Description

Technical Field

[0001] This invention belongs to the field of signal processing device technology, specifically a high-precision touch signal acquisition and processing device. Background Technology

[0002] Touch signal acquisition and processing devices are core components of human-computer interaction systems and are widely used in industrial control, smart terminals, medical equipment and other fields.

With the continuous development of touch technology, higher requirements are placed on the integration, stability and maintainability of signal acquisition and processing devices. Related equipment usually needs to have a reliable mechanical fixing structure, convenient assembly method and good environmental adaptability to meet the needs of use under complex working conditions.

[0003] However, existing touch signal acquisition and processing devices have many shortcomings in practical applications: on the one hand, the acquisition processors are mostly fixed with bolts or snap-fit ​​installations, making the disassembly and assembly process cumbersome and not conducive to the rapid maintenance and replacement of the equipment; on the other hand, the device shell and internal components are usually rigidly connected, lacking an effective shock absorption and buffering mechanism during movement or transportation, and external vibrations and shocks can easily be directly transmitted to the precision electronic components, resulting in a decrease in signal acquisition accuracy or even hardware damage; in addition, the cover plate of the existing device is independent of the internal load-bearing structure, and the acquisition processor still needs to be manually removed and placed after opening the cover plate, which is not very convenient to operate and the overall work efficiency needs to be improved.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] Please see Figures 1-6 As shown, the present invention provides a technical solution: a high-precision touch signal acquisition and processing device, including a housing 1, a storage plate 2, a clamping mechanism 3, and an acquisition processor 4;

[0032] Storage plate 2 is disposed inside outer casing 1;

[0033] The clamping mechanism 3 is installed at the bottom of the storage plate 2 for quick and easy installation of the acquisition processor 4, while the acquisition processor 4 is placed on the storage plate 2.

[0034] The clamping mechanism 3 includes a micro motor 31, a reciprocating lead screw 32, a threaded block 33, a vertical rod 34, and a clamping plate 35;

[0035] The micro motor 31 is fixed to the bottom of the storage plate 2, and the reciprocating screw 32 is fixed to the output end of the micro motor 31. There are two sets of threaded blocks 33, and the two sets of threaded blocks 33 are respectively threaded and connected to both ends of the reciprocating screw 32. The vertical rod 34 is fixed to the threaded block 33, and the clamping plate 35 is fixed to the end of the vertical rod 34 away from the threaded block 33, which is used to clamp the acquisition processor 4.

[0036] Further: Two sets of threaded blocks 33 are installed on the left and right turns of the reciprocating screw 32. At the same time, when the data acquisition processor 4 is placed on the storage plate 2, the micro motor 31 drives the reciprocating screw 32 to rotate, so that the two threaded blocks 33 drive the clamping plate 35 to move towards or away from each other, thereby realizing the rapid clamping or loosening of the data acquisition processor 4.

[0037] In this embodiment, specifically: a side plate 5 is fixedly connected to the bottom of the storage plate 2 to support the rotation of the reciprocating lead screw 32, and the reciprocating lead screw 32 is rotatably connected to the side plate 5.

[0038] Further: A circular bearing hole is provided on the side of the side plate 5, and a rolling bearing is installed in the hole. One end of the reciprocating screw 32 is inserted into the inner ring of the bearing, so that the reciprocating screw 32 can rotate freely.

[0039] In this embodiment, specifically: a square opening 6 is provided on one side of the outer shell 1, and a cover plate 7 is rotatably connected to the outer shell 1. An opening and closing lifting mechanism 8 is installed in the square opening 6, which is used to open the cover plate 7 and drive the storage plate 2 to rise. The opening and closing lifting mechanism 8 includes a gear 81, a rack 82, and a slide rod 83. The gear 81 is fixed to the pin shaft of the cover plate 7, the rack 82 is meshed with the gear 81, and the slide rod 83 is fixed to the end of the rack 82 away from the gear 81. The end of the slide rod 83 away from the rack 82 is fixed to the storage plate 2, which is used to drive the acquisition processor 4 on the storage plate 2 to rise and fall.

[0040] Further: When the operator opens the cover 7 upwards, the gear 81 drives the rack 82 to move upwards, and then the slide bar 83 lifts the storage plate 2 and the acquisition processor 4 placed on it out of the housing 1 for easy maintenance or replacement.

[0041] In this embodiment, specifically: the opening and closing lifting mechanism 8 also includes a data acquisition processor 4, and the guide port 84 passes through the sliding connecting rod 83 to limit and guide the movement of the sliding rod 83.

[0042] Furthermore, the guide opening 84 is a long strip-shaped through groove through which the rod of the slide rod 83 passes and slides. The width of the guide opening 84 is equal to the diameter of the slide rod 83, thereby strictly limiting the slide rod 83 to move only laterally and preventing it from swinging back and forth or left and right during the lifting process.

[0043] In this embodiment, specifically: a shock-absorbing mechanism 9 is provided inside the outer shell 1 to reduce shock when the carrying and processing device is moved. The shock-absorbing mechanism 9 includes a damping rod 91, a connecting block 92, a return spring 93, and a drive link 94. There are two sets of damping rods 91, which are respectively fixed to both sides of the outer shell 1. The connecting block 92 is fixed to the end of the damping rod 91 away from the outer shell 1. The return spring 93 is sleeved on the damping rod 91, and both ends of the return spring 93 are respectively fixed to the outer shell 1 and the connecting block 92. One end of the drive link 94 is hinged to the connecting block 92, and the end of the drive link 94 away from the connecting block 92 is hinged to the bottom of the storage plate 2.

[0044] Further: When the equipment is subjected to vertical vibration, the storage plate 2 floats up and down, the drive link 94 pushes the connecting block 92 to move horizontally, and at the same time the damping rod 91 and the return spring 93 jointly absorb and attenuate the vibration energy.

[0045] In this embodiment, specifically: the shock absorption mechanism 9 further includes a guide groove 95 and a guide block 96. The guide groove 95 is disposed at the bottom of the outer shell 1. The guide groove 95 is limited and guided by the internal sliding guide block 96. At the same time, the end of the guide block 96 away from the guide groove 95 is fixed to the bottom of the connecting block 92.

[0046] Furthermore, when the connecting block 92 moves horizontally due to vibration damping, the guide block 96 slides synchronously along the guide groove 95, thereby providing precise linear guidance for the movement of the connecting block 92 and preventing the connecting block 92 from rotating or getting stuck.

[0047] In this embodiment, specifically: a plug rod 10 is slidably connected through one side of the outer shell 1 for insertion into a socket positioned on one side of the storage plate 2. A pull rod 11 is fixedly connected to the end of the plug rod 10 away from the storage plate 2. At the same time, a first spring 12 is sleeved on the plug rod 10, and the two ends of the first spring 12 are respectively fixedly connected to the pull rod 11 and the outer shell 1. A telescopic rod 13 is fixedly connected to the pull rod 11, and the end of the telescopic rod 13 away from the pull rod 11 is fixedly connected to the outer shell 1.

[0048] Further: When in use, pull the lever 11 outward to make the insert 10 exit the insertion hole. After releasing, it will automatically insert under the action of spring force to lock the position of the storage plate 2. The telescopic rod 13 ensures that the lever 11 remains horizontal and does not deflect when it is pulled out.

[0049] In this embodiment, specifically: the storage plate 2 is provided with a first sliding groove 14, and the first sliding groove 14 passes through the sliding connecting vertical rod 34, which is used to limit and guide the movement of the threaded block 33. The outer shell 1 is provided with a second sliding groove 15 on one side, and the second sliding groove 15 limits and guides the lifting and lowering of the storage plate 2 through the internal sliding guide rod 16. At the same time, the end of the guide rod 16 away from the second sliding groove 15 is fixed to the storage plate 2.

[0050] Further: When the storage plate 2 is raised or lowered, the guide rod 16 slides up and down along the second slide groove 15 to ensure that the storage plate 2 always remains horizontal and will not tilt.

[0051] In this embodiment, specifically: the storage plate 2 is provided with a limiting groove 17, and the limiting groove 17 limits and guides the movement of the clamping plate 35 through the internal sliding pad 18, while the end of the pad 18 away from the limiting groove 17 is fixed to the bottom of the clamping plate 35.

[0052] Furthermore, when the clamping plate 35 moves under the drive of the threaded block 33, the pad block 18 moves linearly along the limiting groove 17, thereby preventing the clamping plate 35 from tilting or rotating due to uneven force, and ensuring that the clamping surface is completely in contact with the side wall of the acquisition processor 4.

[0053] In this embodiment, specifically: the outer casing 1 is provided with ventilation holes 19 for ventilation and heat dissipation.

[0054] Furthermore, the ventilation holes 19 are provided in several groups, and the several groups of ventilation holes 19 are evenly distributed on the outer shell 1.

[0055] Working principle or structural principle: When the data acquisition processor 4 needs to be installed, the micro motor 31 of the clamping mechanism 3 is started, and its output end drives the reciprocating screw 32 to rotate. With the support of the side plate 5, the reciprocating screw 32 drives the threaded blocks 33 with threads connected at both ends to move towards each other along the first slide groove 14. The threaded blocks 33 drive the clamping plate 35 and the pad block 18 to move synchronously closer along the limiting groove 17 through the vertical rod 34, thereby quickly fixing and clamping the data acquisition processor 4 placed on the storage plate 2. When the data acquisition processor 4 needs to be removed, the cover plate 7 is opened. The gear 81 on the pin shaft of the cover plate 7 rotates and meshes with the rack 82, driving the rack 82 and the slide rod 83 to rise along the guide port 84. The slide bar 83 pushes the storage plate 2 to rise synchronously under the limiting guidance of the second slide groove 15 and the guide rod 16, so that the acquisition processor 4 rises out of the outer shell 1 for easy access. At the same time, the insertion rod 10 can be inserted and positioned in the insertion hole of the storage plate 2 under the action of the first spring 12, so as to fix the storage plate 2 when it rises to the top. During the movement and carrying process, the damping rod 91 of the shock absorption mechanism 9 and the return spring 93 work together to buffer the vibration of the outer shell 1 through the connecting block 92 and the drive connecting rod 94. At the same time, the guide groove 95 and the guide block 96 limit and guide the movement of the connecting block 92 to ensure the stability of the internal components. Meanwhile, the ventilation hole 19 ensures the heat dissipation requirements of the acquisition processor 4 when it is working.
