[0019] The present invention discloses an LED light strip, which is assembled by an automatic LED light strip assembly device. The light board is plugged into a light strip base, a plurality of lamp beads are arranged on the light strip base, and an installation groove for gluing is opened on the outer side of each lamp bead, and the lens is installed in the installation groove.

[0020] The present invention also discloses a production method of an automatic assembly device for LED light strips, comprising the following steps:

[0021] S1: When working, place the base of the light strip at the end of the trough, place the light board between the two conveying components of the same conveying part, and place the light board between the auxiliary wheel and the conveying wheel;

[0022] S2: Control the driving motor to run, the output shaft of the driving motor drives the first rotating shaft to rotate, the first rotating shaft drives the conveying wheel to rotate, the conveying wheel cooperates with the auxiliary wheel to convey the light board, so that the light board moves to the bottom of the pushing and unloading mechanism;

[0023] S3: When the installation groove of the lamp board is placed directly below the annular seat, the hydraulic cylinder is controlled to work, and the piston rod of the hydraulic cylinder drives the pressure seat to move downward. When the pressure seat moves downward, the push seat is driven to move through the connecting rod and the connecting plate, so that the push seat leaves the connecting groove and moves to the side away from the discharge pipe. As the pressure seat continues to move upward, the baffle plate connected to the outside of the push seat no longer resists the preparation lens on the lower side of the barrel, and the preparation lens on the lower side of the barrel automatically falls under the action of its own gravity;

[0024] After the pressing seat moves downward, it contacts the unloading lens placed on the limit block at the lower side of the unloading tube. The unloading lens placed on the limit block moves downward under the force. The unloading lens presses the first inclined surface of the limit block, and the limit block avoids the downward movement of the unloading lens.

[0025] S4: When the pressure seat presses the limit block through the lens, the movement of the limit block drives the piston block to move in the pneumatic cavity through the connecting rod. The piston block squeezes the air in the pneumatic cavity and passes through the air outlet valve and the exhaust channel, and finally is discharged from the exhaust port. The exhausted air blows toward the installation groove on the lower lamp board to make the impurities in the installation groove fly away;

[0026] When the limit block moves, it presses the second inclined surface at the end of the moving rod. The moving rod is forced to drive the rubber seat downward. When the rubber seat does not abut against the inner wall of the conical groove, the glue in the conical groove will not be squeezed out from the liquid outlet nozzle. As the moving rod continues to move downward, the rubber seat abuts against the inner wall of the conical groove. As the rubber seat continues to move downward and deform under force, the rubber seat squeezes the glue between the conical groove and the rubber seat out through the liquid outlet nozzle. The glue discharged from the liquid outlet nozzle falls into the cleaned installation groove.

[0027] S5: After cleaning and gluing the installation groove, the lateral movement of the limit block no longer hinders the downward movement of the material removal lens. Under the action of the pressure seat and the gravity of the material removal lens, the material removal lens moves downward along the inner wall of the annular seat and is pressed into the installation groove, thereby realizing the installation of the material removal lens and the light board.

[0028] S6: Then the hydraulic cylinder is controlled to drive the pressing seat to move upward through the piston rod. After the pressing seat moves upward, it no longer abuts against the limit block. The limit block is reset under the elastic force of the first elastic element. The glue in the glue box is discharged into the conical groove through the liquid guide tube, and the glue missing in the conical groove is replenished. When the piston rod moves upward, the push seat is driven to move through the connecting rod and the connecting plate, so that the push seat pushes the preparation lens on the lowest side of the barrel. The preparation lens enters the discharge pipe through the connecting groove. The preparation lens cannot be moved downward for assembly under the support of the limit block.

[0029] S7: Repeat S2-S6 to achieve continuous installation of the lens and the light board until all the mounting slots on the light board are equipped with lenses;

[0030] S8: As the conveying unit continues to work, the conveying unit will continue to convey the light board with the lens installed forward, so that the light board is inserted into the light strip base at the end of the trough during transportation, completing the overall assembly of the light strip.

[0031] Compared with the prior art, the present invention provides an LED light strip and an automatic assembly device and a production method thereof, which have the following beneficial effects:

[0032] 1. The LED light strip and its automatic assembly equipment and production method integrate the gluing process with the lens installation process, thereby shortening the production line for assembling and installing the LED light strip and reducing the installation cost. Before the lens is pressed down for installation, the downward pressure on the lens is used to automatically complete the gluing work on the lens installation part, thereby effectively improving the efficiency of the automatic installation of the LED light strip and having good market application value.

[0033] 2. The LED light strip, its automatic assembly equipment and its production method, before gluing the light board, the movement of the limit block will drive the piston block to move in the pneumatic cavity through the connecting rod. The piston block squeezes the air in the pneumatic cavity and passes through the air outlet valve and the exhaust channel, and is finally discharged from the exhaust port. The exhausted air blows towards the installation groove on the lower light board to make impurities in the installation groove fly away, thereby ensuring that the light board is clean and dust-free before gluing, improving the adhesion of the glue, and thus ensuring the assembly effect of the light strip.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 and Fig.12 , an automatic assembly device for LED light strips, comprising a workbench 1, and further comprising:

[0050] A material trough 101, which is opened on the top of the workbench 1, and a light strip base 2 is provided at one end of the material trough 101;

[0051] A conveying part, which is provided with a plurality of groups distributed along the length direction of the trough 101, and each group of conveying parts includes two conveying components that cooperate with each other and are used to drive the light board 3 to move; and

[0052] A U-shaped frame 5, which is fixed on the workbench 1, and is provided with a pushing and unloading mechanism and a liquid discharge component arranged on the pushing and unloading mechanism;

[0053] The pushing and unloading mechanism includes a pushing component for pushing the lens 4 for loading and a pressing component for pushing the lens 4 for unloading.

[0054] An LED light strip is assembled by an automatic LED light strip assembly device, a light board 3 is plugged into a light strip base 2, a plurality of lamp beads 201 are arranged on the light strip base 2, each lamp bead 201 has an installation groove 202 for glue coating on the outside, and a lens 4 is installed in the installation groove 202.

[0055] Specifically, during operation, the lamp strip base 2 is placed at the end of the material trough 101, and the lamp board 3 is placed between the two conveying components of the same conveying part, so that the conveying part drives the lamp board 3, and the lamp board 3 moves to the bottom of the pushing and unloading mechanism. When the installation groove 202 of the lamp board 3 is placed directly below the annular seat 8, the pushing and unloading mechanism is controlled to work. By integrating the gluing process with the lens 4 installation process, it is convenient to shorten the production line of the LED lamp strip assembly and installation, reduce the installation cost, and before pressing down the lens 4 for installation, the downward pressure on the lens 4 is used to automatically complete the gluing work on the lens 4 installation part on the upper side of the lamp board 3, effectively improving the efficiency of the automatic installation of the LED lamp strip, and having good market application value.

[0056] Example 2: Reference Figure 1-12 , an automatic assembly device for LED light strips, based on Example 1, further, a pressing component includes a hydraulic cylinder 6 fixedly mounted on a U-shaped frame 5, a piston rod 601 of the hydraulic cylinder 6 is connected to a pressing seat 602, a feeding tube 7 is fixedly mounted at the bottom of the U-shaped frame 5, the pressing seat 602 is movably arranged in the feeding tube 7, an annular seat 8 is fixedly mounted at the bottom of the feeding tube 7, and a limiting component for limiting the downward movement of the lens 4 is arranged in the annular seat 8.

[0057] Furthermore, the pushing assembly includes a barrel 9 fixed on the U-shaped frame 5 for stacking lenses 4, the bottom of the barrel 9 is provided with a connecting groove 10 connected to the discharge pipe 7, the bottom of the barrel 9 is movably connected with a pushing seat 901 sliding in the connecting groove 10, and the top of the pushing seat 901 is provided with a baffle 9011.

[0058] Furthermore, the push seat 901 and the piston rod 601 of the hydraulic cylinder 6 are both connected with a connecting rod 11, a connecting plate 111 is provided between the two connecting rods 11, and the feed tube 7 and the barrel 9 are respectively provided with grooves 12 for the movement of the connecting rod 11.

[0059] Furthermore, the limiting assembly includes a plurality of movable grooves 13 uniformly arranged on the annular seat 8 in a circumferential shape, each movable groove 13 is slidably connected with a limiting block 131, a first elastic element 132 (the first elastic element 132 is arranged as a spring) is arranged between the limiting block 131 and the inner wall of the movable groove 13, and a first inclined surface which abuts against the movement of the lens 4 is arranged on the upper side of one end of the limiting block 131 away from the first elastic element 132.

[0060] Furthermore, the liquid outlet component includes a conical groove 14 provided on the annular seat 8 and used for storing glue, the bottom of the conical groove 14 is provided with liquid outlet nozzles 141 evenly distributed in a circumference, a rubber seat 142 is movably connected in the conical groove 14 and movably abuts against the inner wall of the conical groove 14, a moving rod 15 movably abuts against the limit block 131 is fixed on the top of the rubber seat 142, a second inclined surface is provided on the top of the moving rod 15, a slide groove 16 is provided on the annular seat 8, a slider 161 fixed to the moving rod 15 is slidably connected in the slide groove 16, a second elastic element 162 (the second elastic element 162 is set as a spring) is provided between the slider 161 and the inner wall of the slide groove 16, a glue box 17 is fixed on the top of the U-shaped frame 5, and a liquid guide tube 171 is connected between the glue box 17 and the conical groove 14.

[0061] Specifically, when the mounting groove 202 of the lamp board 3 is placed directly below the annular seat 8, the hydraulic cylinder 6 is controlled to work, and the piston rod 601 of the hydraulic cylinder 6 drives the pressure seat 602 to move downward. When the pressure seat 602 moves downward, the push seat 901 is driven to move through the connecting rod 11 and the connecting plate 111, so that the push seat 901 leaves the connecting groove 10 and moves to the side away from the feeding tube 7. As the pressure seat 602 continues to move upward, the baffle 9011 connected to the outside of the push seat 901 no longer resists the prepared lens 4 on the lower side of the barrel 9, and the prepared lens 4 on the lower side of the barrel 9 automatically falls under the action of its own gravity.

[0062] After the pressing seat 602 moves downward, it contacts the lower side of the feeding tube 7 and the feeding lens 4 placed on the limit block 131. The feeding lens 4 placed on the limit block 131 moves downward under the force. The feeding lens 4 presses the first inclined surface of the limit block 131. The limit block 131 avoids the downward movement of the feeding lens 4.

[0063] When the limit block 131 moves, it presses the second inclined surface at the end of the moving rod 15. The moving rod 15 is forced to drive the rubber seat 142 to move downward. When the rubber seat 142 does not abut against the inner wall of the tapered groove 14, the glue in the tapered groove 14 will not be squeezed out from the liquid outlet 141. As the moving rod 15 continues to move downward, the rubber seat 142 abuts against the inner wall of the tapered groove 14. As the rubber seat 142 continues to move downward and deform under force, the rubber seat 142 squeezes the glue between the tapered groove 14 and the rubber seat 142 out through the liquid outlet 141. The glue discharged from the liquid outlet 141 falls into the cleaned installation groove 202.

[0064] After the glue is dripped into the installation groove 202, the limit block 131 completes the lateral movement, and the limit block 131 no longer hinders the downward movement of the lower material lens 4. Under the action of the pressure seat 602 and the gravity of the lower material lens 4, the lower material lens 4 moves downward along the inner wall of the annular seat 8 and is pressed into the installation groove 202, thereby realizing the downward pressing installation of the lower material lens 4 and the light board 3;

[0065] The gluing process is integrated with the lens 4 installation process, which is convenient for shortening the production line of LED light strip assembly and installation, reducing installation costs, and before pressing down the lens 4 for installation, the downward pressure on the lens 4 is used to automatically complete the gluing work on the lens 4 installation part on the light board 3, thereby effectively improving the efficiency of the LED light strip automated installation.

[0066] Example 3: Reference Figure 7-11 , an automatic assembly device for LED light strips, based on Example 2, further, a pneumatic chamber 18 is provided in the annular seat 8, an air inlet valve and an air outlet valve are provided on the pneumatic chamber 18, a piston block 181 is slidably connected in the pneumatic chamber 18, a connecting rod 182 is provided between the piston block 181 and the limit block 131, a third elastic element 183 is provided between the piston block 181 and the inner wall of the pneumatic chamber 18 (the third elastic element 183 is set as a spring), an exhaust channel connected to the air outlet valve is provided in the annular seat 8, and a plurality of exhaust ports 184 arranged on the bottom side of the annular seat 8 are provided at one end of the exhaust channel away from the air outlet valve.

[0067] Specifically, when the pressure seat 602 presses the limit block 131 through the lens 4, the movement of the limit block 131 will drive the piston block 181 to move in the pneumatic chamber 18 through the connecting rod 182, and the piston block 181 squeezes the air in the pneumatic chamber 18 and passes through the air outlet valve and the exhaust channel, and is finally discharged from the exhaust port 184. The exhausted air blows towards the mounting groove 202 on the lower lamp board 3 to make the impurities in the mounting groove 202 fly away, thereby ensuring the cleanliness and dust-freeness of the lamp board 3 before gluing, improving the adhesion of the glue, and thus ensuring the assembly effect of the lamp strip; it should be noted that the piston block 181 first cleans the impurities in the mounting groove 202, and the rubber seat 142 squeezes the glue in the conical groove 14 to avoid the glue dripping on the impurities in the mounting groove 202 and affecting the installation effect of the lens 4.

[0068] Example 4: Reference Figure 1 and Figure 3, an automatic assembly device for LED light strips, based on Example 3, further, a conveying component includes a mounting plate 19 fixedly mounted on a workbench 1, a driving motor 191 fixedly mounted on the mounting plate 19, an output shaft of the driving motor 191 is connected to a first rotating shaft 192, a conveying wheel 193 is arranged on the first rotating shaft 192, a screw 194 is threadedly connected to the mounting plate 19, a moving block 195 slidably connected to the mounting plate 19 is rotatably connected at the bottom of the screw 194, a second rotating shaft 196 is arranged on the moving block 195, an auxiliary wheel 197 is arranged on the second rotating shaft 196, and the light board 3 slides between the conveying wheel 193 and the auxiliary wheel 197.

[0069] Specifically, according to the thickness of the lamp board 3, the screw 194 is rotated so that the screw 194 drives the moving block 195 to move in the mounting plate 19, and then the distance between the conveying wheel 193 and the auxiliary wheel 197 is adjusted, so that the lamp board 3 is placed between the conveying wheel 193 and the auxiliary wheel 197, and the driving motor 191 is controlled to operate. The output shaft of the driving motor 191 drives the first rotating shaft 192 to rotate, and the first rotating shaft 192 drives the conveying wheel 193 to rotate, and the conveying wheel 193 cooperates with the auxiliary wheel 197 to convey the lamp board 3.

[0070] The present invention also discloses a production method of an automatic assembly device for LED light strips, comprising the following steps:

[0071] S1: During operation, the light strip base 2 is placed at the end of the material trough 101, the light board 3 is placed between two conveying components of the same conveying part, and the light board 3 is placed between the auxiliary wheel 197 and the conveying wheel 193;

[0072] S2: Control the driving motor 191 to run, the output shaft of the driving motor 191 drives the first rotating shaft 192 to rotate, the first rotating shaft 192 drives the conveying wheel 193 to rotate, the conveying wheel 193 cooperates with the auxiliary wheel 197 to convey the lamp board 3, so that the lamp board 3 moves to the bottom of the pushing and unloading mechanism;

[0073] S3: When the mounting groove 202 of the lamp board 3 is placed directly below the annular seat 8, the hydraulic cylinder 6 is controlled to work, and the piston rod 601 of the hydraulic cylinder 6 drives the pressure seat 602 to move downward. When the pressure seat 602 moves downward, the push seat 901 is driven to move through the connecting rod 11 and the connecting plate 111, so that the push seat 901 leaves the connecting groove 10 and moves to the side away from the feeding tube 7. As the pressure seat 602 continues to move upward, the baffle 9011 connected to the outside of the push seat 901 no longer resists the prepared lens 4 on the lower side of the barrel 9, and the prepared lens 4 on the lower side of the barrel 9 automatically falls under the action of its own gravity;

[0074] After the pressing seat 602 moves downward, it contacts the lower side of the feeding tube 7 and the feeding lens 4 placed on the limit block 131. The feeding lens 4 placed on the limit block 131 moves downward under the force. The feeding lens 4 presses the first inclined surface of the limit block 131. The limit block 131 avoids the downward movement of the feeding lens 4.

[0075] S4: When the pressure seat 602 presses the limit block 131 through the lens 4, the movement of the limit block 131 drives the piston block 181 to move in the pneumatic chamber 18 through the connecting rod 182, and the piston block 181 squeezes the air in the pneumatic chamber 18 and passes through the air outlet valve and the exhaust channel, and finally is discharged from the exhaust port 184. The discharged air blows toward the installation groove 202 on the lower lamp board 3, so that the impurities in the installation groove 202 fly away;

[0076] When the limit block 131 moves, it presses the second inclined surface at the end of the moving rod 15. The moving rod 15 is forced to drive the rubber seat 142 to move downward. When the rubber seat 142 does not abut against the inner wall of the tapered groove 14, the glue in the tapered groove 14 will not be squeezed out from the liquid outlet 141. As the moving rod 15 continues to move downward, the rubber seat 142 abuts against the inner wall of the tapered groove 14. As the rubber seat 142 continues to move downward and deform under force, the rubber seat 142 squeezes the glue between the tapered groove 14 and the rubber seat 142 out through the liquid outlet 141. The glue discharged from the liquid outlet 141 falls into the cleaned installation groove 202.

[0077] S5: After cleaning and gluing the inside of the installation groove 202, the lateral movement of the limit block 131 no longer hinders the downward movement of the material-cutting lens 4. Under the action of the pressure seat 602 and the gravity of the material-cutting lens 4, the material-cutting lens 4 moves downward along the inner wall of the annular seat 8 and is pressed into the installation groove 202, thereby realizing the installation of the material-cutting lens 4 and the light board 3.

[0078] S6: Then the hydraulic cylinder 6 is controlled to drive the pressure seat 602 to move upward through the piston rod 601. After the pressure seat 602 moves upward, it no longer contacts the limit block 131. The limit block 131 is reset under the elastic force of the first elastic element 132. The glue in the glue box 17 is discharged into the conical groove 14 through the liquid guide tube 171, and the glue missing in the conical groove 14 is replenished. When the piston rod 601 moves upward, it drives the push seat 901 to move through the connecting rod 11 and the connecting plate 111, so that the push seat 901 pushes the preparation lens 4 on the lowest side of the barrel 9.

10. A method for producing the automatic assembly equipment for LED light strips according to claim 9, characterized in that: The following steps are involved: S1: When working, the light strip base (2) is placed at the end of the material trough (101), the light board (3) is placed between two conveying components of the same conveying part, and the light board (3) is placed between the auxiliary wheel (197) and the conveying wheel (193); S2: Control the driving motor (191) to operate, the output shaft of the driving motor (191) drives the first rotating shaft (192) to rotate, the first rotating shaft (192) drives the conveying wheel (193) to rotate, the conveying wheel (193) cooperates with the auxiliary wheel (197) to convey the lamp board (3), so that the lamp board (3) moves to the bottom of the pushing and unloading mechanism; S3: When the mounting groove (202) of the lamp panel (3) is placed directly below the annular seat (8), the hydraulic cylinder (6) is controlled to work, and the piston rod (601) of the hydraulic cylinder (6) drives the pressure seat (602) to move downward. When the pressure seat (602) moves downward, the push seat (901) is driven to move through the connecting rod (11) and the connecting plate (111), so that the push seat (901) leaves the connecting groove (10) and moves to the side away from the discharge pipe (7). As the pressure seat (602) continues to move upward, the baffle (9011) connected to the outside of the push seat (901) no longer resists the preparation lens (4) on the lower side of the barrel (9), and the preparation lens (4) on the lower side of the barrel (9) automatically falls under the action of its own gravity; After the pressure seat (602) moves downward, it contacts the lower side of the material discharge tube (7) and the material discharge lens (4) placed on the limit block (131), and the material discharge lens (4) placed on the limit block (131) moves downward under force, and the material discharge lens (4) presses the first inclined surface of the limit block (131), and the limit block (131) avoids the downward movement of the material discharge lens (4); S4: When the pressure seat (602) presses the limit block (131) through the lens (4), the movement of the limit block (131) drives the piston block (181) to move in the pneumatic chamber (18) through the connecting rod (182), and the piston block (181) squeezes the air in the pneumatic chamber (18) and passes through the air outlet valve and the exhaust channel, and finally is discharged from the exhaust port (184). The discharged air blows against the installation groove (202) on the lower lamp board (3), so that impurities in the installation groove (202) fly away; When the limit block (131) moves, it presses against the second inclined surface at the end of the moving rod (15), and the moving rod (15) is forced to drive the rubber seat (142) to move downward. When the rubber seat (142) does not abut against the inner wall of the conical groove (14), the glue in the conical groove (14) will not be squeezed out from the liquid outlet nozzle (141). As the moving rod (15) continues to move downward, the rubber seat (142) abuts against the inner wall of the conical groove (14). As the rubber seat (142) continues to move downward and deform under force, the rubber seat (142) squeezes the glue between the conical groove (14) and the rubber seat (142) out through the liquid outlet nozzle (141), and the glue discharged from the liquid outlet nozzle (141) falls into the installation groove (202) after cleaning. S5: After cleaning and gluing the inside of the installation groove (202), the lateral movement of the limit block (131) no longer hinders the downward movement of the material removal lens (4). Under the action of the pressure seat (602) and the gravity of the material removal lens (4), the material removal lens (4) moves downward along the inner wall of the annular seat (8) and is pressed into the installation groove (202), thereby achieving the installation of the material removal lens (4) and the light board (3); S6: Then, the hydraulic cylinder (6) is controlled to drive the pressure seat (602) to move upward through the piston rod (601). After the pressure seat (602) moves upward, it no longer contacts the limit block (131). The limit block (131) is reset under the elastic force of the first elastic element (132). The glue in the glue box (17) is discharged into the conical groove (14) through the liquid guide tube (171), and the missing glue in the conical groove (14) is replenished. When the piston rod (601) moves upward, it drives the push seat (901) to move through the connecting rod (11) and the connecting plate (111), so that the push seat (901) pushes the preparation lens (4) at the lowest side of the barrel (9). The preparation lens (4) enters the discharge pipe (7) through the connecting groove (10). The preparation lens (4) cannot be moved downward for assembly under the support of the limit block (131); S7: Repeat S2-S6 to achieve continuous installation of the lens (4) and the light board (3) until all the lenses (4) are installed in the installation grooves (202) on the light board (3); S8: As the conveying unit continues to work, the conveying unit will continue to convey the light board (3) with the lens (4) installed forward, so that the light board (3) is inserted into the light strip base (2) at the end of the material trough (101) during transportation, completing the overall assembly of the light strip.
