Abstract
The invention discloses a novel sucker performance testing device. The device consists of a syringe, a pressure sensor, a tension generator, a flat plate, a displacement sensor and a measured sucker. According to the invention, the maximum adsorption force of the tested sucker under the condition can be obtained by measuring the reading of the tension sensor when the tested sucker just drops from the flat plate, and the maximum adsorption force of the sucker under different negative pressure conditions can be obtained by combining the reading of the air pressure sensor. The testing device is simple in structure and easy to operate and maintain.
Description
Technical Field
The invention relates to a performance testing device of a sucker, in particular to a performance testing device of a sucker with controllable adsorption force.
Background
The suction cup is widely applied to the field of automation as a vacuum equipment execution device. The common sucker discharges gas in an inner cavity by means of external force to form negative pressure so as to generate adsorption force, and the adsorption force can not be adjusted and controlled, so that the application mode of the sucker is relatively single. For the design and optimization of the suction cup with controllable adsorption force, a corresponding suction cup performance testing device needs to be provided so as to obtain the relationship between suction cup structure parameters, external control input quantity and the like and the adsorption force.
Disclosure of Invention
The invention aims to provide a performance testing device for a suction force controllable sucker.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the invention is composed of a syringe, a pressure sensor, a tension generator, a flat plate, a displacement sensor and a tested sucker.
The inside of the tested sucker is provided with a control cavity and a controlled cavity, the control cavity is connected with an external control air source, the controlled cavity is close to the adsorption plane, and the two cavities are separated by an inner membrane. During testing, the tested sucker is tightly attached to the flat plate, and the control cavity of the tested sucker is connected with the needle cylinder. The volume of gas in the needle cylinder is changed by changing the position of the piston of the needle cylinder, so that the volume of the control cavity is controlled by the needle cylinder, the vacuum degree in the controlled cavity is further changed, and the adsorption force between the tested sucker and the flat plate is adjusted. The vacuum degrees of the control cavity and the controlled cavity can be measured by a pressure sensor. The tension generator is used for pulling the tested sucker through the rope, and the adsorption force between the tested sucker and the flat plate can be measured by the tension sensor. The distance of movement of the piston within the barrel may be measured by a displacement sensor.
The invention has the beneficial effects that:
(1) the sensor can conveniently measure input and output signals, and experimental data are provided for comprehensively evaluating the adsorption performance of the tested sucker.
(2) The testing device is simple in structure, easy to maintain and convenient to use.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the technical solution adopted by the present invention to solve the technical problem is:
the performance testing device facing the suction force controllable sucker consists of a needle cylinder, a pressure sensor, a tension generator, a flat plate, a displacement sensor and the sucker to be tested.
The inside of the tested sucker is provided with a control cavity a and a controlled cavity b, the control cavity a is connected with the needle cylinder, the controlled cavity b is close to the adsorption plane, and the two cavities are separated by an inner membrane. During testing, the tested sucker is tightly attached to the flat plate, and the control cavity a of the tested sucker is connected with the needle cylinder. The volume of gas in the needle cylinder is changed by changing the position of the piston of the needle cylinder, so that the volume of the control cavity a is controlled by the needle cylinder, the vacuum degree in the controlled cavity b is further changed, and the adsorption force between the tested sucker and the flat plate is adjusted. The vacuum degrees of the control cavity a and the controlled cavity b can be measured by a pressure sensor. The tension generator arranged on the bracket pulls the tested sucker through the rope, and the adsorption force between the tested sucker and the flat plate can be measured by the tension sensor. The distance of movement of the piston within the barrel may be measured by a displacement sensor.
Fig. 1 shows that the piston of the syringe moves forward, the volume of air in the syringe decreases, and the volume of the control chamber a connected with the syringe increases to expand the inner membrane, resulting in the decrease of the volume of the controlled chamber b and the decrease of the adsorption force, and fig. 2 shows that the piston of the syringe moves backward, the volume of air in the syringe increases, and the volume of the control chamber a connected with the syringe decreases to contract the inner membrane, resulting in the increase of the volume of the controlled chamber b and the increase of the adsorption force. The state transition between fig. 1 and fig. 2 may embody the regulation process.
