Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, and more specifically, to a welding carrier diversion and conveying device. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. During the workpiece processing, the workpiece processing equipment is usually located inside a cleanroom to prevent external dust from entering the processing equipment and affecting the workpiece processing. When welding is required, the workpiece to be welded is placed on a carrier 6, and the position of the workpiece is fixed by the carrier 6. Then, the conveying equipment moves the carrier to transfer the workpiece to the position of the welding device, so that the welding device can weld the workpiece on the carrier 6. The conveying equipment removes the welded workpiece to complete the welding process. However, existing conveying equipment is difficult to distribute the carrier 6 to multiple workstations for simultaneous processing, resulting in queuing and waiting situations on the same conveying line due to the slow processing speed of a certain link. This seriously affects the production cycle and capacity, and cannot meet the needs of large-scale flexible production. In view of this, we propose a welding carrier diversion conveying device. Utility Model Content

[0003] The purpose of this utility model is to provide a welding carrier diversion and conveying device to solve the problem mentioned in the background art that the conveying equipment is difficult to distribute the carrier to multiple workstations for simultaneous processing, resulting in the slow processing speed of the carrier on the same conveying line affecting the production efficiency of the workpiece.

[0004] To address the aforementioned problems, the present invention aims to provide a welding carrier diversion and conveying device, comprising three sets of conveying mechanisms. Each conveying mechanism includes a first placement component, a second placement component, and a third placement component. These components are used to place and convey the carrier. A lower feeding mechanism is provided between adjacent sets of conveying mechanisms, driving the carrier to move and thus moving the workpiece. A lifting mechanism is provided on one side of the second placement component, causing it to move upwards or downwards. When the second placement component reaches its lowest point, the upper sides of the first, second, and third placement components and the lower feeding mechanism are on the same plane. A material-shifting mechanism is provided on one side of the third placement component, driving the carrier on the third placement component to move onto the lower feeding mechanism. An upper feeding mechanism is provided at the top between adjacent lifting mechanisms. When the second placement component reaches its highest point, the upper sides of the second placement component and the upper feeding mechanism are on the same plane, and the carrier on the second placement component moves onto the upper feeding mechanism, which then conveys the carrier. The two upper feeding mechanisms are located above the two lower feeding mechanisms.

[0005] As a further improvement to this technical solution, the lower feeding mechanism includes a fixed frame. Two limiting grooves are opened on the top of the opposite side walls inside the fixed frame. The two sides of the carrier are slidably connected inside the two limiting grooves. Under the restriction of the limiting grooves, the carrier is prevented from separating from the fixed frame, so that the carrier moves along the axial direction of the limiting groove. Several positioning components are provided on one side of the fixed frame, and the positioning components fix the carrier inside the fixed frame.

[0006] As a further improvement to this technical solution, a guide rail is fixedly connected to the inner wall of the fixed frame near the top. A movable rod is slidably connected to the guide rail. Several pushing components are provided on the movable rod. A third movable frame is fixedly connected to one side of the movable rod. A third driving component is provided on one side of the fixed frame. The third driving component drives the third movable frame to move, causing it to move the movable rod along the axis of the guide rail. During the movement, the movable rod drives the pushing components to move, causing it to move the carrier.

[0007] As a further improvement to this technical solution, the pushing assembly includes a support rod fixedly connected to the upper side of the moving rod. A push block is hinged to the top of the support rod. The top of one side of the push block is an inclined surface. A compression spring is fixedly connected to the top of the support rod. The upper end of the compression spring is fixedly connected to one side of the bottom of the push block. When the compression spring is in a compressed state, the compression spring relaxes and drives the push block to rotate, causing the push block to rotate at a small angle under the restriction of the support rod.

[0008] As a further improvement to this technical solution, the upper feeding mechanism includes a support frame, with several transmission rollers rotatably connected inside the support frame, and a conveyor belt drivingly connected to the outside of the several transmission rollers. During the rotation of the transmission rollers, the conveyor belt is driven to rotate, thereby driving the carrier to move. Two limiting components are provided on one side of the support frame near the end, and the limiting components block the movement path of the carrier.

[0009] As a further improvement to this technical solution, the lifting mechanism includes a first driving component and a first movable frame. The first driving component drives the first movable frame to move upward or downward. The second placement component is fixedly connected to the side of the first movable frame away from the first driving component. During the movement, the first movable frame drives the second placement component to move.

[0010] As a further improvement to this technical solution, the feeding mechanism includes a second driving component and a second moving frame. The second driving component drives the second moving frame to move back and forth. The second driving component connects the third placing component and the second moving frame together. A material blocking component is provided on the second moving frame near the third placing component.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This welding carrier diversion and conveying device moves the carrier to the left lower feeding mechanism via a left conveying mechanism and a material feeding mechanism. The left lower feeding mechanism drives the carrier to move. During this process, the left lifting mechanism drives the left second placement component to rise, so that the carrier on the left second placement component moves to the left upper feeding mechanism and is transferred to the right lower feeding mechanism via the middle conveying mechanism. The two lower feeding mechanisms move the two carriers to the bottom of the two welding devices respectively. The welding devices perform multi-station welding processing on the workpiece. At the same time, the left upper feeding mechanism places multiple carriers and workpieces to avoid the carriers from blocking the conveying mechanism and affecting the processing efficiency of the workpiece, thereby improving the processing efficiency of workpiece welding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 - Figure 3 , Figure 9 and Figure 10As shown, the purpose of this embodiment is to provide a welding carrier diversion and conveying device, including three sets of conveying mechanisms. Each conveying mechanism includes a first placement assembly 1, a second placement assembly 11, and a third placement assembly 12. These three sets of mechanisms are used to place and convey the carrier 6. A lower feeding mechanism 4 is provided between adjacent sets of conveying mechanisms. The lower feeding mechanism 4 drives the carrier 6 to move, causing it to move the workpiece. A lifting mechanism 2 is provided on one side of the second placement assembly 11. The lifting mechanism 2 drives the second placement assembly 11 to move upwards or downwards. When the second placement assembly 11 moves to its lowest position, the first placement assembly 1... The upper sides of the second placement component 11, the third placement component 12 and the lower feeding mechanism 4 are located on the same plane. A feeding mechanism 3 is provided on one side of the third placement component 12. The feeding mechanism 3 drives the carrier 6 on the third placement component 12 to move onto the lower feeding mechanism 4. An upper feeding mechanism 5 is provided at the top between two adjacent lifting mechanisms 2. When the second placement component 11 moves to the highest position, the upper sides of the second placement component 11 and the upper feeding mechanism 5 are located on the same plane. The carrier 6 on the second placement component 11 moves onto the upper feeding mechanism 5. The upper feeding mechanism 5 transports the carrier 6. The two upper feeding mechanisms 5 are located above the two lower feeding mechanisms 4 respectively.

[0035] The first placement assembly 1, the second placement assembly 11, and the third placement assembly 12 drive the carrier 6 to move, transporting the carrier 6 to the lower feeding mechanism 4 and the upper feeding mechanism 5, or removing the carrier 6 from the lower feeding mechanism 4 and the upper feeding mechanism 5. The first placement assembly 1, the second placement assembly 11, and the third placement assembly 12 all include a placement frame. Several conveying rollers are rotatably connected inside the placement frame. A geared motor is fixedly connected inside the placement frame. The output shaft of the geared motor is coaxially driven to the conveying rollers through a coupling. The output shaft of the geared motor drives the conveying rollers to rotate. A conveyor belt is driven to the outside of the several conveying rollers. The conveyor belt drives the carrier 6 to move during rotation.

[0036] The lifting mechanism 2 drives the second placement component 11 to rise or fall, changing the position of the second placement component 11, so that the carrier 6 on the second placement component 11 can be moved to a different mechanism, or the carrier 6 on a different mechanism can be moved to the second placement component 11, thereby completing the diversion and conveying process of the carrier 6. (Refer to...) Figure 9 and Figure 11The lifting mechanism 2 includes a first drive assembly and a first movable frame 21. The first drive assembly drives the first movable frame 21 to move up or down. The second placement assembly 11 is fixedly connected to the side of the first movable frame 21 away from the first drive assembly. The placement frame of the second placement assembly 11 is fixedly connected to the first movable frame 21. During the movement of the first movable frame 21, it drives the second placement assembly 11 to move. The moving second placement assembly 11 drives the carrier 6 to move. When the second placement assembly 11 moves to the lowest position, the carrier 6 on the second placement assembly 11 moves to the third placement assembly 12. When the second placement assembly 11 moves to the highest position, the carrier 6 on the second placement assembly 11 moves to the upper feeding mechanism 5.

[0037] When the carrier 6 on the third placement assembly 12 moves onto the lower feeding mechanism 4, both sides of the carrier 6 need to enter the interior of the lower feeding mechanism 4. The moving carrier 6 slides against the inner wall of the lower feeding mechanism 4, hindering its normal movement and making it difficult to move onto the lower feeding mechanism 4. The feeding mechanism 3 then moves the carrier 6 closer to the lower feeding mechanism 4, thus moving the carrier 6 on the third placement assembly 12 onto the lower feeding mechanism 4. (Refer to...) Figure 9 and Figure 12 The feeding mechanism 3 includes a second drive assembly and a second moving frame 31. The second drive assembly drives the second moving frame 31 to reciprocate. The second drive assembly connects the third placement assembly 12 and the second moving frame 31 together. A material blocking assembly is provided on the second moving frame 31 near the third placement assembly 12. The material blocking assembly includes a first cylinder 32 fixedly connected to the second moving frame 31. The piston rod of the first cylinder 32 is fixedly connected to a feeding plate 33. During the extension and retraction of the piston rod of the first cylinder 32, the feeding plate 33 moves up or down.

[0038] During the movement of the carrier 6 driven by the third placement assembly 12, the piston rod of the first cylinder 32 extends and drives the material-pulling plate 33 to move away from the second moving frame 31. The material-pulling plate 33 restricts the movement of the carrier 6 and prevents the carrier 6 from falling off the third placement assembly 12. When it is necessary to move the carrier 6 on the third placement assembly 12 to the lower feeding mechanism 4, the piston rod of the first cylinder 32 retracts and drives the material-pulling plate 33 to move closer to the second moving frame 31. The second drive assembly drives the first cylinder 32 and the material-pulling plate 33 to move, so that the material-pulling plate 33 moves to the other side of the carrier 6. At this time, the piston rod of the first cylinder 32 extends and drives the material-pulling plate 33 to move away from the second moving frame 31. The material-pulling plate 33 contacts the other side of the carrier 6. Subsequently, the second drive assembly drives the first cylinder 32 and the material-pulling plate 33 to move. The moving material-pulling plate 33 pushes the carrier 6 to move so that it moves to the lower feeding mechanism 4.

[0039] The lower feeding mechanism 4 moves the carrier 6 to a position corresponding to the welding device, facilitating welding of the workpiece on the carrier 6. When welding is complete, the lower feeding mechanism 4 moves the carrier 6 and the workpiece away from the welding device, allowing subsequent welding to proceed. (Reference) Figure 4 - Figure 7 The lower feeding mechanism 4 includes a fixed frame 41. Two limiting grooves 411 are formed on the top of the opposing side walls inside the fixed frame 41. The two sides of the carrier 6 are slidably connected inside the two limiting grooves 411. Under the constraint of the limiting grooves 411, the carrier 6 is prevented from detaching from the fixed frame 41, allowing the carrier 6 to move along the axial direction of the limiting grooves 411. Several positioning components are provided on one side of the fixed frame 41. The positioning components fix the carrier 6 inside the fixed frame 41. The positioning components include a second cylinder 43 fixedly connected to one side of the fixed frame 41. The piston rod of cylinder 43 passes through the fixed frame 41 and is fixedly connected to the positioning rod 431. During the extension and retraction of the piston rod of the second cylinder 43, the positioning rod 431 moves. When the workpiece of the carrier 6 needs to be welded, the piston rod of the second cylinder 43 extends and drives the positioning rod 431 to move towards the carrier 6. During the movement, the positioning rod 431 contacts one side of the carrier 6. The moving positioning rod 431 presses the carrier 6 into the limiting groove 411 to fix the carrier 6 inside the fixed frame 41, so that the carrier 6 is held in place during the workpiece welding process.

[0040] A guide rail 412 is fixedly connected to the inner wall of the fixed frame 41 near the top. A movable rod 421 is slidably connected to the guide rail 412. Several pushing components are provided on the movable rod 421. A third movable frame 42 is fixedly connected to one side of the movable rod 421. A third drive component is provided on one side of the fixed frame 41. The third drive component drives the third movable frame 42 to move, causing it to move the movable rod 421 along the axis of the guide rail 412. During the movement, the movable rod 421 drives the pushing components to move, causing it to move the carrier 6. The pushing components include a support rod 4 fixedly connected to the upper side of the movable rod 421. 22. A push block 423 is hinged to the top of the support rod 422. The top of one side of the push block 423 is a slope. A compression spring 424 is fixedly connected to the top of the support rod 422. The upper end of the compression spring 424 is fixedly connected to one side of the bottom of the push block 423. When the compression spring 424 is in a compressed state and is relaxing, the compression spring 424 will drive the push block 423, causing the push block 423 to rotate around the position hinged to the support rod 422. Under the restriction of the support rod 422, the push block 423 rotates at a small angle, while preventing the push block 423 from rotating in the opposite direction, ensuring that the push block 423 can only push the vehicle 6 in one direction.

[0041] After the workpiece welding is completed, the piston rod of the second cylinder 43 retracts, causing the positioning rod 431 to move away from the carrier 6, thus releasing the positioning rod 431 from fixing the carrier 6. Subsequently, the third drive assembly drives the third moving frame 42, the moving rod 421, the support rod 422, and the push block 423 to move away from the left third placement assembly 12. During the movement, the push block 423 moves the carrier 6, removing the carrier 6 from under the welding device and moving it to the middle first placement assembly 1. At the same time, a new carrier 6 is moved to the bottom of the welding device. At this time, the positioning component fixes the position of the carrier 6. The third drive component drives the third moving frame 42, the moving rod 421, the support rod 422 and the push block 423 to move towards the left side of the third placement component 12. During the movement, the inclined surface of the push block 423 contacts one side of the carrier 6. Under the restriction of the carrier 6, the push block 423 rotates and compresses the compression spring 424. The moving push block 423 moves along the bottom of the carrier 6. When the push block 423 separates from the carrier 6, the compression spring 424 in the compressed state relaxes and drives the push block 423 to rotate and reset.

[0042] refer to Figure 4 , Figure 11 and Figure 12 The first drive assembly, the second drive assembly, and the third drive assembly all include a mounting bracket. A gearbox is fixedly connected to the mounting bracket, and a screw is rotatably connected inside the mounting bracket. A drive motor is fixedly connected to one side of the mounting bracket. The output shaft of the drive motor is connected to the screw via the gearbox. The drive motor is a motor whose output shaft can rotate in both directions. The rotating output shaft of the drive motor drives the screw to rotate via the gearbox. The first movable frame 21, the second movable frame 31, and the third movable frame 42 are respectively threadedly connected to the screws of the first drive assembly, the second drive assembly, and the third drive assembly. During rotation, the three screws respectively drive the first movable frame 21, the second movable frame 31, and the third movable frame 42 to move.

[0043] The left upper feeding mechanism 5 moves the carrier 6 and the workpiece, transferring the unwelded workpiece to other welding stations for welding. This allows for simultaneous welding at multiple stations, improving welding efficiency. Simultaneously, the left and right upper feeding mechanisms 5 hold several unwelded and welded workpieces respectively, preventing blockages on the lower feeding mechanism 4 and the conveyor mechanism, which would affect processing efficiency. (Reference) Figure 8 The upper feeding mechanism 5 includes a support frame 51, a drive motor is fixedly connected inside the support frame 51, and several drive rollers are rotatably connected inside the support frame 51. The output shaft of the drive motor is coaxially connected to one end of the drive rollers through a coupling. The output shaft of the drive motor rotates and drives the drive rollers to rotate. A conveyor belt 511 is connected to the outside of the several drive rollers. During the rotation of the drive rollers, the conveyor belt 511 rotates and drives the carrier 6 to move.

[0044] Two limiting components are provided near the end of one side of the support frame 51. The limiting components block the movement path of the carrier 6. The limiting components include a third cylinder 52 fixedly connected to one side of the support frame 51. The piston rod of the third cylinder 52 passes through the support frame 51 and is fixedly connected to a stop rod 521. During the extension and retraction of the piston rod of the third cylinder 52, it drives the stop rod 521 to move. During the movement of the carrier 6 driven by the conveyor belt 511, the piston rod of the third cylinder 52 extends and drives the stop rod 521 to move. The stop rod 521 blocks the carrier 6 to prevent the carrier 6 from falling from the upper feeding mechanism 5 and affecting the welding of subsequent workpieces.

[0045] When using this device:

[0046] When welding is required, the workpiece to be welded is fixedly placed on the carrier 6, and the carrier 6 is moved to the first placement assembly 1 on the left. The carrier 6 of the first placement assembly 1 is moved to the second placement assembly 11 and the third placement assembly 12. Then, the left feeding mechanism 3 moves the carrier 6 on the third placement assembly 12 to the left lower feeding mechanism 4. The left lower feeding mechanism 4 drives the carrier 6 to move to the bottom of the left welding device, and the welding device performs welding on the workpiece on the carrier 6.

[0047] During this process, the new carrier 6 on the first placement component 1 moves to the second placement component 11, and the left lifting mechanism 2 drives the second placement component 11 to move upward. Subsequently, the second placement component 11 drives the carrier 6 to move to the left upper feeding mechanism 5. The upper feeding mechanism 5 places and transports several carriers 6 to avoid the carriers 6 causing blockage on the conveying mechanism.

[0048] After the workpiece on the left lower feeding mechanism 4 is welded, the left lower feeding mechanism 4 drives the carrier 6 to move to the middle first placement component 1. The carrier 6 on the first placement component 1 moves to the second placement component 11. At this time, the middle lifting mechanism 2 drives the second placement component 11 to move upward, so that the carrier 6 on the second placement component 11 moves to the right upper feeding mechanism 5. The right upper feeding mechanism 5 places and transports the welded workpiece and the carrier 6.

[0049] When the carrier 6 on the middle second placement assembly 11 moves to the right upper feeding mechanism 5, the carrier 6 on the left upper feeding mechanism 5 moves to the second placement assembly 11. Then, the middle lifting mechanism 2 drives the second placement assembly 11 to move downward, and the carrier 6 on the second placement assembly 11 moves to the third placement assembly 12. The middle feeding mechanism 3 moves the carrier 6 to the right lower feeding mechanism 4. The lower feeding mechanism 4 drives the carrier 6 to move, so that the welding device can perform welding on the workpiece on the carrier 6.

[0050] After the workpiece welding is completed, the right lower feeding mechanism 4 drives the carrier 6 to move to the right first placement assembly 1. The carrier 6 on the first placement assembly 1 moves to the third placement assembly 12 via the second placement assembly 11. During the workpiece welding process on the right lower feeding mechanism 4, the right lifting mechanism 2 drives the second placement assembly 11 to move upward. The carrier 6 on the right upper feeding mechanism 5 moves to the second placement assembly 11. Subsequently, the right lifting mechanism 2 drives the second placement assembly 11 to move downward. The carrier 6 on the second placement assembly 11 moves to the third placement assembly 12. The third placement assembly 12 moves the carrier 6 to the next processing step to perform subsequent processing on the workpiece.

[0051] The carrier 6 is moved to the left lower feeding mechanism 4 by the left conveying mechanism and the feeding mechanism 3. The left lower feeding mechanism 4 drives the carrier 6 to move. During this process, the left lifting mechanism 2 drives the left second placement component 11 to rise, so that the carrier 6 on the left second placement component 11 moves to the left upper feeding mechanism 5 and is transferred to the right lower feeding mechanism 4 through the middle conveying mechanism. The two lower feeding mechanisms 4 move the two carriers 6 to the bottom of the two welding devices respectively. The welding devices perform multi-station welding processing on the workpiece. At the same time, the left upper feeding mechanism 5 places multiple carriers 6 and workpieces to avoid the carriers 6 from getting blocked on the conveying mechanism, which would affect the processing efficiency of the workpiece and improve the processing efficiency of workpiece welding.
