DETAILED DESCRIPTION

[0030] In order to make the person skilled in the art better understand the technical scheme in the utility model, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0031] The keycap 50 described below can be the keycap of space bar or other keycaps needing balance bar support.

[0032] As Figures 1-8 shown, the keycap balance bar assembly device 100 (hereinafter referred to as assembly device 100) in an embodiment of the utility model includes a rack and an assembly mechanism. The rack is used to provide installation space, including an assembly table 14, as Figure 4 shown, the assembly table 14 is provided with a groove for placing the keycap 50, the bottom edge of the groove is provided with a support surface 141, and a channel 142 for the balance bar to pass through. Referring to Figures 5 to 7 , the assembly mechanism is fixed on the rack, including a first pressing assembly 21 and a second pressing assembly 22, the first pressing assembly 21 includes a pressing block 211 arranged above the assembly table 14, and a first power source 212 connected and driving the pressing block 211 to move up and down. The second pressing assembly 22 includes a plurality of ejector rods 221 arranged below the assembly table 14, and a second power source 222 connected and driving the ejector rods 221 to move up and down.

[0033] In the working process, referring to Figure 8 and Figure 9As shown, the keycap 50 is placed on the support surface 141, while the stabilizer bar 60 is supported on the top rod 221. Then, the first power source 212 drives the pressure block 211 downwards to press against the keycap 50, and the second power source 222 drives the top rod 221 upwards, pushing the stabilizer bar and securing it into the clip 51 on the keycap 50, thus completing the assembly. This assembly equipment 100 has a simple structure, can accurately fasten the stabilizer bar into the clip 51 on the keycap 50, requires little time, and has high assembly efficiency.

[0034] Preferably, the second pressing assembly 22 includes a first top plate 223, on which a first positioning groove 2231 for placing the balance bar 60 is provided, and a through groove 2232 communicating with the first positioning groove 2231. The balance bar is placed in the first positioning groove 2231, and the push rod 221 pushes the balance bar upward through the through groove 2232. The first positioning groove 2231 is used to ensure the position of the balance bar and prevent displacement during assembly, which could lead to assembly failure. For example, in Figure 8 In this embodiment, one U-shaped and one first positioning groove 2231 with bends at both ends are respectively opened on the first top plate 223, thus accommodating one U-shaped and one balance bar 60 with bends at both ends. Of course, the specific number of balance bars 60 can be determined according to specific circumstances, and this embodiment is not limited.

[0035] It is conceivable that the top of the push rod 221 can adopt an arc-shaped design, that is, a concave arc-shaped surface is formed at the top, in order to ensure the position of the buckle 51 when pushing the balance bar upward and assembling it onto the keycap 50, so as to avoid displacement during the assembly process and cause assembly failure.

[0036] like Figure 7 As shown, the second pressing assembly 22 also includes a second top plate 224 for fixing the top rod 221, which is disposed below the first top plate 223 and is driven to move up and down by the second power source 222.

[0037] Multiple clips 51 for fixing the balance bar are provided on the keycap 50. To improve the success rate of assembly and avoid the situation where the clips are not engaged with the balance bar, a large number of push rods 221 are fixed on the second top plate 224. The push rods 221 are distributed on the entire balance bar to increase the number of force points on the balance bar when it is engaged, especially at the corners, so as to ensure that all clips are engaged with the balance bar.

[0038] Further, a third top plate 228 is arranged between the first top plate 223 and the second top plate 224, and a plurality of limiting rod sets corresponding to the number of the top rods 221 are fixed on the third top plate 228. Each limiting rod set is composed of two parallel limiting rods 229. The top rod 221 passes through the third top plate 228, and each top rod 221 is arranged between the corresponding limiting rod set and can move up and down in the respective limiting rod set (i.e. moves up and down between the two limiting rods 229). The through slot 2232 can simultaneously accommodate the top rod 221 and the limiting rod 229 to pass through. The third top plate 228 is supported on the second top plate 224 by a retractable reset member (such as a spring, not shown in the figure).

[0039] As shown in Figure 9 , in the normal state, the top of the limiting rod 229 is higher than the top of the top rod 221, and the balance bar 60 is placed between the limiting rod 229 and the top rod 221. During assembly, the second power source 222 drives the second top plate 224 and the third top plate 228 to move upwards, thereby driving the limiting rod 229 and the top rod 221 to move upwards. The limiting rod 229 first contacts the keycap 50 (as shown in Figure 10 ), and stops moving upwards under the blockage of the pressing block 211. At this time, the top rod 221 continues to drive the balance bar 60 to move upwards under the action of the second power source 222, and finally clamps the balance bar 60 to the buckle 51 of the keycap 50 (as shown in Figure 11 ). Then the second power source 222 drives the second top plate 224 and the third top plate 228 to move downwards, and the second top plate 224 and the third top plate 228 move away from each other under the action of the reset member, and the top rod 221 moves to the lower side of the limiting rod 229. This arrangement further ensures that the balance bar can be correctly moved to the position of the buckle, thereby ensuring the success rate of assembly.

[0040] In an embodiment, the assembly device 100 further comprises a rack 30 fixed on the rack, which is an upper feeding mechanism for storing balance bars, and is arranged on one side of the assembly table 14 and above the first top plate 223. The second pressing assembly 22 further comprises a third power source 225 fixed on the rack, which is connected to and drives the first top plate 223 to move between the assembly table 14 and the rack 30. When the third power source 225 drives the first top plate 223 to move below the rack 30, the rack 30 releases a group of balance bars into the first positioning slot 2231; then the third power source 225 is reversed to drive the first top plate 223 to move below the assembly table 14, and then the second power source 222 drives the balance bar to move upwards and completes the assembly.

[0041] Specifically, the second pressing assembly 22 comprises a first mounting frame 226, and the first top plate 223 and the second power source 222 are fixed on the first mounting frame 226. The third power source 225 is connected to and drives the first mounting frame 226 to move between the assembly table 14 and the rack 30.

[0042] In an embodiment, the rack 30 is an automatic feeding mechanism, and the balance bars are arranged on the rack 30 from top to bottom and fall into the first positioning groove 2231 by their own gravity. Therefore, the top surface of the first mounting frame 226 is a flat surface flush with the top surface of the first top plate 223, and there is a gap between the bottom of the rack 30 and the top surface of the first mounting frame 226, which is smaller than the thickness of the balance bar, so that the balance bar is always clamped on the rack 30 during the movement of the first mounting frame 226 driven by the third power source 225. Only when the first positioning groove 2231 moves to the position directly below the rack 30 and aligns with the balance bar, the balance bar falls into the first positioning groove 2231, without the need for manual intervention, as long as there are enough balance bars stored on the rack 30.

[0043] In order to improve the stability of the movement of the first mounting frame 226, the second pressing assembly 22 further comprises a guide rail 2271 fixed on the rack and a sliding block 2272 supported on the guide rail 2271, and the first mounting frame 226 is fixed on the sliding block 2272, so that the weight is borne by the guide rail 2271 and the sliding block 2272, and the third power source 225 is only used to drive the first mounting frame 226 to move without bearing the weight, thereby reducing the load and ensuring stable operation for a long time.

[0044] As shown in Figure 3 , the rack comprises a base plate 11 and a second mounting frame 12 fixed on the base plate 11, and the second pressing assembly 22 and the assembly table 14 are fixed on the base plate 11, while the first pressing assembly 21 and the rack 30 are fixed on the second mounting frame 12. A transverse sliding groove 121 is formed on the second mounting frame 12, and a fixing block 13 is arranged in the sliding groove 121, and the rack 30 is fixed on the fixing block 13. This is intended to fine-tune the position of the rack 30, i.e. the falling position of the balance bar, so as to better adapt to the assembly of space bars of different lengths.

[0045] In an embodiment, the support surface 141 is recessed on the surface of the assembly table 14, and its shape and size are the same as those of the keycap. After the keycap is embedded on the support surface 141, it can be prevented from shifting during assembly. The pressing block 211 has the same shape and size as the keycap, so it can completely fit the keycap to prevent the keycap from bending during assembly due to lack of support.

[0046] As shown in Figure 4 , the channel 142 is a rectangular opening formed on the assembly table 14, which has the same shape as the space bar but is slightly smaller in size, and the support surface 141 is formed around the channel 142. An inclined surface 143 extending towards the channel 142 and the support surface 141 is further provided on the surface of the assembly table 14 to facilitate the movement of the keycap onto the support surface 141, further reducing the assembly time and improving the production efficiency.

[0047] A control cabinet 40 is also fixed on the frame, which displays the operation parameters of the first and second pressing assemblies 21 and 22, and provides functions such as main switch, emergency stop, etc.

[0048] In an embodiment, cylinders are used as the first, second and third power sources 212, 222 and 225. Of course, in other embodiments, other devices can be used as the power sources, and the present embodiment is not limited thereto.

[0049] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to embrace all changes falling within the meaning and range of equivalents of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
