Material loading trolley moving mechanism of electronic product annealing or sintering furnace

Abstract

The invention discloses a material loading trolley moving mechanism of an electronic product annealing or sintering furnace, and belongs to the technical field of industrial stoves. The material loading trolley moving mechanism comprises a moving seat, a sliding sleeve, a sliding sleeve rotating device, a moving seat driving device and a push head; two sides of the moving seat are matched on a rail in a sliding way; one end of the sliding sleeve is arranged on the moving seat and extends into a seat cavity of the moving seat, while the other end is connected with the sliding sleeve rotating device; the sliding sleeve rotating device is fixed on a terrace or a support additionally arranged; the sleeve body of the sliding sleeve extending into the seat cavity of the moving seat is provided with a propelling head; the moving seat driving device is fixed on the terrace or a support additionally arranged and is connected with the sliding sleeve; and the push head is fixed on the bottom of a material loading trolley and is matched with the propelling head. The material loading trolley moving mechanism has the advantages of enabling the material loading trolley accurately positioned and not move about, and avoiding asynchrony between material loading trolleys.

Description

technical field [0001] The invention belongs to the technical field of industrial furnaces, and in particular relates to a moving mechanism for a loading trolley of an electronic product annealing or firing furnace. Background technique [0002] Electronic product annealing in the prior art or the structure of the moving mechanism of the loading trolley of sintering furnace are: respectively set tooth on a pair of guide rails corresponding to each other on the grate (also claiming support foot) that is fixed on body of furnace. A motor is arranged on the loading trolley, and a gear matched with the aforementioned rack is fixed on the motor shaft of the motor. The loading material carries electronic products such as electronic ceramics, ferrite or liquid crystals to be annealed or fired. The glass substrate of the display screen enters from the entrance of the furnace body, and goes out from the exit of the furnace after being heated, kept warm, cooled and cooled in each temp...

Problems solved by technology

However, in the actual use process, the effect of synchronous movement between the loading trolleys is not ideal, because it is difficult for the motors on each loading trolley to work at the same time when starting, and there is often an amount of advance or lag. The greater the number, the greater the cumulative error; in addition, the wear degree of the gear and the rack will be different, for example, some gears on the loading trolley wear more, while others do not, resulting in load The trolley cannot move in step

Due to the above two factors, it often happens that the same loading trolley rides across two areas, that is, two different temperature zones, which has a serious impact on the annealing or firing quality of electronic products, and even makes the entire vehicle product scrapped.

[0003] With the gradual popularization of flat-panel TVs, the annealing or firing requirements for plasma display (PDP) glass substrates are more stringent. If the loading trolley cannot run synchronously, it cannot adapt to the annealing or firing of glass substrates
