Sealing equipment for electronic component carrier tapes

Abstract

A sealing device for electronic component carrier tape includes two support bases, two sealing bases, two lifting mechanisms, a guide mechanism located above the sealing bases, and two translation mechanisms. Each support base includes a base platform, two guide rods inserted into the base platform, a lifting platform located above the base platform through which the guide rods pass, and two carrier platforms respectively disposed on the lifting platforms. Each sealing base includes a main body disposed on a corresponding guide rod, and a sealing blade fixed to the main body. Each translation mechanism includes at least one slider disposed on one of the carrier platforms, at least one linear guide rail, a drive member, and a screw that drives one of the main bodies. The drive member can drive the screw to rotate, thereby causing the main bodies to move closer or further apart, to adjust the distance between the carrier platforms and the sealing blades.

Claims

1. A sealing device for an electronic component carrier tape, comprising: two support seats spaced apart from each other along a width direction, each support seat including a base platform, two guide rods inserted into the base platform and extending upward from the base platform, a lifting platform located above the base platform through which the guide rods pass, and two platforms respectively disposed on the lifting platform; two sealing seats respectively disposed opposite the support seats, each sealing seat including a main body disposed on the guide rods of the corresponding support seat, and a sealing blade fixed to the main body and located above the platform; two lifting mechanisms respectively disposed on the support seats, each lifting mechanism being controllable to drive the lifting platform of the corresponding support seat to move up and down relative to the base platform along the guide rods, thereby driving the corresponding platform upward toward the sealing blade of the corresponding sealing seat, or driving the platform downward away from the sealing blade; A guiding mechanism, located above the sealing seats, is provided for each sealing seat to be movable along the width direction. The guiding mechanism includes a top seat, two side seats respectively disposed on opposite sides of the top seat and extending downward along the width direction, and two connecting members passing through the top seat and respectively connected to the main seats. The top seat defines at least one groove extending along the width direction for the connecting members to pass through. Two translation mechanisms, each translation mechanism including at least one slider disposed on the platform of one of the support seats, at least one linear slide rail extending along the width direction and movably disposed for the at least one slider, a driving member disposed on the guiding mechanism, and a screw that can be driven to rotate by the driving member and linked to the main seat of one of the sealing seats; and a base plate, the base plate having a plurality of grooves for the linear slide rails to be inserted into, and two slots respectively for the lifting platforms to pass through.

2. The sealing device as described in claim 1, wherein, Each support's lifting platform defines two downward-facing inner chambers. Each lifting mechanism includes two air nozzles disposed along the width direction on the outside of the lifting platform and respectively communicating with the inner chambers, and two pistons connected to the base and respectively extending into the inner chambers.

3. The sealing device as described in claim 2, wherein, Each piston of each lifting mechanism has an extension rod extending upward from the base to the corresponding inner chamber, and a plug disposed at the top of the extension rod. When air is introduced into the inner chambers through the air nozzles, the corresponding lifting platform is pushed upward.

4. The sealing device as described in claim 1, wherein, The guiding mechanism also includes a plurality of lifting rods that pass through the side seats and extend vertically, and two bases located on opposite sides of the support seats and the sealing seats along the width direction, for the lifting rods to be inserted.

5. The sealing device as described in claim 4, wherein, The guiding mechanism also includes a plurality of slide rods that pass through the main seats along the width direction and are respectively disposed on the side seats at both ends.

6. The sealing device as claimed in claim 1, wherein, Each sealing seat also includes two return springs respectively sleeved on the guide rods of the corresponding support seats. The top end of each return spring abuts against the main seat body, and the bottom end extends through the platform and abuts against the lifting platform.

7. The sealing device as claimed in claim 1, wherein, Each sealing seat also includes a heating rod that extends and is inserted into the sealing blade.
