Description

Technical Field

[0001] This utility model relates to the field of non-standard automated processing technology, specifically a suction nozzle limit protection device. Background Technology

[0002] When mounting soft components, a nozzle is needed in conjunction with a displacement mechanism to facilitate the transfer and installation of the components. Existing nozzle structures are mainly fixed rod structures, which lack limiting protection during the mounting process of soft components. This leads to problems such as difficulty in controlling the pressing stroke and force, which can easily cause damage to the soft components. To address these issues, a nozzle limiting protection device is designed to better meet practical needs. Utility Model Content

[0003] The purpose of this invention is to provide a nozzle limiting protection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a suction nozzle limiting protection device, comprising an air pipe connector and an air guide rod, wherein the air pipe connector and the air guide rod are slidably connected, the air guide rod is connected to the suction nozzle rod, the suction nozzle rod is nested on a limiting block, and the lower end of the limiting block is fixed with a support foot at an equal angle.

[0005] Preferably, the outer side of the upper end of the air guide rod forms a sealing mechanism with the inner wall of the air pipe connector through a silicone sealing ring. The silicone sealing between the air guide rod and the air pipe connector can prevent air leakage when the air guide rod slides, thereby ensuring the normal operation of the device.

[0006] Preferably, a circular plate is also fixed on the air guide rod, and the circular plate is fixed on the limiting block. Through the above structure, the stability of the device installation can be guaranteed.

[0007] Preferably, a silicone nozzle is fixed at the lower end of the suction rod, and the silicone nozzle is located below the limiting block. The lower end face of the silicone nozzle is lower than the lower end face of the support foot. The silicone nozzle can achieve the adsorption of soft material components, and by limiting the position of the silicone nozzle, the normal mounting of soft material components can be facilitated.

[0008] Preferably, one end of the spring is fixed on the circular plate, and the other end of the spring is fixed on the air pipe connector. The spring can provide a basic force for the reset of the circular plate and the air guide rod.

[0009] Preferably, the support foot is provided with four feet, and the side of the support foot near the silicone nozzle has an inclined structure. The support foot contacts the workpiece. Through the function of the support foot, a positioning function can be achieved, thereby controlling the stroke and pressure and avoiding damage to soft material components during the mounting process.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This nozzle limiting protection device is designed and installed on the nozzle based on the component height and mounting force requirements. In actual use, when a soft component contacts the target component and continues to press down until the limiting device reaches the target component, the nozzle rod continues to press down. Under the action of the limiting device, the soft component will not increase its downward stroke and force, ensuring that the bonding pressure between the component and the target component is relatively constant and protecting the component.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 This utility model provides a technical solution: a suction nozzle limiting protection device, including an air pipe connector 1 and an air guide rod 2. The air pipe connector 1 and the air guide rod 2 are slidably connected. The air guide rod 2 is connected to the suction nozzle rod 3. The suction nozzle rod 3 is nested on the limiting block 6. The lower end of the limiting block 6 is fixed with a support foot 601 at an equal angle.

[0017] The upper outer side of the air guide rod 2 forms a sealing mechanism with the inner wall of the air pipe connector 1 through a silicone sealing ring; a circular plate 4 is also fixed on the air guide rod 2, and the circular plate 4 is fixed on the limiting block 6; a silicone suction nozzle 301 is fixed at the lower end of the suction rod 3, and the silicone suction nozzle 301 is located below the limiting block 6, and the lower end face of the silicone suction nozzle 301 is lower than the lower end face of the support leg 601; one end of the spring 5 is fixed on the circular plate 4, and the other end of the spring 5 is fixed on the air pipe connector 1; four support legs 601 are provided, and the side of the support leg 601 near the silicone suction nozzle 301 is a sloping structure, and the support leg 601 is in contact with the workpiece 7;

[0018] When using this suction nozzle limit protection device, such as Figures 1-3 As shown, firstly, the air pipe connector 1 is installed on the driving component (cylinder or other driving component), and the air pipe connector 1 is connected to the vacuum adsorption pump through a conduit. In actual use, the silicone nozzle 301 can be used to adsorb soft material components, and the moving component moves the soft material components to the mounting position. Then, the driving device moves the air pipe connector 1 down, thereby driving the silicone nozzle 301 and the soft material components down. When the soft material components contact the workpiece 7, the support leg 601 is in a suspended state, and the driving device... Continue to move the air pipe connector 1 downwards until the support leg 601 contacts the workpiece 7 to achieve the limiting effect. At this time, the air pipe connector 1 continues to be pressed down, causing the air guide rod 2 to slide upwards inside the air pipe connector 1, ensuring the normal operation of the device. At this time, due to the limiting effect of the support leg 601, the soft material component will not increase the downward stroke and force. This can ensure that the bonding pressure of the soft material component is constant and avoid the problem of damage to the soft material component due to excessive bonding pressure. This is the working principle of the suction nozzle limiting protection device.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
