Description

Technical Field

[0001] This application relates to the technical field of adhesive coating, and particularly relates to a glue coating device and a glue coating operation system.

Background Art

[0002] In the glue coating process of inner hole workpieces, a spin coater is a key device to achieve efficient glue coating. It uses the centrifugal force during high-speed rotation to throw out the glue liquid and sputter it onto the inner hole wall to form a coating layer.

[0003] In existing related glue coating devices, the storage container and the power glue coating component are usually designed separately. The glue liquid is transported from the storage container to the glue outlet through a hose. The output end of the glue outlet is correspondingly arranged with the power glue coating component. The glue liquid drips onto the surface of the power glue coating component, and the high-speed rotating power glue coating component throws out the glue liquid on the surface. However, there are certain limitations in the design and function of existing related glue coating devices.

[0004] Firstly, the process integration degree of related devices is not high. After the glue liquid quantitatively dripped from the glue outlet is thrown out by the power glue coating component, the morphology of the thrown-out fine liquid droplets is often difficult to control, resulting in uneven thickness of the final coating layer and poor coating quality.

[0005] Secondly, the separate design of the storage container and the power glue coating component makes the overall structure of the device complex, with a large number of components and a large number of component connection relationships, resulting in a high failure rate of the device and a high maintenance cost.

[0006] Therefore, how to optimize the design of the glue coating device, improve the coating quality while reducing the machine maintenance cost, is an urgent problem to be solved by those skilled in the art.

[0034] The glue - applying device 20 includes a material storage member 21, a flow - guiding member 22, a glue - applying member 23, a first connecting member 24, a second connecting member 25, a driving device 26, and a mounting frame 27.

The receiving space 211, the first cavity 221, and the second cavity 231 are interconnected to form a flow path for the glue. One end of the glue - applying member 23 away from the flow - guiding member 22 is provided with a glue outlet 233. The driving device 26 drives the glue - applying member 23 to rotate, and the rotation axis 235 of the glue - applying member 23 intersects with the center line of the glue outlet 233. Based on the centrifugal principle, the glue is thrown out of the glue outlet 233 by the high - speed rotating glue - applying member 23 onto the hole wall of the workpiece, forming a glue coating layer on the hole wall of the workpiece. One end of the mounting frame 27 is fixedly connected to the first connecting member 24 and the driving device 26, and the opposite end is fixedly installed on a moving platform or a machining center.

[0035] Specifically, the material storage member 21 has a funnel - like structure with an opposite feed end 213 and a discharge end 215. The glue is fed into the opening of the feed end 213, flows naturally along the inner wall of the receiving space 211 to the discharge end 215, and then flows out from the opening of the discharge end 215.

[0036] The first connecting member 24 is provided with a third cavity 241. One end of the third cavity 241 communicates with the discharge end 215 of the material storage member 21, and the opposite end communicates with the first cavity 221 of the flow - guiding member 22. In this embodiment, the discharge end 215 of the material storage member 21 is provided with an internal thread, and the first connecting member 24 is correspondingly provided with an external thread so that the material storage member 21 is thread - connected to the first connecting member 24. In other embodiments, the connecting member can also be provided with a threaded through - hole, and the discharge end 215 of the material storage member 21 can be provided with an external thread so that the material storage member 21 is thread - connected to the first connecting member 24.

[0037] In order to reduce the frequency of downtime for adding materials, the volume of the material storage member 21 is usually large, which means that the volume of the material storage member 21 is relatively large compared to other components. The setting of the first connecting member 24 enables the convenient assembly or disassembly of the material storage member 21, saving the packaging, transportation cost, and maintenance cost of the whole machine.

[0038] The flow guide member 22 has opposite first and second ends 223 and 224. The first cavity 221 penetrates from the first end 223 to the second end 224. The first end 223 is fixedly connected to the storage member 21 through the first connecting member 24, and the second end 224 is fixed to the driving device 26 through the second connecting member 25.

[0039] The driving device 26 includes a stator group 261, a rotor group 263, a bearing 265 and a controller 267. The stator group 261 is sleeved on the flow guide member 22 through the bearing 265. The flow guide member 22 is fixedly connected to the rotor group 263. The controller 267 is electrically connected to the stator group 261. The stator group 261 includes a stator base 2611 and a winding iron core 2613 sleeved and fixed on the stator base 2611. The stator base 2611 is provided with a receiving cavity, and the bearing 265 is abutted against the inner wall of the receiving cavity. The stator base 2611 is fixed to one side of the mounting frame 27 by bolts, and the first connecting member 24 is fixed to the other side of the mounting frame 27 by bolts.

[0040] The rotor group 263 includes a rotor cover 2631 and a steel ring 2633. The steel ring 2633 is sleeved and fixed on the outer wall of the rotor cover 2631. One end of the flow guide member 22 is fixedly connected to the rotor cover 2631. A plurality of magnets (not shown in the figure) are fixedly arranged in a circular array on the inner wall of the rotor cover 2631. The controller 267 controls the current direction and magnitude of the winding iron core 2613 so that the stator group 261 generates a rotating magnetic field, and the magnets of the rotor group 263 have a stable magnetic field. The rotating magnetic field interacts with the stable magnetic field of the magnets to form an electromagnetic torque to drive the rotor group 263 to rotate relative to the stator group 261, and the flow guide member 22 rotates synchronously and coaxially with the rotor group 263.

[0041] The first connecting member 24 is further provided with a fixing groove 243, and the fixing groove 243 is arranged at one end of the first connecting member 24 close to the flow guide member 22. The glue application device 2 further includes a seal 28, and the seal 28 is sleeved on the flow guide member 22 and is arranged adjacent to the bearing 265. The outer wall of the seal 28 is abutted against the inner wall of the fixing groove 243 to prevent the glue from overflowing when flowing from the third cavity 241 to the first cavity 221, and the glue leaks to the bearing 265 and affects the service life of the driving device 26.

[0042] The glue application device 2 further includes a washer 29, and the washer 29 is clamped between the seal 28 and the bearing 265 to prevent interference between the seal 28 and the bearing 265 and affect the service life of the driving device 26.

[0043] The second connecting member 25 is provided with a fourth cavity 251. One end of the fourth cavity 251 communicates with the second cavity 231, and the opposite end is provided with internal threads. One end of the glue application member 23 away from the glue outlet 233 is provided with external threads. The glue application member 23 and the second connecting member 25 are threadedly connected so that the flow guiding member 22 and the glue application member 23 are fixedly connected into an integral structure. The second connecting member 25 is fixed to the rotor cover 2631 by bolts, and the rotor group 263 drives the flow guiding member 22, the second connecting member 25 and the glue application member 23 to rotate synchronously and coaxially.

[0044] The advantage of setting the second connecting member 25 is that the specification of the glue application member 23 can be conveniently replaced according to actual processing requirements, and at the same time, the maintenance cost of the whole machine is reduced.

[0045] The glue application device 2 further includes an adjusting member 20. The adjusting member 20 is threadedly connected to one end of the glue application member 23 and is correspondingly arranged with the glue outlet 233. The position of the adjusting member 20 relative to the glue outlet 233 is adjusted by threading to adjust the glue output of the glue. Specifically, the inner wall of the second cavity 231 is provided with internal threads, and the adjusting member 20 is correspondingly provided with external threads, and the position of the adjusting member 20 relative to the glue outlet 233 is adjusted by threading.

[0046] Please refer to Figure 5 and Figure 6 , Figure 5 For Figure 2 a perspective three-dimensional structure schematic diagram of one perspective of the adjusting member shown, Figure 6 For Figure 2 a perspective three-dimensional structure schematic diagram of another perspective of the adjusting member shown. One end of the adjusting member 20 is provided with a flow dividing cavity 201, and the outer surface of the opposite end is provided with a flow limiting groove 203. The flow limiting groove 203 is oppositely arranged with the glue outlet 233. The flow dividing cavity 201 communicates with the second cavity 231 through an open end and communicates with the flow limiting groove 203 through a drainage hole 205. The flow dividing cavity 201 and the flow limiting groove 203 cooperate to adjust the flow rate of the glue to avoid glue overflow.

[0047] It should be noted that the drainage holes 205 are symmetrically distributed around the rotation axis 235 of the glue application member 23, and all the drainage holes 205 have exactly the same specifications to balance the centrifugal torque under high-speed rotation. In this embodiment, the number of the drainage holes 205 is three. In other embodiments, the number of the drainage holes 205 can be increased or decreased according to actual operation requirements.

[0048] The adjusting member 20 is provided with a disassembly hole 207, and the disassembly hole 207 and the shunt cavity 201 are oppositely arranged at both ends of the adjusting member 20. By using a disassembly tool to hold or clamp the disassembly hole 207, etc., the thread adjustment between the glue applying member 23 and the glue applying member 23 can be conveniently carried out, without the need to energize or magnetize to control the flow rate of the glue.

[0049] When the glue applying operation is not carried out, the position of the adjusting member 20 relative to the glue outlet 233 is adjusted by threads, so that the current limiting groove 203 and the glue outlet 233 do not correspond to each other. The glue stays in the current limiting groove 203 and cannot flow to the glue outlet 233.

[0050] When the glue applying operation is carried out, the position of the adjusting member 20 relative to the glue outlet 233 is adjusted by threads, so that the current limiting groove 203 and the glue outlet 233 partially correspond to each other. Under the action of centrifugal force, the glue flows from the current limiting groove to the glue outlet 233 and is thrown out to the inner hole wall of the workpiece to form a coating layer.

[0051] In summary, the glue applying device provided by the present application organically combines the storage container and the power glue applying component, improves the process integration degree, is easier to control the morphology of the ejected fine droplets, and makes the coating layer of the workpiece thinner and more uniform; at the same time, it expands the types of glue, and can also coat efficiently and uniformly with a single-component high-temperature glue with low fluidity; the overall structure of the device is simple, the structural reliability is higher, and the machine maintenance cost is lower.

[0052] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
