Description

Technical Field

[0001] This utility model relates to the field of carrier belt manufacturing technology, specifically to a track support mechanism inside a COF carrier belt baking oven. Background Technology

[0002] In the COF carrier tape manufacturing process, it is usually necessary to apply adhesive to the side containing the metal circuitry and chips, and then cure the adhesive. Current technology typically uses an oven to dry and cure the adhesive on the COF carrier tape surface. The oven has three layers of tracks, such as... Figure 1 As shown, the COF carrier tape is continuously conveyed along the track while maintaining a material state. The COF carrier tape is dried by the flowing hot air. In order to improve the yield of COF carrier tape, the conveying track usually only supports the non-working areas on both sides of the COF carrier tape. Due to the limited support area, the middle of the COF carrier tape will bend downward due to the weight of the chip. When passing through the second layer of the track, the bending degree of the carrier tape increases because the chip is facing downward, which poses a risk of the carrier tape falling off the track. Utility Model Content

[0003] The purpose of this invention is to provide a track support mechanism inside a COF carrier baking oven to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a track support mechanism inside a COF carrier baking oven, comprising multiple sets of support fixtures evenly distributed along the length of the second-layer track. Each support fixture includes a main body base symmetrically arranged on both sides of the track. One end of the main body base is provided with a first connecting platform that cooperates with the upper end of the track, and the other end is connected to a support roller for supporting the carrier belt. The support roller is connected to the main body base through a second connecting platform. The end of the second connecting platform away from the main body base is provided with an installation groove, and a pin is fitted in the installation groove. The support roller is sleeved on the pin and fixed to the second connecting platform.

[0005] The following improvements are made in this application: the second connecting platform has limit holes on both sides of the end away from the main body base, the limit holes are connected to the mounting groove, and the limit holes are provided with insert rods.

[0006] The following improvements are made in this application: the pin includes a connecting part and an adjusting part. The connecting part corresponds to and cooperates with the mounting groove. The diameter of the adjusting part is larger than the diameter of the connecting part. A slot is provided on the connecting part to cooperate with the insert rod. The supporting shaft wheel is fitted onto the pin and then inserted into the mounting groove to connect with the main body base. The insert rod passes through the limiting hole and is inserted into the abutment hole to limit and fix the pin.

[0007] The following improvements are made in this application: the supporting shaft wheel includes an inner column and an outer wheel, the outer wheel is fitted on the outside of the inner column, and the inner column has a through hole in the middle that mates with the connecting part.

[0008] The following improvement is made in this application: an arc-shaped groove is provided on the inner side of the end of the second connecting platform near the main body base.

[0009] The following improvements are made in this application: a threaded hole is provided on the first connecting platform, a hand-tightening screw is fitted in the threaded hole, and a bolt hole is provided at the top of the track to cooperate with the hand-tightening screw.

[0010] Compared with the prior art, this utility model provides a track support mechanism inside a COF carrier baking oven, which has the following advantages:

[0011] This invention provides further support for the COF carrier belt by setting a support fixture on the conveyor track, ensuring the level of the carrier belt and preventing it from derailing due to increased bending when passing through the second layer of the track. Simultaneously, the contact with the COF carrier belt is achieved through a rolling mechanism, avoiding excessive friction and scratching of the carrier belt surface. The contact area between the support roller and the COF carrier belt is also small, allowing hot air to flow through the space between the support fixture and the carrier belt, thereby drying and curing the adhesive on the carrier belt surface and effectively preventing static electricity from affecting the quality of the carrier belt.

Detailed Implementation

[0018] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0019] like Figure 2-5 As shown, a COF carrier baking oven internal track support mechanism includes multiple sets of support fixtures 1 evenly distributed along the length of the second layer track. By setting the support fixtures 1 on the conveying track, further support is provided for the COF carrier to ensure the level of the carrier 2 and prevent the carrier 2 from bending too much when passing through the second layer of the track and thus detaching from the track.

[0020] The support fixture 1 includes a main base 11 symmetrically arranged on both sides of the track. One end of the main base 11 is provided with a first connecting platform 12 that mates with the upper end of the track, and the other end is connected to a support roller 3 for supporting the carrier belt 2. The first connecting platform 12 is provided with a threaded hole 121, and a hand-tightening screw 6 is fitted in the threaded hole 121. The top end of the track is provided with a bolt hole that mates with the hand-tightening screw 6. The support fixture 1 is connected and fixed to the track through the threaded hole 121, the bolt hole, and the hand-tightening screw 6. The contact with the COF carrier belt is rolling, which can avoid excessive friction and scratching of the surface of the carrier belt 2. At the same time, the contact area between the support roller 3 and the COF carrier belt is also small. Hot air can flow from the space between the support fixture 1 and the carrier belt 2, thereby drying and curing the adhesive on the surface of the carrier belt 2 and effectively preventing the generation of static electricity that would affect the quality of the carrier belt 2.

[0021] The supporting axle wheel 3 includes an inner column 31 and an outer wheel 32. The outer wheel 32 is fitted onto the outside of the inner column 31. The inner column 31 has a through hole 311 in the middle that mates with the connecting part 41. The supporting axle wheel 3 is connected to the main body base 11 via a second connecting platform 13. The inner side of the second connecting platform 13 near the main body base 11 has an arc-shaped groove 133, and the outer side of the second connecting platform 13 away from the main body base 11 has a mounting groove 131. A pin 4 is fitted into the mounting groove 131. Wheel 3 is fitted onto pin 4 and fixed to the second connecting platform 13; pin 4 includes connecting part 41 and adjusting part 42, connecting part 41 corresponds to mounting groove 131, and the diameter of adjusting part 42 is larger than the diameter of connecting part 41; the second connecting platform 13 has limiting holes 132 on both sides of the end away from the main body base 11, the limiting holes 132 communicate with mounting groove 131, and a rod 5 is provided in the limiting hole 132, and a slot is provided on the connecting part 41 to cooperate with the rod 5.
