories, adapting to the gripping of car light accessories of various sizes. The silicone suction head is small in size and densely distributed, which can adapt to adsorption and gripping operations. 3. When the size or center of gravity of the adsorbed car light is unstable in the accessory gripping mechanism, slide the corresponding outer expansion shell into the inner side of the outer expansion frame. The structure of the silicone adsorption mechanism is the same as the relevant structure of the silicone suction head inside the accessory gripping mechanism, thereby expanding the adsorption area and adsorption effect. It can be used to adsorb and grip car light accessories of different sizes and can maintain the relative stability of the structure, which facilitates the increase of the device's adaptability.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-14This invention provides a technical solution: an automatic robot for assembling headlights for new energy vehicles, comprising a workbench 1, a lamp cover placement rack 2, a headlight positioning mold body 9, a rotating mechanism 10, an outward gripping mechanism 11, and a cover plate 12. A transverse ball screw moving mechanism 4 is mounted on the top of the workbench 1 via a bracket. The moving part of the transverse ball screw moving mechanism 4 is connected to a movable mounting base 401. Four vision acquisition cameras 402 are fixedly mounted on the outer side of the movable mounting base 401. A vertical ball screw moving mechanism 6 is fixedly mounted on the bottom of the movable mounting base 401. A high-precision electrically controlled telescopic column 601 is fixedly mounted on the moving part of the vertical ball screw moving mechanism 6. A part gripping mechanism 7 is fixedly mounted on the bottom end of the high-precision electrically controlled telescopic column 601. A circumferential glue application mechanism 8 is fixedly mounted on the top of the workbench 1.

[0035] The accessory gripping mechanism 7 includes a circular shell 701. Several positioning screws 702 are threadedly connected to the outer side of the top of the circular shell 701. An outer expansion frame 703 is fixedly sleeved on the outer side of the circular shell 701. A bottom limiting plate 704 is fixedly installed at the bottom of the outer expansion frame 703. Several positioning screw holes 705 are opened through the bottom limiting plate 704. Several sealing bolts 707 are threadedly connected to the inner side of the outer expansion frame 703. A support cylinder 708 is fixedly installed at the top of the inner cavity of the circular shell 701. A hollow air inlet hole 710 is opened at the top of the support cylinder 708. A sealing sliding cylinder 711 is movably sleeved on the inner side of the bottom end of the support cylinder 708. A return spring 709 is fixedly installed at the top of the sealing sliding cylinder 711. The sealing sliding cylinder 711 moves through the circular shell 701 through a rubber seal and extends to the bottom of the circular shell 701. A silicone suction head 706 is fixedly sleeved inside the sealing sliding cylinder 711. An air extraction mechanism 5 is connected to the top of the circular shell 701.

[0036] The headlight positioning mold body 9 includes a mold base 901. Two mold halves 902 are hinged to the top of the mold base 901. Wheel positioning grooves 903 are opened on the outer side of the top of the two mold halves 902. The mold base 901 is fixedly installed on the top of the workbench 1 by bolts. Hydraulic telescopic rods 904 are hinged to the opposite sides of the mold halves 902 by bolt seats. The other end of the hydraulic telescopic rods 904 is hinged to the top of the workbench 1.

[0037] The working principle of the above technical solution is as follows: In use, the lamp cover is placed inside the lamp cover mounting bracket 2, and the lamp housing to be assembled is placed inside the vehicle lamp positioning mold body 9. Then, the moving mounting base 401 is moved by the transverse ball screw moving mechanism 4, and the position of the part is collected and identified by the visual acquisition camera 402, which causes the vertical ball screw moving mechanism 6 to move. When it moves to the top of the lamp cover mounting bracket 2, the high-precision electronically controlled telescopic column 601 extends, causing the part gripping mechanism 7 to contact the lamp cover. At this time, the suction mechanism 5 is activated to generate suction inside the part gripping mechanism 7, adsorbing the lamp housing, and then moving it by the transverse ball screw moving mechanism 6. The movement of the ball screw moving mechanism 4 and the vertical ball screw moving mechanism 6 drives the lamp cover moving belt to be placed on the outside of the lamp housing inside the car lamp positioning mold body 9. Then, the circumferential glue coating mechanism 8 is activated to apply sealant to the opposite side of the lamp housing and the lamp cover. At this time, the high-precision electronically controlled telescopic column 601 moves down to squeeze the lamp cover and the lamp housing. After the assembly is completed, the hydraulic telescopic rod 904 is induced to retract and open the mold half 902. The assembled car lamp is taken out by the accessory gripping mechanism 7 and placed on the production line. Finally, the next assembly process is carried out. The whole system can adapt to the adsorption and gripping of car lamps of different sizes, can apply sealant, and facilitate transmission.

[0038] In another implementation scheme, such as Figures 1-14 As shown, the positioning screws 702 are evenly distributed in a circle on the top of the round shell 701, the positioning screw holes 705 are evenly distributed in a circle inside the bottom limit plate 704, and the sealing bolts 707 are threaded through the outer expansion frame 703 and extend into the interior of the round shell 701. The positions of the positioning screw holes 705 and the sealing bolts 707 correspond to the positions of the outer expansion frame 703.

[0039] The positioning screw 702 provides a fixed position for positioning parts 1003 and 1104, facilitating expansion and fixation during accessory installation and increasing structural stability. The sealing bolt 707 seals the communication port. When communication with the rotating mechanism 10 and the outward gripping mechanism 11 is required, the sealing bolt 707 can be removed. The sealing bolt 707 is a flat-head hexagonal bolt for easy disassembly and assembly. The positioning screw hole 705 is used to insert a screw to fix the cover plate 12, thereby sealing the bottom of the silicone suction head 706. This allows the suction area of ​​the silicone suction head 706 to be adjusted according to the size of the car light, thus increasing the fit of the structure.

[0040] In another implementation scheme, such as Figures 1-14 As shown, the return spring 709 is sleeved inside the support cylinder 708, and the top end of the return spring 709 is fixedly installed on the top of the inner cavity of the support cylinder 708. The support cylinder 708 and the sealing sliding cylinder 711 are evenly distributed in a circumferential linear filling inside the circular shell 701.

[0041] The return spring 709 provides elasticity to the sealing sliding cylinder 711 and the support cylinder 708. When the bottom surface of the silicone suction head 706 contacts the outer side of the car lamp, because part of the car lamp is curved, the round shell 701 moves downward, causing the silicone suction head 706 to contact the uneven outer surface of the car lamp. Gas is then connected and guided through the holes inside the silicone suction head 706, achieving a pressure adsorption effect. When the silicone suction head 706 contacts the car lamp and is compressed, it retracts from the sealing sliding cylinder 711, thereby compressing the return spring 709. This changes the relative position of the sealing sliding cylinder 711 and the support cylinder 708, thus changing the height of the silicone suction head 706. Due to the small aperture of the silicone suction head 706... With its flexible characteristics, it can make close contact with the outside of the headlight and, in conjunction with the continuous suction of the suction mechanism 5, can be used to adsorb and grab headlight accessories, adapting to the gripping of headlight accessories of various sizes. The silicone suction head 706 is small in size and densely arranged, which can adapt to the adsorption and gripping operation. The sealing sliding cylinder 711 and the round shell 701 are sealed and connected by a sealing sleeve at the penetration point, reducing air leakage at the holes of the sealing sliding cylinder 711 and the round shell 701, so that the airflow enters through the silicone suction head 706, and is finally introduced into the interior of the round shell 701 through the sealing sliding cylinder 711, the support cylinder 708, and finally through the hollow air inlet hole 710, thereby ensuring the air pressure adsorption path and being able to cooperate with the adsorption operation of the structure.

[0042] In another implementation scheme, such as Figures 1-3 As shown, the air extraction mechanism 5 includes an air pump 501 and air extraction hoses 502. The air pump 501 is fixedly installed on the top of the movable mounting base 401. There are two air extraction hoses 502, and the top ends of the two air extraction hoses 502 are connected to the input end of the air pump 501, and the bottom ends of the two air extraction hoses 502 are connected to the top of the circular shell 701.

[0043] When the air pump 501 generates airflow suction, the air suction force of the air pump 501 is relatively large. The airflow is drawn out from the inside of the cylindrical shell 701 through the air suction hose 502, which can promote airflow guidance and thus assist the air pressure adsorption operation.

[0044] In another implementation scheme, such as Figures 1-13As shown, the circumferential adhesive application mechanism 8 includes a concave circumferential track frame 801, which is fixedly installed on the top of the workbench 1. An internal gear ring 802 is fixedly installed on the outer side of the inner wall of the concave circumferential track frame 801. A drive gear 803 meshes with the inner side of the internal gear ring 802. A bearing seat 804 is movably sleeved on the outer side of the bottom end of the drive gear 803. A support ball wheel 816 is fixedly installed on the bottom of the bearing seat 804. The bottom of the support ball wheel 816 rolls in contact with the bottom of the inner cavity of the concave circumferential track frame 801. A servo motor 806 is drivenly connected to the top of the drive gear 803. The outer side of the output shaft of the servo motor 806 is movably extended to the top of the concave circumferential track frame 801 through a bearing sleeve. A fixing frame 805 is fixedly installed on the outer side of the servo motor 806. The two sides of the fixing frame 805 are... Several positioning wheels 808 are rolled on the bracket. The distribution shape of the positioning wheels 808 is adapted to the shape of the outer side of the concave circumferential track frame 801. A mounting frame 807 is fixedly installed on the top of the fixed frame 805. An electric turntable 809 is fixedly installed on the top of the mounting frame 807. A high-precision electrically controlled telescopic rod 810 is fixedly installed on one side of the electric turntable 809. A positioning frame 811 is fixedly installed at the output end of the high-precision electrically controlled telescopic rod 810. A positioning groove wheel 812 is rolled on the inner side of the positioning frame 811. An electric telescopic column 814 is fixedly installed on the top of the positioning frame 811. A glue gun 813 is fixedly installed at the output end of the electric telescopic column 814. A glue delivery tube 815 is connected to the input end of the glue gun 813. The bottom of the servo motor 806 is in sliding contact with the top of the concave circumferential track frame 801.

[0045] When the circumferential adhesive applicator 8 applies sealant, the adhesive delivery pipe 815 is pre-connected to the sealant pumping equipment. At this time, the servo motor 806 starts to rotate. The rotating shaft of the servo motor 806 drives the drive gear 803 to rotate. The meshing action of the drive gear 803 and the internal gear ring 802 produces a rotational effect. The rotational support of the bearing housing 804 maintains the stable position of the structure. The support ball wheel 816 supports the bearing housing 804, the drive gear 803, and the output shaft of the servo motor 806, thereby ensuring the position of the structure. Then, the fixing frame is fixed. The positioning wheel 808 rolls on the inner and outer arc surfaces of the concave circumferential track frame 801 to stabilize the position of the fixed bracket 805, thereby stabilizing the position of the servo motor 806. Each time, this causes the servo motor 806 and the mounting bracket 807 to move along the limits of the internal gear ring 802 and the concave circumferential track frame 801. Under the limitation of the positioning wheel 808, the servo motor 806 is also limited by the bearing sleeved on the outer side of its output shaft and the concave groove of the concave circumferential track frame 801, thus ensuring the relative stability of the structure and driving the mounting bracket 807 and... The movement of the electric turntable 809 ensures that the electric turntable 809 and the high-precision electrically controlled telescopic rod 810 align with the position of the headlight positioning mold body 9, causing the positioning groove wheel 812 to roll continuously inside the wheel positioning groove 903. This, in turn, ensures that the glue gun 813 maintains a circumferential relative position with the mold half 902. Then, the electric telescopic column 814 extends, causing the glue gun 813 to seal against the lamp housing and lamp cover. At this point, the sealant pumping equipment pumps sealant through the glue delivery pipe 815 and the glue gun 813 to the sealing area of ​​the lamp cover and lamp housing, thus achieving circumferential sealant application. After the first part gripping mechanism 7 is completed, it moves down to squeeze the lampshade and lamp housing together, thereby achieving a sealed assembly and facilitating the application of sealant. To increase the load-bearing capacity, the bottom of the servo motor 806 slides into contact with the top of the concave circumferential track frame 801. A graphite part is used for sliding support padding at this point to ensure the stability of the structure. The meshing of the drive gear 803 and the internal gear ring 802, along with the positioning wheel 808 and the outer limit of the concave circumferential track frame 801, can increase the load-bearing capacity and stability, making it easy to assist and modify the structure to meet the needs of other circumferential operations.

[0046] In another implementation scheme, such as Figures 1-13 As shown, the concave circumferential rail frame 801 is located outside the mold base 901, and the mold base 901 is located at the center of the concave circumferential rail frame 801. The output end of the hydraulic telescopic rod 904 is hinged to a hinge seat, which is fixed to the outside of the mold half 902 by bolts. The hydraulic telescopic rods 904 are symmetrically and evenly distributed on the outside of the mold half 902. The specifications and dimensions of the positioning groove wheel 812 are compatible with the specifications and dimensions of the wheel positioning groove 903.

[0047] The concave circumferential guide frame 801 and the mold base 901 are stably installed, ensuring the circumferential alignment of the glue gun 813 and the mold half 902, facilitating positional maintenance. The output end of the hydraulic telescopic rod 904 is bolted to the mold half 902. This design allows for easy assembly and disassembly of the hydraulic telescopic rod 904 and the mold half 902. When assembling other specifications of vehicle lights, the size and model of the vehicle light positioning mold body 9 are changed to fit the appropriate vehicle light. Finally, the mold base 901 is bolted to the top of the workbench 1 and connected via the hydraulic telescopic rod. The mounting base of 904 is bolted to the outside of the new mold half 902, thereby realizing the function of mold replacement. It enables the replacement of structural parts and the mold with limiting clamping. The extension and retraction of the hydraulic telescopic rod 904 can drive the opening and closing of the mold half 902. The inner side of the mold half 902 is provided with flexible rubber. When closed, it clamps and fixes the lamp placed on the inner side to reduce loosening. Due to design issues and mold opening reasons, and the fact that there are many sizes and specifications of car lamps, this design can be matched with car lamps to replace parts, thereby facilitating assembly operations and increasing the overall adaptability.

[0048] In another implementation scheme, such as Figures 4-6 , Figure 9 and Figure 12 As shown, the rotating mechanism 10 includes an outer expansion shell 1001. The dimensions of the outer expansion shell 1001 are adapted to the dimensions of the outer expansion frame 703 and the bottom limit plate 704. A positioning component 1003 is bolted to the top of the outer expansion shell 1001. The dimensions of the positioning screw 702 are adapted to the dimensions of the positioning component 1003. A silicone connecting hole 1002 is fixedly sleeved on the arc-shaped surface of the outer expansion shell 1001. The silicone connecting hole 1002 penetrates the outer expansion shell 1001 and connects to the outside of the outer expansion shell 1001. The dimensions of the silicone connecting hole 1002 are adapted to the dimensions of the sealing bolt 707. An air inlet guide hole 1006 is opened on the back of the outer expansion shell 1001. A bearing seat is fixedly installed on the top of the inner cavity of the outer expansion shell 1001. The inner side of the bearing housing 1009 is movably fitted with a mounting cylinder 1004, and the outer side of the mounting cylinder 1004 is fixedly fitted with a drive turbine blade 1008. The bottom end of the mounting cylinder 1004 passes through the outer expansion shell 1001 via a bearing and extends to the bottom of the outer expansion shell 1001. The inner side of the bottom end of the mounting cylinder 1004 is movably fitted with a rotating tool 1005. The internal thread of the mounting cylinder 1004 is connected with a fixing screw 1007, which passes through the mounting cylinder 1004 and extends into the interior of the rotating tool 1005. The air intake guide hole 1006 and the silicone connecting hole 1002 are linearly tangentially distributed on the outer side of the drive turbine blade 1008. The rotating tool 1005 includes a Phillips screwdriver, a flathead screwdriver, and a socket wrench.

[0049] When screws and bolts are needed to assemble the headlights, the corresponding rotating tool 1005 is installed inside the mounting cylinder 1004 and fixed through with the fixing screw 1007. Then, the sealing bolt 707 at the corresponding position of the round shell 701 and the headlight mounting is removed, and the outer expansion shell 1001 is slidably inserted into the opposite side of the outer expansion bracket 703. At this time, the silicone connecting hole 1002 aligns with the hole where the sealing bolt 707 is inserted, and the silicone connecting hole 1002 communicates with the hole. Then, the positioning part 1003 is rotated and fixed in the corresponding position of the outer expansion shell 1001 and the positioning screw 702 with screws. The bottom of the outer expansion shell 1001 is supported by the bottom limiting plate 704, the outer side is slidably engaged by the outer expansion bracket 703, and the top is secured by the positioning part 1003 and the positioning screw. 702 is positioned and fixed to achieve assembly. Then, when the suction mechanism 5 is activated, the airflow enters the interior of the outer shell 1001 through the air inlet guide hole 1006. At this time, the tangent of the airflow drives the drive turbine blade 1008 to rotate, which in turn drives the mounting drum 1004 and the rotating tool 1005 to rotate. The airflow enters the interior of the round shell 701 through the silicone connecting hole 1002 and is guided by the suction mechanism 5 to achieve bolt installation powered by airflow. When drilling holes for the headlights is required, the rotating tool 1005 can be replaced with a drilling tool accessory. The overall equipment is flexible. When installing with the outer gripping mechanism 11, the corresponding shielding cover 12 is installed at the bottom of the round shell 701 to block the airflow and limit the airflow, keeping the airflow pressure and enabling the screw installation.

[0050] In another implementation scheme, such as Figure 5 , Figure 9 and Figure 12 As shown, the outward-expanding gripping mechanism 11 includes an outward-expanding shell 1101. The dimensions of the outward-expanding shell 1101 are adapted to the dimensions of the outward-expanding frame 703 and the bottom limiting plate 704. A positioning component 1104 is bolted to the top of the outward-expanding shell 1101. The dimensions of the positioning screw 702 are adapted to the dimensions of the positioning component 1104. A silicone connecting hole 1103 is fixedly sleeved on the arc-shaped surface of the outward-expanding shell 1101. The dimensions of the silicone connecting hole 1103 are adapted to the dimensions of the sealing bolt 707. Several silicone adsorption mechanisms 1102 are installed inside the outward-expanding shell 1101. The dimensions of the silicone adsorption mechanisms 1102 are consistent with the dimensions of the silicone suction head 706, the support cylinder 708, the return spring 709, and the sealing sliding cylinder 711.

[0051] When the size or center of gravity of the adsorbed car light is unstable, the corresponding outer expansion shell 1101 is slid into the inner side of the outer expansion frame 703, and the bottom of the outer expansion shell 1101 is supported by the bottom limit plate 704. Then, the positioning part 1104 is aligned with the installation position of the positioning screw 702, and the sealing bolt 707 is removed. The silicone connecting hole 1103 is aligned with the hole removed from the sealing bolt 707. Thus, the structure of the silicone adsorption mechanism 1102 is equivalent to the internal structure of the accessory gripping mechanism 7 and the silicone suction head 706, thereby expanding the adsorption area and adsorption effect. It can be used to adsorb and grip car light accessories of different sizes, and can maintain the relative stability of the structure, which facilitates the increase of the adaptability of the device.

[0052] In another implementation scheme, such as Figure 7 , Figure 9 and Figure 12 As shown, the middle part of the shielding cover plate 12 is provided with several limiting holes 1201. The size of the limiting holes 1201 is adapted to the size of the silicone suction head 706. The outer edge of the shielding cover plate 12 is provided with several positioning screw holes 1202. The size of the positioning screw holes 1202 is adapted to the size of the positioning screw hole 705. The size of the shielding cover plate 12 is adapted to the size of the bottom limiting plate 704 and the round shell 701.

[0053] The cover plate 12 is sleeved on the bottom of the round shell 701, and the limiting hole 1201 is sleeved on the outside of the corresponding silicone suction head 706. Then, it is fixed by inserting screws into the positioning screw hole 2 1202 and positioning screw hole 1 705. This can cover the bottom of the silicone suction head 706. Multiple sizes of cover plates 12 are provided, so that the limiting hole 1201 at different positions can be set according to the required exposed area of ​​the silicone suction head 706, which is convenient for sealing operations. If the cover plate 12 does not have a limiting hole 1201, the bottom of the silicone suction head 706 can be completely covered, which can then be used in conjunction with the screw tightening and micro-hole drilling operations of the rotating mechanism 10, increasing the usability of the structure and facilitating operations.

[0054] In another implementation scheme, such as Figure 1 and Figure 2 As shown, four visual acquisition cameras 402 are symmetrically and evenly distributed on the outside of the mobile mounting base 401 in a rectangular shape. A smart control console 3 is fixedly installed on the top of the workbench 1. Several screw holes are opened on the top of the workbench 1, and the lampshade placement rack 2 is fixed to the top of the workbench 1 through the screw holes.

[0055] The visual acquisition camera 402 provides visual recognition acquisition hardware for the operation, and works in conjunction with the visual image acquisition and recognition system. The intelligent control console 3 has a built-in intelligent assembly system, which has a visual image acquisition and recognition system and an intelligent control system to identify and intelligently control the structure, realize automated assembly after visual recognition, and facilitate the operation with other production lines and equipment of the hollow system.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
