Description

Technical Field

[0001] This application relates to the field of coating equipment technology, and in particular to a coating component and coating apparatus. Background Technology

[0002] Taking an air conditioner as an example, the circuit board inside an air conditioner is generally equipped with multiple high-power components. These components generate a lot of heat during operation, so heat sinks need to be installed on the components to dissipate heat. Thermal grease is applied between the components and the heat sink so that the heat generated by the components can be transferred to the heat sink for dissipation more efficiently.

[0003] Due to safety clearance limitations and the length of the device's pins, heat sinks are typically designed with multiple layers. Therefore, the thermal grease coating process in related technologies generally involves first setting up a multi-layered, contoured steel mesh on the heat sink, and then manually applying the thermal grease to the mesh. During application, the thermal grease is scraped from one side of the steel mesh to the other, repeating this process 3-4 times until the mesh openings are filled with thermal grease. As a result, the thermal grease coating process in related technologies is not only cumbersome and inefficient, but manual application also cannot guarantee a consistent film thickness of the thermal grease. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a coating component and coating apparatus that can improve film thickness consistency and coating efficiency.

[0005] To achieve the above objectives, one embodiment of this application provides a coating assembly, comprising:

[0006] The discharge head has a discharge port and a workpiece abutment surface, the workpiece abutment surface being located on one side of the discharge head along a first direction;

[0007] An elastic telescopic component, which extends and retracts to drive the discharge head to move along the first direction and / or deflect relative to the first direction.

[0008] In one embodiment, the discharge head has a coating channel communicating with the discharge port, the coating channel having a first coating port communicating with the outside, and the first coating port and the workpiece contact surface being located on the same side of the discharge head along the first direction.

[0009] In one embodiment, the coating channel is closed on one side along a second direction intersecting the first direction, and open on the opposite side to form a second coating port communicating with the outside.

[0010] In one embodiment, the workpiece contact surface is located on the side of the coating channel opposite to the second coating opening along the second direction.

[0011] In one embodiment, the discharge port is located on the side of the coating channel opposite to the first coating port along the first direction, and faces the first coating port; and / or,

[0012] The discharge head has a coating plane, which is located on the side of the coating channel opposite to the first coating port along the first direction.

[0013] In one embodiment, the number of elastic expansion members is multiple, and the multiple elastic expansion members are arranged at intervals.

[0014] In one embodiment, a plurality of the elastic telescopic members are respectively disposed on opposite sides of the discharge head along a third direction intersecting the first direction.

[0015] In one embodiment, the discharge head has a discharge channel communicating with the discharge port.

[0016] Another embodiment of this application provides a coating apparatus, including:

[0017] Displacement platform;

[0018] In the coating assembly described above, the discharge head is movably disposed on the displacement platform;

[0019] A conveying pipe, which is connected to the discharge port.

[0020] In one embodiment, the coating apparatus further includes a displacement detection device and a control device; the displacement detection device is used to detect the position information of the workpiece, and the control device controls the displacement platform to move according to the detection result of the displacement detection device, so that the workpiece contact surface contacts the workpiece.

[0021] In one embodiment, the coating apparatus further includes an identification device for identifying the type of the workpiece, and the control device delivers coating material corresponding to the workpiece to the delivery pipe according to the identification result of the identification device.

[0022] This application provides a coating assembly and a coating apparatus. The coating assembly includes a discharge head and an elastic telescopic member. During the coating process, the workpiece contact surface of the discharge head abuts against the workpiece. When the surface to be coated on the workpiece has a height error and / or tilts relative to the horizontal plane, the elastic telescopic member extends and retracts, causing the workpiece contact surface of the discharge head to move along a first direction and / or deflect at a certain angle relative to the first direction to achieve complete contact with the workpiece. This ensures that the distance between the coating nozzle and the surface to be coated on the workpiece remains consistent, thereby improving the consistency and uniformity of the coating thickness. Furthermore, compared to related technologies that involve setting a steel mesh before manual coating, the coating assembly in this application eliminates the need for a steel mesh, simplifying the coating steps and improving coating efficiency. Therefore, the coating assembly in this application not only improves film thickness consistency but also enhances coating efficiency. Attached Figure Description

[0027] In the description of the embodiments in this application, it should be noted that the term "first direction" refers to the direction based on the attached... Figure 1 and attached Figure 2 The directions or positional relationships shown, "second direction" is based on the attached... Figure 2 The orientation or positional relationship shown, "third direction" is based on the attached Figure 1 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0028] This application provides a coating component 11 (see example 11). Figures 1 to 2 The coating assembly 11 includes a discharge head 111 and an elastic telescopic member 112.

[0029] The discharge head 111 is used to apply the coating material 20 onto the workpiece 30. The coating material 20 includes, but is not limited to, thermal grease, heat dissipation silicone, and other materials with a certain degree of fluidity.

[0030] Figure 1 The workpiece 30 shown is a heat sink.

[0031] Please continue reading. Figure 2 The discharge head 111 has a discharge port 111a and a workpiece contact surface 111b, with the workpiece contact surface 111b located on one side of the discharge head 111 along a first direction. The elastic telescopic member 112 extends and retracts to drive the discharge head 111 to move along the first direction and / or deflect relative to the first direction.

[0032] The discharge port 111a is the outlet from which the coating material 20 flows out of the discharge head 111. In other words, the discharge head 111 discharges material through the discharge port 111a. The discharge direction of the discharge port 111a, that is, the depth direction of the discharge port 111a, can coincide with the first direction, or the discharge direction of the discharge port 111a can form an acute angle of less than 90° with the first direction.

[0033] The workpiece contact surface 111b is used to contact the workpiece 30. For example, the workpiece 30 has a region to be coated and a coating contact surface corresponding to the workpiece contact surface 111b. When the workpiece contact surface 111b contacts the coating contact surface, the coating material 20 coats the region to be coated on the workpiece 30 from the outlet 111a.

[0034] The elastic telescopic member 112 can only drive the discharge head 111 to move along the first direction without driving the discharge head 111 to deflect relative to the first direction, or the elastic telescopic member 112 can only drive the discharge head 111 to deflect relative to the first direction without driving the discharge head 111 to move along the first direction, or the elastic telescopic member 112 can not only drive the discharge head 111 to move along the first direction, but also drive the discharge head 111 to deflect relative to the first direction.

[0035] The elastic telescopic member 112 is used to adjust the position and / or deflection angle of the discharge head 111. When the workpiece contact surface 111b abuts against the workpiece 30, the discharge head 111, under the action of the reaction force, causes the elastic telescopic member 112 to extend or retract, thereby achieving displacement and / or deflection. When the workpiece contact surface 111b and the workpiece 30 move away from each other and no longer abut, the elastic telescopic member 112 returns to its original state, thereby driving the discharge head 111 back to its original state. That is to say, movement along the first direction means that the discharge head 111 moves relative to the workpiece 30 in the first direction. Deflection relative to the first direction means that the discharge head 111 deflects relative to its initial state during the process of abutting against the workpiece 30.

[0036] For example, when the height of the workpiece 30 deviates in the first direction, the elastic telescopic member 112 can adjust the position of the discharge head 111 in the first direction by telescopic adjustment, so that the workpiece contact surface 111b keeps in contact with the workpiece 30, thereby improving the consistency and uniformity of the coating thickness.

[0037] When the workpiece 30 is tilted relative to the workpiece contact surface 111b due to the processing error of the workpiece 30 or the unevenness of the processing table, the elastic telescopic member 112 can extend and retract to make the workpiece contact surface 111b of the discharge head 111 deflect at a certain angle relative to the first direction to achieve complete contact with the workpiece 30, thereby improving the consistency and uniformity of the coating thickness.

[0038] The type of elastic telescopic element 112 is not limited; for example, please refer to [link to relevant documentation]. Figure 1 The elastic telescopic component 112 can be a cylindrical spring. It is understood that the deformation mechanism of a cylindrical spring is not limited to uniform expansion and contraction along a single axial direction, but also has non-uniform deformation characteristics in a localized circumferential region. In other words, the cylindrical spring can achieve fine-tuning of the discharge head 111 in various directions through elastic deformation in a localized circumferential region. In another embodiment, the elastic telescopic component 112 can also be any other component capable of elastic expansion and contraction.

[0039] Another embodiment of this application provides a coating apparatus 10, please refer to... Figure 1 The coating apparatus 10 includes a coating component 11, a displacement platform 12, and a delivery pipe 13.

[0040] The discharge head 111 is movably disposed on the displacement platform 12. That is, the discharge head 111 is not fixed on the displacement platform 12, but can move and / or deflect relative to the displacement platform 12 in a first direction. For example, one end of the elastic telescopic member 112 along the telescopic direction (i.e., the first direction) is connected to the discharge head 111, and the other end is connected to the displacement platform 12, thereby driving the discharge head 111 to move and / or deflect relative to the displacement platform 12 in the first direction.

[0041] The displacement platform 12 can move the discharge head 111 relative to the workpiece 30. In other words, the discharge head 111 can be moved relative to the workpiece 30 through the displacement platform 12. This not only allows the discharge head 111 to coat the area to be coated on the workpiece 30, but also improves the coating accuracy by adjusting the relative position of the discharge head 111.

[0042] For example, the discharge head 111 can be moved in at least one of the X-axis, Y-axis, and Z-axis directions via the displacement platform 12. For instance, the displacement platform 12 may include a first displacement structure for moving the discharge head 111 in the Z-axis direction (i.e., vertical direction), thereby adjusting the distance between the discharge head 111 and the workpiece 30 in the Z-axis direction. The displacement platform 12 may include a second displacement structure for moving the discharge head 111 in the X-axis direction (i.e., horizontal direction), thereby adjusting the relative position of the discharge port 111a and the area to be coated, aligning the discharge port 111a with the area to be coated, and also allowing the discharge head 111 to move during the coating process. The displacement platform 12 may include a third displacement mechanism for moving the discharge head 111 in the Y-axis direction (i.e., longitudinal direction).

[0043] Please see Figure 1 The conveying pipe 13 is connected to the discharge port 111a. The conveying pipe 13 is used to convey the coating material 20 from the container (not shown) to the discharge head 111. Figure 2 The discharge head 111 shown has a discharge channel 111e that communicates with the discharge port 111a. The conveying pipe 13 can communicate with the discharge channel 111e. The coating material 20 flows through the conveying pipe 13 to the discharge channel 111e, and then coats the workpiece 30 from the discharge port 111a.

[0044] Understandably, after coating is completed, the air pressure inside the delivery pipe 13 can be controlled to prevent the coating material from overflowing from the outlet 111a and thus contaminating other areas of the workpiece.

[0045] The coating assembly 11 in this embodiment includes a discharge head 111 and an elastic telescopic member 112. During the coating process, the workpiece contact surface 111b of the discharge head 111 abuts against the workpiece 30. When the surface to be coated on the workpiece 30 has a height error and / or tilts relative to the horizontal plane, the elastic telescopic member 112 extends and retracts, causing the workpiece contact surface 111b of the discharge head 111 to move along a first direction and / or deflect at a certain angle relative to the first direction to achieve complete contact with the workpiece 30. This ensures that the distance between the coating nozzle and the surface to be coated on the workpiece 30 remains consistent, thereby improving the consistency and uniformity of the coating thickness. Furthermore, compared to the related technologies that involve setting a steel mesh and then manually coating, the coating assembly 11 in this embodiment eliminates the need for a steel mesh, simplifying the coating process and improving coating efficiency. Therefore, the coating assembly in this embodiment not only improves film thickness consistency but also enhances coating efficiency.

[0046] In one embodiment, please refer to Figure 2The discharge head 111 may have a coating channel 111c that communicates with the discharge port 111a. The coating channel 111c has a first coating port 111c1 that communicates with the outside. The first coating port 111c1 and the workpiece contact surface 111b are located on the same side of the discharge head 111 along the first direction.

[0047] When the workpiece contact surface 111b contacts the workpiece 30, the first coating port 111c1 is aligned with the area to be coated on the workpiece 30, and the coating material 20 is coated onto the surface of the workpiece 30 through the first coating port 111c1.

[0048] The coating channel 111c is used to shape the coating material 20. That is, the coating channel 111c determines the shape of the coating, which includes, but is not limited to, the thickness, width, and length of the coating. By setting different shapes of coating channels 111c and first coating openings 111c1, different coating shape requirements can be achieved.

[0049] For example, please refer to Figure 2 The coating channel 111c can penetrate the discharge head 111 along a third direction intersecting the first direction. By moving the discharge head 111 along the third direction during the coating process, the discharge head 111 can coat the workpiece 30 in the third direction. Preferably, the third direction can be perpendicular to the first direction. In another embodiment, the coating channel 111c can also be open at one end and closed at the other end along the third direction, or it can be closed at both opposite ends along the third direction.

[0050] Please continue reading. Figure 2 The coating channel 111c is closed on one side along a second direction intersecting the first direction, and open on the opposite side to form a second coating port 111c2 communicating with the outside. That is, the discharge head 111 can coat the workpiece 30 in the second direction by moving along the second direction. More preferably, the second direction can be perpendicular to both the first and third directions.

[0051] Please continue reading. Figure 2 The first coating port 111c1 and the second coating port 111c2 can be connected and are located on adjacent sides of the coating channel 111c respectively.

[0052] Please continue reading. Figure 2 The workpiece contact surface 111b can be located on the side of the coating channel 111c opposite to the second coating port 111c2 along the second direction, which can facilitate the discharge of the coating material 20 from the second coating port 111c2.

[0053] In one embodiment, please refer to Figure 2The discharge port 111a is located on the side of the coating channel 111c opposite to the first coating port 111c1 along the first direction and faces the first coating port 111c1, thereby quickly guiding the coating material 20 to the first coating port 111c1 for coating.

[0054] Please see Figure 2 The discharge head 111 may have a coating plane 111d, which is located on the side of the coating channel 111c opposite to the first coating port 111c1 along the first direction.

[0055] The coating plane 111d is used to limit the thickness of the coating material 20, and at the same time, it can keep the surface of the coating material 20 flat, so that the surface of the coating material 20 can have good flatness even when the roughness of the area to be coated is high.

[0056] It is understandable that the thickness of the coating material 20 on the workpiece 30 depends on the distance between the coating plane 111d and the surface of the workpiece 30, that is, the straight-line distance H between the coating plane 111d and the first coating port 111c1. By changing the straight-line distance H between the coating plane 111d and the first coating port 111c1, different coating thicknesses can be achieved.

[0057] For example, the heat dissipation material thickness of the heat sink on the circuit board is generally required to be around 0.2mm, so the straight-line distance H between the coating plane 111d and the first coating port 111c1 is 0.2mm.

[0058] In one embodiment, please refer to Figure 1 The number of elastic telescopic components 112 is multiple, and the multiple elastic telescopic components 112 are arranged at intervals. The multiple elastic telescopic components 112 cooperate with each other to achieve self-balancing compensation, thereby further improving the deflection flexibility and stability of the discharge head 111.

[0059] Please continue reading. Figure 1 Multiple elastic telescopic components 112 can be respectively arranged on opposite sides of the discharge head 111 along a third direction intersecting with the first direction, thereby improving the deflection flexibility and stability of the discharge head 111 in the third direction.

[0060] In another embodiment, a plurality of elastic telescopic members 112 may also be arranged on opposite sides of the discharge head 111 in other directions.

[0061] In one embodiment, please refer to Figure 1 The coating assembly 11 includes a support member 113 disposed on the discharge head 111, and an elastic telescopic member 112 disposed on the support member 113. That is, the elastic telescopic member 112 drives the discharge head 111 to move by driving the support member 113.

[0062] For example, the support member 113 is fixedly connected to the discharge head 111 to ensure the stability of the discharge head 111.

[0063] In the coating apparatus 10, one end of the elastic telescopic member 112 along the telescopic direction (i.e., the first direction) is connected to the displacement platform 12, and the other end is connected to the support member 113, thereby enabling the discharge head 111 to move relative to the displacement platform 12.

[0064] More preferably, the coating assembly 11 further includes a mounting post disposed on the elastic telescopic member 112, the mounting post being used to enhance the telescopic stability of the elastic telescopic member 112. In embodiments where the elastic telescopic member 112 is a cylindrical spring, the mounting post can be disposed within the cylindrical spring to prevent lateral buckling and / or instability during elastic telescopic deformation.

[0065] In one embodiment, the coating apparatus 10 may further include a displacement detection device and a control device. The displacement detection device is used to detect the position information of the workpiece 30, and the control device controls the displacement platform 12 to move according to the detection result of the displacement detection device, so that the workpiece contact surface 111b contacts the workpiece 30.

[0066] When the displacement detection device detects that the workpiece 30 has reached the set position, the control device controls the displacement platform 12 to move the discharge head 111 to the corresponding position, so that the workpiece contact surface 111b of the discharge head 111 contacts the workpiece 30, and the discharge port 111a is aligned with the area to be coated. During the coating process, the control device can control the displacement platform 12 to move according to a preset program, so that the discharge head 111 can coat different areas.

[0067] The type of displacement detection device is not limited; for example, the displacement detection device can be a displacement sensor.

[0068] In one embodiment, the coating apparatus 10 may further include an identification device for identifying the type of workpiece 30, and the control device for conveying coating material 20 corresponding to workpiece 30 to the delivery pipe 13 according to the identification result of the identification device.

[0069] In other words, the coating device 10 can coat different types of workpieces 30 with different coating materials 20 as needed to adapt to the diverse needs of the production line.

[0070] The identification device can be a barcode scanner. Different types of workpieces 30 correspond to different identification barcodes. The control device identifies the type of workpiece 30 through the barcode scanner and switches to the corresponding coating material 20 based on the type of workpiece 30, thereby ensuring the continuity, efficiency and stability of the entire production process.
