Description

suction heads, adsorption components and FPC stripping equipment Technical Field

[0001] This application relates to the technical field of FPC stripping, and more particularly to a suction head, an adsorption assembly, and an FPC stripping device. Background Technology

[0002] FPC sheets consist of a transparent base film and multiple FPCs (flexible printed circuit boards) mounted on the base film. The FPCs need to be peeled off from the base film. The traditional peeling method involves sticking the FPC sheet to transparent tape and then using a label peeler to peel the FPC onto a Teflon non-stick platform for subsequent adsorption and retrieval.

[0003] However, unlike the more regular rectangular labels, FPCs come in various shapes. Some FPCs have a longer main body, or some may have one or more long branches. In addition, the surface of the Teflon anti-stick platform is relatively rough. This causes the longer parts of the FPC to easily twist and deform when pushed on the Teflon anti-stick platform, which affects the stability of subsequent adsorption and material handling. In some cases, the FPC may even bounce off the bottom film and fly away, resulting in material waste.

[0004] In addition, due to the complex shape of FPC, if a conventional suction nozzle is used to adsorb and peel it off from the transparent base film, it is easy to cause the FPC to be twisted and deformed, which is not convenient for subsequent FPC attachment.

[0005] Therefore, it is necessary to provide a suction head that can reliably peel FPC off a transparent base film, an adsorption assembly having the suction head, and an FPC peeling device. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a suction head that can reliably peel FPC off a transparent base film, an adsorption assembly having the suction head, and an FPC peeling device.

[0008] In a preferred embodiment, the first surface and the second surface are located on opposite sides of the suction head.

[0009] In a preferred embodiment, the suction head further includes a third surface connecting the first surface and the second surface, the third surface also having a second connecting hole communicating with the first connecting hole, the second connecting hole being used for installing fasteners.

[0010] In a preferred embodiment, the suction head has a plurality of side surfaces located between the first surface and the second surface, and an extension hole is formed on at least one side surface to form the air cavity. The extension direction of any of the extension holes is parallel to the second surface, and the opening of the extension hole is sealed.

[0011] This utility model also provides an adsorption component, including the suction head described in any of the above embodiments, and the adsorption component further includes a first connecting tube detachably connected to the first connecting hole.

[0012] In a preferred embodiment, the adsorption assembly further includes a second connecting tube extending into the first connecting tube, a third connecting tube connected to the second connecting tube, and an elastic member sleeved on the outer periphery of the second connecting tube; one end of the elastic member abuts against the first connecting tube, and the other end abuts against the third connecting tube.

[0030] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.

[0031] In actual production, there is an FPC sheet 90 as shown in Figure 1, which includes a transparent base film 91 and multiple FPCs 92 disposed on the transparent base film 91. It is necessary to peel each FPC 92 off from the transparent base film 91.

[0032] Referring to Figures 2 and 3, one embodiment of this utility model provides a suction head 10, which is used to adsorb FPC, for example, for peeling, transferring, or attaching FPC. The suction head 10 has an internal air chamber 11. A first connecting hole 12 is provided on the first surface 15 of the suction head 10, communicating with the air chamber 11. The first connecting hole 12 is used for mounting the suction head 10, allowing it to be connected to an air tube structure. A groove 13 is provided on the second surface 16 of the suction head 10, the shape of which corresponds to the shape of the FPC. The bottom surface 131 of the groove 13 has multiple air holes 14, each communicating with the air chamber 11.

[0033] In this embodiment, the suction head 10 can be pressed against the FPC to make the FPC fit into the groove 13. The multiple air holes 14 provided on the bottom surface 131 of the groove 13 simultaneously generate suction so that each part of the FPC is adsorbed at the same time. During this process, the FPC is not easily twisted or deformed, so it can be peeled off from the transparent base film 91 relatively stably.

[0034] In a preferred embodiment, the depth of the groove 13 is the same as the thickness of the FPC, or the depth of the groove 13 is slightly less than the thickness of the FPC.

[0035] It is understandable that the relative positions of the second surface 16 and the first surface 15 can be varied; for example, they can be arranged adjacently or relative to each other.

[0036] In a preferred embodiment, the first surface 15 and the second surface 16 are located on opposite sides of the suction head 10, making the connection structure of the suction head 10 simpler and more practical. In this embodiment, the top of the suction head 10 can be connected to an air tube, and the bottom of the suction head 10 can adsorb a flat FPC.

[0037] Furthermore, the suction head 10 also includes a third surface 17, which connects the first surface 15 and the second surface 16. The third surface 17 is also provided with a second connecting hole 18, which communicates with the first connecting hole 12. The second connecting hole 18 is used to install fasteners. In this embodiment, when the suction head 10 is connected to the air tube structure through the first connecting hole 12, the fastener can pass through the second connecting hole 18 and extend into the first connecting hole 12 to fix the air tube structure to the suction head 10.

[0038] In a preferred embodiment, the suction head 10 has a plurality of side surfaces located between the first surface 15 and the second surface 16, and an extension hole 19 is formed on at least one side surface to form an air cavity 11. The number, extension length, and extension direction of the extension holes 19 can be adapted to the actual structure of the FPC. For example, when the suction head 10 is used to adsorb the FPC shown in FIG. 1, two intersecting extension holes 19 with mutually perpendicular extension directions can be formed.

[0039] It is understood that the structure of the extension hole 19 on the suction head 10 is shown in the accompanying drawings of this application. However, in actual applications, the opening of the extension hole 19 is sealed regardless of whether it penetrates the other end of the suction head 10, so as to avoid air leakage and reduce the suction force of the suction head 10.

[0040] Preferably, the extension direction of any extension hole 19 is parallel to the second surface 16.

[0041] One embodiment of the present invention provides an adsorption component 100, which includes the suction head 10 in any of the above embodiments, and further includes a first connecting tube 20, which is detachably connected to a first connecting hole 12.

[0042] In this embodiment, the groove 13 of the suction head 10 is designed to correspond to the shape of the PFC. Therefore, a specific model of suction head 10 can only adsorb one specific shape of FPC. However, the first connecting tube 20 and the first connecting hole 12 are detachably connected, so that the adsorption assembly 100 can replace different styles of suction heads 10, thereby adsorbing various corresponding shapes of FPC. It has wide applicability and low replacement cost.

[0043] In a preferred embodiment, referring to Figures 4-6, the adsorption assembly 100 further includes a second connecting tube 30, a third connecting tube 40, and an elastic element 50. The second connecting tube 30 extends into the first connecting tube 20, the third connecting tube 40 is connected to the second connecting tube 30, and the elastic element 50 is sleeved on the outer periphery of the second connecting tube 30, with one end of the elastic element 50 abutting against the first connecting tube 20 and the other end abutting against the third connecting tube 40.

[0044] In this embodiment, when the suction head 10 presses down to insert the FPC into the groove 13, the elastic element 50 can provide a certain buffer, which can ensure that the FPC can fully fit the bottom surface 131 of the groove 13, while avoiding excessive pressure from the suction head 10 and damage to the FPC.

[0045] It is understandable that the second connecting pipe 30 and the third connecting pipe 40 can be set separately and fixed together, or they can be set as one piece.

[0046] Furthermore, the adsorption assembly 100 also includes a limiting rod 60, which extends radially through the second connecting pipe 30. The first connecting pipe 20 is provided with a first extension groove 21, which extends axially along the first connecting pipe 20. The limiting rod 60 extends into the first extension groove 21.

[0047] Furthermore, the first connecting pipe 20 also includes a second extension groove 22 and a third extension groove 23. The second extension groove 22 extends circumferentially along the first connecting pipe 20, and one end of the second extension groove 22 is connected to the end of the first extension groove 21 opposite to the third connecting pipe 40. The third extension groove 23 is connected to the other end of the second extension groove 22. The third extension groove 23 extends axially along the first connecting pipe 20 toward the third connecting pipe 40 and penetrates the end face of the first connecting pipe 20.

[0048] In this embodiment, the limiting rod 60 can be slid in the first extension groove 21, the second extension groove 22, and the third extension groove 23 sequentially by lifting the first connecting tube 20, rotating the first connecting tube 20, and releasing the first connecting tube 20 downward, so that the limiting rod 60 is separated from the first connecting tube 20. This allows the first connecting tube 20 and the suction head 10 to be disassembled together. When installing other types of suction heads 10, installation can be completed simply by rotating the first connecting tube 20 fixed to the suction head 10. In this way, different types of suction heads 10 can be replaced without the aid of a screwdriver.

[0049] Preferably, both ends of the limiting rod 60 pass through the second connecting pipe 30, and the first extension groove 21, the second extension groove 22 and the third extension groove 23 on the first connecting pipe 20 are provided in two sets, and the two sets are symmetrical.

[0050] In a preferred embodiment, to improve the airtightness between the first connecting tube 20 and the suction head 10, the adsorption assembly 100 further includes a sealing ring 70 located in the first connecting hole 12. The first connecting tube 20 has an annular clearance space 24 at one end extending into the first connecting hole 12. When the first connecting tube 20 is installed in the first connecting hole 12, the sealing ring 70 is located in the annular clearance space 24.

[0051] One embodiment of this utility model provides an FPC stripping device, which includes the adsorption component 100 in any of the above embodiments.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
