Description

Technical Field

[0001] The invention relates to a smart card manufacturing device, in particular to a plate material positioning composite welding device. Background Art

[0002] In the production process of contactless smart cards, the following processing steps are usually required: laser drilling process, winding process, chip welding process, ultrasonic composite welding process and cutting process; after the above processing steps, an independent smart card sheet unit is formed to provide semi-finished raw materials for subsequent other processing.

[0003] Existing ultrasonic composite welding devices, such as the invention patent application with application publication number CN107932917A, discloses "an ultrasonic composite device for contactless smart cards", which includes a frame, an ultrasonic bracket arranged on the frame, a welding slide assembly arranged on the ultrasonic bracket, two ultrasonic welding heads arranged at both ends of the welding slide assembly, a welding vertical power mechanism for driving the welding slide assembly to move up and down on the ultrasonic bracket, and a PVC covering sheet conveying mechanism for conveying the PVC covering sheet to the composite welding station; wherein, the two ultrasonic welding heads are connected to the ultrasonic equipment; and a welding head guide assembly for guiding the welding slide assembly to move on the ultrasonic bracket is provided between the ultrasonic bracket and the welding slide assembly. The present invention can convey the PVC covering sheet to the composite welding station, and weld the PVC covering sheet with the PVC sheet that has been wound to form a smart card sheet, so as to ensure that the coil on the PVC sheet will not be exposed, which is convenient for subsequent processing and transportation.

[0004] However, the ultrasonic compound device of the above-mentioned contactless smart card still has the following shortcomings:

[0005] During the compounding process, the ultrasonic compounding device of the contactless smart card conveys the wound PVC sheet and the PVC covering sheet to the compound welding station through the sheet conveying mechanism. At this time, the PVC covering sheet is located above the wound PVC sheet; then, the welding vertical power mechanism drives the welding slide assembly to move downward, so that the two ultrasonic welding heads arranged on the welding slide assembly move downward at the same time, so that the ultrasonic welding heads perform compound welding processing on the positions to be welded on the PVC covering sheet, and finally the wound PVC sheet and the PVC covering sheet are welded together to form a smart card production sheet; compound welding After the processing is completed, the welding vertical power mechanism drives the welding slide assembly to move upward, so that the two ultrasonic welding heads move upward and leave the processing position to be welded; then, the sheet conveying mechanism simultaneously conveys the smart card production sheet formed after the processing forward a certain distance, so that the next welding position on the rear PVC covering sheet is conveyed to the composite welding station; repeat the above-mentioned composite welding processing steps to complete the welding process; and so on, by synchronously conveying the PVC covering sheet and the wound PVC sheet to the composite welding station and performing composite welding processing, the composite of the PVC sheet and the PVC covering sheet is completed. In this process, since the wound PVC sheet and the PVC covering sheet are made of coils, during the entire welding process, when certain factors (such as vibration, wind force) cause the position of the wound PVC sheet and the PVC covering sheet to shift, the composite welding fails and affects the subsequent welding position shift, thereby affecting the production quality of the contactless smart card; in addition, the above-mentioned ultrasonic composite device can only weld a PVC covering sheet and a wound PVC sheet, resulting in the inability to completely cover the wound PVC sheet, which is easy to cause damage to the wound PVC sheet in subsequent processes, affecting the quality of the product. Summary of the invention

[0006] The purpose of the present invention is to overcome the above-mentioned problems and provide a sheet positioning composite welding device, which can cover the wound sheet up and down, that is, the bottom material is placed under the wound sheet, and the surface material is placed above the wound sheet, and then the three sheets are composite welded; in addition, the device can position the bottom material, the wound sheet, and the surface material, so that the sheets are arranged neatly and the position is accurate, thereby improving the quality of the composite welding of the sheets, thereby ensuring the production quality of contactless smart cards.

[0007] The purpose of the present invention is achieved through the following technical solutions:

During this process, the positioning plate contacts the side edges of the three sheets, pushing the three sheets to move toward the positioning bar until the other side of the three sheets contacts the positioning bar, and the sheets are moved in the X-axis direction or Y-axis direction based on the positioning bar. The three sheets are positioned and corrected in the axis direction, wherein two groups of positioning mechanisms can be provided, and the two groups of positioning mechanisms are arranged at 90° to realize the positioning of the three sheets in the X-axis direction and the Y-axis direction; then, the welding drive mechanism drives the welding head to move downward to perform composite welding on both sides of the three sheets, and finally, the welding drive mechanism drives the welding head to move upward. At this time, since the three sheets are clamped by the clamping drive mechanism, the welding head will not lift up the sheets during the upward movement, so that the welding head is separated from the sheets; finally, the clamping drive mechanism drives the clamping part to move upward, and the platform drive mechanism drives the sheet placement platform to move, so as to transport the composite welded sheets to the next station.

[0015] In a preferred embodiment of the present invention, the positioning mechanism is divided into two groups, and the two groups of positioning mechanisms are arranged at 90 degrees.

In this process, the card reader reads the chip information in turn, and the detector judges the welding quality of the weld when it reaches the welding point position. After the detection is completed, the card reader and the detector are reset to complete the quality inspection.
