Description

Technical Field

[0001] This utility model belongs to the field of pickup machinery technology, and in particular relates to an alternating pickup device. Background Technology

[0002] In automated production lines, robotic arms are typically used to transfer and assemble parts, thereby replacing manual labor and improving production efficiency and quality.

[0003] Existing material handling robots typically use electric screws, cylinders, or cam mechanisms to drive the lifting components (e.g., pneumatic clamps, suction nozzles) to pick up and assemble parts. To improve efficiency, two or more picking devices are often used alternately. Specifically, the mechanism of two picking devices generally includes an electric screw lifting mechanism connected to a mounting plate. The mounting plate has multiple sets of lifting cylinders, each set connected to a picking component. First, the electric screw lifting mechanism drives the mounting plate to descend. Then, each set of lifting cylinders alternately rises and falls to pick up the parts.

[0004] However, the aforementioned alternating material handling device requires two sets of power-driven lifting mechanisms to achieve alternating material handling. Its structure is relatively more complex, and the use of cylinders for lifting introduces a problem: the cylinders exert a certain impact force, which could cause damage to the parts during material handling.

[0016] The alternating pickup device provided in this embodiment of the present invention has at least the following technical effects:

[0017] The motor drives the connecting plate to rotate, causing its two ends to alternately reach high and low points. This, in turn, drives two sets of connecting rods to move the corresponding lifting seats, as well as the connecting seats and pickup components, up and down.

Figures 1 to 4 The alternating pick-up device of this embodiment is used to be installed on a moving mechanism to pick up or assemble workpieces. Specifically, the alternating pick-up device of this embodiment includes a carrier plate 100, a motor 200, a connecting plate 400, a connecting rod 500, a lifting seat 600, a connecting seat 700, and a pick-up assembly 800. A motor seat 110 is provided on one side of the carrier plate 100, and the motor 200 is mounted on the motor seat 110. The motor 200 includes a main shaft, the connecting plate 400 is connected to the main shaft, and both ends of the connecting plate 400 are rotatably connected to the connecting rod 500. The bottom end of the connecting rod 500 is rotatably connected to the lifting seat 600, the lifting seat 600 is slidably connected to the carrier plate 100, the connecting seat 700 is connected to the lifting seat 600, and the pick-up assembly 700 is mounted on the connecting seat 700. Specifically, motor 200 drives connecting plate 400 to rotate, causing both ends of connecting plate 400 to alternately be at high and low points. This drives two sets of connecting rods 500 to move the corresponding lifting seats 600, as well as the connecting seats 700 and pickup components 800, up and down, thereby achieving the alternating up and down movement of the two pickup components 800 to achieve the function of alternating material picking. Therefore, one motor 200 can simultaneously drive two sets of pickup components 800 to alternately lift and pick up materials, resulting in a simple structure and low cost. Furthermore, the lifting speed of the pickup components 800 can be controlled by motor 200, which can avoid the problem of excessive impact force hitting the workpiece.

[0028] Furthermore, refer to Figures 1 to 3The picking component 800 includes a rotary motor 810 and a suction nozzle 820; a support portion 710 extends from the bottom side of the connecting seat 700, the rotary motor 810 is mounted on the support portion 710, and the suction nozzle 820 is mounted on the rotating shaft of the rotary motor 810. In this embodiment, the suction nozzle 820 can pick up the workpiece, and the rotary motor 810 drives the suction nozzle 820 to rotate, thereby rotating the workpiece and meeting the needs of material picking and assembly.

[0029] Furthermore, refer to Figure 3 The connecting rod 500 has connection positions at both ends, which connect to the connecting plate 400 and the lifting seat 600 respectively. Each connection position includes a bent portion 501 forming a connection hole; the free end of the bent portion 501 has a through hole 502, and the side wall of the connecting rod 600 has a screw hole 503; a bearing 510 is installed inside the connection hole, and a connecting shaft 511 is located at the center of the bearing 510; a locking screw passes through the through hole 502 and connects to the screw hole 503, causing the bent portion 501 to grip the bearing 510. In this embodiment, this facilitates the rotatable connection between the connecting rod 500 and the connecting plate 400 and the lifting seat 600.

[0030] Furthermore, refer to Figure 1 and Figure 3 The connecting seat 700 is slidably connected to the carrier plate 100. An adjusting plate 900 is also connected between the connecting seat 700 and the lifting seat 600. The adjusting plate 900 has grooves on its upper and lower sides, and locking screws pass through the corresponding grooves to connect with the connecting seat 700 and the lifting seat 600. Specifically, the adjusting plate 900 connects the lifting seat 600 and the connecting seat 700 as a single unit, enabling simultaneous lifting and lowering. Furthermore, the adjusting plate 900 can be used to adjust the distance between the connecting seat 700 and the lifting seat 600, thereby adjusting the lowest point of the pickup assembly 800.

[0031] Furthermore, refer to Figure 2 The back side of the carrier plate 100 is also provided with a mounting base 120, which is used to mount on the transverse mechanism. The motor base 110 is located on the front side of the carrier plate 100. In this embodiment, the transverse mechanism can be used to drive the overall translation, realizing automatic material picking and assembly. Furthermore, the motor base 110 and the mounting base 120 are located on both sides of the carrier plate 100, thereby ensuring that the assembly does not interfere with each other.

[0032] Furthermore, refer to Figure 2 The mounting base 120 is also provided with an adjusting base 130 on its bottom side. The adjusting base 130 is slidably connected to the mounting base 120. An adjusting screw 140 is also provided between the adjusting base 130 and the mounting base 120. The adjusting base 130 is connected to the transverse movement mechanism. The mounting base 120 is adjusted by adjusting the adjusting screw 140, thereby adjusting the front and rear position of the pickup component 800.

[0033] Furthermore, refer to Figure 4The motor mount 110 includes a connecting portion 111 and a downwardly extending mounting portion 112, with the connecting portion 111 and the mounting portion 112 forming an L-shape. A mounting groove is provided on the front side of the carrier plate 100, and the connecting portion 111 is positioned within the mounting groove; the motor 200 is located on one side of the mounting portion 112. This creates a mounting space between the mounting portion 112 and the carrier plate 110, into which the main shaft of the motor 200 extends, and the connecting rod 500 is also located, making the overall structure more compact.

[0034] Furthermore, refer to Figure 4 The motor base 110 has multiple recessed cavities in both its connecting portion 111 and mounting portion 112, with support plates 113 formed between these cavities. Each support plate 113 has a mesh-like perforated structure. Specifically, the motor base 110 can be formed using metal 3D printing. In this embodiment, the weight of the motor base 110 can be reduced while maintaining its strength, thereby reducing the overall weight and enabling rapid movement with low inertia.

[0035] Furthermore, refer to Figure 2 The main shaft of the motor 200 is equipped with a rotating baffle 210, and the inner side of the motor base 110 is equipped with a photoelectric switch 220 for detecting the position of the rotating baffle 210. This allows the position of the connecting plate 400 to be detected, thereby better controlling the lifting and lowering of the corresponding pickup component 800.

[0036] Furthermore, a camera 300 is also provided on the front side of the carrier plate 100 for positioning the workpiece to be picked up. This facilitates accurate workpiece picking and assembly.
