[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0018] like Figure 1-6 As shown, this utility model discloses a balance support for improving weighing accuracy, including a fixed base 100, a support arm 600, a feeding bracket 700, a stepper motor 500, a linear slide rail 200, a slide table 300, a slider 400, and a silicone pad 610. The fixed base 100 provides a stable foundation, ensuring that the entire device operates without shaking.

[0019] In one specific embodiment of this utility model, the bottom of the fixed base 100 and the desktop are fixed by screws. The stepper motor 500 and the linear slide rail 200 are both connected to the fixed base 100. A slide table 300 is slidably connected on the linear slide rail 200, and a slider 400 is fixedly connected to the slide table 300. The top of the slider 400 is connected to the support arm 600.

[0020] In one specific embodiment of this utility model, the support arm 600 is made of a high-strength and lightweight material (aerospace aluminum alloy), possessing excellent rigidity and toughness to ensure stable support of the weighing frame. Silicone pads 610 are installed at the four corners of its square support body 630 to support the unloading bracket 700. Utilizing the elastic properties of silicone, the impact force during item placement is buffered, preventing instantaneous overload of the weighing sensor. Simultaneously, it absorbs the vibration energy transmitted by the robotic arm's movement, reducing the impact of vibration on weighing accuracy. The surface of the silicone pads 610 is treated to provide moderate friction, preventing item slippage and further stabilizing the weighing process. One end of the support arm 600 is connected to the slider 400, used to drive the unloading bracket 700 to rise and fall.

[0021] In one specific embodiment of this utility model, the stepper motor 500 is embedded in the C-shaped groove 110 and supported on the connecting support block 120. By receiving commands from the control system, it precisely controls the extension and retraction of the support arm 600. When the robotic arm 900 approaches, the support arm 600 is pre-adjusted to the ideal position to avoid collision. During weighing, the control system provides real-time weighing feedback through the weighing balance 800. After a delay, if the weighing data still fluctuates significantly, it is determined that there is a slight offset of the weighing frame caused by vibration, external force, etc. After the unloading bracket 700 is lifted again, the signal of the stepper motor 500 is adjusted to a smaller number of steps, and the frame is placed again until the weighing data stabilizes, thereby maintaining the reliability of weighing.

[0022] In one specific embodiment of this utility model, the material feeding bracket 700 is made of a high-strength and lightweight material (aerospace aluminum alloy) and is used to place the material box.

[0023] In the specific connection of this utility model balance bracket, firstly, the linear slide rail 200 is placed in the positioning groove 111, the fourth connection hole 210 is aligned with the third connection hole, and then connected with countersunk bolts. Next, the sixth connection hole 310 is aligned with the fifth connection hole 410, and then connected with countersunk bolts. Then, the lower end of the stepper motor 500 is placed on the connecting support block 120, so that the second connection hole 123 is aligned with the ninth connection hole, and the eleventh connection hole 430 is aligned with the tenth connection hole, and then connected with countersunk bolts. Finally, the first connection hole 121 is aligned with the twelfth connection hole on the table and connected with screws. Then, the seventh connection hole 420 is aligned with the eighth connection hole 620 and connected with screws.

[0024] In practical application, the weighing balance 800 is placed below the unloading bracket 700. When the robotic arm 900 carrying the material to be weighed approaches the unloading bracket 700, the stepper motor 500 quickly adjusts the support arm 600 according to a preset program, controlling the support arm 600 and the unloading bracket 700 to be in the optimal receiving position. The robotic arm 900 smoothly places the material to be weighed into the unloading bracket 700. The silicone pad 610 immediately buffers the impact force, and the stepper motor 500 then slowly lowers the unloading bracket 700. As the unloading bracket 700 is smoothly placed on the weighing balance 800, after the weighing data received from the weighing balance 800 stabilizes, an accurate weighing result is finally output for subsequent operations (such as quality judgment and material distribution).

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
