DETAILED DESCRIPTION

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] Reference Figure 1The automatic assembly equipment of the LED light strip provided in the embodiment of the present application is used to connect multiple LED light panels in series to form an LED light strip, including a frame 1, a panel dividing device 10 arranged on the frame 1 for dividing an integrally formed semi-finished light panel into a plurality of strip-shaped LED light panels along a score line, a conveying device 20 arranged on one side of the panel dividing device 10 for conveying the LED light panel, a fixture recycling device 30 arranged next to the conveying device 20 for conveying the LED light panel, a wire cutting device 40 arranged next to the fixture recycling device 30, a welding device 50 for welding the wire to the LED light panel, a convex mirror panel automatic feeding device 60 for placing the convex mirror panel on the LED light panel, and an injection mold 70 for injection molding the convex mirror panel and the LED light panel into one piece.

[0052] In the present application, the panel dividing device 10 divides the semi-finished light board into several strip-shaped LED light boards along the score line, the conveying device 20 conveys the LED light board to the fixture of the fixture recycling device 30 and places it on the LED light board, the wire cutting device cuts the rolled wire into a preset length and places it on the LED light board, the welding device 50 welds the ends of the wires on adjacent LED light boards, and the convex mirror board automatic feeding device 60 transports the convex mirror board to the LED light board and injection molds it into one piece through an injection mold. In this process, the fixture is detached from the LED light board before injection molding and returned for recycling using the fixture circulation device 30. The assembly process of the LED light strip is fully automated, with high production efficiency and low cost, and the accuracy is also improved in the welding and cutting processes, thereby improving the product yield.

[0053] Specifically, refer to Figures 2 to 5 The panel separation device 10 includes a platform 11 with a receiving groove (not numbered in the figure), a feed box 12 arranged on the platform 11 and connected to the receiving groove, two support structures 13 arranged on both sides of the feed box 12 for supporting or releasing the semi-finished light boards 16 stacked in the feed box 12, a first pushing structure 14 arranged on one side of the feed box 12 for pushing the semi-finished light board 16 dropped into the receiving groove forward, and a stamping structure 15 arranged in front of the feed box 12 and above the platform 11 for stamping and separating the semi-finished light board 16 pushed by the first pushing structure 14 into a plurality of strip-shaped LED light boards.

[0054] In this embodiment, the semi-finished lamp boards 16 are stacked in the feed box 12, and the two supporting structures 13 release the semi-finished lamp boards 16 one by one. The semi-finished lamp boards 16 that fall into the accommodating grooves are pushed forward to the bottom of the stamping structure 15 by the first pushing structure 14, and are stamped and separated into a number of strip-shaped lamp boards by the stamping structure 15. Such an automatic panel separation device has a simple structure, a high degree of automation, improves production efficiency, and saves labor costs.

[0055] Specifically, the feed box 12 is in the shape of a rectangular box having a receiving cavity, the size of which matches the size of the semi-finished lamp board 16 , so that the semi-finished lamp board 16 can be neatly placed in the receiving cavity without being skewed.

[0056] In this embodiment, the support structure 13 is divided into two groups, which are respectively arranged on both sides of the feed box 12. Each support structure 13 includes an upper fork 131 and a lower fork 132 stacked up and down, an upper cylinder 133 that drives the upper fork 131 to move horizontally, and a lower cylinder 134 that drives the lower fork 132 to move horizontally. The upper cylinder 133 and the lower cylinder 134 move in opposite directions, thus driving the upper fork 131 and the lower fork 132 to move in opposite directions. The two upper forks 131 of the two support structures 13 move synchronously and in opposite directions, and the two lower forks of the two support structures 13 move synchronously and in opposite directions. Specifically, when supporting, the upper forks 131 on both sides are respectively inserted into the top of the bottom semi-finished light board 16 and support the second-to-last semi-finished light board 16, while the lower forks on both sides are respectively inserted into the bottom of the bottom semi-finished light board 16 to support it. When releasing the bottom semi-finished light board 16, the two lower cylinders 134 drive the two lower forks to move outwards and withdraw them respectively. The bottom semi-finished light board 16 has no supporting function and falls into the receiving groove of the lower platform 11, while the second-to-last semi-finished light board 16 is still It is supported by the two upper forks 131 and will not fall. The two lower cylinders 134 then drive the two lower forks to move inward. At the same time, the two upper forks 131 are pulled outward under the drive of the two upper cylinders 133. At this time, the second-to-last semi-finished light board 16 falls onto the two lower forks and is supported by the two lower forks. Then the two upper forks 131 are inserted inward under the third-to-last semi-finished light board 16 under the drive of the two upper cylinders 133. The upper forks 131 and the lower forks repeatedly move in opposite directions, thereby releasing the semi-finished light boards 16 one by one into the receiving grooves of the platform 11.

[0057] In this embodiment, the distance between the upper fork 131 and the lower fork matches the thickness of the semi-finished light board 16. In this way, the upper fork 131 and the lower fork can support the semi-finished light board 16 well.

[0058] Specifically, Figure 4 The support structure 13 includes an L-shaped upper connecting plate 135 and an L-shaped lower connecting plate 136, and the upper connecting plate 135 and the lower connecting plate 136 are stacked. The upper connecting plate 135 is upright, the piston of the upper cylinder 133 is connected to the vertical plate of the upper connecting plate 135, the upper fork 131 is located at the horizontal plate end of the upper connecting plate 135, and the lower connecting plate 136 is inverted, the piston of the lower cylinder 134 is connected to the vertical plate of the lower connecting plate 136, and the lower fork is located at the horizontal plate end of the lower connecting plate 136. As shown in the figure, such a structure makes the connection between the upper cylinder 133, the lower cylinder 134 and the upper connecting plate 135, the lower connecting plate 136 tighter, and the structure is more reasonable, and the operation is more stable.

[0059] Reference Figure 2 and Figure 3 The first push-up structure 14 is a cylinder, and the end of the piston rod of the cylinder is provided with a push plate (not shown in the figure). The push plate is used to better push the semi-finished lamp panel 16 forward.

[0060] In this embodiment, the stamping structure 15 includes a first bracket 151, an upper stamping assembly 152 disposed on the first bracket 151 and movable up and down, and a backing plate assembly 153 facing the upper stamping assembly 152 and located in the receiving groove. After the semi-finished light board 16 is pushed into the receiving groove, under the joint action of the upper stamping assembly 152 and the backing plate assembly 153, it is divided into a plurality of strip-shaped LED light boards along the scoring line.

[0061] Specifically, refer to Figure 5 In this embodiment, the pad assembly 153 includes a bottom plate 1531, multiple groups of lower movable plates 1532 arranged on the bottom plate 1531, and a vacant slot 1533 arranged at the bottom of each group of lower movable plates 1532, each group of lower movable plates 1532 includes at least two lower movable plates (three lower movable plates are shown in the figure), and the vacant slot 1533 has a step. The upper stamping assembly 152 includes a top plate 1521, multiple groups of upper movable plates 1522 arranged on the top plate 1521, and a driving member 1523 that drives the top plate 1521 to move up and down. Specifically, the driving member 1523 is also a cylinder. Each group of upper movable plates 1522 includes at least two upper movable plates (three upper movable plates are shown in the figure), and the top plate 1521 is provided with at least two pushers (not shown in the figure) that respectively drive at least two upper movable plates to move downward to different strokes. When dividing the panels, the cylinder drives the top plate 1521 and multiple groups of upper movable plates 1522 to move downward to stamp the semi-finished lamp board 16. The three LED lamp boards on the semi-finished lamp board 16 move downward to the first position of the vacant slot 1533 along with the lower movable plate, and then the pushing member on the top plate 1521 continues to push the upper movable plate, so that the corresponding LED lamp board and the lower movable plate continue to move downward to the step. In this way, adjacent LED lamp boards are staggered and separated, thereby separating several small lamp boards on the entire semi-finished lamp board 16 along the score line.

[0062] Reference Figures 6 to 8The transport device 20 includes a rotating motor 21 disposed above the platform 11, a rocker arm 22 disposed on the rotating motor 21, and a transport fixture 23 disposed on the rocker arm 22. When the rotating motor 21 rotates, the rocker arm 22 is driven to move, thereby driving the transport fixture 23 to move, and is used to transport the LED light panel from the platform 11 to the fixture of the next station. The transport fixture 23 includes a fixture bracket 231, a first guide rod 232 and a second guide rod 233 disposed in parallel on the fixture bracket 231, a plurality of first sliders 234 disposed on the first guide rod 232, a suction nozzle 235 disposed at the bottom of each first slider 234, and a toggle device 236 disposed on the second guide rod 233. Among them, a connecting block 237 is provided between several adjacent two first sliders 234 among the multiple first sliders 234, and the connecting block 237 is provided with a connecting groove 238 parallel to the first guide rod 232. At least one first slider 234 among the two adjacent first sliders 234 is connected to the connecting block 237 through a connecting member such as a screw (not shown in the figure) located in the connecting groove 238. The toggle device 236 is connected to the first slider 234 away from the rocker arm 22, and the toggle device 236 is connected to a driving device (not shown in the figure) and moves along the second guide rod 233 under the drive of the driving device to adjust the spacing between the multiple first sliders 234.

[0063] In order to improve production efficiency, in a production line, generally multiple light strips are welded at the same time, and each light strip is composed of multiple LED light panels connected in series, and the spacing between adjacent light strips is different, that is, the spacing between the accommodation positions for placing LED light panels on the welding fixture is different. When the light panel is placed on the platform 11 before picking up, the multiple LED light panels are arranged horizontally and closely. Therefore, before using the transport fixture 23 to pick up the LED light panel, the forward movement of the toggle device 236 (close to the rocker arm 22) is used to toggle the first slider 234 so that the multiple first sliders 234 are close to each other, so that each suction nozzle 235 corresponds to the position of each LED light panel for picking up the LED light panel. When the picking is completed, the spacing between the first sliders 234 is opened by the reverse movement of the toggle device 236 (away from the rocker arm 22), so that the suction nozzles 235 on each first slider 234 match the spacing of the accommodation positions on the welding fixture, so as to facilitate the placement of the picked LED light panel on the welding fixture. In the process of moving the first slider 234, since the adjacent first sliders 234 are connected by the connecting blocks 237, and there is a connecting groove 238 between the connecting blocks 237, at least one connecting member on the first slider 234 is located in the connecting groove 238. In this way, the distance between the adjacent sliders is shortened or lengthened by the sliding of the connecting member in the connecting groove. The above-mentioned transport structure makes the picking of the LED light board fully automated, greatly improves the work efficiency and accuracy, and saves labor costs.

[0064] Specifically, in this embodiment, the shifting device 236 includes a slide 2361 sleeved on the second guide rod 233, and a first shifting block 2362 fixed to the side wall of the slide 2361. The first shifting block 2362 is fixedly connected to the side wall of the slider away from the rocker arm 22. Figure 6 As shown, the first shift block 2362 is fixedly connected to the first slider 234 at the rightmost end. When the first shift block 2362 moves close to the rocker arm 22 under the drive of the slide 2361, the first shift block 2362 is used to shift the first slider 234 at the rightmost end. Through the action of the connecting block 237 between adjacent first sliders 234, multiple first sliders 234 are gradually brought together and finally pressed together. When moving in the opposite direction, adjacent sliders 2361 are pulled apart. In this embodiment, the driving device is a cylinder, that is, the movement of the slider 2361 along the second guide rod 233 is driven by the cylinder. The second guide rod 233 plays a guiding role to ensure that the slider 2361 moves horizontally and linearly, thereby improving the stability of the structure.

[0065] Specifically, the first shift block 2362 is L-shaped, one end of the L-shaped first shift block 2362 is fixedly connected to the side wall of the slide seat 2361, and the other end of the L-shaped first shift block 2362 is fixedly connected to the side wall of the first slider 234. This structure is simple and convenient for connecting the first shift block 2362 with the slide seat 2361 and the first slider 234.

[0066] Reference Figure 8 In this embodiment, the lengths of the connection slots 238 of the plurality of connection blocks 237 are different. Since the lengths of the connection slots 238 are different, when the first slider 234 is moved, the spacing between adjacent first sliders 234 can be different, and the spacing is proportional to the length of the connection slot 238.

[0067] In order to prevent the connection blocks 237 from interfering with each other during movement, a plurality of connection blocks 237 are staggered in the up-and-down direction.

[0068] Furthermore, two or more connecting blocks 237 are arranged between two adjacent first sliding blocks 234. Thus, the movement of the first sliding block 234 is made more stable by the two or more connecting blocks 237.

By providing a synchronous belt structure, the movement of the rocker arm 22 is made more stable, and the synchronous belt 222 can ensure the repeatability of the movement of the rocker arm 22, thereby improving production efficiency.

[0070] Reference Figures 9 to 15 In this embodiment, the fixture recycling device 30 is mainly used to recycle the fixtures used in the LED light strip assembly process, which includes a combined fixture 31 composed of a mother fixture 311 and a sub-fixture 312, an assembly line platform 32 for placing and moving multiple combined fixtures 31 to the processing station, a pressing device 33 provided above the assembly line platform 32 for pushing down the sub-fixture 312 to separate the sub-fixture 312 from the mother fixture 311, and a first conveying structure provided below the assembly line platform 32 for receiving the separated sub-fixture 312 and transporting it in reverse to the head end of the assembly line platform 32. 34. A second conveying structure 35 arranged in parallel on one side of the assembly line platform 32 for transporting the separated mother clamp 311 in reverse to the head end of the assembly line platform 32, a shifting device 36 arranged at the end of the assembly line platform 32 for moving the separated mother clamp 311 to the second conveying structure 35, a second pushing structure 37 arranged on one side of the second conveying structure 35 for pushing the mother clamp 311 to the head end of the assembly line platform 32, and a third pushing structure 38 arranged above the first conveying structure 34 for pushing the sub-clamp 312 arriving at the head end of the assembly line platform 32 upward to be combined with the mother clamp 311.

[0071] In this embodiment, the combined clamp 31 composed of the mother clamp 311 and the child clamp 312 moves from the head end to the end of the assembly line platform 32. In this process, the LED light board and the wires are carried through different workstations for processing. When the mother clamp 311 and the child clamp 312 reach the pressing device 33, the pressing device 33 presses the child clamp 312 downward to separate the child clamp 312 from the mother clamp 311. The child clamp 312 returns to the head end position of the assembly line platform 32 under the reverse transportation of the first conveying structure 34, and the mother clamp 311 continues to move forward with the LED light board. Since the wires welded at both ends of the LED light board are supported on the mother clamp 311, the LED light board and the wires will not fall down after the child clamp 312 is separated. At the same time, since the child clamp 312 is vacant, it is also convenient for the lower injection mold to be processed in the next injection molding station. The mold can move upward from the vacant position to close the mold with the upper mold. After the injection molding of the LED light board is completed, it is separated from the mother clamp 311. The mother clamp 311 is pushed by the shifting device 36 to enter the second conveying structure 35 beside the assembly line platform 32. The second conveying structure 35 moves in the opposite direction to transport the mother clamp 311 to the side of the head end of the assembly line platform 32. At this time, the first pushing structure 1470 pushes the mother clamp 311 to the head end of the assembly line platform 32. At this time, the sub-clamp 312 is located below the mother clamp 311. The second pushing structure 80 pushes the sub-clamp 312 upward to make it combine with the mother clamp 311 to form a combined clamp 31. At this time, the LED light board is placed on the combined combined clamp 31 and moves to the next workstation driven by the assembly line platform 32.

[0073] The mother clamp 311 and the sub-clamp 312 are combined by the friction of the ball. Specifically, a receiving hole 313 is correspondingly provided between the inner wall of the square frame of the mother clamp 311 and the outer wall of the sub-clamp 312, and a ball (not shown in the figure) is arranged in the receiving hole 313. The friction between the ball and the receiving hole 313 can ensure the support force of the LED light board when the mother clamp 311 and the sub-clamp 312 are combined, and at the same time, they can be separated smoothly under the action of the pressing device 33.

[0080] Reference Figures 16 to 19 In this embodiment, the wire cutting device is mainly used to cut the rolled wire 41 into a preset length, and at the same time strip the two ends of the cut wire 41 to facilitate welding with the wires 41 of the front and rear light panels when assembling the light strip.

[0081] The wire quick cutting device includes a wire pay-off reel for retracting and releasing the wire 41, a wire pulling device 42 arranged opposite to the wire pay-off reel and used to clamp the end of the wire 41 and move and pull the wire 41, a wire pressing device 43 arranged opposite to the wire pulling device 42, and a cutting assembly 44 arranged between the wire pulling device 42 and the wire pressing device 43 for cutting the wire 41. The cutting assembly 44 includes a first bracket 441, a lower cutting knife assembly 442 arranged on the first bracket 441, and an upper cutting knife assembly 443 arranged opposite to the lower cutting knife assembly 442 and movable up and down along the first bracket 441. The upper cutting knife assembly 443 includes an upper cutting knife near one side of the wire pay-off reel and a wire clamping device 444 near one side of the wire pulling device 42. The upper cutting knife includes two upper stripping knives 4431 and an upper cutting knife 4432 located between the two upper stripping knives 4431. The blade position of the upper cutting knife 4432 is lower than the blade position of the two upper stripping knives 4431.

[0082] In this embodiment, the wire 41 is stored on the wire reel, and one end of the wire 41 is pulled forward by the wire pulling device 42 to unwind, and the cutting assembly 44 is located between the wire pulling device 42 and the wire pressing device 43. When cutting, the two ends of the wire 41 are fixed by the wire pulling device 42 and the wire pressing device 43 respectively. Since the blade position of the upper cutting knife 4432 is lower than the blade position of the two upper stripping knives 4431, when the upper cutting knife assembly 443 drives the upper cutting knife 4432 and the two upper stripping knives 4431 to move downward at the same time, the upper cutting knife 4432 cuts deeper and cuts the wire 41. At the same time, the two stripping knives strip the end of the previous section of the wire 41 and the head end of the next section of the wire 41 that are cut and separated, so that the internal conductive part is exposed, which is convenient for subsequent welding. The above structure is simple, fully automated, and has high production efficiency and low cost.

In this way, the upper cutting edges and the lower cutting edges complete the cutting action at the same time, and the upper stripping edges and the lower stripping edges can also strip the top side wall and the bottom side wall of the wire 41 respectively. Moreover, the simultaneous provision of multiple edges can simultaneously perform cutting and stripping operations on multiple wires 41, further improving work efficiency.

[0084] In this embodiment, the first bracket 441 includes two first columns 4411 arranged opposite to each other and a horizontal plate 4412 connected to the top of the two first columns 4411. As can be seen from the figure, the first bracket 441 also includes a support platform 4413 located between the two first columns 4411. Of course, when the entire wire rapid cutting device is placed on a workbench, the support platform 4413 can also be omitted. A first driving component 445 is vertically arranged on the horizontal plate 4412. The first driving part 35 is a cylinder, and the output end of the cylinder passes through the horizontal plate 4412 and is connected to the upper cutter assembly 443. Specifically, the upper cutter assembly 443 also includes a connecting plate 4433, and the upper cutter 4432 and the two upper peeling knives 4431 are installed at the bottom of the connecting plate 333. The output end of the cylinder drives the upper cutter 4432 and the two upper peeling knives 4431 to move up and down through the connecting plate 333. In order to further improve the balance of the upper cutter assembly 443 during its movement, sliding guide devices 45 are respectively provided between the two ends of the upper cutter assembly 443 and the two columns 311 .

The wire clamping device 444 includes a lower clamping rod 4441 and an upper clamping rod 4442. The two ends of the lower clamping rod 4441 are arranged on the side of the lower cutter assembly 442 facing the wire pulling device 42, so that the lower clamping rod 4441 is also in a stationary state. The two ends of the upper clamping rod 4442 are respectively fixed on the two third sliders 452, and can move up and down with the two third sliders 452 to open or close the clamp relative to the lower clamping rod 4441. That is, when the third slider 452 drives the upper cutter assembly 443 to move downward to complete cutting and stripping, the upper clamping rod 341 is also driven by the third slider 452 to move downward and close with the lower clamping rod 4441 to clamp the end of the previous section of the wire 41 that has been cut. Since the head end of the previous section of the wire 41 is clamped by the wire pulling device 42, the previous section of the wire 41 that has been cut is fixed by the wire pulling device 42 and the wire clamping device 444.

The end of the wire pressing plate 432 close to the cutting component 44 is in a conical structure. The wire pressing plate 432 is arranged on the first horizontal movable platform 431. The wire pressing plate 432 can be horizontally moved under the drive of the first horizontal movable platform 431 to facilitate the wire feeding to the wire pulling device 42.

Before cutting and stripping, the two wire clamping plates 421 are closed to clamp the head end of the wire 41, and when the wire 41 needs to be removed, the two wire clamping plates 422 are opened.

[0091] Furthermore, in this embodiment, the transfer of the wire 41 is also automated, and a mechanical arm 48 is provided beside the wire pulling device 42 to transfer the cut and stripped wire 41 to the next station. When the mechanical arm 48 transfers the previous section of the wire 41, the two clamping plates 422 of the wire pulling device 42 release the head end of the wire 41, and the upper cutter assembly 443 moves upward under the drive of the third slider 452, while the clamping device 444 releases the end of the previous section of the wire 41, and the mechanical arm picks up the wire 41 to the next station.

[0092] The working process of the wire rapid cutting device in this embodiment is as follows: first, the head end of the wire 41 (where the head end has been stripped) passes through the wire entry hole and the wire exit hole of the wire pressing device 43, and is led to the wire pulling device 42 by the lower cutting knife assembly 442 and the upper part of the lower clamping rod 342, and is clamped by the two clamping plates 422 of the wire pulling device 42. The upper cutting knife assembly 443 moves downward under the drive of the third slider 452. At this time, the upper cutting blade cooperates with the lower cutting blade to complete the cutting. The upper stripping knife 4431 on the left side cooperates with the lower stripping knife 4421 to strip the end of the previous section of the wire 41 that has been cut off, and the upper stripping knife edge on the right side cooperates with the lower stripping knife edge to strip the head end of the latter section of the wire 41. 3 moves upward, the wire clamping device 444 releases the end of the previous wire 41, and the two wire clamping plates 422 of the wire pulling device 42 also release the head end of the previous wire 41, the mechanical arm 48 picks up and transports the previous wire 41, the second horizontal moving device 421 of the wire pulling device 42 drives the two wire clamping plates 422 to move toward the cutting assembly 44, at this time, the wire pressing device 43 also moves toward the cutting assembly 44 driven by the first horizontal moving device 431, the two wire clamping plates 422 clamp the wire 41 extending from the wire pressing device 43 and move back to the position in the opposite direction driven by the second horizontal moving device 421, at this time, the cutting assembly 44 performs the next cutting action, repeats the above actions, and continuously completes the rapid cutting and stripping of the wire 41.

When the convex mirror plate is placed on the LED light board, the convex mirrors correspond to the LEDs on the light board.

[0096] In this embodiment, since the convex mirror plate is in the shape of a long strip, when it is transferred from the vibrating material plate 61 to the conveying structure 62, the convex mirror plate is arranged longitudinally, so that it is convenient to move. However, the placement direction of the convex mirror plate and the LED light board is perpendicular, so it is turned by the steering device 63 to make it in the same direction as the LED light board, so that the picking device 64 can pick it up and place it on the LED light board.

The power assembly 74 pulls the lower mold plate 733 along the X direction so that the lower mold plate 733 can move up and down along the plurality of guide posts 732, and each movable pad assembly 75 can move along the Y direction. When the lower mold plate 733 moves up along the guide posts 732, the movable pad assembly 75 moves inwardly and is padded at the bottom of the lower mold plate 733. When the movable pad assembly 75 moves outwardly and is pulled out, the lower mold plate 733 moves down along the guide posts 732. In this embodiment, when the LED light strip is automatically assembled, the LED light board is located on the mother fixture 311 and needs to be separated from the mother fixture 311 after the injection molding is completed. During the injection molding, the lower template 733 moves up along the guide column 732, and the movable pad assembly 75 moves inward and is cushioned at the bottom of the lower template 733, supporting the lower template 733 and facilitating the mold closing and injection molding of the upper mold assembly 72 and the lower mold assembly 73; when the injection molding is completed, the movable pad assembly 75 moves outward and is pulled out, and the lower template 733 moves down along the guide column 732 to avoid the mother fixture 311, facilitating the mother fixture 311 to continue to move forward.

The power assembly 74 includes two pull rods 741 respectively slidably arranged in the first slide grooves, a second cylinder 742 arranged at one end of the two bottom plates 7311, and a first hinge assembly 743 and a second hinge assembly 744. One end of the pull rod 741 is fixedly connected to the second cylinder 742, the other end of the pull rod 741 is hinged to one end of the lower template 733 through the first hinge assembly 743, one end of the second hinge assembly 744 is connected to the piston of the second cylinder 742, and the other end of the second hinge assembly 744 is hinged to the other end of the lower template 733. That is, the two ends of the lower template 733 are respectively connected to the pull rod 741 and the piston of the second cylinder 742 through the first hinge assembly 743 and the second hinge assembly 744. When the piston of the second cylinder 742 moves outward, the lower template 733 is pulled outward through the second hinge assembly 744, and the other end of the lower template 733 pushes the pull rod 741 through the first hinge assembly 743 to move outward as well, and the lower template 733 moves down along the guide column 732. Similarly, when the piston of the second cylinder 742 moves inward, the second hinge assembly 744 and the first hinge assembly 743 are retracted inward, and the lower template 733 moves up along the guide column 732.

[0099] Specifically, the first hinge assembly 743 includes a first hinge 7431 and a first upper hinge shaft 7432 and a first lower hinge shaft 7433 respectively horizontally penetrating the top and bottom ends of the first hinge 7431, the two ends of the first upper hinge shaft 7432 are respectively rotatably connected to the lower template 733, the two bottom plates 7311 are respectively provided with strip holes (not numbered in the figure), and the two ends of the first lower hinge shaft 7433 are respectively rotatably connected to the two strip holes.

[0100] Specifically, the second hinge assembly 744 includes a second hinge 7441 and a second upper hinge shaft 7442 and a second lower hinge shaft 7443 respectively passing horizontally through the top and bottom ends of the second hinge 7441, the two ends of the second upper hinge shaft 7442 are respectively rotatably connected to the lower template 733, the two ends of the second lower hinge shaft 7443 are respectively rotatably connected to the two pull rods 741, and the piston of the second cylinder 742 is connected to the middle of the second lower hinge shaft 7443. In this way, the piston of the second cylinder 742 pulls the second lower hinge shaft 7443 when pulling and pushing, thereby driving the first upper hinge shaft 7442 to rotate, so that the lower template 733 moves downward along the guide column 732.

[0101] In this embodiment, each movable pad assembly 75 includes a third cylinder 751 and a fourth slider 752 driven by the third cylinder 751. A second slide groove 7331 is provided on the bottom plate 7311, and the fourth slider 752 is slidably arranged in the second slide groove 7331. When the lower mold plate 733 moves upward along the guide column 732 under the action of the power assembly 74, the fourth slider 752 moves inward under the push of the third cylinder 751 and is arranged at the bottom of the lower mold plate 733. In this way, the fourth slider 752 supports the lower mold plate 733, so that the lower mold plate 733 can withstand the pressure of the upper mold assembly 72 when the lower mold plate 733 is molded with the upper mold assembly 72 for injection molding. When the mold closing is completed, the fourth slider 752 moves outward to the outside of the lower template 733 under the pull of the third cylinder 751. At this time, the lower template 733 moves downward along the guide column 732 under the action of the above-mentioned power component 74, and the lower template 733 drops back to its original position. In this way, the lower template 733 avoids the female clamp 311 on the automatic assembly production line of the LED light strip, making it convenient for the female clamp 311 to continue to move forward.

[0102] In this embodiment, the fourth slider 752 has an L-shaped cross section, and includes a horizontal portion and a vertical portion, wherein the horizontal portion is slidably disposed in the second slide groove 7331, and the vertical portion supports the lower template 733. The height of the horizontal portion is equal to or less than the depth of the second slide groove 7331, so that when the vertical portion is withdrawn to be located outside the lower template 733, the horizontal portion is still located in the second slide groove 7331, and the horizontal portion does not protrude from the second slide groove 7331, so as not to interfere with the lower template 733, and also avoids completely withdrawing the horizontal portion from the second slide groove 7331.
