Description

Technical Field

[0001] This utility model relates to the field of electronic component welding technology, and in particular to a capacitor welding auxiliary mechanism. Background Technology

[0002] When soldering capacitors onto a circuit board, they are usually mounted vertically. However, the capacitor head is relatively heavy and is easily tipped over due to vibration, which can damage the solder pads. Therefore, it is necessary to apply glue between the bottom of the capacitor and the circuit board to reinforce it and provide support for the capacitor head.

[0003] The following problems exist with the installation of capacitors in the existing technology:

[0004] 1. The capacitor head needs to be held by hand for soldering and gluing. When operating alone, it is inconvenient to solder and glu with one hand.

[0005] 2. There is no fixed shape when applying glue, which can easily result in applying too little or too much glue, potentially leading to glue waste, or uneven glue application that fails to provide effective support for the capacitor head.

[0006] Therefore, it is necessary to develop a capacitor welding auxiliary mechanism to solve the above problems. Utility Model Content

[0014] Second positioning mechanism;

[0015] The third positioning mechanism; both the second and third positioning mechanisms have a sealing plate at their lower ends. The sealing plate is formed into a semi-circular annular columnar structure. An injection hole is opened on the side wall of one sealing plate. The inner diameter of the sealing plate is slightly larger than the outer diameter of the capacitor head.

[0055] Working principle: During operation, the clamping plates 15 of the first clamping mechanism 3 and the second clamping mechanism 4 are moved separately. The first horn part 12 is twisted by hand, which drives the first screw 13 to rotate. The first screw 13 drives the rotating part 17 to rotate. The rotating part 17 pushes the clamping plate 15 forward or backward in the first rotating cavity 16 until the soft pads 18 of the first clamping mechanism 3 and the second clamping mechanism 4 press against the opposite sides of the circuit board. At this time, the position where the capacitor 28 needs to be installed is determined (multiple capacitors 28 are generally installed). First, the lateral position where the capacitor 28 needs to be installed is determined. Then, after the longitudinal guide plate 6 is slid into place, it is twisted by hand. When the second horn portion 19 is moved, it drives the second screw 20 to rotate. The second screw 20 then drives the first limiting plate 21 to move forward and press against the side wall of the transverse guide plate 1, thus fixing the relative position of the transverse guide plate 1 and the longitudinal guide plate 6. Then, the capacitor 28 is placed at a specific position in the longitudinal direction. The fourth positioning mechanism 10 and the fifth positioning mechanism 11 slide along the longitudinal groove 7 to clamp the capacitor 28. After the fourth positioning mechanism 10 and the fifth positioning mechanism 11 move to the specific position, the third horn portion 26 is twisted by hand, which drives the third screw 25 to rotate. The third screw 25 is screwed into the third screw hole 24. After rod 25 moves the second limiting plate 27 forward and it comes into contact with the side wall of the longitudinal guide plate 6, the position of the positioning plate 37 is fixed, and the head of the capacitor 28 is stably clamped. Similarly, the second positioning mechanism 8 and the third positioning mechanism 9 slide along the longitudinal groove 7. After the second positioning mechanism 8 and the third positioning mechanism 9 move to the designated position, the fourth horn part 32 is twisted by hand. The fourth horn part 32 drives the fourth screw 31 to rotate. The fourth screw 31 is screwed into the fourth screw hole 30. The fourth screw 31 drives the third limiting plate 33 forward and it comes into contact with the side wall of the longitudinal guide plate 6, thus fixing the position of the second sliding member 29. The inclined plate 34 and sealing plate 35 below 29 are fixed, and a sealed space is finally formed between the lower end of the capacitor 28 head and the circuit board. Glue can be injected through the glue injection hole 36. After the glue sets, all locks can be removed and the next capacitor 28 can be installed. When the height of the already installed capacitor 28 affects the height of the next capacitor to be installed, the first clamping mechanism 3 and the second clamping mechanism 4 can be loosened and the positions of the second positioning mechanism 8, the fourth positioning mechanism 10, the fifth positioning mechanism 11 and the third positioning mechanism 9 can be adjusted to avoid the already installed capacitor 28. Then the first clamping mechanism 3 and the second clamping mechanism 4 can be fixed.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
