Description

Technical Field

[0001] The utility model relates to the technical field of circuit board patch adhesive processing, in particular to a flexible printed circuit board patch adhesive cutting device. Background Art

[0002] FPCB is a flexible printed circuit board. In the production and processing of FPCB, a large amount of double-sided adhesive (chip adhesive) is used to stick and fix the chip. The shape of this double-sided adhesive generally depends on the shape of the electronic part to be stuck.

[0003] Therefore, it is necessary to cut the double-sided adhesive (patch adhesive), fix it with the help of a fixing component, and finally complete the cutting process with the help of a cutter component. Common cutting devices have the following technical problems: the equipment used to place and fix the patch adhesive is directly below the cutter component. When the patch adhesive is placed, fixed and removed directly below the cutter component, it is easy to touch the cutter component above, thereby injuring the operator. In addition, if the switch is accidentally touched during the operation to make the cutter drop, it will cause a serious accident to the operator below. In order to avoid the above situation, a patch adhesive cutting device for a flexible printed circuit board is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 The invention discloses a patch glue cutting device for a flexible printed circuit board, comprising a bottom frame 1, a vertical frame 2 is installed on the bottom frame 1, a horizontal screw 12 and a vertical screw 3 are respectively arranged in the bottom frame 1 and the vertical frame 2 through a driving motor, a nut 15 and a lifting rod 4 are respectively threadedly installed on the horizontal screw 12 and the vertical screw 3 through a limiting mechanism, a cutter 5 is installed on the lifting rod 4, connecting rods 7 are arranged on the outer walls on both sides of the cutter 5, a fixing frame 8 is arranged on the connecting rod 7 through a buffer mechanism, a connecting block 14 is arranged on the nut 15 through an insertion mechanism, a bottom plate 6 is installed on the connecting block 14, a cutting groove corresponding to the cutter 5 is arranged on the upper end surface of the bottom plate 6, and the bottom frame 1 and the bottom plate 6 are connected by an anti-slip mechanism.

[0022] The limiting mechanism includes limiting rods 13 arranged in the bottom frame 1 and the vertical frame 2. The two limiting rods 13 are respectively arranged horizontally and vertically. The two limiting rods 13 slide through the nut 15 and the lifting rod 4 respectively. The two limiting rods 13 are respectively arranged parallel to the vertical screw 3 and the horizontal screw 12. The two limiting rods 13 respectively limit the lifting rod 4 and the nut 15, thereby preventing the lifting rod 4 and the nut 15 from rotating together with the vertical screw 3 and the horizontal screw 12.

[0023] The buffer mechanism includes a movable rod 9 arranged on the fixed frame 8, and a movable groove corresponding to the movable rod 9 is provided at the end of the connecting rod 7. A spring 16 is elastically connected between the movable rod 9 and the inner wall of the movable groove. The spring 16 realizes the elastic buffering of the fixed frame 8. The fixed frame 8 is matched with the base plate 6 to realize the extrusion and fixation of the patch glue, while avoiding damage caused by excessive extrusion.

[0024] The plug-in mechanism includes an insert block arranged on the outer wall of the nut 15, an arc groove is provided on the surface corresponding to the nut 15 of the connecting block 14, and a slot corresponding to the insert block is provided on the inner wall of the arc groove. The insert block is welded and arranged on the outer wall of the nut 15, and the current status of the insert block and the slot are all drawn. It is a plug-in mechanism with a simple structure and will not be described in detail. Its function is: after the insert block is inserted into the slot, the nut 15 cooperates with the connecting block 14 to enable the base plate 6 to move synchronously.

[0025] The anti-slip mechanism includes an anti-slip rod 10 fixedly arranged on the outer wall of the bottom frame 1. The anti-slip rod 10 is U-shaped, and an anti-slip groove 11 corresponding to the anti-slip rod 10 is provided on the outer wall of the bottom plate 6. When the end of the anti-slip rod 10 is in the anti-slip groove 11, the bottom plate 6 cannot move vertically relative to the bottom frame 1, thereby playing the role of anti-slip and limiting.

[0026] The bottom wall of the fixing frame 8 and the upper end surface of the bottom plate 6 are both provided with protective pads made of rubber material. The rubber protective pads protect the patch adhesive to avoid damage caused by hard extrusion and have a certain buffering effect.

[0027] When the utility model is used, Figure 1 As shown, the patch glue is placed on the upper end surface of the bottom plate 6, and then the driving motor connected to the horizontal screw 12 is started, and the driving motor drives the horizontal screw 12 to rotate. When the horizontal screw 12 rotates, the nut 15 on its outer wall can cooperate with the plug block to drive the connecting block 14 to move, and the connecting block 14 drives the bottom plate 6 and the patch glue to move, and drives the patch glue to move to the bottom of the cutter 5, and then the driving motor connected to the vertical screw 3 is started, and the driving motor drives the vertical screw 3 to rotate. When the vertical screw 3 rotates, the lifting rod 4 on its outer wall drives the cutter 5 to descend, and the cutter 5 descends The cutting groove can realize the cutting operation of the patch adhesive. Before the cutter 5 contacts the patch adhesive for cutting, the fixing frame 8 contacts the patch adhesive before the cutter 5 to realize the downward pressing and fixing of the patch adhesive. The elastic potential energy provided by the spring 16 is used for buffering to ensure the stability of the patch adhesive when it is pressed down and fixed, while also avoiding damage caused by excessive squeezing. When the cutter 5 cuts and leaves the patch adhesive, the cutter 5 leaves the patch adhesive after the fixing frame 8, which can effectively avoid the patch adhesive cutting point from adhering to the outer wall of the cutter 5, thereby preventing the patch adhesive from being driven by the rise of the cutter 5.

[0028] In this solution, the patch adhesive can be taken and placed only after the bottom plate 6 moves away from the cutter 5 and is offset from the cutter 5, so as to avoid collision with the cutter 5 during the taking and placing process, thereby preventing the operator from being injured.

[0029] In this solution, when the bottom plate 6 continues to move away from the vertical frame 2 driven by the horizontal screw 12, the anti-slip rod 10 will eventually disengage from the anti-slip groove 11, and the vertical limit of the bottom plate 6 will be released. The bottom plate 6 can be lifted up to disengage the connecting block 14 and other components from the horizontal screw 12 and other components. After the bottom plate 6 is conveniently disassembled and cleaned, it is more convenient to pour out and clean the waste in the cutting groove.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
