Description

Technical Field

[0001] The invention belongs to the technical field of product weighing, and in particular relates to a weighing device for weighing a product. Background Art

[0002] The products produced in a certain workshop are cylindrical in shape. After a batch of products are produced, the process requires that the density of each product be measured. After the measurement, the products whose density does not meet the standard requirements are selected out.

[0003] The density measuring device used in the workshop includes a workbench, a weighing scale fixed on the workbench surface, a volume measuring device, a robot arm, and a shelf. The workbench is fixed with a shell covering the weighing scale, the volume measuring device and the shelf, and a window door is opened on the shell.

[0004] The working principle of the density measuring device is: the worker places the product on the shelf, the robot arm clamps the product on the shelf, and then the worker places the product on the weighing scale to weigh the weight of the product; then the volume of the product is measured by a subsequent volume measuring device, and the density of the product is calculated using the density calculation formula.

[0005] However, although the weighing balance used can weigh the weight of the product, it still has the following technical defects:

[0006] I. The weighing balance is always exposed to the outside. When the airflow acts on the surface of the weighing balance, it causes inaccurate weighing of the weighing balance, resulting in inaccurate weight of the weighed product, and there is a technical defect of low weighing accuracy.

[0007] II. When the robot arm places the product on the surface of the weighing scale, the product impacts the weighing scale, causing damage to the weighing scale, which in turn affects the weighing accuracy of subsequent products, and there is a technical defect of low weighing precision.

[0008] Therefore, there is an urgent need for a weighing device that can improve the weighing accuracy of a weighing balance and the weighing precision of a product. Summary of the invention

[0009] The technical problem solved by the present invention is to provide a weighing device for weighing a product, which can improve the weighing accuracy of a weighing balance and improve the weighing precision of the product.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] like Figure 1 to Figure 7 As shown, a weighing device for weighing a product provided by the present invention comprises a pad 1 fixedly mounted on a workbench and a weighing balance mounting assembly 2, wherein the weighing balance mounting assembly 2 comprises a bottom plate 3 and a top plate 4 arranged just above the bottom plate 3, wherein the bottom plate 3 and the top plate 4 are arranged parallel to each other, wherein a plurality of shock-absorbing pads are fixedly mounted between the top plate 4 and the bottom plate 3, wherein a weighing balance 5 is fixedly mounted on the upper surface of the top plate 4, wherein a protective cover 6 is fixedly mounted on the outside of the weighing balance 5, wherein the protective cover 6 is made of a transparent material, and wherein a support rod 7 is fixedly mounted on the upper surface of the weighing balance 5 and passes upward through the outside of the protective cover 6;

[0037] A vertical cylinder 8 is fixedly provided on the upper surface of the pad 1, and a connecting plate 9 is fixedly provided on the active end of the piston rod of the vertical cylinder 8. A transverse plate 10 is fixedly provided on the upper surface of the connecting plate 9. The left end of the transverse plate 10 extends to just above the support rod 7, and a receiving tube 11 for receiving the product is fixedly provided in the left end. The receiving tube 11 is a hollow cylindrical structure, and a plurality of support platforms 12 are fixedly provided on the inner wall of the receiving tube 11 along its circumferential direction. The support platforms 12 are evenly distributed on the inner wall of the receiving tube 11.

[0038] A through hole is provided on the top surface of the shield 6, and the support rod 7 is upwardly penetrated through the through hole. The head of the support rod 7 is a circular structure and has a plurality of notches, the number and position of which match the support platform 12, ensuring that when the accommodating cylinder 11 moves downward, the head of the support rod 7 can pass through the support platform 12 without interference.

[0039] A vertically arranged guide column 13 is fixedly disposed on the upper surface of the pad 1 , a guide hole is opened on the right end of the transverse plate 10 , and the right end of the transverse plate 10 is sleeved on the guide column 13 through the guide hole.

[0040] The working process of the present invention is as follows:

[0041] S1. Place the product 14 to be weighed into the receiving tube 11. Figure 8 As shown, at this time, the plane formed by each support platform 12 supports the product 14;

[0042] S2. Control the piston rod of the vertical cylinder 8 to retract downward, the piston rod drives the connecting plate 9 to move downward, the connecting plate 9 drives the horizontal plate 10 to move downward along the guide column 13, the horizontal plate 10 drives the accommodating cylinder 11 to move downward, the accommodating cylinder 11 drives the product 14 to move downward synchronously, the product 14 moves toward the support rod 7, as the product 14 continues to move downward, the support rod 7 supports the product 14, as shown in FIG. Fig. 9 As shown, the product 14 is separated from each support platform 12, and at this time, the weighing scale 5 weighs the weight of the product 14;

[0043] S3. After weighing, the piston rod of the vertical cylinder 8 is controlled to extend upward, the piston rod drives the connecting plate 9 to move upward, the connecting plate 9 drives the horizontal plate 10 to move upward, the horizontal plate 10 drives the accommodating tube 11 to move upward, and when the support platform 12 in the accommodating tube 11 supports the product 14, the product 14 is separated from the support rod 7.

[0044] Among them, it can be seen from step S2 that the weighing device only needs to put the product 14 into the containing cylinder 11, and then control the piston rod of the vertical cylinder 8 to retract downward, so that the support rod 7 can stably support the product, and then weigh the weight of the product 14. It can be seen that the weighing device effectively avoids the weighing scale 5 from being damaged when the robot arm directly places the product 14 on the surface of the weighing scale 5, thereby effectively improving the accuracy of subsequent product weighing, and then improving the precision of product weighing.

[0045] In addition, the protective cover 6 plays a role in protecting the weighing scale 5, preventing external airflow from acting on the weighing scale 5 and affecting its weighing accuracy, thereby improving the accuracy of product weighing.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
