[0041] The discharge mechanism includes a rotating shaft 71. Two rotating shafts 71 are rotatably arranged in the shell 1 through bearings. A turntable 72 is installed at one end of the two rotating shafts 71 close to each other. Twenty discharge grooves 73 for placing the lead body 52 are evenly spaced on the curved surface of each turntable 72. Rubber bags 74 are embedded on both sides of each discharge groove 73. Overrunning clutches 75 are installed on the two rotating shafts 71. Intermittent gears 76 are installed on each overrunning clutch 75. A square frame 77 is slidably installed in the middle of the shell 1. The square frame 77 is connected to the two drive frames 63. Two vertical racks 78 are installed on the frame 77. The two vertical racks 78 are respectively located on one side of the two intermittent gears 76. After the vertical racks 78 move, they engage with the intermittent gears 76.

[0042] Twenty moving magnet columns 781 are evenly spaced on the side where the two turntables 72 are close to each other. Each moving magnet column 781 corresponds to each discharge trough 73 one by one. A fixed magnet column 782 is installed on both side walls of the hopper 4. The fixed magnet column 782 on the same side and the side where the twenty moving magnet columns 781 on the same side are close to each other have opposite magnetic properties.

A pushing frame 84 is installed on the sliding plate 62, and two pushing grooves are opened on the pushing frame 84. Each pushing groove consists of two vertical grooves and a crooked groove. The crooked groove is located between the two vertical grooves, and the two ends of the horizontal axis 82 are located in two of the vertical grooves of the pushing frame 84.

[0044] The pushing mechanism includes a pushing block 91. Twenty pushing blocks 91 are evenly spaced and slidingly arranged on each turntable 72. Each pushing block 91 is located in a corresponding discharge trough 73. A card slot 92 is provided on one side of each pushing block 91. A cylinder 93 is installed on each side of the shell 1. The two cylinders 93 are symmetrically arranged. A card block 94 is installed on each of the two telescopic rods, and the card block 94 is stuck in one of the corresponding card slots 92.

[0045] The hopper 4 and the turntable 72 are connected by a torsion spring 135 to the two sides of the swing frame 133. A pendulum gear 134 is installed at both ends of the flat shaft 132. A gear ring 136 is installed on the side close to each other of the two turntables 72. Twenty groups of gear blocks are evenly spaced on the gear ring 136. The gear blocks on the gear ring 136 rotate and engage with the pendulum gear 134 in turn. Two telescopic plates 137 are slidably arranged on both sides of the lower part of the hopper 4. Two straight grooves are provided on the two swing frames 133. The telescopic plates 137 on the same side are slidably connected to the straight grooves on the swing frames 133.

[0046] After the operator opens the two covers 2, he rotates the turntable 72 in turn and puts the lead body 52 into the discharge chute 73 in turn, and then closes the two covers 2. Under the elastic clamping action of the rubber bag 74, the lead body 52 can be initially limited and fixed to prevent the lead body 52 from being displaced during the subsequent rotation process. At the same time, the material of the lead body 52 is not adsorbed by the magnet. When the turntable 72 rotates, the twenty moving magnet columns 781 rotate synchronously. Under the magnetic force cooperation between the moving magnet column 781 and the fixed magnet column 782, the turntable 72 is stably limited, effectively preventing the turntable 72 from deflecting due to inertia, thereby improving the running stability and repeated positioning accuracy; then the operator puts an appropriate amount of component body 51 into the hopper 4, and the bottom component body 51 contacts the two telescopic plates 137 below. The operator controls the telescopic rods of the two electric push rods 61 to extend, and the telescopic rods drive the sliding plate 62, the drive frame 63, the square frame 77, and the vertical The gear 76 of the present invention is fixed on the cam 72, and the gear 77 of the present invention is fixed on the cam 72, so that the gear 77 of the present invention can be fixed on the cam 72, and the gear 77 of the present invention can be fixed on the cam 72, so that the gear 77 of the present invention can be fixed on the cam 72, and the gear 77 of the present invention can be fixed on the cam 72,When the ring gear 136 rotates eighteen degrees, a set of teeth on it engages with the pendulum gear 134 and then disengages, driving the pendulum gear 134, the flat shaft 132 and the swing frame 133 to swing rapidly. Under the elastic restoring action of the torsion spring 135, the swing frame 133 quickly returns to its initial position. When the swing frame 133 swings, the two upper telescopic plates 137 move away from each other, and at the same time, the two lower telescopic plates 137 move toward each other, so that the lowest component body 51 in the upper component stack is separated and falls onto the upper part of the two lower telescopic plates 137. When the swing frame 133 is reset, The two upper telescopic plates 137 move toward each other, and the two lower telescopic plates 137 move away from each other, completing the structural reset and clamping the new round of component bodies 51. The two upper telescopic plates 137 can continue to support the remaining component bodies 51, and the two lower telescopic plates 137 send the current component body 51 to between the correction frame 1 641 and the correction frame 2 642. As the driving frame 63 moves upward, under the guidance of the inclined slot on the driving frame 63, the two rollers 65 drive the correction frame 1 641 and the correction frame 2 642 to move toward each other, and the correction frame The two 642 linkage positioning frames 11 move synchronously to achieve accurate axial and radial correction of the component body 51. After the correction frame 1 641 and the correction frame 2 642 jointly clamp the component body 51, the positioning frame 11 is in the lower area of ​​the component body 51 and does not interfere with the subsequent welding operation. Then the operator controls the extension of the telescopic rod 2 of the two cylinders 93 to drive the two clamping blocks 94 to move toward each other. The two clamping blocks 94 drive the two pusher blocks 91 to move toward each other, so that the two pusher blocks 91 drive two of the lead bodies 52 to move toward each other. , precisely docking to the welding positions set on both sides of the component body 51, ensuring that the welding bonding area is maximized, improving welding strength and reliability; at this time, the straight groove on the driving frame 63 moves into the roller 65, and the crooked groove on the pushing frame 84 moves to the horizontal axis 82. The crooked groove drives the horizontal axis 82 to synchronously drive the slider 81 and the two welding guns 83 to move to both sides of the component body 51, so as to achieve precise alignment of the welding guns 83 with the docking areas of the two lead bodies 52. The two welding guns 83 complete the automatic welding of the two lead bodies 52 and the component body 51, improving welding consistency and efficiency;After welding is completed, the operator controls the telescopic rods 1 of the two electric push rods 61 to extend again, driving the sliding plate 62, the driving frame 63, the frame 77, the vertical rack 78 and the pushing frame 84 to move upward as a whole. The inclined groove on the driving frame 63 moves the correction frame 1 641 and the correction frame 2 642 away from each other under the guidance of the two rollers 65, so that the welded component body 51 is disengaged from the clamping mechanism and discharged. The upward movement of the vertical rack 78 continues to drive the intermittent gear 76 to rotate, and the overrunning clutch 75 limits its driving shaft 71 and the turntable 72 to rotate. Then the telescopic rod 1 is shortened again to drive the device to reset. The vertical rack 78 drives the intermittent gear 76 to rotate eighteen degrees again, driving the shaft 71, the turntable 72, the rubber bag 74, the push block 91, the gear ring 136 rotates synchronously with the lead body 52 by eighteen degrees and stops, completing the alignment of the next set of lead bodies 52 with the welding station. The fixed magnet column 782 again attracts a new set of moving magnet columns 781, ensuring accurate and reliable welding position each time. After the ring gear 136 rotates eighteen degrees, the tooth block again engages and disengages with the swing gear 134, driving the swing frame 133 to swing and reset. The upper and lower telescopic plates 137 open and close in sequence, achieving the transfer and blanking of the next component body 51. The vertical slot on the push frame 84 moves to the horizontal shaft 82. The vertical slot drives the horizontal shaft 82, the slide 81, and the welding gun 83 away from the welding area and resets, preparing for the next round of welding. The device continuously cycles, achieving continuous and efficient welding of the component body 51 and the lead body 52.

[0047] Example 2: Based on Example 1, Figures 9-11 As shown, it also includes an expansion mechanism arranged on the turntable 72, the rubber bag 74 and the pusher block 91. The expansion mechanism is used to correct the lead body 52. ​​Forty cylinders 101 are provided on the side of the two turntables 72 away from each other. Each cylinder 101 is connected to each rubber bag 74 respectively. A piston rod 102 is slidably provided in each cylinder 101. A connecting rod 103 is installed on each pusher block 91. The two piston rods 102 on both sides of each pusher block 91 are connected to the connecting rod 103 on the pusher block 91.

[0048] When the two pusher blocks 91 move toward each other, they simultaneously drive the two connecting rods 103 to move toward each other. The two connecting rods 103 drive the piston rod 102 forward, pushing the gas stored in the cylinder 101 into the rubber bag 74. After being pressurized, the rubber bag 74 expands to form a controllable clamping effect, and performs precise position correction on the lead body 52, so that it fits more closely with the side wall of the component body 51, the contact surface of the welding is sufficient, and the welding stability and the quality of the weld are improved; when the two pusher blocks 91 move away from each other, they simultaneously drive the two connecting rods 103 to move in the opposite direction, and the piston rod 102 drives the gas in the rubber bag 74 to be drawn back into the cylinder 101. The rubber bag 74 contracts and releases the clamping force, thereby releasing the lead body 52, facilitating the smooth discharge of the entire component after welding is completed.

[0049] Example 3: Based on Example 2, Figure 16-Figure 18 As shown, it also includes a pushing mechanism arranged on the fixing frame 3 and the correction frame 641, and the pushing mechanism is used to push out the component body 51 and the lead body 52 that have been welded. A rotating rod 141 is rotatably installed on one of the fixing frames 3, and pushing plates 142 are respectively installed at both ends of the rotating rod 141. The sides of the two pushing plates 142 that are close to each other are respectively connected to the two sides of the fixing frame 3 through the torsion spring 2 143. A driving gear 144 is installed in the middle of the rotating rod 141, and a slot is provided on the correction frame 641. The driving gear 144 is located in the slot of the correction frame 641. A flat rack 145 is installed at the bottom of the slot of the correction frame 641. After the flat rack 145 moves, it engages with the driving gear 144.

[0050] When the correction frame 1 641 moves away from the correction frame 2 642, the correction frame 1 641 drives the flat rack 145 to engage with the driving gear 144, and the driving gear 144 drives the rotating rod 141 and the two pushing plates 142 to swing. At the same time, the two torsion springs 2 143 store elastic potential energy, and the two pushing plates 142 push the welded component body 51 and the lead body 52 out of the work station exit simultaneously, preventing the components from being retained in the work station and causing jamming, thereby improving the discharge smoothness and equipment operation stability; when the correction frame 1 641 moves in the opposite direction, the flat rack 145 synchronously drives the driving gear 144, the rotating rod 141 and the pushing plate 142 to rotate in the opposite direction. After the flat rack 145 disengages from the driving gear 144, the rotating rod 141 and the pushing plate 142 automatically reset under the elastic force of the two torsion springs 2 143, preparing for the next round of component discharge action, forming an automatic, continuous and efficient discharge mechanism, and improving the welding rhythm and operation smoothness of the overall device.
