Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a positioning device for processing microscope cover slips. Background Technology

[0002] A microscope coverslip positioning device is a specialized device designed to ensure precise positioning of coverslips during microscope slide processing. The main purpose of this device is to improve the accuracy of coverslip placement and ease of operation during microscope sample preparation, thereby ensuring sample quality and observation accuracy.

[0003] Microscope coverslips are a type of transparent glass or plastic sheet commonly used in microscope experiments. They are mainly used to cover the sample on the slide to protect the sample and provide a flat surface for observation under the microscope. During the processing of microscope coverslips, the edges need to be ground to ensure smoothness and improve safety in use.

[0004] In existing microscope cover slip processing, clamping is often used to fix the cover slip for positioning. While this method ensures the stability of the cover slip during processing, it also brings some inconveniences: if the relative position between the cover slip and the grinding device needs to be adjusted, the original clamping device must be removed and repositioned. This repeated disassembly and repositioning process is not only time-consuming and labor-intensive, but may also lead to a decrease in positioning accuracy, affecting processing efficiency and the quality of the final product. Therefore, a positioning device for microscope cover slip processing is proposed to address the above problems. Utility Model Content

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A positioning device for processing microscope coverslips includes a width adjustment component 6 and a positioning stage 1. A folding plate 2 is fixedly connected to the top of the positioning stage 1, and an electric telescopic rod 3 is fixedly connected to the inner side of the folding plate 2. A first positioning component 4 is fixedly connected to the bottom of the electric telescopic rod 3, and the bottom of the first positioning component 4 is attached to the top of the coverslip body 5. A second positioning component 7 is installed on the upper end of the width adjustment component 6. The width adjustment component 6 includes a support platform 61, with an internal groove 62 formed on the inner side of the upper end of the support platform 61. An electromagnet 63 is fixedly connected to the inner side of the internal groove 62 of the support platform 61. A first guide rod 64 is fixedly connected to the upper end of the support platform 61. A plastic... The material plate 65 has a sliding block 66 slidably connected to the outer side of the first guide rod 64, and a second guide rod 67 fixedly connected to the inner side of the moving block 66. A cylindrical hole 68 is opened on the inner side of the moving block 66. The second positioning component 7 includes an internal thread plate 71, a screw 72 spirally attached to the inner side of the internal thread plate 71, an adjusting block 73 fixedly connected to one side of the internal thread plate 71, a ball groove 75 fixedly connected to the top of the adjusting block 73, an outer rubber ball 74 installed inside the ball groove 76 opened in the ball groove 75, a steel ball 77 embedded in the inner side of the ball groove 75 near the ball groove 76, a spring 78 fixedly connected to the inner side of the adjusting block 73, and a concave arc iron plate 79 fixedly connected to the top of the spring 78.

[0029] As a further implementation of this solution, the front view shape of the folding plate 2 is L-shaped. The folding plate 2 has an installation hole on the inner side near the electric telescopic rod 3. The lower end of the first positioning component 4 is equipped with an outer rubber ball 74 and a steel ball 77. The center of the first positioning component 4 and the center of the width adjustment component 6 are on the same vertical line. The cooperation between the first positioning component 4 and the four second positioning components 7 can quickly clamp the cover glass body 5.

[0030] As a further implementation of this solution, the bottom end of the first positioning component 4 is attached to the top end of the cover glass body 5 via an outer rubber ball 74, and the top end of the outer rubber ball 74 installed on the second positioning component 7 is attached to the bottom end of the cover glass body 5. The number of outer rubber balls 74 is set to five. The setting of five outer rubber balls 74 not only protects the cover glass from damage, but also increases the friction.

[0031] As a further implementation of this solution, the bottom end of the support platform 61 is fixedly connected to the top end of the positioning machine platform 1. The front view shape of the support platform 61 is U-shaped. There are two first guide rods 64. The outer side of the first guide rod 64 is slidably connected to the inside of the cylindrical hole 68 opened in the moving block 66. The left and right ends of the second guide rod 67 are fixedly connected to the moving block 66. The moving block 66 has an installation hole on the inner side near the second guide rod 67. The outer side of the second guide rod 67 is slidably connected to the inner side of the adjusting block 73. The front and rear ends of the adjusting block 73 are fixedly connected to square plates. The inner side of the square plate of the adjusting block 73 has a sliding hole. By setting the width adjustment component 6, the position distribution of the four second positioning components 7 can be adjusted according to the size of the cover glass body 5, thereby adapting to most of the positioning work of the cover glass body 5.

[0032] As a further implementation of this solution, the bottom end of the adjusting block 73 is attached to the top end of the plastic plate 65, the bottom end of the screw 72 is attached to the top end of the plastic plate 65, the inner thread plate 71 has a threaded hole on the inner side near the screw 72, and the number of the second positioning components 7 is four, which are fixed by the screw 72.

[0033] As a further implementation of this solution, the inner side of the adjusting block 73 is provided with a groove, and the concave arc iron plate 79 is slidably connected to the inner side of the groove of the adjusting block 73. The top of the concave arc iron plate 79 is attached to the bottom of the outer rubber ball 74. The ball groove 75 is provided with a ball groove on the inner side near the steel ball 77. The steel ball 77 protrudes from the inside of the ball groove 76, and the outer side of the steel ball 77 is attached to the outer side of the outer rubber ball 74. When the electromagnet 63 is activated, the outer rubber ball 74 can move inside the ball groove 76. The friction of the outer rubber ball 74 when rotating can be reduced by setting multiple steel balls 77.

[0034] Workflow: After clamping the cover glass body 5, when the position of the cover glass body 5 can be moved without disassembling the device, first adjust the position of the four second positioning components 7 according to the size of the cover glass body 5. When the second guide rod 67 is pushed forward and backward, the second guide rod 67 drives the moving block 66 to move. The moving block 66 slides on the outside of the first guide rod 64 through the cylindrical hole 68, which plays a role in limiting the forward and backward movement of the second positioning components 7. When adjusting the left and right position of the second positioning components 7, the adjusting block 73 facilitates left and right sliding when the second positioning components 7 are pushed. On the outside of the second guide rod 67, after the positions of the four second positioning components 7 are adjusted, the screw 72 is rotated to press tightly against the top of the plastic plate 65. Under the action of friction, the second positioning components 7 are fixed. The cover glass body 5 is placed on the upper end of the four second positioning components 7. The electric telescopic rod 3 is then activated to push the first positioning component 4 downward. When the outer rubber ball 74 inside the first positioning component 4 is in contact with the upper end of the cover glass body 5, the positioning of the cover glass body 5 is completed. The outer rubber ball 74 is spherical in shape, and its outer surface is made of rubber while its inner surface is a hard ball. When the outer rubber ball 74 comes into contact with the cover glass body 5, it undergoes a certain deformation. The outer rubber ball 74 prevents damage to the cover glass body 5 while fixing it in place, and also increases the friction between them. Under the elastic force of the spring 78, the concave iron plate 79 is pushed to maintain contact with the outer rubber ball 74. The friction between the concave iron plate 79 and the outer rubber ball 74 prevents rotation. The positioning effect of the four outer rubber balls 74 at the lower end of the cover glass body 5 prevents displacement during processing, thus ensuring... To ensure the stability of the cover glass body 5 during processing, when the position of the cover glass body 5 needs to be moved, the electromagnet 63 is activated to generate magnetic force. The magnetic force of the electromagnet 63 passes through the plastic plate 65 and magnetically attracts the four concave arc iron plates 79. Under the action of magnetic attraction, the concave arc iron plates 79 slide and connect to the lower end of the adjusting block 73. After the concave arc iron plates 79 move away from the outer rubber ball 74, when the cover glass body 5 is moved, the outer rubber ball 74 will roll. The outer rubber ball 74 drives multiple steel balls 77 to roll. The steel balls 77 can reduce the friction when the outer rubber ball 74 rolls. After the adjustment is completed, the electromagnet 63 is de-energized.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
