Description

Technical Field

[0001] This utility model relates to the field of force measurement and control instrument technology, and in particular to a weight acquisition and equalization device with multi-support bearing. Background Technology

[0002] Multiple sensors at different locations on the weighing platform are responsible for synchronously collecting dispersed weight data. The force control instrument is the core of data processing. The sensors transmit the raw signals to the instrument through connecting lines. The instrument is calibrated, integrated and analyzed by the equalization algorithm, and outputs accurate summary data. The two need to have a stable data connection to jointly achieve comprehensive and accurate collection of weight at multiple support points.

[0003] In multi-point weight acquisition scenarios, the weighing platform needs to cover different load-bearing areas with multiple sensors to ensure the comprehensiveness of data acquisition. Each sensor needs to establish a data connection with the force control instrument through an independent connection cable, which leads to a significant increase in the number of connection cables. Traditional connection methods lack effective fixing and storage structures, and the cables are prone to scattering and tangling, which not only takes up space and affects operation, but may also cause poor contact of the lines due to pulling and bending.

[0004] Meanwhile, multi-cable connections are prone to signal interference and unstable transmission. Furthermore, traditional connectors often use screws or simple plug-ins, making assembly and disassembly cumbersome. Later maintenance involves time-consuming and labor-intensive cable management and interface inspection, resulting in the force control instrument's inability to accurately integrate sensor data, affecting the accuracy and reliability of weight acquisition and hindering production efficiency. Therefore, those skilled in the art have provided a multi-support weight acquisition and equalization device to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a weight acquisition and balancing device with multi-support bearing, comprising,

[0008] The force control instrument includes a display panel at the front end of the force control instrument, a closed cover at the front of the force control instrument, a connecting wire at the rear of the force control instrument for connecting to the load cell, and a connector at one end of the connecting wire that is plugged into the interface at the rear end of the force control instrument.

[0009] The locking structure includes multiple symmetrically distributed mounting frames fixed to the rear end of the force control instrument, a connecting rod located inside one side of the mounting frame, a rotating shaft passing through the connecting rod and rotatably mounted inside the mounting frame at both ends, a torsion spring sleeved on the outside of the rotating shaft and connected to the connecting rod and the mounting frame at both ends, a clamp located at the lower end of the connecting rod and clamped to the outside of the connector, a pressure sleeve located on the inner wall of the outer side of the connecting rod with an increasing radius from top to bottom, a pressure handle located at the upper end of the pressure sleeve, two sliders symmetrically distributed at the rear end of the pressure sleeve, a connecting block located between the two sliders, a spring located at the upper end of the connecting block, and a top block located at the upper end of the spring and connected to the rear end of the force control instrument.

[0010] as well as;

[0011] The storage structure includes a wiring frame fixed to the rear of the force control instrument.

[0012] Furthermore, a positioning cylinder is provided at the lower end of the top block, and a spring connected to the connecting block at the lower end of the positioning cylinder is slidably inserted inside the lower end of the positioning cylinder. Both the positioning cylinder and the positioning rod are located inside the spring.

[0013] Specifically, the positioning cylinder and the positioning rod are slidably installed to limit the extension and retraction of the spring and prevent it from shifting outward during the extension and retraction process.

[0014] Furthermore, a ball bearing is rotatably installed inside the upper end of the connecting rod, a slide block two is provided on the outer wall of the rear side of the force measuring control instrument, and a rubber pad is provided on the inner wall of the jacket.

[0015] Specifically, when the pressure sleeve compresses the connecting rod, the frictional resistance is reduced by the ball bearings, and the second slider is slidably supported by the second slide block, so that the longitudinal movement of the pressure sleeve is guided and the movement is stable. The rubber pad reduces the friction of clamping and improves the clamping tightness.

[0016] Furthermore, both ends of the force measuring control instrument are provided with brackets with slots inside, both sides of the front end of the force measuring control instrument are provided with slide blocks, the rear end of the closed cover is provided with a slider that is slidably installed inside the slide blocks, and the upper side of the force measuring control instrument is provided with a top plate that is magnetically connected to the closed cover.

[0017] Specifically, the bracket is used for the installation of force control instruments. It is used to install fixed parts through the slot. The slider slides on the outer wall of the slide block to provide longitudinal sliding support for the closed cover. When the closed cover is in contact with the top plate, it is magnetically positioned for simple fixation.

[0018] Furthermore, a rear groove is provided inside the wiring frame, and a section of the connecting line passes through the rear groove and is located between the wiring frame and the rear side of the force control instrument;

[0019] Specifically, excess connecting wires are collected at the back of the wiring frame via the rear slot, preventing them from being scattered outside.

[0020] Furthermore, the rear end of the force measuring control instrument is provided with symmetrically distributed side blocks, one end of the side block is provided with a second spring, one end of the second spring is provided with a clamping block for holding the connecting wire, the front end of the clamping block is provided with a handle, and the second spring is slidably installed with a second positioning cylinder and a second positioning rod, one end of which is connected to the side block and the clamping block and slidably inserted into the second spring.

[0021] Specifically, the grip handle facilitates the application of pulling force to the clamping block, causing the second spring to be compressed. When the second spring extends or retracts, the second positioning rod and the second positioning cylinder are slidably installed to prevent the second spring from shifting outwards. The clamping block clamps and fixes the connecting wire stored at the rear of the wiring frame.

[0022] 2. Beneficial effects

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] In this invention, multiple weighing sensors are connected to a force control instrument via connecting cables. The weighing sensors transmit weighing data from different positions to the force control instrument for processing. Precise data balancing processing enables stable and accurate weight acquisition. Sensor deviations are calibrated using weights and weightless calibration. Finally, the data is aggregated and output as a precise weight value. After the connector of the connecting cable is connected to the force control instrument, the connector is clamped by a torsion spring torsional elastic support, ensuring a stable data connection between the weighing sensors and the force control instrument and guaranteeing the stability of the data balancing processing.

[0025] Simultaneously, the pressure sleeve is pressed down, and the connecting rod is squeezed by the pressure sleeve being narrow at the top and wide at the bottom, thereby realizing the expansion of the clamp. The pressure sleeve can be pressed down before pulling out the connector. After the pressure sleeve is used, it is automatically lifted and reset by the elastic support. At the same time, after the connecting rod is released from longitudinal compression, the torsional elastic support of the rotating shaft and torsion spring drives the clamp to automatically clamp the connector. This facilitates the connection and disconnection of the force control instrument and the load cell. It is convenient and flexible to use, and the fixing and contact fixing are time-saving and simple.

[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] Please see Figure 1-6 As shown, this embodiment is a multi-support weight acquisition and balancing device, including,

[0044] The force control instrument 100 includes a display panel 106 at the front end of the force control instrument 100, a closed cover 103 located at the front side of the force control instrument 100, a connecting line 107 located at the rear side of the force control instrument 100 for connecting to a weight sensor, and a connector 108 located at one end of the connecting line 107 and plugged into the rear interface of the force control instrument 100.

[0045] The force measuring control instrument 100 has brackets 101 with slots inside at both ends. The front sides of the force measuring control instrument 100 have slides 104. The rear end of the closed cover 103 has a slider 105 that is slidably installed inside the slides 104. The upper side of the force measuring control instrument 100 has a top plate 102 that is magnetically connected to the closed cover 103.

[0046] The locking structure 200 includes multiple symmetrically distributed mounting frames 210 fixed to the rear end of the force control instrument 100, a connecting rod 211 located inside one side of the mounting frame 210, a rotating shaft 213 passing through the connecting rod 211 and rotatably mounted inside the mounting frame 210 at both ends, a torsion spring 216 sleeved on the outside of the rotating shaft 213 and connected to the connecting rod 211 and the mounting frame 210 at both ends, a clamping sleeve 214 located at the lower end of the connecting rod 211 and clamped on the outside of the connector 108, a pressure sleeve 209 located on the inner wall of the outer side above the connecting rod 211 with an increasing radius from top to bottom, a pressure handle 205 located at the upper end of the pressure sleeve 209, two sliders 207 symmetrically distributed at the rear end of the pressure sleeve 209, a connecting block 206 located between the two sliders 207, a spring 203 located at the upper end of the connecting block 206, and a top block 202 located at the upper end of the spring 203 and connected to the rear end of the force control instrument 100.

[0047] A positioning cylinder 201 is provided at the lower end of the top block 202. A spring 203, whose lower end is connected to the connecting block 206, is slidably inserted inside the lower end of the positioning cylinder 201. Both the positioning cylinder 201 and the positioning rod 204 are located inside the spring 203.

[0048] A ball bearing 212 is rotatably installed inside the upper end of the connecting rod 211. A slide block 208 is provided on the outer wall of the rear side of the force measuring control instrument 100 and is slidably installed with the slider 207. Rubber pads 215 are provided on the inner wall of the sleeve 214.

[0049] as well as;

[0050] The storage structure 300 includes a wiring frame 301 fixed to the rear side of the force control instrument 100;

[0051] The wiring frame 301 has a rear groove 303 inside, and a section of the connecting line 107 passes through the rear groove 303 and is located between the wiring frame 301 and the rear side of the force control instrument 100.

[0052] The force measuring control instrument 100 has symmetrically distributed side blocks 307 at its rear end. A second spring 304 is provided at one end of the side block 307. A clamping block 308 for holding the storage connecting line 107 is provided at one end of the second spring 304. A handle 302 is provided at the front end of the clamping block 308. A positioning cylinder 306 and a positioning rod 305 are slidably installed inside the second spring 304, with their opposite ends connected to the side block 307 and the clamping block 308 and slidably inserted.

[0053] Based on the implementation steps of Embodiment 1: the device is fixed to the production bench or testing area through the slots of the brackets 101 at both ends of the force control instrument 100 to ensure that the instrument is horizontal and stable. The slider 105 at the rear end of the sliding closed cover 103 moves along the slide block 104 to open the display panel 106 for parameter preset. After use, the closed cover 103 is magnetically positioned with the top plate 102 to protect the display panel 106.

[0054] Insert the connecting wires 107 of multiple weighing sensors into the rear interface of the instrument through the connector 108. The connector 108 is automatically clamped and initially fixed by the clip 214. No additional tools are needed. Release the handle 302 of the clamp 308, and the spring 2 304 will reset and push the clamp 308. The rear groove 303 of the cable tray 301 will collect the excess cable and prevent the cable from scattering and tangling.

[0055] After the equipment is started, the multi-point weighing sensors synchronously collect weight data and transmit it to the force control instrument 100 through the connecting cable 107. The instrument has built-in weight and weightless calibration functions to calibrate the deviation of each sensor. After being processed by a multi-level data equalization algorithm, interference signals are filtered out, and finally the accurate summary data is output on the display panel 106.

[0056] When the sensor needs to be disassembled, press down the handle 205 to move the sleeve 209 down, squeeze the connecting rod 211 to unfold the clamp 214, and pull out the connector 108 directly. When adjusting the cable length, pull the handle 302 to move the clamp 308 to compress the spring 304. After releasing the cable to adjust the length, reset the clamp 308 to clamp and fix it again.

[0057] The device uses multiple sets of load cells distributed at different load-bearing points. The sensors convert the collected weight signals into electrical signals, which are then transmitted to the force control instrument 100 via connecting cable 107. The instrument employs a high-precision data processing module, combined with weight and weightless calibration functions, to calibrate the deviations of each sensor caused by installation location and environmental factors. It then integrates and analyzes multiple sets of data through a built-in equalization algorithm, eliminating outliers and compensating for signal delays, ultimately outputting a stable and accurate comprehensive weight value. This solves the problems of incomplete data collection from a single sensor and large deviations in data from multiple sensors.

[0058] After connector 108 is inserted into the interface, torsion spring 216 applies torsional elastic force to connecting rod 211 through rotating shaft 213, causing lower end sleeve 214 to clamp connector 108. Rubber pad 215 on inner wall of sleeve 214 enhances friction to prevent loosening of connection. The radius of inner wall of pressure sleeve 209 increases from top to bottom. When pressure handle 205 is pressed down, pressure sleeve 209 moves smoothly down along the guide of slide block 208 and slider 207. The ball bearing 212 reduces friction with connecting rod 211, squeezing connecting rod 211 to rotate around rotating shaft 213, causing sleeve 214 to open and unlock. After pressure handle 205 is released, spring 203 returns to its original position through positioning cylinder 201 and positioning rod 204, pushing sleeve 209 up. Torsion spring 216 then causes sleeve 214 to clamp again, realizing quick operation of locking upon insertion and unlocking upon pressing down.

[0059] The rear groove 303 of the cable tray 301 provides storage space for cables. Excess cables can be wound and stored between the cable tray 301 and the rear of the instrument. The side block 307, spring 2 304, and clamping block 308 form a clamping structure. The elastic force of spring 2 304 pushes clamping block 308 to fit tightly against the cable. Positioning cylinder 2 306 and positioning rod 2 305 ensure that spring 2 304 does not shift during extension and retraction, thus achieving stable clamping of the cable and preventing cable pulling and wear caused by equipment movement or vibration, ensuring the stability of data transmission.

[0060] Multi-sensor distributed acquisition covers the entire load-bearing area. The instrument's calibration function and equalization algorithm effectively calibrate the data deviation of each support point, improving data accuracy compared to traditional single-support acquisition. This avoids production errors caused by inaccurate data. The elastic sleeve 214, together with the rubber pad 215, ensures a stable clamping of the connector 108, preventing poor contact caused by driving or vibration. The push-to-unlock design requires no tools, improving disassembly and assembly efficiency compared to traditional bolt fixing and significantly reducing maintenance costs.

[0061] The coordinated design of the cable tray 301 and the clamp 308 keeps the cables neatly organized and prevents them from getting tangled. The elastic clamping of the clamp 308 can accommodate cables of different thicknesses, reducing cable pulling and wear and extending service life. The magnetic design of the closing cover 103 enables quick protection of the display panel 106. The slot of the bracket 101 facilitates the positioning and installation of the equipment. All moving parts are equipped with guide structures to ensure smooth operation without jamming and improve the user experience.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
