Description
Technical Field
[0001] This utility model belongs to the field of mounting equipment technology, and in particular relates to a vibratory feeder and a material transfer mechanism. Background Technology
[0002] Flexible circuit boards (PCBs) are circuit boards made of flexible insulating substrates. They possess properties such as free bending, winding, and folding, and can be arranged arbitrarily according to spatial layout requirements. Using flexible circuit boards can significantly reduce the size of electronic products, meeting the development needs of electronic product lines towards high density, miniaturization, and high reliability. During the production process of flexible circuit boards, reinforcing sheets need to be attached to their surface. These reinforcing sheets increase the mechanical strength of the flexible circuit board, thereby facilitating the assembly of components on its surface.
[0003] With the continuous advancement of automation technology, more and more manufacturers are using automatic placement machines to assemble components on flexible circuit boards. Automatic placement machines include vibratory feeders and transfer / adsorption robots. The vibratory feeder can automatically flip the components, while the transfer / adsorption robot can pick up the components from the vibratory feeder and place them onto the flexible circuit board. Although existing vibratory feeders can flip the components, the components often have a lot of dust on them, which affects the stability of the components when transferred to the flexible circuit board. Summary of the Invention

[0026] like Figure 1 As shown, one embodiment of the present invention provides a vibratory feeder, including a material storage component 1, a dust screening component 2, and a material turning component 3; it can be understood that the dust screening component 2 is located between the material storage component 1 and the material turning component 3, so that the components on the material storage component 1 can be transported to the material turning component 3 through the dust screening component 2.
[0027] The dust screening assembly 2 includes a vibration drive 21, a dust collection box 22, and a dust screening disc 23 with screen holes 231. The dust screening disc 23 is used to receive components (not shown in the figure) conveyed by the material storage assembly 1. The vibration drive 21 is connected to the dust screening disc 23 and is used to drive the dust screening disc 23 to vibrate. The dust collection box 22 is used to receive dust falling through the screen holes 231. Understandably, the dust screening disc 23 is installed above the vibration drive 21, and the dust collection box 22 is located directly below the screen holes 231. The components include, but are not limited to, capacitors, inductors, reinforcing sheets, etc.
[0028] The material turning assembly 3 includes a material turning disc 31 connected to the dust screening disc 23; the material turning disc 31 is used to receive the components conveyed by the dust screening disc 23 and drive the components on it to turn over. It can be understood that the vibration drive 21 can drive the dust screening disc 23 and the material turning disc 31 to vibrate synchronously.
[0029] In this invention, the dust screening assembly 2 includes a vibration drive 21, a dust storage box 22, and a dust screening disc 23 with screen holes 231. The dust screening disc 23 is used to receive components conveyed by the storage assembly 1. The vibration drive 21 is connected to the dust screening disc 23, and the dust storage box 22 is located directly below the screen holes 231. The material turning assembly 3 includes a turning disc 31 connected to the dust screening disc 23. The storage assembly 1 conveys components onto the dust screening disc 23, and the vibration drive 21 drives the dust screening disc 23. Vibration occurs when components vibrate on the dust collection tray 23, causing dust and impurities to fall through the sieve holes 231 into the dust collection box 22, ensuring the cleanliness of the components on the dust collection tray 23. The dust collection tray 23 can then transport the components to the turning tray 31. The vibration drive 21 can also drive the turning tray 31 to vibrate, causing the components on it to turn over. An external robotic arm can then pick up the components from the turning tray 31 and assemble them onto a circuit board. This vibratory feeder not only completes the component turning process but also ensures the cleanliness of the components; furthermore, the vibratory feeder has a simple structure, low manufacturing cost, and small footprint.
[0030] In one embodiment, such as Figure 1 As shown, the vibratory feeder also includes a blocking assembly 4, which includes a lifting drive 41 and a blocking member 42 surrounding the tilting tray 31. The lifting drive 41 is connected to the blocking member 42 and is used to drive the blocking member 42 to move up and down. It is understood that the lifting drive 41 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc., and the blocking member 42 can surround the tilting tray 31. Specifically, when the lifting drive 41 drives the blocking member 42 to rise, the blocking member 42 is located above the tilting tray 31, thus preventing components on the tilting tray 31 from splashing and falling; when the lifting drive 41 drives the blocking member 42 to fall, the blocking member 42 is located below the tilting tray 31, thus preventing interference between the external robotic arm removing components from the tilting tray 31 and the blocking member 42.
[0031] In one embodiment, such as Figure 1 As shown, the blocking member 42 includes a frame 421 surrounding the tilting tray 31 and a brush 422 mounted on the frame 421. The output end of the lifting drive member 41 is connected to the frame 421. Understandably, the brush 422 is mounted on the top surface of the frame 421. The brush 422 is a flexible component, and it can prevent damage to components, thus ensuring the quality of the components.
[0032] In one embodiment, such as Figure 1As shown, the storage assembly 1 includes a storage funnel 11 and a buffer tray 12 connected to the storage funnel 11. The buffer tray 12 is used to receive components in the storage funnel 11. Understandably, the storage funnel 11 is installed above the buffer tray 12. The storage funnel 11 can store a large number of components, and the components in the storage funnel 11 can automatically fall onto the buffer tray 12.
[0033] The buffer tray 12 is provided with a discharge port, through which the components in the buffer tray 12 are conveyed to the dust screening tray 23. It can be understood that the components on the buffer tray 12 can be conveyed to the dust screening tray 23 through the discharge port. In this embodiment, the buffer tray 12 can buffer the components, ensuring the smoothness of the material storage assembly 1 conveying the components to the dust screening tray 23.
[0034] In one embodiment, such as Figure 1 As shown, the storage assembly 1 also includes a baffle 13, which is mounted on the buffer plate 12 and used to adjust the opening degree of the discharge port. Understandably, the baffle 13 adjusts the opening degree of the discharge port, thereby allowing the vibratory feeder to transport components of different sizes, improving the applicability and versatility of the vibratory feeder.
[0035] In one embodiment, such as Figure 1 As shown, the buffer disk 12 and the dust screening disk 23 are integrally formed. Understandably, the opposite ends of the dust screening disk 23 are connected to the buffer disk 12 and the turning disk 31, respectively. The vibration drive 21 can simultaneously drive the buffer disk 12, the dust screening disk 23, and the turning disk 31 to vibrate synchronously, thereby allowing components on the buffer disk 12 to be transported to the dust screening disk 23, the dust screening disk 23 to transport its components to the turning disk 31, and the turning disk 31 to flip its components. In this embodiment, the buffer disk 12, the dust screening disk 23, and the turning disk 31 share a single vibration drive 21, resulting in a simple structure and low manufacturing cost for this vibratory disk.
[0036] In one embodiment, such as Figure 1 As shown, the material turning assembly 3 also includes a support frame 32 with a receiving groove (not shown in the figure), and the material turning disc 31 is movably installed in the receiving groove.

Understandably, an external robotic arm can pick up defective components from the flipping tray 31 and place them in the waste bin 5, thus allowing the waste bin 5 to store defective components.
[0038] like Figure 2 As shown, another embodiment of the present invention also provides a material transfer mechanism, including a camera 6, a material transfer robot 7 and the aforementioned vibrating plate. The camera 6 is used to photograph the components on the flipping plate 31, and the material transfer robot 7 is used to transfer the components on the flipping plate 31.
[0039] Specifically, the camera 6 can capture images to determine whether the components on the flipping tray 31 are facing upwards, and the transfer robot 7 picks up the components facing upwards from the flipping tray 31 and assembles them onto the circuit board. In this invention, the transfer mechanism has a high degree of automation.
