(Problems to be Solved by the Invention) In the above-mentioned conventional apparatus, since the manual work is mainly performed, it is difficult to control the heating temperature, the heating time, the pressure contact force and the like.

As a result, insufficient adhesion, insufficient adhesion due to excessive heating, or insufficient adhesion due to insufficient pressure contact force,
There is a problem in that crimping may be defective, and a great deal of effort is required to ensure uniform quality.

The present invention has been made in view of the above-mentioned points, and the purpose thereof is that heating and press-contacting operations are always performed in a predetermined manner to obtain stable adhesion of quality, and these operations are labor-saving. It is to be carried out.

(Means for Solving the Problems) The constitution of the present invention for solving the problems of the above-mentioned conventional device includes a pressurizing device, a heating device provided below a press head of the pressurizing device, and a pressurizing device. The table that travels between the operating position of the device and the preparation position where the work is attached to and detached from the table, the operation of the position switch that detects when the table reaches the preparation position, and the heating device is set at a temperature higher than the set temperature. A thermocompression bonding machine having a control device that outputs a control command to a pressurizing device so that a predetermined press operation is started based on the operation of a thermosensor that detects a certain condition.

(Operation) When the work is attached to the table at the preparation position and the table is moved, when the operating position is reached, the press head presses the two pressure-bonded portions together according to the command from the control device, and the heating device heats them. The crimping of the crimped portion is completed.

In this way, each operation of pressurization and heating is automatically performed, so stable pressure bonding can be obtained, and the work is saved.

When the heating device does not reach the set temperature due to, for example, a break in the heater, the press operation is stopped by a command from the control device, so it is immediately known that the heater is defective, and there is also the risk of consecutive defective crimping. It was resolved.

Since the work is attached and detached at a preparatory position that is out of the operating position of the press head, an accident such as a worker being caught in the hand does not occur.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a front view of the thermocompression bonding machine, and FIG. 2 shows a side view thereof.

In the thermocompression bonding machine, four guide posts 2 are erected on a base plate 1, an upper base plate 3 is attached on top of these guide posts 2, and a cylinder 4 as a pressure device P is attached to the upper base plate 3. Installed.

A carriage plate 5 is vertically movably fitted to two guide posts 2 and 2 shown on the left side of FIG. 2 (reference numeral 6 denotes a bearing thereof), and a lower end portion 7c of a piston 7 of a pressure device P is provided.
Attaches the carriage plate 5 with bolts 8 so as to be removable.

The heating device H is attached to the lower end portion of the carriage plate 5 via the attachment plate 9 and the heat insulating plate 10.

As shown in the exploded perspective view of FIG. 3, the illustrated heating device H includes a lower heater block 1 having a thin bottom plate 11a.
The disk-shaped heater 12 is fitted into the hole 11b of No. 1 and the boss 13 of the upper heater block 13 fitted into this hole 11b.
The heater 12 is attached to the lower heater block 11 and the upper heater block 13 by a, and the lower heater block 11 and the upper heater block 1 are provided.
3 also functions as a press head.

The base plate 1 has a front view. Shaped guides 14 and 14 are fixed, and a table T is provided so as to be slidable along the guides 14 and 14 in a direction perpendicular to the paper surface of FIG. 1 (left and right direction in FIG. 2).

The illustrated table T includes the guides 14 and 14 and the left and right portions 15
slide base 15 in which a and 15a are fitted, and a flat grip plate 16 attached to the slide base 15
And a holder plate 17 mounted on the grip plate 16.

Behind both left and right ends of the base plate 1, the back side stopper 1
8 and the front side stopper 19 are attached respectively, and the slide base 15 contacts the back side stopper 18 (solid line in FIG. 2).
In the state where the holder plate 17 is provided below the heating device H and is in the operation position where pressurization and heating are possible, and the slide base 15 contacts the front side stopper 19 (two-dot chain line in FIG. 2), The plate 17 is in a preparation position where the work W can be safely attached and detached from the heating device H.

When the table T arrives at the operating position from the preparation position, the husband and wife issue a command to perform a predetermined pressing operation by the heating device P and a predetermined heating operation by the heating device H, and when the heater 12 is disconnected. For this reason, when the lower heater block 11 and the upper heater block 13 do not reach the predetermined temperature, the control device C that outputs a command to stop the press operation is provided.

The sensor used in the illustrated control device C is a microswitch SW that detects the both ends of the movement of the slide base 15,
Thermo sensors St ₁ , St ₂ , which detect the temperature of the heater 12,
The pressing position of the pressure device P and the proximity switch Sa for detecting the uppermost position are mainly used.

That is, when the slide base 15 hits the backside stopper 18, a valve (not shown) opens, so that pressurized air is supplied to the upper surface side of the piston 7, and the piston 7 begins to descend together with the carriage plate 5.

The proximity switch Sa operates at a position where the lower heater block 11 is pressed against the work W on the holder plate 17 (the magnet a ₁ attached to the piston 7 approaches the switch portion a ₂ attached to the cylinder 4). 7, the timer TM starts counting at the same time,
After the predetermined number of counts, the pressure air is supplied to the lower surface of the piston 7, and the pressing and heating are finished, and the upper heater block 13 has two salmon sensors St ₁ , St.
₂ is attached. Therefore, the thermo sensor St ₁
Is used for controlling the temperature of the heater 12, and the other thermosensor St ₂ detects a low temperature when the heater 12 cannot perform normal heating, for example, a low temperature when the wire is broken, and thereby stops the pressing operation of the pressurizing device P. As described above, the command from the control device C is issued.

Switch S on the microphone for position detection of slide base 15
In order to prevent damage accidents, W is designed so that the slide base 15 pushes the operator SWa of the microswitch SW via the slide pin 20 loosely inserted into the backside stopper 18, as shown in FIG. When the slide base 15 is returned to the front side, the slide pin 20 is returned to the original position by the return spring force of the operator SWa as shown in FIG.

Next, the operation of the thermocompression bonding machine will be described.

(1) One work piece W ₁ of the work W is positioned by the guide pin 22 provided on the holder plate 17, and the other work piece W ₂ is placed on the work piece W ₁ .

(2) When the gripping ball 23 attached to the grip plate 16 is gripped, the table T is moved from the preparation position toward the operating position and abutted against the back side stopper 18, the micro switch SW operates.

(3) Control device C by the operation of the micro switch SW
Lowers the piston 7.

(4) When the work pieces W ₁ and W ₂ are pressed against each other by the lower heater block 11 and the holder plate 17, the heater 1
The heating operation by 2 is also performed, and the proximity switch S
a operates and the timer TM starts counting.

(5) When the predetermined count is completed, pressure air is supplied to the lower surface of the piston 7 according to a command from the control device C, and the heating device H moves up together with the piston 7.

(6) When the table T is pulled out to the front side, returned to the preparation position, and the work piece W that has been crimped is removed from the holder plate 17, the work is completed.

As described above, since the work W is attached to and detached from the table T at the preparation position separated from the lower side of the pressurizing device P, the work is a safe operation.

(Effects of the Invention) The thermocompression bonding machine according to the present invention is configured as described above, and when the work is attached to the table at the preparation position and the table is moved, when the operating position is reached, the control device issues a command. Based on this, the press head presses both pressure-bonded parts of the work,
Heating is performed by the heating device, and the crimping of the crimping portion is completed.

In this way, since each operation of pressurization and heating is automatically performed, it is possible to perform crimping with stable quality, and the work is saved.

When the heating device does not reach the set temperature due to, for example, a break in the heater of the heating device, the pressing operation is stopped by a command from the control device. In addition to being useful, it also eliminated travel, which is the continuation of defective crimping products due to pressure contact with poor heating.

When mounting or dismounting the work on the table, it is done at the preparation position which is out of the operating position of the press head.
Accidents such as an operator accidentally pinching his / her hand with the press head will not occur.

Due to the above effects, quality is stable, work efficiency is good,
Moreover, the thermocompression bonding machine has various excellent functions such as safe work.
