Description

[Detailed Description of the Invention] The present invention relates to a film carrier conveying device.

Film carriers used for bonding IC and LSI chips have recently been improved in material and are now being used more frequently. However, since the carrier is a non-metallic synthetic resin film, it is difficult to use a sprocket method, so pitch rollers are used instead. Often required.

The present invention is an improvement on the latter conveyance means, and aims to provide a film carrier conveyance device in which the feed pitch for conveyance can be arbitrarily adjusted. A plurality of cam plates that can freely adjust the difference in rotation angle are mounted on the drive rotation shaft of the pinch roller that rotates while pinching the film carrier and conveys the film carrier, and each is equipped with a limit switch that is controlled by each cam plate. However, it is an object of the present invention to provide a film carrier conveyance device characterized in that the feed pitch of the film carrier is made variable by control signals from these limit switches.

Below, the details will be explained based on the drawings. 1a, lb
The lower guide roller 1a is provided with flanges 2 on both sides, and the film carrier 3 is guided between the flanges 2, 2.

Pinch rollers 4 a and 4 b are arranged on the exit side, facing the guide rollers la and lb on the entry side.

Guide rollers la, lb and pinch rollers 4a, 4
A device for processing the film carrier 3, for example, a spray-type partial plating device 5 for gold plating is positioned between the portions b.

Since this injection type partial plating device 5 uses a known device, the details will be omitted, but there is a plating device main body 6 equipped with an injection nozzle, a mask body, etc. on the lower side, and a pressing plate 7 on the upper side for the mask body. A pressure cylinder 8 is provided in each case.

By the way, in the aforementioned pinch rollers 4a and 4b, which constitute the main part of the present invention, the lower pinch roller 4a can be pressed upwardly by a pressure cylinder 9, and the upper pinch roller 4b can be pressed upwardly by a pressure cylinder 9. The position is fixed and it is rotatable around a rotary drive shaft 10.

Of course, the pinch rollers 4 a and 4 b are not limited to the illustrated example, and the lower roller may be a driving rotation roller, and the upper roller may be a pressing movable roller.

The rotation drive shaft 10 is supported by a bearing 11 and connected to a motor 12 which is a rotation drive source.

The connection to the motor 12 may be a direct connection or a clutch (not shown) may be interposed, and in the illustrated example, a sleeve joint 13 is used.

A plurality of cam plates, two cam plates 14 a and 14 b in the illustrated example, are mounted on this rotary drive shaft 10 via mounting discs 15 .

Both cam plates 14a and 14b are each fixedly fixed to the mounting table 15 via screws or other fastening means.
Elongated holes 16 for this purpose are formed in both cam plates 14a and 14b, and the rotation angle, that is, the positioning in the circumferential direction with respect to the mounting disk 15, is determined within the range of the circular arc distance l of the elongated holes 16. can be freely adjusted.

Limit switches 17 a and 17 b are attached to both cam plates 14 a and 14 b, respectively, and the limit switches 17 a and 17 b are always in contact with the cam surfaces 18 a and 18 b and are formed on the cam surfaces 18 a and 18 b. It is controlled by the recesses 19a and 19b.

Nomit switches 17a and 17b are connected to a control panel (not shown), and this control panel also connects the motor 1
2. Connected to pressure cylinder 9 and spray type partial plating device 5.

Since this control panel is a known one that incorporates relays, timers, switches, etc. into a panel box, illustration and detailed description thereof will be omitted.

Further, the recess 19a of the cam plate 14a is the film carrier 3.
The recess 19b of the cam plate 14b sends a start signal for the conveyance cycle, and a stop signal for stopping the conveyance is sent to the control panel via limit switches 17a and 17b, respectively, and the latter conveyance stop signal means a start signal of a plating cycle linked to the injection type partial plating device 5, and upon receiving these start signals or conveyance stop signals (start signal of a plating cycle), the control panel further controls necessary equipment, such as the motor 12, pressure cylinder
9, signals are sent to the injection type partial plating device 5, respectively.

Further, both the recesses 19a and 19b are fixedly fixed to the mounting table 15 with shifted positions, and there is a difference in rotation angle by α.

Next, the action will be explained.

First, the lower pinch roller 4a is pressed against the other pinch roller 4b by the pressure cylinder 9, and the film carrier 3 is held between both rollers.

At this time, the rotation of the rotational drive shaft 10 in the clockwise direction in FIG. 1 (idle feeding) causes the cam plate 14a to
14b similarly rotates clockwise in FIG. 3, and the cam plate 14
When the limit switch 17a detects the recess 19a (FIG. 3A), a start signal is sent to the control panel (not shown), which instructs the pressure cylinder 9 and motor 12 to start the conveyance cycle. and the transport cycle starts.

Then, the lower pinch roller 4a is connected to the other pinch roller 4.
The film carrier 3 is pinched by being pressed by the pinch rollers 4a and 4b, and the motor 12 rotates the rotary drive shaft 10, and the film carrier 3 is conveyed by the pinch rollers 4a and 4b.

(Note that when the limit switch 17a detects the recess 19a, the other limit switches 17b are in a non-sensing state with respect to the recess 19b, as shown in FIG. 3B.

) Next, when the mounting disk 15 rotates due to the same clockwise rotation of the rotary drive shaft 10, the limit switch 17b detects the recess 19b of the cam plate 14b according to the rotation angle α. Figure C) Sends a stop signal to the control panel and motor 12 stops.

This stop signal is treated as a start signal for the plating cycle, and the control panel issues an instruction for the plating cycle. In other words, the pressure cylinder 8 lowers the pressing plate 7 and connects it to a mask body (not shown) in the plating apparatus main body 6. The film carrier 3 is held in between and the spray plating process is performed.

On the other hand, following the lowering of the pressure cylinder 8, the pressure cylinder
9 also descends, and the pinch rollers 4 a and 4 b release their grip on the film carrier 3 .

Then, the motor 12 operates again according to instructions from the control panel, causing both cam plates 14a and 14b to rotate, and when they rotate by L minutes (C in Figure 3), the cam plate 1 returns to its starting state.
4a is restored to a state in which the recess 19a engages with the limit switch 17a.

The idle feeding of the cam plates 14a and 14b for L is completed, the plating cycle is completed during this empty feeding, and the pressure cylinder 8 is raised to a state where the film carrier 3 can be conveyed again. When the plating cycle is completed, the transport cycle is started again when the plating cycle is completed.

In the above series of conveyance operations, the film carrier 3
The feed pitch is determined by the cam plate 14 installed on the rotary drive shaft 10.
Recesses a, 14 b, i.e. recess 1 regulating the start
9a and a recess 19b that regulates stopping are each cam surface 18.
It is determined by the rotation angle difference α between the circular arcs a and 18 b.

(Fig. 3C) Therefore, if the above-mentioned rotational angle difference by α is changed, the feed pitch will also change accordingly.

In the above explanation, the object to be conveyed is specified as a film carrier, but it is not limited to this, and may be a tape-shaped object,
It is fully applicable to any coiled band-shaped product.

Since the film carrier conveying device according to the present invention has the contents as described above, the rotation angle of the pinch roller, in other words, the rotation angle of the pinch roller, is controlled by the combination of a plurality of cams and a limit switch controlled by each cam. The feed pitch for conveyance can be set freely, and the mounting position of each cam plate relative to the mounting disk (i.e. rotation angle difference) can be set freely.
Since the feed pitch can be finely adjusted very easily by changing , it is very easy to handle and has great benefits.
