Description

Technical Field

[0001] This invention relates to the field of production line tooling processing technology, specifically to an automatic weighing and steering device. Background Technology

[0002] As businesses develop, they are increasingly emphasizing product conformity testing and defective product screening in production. Among these methods, weight testing is the most common form of product conformity testing. Current weight conformity testing often involves passing the product through a specialized weight measuring device and then comparing the measured value with a predetermined standard value using a specific algorithm.

[0003] Typically, after products pass inspection, a specific number of qualified products are stacked and packaged for easy transport. However, current product inspection usually requires manual operation, which increases the labor intensity of personnel. Therefore, an automatic weighing and steering device was invented.

At the same time, by using adsorption to fix the product, it can quickly fix the product to a certain extent, and also make the sides of the product unobstructed, making it easy to pick up and preventing the product from falling, thus improving stability.

[0100] Working Principle: This invention is mainly used for weight detection and stacking of products on the production line. In the initial state, under the elastic force of the second support spring 55, the loading platform is at the calibrated height, and the lower end face of the pressure rod 22 is flush with the upper end face of the upper plate 11; under the elastic force of the first support spring 25, the pressure disc 23 is at the calibrated height, and the upper end face of the pressure disc 23 is flush with the lower end face of the upper plate 11; under the elastic force of the elastic pad 40, the second outer bushing 42 is at the calibrated height, and the second outer bushing 42 and the first outer bushing 41 are toothed and engaged, while the first inner bushing 51 and the second inner bushing 52 maintain a certain distance.

[0101] During operation, the product is transported by the conveyor line or robot to the first loading platform 211 of the automatic weighing and steering device. Under the action of the product's gravity, the second support spring 55 is compressed, and the first loading platform 211 moves downward along the groove of the central bearing column 54. The pressure rod 22, which is fixedly connected to the first loading platform 211, abuts against the upper surface of the pressure disc 23 through the annular groove 111 of the upper plate 11 and continues to move downward. The upper surface of the pressure disc 23 is compressed, and the first support spring 25 is compressed. The pressure disc 23 moves vertically downward under the restriction of the guide column 24. The rack 31, which is fixedly connected to the pressure disc 23, moves downward synchronously, driving the spur gear 32 to rotate, thereby driving the gear transmission shaft 33 to rotate. The helical gear 34 rotates synchronously. Through the helical gear transmission, the second helical gear 37 rotates, driving the second spur gear 39 on the gear transmission shaft 38 to rotate. Through the gear transmission, the central gear 30 rotates clockwise synchronously. The rotation of the central gear 30 drives the outer bushing 41 to rotate. Utilizing tooth engagement, the outer bushing 42 rotates clockwise in sync. Through the fixed connection of the connecting plate 43, connecting plate 44, and the spring tensioning shaft 45, the spring rotates clockwise, while the spring fixing housing 47 remains stationary. One end of the spring 46 is fixed, and the other end rotates with the spring tensioning shaft 45, thus tensioning the spring 46.

[0102] When the mainspring 46 is tensioned by the mainspring tensioning shaft 45, the inner bushing 52 moves downward synchronously with the pressure disc 23. Initially, the distance between the inner bushing 1 51 and the inner bushing 2 52 decreases, but they do not contact each other. This continues until the mainspring tensioning shaft 45 rotates 90° clockwise, at which point the inner bushing 1 51 and the inner bushing 2 52 contact each other, their teeth engaging. As the inner bushing 2 52 continues downward, the inner bushing 1 51 is compressed. This pressure is transmitted to the elastic pad 40 through the connecting plate, the mainspring tensioning shaft 45, and the mainspring base plate 49. The elastic pad 40 contracts under pressure, causing the inner bushing 1 51 to move downward. This causes the connecting plate 1 43 and the outer bushing 2 42, which is fixedly connected to the connecting plate 1 43, to move downward synchronously. The distance between the outer bushing 2 42 and the outer bushing 1 41 increases until they disengage. At this point, the mainspring 46 returns to its initial state from the tensioned state, causing the mainspring tensioning shaft 45 to rotate counterclockwise. This pressure is transmitted through the connecting plate... 44. Connecting plate 43 drives inner bushing 51 to rotate counterclockwise. Utilizing toothed engagement, inner bushing 52 rotates counterclockwise synchronously. Since the central column 53 and inner bushing 52 are connected by a key and keyway 531, they cannot rotate relative to each other. Therefore, the central column 53 rotates synchronously, driving the central support column 54, which is fixedly connected to it, to rotate counterclockwise. When the central support column 54 rotates 90° counterclockwise, the pressure rod 22, which was originally fixedly connected to the first loading platform 211, moves into the annular groove of the pressure disc 23. The pressure of the pressure rod 22 on the pressure disc 23 disappears. Under the elastic force of the support spring 25 and the elastic pad 40, the pressure disc 23, inner bushing 51, inner bushing 52, and rack 31 all return to the calibrated height. The toothed engagement between inner bushing 51 and inner bushing 52 disengages, and the central column 53 stops rotating. At this point, the first loading platform 211 rotates to the position of the original second loading platform 212, and the other loading platforms rotate 90° counterclockwise accordingly. The original fourth loading platform 214 rotates to the position of the first loading platform 211, ready to receive the next batch of products. After all loading platforms have completed loading the products, the pressure rod 22 corresponding to the fourth loading platform 214 will be restricted by the annular groove 111 on the upper plate 11, preventing the loading platform from rotating. At this time, a fixed number of qualified products on the loading platforms can be stacked.

[0103] This device uses the product's weight as the standard for detection. Only when the product weight reaches the predetermined standard value will the pressure disc 23 move downward until the outer bushing 41 and the outer bushing 42 disengage, thereby causing the central column 53 to rotate. If the product weight does not reach the standard value, the rotation of the central column 53 will not occur. This achieves the effect of automatically detecting whether the product weight is qualified.

[0104] The tooth profile mating in this device is only one form of clutch mechanism; other clutch mechanisms can achieve the same effect. This device uses four loading platforms as an example, and other specific numbers of loading platforms can achieve the same effect through this mode.

[0105] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
