[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model.

[0026] like Figure 1 , 2 As shown, the automatic sealing device mainly includes a conveying platform 2, an adsorption mechanism 1 and a gluing mechanism; the conveying platform 2 is the basic structure of the equipment, and a horizontal guide rail 21 is arranged on the conveying platform 2, and its function is to provide a flat surface for placing and conveying the slides 6 and cover slips to be sealed, and the adsorption mechanism 1 is the core part of the equipment, and the adsorption mechanism 1 includes a main sliding bracket 11, and the main sliding bracket 11 is arranged on the horizontal guide rail 21. In order to realize the sliding movement of the main sliding bracket 11, the conveying platform 2 is also equipped with a belt transmission assembly 22, and the belt transmission assembly 22 transmits power to the main sliding bracket 11 through a driving device, so that it can move horizontally on the conveying platform 2.

[0027] The adsorption mechanism 1 also includes a first suction cup structure 12, a second suction cup structure 13, a first vertical guide rail 16, a second vertical guide rail 17 and a detection device 14. The first vertical guide rail 16 and the second vertical guide rail 17 are arranged in parallel on the main sliding bracket 11. The first suction cup structure 12 and the second suction cup structure 13 are respectively installed on the first vertical guide rail 16 and the second vertical guide rail 17 of the main sliding bracket 11. They realize the lifting movement of the suction cup through the lifting drive assembly 15. This design can adjust the height of the first suction cup structure 12 and the second suction cup structure 13 separately as needed. The detection device 14 is located between the first suction cup structure 12 and the second suction cup structure 13, and is used to detect the thickness and damage state of the cover glass. This device can adopt a variety of technologies, such as laser scanning, ultrasonic detection or optical interference. Through precise detection, problems with the cover glass can be discovered in time to ensure the sealing quality and work efficiency.

[0028] This automatic film sealing device uses a cylinder as a lifting drive component 15, and a cylinder is respectively arranged on the first vertical guide rail 16 and the second vertical guide rail 17, and the telescopic end of the cylinder is connected to the corresponding first sliding bracket 18 or the second sliding bracket 19 to realize the lifting movement of the suction cup; specifically, the first sliding bracket 18 is provided with a first suction cup 121 and a first suction pipe 122, and the first suction cup 121 is located at the lower end of the first suction pipe 122, and the second sliding bracket 19 is provided with a second suction cup 131 and a second suction pipe 132 that are connected to each other, and the second suction cup 131 is located at the lower end of the first suction pipe 122. At the lower end of the second suction pipe 132, the upper ends of the first suction pipe 122 and the second suction pipe 132 are both connected to the negative pressure generating device. Switch valves are respectively provided on the first suction pipe 122 and the second suction pipe 132 for controlling the switch of the negative pressure. At the same time, the automatic sealing device is also equipped with a control device for controlling the operation of each component. The control device is connected to the switch valve signal and can adjust the on and off of the first suction pipe 122 and the second suction pipe 132 as needed, thereby determining whether the first suction cup 121 and / or the second suction cup 131 is adsorbed or not, so as to better complete the adsorption and sealing work.

[0029] Preferably, both the first suction cup 121 and the second suction cup 131 adopt an accordion suction cup structure, which can be extended and retracted according to the shape and size of the adsorbed object during operation. Such a suction cup is usually composed of a plurality of flexible folds. When negative pressure is applied to the suction cup, the folds will stretch and fit onto the surface of the adsorbed object, thereby achieving a firm adsorption effect. After the negative pressure stops, the suction cup can automatically retract, thereby quickly and conveniently releasing the adsorbed object.

[0030] The advantage of this design is that, combined with the attached Figure 4 As shown, since there may be adhesion between the cover glass slips 8, direct suction may cause them to be unable to be separated. When the cover glass slip 8 needs to be peeled off, the device will allow one of the first suction cup structure 12 and the second suction cup structure 13 to slide to produce an upper and lower height difference, thereby bending the cover glass slip 8 when sucking it from the cover glass slip storage bin. This bending action can destroy the adhesion between the cover glass slips 8, making them easier to separate. By adjusting the relative position and height difference of the suction nozzle, the device can control the degree of bending of the cover glass slip 8 according to different situations to achieve the best peeling effect, which can improve the working efficiency and sealing quality of the equipment, reduce the workload of the operator, and improve the overall production efficiency.

[0031] The last is the glue adding mechanism, combined with the attached Figure 3As shown, it is the part used to apply glue to the glass slide 6. The glue adding mechanism is arranged on the conveying platform 2 so as to automatically add glue to the glass slide 6 in the process of advancing. The glue adding mechanism mainly includes a material bottle, a plunger pump 5, a glue dropping probe 3 and a micrometer balance 4. The material bottle is a container for storing the sealing agent. The material bottle is usually located on one side of the equipment and is connected to the plunger pump 5. The plunger pump 5 is a device for conveying the sealing agent from the material bottle to the glue dropping probe 3. It realizes the suction and pushing functions of the sealing agent through the up and down movement of the plunger. The plunger pump 5 is driven by a motor and converts the rotational motion into linear motion through the connecting rod and the crankshaft. When running, the plunger of the plunger pump 5 will create negative pressure in the material bottle, absorb the sealing agent, and then add glue when it is needed. , the plunger will push downwards and push the sealing agent to the glue-drip probe 3. The glue-drip probe 3 is located at the end of the glue-adding mechanism and is used to apply the sealing agent on the glass slide 6. It is connected to the plunger pump 5 so that the sealing agent can be accurately delivered to the glass slide surface through the glue-drip probe 3. The glue-drip probe 3 usually has an adjustable glue application amount, which can be adjusted as needed; the micrometer balance 4 is a device for weighing the weight of the sealing agent. It is located on the conveying platform 2 and is used to place the glass slide 6 to be sealed. During the glue-adding process, the micrometer balance 4 will measure the weight of the sealing agent to achieve accurate glue addition control. The control device will adjust the operating speed of the plunger pump 5 according to the reading of the micrometer balance 4 to ensure accurate control of the glue addition amount. Among them, the measurement method of the micrometer balance 4 can be as follows Figure 3 As shown, the micrometer balance 4 is located below the conveying platform 2. The conveying platform 2 conveys the glass slide 6 to the micrometer balance 4, and then the lifting mechanism 7 controls the conveying platform to descend. The glass slide 6 can be placed on the micrometer balance 4 and the weight is measured by the micrometer balance 4. Then the gluing mechanism drips the sealing agent, so that the micrometer balance 4 can accurately detect the sealing agent to achieve accurate control of the amount of glue added. After the gluing is completed, the conveying platform 2 can be controlled to rise by the lifting mechanism 7 to continue to convey the glass slide 6.

[0032] More specifically, the plunger pump 5 is a back-suction plunger pump 5, also known as a reciprocating plunger pump 5. Its design principle is based on the fact that when the plunger moves up and down, negative pressure or positive pressure is generated inside the plunger, thereby achieving the suction and push of the liquid. The general structure of the back-suction plunger pump 5 is introduced as follows: the back-suction plunger pump 5 is usually composed of a plunger, a plunger rod, a sealing device and a pump body. The plunger is connected to the plunger rod, and the suction and push of the liquid are achieved through reciprocating motion. The sealing device is located between the pump body and the plunger to ensure that the liquid does not leak. The working principle of the back-suction plunger pump 5 is very simple. When the plunger moves upward, the volume inside the plunger increases to form a negative pressure area. At this time, the sealing device will prevent air from entering the pump body, while the liquid enters the negative pressure area through the inlet to achieve suction. When the plunger moves downward, the volume inside the plunger decreases to form a positive pressure area. At this time, the sealing device will prevent the liquid from flowing back, and the liquid will be pushed out through the outlet. As the prior art, the specific structure of the plunger pump 5 can be adaptively selected, including patent CN210503390U, etc., which can be a kind of back-suction plunger pump 5 in the utility model, and no specific limitation is made here.

[0033] The working principle of the glue adding mechanism is as follows: first, the sealing agent is stored in the material bottle, and the plunger pump 5 realizes the transportation of the sealing agent by connecting to the material bottle and the glue dropping probe 3. When glue needs to be added, the plunger of the plunger pump 5 starts to push downward to push the sealing agent out of the material bottle and apply it on the glass slide to be sealed through the glue dropping probe 3. At the same time, the micrometer balance 4 will measure the weight of the sealing agent and transmit the reading to the control device. The control device will adjust the running speed and stroke of the plunger pump 5 according to the reading of the micrometer balance 4 to ensure glue addition. Precise control of the amount; there will be liquid hanging at the needle outlet of the glue dripping probe 3, which will cause the amount of sealing agent dripped out each time to be inconsistent. After each drop of liquid, the motor controls the plunger pump 5 to suck back, and the liquid beads hanging at the needle are sucked back into the needle to achieve a stable glue output. The excess sealing agent will also be sucked back by the plunger pump 5, thereby ensuring that the glue adding mechanism drips the sealing agent in a consistent amount each time. Through such a glue adding mechanism, accurate glue adding of the sealing agent can be achieved, ensuring the consistency and accuracy of the glue adding amount.

[0034] Combination Figure 4 As shown, after the glue is applied to the glass slide 6, the adsorption mechanism 1 will seal the sucked cover glass 8. When sealing, the first suction cup 121 or the second suction cup 131 is moved downward to drive one side of the cover glass to adhere to the glass slide 6 first, and then the other side suction cup is moved downward, so that the cover glass is bent to remove possible bubbles to achieve a good sealing effect.
