Description

Technical Field

[0001] This invention relates to the technical field of weight detection, specifically to a six-station automated weight loading device. Background Technology

[0002] The core principle of weight testing is to rely on a high-precision electronic scale to accurately collect and measure the actual weight of the weight, compare the actual weight value obtained with the nominal weight of the weight, and combine it with a preset accuracy threshold to determine whether the weight meets the legal metrological standards.

[0003] In existing technologies, weight testing typically involves completing all operations at a single workstation, with all processes carried out sequentially at the same workstation, resulting in low testing efficiency. As the testing batch size increases, the serial processing mode at a single workstation leads to a linear increase in testing time, which cannot keep up with the pace of large-scale weight production and metrological calibration, severely restricting overall testing efficiency and failing to meet the demands for efficient and large-scale testing applications. Therefore, a six-workstation automated weight loading device is proposed. Summary of the Invention

In large-scale production and metrological calibration scenarios, as the number of weights to be tested increases, the six-station device can process multiple weights concurrently. Compared to the serial processing mode where the testing time increases linearly at a single station, its testing efficiency is significantly improved, thus solving the problem of low testing efficiency at a single station.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a six-station automated weight loading device, which has the following advantages: 1. This six-station automated weight loading device, with at least six support bases, can simultaneously load multiple weights. In large-scale production and metrological calibration scenarios, as the number of weights to be tested increases, the device can process multiple weights concurrently. Compared to the single-station testing mode, its testing efficiency is significantly improved, effectively meeting the needs of high-efficiency operations.

[0018] 2. This six-station automated weight loading device achieves more flexible and precise weight loading through the coordinated operation of a rotating mechanism, a lifting mechanism, a linear moving mechanism, and a transfer unit. Specifically, the rotating mechanism drives the lifting and linear moving mechanisms to rotate as a whole, thereby adjusting the orientation of the transfer unit; the lifting mechanism drives the transfer unit to move up and down, facilitating the loading and unloading of weights; and the linear moving mechanism enables horizontal displacement of the transfer unit, accurately placing the weights onto the corresponding support seats, effectively improving the accuracy of weight loading.

[0019] 3. This six-station automated weight loading device, through the installation of a marking mechanism, can mark the weights, thereby facilitating weight management and identification. When the lifting mechanism moves the transfer unit downward and presses the first slider, the transmission mechanism drives the second slider to move outward, thereby causing the marking unit to contact the weight and complete the marking.

[0020] 4. This six-station automated weight loading equipment uses air knives that introduce airflow through inlet pipes to clean dust and debris from the worktable. A static pressure sensor monitors the air knife's operating status in real time to ensure effective cleaning. Motor two drives a screw to rotate, causing plate three to slide on the column, thereby adjusting the height of the air knife and enabling cleaning of different locations.

[0023] 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.

[0024] In existing technologies, weight testing typically employs a single workstation to complete all operations, with all processes concentrated in one station and carried out sequentially, resulting in low testing efficiency. As the testing batch size increases, the serial processing mode at a single workstation leads to a linear increase in testing time, failing to keep pace with the large-scale production and metrological calibration of weights. This severely restricts overall testing efficiency and cannot meet the demands for efficient and large-scale testing applications. To address the problem of low detection efficiency, this invention proposes a six-station automated weight loading device.

[0025] As attached Figure 1-5As shown, the loading device includes a chamber 110, a weighing platform 120, a base plate 130, and a workbench 140. The weighing platform 120 is located inside the chamber 110 and is used to measure weights. A base plate 130 is fixed to one side of the chamber 110, and a workbench 140 is fixed to the base plate 130. At least six support seats 150 are provided on the top of the workbench 140 for supporting weights (not shown in the figures). A rotating mechanism 200 is mounted on the top of the base plate 130, a lifting mechanism 300 is mounted on the top of the rotating mechanism 200, and a linear moving mechanism 400 is mounted on the top of the lifting mechanism 300. A transfer part 500 is equipped on the linear moving mechanism 400. The rotation angle of the transfer section 500 can be adjusted by the rotation mechanism 200 so that the transfer section 500 can dock with multiple support seats 150; the height of the transfer section 500 can be changed by the lifting mechanism 300 so as to separate the weights on the support seats 150; finally, the transfer section 500 is moved to the scale body 120 by the linear movement mechanism 400.

[0026] Specifically, the rotating mechanism 200 first drives the lifting mechanism 300, the linear moving mechanism 400, and the transfer part 500 to rotate synchronously, adjusting the orientation of the transfer part 500 to align it with the weight supported by one of the support seats 150 on the worktable 140. Then, the lifting mechanism 300 moves, causing the linear moving mechanism 400 and the transfer part 500 to descend synchronously, ensuring the transfer part 500 smoothly contacts and firmly holds the weight. Next, the lifting mechanism 300 rises, completely separating the weight from the support seat 150. Afterwards, the rotating mechanism 200 further fine-tunes its angle according to the position of the chamber 110, simultaneously cooperating with the linear moving mechanism 400 to drive the transfer part 500 to move horizontally, smoothly transporting the weight to be tested into the chamber 110, aligning it with the detection area of ​​the weighing body 120. Then, the lifting mechanism 300 slowly descends again, causing the transfer part 500 to place the weight on the weighing body 120. After the transfer unit 500 releases the weight, it rises and resets under the drive of the lifting mechanism 300. Simultaneously, the linear moving mechanism 400 moves the transfer unit 500 out of the chamber 110 to avoid interfering with the testing. Finally, the weighing body 120 accurately collects and measures the weight of the weight to be tested based on a preset standard weight testing benchmark. The actual weight value is compared with the nominal weight of the weight, and a preset threshold is used to determine if the weight is qualified. This completes the entire process of transferring and testing a single weight. Subsequently, the transfer unit 500 can be adjusted via the rotating mechanism 200 to connect with the next weight to be tested on the support 150, repeating the above transfer and testing process to achieve batch testing.

[0027] In this embodiment, the rotating mechanism 200 includes a base 210, a first plate 220, a first gear 230, and a second gear 240. The base 210 is fixed to the top of the base plate 130, and the second gear 240 is rotatably connected to the top of the base 210. The first plate 220 is fixed to one side of the base 210, and the first gear 230 is rotatably connected to the first plate 220. A motor (not shown in the figures) is fixed to the bottom of the first plate 220, and the motor output shaft is fixedly connected to the shaft of the first gear 230. The first gear 230 meshes with the second gear 240. When the motor operates, it drives the first gear 230 to rotate, causing the second gear 240 to rotate accordingly through gear meshing. This, in turn, drives the second plate 250 fixed to the top of the second gear 240 to rotate, thereby changing the rotation angle of the transfer part 500 so that it can dock with the support base 150.

[0028] In this embodiment, the lifting mechanism 300 is a hydraulic lifting frame. Using hydraulic oil as the transmission medium, a hydraulic pump converts mechanical energy into hydraulic energy, driving the piston in the hydraulic cylinder to perform linear reciprocating motion, thereby moving the lifting platform of the lifting frame up and down. This is existing technology and will not be described further here. The linear movement mechanism 400 is a lead screw slide. Its principle is based on the meshing transmission between the lead screw and the nut, converting the rotational motion output by the motor into linear motion. The lead screw slide mainly consists of a ball screw, a sliding nut, a guide rail, and a drive motor. When the drive motor drives the ball screw to rotate, the sliding nut meshing with the lead screw will perform a smooth linear reciprocating motion along the lead screw axis, thereby driving the transfer part 500 fixed on the nut to move horizontally synchronously. This is also existing technology and will not be described further here.

[0029] In this embodiment, the transfer unit 500 includes a mounting plate 510, a support plate 520, and a through groove 540. The support plate 520 is fixedly connected to one side of the mounting plate 510, and the through groove 540 is formed on the support plate 520. The support base 150 includes a support plate 151, partitions 152, and baffles 153. The top of the support plate 151 is fixed with regularly arranged partitions 152, and the top of the support plate 151 is also fixed with baffles 153. The weight is placed on the top of the multiple partitions 152. The support plate 520 can be directly inserted into the groove formed between adjacent partitions 152, and then move smoothly under the weight to support the weight. The through groove 540 can prevent the support plate 520 from interfering with the partitions 152, ensuring that the support plate 520 slides smoothly on the partitions 152 and ensuring the stability of the weight transfer process.

[0030] As attached Figure 1-5As shown, a marking mechanism 600 is provided on the top of the workbench 140 near the outer side of the support base 150. The marking mechanism 600 includes a housing 610, a first slider 620, a second slider 630, and a marking part 660. The housing 610 is fixedly mounted on the top of the workbench 140. The first slider 620 is slidably connected to one side of the housing 610 and is equipped with a transmission mechanism inside. The second slider 630 is also slidably connected to the housing 610. The marking part 660 is fixedly mounted on one side of the second slider 630, and pressure plates 550 are fixed on both sides of the bearing plate 520. When the scale body 120 detects that the weight is unqualified, the transfer unit 500 first places the unqualified weight back on top of the multiple partitions 152. Then, the lifting mechanism 300 drives the transfer unit 500 to move downward. At this time, the pressure plate 550 simultaneously presses down on the slider 620, triggering the transmission mechanism inside the box to convert the vertical downward pressure into a horizontal driving force, which drives the slider 630 to move with the marking unit 660 to the side of the unqualified weight. This allows the marking unit 660 to complete the marking operation of the unqualified weight, making it convenient for staff to quickly identify the test results of the weight.

[0031] In this embodiment, the friction between the weight and the fork plate and the weighing platform generates electrostatic attraction. This force is superimposed on the weight's weight, causing the scale reading 120 to be too high. Conventional testing cannot distinguish between "gravity error" and "electrostatic error." Therefore, a scheme to reduce electrostatic discharge is proposed. A spring 640 is fixed to one side of slider 2 630, and a spring piece 650 is fixed to one side of spring 640. The spring piece 650 is connected to a cable, which is connected to the ground. Before testing the weight, the lifting mechanism 300 controls the transfer part 500 to descend a certain height. At this time, the transfer part 500 applies pressure to slider 1 620, and the transmission mechanism drives slider 2 630 to move, causing the spring piece 650 to adhere to both sides of the weight. At this time, the static electricity of the weight to be tested is conducted through the spring piece 650 to the cable and finally to the ground, thereby reducing the impact of static electricity on the testing of the weight.

[0032] Specifically, the spring 650 has a matching through hole at the position corresponding to the marking part 660. The marking part 660 can slide along the through hole to achieve linkage with the spring 650. When the weight is detected to be unqualified, the transfer part 500 puts the unqualified weight back onto the partition 152 of the support base 150. Then, the lifting mechanism 300 drives the transfer part 500 to move downward in segments: when descending the first segment, the transfer part 500 drives the spring 650 to move towards the weight side through the pressure plate 550, so that the spring 650 is tightly attached to both sides of the weight to be tested, thereby limiting and fixing the weight and preventing the weight from shifting during the marking process; after the spring 650 has completed the limiting, the lifting mechanism 300 continues to descend the second segment, and through the linkage of the transmission mechanism, drives the marking part 660 to extend along the through hole of the spring 650 to complete the marking operation of the unqualified weight. The structure of the marking unit 660 can be flexibly selected. It can use a metal marking component or a color signal pen-type marking component. Both forms can adapt to the linkage action of spring limit and marking unit extension and retraction, without affecting the stable realization of the dual functions of limit and marking, and can meet the marking needs of weights in different scenarios.

[0033] More specifically, when the scale body 120 detects that the weight is unqualified, it transmits the data to the controller. After judgment, the controller controls whether the lifting mechanism 300 descends to the second stage, so that the marking mechanism 600 can mark the weight. The core control principle is that after the controller receives the weight detection data of the weight transmitted by the scale body 120, it compares it with the pre-stored nominal weight of the weight and the threshold in real time. Based on the judgment result, it generates the corresponding action control command and sends it to the lifting mechanism 300, realizing the precise triggering and segmented driving of the marking action. Moreover, this process forms a structural linkage with the transfer unit 500 and the support base 150 to ensure the accuracy and automation of the marking operation.

[0034] As attached Figure 1-5The transmission mechanism includes rack 1 810, wedge 820, spring 1 830, gear 3 840, rack 2 850, and spring 2 860. Gear 3 840 is rotatably connected inside the housing 610, and rack 1 810 and rack 2 850 are slidably connected. Rack 2 850 is fixedly connected to slider 1 620, and spring 2 860 is provided between rack 1 810 and housing 610. Spring 1 830 is provided between rack 1 810 and housing 610, and wedge 820 is fixed to one side. Slider 2 630 has two steps on the side near wedge 820. When slider 620 is pressed downwards by transfer part 500, rack 850 slides within housing 610, thereby driving gear 840 to rotate. Since gear 840 meshes with rack 810, rack 810 moves upwards, causing wedge 820 to rise synchronously, thus squeezing slider 630 and moving it towards the weight side. When transfer part 500 stops pressing slider 620, the elasticity of the two springs resets slider 630.

[0035] As attached Figure 1-5 As shown, a cleaning mechanism 700 is provided on the top of the workbench 140. The cleaning mechanism 700 is used to clean the transfer part 500 and detect whether it is deformed. The cleaning mechanism 700 includes a column 710, a plate 720, an air knife 730, an air inlet pipe 740, and a static pressure sensor 750. The top of the workbench 140 is symmetrically provided with columns 710. The plate 720 is slidably connected to the column 710. A motor 760 is fixed to the top of one of the columns 710. A screw is fixed to the output shaft of the motor 760. The screw is rotatably connected to the column 710 and threadedly connected to the plate 720. The operation of the motor 760 can drive the screw to rotate, thereby driving the plate 720 to move up and down between the two columns 710. An air knife 730 is inserted into the plate 720. An air inlet pipe 740 is fixed to one side of the air knife 730 and is connected to an external air source. A static pressure sensor 750 is connected to the air knife 730. The static pressure sensor 750 detects the static pressure inside the air knife 730.

[0036] Specifically, when the lifting mechanism 300 lowers the transfer unit 500 to the first stage, the air knife 730 is precisely positioned at the center of the transfer unit 500. At this time, gas is sent into the air inlet pipe 740 by controlling the air source. After the gas is guided into the air knife 730 through the air inlet pipe, it is transformed into an air curtain by the air knife 730, which then cleans the transfer unit 500. When the data detected by the static pressure sensor 750 is transmitted to the controller, the controller compares the collected data with preset standard data to determine whether the transfer unit 500 has deformed or whether the cleaning operation has been completed. Furthermore, the height of the air knife 730 can be driven by controlling the operation of the motor 760, allowing the air knife 730 to clean the weights.

[0037] More specifically, the static pressure sensor 750 detects the static pressure value of the airflow formed after the air knife curtain blows onto the transfer section 500. This static pressure value fluctuates regularly with changes in the amount of dust adhering to the surface of the transfer section 500 and its own structural morphology. The controller has a pre-stored standard static pressure threshold range matched with the transfer section 500. This range incorporates the basic influence of the structure of the bearing plate 520 through groove 540 on the airflow, providing a benchmark for judgment. The controller dynamically compares the real-time static pressure data collected by the static pressure sensor 750 with the preset standard data to accurately determine the completion status of the cleaning operation and the deformation status of the transfer section. The specific judgment logic is as follows: The principle for determining the completion of the cleaning operation is as follows: During the initial purging, dust and impurities adhere to the surface of the support plate 520 of the transfer unit 500, which will obstruct the air curtain output by the air knife. This will cause the static pressure value formed by the rebound of the airflow after contacting the support plate 520 to be relatively high and fluctuate. As the air curtain continues to purge the support plate 520, the surface dust is gradually removed, the contact surface of the support plate 520 tends to be flat, and the static pressure value formed by the rebound of the airflow will gradually decrease and tend to stabilize. When the real-time static pressure value collected by the controller falls into the preset standard static pressure range for cleaning completion, and the value remains stable for a preset time, it can be determined that the cleaning operation of the transfer unit 500 is completed, and the purging can be stopped or the next process can be started.

[0038] The principle for determining the deformation of the transfer section 500: If the support plate 520 of the transfer section 500 undergoes structural deformation such as bending, warping, or denting, it will change the contact pattern between the air curtain and the transfer section. The airflow will form an abnormal static pressure distribution in the deformation area, causing the real-time static pressure value collected by the static pressure sensor 750 to continuously deviate from the preset standard static pressure threshold range, and it will not stabilize as the purging time increases. Even if there is no dust on the surface of the transfer section 500 and the cleaning operation is completed, if the real-time static pressure value still exceeds the standard threshold range, the controller can determine that the transfer section 500 has undergone structural deformation. At the same time, based on the deviation range and fluctuation pattern of the static pressure value, it can help determine the approximate location of the deformation of the support plate 520, providing a reference for subsequent maintenance.

[0039] In this embodiment, a plate 910 is fixed to the top of the workbench 140. Negative pressure pipes 920 are regularly arranged and fixed on the top of the plate 910 and are connected to a negative pressure system (not shown in the drawings). A through hole 530 is provided on the support plate 520 to cooperate with the negative pressure pipe 920. When the air knife 730 sprays an air curtain for cleaning, impurities can be guided to the outside and collected through the negative pressure pipe 920 by the operation of the negative pressure system.

[0040] The controller in this invention is not shown in the accompanying drawings. This controller is existing technology and is a mature control unit commonly used in industrial control fields, such as a PLC, microcontroller, or MCU. It possesses conventional functions such as signal reception, analog-to-digital conversion, data processing, logic judgment, and control command output. It can process sensor signals and drive and control actuators such as motors. This invention only utilizes the conventional functions of existing controllers, combined with the structural layout and sensor arrangement of this invention, to achieve specific signal linkage and execution control logic. It does not improve the controller's structure, circuitry, or basic program algorithms. Specific models and internal circuit connections can be selected from existing conventional products according to actual control requirements, and will not be elaborated further here.
