Description

Technical Field

[0001] This utility model relates to the technical field of printed circuit board processing equipment, specifically to a flipping mechanism, and particularly to a flipping mechanism for a sun-type flipping machine. Background Technology

[0002] Printed circuit boards (PCBs) undergo multiple processing steps, and cooling is often required when transferring them from one step to another. During production, stacking PCBs together hinders heat dissipation and slows down the cooling process. Traditional PCB cooling methods involve manually separating the PCBs for cooling, a process that requires significant manpower, storage space, and time.

[0003] Therefore, the purpose of this utility model is to provide a flip-plate mechanism to solve the above-mentioned technical problems. Summary of the Invention

[0006] Furthermore, the driving device is a servo motor.

[0007] Furthermore, the driving device includes a drive motor and a cam divider connected to the output shaft of the drive motor, wherein the output shaft of the cam divider is connected to the flip plate rotating shaft.

[0008] Furthermore, the distance between two adjacent turntables is less than 100mm.

[0009] Furthermore, the included angle between two adjacent support rods on the same turntable is 5-10°.

[0010] Furthermore, the support rod is circular.

[0011] Furthermore, the circuit board supported by the support rod has a maximum size of 730*630mm and a minimum size of 300*300mm.

[0012] Compared with the prior art, the flip-plate mechanism provided by this utility model has the following advantages: I. The flipping mechanism provided by this utility model has multiple support rods arranged in a ring array on its turntable. When the circuit board is conveyed to the flipping mechanism by the conveying mechanism, the circuit board is supported on the support rods. During the rotation of the flipping mechanism, the circuit board is cooled. Since the flipping mechanism can continuously cool multiple circuit boards, it saves storage space, improves cooling efficiency, and saves manpower.

[0013] II. The flip-plate mechanism provided by this utility model includes a support rod for supporting the circuit board, comprising a glass fiber rod and a Teflon sleeve sleeved on the surface of the glass fiber rod. The glass fiber rod provides support strength. By sleeved with a Teflon sleeve, it can effectively prevent short circuits, leakage and other problems caused by static electricity or electromagnetic interference during the transportation of the circuit board, and ensure the safe operation of electronic components.

[0014] Third, the flipping mechanism provided by this utility model includes a cam divider as the driving device, which is used to precisely control the interval time of the turntable's intermittent movement, prevent the circuit board from shaking during the flipping process, and improve the stability of the flipping mechanism's operation.

[0018] To enable those skilled in the art to better understand the technical solutions in the embodiments of this utility model, and to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be further described below in conjunction with the accompanying drawings.

[0019] It should be noted that the descriptions of these embodiments are for the purpose of aiding understanding of the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] The flipping mechanism of this utility model is a component of a sun-type flipping machine. The following detailed description of the overall mechanism of the sun-type flipping machine illustrates the structure and working principle of the flipping mechanism.

[0021] Please refer to the following: Figures 1 to 3 ,in Figure 1 This is a structural schematic diagram of the sun-type flipping machine in this utility model. Figure 2 yes Figure 1 A schematic diagram of the sun-type flip-plate machine from another angle; Figure 3 yes Figure 1 The diagram shows a structural schematic of the sun-type flipping machine from another angle. The sun-type flipping machine of this utility model includes a frame 1, a circuit board flipping mechanism 2 mounted on the frame 1, a circuit board conveying mechanism 3 mounted on the frame and located on both sides of the circuit board flipping mechanism, and an anti-jamming device (not labeled).

[0022] The circuit board flipping mechanism 2 includes a drive device 21, a flipping shaft 23 connected to the drive device, a plurality of turntables 24 disposed on the flipping shaft and spaced apart, and a plurality of support rods 25 arranged in a ring array on each turntable.

[0023] In this embodiment, the driving device 21 includes a drive motor 211 and a cam divider 212 connected to the output shaft of the drive motor. The output shaft of the cam divider 212 is connected to the flip plate rotating shaft. The cam divider 212 can accurately control the interval time of the turntable's intermittent movement, improve the stability of the flip plate mechanism, and prevent the circuit board from shaking during the flipping process.

[0024] In addition to the above-mentioned technical solutions, the drive device can also be a servo motor, which can also be used to control the intermittent frequency of rotation.

[0025] In this embodiment, there are six turntables 24, each connected to the flip plate shaft via bearings. Each turntable 24 has several insertion holes on its outer circumference, and a support rod 25 is inserted into each hole. The number of insertion holes on each turntable 24 is the same; that is, after inserting the support rods, the support rods at the same position on the six turntables are on the same plane, which can be used to support the circuit board. In this embodiment, the maximum size of the circuit board supported by the support rod is 730*630mm, and the minimum size is 300*300mm.

[0026] Figure 4 yes Figure 2 The diagram shows an enlarged view of part A. In this embodiment, the support rod 25 includes a fiberglass rod 251 and a Teflon sleeve 252 fitted over the surface of the fiberglass rod 251. The fiberglass rod 251 enhances the support strength of the support rod. By fitting the Teflon sleeve over the rod, short circuits and leakage caused by static electricity or electromagnetic interference during the circuit board's transport process can be effectively prevented, ensuring the safe operation of electronic components. In this embodiment, the support rod 25 is circular or square.

[0027] In this invention, the included angle between two adjacent support rods on the same turntable is 5-10°, which can prevent the circuit board from shaking when supporting it; the distance between the support rods on two adjacent turntables is less than 100mm, which makes the circuit board support more stable.

[0028] The conveying mechanism 3 includes a first conveying mechanism 31 located at the inlet end of the flipping mechanism 2 and a second conveying mechanism 32 located at the outlet end of the flipping mechanism 2. The first conveying mechanism 31 and the second conveying mechanism 32 have the same structure, and only the structure of the first conveying mechanism is described in detail below.

[0029] The first conveying mechanism 31 includes a drive shaft 311, a plurality of drive wheels 312 disposed on the drive shaft 311 and spaced apart, driven wheels 313 corresponding to each drive wheel, and a plurality of conveyor belts 314 disposed around the drive wheels 312 and driven wheels 313 and spaced apart. A belt support plate 315 is disposed between the drive wheels and the driven wheels, with one end connected to the frame and the other end connected to and fixed to the driven wheel.

[0030] In this embodiment, the number of conveyor belts surrounding the drive wheel and driven wheel is the same as the number of drive wheels. During operation, the support rods of different turntables are distributed between adjacent conveyor belts at corresponding positions. In this embodiment, the number of conveyor belts corresponds to the number of support rods.

[0031] In this embodiment, the conveying speed of the first conveying mechanism and the second conveying mechanism is 3-15m / min, which is adapted to the flipping speed of the flipping mechanism to ensure the cooling effect of the circuit board.

[0032] In this embodiment, the surface of the belt support plate has a wear-resistant material layer, which increases the wear resistance of the belt support plate and prevents the belt from rubbing against it and shedding debris. On the one hand, this reduces the impact of debris on the quality of the circuit board, and on the other hand, it increases the service life of the belt. Preferably, the wear-resistant material layer is a wear-resistant stainless steel liner.

[0033] The anti-jamming device includes a sensor 41 for detecting changes in the force on the conveyor belt, a controller 42, and an alarm 43. The sensor 41 and alarm 43 are electrically connected to the controller 42. The sensor sends a detection signal to the controller. When the sensor detects a change in the force on the conveyor belt exceeding a set value, it indicates that the number of circuit boards carried on the conveyor belt exceeds the set value, resulting in board stacking or jamming. At this time, the controller activates the alarm, and personnel handle the jamming problem. In this embodiment, the sensor 41 is mounted on the belt support plate of the first conveyor mechanism 31, and is preferably a tension sensor.

[0034] The working principle of this solar-type flipping machine is as follows: The circuit board is conveyed to the first conveyor mechanism and then forward under the action of the conveyor belt; The turntable of the flipping mechanism rotates, and one set of support rods rotates to the bottom of the conveyor belt. Under the intermittent operation of the drive device, the turntable stops rotating. At this time, the circuit board is conveyed to the top of the support rods located below the conveyor belt. Under the action of the drive device, the turntable rotates, which drives the circuit board located on the support rods to rotate together. This cycle is repeated so that the circuit board is clamped between the support rods that are distributed in a ring on the turntable, and the circuit board is cooled during the rotation of the turntable. When the circuit board is driven by the turntable to the second conveyor mechanism (rotating 180°), the support rod rotates to the bottom of the conveyor belt of the second conveyor mechanism. At this time, the circuit board is supported on the conveyor belt and completes the discharge under the action of the conveyor belt.

[0035] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
