  However, the configuration described in Patent Document 1 includes a spline shaft, a feed screw shaft, a nut, and a rotation transmission means for transmitting at a required rotation ratio so that each crimping means is moved by a feed screw at the time of pitch switching. Because of the complicated configuration, the cost increases and maintenance and inspection takes time, and the reference position at the time of pitch switching is determined by the configuration of the feed screw, so it is virtually impossible to set the reference position arbitrarily. This is possible, and may not be applicable depending on the type of board, and there is a problem in that it is not easy to use.

  Further, in the configuration described in Patent Document 2, each crimping tool is configured to be movable independently, so that the placement reference position and pitch of the crimping tool can be arbitrarily set. As a means, each crimping tool is provided with a nut and a feed screw that is screwed to the nut. Therefore, there is a problem that a plurality of feed screws are arranged in parallel.

  In addition, the guide portion includes at least two guide rails arranged in parallel with a space therebetween, and when the rack is arranged in parallel between the two guide rails, the crimping unit is engaged with the rack and the pinion. While being movable, high support rigidity of the crimping unit can be ensured, and highly precise crimping can be secured.

  In addition, if each crimping unit is provided with a fixing means for braking and fixing at an arbitrary position of the guide portion, the drive motor and the pinion are connected by a flexible shaft having flexibility and small rotational position rigidity, and during the crimping process. In addition, it is possible to eliminate the risk of positional displacement in the crimping unit before and after that, and to ensure highly accurate crimping.

  In addition, if the pinion is equipped with a pair of gears that are rotationally biased in the circumferential direction so as to eliminate backlash between the rack teeth, the positioning accuracy decreases due to backlash between the pinion and the rack. Can be prevented.

  The crimping method of the present invention is a crimping method in which a plurality of components mounted on a plurality of mounting parts arranged at arbitrary pitch intervals on the side edge portion of the substrate are crimped by a plurality of crimping units of the above-described crimping apparatus.

The substrate 2 supplied to the supply position on the side of the crimping device 1 is received on the substrate holding portion 6a and conveyed toward the crimping device 1, and is moved to the crimping device 1. It is configured so as to be transferred onto a holding stage 5a of one substrate positioning means 5.

  The plurality of crimping units 4 are supported so as to be movable along the guide portion 7 in the X-axis direction along the parallel direction of the crimping units 4. As shown in FIGS. 1 to 3, the guide portion 7 is provided with a pair of guide rails 9 and 9 on both sides in the width direction of the base plate 8 installed on the gantry 30, and on the lower end surface of the crimping unit 4. A guide block 10 that is movable along the guide rail 9 is fixed. Then, a unit pitch switching means 11 to be described later is provided for independently moving and positioning each crimping unit 4 supported in this manner and switching the pitch interval and the arrangement position of each crimping unit 4.

As shown in FIG. 3, the crimping unit 4 is provided with a lower receiving portion 13 that supports the mounting portions 3 a and 3 b of the substrate 2 from the lower side of a substantially L-shaped main body frame 12 made of a rigid body. The crimping head 15 disposed immediately above is supported by the main body frame 12 via the guide block 14 so as to be movable up and down. On the side of the main body frame 12 on which the crimping head 15 is disposed, a pressing means 16 such as an air cylinder that applies a pressing force for pressing the component 3 in the Z-axis direction to the mounting portions 3a and 3b of the substrate 2 is arranged. It is installed. In order to transmit the force generated by the pressing means 16 to the crimping head 15, the intermediate portion 17 a of the lever 17 is pivotally supported on the upper end portion of the main body frame 12, and one end 17 b of the lever 17 is connected to the upper end 16 a of the retracting portion of the pressing means 16 The other end 17c is pivotally connected to the upper end of the crimping head 15, and the crimping head 15 is moved downward by the extending operation of the pressing means 16 so that the required addition is performed while the crimping head 15 is in contact with the component 3. It is comprised so that a pressure can be provided.

  Further, as shown in FIGS. 1 and 3, a portal frame 18 made of a rigid member is disposed so as to surround the arrangement space of the plurality of crimping units 4, and each of the crimping units 4 is arranged on the portal frame 18. Head operation restricting means 19 is provided for restricting the movement speed (lowering speed) of each pressure-bonding head 15 by restricting the upward movement of the upper and lower ends 16 a of the pressing means 16. The head operation restricting means 19 is a rod-shaped restricting member 20 disposed so as to face the upper part of the upper and lower ends 16a of the plurality of pressing means 16, and an elevating means 21 that moves the restricting member 20 up and down at an arbitrary speed. The pressing means 16 is extended in a state where the restricting member 20 is engaged with the withdrawing / retracting portion upper end 16a, and the restricting member 20 is moved up in a desired speed pattern, whereby each crimping head 15 Can be lowered with a desired speed pattern, and each pressure-bonding head 15 can be brought into contact with the component 3 in as short a time as possible without causing damage. By being separated from the upper end 16a, the pressing means 16 can apply a desired pressure to the component 3.

  The unit pitch switching means 11 is rotatably disposed in a state in which the rack 22 is fixed in parallel between the guide rails 9 and 9 of the guide portion 7 and is engaged with the respective crimping units 4 in the rack 22. The pinion 23 and the guide unit 7 are fixedly disposed at positions separated in the Y-axis direction orthogonal to the X-axis direction, which is the longitudinal direction thereof, and the pinion 23 of each crimping unit 4 is independently rotated. A plurality of drive motors 24 to be driven and a flexible shaft 25 that connects the output shaft of each drive motor 24 and each pinion 23 are configured. The pinion 23 is fixed to one end of a rotating shaft 32 that is rotatably disposed along the Y-axis direction at the lower end portion of the main body frame 12 of the crimping unit 4, and the other end of the rotating shaft 32 is connected to the flexible shaft 25. Has been. As a result, when the pinion 23 is rotated by the drive motor 24 via the flexible shaft 25, the pinion 23 rolls on the rack 22 by meshing with the rack 22, and as shown in FIG. Moves along the guide portion 7. At that time, since the drive motor 24 and the pinion 23 are connected by the flexible shaft 25, as long as the movement range of the crimping unit 4 is within a predetermined range regulated by the length and flexibility of the flexible shaft 25, The rotational driving force by the fixed drive motor 24 can be transmitted to the pinion 23.

  For example, as shown in FIG. 1 and FIG. 2, when four crimping units 4 are arranged in parallel with a predetermined pitch interval, as shown in FIG. 6 can be moved and positioned independently along the portion 7, and as shown in FIG. 6A, the crimping unit 4 is disposed at the pitch P1, and as shown in FIG. The crimping unit 4 can be switched at a high speed to the state where the crimping unit 4 is arranged at the pitch P2 (> P1) by the operation control of each drive motor 24.

Thus, in order to perform the main pressure bonding with the same pressure bonding apparatus 1 on the components 3 mounted (temporarily pressure-bonded) on the plurality of side edge portions of the substrate 2 at different arrangement pitches, the component 3 on one side edge portion is used. After performing the main pressure bonding, the substrate 2 is rotated to perform the main pressure bonding of the parts 3 having different arrangement pitches at the other side edge portions, or the parts 3 having different arrangement pitches by changing the model of the board 2 Even when crimping is performed, the arrangement pitch of the crimping units 4 can be switched in a short time at a high speed with a simple structure in accordance with the arrangement pitch of the components 3, and high mounting efficiency can be ensured.

  Further, in the head operation restricting means 19, before and after switching of the arrangement pitch of the crimping unit 4, when each crimping unit 4 is not arranged symmetrically about the center of the regulating member 20, A biased load acts on the regulating member 20 to cause an inclination, and the position cannot be regulated with high accuracy, and there is a possibility that the contact timing of the crimping head 15 may be shifted. In the unit pitch switching device 11 of the present embodiment, It is possible to change the pitch interval of each crimping unit 4 while maintaining the state where the crimping unit 4 is symmetrical with respect to the center of the regulating member 20 and is arranged at a predetermined pitch interval. Can be eliminated.

  Next, an operation flow diagram of FIG. 7 shows the operation of the crimping step of performing the final crimping (hereinafter referred to as crimping) of the components 3 mounted on the mounting portions 3a and 3b of the substrate 2 using the crimping apparatus 1 having the above configuration. Will be described with reference to FIG. When the substrate 2 is carried into the crimping device 1 by the substrate carrying device 6 (step S1), data relating to the arrangement pitch of the mounting parts 3a and 3b of the component 3 at each side edge of the carried substrate 2 is mounted. The control means 33 (refer FIG. 1) of the crimping | compression-bonding apparatus 1 acquires from the control apparatus (not shown) which carries out overall control of the whole line (step S2). Next, the control means 33 determines from the acquired pitch data whether or not the pitch of the mounting portions 3a and 3b at the side edge portion of the substrate 2 to which the component 3 is to be crimped next is the same as the previous crimping. (Step S3), if it is the same, the process proceeds to step S5 as it is. If not, the pitch of each crimping unit 4 is switched to the unit pitch according to the pitch of the mounting parts 3a, 3b to which the component 3 is to be crimped next Switching is performed by means 11 (step S4), and then the process proceeds to step S5. In step S5, the substrate positioning means 5 performs a movement / positioning operation on the newly loaded substrate 2 or the substrate 2 after any side edge component 3 has been crimped, and then the component 3 The mounting parts 3a and 3b at the side edge of the substrate 2 to be crimped are supported by the crimping operation position of each crimping unit 4, that is, the lower surface of the substrate of each mounting part 3a and 3b is supported on the lower receiving part 13 of each crimping unit 4. Position at the position to be. Next, each crimping unit 4 is operated as described above to crimp the component 3 mounted on each mounting portion 3a, 3b of the substrate 2 (step S6). Next, in the board 2, it is determined whether or not the side edge portion to which the component 3 is not yet crimped remains (step S7), and if it remains, the process returns to step S3 and steps S3 to S7 are performed. After repeating the operation, the component 3 is crimped to all the side edge portions where the mounting sites 3a and 3b to which the component 3 is to be crimped, and the board 2 is taken out for the next process if it does not remain. Returning to step S1, carrying in the substrate 2 and repeating the above operation, the step of crimping the components 3 can be sequentially performed on any of the substrates 2 carried in.

According to the above configuration, each crimping unit 4 movable along the guide portion 7 is provided with a pinion 23 that meshes with the rack 22 parallel to the guide portion 7, and each pinion 23 is connected via the flexible shaft 25. Since the stationary drive motor 24 rotates, the crimping unit 4 moves as the pinion 23 meshes with the rack 22 and rolls, and each crimping unit 4 is controlled by the operation control of each driving motor 24. Can be moved and positioned independently and at high speed. As a result, the switching of the arrangement pitch of the plurality of crimping units 4 and the switching to an arbitrary arrangement position can be performed at a high speed with a simple structure, so that the time and efficiency of the crimping process can be shortened. Further, since only the pinion 23 is disposed on the moving crimping unit 4 side, and the drive motor 24 is disposed on the fixed side and connected to the pinion 23 by the flexible shaft 25, the crimping unit 4 can be made compact. In addition to being able to be configured, the overall configuration of the crimping apparatus 1 can be made simple, and the apparatus cost and maintenance cost can be reduced. In particular, since the crimping head 4 can be configured to have a small size in the width direction (X-axis direction), the pitch of the plurality of mounting portions 3a and 3b disposed along each side edge of the substrate 2 is small. Even in such a case, it is preferable because the pitch between the crimping heads 4 can be switched at the same time in accordance with the pitch between the adjacent mounting portions of each side edge portion, so that the crimping can be performed all at once.

  Further, the guide portion 7 is constituted by at least two guide rails 9 arranged in parallel with a space therebetween, and the rack 22 is arranged in parallel between the two guide rails 9, 9. The crimping unit 4 can be stably moved with high support rigidity while the crimping unit 4 can be moved by meshing the rack 22 and the pinion 23, and high-precision crimping can be ensured.

  In addition, when the crimping process is performed in the operation flow as shown in FIG. 7, when the component 3 is crimped to the mounting portions 3 a and 3 b on both the long side edge and the short side edge of the substrate 2, When the pitch interval and the arrangement position of the mounting portions 3a and 3b for crimping the component 3 are switched, such as when the component 3 is crimped to the substrate 2 whose model has been switched, the plurality of crimping units 4 are connected to each mounting portion 3a, Since the position can be switched automatically and at a high speed to the position corresponding to 3b, the efficiency of the crimping process can be improved.

  In the above configuration, each crimping unit 4 is positioned by a braking mechanism provided in the drive motor 24, but each crimping unit 4 can be simply fixed by rotating the pinion 23 via the flexible shaft 25. Is movable, the fixing force of the crimping unit 4 is not sufficient, and depending on the force acting during the crimping operation, there is a risk of causing a minute movement and lowering the crimping accuracy. Therefore, as shown in FIGS. 8A and 8B, it is preferable to provide each crimping unit 4 with a fixing means 26 that fixes the brake at an arbitrary position of the guide portion 7. As the fixing means 26, a brake rail plate 27 is disposed on the side surface of the base plate 8 in parallel with the guide rail 9, and a pair of brake rail plates 27 can be clamped on the body frame 12 of each crimping unit 4. A configuration in which a brake unit 28 that forms the brake piece 28a is mounted is preferable. In FIG. 8A, 25a is a safety cover tube of the flexible shaft 25.

  In the above configuration, since the pinion 23 is simply meshed with the rack 22, when the movement and position adjustment of the crimping unit 4 is performed by the drive motor 24, the space between the rack 22 and the pinion 23 is set. Due to the influence of backlash, high positioning accuracy cannot be obtained, and position adjustment may take time even when position correction control is provided by providing a highly accurate position detection means. Therefore, as shown in FIGS. 9A and 9B, the pinion 23 includes a main gear 23a coupled to the flexible shaft 25, and a sub gear 23b that is urged to rotate in the circumferential direction with respect to the main gear 23a. It is preferable that the backlash between the pinion 23 and the rack 22 be eliminated.

  In the above configuration, the pinion 23 is disposed on the horizontal rack 22, and the drive motor 24 is disposed at a position separated in the Y-axis direction that is perpendicular to the longitudinal direction of the guide portion 7. As shown in FIG. 10, the drive motor 24 is disposed in the lower base 30 where the base plate 8 is installed with the output shaft facing upward, and the rack 22 is placed vertically on the base plate 8. The pinion 23 is disposed on the pressure-bonding head 4 so as to be rotatable about the vertical axis so as to mesh with the rack 22, and the output shaft of the pinion 23 and the drive motor 24 is moved up and down. It is good also as a structure connected with the flexible shaft 25 arrange | positioned in direction direction.

  In the above configuration, the guide block 10 is mounted directly on the lower end surface of the main body frame 12 of the crimping unit 4 and supported so as to be movable along the guide rail 9. However, as indicated by the phantom lines in FIG. A plurality of sliders 31 that are movable along the guide rail 9 via the block 10 and that rotatably support the pinion 23 are provided, and are respectively crimped to the sliders 31 that are configured separately from the main body frame 12 of the crimping unit 4. The unit 4 may be mounted. According to this configuration, replacement, maintenance, increase / decrease, etc. of the crimping unit 4 can be easily performed.

  In the above-described embodiment, the application of the crimping device that crimps components mounted on a plurality of mounting parts arranged at arbitrary intervals on the side edge of the substrate has been described. The switching mechanism can also be applied to changing the pitch of the crimping unit in the pasting and crimping apparatus for pasting the anisotropic conductive sheet to the mounting portions 3a and 3b of the substrate 2.

  In the crimping device of the present invention, each crimping unit movable along the guide portion is provided with a pinion and meshed with a fixed rack, and each pinion is controlled to rotate by a driving motor, and each crimping unit is independently and Because it moves and positions at high speed, it is possible to switch the arrangement pitch of multiple crimping units and switch to any placement position at high speed to shorten the time and efficiency of the crimping process, and to fix the drive motor Since it is arranged on the side and connected by a flexible shaft, the crimping unit can be made compact and the overall structure can be made simple, and the cost of equipment and maintenance can be reduced. It can utilize suitably for the crimping | compression-bonding apparatus in the mounting line which mounts components in.
