Description

Technical Field

[0001] This application relates to the field of FPC production equipment technology, and in particular to a quick-attachment tooling for FPC reinforcing plates. Background Technology

[0002] Flexible printed circuit boards (FPCs), also known as flexible circuit boards or flexographic circuit boards, are printed circuit boards made with polyimide or polyester film as the substrate. Due to their high reliability and excellent flexibility, FPCs occupy an important position in the electronics industry and are often simply referred to as flexible boards. These circuit boards offer significant advantages such as high wiring density, light weight, and thinness, effectively meeting the development needs of modern electronic products for miniaturization, lightweighting, and high integration.

[0003] During the FPC production process, reinforcing plates need to be attached to the FPC. FPC reinforcing plates are a type of reinforcing material used in flexible printed circuit boards (FPCs). Their main function is to increase the strength, hardness, and abrasion resistance of the FPC in specific areas to meet different application requirements. The reinforcing plates arrive in small quantities and are arranged haphazardly, so they must first be manually bonded one by one to the film to ensure neat alignment. Then, the film is placed on an automated machine, where a robotic arm picks up the corresponding reinforcing plate and installs it onto the corresponding FPC.

[0004] The film material is mostly polyethylene terephthalate (PET), and the resulting film is transparent. The adhesion between the FPC reinforcing plate and the film is mainly due to the following principles: 1. Van der Waals forces exist between molecules. When the molecular distance between the reinforcing plate and the film surface is close enough, van der Waals forces will attract them to each other. 2. Electrostatic attraction: During production or use, the FPC reinforcing plate and film may acquire different types of charges due to friction, contact, etc., thus generating electrostatic attraction. 3. Surface energy: All surfaces have a certain surface energy; the lower the surface energy, the more stable the surface. When the FPC reinforcing plate and film are in contact, in order to reduce the total surface energy of the system, they tend to increase the contact area, thus producing an adhesion phenomenon.

[0005] Regarding the aforementioned technologies, currently, the bonding of FPC reinforcing plates and films mainly relies on manual labor. Due to the lack of corresponding positioning fixtures and other auxiliary tools, positioning deviations and uneven bonding are prone to occur, thus requiring improvement. Utility Model Content

[0006] To facilitate the bonding of FPC reinforcing plates and films, this application provides a quick bonding fixture for FPC reinforcing plates.

[0007] The FPC reinforcing plate quick-adhesion fixture provided in this application adopts the following technical solution:

[0008] A quick-attachment fixture for FPC reinforcing plates includes a workbench, a placement plate, a positioning plate, and a winding assembly. The placement plate is horizontally placed on the workbench and is used to place the FPC reinforcing plate. The positioning plate is placed on the workbench and close to the placement plate. The positioning plate has several positioning grooves for positioning the FPC reinforcing plate.

[0009] The winding assembly is located on one side of the positioning plate and is used to wind the film with the FPC reinforcing plate attached.

[0010] By adopting the above technical solution, during production, workers place the FPC reinforcing plates from the placement plate one by one into the positioning slots. Next, workers stretch and adhere the film to the positioning plate, causing the film and the FPC reinforcing plates to adhere to each other. After adhesion, a winding assembly is used to wind the film, improving uniformity. The entire process eliminates the need for manual pasting of each FPC reinforcing plate onto the film, achieving a uniform adhesion effect.

[0011] Preferably, the depth of the positioning groove is less than the thickness of the FPC reinforcing plate.

[0012] By adopting the above technical solution, the depth of the positioning groove is less than the thickness of the FPC reinforcing plate, which allows the FPC reinforcing plate to be exposed in the positioning groove, so that the film can be better adhered and adsorbed.

[0013] Preferably, the winding assembly includes a base, a spool, and a limiting block. The base is disposed on the worktable, the spool is horizontally arranged and rotatably connected to the base, the spool is used for inserting a drum, and the limiting block is detachably connected to one end of the spool and is used to prevent the drum from falling off the spool.

[0014] By adopting the above technical solution, an external roll is inserted into the shaft, and the roll is used to wind the film. After the roll is installed, a limiting block is inserted into the shaft to prevent the roll from falling off the base. The operator can apply external force to the limiting block to control the rotation of the entire roll and shaft, thereby completing the film winding.

[0015] Preferably, the base includes a first plate and a second plate, the first plate being in contact with the workbench, the second plate being vertically connected to the first plate, and the scroll being rotatably connected to the second plate.

[0016] Preferably, the workbench is provided with a plurality of pins, and the first plate is provided with a plurality of holes, and each pin is inserted into the hole.

[0017] By adopting the above technical solution, each pin is inserted into its respective socket, and the first plate and the worktable are detachably connected by the insertion force. The first plate is constrained by the pins, making it less prone to positional shift on the worktable and improving the stability of the entire winding assembly.

[0018] Preferably, it further includes a lifting block and a lifting cylinder. The second plate has a strip-shaped hole extending through it in the vertical direction. The lifting block is lifted and lowered on one side of the second plate. One end of the roller is rotatably connected to the lifting block through a bearing. The roller passes through the strip-shaped hole. The piston rod of the lifting cylinder is connected to the lifting block and is used to control the movement of the lifting block. The lifting cylinder has a stroke control mechanism.

[0019] By adopting the above technical solution, as the roll continues to wind, the overall thickness of the wound film will continuously increase. Since the vertical distance between the roll and the first plate is fixed, this can easily affect the further winding of the roll. By adding a lifting cylinder and a lifting block, the lifting cylinder can control the lifting and lowering to move vertically upward, thereby driving the entire roll to rise, increasing the vertical distance between the roll and the first plate, so that the film can be wound better.

[0020] Meanwhile, the rotation of the bearing allows the spool to be rotatably connected to the lifting block without affecting the winding of the drum. The slotted hole allows the entire spool to pass through, and when the lifting block moves up and down, the slotted hole makes way for the movement of the spool, avoiding interference.

[0021] Preferably, the limiting block is connected to the scroll by a plug-in connection.

[0022] By adopting the above technical solution, the limiting block and the roll can be detachably connected by plugging. After the upper film of the roll is wound to a certain thickness, the limiting block can be removed and the entire roll can be taken off the roll.

[0023] Preferably, it further includes a quick clamp, which is disposed on the worktable and is used to press the first plate against the worktable.

[0024] By adopting the above technical solution, the quick clamp can press the first plate firmly onto the worktable, improve the stability of the base, and reduce the possibility of the base tipping over.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] (1) By setting up a placement plate, a positioning plate, and a winding assembly, during the production process, the workers first place the FPC reinforcing plates on the placement plate one by one into the positioning slots. Then, the workers stretch the film and attach it to the positioning plate, thereby achieving mutual adsorption between the film and the FPC reinforcing plates. After adsorption is completed, the film is then wound using the winding assembly to ensure that the film is wound neatly and orderly. The entire production process does not require manual pasting of the FPC reinforcing plates onto the film one by one, effectively achieving a good effect of uniform pasting.

[0027] (2) By setting up lifting blocks and lifting cylinders, the vertical distance between the roll and the first plate can be changed so that the film can be wound better.

[0028] (3) By setting up a quick clamp, the quick clamp can press the first plate onto the worktable, improve the stability of the base, and reduce the possibility of the base tipping over. Attached Figure Description

[0036] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0038] This application discloses a quick-attachment fixture for FPC reinforcing plates. (Refer to...) Figure 1 and Figure 2 The bonding fixture includes a worktable 1, a placement plate 2, a positioning plate 3, and a winding assembly 4. The worktable 1, serving as a carrier, is placed horizontally on the ground. The placement plate 2, rectangular in shape, is horizontally and fixedly connected to the worktable 1, and is used to place the FPC reinforcing plate. The positioning plate 3 is fixedly connected to the worktable 1 and close to the placement plate 2. The thickness of the positioning plate 3 is less than or equal to the thickness of the placement plate 2. The positioning plate 3 has several positioning grooves 5, each with a shape adapted to the FPC reinforcing plate. These grooves are spaced apart along the length and width of the positioning plate 3, and are used to position the FPC reinforcing plate. The depth of the positioning grooves 5 is less than the thickness of the FPC reinforcing plate, allowing the FPC reinforcing plate to protrude from the opening of the grooves 5 for better film adhesion and adhesion.

[0039] The winding assembly 4 is located on one side of the positioning plate 3 and is used to wind the film with the FPC reinforcing plate attached. Specifically, the winding assembly 4 includes a base 41, a roller 42, and a limiting block 43. The base 41 is mounted on the worktable 1 and includes a first plate 411 and a second plate 412. The first plate 411 is in close contact with the worktable 1, and the second plate 412 is vertically connected to the first plate 411. The first plate 411 can be fixed to the worktable 1 by a fixed connection, such as welding; or it can be detachably connected to the worktable 1, such as by a plug-in connection. That is, several plugs are fixed on the worktable 1, and several plug holes are correspondingly opened on the first plate 411. Each plug is inserted into its respective plug hole, and the detachment is achieved by the plugging force. To further improve the stability of the connection between the first plate 411 and the worktable 1, several quick clamps 9 can be installed on the worktable 1 to press the first plate 411 onto the worktable 1.

[0040] The spool 42 is horizontally positioned and rotatably connected to the second plate 412, with its axis of rotation perpendicular to the plane of the second plate 412. The spool 42 is used for inserting an external roll, which is used for winding the film. A limiting block 43 is detachably connected to the end of the spool 42 away from the second plate 412. The limiting block 43 is installed at the end of the spool 42 by insertion or snap-fit, and is used to prevent the roll from detaching from the spool 42.

[0041] During production, workers place the FPC reinforcing plates from the placement plate 2 one by one into the positioning slots 5. Next, the workers stretch and adhere the film to the positioning plate 3, causing the film and the FPC reinforcing plates to adhere to each other. After adhesion, workers can apply external force to the limiting block 43 to control the rotation of the entire roll and shaft 42, thereby completing the film winding and improving uniformity. The entire process eliminates the need for manual pasting of each FPC reinforcing plate onto the film, achieving a uniform adhesion effect.

[0042] Combination Figure 3In addition, in some embodiments, a lifting block 7 and a lifting cylinder 8 are also installed on the base 41. A strip-shaped hole 6 is vertically through the second plate 412, and the lifting block 7 is lifted and lowered on one side of the second plate 412. One end of the scroll 42 is rotatably connected to the lifting block 7 via a bearing, and the scroll 42 passes through the strip-shaped hole 6. The lifting cylinder 8 is installed on the first plate 411, and the piston rod of the lifting cylinder 8 is connected to the lifting block 7 to control the vertical up and down movement of the lifting block 7. The lifting cylinder 8 is located below the lifting block 7. In this embodiment, the lifting cylinder 8 has a stroke control mechanism, which can control the cylinder piston rod to stop at a predetermined position to achieve precise mechanical actions (such as clamping, pushing, lifting, etc.) and provide continuous, stable and reliable pressure. Typical stroke control mechanism types include, but are not limited to, mechanical stops, magnetic switches with solenoid valves, and displacement sensors with controllers. These are existing technologies and will not be described in detail here.

[0043] As the roll continues to wind, the overall thickness of the wound film increases. Since the vertical distance between the roll 42 and the first plate 411 is fixed, this can easily affect the further winding of the roll. By adding a lifting cylinder 8 and a lifting block 7, the lifting cylinder 8 can control the vertical movement of the lifting block upwards, thereby driving the entire roll 42 to rise, increasing the vertical distance between the roll 42 and the first plate 411, so that the film can be wound better.

[0044] The implementation principle of the FPC reinforcing plate quick-attachment fixture in this application embodiment is as follows: During the production process, the operator first places the FPC reinforcing plates on the placement plate 2 one by one into the positioning groove 5. Then, the operator stretches the film and attaches it to the positioning plate 3, thereby achieving mutual adsorption between the film and the FPC reinforcing plate. After adsorption is complete, the film is then wound using the winding assembly 4 to ensure that the film winding is neat and orderly. The entire production process eliminates the need for manual attachment of each FPC reinforcing plate to the film, effectively achieving a good effect of uniform adhesion.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
