Description

  The present invention relates to a bonding apparatus, and more particularly to an invention capable of attaching circuit integrated elements to liquid crystal display panels of various sizes without replacing the bonding apparatus.

  The bonding apparatus is an apparatus that attaches a circuit integrated element to a circuit line of a liquid crystal display panel using high temperature and high pressure. Conventionally, in Patent Document 1, for example, a long bar type heating member and a pressure bonding part are used as a backup member. In a state where the integrated circuit elements are mounted on the liquid crystal display panel mounted on the substrate, they are bonded by pressing them at high temperature and pressure.

  In general, a liquid crystal display device using a liquid crystal display panel is composed of two panels on which electric field generating electrodes are formed and a liquid crystal layer inserted between them, and a voltage is applied to the electrodes to By rearranging the liquid crystal molecules, the transmittance of light passing through the liquid crystal layer is adjusted.

  Such a liquid crystal display device includes a liquid crystal display panel in which pixels are arranged and an image display region is formed, and a drive circuit that inputs a drive signal to the liquid crystal display panel, and a circuit pattern provided around the liquid crystal display panel. A drive signal is input from the drive circuit to the liquid crystal display panel via the.

  Around the liquid crystal display panel, a plurality of integrated circuit elements (ICs) that generate an output signal by controlling an input signal at a certain timing are arranged.

  In the process of mounting such an integrated circuit element (IC) on a liquid crystal display panel, first, an ACF (anisotropic conductive film) is attached to a circuit pattern provided on the peripheral portion of the liquid crystal display panel. The ACF is heated using a preheating head.

  After that, the output-side terminal of the integrated circuit element and the circuit pattern of the liquid crystal display panel are aligned, and then temporary crimping is performed, and final crimping is performed using the long bar type bonding apparatus.

  Then, the input side terminal of the integrated circuit element and the terminal group on the PCB for driving input are connected by thermocompression bonding via the ACF using a thermocompression bonding tool. This completes the process of mounting the integrated circuit element (IC) on the liquid crystal display panel.

  However, in the prior art, it is necessary to press and heat the liquid crystal display panel and the integrated circuit element using a long bar-type crimping portion corresponding to the width of the liquid crystal display panel. At this time, the flatness of the crimping portion is Since the adhesive property between the liquid crystal display panel and the integrated circuit element is greatly affected, there is an inconvenience that the flatness of the crimping member must be periodically checked and managed.

  In addition, there is a problem that the longer the length of the long bar-type crimping part, the more difficult it is to process the crimping part.

  Note that the flatness of the table-shaped resting part provided on the lower part of the crimping part and resting the liquid crystal panel and the crimping part also greatly affects the adhesion characteristics between the liquid crystal display panel and the integrated circuit element. The flatness is adjusted with reference to the flatness of the crimping part, and when the entire long bar type crimping part is replaced, the flatness of the upper part of the erection part must be adjusted again.

  In addition, when the crimping part for attaching the integrated circuit element to the liquid crystal display panel of a specific size is used for a liquid crystal display panel of another size, the bonding device used for the large liquid crystal display panel is particularly small. When used in a liquid crystal display panel, there is a problem that the flatness of the crimping part becomes non-uniform due to the difference in thermal deformation between the part that is in contact with the integrated circuit element and thermocompression bonding and the part that is not. For this reason, there is a problem in that a specific-sized panel has to be used with a specific-length crimping part.

Moreover, when some of the plurality of integrated circuit elements are made of a material different from that of the other integrated circuit elements, the crimping conditions and the heating conditions must be appropriately changed according to the material. Since the liquid crystal display panel and the integrated circuit element are adhered to each other at the same temperature and the same pressure, there is a problem that only one type of integrated circuit element can be used when a long bar type crimping part is used. It was.

It is done.

  The vertical movement unit 3 can be horizontally moved left and right by a horizontal movement unit 4 provided on the frame 1, and the bonding unit 10 is horizontally moved by such horizontal movement of the vertical movement unit 3. The interval between 10 can be adjusted.

  The horizontal moving unit 4 includes a drive motor 6 provided on one side of the frame 1, a pulley 7 provided on the upper and lower sides of both sides of the frame 1, and an upper side and a lower side of the frame 1, respectively. A connecting belt 9 that connects the provided pulley 7 and a guide rail 5 that is coupled to the vertical movement unit 3 and guides the horizontal movement of the vertical movement unit 3 in a sliding manner.

  Here, the drive motor 6 is connected to a pulley 7 provided at one side lower part of the frame 1, and the pulleys 7 provided at both upper parts of the frame 1 are connected to each other via a connecting shaft 8. In this case, the pulley 7 directly connected to the drive motor 6 is a main pulley, and the other pulleys 7 are driven pulleys.

  A cam plate 2 is connected to the connecting belt 9 by a fixing member 2b, and a moving slit 2a into which a protruding portion 3a protruding forward from the front surface of the vertical moving portion 3 is formed inside the cam plate 2. ing.

  Here, the protruding portion 3 a is not limited to the vertically moving portion 3 and may be installed in the bonding portion 10.

  On the other hand, the moving slits 2a are provided by the number of the bonding parts 10 and the vertical moving parts 3, and are provided at regular intervals, and the mutual intervals are gradually narrowed from the lower part to the upper part.

  As described above, the moving slit 2a is arranged radially downward with the front central portion of the cam plate 2 as the center, so that the vertical movement of the cam plate 2 is the vertical moving portion 3 and the bonding portion connected thereto.

  Such vertical movement of the connecting belt 9 leads to vertical movement of the cam plate 2, and then the vertical movement of the cam plate 2 is switched to the horizontal movement of the vertical movement unit 3 and the bonding unit 10.

  On the other hand, an ACF 72 attached to the upper surface of the liquid crystal display panel 70 and an integrated circuit element 74 temporarily bonded to the ACF 72 are provided on the upper surface of the erection unit 50. Is done. Here, a method of attaching the integrated circuit element 74 is based on a COG (Chip On Glass) method in which an integrated circuit element (not shown) is directly mounted, or by a TCP (Tape Carrier Package) or COF (Chip On Film). . In particular, recently, TCP and COF are often used, and details of TCP and COF will be described later.

  With reference to FIG. 2, the structure of the bonding part 10 is demonstrated.

  First, the body portion 12 constitutes the center of the bonding portion 10, and a crimping portion 14 configured in the form of a metal block is provided at the lower end portion of the body portion 12. The crimping portion 14 is heated to heat the crimping portion 14. A portion 16 is provided. The heating unit 16 is preferably configured in the form of an electric heater, and an electric wire 17 for supplying electric power is connected to the heating unit 16.

  On the other hand, a connecting rod 19 is provided on the upper portion of the body portion 12. The connecting rod 19 is connected to the vertical movement unit 3 (FIG. 1) and plays a role of guiding the vertical movement of the bonding unit 10.

  The body portion 12 is provided with a left / right position adjusting screw 21 and a front / rear position adjusting screw 23. The left and right position adjusting screw 21 has a role of fixing the position after adjusting the left and right so that a partial position of the bonding portion 10 is more suitable for performing the crimping process. , After the bonding part 10 is adjusted back and forth, the position is firmly fixed.

  For this reason, the left / right position adjusting screw 21 is provided perpendicular to the left / right direction of the bonding part 10, and the front / rear position adjusting 23 is provided perpendicular to the front / rear direction of the bonding part 10.

  The operation of the present invention configured as described above will be described below.

  As shown in FIG. 1, the size of the liquid crystal display panel 70 corresponds to the width of the mounting portion 50, and the integrated circuit elements 74 are also widely distributed on the liquid crystal display panel 70 with a certain interval. If it is, it is necessary to maximize the distance between the bonding portions 10.

  In this case, the cam plate 2 is pulled up to the maximum so that the protruding portion 3a is positioned at the lowermost portion of the moving slit 2a, thereby widening the interval between the bonding portions 10 and increasing the interval to the maximum. To be.

  On the other hand, as shown in FIG. 3, when the size of the liquid crystal display panel 70 placed on the upper surface of the erection part 50 is reduced, and the distance between the integrated circuit elements 74 is thereby reduced, the distance between the bonding parts 10. Adjustment is required.

  Thus, when adjustment of the space | interval between the bonding parts 10 is required, the pulley 7 is driven, the connection belt 9 is moved below, and the cam plate 2 is dropped.

  When the cam plate 2 is lowered, the protruding portion 3a located at the lowermost part of the moving slit 2a is guided to the moving slit 2a and moves toward the uppermost part. At this time, the cam plate 2 moves up and down. Since the horizontal movement is switched to the horizontal movement, the upward movement of the protrusion 3a is switched to the horizontal movement in which the interval between the bonding parts 10 is narrowed.

  At this time, the bonding portion 10 moves as the vertical moving portion 3 on which the protruding portion 3a is formed is guided by the guide rail 5 and moved.

  As described above, after the distance between the bonding parts 10 is adjusted by driving the horizontal moving part 4, the bonding part 10 is lowered and the integrated circuit element 74 is thermocompression bonded to the liquid crystal display panel 70.

On the other hand, the bonding apparatus according to the present invention can also perform the thermocompression bonding operation by driving only a part of the bonding part 10. That is, as shown in FIG. 4, the size of the liquid crystal display panel 70 is as shown in FIG. Although the size of the liquid crystal display panel in the example is substantially the same, when the interval of the integrated circuit elements 74 is arranged wider than the interval in FIG. The main crimping process is performed by performing thermocompression bonding on the integrated circuit element 74 in accordance with the lifting action, but the remaining part of the bonding portions 10f and 10g are fixed without moving up and down, It stops touching.

  Therefore, even for liquid crystal display panels of various sizes, the main press bonding step can be performed by adjusting the number of bonding portions 10 necessary for the press bonding process so as to correspond to the sizes.

  FIG. 5 is a view showing a bonding apparatus according to a second embodiment of the present invention, and an apparatus for adjusting the distance between bonding portions 10 is composed of a rack and a pinion gear.

  Here, the horizontal movement unit 4 includes a rack 22 provided in the frame 1, a pinion gear 20 provided in the vertical movement unit 3 and meshing with the rack 22, and a gear drive motor 21 that drives the pinion gear 20. Prepare.

  Therefore, in this embodiment, the horizontal movement can be performed independently for each bonding unit 10, and therefore, when the interval between the integrated circuit elements 74 on the upper surface of the liquid crystal display panel 70 placed on the erection unit 50 is different for each section. In addition, the pinion gear 20 is rotated by the gear drive motor 21 so that the pinion gear 20 moves horizontally on the rack 22, and thereby the interval between the bonding portions 10 is individually adjusted. Can do.

  On the other hand, in the conventional long bar type, heat is applied to the entire crimping part regardless of whether the heated crimping part and the integrated circuit element are in contact with each other, and the crimping part that contacts the integrated circuit element in this state. In this portion, a part of the heat is transferred to the integrated circuit element side, but in the non-contact portion, the heat remains as it is.

  For this reason, the temperature of the non-contact portion at the moment of contact is formed higher than that of the contacted portion, and the degree of thermal deformation in the pressure-bonding portion due to the pressurizing action is different. Is done.

  However, according to the present invention, not only can the horizontal spacing between the bonding parts 10 be adjusted, but only a part of the bonding parts 10 can be operated when the main pressure bonding process is performed on the liquid crystal display panel 70 having a small size. In addition, the position of the crimping part 14 provided in the bonding part 10 is also a position in direct contact with the integrated circuit element 74, and the crimping part 14 is not located in the non-contact part. It overcomes the problems in the prior art that impede flatness differently.

  On the other hand, the pressure bonding portions 14 (FIG. 2) of the respective bonding portions 10 are all heated to the same temperature by the heating portion 16 (FIG. 2), or are heated at different temperatures depending on the distribution of the integrated circuit elements 74. Can do.

  Further, the pressure applied when the bonding unit 10 performs the crimping process may be applied to the bonding unit 10 in the same manner, or the pressurizing process may be performed with different pressures depending on the distribution of the integrated circuit elements 74. it can.

  As described above, the reason why the temperature and pressure of the bonding part 10 are made different for each bonding part is that, if the material of the integrated circuit element 74 is not the same, the proper heating temperature and proper pressure are different for each integrated circuit element. Because.

  As shown in FIG. 6, the pressure sensor 110, the temperature sensor 120, the power supply unit 130 for supplying power to the bonding apparatus, and the operation of the bonding apparatus are operated at the input end of the control unit 100 of the bonding apparatus of the present invention. The control unit 100 includes an up / down moving unit 3, a horizontal moving unit 4, and a heating unit 16.

  Therefore, when the integrated circuit elements 74 made of different materials are distributed, an appropriate heating temperature is set according to the distribution, and the temperature sensor 120 senses whether or not the appropriate temperature has been reached and displays the information. The temperature is transmitted to the control unit 100, and the temperature of the heating unit 16 is adjusted so that the heating temperature is appropriate for the adhesion of each integrated circuit element 74.

  On the other hand, the pressure sensor 100 senses data necessary for pressure adjustment, such as a repulsive force transmitted to the crimping portion when the crimping portion and the integrated circuit element are in contact, and transmits the data to the control unit so that the pressure is adjusted. However, when the repulsive force differs depending on the integrated circuit element because the material of the integrated circuit element is different, the different pressing force is applied through the horizontal moving part 3 connected to the bonding part corresponding to each integrated circuit element. To have.

  Hereinafter, the ACF pressure bonding step, the integrated circuit element temporary pressure bonding step, the main pressure bonding step, and the PCB adhesion step will be described with reference to the drawings.

  As shown in FIG. 7, the ACF 72 is attached to the circuit pattern (not shown) of the lower liquid crystal display panel 70b of the double liquid crystal display panels, and as shown in FIGS. The ACF 72 attached to the liquid crystal display panel 70b is preheated using the preheating head 200 that is a thermocompression bonding means.

  Here, the ACF (anisotropic conductive film) 72 is obtained by dispersing conductive particles in a thermosetting or thermoplastic resin film. A realistic connection.

  Thus, the ACF 72 covers the circuit pattern 71 formed on the liquid crystal display panel 70b by the preheating operation after the ACF 72 is attached.

  Thereafter, as shown in FIG. 10, the integrated circuit element 74 is attached onto the ACF 72 and temporarily bonded. The integrated circuit element 74 used here is provided in the TCP form.

  TCP refers to an integrated circuit element 74 mounted on a rectangular FPC (flexible circuit board) 76 having a wiring pattern formed on an insulating film such as polyimide, and an output terminal along one side of the integrated circuit element. A plurality of 74a are provided, and a plurality of input terminals 74b are provided on the opposite sides.

  Therefore, the output terminal 74a of the integrated circuit element 74 is mechanically and electrically connected to the circuit pattern formed on the liquid crystal display panel 70b, and the input terminal 74b of the integrated circuit element 74 is connected to the PCB that transmits the drive signal by ACF. The connection is made in the same way as the connection method between the liquid crystal panel and the TCP.

  On the other hand, COF is substantially the same as the structure of TCP. However, since FPC used for COF is thinner than FPC used for TCP, there is a feature that it is more flexible.

  On the other hand, as shown in FIG. 11, the output terminal 74a of the integrated circuit element 74 and the circuit pattern 71 of the liquid crystal display panel 70b are aligned using a CCD (charge coupled device) or the like, and then temporarily crimped to the integrated circuit element 74. Do.

  Thereafter, as shown in FIG. 12, the main crimping to the integrated circuit element 74 is performed using the bonding portion 10, and by this final crimping process, as shown in FIG. 13, the output terminal 74 a of the integrated circuit element 74. Are electrically connected to the circuit pattern 71 of the liquid crystal display panel 70b.

  That is, as shown in an enlarged view by a broken-line circle in FIG. 13, the ACF 72 is formed by including conductive particles 72b in a thermosetting or thermoplastic resin film 72a, and the bonding portion 10 (FIG. 10). A plurality of conductive particles 72b are interposed between the circuit pattern 71 and the output terminal 74a of the integrated circuit element 74 by a thermocompression action, thereby realizing electrical connection therebetween.

  When the main crimping process of the integrated circuit element 74 is completed in this way, the input signal transmitting PCB 76 is connected to the input terminal of the integrated circuit element 74 using the thermocompression bonding tool 202 as shown in FIG.

  Instead of using such a long bar type thermocompression bonding tool 202, thermocompression bonding may be performed using a plurality of crimping portions 14 (FIG. 12) and ACF according to the present invention. The method may be the same as the method in which the integrated circuit element 74 is thermocompression bonded to the liquid crystal display panel 70.
