Abstract

The invention relates to the field of soldering, in particular to a device for applying solder by pressing, and can be used in automatic devices to prepare for the installation of integrated circuits with planar leads. The purpose of the invention is to expand the functionality of the device. The device contains blocks 1, mounted on the base 2 with the ability to move in the horizontal plane. Each unit 1 includes an upper plate 4 and a lower plate 5, connected via columns 6, which allows the upper plate 4 to move in a vertical plane. On the upper plate 4, the punch 7 is fixed so that it can move in the horizontal plane along the guide 8. Due to this, the joint contact length of the punch and die is changed. The soldering mechanism includes a slider, a solder supply head connected to it, a pusher, a stop mounted for movement and connected to the punch 7 through a finger 35. When the punch is displaced, the amount of movement of the slider feeding the solder which is placed in the slider channel automatically changes. The knife, mounted on the die, has a cavity for gripping the end of the solder, interacts with the slider through the pusher. The device allows to press-on the solder to the terminals of radio elements of any width and length and to perform a rearrangement on the press-on of solder to various sizes of radio elements. 1 hp ff, 4 ill.

The invention relates to soldering, in particular, to soldering devices by pressing, and can be used in automatic devices to prepare for the installation of integrated circuits with planar leads.

The aim of the invention is to expand the functionality of the device.

FIG. 1 shows the proposed device, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2 (solder feed head); in fig. 4 — node I in FIG. 2

The pressing device consists of two blocks 1 installed on the base 2 and having the possibility of moving in the horizontal plane with the help of a screw 3. Each block 1 includes the upper plate 4 and the lower plate 5 connected by means of columns 6, which ensures the movement of the upper plate 4 in a vertical plane. On the upper plate 4, the punch 7 is fixed so that it can move in the horizontal plane along the guide 8 under the influence of the screw 9 and is pressed to the upper plate 4 through the spring 10. On the inner 25 end surface of the punch 7 there is a knife 11, pressed in the lowermost position is spring 12. On the bottom plate 5, a matrix 13 is installed with a knife 14 fixed on it, being in a balanced state by means of springs 15 and 16. The knife 14 has a cavity 17 for gripping the end of the supplied solder, above which the cutting edge 18 is placed Cutting edge 18 in the initial state uravnoveschen- prefecture located adjacent leaching

rotating the screws 9. The punch 7 is displaced along the guide 8 and through the sleeve 36 and the finger 35 carries the movable stop 34. Due to this, the combined length 5 of the contact of the punch and the die is changed. It is this length that determines the length of the molded area of solder to the terminals of the inserted radio element. Thus, any processed radio element must be arranged relative to the plane of symmetry along the width, and along the length the end of the radio element must coincide with the cutting edge 19 of the matrix 13. The bar of solder wound on the roller 29 is loaded into the feed head 27. To this end, the support spring 32 is pressed, the bar is inserted into the gap between the spring 32 and the wheel 30, and introduced into the guide pipe 33 until the bar comes out of the length 33 2-3 mm. The solder is fed by moving the slide 26. When the feed head 27 moves, the ratchet wheel 30 is wedged by the dog 31 and solder is unwound from the roller 29. When approaching the matrix 13, it interacts with the pushrod 20. The dog 24 with its wedge surface interacts with the wedge 22 of the knife 14. The knife 14 moves upwards. The cavity 17 rises above the cutting edge 19 of the matrix 13. At this point, the end of the solder rod is introduced into the cavity 17, the pawl 24 is displaced and the knife 14 is lowered by the action of the spring 15 to its original position. Thus, the inserted end of the bar is soldered, bent, and pinched between the cutting edge 18 and the cavity 17. When the slide 26 moves in the reverse direction, the pawl 31 does not prepress

the cutting edge 19 belonging to the matrix rotates the wheel 30, which allows

13. In the matrix 13, the pusher 20 is placed in the extreme position provided by the force of the spring 21. The wedge surface 22 of the knife 14 is in its initial state with a gap relative to the wedge surface 23 of the pawl 24 pusher 20. The soldering mechanism 25 is placed on the bottom plate 5 and consists from the slider 26 mounted on the slider 26 of the feed head 27 supporting roles 40

take the slider 26 up to the stop 34, leaving the strip of the desired length in the tense state due to the resistance of the pair of spring 32 to the wheel 30. When the slider 26 returns, the pusher 20 under the influence of the spring 21 returns to its original position, the dog 24 also returns to its original position . After that, the processed radio element is introduced. I will act on the upper plates 4, register 28, coils 29 with solder. The head 27 5 mechanism moves them, is produced

The feed has a ratchet wheel 30 with a pawl 31, which allows the wheel 30 to roll to one side, a support spring 32 in contact with the wheel 30, a guide nipple 33. A soldering head 27 for installing the solder. When moving the punch 7 down the knife 11 cuts the solder from one side. When the punch 7 acts on the knife 14, the spring 16 is compressed, the knife 14 is lowered and cut on the slider 26 with the possibility of 50 SCHSY 18 cutting the solder with another

Due to this, the joint length of the contact of the punch and the die is changed. It is this length that determines the length of the molded area of solder to the terminals of the inserted radio element. Thus, any processed radio element must be arranged relative to the plane of symmetry along the width, and along the length the end of the radio element must coincide with the cutting edge 19 of the matrix 13. The bar of solder wound on the roller 29 is loaded into the feed head 27. To this end, the support spring 32 is pressed, the bar is inserted into the gap between the spring 32 and the wheel 30, and introduced into the guide pipe 33 until the bar comes out of the length 33 2-3 mm. The solder is fed by moving the slide 26. When the feed head 27 moves, the ratchet wheel 30 is wedged by the dog 31 and solder is unwound from the roller 29. When approaching the matrix 13, it interacts with the pushrod 20. The dog 24 with its wedge surface interacts with the wedge 22 of the knife 14. The knife 14 moves upwards. The cavity 17 rises above the cutting edge 19 of the matrix 13. At this point, the end of the solder rod is introduced into the cavity 17, the pawl 24 is displaced and the knife 14 is lowered by the action of the spring 15 to its original position. Thus, the inserted end of the bar is soldered, bent, and pinched between the cutting edge 18 and the cavity 17. When the slide 26 moves in the reverse direction, the pawl 31 does not prep

When the slider 26 returns, the pusher 20 under the influence of the spring 21 returns to its original position, the dog 24 also returns to its original position . After that, the processed radio element is introduced. I will act on the upper plates 4, the drive mechanism moves them, is produced

Pressing solder on the findings of the radio element. When moving the punch 7 down the knife 11 cuts the solder from one side. When the punch 7 is exposed to the knife 14, the spring 16 is compressed, the knife 14 is lowered and I cut the edge 18 and cuts the solder with another

12 and 16, the knives 11 and 14 are returned to their original position. The length of the guide nozzle 33 is such that after cutting the solder with a knife 11, the length of the solder rod protruding from it is equal to 2-3 mm. The pressing on the subsequent radio elements is similar to that described. A forming punch mounted on the top plate with the possibility of moving in a horizontal plane relative to the fixed matrix provides for a change in the joint length of the contact of the punch and the die. The solder pruning knives are mounted spring-loaded, one on the end of the punch and the other on the opposite end of the die, which provides the trimming of that portion of the solder that is within the joint length of the contact of the die and the die.
