Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an automatic alternating feeding mechanism. Background Technology
[0002] Non-standard automated equipment is defined as user-customized, unique, and non-market-circulated automated system integration equipment. It is assembled from unit equipment manufactured in accordance with national unified industry standards and specifications, and is developed, designed, and manufactured according to the customer's needs.
[0003] In a non-standard automated equipment for batch gluing of ring-shaped workpieces, the number of ring-shaped workpieces requiring gluing is very large due to the mass production of these workpieces. However, such equipment typically only automates the gluing process; the automatic unloading, conveying, and collection of the glued ring-shaped workpieces still requires manual operation, necessitating further improvements to enhance production efficiency.
[0004] In existing technologies, the automatic unloading of ring-shaped workpieces mostly uses a robotic arm to drive an independent centering mechanism for clamping. However, this method makes it difficult to ensure the controllability of the pressure exerted on the ring-shaped parts during gripping. Excessive force can cause deformation of the ring-shaped parts, while insufficient force can cause them to fall off, affecting the stability of the workpiece. In addition, unloading with a robotic arm requires extremely high precision in the coordination between the robotic arms. Misalignment can damage the workpiece. Furthermore, since these ring-shaped workpieces require adhesive to be applied to their outer wall, misalignment in this clamping method can cause the grippers to hold the adhesive application area, affecting the adhesive application effect. Additionally, due to the adhesive's stickiness, if it adheres to the grippers, the ring-shaped workpiece will be unable to detach from the grippers when they are released, thus preventing unloading from being completed.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0027] Reference Figure 1-3 As shown, the automatic alternating unloading mechanism of this utility model includes: a dual-axis moving slide 1, on which a tray 2 for placing workpieces is provided; an unloading support frame 3; an unloading drive cylinder 4, which is mounted on the unloading support frame 3; an unloading drive slider 5, which is connected to the output end of the unloading drive cylinder 4, and push block 6 and push block 7 are connected to the unloading drive slider 5; and two symmetrically arranged grippers 8, which are used to receive workpieces when closed, and the unloading drive cylinder 4 drives the two grippers 8 to open. The workpiece is passed through and unloaded into the tray 2; there are two symmetrically arranged grippers 9, which are used to receive the workpiece when closed. The unloading drive cylinder 4 drives the two grippers 9 to open so that the workpiece can pass through and be unloaded into the tray 2. The opening and closing action of the two grippers 9 is opposite to that of the two grippers 8; the unloading guide rod 10 has its initial end located on the side where the workpiece is unloaded, and the end of the unloading guide rod 10 passes through the gap between the two grippers 8 and the two grippers 9.
[0028] Reference Figure 4 , 5As shown, the push block 6 is located between the two grippers 8, and the middle position of the push block 6 is set as a trapezoidal part 61, with the larger end of the trapezoidal part 61 being closer to the unloading drive cylinder 4. The push block 7 is located between the two grippers 9, and the middle position of the push block 7 is set as a trapezoidal part 71, with the larger end of the trapezoidal part 71 being away from the unloading drive cylinder 4. The direction of the waist inclination of the trapezoidal part 71 is opposite to the direction of the waist inclination of the trapezoidal part 61. In this way, when the unloading drive cylinder 4 drives the unloading drive slider 5 to move linearly, the push blocks 6 and 7 have opposite effects on the two grippers 8 and the two grippers 9. When the two grippers 8 open, the two grippers 9 close, so that the two grippers 8 and the two grippers 9 sequentially catch the falling annular workpiece.
[0029] In the above structure, the first gripper 8 is equipped with a roller 81, which is rolledly connected to the side wall of the first gripper 8. The roller 81 rolls along the waist of the trapezoidal portion 61 to open or close the two grippers 8. The roller 81 is always in contact with the side wall of the first gripper 8. When the unloading drive cylinder 4 drives the unloading drive slider 5 to move, the push block 6 and the second push block 7 move synchronously. During the process of the waist of the trapezoidal portion 61 contacting the roller 81, due to the inclined setting of the waist of the trapezoidal portion 61, the two grippers 8 are driven to open or close. The second gripper 9 is equipped with a roller 91, which is rolledly connected to the side wall of the second gripper 9. The roller 91 rolls along the waist of the second trapezoidal portion 71 to open or close the two grippers 9. The operating principle of the two grippers 2 9 is the same as that of the two grippers 1 8, except that the opening and closing actions of the two grippers 2 9 are opposite to those of the two grippers 1 8.
[0030] A first elastic reset element is provided between the two jaws 8 to close the two jaws 8. A second elastic reset element is provided between the two jaws 9 to close the two jaws 9. The first and second elastic reset elements are preferably springs. After the two jaws 8 or the two jaws 9 are opened, the first and second elastic reset elements respectively close the jaws, so that when the annular workpiece falls again, it lands on the closed jaws 8 or the two jaws 9.
[0031] In the above structure, the unloading support frame 3 is provided with a horizontal support plate 31, and the horizontal support plate 31 is provided with a linear guide rail 32. The unloading drive slider 5 is connected to a slider 51, which is mounted on the linear guide rail 32 and can slide along the linear guide rail 32. The linear guide rail 32 is arranged along the direction in which the piston rod of the unloading drive cylinder 4 extends or retracts. The horizontal support plate 31 is provided with a linear guide rail 33 and a linear guide rail 34. The gripper 8 is connected to a slider 82, and the gripper 9 is connected to a slider 92. The slider 82 is slidably mounted on the linear guide rail 33, and the slider 92 is slidably mounted on the linear guide rail 34.
[0032] Reference Figure 6 As shown, the unloading guide rod 10 includes a guiding part 101 and an unloading part 102, both of which are cylindrical rods. The guiding part 101 is inclined, with its upper end located on the side where the workpiece is unloaded. The unloading part 102 is vertically arranged, and its upper end is connected to the lower end of the guiding part 101. The unloading part 102 is located between the gaps between the two grippers 9 and the two grippers 8. The diameter of the unloading part 102 is larger than the diameter of the guiding part 101. The upper end of both the guiding part 101 and the unloading part 102 are tapered.
[0033] In the above structure, the tray 2 is a rectangular tray, and a plurality of workpiece positioning posts 21 are provided on the bottom surface inside the tray 2. Preferably, the plurality of workpiece positioning posts 21 are arranged in a circular array. The upper end of the workpiece positioning post 21 is set as a cone. The unloading part 102 is suspended above the workpiece positioning post 21. The annular workpiece received by the guide part 101 slides down the guide part 101 onto the unloading part 102. After passing through the gap between the two grippers 8 and the two grippers 9, the annular workpiece is fitted onto the workpiece positioning post 21, thereby forming the workpiece neatly arranged in the tray 2.
[0034] The inner walls of the two opposing jaws 8 are provided with arc-shaped grooves 83, and the inner walls of the two opposing jaws 9 are provided with arc-shaped grooves 93. The two jaws 8 are located directly above the two jaws 9, so that the cylindrical part of the unloading part 102 passes through the two jaws 8 and the two jaws 9. When the two jaws 8 clamp the unloading part 102, the unloading part 102 is exactly within the range enclosed by the two arc-shaped grooves 83, and the workpiece falls on the two jaws 8. At this time, the two jaws 9 open. When the release unloading section 102 is opened, the two grippers 29 close and hold the unloading section 102. The workpiece falls along the unloading section 102 and lands on the two grippers 29. Then, the two grippers 18 close and hold the unloading section 102. The two grippers 29 open, and the workpiece that originally landed on the two grippers 29 falls along the unloading section 102 under the action of gravity and is placed on the workpiece positioning post 21. The above process is repeated continuously, so that one ring-shaped workpiece after another falls into the tray 2 through the two grippers 18 and the two grippers 29.
[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
