Description

Technical Field

[0001] This utility model relates to a polishing device, and more specifically, to a chip mounter feeding device. Background Technology

[0002] During the placement process, small components such as resistors and capacitors require a vibratory feeder to arrange them and deliver them to the placement machine's feed port. However, most feeding systems use a single vibratory feeder, whose continuous vibration moves the material along a feed track to the machine's feed port. The maximum space the vibratory feeder can hold is limited by the material's shape, weight, or flowability. Adjusting the total material load in the vibratory feeder helps prevent uneven material accumulation, but this necessitates frequent manual replenishment to ensure stable feeding.

[0003] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a chip mounter feeding device includes a vibrating feeder 1 and a linear vibrating feeder 2. The inlet 13 of the linear vibrating feeder 2 is connected to the outlet of the vibrating feeder 1. The vibrating feeder 1 is provided with a hopper 12 for containing materials. A feeding support 3 is provided on one side of the vibrating feeder 1. A conveyor 4 is slidably connected to the feeding support 3. One end of the conveyor 4 is provided with an outlet 41, which extends directly above the hopper 12. A feeding bin 5 is provided on the conveyor 4. The feeding bin 5 includes side walls 51 extending upward along both sides of the conveyor 4, a front baffle 52 connecting the first ends of the two side walls 51, and a rear baffle 54 connecting the last ends of the two side walls 51. The front baffle 52 is located in front of the outlet 41 and forms a channel 42 for material to pass through between it and the outlet 41. The channel 42 is connected to the hopper 12.

[0020] Furthermore, such as Figure 4 and Figure 5 As shown, a material limiting baffle 53 is also provided above the output port 41. The two sides of the material limiting baffle 53 are fixed to the two side walls 51 respectively. A gap 100 is formed between the lower surface of the material limiting baffle 53 and the conveyor table 4 to allow material to move through. Accordingly, when the material passes through the gap, the material limiting baffle 53 restricts the output of the material, accurately controls the supply of the material, and ensures the stability and sustainability of the material supply of the vibrating feeder 1.

[0021] Furthermore, such as Figure 5 As shown, the conveyor table 4 includes a conveyor belt 412, two drive shafts 411 rotatably connected to the feeding bracket 3, and a motor 413. The conveyor belt 412 is tensioned on the two drive shafts 411. The motor 413 is installed on one side of the feeding bracket 3, and its output end is fixedly connected to either drive shaft 411 to drive the drive shaft 411 to rotate.

[0022] Furthermore, the top of the feeding hopper 5 is rotatably connected to a top cover 52 for sealing the top.

[0023] Furthermore, such as Figure 3 As shown, the inlet 13 of the linear vibrating feeder 2 is provided with a conveying track 212, and the conveying track 212 has a conveying trough 213. One end of the conveying trough 213 is connected to the outlet of the vibrating feeder 1, and the other end 211 is connected to the feed port of the chip mounter.

[0024] Furthermore, such as Figure 6As shown, the bottom of the linear vibrating feeder 2 is equipped with a height adjustment mechanism, which includes a mounting bracket 26, an upper mounting base plate 22, a lower mounting base plate 23, and an adjusting screw 24. The mounting bracket 26 is fixed to the ground; the upper mounting base plate 22 and the lower mounting base plate 23 are tightened to the upper and lower ends of the adjusting screw 24 by nuts 25; the linear vibrating feeder 2 is mounted on top of the upper mounting base plate 22; the lower mounting base plate 23 is fixedly connected to the mounting bracket 26. Therefore, by adjusting the position of the upper mounting base plate 22 on the adjusting screw 24, the height of the linear vibrating feeder 2 can be adjusted, ensuring the rationality and stability of the chip mounter feeding device structure.

[0025] In summary, this application adds a feeding bin 5 to the feeding device, with the conveyor 4 serving as the bottom of the feeding bin 5. The material is placed inside the feeding bin 5. When the weight sensor on the vibrating feeding plate 1 senses that the material is insufficient, the conveyor 4 is automatically activated to transport the material to the hopper 12 of the vibrating feeding plate 1. The material conveying amount is precisely controlled, which can effectively avoid uneven material accumulation. There is no need for frequent manual operation to replenish the material, reducing the labor intensity of workers.
