DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1: Figure 1-Figure 5 , Figure 8 and Fig. 9 As shown, the intelligent welding device for processing tea sieve frames includes a frame 100, a storage rotating mechanism 110, four sets of sieve supporting mechanisms 120, a pressing mechanism 130 and a welding mechanism 140.

[0024] The object-placing rotating mechanism 110 is installed on the frame 100, and includes a housing 111, a top plate 112, a clamping frame assembly, and a driving assembly. The housing 111 is rotatably connected to the frame 100; the top plate 112 is installed on the top surface of the housing 111; the clamping frame assembly is slidably connected to the top plate 112, and the clamping frame assembly is used to clamp and fix the fixed frames 200 of different sizes; the driving assembly is used to drive the housing 111 to rotate.

[0025] The four groups of screen supporting mechanisms 120 can be detachably installed on the top plate 112, and the screen supporting mechanism 120 is used to support the sieve plate 201; the pressing mechanism 130 is installed on the inner top surface of the frame 100, and the pressing mechanism 130 is used to press the sieve plate 201 so that the top surface height of the sieve plate 201 is the same as the top surface height of the fixed frame 200; the welding mechanism 140 is installed on the inner top surface of the frame 100, and the welding mechanism 140 is used to weld the sieve plate 201 and the fixed frame 200.

[0026] Specifically, the clamping frame assembly is adjusted to match the diameter of the fixing frame 200 to be welded, and then the fixing frame 200 to be welded is placed on the clamping frame assembly.

[0027] Then, the sieve plate 201 to be welded is placed on four sets of screen supporting mechanisms 120, and then the pressing mechanism 130 is started to press the sieve plate 201 downward so that the top surface height of the sieve plate 201 is the same as the top surface height of the fixed frame 200, thereby facilitating welding of the fixed frame 200 and the sieve plate 201.

[0028] Then, the welding mechanism 140 is started to weld the sieve plate 201 and the fixed frame 200. During welding, the driving assembly is started to drive the shell 111, the top plate 112, the clamping frame assembly and the screen supporting mechanism 120 to rotate, thereby driving the fixed frame 200 and the sieve plate 201 to rotate, so that the welding mechanism 140 welds other positions of the fixed frame 200 and the sieve plate 201.

[0029] like Figure 4-Figure 7 As shown, the object placement rotating mechanism 110 further includes a plurality of through slots 1121, four fixing blocks 113 and a plurality of guide members 114. The plurality of through slots 1121 are all formed through the top plate 112; the four fixing blocks 113 are all installed on the top surface of the top plate 112; and the plurality of guide members 114 are all installed on the bottom surface of the top plate 112.

[0030] like Figure 6 and Figure 7 As shown, the clamping frame assembly includes a plurality of frame supporting members 115 , a plurality of rotating shafts 116 , a plurality of gear columns 1161 , a first motor 117 and a first gear 1171 .

[0031] The plurality of frame support members 115 are respectively slidably connected with the plurality of through slots 1121 and the plurality of guide members 114; the frame support member 115 comprises a moving plate 1151, a frame support slot 1152, a slide slot 1153 and a tooth plate 1154. The moving plate 1151 is arranged in an "L" shape, and the moving plate 1151 passes through the through slot 1121 and is slidably connected with the through slot 1121; the frame support slot 1152 is provided on the top surface of the moving plate 1151, and the frame support slot 1152 is used to place the fixed frame 200; the slide slot 1153 is provided on the bottom surface of the moving plate 1151, and the slide slot 1153 is slidably connected with the guide member 114; the tooth plate 1154 is installed on the moving plate 1151, and the tooth plate 1154 is meshed and connected with the gear column 1161.

[0032] Multiple rotating shafts 116 are rotatably connected to the bottom surface of the top plate 112; multiple gear columns 1161 are respectively fixedly mounted on the multiple rotating shafts 116; the first motor 117 is installed on the inner bottom surface of the shell 111; the first gear 1171 is installed on the power output shaft of the first motor 117, and the first gear 1171 is meshingly connected with the multiple gear columns 1161.

[0033] Specifically, when the first motor 117 is running, it will drive the first gear 1171 to rotate, and then mesh with and drive the multiple gear columns 1161 to rotate. Since the tooth plate 1154 on the support frame member 115 is meshed and connected with the gear column 1161, when the gear column 1161 rotates, the tooth plate 1154 will drive the movable plate 1151 to move along the through groove 1121 and the guide member 114, so that the multiple movable plates 1151 move toward the center position of the top plate 112 at the same time, or move to a position away from the center of the top plate 112 at the same time; thereby, the multiple movable plates 1151 can support fixed frames 200 of different diameters.

[0034] like Figure 4 and Figure 8 As shown, the driving assembly includes a second motor 118, a second gear 1181 and a gear ring 119. The second motor 118 is mounted on the inner bottom surface of the frame 100; the second gear 1181 is mounted on the power output shaft of the second motor 118; the gear ring 119 is fixedly sleeved on the housing 111, and the gear ring 119 is meshed and connected with the second gear 1181.

[0035] Specifically, when the second motor 118 is running, it drives the second gear 1181 to rotate, which in turn engages and drives the gear ring 119 to rotate, thereby driving the housing 111 to rotate.

[0036] like Figure 4 and Figure 8 As shown, the screen supporting mechanism 120 includes a cylinder 121, a mounting block 122, a socket 123, a telescopic rod 124, a support plate 125 and a spring 126. The top of the cylinder 121 is open; the mounting block 122 is rotatably connected to the bottom surface of the cylinder 121, and a groove for plugging and matching with the fixed block 113 is provided on the bottom surface of the mounting block 122; the socket 123 is provided on the mounting block 122; the telescopic rod 124 is installed in the cylinder 121; the support plate 125 is fixedly connected to the extended end of the telescopic rod 124; one end of the spring 126 is fixedly connected to the bottom surface of the support plate 125, and the other end of the spring 126 is fixedly connected to the inner bottom surface of the cylinder 121.

[0037] Specifically, by placing the sieve plate 201 on the top surfaces of multiple support plates 125, the springs 126 will lift the sieve plate 201 through the support plates 125. When the sieve plate 201 is pressed downward, the support plates 125 will be squeezed and the springs 126 will be compressed.

[0038] like Figure 1-Figure 3 and Fig. 9 As shown, the pressing mechanism 130 includes a first hydraulic cylinder 131 and a pressing plate 132. The first hydraulic cylinder 131 is mounted on the inner top surface of the frame 100; the pressing plate 132 is rotatably mounted on the extended end of the first hydraulic cylinder 131.

[0039] Specifically, by starting the first hydraulic cylinder 131, the pressing plate 132 is driven to move downward, so that the pressing plate 132 contacts the sieve plate 201 and presses the sieve plate 201. Since the pressing plate 132 is rotatably connected to the first hydraulic cylinder 131, when the pressing plate 132 presses the sieve plate 201, the rotation of the sieve plate 201 is not affected.

[0040] like Figure 1-Figure 3 and Fig. 9 As shown, the welding mechanism 140 includes a moving seat 141, a linear drive assembly 142, a multi-stage hydraulic cylinder 143 and a welding machine 144. The linear drive assembly 142 is used to drive the moving seat 141 to move horizontally; the linear drive assembly 142 includes a box body with an opening at the bottom, a drive motor is installed on one side of the box body, a lead screw is installed on the power output shaft of the drive motor, the lead screw extends into the box body and is rotatably connected to the box body, a lead screw nut is sleeved on the part of the lead screw located in the box body, the lead screw nut penetrates the moving seat 141 and is fixedly connected to the moving seat 141, and the moving seat 141 is slidably connected to the box body. When the drive motor is running, it will drive the lead screw to rotate, thereby moving the lead screw nut, and then driving the moving seat 141 to move horizontally.

[0041] The multi-stage hydraulic cylinder 143 is installed on the inner top surface of the frame 100, and the extending end of the multi-stage hydraulic cylinder 143 is fixedly connected to the top surface of the box body in the linear drive assembly 142. The welding machine 144 is installed on the top surface of the box body of the linear drive assembly 142, and the welding head 145 of the welding machine 144 is installed on the moving seat 141.

[0042] Specifically, by starting the linear drive component 142, the position of the movable seat 141 is adjusted, and then the position of the welding head 145 is adjusted, so that the welding head 145 is directly above the connection between the fixed frame 200 and the sieve plate 201, and then by starting the multi-stage hydraulic cylinder 143, the distance between the welding head 145 and the sieve plate 201 is adjusted. Finally, the welding machine 144 is started to weld the fixed frame 200 and the sieve plate 201 through the welding head 145.

[0043] Working principle: When in use, first adjust the distance between the multiple movable plates 1151 and the center position of the top plate 112 according to the diameter of the fixed frame 200 to be welded. The specific operation is to start the first motor 117 to drive the first gear 1171 to rotate, and then engage and drive the multiple gear columns 1161 to rotate. Since the tooth plate 1154 on the support frame 115 is engaged with the gear column 1161, when the gear column 1161 rotates, the movable plate 1151 will be driven to move along the through groove 1121 through the tooth plate 1154, so that the multiple movable plates 1151 are simultaneously moved to the center position of the top plate 112, or simultaneously moved to a position away from the center of the top plate 112, thereby adjusting the positions of the multiple movable plates 1151.

[0044] After the adjustment is completed, the fixing frame 200 is placed in a plurality of support frame grooves 1152 , and then the sieve plate 201 to be welded is placed on a plurality of support plates 125 .

[0045] Then, by starting the first hydraulic cylinder 131 , the pressing plate 132 is driven to move downward, so that the pressing plate 132 contacts the sieve plate 201 and presses the sieve plate 201 , so that the top surface height of the sieve plate 201 is the same as the top surface height of the fixing frame 200 .

[0046] Then, by starting the linear drive component 142, the position of the movable seat 141 is adjusted, and then the position of the welding head 145 is adjusted, so that the welding head 145 is directly above the connection between the fixed frame 200 and the sieve plate 201, and then by starting the multi-stage hydraulic cylinder 143, the distance between the welding head 145 and the sieve plate 201 is adjusted. Finally, the welding machine 144 is started to weld the fixed frame 200 and the sieve plate 201 through the welding head 145.

[0047] During welding, by starting the second motor 118, the second gear 1181 is driven to rotate, which in turn engages and drives the gear ring 119 to rotate, which in turn drives the shell 111 to rotate, and then drives the top plate 112, the clamping frame assembly and the screen supporting mechanism 120 to rotate, and then drives the fixed frame 200 and the sieve plate 201 to rotate, so that the welding head 145 can weld other positions of the fixed frame 200 and the sieve plate 201.

[0048] Example 2: Fig.10 and Fig.11 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: The intelligent welding device for processing tea sieve frames also includes four supporting legs 101 , four widening blocks 102 and four inserting rods 103 .

[0049] The four supporting legs 101 are all installed on the bottom surface of the frame 100; the four widening blocks 102 are respectively installed on the four supporting legs 101, and the widening blocks 102 are plugged into the grooves of the mounting blocks 122; the four plug rods 103 are respectively plugged into the four widening blocks 102, and the plug rods 103 are plugged into the sockets 123.

[0050] Working principle: When the device needs to be moved, the four supporting screen mechanisms 120 are separated from the four fixed blocks 113 respectively, and then the four inserting rods 103 are separated from the four widening blocks 102; Then, by plugging the groove on the mounting block 122 into the widening block 102 and then using the insertion rod 103 to penetrate the insertion hole 123, the mounting block 122 and the widening block 102 are connected together, and the above operation is repeated to connect four mounting blocks 122 to four widening blocks 102 respectively.

[0051] Thereby, the supporting legs 101 are separated from the ground, the four cylinders 121 are in contact with the ground, and the four cylinders 121 serve as temporary moving wheels, thereby facilitating the movement of the frame 100 and improving the applicability of the device.

[0052] Example 3: Figure 1-Figure 9 The method for using the intelligent welding device for processing tea sieve frames comprises the following steps: Step 1: According to the diameter of the fixed frame 200 to be welded, adjust the distance between the multiple movable plates 1151 and the center position of the top plate 112 to make the size of the clamping frame assembly match the size of the fixed frame 200 to be welded; Step 2: Place the fixed frame 200 on the adjusted clamping frame assembly, ensure that the fixed frame 200 is firmly placed in the plurality of support frame slots 1152, and then place the sieve plate 201 to be welded on the support plates 125 of the four groups of support screen mechanisms 120; Step 3: Start the first hydraulic cylinder 131 to drive the pressing plate 132 to move downward. The pressing plate 132 moving downward will contact the sieve plate 201 and squeeze the sieve plate 201 so that the top surface height of the sieve plate 201 is the same as the top surface height of the fixed frame 200. Step 4: Start the linear drive assembly 142 to horizontally adjust the position of the movable seat 141, and then adjust the position of the welding head 145 so that the welding head 145 is directly above the connection between the fixed frame 200 and the sieve plate 201; Step 5: Start the multi-stage hydraulic cylinder 143 to drive the linear drive assembly 142 and the moving seat 141 to move downward, thereby adjusting the distance between the welding head 145 and the sieve plate 201 to ensure accuracy and safety during the welding process; Step 6: Start the welding machine 144 and weld the fixing frame 200 and the sieve plate 201 through the welding head 145; Step seven: During the welding process, the second motor 118 of the driving assembly is started to drive the second gear 1181 to rotate, and then the gear ring 119 is engaged to rotate, thereby driving the shell 111, the top plate 112, the clamping frame assembly and the screen supporting mechanism 120 to rotate. The rotation of the shell 111 will drive the fixed frame 200 and the sieve plate 201 to rotate, so that the welding head 145 can weld other positions of the fixed frame 200 and the sieve plate 201.
