Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal part detection, in particular to automatic weighing and detection equipment for sheet metal parts. Background Art

[0002] In the prior art, sheet metal inspection is not only an appearance inspection, but also a weight inspection. There are requirements for the weight of each sheet metal part. However, the existing inspection method is to check and inspect by manual weighing, which is inefficient, inconvenient to carry sheet metal parts, and consumes a lot of manpower and material resources.

[0003] In the patent document with the publication number CN212821193U, an automatic weighing and testing device for sheet metal parts is disclosed, including an equipment frame, a conveying mechanism fixedly mounted on the equipment frame, and a PLC controller for controlling the overall operation process. The equipment frame is equipped with a conveying mechanism, and the conveying mechanism includes a first conveyor belt arranged at the front end of the equipment frame, a second conveyor belt arranged at the middle end of the equipment frame, and a third conveyor belt arranged at the rear end of the equipment frame. The bottoms of the first conveyor belt, the second conveyor belt, and the third conveyor belt are all fixedly mounted with a rotating motor through a rotating motor fixing seat. The bottom of the rotating motor fixing seat arranged at the bottom of the second conveyor belt is also fixedly mounted with an electronic weighing device. A waste plate recovery box is arranged at the front end of the third conveyor belt. In the process of implementing this technical solution, the inventor found that there are at least the following problems in the prior art:

[0004] When the above device is actually used, although it is convenient to detect whether the weight of the sheet metal parts meets the standard, due to the different standard weights of different sheet metal parts, it can only detect a single type of sheet metal parts, which is inefficient and inconvenient to use. In addition, the sheet metal parts are pushed into the recycling bin by the waste material ejecting cylinder, which can easily cause the sheet metal parts to collide with the recycling bin, causing damage to the sheet metal parts and the recycling bin, affecting the subsequent processing of the sheet metal parts and the service life of the recycling bin, and causing inconvenience to the staff.

[0005] It should be noted that the information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to a person skilled in the art. Therefore, the above content belongs to the technical cognition of the inventor and does not necessarily constitute prior art. Utility Model Content

[0011] Preferably, first baffles are fixedly connected to both sides of the top of the fixing frame, and a second baffle is fixedly connected to the center of one side of the top of the fixing frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The automatic weighing and testing equipment for sheet metal parts has two feed troughs inside the feed hopper. Sheet metal parts of two different specifications are placed in the feed hopper, and slide into the discharge troughs on one side of the two conveyor belts through the inclined feed trough, and then slide into the conveyor belt through the inclined discharge trough. When the sheet metal parts pass through the electronic weighing device in the discharge trough, the sheet metal parts are weighed, and then the sheet metal parts are transported through the conveyor belt. If the weight of the sheet metal parts is lower than the set standard, the electronic weighing device transmits a signal to the electric push rod through the PLC, and the electric push rod drives the push plate to move and push the unqualified sheet metal parts into the collection box, thereby achieving the effect of weighing and testing sheet metal parts of various specifications.

[0027] The bottom of the fixing rod 34 is fixedly matched with the top of the spring 33 , and the outer sides of the buffer plate 35 and the rubber pad 36 are slidably matched with the inner wall of the collection box 31 .

[0028] It should be noted that: there are two feed troughs 5 inside the feed hopper 4. Two sheet metal parts of different specifications are placed in the feed hopper 4, and slide into the discharge troughs 6 on one side of the two conveyor belts 2 through the inclined feed troughs 5, and then slide into the conveyor belt 2 through the inclined discharge troughs 6. When the sheet metal parts pass through the electronic weighing device 7 in the discharge trough 6, the sheet metal parts are weighed, and then the sheet metal parts are transported through the conveyor belt 2.

[0032] The working principle of the sheet metal automatic weighing and testing equipment provided by the utility model is as follows:

[0033] When in use, two feed troughs 5 are provided inside the feed hopper 4. Two sheet metal parts of different specifications are placed in the feed hopper 4, and slide into the discharge troughs 6 on one side of the two conveyor belts 2 through the inclined feed troughs 5, and then slide into the conveyor belt 2 through the inclined discharge troughs 6. When the sheet metal parts pass through the electronic weighing device 7 in the discharge trough 6, the sheet metal parts are weighed, and then the sheet metal parts are transported through the conveyor belt 2. If the weight of the sheet metal parts is lower than the set standard, the electronic weighing device 7 transmits a signal to the electric push rod through the PLC. 8. The electric push rod 8 drives the push plate 9 to move and pushes the unqualified sheet metal parts into the collection box 31, so as to achieve the effect of weighing and testing sheet metal parts of various specifications. When the sheet metal parts enter the collection box 31, they first fall on the rubber pad 36 on the top of the buffer plate 35, which preliminarily buffers the impact force of the falling sheet metal parts, and the spring 33 and the fixing rod 34 inside the fixing cylinder 32 further buffer the impact force, thereby reducing the impact force of the falling sheet metal parts and protecting the sheet metal parts.

[0034] It should be noted that the connection control method of the electronic scale, PLC controller and electric push rod is an existing technology, which can be learned by technical personnel in this field through technical manuals or through conventional experimental methods.
