Description

The invention relates to the technique of drying piece goods and can be used in the radio industry. A device for heat treatment of radio components with axial inputs, such as drying marking paint and varnish, contains a heating chamber with electric heaters placed inside f along the movement of electric heaters and a chain conveyor with multiple varying directions of movement and with guide parts of radio components installed along the conveyor. Known devices are characterized by insufficient reliability of operation and inconvenience of maintenance. A device for drying goods, containing a heating chamber with an electric heater inside and windows in the walls and a conveyor with drive shafts and combs, having straight lines and curvilinear sections connecting them, and fixed guides for outputting radio components {2 ;. The disadvantage of this known device is also the inconvenience of servicing the readjustment of the device during the heat treatment of products of other dimensions. The purpose of the invention is to improve the operating conditions. This goal is achieved by the fact that in a device for heat treatment of radio components with axial leads, containing a heating chamber with electrical heaters inside and windows in the walls and a conveyor with drive shafts and combs in the chamber, having straight lines and curvilinear sections connecting them, and fixed directions for outputting radio components, the guides are made of a telescopic type, mounted on the straight sections of the conveyor and fixed by means of sliding shafts on the drive shafts, and KPA is shaped guides. Figure 1 shows the diagram of the device; Fig. 2 is a schematic diagram of the implementation and installation of guides for removing radio components; figure 3 - diagram of the upper suspension of the conveyor with a sliding mandrel; on. FIG. MA of the lower drive shafts of the conveyor with sliding mandrels; Fig. 5 is a schematic of the conveyor dies. The device contains a heating chamber 1 with electric heaters 2 and a conveyor 3 with combs, in which fixed fixed guides 5 and 6 are installed for outputs of radio components 7, upper guide stars, daughters 8 and lower driving sprockets 9, which are mounted on sleeves 10 and 11 , connected through fingers 12, nuts 13 with right-hand thread and nuts And with left-hand thread with running screws 15 located in hollow shafts 16 and 17. Sprockets 8 are mounted on bushings 10 freely on bearings 18, and sprockets 9 are rigidly fixed on bushings 11 and through veneer ki 19 with shafts 17, which are kinematically connected to each other and the device drive is not shown. Hollow shafts 16 are mounted on a hinge chain 20 fixed to the camera body 1 using vertical spring thermal compensators 21 and horizontal thermal compensators 22. In the upper part of the camera 1, the guides are 5 seconds electric heaters 2 are fixed on common brackets 23. At the bottom of the drive shafts 17, the guides 2 are mounted on the sleeves 11 freely using bearings 2. 8 upper parts for mounting on the guides 5 in the walls of the chamber 1 are Yen windows 25 with plugs 26. To ensure readjustment of the device for cooling the internal volume of chamber 1, heads of screws 15 are led out to windows 27 of doors 28, on which scales are set 29. Rollers 30 and 31 are used for loading and unloading radio components 7. To increase the capacity of drying chamber 1 on the ridges of the conveyor 3, the sockets 32 for placing the axial leads of the radio components 7 are made coaxially with the pivot axis of the hinge chain 20, and to ensure the transition of the conveyor 3 on the curvilinear sections, the adjacent teeth 33 and 3 of the combs are separated us A device for heat treatment of radio components with axial leads works as follows. On the roller 30, the radio components 7, by their conclusions, are installed in the sockets 32 of the combs and transferred to the chamber 1, in which they are heat treated by the heat of the electric heaters 2. When the radio components 7 leave camera 1, they are unloaded under their own weight on roller 31 from conveyor 3 into the container installed underneath. The reliability of transporting radio components 7 to camera 1 is ensured by the fact that their axial leads are all the way. the sockets 32 and the slots of the guides 5 and 6, i.e. all the time in a closed state. Conveyor 3 is driven from lower sprockets 9. Upper sprockets 8 serve only to change the direction of conveyor 3.

When heated under the action of spring thermocompensators 21, the guides 5 and 6, in the places of their telescopic connection, are freely separated from each other, without affecting the passage of the outputs of the radio components 7 into them. Horizontal temperature compensation of the upper hinge chain 20 5 34. W

provided with thermal compensators 22.

When machining the radio components 7 OTHER LENGTH, an axial transducer is produced. moving the sprockets 8 and 9 with screws 15 through the windows 27 of the doors 28 of camera 1. When the screws 15 are rotating, the nuts 13 and 1 converge or diverge by moving fingers 12 in Tulles 10 and 11 with the radio components 7 mounted on them, sprockets 8 and 9 conveyor 3 with combs, bearings 18 and 2 with arcs of guides mounted on them (there are 6 of them and brackets 23 with guides 5 mounted on them and electric heaters 2.

Thus, without direct contact with the drying volume; without violating its temperature regime, it is possible to reconfigure the entire device (transport and heating systems).

During preventive maintenance or cleaning of the guides 5, the latter are removed through the windows 25 without disassembling the conveyor 3 //
