Description

Technical Field

[0001] The utility model relates to the technical field of light emitting diode welding auxiliary devices, in particular to a light emitting diode secondary welding and silver glue reinforcement device. Background Art

[0002] During the manufacturing or repair of LED light-emitting diodes, a device or process step is used to add silver glue to the second solder joint (i.e., the LED pin solder joint) to strengthen the solder connection. By adding silver glue, the physical strength of the solder joint is enhanced to prevent the solder joint from loosening or falling off due to factors such as vibration and temperature changes. Silver glue, as a conductive adhesive, can ensure that the solder joint has good conductivity, thereby ensuring the normal operation of the LED. The reinforced solder joint can withstand greater current and temperature changes, thereby improving the stability and service life of the LED.

[0003] In the above-mentioned prior art, when reinforcing the LED pins, workers generally position the LEDs by hand. Since stability needs to be maintained after welding to ensure the solidification of the silver glue, the instability of manual operation will cause the silver glue at the pins to loosen, which not only cannot guarantee the reinforcement effect, but also easily causes the LED to shift during the reinforcement process, affecting both the conductive performance and the overall aesthetics. Therefore, it does not meet the existing needs. In this regard, we propose a LED double-soldering and silver glue reinforcement device. Utility Model Content

[0004] The purpose of the utility model is to provide a light-emitting diode second soldering and silver glue reinforcement device to solve the problem of loosening of the silver glue at the pins due to the instability of manual operation proposed in the above background technology.

[0005] The cam is secured to the chassis and has a second locking mechanism, the second locking mechanism being secured to the chassis at a location adjacent to the chassis, and the second locking mechanism being secured to the chassis at a location adjacent to the chassis.

[0006] Preferably, a fourth slide groove is provided on the inner side of the longitudinal displacement mechanism, the slider on the outer side of the vertical displacement mechanism extends to the inside of the fourth slide groove and slides with the fourth slide groove, and two first springs are installed between the slider of the vertical displacement mechanism and the fourth slide groove.

[0007] Preferably, an LED end mounting hole is provided inside the lateral displacement mechanism, and clamping blocks are installed on both sides of the LED end mounting hole. A sliding rod is provided at one end of the clamping block, and the sliding rod extends into the sliding groove inside the lateral displacement mechanism, and a third spring is fixedly installed between the sliding rod of the clamping block and the sliding groove of the lateral displacement mechanism.

[0008] Preferably, support plates are fixed on both sides of the bottom of the fixing frame, and a base is integrally formed at the lower end between the support plates.

[0009] Preferably, fixed plates are provided on both sides above the base, and the outer sides of the fixed plates are fixed to the support plates, and positioning plates are provided under the fixed plates, and a movable rod is slidably installed at the middle position of the upper end of the fixed plate, and the lower end of the movable rod is connected to the fixed plate, and a second spring is installed on the top end of the movable rod and the fixed plate bracket.

[0010] Preferably, the upper end of the clamping block is provided with a chamfer.

[0011] Preferably, a rubber pad is adhered and fixed to the inner wall of the clamping block.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a longitudinal displacement mechanism and a transverse displacement mechanism, which can be adjusted accordingly according to the interface position of the circuit board. During the longitudinal adjustment process, the inner side of the adjusting bolt does not contact the fixing frame, so the sliders on both sides of the longitudinal displacement mechanism can move freely inside the first slide groove and the second slide groove. After moving to the specified position, by rotating the adjusting bolt, the rotational motion is converted into linear motion under the friction cooperation with the slider at one end, so that the adjusting bolt is in close contact with the fixing frame, and the longitudinal displacement mechanism is fixed at this position. A plurality of arc-shaped spring pieces are provided on both sides of the transverse displacement mechanism, and the arc-shaped spring pieces are engaged with the sliders at the first slide groove and the second slide groove. In the arc-shaped slot of the third slide slot inside the vertical displacement mechanism, the stability of the lateral displacement mechanism at this position can be ensured in the absence of external force. During the adjustment process, the user applies force to the lateral displacement mechanism, and one side of the arc-shaped slot squeezes the arc-shaped spring piece, causing it to deform, allowing the lateral displacement mechanism to move laterally. After moving to the specified position, the arc-shaped spring piece resets and snaps into the inside of the arc-shaped slot again to ensure adjustment stability. The cooperation between the longitudinal displacement mechanism and the lateral displacement mechanism can make the pins of the light-emitting diode accurately align with the interface of the circuit board, ensuring the stability of the subsequent welding process in a straight posture.

[0014] 2. The utility model provides a fourth slide groove inside the longitudinal displacement mechanism, and a first spring is provided between the fourth slide groove and the vertical displacement mechanism. Under the support of the first spring, it can ensure that the slider of the vertical displacement mechanism is located at the lower end of the fourth slide groove. Under the working condition of this position, the pin of the light-emitting diode is located at the welding position of the circuit board interface, avoiding shaking during the welding process. When installing the light-emitting diode, the user needs to lift the vertical displacement mechanism to the upper position and pass the light-emitting diode through between the clamps until the clamps contact the outer shell of the light-emitting diode. At the same time, under the support of the third spring, it can not only adapt to light-emitting diodes of different specifications, but also effectively improve the fixing effect of the clamps on the light-emitting diodes. This structure further improves the flexibility of light-emitting diode welding and also improves the welding stability.

[0015] 3. The utility model fixes the circuit board by arranging fixing plates on both sides above the base. Before installation, the user pulls the movable rod to move the positioning plate to the upper position. Then the circuit board passes from under the fixing plate. After moving to the specified position, the user releases the movable rod. Under the reset action of the second spring, the positioning plate squeezes and fixes the edge of the circuit board, thereby ensuring the stability of the circuit board and the light-emitting diode welding.
