DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The electronic component processing and laminating device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 7 As shown, the electronic component processing and film pasting device of the embodiment of the present application may include a device frame (not shown in the figure) and a film pasting mechanism (not shown in the figure).

[0030] A conveyor belt 20 is transversely disposed on the first frame 11 , and the second frame 12 and the third frame 13 are respectively disposed on the first frame 11 .

[0031] The film laminating mechanism is arranged on the first frame 11, and may include a feeding roller 30, a film laminating roller 40 and an auxiliary component 50. The feeding roller 30 and the film laminating roller 40 are arranged laterally above the conveyor belt 20 in sequence, and the feeding roller 30 is arranged on the second frame 12 through a first motor 31.

[0032] It should be noted that the first motor 31 described in this embodiment can drive the feed roller 30 to rotate, so that the feed roller 30 rotates to retract and release the film material 32.

[0033] The film laminating roller 40 is arranged on the third frame 13 through the auxiliary component 50, and the third frame 13 is arranged on the first frame 11. A core shaft 41 runs through the inside of the film laminating roller 40. The core shaft 41 is hollow and has a plurality of through holes 42 thereon. One end of the core shaft 41 is connected to the suction piece 43. The film laminating roller 40 is provided with a plurality of suction holes 44 respectively connected to the corresponding through holes 42.

[0034] It should be noted that the suction member 43 described in this embodiment can be an air pump, a suction fan, etc. The suction member 43 can be connected to the core shaft 41 through a conduit, and can sequentially adsorb the film material 32 on the outside of the film roller 40 onto the surface of the film roller 40 through the conduit, the core shaft 41 and the suction hole 44, thereby helping the film material 32 to remain stable on the film roller 40.

[0035] It should be noted that the bottom height of the film-laminating roller 40 described in this embodiment is equal to the top height of the component 10, so that when the component 10 passes under the film-laminating roller 40, it can be against the film-laminating roller 40 through the film material 32, and when the component 10 moves laterally, it can drive the film-laminating roller 40 to rotate, thereby attaching the film material 32 on the outside of the film-laminating roller 40 to the top surface of the component 10.

[0036] The auxiliary assembly 50 may include a mounting seat 51, a connecting frame 52, two first slides 53 and two second slides 54, wherein one side of the mounting seat 51 is disposed on the third frame body 13, and the other side of the mounting seat 51 is connected to the connecting frame 52. The connecting frame 52 may include a connecting plate 521 and two side plates 522 respectively disposed at both ends of the connecting plate 521, wherein the two side plates 522 are respectively disposed at two symmetrical sides of the film laminating roller 40, and the core shaft 41 is sequentially disposed through the two side plates 522.

[0037] It is understandable that the mounting seat 51 can fix the connecting frame 52 , and the connecting frame 52 can support the film-laminating roller 40 via the core shaft 41 , thereby ensuring the stability of the position of the film-laminating roller 40 .

[0038] The two first slides 53 and the two second slides 54 are slidably disposed on the corresponding side plates 522, wherein an auxiliary roller 60 is movably disposed between the two first slides 53, and the auxiliary roller 60 is movable and contacts the bottom side of the film laminating roller 40. The two second slides 54 are connected by a slide plate 70, on which a cutter 71 is disposed, and a second motor 80 connected to the second slide 54 is disposed on the mounting seat 51.

[0039] It should be noted that the film material 32 on the feed roller 30 described in this embodiment is attached to the outside of the film laminating roller 40 from below the connecting plate 521, and then goes around the outside of the film laminating roller 40 to the bottom of the film laminating roller 40, so that the head end of the film material 32 is placed at the bottom of the film laminating roller 40, and the auxiliary roller 60 can further press the head end of the film material 32 against the outer wall of the film laminating roller 40, which is helpful to ensure the position of the head end of the film material 32, thereby ensuring the control of the starting position of the film laminating of the component 10.

[0040] It should be noted that the longitudinal length of the film laminating roller 40 described in this embodiment is set corresponding to the longitudinal length of the film laminating required for the component 10 .

[0041] It should be noted that the cutter 71 described in this embodiment is retractable and is located in the radial direction of the film roller 40. When the second motor 80 described in this embodiment can drive the second slide 54 to rotate with the film roller 40 as the center, the second slide 54 can drive the slide plate 70 and the cutter 71 to rotate together, so that the cutter 71 can rotate to the bottom of the film roller 40, so that the cutter 71 can move vertically upward and cut the film material 32.

[0042] Specifically, when it is necessary to perform film laminating operation on the components 10 passing through the conveyor belt 20, the positions of the slide plate 70 and the cutter 71 are first controlled by the second motor 80, and the auxiliary roller 60 is made to rest against the head end of the film material 32. In the process of the component 10 moving with the conveyor belt 20, the head end of the component 10 first contacts the auxiliary roller 60. In the process, the component 10 can push the auxiliary roller 60 to move and separate from the head end of the film material 32. The component 10 then contacts the bottom of the film laminating roller 40. At this time, the head end of the film material 32 is placed on the component 10. At this time, the relevant personnel control the suction part 43 to stop running, so that the film laminating roller 40 releases the adsorption of the film material 32, and controls the rotation of the feeding roller 30 by the first motor 31, so that in the process of the component 10 moving, the feeding roller 30 will continue to transport the film material 32 to the film laminating roller 40, and the film laminating roller 40 rotates with the movement of the component 10 and can stick the film material 32 on it to the top of the component 10.

[0043] After the auxiliary roller 60 moves, it can rest against the top surface of the component 10, and the auxiliary roller 60 rotates with the movement of the component 10. The component 10 with the film on the top will pass under the auxiliary roller 60, so the auxiliary roller 60 can perform secondary rolling on the component 10 to ensure that the film material 32 is highly fitted with the component 10.

[0044] When the tail end of the component 10 is located directly below the film laminating roller 40, the relevant personnel controls the second slide 54 to rotate through the second motor 80, so that the slide plate 70 drives the cutter 71 to rotate to directly below the film laminating roller 40. At this time, the sharp end of the cutter 71 extends vertically from the slide plate 70 and cuts off the film material 32 at the tail end of the component 10. At the same time, the relevant personnel controls the suction part 43 to start, and makes the film laminating roller 40 absorb the film material 32 thereon again, so that the head end of the new film material 32 is attached to the outside of the film laminating roller 40.

[0045] When the component 10 moves and leaves the auxiliary roller 60 , the auxiliary roller 60 can move and reset itself, and can place the head end of the new film material 32 against the film laminating roller 40 .

[0046] By repeating the above operation, the components 10 passing on the conveyor belt 20 can be laminated in turn, which effectively eliminates the waste of materials in the laminating process, significantly reduces the production cost, and enhances the continuous operation capacity and overall efficiency of laminating.

[0047] In one embodiment of the present application, Figure 2 As shown, an inner slide rail 511 and an outer slide rail 512 are respectively provided on both sides of the interior of the mounting seat 51. The inner slide rail 511 and the outer slide rail 512 are both arranged in a downward arc shape, and the inner slide rail 511 is arranged coaxially with the film roller 40. One end of the first slide 53 is slidably arranged on the outer slide rail 512, and one end of the second slide 54 is slidably arranged on the inner slide rail 511.

[0048] It should be noted that the auxiliary roller 60 described in this embodiment is weighted. When not subject to external force, the auxiliary roller 60 can slide freely to the lower end of the first slide rail and rest against the bottom of the film laminating roller 40. The auxiliary roller 60 can thus place the head end of the new film material 32 against the bottom of the film laminating roller 40 after the component 10 is filmed, thereby providing a precise starting point for the film laminating operation of the next component 10 and ensuring the smooth progress of the film laminating process.

[0049] It should be noted that the inner slide rail 511 described in this embodiment is located inside the outer slide rail 512, the outer slide rail 512 is the slide rail of the first slide 53, and the inner slide rail 511 is the slide rail of the second slide 54. This makes it possible for the slide track of the first slide 53 and the slide track of the second slide 54 to not interfere with each other in motion, which helps to stabilize the two.

[0050] Furthermore, if Figure 3 , Figure 6 and Figure 7 As shown, the cutter 71 is slidably connected to the slide plate 70, and a plurality of springs 72 are provided between the cutter 71 and the slide plate 70. A connecting rod 711 is provided at one end of the cutter 71. The free end of the connecting rod 711 passes through the connecting frame 52 and is slidably provided on the inner slide rail 511. A protrusion 5111 is extended upward from the lower end of the inner slide rail 511.

[0051] It should be noted that the connecting rod 711 and the second slide 54 described in this embodiment are both provided with a bending portion, so that the two ends of the connecting rod 711 can be connected to the cutter 71 and the inner slide rail 511 respectively, so that the second slide 54 is connected to the inner slide rail 511.

[0052] Specifically, when the relevant personnel control the rotation of the second slide 54 through the second motor 80 and make the slide plate 70 drive the cutter 71 to rotate to the bottom of the film roller 40, under the rebound action of the spring 72, the connecting rod 71 enters the protrusion 5111. During the process, the connecting rod 711 drives the cutter 71 to move vertically upward and cut off the film material 32 at the tail end of the component 10.

[0053] When the second motor 80 drives the second slide 54 to reverse and reset, the connecting rod 711 moves with the second slide 54 and moves from the protruding portion 5111 to the inner slide rail 511 . During the process, the cutter 71 is retracted and the spring 72 is compressed again.

[0054] In one embodiment of the present application, Figure 6 and Figure 7 As shown, a roller 73 is movably provided on the slide plate 70, and the roller 73 slides against the film-laminating roller 40. It is understandable that the roller 73 can rotate with the film-laminating roller 40, thereby further limiting the film material 32 on the film-laminating roller 40 and contributing to the stability of the rotation of the second slide 54.

[0055] In one embodiment of the present application, Figure 4 and Figure 5 As shown, a plurality of grooves 45 are evenly formed in the circumferential direction of the outer side of the film laminating roller 40 , and the suction holes 44 are located in the grooves 45 .

[0056] It should be noted that the grooves 45 described in this embodiment are numerous and have small internal spacing, so that the error produced after the cutter 71 cuts the film material 32 at the tail end of the component 10 is small, which is beneficial to the fit between the film material 32 and the component 10.

[0057] Specifically, when the relevant personnel control the cutter 71 to rotate to just below the film laminating roller 40, the sharpened side of the cutter 71 can vertically enter the corresponding groove 45, cutting off the film material 32 in the process, and the head end of the new film material 32 can be sucked into the corresponding groove 45 by the suction wind in the groove 45, which helps to stabilize the film material 32 on the outside of the film laminating roller 40.

[0058] In one embodiment of the present application, Figure 1 As shown, a fourth frame 14 is provided on the first frame 11, and the fourth frame 14 is located on the other side of the mounting seat 51. The fourth frame 14 is connected to the adjacent side plate 522, and is slidably connected to the adjacent first slide 53 and second slide 54, and the core shaft 41 passes through the fourth frame 14 and is connected to the suction piece 43.

[0059] It is understandable that the fourth frame 14 can further support the connecting frame 52 and facilitate the sliding of the first slide 53 and the second slide 54 .

[0060] In summary, the electronic component processing and film pasting device of the embodiment of the present application can perform film pasting operations on the components passing through the conveyor belt one by one in turn, ensuring that the film material and the components are highly fitted, effectively eliminating material waste in the film pasting process, significantly reducing production costs, and enhancing the continuous operation capability and overall efficiency of the film pasting.
