Description

Technical Field

[0001] This utility model relates to the technical field of screw dispensing devices, specifically a screw dispensing device. Background Technology

[0002] Dispensing equipment, also known as dispensing machine, coating machine, dripping machine, glue applicator, or potting machine, is an automated machine specifically designed to control fluids and apply them to the surface or interior of a product. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, and prevent stringing, leakage, and dripping. Dispensing equipment is mainly used for the precise application of adhesives, paints, and other liquids to precise locations on each product during product manufacturing. It can be used to apply dots, lines, circles, or arcs. Currently, there are many applications such as solder paste dispensing in the electronics assembly and semiconductor packaging industries. Traditional screw-type dispensing equipment is often made of metal. Due to limitations in processing precision, there is often a gap between the screw and its mating screw sleeve. Solder paste and other substances contain a large number of fine metal particles. When these metal particles enter the gap, they can easily stick together, causing subsequent dispensing instability.

[0003] A search revealed existing technology (application number: CN202211034899.X), which describes "a screw-type dispensing device". This utility model includes a rubber tube and a screw mechanism, one end of which extends into the cavity of the rubber tube, and the external thread of the screw mechanism is interference-fitted with the inner surface of the rubber tube.

[0004] However, while existing technologies do not cause changes in the size of the rubber tube due to corrosion from cleaning solvents or adhesives during disassembly, cleaning, or operation, thus ensuring the working stability of the rubber tube within its normal lifespan, they still have some shortcomings: replacing the needle is inconvenient, and cleaning is not easy.

[0031] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-7 This utility model provides a screw dispensing device, including: a platform 4, a support column 5 fixedly mounted on the platform 4, a fixing rod 6 fixedly mounted on one side of the top of the support column 5, a dispensing assembly 2 mounted on the fixing rod 6, the dispensing assembly 2 including a dispensing cavity 210, the dispensing cavity 210 being connected to the end of the fixing rod 6 away from the support column 5, a motor 21 being mounted inside the dispensing cavity 210, a rotating rod 22 being fixedly connected to the output end of the motor 21, the rotating rod 22 passing through and rotatably connected to the top of the dispensing tank 23, and a threaded rod 24 being fixedly connected to the bottom of the rotating rod 22, the threaded rod 24 being disposed inside the dispensing tank 23, and the threaded rod 24 being threadedly rotatably connected to the dispensing tank 23, a needle fixing block 25 being disposed below the dispensing tank 23, a needle 26 being disposed below the needle fixing block 25, and the needle 26 being disposed below the dispensing cavity 210.

[0033] In this embodiment, the glue infeed assembly, the glue pushing assembly, and the fixing assembly constitute the screw dispensing device involved in this application, realizing a screw dispensing device. Any glue that needs to be dispensed can be used with this device, and this application does not limit the specific type of glue.

[0034] In this embodiment, the motor 21 is started, which drives the rotating rod 22 to rotate, and the rotating rod 22 drives the threaded rod 24 to rotate.

[0035] In this embodiment, the threaded rod 24 rotates within the glue dispensing tank 23, pushing the glue downwards and extruding it through the needle 26.

[0036] It should be noted that the needle is made of PTFE material. PTFE has extremely high chemical inertness and can resist the corrosion of almost all strong acids, strong alkalis, organic solvents and oxidants, making it suitable for various chemical environments. In addition, PTFE material has an extremely low coefficient of friction and good lubricity, and its surface does not easily adhere to substances. This characteristic can reduce glue residue and clogging during the dispensing process, ensuring smooth and accurate dispensing.

[0037] Specifically, the dispensing cavity 210 is provided with a glue inlet assembly 1, and a pump 14 is provided above the dispensing cavity 210. One end of the pump 14 is connected to a glue dispensing tube 15, and a glue storage chamber 13 is provided in the middle of the glue dispensing tube 15. The glue dispensing tube 15 is connected to the inside of the glue storage chamber 13. The end of the glue dispensing tube 15 away from the glue storage chamber 13 is connected to the inner wall of the dispensing cavity 210. The glue dispensing tube 15 is connected to the inside of the glue dispensing tank 23 through a glue inlet 16 provided on the glue dispensing tank 23.

[0038] In this embodiment, the pump 14 is started, pumping the glue into the glue storage chamber 13 through the glue dispensing pipe 15, and then into the glue dispensing tank 23 through the glue inlet 16 via the glue dispensing pipe 15, replenishing the glue dispensing tank 23 and ensuring that the glue dispensing work continues.

[0039] Specifically, a valve 12 is provided on the outside of the glue storage cavity 13, and a glue pouring port 11 is provided above the valve 12.

[0040] In a preferred embodiment, opening valve 12 allows glue to be poured into glue storage chamber 13 through glue inlet 11; closing valve 12 controls the flow of glue, facilitating glue replenishment and flow control.

[0041] Specifically, a fixing component 3 is provided on the needle fixing block 25. The fixing component 3 includes a knob 301. A threaded rod 302 is fixedly connected to the inner side of the knob 301. A rotating block 303 is fixedly connected to the end of the threaded rod 302 away from the knob 301.

[0042] It should be noted that rotating knob 301 causes threaded rod 302 to rotate, and threaded rod 302 causes rotating block 303 to move.

[0043] Specifically, threaded rod 302 passes through and is threadedly connected to adhesive cavity 210, rotating block 303 passes through and is rotatably connected to push block 304, and push block 304 slides to connect to sliding groove 29 provided in adhesive cavity 210 through sliding block 305 fixed on both sides below.

[0044] In a preferred embodiment, the threaded rod 302 rotates, causing the rotating block 303 to move, and the rotating block 303 causes the pushing block 304 to slide in the sliding groove 29 through the sliding block 305.

[0045] Specifically, there are connecting rods 306 symmetrically rotatably connected on both sides above the push block 304, and clamping blocks 307 are rotatably connected below the connecting rods 306. The clamping blocks 307 are slidably connected to the sliding grooves 28 provided in the glue cavity 210 through the sliding grooves 308 provided at both ends of the bottom.

[0046] It should be noted that the movement of the push block 304 causes the connecting rod 306 to rotate, and the connecting rod 306 causes the clamping block 307 to slide in the sliding groove 28 through the sliding groove 308, thereby controlling the clamping or loosening action and facilitating the replacement of the needle.

[0047] Specifically, the clamping block 307 engages with the fixing groove 27 on the outer ring of the needle fixing block 25 via the fixing block 309 set on the inner side.

[0048] In this embodiment, the clamping block 307 moves, causing the fixing block 309 to engage or disengage from the fixing groove 27, thereby controlling the fixing or loosening of the needle fixing block 25.

[0049] When using this product, if glue dispensing is required, the user places the item to be dispensed on platform 4, opens valve 12, and pours glue into the dispensing port 11. The glue is stored in the storage chamber 13. After the glue is poured in, valve 12 is closed, and pump 14 is started. The glue flows from dispensing pipe 15 into dispensing tank 23. Motor 21 is started, and rotating rod 22 drives threaded rod 24 to rotate. The glue flows downwards under the rotation of threaded rod 24, enters needle fixing block 25, and finally flows out from needle 26, thus dispensing. After dispensing is complete, needle 26 needs to be replaced. At 26 o'clock, the user rotates knob 301, threaded rod 302 rotates and moves forward in dispensing cavity 210, rotating block 303 is pushed forward in push block 304, sliding block 305 under push block 304 slides forward on sliding groove 29, connecting rod 306 on push block 304 moves to both sides, clamping block 307 moves to both sides under the action of connecting rod 306, thereby releasing clamping block 307 from locking needle fixing block 25, at which point the user can remove needle 26 and replace it.

[0050] This utility model discloses a screw dispensing device. The user places the item on the platform and completes the pouring and delivery of glue by simply operating the valve and starting the pump. The dispensing process is simple, quick, and easy to learn. The locking of the needle fixing block can be easily released by rotating the knob, which facilitates the replacement of the needle and improves work efficiency. The pump and glue delivery tube accurately deliver the glue into the glue delivery tank, and the rotation of the rotating rod and the screw rod makes the glue flow smoothly to the needle, ensuring the stability of the dispensing.

[0051] Finally, it should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power.
