Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of suction nozzles, in particular to a limiting suction nozzle. Background Art
[0002] In the production process of surface mounting, since the components are generally small in size and light in weight, they are prone to shaking during adsorption and pressing, so the suction nozzle is likely to have an unstable adsorption problem when adsorbing the components.
[0003] In the prior art, in order to solve the above problems, suction control is often increased. By using a more precise pneumatic control system, it is ensured that the suction nozzle can provide stable suction, or a vision detection system is used during adsorption and placement to monitor and adjust the position of the components in real time, so as to ensure that the suction nozzle can accurately adsorb and place the components. However, both the pneumatic control system and the vision detection system have relatively high costs. Summary of the Utility Model
[0004] Aiming at the above problems in the prior art, the utility model provides a limiting suction nozzle, which solves the problem that the existing suction nozzle is prone to unstable adsorption of components.
[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] Provide a limiting suction nozzle, including a suction nozzle body. The suction nozzle body includes a suction nozzle plate. An air inlet joint is arranged on the top surface of the suction nozzle plate, and the air inlet joint is in a conical structure with both ends open; a limiting plate for limiting components is fixed on the bottom surface of the suction nozzle plate. The limiting plate is in a U-shaped plate structure. At least two suction nozzle holes are opened on the top plate of the limiting plate. A suction nozzle head is arranged in each suction nozzle hole of the suction nozzle plate, and each suction nozzle head is communicated with the bottom of the air inlet joint through a negative pressure channel in the suction nozzle plate.
[0007] The working principle of this scheme is that before the limiting suction nozzle adsorbs the components, the components will be limited by the limiting plate first. The movement freedom of the two side surfaces of the components is restricted by the limiting plate. Therefore, during the downward pressing and adsorption process of each suction nozzle head on the components, the position of the components will not change greatly, and the components will not fall off due to moving inertia or the shaking of the limiting suction nozzle during the moving process, improving the stability of the adsorption of the components.
[0008] Further, the top view projection of the suction nozzle plate is in a rectangular shape with both short sides being arcs, and a U-shaped sunk groove is arranged on the top surfaces of the two arc plates of the suction nozzle plate. The setting of the U-shaped sunk groove is convenient for the external mounter or other fixing devices to limit the fixing position of the suction nozzle plate.
[0009] Further, the two U-shaped sunk grooves are symmetrically arranged along the central axis of the air inlet joint.
[0010] Further, the large-diameter end of the air inlet joint is fixed on the nozzle plate, and two clamping grooves are symmetrically arranged on the outer wall of the large-diameter end of the air inlet joint. The arrangement of the clamping grooves facilitates the clamping connection of the air inlet joint with an external negative pressure device.
[0011] Further, each nozzle hole of the limit plate is located on the center line of the top plate of the limit plate. By setting the position of the nozzle holes in this way, each nozzle head is located on the center line of the component, improving the adsorption stability.
[0012] Further, the center line passing through the two open ends on the limit plate coincides with the center line passing through the two arc plates on the nozzle plate. By setting the opening direction of the limit plate in this way, it is beneficial to ensure the length of the limit plate.
[0013] Further, the width between the two side plates of the limit plate is 1.1 to 1.3 times the width of the component, which not only ensures that the component can enter the limit plate, but also ensures that the component will not deviate greatly within the U-shape during the adsorption process.
[0014] Further, the material of the limit plate is polyoxymethylene. Polyoxymethylene is an engineering plastic with excellent mechanical strength and rigidity.
[0015] Further, the material of the nozzle head is rubber. Rubber has elasticity, which can avoid damaging the component during the adsorption process.
[0016] The utility model discloses a limit nozzle, and its beneficial effects are as follows:
[0017] Before adsorbing the component, the utility model first limits the component through the limit plate and then adsorbs it. Therefore, during the downward pressing and adsorption process of each nozzle head on the component, the position of the component will not change greatly, and the component will not fall off due to inertia or the shaking of the limit nozzle during the moving process. This not only improves the adsorption stability of the component, but also has a low cost. Description of the Drawings

[0022] The specific embodiments of the present utility model will be described below to facilitate those skilled in the art to understand the present utility model. However, it should be clear that the present utility model is not limited to the scope of the specific embodiments. For those ordinary skilled in the art, as long as various changes are within the spirit and scope of the present utility model defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the present utility model are within the scope of protection.
[0023] This embodiment provides a limiting suction nozzle, which includes a suction nozzle body.
[0024] Referring to Figure 1 , the suction nozzle body includes a suction nozzle plate 1. The top view projection of the suction nozzle plate 1 is in the shape of a rectangle with both short sides being arcs. One U-shaped sunk groove 11 is provided on the top surfaces of the two arc plates of the suction nozzle plate 1, and the two U-shaped sunk grooves 11 are symmetrically arranged along the central axis of the air inlet joint 2. The setting of the U-shaped sunk groove 11 facilitates the external mounter or other fixing devices to limit the fixing position of the suction nozzle plate 1.
[0025] An air inlet joint 2 is provided on the top surface of the suction nozzle plate 1. The air inlet joint 2 has a conical structure with both ends open. The large-diameter end of the air inlet joint 2 is fixed on the suction nozzle plate 1, and two clamping grooves 21 are symmetrically arranged on the outer wall of the large-diameter end of the air inlet joint 2. The setting of the clamping grooves 21 facilitates the air inlet joint 2 to be clamped with the negative pressure port of the external negative pressure device.
[0026] A limiting plate 3 for limiting components is fixed on the bottom surface of the suction nozzle plate 1.
[0027] Referring to Figure 2 and Figure 3 , the limiting plate 3 has a U-shaped plate structure. At least two suction nozzle holes are provided on the top plate of the limiting plate 3. In this embodiment, it is preferably 3. The suction nozzle plate 1 is provided with a suction nozzle head 4 in each suction nozzle hole, and each suction nozzle head 4 is communicated with the bottom of the air inlet joint 2 through a negative pressure channel in the suction nozzle plate 1.
[0028] In this embodiment, the material of the limiting plate 3 is polyoxymethylene. Polyoxymethylene is an engineering plastic with excellent mechanical strength and rigidity. The material of the suction nozzle head 4 is rubber. Rubber has elasticity to avoid damaging components during the adsorption process.
[0029] In order to further improve the adsorption stability, each suction nozzle hole of the limiting plate 3 is located on the center line of the top plate of the limiting plate 3. By setting the position of the suction nozzle holes in this way, each suction nozzle head 4 is located on the center line of the component.
[0030] In order to ensure that the length of the limiting plate 3 is not limited by the width of the suction nozzle plate 1, the center line passing through both ends of the limiting plate 3 coincides with the center line passing through the two arc plates of the suction nozzle plate 1.
[0031] To ensure that the components can enter the limit plate 3 and at the same time ensure that the components will not have a large deviation within the U-shape during the adsorption process. The width between the two side plates of the limit plate 3 is 1.1 to 1.3 times the width of the components.
[0032] In summary, the working principle of this solution is as follows:
[0033] Before the limit suction nozzle adsorbs the components, it first limits the components through the limit plate 3. The degrees of freedom of movement of the two side surfaces of the components are restricted by the limit plate 3. Therefore, during the process of each suction nozzle head 4 pressing down and adsorbing the components, the position of the components will not change significantly, and the components will not fall off due to moving inertia or the shaking of the limit suction nozzle during the moving process, improving the stability of the adsorption of the components.
[0034] Although the specific implementation mode of the utility model has been described in detail with reference to the drawings, it should not be construed as a limitation on the protection scope of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative labor still fall within the protection scope of this patent.
