Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical hand technical field especially relates to a novel suction nozzle structure. BACKGROUND

[0002] In the semiconductor process, the chip needs to be moved from one position to another position in the process of testing or pasting, and the chip movement needs to be vacuumed by the suction nozzle.

[0003] The chip size is very small, and the suction nozzle for sucking the chip is also small. The existing suction nozzle has the disadvantages of being not conducive to visual positioning of the camera, being not easy to seal, being easy to leak, and needing to plug and unplug the air pipe when replacing the suction nozzle. SUMMARY

[0004] The utility model embodiment solves the technical problem that the utility model provides a novel suction nozzle structure to facilitate the visual positioning of the camera.

[0005] In order to solve the above technical problem, the utility model provides a novel suction nozzle structure, which comprises a suction nozzle part and a vacuum pipe joint, a gas passage is arranged in the suction nozzle part and penetrates up and down, the bottom end of the gas passage is a suction port, a lens is arranged at the top end of the gas passage to seal the gas passage, and the vacuum pipe joint is arranged on the suction nozzle part and communicates with the gas passage.

[0006] Further, the suction nozzle part is composed of a suction nozzle fixing seat and a suction nozzle, and the suction nozzle is arranged at the bottom of the suction nozzle fixing seat.

[0007] Further, the suction nozzle structure further comprises a suction nozzle gland and a lower O-shaped ring, the suction nozzle and the suction nozzle fixing seat are sealed by the lower O-shaped ring, and the suction nozzle gland presses the suction nozzle on the suction nozzle fixing seat.

[0008] Further, the suction nozzle gland is screwed between the suction nozzle fixing seat.

[0009] Further, the suction nozzle structure further comprises a lens gland and an upper O-shaped ring, the lens seals the top end of the gas passage through the upper O-shaped ring, and the lens gland presses the lens on the suction nozzle fixing seat.

[0010] The utility model has the advantages that the utility model facilitates the camera to shoot the image below the suction nozzle, thereby quickly and accurately positioning the vision, the utility model solves the problem of air leakage, can facilitate the user to quickly replace the suction nozzle, and has the simple structure and small size.

[0017] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present application will be further described in detail in combination with the drawings and specific embodiments.

[0018] In the embodiments of the present application, directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0019] In addition, in the present application, the description of "first", "second", etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.

[0020] Please refer to Figures 1-4 The novel nozzle structure in the embodiment of the present application comprises a nozzle part and a vacuum pipe joint.

[0021] The nozzle part is internally provided with an air passage penetrating up and down. The bottom end of the air passage is a suction port, and the chip is sucked through the suction port. The top end of the air passage is provided with a lens for sealing the air passage, and the vacuum pipe joint is arranged on the nozzle part and communicates with the air passage.

[0022] As an embodiment, the nozzle part is composed of a nozzle fixing seat and a nozzle, and the nozzle is mounted at the bottom of the nozzle fixing seat. That is, the air passage penetrates through the nozzle fixing seat and the nozzle, and is divided into two sections, the upper section is located in the nozzle fixing seat, and the lower section is located in the nozzle. The vacuum pipe joint is mounted on the nozzle fixing seat, the bottom end of the nozzle is a suction port, and the chip is sucked through the suction port.

[0023] As an implementation, the new nozzle structure further comprises a nozzle gland and a lower O-ring, the nozzle and the nozzle fixing seat are sealed by the lower O-ring, and the nozzle gland is used to press the nozzle on the nozzle fixing seat. Preferably, the nozzle gland is screwed with the nozzle fixing seat, which is convenient for users to quickly replace the nozzle. The top of the nozzle is inserted into the nozzle fixing seat.

[0024] As an implementation, the new nozzle structure further comprises a lens gland and an upper O-ring, the lens seals the airway top end through the upper O-ring, the lens gland is used to press the lens on the nozzle fixing seat, which is convenient for users to disassemble and replace. The lens can be a plane lens, a convex lens, a concave lens, etc. according to specific needs.

[0025] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
