Detailed implementation manners

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0037] As Figures 1 to 11 shown, a lighting module light source board assembly device includes a bottom plate 1. Above the bottom plate 1, a first rotating ring 2 and a second rotating ring 3 are provided. Four first placement grooves 4 and four second placement grooves 5 are respectively formed in the first rotating ring 2 and the second rotating ring 3 along the circumferential direction. The second rotating ring 3 is located at the top of the first rotating ring 2. One of the first placement grooves 4 communicates with the corresponding second placement groove 5;

[0038] Two rotating frames 6 are fixedly connected to the top of the bottom plate 1. The two rotating frames 6 are respectively rotatably connected to the inside of the first rotating ring 2 and the second rotating ring 3. First support mechanisms are connected to the inside of the first placement grooves 4, and second support mechanisms are connected to the inside of the second placement grooves 5. A light source board assembly mechanism and a pressing assembly mechanism are connected to the bottom plate 1. The light source board assembly mechanism includes a placement frame 26. The placement frame 26 is fixedly connected to the bottom plate 1 and is located at the top of the first rotating ring 2. Rectangular grooves 27 are formed at the bottoms of both sides of the placement frame 26 (as Figure 11As shown in the figure, two mounting brackets 28 are fixedly connected inside the rectangular groove 27. A rotating shaft 29 is rotatably connected between two adjacent mounting brackets 28. A guiding roller 30 is fixedly connected to the rotating shaft 29. The side surface of the guiding roller 30 extends into the corresponding rectangular groove 27 and is flush with the inner side of the placing frame 26. Two arc-shaped support bars 31 are fixedly connected to the guiding roller 30. The two arc-shaped support bars 31 are arranged oppositely and have a height difference. An intermittent rotation mechanism is connected between the first rotating ring 2 and the second rotating ring 3. During operation, in the prior art, when assembling a light source board, a manipulator is usually used to clamp the parts and assemble them in sequence. When continuously processing multiple lighting modules, the assembly equipment can only assemble the next lighting module after completing the assembly of a single lighting module, thereby reducing the actual assembly efficiency and affecting the continuous processing speed of the lighting module. Moreover, when assembling the light source board, clamping, moving, and releasing the clamping after docking are required through the manipulator for clamping and assembling, resulting in a cumbersome assembly process and affecting the assembly efficiency of the light source board. This technical solution can solve the above problems. The specific working method is as follows: Place the lamp holder and the lamp shade in the mutually separated first placing groove 4 and second placing groove 5 respectively for limiting, and support them through the first support mechanism and the second support mechanism respectively. Under the action of the intermittent rotation mechanism, the first rotating ring 2 and the second rotating ring 3 rotate intermittently synchronously by 90 degrees. After the lamp holder in the first placing groove 4 rotates by 90 degrees, the light source board is assembled into the corresponding lamp holder through the action of the light source board assembly mechanism, and then continues to rotate by 90 degrees through the action of the intermittent rotation mechanism and is located at the bottom of the corresponding second placing groove 5. Then, through the action of the pressing and assembling mechanism, the lamp shade in the second placing groove 5 is pressed and snap-connected to the top of the corresponding lamp holder, and during the pressing process, the support of the second support mechanism for the second placing groove 5 is released, so that the lamp shade smoothly enters the first placing groove 4 through the communication part of the second placing groove 5 and the first placing groove 4 and completes the assembly. Continuously place the lamp shade and the lamp holder in the corresponding first placing groove 4 and second placing groove 5, and through the synchronous intermittent rotation of the first rotating ring 2 and the second rotating ring 3, the feeding of the lamp shade and the lamp holder, the assembly of the light source board, and the snap-connection assembly of the lamp shade and the lamp holder can be operated synchronously, thereby improving the assembly efficiency of the lighting module and the continuous processing speed of the lighting module;

[0039] Place multiple light source boards inside the placement frame 26 and support them through the arc-shaped support bars 31 below the guiding rollers 30. Since multiple LED lamp beads are installed on the top of each light source board, when stacked, there is a spacing between the sides of two adjacent light source boards. The thickness of the arc-shaped support bar 31 is the same as the height of the side of the light source board, and the height difference between two adjacent arc-shaped support bars 31 is the same as the height of the side of the light source board. Rotate 180 degrees through the rotating shaft 29 to synchronously rotate the guiding roller 30. The arc-shaped support bar 31 below the guiding roller 30 rotates to the outside of the placement frame 26 and loses the support for the bottommost light source board, causing the bottommost light source board in the placement frame 26 to drop to the first placement slot 4 after losing its limit and be vertically assembled with the corresponding lamp socket. The arc-shaped support bar 31 above the guiding roller 30 synchronously rotates towards the inside of the placement frame 26, thereby supporting the bottom of the second-to-bottom light source board inside the placement frame 26, and continuing to support the remaining light source boards after the bottommost light source board in the placement frame 26 drops. Then, continue to rotate 180 degrees through the rotating shaft 29 and return to the initial position, causing the arc-shaped support bar 31 above the guiding roller 30 to rotate to the outside of the placement frame 26 and release the support for the remaining light source boards, causing the remaining light source boards inside the placement frame 26 to move downward synchronously and continue to be supported by the arc-shaped support bar 31 below the guiding roller 30. Thus, when the rotating shaft 29 drives the guiding roller 30 to rotate one circle, the bottommost light source board in the placement frame 26 is assembled to the top of the corresponding lamp socket, and the remaining light source boards are moved and continuously supported, thereby realizing the automatic assembly of the light source boards. After the guiding roller 30 rotates one circle, the light source boards are automatically assembled by the action of gravity, reducing the operation steps in the assembly process of the light source boards and improving the assembly efficiency of the light source boards.

[0040] As a further embodiment of the present invention, the first support mechanism includes two first movable slots 7 (as Figure 7 shown), the two first movable slots 7 are respectively opened at the bottoms on both sides of the first placement slot 4. First support plates 8 are slidably connected inside the first movable slots 7, and an active telescopic mechanism is connected to the first support plates 8; during operation, one ends of the two first support plates 8 extend into the first placement slot 4 along the first movable slots 7. When the lamp socket is placed inside the first placement slot 4, the bottom of the lamp socket can be supported by the two first support plates 8. After the lamp socket and the lamp shade are snap-fitted and rotated 90 degrees by the action of the intermittent rotation mechanism, the two first support plates 8 are completely moved into the corresponding first movable slots 7 by the action of the active telescopic mechanism, thereby releasing the support for the bottom of the lamp socket, and enabling the snap-fitted lamp socket and lamp shade to be automatically unloaded along the bottom of the first placement slot 4.

[0041] As a further embodiment of the present invention, the active telescopic mechanism includes two guiding ring rails 9 (as Figure 4 and Figure 5As shown in the figure, the two guide ring rails 9 are fixedly connected to the base plate 1 and are located at the bottom of the first rotating ring 2. The two guide ring rails 9 are coaxially arranged. The guide ring rails 9 include an arc segment 901 and a contraction segment 902. The two contraction segments 902 are in opposite directions. The bottom of the first support plate 8 is fixedly connected with a circular pin 10, and the circular pins 10 are respectively located inside the corresponding guide ring rails 9. During operation, when the circular pin 10 is located inside the arc segment 901 of the guide ring rail 9, one end of the first support plate 8 extends along the first movable groove 7 to the inside of the first placement groove 4 and supports the bottom of the lamp holder. When the circular pin 10 moves along the arc segment 901 to the contraction segment 902, the first support plate 8 moves along the first movable groove 7, and when the circular pin 10 moves to the center of the contraction segment 902, the first support plate 8 is completely moved to the inside of the first movable groove 7, thereby releasing the support of the bottom of the lamp holder and unloading.

[0042] As a further embodiment of the present invention, the second supporting mechanism includes two second movable grooves 11, and the two second movable grooves 11 are respectively opened at the bottom of both sides of the second placement groove 5 (such as Figure 2 and Figure 9 As shown in the figure, two through grooves 12 are provided on the second rotating ring 3, and the second support plates 13 are slidably connected inside the second movable grooves 11, and wedge blocks 14 are arranged inside the through grooves 12, and two light rods 15 are slidably inserted on the wedge blocks 14, and the light rods 15 are fixedly connected inside the corresponding through grooves 12, and springs 16 are sleeved on the light rods 15, and the springs 16 are fixedly connected between the corresponding wedge blocks 14 and one side of the through grooves 12, and two fixing bars 17 are fixedly connected to one side of the wedge blocks 14, and one end of the fixing bars 17 extends to the corresponding second movable grooves 11 and is fixedly connected to the corresponding second support plates 13; when working, the wedge blocks 14 are squeezed by the elastic stretching action of the springs 16, so that the wedge blocks 14 contact with the side of the through grooves 12 close to the second movable grooves 11, and the wedge blocks 14 and the second support plates 13 are fixed by the fixing bars 17, so that one end of the second support plates 13 is located inside the second placement groove 5 and supports the bottom of the lampshade.

[0043] As a further embodiment of the present invention, the pressing assembly mechanism includes a U-shaped frame 18, which is fixedly mounted on the bottom plate 1, a connecting plate 19 is arranged inside the U-shaped frame 18, a plurality of limit pins 20 are fixedly connected to the top of the connecting plate 19, and the limit pins 20 are slidably inserted on the U-shaped frame 18, a hydraulic cylinder 21 is fixedly mounted on the top of the U-shaped frame 18, a piston shaft of the hydraulic cylinder 21 passes through the U-shaped frame 18 and extends to the inside of the U-shaped frame 18 and is fixedly connected to the top of the connecting plate 19, a plurality of pressing rods 22 are fixedly connected to the bottom of the connecting plate 19 along the circumferential direction, and extrusion strips 23 are fixedly connected to both sides of the bottom of the connecting plate 19, and four sets of make way grooves 24 (such as Figure 6As shown in the figure, the number of each group of relief grooves 24 is two, and the first placement groove 4 is located between the two relief grooves 24 in the same group; during operation, when the lamp holder and the light source board are assembled and rotated to the bottom of the corresponding second placement groove 5, and the lamp shade inside the second placement groove 5 is located above the lamp holder and the light source board, the piston shaft of the hydraulic cylinder 21 moves downward to drive the connecting plate 19 to move synchronously. The limit pin 20 on the top of the connecting plate 19 moves synchronously along the sliding insertion part of the U-shaped frame 18, and limits the movement of the connecting plate 19. The connecting plate 19 drives the extrusion strip 23 to move downward and contact and squeeze the corresponding wedge block 14, and through the inclined surface on the top of the wedge block 14, the wedge block 14 moves and gives way along the through groove 12, so that the wedge block 14 moves along the sliding insertion part of the optical rod 15 and squeezes the spring 16 to generate a compressive deformation, and drives the fixed strip 17 and the second support plate 13 to move and give way, so that the second support plate 13 completely moves into the corresponding second movable groove 11 and releases the limit on the bottom of the lamp shade. Then, under the action of the hydraulic cylinder 21, the connecting plate 19 continues to move downward, so that the plurality of pressing rods 22 at the bottom of the connecting plate 19 press the top of the lamp shade, and push and squeeze the lamp shade from the inside of the second placement groove 5 into the corresponding first placement groove 4, and snap-fit the lamp shade onto the top of the lamp holder. At the same time, the extrusion strip 23 moves downward from between the corresponding two fixed strips 17 and is inserted into the corresponding relief groove 24. After the assembly of the lamp shade and the lamp holder is completed, the piston shaft of the hydraulic cylinder 21 moves in the reverse direction and drives the connecting plate 19 to return to the initial position. The extrusion strip 23 rises synchronously and returns. After the wedge block 14 loses the extrusion of the extrusion strip 23, it returns to the initial position through the elastic stretching action of the spring 16, and one end of the second support plate 13 moves back into the second placement groove 5 again, so that the second placement groove 5 continues to support the lamp shade during the subsequent rotational processing.

[0044] As a further embodiment of the present invention, a pressing head 25 is fixedly connected to the bottom end of each pressing rod 22, and the pressing head 25 is made of rubber material; during operation, during the downward movement of the pressing rod 22, the pressing head 25 at the bottom end of the pressing rod 22 contacts the top of the lamp shade and presses the lamp shade to move. The flexible rubber material of the pressing head 25 reduces the rigid contact at the contact position, thereby preventing scratches on the surface of the lamp shade.

[0045] As a further embodiment of the present invention, a first motor 32 is fixedly installed on both sides of the placement frame 26, and the output shafts of the first motors 32 are respectively fixedly connected to the tops of the corresponding rotating shafts 29; during operation, the output shafts of the two first motors 32 rotate 180 degrees, thereby driving the rotating shafts 29 to rotate, so as to drive the rotating shafts 29 to rotate.

[0046] As a further embodiment of the present invention, two limiting bars 33 are provided on both sides inside the placement frame 26. Two sliding grooves 34 are opened on both sides of the placement frame 26. A sliding bar 35 is slidably connected inside each sliding groove 34. The sliding bar 35 is fixedly connected to the corresponding limiting bar 33. Two U-shaped bars 36 are provided on both sides of the placement frame 26. Both ends of the U-shaped bar 36 are fixedly connected to the two sliding bars 35 on the same side. An arc-shaped pin 37 is fixedly connected inside the U-shaped bar 36. Inclined surface annular grooves 38 are opened on the surfaces of the guiding rollers 30. The arc-shaped ends of the arc-shaped pins 37 are respectively located inside the corresponding inclined surface annular grooves 38. During operation, through the limiting of the limiting bars 33 inside the placement frame 26 and the grooves on the side surface of the light source board, when the guiding rollers 30 rotate 180 degrees and the lowermost light source board moves downward for assembly, through the guiding and limiting effect of the inclined surface annular grooves 38 on the arc-shaped pins 37, the arc-shaped pins 37 move downward synchronously, and drive the U-shaped bars 36 to move downward synchronously, so that the sliding bars 35 slide along the sliding grooves 34 and drive the limiting bars 33 to move into the first placement groove 4, so that during the process that the light source board drops downward and loses the limitation of the placement frame 26, the limiting bars 33 continue to limit the light source board, preventing the light source board from causing position deviation during the dropping process, ensuring the accuracy of the assembly position of the light source board and the lamp holder, and after the guiding rollers 30 continue to rotate 180 degrees and return to the initial position, the arc-shaped ends of the arc-shaped pins 37 are re-located at the initial positions of the inclined surface annular grooves 38, so that the limiting bars 33 move upward and return to the initial position, thereby preventing the limiting bars 33 from blocking the rotation of the first rotating ring 2 and ensuring the normal rotation of the first rotating ring 2.

[0047] As a further embodiment of the present invention, communication grooves 39 (as Figure 10 shown) are opened on both sides of the placement frame 26. The two communication grooves 39 are arranged oppositely. During operation, by opening the communication grooves 39 on both sides of the placement frame 26, when the staff replenishes and places the light source boards, the staff can move and place the stacked light source boards along the communication grooves 39, so that the light source boards can move downward inside the placement frame 26 on the premise of being grabbed, improving the stability and safety of placement.

[0048] As a further embodiment of the present invention, the intermittent rotation mechanism includes a fixed frame 40 (as Figure 3As shown in the figure, the fixing frame 40 is fixedly connected to the bottom plate 1. A second motor 41 is fixedly installed inside the fixing frame 40. The output shaft of the second motor 41 penetrates the fixing frame 40 and extends above the fixing frame 40 and is fixedly connected to a gear 42. Outer tooth rings 43 are fixedly connected to the sides of the first rotating ring 2 and the second rotating ring 3. The first rotating ring 2 and the second rotating ring 3 have the same diameter, and both outer tooth rings 43 are engaged with the gear 42. During operation, the output shaft of the second motor 41 rotates to drive the gear 42 to rotate, and through the meshing action of the gear 42 and the two outer tooth rings 43, the first rotating ring 2 and the second rotating ring 3 with the same diameter rotate in the same direction and maintain the same rotation speed.

[0049] Working principle of the present invention:

[0050] The lamp holder and the lamp shade are respectively placed inside the mutually separated first placement groove 4 and second placement groove 5 for positioning, and are respectively supported by the first support mechanism and the second support mechanism. Through the action of the intermittent rotation mechanism, the first rotating ring 2 and the second rotating ring 3 synchronously perform intermittent rotation by 90 degrees. After the lamp holder inside the first placement groove 4 rotates by 90 degrees, the light source board is assembled into the corresponding lamp holder through the action of the light source board assembly mechanism, and then continues to rotate by 90 degrees through the action of the intermittent rotation mechanism and is located at the bottom of the corresponding second placement groove 5. Then, through the action of the pressing and assembling mechanism, the lamp shade inside the second placement groove 5 is pressed and snap-connected to the top of the corresponding lamp holder, and during the pressing process, the support of the second support mechanism for the inside of the second placement groove 5 is released, so that the lamp shade smoothly enters the inside of the first placement groove 4 along the communication part of the second placement groove 5 and the first placement groove 4 and completes the assembly.
