Description

Technical Field

[0001] The present invention relates to the technical field of microchannel plates, and in particular to a packaging device and method for packaging multiple microchannel plates. Background Art

[0002] A microchannel plate (MCP) is a microporous optical element with millions of microporous electron multiplier devices in a parallel array. It is a two-dimensional vacuum electron multiplier with a thin sheet structure. It is sensitive to electrons, ions and accelerated neutral particles, ultraviolet photons and X-rays. It is widely used in image intensifiers, displays, space science, medical testing, dangerous goods / contraband detection, and analytical instruments.

[0003] The conventional microchannel plate preparation process relies on glass multi-fiber drawing technology (GMD). The lead silicate skin glass tube and the corresponding core material rod are prepared and drawn into single fiber filaments at high temperature. After a series of processes such as drawing multiple fibers, arranging screens, melting and pressing, cold processing, corrosion, hydrogen reduction, and coating, a multi-channel array-type thin film is manufactured. After surface inspection and electrical performance testing, the qualified finished products are finally packaged, stored, and transported to the user for assembly and use, such as assembly into image intensifiers.

[0004] The microchannel plate is a precision optical element. In order to reduce the contamination of the thin film surface (such as dust, particles, water vapor, etc.) during storage and transportation, and to reduce the wear or damage caused by bumps and shaking, the traditional microchannel plate packaging box adopts a single-piece packaging structure, which mainly includes a box bottom, a box cover and a fixing strip. In the process of fixing and packaging the microchannel plate, the finished microchannel plate is placed horizontally in the arc groove of the box bottom, and then the convex surface of the box cover is facing downward and pressed on the outermost edge of the microchannel plate. After the box cover is closed, the box bottom and the box cover are fixed with a fixing strip.

[0005] In order to reduce shaking and collision during transportation, a spring structure is also used for compression, for example, a spring upper claw is installed in the bottom of the box, and a spring lower claw is installed in the box cover. The above-mentioned arc groove is set inside the spring structure for placing the microchannel plate. During the packaging process, the specific operations are as follows: 1. Fix the spring lower claw to the bottom of the box, and place the finished microchannel plate horizontally in the concave arc of the spring lower claw; 2. Press the convex surface of the spring upper claw downward on the outermost edge of the microchannel plate; 3. Cover the box cover, press the real spring upper claw completely down to the inside of the box bottom, and then use the fixing strip to fix the box bottom and the box cover. 4. Put the fixed packaging box and a specific desiccant together into an anti-static shielding bag and vacuum it for storage. In the above packaging process, especially step 3, the process of pressing the spring upper claw down to the inside of the box bottom will rub the outermost edge of the microchannel plate in contact with the upper claw, thereby generating dust particles and contaminating the surface of the microchannel plate. At the same time, since traditional packaging boxes are manufactured through mold stamping, the processing accuracy is poor, resulting in 10% of the spring upper claws not being pressed down to the inner side of the box bottom when the upper claws are pressed down to the lowest end through the box cover. The packaged microchannel plate is not completely fixed during transportation and keeps shaking, causing the edges of the microchannel plate to be broken, worn, and contaminated by particles, seriously affecting the surface cleanliness.

[0006] With the continuous expansion and deepening of the application of microchannel plates in the fields of image intensifiers, space science, medical testing, and analytical instruments, especially the sharp increase in demand for microchannel plates used in low-light image intensifiers and analytical instruments, the annual demand has reached more than hundreds of thousands of pieces.

[0027] Compared with the prior art, the packaging device and packaging method for packaging multiple microchannel plates of the present invention have the following significant advantages:

[0028] 1. For the packaging of batches and multiple microchannel plates, under the premise of ensuring the protection of the microchannel plates and the surface cleanliness requirements, the packaging production efficiency of the finished microchannel plates is significantly improved through the interlocking and pressing of the base and the upper cover and the sealing of the inside and the outside, and the shock absorption effect and sealing effect of the finished microchannel plates when they encounter impact and vibration during packaging and transportation are improved, ensuring the surface cleanliness of the effective area of ​​the microchannel plates;

[0029] 2. The overall protrusion of the base and the concave design of the installation area are used, which cooperates with the overall concave design of the upper cover and the protrusion design of the embedded matching area to form a double tight fit and sealing effect between the inner and outer layers, reducing and avoiding damage to the microchannel plate caused by vibration and impact during storage and transportation, and ensuring the effect of tight fit and compression, preventing the risk of wear and cracking of the edge solid area caused by shaking during transportation;

[0030] 3. The entire packaging process does not involve the compression and installation operations of springs, claws and other components, which reduces possible damage to the surface of the microchannel plate sheet and reduces glass particle contaminants introduced by the friction of the physical edge during the traditional dynamic compression process. At the same time, during the packaging process, only the physical edge contacts the upper and lower covers of the packaging box, which improves the quality and surface cleanliness of the finished microchannel plate.

[0031] 4. A gradual bell-mouth shape is set at the matching entrance position of the embedded clamping structure to reduce the sharp edge structure and facilitate the guidance for rapid embedding and matching;

[0032] 5. The circular placement groove of the base, the compacting fitting space and the embedded part inside the upper cover are designed to form a shape and position coordination, which can support the board picking requirements of different users in the same packaging box, including the use of tweezers, three-claw picking tools and suction cups. Three different user needs avoid the complex design of a separate picking structure and greatly reduce the overall weight of the packaging box.

[0052] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0053] Various aspects of the present invention are described in this disclosure with reference to the accompanying drawings, in which many illustrative embodiments are shown. The embodiments of the present disclosure are not necessarily intended to include all aspects of the present invention. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed by the present invention are not limited to any implementation. In addition, some aspects disclosed by the present invention can be used alone or in any appropriate combination with other aspects disclosed by the present invention.

[0054] {Example 1}

[0055] Combination Figures 1 to 13 In the example shown, the packaging device for packaging multiple microchannel plates according to an embodiment of the present invention includes a base 100 for carrying multiple microchannel plates 200 and an upper cover 300 that presses the base 100 and closes the microchannel plate accommodating area.

[0056] Combination Figure 6 , 7 As shown, the microchannel plate 200 as an example is in the shape of a circular thin sheet, and is composed of an active area 200A and a solid area 200B surrounding the edge of the active area 200A.

[0057] Combination Figure 2 , 3 as well as Figure 6 As shown, a protrusion 110 of a predetermined shape is provided on one side surface of the base 100 to form a microchannel plate accommodating area.

[0058] like Figure 2 , 3 In the example shown, the microchannel plate accommodating area is provided with a plurality of circular grooves 111 for placing the microchannel plate 200 and forming a bottom support for it. The circular groove 111 is composed of a first groove 111A extending along one side surface toward the other side surface of the base 100 and a second groove 111B connected to the first groove 111A; the diameter D1 of the first groove 111A is greater than the diameter D2 of the second groove 111B.

[0059] For ease of explanation, Figure 2 In the example shown, 100A represents a first surface of the base, 100B represents a second surface of the base, and the circular groove 111 extends toward the first surface of the base and goes deeper along the thickness direction.

[0060] Therefore, through the aforementioned design of grooves of different diameters, a step surface is formed at the connecting position between the first groove and the second groove, especially a step surface with a certain inclination angle, for example, designed as an arc chamfer or a C-shaped chamfer, which is conducive to the assembly and compression of the microchannel plate and has a certain size adaptability.

[0061] As shown in the accompanying drawings, the circular groove 111 is provided with a plurality of ear grooves along its circumferential direction, each ear groove is connected to the circular groove 111, and the ear grooves of any two adjacent circular grooves 111 along the transverse and / or longitudinal direction are connected, forming a compression and fitting space when the upper cover 300 is closed.

[0062] like Figures 1 to 3 as well as Figure 5 In the example shown, with the central axis O1 of the base as the boundary, along the longitudinal X direction and the Y direction perpendicular to the X direction, multiple circular grooves 111 are arranged in a matrix of M*N, in 2 rows and 5 columns, with a total of 10 packaging positions for placing microchannel plates, and 10 finished microchannel plates can be packaged at one time.

[0063] In order to facilitate the alignment of the base and the upper cover, the circular groove 111 at each position (i.e., the placement position) is numbered, such as Figure 1 , 6 As shown, Arabic numerals 1, 2, 3, ..., 10 are marked on the corresponding positions of the base and the upper cover to indicate different position numbers.

[0064] In a preferred embodiment, a plurality of ear grooves are arranged at an angle of 120° in the circumferential direction. As shown in the figure, the three ear grooves are evenly distributed in the circular direction and are all connected to the circular groove 111. Therefore, in any circular groove 111 where the microchannel plate is placed, different user's picking methods can be supported, such as sucking by a suction cup on the surface of the microchannel plate sheet, or picking up by tweezers from any ear groove position to grab the physical edge of the microchannel plate, or grabbing from three ear groove positions by a three-claw tool, so as to meet different picking requirements and no additional complex picking structure design is required.

[0065] In a preferred embodiment, in the microchannel plate accommodating area, any two adjacent circular grooves 111 have at least two ear grooves correspondingly connected to each other.

[0066] like Figure 3 , Figure 6 As shown, for the circular groove 111 located at the edge position, such as the circular groove 111 at the four corner positions, the three ear grooves configured therein include an edge ear groove 113 located at the edge, a second ear groove 114 located in the X direction, and a third ear groove 115 located in the Y direction, wherein the second ear groove 114 and the third ear groove 115 are respectively connected to the second ear groove 114 and the third ear groove 115 corresponding to the adjacent circular groove 111 in the X direction and the Y direction, to form the aforementioned pressed and fitted space.

[0067] like Figure 3 , Figure 6 As shown, for the circular grooves 111 at other positions, the three ear grooves configured therein include two second ear grooves 114 along the X direction and a third ear groove 115 located in the Y direction. Similarly, as shown in the figure, the two second ear grooves 114 located in the X direction are respectively connected with the second ear grooves 114 located in the X direction of the adjacent circular grooves 111, and the third ear groove 115 located in the Y direction is connected with the third ear groove 115 located in the Y direction of the adjacent circular groove 111, forming the aforementioned pressed fitting space.

[0068] Combined with Figure 3 As shown, for ease of understanding, a pair of adjacent circular grooves 111 are divided and displayed along the Y direction by a dividing line O2.

[0069] like Figures 7 to 11 In the example shown, a groove portion 310 is formed on a surface of the upper cover 300 facing the base 100 , the groove portion 310 being matched with the protrusion portion 110 in shape and position.

[0070] Combination Fig.10 as well as Figure 1 , Figure 6 As shown, the groove portion 310 is provided with an embedding portion that matches the shape and position of the compression and embedding space.

[0071] The embedded portion protrudes from the surface of the groove portion 310 .

[0072] As an optional embodiment, in the microchannel plate accommodating area, each circular groove 111 located at the edge has at least one ear groove that is not connected to the adjacent circular groove 111, that is, the edge ear groove 113. Accordingly, an independent embedding portion is provided in the groove portion 310 of the upper cover 300 to be embedded and pressed therewith, such as Figure 8 , Fig.10 As shown, the shape and position of the edge embedding portion 313 and the edge ear groove 113 are independently adapted.

[0073] Combined diagram Figures 8 to 10 As shown, the embedded portion designed for the groove portion 310 of the upper cover includes an edge embedded portion 313 that matches the position and shape of the edge ear groove 113, a first embedded portion 311 that matches the position and shape of the second ear groove 114 in the X direction, and a second embedded portion 312 that matches the position and shape of the third ear groove 115 in the Y direction.

[0074] It should be understood that the first embedded portion 311 is matched with a pair of second ear grooves 114 that are communicated with each other, and the second embedded portion 312 is matched with a pair of third ear grooves 115 that are communicated with each other.

[0075] Combination Figures 2-3 , Figure 5 , Figure 6 as well as Figures 9 to 12 As shown, in the design of the embedded part, a first arc portion 311A ​​with a first diameter and a second arc portion 311B connected to the first arc portion 311A ​​and having a second diameter are sequentially formed on the edge in the direction of pressing into the compression fitting space. The first diameter is set to D1 and the second diameter is directly set to D2.

[0076] Thus, after the microchannel plate 200 is loaded into the circular groove 111 of the base 100 and supported by the second groove 111B, when the upper cover 300 is pressed against the base 100, the embedding portion is embedded into the compressed and embedded space of the base 100, and the circular groove 111 is closed by the cooperation of the first arc portion 311A ​​and the first groove 111A, and the microchannel plate 200 supported by the second groove 111B is pressed by the cooperation of the second arc portion 311B and the second arc portion 311B, and the second arc portion 311B is pressed against the edge of the microchannel plate 200.

[0077] Combination Figure 5 , Fig.12 as well as Figure 6 , Figure 7 As shown, the solid area 200B of the microchannel plate 200 is located at the connection position between the first groove 111A and the second groove 111B and is supported by the edge portion formed by the second groove 111B.

[0078] The second arc portion 311B of the embedded portion is pressed against the solid area 200B of the microchannel plate 200 and does not contact the active area 200A of the microchannel plate 200 .

[0079] As a preferred embodiment, Fig. 9 and Fig.10 In the example shown, the embedded portion of the groove portion 310 is provided with the first arc portion 311A ​​and the second arc portion 311B only in the direction of the position where it contacts the microchannel plate 200, and is provided to form a shape match along the thickness direction with the edge of the pressed fitting space in the direction of the position where it does not contact the microchannel plate 200. In the illustrated method, a smooth surface vertical fit along the thickness direction is adopted.

[0080] As a preferred embodiment, the circular groove 111 on the base 100, the ear groove, and the embedded portion on the upper cover 300 all form a first C-shaped chamfer 112A at the entrance edge position where they are embedded and matched with each other, presenting a gradual trumpet shape, gradually narrowing from the outside to the inside.

[0081] As a preferred embodiment, the connection between the first groove 111A and the second groove 111B is configured to form a second C-shaped chamfer 112B, which is in a gradual trumpet shape and gradually narrows from the outside to the inside.

[0082] It should be understood that the size of the first C-shaped chamfer is greater than the size of the second C-shaped chamfer.

[0083] As a preferred embodiment, the edge of the protruding portion 110 of the base 100 and the edge of the groove portion 310 of the upper cover 300 are both chamfered.

[0084] As a preferred embodiment, a first hole position 150 is provided on at least one pair of edges of the raised portion 110 of the base 100, and a second hole position 350 corresponding to the first hole position 150 is provided on the corresponding edge of the groove portion 310 of the upper cover, and the fastener 400 passes through the second hole position 350 and is tightened to the first hole position 150 of the base 100, thereby completing the fastening and fixation of the two.

[0085] The aforementioned fastener 400 can be, in particular, a high-head screw or a high-head bolt that can be tightened manually or with a tool.

[0086] As a preferred embodiment, the base 100 and the upper cover 300 are both made of aluminum alloy material, which is lightweight and can form an oxide film through surface hard oxidation treatment to improve wear resistance and durability.

[0087] As an optional embodiment, the distance between the upper and lower surfaces of the microchannel plate 200 and the packaging box is 0.02 mm to 0.05 mm.

[0088] {Example 2}

[0091] Step 2, cover the upper cover: according to the shape and position adaptation of the embedding portion of the upper cover 300 and the pressing and fitting space of the base 100, the upper cover 300 is pressed onto the base 100 and the embedding portion is embedded into the pressing and fitting space of the base 100, the circular groove 111 is closed by the cooperation of the first arc portion 311A ​​and the first groove 111A, and the microchannel plate 200 supported by the second groove 111B is pressed by the cooperation of the second arc portion 311B and the second groove 111B, so that the second arc portion 311B is pressed on the solid area 200B at the edge of the microchannel plate 200, forming a closed fitting of the internal accommodating area; and the external closed fitting is formed by the embedding and fitting of the protruding portion 110 of the base 100 and the groove portion 310 of the upper cover 300;

[0092] Step 3, fixing the packaging box: Use a fastener to pass through the upper cover 300 and tighten it to the edge of the base 100, so as to fix the base 100 and the upper cover 300 to form an integrated packaging box;
