Description

Technical Field

[0001] This application relates to the field of automation, and more particularly to a component for quantitative feeding of parts. Background Technology

[0002] In industrial automated production, it is sometimes necessary to feed, handle, and assemble semi-finished parts. For example, when producing certain specialized products, selected, high-quality semi-finished parts need to be periodically and quantitatively fed onto a conveyor belt according to a set quantity and time interval to facilitate processing at the next workstation. In military production, for instance, primers used to attach to the base of bullets require timed and quantitative feeding during transport. Feeding too few primers would affect production efficiency, while feeding too many would lead to accumulation and create hazards. Traditional processes are generally done manually, which is inefficient and subject to many uncontrollable human factors, severely impacting overall production efficiency. Summary of the Invention

[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] Please refer to Figures 1 to 7 As shown, this application discloses a parts quantitative feeding assembly, which can be used in conjunction with a conveyor belt to feed parts onto the conveyor belt 11 in a timed and quantitative manner. This allows the parts to be processed at the next workstation, meeting the needs of timed and quantitative control of parts feeding when producing certain special products. The parts quantitative feeding assembly includes a base 14, a rotary feeding assembly 12 movably coupled to the base 14, and a quantitative retention device 13 used in conjunction with the rotary feeding assembly 12.

[0042] The rotary feeding assembly 12 has a material receiving cavity 120 and a feeding port 121, the feeding port 121 facing the conveyor belt 11 and communicating the material receiving cavity 120 with the outside. The rotary feeding assembly 12 is rotatably coupled to the base 14. The rotary feeding assembly 12 can rotate and switch between a first position and a feeding position at a set angle to the first position. When the rotary feeding assembly 12 is in the feeding position, the parts in the material receiving cavity 120 of the rotary feeding assembly 12 can flow out from the feeding port 121. When the rotary feeding assembly 12 is in the first position, the parts in the material receiving cavity 120 of the rotary feeding assembly 12 cannot flow out from the feeding port 121. In a preferred embodiment, the first position is a horizontal position, and the tilt angle of the feeding position relative to the first position can be adjusted according to the actual situation. In a preferred embodiment of this application, when the rotating feeding component 12 is located at the feeding position, the parts contained in the material cavity 120 can slide out from the feeding port 121 by their own gravity.

[0043] The base 14 includes a base plate 141 and wings 142 extending upward from both sides of the base plate 141. The rotary feeding assembly 12 is rotatably coupled to the wings 142 on both sides of the feeding port 121. In a preferred embodiment, each wing 142 has a through mounting hole 1421. A rotating shaft 122 passes through one of the mounting holes 1421 and is inserted and fixed to the outer side of the rotary feeding assembly 12 at the feeding port 121. The other end of the rotating shaft 122 protrudes outward from the outer surface of the wing 142. A gear 123 is correspondingly sleeved and coupled to the end of the rotating shaft 122 located on the outer surface of the corresponding wing 142. The rotary feeding assembly 12 is driven to rotate by a linear actuator 125. Specifically, the linear actuator 125 is located outside the wing 142 of the rotating shaft 122. A drive rack 124 is fixed at the output end of the linear actuator 125, and the drive rack 124 meshes with the gear 123. The drive rack 124 serves as a transmission element for the linear actuator 125 to drive the rotary feeding assembly 12 to rotate. Of course, the end of the rotary feeding assembly 12 away from the rotating shaft 122 along the rotation axis is rotatably engaged with the corresponding wing 142 via a pin 1221. Specifically, the pin 1221 passes through the wing 142 at the end away from the rotating shaft 122 along the rotation axis of the rotary feeding assembly 12 and is inserted into the outer side of the corresponding rotary feeding assembly 12.

[0044] Please refer to the reference. Figure 2 and Figure 3 As shown, a rotation stop block 126 is fixedly provided at one end of the rotating shaft portion 122 and adjacent to the gear portion 123. A first stop block 127 is fixedly provided on the upper edge of the wing portion 142 on the side where the rotating shaft portion 122 of the part quantitative feeding assembly is located, and a second stop block 128 is fixedly provided on one side edge of the wing portion 142. When the rotating feeding assembly 12 rotates to the feeding position, the rotation stop block 126 stops at the first stop block 127; when the rotating feeding assembly 12 rotates to the first position, the rotation stop block 126 stops at the second stop block 128. By rotating the stop block 126 in conjunction with the first stop block 127 and the second stop block 128, the set rotation angle of the rotating feeding component 12 can be precisely controlled. When it is necessary to change the feeding position of the rotating feeding component 12, it can be easily achieved by simply adjusting the relative position of the first stop block 127 and the second stop block 128 or by replacing the rotating stop block 126 with a different shape.

[0045] Please refer to the reference. Figures 1 to 7As shown, the quantitative retention device 13 is positioned at the feeding port 121 of the rotary feeding assembly 12. The quantitative retention device 13 forms a retention chamber 131, which is preferably inclined and includes a discharge port 1312 and an inlet port 1311 facing the feeding port 121. The discharge port 1312 faces the conveyor belt 11, and the inlet port 1311 is higher than the discharge port 1312. The inlet port 1311 is correspondingly connected to the feeding port 121. An opening / closing member 132 is positioned at the discharge port 1312 for opening or closing the discharge port 1312. The opening / closing member 132 can be designed as a gate-like structure and its movement can be controlled by a cylinder or linear motor. Preferably, the inclination angle of the retention chamber 131 is the same as the inclination angle of the rotary feeding assembly 12 at the feeding position.

[0046] Please refer to the reference. Figure 2 and Figure 3 As shown, the rotary feeding assembly 12 is generally fan-shaped, including a top plate 1201 and a bottom plate 1202 spaced apart from each other, and a side portion 1203 connecting the sides of the top plate 1201 and the bottom plate 1202. The feeding port 121 is located at one end of the fan-shaped rotary feeding assembly 12 near the central angle. The rotary feeding assembly 12 also has a feeding port 129 that connects the material receiving cavity 120 to the outside, and the feeding port 129 is located at one end of the fan-shaped rotary feeding assembly 12 away from the central angle. The spacing between the top plate 1201 and the bottom plate 1202 is preferably designed to be slightly larger than the height of a single part. Preferably, the central angle of the fan-shaped rotary feeding assembly 12 is not greater than 120 degrees and not less than 30 degrees. This facilitates the smooth flow of parts. Through the design scheme of this application, automatic feeding of parts at timed and quantitative intervals can be achieved.
