れている。(Prior Art) In the manufacturing process of cathode ray tubes, many transfer devices are used due to automation. In particular, when transferring a cathode ray tube or a panel that is a component thereof, the method of holding the top surface of the panel by vacuum suction is the simplest and widely used method.

通常はゴムが使用される。Fourth, as shown in the figure, this vacuum suction method involves attaching a suction pad 2 with an open bottom to the lower end of a movable arm 1, and connecting an exhaust vibrator 3 to the center of this suction pad 2. , the suction pad 2 is pressed against the top surface of the panel 5 of the cathode ray tube 4, and the interior of the suction pad 2 is made negative pressure via the exhaust vibrator 3, and the cathode ray tube 4 is suctioned and held;
In this suction state, the cathode ray tube 4 is moved by vertically and laterally moving the arm 1. Since the suction pad 2 needs to be made of a flexible material,
Usually rubber is used.
しかし、このような装置においては、パネル５の上面に
反射防止膜等が形成されたブラウン管４を吸着保持する
と、その反射防止膜等を傷つける場合がある。However, in such a device, if the cathode ray tube 4 on which an antireflection film or the like is formed on the upper surface of the panel 5 is held by suction, the antireflection film or the like may be damaged.

ている。In other words, the anti-reflection film can be made by applying a powder mainly composed of sB silicon to the top surface of the panel 5 and baking it in a furnace to roughen the surface and cause diffuse reflection, or by applying a special thin film by vapor deposition, etc. There is something formed on the top surface of the panel 5. FIG. 7 shows the case where Si powder 6 is applied to the top surface of the panel 5. It prevents reflection by scattering the light that enters the top surface.

残るため不良品となってしまう。At this time, as the suction pad 2 deforms, a slight slipping phenomenon occurs at the contact portion 7 between the suction pad 2 and the upper surface of the panel 5, and the suction pad 2 scrapes the upper surface of the panel 5. As a result, the antireflection film formed on the top surface of the panel 5 may be destroyed, and this will remain as a scratch, resulting in a defective product.

comes into contact with the upper surface of the panel 5. The buffer sheet 11 is deformed due to its flexibility and comes into close contact with the upper surface of the panel 5, and the suction pad 2 comes into contact with the upper surface. In this state, exhaust pipe 3
When the inside of suction pad 2 is made negative pressure through
As shown in the figure, the suction pad 2 deforms and suctions the panel 5. In the process of deformation of this suction pad 2, tt)
Since the lii sheet 11 is in close contact with the top surface of the panel 5, no slippage occurs between the buffer sheet 11 and the top surface of the panel 5, but a slippage phenomenon occurs between the buffer sheet 11 and the suction pad 2. . Therefore, the buffer sheet 11 will not damage the top surface of the panel 5, and the suction pad 2 will not cause any damage.

パネル５を吸着保持Ｊることができる。Note that by forming the through holes 13 in the buffer sheet 11, vacuum suction can be performed more reliably, but in some cases, the through holes 13 in the [j sheet 11 may not be provided. That is, the buffer sheet 11 made of a soft material is in close contact with the top surface of the panel 5, creating a negative pressure state between the top surface of the panel 5 and the buffer sheet 11, so that the panel 5 can be held by suction even without the through holes 13. I can do it.

A buffer sheet is interposed between the top surface of the panel and the top surface of the panel, and the top surface of the panel is adsorbed through the buffer sheet, which prevents the deformation of the suction pad that occurs during suction from being transferred to the top surface of the panel, without damaging the top surface of the panel. It is possible to adsorb cathode ray tubes and their component panels, and in particular,
Special treatment, such as an anti-reflection coating on the top of the panel, can be very effective.
