DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0026] Embodiment 1: Referring to Figures 1 to 3 as shown, a keycap painting carrier assembly includes a keycap mounting boss 1. Positioning grooves 2 are respectively arranged at the four corners of the top of the keycap mounting boss 1, and a positioning member 3 is respectively arranged in each positioning groove 2;

[0027] Four top holes 4 are arranged on the top surface of the keycap mounting boss 1. The bottom of the top hole 4 is communicated with the bottom surface of the keycap mounting boss 1. The four top holes 4 are arranged on the keycap mounting boss 1 between the four positioning grooves 2, and each top hole 4 is respectively arranged close to a positioning groove 2.

[0028] In this embodiment, when the outer surface of the keycap needs to be painted, the keycap is directly sleeved on the keycap mounting boss. The outer wall of the keycap mounting boss matches the inner surface of the bottom of the keycap (or is slightly smaller than the inner surface of the keycap by a little dimension, so that the keycap can move up and down relative to the keycap mounting boss smoothly without scratching). The four positioning clips inside the keycap are respectively inserted into the four positioning slots. At the same time, each positioning clip of the keycap is respectively clamped with the positioning member of each positioning slot, and the keycap is limited by the positioning member, so that the keycap is stably limited on the keycap mounting boss. During subsequent painting, it can effectively prevent the keycap from shaking or other problems relative to the keycap mounting boss, ensure that the topcoat on the outer surface of the keycap is flat and has a consistent uniformity during painting, and there will be no problem that the painting thickness is thicker at a certain position and thinner at a certain position, thus ensuring the painting quality. At the same time, multiple ejector rods will be arranged on the subsequent keycap disassembly device. Each ejector rod is arranged opposite to the ejector hole. When the painting is completed, the painting carrier with the keycap will be above the ejector rod, and then the ejector rod extends. Each keycap is lifted upward by the four ejector rods at the same time to separate the keycap from the keycap mounting boss. In this process, the force on the keycap is more uniform. At the same time, since the keycap and the keycap mounting boss are mainly clamped and limited by the four positioning members, each ejector hole is arranged beside a positioning slot. In this way, the upward lifting force applied by each ejector rod to the keycap to separate it from the keycap mounting boss will be transmitted to the keycap at the positioning member fastest and best, preventing the keycap from deforming due to uneven force, so that the four corners of the keycap can be separated from the four positioning members at the same time. Since the force on the keycap is more uniform, the keycap can move upward more stably and vertically to separate from the keycap mounting boss, preventing the situation that the keycap is tilted and scratched or strained on the side wall of the keycap mounting boss due to uneven force on the keycap, and ensuring the quality and qualification rate of the keycap.

[0029] See Figures 1 to 3 As shown, the positioning slot 2 includes two front-side positioning slots 5 and two rear-side positioning slots 6. The two front-side positioning slots 5 are respectively arranged on the left and right sides of the front end of the top surface of the keycap mounting boss 1;

[0030] The two rear-side positioning slots 6 are respectively arranged on the left and right sides of the rear end of the top surface of the keycap mounting boss 1.

[0031] The positioning member 3 in the rear-side positioning slot 6 is a cross bar 7. The cross bar 7 is arranged in the middle of the rear-side positioning slot 6, and both ends of the cross bar 7 are connected to the left inner wall and the rear inner wall of the rear-side positioning slot 6 respectively.

[0032] The positioning member 3 in the front-side positioning slot 5 is a protrusion 8. The protrusion 8 is installed on the inner wall of the inner end of the front-side positioning slot 5.

[0033] In this embodiment, the positioning clips on both sides of the rear end of the keycap are respectively inserted into the corresponding rear positioning grooves, and are clamped and limited with the corresponding cross bar to achieve the limitation of the rear side of the keycap, and the positioning clips on both sides of the front end of the keycap are respectively inserted into the corresponding front positioning grooves, and the protrusions are pressed against the side walls of the positioning clips to achieve the limitation of the front side of the keycap, and then the limitation of the four corners of the keycap is achieved, so that the keycap is firmly installed on the keycap mounting boss, and there will be no shaking or other problems during the painting process, thereby ensuring the stability and quality of the painting, and also ensuring that the thickness of the paint surface is uniform and qualified. When the keycap needs to be removed from the keycap mounting boss, the four top rods extend upward from the top hole at the same time and contact the inner wall of the keycap, pushing the keycap to move upward axially relative to the keycap mounting boss, so that the positioning clamps of the keycap are separated from the crossbar and the protrusion respectively, so that the keycap will not deform upward in the middle part and inward at the bottom of the outer edge due to force, and the side of the inner wall of the keycap and the side of the keycap mounting boss are prevented from scratching or pulling the keycap, thereby ensuring the quality and qualified rate of the keycap. Among them, the two top holes on the front side are set between the two front positioning grooves, and the two top holes on the rear side are set between the two rear positioning grooves.

[0034] Further, the outer end of the protrusion is an arc surface or a spherical surface. Preferably, the outer end surface of the protrusion is a spherical surface, the inner end of the protrusion is connected to the inner wall of one side of the front positioning groove, and there is a distance between the outer end and the inner wall of the other side of the front positioning groove, and the distance is used for the positioning clamp of the keycap to make way for the insertion, and at the same time, the inner end of the protrusion is against the side wall of the positioning clamp of the keycap to clamp and position it.

[0035] See also Figure 2 As shown, two longitudinal cavities 9 are provided on the bottom surface of the key cap mounting boss 1, the bottoms of the two left positioning grooves 2 are connected to the left longitudinal cavity 9, and the bottoms of the two right positioning grooves 2 are connected to the right longitudinal cavity 9.

[0036] By setting the longitudinal cavity, the material used for the keycap mounting boss can be reduced as much as possible, thereby reducing the cost. At the same time, the longitudinal groove is not set at the top hole, so that the inner wall of the top hole will be longer. In the process of the push rod moving in the top hole, the movement of the push rod can be limited and guided to prevent the push rod from self-deformation and bending due to its long length. In the process of the push rod extending to push the keycap off the keycap mounting boss, the push rod is in a state as vertical as possible to the keycap, thereby ensuring that the keycap and the keycap mounting boss will not be scratched or strained.

[0037] More preferably, a connecting cavity 10 is further provided in the middle of the bottom surface of the keycap mounting boss 1 to connect the two longitudinal cavities 9, and the top hole 4 is arranged beside the connecting cavity 10, two top holes are arranged on the front side of the connecting cavity, and the other two top holes are arranged on the rear side of the connecting cavity. The longitudinal cavity is arranged between the two front top holes and the two rear top holes to reduce the material as much as possible and reduce the cost. The connecting cavity and the longitudinal cavity form an "I"-shaped structure.

[0038] See also Figure 1 , 3 As shown, a concave groove 11 is provided at the center of the top surface of the key cap mounting boss 1 , and the four top holes 4 are respectively arranged on the sides of the groove 11 .

[0039] The setting of the groove plays a role of alignment. When a robot or other automated equipment installs the keycap on the corresponding keycap mounting boss, the groove can serve as a positioning reference for an industrial camera or other positioning mechanism, so that the keycap can be accurately installed on the keycap mounting boss. At the same time, it can also reduce the material used for the keycap mounting boss and reduce costs.

[0040] See also Figure 1 , 3 As shown, two of the top holes are arranged at a transverse interval on the front side of the groove, and another two of the top holes are arranged at a transverse interval on the rear side of the groove.

[0041] Taking the direction shown in the figure as an example, the keycap mounting boss is a left-right symmetrical structure, which is easy to process, has a relatively lower processing cost, and has better stability.

[0042] See also Figure 4 As shown, the utility model also provides a keycap painting carrier, including a carrier plate 21, and also includes the above-mentioned keycap painting carrier assembly, the keycap mounting boss 1 is installed on the top surface of the carrier plate 21, and the bottom surface of the carrier plate 21 is provided with a yield cavity connected to the corresponding top hole 4.

[0043] Among them, the carrier board can be directly installed on the base plate, and the keycap mounting boss is used for installing the keycaps. According to how many keycaps are required on the corresponding laptop computer, corresponding keycap mounting bosses are also provided on the carrier board.

[0044] Wherein, the key cap mounting boss and the carrier plate are an integral structure.

[0045] In this way, the keycap mounting boss and the carrier can be quickly manufactured. Preferably, the carrier plate and the keycap mounting boss are made of plastic, so that they can be quickly molded as a whole, with a fast processing speed and low cost.

[0046] Of course, other structural keycap painting carrier components will also be provided on the carrier board. Different structural keycap painting carrier components are set according to different keycaps to be applicable to different keycaps for painting support and positioning.
