Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of slide clamping, particularly to a structure capable of improving the stability of slide clamping. BACKGROUND

[0002] In many fields such as medical treatment and scientific research, slides are often operated, and the accurate clamping of slides is crucial in processes such as microscopic observation and sample preparation. For example, in the medical field, the slide clamping equipment commonly used by medical staff is clamped from the wide end. This clamping method is prone to block the information and number on the slide for recording samples, which is not convenient for the equipment to accurately and quickly read. Another way is to clamp from the narrow end. In this clamping method, it is difficult to accurately control the clamping point, and the slide is prone to shift. Therefore, there is an urgent need for a slide clamping structure to solve the problem of equipment not being able to identify information when clamping a slide, and to improve the accuracy and stability of slide clamping. SUMMARY

[0003] To solve the above technical problems, the utility model provides a structure capable of improving the stability of slide clamping.

[0004] The technical scheme of the utility model is as follows: a clamping assembly and a driving device are included. The output end of the driving device is drivingly connected to two groups of parallel fingers that can move relative to each other. The clamping assembly includes two clamping jaws connected to the parallel fingers respectively. The opposite end faces of the two clamping jaws are provided with grooves for clamping slides. The bottom of the groove is provided with a buffer pad.

[0005] Further, the groove is U-shaped, and the groove has a bearing plane for supporting the slide.

[0006] Further, a guide slope is provided on the clamping jaw. The guide slope is located at the edge of the groove and forms a transition area for the slide entering the groove.

[0007] Further, a positioning structure is further provided between the two clamping jaws. When the slide is in a clamped state, one end of the slide is in contact with the positioning structure.

[0008] Further, the positioning structure is a stop block that extends towards the opposite end faces of the two clamping jaws.

[0009] Further, a control module and a sensor are further included, which are electrically connected. The sensor is located between the two clamping jaws and feeds back to the control module in real time whether the clamping jaw is in an empty state.

[0010] Further, the driving device includes a motor housing and a motor assembly arranged in the motor housing. The clamping assembly is arranged at the end of the motor housing and connected to the motor assembly.

[0011] Further, the buffer pad is a silica gel pad fixed to the bottom of the groove by pasting.

[0012] The beneficial technical effects of the utility model are: through the U-shaped groove design of the opposite end surface of the clamping jaw, the displacement of the slide is limited in multiple directions, and the stability of clamping is improved; the setting of the buffer pad in the U-shaped groove avoids the risk of slide edge collapse or falling caused by hard contact between the clamping jaw and the slide; the antiskid performance of the buffer pad further optimizes the clamping stability, so that clamping is more stable; the control module accurately controls the operation of the motor assembly through the real-time feedback signal of the sensor, ensures that every action of the whole structure is accurate and smooth, and runs smoothly. The overall structure is convenient to assemble and easy to operate, and realizes efficient and stable slide clamping effect. BRIEF DESCRIPTION OF DRAWINGS

[0018] In the embodiment, the upper end surface of the motor housing is fixed on a mounting plate 4 by screws, and the output end of the motor assembly is drivingly connected to two groups of parallel fingers 31 which are movable relative to each other; the clamping assembly 3 comprises two clamping jaws 32 which are fixedly connected to the two groups of parallel fingers 31, and the opposite end surfaces of the two clamping jaws 32 are both provided with a groove 33 for clamping a slide, the groove 33 is in a U shape, and the U-shaped groove 33 has a bearing plane for supporting the slide.

[0019] Further, the clamping jaw 32 is provided with a guide inclined surface 34 which is located at the edge of the groove 33 and forms a transition area for the slide entering the groove 33. During the clamping process of the clamping jaw 32, since there may be a certain deviation in the placement position of the slide, the guide inclined surface 34 can automatically adjust the slide to the appropriate position when the slide is clamped, so as to ensure that the slide can accurately enter the groove 33, thereby playing a role of guiding and correcting the position of the slide, and ensuring the stable and accurate clamping of the clamping jaw 32 on the slide.

[0020] Further, a buffer pad 35 is arranged in the groove 33, and the buffer pad 35 is elastically deformed to buffer the pressure of the clamping jaw 32 on the slide, so as to avoid the risk of the slide being clamped and broken compared to hard contact, and the friction force on the surface of the buffer pad 35 also reduces the possibility of the slide falling off. In the embodiment, the buffer pad 35 is a silica gel pad which is fixed to the bottom of the groove 33 by pasting.

[0021] Further, the clamping jaw 32 is also provided with a positioning structure 36, and when the slide is in a clamped state, one end of the slide is in contact with the positioning structure 36. The positioning structure 36 is used for accurately positioning the slide, so as to clearly limit the position of the slide in the groove 33, and ensure that the position of the slide is consistent when the clamping jaw 32 clamps the slide each time. In the embodiment, the positioning structure 36 is a stop block which is located between the two clamping jaws 32 and is connected to one of the clamping jaws 32; preferably, the opposite end surfaces of the two clamping jaws 32 are both provided with a stop block which extends in opposite directions, and the stop block can also prevent the slide from being displaced in the groove 33.

[0022] The sensor 2 is located between the two clamping jaws 32, and the sensor 2 is arranged on the lower end surface of the mounting plate 4 by a sensor fixing seat. In the embodiment, the sensor 2 is an optical fiber sensor which is used for detecting whether the clamping jaw 32 clamps the slide in real time, and feeding back a signal to a control module; when the optical fiber sensor detects that the clamping jaw 32 is in an empty state, the control module will pause the running program related to the clamping jaw 32, so as to avoid the clamping jaw 32 running in an empty state.
