Description

[Technical Field]

[0001] This invention belongs to the field of keyboard testing technology, and in particular relates to a 12-head high-efficiency keycap press test module. [Background Technology]

[0002] A keyboard is generally assembled from an aluminum substrate, a circuit board, a scissor-switch support frame, and keycaps. After the keyboard is manufactured, the spring rebound feel of the keys needs to be tested. There should be no key collapse or insufficient rebound, and the rebound feel must meet the set requirements.

[0003] In 2016, our company developed an automatic testing machine for the feel and function of laptop keyboards, patent number CN201621160936.1. Its press test head assembly includes six sensor press components corresponding to the number of keyboard rows, and a driving component that corresponds to each sensor press component and drives the sensor press components to adjust their position along the long side for precise pressing. However, all the driving components are arranged side-by-side on one side, making the overall structure of the press test head assembly quite crowded. This places high demands on the structural layout and presents certain manufacturing difficulties. Furthermore, it can only test one keyboard at a time, resulting in low testing efficiency. Also, of the six press components, only the two outermost press heads can move laterally to adjust the spacing, limiting its applicability.

[0004] Therefore, it is necessary to provide a new 12-head high-efficiency keycap press test module to solve the above-mentioned technical problems. [Summary of the Invention]

[0005] The main objective of this invention is to provide a 12-head high-efficiency keycap press test module with a compact structure and reasonable layout. It can simultaneously perform independent press rebound tests on 12 keycaps, greatly improving the testing efficiency of keycap press rebound tests.

[0006] The present invention achieves the above objective through the following technical solution: a 12-head high-efficiency keycap pressing test module, comprising a support plate and six sets of module units disposed on the support plate, the six sets of module units being arranged side by side and staggered, each module unit comprising a support base, a first motor and a second motor fixed at the same end of the support base, a first pressing test head and a second pressing test head movably disposed on the support base along the X-axis, a first synchronous belt driven by the first motor to perform cyclic movement, and a second synchronous belt driven by the second motor to perform cyclic movement; the first synchronous belt is distributed parallel to the bottom of the second synchronous belt, the first pressing test head is fixedly connected to one side of the first synchronous belt, and the second pressing test head is fixedly connected to one side of the second synchronous belt.

[0007] Furthermore, the rotating end of the first motor is provided with a first synchronous pulley, the rotating end of the second motor is provided with a second synchronous pulley, and the other end of the support base is provided with a third synchronous pulley and a fourth synchronous pulley. The third synchronous pulley and the fourth synchronous pulley are arranged coaxially. The first motor and the second motor, the first synchronous pulley and the second synchronous pulley are arranged along the X-axis and have a stepped height difference in the Z-axis direction.

[0008] Furthermore, the first synchronous belt is wound around the first synchronous pulley and the third synchronous pulley, and the second synchronous belt is wound around the second synchronous pulley and the fourth synchronous pulley.

[0009] Furthermore, the support base is provided with a first slide rail arranged along the X-axis, and the first pressing test head and the second pressing test head are suspended on the first slide rail by a first slider; the first slide rails in adjacent module units are staggered vertically.

[0010] Furthermore, both the first and second press test heads include a pressure sensor and a pressing rod disposed at the sensing end of the pressure sensor; the first and second press test heads pass through the first and second synchronous belts sequentially from top to bottom.

[0011] Furthermore, two adjacent sets of module units A and B are arranged alternately opposite each other; in module unit A, the first motor and the second motor are arranged at one end of the support base, and in module unit B, the first motor and the second motor are arranged at the other end of the support base; and one end of module unit B extends out of the corresponding end of module unit A, and the other end of module unit A extends out of the corresponding end of module unit B.

[0012] Furthermore, five of the six module units are movably mounted on the support plate along the Y-axis, while the remaining module unit is fixedly mounted; the lower surface of the support plate is provided with at least two pairs of second slide rails along the Y-axis, and the support seats of the five module units are suspended on the second slide rails by second sliders.

[0013] Furthermore, the two outermost groups of module units are each driven individually by the first driving unit to move along the Y-axis; the three adjacent groups of module units in the middle are driven by the same second driving unit to move along the Y-axis.

[0014] Furthermore, the first drive unit includes a second motor fixed on the support plate, a first lead screw driven by the second motor to rotate, a first nut sleeve that cooperates with the first lead screw to achieve linear motion, and a first connecting plate fixedly connected to the first nut sleeve.

Detailed Implementation Methods

[0029] Example 1:

[0030] Please refer to Figures 1-6 This embodiment is a 12-head high-efficiency keycap pressing test module 100, which includes a support plate 1 and six sets of module units 2 disposed on the support plate 1. The six sets of module units 2 are arranged side by side and staggered. The two outermost sets of module units 2 are driven by the first driving unit 3 to move along the Y-axis individually. The three adjacent sets of module units 2 in the middle are driven by the same second driving unit 4 to move along the Y-axis. The remaining set of module units 2 is fixed.

[0031] Module unit 2 includes a support base 21, a first motor 22 and a second motor 23 fixed to the same end of the support base 21, a first pressing test head 26 and a second pressing test head 27 movably mounted on the support base 21 along the X-axis, a first synchronous belt 24 driven by the first motor 22 to perform cyclical motion, and a second synchronous belt 25 driven by the second motor 23 to perform cyclical motion. The first synchronous belt 24 and the second synchronous belt 25 are parallel to each other, with the second synchronous belt 25 located below the first synchronous belt 24. The first pressing test head 26 is fixedly connected to one side of the first synchronous belt 24, and the second pressing test head 27 is fixedly connected to one side of the second synchronous belt 25. The first motor 22 drives the first synchronous belt 24 to perform cyclical motion, thereby driving the first pressing test head 26 to move along the X-axis. Similarly, the second motor 23 drives the second synchronous belt 25 to perform cyclical motion, thereby driving the second pressing test head 27 to move along the X-axis.

[0032] The rotating end of the first motor 22 is provided with a first synchronous pulley 28, the rotating end of the second motor 23 is provided with a second synchronous pulley 29, and the other end of the support base 21 is provided with a third synchronous pulley 210 and a fourth synchronous pulley 211. The third synchronous pulley 210 and the fourth synchronous pulley 211 are arranged coaxially. The first synchronous belt 24 is wound around the first synchronous pulley 28 and the third synchronous pulley 210, and the second synchronous belt 25 is wound around the second synchronous pulley 29 and the fourth synchronous pulley 211. The first motor 22 and the second motor 23, the first synchronous pulley 28 and the second synchronous pulley 29 are arranged along the X-axis and have a stepped height difference in the Z-axis direction, so that the first synchronous belt 24 and the second synchronous belt 25 can be distributed in parallel vertically.

[0033] The support base 21 is provided with a first slide rail 212 arranged along the X-axis, and the first pressing test head 26 and the second pressing test head 27 are suspended on the first slide rail 212 by the first slider 213.

[0034] The first press test head 26 and the second press test head 27 each include a pressure sensor 261 and a press rod 262 disposed at the sensing end of the pressure sensor 261. The structure of the press test head can be referenced from the specific structure in the company's existing patents. The first press test head 26 and the second press test head 27 pass through the first synchronous belt 24 and the second synchronous belt 25 sequentially from top to bottom.

[0035] Through the structural design of module unit 2, the two pressing test heads are arranged independently in the X-axis within a narrow width range, and the two pressing test heads do not interfere with each other; the first motor 22 and the second motor 23 in each module unit 2 are distributed along the X-axis, and the two do not interfere with each other and are arranged in a compact manner.

[0036] Two adjacent sets of module units 2 are arranged in an alternating manner. For example, in module unit A, the first motor 22 and the second motor 23 are located at one end of the support base 21, and in module unit B, the first motor 22 and the second motor 23 are located at the other end of the support base 21; and one end of module unit B extends out of the corresponding end of module unit A, and the other end of module unit A extends out of the corresponding end of module unit B. The above-described structure allows the 12 motors in the six module units 2 to be compactly arranged in the Y-axis direction. The 12 motors that drive the 12 pressing test heads to move independently in the X-axis direction are divided into six groups. In the first, third, and fifth groups, the first motor 22 and the second motor 23 are arranged side by side at one end of the test module. In the second, fourth, and sixth groups, the first motor 22 and the second motor 23 are arranged side by side at the other end of the test module. The protruding design at the ends of adjacent module units allows the motors in the protruding module unit 2 to have more layout space in the Y-axis direction, which is more conducive to reducing the distance between the support bases 21 in the two module units 2 and reducing the distance between the six adjacent first pressing test heads 26 or the six second pressing test heads 27.

[0037] In order to minimize the spacing between the press test heads and meet the synchronous detection of the corresponding six rows of keycaps, in this embodiment, the support base 21 is arranged side by side. The first press test head 26 and the second press test head 27 are suspended on the first slide rail 212 of the support base 21 by the first slider 213. In order to solve the problem of mutual interference between adjacent first sliders 213, in this embodiment, the first slide rails 212 in adjacent module units 2 are staggered vertically.

[0038] The first drive unit 3 includes a third motor 31 fixed on the support plate 1, a first lead screw 32 driven by the third motor 31 to rotate, a first nut sleeve 33 cooperating with the first lead screw 32 to achieve linear motion, and a first connecting plate 34 fixedly connected to the first nut sleeve 33. The first connecting plate 34 is fixedly connected to the support seat 21 in the module unit 2. The first lead screw 32 is driven to rotate by the third motor 31, thereby driving the support seat 21 to move along the Y-axis on the support plate 1. Five of the six module units 2 are movably arranged on the support plate 1 along the Y-axis. The lower surface of the support plate 1 is provided with two pairs of second slide rails 11 arranged along the Y-axis. The support seats 21 in the five module units 2 are suspended on the second slide rails 11 by second sliders 214. The third motors 31 in the two first drive units 3 are distributed opposite to each other.

[0039] The second drive unit 4 includes a fourth motor 41 fixed on the support plate 1, a second lead screw 42 driven by the fourth motor 41 to rotate, a second nut sleeve 43 cooperating with the second lead screw 42 to achieve linear motion, and a second connecting plate 44 fixedly connected to the second nut sleeve 43 and movably disposed on the support plate 1 along the X-axis. The second connecting plate 44 is provided with a plurality of guide grooves 441. In the three sets of module units 2 driven by the second drive unit 4, each module unit 2 has a support seat 21 provided with a cam 45 cooperating with the guide groove 441 to achieve transmission. The movement of the second connecting plate 44 along the X-axis enables the three adjacent support seats 21 to move synchronously at equal intervals along the Y-axis. In this embodiment, the support plate 1 is provided with a pair of third slide rails 12 disposed along the X-axis, and the second connecting plate 44 is movably disposed on the third slide rails 12 by a third slider (not shown in the figure).

[0040] This embodiment discloses a 12-head high-efficiency keycap pressing test module 100. When testing the pressing and rebound feel of keycaps on a keyboard, the first drive unit 3 and the second drive unit 4 adjust the spacing of six sets of module units 2 in the Y-axis direction according to the keycap distribution of the keyboard, so that each set of module units 2 can be aligned with each row of keycaps. The pressing test action of each row of keycaps is completed by two pressing test heads in each set of module units 2. The first pressing test heads 26 in the six sets of module units 2 are aligned side by side with the keycaps at one end of the keyboard. At the same time, the second pressing test heads 27 in the six sets of module units 2 are aligned side by side with the set keycaps in the middle of the keyboard. Then, all the first motors 22 and the second motors 23 are started, driving all the first pressing test heads 26 and the second pressing test heads 27 to move synchronously and in the same direction, and performing pressing tests on the keycaps one by one.

[0041] This embodiment presents a 12-head high-efficiency keycap pressing test module 100, which consists of six module units corresponding to the six rows of keycaps on the keyboard. Each module unit has two pressing test heads, which simultaneously test one row of keycaps. A total of 12 pressing test heads test all keycaps at the same time, greatly improving the testing efficiency of keycap tactile feedback pressing. The test module has a compact layout and a relatively symmetrical overall structure, which keeps the center of gravity in the center, improving the stability and reliability of drive transfer.

[0042] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
