Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface mounting method and a mounting machine, and more particularly to a surface mounting method and a mounting machine suitable for simultaneously connecting a large number of terminals as represented by a liquid crystal driver mounting. .

[0002]

2. Description of the Related Art In a production line of a liquid crystal display used for a display screen of a mobile phone or a notebook computer,
A process for mounting a liquid crystal driver as a work on a liquid crystal glass substrate for displaying an image is provided.

In the mounting process of the liquid crystal driver, first, the glass substrate for the liquid crystal is set on the gantry, and then the alignment of the liquid crystal driver is performed so that the lead terminals of the liquid crystal driver are overlapped with the terminals provided on the liquid crystal glass substrate. I do. After the alignment of the liquid crystal driver with respect to the liquid crystal glass substrate is completed, the high-temperature heat tool is lowered from above the liquid crystal driver, and the tip of the heat tool (tool tip) is moved to the position of the liquid crystal driver. By pressing the lead terminals against the terminals of the glass substrate for liquid crystal, the lead terminals are connected to the terminals of the driver for liquid crystal.

[0004] A mounting machine used for mounting a liquid crystal driver on a liquid crystal glass substrate includes the above-described heat tool and elevating means for elevating the heat tool. A heater is mounted inside the heat tool, and by operating the heater, the heat tool can be set to a predetermined temperature. On the other hand, in the elevating means, a pneumatic cylinder connected to the heat tool is provided,
By operating this pneumatic cylinder, the heat tool is raised and lowered.

In such a mounting machine, when the heat tool heated by the heater approaches the liquid crystal driver, radiant heat from the heat tool heats the liquid crystal driver and other peripheral members, resulting in failure and dimensional fluctuation. May occur. When such a failure is expected, cooling air is blown to a region other than the lead terminals pressed by the tool tip to prevent the ambient temperature from rising due to radiant heat from the heat tool.

[0006]

However, the above-described method of blowing the cooling air toward the work has the following problems. In other words, the surface mounting is generally performed in a clean room. However, if air is constantly blown out in the clean room, dust may fly up into the air one after another, accumulate on the surface of a product or the like, and cause a problem. was there.

In the above-mentioned cooling, since the cooling air is constantly blown regardless of the elevation of the heat tool, there is a problem that the pneumatic energy by the compressed air is wasted. In particular, compressed air used in a clean room is expensive, with items such as temperature, humidity and cleanliness controlled, and wasteful use of such compressed air is a factor that reduces energy efficiency in the manufacturing process. Also.

The present invention is directed to a surface mounting method and a mounting machine capable of minimizing dust and the like caused by air blowing and reducing the amount of compressed air, focusing on the above conventional problems.

[0009]

According to the present invention, if a heat shielding plate is provided so as to surround a tool tip of a heat tool instead of air blow, radiant heat from the heat tool is prevented from reaching the work side. It has been made based on the finding that it can be done.

In other words, the surface mounting method according to the present invention is a surface mounting method for mounting the work by performing heat pressing on the work by lowering the heat tool, and surrounding the tip of the tool pressing the work. With a heat shield,
The radiant heat of the heat tool reaching the work is configured to be blocked. Preferably, a cooling medium is fed into the heat shield plate.

When the surface mounting is performed in such a procedure, radiant heat is emitted from the surface of the heated heat tool, but the heat tool is surrounded around the tip of the tool which presses the work. As described above, since the heat shield plate is provided, the shield plate can receive the radiant heat and can prevent the radiant heat from reaching the work side. Then, if a cooling medium is fed into the heat shield plate, the cooling efficiency of the heat shield plate can be improved. By providing the heat shielding plate around the heat tool in this way, even if a cooling medium is used, the cooling medium does not scatter around, thus preventing an obstacle such as dust flying up. be able to. It is desirable to use air as the cooling medium.

Further, a second surface mounting method according to the present invention comprises:
A surface mounting method for performing heat-press bonding to a work by lowering a heat tool to perform mounting of the work, wherein when the heat tool is pressed against the work, a heat shielding plate surrounds a tool tip, and the work is attached to the work. The heat tool is configured to block the radiant heat of the heat tool.

When the heat shield surrounds the tip of the tool, it is preferable to supply a cooling medium into the heat shield. If the surface mounting is performed in such a procedure, when the heated heat tool descends to the work side, the heat shielding plate begins to surround the tool tip as the heat tool descends, and the tool tip presses the work side. In some cases,
A heat shield completely surrounds the tool tip. By surrounding the tool tip with the heat shielding plate in this way, radiant heat from the heat tool is blocked, and the radiant heat can be prevented from reaching the work side. For this reason, it is possible to prevent a problem such as a failure or a dimensional change due to heating from occurring on the work side. Further, the heat shield plate surrounds the heat tool only when the tool tip presses the work, and when the heat tool rises, the two are separated from each other. For this reason, in a state other than the state where the tool tip presses the work, the radiant heat from the heat tool is not absorbed by the heat shield plate.
The load on the heating element incorporated in the heat tool can be reduced, the temperature of the heat tool can be kept constant, and the amount of power energy used can be reduced. In addition, since the heat shielding plate is used in place of the conventional continuous blowing of air, it goes without saying that the amount of compressed air used can be reduced and dust can be prevented from scattering.

When the cooling medium is fed into the heat shield plate when the tool tip presses the work side, the cooling efficiency of the heat shield plate can be further improved. It is desirable to use air as the cooling medium.

When the heat shielding plate surrounds the tip of the tool, if cooling air is blown to the work, heat damage applied to the work can be further reduced. Since the supply of the cooling air is performed only when the heat tool is lowered, the cooling air can be effectively used.

Further, a mounting machine according to the present invention has a heat tool, and elevating means connected to the heat tool,
A mounting machine for mounting the work by heating and pressing the tip of the tool to the work, wherein a heat shielding plate is provided so as to surround the tip of the tool, so that radiant heat of the heat tool reaching the work is blocked. Preferably, a cooling medium passage is formed in the heat shield plate, and a cooling medium supply unit is connected to the cooling medium passage to supply the cooling medium to the cooling medium passage. .

If such a mounting machine is used,
As described above, a heat shield plate is provided around the heat tool so as to surround the tip of the tool that presses the work. For this reason, even if radiant heat is emitted from the heated surface of the heat tool, the heat shield plate receives the radiant heat, so that the radiant heat can be prevented from reaching the work side.

Further, if a cooling medium passage is formed inside the heat shield plate and the cooling medium is fed to the cooling medium passage, heat exchange is performed by the cooling medium, and Cooling efficiency can be improved. By providing a heat shield around the heat tool in this way,
Even if the cooling medium is used, the cooling medium does not scatter around, and it is possible to prevent an obstacle such as dust flying near the apparatus.

The second mounting machine according to the present invention has a heat tool and elevating means connected to the heat tool, and mounts the work by heating and pressing the tip of the tool to the work. A reciprocating means provided on the side of the heat tool, and a heat shield plate capable of surrounding the tool tip is attached to the reciprocating means, and the reciprocating means is provided with the heat tool. When the work is pressed, the reciprocating means is advanced to connect a control means for surrounding the tip of the tool with the heat shielding plate, and the heat shielding plate is preferably a heat insulating member.

A cooling medium passage is formed in the heat shielding plate, and a cooling medium supply means connected to the control means is connected to the cooling medium passage. At the time of surrounding the distal end portion, a cooling medium may be supplied to the cooling medium passage, and the cooling medium is preferably air.

An air injection means connected to the control means is mounted on the heat shield plate, and when the heat shield plate surrounds the tip of the tool, cooling air is blown to the work. Is also good. When such a mounting machine is used, when the heated heat tool is to be lowered to the work side, the control means detects the lowering of the heat tool, and the control means operates the reciprocating means. The reciprocating means installed on the side of the heat tool advances the heat shield when receiving a signal from the control means, and when the tool tip presses the work side, the heat shield is moved to the tool tip. Completely surround the part. By surrounding the tool tip with a heat shield in this way,
Radiation heat from the heat tool is blocked, and the radiation heat can be prevented from reaching the work side. For this reason, it is possible to prevent a problem such as a failure or dimensional change due to heating from occurring on the work side.

After completion of the heat press bonding of the work at the tool tip, the heat tool may be raised to separate the tool tip from the work. When the control means detects the rise of the heat tool, the control means operates the reciprocating means to move the heat shield plate backward from the tip of the tool. When the heat tool is raised in this way, the heat shield plate separates in accordance with the rise of the heat tool, so that the heat shield plate does not absorb radiant heat from the heat tool. Therefore, it is possible to reduce the load of the heating element built in the heat tool, to keep the temperature of the heat tool constant, and to reduce the amount of power energy used. In addition, since the heat shielding plate is used in place of the conventional continuous blowing of air, it goes without saying that the amount of compressed air used can be reduced and dust can be prevented from scattering.

When the cooling medium is fed to the cooling medium passage formed in the heat shield plate when the tool tip presses the work side, the cooling medium is fed to the cooling medium passage. The heat exchange is performed in the cooling medium, and the cooling efficiency of the heat shield plate can be further improved.

When the heat shielding plate surrounds the tip of the tool, if cooling air is blown to the work, heat damage applied to the work can be further reduced. Note that the supply of the cooling air is performed only when the heat tool is lowered and cooling is most necessary, so that the amount of the cooling air used can be minimized.

That is, in the main body 32, a ventilation path 38 serving as a cooling medium passage is formed along the longitudinal direction, and a cooling surface is formed on the front surface 40 of the main body 32 so as to reach the ventilation path 38. An air inlet 42 and a cooling air outlet 44 are formed, and the heat shield plate 30 is cooled by sending cooling air serving as a cooling medium to the ventilation path 38 through these holes. Like that. By the way, in the present embodiment, air is used as the cooling medium. However, the present invention is not limited to this. For example, nitrogen or the like may be used for the purpose of preventing oxidation, or another cooling medium may be used. You may.

On the other hand, the tongue piece 36 projecting from the bottom surface of the main body 32 has a total width of at least the tool tip 22.
When the pair of heat shield plates 30 is advanced to the heater block 16 side, the tongue pieces 36

It suffices if the heat shield plate 30 has only a function surrounding the heater block 2. Therefore, the left and right heat shield plates 30 do not need to have the same shape, and may have different shapes according to the outer shape of the heater block 16.

In such a heat shield plate 30, an air supply means (not shown) is connected to the cooling air introduction port 42, and the cooling air is supplied to the ventilation path 38 by operating the air supply means. Like that. The cooling air that has passed through the ventilation path 38 is

The air cylinder 26 and the air supply means can be operated.

A procedure for performing heat compression bonding to a workpiece using the mounting machine 10 having the above-described configuration will be described. FIG. 4 is a flowchart showing the operation procedure of the mounting machine. As shown in the figure, when performing heat press bonding to a work, first, the power supply of the apparatus is turned on, and the heater mounted inside the heater block 16 is operated (step 100). Then, the work is set on the stage 21 below the tool tip 22 (step 110), and thereafter, it is confirmed whether the temperature of the heater block 16 has reached an arbitrary value by a temperature sensor mounted on the heater block 16 (step 110). Step 120).

After it is confirmed by the temperature sensor that the temperature of the heater block 16 has reached an arbitrary value, the heat tool 12 is lowered by the elevating air cylinder 14, and the high-temperature tool tip 22 is moved to the work. Press (step 130).

When the elevating air cylinder 14 operates and the heat tool 12 starts to descend, the control means 52 receives a descending signal of the elevating air cylinder 14 in conjunction with this operation, and Advance and operation of the air supply means are performed (step 140). When the operations of steps 130 and 140 are completed, the state is maintained for a certain period of time (step 150). At this time, the work is heated and pressed from the tool tip 22 to the work. A heat shield plate 30 is inserted between the work and the work to absorb the radiant heat from the heater block 16 and exchange heat with the cooling air passing through the ventilation path 38. The radiant heat from the heater block 16 is prevented from reaching the location. For this reason, it is possible to prevent a heat shock due to radiant heat from being applied to the work itself or members located around the work.

After the tool tip 22 heats and compresses the work for a predetermined time, the elevating air cylinder 14 is operated again to raise the heat tool 12 (step 1).
60). Then, in conjunction with the raising operation of the heat tool 12, the control means 52 receives the raising signal of the lifting air cylinder 14, stops the reciprocating cylinder 26 and stops the air supply means (step 170).

As described above, the heat shield plate 30 is moved in and out according to the elevation of the heat tool 12, so that
When the tool tip 22 is heating and pressing the work,
Since the heat shield plate 30 absorbs the radiant heat from the heater block 16, it is possible to prevent the radiant heat from reaching the periphery of the work. In other states, the heat shield plate 30 separates from the heater block 16. The amount of heat radiation of the block 12 is reduced, and the load on the heater can be reduced.

Further, in the same manner as when the heat shield plate 30 is taken in and out, cooling air is supplied to and stopped from the ventilation path 38 in accordance with the elevation of the heat tool 12, so that the tool tip 22 heats the work. During pressure bonding, radiation heat from the heater block 16 can be efficiently absorbed. In other states, the heater block 16 is separated from the work, and there is no need to cool the heat shield plate 30, so that the supply of cooling air is stopped, and the amount of compressed air used can be reduced. The cooling air is
Since the air only passes through the inside of the heat shield plate 30, the air near the work does not wind up, so that it is possible to prevent troubles such as accumulation of dust on the surface of the work.

In this embodiment, the heat shielding plate 30
A ventilation path 38 is provided inside the inside, and cooling air is supplied to the ventilation path 38 to block radiant heat from the heater block 16. However, the present invention is not limited to this mode, and other methods may be used. It may be used to block radiant heat.

FIG. 5 is a structural explanatory view showing an application example of the mounting machine according to the present embodiment. In this application example, the same members as those of the mounting machine 10 are given the same numbers. In the mounting machine 54 as shown in the figure, a heat insulating material such as ceramics is used for the heat shield plate 56. When the heat insulating material is used for the heat shielding plate 56 in this manner, the heat shielding plate 56 is inserted between the heater block 16 and the stage 21, so that the radiant heat from the heater block 16 is blocked, and the radiant heat is It can be prevented from reaching the side.

If a heat insulating material is used for the heat shielding plate 56 in this way, in addition to the function and effect of the mounting machine 10, there is no need to supply cooling air for cooling the heat shielding plate 56, and the compression The amount of air used can be reduced.

Although the radiant heat from the heater block 16 is blocked by the above-described heat shield plate 30 and the heat shield plate 56, in order to further reduce the temperature of the area other than the heat-compression-bonded portion of the work, the heat What is necessary is just to blow cooling air to the area | region other than a crimp part, and to cool it positively. When the cooling air is blown in this way, it is necessary to provide air injection means on the heat shield plate. At this time, if the air injection means is also connected to the control means 52, the tool tip 22 heats the work. Cooling air can be blown only during crimping (in the figure,
Thus, efficient cooling can be performed without wasting compressed air.

FIG. 6 is an explanatory view showing the structure of the heat tool in the second embodiment. Note that, in the same embodiment,
The same members as those of the mounting machine 20 described above are given the same part numbers. As shown in these figures, in the second embodiment, the heat shield plate 60 is fixed to the heat tool 12 side by using a mounting bracket 62, and the heat tool 12
At the same time, the heat shield plate 60 is moved up and down. Note that a cooling medium passage path is formed inside the heat shielding plate 60 so that cooling air is supplied as indicated by an arrow 64.

When the heat shield plate 60 is fixed to the heat tool 12 side and the heat shield plate 60 is raised and lowered together with the heat tool 12, the radiant heat emitted from the area excluding the tool tip portion 22 is reduced. It is absorbed by the plate 60. For this reason, it is possible to suppress the radiant heat from reaching the work side, and prevent the work side from being damaged by heat shock. The cooling air is supplied by the heat shielding plate 6.
Since the air only passes through the inside of the workpiece 0, the air near the workpiece does not wind up, and it is needless to say that obstacles such as accumulation of dust on the surface of the workpiece can be prevented.
