Description

Technical Field

[0001] The invention relates to the technical field of electronic device production, and in particular to a fast pick-and-place spot welding device for electronic device production. Background Art

[0002] Electronic equipment is basically explained as electrical equipment composed of microelectronic devices. When processing electronic devices, spot welding devices are required. Compared with manual spot welding, automatic spot welding devices have better accuracy and faster processing efficiency. However, existing automatic electric welding devices require manual transmission of devices to the bottom of the welding head for processing. This manual transmission method is not safe enough and is prone to electric shock. It is also inconvenient to take the devices back and forth, which requires a lot of labor and has low work efficiency. In addition, the electric welder cannot adjust the arc and cannot be used for different types of devices.

[0003] In the prior art, the mounting parts are welded together by electric arc welding. The electronic device 801 and the nut 802 are made of metal material. The surface of the metal material is relatively smooth. When light is irradiated to the surface, part of the light will be reflected. When the laser is irradiated on the spot welding area of ​​the electronic device 801 and the nut 802, if the laser is reflected more, the spot welding area absorbs less laser, which in turn affects the spot welding effect of the spot welding area. Therefore, a quick pick-up and place spot welding device for electronic device production is proposed. Summary of the invention

The airbag expands and contacts the outer wall of the electronic device and the nut. At this time, the rubbing point contacts the spot welding area of ​​the electronic device and the nut; the rotating drive member d drives the rotating sleeve to rotate, driving the rubbing point to rub the spot welding area of ​​the electronic device and the nut, making the spot welding area rough, reducing the amount of laser reflection in the spot welding area, increasing the absorbed laser, and enhancing the spot welding effect of the spot welding area.

Similarly, the linear driving member b272 drives the piston in the compression shell 270 to move upward. At this time, the compression shell 270 is at normal pressure, and the electronic device 801 in the receiving groove 231 can be removed; like Fig. 9 and Fig.10 As shown, the loading unit 4 includes: a linear drive member e41, which is mounted on the annular frame 11; a moving frame 42, which is mounted on the output end of the linear drive member e41; a material transport trough 43, which is mounted on the moving frame 42; a material bin 44, which is mounted on the material transport trough 43; a material drop pipe 45, which is mounted on the material transport trough 43; a linear drive member f46, which is mounted on the moving frame 42; a push block 47, which is mounted on the output end of the linear drive member f46; and a material pressing assembly 48, which is mounted on the material bin 44.

The linear drive member f46 drives the push block 47 to move forward, and pushes the nuts 802 at the bottom of the material bin 44 along the material transport trough 43 into the drop tube 45. At this time, the bottom of the nut 802 rests on the limiting ball 486.

At this time, the nut 802 is pressed above the electronic device 801, and the position of the nut 802 corresponds to the positioning rod 25; In this embodiment, the linear drive member a264 drives the positioning rod 25 to move upward, and the rotary drive member b267 drives the gear d268 to rotate, driving the positioning rod 25 to rotate, and driving the top thread 251 of the positioning rod 25 to completely rotate into the nut 802; It should be noted that: if the thread 251 can be completely rotated into the nut 802, it proves that the thread in the nut 802 is not damaged, and the next process is entered; if the thread 251 cannot be completely rotated into the nut 802, it proves that the thread in the nut 802 is damaged. At this time, the nut 802 with damaged threads is placed on the top of the electronic device 801, and the clamping unit 2 continues to be transported forward. When the clamping unit 2 is transported to the end of the circular assembly line, the clamping unit 2 will be tilted at an angle, and the nut 802 with damaged threads will fall under the action of gravity (a collection box can be set below to collect the nut 802 with damaged threads).

[0031] In this embodiment, the clamping unit 2 continues to move forward until the electronic device 801 clamped by the clamping unit 2 moves to the bottom of the rotating sleeve 551, the linear drive member d54 drives the rotating sleeve 551 to move downward and sleeve the outer side of the nut 802, and the linear drive member a264 drives the positioning rod 25 to move upward, driving the nut 802 to rise and contact the top of the inner wall of the rotating sleeve 551 (the state is as shown in FIG. Fig.12 As shown), at this time, air is inflated into the airbag 552 through the hose 554, and the airbag 552 expands and contacts the outer wall of the electronic device 801 and the nut 802. At this time, the kneading point 553 contacts the spot welding area of ​​the electronic device 801 and the nut 802; The rotary drive member d53 drives the rotary sleeve 551 to rotate, driving the kneading point 553 to knead the spot welding area of ​​the electronic device 801 and the nut 802, so that the spot welding area becomes rough, the amount of laser reflection in the spot welding area is reduced, the laser absorption becomes more, and the spot welding effect of the spot welding area is enhanced; It should be noted that: due to the provision of the hose 554, the rotation of the rotating sleeve 551 driven by the rotating driving member d53 is N turns forward and then N turns reverse, to avoid the hose 554 being entangled due to continuous forward or reverse rotation, which affects the use of the equipment.

[0034] In this embodiment, the clamping unit 2 continues to move forward until the clamping unit 2 moves to the end of the annular assembly line, at which time the clamping unit 2 is in an inclined state (such as Fig.13 As shown, the rotary drive member h62 drives the rotary rod 63 to rotate, driving the swing rod 64 to swing to fit the top of the electronic device 801 clamped by the clamping unit 2. At this time, the injection nozzle 67 corresponds to the spot welding area of ​​the electronic device 801 and the nut 802 (as shown in FIG. Fig.14 As shown), the rotating driving member a262 drives the gear b263 to rotate, drives the rotating shaft 22 and the clamping block 23 to rotate, drives the electronic device 801 and the nut 802 in the receiving groove 231 to rotate synchronously, and the injection nozzle 67 injects the anti-transmitting agent into the spot welding area of ​​the electronic device 801 and the nut 802, and the anti-transmitting agent can improve the arc welding effect; In this embodiment, the permeability enhancer is stored in a storage box. The permeability enhancer in the storage box is injected into the liquid injection nozzle 67 through the liquid inlet pipe 69 by a pump. The liquid injection nozzle 67 injects the permeability enhancer into the spot welding area of ​​the electronic device 801 and the nut 802. The excess permeability enhancer flows into the flow groove 641 under the action of gravity, and then flows back to the storage box through the return pipe 71, thereby collecting and recycling the permeability enhancer and improving the efficiency of using the permeability enhancer.

[0035] It should be noted that: in the kneading process, the spot welding area is kneaded to make the spot welding area rough. The rough spot welding area can better absorb the transmittance enhancer. The transmittance enhancer is dark in color to absorb more laser and further enhance the arc welding effect.

[0036] Working steps Step 1, loading process a: The circular assembly line runs, driving the clamping unit 2 to transfer forward, the manipulator puts the electronic device 801 into the receiving groove 231 on the clamping block 23, and then adsorbs the electronic device 801 into the receiving groove 231 through negative pressure (to prevent the electronic device 801 from falling off under the action of gravity when transferred to the bottom), the clamping unit 2 clamps the electronic device 801, and the clamping unit 2 continues to transfer forward until the electronic device 801 moves to the bottom of the drop tube 45, the axis of the drop tube 45 coincides with the axis of the positioning rod 25, and the linear drive member e41 drives the drop tube 45 to move downward and contact the top of the electronic device 801; Step 2, loading process b: multiple groups of nuts 802 are placed in the material bin 44, and the nuts 802 at the bottom of the material bin 44 are located in the material transport trough 43. The linear drive member f46 drives the push block 47 to move forward, and pushes the nuts 802 at the bottom of the material bin 44 along the material transport trough 43 into the drop tube 45. At this time, the bottom of the nuts 802 rests on the limiting ball 486; The linear drive member c482 drives the extrusion rod 483 to move downward, and squeezes the nut 802 whose bottom rests on the limiting ball 486 into the bottom of the drop tube 45 (the elastic connecting member 485 is compressed). At this time, the nut 802 is pressed above the electronic device 801; Step 3, installation process: the linear drive member a264 drives the positioning rod 25 to move upward, the rotary drive member b267 drives the gear d268 to rotate, driving the positioning rod 25 to rotate, and driving the top thread 251 of the positioning rod 25 to completely rotate into the nut 802; It should be noted that: if the thread 251 can be completely rotated into the nut 802, it proves that the thread in the nut 802 is not damaged, and the next process is entered; if the thread 251 cannot be completely rotated into the nut 802, it proves that the thread in the nut 802 is damaged. At this time, the nut 802 with damaged threads is placed on the top of the electronic device 801, and the clamping unit 2 continues to be transported forward. When the clamping unit 2 is transported to the end of the circular assembly line, the clamping unit 2 will be tilted at an angle, and the nut 802 with damaged threads will fall under the action of gravity (a collection box can be set below to collect the nut 802 with damaged threads). Since it is a circular assembly line, the clamping unit 2 is re-transmitted until the electronic device 801 moves to the bottom of the drop tube 45 again, and the installation process is completed; Step 4, kneading process: the clamping unit 2 continues to move forward until the electronic device 801 clamped by the clamping unit 2 moves to the bottom of the rotating sleeve 551, the linear driving member d54 drives the rotating sleeve 551 to move downward and sleeve the outer side of the nut 802, and the linear driving member a264 drives the positioning rod 25 to move upward, driving the nut 802 to rise and contact the top of the inner wall of the rotating sleeve 551 (the state is as shown in FIG. Fig.12 As shown), at this time, air is inflated into the airbag 552 through the hose 554, and the airbag 552 expands and contacts the outer wall of the electronic device 801 and the nut 802. At this time, the kneading point 553 contacts the spot welding area of ​​the electronic device 801 and the nut 802; The rotary drive member d53 drives the rotary sleeve 551 to rotate, driving the kneading point 553 to knead the spot welding area of ​​the electronic device 801 and the nut 802, so that the spot welding area becomes rough, the amount of laser reflection in the spot welding area is reduced, the laser absorption becomes more, and the spot welding effect of the spot welding area is enhanced; Step 5: Transmitter application process: The clamping unit 2 continues to move forward until it moves to the end of the annular assembly line. At this time, the clamping unit 2 is in an inclined state (such as Fig.13 As shown, the rotary drive member h62 drives the rotary rod 63 to rotate, driving the swing rod 64 to swing to fit the top of the electronic device 801 clamped by the clamping unit 2. At this time, the injection nozzle 67 corresponds to the spot welding area of ​​the electronic device 801 and the nut 802 (as shown in FIG. Fig.14As shown), the rotating driving member a262 drives the gear b263 to rotate, drives the rotating shaft 22 and the clamping block 23 to rotate, drives the electronic device 801 and the nut 802 in the receiving groove 231 to rotate synchronously, and the injection nozzle 67 injects the anti-transmitting agent into the spot welding area of ​​the electronic device 801 and the nut 802, and the anti-transmitting agent can improve the arc welding effect; Step 6, arc welding process: the clamping unit 2 continues to be transferred forward to the spot welding station at the bottom of the annular frame 11, at this time, the electronic device 801 and the nut 802 on the clamping block 23 are facing downward, and the arc welding robot 7 drives the arc welding head 700 to align with the spot welding area of ​​the electronic device 801 and the nut 802; The rotating shaft 22 is driven to rotate, driving the electronic device 801 and the nut 802 in the receiving groove 231 to rotate, and the arc welding head 700 emits laser to perform circular spot welding on the spot welding area of ​​the electronic device 801 and the nut 802; Step seven, blanking process: the clamping unit 2 is transferred to the top of the conveyor belt 13, and the linear drive component a264 drives the positioning rod 25 to move downward, driving the positioning rod 25 to rotate, driving the top thread 251 of the positioning rod 25 to rotate away from the nut 802, and the negative pressure hole 232 returns to normal pressure. Under the action of gravity, the electronic device 801 and the nut 802 are spot-welded and the installation parts fall onto the conveyor belt 13.
