Detailed Description of the Embodiment

[0034] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0035] Reference Figure 1 , a structural schematic diagram of an embodiment of an automatic feeding device of the present utility model is shown, including a vibrating tray 101, which is connected to a discharge head 103 through a conveying pipe 108; a receiving platform 201, with a receiving tray 204 provided at its upper end; the lower end of the receiving tray 204 is connected to the output end of a motor 207 or a rotary cylinder for driving the receiving tray 204 to rotate intermittently; the upper end of the receiving tray 204 is provided with receiving posts 205 arranged according to a preset rule; the receiving tray 204 is slidably arranged horizontally at the lower end of the discharge head 103; when the receiving tray 204 is in the first position and the receiving tray 204 stops rotating, the receiving posts 205 are aligned with the discharge port of the discharge head 103.

[0036] In this embodiment, an automatic feeding device is proposed, aiming to solve the problem of low efficiency in the assembly process of tire screws and nuts on an automobile production line. Specifically, the vibrating tray 101 can automatically sort the screws and nuts therein, and through the above-mentioned conveying pipe 108, the material (screw or nut) is conveyed to the position of the discharge head 103. The receiving tray 104 is in the first position and rotates under the drive of the motor 207 or the rotary cylinder, so that the receiving posts 205 on the receiving tray 204 can be aligned with the discharge port of the discharge head 103. The material is output from the discharge port to the receiving posts 205 until all the receiving posts 205 on the receiving tray 204 are loaded with materials. Then, the receiving tray 104 is moved to the second position. At this time, the screws or nuts can be taken out in batches by corresponding tools and installed on the tire, thus realizing fast and efficient installation.

[0037] Under the action of a motor or a rotary cylinder, the above-mentioned material receiving tray 204 rotates to the first position at a predetermined rhythm. At this time, the material receiving column 205 is aligned with the discharge port of the discharge head 103. In this application, a motor can be preferably used, and specifically, a 400W motor can be used to drive to ensure that the material receiving tray 204 has sufficient rotational power. Screws or nuts fall from the discharge head 103 into the material receiving column 204 until all the material receiving columns 205 have nuts or screws. Then, the material receiving tray 204 moves to the assembly position, and the screws are accurately placed in the screw holes to be assembled or the nuts are accurately placed in the positions of the assembled screws through corresponding tools, and the assembly is carried out automatically. This solves the problem of low efficiency of the manual feeding method. The automatic feeding device significantly reduces the time and labor intensity of manual operation through automatic screw supply and positioning. Through precise mechanical design and control, it improves the accuracy and consistency of screw feeding, which helps to improve the overall assembly quality; the automatic feeding device can quickly and continuously provide screws for the assembly line, greatly shortening the assembly time, reducing the dependence on manpower, especially in high-repetition assembly tasks, saving labor costs, reducing human errors through automatic precise control, improving the consistency and reliability of products. The automatic feeding device can also be adjusted according to different types of screws and screw holes to adapt to diverse production requirements.

[0038] It should be noted that the above-mentioned tool can be an electric screw tool with multiple screw positions. It is a conventional electric tool and will not be elaborated here. A magnetic suction head is provided at its corresponding position. Just align the material taking head with the material receiving column 205 to achieve one-time material taking and complete the installation of multiple nuts or screws at one time; when the above-mentioned material receiving column 205 is used for assembling nuts, it has a protrusion in the middle, which can play a role in positioning the nuts. When it is used for assembling screws, it can be hollow in the middle, and its screw rod can fall into the hollow structure, and the screw head is exposed at the upper end of the material receiving column 205 for convenient material taking. The distribution of the above-mentioned material receiving columns 205 can be based on the tire size and the corresponding screw position distribution.

Through the cooperation of the above-mentioned slide rail 202 and the slider 206, the support frame 203 can slide smoothly on it, thereby driving the above-mentioned material receiving tray 204 to move smoothly between the first position and the second position, avoiding large vibrations during movement, which may cause the nuts or screws on the material receiving column 205 to shift or fall off.

[0040] In an embodiment of the present application, it further includes a mounting plate 301, on which there is a telescopic component 303 parallel to the slide rail 202. The output end of the telescopic component 303 is connected to the support frame 203 through a connecting block 302. The above-mentioned telescopic component 303 can be a cylinder, a telescopic rod or a linear module. In the present application, a cylinder is preferably used to drive the above-mentioned support frame 203 to slide, so as to realize the translation of the above-mentioned receiving tray 204.

[0041] In an embodiment of the present application, it further includes a limit block 208. The limit block 208 is arranged at the end of the receiving platform 201, and its height is not lower than the height of the support frame 203 located at the upper end of the receiving platform 201, and is used to limit the translation of the receiving tray 204 to prevent it from translating excessively and exceeding the first position and the second position, and to prevent the slider 206 from moving out of the slide rail 202.

[0042] In an embodiment of the present application, a linear vibrator is provided at the lower end of the conveying pipe 108, and the lower end of the linear vibrator is connected to a vibration frame 109. The linear vibrator, that is, the linear feeder, also known as the linear vibrating feeder, is a mechanical device that can linearly convey the materials conveyed by the vibrating disk. It cooperates with the vibrating disk to further ensure that the materials can be conveyed to the discharging head 103 position through the conveying pipe 108.

[0043] In an embodiment of the present application, as Figure 3 shown, the discharging head 103 includes: a distributor chute 131, a first pushing cylinder 132, a pushing block 133 and a receiving rack 134; the first pushing cylinder 132 is arranged on one side of the distributor chute 131, and the receiving rack 134 is covered on the distributor chute 131; the pushing block 133 is arranged in the space between the receiving rack 134 and the distributor chute 131; the distributor chute 131 is provided with a first material hole 135, the pushing block 133 is provided with a second material hole 136, and the receiving rack 134 is provided with a third material hole 137; the third material hole 137 is connected to the conveying pipe 108 through a receiver; the pushing block 133 is connected to the piston of the first pushing cylinder 132, and the first pushing cylinder 132 drives the pushing block to make the second material hole 136 communicate with the first material hole 135 or communicate with the third material hole 137; the first material hole 135 is the discharging port.

[0044] Through the push block 133 provided in the above-mentioned distributor chute 131, the feeding of screws or nuts is controlled. Specifically, the above-mentioned distributor chute 131 is provided with a first material hole 135, and the above-mentioned material receiving rack 134 is provided with a third material hole 137. Among them, the first material hole 135 and the third material hole 137 are staggered from each other in the vertical direction; the first pushing cylinder 132 is connected with the push block 133. By pushing the above-mentioned push block 133 through the first pushing cylinder 132, the second material hole 136 of the above-mentioned push block 133 can move between the first material hole 135 and the third material hole 137. When the second material hole 136 moves to be vertically aligned with the third material hole 137, the material falls from the third material hole 135 into the second material hole 136 of the push block 133. By pushing the push block 133 through the above-mentioned first pushing cylinder 132, when the second material hole 136 is vertically aligned with the above-mentioned first material hole 135, the second material hole 136 is staggered from the third material hole 137, so that the material at the position of the third material hole 137 is blocked by the push block 133, and at the same time, the material in the second material hole 136 falls into the first material hole 135. Since the first material hole 135 is the discharge port, at this time, the material is discharged from the discharge port to the material receiving column 205 of the material receiving tray 204. Through the intermittent rotation of the cylinder in cooperation with the material receiving tray, it can achieve precise and efficient feeding.

[0046] Through the above-mentioned material bin 102, storage of materials can be carried out. When the materials in the vibrating tray 101 are insufficient, the second pushing cylinder can be cooperated to push the above-mentioned pushing plate 105, so that the materials fall from the feeding port 121 into the vibrating tray, thereby realizing automatic feeding. When the materials in the above-mentioned material bin 102 are insufficient, it is only necessary to add materials into it from its upper end, which is convenient for feeding.
