Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please refer to Figures 1-4 This utility model provides an automatic copper tube feeding device, including a working platform 101, a stepping conveyor mechanism, a copper tube storage mechanism, and a robotic arm mechanism; the stepping conveyor mechanism includes a fixed bracket 102, a stepping movable frame 103, a first movable plate 104, a second movable plate 105, and a stepping transmission assembly 106; the copper tube storage mechanism includes a storage box 107 and a copper tube conveying assembly 108; The working platform 101 is provided with a first clearance notch 1001, and the fixed bracket 102 is mounted on the first clearance notch 1001; the fixed end of the stepper transmission assembly 106 is disposed on the bottom surface of the working platform 101; the driving end of the stepper transmission assembly 106 extends out from the first clearance notch 1001 and is connected to the stepper movable frame 103; the fixed bracket 102 is located below the stepper movable frame 103; an assembly gap is formed between the first movable plate 104 and the second movable plate 105; the fixed bracket 102 is located in the assembly gap, that is, the first movable plate 104 and the second movable plate 105 are respectively disposed on both sides of the fixed bracket 102. The fixed bracket 102 is provided with multiple fixed placement notches 1002 spaced apart along the X-axis direction, and the stepping movable frame 103 is provided with multiple movable placement notches 1003. The stepping transmission component 106 is used to drive the stepping movable frame 103 to move, so that the movable placement notch 1003 drives the copper tube to be processed to move to the next fixed placement notch 1002. The storage bin 107, copper tube conveying assembly 108, and robotic arm mechanism are respectively disposed on the working platform 101. The storage bin 107 is located at the feeding end of the stepping conveyor mechanism; the copper tube conveying assembly 108 is disposed on the storage bin 107; and the robotic arm mechanism is located at the discharging end of the stepping conveyor mechanism. The storage bin 107 is used to place the copper tubes to be processed, and the copper tube conveying assembly 108 is used to transfer the copper tubes to be processed in the storage bin 107 to the movable placement notch 1003 of the stepping movable frame 103. The robotic arm mechanism is used to transfer the copper tubes to be processed to the equipment of the next process.

[0020] The movable placement notch 1003 is used to place the copper tube to be processed. The copper tube conveying assembly 108 pushes the copper tube to be processed out of the storage box 107, and the first movable placement notch 1003 on the stepping movable frame 103 catches the copper tube to be processed. The stepping transmission assembly 106 drives the stepping movable frame 103 to move. Through the cooperation of the movable placement notch 1003 and the fixed placement notch 1002, the copper tube to be processed is conveyed step by step. The conveying process is stable, realizing the automatic feeding and conveying of copper tubes.

[0021] The distance between the movable placement notches 1003 is the same as the distance between the fixed placement notches 1002. The stepping conveyor mechanism can accurately convey the copper tube to the clamping area of ​​the robotic arm mechanism according to a preset step length and rhythm. When the robotic arm mechanism grasps the copper tube to be processed, the copper tube needs to be in an accurate position. The stepping conveyor mechanism can ensure the positional accuracy of each conveying, enabling the robotic arm mechanism to reliably clamp the copper tube and avoid the inability of the robotic arm mechanism to properly transfer the copper tube to the next process equipment due to conveying position deviation. The step length is determined by the distance between adjacent movable placement notches 1003.

[0022] The automatic copper tube feeding device, through the cooperation of the fixed bracket 102, the stepping movable frame 103, the stepping transmission component 106 and the robotic arm mechanism, can realize the continuous conveying of copper tubes to be processed. In addition, the robotic arm mechanism transfers the copper tubes to be processed to the clamping mechanism of external equipment, forming an automated feeding process and improving the overall production efficiency.

[0023] Compared to manual conveying, the above structure has better continuity and stability, which can reduce problems such as inconsistent speed and pauses caused by manual operation, ensure efficient production, solve the problems of high labor intensity and unstable copper tube feeding rhythm in existing technologies, and improve copper tube feeding efficiency.

[0024] Specifically, the stepper drive assembly 106 includes an X-axis drive device 161, a support plate 162, and a Z-axis drive device 163. The fixed end of the X-axis drive device 161 is disposed on the bottom surface of the work platform 101, and the movable end of the X-axis drive device 161 faces the storage bin 107. The support plate 162 is disposed on the movable end of the X-axis drive device 161. The fixed end of the Z-axis drive device 163 is disposed on the support plate 162, and the movable end of the Z-axis drive device 163 is upwardly positioned. The stepper movable frame 103 is disposed on the movable end of the Z-axis drive device 163.

[0025] When copper pipe conveying is not in progress, the first movable placement notch 1003 of the stepping frame 103 is precisely aligned with the first fixed placement notch 1002 on the fixed bracket 102 in the X-axis direction. At this time, the position of the stepping frame 103 is the initial position. When the first movable placement notch 1003 is offset from the first fixed placement notch 1002 by a distance unit, and the horizontal height of the movable placement notch 1003 is the same as that of the fixed placement notch 1002, the position of the stepping frame 103 is the pipe connection position.

[0026] When copper tube conveying is required, the X-axis drive device 161 drives the stepping movable frame 103 to move towards the storage box 107. At the same time, the Z-axis drive device 163 drives the stepping movable frame 103 downward, so that the horizontal height of the movable placement notch 1003 is lower than that of the fixed placement notch 1002. Subsequently, the X-axis drive device 161 continues to drive the stepping movable frame 103 to move towards the storage box 107, and the Z-axis drive device 163 drives the stepping movable frame 103 upward, so that the stepping movable frame 103 changes from the initial position to the tube insertion position. At this time, the copper tube storage mechanism lifts the copper tube to be processed before the stepping movable frame 103 is in the tube insertion position. When the stepping movable frame 103 is in the tube insertion position, the first movable placement notch 1003 receives the copper tube to be processed. Next, the Z-axis drive device 163 drives the stepping movable frame 103 to move upward, so that the horizontal height of the movable placement notch 1003 is higher than that of the fixed placement notch 1002. The X-axis drive device 161 drives the stepping movable frame 103 to move away from the storage box 107 by one interval length unit. Then, the Z-axis drive device 163 drives the stepping movable frame 103 to move downward, placing the copper tube to be processed on the first fixed placement notch 1002.

[0027] The process of the stepping movable frame 103 changing from the initial position to the pipe receiving position and then back to the initial position is one stepping cycle. Through multiple stepping cycles, the copper tube to be processed can be moved to the next fixed placement gap 1002 by cooperating with multiple movable placement gaps 1003, thereby achieving the effect of stepping conveying of the copper tube to be processed.

[0028] The interval between adjacent movable placement notches 1003 is the same as the interval between adjacent fixed placement notches 1002, both being one interval length unit. Therefore, the copper tube to be processed moves by one interval length unit each time.

[0029] Specifically, the robotic arm mechanism includes a robotic arm support 109, a Y-axis moving device 110, a Z-axis moving device 111, a rotating device 112, and a clamping device 113; The robotic arm support 109 is mounted on the work platform 101. The fixed end of the Y-axis moving device 110 is mounted on the robotic arm support 109. The fixed end of the Z-axis moving device 111 is mounted on the driving end of the Y-axis moving device 110. The fixed end of the rotating device 112 is mounted on the driving end of the Z-axis moving device 111. The clamping device 113 is mounted on the driving end of the rotating device 112. The clamping device 113 is used to clamp the copper tube to be processed.

[0030] The Y-axis moving device 110 and Z-axis moving device 111 can refer to existing linear motion modules, consisting of components such as a motor, linear guide rail, and ball screw. The rotational motion of the motor is converted into linear motion through the cooperation of the screw, nut, and balls. The rotating device 112 can refer to existing rotary motors. The Y-axis moving device 110 drives the Z-axis moving device 111, the rotating device 112, and the clamping device 113 to move along the Y-axis, while the Z-axis moving device 111 drives the rotating device 112 and the clamping device 113 to move along the Z-axis. The rotating device 112 drives the clamping device 113 to rotate, thereby changing the angle of the copper tube to be processed.

[0031] With the above structure, the Y-axis moving device 110 can drive the copper tube to be processed to move horizontally, the Z-axis moving device 111 can drive the copper tube to be processed to move vertically, and the rotating device 112 is used to adjust the direction of the copper tube to be processed, so that the robotic arm mechanism can perform multi-degree-of-freedom movement. By adjusting the position and angle of the copper tube to be processed, the copper tube to be processed can be transferred from the fixed placement notch 1002 to the clamping device of the next process equipment.

[0032] Specifically, the clamping device 113 includes a gripper cylinder 131, a first gripper arm 132, and a second gripper arm 133; the fixed end of the gripper cylinder 131 is located at the driving end of the rotating device 112, and the gripper cylinder 131 has two gripper driving ends. One end of the first gripper arm 132 is connected to one gripper driving end, and one end of the second gripper arm 133 is connected to the other gripper driving end; the other end of the first gripper arm 132 and the other end of the second gripper arm 133 cooperate to form a copper tube clamping station.

[0033] The gripper cylinder 131 drives the two gripper drive ends to move closer or further apart, thereby achieving the purpose of clamping or releasing the copper tube to be processed by the first gripper arm 132 and the second gripper arm 133. This structure provides a stable and adjustable clamping force. During copper tube processing or handling, different specifications of copper tubes require different clamping forces. The gripper cylinder 131 can adjust the air pressure according to actual needs, thereby precisely controlling the clamping force and ensuring that the copper tube will not slip due to insufficient force, nor will its surface be damaged due to excessive force.

[0034] Specifically, the fixed bracket 102 includes a bracket body 121 and a support groove 122. The bracket body 121 is mounted on the first clearance notch 1001 along the X-axis direction, and the support groove 122 is disposed on the top surface of the bracket body 121. The fixed placement notch 1002 is spaced apart on the top of the support groove 122. The stepping movable frame 103 is located below the bracket body 121, and the maximum Z-axis movement range of the stepping movable frame 103 is lower than that of the bracket body 121. The first movable plate 104 is disposed on one side of the stepping movable frame 103 in the Y-axis direction, and the second movable plate 105 is disposed on the other side of the stepping movable frame 103.

[0035] The stepping frame 103 is located below the support body, and the maximum Z-axis movement range of the stepping frame 103 is lower than that of the support body 121. This avoids interference between the stepping frame 103 and the support body 121 during the copper tube conveying process, which would prevent the copper tube to be processed from being conveyed by stepping.

[0036] Specifically, the storage bin 107 has a accommodating space, and the bottom of the accommodating space has a copper tube lifting notch 170 arranged along the Y-axis direction. The copper tube lifting notch 170 has inclined surfaces on both sides. The width of the copper tube lifting notch 170 is adapted to the diameter of the copper tube to be processed. The working platform 101 has a second clearance notch 1004 adapted to the copper tube lifting notch 170. The storage bin 107 is arranged above the second clearance notch 1004. The driving end of the copper tube conveying assembly 108 passes through the second clearance notch 1004 and the copper tube lifting notch 170 in sequence and extends into the accommodating space.

[0037] With the above structure, inclined surfaces are provided on both sides of the copper pipe lifting notch 170. The copper pipe to be processed placed in the accommodating space is affected by gravity and can move towards the copper pipe lifting notch 170, so that the copper pipe to be processed can be moved to the driving end of the copper pipe conveying assembly 108. Since the width of the copper pipe lifting notch 170 is matched with the diameter of the copper pipe to be processed, the copper pipe conveying assembly 108 can accurately lift the isolated copper pipe.

[0038] The storage bin 107 utilizes gravity and mechanical geometric constraints to achieve orderly material distribution, precise positioning, and reliable conveying, thereby improving automation and reliability and reducing the risk of material jamming.

[0039] Preferably, the inner wall of the storage bin 107 is provided with a width adjustment unit, which includes a first sliding rod 171, a second sliding rod 172, a first limiting plate 173, and a second limiting plate 174. The first sliding rod 171 and the second sliding rod 172 are arranged side by side in the storage bin 107 along the Y-axis direction. One end of the first limiting plate 173 is slidably mounted to the first sliding rod 171, and the other end of the first limiting plate 173 is slidably mounted to the second sliding rod 172. One end of the second limiting plate 174 is slidably mounted to the first sliding rod 171, and the other end of the second limiting plate 174 is slidably mounted to the second sliding rod 172. The driving end of the copper tube conveying assembly 108 is located between the first limiting plate 173 and the second limiting plate 174. The bottom shapes of the first limiting plate 173 and the second limiting plate 174 are adapted to the bottom shape of the accommodating space. The bottom of the first limiting plate 173 and the second limiting plate 174 both extend downward to limit protrusions 175, which are embedded in the copper tube lifting notch 170.

[0040] One end of the first sliding rod 171 is disposed on the inner wall of the storage bin 107 at one end in the Y-axis direction, and the other end of the first sliding rod 171 is disposed on the inner wall of the storage bin 107 at the other end in the Y-axis direction; one end of the second sliding rod 172 is disposed on the inner wall of the storage bin 107 at one end in the Y-axis direction, and the other end of the second sliding rod 172 is disposed on the inner wall of the storage bin 107 at the other end in the Y-axis direction; the first sliding rod 171 is located on the side of the storage bin 107 closer to the stepping conveyor mechanism, and the second sliding rod 172 is located on the side of the storage bin 107 away from the stepping conveyor mechanism.

[0041] The above structure, through the cooperation of the first limiting plate 173, the second limiting plate 174 and the inner wall of the storage box 107, plays a constraining role for the copper tube to be processed.

[0042] Staff can adjust the spacing between the first limiting plate 173 or the second limiting plate 174 according to the actual situation to perfectly accommodate copper pipes of different lengths. For shorter copper pipes, the spacing can be reduced to prevent them from lying horizontally or tilting inside the box; for longer copper pipes, the spacing can be increased to ensure that they can be smoothly placed and lowered.

[0043] Further, the copper tube conveying assembly 108 includes a connecting plate 181, a lifting device 182, and a lifting rod 183; the connecting plate 181 is disposed in the storage box 107, the connecting plate 181 passes through the second clearance notch 1004 and extends into the lower part of the working platform 101, the fixed end of the lifting device 182 is disposed in the connecting plate 181; the driving end of the lifting device 182 is connected to the lifting rod 183; the lifting rod 183 passes through the second clearance notch 1004 and the copper tube lifting notch 170, and enters the accommodating space, and the position of the lifting rod 183 is adapted to the stepping movable frame 103; the top of the lifting rod 183 is provided with a groove 1005 adapted to the diameter of the copper tube to be measured, and the lifting device 182 is used to drive the lifting rod 183 to move along the Z-axis direction.

[0044] The groove 1005 is positioned along the Y-axis, and the lifting rod 183 is located between the X-axis extension lines of the first fixed bracket 102 and the X-axis extension lines of the second fixed bracket 102. Before conveying the copper tube to be processed, the top of the lifting rod 183 is located in the copper tube lifting notch 170, and one of the copper tubes to be processed is embedded in the groove 1005. When it is necessary to convey the copper tube to be processed, the lifting device 182 drives the lifting rod 183 to move upward, and the copper tube to be processed is lifted by the lifting rod 183, so that the copper tube to be processed can approach the stepping movable frame 103, thereby allowing the first movable placement notch 1003 to receive the copper tube to be processed. The lifting device 182 is a cylinder.

[0045] Furthermore, the copper tube conveying assembly 108 also includes a slide rail plate 184, a first slide rail 185, a first slider 186, a second slide rail 187, and a second slider 188; The slide rail plate 184 is connected to the drive end of the lifting device 182. The first slide rail 185 is arranged on one side of the slide rail plate 184 along the Y-axis direction. The first slider 186 is slidably mounted on the first slide rail 185. The lifting rod 183 is fixed to the first slider 186. The second slide rail 187 is arranged on the connecting plate 181 along the Z-axis direction. The second slider 188 is arranged on one side of the slide rail plate 184. The second slider 188 is slidably mounted on the second slide rail 187.

[0046] With the above structure, the position of the lifting rod 183 in the Y-axis direction can be adjusted through the cooperation of the first slide rail 185 and the first slider 186, allowing the lifting rod 183 to move to the middle of the copper tube to be processed. This prevents the copper tube from falling due to weight imbalance at both ends when the lifting rod 183 is lifted. By cooperating with the width adjustment unit, the automatic copper tube feeding device can process copper tubes of different lengths, improving its adaptability.

[0047] In one specific embodiment of this utility model, two first slide rails 185, two lifting rods 183, four first sliders 186, two second slide rails 187, and two second sliders 188 are provided. The two first slide rails 185 are arranged side by side, and each lifting rod 183 is provided with two first sliders 186. The upper first slider 186 is slidably assembled with the upper first slide rail 185, and the lower first slider 186 is slidably assembled with the lower first slide rail 185. The two second slide rails 187 are respectively located at both ends of the connecting plate 181 in the Y-axis direction, and the second sliders 188 are located at both ends of the slide rail plate 184 in the Y-axis direction. This structure makes the copper tube to be processed more stable during the lifting process.
