Description

Technical Field

[0001] This invention belongs to the field of LED strip light application technology, and in particular relates to an automatic LED strip light application machine. Background Technology

[0002] LED chips are typically encapsulated within a strip-shaped LED light strip, with a large number of chips arranged in a strip. The earliest LED light strips had chips soldered onto copper wires, encased in a plastic tube. Later, LED light strips were improved to use a flexible circuit board structure, employing FPC (Flexible Printed Circuit) as the carrier for the LED chips. This is a highly reliable and extremely flexible printed circuit board made with polyimide or polyester film as the substrate, used to arrange multiple LED chips. This type of LED light strip has a simple manufacturing process, long lifespan, rich colors, and easy quality control. Furthermore, this method allows for the full release of the LED light strip's light source, and the manufactured LED light strip needs to be attached to the light frame.

[0003] The current production process for this product involves manual application of the LED strip. Due to inconsistent worker techniques, the pressing position is difficult to control, and the application pressure is uneven. This can result in loose adhesion or excessive pressure, potentially damaging the chip inside the LED strip and posing a quality risk. Furthermore, the manual application process requires peeling off the adhesive backing paper while simultaneously applying the LED strip, making continuous operation impossible and impacting production efficiency.

The short vertical plate of the third L-shaped plate is connected to the vertical block of the L-shaped seat, and the horizontal long plate end of the third L-shaped plate is fitted with a roller.

[0009] In a preferred embodiment, the spring buffer mechanism further includes a second spring, a locking screw, and an adjusting nut; the two ends of the second spring are respectively connected to the vertical block of the L-shaped seat and the side of the vertical block of the T-shaped block by two locking screws; the guide sleeve is fixed in the through hole opened on the vertical block of the T-shaped block by a vertical locking screw; the end of the guide rod near the T-shaped block moves through the guide sleeve, and the rod through which the guide rod moves is a threaded rod; an adjusting nut is connected to the threaded rod, and the adjusting nut is located at the outer end of the guide sleeve.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0021] Please see Figures 1-10 As shown, the present invention is an automatic LED strip attaching machine, including a housing 1 and an air circuit unit installed inside the housing 1; it also includes: The pallet fixture 2 is detachably mounted on four columns 23 by screws, so that the pallet fixture 2 is suspended above the chassis 1, and the inner ring surface of the pallet fixture 2 is provided with a support ring groove 21 for placing the material frame 3. The tray fixture 2 has a front end slot 22 that communicates with the support ring groove 21. The front end slot 22 cooperates with the front end protrusion 31 of the material frame 3 to fix the LED light strip head. The rotating mechanism 4 is installed inside the housing 1, and its output shaft extends outside the housing 1. The rotating mechanism 4 is preferably a motor. The cylinder mechanism 5 is horizontally mounted on the pallet fixture 2 and is connected to the output shaft of the rotating mechanism 4 through the bracket mechanism 6. The cylinder mechanism 5 is preferably a double-rod cylinder. The spring buffer mechanism 7 is connected to the output end of the horizontally mounted cylinder mechanism 5; Roller 8 is installed at the end of spring buffer mechanism 7 near support ring groove 21 and is used to press and adhere the LED light strip with the backing paper torn off to the material frame 3. And the adhesive paper recycling mechanism 9, which is mounted on the spring buffer mechanism 7 and is located on one side of the circumferential rotation direction of the roller 8, for the purpose of rolling up and recycling the torn adhesive paper. Furthermore, the shape of the material frame 3 detachably mounted on the support ring groove 21 is preferably either plum blossom-shaped or circular; Furthermore, an annular disk 81 is formed on the top outer ring surface of the roller 8, and the diameter of the annular disk 81 is larger than the diameter of the roller 8. An annular groove 82 is provided in the middle of the roller 8, and the vertical width of the groove 82 is adapted to the vertical width of the LED light strip core. As a preferred embodiment of the present invention, the specific operation method of attaching the LED light strip to the material frame 3 using the automatic tape attaching machine of this solution is as follows: Taking the plum blossom-shaped material frame 3 as an example First: Select the size of the tray fixture 2 according to the size of the material frame 3 to be bonded, and then adjust the height of the support mechanism 6 accordingly so that the height of the roller 8 matches the height of the installed tray fixture 2, as well as the radial movement distance of the roller 8, so that when the cylinder mechanism 5 pushes the roller 8 to move radially through the spring buffer mechanism 7, the roller 8 can accurately match the material frame 3 installed on the tray fixture 2. Second, place the plum blossom-shaped material frame 3 of the LED light strip to be attached into the support ring groove 21, and make the material frame 3 contact the bottom of the support ring groove 21, while the front protrusion 31 of the material frame 3 is simultaneously inserted into the front slot 22, so as to install the material frame 3 onto the tray fixture 2. Then, fix the LED strip head to be bonded to the groove opened in the front protrusion 31 of the material frame 3, and then peel off the backing paper of the LED strip near the head of the strip, and the peeled backing paper is attached to the backing paper recycling mechanism 9. If the roller 8 is located at the head of the LED strip to be bonded, the green start button on the side of the industrial control screen on the front of the chassis 1 can be pressed to extend the output rod of the double-rod cylinder. This will cause the spring buffer mechanism 7 to move radially first. At this time, the roller 8 will move synchronously towards the front protrusion 31 of the material frame 3. When the roller 8 contacts the LED strip initially bonded on the material frame 3, the rotary motor of the rotating mechanism 4 will work, causing it to drive the cylinder mechanism 5 to rotate clockwise through the bracket mechanism 6. Then, the spring buffer mechanism 7 will synchronously drive the roller 8 to rotate clockwise, so as to press the LED strip tightly bonded to the material frame 3. Since the roller 8 is provided with an annular disk 81, the rotating roller 8 can vertically limit and press the bonded LED strip through the annular disk 81. When the LED strip is continuously pressed and bonded to the material frame 3 in the revolution state of the roller 8, the adhesive paper recycling mechanism 9 will synchronously roll up the torn adhesive paper. It should be noted that the tray fixture 2 is detachably mounted on the column 23 by screws. Different sizes of tray fixture 2 can be replaced according to the size of the material frame 3 to be attached to the LED light strip. Through the cooperation of the front slot 22 and the front protrusion 31 of the material frame 3, the material frame 3 installed on the support ring groove 21 can be circumferentially limited to prevent the material frame 3 from rotating due to the pressure of the roller 8 when the roller 8 rotates in a circle. The automatic LED strip attaching machine of the present invention has the following beneficial effects: Firstly, the tray fixture 2 suspended above the chassis 1 can be used to install material frames 3 of different shapes. Through the cooperation of the rotating mechanism 4 and the cylinder mechanism 5, the roller 8 can move radially and rotate circumferentially. The spring buffer mechanism 7 can also buffer and guide the circumferentially rotating roller 8, thereby enabling the automatic tape applicator of the present invention to press and adhere the LED light strip tightly to the material frame 3, effectively solving the pain point problem of manual pressing. Secondly, when the roller 8 rotates to the trough of the plum blossom-shaped material frame 3, under the action of the spring buffer mechanism 7, the roller 8 can accurately and tightly press the LED light strip onto the trough of the plum blossom-shaped material frame 3. When the roller 8 rotates to the crest of the plum blossom-shaped material frame 3, the spring buffer mechanism 7 can move the roller 8 towards the center line of the tray fixture 2, so that the spring buffer mechanism 7 can play the role of radial displacement compensation and tension buffer for the roller 8. Thus, when the roller 8 rotates in a circle, it can quickly and accurately press the LED light strip onto the material frame 3 of different shapes. Thirdly, because the top outer ring surface of the roller 8 forms an annular disk 81, the rotating roller 8 can vertically limit and press the attached LED light strip through the annular disk 81, preventing the LED light strip from extending beyond the top of the material frame 3, thus affecting the quality and precision of the LED light strip bonding. The roller 8 has an annular groove 82 in the middle of its body, making the cross-section of the roller 8 U-shaped. When the roller 8 rotates and presses the LED light strip, the roller 8 will only press the blank area of ​​the LED light strip, not the LED light strip core. This allows the rotating roller 8 to press the LED light strip tightly onto the material frame 3 without damaging the LED light strip core.

[0022] See Figure 3 and Figure 4As shown, the support mechanism 6 includes a base plate 61, a first L-shaped plate 62, a second L-shaped plate 63, and a horizontal support plate 64. The base plate 61 is fixedly mounted on the top end of the output shaft. The horizontal plate of the first L-shaped plate 62 is fixedly connected to the base plate 61 by screws. The vertical plate of the inverted second L-shaped plate 63 is also connected to the vertical plate of the first L-shaped plate 62 by screws. The horizontal support plate 64 is also connected to the horizontal plate of the second L-shaped plate 63 by screws, and a cylinder mechanism 5 is fixedly mounted on the horizontal support plate 64. Furthermore, the horizontal plate of the first L-shaped plate 62 has a countersunk groove 65 for screw connection along its length direction, the vertical plate of the second L-shaped plate 63 also has a countersunk groove 65 for screw connection along its height direction, and the upper surface of the horizontal support plate 64 also has a countersunk groove 65 for screw connection along its length direction. As a preferred embodiment of the present invention, since the horizontal plate of the first L-shaped plate 62 is connected to the base plate 61 by screws, and the hexagonal screws are located in the countersunk waist-shaped groove 65, it is convenient to adjust the installation position of the horizontal plate of the first L-shaped plate 62 on the base plate 61, thereby facilitating the increase of the radial movement space of the roller 8. The vertical plates of the first L-shaped plate 62 and the second L-shaped plate 63 are also connected by screws. The waist-shaped groove 65 opened on the vertical plate of the second L-shaped plate 63 can adjust the connection position between the two vertical plates, thereby facilitating the adjustment of the height between the horizontal plates of the first L-shaped plate 62 and the second L-shaped plate 63, and thus facilitating the adjustment of the vertical height of the roller 8. The horizontal support plate 64 connected to the upper surface of the second L-shaped plate 63 not only facilitates the installation of the cylinder mechanism 5, but also facilitates the installation of the spring buffer mechanism 7, enabling it to accurately push the roller 8 to move radially.

[0023] See Figure 5 and Figure 6 As shown, the spring buffer mechanism 7 includes a T-shaped block 71, a guide sleeve 72, a guide rod 73, a first spring 74, a guide rail 75, an L-shaped seat 76, and a third L-shaped plate 77. The T-shaped block 71 is mounted on the stop block of the cylinder mechanism 5 by screws. The vertical block of the T-shaped block 71 is equipped with a guide sleeve 72, and a guide rod 73 is movably installed inside the guide sleeve 72. A first spring 74 is sleeved on the guide rod 73. The two ends of the first spring 74 are connected to the connecting blocks fixed at the ends of the guide sleeve 72 and the guide rod 73. The guide rail 75 is fixedly installed on the upper surface of the horizontal support plate 64 away from the cylinder mechanism 5. An L-shaped seat 76 is installed on the slider of the guide rail 75. The vertical block of the L-shaped seat 76 is fixedly connected to the connecting block of the guide rod 73. The short vertical plate of the third L-shaped plate 77 is connected to the vertical block of the L-shaped seat 76, and a roller 8 is installed at the end of the horizontal long plate of the third L-shaped plate 77. In a preferred embodiment of the present invention, since the first spring member 74, which is sleeved on the guide rod 73 and whose two ends are connected to the L-shaped seat 76 and the end of the guide sleeve 72, is in its initial state, when the output rod of the cylinder mechanism 5 extends, the T-shaped block 71 will first drive the L-shaped seat 76 to move towards the material frame 3 through the guide sleeve 72 and the guide rod 73. The guide rail 75 installed on the horizontal support plate 64 can play a guiding and supporting role for the radially moving L-shaped seat 76. When the L-shaped seat 76 moves horizontally, the horizontal long plate of the third L-shaped plate 77 will drive the roller 8 located on the lower surface of the end to move towards the side of the material frame 3, so that the wheel body of the roller 8 can contact the strip body of the LED light strip that is initially attached. When the roller 8 rotates in a circle and presses the LED light strip tightly against the plum blossom-shaped material frame 3, the roller 8 will move continuously at the troughs and crests of the material frame 3. When the roller 8 moves from the trough to the crest of the material frame 3, the roller 8 will be pushed by the section of the material frame 3 from the trough to the crest. Since the guide rod 73 is slidably inserted into the guide sleeve 72, the roller 8, which is pushed, will move towards the center line of the tray fixture 2. The L-shaped seat 76 will slide on the guide rail 75. At this time, the first spring 74 will be compressed. The elastic thrust of the compressed first spring 74 will act on the roller 8 through the L-shaped seat 76 and the third L-shaped plate 77, so that it does not interfere with the normal radial displacement of the roller 8 while pressing the LED light strip tightly against the plum blossom-shaped material frame 3. When the roller 8 rotates to press the LED light strip tightly against the circular material frame 3, since the guide rod 73 is inserted into the guide sleeve 72, the rotating mechanism 4 will drive the guide rail 75, L-shaped seat 76 and third L-shaped plate 77 to rotate through the bracket mechanism 6, which will facilitate the roller 8 to rotate to press the LED light strip tightly against the circular material frame 3. The spring buffer mechanism 7 of this solution works by the cooperation of the guide sleeve 72 fixed on the T-block 71, the guide rod 73 slidably inserted into the guide sleeve 72, the first spring 74, the L-shaped seat 76 and the third L-shaped plate 77. When the cylinder mechanism 5 is working, the first spring 74 will cause the guide sleeve 72 and the guide rod 73 to act as a "radial push rod", which will push the L-shaped seat 76 and the third L-shaped plate 77 to drive the roller 8 to move towards the material frame 3, so that the roller 8 can accurately fit and contact the material frame 3 and the LED light strip. When the roller 8 rotates between the troughs and crests of the plum blossom-shaped material frame 3, since the material frame 3 is fixed in the support ring groove 21, the roller 8 will be pushed by the material frame 3, causing the guide rod 73 to slide in the guide sleeve 72, and the first spring 74 will be compressed. At this time, the cooperation of the guide sleeve 72, the guide rod 73, the first spring 74, the L-shaped seat 76 and the T-shaped block 71 can play the role of radial displacement compensation and tension buffer for the radially moving roller 8, so that the roller 8 can slide radially when rotating in a circle, thereby enabling the automatic tape applicator of the present invention to accurately and quickly apply LED light strips to material frames 3 of different shapes.

[0024] See Figure 5 and Figure 6 As shown, the spring buffer mechanism 7 also includes a second spring 78, a locking screw 79, and an adjusting nut 791; The two ends of the second spring member 78 are respectively connected to the vertical block of the L-shaped seat 76 and the side of the vertical block of the T-shaped block 71 by two locking screws 79. The guide sleeve 72 is fixed in the through hole opened on the vertical block of the T-shaped block 71 by the vertical locking screw 79. The end of the guide rod 73 near the T-shaped block 71 moves through the guide sleeve 72, and the rod through which the guide rod 73 moves is a threaded rod. An adjusting nut 791 is connected to the threaded rod, and the adjusting nut 791 is located at the outer end of the guide sleeve 72. As a preferred embodiment of the present invention, the second spring member 78, which is detachably installed on the front side of the L-shaped seat 76 and the T-shaped block 71 by means of the locking screw 79, can further improve the buffering effect of the spring buffer mechanism 7 on the circumferentially rotating roller 8 and prevent the output shaft thrust of the cylinder mechanism 5 from being too large, which would cause the material frame 3 to be squeezed and deformed. The guide sleeve 72 can be detachably installed on the T-block 71 by locking screw 79. This not only allows for adjustment of the length of the guide sleeve 72 extending from the side of the L-shaped seat 76, but also allows for the disassembly and replacement of the guide sleeve 72 that has been used for a long time. The guide rod 73 near the T-block 71 is a threaded rod, and the threaded rod extending out of the guide sleeve 72 is fixedly installed by the adjusting nut 791. Therefore, when the roller 8 is pressed and moves towards the center line of the tray fixture 2, the guide rod 73 will slide inside the guide sleeve 72, and the adjusting nut 791 will move away from the end of the guide sleeve 72, so that the adjusting nut 791 threaded to the end of the threaded rod will not interfere with the normal sliding of the guide rod 73 inside the guide sleeve 72. When the roller 8 moves towards the material frame 3 under the elastic thrust of the first spring 74, the adjusting nut 791 can also play a radial limiting role on the sliding guide rod 73, preventing the roller 8 from moving excessively under the elastic thrust of the first spring 74, which would cause the material frame 3 to deform or be damaged. Meanwhile, the threaded adjusting nut 791 can adjust the length of the guide rod 73 extending out of the guide sleeve 72, thereby changing the elastic deformation capability of the first spring member 74, so that the roller 8 can press and adhere the LED light strip to the material frame 3 of the size, and will not cause the material frame 3 to be damaged or deformed due to the large elastic deformation force required by the first spring member 74 being subjected to large pressure from the roller 8.

[0025] See Figure 7 As shown, the adhesive paper recycling mechanism 9 includes a T-shaped bracket 91, a support shaft 92, a first pulley 93, a second pulley 94, a timing belt 95, a support disc 96, and a take-up drum 97; Among them, a T-shaped bracket 91 is installed on one side of the horizontal long plate of the third L-shaped plate 77, and a support shaft 92 is rotatably installed on the T-shaped bracket 91 through a bearing; and the bottom end of the support shaft 92 extends out of the T-shaped bracket 91 and is fixedly sleeved with a first pulley 93. The roller 8 is rotatably mounted on the lower surface of the horizontal long plate end of the third L-shaped plate 77 via a rotating shaft, and a second pulley 94 is fixedly sleeved on the rotating shaft above the roller 8. The second pulley 94 and the first pulley 93 are connected by a synchronous belt 95. A support disk 96 is fixedly mounted on the support shaft 92 located above the T-shaped bracket 91, and the take-up drum 97 is sleeved on the support shaft 92 located above the support disk 96. The inner wall of the lower opening of the take-up drum 97 is provided with a slot 98, preferably two, four or six slots 98. A protrusion 99 is provided on the outer ring surface of the support shaft 92 near the support disk 96, and the protrusion 99 and the slot 98 cooperate with each other. As a preferred embodiment of this solution, in order to facilitate the simultaneous winding and recycling of the torn adhesive paper, the present invention is designed as follows: When the tape applicator is needed, the take-up drum 97 should first be fitted onto the outside of the support shaft 92, and the slot 98 at the bottom of the take-up drum 97 should be aligned with the protrusion 99. Then, the take-up drum 97 should be pushed down so that the protrusion 99 of the elastic rubber material can be squeezed into the slot 98, thereby installing the take-up drum 97 on the support shaft 92. After the adhesive paper on the LED strip to be bonded is peeled off, it needs to be adhered to the take-up drum 97. When the rotating mechanism 4 operates, causing the roller 8 to rotate around the tray fixture 2, the roller 8 not only presses the LED strip tightly against the material frame 3, but also, because the roller 8 is rotatably mounted on the horizontal long plate of the third L-shaped plate 77 through the cooperation of a rotating shaft and bearing, the friction between the roller 8 and the LED strip and the material frame 3 will cause it to generate... The roller 8 rotates on its own, and the rotation of the roller 8 is coordinated with the first pulley 93, the timing belt 95 and the second pulley 94 to make the support shaft 92 rotate on the T-shaped bracket 91. The rotation of the support shaft 92 is then coordinated with the slot 98 and the protrusion 99 to drive the take-up drum 97 to rotate, so that the rotating take-up drum 97 can take up the continuously torn adhesive paper. When the amount of adhesive paper rolled up on the take-up drum 97 reaches a certain amount, the take-up drum 97 can be directly removed and replaced. This invention installs an adhesive paper recycling mechanism 9 on one side of the horizontal long plate of the third L-shaped plate 77 in the direction of rotation. The T-shaped bracket 91 can rotate and support the supporting shaft 92 and the take-up drum 97. The take-up drum 97 is a distance away from the roller 8. Therefore, when the third L-shaped plate 77 drives the roller 8 to rotate, the synchronous rotation of the take-up drum 97 can tear the adhesive paper from the LED light strip. When the rotation of the roller 8 presses the LED light strip with the torn adhesive paper onto the material frame 3, it can also press the LED light strip tightly, which can prevent the LED light strip from shifting when the adhesive paper is torn from the LED light strip. As the roller 8 rotates in a circle, the friction between the roller 8 and the LED light strip will also cause it to rotate. In turn, the rotating shaft, through the cooperation of the first pulley 93, the second pulley 94 and the synchronous belt 95, can drive the take-up drum 97 sleeved on the supporting rotating shaft 92 to rotate. This makes it easier to recycle the continuously torn adhesive paper. This solution eliminates the need for a separate power source for the take-up drum 97, allowing the LED light strip to be pressed and bonded while the torn adhesive paper is quickly recycled.
