Description

Technical Field

[0001] The present invention relates to the technical field of LEDs, and particularly to a soldering structure for LED lamp beads. Background Art

[0002] LED is fully known as a semiconductor light-emitting diode, which has the advantages of low power consumption, high brightness, bright colors, anti-vibration, long life, cold light source, etc. Therefore, LEDs are becoming more and more common in our daily life. The basic structure of an LED is a semiconductor material chip that emits light when an electric current is applied. It is cured to a bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver wires or gold wires. Then, it is sealed with epoxy resin around to protect the internal core wires. However, in order to improve the performance and antioxidant property of the circuit board of an LED energy-saving lamp, soldering treatment is often required.

[0003] A prior patent (application number 202110103296.X) discloses a soldering mechanism for LED lamp beads, which also mentions that the existing soldering equipment for the circuit board of an LED energy-saving lamp requires manual soldering operation using clips. The circuit board of the LED energy-saving lamp that enters the solder often has incomplete soldering. It often requires manual inspection again to determine whether the soldering is complete, and then decide whether to perform the soldering operation again. An LED energy-saving lamp circuit board may require two or more soldering operations, and the soldering operation is time-consuming and laborious. At the same time, after soldering the LED lamp bead circuit board in the above patent, it is necessary to wait for the solder on it to dry naturally, which not only wastes time but also affects the soldering efficiency of the device. In addition, when the LED lamp bead circuit board is immersed in the solder for soldering, the temperature of the solder cannot be well controlled, and the solder is not well stirred, resulting in a general soldering effect of the LED lamp bead circuit board, and even multiple soldering operations may be required. To sum up, the existing soldering structure for LED lamp bead circuit boards also has the following problems:

[0004] 1. The existing soldering equipment for the circuit board of an LED energy-saving lamp requires manual soldering operation using clips. The circuit board of the LED energy-saving lamp that enters the solder is not only incompletely soldered, but also manual soldering is time-consuming and laborious; 2. After soldering the circuit board of an LED energy-saving lamp, it is necessary to wait for the solder on it to dry naturally, which not only wastes time but also affects the soldering efficiency of the device; 3. The temperature of the solder cannot be well controlled when soldering the circuit board of an LED energy-saving lamp, and the solder is not well stirred, resulting in a general soldering effect of the LED lamp bead circuit board. Therefore, we propose a soldering structure for LED lamp beads. Summary of the Invention

[0005] The main object of the present invention is to provide a tinning structure for LED lamp beads, which can effectively solve the problems that in the existing tinning equipment for the circuit board of LED energy-saving lamps, manual use of clips is required for tinning operation. The circuit board of the LED energy-saving lamp entering the tin liquid not only has incomplete tinning, but also manual tinning is time-consuming and laborious. After the circuit board of the LED energy-saving lamp is tinned, it is necessary to wait for the tin liquid on it to dry naturally, which not only wastes time but also affects the tinning efficiency of the device. When the circuit board of the LED energy-saving lamp is tinned, the temperature of the tin liquid cannot be well controlled, and at the same time, the tin liquid is not well stirred, resulting in a general tinning effect of the LED lamp bead circuit board.

Then, the piston rod of the output end is driven to expand and contract by the second hydraulic cylinder, driving the clamping plate and a plurality of clamping columns thereon downward. At this time, the clamping columns penetrate into the lamp bead slots, pressing the leads of the LED lamp beads into the second springs to complete the fixation of the LED lamp beads.

[0009] Preferably, the drying device includes an installation box body and an L-shaped mounting seat. A first heater is installed at the lower end of the installation box body, and an air outlet is installed in the middle of the front end of the installation box body. There are two L-shaped mounting seats. A set of mounting screws are installed at the front ends of both L-shaped mounting seats. Air blowers are installed at the upper ends of both L-shaped mounting seats. The two L-shaped mounting seats are respectively installed at the left and right parts of the rear end of the installation box body, and the installation box body is installed in the middle of the rear end of the support plate.

The motor drives the rotating shaft, and the stirring blades on the rotating shaft stir the tin liquid in the tin liquid box body, so that the LED lamp beads are fully mixed with the tin liquid for soldering.

[0012] Preferably, the pushing device includes a third hydraulic cylinder. A fixed seat is installed at the rear end of the third hydraulic cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By clamping a number of lamp bead grooves formed on the clamping seat of the soldering device, the device can clamp and solder multiple LED lamp beads at one time. Moreover, the clamping slots on the clamping seat are aligned with the first springs on the inner wall of the clamping frame, so that the clamping seat can be quickly clamped between the left inner wall and the right inner wall of the clamping frame, facilitating the placement or removal of the LED lamp beads. Then, the piston rod at the output end of the second hydraulic cylinder is driven to expand and contract, driving the clamping plate and several clamping columns thereon downward. At this time, the clamping columns penetrate into the lamp bead grooves, pressing the leads of the LED lamp beads into the second springs to complete the fixation of the LED lamp beads. Moreover, when soldering the LED lamp beads, the stirred solder drives the second springs, and the second springs generate a certain amount of shaking, so that the LED lamp beads have a certain shaking amplitude in the solder, thereby improving the soldering effect.

[0018] 2. After the LED lamp beads are clamped, the pushing device is used to push the fixed seat to slide in the chute, driving the first hydraulic cylinder to move above the solder tank. At this time, the first hydraulic cylinder pushes the clamping and soldering device into the solder tank for soldering. At this time, the motor on the stirring device drives the rotating shaft, and the stirring blades on the rotating shaft stir the solder in the solder tank, enabling the LED lamp beads to be fully mixed with the solder for soldering. Moreover, the temperature sensor on the temperature measuring and heating device detects the temperature in the solder tank, and the controller controls the second heater to heat, so that the solder can be maintained at a suitable soldering temperature, further improving the soldering effect of the LED lamp beads.

[0019] 3. When the soldering of the LED lamp beads is completed, the first hydraulic cylinder drives the clamping and soldering device to move in front of the air outlet of the drying device. At this time, the second hydraulic cylinder drives the clamping plate to contract, releasing the fixation of the LED lamp beads. Then, the first heater heats the air in the installation box, and the air is blown onto the LED lamp beads from the air outlet by the fan for rapid drying. Then, the pushing device drives the clamping and soldering device to move forward. At this time, the operator removes the clamping seat, places a new clamping seat and LED lamp beads for soldering. The device is simple to operate and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
