Description

Technical Field

[0001] The utility model relates to the technical field of bolt feeding, in particular to an automatic feeding device for automobile production. Background Art

[0002] Automobiles consist of a variety of parts, such as engine system components, transmission system components, brake system components, suspension system components, electrical system components, body and interior components, cooling system components, fuel system components, steering system components, etc. Bolts are required to mount each component on the vehicle frame and to assemble the components. Therefore, bolts are used in large quantities in automobile production.

[0003] Currently, there are various parts loading devices on automobile production lines, such as various arm machines, which use the arm machines to place larger parts in the corresponding positions on the frame. This method reduces the labor intensity of workers. However, there is no corresponding loading device for bolts, which are used in large quantities. During vehicle production, workers carry bags on their backs and store the bolts in the bags or in boxes. Both bags and boxes have a small storage capacity, so workers need to add bolts frequently. In addition, when using bolts, workers' palms reach into the bag or box to grab multiple bolts at a time. Due to the threads on the bolt surface, there is a large friction coefficient, and the bolts are placed in a disorderly manner. Therefore, when grabbing bolts, the palms are easily worn and even injured.

[0004] In addition, manufacturers with strong strength generally use robots to install bolts on vehicles. If the bolts are placed in a disorderly manner, it is not conducive to the robot to grab the bolts. Although a loading device for bolts has been disclosed on the market, such as a Chinese patent with publication number CN111300000A, which discloses an automatic loading device for bolts and nuts, comprising a horizontal sliding assembly and a bolt and nut grabbing assembly provided on the workbench frame, the bolt and nut grabbing assembly moves up and down along the boom, the boom slides along the axial direction of the support plate, and the support plate slides along the length direction of the horizontal frame, and cooperates with each other to complete the transfer of bolts and nuts on both sides of the workbench to the workpiece to be processed on the workbench; the structure is reasonably set up and the degree of automation is high. It is not only easy to operate, but also simple in structure and low in cost. As can be seen from the above-mentioned disclosed technical solution, the device is large in size and is not suitable for installation on a dense production line. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] The following will be further described in conjunction with the drawings and specific embodiments:

[0029] Embodiment 1

[0030] In order to facilitate the staff to pick up bolts or facilitate the manipulator to grasp bolts to complete the installation of automotive parts, this embodiment provides a feeding device for bolts. This feeding device can control the arrangement of bolts distributed in a chaotic manner so that the staff or the manipulator can accurately pick them up. The specific technical solution is as follows.

[0031] As Figure 1 , Figure 2 shown, the feeding device includes a bracket 1, a cylinder 2, a lifting arc plate 3 and a guiding device 6. A plurality of universal wheels 12 are provided below the bracket 1, and there is a stepped structure around the top. A central column 11 is provided inside the bracket 1, and the top of the central column 11 is flush with the bottom surface of the stepped structure. Therefore, when the lower end of the cylinder 2 extends into the stepped structure, the top of the central column 11 fits against the bottom surface of the cylinder 2. This setting can stably support the bottom surface of the cylinder 2 and provide support for it to carry most bolts. The guiding device 6 is set in a structure that is high in the middle and low at both ends, and is located inside the cylinder 2 and centered on the same vertical axis. Therefore, a gap is formed between the guiding device 6 and the cylinder 2. The size of the bottom of this gap is the smallest, and the space with this smallest size can accommodate the lifting arc plate 3, that is, the lifting arc plate 3 can rise from the bottom of the cylinder 2 and can also descend from the top of the cylinder 2 to the bottom. Since the upper side of the lifting arc plate 3 is open, that is, the cross-section is a U-shaped structure, during the rising process of the lifting arc plate 3, the rod bodies of some bolts will extend into the lifting arc plate 3, and the tops are supported above the lifting arc plate 3. Therefore, the bolts can be arranged on the lifting arc plate 3 for use by personnel or robotic arms.

[0032] In order to gather multiple screws supported on the lifting arc plate 3 together, there is a height difference at both ends of the upper side of the lifting arc plate 3. Therefore, the bolts will move along the lifting arc plate 3 to the bottom. To prevent the bolts from detaching, the bottom of the lifting arc plate 3 can be set as a closed structure.

[0033] As Figure 5As shown, in order to prevent the remaining bolts from occupying the space in which the lifting arc plate 3 is lifted after it is raised, the central angle of the lifting arc plate 3 is greater than 180°, and the outer diameter is the same as the inner diameter of the cylinder 2. Therefore, the lifting arc plate 3 is in sliding contact with the inner side surface of the cylinder 2, blocking the channel for the bolts to fall through the gap between the lifting arc plate 3 and the cylinder 2. In addition, a baffle 31 is provided below the lifting arc plate 3. The baffle 31 is also provided with an arc structure, and the central angle of the baffle 31 is the same as the central angle of the lifting arc plate 3. At the same time, the inner diameter of the baffle 31 is the same as the inner diameter of the lifting arc plate 3. Therefore, under the cooperation of the baffle 31 and the lifting arc plate 3, the bolts can be blocked from moving directly below the lifting arc plate 3 during the lifting process of the lifting arc plate 3.

[0034] like Figure 2 、 Figure 3 、 Figure 5 As shown, in order to control the lifting and lowering of the lifting arc plate 3, a threaded tube 32 is provided at the bottom of the baffle 31, and an arc-shaped hole 24 is provided on the bottom surface of the cylinder 2. The lower end of the baffle 31 is provided through the arc-shaped hole 24, so as to facilitate the lifting and lowering of the baffle 31 along with the lifting arc plate 3. In addition, a threaded rod 13 is provided on the bracket 1, and the bottom of the threaded rod 13 is connected to the bracket 1 through a bearing. In addition, a motor is also provided on the bracket 1, and the motor is connected to the threaded rod 13. The connection method is conventional, such as using a sprocket, pulley, etc. Therefore, under the operation of the motor, the threaded rod 13 can be controlled to rotate forward and reverse, forcing the baffle 31 to drive the lifting arc plate 3 to rise and fall.

[0035] like Figure 1 、 Figure 4 As shown, in order to make the bolts in the cylinder 2 have a tendency to move to the lifting arc plate 3, the guide device 6 includes a curved plate 61 and a filling plate 62. A sleeve 63 is provided on the inner side of the curved plate 61, and a connecting rod 23 is installed on the bottom surface of the cylinder 2. The sleeve 63 is sleeved on the connecting rod 23. Therefore, the curved plate 61 is stably installed in the cylinder 2, and the bolts always have a tendency to move downward along the curved plate 61, so that the bolts can move to the lifting arc plate 3. The filling plate 62 is installed on the curved plate 61 and is arranged in contact with the inner side surface of the cylinder 2. At the same time, the filling plate 62 is arranged in the notch of the lifting arc plate 3, and the top surface of the filling plate 62 is flush with the bottom surface of the splicing plate 22. Therefore, the bolts will not accumulate in the notch of the lifting arc plate 3 and affect the movement of the lifting arc plate 3.

[0036] In order to enable the lifting arc plate 3 to keep up with the needs of the production line, the bolts arranged on the lifting arc plate 3 can be moved to other positions so that the staff or robot can take them without affecting the operation of the lifting arc plate 3. Therefore, a splicing plate 22 can be set on the top of the cylinder 2, and an arrangement plate is set on the outside of the cylinder 2. The arrangement plate can be connected to the end of the lifting arc plate 3 through the splicing plate 22. The cross-section of the arrangement plate and the splicing plate 22 is the same as the end face of the lifting arc plate 3. Therefore, when the end of the lifting arc plate 3 is docked with the splicing plate 22, under the action of the gravity of multiple bolts, the bolts on the lifting arc plate 3 can be moved to the arrangement plate. At this time, the lower end of the lifting arc plate 3 needs to be set as an opening, which can be set directly opposite and in contact with the end of the splicing plate 22.

[0037] Example 2

[0038] like Figure 3 、 Figure 6 As shown, based on Example 1, in order to reduce the space occupied by the device, the arrangement plate can be set as a first arrangement plate 5. The first arrangement plate 5 is set as an annular structure with an inner diameter equal to the outer diameter of the cylinder 2. At the same time, it is supported on the supporting ring plate 21 of the cylinder 2, so that the first arrangement plate 5 is stably installed relative to the cylinder 2. A notch 51 is provided on the inner side wall of the first arrangement plate 5. The notch 51 is directly opposite to the end of the splicing plate 22 and is located at the highest point of the first arrangement plate 5. Therefore, the bolts moved from the splicing plate 22 to the first arrangement plate 5 can be moved to other positions on the first arrangement plate 5.

[0039] Example 3

[0040] like Figure 7 As shown, based on Example 1, the arrangement plate can also be set as a second arrangement plate 7, which is set parallel to the diameter of the cylinder 2 and fixedly connected to the splicing plate 22. At the same time, the end away from the splicing plate 22 is set as a closed structure, so that the bolts can be stably placed on the second arrangement plate 7.

[0041] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
