[0020] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0021] This specific embodiment describes in detail the O-ring material taking mechanism described in this application. Figure 1-Figure 5As shown, the O-ring material taking mechanism includes: a fixed plate 1, a first linear motion mechanism 2, a second linear motion mechanism 3, a sleeve 4 and a pin 5, the O-ring 11 is made of elastic material, the first linear motion mechanism 2 is fixed to the front of the fixed plate 1, and a fixed seat is protruding from the front of the fixed plate 1, and the fixed seat is located below the first linear motion mechanism 2, the sleeve 4 is hollow and tubular, and the sleeve 4 is slidably connected to the fixed seat, the top end of the pin 5 is connected to the moving end of the first linear motion mechanism 2, and the bottom end of the pin 5 is slidably penetrated by the sleeve 4, the second linear motion mechanism 3 is fixed to the back of the fixed plate 1, and the second linear motion mechanism 3 is fixed to the back of the fixed plate 1. The moving end of the linear motion mechanism 3 is connected to the sleeve 4, and at least two material-picking petals 6 extend downward from the bottom end of the pin 5. The material-picking petals 6 are arranged at circumferential intervals around the pin 5. The pin 5 can move downward under the drive of the first linear motion mechanism 2, and the material-picking petal 6 can extend from the bottom end of the sleeve 4 and extend into the inner ring of the O-ring 11. The outer peripheral wall of the material-picking petal 6 can be tightly attached to the inner ring of the O-ring 11 and fix the O-ring 11. The sleeve 4 can move downward under the drive of the second linear motion mechanism 3, and the bottom end of the sleeve 4 can squeeze the top surface of the O-ring 11 and push the O-ring 11 away from the material-picking petal 6. When in use, the fixed plate 1 is fixed to a moving mechanism, such as the moving end of a gantry mechanism or the moving end of a robotic arm. The gantry mechanism and the robotic arm are prior art and will not be described in detail in this embodiment. The O-ring 11 is placed flat on the material picking platform. The O-ring picking mechanism is driven by the moving mechanism to move to the material picking platform and ensure that the picking petal 6 is located directly above the O-ring 11. The pin 5 moves downward under the drive of the first linear moving mechanism 2. At this time, the picking petal 6 extends into the inner ring of the O-ring 11. At the same time, the outer peripheral wall of the picking petal 6 is tightly against the inner ring of the O-ring 11, fixing the O-ring 11 by friction. When the O-ring 11 needs to be removed, the O-ring picking mechanism is driven by the moving mechanism to move to the unloading position. The sleeve 4 moves downward under the drive of the second linear moving mechanism 3. The bottom end of the sleeve 4 squeezes the top surface of the O-ring 11 to make the O-ring 11 separate from the picking petal 6. Then the first linear moving mechanism 2 and the second linear moving mechanism 3 are reset. This process is repeated to achieve automatic grabbing of the O-ring 11. It has the advantage of high degree of automation.

[0022] In this embodiment, the outer wall of the material extraction flap 6 is optionally provided with a groove into which the inner ring of the O-ring 11 can be inserted. The bottom end of the material extraction flap 6 is provided with a chamfer, and a slope is provided in the groove on one side near the bottom end of the material extraction flap 6. The chamfer facilitates the insertion of the material extraction flap 6 into the inner ring of the O-ring 11, and the slope facilitates the removal of the O-ring 11 from the groove.

[0023] Optionally, this embodiment further includes a connecting member 7, a notch for the connecting member 7 to be inserted into the middle of the fixing seat, and the connecting member 7 is detachably fixed to the fixing plate 1 by bolts. A connecting hole is provided through the connecting member 7, and a linear bearing is provided in the connecting hole. The outer peripheral wall of the sleeve 4 is slidably connected to the linear bearing, and the bottom end of the sleeve 4 can extend out of the connecting hole.

[0024] Optionally, this embodiment further includes a connecting plate 8, the first linear motion mechanism 2 is a first cylinder, the cylinder rod of the first cylinder is the moving end of the first linear motion mechanism 2, the second linear motion mechanism 3 is a second cylinder, the cylinder rod of the second cylinder is the moving end of the second linear motion mechanism 3, the first end of the connecting plate 8 is fixed to the cylinder rod of the second cylinder, and the second end of the connecting plate 8 is fixed to the outer peripheral wall of the bottom end of the sleeve 4.

[0025] In this embodiment, the pick-up flaps 6 can optionally be provided with arc-shaped notches on the facing sides, so that the outer peripheral wall of the workpiece on which the O-ring 11 is to be fitted can be inserted into the arc-shaped notches of the pick-up flaps 6. In this embodiment, the workpiece can be inserted into the gap between the pick-up flaps 6, and the outer peripheral wall of the workpiece fits neatly into the arc-shaped notches. After the workpiece is inserted into the gap between the pick-up flaps 6, the second linear motion mechanism 3 drives the sleeve 4 downward and pushes the O-ring 11 out of the pick-up flaps 6. At this time, the O-ring 11 can be fitted neatly onto the workpiece. In this way, the pick-up flaps 6 can not only capture the O-ring 11, but also assist in the installation of the O-ring 11, thus achieving multiple uses for one component.

[0026] This embodiment optionally further includes two positioning pins 9. The fixing base has two positioning holes formed therein. The positioning holes extend through the upper and lower surfaces of the fixing base, with one positioning pin 9 corresponding to each positioning hole. The positioning pin 9 can be inserted into the positioning hole and secured by a screw. A limit block 10 is provided at the top of the positioning pin 9, and the bottom of the positioning pin 9 can pass through the positioning hole. The positioning pin 9 can serve as a positioning device. Positioning holes that can cooperate with the positioning pins 9 are provided on the material retrieving platform and the material unloading position to improve the accuracy of material retrieving and unloading.

[0027] Optionally, in this embodiment, the top end of the slope is connected to the outer peripheral wall of the material removal flap 6, and the bottom end of the slope is connected to the bottom wall of the groove.

[0028] In this embodiment, the material removal flap 6 is optionally made of an antistatic material. Setting the material removal flap 6 to be an antistatic material can prevent the O-ring 11 from being adsorbed by static electricity and causing the O-ring 11 to be unable to separate from the material removal flap 6.

[0029] The use of the O-ring material taking mechanism in this embodiment has the advantage of a high degree of automation.
