They cannot determine in a timely and accurate manner whether the amount of glue used is within tolerance, thus affecting product quality and production efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the problems in related technologies, the purpose of this utility model is to propose a device for inspecting the weight of glue used in electronic products. This device is used to detect whether the amount of glue used in electronic products is within the tolerance range after glue application, so as to accurately detect and ensure product quality and overcome the aforementioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A device for inspecting the weight of glue used in electronic products includes a body, a weighing pan at the top of the body, a high-sensitivity load cell inside the weighing pan, a touch screen and an indicator light on one side of the body, and a processor and a signal amplifier inside the body. The high-sensitivity load cell, the touch screen, the indicator light, and the signal amplifier are electrically connected to the processor via wires.

[0008] The high-sensitivity weighing sensor is used to collect the weight of the electronic products in the weighing pan and convert it into an electrical signal, which is then transmitted to the signal amplifier.

[0009] The signal amplifier is used to amplify the electrical signal output by the high-sensitivity weighing sensor and transmit it to the processor;

[0010] The processor is used to receive the amplified electrical signal and convert it into a weight value, compare the actual measured weight value with the preset upper and lower weight limits, and output a control signal to the indicator light.

[0011] The indicator light is used to display the working status by executing processor control signals;

[0012] The touch display screen is used to input control commands to the processor, including at least setting upper and lower limits for the weight of the processor.

[0013] Furthermore, the device also includes a buzzer, which is electrically connected to the processor, wherein the buzzer is used to execute processor control signals to provide an audible alarm.

[0014] Furthermore, the machine body is also equipped with a power supply for powering the machine.

[0015] Furthermore, the top of the machine body is provided with a groove, and the weighing pan is embedded in the groove.

[0016] Furthermore, a push handle is provided on one side of the machine body to accommodate the touch display screen, and a roller is provided at the bottom of the machine body.

[0017] Furthermore, the high-sensitivity weighing sensor is model HBMU2A weighing sensor.

[0018] Furthermore, the processor is an STM32F103 microcontroller.

[0019] The beneficial effects of this utility model are:

[0020] This invention uses a high-sensitivity weighing sensor and a signal amplifier to accurately collect the weight information of electronic products after glue application. The processor accurately converts the data into a weight value, which is then compared with preset upper and lower weight limits to accurately determine whether the amount of glue applied is within the tolerance range, effectively ensuring product quality. At the same time, the indicator lights and buzzer can intuitively display the working status of the inspection device. When the weight exceeds the range, an audible alarm is issued in a timely manner, making it easy for operators to quickly identify problems and improve production efficiency.

[0021] In addition, the touch screen allows operators to easily input control commands and set parameters such as upper and lower weight limits. The design of the weighing pan embedded in a groove enhances the stability of the device structure, ensures the accuracy of the weighing process, and extends the device's lifespan.

[0029] 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.

[0030] According to an embodiment of the present invention, a device for inspecting the weight of glue used in electronic products is provided.

[0031] like Figures 1-2 As shown, a device for inspecting the weight of glue used in electronic products includes a body 1, a weighing pan 2 at the top of the body 1, a high-sensitivity load cell 12 inside the weighing pan 2, a touch screen display 3 and an indicator light 4 on one side of the body 1, and a processor 5 and a signal amplifier 6 inside the body 1. The high-sensitivity load cell 12, the touch screen display 3, the indicator light 4 and the signal amplifier 6 are electrically connected to the processor 5 through wires.

[0032] The high-sensitivity weighing sensor 12 is used to collect the weight of the electronic products in the weighing pan 2 and convert it into an electrical signal that is transmitted to the signal amplifier 6.

[0033] The signal amplifier 6 is used to amplify the electrical signal output by the high-sensitivity weighing sensor 12 and transmit it to the processor 5;

[0034] Processor 5 is used to receive the amplified electrical signal and convert it into a weight value, compare the actual measured weight value with the preset upper and lower weight limits, and output a control signal to indicator light 4.

[0035] Indicator light 4 is used to display the working status by executing control signals from processor 5;

[0036] The touch display screen 3 is used to input control commands to the processor 5, including at least setting upper and lower limits for the weight to the processor 5.

[0037] The unit 1 also includes a buzzer 7, which is electrically connected to the processor 5. The buzzer 7 is used to execute the control signals from the processor 5 to provide an audible alarm. The unit 1 also contains a power supply 8 for powering the system.

[0038] In this technical solution, when the weight of the electronic product being potted exceeds the preset upper and lower weight limits, the buzzer 7 sounds an alarm to promptly remind the operator. Simultaneously, the power supply 8 provides stable power support for the entire inspection device, ensuring its normal operation without the need for complex external power lines, making it convenient for use in various production environments.

[0039] In addition, the top of the machine body 1 is provided with a groove 9, and the weighing pan 2 is embedded in the groove 9.

[0040] In this technical solution, the embedded weighing pan 2 design makes the weighing pan 2 more stable to install, avoids the weighing pan 2 from shaking during the weighing process, improves the weighing accuracy, and also protects the weighing pan 2 and the internal high-sensitivity weighing sensor 12.

[0041] In addition, a push handle 10 is provided on one side of the body 1 to adapt to the touch screen display 3, and a roller 11 is provided at the bottom of the body 1.

[0042] Specifically, the push handle 10 and roller 11 are designed to facilitate the movement of the device by the operator, allowing for flexible adjustment of the device's position on the production line and improving ease of use.

[0043] Furthermore, in this application, the high-sensitivity load cell 12 is model HBMU2A. This model of sensor features high precision and high sensitivity, enabling it to accurately acquire the weight information of electronic products and ensure the reliability of the detection results.

[0044] Meanwhile, processor 5 is an STM32F103 microcontroller. The STM32F103 microcontroller is stable in performance, fast in processing speed, and can quickly and accurately process, analyze and compare received signals, and control the operation of components such as indicator lights and buzzers in a timely manner.

[0045] In addition, signal amplifier 6 can be an AD620 instrumentation amplifier. The AD620 features high precision, low noise, low offset voltage, and high common-mode rejection ratio, which can effectively amplify sensor signals while suppressing noise and interference, ensuring that the amplified signal is accurate and reliable.

[0046] Using the above technical solution, when using this inspection device, the operator first inputs control commands to the processor 5 via the touch screen 3, setting the upper and lower limits of the weight. Then, the glued electronic product is placed on the weighing pan 2, and the high-sensitivity weighing sensor 12 inside the weighing pan 2 collects the weight of the electronic product and converts it into an electrical signal, which is then transmitted to the signal amplifier 6.

[0047] Signal amplifier 6 amplifies the electrical signal and transmits it to processor 5. Processor 5 converts the amplified electrical signal into a weight value and compares it with preset upper and lower weight limits. If the actual measured weight value is within the preset range, processor 5 controls indicator light 4 to display a normal working state (green light illuminates); if the actual measured weight value exceeds the preset range, processor 5 controls indicator light 4 to display an abnormal working state (red light illuminates), and simultaneously controls buzzer 7 to sound an alarm. Throughout the entire operation, power supply 8 provides stable power to the device.

[0048] In summary, the following effects can be achieved by utilizing the above-described technical solution of this utility model:

[0049] This invention uses a high-sensitivity weighing sensor and a signal amplifier to accurately collect the weight information of electronic products after glue application. The processor accurately converts the data into a weight value, which is then compared with preset upper and lower weight limits to accurately determine whether the amount of glue applied is within the tolerance range, effectively ensuring product quality. At the same time, the indicator lights and buzzer can intuitively display the working status of the inspection device. When the weight exceeds the range, an audible alarm is issued in a timely manner, making it easy for operators to quickly identify problems and improve production efficiency.

[0050] In addition, the touch screen allows operators to easily input control commands and set parameters such as upper and lower weight limits. The design of the weighing pan embedded in a groove enhances the stability of the device structure, ensures the accuracy of the weighing process, and extends the device's lifespan.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
