Abstract
Description
Technical Field
[0001] This application relates to the technical field of glass grasping and handling, in particular to a sucker leg lifting mechanism. Background Art
[0002] The sucker leg lifting mechanism of the traditional sucker rack is a horizontal linear motion, and the sucker leg is lifted by the linear motion of the cylinder directly pushing the sucker to act. The traditional structure has defects: 1. Since the specifications of glass products are constantly updated, the posture of the robotic arm grasping the glass will change continuously, so it is required to reduce the thickness of the entire sucker rack to avoid interference with the trajectory of the robotic arm. 2. The position of the sucker leg installed on the sucker rack cannot be restricted, resulting in the inability to form a sealed vacuum for the glass at the extreme position of grasping, causing the glass to fall and being unsightly.

[0006] Preferably, in the above-mentioned sucker leg lifting mechanism, a nut is threadedly connected to the lifting rod above the annular step, and the bottom end of the spring abuts against the upper end surface of the nut.
[0007] Preferably, in the above-mentioned sucker leg lifting mechanism, there are a pair of swing arms, and the pair of swing arms are symmetrically arranged on both sides of the telescopic cylinder.
[0008] Preferably, in the above-mentioned sucker leg lifting mechanism, the telescopic cylinder is horizontally arranged.
[0009] Compared with the prior art, the advantages of the present utility model are as follows:
[0010] The cylinder drives the swing arm to swing, so that the extension part abuts against the step, causing the lifting rod to move up and down, changing the horizontal movement of lifting the sucker leg into a vertical movement, greatly reducing the thickness of the entire structure, eliminating the interference hidden danger of the robotic arm path, improving the structure, enhancing the rationality of grasping, and improving the appearance. Brief Description of the Drawings
[0011] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings described below are only some embodiments recorded in the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0014] The following will combine the drawings in the embodiments of the present utility model to describe the technical solutions in the embodiments of the present utility model in detail. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0015] Refer Figures 1-2 As shown, the sucker leg lifting mechanism in this embodiment includes a mounting plate 1. A sucker 2 is provided below the mounting plate 1. A lifting rod 3 is fixed to the top of the sucker 2. The top of the lifting rod 3 penetrates through the mounting plate 1 and extends above the mounting plate 1. A pair of annular blocks 4 are fixedly sleeved on the lifting rod 3 above the mounting plate 1 up and down. A telescopic cylinder 5 is provided on one side of the lifting rod 3. The telescopic cylinder 5 is hinged to the mounting plate 1. The output end of the telescopic cylinder 5 is hinged to a swing arm 6. The top of the swing arm 6 is hinged to the mounting plate 1. An extension part 7 protrudes from the end of the swing arm 6 facing the lifting rod 3. The extension part 7 extends between the pair of annular blocks 4. An annular step 8 is provided on the lifting rod 3 below the mounting plate 1. A spring 9 is provided between the annular step 8 and the mounting plate 1. The spring 9 is sleeved on the lifting rod 3.
[0016] Furthermore, a nut 10 is threadedly connected to the lifting rod 3 above the annular step 8. The bottom end of the spring 9 abuts against the upper end surface of the nut 10. The nut can be used to adjust the tightness of the spring, with better flexibility.
