Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible circuit board production equipment, in particular to a FPC punching and taking device. BACKGROUND

[0002] FPC is a kind of printed circuit, also known as flexible circuit board, which is widely used in MP3, DVD, digital camera, mobile phone medical, automobile and aerospace fields due to its light weight, thin thickness and excellent characteristics such as free bending and folding.

[0003] At present, the FPC used for new energy power battery BMS management system is usually rectangular after production, so it is necessary to punch the long strip-shaped FPC to cut the rectangular FPC into multiple block structures with required shapes (such as rectangles), and the punching process of FPC will use a punching machine tool.

[0004] In the prior art, a FPC punching machine tool for removing static electricity is disclosed in Chinese Patent No. CN119502057A, which is used for punching FPC. After the FPC plate is fed, the punching block drives the punching die to move down to punch the FPC on the workbench, and the edge scrap on the FPC is cut off to punch the FPC into the required shape, and then the FPC after punching is discharged.

[0005] When discharging, the punching block moves down to drive the mounting plate to move down, so that the suction cup on the mounting plate moves down until the suction cup contacts the FPC after punching on the workbench. At this time, the air pump sucks the opening side of the suction cup to make the suction cup suck the FPC, and then the mounting plate drives the suction cup to move up to make the FPC separate from the workbench.

[0006] For the related technology in the above, since the movement track of the mounting plate is mainly linear, there is certain limitation, which leads to that the FPC is not flexible enough when discharging, so it needs to be improved. INVENTION CONTENTS

[0008] The FPC punching and taking device provided by the present application adopts the following technical scheme:

[0011] By adopting the above technical scheme, during production, the FPC plate to be processed is placed on the table top of the workbench, and then the punching mechanism is used to punch the FPC plate, so as to cut out a plurality of rectangular products.

[0012] Then the driving mechanism is used to control the workbench to move linearly on the base and away from the punching structure, the mechanical arm is used to control the fixing seat to move close to the workbench, so that each suction nozzle is above the workbench, the lifting member is used to control the fixing seat to move vertically downward, so that the suction nozzles contact the FPC, the vacuum generator is used to vacuumize the suction nozzles, and the suction nozzles are adsorbed to successfully adsorb the punched FPC.

[0013] Since the mechanical arm has multiple degrees of freedom, the mechanical arm is particularly flexible, can drive the suction nozzles to transfer the FPC to the support disc, and completes the placement of the product. In addition, after the punching of the FPC is completed, the suction nozzles can also be used to transfer the waste from the workbench, so that an additional waste unloading structure does not need to be additionally arranged.

[0014] Preferably, the driving mechanism is a ball screw pair or a linear motor.

[0019] By adopting the technical scheme, the outer ring of the ball bearing is connected with the fixed seat, and the threaded sleeve is installed on the inner ring, so that the threaded sleeve can rotate relative to the fixed seat. When the threaded sleeve is screwed on the piston rod, the fixed seat does not rotate.

[0044] The punching mechanism 4 is arranged on the base 1, is above the moving path of the workbench 2 and used for punching the FPC on the workbench 2, and the specific structure of the punching mechanism 4 belongs to the prior art and will not be described here. The manipulator 5 is arranged on one side of the workbench 2 and has multiple degrees of freedom, such as six degrees of freedom, so that the manipulator 5 has high flexibility. The lifting piece 6 is arranged on the manipulator 5, the fixing base 7 is movably arranged along the vertical direction and connected with the lifting piece 6, and the lifting piece 6 is used for controlling the up-down movement of the fixing base 7.

[0045] In the embodiment, the lifting piece 6 is a lifting cylinder, the lifting cylinder has a stroke control mechanism, and the fixing base 7 is detachably connected to the piston rod of the lifting cylinder. The stroke control mechanism can control the piston rod of the cylinder to stop at a predetermined position, realize accurate mechanical action (such as clamping, pushing, jacking, etc.), and can provide continuous, stable and reliable pressure. Typical stroke control mechanism types include but are not limited to mechanical stop block, magnetic switch plus solenoid valve, displacement sensor plus controller, which belong to the prior art means and will not be described here.

[0046] The suction nozzle 8 is arranged on the side of the fixing base 7 away from the lifting piece 6 and is spaced apart and distributed in several suction nozzles 8, each suction nozzle 8 is used for adsorbing the punched FPC on the workbench 2, the supporting disc 9 is arranged on one side of the workbench 2 and close to the manipulator 5, and the supporting disc 9 is used for placing the punched FPC.

[0047] During production, the FPC plate to be processed is placed on the table top of the workbench 2, then the FPC plate is punched by the punching mechanism 4, thereby cutting out several rectangular products. Then the workbench 2 is controlled to move linearly on the base 1 and away from the punching structure by the driving mechanism 3, the fixing base 7 is controlled to approach the workbench 2 by the manipulator 5, so that each suction nozzle 8 is above the workbench 2; then the fixing base 7 is controlled to move vertically downward by the lifting piece 6, so that the suction nozzle 8 contacts the FPC, the suction nozzle 8 is vacuumized by the vacuum generator, and the punched FPC is successfully adsorbed by the suction nozzle 8.

[0048] Due to the plurality of degrees of freedom of the mechanical arm 5, the suction nozzle 8 can be flexibly driven to transfer the FPC to the support disc 9 to complete the placement of the product. In addition, after the cutting of the FPC is completed, the suction nozzle 8 can be used to transfer the waste from the workbench 2, so that an additional waste cutting structure is not needed.

[0049] Specifically, the piston rod of the lifting cylinder is provided with external threads, the fixed seat 7 is fixed with a ball bearing 10 away from the suction nozzle 8, the outer ring of the ball bearing 10 is connected with the fixed seat 7, the inner ring of the ball bearing 10 is fixedly connected with a threaded sleeve 11, the threaded sleeve 11 is screwed on the piston rod, and the connection between the threaded sleeve 11 and the piston rod is realized by the screwing force. The existence of the ball bearing 10 can allow the threaded sleeve 11 and the fixed seat 7 to rotate relative to each other, and the fixed seat 7 will not rotate during the process of the worker screwing the threaded sleeve 11 on the piston rod. In some embodiments, the outer surface of the threaded sleeve 11 is provided with anti-skid lines. The anti-skid lines can improve the static friction force between the worker and the threaded sleeve 11, so that the threaded sleeve 11 can be better forced.

[0050] The side of the support disc 9 is further provided with a feeding disc 12, the plane of the feeding disc 12 is parallel to the plane of the support disc 9, and the feeding disc 12 is used for placing the FPC to be cut. The worker can place the FPC to be cut on the feeding disc 12, and then use the cooperation of the mechanical arm 5 and the suction nozzle 8 to transfer the FPC plate to the workbench 2 for cutting, and then transfer the finished product to the support disc 9 to complete the feeding and discharging operations.

[0051] In this embodiment, four parallel guide rails 13 are fixedly installed on the machine base 1 in the vertical direction, the support disc 9 is arranged on two adjacent guide rails 13 by sliding block lifting, the feeding disc 12 is also arranged on the other two adjacent guide rails 13 by sliding block lifting, the support disc 9 and the feeding disc 12 are moved up and down by the jacking cylinder 14, and the jacking cylinder 14 has a stroke control mechanism.

[0052] After the mechanical arm 5 and the suction nozzle 8 transfer the FPC plate to the workbench 2 for cutting, the mechanical arm 5 and the suction nozzle 8 can transfer the uppermost carrier plate of the feeding disc 12 to the support disc 9 by using the gap of the cutting, so as to facilitate the placement of the cut FPC. After such reciprocating operation, the carrier plates on the feeding disc 12 gradually decrease, and the overall height gradually decreases; the carrier plates on the support disc 9 are gradually stacked, and the overall height gradually increases, and there is a height difference between the two, which is not conducive to the operation of the mechanical arm 5 and the suction nozzle 8.

[0053] By setting two jacking cylinders 14 to control the height of the feeding disc 12 and the supporting disc 9 respectively, whenever the number of the carrier plates on the feeding disc 12 decreases, the feeding disc 12 is controlled to move vertically upward by a corresponding distance; whenever the number of the carrier plates on the supporting disc 9 increases, the supporting disc 9 is controlled to move vertically downward by a corresponding distance; so as to ensure that the upper end surface of the feeding disc 12 and the upper end surface of the supporting disc 9 are always flush, and realize the convenience of the manipulator 5 to carry out feeding and discharging operations.

[0054] In combination Figure 3 In addition, a waste box 15 is also placed on the ground, and the waste box 15 is provided with an opening for receiving the waste materials formed after the FPC is punched. After the suction nozzle 8 sucks up the waste materials, the manipulator 5 drives the suction nozzle 8 and the waste materials to rotate so that the waste materials are above the waste box 15. After the suction force of the suction nozzle 8 is removed, the waste materials fall into the waste box 15, so that subsequent workers can concentrate on pouring.

[0055] The implementation principle of the FPC punching and material taking device according to the embodiment of the application is as follows: in the production process, the FPC plate to be processed is placed on the table top of the workbench 2. Then, the punching mechanism 4 is used to punch the FPC plate, thereby cutting out a plurality of rectangular products.

[0056] Subsequently, the workbench 2 is controlled by the driving mechanism 3 to move linearly on the machine base 1 and move away from the punching mechanism. At the same time, the fixed seat 7 is controlled by the manipulator 5 to move close to the workbench 2 until each suction nozzle 8 is above the workbench 2. Then, the fixed seat 7 is driven by the lifting piece 6 to move vertically downward, so that the suction nozzle 8 contacts the FPC. At this time, the suction nozzle 8 is vacuumized by the vacuum generator, so as to ensure that the suction nozzle 8 can successfully adsorb the punched FPC.

[0057] Since the manipulator 5 has multiple degrees of freedom and high flexibility, it can drive the suction nozzle 8 to move the FPC to the supporting disc 9, thereby completing the product placement process. In addition, after the punched FPC is discharged, the suction nozzle 8 can also be used to transfer the waste materials from the workbench 2, so that it is not necessary to additionally add a waste discharging structure.

[0058] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
