[0063] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0064] Reference is made below to the accompanying drawings Figures 1-16 A sensor position adjustment mechanism 100, a sensor assembly 200, and a cover glass machine 1000 according to embodiments of the present application are described below.

[0065] The sensor position adjustment mechanism 100 according to embodiments of the present application includes a base 110, a sensor mounting plate 120, and a driving device 130. The sensor mounting plate 120 is movably provided to the base 110, for example, the sensor mounting plate 120 is connected to the base 110 and is movable relative to the base 110. In addition, the sensor mounting plate 120 is used to mount a sensor 210, as described below. The driving device 130 is provided to the base 110, connected to the sensor mounting plate 120, and includes a driving member 131 configured to drive the sensor mounting plate 120 to move.

[0066] With the sensor position adjustment mechanism 100 according to an embodiment of the present invention, when the sensor 210 mounted thereon deviates from the desired position, the driving device 130 can drive the sensor mounting plate 120, thereby causing the sensor 210 mounted on the sensor mounting plate 120 to move, thereby adjusting the position of the sensor 210 so that it is aligned with the desired position again. In this way, the sensor 210 can accurately identify the glass slide 1300 that has been transferred to the desired position by the bracket 1200, allowing the gripping device 1400 (e.g., a robotic arm) to grip the glass slide 1300 at the desired position for the next operation, such as sealing the glass slide 1300, i.e., applying a cover glass thereto.

[0067] In order to better understand the present invention, it should be noted that the desired position in the present invention is pre-set and may change. During the initial installation, the sensor position adjustment mechanism 100 and the sensor 210 located thereon need to be preliminarily aligned with the gripping device 1400. For example, the sensor position adjustment mechanism 100 is mounted to the positioning plate 1100, and the positioning plate 1100 has a positioning opening 1110, and the positioning opening 1110 is aligned with the gripping device 1400, and the sensor position adjustment mechanism 100 is located at the positioning opening 1110 and is also aligned with the positioning opening 1110, so that the sensor position adjustment mechanism 100 and the sensor 210 located thereon are aligned with the gripping device 1400.

[0068] In this case, the gripping device 1400, which has already gripped the glass slide 1300, is lowered to the gripping position. The sensor position adjustment mechanism 100 is then operated to adjust the position of the sensor 210 mounted thereon so that the light emitted by the sensor 210 illuminates the side of the glass slide 1300 being gripped by the gripping device 1400. At this point, the glass slide 1300 is at the desired position, and the sensor 1300 is aligned with the desired position. In this way, whenever the sensor 210 detects the glass slide 1300 at the desired position, the support 1200 stops transporting the glass slide 1300. In theory, the gripping device 1400 can always grip the glass slide 1300 at the desired position.

[0069] However, due to possible errors in the movement of the gripping device 1400, the position of the glass slide 1300 in the bracket 1200 may be incorrect, and human errors may occur in the process of initially determining the desired position, when the sensor 210 detects the glass slide 1300, the glass slide 1300 should be at the desired position, but the gripping device 1400 may not be able to grip the glass slide 1300. This indicates that there is an error (or change) in the desired position, for example, there is an error between the current or actual gripping position of the gripping device 1400 and the previous desired position. In this case, the position of the sensor 210 can be adjusted by the sensor position adjustment mechanism 100 to align the sensor 210 with the current gripping position of the gripping device 1400, thereby offsetting the error in the desired position. For example, the desired position is adjusted (or updated) to the current gripping position of the gripping device 1400 to ensure that the gripping device 1400 can grip the glass slide 1300 detected by the sensor 210.

[0070] like Figures 9-11 As shown, the sensor mounting plate 120 includes a first plate portion 121, a second plate portion 122 and a third plate portion 123. The first plate portion 121 is set to the base 110 and connected to the driving device 130, the second plate portion 122 is connected to the first plate portion 121, and the third plate portion 123 is connected to the second plate portion 122. The second plate portion 122 and the third plate portion 123 are in the moving direction of the sensor mounting plate 120 (for example, Figure 4 In some embodiments, the second plate portion 122 may have a first thickness, the third plate portion 123 may have a second thickness, and the first thickness is greater than the second thickness. For example, the difference T between the first thickness and the second thickness is approximately 1.7 mm to 1.9 mm, specifically 1.8 mm. Further, one side of the second plate portion 122 (for example Figure 4 the left side shown) and one side of the third plate portion 123 (eg Figure 4 The left side shown in FIG. 1 may be flush with the second plate portion 122 and the third plate portion 123 in the moving direction of the sensor mounting plate 120 (eg Figure 4 For example, the third plate portion 123 is arranged at a position further to the left than the second plate portion 122. In the embodiment of the present utility model, the first plate portion 121, the second plate portion 122 and the third plate portion 123 can be integrated.

[0071] In some embodiments, as Figures 9-11 As shown, the first plate portion 121 and the second plate portion 122 have the same thickness and are disposed at the same position along the moving direction of the sensor mounting plate 120 .

[0072] In the embodiment of the present utility model, Figure 6 and7 As shown, the sensor 210 includes a first sensor 211 and a second sensor 212. The first sensor 211 is mounted to the second plate portion 122, and the second sensor 212 is mounted to the third plate portion 123. As described above, since the second plate portion 122 and the third plate portion 123 are in the moving direction of the sensor mounting plate 120 (e.g. Figure 4 The first sensor 211 and the second sensor 212 are arranged at different positions in the moving direction of the sensor mounting plate 120 (eg the left and right directions shown in FIG. 1 ). Figure 4 The first sensor 211 and the second sensor 212 are also arranged at different positions in the left and right directions (as shown). Each of the first sensor 211 and the second sensor 212 includes an emitter 213 and a receiver 214 arranged side by side. The emitter 213 is used to emit light (such as infrared light) toward the object to be detected (such as the support 1200 or the slide 1300), and the receiver 214 is used to receive the light reflected by the object to detect the object.

[0073] Further, if Figure 9 and 10 As shown, the second plate portion 122 has a first mounting hole 1221 and a second mounting hole 1222, respectively located at opposite ends of the second plate portion 122. The first mounting hole 1221 can be a circular hole, while the second mounting hole 1222 can be an elliptical hole or a stadium-shaped hole. The first sensor 211 has a circular mounting hole aligned with the first mounting hole 1221 and the second mounting hole 1222. Therefore, two fasteners (such as screws or bolts) can be passed through the aligned mounting holes to mount the first sensor 211 to the second plate portion 122. In addition, the position of the fasteners within the second mounting hole 1222 can be adjusted, thereby adjusting the posture of the first sensor 211.

[0074] Similarly, the third plate portion 123 has a third mounting hole 1231 and a fourth mounting hole 1232, located at opposite ends of the third plate portion 123. The third mounting hole 1231 can be a circular hole, while the fourth mounting hole 1232 can be an elliptical hole or a stadium-shaped hole. The second sensor 212 has a circular mounting hole aligned with the third mounting hole 1231 and the fourth mounting hole 1232. Therefore, two fasteners (such as screws or bolts) can be inserted through the aligned mounting holes to attach the second sensor 212 to the third plate portion 123. Furthermore, the position of the fasteners within the fourth mounting hole 1232 can be adjusted, thereby adjusting the posture of the second sensor 212.

[0075] In some embodiments, the first sensor 211 may be a slide sensor for detecting the slide 1300, and the second sensor 212 may be a rack sensor for detecting the rack 1200. In the slide sensor, the emitter 213 is used to emit light toward the slide 1300, and the receiver 214 is used to receive light reflected from the slide 1300, thereby detecting the slide 1300. In the rack sensor, the emitter 213 is used to emit light toward the rack 1200, and the receiver 214 is used to receive light reflected from the rack 1200, thereby detecting the rack 1200.

[0076] In the embodiment of the present utility model, Figure 4 As shown, the left surface of the sensor mounting plate 120 is flat, and the thickness of the second plate portion 122 is greater than the thickness of the third plate portion 123, with the difference between the two being T. Therefore, the distance between the vertical center plane of the second sensor 212 (e.g., the bracket sensor) and the vertical center plane of the first sensor 211 (e.g., the slide sensor) is T / 2. For example, the vertical center plane of the second sensor 212 is located T / 2 to the left of the vertical center plane of the first sensor 211. It should be noted that the first sensor 211 and the second sensor 212 in this embodiment of the present invention are structurally identical and are only used to detect different objects, such as the bracket 1200 and the slide 1300.

[0077] Furthermore, based on the T / 2 distance between the vertical center plane of the second sensor 212 and the vertical center plane of the first sensor 211, and by setting the thickness of the portion of the ear of the bracket 1200 that can be detected by the slide sensor, the distance between the first and last slides 1300 in the bracket 1200 and the ear of the bracket 1200, and the distance between the two slides 1300, for example, the thickness of the portion of the ear of the bracket 1200 that can be detected by the slide sensor is about 3 mm, the distance between the first slide 1300 in the bracket 1200 and the ear of the bracket 1200 is about 9 mm, and the distance between the two slides 1300 is about 10 mm. The distance between each glass slide 1300 is approximately 2.25 mm, and the distance between the last glass slide 1300 in the rack 1200 and the ear of the rack 1200 is approximately 2.7 mm. Therefore, during the movement of the rack 1200, at a certain moment, the first sensor 211 and the second sensor 212 simultaneously detect the ear of the rack 1200, at which point the entire grasping process for all glass slides 1300 begins. Subsequently, when the first sensor 211 detects the first glass slide 1300 (at this time, the second sensor 212 does not detect the rack 1200), the grasping device 1400 grasps the first glass slide 1300. Accordingly, during the movement of the rack 1200, at another moment, the first sensor 211 and the second sensor 212 simultaneously detect the ear of the rack 212, at which point all glass slides 1300 have been grasped, and the entire grasping process for all glass slides 1300 ends.

[0078] like Figures 6-8 As shown, the base 110 includes opposite side walls 111 and a back plate 112, the back plate 112 is connected between the opposite side walls 111, and the first plate portion 121 is disposed between the opposite side walls 111 of the base 110 and is movable between the opposite side walls 111 of the base 110, for example, along Figure 4 Move left and right as shown.

[0079] Furthermore, the back plate 112 of the base 110 includes adjacent positioning pins 113 and mounting holes 114. The positioning pins 113 are used to align the base 110 with its mounting position, and the mounting holes 114 are used to pass fasteners (such as screws or bolts) to mount the base 110 at the mounting position. Figure 5 As shown, the positioning plate 1100 has a mounting opening 1120 , and the positioning pin 113 can be engaged in the mounting opening 1120 to align the mounting hole 114 with the mounting opening 1120 , so that the fastener can pass through the mounting hole 114 and the mounting opening 1120 , thereby mounting the base 110 to the positioning plate 1100 .

[0080] Specifically, the back plate 112 of the base 110 can have two spaced-apart locating pins 113 and two spaced-apart mounting holes 114, and the two locating pins 113 and the two mounting holes 114 are alternately arranged, for example, one locating hole 114 is arranged between the two locating pins 113, and one locating pin 113 is arranged between the two locating holes 114. In addition, the mounting opening 1120 can be a rectangular opening. In this case, the two spaced-apart locating pins 13 can be fitted into the rectangular mounting opening 1120, thereby aligning the two spaced-apart mounting holes 114 with the mounting opening 1120, so that the two fasteners can pass through the two mounting holes 114 and the mounting opening 1120 respectively, thereby mounting the base 110 to the positioning plate 1100. As a result, the mounting opening 1120 and the mounting hole 114 can be accurately aligned, and the base 110 can be accurately and securely mounted to the positioning plate 1100.

[0081] like Figures 6-8 As shown in FIG. 12-17 , the driving member 131 is provided to at least one of the opposite side walls 111 of the base 110 and is connected to the first plate portion 121 to drive the first plate portion 121 to move between the opposite side walls 111 of the base 110 (e.g., along the Figure 4 The driving member 131 is configured to move the second plate portion 122 and the third plate portion 123, as well as the first and second sensors 211 and 212 mounted thereon. Furthermore, at least a portion of the driving member 131 is exposed from the outside of the base 110, for example, from at least one of the opposing side walls 111 of the base 110, so as to be manually or automatically operated to drive the sensor mounting plate 120 (e.g., the first plate portion 121) to move, as described in detail below.

[0082] In some embodiments, as Figures 6-8 As shown in Figure 12, the driving member 131 includes a driving screw 1311, both ends of which are rotatably arranged in the opposite side walls 111 of the base 110, the driving screw 1311 has an external thread, the first plate portion 121 has a first threaded hole 1211, the first threaded hole 1211 has an internal thread, the driving screw 1311 passes through the first threaded hole 1211, the internal thread and the external thread cooperate with each other, and the driving screw 1311 can be rotated under the action of external force to drive the first plate portion 121 to move along the driving screw 1311 through the cooperation between the internal thread and the external thread.

[0083] For example, the first end of the drive screw 1311 may be provided with a hexagonal protrusion or recess, so that a user can manually act on the first end of the drive screw 1311 using an internal or external hexagonal wrench to rotate the drive screw 1311. For another example, a motor may be connected to the first end of the drive screw 1311 to automatically rotate the drive screw 1311.

[0084] For another example, the second end of the drive screw 1311 may be provided with an annular groove, and the driver 131 further includes a stop ring 1317. The stop ring 1317 is disposed within the annular groove and protrudes radially outward from the annular groove. The stop ring 1317 abuts against the outer surface of the sidewall 111 of the base 110. Furthermore, the drive screw 1311 may include an annular step at its second end. For example, the diameter of the second end of the drive screw 1311 may be smaller than the diameter of the remaining portion, thereby forming the annular step. The driver 1311 further includes an adjustment washer 1316 disposed at the step and abutting against the inner surface of the sidewall 111 of the base 110. Thus, the second end of the drive screw 1311 is connected to the sidewall 111 of the base 110 and cannot move axially relative to the sidewall 111 of the base 110. However, the second end of the drive screw 1311 is still rotatable relative to the sidewall 111 of the base 110.

[0085] In some embodiments, the model of the driving screw 1311 can be M5x0.8, where M5 indicates that the nominal diameter of the screw is 5 mm, and 0.8 indicates that the pitch of the screw is 0.8 mm. Thus, if the driving screw 1311 rotates one circle, the sensor mounting plate 120 connected thereto moves 0.8 mm (left or right, such as Figure 4 Further, if the driving screw 1311 is rotated 1 / 8 turn (ie 45 degrees), the sensor mounting plate 120 connected thereto moves 0.1 mm (left or right, as shown).

Furthermore, the other end of the guide shaft 1321 has a stop flange 1325. The stop flange 1325 is located outside the sidewall 111 of the base 110 to prevent the guide shaft 1321 from being separated from the sidewall 111 of the base 110 at this end.

[0102] It is understandable that different embodiments of the driving member 131 and the guiding member 132 are described above. In the absence of contradiction, the different embodiments of the driving member 131 can be arbitrarily combined with the different embodiments of the guiding member 132.

[0103] The sensor assembly 200 according to the embodiment of the present invention includes the sensor position adjustment mechanism 100 according to the embodiment of the present invention and a sensor 210 . The sensor 210 is mounted on the sensor mounting plate 120 and is movable together with the sensor mounting plate 120 .

[0104] The coverslipping machine 1000 according to an embodiment of the present invention includes a bracket 1200 and a sensor assembly 200 according to an embodiment of the present invention. The bracket 1200 is used to accommodate a glass slide 1300 and move with the glass slide 1300. The sensor 210 is used to detect the bracket 1200 and / or the glass slide 1300.

[0105] When the sensor 210 mounted thereon deviates from the desired position through the sensor position adjustment mechanism 100, the driving device 130 can drive the sensor mounting plate 120, thereby causing the sensor 210 mounted thereon to move, thereby adjusting the position of the sensor 210 so that it is aligned with the desired position again. In this way, the sensor 210 can accurately identify the glass slide 1300 transferred to the desired position by the support 1200, allowing the gripping device 1400 (e.g., a robot) to grip the glass slide 1300 at the desired position for the next operation, such as sealing the glass slide 1300, i.e., applying a cover glass thereto.

[0106] In some embodiments, as Figure 1 and 2As shown, the coverslipper 1000 according to an embodiment of the present invention further includes a housing 1500 and a maintenance panel 1600. The housing 1500 has a maintenance port 1510. The sensor assembly 200 is disposed in the housing 1500 and located at the maintenance port 1510. The maintenance panel 1600 is connected to the housing 1500 and disposed at the maintenance port 1510 to cover the maintenance port 1510. The maintenance panel 1600 can be removed to expose the maintenance port 1510 and the sensor assembly 200 located at the maintenance port 1510. Thus, by removing the maintenance panel 1600, the sensor position adjustment mechanism 100 of the sensor assembly 200 can be conveniently operated to adjust the position of the sensor 210 so that it is preliminarily aligned with or realigned at a desired position.

[0107] Further, as described with respect to the sensor position adjustment mechanism 100 and the sensor assembly 200 according to the embodiment of the present invention, the coverslip machine 1000 according to the embodiment of the present invention further includes a gripping device 1400 and a positioning plate 1100. The gripping device 1400 is at least partially disposed in the housing 1500 and is used to grip the slide 1300 accommodated in the bracket 1200. The positioning plate 1100 is disposed in the housing 1500 and is installed at the maintenance port 1510. The sensor assembly 200 is mounted to the positioning plate 1100. The positioning plate 1100 has a positioning opening 1110. The positioning opening 1110 is aligned with the gripping device 1400. The sensor assembly 200 is located at the positioning opening 1110 and is aligned with the positioning opening 1110, so that the sensor assembly 200 is aligned with the gripping device 1400. In some embodiments, the sensor assembly 200, the positioning opening 1110, and the gripping device 1400 are aligned with each other. Figure 4 shown.

[0108] The present application also discloses a sensor position adjustment method, which uses the sensor position adjustment mechanism 100 according to an embodiment of the present utility model and includes the following steps.

[0109] In step S100 , the sensor 210 is aligned with the gripping device 1400 .

[0110] For example, the sensor position adjustment mechanism 100 is installed at the positioning opening 1110 of the positioning plate 1100, and the positioning opening 1110 is aligned with the gripping device 1400, so that the sensor position adjustment mechanism 100 and the sensor 210 located thereon are aligned with the gripping device 1400. It is understood that this step mainly occurs during the assembly process of the coverslipper 1000, but can also occur during the maintenance process of the coverslipper 1000.

[0111] In step S200 , the sensor 210 is preliminarily aligned with a desired position.

[0112] For example, the gripping device 1400, which has already grasped the glass slide 1300, is lowered to the grasping position. The sensor position adjustment mechanism 100 is then operated to adjust the position of the sensor 210 mounted thereon so that the light emitted by the sensor 210 illuminates the side of the glass slide 1300 grasped by the gripping device 1400. At this point, the glass slide 1300 is at the desired position, and the sensor 1300 is aligned with the desired position. In this way, whenever the sensor 210 detects that the glass slide 1300 has moved to the desired position, the support 1200 that transports the glass slide 1300 stops. In theory, the gripping device 1400 can grasp the glass slide 1300 at the desired position.

[0113] In step S300 , when the sensor 210 detects the glass slide 1300 , it is determined whether the gripping device 1400 can grip the glass slide 1300 .

[0114] Theoretically, whenever the sensor 210 detects the glass slide 1300, the gripping device 1400 can grip the glass slide 1300. However, in practice, the expected position (e.g., the current or actual gripping position of the gripping device 1400) may have errors. For example, the expected position may change. For example, the sensor 210 that has been preliminarily aligned in step S200 is not aligned with the current or actual gripping position of the gripping device 1400.

[0115] In step S400 , if the gripping device 1400 cannot grip the glass slide 1300 , the position of the sensor 210 is adjusted by the sensor position adjustment mechanism 100 so that the sensor 210 is aligned with the current gripping position of the gripping device 1400 .

[0116] If the gripping device 1400 fails to grip the glass slide 1300, this indicates that there is an error (or change) in the desired position, for example, there is an error between the current gripping position of the gripping device 1400 and the previous desired position. In this case, the sensor position adjustment mechanism 100 can be used to adjust the position of the sensor 210 so that the sensor 210 is aligned with the current gripping position of the gripping device 1400, thereby offsetting the error in the desired position. For example, the desired position is adjusted to the current gripping position of the gripping device 1400, ensuring that the gripping device 1400 can grip the glass slide 1300 detected by the sensor 210.

[0117] It can be understood that, for each slide 1300, it is determined whether the grabbing device 1400 can grab the slide 1300 when the sensor 210 detects the slide 1300. If the grabbing device 1400 can grab the slide 1300, the support 1200 continues to move to deliver the next slide 1300 to the desired position, and the determination is made again until the grabbing device 1400 cannot grab a certain slide 1300. In the case that the grabbing device 1400 cannot grab a certain slide 1300, the above adjustment can be made to update the desired position (for example, the desired position is updated in real time to the current grabbing position of the grabbing device 1400), so that the grabbing device 1400 can grab the slide 1300 again.
