Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
For a clearer understanding of the technical solutions in the present application, first, a description will be given of detection scenarios, which are various types of spray heads, wherein a rotatable part is mounted at a nozzle of one type of spray head, the part can swing under an external force, and the nozzle can be adjusted, for example, opened and closed, when different areas on the part are located at the nozzle.
When the part is pushed to swing, the relative position of the part and the nozzle is changed, so that the pushing force is required to be neither too large nor too small, the pushing force is difficult to push when a user uses the nozzle due to too large pushing force, and the part is uncontrollably swung when the pushing force is too small, so that the working state of the nozzle is unstable, for example, the sudden injection amount is reduced when the nozzle is used.
Of course, this detection scenario is not exclusive, and other similar scenarios are possible, such as detecting the trigger force of a button and detecting the trigger sensitivity of a trigger.
Referring to fig. 1, a sliding force detecting system disclosed in the embodiment of the present application includes a detecting table 11, a pressing device 13, a linear moving device 2, a force sensor 24, and a control portion, and specifically, a fixing cavity 12 is formed on the detecting table 11, and the fixing cavity 12 is used to fix a detecting element.
The detecting member is composed of a first portion and a second portion, and the second portion can move under the action of external force, and reference can be made to the spray head and the parts capable of swinging on the spray head mentioned above.
The shape of the fixing cavity 12 matches the shape of the first part of the test piece, so that when the first part of the test piece is placed in the fixing cavity 12, the inner wall of the fixing cavity 12 can be attached to part of the surface of the first part of the test piece, and then a pressure is applied to the first part of the test piece, so that the first part of the test piece can be pressed in the fixing cavity 12.
The above mentioned pressure is provided by a pressing device 13, the pressing device 13 is arranged on the detection table 11 and is used for applying pressure to the first part of the detection piece placed in the fixed cavity 12, for example, during the detection, the working end of the pressing device 13 is abutted on the surface of the first part of the detection piece; after the detection is finished, the working end of the pressing device 13 is separated from the contact with the first part of the detection piece, and the detection piece is taken out of the fixing cavity 12 by a worker.
Referring to fig. 2 and 3, the sliding force is the force required when the part on the spray head swings, and the specific detection is performed by the linear moving device 2 and the force sensor 24, the force sensor 24 is mounted on the linear moving device 2, and the linear moving device 2 can drive the force sensor 24 to move towards and away from the fixed cavity 12. During the approaching process, the detecting end of the force sensor 24 contacts the second part of the detecting member and applies a pushing force to the second part of the detecting member, and the pushing force simulates the pushing force applied to the parts on the sprayer when the sprayer is used by a user in a real use scene.
The force sensor 24 can detect the thrust value while applying the thrust, and the detected thrust value can be used for judging whether the detection piece is qualified or not, for example, the required range of the thrust value is 0.6-0.8 newton, and the detection value is 0.9 newton, which indicates that the connection of the first part and the second part of the detection piece is tight; the value of the test is 0.4 newtons, indicating that the first and second portions of the test piece are loosely connected.
It should also be understood that the thrust force exerted by the force sensor 24 on the part and the sliding force required by the part during sliding are both forces in nature and the same values, with different designations only for convenience of distinction.
The pressing device 13, the linear moving device 2 and the force sensor 24 are all controlled by the control part, that is, in the whole detection process, a worker only needs to place the first part of the detection piece in the fixed cavity 12 and take the first part out of the fixed cavity 12 after the detection is finished.
Of course, if the control part has a judgment function, that is, the detection result can be displayed to the worker by displaying the detection value or the traffic light (the red light indicates that the detection is unqualified, and the green light indicates that the detection is qualified), the unqualified detection pieces need to be screened out and placed separately after being taken out from the fixed cavity 12.
On the whole, the sliding force detection system disclosed in the embodiment of the application detects the sliding force of the detection piece on the spray head in an automatic detection mode, and the whole detection process is based on the same detection standard, has higher automation degree and can meet the detection requirement in the large-scale production process.

In some possible implementations, the driver 131 uses a pneumatic cylinder or an electric cylinder.
Further, referring to fig. 3, a locking groove 133 matching with the first portion of the detecting member is added to the cantilever 132, and the locking groove 133 serves to increase a contact area between the cantilever 132 and the first portion of the detecting member, so as to improve the fixing effect.
