The device for placing the workpieces contains (see Fig. 2), on the fly 19 with a locking nest 20, two parallel stands 21 and 22, and in the stand 21 there are two recesses 23 and a quick release lever clamp 24 with a handle 25, and the stand 22 is made of two parts 26 and 27 pivotally connected by an axis 28 and a retainer 29 of vertical and horizontal positions of the upper part 27, which has a hole 30 with a trigger-type pressure device 31 equipped with a handle 32, an outlet 33 and a contact group 34. The chamber 19 is provided with grooves 35 (see .fig, 2 and fig.Z).

FIG. 3 shows the fork 36 of the manipulator 9, the mold 37 of the injection molding machine 14, guides 38 mounted on the injection molding machine 14, the heating element 39 of the electric boil and the cord 40 with the plug 41.

Figure 4 shows a retainer 42 of a device for mounting workpieces 18, made in the form of pins 43 mounted on a plate 44, a coding device 45 made in the form of a pneumatic cylinder 46 with a pusher 47, a decryption device code 48 made in the form of a contactless inductive sensor , a decoding device 49, made in the form of a wedge, a code memory 50, made in the form of a housing 51, comprising a spring-loaded cam 53 fixed on the axis 52, having two stable positions. The encoder 45, the decryption device code 48 and the decoding device 49 are located on the transport system. Code storage device 50 is located on the device for installing the blanks 18.

The installation works as follows.

The main part of the installation is a transport system consisting of (see Fig. 1) the upper 1 and lower 2 branches of the conveyor, which is in continuous motion due to the influence of the driving 3 and tension 4 stations. The conveyor moves around the positions of the workplaces freely installed devices for installing workpieces 18. At all positions of the workplaces, except for places equipped with injection molding machines 14, the devices are stopped and fixed by retainer 42 (see Fig.4) due to the lifting of the plate 44 and the approach of the pins 43 in the sockets for fixing 20 (see Fig. 2) pallet 19, while the conveyor continues to move under the devices 18 (see Fig. 1). After the operation, the command is sent to

unclamping the tool 18 and it moves to the next location of the assembly operations. The transition of the devices 18 from the upper branch 1 of the conveyor to the lower branch 2 and vice versa is carried out by the lowering elevator 6 and the elevator lifting 5. At the workplace 7 (see fig. 1), the worker installs the upper part 27 (see fig.2)

0 pillars 22 in a horizontal position, fixes it with a latch 29. Then the worker sets the heating element 39 of the electric boiler into the depressions 23 of the pillar 21, fixes and bases it with a quick-action clamp 24 with a handle 25. At the automated location 10 (see Fig. 1) manipulator The torus 9 takes the tubes from the vibro-hopper 11 and puts them on the ends of the heating element. At the mixed automatic-manual place 8, the worker inserts plug 41 (see fig. 3) of the electric cord 40 in the socket 33 (see figure 2), and puts the end of the cord 40 in the hole 30, presses the presser 31 such as the handle 32 and then inserts each of the two conductors of the end of the cord into the appropriate tube, worn on each of the two conductors of the ends of the heating element, by unlocking and withdrawing the top part 27 of the rack 22 to a vertical position and fixing it in this position with the lock 29. Then at the command of a worker manip The torus 9 crimps the tubes, thereby connecting

5 pins of the end of the cord and the pins of the ends of the heating element.

At automated sites 12, plastics are being filled into the junction. Fill cycle twice

Q exceeds the average cycle of other operations. There are two such jobs in the installation. In order to carry out the parallel operation of both injection molding machines 14 and to ensure the free passage of the fixtures 18 to the second machine, the grip of the manipulators 9 is designed as a plug 36 (see Fig. 3), which engages with the grooves 35 and pushes the fixture 18 along the guides 38 to the mold 37 of the injection molding machine. A coding device 45 is installed on the first injection molding machine (see Fig. 4). and before the second, a code 48 decryption device in order to prevent the electric plug from the first machine from entering the second machine. Therefore, the code from each code memory 50 is read by a code 48 decoder and flooded electric boilers are directed past the second injection molding machine to an automated control stand 15 (see Fig. 1), before which all devices 18 are decoded on a decoding device 49 (see Fig. 4 ).

When fixing the device 18 on the position of the control stand 15, the external contact group 16 comes into electrical contact with the contact group 34 (see FIG. 2) of the device 18 and the electrical dimensions of the electric booster are checked for function, breakdown, short circuit and etc. Coding device 45 (see Fig. 4) mounted on test stand 15. encodes devices 18 with rejected electric heaters. Then all the devices 18 arrive at the place 17 for removing finished products from the installation, where the worker removes the devices and places the finished products in one container and the defective in another. Fixtures 18 are decoded and returned to work station 7 along the lower branch 2 of the conveyor.

The control of the transport system and technological equipment is carried out by a control device (not shown) using signals from inductive proximity sensors installed on the transport system and technological equipment.

The advantages of the proposed automated installation for assembling electrical appliances consist in expanding its technological capabilities to provide assembly of electrical appliances from blanks that do not have fixed sizes, and increasing its productivity, which will allow using it for assembling the heating element of an electrocipulator with a cord.
