Technical Field
[0001] This invention belongs to the field of welding system technology, specifically an intelligent welding system for furniture assembly. Background Technology
[0002] Traditional furniture assembly and welding processes have long relied primarily on manual labor. This method is not only inefficient and often limited by the skills and experience of the workers, but also struggles to guarantee consistent assembly precision, resulting in inconsistent product quality. Furthermore, manual assembly and welding is physically demanding, requiring significant physical strength and endurance from workers. Prolonged exposure to such work can easily lead to occupational diseases such as vision loss and muscle strain. More worryingly, the safety hazards of open flames, high temperatures, and flying sparks in the manual working environment constantly threaten the safety of operators, increasing the risk of accidents. Summary of the Invention
[0003] To address the problems mentioned in the background art, the present invention provides the following technical solution: an intelligent welding system for furniture assembly, including a workbench, with a first loading position and a second loading position respectively arranged on different sides of the workbench, the first loading position and the second loading position being capable of loading operations respectively, and a welding machine also arranged on the workbench, when the workpiece is pushed to a predetermined position by the first loading position and the second loading position respectively, the welding machine is capable of welding and fixing the connection position of the workpiece;
[0004] Both the first and second loading positions include a box body with an open top. A pusher is installed on one side of the box body, with its output end extending into the box body. A push plate is fixed to the output end of the pusher. A toggle structure is installed on the other side of the box body. The toggle structure can rotate, and a channel is provided on the adjacent side of the toggle structure. The side of the toggle structure extends into the box body. The pusher pushes the workpiece toward the toggle structure, and the side of the workpiece can press against the side of the toggle structure. This allows the workpiece to slide out of the box body through the channel when the toggle structure rotates. A transmission structure is also provided inside the box body. When the toggle structure slides the workpiece it contacts, one end of the transmission structure can be tilted upward to prevent the next workpiece from contacting the toggle structure. When the workpiece has completely slid out of the box body, the next workpiece can contact the toggle structure.
[0005] The welding machine is mounted on a track, and it can move along the track toward / away from the contact point of two workpieces;
[0006] The workbench is also equipped with a locking block, which has a first slide and a second slide. Two workpieces can enter the first slide and the second slide respectively. The locking block can slide along a direction parallel to the second loading position. When the locking block slides, the first loading position can slide away from the workbench.
[0007] Preferably, the actuating structure includes a driving wheel and a driven wheel, and a rotating shaft is fixedly connected to the axis of each of the driving wheel and the driven wheel. A chain is provided outside the rotating shaft. When the driving wheel rotates, the driven wheel can be driven to rotate synchronously by the use of the chain.
[0008] Preferably, the transmission structure includes a toggle block and a limiting baffle. A first rotating shaft is fixedly connected to the toggle block, and a first torsion spring is sleeved on the first rotating shaft. One end of the toggle block has an inclined surface that extends upward into the box. The lower end of the inclined surface extends inward into the box, and the higher end extends outward from the box. A second rotating shaft is fixedly connected to the limiting baffle, and a second torsion spring is sleeved on the second rotating shaft. When the second torsion spring is not subjected to external force, the end of the limiting baffle away from the second rotating shaft tilts upward.
[0009] Preferably, a connecting rope is installed at the lower end of the actuating block, and the other end of the connecting rope is connected to the end of the limiting baffle near the raised end. When the workpiece slides out of the channel, the lower wall of the workpiece can press on the actuating block and make it rotate downward. At this time, one end of the limiting baffle is raised upward to prevent the next workpiece from contacting the actuating structure. When the workpiece is separated from the channel, the actuating block is raised upward, and the connecting rope pulls the raised end of the limiting baffle downward.
[0010] Preferably, a first toothed plate is provided outside the first rotating shaft, and the first rotating shaft and the first toothed plate mesh with each other; a second toothed plate is provided outside the second rotating shaft, and the second rotating shaft and the second toothed plate mesh with each other; the first toothed plate and the second toothed plate are connected by a spring.
[0011] Preferably, a support frame is provided on the track, a first threaded rod is provided inside the support frame, an mounting plate is externally threaded to the first threaded rod, a welding machine is provided on the mounting plate, a second threaded rod is provided inside the track, the lower end of the support frame is sleeved on the second threaded rod, and there is a threaded fit between the support frame and the second threaded rod.
[0012] Preferably, a base is provided below one of the boxes, and the boxes can slide on the base. A third threaded rod is rotatably installed inside the base. A gear is fixed to one end of the third threaded rod. A mating block is fixed to the lower end of the box and threadedly sleeved on the outside of the third threaded rod. A connecting rod is fixed to one side of the locking block, and a rack plate is fixed to the end of the connecting rod. The rack plate can engage with the gear.
[0013] Preferably, a rotatable fourth threaded rod is provided inside the worktable, and the fourth threaded rod is threadedly engaged with the locking block.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] When this system was implemented, the working effect was stable and no personnel were required to operate it, which greatly improved the safety and reliability of welding.
[0016] The first and second loading positions contain multiple workpieces. The workpiece in the first loading position slides out first, and then the workpiece in the second loading position slides out. When the two workpieces come into contact, the welding machine can weld the connection position of the two workpieces, thereby achieving the purpose of automated welding.
[0017] After the workpiece is loaded into the box, the pusher pushes the surface of the workpiece against the side of the actuating structure. Then the actuating structure rotates, sliding the workpiece in contact with the actuating structure out of the box. After the workpiece in contact with the actuating structure separates from the box, the next workpiece can be pushed to the side of the actuating structure for the next loading.
[0018] The use of the clamping block facilitates the removal of the welded workpiece from the welding position during the implementation of this system, making it easier to unload the workpiece. Attached Figure Description

[0028] 100, First loading position; 200, Second loading position. Detailed Implementation
[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort 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 furniture assembly, including a workbench 1. A first loading position 100 and a second loading position 200 are respectively arranged on different sides of the workbench 1. The first loading position 100 and the second loading position 200 are respectively capable of loading operations. A welding machine 2 is also arranged on the workbench 1. When the first loading position 100 and the second loading position 200 push the workpiece to the predetermined position, the welding machine 2 can weld and fix the connection position of the workpiece.
[0031] When this system is implemented, the first loading position 100 and the second loading position 200 contain multiple workpieces. The workpieces in the first loading position 100 slide out first, and the workpieces in the second loading position 200 slide out next. When the two workpieces come into contact, the welding machine 2 can weld the connection position of the two workpieces, thereby achieving the purpose of automated welding.
[0032] Both the first loading station 100 and the second loading station 200 include a box body 6, which is an open structure at the top. 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. A push plate 8 is fixed to the output end of the pusher 7. A toggle structure is installed on the other side of the box body 6. The toggle structure can rotate, and 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. 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 it contacts, one end of the transmission structure can be tilted upward to prevent the next workpiece from contacting the toggle structure. When the workpiece is completely slid out of the box body 6, the next workpiece can contact the toggle structure.
[0033] After the workpiece is loaded into the housing 6, the pusher 7 presses the surface of the workpiece against the side of the actuating structure. Then, the actuating structure rotates, sliding the workpiece in contact with the actuating structure out of the housing 6. Once the workpiece in contact with the actuating structure separates from the housing 6, the next workpiece can be pushed to the side of the actuating structure for easy loading next time.
[0034] The width of channel 26 is just enough for one workpiece to pass through, preventing the next workpiece from sliding out of the box 6 along with it due to the friction between the two workpieces when one workpiece slides out.
[0035] When the workpiece slides out of the housing 6 (but not completely out), after the workpiece moves forward, there is a gap between the next workpiece and the actuating mechanism. To prevent the next workpiece from contacting the actuating mechanism at this time, a transmission structure is provided. Only after the slidable workpiece has completely slid out of the housing 6 can the next workpiece contact the actuating mechanism.
[0036] The welding machine 2 is mounted on the track 3. The welding machine 2 can move along the track 3 toward / away from the contact point of the two workpieces, which facilitates the welding of the workpiece connection position by the welding machine 2.
[0037] A locking block 5 is also provided inside the worktable 1. The locking block 5 is provided with a first slide rail 21 and a second slide rail 22. Two workpieces can enter the first slide rail 21 and the second slide rail 22 respectively. The locking block 5 can slide in a direction parallel to the second loading position 100. When the locking block 5 slides, the first loading position 100 can slide away from the worktable 1.
[0038] The use of block 5 serves two purposes: first, it allows the welded workpiece to be pushed away from the welding position after the welding process is complete; second, it allows the workpiece to be moved upwards before welding. Figure 1(as shown in the direction) so that the horizontally placed workpiece can make tight contact with the vertically placed workpiece.
[0039] The actuation structure includes a driving wheel 10 and a driven wheel 9. A rotating shaft 11 is fixedly connected to the axis of both the driving wheel 10 and the driven wheel 9. A chain 12 is provided 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 structure includes a toggle block 27 and a limiting baffle 30. A first rotating shaft 28 is fixedly connected to the toggle block 27, 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, which extends upward and into the housing 6. The lower end of the inclined surface extends inward toward the housing 6, and the higher end of the inclined surface extends outward toward the housing 6. A second rotating shaft 31 is fixedly connected to the limiting baffle 30, and a second torsion spring 32 is sleeved on the second rotating shaft 31. When the second torsion spring 32 is not subjected to external force, the end of the limiting baffle 30 away from the second rotating shaft 31 tilts upward.
[0041] When the workpiece is not moved by the actuating structure, the first torsion spring 29 causes the actuating block 27 to be in the state shown in the figure. At this time, the limiting baffle 30 is pulled into the inner wall of the box 6, and the second torsion spring 32 is in a compressed state. When the workpiece is slid, the workpiece presses the actuating block 27 downward. At this time, the limiting baffle 30 can rotate upward to prevent the next workpiece from contacting the actuating structure. When the workpiece completely slides away from the box 6, the first torsion spring 29 lifts the actuating block 27 upward, and the end of the actuating block 27 extends into the channel 26 again. At this time, the limiting baffle 30 is pulled back into the inner wall of the box 6, and the next workpiece can contact the surface of the actuating structure.
[0042] The elastic force of the first torsion spring 29 is greater than that of the second torsion spring 32.
[0043] As a first embodiment of the actuating block 27 and the limiting baffle 30:
[0044] One end of a connecting rope 33 is installed at the lower end of the actuating block 27, and the other end of the connecting rope 33 is connected to the end of the limiting baffle 30 near the raised end. When the workpiece slides out of the channel 26, the lower wall of the workpiece can press on the actuating block 27 and make it rotate downward. At this time, one end of the limiting baffle 30 is raised upward to prevent the next workpiece from contacting the actuating structure. When the workpiece is separated from the channel 26, the actuating block 27 is raised upward, and the connecting rope 33 pulls the raised end of the limiting baffle 30 downward.
[0045] By using the connecting rope 33, it is convenient to make a transmission connection between the toggle block 27 and the limit baffle 30, thereby facilitating the control of the limit baffle 30.
[0046] As a second embodiment of the actuating block 27 and the limiting baffle 30:
[0047] A first toothed plate 34 is provided outside the first rotating shaft 28, and the first rotating shaft 28 and the first toothed plate 34 mesh with each other. A second toothed plate 36 is provided outside the second rotating shaft 31, and the second rotating shaft 31 and the second toothed plate 36 mesh with each other. The first toothed plate 34 and the second toothed plate 36 are connected by a spring 35.
[0048] The control of the limit baffle 30 can be achieved through the cooperation between the first toothed plate 34, the spring 35 and the second toothed plate 36, 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 position of the vertical workpiece from moving when the locking block 5 pulls the horizontal workpiece to the end of the vertical workpiece.
[0050] A support frame 13 is provided on the track 3. A first threaded rod 14 is provided inside the support frame 13. The first threaded rod 14 is externally threaded to a mounting plate 15. The welding machine 2 is provided on the mounting plate 15. A second threaded rod 16 is provided inside the track 3. The lower end of the support frame 13 is fitted over the second threaded rod 16, and the support frame 13 and the second threaded rod 16 are threaded together.
[0051] When the welding machine 2 is in operation, it not only needs to move closer to / 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 method, the welding machine 2 can be moved.
[0052] A base 17 is provided below one of the boxes 6, and the box 6 can slide on the base 17. A third threaded rod 18 is rotatably installed inside the base 17. A gear 19 is fixedly connected to one end of the third threaded rod 18. A mating block 20 is fixedly connected to the lower end of the box 6. The mating block 20 is threaded onto the outside of the third threaded rod 18. A connecting rod 24 is fixedly connected to one side of the locking block 5. A rack plate 25 is fixedly connected to the end of the connecting rod 24. The rack plate 25 can cooperate with the gear 19.
[0053] In the implementation of this device, in order to ensure the stability of the workpiece, when the workpiece slides out of the box 6 and the two workpieces come into contact, the ends of the two workpieces are still completely separated from the channel 26, thereby ensuring the stability of the workpiece. When the locking block 5 pushes the welded workpiece, in order to avoid interference between the horizontally placed workpiece and the box 6, the rack plate 25 can cooperate with the gear 19 to make the box 6 slide away from the worktable 1, thereby allowing the workpiece to slide. When the locking block 5 resets, the box 6 can also reset accordingly.
[0054] Inside the workbench 1 is a rotatable fourth threaded rod 23, which is threadedly engaged with the locking block 5, thereby causing the locking block 5 to move back and forth.
[0055] The first threaded rod 14, the second threaded rod 16, the third threaded rod 18, and the fourth threaded rod 23 can all be driven by a motor.
[0056] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
