Abstract
Description
Technical Field
[0001] This application relates to the field of silver ingot weighing technology, and more particularly to a silver ingot weighing buffer device. Background Technology
[0002] In the production and processing of silver ingots, weighing is a crucial step. As a precious metal, silver requires extremely high weighing accuracy, typically relying on high-precision load cells. However, existing weighing technologies have significant drawbacks in practical applications: silver ingots are relatively heavy, and collisions and vibrations are inevitable during placement. These dynamic impacts directly affect the load cells, causing momentary overloads and lateral torsional forces. Long-term, repeated impacts not only reduce the measurement accuracy of the sensors but also easily lead to fatigue or even damage to the sensor's mechanical structure. Furthermore, high-precision sensors are expensive, and frequent replacements further increase production costs.
[0003] Current solutions attempt to mitigate impact by manually placing the ingots slowly or adding cushioning pads, but these methods are inefficient and have limited cushioning effect, making it difficult to completely eliminate the negative impact of dynamic loads on the sensor. The impact problem is particularly pronounced in automated production lines when robotic arms rapidly place silver ingots.
[0004] Therefore, there is an urgent need for a weighing buffer device that can effectively isolate vibration and eliminate impact, so as to extend the service life of the sensor and reduce maintenance costs while ensuring weighing accuracy. Utility Model Content
[0005] To solve or partially solve the problems existing in the related technologies, this application provides a silver ingot weighing buffer device, which aims to solve the problem that the impact load directly acts on the sensor when the silver ingot is placed on the weighing device.
[0006] This application provides a silver ingot weighing buffer device, comprising:
[0007] Lifting platform, connecting rod, load-bearing platform, electric push rod, and weighing instrument;
[0008] The electric push rods are installed on both sides of the weighing instrument, and the initial height of the electric push rods is higher than the height of the weighing instrument.
[0009] The lifting platform is mounted on an electric push rod. A window is opened in the middle of the lifting platform, which is located directly above the weighing instrument. The connecting rod is installed on the inner sides of the four sides of the window in the middle of the lifting platform.
[0010] The load-bearing platform is mounted on the connecting rod and can slide on the connecting rod. The height of the load-bearing platform is greater than the thickness of the lifting platform. When the electric push rod drives the lifting platform to descend, the load-bearing platform contacts the weighing instrument first.
[0011] Optionally, in some embodiments, the support platform includes:
[0012] The outer cover, slide rails, and windows; the outer cover is a square box, with the top of the outer cover used to hold silver ingots.
[0013] The slide is a U-shaped groove, which is located in the middle of the four vertical sides of the outer cover. The width of the slide is greater than the diameter of the connecting rod. The outer cover is installed on the connecting rod through the slide.
[0014] The outer cover has windows on all four vertical sides to reduce its weight.
[0015] Optionally, in some embodiments, the silver ingot weighing buffer device further includes:
[0016] Proximity switches; proximity switches are installed on the lifting platforms on both sides of the support platform to detect whether the silver ingot has been placed on the support platform.
[0017] The technical solution provided in this application may include the following beneficial effects:
[0018] The electric push rod, lifting platform, and connecting rod support the load-bearing platform. The load-bearing platform absorbs the vibration and impact force when the silver ingot is placed. The electric push rod then slowly lowers the silver ingot and the load-bearing platform onto the weighing instrument, and the lifting platform, connecting rod, and load-bearing platform are separated to complete the weighing. This effectively isolates the vibration and impact force when the silver ingot is placed, and solves the problem of the impact load acting directly on the sensor.

[0029] In the production and processing of silver ingots, weighing is a crucial step. As a precious metal, silver requires extremely high weighing accuracy, typically relying on high-precision load cells. However, existing weighing technologies have significant drawbacks in practical applications: silver ingots are relatively heavy, and collisions and vibrations are inevitable during placement. These dynamic impacts directly affect the load cells, causing momentary overload and lateral torsional forces. Long-term, repeated impacts not only reduce the measurement accuracy of the sensors but also easily cause fatigue or even damage to the sensor's mechanical structure. High-precision sensors are expensive, and frequent replacements further increase production costs. Current solutions attempt to mitigate impacts through slow, manual placement or the addition of buffer pads, but these methods are inefficient and have limited buffering effects, failing to completely eliminate the negative impact of dynamic loads on the sensors. The impact problem is particularly pronounced in automated production lines where robotic arms rapidly place silver ingots.
[0030] To address the aforementioned issues, this application provides a silver ingot weighing buffer device. This device uses an electric push rod, a lifting platform, and a connecting rod to support a load-bearing platform. The load-bearing platform absorbs the vibration and impact forces during the placement of the silver ingot. The electric push rod then slowly lowers the silver ingot and the load-bearing platform onto the weighing instrument, allowing the lifting platform, connecting rod, and load-bearing platform to separate during weighing. This effectively isolates the vibration and impact forces during the placement of the silver ingot, solving the problem of impact loads directly acting on the sensor.
[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0032] Figure 1 This is a schematic diagram of the structure of the silver ingot weighing buffer device shown in the embodiments of this application.
[0033] See Figure 1 A silver ingot weighing buffer device, comprising:
[0034] Lifting platform 1, connecting rod 2, load-bearing platform 3, outer cover 301, slide rail 302, window 303, proximity switch 4, electric push rod 5, and weighing instrument 6;
[0035] Two electric push rods 5 are installed on each side of the weighing instrument 6, and the lifting platform 1 is mounted on the telescopic rods of the four electric push rods 5. The initial height of the electric push rods 5 is higher than the height of the weighing instrument 6, ensuring that the lifting platform 1 will not touch the weighing instrument 6 when the electric push rods 5 are retracted to their lowest point, thus ensuring measurement accuracy.
[0036] A square window is provided in the middle of the lifting platform 1, located directly above the weighing instrument 6. The connecting rod 2 is bolted to the inner sides of the window in the middle of the lifting platform 1, facing inwards. The load-bearing platform 3 is mounted on the connecting rod 2. The load-bearing platform 3 includes an outer cover 301, a sliding groove 302, and windows 303. The outer cover 301 is a square box, with the top used to hold silver ingots. The sliding groove 302 is a U-shaped groove located in the middle of the four vertical sides of the outer cover 301, opening downwards in a U-shape. The width of the sliding groove 302 is greater than the diameter of the connecting rod 2. The outer cover 301 is hung on the connecting rod 2 via the sliding groove 302, thus suspending the outer cover 301 directly above the weighing instrument 6. Windows 303 are provided on the four vertical sides of the outer cover 301 to reduce its weight. During use, the weighing platform 3 descends with the electric push rod 5 and the lifting platform 1. The weighing platform 3 first contacts the weighing instrument 6. The lifting platform 1 and the connecting rod 2 continue to descend with the electric push rod 5, so that the connecting rod 2 is no longer in contact with the weighing platform 3, which will not affect the weighing result. After the weighing is completed, the lifting platform 1 and the connecting rod 2 rise with the electric push rod 5, and then the weighing platform 3 is lifted by the connecting rod 2.
[0037] Proximity switches 4 are installed on the lifting platforms 1 on both sides of the support platform 3 to detect whether the silver ingot has been placed on the support platform 3.
[0038] In this application, the initial state of the silver ingot weighing buffer device is that the electric push rod 5, the lifting platform 1, and the connecting rod 2 lift the load-bearing platform 3 into the air. The silver ingot to be measured is placed on the load-bearing platform 3 by a robotic arm, so that the vibration during placement is transmitted to the electric push rod 5 without contacting the weighing instrument 6. After the proximity switch 4 detects that the silver ingot has been placed completely, the controller starts the electric push rod 5 to descend. The load-bearing platform 3 descends along with the electric push rod 5 and the lifting platform 1. The load-bearing platform 3 first contacts the weighing instrument 6, and the lifting platform 1 and the connecting rod 2 continue to descend with the electric push rod 5, causing the connecting rod 2 to disengage from the load-bearing platform 3. After weighing for a certain period of time, the lifting platform 1 and the connecting rod 2 rise with the electric push rod 5, and then the connecting rod 2 lifts the load-bearing platform 3, causing the load-bearing platform 3 to disengage from the weighing instrument 6, completing the reset, and then the robotic arm is controlled to remove the silver ingot.
[0039] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
