In the specific implementation, substrate 72 is placed on conveyer belt 11 for the device, and first sensor 12 detects signal, from
And conveyer belt 11 is made to bring into operation, substrate 72 is conveyed to the right.Substrate 72 is in contact when moving right with rotating wheel 15, from
And be pressed downward rotating wheel 15, make rotating wheel 15 that cursor 14 be driven to rotate.Angle of rotation of the angle monitor device 16 to cursor 14
Degree measures, and the distance between 72 bottom surface of substrate and 10 bottom surface of clamping plate is calculated to calculate angle change, following
Inserting link in more preferable grade slab 72 be supported.It is connected with the first spring 18 between cursor 14 and fixed block 17, works as base
When plate 72 leaves 15 top of rotating wheel, cursor 14 is since the elastic reaction of the first spring 18 returns to original position, to continue under
One piece of substrate 72 measures.When substrate 72 is moved to inserting position, hydraulic cylinder 19 controls hydraulic stem 20 and extends, the first support plate 21
It drives supporting rod 22 to rise again, so that second spring 25 and the bottom surface of substrate 72 is in contact, and then substrate 72 is lifted off conveyer belt 11,
It supports to ensure the progress of inserting.Ensure that there are distances between 10 bottom surface of 72 upper surface of substrate and clamping plate, keep away simultaneously
Exempt from substrate 72 and withstand on clamping plate 10 to be pressurized and generate bending.It is connected with second spring between second support plate 24 and supporting rod 22
25, the second support plate 24 has cushioning effect when being contacted with 72 bottom surface of substrate, and dynamics is excessive and damage base when can avoid contact with
72 bottom surface of plate.First motor 28 controls the rotation of the first screw rod 29, to drive movable stand 31 to move in the longitudinal direction.Second electricity
Machine 35 drives driving chain 36 to move, and drives the first sliding block 33 to move in the horizontal direction using movable block 34, to adjust wave
The position of peak welding machine body 55 makes wave-soldering body 55 be directed at the location of feeding piece 8.Third motor 40 drives 41 turns of driving wheel
Dynamic, driving wheel 41 drives driven wheel 44 to rotate using driving belt 43, to drive the rotation of the second screw rod 42, controls the second sliding block
38 move on fixed block 37 so that suction nozzle 48 drops to suitable position.It is inhaled using the element that suction nozzle 48 provides feeding piece 8
It rises, recycles mobile mechanism 4 to take part and set first 5 and be moved to corresponding position on substrate 72, element is inserted on substrate 72
Pcb board is made.Element and substrate 72 are monitored using CCD image pick-up devices 54, is more accurately positioned and is installed.Pcb board
It is placed on conveyer belt 56, the first fixing groove 70 and the second fixing groove 71 is offered on the fixed part 69 in conveyer belt 56, is used for
The fixed fixture for loading pcb board ensures that welding section is exposed while pcb board is fixed.Pcb board is conveyed by conveyer belt 56,
When by second sensor 58, second sensor 58 receives signal, and follow up device is made to bring into operation.It second sensor 58 and helps
It is equipped with dust-extraction unit between solder flux nozzle 59, the dust of welding section can be removed, dust is avoided to influence the quality of welding.Pcb board
When reaching scaling powder 59 top of nozzle, scaling powder is sprayed by scaling powder nozzle 59, makes exposed pads surface, pad via and member
Device pin uniformly overlay very thin scaling powder is equipped with surface area between second sensor 58 and scaling powder nozzle 59
Computing module, to control the amount for the scaling powder that scaling powder nozzle 59 sprays.Utilize the first preheating mechanism 60, the second preheating mechanism
61 heats sent out carry out primary and secondary preheating, so that welding position is heated to wetting temperature, simultaneously as component temperature
Raising, avoid immerse fusion welding when by big thermal shock.When preheating, the solvent in scaling powder is evaporated, in this way
Gas is generated when can reduce welding；Rosin and activating agent start to decompose and activate in scaling powder, can remove pad, first device
The oxidation film and other pollutants of part end and pin surface, while playing protection metal surface and preventing high temperature reoxidation
Effect；So that pcb board and component is fully warmed-up, steep temperature rise when welding is avoided to generate thermal stress damage pcb board and component.
Secondary preheating can be such that temperature steps up so as to be uniformly heated.Heat is carried out using the heat that thermal compensation mechanism 62 is sent out
Compensation reduces the thermal shock in welding process.After pcb board enters scolding tin chamber 84, by electrodynamic pump 65 by the high temperature in solder pot 64
Liquid tin jet flow slides wave at first wave turbulent wave and the second popin.Turbulent wave flow velocity is fast, has preferable permeability to welding position,
Meanwhile the upward jet power of turbulent wave makes scaling powder gas smoothly exclude, and greatly reduces solder skip and vertical lack of fill
Defect.Smooth wave soldering tin flowing velocity is a little slower, can effectively remove the excessive scolding tin on terminal, so that all welding surfaces is soaked good
It is good, and can draw and bridge caused by turbulent wave and adequately be corrected.Nitrogen supply (NS) pipe 66 is during the welding process to scolding tin
Nitrogen is discharged in chamber 84, can effectively prevent the oxidation of welding section, it is ensured that the reliability of solder joint.The pcb board arrival for completing welding is cold
But on fan 67, the wind-force generated using cooling fan 67 cools down pcb plates, and pcb plate temperatures is made drastically to decline to improve
The vacuole and pad stripping problem that kupper solder eutectic generates when producing.The pcb plates after soldering are completed outside assembling station and LED light
Shell fits together, and is sent into ageing machine together and carries out burin-in process.After LED light is mounted on lamp holder 75, by air-introduced machine 79
Fresh air sucks, and introduces air-out chamber 81 by air feed chamber 80, then blow in LED light.After heating resistance wire 83 starts, air is carried out
Heating, makes that hot-air is made to blow in LED light, makes the temperature rise of LED light local environment.Start cooler 82, to air feed
Air in chamber 80 cools down, and to make cold wind blow in LED light, the temperature of LED light local environment is made to decline.To LED light
It is heated and is cooled down, to test the working condition of LED light under various circumstances.Using temperature monitoring 78 to ageing machine machine
Temperature in body 73 is detected, to be started to control cooler 82 or heating resistance wire 83 according to preset value.Profit
The environment in ageing machine body 73 is humidified with humidifier 76, to test the stability that LED light works under high humidity environment
And safety.The LED light for completing burn-in test is examined by color detection means, luminance detection device, appearance delection device respectively again
Light color, lamplight brightness and complete appearance degree are surveyed, cases and is stored up after being packed by automatic packaging machine by the LED light of test
It deposits.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
Those of ordinary skill for, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
