DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0036] It should also be understood that the terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and the appended claims of the present application, the singular forms “a”, “an” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0037] It should be further understood that the term “and / or” used in the specification and the appended claims of the present application means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0038] In the prior art, slide pushing machines, dyeing machines, slide reading machines, slide storage and transfer mechanisms and other devices all involve the clamping and transportation of slides. Generally, slides are fed by slide baskets. When the volume of the slide basket is small, the spacing between adjacent slides is small, and it is not easy to clamp the target slide, and non-target slides are easily touched.

[0039] To solve the above problems, the application provides a slide transfer device and a slide clamping method.

[0040] Some embodiments of the application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the features described in the following examples and embodiments can be combined with each other.

[0041] Please refer to Figure 1 and Figure 2 The embodiments of the application provide a slide transfer device 100, which comprises a feeding device 20, a clamping device 10 and a controller 60.

[0042] The feeding device 20 is used to feed the slide basket 70 loaded with the to-be-tested slides to the slide clamping position. The clamping device 10 is used to clamp and move the target slide 80 from the slide basket 70.

[0043] The controller 60 is used to control the clamping device 10 to clamp the target slide 80 from the slide basket 70 and move the target slide 80 out of a first distance after the feeding device 20 feeds the slide basket 70. After the target slide 80 moves the first distance, the controller 60 controls the clamping device 10 to release the clamping of the target slide 80, and controls the clamping device 10 to clamp the target slide 80 from the slide basket 70 and move the target slide 80 out of the slide basket 70.

[0044] Exemplarily, the slide transfer device 100 can be a slide reading instrument, a slide pushing machine, a dyeing machine and other devices related to the transfer and transportation of slides. In the embodiments of the application, the slide reading instrument is taken as an example for description.

[0045] The controller 60 controls the clamping device 10 to clamp the target slide 80 from the slide basket 70 for the first time and move the target slide 80 out of the slide basket 70 by a first distance in a direction away from the slide basket 70 to separate the target slide 80 from the non-target slides, and the target slide 80 is still partially accommodated in the slide basket 70 at this time. After the target slide 80 is moved by the first distance, the controller 60 controls the clamping device 10 to release the clamping of the target slide 80, and controls the clamping device 10 to move in a direction opposite to the direction of the movement by the first distance and clamp the target slide 80 from the slide basket 70 for the second time, and then move the target slide 80 out of the slide basket 70 completely to complete the clamping of the target slide 80. In some embodiments, the slide transfer device 100 further comprises a microscope device 30, and after the clamping device 10 clamps the target slide 80 from the slide basket 70 and moves the target slide 80 out of the slide basket 70, the target slide 80 is transported to a preset microscope position of the microscope device 30, so that the microscope device 30 performs a microscope operation on the target slide 80 clamped by the clamping device 10.

[0046] By clamping the target slide 80 from the slide basket 70 by the first distance, the target slide 80 is at least extended by the first distance out of the slide basket 70, and the target slide 80 is separated from the non-target slides. At this time, the clamping of the target slide 80 is released and then clamped again, which is not interfered by the non-target slides, and the target slide 80 can be clamped with more contact area, so that the target slide 80 is clamped and transported more stably subsequently. Further, in the case that the volume of the slide basket 70 is reduced and the distance between the slides is reduced, the interference of the non-target slides during the clamping of the target slide 80 can be avoided, and the target slide 80 can be clamped accurately.

[0047] Please refer to Figure 3 and Figure 4 In some embodiments, the clamping device 10 comprises a first clamping assembly 11 and a second clamping assembly 12 cooperating with the first clamping assembly 11 to clamp the target slide 80, the first clamping assembly 11 comprises a first clamping arm 111 and a first clamping piece 112 connected with the first clamping arm 111 and at least partially exposed outside the first clamping arm 111, and the second clamping assembly 12 comprises a second clamping arm 121 movably connected with the first clamping arm 111 and a second clamping piece 122 connected with the second clamping arm 121 and at least partially exposed outside the second clamping arm 121. The target slide 80 is clamped and moved out by the first distance by the cooperation of the first clamping piece 112 and the second clamping piece 122, and the target slide 80 is clamped and moved out of the slide basket 70 by the cooperation of the first clamping arm 111 and the second clamping arm 121.

[0048] For example, the first clamping member 112 and the second clamping member 122 can be elastic clips. In the direction of displacement of the first distance, the first clamping member 112 and the second clamping member 122 are exposed outside the first clamping arm 111 and the second clamping arm 121, respectively. When the controller 60 controls the clamping device 10 to clamp the target glass slide 80 for the first time, the first clamping member 112 and the second clamping member 122 cooperate to clamp the target glass slide 80. The first clamping arm 111 and the second clamping arm 121 cooperate to clamp the target glass slide 80 for the second time after displacement of the first distance and remove the target glass slide 80 from the slide basket 70.

[0049] See also Figure 5 In some embodiments, the thickness of the first clamping member 112 and the second clamping member 122 in the first direction are both smaller than the thickness of the first clamping arm 111 and the second clamping arm 121 in the first direction, and the first direction is the direction in which the second clamping member 122 and the first clamping member 112 move away from or closer to each other and undergo relative displacement.

[0050] By setting the thickness of the first clamping member 112 and the second clamping member 122 in the first direction to be smaller than the thickness of the first clamping arm 111 and the second clamping arm 121 in the first direction, when the distance between the target glass slide 80 and the non-target glass slide is small, the target glass slide 80 can be clamped for the first time by the first clamping member 112 with a smaller thickness and exposed to the first clamping arm 111, and the second clamping member 122 with a smaller thickness and exposed to the second clamping arm 121, so that the target glass slide 80 is moved out of the glass slide basket 70 by the first distance, so that the target glass slide 80 protrudes from the glass slide basket 70 by at least the first distance. At this time, when the target glass slide 80 is clamped again, there will be no interference from the non-target glass slide, and the glass slide can be clamped with a larger contact area during the second clamping, so that the target glass slide 80 can be clamped and transported more securely in the subsequent transportation.

[0051] See also Figure 5 In some embodiments, when the first clamping assembly 11 and the second clamping assembly 12 release the clamping of the target glass slide 80, the distance between the first clamping arm 111 and the second clamping arm 121 in the first direction is less than or equal to the distance between the first clamping member 112 and the second clamping member 122 in the first direction.

[0052] Exemplarily, when the first clamping assembly 11 and the second clamping assembly 12 release the clamping on the target slide 80, in the non-clamping state, the distance between the first clamping arm 111 and the second clamping arm 121 in the first direction is less than or equal to the distance between the first clamping part 112 and the second clamping part 122 in the first direction. That is, the distance between the side of the first clamping arm 111 facing the second clamping arm 121 and the side of the second clamping arm 121 facing the first clamping arm 111 in the first direction is less than or equal to the distance between the side of the first clamping part 112 facing the second clamping part 122 and the side of the second clamping part 122 facing the first clamping part 112 in the first direction. Thus, when the target slide 80 is clamped again, the first clamping arm 111 and the second clamping arm 121 contact the target slide 80 and clamp the target slide 80, achieving stable clamping of the target slide 80.

[0053] In some embodiments, the thickness of the first clamping arm 111 and the second clamping arm 121 in the first direction is 0.8mm-1.3mm.

[0054] Please refer to Figure 4 In some embodiments, the first clamping part 112 includes a first clamping portion 1121 exposed to the first clamping arm 111 and a first connecting portion 1122 connected to the first clamping arm 111, and the second clamping part 122 includes a second clamping portion 1221 exposed to the second clamping arm 121 and a second connecting portion 1222 connected to the second clamping arm 121.

[0055] The width of the first clamping portion 1121 in the second direction is greater than the width of the first connecting portion 1122 in the second direction, and the width of the second clamping portion 1221 in the second direction is greater than the width of the second connecting portion 1222 in the second direction, wherein the second direction, the first direction, and the displacement direction of the target slide 80 moving the first distance are perpendicular to each other.

[0056] Exemplarily, the first clamping part 112 includes a first clamping portion 1121 exposed to the first clamping arm 111 and a first connecting portion 1122 connected to the first clamping arm 111, and the second clamping part 122 includes a second clamping portion 1221 exposed to the second clamping arm 121 and a second connecting portion 1222 connected to the second clamping arm 121. When the controller 60 controls the clamping device 10 to clamp the target slide 80 for the first time, the first clamping portion 1121 and the second clamping portion 1221 cooperate to clamp the target slide 80.

[0057] By setting the first clamping part 1121 exposed to the first clamping arm 111 and the first connecting part 1122 connected to the first clamping arm 111, the second clamping part 1221 exposed to the second clamping arm 121 and the second connecting part 1222 connected to the second clamping arm 121, and setting the width of the clamping part in the second direction greater than that of the connecting part, the contact area of the clamping part in clamping the target slide 80 is increased, so that the clamping is more stable and firm.

[0058] In some embodiments, the clamping device 10 is further provided with an adjusting mechanism (not shown in the figure), which is connected with the first clamping part 112 and the second clamping part 122, and is used to drive the first clamping part 112 and the second clamping part 122 to displace in the displacement direction of the first distance, so as to adjust the exposed area of the first clamping part 1121 and the second clamping part 1221 exposed to the first clamping arm 111 and the second clamping arm 121.

[0059] For example, when the clamping device 10 does not need to clamp the target slide 80 by the first clamping part 1121 and the second clamping part 1221 for the first time, the adjusting mechanism retracts the exposed first clamping part 1121 and the second clamping part 1221 completely, and they are no longer exposed to the first clamping arm 111 and the second clamping arm 121; or, according to the actual use requirement, the adjusting mechanism makes the first clamping part 112 and the second clamping part 122 extend outward to increase the exposed area of the first clamping part 1121 and the second clamping part 1221.

[0060] In some embodiments, the clamping device 10 further comprises a resilient pressing part 13 and a clamping tooth part 14 for clamping the target slide 80 in cooperation with the resilient pressing part 13. Either the resilient pressing part 13 or the clamping tooth part 14 is arranged on the side of the first clamping arm 111 facing the second clamping arm 121, and the other is arranged on the side of the second clamping arm 121 facing the first clamping arm 111. The controller 60 is used to control the clamping device 10 to clamp the target slide 80 from the slide basket 70 by the resilient pressing part 13 and the clamping tooth part 14 and move the target slide 80 out of the slide basket 70 after the target slide 80 moves the first distance.

[0061] For example, the clamping tooth part 14 can be spaced apart and protrude from the second clamping arm 121 towards the first clamping arm 111. The resilient pressing part 13 is arranged on the side of the first clamping arm 111 facing the second clamping arm 121, and the clamping tooth part 14 is arranged on the side of the second clamping arm 121 facing the first clamping arm 111; or, the clamping tooth part 14 is arranged on the side of the first clamping arm 111 facing the second clamping arm 121, and the resilient pressing part 13 is arranged on the side of the second clamping arm 121 facing the first clamping arm 111.

[0062] The elastic pressing member 13 and the clamping tooth portion 14 are arranged to clamp the target slide 80 from the slide basket 70 in the second clamping process of the clamping mechanism. The elastic pressing member 13 is in contact with the target slide 80 and is gradually compressed under the action of the elastic pressing member 13 to moderate the clamping force, thereby avoiding the breakage of the target slide 80 in the process of applying the clamping force. Meanwhile, the clamping tooth portion 14 arranged in cooperation with the elastic pressing member 13 increases the clamping stability and flatness of the clamping mechanism to the slide.

[0063] In some embodiments, the elastic pressing member 13 is arranged as at least two and is arranged at intervals on the side of the first clamping arm 111 facing the second clamping arm 121 or on the side of the second clamping arm 121 facing the first clamping arm 111.

[0064] The arrangement of at least two elastic pressing members 13 can better and uniformly moderate the clamping force and better avoid the breakage of the target slide 80 in the process of applying the clamping force.

[0065] Please refer to Figure 4 and Figure 5 In some embodiments, the first clamping member 112 is connected to the side of the first clamping arm 111 facing the clamping opening, and the second clamping member 122 is connected to the side of the second clamping arm 121 facing the clamping opening; the side of the first clamping member 112 facing the clamping opening or the side of the second clamping member 122 facing the clamping opening is flush with the side of the elastic pressing member 13 facing the clamping opening.

[0066] For example, the elastic pressing member 13 is provided with two elastic pressing members 13. When the elastic pressing member 13 is arranged on the side of the first clamping arm 111 facing the second clamping arm 121, the two elastic pressing members 13 are arranged at intervals on the opposite sides of the first clamping member 112; when the elastic pressing member 13 is arranged on the side of the second clamping arm 121 facing the first clamping arm 111, the two elastic pressing members 13 are arranged at intervals on the opposite sides of the second clamping member 122.

[0067] The arrangement of the side of the first clamping member 112 facing the clamping opening or the side of the second clamping member 122 facing the clamping opening flush with the side of the elastic pressing member 13 facing the clamping opening increases the clamping contact area of the clamping device 10 when clamping the target slide 80, thereby improving the clamping stability and flatness of the clamping device 10 to the target slide 80 and facilitating the subsequent microscopic examination of the target slide 80 clamped on the clamping device 10 by the microscopic examination device 30.

[0068] In some embodiments, the first clamping member 112 is connected to the side of the first clamping arm 111 facing the clamping opening, and the second clamping member 122 is connected to the side of the second clamping arm 121 facing the clamping opening; the side of the first clamping member 112 or the side of the second clamping member 122 facing the clamping opening is flush with the side of the clamping tooth portion 14 facing the clamping opening.

[0069] Exemplarily, a plurality of clamping tooth portions 14 are spaced apart and protrude from the second clamping arm 121 towards the first clamping arm 111. By providing the clamping tooth portion 14 cooperating with the elastic pressing member 13, the clamping stability and flatness of the slide by the clamping device 10 are improved.

[0070] When the clamping tooth portion 14 is provided on the side of the first clamping arm 111 facing the second clamping arm 121, at least two clamping tooth portions 14 are provided on one end of the first clamping arm 111, and at least two clamping tooth portions 14 are provided on the other end of the first clamping arm 111. The first clamping member 112 is provided between the two groups of clamping tooth portions 14 provided on the opposite ends. When the clamping tooth portion 14 is provided on the side of the second clamping arm 121 facing the first clamping arm 111, at least two clamping tooth portions 14 form a clamping tooth assembly provided on one end of the first clamping arm 111, and at least two clamping tooth portions 14 form another clamping tooth assembly provided on the other end of the first clamping arm 111. The second clamping member 122 is provided between the two clamping tooth assemblies provided on the opposite ends.

[0071] By making the side of the first clamping member 112 or the side of the second clamping member 122 facing the clamping opening flush with the side of the clamping tooth portion 14 facing the clamping opening, the clamping contact area when the target object is clamped by the clamping device 10 is improved, so as to improve the clamping stability and flatness of the target slide 80 by the clamping device 10, and facilitate the microscopic examination of the target slide 80 clamped on the clamping device 10 by the microscope device 30.

[0072] Please refer to Figure 3 In some embodiments, the clamping device 10 further comprises an elastic assembly 15 and a driving assembly 16.

[0073] The elastic assembly 15 is connected to at least one of the first clamping assembly 11 and the second clamping assembly 12, so as to form an elastic clamping cooperation between the first clamping assembly 11 and the second clamping assembly 12. The driving assembly 16 is connected to the controller 60 and is used to drive the second clamping assembly 12 to move relative to the first clamping assembly 11 to the side away from the first clamping assembly 11 to form the clamping opening against the elastic resistance of the elastic assembly 15.

[0074] When the driving assembly 16 stops driving the second clamping assembly 12, the second clamping assembly 12 moves to the side close to the first clamping assembly 11 under the action of the elastic assembly 15 to close the clamping opening and clamp the target slide 80.

[0075] The controller 60 is further configured to, when receiving the clamping instruction, control the driving assembly 16 to drive the second clamping assembly 12 to displace relative to the first clamping assembly 11 against the elastic resistance of the elastic assembly 15 to form a clamping opening; when receiving that there is a glass sheet in the clamping opening, control the driving assembly 16 to stop driving the second clamping assembly 12, so that the second clamping assembly 12 displaces relative to the first clamping assembly 11 under the action of the elastic assembly 15 to close the clamping opening and clamp the target glass sheet 80 in the clamping opening.

[0076] For example, before clamping the target glass sheet 80, the first clamping assembly 11 and the second clamping assembly 12 are kept in the closed clamping state under the action of the elastic assembly 15. When receiving the clamping instruction, the second clamping assembly 12 is driven by the driving assembly 16 to displace relative to the first clamping assembly 11 against the elastic resistance of the elastic assembly 15 to form a clamping opening. When the driving assembly 16 stops driving the second clamping assembly 12, the second clamping assembly 12 displaces relative to the first clamping assembly 11 under the action of the elastic assembly 15 to close the clamping opening and clamp the target glass sheet 80 in the clamping opening.

[0077] For example, the first clamping assembly 11 and the second clamping assembly 12 are kept in the closed clamping state under the action of the elastic assembly 15. When receiving the clamping instruction, the second clamping assembly 12 is driven by the driving assembly 16 to displace relative to the first clamping assembly 11 against the elastic resistance of the elastic assembly 15 to form a clamping opening. When the driving assembly 16 stops driving the second clamping assembly 12, the second clamping assembly 12 displaces relative to the first clamping assembly 11 under the action of the elastic assembly 15 to close the clamping opening and clamp the target glass sheet 80 in the clamping opening. Figure 6 In some embodiments, the clamping device 10 further comprises a movable platform 18, and the first clamping assembly 11 and the second clamping assembly 12 are arranged on the movable platform 18 and used to drive the first clamping assembly 11 and the second clamping assembly 12 to displace.

[0078] After the sample feeding device 20 feeds the glass sheet basket 70, the controller 60 controls the clamping device 10 to clamp the target glass sheet 80 from the glass sheet basket 70 and move the target glass sheet 80 by the movable platform 18 by a first distance. After the target glass sheet 80 is moved by the first distance, the clamping device 10 is controlled to release the clamping of the target glass sheet 80, and the clamping device 10 is controlled to clamp the target glass sheet 80 from the glass sheet basket 70 and move the target glass sheet 80 by the movable platform 18 out of the glass sheet basket 70.

[0079] For example, the movable platform 18 comprises a first driving component 181 and a second driving component 182 connected with the controller 60. The first driving component 181 is used to drive the clamping device 10 to displace in the direction of the first distance. The second driving component 182 is used to drive the clamping device 10 to displace in the direction perpendicular to the direction of the first distance, so as to displace the target glass sheet 80 to the preset microscopic position of the microscope device 30, and the microscope device 30 performs the microscopic operation on the target glass sheet 80 clamped by the clamping device 10.

[0080] In some embodiments, the controller 60 is further configured to control the first and second clamping arms 111 and 121 to clamp the target slide 80 and move the target slide 80 partially into the slide basket 70. After the target slide 80 is partially moved into the slide basket 70, the controller 60 controls the first and second clamping arms 111 and 121 to release the clamping of the target slide 80 and controls the first and second clamping members 112 and 122 to clamp the target slide 80 and move the target slide 80 completely into the slide basket 70.

[0081] For example, after the microscope 30 completes the microscopic operation on the target slide 80, the controller 60 controls the clamping device 10 to clamp the target slide 80 and move the target slide 80 completely out of the slide basket 70 to a position where the target slide 80 is completely moved out of the slide basket 70 when the clamping device 10 clamps the target slide 80. After the clamping device 10 is moved to the position, the controller 60 controls the clamping device 10 to move towards the slide basket 70 in a direction opposite to the direction in which the clamping device 10 is moved by the first distance, so that the target slide 80 is partially placed in the slide basket 70, and the target slide 80 is misaligned with the non-target slides. After the target slide 80 is partially placed in the slide basket 70, the controller 60 controls the first and second clamping arms 111 and 121 to release the clamping of the target slide 80 and controls the clamping device 10 to move in a direction opposite to the direction in which the clamping device 10 is moved by the first distance and clamp the target slide 80 again by the first and second clamping members 112 and 122. After the clamping device 10 clamps the target slide 80 again, the controller 60 controls the clamping device 10 to move towards the slide basket 70 by the first distance, so that the target slide 80 is completely moved into the slide basket 70, and the target slide 80 is returned.

[0082] In some embodiments, after the sample feeding device 20 feeds the slide basket 70, the controller 60 controls the clamping device 10 to horizontally clamp the target slide 80 from the slide basket 70 and move the target slide 80 by the first distance.

[0083] For example, after the sample feeding device 20 feeds the slide basket 70, the controller 60 controls the clamping device 10 to horizontally clamp the target slide 80 from the slide basket 70 and move the target slide 80 by the first distance. By horizontally clamping the target slide 80 by the clamping device 10, the flatness requirement of the subsequent operation is met.

[0084] In some embodiments, the controller 60 is further configured to control the clamping device 10 to horizontally clamp the target slide 80 and move the target slide 80 completely into the slide basket 70.

[0085] Exemplarily, after the target slide 80 clamped by the clamping device 10 completes the microscopic examination operation, the first clamping arm 111 and the second clamping arm 121 horizontally clamp the target slide 80 at this time and are displaced toward the direction opposite to the direction of displacement of the first distance, so as to partially place the target slide 80 in the slide basket 70; after the target slide 80 is partially placed in the slide basket 70, the first clamping arm 111 and the second clamping arm 121 are controlled to release the clamping of the target slide 80, and the clamping device 10 is controlled to be displaced toward the direction opposite to the direction of displacement of the first distance and to horizontally clamp the target slide 80 again through the first clamping member 112 and the second clamping member 122. After the clamping device 10 clamps the target slide 80 again, the controller 60 controls the clamping device 10 to be displaced toward the slide basket 70 by the first distance, so as to completely move the target slide 80 into the slide basket 70.

[0086] In some embodiments, the slide transfer device 100 further comprises a turnover mechanism 40, and the controller 60 is configured to control the turnover mechanism 40 to receive the slide basket 70 loaded with the to-be-tested slides after the sample feeding device feeds the slide basket 70, and to turn over the slide basket 70 so that the to-be-tested slides are in a horizontal state; or, after the controller 60 controls the clamping device 10 to horizontally clamp the target slide 80 and completely move the target slide 80 into the slide basket 70 received by the turnover mechanism 40, the controller 60 controls the turnover mechanism 40 to turn over so that the target slide 80 is in a vertical state.

[0087] Exemplarily, the controller 60 is configured to control the turnover mechanism 40 to receive the slide basket 70 loaded with the to-be-tested slides after the sample feeding device feeds the slide basket 70, and to turn over the slide basket 70 so that the slide basket 70 is turned over from an open vertical state to an open horizontal state, and the to-be-tested slides in the slide basket 70 are in a horizontal state to be clamped. Alternatively, after the controller 60 controls the clamping device 10 to horizontally clamp the target slide 80 and completely move the target slide 80 into the slide basket 70 received by the turnover mechanism 40, if all the to-be-tested slides in the slide basket 70 have completed the microscopic examination operation, the controller 60 controls the turnover mechanism 40 to turn over so that the slide basket 70 is turned over from an open horizontal state to an open vertical state, and the target slide 80 is in a vertical state.

[0088] In some embodiments, the slide transfer device 100 further comprises an emergency device 50, and the emergency device 50 is configured to transport the slide basket 70.

[0089] Exemplarily, during the use of the slide viewer, there is a case that needs to give priority to the microscopic examination operation on the to-be-tested slides in another slide basket 70. The user places the slide basket 70 needing emergency priority treatment in the emergency device 50, and the emergency device 50 receives the slide basket 70 and transports the slide basket 70 to the turnover mechanism 40. After the turnover mechanism 40 receives the slide basket 70, the target slide 80 in the slide basket 70 is clamped by the clamping device 10 and is transported to the microscopic examination device 30 for subsequent microscopic examination operation.

[0090] Referring to Figure 7 , Figure 7 A glass sheet clamping method is provided for the glass sheet transfer device 100 described above, and the method comprises the following steps:

[0091] S10: control the sample feeding device to feed the glass sheet basket loaded with the to-be-tested glass sheets;

[0092] S11: control the clamping device to clamp the target glass sheet from the glass sheet basket and move the target glass sheet out by a first distance;

[0093] S12: after the target glass sheet is moved by the first distance, control the clamping device to release the clamping of the target glass sheet, and control the clamping device to clamp the target glass sheet from the glass sheet basket and move the target glass sheet out of the glass sheet basket.

[0094] The sample feeding device feeds the glass sheet basket loaded with the to-be-tested glass sheets to the glass sheet clamping position, the clamping device clamps the target glass sheet from the glass sheet basket and moves the target glass sheet out by a first distance, the target glass sheet is separated from the non-target glass sheets, the clamping is released, the target glass sheet is clamped again and moved out of the glass sheet basket. The contact between the target glass sheet and the non-target glass sheets during the clamping of the target glass sheet is avoided, and the accurate clamping of the target glass sheet is realized. Further, in the case that the volume of the glass sheet basket is reduced and the distance between the glass sheets is reduced, the accurate clamping of the target glass sheet can be better realized.
