In the prior art IC card automatic production, a plurality of IC cards can be fabricated into IC card weldments of different vertical and horizontal alignments, generally three rows, four rows, and five rows, such as 3*6, 3*8, 4*6, 4*8, 5*5, 5*8 and other specifications. The structure of each IC card on the IC card weldment basically comprises three parts: one is an IC card chip, the other is a coil, and the third is a paper card for fixing the IC card chip and the coil. In the automated production of IC cards, it is necessary to solder the two enameled wire lead wires of the coil to the pads of the IC card chip to enter the next production process.

The following is an example of a 5*5 IC card weldment to illustrate the structure of an IC card weldment.

Referring to Fig. 1, the size of the IC card weldment 100 of 5*5 is 46*30.5 cm (length * width = 18 inches * 12 inches), and the five rows of IC cards 101 are arranged vertically and horizontally on a plane. Each IC card 101 has a size of 7.5*4.5 cm, and a coil 102 is preset on the four outer sides of the paper card, and a chip 103 is preset in the lower right quadrant of the coil 102, and two turns of the coil 102 are drawn.

The prior art can automatically produce various IC card weldments, and the IC card weldment also needs to solder the two enameled wire lead wires of the coil to the pads of the IC card chip to become an usable IC card, for example, production. In the case of the 5*5-size IC card weldment 100 shown in Fig. 1, it is necessary to weld 50 of the solder joints.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described in the specification are to be construed as illustrative only and not limiting.

Referring to FIG. 1, the IC card automatic double spot welding apparatus of the present invention is for soldering two enameled wire lead wires 104A, 104B of the coil 102 of each IC card 101 on the IC card weldment 100 to the two pads 105A of the IC card chip. , 105B, and the automatic welding equipment provided for this welding process. Hereinafter, the related structure of the IC card automatic double spot welding apparatus of the present invention will be described by taking the automatic welding of the 5*5 IC card weldment as an example. The size of the 5*5 IC card weldment 100 is 46*30.5 cm (length * width = 18 inches * 12 inches), and the five IC cards 101 to be processed are arranged vertically and horizontally on a plane. Each IC card 101 has a size of 7.5*4.5 cm, and a coil 102 is preset on the four outer sides of the paper card, and a chip 103 is preset in the lower right quadrant of the coil 102, and two strips are drawn from the coil 102. The 0.08 mm enameled wire lead wires 104A, 104B are neatly placed on the pads 105A, 105B on both sides of the chip 103. Positioning holes 106A, 106B for positioning on the fixture are also provided on the 5*5 IC card weldment 100. Each of the pads 105A, 105B has a width of 1.0 mm, and the pitch of the two pads 105A, 105B is 5 mm. For convenience of explanation, the present invention refers to the arrangement of the IC card weldment 100 in the 46CM direction as a lateral arrangement, and the arrangement in the 30.5CM direction is referred to as a longitudinal arrangement. The IC card automatic double spot welding equipment of the present invention is to automatically weld 50 solder joints on the IC card weldment 100.

Referring to FIG. 4, in order to improve the welding efficiency, the IC card automatic double spot welding device of the present invention is designed to include a plurality of spot welding machine main body 402 and an IC card automatic spot welding work table 400, and the IC card automatic spot welding work table 400 is installed. The gantry frame 405 mounts five double spot welding heads 200 with power units side by side at the corresponding positions of the gantry frame 405 and the IC card chip 103 of the IC card weldment 100, and is mounted on each of the double spot welding heads 200. The two parallel electrode horns face the enameled wire lead wires 104A and 104B preset on the pads on both sides of the IC card chip 103, and the welding of one horizontal row of solder joints shown in FIG. 1 can be completed by one welding operation. That is, the welding of 10 solder joints required for the five IC cards 101 arranged in the horizontal direction is completed at one time. Of course, if the welding object is a 3*8 IC card weldment (that is, there are 3 IC cards 101 per horizontal row), only three double spot welding heads 200 with power units are required.

With the above-mentioned multi-point double spot welding head 200 capable of completing a full horizontal welding spot welding at one time, the present invention only needs to provide an automatic sliding table 404 capable of moving in the longitudinal direction to mount the IC card weldment 100, which can be Automatic welding of all solder joints on the 5*5 IC card weldment 100: If the interval between each soldering is set to 1 second, it takes only about 5 seconds to complete the 5*5 IC card as shown in Figure 1. The welding of the weldment 100 greatly improves the welding efficiency. In addition, since the present invention requires only one automatic slide table 404 to realize the movement of the IC card weldment 100 in one direction, compared with the prior art of two automatic slide tables that need to move in both the X-axis and the Y-axis directions, It not only has the advantages of simple structure, double the cost of automation equipment, but also effectively improves welding precision and welding quality.

In order to be able to realize the installation of a plurality of double spot welding heads 200 in a limited space, the spot welding machine main body must also be modified. Each of the prior art spot welder mainframes requires a large transformer to be installed in the mainframe including a pulse transformer, a power transformer, a set of large capacitors and an output control board. The size of the main chassis is usually 40*30. *25cm (length * width * height). If the structure of the existing electronic component automatic welding production device is used, it is necessary to install 10 40*30*25cm spot welding machine mainframes to achieve simultaneous welding of 10 solder joints, which is limited to only 46 cm of welding space. It is simply impossible to achieve. Therefore, the present invention proposes a structure of a double spot welding host. In the main box of the double spot welding mainframe, in addition to the two output pulse transformers installed side by side in the front side of the main box, including the power transformer, large power Only one of the other components, including the output control board, is installed, enabling a dual spot welder to provide two regulatable output currents. The size of the main box of the above double spot welding main machine is 30*45*25cm (length*width*height), which is equivalent to changing the original structure of the two main parts of the two spot welding machine to only one main size. The main chassis greatly reduces the space required for the double spot welding mainframe installation. When it is necessary to install five double spot welding mainframes on the IC card automatic welding equipment, the main equipment box can be arranged by two-layer installation method in which the bottom layer is arranged in three layers and the upper layer is arranged in two, and then each double spot welding main body is passed through the soft one. The output cable is electrically connected to the corresponding double spot welding head 200, so that the original 10 spot welding machine main body can be installed in the limited space of the IC card automatic double spot welding device of the present invention. The double spot welding machine and the double spot welding head 200 with the power unit constitute the double spot welding automatic spot welding machine proposed by the present invention.

The double spot welding host proposed by the invention installs two output pulse transformers in one main box, and other components including a power transformer, a large capacitor and an output control circuit board are combined into one, which is conceivable as two output pulses. The power supply part and the control part of the transformer are the same set of large capacitors, the same power transformer and the same output control circuit board, so the two output currents of the double spot welding host are easier to achieve. In addition, the structure and function of the double spot welding main body corresponds to the double spot welding head 200 with the power unit, so the structure of the double spot welding main body is very simple and reasonable, and is considered from the size and weight of the 40KG. Also suitable for packaging, transportation and installation, these are the advantages or technological advancements of a double spot welding machine.

It should be noted here that the IC card automatic double spot welding equipment of the present invention mainly requires that the length of the double spot welding main body (ie, the lateral direction corresponding to the IC card weldment 100) be narrowed so as to be able to be placed in a welding space corresponding to only 46 mm. The requirements of the spot welder mainframe, but because the workbench of the spot welder mainframe can have a lot of space in depth, whether it is a narrow single machine or a narrow multi-machine Or the spot welding machine host is placed on the double spot welding host to place two output pulse transformers, or / and two power transformers, or / and two sets of large capacitors, or / and two output control circuit boards, The above structures are all equivalent structures of the present invention and should fall within the protection scope of the present invention.
