[0036] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0037] In the description of the utility model, it is understood that the orientation description, such as the orientation or positional relationship of up, down, in, out and the like, is based on the orientation or positional relationship shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0038] In the description of the utility model, if the first and second are described for the purpose of distinguishing technical features, they cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the sequence of technical features indicated.

[0039] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be understood broadly, and the skilled person in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0040] In the related art, after a series of processing, the lens needs to be blown up by the air blowing device to blow off the dust attached to the surface of the lens. In order to ensure that the lens does not separate from the carrier plate loading the lens during the air blowing process, a limiting piece is usually arranged to limit the moving distance of the lens. However, in actual operation, the limiting piece is easy to rotate axially when moving, and the relative position of the limiting piece and the lens is easy to deviate, thereby causing the limiting piece to collide or rub with the lens, and further causing damage to the lens.

[0041] Therefore, some embodiments of the utility model provide an air blowing device 1000 applied to a lens processing equipment 3000, and the air blowing device 1000 is specifically described with reference to Figures 1 to 8 .

[0042] Referring to Figure 1 and Figure 2 , in the utility model embodiment, the air blowing device 1000 comprises a carrier plate 100, an air blowing base 200, a jig plate 300 and a plurality of limiting pieces 400, the carrier plate 100 loads a plurality of workpieces 2000, and specifically, the plurality of workpieces 2000 are evenly distributed in the carrier plate 100. In this embodiment, the air blowing base 200 is arranged on one side of the carrier plate 100, and specifically, the air blowing base 200 is located on the lower side of the carrier plate 100 and covers the carrier plate 100.

[0043] Referring to Figure 2 , Figure 3 and Figure 4As shown in the figure, in the embodiment, the jig plate 300 is arranged on the side of the carrier plate 100 away from the blowing base 200 and detachably connected with the carrier plate 100. Specifically, the jig plate 300 is arranged on the upper side of the carrier plate 100. In the embodiment, the jig plate 300 and the carrier plate 100 can be connected by fasteners, can be connected by buckles, or can be connected by other forms of detachable connection, which is not limited in the embodiment. Based on this, it can be understood that when the blowing device 1000 completes the blowing operation, the carrier plate 100 needs to be quickly replaced to start a new round of blowing operation. The detachable connection can quickly detach or install the carrier plate 100 and the jig plate 300, thereby improving the disassembly and assembly efficiency and further improving the production efficiency.

[0044] Referring to Figure 2 , Figure 5 and Figure 7 , in the embodiment, the jig plate 300 is provided with a plurality of limiting grooves 310 arranged at intervals, and the plurality of limiting grooves 310 correspond one-to-one to the plurality of workpieces 2000. Specifically, the limiting grooves 310 penetrate the jig plate 300 along the connecting direction of the jig plate 300 and the carrier plate 100, and the plurality of limiting grooves 310 are uniformly and evenly distributed. The distribution state of the plurality of limiting grooves 310 matches the distribution state of the plurality of workpieces 2000. In the embodiment, the plurality of limiting grooves 310 can be arranged in a rectangular array or in a circular array. In the embodiment, a plurality of limiting pieces 400 are arranged one-to-one in the plurality of limiting grooves 310. The limiting pieces 400 correspond to the workpieces 2000, and the limiting pieces 400 are slidably connected with the limiting grooves 310. Specifically, the limiting pieces 400 are arranged on the side of the workpieces 2000 away from the blowing base 200, the limiting pieces 400 are arranged in the limiting grooves 310, and the limiting pieces 400 can slide along the limiting grooves 310.

[0045] Referring to Figure 5 , Figure 6 and Figure 7As shown in the utility model embodiment, the inner circumferential wall of the limiting groove 310 is provided with a first abutting face 311, and the outer circumferential wall of the limiting piece 400 is provided with a second abutting face 411 matched with the first abutting face 311, and it can be understood that the inner circumferential wall of the limiting groove 310 and the outer circumferential wall of the limiting piece 400 are matched, and the first abutting face 311 corresponds to the second abutting face 411. In the embodiment, the air blowing base 200 can blow air to the workpiece 2000, so that the workpiece 2000 pushes the limiting piece 400 to move along the limiting groove 310, and the first abutting face 311 is attached to the second abutting face 411 to limit the axial rotation of the limiting piece 400. Specifically, the air blowing base 200 blows air to the workpiece 2000 towards the upper side, the workpiece 2000 is blown up by the air flow generated by blowing air and moves towards the limiting piece 400 until abutting with the limiting piece 400, the workpiece 2000 pushes the limiting piece 400 to move along the limiting groove 310, and since the first abutting face 311 and the second abutting face 411 can be attached during the movement of the limiting piece 400, the axial rotation of the limiting piece 400 can be limited.

[0046] Therefore, by attaching the first abutting face 311 and the second abutting face 411 to each other, the axial rotation of the limiting piece 400 during movement is limited, the stability of the movement of the limiting piece 400 along the limiting groove 310 is improved, the risk of collision between the limiting piece 400 and the workpiece 2000 is reduced, the possibility of the limiting piece 400 pressing the surface of the workpiece 2000 is reduced, and the reliability of the air blowing device 1000 is improved.

[0047] Referring to Figure 5 , Figure 6 and Figure 7 , in the utility model embodiment, the limiting piece 400 is provided with a plurality of second abutting faces 411, and the limiting piece 400 has a first side 440 and a second side 450 opposite to each other, and it can be understood that the outer circumferential wall of the limiting piece 400 has two opposite sides, and in the embodiment, the two opposite sides of the outer circumferential wall of the limiting piece 400 can be the left and right sides, the front and back sides or other direction sides of the limiting piece 400, and the embodiment does not limit this. In one example, along the length direction of the air blowing device 1000, the left side of the outer circumferential wall of the limiting piece 400 is the first side 440, and the right side is the second side 450.

[0048] Referring to Figure 5 , Figure 6 and Figure 7As shown, in the embodiment, the first side 440 is provided with N second abutting surfaces 411, and the second side 450 is provided with N+1 second abutting surfaces 411, N is an integer and N>=1. It can be understood that the number of the second abutting surfaces 411 matches the number of the first abutting surfaces 311. Based on this, since the two opposite sides of the peripheral wall of the limiting piece 400 are provided with an unequal number of second abutting surfaces 411, when the limiting piece 400 is installed in the limiting groove 310, the installation direction of the limiting piece 400 can be easily distinguished, reducing the possibility of incorrect installation of the limiting piece 400, thereby improving the accuracy of installation, avoiding the collision between the limiting piece 400 and the workpiece 2000 due to incorrect installation of the limiting piece 400, and further improving the reliability of the air blowing device 1000.

[0049] Referring to Figure 3 , Figure 4 and Figure 5 , in the embodiment, the side of the jig plate 300 opposite to the carrier plate 100 is provided with a limiting plate 320, and the limiting plate 320 is connected to the jig plate 300. Specifically, the jig plate 300 and the limiting plate 320 are in a split structure, the limiting plate 320 is located on the upper side of the jig plate 300 and covers the jig plate 300. In the embodiment, the limiting plate 320 and the jig plate 300 can be connected by fasteners, or can be connected by other connection methods such as buckling connection, and the embodiment does not limit this.

[0050] Referring to Figure 2 , Figure 4 and Figure 5 , in the embodiment, the air blowing device 1000 further comprises a plurality of reset pieces 500, and the plurality of reset pieces 500 correspond one-to-one to the plurality of limiting pieces 400. One end of the reset piece 500 is connected to the limiting plate 320, and the other end is connected to the limiting piece 400. Specifically, the reset piece 500 is located between the limiting piece 400 and the limiting plate 320, the upper end of the reset piece 500 is connected to the limiting plate 320, and the lower end is connected to the limiting piece 400. In the embodiment, the reset piece 500 can be a gas cylinder, an elastic piece or the like, and the embodiment does not limit this. Based on this, when the workpiece 2000 pushes the limiting piece 400 to move, the limiting plate 320 will limit the movement distance of the limiting piece 400, thereby limiting the limiting piece 400 from disengaging upward from the jig plate 300; when the air blowing base 200 completes the air blowing operation, the reset piece 500 will push the limiting piece 400 to move towards the workpiece 2000, and the limiting piece 400 will return to the initial position, and at the same time, the workpiece 2000 will also return to the initial position, thereby completing the reset of the limiting piece 400 and the workpiece 2000.

[0051] Referring to Figure 2 , Figure 4 and Figure 5As shown in the utility model embodiment, the reset member 500 is a spring, the surface of the limiting member 400 away from the carrier plate 100 is provided with an installation hole 420 with an opening facing the limiting plate 320, one end of the reset member 500 abuts against the bottom wall of the installation hole 420, and the other end abuts against the limiting plate 320. Specifically, the upper surface of the limiting member 400 is recessed to form the installation hole 420 away from the limiting plate 320, the opening of the installation hole 420 faces the upper side of the limiting member 400, the lower end of the reset member 500 is arranged in the installation hole 420 and abuts against the bottom wall of the installation hole 420, and the upper end of the reset member 500 directly abuts against the lower surface of the limiting plate 320.

[0052] It can be understood that the spring has good buffering performance, the limiting member 400 and the limiting plate 320 are connected through elasticity, and when the limiting member 400 and the workpiece 2000 are reset, the collision during resetting can be buffered, the possibility of damaging the workpiece 2000 due to the collision is reduced, and thus the reliability of the air blowing device 1000 is improved. Based on this, the spring is used as the reset member 500, that is, the manufacturing cost of the air blowing device 1000 can be reduced, the limiting member 400 and the workpiece 2000 can be quickly reset after the air blowing operation is completed, and thus the working efficiency of the air blowing device 1000 is improved.

[0053] Referring to Figure 2 , Figure 4 and Figure 5 As shown in the utility model embodiment, the limiting member 400 comprises a limiting portion 410 and a guiding portion 430 connected with each other. In the embodiment, the limiting portion 410 and the guiding portion 430 can be integrally formed or connected through welding or other connection modes, and the embodiment does not limit this. The limiting portion 410 is located on the side of the limiting member 400 away from the carrier plate 100, and the outer peripheral wall of the limiting portion 410 is provided with a second abutting surface 411. Specifically, the upper end of the limiting member 400 is the limiting portion 410, and part of the side wall of the outer peripheral wall of the limiting portion 410 is the second abutting surface 411.

[0054] Referring to Figure 2 , Figure 4 and Figure 5As shown, in the embodiment, the guide part 430 is located on the side of the limiting part 410 facing the carrier plate 100, and the guide part 430 is provided with a first avoiding groove 431 with an opening facing the workpiece 2000, the workpiece 2000 is arranged in the first avoiding groove 431, and the outer peripheral wall of the workpiece 2000 is arranged in a spaced manner with the inner peripheral wall of the first avoiding groove. Specifically, the lower end of the limiting part 400 is the guide part 430, the lower side surface of the guide part 430 is recessed to form the first avoiding groove 431, and the opening of the first avoiding groove 431 faces the lower side of the guide part 430. It can be understood that there is a gap between the outer peripheral wall of the workpiece 2000 and the inner peripheral wall of the first avoiding groove, and when the workpiece 2000 moves towards the limiting part 400 and is arranged in the first avoiding groove 431, the outer peripheral wall of the workpiece 2000 will not contact the inner peripheral wall of the first avoiding groove until the upper side surface of the workpiece 2000 abuts against the bottom wall of the first avoiding groove 431, thereby pushing the limiting part 400 to move along the limiting groove 310. Based on this, the accuracy of the abutment between the workpiece 2000 and the limiting part 400 is improved, thereby improving the stability of the process of pushing the limiting part 400 to move by the workpiece 2000, and further improving the reliability and stability of the air blowing device 1000.

[0055] It can be understood that if the circumferential gap between the first avoiding groove 431 and the workpiece 2000 is too small, when the jig plate 300 is covered on the carrier plate 100, if the center positions of the workpiece 2000 and the limiting part 400 do not coincide or have a large deviation, the workpiece 2000 cannot be accurately arranged in the first avoiding groove 431, and the workpiece 2000 cannot abut against the limiting part 400 correctly, thereby causing the limiting part 400 to collide with the workpiece 2000, and further increasing the possibility of damaging the workpiece 2000. Therefore, with reference to Figure 5 As shown, in the embodiment, the distance between the outer peripheral wall of the workpiece 2000 and the inner peripheral wall of the first avoiding groove 431 is L, which satisfies: L≥1mm (millimeter), it can be understood that as long as the deviation of the center positions of the workpiece 2000 and the limiting part 400 is ensured to be within 1mm, the workpiece 2000 will be accurately arranged in the first avoiding groove 431 and abut against the limiting part 400, thereby reducing the possibility of collision between the limiting part 400 and the workpiece 2000, reducing the risk of damage to the workpiece 2000, and further improving the reliability and stability of the air blowing device 1000.

[0056] With reference to Figure 4 , Figure 5 and Figure 6As shown in the utility model embodiment, the inner peripheral wall of the limiting groove 310 is provided with a step 312, the limiting portion 410 is at least partially located on the step 312, the step 312 and the limiting portion 410 abut, so as to limit the movement of the limiting portion 410 towards the workpiece 2000. Specifically, the limiting groove 310 comprises a first groove section 3101 and a second groove section 3102 arranged in sequence along the direction of the workpiece 2000 towards the limiting piece 400, along the direction of the connecting line of the workpiece 2000 and the limiting piece 400, the projection of the first groove section 3101 is within the outer contour of the projection of the second groove section 3102, therefore, the step 312 is formed at the joint of the first groove section 3101 and the second groove section 3102, the guide portion 430 is arranged in the first groove section 3101, and the limiting portion 410 is arranged in the second groove section 3102. It can be understood that when the reset piece 500 pushes the limiting piece 400 to move downwards, the side surface peripheral edge of the limiting portion 410 towards the guide portion 430 abuts against the step 312, so as to limit the downward disengagement of the limiting piece 400 from the limiting groove 310.

[0057] Referring to Figure 4 , Figure 5 and Figure 6 As shown in the utility model embodiment, the side of the jig plate 300 towards the carrier plate 100 is provided with a positioning groove 330, the side of the carrier plate 100 towards the jig plate 300 is provided with a positioning portion 110, a plurality of workpieces are installed in the positioning portion at intervals, and the positioning portion 110 is arranged in the positioning groove 330. Specifically, the lower side surface of the jig plate 300 is recessed to form the positioning groove 330, the opening of the positioning groove 330 faces downwards, the upper side surface of the carrier plate 100 protrudes to form the positioning portion 110 towards the jig plate 300, and when the jig plate 300 is connected with the carrier plate 100, the positioning portion 110 is arranged in the positioning groove 330. In the embodiment, a plurality of workpieces 2000 are uniformly distributed and movably installed in the positioning portion 110, so that the air blowing base 200 blows up the workpieces. Based on this, the jig plate 300 can be quickly positioned with the carrier plate 100, thereby improving the installation efficiency of the jig plate 300 and the carrier plate 100, and also improving the connection accuracy of the jig plate 300 and the carrier plate 100.

[0058] Referring to Figure 4 , Figure 5 and Figure 6As shown, the embodiment of the utility model further proposes a lens processing equipment 3000, including the air blowing device 1000 of above-mentioned embodiment. Air blowing device 1000 is provided with multiple limit grooves 310 by being arranged in jig plate 300, multiple limit pieces 400 are correspondingly arranged in multiple limit grooves 310, limit piece 400 is correspondingly arranged with workpiece 2000, limit piece 400 and limit groove 310 are slidingly connected, first abutment surface 311 is arranged in the inner circumferential wall of limit groove 310, and second abutment surface 411 is arranged in the outer circumferential wall of limit piece 400, when air blowing base 200 blows air to workpiece 2000 and makes workpiece 2000 push limit piece 400 to move along limit groove 310, limit piece 400 limits workpiece 2000 to separate from carrier plate 100, simultaneously, first abutment surface 311 and second abutment surface 411 are attached, thereby limit the rotation of limit piece 400, based on this, improve the stability of limit piece 400 when moving along limit groove 310, thereby reduce the risk of limit piece 400 and workpiece 2000 collision, reduce the possibility of limit piece 400 damaging the surface of workpiece 2000, further improve the reliability of air blowing device 1000, further, reduce the defective rate of workpiece 2000, improve the production quality of workpiece 2000, thereby improve the reliability and stability of lens processing equipment 3000, further improve the use performance of lens processing equipment 3000.
