[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figure 1 、 Figure 2 As shown, an automatic bolt loader includes a housing 1, in which a reversing plate 2 and a bolt bucket 3 are placed vertically side by side. A cover plate 13 is provided on the housing 1, and the cover plate 13 is opposite to the opening of the bolt bucket 3. In order to facilitate installation, the middle part of the reversing plate 2 is connected to the housing 1 through a bearing 23. The reversing plate 2 is driven by a motor to rotate relative to the bolt bucket 3. Figure 5 , the inner cavity of the flip disk 2 is fixedly provided with a rotating blade 21 with an arc, and the rotating blade 21 can be multiple and evenly spaced. The bolt bucket 3 is provided with an inclined surface 31 pointing to the flip disk 2, so as to ensure that the bolt slides naturally into the flip disk 2 under natural gravity. A vibration disk 4 is fixedly installed in the shell 1 and is located outside the bolt bucket 3. The vibration disk 4 is connected to the inclined bolt guide rail 5. The width of the gap of the bolt guide rail 5 is greater than the width of the bolt rod and less than the width of the bolt head. The bolt guide rail 5 extends downward from the middle of the flip disk 2 through the bolt bucket 3 to the conveying box 6. Figure 7The conveying box 6 is provided with a telescopic cylinder 7, and the gas rod 71 on the telescopic cylinder 7 is provided with a accommodating groove 711 for accommodating bolts. The conveying box 6 is provided with a transverse groove 61, and the gas rod 71 on the telescopic cylinder 7 can push the accommodating groove 711 from one end of the transverse groove 61 to the other end. A vacuum tube 8 for conveying bolts is provided above the other end of the transverse groove 61.

[0029] Reference Figure 2 To drive the reversible disc 2 to rotate, a reversing motor 9 is provided within the housing 1. The reversing motor 9 is connected to a gear 91. A gear ring 22 is provided on the outside of the reversible disc 2 and meshes with the gear 91. Furthermore, to ensure smoother operation, a left gear 33 and a right gear 32 are provided on the left and right sides of the upper portion of the bolt bucket 3, respectively. The left gear 33 and the right gear 32 mesh with the gear ring 22 on the outside of the reversible disc 2, respectively.

[0030] Reference Figure 3 、 Figure 4 Since the width of the gap of the bolt guide rail 5 is greater than the width of the bolt rod and smaller than the width of the bolt head, the bolt with the head facing up and the rod facing down will fall into the gap, so that the bolt can only slide down with the rod facing down, and the others will lie flat on the bolt guide rail 5. In order to remove the bolts lying flat on the bolt guide rail 5, a connecting shaft 34 is passed through the bolt bucket 3, and a brush 35 driven by a motor 36 is fixedly mounted on the connecting shaft 34. During the rotation of the brush 35, the bolts lying flat on the bolt guide rail 5 can be removed. In this example, the motor 36 is installed on the side wall of the bolt bucket 3 and is connected to the connecting shaft 34 through a connecting rod structure, thereby controlling the rotation of the connecting shaft 34.

[0031] Reference Figure 6 In order to prevent the bolts from squeezing each other and raising some bolt heads when they slide down, a baffle 10 is provided at one end of the bolt guide rail 5 located in the conveying box 6. The baffle 10 is located 1-2 mm above the gap of the bolt guide rail 5. In addition, the baffle 10 and the bolt guide rail 5 are connected by a self-resetting hinge 101. This design allows the baffle 10 to be rotated by the self-resetting hinge 101 when the equipment is debugged or shut down, so that the bolts that have not been conveyed can be taken out.

[0032] Reference Figure 6 The bolt guide rail 5 is located at one end of the middle part of the flip plate 2 and is Y-shaped. This design can smoothly receive the fallen bolts, and the bolt guide rail 5 is at a certain angle to the horizontal. The bolts slide down under the combined action of their own gravity and the vibration plate 4. In order to ensure the sliding effect, a pneumatic nozzle parallel to the gap can also be provided at one end of the bolt guide rail 5 located at the baffle 10.

[0033] In addition, a positioning sensor 51 is provided at one end of the bolt guide rail 5 located on the baffle 10. When the number of bolts in the bolt guide rail 5 accumulates to the position of the positioning sensor 51, the positioning sensor 51 will control the flip motor 9 and the motor 36 to stop running to prevent too many bolts in the bolt guide rail 5.

[0034] The present invention works as follows:

[0035] 1. Pour the bolts into the bolt bucket 3. The bolt bucket 3 is provided with an inclined surface 31 pointing towards the flip plate 2, so that the bolts can slide naturally into the flip plate 2 under natural gravity.

[0036] 2. Start the flip motor 9, and drive the gear ring 22 outside the flip disk 2 through the gear 91 to rotate the flip disk 2. At this time, the rotating blades 21 in the cavity of the flip disk 2 will drive the bolts to flip and fall naturally from a high place. Since the width of the gap of the bolt guide rail 5 is greater than the width of the bolt rod and smaller than the width of the bolt head, the bolts with the head facing up and the rod facing down will fall into the gap, so that the bolts can only slide down with the rod facing down, and the others will lie flat on the bolt guide rail 5.

[0037] 3. Since the bolt guide rail 5 extends downward from the middle of the flip plate 2 through the bolt bucket 3 to the conveying box 6, the bolts slide down faster under the combined action of their own gravity, the vibration plate 4 and the pneumatic nozzle.

[0038] 4. As the bolts slide down the bolt guide rail 5, a connecting shaft 34 is connected to the bolt bucket 3. A brush 35 driven by a motor 36 is fixedly mounted on the connecting shaft 34. During the rotation of the brush 35, the bolts lying flat on the bolt guide rail 5 can be removed, while the bolts vertically in the gap of the bolt guide rail 5 can pass smoothly.

[0039] 5. When the bolt slides down into the receiving groove 711 for receiving the bolt, the gas rod 71 on the telescopic cylinder 7 can push the receiving groove 711 from one end of the transverse groove 61 to the other end, that is, push it to the bottom of the vacuum tube 8. The vacuum tube 8 starts adsorption and transfers the bolt to the conveying pipeline.

[0040] This product can arrange the bolts with their heads facing upwards and their rods facing downwards in order through the bolt guide rail 5, and finally realize the long-distance and one-by-one transportation of the bolts through the vacuum tube 6, avoiding the time-consuming and labor-intensive manual loading of the bolts in the past, and effectively realizing the automation of bolt installation and digital assembly.

[0041] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
