Description
Technical Field
[0001] The present invention relates to the technical field of screen detection, and particularly to a scribing device for the production of adjustable resistive screens. Background Art
[0002] Existing scribing devices for resistive screen production usually include a fixed frame, a workbench for placing the resistive screen, and a movable scribing mechanism.
[0003] Most of the existing scribing devices can only achieve single scribing tests. If it is necessary to detect the touch response performance of the resistive screen, special touch devices need to be used additionally, increasing the equipment cost. Moreover, usually, the scribing devices only perform linear tests on the screen. In real life, the user's finger often does not slide along the screen in a straight line. Most traditional devices only perform single linear tests and cannot truly simulate the actual operation of users to improve the authenticity of detection. Therefore, it is necessary to develop a scribing device for the production of adjustable resistive screens. Summary of the Invention

The left-right translation mechanism and the front-back translation mechanism are linked by sprockets and chains to achieve synchronous movement of the platform and the mounting frame, reducing independent drive.

[0046] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0047] Please refer to Figures 1-11 , which shows a schematic structural diagram of an embodiment of a scribing device for the production of an adjustable resistive touch screen of the present invention. Please refer to Figures 1-11 , and a detailed introduction to a scribing device for the production of an adjustable resistive touch screen will be given.
[0048] Embodiment 1, a scribing device for the production of an adjustable resistive touch screen, comprising:
[0049] A placement table 102 is horizontally reciprocally moved on the top of a frame 100 through a left-right translation mechanism 101. An inward concave placement groove 103 for placing a resistive touch screen is formed on the top of the placement table 102, and a clamping mechanism 104 for fixing the resistive touch screen is arranged on the inner side of the placement groove 103;
[0050] There are two fixing frames 200 in total, both of which are in a "冂" shape and are symmetrically fixed on the front and rear sides of the top of the frame 100. An installation frame 202 is reciprocally moved in the front and rear directions between the two fixing frames 200 above the placement groove 103 through a front-back translation mechanism 201;
[0051] A testing mechanism 300 is arranged inside the installation frame 202, including multiple vertical adjusting rods 301 and a "回" - shaped adjusting frame 302 fixed at the bottom of the adjusting rods 301. A vertical lifting rod 303 is slidably penetrated through the inner bottom wall of each adjusting frame 302 through a linear bearing. A rubber contact block 309 for contacting the resistive touch screen is arranged at the bottom end of each lifting rod 303. A transverse rotating rod 307 is rotatably penetrated through the side walls of all the adjusting frames 302 together, and the rotating rod 307 controls the positions of all the rubber contact blocks 309 through a transmission mechanism;
[0052] A distance adjusting mechanism 400 is arranged on the installation frame 202 for adjusting the distance between two adjacent adjusting rods 301;
[0053] A locking mechanism 500 is arranged on the testing mechanism 300 for controlling that when the installation frame 202 moves back and forth, the rotating rod 307 is in a locked state, and the rubber contact block 309 is in a continuous contact state with the surface of the resistive touch screen to perform a scribing test on the resistive touch screen;
[0054] The motion mechanism 600 is set between two fixed frames 200 to control the rotating rod 307 to rotate when the mounting frame 202 moves back and forth, and the rubber contact block 309 to be in intermittent contact with the surface of the resistive screen to perform touch test on the resistive screen.
[0055] In this embodiment, the left and right translation mechanism 101 on the frame 100 drives the platform 102 to move laterally, and cooperates with the front and rear translation mechanism 201 on the fixed frame 200 to drive the mounting frame 202 to move back and forth, which can expand the testing range.
[0056] The adjustment rod 301, adjustment frame 302 and rubber contact block 309 in the testing mechanism 300 can adjust the contact state through the transmission mechanism, and the distance adjustment mechanism 400 can adjust the distance between adjacent adjustment rods 301 to adapt to the testing requirements of resistive screens of different sizes.
[0057] The locking mechanism 500 and the motion mechanism 600 respectively realize the scribing test of continuous contact and the point contact test of intermittent contact, increasing the test function diversity of the device.
[0058] Example 2, based on Example 1: The left and right translation mechanism 101 includes a mounting port 105 opened on the frame 100. The inner sidewall of the mounting port 105 is rotatably provided with a first reciprocating lead screw 106 and two first guide slide rods 107 via bearing seats. The two first guide slide rods 107 are symmetrically arranged about the first reciprocating lead screw 106. A transmission plate 108 is slidably provided on the rod of the two first guide slide rods 107 via linear bearings. The top of the transmission plate 108 is fixedly connected to the bottom of the platform 102. The rod of the first reciprocating lead screw 106 moves through the sidewall of the transmission plate 108. The rotating first reciprocating lead screw 106 drives the transmission plate 108 to reciprocate along the axial direction of the first guide slide rods 107.
[0059] A worm gear 109 is fixedly installed at one end of the first reciprocating screw 106. A bracket 110 is symmetrically fixed at the bottom of the frame 100 near the worm gear 109. A drive rod 111 is rotatably connected between the two brackets 110 through a bearing sleeve. A worm 112 that meshes with the worm gear 109 is fixedly installed in the middle of the drive rod 111. A servo motor 113 is fixedly installed at the bottom of the frame 100. The output shaft of the servo motor 113 is fixedly connected to one end of the drive rod 111 through a coupling.
[0060] In this embodiment, the first reciprocating lead screw 106 cooperates with the first guide slide 107 to drive the stage 102 to reciprocate through the transmission plate 108. The lead screw transmission can improve the stability and accuracy of the lateral movement of the stage 102. The two first guide slides 107 are symmetrically arranged, which can reduce the shaking when the transmission plate 108 moves, and help maintain the stability of the resistive screen during the test. The servo motor 113 provides power, and it is convenient to adjust the moving speed of the stage 102 by controlling the motor speed to adapt to the needs of different test scenarios.
[0061] Example 3, based on Example 1: The clamping mechanism 104 includes screws 114 threaded through the left and right inner walls of the storage groove 103. The two screws 114 are arranged symmetrically in the left and right directions. One end of the two screws 114 located inside the storage groove 103 is rotatably provided with clamping plates 115 for clamping the left and right sides of the resistive screen through a bearing seat. The lower surface of the clamping plate 115 is in contact with the bottom surface of the inner cavity of the storage groove 103. A rubber anti-slip pad is provided on the side of the clamping plate 115 near the resistive screen. A first knob 116 is fixedly provided on the other end of the screws 114.
[0062] In this embodiment, the screw 114 drives the clamping plate 115 to move left and right, and the clamping distance can be adjusted according to the width of the resistive screen to adapt to resistive screens of different sizes; the rubber anti-slip pad on the clamping plate 115 can increase the friction with the resistive screen, reduce the wear on the surface of the resistive screen during clamping, and reduce the possibility of the resistive screen sliding during the test.
[0063] It should be noted that the clamping mechanism 104 can also be similarly arranged on the front and rear inner sides of the storage slot 103, so as to clamp the front and rear side walls of the resistive screen and further fix the resistive screen.
[0064] Example 4, based on Example 2: The front and rear translation mechanism 201 includes a second reciprocating screw 203 rotatably disposed between two fixed frames 200 via bearing sleeves and two second guide slide rods 204. The two second guide slide rods 204 are symmetrically arranged about the second reciprocating screw 203. The rods of the two second guide slide rods 204 slide through the top two sides of the mounting frame 202 respectively via linear bearings. The rod of the second reciprocating screw 203 moves through the middle position of the top of the mounting frame 202. The rotating second reciprocating screw 203 drives the mounting frame 202 to reciprocate along the axial direction of the second guide slide rods 204.
[0065] The rear end of the second reciprocating lead screw 203 and the rear end of the drive rod 111 are located behind the frame 100, and sprockets 205 are fixedly provided on them respectively. The two sprockets 205 are arranged on the same vertical plane and are linked by a chain 206.
[0066] In this embodiment, the second reciprocating lead screw 203 cooperates with the second guide slide 204 to drive the mounting frame 202 to move smoothly back and forth, improving the movement accuracy of the testing mechanism 300 in the front and back directions; the second reciprocating lead screw 203 and the drive rod 111 are linked through the sprocket 205 and the chain 206 to realize the coordinated movement of the left and right translation mechanism 101 and the front and back translation mechanism 201, reducing the use of independent drive components and simplifying the device structure;
[0067] It should be noted that the second reciprocating lead screw 203 and the drive rod 111 are linked through the sprocket 205 and the chain 206. That is, the left-right translational stage 102 and the front-back translational mounting bracket 202 share the same drive source, namely the servo motor 113. The two move in perpendicular directions and are linked, resulting in the motion trajectory of the testing mechanism 300 being a composite motion, that is, an oblique movement. This combination is because conventional scribing devices only perform linear tests on the screen, while in real life, users' fingers often do not slide along the screen in a straight line. Therefore, this composite oblique motion allows the testing mechanism to more realistically simulate the user's actual operation when performing sliding tests, improving the authenticity of the test.
[0068] Alternatively, the second reciprocating screw 203 and the drive rod 111 can be driven by motors instead of being linked by sprocket 205 and chain 206, so as to meet their respective driving needs, or the need for one to drive and the other to stop.
[0069] Example 5, based on Example 1: The transmission mechanism includes a circular plate 304 with an outer diameter larger than the lifting rod 303, fixed to the top of each lifting rod 303. A vertical spring 305 is fixed between the bottom of the circular plate 304 and the inner bottom wall of the adjusting frame 302. The outer side of the lifting rod 303 passes through the inner side of the spring 305. A semi-circular block 306 protrudes from the top of the circular plate 304. A disc cam 308 is provided on the inner side of each adjusting frame 302 on the rod body of the rotating rod 307. The lower surface of the disc cam 308 always abuts against the upper surface of the semi-circular block 306. Mounting blocks 310 are rotatably provided on the left and right sides of all the adjusting frames 302 via bearing sleeves.
[0070] A third guide slide rod 311 is provided on the left and right sides between the two fixed frames 200. The third guide slide rod 311 and the rotating rod 307 are vertically perpendicular and spaced apart. The axial direction of the third guide slide rod 311 is consistent with the movement direction of the mounting frame 202. The front and rear side walls of the two mounting blocks 310 are slidably penetrated by the rods of the two third guide slide rods 311 on the same side through linear bearings.
[0071] The portion of the rod body of the rotating rod 307 located between the two mounting blocks 310 is in the shape of a spline rod 312. The left and right side walls of each adjustment frame 302 are respectively provided with rotating cylinders 313 through bearing sleeves. The two sides of the disc cam 308 are respectively fixedly connected to the sides of the two adjacent rotating cylinders 313. The side walls of the rotating cylinders 313 and the disc cam 308 are both provided with spline slots 314 that are adapted to the spline rod 312. The inner side of the spline slot 314 slides laterally and fits against the rod body of the spline rod 312.
[0072] In this embodiment, the circular plate 304, the spring 305 and the semicircular block 306 cooperate to ensure the stability of the transmission by making the semicircular block 306 always in contact with the disc cam 308 when the disc cam 308 rotates through the elastic action of the spring 305.
[0073] The rotating rod 307 drives multiple disc cams 308 to rotate synchronously, which can simultaneously control the lifting and lowering of all rubber contact blocks 309, ensuring the consistency of the actions of multiple contact points;
[0074] The splined rod 312 slides into the splined slot 314 of the rotating drum 313, so that during the adjustment process, the rotating rod 307 can still drive the disc cam 308 to rotate without affecting the transmission function, thus improving the practicality of the adjustment mechanism 400.
[0075] Example 6, based on Example 1: The adjusting mechanism 400 includes vertical grooves 401 symmetrically opened on the left and right side walls of the inner cavity of the mounting frame 202. A lifting slide plate 402 is vertically slidably arranged between the two grooves 401. The front and rear side walls of the lifting slide plate 402 are provided with oblique guide openings 403 corresponding to the rear of each adjusting rod 301. The inclination angle of all the guide openings 403 increases gradually from the vertical central axis of the lifting slide plate 402 towards both sides. A guide block 404 is fixedly protruding from the middle of the rod body of each adjusting rod 301. The outer side wall of the rod body of each guide block 404 is in contact with the inner side wall of the corresponding guide opening 403 behind it. The inner side wall of the mounting frame 202 is symmetrically fixed with horizontal fourth guide slide rods 405. The left and right side walls of each adjusting rod 301 are slidably penetrated by the rod bodies of two fourth guide slide rods 405 through linear bearings.
[0076] The mounting bracket 202 has a vertical opening 406 in the middle of its rear side wall. The lifting slide plate 402 has a protrusion 407 fixedly installed in the middle of its rear side wall. The protrusion 407 is spaced through the opening 406 and protrudes from the rear of the mounting bracket 202. The mounting bracket 202 has mounting plates 408 fixedly installed vertically and vertically in the middle of its rear side wall. A vertical threaded post 409 is rotatably installed between the two mounting plates 408 through a bearing sleeve. The rod of the threaded post 409 is screwed through the protrusion 407. A second knob 410 is fixedly installed at the lower end of the threaded post 409.
[0077] In this embodiment, the guide bevel 403 of the lifting slide plate 402 cooperates with the guide block 404 of the adjusting rod 301. By the vertical movement of the lifting slide plate 402, the lateral spacing of multiple adjusting rods 301 can be adjusted simultaneously, making the operation simple.
[0078] The fourth guide slide 405 guides the adjusting rod 301, reducing shaking during the adjustment process. The threaded column 409 cooperates with the second knob 410 to precisely control the position of the lifting slide plate 402 and improve the adjustment accuracy.
[0079] Example 7, based on Example 5: The locking mechanism 500 includes a connecting frame 501 fixed to the right side of the right mounting block 310. The connecting frame 501 is inverted "L" shape and its right side wall is rotatably penetrated by the rod body of the rotating rod 307. A fixing block 502 is fixedly installed on the right side wall of the connecting frame 501 above the rotating rod 307. A vertical locking screw 503 is screwed through the fixing block 502. Locking holes 504 are equally spaced around the outer side of the rod body of the rotating rod 307 with its own horizontal axis as the center. The lower end of the locking screw 503 is used to insert into one of the locking holes 504. A third knob 505 is fixedly installed on the right end of the rotating rod 307.
[0080] In this embodiment, the locking screw 503 is inserted into the locking hole 504 to fix the position of the rotating rod 307, so that the rubber contact block 309 maintains continuous contact with the resistive screen when the mounting bracket 202 moves, ensuring the continuity of the scribing trajectory;
[0081] It should be noted that there are multiple locking holes 504 with small spacing, which ensures that the rotating rod 307 can be locked at as many angles as possible. In addition, the rubber contact block 309 has a certain degree of elasticity, so that the rotating rod 307 can maintain contact with the resistive screen when it is fixed.
[0082] Example 8, based on Example 5: The motion mechanism 600 includes a gear 601 fixed to the right side of the rotating rod 307. The two fixing brackets 200 are respectively provided with recessed slots 602 on opposite sides and right sides. A retaining plate 603 is inserted horizontally between the two slots 602. The gear 601 is located directly above the retaining plate 603, and a rack 604 that meshes with the gear 601 is provided on the top of the retaining plate 603.
[0083] The furthest distance between the two card slots 602 is equal to the length of the card plate 603. The upper and lower walls of the card slots 602 are respectively attached to the upper and lower walls of the card plate 603. The right side walls of the two fixing brackets 200 are rotatably provided with baffles 606 via rotating shafts 605. The distance between the left side of the baffle 606 and the left side of the card slot 602 is the same as the width of the card plate 603.
[0084] In this embodiment, when the mounting bracket 202 moves back and forth, it drives the rotating rod 307 to rotate. Through the meshing of the gear 601 and rack 604 in the transmission mechanism, the rubber contact block 309 makes intermittent contact with the resistive screen, thus meeting the requirements of touch test.
[0085] The card plate 603 is fixed by the card slot 602 and the baffle 606, which facilitates installation and disassembly. The point touch function can be selected to be enabled according to the test requirements, which increases the flexibility of the device.

In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
