TECHNICAL FIELD

[0001] The utility model relates to the technical field of heterojunction battery, specifically to a heterojunction battery PECVD automation PEEK improvement mechanism. BACKGROUND

[0002] Heterojunction battery is the current popular battery technology, has high efficiency, low temperature manufacturing process, no PID phenomenon, can develop to the sheet and has broad development prospect, but compared with other types of battery automation structure is complex, cause more fragments, so reducing the equipment fragment rate also became the primary task, at present, the PEEK of heterojunction CVD each section automation belt fast runway is more, all be used to contact silicon wafer, lift silicon wafer, the original PEEK both sides is right angle edge, the warping is not big, in the fast motion of the belt, right angle edge is easy to cause scratch and position deviation, to the rear station due to design defects easy to cause the edge and fragment, the scheme changes the design of PEEK for this problem, achieves the purpose of reducing scratch and fragment rate. SUMMARY

[0003] The utility model discloses a kind of heterojunction battery PECVD automation PEEK improvement mechanism, to solve the problem that the above background technology proposes that the existing battery automation structure is complex, cause more fragments.

[0004] To achieve the above object, the utility model provides the following technical scheme:

[0005] A kind of heterojunction battery PECVD automation PEEK improvement mechanism, including battery piece, the screw hole is set on the upper surface of the battery piece, the screw hole is set on the upper surface of the battery piece with multiple groups, the upper side of the screw hole is fixedly installed and is provided with PEEK, the screw hole is used to fix PEEK, PEEK is fixed to the belt of fast runway, it is convenient to install.

[0006] Preferably, the upper side of the PEEK is installed and is provided with bevel, the bevel is fixed with PEEK by welding, the bevel of the upper side of the PEEK is installed, used to lift silicon wafer, prevent silicon wafer from being contacted with fixed surface, cause scratch.

[0007] Preferably, the other end of the bevel away from the screw hole is installed and is provided with baffle, the baffle is fixed with PEEK by welding, by the baffle of installation, to effectively prevent silicon wafer from being deviated on runway.

[0008] Compared with prior art, the utility model has the advantages that:

[0009] 1. The heterojunction battery PECVD automation PEEK improvement mechanism, by replacing the new pad on the CVD each section automation fast runway, thereby reducing the silicon wafer edge, so as to reduce the purpose of the broken piece rate.
