Description

The invention relates to the automation of assembly work in the manufacture of electronic equipment, communications and control equipment, in particular the assembly of circuit boards with hinged mounting and printed circuit boards.

The purpose of the invention is quality improvement.

Figure 1 shows the kinematic diagram of the device; figure 2 - tape; FIG. 3 shows molded contact in the jaws of the forming matrix; FIG. Fig. 4 shows the contact at the time of installation and fastening on the board; Fig. 5 shows the tape feed mechanism.

The device is placed on the bracket of the fixed base 1 of the coordinate table 2 and consists of a contact cutting mechanism that contains a cutting punch 3 and a cutting matrix 4, a forming punch 5, and the forming matrix and the transfer and installation mechanism are made in the form of a four-position rotary floating drum 6 with movable forming jaws 7 with guides pa-.

8. Sponges on the drum are offset relative to each other by 90 °.

The contact holding mechanism is made in the form of a forming matrix 9, which is placed under the board 10. The contacts 11 are cut out of the tape 12. The mechanism is driven from the electric motor 13 via the gear pair 14 to the main shaft 15. From the main shaft, the cams 16-18 are fed tape one step, cutting, molding contact 11; using the cams 19 and the support bearings 20, lowering the drum 6 in the guides 21c, then returning it to its original state by the spring 22 and turning the drum 6 by 90 ° using the Maltese cross 23; The mechanism of step-by-step feeding of the tape is made in the form of a mantra pusher 24.

The device works as follows.

Claims (1)

From the electric motor 13, through the gear train 14, the movement is transmitted to the main shaft 15. When the shaft is rotated, the cam 16 through the ejector plunger 24 feeds the belt 12 one step. The cams 17 lower the cutting punch 3. which interacts with the cutting die 4, cuts the contact 11 from the tape 12 and presses it against the upper forming jaws 7 of the drum 6. After that, the cam 18, lowering the forming punch 5, forms the contact into the upper jaws. Next, the cams 19 lower through the supporting bearings 20 along the guides 21 of the drum b, which, by interconnecting the lower moving jaws with the die, inserts the previously molded contact ends into the board holes and fixes the molded contact on the board 10 by bending its ends. By means of the spring 22, the drum returns to its original position. The Maltese cross 23 rotates the drum 6 by 90 °, preparing it to receive and install the contact in the next cycle. The slide of the table together with the board is moved to the next position — the predetermined position — the cycle is repeated. The invention of the device for cutting, forming and installing contacts on the board, which contains a tape feed mechanism, a contact punching mechanism, a movable forming punch, forming a matrix in the form of a multi-position rotary drum, mounted for reciprocating movement, a mechanism for securing contacts in the board, and a cam drive, characterized in that, in order to improve the quality, the forming matrix is provided with spring-loaded movable jaws with guide grooves fitted with sequential interaction with the forming punch and the mechanism for securing the contacts, and the mechanisms for cutting pins, feeding the tape and the multi-position swivel drum are kinematically connected to each other and driven by cams. 12: G C3: 0 : C) a -f (Rig.
