Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and more particularly, to a transfer device manufactured based on a circuit board. Background Art

[0002] Circuit board is an important material used to support and connect electronic components. It is usually made of insulating material and covered with conductive metal lines on the surface to achieve circuit connection. Circuit boards are widely used in various electronic products, such as computers, mobile phones, home appliances, automobiles and medical equipment. According to the complexity, circuit boards can be divided into different types such as single-sided boards, double-sided boards and multi-layer boards. In the production process of circuit boards, it is often necessary to use a transfer device to move copper clad laminates for different types of processing. Copper clad laminates are key materials in the manufacturing process of circuit boards, and their quality directly affects the performance of circuit boards, including conductivity, insulation and heat resistance.

[0003] At present, electrostatic adsorption often occurs during the transportation of copper clad laminates, which makes it easy for copper clad laminates to adsorb to each other. When the robot arm is driven to perform a clamping operation, the copper clad laminate on the lower layer may be adsorbed on the copper clad laminate on the upper layer, forming an overlapping state. This overlapping state not only affects subsequent processing, but may also cause errors during the processing. When copper clad laminates overlap, defects may occur in the produced products, reducing the yield rate in the circuit board manufacturing process and increasing production costs. Summary of the invention

[0004] The present invention provides a transfer device based on circuit board manufacturing, which solves the technical problem in the related art that the copper clad laminate of the lower layer may be adsorbed on the copper clad laminate of the upper layer, thereby forming a superimposed state. When the copper clad laminates overlap, defects may be caused in the produced products, which reduces the yield rate in the circuit board manufacturing process and increases the production cost.

[0011] As a further optimization scheme of the present invention, the centers of the cam and the connecting shaft are not on the same central axis, and the cam is biased on the connecting shaft.

DETAILED DESCRIPTION

[0027] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0028] according to Figure 1 As shown, a transfer device based on circuit board manufacturing includes a copper clad laminate feeder 100, a transfer robot arm 200, a suction cup clamp 300 and a conveyor 400, which are used to transfer and convey the copper clad laminate, the main material for circuit board manufacturing. Among them, the copper clad laminate is a material commonly used in the electronics industry, mainly used in the manufacture of printed circuit boards. It is usually composed of an insulating substrate and a copper foil layer. The main function of the copper clad laminate is to provide electrical connections and support components. When producing circuit boards, the copper clad laminate is taken out of the copper clad laminate feeder 100 by driving the transfer robot arm 200 using the suction cup clamp 300, and the copper clad laminate is placed in the conveyor 400 for transportation using the suction cup clamp 300.

[0029] Specifically, the copper clad laminate feeder 100 includes a body 101 and an inner lining board 102 installed in the body 101, and an interlayer space is formed between the body 101 and the inner lining board 102. Figure 1 , Figure 2 and Figure 3 As shown, the suction cup clamp 300 is disposed on the transfer robot arm 200. When the transfer robot arm 200 is driven to perform mechanical movement according to a set path, the suction cup clamp 300 moves synchronously.

[0030] according to Figures 2 to 5 As shown, the suction cup clamp 300 includes a connecting frame 301 installed on the transfer robot arm 200, and a first airflow connecting tube 302 is symmetrically installed on the connecting frame 301, and a second airflow connecting tube 303 is also provided on the side away from the first airflow connecting tube 302, and multiple sleeves 304 are installed on the first airflow connecting tube 302 and the second airflow connecting tube 303, and flexible suction cups 305 are installed on the sleeves 304, and the sleeves 304 are respectively connected to the interior of the first airflow connecting tube 302 and the second airflow connecting tube 303, so as to control the suction and discharge of the airflow inside the flexible suction cup 305, so as to facilitate the grasping and release of the copper clad laminate.

[0031] In this embodiment, air ports are installed on the first airflow connecting tube 302 and the second airflow connecting tube 303, and the air ports are connected to the air pump through an external hose. When the air pump is controlled to suck air, the air in the first airflow connecting tube 302 and the second airflow connecting tube 303 is evacuated, so that a vacuum is formed inside the flexible suction cup 305, thereby adsorbing and clamping the copper clad laminate, which is convenient for the transfer operation of the copper clad laminate.

[0032] In addition, according to Figure 6 As shown, a movable rod 306 is installed on the second air flow connecting tube 303, and the movable rod 306 is slidably connected to the inside of the connecting frame 301, and a bracket 307 is installed at a position corresponding to the movable rod 306 on the connecting frame 301, and a swing arm 308 is rotatably connected to the bracket 307 through a rotating shaft, a limiting groove 309 is provided inside the swing arm 308, and a limiting rod 310 is slidably connected in the limiting groove 309, and is slidably connected to the limiting rod 310 through the limiting groove 309, which is used to provide a clearance space between the movable rod 306 and the swing arm 308, so that when the swing arm 308 is pressed down, the movable rod 306 can be lifted upward, thereby driving the second air flow connecting tube 303 to move synchronously, so that the flexible suction cups 305 on the left and right sides move upward, so as to facilitate the slight upward bending of the two sides of the copper clad board, which is used to separate the copper clad boards adsorbed together and remove the excess copper clad boards, and the limiting rod 310 is fixedly connected to the movable rod 306.

[0033] Furthermore, an annular protrusion 311 is installed on the movable rod 306, and the annular protrusion 311 is located on the upper surface of the connecting frame 301. The annular protrusion 311 is used to limit the movable rod 306 so that the movable rod 306 cannot move downward. When the swing arm 308 is driven upward to move, the movable rod 306 is limited by the setting of the annular protrusion 311, so that the movable rod 306 remains stationary.

[0034] It should be supplemented that a first spring 312 is provided on the movable rod 306, and the first spring 312 is used to elastically connect the connecting frame 301 and the second airflow connecting tube 303 to maintain the distance between the connecting frame 301 and the second airflow connecting tube 303, so that the first airflow connecting tube 302 and the second airflow connecting tube 303 are located on the same horizontal line in the default state, which is convenient for the transfer operation of the copper clad laminate. One end of the first spring 312 is installed on the connecting frame 301, and the other end of the first spring 312 is installed on the second airflow connecting tube 303.

[0035] according to Figure 5 and Figure 7 As shown, claws 313 are symmetrically arranged inside the body 101, and the claws 313 are located in the interlayer space formed between the body 101 and the inner lining plate 102, a shaft rod 314 is installed on the claw 313, and the shaft rod 314 and the lining plate are rotatably connected through a bearing, a torsion spring 315 is provided on the shaft rod 314, and one end of the torsion spring 315 is installed on the claw 313, and the other end of the torsion spring 315 is installed on the lining plate, and a clamping plate 316 is also provided on the claw 313 for limiting the movement of the claw 313, and the clamping plate 316 is fixedly connected to the lining plate.

[0036] It should be understood that when the swing arm 308 is driven to move downward so that the swing arm 308 contacts the claw 313, the movable rod 306 is limited by the annular protrusion 311, and the swing arm 308 remains stationary, so that the swing arm 308 squeezes the claw 313. When the swing arm 308 squeezes the claw 313, the claw 313 rotates around the shaft 314, so that the swing arm 308 can pass over the claw 313, so that the flexible suction cup 305 remains on a horizontal plane, which is convenient for vacuum adsorption of the copper clad laminate and transportation of the copper clad laminate.

[0037] Among them, according to Figure 7 As shown, an inclined slot 317 is provided on the lower surface of the claw 313. When the transfer robot arm 200 drives the suction cup clamp 300 to move upward to transfer the copper clad laminate to the conveyor 400, during the upward movement of the suction cup clamp 300, the swing arm 308 contacts the claw 313, and the claw 313 is limited by the clamping plate 316, so that the swing arm 308 rotates when passing through the claw 313, and the swing arm 308 is squeezed by the inclined slot 317, and the end of the swing arm 308 away from the movable rod 306 is squeezed downward, driving the movable rod 306 to move upward, so that the flexible suction cups 305 on the left and right sides can move upward synchronously, and the two sides of the copper clad laminate are slightly bent upward, so as to facilitate the separation of the copper clad laminates that are stacked or adsorbed together.

[0038] Specifically, a roller 318 is connected to the bearing at one end of the claw 313 that is close to the claw 313. When the claw 313 squeezes one end of the swing arm 308 and rotates downward, the swing arm 308 pushes the movable rod 306 upward, and the copper clad plates that are stacked or adsorbed together are separated. Through the setting of the roller 318, when the swing arm 308 passes the end of the side close to the claw 313, the roller 318 can increase the stability of the swing arm 308 moving out of the claw 313, thereby avoiding jamming and affecting the processing efficiency.

[0039] according to Figures 1 to 7 As shown, in summary, when producing circuit boards, the transfer robot arm 200 is driven to move to the inside of the copper clad laminate loading machine 100, and the copper clad laminate is sucked and grasped by the suction cup clamp 300; and when the suction cup clamp 300 is working, the flexible suction cup 305 sucks and clamps the copper clad laminate, and in the process of the transfer robot arm 200 moving upward, the swing arm 308 contacts the claw 313, squeezing the claw 313 upward, so that the clamping plate 316 limits the claw 313.

[0040] Secondly, as the transfer robot arm 200 continues to move upward, the end of the swing arm 308 that contacts the claw 313 rotates downward around the rotating shaft, thereby driving the movable rod 306 to move upward. At the same time, the second air flow connecting tubes 303 on both sides move upward synchronously, so that the flexible suction cups 305 on the left and right sides drive the two ends of the copper clad laminate to slightly tilt upward, separating the copper clad laminates that are adsorbed together, avoiding overlapping of the copper clad laminates during the loading process, and improving the stability of the circuit board processing production line.

[0041] In addition, when the transfer robot arm 200 drives the swing arm 308 to move upward continuously, when the swing arm 308 and the claw 313 are released from the limit, the second airflow connecting tube 303 is reset under the action of the elastic restoring force of the first spring 312, so that the flexible suction cup 305 is restored to the same horizontal plane, which facilitates the transfer of the copper clad laminate to the conveyor 400 and transporting it to the next process for processing.

[0042] according to Figure 8 , Fig. 9 and Fig.10As shown, a positioning and correction mechanism 500 is provided inside the inner lining plate 102, and the positioning and correction mechanism 500 includes a positioning plate 501 symmetrically arranged inside the inner lining plate 102, and a connecting shaft 502 connected to the upper and lower sides of the inner interlayer space by bearings, a cam 503 is installed on the connecting shaft 502, and the cam 503 is used to push the positioning plate 501 outward, so as to position and correct the copper clad laminate, and the connecting shafts 502 are connected by a pulley transmission mechanism 504. Among them, the center of the cam 503 and the connecting shaft 502 are not on the same central axis, and the cam 503 is eccentrically arranged on the connecting shaft 502. When the connecting shaft 502 rotates, the cam 503 rotates eccentrically, so that the cam 503 can push the positioning plate 501 out, so that the positioning plate 501 contacts the outer wall of the copper clad laminate, and the copper clad laminate is limited and fixed.

[0043] Furthermore, a gear 505 is installed on one set of connecting shafts 502, and a rack plate 506 is installed on the side away from the second airflow connecting tube 303. When the rack plate 506 moves toward the position of the gear 505, the gear 505 is meshed and connected with the rack plate 506, so that the connecting shaft 502 rotates, thereby driving the cam 503 to rotate, so that the positioning plate 501 contacts the outer wall of the copper clad laminate, thereby limiting and fixing the copper clad laminate.

[0044] It should be noted that a plurality of guide rods 507 are also installed on the positioning plate 501, and the guide rods 507 are slidably connected to the inner lining plate 102. A second spring 508 is also provided on the guide rod 507, and one end of the second spring 508 is fixedly connected to the guide rod 507, and the other end of the second spring 508 is fixedly connected to the inner lining plate 102. In this embodiment, by setting the guide rod 507 and the second spring 508, when the cam 503 squeezes the positioning plate 501, the second spring 508 generates elastic deformation and has a restoring force, so that when the squeezing between the cam 503 and the positioning plate 501 is released, the auxiliary positioning plate 501 is reset to facilitate the positioning of the copper clad laminate next time. At the same time, the reset of the copper clad laminate can leave a space for the suction cup clamp 300 to clamp the copper clad laminate, so as to facilitate the grabbing and transportation of the copper clad laminate.

[0045] according to Figure 5 and Figure 8As shown, a guide cover 600 is installed on the machine body 101, and the guide cover 600 is connected with the machine body 101 and the inner lining plate 102. An air supply pipe is also installed on the guide cover 600, and the air supply pipe is connected to the air supply device through an external hose. The air supply device can be a mechanical component such as an air pump. An air flow opening 509 is opened on the positioning plate 501, and the air flow opening 509 corresponds to the position of the guide cover 600. When separating the copper clad laminate, air is supplied into the guide cover 600 through the air supply device, so that the guide cover 600 blows the gas to the air flow opening 509, and passes through the air flow opening 509 to contact the copper clad laminate, and blows the side of the copper clad laminate adsorbed by the adsorption superposition, thereby improving the separation efficiency.

[0046] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
