Technical Field
[0001] The utility model relates to the field of gas sensor processing, in particular to gas sensor processing equipment which can conveniently adjust deposition thickness. Background Art
[0002] Gas sensors are used to detect gas concentration and composition, and they play an extremely important role in environmental protection and safety supervision.
[0003] The raw materials for gas-sensitive sensors include single-crystal alumina substrates. During production, an oriented single-crystal alumina substrate with a side length of 10 mm needs to be ultrasonically cleaned in acetone, isopropyl alcohol, and deionized water for 5 minutes in sequence. The substrate is then blown dry with ultra-clean synthetic air, and the polished surface of the substrate is checked under an optical microscope to see if it is clean. Otherwise, subsequent processing will be required.
[0004] Since the single crystal alumina substrate is small in size, it is easy for the single crystal alumina substrate to roll and collide when placed directly in an ultrasonic cleaning machine, resulting in damage to the single crystal alumina substrate.
[0005] Therefore, it is necessary to propose a new gas sensor processing equipment that can easily adjust the deposition thickness to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a gas sensor processing equipment with convenient adjustment of deposition thickness, so as to solve the problem that the single crystal alumina substrate is small in size and is easily caused to roll and collide when placed directly in an ultrasonic cleaning machine, resulting in damage to the single crystal alumina substrate.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a gas sensor processing equipment that is convenient for adjusting the deposition thickness, including an ultrasonic cleaning machine, a cleaning tank is provided on the ultrasonic cleaning machine, a placement basket is provided inside the cleaning tank, and a fixed drying mechanism is placed inside the placement basket.
[0008] The fixed drying mechanism includes a base plate, support blocks are fixed on both sides of the top of the base plate, two fixed tubes are provided on the top of the two support blocks, air grooves are opened on the opposite sides of the two support blocks, the bottom ends of the two fixed tubes are connected to the corresponding air grooves, a lower pressure plate is slidably provided on the fixed tubes, an air box for inputting ultra-clean synthetic air is fixed on the ultrasonic cleaning machine, a hose is provided on one side of the air box, and one end of the hose is connected to the corresponding fixed tube.
[0009] Preferably, two gas boxes are provided, and the two gas boxes are connected by a pipeline. The bottom end of the hose is provided with a threaded opening, and the threaded opening is threadedly connected to the fixed pipe.
[0010] Preferably, support handles are fixed to the top ends of both sides of the placement basket, and the two support handles are supported on the top ends of both sides of the cleaning tank.
[0011] Preferably, an auxiliary handle is fixedly connected to the top of the lower pressure plate, and an input port is provided on one side of the air box.
[0012] Preferably, an ultrasonic generator is provided inside the ultrasonic cleaning machine, and the ultrasonic generator is located at the bottom end of the cleaning tank, and a cleaning liquid is provided inside the cleaning tank.
[0013] Preferably, the outer sides of the placement baskets are all provided with filter structures.
[0014] Preferably, a solenoid valve is provided at the connection between the input port and the corresponding gas box.
[0015] The beneficial technical effects of the present utility model are:
[0016] The lower pressure plate is lifted up by the auxiliary handle, and the single crystal alumina substrate is placed on the bottom plate. The lower pressure plate is released, and the lower pressure plate automatically presses down and fixes the single crystal alumina substrate. When the fixed drying mechanism is placed in the cleaning liquid, ultrasonic cleaning will not cause the single crystal alumina substrate to roll over, resulting in collisions between the single crystal alumina substrates and damage.
[0017] At the same time, single crystal alumina substrates can be stacked and placed as needed. According to the thickness of the single crystal alumina substrates, the lower pressure plate can be pressed down and fixed to clean and deposit single crystal alumina substrates of different thicknesses.
[0018] The support block can support the lower pressure plate at a minimum height, leaving space for the cleaning liquid to enter and clean the single crystal alumina substrate, so as to avoid squeezing and damaging the single crystal alumina substrate or the cleaning liquid being unable to enter. At the same time, when the single crystal alumina substrate is cleaned, the personnel pulls the placement basket up and inputs ultra-clean synthetic air through the input port. The ultra-clean synthetic air can be discharged from the wind slot on one side of the support block to dry the cleaned single crystal alumina substrate and reduce the residue of the cleaning liquid. The fixed pipe can be used as an air circulation channel and also as a sliding rod for the lower pressure plate to rise and fall. BRIEF DESCRIPTION OF THE DRAWINGS
