Definitions
- the present invention relates to a filter carrier in which a plurality of ventilation filters are carried on a carrier tape.
- an automobile ECU Electronic Control Unit
- an automobile electrical component such as a motor, a lamp, and a sensor
- an electric toothbrush such as a shaver
- a home appliance such as a mobile phone, a solar cell, etc.
- An opening is provided in the body for the purpose of alleviating pressure fluctuation in the housing or ventilating the inside of the housing, and the opening is closed with a ventilation filter.
- the ventilation filter prevents intrusion of foreign matter into the casing while ensuring ventilation inside and outside the casing.
- such a ventilation filter may be directly attached to the casing, or as shown in FIG. 5 of Patent Document 1, a support body attached to the casing. It may be affixed to.
- a filter carrier 10 in which a ventilation filter 30 is carried on a carrier tape 20 is prepared, and the filter carrier 10 is wound around a core 51 to form a reel.

- the ventilation filter 30 partially separated from the carrier tape 20 is picked up by the suction nozzle 61 and then conveyed onto the opening 7. Thereafter, the ventilation filter 30 is attached to the opening 7 by, for example, an ultrasonic welder 62.
- the ventilation filter 30 becomes difficult to peel off from the carrier tape 20, and the possibility of defective pickup increases. Specifically, a phenomenon occurs in which the ventilation filter 30 is folded back following the carrier tape 20 at the tip of the peeling table 52. In order to prevent this, it is conceivable to increase the tension applied to the carrier tape 20, but the system configuration becomes complicated to enable such tension control. Further, if the tension applied to the carrier tape 20 is excessively increased, the ventilation filter 30 carried on the carrier tape 20 may be deformed.
- an object of the present invention is to provide a filter carrier capable of satisfactorily peeling the ventilation filter from the carrier tape without increasing the tension applied to the carrier tape.
- the inventors of the present invention have intensively studied to achieve the above object, and as a result, thought that the above-mentioned problems could be solved if the shape of the ventilation filter was set appropriately. That is, as shown in FIG. 6, the conventional ventilation filter 30 has a circular shape, and thus this shape is considered to be a cause of difficulty in peeling. The present invention has been made from such a viewpoint.
- the present invention includes a carrier tape extending in a predetermined direction, and a plurality of ventilation filters carried on the carrier tape in a state aligned in the predetermined direction, each of the ventilation filters being one of the predetermined directions.

- the X direction the predetermined direction
- the + X direction is called the opposite direction.
- the filter carrier 1 is preferably a reel as shown in FIG.
- the end of the carrier tape 2 in the ⁇ X direction is fixed to the core body 51, and the filter carrier 1 is wound around the core body 51. That is, the + X direction is also a direction in which the filter carrier 1 is pulled out from the reel.
- the ventilation filter 3 is carried on the carrier tape 2 in a state of being aligned in the X direction.
- the ventilation filters 3 are preferably arranged in a line on a straight line, but may be arranged in a staggered pattern, for example.
- the carrier tape 2 has a relatively weak adhesive force on the surface on which the ventilation filter 3 is carried, and carries the ventilation filter 3 by the adhesion force.
- a base material coated with an adhesive can be used.
- the base material include PET (polyethylene terephthalate) and polyester such as polybutylene terephthalate, polyolefin such as polypropylene, polyethylene, and polymethylpentene, resin films such as polycarbonate, fine paper, coated paper, impregnated paper, and synthetic paper. It can be made of paper or metal foil such as aluminum or stainless steel.
- the adhesive for example, an acrylic adhesive can be used.

- the carrier tape 2 can be constituted only by a base material to which no adhesive is applied.
- each ventilation filter 3 is not particularly limited as long as it allows gas permeation.
- a filter including a resin porous membrane can be suitably used.

- Examples of the monomer constituting the polyolefin include ethylene, propylene, 4-methylpentene-1,1butene, and the like. A polyolefin obtained by polymerizing these monomers alone or copolymerizing them can be used. Moreover, the nanofiber film porous body using polyacrylonitrile, nylon, polylactic acid, etc. can also be used. Among these, a porous PTFE membrane that has a small area and can ensure air permeability and has a high function of preventing water and dust from entering the housing is preferable. For example, a PTFE porous membrane having a Gurley value of 0.1 to 500 sec / 100 mL, a water pressure resistance of 1.0 kPa or more, and a single thickness of 1 ⁇ m to 5 mm can be used.
- the resin porous film may be subjected to a liquid repellent treatment.
- the liquid repellent treatment can be performed by applying a liquid repellent to the resin porous film, drying and curing.
- the liquid repellent is only required to form a film having a surface tension lower than that of the resin porous film.
- a liquid repellent containing a polymer having a perfluoroalkyl group is suitable.

- the resin porous membrane and the breathable support material are partially joined, and the area of the joined portion is preferably 5 to 20% of the total area. This is because if the area of the joint portion is less than 5% of the total area, the resin porous membrane and the air-permeable support material are easily peeled off, and if it exceeds 20%, the water pressure resistance is lowered.
- each ventilation filter 3 is preferably 0.02 to 1 mm.
- the thickness of the ventilation filter 3 is less than 0.02 mm, there is no stiffness, and workability when handling the ventilation filter 3 is deteriorated.
- the thickness exceeds 1 mm, the unevenness of the filter carrier 1 is increased to form a reel shape. Because it becomes difficult.
- a more preferable thickness of the ventilation filter 3 is 0.05 to 0.3 mm.
- Each vent filter 3 has a shape in which the end in the + X direction is pointed toward the + X direction.
- the angle at which the end in the + X direction is sharp is preferably 90 degrees or more and 135 degrees or less.

- the polygon need not be a regular polygon in which all the vertices are inscribed in a circle, and may be a home-base pentagon or the like that is pointed in the + X direction, for example.
- the ventilation filter 3 may have a water droplet shape in which a part of a circular shape protrudes in an isosceles triangle shape.
- 2A shows a case where the angle of the end of the ventilation filter 3 in the + X direction is 90 degrees
- FIG. 2B shows a case where it is 120 degrees
- FIG. 2C shows a case where it is 135 degrees.
- the ventilation filter 3 may be supported on the carrier tape 2 in such a direction that the direction from the center of the circle to the apex of the isosceles triangle is the + X direction.
- each air filter 3 that is pointed toward the + X direction may be rounded. If it is this structure, the contact area of the edge part of the + X direction of the ventilation filter 3 and the carrier tape 2 can be decreased, and it will become easy to pick up. For this reason, workability is also improved.
- the ventilation filter 3 may be carried directly on the carrier tape 2 as shown in FIG. 3A. In this case, as shown in FIG. 5, the ventilation filter 3 is picked up by the suction nozzle 61, transported onto the opening 7, and then attached to the opening 7 by, for example, ultrasonic welding by the ultrasonic welding machine 62. .

- the end portion of the ventilation filter 3 is pointed in the + X direction, so that the carrier tape 2 carries the ventilation filter 3 toward the tip of this end portion.
- Such a filter carrier 1 is effective particularly when the ventilation filter 3 has a small rigidity (for example, when the ventilation filter is a single-layer PTFE porous membrane).
- Example 2 As a film for producing a ventilation filter, a 0.2 mm thick Nemito Denko Temish (a PET nonwoven fabric laminated on a 0.08 mm thick PTFE porous film) was prepared. As the carrier tape, a substrate made of PET and coated with an acrylic adhesive on a 0.08 mm thick substrate was used.
