[0032] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] See also Figure 1-Figure 4 The frame 1 of the automatic assembly device for LED lamps is an installation platform, and a rotating seat is provided in the middle thereof. The rotating seat is used to place the lamp holder and can drive the lamp holder to be transferred. When the lamp holder is transferred to the position of the gluing mechanism, the rotating seat stops, and the gluing mechanism performs a gluing operation on the lamp holder. Then the rotating seat rotates one station to move the next base to be glued to the bottom of the gluing mechanism. The glued lamp holder is moved to one side of the grabbing and feeding mechanism. The other side of the grabbing and feeding mechanism is a conveying mechanism. The grabbing and feeding mechanism grabs and transfers the lampshade on the conveying mechanism, and moves the lampshade to the top of the glued lamp holder. Then the lampshade and the lamp holder are pressed and bonded. The bonded LED lamp is grabbed and moved by the unloading mechanism to transfer the LED lamp to a material box for receiving materials.

[0034] The grabbing bracket 2 of the grabbing and feeding mechanism is the installation body, which is fixedly connected to the frame 1. The upper end of the grabbing bracket 2 is a fixedly installed cross brace 3. The groove in the middle of the cross brace 3 is used for the front material picking cylinder 5 and the rear material picking cylinder 6 installed on the material picking base 4 to move. The material picking base 4 is driven to move by the screw motor 8 installed on the cross brace 3 and the matching screw pair 9. The suction cup at the lower end of the front material picking cylinder 5 is connected to the corresponding air pump through a pipeline. When the air pump is pumping air, a negative pressure is formed in the suction cup, which can suck up the lampshade. When the first lampshade is sucked up, the material picking base 4 moves backward and moves the lampshade to the top of the lampshade support 58. The front material picking cylinder 5 drives the lampshade to move downward, so that the lampshade is stuck on the lampshade support 58. Then the front material picking cylinder 5 is reset, and the material picking base 4 moves forward, so that the front material picking The cylinder 5 moves to the top of the second lampshade. At the same time, the lampshade die head 7 installed at the end of the rear material-picking cylinder 6 is located above the lampshade support 58. The rear material-picking cylinder 6 moves down and clamps on the first lampshade to complete the clamping of the first lampshade. Then the front material-picking cylinder 5 and the rear material-picking cylinder 6 both move up, and at the same time drive one lampshade to move up. The material-picking base 4 moves, and the front material-picking cylinder 5 moves the second lampshade to the top of the lampshade support 58. The rear material-picking cylinder 6 drives the first lampshade to be moved to the top of the lampshade bonding station at the rear end. The front material-picking cylinder 5 and the rear material-picking cylinder 6 move down synchronously, and the front material-picking cylinder 5 places the lampshade it grabs on the lampshade support 58, and the rear material-picking cylinder 6 transfers the lampshade to the bonding station for bonding operation. This operation step is cycled to realize automatic loading and unloading of lampshades.

[0035] See also Figure 4 The lifting plate 10 is movably installed on the guide rail seat of the grabbing bracket 2 through a slider, and the lifting plate 10 is driven to move on the guide rail seat by the cylinder installed on the side wall of the cross brace plate 3, so that the support plate 11 installed on the lifting plate 10 is also lifted and moved synchronously. A clamping cylinder 13 is fixed on both sides of the support plate 11, and the clamping cylinder 13 can drive the semicircular clamping head 12 to move. The clamping head 12 and the support plate 11 are movably installed between the guide rail slider to provide a guide for the movement of the clamping head 12. After the lifting plate 10 moves down, the lamp holder on the rotating seat is extended into the through hole on the support plate 11, and then the clamping cylinder 13 is started to drive the clamping head 12 to move inward to clamp the lamp holder, so that the rear material-taking cylinder 6 drives the lampshade to move down. At this time, the lamp holder has been coated with glue, and the lampshade and lamp holder can be bonded.

[0036] See also Figure 5 and Figure 6The rotating motor 14 of the rotating seat and the angular reducer 15 connected thereto are fixed on the frame 1, and a turntable 16 is fixed on the output shaft of the angular reducer 15. The rotating motor 14 can drive the turntable 16 to rotate. There are multiple rotating supports 18 arranged evenly at intervals on the upper outer ring of the rotating disk 16. The groove in the rotating support 18 is used to place the lamp holder. There is a connecting shaft passing through the turntable 16 at the bottom of the rotating support 18. The connecting shaft and the turntable 16 are movably installed through a bearing. A contact wheel 19 is fixedly installed at the tail end of the connecting shaft. A rotating seat motor 20 is fixed on the frame 1 on one side of the turntable 16. The driving wheel 21 at the upper end of the rotating seat motor 20 can contact the contact wheel 19, and the driving wheel 21 is tangent to the contact wheel 19. Both the contact wheel 19 and the driving wheel 21 are made of rubber material, which can be deformed when in contact, to ensure that the rotating seat motor 20 can drive the rotating support 18 to rotate.

[0037] A plurality of turntable brackets 17 for supporting are also installed on the frame 1 , and a supporting roller is installed at the top of the turntable bracket 17 through an axis, and the supporting roller contacts the lower end of the turntable 16 to support the outer side of the turntable 16 .

[0038] See also Figure 7 and Figure 8 The glue coating bracket 22 of the glue coating mechanism is fixedly installed on the frame 1. The inner side of the glue coating bracket 22 is a concave structure, and the first screw rod 23 is movably installed at its upper and lower ends through bearings. The rear side of the glue coating lifting seat 24 is attached to the glue coating bracket 22. At the same time, the tail end of the glue coating lifting seat 24 has a screw sleeve arranged in the first screw rod 23. When the disc at the top of the first screw rod 23 is rotated, the glue coating lifting seat 24 can be driven to move up and down. There are two parallel guide rods 27 and a second screw rod 25 movably installed through a bearing between the two end plates of the glue coating lifting seat 24. The middle part of the push block 26 has an internal thread, which is sleeved in the second screw rod 25. When the disc at the tail end of the second screw rod 25 is rotated, the push block 26 can be driven to move forward and backward along the guide rod 27. At this time, the connecting rod 28 installed on the push block 26 can drive the glue coating cylinder 29 to move forward and backward, which is convenient for adjusting the glue coating head 31 installed at the lower end of the glue coating cylinder 29 to move forward and backward and up and down.

[0039] The gluing head 31 is installed in the arc-shaped installation groove on the gluing plate 30 by bolts, and the angle of the gluing head 31 can be adjusted. The gluing plate 30 is fixedly connected to the gluing cylinder 29 and can be lifted and lowered under the drive of the gluing cylinder 29.

[0040] When the gluing mechanism is working, first, according to the height and position of the lamp holder placed in the rotating support 18, the first screw 23 and the second screw 25 are adjusted to make the static height of the gluing head 31 slightly higher than the upper edge of the lamp holder. Through adjustment, the deflection angle of the gluing head 31 meets the gluing requirement. When the lamp holder is driven by the turntable 16 to be transferred to the gluing station, the gluing cylinder 29 is started to drive the gluing head 31 to move downward, and the rotating support 18 rotates, which can drive the lamp holder to rotate, and the upper end of the base can be glued in a circular shape.

[0041] See also Fig. 9 The purpose of the lamp holder clamping mechanism is to clamp and place the lamp holder placed in the rotating support 18. Because the lamp holder may be misaligned when placed, the groove in the rotating support 18 is matched with the shape of the lamp holder. The clamping cylinder 33 drives the pressure head to move downward, and the pressure head is pressed on the upper side of the lamp holder. The lamp holder is pressed down to fit with the rotating support 18, which is convenient for subsequent operations.

[0042] The lamp holder clamping mechanism includes a clamping bracket 32 ​​fixedly mounted on the frame 1 . The inner side of the clamping bracket 32 ​​is a concave structure, which is convenient for the turntable 16 to extend into, ensuring that the rotating support 18 installed on the turntable 16 is located below the clamping cylinder 33 .

[0043] See also Figure 10-13 The unloading bracket 34 of the unloading mechanism is fixed on the frame 1, and a horizontal plate 35 is fixed on the upper end of the unloading bracket 34. The driving motor 38 is fixed on the horizontal plate 35. At the same time, the driving shaft on the driving motor 38 is fixedly connected to a pulley in a pulley seat 36. Two consistent pulley seats 36 are installed on the horizontal plate 35. The two pulley seats 36 are equipped with pulleys through shafts. The belt 37 fixed with the unloading moving plate 39 is installed on the pulley of the pulley seat 36. When the driving motor 38 is working, the unloading moving plate 39 can be driven to move horizontally. 9 is equipped with a clamping head 43 for clamping the LED lamp, and the clamping head 43 is fixed on the adapter plate 42. Under the drive of the two-way clamping cylinder 41, the clamping head 43 moves inward to clamp the LED lamp. The two-way clamping cylinder 41 is fixed to the lower end of the unloading lifting cylinder 40. The unloading lifting cylinder 40 drives the two-way clamping cylinder 41 to move upward, and the LED lamp can be taken out from the rotating support 18. Then, driven by the driving motor 38, the LED lamp is driven to translate to the position of the unloading inclined plate. The two-way clamping cylinder 41 releases the clamping head 43 to complete the unloading operation of the LED lamp.

[0044] See also Fig.11 The transverse slide rail 44 installed on the transverse plate 35 cooperates with the slider on the rear side of the unloading movable plate 39 to provide a moving guide for the unloading movable plate 39, ensuring that the unloading movable plate 39 moves smoothly and facilitates the unloading operation.

[0045] See also Fig.10 and Fig.11 The vertical slide rail 45 on the unloading moving plate 39 is used in conjunction with the slider on the rear side of the cylinder positioning plate 46. The lower edge of the cylinder positioning plate 46 is fixedly connected to the two-way clamping cylinder 41.

[0047] A push plate 55 is fixed at the lower end of the downward pressure cylinder 54. A push plate guide rod 57 installed on the push plate 55 can pass through a guide sleeve in the middle of the connecting plate 53 to provide guidance for the push plate 55 to move up and down.

[0048] See also Figure 1 and Fig.14 The conveying mechanism is two mutually perpendicular conveying frames 47, each of which is composed of a corresponding motor, a pulley and a belt structure, and the belt at the upper end is used to convey the lampshade. A plurality of positioning seats 48 are fixed by bolts on both sides of the conveying frame 47, and a support rod 49 is inserted into the positioning seat 48. The relative height of the support rod 49 is adjustable. There is a damping sense between the support rod 49 and the positioning seat 48, and it will not fall due to its gravity. There is a mounting block at the top of the support rod 49, and a push rod 50 is inserted into the mounting block. There is also a damping sense between the push rod 50 and the mounting block, which can effectively prevent the push rod 50 from moving due to some small external force. A guide rod 52 is installed on the inner side of the push rod 50 through a transfer block 51. The guide rod 52 is formed into an arc shape at the position where the conveying frame 47 is connected. The lampshade can be naturally transferred between the two conveying frames 47.

[0049] The working principle of the present invention is as follows: When the automatic assembly device for LED lamps is working, the lampshade and the lamp holder are loaded by the conveying mechanism and the rotating seat respectively. The lampshade is conveyed by the conveying mechanism to the position of the grabbing and feeding mechanism, and is grabbed by the front picking cylinder 5 on the grabbing and feeding mechanism. The lampshade is then transferred to the lampshade support 58 for temporary storage. The rear picking cylinder 6 moves to the top of the lampshade support 58. The rear picking cylinder 6 can grab the lampshade and then move it to the gluing station.

[0050] While the lampshade is being transferred, the lamp holder is transported through the rotating seat and first moved to the position of the lamp holder pressing mechanism to completely press the lampshade into the rotating support 18. The lampshade is then moved to the position of the gluing mechanism, and the gluing mechanism performs gluing on the lamp holder. After gluing, the lamp holder is moved to the inner side of the grabbing and feeding mechanism. At this time, the cylinder on the grabbing and feeding mechanism drives the support plate 11 to move downward, and the clamping head 12 on the support plate 11 is sleeved on the outer side of the lampshade. The clamping cylinder 13 drives the clamping head 12 to clamp the lamp holder, and the rear feeding cylinder 6 drives the lampshade to move downward for pressing and pasting operations.

[0051] After the initial pressing, the support plate 11 is reset, and the turntable 16 drives the bonded LED lamp to continue to rotate and move it to the position of the unloading mechanism. The unloading mechanism is provided with a downward pressure cylinder 54 and a pressure block 56, which can perform a secondary pressing on the bonded LED lamp to ensure the effect of the bonding. At the same time, the LED lamp is clamped by the clamping head 43, and driven by the driving motor 38, the LED lamp is moved to the position of the unloading plate, and the LED lamp is slid into the collection box by sliding, completing the assembly operation of the LED lamp.
