Description

The invention relates to the automation and mechanization of technological processes for the machining of parts, in particular, to equipment for carrying out the operation of degreasing parts of a semiconductor production in hot trichlorethylene, followed by drying in a stream of hot air.

A device for chemical processing of parts is known, which contains technological baths, a portable mechanism of suspensions with parts, a drive vertical guides in which a lifting-lowering body with a driving and driven sprockets connected by a chain and holders of suspensions 1 are placed,

A disadvantage of this device is the complexity and bulkiness of the design of the transfer mechanism, which is designed to transfer overall products through baths and contains an actuator. In addition, the device is in the process of operation in the zone of action of the vapors of the bath.

Closest to the present invention is a device for coating products, comprising a series of baths, a throw-over mechanism for suspensions and an actuator {2.

However, the known device does not provide for synchronous movement of the suspensions with the parts, since the drives of the grab rails, of which

consists of a throw-over mechanism; they are not tied tightly to each other. Each pair of actuators is driven by a low-voltage circuit. When moving parts there is no smoothness of rotation due to the selection of gaps in the chain.

In addition, the device has large dimensions and complex construction.

The purpose of the invention is to improve the reliability of the device by providing synchronous and smooth movement of the suspenders with details, as well as simplifying the design.

The goal is achieved by the fact that in a device for chemical processing of parts containing a series of baths arranged along the process, a mechanism for transferring suspensions with parts, guides and a drive, a mechanism for transferring suspensions is made in the form of U-shaped shafts mounted above waves perpendicular to the guides with the possibility of rotational motion, connections between each other are rigid

a pair of two tons of loosely fixed in the upper part of the shafts, each of which is rigidly connected with a guide, and counterweights located in the lower part of the U-shaped shafts.

Figure 1 shows the device, a general view; figure 2 - the same cross section.

The proposed device consists of a drive that includes an electric motor 1, a gearbox 2, a V-belt transmission 3 and a gear transmission that transfers the force to two U-shaped shafts 5 installed above the baths 6. The shafts 5 are interconnected by a bevel gear 7H on each U-shaped shaft 5 freely installed in the upper part

pipe 8, to which are attached gi

9 apart from each other. To the ends of each pair of tg are attached the guides 10, located along the row of baths and carrying suspensions 1.1 sec.

details Counterweights 12 are mounted in the lower part of the shafts to ensure smooth movement of the suspensions with parts. The device also contains loading and unloading tables.

and a heater for drying parts in a stream of hot air. The entire device is enclosed.

The device works as follows.

The rotation from the electric motor 1 through the gearbox 2, the V-belt 3 and the gear train A is transmitted to the first U-shaped shaft 5, and through the bevel gear 7 to the second

U-shaped shaft. The U-shaped shafts 5 make a rotational movement, and the guides 10, through the ti gi 9, reciprocate in the horizontal plane along a closed

circle. Making a reciprocating motion, the guides 10 capture the suspensions 11 with the parts and transfer them from one bath 6 to another according to the sequence of the technological process. Time is maintained at working positions with a time relay (not shown). Thus, the suspensions 11c parts, entering the loading table, passing the 6 degreasing baths, the calorifier get onto the unloading station and roll down the inclined chute to the operator.

In the proposed device, the design is greatly simplified and the dimensions are reduced, since it operates from a single drive. Besides

in addition, the presence of a rigid portable mechanism system and a counterweight ensures synchronism and smoothness of movement.
