Description

Technical Field

[0001] This invention belongs to the field of angle light source production technology, and in particular relates to an assembly auxiliary component for a four-sided adjustable light source. Background Technology

[0002] With the rapid growth in demand for "multi-angle, rotatable, and adjustable beams" from industries such as LED lighting, machine vision, and film and television shooting, multi-angle light sources (usually composed of a central substrate and four circumferentially distributed angle adjustment blocks) have gradually become the mainstream in the market. In the mass production process of this type of product, the light source module and angle adjustment blocks need to be screwed onto the base and then installed into the lamp housing as a whole.

[0003] Existing technologies generally involve manually placing the base onto a simple fixture, then manually aligning, pre-tightening, and re-tightening the angle adjustment blocks one by one. Manual assembly is inefficient and cannot meet the needs of large-volume orders. It is also labor-intensive. The angle adjustment blocks and screws are small in size and numerous. Long-term repeated grasping and fastening can easily cause worker fatigue, and omissions and misassemblies occur frequently. At the same time, screws falling into the light source cavity can leave quality hazards.

[0004] Therefore, to solve the above problems, an assembly-aiding robotic arm is needed, which has high assembly efficiency and accuracy, and reduces the workload of workers. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an assembly auxiliary component for a four-sided adjustable light source, which solves the technical problems of low efficiency, high labor intensity, easy worker fatigue, and omissions and misassemblies in the prior art.

[0006] To achieve the above and other related objectives, the present invention provides an assembly auxiliary component for a four-sided adjustable light source, including a light source and a light source mounting base. Four angle adjustment blocks are circumferentially mounted on the upper side of the light source mounting base via bolts. The light source is locked between the adjustment blocks by screws. The assembly includes:

[0007] Assembly station;

[0008] An assembly auxiliary robot mechanism is provided, comprising a base gripping mechanism, a base fixing mechanism, and a screw-locking mechanism. The base gripping mechanism includes an electric rotary table, a first electric cylinder, a gripping arm, and a gripping part. The electric rotary table is fixedly mounted on the assembly table, and the first electric cylinder is vertically fixedly mounted on the rotating platform of the electric rotary table. The top end of the actuating end of the first electric cylinder is fixedly connected to the center of gravity of the gripping arm. The gripping arm has four mounting arms evenly arranged around its circumference, and the gripping part is fixedly mounted on the lower side of the mounting arms.

[0009] The base fixing mechanism is located below the mounting arm. After the gripping frame grips the light source mounting base, it is placed on the base fixing mechanism. The screw locking mechanism is symmetrically arranged on both sides of the base fixing mechanism.

[0010] In this way, the first electric cylinder moves the gripping arm up and down, which facilitates the gripping and releasing of the light source mounting base. The four mounting arms, which are set by the electric rotary table, quickly replenish the next light source mounting base when the multi-angle light source is moved out of the assembly plant after assembly, and simultaneously clamp another base, which improves the assembly efficiency.

[0011] Optionally, the gripping unit includes an electrically driven rotating gripper and a gripping frame. The electrically driven rotating gripper is fixedly mounted on the lower side of the mounting arm. The gripping frames are arranged in pairs on the gripping ends of the electrically driven rotating gripper. The gripping frames are integrally formed and have a fixed end and a clamping plate. The fixed end is fixedly mounted on the gripping end of the electrically driven rotating gripper. The clamping plate is L-shaped, and the bottom end of the clamping plate away from the fixed end has a downwardly recessed horizontal support clamping surface. By mounting the gripping frames on the gripper, when gripping the base, the gripping frame is located at the center of the base. When the gripper opens, the support clamping surface can provide support and clamping inside the light source mounting base, preventing the gripping frame from interfering with other mechanisms when the light source is assembled on the light source mounting base. Using the electrically driven rotating gripper, after assembling one side of the light source, the assembly can be switched to the next side to be assembled, ultimately completing the assembly of the light source on all four sides.

[0012] Optionally, the base fixing mechanism includes a placement platform, a four-jaw positioning chuck, and a limiting post. The four-jaw positioning chuck is fixedly installed on the assembly platform, located on one side of the base gripping mechanism. The placement platform is fixedly installed on the assembly platform via the mounting post and is located above the four-jaw positioning chuck. The placement platform has a through slot, which corresponds to the jaws of the four-jaw positioning chuck. The limiting post is vertically installed on the jaws of the four-jaw positioning chuck and slides within the slot. The top of the limiting post is higher than the plane at the upper end of the placement platform. The placement platform is also provided with a clearance groove to prevent interference with the clamping plate.

[0013] The base fixing mechanism can fix the light source mounting base, which is convenient for assembly with the light source. The screw locking mechanism can lock the light source between the angle adjustment blocks with screws. The symmetrically arranged screw locking mechanism can lock both sides of the light source at the same time, which improves the assembly efficiency. The four-jaw position chuck and limit post can fix the position of each light source mounting base in the center of the assembly table, which fixes the position of the angle adjustment block, improves the installation accuracy, and makes it easy to lock the light source between the two angle adjustment blocks.

[0014] Optionally, the screw-locking mechanism includes a locking mechanism and a driving mechanism, wherein the driving mechanism is located below the base fixing mechanism and is used to drive the locking mechanism.

[0015] The locking mechanism includes a fixed platform, a feeding platform, a locking part, and a second linear slide rail slider mechanism. The fixed platform is fixedly installed on the placement platform. The feeding platform is movably disposed on one side of the fixed platform through the second linear slide rail slider mechanism. The fixed platform and the feeding platform have through holes on the same axis. The locking part includes a spline shaft, a spline shaft sleeve, a connecting seat, and an electric push rod. The spline shaft sleeve is rotatably installed in the through hole of the fixed platform through a bearing. The spline shaft is axially movable within the spline shaft sleeve. The electric push rod is horizontally fixedly installed on the fixed platform. The connecting seat is located on the side of the fixed platform away from the feeding platform and is fixedly connected to the actuating end of the electric push rod. One end of the spline shaft away from the feeding platform is rotatably installed in the connecting seat through a bearing. The other end of the spline shaft is fixedly connected to a tightening shaft, and the tightening shaft and the spline shaft are coaxially arranged. The end of the tightening shaft away from the spline shaft is a cross-shaped groove head that can mate with a screw. By extending and retracting the electric push rod and driving the first gear to rotate, an axial movement and radial rotation force can be provided to the spline shaft, thereby causing the tightening shaft at the other end of the spline shaft to move toward the feed table and rotate radially during horizontal movement. This tightens the screw in the screw clamp on the other side of the feed table to the locking position of the light source mounting bracket and the light source, and locks both in place by rotation.

[0016] Optionally, a screw clamp is installed in the mounting hole of the feeding table via a guide sleeve, located at the end away from the fixed table. The screw clamp and the guide sleeve are connected and coaxially arranged. The end of the tightening shaft with a cross-grooved head is inserted and movably disposed within the guide sleeve. The screw clamp allows the screw to be positioned more effectively for tightening, and the guide sleeve enables the tightening shaft to be quickly inserted into the screw clamp to engage with the screw.

[0017] Optionally, a first gear is rotatably mounted on one side of the fixed platform via a rotating shaft, and a second gear is fixedly sleeved on the splined shaft sleeve. The first gear and the second gear are connected by a synchronous belt; the synchronous belt enables the first gear to drive the second gear to rotate.

[0018] Optionally, the drive mechanism includes a second motor, a gear commutator, and a gear transmission unit. The second motor is fixedly mounted on the assembly table, and its output end is connected to the gear commutator. The gear transmission unit is symmetrically fixedly connected to the shafts on both sides of the gear commutator, and the locking mechanism is connected to the gear transmission unit. Using the gear commutator, only the output of one second motor is needed to reverse the transmission directions of the two drive shafts, thus satisfying the requirement for simultaneous locking of screws on both sides and saving assembly time.

[0019] Optionally, the gear transmission unit includes a first transmission shaft and a second transmission shaft. There are two first transmission shafts, which are fixedly connected to the extended shafts on both sides of the gear commutator on the same axis, and each end is provided with a bevel gear. The second transmission shaft is rotatably mounted on the lower side of the placement platform through a transmission shaft mounting block, and is symmetrically arranged on both sides of the second motor. The axes of the first transmission shaft and the second transmission shaft are perpendicular to each other.

[0020] Both ends of the second drive shaft are fixedly provided with bevel gears, and the first drive shaft and the second drive shaft are meshed with each other through bevel gears;

[0021] A bevel gear is also provided on the shaft on which the first gear is mounted, and the other end of the second drive shaft meshes with the first gear through the bevel gear.

[0022] The transmission gears and transmission shaft enable the first gears on both sides to rotate synchronously, thereby simultaneously tightening the screws.

[0023] Optionally, the mounting shafts of the first gears on the same side are connected via a synchronous belt pulley mechanism. The synchronous belt pulley mechanism allows two locking mechanisms on one side to simultaneously lock screws into the light source mounting base and the light source.

[0024] Optionally, the limiting post has a plug-in groove, and the plug-in groove has a plug-in fitting limiting plate. The limiting plate is symmetrical on both sides of the plug-in groove. The lower side of the feeding table has a slot, and the limiting plate is engaged in the slot of the feeding table. Through the plug-in groove, when the four-jaw positioning chuck limits the light source mounting base, the limiting plate pulls the feeding table. While limiting the light source mounting base, the screw output outlet of the screw machine chuck on the feeding table is brought close to the mounting hole of the angle adjustment block, so that the screw can be locked into the light source mounting base and the light source module under the action of the spline shaft and the tightening shaft.

[0025] The beneficial effects of this invention are as follows:

[0026] Using this invention can reduce the workload of workers, improve assembly efficiency, increase assembly accuracy and quality, and reduce omissions and misassemblies. Attached Figure Description

[0038] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0039] Please see Figures 1 to 11It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0040] like Figures 1-11 As shown, a multi-angle light source system assembly production line includes: an assembly table 1, on which four light source modules 12 are locked onto a light source mounting base 13 at an assembly station 11. The light source mounting base 13 is typically composed of a central substrate and four circumferentially distributed angle adjustment blocks 132. The light source modules 12 are locked between two adjacent angle adjustment blocks 132 by screws. The central substrate is hollow in the middle.

[0041] In this embodiment, a light source mounting base transport assembly 2 is provided on one side of the assembly table 1 for transporting the light source mounting base 13 to the assembly table 1. The light source mounting base transport assembly 2 includes a first conveyor belt mechanism 21, a base lifting mechanism 22, and a base limiting mechanism 23. The width of the first conveyor belt mechanism 21 is smaller than that of the light source mounting base 13, so that the two sides of the light source mounting base 13 extend beyond the first conveyor belt mechanism 21, which makes it easier for the base lifting mechanism 22 to lift the light source mounting base 13 upward. The lifted light source mounting base 13 is easier to be grasped.

[0042] like Figures 1-5 As shown, the base lifting mechanism 22 includes a lifting section and an adjusting section for adjusting the spacing between the lifting sections. The lifting section includes a second conveyor belt mechanism 2211 and lifting blocks 2212. The second conveyor belt mechanisms 2211 are arranged in pairs and mounted on the adjusting section, vertically and symmetrically arranged on both sides of the first conveyor belt mechanism 21. The transmission direction of the two second conveyor belt mechanisms 2211 is towards the first conveyor belt mechanism 21. The lifting blocks 2212 are evenly distributed on the circumferential surface of the conveyor belt of the second conveyor belt mechanism 2211. The lifting blocks 2212 on the two second conveyor belt mechanisms 2211 are arranged in pairs and move synchronously. When the lifting blocks 2212 are close to the first conveyor belt mechanism 21, they are perpendicular to the second conveyor belt mechanism 2211. The paired lifting blocks 2212 have a support plane of the same height for supporting the light source mounting base 13.

[0043] Specifically, the adjustment unit includes a fixed frame 2221, an adjustment frame 2222, a linear slide rail 2223, a slider 2224, a lead screw 2225, and a drive motor 2226. The fixed frame 2221 is fixedly installed below the first conveyor belt mechanism 21. The linear slide rail 2223 is fixedly installed on the fixed frame 2221. Two sliders 2224 are slidably installed on one linear slide rail 2223. The direction of movement of the sliders 2224 is perpendicular to the conveying direction of the first conveyor belt mechanism 21. The adjustment frame 2222 has two sliders symmetrically installed on the two sliders 2224. The adjustment frame 2222 and the sliders 2224 are located on both sides of the first conveyor belt mechanism 21. The second conveyor belt mechanism 2211 is installed on the adjustment frame 2222. To make the movement of the adjustment frame 2222 more stable, two linear slide rails 2223 are provided. The lower end of the adjustment frame 2222 is on the same side of the two linear slide rails 2223. The slider 2224 is fixedly connected, and the lead screw 2225 is rotatably mounted on the fixed frame 2221. The axis of the lead screw 2225 is horizontal with the direction of movement of the slider 2224. The lead screw 2225 is located between two linear slide rails 2223. The lead screw 2225 is a bidirectional lead screw with opposite threads at both ends, and nuts are screwed onto both ends. Connecting blocks 2228 are fixedly mounted on the lower ends of the two adjusting frames 2222. Two nuts are fixedly set in the connecting blocks 2228 respectively. The drive motor 2226 is fixedly mounted on the fixed frame 2221, and its output end is connected to one end of the lead screw 2225. When the drive motor 2226 is working, it can drive the lead screw 2225 to rotate, so that the adjusting frames 2222 move closer or further apart, thereby changing the distance between the lifting blocks 2212. When assembling different models of multi-angle light sources, the appropriate spacing can be selected according to the size of the light source mounting base 13, which improves the applicability.

[0044] like Figure 4As shown, in this embodiment, the base limiting mechanism 23 is installed on the first conveyor belt mechanism 21, including a base limiting plate 231 and base limiting studs 232. The base limiting plate 231 is horizontally mounted in an n-shape above the tail end of the first conveyor belt mechanism 21. The lower side of the base limiting plate 231 is spaced 233 mm apart from the surface of the first conveyor belt mechanism 21 to avoid interference between the first conveyor belt mechanism 21 and the base limiting plate 231. There are two base limiting studs 232, which are horizontally and symmetrically installed below both ends of the base limiting plate 231 and located on both sides of the first conveyor belt mechanism 21. The two sides of the first conveyor belt mechanism 21 are symmetrically fixed. A base limiting stud mounting block 234 is installed, which has a horizontal through hole 235. The base limiting stud 232 is horizontally and movably installed in the base limiting stud mounting block 234 through the through hole. A nut is screwed onto the end of the base limiting stud 232 away from the base limiting plate 231. By rotating the nut, the base limiting plate 231 can be moved horizontally above the first conveyor belt mechanism 21, which can stop the movement of the light source mounting base 13 and keep it in the position where the lifting block 2212 can easily lift the light source mounting base 13. The appropriate stopping position can be selected according to the size of the light source mounting base 13, which improves the applicability.

[0045] After the light source mounting base 13 is lifted, it needs to be transferred to the assembly station on the assembly table 1 by the assembly auxiliary robot mechanism 3.

[0046] like Figure 1 , Figure 2 and Figures 5-9 As shown, in this embodiment, the assembly auxiliary robot arm mechanism 3 includes a base gripping mechanism, a base fixing mechanism, and a screw locking mechanism. The base gripping mechanism grips the light source mounting base 13 from the base lifting mechanism and transports it to the base fixing mechanism for fixing. After the light source module 12 is in place, the screw locking mechanism then locks the light source module 12 onto the light source mounting base 13.

[0047] Specifically, the base gripping mechanism 31 includes an electric rotary table 311, a first electric cylinder 312, a gripping arm 313, and a gripping part 314. The electric rotary table 311 is fixedly installed on the assembly table 1 and close to the first conveyor belt mechanism 21. The first electric cylinder 312 is vertically fixedly installed on the rotating platform 3111 of the electric rotary table 311. The top end of the actuating end of the first electric cylinder 312 is fixedly connected to the center of gravity of the gripping arm 313. The gripping arm 313 has four mounting arms 3132 evenly arranged around its circumference. The gripping part 314 is fixedly installed on the lower side of the mounting arms 3132. Under the action of the first electric cylinder 312, the mounting arms 3132 can move up and down, thereby facilitating the gripping part 314 to grip and release the light source mounting base 13.

[0048] Specifically, the gripping unit 314 includes an electrically driven rotating gripper 3141 and a gripping frame 3142. The electrically driven rotating gripper 3141 is vertically fixedly mounted on the underside of the mounting arm 3132. The gripping frames 3142 are arranged in pairs on the gripping ends of the electrically driven rotating gripper 3141. The gripping frames 3142 are integrally formed and have a fixed end 31421 and a clamping plate 31422. The fixed end 31421 is fixedly connected to the gripping end of the electrically driven rotating gripper 3141. The clamping plate 31422 is L-shaped, and the bottom of the clamping plate 31422 is far from the gripping end. One end of the fixed end 31421 has a downwardly recessed support clamping surface 31423. The electric rotating gripper 3141 is lowered to the lifting mechanism 22 under the action of the first electric cylinder 312, and the gripping frame 3142 is located in the middle of the light source mounting base 13. When the gripping end of the electric rotating gripper 3141 is opened, the gripping frame 3142 is opened, and the two support clamping surfaces 31423 abut against the inner side and the lower side of the light source mounting base 13 respectively, thereby fixing the light source mounting base 13 on the gripping frame 3142.

[0049] Specifically, the base fixing mechanism includes a placement platform 321, a four-jaw positioning chuck 322, and a limiting post 323. The four-jaw positioning chuck 322 is fixedly installed on the assembly platform 1, located on one side of the base gripping mechanism 31. The placement platform 321 is fixedly installed on the assembly platform 1 via the mounting post 3211, and is located above the four-jaw positioning chuck 322. The placement platform 321 has a through slot 3212, which corresponds to the jaws of the four-jaw positioning chuck 322. The limiting post 323 is vertically installed on the jaws of the four-jaw positioning chuck 322. The limiting post 323 moves within the slot 3212. The top of the limiting post 323 is 2-4 mm higher than the upper plane 3213 of the placement platform 321. The placement platform 321 is also provided with a clearance groove 3214 to prevent interference when the clamping plate 31422 rotates.

[0050] After the light source mounting base 13 is transported to the top of the placement platform 321, the first electric cylinder 312 descends, placing the light source mounting base 13 on the placement platform 321. Then, the clamping plate 31422 is released, and the four limit pins 323 on the four-jaw positioning chuck 322 simultaneously clamp the light source mounting base 13, fixing its position. This allows the mounting hole 1321 of the angle adjustment block 132 to reach the position of the screw to be locked. When the light source module 12 reaches between the angle adjustment blocks 132, the screw is provided by the screw locking mechanism, and the light source module 12 is locked between the angle adjustment blocks 132.

[0051] Specifically, the clamping end of the electric rotating gripper 3141 can also rotate. After the light source module 12 on one side is assembled between the angle adjustment blocks 132, the four-jaw positioning chuck 322 is released, and the electric rotating gripper 3141 clamps the light source mounting base 13 again. Then it rotates 90 degrees. After the rotation, the clamping plate 31422 is released again, and the four-jaw positioning chuck 322 clamps again. After the light source module 12 arrives, it is locked again using the screw locking mechanism. After rotating 3 times, the four light source modules 12 are locked.

[0052] like Figure 6 and Figure 9As shown, in this embodiment, the screw-locking mechanism is symmetrically installed on the assembly table 1 and located on both sides of the placement table 321. It includes a locking mechanism 331 and a driving mechanism 332. There are four locking mechanisms 331, which are arranged in pairs and symmetrically arranged on both sides of the placement table 321. Two sets of locking mechanisms 332 are provided. One set of driving mechanisms 332 can drive two sets of locking mechanisms 331 simultaneously to lock the two light source modules 12 onto the light source mounting base 13 at the same time. The locking mechanism 331 includes a fixing platform 3311 and a feeding platform 3312. A second slider 3313 is fixedly installed on the lower side of the fixing platform 3311. A second slide rail 3314 is provided on the lower side of the feeding table 3312. The second slider 3313 and the second slide rail 3314 are slidably engaged. A guide shaft 3309 is also provided on the feeding table. A linear bearing coaxial with the guide shaft is fixedly installed in the fixed table. The guide shaft 3309 is inserted into the linear bearing in the fixed table. Through the action of the linear bearing, the second slide rail and the second slider, the feeding table 3312 can move on one side of the fixed table 3311, so that the feeding table 3312 can approach the mounting hole of the light source mounting base 13 when the light source mounting base 13 is limited by the limiting post 323. The fixed table 3311 and the feeding table Each of the 3312 has through holes. The through holes on the fixed platform 3311 and the through holes on the feeding platform 3312 are coaxially arranged and correspond one-to-one. When the light source module 12 is installed on the light source mounting base 13, two screws need to be fastened on one side. Therefore, two through holes are respectively provided on the fixed platform 3311 and the feeding platform 3312 at the corresponding fastening positions. Splined shaft sleeves 3315 are rotatably installed in the two through holes of the fixed platform 3311 through bearings. A splined shaft 3316 is movably arranged in the splined shaft sleeve 3315. A tightening shaft 33 is fixedly installed at the end of the splined shaft 3316 near the feeding platform 3312. 17. The end of the tightening shaft 3317 near the feeding table 3312 has a cross-shaped groove head that can cooperate with the screw. The end of the spline shaft 3316 away from the feeding table is located on the side of the fixed table 3311 away from the feeding table 3312. It rotates in the connecting seat 3318 through the bearing. An electric push rod 3319 is also fixedly installed on the fixed table 3311. The actuating end of the electric push rod 3319 is set towards the side away from the feeding table 3312. The actuating end of the electric push rod 3319 is fixedly connected to the connecting seat 3318. Through the electric push rod 3319, the spline shaft 3316 can move axially in the spline shaft sleeve 3315.

[0053] In this embodiment, a first gear 3301 is rotatably mounted below the fixed platform 3311 via a rotating shaft, and a second gear 3302 is also interference-fitted onto the spline shaft sleeve 3315. The first gear 3301 and the second gear 3302 are connected by a synchronous belt 3308. When the first gear 3301 rotates, the second gear 3302 can rotate, thereby causing the spline shaft sleeve 3316 and the spline shaft to rotate.

[0054] Specifically, in order to make the two splined shafts 3316 rotate synchronously, a third gear 3304 is provided on one of the splined shaft sleeves 3315. The third gear 3304 is connected to the second gear 3302 through a timing belt 330.

[0055] In this embodiment, a guide sleeve 3303 is installed in the through hole of the feeding table 3312. A screw chuck 3305 is fixedly installed at the end of the guide sleeve 3303 away from the fixed table 3311. The screw chuck 3305 and the guide sleeve 3303 are internally connected. The tightening shaft 3317 with a cross-grooved head is inserted and movably disposed in the guide sleeve 3303. When the spline shaft 3316 moves axially under the action of the electric push rod 3319 and drives the spline shaft 3316 to rotate radially under the rotation of the first gear 3301, the tightening shaft 3317 can be inserted into the screw chuck 3305 and cooperate with the screw inside. Then the screw is screwed into the space between the light source base mounting bracket and the light source module to lock the two together.

[0056] Specifically, the screw machine chuck 3305 is connected to a conduit, which is connected to a screw feeder for providing screws.

[0057] The specific screw feeder is existing technology, and its principle will not be described further and is not shown in the figure.

[0058] like Figure 8 As shown, in this embodiment, the drive mechanism 332 includes a second motor 3321, a gear commutator 3322, and a gear transmission unit. The second motor 3321 is vertically fixed on the assembly platform 1, with its output end facing upwards and connected to the main shaft of the gear commutator 3322. The gear commutator 3322 is fixedly installed below the placement platform 321. The gear commutator 3322 is a T-series gear commutator with two protruding shafts. The gear transmission unit is symmetrically connected to the two protruding shafts of the gear commutator and is connected to the first gear 3301 in one of the two locking mechanisms near the second motor 3321. When the second motor 3321 outputs, the gear commutator 3322 enables the protruding shafts on both sides to rotate in different directions. Under the action of the gear transmission unit, the first gears 3301 on both sides of the placement platform rotate in opposite directions, thereby simultaneously locking the four locking positions of the two light source modules with screws.

[0059] Specifically, the gear transmission unit includes a first transmission shaft 3323 and a second transmission shaft 3324. One end of the first transmission shaft 3323 is fixedly connected to the extension shaft of the gear commutator 3322, and a bevel gear is fixedly installed at the other end. The second transmission shaft 3324 is rotatably mounted on the lower side of the placement platform 321 through the transmission shaft mounting block 3325. Its axis is perpendicular to the axis of the first transmission shaft 3323, and both ends of the second transmission shaft 3324 have bevel gears. A bevel gear is provided on the shaft 3310 of the first gear 3301 near the second motor 3321. The second transmission shaft 3323 meshes with the bevel gears on the first transmission shaft 3323 and the shaft of the first gear 3301 near the second motor 3321 through the bevel gears.

[0060] In this embodiment, the locking mechanism 331 on the same side is connected by a synchronous belt pulley mechanism 333; the use of a synchronous belt pulley mechanism can reduce interference between the four-jaw positioning chuck and the locking mechanism.

[0061] Specifically, in the locking mechanism 331 on the same side, a synchronous belt pulley mechanism 333 is provided between the rotating shafts used to install the first gear 3301. When the driving unit 332 drives the nearest first gear 3301 to rotate, the other first gear 3301 on the same side rotates synchronously.

[0062] like Figure 9 As shown, in this embodiment, to facilitate the simultaneous approach of the two feeding platforms 3312 on the same side to the angle adjustment block 132, and to allow the screw clamp 3305 to reach the screw-locking position of the angle adjustment block 132, a slot is provided on the lower side of each feeding platform 3312. The same limiting plate 3333 is engaged in the slots of both feeding platforms 3312. The limiting post 323 has an insertion slot, and the middle part of the limiting plate 3333 is inserted into the insertion slot 3231 of the limiting post 323. When the four-jaw positioning chuck 322 limits the position of the light source mounting base 13, the screw clamp 3305 can simultaneously approach the angle adjustment block 132, facilitating the tightening of the shaft 3317 and the screw to mount the light source module 12 onto the angle adjustment block 132.

[0063] like Figure 2 As shown, in this embodiment, the light source module 12 is transported to the assembly station 11 of the assembly table 1 by the light source transport gripping component 4. The light source transport gripping component 4 includes a light source gripping mechanism and a light source transport mechanism. The light source transport mechanism transports the light source module 12 to the gripping station, and then the light source gripping mechanism grips and transports it to the assembly station 11.

[0064] like Figure 6 , Figure 10 and Figure 11As shown, specifically, the light source transport mechanism includes a third conveyor belt mechanism 421, a light source guiding mechanism, and a light source limiting mechanism. The third conveyor belt mechanism 421 is located on the side of the assembly table 1 away from the first conveyor belt mechanism 21. The light source guiding mechanism and the light source limiting mechanism are both installed on the third conveyor belt mechanism 421. The light source guiding mechanism is symmetrically arranged on both sides of the third conveyor belt mechanism 421 and includes a guide frame 4221, a rotating shaft 4222, a guide belt 4223, and a third electric cylinder 4224. The third electric cylinder 4224 is horizontally fixed to the third conveyor belt mechanism via a bracket 424. On the structure 421, the extended end of the third electric cylinder 4224 is set towards the third conveyor belt mechanism 421. The guide frame 4221 is fixedly installed at the top of the extended end of the third electric cylinder 4224 and is located on the upper side of the conveyor belt of the third conveyor belt mechanism 421. Several rotating shafts 4222 are vertically rotatably installed inside the guide frame 4221. The guide belt 4223 is vertically tensioned outside the rotating shaft 4222. One end of the guide belt 4223 near the light source gripping mechanism is set horizontally with the movement direction of the third conveyor belt mechanism 421, and the other end is inclined towards the outside of the third conveyor belt mechanism 421.

[0065] Specifically, a fourth electric cylinder 4241 is fixedly installed on both sides of the third conveyor belt mechanism 421 via a bracket 424. The fourth electric cylinders 4241 on both sides are staggered, and a push plate 4242 is fixedly installed at the top of the extended end of the fourth electric cylinder 4241.

[0066] The light source module 12 is transported by the third conveyor belt mechanism 421. When it reaches the light source guiding mechanism, the staggered fourth electric cylinder 4241 and its push plate 4242 reciprocate, which can act on the side of the light source module 12, correct the tilted light source module 12 and push it to the middle position of the third conveyor belt mechanism 421, and make the length direction of the light source module 12 the same as the movement direction of the third conveyor belt mechanism 421. Then, when passing the guide belt 4223, the symmetrically arranged third electric cylinder 4224 drives the rotating guide belt 4223 on the guide frame 4221. The guide belt 4223 acts on both sides of the light source module 12, so that the light source module 12 moves to the gripping station 4211 after being kept in the middle position on the conveyor belt. Then, the light source limiting mechanism 423 stops the light source module 12, so that the electric gripper 413 can hold it.

[0067] like Figure 8 , Figure 10 As shown, in this embodiment, a plurality of horizontally arranged rollers 4212 are rotatably arranged at one end of the third conveyor belt mechanism 421 near the light source gripping mechanism. The axial direction of the rollers 4212 is perpendicular to the movement direction of the third conveyor belt mechanism 421. The upper height of the rollers 4212 is the same as or slightly lower than the height of the conveyor belt surface of the third conveyor belt mechanism 421. There are gripping stations 4211 between the rollers 4212.

[0068] Specifically, the light source limiting mechanism includes a light source limiting plate 4231, an adjusting bracket 4232, and an adjusting rod 4233. An adjusting seat 4234 is fixedly installed below the third conveyor belt mechanism 421. The adjusting rod 4233 is movably disposed within the adjusting seat 4234. The moving direction of the adjusting seat 4234 is parallel to the moving direction of the third conveyor belt mechanism 421. One end of the adjusting rod 4233 extends beyond the end of the third conveyor belt mechanism 421. The adjusting rod 4233 has threads, and nuts 42 are screwed onto the adjusting rods 4233 on both sides of the adjusting seat 4234. 35. The distance by which one end of the adjusting rod 4233 extends beyond the third conveyor belt mechanism 421 is changed by the nut 4235. The adjusting bracket 4232 is vertically fixedly installed at the end of the adjusting rod 4233 away from the third conveyor belt mechanism 421, and the upper end has a horizontal bend towards the light source module 12. The light source limiting plate 4231 is fixedly installed at the top of the adjusting bracket 4232. A guide rod 4240 is fixedly connected to the adjusting bracket 4232. The guide rod 4240 and the adjusting rod 4233 are arranged in parallel and are inserted and slidably fitted in the adjusting seat 4234.

[0069] By using the light source limiting plate 4231, the light source module 12 can be stopped moving above the gripping station 4211, which makes it easier for the clamping frame 412 to grip the middle of the light source module 12. It can also be easily moved between the angle adjustment blocks 132 after clamping, improving the assembly accuracy. By using the adjusting rod 4233, the position of the light source limiting plate 4231 can be changed, thereby adapting to different models of light source modules 12, so that the middle of different models of light source modules 12 is always on the gripping station 4211.

[0070] like Figure 6 As shown, in this embodiment, the light source gripping mechanism includes an electric slide table 411, a second electric cylinder 412, an electric gripper 413, and a gripping frame 414. The electric slide table 411 is fixedly installed on the assembly table 1 via a support frame 415, with one end located above the placement table 321 and the other end located above the gripping station 4211. A mounting plate 4112 is fixedly installed on the slide table 411. The second electric cylinder 412 is vertically installed on the mounting plate 4112, and the actuating end of the second electric cylinder 412 is installed through the mounting plate 4112. The plate 4112 is set downwards. The top of the actuating end of the second electric cylinder 412 is fixedly connected to the connecting plate 4122. The electric gripper 413 is fixedly installed on the connecting plate 4122, and the gripper of the electric gripper 413 is set downwards. The clamping frame 414 is set in pairs, and the upper end is fixedly installed on the gripper of the electric gripper 413 respectively. The guide post 4123 is vertically set on the upper side of the connecting plate 4122. The mounting plate 4112 is equipped with a linear bearing, and the guide post 4123 slides up and down in the linear bearing.

[0071] Specifically, the lower end of the clamping frame 414 is bent inward to form a light source support surface. This support surface ensures the light source module 12 remains horizontal during clamping. Based on the relative position of the light source module 12 and the light source mounting base 13, a height limiting mechanism is required on the outer side of the clamping frame 414. This height limiting mechanism further ensures that the axes of the mounting holes of the light source module 12 and the angle adjustment block 132 are collinear. The height limiting mechanism includes a height limiting plate 4161 and a height limiting post 4162, with the height limiting post 4162 horizontally fixed. On the outside of the clamping frame 414, the height limiting plate 4161 is fitted to the clamping frame 414, and its lower end is lower than the lower end of the clamping frame 414. During assembly, the lower end of the height limiting plate 4161 contacts and engages with the upper surface of the light source mounting base 13. The height limiting plate 4161 has a height adjustment groove 4163, and the height limiting post 4162 is fitted and slidably arranged in the height adjustment groove 4163. A nut is screwed onto one end of the height limiting post 4162 located outside the height adjustment groove 4163, and the height limiting plate 4161 is fixed by the nut.

[0072] like Figures 1-2 As shown, after the mounting holes of the light source module 12 and the mounting holes of the angle adjustment block 132 are collinear, the locking mechanism can be activated to lock the light source module 12 between the angle adjustment blocks 132. After the light source module 12 on all four sides is assembled, the gripping part 314 grips the assembled light source mounting base 13, and the electric rotary table 311 rotates 90 degrees. At this time, the assembled multi-angle light source is above the unloading station 5. The unloading station 5 has a fourth conveyor belt mechanism 51 and an unloading mechanism 52.

[0073] Specifically, the fourth conveyor belt mechanism 51 is spaced apart, with the interval width being less than the width of the light source mounting base 13, and is connected by a synchronous shaft 512. The unloading mechanism is located between the fourth conveyor belt mechanisms 51. The unloading mechanism includes a fifth electric cylinder 521 and an unloading table 522. The fixed end of the fifth electric cylinder 521 is fixedly installed between the fourth conveyor belt mechanisms 51. The unloading table 522 is U-shaped, with a support plate bent outward at the upper end. The middle part of the lower end of the unloading table 522 is fixedly connected to the top of the actuating end of the fifth electric cylinder 521. When the first electric cylinder 312 moves downward, the lower side of the light source mounting base 13 is supported by the support plate. After the electric rotating gripper 3141 is released, the fifth electric cylinder 521 starts, causing the unloading table 522 to move downward with the actuating end, so that the lower side of the light source mounting base 13 is supported by the fourth conveyor belt mechanism 51, and then sent to the next process by the fourth conveyor belt mechanism 51.

[0074] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
