With the promotion of automation, the protective paper on the components on the FPC is also attached by automatic equipment. In order to prevent the components from being touched and pressed by the pressure head of the equipment, resulting in damage to the components or cracks inside the components, the bottom surface of the pressure head (structure such as Figure 1 ) first suck up the protective paper by suction, and then when it is close to the upper surface of the component (such as Figure 2 ), the vent hole is changed to a blowing method, and the protective paper is blown to the upper surface of the component. In this way, the protective paper cannot be well attached to the upper end of the component, and the excess part cannot be attached and fixed to the FPC (such as Figure 3 As shown), after attachment, it still needs to be manually pressed and fixed, which increases labor costs and affects production efficiency, and is not conducive to automated production.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0037] As described in the background technology, the existing protective paper attaching pressure head still needs to be manually pressed and fixed after the protective paper is attached, which increases labor costs and affects production efficiency, and is not conducive to automated production; at the same time, the insulating high-temperature adhesive tape structure needs to be concavely deformed during the process of pressing down the soft board, which causes the soft board to squeeze the components, which can easily cause damage to the components and affect product quality.
[0038] In order to solve this technical problem, the utility model provides a protective paper attaching jig for components on an FPC, which is applied to the field of FPC processing jigs.
[0039] Specifically, please refer to Figure 4-7 The protective paper attaching jig for the components on the FPC specifically includes a pressing head 1, a groove 2 is provided on the crimping surface of the pressing head 1, an air cavity 3 is arranged inside the pressing head 1, and the air cavity 3 is connected to a plurality of vents 4, the vents 4 are connected to the crimping surface of the pressing head 1, and an air inlet 5 is arranged on one side of the air cavity 3.
[0040] The utility model provides a jig for attaching protective paper for components on an FPC. A groove 2 is provided on the bottom surface of a pressing head 1, and the protective paper 10 to be attached is adsorbed onto the crimping surface of the pressing head 1 by using the vent hole 4. When the pressing head 1 is pressed down onto the surface of the FPC 8, air is blown through the vent hole 4 to apply pressure to the protective paper 10, so that the protective paper 10 is attached to the FPC 8 and wraps the components 9. The protective paper 10 can be attached and fixed to the FPC 8 to prevent the protective paper 10 from detaching. Manual pressing and fixing are not required, thereby improving production efficiency. Moreover, the arrangement of the groove 2 prevents the pressing head 1 from pressing the components 9 during the pressing process, thereby avoiding damage to the components 9 during the attaching process of the protective paper 10, thereby ensuring product quality. The utility model also has a simple overall structure, low manufacturing cost, convenient attachment, easy operation, and convenient automated production.
[0041] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0043] The FPC8 used in this embodiment is a flexible printed circuit board.
[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0045] Example 1
[0046] Please refer to Figure 4-7 , a protective paper attaching jig for components on an FPC is provided, which includes a pressing head 1, which is connected to a lifting structure, and the lifting structure is used to drive the pressing head 1 to rise and fall, so that the bottom surface of the pressing head 1 can be attached to the surface of the FPC8, and a groove 2 is provided on the crimping surface of the pressing head 1, and an air cavity 3 is arranged inside the pressing head 1, and the air cavity 3 is connected to a plurality of vents 4, and the vents 4 are connected to the crimping surface of the pressing head 1, and an air inlet 5 is arranged on one side of the air cavity 3, and the air inlet 5 is connected to an air filling and exhausting device, and the air cavity 3 is pressurized or depressurized by the air filling and exhausting device, so that air is blown or sucked by the vents 4, so as to achieve the purpose of adsorbing and fixing the protective paper 10 and blowing and pressurizing the protective paper 10, so that the protective paper 10 can be attached to the FPC8.
[0047] In order to avoid the bottom surface of the groove 2 from squeezing the component 9 and the side walls of the groove 2 from touching the component 9, the plane size of the groove 2 is not less than the plane size of the component 9, and the depth of the groove 2 is not less than the height of the component 9. Such a structural design allows the groove 2 to wrap around the component 9 when pressed down without contacting the component 9, thereby achieving the purpose of protecting the component 9.
[0048] The vent hole 4 includes a first through hole 41 and a second through hole 42. The first through hole 41 is connected to the bottom surface of the groove 2, and the second through hole 42 is connected to the crimping surface of the pressure head 1 located around the groove 2. The number of the vent holes 4 is freely designed according to the size of the protective paper 10 to ensure that the vent holes 4 can adsorb and fix the protective paper 10. At the same time, the size and shape of the vent holes 4 can also be freely designed and are not limited here. In this example, the vent holes 4 are arranged in two groups, one group is a first through hole 41 arranged at the bottom of the groove 2, and the other group is a second through hole 42 arranged around the groove 2. When taking the protective paper 10, the first through hole 41 absorbs the protective paper 10 and deforms it, so that the protective paper 10 fits with the bottom and the surrounding of the groove 2, and the second through hole 42 is used to suck and fix the surrounding of the protective paper 10. At the same time, when attaching, the second through hole 42 is used to blow air and apply pressure to the protective paper 10, so that the protective paper 10 and the FPC8 are attached and bonded to achieve the purpose of fixation. At the same time, the first through hole 41 blows air and also applies pressure to the protective paper 10, so that the protective paper 10 fits with the upper surface of the component 9, which can better bond and fix the protective paper 10. The entire attaching process does not require manual operation, which greatly improves production efficiency and realizes automated attachment.
[0049] Example 2
[0050] The protective paper attachment jig for the components on the FPC provided in Example 1 is further optimized. Specifically, Figure 8 , 9 As shown, the groove 2 is a conical structure, and the bottom surface size of the groove 2 is larger than the top surface size of the component 9, so as to avoid touching the component 9 as the plane size of the groove 2 decreases during the pressing process. At the same time, the side inclination angle of the groove 2 is 30-75°, and the inclination angle of the side of the groove 2 is adjusted and determined according to the height of the component 9 to be protected. The higher the height of the component 9, the smaller the inclination angle of the side of the groove 2. The setting of the inclined surface leaves a buffer platform for the protective paper 10, which makes it easier for the protective paper 10 to be attached to the groove 2.
[0051] Through the above-mentioned structural design, the groove 2 is set to a conical structure, so that when the protective paper 10 is attached, a certain space is formed between the protective paper 10 and the side of the component 9, and the component 9 can also be wrapped, thereby avoiding the problem of the protective paper 10 falling off and loosening after being attached to the side of the component 9, and the overlap of the protective paper 10 at the corners can be reduced, thereby improving the bonding strength of the protective paper 10, and the inclination angle of the side of the groove 2 can be freely set according to the height of the component 9.
[0052] Example 3
[0053] The protective paper attachment jig for the components on the FPC provided in Example 2 is further optimized. Specifically, Fig.10 , 11As shown, the crimping surface of the pressure head 1 is bonded with a flexible layer 6, which is recessed into the groove 2 and fits with the side wall of the groove 2. The flexible layer 6 is a rubber pad, and of course it can also be other pads, such as cotton pads, spring pads or silicone pads, as long as they can play a flexible buffering role, and the flexible layer 6 is provided with a hole coaxial and of the same size as the vent 4, so that the vent 4 can smoothly perform air suction and blowing. In this example, the flexible layer 6 is preferably a rubber pad, which can play an anti-slip role on the one hand, and can also improve the sealing of the protective paper 10 when it is sucked together on the other hand.
[0054] Through the above structural design, a flexible layer 6 is provided on the crimping surface of the pressure head 1. The provision of the flexible layer 6 prevents accidental crushing when the pressure head 1 contacts the FPC 8 and the components 9, thereby further protecting the FPC 8 and the components 9.
[0055] Example 4
[0056] The protective paper attachment jig for the components on the FPC provided in Example 3 is further optimized. Specifically, Fig.12 , 13 As shown, the crimping surface of the pressing head 1 is provided with a limiting protrusion 7, which is arranged on the periphery of the groove 2, and the inner side surface is in contact with the protective paper 10. The limiting protrusion 7 is an annular structure, that is, the limiting protrusion 7 is along the periphery of the pressing head 1, and the height of the limiting protrusion 7 is not greater than the thickness of the protective paper 10.
[0057] Through the above structural design, the limiting protrusion 7 is used to limit the protective paper 10 to prevent the protective paper 10 from lateral displacement. At the same time, it is also convenient for the pressure head 1 to suck up and fix the protective paper 10, thereby improving the attachment position of the protective paper 10.
[0058] The working principle of the protective paper attachment jig for components on FPC provided by the utility model is as follows: the pressure head 1 is connected to the lifting mechanism on the automation equipment, and the air is sucked by the air filling and exhausting device, so that the pressure head 1 adsorbs the protective paper 10 on the bottom surface of the pressure head 1 and the protective paper 10 is recessed into the groove 2 and fits with the groove 2, and then the pressure head 1 is moved to the top of the FPC 8 to be attached, and the pressure head 1 is moved downward until the pressure head 1 is pressed down to the surface of the FPC 8. At this time, the air filling and exhausting device inflates the air cavity 3 and uses the vent hole 4 to The protective paper 10 is blown and pressurized so that the protective paper 10 is attached to the FPC 8 and wraps the components 9. The protective paper 10 can be attached and fixed to the FPC 8 to prevent the protective paper 10 from detaching. There is no need for manual pressing and fixing, which improves production efficiency. The setting of the groove 2 will not cause pressure on the component 9 during the pressing process, thereby avoiding damage to the component 9 during the attachment of the protective paper 10, ensuring product quality. The overall structure is simple, the manufacturing cost is low, the attachment is convenient, and the operation is convenient for automated production.
