DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 This application is described in further detail.

[0021] The present application embodiment discloses a special suction nozzle for automatic suction and placement of LED concave lens elements integrally formed, referring to Figure 1 In this embodiment, the special suction nozzle includes a suction nozzle body, a suction nozzle mounting seat 4 and a suction nozzle head 6. One end of the suction nozzle body is mounted at the suction end of the placement machine, and the suction nozzle mounting seat 4 is mounted on the side of the suction nozzle body away from the suction end of the placement machine; specifically, the suction nozzle body and the suction nozzle mounting seat 4 are made by an integrated molding processing method. Through such an integrated molding processing method, not only the concentricity of the suction nozzle is consistent, thereby solving the problem that the existing standard suction nozzles are all inlaid bodies and cause a certain error in their concentricity; and the integrated molding processing method can also improve the stability of the suction nozzle and ensure its own strength.

[0022] More specifically, in the present embodiment, the nozzle body and the nozzle mounting seat 4 are both made of stainless steel. By providing the nozzle body and the nozzle mounting seat 4 made of stainless steel, the nozzle body and the nozzle mounting seat 4 are easy to process, rust-proof, wear-resistant, and not prone to scratches, thereby increasing the service life of the special nozzle of the present application, thereby saving resources and costs.

[0023] At the same time, the nozzle head 6 is embedded in the side of the nozzle mounting seat 4 away from the nozzle body, and a mounting notch 41 is provided on the side of the nozzle mounting seat 4 away from the nozzle body. The nozzle head 6 is firmly embedded in the mounting notch 41, and the embedded nozzle head 6 must be ensured to be consistent with the center of the integrally formed nozzle body and the nozzle mounting seat 4. The suction plane of the nozzle head 6 must be ensured to be vertical to the nozzle body and the nozzle mounting seat 4 at the same time, and the imaging surface needs to be finely processed to ensure a smooth plane.

[0024] Preferably, the nozzle head 6 is made of white POM material. By providing the nozzle head 6 of white POM material, it is not only convenient to stably adsorb the LED concave lens element, but also can achieve the function of adsorbing the arc surface or achieving the imaging requirement, and the effect of imaging with a white background is better; it can also have the effect of wear resistance and the surface is not easy to be scratched.

[0025] In addition, mutually interconnected negative pressure pipelines 5 are opened at the inner centers of the nozzle body and the nozzle mounting seat 4, and the negative pressure pipeline 5 is interconnected with the mounting groove 41, and an adsorption hole 61 is opened at the inner center of the nozzle head 6, and the adsorption hole 61 is interconnected with the negative pressure pipeline 5 to form an air path, and the air path must be guaranteed to be free of blockage and impurities during processing; at the same time, consistent concentricity is also required.

[0026] The structure of the nozzle body and the nozzle mounting seat 4 is described in detail below:

[0027] Specifically, refer to Figure 1 In this embodiment, the nozzle body includes a nozzle connection seat 1, a nozzle center tube seat 2 and a nozzle connection head 3. The nozzle connection seat 1, the nozzle center tube seat 2 and the nozzle connection head 3 are integrally formed; specifically, the nozzle connection seat 1 is installed on the side of the nozzle mounting seat 4 away from the nozzle head 6, the diameter of the side of the nozzle connection seat 1 close to the nozzle mounting seat 4 is larger than the diameter of the other side, and the outer side thereof is in an arc-shaped structure, which can improve stability.

[0028] The center tube seat 2 of the suction nozzle is a circular tubular structure, and one end of the center tube 2 of the suction nozzle is interconnected with the side of the suction nozzle connecting seat 1 away from the suction nozzle mounting seat 4; one end of the suction nozzle connecting head 3 is interconnected with the end of the center tube 2 of the suction nozzle away from the suction nozzle connecting seat 1, and the other end of the suction nozzle connecting head 3 is installed in cooperation with the adsorption end of the placement machine equipment, so as to facilitate the stable installation of the suction nozzle body at the adsorption end of the placement machine equipment.

[0029] More specifically, the negative pressure pipeline 5 is simultaneously opened inside the nozzle connector 3, the nozzle center tube seat 2 and the nozzle connecting seat 1; and a matching slot 31 is opened through the inside of the nozzle connector 3, and the matching slot 31 is installed in coordination with the adsorption end of the placement machine equipment, and the matching slot 31 extends to one end of the nozzle center tube seat 2, so that the matching slot 31 and the negative pressure pipeline 5 are connected to each other.

[0030] By setting the matching slot 31, the adsorption end of the placement machine equipment can be inserted into the matching slot 31, which not only makes the adsorption end of the placement machine equipment and the suction nozzle connector 3 more tightly matched and installed, thereby improving the air tightness; but also can effectively guide and position the installation of the adsorption end of the placement machine equipment.

[0031] Preferably, an arc groove 32 is symmetrically provided on the inner side of the end of the nozzle connector 3 away from the nozzle center tube seat 2, and the arc groove 32 is connected to the matching notch 31; the setting of the arc groove 32 can further improve the airtightness when it is matched with the adsorption end of the placement machine equipment. At the same time, it can also play an effective protection effect when matched with the installation.

[0032] Secondly, refer to Figure 1In the present embodiment, a U-shaped notch 33 is symmetrically provided at one end of the nozzle connector 3 away from the nozzle center tube seat 2, and the two U-shaped notches 33 are respectively interconnected with the matching notches 31, and the U-shaped notches 33 cooperate with the positioning components on the placement machine equipment; through the setting of the two U-shaped notches 33, the adsorption end of the placement machine equipment can be effectively positioned and matched; at the same time, the two U-shaped notches 33 are integrally formed, which can save materials and reduce costs.

[0033] At the same time, a limiting groove 34 is opened on the outer side of one end of the nozzle connector 3 close to the nozzle center tube socket 2. The limiting groove 34 is a circular structure, and the limiting groove 34 is firmly installed with the limiting component on the placement machine equipment; in addition, an inclined surface 35 is symmetrically opened on the outer side of the end of the nozzle connector 3 away from the nozzle center tube socket 2, and the inclined surface 35 can play an effective guiding installation effect.

[0034] When the nozzle body needs to be installed, the matching slot 31 in the nozzle connector 3 is matched with the adsorption end of the placement machine equipment, and the limiting component on the placement machine equipment is firmly sleeved in the limiting slot 34 in the nozzle connector 3 to achieve stable limiting of the nozzle connector 3.

[0035] In addition, refer to Figure 1 In the present embodiment, the nozzle mounting base 4 is in a rectangular structure, and rounded corners are provided on both sides of the nozzle mounting base 4. The setting of the rounded corners can not only remove burrs to protect the LED concave lens element, but also achieve an overall aesthetic effect.

[0036] When it is necessary to adsorb the LED concave lens element, the adsorption part on the placement machine is started to generate suction at the adsorption hole 61 of the nozzle head 6, and the gas forms an air path along the adsorption hole 61 and the negative pressure pipeline 5 in turn to adsorb the LED concave lens element, so that the LED concave lens element is tightly fitted with the adsorption surface of the nozzle head 6, thereby completing the adsorption process of the LED concave lens element.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
