Description

Coating feeding device and coating equipment Technical Field

[0001] This application relates to the field of coating equipment, and more particularly to a coating feeding device and coating equipment having the coating feeding device. Background Technology

[0002] In related technologies, coating equipment is used to coat PCBs (Printed Circuit Boards) with a coating material, such as conformal coating, to protect the PCB and its related structures from environmental corrosion. However, after the coating material is prepared, a large number of air bubbles exist in it. Removing these bubbles by letting it stand for a long time is required, and the bubble removal effect is poor, reducing the utilization rate of the coating material and causing waste. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a coating feeding device that, compared with the prior art, can quickly expel gas from the material to be coated, and can also improve the gas expulsion effect from the material to be coated, thereby effectively increasing the utilization rate of the material to be coated.

[0004] This application also proposes a coating device.

[0005] In a first aspect, embodiments of this application provide a coating feeding device, comprising:

[0006] The first feeding mechanism is used to hold the material to be coated;

[0007] The vacuum mechanism has a vacuum chamber for housing the first feeding mechanism. The vacuum mechanism removes gas from the material to be coated by evacuating the vacuum chamber.

[0008] The fixed base, the first feeding mechanism is adapted to be fixed to the fixed base;

[0009] The second feeding mechanism and the driving mechanism are both located on a fixed base. The second feeding mechanism is connected to the first feeding mechanism, and the driving mechanism is connected to the first feeding mechanism to drive the material to be coated in the first feeding mechanism to flow into the second feeding mechanism.

[0010] In the above technical solution, after the first feeding mechanism containing the material to be coated is placed into the vacuum chamber, the vacuum chamber is evacuated by the vacuum mechanism to remove the gas in the material to be coated in the first feeding mechanism and remove the air bubbles in the material to be coated in the first feeding mechanism. Compared with the prior art, it can quickly remove the gas in the material to be coated and improve the gas removal effect. This is beneficial to make the material to be coated in the first feeding mechanism reach a good usable state, effectively improve the utilization rate of the material to be coated and reduce the waste of the material to be coated.

[0011] In some embodiments, the vacuum level of the vacuum chamber is adjustable; and / or

[0012] The vacuum chamber evacuation time is adjustable.

[0013] In the above technical solution, by adjusting the vacuum level of the vacuum chamber and / or adjusting the vacuum evacuation time of the vacuum chamber, the gas in the material to be coated can be discharged more quickly. The material to be coated after removing bubbles can reach a good working state in a short time, which greatly improves the utilization rate of conformal coating and can improve the efficiency of replenishing material to the coating equipment.

[0014] In some embodiments, the first feeding mechanism includes: a first feeding mechanism body and a piston, the first feeding mechanism body defining a storage space for storing material to be coated, the piston being movably disposed within the storage space along the depth direction of the first feeding mechanism, the storage space having a first end wall, the first end wall and the piston being disposed opposite each other along the depth direction of the first feeding mechanism, the first end wall forming a material outlet communicating with a second feeding mechanism, a drive mechanism connected to the piston, the drive mechanism being adapted to drive the piston to move toward the first end wall so that the material to be coated in the first feeding mechanism flows into the second feeding mechanism through the material outlet.

[0015] In the above technical solution, by cooperating with the main body of the first feeding mechanism, the piston and the driving mechanism, the material to be coated in the first feeding mechanism can be pressed into the second feeding mechanism. This also helps to simplify the structure of the first feeding mechanism and reduce the manufacturing difficulty of the first feeding mechanism. Furthermore, the driving mechanism is located outside the first feeding mechanism and does not come into contact with the material to be coated in the first feeding mechanism, thus reducing the risk of the driving mechanism getting stuck due to contact with the material to be coated.

[0016] In some embodiments, the drive mechanism and the piston are detachably connected.

[0017] In the above technical solution, the drive mechanism and piston are detachably connected, which enables the assembly and disassembly of the drive mechanism and piston. This facilitates the quick assembly and disassembly of the first feeding mechanism, making it easy to remove the first feeding mechanism from the fixed base and to fix it to the fixed base. It also makes it easy to place the first feeding mechanism into the vacuum chamber. In addition, after the first feeding mechanism is removed from the fixed base, it is easy to put the material to be coated into the first feeding mechanism, which facilitates the material changing and feeding of the coating feeding device. It also facilitates the cleaning of the first feeding mechanism, which helps to improve the cleaning efficiency of the first feeding mechanism.

[0018] In some embodiments, the storage space further has a second end wall along the depth direction of the first feeding mechanism. The second end wall is located on the side of the piston away from the first end wall. The second end wall has a mounting through hole. The surface of the piston away from the first end wall has a connecting portion. The connecting portion and the mounting through hole are correspondingly arranged. The driving mechanism is located on the side of the second end wall away from the piston and is connected to the connecting portion.

[0019] In the above technical solution, an assembly through hole is formed on the second end wall, and the connecting part and the assembly through hole are correspondingly arranged, which allows the second end wall to avoid the connecting part, making it easier for the connecting part and the drive mechanism to cooperate and connect, reducing the assembly difficulty of the drive mechanism and the piston, and improving the disassembly and assembly efficiency of the drive mechanism and the piston.

[0020] In some embodiments, the connecting portion includes a first connecting plate and a second connecting plate. The first connecting plate extends along the depth direction of the first feeding mechanism and is connected between the piston and the second connecting plate. The second connecting plate is perpendicular to the first connecting plate and spaced apart from the piston. The second connecting plate has an insertion interface. The driving mechanism has a connector head that is adapted to be inserted into the insertion interface.

[0021] In the above technical solution, the connection head and the second connecting plate are connected and assembled, which makes it easier to disassemble and assemble the drive mechanism and the piston, and facilitates the quick disassembly and assembly of the first feeding mechanism. It also makes it easier for workers to load and change materials. In addition, the connection part has a simple structure, which is easy to manufacture and helps to simplify the structure of the first feeding mechanism. Furthermore, the connector extends to one edge of the second connecting plate through the plug-in interface, which makes it easy to plug the connector head into the plug-in interface.

[0022] In some embodiments, the connector includes: a first limiting plate, a connecting post, and a second limiting plate. The connecting post is connected between the first limiting plate and the second limiting plate to separate the first limiting plate and the second limiting plate. When the connector is inserted into the insertion interface, the connecting post passes through the insertion interface. Along the depth direction of the first feeding mechanism, the first limiting plate and the second limiting plate are located on both sides of the second connecting plate.

[0023] In the above technical solution, the connection between the first limiting plate and the second limiting plate by the connecting post can make the connector structure reasonable, which is conducive to simplifying the connector structure, realizing the detachable connection effect of the connector and the connecting part, and making it easier to insert the connector into the plug interface.

[0024] In some embodiments, the main body of the first feeding mechanism includes: a barrel body, a first end cap and a second end cap. The barrel body is annular and open at both ends along the depth direction of the first feeding mechanism. The first end cap and the second end cap are respectively covered at both ends of the barrel body to define a storage space. The first end cap and the second end cap are detachably connected to the barrel body. At least a portion of the first end cap is a first end wall and at least a portion of the second end cap is a second end wall.

[0025] In the above technical solution, the storage space can be defined by assembling the barrel body, the first end cap, and the second end cap. This also simplifies the main structure of the first feeding mechanism. Since both the first and second end caps are detachably connected to the barrel body, removing the first end cap facilitates adding the material to be coated into the main body of the first feeding mechanism, removing the material to be coated from the main body of the first feeding mechanism, cleaning the main body of the first feeding mechanism, removing the piston from the main body of the first feeding mechanism, and replacing the barrel body, the first end cap, and the second end cap separately, thus reducing the maintenance cost of the first feeding mechanism.

[0026] In some embodiments, the drive mechanism has a push rod movably oriented along the depth direction of the first feeding mechanism, the push rod being connected to a piston.

[0027] In the above technical solution, the driving mechanism has a push rod that can move along the depth direction of the first feeding mechanism. The piston can be driven to move by the push rod moving back and forth along the depth direction of the first feeding mechanism, which helps to reduce the stroke of the driving mechanism when driving the piston.

[0028] In some embodiments, the first feeding mechanism is detachably fixed to the mounting base.

[0029] In the above technical solution, the first feeding mechanism is detachably fixed to the fixed base. Removing the first feeding mechanism from the fixed base facilitates its use. When the first feeding mechanism is feeding material, fixing it to the fixed base improves its positional stability, thereby enhancing the reliability of the connection between the first feeding mechanism and the second feeding mechanism and the drive mechanism.

[0030] In some embodiments, the coating feeding device further includes a clamping structure fixed to a fixed base, the clamping structure being used to clamp or release the first feeding mechanism.

[0031] In the above technical solution, the clamping structure clamps or releases the first feeding mechanism, which makes it easier to disassemble and assemble the first feeding mechanism. This is beneficial to improving the efficiency of adding the material to be coated into the first feeding mechanism, as well as the efficiency of replacing the material to be coated in the first feeding mechanism. It is also beneficial to improve the cleaning efficiency of the first feeding mechanism. Furthermore, the clamping structure is simple in structure, which helps to simplify the structure of the coating feeding device.

[0032] In some embodiments, the coating feeding device further includes: a support base, which is fixed to a fixed base and is assembled with a first feeding mechanism to support the first feeding mechanism. The support base can restrict the movement of the first feeding mechanism.

[0033] In the above technical solution, by setting a support base to support the first feeding mechanism, the support base can restrict the movement of the first feeding mechanism. During the disassembly and assembly of the first feeding mechanism, the second support plate can support the first feeding mechanism, which makes it easier to disassemble and assemble the first feeding mechanism. Through the joint action of the support base and the clamping structure, it is beneficial to improve the positional stability of the first feeding mechanism, so that the first feeding mechanism can be reliably fixed to the fixed base.

[0034] In some embodiments, the coating feeding device further includes: a waste box; the second feeding mechanism includes a first valve body and a discharge flow path; the first valve body has a first valve body inlet, a first valve body outlet and a first valve body discharge port; the first valve body inlet is connected to the first feeding mechanism; the first valve body outlet is connected to the discharge flow path; the first valve body discharge port is connected to the waste box; and the first valve body inlet is selectively connected to either the first valve body outlet or the first valve body discharge port.

[0035] In the above technical solution, by setting up a waste box, a first valve body and a discharge flow path, the gas in the first feeding mechanism can be discharged into the waste box, reducing the risk of the coating feeding device mixing gas into the material to be coated during the feeding process, and helping to achieve the effect of not mixing gas into the material to be coated during the entire feeding process.

[0036] In some embodiments, there are multiple first feeding mechanisms and multiple first valve bodies, and the multiple first feeding mechanisms and multiple first valve bodies are connected in a one-to-one correspondence, and the discharge ports of the multiple first valve bodies are all connected to the waste box.

[0037] In the above technical solution, by setting up multiple first feeding mechanisms and multiple first valve bodies, and connecting the multiple first feeding mechanisms and multiple first valve bodies one by one, during the coating process, it is possible to select a single first feeding mechanism to supply material, or to select multiple first feeding mechanisms to supply material simultaneously. This allows for flexible control of the amount of material to be coated, thereby improving the utilization rate of the material to be coated. It can meet the needs of small-batch prototyping for flexible use of the amount of material to be coated, and also meet the needs of different products for changing the type of material to be coated.

[0038] In some embodiments, the discharge flow path includes: a second valve body and a discharge pipeline. The second valve body has a second valve body discharge port and a plurality of second valve body inlets. The second valve body discharge port is connected to the discharge pipeline, and the plurality of second valve body inlets are respectively connected to the first valve body discharge ports of a plurality of first valve bodies.

[0039] In the above technical solution, by setting a second valve body and a discharge pipeline, the discharge port of the second valve body can be connected to at least one second valve body inlet, so that the feeding effect of at least one first feeding mechanism can be adjusted according to the actual coating needs to allow different numbers of first feeding mechanisms to participate in feeding, which is beneficial to improving the versatility of the coating feeding device.

[0040] In some embodiments, the coating feeding device further includes a flow detection mechanism, which is mounted on a fixed base and cooperates with the discharge flow path to detect the flow rate of the material to be coated in the discharge flow path.

[0041] In the above technical solution, by setting up a flow detection mechanism, the amount of material to be coated can be monitored and stored in real time during the coating process. The flow detection mechanism is bound to the MES system. When the flow rate of the material to be coated deviates, the MES system can control the alarm device to sound an alarm in time, reducing the risk of defects in batch products.

[0042] Secondly, embodiments of this application also provide a coating apparatus, including the coating feeding device described above.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0079] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0080] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0081] In this application, "multiple" means two or more (including two).

[0082] In this embodiment, the coating equipment is a device for coating a PCB board with a material to be coated. The coating equipment has a coating mechanism that coats the PCB board with the material to be coated. The coating mechanism can be a coating nozzle or similar structure. The coating equipment also has a coating feeding device that is connected to the coating mechanism and supplies the material to be coated to the coating mechanism. However, after the material to be coated is prepared, a large number of air bubbles exist in the material. Removing the air bubbles by letting it stand takes a long time and the bubble removal effect is poor, which reduces the utilization rate of the material to be coated and causes waste of the material to be coated.

[0083] Based on the above considerations, and to address the issues of long degassing time and poor degassing effect of the material to be coated, a coating feeding device was designed after in-depth research. The device includes: a first feeding mechanism for holding the material to be coated; a vacuum mechanism forming a vacuum chamber for housing the first feeding mechanism, which evacuates the vacuum chamber to expel gas from the material to be coated; a fixed base for fixing the first feeding mechanism; and a second feeding mechanism and a driving mechanism, both located on the fixed base and connected to the first feeding mechanism. The driving mechanism is connected to the first feeding mechanism to drive the material to be coated from the first feeding mechanism into the second feeding mechanism. By evacuating the vacuum chamber through the vacuum mechanism to expel gas from the material to be coated in the first feeding mechanism, compared to existing technologies, the device can quickly expel gas from the material to be coated, improving the gas expulsion effect and ensuring the material in the first feeding mechanism reaches a usable state. This effectively increases the utilization rate of the material to be coated and reduces waste.

[0084] The coating feeding device according to an embodiment of this application is described below with reference to Figures 1-13. The coating feeding device is applied to a coating equipment. This application takes the coating equipment coating conformal coating on a PCB board as an example for illustration.

[0085] As shown in Figures 1-13, the coating feeding device according to an embodiment of this application includes: a first feeding mechanism 10, which is used to hold the material to be coated; a vacuum mechanism 20, which forms a vacuum chamber 21 for placing the first feeding mechanism 10, and the vacuum mechanism 20 evacuates the vacuum chamber 21 to expel gas from the material to be coated; a fixed base 30, on which the first feeding mechanism 10 is adapted to be fixed; a second feeding mechanism 40 and a driving mechanism 50, both of which are disposed on the fixed base 30, the second feeding mechanism 40 and the first feeding mechanism 10 are connected, and the driving mechanism 50 is connected to the first feeding mechanism 10 to drive the material to be coated in the first feeding mechanism 10 to flow into the second feeding mechanism 40.

[0086] The coating feeding device includes a first feeding mechanism 10, a vacuum mechanism 20, a fixed base 30, a second feeding mechanism 40, and a drive mechanism 50. The first feeding mechanism 10 can be a feeding hopper used to hold the material to be coated. The material to be coated can be conformal coating, a type of paint used to protect the PCB board and its related structures from environmental corrosion. Conformal coating has good high and low temperature resistance. After curing, it forms a transparent protective film with superior insulation, moisture resistance, leakage prevention, shock resistance, dust resistance, corrosion resistance, aging resistance, and corona resistance. The material to be coated is placed into the first feeding mechanism 10 after preparation.

[0087] It should be noted that some conformal coatings require mixing according to viscosity requirements before application. During the mixing process, the mechanical motion of stirring and mixing generates a large number of air bubbles in the conformal coating. These bubbles generally need to be removed by allowing the coating to stand. Due to the viscosity, the natural dissipation of gas in the conformal coating takes a long time, usually about one hour, and the bubble removal effect is generally not significant. As a result, when the conformal coating is applied to the PCB board surface, several air bubbles will remain, affecting the effectiveness of the conformal coating.

[0088] The vacuum mechanism 20 forms a vacuum chamber 21, which is a sealed cavity. The first feeding mechanism 10, which contains the material to be coated, can be placed inside the vacuum chamber 21. The vacuum mechanism 20 can evacuate the vacuum chamber 21 to create a vacuum environment. When the first feeding mechanism 10 is placed inside the vacuum chamber 21 and the vacuum chamber 21 is evacuated, the first feeding mechanism 10 is evacuated. Under the action of the pressure difference, the gas in the material to be coated can be discharged, reducing the risk of air bubbles in the material to be coated. Compared with the prior art, it can quickly discharge the gas in the material to be coated and improve the gas discharge effect. This is beneficial to making the material to be coated in the first feeding mechanism 10 reach a good usable state, effectively improving the utilization rate of the material to be coated and reducing waste.

[0089] In some examples, as shown in Figures 11 and 13, the vacuum mechanism 20 may include a cabinet 22, a vacuum pump 23, a vacuum filter 24, a vacuum tubing, a pressure gauge, a timer, and an adjustment button 28. The cabinet 22 may be made of metal; for example, it may be made of stainless steel, iron, or similar materials. The cabinet 22 defines a vacuum chamber 21. The surface of the vacuum chamber 21 may be polished to reduce the risk of coating residue remaining on its surface and to simplify cleaning. The cabinet 22 may have a sealing cover 29 for opening or closing the vacuum chamber 21. The top wall of the vacuum chamber 21 may be fitted with the sealing cover 29, which is movably connected to the cabinet 22, allowing it to open or close the vacuum chamber 21. In some examples, one end of the sealing cover 29 is rotatably mounted on the cabinet 22, allowing rotation of the sealing cover 29 to open or close the vacuum chamber 21. A sealing ring, which can be made of rubber, can be provided on the inner surface of the sealing cover 29. The inner surface of the sealing cover 29 is the surface facing the vacuum chamber 21 when the vacuum chamber 21 is closed. The sealing ring can be set around the edge of the sealing cover 29. When the vacuum chamber 21 is closed, the sealing ring can abut against the cabinet 22, thereby sealing the gap between the sealing cover 29 and the cabinet 22, thus improving the sealing performance of the vacuum chamber 21. A pressure gauge can display the air pressure inside the vacuum chamber 21, making it easy for operators to understand the air pressure inside the vacuum chamber 21. A timer can keep track of the time, thereby controlling the evacuation time of the vacuum chamber 21.

[0090] As shown in Figure 11, the vacuum mechanism 20 may further include a locking element 291, which is located in the cabinet 22. The locking element 291 is used to lock or unlock the sealing cover 29. When the sealing cover 29 closes the vacuum chamber 21, the locking element 291 can lock the sealing cover 29, thereby reliably closing the vacuum chamber 21. When it is necessary to open the vacuum chamber 21, the locking element 291 unlocks the sealing cover 29, and rotating the sealing cover 29 opens the vacuum chamber 21, allowing the first feeding mechanism 10 to be inserted into the vacuum chamber 21 through the open opening. The locking element 291 can be configured as a manual locking structure, allowing the sealing cover 29 to be locked or unlocked manually. The locking element 291 can also be configured as an electric locking structure, achieving the effect of automatically driving the locking element 291 to lock or unlock the sealing cover 29. In some examples, as shown in Figure 11, the locking element 291 can be configured as a locking handle, which is rotatably disposed on the surface of the sealing cover 29 facing away from the vacuum chamber 21. A fixing block 292 can be disposed on the corresponding surface of the cabinet 22. When the sealing cover 29 closes the vacuum chamber 21, the locking handle is rotated to a position opposite to the fixing block 292, fixing the locking handle to the fixing block 292 and thus locking the sealing cover 29. When it is necessary to open the vacuum chamber 21, the locking handle is rotated to separate the locking handle from the fixing block 292, thereby unlocking the sealing cover 29.

[0091] The first feeding mechanism 10 is adapted to be fixed to the fixed base 30. The fixed base 30 and the vacuum mechanism 20 can be separate parts. After the material to be coated is placed into the first feeding mechanism 10, the first feeding mechanism 10 is first placed into the vacuum chamber 21 to evacuate the air bubbles in the material to be coated. Then the first feeding mechanism 10 is taken out from the vacuum chamber 21. After taking out the first feeding mechanism 10, the first feeding mechanism 10 is fixed to the fixed base 30. The first feeding mechanism 10 and the fixed base 30 are detachably connected. The first feeding mechanism 10 can be snapped and fixed to the fixed base 30, or the first feeding mechanism 10 can be fixed to the fixed base 30 by bolts.

[0092] The second feeding mechanism 40 can be snapped and fixed to the fixed base 30, or it can be fixed to the fixed base 30 by bolts. When the first feeding mechanism 10 is fixed to the fixed base 30, the second feeding mechanism 40 is connected to the first feeding mechanism 10, and it is also connected to the coating mechanism. In some examples, the second feeding mechanism 40 can be constructed as a pipeline structure. The drive mechanism 50 can be snapped and fixed to the fixed base 30, or it can be fixed to the fixed base 30 by bolts. In some examples, the drive mechanism 50 can be constructed as a cylinder push rod 55, a linear motor, or other structures. The drive mechanism 50 is connected to the first feeding mechanism 10. In some examples, the first feeding mechanism 10 may be provided with a movable part. The drive mechanism 50 is connected to the movable part. The drive mechanism 50 can drive the movable part to move linearly to press the material to be coated in the first feeding mechanism 10 into the second feeding mechanism 40. The material to be coated flowing into the second feeding mechanism 40 can flow along the second feeding mechanism 40 to the coating mechanism, thereby realizing the coating of the material to be coated.

[0093] Specifically, after the material to be coated is prepared, it is placed into the first feeding mechanism 10, which is then placed into the vacuum chamber 21. The first feeding mechanism 10 is opened to evacuate the vacuum chamber 21, expelling air bubbles from the material to be coated. The first feeding mechanism 10 is then closed and removed from the vacuum chamber 21. After removal, the first feeding mechanism 10 is fixed to the fixing base 30, connecting the first feeding mechanism 10 and the second feeding mechanism 40. The driving mechanism 50 is connected to the movable part of the first feeding mechanism 10. The driving mechanism 50 can drive the movable part to move linearly, pressing the material to be coated in the first feeding mechanism 10 into the second feeding mechanism 40. The material to be coated flowing into the second feeding mechanism 40 can flow along the second feeding mechanism 40 to the coating mechanism, thereby achieving the coating of the material to be coated.

[0094] In the above technical solution, after the first feeding mechanism 10 containing the material to be coated is placed into the vacuum chamber 21, the vacuum mechanism 20 evacuates the vacuum chamber 21 to remove the gas in the material to be coated in the first feeding mechanism 10, thereby removing air bubbles in the material to be coated in the first feeding mechanism 10. Compared with the prior art, it can quickly remove the gas in the material to be coated and improve the gas removal effect, which is conducive to making the material to be coated in the first feeding mechanism 10 reach a good usable state, effectively improving the utilization rate of the material to be coated and reducing the waste of the material to be coated.

[0095] According to some embodiments of this application, the vacuum level of the vacuum chamber 21 is adjustable; and / or the evacuation time of the vacuum chamber 21 is adjustable.

[0096] The negative pressure value inside the vacuum chamber 21 is changed by adjusting the vacuum level of the vacuum chamber 21. In some examples, the vacuum level of the vacuum chamber 21 is adjustable, and the evacuation time of the vacuum chamber 21 is adjustable. In other examples, the vacuum level of the vacuum chamber 21 is adjustable. In still other examples, the evacuation time of the vacuum chamber 21 is adjustable. This application describes an example where both the vacuum level and the evacuation time of the vacuum chamber 21 are adjustable. The vacuum level and evacuation time of the vacuum chamber 21 can be adjusted using the adjustment button 28.

[0097] Based on the viscosity, volume, and other characteristics of the material to be coated, the vacuum level in the vacuum chamber 21 is adjusted to a suitable value, and the vacuuming time of the vacuum chamber 21 is also adjusted to a suitable value. This allows for faster removal of gas from the material to be coated, and the material to be coated, after removing air bubbles, can reach a good working state within a short time (time can be t, 0min < t ≤ 3min), greatly improving the utilization rate of the conformal coating. Due to the increased efficiency of gas removal from the material to be coated, the efficiency of replenishing the coating equipment can be improved.

[0098] In the above technical solution, by adjusting the vacuum level of the vacuum chamber 21 and / or adjusting the vacuuming time of the vacuum chamber 21, the gas in the material to be coated can be discharged more quickly. The material to be coated after removing bubbles can reach a good working state in a short time, which greatly improves the utilization rate of the conformal coating and can improve the efficiency of replenishing the coating equipment.

[0099] According to some embodiments of this application, as shown in Figures 8-10, the first feeding mechanism 10 includes: a first feeding mechanism body 11 and a piston 12. The first feeding mechanism body 11 defines a storage space 111 for storing the material to be coated. The piston 12 is movably disposed in the storage space 111 along the depth direction of the first feeding mechanism 10. The storage space 111 has a first end wall 112. The first end wall 112 and the piston 12 are disposed opposite to each other along the depth direction of the first feeding mechanism 10. The first end wall 112 forms a material outlet 113 that communicates with the second feeding mechanism 40. A drive mechanism 50 is connected to the piston 12. The drive mechanism 50 is adapted to drive the piston 12 to move toward the first end wall 112 so that the material to be coated in the first feeding mechanism 10 flows into the second feeding mechanism 40 through the material outlet 113.

[0100] The first feeding mechanism 10 includes a first feeding mechanism body 11 and a piston 12. The first feeding mechanism body 11 defines a storage space 111 for storing the material to be coated. The piston 12 is the movable part in the above embodiment. The piston 12 is located within the storage space 111 and is movably disposed within the storage space 111 along the depth direction of the first feeding mechanism 10. When the first feeding mechanism 10 is placed in the direction shown in FIG. 10, the depth direction of the first feeding mechanism 10 is the Z direction in FIG. 10. The storage space 111 has a first end wall 112, which is the structure of the first feeding mechanism body 11. The first end wall 112 and the piston 12 are disposed opposite each other along the depth direction of the first feeding mechanism 10, and the material to be coated in the first feeding mechanism 10 is located between the piston 12 and the first end wall 112.

[0101] The first end wall 112 has a material outlet 113, which penetrates the first end wall 112 along its thickness direction. The material outlet 113 connects the second feeding mechanism 40 and the storage space 111. The drive mechanism 50 is connected to the piston 12. The drive mechanism 50 can be directly connected to the piston 12, or indirectly connected to the piston 12 via an adapter. The drive mechanism 50 is located outside the storage space 111 and on the side of the piston 12 away from the first end wall 112. The drive mechanism 50 can drive the piston 12 to move along the depth direction of the first feeding mechanism 10. When the drive mechanism 50 drives the piston 12 to move towards the first end wall 112, the piston 12 can push the material to be coated towards the first end wall 112, thereby allowing the material to be coated in the first feeding mechanism 10 to flow into the second feeding mechanism 40 through the material outlet 113.

[0102] Specifically, the first feeding mechanism 10 is fixed to the fixed base 30, the second feeding mechanism 40 is connected to the material outlet 113, the second feeding mechanism 40 connects the storage space 111 and the second feeding mechanism 40, the driving mechanism 50 can drive the piston 12 to move towards the first end wall 112, press the material to be coated in the first feeding mechanism 10 into the second feeding mechanism 40, and the material to be coated flowing into the second feeding mechanism 40 can flow along the second feeding mechanism 40 to the coating mechanism, thereby realizing the coating of the material to be coated.

[0103] In the above technical solution, by cooperating with the main body 11 of the first feeding mechanism, the piston 12 and the driving mechanism 50, the material to be coated in the first feeding mechanism 10 can be pressed into the second feeding mechanism 40. This also helps to simplify the structure of the first feeding mechanism 10 and reduce the manufacturing difficulty of the first feeding mechanism 10. Furthermore, the driving mechanism 50 is located outside the first feeding mechanism 10 and does not come into contact with the material to be coated in the first feeding mechanism 10, thus reducing the risk of the driving mechanism 50 getting stuck due to contact with the material to be coated.

[0104] According to some embodiments of this application, as shown in Figures 8 and 9, the drive mechanism 50 and the piston 12 are detachably connected.

[0105] The drive mechanism 50 can be snapped into the piston 12, or the drive mechanism 50 can be fixedly connected to the piston 12 by bolts.

[0106] In the above technical solution, the drive mechanism 50 and piston 12 are detachably connected, which enables the assembly and disassembly of the drive mechanism 50 and piston 12. This facilitates the quick assembly and disassembly of the first feeding mechanism 10, making it easy to remove the first feeding mechanism 10 from the fixed base 30 and to fix the first feeding mechanism 10 to the fixed base 30. It also makes it easy to place the first feeding mechanism 10 into the vacuum chamber 21. In addition, after the first feeding mechanism 10 is removed from the fixed base 30, it is also easy to put the material to be coated into the first feeding mechanism 10, thereby facilitating the material changing and feeding of the coating feeding device, and also facilitating the cleaning of the first feeding mechanism 10, which helps to improve the cleaning efficiency of the first feeding mechanism 10.

[0107] According to some embodiments of this application, as shown in Figures 8-10, the storage space 111 further has a second end wall 114. Along the depth direction of the first feeding mechanism 10, the second end wall 114 is located on the side of the piston 12 away from the first end wall 112. The second end wall 114 is formed with a mounting through hole 115. The surface of the piston 12 away from the first end wall 112 has a connecting portion 121. The connecting portion 121 and the mounting through hole 115 are correspondingly arranged. The driving mechanism 50 is located on the side of the second end wall 114 away from the piston 12 and is connected to the connecting portion 121.

[0108] The storage space 111 also has a second end wall 114, which is the structure of the main body 11 of the first feeding mechanism. The second end wall 114 and the piston 12 are arranged opposite each other along the depth direction of the first feeding mechanism 10. The second end wall 114 is located on the side of the piston 12 away from the first end wall 112, and the piston 12 is located between the first end wall 112 and the second end wall 114. The second end wall 114 has a mounting through hole 115, which penetrates the second end wall 114 along its thickness direction. The piston 12 is located on the surface away from the first end wall 112. The surface has a connecting part 121, which is fixed to the piston 12. The connecting part 121 and the mounting through hole 115 are correspondingly arranged along the depth direction of the first feeding mechanism 10. When the piston 12 moves, the piston 12 can drive the connecting part 121 to move into or out of the mounting through hole 115. Along the depth direction of the first feeding mechanism 10, the driving mechanism 50 is located on the side of the second end wall 114 away from the piston 12, and the driving mechanism 50 is connected to the connecting part 121. The connection between the driving mechanism 50 and the piston 12 is achieved through the connection between the driving mechanism 50 and the connecting part 121.

[0109] In the above technical solution, an assembly through hole 115 is formed in the second end wall 114, and the connecting part 121 and the assembly through hole 115 are correspondingly arranged, which enables the second end wall 114 to avoid the connecting part 121, making it easier for the connecting part 121 and the drive mechanism 50 to cooperate and connect, reducing the assembly difficulty of the drive mechanism 50 and the piston 12, and improving the disassembly and assembly efficiency of the drive mechanism 50 and the piston 12.

[0110] According to some embodiments of this application, as shown in FIG10, the connecting part 121 includes a first connecting plate 122 and a second connecting plate 123. The first connecting plate 122 extends along the depth direction of the first feeding mechanism 10 and is connected between the piston 12 and the second connecting plate 123. The second connecting plate 123 is perpendicular to the first connecting plate 122 and spaced apart from the piston 12. The second connecting plate 123 forms an insertion interface 124. The driving mechanism 50 has a connector 51, which is adapted to be inserted into the insertion interface 124.

[0111] The connecting portion 121 includes a first connecting plate 122 and a second connecting plate 123, which are fixedly connected. The first connecting plate 122 extends along the depth direction of the first feeding mechanism 10. The end of the first connecting plate 122 facing the piston 12 is fixedly connected to the piston 12, and the end of the first connecting plate 122 away from the piston 12 is connected to the second connecting plate 123. The second connecting plate 123 is perpendicular or substantially perpendicular to the first connecting plate 122. Along the depth direction of the first feeding mechanism 10, the second connecting plate 123 is spaced apart from the piston 12 and can be parallel to the piston 12. The second connecting plate 123 has a insertion interface 124. As an example, the insertion interface 124 is located in the middle of the second connecting plate 123 and extends through the second connecting plate 123. As another example, the insertion interface 124 extends through the second connecting plate 123 and extends to one edge of the second connecting plate 123. This application uses the example of a connector 124 penetrating through the second connecting plate 123 and extending to one edge of the second connecting plate 123.

[0112] The drive mechanism 50 has a connector 51, which can be inserted into the connector 124. The connector 51 can be matched with the second connecting plate 123 for limiting, or it can be interference-fitted into the connector 124, thereby connecting the connector 51 and the connecting part 121, and thus connecting the drive mechanism 50 and the piston 12. The connector 51 can also be removed from the connector 124, at which point the connector 51 and the connecting part 121 are separated, and the drive mechanism 50 and the piston 12 are disassembled.

[0113] In the above technical solution, the connection head 51 and the second connecting plate 123 are connected and assembled, which makes it easier to disassemble and assemble the drive mechanism 50 and the piston 12, and is more conducive to the quick disassembly and assembly of the first feeding mechanism 10. It is also more convenient for workers to load and change materials. In addition, the connection part 121 has a simple structure, which is easy to manufacture and helps to simplify the structure of the first feeding mechanism 10. Furthermore, the insertion interface 124 extends to one edge of the second connecting plate 123, which makes it easy to insert the connection head 51 into the insertion interface 124.

[0114] According to some embodiments of this application, as shown in FIG10, the connector 51 includes: a first limiting plate 52, a connecting post 53, and a second limiting plate 54. The connecting post 53 is connected between the first limiting plate 52 and the second limiting plate 54 to separate the first limiting plate 52 and the second limiting plate 54. When the connector 51 is inserted into the insertion interface 124, the connecting post 53 passes through the insertion interface 124. Along the depth direction of the first feeding mechanism 10, the first limiting plate 52 and the second limiting plate 54 are respectively located on both sides of the second connecting plate 123.

[0115] As shown in Figure 10, the connector 51 includes a first limiting plate 52, a connecting post 53, and a second limiting plate 54. The first limiting plate 52 and the second limiting plate 54 are opposite to each other and spaced apart along the moving direction of the piston 12. The moving direction of the piston 12 is the depth direction of the first feeding mechanism 10. The connecting post 53 is located between the first limiting plate 52 and the second limiting plate 54. The two ends of the connecting post 53 are fixedly connected to the first limiting plate 52 and the second limiting plate 54, respectively. The first limiting plate 52, the connecting post 53, and the second limiting plate 54 can be integrally formed. The first limiting plate 52 is located at the end of the connecting post 53 facing the piston 12. When the connector 51 needs to be inserted into the insertion interface 124, the connecting post 53 moves into the insertion interface 124 from the open end of the insertion interface 124. The connecting post 53 passes through the insertion interface 124. Along the depth direction of the first feeding mechanism 10, the first limiting plate 52 is located on the side of the second connecting plate 123 facing the piston 12, and the second limiting plate 54 is located on the side of the second connecting plate 123 away from the piston 12. Both the first limiting plate 52 and the second limiting plate 54 can abut and limit the second connecting plate 123. The cross-sectional area of ​​the first limiting plate 52 and the cross-sectional area of ​​the second limiting plate 54 are both larger than the cross-sectional area of ​​the connecting post 53.

[0116] When the drive mechanism 50 drives the piston 12 to move toward the first end wall 112, the second limiting plate 54 can push the second connecting plate 123 to move the piston 12 toward the first end wall 112. When the drive mechanism 50 drives the piston 12 to move toward the second end wall 114, the first limiting plate 52 can push the second connecting plate 123 to move the piston 12 toward the second end wall 114, thereby achieving the effect of the drive mechanism 50 driving the piston 12 to reciprocate along the depth direction of the first feeding mechanism 10.

[0117] In the above technical solution, the connection between the first limiting plate 52 and the second limiting plate 54 by the connecting post 53 makes the structure of the connector 51 reasonable, which helps to simplify the structure of the connector 51, realize the detachable connection effect of the connector 51 and the connecting part 121, and make it easier to insert the connector 51 into the plug interface 124.

[0118] According to some embodiments of this application, as shown in FIG10, the main body 11 of the first feeding mechanism includes: a barrel body 116, a first end cap 117 and a second end cap 118. The barrel body 116 is annular, and both ends of the barrel body 116 are open along the depth direction of the first feeding mechanism 10. The first end cap 117 and the second end cap 118 are respectively covered on both ends of the barrel body 116 to define the storage space 111. The first end cap 117 and the second end cap 118 are both detachably connected to the barrel body 116. At least a portion of the first end cap 117 is a first end wall 112, and at least a portion of the second end cap 118 is a second end wall 114.

[0119] As shown in Figure 10, the main body 11 of the first feeding mechanism includes: a barrel body 116, a first end cap 117, and a second end cap 118. The barrel body 116 is annular and has open ends along the depth direction of the first feeding mechanism 10. The first end cap 117 is placed on the end of the barrel body 116 away from the driving mechanism 50, and the second end cap 118 is placed on the end of the barrel body 116 facing the driving mechanism 50. The end of the barrel body 116 away from the driving mechanism 50 is the upper end of the barrel body 116, and the end of the barrel body 116 facing the driving mechanism 50 is the lower end of the barrel body 116. The first end cap 117 and the second end cap 118 respectively close the two open ends of the barrel body 116, so that the barrel body 116, the first end cap 117, and the second end cap 118 together define the storage space 111. Both the first end cap 117 and the second end cap 118 can be threadedly fixed to the barrel body 116, so that both the first end cap 117 and the second end cap 118 are detachably connected to the barrel body 116. Alternatively, both the first end cap 117 and the second end cap 118 can be bolted to the barrel body 116, so that both the first end cap 117 and the second end cap 118 are detachably connected to the barrel body 116. The first end cap 117 has a first end wall 112, and the second end cap 118 has a second end wall 114.

[0120] The outer peripheral wall of the piston 12 can be provided with a sealing structure. The sealing structure can be annular and can be sleeved on the piston 12. The sealing structure abuts against the inner surface of the barrel 116. The sealing structure can seal the gap between the piston 12 and the inner surface of the barrel 116, reducing the risk of the material to be coated flowing to the side of the piston 12 away from the first end wall 112.

[0121] In the above technical solution, the storage space 111 can be defined by the cooperation of the barrel body 116, the first end cap 117 and the second end cap 118. This also simplifies the structure of the main body 11 of the first feeding mechanism. Since the first end cap 117 and the second end cap 118 are detachably connected to the barrel body 116, removing the first end cap 117 makes it easy to add the material to be coated into the main body 11 of the first feeding mechanism, and also makes it easy to remove the material to be coated from the main body 11 of the first feeding mechanism. It also makes it easy to clean the main body 11 of the first feeding mechanism, and also makes it easy to remove the piston 12 from the main body 11 of the first feeding mechanism. Furthermore, it also makes it easy to replace the barrel body 116, the first end cap 117 and the second end cap 118 separately, thereby reducing the maintenance cost of the first feeding mechanism 10.

[0122] According to some embodiments of this application, as shown in Figures 5 and 9, the drive mechanism 50 has a push rod 55 movably oriented along the depth direction of the first feeding mechanism 10, and the push rod 55 is connected to the piston 12.

[0123] The drive mechanism 50 can be a cylinder push rod 55, a hydraulic push rod 55, or other structures. When the drive mechanism 50 is a cylinder push rod 55 or a hydraulic push rod 55, the moving rod of the cylinder push rod 55 or the moving rod of the hydraulic push rod 55 is constructed as a push rod 55. The drive mechanism 50 can also be a linear motor. When the drive mechanism 50 is a linear motor, the moving shaft of the linear motor is constructed as a push rod 55. The push rod 55 is the structure of the drive mechanism 50 that moves linearly. The connector 51 can be fixed to the free end of the push rod 55. The connector 51 can be fixed to the push rod 55 by bolts, or the connector 51 can be snapped onto the push rod 55. The push rod 55 is connected to the connecting part 121 of the piston 12 through the connector 51, thereby achieving the connection effect between the push rod 55 and the piston 12.

[0124] The cylinder push rod 55 uses compressed air as its power source. Compressed air enters the cylinder through an air pipe, causing the push rod 55 to move linearly. The positive pressure feeding method of the push rod 55 enriches the application scenarios of coating materials, such as small-batch sampling and coating verification tests, and can achieve effective feeding even when the amount of material to be coated is small. The first feeding mechanism 10 can be equipped with multiple liquid level sensors, and alarm liquid levels can be set according to the material usage requirements to promptly replace materials or fillers.

[0125] In the above technical solution, the drive mechanism 50 has a push rod 55 that is movable along the depth direction of the first feeding mechanism 10. The movement of the piston 12 can be achieved by the push rod 55 reciprocating along the depth direction of the first feeding mechanism 10, which helps to reduce the stroke of the drive mechanism 50 when driving the piston 12.

[0126] According to some embodiments of this application, as shown in Figures 3 and 4, the first feeding mechanism 10 is detachably fixed to the fixed base 30.

[0127] The first feeding mechanism 10 can be detachably fixed to the fixed base 30 by bolts. Alternatively, the first feeding mechanism 10 can be snapped onto the fixed base 30. Removing the first feeding mechanism 10 from the fixed base 30 makes it easier to add the material to be coated into the first feeding mechanism 10, easier to replace the material, and easier to clean the first feeding mechanism 10. When the first feeding mechanism 10 is feeding material, fixing it to the fixed base 30 reduces the risk of shaking or tipping, improves its positional stability, and thus enhances the reliability of the connection between the first feeding mechanism 10 and the second feeding mechanism 40 and the drive mechanism 50.

[0128] In the above technical solution, the first feeding mechanism 10 is detachably fixed to the fixed base 30. After the first feeding mechanism 10 is removed from the fixed base 30, it is convenient to use the first feeding mechanism 10. When the first feeding mechanism 10 is feeding material, fixing the first feeding mechanism 10 to the fixed base 30 helps to improve the positional stability of the first feeding mechanism 10, thereby improving the reliability of the connection between the first feeding mechanism 10 and the second feeding mechanism 40 and the drive mechanism 50.

[0129] According to some embodiments of this application, as shown in Figures 4, 8 and 9, the coating feeding device further includes: a clamping structure, which is fixed to the fixed base 30, and is used to clamp or release the first feeding mechanism 10.

[0130] The clamping structure can be fixed to the fixing base 30 by bolts, clamping structure can be fixed to the fixing base 30 by snapping, or clamping structure can be fixed to the fixing base 30 by adhesive. This application does not make specific limitations, as long as the clamping structure is fixed to the fixing base 30.

[0131] As an example, the clamping structure can be constructed as a claw structure, which may include two intersecting sub-claws that are rotatably connected. The first feeding mechanism 10 can be clamped or released by the two sub-claws. When the first feeding mechanism 10 is clamped by the two sub-claws, the first feeding mechanism 10 can be fixed to the fixed base 30.

[0132] As another example, as shown in Figures 4, 8, and 9, the clamping structure includes a first clamping structure 60 and a second clamping structure 70. Both the first clamping structure 60 and the second clamping structure 70 are block structures. The first clamping structure 60 is fixed to the fixed base 30. The second clamping structure 70 is arranged opposite to the first clamping structure 60, with the second clamping structure 70 located on the side of the first clamping structure 60 away from the fixed base 30. The first clamping structure 60 is located between the second clamping structure 70 and the fixed base 30. The second clamping structure 70 has a first end and a second end. The first end of the second clamping structure 70 is rotatably disposed on the first clamping structure 60 about a rotation axis, which can be parallel to the depth direction of the first feeding mechanism 10. The second end of the second clamping structure 70 is detachably connected to the first clamping structure 60. The second end of the second clamping structure 70 is detachably connected to the first clamping structure 60 through a locking structure 72. The locking structure 72 can lock or unlock the second end of the second clamping structure 70 from the first clamping structure 60. The structure of the locking structure 72 is not specifically limited, as long as the locking structure 72 can lock or unlock the second clamping structure 70 and the first clamping structure 60.

[0133] The first clamping structure 60 has a first clamping opening 61, and the second clamping structure 70 has a second clamping opening 71. When the second clamping structure 70 is locked to the first clamping structure 60, the first clamping opening 61 is located on the side of the first clamping structure 60 facing the second clamping structure 70, and the second clamping opening 71 is located on the side of the second clamping structure 70 facing the first clamping structure 60. The first clamping opening 61 and the second clamping opening 71 form a clamping hole. The first feeding mechanism 10 passes through the clamping hole, so that the clamping structure clamps and fixes the first feeding mechanism 10 to the fixed base 30.

[0134] If the first feeding mechanism 10 needs to be removed, unlock the locking structure 72 and rotate the second clamping structure 70 away from the first clamping structure 60 to remove the first feeding mechanism 10. If the first feeding mechanism 10 needs to be fixed to the fixing base 30, first assemble the first feeding mechanism 10 into the first clamping port 61, then rotate the second clamping structure 70 towards the first clamping structure 60 so that the first feeding mechanism 10 is assembled into the second clamping port 71. Lock the locking structure 72 to fix the first clamping structure 60 and the second clamping structure 70, thereby clamping the first feeding mechanism 10 with the first clamping structure 60 and the second clamping structure 70, achieving the effect of fixing the first feeding mechanism 10 to the fixing base 30.

[0135] In the above technical solution, by clamping or releasing the first feeding mechanism 10 through the clamping structure, it is easier to disassemble and assemble the first feeding mechanism 10, which is conducive to improving the efficiency of adding the material to be coated into the first feeding mechanism 10, improving the efficiency of replacing the material to be coated in the first feeding mechanism 10, and improving the cleaning efficiency of the first feeding mechanism 10. In addition, the clamping structure is simple and helps to simplify the structure of the coating feeding device.

[0136] According to some embodiments of this application, as shown in Figures 4 and 9, the coating feeding device further includes: a support base 80, which is fixed to the fixed base 30. The support base 80 is assembled with the first feeding mechanism 10 to support the first feeding mechanism 10, and the support base 80 can restrict the movement of the first feeding mechanism 10.

[0137] The coating feeding device may further include a support base 80, which can be fixedly installed on the fixed base 30 by bolts or by snap-fit. When the coating feeding device is placed in the direction shown in Figure 3, the support base 80 and the clamping structure are located on the same side of the fixed base 30. The support base 80 may be located below the clamping structure. The support base 80 is assembled with the first feeding mechanism 10, and at least a portion of the support base 80 is located below the first feeding mechanism 10. The support base 80 can support the first feeding mechanism 10, reducing the risk of the first feeding mechanism 10 moving downward. Furthermore, the support base 80 can abut against the barrel 116 of the first feeding mechanism 10, which can restrict the first feeding mechanism 10 from moving toward the fixed base 30.

[0138] In some examples, the support base 80 may include a first support base 81 and a second support base 82. The first support base 81 may include a first support plate 811 and a second support plate 812, which are fixedly connected. The first support plate 811 and the second support plate 812 may be perpendicular or substantially perpendicular. The first support plate 811 is fixedly connected to the fixed base 30. The second support plate 812 may extend horizontally. In other words, the second support plate 812 is perpendicular or substantially perpendicular to the depth direction of the first feeding mechanism 10. The second support plate 812 has a first assembly notch 813 through which the push rod 55 passes. At least a portion of the second support plate 812 is located below and abuts against the first feeding mechanism 10 to support the first feeding mechanism 10. The second support plate 812 may restrict the downward movement of the first feeding mechanism 10. Furthermore, a guide groove 814 is formed on the surface of the second support plate 812 facing the first feeding mechanism 10. The guide groove 814 is arranged around the first assembly notch 813 circumferentially, and is adjacent to the first assembly notch 813. The guide groove 814 is open on one side facing the first assembly notch 813, thereby enabling communication between the guide groove 814 and the first assembly notch 813. The first feeding mechanism 10 can be assembled onto the second support plate 812 along the guide groove 814, and the first feeding mechanism 10 can also be moved out of the second support plate 812 along the guide groove 814. During the assembly and disassembly of the first feeding mechanism 10, the second support plate 812 can support the first feeding mechanism 10, thereby facilitating the assembly and disassembly of the first feeding mechanism 10. The sidewall of the guide groove 814 can restrict the movement of the first feeding mechanism 10.

[0139] As shown in Figure 4, the second support base 82 is located on the side of the first support plate 811 away from the fixed base 30. The second support base 82 may include a third support plate 821 and a fourth support plate 822, which are fixedly connected. The third support plate 821 and the fourth support plate 822 may be perpendicular or substantially perpendicular. The third support plate 821 is fixedly connected to the first support plate 811, and the fourth support plate 822 may extend in the horizontal direction. In other words, the fourth support plate 822 is perpendicular or substantially perpendicular to the depth direction of the first feeding mechanism 10. A second assembly notch 823 is formed at the end of the fourth support plate 822 away from the third support plate 821. The first feeding mechanism 10 can be assembled into the second assembly notch 823, thereby limiting the first feeding mechanism 10 by the fourth support plate 822. This can restrict the first feeding mechanism 10 from moving toward the fixed base 30, or allow the first feeding mechanism 10 to move radially along the second assembly notch 823.

[0140] In the above technical solution, the first feeding mechanism 10 is supported by a support base 80. The support base 80 can restrict the movement of the first feeding mechanism 10. During the assembly and disassembly of the first feeding mechanism 10, the second support plate 812 can support the first feeding mechanism 10, which makes it easier to assemble and disassemble the first feeding mechanism 10. Through the combined action of the support base 80 and the clamping structure, the stability of the position of the first feeding mechanism 10 is improved, and the first feeding mechanism 10 can be reliably fixed to the fixed base 30.

[0141] According to some embodiments of this application, the coating feeding device further includes: a waste box 90, and a second feeding mechanism 40 including a first valve body 41 and a discharge flow path 42. The first valve body 41 has a first valve body inlet 411, a first valve body outlet 412 and a first valve body discharge port 413. The first valve body inlet 411 is connected to the first feeding mechanism 10, the first valve body outlet 412 is connected to the discharge flow path 42, and the first valve body discharge port 413 is connected to the waste box 90. The first valve body inlet 411 is selectively connected to either the first valve body outlet 412 or the first valve body discharge port 413.

[0142] As shown in Figures 3 and 5, the coating feeding device may further include: a waste box 90, and the second feeding mechanism 40 may include a first valve body 41 and a discharge flow path 42. The first valve body 41 may be a three-way valve, and the first valve body 41 has a first valve body inlet 411, a first valve body outlet 412 and a first valve body discharge port 413. The first valve body inlet 411 may be connected to the material outlet 113 through a first pipeline, thereby connecting the first valve body inlet 411 and the first feeding mechanism 10. The first valve body outlet 412 may be connected to the discharge flow path 42 through a second pipeline, and the first valve body discharge port 413 may be connected to the waste box 90 through a third pipeline. The first valve body inlet 411 is selectively connected to either the first valve body outlet 412 or the first valve body discharge port 413. The first valve body inlet 411 can be connected to either the first valve body outlet 412 or the first valve body discharge port 413. The first valve body inlet 411 is selectively connected to either the first valve body outlet 412 or the first valve body discharge port 413.

[0143] Before coating the material to be coated, there may be gas above the material to be coated in the first feeding mechanism 10. At this time, the first valve body inlet 411 is connected to the first valve body outlet 413. The push rod 55 pushes the piston 12 to move towards the first end cover 117. The material to be coated in the first feeding mechanism 10 moves towards the first end cover 117 under the push of the piston 12, squeezing the gas in the first feeding mechanism 10 to the material outlet 113. The gas in the first feeding mechanism 10 flows into the waste box 90 through the first valve body inlet 411, the first valve body outlet 413, and the third pipeline in sequence. In addition, some of the material to be coated in the first feeding mechanism 10 can flow into the waste box 90, so that the first feeding mechanism 10 is filled with the material to be coated. At this time, the gas in the first feeding mechanism 10 is emptied, achieving the good working state required for coating, realizing the effect of venting the gas in the first feeding mechanism 10, and reducing the risk of the coating feeding device mixing gas into the material to be coated during the feeding process. After the gas is exhausted in the first feeding mechanism 10, the first valve body inlet 411 is connected to the first valve body outlet 412. The push rod 55 pushes the piston 12 to move toward the first end cover 117, so that the material to be coated fills the outlet flow path 42. By moving the material to be coated in the outlet flow path 42, the gas in the outlet flow path 42 is discharged from the coating mechanism, which further reduces the risk of the material to be coated being mixed with gas during the feeding process of the coating feeding device, and helps to achieve the effect of not mixing gas into the material to be coated during the entire feeding process.

[0144] In the above technical solution, by setting up a waste box 90, a first valve body 41 and a discharge flow path 42, the gas in the first feeding mechanism 10 can be discharged into the waste box 90, reducing the risk of the coating feeding device mixing gas into the material to be coated during the feeding process, and helping to achieve the effect that the material to be coated is not mixed with gas during the entire feeding process.

[0145] According to some embodiments of this application, as shown in Figures 3 and 5, there are multiple first feeding mechanisms 10 and multiple first valve bodies 41, and the multiple first feeding mechanisms 10 and multiple first valve bodies 41 are connected in a one-to-one correspondence, and the first valve body discharge port 413 of the multiple first valve bodies 41 are all connected to the waste box 90.

[0146] In this application, there are multiple first feeding mechanisms 10 and multiple first valve bodies 41. The number of first feeding mechanisms 10 and the number of first valve bodies 41 can be the same. Multiple first feeding mechanisms 10 and multiple first valve bodies 41 are connected in a one-to-one correspondence. That is, one first feeding mechanism 10 is connected to one first valve body 41. The number of first feeding mechanisms 10 and first valve bodies 41 can be two, three, four, five, etc. This application uses two first feeding mechanisms 10 as an example for illustration. The first valve body discharge ports 413 of the multiple first valve bodies 41 are all connected to the waste box 90. This can also be understood as the waste box 90 being connected to the first valve body discharge port 413 of each first valve body 41. The first valve body outlet ports 412 of the multiple first valve bodies 41 are all connected to the discharge flow path 42. In some examples, there can be multiple drive mechanisms 50, and multiple drive mechanisms 50 are assembled in a one-to-one correspondence with multiple first feeding mechanisms 10.

[0147] It should be noted that the prepared coating material can be packaged into multiple first feeding mechanisms 10, and multiple first feeding mechanisms 10 can be simultaneously placed into the vacuum chamber 21 to evacuate the coating material in batches. Furthermore, multiple fixing grooves can be formed in the vacuum chamber 21, and the shape of the fixing grooves can be adapted to the shape of the first feeding mechanism 10. One first feeding mechanism 10 can be placed in each fixing groove, reducing the risk of the first feeding mechanism 10 shaking in the vacuum chamber 21.

[0148] In the above technical solution, by setting multiple first feeding mechanisms 10 and multiple first valve bodies 41, and connecting the multiple first feeding mechanisms 10 and multiple first valve bodies 41 one-to-one, during the coating process, it is possible to select a single first feeding mechanism 10 to feed material, or to select multiple first feeding mechanisms 10 to feed material simultaneously. This allows for flexible control of the amount of material to be coated, thereby improving the utilization rate of the material to be coated. It can meet the needs of small-batch prototyping for flexible use of the amount of material to be coated, and also meet the needs of different products for changing the type of material to be coated.

[0149] According to some embodiments of this application, as shown in FIG1, the discharge flow path 42 includes: a second valve body 421 and a discharge pipe 422. The second valve body 421 has a second valve body discharge port 4211 and a plurality of second valve body inlets 4212. The second valve body discharge port 4211 is connected to the discharge pipe 422, and the plurality of second valve body inlets 4212 are respectively connected to the first valve body discharge ports 412 of a plurality of first valve bodies 41.

[0150] As shown in Figure 1, the discharge flow path 42 includes a second valve body 421 and a discharge pipe 422. The second valve body 421 has a second valve body discharge port 4211 and multiple second valve body inlets 4212. The second valve body discharge port 4211 can be connected to the inlet of the discharge pipe 422 through a fourth pipe, and the outlet of the discharge pipe 422 is connected to the coating mechanism, so that the material to be coated can move to the coating mechanism. The multiple second valve body inlets 4212 are connected one-to-one with the multiple first valve body discharge ports 412 of the multiple first valve bodies 41. By adjusting the second valve body 421, the second valve body discharge port 4211 can be connected to at least one second valve body inlet 4212, thereby improving the material supply effect of at least one first feeding mechanism 10. The number of first feeding mechanisms 10 participating in the material supply can be adjusted according to the actual coating needs, which is beneficial to improving the versatility of the coating feeding device. During the feeding process, the discharge port 4211 of the second valve body is connected to at least one inlet port 4212 of the second valve body, and the material to be coated that moves out of the first valve body 41 moves to the coating mechanism through the second valve body 421 and the discharge pipe 422 in sequence.

[0151] In the above technical solution, by setting a second valve body 421 and a discharge pipe 422, the discharge port 4211 of the second valve body can be connected to at least one second valve body inlet 4212, so that the feeding effect of at least one first feeding mechanism 10 can be adjusted according to the actual coating needs to allow different numbers of first feeding mechanisms 10 to participate in feeding, which is beneficial to improving the versatility of the coating feeding device.

[0152] Both the first valve body 41 and the second valve body 421 can be solenoid valves, and the operation of the first valve body 41 and the second valve body 421 can be automatically controlled by software.

[0153] According to some embodiments of this application, as shown in FIG1, the coating feeding device further includes: a flow detection mechanism 91, which is disposed on the fixed base 30 and cooperates with the discharge flow path 42 to detect the flow rate of the material to be coated in the discharge flow path 42.

[0154] The flow detection mechanism 91 can be a flow meter, which can be fixed to the mounting base 30 by bolts or snap-fit. The flow detection mechanism 91 works in conjunction with the discharge flow path 42 to detect the flow rate of the material to be coated within the discharge flow path 42, enabling real-time measurement of the material flow rate. The flow detection mechanism 91 can communicate with the MES (Manufacturing Execution System), and the flow information detected by the flow detection mechanism 91 can be stored in the MES system.

[0155] In the above technical solution, by setting a flow detection mechanism 91, the amount of material to be coated can be monitored and stored in real time during the coating process. The flow detection mechanism 91 is bound to the MES system. When the flow rate of the material to be coated deviates, the MES system can control the alarm device to promptly sound an alarm, reducing the risk of defective products in batches. Furthermore, the flow detection mechanism 91 can control the coating amount. In addition, the coating amount can also be controlled by controlling the pressure of the push rod 55 and the coating time. The flow meter's monitoring accuracy can reach 0.1g, and it can promptly feed back to the MES system for PID closed-loop control when deviations occur. PID (Proportional-Integral-Derivative) control is a widely used engineering control technology. It adjusts the system error through proportional, integral, and derivative control methods to achieve precise control. Its controller parameters can be tuned through theoretical calculations or engineering experience. It has the characteristics of simple structure, good stability, and convenient adjustment, and is widely used in the field of industrial automation.

[0156] It should be noted that the push rod 55 does not contact the material to be coated. The main parts to be cleaned are the first feeding mechanism 10 and the entire feeding pipeline structure, making cleaning convenient. When the coating feeding device needs cleaning, unscrew the first end cap 117 of the first feeding mechanism 10, pour in a certain amount of cleaning agent, tighten the first end cap 117 of the first feeding mechanism 10, open the first valve body 41 and the second valve body 421, and start the drive mechanism 50 to allow the cleaning agent to flow through the entire second feeding mechanism 40 and finally be discharged through the coating mechanism, completing the cleaning of the entire second feeding mechanism 40. Repeating this process two to three times will complete the cleaning. After cleaning the second feeding mechanism 40, disassemble the first feeding mechanism 10, insert the material to be coated, and after vacuuming in the vacuum chamber 21, the first feeding mechanism 10 can be reinstalled, quickly completing the material change.

[0157] According to some embodiments of this application, this application also provides a coating device, including the coating feeding device in the above embodiments, which can quickly discharge the gas in the material to be coated and improve the gas discharge effect in the material to be coated, which is beneficial to make the material to be coated in the first feeding mechanism 10 reach a good usable state, effectively improve the utilization rate of the material to be coated, reduce the waste of the material to be coated, and thus improve the performance of the coating device.

The vacuum degree of the vacuum chamber 21 is adjustable, and the vacuuming time of the vacuum chamber 21 is adjustable. The driving mechanism 50 and the piston 12 are detachably connected.

[0159] The main body 11 of the first feeding mechanism includes a barrel body 116, a first end cap 117 and a second end cap 118. The barrel body 116 is annular and open at both ends along the depth direction of the first feeding mechanism 10.

[0160] The coating feeding device further includes a clamping structure, a support base 80, and a waste container 90. The clamping structure is fixed to the fixed base 30 and is used to clamp or release the first feeding mechanism 10.

The second feeding mechanism 40 includes two first valve bodies 41 and a discharge flow path 42.
