Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field.

[0035] See also Figure 1 The schematic diagram of the workpiece supplied by the heat shrink tube feeding device of the present invention includes a first terminal 101 , a second terminal 102 , a third terminal 103 and an outer tube 100 sleeved on the first terminal 101 , the second terminal 102 , and the third terminal 103 .

[0036] See also Figures 2 to 9 An embodiment of a heat shrink tubing feeding device according to the present invention is shown, comprising a terminal feeding mechanism 2, an outer tube feeding mechanism 3, and a clamping mechanism 1. The two terminal feeding mechanisms 2 are positioned opposite each other, respectively feeding a first terminal and a second terminal, while the outer tube feeding mechanism 3 is used to feed an outer tube. The clamping mechanism 1 is positioned between the two terminal feeding mechanisms 2 and includes at least one clamping portion 11.

[0037] The clamping portion 11 includes an outer clamping portion 111 and an inner clamping portion 112 that are nested. The outer clamping portion 111 is provided with a first terminal accommodating cavity 1111 and a second terminal accommodating cavity 1112 that respectively accommodate the first terminal and the second terminal. The outer clamping portion 111 realizes synchronous clamping and release of the first terminal and the second terminal through a second driving component 113. The inner clamping portion 112 is arranged between the first terminal accommodating cavity 1111 and the second terminal accommodating cavity 1112, and an outer tube accommodating cavity is provided inside the inner clamping portion 112. The inner clamping portion 112 realizes clamping and release of the outer tube through a third driving component 114.

[0038] As a further optimization of this embodiment, the second drive component 114 and the first drive component 12113 are both left and right moving cylinders, and correspondingly the outer clamping part 111 and the inner clamping part 112 are both configured to be openable or closed along the direction of the left and right moving cylinders.

[0039] The outer tube feeding mechanism 3 includes an outer tube feeding channel 3 , and a robot 4 for grabbing the outer tube into the outer tube accommodating cavity is provided above the outer tube feeding channel 3 .

[0040] In the working state, the terminals are transported to the clamping mechanism 1 in the middle through two symmetrically distributed terminal feeding mechanisms 2, and the outer tube of the outer tube feeding mechanism 3 is transported to the clamping mechanism 1 by the robot 4 to complete the automated loading work. After the outer tube feeding and the terminal feeding, the overall clamping of multiple parts of the heat shrink tube is realized, which facilitates the full automation of processing and production and improves work efficiency.

[0041] In this embodiment, the outer clamping portion 111 further includes a third terminal accommodating cavity 1113 for accommodating a third terminal. The third terminal accommodating cavity 1113 is located between the first terminal accommodating cavity 1111 and the outer tube accommodating cavity. The outer clamping portion 111 synchronously clamps and releases the third terminal via a second drive assembly 113. This allows three terminals to be simultaneously held and threaded on the same clamping portion 11, significantly improving production efficiency compared to conventional solutions.

[0042] Specifically, a terminal opening is provided at the top of the outer clamping portion 111, communicating with the third terminal accommodating cavity 1113. The terminal opening is arranged vertically upward, and the third terminal enters the third terminal accommodating cavity 1113 through the terminal opening. This changes the input of the various parts from horizontal to horizontal plus vertical, allowing multiple parts to be clamped and assembled simultaneously, greatly improving production efficiency.

[0043] In this embodiment, a cylinder group is preferably used to drive the manipulator 4 vertically and horizontally, which is more responsive, safer and more reliable. The manipulator 4 is used to grab the outer tube and place it into the outer tube receiving cavity, which saves more space and can be carried out simultaneously with the terminal feeding, thereby improving production efficiency.

[0044] As a further optimization of this embodiment, a temporary storage portion 7 for accommodating the third terminal is provided on one side of the top end of the outer tube feed channel. The temporary storage portion 7 is driven and connected to a fourth drive assembly 71 for pushing the temporary storage portion 7 toward the outer tube feed channel. The manipulator 4 is configured to simultaneously grasp / release the outer tube and the third terminal. Specifically, the manipulator 4 is provided with an outer tube clamp for clamping the outer tube and a terminal clamp for clamping the third terminal. Cylinder clamping or vacuum adsorption can be used. The present invention does not specifically limit the clamping method. By arranging the manipulator 4 to grasp / release the outer tube and the third terminal at the same time, the outer tube and the third terminal can be simultaneously loaded into the clamping mechanism 1, thereby improving production efficiency.

[0045] Specifically, the manipulator 4 is mounted on a fifth drive assembly, which includes a first cylinder 51 that extends horizontally toward the clamping portion 11 and a second cylinder 52 that is drivably connected to the first cylinder and capable of reciprocating vertically. The second cylinder 52 is drivably connected to the manipulator 4. Using the manipulator 4 to grasp and place the outer tube into the outer tube receiving cavity further saves space and can be performed simultaneously with terminal feeding, thereby improving production efficiency.

[0046] As a further optimization of this embodiment, the outer tube feeding mechanism 3 further includes an outer tube vibrating feeding tray 31 , which is connected to the outer tube feeding channel 3 and is used to supply outer tubes to the outer tube feeding channel 3 .

[0047] A third terminal vibrating feed tray 6 is further provided on one side of the temporary storage portion 7. A third terminal feeding channel 61 is provided at the end of the third terminal vibrating feed tray 6. The third terminal feeding channel 61 has a downwardly curved arc surface at the end. The third terminal feeding channel 61 is provided above the temporary storage portion 7 and is used to drive the third terminal to fall into the temporary storage portion 7. Gravity is used to cause the third terminal to fall into the temporary storage portion 7, thereby reducing the number of power output components and achieving greater energy conservation and environmental protection.

[0048] As a further optimization of this embodiment, the clamping mechanism 1 includes a movable clamping portion 11 and a first drive assembly 12. The first drive assembly 12 drives and connects the clamping portion 11 to drive the clamping portion 11 to move between a first position and a second position. When the clamping portion 11 is in the first position, the terminal feeding mechanism 2 and the outer tube feeding mechanism 3 feed the clamping portion 11. In this embodiment, the first drive assembly 12 includes a rotating arm 13 and a power assembly that drives the rotating arm 13 to rotate. The clamping portion 11 is detachably connected to the rotating arm 13. In this way, modular assembly of the clamping portion 11 is achieved. Production personnel can select different clamping portions 11 according to the heat shrink tubes that need to be processed, thereby achieving rapid replacement of processing categories and improving the processing application scenarios of the equipment.

[0049] The power assembly is connected to the middle portion of the rotating arm 13, and the two clamping portions 11 are provided, one at each end of the rotating arm 13. This allows for rapid switching of the clamping portion 11 between the first and second positions. Preferably, the power assembly utilizes a rotary cylinder, which offers fast response and high safety performance. As a further optimization of this embodiment, the power assembly is connected to the middle portion of the rotating arm 13, and the number of clamping portions 11 can be increased or decreased as needed by simply increasing or decreasing the number of rotating arms 13 accordingly.

[0050] The terminal feeding mechanism 2 includes: a feeding channel 21, a cutting assembly 23 and an alignment assembly. The feeding channel 21 is used to convey the terminal blank, specifically, the terminal blank is a long tube. Feeding wheel assemblies 22 are provided on both sides of the feeding channel 21 to drive the terminal blank forward or backward, and the feeding wheels rotate in opposite directions to drive the terminal blank to be conveyed or retreated. The cutting assembly 23 is arranged above the feeding channel 21 and is used to cut the terminal blank. Specifically, the cutting assembly 23 includes a blade that can move downward, and the blade drive is connected to a cylinder 231, and the terminal blank is cut by the movement of the blade. The alignment assembly is arranged at the end of the feeding channel and can be pushed toward the clamping part 11 to assist the first terminal / second terminal to enter the first terminal accommodating cavity 1111 / second terminal accommodating cavity 1112. Specifically, the alignment assembly includes a copper tube 24 connected to the feed channel 21. The copper tube 24 is provided with a slit corresponding to the blade arrangement and configured to accommodate the blade's passage. The copper tube 24 is driven by a cylinder 25 to reciprocate along the axis of the copper tube 24. In operation, the feed wheel assembly 22 drives the terminal blank to be fed. When the predetermined terminal length is reached, the blade in the cutting assembly 23 moves through the slit in the copper tube 24, thereby cutting the terminal blank and returning to its initial position. The feed wheel assembly 22 continues to feed the terminal blank. The copper tube 24 is pushed toward the clamping portion 11 and aligned with the first terminal accommodating cavity 1111 or the second terminal accommodating cavity 1112 on the outer clamping portion 111. The feed wheel pushes the terminal into the first terminal accommodating cavity 1111 or the second terminal accommodating cavity 1112, completing the terminal feeding operation. The cylinder 25 then drives the copper tube 24 back to its initial position. Simultaneously, the feed wheel assembly 22 reverses, driving the terminal blank back to a position a predetermined terminal length away from the initial position, thus entering the next cycle.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
