Description of the Invention (q) The components are arranged and stored in a flat shape. As shown in FIG. 2, two conveyor belts 15 extending in the X-axis direction are disposed above the component support table 13. The actual mounting substrate 15a carrying the pupillary element is carried in from the outside of the device body 11 by the conveyor belt 15. The two above-mentioned conveyor belts 15a correspond to the size of the actual mounting substrate 15a, and are moved close to each other in the Y axis direction In order to adjust the distance between them, the drawing of the conveyor belt 15 is omitted in the first figure. In order to mount the electronic components contained in the package group at a predetermined position of the actual mounting substrate 15a, two mounting heads 16 that can move freely in the horizontal direction of the X-axis direction and the γ-axis direction are mounted on the device body 11. . In order to move the mounting head 16 in the horizontal direction, two guide rails 17 extending in the Y-axis direction are mounted on the horizontal beam 11c.

The mounting head 16 that moves in the horizontal direction while being suspended under the guide rail 19 also uses the space under the horizontal fixed beam 11c to ensure a wide movement in the X-axis direction. As shown in FIG. 4, the mounting head 16 has a gripping portion 21 for fixing a folding blocking portion 19a that can be folded along the individual guide rails 19. This holding portion 21 constitutes a mounting head body. Fig. 5 is a perspective view showing a schematic structure of the mounting head 16. Fig. 6 is an enlarged view showing the mounting head 16 of Fig. 4. As shown in FIG. 5, the holding portion 21 has two connecting portions 21 a, which are installed on the guide rail 19 and two vertical portions 21 b, which extend from the individual connecting portions 21 a in the up-down direction and a horizontal portion 21 c. 'It is connected to the vertical portion 21b. The shaft blocking portion 22 is mounted outside the lower end portion of the individual vertical portion 21b. Each of the four hollow shaft cores 23 is mounted on the individual shaft blocked portion 22 in such a manner that it can be freely folded and rotated in the direction of the individual shafts. Therefore, as shown by symbols 23a to 23h in FIG. 5, a total of eight hollow shaft centers 23 are mounted on one mounting head 16. A suction nozzle 25 serving as a work holder 24 is installed at the front end of each hollow shaft center 23. The electronic component E is held by the work holder 24. The supporting member 27 is fixed to the connecting portion 21 a of the holding portion 21. As shown in Fig. 6, the screw shaft 28 is mounted between the support member 27 and the horizontal portion 21c in a freely rotatable manner. The up-and-down moving plate 29 is coupled to the screw shaft 28 by a part of the female screw portion 29a. By rotating the screw shaft 28, the up-and-down movement plate 29 is driven.

Description of the invention (7) Guide the up-and-down moving plate 29, which will be fixed on the support member 27 The lever 30 is fitted into a through hole formed in the up-and-down moving plate 29. As shown in Fig. 7, in order to rotate the screw shaft 28, the motor 31 is fixed to the grip portion 21. The timing belt 34 is hung horizontally between a timing pulley 32 fixed on the axis of the motor 31 and a timing pulley 33 fixed on the screw shaft 28. The up-and-down moving plate 29 is driven by the screw shaft 28 in the up-down direction. As shown in Fig. 8, eight air cylinders 35 are mounted on the up-and-down moving plate 29 so as to correspond to the eight working grips 24. As shown in Fig. 6, a male air cylinder 35 formed on the outer peripheral surface of the air pressure cylinder and a vertical movement plate 29 are spirally coupled to each other, and an individual air pressure cylinder 35 is mounted on the vertical movement plate 29. The driving lever 37 is fixed to the front end of the piston rod 36 of the individual air cylinder 35. The individual driving lever 37 penetrates a slit formed in the vertical portion 21b, and protrudes beyond the vertical portion 21b. The hollow shaft center 23 passes through a through hole formed at the front end of the individual driving lever 37. As shown in FIG. 6, the large-diameter portion 38 of the hollow shaft center 23 is in contact with the driving lever 37. A compression coil spring 42 is installed between the driving lever 37 and the stopper 41 fixed to the hollow shaft center 23. A downward spring force is applied to the hollow shaft center 23 by the compression coil spring 42. As shown in Fig. 9, four solenoid valves 43 that control the supply and stop of the supply of individual compressed air are mounted on the vertical portion 21b on one side of the grip portion 21. The air supply ports of the individual solenoid valves 43 are connected via hoses to four air cylinders 35 corresponding to the four hollow shaft centers 23e to 23h. The same solenoid valve 43 is mounted on the other vertical portion 21b, and is connected to four air cylinders 35 corresponding to the four hollow shaft centers 23a to 23d via a hose.

Cioc / () () 6 A7 B7 V. Description of the invention (A?) The compressed air is supplied to the air cylinder 35 , The piston rod 36 moves forward downward, and drives the driving lever 37 downward. (Please read the precautions on the back before filling in this page.) The tension coil spring 44 is installed between the driving lever 37 and the up-and-down moving plate 29. An upward spring force is applied to the individual up and down moving plates 29. Therefore, if the supply of compressed air is stopped and the inside of the air cylinder 35 communicates with the exhaust port of the solenoid valve 43, the spring force of the coil spring 44 is tightly pulled, and the individual driving levers 37 are moved up and down relative to the upper and lower moving plates 29 . As shown in FIG. 9, one of the suction nozzle 25 that sucks air from the opening at the front end and sucks the electronic component E in a vacuum, and one of the tight handshake 26 that has a finger that can be opened and closed by air pressure. It is set at the front end of the hollow shaft center 23 as a working grip 24. As shown in Fig. 9, the tight grip 26 is mounted on one of the four hollow shaft centers 23, and the suction nozzle 25 is mounted on the other three hollow shaft centers 23. When the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints and holds the electronic component E mounted on the component support table Π with the work holding tool 24, after the mounting head 16 is horizontally moved to a predetermined position, the hollow shaft is lowered and moved. Heart 23 'After holding, the hollow shaft 23 is moved upward. When the mount 16 is moved to a predetermined position of the actual mounting substrate 15a, the hollow shaft center 23 is lowered and moved again. Therefore, although the electronic component E is held in the state of the working grip 24, the upward and downward movements and the horizontal movement are performed, but if other electronic components E are disturbed during the horizontal movement, the electronic components will be removed from the work holding fixture 24. Since it moves up and down, it is necessary to set a strict length that does not cause disturbance to the up and down movement of the work holding grip 24. For example, considering the mounting of electronic components E relative to the actual mounting substrate 15a, the paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 530526 Α7 B7 V. Description of the invention (ο) The improvement of energy efficiency is expected The work grip 24 is quickly moved up and down in a short time. In the electronic component mounting device 10 shown in the figure, the individual hollow shafts 23 are driven by a combined drive of moving the up and down moving plate 29 up and down with a motor and up and down using an air cylinder 35 mounted thereon. Although it is possible to determine the forward limit position of the piston rod 36 of the air cylinder 35 with high accuracy by bringing the piston into contact with the rod cover of the air cylinder 35, it is difficult to determine the piston rod 36 with high accuracy in the intermediate position. position. On the other hand, the number of rotations of the motor 31 can be controlled with high accuracy to stop the up-and-down moving plate 29 at an arbitrary position. Moreover, compared with the up-down moving speed of the up-down moving plate 29 of the motor 31, the forward movement speed of the piston rod 36 of the air cylinder can be easily set to a higher speed. Regarding the impact force applied to the electronic component E when the work grip 24 is moved downward to contact the electronic component E, the driving force of the motor 31 can be set smaller than the driving force of the air cylinder 35 . Therefore, as shown in the figure, the work gripper 24 is moved up and down by the driving of the compound motor 31 and the air cylinder 35, and the work gripper 24 can be moved up and down quickly on one side without being applied on the other side. The impact force is on the electronic component E. When the height of the electronic component is different due to the type of the electronic component, the lower limit position of the work holder 24 can be arbitrarily adjusted by the number of rotations of the motor 31.

As shown in the figure, the electromagnetic threshold 62 for vacuum generation and the electromagnetic threshold 63 for vacuum destruction are provided between the air supply port 61 and the suction port 46 that supply compressed air. For example, when the electromagnetic threshold 62 for vacuum generation is turned on, compressed air is blown into the ejection section 64 having a diffuser, thereby generating a vacuum in the ejection section 64. In this way, when the air in the suction port 46 flows into the spraying portion 64 through the filter 65 and the check threshold to attract the electronic component E to the front end of the suction nozzle 25, the suction port 46 becomes a vacuum state (that is, a negative pressure state). ). The pressure of the suction port 46 is detected by the pressure sensor 66 to detect whether the electronic component E is held on the suction nozzle 25 or not. When the electronic component E sucked by the suction nozzle 25 is removed, the vacuum-breaking electromagnetic threshold 63 is opened, and the compressed air from the air supply port 61 is introduced into the suction port 46. The amount of compressed air supplied to the electromagnetic threshold 63 for vacuum destruction is controlled by the variable current limiting threshold 67. The air discharged from the injection unit 64 is silenced by a muffler, and then discharged to the outside. When the suction nozzle 25 is used as the work holder 24, the suction port 46 is brought into a vacuum state to vacuum-hold and hold the electronic component E. On the one hand, when the handshake 26 is used as the work holder 24, the electromagnetic threshold 62 for vacuum generation as shown in FIG. 11 is not operated, but the electromagnetic threshold 62 for vacuum destruction is opened / closed. The compressed air is supplied to the tight grip 26 to open and close the fingers provided on the tight grip 26 to hold the electronic component E. As in the present embodiment shown in FIG. 12, the suction nozzle 25 as the working gripper 24 is composed of a straight cylindrical nozzle body 71 and an outer cylinder 72 having a cylindrical portion 72a.

Description of the Invention (/ ^) The mouth body 71 is inserted and fixed on the tip side. As shown in FIG. 12, the outer cylinder 72 is equipped with a cylindrical portion 72a. The cylindrical portion 72b is integrally formed with the hollow shaft center 23. The small-diameter hollow portion in which the cylindrical portion 72a is installed and the large-diameter hollow portion in which the cylindrical portion 72b is installed are integrally formed. As shown in Figures 13 (a) and 13 (b), by inserting a small-diameter thin tube 73 into a large-diameter straight cylindrical outer tube, in order to use the thin tube 73 in the nozzle body 71, A narrow hole 80 is formed in the nozzle body 71. In this embodiment, a gap between the inside of the thin tube 73 and the outer tube 74 can be used Partly, it is used as the pores 80. Thus, in this embodiment, as shown in FIG. 13, the suction surface 71a of the suction nozzle body 71 is formed on the porous surface. A plurality of pores 80 The side of the communication surface 71b of the nozzle body 71 provided inside is inserted and fixed to the cylindrical portion 71a provided on the front end side of the outer cylinder 72. When fixing, for example, so that the cylindrical portion is installed within 2a There will be no air leakage between the peripheral surface and the outer peripheral surface of the inserted nozzle body 71, and it will be fixed.

Description of the invention (/) (Please read the precautions on the back before filling in this page.) The communication surface 7 1B of 71 is separated from the front end side of the hollow shaft 23. The gap is formed in the space of the vacuum chamber 90. A plurality of thin tubes 73 are provided in the nozzle body. In 71, one of the pores 80 is opened toward the suction surface 71a, and the other end is opened toward the communication surface 71b communicating with the inside of the vacuum chamber 90. The plurality of fine holes 80 are conducted so that the side of the suction surface 71a and the communication surface 71b facing the inside of the vacuum chamber 90 communicate with each other. On the one hand, as shown in Figures 14 (a) and 14 (b), there is a length 1 of the pore 80, and even if one of the openings of the suction surface 71a is, for example, the suction of the electronic component E While in the occluded state, the pores 80 that are conducted without opening the openings can also attract external air, and maintain the negative pressure in the vacuum chamber 90 by the pressure loss (ΔP) generated in the pores 80 to maintain the electrons. Absorption of element E. Incidentally, when the pipe friction coefficient of the pore wall is λ, the pressure loss ΔP generated in the pore 80 can be calculated from the following relationship between the length L of the pore 80 and the diameter d of the pore 80. Furthermore, v represents the 'average flow velocity of the fluid, and g represents the acceleration of gravity. AP = X (L / d) (v2 / 2g) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The length of the pores 80 is more than the length L obtained. When the length is less than L, the pressure loss on the pores 80 opened by the unblocked openings will be small, so the attractive force necessary for the adsorption of the S-element electronic components is not maintained. For example, if the suction surface 71a is not completely closed, there will be no suction. Next, the use of the above-mentioned electronic component mounting apparatus 10 is described in order to mount the electronic component E on the actual mounting substrate 15a.

As shown in the figure, when two mounting heads 16 are provided, the horizontal movements of the individual heads are controlled without causing the mounting heads 16 to interfere with each other. First, the individual mounting head 16 is moved to a predetermined position of the component supply section 14. It is decided to set the position of one of the eight working grips 24 of the mounting head 16 above the predetermined electronic component E. In this state, the air cylinder 35 corresponding to the work grip 24 is operated, and the hollow shaft center 23 is moved downward through the driving lever 37. Then, the motor 31 is driven to move the upper and lower moving plates 29 downward. The control signal is transmitted to the predetermined vacuum generating solenoid valve 62 in the ejection type vacuum pump 45 at a predetermined timing ′. The compressed air is supplied to the ejection portion 64 so that the suction port 46 becomes a negative pressure state. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, after the hollow shaft 23 is moved downward by the air cylinder 35, the hollow shaft 23 is moved downward by the motor 23 so that the front end of the suction nozzle 25 contacts When the electronic component E reaches the suction nozzle 25, the suction nozzle 25 can be prevented from applying an impact force to the electronic component E. The error between the stop position at the front end of the suction nozzle 25 and the surface of the electronic component E can be removed by lifting the hollow shaft 23 to resist the spring force of the spring 42. For example, when the suction nozzle 25 contacts the surface of the electronic component E, the electronic component E is vacuum-sucked to the front end of the suction nozzle 25 by the air flowing into the interior from the front end.

Description of the invention (/ 7) 74, along the direction of the tube, a partition plate is provided to form a fine hole 80. Furthermore, it is also possible to The side surfaces of the angular thin tube 82 are adhered to each other so that the suction surface 71a is formed on the porous surface of the angular opening. In addition, although the diameters of the plurality of thin tubes 73 are the same, thin tubes of different diameters can also be used. : It is also possible to arrange a large-diameter thin tube in the center of the outer tube 74 and a plurality of small-diameter thin tubes 73 along the circumference of the large-diameter thin tube 73. Furthermore, although the above-mentioned electronic Component mounting device is suitable for mounting multiple types of electronic components E It is mounted on the actual mounting substrate 15a, but it is also applicable when a specific electronic component is mounted on a test board as a mounted component. In addition, although eight hollow shaft centers 23 are provided on one mounting head 16, You can set any number of hollow shafts (not limited to eight). In addition, as shown in the figure, the work holder 2 is installed at the lower end of the hollow shaft 23 as a vertical moving plate, and the hollow shaft is used. The hole in 23 guides the fluid that causes the working grip 24 to move, but the axis may not be hollow, or it may correspond to the working grip 24 installed at its lower end, and the fluid is directly supplied through a hose or the like. Because the suction nozzle of the present invention, when a part of the opening portion of the suction surface is closed, the pressure loss caused by the thin tube that is conducted to the unclosed opening portion of the suction surface can be maintained in the vacuum chamber. The necessary negative pressure for suction makes it possible to suck the electronic component on a part of the suction surface. When a part of the opening on the suction surface becomes closed, it can be conducted to the unclosed opening on the suction surface.
