[0034] Embodiment 1: During welding, the rotation control component 16 is started to drive the assembly frame 7 to rotate, and a group of positioning grooves 8 are kept vertically above. At this time, the No. 2 connecting air channel 21 in the assembly frame 7 is located above the No. 1 air hole 3 and is connected to the No. 1 air hole 3. The main board to be welded is inserted along the top of the positioning groove 8. At the same time, the reversing component 13 and the air supply part 17 are started, so that the air supply part 17 inputs the pressurized air into the distribution chamber 2, and the pressurized air is input into the No. 1 valve 131 through the air inlet end of the No. 1 valve 131 in the distribution chamber 2. The No. 1 valve 131 is actuated and connected to the No. 2 pipe 133, so that the pressurized air is input into the No. 2 air hole 4, and the connecting part connected through the corresponding position The pressure air is input into the rotating connecting component 15 through the hole 154, and after entering the corresponding connecting frame 151, the pressurized air is input into the elastic airbag 11 through the No. 1 connecting air channel 10. The elastic airbag 11 is inflated and expands, and wraps and clamps the motherboard to be welded from both sides. Then the No. 1 valve 131 is actuated to switch the ventilation direction, so that the pressurized air entering the No. 1 valve 131 is input into the No. 1 air hole 3 through the No. 1 pipe 132, and then the pressurized air is input into the sleeve cavity 14 through the No. 2 connecting air channel 21 above the No. 1 air hole 3, pushing the movable plug rods 124 on both sides to move, the spring 123 is compressed, and the clamping frames 121 on both sides are close to each other and clamp the motherboard to be welded, completing the rapid positioning and fixing. The rotation control component 16 is then started, and the rotation control component 16 is actuated and drives the assembly frame 7 to rotate, so that the positioning component 12 with the motherboard positioned is rotated 90° and remains horizontal. During the rotation process, the connecting hole 154 and the second connecting airway 21 are both sealed by the outer side of the fixed cylinder 1 to maintain stable clamping and positioning. The moving end and the welding end in the welding part 20 are started to realize the motherboard welding. During welding, the adjacent positioning grooves 8 are in a vertical state, and the next group of motherboards can be socketed and automatically positioned. As the motherboard welding on the horizontal side is completed, the welding part 20 is pushed out, and the rotation control component 16 is started to drive the assembly frame 7 to rotate 90° again. The motherboard after welding is rotated. To the vertical bottom, the adjacent positioned main board is rotated from the vertical direction to the horizontal direction and the next round of welding is carried out, and the No. 2 valve 6 in the air outlet groove 5 is kept open, and the welded main board is rotated to the bottom, and its corresponding No. 2 connecting air channel 21 is connected with the inner end of the air outlet groove 5, and the internal input pressure air bypasses through the air outlet groove 5, the positioning component 12 is reset to cancel the clamping, and the corresponding connecting hole 154 in the rotating connecting component 15 is located below and is also connected with the air outlet groove 5 through the small hole at the bottom of the fixed tube 1, so as to release and empty the internal pressure air of the elastic airbag 11, cancel the elastic wrapping clamping, and the welded main board located below loses the clamping force and slides out automatically, completing the automatic discharge.

[0035] First, by utilizing the reversing effect of the reversing component 13, pressurized air is input into the elastic airbag 11 and the positioning component 12 respectively. On the one hand, the elastic airbag 11 that is expanded by ventilation is used to wrap and position the edge of the vertically inserted main board. On the other hand, the positioning component 12 that is pushed by ventilation and displaced on both sides is used to clamp and fix the vertically inserted main board, so that the vertically inserted main board is quickly positioned and fixed. The actual positioning and fixing before welding is simple, and the stability after fixing is good. By utilizing the rotating assembly frame 7, the vertically positioned main board is switched to a horizontal state while rotating 90° and cooperates with the welding part on the side to realize the welding work. In the welding process, the adjacent positioning grooves 8 switched by rotation can be used to quickly realize the positioning and fixing of the next group of main boards to be welded while welding one group of main boards. The actual continuous welding operation of the main board is simple, the continuous welding efficiency is high, the continuous processing welding efficiency is greatly improved, and the use effect is good.

[0036] In addition, by utilizing the No. 1 air hole 3 and the No. 2 air hole 4 at the top of the fixed cylinder 1 and cooperating with the air outlet groove 5 at the bottom, when the positioning groove in the assembly frame 7 is rotated to the upper side, the main board to be welded in the positioning groove 8 can be quickly positioned and fixed, and when it is rotated to the horizontal side, the positioning and clamping under stable pressure are maintained to maintain welding stability, and while continuing to rotate for the next round of welding and loading positioning, the corresponding connecting hole 154 in the rotating connecting component 15 rotated to the bottom and the corresponding No. 2 connecting air channel 21 at the bottom are connected to the air outlet groove 5, so that the previously introduced pressurized air can be discharged, the pressure can be automatically relieved, the clamping and positioning can be cancelled, and the main board can be automatically separated from the discharge by its own gravity, thereby actually realizing the continuous processing of loading, welding and automatic discharge, and the entire welding processing link has a high degree of automation, which greatly improves the production and processing efficiency.

[0037] Embodiment 2: For individual mainboards that require double-sided welding, when continuous welding is performed during the rotation process, keep the No. 2 valve 6 in the air outlet groove 5 closed, first make the rotation control component 16 rotate forward, and sequentially position and socket the four groups of mainboards from the top, and after multiple consecutive forward intermittent rotations, weld the front sides of the four groups of mainboards. Since the No. 2 valve 6 in the air outlet groove 5 is sealed, the mainboards always remain clamped and positioned during the rotation process. When the four mainboards inserted in a group of assembly frames 7 have completed single-sided welding, push the welding part 20, and move and rotate together with the adjustment component 19, and swing and rotate along the top of the track frame 18, so that the welding part 20 moves to the other side of the assembly frame 7, and at the same time start the rotation control component 16 and rotate in the opposite direction, so that the clamped and positioned mainboard rotates to the horizontal position on the other side, and the unwelded surface on the other side is just facing the welding part 20 whose position has changed, and keep intermittent rotation to achieve the reverse side welding of the four groups of mainboards and realize double-sided welding.

[0038] Firstly, by utilizing the rotation action of the assembly frame 7 again and cooperating with the assembly of the adjustment component 19 and the track frame 18, when double-sided welding is required, the air outlet groove 5 is closed, so that during the continuous rotation process, the mainboards positioned and fixed in each group of positioning grooves 8 are always kept stable. After completing the single-sided welding process of four consecutive groups of mainboards, by moving the welding part 20 to the other side of the assembly frame 7 and rotating the assembly frame 7 in the opposite direction, the unwelded surface of the mainboard in the assembly frame 7 is located below the welding part 20 when it is turned to horizontal, thereby performing welding on the other side of the mainboard. After all the double-sided welding processes in the assembly frame 7, the automatic discharge of the mainboard after double-sided welding can be realized again by opening the No. 2 valve 6. In fact, for some scenarios that require double-sided welding, there is no need to re-flip, position and clamp the mainboard, and the fast and continuous reverse welding operation can be completed. The actual switching operation is simple, the double-sided welding efficiency is high, and the use effect is good.

[0053] The working principle and use process of the present invention are as follows: during welding, the rotation control component 16 is started to drive the assembly frame 7 to rotate, and a group of positioning grooves 8 are kept vertically above. At this time, the No. 2 communicating air channel 21 in the assembly frame 7 is located above the No. 1 air hole 3 and is connected with the No. 1 air hole 3. The main board to be welded is inserted along the top of the positioning groove 8. At the same time, the reversing component 13 and the air supply part 17 are started, so that the air supply part 17 inputs the pressurized air into the distribution chamber 2, and the pressurized air is input into the No. 1 valve 131 through the air inlet end of the No. 1 valve 131 in the distribution chamber 2. The No. 1 valve 131 is actuated and connected with the No. 2 pipe 133, so that the pressurized air is input into the No. 2 air hole 4 and passes through the corresponding position. The connecting hole 154 connected to the mounting is input into the rotating connecting component 15, and after entering the corresponding connecting frame 151, the pressurized air is input into the elastic airbag 11 through the No. 1 connecting airway 10, and the elastic airbag 11 is inflated and expands, and wraps and clamps the motherboard to be welded from both sides, and then the No. 1 valve 131 is actuated to switch the ventilation direction, so that the pressurized air entering the No. 1 valve 131 is input into the No. 1 air hole 3 through the No. 1 pipe 132, and then the pressurized air is input into the sleeve cavity 14 through the No. 2 connecting airway 21 above the No. 1 air hole 3, pushing the movable plug rods 124 on both sides to move, the spring 123 is compressed, and the clamping frames 121 on both sides are close to each other and clamp the motherboard to be welded, completing the rapid welding. After positioning and fixing, the rotation control component 16 is then started. The rotation control component 16 is actuated and drives the assembly frame 7 to rotate, so that the positioning component 12 with the motherboard positioned thereon is rotated 90° and remains horizontal. During the rotation process, the connecting hole 154 and the second connecting airway 21 are both sealed by the outer side of the fixing tube 1 to maintain stable clamping and positioning. The moving end and the welding end in the welding portion 20 are started to realize the motherboard welding. During welding, the adjacent positioning grooves 8 are in a vertical state, so that the next group of motherboards can be socketed and automatically positioned. As the motherboard welding on the horizontal side is completed, the welding portion 20 is pushed out, and the rotation control component 16 is started to drive the assembly frame 7 to rotate 90° again. The motherboard after welding is rotated. Rotate to the vertical bottom, the adjacent positioned main board rotates from the vertical direction to the horizontal direction and performs the next round of welding, and keep the No. 2 valve 6 in the air outlet groove 5 open, rotate to the welded main board below, and its corresponding No. 2 connecting air channel 21 is connected with the inner end of the air outlet groove 5, and the internal input pressure air bypasses through the air outlet groove 5, the positioning component 12 is reset to cancel the clamping, and the corresponding connecting hole 154 in the rotating connecting component 15 is located below and is also connected with the air outlet groove 5 through the small hole at the bottom of the fixed tube 1, so as to realize the release and emptying of the pressure air inside the elastic airbag 11, cancel the elastic wrapping clamping, and the welded main board located below loses the clamping force and slides out automatically, completing the automatic discharge;For individual mainboards that need double-sided welding, when continuous welding is performed during the rotation process, the No. 2 valve 6 in the air outlet groove 5 is kept closed, and the rotation control component 16 is first rotated forward, and the four groups of mainboards are positioned and sleeved from the top in turn. After multiple consecutive forward intermittent rotations, the front sides of the four groups of mainboards are welded. Since the No. 2 valve 6 in the air outlet groove 5 is sealed, the mainboards are always clamped and positioned during the rotation process. When the four mainboards inserted in a set of assembly frames 7 are all completed with single-sided welding, the welding part 20 is pushed, and the adjustment component 19 is moved and rotated, and the welding part 20 is swung and rotated along the top of the track frame 18, so that the welding part 20 moves to the other side of the assembly frame 7, and the rotation control component 16 is started and rotated in the opposite direction, so that when the clamped and positioned mainboard is rotated to the horizontal position on the other side, the unwelded surface on the other side is just facing the welding part 20 whose position has changed, and the intermittent rotation is maintained to achieve the reverse side welding of the four groups of mainboards, and the double-sided welding process is achieved. ;
