Description

Technical Field

[0001] This utility model relates to the field of assembly line weighing, and in particular to an automatic weighing device for assembly lines. Background Technology

[0002] In modern industrial production lines, product weighing is a crucial step in ensuring product quality and specification consistency. Traditional weighing methods on production lines often rely on manual operation, which is not only inefficient but also prone to weighing errors due to human factors, thus affecting product quality.

[0003] With the continuous development of automation technology, automatic weighing devices are gradually being applied to assembly line production. However, existing automatic weighing devices have a fixed displacement of the pusher plate in the pushing mechanism when dealing with materials of different sizes. This displacement cannot be adjusted, often requiring the replacement of different pushing mechanisms for materials of different volumes, which is cumbersome and costly. Alternatively, using the same pushing mechanism results in increased displacement of the pusher plate when pushing smaller materials, leading to higher energy consumption of the drive components and hindering energy conservation and emission reduction. Therefore, developing an automatic weighing device for assembly lines that can effectively solve the above problems is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to provide an automatic weighing device for production lines, which solves the problem that existing automatic weighing devices have a fixed displacement of the pusher plate of the pushing mechanism when dealing with materials of different sizes. This displacement cannot be adjusted, and different pushing mechanisms are often required to weigh materials of different volumes, which is cumbersome and costly. Alternatively, the same pushing device can be used, which increases the displacement of the pusher plate when pushing small materials, resulting in higher energy consumption of the drive components and hindering energy conservation and emission reduction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic weighing device for an assembly line includes a weighing unit, a conveyor belt in front of the weighing unit, and collection frames on both sides of the weighing unit. The weighing unit includes a weighing platform and a pushing assembly. The pushing assembly is positioned above the weighing platform and includes a first push plate, a second push plate, and a bidirectional lead screw. The first push plate and the second push plate are respectively threaded to both sides of the bidirectional lead screw. The bidirectional lead screw is used to adjust the distance between the first push plate and the second push plate to accommodate weighing materials of different sizes, thereby adaptively adjusting the displacement of the first push plate and the second push plate.

[0006] Preferably, the weighing unit further includes a weight sensor and a material discharge chute. The weight sensor is disposed on the weighing platform, and the material discharge chute is configured in two sets, which are respectively fixedly connected to both sides of the weighing platform.

[0007] Preferably, the collection frame is located below the material discharge chute.

[0008] Preferably, the feeding assembly further includes a movable base, a knob, and a linear motor. The knob is located on one side of the movable base, and the linear motor is connected to the movable base.

[0009] Preferably, the first push plate and the second push plate are slidably connected in the movable seat. The first push plate is used to push materials of the qualified weight into one of the collection boxes, and the second push plate is used to push materials of the unqualified weight into the other collection box.

[0010] Preferably, the knob is fixedly connected to one end of the bidirectional lead screw.

[0011] Preferably, the linear motor is electrically connected to the controller, and the controller is electrically connected to the weight sensor. The controller controls the linear motor to move in the forward and reverse directions according to the signal transmitted by the weight sensor.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This automatic weighing device for production lines can adapt to materials of different sizes by adjusting the distance between the first and second push plates via a bidirectional screw. It does not require changing the pushing mechanism or making complex adjustments, thus improving the versatility and flexibility of the device. Furthermore, the adjustment of the distance between the first and second push plates reduces the amount of displacement of the first and second push plates when pushing small materials, thereby reducing the energy consumption of the drive equipment, meeting the requirements of energy conservation and emission reduction, and reducing production costs.

[0019] 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.

[0020] Example 1: This utility model provides the following... Figures 1-3 An automatic weighing device for an assembly line is shown, comprising a weighing unit 1, a conveyor belt 2 in front of the weighing unit 1, and collection frames 3 on both sides of the weighing unit 1. The weighing unit 1 includes a weighing platform 11 and a pushing assembly 13. The pushing assembly 13 is positioned above the weighing platform 11 and includes a first push plate 132, a second push plate 133, and a bidirectional lead screw 134. The first push plate 132 and the second push plate 133 are respectively threaded to both sides of the bidirectional lead screw 134. The bidirectional lead screw 134 is used to adjust the distance between the first push plate 132 and the second push plate 133 to accommodate weighing materials of different sizes, thereby adaptively adjusting the displacement of the first push plate 132 and the second push plate 133.

[0021] By adjusting the distance between the first push plate 132 and the second push plate 133 using the bidirectional lead screw 134, the device can accommodate weighing materials of different sizes without replacing the pushing mechanism or making complex adjustments. This improves the versatility and flexibility of the device. Furthermore, adjusting the distance between the first push plate 132 and the second push plate 133 reduces the amount of displacement that the first push plate 132 and the second push plate 133 can make for small materials, thereby reducing the energy consumption of the drive equipment, meeting the requirements of energy conservation and emission reduction, and reducing production costs.

[0022] Furthermore, the weighing unit 1 also includes a weight sensor 12 and a material discharge chute 14. The weight sensor 12 is mounted on the weighing platform 11, and the material discharge chute 14 is configured in two sets and is fixedly connected to both sides of the weighing platform 11 respectively.

[0023] Furthermore, the collection box 3 is positioned below the material discharge chute 14.

[0024] Example 2: This utility model provides the following... Figures 1-3An automatic weighing device for an assembly line is shown, comprising a weighing unit 1, a conveyor belt 2 in front of the weighing unit 1, and collection frames 3 on both sides of the weighing unit 1. The weighing unit 1 includes a weighing platform 11 and a pushing assembly 13. The pushing assembly 13 is positioned above the weighing platform 11 and includes a first push plate 132, a second push plate 133, and a bidirectional lead screw 134. The first push plate 132 and the second push plate 133 are respectively threaded to both sides of the bidirectional lead screw 134. The bidirectional lead screw 134 is used to adjust the distance between the first push plate 132 and the second push plate 133 to accommodate weighing materials of different sizes, thereby adaptively adjusting the displacement of the first push plate 132 and the second push plate 133.

[0025] Furthermore, the feeding assembly 13 also includes a movable base 131, a knob 135, and a linear motor 136. The knob 135 is located on one side of the movable base 131, and the linear motor 136 is connected to the movable base 131.

[0026] Furthermore, the first push plate 132 and the second push plate 133 are slidably connected in the movable seat 131. The first push plate 132 is used to push the qualified weight of material into one side of the collection box 3, and the second push plate 133 is used to push the unqualified weight of material into the other side of the collection box 3.

[0027] Furthermore, the knob 135 is fixedly connected to one end of the bidirectional lead screw 134.

[0028] Furthermore, the linear motor 136 is electrically connected to the controller, and the controller is electrically connected to the weight sensor 12. The controller controls the linear motor 136 to move in the forward and reverse directions according to the signal transmitted by the weight sensor 12.

[0029] Working principle: First, based on the size of the material, the double-acting screw 134 is rotated by rotating the knob 135, thereby adjusting the distance between the first push plate 132 and the second push plate 133 so that the two push plates can adapt to the volume of the material and ensure that the material will not fall or get stuck during the pushing process.

[0030] The material to be weighed is conveyed to the center of the weighing platform 11 of the weighing unit 1 via conveyor belt 2, and the material is conveyed in an orderly manner on the conveyor belt. The weight sensor 12 installed on the weighing platform 11 detects the weight of the material and transmits the detected weight signal to the controller. The controller determines whether the material is qualified based on the signal transmitted by the weight sensor 12. If the material is qualified, the controller controls the linear motor 136 to move forward, driving the moving seat 131 and the first push plate 132 to move forward, pushing the qualified material into the discharge chute 14 on one side, and the material slides down the discharge chute 14 into the collection frame 3 below. If the material is unqualified, the controller controls the linear motor 136 to move in the opposite direction, driving the moving seat 131 and the second push plate 133 to move forward, pushing the unqualified material into the discharge chute 14 on the other side, and the material slides down the discharge chute 14 into the collection frame 3 on the other side. After the material is pushed, the linear motor 136 drives the material pushing assembly 13 to reset, ready for the next weighing and material pushing operation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
