[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Depend on Figure 1-7 The present invention discloses an intelligent welding system for assembling furniture, comprising a workbench 1, wherein a first loading position 100 and a second loading position 200 are respectively arranged on different sides of the workbench 1, and the first loading position 100 and the second loading position 200 can respectively perform loading operations, and a welding machine 2 is also arranged on the workbench 1, and when the first loading position 100 and the second loading position 200 respectively push the workpiece to a predetermined position, the welding machine 2 can weld and fix the connection position of the workpiece;

[0031] When the system is implemented, the first loading position 100 and the second loading position 200 are equipped with multiple workpieces. The workpieces in the first loading position 100 slide out first, and then the workpieces in the second loading position 200 slide out. When the two workpieces are in contact, the welding machine 2 can weld the connection position of the two workpieces, thereby achieving the purpose of automatic welding.

[0032] The first loading position 100 and the second loading position 200 both include a box body 6, which is a structure with an upper end open. A pusher 7 is installed on one side of the box body 6, and the output end of the pusher 7 extends into the box body 6, and a push plate 8 is fixedly connected to the output end of the pusher 7. A toggle structure is installed on the other side of the box body 6, and the toggle structure can rotate. A channel 26 is provided on the adjacent side of the toggle structure. The side of the toggle structure extends into the box body 6, and the pusher 7 pushes the workpiece toward the toggle structure, and the side of the workpiece can press against the side of the toggle structure, so that when the toggle structure rotates, the workpiece can slide out of the box body 6 through the channel 26. A transmission structure is also provided inside the box body 6. When the toggle structure slides the workpiece in contact with it, one end of the transmission structure can tilt upward to prevent the next workpiece from contacting the toggle structure, and when the workpiece completely slides out of the box body 6, the next workpiece can contact the toggle structure.

[0033] After the workpiece is loaded into the box body 6, the pusher 7 pushes the surface of the workpiece against the side of the toggle structure, and then the toggle structure rotates to slide the workpiece in contact with the toggle structure out of the box body 6. When the workpiece in contact with the toggle structure is separated from the box body 6, the next workpiece can be pushed to the side of the toggle structure to facilitate the next loading.

[0034] The width of the channel 26 is just enough to pass a workpiece, so as to avoid the situation that when one of the workpieces slides out of the box body 6, the friction between the two workpieces may cause the next workpiece to slide out of the box body 6.

[0035] When the workpiece slides out of the box body 6 (when the workpiece has not completely slid out of the box body 6), after the workpiece moves forward, there is a gap between the next workpiece and the toggle structure. In order to prevent the next workpiece from contacting the toggle structure at this time, a transmission structure is provided. The next workpiece can contact the toggle structure only after the slid workpiece completely slides out of the box body 6.

[0036] The welding machine 2 is installed on the track 3, and the welding machine 2 can move along the track 3 toward / away from the contact point of the two workpieces, thereby facilitating the welding of the connection position of the workpieces by the welding machine 2;

[0037] A block 5 is also provided in the workbench 1, and a first slideway 21 and a second slideway 22 are provided on the block 5. Two workpieces can enter the first slideway 21 and the second slideway 22 respectively. The block 5 can slide in a direction parallel to the second loading position 200, and when the block 5 slides, the first loading position 100 can slide in a direction away from the workbench 1.

[0038] The use of the clamp block 5, firstly, can push the welded workpiece away from the welding position after the welding machine is completed; secondly, can move upward ( Figure 1The horizontal workpiece can be in close contact with the vertical workpiece.

[0039] The shifting structure includes a driving wheel 10 and a driven wheel 9. A rotating shaft 11 is fixedly connected to the axes of the driving wheel 10 and the driven wheel 9 respectively. A chain 12 is arranged outside the rotating shaft 11. When the driving wheel 10 rotates, the driven wheel 9 can be driven to rotate synchronously through the use of the chain 12.

[0040] like Figure 5-7 As shown, the transmission member includes a toggle block 27 and a limit baffle 30, the toggle block 27 is fixedly connected to a first rotating shaft 28, and a first torsion spring 29 is sleeved on the first rotating shaft 28, one end of the toggle block 27 has an inclined surface, and the inclined surface extends upward and extends into the box body 6, the lower end of the inclined surface extends toward the interior of the box body 6, and the higher end of the inclined surface extends toward the outside of the box body 6, the limit baffle 30 is fixedly connected to a second rotating shaft 31, and a second torsion spring 32 is sleeved on the second rotating shaft 31, and when the second torsion spring 32 is not subjected to external force, the end of the limit baffle 30 away from the second rotating shaft 31 is tilted upward.

[0041] When the workpiece is not moved by the toggle structure, the first torsion spring 29 makes the toggle block 27 be in the state shown in the figure, at this time, the limit baffle 30 is pulled to the inner wall of the box body 6, and the second torsion spring 32 is in a compressed state; when the workpiece is slid, the workpiece presses the toggle block 27 downward, at this time the limit baffle 30 can rotate upward to prevent the next workpiece from contacting the toggle structure; when the workpiece completely slides out of the box body 6, the first torsion spring 29 lifts the toggle block 27 upward, and the end of the toggle block 27 extends into the channel 26 again, at this time the limit baffle 30 is pulled back to the inner wall of the box body 6, and the next workpiece can contact the surface of the toggle structure.

[0042] The elastic force of the first torsion spring 29 is greater than the elastic force of the second torsion spring 32 .

[0043] As a first embodiment of the toggle block 27 and the limit baffle 30:

[0044] One end of a connecting rope 33 is installed at the lower end of the toggle block 27, and the other end of the connecting rope 33 is connected to the end of the limit baffle 30 close to the tilting. When the workpiece slides out of the channel 26, the lower wall of the workpiece can press on the toggle block 27 to make it rotate downward. At this time, one end of the limit baffle 30 tilts upward to prevent the next workpiece from contacting the toggle structure. When the workpiece is separated from the channel 26, the toggle block 27 tilts upward, and the connecting rope 33 pulls the tilted end of the limit baffle 30 downward.

[0045] By using the connecting rope 33 , it is possible to facilitate transmission connection between the toggle block 27 and the limit baffle 30 , thereby facilitating control of the limit baffle 30 .

[0046] As a second embodiment of the toggle block 27 and the limit baffle 30:

[0047] A first tooth plate 34 is disposed outside the first rotating shaft 28 , and the first rotating shaft 28 and the first tooth plate 34 are meshed with each other. A second tooth plate 36 is disposed outside the second rotating shaft 31 , and the second rotating shaft 31 and the second tooth plate 36 are meshed with each other. The first tooth plate 34 and the second tooth plate 36 are connected by a spring 35 .

[0048] Through the cooperation among the first tooth plate 34, the spring 35 and the second tooth plate 36, the limit baffle 30 can be controlled, so as to facilitate the use of the user and make it more stable and durable.

[0049] The use of the toggle block 27 can also prevent the vertical workpiece from moving when the clamping block 5 tightens the horizontal workpiece to the end of the vertical workpiece.

[0050] A support frame 13 is arranged on the track 3, a first threaded rod 14 is arranged inside the support frame 13, the first threaded rod 14 is externally threadedly connected to a mounting plate 15, the welding machine 2 is arranged on the mounting plate 15, a second threaded rod 16 is arranged inside the track 3, the lower end of the support frame 13 is sleeved outside the second threaded rod 16, and the support frame 13 and the second threaded rod 16 are threadedly matched.

[0051] When the welding machine 2 is implemented, it not only needs to approach / move away from the contact position of the two workpieces, but also needs to move up and down in the vertical direction to weld the connection. Through the above implementation, the welding machine 2 can be moved.

[0052] A base 17 is provided under one of the box bodies 6, and the box body 6 can slide on the base 17. A third threaded rod 18 is rotatably installed in the base 17, and a gear 19 is fixedly connected to one end of the third threaded rod 18. A matching block 20 is fixedly connected to the lower end of the box body 6, and the matching block 20 is threadedly sleeved on the outside of the third threaded rod 18. A connecting rod 24 is fixedly connected to one side of the clamping block 5, and a rack plate 25 is fixedly connected to the end of the connecting rod 24, and the rack plate 25 can cooperate with the gear 19.

[0053] When the device is implemented, in order to ensure the stability of the workpiece, when the workpiece slides out of the box body 6 and the two workpieces are against each other, the ends of the two workpieces are still completely separated from the channel 26, thereby ensuring the stability of the workpiece. When the clamping block 5 pushes the welded workpiece, in order to avoid interference between the horizontally placed workpiece and the box body 6, the rack plate 25 can cooperate with the gear 19 to make the box body 6 slide in the direction away from the workbench 1, thereby allowing the workpiece to be slid, and when the clamping block 5 is reset, the box body 6 can also be reset accordingly.

[0054] A rotatable fourth threaded rod 23 is disposed inside the workbench 1 . The fourth threaded rod 23 is threadably matched with the clamping block 5 , thereby enabling the clamping block 5 to move forward and backward.

[0055] The first threaded rod 14 , the second threaded rod 16 , the third threaded rod 18 and the fourth threaded rod 23 may all be driven by a motor.
