Description

Technical Field

[0001] This utility model belongs to the technical field of weighing equipment, specifically relating to a multi-purpose weighing and sorting machine. Background Technology

[0002] Existing weighing equipment typically involves manual placement of the item on the weighing platform. After the weighing sensor collects and displays the weight, the operator manually moves the item to the corresponding weight zone. This traditional method reveals significant limitations in scenarios requiring high efficiency and precision sorting, such as grading seafood, pricing high-value foods by weight, and quality screening and authenticity verification of electronic components. Firstly, the introduction of manual operation not only reduces overall sorting efficiency, making it difficult to meet the demands of large-scale assembly line operations, but also introduces errors during handling, judgment, and placement due to the uncertainty of human factors, affecting sorting accuracy and even causing secondary physical damage to delicate electronic components. Therefore, this invention proposes a multi-purpose weighing and sorting machine to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide a multi-purpose weighing and sorting machine that can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows: This utility model provides a multi-purpose weighing and sorting machine, including a housing and a flipping actuator mounted on the housing. A support platform mechanism is provided on the top surface of the housing. A battery, a weighing module, and a control circuit board are provided inside the housing. The weighing module is electrically connected to the flipping actuator. An adjustment button and a data display screen electrically connected to the control circuit board are provided on the surface of the housing. The flipping actuator includes a first flipping component, a second flipping component, and a weighing pan. The first flipping component and the second flipping component are vertically arranged, and the weighing pan is mounted on the second flipping component. The first flipping component includes a first flipping device, a first flipping stabilizing frame, and a first fixing frame. The rotating shaft on the first flipping device is detachably mounted on the two side plates of the first flipping stabilizing frame and located inside the first flipping stabilizing frame. The first fixing frame is detachably mounted on the upper side of the first flipping device. The first flipping stabilizing frame is detachably mounted on the support shaft on the weighing module, and the first flipping stabilizing frame is set with a gap from the surface of the housing.

[0005] Preferably, the second flipping component includes a second flipping device, a second flipping stabilizing frame, and a second fixing frame. The second flipping device is vertically disposed above the first flipping device. The rotating shaft on the second flipping device is detachably mounted on the two side plates of the second flipping stabilizing frame and located inside the second flipping stabilizing frame. The second flipping stabilizing frame is detachably mounted on the first fixing frame and is perpendicular to it.

[0006] Preferably, the weighing pan is detachably mounted on the flat support plate, and the flat support plate is fixed to the surface of the second fixed frame. The center of the weighing pan is vertically aligned with the center of the second flipping device and the center of the first flipping device. Both the first and second flipping devices are electrically connected to data lines, which pass through the housing and are electrically connected to the control circuit board inside.

[0007] Preferably, the support platform mechanism includes a telescopic sleeve and an inner telescopic cylinder. The inner telescopic cylinder is slidably fitted inside the telescopic sleeve, and an elastic locking member is provided on the inner telescopic cylinder.

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-6 As shown, a multi-purpose weighing and sorting machine includes a housing 1 and a tilting actuator 2 mounted on the housing 1. A support platform mechanism 3 is mounted on the top surface of the housing 1. A battery 4, a weighing module 5, and a control circuit board 6 are mounted inside the housing 1. The weighing module 5 is electrically connected to the tilting actuator 2. An adjustment button and a data display screen, which are electrically connected to the control circuit board 6, are mounted on the surface of the housing 1. The weighing module 5 uses the HX711AD module from AVIA Technology. The flipping actuator 2 includes a first flipping component, a second flipping component, and a weighing pan 28. The first flipping component and the second flipping component are vertically arranged, and the weighing pan 28 is mounted on the second flipping component. The first flipping component includes a first flipping device 21, a first flipping stabilizing frame 22, and a first fixing frame 23. The rotating shaft on the first flipping device 21 is detachably mounted on both side plates of the first flipping stabilizing frame 22 and located inside the first flipping stabilizing frame 22. The first fixing frame 23 is detachably mounted on the upper side of the first flipping device 21. The first flipping stabilizing frame 22 is detachably mounted on the support shaft of the weighing module 5, and the first flipping stabilizing frame 22 is set with a gap from the surface of the housing 1.

[0018] As an optional implementation, refer to the appendix. Figure 3 The second flipping component includes a second flipping device 24, a second flipping stabilizing frame 25, and a second fixing frame 26. The second flipping device 24 is vertically arranged above the first flipping device 21. The rotating shaft on the second flipping device 24 is detachably mounted on the two side plates of the second flipping stabilizing frame 25 and located inside the second flipping stabilizing frame 25. The second flipping stabilizing frame 25 is detachably mounted on the first fixing frame 23 and is vertically arranged therewith. In this way, the four angles of the first flipping device 21 and the second flipping device 24, which are vertically corresponding, can be flipped and adjusted at four angles on the weighing pan 28, which is convenient for sorting four different standard weights.

[0019] Furthermore, the weighing pan 28 is detachably mounted on the flat support plate 27, and the flat support plate 27 is fixed to the surface of the second fixed frame 26. The center of the weighing pan 28 is vertically aligned with the center of the second flipping device 24 and the center of the first flipping device 21. Both the first flipping device 21 and the second flipping device 24 are electrically connected to data lines 29, which pass through the housing 1 and are electrically connected to the control circuit board 6 inside, so that the control circuit board 6 can electrically control the first flipping device 21 and the second flipping device 24. Both the first flipping device 21 and the second flipping device 24 are servo motors.

[0020] See attached document Figure 4 The support platform mechanism 3 includes a telescopic sleeve 31 and an inner telescopic cylinder 33. The inner telescopic cylinder 33 is slidably sleeved inside the telescopic sleeve 31, and an elastic locking member 35 is provided on the inner telescopic cylinder 33. The elastic locking member 35 matches a plurality of vertically arranged locking holes 31a opened on the telescopic sleeve 31. The elastic locking member 35 adopts a spring pin in the prior art. The telescopic sleeve 31 and the inner telescopic cylinder 33 are square cross-section structures that slide and fit together, thereby improving the support stability and anti-rotation effect.

[0021] Furthermore, the lower end of the telescopic sleeve 31 is fixed on the chassis 32, and the upper end of the inner telescopic sleeve 33 is fixed with a support plate 34. The support plate 34 is detachably connected to the extension plates on both sides of the housing 1. This allows the support plate 34 to be easily installed and supported on the housing 1, thereby providing high support for the tilting actuator 2 on the housing 1 for use in different locations.

[0022] See attached document Figure 1 and attached Figure 2 The side of the housing 1 is equipped with a charging port 7 that is electrically connected to the control circuit board 6, which facilitates the charging of the battery 4 and improves the convenience of carrying and using the device when going out.

[0023] See attached document Figure 5 The control circuit board 6 is equipped with a multi-standard weighing control system, which includes an S1 system initialization module, an S2 main control loop module, an S3 weight judgment logic module, and an S4 control execution module. The S1 system initialization module includes: 1. Center the servo motor (horizontal position); 2. Weighing sensor calibration; 3. Load the preset standard weight parameters.

[0024] The S2 main control loop module includes: Weighing data acquisition – 1. Read current weight, 2. Data filtering, 3. Weighing data summary; Parameter setting modes: 1. Standard weight adjustment, 2. Threshold range setting, 3. Angle parameter setting; System status monitoring – 1. Fault detection, 2. Log recording.

[0025] The S3 weight determination logic module includes: 1. Compare the current weight with four standard values; 2. Determine if it falls within the prefabrication range; 3. Determine the direction of the best match.

[0026] The S4 control execution module includes: 1. Calculate the target angle; 2. Smooth motion control; 3. Maintain control over the tilt time; 4. Return to the horizontal position.

[0027] Based on a programmable control system, users can easily set up to four weight standards and their corresponding thresholds via adjustment buttons. The equipment can automatically classify items into multiple grades according to preset parameters, realizing a flexible sorting function of "one machine for multiple uses". This overcomes the shortcomings of traditional equipment that has a single function and relies on manual memory judgment, significantly enhancing the equipment's adaptability to different sorting needs and meeting the requirements of multi-standard and flexible sorting.

[0028] Using the above structure, refer to the appendix. Figure 6 The weighing process is as follows: After the system is powered on, the initialization module is executed first to control the first flipping device 21 and the second flipping device 24 to return to the horizontal position, complete the calibration of the weighing sensor and load the four preset weight standard parameters; then enter the main control loop. In the weighing judgment mode, the weighing module 5 collects the weight data of the items on the weighing pan 28 in real time. After analog-to-digital conversion by the HX711AD module, the data is transmitted to the control circuit board 6. The weight judgment logic module compares the current weight with the four preset standard values ​​and threshold ranges. If the weight falls within a certain standard range, the system determines the grade of the item and triggers the control execution module to calculate the target angle in the corresponding direction. Through the smooth motion control algorithm, the first flipping device 21 and the second flipping device 24 are driven to work together to make the weighing pan 28 tilt smoothly in the predetermined direction, slide the item into the corresponding sorting area, and automatically reset to the horizontal state after maintaining the tilt for a set time, waiting for the next weighing. If the operator intervenes via the adjustment button, the system switches to parameter setting mode, allowing the user to adjust the weight threshold or servo angle parameters of each level in real time. The new parameters will be saved immediately and applied to the subsequent sorting process. Throughout the cycle, the system status monitoring module continuously performs fault detection and operation log recording, and provides real-time feedback on weight data, sorting results and equipment status through the data display screen, forming a complete intelligent weighing and sorting closed-loop control.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
