[0026] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] An automatic weighing and sorting device includes:

[0029] The base plate 1 has a weighing platform 2 at its upper end, and a first robotic arm 3 and a second robotic arm 7 for moving the workpiece are respectively provided at the upper end of the base plate 1. A support column 9 is fixedly connected to the upper end of the base plate 1, and a sorting component 8 for sorting the workpiece is provided at the upper end of the support column 9.

[0030] A moving component 10 for moving the sorting component 8 is provided above the base plate 1;

[0031] The upper end of the base plate 1 is provided with a storage component 11 for storing the sorting component 8.

[0032] For example, the base plate 1 is made of high-strength, high-stability metal material to ensure that it can withstand the weight of each component and the force generated during workpiece operation throughout the entire equipment operation, remaining stable and not shaking. The weighing platform 2 is equipped with high-precision weighing sensors, which can accurately sense the weight of the workpiece placed on it and transmit the weight data to the equipment's control system in real time, providing an accurate basis for subsequent sorting operations. The first robotic arm 3 and the second robotic arm 7 both have multi-degree-of-freedom motion capabilities, enabling them to flexibly grasp, transport, and place workpieces, meeting the movement needs of different workpieces in different positions. Both the first robotic arm 3 and the second robotic arm 7 use pneumatic suction to pick up workpieces. The first robotic arm 3 and the second robotic arm 7 adopt an articulated robotic arm structure, and their performance parameters can be referenced from similar products from manufacturers such as Siasun Robot & Automation and Estun Automation. The support column 9 stands vertically on the base plate 1, providing stable support for the sorting component 8 above, ensuring that the sorting component 8 remains horizontal and fixed in position during operation.

[0033] The sorting component 8 includes a sorting plate 81, a storage hole 82, and a support rod 83;

[0034] Among them, the upper end of the support column 9 contacts the sorting plate 81, the upper end of the sorting plate 81 is provided with a plurality of symmetrically distributed storage holes 82, and the lower end of the sorting plate 81 is fixedly connected with a plurality of symmetrically distributed support rods 83.

[0035] For example, the sorting plate 81 is made of high-strength, lightweight material to ensure that it can bear the weight of the workpiece while minimizing its own weight, so as to facilitate the movement operation of the moving component 10. The shape and size of these storage holes 82 are carefully designed according to the shape and size of different workpieces, so as to accurately accommodate and fix the workpieces and ensure that the workpieces are stable in position during the sorting process. The support rod 83 plays the role of supporting the sorting plate 81, and at the same time cooperates with the relevant structure in the storage component 11 to achieve stable placement and storage of the sorting plate 81.

[0036] The moving component 10 includes a guide rail 101, an electric slider 102, a first electric push rod 103, and a clamping plate 104;

[0037] The base plate 1 has two evenly distributed guide rails 101 on its upper part. Electric sliders 102 are slidably connected to the outer sides of the two guide rails 101. The upper end of the electric sliders 102 is fixedly connected to a first electric push rod 103. The output end of the first electric push rod 103 is fixedly connected to a clamping plate 104. The clamping plate 104 is in contact with the sorting plate 81. The clamping plate 104 is L-shaped and has a rubber plate inside.

[0038] For example, the two guide rails 101 are made of wear-resistant, high-strength materials and have finely processed surfaces to ensure that the electric slider 102 can slide smoothly on them. The electric slider 102 has a built-in high-performance drive motor and transmission mechanism, which can precisely control its sliding position and speed on the guide rails 101 according to a preset program. The first electric push rod 103 has a telescopic function, which can perform precise displacement control in the vertical direction. The clamping plate 104 contacts the sorting plate 81 and is used to clamp and fix the sorting plate 81 so as to drive it to move. The clamping plate 104 is designed in an L-shape, which can better fit the edge of the sorting plate 81 and provide a more stable clamping force. At the same time, a rubber plate is provided inside the clamping plate 104. The rubber plate has good elasticity and friction, which can play a buffering role during the clamping process to avoid damage to the sorting plate 81 and increase the stability of the clamping.

[0039] Storage component 11 includes storage box 111, second electric push rod 112, lifting plate 113 and through hole 114;

[0040] The upper end of the base plate 1 is fixedly connected to two symmetrically distributed storage boxes 111. The two storage boxes 111 are fixedly connected to two guide rails 101 respectively. The upper end of the base plate 1 is fixedly connected to two symmetrically distributed second electric push rods 112. The output ends of the two second electric push rods 112 are fixedly connected to lifting plates 113. The lifting plates 113 are slidably connected to the storage boxes 111. The interior of the lifting plates 113 has multiple through holes 114 arranged in a ring. The multiple through holes 114 and the storage holes 82 are adapted to the support rods 83.

[0041] For example, the storage box 111 is made of sturdy metal material and has good protective performance, which can protect the sorting component 8 stored inside from damage by the external environment. The two storage boxes 111 are fixedly connected to the two guide rails 101 respectively. This connection method ensures the positional stability of the storage box 111 and also facilitates the moving component 10 to accurately move the sorting component 8 above the storage box 111. The second electric push rod 112 has strong thrust and precise control capability, and can control the lifting height of the lifting plate 113 according to the preset program. Driven by the second electric push rod 112, the lifting plate 113 moves up and down inside the storage box 111. Multiple through holes 114 and storage holes 82 are adapted to the support rod 83. When it is necessary to store the sorting component 8, the moving component 10 moves the sorting component 8 above the storage box 111, and then the second electric push rod 112 pushes the lifting plate 113 up, so that the support rod 83 is inserted into the through hole 114, thereby realizing the stable storage of the sorting component 8.

[0042] A temporary storage platform 4 is fixedly connected to the upper end of the base plate 1, and a first placement plate 5 and a second placement plate 6 are fixedly connected to the upper end of the temporary storage platform 4.

[0043] For example, the temporary storage platform 4 is made of a flat and sturdy material with a non-slip surface to ensure that the workpiece placed on it will not slide or fall. The first placement plate 5 and the second placement plate 6 are divided according to different workpiece types or production processes to store workpieces in different states or categories. For example, the first placement plate 5 can be used for heavier workpieces, while the second placement plate 6 is used to store lighter workpieces.

[0044] Working principle: The external robotic arm smoothly moves the workpiece to the weighing platform 2 and slowly lowers it so that the workpiece is completely placed on the weighing platform 2, ensuring full contact between the workpiece and the weighing platform 2 for accurate weighing. After the high-precision weighing sensor on the weighing platform 2 senses the weight of the workpiece, it transmits the weight data to the control system of the equipment in real time. The control system receives and records the weight data. After weighing is completed, the robotic arm moves to the weighing platform 2 again, grabs the weighed workpiece, and places it on the temporary storage platform 4. Heavier workpieces are placed on the first placement plate 5, and lighter workpieces are placed on the second placement plate 6.

[0045] The second robotic arm 7 places the workpieces from different placement plates onto the upper end of the sorting plate 81. After a batch of workpieces is sorted, the control system directs the moving component 10 to move the sorted sorting plate 81 above the storage box 111. The electric slider 102 slides on the guide rail 101, driving the clamping plate 104 and the sorting plate 81 to accurately move to the designated position directly above the storage box 111. The control system then controls the second electric push rod 112 to extend, pushing the lifting plate 113 upward within the storage box 111. As the lifting plate 113 rises, the sorting plate 81... The lower support rod 83 is gradually inserted into the corresponding through hole 114 on the lifting plate 113. When the support rod 83 is fully inserted into the through hole 114, the sorting plate 81 is stably placed on the lifting plate 113, realizing the storage of the sorting plate 81. At this time, the first electric push rod 103 retracts, driving the clamping plate 104 to release the sorting plate 81. Then the electric slider 102 moves to the initial position, the middle position of the guide rail 101. Another external robotic arm places the empty sorting plate 81 on the upper end of the support column 9. The first electric push rod 103 drives the clamping plate 104 to fix the sorting plate 81.

[0046] The weighing platform 2, the first robotic arm 3, the second robotic arm 7, the electric slider 102, the first electric push rod 103, and the second electric push rod 112 in this application are controlled automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
