Technical Field
[0001] This application relates to the field of batteries, and more specifically, to a coating apparatus. Background Technology
[0002] Batteries are widely used in the new energy field, such as electric vehicles and new energy vehicles, which have become a new trend in the automotive industry. During battery production, it is often necessary to coat the surface of the workpiece with a coating; however, current coating equipment struggles to distribute the coating onto the workpiece surface in a specific shape and arrangement. Summary of the Invention
[0003] The purpose of this application is to provide a coating apparatus that aims to improve the problem in the related art of distributing coatings on the surface of a workpiece in a specific shape and arrangement.
[0004] This application provides a coating device, which includes a coating seat and a scraper groove for holding coating material. The scraper groove has a hollow area on its bottom wall for discharging the coating material.
[0005] In the above technical solution, when using the coating device, the bottom wall of the coating seat, facing away from the scraper groove, is held against the surface of the workpiece to be coated. Then, the coating material in the scraper groove is discharged from the stencil area, so that the coating material is applied to the workpiece. The stencil area can be set with a specific shape and arrangement so that the coating material is distributed on the surface of the workpiece according to a specific shape and arrangement.
[0006] As an optional technical solution in this application embodiment, the coating seat includes a frame and a material stop. Along the first direction, the frame has two opposing openings. The material stop covers an opening at the bottom of the frame along the first direction. The frame and the material stop together form the scraping groove. The hollow area is disposed on the material stop.
[0007] In the above technical solution, the scraping groove is formed by the frame and the material stop, and the hollow area is set in the material stop. The structure is simple and the manufacturing cost is low.
[0008] As an optional technical solution in this application embodiment, the baffle is detachably connected to the frame.
[0009] In the above technical solution, the material stop is detachably connected to the frame, facilitating cleaning and maintenance of both the material stop and the frame. Furthermore, if the material stop is damaged, it can be replaced for repair.
[0010] As an optional technical solution in this application embodiment, the bottom of the frame is provided with a limiting part, the limiting part is provided with a slot, and the end of the stop member is provided with a snap-fit part, the snap-fit part being used to snap-fit with the slot.
[0011] In the above technical solution, by setting a slot on the limiting part and forming a snap-fit part on the stop part, the snap-fit part can engage with the slot to achieve a detachable connection between the stop part and the frame. The structure is simple and the connection is convenient.
[0012] As an optional technical solution in this application embodiment, the bottom of the frame is provided with two limiting parts, the two limiting parts are arranged opposite to each other, and the openings of the slots on the two limiting parts are arranged opposite to each other.
[0013] In the above technical solution, by setting two limiting parts, the two locking parts at both ends of the material stop are respectively locked in the slots of the two limiting parts, which makes the connection between the material stop and the frame more stable.
[0014] As an optional technical solution in this application embodiment, the two limiting parts are arranged opposite to each other along the second direction, and the slot extends along the third direction and passes through at least one end of the limiting part, and the first direction, the second direction and the third direction are perpendicular to each other.
[0015] In the above technical solution, since the slot passes through at least one end of the limiting part in the third direction, the blocking part can be inserted into the slot in the third direction when installing the blocking part, making the installation of the blocking part more convenient and quick.
[0016] As an optional technical solution in this application embodiment, the coating device includes a plurality of material blocking members, one of which covers an opening at the bottom of the frame along the first direction.
[0017] In the above technical solution, by setting multiple baffles, a suitable baffle can be selected to cover an opening at the bottom of the frame along the first direction during use.
[0018] As an optional technical solution in this application embodiment, the shapes of the hollow areas of the plurality of material stoppers are different; and / or the positions of the hollow areas of the plurality of material stoppers are different; and / or the thicknesses of the plurality of material stoppers are different.
[0019] In the above technical solution, the hollow areas of the multiple baffles have different shapes. By replacing different baffles, the coating can be distributed on the surface of the workpiece in different shapes. The hollow areas of the multiple baffles are located in different positions. By replacing different baffles, the coating can be distributed at different positions on the workpiece surface. When using this coating device, the side of the baffle away from the scraper groove can be held against the surface of the workpiece to be coated. The coating accumulates within the hollow area, and the thickness of the baffle determines the thickness of the coating. When the thicknesses of the multiple baffles are different, the thickness of the coating on the workpiece surface is also different. The coating thickness can also be changed by replacing baffles of different thicknesses.
[0020] As an optional technical solution in this application embodiment, the bottom of the frame is provided with a limiting part, the limiting part is provided with a plurality of slots arranged along a first direction, and the end of the material stop is provided with a snap-fit part, each slot being used to snap-fit with the snap-fit part of one of the material stop parts.
[0021] In the above technical solution, by setting multiple slots arranged along the first direction on the limiting part, the baffle can fit against the frame when changing baffles of different thicknesses, reducing the risk of material leakage due to gaps between the baffle and the frame.
[0022] As an optional technical solution in this application embodiment, along the first direction, the snap-fit portion is located at the middle position of the end of the stop member.
[0023] In the above technical solution, by setting the snap-fit part at the middle position of the end along the first direction, the force is optimized and the risk of damage to the material stop is reduced.
[0024] As an optional technical solution in this application embodiment, along the first direction, the surface of the limiting part away from the frame is the first surface, and the surface of the material stop away from the scraper groove is the second surface, and the first surface is further away from the frame than the second surface.
[0025] In the above technical solution, the coating device can support the workpiece through the support member during use. Since the limiting part extends beyond the second surface in the direction away from the frame, when the limiting part contacts the support member, the stop member can no longer move in the direction of the workpiece, thereby reducing the risk of the stop member excessively squeezing the workpiece.
[0026] As an optional technical solution in this application embodiment, a limiting part is provided at the bottom of the frame. Along the first direction, the surface of the limiting part away from the frame is a first surface, and the surface of the material stop away from the scraper groove is a second surface. The first surface is further away from the frame than the second surface.
[0027] In the above technical solution, the coating device can support the workpiece through the support member during use. Since the limiting part extends beyond the second surface in the direction away from the frame, when the limiting part contacts the support member, the stop member can no longer move in the direction of the workpiece, thereby reducing the risk of the stop member excessively squeezing the workpiece.
[0028] As an optional technical solution in this application embodiment, the hollow area includes a first hollow area, a second hollow area and a third hollow area connected in sequence, and the first hollow area and the third hollow area are arranged opposite to each other along a second direction; the second direction is perpendicular to the thickness direction of the bottom wall.
[0029] In the above technical solution, the first hollow area, the second hollow area and the third hollow area form a U-shape, so that after being coated by the coating device, the coating can be distributed on the surface of the workpiece in a U-shape.
[0030] As an optional technical solution in this application embodiment, the bottom wall is provided with two hollow areas, the two hollow areas are arranged along a third direction, the two hollow areas are symmetrically arranged, and the second direction, the third direction and the thickness direction are perpendicular to each other.
[0031] In the above technical solution, the two hollowed-out areas are arranged symmetrically along a third direction. Thus, after coating by the coating device, the coating material forms two symmetrical portions on the surface of the workpiece.
[0032] As an optional technical solution in this application embodiment, the coating device further includes a mesh body, which is disposed in the scraping groove, and the projection of a plurality of mesh holes of the mesh body is located in the hollow area along the thickness direction of the bottom wall.
[0033] In the above technical solution, the surface of the workpiece may be uneven. Without a mesh, the paint will spread evenly on the surface of the workpiece, and when the paint is squeezed, a large amount of paint will overflow. However, with a mesh, the paint will be discharged from the mesh holes and distributed in a dotted pattern on the surface of the workpiece, and the paint is less likely to overflow when squeezed.
[0034] As an optional technical solution in this application embodiment, the mesh body is attached to the bottom wall.
[0035] In the above technical solution, when there is a gap between the mesh and the bottom wall, the coating may deviate after passing through the mesh, causing it to drip onto the workpiece surface at a position different from the theoretical position. By making the mesh adhere to the bottom wall, the risk of coating deviation can be reduced. In addition, because the mesh adheres to the bottom wall, the depth of the scraper groove can be reduced, which helps to reduce the volume of the coating holder.
[0036] As an optional technical solution in this application embodiment, the coating device further includes a scraper, which is used to scrape the coating material in the scraper groove out of the hollow area from the scraper groove.
[0037] In the above technical solution, by setting up a scraper, the coating material in the scraper groove is easily scraped out from the hollow area, so that the coating material adheres to the surface of the workpiece. The scraper can increase the speed at which the coating material is discharged from the scraper groove, thereby improving the coating efficiency.
[0038] As an optional technical solution in this application embodiment, the coating device further includes a first driving mechanism, which is connected to the scraper and is used to drive the scraper to move within the scraper groove, wherein the moving direction of the scraper groove is perpendicular to the thickness direction of the bottom wall.
[0039] In the above technical solution, by setting a first driving mechanism to drive the scraper to move within the scraping groove, it is beneficial to improve the scraping accuracy and automation level.
[0040] As an optional technical solution in this application embodiment, the coating device further includes a feeding mechanism for supplying the coating material to the scraper trough.
[0041] In the above technical solution, by setting up a feeding mechanism to supply paint into the scraper trough, automatic feeding can be achieved, which is conducive to improving the degree of automation and reducing the intensity of manual labor. Attached Figure Description

With the continuous expansion of battery applications, market demand is also constantly increasing.
[0065] In the battery manufacturing process, it is often necessary to apply coatings to the surface of the workpiece. The inventors have discovered that in the existing technology, when coating a workpiece, the coating completely covers the surface to be coated, and it is more difficult to distribute the coating on the surface of the workpiece in a specific shape and arrangement.

[0067] In use, the coating device holds the bottom wall of the coating holder against the surface of the workpiece to be coated, away from the scraper trough. The coating material in the scraper trough is then discharged from the stencil area, thus applying the coating material to the workpiece. The stencil area can be configured with a specific shape and arrangement to distribute the coating material onto the workpiece surface in a specific shape and arrangement.
[0068] The technical solutions described in this application are applicable to distributing coatings onto the surface of a workpiece in a specific shape and arrangement. The workpiece can be a battery cell.
[0069] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a front structural schematic diagram of the coating apparatus 10 provided in some embodiments of this application. Figure 2 This is a reverse structural diagram of the coating apparatus 10 provided in some embodiments of this application. Figure 3 This is a schematic diagram illustrating the structure of a coating apparatus 10 and a workpiece 20 as provided in some embodiments of this application. Embodiments of this application provide a coating apparatus 10, which includes a coating seat 11. The coating seat 11 has a scraper groove for receiving coating material. The bottom wall of the scraper groove has a perforated area 1121 for discharging the coating material.
[0070] The scraper groove is used to hold the paint. The bottom wall of the scraper groove has a hollow area 1121, through which the paint can be discharged from the scraper groove.
[0071] The hollow area 1121 can be considered as being formed by opening a through hole in the bottom wall of the scraper groove. The shape, size and position of the hollow area 1121 can be set as needed so that the paint discharged from the hollow area 1121 can be distributed on the surface of the workpiece 20 in a specific shape and arrangement.
[0072] When in use, the coating apparatus 10 can hold the bottom wall of the coating seat 11 away from the scraper groove against the surface of the workpiece 20 to be coated, and then discharge the coating material in the scraper groove from the cutout area 1121, so that the coating material is applied to the workpiece 20. The cutout area 1121 can be set with a specific shape and arrangement so that the coating material is distributed on the surface of the workpiece 20 in a specific shape and arrangement.
[0073] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the coating holder 11 includes a frame 111 and a baffle 112. Along a first direction, the frame 111 has two opposing openings, and the baffle 112 covers one opening at the bottom of the frame 111 along the first direction. The frame 111 and the baffle 112 together form a scraping groove. A cutout area 1121 is disposed on the baffle 112.
[0074] Please refer to Figure 1 , Figure 2 and Figure 3 The first direction can be the Z direction as shown in the figure.
[0075] The frame 111 can be a circular frame or a square frame; this embodiment does not limit this. Optionally, the frame 111 can match the contour shape of the surface to be coated on the workpiece 20.
[0076] The frame 111 forms the peripheral wall of the scraper groove, and the baffle 112 covers an opening at the bottom of the frame 111 along the first direction, forming the bottom wall of the scraper groove.
[0077] The scraping groove is formed by the frame 111 and the baffle 112, and the hollow area 1121 is set in the baffle 112. The structure is simple and the manufacturing cost is low.
[0078] In some embodiments, the baffle 112 is plate-shaped so that the workpiece 20 is brought into contact with the baffle 112 so that the coating is distributed on the surface of the workpiece 20 in a specific shape and arrangement. In addition, when the workpiece 20 and the baffle 112 are brought into contact, the gap between the workpiece 20 and the baffle 112 is small, and the coating is not easy to leak from the gap.
[0079] In some embodiments, the baffle 112 is detachably connected to the frame 111.
[0080] The detachable connection between the baffle 112 and the frame 111 means that the baffle 112 and the frame 111 can be separated by disassembly or connected by assembly.
[0081] Detachable connections can be bolt connections, pin connections, snap-fit connections, etc.
[0082] By detachably connecting the baffle 112 to the frame 111, it is convenient to clean and maintain both the baffle 112 and the frame 111. In addition, if the baffle 112 is damaged, it can be replaced for repair.
[0083] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the baffle 112 provided in some embodiments of this application. Figure 5 This is a schematic diagram of the structure of the limiting part 113 provided in some embodiments of this application. In some embodiments, the bottom of the frame 111 is provided with the limiting part 113, and the limiting part 113 is provided with a slot 1131. The end of the stop member 112 is provided with a snap-fit part 1122, which is used to snap-fit with the slot 1131.
[0084] A limiting part 113 is provided at the bottom of the frame 111. A slot 1131 is provided on the limiting part 113. A retaining member 112 is provided with a snap-fit part 1122, which snaps into the slot 1131 to achieve a detachable connection between the retaining member 112 and the limiting part 113. Since the limiting part 113 is provided on the frame 111, it can be understood that the frame 111 is detachably connected to the retaining member 112 through the limiting part 113.
[0085] By providing a slot 1131 on the limiting part 113, a snap-fit part 1122 is formed on the stop part 112. The snap-fit part 1122 can snap-fit with the slot 1131 to achieve a detachable connection between the stop part 112 and the frame 111. The structure is simple and the connection is convenient.
[0086] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the bottom of the frame 111 is provided with two limiting parts 113, which are arranged opposite to each other. The openings of the slots 1131 on the two limiting parts 113 are arranged opposite to each other.
[0087] "The openings of the slots 1131 on the two limiting parts 113 are arranged opposite to each other" can also be understood as the openings of the slots 1131 on the two limiting parts 113 facing each other, that is, the opening of the slot 1131 of the first limiting part 113 faces the second limiting part 113, and the opening of the slot 1131 of the second limiting part 113 faces the first limiting part 113.
[0088] By setting two limiting parts 113, the two locking parts 1122 at both ends of the baffle 112 are respectively locked in the locking grooves 1131 of the two limiting parts 113, which makes the connection between the baffle 112 and the frame 111 more stable.
[0089] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the two limiting portions 113 are disposed opposite each other along the second direction, and the slot 1131 extends along the third direction and passes through at least one end of the limiting portion 113. The first direction, the second direction, and the third direction are perpendicular to each other.
[0090] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The second direction can be the X direction shown in the figure, and the third direction can be the Y direction shown in the figure.
[0091] In some embodiments, the slot 1131 extends along a third direction and passes through one end of the limiting portion 113. The slot 1131 forms an opening at one end along the third direction and is closed at the other end. The slots 1131 of the two limiting portions 113 have the same orientation along the third direction. In other words, the slots 1131 of the two limiting portions 113 have the same side along the third direction.
[0092] In other embodiments, the slot 1131 extends along a third direction and passes through both ends of the limiting portion 113.
[0093] In some other embodiments, a slot 1131 on one limiting part 113 extends along a third direction and passes through one end of the limiting part 113, and a slot 1131 on the other limiting part 113 extends along a third direction and passes through both ends of the limiting part 113.
[0094] Since the slot 1131 passes through at least one end of the limiting part 113 in a third direction, when installing the stop part 112, the stop part 112 can be inserted into the slot 1131 in a third direction, making the installation of the stop part 112 more convenient and quick.
[0095] In some embodiments, the coating apparatus 10 includes a plurality of baffles 112, one of which covers an opening at the bottom of the frame 111 along a first direction.
[0096] By setting multiple baffles 112, when in use, a suitable baffle 112 can be selected to cover an opening at the bottom of the frame 111 along the first direction.
[0097] In some embodiments, the shapes of the cutout areas 1121 of the plurality of baffles 112 are different. And / or the positions of the cutout areas 1121 of the plurality of baffles 112 are different. And / or the thicknesses of the plurality of baffles 112 are different.
[0098] The shapes of the hollow areas 1121 of the multiple baffles 112 can be different so that the coating can be distributed on the surface of the workpiece 20 in different shapes.
[0099] The positions of the hollow areas 1121 of the multiple baffles 112 can be different so that the coating can be distributed on the surface of the workpiece 20 in different arrangements.
[0100] The thickness of the multiple baffles 112 is different to control the thickness of the coating applied to the surface of the workpiece 20.
[0101] The multiple baffles 112 have different shapes for their cutout areas 1121. By replacing different baffles 112, the coating can be distributed on the surface of the workpiece 20 in different shapes. The positions of the cutout areas 1121 of the multiple baffles 112 are also different. By replacing different baffles 112, the coating can be distributed at different positions on the surface of the workpiece 20. When using this coating apparatus 10, the side of the baffle 112 facing away from the scraper groove can be held against the surface of the workpiece 20 to be coated. The coating accumulates within the cutout area 1121, and the thickness of the baffle 112 determines the thickness of the coating. When the thicknesses of the multiple baffles 112 are different, the coating thickness on the surface of the workpiece 20 is also different. The coating thickness can also be changed by replacing baffles 112 of different thicknesses.
[0102] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the bottom of the frame 111 is provided with a limiting part 113, and the limiting part 113 is provided with a plurality of slots 1131 arranged along a first direction. The end of the stop member 112 is provided with a snap-fit part 1122, and each slot 1131 is used to snap-fit with the snap-fit part 1122 of a stop member 112.
[0103] Each limiting part 113 is provided with multiple slots 1131, which are arranged along the first direction. One of the multiple slots 1131 engages with the engaging part 1122 of the stop member 112.
[0104] By providing multiple slots 1131 arranged along the first direction on the limiting part 113, the baffle 112 can fit against the frame 111 when changing baffles 112 of different thicknesses, reducing the risk of material leakage due to gaps between the baffle 112 and the frame 111.
[0105] Please refer to Figure 6 , Figure 6 This is a front view schematic diagram of a stop member 112 provided in some embodiments of this application. In some embodiments, along a first direction, the snap-fit portion 1122 is located at the middle position of the end of the stop member 112.
[0106] "The snap-fit portion 1122 is located at the middle position of the end of the stop member 112 along the first direction" can also be understood as: along the first direction, the stop member 112 has a second surface 1123 and a third surface 1124 that are arranged opposite to each other, and the distance between the snap-fit portion 1122 and the second surface 1123 and the distance between the snap-fit portion 1122 and the third surface 1124 are equal.
[0107] By positioning the snap-fit portion 1122 at the middle position of the end along the first direction, the stress distribution is optimized, reducing the risk of damage to the stop member 112.
[0108] Please refer to Figure 7 , Figure 7 This is a schematic diagram showing the connection between a thinner baffle 112 and a limiting portion 113 provided in some embodiments of this application. In some embodiments, when the thinner baffle 112 is connected to the limiting portion 113, since the baffle 112 needs to fit against the lower end of the frame 111, a slot 1131 that is closer to the frame 111 along the first direction can be selected.
[0109] Please refer to Figure 8 , Figure 8This is a schematic diagram showing the connection between a thicker baffle 112 and a limiting portion 113 provided in some embodiments of this application. In some embodiments, when the thicker baffle 112 is connected to the limiting portion 113, since the baffle 112 needs to fit against the lower end of the frame 111, a slot 1131 that is relatively far away from the frame 111 along the first direction can be selected.
[0110] Please refer to Figure 7 and Figure 8 In some embodiments, along the first direction, the surface of the limiting part 113 facing away from the frame 111 is the first surface 1132, and the surface of the material stop 112 facing away from the scraper groove is the second surface 1123. The first surface 1132 is further away from the frame 111 than the second surface 1123.
[0111] Along the first direction, the scraper 12 has a second surface 1123 and a third surface 1124 facing each other, wherein the second surface 1123 is away from the scraper groove and the third surface 1124 is towards the scraper groove. Along the first direction, the limiting portion 113 extends beyond the second surface 1123 in the direction from the frame 111 toward the stopper 112.
[0112] When the coating apparatus 10 is in use, the workpiece 20 can be supported by the support member. Since the limiting part 113 extends beyond the second surface 1123 in the direction away from the frame 111, when the limiting part 113 contacts the support member, the stop member 112 can no longer move in the direction of the workpiece 20, thereby reducing the risk of the stop member 112 excessively squeezing the workpiece 20.
[0113] Please refer to this again. Figure 4 In some embodiments, the cutout area 1121 includes a first cutout area 11211, a second cutout area 11212, and a third cutout area 11213 connected in sequence. The first cutout area 11211 and the third cutout area 11213 are arranged opposite to each other along a second direction. The second direction is perpendicular to the thickness direction of the bottom wall.
[0114] The second cutout area 11212 connects the first cutout area 11211 and the third cutout area 11213. The first cutout area 11211 is positioned opposite to the third cutout area 11213 along the second direction. The length of the first cutout area 11211 can be equal to or unequal to the length of the third cutout area 11213. The first cutout area 11211, the second cutout area 11212, and the third cutout area 11213 together define a U-shaped cutout.
[0115] The thickness direction of the bottom wall is also the first direction mentioned above.
[0116] The first hollow area 11211, the second hollow area 11212 and the third hollow area 11213 form a U-shape, so that after being coated by the coating device 10, the coating can be distributed on the surface of the workpiece 20 in a U-shape.
[0117] In some embodiments, the bottom wall has two hollow areas 1121, which are arranged along a third direction. The two hollow areas 1121 are symmetrically arranged. The second direction, the third direction, and the thickness direction are perpendicular to each other.
[0118] Two hollowed-out areas 1121 are spaced apart along a third direction. The two hollowed-out areas 1121 are symmetrically arranged about the central vertical plane of the bottom wall along a third direction. The hollowed-out areas 1121 are U-shaped, and the open ends of the two hollowed-out areas 1121 are opposite each other.
[0119] Two hollowed-out areas 1121 are arranged symmetrically along a third direction. Thus, after being coated by the coating device 10, the coating material forms two parts on the surface of the workpiece 20, and the two parts are arranged symmetrically.
[0120] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the structure of a coating apparatus 10 (including a scraper 12) provided in some embodiments of this application. In some embodiments, the coating apparatus 10 further includes a mesh body 115 disposed in a scraper groove. Along the thickness direction of the bottom wall, the projections of a plurality of mesh holes 1151 of the mesh body 115 are located within the hollow area 1121.
[0121] The mesh body 115 can be arranged parallel or approximately parallel to the bottom wall. The mesh body 115 has multiple mesh holes 1151. Along the thickness direction of the bottom wall, the projections of some mesh holes 1151 are located within the hollow area 1121, while the projections of other mesh holes 1151 are located outside the hollow area 1121.
[0122] In some embodiments, the mesh body 115 has a plurality of mesh holes 1151, and the projections of all the mesh holes 1151 are located within the hollow area 1121 along the thickness direction of the bottom wall.
[0123] The mesh body 115 can be a steel mesh or a mesh plate.
[0124] The surface of workpiece 20 may be uneven. Without the mesh 115, the paint will spread evenly on the surface of workpiece 20, and when the paint is squeezed, a lot of paint will overflow. However, with the mesh 115, the paint will be discharged from the mesh holes 1151 and distributed in a dotted pattern on the surface of workpiece 20. When the paint is squeezed, it is less likely to overflow.
[0125] In some embodiments, the mesh 115 is attached to the bottom wall.
[0126] When there is a gap between the mesh 115 and the bottom wall, the paint may deviate after passing through the mesh openings 1151, causing it to drip onto the surface of the workpiece 20 at a position different from the theoretical position. By making the mesh 115 adhere to the bottom wall, the risk of paint deviation can be reduced. In addition, because the mesh 115 is adhered to the bottom wall, the depth of the scraper groove can be reduced, which helps to reduce the volume of the coating holder 11.
[0127] Please refer to Figure 9 In some embodiments, the coating apparatus 10 further includes a scraper 12, which is used to scrape the coating material in the scraper groove from the hollow area 1121 out of the scraper groove.
[0128] The scraper 12 can be installed inside or outside the scraper groove, extending into the scraper groove during operation. When scraping is required, the scraper 12 moves relative to the scraper groove to discharge the paint in the scraper groove from the hollow area 1121.
[0129] The scraper 12 can be plate-shaped. Along a third direction, the dimensions of the scraper 12 can be matched with the dimensions of the scraper groove to improve scraping efficiency.
[0130] By incorporating the scraper component 12, the coating material in the scraper groove is easily scraped out from the hollow area 1121, allowing the coating material to adhere to the surface of the workpiece 20. The scraper component 12 can increase the speed at which the coating material is discharged from the scraper groove, thereby improving coating efficiency.
[0131] Please refer to Figure 10 , Figure 10 This is a schematic block diagram of a coating apparatus 10 provided in some embodiments of this application. In some embodiments, the coating apparatus 10 further includes a first driving mechanism 13, which is connected to a scraper 12 and is used to drive the scraper 12 to move within a scraper groove. The direction of movement of the scraper groove is perpendicular to the thickness direction of the bottom wall.
[0132] The first drive mechanism 13 may include a linear drive element, such as a linear electric cylinder, a linear pneumatic cylinder, or a linear hydraulic cylinder. The first drive mechanism 13 may also include a rotary drive element and a transmission mechanism. The rotary drive element outputs rotational motion, and the transmission mechanism converts the rotational motion into linear motion of the scraper 12. The rotary drive element may be an electric motor, an internal combustion engine, etc. The transmission mechanism may be a lead screw and nut mechanism, a crank-slider mechanism, etc.
[0133] By setting the first drive mechanism 13 to drive the scraper 12 to move within the scraper groove, it is beneficial to improve the accuracy and automation of scraping.
[0134] Please refer to Figure 11 , Figure 11This is a schematic block diagram of a coating apparatus 10 provided for other embodiments of this application. In some embodiments, the coating apparatus 10 further includes a feeding mechanism 14 for supplying coating material to a scraper trough.
[0135] By setting up a feeding mechanism 14 to supply paint into the scraper trough, automatic feeding can be achieved, which is conducive to improving the degree of automation and reducing the intensity of manual labor.
[0136] In some embodiments, the coating apparatus 10 further includes a second driving mechanism connected to the coating stand 11. The second driving mechanism is used to drive the coating stand 11 to move so that the coating stand 11 can move closer to or away from the workpiece 20.
[0137] According to some embodiments of this application, please refer to Figures 1-9 .
[0138] This application provides a coating apparatus 10, which includes a coating seat 11 with a scraper groove for holding coating material. The bottom wall of the scraper groove has a perforated area 1121 for discharging the coating material. In use, the coating apparatus 10 can be held against the surface of a workpiece 20 to be coated, with the side of the bottom wall of the coating seat 11 away from the scraper groove facing the surface. The coating material in the scraper groove is then discharged through the perforated area 1121, thus coating the workpiece 20. The perforated area 1121 can be configured with a specific shape and arrangement to distribute the coating material on the surface of the workpiece 20 according to this specific shape and arrangement.
[0139] The coating holder 11 includes a frame 111 and a stopper 112. Along a first direction, the frame 111 has two opposing openings. The stopper 112 covers one opening at the bottom of the frame 111 along the first direction, and the frame 111 and the stopper 112 together form a scraping groove. A cutout area 1121 is disposed on the stopper 112. The frame 111 and the stopper 112 together form the scraping groove, and the cutout area 1121 is disposed on the stopper 112, resulting in a simple structure and low manufacturing cost.
[0140] The material stop 112 is detachably connected to the frame 111. The coating apparatus 10 includes multiple material stopes 112, one of which selectively covers an opening at the bottom of the frame 111 along a first direction. The shapes of the cutout areas 1121 of the multiple material stopes 112 are different; and / or the positions of the cutout areas 1121 of the multiple material stopes 112 are different; and / or the thicknesses of the multiple material stopes 112 are different. Because the cutout areas 1121 of the multiple material stopes 112 are different, by changing different material stopes 112, the coating can be distributed on the surface of the workpiece 20 in different shapes. Because the cutout areas 1121 of the multiple material stopes 112 are different, by changing different material stopes 112, the coating can be distributed at different positions on the surface of the workpiece 20. When the coating apparatus 10 is in use, the side of the baffle 112 facing away from the scraper groove can be held against the surface of the workpiece 20 to be coated. The coating material is piled up within the hollow area 1121, and the thickness of the baffle 112 determines the thickness of the coating material. When the thicknesses of multiple baffles 112 are different, the thickness of the coating material on the surface of the workpiece 20 is also different. The coating thickness can also be changed by replacing baffles 112 of different thicknesses.
[0141] A limiting part 113 is provided at the bottom of the frame 111. Along the first direction, the surface of the limiting part 113 facing away from the frame 111 is a first surface 1132, and the surface of the stop member 112 facing away from the scraper groove is a second surface 1123. The first surface 1132 is further away from the frame 111 than the second surface 1123. When the coating apparatus 10 is in use, the workpiece 20 can be supported by the support member. Since the limiting part 113 extends beyond the second surface 1123 in the direction facing away from the frame 111, when the limiting part 113 contacts the support member, the stop member 112 can no longer move in the direction of the workpiece 20, thereby reducing the risk of the stop member 112 excessively squeezing the workpiece 20.
[0142] The coating apparatus 10 also includes a mesh 115, which is disposed within the scraper groove. Along the thickness direction of the bottom wall, the projections of the multiple mesh openings 1151 of the mesh 115 lie within the hollowed-out area 1121. The surface of the workpiece 20 may be uneven. Without the mesh 115, the coating would spread evenly on the surface of the workpiece 20, and a significant amount would overflow when the coating is squeezed. However, with the mesh 115, the coating is discharged from the mesh openings 1151, distributed in a dotted pattern on the surface of the workpiece 20, and is less likely to overflow when the coating is squeezed.
[0143] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
