Description

Solder paste coating device for processing LED copper wire lamp

Technical Field

The utility model belongs to the technical field of the LED lamp processing technique and specifically relates to indicate a processing of LED copper line lamp is with tin cream coating device.

Background

An LED lamp is a solid-state semiconductor device capable of converting electrical energy into visible light, which can directly convert electricity into light. The LED generally comprises a circuit board and lamp beads welded on the circuit board, and in the production process of the LED, solder paste is coated on the circuit board through a material leaking plate with holes, then the lamp beads are installed on the positions coated with the solder paste, and the circuit board is heated to harden the solder paste, so that the welding of the lamp beads is realized.

When the existing LED tin brushing machine brushes tin paste, in order to ensure that the steel mesh can be filled with the tin paste, the addition amount of the tin paste is generally large. When the scraper moves, the excessive solder paste is extruded to overflow to the two sides of the scraper, and the overflowed solder paste is collected and recycled by the scraper manually. The improvement is needed, so we propose a solder paste coating device for processing the LED copper wire lamp.

Referring to fig. 1 to 4, a solder paste coating apparatus for processing an LED copper wire lamp includes a worktable 1. A pair of cylinders is arranged on the workbench 1, and a fixed platform 3 is fixedly arranged on a telescopic rod of each cylinder. The fixed station 3 is used for placing FPC (flexible printed circuit), the two sides of the fixed station 3 on the workbench 1 are also used for fixing supporting plates, and a certain distance is reserved between the supporting plates and the two sides of the fixed station 3. Install steel mesh 2 on two backup pads, it has a plurality of meshs to open on steel mesh 2, mesh and FPC welding point one-to-one, places at fixed station 3 when FPC, and the cylinder raises fixed station 3, makes FPC welding point align with steel mesh 2 meshs, when brushing tin cream, makes falling into that tin cream can be accurate on the mesh FPC welding point, the follow-up welding LED lamp of being convenient for. A lifting hydraulic cylinder is arranged on the supporting plate, and the top of the hydraulic cylinder is fixedly connected with a top plate 4. A solder paste brushing assembly 5 is installed on the top plate 4, the left and right movement of the solder paste brushing assembly 5 is driven by a lead screw and guided by a polished rod, the lead screw is connected with a motor, and the forward and backward rotation of the motor drives the solder paste brushing assembly 5 to move left and right. The brush solder paste assembly 5 includes a central solder paste reservoir 7 and scrapers 6 on either side of the solder paste reservoir 7. Wherein, the bottom of the solder paste box 7 is provided with solder paste discharging holes, and the scraper 6 is controlled by a cylinder and can move up and down. Specifically, when brushing tin cream subassembly 5 when moving left and brushing tin cream, left side scraper 6 packed up this moment, and scraper 6 on right side supports steel mesh 2 through cylinder down stretching out and drawing back, brushes the tin. When moving to the left side of steel mesh 2, brush tin cream subassembly 5 reverse movement, left side scraper 6 pushes down through the cylinder and offsets with steel mesh 2 this moment, and right side scraper 6 is packed up. The in-process that removes about this will have unnecessary tin cream to spill over from the both ends of scraper 6, glue on the lateral wall of steel mesh 2 and fixed station 3, in order to retrieve this tin cream that spills over, it is equipped with collection frame 8 to hug closely steel mesh 2 and fixed station 3 lateral wall, collect the both ends of frame 8 installation fixing at brush tin cream subassembly 5, it has collection mouth 9 to collect frame 8 and be close to steel mesh 2 side and open, the width of collecting mouth 9 is greater than the interval between two scrapers 6, both guarantee that no matter which scraper 6 removes the brush tin, the tin cream that overflows from the side all is located and collects in the mouth 9. In order to recycle the collected solder paste, a recovery port 10 is arranged at the bottom of the collection frame 8, and the recovery port 10 is communicated with the solder paste box 7 through a pipeline. When a certain amount of solder paste is collected in the collection frame 8, a recovery pump 11 on the duct sucks the solder paste back to the solder paste tank 7. In order to collect the frame 8 and have better receipts and scrape the tin cream, collect the top of frame 8 and exceed the top of steel mesh 2, and collect the mouth 9 both sides and form the inclined plane that has certain inclination with the steel mesh 2 lateral wall.

Scraper 6 produces wearing and tearing after using a period, influence the brush tin quality after wearing and tearing, for the convenience can adjust scraper 6, it has a plurality of vertical adjustment tanks 13 to open on scraper 6, scraper 6 passes through locking bolt 14 and compresses tightly strip 15 and installs on installation slat 12, installation slat 12 is fixed on the cylinder, top at installation slat 12 still is equipped with two adjusting bolt 16, loosen locking bolt 14 earlier during the regulation, 16 to 6 position control of scraper at rotatory adjusting bolt, screw up locking bolt 14 after adjusting.
