Description

Technical Field

[0001] The utility model belongs to the technical field of vapor deposition machines, and in particular relates to a sampling sleeve. Background Art

[0002] A vacuum evaporation machine is a device that vaporizes coating materials (such as metals, metal alloys or compounds) by heating and evaporating them under vacuum conditions, and deposits them on the surface of a substrate to form a thin film. It is mainly composed of a vacuum pumping system and an evaporation chamber. The vacuum pumping system consists of a high vacuum pump, a low vacuum pump, exhaust pipes and valves, etc., and the evaporation chamber is used to place substrates and evaporation materials. The vacuum evaporation machine has the advantages of simple film forming method, high film purity and density, and unique film structure and performance. Therefore, it is widely used in the field of film preparation for plastics, metals, ceramics and other products. Its product application range covers electronic products, decoration and decorative products, handicrafts and packaging supplies.

[0003] When the vacuum evaporation machine is in use, a crystal oscillator probe is needed to detect the thickness of the coating film of the coated workpiece. However, since the crystal oscillator is not equipped with a protective mechanism, the crystal oscillator contacts the vacuum evaporation chamber during the detection, and the surface of the crystal oscillator will be coated with a coating. This requires the staff to replace the crystal oscillator in time, otherwise it will affect the normal use of the crystal oscillator probe, and thus easily reduce the service life of the crystal oscillator, and at the same time increase the workload of the staff to replace the crystal oscillator.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a sampling sleeve.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0006] The utility model aims to provide a sampling sleeve, which can solve the problem that a crystal oscillator is easily coated due to lack of protection.

An adjustable sampling sleeve is installed on the shell, and the adjustable sampling sleeve corresponds to a pair of crystal oscillators.

[0011] In one or more embodiments of the utility model, an adjustment groove is drilled on the shell to accommodate a sampling protection sleeve so that the crystal oscillator can measure the thickness of the coating film layer of the coated workpiece.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] like Figures 1 to 5 As shown, a sampling sleeve in an embodiment of the utility model includes a crystal oscillator probe body 1 and a protection mechanism 2.

[0031] A pair of crystal oscillators 101 are mounted on the crystal oscillator probe body 1, and the crystal oscillator 101 is used to detect the thickness of the coating film of the coated workpiece. A slide groove 102 is provided on the side wall of the crystal oscillator probe body 1, and the slide groove 102 is used to accommodate the protrusion 202, so as to realize the installation and fixation of the protection mechanism 2.

[0032] Preferably, the crystal oscillator probe body 1 and the crystal oscillator plate 101 used in the present application are both prior art, and the connection between the crystal oscillator probe body 1 and the crystal oscillator plate 101 is also prior art, so their connection and working principle will not be described in detail here.

[0033] like Figures 1 to 5 As shown, the protection mechanism 2 is installed on the crystal oscillator probe body 1. The protection mechanism 2 is used to protect the crystal oscillator 101 and reduce the probability of the crystal oscillator 101 being coated. It can not only ensure the service life of the crystal oscillator 101, but also reduce the frequency of the staff replacing the crystal oscillator 101, and to a certain extent, it can also reduce the workload of the staff in replacing the crystal oscillator 101.

[0034] The protection mechanism 2 includes a housing 201, a protrusion 202 is connected to the housing 201, and the protrusion 202 is slidably arranged in the slide groove 102. The protection mechanism 2 can be installed with the crystal oscillator probe body 1 by sliding the protrusion 202 in the slide groove 102, which is convenient for operation.

[0035] In addition, an adjustment groove 203 is bored on the housing 201 to accommodate a sampling protection sleeve 204 so that the crystal oscillator 101 can measure the thickness of the coating film of the coated workpiece.

[0036] like Figures 1 to 5 As shown, an adjustable sampling sleeve is installed on the housing 201, and the adjustable sampling sleeve corresponds to a pair of crystal oscillators 101. The adjustable sampling sleeve can protect the crystal oscillator 101, reduce the probability of the crystal oscillator 101 being coated, and thus ensure the normal service life of the crystal oscillator 101.

[0037] The adjustable sampling sleeve includes a pair of sampling protection sleeves 204, which are slidably disposed in the adjustment slot 203, and the pair of sampling protection sleeves 204 respectively correspond to a pair of crystal oscillators 101. The sampling protection sleeves 204 are used to protect the crystal oscillator 101, reduce the probability of the crystal oscillator 101 being coated, and thus reduce the replacement frequency of the crystal oscillator 101, thereby ensuring the service life of the crystal oscillator 101.

[0038] In addition, an outer frame 205 is provided on the outside of the sampling protection sleeve 204 . The outer frame 205 is fixedly connected to the housing 201 . The outer frame 205 is used to fix the sampling protection sleeve 204 and further protect the crystal oscillator 101 .

[0039] Specifically, an adjustment cavity is provided in the outer frame 205 , and a bidirectional screw 206 is rotatably connected in the adjustment cavity. One end of the bidirectional screw 206 is provided outside the outer shell 201 , so that the staff can rotate the bidirectional screw 206 conveniently.

[0040] In addition, a connector 207 is fixedly connected to the sampling protection sleeve 204, and the connector 207 is threadedly connected to the bidirectional screw 206. When the bidirectional screw 206 rotates, the connector 207 is moved by the thread, thereby adjusting the position of the sampling protection sleeve 204 in the adjustment slot 203, so that the protection mechanism 2 as a whole can be suitable for different models of crystal oscillator probe bodies 1, thereby expanding the application range of the protection mechanism 2 as a whole.

[0041] Furthermore, a avoidance groove is cut on the side wall of the housing 201, the avoidance groove is communicated with the adjustment cavity, and the connecting member 207 is slidably disposed in the avoidance groove.

[0042] like Figures 1 to 5 As shown, a limiter 208 is installed in the adjustment cavity, and the limiter 208 is arranged in the middle of the adjustment cavity. The limiter 208 is used to limit the moving distance of the connector 207, so that the pair of sampling protection sleeves 204 are not easy to collide during adjustment, thereby ensuring the safety of the adjustment of the sampling protection sleeves 204.

[0043] The bidirectional screw rod 206 passes through the limiting member 208 and is rotationally connected to the limiting member 208 .

[0044] In addition, an elastic member 209 is connected to the port of the housing 201 , and a pair of sampling protection sleeves 204 pass through the elastic member 209 . The elastic member 209 can protect the crystal oscillator 101 , further reducing the probability of the crystal oscillator 101 being coated, and can also protect the bidirectional screw 206 and the connector 207 .

[0045] Preferably, the elastic member 209 is made of rubber material, which is not only elastic but also resistant to high temperatures, and is not likely to affect the sliding of the sampling protection sleeve 204, while also having a good protective effect.

[0046] During specific use, the protrusion 202 is slidably installed in the slide groove 102 to achieve installation and fixation of the protection mechanism 2.

[0047] Then, the distance between the pair of sampling protection sleeves 204 is adjusted according to the distance between the pair of crystal oscillators 101. When adjusting the sampling protection sleeves 204, it is only necessary to rotate the bidirectional screw 206. When the bidirectional screw 206 rotates, the connecting member 207 is driven by the thread to move the sampling protection sleeves 204 in the adjustment slot 203. Since the bidirectional screw 206 is a bidirectional thread, the pair of sampling protection sleeves 204 will move in opposite directions until the sampling protection sleeves 204 are concentric with the crystal oscillator 101, and then the rotation of the bidirectional screw 206 can be stopped.

[0048] The present application can increase the protection effect of the crystal oscillator 101 by setting the outer shell 201, the sampling protection sleeve 204 and the elastic member 209, thereby reducing the probability of the crystal oscillator 101 being coated, ensuring the service life of the crystal oscillator 101, and also reducing the frequency of staff replacing the crystal oscillator 101, reducing the staff's workload, and alleviating the staff's burden to a certain extent.
