[0017] Referring to Figures 1 to 4 The utility model provides a kind of buffer device for reducing robot's plate force, comprising: base 1, the two ends of the upper surface of the base 1 are symmetrically connected with limiting plate 6, and the middle part of the upper surface of the base 1 is provided with a receiving groove, buffer grooves 7 are symmetrically provided on both sides of the receiving groove, the bottom of the buffer groove 7 is fixedly connected with guide rod 2, the surface of the guide rod 2 is sleeved with auxiliary spring, and the receiving groove is respectively fixedly connected with buffer air bag 14, fixed cylinder 8 and positioning cylinder 12, the inner side of the fixed cylinder 8 is fixedly connected with friction layer 10, the upper surface of the positioning cylinder 12 is symmetrically connected with limiting rod 13, and the lower end of the fixed rod 9 is slidably connected in the inner cavity of the friction layer 10, the upper end of the fixed rod 9 is fixedly connected with the lower surface of object plate 5, the lower surface of the object plate 5 is symmetrically connected with shielding plate 4, the lower surface of the shielding plate 4 is connected with buffer block 3 corresponding to the position of the buffer groove 7, the buffer block 3 is sleeved with guide rod 2 through through hole, and the lower surface of the object plate 5 is connected with buffer column 11 corresponding to the position of the inner cavity of the positioning cylinder 12, and the surface of the buffer column 11 is sleeved with main spring on the upper end.
[0018] In the embodiment, when the heavy or large number of plates need to be carried and placed, the workers usually use robots (not shown in the figure) to assist in carrying and placing. After the base 1 and the loading plate 5 are moved to the appropriate position by the brake wheel, the workers place the plates on the upper surface of the loading plate 5 through the robot. The plates will first contact the buffer layer on the upper surface of the loading plate 5 when placed, which can preliminarily buffer the force of the robot when placing the plates, and can also avoid the problem of direct contact between the plates and the loading plate 5, thereby reducing the probability of accidental damage of the plates due to the large placing force of the robot. In addition, the plates will further weaken the force of the robot when placing the plates by pushing the loading plate 5 downward through the buffer layer, so that the stress on the surface of the loading plate 5 is gradually increased, thereby reducing the probability of accidental damage of the plates due to the instantaneous excessive stress. During the downward movement of the loading plate 5, the loading plate 5 will synchronously move downward with the fixedly connected buffer column 11, the shielding plate 4, the buffer block 3 and the fixed rod 9. The buffer column 11 will move relative to the positioning cylinder 12, and then the main spring sleeved with the buffer column 11 will be squeezed between the loading plate 5 and the positioning cylinder 12. The buffer block 3 will synchronously squeeze the auxiliary spring sleeved with the guide rod 2 during the downward movement of the buffer block 3 along the guide rod 2. The buffer air bag 14 arranged in the receiving groove will also be synchronously squeezed and deformed, thereby assisting to enhance the buffering and weakening effect of the device on the force of the robot when placing the plates. In addition, the fixed rod 9 can effectively enhance the friction resistance of the loading plate 5 during the embedding process of the fixed rod 9 in the friction layer 10, thereby effectively enhancing the stability of the loading plate 5 after moving, avoiding the continuous up-and-down vibration of the loading plate 5 with the plates, and ensuring the stability of the plates when placed.
