Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to a method for partially plating plated objects, such as strip-shaped plated objects such as %KIC lead frames, and for transferring plated objects to and from the main body of a plating apparatus. Regarding mounting equipment.

(B) Conventional technology and problems In order to efficiently plate a large amount of plated items, there are various conventional techniques in which the plated items are transported on a plating line and subjected to pre-treatment, plating treatment (for example, partial plating treatment), post-treatment, etc. However, depending on the shape and structure of the plated product, normal conveyance means cannot be used, and therefore racks and other equipment are required for special cases.Also, when spray plating is adopted as the plating process, it is difficult to use normal means of conveyance due to the shape and structure of the plated product. It is necessary to transfer the plated object onto the plating equipment and take it out to the delivery line, and when the plated object has a rectangular shape such as an IC lead frame, it is necessary to transfer the plated object onto the plating equipment and take it out to the delivery line. It is necessary to process multiple plated items at the same time. Therefore, the applicant arranged and placed a plurality of strip-shaped plated objects on a trolley in advance, transported the plated objects together with the trolley, and performed pre-treatment, plating treatment, and post-treatment to automatically process a large number of plated objects. See Japanese Patent Application Laid-Open No. 1983-99127, which previously proposed an apparatus for efficiently plating. Although this proposal significantly increases the processing speed, it is difficult to increase the processing speed any further because the plated material is transported via a trolley. For this reason, the present applicant has newly investigated a technique for plating a plurality of plated items at the same time by aligning and transporting the plated items directly on a roller conveyor without using a trolley.

Therefore, the applicant previously proposed a plated material transfer device as shown in FIGS. 1 and 2. This transfer device 1 is entirely movable forward and backward along a horizontally elliptical trajectory XK, and is provided with a plurality of first claw bodies 3 for holding plated objects 2, each of which holds a plurality of plated objects 2 horizontally at the bottom. A first chuck device 5 is provided on the entrance side for holding and simultaneously transferring a plurality of plated articles 2 from the pretreatment device 4, and a first chuck device 5 for holding both top and bottom surfaces of the front end of each plated article 2 is provided on the entrance side. 2-claw body 6
A second chuck device 8 is provided on the output side for taking out a plurality of plated products 2 to a post-processing device 7.

In the transfer device 1 according to this proposal, the first chuck device 5 supplies the plated object 2 to the plating device main body 9 while drawing a horizontal elliptical trajectory X, so a considerable improvement in speed can be expected. The two-chuck device 8 is also expected to have the advantage of being able to discharge the plated material 2 from the plating device main body 9 at a considerable speed, but recently there has been a demand for higher speed plating processing, and it is fundamentally necessary to meet this demand. It was necessary to change the method of transferring plated material 2.

Furthermore, out of the parallel plated items 2, the plated items on one line have a different width size than the plated items on other lines, and the versatility that can handle this with one transfer device is required. There is.

(c) Purpose of the invention Therefore, in this invention, the supply of plating material to the main body of the plating apparatus and

In addition, 61 in FIG. 9 indicates a gate-shaped base frame, which supports the pressure cylinder 62, press block 63, etc., and rotates via the main roller 65 and sub roller 66 provided on the leg frame 64. , press equipment 4153
The whole can be moved to the right in FIG. 3 and returned to the left. Furthermore, 67 in FIG. 8 is a stopper;
8 is a sensor, which is a component of the roller device 21.

Next, the action will be explained.

[Entry of plated object 22] Plated object 22Fi paralleled in the left and right direction'! f. First, it is received into the roller device 21 from the left side in FIG. Each roller 49 rotates via a motor 59 and a timing belt 60, and the plated object 22 is placed and transferred on a pass line 50 on each roller 49 and guided to a predetermined position K determined by a stopper 67, and a sensor 68 The presence of the plated object 22 is checked and a signal is transmitted to the chuck device 12.

Note that when the plated article 22 enters the roller device 21, the trumpet-shaped introduction portions 48 of the pair of left and right guide frames 47 attached to the lower portions of the holders 27a and 27b move the plated article 22 into the roller device 21.
The chuck 32 of the chuck device 12 reliably picks up the plated article 22 by guiding and regulating the advancing state of the plated article 22 so that the plated article 22 is positioned in a position where it is easy to hold the plated article 22.
2 is transferred.

[Operation of the chuck device 12] Upon receiving a signal from the sensor 68, the "rotating means" first functions. As shown in FIGS. 10 to 12, the pressure cylinder 40 works, the rod 38 moves, and the pinion 36 that engages with the rank 37 rotates. Accordingly, when the left and right chucks are installed, the shafts 60 are moved inwardly toward each other. [Figure 12]
The claws 34 of the chuck 32 rotate the left and right sides 22a, 22b of the plated object 22 from diagonally downward and pick it up.
FIG. 15], and then the plated object 22 is held in a horizontal state [FIG. 13]. At this time, the difference portion 35 locks the left and right sides 22a and 22b of the plated object 22, thereby making the holding state more reliable.

By such lifting and holding, the plated object 22 is instantaneously received by the roller device 21 and the rechucking device 12.

This kind of action is for the first chuck device 2B on the inlet side of the plating apparatus main body 14, and the second chuck device 24 on the -1 outlet side uses a similar action to remove the plated object 22 which has been partially plated by spraying. is lifted up and held from the upper lid 52 by the chuck 62 of the second chuck device 24 (for convenience, the chuck 62 of the first chuck device 23 is designated by the same reference numeral in FIG. 9). Therefore, all plated objects 22 in a straight line are subjected to the same lifting and holding process on both the entry side and the exit side.

[Movement of frame 11] Next, the "moving device" functions to move the frame 11.

That is, the rotation of the motor 20 is transmitted to the ball screw 17 via the belt 19, and as shown in FIGS. The guide 18 is forced to move to the right in Figure 4. The support frame 13 and the frame 11 are
Since these are connected, the support frame 16 and the frame body 11 move to the right in FIG. 4 via the pair of left and right shafts 16 and the slide bushes 15 guided by them. This movement manifests itself as switching of the chuck device 12 on the inlet and outlet sides of the plating apparatus main body 14. That is, the first chuck device 26 on the entry side is placed on top of the upper lid 52, and the second chuck device on the exit side is placed on top of the upper lid 52.
The chuck device 24 reaches to the right in FIG. 3 [the imaginary line position in FIG. 3].

[Operation of the chuck device 12 again] Contrary to the above, when installing the pair of left and right chucks, the shaft 60 is rotated, and the chuck 32 is opened, and the plated object 22 that was being held is unlocked, and the upper cover 52 is removed. Allowing the plated object 22 to fall upward under its own weight [first chuck device 26 on the entry side], while removing the plated object 22 upward to the post-processing device [not shown] [second chuck device on the exit side] 24] will be carried out. That is, the plating material 22 is supplied to and discharged from the plating apparatus main body 14 almost simultaneously.

[Returning movement of the frame 11] The “moving device” operates again, and the frame 11 moves to the fourth position, contrary to the previous movement.
The first chuck device 23 on the entry side moves back to the right in the figure.
The second chuck device 23 on the exit side waits for and receives the new plated material 22 entering a predetermined position on the roller device 21 and performs the same action as before, and the second chuck device 23 on the exit side waits for and receives the new plated material 22 that enters a predetermined position on the roller device 21. The same operation as above is performed in order to wait for and receive the plated object 22 that has been plated.

[About width adjustment]

In the above operation, a "width adjustment means" is used to adapt the chuck device 12 to plated objects 22 of different width sizes. That is, as shown in FIGS. 10 to 12, when the first rotating body 44 is rotated, the shaft 4
The pair of left and right holders 27&, 27b, which are rotated and screwed into the reverse threaded part 43, are opened or closed while the bar material 25K is mounted, and the pair of left and right The chuck is attached to the shaft 30, the gap between the left and right channels 2620, and the trumpet-shaped introduction part 48.
At the same time, the interval between the guide frames 47 forming the plated object 22 is adjusted in accordance with the width of the plated object 22.

The function of the "rotating lifting means 51" has been previously described in detail, so a description thereof will be omitted.

(F) Effects of the Invention Since the plated material transfer device according to the present invention has the content described above, it can be expected to have many excellent effects, the main effects of which are listed below. Then, it is as follows.

(,) Since the frame can simultaneously change the relative position of the chuck devices arranged on both front and rear sides of the frame to the plating apparatus main body, it is possible to change the relative position of the chuck devices on both front and rear sides of the frame body, thereby making it easier to transfer or feed plated objects to the plating apparatus main body. - The speed of ejection can be increased; (b) The frame body is simply able to move forward and backward in the horizontal plane and can be switched freely; it does not move up and down; and the chuck of the chuck device placed on the frame body is plated. Since the left and right sides of the plate are rotated to pick up and hold the plated item, it is possible to receive the plated item without moving up and down, and there is no need to draw a horizontal oval trajectory like in the past, so it is possible to pick up the plated item without moving up and down. (c) The chuck device can adjust the distance between the left and right sides of the chuck, making it versatile for handling plated items of different widths.
Furthermore, since the width of each chuck of the multiple chuck devices can be adjusted independently for each row depending on the number of parallel plated objects, it is possible to handle the transfer of plated objects of different sizes depending on the line. (d) Above (,) As a synergistic effect of (c), even if the plating speed of the plating apparatus main body is made faster than before, the plating material can be sufficiently supplied and discharged, and the efficiency of the plating process can be improved accordingly.
