Description

Technical Field

[0001] This utility model relates to the field of instrument accessory bonding technology, specifically to a nozzle bonding fixture. Background Technology

[0002] Microcrystalline glass is commonly used in high-precision instruments (such as vacuum chambers, optical equipment, and semiconductor manufacturing devices) or chemical reactors. Because microcrystalline glass itself is impermeable to air, it is usually necessary to attach gas nozzles to its sidewalls to inject inert gases (such as nitrogen or argon) or expel harmful gases. Depending on the specific structure, the location of the gas nozzles is usually strictly defined (the nozzle location affects the optimization of the airflow path and avoids direct impact on sensitive components). Therefore, accurately and firmly attaching the target gas nozzle to the target location on the microcrystalline glass is crucial. Existing auxiliary bonding tools are either too expensive or difficult to stably clamp the target gas nozzle (a circular object) without touching the bonding surface and accurately deliver it to the target position.

[0025] Example 1

[0026] An embodiment provides a nozzle bonding fixture, such as Figure 1As shown, the nozzle bonding fixture includes a nozzle fixing assembly for fixing the target nozzle 100 and a positioning and moving mechanism 1 for moving the target nozzle 100 to a preset position; the nozzle fixing assembly includes a mounting part 2 for fixing the target nozzle 100 and a connecting fixing plate 3 for fixing the mounting part 2, and the connecting fixing plate 3 is fixedly connected to the positioning and moving mechanism 1. Specifically, the positioning and moving mechanism 1 is a six-dimensional stage, and the connecting fixing plate 3 is fixedly connected to the displacement stage of the six-dimensional stage via a lead screw. Figure 1 As shown, the mounting component 2 is cylindrical, and an adaptation groove 21 adapted to the shape of the target nozzle 100 is formed on one end face of the mounting component 2. The target nozzle 100 may be made of rigid or flexible material. For flexible target nozzles 100, fixing them can easily cause deformation. In a deformed state, it is not conducive to the application of adhesive on the bonding surface and the bonding between the target nozzle 100 and the target microcrystalline glass. In this embodiment, by setting an adaptation groove 21 on the mounting component 2 that adapts to the shape of the target nozzle 100, the movement of the target nozzle 100 can be restricted, deformation of the target nozzle 100 can be avoided, and the bonding surface of the target nozzle 100 can be prevented from being touched. After the target nozzle 100 and the target microcrystalline glass are bonded, it is only necessary to control the mounting component 2 to move away from the target nozzle 100 along the axial direction of the target nozzle 100, making disconnection convenient and quick.

[0027] Furthermore, before bonding, the positioning and moving mechanism 1 needs to drive the mounting part 2 to adjust its position and find the preset position (target bonding position). In this process, although the target nozzle 100 can be prevented from moving away from the adapter groove 21 along the axis by controlling the displacement speed, it will prolong the bonding time of the target nozzle 100 and affect the bonding efficiency. Therefore, a small amount of adhesive material with low adhesion strength, such as double-sided tape, can be applied between the inner wall of the adapter groove 21 and the target nozzle 100 to temporarily fix the target nozzle 100.

[0028] To prevent displacement of the mounting component 2 during the bonding process of the target air nozzle 100, preferably, the connecting fixing plate 3 includes a plate body 31, on which a fixing platform 32 protruding from the plate body 31 is provided. The fixing platform 32 has a fixing groove 321 for accommodating the mounting component 2. The air nozzle fixing assembly also includes a fastener 4. A through hole is provided in the fixing platform 32 to connect the fixing groove 321 to the outside. The through hole is adapted to the fastener 4, and the fastener 4 can pass through the through hole and abut against the mounting component 2. Through the cooperation of the fastener 4 and the fixing groove 321, the mounting component 2 can be fixed between the fastener 4 and the inner wall of the fixing groove 321. For example, the fastener 4 is a bolt, and the through hole is a screw hole. To facilitate the fastener 4 in fixing the mounting component 2 and to increase the friction between the mounting component 2 and the fixing groove 321, the mounting component 2 is prismatic, specifically an N-prism, where N is an even number, to ensure that the prism contains at least one pair of parallel sides. Furthermore, by controlling the length of the bolt screw-in ( Figure 1 The length of the downward rotation is in the middle. The fixing groove 321 can adapt to different sizes (cross-sectional area) of the mounting parts 2 within a certain range, thereby meeting the adaptation requirements of different sizes of target nozzles 100.

[0029] Furthermore, the main body 31 and the fixing platform 32 are integrally formed. This improves the overall stability of the connecting fixing plate 3 and reduces the manufacturing process and cost of the connecting fixing plate 3.

[0030] Example 2

[0031] This embodiment provides another solution to prevent the target nozzle 100 from moving axially at the bonding front. Specifically, an adapter groove 21 adapted to the shape of the target nozzle 100 is provided on the end face of one end of the mounting member 2, and a first vent hole communicating with the adapter groove 21 is also provided on the mounting member 2; Figure 2 As shown, a second vent 322 is provided on the inner side wall of the fixing groove 321, and a first connecting hole is provided on the side wall of the fixing platform 32 for connecting the second vent 322 with the outside. The first connecting hole is connected to the vacuum negative pressure pump through the first pipe 5. When the mounting part 2 is fixed between the fastener 4 and the inner side wall of the fixing groove 321, the first vent and the second vent 322 are connected.

[0032] Specifically, before bonding the target nozzle 100, a vacuum negative pressure pump can be used to continuously provide negative pressure to the adapter groove 21, adsorbing the mounting part 2 into the adapter groove 21. Since the adapter groove 21 is adapted to the shape of the target nozzle 100, deformation of the flexible material target nozzle 100 can be effectively avoided. Since the nozzle is usually lightweight, the vacuum negative pressure pump can be a commonly available micro vacuum negative pressure pump (such as the XZ miniature vacuum pump).

[0033] Considering that the connection between the target air nozzle 100 and the mounting part 2 needs to be released as soon as possible after the bonding is completed to improve efficiency, this embodiment also provides a second connecting hole on the side wall of the fixed platform 32, which can connect the second vent hole 322 to the outside. The second connecting hole is connected to the air pressure valve 7 through the second pipe 6. That is, after the bonding is completed, the vacuum negative pressure pump is turned off, and the air pressure valve 7 is turned on to allow the first vent hole to connect to the outside through the second vent hole 322, the second connecting hole, and the second pipe 6, so as to quickly balance the air pressure in the adapter groove 21, release the adsorption state of the mounting part 2, and allow the mounting part 2 to smoothly move away from the target air nozzle 100 along the axial direction of the target air nozzle 100 without affecting the bonding state between the target air nozzle 100 and the target microcrystalline glass.
