Therefore,

[0004] Developing a dispensing device that can achieve efficient and precise dispensing and improve the airtightness of products is urgently needed.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0027] According to an embodiment of the present invention, a precision dispensing device for sealing electronic products is provided.

[0028] like Figures 1-3As shown, a precision dispensing device for sealing electronic products includes: a body 1, a workpiece stage 2 inside the body 1, a first column 3 and a second column 4 respectively on the top two sides of the workpiece stage 2, a first transmission mechanism 5 for horizontal adjustment at the top of the first column 3, a guide rail 6 at the top of the second column 4, a slider 7 movably sleeved on the guide rail 6, a loading plate 8 connected between the slider 7 and the first transmission mechanism 5, a second transmission mechanism 9 for horizontal adjustment on one side of the loading plate 8, a telescopic cylinder 10 connected to the second transmission mechanism 9, a bearing plate 11 fixedly connected to the output end of the telescopic cylinder 10, a metering pump 12 and a dispensing head 13 on the bearing plate 11, and a glue storage box 14 on one side of the workpiece stage 2, the metering pump 12 being connected to the glue storage box 14 and the dispensing head 13 respectively through a conduit.

[0029] The first transmission mechanism 5 includes: a first protective frame 51 fixedly installed at the top of the first column 3; a first threaded rod 52 horizontally installed inside the first protective frame 51; a first threaded block 53 movably sleeved on the first threaded rod 52; the top of the first threaded block 53 fixedly connected to the loading plate 8; and a first drive motor 54 connected to the end of the first threaded block 53; and the first drive motor 54 fixedly installed on one side of the first protective frame 51.

[0030] In this technical solution, when the first drive motor 54 starts, it drives the first threaded rod 52 to rotate, causing the first threaded block 53 to move horizontally on the first threaded rod 52, thereby realizing the horizontal position adjustment of the loading plate 8.

[0031] The second transmission mechanism 9 includes: a second protective frame 91 fixedly disposed on one side of the loading plate 8; a second threaded rod 92 horizontally disposed inside the second protective frame 91; a second threaded block 93 movably sleeved on the second threaded rod 92; one side of the second threaded block 93 fixedly connected to the telescopic cylinder 10; and a second drive motor 94 connected to the end of the second threaded rod 92; the second drive motor 94 fixedly mounted on one side of the second protective frame 91.

[0032] In this technical solution, when the second drive motor 94 is working, it drives the second threaded rod 92 to rotate, which in turn drives the second threaded block 93 to move horizontally on the second threaded rod 92, thereby adjusting the horizontal position of the telescopic cylinder 10, the bearing plate 11, the metering pump 12 and the dispensing head 13.

[0033] In addition, a pressure sensor 15 is also installed inside the dispensing head 13. The machine body 1 is also equipped with a controller, which is electrically connected to the telescopic cylinder 10, the first drive motor 54, the second drive motor 94, the pressure sensor 15 and the metering pump 12 via wires.

[0034] Specifically, the dispensing head 13 is also equipped with a pressure sensor 15 to monitor the pressure of the adhesive during dispensing in real time, so as to accurately control the amount of adhesive. At the same time, the controller can control the various components to work together according to the preset program or the operator's instructions to achieve precise dispensing.

[0035] In addition, a clamp 16 is provided at the top of the workpiece table 2, which is adapted to the dispensing head 13. An operation window 17 is provided on the side of the machine body 1 that is adapted to the clamp 16.

[0036] In this technical solution, the clamp 16 is adapted to the dispensing head 13 to fix the electronic product and ensure the product's stable position during the dispensing process. An operation window 17 is provided on one side of the machine body 1 that adapts to the clamp 16, facilitating the placement and removal of the electronic product by the operator, as well as observation of the dispensing process.

[0037] Using the above technical solution, specifically, during implementation, the electronic product to be glued is placed on the fixture 16 of the workpiece stage 2 to ensure the product is firmly fixed. An appropriate amount of glue is added to the glue storage box 14. Various glue dispensing parameters, such as dispensing position, glue volume, and dispensing speed, are set via the controller. The first drive motor 54 is started. According to the preset dispensing position, the first drive motor 54 drives the first threaded rod 52 to rotate, causing the first threaded block 53 to move, thereby adjusting the horizontal position of the loading plate 8 and moving the dispensing head 13 to approximately above the dispensing area of ​​the product. Next, the second drive motor 94 is started. The second drive motor 94 drives the second threaded rod 92 to rotate, causing the second threaded block 93 to move, further precisely adjusting the horizontal position of the dispensing head 13 so that it is aligned with the sealing gap of the product. The telescopic cylinder 10 is activated, causing the dispensing head 13 to descend to the appropriate dispensing height. The controller controls the metering pump 12 to operate, delivering the glue in the glue storage box 14 to the dispensing head 13 through a conduit, and the dispensing head 13 begins dispensing. During the dispensing process, pressure sensor 15 monitors the adhesive pressure in real time and transmits the data to the controller. The controller adjusts the operating status of metering pump 12 based on the pressure data to ensure stable adhesive dispensing. After dispensing is complete, telescopic cylinder 10 lifts dispensing head 13, removing it from the product surface. The operator then removes the dispensed product through operating window 17 for further processing.

[0038] In summary, by means of the above-mentioned technical solution of this utility model, the following effects can be achieved: through the first transmission mechanism 5 and the second transmission mechanism 9, the position of the dispensing head 13 can be precisely adjusted in two horizontal directions, and in conjunction with the telescopic cylinder 10, the dispensing head 13 can be accurately positioned in three-dimensional space, so as to accurately apply glue to the sealing gaps of electronic products, thus solving the problem that traditional dispensing is difficult to accurately seal gaps.

[0039] Meanwhile, the metering pump 12 can accurately control the amount of glue delivered from the glue storage box 14 to the dispensing head 13. The pressure sensor 15 inside the dispensing head 13 monitors the glue pressure in real time and feeds it back to the controller. The controller adjusts the working state of the metering pump 12 according to the pressure data, further ensuring accurate control of the glue amount, improving the sealing effect and airtightness of the product, and increasing the efficiency of the dispensing work.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
