[0028] The following elaborates on the preferred embodiments of the present invention in conjunction with the drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0029] Embodiment:

[0030] This embodiment introduces the structure of an automatic feeding device.

[0031] As Figure 1 shown, Figure 1It is a schematic three-dimensional structure diagram of an automatic feeding device of the present invention. An automatic feeding device includes: a vibrating bowl 1, a feeding device, and a pneumatic manipulator picking device 12. The vibrating bowl 1 is connected to the feeding device, and the pneumatic manipulator picking device 12 is located in front of the feeding device. The workpiece is fed into the feeding device through the vibrating bowl 1. The forward and reverse directions of the spring workpiece have been processed by the vibrating bowl before being fed into the feeding device, and the spring workpiece will be arranged in a directional manner and conveyed into the feeding device. After the feeding device discharges the workpiece, the workpiece is picked up by the pneumatic manipulator picking device 12 and fed into the fixture of the lathe spindle 7 to be stably clamped, and the turning tool device 8 on the lathe processes the head of the spring workpiece. In this process, automatic feeding, clamping, and processing of the workpiece head are realized, reducing manual participation and improving processing accuracy and production efficiency.

[0032] As Figure 2 , 3 shown, Figure 2 it is a schematic diagram of discharging of the automatic feeding device shown in the present invention, Figure 3 and it is a schematic diagram of the structure of the first ejector pin and the second ejector pin in the present invention. In a preferred embodiment, the feeding device includes a first discharging device 3 and a second discharging device 9. The first discharging device 3 is located above the second discharging device 9, and both the first discharging device 3 and the second discharging device 9 are driven by a pneumatic device 4.

[0033] A vertically penetrating discharging channel 19 is provided inside the first discharging device 3 to ensure that the direction of the workpiece does not change during the feeding process. The discharging channel 19 corresponds to the feeding port of the vibrating bowl 1, and the workpiece enters the discharging channel through the vibrating bowl.

[0034] In order to control the feeding order, feeding frequency of the spring workpiece and facilitate subsequent workpiece clamping to ensure accuracy, a first discharging ejector pin 14 and a second discharging ejector pin 15 are provided in the first discharging device 3. The first discharging ejector pin 14 is located above the second discharging ejector pin 15. The first discharging ejector pin 14 and the second discharging ejector pin 15 are connected up and down by a connecting rod 16. The cylinder device 4 drives the connecting rod 16 to drive the first discharging ejector pin 14 and the second discharging ejector pin 15 to reciprocate, and push the workpiece to the second discharging device 9. A discharging hole 17 is provided on the second discharging ejector pin 15.

[0035] Under the action of the first blanking ejector pin and the second blanking ejector pin, the workpieces enter the first blanking device through the vibrating bowl one by one, with only one entering each time, ensuring the feeding frequency and improving the clamping efficiency and accuracy. The working principle of the first blanking ejector pin and the second blanking ejector pin: When the first workpiece enters the blanking channel 19, under the action of the cylinder device 4, the first blanking ejector pin 14 and the second blanking ejector pin 15 are moved to one side of the blanking channel 19. However, since the length of the second blanking ejector pin 15 is designed to be longer than that of the first blanking ejector pin 14 during design, the second blanking ejector pin 15 does not completely move away from the blanking channel 19. Therefore, the first workpiece entering the blanking channel 19 falls onto the second blanking ejector pin 15; the feeding device operates continuously and automatically. Immediately afterwards, the cylinder device drives the first blanking ejector pin 14 and the second blanking ejector pin 15 to reset. At the same time, the second workpiece enters the blanking channel 19 and is held by the first blanking ejector pin 14. The first workpiece on the second blanking ejector pin 15 falls through the blanking hole 17 to the second blanking device 9 as the second blanking ejector pin moves. The first blanking ejector pin and the second blanking ejector pin cooperate with the cylinder device to repeat the above movements, ensuring the sequential discharging of the spring workpieces, enabling accurate clamping after picking up the workpieces and also improving the discharging efficiency.

[0036] The structural design of the first blanking device solves the problems of the complex operation of fixing spring workpieces with the help of auxiliary tools such as mother and son sleeves during clamping and the difficulty in ensuring the clamping accuracy in the prior art. In the present invention, by providing a vertically penetrating blanking channel in the first blanking device, it is ensured that the direction of the spring workpieces does not change during the feeding process from the vibrating bowl to the discharging, guaranteeing the accuracy and consistency during clamping, ensuring the accuracy of workpiece processing, and thus improving the product quality.

[0037] As Figure 4 、 5 shown, Figure 4 is a schematic diagram of the cooperation between the cam structure and the rotatable station in the present invention, Figure 5 is a schematic diagram of another angle of the cooperation between the shown cam structure and the rotatable station. In the preferred embodiment, in order to facilitate picking up the workpieces, improving the rapid clamping after discharging and the clamping accuracy, a second blanking device is provided below the first blanking device. The second blanking device 9 includes a rotatable station 6 and a cam structure 5. The rotatable station 6 is installed on the mounting vertical plates 18 on both sides of the rotatable station 6 through bearings, and the rotatable station can rotate along the bearings. The rotatable station 6 is located on the cam structure 5. When the cylinder device 4 drives the cam structure 5 to move, the cam structure 5 pushes the rotatable station 6 to flip. A workpiece picking port 10 is provided on the rotatable station 6, and the workpiece picking port 10 receives the workpieces discharged from the first blanking device 3.

[0038] In a preferred embodiment, the rotatable station 6 can be flipped by 90° under the push of the cam structure 5. After flipping, the material taking port 10 faces the pneumatic manipulator material taking device 12. Driven by the X-axis motor 11 and the Z-axis motor 13, the pneumatic manipulator material taking device 12 sends the workpiece to the fixture of the lathe spindle 7 for stable clamping, so that the turning tool device can process the workpiece subsequently.

[0039] Working principle: After being processed by the vibrating disk 1, the workpieces enter the blanking channel 19 in an orderly and oriented manner. The first blanking ejector pin 14 and the second blanking ejector pin 15 cooperate with the cylinder device 4 to control the workpieces to be discharged one by one. The workpieces fall into the material taking port 10 on the rotatable station 6 one by one. The cylinder device 4 drives the cam structure 5 to move backward, and the rotatable station 6 rotates 90° in the direction opposite to the cam structure 4. The material taking port 10 just faces the pneumatic manipulator material taking device 12. Driven by the motor, the pneumatic manipulator material taking device 12 sends the workpiece to the lathe for clamping and completes the processing of the workpiece.

[0040] In the present invention, by arranging a second blanking device below the first blanking device and arranging a material taking port on the rotatable station, the material taking port is located directly below the blanking channel. After feeding by the first blanking device, the workpieces fall accurately and stably into the material taking port, and are accurately clamped by the pneumatic manipulator material taking device and sent to the lathe for clamping for subsequent processing. The whole process is automated, and the workpieces will not change direction from feeding to clamping. The clamping position of the workpieces is also determined, and all workpieces are positioned consistently, which improves the consistency of workpiece clamping and further improves the consistency of workpiece processing quality.

[0041] In a preferred embodiment, we also have a sensor on the feeding device. The sensor detects whether there is a workpiece in the feeding device. When there is a workpiece, the vibrating disk stops moving. When there is no workpiece, the vibrating disk moves for feeding, improving the feeding efficiency.

[0042] In the present invention, regarding the layout of the position relationship between the feeding device, the pneumatic manipulator material taking device, and the lathe, it can be reasonably arranged according to the actual production space. The present invention does not limit the layout position, and the cooperation between each action is also controlled by the connected numerical control lathe signal program. The application of the cylinder device, the pneumatic manipulator material taking device, the lathe spindle, and the turning tool device is well known to those skilled in the art, and no improvement has been made in the present invention, so the detailed structure is not described in detail and is not shown in the drawings.

[0043] The solution of the present invention has been put into use and has been successfully applied to the production and processing of batch spring parts. Through actual production statistics, it is found that the production efficiency has increased by 30% and the number of operating personnel has been reduced by 80% by using this device, which improves the market competitiveness of the enterprise and greatly improves the production efficiency. Compared with the prior art that relies on manual operation and has limited production capacity, the automated continuous processing of the present invention not only greatly saves labor costs but also can meet the demand for mass production.

[0044] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
