[0019] The following are specific embodiments of the present invention, in combination with the accompanying drawings, to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0020] As Figure 1 shown, it is a schematic diagram of the overall structure, and the entire structure includes: a conveying mechanism 4, a magazine unlocking mechanism 5, a blanking unlocking mechanism 3, and a double magazine 1.

[0021] As Figure 2 shown, the conveying mechanism consists of a feeding base 31, a discharging platform 15, a blocking air cylinder 16, a blocking block 32, a belt 11, sensors A12, B13, C14, and a material return box 8;

[0022] The conveying mechanism 4 is mainly used to judge the transmission position of parts and transmit parts. The conveying mechanism 4 is arranged on the feeding base 31, and its power is provided by a motor; the motor drives the belt 11 to rotate through gear transmission, and transports the materials to the discharging platform 15. A blocking air cylinder 16 is arranged below the discharging platform 15, and a blocking block 32 is installed on the blocking air cylinder 16 to block the parts to be discharged and the discharged parts. Two sensors 13 and 14 are arranged on the discharging platform. The sensor 14 is used to judge whether there is a discharged part. When the discharged part is taken away, the blocking air cylinder descends to release the part to be discharged; the sensor 13 is used to judge whether the part to be discharged is conveyed out of the blocking position. When the sensor senses the material twice continuously, the blocking air cylinder 16 rises to block the part to be discharged; the sensor 12 is used to judge whether the part is full of materials. When it is full of materials, the blanking unlocking mechanism 3 does not act and does not release new parts. When the automatic feeding mechanism encounters a stop, the belt can reversely transport the parts to the material return box 8 to recycle the excess parts.

[0023] As Figure 3 shown, the double magazine 1 consists of a material pipe 19, a mounting side plate 20, a loading mounting plate 18, a handle 17, a magazine unlocking block 22, and a magazine base 21.

[0024] The automatic feeding mechanism is provided with two magazines A and B with the same structure for storing parts. The double magazine 1 is provided with a plurality of material pipes 19 for storing parts, and the parts can be placed into the material pipes 19 from the feeding port of the loading mounting plate 18.

[0025] As Figure 4 shown, a sliding push block 28 is arranged in the magazine unlocking block 22 of the double magazine 1; a sliding unlocking bar 26 is arranged between the magazine base 21 and the discharging plate 25. The sliding push block 28 and the sliding unlocking bar 26 are installed together, and the unlocking bar 26 slides in the discharging plate 25 by pushing the sliding push block 28 with an air cylinder.

[0026] As Figure 5The magazine unlocking mechanism shown consists of a magazine door 34, a receiving plate 36, a guiding bottom plate 35, pen-shaped cylinders 29 and 30, sensors 32 and 33, and a magazine unlocking handle. The magazine unlocking mechanism 5 is used to place the magazine and unlock the magazine to release parts.

[0027] As Figure 2 The blanking unlocking mechanism shown consists of blanking unlocking push blocks 7 and 9, a cylinder, and a slider. The push teeth of the blanking unlocking push blocks 7 and 9 are engaged into the receiving plate 36, and the parts are pushed under the drive of the cylinder. The parts move horizontally onto the belt 11. The blanking unlocking mechanisms A and B can move independently.

[0028] The automatic feeding mechanism realizes sustainable and uninterrupted feeding under the unlocking of the magazine unlocking mechanism 5 and the blanking unlocking mechanism 3. The principle is as follows: Place the double magazine 1 in the magazine unlocking mechanism 5, push the magazine unlocking handle 37 to drive the magazine door 34, so that the double magazine 1 is in a fixed state. At this time, the double magazine 1 is in the initial position, and the discharge port of the sliding unlocking strip 26 is staggered from the discharge port of the discharge plate 25, and parts cannot be released; when the sensor 12 of the conveying mechanism determines that the material is not full, the magazine unlocking mechanism 5 releases the parts, and one of the pen-shaped cylinders 29 and 30 pushes the sliding push block 28, so that the discharge port of the sliding unlocking strip 26 coincides with the discharge port of the discharge plate 25, and the parts are released onto the receiving plate 36 at the lower layer of the guiding bottom plate 35 of the magazine unlocking mechanism 5. The sensors 32 and 33 installed on the guiding bottom plate 35 sense that the parts have fallen onto the receiving plate 36, and one of the blanking unlocking push blocks 7 and 9 of the blanking unlocking mechanism 3 pushes the parts and pushes the parts onto the belt 11; the belt 11 transports the parts to the discharge platform.

[0029] It should be noted here that when releasing parts, the parts in one magazine are preferentially and continuously released to ensure that the parts in a single magazine are released completely. When replacing the magazine with empty parts with a magazine full of parts, the other magazine starts to release parts under the unlocking of the magazine unlocking mechanism 5 and the blanking unlocking mechanism 3, realizing sustainable and uninterrupted feeding.

[0030] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
