Description

Technical Field

[0001] The embodiments of the present invention belong to the field of experimental device technology, specifically relating to an automatic film-collecting machine and method for perforated collection belts. Background Technology

[0002] Bulk electron microscopy is a technique that uses electron microscopes (including scanning electron microscopes and transmission electron microscopes) to continuously and at high resolution image large-volume samples, especially biological samples, to obtain their three-dimensional structures. Based on sample processing methods, it can be divided into bulk electron microscopy techniques based on focused ion beam surface, in-situ diamond scalpel surface, and automated collection of continuous ultrathin sections. Bulk electron microscopy techniques based on automated collection of continuous ultrathin sections can be further divided into those oriented towards scanning electron microscopy imaging, those oriented towards transmission electron microscopy imaging, and those oriented towards scanning transmission electron microscopy imaging. By using an ultrathin slicer and an automated continuous ultrathin section collector in conjunction, continuous ultrathin sections can be collected sequentially on a collection belt. The collection band for scanning electron microscopy (SEM) imaging is typically a smooth, flexible band of a certain thickness. However, for transmission electron microscopy (TEM) and scanning transmission electron microscopy (STEM) imaging, the collection band must allow the imaging electron beam to penetrate the ultrathin slice sample. Therefore, it has a row of equally spaced small holes at the center of the collection band, and these holes are usually covered with a thin film (typically a 10-150 nm thick support film, such as an organic film) to support the continuously collected ultrathin slices while allowing the electron beam to pass through for transmission imaging. Each small hole usually corresponds to one slice. The film covering each small hole in the collection band must be of uniform thickness and free from defects such as missing sections, breaks, or wrinkles.

[0003] In related technologies, segments of the support membrane are manually retrieved and placed onto a collection belt for drying before use. However, the number of continuous ultrathin slices to be collected is large, ranging from hundreds to tens of thousands. Manually retrieving and covering the membrane from the perforated collection belt consumes a significant amount of manpower, is time-consuming, inefficient, and makes it difficult to guarantee the retrieval and covering of high-quality membranes.

[0010] In some embodiments of the present invention, the automatic film-collecting machine of the perforated collection belt further includes a second camera, which is connected to the output end of the second moving mechanism.

Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0019] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The control method steps, processes, and operations described herein are not construed as requiring them to be performed in a specific order described or illustrated unless the order of execution is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0020] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence.

[0022] like Figures 1 to 6As shown, a first aspect embodiment of the present invention provides an automatic film-collecting machine 100 for perforated collection belts. The automatic film-collecting machine 100 includes: a container 50, a first driving mechanism 10, a perforated collection belt 20, a second driving mechanism 30, and a film carrier assembly 40. Specifically, the top of the container 50 has an opening, and the container 50 contains liquid. The first driving mechanism 10 is driven and connected to the perforated collection belt 20. The first driving mechanism 10 is used to drive the perforated collection belt 20 to move vertically, so that at least a portion of the perforated collection belt 20 moves up and down on the liquid surface, and is also used to wind up the perforated collection belt 20. The second driving mechanism 30 is driven and connected to the film carrier assembly 40. The film carrier assembly 40 is used to load at least two support membranes. The second driving mechanism 30 is used to drive the film carrier assembly 40 to move vertically, so that at least a portion of the support membranes floats on the liquid surface. The first driving mechanism 10 is used to drive the perforated collection belt 20 to move perpendicular to the vertical direction, and / or the second driving mechanism 30 is used to drive the film carrier assembly 40 to move perpendicular to the vertical direction.

[0023] According to an embodiment of the present invention, the perforated collection belt automatic film-retrieving machine 100 firstly drives the perforated collection belt 20 to move in a first direction perpendicular to the vertical direction via a first driving mechanism 10, so that the perforated film-retrieving machine moves to a first film-retrieving position; or a second driving mechanism 30 drives the film carrier assembly 40 to move to the first film-retrieving position; or the first driving mechanism 10 drives the perforated collection belt 20 to move to the first film-retrieving position and the second driving mechanism 30 drives the film carrier assembly 40 to move to the first film-retrieving position. Then, the first driving mechanism 10 drives the perforated collection belt 20 to move along the vertical direction toward the liquid in the container 50, so that a portion of the perforated collection belt 20 is located below the liquid surface, and the length of the perforated collection belt 20 below the liquid surface above the extension arm is slightly longer than the length of the support film to be floated down. The second driving mechanism 30 drives the carrier membrane assembly 40 to move vertically toward the liquid in the container 50. As part of the carrier membrane assembly 40 enters the liquid, the first end of the first support membrane on the carrier membrane assembly 40, near the liquid surface, detaches from the surface of the carrier membrane assembly 40 and floats on the liquid surface. The length and width of the first support membrane are pre-marked on the glass slide 42 with a blade, and are typically integer multiples of the hole spacing of the perforated collection tape 20. For example, in this embodiment, the length is defined as the length of 8 hole spacings, and the width is the same as the width of the perforated collection tape 20. Both the length and width can be adjusted according to actual usage. The first end of the first support membrane contacts the perforated collection belt 20 at the liquid surface, with the contact point of the perforated collection belt 20 precisely between the two holes to prevent the seam from covering the holes and affecting later use. Simultaneously, at the contact point, the other end of the first support membrane remains attached to the glass slide 42, typically adjusted to 1-2 mm, ensuring that the drifting support membrane is aligned with the perforated collection belt 20 and preventing it from drifting completely down and floating aimlessly on the liquid surface. Finally, the first drive mechanism 10 moves vertically upwards until the perforated collection belt 20 is completely positioned above the liquid surface, at which point the first support membrane completely covers the perforated collection belt 20. The perforated collection belt 20 has multiple holes, with both ends of the first support film located at different positions. The end of the first support film is positioned between two adjacent holes on the perforated collection belt 20, and the first end of the first support film connects to the support film retrieved from the previous section of the perforated collection belt 20. Once the retrieval of the first support film is complete, the first driving mechanism 10 drives the perforated collection belt 20 to wind up the eight holes along the take-up reel 13, moving the first support film on the perforated collection belt 20 to other positions to provide a covered portion of the perforated collection belt 20 for the retrieval of the second support film. This process is repeated until all support films on the film carrier assembly 40 are retrieved. The automatic film retrieval machine 100 of this embodiment of the invention, through the first driving mechanism 10 and the second driving mechanism 30, can achieve automated film retrieval, thereby improving retrieval efficiency, ensuring film quality, and saving manpower.

[0024] It should be noted that in this embodiment, the vertical direction refers to the direction of gravity, such as... Figure 4 As shown, the vertical direction is perpendicular to the horizontal plane, and perpendicular to the vertical direction is parallel to the horizontal plane. In this embodiment, the second driving mechanism 30 can drive the membrane carrier assembly 40 to move along the vertical direction, so that the support membrane on the membrane carrier assembly 40 moves up and down on the liquid surface. The second driving mechanism 30 can also drive the membrane carrier assembly 40 to move along a direction perpendicular to the vertical direction, so that the membrane carrier assembly 40 can move parallel to the horizontal plane, so that the different support membranes of the membrane carrier assembly 40 correspond to the positions of the perforated collection belt 20.

[0025] In some embodiments of the present invention, the perforated collection belt automatic film-collecting machine 100 further includes a base plate 80, and the first drive mechanism 10, the second drive mechanism 30 and the container 50 are all disposed on the base plate 80. Specifically, on a plane perpendicular to the vertical direction, the cross-section of the container 50 is a rectangular structure, and the first drive mechanism 10 and the second drive mechanism 30 are respectively located on opposite sides of the container 50 so that the positions of the perforated collection belt 20 and the support film of the film carrier assembly 40 correspond.

[0026] In some embodiments of the present invention, the first driving mechanism 10 includes: a first moving mechanism 11, a second moving mechanism 12 and a winding mechanism 13. The output end of the first moving mechanism 11 is connected to the second moving mechanism 12, the output end of the second moving mechanism 12 is connected to the winding mechanism 13, and the perforated collection belt 20 is disposed on the winding mechanism 13.

[0027] The first moving mechanism 11 is used to drive the second moving mechanism 12 to move along the first direction. When it is necessary to move the perforated collection belt 20 to a certain film-catching position, the first moving mechanism 11 drives the second moving mechanism 12 to move along the first direction. The second moving mechanism 12 drives the winding mechanism 13 to move so that the perforated collection belt 20 on the winding mechanism 13 is aligned with a certain film-catching position. The second moving mechanism 12 is used to drive the winding mechanism 13 to move vertically. When it is necessary to immerse part of the perforated collection tape 20 into the liquid, the second moving mechanism 12 drives the winding mechanism 13 to move vertically toward the bottom of the container 50. The winding mechanism 13 drives the perforated collection tape 20 to move toward the bottom of the container 50 until part of the perforated collection tape 20 enters the liquid, so that the position of the perforated collection tape 20 in contact with the film-collecting section is exactly at the liquid surface, and the perforated collection tape 20 of the film-collecting section is slightly longer than the length of the support film to be collected. The second moving mechanism 12 then stops driving the winding mechanism 13 to move. When it is necessary to move the perforated collection tape 20 to another film-collecting position, the second moving mechanism 12 drives the winding mechanism 13 to move vertically away from the bottom of the container 50 so that the perforated collection tape 20 is completely above the liquid surface. Then, the first moving mechanism 11 controls the second moving mechanism 12 to move along the first direction so that the perforated collection tape 20 is moved to another film-collecting position. The distance between the two film-collecting positions is exactly equal to the distance between two adjacent glass slides 42 on the film carrier plate 41. The winding mechanism 13 is used to wind up the perforated collection tape 20. The winding mechanism 13 winds up part of the perforated collection tape 20 so that the part of the perforated collection tape 20 covered with the support film moves to a position away from the liquid surface.

[0028] The first moving mechanism 11 can be a hydraulic cylinder mechanism, a pneumatic cylinder mechanism, or a lead screw and nut mechanism, and the second moving mechanism 12 can be a hydraulic cylinder mechanism, a pneumatic cylinder mechanism, or a lead screw and nut mechanism. In this embodiment, both the first moving mechanism 11 and the second moving mechanism 12 are lead screw and nut mechanisms.

[0029] Specifically, the first moving mechanism 11 is fixed on the base plate 80. The first moving mechanism 11 includes a first drive motor 111, a first lead screw 112, a first slider 113, and a first slide rail 114. The first drive motor 111 is driven and connected to the first lead screw 112. The first slider 113 is sleeved on the first lead screw 112 and meshes with the first lead screw 112. The first slider 113 cooperates with the first slide rail 114. The first slider 113 is connected to the second moving mechanism 12. The extension direction of the first lead screw 112 is the same as the extension direction of the first slide rail 114. The extension direction of the first lead screw 112 is a first direction, which is perpendicular to the vertical direction, that is, the first direction is on a plane perpendicular to the vertical direction. The first drive motor 111 drives the first lead screw 112 to rotate. The first lead screw 112 drives the first slider 113 to move along the extension direction of the first slide rail 114. The first slider 113 drives the second moving mechanism 12 to move, which in turn drives the winding mechanism 13 and the perforated collection belt 20 to move together along the first direction perpendicular to the vertical direction.

[0030] The second moving mechanism 12 is connected to the first slider 113 of the first moving mechanism 11. The second moving mechanism 12 includes a second drive motor 121, a second lead screw 122, a second slider (not shown in the figure), and a second slide rail 124. The second drive motor 121 is driven and connected to the second lead screw 122. The second slider is sleeved on the second lead screw 122 and meshes with the second lead screw 122. The second slider cooperates with the second slide rail 124 and is connected to the winding mechanism 13. The extension directions of the second lead screw 122 and the second slide rail 124 are the same as the vertical direction. The second drive motor 121 drives the second lead screw 122 to rotate, the second lead screw 122 drives the second slider to move along the extension direction of the second slide rail 124, the second slider drives the winding mechanism 13 to move along the vertical direction, and thus drives the perforated collection belt 20 to move along the vertical direction.

[0031] In some embodiments of the present invention, the second moving mechanism 12 and the winding mechanism 13 are connected by a rotating mechanism 15, which is used to calibrate the angle of the winding mechanism 13 relative to the film carrier assembly 40, so that it faces the film carrier side of the film carrier assembly 40. Specifically, the rotating mechanism 15 is a rotation fine-tuning platform.

[0032] In some embodiments of the present invention, the winding mechanism 13 includes: a winding bracket 131, an extension arm 132, a winding drive motor (not shown in the figure), a feed reel 134, a take-up reel 135, and at least one traction wheel.

[0033] The take-up bracket 131 is rotatably connected to the output end of the second moving mechanism 12. Specifically, the second slider of the second moving mechanism 12 is connected to the first connecting bracket 14. The first connecting bracket 14 has a first side and a second side arranged opposite each other in the vertical direction. The take-up bracket 131 is rotatably connected to the first side of the first connecting bracket 14 through the rotating mechanism 15. The second side of the first connecting bracket 14 is connected to the second camera mounting bracket 71. The extension arm 132 is connected to the take-up bracket 131. The extension arm 132 extends away from the take-up bracket 131 and extends towards the bottom of the container 50, so that the end of the extension arm 132 facing away from the take-up bracket 131 is closer to the bottom of the container 50 relative to the take-up bracket 131. That is, in the vertical direction, the end of the extension arm 132 facing away from the take-up bracket 131 is located below the take-up bracket 131, so that the end of the extension arm 132 facing away from the take-up bracket 131 can more easily contact the liquid in the container 50.

[0034] A take-up drive motor is connected to the take-up bracket 131 and to the take-up reel 135. The take-up drive motor is also connected to the second traction wheel 1362 and the third traction wheel 1363. One take-up drive motor can simultaneously drive the take-up reel 135 and the second and third traction wheels 1362 and 1363 to rotate, or two take-up drive motors can drive the take-up reel 135 and the second and third traction wheels 1362 and 1363 to rotate respectively. Under the drive of the take-up drive motor, the perforated collection tape 20 is tensioned and runs along the take-up direction. A differential slippage mechanism is designed between the take-up reel 135 and the take-up drive motor.

[0035] A traction wheel is located at one end of the extension arm 132 facing away from the winding support 131. The perforated collection tape 20 is returned from the feed reel 134 to the take-up reel 135 via the traction wheel. When the second moving mechanism 12 drives the winding mechanism 13 to move toward the bottom of the container 50, the perforated collection tape 20 passing through the traction wheel at the end of the extension arm 132 facing away from the winding support 131 first enters the liquid.

[0036] In some embodiments of the present invention, a first traction wheel 1361 is provided on the take-up bracket 131, which is located near the feed reel 134. A pair of second traction wheels 1362 and third traction wheels 1363 are also provided on the take-up bracket 131. A fourth traction wheel 1364 and a fifth traction wheel 1365 are provided on the extension arm 132, with the fifth traction wheel 1365 located at the end of the extension arm 132 facing away from the take-up bracket 131. The take-up bracket 131 is connected to a sixth traction wheel 1366 via a support rod 137, which extends from the take-up bracket 131 away from the extension arm 132. Along the transmission direction of the perforated collection belt 20, the perforated collection belt 20 sequentially passes through the feed reel 134, the first traction wheel 1361, the second traction wheel 1362, the third traction wheel 1363, the fourth traction wheel 1364, the fifth traction wheel 1365, the sixth traction wheel 1366, and the take-up reel 135. When the second moving mechanism 12 drives the winding mechanism 13 to move toward the bottom of the container 50, the extension arm 132 and the fifth traction wheel 1365 of the winding mechanism 13 first come into contact with the liquid in the container 50. The arrangement of the fifth traction wheel 1365 makes it easier for the perforated collection belt 20 to come into contact with the liquid in the container 50.

[0037] In some embodiments of the present invention, the automatic film-collecting machine 100 for perforated collection tape further includes a first camera 60 and a first camera mounting bracket 61. The first camera mounting bracket 61 is connected to the extension arm 132 in a vertical direction. The first camera 60 is connected below the first camera mounting bracket 61, which is above the camera and also serves as a light shield to improve image quality. The perforated collection tape 20 passes through the first camera mounting bracket 61. Along the transmission direction of the perforated collection tape 20, the first camera 60 is located between the supply reel 134 and the end of the extension arm 132 facing away from the take-up bracket 131. The first camera 60 is used to observe the position of the perforated collection tape 20. The position of the perforated collection tape 20 when it passes through the first camera mounting bracket 61 can be observed through the first camera 60, thereby determining whether the movement of the perforated collection tape 20 meets the transmission requirements. When the movement of the perforated collection tape 20 is within a preset range, the supply and take-up operations continue; when the movement of the perforated collection tape 20 is outside the preset range, the position of the perforated collection tape 20 needs to be readjusted. The first camera 60 is also used to obtain the winding length of the perforated collection belt 20 and the number of small holes within the winding length when the perforated collection belt 20 is wound up.

[0038] In some embodiments of the present invention, the automatic film-collecting machine 100 for perforated collection tape further includes a second camera 70 and a second camera holder 71. The second camera holder 71 is connected to the second side of the first connecting bracket 14 and extends toward the container 50. The end of the second camera holder 71 away from the first connecting bracket 14 is connected to the second camera 70. Vertically, the second camera 70 is located above the container 50 and faces the container 50. This allows for observation and monitoring of the film drift and adhesion between the perforated collection tape 20 and the support film through manual and / or automated procedures to determine whether the support film segment is qualified and effective. If effective, the support film segment is collected; if ineffective, the support film segment is skipped, and the process moves to the next support film segment.

[0039] In some embodiments of the present invention, the second driving mechanism 30 includes a third moving mechanism 31, with the film carrier assembly 40 connected to the output end of the third moving mechanism 31. The third moving mechanism 31 drives the film carrier assembly 40 to move vertically, so that at least a portion of the glass slide 42 and at least a portion of the support membrane enter the liquid. Specifically, the third moving mechanism 31 includes a third driving motor 311, a third lead screw 312, a third slider 313, and a third slide rail 314. The third driving motor 311 is driven and connected to the third lead screw 312. The third slider 313 is sleeved on the third lead screw 312 and engages with the third lead screw 312. The third slider 313 cooperates with the third slide rail 314. The third slider 313 is directly or indirectly connected to the film carrier assembly 40. The extension direction of the third lead screw 312 and the extension direction of the third slide rail 314 are the same as the vertical direction. The third drive motor 311 drives the third lead screw 312 to rotate. The third lead screw 312 drives the third slider 313 to move along the extension direction of the third slide rail 314. The third slider 313 drives the film carrier assembly 40 to move in the vertical direction, thereby driving the support film to move in the vertical direction.

[0040] The third moving mechanism 31 and the film carrier assembly 40 are connected by a set of two-dimensional horizontal fine-tuning platforms 90. The horizontal fine-tuning platforms 90 are used to adjust the relative position and distance between the film carrier assembly 40 and the extension arm 132 of the winding mechanism 13, so as to support the overall detachment of the film during the film retrieval process and completely cover the perforated collection belt 20.

[0041] like Figure 4 , Figure 5As shown, in some embodiments of the present invention, the film carrier assembly 40 includes: a film carrier plate 41 and at least two glass slides 42. Specifically, the film carrier plate 41 has a first side and a second side arranged opposite to each other. The second side of the film carrier plate 41 faces the first moving mechanism 11. The first side of the film carrier plate 41 is connected to the output end of the third moving mechanism 31. The third slider 313 of the third moving mechanism 31 is the output end of the third moving mechanism 31. The third slider 313 is connected to the second connecting bracket 32. The side of the second connecting bracket facing the container 50 is provided with a horizontal fine-tuning platform 90. The side of the horizontal fine-tuning platform 90 facing the container 50 is connected to the film carrier fixing frame 33. The film carrier fixing frame 33 is connected to the film carrier assembly 40. The horizontal fine-tuning platform 90 can adjust the slight displacement of the film carrier fixing frame 33 in the X and Y directions of the horizontal plane. The second side of the carrier plate 41 has at least two grooves 411, and each glass slide 42 is disposed in the corresponding groove 411 and fixed by a spring clip at one end of the carrier plate 41. The at least two grooves 411 are arranged sequentially along the second direction to facilitate the sequential immersion of the support film on each glass slide 42 into the liquid. The shape, size, and position of the support film on each glass slide 42 are identical. The second direction is perpendicular to the vertical direction; it can be the same as the first direction or at an angle to the first direction.

[0042] In some embodiments of the present invention, at least two grooves 411 are arranged in a stepped manner along the second direction to facilitate the sequential entry of different support films into the liquid along the second direction, avoiding overlap, intersection, or detachment of adjacent support films on the liquid surface, reducing the complexity of retrieval, and improving the reliability and efficiency of support film retrieval. Specifically, a first groove, a second groove, a third groove, a fourth groove, a fifth groove, and a sixth groove are sequentially provided along the second direction, and the height of the first groove, the second groove, the third groove, the fourth groove, the fifth groove, and the sixth groove increases sequentially along the vertical direction. Each groove 411 corresponds to the installation of a glass slide 42 carrying a support film, that is, along the vertical direction from high to low, the first groove, the second groove, the third groove, the fourth groove, the fifth groove, and the sixth groove respectively correspond to the installation of the first glass slide 42, the second glass slide 42, the third glass slide 42, the fourth glass slide 42, the fifth glass slide 42, and the sixth glass slide 42. When the perforated collection belt 20 corresponds to the first film-retrieval position and descends below the liquid surface, the third moving mechanism 31 controls the film carrier assembly 40 to move downwards a certain depth, so that most of the first support film on the first slide 42 floats on the liquid surface and contacts the first film-retrieval starting position of the perforated collection belt 20. After the first support film is retrieved by the perforated collection belt 20, the perforated collection belt 20 moves to the second film-retrieval position and descends below the liquid surface. The third moving mechanism 31 controls the film carrier assembly 40 to move downwards again a certain depth, so that most of the second support film on the second slide 42 floats on the liquid surface and contacts the second film-retrieval starting position of the perforated collection belt 20. The perforated collection belt 20 is moved to each film-retrieval position in sequence, and the film carrier assembly 40 is moved downwards to the corresponding depth in sequence, until each support film on each slide 42 is retrieved. Each retrieved support film segment is connected end to end, and the connection point is located between the two perforations of the perforated collection belt 20. The height difference between two adjacent grooves 411 is 5mm, and the glass slides 42 are the same size, that is, the height difference between two adjacent glass slides 42 installed on the film plate 41 is 5mm.

[0043] In some embodiments of the present invention, the film carrier assembly 40 further includes a fixing clip 43, which is disposed on the top of the film carrier plate 41. When the glass slide 42 is fixed in the groove 411, the fixing clip 43 contacts the side of the glass slide 42 away from the groove 411 and fixes the glass slide 42 in the groove 411.

[0044] It should be noted that after the support film on each slide 42 is retrieved, there is no need to drive the film carrier assembly 40 to rise; simply keeping the film carrier assembly 40 in its original position is sufficient. When it is necessary to retrieve the support film on the next adjacent slide 42, only a small downward displacement of the film carrier assembly 40 is required. This can greatly shorten the film drifting time and improve the film retrieval efficiency.

[0045] The front view of the perforated collection belt 20 in this embodiment of the invention is as follows: Figure 6 As shown, the perforated collection belt 20 has multiple holes 21 evenly distributed at intervals. The width of the perforated collection belt 20 is 7-9 mm, preferably 8 mm, and the center distance between two adjacent holes 21 is 4-6 mm, preferably 5 mm. The shape of the hole 21 can be a combination of a semi-circle and a rectangle. Specifically, the hole 21 includes three straight sides and one curved side. The three straight sides form an open rectangle, and the curved side seals the opening of the rectangle, forming the hole 21. The length of the hole 21 along the perforated collection belt 20 is 2 mm, and the length along the width direction of the perforated collection belt 20 is 1.5 mm. The specifications and dimensions of the perforated collection belt 20 can be adjusted according to application requirements.

[0046] like Figure 7 As shown, a second aspect of the present invention provides an automatic film retrieval method for perforated collection belts, comprising: Control the perforated collection belt 20 to move to the first film-collecting position so that part of the perforated collection belt 20 is below the liquid surface; Control the membrane carrier assembly 40 to move toward the liquid in the container 50 until most of one end of the first support membrane floats on the liquid surface; The perforated collection belt 20 is controlled to move vertically upward until it is above the liquid surface, and the first support membrane covers the predetermined position of the perforated collection belt 20. The perforated collection belt 20 is wound up to a first support film of a preset length, the preset length of which is an integer multiple of the hole spacing of the perforated collection belt 20. The perforated collection belt 20 is moved to the second film retrieval position, and the above steps are repeated until all support films on the carrier film assembly 40 are retrieved. It is worth noting that the joint position of the two support film sections is between the two small holes of the perforated collection belt 20. This can be achieved by adjusting the position of the first camera and the track position of the monitored collection belt.

[0047] According to an embodiment of the present invention, the automatic film retrieval method using a perforated collection belt firstly moves the perforated collection belt 20 to a first film retrieval position, and then moves a portion of the perforated collection belt 20 below the liquid surface in the container 50 to correspond to the position of the first support film. Next, the film carrier assembly 40 is moved towards the liquid in the container 50, causing one end of the first support film corresponding to the first film retrieval position to float on the liquid surface. Then, the film carrier assembly 40 continues to move towards the bottom of the container 50 until the end of the first support film floating on the liquid surface contacts the perforated collection belt 20. The perforated collection belt 20 is then moved away from the bottom of the container 50 until it is above the liquid surface, at which point the first support film completely covers the perforated collection belt 20. The perforated collection belt 20 is then wound up to a certain length, which is the length of the first support film, at which point all retrieval processes for the first support film are completed. The perforated collection belt 20 is then moved to a second film retrieval position, and the above steps are continued until all support films on the film carrier assembly 40 have been retrieved. The automatic film-collecting machine 100 of the punched collection belt of the present invention can realize automated film collection through the first drive mechanism 10 and the second drive mechanism 30, thereby improving film collection efficiency, ensuring film collection quality, and saving manpower.

[0048] The preparation steps before the automatic film retrieval system of the perforated collection belt are as follows: (1) Film Formation: A glass slide 42 with a certain length and width is inserted into the film solution and pulled out at a uniform speed to form a thin film of a certain thickness and uniformity on the surface of the glass slide. A rectangular support film of a certain width and length is cut on the surface of the glass slide 42 with a blade. The width of the rectangular support film is equal to or slightly smaller than the width of the perforated collection band 20. The preset length of the rectangular support film is an integer multiple of the distance between two adjacent holes in the perforated collection band 20.

[0049] (2) Mounting: At least two glass slides 42 carrying support films are mounted sequentially on the film plate 41 along the length of the film plate 41, and at least two glass slides 42 are arranged in a gradient along the vertical direction.

[0050] The detailed steps of the automatic film retrieval method using a perforated collection belt are as follows: (1) Control the first moving mechanism 11 to drive the winding mechanism 13 to move the perforated collection belt 20 toward the first film retrieval position, and control the first camera 60 to observe and determine the movement of the perforated collection belt. After the first perforated collection belt 20 is positioned, the first moving mechanism 11 drives the perforated collection belt 20 to move to the first film retrieval position, and the second moving mechanism 12 drives one end of the extension arm 132 of the winding mechanism 13 to penetrate a certain depth below the liquid surface. The end of the extension arm 132 away from the winding bracket 131 corresponds to the position of the first support film on the first glass slide 42. (2) The third moving mechanism 31 drives the carrier film assembly 40 to move, so that the carrier film assembly 40 slowly descends to a certain depth (e.g., 5mm) below the liquid surface. The first support film on the first glass slide 42 floats on the liquid surface. The third moving mechanism 31 continues to drive the carrier film assembly 40 to descend until only a small portion of the first support film is attached to the first glass slide 42, and then stops descending. At this time, the end of the first support film away from the first glass slide 42 is about to contact the perforated collection tape 20, and this end is exactly in the middle of the two holes of the perforated collection tape 20. The second camera 70 captures images, and the images captured by the second camera 70 are used to determine whether the first support film is intact. (3) Based on the fact that the first support film is intact on the liquid surface, control the second moving mechanism 12 to drive the winding mechanism 13 to move upward gradually. The first support film gradually covers the perforated collection belt 20 at the corresponding position of the extension arm 132 from the liquid surface until the extension arm 132 is completely exposed on the liquid surface. The first support film completely covers the perforated collection belt 20 and covers the eight complete holes of the perforated collection belt 20. If the area of ​​the first support film floating on the liquid surface is less than the preset floating film area, or if the software judges whether the floating film is intact based on the image captured by the second camera 70 and the actual situation is inconsistent, step (5) is executed directly. (4) Control the winding mechanism 13 to wind up the perforated collection belt 20, and monitor it through the first camera 60 to control the winding of the perforated collection belt 20 to a preset length, which is the length of eight holes. (5) Control the first moving mechanism 11 to drive the winding mechanism 13 to move toward the second film-grabbing position, control the second moving mechanism 12 to drive the winding mechanism 13 to move downward, and the second moving mechanism 12 drives one end of the extension arm 132 of the winding mechanism 13 to penetrate into a certain depth below the liquid surface. The end of the extension arm 132 away from the winding bracket 131 corresponds to the position of the second support film on the second glass slide 42. (6) Control the third moving mechanism 31 to move downward a certain distance (e.g., 5mm) so that the support film on the second glass slide floats on the liquid surface. The third moving mechanism 31 continues to drive the carrier film assembly 40 to descend until only a small portion of the second support film is attached to the first glass slide 42, and then stops descending. At this time, the end of the second support film away from the second glass slide 42 is about to contact the perforated collection tape 20, and this end is exactly in the middle of the two holes of the perforated collection tape 20. The second camera 70 captures images, and the images captured by the second camera 70 are used to determine whether the floating film of the second support film is intact. (7) Repeat steps (3) to (6) until each support film on each glass slide 42 of the film carrier assembly 40 is retrieved; (8) Control the first moving mechanism 11 and the second moving mechanism 12 to move the winding mechanism 13 to the first film retrieval position of the film carrier assembly 40, replace the film carrier assembly 40, and then retrieve the support film on the next set of film carrier assemblies 40.

[0051] It should be noted that the depth at which the extension arm is positioned below the liquid surface away from the winding support, and the depth at which the support membrane of the carrier membrane assembly extends below the liquid surface, can be adjusted according to the actual situation, as long as the end of the support membrane on the carrier membrane assembly that needs to be retrieved floating on the liquid surface can contact the perforated winding tape on the extension arm.

[0052] In this embodiment of the invention, the automatic film-retrieving machine for perforated collection tape can be controlled manually or by a program. When the automatic film-retrieving machine for perforated collection tape is controlled by a program, it may further include a control processor (not shown in the figure), which is electrically connected to the first drive mechanism 10, the second drive mechanism 30, the first camera 60, and the second camera 70, respectively. Specifically, the control processor is electrically connected to the first drive motor 111 of the first moving mechanism 11, the second drive motor 121 of the second moving mechanism 12, the winding drive motor of the winding mechanism 13, and the third drive motor 311 of the third moving mechanism 31, respectively.

[0053] The control processor controls the first drive motor 111 to operate, causing the first moving mechanism 11 to drive the perforated collection belt 20 to move horizontally; the control processor controls the second drive motor 121 to operate, causing the second moving mechanism 12 to drive the perforated collection belt 20 to move vertically; the control processor controls the winding motor to operate, causing the winding mechanism 13 to wind up the perforated collection belt 20; the control processor controls the third drive motor 311 to operate, causing the third drive mechanism 32 to drive the carrier film assembly 40 to move vertically. The control processor can also control the second drive mechanism 20 to drive the carrier film assembly 40 and its load support film to move perpendicular to the vertical direction.

[0054] The control process of the processor is as follows: (1) The control processor controls the first moving mechanism 11 and the second moving mechanism 12 to drive the perforated collection belt 20 to the position of the first support film; at the same time, the control processor controls the first camera 60 to acquire images and determine the first hole position of the perforated collection belt 20 based on the acquired images; (2) The control processor controls the third moving mechanism 31 to drive the carrier film assembly 40 to move below the liquid surface, so that the end of the first support film away from the first glass slide 42 is just about to contact the perforated collection tape 20, and this end is in the middle of the two holes. At the same time, the system judges whether the first support film is intact based on the image captured by the second camera 70; The control processor determines whether the preset floating film quality is met based on the image captured by the second camera 70 and preset parameters such as the area, shape, and position of the floating film portion of the first support membrane on the liquid surface. If the preset floating film quality is met, step (3) is executed directly; or the control processor determines whether the floating film is intact and does not conform to the preset standard based on the image captured by the second camera 70, and executes step (5) directly. (3) The control processor controls the second moving mechanism 12 to drive the winding mechanism 13 to move upward based on the fact that the first support film is intact on the liquid surface, so that the first support film covers the perforated collection belt 20 and covers the eight complete holes. (4) The control processor controls the winding mechanism 13 to wind up the perforated collection tape 20 of a preset length according to the monitoring screen of the first camera 60; (5) The control processor controls the first moving mechanism 11 to drive the perforated collection belt 20 to the position corresponding to the second support membrane; (6) The control processor controls the third moving mechanism 31 to move downwards until the end of the second support film away from the second glass slide 42 is just about to contact the perforated collection tape 20, and the middle position of the two holes at that end; The control processor determines whether the second support membrane is intact based on the image captured by the second camera 70. (7) Control the processor to repeatedly execute steps (3) to (6) until each support film on each glass slide 42 of the film carrier assembly 40 is retrieved; (8) The control processor controls the first moving mechanism 11 and the second moving mechanism 12 to move the winding mechanism 13 to the first film retrieval position of the film carrier assembly 40, and after replacing the film carrier assembly 40, the next set of support films is retrieved.
