Referring to fig. 1-3, a slide clamping device 100 of the present application includes a base 60, a motor 50, an elastic member 40, a rotating mechanism 30, a first clamping mechanism 10, and a second clamping mechanism 20. The holder body 60 is connected to the inside of the medical instrument, and the holder body 60 can be fixedly connected to the inside of the medical instrument and is only used for clamping the slide 200; the holder 60 is more in a state of being movably connected in the medical instrument, and also takes the task of taking out and transferring the slide 200 to the work line in the medical instrument after gripping the slide 200.

The motor 50 is fixedly connected with the base 60, the motor 50 includes an output shaft 51, and the rotating mechanism 30 is fixedly connected with the output shaft 51. It is understood that the motor 50 can rotate by driving the output shaft 51 to rotate the rotating mechanism 30 relative to the housing 60. The first clamping mechanism 10 and the second clamping mechanism 20 are symmetrically disposed on two sides of the rotating mechanism 30, and the first clamping mechanism 10 and the second clamping mechanism 20 are further respectively abutted against and in contact with two sides of the rotating mechanism 30. Specifically, in the embodiment of fig. 1, the first clamping mechanism 10 is slidably connected to the seat 60 along the first direction 001, and the second clamping mechanism 20 is also slidably connected to the seat 60 along the first direction 001, so that the first clamping mechanism 10 and the second clamping mechanism 20 can simultaneously slide relative to the seat 60 and move toward each other along the first direction 001 or move away from each other along the first direction 001. An elastic member 40 is further connected between the first clamping mechanism 10 and the second clamping mechanism 20, and the elastic member 40 is used for providing an elastic force for relatively approaching the first clamping mechanism 10 and the second clamping mechanism 20 along the first direction 001, so as to maintain the abutting and contacting states of the first clamping mechanism 10 and the second clamping mechanism 20 and the rotating mechanism 30.

When the slide glass gripping device 100 of the present application is in the non-operating state, the output shaft 51 of the motor 50 has no torque output, and the rotating mechanism 30 only receives the pressing force applied from both sides by the first gripping mechanism 10 and the second gripping mechanism 20, which comes from the elastic member 40 connected between the first gripping mechanism 10 and the second gripping mechanism 20. At this time, the first clamping mechanism 10 and the second clamping mechanism 20 are close to each other with the minimum distance therebetween or are in direct contact with each other under the elastic force of the elastic member 40. While the rotary mechanism 30 is in the first rotational position.

When the slide clamping device 100 of the present application needs to clamp the slide 200, as shown in fig. 2, the motor 50 drives the output shaft 51 to rotate and drives the rotating mechanism 30 to rotate synchronously. The rotation mechanism 30 turns from the first rotation posture to the second rotation posture. At this time, the rotating mechanism 30 is driven by the motor 50 to simultaneously form a supporting force on the first clamping mechanism 10 and the second clamping mechanism 20, and the supporting force is greater than the elastic force of the elastic member 40, so that the first clamping mechanism 10 and the second clamping mechanism 20 are relatively separated and pushed away along the first direction under the action of the rotating mechanism 30, and a gap 01 is formed between the first clamping mechanism 10 and the second clamping mechanism 20. This gap 01 is larger than the outer dimension of the slide 200, in this embodiment, expressed as the thickness dimension of the slide 200, so that the slide clamp device 100 can spread the first and second clamp mechanisms 10 and 20 to prepare for clamping the slide 200.

Referring to fig. 3, when the slide clamping device 100 clamps the slide 200, the rotating mechanism 30 is driven by the motor 50 to rotate from the second rotating posture to the third rotating posture, and the first clamping mechanism 10 and the second clamping mechanism 20 are moved toward each other again in the first direction 001 in the third rotating posture of the rotating mechanism 30 and are respectively brought into contact with the slide 200 from both sides of the slide 200, so that the first clamping mechanism 10 and the second clamping mechanism 20 jointly act on the slide 200 and form a clamping action. Subsequently, the slide 200 is transported to the working line of the medical instrument by the slide gripper 100 of the present application to be subjected to staining, analysis, and the like.

The slide clamping device 100 of the present application does not adopt a scheme of pneumatically clamping the slide 200 similar to the prior art, but adopts a motor drive to assist the elastic member 40 to provide elastic force to clamp the slide 200. Due to the arrangement, after the power of the motor 50 is lost accidentally, the first clamping mechanism 10 and the second clamping mechanism 20 can still keep the clamping state of the slide 200 under the action of the elastic piece 40, the phenomenon that the slide 200 is damaged due to accidental falling or even stuck inside a medical instrument is avoided, and the reliability of the operation of clamping the slide 200 is improved. On the other hand, the slide clamping device 100 saves the arrangement of the air path, the problem of air tightness in the moving assembly is not needed to be solved, and the reliability of the medical instrument is further improved under the condition that the internal structure of the medical instrument is simplified.

It is understood that, in the first rotation posture and the third rotation posture of the rotation mechanism 30, the first clamping mechanism 10 and the second clamping mechanism 20 are in a relatively close state. And in some embodiments, it is also possible to set the first and third rotational postures of the rotating mechanism 30 to be turned by the same angle, that is, the gap 01 between the first and second gripping mechanisms 10 and 20 is exactly equal to the thickness dimension of the slide 200 when the slide gripping device 100 of the present application is in the non-operating state. When the rotating mechanism 30 is in the second rotating posture, the first clamping mechanism 10 and the second clamping mechanism 20 are pushed away by the rotating mechanism 30, and the distance between the two becomes relatively large.

On the other hand, when the slide gripper 100 of the present application is gripping the slide 200, the output shaft 51 can be driven to rotate by the motor 50, so as to drive the rotating mechanism 30 to rotate from the second rotating posture to the third rotating posture. At this time, since the elastic member 40 also provides an elastic force to the first clamping mechanism 10 and the second clamping mechanism 20 to be relatively close to each other, the rotating mechanism 30 is actually driven by the resultant force of the motor 50 and the elastic member 40 to rotate from the second rotating posture to the third rotating posture. In other embodiments, the motor 50 may also be used only to drive the rotation mechanism 30 to rotate from the first rotation posture to the second rotation posture, that is, the motor 50 is used only to drive the rotation mechanism 30 to support the first clamping mechanism 10 and the second clamping mechanism 20. When the rotating mechanism 30 rotates from the second rotating posture to the third rotating posture, the motor 50 may not output torque, and only through the action of the elastic member 40, the first clamping mechanism 10 and the second clamping mechanism 20 are driven to move closer to each other, and abut against the rotating mechanism 30 to rotate from the second rotating posture to the third rotating posture.

In the slide gripping device 100 of the present application, a cam-slider type mechanism is employed to perform the closing-separating-closing actions of the first gripper mechanism 10 and the second gripper mechanism 20 to grip the slide 200. It is understood that in other implementations, the rotating mechanism 30 may be provided as a gear, and the first clamping mechanism 10 and the second clamping mechanism 20 are respectively provided with a rack engaged with the gear, so as to clamp the slide 200.

In one embodiment, the rotating mechanism 30 is symmetrically provided with a first abutting portion 31 and a second abutting portion 32 along the axis 511 of the output shaft 51, wherein the first abutting portion 31 contacts and abuts against the first clamping mechanism 10, and the second abutting portion 32 contacts and abuts against the second clamping mechanism 20. When the rotating mechanism 30 rotates from the first rotating posture to the second rotating posture, the distance between the first abutting portion 31 and the axis 511 along the first direction 001 gradually increases to abut against and push away the first clamping mechanism 10; correspondingly, the distance of the second abutting portion 32, which is symmetrically arranged with respect to the first abutting portion 31, from the axis 511 along the first direction 001 is gradually increased, and the second clamping mechanism 20 is abutted and pushed away. It is understood that, when the rotating mechanism 30 rotates from the second rotation posture to the third rotation posture, the distance between the first abutting portion 31 and the second abutting portion 32 with respect to the axis 511 gradually decreases, so that the first clamping mechanism 10 and the second clamping mechanism 20 can be drawn together toward each other.

On the other hand, the first abutting portion 31 and the second abutting portion 32 are symmetrically arranged, so that the first clamping mechanism 10 and the second clamping mechanism 20 can always keep a state of symmetrically sliding in the first direction 001 relative to the rotating mechanism 30. In the process that the rotating mechanism 30 rotates from the first rotating posture to the second rotating posture, the first clamping mechanism 10 and the second clamping mechanism 20 are pushed away along the first direction 001 symmetrically relative to the rotating mechanism 30 under the action of the first abutting part 31 and the second abutting part 32 which are symmetrically arranged; in the process that the rotating mechanism 30 rotates from the second rotating posture to the third rotating posture, the first clamping mechanism 10 and the second clamping mechanism 20 are symmetrically closed along the first direction 001 relative to the rotating mechanism 30 under the action of the first abutting portion 31 and the second abutting portion 32 which are symmetrically arranged.

Therefore, the first gripper mechanism 10 and the second gripper mechanism 20 are always kept symmetrical with respect to the rotating mechanism 30, and during the operation of the slide gripper 100 of the present application, if the rotation center of the rotating mechanism 30 is aligned with the geometric center of the slide 200, the relative movement of the first gripper mechanism 10 and the second gripper mechanism 20 with respect to the geometric center of the slide 200 can be ensured. Namely, the first clamping mechanism 10 and the second clamping mechanism 20 can symmetrically clamp the slide 200, and the geometric center of the slide 200 is always coincident with the geometric center of the rotating mechanism 30, so that the slide 200 can be accurately positioned in the subsequent operation of taking out and transferring the slide 200 to the working line.

In one embodiment, corresponding to the first abutting portion 31, the first clamping mechanism 10 includes a first abutting surface 11 facing the rotating mechanism 30, and the first abutting portion 31 abuts against the first abutting surface 11 to push away the first clamping mechanism 10; the second clamping mechanism 20 is also provided with a second abutting surface 21 opposite to the first abutting surface 11, and the second abutting portion 32 abuts against the second abutting surface 21 to push the second clamping mechanism 20 open. The first abutting surface 11 may be an outer sidewall of the first clamping mechanism 10 facing the rotating mechanism 30, and the second abutting surface 21 may also be an outer sidewall of the second clamping mechanism 20 facing the rotating mechanism 30. That is, the first abutting portion 31 of the rotating mechanism 30 abuts against the outer sidewall of the first clamping mechanism 10 to push the first clamping mechanism 10 away along the first direction 001, and the second abutting portion 32 of the rotating mechanism 30 abuts against the outer sidewall of the second clamping mechanism 20 to push the second clamping mechanism 20 away along the first direction 001.

In one embodiment, in order to improve the working efficiency of the motor 50, the motor 50 may be a bidirectional motor, and the motor 50 drives the rotating mechanism 30 to rotate back and forth alternately by driving the output shaft 51, so as to drive the first clamping mechanism 10 and the second clamping mechanism 20 to move toward each other or move away from each other, thereby achieving the action of clamping or releasing the slide 200.

As can be seen from the schematic diagram of fig. 4, a first included angle α is formed between a connection line between the first abutting portion 31 and the second abutting portion 32 and the first direction 001. When the rotating mechanism 30 rotates, a component force of a thrust force provided by the first abutting portion 31 to the first clamping mechanism 10 in the first direction 001 increases with an increase of the first included angle α, and a displacement component formed by the rotating mechanism 30 to the first clamping mechanism 10 in the first direction 001 also increases with an increase of the first included angle α. That is, when the rotating mechanism 30 is rotated from the first rotational posture to the second rotational posture, the thrust force in the first direction 001 with respect to the first clamping mechanism 10 is gradually reduced, and the displacement in the first direction 001 with respect to the first clamping mechanism 10 is also gradually reduced. When the first included angle α is continuously smaller, the output power of the motor 50 needs to be correspondingly increased in order to ensure the thrust force to the first clamping mechanism 10 and the second clamping mechanism 20 by the rotating mechanism 30. Under the condition that the output power of the motor 50 is constant, in order to ensure that the rotating mechanism 30 effectively pushes the first clamping mechanism 10 and the second clamping mechanism 20 away, the maximum rotating angle of the rotating mechanism 30 can be limited, so that the output power of the motor 50 can be more effectively converted into the thrust of the rotating mechanism 30 to the first clamping mechanism 10 and the second clamping mechanism 20 and form the displacement of the first clamping mechanism 10 and the second clamping mechanism 20, and the motor 50 is prevented from driving the rotating mechanism 30 in the range with the relatively small first included angle α, which causes power waste.

Therefore, the two-way motor can make the motor 50 control the rotation mechanism 30 to rotate back and forth within a more effective angle range, so as to improve the working efficiency of the motor 50 and correspondingly reduce the rated power of the motor 50. In one embodiment, the maximum rotation angle of the output shaft 51 may be limited to be less than or equal to 70 degrees, i.e., the first included angle α is limited to be between 20 degrees and 90 degrees, and preferably, the maximum rotation angle of the output shaft 51 is limited to be less than or equal to 45 degrees, so as to limit the first included angle α to be between 45 degrees and 90 degrees, which can improve the output efficiency of the motor 50.

In another embodiment, the first clamping mechanism 10 further has a first slide rail 12, and the first abutting surface 11 is configured as an inner wall of one side of the first slide rail 12. It is understood that the first abutting surface 11 is configured as a side inner wall of the first slide rail 12 facing the rotating mechanism 30. The first abutting portion 31 extends into the first slide rail 12 to abut against the first abutting surface 11; the second clamping mechanism 20 is also provided with a second slide rail 22, the second abutting surface 21 is configured as an inner wall of one side of the second slide rail 22 facing the rotating mechanism 30, and the second abutting portion 32 extends into the second slide rail 22 to abut against the second abutting surface 21.

Referring to fig. 5, the first abutting portion 31 includes a first extending section 311, and the first extending section 311 extends into the first slide rail 12 to abut against the first abutting surface 11. By setting the size of the first extending section 311 along the first direction 001 to match with the width size of the first slide rail 12, the first clamping mechanism 10 can also provide a third abutting surface 13 opposite to the first abutting surface 11 to abut against the first extending section 311, so that when the first clamping portion 31 rotates from the second rotation posture to the third rotation posture, the third abutting surface 13 can also abut against the first clamping mechanism 10 to pull the first clamping mechanism 10 back to a position close to the rotation mechanism 30. Correspondingly, the second slide rail 22 is also arranged to enable the second abutting portion 32 to pull the second clamping mechanism 20 back to a position close to the rotating mechanism 30. That is, the first gripper mechanism 10 and the second gripper mechanism 20 can be driven by the rotating mechanism 30 to move toward each other and form a gripping force on the slide 200.

Corresponding to the embodiment of fig. 5, since the rotating mechanism 30 can provide the pushing force for both holding and driving the movement to the first and second gripping mechanisms 10 and 20 throughout the operation of the slide gripping device 100, the elastic member 40 can also be provided between the rotating mechanism 30 and the motor 50 in this embodiment, i.e., the elastic member 40 is provided as a torsion spring. The elastic member 40 configured as a torsion spring can be elastically deformed when the rotating mechanism 30 is driven by the motor 50 to rotate from the first rotating posture to the second rotating posture, and can provide an elastic force to the rotating mechanism 30 when the rotating mechanism 30 rotates from the second rotating posture to the third rotating posture, so as to provide an elastic force for relatively approaching the first clamping mechanism 10 and the second clamping mechanism 20 along the first direction 001 by the abutting of the first abutting portion 31 and the second abutting portion 32 against the first slide rail 12 and the second slide rail 22, respectively. It can be understood that, when the slide clamping device 100 clamps the slide 200, if the motor 50 is suddenly powered off, the first clamping mechanism 10 and the second clamping mechanism 20 can still effectively clamp the slide 200 by the elastic force provided by the elastic member 40 in the form of the torsion spring, so as to prevent the slide 200 from accidentally dropping.

Whereas in the embodiment of fig. 1-3 the elastic member 40 is connected between the first clamping mechanism 10 and the second clamping mechanism 20, the elastic member 40 is provided as a tension spring. In other embodiments, the elastic member 40 may also be configured as a compression spring. Specifically, referring to fig. 6, the elastic member 40 includes a first elastic member 41 and a second elastic member 42, wherein the first elastic member 41 is connected between the first clamping mechanism 10 and the seat 60, the second elastic member 42 is connected between the second clamping mechanism 20 and the seat 60, the first elastic member 41 is compressed when the first clamping mechanism 10 is pushed away from the rotating mechanism 30, meanwhile, the second elastic member 42 is also compressed when the second clamping mechanism 20 is pushed away from the rotating mechanism 30, and the first elastic member 41 and the second elastic member 42 respectively provide elastic forces to the first clamping mechanism 10 and the second clamping mechanism 20 when the first clamping mechanism 10 and the second clamping mechanism 20 are moved toward each other.

In one embodiment, the slide gripper 100 further includes a sensor 70. The sensor 70 is used to sense whether the slide 200 is gripped between the first gripper mechanism 10 and the second gripper mechanism 20. There are many embodiments in the art to perform the function of the sensor 70, such as an infrared ranging sensor, a proximity sensor, and the like.

In the embodiment of fig. 1-3, the sensor 70 is implemented by means of a light coupling sensor 71 cooperating with a shutter 72. The optical coupler sensor 71 is fixedly connected with the base 60, the baffle 72 is fixedly connected with the first clamping mechanism 10, and the position of the baffle 72 corresponds to the position of the optical coupler sensor 71. When the rotating mechanism 30 is in the first rotating posture or the third rotating posture, the first clamping mechanism 10 is in a relatively close state with respect to the rotating mechanism 30, and at this time, the baffle 72 fixedly connected to the first clamping mechanism 10 also approaches the rotating mechanism 30 along with the first clamping mechanism 10. The position of the optical coupling sensor 71 is blocked by the blocking plate 72, and it can be judged that the slide clamping device 100 of the present application is in the non-operating state or the state of clamping the slide 200, and the relative distance between the first clamping mechanism 10 and the second clamping mechanism 20 is short.

When the motor 50 starts to work and the driving rotating mechanism 30 rotates to the second rotating state, the first clamping mechanism 10 is pushed away by the rotating mechanism 30, the baffle 72 is correspondingly pushed away from the optical coupler sensor 71, and at this time, the baffle 72 does not shield the optical coupler sensor 71 fixed on the seat body 60. The relative distance between the first gripper mechanism 10 and the second gripper mechanism 20 is now relatively large. The operating state of the slide clamp apparatus 100 can be judged by the sensing of the photo-coupler sensor 71.

In one embodiment, the slide gripper 100 further includes an alarm (not shown). The alarm is used for giving an alarm when the motor 50 loses steps. Specifically, with reference to the illustration of fig. 7, the slide gripping device 100 can determine whether the motor 50 has lost steps by detection of the sensor 70. When the slide gripper 100 is activated, the first gripper mechanism 10 and the second gripper mechanism 20 are relatively close to each other, and the optical coupler sensor 71 is shielded by the shutter 72. If the slide gripper 100 grips the slide 200, the motor 50 needs to rotate 10 steps to rotate the rotation mechanism 30 to the second rotation posture. If the slide gripper 100 is not gripping the slide 200, the motor 50 needs to rotate 12 steps to rotate the rotation mechanism 30 to the second rotational posture. As mentioned above, when the rotating mechanism 30 is in the second rotating posture, the baffle 72 does not block the optical coupling sensor 71. Therefore, after the motor 50 rotates by the corresponding number of steps, if the baffle 72 still shields the optical coupling sensor 71, it can be determined that the motor 50 loses steps, and the alarm can give an alarm to prompt the user to handle the fault.

Referring to fig. 8, the first clamping mechanism 10 has a first clamping portion 14 at an end away from the rotating mechanism 30, the second clamping mechanism 20 has a second clamping portion 24 at an end away from the rotating mechanism 30 corresponding to the first clamping portion 14, and the first clamping portion 14 and the second clamping portion 24 cooperate to clamp the slide 200. The first clamping portion 14 and the second clamping portion 24 respectively move along with the first clamping mechanism 10 and the second clamping mechanism 20, and by cooperatively setting the relative distance between the first clamping portion 14 and the second clamping portion 24, a better clamping effect can be achieved on the slide 200.

Further, in the schematic of fig. 8, the first clamping mechanism 10 includes two first clamping portions 14 arranged along a second direction 002 perpendicular to the first direction 001, and the corresponding second clamping mechanism 24 includes a second clamping portion 24 corresponding to the two first clamping portions 14 in one-to-one manner, that is, two pairs of first clamping portions 14 and second clamping portions 24 are respectively matched to simultaneously clamp two slide sheets 200. In this embodiment, the distance between the two first clamping portions 14 along the second direction 002 can be set by referring to the distance when the two slide slides 200 are stored, so that in the process of the first clamping mechanism 10 and the second clamping mechanism 20 closing together in opposite directions, the two pairs of first clamping portions 14 and the second clamping portions 24 respectively clamp one slide 200, and then the two slides 200 are simultaneously operated, and the working efficiency of the slide clamping device 100 can be improved.

It is understood that in the other embodiments, more than two first clamping parts 14 and second clamping parts 24 corresponding to each other in position may be further provided along the second direction 002, so as to realize batch processing of more slides 200 and improve the working efficiency of the slide clamping device 100 of the present application.

Referring to fig. 9, in view of manufacturing tolerances between different slides 200, when the slide clamping device 100 clamps a plurality of slides 200 in a batch, a portion of the slide 200 with a thin size may not be reliably clamped. For this purpose, the first clamping mechanism 10 further includes a fine adjustment device 15, the first clamping portion 14 is elastically connected to the first clamping mechanism 10 along the first direction 001 through the fine adjustment device 15, and the fine adjustment device 15 adapts to tolerance variation of the slide 200 through elastic deformation, so as to achieve the effect of adjusting the distance between the first clamping portion 14 and the second clamping portion 24.

Specifically, the fine adjustment device 15 includes a guide 151 and a fine adjustment spring 152, the guide 151 and the fine adjustment spring 152 are both disposed along the first direction 001, the guide 151 is used for limiting the sliding of the first clamping portion 14 along the first direction 001 relative to the first clamping mechanism 10, the fine adjustment spring 152 is disposed between the first clamping mechanism 10 and the first clamping portion 14, when the first clamping portion 14 cooperates with the second clamping portion 24 to clamp the corresponding slide 200, the first clamping portion 14 slides along the first direction 001 under the action of the guide 151 to adapt to the size of the slide 200, and maintains the abutting force on the slide 200 under the action of the fine adjustment spring 152, thereby achieving the effective clamping on the slide 200.

Further, in order to limit the fine adjustment distance of the first clamping portion 14 in the first direction 001, the fine adjustment device 15 further includes a limiting member 153, and the limiting member 153 is used for abutting against the first clamping portion 14 to achieve the effect of limiting the maximum sliding distance of the first clamping portion 14 relative to the first clamping mechanism 10. Since the manufacturing tolerance of the slide 200 is not large, and the fine adjustment distance of the first clamping portion 14 is too large, which tends to cause insufficient or too large elastic force of the fine adjustment spring 152, the limiting member 153 is used to limit the maximum sliding distance of the first clamping portion 14 relative to the first clamping mechanism 10, so as to ensure that an effective clamping force is formed between the first clamping portion 14 and the second clamping portion 24.

By counting the dimensional tolerances of the slide 200, one embodiment, setting the maximum sliding distance of the first clamping portion 14 and the first clamping mechanism 10 to be less than or equal to 0.6mm, can ensure that the slide clamping mechanism 100 of the present application can form an effective clamping force for most slides 200.

The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
