Description

[Technical Field]

[0001] This application relates to the field of adhesive coating technology, and more particularly to an adhesive coating equipment and adhesive coating operation system. [Background Technology]

[0002] In the coating process of internal workpieces, the glue-spraying machine is a key piece of equipment for achieving efficient coating. It uses the centrifugal force of high-speed rotation to throw the glue liquid out and splash it onto the inner wall of the hole to form a coating layer.

[0003] In existing adhesive coating equipment, the storage container and the powered adhesive coating component are typically designed separately. The adhesive is delivered from the storage container to the dispensing nozzle via a flexible hose. The output end of the dispensing nozzle is correspondingly positioned to the powered adhesive coating component, where the adhesive drips from the nozzle onto the surface of the component. The high-speed rotating component then flings the adhesive off the surface. However, existing adhesive coating equipment has certain limitations in design and function.

[0004] Firstly, the integration of related equipment is not high. The glue liquid dispensed quantitatively from the dispensing nozzle is often difficult to control in terms of the shape of the tiny droplets after being ejected by the power coating component, resulting in uneven coating thickness and poor coating quality.

[0005] Secondly, the separate design of the storage container and the power coating component makes the overall structure of the equipment complex, with a large number of parts and connections, resulting in a higher failure rate and higher maintenance costs.

[0006] Therefore, how to optimize the design of coating equipment, improve coating quality, and reduce machine maintenance costs is a problem that urgently needs to be solved by those skilled in the art. [Utility Model Content]

[0007] This application provides a coating equipment and coating operation system that organically combines a material storage container with a power coating component, simplifying the overall structure, improving coating quality, and reducing machine maintenance costs.

[0008] This application provides an adhesive coating device, including a storage component with a receiving space for storing adhesive liquid; a flow guide with a first cavity communicating with the receiving space; an adhesive coating component with a second cavity communicating with the first cavity, and an adhesive outlet at one end of the adhesive coating component away from the flow guide; a first connector for detachably connecting the storage component and the flow guide into a single structure; a second connector for detachably connecting the flow guide and the adhesive coating component into a single structure; and a driving device for driving the adhesive coating component to rotate, wherein the rotation axis of the adhesive coating component intersects with the center line of the adhesive outlet; the receiving space, the first cavity, and the second cavity cooperate to form a flow path for the adhesive liquid, and the adhesive liquid is thrown out through the adhesive outlet onto the hole wall of the workpiece to form a coating layer.

[0009] In some embodiments, the drive device includes a stator assembly, a rotor assembly, bearings, and a controller. The stator assembly is sleeved on the guide member through the bearings. The guide member is fixedly connected to the rotor assembly. The controller is electrically connected to the stator assembly.

[0010] In some embodiments, a seal is also included, which is fitted onto the flow guide and disposed adjacent to the bearing to prevent adhesive leakage into the bearing.

[0011] In some embodiments, an adjusting member is also included. The adjusting member is threadedly connected to one end of the adhesive applicator and is disposed corresponding to the adhesive outlet. The position of the adjusting member relative to the adhesive outlet is adjusted by adjusting the thread to adjust the amount of adhesive dispensed.

[0012] In some embodiments, one end of the adjusting member is provided with a flow-diverting cavity, and the outer surface of the opposite end is provided with a flow-limiting groove. The flow-diverting cavity is connected to the second cavity through an opening and to the flow-limiting groove through a drainage hole. The flow-diverting cavity and the flow-limiting groove cooperate to adjust the flow rate of the adhesive to avoid overflow.

[0013] In some embodiments, the adjusting member is provided with disassembly holes, which are located at both ends of the adjusting member opposite to the diversion cavity.

[0014] In some embodiments, a gasket is also included, which is sandwiched between the seal and the bearing to prevent interference between the seal and the bearing.

[0015] In some embodiments, a mounting bracket is also included, one end of which is fixedly connected to the first connector and the stator assembly.

[0016] This application also provides a glue application system, including: a motion platform, comprising a first motion component, a second motion component, and a third motion component arranged perpendicularly to each other; a CNC device, controlling the first motion component to reciprocate along a first direction, controlling the second motion component to reciprocate along a second direction, and controlling the third motion component to reciprocate along a third direction, wherein the first direction, the second direction, and the third direction are mutually perpendicular; and a glue application device as described above, installed on the motion platform, wherein the first motion component, the second motion component, and the third motion component cooperate to drive the glue application device to perform glue application on the workpiece.

[0017] This application also provides an adhesive application system, including: a workpiece conveying device, comprising multiple workstations arranged sequentially along the same direction; a CNC device for controlling the travel direction and travel speed of the workpiece conveying device; and an adhesive application device as described above, fixedly suspended above the workpiece conveying device, for applying adhesive to the workpieces at the workstations.

[0018] Compared with the coating equipment in related technologies, the coating equipment provided in this application organically combines the storage container with the power coating component, which improves the process integration and makes it easier to control the morphology of the small droplets thrown out, resulting in a thinner and more uniform coating layer on the workpiece. At the same time, it expands the types of adhesives, and can achieve efficient and uniform coating effect even when using high-temperature adhesives with lower fluidity. The overall structure of the equipment is simple, the structural reliability is higher, and the machine maintenance cost is lower. [Attached Image Description]

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the adhesive application system provided in one embodiment of this application. The adhesive application system 1 is applied to the adhesive coating process of a workpiece. Specifically, the adhesive application system 1 can be used for the adhesive coating process of the inner hole of the workpiece. For example, applying adhesive to the inner wall of a motor housing.

[0030] The motion platform 11 also includes an operating table 117. One end of the operating table 117 is equipped with a gantry frame 1171, one side of which is a processing side. This processing side is used for pre-processing workpieces, machining workpieces, or inspecting workpiece tolerances. The first motion component 111 is fixedly installed on the top surface of the operating table 117. The first motion component 111 has a workstation 119 for fixing the workpiece to be processed. The second motion component 113 is fixedly installed on the processing side of the gantry frame 1171 and is perpendicular to the first motion component 111. The third motion component 115 is fixedly installed on the side of the second motion component 113 facing the workstation 119 and is perpendicular to both the first motion component 111 and the second motion component 113.

[0033] Please refer to the following: Figures 2 to 4 ,in Figure 2 This is a three-dimensional structural diagram of the adhesive coating equipment provided in one embodiment of this application. Figure 3 for Figure 2 The diagram shown is an exploded three-dimensional view of the adhesive coating equipment. Figure 4 for Figure 2 The diagram shows a cross-sectional view of the adhesive coating equipment.

[0034] The adhesive application equipment 20 includes a storage component 21, a flow guide 22, an adhesive application component 23, a first connector 24, a second connector 25, a drive device 26, and a mounting frame 27. The first connector 24 detachably connects the storage component 21 and the flow guide 22 into a single structure, and the second connector 25 detachably connects the flow guide 22 and the adhesive application component 23 into a single structure. The storage component 21 has a receiving space 211 for storing adhesive liquid. The flow guide 22 has a first cavity 221, and the adhesive application component 23 has a second cavity 231. The receiving space 211, the first cavity 221, and the second cavity 231 are interconnected to form a flow path for the adhesive liquid. The coating component 23 has a glue outlet 233 at one end away from the guide component 22. The driving device 26 drives the coating component 23 to rotate, and the rotation axis 235 of the coating component 23 intersects the center line of the glue outlet 233. Based on the centrifugal principle, the glue liquid is thrown out through the glue outlet 233 by the high-speed rotating coating component 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 bracket 27 is fixedly connected to the first connecting component 24 and the driving device 26, and the other end is fixedly mounted on the motion platform or machining center.

[0035] Specifically, the storage component 21 has a funnel-shaped structure with a corresponding inlet end 213 and outlet end 215. The adhesive is fed in from the opening of the inlet end 213, flows naturally down the inner wall of the receiving space 211 to the outlet end 215, and then flows out from the opening of the outlet end 215.

[0036] The first connector 24 has a third cavity 241, one end of which communicates with the discharge end 215 of the storage component 21, and the other end communicates with the first cavity 221 of the guide component 22. In this embodiment, the discharge end 215 of the storage component 21 has an internal thread, and the first connector 24 has a corresponding external thread, so that the storage component 21 is threadedly connected to the first connector 24. In other embodiments, the connector may also have a threaded through hole, and the discharge end 215 of the storage component 21 may have an external thread, so that the storage component 21 is threadedly connected to the first connector 24.

[0037] To reduce the frequency of downtime for material replenishment, the storage component 21 is usually large in volume, which means that the volume of the storage component 21 is larger than that of other components. The first connector 24 is provided to facilitate the assembly or disassembly of the storage component 21, saving the packaging, transportation and maintenance costs of the whole machine.

[0038] The flow guide 22 has a first end 223 and a second end 224 opposite to each other. The first cavity 221 extends from the first end 223 to the second end 224. The first end 223 is fixedly connected to the storage device 21 through the first connector 24, and the second end 224 is fixed to the drive device 26 through the second connector 25.

[0039] The drive device 26 includes a stator assembly 261, a rotor assembly 263, a bearing 265, and a controller 267. The stator assembly 261 is sleeved on the guide member 22 via the bearing 265. The guide member 22 is fixedly connected to the rotor assembly 263. The controller 267 is electrically connected to the stator assembly 261. The stator assembly 261 includes a stator base 2611 and a winding core 2613 sleeved and fixed to the stator base 2611. The stator base 2611 has a receiving cavity, and the bearing 265 abuts against the inner wall of the receiving cavity. The stator base 2611 is fixed to one side of the mounting bracket 27 by bolts, and the first connecting member 24 is fixed to the other side of the mounting bracket 27 by bolts.

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

[0041] The first connector 24 is further provided with a fixing groove 243, which is located at one end of the first connector 24 near the guide member 22. The adhesive application device 2 also includes a sealing member 28, which is sleeved on the guide member 22 and disposed adjacent to the bearing 265. The outer wall of the sealing member 28 abuts against the inner wall of the fixing groove 243 to prevent the adhesive from overflowing when flowing from the third cavity 241 to the first cavity 221, and to prevent the adhesive from leaking into the bearing 265 and affecting the service life of the drive device 26.

[0042] The adhesive application device 2 also includes a washer 29, which is sandwiched between the seal 28 and the bearing 265 to prevent interference between the seal 28 and the bearing 265, thus affecting the service life of the drive device 26.

[0043] The second connecting member 25 has a fourth cavity 251, one end of which is connected to the second cavity 231, and the other end is provided with an internal thread. The end of the adhesive applicator 23 away from the adhesive outlet 233 is provided with an external thread. The adhesive applicator 23 and the second connecting member 25 are connected by threads, so that the flow guide 22 and the adhesive applicator 23 are fixedly connected as a whole structure. The second connecting member 25 is fixed to the rotor cover 2631 by bolts, and the rotor assembly 263 drives the flow guide 22, the second connecting member 25 and the adhesive applicator 23 to rotate synchronously and coaxially.

[0044] The advantage of setting the second connector 25 is that the specifications of the adhesive coating part 23 can be easily changed according to actual processing needs, while reducing the maintenance cost of the whole machine.

[0045] The adhesive application device 2 further includes an adjusting member 20, which is threadedly connected to one end of the adhesive application member 23 and is correspondingly disposed with respect to the adhesive outlet 233. The position of the adjusting member 20 relative to the adhesive outlet 233 is adjusted by threading the adjusting member 20 to adjust the amount of adhesive dispensed. Specifically, the inner wall of the second cavity 231 is provided with an internal thread, and the adjusting member 20 is provided with a corresponding external thread. The position of the adjusting member 20 relative to the adhesive outlet 233 is adjusted by threading the adjusting member 20.

[0046] Please refer to the following: Figure 5 and Figure 6 , Figure 5 for Figure 2 The diagram shown is a three-dimensional structural schematic of the adjustment component from one perspective. Figure 6 for Figure 2 The diagram shows a three-dimensional view of the adjusting component from another perspective. One end of the adjusting component 20 has a flow-diverting cavity 201, and the outer surface of the opposite end has a flow-limiting groove 203, which is positioned opposite the glue outlet 233. The flow-diverting cavity 201 is connected to the second cavity 231 through an opening and to the flow-limiting groove 203 through a drainage hole 205. The flow-diverting cavity 201 and the flow-limiting groove 203 work together to adjust the flow rate of the adhesive to prevent overflow.

[0047] It should be noted that the drainage holes 205 are symmetrically distributed around the rotation axis 235 of the adhesive coating component 23, and all the drainage holes 205 are of the same size to balance the centrifugal torque under high-speed rotation. In this embodiment, there are three drainage holes 205. In other embodiments, the number of drainage holes 205 can be increased or decreased, depending on the actual operation requirements.

[0048] The adjusting component 20 is provided with a disassembly hole 207, which is located opposite to the flow divider 201 at both ends of the adjusting component 20. By using a disassembly tool to clamp or hold the disassembly hole 207, the thread adjustment between the adhesive applicator 23 can be conveniently performed without the need for electricity or magnetism to control the flow rate of the adhesive.

[0049] When no glue application is being performed, the position of the adjusting member 20 relative to the glue outlet 233 is adjusted by thread, so that the flow-limiting groove 203 and the glue outlet 233 are not aligned. The glue remains in the flow-limiting groove 203 and cannot flow to the glue outlet 233.

[0050] During the adhesive application process, the position of the adjusting member 20 relative to the adhesive outlet 233 is adjusted by thread, so that the flow-limiting groove 203 partially aligns with the adhesive outlet 233. Under the action of centrifugal force, the adhesive flows from the flow-limiting groove to the adhesive outlet 233 and is thrown onto the inner wall of the workpiece to form a coating layer.

[0051] In summary, the coating equipment provided in this application organically combines the storage container with the power coating component, improving the process integration and making it easier to control the morphology of the ejected fine droplets, resulting in a thinner and more uniform coating layer on the workpiece. At the same time, it expands the types of adhesives, allowing for efficient and uniform coating even with single-component high-temperature adhesives with lower fluidity. The overall structure of the equipment is simple, with higher structural reliability and lower machine maintenance costs.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
