[0031] The automatic oiling device for keyboard switch covers of the present invention includes a frame 1, a guide rail 2, a pressure plate 3, an oiling block 4, an oil box 5, a drive mechanism 6, and an oiling reversing mechanism 7. The guide rail 2, the oil box 5, and the drive mechanism 6 are all mounted on the frame 1. The oiling block 4 is connected to the drive mechanism 6. The pressure plate 3 has a recessed model that matches the keyboard switch cover.

[0032] For details, please refer to Figures 1 to 3 As shown, the guide rail 2 has a slot 21 and a through hole. The slot 21 is used to place the keyboard switch cover. The oiling block 4 is located below the guide rail 2 at the position corresponding to the through hole. The pressure plate 3 is located above the through hole at the position corresponding to the oiling block 4. When the drive mechanism 6 is working, it drives the oiling block 4 to extend out of the through hole. Here, the drive mechanism 6 can be selected as a cylinder to facilitate the extension and reset of the oiling block 4.

[0033] In a preferred embodiment, the oil box 5 is located above the drive mechanism 6. The oiling block 4 passes through the bottom of the oil box 5 and is placed inside the oil box. Before oiling, the upper part of the oiling block 4 is immersed in oil. To ensure the amount of oil in the oil box 5 during operation, the oil box 5 is provided with an oil filling hole 51, through which oil can be injected into the oil box 5 at regular intervals and in a measured amount. To prevent the oil box 5 from overflowing due to overfilling, the oil box 5 is provided with an oil drain hole 52, through which oil can be drained at regular intervals and in a measured amount.

[0034] In a preferred embodiment, the oiling reversing mechanism 7 is located on one side of the frame 1. The oiling reversing mechanism includes a frame 2 71, a reversing link 72, a transmission block 73, and a drive mechanism 2 74. One end of the reversing link 72 is connected to the pressure cover plate 3, and the other end of the reversing link 72 is connected to the transmission block 73 through a slide rail 75. The drive mechanism 2 74 includes a stepper motor 741, a transmission spindle 742, and a cam 743. The stepper motor 741 is mounted on the frame 2 71, and the transmission spindle 742 is connected to the stepper motor 741. The transmission spindle 742 is also connected to the cam 743, and the cam 743 is movably fitted in the transmission block 73.

[0035] When the oiling reversing mechanism 7 is working, the drive mechanism 2 74 is working, that is, the stepper motor 741 drives the transmission main shaft 742 to rotate, the transmission main shaft 742 drives the cam 743 to rotate, the cam 743 drives the transmission block 73 to move in the circumferential direction in the transmission block 73, and then drives the reversing linkage 72 to move in the circumferential direction through the slide rail 75, and the reversing linkage 72 then drives the pressure cover plate 3 to move in the circumferential direction.

[0036] When the keyboard switch cover to be oiled is placed in the slot 21 at the through hole on the guide rail 2, that is, when the keyboard switch cover is in the oiling station, the drive mechanism 6 drives the oiling block 4 to extend out of the oil box 5, and the oiled block 4 extends out of the through hole. At the same time, the stepper motor 741 of the drive mechanism 74 works, the stepper motor 741 drives the transmission spindle 742 to rotate, the transmission spindle 742 drives the cam 743 to rotate, the cam 743 drives the transmission block 73 to move horizontally in the circumferential direction in the transmission block 73, the transmission block 73 drives the reversing linkage 72 to move horizontally in the circumferential direction, and the reversing linkage 72 drives the pressure cover plate 3 to move horizontally in the circumferential direction. When the pressure cover plate 3 drives the keyboard switch cover to move horizontally in the circumferential direction, the position of the keyboard switch cover to be oiled touches the oiling block 4, thereby realizing oiling at different positions in the horizontal circumferential direction of the keyboard switch cover, thus reducing labor intensity, increasing production efficiency, ensuring uniform oiling quality, and improving product quality.

[0037] Example 2

[0038] The automatic oiling device for the keyboard switch cover in this embodiment is similar to that in Embodiment 1. Furthermore, in this embodiment, a pressure cylinder 76 is also installed on the frame 71, and one side of the reversing connecting rod 72 is engaged with the pressure cylinder.

[0039] Specifically, when the pressing cylinder 76 is working, it drives the reversing linkage 72 to move up and down along the slide rail 75, and the reversing linkage 72 then drives the pressing cover plate 3 to move up and down.

[0040] When the keyboard switch cover to be oiled is placed in the slot 21 at the through hole on the guide rail 2, that is, when the keyboard switch cover is in the oiling station, the drive mechanism 6 drives the oiling block 4 to extend out of the oil box 5, and the oiled block 4 extends out of the through hole. At the same time, the stepper motor 741 of the pressing cylinder 76 and the drive mechanism 74 works. The pressing cylinder 76 drives the reversing linkage 72 to move the pressing cover 3 downward, so that the keyboard switch cover is placed in the pressing cover 3. Thus, the pressing cylinder 76 can drive the keyboard switch cover to move up and down through the reversing linkage 72 and the pressing cover 3. The stepper motor 741 drives the transmission spindle 742 to rotate. The transmission spindle 742 drives the cam 743 to rotate. The cam 743 drives the transmission block 73 to move in the circumferential direction in the transmission block 73. The transmission block 73 drives the reversing linkage 72 to move in the circumferential direction. The reversing linkage 72 then drives the pressing cover 3 to move in the circumferential direction. When the pressure plate 3 drives the keyboard switch cover to move up and down and in a circular direction, the area of ​​the keyboard switch cover that needs to be oiled will touch the oiling block 4, thereby achieving oiling of different positions of the keyboard switch cover, resulting in low labor intensity, high production efficiency, uniform oiling quality, and high product quality.

[0041] Example 3

[0042] The automatic oiling device for the keyboard switch cover in this embodiment is similar to that in Embodiment 1. Furthermore, this embodiment also includes an oil scraping mechanism 8, which comprises an oil scraping cylinder 81 and an oil scraping plate 82. Please refer to [further details omitted]. Figure 2 As shown.

[0043] Specifically, the oil scraping cylinder 81 is horizontally mounted on the frame 1, and the oil scraping plate 82 is connected to the oil scraping cylinder 81. When the amount of oil required for the keyboard switch cover is small, the oil scraping cylinder 81 drives the oil scraping plate 82 to retract inward toward the oiling block 4. When it moves to a set distance, the drive mechanism 6 drives the oiling block 4 to rise, so that the oil scraping plate 82 can partially scrape off the oil around the oiling block 4, leaving the required thin oil film layer to apply oil to the keyboard switch cover, thereby achieving precision oiling.

[0044] Example 4

[0045] The automatic oiling equipment for the keyboard switch cover in this embodiment is similar to that in Embodiment 1. Furthermore, this embodiment also includes a feeding mechanism 9, which includes a frame 91, a vibratory feeder, a linear feeder 92, an X-axis feeding cylinder 93, a Y-axis feeding cylinder 94, and a clamping block 95.

[0046] Specifically, the linear feeder 92 and the X-axis feeding cylinder 93 are respectively installed on the frame 3 91, the Y-axis feeding cylinder 94 is connected to the X-axis feeding cylinder 93, the clamping block 95 is connected to the Y-axis feeding cylinder 94, and the end of the linear feeder 92 is connected to the starting end of the guide rail 2.

[0047] When the feeding mechanism 9 is working, the keyboard switch cover enters the linear feeder 92 from the vibratory feeder. After being conveyed forward to the end in the linear feeder 92, the keyboard switch cover enters the starting end of the guide rail 2. Then, the X-axis feeding cylinder 93 drives the clamping block 95 to move and clamp the keyboard switch cover. Then, the Y-axis feeding cylinder 94 works to move the keyboard switch cover on the clamping block 95 to the oiling station, that is, the slot 21 at the through hole of the guide rail 2. This greatly improves the feeding efficiency of the keyboard switch cover, facilitates the oiling of the keyboard switch cover, and greatly improves the degree of automation.

[0049] The automatic oiling device for the keyboard switch cover in this embodiment is similar to that in embodiment four. Furthermore, in this embodiment, the clamping blocks 95 are set in two groups. The position of the first group of clamping blocks corresponds to the linear feeder 92, and the position of the second group of clamping blocks corresponds to the slot 21 at the through hole of the guide rail 2.

[0050] Specifically, when the feeding mechanism 9 is working, the keyboard switch cover enters the linear feeder 92 from the vibratory feeder. After being conveyed forward to the end in the linear feeder 92, the keyboard switch cover enters the starting end of the guide rail 2. Then, the X-axis feeding cylinder 93 drives the first set of clamping blocks to move and clamp the keyboard switch cover. At the same time, the second set of clamping blocks clamps the keyboard switch cover that has been coated with oil at the oiling station. Then, the Y-axis feeding cylinder 94 works to move the keyboard switch cover on the first set of clamping blocks to the oiling station, that is, to the slot 21 at the through hole of the guide rail 2. At the same time, the keyboard switch cover that has been coated with oil on the second set of clamping blocks is placed on the guide rail 2 for discharge, thereby greatly improving the feeding efficiency and discharge efficiency of the keyboard switch cover products.

[0051] Example 6

[0052] The automatic oiling device for the keyboard switch cover in this embodiment is similar to that in embodiment five. Furthermore, in this embodiment, a through-beam optical fiber 96 is installed on the linear feeder 92 to detect whether the keyboard switch cover is being conveyed to the correct position. The through-beam optical fiber 96 provides a command signal to the X-direction feeding cylinder 93.

[0053] Specifically, when the feeding mechanism 9 is working, the keyboard switch cover enters the linear feeder 92 from the vibratory feeder. After being conveyed forward to the end in the linear feeder 92, the keyboard switch cover enters the starting end of the guide rail 2. The through-beam fiber optic 96 senses that the keyboard switch cover has been conveyed to the correct position. After receiving the command signal, the X-axis feeding cylinder 93 starts working.
