Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical field of the invention This invention is for supplying a rectangular plated object such as a lead frame (hereinafter simply referred to as a "plated object") to a plating apparatus main body for plating processing. The present invention relates to a plated article transfer device, particularly a plated article transfer device with improvements in the shape and structure of the rollers and the positional relationship between the chuck and the rollers.

(b) Conventional technology and problems Recently, methods and devices for moving multiple plated items on a line and plating them simultaneously have been attracting attention, and how to efficiently transfer plated items from the input side to the main body of the plating equipment in a short time. Various considerations have been made regarding whether to load (supply) and also transfer (discharge) the plated articles that have been plated to the output side.

For example, as a conventional plated material transfer device, Fig. 1~
There is something like the one shown in Figure 3.

A plurality of horizontal rollers 3 are arranged above the entrance side of the plating apparatus main body 1 [left side in FIG. I am trying to move it to [predetermined position]. That is, the upper surface side of each roller 3 serves as a pass line 4 for the plated articles 2, and a large number of plated articles 2 form multiple rows when viewed from above and are translated on the rollers 3 (Fig. 1). ]. There is a stopper 6 at a predetermined position of the front roller 5, and the plated objects 2 stopped there are then simultaneously received by the chuck 8 of the chuck device 1 one by one in each row. By reciprocating between the rollers 5 and the plating apparatus main body 1, they are transferred (supplied) onto the plating apparatus main body 1 at the same time.

However, what about conventional plating like this? The transfer device uses horizontal rollers 3, and chucks 8
In order to avoid interference between the plated material 2 and the rollers 3, the chuck 8 of the chuck device 7 enters between the front rollers 5 from the left and right sides of the front roller 5 and clamps both the left and right sides of the plated object 2 during transfer. The chuck 8 is specified to be of a size and shape that can enter between the front rollers 5, and its lowering and rising positions are limited between the front rollers 5, and the chuck 8 is moved in the front-rear direction [in the direction of arrow A in FIG. 2]. Because the length of the plated object 2 changes and when transferring another type of plated object, it is difficult to hold the plated object 2 at a position that provides a balance that matches the length of the plated object 2. In this case, it is necessary to adjust the distance between the front rollers 5, etc., which is difficult and time-consuming. Further, it is necessary to use guide means (not shown) for regulating the position of the plated material 2 on the upper surface of the horizontal roller 3 so that the plated material 2 is not disorganized and misaligned.

Furthermore, in the case of a conventional plated material transfer device, the front roller 5
When transferring the plated object 2 to the shimetuki device main body 1,
A gate-shaped trajectory as shown by arrow B in FIG. Since the transfer is performed in a trajectory of placing the material on the upper lid 9 which also serves as a mask → returning and raising the chuck 8 → returning and retracting the chuck 8, there is a problem that it takes time.

In the figure, reference numeral 10 indicates a suppression plate of the press device, reference numeral 11 indicates a nozzle for spraying a plating solution, and reference numeral 12 indicates a plating solution spray opening.

(C) Purpose of the Invention This invention is designed to enable the position of a chuck to be changed in order to hold plated objects of different lengths in a balanced position on both the left and right sides, and to prevent the plated objects from shifting in position and disrupting the parallel state. The purpose of the present invention is to provide a plated material transfer device with rollers that takes care to prevent the occurrence of damage.

Furthermore, the chuck and each roller are placed above the left and right sides of the roller device, and rotate to pick up and hold both the left and right sides of the plated object. By considering the positional relationship with the conventional chuck when receiving plated items,
To provide a device for transferring a plated article which can instantly receive the plated article above the left and right sides of rollers instead of holding and lifting the plated article, thereby shortening the time accordingly.

B) Structure of the Invention In order to achieve the above object, the present invention arranges a plurality of rollers above the entry side of the plating apparatus main body in order to transfer the plated objects to the plating apparatus main body, and transfers all the plated objects on the upper surface of each roller. A pair of left and right belts are provided with a plurality of positioning grooves on the outer peripheral surface of each roller, and are selectively engaged with these grooves and wound between a front roller and a rear roller. Make the top surface of the plating object the pass line,
Further, the chuck device is arranged to move forward and backward above the left and right sides of the roller device, and rotates there to pick up and hold both the left and right sides of the plated object.Only the plated object is positioned within the rotation locus of the chuck. The roller is configured to be positioned outside the rotation locus.

(e) Example Hereinafter, the present invention will be explained based on FIGS. 4 to 9 showing one example thereof. A plating device main body 20 is provided with a lawn device 21 and a chuck device 22 above the input side of the keel. The roller device 2H- has a pair of left and right frames 23, a shaft 25 supported by the frames 23 via bearings 24, and a plurality of rollers 26 mounted on the shaft 25, as shown in FIGS. A rear roller 27 to a front roller 28 form a roller group extending from the left side in FIG. 8 toward the plating apparatus main body 20. Each shaft 25 has either the left or right side (the left side in the example shown in FIG. 7) connected to the frame 23.
The pulley 29 protrudes outward, and a pulley 29 is mounted there, and each goo IJ
Each shaft 25Vi is rotatable via an endless belt 30 wound around 29 Vc. In addition to the pulley 29, another pulley 33 is attached to the shaft 32 supporting the second roller 31 from the inner surface of the front roller 28, and receives rotational force from a motor 34 via a timing belt 35. That's how it is. each shaft 2
A plurality of rollers 26 are mounted in the longitudinal direction of 5, that is, in the width direction (left and right direction in FIG. 6), depending on the number of parallel plated objects 36 to be transferred. is provided with a plurality of positioning grooves 38, and a pair of left and right belts 39 are attached by being selectively engaged with these grooves 38. A pair of left and right belts 39I''i are wound between the rear roller 27 and the front roller 28, on which the plated object 36 is placed and transferred from the entrance side [rear part] to the exit side [front part] of the roller device 21. This belt 39 forms a pass line 40.
Various cross-sectional shapes can be adopted, such as "0 type" and "V type," but the material of the plated item 36 is such that the plated item 36 placed on the left and right pair of belts 39 will not be misaligned. A material, such as rubber, that can exhibit an anti-slip function is used.

The interval between the pair of left and right belts 39 is set to be slightly smaller than the width of the plated object 36, and each time the type of plated object 36 to be processed changes, all of the plurality of positioning grooves 38 are selected according to the width. , the interval between the belts 39 is adjusted by engaging the belts 39 therewith.

As shown in FIG. 9, when the plated article 36 is placed on the pair of left and right belts 39, the top chuck device 22
The chuck device 2 is attached to the roller device 21 so that the chuck 42 is positioned within the rotation trajectory C of the chuck 42, and the outer circumferential surface 37 of each roller 26 is located outside the rotation trajectory C.
It is positioned correspondingly to the chuck 42 of No. 2.

A stopper 43 is arranged at the front end of the pass line 40, specifically near the front roller 28, and a sensor 44 is arranged near the stopper 43.
It is configured to automatically detect whether or not 6 has been placed and transferred, and to transmit a signal to the chuck device 22.

Next, the action will be explained. When a plurality of plated objects 36 are fed in parallel from the left side of FIG. 4, the roller device 21
The rear roller 27 takes over all of it and sends the plated material 36 to the front roller 28, and is stopped by a stopper 43.

A pair of left and right belts 39 are provided between the rear roller 27 and the front roller 28, and the rotational driving force is transmitted from the motor 34 to the timing belt 35, other pulleys 33, the shaft 32,
The information is transmitted to the pulley 29, the endless belt 30, and so on, and each roller 26 rotates in synchronization with the rotation of the shaft 25. Eventually, the plated material is fed and placed on a pair of left and right belts 39. The object 361-1 is transferred along the pass line 40 with its lower surfaces on both sides supported.

Then, the presence of the plated object 36 is confirmed by the sensor 44 while its advance is restricted by the stopper 43, and the chuck 42 of the chuck device 22 rotates in response to the signal. This chuck 42Vi is disposed above the left and right sides of the roller device 21 so as to be able to move forward and backward, and rotates to pick up and hold both the left and right sides of the plated object 36, and as shown in FIG. 9, the chuck 42 rotates. The side end (left end 41 in the example of FIG. 9) of the plated object 36 is located on the Nihabass line 40 within the moving path C. Since the outer circumferential surface 37 of each roller 26 is off from the rotation locus C, the chuck 42 can freely rotate without interference from the roller 26, specifically its outer circumferential surface 37, despite the presence of the roller 26. As a result, both left and right sides of the plated object 36 can be held and held.

Then, the chuck device 22Vi moves forward while holding the plating object 36 by a drive device (not shown), and the plating device main body 2
Chuck 42 that rotates in the opposite direction to the previous one on 0
The plating object 36 is transferred to the plating apparatus main body 20 with the plating device 6 in a free state.

When changing the type (shape, size, part to be plated, etc.) of the plated objects 36 placed and transferred by the roller device 21 depending on the line, the distance between the left and right pair of belts 39 is determined by selecting the positioning groove 38 to be engaged. This can be easily and quickly done without removing the roller 26 from the shaft 25 or without removing the roller 26 together with the shaft 25, for example, wide or narrow plated items 36a% 36b. It is also possible to reliably support and transport objects. Then, the plated objects 36, 36a, 36b can be placed and transferred at a position [pass line 40] separated from the outer circumferential surface 37 by the outer diameter size of the belt 39.

Even if the length of the plated object 36 changes, as shown in FIG. The plated objects 36c and 36d can be lifted and held on both left and right sides in a well-balanced position.

(f) As described in detail, in the plated material transfer device according to the present invention, the roller device has a plurality of positioning grooves on the outer peripheral surface of each roller, and the roller device is selectively engaged with these grooves. Moreover, the upper surfaces of the pair of left and right belts wound between the front roller and the rear roller serve as the pass line for the plated material, and are arranged so as to be able to move forward and backward above the left and right sides of the roller device, and rotate there to pass the plated material. Only the plated object is positioned within the rotational trajectory of the chuck of the chuck device that picks up and holds both the left and right sides of the material, and each roller is positioned outside of the rotational trajectory, resulting in many effects as listed below. Be expected.

(a) By adjusting the distance between the pair of left and right belts on the rollers to match the entire positioning groove, plated objects of different widths can be reliably supported and transferred to a predetermined position; (b) During this time, the plated items are supported by the upper surfaces of the pair of belts on the left and right sides of the bottom side of the plated items, so that the plated items are not misaligned and can be prevented from becoming disordered in their rows. Objects are supported by a pair of left and right belts 1c6 at a position above the outer peripheral surface of the roller by the outer diameter of the belt, so that the chuck of the chuck device, which can move forward and backward on both the left and right sides, can rotate smoothly. (d) Roller When receiving a plated object from the device, as mentioned above, the plated object can be placed on the chuck at a position above the outer peripheral surface of the roller, so even when plated objects of different lengths and short sizes are received, the plated objects can be placed on both the left and right sides of the roller device. The position of the chuck of the chuck device, which is arranged above the machine so that it can move forward and backward, can be simply adjusted relative to the length and length of the plated object, and there is no need to adjust the distance between the rollers as in the past.
(θ) The synergistic effect of the above (a) to (a) also has the additional effect of increasing the speed of the plating process.
