Description

Plasma generator for processing a shoe material and processing method thereof

The invention relates to a surface treatment method for a shoe material, in particular to a plasma generator for treating a shoe material and a treatment method thereof.

According to the shoe, many shoes are sewn and glued, and on the surface of the shoe to be glued, it must be processed first in order to successfully complete the bonding operation.

However, as far as the current upper is concerned, it is necessary to carry out the surface roughening treatment, and then the surface treatment with the treating agent, in order to apply the water-based glue for adhesion, and the operations before the sizing are laborious and time consuming. .

Due to the need to use a large number of treatment agents, and the treatment agents are mostly solvent systems, which have a great impact on environmental protection, countries around the world have already specified the specifications for reduction.

In order to solve the above problems, the industry has developed the use of low temperature plasma to treat the surface of the shoe material, such as CN102631052A, CN102754968A, CN102008153A, etc., wherein: CN102008153A patent discloses a plasma shoe sole processing technology method and equipment, including a plasma a generator discharge channel and a vertical or horizontal working turntable, the work turntable is provided with an upper socket The pole and the sole tray are used for placing the upper or the sole, and the upper surface of the upper is treated by plasma discharge. Although the upper processing method can solve the prior art problems, it cannot be processed for a curved surface or a relatively solid upper.

The CN102754968A patent discloses a method for pre-bonding a shoe material, comprising placing the shoe material in a vacuum chamber, feeding a second working gas, and performing plasma when the gas pressure of the second working gas reaches 0.01-2000 Pa. Body discharge, the shoe material is activated. Although this method can solve the prior art problems, the method must be carried out in a vacuum chamber, which has high technical difficulty, expensive equipment, complicated process, slow speed, and must use expensive gas, increase the cost of the process, and the gas must be added. The pressure is stored, and the use of high pressure gas cylinders is dangerous.

CN102631052A discloses a shoe material surface low temperature plasma discharge processing device, comprising a frame, which is provided with a conveying mechanism, a heating system, a plasma processing system and an ozone discharging system, which are mainly made of a conveying mechanism. It is transferred to the heating system and then sent to the plasma processing system for surface treatment. In this way, the shoe material must be heated first. When the shoe material is placed at a high temperature, it is easy to change in quality (such as deformation, discoloration, rough surface), burning or emitting toxic gas, etc., and the quality is difficult to control. Moreover, the method can not handle the three-dimensional or curved shoe material, and the utility of the shoe is low in practicality.

In addition, the plasma generators disclosed in the above three patents are fixed, and this method is only applicable to flat shoe materials, and cannot be processed for the processing of the three-dimensional upper.

Taiwan Bulletin No. 201714731 provides a multi-axis automation The sole processing equipment and the processing method mainly use an outer profile measuring module to obtain the shoe parameters of the shoe material (sole) outer size and height position relationship, and a control module reads and controls a multi-axis mechanical arm and the A plasma processing module on the robot arm performs plasma treatment on the shoe material, and the nozzle of the plasma processing module is a small tubular body capable of emitting plasma of about 4 mm length and being attached to the surface of the shoe by the nozzle. The inventive method first plans a surface treatment path that is circumferentially wrapped around the sole assembly and then advanced from one end of the sole assembly to the other end of the sole assembly in a meandering manner so that the surface treatment path ends in the sole The other end of the component. The problem of the invention is as follows: 1. The plasma nozzle of the plasma processing module is a conventional needle (tube) nozzle, so the surface treatment path must be planned. The method and equipment are not applicable to a shoe material as shown in FIG. The high three-dimensional portion of 91, especially in the high wall 92 portion of the shoe material and the recessed portion 93. 2. The method and equipment are processed according to the planned surface treatment path, so the stroke is very long, and the processing time is too long and too slow, plus the measurement time and planning time, so it is not economical. 3. The method and equipment adopt multi-axis robot arm, CCD camera and laser range finder, etc., and the equipment is expensive. 4. The device and method can only handle flat and low-dimensional uppers, and can not be processed for high-dimensional uppers.

In addition, Taiwan Application Nos. 105139812 and 106104419 are a shoe surface modification processing device and a processing method proposed by the applicant, and the devices and methods proposed by the two applications do not require the use of a CCD camera and a laser range finder. Measuring the parameters of the shoe's outer dimensions and height position, and not planning the surface treatment path, it can improve the problem of too slow processing. However, the two applications are still However, it is necessary to use a multi-axis robotic arm to process the concave and convex solid parts, or it is expensive to have equipment, and the surface position of the high-dimensional part and the high wall in the shoe material is processed by a multi-axis mechanical arm, and the effect is obtained. It is still not clear, so it is necessary to improve it. After more than two years of continuous improvement and testing, the invention has been produced.
