[0033] The present utility model will be further described below with reference to the drawings and embodiments:

[0034] Embodiment 1: Refer to Figure 1-2 , a SMT patch production automatic feeder, which includes a frame 1, a component conveying groove 2, a conveyor belt 3, a top cylinder 4, a top block 5 and a driving mechanism; the component conveying groove 2 is fixed on the frame 1, and the upper flat section 3-1 of the conveyor belt 3 is located at the inner bottom side of the component conveying groove 2;

[0035] See also Figure 1-2 , wherein the driving mechanism is used to drive the conveyor belt 3 to move. In this embodiment, the driving mechanism includes a driving wheel 6-1, a driven wheel 6-2 and a motor 6-3; the driving wheel 6-1 and the driven wheel 6-2 are rotatably mounted on the frame 1 and are horizontally located on both sides of the component conveying trough 2; the conveyor belt 3 is wound around the driving wheel 6-1 and the driven wheel 6-2, and the motor 6-3 is used to drive the driving wheel 6-1 to rotate. During operation, the motor 6-3 drives the driving wheel 6-1 to rotate, and the driving wheel 6-1 drives the conveyor belt 3 to move around the driving wheel 6-1 and the driven wheel 6-2, and the upper flat section 3-1 of the conveyor belt 3 is used to convey the components N placed in the component conveying trough 2.

[0036] See also Figure 3-4 In addition, the front end of the element conveying trough 2 is provided with two side openings 2-1, and the two side openings 2-1 are respectively located on both sides of the upper flat section 3-1 of the conveyor belt 3; a baffle 7 is fixed in front of the element conveying trough 2; two inner step plates 5-1 are provided on the top block 5; the output end of the top cylinder 4 faces upward and is fixedly connected to the top block 5 (see Figure 9-11 ).

[0037] See also Figure 13-15 When the top block 5 drives the top block 5 upward, the two inner step plates 5-1 move upward in the two side openings 2-1 respectively and can lift up the component N blocked by the baffle 7 in the component conveying groove 2.

[0038] In this embodiment, a notch 7 - 1 is provided on the baffle 7 to facilitate the clamping claws of the robot to pass through and clamp a lifted component N when clamping.

[0039] When the present embodiment is working, a row of components N is pre-stored or the components are placed (or replenished) in the component conveying slot 2 while being conveyed.

[0040] The components N in the component conveying trough 2 are driven forward by the upper flat section 3-1 of the conveyor belt 3, and the frontmost component N will be blocked by the baffle 7 and reach the fixed point position; then the top cylinder 4 is started to work and drive the top block 5 upward, and its two inner step plates 5-1 respectively move upward in the two side openings 2-1 and can lift up the frontmost component N blocked by the baffle 7 in the component conveying trough 2. At this time, the frontmost component N is located above the front end of the component conveying trough 2 and is precisely positioned for the robot to grab at a fixed point. After the robot grabs it, the top cylinder 4 is started again to work and drive the top block 5 downward, so that the two inner step plates 5-1 respectively move downward in the two side openings 2-1 and return to their original positions, and the work is repeated.

[0041] Since the component N is guided and constrained within the component conveying groove 2 during conveyance (see Figure 8 ), this ensures that the position of the component N is accurately fixed when blocked by the baffle 7 (see Figure 9-11 ). Since there are two inner stepped plates 5-1 provided on the top block 5, when the top block 5 jacks up the component N, the component will be limited and clamped by the two inner stepped plates 5-1 (see Figure 13-15 ), and the component N will not exhibit phenomena such as displacement or tipping over, being very accurate, stable, and reliable.

[0042] Preferably, see Figure 3-4 , a conveyor belt guiding groove 2-21 is provided in the middle of the inner bottom of the component conveying groove 2; two pin avoiding grooves 2-22 are respectively provided on both sides of the inner bottom of the component conveying groove 2; the upper flat section 3-1 of the conveyor belt 3 is located within the conveyor belt guiding groove 2-21. The upper flat section 3-1 moves in a guided manner within the conveyor belt guiding groove 2-2 (see Figure 8 ), which can reduce the lateral swing of the upper flat section 3-1, ensure accurate and stable conveyance, and meet the high requirements for precision conveyance of extremely small components. At the same time, the two pins N-1 of the component N respectively extend into the two pin avoiding grooves 2-22 to avoid interference and prevent tipping over.

[0043] Preferably, the top cylinder 4 is a telescopic cylinder.

[0044] In this embodiment, see Figure 5-6 , the inner side of the inner stepped plate 5-1 successively has an upper vertical surface 5-11, an upper stepped plane 5-12, a middle vertical surface 5-13, a lower stepped plane 5-14, and a lower vertical surface 5-15 from top to bottom.

[0045] In this embodiment, the main body of the component N is a cube, and two pins N-1 are provided below the component N. When jacked up, the upper vertical surface 5-11, the upper stepped plane 5-12, the middle vertical surface 5-13, the lower stepped plane 5-14, and the lower vertical surface 5-15 of the two inner stepped plates 5-1 can limit and clamp the component N when cooperating with the component N. Among them, the upper vertical surfaces 5-11 of the two inner stepped plates 5-1 cooperate with the two side surfaces of the component N for limiting, the upper stepped planes 5-12 of the two inner stepped plates 5-1 horizontally support both sides of the bottom surface of the component N, the lower stepped planes 5-14 of the two inner stepped plates 5-1 respectively horizontally support the two pins N-1. At this time, the component can always maintain an accurate and stable posture within the two inner stepped plates 5-1, and ensure that there will be no displacement or tipping over phenomena during the jacking movement and when being clamped by the manipulator (see Figure 11 and Figure 14-15 ).

[0046] In summary, this embodiment can solve the technical problem of how to convey electrical components to a fixed position and then lift a single workpiece for precise grasping by a manipulator at a fixed point. At the same time, when the components are conveyed to the fixed point and lifted, the technical requirements of precision, stability, and reliability are met, and there should be no displacement or tipping phenomenon.

[0047] Embodiment 2: This embodiment is a further improvement based on Embodiment 1:

[0048] Refer to Figure 16 , further, there are two component conveying grooves 2 which are arranged side by side and parallel. In this way, this embodiment can be used for the conveying of two groups of components (which can be the same or different) at the same time.

[0049] Specifically, each of the component conveying grooves 2 is correspondingly provided with a set of conveyor belt 3, a jack 4, a top block 5, and a driving mechanism.

[0050] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
