Description

[Technical field]

[0001] The present invention belongs to the technical field of linear drive modules, and in particular relates to a space-saving two-dimensional transfer drive module and a key cap detection mechanism. [Background technology]

[0002] The keyboard is generally assembled from an aluminum substrate, a circuit board, a scissor support frame, and keycaps. If the elasticity or pull-out force of the keyboard keycaps is poor, it will seriously affect the service life and mechanical feel of the keyboard after it is made into a finished product. Therefore, after the keycaps are installed on the keyboard, in order to ensure the reliability of subsequent use, it is necessary to test the pull-out force of the keyboard keycaps after assembly.

[0003] There are a lot of automatic detection devices for keycap pull-out force in the prior art. Generally, in order to improve the detection efficiency, multiple pull-out detection heads are set to simultaneously detect multiple keycaps of a keyboard. For example, patent CN113970474A discloses a keycap detection mechanism and detection method that can effectively avoid the pull block hook from being broken. However, the setting of multiple detection pull-out heads generally requires the configuration of multiple independent drive modules. Each drive module needs to be able to drive a detection pull-out head to achieve horizontal axial and Z-axis transfer. The horizontal axial transfer drive is used to move between different rows of the keyboard, and the Z-axis transfer drive is used to drive the detection pull-out head to frequently pull the keycap upward. The setting of multiple drive modules will undoubtedly cause the driving part of the detection mechanism to have a cumbersome and complex structure and occupy a large space. The setting of multiple motors also causes the overall weight to be heavy and the space to be occupied, which is not conducive to the high-speed operation of the keycap pull-out test.

[0004] Therefore, it is necessary to provide a new space-saving two-dimensional transfer drive module and keycap detection mechanism to solve the above technical problems. [Summary of the invention]

[0037] Embodiment 1:

[0038] Please refer to Figure 1-Figure 10 The present embodiment is a keycap detection mechanism 100 , which includes a two-dimensional transfer driving module 1 and a keycap detection module 2 arranged at a movable end of the two-dimensional transfer driving module 1 .

[0039] The two-dimensional transfer drive module 1 includes a first mounting seat 11, an X-axis drive module 12 arranged on the first mounting seat 11, a first movable frame 13 arranged at the movable end of the X-axis drive module 12, a second mounting seat 14 fixed below the first movable frame 13, a Z-axis drive module 15 arranged on the second mounting seat 14, and a second movable frame 16 arranged at the movable end of the Z-axis drive module 15.

[0040] The X-axis driving module 12 includes a first rectangular coil 121 fixed on the first movable frame 13, a first magnetic block assembly 122 and a second magnetic block assembly 123 arranged on the first mounting seat 11 and extending along the X-axis; the first magnetic block assembly 122 and the second magnetic block assembly 123 both include a first magnetic block strip 1221 and a second magnetic block strip 1222 arranged in parallel and spaced apart, and a first magnetic channel 1223 is formed between the first magnetic block strip 1221 and the second magnetic block strip 1222; in the first magnetic block assembly 122 and the second magnetic block assembly 123, the magnetic field directions in the first magnetic channel 1223 are opposite and perpendicular to the straight side of the first rectangular coil 121; a pair of opposite side sides of the first rectangular coil 121 pass through the first magnetic channel 1223 in the first magnetic block assembly 122 and the second magnetic block assembly 123 respectively. Current flows inside the first rectangular coil 121.

[0041] The direction of the magnetic field in the first magnetic channel 1223 is set parallel to the Z axis or parallel to the Y axis.

[0042] The first rectangular coil 121 is a three-dimensional rectangular structure as a whole, and its horizontal length extends along the Y-axis direction, and has a certain material width in the X-axis direction. By increasing the material width of the first rectangular coil 121, its area in the first magnetic channel 1223 can be increased, thereby increasing the driving force. The first rectangular coil 121 includes an upper straight line segment 1211, a right straight line segment 1212, a lower straight line segment 1213, and a left straight line segment 1214.

[0043] In this embodiment, the first magnetic block assembly 122 and the second magnetic block assembly 123 are arranged on the first mounting seat 11 in an upper and lower distribution. The first rectangular coil 121 embraces the first mounting seat 11, and the upper straight line segment 1211 passes through the first magnetic channel 1223 of the first magnetic block assembly 122 in the Y direction, and the lower straight line segment 1213 passes through the first magnetic channel 1223 of the second magnetic block assembly 123 in the Y direction. Since the current flows in the upper straight line segment 1211 and the lower straight line segment 1213 in the first rectangular coil 121 in opposite directions, and the magnetic field directions in the first magnetic channel 1223 of the first magnetic block assembly 122 and the second magnetic block assembly 123 are also opposite, therefore, according to the left-hand rule, the Ampere force directions generated by the first magnetic block assembly 122 and the second magnetic block assembly 123 on the first rectangular coil 121 are in the same direction, so that the first rectangular coil 121 can be driven to move in the X direction, and by changing the current direction in the first rectangular coil 121, the first rectangular coil 121 can be moved in the positive direction and the reverse direction along the X direction.

[0044] In other embodiments, the first magnetic block assembly 122 and the second magnetic block assembly 123 are arranged on the first mounting base 11 in a left-right distribution, the first rectangular coil 121 is encircled on the first mounting base 11 and the left straight line segment 1214 passes through the first magnetic channel 1223 of the first magnetic block assembly 122 in the Z direction, and the right straight line segment 1212 passes through the first magnetic channel 1223 of the second magnetic block assembly 123 in the Z direction.

[0045] In this embodiment, the first mounting seat 11 includes an intermediate mounting plate 111, an upper mounting plate 112 fixed above the intermediate mounting plate 111, and a lower mounting plate 113 fixed below the intermediate mounting plate 111. A first mounting cavity (not marked in the figure) for mounting the first magnetic block assembly 122 is formed between the upper and lower opposite surfaces of the intermediate mounting plate 111 and the upper mounting plate 112; a second mounting cavity (not marked in the figure) for mounting the second magnetic block assembly 123 is formed between the lower mounting plate 113 and the upper and lower opposite surfaces of the intermediate mounting plate 111. The first magnetic block strip 1221 in the first magnetic block assembly 122 is fixedly mounted on the top of the inner wall of the first mounting cavity, and the second magnetic block strip 1222 is fixedly mounted on the bottom of the inner wall of the first mounting cavity; the first magnetic block strip 1221 in the second magnetic block assembly 123 is fixedly mounted on the bottom of the inner wall of the second mounting cavity, and the second magnetic block strip 1222 is fixedly mounted on the top of the inner wall of the second mounting cavity.

[0046] In another embodiment, the first mounting seat 11 may also include an intermediate mounting plate 111, a left mounting plate (not marked in the figure) fixed to the left side of the intermediate mounting plate 111, and a right mounting plate (not marked in the figure) fixed to the right side of the intermediate mounting plate 111. A third mounting cavity (not marked in the figure) for mounting the first magnetic block assembly 122 is formed between the intermediate mounting plate 111 and the two side surfaces opposite to each other on the left and right sides of the left mounting plate; a fourth mounting cavity (not marked in the figure) for mounting the second magnetic block assembly 123 is formed between the two side surfaces opposite to each other on the left and right sides of the right mounting plate and the intermediate mounting plate 111. The first magnetic block strip 1221 in the first magnetic block assembly 122 is fixedly mounted on the left inner wall of the second mounting cavity, and the second magnetic block strip 1222 is fixedly mounted on the right inner wall of the first mounting cavity; the first magnetic block strip 1221 in the second magnetic block assembly 123 is fixedly mounted on the right inner wall of the second mounting cavity, and the second magnetic block strip 1222 is fixedly mounted on the left inner wall of the second mounting cavity.

[0047] In order to ensure the stability of the first movable frame 13 moving along the X direction, the first movable frame 13 in this embodiment is a vertically distributed rectangular frame structure as a whole, and forms a surrounding notch 131. The top and bottom of the inner wall of the surrounding notch 131 are both provided with a first slider 132, and the left and right sides of the inner wall are both provided with a second slider 133. The first mounting seat 11 is provided with a first slide rail 114 that cooperates with the first slider 132 and a second slide rail 115 that cooperates with the second slider 133. The first movable frame 13 is guided for transfer in the X direction from multiple side surfaces, which ensures the stability of its transfer in the X direction on the one hand, and ensures the smoothness of the first rectangular coil 121 and the first magnetic block assembly 122 and the second magnetic block assembly 123 on the other hand, effectively preventing the first rectangular coil 121 from being stuck in the first magnetic channel 1223.

[0048] The first rectangular coil 121 is fixedly disposed in the surrounding slot 131. Specifically, the left and right sides of the first rectangular coil 121 are respectively fixedly connected to the left and right inner walls of the surrounding slot 131, or the upper and lower sides of the first rectangular coil 121 are respectively fixedly connected to the upper and lower inner walls of the surrounding slot 131. When one pair of two opposite sides of the first rectangular coil 121 is used to be fixedly connected to the surrounding slot 131, the other pair of two opposite sides is used to pass through the first magnetic channel 1223 for power transmission.

[0049] The Z-axis driving module 15 includes a second rectangular coil 151 fixed on the second movable frame 16, a third magnetic block assembly 152 and a fourth magnetic block assembly 153 arranged on the second mounting seat 14 and extending along the Z-axis; the third magnetic block assembly 152 and the fourth magnetic block assembly 153 both include a pair of third magnetic block strips 1521 and fourth magnetic block strips 1522 arranged in parallel and spaced apart, and a second magnetic channel 1523 is formed between the third magnetic block strips 1521 and the fourth magnetic block strips 1522; in the third magnetic block assembly 152 and the fourth magnetic block assembly 153, the magnetic field directions in the second magnetic channel 1523 are opposite and are respectively perpendicular to the upper and lower straight sides of the second rectangular coil 151.

[0050] The third magnetic block assembly 152 and the fourth magnetic block assembly 153 are distributed up and down, and the second magnetic channel 1523 in the third magnetic block assembly 152 and the second magnetic channel 1523 in the fourth magnetic block assembly 153 are connected up and down and connected; the second rectangular coil 151 is an upright rectangular structure, extending along the Y axis along the horizontal length direction. Since a very large force is not required when performing a keycap pulling test, and the Z axis moving path is short, the material thickness width of the second rectangular coil 151 in the X direction can be smaller to save space. The second rectangular coil 151 includes a first straight line segment 1511 located at the top and a second straight line segment 1512 located at the bottom and parallel to the first straight line segment 1511. The first straight line segment 1511 passes through the second magnetic channel 1523 in the third magnetic block assembly 15 in the Y direction, and the second straight line segment 1512 passes through the second magnetic channel 1523 in the fourth magnetic block assembly 153 in the Y direction.

[0051] The direction of the magnetic field in the second magnetic channel 1523 is set parallel to the X-axis direction.

[0052] The second mounting seat 14 includes a top mounting plate 141, a front mounting plate 142 and a rear mounting plate 143 arranged below the opposite sides of the top mounting plate 141 along the X-axis direction, and a bottom mounting plate 144 fixed below the front mounting plate 142 or the rear mounting plate 143, and a fifth mounting cavity (not marked in the figure) for mounting the third magnetic block assembly 152 and the fourth magnetic block assembly 153 is formed between the front mounting plate 142 and the rear mounting plate 143. Specifically, the third magnetic block strip 1521 in the third magnetic block assembly 152 and the fourth magnetic block strip 1522 in the fourth magnetic block assembly 153 are fixedly mounted on one side inner wall of the fifth mounting cavity in an up-and-down distribution, and the fourth magnetic block strip 1522 in the third magnetic block assembly 152 and the third magnetic block strip 1521 in the fourth magnetic block assembly 153 are fixedly mounted on the other opposite side inner wall of the fifth mounting cavity in an up-and-down distribution.

[0053] A third slide rail 145 extending along the Z axis is provided on the bottom mounting plate 144, and a third slider 161 cooperating with the third slide rail 145 is fixedly provided on the second movable frame 16, which is then slidably provided on the second mounting seat 14, and a tension spring 17 is also provided between the second mounting seat 14 and the second movable frame 16, and the second movable frame 16 is pulled by the tension spring 17.

[0054] The second rectangular coil 151 is fixedly mounted on the second movable frame 16, and the upper and lower straight sides are exposed. In one embodiment, the second movable frame 16 is provided with an inner circle positioning block 162 for positioning and clamping the inner circle of the second rectangular coil 151. In another embodiment, the left and right sides of the second rectangular coil 151 are fixedly mounted on the second movable frame 16, and can be fixed by gluing or by pressing with a pressing block.

[0055] The third magnetic block assembly 152 and the fourth magnetic block assembly 153 generate a horizontal magnetic field in the X direction. The current flowing in the Y direction in the second rectangular coil 151 will be subjected to an upward or downward Ampere force according to the left-hand rule, and the second movable frame 16 will move up and down.

[0056] A first motor controller 18 electrically connected to the X-axis driving module 12 is disposed on the first movable frame 13 , and a second motor controller (not shown) electrically connected to the Z-axis driving module 15 is disposed on the second mounting seat 14 .

[0057] The key cap detection module 2 includes a pressure sensor 21 fixed below the second movable frame 16 and a detection component 22 arranged at a sensing end of the pressure sensor 21 .

[0058] In one embodiment, the detection component 22 is a keycap puller hook component 221. The keycap puller hook component 221 can adopt a structure in the prior art, and its structure will not be described in detail in this embodiment.

[0059] In another embodiment, the detection component 22 is a keycap pressing component 222, which presses the keycap with a set pressure value, and can be suitable for keycap touch detection, normal pressing detection, etc.

[0060] In this embodiment, the first movable frame 13 is a three-dimensional frame structure as a whole, and the space occupied in the X direction is relatively narrow. The second mounting seat 14 and the second movable frame 16 are also arranged below the first movable frame 13 in a three-dimensional plate-like structure as a whole. The horizontal width of the two also only extends along the Y-axis direction, and the structural thickness in the X direction is relatively small. Therefore, the first movable frame 13, the second mounting seat 14, the Z-axis driving module 15 and the second movable frame 16 as a whole constitute a similar "three-dimensional thin plate structure" with a small thickness in the X direction and a certain length in the Y direction and the Z direction, which greatly saves space occupation. Multiple keycap detection modules 2 can be independently driven by arranging multiple "three-dimensional thin plate structures" along the X direction, effectively reducing the space occupation of the multi-head keycap detection mechanism, and the voice coil motor is formed by the magnetic block and the coil, which greatly improves the running speed, thereby improving the pull-out detection efficiency or the press detection efficiency.

[0061] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
