Description

Technical Field

[0001] The utility model relates to the field of suction cup spacing equipment, in particular to an automatic suction cup spacing mechanism. Background Art

[0002] A suction cup is a pendant that uses the difference in internal and external atmospheric pressure to attach to an object, or a tool for grabbing objects. Its working principle is that when the suction cup contacts the surface of an object and forms a sealed space, air is drawn in to form a negative pressure area, which will generate an adsorption force, causing the object to be tightly adsorbed on the suction cup.

[0003] At present, suction cups are usually used on smartphone holders. The existing smartphone holder is a mobile phone holder that can be used in multiple scenarios and can be picked up and placed at any angle. One side uses an electric-driven vacuum suction cup to adsorb the smooth vacuum air pump and the intelligent pressure monitoring system automatically identifies high and low pressure states and automatically stops or starts. The other side uses 16 strong neodymium magnets for adsorption. It is suitable for mobile phones with magnetic rings and magnetic sheet mobile phones, as well as iron surfaces. Both sides can adsorb mobile phones.

[0004] At present, the suction cups installed on the smart phone holders usually detect whether the product has been sucked or deflated through negative pressure sensors. When multiple groups of suction cups are tested, the servo motor is started, and the servo motor drives the belt assembly to drive the screw to rotate, so that the equidistant telescopic frames with equidistant distribution on the frame drive the vacuum suction cup assembly to move equidistantly along the screw trajectory. However, when the existing suction cups are spaced apart, the belts in the belt assembly will wear or become loose when the mechanical transmission components such as the belt assembly and the screw are in long-term operation or are subjected to external forces, resulting in inaccurate detection results of the suction cups, thereby affecting the quality and reliability of the products, and requiring frequent shutdowns to adjust or replace the belts, which will increase the downtime of the production line and reduce production efficiency.

[0005] Therefore, it is necessary to provide a new automatic suction cup spacing mechanism to solve the above-mentioned technical problems. Utility Model Content

[0014] Compared with the related art, the automatic suction cup spacing mechanism provided by the utility model has the following advantages:

[0015] Beneficial effects:

[0016] Through the arranged adjustment device, when the suction cup needs to be spaced apart, the driving part is started first, and the driving part drives the threaded rod to rotate.

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in, Figure 1 A structural schematic diagram of an automatic suction cup spacing mechanism provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure from another perspective is shown; Figure 3 for Figure 1 The schematic diagram of the cutaway structure shown; Figure 4 for Figure 3 The structural schematic diagram of the regulating device shown; Figure 5 for Figure 3 A schematic diagram of the structure of the fixing component shown.

[0025] In the specific implementation process, Figures 1 to 5As shown, the fixed bracket 2 is fixedly connected to one end of the mechanical arm, the inner wall of the fixed bracket 2 is fixedly connected to an adjusting device, and a plurality of suction cups 3 are fixedly connected to the bottom of the adjusting device. The suction cup 3 usually adsorbs the back of the mobile phone by magnetic attraction. The working principle of the suction cup 3 is as follows: when the suction cup 3 adsorbs the back of the mobile phone, in order to prevent the suction cup 3 from leaking and affecting the adsorption force of the suction cup 3, the control end of the pressure switch conduction circuit board starts or shuts down the air pump, and the air pump is started when the internal pressure of the air cavity drops, and the air pump is shut down when the internal pressure of the air cavity is large enough, so that the adsorption force of the suction cup 3 remains stable. The working principle of the negative pressure sensor is usually through The medium pressure acts directly on the diaphragm of the sensor, causing the diaphragm to produce a micro-displacement proportional to the medium pressure. This micro-displacement will change the internal resistance of the sensor, and then convert this displacement into a standard signal corresponding to the pressure through an electronic circuit. The negative pressure sensor is particularly suitable for measuring the pressure value when the measured pressure is less than the preset pressure value. During the suction stage, observe whether the signal output by the negative pressure sensor drops rapidly to the preset negative pressure value range and remains stable. This can determine whether the suction cup successfully adsorbs the workpiece. After maintaining the adsorption state for a period of time, observe again whether the output signal of the negative pressure sensor changes. If the signal rises suddenly, it means that the suction cup may have leaked. If a leak is detected, the severity of the leak can be judged according to the degree and speed of the leak, and corresponding measures can be taken to repair or replace the suction cup.
