Description

Technical Field

[0001] The utility model relates to the technical field of piece-picking machines, in particular to a vertical multi-link piece-picking machine. Background Art

[0002] The use of a retrieval machine can effectively improve the production efficiency of die-casting production lines, reduce labor costs, and enhance product quality. First, the retrieval machine enables high-speed, continuous, and accurate retrieval, significantly reducing the time and error associated with manual operations. Second, the automatic retrieval machine ensures consistent and accurate retrieval, eliminating the impact of human factors on product quality. Furthermore, the automatic retrieval machine automates production, reducing the environmental impact of manual operations.

[0003] However, existing automatic retrieval machines still have some problems. For example, after removing a die-cast part, existing retrieval machines typically rotate a rotating arm and release a mechanical claw. When the claw is released, the die-cast part automatically falls. The inventor believes that in actual production processes, to ensure production continuity, a belt conveyor is often used to receive the die-cast part released from the retrieval machine. If the drop height is relatively high, the die-cast part and the belt conveyor may collide violently, causing damage to both the die-cast part and the belt conveyor. Therefore, it is urgent to develop a retrieval machine that can effectively solve these problems. Utility Model Content

[0006] Preferably, the material receiving trough is open at one end away from the mechanical claw, and the height of the material receiving trough at the end away from the mechanical claw is lower than the height of the end close to the mechanical claw.

[0009] Preferably, a buffer deceleration mechanism is provided at one end of the material receiving trough away from the mechanical claw, and the buffer deceleration mechanism includes a fixed block and a curtain fixed under the fixed block.

[0011] Compared with the prior art, the present invention has the following advantages: a multi-link material receiving mechanism is added to the prior art piece-picking machine; through the setting of the multi-link material receiving mechanism, when the mechanical claw unloads the material, the die-casting can roll downward through the material receiving trough, consuming part of the energy during the rolling process; and the material receiving trough is designed with two parallel connecting rods, so that when the die-casting rolls downward through the material receiving trough, the material receiving trough can automatically swing downward to lower the height, thereby reducing the distance between the material receiving trough and the belt conveyor, preventing the die-casting from colliding violently with the belt conveyor, and solving the problem in the prior art that the die-casting falls directly from a high place onto the belt conveyor and suffers a violent impact when the piece-picking machine unloads the material.

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0014] Figure 2 This is a schematic diagram of the structure of the buffer deceleration mechanism of the utility model. DETAILED DESCRIPTION

[0015] The following is combined with Figure 1-2 The specific implementation methods of the present utility model are further described in detail.

[0016] Depend on Figure 1-2The utility model provides a vertical multi-link piece-picking machine, comprising a base 10, a telescopic cylinder 30 fixed to the upper end of the base 10, a rotating arm 40 rotatably mounted at the front end of the telescopic cylinder 30, and a mechanical claw 50 mounted at the front end of the rotating arm 40 for clamping the die-casting 20. When in use, the telescopic cylinder 30 extends to drive the mechanical claw 50 to move to the die-casting station, and the die-casting 20 is grabbed by the mechanical claw 50. Then, the telescopic cylinder 30 shortens to bring the die-casting 20 out through the mechanical claw 50, and then the rotating arm 40 rotates to release the mechanical claw 50 to drop the die-casting 20. The above structure is a common existing piece-picking machine structure, so it is not described in detail in this embodiment. The key improvements of this embodiment are:

[0017] The base 10 is provided with a multi-link material receiving mechanism 60, which includes a material receiving trough 61 arranged on the side of the rotating arm 40 for receiving the die-casting 20, a sliding seat 62 vertically slidably mounted on the side of the base 10, two parallel connecting rods 63 rotatably connected between the material receiving trough 61 and the sliding seat 62, and a motor 64 fixed to the sliding seat 62 for driving one of the parallel connecting rods 63 to rotate, the material receiving trough 61 is open at one end away from the mechanical claw 50, and the height of the material receiving trough 61 at the end away from the mechanical claw 50 is lower than that at the end close to the mechanical claw 50. The height of the end is determined by the setting of the material receiving trough 61. When the die-casting 20 is put down, the mechanical claw 50 is driven to rotate by the rotation of the rotating arm 40. Then, when the mechanical claw 50 releases the die-casting 20, the die-casting 20 will fall into the material receiving trough 61. Under the action of gravity, the die-casting 20 will slide from the lower end. During the sliding process, its gravitational potential energy is converted into kinetic energy and thermal energy. Moreover, during the sliding process, the connecting rod 63 is driven to rotate counterclockwise by the motor 64, which can lower the height of the material receiving trough 61, thereby reducing the distance between the material receiving trough 61 and the belt conveyor, and preventing the die-casting 20 from colliding violently with the belt conveyor.

[0018] Furthermore, the sliding base 62 includes a sliding base 621 and a rotating base 622. The sliding base 621 is vertically movably connected to the base 10. The rotating base 622 is rotatably connected to the parallel connecting rod 63. The motor 64 is fixedly installed on the rotating base 622. One end of the rotating base 622 is rotatably connected to one end of the sliding base 621. The other end of the rotating base 622 is connected to the other end of the sliding base 621 with an adjusting cylinder 623. The two ends of the adjusting cylinder 623 are rotatably connected to the sliding base 621 and the rotating base 622 respectively. The sliding base 621 can slide in the height direction of the base 10 to adjust the height of the material receiving trough 61. When the adjusting cylinder 623 is extended or retracted, it can drive the rotating base 622 to rotate, thereby adjusting the inclination degree of the material receiving trough 61.

[0019] Specifically, two screws 65 are fixed to the lower end of the sliding base 621, and a mounting plate 11 is fixed to the side of the base 10. The screws 65 pass through the mounting plate 11 and are threadedly connected to fixing bolts 66. The height of the sliding base 621 can be adjusted by the movement of the screws 65 in the mounting plate 11.

[0020] In some embodiments, a buffer deceleration mechanism 70 is provided at one end of the material receiving trough 61 away from the mechanical claw 50. The buffer deceleration mechanism 70 includes a fixed block 71 and a curtain 72 fixed under the fixed block 71. Installation grooves 610 are provided on both sides of the inner wall of the material receiving trough 61. The fixed block 77 is slidably installed in the installation groove 610 and fixed by a locking bolt 611. The fixed block 77 slides in the installation groove 610 to facilitate adjustment of the height of the curtain 72. By setting the curtain 72, the speed of the die-casting 20 can be reduced, thereby playing a buffering role.

[0021] The number of the buffer deceleration mechanisms 70 is at least two.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
