Description

Technical Field

[0001] This utility model belongs to the field of scissor-foot production technology, specifically a scissor-foot production displacement device with automatic positioning function. Background Technology

[0002] Scissor-switch is a computer keyboard term, a commonly used modern term, widely applied in fields such as motors, sports, and medicine. Membrane keyboards, depending on the key structure, can be divided into three types: volcano structure, column structure, and scissor-switch structure. The scissor-switch structure consists of two parts: an upper support connected to the bottom of the keycap and a lower support connected to the keyboard base.

[0003] In the current production of keyboard scissor-switch feet, the upper and lower brackets need to be installed together. However, due to the small size of the upper and lower brackets, companies generally use manual labor to align and press them together during the process of positioning and contacting the upper and lower brackets and aligning the connecting parts of the upper and lower brackets. This results in high labor costs and low efficiency.

[0004] Therefore, this utility model provides a scissor-foot production displacement device with automatic positioning function. Utility Model Content

This step, by setting the first and second crossbeams to cooperate with the chassis to maintain the stability of the second and third threaded rods, avoids the second and third threaded rods from shifting during movement, improves the stability of the device, helps to extend the service life of the device, and reduces maintenance requirements.

[0010] Preferably, a limiting plate is provided on the top of the smooth block, and the limiting plate is set to the size of the lower bracket limiting groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown, an embodiment of the present invention provides a scissor-foot production displacement device with automatic positioning function, comprising a workbench 1, a first motor 11 fixedly connected to the side wall of the workbench 1, and a first threaded rod 16 fixedly connected to the output end of the first motor 11; a smooth block 12 threadedly connected to the side wall of the first threaded rod 16; a lower support limiting groove 13 opened on the top of the smooth block 12; a housing 15 fixedly connected to the side wall of the workbench 1; a second threaded rod 110 rotatably connected to the top of the housing 15, and the two second threaded rods 110 being arranged correspondingly; a first transmission wheel 18 fixedly connected to the bottom of the two second threaded rods 110, and a first transmission track arranged between the two first transmission wheels 18. 19; A second motor 17 is fixedly connected to the bottom of one of the first transmission wheels 18; a first lifting block 120 is threadedly connected to the side wall of the second threaded rod 110; an upper support limiting groove 14 is provided on the side wall of the first lifting block 120; a double cylinder 130 is fixedly connected inside the first lifting block 120, and a tray 140 is fixedly connected to the output end of the double cylinder 130; during operation, the operator can place the lower support and upper support of the scissor foot in the predetermined positions of the smooth block 12 and the upper support limiting groove 14, respectively. The lower support of the scissor foot can be placed in the lower support limiting groove 13 opened at the top of the smooth block 12, while the upper support of the scissor foot is placed in the upper support limiting groove 14. 4. During this process, the device will be supported by the tray 140 to prevent it from falling. After the worker completes the placement of the upper and lower supports, they can first drive the first motor 11. Through the threaded connection between the first threaded rod 16 and the smooth block 12, and the sliding connection between the smooth block 12 and the worktable 1, the smooth block 12 will move to the bottom of the upper support limiting groove 14. Subsequently, the worker can drive the second motor 17. Since the first lifting block 120 is threadedly connected to the two second threaded rods 110, and the bottom of the two second threaded rods 110 is correspondingly fixed with the first transmission wheel 18, and the two first transmission wheels 18 are provided with a first transmission track 19, which is fixed to the chassis 15. When the internal second motor 17 is driven, the height of the first lifting block 120 will decrease. Finally, the operator can drive the double cylinder 130 to retract the tray 140. The upper support located inside the upper support limiting groove 14 will fall to the corresponding position inside the lower support limiting groove 13 after losing its bottom support, thus completing the positioning contact of the upper and lower supports. This step uses the upper support limiting groove 14 and the lower support limiting groove 13 to place the upper and lower supports. The positioning contact of the upper and lower supports is completed by using the limiting of the lower support limiting groove 13 and the upper support limiting groove 14, as well as the controllable detachment of the upper support. This is conducive to realizing automated scissor-foot upper and lower support alignment, reducing labor costs and improving efficiency.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, a third threaded rod 21 is rotatably connected to the top of the chassis 15; two second transmission wheels 22 are fixedly connected to the bottom of the two third threaded rods 21, and a second transmission track 23 is provided between the two second transmission wheels 22; a third motor 2 is fixedly connected to the bottom of one of the second transmission wheels 22; a second lifting block 24 is threadedly connected to the side wall of the two third threaded rods 21; a pressure plate 25 is fixedly connected to the side wall of the second lifting block 24; a pressure block 26 is fixedly connected to the bottom of the pressure plate 25, and multiple pressure blocks 26 are set to correspond to the size of the upper bracket limiting groove 14; during operation, after the positioning contact of the upper and lower brackets of the scissor foot is completed, the operator can drive the first motor 11 to make the smooth block 12 return to the bottom of the pressure plate 25, and then drive the third motor 2 to make the multiple pressure blocks 26 pass through the upper bracket limiting groove 14. The upper and lower supports are pressed against the top, thus completing the installation of the upper and lower supports. During the process, whenever the third motor 2 is driven, the power of the third motor 2 can be directly transmitted to the third threaded rod 21 fixed to its own output end. At the same time, it can be transmitted to another third threaded rod 21 through the second transmission wheel 22 and the second transmission track 23. After the two third threaded rods 21 rotate synchronously, the second lifting block 24 will move in the vertical direction. The pressure plate 25 plays the role of fixing the pressure block 26. This step controls the height of the pressure plate 25 and multiple pressure blocks 26 by setting the third motor 2, so that multiple pressure blocks 26 are pressed against the top of the upper and lower supports, and finally complete the installation of the upper and lower supports. This is conducive to realizing the automated installation of scissor-leg upper and lower supports, improving work efficiency and reducing labor costs.

[0027] like Figure 2 and Figure 5 As shown, a fixing protrusion 3 is fixedly connected to the side wall of the first lifting block 120, and multiple fixing protrusions 3 are arranged correspondingly; an extension block 32 is provided on the side wall of the upper bracket limiting groove 14, and multiple extension blocks 32 are arranged correspondingly; a reinforcing block 31 is fixedly connected between the second transmission track 23 and the fixing protrusion 3, and multiple reinforcing blocks 31 are arranged correspondingly; during operation, the multiple reinforcing blocks 31 fixed between the fixing protrusion 3 and the extension block 32 increase the fixed area between the two, thereby enhancing the fixed strength between the fixing protrusion 3 and the extension block 32. The extension block 32 is set on the side wall of the upper bracket limiting groove 14, and the extension block 32 is fixedly connected to the fixed protrusion 3 and the reinforcing block 31. The force-bearing distance of the upper bracket limiting groove 14 is increased, and the upper bracket limiting groove 14 will not easily deflect when subjected to force. This step strengthens the connection strength between the upper bracket limiting groove 14 and the adjacent components by setting the reinforcing block 31, thereby preventing the upper bracket limiting groove 14 from loosening or falling off during operation. The extension block 32 increases the force-bearing distance of the upper bracket limiting groove 14, thereby improving the stability of the upper bracket limiting groove 14.

[0028] like Figure 1 and Figure 3As shown, a first fixing block 4 and a second fixing block 41 are fixedly connected to the top of the chassis 15; a first crossbeam 42 is fixedly connected to the side wall of the first fixing block 4, and the first crossbeam 42 is rotatably connected to the second threaded rod 110; a second crossbeam 43 is fixedly connected to the side wall of the second fixing block 41, and the second crossbeam 43 is rotatably connected to the third threaded rod 21; during operation, the first crossbeam 42 and the second crossbeam 43, which are rotatably connected to the top of the second threaded rod 110 and the third threaded rod 21, can cooperate with the chassis 15 to maintain the stability of the second threaded rod 110 and the third threaded rod 21, and prevent them from malfunctioning during operation. During the process, tilting occurs. The first fixing block 4, which is fixed between the first crossbeam 42 and the chassis 15, serves to fix the first crossbeam 42, while the second fixing block 41, which is fixed between the second crossbeam 43 and the chassis 15, serves to fix the second crossbeam 43. This step, by setting the first crossbeam 42 and the second crossbeam 43 in conjunction with the chassis 15, maintains the stability of the second threaded rod 110 and the third threaded rod 21, preventing the second threaded rod 110 and the third threaded rod 21 from shifting during movement. This improves the stability of the device, helps extend its service life, and reduces maintenance requirements.

[0029] like Figure 2 As shown, a limiting plate 5 is provided on the top of the smooth block 12, and the limiting plate 5 is set to the size of the lower support limiting groove 13. During operation, the limiting plate 5 is set to the size of the lower support limiting groove 13. After the lower support is placed inside the lower support limiting groove 13, the operator can simultaneously place the limiting plate 5 inside the lower support limiting groove 13. The size of the surface groove of the limiting plate 5 is smaller than the internal groove of the lower support limiting groove 13, and the size of the surface groove of the limiting plate 5 is equal to the surface groove of the upper support limiting groove 14. The limiting plate 5 can restrict the falling process of the upper support. This step, by setting the limiting plate 5 between the lower support limiting groove 13 and the upper support limiting groove 14, prevents the upper support from shifting during the process of falling from the small groove of the upper support limiting groove 14 to the large groove of the upper support limiting groove 14, which helps to improve the installation accuracy of the scissor foot of the device.

[0030] like Figure 1 As shown, the top of the workbench 1 is fixedly connected to a limiting rod 6, and multiple limiting rods 6 are set at positions corresponding to the fixed protrusions 3. During operation, multiple limiting rods 6 are slidably connected to the fixed protrusions 3, and multiple limiting rods 6 can restrict the movement posture of the first lifting block 120 by means of this relationship. This step restricts the movement posture of the first lifting block 120 by setting the limiting rods 6, preventing it from tilting during movement, and improving the stability and durability of the device.

[0031] like Figure 3As shown, a dust removal groove 7 is provided on the side wall of the workbench 1, and the two dust removal grooves 7 are set corresponding to the positions of the smooth block 12. During operation, whenever the smooth block 12 moves to one end of the workbench 1, the dust and debris present on the side wall of the smooth block 12 can be discharged from the dust removal groove 7. This step, by opening dust removal grooves 7 on both sides of the workbench 1, avoids the accumulation of dust and debris inside the workbench 1, which helps to reduce the cleaning difficulty of the device and maintain the smooth operation of the components.

[0032] During operation, the operator can place the lower and upper supports of the scissor-foot mechanism into predetermined positions on the smoothing block 12 and the upper support limiting groove 14, respectively. The lower support of the scissor-foot mechanism can be placed in the lower support limiting groove 13 at the top of the smoothing block 12, while the upper support, when placed in the upper support limiting groove 14, will be supported by the tray 140 to prevent it from falling. After placing the upper and lower supports, the operator can first drive the first motor 11. Through the threaded connection between the first threaded rod 16 and the smoothing block 12, and the sliding connection between the smoothing block 12 and the worktable 1, the smoothing block 12 moves to the bottom of the upper support limiting groove 14. Subsequently, the operator can drive the second motor 17. Due to the connection between the first lifting block 120 and the two... The two second threaded rods 110 are threadedly connected, and the bottoms of the two second threaded rods 110 are respectively fixedly connected to the first transmission wheel 18. A first transmission track 19 is provided between the two first transmission wheels 18. After the second motor 17 fixed inside the housing 15 is driven, the height of the first lifting block 120 will decrease. Finally, the operator can drive the double cylinder 130 to retract the pallet 140. The upper support located inside the upper support limiting groove 14 will fall to the corresponding position inside the lower support limiting groove 13 after losing its bottom support, completing the positioning contact of the upper and lower supports. After the positioning contact of the upper and lower supports of the scissor foot is completed, the operator can drive the first motor 11 to make the smooth block 12 return to the bottom of the pressure plate 25, and then drive the third motor 2. This method allows multiple pressure blocks 26 to pass through the upper bracket limiting groove 14 and press against the top of the upper and lower brackets, thus completing the installation of the upper and lower brackets. During the process, whenever the third motor 2 is driven, the power of the third motor 2 can be directly transmitted to the third threaded rod 21 fixed to its own output end, and simultaneously transmitted to another third threaded rod 21 through the second transmission wheel 22 and the second transmission track 23. After the two third threaded rods 21 rotate synchronously, the second lifting block 24 will move in the vertical direction. The pressure plate 25 serves to fix the pressure blocks 26. Multiple reinforcing blocks 31 fixed between the fixed protrusion 3 and the extension block 32 increase the fixed area between the two, thereby enhancing the fixed strength between the fixed protrusion 3 and the extension block 32. The extension block 32 is mounted on the side wall of the upper bracket limiting groove 14, and is fixedly connected to the fixing protrusion 3 and the reinforcing block 31. The force-bearing distance of the upper bracket limiting groove 14 is increased, and the upper bracket limiting groove 14 will not easily deflect under force. The first crossbeam 42 and the second crossbeam 43, which are rotatably connected to the top of the second threaded rod 110 and the third threaded rod 21, can cooperate with the chassis 15 to maintain the stability of the second threaded rod 110 and the third threaded rod 21 and prevent them from tilting during operation. The first fixing block 4, which is fixed between the first crossbeam 42 and the chassis 15, serves to fix the first crossbeam 42, while the second fixing block 41, which is fixed between the second crossbeam 43 and the chassis 15, serves to fix the second crossbeam 43.The limiting plate 5 is sized to correspond to the limiting groove 13 of the lower support. After the lower support is placed inside the limiting groove 13, the operator can simultaneously place the limiting plate 5 inside the limiting groove 13. The surface groove of the limiting plate 5 is smaller than the internal groove of the lower support limiting groove 13, and the surface groove of the limiting plate 5 is equal to the surface groove of the upper support limiting groove 14. The limiting plate 5 can restrict the descent of the upper support. Multiple limiting rods 6 are slidably connected to the fixed protrusion 3. These limiting rods 6 can restrict the movement of the first lifting block 120 using this connection. Whenever the smooth block 12 moves to one end of the worktable 1, dust and debris on the sidewall of the smooth block 12 can be discharged from the cleaning trough 7.
