[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A bulk material feeding structure includes a base 1, a vibratory feeder 2, a continuous material transfer mechanism 3, a waste material removal module 4, and a feeding mechanism 5.

[0032] The continuous material transfer mechanism 3 includes a rotating frame 31 and a receiving assembly 32; the rotating frame 31 is rotatably mounted on the upper middle part of the base 1; multiple sets of receiving assemblies 32 for receiving materials are evenly installed in a circular array on the rotating frame 31 at equal intervals.

[0033] The right side of the rotating frame 31 is designated as the loading station; the rear side of the rotating frame 31 is designated as the unloading station.

[0034] The discharge end of the vibratory feeder 2 is aligned with the loading station;

[0036] A waste removal module 4 for collecting waste is installed on the upper left side of the base 1;

[0037] A material feeding mechanism 5 is installed on the upper rear side of the base 1 to facilitate material feeding;

[0038] In this invention, the loose material from the chip mounter is moved to the receiving component 32 at the loading station by the vibratory feeder 2; then the receiving component 32 fixes the material; then the rotating frame 31 rotates, and the receiving component 32 with the material installed rotates together with the rotating frame 31. During the rotation of the material, the operator can perform performance testing on the material; until the material moves to the waste rejection module 4.

[0039] If the material performance test fails, the receiving component 32 will release the material from its fixation, thereby automatically removing the unqualified material.

[0040] If the material performance test is qualified, the rotating frame 31 will continue to work and drive the material to the position of the feeding mechanism 5. Then the receiving component 32 will place the material on the feeding mechanism 5, and then the material will be removed through the feeding mechanism 5. By repeating the above operation, the continuous automatic feeding of the loose material of the chip mounter can be realized. In addition, through the cooperation of the rotating frame 31 and the receiving component 32, the device can automatically reject unqualified products and ensure the quality of material supply.

[0041] like Figures 1-5As shown, a rotary joint 311 for distributing air to the receiving assembly 32 is fixedly installed on the rotating frame 31. A vacuum breaker valve 312 for controlling different receiving assemblies 32 is also fixedly installed on the rotating frame 31. The rotary joint 311 is connected to an external vacuum pump and is connected to the receiving assembly 32. The vacuum breaker valve 312 is also connected to the receiving assembly 32.

[0042] like Figures 1-5 As shown, the receiving assembly 32 includes a mounting base 321, a pneumatic moving base 322, a return spring 323, a picking rod 324, and a suction cup 325. The mounting base 321 is fixedly installed on the edge of the rotating frame 31, and the pneumatic moving base 322 is fixedly installed on the rotating frame 31. The output end of the pneumatic moving base 322 is fixedly connected to the upper end of the picking rod 324. The picking rod 324 passes through the pneumatic moving base 322 and is fitted with a return spring 323. A suction cup 325 for picking up materials is fixedly installed at the bottom of the picking rod 324. One end of the return spring 323 is fixedly connected to the mounting base 321, and the other end of the return spring 323 is fixedly connected to the suction cup 325. The rotary joint 311 and the vacuum breaking valve 312 are connected to the picking rod 324.

[0043] like Figures 1-5 As shown, the pneumatic moving seat 322 includes a moving cylinder and a moving seat. The moving cylinder is fixedly mounted on the rotating frame 31, and the moving seat is fixedly mounted on the output end of the moving cylinder. The upper end of the picking rod 324 is fixedly connected to the moving seat.

[0044] like Figures 1-5 As shown, the waste removal module 4 includes a waste bin 41, which is fixedly installed on the base 1 by a support rod; the waste bin 41 is aligned with the material picking rod 324 located above the waste bin 41.

[0045] like Figures 1-5 As shown, the feeding mechanism 5 includes a feeding platform 51, a positive pressure blowing pipe 53, a vacuum suction pipe 54, and a separating block 55. The feeding platform 51 is fixedly installed on the base 1. A feeding trough 52 is provided inside the feeding platform 51. The front end of the feeding platform 51 is aligned with the material picking rod 324 located at the feeding station. The separating block 55 is fixedly installed at the rear end of the feeding platform 51. A positive pressure blowing pipe 53 for blowing air into the feeding trough 52 is fixedly installed at the front end of the feeding platform 51. A vacuum suction pipe 54 communicating with the bottom of the feeding trough 52 is fixedly installed on the feeding platform 51.

[0046] Both the positive pressure blowing pipe 53 and the vacuum suction pipe 54 are externally connected to the air pump;

[0047] In this invention, the loose material from the chip mounter is moved to below the suction cup 325 at the loading station via the vibratory feeder 2; then, the pneumatic moving seat 322 drives the picking rod 324 and the suction cup 325 to move vertically downward, at which time the return spring 323 is stretched; the rotary joint 311 works to create a vacuum effect inside the picking rod 324, at which time the suction cup 325 will adsorb and fix the material; then, the pneumatic moving seat 322 drives the picking rod 324 and the suction cup 325 to return upward, and the return spring 323 returns to its original position.

[0048] Then the rotating frame 31 rotates, causing the material to rotate as well; during the rotation of the material, the operator can perform performance testing on the material; until the material moves to the position above the waste bin 41;

[0049] If the material performance test fails, the feed rod 324 and suction cup 325 will release the adsorption and fixation of the material, and the unqualified material will fall into the waste bin 41, automatically removing the unqualified material and ensuring the quality of the material supply.

[0050] If the material performance test is qualified, the rotating frame 31 will continue to work and move the material to the unloading station, and at this time the material is above the unloading platform 51; then the vacuum breaking valve 312 will work to break the vacuum effect in the picking rod 324, and then the suction cup 325 will release the adsorption and fixation effect on the material; at the same time, the vacuum suction pipe 54 will work to create negative pressure in the unloading trough 52, causing the material to fall into the unloading trough 52; then the positive pressure blowing pipe 53 will work to blow air from the front to the rear of the receiving component 32, and at this time the gas will carry the material to move quickly to the rear position; the unloading operation is completed.

[0051] By combining the positive pressure blowing pipe 53 and the vacuum suction pipe 54, the residence time of materials in the feeding trough 52 is reduced, and the feeding efficiency is improved; it also improves the accuracy of materials entering the feeding trough 52, further enhancing the practicality of the device.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
