Description

Technical Field

[0001] This invention relates to the field of keycap painting technology, and more particularly to a keycap painting carrier that can be connected to a substrate for positioning. Background Technology

[0002] When painting keycaps, the keycaps need to be mounted on a fixture simulating a keyboard for painting. Existing keycap painting fixtures include a base plate with a connecting plate structure. The connecting plate structure includes multiple connecting plates spliced ​​on the base plate, and the connecting plates have bosses for mounting keycaps. The fit between the existing keycap painting fixture and the base plate is not reliable, which can easily lead to failure of the fixture during processing. This is because the fixture needs to be clamped and fixed on the machine when painting. If the base plate and fixture are not firmly fixed, the fixture will deform during clamping and pressing, resulting in poor painting accuracy.

[0003] Therefore, there is an urgent need to propose a new technical solution to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art. This invention provides a keycap painting carrier that can be connected to a substrate for positioning. The technical solution adopted is as follows:

[0005] A keycap painting carrier that can be positioned and connected to a substrate includes a carrier plate having a first surface and a second surface. The first surface and the second surface are parallel to each other and arranged opposite to each other. A connector is provided on the second surface. One end of the connector is fixedly connected to the second surface of the carrier plate, and the other end extends toward the substrate. The substrate is in contact with the second surface of the carrier plate. A connecting seat that mates with the connector is provided on the substrate. The carrier plate and the substrate are positioned and connected by engaging the connector with the connecting seat.

[0006] Furthermore, in the above technical solution, the connector includes a column and a limiting protrusion connected to the column. One end of the column is fixedly connected to the second surface of the carrier plate, and the other end of the column is connected to the limiting protrusion. The cross-sectional area of ​​the limiting protrusion is larger than the cross-sectional area of ​​the column. The column and the limiting protrusion form a hook shape, and the connector engages with the connecting seat on the substrate through the limiting protrusion.

[0007] Furthermore, the connector on the substrate includes a limiting through hole, the shape of which is adapted to the connector, the limiting boss of the connector protrudes from the limiting through hole and overlaps the surface of the substrate, and the post of the connector is accommodated in the limiting through hole; the height of the post is substantially the same as the thickness of the substrate.

[0008] Furthermore, the limiting boss has a limiting surface, a portion of the plane on the limiting surface abuts against the end of the column, and another portion of the plane on the limiting surface abuts against the plane of the substrate away from the second plate surface. The plane where the limiting surface is located is substantially coincident with the plane where the substrate is located.

[0009] Furthermore, the limiting boss also has an installation curved surface, which includes a first side surface, a first curved surface, an intermediate connecting surface, a second curved surface, and a second side surface. The first side surface, the first curved surface, the intermediate connecting surface, the second curved surface, and the second side surface are sequentially connected to form the installation curved surface. One end of the first side surface is connected to one end of the limiting surface, and one end of the second side surface is connected to the other end of the limiting surface. The curvature direction of the curved surface is towards the limiting surface.

[0010] Furthermore, the column is a square prism, one side surface of which is in contact with the first side surface of the mounting surface of the limiting boss, and the side surface of the square prism and the first side surface are located in the same plane. One end of the first curved surface of the mounting surface is tangent to the first side surface, and the curvature direction of the first curved surface is towards the column. The other end of the first curved surface is tangent to the intermediate connecting surface. The intermediate connecting surface is a plane, and the plane is parallel to the limiting surface. The second curved surface is tangent to the intermediate connecting surface, and the curvature direction of the second curved surface is towards the column. The second side surface is tangent to the second curved surface. The second side surface extends outward at an angle from the end connected to the second curved surface. The other end of the second side surface is connected to one end of the limiting surface. The end of the second side surface connected to the second curved surface is closer to the central axis of the column than the end of the second side surface connected to the limiting surface.

[0011] Furthermore, the first curved surface and the second curved surface are symmetrically arranged at both ends of the intermediate connecting surface, and the axis of symmetry of the first curved surface and the second curved surface is the perpendicular bisector of the intermediate connecting surface; the width of the intermediate connecting surface is one-seventh of the width of the limiting surface.

[0012] Furthermore, the carrier plate includes several overlapping sub-carrier plates. Each sub-carrier plate is provided with a mounting boss for fixing keycaps. The carrier plate includes a first sub-carrier plate, a second sub-carrier plate, a third sub-carrier plate, a fourth sub-carrier plate, and a fifth sub-carrier plate. The first and second sub-carrier plates overlap horizontally, the fifth and fourth sub-carrier plates overlap horizontally, the first and fifth sub-carrier plates overlap vertically, the second and fourth sub-carrier plates overlap vertically, and the second and fourth sub-carrier plates overlap horizontally with the third sub-carrier plate, respectively. Each sub-carrier plate is provided with a connector. The connector is located around the sub-carrier plate and close to its edge. The hook formed by the post and the limiting boss on each connector is away from the center of the sub-carrier plate. The carrier plate is connected to the limiting through hole on the substrate through the connector.

[0013] Furthermore, the substrate is an elongated plate, and the elongated plate is provided with the limiting through hole. The position of the limiting through hole corresponds to the position of the connector on the carrier plate. The shape of the limiting through hole is the same as the shape of the limiting boss of the connector. The size of the limiting through hole is basically the same as the size of the limiting boss of the connector. The limiting boss passes through the limiting through hole, and the hook formed by the limiting boss and the column engages with the limiting through hole.

[0014] Furthermore, a baffle is provided around the edge of the substrate, and the baffle extends from the edge of the carrier plate in a direction away from the first surface of the carrier plate. The baffle and the second surface of the substrate form a receiving cavity, and the substrate is received in the receiving cavity.

[0015] Compared with the prior art, the second plate surface of the carrier plate of the present invention is provided with a connector. The connector is snapped to the limiting through hole of the substrate. The connector on the carrier plate limits and fixes the carrier plate and the substrate, ensuring the supporting role of the substrate on the overall carrier plate, making the substrate and the overall carrier plate more stable, further ensuring the overall stability of the carrier during painting, ensuring the painting accuracy, and improving the yield and processing efficiency.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] The essence of the present invention will be further explained below with reference to the accompanying drawings and embodiments.

[0037] Example:

[0038] See Figure 1-10 This invention provides a keycap painting carrier that can be positioned and connected to a substrate. The carrier includes a carrier plate 100, which has a first surface and a second surface. The first surface and the second surface are parallel to each other and arranged opposite to each other. A connector is provided on the second surface. One end of the connector is fixedly connected to the second surface of the carrier plate 100, and the other end extends toward a substrate 400. The substrate 400 is in contact with the second surface of the carrier plate 100. A connecting seat is provided on the substrate 400 to mate with the connector. The carrier plate 100 and the substrate 400 are positioned and connected by the connector engaging with the connecting seat. A three-dimensional structural diagram of the carrier and the substrate can be seen below. Figure 1-2 ,Depend on Figure 2 It can be seen that the carrier plate 100 of the carrier is snapped together with the base plate 400.

[0039] In one embodiment, see Figure 8-10 The connector of the present invention includes a column 110 and a limiting protrusion connected to the column 110. One end of the column 110 is fixedly connected to the second plate surface of the carrier plate 100, and the other end of the column 110 is connected to the limiting protrusion. The cross-sectional area of ​​the limiting protrusion is larger than the cross-sectional area of ​​the column 110. The column 110 and the limiting protrusion 120 form a hook shape. The connector is engaged with the connecting seat on the substrate 400 through the limiting protrusion 120.

[0040] In one embodiment, see Figure 3The connector on the substrate 400 of the present invention includes a limiting through hole 420. The shape of the limiting through hole 420 is adapted to the connector. The limiting boss 120 of the connector protrudes from the limiting through hole 420 and overlaps the surface of the substrate 400. The post 110 of the connector is accommodated in the limiting through hole 420. The height of the post 110 is basically the same as the thickness of the substrate 400. This design can ensure that the connector and the limiting through hole on the substrate fit more tightly and are not easy to loosen. Preferably, the height of the post 110 is slightly less than the thickness of the substrate 400.

[0041] In one embodiment, see Figure 2 and Figure 8-10 The limiting boss 120 of the present invention has a limiting surface 121. A portion of the plane on the limiting surface 121 abuts against the end of the column 110, and another portion of the plane on the limiting surface 121 abuts against the plane of the substrate 400 opposite to the second plate surface, thus forming the hook shape of the connector to achieve a snap-fit ​​connection between the substrate and the carrier plate. The plane of the limiting surface 121 is substantially coincident with the plane of the substrate 400. This is to take into account the height of the column. Due to processing accuracy issues, it is difficult to process the height of the column to be exactly the same as the thickness of the substrate. If the height of the column is slightly less than the thickness of the substrate, the snap-fit ​​connection will be tighter. In this case, the height of the column is slightly less than the thickness of the substrate, and the limiting surface may be slightly raised relative to the substrate plane, but this connection is tighter.

[0042] In one embodiment, see Figure 8-10The limiting boss 120 of the present invention also has an installation curved surface, which includes a first side surface 122, a first curved surface 123, an intermediate connecting surface 124, a second curved surface 125, and a second side surface 126. The first side surface 122, the first curved surface 123, the intermediate connecting surface 124, the second curved surface 125, and the second side surface 126 are sequentially connected to form the installation curved surface. One end of the first side surface 122 is connected to one end of the limiting surface 121, and one end of the second side surface 126 is connected to the other end of the limiting surface 121. The bending direction of the curved surface is towards the limiting surface 121. The column 110 is a square prism. One side surface of the square prism is in contact with the first side surface 122 of the mounting surface of the limiting boss 120, and this side surface of the square prism and the first side surface 122 are located in the same plane. One end of the first curved surface 123 of the mounting surface is tangent to the first side surface 122, and the bending direction of the first curved surface 123 is towards the column 110. The other end of the first curved surface 123 is tangent to the intermediate connecting surface 124. The intermediate connecting surface 124 is a plane, and this plane is parallel to the limiting surface 121. The curved surface 125 is tangent to the intermediate connecting surface 124. The bending direction of the second curved surface 125 faces the column 110. The second side surface 126 is tangent to the second curved surface 125. The second side surface 126 extends outward from the end connected to the second curved surface 125. The other end of the second side surface 126 is connected to one end of the limiting surface 121. The end of the second side surface 126 connected to the second curved surface 125 is closer to the central axis of the column 110 than the end of the second side surface 126 connected to the limiting surface 121. The connector is designed in this shape to form an installation curved surface for the limiting boss. This curved surface can assist in installation. When the connector is installed in the limiting through hole of the substrate, the top surface of the installation curved surface, i.e., the intermediate connecting surface, faces the limiting through hole. Under the pressure of manual pressing, the installation curved surface will slide into the limiting through hole, making it easier and less strenuous to install the limiting boss into the limiting through hole.

[0043] In one embodiment, see further. Figure 8-10 In this invention, the first curved surface 123 and the second curved surface 125 are symmetrically arranged at both ends of the intermediate connecting surface 124, and the axis of symmetry of the first curved surface 123 and the second curved surface 125 is the perpendicular bisector of the intermediate connecting surface 124; the width of the intermediate connecting surface 124 is one-seventh of the width of the limiting surface 121. This structural shape is also designed to facilitate installation, as the limiting boss can be installed in the limiting through hole using a clever technique.

[0044] In one embodiment, see further. Figure 3-4The carrier plate 100 of the present invention includes a plurality of overlapping sub-carrier plates. Each sub-carrier plate is provided with a mounting boss 200 for fixing keycaps. The carrier plate 100 includes a first sub-carrier plate 101, a second sub-carrier plate 102, a third sub-carrier plate 103, a fourth sub-carrier plate 104, and a fifth sub-carrier plate 105. The first sub-carrier plate 101 and the second sub-carrier plate 102 overlap horizontally, the fifth sub-carrier plate 105 and the fourth sub-carrier plate 104 overlap horizontally, and the first sub-carrier plate 101 and the fifth sub-carrier plate 105 overlap vertically. Next, the second sub-carrier plate 102 and the fourth sub-carrier plate 104 overlap vertically, and the second sub-carrier plate 102 and the fourth sub-carrier plate 104 overlap horizontally with the third sub-carrier plate 103 respectively. Each sub-carrier plate is provided with a connector, which is located around the perimeter of the sub-carrier plate and close to its edge. The hooks formed by the posts 110 and the limiting bosses 120 on each connector are away from the center of the sub-carrier plate. The carrier plate 100 is connected to the limiting through holes 420 on the substrate 400 through the connectors. The hooks formed by the posts 110 and the limiting bosses 120 on each connector being away from the center of the sub-carrier plate makes the mounting boss more secure and can withstand pressure in all directions. This prevents the connector from breaking or coming loose from the limiting through holes due to force deviation or unevenness, ensuring production safety.

[0045] In one embodiment, see further. Figure 3-4 The substrate 400 of the present invention is an elongated plate, and the elongated plate is provided with the limiting through hole 420. The position of the limiting through hole 420 corresponds to the position of the connector on the carrier plate 100. The shape of the limiting through hole 420 is the same as the shape of the limiting boss 120 of the connector. The size of the limiting through hole 420 is basically the same as the size of the limiting boss 120 of the connector. The limiting boss 120 passes through the limiting through hole 420, and the hook formed by the limiting boss 120 and the column 110 engages with the limiting through hole 420.

[0046] In one embodiment, see further. Figure 1 , 2 The substrate 400 of the present invention has a baffle 150 at its edge. The baffle extends from the edge of the carrier plate 100 in a direction away from the first plate surface of the carrier plate 100. The baffle 150 and the second plate surface of the substrate 400 form a receiving cavity, and the substrate 400 is received in the receiving cavity.

[0047] In one embodiment, see further. Figure 1-12The present invention provides a keycap painting carrier, wherein the carrier plate 100 includes several overlapping sub-carrier plates, each of the sub-carrier plates is provided with a mounting boss 200 for fixing keycaps, the mounting boss 200 is provided with a keycap mounting groove 210, the mounting boss 200 is connected to the keycap through the keycap mounting groove 210, and the keycap 300 is engaged with the mounting boss 200.

[0048] In one embodiment, see Figure 4 The carrier plate 100 of this invention can be divided into a first sub-carrier plate 101, a second sub-carrier plate 102, a third sub-carrier plate 103, a fourth sub-carrier plate 104, and a fifth sub-carrier plate 105. The first and second sub-carrier plates 101 and 102 overlap horizontally, the fifth and fourth sub-carrier plates 105 overlap horizontally, the first and fifth sub-carrier plates 101 and 105 overlap vertically, the second and fourth sub-carrier plates 102 overlap vertically, and the second and fourth sub-carrier plates 102 and 104 overlap horizontally with the third sub-carrier plate 103, respectively. A substrate is nested within the carrier plate formed by these five sub-carrier plates. Processing the multiple sub-carrier plates formed by disassembling the carrier plate individually improves the overall precision, offering a precision advantage compared to the original large-plate overall processing.

[0049] In one embodiment, the two sub-carrier plates of the present invention are overlapped. One of the sub-carrier plates has a protruding edge with a thickness less than the thickness of its sidewall. The other sub-carrier plate has a groove on its edge that mates with the protruding edge, with the protruding edge embedded in the groove, so that the surfaces of the two sub-carrier plates are substantially flush. This overlapping method effectively ensures the sealing of the carrier plate surfaces, preventing mist paint from seeping into the substrate on the back of the carrier plate through the joint gap between the two sub-carrier plates, thus ensuring the cleanliness of the substrate and extending its service life.

[0050] In one embodiment, see Figure 1The carrier plate 100 of the present invention has a paint baffle strip 130 on one side where the mounting boss 200 is provided. The paint baffle strip 130 is wrapped around the carrier plate 100. The portion of the carrier plate 100 located inside the paint baffle strip 130 forms a spraying area, and the portion of the carrier plate 100 located outside the paint baffle strip 130 forms a fixing area. The mounting boss 200 is located within the spraying area. The paint baffle strip 130, which wraps around the carrier plate 100, divides the carrier plate 100 into a painting area and a fixing area. When the spray nozzle of the painting equipment sprays paint onto the keycap 300 on the mounting boss 200, the atomized paint in the nozzle will not affect the fixing area. It will only spray paint in the painting area, while the fixing area can be fixed to the machine tool to ensure that the keycap painting carrier will not move during the painting process. The base plate nested inside the keycap painting carrier can also support the keycap painting carrier. This support can enable the keycap painting carrier to withstand the painting pressure during the painting process and ensure the accuracy of keycap painting.

[0051] In one embodiment, the height of the paint baffle strip 130 is lower than the height of the mounting boss 200. The function of the paint baffle strip is to prevent the mist paint sprayed by the painting equipment from reaching the fixed area of ​​the carrier plate. Therefore, it does not need to be too high; it only needs to be able to prevent the spread of the mist paint to meet production requirements.

[0052] In one embodiment, see further. Figure 1The paint-blocking strip 130 extends vertically from the surface of the carrier plate 100 in a direction away from the carrier plate 100. The paint-blocking strip 130 comprises four segments, which are arranged in a circle around the carrier plate 100, forming the painting area on the surface of the carrier plate 100. The four segments are either not connected, or they are connected end-to-end, or two or three adjacent segments are connected. Multiple stacking pillars 140 are provided within the fixing area of ​​the carrier plate 100, located near the edge of the carrier plate 100 and evenly distributed around its perimeter. The total height of the mounting boss 200 and the keycaps 300 mounted on the mounting boss 200 is less than the height of the stacking pillars 140. The number of stacking pillars 140 is greater than or equal to three. The fixing area of ​​the carrier plate 100 is further provided with multiple grooves, which are rectangular or semi-circular grooves recessed from the edge of the carrier plate 100 into the interior of the carrier plate 100. The fixing area of ​​the carrier plate 100 is also provided with disassembly protective plates 170 for contacting the disassembly table support when disassembling the carrier plate 100. The disassembly protective plates 170 are located at the four top corners of the carrier plate 100, and the surface of the disassembly protective plates 170 is basically flush with the surface of the carrier plate 100. The edge of the disassembly protective plates 170 is provided with a limiting groove 171, and the depth of the limiting groove 171 is less than the thickness of the carrier plate 100.

[0053] In one embodiment, see Figure 1In this invention, a plurality of stacking pillars 140 are provided in the fixing area of ​​the carrier plate 100. The stacking pillars 140 are close to the edge of the carrier plate 100 and are evenly distributed around the carrier plate 100. The total height of the mounting boss 200 and the keycaps mounted on the mounting boss 200 is less than the height of the stacking pillars 140. The stacking pillars 140 extend vertically from the surface of the carrier plate 100 in a direction away from the carrier plate 100. The stacking pillars 140 are elongated and are arranged around the surface of the carrier plate 100 in a circle. The mounting boss 200 is located inside the circle of stacking pillars 140. There are multiple stacking pillars 140, which are spaced apart on the surface of the carrier plate 100 and are arranged around the surface of the carrier plate 100 in a circle. The carrier plate 100 is a long strip plate. Four stacking pillars 140 are respectively arranged on each of the two long sides of the long strip plate, and the four stacking pillars 140 are evenly distributed along the long side direction of the long strip plate. Two stacking pillars 140 are respectively arranged on each of the two short sides of the long strip plate, and the two stacking pillars 140 are evenly distributed along the short side direction of the long strip plate. When multiple keycap painting carriers are stacked, the stacking pillars can support and separate the keycap painting carriers, ensuring that the keycaps installed on the mounting bosses will not rub against the bottom of another keycap painting carrier, or rather, will not rub against the bottom of the substrate nested within another keycap painting carrier. At this time, the top of the stacking pillars rests against the bottom of the substrate, providing a safe space for the mounting bosses on which the keycaps are installed.

[0054] In one embodiment, the number of stacking pillars 140 in this invention is greater than or equal to three. These stacking pillars serve as a support and divider on the carrier plate, thus requiring sufficient stability. Two or one stacking pillars may result in insufficient stability, while two large stacking pillars would occupy too much space. Therefore, this invention employs a scheme of multiple small stacking pillars, ensuring support stability while dispersing them to save space. The stacking pillars are positioned on the fixed area, near the edge of the carrier, and serve as support when the carriers are stacked, preventing contact between the upper and lower carriers. During stacking, the gap between adjacent carriers, specifically between the aluminum plate of the upper carrier and the support boss of the lower carrier, is greater than the height of the keycap, preventing contact wear on the keycaps of the stacked carriers.

[0055] In one embodiment, see Figure 1The carrier plate 100 of the present invention has a retaining edge 150 around its edge. The retaining edge 150 extends from the carrier plate 100 in a direction away from the mounting boss 200. The retaining edge 150 contains a substrate 400, and the height of the retaining edge 150 is greater than the thickness of the substrate 400. The retaining edge of the present invention forms a receiving groove on the back of the keycap painting carrier, which can accommodate the substrate. When multiple carriers are stacked, it can play a limiting role. When the keycap painting carrier is fixed on the machine, the substrate supports the keycap painting carrier, which can ensure that the plastic keycap painting carrier does not deform. Similarly, the retaining edge can also protect the substrate from wear and extend the service life of the substrate.

[0056] In one embodiment, see Figure 1 and Figure 5-7 The carrier plate 100 of the present invention is provided with a plurality of mounting bosses 200, which are arranged in multiple rows on the carrier plate 100. Each row includes a plurality of mounting bosses 200. Upper through-holes 160 are provided between two adjacent mounting bosses 200 in each row and between mounting bosses 200 in two adjacent rows. The substrate 400 is provided with lower through-holes 410 aligned with the upper through-holes 160. The shape of the paint hole 410 is consistent with that of the upper paint-through hole 160. The diameter of the lower paint-through hole 410 is larger than that of the upper paint-through hole 160. The upper paint-through hole 160 has a hole wall extending from the carrier plate 100 toward the substrate 400. The hole wall of the upper paint-through hole 160 is accommodated within the lower paint-through hole 410 on the substrate 400. The upper paint-through hole 160 and the lower paint-through hole 410 are connected through the hole wall to form a paint guiding channel. The upper paint-through hole of the present invention can guide excess mist paint away during painting. When painting the keycaps from above the front of the carrier, a negative pressure is set below the substrate. The upper paint-through hole can depressurize the sprayed paint, and the mist paint is sucked away by the negative pressure through the upper paint-through hole on the carrier plate, reducing mist paint rebound and improving the uniformity of keycap painting.

[0057] In one embodiment, the upper through-hole 160 includes one or more of the following: a circular hole, an oblong hole, and a rectangular hole. The upper through-hole 160 is an oblong hole, and a reinforcing plate is disposed on the hole wall. The centers of the two long sides of the oblong hole are connected by the reinforcing plate, which is located at the end of the upper through-hole 160 opposite to the mounting boss. The end of the upper through-hole 160 opposite to the mounting boss is substantially flush with the side of the substrate 400 opposite to the mounting boss. A gap exists between the hole wall of the lower through-hole 410 of the substrate 400 and the hole wall of the upper through-hole 160, the width of which ranges from 1mm to 2mm.

[0058] In one embodiment, see Figure 1 The present invention includes a disassembly protective plate 170 integrally formed on the carrier plate 100 for contacting the disassembly table support when disassembling the carrier plate 100. The disassembly protective plate 170 is located at the four corners of the carrier plate 100, and its surface is substantially flush with the surface of the carrier plate 100. A limiting groove 171 is formed around the edge of the disassembly protective plate 170, recessed downwards from the surface of the carrier plate 100 to form a groove. The depth of the limiting groove 171 is less than the thickness of the carrier plate 100. The width of the limiting groove 171 is 1 mm, and its outer diameter is 1 cm. The carrier plate 100 is a long strip, and a disassembly protective plate 170 is located at each of its four corners. The distance from the edge of the limiting groove 171 of the disassembly protective plate 170 to the edge of the carrier plate 100 ranges from 0.5 cm to 1 cm. When disassembling the keycap painting carrier, the carrier is placed on the four ejector pins of the machine with the base plate facing upwards. The four ejector pins correspond to the disassembly protective plates at the four corners of the carrier. An impact force is then applied from above the base plate, causing the ejector pins to penetrate the disassembly protective plates, and the carrier detaches from the base plate. During carrier disassembly, the disassembly protective plates provide support, preventing one corner of the base plate from being suspended in mid-air when disassembling a sub-carrier plate, thus preventing base plate deformation. This is because the downward disassembly pressure during the removal of connecting blocks can easily cause base plate deformation. When disassembling the carrier, the ejector pins press against the disassembly protective plates and cut them off, removing the carrier while protecting the base plate (preventing base plate deformation). Furthermore, the disassembly protective plates are integrally formed with the carrier on the base plate, without gaps, preventing paint leakage, and are located in the fixing area of ​​the base plate.

[0059] In one embodiment, see Figure 5-7 The mounting boss 200 of the present invention is provided with a keycap relief groove 220. The keycap relief groove 220 is centrally located on the upper surface of the mounting boss 200. The keycap relief groove 220 is recessed downward from the upper surface to form a groove. The keycap has a protrusion 310 that cooperates with the keycap relief groove 220. The keycap is positioned by cooperating with the keycap relief groove through the protrusion.

[0060] In one embodiment, see further. Figure 7The keycap clearance groove 220 includes a first clearance hole 221 and a second clearance groove 222 communicating with the first clearance hole 221. The first clearance hole 221 and the second clearance groove 222 are coaxially arranged, and the diameter of the first clearance hole 221 is larger than the inner diameter of the second clearance groove 222. One end of the first clearance hole 221 is flush with the upper surface of the mounting boss 200. That is, the first clearance hole and the second clearance groove form a stepped groove, which has a better limiting effect and improved positioning accuracy.

[0061] In one embodiment, the first clearance hole 221 is a through hole with a depth of not less than 1 mm and an inner diameter of 0.5-0.7 cm. The first clearance hole 221 communicates with the second clearance groove 222. The first clearance hole 221 has a first end and a second end opposite to the first end. The first end is flush with the upper surface of the mounting boss 200, and the second end is connected to the top of the second clearance groove 222. The inner diameter of the second clearance groove 222 is smaller than the diameter of the first clearance hole 221. The plane containing the top of the second clearance groove 222 coincides with the plane containing the end face of the second end of the first clearance hole 221. The second end of the first clearance hole 221 and the top of the second clearance groove 222 are connected by a carrier plate. The depth of the second clearance groove 222 is not less than 1 mm, and the inner diameter of the second clearance groove 222 is 0.6-0.4 cm.

[0062] In one embodiment, the depth of the keycap relief groove 220 is greater than or equal to 2mm. If the depth of the keycap relief groove is insufficient, the keycap may slide within the keycap relief groove. Therefore, its depth is also an important indicator for positioning and limiting.

[0063] In one embodiment, see Figure 1 , 3The carrier plate 100 of the present invention is further provided with a positioning post 180. The positioning post 180 includes a through hole formed on the carrier plate 100. The through hole has a hole wall extending from the carrier plate 100 in a first direction and a second direction simultaneously. The first direction is opposite to the second direction, and both the first direction and the second direction are perpendicular to the surface of the carrier plate 100. A cover plate 181 is provided at one end of the hole wall of the through hole. The cover plate 181 is located on the side of the carrier plate 100 where the mounting boss 200 is provided. The cover plate 181 has a central hole that communicates with the through hole. The hole wall of the through hole and the cover plate 181 form the positioning post 180 on the carrier plate 100. The positioning post passes through a main positioning hole on the substrate corresponding to the positioning post, and the main positioning hole is engaged with the periphery of the positioning post. During painting, the positioning post on the keycap painting carrier can be directly positioned by the pressure post on the automated machine, preventing the positioning rod from wearing down the aluminum plate and extending the service life of the aluminum plate.

[0064] In one embodiment, the installation height of the cover plate 181 is greater than the height of the mounting boss 200. This ensures the positioning accuracy of the pressure post on the machine when directly positioning the positioning post on the keycap painting carrier. Since the pressure post is inserted into the hole of the positioning post, if the hole is too shallow, the carrier may deflect during painting, resulting in insecure fixing. The cover plate has a central hole that communicates with the through hole, allowing the insertion of the pressure post to be observed through the central hole, further confirming proper installation and reducing the defect rate caused by improper installation.

[0065] In one embodiment, the end of the through-hole wall without the cover plate 181 penetrates the main positioning hole 430 on the substrate 400. The height of the end of the through-hole wall without the cover plate 181 is less than or equal to the thickness of the substrate 400. This ensures that the main positioning hole of the substrate is fitted around the positioning post hole wall, protecting the main positioning hole of the substrate from wear by the pressure post of the automated equipment.

[0066] In one embodiment, see further. Figure 3 The carrier plate 100 of the present invention is provided with at least two positioning posts 180, which are respectively disposed at both ends of the carrier plate 100. The two positioning posts can ensure the stability of the carrier. Since the positioning posts cooperate with the pressure posts of the automated equipment, the number of pressure posts of the automated equipment should also be considered. Furthermore, it is preferable that the two positioning posts are respectively disposed at both ends of the carrier plate, and the two positioning posts are not on the same horizontal line, that is, the two positioning posts are asymmetrical on both sides of the carrier plate.

[0067] In one embodiment, the positioning post 180 is a hollow column, and the wall of the through hole has an opening at one end in the first direction, the opening communicating with the through hole. The fixing post of the automated equipment is accommodated in the through hole through the opening. The main positioning hole 430 on the substrate 400 is located at the edge of the substrate 400, the inner diameter of the main positioning hole 430 is larger than the outer diameter of the wall of the through hole, and the end face of the main positioning hole 430 away from the mounting boss 200 is substantially flush with the end face of the wall of the through hole of the positioning post 180 in the second direction. At least two positioning posts 180 are provided on the carrier plate 100, and the two positioning posts 180 are respectively provided at both ends of the carrier plate 100. The two positioning posts 180 are diagonally distributed on the carrier plate 100.

[0068] In one embodiment, see Figure 5-7 The mounting boss 200 of the present invention is further provided with a plurality of upper reserved holes 230. The hole walls of the upper reserved holes 230 extend downward from the surface of the mounting boss 200 to penetrate the lower reserved holes 440 on the substrate 400. The hole walls of the upper reserved holes 230 are accommodated within the lower reserved holes 440. The diameter of the upper reserved holes 230 is smaller than the diameter of the lower reserved holes 440. The upper and lower reserved holes can be exposed to paint, and during painting, a negative pressure is formed under the carrier. The negative pressure can further fix the keycap to the mounting boss through the upper and lower reserved holes.

[0069] In one embodiment, see Figure 5-7 , Figure 12 The mounting boss 200 of the present invention is further provided with a keycap mounting groove 210. The keycap mounting groove 210 includes a side groove 211 and a surface groove 212. The keycap 300 and the mounting boss 200 are engaged and connected by the side groove 211 and the surface groove 212. The side groove 211 is formed on the surface of the mounting boss 200 and is formed along the side wall of the mounting boss 200. The height of the side wall that overlaps with the side wall of the mounting boss 200 is less than the height of the mounting boss 200. This height difference makes it easier to fix the keycap to the mounting boss, which is convenient for installation and disassembly. A concave hole is provided on this side wall. The concave hole cooperates with the reinforcement 3213 of the hook 321 on the keycap 300. The reinforcement 3213 of the hook 321 is engaged in the concave hole.

[0070] In one embodiment, see further. Figure 7The surface groove 212 of this invention is formed on the surface of the mounting boss 200. A retaining pin is provided on the groove wall of the surface groove 212. The mounting height of the retaining pin is lower than the upper surface of the mounting boss 200. The retaining pin and the retaining socket on the keycap are aligned and installed to ensure a fixed connection. The cooperation between the retaining pin and the retaining socket allows for a slight rotation angle, which is more reasonable and provides an error buffer. That is, rotation within the deviation angle does not affect the accuracy of the paint spraying, and the relatively rigid connection makes it less likely to damage the keycap. In addition, the retaining pin and retaining socket connection can prevent paint from flowing into the socket hole, preventing the keycap with paint in the socket hole from making abnormal noise when the keyboard is pressed, reducing the lifespan of the keyboard and affecting the user experience.

[0071] In one embodiment, see further. Figure 7 The mounting boss 200 of this invention is provided with two side grooves 211, two surface grooves 212, and three upper reserved holes 230. The three upper reserved holes 230 are arranged in a triangular pattern, and the side grooves 211 and surface grooves 212 are located around the three upper reserved holes 230. This design makes the surface utilization of the mounting boss higher, and the arrangement of the side grooves, surface grooves, and upper reserved holes can ensure the installation stability of the keycap and ensure the painting accuracy.

[0072] The present invention also provides a keycap fixed on a keycap painting carrier, see below. Figure 11-12 The keycap painting carrier of the present invention is provided with a mounting boss 200 for fixing the keycap 300. The mounting boss 200 is provided with a keycap mounting groove 210. The keycap 300 is provided with a snap-fit ​​structure 320 that cooperates with the keycap mounting groove 210. The keycap 300 is fixedly connected to the keycap painting carrier through the snap-fit ​​structure 320.

[0073] In one embodiment, the keycap mounting groove 210 provided by the mounting boss 200 includes a side groove 211 and a surface groove 212, and the keycap 300 is engaged with the side groove 211 and the surface groove 212 by a snap-fit ​​structure 320.

[0074] In one embodiment, the side groove 211 is formed on the surface of the mounting boss 200, and the side groove 211 is formed along the side wall of the mounting boss 200. The height of the side wall that coincides with the side wall of the mounting boss 200 is less than the height of the mounting boss 200. This height difference makes it easier for the keycap to be fixed and positioned with the mounting boss, which is convenient for installation and disassembly. In addition, a recessed hole is provided on this side wall. The recessed hole cooperates with the reinforcement 3213 of the hook 321 on the keycap 300. The reinforcement 3213 of the hook 321 is engaged in the recessed hole. The surface groove 212 is formed on the surface of the mounting boss 200. A retaining pin 213 is provided on the groove wall of the surface groove 212. The mounting height of the retaining pin 213 is lower than the upper surface of the mounting boss 200. The snap-fit ​​structure 320 of the keycap 300 includes a hook 321 that mates with the side groove 211 and a retaining seat 322 that mates with the surface groove 212. The alignment and installation of the retaining pin and the retaining seat on the keycap ensures a fixed connection. The fit between the retaining pin and the retaining seat allows for a slight rotation angle, which is a more reasonable design and provides error buffer. That is, rotation within the deviation angle does not affect the accuracy of the paint spraying. Moreover, the relatively rigid connection makes it less likely to damage the keycap. Furthermore, the retaining pin and retaining seat connection can prevent paint from flowing into the seat hole of the retaining seat. This prevents keycaps with paint in the seat hole from making abnormal noises when the keyboard is pressed, reducing the lifespan of the keyboard and affecting the user experience.

[0075] In one embodiment, the latch structure 320 has a reinforcing member 3213 on its hook 321, which is accommodated in a recessed hole on the side wall of the side groove 211. A retaining pin 213 is provided on the groove wall of the surface groove 212, and the keycap 300 is fixedly connected to the retaining pin 213 of the surface groove 212 via a retaining base 322. The reinforcing member is located on the side of the support column, connecting the support column to the edge of the keycap, thus increasing the strength of the latch and making it less prone to breakage. This structural design allows the support column and the top plate to form a latch that mates with the side groove of the mounting boss.

[0076] In one embodiment, the latch 321 includes a support post 3211 and a top plate 3212 connected to the support post 3211. One end of the support post 3211 is connected to the back of the keycap 300, and the other end is connected to the top plate 3212. The cross-sectional shape of the support post 3211 is "L" shaped, and the top plate 3212 is rectangular. The top plate 3212 covers the surface of the support plate. The reinforcing body 3213 is disposed on the side wall of the support post 3211. The latch seat 322 has a seat hole 3221 that mates with the latch shaft 213. The central axis direction of the seat hole 3221 is the same as the central axis direction of the latch shaft 213. The hole wall of the seat hole 3221 has an opening, and the latch shaft 213 is accommodated in the seat hole 3221 through the opening. The alignment and installation of the hinge with the keycap ensures a secure connection. The fit between the hinge and the keycap allows for slight rotation, which is a more reasonable design and provides an error buffer. This means that rotation within the deviation angle does not affect the accuracy of the paint spraying. Moreover, the relatively rigid connection makes it less likely to damage the keycap.

[0077] In one embodiment, the seat hole 3221 is a circular through hole, and the width of the opening on the wall of the seat hole 3221 is smaller than the diameter of the seat hole 3221; the cross-section of the retaining shaft 213 is a combination of a rectangle and a semicircle, and the diameter of the semicircle is larger than the side length of the rectangle. The rectangle and the semicircle are connected by a bevel. The rectangle is close to the bottom of the mounting boss 200, and the semicircle is close to the surface of the mounting boss 200. The retaining shaft 213 is received within the seat hole 3221 through the opening of the seat hole 3221, with the semicircular cross-section portion of the retaining shaft 213 also received within the seat hole 3221, and the rectangular cross-section portion of the retaining shaft 213 located at the opening of the seat hole 3221. In this invention, the diameter of the semicircular cross-section portion of the retaining shaft 213 is larger than the width of the opening on the wall of the seat hole 3221, and the retaining seat 322 of the keycap 300 is pressed onto the retaining shaft 213 through the opening of the seat hole 3221.

[0078] In one embodiment, a keycap relief groove 220 is centrally located on the upper surface of the mounting boss 200. The keycap relief groove 220 is recessed downwards from the upper surface to form a groove. The keycap 300 has a protrusion 310 that mates with the keycap relief groove 220. The keycap is positioned by engaging with the keycap relief groove through the protrusion. The depth of the keycap relief groove 220 can be greater than or equal to 2 mm. If the depth of the keycap relief groove is insufficient, the keycap may slip within the groove. Therefore, its depth is also an important indicator for positioning and limiting.

[0079] In one embodiment, the keycap clearance groove 220 is surrounded by upper reserved holes 230. There may be three upper reserved holes 230. The keycap clearance groove 220 is located at the center of the three upper reserved holes 230. The upper reserved holes 230 have hole walls extending from the surface of the mounting boss 200 toward the substrate. The upper reserved holes 230 can assist in paint penetration so that when the keycap is painted, the mist paint does not penetrate into the snap-fit ​​structure of the keycap, thus providing a protective function.

[0080] The carrier described in this invention is fixedly connected to the base plate via connectors, improving the stability of fixing several connecting blocks to the aluminum plate. The positioning post described in this invention passes through the main positioning hole corresponding to the positioning post on the aluminum plate, and the main positioning hole is positioned around the positioning post. It can be directly positioned on the painting carrier by a pressing post on an automated machine, preventing the positioning rod from wearing down the aluminum plate. The automated machine presses down on the fixing area of ​​the carrier, further securing it. These multiple fixing actions ensure the accuracy of painting when using the carrier.

[0081] In one embodiment, the method of spraying the keycaps using a spray painting device according to the present invention specifically includes: aligning the spray nozzle of the spray painting device with the side of the keycap spray painting carrier provided with the mounting boss; during spraying, a negative pressure is formed on the side of the keycap spray painting carrier where the substrate is mounted; the atomized paint not adhering to the keycaps is drawn out by the negative pressure through the paint-permeable holes on the top of the keycap spray painting carrier. This method can ensure the uniformity of the paint spraying and improve the product yield.

[0082] In one embodiment, the separation of the substrate 400 from the keycap painting carrier according to the present invention specifically includes: placing the keycap painting carrier with the substrate facing upward on four ejector pins of the machine, the four ejector pins respectively supporting the disassembly protective plates on the four corners of the keycap painting carrier, applying an impact force from above the substrate of the keycap painting carrier, the ejector pins penetrating the disassembly protective plates, and the keycap painting carrier detaching from the substrate.

[0083] The carrier described in this invention can be used three times in production applications. If it is used further, there may be a risk that the precision requirements will not be met. Therefore, in order to ensure that the processing precision of the product meets the requirements, the carrier should be replaced after it has been used three times, while the corresponding substrate does not need to be replaced. The substrate will be used until it no longer meets the processing requirements. Therefore, the substrate, as a durable product, is protected by the carrier in every way to extend its service life. This is not only for cost considerations, but also for the sustainable use of resources.
