Traditional manual operation methods can no longer meet the requirements of modern laboratories for accuracy, efficiency and cleanliness. Manual packaging is not only time-consuming and laborious, but also difficult to ensure that the amount of each packaging is accurate and consistent, which is unacceptable for scientific research that requires strict control of experimental conditions.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 2 As shown, the embodiment of the present application provides a laboratory glue filling equipment, including a frame 1, a slide 5 slidably connected to the frame 1, and a first driving assembly 7 for driving the slide 5 to slide longitudinally. The first driving assembly 7 is specifically an electric cylinder with a torque sensor, and the electric cylinder is fixed to the top of the frame 1, and the output end of the electric cylinder is fixedly connected to the slide 5. It also includes a glue storage barrel 9 arranged on the frame 1, a pressure plate 10 arranged on the slide 5, and a clamping fixture 8 for clamping a syringe detachably connected to the slide 5. A piston rubber ring is arranged on the outer peripheral wall of the pressure plate 10. The pressure plate 10 is slidably adapted to the glue storage barrel 9, and a closed chamber is formed between the pressure plate 10 and the glue storage barrel 9. The torque sensor can sense the downward pressure of the pressure plate 10 in real time to ensure that the downward pressure process is neither too violent to cause the glue liquid to splash out, nor too gentle to effectively push the glue liquid. The pressure plate 10 is provided with a liquid collection port, and the liquid collection port is connected to the syringe on the clamping fixture 8 through a rubber delivery tube 14. The pressure plate 10 is configured so that when the pressure plate 10 is pressed down, the glue in the closed chamber is dispensed into the syringe from bottom to top.

[0035] It should be noted that the above-mentioned laboratory glue filling and dispensing equipment is not limited to the dispensing of glue, but can also be used for the dispensing of other fluids such as silver paste.

[0036] When the above-mentioned laboratory glue filling and dispensing equipment is working, the clamping fixture 8 is installed on the slide 5, and the first driving component 7 is started to drive the slide 5 and the pressure plate 10 thereon to slide longitudinally toward the glue storage barrel 9. During the sliding process, the pressure plate 10 gradually fits with the opening of the glue storage barrel 9 to form a closed chamber. As the pressure plate 10 is further pressed downward, the air in the closed chamber is discharged, and the glue begins to flow from bottom to top under the action of pressure. The glue enters the glue delivery tube 14 through the liquid intake port and is finally dispensed into the syringe. The glue filling operation is completed.

[0037] In the above method, a closed chamber is formed between the pressure plate 10 and the glue storage barrel 9, and the glue is packaged from bottom to top when the pressure plate 10 is pressed down, which effectively avoids the problem of glue dripping due to gravity in the traditional top-down packaging, thereby significantly improving the packaging accuracy of the glue in the syringe and meeting the high requirements of the laboratory for precise packaging; by arranging the glue storage barrel 9 on the frame 1, the pressure plate 10 and the clamping fixture 8 are arranged on the slide 5, and the overall layout is carried out in the longitudinal direction, the occupancy rate of the horizontal space is effectively reduced, and it has the advantages of compact structure and easy operation. Compared with large-scale industrial glue filling equipment, it is easier to adapt to the laboratory's changeable and small-batch packaging needs. The setting of the detachable clamping fixture 8 makes it easy to replace syringes of different specifications and types, which increases the flexibility and versatility of the equipment.

[0038] In this embodiment, Figure 3 As shown, the laboratory glue filling and dispensing equipment also includes a vacuum device and an electric ball valve 17 . A vacuum orifice is provided on the pressure plate 10 . The vacuum orifice, the electric ball valve 17 and the vacuum device are connected in sequence through a vacuum pipe 16 .

[0039] In the above method, the vacuum device can adjust the vacuum time, intensity and other parameters in real time according to the detection value of the torque sensor to maintain a suitable pressure in the closed chamber, so that the glue liquid can be smoothly dispensed into the syringe. In this process, the bubbles inside the glue liquid can float to the surface and finally be discharged along the vacuum device in the form of gas, thereby minimizing the bubbles in the glue liquid.

[0040] In this embodiment, Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the slide 5 is detachably connected to a glue nozzle 15 below the clamping fixture 8 through a threaded structure, which is convenient for replacing glue nozzles 15 of different specifications or types according to different glue filling requirements, thereby increasing the flexibility and versatility of the device. A plug connector 13 is plugged into the liquid extraction port, and the glue delivery pipe 14 is connected between the glue nozzle 15 and the plug connector 13 to form a complete glue delivery channel. The slide 5 is connected to a slide plate 6 in a longitudinal sliding manner. Two blocks 19 are fixedly connected to the slide plate 6. A slot is formed between the two blocks 19 and the slide plate 6. A positioning pin 20 is fixed to the slide plate 6 in the slot. The clamping fixture 8 is provided with a positioning slot 81 adapted to the positioning pin 20. The clamping fixture 8 is inserted into the slot. The clamping fixture 8 is provided with a locking slot 82. Any of the blocks 19 is provided with a locking pin 21 that can be inserted into the locking slot 82. The locking pin 21 can be connected to the block 19 through a threaded structure. The locking pin 21 can be inserted into the locking slot 82 by rotating the locking pin 21. The slide 5 is provided with a second driving component 18 for driving the slide plate 6 to slide so that the syringe is inserted into the glue nozzle 15. The driving component is specifically a second cylinder hinged between the slide 5 and the slide plate 6. The clamping fixture 8 includes a U-shaped slot 84 and an ear end slot 83 for the ear end of the syringe to be inserted into. An elastic U-shaped rubber pad 85 is arranged in the U-shaped slot 84. It should be noted that the ear end of the syringe specifically refers to the edge portion of the syringe close to the extended position of the piston rod.

[0041] Specifically, the elastic U-shaped rubber pad 85 includes a bottom end 851 and two elastic ends 852, the bottom end 851 is fixedly connected to the clamping jig 8, and the clamping jig 8 is respectively provided with active cavities for the two elastic ends 852 to move, and the clamping jig 8 is respectively provided with sliding cavities on one side of each active cavity, and a wedge block 23 is slidably connected in the sliding cavity, one end of the wedge block 23 extends out of the sliding cavity and abuts against the slide plate 6, and a spring 22 is fixedly connected between the other end of the wedge block 23 and the clamping jig 8, and a wedge-shaped adapter portion adapted to the wedge block 23 is provided on the elastic end 852. When the clamping jig 8 is installed in place on the slide plate 6, the two elastic ends 852 embrace and adhere to the outer wall of the syringe.

[0042] When the above-mentioned clamping fixture 8 is working, the syringe is installed on the clamping fixture 8, so that the ear end of the syringe is inserted into the ear end slot 83, and the cylindrical end of the syringe is inserted into the elastic U-shaped rubber pad 85. The clamping fixture 8 is inserted into the slot and the locking pin 21 is locked. During this process, the wedge block 23 is subjected to the pressure of the slide plate 6, moves inward along the sliding cavity and compresses the spring 22. As the wedge block 23 moves, its inclined surface interacts with the wedge-shaped adapter on the elastic end 852, pushing the elastic end 852 to expand out of the active cavity, forming an embrace and tight fit with the outer wall of the syringe, ensuring that the syringe can be firmly clamped. The second drive assembly 18 drives the slide plate 6 to move downward, so that the syringe is inserted into the glue outlet nozzle 15, so as to achieve the corresponding glue path connection between the glue storage barrel 9 and the syringe.

[0043] The above method realizes the precise clamping, positioning and insertion of the syringe, and can adapt to syringes of different specifications, and has good applicability.

[0044] In this embodiment, Figure 7 As shown, a displacement sensor 12 is arranged on the slide 5 above the clamping fixture 8, a third driving assembly 24 for driving the displacement sensor 12 to slide longitudinally is arranged on the slide 5, and a ejector pin 11 that can abut against the piston rod of the syringe is arranged on the sensor.

[0045] Specifically, the third driving assembly 24 includes a screw rod 241 rotatably connected to the slide 5, a first synchronous wheel 244 fixed on the screw rod 241, a motor 246 fixed on the slide 5, a second synchronous wheel 245 fixed on the output end of the motor 246, and a synchronous belt transmission-connected between the first synchronous wheel 244 and the second synchronous wheel 245. The screw rod 241 is a μ-level high-precision screw rod 241. A bracket 243 is slidably connected to the slide 5 through a slide rail pair 242. The displacement sensor 12 is fixed on the bracket 243. The bracket 243 is provided with a thread groove threadedly connected to the screw rod 241.

[0046] In the above manner, the displacement accuracy of the ejector pin 11 can be effectively improved by setting the μ-level high-precision screw rod 241. During operation, the ejector pin 11 first presses the piston rod of the syringe into place, and then moves up to the approximate position of the piston rod after the glue is filled. The piston rod will rise under the pressure of the glue and lift the ejector pin 11 a small distance to trigger the displacement sensor 12 to work, thereby sending a corresponding signal for subsequent blocking of the glue.

[0047] In this embodiment, Figure 8As shown, the glue delivery pipe 14 is a hose, a cushion block 25 is fixed on the slide 5, and a first cylinder 26 is provided on the slide 5 for pressing the glue delivery pipe 14 against the cushion block 25 to block the glue liquid. Through the actuation of the first cylinder 26, the glue delivery pipe 14 can be quickly and accurately pressed against the cushion block 25, thereby effectively blocking the flow of the glue liquid. When it is necessary to continue the glue filling, the first cylinder 26 moves in the opposite direction to release the pressure on the glue delivery pipe 14, and the glue liquid can quickly resume flowing. This instant blocking and recovery function improves the controllability and flexibility of the glue filling process.

[0048] In this embodiment, Figure 1 As shown, the laboratory glue filling equipment also includes a PLC controller, an electronic scale 4, a machine table 3 and a machine cover 2 fixed on the machine table 3. The frame 1 is fixed on the machine table 3 located in the machine cover 2. The electronic scale 4 is placed on the machine table 3 located on one side of the frame 1. The electronic scale 4, the first drive component 7, the second drive component 18, the third drive component 24, the displacement sensor 12, the vacuum device, and the first cylinder 26 are electrically connected to the PLC controller respectively. The electronic scale 4 is used to weigh the syringe filled with glue and send the weighing data to the PLC controller in real time.

[0049] In the above method, the electronic scale 4 communicates with the PLC controller, and the weighing data can be sent to the PLC controller in real time, so that the PLC controller can monitor the changes in the amount of glue in the filling process in real time, and make timely feedback and adjustments as needed, which is conducive to timely discovering and correcting deviations in the filling process, ensuring the stability and consistency of the filling process, and improving the accuracy and reliability of the filling. After multiple corrections, it is tested that the filling error of the glue in the syringe of the laboratory filling and glue filling equipment of the present application can be controlled within 0.02 grams. In the early stage, each filled syringe needs to be placed on the electronic scale 4 for weighing. After multiple weighings, when the filling weight of each syringe can be maintained within the error range, the weighing link can be cancelled. Among them, the algorithm of the correction process adopts the existing technology and is not repeated in this embodiment.

[0050] In this embodiment, Fig. 9 As shown, two half-barrel covering blocks 27 and a pressing block 28 for fixing the half-barrel covering block 27 on the frame 1 are provided at the bottom of the frame 1, and the pressing block 28 is detachably connected to the frame 1 by bolts, and the glue storage barrel 9 is covered and fixed between the two half-barrel covering blocks 27. The glue storage barrel 9 is fixed at the bottom of the frame 1 by combining the two half-barrel covering blocks 27 and the pressing block 28, thereby achieving stable covering and convenient disassembly and assembly of the glue storage barrel 9.

[0051] In this embodiment, the number of the clamping fixtures 8 can be one, two or more, so as to realize multi-station glue filling operations.

[0052] The present application also discloses a method for dispensing and filling glue, comprising any of the laboratory dispensing and filling glue equipment, and further comprising the following steps:

[0053] S1. The syringe is mounted on the clamping fixture 8. The third driving assembly 24 first drives the ejector pin 11 to press the piston rod of the syringe down to the position, and then drives the ejector pin 11 upward to a waiting position. This position should ensure that the ejector pin 11 does not interfere with the subsequent dispensing process of the glue solution.

[0054] S2, the first driving assembly 7 drives the pressure plate 10 to press down a certain distance, and the vacuum device evacuates the closed chamber and maintains the pressure for a period of time, so that the bubbles in the glue liquid float to the surface and are discharged through the vacuum device as much as possible, and the pressure plate 10 continues to press down. When the pressure plate 10 contacts the liquid surface in the glue storage barrel 9, the glue liquid is dispensed into the syringe from bottom to top under the pressure generated by the pressure plate 10;

[0055] S3, when the glue pushes the piston rod upward to the waiting position, it continues to push the ejector pin 11 upward to the target setting value of the displacement sensor 12, the first cylinder 26 is ejected, the glue is blocked, and the dispensing of the glue in the syringe is completed.

[0056] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
