[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Figures 1 to 4The embodiment relates to an automatic loading device, which comprises a bottom plate 1, a needle 2 and a driving device 3, the driving device 3 drives the needle 2 to extend or retract from the surface of the bottom plate 1; when the driving device 3 drives the needle 2 to extend from the surface of the bottom plate 1, the front end of the needle 2 is inserted into a plastic part 10, so that the plastic part 10 is mounted on the bottom plate 1. The plastic part 10 is a sponge-like plastic part.

[0031] In a normal state, the driving device 3 does not work, at this time, the front end of the needle 2 is retracted below the surface of the bottom plate 1, so that the hand of a worker can be prevented from being pricked by the needle 2. When the plastic part 10 needs to be mounted on the surface of the bottom plate 1, the worker only needs to place the plastic part 10 on the surface of the bottom plate 1, and then the driving device 3 drives the needle 2 to extend from the surface of the bottom plate 1, so that the front end of the needle 2 is inserted into the plastic part 10, thereby mounting the plastic part 10 on the bottom plate 1, achieving the function and purpose of mounting the plastic part 10 on the bottom plate 1, and having the advantages of simple structure, convenient and fast use.

[0032] As shown in Figure 1 and Figure 5 , the needle 2 is provided with two groups, and the included angle between the front ends of the two groups of needles 2 is greater than zero degrees when the two groups of needles 2 extend from the surface of the bottom plate 1, so that the plastic part 10 is clamped on the bottom plate 1. The structure sets the needle 2 as two groups, and because the two groups of needles 2 are in a cross structure when extending from the surface of the bottom plate 1, the plastic part 10 is limited by the two groups of needles 2 in the horizontal and vertical directions and cannot move, so that the plastic part 10 can be stably clamped on the surface of the bottom plate 1, achieving the function and purpose of clamping the plastic part 10 on the bottom plate 1, and having the advantages of ingenious structure design, fast clamping speed and high efficiency. The two groups of needles 2 can be simultaneously arranged at one position of the left side, the middle and the right side of the bottom plate 1, or the two groups of needles 2 are arranged at two positions of the left side, the middle and the right side respectively.

[0033] The two groups of needles 2 are arranged on the two sides of the bottom plate 1 respectively. Arranging the two groups of needles 2 on the two sides (two ends) of the bottom plate 1 respectively can make the needles 2 respectively prick the two ends of the plastic part 10, so that the two ends of the plastic part 10 are clamped on the bottom plate 1, ensuring the stability of the overall connection between the plastic part 10 and the bottom plate 1.

[0034] The bottom plate 1 is provided with a through hole 11, and the front end of the lancet 2 extends out of or retracts into the surface of the bottom plate 1 through the through hole 11; or the bottom plate 1 is nested with an embedded block 4 provided with a through hole 11, and the front end of the lancet 2 extends out of or retracts into the surface of the bottom plate 1 through the through hole 11. The lancet 2 is slidably sleeved in the through hole 11. When the driving device 3 drives the lancet 2 to extend out of or retract into the surface of the bottom plate 1, the lancet 2 slides forward or backward along the through hole 11 under the guidance of the through hole 11. In addition, the technical scheme of nesting the embedded block 4 provided with the through hole 11 on the bottom plate 1 can adjust the angle at which the lancet 2 penetrates into the plastic part 10 by replacing the embedded block 4 provided with the through hole 11 with different angles, so as to achieve the purpose of achieving the required clamping effect, and has the advantages of convenient adjustment and strong adaptability.

[0035] The driving device 3 is a pneumatic cylinder or a hydraulic cylinder, and the piston rod of the pneumatic cylinder or the hydraulic cylinder is fixedly connected with the lancet 2. The working state of the piston rod of the pneumatic cylinder or the hydraulic cylinder is controlled to control the lancet 2 to extend out of or retract into the surface of the bottom plate 1.

[0036] As shown in Figure 1 and Figure 4 The bottom plate 1 is arranged on a horizontal moving platform 5. The horizontal moving platform 5 drives the bottom plate 1 to move in the horizontal or vertical direction, so as to transport the plastic part 10 arranged on the bottom plate 1 into the oil tank.

[0037] The horizontal moving platform 5 comprises a base 51 and a second driving device 52 arranged on the base 51 and used for driving the bottom plate 1, the lancet 2 and the driving device 3 to move. When the second driving device 52 drives the bottom plate 1 to move, the bottom plate 1 drives the lancet 2 and the driving device 3 to move simultaneously, so as to transport the plastic part 10 arranged on the bottom plate 1 into the oil tank.

[0038] The horizontal moving platform 5 is provided with a stop rod 6 used for positioning the plastic part 10. The stop rod 6 is arranged in plurality and arranged along the edge of the horizontal moving platform 5 to form a shape corresponding to the outer contour shape of the plastic part 10. The worker only needs to place the plastic part 10 into the shape surrounded by the stop rod 6, so as to accurately arrange the plastic part 10 on the bottom plate 1 at the required position, which greatly facilitates the operation of the work.

[0039] The second driving device 52 comprises a motor 53 and a support plate 54, and the bottom plate 1 is arranged on the support plate 54. The bottom plate 1 is arranged on the support plate. When the motor 53 drives the support plate 54 to move, the support plate 54 drives the bottom plate 1, the lancet 2 and the driving device 3 to move simultaneously, so as to transport the plastic part 10 arranged on the bottom plate 1 into the oil tank.

[0041] This embodiment is based on the structure of the needle 2 as an improvement, as shown in Figure 2 and Figure 3 The needle 2 is provided with two groups, and the two groups of the needle 2 are respectively arranged on the two sides of the bottom plate 1. Each group of the needle 2 includes at least two needles 2, and the included angle between the front ends of the two needles 2 is greater than zero degrees, so that the plastic part 10 is clamped on the bottom plate 1. Each group of the needle 2 on each side of the bottom plate 1 includes at least two needles 2, and the front ends of the two needles 2 cross each other when they are stretched out to pierce into the plastic part 10, so that each end of the plastic part 10 is limited by the two needles 2 in the horizontal and vertical directions and cannot move, which can better prevent the plastic part 10 from being pulled out of the needle 2, so that each end of the plastic part 10 is clamped on the bottom plate 1, and the overall connection stability between the plastic part 10 and the bottom plate 1 is greatly improved.
