Description

Fully automatic continuous roll surface treatment production line technical field

The invention belongs to the technical field of continuous roll type surface treatment production lines, in particular to a fully automatic continuous roll type surface treatment production line.

Background technique

In the field of electronics industry, in the process of continuous roll surface treatment production line, first of all, the surface treatment material should be continuously introduced into the surface treatment production line through the unwinder. With the rapid development of the electronics industry, many continuous metal electronic products are constantly developing towards miniaturization and miniaturization, and the processing speed of the continuous surface treatment production line is getting higher and higher. However, in the actual surface treatment production, the traditional manual processing is used for splicing the end of the previous roll and the head end of the next roll of metal materials, and the following problems will occur in manual operation: First, the splicing operation is not completed, resulting in the surface treatment production line The automatic shutdown will make all products in the surface treatment production line scrapped, causing great losses and reducing the production capacity of the production line; second, in the joint operation, due to improper operation, the raw material will scratch the operator's hand and cause work accidents; third Third, during the high-speed operation of the surface treatment production line, in order to prevent operation errors, the manual joint operation of the product requires sufficient time, so that the design requirements for the buffer machine are getting higher and higher, and the equipment mechanism is also becoming more and more complicated; Fourth, continuous terminals The smaller and thinner the product material, the easier the manual joint operation will be deformed, which will affect the product quality; Fifth, the manual joint of the product is not firm, and it is easy to fall off during the high-speed production process, resulting in shutdown and shutdown; Sixth, the precision of the manual joint is poor, and the product positioning hole cannot be Accurate overlapping causes the positioning of the surface treatment product and the precious metal fixture to not match, causing the position of the precious metal coating to shift, causing the product to be scrapped; Seventh, the product joint is firmly connected with rivets at the position of the positioning hole connection belt, while the metal terminal part is not very connected. If the terminal is firmly scattered, scraping against the guiding jig in the process slot will cause the product to deform and stop production.

In view of the above-mentioned joint operation problems between metal materials, only to reduce the number of shutdowns in the production of continuous metal terminal products, prevent various industrial accidents of operators, and reduce product scrapping losses caused by product deformation and inaccurate positioning holes, Only in order to improve the production efficiency of the continuous roll surface treatment production line and greatly reduce the production cost of continuous metal terminals, the research and development of a fully automatic continuous roll surface treatment production line is an urgent topic to be solved in the surface treatment industry.

In view of the above problems to be solved, thin copper, thin copper alloy and thin stainless steel strips are used as raw materials for continuous metal terminals obtained by precision stamping and processing, and thin copper, thin copper alloy and thin stainless steel strips are used for reel type. The operation mode of the feeder instead of manual has been continuously researched and improved, and at the same time, the joint operation between the metal material disk and the disk has also been continuously improved.

The end faces and end faces of the two steels are connected in parallel, and the joints are fixed with the same small steel plate and steel ring, and then the small steel plate is heated with a gas flame until it melts. After cooling, the 2 steel pieces are joined together. However, when this technology is applied to a continuous roll surface treatment line, it requires a long operating time and uses a gas flame, which is not applicable to a continuous roll surface treatment line.

In Patent Document 2 (JP 2005-75292 A), a material joining method is described in which metal foils or heat-resistant plastic films are joined by thermocompression technology. However, due to the use of thin copper, thin copper alloys and thin stainless steel in continuous coil surface treatment lines, hot pressing technology is not suitable for material joint connection of continuous coil surface treatment lines.

In Patent Document 3 (JP 2002-322440 A), there is disclosed a method for preventing the adhesive from leaking when the end of the previous roll and the head end of the next roll are connected with an adhesive tape in the production of continuous plastic film coating. Leakage to ensure the normal operation of production methods.

In Patent Document 4 (JP 6660533 B2), a metal welding structure is provided, and the required irradiation energy can be adjusted and set by the laser output with respect to the welding progress direction and the cross-section in the right-angle direction. However, the expensive laser equipment limits its application in continuous roll-to-roll surface treatment production lines.

The use of adhesive tape to connect the conductive plastic film to the surface treatment production through the corrugated butt joint device can be carried out continuously.

In Patent Document 6 (JP 5761124 B2), a continuous surface treatment apparatus and a continuous surface treatment method for continuously performing surface treatment on a roll-type conductive flexible substrate are provided. However, in this patent, how to connect the end of the previous roll of the conductive soft substrate and the head end of the next roll to ensure the continuous production and processing method of the conductive soft substrate is not described.

In Patent Document 7 (CN 206305604 U), an ultrasonic spot welding machine feeding device is provided. In the production of a roll-type surface treatment production line, the end of the previous roll and the head end of the next roll of the surface-treated metal material are processed. Joint welding process. Ensure the stability of product quality and improve the production efficiency of surface treatment.

Patent Documents 1 to 6 provide a variety of joining methods between metal material discs, but all design principles and their practical operations cannot solve the requirements for automatic joining operations in a fully automatic continuous roll surface treatment production line. Research and development of automatic The production equipment for automatic welding of unwinding and metal material joints has become the biggest difficulty in the production of fully automatic continuous roll surface treatment production line equipment, and is a major issue to be solved urgently in the surface treatment industry.

In the previous report of Patent Document 7 (CN 206305604 U), an ultrasonic spot welding machine feeding device is provided. In the production of a continuous roll-type surface treatment production line, the end of the previous roll and the next roll of the surface-treated metal material are The tip of the joint is welded. It can ensure the stability of product quality and improve the production efficiency of surface treatment.

However, the welding process is still a manual operation, so there are still some problems in the joint operation of the continuous terminal product material, which greatly limits the application of the welding equipment in the fully automatic continuous surface treatment production line.
