Description

Technical Field

[0001] This invention relates to the field of LED strip assembly technology, and in particular to an automated assembly line and its assembly process. Background Technology

[0002] Some LED light strips use a chain-type design, where the chain consists of multiple chain components that are interlocked end-to-end. Each chain component has a lens installed, and the chain can be bent in all directions when connected to the flexible light panel. Currently, the assembly of this type of chain-type LED light strip between the chain and the light panel mainly relies on manual assembly. The process is as follows: First, the chain components are interlocked one by one to form a chain. Next, the lenses need to be manually inserted into the chain components. Then, the light panel is soldered and bent on the light strip using a soldering and bending mechanism. After that, the soldered and bent light panel is assembled onto the chain and the back plate is fastened. Finally, it is rolled up through a mold. Basically, each process requires a separate worker, resulting in many processes, a large number of personnel, and low production efficiency. Summary of the Invention

The pins pass through the forming slope of the lamp plate. The third material channel is located between the fifth cylinder and the sixth cylinder and communicates with the fifth cylinder. The fifth cylinder is located on the side of the pin guide rail. The seventh cylinder is located on the other side of the pin guide rail. The sixth cylinder pushes out to push the backplate under the suction fixture so that the suction fixture holds the backplate, so that the fifth cylinder pushes the backplate to the installation position so that the backplate and the lamp plate form an installation angle. One end of the backplate is already locked into a locking position on one side of the chain. The seventh cylinder pushes out to lock the other end of the backplate into a locking position on the other side of the chain, thereby completing the backplate installation.

[0014] According to some embodiments of the present invention, the first dragging mechanism and the second dragging mechanism have the same structure. The first dragging mechanism includes a finger cylinder and a second rodless cylinder capable of reciprocating along the feed channel. The finger cylinder is disposed on the feed channel to clamp / release the chain, and the second rodless cylinder is disposed above the finger cylinder to drive the finger cylinder to reciprocate.

[0016] It may also include a first through-molding fixture and a second through-molding fixture, wherein the first through-molding fixture is disposed on the soldering device to perform through-molding detection on the lamp board, and the second through-molding fixture is disposed between the back plate fastening structure and the second dragging mechanism to perform through-molding detection on the lamp strip;

[0017] It may also include a detection lens, which is located between the backplate fastening mechanism and the second through-molding fixture, to inspect the light strip.

[0018] An assembly process according to a second embodiment of the present invention, applied to the above-mentioned automated assembly line, includes the following steps:

[0019] Step 1: Prepare a pre-fastened spare chain, insert the spare chain into the feed channel and run it through the entire feed channel, then wind it up to the rear reel for traction;

[0020] Step 2: The chain components are vibrated by the first vibrating plate and enter the guide rail along the first material channel. The macro lens identifies whether the direction of the chain components on the guide rail is consistent.

[0021] Step 3: If the direction is consistent, continue to flow into the lower part of the small cylinder 3; if the direction is inconsistent, after being rotated 180° by the rotary cylinder, continue to flow into the lower part of the second cylinder (while the rotary cylinder is rotating, the support cylinder pushes out to press the rotated chain accessory, and at the same time the first cylinder pushes out to avoid interference and collision between the incoming chain accessory and the rotating chain accessory).

[0022] Step 4: The first rodless cylinder moves to one end, and the slide cylinder at one end slides upward to make the load block align with the guide rail on one side. The second cylinder retracts to make the chain accessory fall into the load block, and then the slide cylinder slides downward to the initial position.

[0023] Step 5: The first rodless cylinder slides to the middle position at the other end, so that the load block on the slide cylinder at one end abuts against the material channel. At the same time, the slide cylinder at the other end slides upward so that the load block aligns with the guide rail on the other side to complete the material picking action of the chain accessory. The slide cylinder that has slid to the middle rotates around the rotating structure so that the chain accessory on its load block is aligned with the assembly position of the chain accessory on the material channel. The third cylinder pushes downward to fasten the two aligned chain accessories.

[0024] Step 6: The first dragging mechanism drags the chain to the lens mounting mechanism, and at the same time the lens enters the positioning track through the lens feeding device. The cylinder assembly pushes out to fasten the lens to the fastening position on the chain.

[0025] Step 7: The first dragging mechanism drags the chain to the lamp board channel; at the same time, the lamp boards on the first reel are dragged by the second dragging mechanism and sequentially enter the soldering channel for soldering, enter the pressing channel for pressing to form a shaped slope on the lamp board, and enter the lamp board channel. The lamp board fastening mechanism fastens the lamp board and the chain.

[0026] Step 8: The chain with the light panel attached enters the light strip channel under the drag of the second drag mechanism to attach the back panel and form a light strip. The light strip passes through the second drag mechanism to be wound into the second reel.

[0027] The automated assembly line and assembly process according to embodiments of the present invention have at least the following beneficial effects: the chain fastening mechanism, lens mounting mechanism, first dragging mechanism, soldering device, slope pressing device, lamp board fastening mechanism, back plate fastening mechanism, and second dragging mechanism are sequentially distributed along the material channel. After the chain components are formed into a chain by the chain fastening mechanism, they are automatically moved to the lens mounting mechanism along the material channel under the drag of the first dragging mechanism. Since the positioning track is located below the material channel, the lens on the positioning track can be automatically mounted onto the chain by the action of the cylinder assembly. No manual installation is required. Next, the chain with the lens installed moves automatically along the feed channel to the lamp panel fastening mechanism under the drag of the first drag mechanism. Simultaneously, the lamp panel, dragged by the second drag mechanism, sequentially passes through the soldering channel for soldering, then through the beveling channel for beveling, and then enters the lamp panel channel to fasten with the chain. Next, it enters the backplate fastening mechanism along the feed channel to complete the backplate fastening, forming the light strip. After inspection by the second die-cutting fixture, the second drag mechanism connects to the light strip to simultaneously drag the lamp panel, chain, and light strip along the feed channel. Finally, the light strip is wound onto the second reel. Throughout the entire light strip assembly process, the chain and lamp panel are dragged by the first and second drag mechanisms, moving automatically along the feed channel to complete the corresponding processes step by step until the light strip is assembled, saving manpower and improving production efficiency.

[0041] Reference Figures 1 to 8The present invention discloses an automated assembly line, comprising a frame, a feed channel 100 for conveying a chain, and chain fastening mechanisms 10 for fastening chain accessories, a lens mounting mechanism 20 for mounting lenses onto the chain, a first dragging mechanism 30, a soldering device 40 for soldering a lamp board 300, a slope pressing device 50 for slope pressing the lamp board 300, a lamp board fastening mechanism 60 for fastening the lamp board 300 and the chain, and a back plate fastening mechanism 70 for fastening a back plate onto the lamp board 300. The second drag mechanism 80 also includes a chain feeding device for conveying chain accessories, a lens feeding device for conveying lenses, and a back plate feeding device for conveying back plates. The chain feeding device is connected to the inlet of the chain fastening mechanism 10, the lens feeding device is connected to the positioning track 21, and the back plate feeding device is connected to the inlet of the back plate fastening mechanism 70. The second drag mechanism 80 also includes a first reel 91 and a second reel 92 located at the end of the feed channel 100. The first reel 91 is used to wind up the lamp panel 300, and the second reel 92 is used to wind up the lamp strip or chain.

[0042] like Figure 3 As shown, the chain feeding device includes a first vibratory plate 101 and a first material channel communicating with the first vibratory plate 101. The chain fastening mechanism 10 includes an inclined guide rail 110 communicating with the first material channel, a first rodless cylinder 111, and a slide cylinder 112 disposed on the first rodless cylinder 111. The guide rail 110 is provided with, from top to bottom, a macro lens 113 for detecting whether the direction of the chain components is consistent, a first cylinder 11, a rotary cylinder 114, a support cylinder 115 disposed above the rotary cylinder 114, and a second cylinder 12. When the directions of the chain components are inconsistent, the rotary cylinder 114 rotates the inconsistent chain components 180 degrees, and the support cylinder 115 pushes out to abut against the inconsistent chain components. At the same time, the first cylinder 11 pushes out to fix the adjacent chain components. To prevent interference between chain components, a third cylinder 13 is installed on the frame above the feed channel 100. A carrier block 119 for supporting chain components is installed on the slide cylinder 112. A first rodless cylinder 111 reciprocates along the vertical direction of the guide rail 110 to drive the carrier block 119 to dock with the guide rail 110 and the feed channel 100 respectively. When the second cylinder 12 is released, the chain components on the guide rail 110 move down to the carrier block 119. A rotating structure is provided between the slide cylinder 112 and the first rodless cylinder 111 to align the chain components on the carrier block 119 with the chain components on the feed channel 100. The third cylinder 13 pushes out to fasten the chain components on the carrier block 119 and the chain components on the feed channel 100. This cycle is repeated to complete the fastening of the chain components and form a chain.

[0043] Furthermore, there are two first material channels, and correspondingly, there are two guide rails 110. Each guide rail 110 is equipped with a corresponding macro lens 113, a first cylinder 11, a rotary cylinder 114, and a second cylinder 12. There are two corresponding sliding cylinders 112. Each sliding cylinder 112 is equipped with a carrying block 119 for carrying chain accessories. The first rodless cylinder 111 moves back and forth along the vertical direction of the guide rail 110 to drive each carrying block 119 to dock with the corresponding guide rail 110 and material channel 100 respectively. Each sliding cylinder 112 and the first rodless cylinder 111 are provided with a rotating structure so that the chain accessories on the corresponding carrying block 119 are aligned with the assembly position of the chain accessories on the material channel 100. When one sliding cylinder 112 docks with the corresponding guide rail 110, the chain accessories on the other sliding cylinder 112 are simultaneously aligned with the assembly position of the chain accessories on the material channel 100 to complete the fastening, thereby improving the chain fastening efficiency.

[0044] Furthermore, the rotating structure includes a rotating plate 116, a slider 117 disposed below the rotating plate 116, a rotating shaft 118 disposed on the rotating plate 116, and a fourth cylinder 14 connected to the slider 117. A sliding cylinder 112 is provided on the top of the rotating plate 116, and the slider 117 is disposed on the first rodless cylinder 111. When the fourth cylinder 14 is pushed out, the slider 117 moves, causing the rotating plate 116 to rotate around the rotating shaft 118 until the load block 119 is aligned with the feed channel 100.

[0045] like Figure 1 The lens feeding device includes a second vibratory plate 102 and a second feed channel 200 connected to the second vibratory plate 102, such as... Figure 4 The lens mounting mechanism 20 includes a positioning rail 21 located below the feed channel 100, an upper baffle 22 located on the feed channel 100, and a cylinder assembly 23. The upper baffle 22 has a connected chain inlet 221 and a chain outlet. The feed channel 100 passes through the chain inlet 221 and the chain outlet in sequence. The positioning rail 21 is connected to the second feed channel 200. The lens enters the positioning rail 21 through the second feed channel 200. The positioning rail 21 is located below the feed channel 100 so that the lens is aligned with the fastening position on the chain. The feed channel 100 and the positioning rail 21 are hollow so that the cylinder assembly 23 can push the lens out to fasten it with the corresponding fastening position. The chain with the lens installed is sent out from the chain outlet and passes through the first drag mechanism 30. The first drag mechanism 30 can drag the chain to step along the feed channel 100. The first drag mechanism 30 drags the chain to step by one assembly distance. After each chain fastening operation is completed, it will step by one assembly distance.

[0046] like Figure 5The first drag mechanism 30 and the second drag mechanism 80 have the same structure. The first drag mechanism 30 includes a finger cylinder 31 and a second rodless cylinder 32 that can reciprocate along the feed channel 100. The finger cylinder 31 is disposed on the feed channel 100 to clamp / release the chain, and the second rodless cylinder 32 is disposed above the finger cylinder 31 to drive the finger cylinder 31 to reciprocate. The specific operation mode of the first drag mechanism 30 is as follows: the finger cylinder 31 first clamps the chain, the second rodless cylinder 32 slides forward one step, the finger cylinder 31 releases the chain and slides back to its original position through the second rodless cylinder 32.

[0047] The soldering device 40 includes a soldering channel for passing through the lamp board 300, and soldering fixtures 41, soldering guns 42, and brushing devices 43 arranged on both sides of the soldering channel. A first mold-passing fixture 201 is provided in front of the soldering fixture 41 to detect the size of the lamp board 300. The lamp board 300 with soldered lamp beads is wound into a first reel 91. The lamp board 300 passes through the first mold-passing fixture 201 and the soldering fixture 41 around the first guide wheel group 93. The second dragging mechanism 80 drags the lamp. With the forward motion, the pads on the lamp board 300 stop at the soldering fixture 41 to perform soldering. The cylinder drives the solder gun 42 to move downward to the pads, and the solder wires on both sides are automatically fed. The solder paste overflows onto the pads on both sides and covers the pads to complete the soldering. Then, the cylinder drives the solder gun 42 to rise. After the second dragging mechanism 80 drags the lamp strip forward a few steps, the pads on the lamp board 300 are dragged to the bottom of the brushing device 43. The brushing device 43 is used to clean the pads back and forth.

[0048] For example Figure 8 The pressing device 50 includes an upper pressing mold 51 and a lower pressing mold 52 that are arranged opposite to each other and can be closed. A pressing channel for the passage of the lamp panel 300 is formed between the upper pressing mold 51 and the lower pressing mold 52. The pressing device 50 presses the lamp panel 300 into shape. Specifically, the upper and lower pressing molds 52 are pushed by cylinders to close and press the lamp panel 300 into shape. When the upper and lower pressing molds 52 are about to close, the finger cylinders 31 at both ends release the lamp panel 300 that is clamped. When the upper and lower molds close, the lamp panels 300 at both ends move towards the pressing molds to form the shape. At this time, the upper and lower pressing molds 52 are in the closed state. The second dragging mechanism 80 performs a moving action, moving a certain distance. After the finger cylinders at both ends clamp the lamp panel 300 again, the upper and lower pressing molds 52 open. The second dragging mechanism 80 performs a reset action, returning to the pressing position of the lamp panel 300. The subsequent actions are repeated as described above. The second guide wheel group 94 is set between the slope pressing device 50 and the lamp panel fastening mechanism 60. After the slope is pressed, the lamp panel 300 enters the lamp panel fastening mechanism 60 through the second guide wheel group 94.

[0049] like Figure 8The light panel fastening mechanism 60 includes a light panel channel for passing the light panel 300 and the chain. The light panel fastening mechanism 60 includes a pressure roller 61 set directly above the material channel 100. The pressure roller 61 is provided with a groove 62. There can be multiple pressure rollers 61, which can achieve a good pressing effect. A light panel channel is formed between the pressure roller 61 and the material channel 100. The light panel 300 is located between the pressure roller 61 and the material channel 100. When the second dragging mechanism 80 steps forward, the pressure roller 61 rotates with the dragging of the chain to fasten the positioning hole of the light panel 300 with the positioning post of the chain, and the groove 62 is pressed onto the slope formed by stamping on the light panel 300. The backplate feeding device includes a third vibratory plate 103 and a third material channel 104 connected to the third vibratory plate 103. The backplate fastening mechanism 70 includes a pin guide rail 71, a suction fixture 76, a fifth cylinder 72, a sixth cylinder 73, and a seventh cylinder 74. Multiple pins 75 are distributed on the pin guide rail 71. The chain of the lamp plate 300 is inserted into the inner side of the forming slope by the pins 75. The pins 75 play a role in tensioning the lamp plate 300 to prevent the holes of the lamp plate 300 from not aligning with the chain positioning posts. The chain of the lamp plate 300 with the pins 75 inserted enters the pin guide rail 71, and the backplate fastening action is performed on the pin guide rail 71. Specific method: The back plate flows into the third material channel 104 via vibration from the third vibrating plate 103. The third material channel 104 is located between the fifth cylinder 72 and the sixth cylinder 73 and is connected to the fifth cylinder 72. The fifth cylinder 72 is located on the side of the pin guide rail 71, and the seventh cylinder 74 is located on the other side of the pin guide rail 71. The sixth cylinder 73 pushes out to push the back plate under the suction fixture 76 so that the suction fixture 76 can hold the back plate, making it easier for the fifth cylinder 72 to push the back plate to the installation position so that the back plate and the light plate 300 form an installation angle. One end of the back plate is already locked into the locking position on one side of the chain. The seventh cylinder 74 pushes out to lock the other end of the back plate into the locking position on the other side of the chain, thus completing the installation of the back plate. The suction fixture 76 and other actions are then reset. When the pin 75 arrives at the exit end of the pin guide rail 71 110, the small cylinder pushes the pin 75 to the inside of the forming slope, and the pin 75 falls into the storage box. The second over-molding fixture 202 is set between the fastening mechanism of the lamp panel 300 and the second dragging mechanism 80 to perform over-molding detection on the lamp strip. The lamp strip that has completed the back panel installation is wound into the second reel 92 through the second over-molding fixture 202 and the second dragging mechanism 80.

[0050] like Figure 1 , 2 As shown in Figure 7, it also includes a detection lens 95, which is located between the lamp panel fastening mechanism 60 and the second through-molding fixture 202 to inspect the lamp strip.

[0051] The chain fastening mechanism 10, lens mounting mechanism 20, first dragging mechanism 30, soldering device 40, slope pressing device 50, lamp board fastening mechanism 60, back plate fastening mechanism 70, and second dragging mechanism 80 are sequentially distributed along the feed channel 100. After the chain accessories are formed into a chain by the chain fastening mechanism 10, they are automatically moved along the feed channel 100 to the lens mounting mechanism 20 under the drag of the first dragging mechanism 30. Since the positioning track 21 is located below the feed channel 100, the lens on the positioning track 21 can be automatically installed onto the chain by the action of the cylinder assembly 23, without manual installation. Next, the installation... The chain with lenses is automatically moved along the feed channel 100 to the lamp board fastening mechanism 60 under the drag of the first drag mechanism 30. At the same time, the lamp board 300 is dragged by the second drag mechanism 80, passing through the solder channel for soldering, through the beveling channel for beveling, and then entering the lamp board channel to fasten with the chain. Next, it enters the back plate fastening mechanism 70 along the feed channel 100 to complete the back plate fastening and form the lamp strip. After being inspected by the second die 202, the second drag mechanism 80 connects with the lamp strip to simultaneously drag the lamp board 300, chain, and lamp strip along the feed channel 100. Finally, the lamp strip is wound into the second reel 92. In the entire assembly process of the lamp strip, the chain and lamp board 300 are dragged by the first drag mechanism 30 and the second drag mechanism 80, moving automatically along the feed channel 100 to complete the corresponding processes step by step until the lamp strip is assembled, saving manpower and improving production efficiency.

[0052] The present invention also includes an assembly process applied to the above-mentioned automated assembly line, comprising the following steps:

[0053] Step 1: Prepare a pre-fastened spare chain, insert the spare chain into the material channel 100 and run it through the entire material channel 100, and then wind it up to the second reel 92 at the rear end for traction.

[0054] Step 2: The chain accessories are vibrated by the first vibrating plate 101 and enter the guide rail 110 along the first material channel. The macro lens 113 identifies whether the direction of the chain accessories on the guide rail 110 is consistent.

[0055] Step 3: If the direction is consistent, continue to flow into the lower part of the small cylinder 3; if the direction is inconsistent, after being rotated 180° by the rotary cylinder 114, continue to flow into the lower part of the second cylinder 12 (while the rotary cylinder 114 is rotating, the support cylinder 115 pushes out to press the rotated chain accessory, and at the same time the first cylinder 11 pushes out to avoid interference and collision between the incoming chain accessory and the rotating chain accessory).

[0056] Step 4: The first rodless cylinder 111 moves to one end, and the slide cylinder 112 at one end slides upward to make the load block 119 dock with the guide rail 110 on one side. The second cylinder 12 retracts to make the chain accessory fall into the load block 119, and then the slide cylinder 112 slides downward to the initial position.

[0057] Step 5: The first rodless cylinder 111 slides to the middle position at the other end, so that the loading block 119 on the slide cylinder 112 at one end abuts against the material channel 100. At the same time, the slide cylinder 112 at the other end slides upward so that the loading block 119 aligns with the guide rail 110 on the other side to complete the picking action of the chain accessories. The slide cylinder 112 that has slid to the middle rotates around the rotating structure so that the chain accessories on its loading block 119 are aligned with the assembly position of the chain accessories on the material channel 100. The third cylinder 13 pushes downward to fasten the two aligned chain accessories.

[0058] Step 6: The first dragging mechanism 30 drags the chain to the lens mounting mechanism 20, and at the same time the lens enters the positioning track 21 through the lens feeding device. The cylinder assembly 23 pushes out to fasten the lens to the fastening position on the chain.

[0059] Step 7: The first dragging mechanism 30 drags the chain to the lamp board channel; at the same time, the lamp board 300 on the first reel 91 enters the soldering channel for soldering under the drag of the second dragging mechanism 80, enters the slope pressing channel for slope pressing so that a forming slope is formed on the lamp board 300, and enters the lamp board channel. The lamp board fastening mechanism 60 fastens the lamp board 300 and the chain.

[0060] Step 8: The chain with the light panel 300 attached enters the light strip channel under the drag of the second drag mechanism 80 to attach the back panel and form a light strip. The light strip passes through the second drag mechanism 80 to be wound into the second reel 92.

[0061] In this assembly process, the macro lens 113 identifies whether the direction of the chain components on the guide rail 110 is consistent. If they are inconsistent, they are adjusted by rotating the rotary cylinder 114 and the support cylinder 115, which improves the accuracy of the assembly. Furthermore, while the first rodless cylinder 111 drives the slide cylinder 112 at one end to reciprocate and align with the corresponding guide rail 110 to connect with the incoming material, the slide cylinder 112 at the other end rotates through a rotating structure to align and engage with the chain assembly position on the material channel 100, resulting in high chain engagement efficiency.

[0062] It will be readily understood by those skilled in the art that the above preferred methods can be freely combined and superimposed without conflict.
