[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Example, a product robot soldering equipment, structure reference Figure 1-7As shown, the system comprises a stand 1, mounted with a six-axis robot 2 and a pneumatic oscillating mechanism 4 located in front of the robot 2. The front end of the robot 2 is connected to a soldering gun 3. The pneumatic oscillating mechanism 4 is arranged to swing between the base and the stand 1. A flipping mechanism 5 is located on top of the pneumatic oscillating mechanism 4, with a product rotation fixture 6 mounted on top. The product to be welded is secured in the product rotation fixture 6 and can be rotated and adjusted using the pneumatic oscillating mechanism 4. The flipping mechanism 5 rotates the product to a certain angle, and the six-axis robot 2 and soldering gun 3 are used to weld the first side of the product. After welding one side, the flipping mechanism 5 flips the product, and the six-axis robot 2 and soldering gun 3 are used to weld the other side. The six-axis robot 2 controls the soldering gun 3's tip to follow a three-dimensional curve, corresponding to the weld trajectory of the product. The specific product implemented is the housing of a switch mechanism.

[0031] The pneumatic swing mechanism 4 includes a swing plate 45, the middle of which is hingedly connected to the cylinder shaft of a swing cylinder 41. Cylinder 41 is mounted on the bottom of a frame 1, which has a hole for the cylinder shaft to pass through. A support base 42 is provided on the frame 1 below the left portion of the swing plate 45. The lower right side of the swing plate 45 is pivotally connected to the frame 1 via a hinged base 43. In the initial state of the pneumatic swing mechanism 4, the cylinder 41 is retracted, and the left portion of the swing plate 45 rests on the support base 42. To adjust the product's position, the cylinder shaft of the cylinder 41 is extended, and the swing plate 45 rotates about the hinged base 43, adjusting the product's angular position, i.e., adjusting the product's tilt.

[0032] The hole is provided with a cylinder shaft dust cover 44 to prevent dust.

[0033] The tilting mechanism 5 comprises two bearing blocks 51 mounted on the top of the pneumatic swing mechanism 4. Each bearing block 51 has a rotating shaft. The outer end of the rotating shaft in the left bearing block 51 is connected to a pneumatic rotary joint 52, while the outer end of the rotating shaft in the right bearing block 51 is connected to a servo motor 53. The servo motor 53 and the pneumatic rotary joint 52 are each mounted on the top of the pneumatic swing mechanism 4 via a mounting block 55. A clamping fixture 54 is connected to the inner side of each of the two rotating shafts. By starting the servo motor 53, the pneumatic rotary joint 52 on the opposite side engages, and the clamping fixture 54 can be rotated to any angle within 360° via the bearing block 51 and the rotating shaft.

[0034] The clamping fixture 54 comprises clamping plates 541 connected to the rotating shaft. A concave base plate 542 is connected between the clamping plates 541. Locking cylinders 543 are positioned midway between the left and right sides of the base plate 542. The two locking cylinders 543 secure the product turnover fixture 6 between them. The clamping fixture 54 uses the two locking cylinders 543 to quickly lock the product turnover fixture 6, allowing it to rotate with the clamping fixture 54, thereby enabling product flipping. To replace the product turnover fixture 6, simply release the two locking cylinders 543 and remove it for replacement.

[0035] It should be noted that there are many sets of product turnover fixtures 6. During the operation, that is, when the equipment is welding the products in the product turnover fixture 6, a person manually removes and inspects the welded products from the previous product turnover fixture 6 outside the machine, and then clamps the next product to be welded. After the equipment has completed welding, repeat the above steps, remove the previous product turnover fixture 6 from the equipment, and reinstall the next product turnover fixture 6; repeat the above steps continuously to realize human-machine assembly line operation.

[0036] The product turnover fixture 6 is very important in the continuous operation process. Because the welding trajectory is set, multiple sets of fixtures need to maintain high consistency and accuracy to ensure that the product solder trajectory is accurate during the fixture exchange process. Otherwise, the welding head trajectory will deviate from the product weld, and the welding quality will be lost.

[0037] The two locking cylinders 543 release the product turnover fixture 6 to replace other fixtures to adapt to other products to be welded.

[0038] The product turnover fixture 6 comprises a concave main plate 61, on which is mounted an outer product fixing mold 62, an inner product fixing member 63 adjacent to the outer product fixing mold 62, and an end product fixing member 64 opposite the outer product fixing mold 62. Both the base plate 542 and main plate 61 are concavely configured, and the outer product fixing mold 62, the inner product fixing member 63, and the end product fixing member 64 clamp and secure the product from all sides, thus avoiding the welding position of the product on both sides, leaving sufficient space for the soldering gun 3.

[0039] A handle 67 is provided on each side of the main plate 61 to facilitate the removal and insertion of the product turnover fixture 6. To ensure the accuracy of the replacement of multiple sets of product turnover fixtures 6, positioning holes 68 are provided on the main plate 61, and positioning pins 544 are provided on the bottom plate 542. The positioning holes 68 and positioning pins 544 cooperate to achieve precise positioning of the product turnover fixture 6. After positioning, the product turnover fixture 6 can be locked by the locking cylinder 543.

[0040] The shape of the product's outer fixing mold 62 matches the outer shape of the product. The product's inner fixing member 63 and the product's end fixing member 64 each include a push rod lock 66 fixed to the main plate 61. The front end of the push rod of the push rod lock 66 is connected to a lock head 65. The end shape of the lock head 65 of the product's inner fixing member 63 matches the inner shape of the product; the end shape of the lock head 65 of the product's end fixing member 64 matches the end shape of the product. Each fixing member matches the product's outer shape, facilitating the product's securement from three directions and all four sides. To secure the product, first place the product in the product's outer fixing mold 62, then press the two push rod locks 66, which push the lock heads 65 out and secure the product.

[0041] The platform 1 is equipped with safety gratings 7 on both sides, casters at the bottom, and a smoke extraction system 8 at the rear. A smoke vent is provided on the top of the platform 1. The safety gratings 7 prevent access to the equipment during operation. The smoke extraction system 8, an automatic smoke and dust filtration system, prevents contamination of both the working environment and the atmosphere.

[0042] The stand 1 is also provided with a solder paste 9 and a metal brush tip cleaner 10. The tip will oxidize and adhere to dirt over time, and the operating software is designed with a timed automatic cleaning function; and after cleaning, it automatically removes the solder paste from the solder paste 9 before continuing to work.

[0043] It also includes a measurement and control box assembly 11, a human-machine operation panel 12 and an operation button 13 fixed on the stand 1; as well as conventional accessories such as a box and casters at the bottom of the stand 1 and a three-color light at the top.

[0044] The operation buttons 13 include a mode selection key. When the key is turned to the far left, the teach pendant is in remote mode, and the host can remotely control the robot. This is the normal operating mode of the equipment robot. If it is not in this mode, the host will alarm until the key is turned to this mode. When the key is turned to the middle, the teach pendant is in automatic mode, and the host cannot remotely control the robot. When the key is turned to the far right, the teach pendant is in teaching mode, and the host cannot remotely control the robot. This mode is the robot debugging mode. A start button is pressed in automatic mode to start the selected program. A pause button is pressed in automatic mode to pause the ongoing program step. An emergency stop button is pressed in any mode to urgently stop the current action. Operation buttons are used to operate all buttons of the robot. The human-machine operation panel 12 includes a main display touch screen, which displays all information of the robot and can be touched to set relevant parameters and write programs.

[0045] It should be noted that the innovation of the present invention does not involve the production of parts, and the above-mentioned accessories are all purchased from existing products. Preferably, the six-axis robot 2 adopts a device made by Japan Yaskawa, model YR-1-06VX7-A00; the smoking system 8 adopts a welding fume purifier, and its working principle is that through the suction of the fan, the welding smoke exhaust gas is sucked into the air inlet of the equipment through the dust hood. A flame arrester is provided at the air inlet of the equipment, and the sparks are retained by the flame arrester. The smoke gas enters the sedimentation chamber, and uses gravity and upward airflow to directly drop the coarse dust into the ash hopper. The fine smoke is captured on the outer surface of the filter element. After the clean gas is filtered and purified by the filter element, it flows into the clean room from the center of the filter element. The clean air is further purified by adsorption by the activated carbon filter and discharged through the air outlet after meeting the standards; the tin soldering gun 3 adopts that of Kuake Company, and is equipped with an automatic wire feeding mechanism on it to accurately control the feeding amount of the welding wire. The present invention does not involve programming and adjustment of the operating system, etc. The systems involved in operating various trajectories of welding on the measurement and control box assembly 11, the human-machine operation panel 12 and the operation button 13 are also existing, such as the six-axis robot with its own operating system. The overall control principle of the present invention refers to Figure 8 shown.

[0046] Through the implementation of the above device, the manual loading cycle is about 6 seconds, the robot welding single-sided is about 40 seconds, and double-sided is about 80 seconds (depending on the complexity of the welding path), the manual unloading cycle is about 6 seconds, and the total cycle for double-sided welding of a product is less than 100 seconds, which is extremely efficient.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and concept of the present invention, which should be covered by the protection scope of the present invention.
