Description

Technical Field

[0001] This invention relates to the field of intelligent display cabinet welding technology, specifically to a welding processing device and welding processing method for intelligent display cabinets. Background Technology

[0002] With the rapid development of smart manufacturing and the retail industry, the demand for smart display cases is increasing. These cases often contain complex metal frames and metal display rod structures that require welding. These welding operations are usually carried out inside narrow, enclosed display cases where space is extremely limited, placing extremely high demands on the flexibility, compactness, and reliability of welding equipment.

[0003] The following problems exist in the existing technology: 1. There are two existing technical solutions: one is to use a multi-joint robot, which is highly flexible but expensive; the other is to use manual labor with special welding fixtures, which requires high manual skills.

[0004] 2. When welding metal frames and metal display hanging rods, the multi-angle adjustment of the welding gun is crucial. However, some welding angles are difficult to handle. Designs that attempt to increase the degree of freedom often result in bulky end mechanisms, increased inertia, and inability to operate flexibly in confined spaces, which also affects the accuracy of movement. Summary of the Invention

[0010] Furthermore, a limit-positioning flipping rod is rotatably connected to the outer side of the fixed rotating shaft.

[0011] Furthermore, a flip bracket is fixedly connected to the outer side of the output flip ring, and active flip rings are rotatably connected to both sides of the flip bracket. Active flip rods with different directions are fixedly connected to the outer side of the two active flip rings. A steering output bracket is fixedly connected to the end of each of the two active flip rods away from the active flip rings. Two symmetrical steering driven rods are rotatably connected to the outer side of the steering output bracket. The active flip rods and the steering driven rods have the same length, forming a rhombus. The steering driven rods on both sides are rotatably connected to the same steering connecting bracket.

[0012] Furthermore, the flipping limiting mechanism includes a limiting connecting frame, which is fixedly connected to the outside of the connecting fixing tube. A protective baffle is fixedly connected to the outside of the limiting connecting frame. A limiting guide arc plate is fixedly connected to the end of the limiting connecting frame away from the connecting fixing tube. A guide groove is provided on the inner side of the limiting guide arc plate.

[0013] Furthermore, the welding output mechanism includes a welding control head, which is fixedly connected to the outside of the steering connection bracket. A controller is fixedly connected to the outside of the welding control head, and a display panel is provided on the outside of the controller. An output welding gun is fixedly connected to the end of the welding control head away from the steering connection bracket, and a protective chamber is fixedly connected to the outside of the output welding gun.

[0014] Furthermore, the welding protection mechanism includes two movable connecting rings, both of which are located on the outside of the corresponding steering output brackets. The same movable guide bracket is slidably connected to the outside of the two movable connecting rings. A lifting and rotating bracket is fixedly connected to the end of the movable connecting ring away from the second drive mechanism. A corresponding pipe bracket is rotatably connected to the inside of the two lifting and rotating brackets. The same mounting plate is rotatably connected to the two pipe brackets. A preheating pipe is installed on the inside of the mounting plate. The input end of the preheating pipe is connected to an external gas tank. A gas valve is installed at the output end of the preheating pipe. A gas guide pipe is fixedly connected to the end of the gas valve away from the preheating pipe. A venting frame is connected to the end of the gas guide pipe away from the gas valve. The ventilation frame includes a half-tube, with a cross bracket rotatably connected to the inner side of the half-tube.

An air jet port is opened at one end of the outer side of the cross bracket corresponding to the protective cabin, and an air intake port is opened on the outer side wall of the cross bracket that does not correspond to the protective cabin.

[0015] A welding process for an intelligent display cabinet, performed by the aforementioned welding device for intelligent display cabinets, includes the following steps: Step 1: First, install the display rods that need to be welded into the display case in the corresponding positions inside the display case, and fix the rods to be welded by means of adhesive or other methods. Then, select the appropriate positioning strip according to the actual situation, and select the appropriate control tooth strip on the outside of the positioning strip according to the length and curvature. Then, install the fixing bracket at the mounting bracket position on the inside of the positioning strip to complete the preparation work before welding. Step 2: After the preparation is completed, use the external control mechanism to control the direction input rod. Adjust the height and position of the movable base through the direction input rod to move the output welding gun to the welding position. Then, control the first drive motor to control the angle of the rotating bracket and rotate the output welding gun to the position close to the display hanging rod that needs to be welded. Step 3: After completing the previous step, control the gear output motor according to the actual welding angle required. The gear output motor rotates through the steering output gear to adjust the position of the positioning belt inside the gear belt bracket, thereby controlling the position of the mounting bracket and adjusting the angle of the output welding gun. Step 4: After the adjustment in the previous step is completed, further control the output of the second drive motor so that the output of the second drive motor drives the second drive rod to move, so that the output flip ring drives the flip bracket and flips the active flip ring to the corresponding position. The movement of the active flip ring will drive the active flip rod on its outer side to move, so that the steering output brackets on both sides move and drive the angle of the steering connecting bracket to flip. When the steering connecting bracket is driven by the steering driven rod, the steering connecting bracket will move under the guidance of the guide groove on the inner side of the limit guide arc plate, so as to further fine-tune the output angle of the output welding gun. Step 5: After adjusting the output welding gun to the appropriate position, let the output welding gun perform welding according to the actual welding requirements. During welding, the output of the gear output motor causes the steering output gear to rotate and drive the positioning belt to move, so as to perform ring welding on the display hanging rod that needs to be welded from different angles. Step Six: After welding at one position is completed, the movable base is moved to the corresponding welding position by adjusting the direction input rod to drive the movable hinge seat. Welding of the other end display hanging rod is then carried out. During the rotation and movement of the rotating bracket controlled by the output of the second drive motor, the steering output bracket will drive the movable connecting ring to move. The mounting plate will drive the preheating pipe, gas valve and gas guide pipe to rotate and move, which in turn causes the gas guide pipe to drive the ventilation frame to rotate and move. This movement will cause the partition plate to contact and rotate with the side wall of the protective chamber, so that the jet nozzle always faces the output welding gun.

[0016] The beneficial effects of this invention are: 1. By employing a multi-motor collaborative approach, this invention achieves "optimal flexibility" for specific tasks at a cost comparable to dedicated equipment, avoiding the high cost of dedicated equipment in existing technologies, reducing potential harm to workers caused by direct manual operation, and improving operational safety.

[0017] 2. This invention uses a gear-driven motor to drive a steering output gear, which in turn drives a control toothed belt on the outside of the positioning belt. This allows for welding of complex metal frames and metal display hanging rods of display cabinets during the welding process, offering greater flexibility and targeting, and solving the problem of both performance waste and insufficient capacity.

[0018] 3. This invention utilizes the working process of the second drive motor output to adjust the flipping bracket for flipping, so that the movement of the moving connecting ring drives the preheating pipe, thereby controlling the contact between the ventilation frame and the output welding torch with the protective chamber, so that the air nozzle on the outside of the cross bracket is directed towards the output welding torch, and the high-temperature gas generated during the welding process is discharged through the air intake, preventing problems such as excessive temperature inside the cabinet causing cabinet deformation, and ensuring welding quality.

[0031] A welding processing device and welding processing method for an intelligent display cabinet, such as Figure 1 As shown, the system includes a support mechanism 1. A first drive mechanism 2 for controlling the rotation of the welding direction is fixedly installed at the top of the support mechanism 1. A steering mechanism 3 for adjusting the welding output direction is movably installed at the front end of the first drive mechanism 2. A welding support mechanism 4 is fixedly installed inside the steering mechanism 3. A second drive mechanism 5 for further controlling the output direction is fixedly connected to the outside of the welding support mechanism 4. A flipping limit mechanism 6 for guiding the welding output direction is fixedly connected to the outside of the second drive mechanism 5. A welding output mechanism 7 for welding processing is fixedly connected to the end of the second drive mechanism 5 away from the welding support mechanism 4. A welding protection mechanism 8 for protecting the welding is fixedly connected to the outside of the welding output mechanism 7.

[0032] By controlling the support mechanism 1, the coarse position movement of the entire mechanism can be controlled. The first drive mechanism 2 is used to adjust the welding output angle during the welding process. The steering mechanism 3 is used to control the output direction during the welding process. The welding bracket mechanism 4 is used to control the welding direction before welding. The second drive mechanism 5 is used to control the welding output angle. The flipping limit mechanism 6 is used to provide a range limit for the angle adjustment during welding. The welding output mechanism 7 is used to perform welding processing. The welding protection mechanism 8 is used to protect the gas during the welding process.

[0033] like Figure 2 As shown, the support mechanism 1 includes a fixed support 11, a movable base 12 is fixedly connected to the bottom end of the fixed support 11, a movable hinge seat 13 is fixedly connected to the rear end of the movable base 12, a hinge tube 14 is rotatably connected to the inner side of the movable hinge seat 13, a direction input rod 15 is fixedly connected to the outer side of the hinge tube 14, and the direction input rod 15 is connected to the outer control mechanism.

[0034] The first drive mechanism 2 is directly supported by the fixed support 11. The direction input rod 15 is used to connect with the outer control mechanism. The direction input rod 15 controls the hinge tube 14, so that the movable hinge seat 13 drives the movable base 12 to move, thereby realizing the control of the first drive mechanism 2.

[0035] The first drive mechanism 2 includes a first drive motor 21. The output end of the first drive motor 21 passes through the fixed support 11 and is fixedly connected to a rotary bracket 22. A gear output motor 23 is fixedly connected to the outside of the rotary bracket 22. A steering output gear 24 is fixedly connected to the side wall of the gear output motor 23. A toothed belt bracket 25 is fixedly connected to the end of the rotary bracket 22 away from the support mechanism 1.

[0036] The first drive motor 21 outputs to the rotary support 22 to control the angle of the rotary support 22, which in turn controls the angle of the steering mechanism 3 connected to the toothed belt support 25. The gear output motor 23 outputs to control the steering output gear 24 to drive the steering mechanism 3 to move.

[0037] like Figure 3 As shown, the steering mechanism 3 includes a positioning belt 31, which is slidably connected to the inner side of the toothed belt bracket 25. A control toothed belt 32 is installed on the outer side of the positioning belt 31 at the position corresponding to the steering output gear 24. Toothed belt sealing plates 33 are fixedly connected to the two ends of the positioning belt 31 respectively. A mounting bracket 34 is fixedly connected to the end of the positioning belt 31 away from the first drive mechanism 2.

[0038] The control toothed belt 32 on the outer side of the positioning belt 31 is driven by the output of the steering output gear 24, which in turn controls the positioning belt 31 to move. During this movement, the mounting bracket 34 on the inner side of the positioning belt 31 drives the welding bracket mechanism 4 to move, thereby adjusting the welding angle and position during the welding process.

[0039] like Figure 4 As shown, the welding support mechanism 4 includes a fixed support 41, a fixed rotating shaft 42 fixedly connected to the outside of the fixed support 41, a limit baffle 43 fixedly connected to the top of the fixed support 41, a connecting fixed pipe 44 fixedly connected to the outside of the fixed support 41, and a limit flipping rod 45 rotatably connected to the outside of the fixed rotating shaft 42.

[0040] like Figure 5As shown, the second drive mechanism 5 includes a second drive motor 50, which is located outside the connecting and fixing pipe 44. The output end of the second drive motor 50 passes through the connecting and fixing pipe 44 and is fixedly connected to a second drive wheel 51. A second drive rod 52 is fixedly connected to the outside of the second drive wheel 51. An output flip ring 53 is fixedly connected to the end of the second drive rod 52 away from the second drive wheel 51. A flip bracket 54 is fixedly connected to the outside of the output flip ring 53. Active flip rings 55 are rotatably connected to both sides of the flip bracket 54. Active flip rods 56 with different directions are fixedly connected to the outside of the two active flip rings 55. Steering output brackets 57 are fixedly connected to the ends of the two active flip rods 56 away from the active flip rings 55. Two symmetrical steering driven rods 58 are rotatably connected to the outside of the steering output bracket 57. The active flip rods 56 and the steering driven rods 58 have the same length and form a rhombus. The steering driven rods 58 on both sides are rotatably connected to the same steering connecting bracket 59.

[0041] The second drive motor 50 drives the second drive rod 52 on the outside of the second drive wheel 51 to rotate, causing the output rotating ring 53 to rotate and drive the active rotating ring 55 to move. During the movement of the active rotating ring 55, the active rotating rod 56 provides the power for the movement of the steering output bracket 57, which drives the steering connecting bracket 59. This movement is limited by the limiting rotating rod 45 that is rotatably connected to the outside of the fixed rotating shaft 42.

[0042] like Figure 6 As shown, the flipping limiting mechanism 6 includes a limiting connecting frame 61, which is fixedly connected to the outside of the connecting fixing tube 44. A protective baffle 62 is fixedly connected to the outside of the limiting connecting frame 61. A limiting guide arc plate 63 is fixedly connected to the end of the limiting connecting frame 61 away from the connecting fixing tube 44. A guide groove 64 is provided on the inner side of the limiting guide arc plate 63.

[0043] The guide groove 64 on the outer side of the limiting guide arc plate 63 guides the movement of the steering connection bracket 59, so that the steering connection bracket 59 can always rotate and move within the range limited by the guide groove 64, thereby limiting the output direction of the welding output mechanism 7.

[0044] The welding output mechanism 7 includes a welding control head 71, which is fixedly connected to the outside of the steering connection bracket 59. A controller 72 is fixedly connected to the outside of the welding control head 71, and a display panel 73 is provided on the outside of the controller 72. An output welding torch 74 is fixedly connected to the end of the welding control head 71 away from the steering connection bracket 59, and a protective chamber 75 is fixedly connected to the outside of the output welding torch 74.

[0045] The welding output is controlled by the controller 72 on the outside of the welding control head 71, the display panel 73 is used for preset from the outside, the output welding torch 74 is responsible for outputting the welding arc, and the protective chamber 75 is used for gas protection during the welding process.

[0046] like Figure 7 As shown, the welding protection mechanism 8 includes two movable connecting rings 81. Both movable connecting rings 81 are located on the outside of the corresponding steering output bracket 57. The same movable guide bracket 82 is slidably connected to the outside of the two movable connecting rings 81. A lifting and rotating bracket 83 is fixedly connected to the end of the movable connecting ring 81 away from the second drive mechanism 5. The corresponding pipe bracket 84 is rotatably connected to the inside of the two lifting and rotating brackets 83. The same mounting plate 85 is rotatably connected to the two pipe brackets 84. A preheating pipe 86 is installed inside the mounting plate 85. The input end of the preheating pipe 86 is connected to an external gas tank. A gas valve 87 is installed at the output end of the preheating pipe 86. A gas guide pipe 88 is fixedly connected to the end of the gas valve 87 away from the preheating pipe 86. A venting frame 89 is connected to the end of the gas guide pipe 88 away from the gas valve 87. The ventilation frame 89 includes a half-pipe 891, a cross bracket 892 rotatably connected to the inner side of the half-pipe 891, the cross bracket 892 communicating with the air guide pipe 88, a partition plate 893 fixedly connected to the outer side of the cross bracket 892, a jet nozzle 894 opened at one end of the outer side of the cross bracket 892 corresponding to the protective chamber 75, and an air intake 895 opened on the outer side wall of the cross bracket 892 not corresponding to the protective chamber 75.

[0047] Protective gas, such as carbon dioxide or other inert gas, is supplied to the preheating pipe 86 from the outside to preheat the gas. The preheated gas is then depressurized by the gas valve 87. After controlling the gas pressure, the gas is supplied to the inside of the protective chamber 75 through the gas guide pipe 88. This allows the gas to protect the welding position, improving the safety of the welding process. It also provides a certain degree of protection for the welded display rods and cabinets.

[0048] A welding process for an intelligent display cabinet, performed by the aforementioned welding device for intelligent display cabinets, includes the following steps: Step 1: First, install the display hanging rods that need to be welded into the display case in the corresponding positions inside the display case, and fix the rods to be welded by means of adhesive or other methods. Then, according to the actual situation, select the corresponding positioning belt 31, and select the corresponding control tooth belt 32 on the outside of the positioning belt 31 according to the length and curvature. Then, install the fixing bracket 41 at the mounting bracket 34 position on the inside of the positioning belt 31 to complete the preparation work before welding. Step 2: After the preparation is completed, use the external control mechanism to control the direction input rod 15, adjust the height and position of the movable base 12 through the direction input rod 15, move the output welding gun 74 to the welding position, and then control the first drive motor 21 to output the angle of the rotating bracket 22, so that the output welding gun 74 is rotated to a position close to the display hanging rod that needs to be welded. Step 3: After completing the previous step, control the gear output motor 23 according to the actual welding angle required, so that the gear output motor 23 rotates through the steering output gear 24, adjusts the position of the positioning belt 31 inside the toothed belt bracket 25, and then controls the position of the mounting bracket 34, so that the angle of the output welding gun 74 can be adjusted. Step 4: After the adjustment in the previous step is completed, further control the output of the second drive motor 50 so that the output of the second drive motor 50 drives the second drive rod 52 to move, so that the output flip ring 53 drives the flip bracket 54 to flip the active flip ring 55 to the corresponding position. The movement of the active flip ring 55 will drive the active flip rod 56 on its outer side to move, so that the steering output brackets 57 on both sides move, causing the angle of the steering connecting bracket 59 to flip. When the steering connecting bracket 59 is driven by the steering driven rod 58, the steering connecting bracket 59 will move under the guidance of the guide groove 64 on the inner side of the limit guide arc plate 63, so as to further fine-tune the output angle of the output welding gun 74. Step 5: After adjusting the output welding gun 74 to the corresponding position, let the output welding gun 74 perform welding according to the actual welding requirements. During welding, the output of the gear output motor 23 causes the steering output gear 24 to rotate and drive the positioning belt 31 to move, so as to perform ring welding on the display hanging rod that needs to be welded from different angles. Step Six: After welding at one position is completed, the movable base 12 is moved to the corresponding welding position by adjusting the direction input rod 15 to drive the movable hinge seat 13, and welding of the other end display hanging rod is carried out. During the rotation and movement of the rotating bracket 54 controlled by the output of the second drive motor 50, the steering output bracket 57 will drive the movable connecting ring 81 to move. The mounting plate 85 will drive the preheating pipe 86, the air valve 87 and the air guide pipe 88 to rotate and move, which in turn causes the air guide pipe 88 to drive the ventilation frame 89 to rotate and move. This movement will cause the partition plate 893 to contact and rotate with the side wall of the protective chamber 75, so that the jet nozzle 894 always faces the output welding gun 74.

[0049] Since the jet nozzle 894 always points towards the output welding torch 74, the output welding torch 74 is always protected by the gas discharged from the jet nozzle 894. The gas absorbed by the suction port 895 will be introduced into the gas valve 87 through the gas guide pipe 88. The two ports of the gas valve 87 are respectively connected to the jet nozzle 894 and the suction port 895 inside the half-pipe 891 to realize jetting and suction respectively. This is intended to prevent the cabinet from being filled with high-temperature gas, causing the cabinet temperature to be too high and resulting in problems such as cabinet deformation. When the second drive motor 50 outputs and causes the flipping bracket 54 to flip, the movement of the steering output bracket 57 drives the moving connecting ring 81, which in turn moves the installation plate 85 to control the preheating pipe 86 and adjusts the position of the gas guide pipe 88. This also prevents the ventilation frame 89 from affecting the output welding torch 74 during the welding process, thus preventing any impact on the welding effect.

10. A welding process for an intelligent display cabinet, performed by the welding process apparatus for the intelligent display cabinet as described in claim 9, characterized in that, Includes the following steps: Step 1: First, install the display hanging rods that need to be welded into the display cabinet in the corresponding positions inside the display cabinet, and fix the rods that need to be welded by means of adhesive or other methods. Then, according to the actual situation, select the corresponding positioning belt (31), and select the corresponding control tooth belt (32) on the outside of the positioning belt (31) according to the length and curvature. Then, install the fixing bracket (41) at the mounting bracket (34) position on the inside of the positioning belt (31) to complete the preparation work before welding. Step 2: After the preparation work is completed, use the external control mechanism to control the direction input rod (15), adjust the height and position of the movable base (12) through the direction input rod (15), move the output welding gun (74) to the welding position, and then control the first drive motor (21) to output the angle of the rotating bracket (22) to rotate the output welding gun (74) to the position close to the display hanging rod that needs to be welded; Step 3: After completing the previous step, control the gear output motor (23) according to the actual welding angle required, so that the gear output motor (23) rotates through the steering output gear (24) to adjust the position of the positioning belt (31) inside the toothed belt bracket (25), thereby controlling the position of the mounting bracket (34) and adjusting the angle output of the output welding gun (74); Step 4: After the adjustment in the previous step is completed, further control the output of the second drive motor (50) so that the output of the second drive motor (50) drives the second drive rod (52) to move, so that the output flip ring (53) drives the flip bracket (54) to flip the active flip ring (55) to the corresponding position.
