- the exhaust pipe 5 is joined to the substrate 3, and after the exhaust treatment or the like between the pair of substrates 3 is performed, the exhaust pipe 5 is sealed and cut. This process of sealing and cutting the exhaust pipe 5 was previously performed by manually melting and sealing and cutting a specific portion of the exhaust pipe 5 using a gas spanner, and automatically controlling it. Is desired.
- the exhaust pipe sealing / cutting device 80 includes a casing 82 having a heat insulating structure composed of a pair of casing members 81 that can be divided into two parts, and each of the casing members 81.
- a heater (not shown) for heating the outer periphery of the exhaust pipe provided inside.
- One casing member 81 is disposed on the mounting seat 83 and the other casing member 81 is disposed on the mounting seat 84.
- an expansion cylinder 85 is interposed between the two mounting seats 83, 84.
- the cylinder body 86 is coupled to one mounting seat 84, and the piston rod 87 is coupled to the other mounting seat 83.
- the other casing member 81 moves relative to the one casing member 81, and the casing 82 as a whole can be opened and closed.
- Each casing member 81 is formed in a box shape having a semicircular cross section, and the inside thereof is filled with a heat insulating material, and each casing member 81 is closed and fitted into a substantially perfect circle.
- a semicircular groove 88 is formed.
- the heater is disposed along the semicircular groove 88.
- the exhaust pipe sealing / cutting device in the open state as shown in the figure 80 is attached to the substrate 3 by holding the substrate 3 with the tip 35 so that the casing member 81 is located on both sides of the exhaust tube 5 by the exhaust pipe sealing and cutting robot 14.
- the clip 35 is mounted by acquiring the position of the substrate 3 as image information with the camera of the robot node and moving the robot hand to that position to perform the mounting operation.
- the expansion / contraction cylinder 85 is contracted and the casing member 81 is integrated, that is, the casing 82 is closed and the through hole 8 is closed.
- the heater is energized, and the heater heats the outer periphery of the exhaust pipe 5 for a predetermined time.
- the entire circumference of the exhaust pipe 5 is uniformly heated and melted to complete the sealing. Further, when energization of the heater 5 is continued, the sealing portion is cut.
- the apparatus configured as described above can automatically control the sealing / cutting operation of the exhaust pipe 5 to improve work efficiency, and the apparatus 80 can be operated by the exhaust pipe sealing / cutting robot 14. By sequentially replacing the substrates 3 with the clips 35, it is possible to reduce the number of chip tube sealing / cutting devices 80 that are not required for each substrate 3.
- the sealing and cutting of the exhaust pipe 5 may be performed by automatic control with a panner.
- the exhaust pipe sealing and cutting robot 14 is automatically controlled by a control means such as the robot control panel 19 to seal and cut the exhaust pipe 5, and a pan that melts the exhaust pipe 5 and a base that extends the exhaust pipe 5.
- a lowering means for lowering the exhaust pipe mounting portion 6 is provided.
- the robot hand of the exhaust pipe sealing and cutting robot 14 that attaches the above-described clip 35 to each substrate 3 is equipped with a panner, and means for lowering the exhaust pipe attachment part 6 includes, for example, the exhaust pipe attachment part 6 May be attached to the overhanging portion 38 so that it can be driven up and down.
- the position control of the panner may be performed by a method similar to the automatic control for inserting the board 3 into the board loading space S described above using the image information or the automatic control for inserting the exhaust pipe 5 into the mounting hole 53. .
- the remaining exhaust pipe 5 that has been cut and remains in the exhaust pipe mounting portion 6 is first gripped by the exhaust pipe sealing and cutting robot 14 and then supplied with air, using image information obtained by the camera in the same manner. 'When the high-pressure air is removed through the exhaust pipe 58, the holding of the exhaust pipe mounting portion 6 by the annular seal 54 is released, and it will be removed from this.
- the remaining exhaust pipe 5 may be removed by the exhaust pipe handling robot 12 that supplies the new exhaust pipe 5 to the cart 2. In this way, it is possible to prevent air from flowing into the system extending from the exhaust pipe mounting portion 6 to the exhaust pump 39 as much as possible.
- Panel unloading robot 15 Robot control panel 1 9 and other control means automatically remove panels from the board mounting part 4 of the cart 2
- the actual stop position information of the cart 2 and the actual mount position information of the panel are acquired as image information, and the panel unloading robot 15 based on the actual stop position information and the actual load position information. It is provided with unloading operation setting means for outputting control information of the panel unloading operation.
- This automatic control can be achieved by the same control as the board 3 mounting operation.
- step 2 when the robot hand stops at the corrected first measurement point, the camera detects the reference mark 1H on the overhanging portion 38, and the reference mounting position and actual mounting position of the panel are detected. The amount of error in between is calculated. Further, the second measurement point that is the second reference movement stop position of the robot node is corrected based on the calculated error amount. Steps 1 and 2 determine the appropriate stop position of the robot hand relative to the actual mounting position of the panel.
- the robot hand can be moved to an appropriate position even if there are variations in the actual stop position of the cart 2, manufacturing errors, or thermal deformation of each part.
- the panel can be unloaded from the cart 2 by automatic control.
