Abstract

The invention provides an automatic transfer device for a silica gel charging tray, which includes a tray transport mechanism, a turntable mechanism, a comb-shaped pick-and-place plate, a tray pick-up platform, a tray pusher cylinder, and a tray pusher platform. The pan mechanism is composed of two sets of parallel four-bar mechanisms that move synchronously. The two connecting rods are driven by stepping motors. The two connecting rods are connected together to form a translation platform. The base of the turntable mechanism is fixed on the translation platform. The toothed pick-and-place plate rotates together with the rotating shaft of the turntable mechanism. Driven by the tray transport mechanism, the translation platform performs reciprocating translation. When the comb-shaped pick-and-place plate obliquely passes through the tooth side gap of the tray pick-up platform, two silica gel loading trays are removed. After the turntable mechanism turns 90 degrees, The comb-shaped pick-and-place plate passes obliquely downwards through the tooth side gap of the push plate platform and places the silicone charging tray on the push plate platform. The push plate cylinder is hinged with the push plate, and the push plate can push the silicone charge tray horizontally. Suitable location, without manual handling, reduces labor intensity and improves automation level.

Description

Silicone charging tray automatic handling device

technical field

The invention relates to a material handling device, in particular to an automatic handling device for a silica gel charging tray.

Background technique

In the production of silica gel, the silica gel particles contained in the tray need to be placed on the drying rack and enter the drying workshop for drying. At the end of the silica gel production line, the silica gel loading tray is transferred to the tray picking platform, and then the tray is manually placed on the drying rack. During the loading process of the silica gel loading tray, workers need to repeat the same actions repeatedly, which can easily cause human fatigue, excessive labor intensity and harsh working environment.

The connecting rods of the two sets of parallel four-bar mechanisms are fixedly connected to the Together they form a translation platform, the base of the turntable mechanism is fixed on the translation platform, the lower end of the rotating shaft of the turntable mechanism is connected to the output end of the stepper motor installed on the base, and the upper end passes through and is fixed on the base The bearings are fixed together with the comb-shaped pick-and-place plate. When the stepping motor drives the rotating shaft of the turntable mechanism, the comb-tooth-shaped pick-and-place plate rotates with the rotating shaft, and the pick-and-place platform is placed on the At the end of the silica gel production line, the push plate platform is placed at the front end of the drying rack and is kept level with the appropriate placement position of the silica gel charging tray on the drying rack. The comb-shaped pick-and-place plate can pass through gaps between the teeth of the pick-up platform and the push-disk platform. The push plate cylinder is hinged with the push plate.

The tray transport mechanism is a parallelogram mechanism.

The disc-taking platform has the same structure as the pushing platform, both of which are comb-shaped, and the number of tooth-shaped parts and the tooth spacing can be changed arbitrarily.

The comb-shaped part of the disk-taking platform and the disk-pushing platform is arranged at an angle of 90 ^° in the same horizontal plane.

The push disc cylinder can be a linear drive such as a hydraulic cylinder or a ball screw.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1. The automatic transfer device for silica gel charging tray realizes the mechanical automatic transfer of silica gel charging tray from the tray picking platform at the end of the production line to the pushing platform in front of the drying rack, which replaces manual handling, improves the mechanization level of the silica gel production process, and reduces It reduces the labor intensity of workers and saves production costs.

2. The combination of the tray transport mechanism composed of a double parallel four-bar mechanism and the comb-shaped pick-and-place plate can facilitate the pick-up and release of the silica gel loading tray. The overall structure is simple and the operation is stable.
