Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and in particular to a bowl-basket combination welding system and a welding method. Background Art

[0002] Currently, bowl basket racks on the market are usually composed of horizontal bars and vertical bars welded together. Therefore, the bottom net and four side nets need to be welded separately during the production process of the bowl basket. The existing technology lacks special equipment that can automatically weld the bowl basket, which makes welding inconvenient, has a low degree of automation, high labor costs, and low production efficiency.

[0003] CN201710605027.7 discloses an automatic mold-changing mobile spot welding device, including a medium-frequency inverter welding device, an aluminum bracket, an X-travel mechanism, a Y-travel mechanism, a Z transmission mechanism, a welding trolley, a double-layer mold turnover mechanism, a locking mechanism, and a demolding mechanism: a medium-frequency inverter welding device; the medium-frequency inverter welding device includes a welding bracket, a medium-frequency inverter welding power supply, an upper copper strip, an upper cylinder, a lower cylinder, and a control box; a medium-frequency inverter welding power supply is fixed on one side of the welding bracket; an upper cylinder is provided on one side of the welding bracket, and is connected to the upper copper strip on one side of the upper cylinder; a control box is welded on the top of the welding bracket; an aluminum bracket; the aluminum bracket includes an aluminum frame, a skirting, a mold pressing block, and a mold limit block. While this invention can automatically weld the bottom mesh of a basket, simplifying operations, reducing the number of workers and labor intensity, saving manufacturing costs, and significantly improving production efficiency, it cannot weld the side mesh of the basket, nor can it weld the entire basket. Furthermore, due to the numerous joints in the bottom mesh, many welding points are required, while this invention can only weld individual welding points one by one, resulting in relatively low production efficiency and failing to meet production capacity requirements. Furthermore, the welding carriage with the mold still needs to be manually pushed and pulled, which is not only inconvenient but also poses a safety hazard. Summary of the Invention

[0063] Reference Figure 1-5 and 17. One embodiment of the present invention provides a bowl and basket combined welding system, comprising: two bottom mesh welding devices A and four side mesh welding devices B, wherein the four side mesh welding devices B are sequentially distributed from one end to the other, and the two bottom mesh welding devices A are located upstream of the four side mesh welding devices B;

[0064] The bottom mesh welding device A includes: a first main frame A1 and a welding carriage A3 with a bottom mesh mold A2. The first main frame A1 is sequentially provided with a loading and unloading station A4, a turnover station A5, and a welding station A6 from one end to the other. The welding carriage A3 can slide back and forth between the loading and unloading station A4, the turnover station A5, and the welding station A6. The first main frame A1 is located above the loading and unloading station A4 and is provided with a push-pull die mechanism A7 for driving the welding carriage A3 to slide. The turnover station A5 is provided with a double-layer turnover mechanism A8, and welding station lifting mechanisms A9 for lifting and lowering welding station A6 are provided on both sides of welding station A6. The first main frame A1 is located in the middle and lower part of welding station A6 and is provided with a bottom mesh lower electrode plate A12. The first main frame A1 is located above welding station A6 and is provided with a push-pull die mechanism A7 and a four-head mobile welding mechanism A10. The first main frame A1 is located below the loading and unloading station A4 and is provided with a bottom mesh ejection mechanism.

[0065] The side mesh welding device includes: a welding table B1 and a second main frame B2. The second main frame B2 is fixed to one side of the welding table B1. A turntable B3 driven by a rotating motor is rotatably connected above the welding table B1. At least two welding ports B5 for fixing the side mesh mold B4 are evenly distributed above the turntable B3. A side mesh lower electrode plate B6 driven to rise and fall by an electrode lifting cylinder B13 is provided below the welding table B1 near the second main frame B2. A side mesh ejection mechanism is provided below the welding table B1 away from the second main frame B2. The turntable B3 can be rotated until one of the welding ports B5 is located directly above the side mesh lower electrode plate B6 or the side mesh ejection mechanism. The side mesh lower electrode plate B6 is directly opposite to the welding port B5. The second main frame B2 is provided with a spot welding mechanism.

[0066] Among the four side mesh welding devices B, the spot welding mechanism of the second side mesh welding device B from upstream to downstream is a single-head spot welding mechanism, and the spot welding mechanisms of the remaining three side mesh welding devices B are double-head spot welding mechanisms.

[0067] In the above technical solution, by providing two bottom mesh welding devices A and four side mesh welding devices B, the bottom mesh and side mesh of the bowl basket can be automatically welded, achieving high production efficiency. Furthermore, due to the different welding points between the bottom mesh and each side mesh, the two bottom mesh welding devices A utilize a four-head movable welding mechanism A10. The spot welding structure of the second of the four side mesh welding devices B is a single-head spot welding mechanism, while the spot welding mechanisms of the remaining three side mesh welding devices B are double-head spot welding mechanisms. This allows the bowl basket combined welding system to maintain essentially consistent welding times for the bottom mesh, front side mesh, rear side mesh, left side mesh, and right side mesh of each pair of bowl baskets, thus avoiding material accumulation or insufficient supply during production. Compared to traditional flat mesh spot welding followed by stretching, bending, and correction, the present invention allows for direct spot welding of the bent horizontal and vertical bars without the need for correction, saving both process steps and manpower, and avoiding the situation where stretching and bending after spot welding can cause loose welds.

The push-pull mold mechanism A7 of the loading and unloading station A4 pushes the welding trolley A3 with the next bowl basket to one layer of the double-layer turnover mechanism A8 of the turnover station A5, and the double-layer turnover mechanism A7 descends or ascends. After the bottom net welding is completed, the welding position lifting mechanism A9 ascends and resets. The push-pull mold mechanism A7 of the welding station A6 pushes the welding trolley A3 with the welded bowl basket to the other layer of the double-layer turnover mechanism A8. The push-pull mold mechanism A7 of the loading and unloading station A4 pulls the welding trolley A3 with the welded bowl basket of the double-layer turnover mechanism A8 to the loading and unloading station A4. The bottom net ejection mechanism ejects the welded bowl basket from the mold A2. At the same time, the double-layer turnover mechanism ascends or descends. The push-pull mold mechanism A9 of the welding station A6 pulls the welding trolley A3 with the next bowl basket to the welding position lifting mechanism A9 of the welding station A6, and the cycle continues.

[0069] When welding the side mesh of the bowl basket: place the front side mesh of the bowl basket welded by the bottom mesh welding device A on the side mesh mold B4 of the turntable B3 of the first side mesh welding device B; the turntable B3 rotates the side mesh mold B4 with the bowl basket to the top of the side mesh lower electrode plate B6; the electrode lifting cylinder B13 drives the side mesh lower electrode plate B6 to rise to the bottom of the side mesh mold B4, and the double-head spot welding mechanism cooperates with the side mesh lower electrode plate B6 to weld the front side mesh of the bowl basket. At the same time, place the front side mesh of the next bowl basket on the other side mesh mold B4 on the turntable B3; after the front side mesh is welded, the motor lifts The lowering cylinder B13 drives the side mesh lower electrode plate B6 to descend and reset, and the turntable B3 rotates the side mesh mold B4 with the welded bowl basket to just above the side mesh ejection mechanism. At the same time, the side mesh mold B4 with the next bowl basket rotates to above the side mesh lower electrode plate B6; the side mesh ejection mechanism ejects the welded bowl basket from the side mesh mold B4, and at the same time, the double-head spot welding mechanism cooperates with the side mesh lower electrode plate B6 to weld the front side mesh of the next bowl basket, and this cycle continues; the rear side mesh, left side mesh and right side mesh of the bowl basket are placed in the second, third and fourth side mesh welding devices B in turn for welding, completing the bowl basket welding.

The sliding plate A701 is slidably connected to the loading and unloading station A4 or the welding station A6, and is driven by the push-pull power mechanisms on both sides. A locking pin is fixed at the end of the piston rod of the locking cylinder A702. Two locking sockets A301 corresponding to the locking pin are respectively provided on the front and rear sides of the sliding direction of the welding trolley A3. The push-pull power mechanism is a screw transmission structure or a sprocket belt transmission structure. Specifically, for example: when the push-pull power mechanism is a screw transmission structure, a transmission screw driven by a drive motor is respectively arranged on both sides of the loading and unloading station A4 or both sides of the welding station A6. The length direction of the transmission screw is the same as the sliding direction of the welding carriage A3, and the two ends of the sliding plate A701 are respectively matched and connected to the transmission screws on both sides; when the push-pull power mechanism is a sprocket belt transmission structure, a sprocket is rotatably installed at the front and rear ends on both sides of the loading and unloading station A4 or both sides of the welding station A6, and the sprockets on the same side are connected by a chain or chain belt transmission, one of the sprockets on the same side is driven by a drive motor, and the two ends of the sliding plate A701 are respectively fixedly connected to the chains or chain belts on both sides.

[0081] In the above technical solution, when it is necessary to push and pull the welding trolley A3, the push-pull power mechanisms on both sides slide the sliding plate A701 to the front or rear of the sliding direction of the welding trolley A3, and the piston rod of the locking cylinder A702 extends, driving the locking pin to be inserted into the locking socket A301, so that the welding trolley A3 is fixedly connected to the sliding plate A701, and the welding trolley A3 slides following the sliding plate A701. When the welding trolley A3 slides to the target position, the locking cylinder A702 drives the locking pin to retract, and the sliding plate A701 is separated from the welding trolley A3. The sliding plate A701 slides and resets under the drive of the push-pull power mechanism, thereby realizing the function of automatically pushing and pulling the welding trolley A3, and the structure is simple.

[0082] Reference Figure 19 In some embodiments, the welding position lifting mechanism A9 includes a lifting plate A901 and a welding lifting cylinder A902. The first main frame A1 is located on both sides of the welding station A6 and is respectively provided with lifting plates A901 that slide up and down. The welding lifting cylinder A902 is fixedly connected to the first main frame A1 and drives the lifting plate A901 to slide up and down. A guide bar A9011 is provided above the lifting plate A901, and a positioning block A9012 is provided on the inner side of the end of the guide bar A9011 away from the turnover station A5. The lifting plates A901 on both sides are used to lift the welding carriage A3 of the welding station A6. When the welding carriage A3 slides to the welding station A6, that is, the welding carriage A3 slides onto the lifting plates A901 on both sides, and the welding lifting gases A902 on both sides drive the lifting plates A901 to descend at the same time. The lifting plates A901 drive the welding carriage A3 to descend to the bottom electrode plate A12 of the bottom mesh, ensuring that the bottom mesh of the bowl basket on the bottom mesh mold A2 can contact the lower electrode of the bottom mesh electrode plate A12 for welding. After welding is completed, the welding lifting cylinder A902 drives the lifting plates A901 to reset, and the welding carriage A3 can be pushed to the turnover station A5 by the push-pull die mechanism A7; the guide bar A9011 plays a guiding role, and the positioning block A9012 plays a positioning role, ensuring that the welding carriage A3 can accurately slide to the welding station A6 for welding.

[0083] Specifically, a strong magnet is installed on the side of positioning block A9012 near turnover station A5, and a photoelectric switch 11 is installed on the end of guide bar A9011 away from turnover station A5. The strong magnet secures welding carriage A3, preventing it from slipping during the raising and lowering of lift plate A901, thus ensuring accurate welding. The photoelectric switch A11 detects welding carriage A3, ensuring that the push-pull die mechanism A7 of welding station A6 can accurately push and pull welding carriage A3 to welding station 6.

[0084] Reference Figure 20In some embodiments, the double-layer turnover mechanism A8 includes a double-layer turnover frame A801 ​​and a turnover cylinder A802. The double-layer turnover frame A801 ​​is installed on the first main frame A1 for sliding up and down. The turnover cylinder A802 is fixedly connected to the first main frame A1 and drives the double-layer turnover frame A801 ​​to slide up and down. The upper and lower ends of the double-layer turnover frame A801 ​​are respectively provided with rotary blocks A804 driven by the rotary block cylinder A803. The coordinated structure of the double-layer turnover rack A801 ​​and the turnover cylinder A802 plays the function of sliding up and down to switch turnover, ensuring that the welding trolley A3 that has finished welding and the welding trolley A3 that has just been loaded can pass through the turnover station A5 at an alternate position. It has a simple structure and stable operation. The coordinated structure of the rotary stop cylinder A803 and the rotary stop block A804 ensures that the welding trolley A3 can be firmly placed on the double-layer turnover rack A801, preventing the welding trolley A3 from separating from the double-layer turnover rack A801 ​​during the up and down sliding process.

[0085] Specifically, photoelectric switches A11 are provided at both ends of the upper and lower layers of the double-layer turnover rack A801. The photoelectric switches A11 are used to detect the welding carriage A3 sliding onto the double-layer turnover rack A801 ​​and whether the welding carriage A3 has completely slid into the double-layer turnover rack A801.
