[0028] like Figures 2-6As shown, a vacuum reflow furnace track adapter block includes a first docking track 1 located at the entrance or exit of the vacuum cavity, a second docking track 3 corresponding thereto, and an extension track 7 arranged between the two. The first docking track 1, the second docking track 3, and the extension track 7 collectively complete the transmission work of the PCBA board. The extension track 7 is connected to the first docking track 1 or the second docking track 3. In this embodiment, the extension track 7 is connected to the second docking track 3. The end of the docking track not connected to the extension track 7 has an obstacle avoidance gap 9 between the extension track 7; the size of the obstacle avoidance gap 9 is greater than the width of the sealing door (it needs to be noted that the sealing door is usually slidingly opened and closed).
[0029] The rear side wall of the second docking track 3 is rotationally connected with a rotating block 6, which is disc-shaped. One end of the rear side wall of the extension track 7 is fixedly connected with the rotating block 6, and the extension track 7 can be angularly switched about the rotating shaft of the rotating block 6.
[0030] The front side of the first docking track 1, the second docking track 3, and the extension track 7 is rotationally connected with at least one supporting roller 4. The supporting rollers 4 on the first docking track 1, the second docking track 3, and the extension track 7 are on the same straight line, and form the same supporting plane. During the transmission process, the end of the PCBA board is above the supporting rollers 4 and is driven by them to move.
[0031] The supporting roller 4 is connected with a driving device, which includes a gear set 2 arranged in the extension track 7 and a driving gear 5 arranged in the second docking track 3. The gear set 2 is composed of at least one gear, the number of which can be set as needed. In this embodiment, the gear set 2 is composed of two gears that mesh with each other. The supporting roller 4 of the extension track 7 is coaxially connected with one of the gears, and the other gear meshes with the driving gear 5 in the second docking track 3. The driving gear 5 is connected with a driving motor.
[0032] To avoid displacement errors during equipment operation, which can cause the obstacle avoidance gap to be too small and affect the normal closing of the sealing door, the extension track 7 is movably connected with the second docking track 3. The gear set 2 in the extension track 7 meshes with the driving gear 5 in the second docking track 3, so that the extension track 7 can be angularly switched without affecting the stable connection of the transmission structure.
[0033] The extension track 7 is switched between the working state and the non-working state by rotating about the rotating shaft of the rotating block 6. In the working state, the supporting plane of the extension track 7 is coplanar with the supporting plane of the second docking track 3. At this time, the supporting roller 4 can realize the transmission work of the PCBA board during rotation.
[0034] When the vacuum cavity entrance or exit enters the closed process, the extension track 7 enters the non-working state, the support plane of the extension track 7 is perpendicular to the support plane of the second butt joint track 3, in this state, the extension track 7 is in the storage state, so that the obstacle avoidance gap is enlarged, and the normal closing of the sealing door is ensured.
[0035] The rear side wall of the extension track 7 and the rear side wall of the second butt joint track 3 are provided with positioning bolts 8, when the extension track 7 is in the working state, the state is locked by the action of the positioning bolts 8, so that the angle switching of the extension track 7 is avoided, and the transmission work of the material is further affected.
[0036] In summary, the utility model provides a kind of vacuum reflow furnace track link block, including the first butt joint track 1 in the vacuum cavity entrance or outlet position, the second butt joint track 3 corresponding therewith and the extension track 7 being set between the two;Extension track 7 is rotatably connected with the second butt joint track 3, the gear set 2 in the extension track 7 is engaged with the driving gear 5 in the second butt joint track 3, so that the angle switching of the extension track 7 can be realized, while the stable connection of transmission structure is not affected, so that the closing and opening of sealing door and the stable transmission of PCBA board are realized, the problem that PCBA board is not stable and easily falls due to track gap in vacuum reflow furnace can be solved, and it is ensured that PCBA board can smoothly pass through each track of vacuum furnace.
