The jig apparatus 1 includes a main body 10, a plurality of cylinders 20 held by the main body 10 described later, and a plurality of rod bodies 30 held by each of the plurality of cylinders 20. As shown in FIG. 1, the rod body 30 has a state in which it protrudes greatly from the support wall 12 of the main body 10 and a state in which it protrudes slightly.

2A to 2D are explanatory diagrams of a method of using the jig apparatus 1.
For example, the jig apparatus 1 is used in a process of manufacturing a board unit in which electronic components are mounted on a printed board. For example, the jig apparatus 1 is hold | maintained so that raising / lowering is possible by the elevator which can raise / lower vertically. As shown in FIG. 2A, the tip of the rod 30 is attached to the material R stored on the plate 3. In this case, the material R is attached only to the tip of the rod 30 in a state of largely protruding from the support wall 12 of the main body 10. The material R is an Ag paste that functions as an adhesive. Next, as shown in FIG. 2B, the tip of the rod 30 is brought into contact with the surface of the printed circuit board 5. Thereby, as shown in FIG. 2C, the material R is transferred to a predetermined portion of the printed circuit board 5. Next, the electronic component 6 is disposed on the material R transferred to the printed board 5. Thereby, the electronic component 6 is bonded to the printed circuit board 5. Thus, the jig device 1 is used as a coating device that can apply an adhesive to the printed circuit board 5. In addition, you may transfer materials other than an adhesive agent to another member using the jig | tool apparatus 1. FIG. For example, the material R may be a liquid or a paste. For example, paste cream solder may be used as the material R. The jig device 1 is also used as a device for supporting a plate-like member such as a printed board.

3A, 3B, 4A, and 4B are explanatory diagrams of the cylindrical body 20 and the rod body 30. FIG.
FIG. 3A is an explanatory diagram of the cylindrical body 20. As shown in FIG. 3A, the cylindrical body 20 includes trunk portions 21 and 22 and a throttle portion 23. The throttle portion 23 is provided between the trunk portions 21 and 22. The cylinder 20 is substantially cylindrical. Therefore, the outer shapes of the axial sections of the body portions 21 and 22 and the throttle portion 23 are substantially circular. The cylinder 20 is made of metal, for example, phosphor bronze. The trunk portions 21 and 22 have an inner circumference and an inner diameter with substantially the same length. The inner periphery of the throttle portion 23 is smaller than the inner periphery of the body portions 21 and 22. The cylindrical body 20 has a throttle portion 25 formed at the upper end and a throttle portion 26 formed at the lower end. The throttle portions 25 and 26 define introduction ports O1 and O2, respectively. The introduction ports O1 and O2 communicate with the inside of the trunk portions 21 and 22, respectively. The inner peripheries of the throttle parts 25 and 26 are smaller than the inner peripheries of the trunk parts 21 and 22, respectively. The trunk portion 21 is provided with a plurality of relief openings O3 partially. The escape port O3 will be described later.

  FIG. 3B is an explanatory diagram of the rod 30. As shown in FIG. 3B, the rod 30 has a thick part 31, a detail 32, and a middle part 33. The middle portion 33 is provided between the thick portion 31 and the details 32. The rod body 30 is made of metal, for example, stainless steel. The rod body 30 is substantially cylindrical. Therefore, the outer shapes of the axial section of the thick portion 31, the detail 32, and the middle portion 33 are substantially circular. The outer periphery of the thick portion 31 is larger than the outer periphery of the detail 32. The outer periphery of the thick portion 31 is the maximum outer periphery of the rod body 30. The outer periphery of the middle part 33 gradually decreases from the thick part 31 to the detail 32. In addition, the outer periphery of the rod body 30 means the outer periphery of the rod body 30 around the axial direction.

  4A and 4B show the cylindrical body 20 holding the rod body 30. FIG. 4A shows a state in which the rod body 30 is held by the throttle portion 23 of the cylindrical body 20. The middle part 33 of the rod 30 is sandwiched between the throttle parts 23. In other words, the throttle portion 23 is blocked by the rod body 30. As shown in FIG. 4A, the axial length of the cylindrical body 20 is longer than the axial length of the rod body 30. The inner periphery of the trunk portions 21 and 22 is larger than the outer periphery of the thick portion 31. For this reason, the trunk portions 21 and 22 allow the rod body 30 to move in the axial direction. The inner peripheries of the narrowed portions 25 and 26 are smaller than the outer perimeter of the thick portion 31. Thereby, it is possible to prevent the rod body 30 from being detached from the cylindrical body 20. The inner periphery of the narrowed portion 23 is smaller than the outer shape of the thick portion 31. For this reason, as shown in FIG. 4A, the middle portion 33 can be held by the aperture portion 23. As described above, the throttle portion 23 has a function of restricting passage of the rod body 30. In a state where the rod body 30 is held by the throttle portion 23, the rod body 30 is accommodated in the cylindrical body 20. In addition, the inner periphery of the cylinder 20 means the inner periphery of the cylinder 20 around the axial direction.

  FIG. 4B shows a state where the rod body 30 has passed through the throttle portion 23. As will be described in detail later, the rod body 30 can pass through the throttle portion 23 by performing a predetermined operation. The rod 30 passes through the throttle portion 23 and is held on the body portion 22 side. In a state where the rod body 30 is held on the body portion 22 side, most of the details 32 of the rod body 30 protrude from the throttle portion 26. The inner periphery of the introduction port O2 is larger than the outer periphery of the detail 32. Further, as described above, the inner periphery of the narrowed portion 23 is smaller than the outer periphery of the thick portion 31. For this reason, even when the rod 30 is pushed to the barrel 21 with a certain amount of force while the rod 30 is held on the barrel 22 side, the rod 30 moves to the barrel 21 side. Is restricted by the diaphragm 23. In a state where the rod body 30 is held on the body 22 side, the material R described above is attached to the tip of the detail 32, and the tip of the detail 32 is brought into contact with the printed circuit board 5. Thereby, the material R can be transferred to the printed circuit board 5.

5A, 5B, 6A, 6B, and 7 are explanatory views of the rising of the rod 30. FIG.
In these drawings, unlike FIGS. 3A, 3B, 4A, and 4B, the shapes of the cylindrical body 20 and the rod body 30 are exaggerated for easy understanding. The main body 10 has support walls 11 and 12 that face each other. The cylindrical body 20 is held so as to penetrate through the holes formed in the support walls 11 and 12. The support walls 11 and 12 are made of synthetic resin, for example. The support walls 11 and 12 hold a plurality of cylindrical bodies 20 other than those shown in the figure.

  As shown in FIG. 5A, in a state where the rod body 30 protrudes from the cylindrical body 20, the rod body 30 closes the introduction port O2. The rod 30 closes the introduction port O2 by its own weight. Specifically, the inner edge of the throttle portion 26 and the outer edge of the middle portion 33 are in contact with each other. The throttle portion 26 slightly protrudes outside the support wall 12. The tube T <b> 1 is inserted into the cylindrical body 20 so as to cover the outer periphery of the throttle portion 26. The tube T1 is connected to a pump for conveying air. In this state, air is sent from the tube T1. When air is fed from the tube T1, as shown in FIG. 5B, the rod body 30 is lifted away from the throttle portion 26 by air pressure and comes into contact with the throttle portion 23. Air flows into the trunk portion 22 from the inlet O2. The introduction port O <b> 2 is provided so that air can be introduced into the body portion 22. When the rod body 30 is raised, the thick portion 31 of the rod body 30 closes the throttle portion 23. Thereby, it is prevented that the air in the trunk | drum 22 flows into the trunk | drum 21 side. When air is further sent in this state, the air pressure in the body portion 22 becomes higher than the air pressure in the body portion 21 and the air pressure outside the cylinder body 20.

  When air is further sent into the body portion 22, the air pressure in the body portion 22 is further increased, and the inner periphery of the throttle portion 23 is expanded to allow passage of the thick portion 31 as shown in FIG. 6A. Specifically, the side wall of the cylindrical body 20 around the throttle portion 23 expands outward. In FIG. 6A, the state of the diaphragm 23 is exaggerated. When the inner circumference of the throttle portion 23 is enlarged to the extent that the passage of the thick portion 31 is allowed, the rod body 30 is sucked to the trunk portion 21 side based on the pressure difference between the trunk portion 21 and the trunk portion 22. Thereby, the rod 30 moves to the trunk | drum 21 side. Based on the pressure difference between the body part 21 and the body part 22, the middle part 33 and the detail 32 of the rod 30 pass through the throttle part 23 as shown in FIG. 6B. In this state, by stopping the supply of air from the tube T1 into the cylindrical body 20, as shown in FIG. 7, the throttle portion 23 returns to the original inner peripheral size, so that the rod body 30 has its own weight. It falls by. The throttle unit 23 holds the rod body 30. In this way, the cylinder 20 moves up and down with respect to the rod 30. The aperture 23 holds the rod 30 in a state where it is not enlarged.

  As shown in FIG. 5B, the thick part 31 closes the throttle part 23 so that the space in the trunk part 21 is sealed. In this state, when air is supplied from the tube T1 into the trunk portion 21, the atmospheric pressure in the trunk portion 21 increases. As a result, the diaphragm 23 is enlarged. In this way, the thick portion 31 blocks the throttle portion 23, whereby the atmospheric pressure in the trunk portion 21 can be increased, and thereby the throttle portion 23 can be enlarged. Since the periphery of the narrowed portion 26 is surrounded by the support wall 12, the inner periphery of the introduction port O2 does not change.

  In a state where the rod body 30 is held by the throttle portion 23, the tip of the detail 32 may or may not protrude from the cylindrical body 20. The protruding amount of the rod body 30 from the cylindrical body 20 in a state where the rod body 30 is held by the throttle portion 23 is the amount of protrusion of the rod body 30 from the cylinder body 20 in a state where the rod body 30 is held on the body portion 22 side. What is necessary is just to be smaller than protrusion amount.

  Here, the possibility of closing the inlet O1 during the movement of the rod 30 will be described. The raised rod 30 does not always block the inlet O1, but depending on the amount of air sent from the tube T1 and the weight of the rod 30, the cylinder 20 may block the inlet O1. In this case, the air in the trunk portion 21 is discharged from an escape port O3 provided on the side surface of the trunk portion 21. The escape port O3 is located outside the support wall 11 as shown in FIG. 6B. Thereby, even if it is a case where the rod 30 raises and the inlet O1 is blocked | closed, the atmospheric | air pressure in the cylinder 20 can be pressure-reduced early to the same extent as external pressure.

  When the escape port O3 is not provided, if air is continuously sent from the tube T1 into the cylindrical body 20 with the rod body 30 blocking the introduction port O1, the pressure inside the cylindrical body 20 is changed to the cylindrical body. It becomes larger than the atmospheric pressure outside 20. Thereby, a load is applied to the cylindrical body 20. In particular, when the cylinder 20 is formed of a thin material, a problem may occur. However, since the escape port O3 is provided in the present embodiment, the inside of the cylinder 20 can be depressurized at an early stage and the load on the cylinder 20 can be reduced even when the rod 30 blocks the introduction port O1.

  Further, when the escape port O3 is not provided, there is a possibility that the throttle portion 23 is maintained in an enlarged state while the rod 30 closes the introduction port O1 and air is sent into the cylindrical body 20. As a result, there is a risk that the rod body 30 once raised to the trunk portion 21 side will fall again due to its own weight and fall to the trunk portion 22 side. However, since the escape port O3 is provided in the present embodiment, the inside of the cylindrical body 20 can be quickly depressurized even when the rod body 30 blocks the introduction port O1, and the throttle portion 23 is immediately restored to the original shape. Can be restored. Thereby, before the raised rod body 30 falls again by its own weight, the throttle portion 23 can be returned to the original shape, and the lowering of the rod body 30 can be restricted.

  Further, since the escape port O3 is provided, the inside of the cylindrical body 20 can be depressurized immediately when the rod body 30 is raised even when the rod body 30 does not block the introduction port O1. As described above, the inner periphery of the narrowed portion 23 before enlargement is smaller than the inner periphery of the thick portion 31 but larger than the inner periphery of the detail 32. Therefore, from the viewpoint of preventing the rod body 30 from descending, it is desirable that the throttle portion 23 is restored to its original shape immediately when the rod body 30 is raised and the middle portion 33 passes through the throttle portion 23. By providing not only the inlet port O1 but also the escape port O3 on the body portion 21 side, the inside of the cylindrical body 20 can be decompressed quickly. Thereby, the throttle part 23 can be returned to the original shape at an early stage, and the rod body 30 can be prevented from descending again and moving to the body part 22 side.

8A, 8B, 9A, and 9B are explanatory views of the lowering of the rod 30. FIG.
As shown in FIG. 8A, the tube T1 is inserted into the cylindrical body 20 from the throttle portion 25 side. At this time, the tube T1 is inserted into the cylindrical body 20 so as to close the escape port O3. In this state, air is sent from the tube T1. Air is supplied into the body portion 21 from the introduction port O1. As described above, the introduction port O <b> 1 is provided to introduce air into the body portion 21. Since the throttle portion 23 is blocked by the rod body 30, the air pressure inside the body portion 21 becomes larger than the air pressure inside the body portion 22 and the air pressure outside the cylinder body 20. Further, when air is supplied into the body portion 21, the throttle portion 23 expands to such an extent that it can pass through the rod body 30, as shown in FIG. 8B. When the throttle 23 is enlarged, the rod 30 passes through the throttle 23 based on the pressure difference between the barrel 21 and the barrel 22 and the weight of the rod 30. In this state, by stopping the supply of air from the tube T1 into the cylindrical body 20, the rod body 30 is held on the body 22 side as shown in FIG. 9A. In this way, the cylinder 20 is lowered with respect to the rod 30.

  FIG. 9B is a diagram when an upward force is applied to the rod body 30. As described above, the inner periphery of the narrowed portion 23 is smaller than the outer periphery of the thick portion 31 in the normal state. For this reason, the restricting portion 23 restricts the lifting of the rod 30. For example, when the jig apparatus 1 is used for transferring material to another member, when the material is applied to the tip of the rod 30 or when the tip of the rod 30 is brought into contact with another member. The upper force acts on the rod 30. Even in such a case, the restricting portion 23 restricts the rising of the rod 30.

  As shown in FIGS. 9A and 9B, the rod body 30 held on the body 22 side is allowed a stroke in a predetermined range in the axial direction. This is because the axial length of the body portion 22 is longer than the axial length of the thick portion 31. Thereby, for example, when the jig apparatus 1 is connected to an elevator or the like and moved up and down to bring the tip of the rod body 30 into contact with another member, it is possible to prevent the rod body 30 from being overloaded.

  As shown in FIG. 8A, when the middle portion 33 closes the throttle portion 23, the space in the trunk portion 22 is sealed. In this state, air is supplied from the tube T <b> 1 into the trunk portion 22, thereby increasing the atmospheric pressure in the trunk portion 22. As a result, the diaphragm 23 is enlarged. In this way, the middle portion 33 closes the throttle portion 23, whereby the atmospheric pressure in the trunk portion 22 can be increased, and thus the throttle portion 23 can be enlarged.

  As described above, the cylindrical body 20 holds the stored rod body 30 so as to be movable up and down. As shown in FIG. 1, the main body 10 is provided with a plurality of cylindrical bodies 20 and rod bodies 30 in a state where the cylindrical body 20 and the rod body 30 are paired. Thus, the cylinder 20 holding the rod 30 so as to be movable up and down is provided for each rod 30. For this reason, the freedom degree of the arrangement position of the cylinder 20 and the rod 30 in the main body 10 is improved.

  For example, in the case of a mechanism in which a plurality of cylinders 20 are held by a common mechanism so as to be movable up and down, the arrangement position of the cylinders 20 is restricted by this mechanism. However, since the rod body 30 is provided so as to correspond to each cylinder 20 as in the present embodiment, the degree of freedom of the arrangement positions of the cylinder 20 and the rod body 30 is improved.

  As shown in FIGS. 7 and 8A, the throttle portion 23 can hold the rod body 30 in an unexpanded state. Thereby, it can prevent that the rod body 30 rattles in the cylinder 20.

FIG. 10 is an explanatory diagram of another example of the method for lowering the rod 30.
The rod body 30 may be pushed downward by inserting the rod L into the introduction port O1. In this case, the inner edge of the throttle part 23 slides on the middle part 33 of the rod 30, and the inner periphery of the throttle part 23 expands to the outer periphery of the thick part 31. The rod 30 may be lowered by such a method.

11A and 11B are explanatory views of a modified example of the jig apparatus 1 according to the first embodiment.
As shown in FIG. 11A, an outer cylinder 40 that covers the outside of the cylinder 20 is provided. The outer cylinder 40 is cylindrical. The material of the outer cylinder 40 is a metal, for example. The outer cylinder 40 is thicker than the cylinder 20. The outer cylinder 40 has higher rigidity than the cylinder 20. The outer cylinder 40 is held by the support walls 11 and 12. The support wall 11 between the cylinder 20 and the outer cylinder 40 is partially provided with a plurality of communication holes 11a1. The communication hole 11a1 has a function of communicating the space S surrounded by the outer cylinder 40, the cylindrical body 20, and the support walls 11 and 12 with the outer space. The outer cylinder 40 slightly protrudes from the support wall 11.

  When raising the rod 30, as shown in FIG. 11B, the tube T <b> 1 is inserted into the cylinder 20 from the throttle portion 26 side, and the tube T <b> 2 is inserted into the inner edge of the outer cylinder 40 from the support wall 11 side. A pump capable of sucking air is connected to the tube T2. In this state, air is supplied from the tube T1 into the cylindrical body 20, and air in the space S is sucked from the tube T2. By sucking air in the space S from the tube T <b> 2, the air pressure in the space S becomes lower than the air pressure outside the outer cylinder 40. Further, when air is supplied from the tube T <b> 1, the atmospheric pressure in the body portion 22 becomes lower than the atmospheric pressure outside the outer cylinder 40. Thereby, the expansion deformation | transformation of the aperture | diaphragm | squeeze part 23 becomes easy. The tube T2 also sucks air in the body portion 21. Thereby, the atmospheric | air pressure in the trunk | drum 21 becomes lower than an external atmospheric pressure. For this reason, the pressure difference between the body part 21 and the body part 22 is increased. Due to this atmospheric pressure difference, the rod 30 moves from the barrel 22 side to the throttle 23 when the throttle 23 is enlarged. In this way, the rod body 30 is raised.

FIG. 12 is an explanatory diagram of the jig apparatus 1a according to the second embodiment.
In addition, about Example 2, the description similar to Example 1 is attached | subjected, and the overlapping description is abbreviate | omitted by attaching | subjecting the same code | symbol. Heaters 50a and 50b are disposed on the support wall 11 and the side wall of the main body 10, respectively. The heaters 50a and 50b are, for example, cartridge heaters or ceramic heaters, but are not limited thereto. The heaters 50a and 50b utilize heat generated by electric resistance, for example. The heaters 50a and 50b are for heating the throttle portion 23 of the cylindrical body 20 described above. By heating the throttle part 23, the throttle part 23 expands and the expansion of the inner periphery of the throttle part 23 can be promoted. Thereby, when moving rod 30 using tube T1 mentioned above, diaphragm 23 can be changed easily and rod 30 can be moved easily.

  Here, when the throttle part 23 is heated, the rod 30 is also heated. For this reason, the cylindrical body 20 is formed of a material having a thermal expansion coefficient larger than that of the rod body 30. This is because, when the thermal expansion coefficient of the rod body 30 is equal to or higher than the cylindrical body 20, the outer periphery of the rod body 30 is enlarged similarly to the inner periphery of the throttle portion 23. As described above, the material of the cylindrical body 20 is, for example, phosphor bronze, and the material of the rod body 30 is stainless steel. The thermal expansion coefficient of phosphor bronze is larger than that of stainless steel.

13A and 13B are first and second modifications of the second embodiment, respectively.
As shown in FIG. 13A, the heater 50 c is provided in the main body 10. Specifically, the heater 50 c is provided between the support walls 11 and 12 so as to sandwich the plurality of cylinders 20. The heater 50a is provided outside the support wall 11, and is provided so as not to block the escape port O3 of the cylindrical body 20. Thereby, the cylinder 20 can be heated efficiently. The heater 50c is provided so as to sandwich the plurality of cylinders 20. For this reason, the cylindrical body 20 can be heated without increasing the interval between the cylindrical bodies 20 sandwiched between the heaters 50c.

  Further, as shown in FIG. 13B, the heaters 50d are provided alternately with the cylinders 20. Thereby, the cylinder 20 can be heated efficiently in a short period of time. In the second modification of the second embodiment, no heater is provided outside the support wall 11d. Thereby, the increase in the thickness of the whole jig apparatus is suppressed.

FIG. 14 is an explanatory diagram of the setting jig 100.
FIG. 14 shows a jig system including the jig apparatus 1 a and the setting jig 100. The setting jig 100 includes a main body 110 and a heater 150. The main body 110 is made of metal, for example. The main body 110 is provided with a plurality of supply holes 120. The supply hole 120 corresponds to the positions of the cylinder 20 and the rod 30 of the jig apparatus 1a. A tube T3 is connected to the setting jig 100. A pump for sending out air is connected to the tube T3. The tube T3 communicates with each supply hole 120.

  When air is sent out from the tube T3, air blows out from the supply hole 120. The jig device 1a is arranged on the setting jig 100 so that the supply hole 120 and the cylinder 20 are fitted, and air is supplied to each cylinder 20 by supplying air from the tube T3. The As a result, all the rod bodies 30 can be raised and held in the throttle portion 23. The heater 150 is for heating the air supplied into the cylindrical body 20. By supplying the heated air into the cylindrical body 20, it is possible to promote the expansion of the inner periphery of the throttle portion 23. In addition, since the main body 110 is made of metal, the main body 110 can be heated at an early stage by the heater 150, whereby the air sent out from the supply hole 120 is also heated.

15A and 15B are views showing the internal structure of the setting jig 100. FIG.
As shown in FIG. 15A, the heater 150 is fixed to the bottom surface of the main body 110. The heater 150 is, for example, a cartridge heater or a ceramic heater.
