Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, specifically an adsorption-type extraction device for circuit board flipping. Background Technology

[0002] Circuit boards are important electronic components, serving as the support for electronic components and the carrier for their electrical interconnection. They are generally made of insulating, heat-resistant, and non-bending materials, such as fiberglass and ceramics. The surface of the substrate is usually covered with a thin copper foil, typically only tens to hundreds of micrometers thick. This copper foil is used to create circuit traces. Various conductive lines are formed on the copper foil through etching processes. These lines, like roads in a city, are used to connect various electronic components, enabling them to function according to their designed circuit functions.

[0003] Circuit board flipping is a common operation in circuit board manufacturing, assembly, and repair. Flipping methods include manual flipping, flipping with simple tools, and automated equipment flipping, all to facilitate circuit board production. Chinese Patent Application No. 202420819172.0 discloses a circuit board processing flipping machine, including a brake motor. The output shaft of the brake motor is fixedly connected to a fixed shaft, and drive components are sleeved on both the front and back sides of the fixed shaft. With a first flipping assembly and a second flipping assembly, driven by the drive components, the first flipping assembly picks up a circuit board from the conveyor belt and flips it onto the second flipping assembly. The second flipping assembly then resets and places the circuit board back on. The height difference between the first and second flipping assemblies is small when exchanging and flipping circuit boards, and the circuit board slides stably with the support of the first and second support blocks, ensuring the integrity of the circuit board's shape and avoiding damage caused by flipping during processing. Furthermore, under the illumination of the first and second light boards, the circuit board can be flipped again after processing. During the flipping process, it assists workers in visually inspecting the circuit board.

[0004] However, the above-mentioned circuit board processing flipping machine has the following problems in actual use: the circuit board needs to slide during the flipping process, which can easily lead to scratches on the circuit board and affect its quality.

[0005] Therefore, an adsorption-type extraction device for circuit board flipping is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an adsorption-type extraction device for flipping circuit boards. It has the advantage of using a vacuum suction cup to adsorb and flip the circuit board, which, compared with the traditional mechanical clamping method, does not leave clamp marks on the surface of the circuit board or cause mechanical damage such as squeezing deformation to the edge of the circuit board.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adsorption-type extraction device for flipping circuit boards, comprising a frame, on which a first conveying platform and a second conveying platform are installed, and an adsorption flipping component is provided between the first conveying platform and the second conveying platform;

[0008] The adsorption and flipping assembly includes a central shaft, a flipping rod fixedly connected to the central shaft, a vacuum suction cup mounted on the flipping rod, a vacuum generating device connected to the vacuum suction cup through a vacuum tube assembly, a driven gear connected to one end of the central shaft, a driving gear meshing with the driven gear, and a drive motor connected to the driving gear through a motor shaft.

[0011] Preferably, the second conveying platform includes two sets of symmetrically arranged driving wheels and driven wheels, a second conveyor belt connecting the driving wheels and driven wheels, a connecting rod fixedly connected between the driving wheels, and one of the driving wheels is connected to a second motor through a motor shaft.

[0012] Preferably, the distance between the two second conveyor belts is greater than the distance between the two tilting rods, and the tilting rods can rotate to a position between the two second conveyor belts.

[0013] Preferably, the vacuum tube assembly includes a connecting tube for connecting to a vacuum suction cup, the connecting tube passing through a flip rod and connected to a connecting tube, the connecting tubes being connected to each other by a horizontal tube, the horizontal tube being connected to a bend, the end of the bend being fitted with a pipe joint, and the pipe joint being connected to a flexible hose.

[0014] Preferably, two mounting plates are fixedly connected to the top of the frame at a position corresponding to the central shaft, and the end of the central shaft away from the driven gear is connected to the corresponding mounting plate through a bearing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a vacuum adsorption method to move the circuit board by setting up an adsorption flipping component. Compared with the traditional mechanical clamping method, it will not leave clamping marks on the surface of the circuit board or cause mechanical damage such as squeezing and deformation of the edge of the circuit board. Especially for some circuit boards with precision lines or sensitive components on the surface, this gentle adsorption method can effectively protect their integrity and reduce the scrap rate.

[0017] 2. This utility model sets up a first conveying platform and a second conveying platform to input and output the circuit board flipping operation, ensuring the continuity of the flipping operation and improving production efficiency. In addition, the second conveying platform can effectively cooperate with the adsorption flipping component to facilitate the flipping operation. Attached Figure Description

[0033] The adsorption and flipping assembly 4 includes a central shaft 401, a flipping rod 402 fixedly connected to the central shaft 401, a vacuum suction cup 403 mounted on the flipping rod 402, a vacuum generator 405 connected to the vacuum suction cup 403 via a vacuum tube assembly 404, a driven gear 406 connected to one end of the central shaft 401, a driving gear 407 meshing with the driven gear 406, and a drive motor 408 connected to the driving gear 407 via a motor shaft. The circuit board is moved using vacuum adsorption, which, compared to traditional mechanical clamping methods, avoids leaving clamp marks on the circuit board surface or causing mechanical damage such as squeezing deformation to the edges of the circuit board. Especially for circuit boards with precision lines or sensitive components on their surface, this gentle adsorption method effectively protects their integrity and reduces the scrap rate.

[0034] Specifically, the frame 1 includes two symmetrically arranged fixing plates 101. Multiple corresponding support legs 102 are fixedly connected to the bottom of the fixing plates 101, and reinforcing rods 103 are fixedly connected between adjacent support legs 102.

[0035] Furthermore, the first conveying platform 2 includes a driving roller 201 and a driven roller 202 arranged on the left and right respectively, and a first conveyor belt 203 is connected between the driving roller 201 and the driven roller 202. One end of the driving roller 201 is connected to a first motor 204 through a motor shaft.

[0036] Furthermore, the second conveying platform 3 includes two sets of symmetrically arranged drive wheels 301 and driven wheels 302. A second conveyor belt 303 is connected between the drive wheels 301 and driven wheels 302. A connecting rod 304 is fixedly connected between the drive wheels 301. One of the drive wheels 301 is connected to a second motor 305 through a motor shaft.

[0037] It is worth noting that the distance between the two second conveyor belts 303 is greater than the distance between the two tilting rods 402, and the tilting rods 402 can rotate to the position between the two second conveyor belts 303.

[0038] It is worth noting that the vacuum tube assembly 404 includes a connecting tube 4041 that connects to the vacuum suction cup 403.

At the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.

[0041] Working principle and process: The circuit board is placed on the first conveyor belt 203 of the first conveying platform 2. The first motor 204 is started, which in turn drives the first conveyor belt 203 and the driven roller 202 to rotate, thus conveying the circuit board to the position corresponding to the vacuum suction cup 403. The second motor 305 is started, which in turn drives the driven gear 406 to rotate, and the central shaft 401 drives the flipping rod 402 to rotate, so that the vacuum suction cup 403 is attached to the upper surface of the circuit board. The vacuum generator 405 is started, which allows the vacuum suction cup 403 to adsorb the circuit board. Then, the drive motor 408 is started to rotate in the opposite direction, which flips the circuit board onto the second conveyor belt 303 of the second conveying platform 3. The second motor 305 is started, which in turn drives the second conveyor belt 303 and the driven wheel 302 to rotate, thus outputting the circuit board. After the circuit board has moved, the second motor 305 of the adsorption and flipping assembly 4 is started again to reset the vacuum suction cup 403 to adsorb the next circuit board.
