Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of braider, more specifically, the utility model relates to a braider index plate combination device. BACKGROUND

[0002] The braider is an automatic equipment for arranging and packaging small components such as electronic components, chips and LEDs in the carrier tape according to certain rules. The braider is widely used in the electronic manufacturing industry, especially in the surface mount technology, for providing pre-arranged components for the placement machine. The index plate mechanism is a key component of the braider, which is used to arrange components on the carrier tape according to specific spacing and direction.

[0003] The existing index plate mechanism is usually composed of an index plate body, a driving device, a positioning device, a clamping device and a detection device, etc. The precision and reliability of the index plate mechanism directly affect the performance and product quality of the braider. The index plate body is the core component of the index plate mechanism, which is usually a disc or a flat plate structure with multiple suction nozzles, clamping jaws or other grabbing components installed on it for grabbing and fixing products. The rotation or movement of the index plate body determines the transfer of products between different stations

[0004] In actual use, the motion trajectory of a single suction nozzle on the index plate body is usually to rotate a predetermined angle along the axis of the driving shaft as the center, then move down to a preset station to adsorb a component, then move up with the component and rotate to the upper side of the next station, move down again to place the component on the station for corresponding processing (such as calibrating the angle of the component or identifying whether there is a defect, etc.), and repeat the above motion trajectory several times to complete the screening of the components before loading into the carrier tape. Therefore, the motion trajectory of a single suction nozzle can be divided into two parts: rotation along the axis of the driving shaft as the center and straight-line movement up and down. In many high-integration braiders, the rotating driving device and the linear driving device in the index plate mechanism are usually installed below the index plate body and the multiple processing stations, and the area below the platform for installing the rotating driving device and the linear driving device in the index plate mechanism is usually used to place the carrier tape reel. Therefore, when the rotating driving device and the linear driving device in the index plate mechanism fail, the index plate body and even the processing station usually need to be removed to provide enough maintenance space for operation. Even if the load-bearing components of the processing station do not need to be removed, it is easy to touch the components during maintenance in the narrow space, which is very critical for the processing station with high installation precision. After maintenance, the installation precision of the processing station needs to be re-calibrated, which seriously affects the processing efficiency of the braider. SUMMARY
