The top end of the limiting column 323 is 2-4 mm higher than the upper end plane 3213 of the placing table 321. The placing table 321 is further provided with an avoiding groove 3214 for preventing interference when the clamping plate 31422 rotates. After the light source mounting base 13 is transported to above the placing table 321, the first electric cylinder 312 is lowered to place the light source mounting base 13 on the placing table 321. Then the clamping plate 31422 is loosened. The four limiting columns 323 on the four-jaw positioning chuck 322 clamp the light source mounting base 13 at the same time to fix the position of the light source mounting base 13. The angle adjusting block 132 assembly hole 1321 reaches the position of the locking screw. When the light source module 12 reaches between the angle adjusting blocks 132, the locking screw mechanism is used to provide the screw and lock the light source module 12 between the angle adjusting blocks 132.

[0040] Specifically, the clamping end of the electric rotating clamp jaw 3141 can also rotate. After the light source module 12 on one side is assembled between the angle adjusting blocks 132, the four-jaw positioning chuck 322 is released, the electric rotating clamp jaw 3141 clamps the light source mounting base 13 again, then performs a 90-degree rotation, the clamping plate 31422 is released again after the rotation, the four-jaw positioning chuck 322 is clamped again, and then the light source module 12 is locked by using the lock screw mechanism again. After rotating three times, the four light source modules 12 are locked. As Figure 6 And Figure 9As shown, in the embodiment, the screw locking mechanism is symmetrically installed on the assembling table 1 and located on both sides of the placing table 321, including the locking mechanism 331 and the driving mechanism 332, the locking mechanism 331 has four and is symmetrically arranged in pairs on both sides of the placing table 321, two groups of locking mechanisms 332 are arranged, and one group of driving mechanisms 332 can drive two groups of locking mechanisms 331 at the same time to lock two light source modules 12 on the light source mounting base 13 at the same time.

Through the action of the linear bearing, the second sliding rail and the second sliding block, the feeding table 3312 moves on one side of the fixed table 3311, so that the feeding table 3312 is close to the mounting hole position of the light source mounting base 13 when the light source mounting base 13 is limited by the limiting column 323. The fixed table 3311 and the feeding table 3312 are both provided with through holes, and the through holes on the fixed table 3311 and the through holes on the feeding table 3312 are coaxially arranged one by one.

When the second motor 3321 outputs, the protruding shafts on both sides can have different rotation directions through the gear reversing device 3322, and the first gears 3301 on both sides of the placement table can rotate in opposite directions under the action of the gear transmission part, so that the four locking positions of the two light source modules are simultaneously locked by screws.

[0048] In the embodiment, the locking mechanisms 331 on the same side are connected through the synchronous pulley mechanism 333; the synchronous pulley mechanism is used to reduce the interference between the four-jaw positioning chuck and the locking mechanism.

[0049] Specifically, in the locking mechanisms 331 on the same side, the synchronous pulley mechanism 333 is arranged between the rotating shafts for installing the first gears 3301, and when the driving part 332 drives the nearest first gear 3301 to rotate, the other first gear 3301 on the same side rotates synchronously.

[0050] As shown in Figure 9 In the embodiment, in order to facilitate the two feeding tables 3312 on the same side to approach the angle adjusting block 132 at the same time, the screw machine chuck 3305 reaches the locking screw position of the angle adjusting block 132, the feeding tables 3312 are provided with clamping grooves at the lower sides, the same limiting plate 3333 is clamped in the clamping grooves of the two feeding tables 3312, the limiting column 323 is provided with a plug-in groove, and the middle part of the limiting plate 3333 is plug-in matched in the plug-in groove 3231 of the limiting column 323. When the four-jaw positioning chuck 322 limits the light source mounting base 13, the screw machine chuck 3305 can approach the angle adjusting block 132 at the same time, and the light source module 12 is installed on the angle adjusting block 132 by the cooperation of the screw and the shaft 3317.

[0051] As shown in Figure 2 In the embodiment, the light source module 12 is conveyed to the waiting grabbing work station on one side of the assembly table 1 through the light source conveying assembly 4, and then conveyed to the assembly work station 11 on the assembly table through the light source grabbing mechanism.

[0052] As shown in Figure 6 , Figure 10 , Figure 11As shown, specifically, the light source conveying assembly 4 comprises a third conveying belt mechanism 421, a light source guiding mechanism and a light source limiting mechanism. The third conveying belt mechanism 421 is located on the side of the assembling table 1 away from the first conveying belt mechanism 21.

The light source guiding mechanism is symmetrically arranged on both sides of the third conveying belt mechanism 421 and comprises a guiding frame 4221, a rotating shaft 4222, a guiding belt 4223 and a third electric cylinder 4224. The third electric cylinder 4224 is horizontally fixedly installed on the third conveying belt mechanism 421 through a support 424. The extending end of the third electric cylinder 4224 is arranged towards the third conveying belt mechanism 421. The guiding frame 4221 is fixedly installed at the top end of the extending end of the third electric cylinder 4224 and is located on the upper side of the conveying belt of the third conveying belt mechanism 421. The rotating shaft 4222 has a plurality of rotating shafts and is vertically rotatably installed in the guiding frame 4221. The guiding belt 4223 is vertically tensioned outside the rotating shaft 4222. One end of the guiding belt 4223 close to the light source grabbing mechanism is arranged horizontally with respect to the movement direction of the third conveying belt mechanism 421. The other end is inclined towards the outside of the third conveying belt mechanism 421. Specifically, fourth electric cylinders 4241 are also fixedly installed on both sides of the third conveying belt mechanism 421 through the support 424. The fourth electric cylinders 4241 on both sides are staggered. The top end of the extending end of the fourth electric cylinder 4241 is fixedly provided with a push plate 4242. The light source module 12 is conveyed by the third conveying belt mechanism 421. When the light source module 12 reaches the light source guiding mechanism, the fourth electric cylinders 4241 and the push plates 4242 staggered thereon reciprocate and can act on the side surface of the light source module 12. The inclined light source module 12 is corrected and pushed to the middle position of the third conveying belt mechanism 421. The length direction of the light source module 12 is the same as the movement direction of the third conveying belt mechanism 421. Then, when the light source module 12 passes through the guiding belt 4223, the third electric cylinders 4224 symmetrically arranged thereon drive the guiding belt 4223 rotatably arranged on the guiding frame 4221 at the same time. The guiding belt 4223 acts on both sides of the light source module 12. The light source module 12 moves to the grabbing station 4211 after being kept in the middle position of the conveying belt. Then, the light source module 12 is stopped by the light source limiting mechanism 423, so as to be clamped by the electric clamping jaw 413. As shown in Figure 8 , Figure 10 In this embodiment, a plurality of horizontally arranged rollers 4212 are rotatably arranged at one end of the third conveying belt mechanism 421 close to the light source grabbing mechanism.

The moving direction of the adjusting seat 4234 is parallel to the moving direction of the third conveying belt mechanism 421. One end of the adjusting rod 4233 is beyond the end of the third conveying belt mechanism 421. The adjusting rod 4233 is threaded. Nuts 4235 are respectively screwed on the adjusting rod 4233 on both sides of the adjusting seat 4234. The distance between the one end of the adjusting rod 4233 and the third conveying belt mechanism 421 is changed by the nuts 4235. The adjusting support 4232 is vertically and fixedly installed at the one end of the adjusting rod 4233 away from the third conveying belt mechanism 421. The upper end of the adjusting support 4232 is horizontally bent towards the light source module 12. The light source limiting plate 4231 is fixedly installed at the top end of the adjusting support 4232. A guide rod 4240 is fixedly connected to the adjusting support 4232. The guide rod 4240 is parallel to the adjusting rod 4233 and is slidingly connected to the adjusting seat 4234. The light source limiting plate 4231 can stop the light source module 12 from moving above the grabbing station 4211, so that the clamping frame 412 can grab the middle part of the light source module 12. The light source module 12 can be moved to the angle adjusting block 132 after being clamped, so as to improve the assembly precision. The adjusting rod 4233 can change the position of the light source limiting plate 4231, so as to adapt to different models of the light source module 12.

As shown in FIG. 13, Figure 6 In this embodiment, the light source grabbing mechanism includes an electric sliding table 411, a second electric cylinder 412, an electric clamp jaw 413, and a clamping frame 414.

An installation plate 4112 is fixedly installed on the sliding table of the electric sliding table 411. The second electric cylinder 412 is vertically installed on the installation plate 4112. The action end of the second electric cylinder 412 penetrates through the installation plate 4112 and is arranged downward. The top end of the action end of the second electric cylinder 412 is fixedly connected to a connecting plate 4122. The electric clamp jaw 413 is fixedly installed on the connecting plate 4122. The clamping jaw of the electric clamp jaw 413 is arranged downward. The clamping frame 414 is arranged in pairs. The upper ends are respectively fixedly installed on the clamping jaws of the electric clamp jaw 413. A guide column 4123 is vertically arranged on the upper side of the connecting plate 4122. A linear bearing is installed on the installation plate 4112. The guide column 4123 is slidingly arranged up and down in the linear bearing. Specifically, the lower end of the clamping frame 414 is inwardly bent to form a light source support surface, which can ensure the light source module 12 to be horizontal in clamping. According to the relative position of the light source module 12 and the light source mounting base 13, a height limiting mechanism needs to be arranged on the outer side of the clamping frame 414 to further make the axis of the mounting hole of the light source module 12 and the mounting hole of the angle adjusting block 132 collinear. The height limiting mechanism includes a height limiting plate 4161 and a height limiting column 4162. The height limiting column 4162 is horizontally fixedly installed on the outer side of the clamping frame 414. The height limiting plate 4161 is arranged in close contact with the clamping frame 414, and the lower end is lower than the lower end of the clamping frame 414.

One end of the height limiting column 4162 located outside the height adjusting groove 4163 is screwed with a nut to fix the height limiting plate 4161. As shown in Figures 1-2 After the axis of the mounting hole of the light source module 12 and the mounting hole of the angle adjusting block 132 is collinear, the locking mechanism can be started to lock the light source module 12 between the angle adjusting blocks 132. After the light source module 12 on four sides is assembled, the grabbing part 314 grabs the assembled light source mounting base 13. The electric rotary table 311 rotates by 90 degrees. At this time, the multi-angle light source assembled is above the unloading station 5. The unloading station 5 has a fourth conveying belt mechanism 51 and an unloading mechanism 52.

[0054] Specifically, the fourth conveying belt mechanism 51 is arranged at intervals, the interval width is less than the width of the light source mounting base 13, and is connected through a synchronous shaft 512. The unloading mechanism is located between the fourth conveying belt mechanism 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 conveying belt mechanism 51. The unloading table 522 is arranged in a U shape and has a support plate bent outwardly at the upper end. The lower end of the unloading table 522 is fixedly connected with the top end of the moving 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 rotary jaw 3141 is loosened, the fifth electric cylinder 521 is started to move the unloading table 522 downward with the moving end, so that the lower side of the light source mounting base 13 is supported by the fourth conveying belt mechanism 51, and then is sent to the next process by the fourth conveying belt mechanism 51.
