DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the present invention is an automatic wire stripping device, comprising a straightening mechanism 1, an inlet pinch roller mechanism 2, a bypass mechanism 3, a cutting and stripping mechanism 4, an outlet pinch roller mechanism 5, an operating panel 6, an intermediate conductor holder 7, and a scrap box 8. The straightening mechanism 1 is disposed at the front end of the inlet pinch roller mechanism 2, and the bypass mechanism 3, the cutting and stripping mechanism 4, the intermediate conductor holder 7, and the outlet pinch roller mechanism 5 are sequentially disposed at the rear end of the inlet pinch roller mechanism 2; the scrap box 8 is disposed below the outlet pinch roller mechanism 5, and the operating panel 6 is disposed on the device body for controlling device operation and setting operating parameters, such as the cut length, wire diameter, stripping length, or cutting length of the wire to be stripped.

[0022] like Figure 2As shown, the straightening mechanism 1 includes an inlet conductor holder 11, straightening rollers 12, a mounting plate 13, an outlet conductor holder 14, and a first conductor tube 15. The inlet conductor holder 11, straightening rollers 12, and outlet conductor holder 14 are all mounted on the mounting plate 13. In this embodiment, five straightening rollers 12 are provided, and the five straightening rollers 12 are staggered. The first conductor tube 15 is positioned adjacent to the outlet conductor holder 14. The conductor passes through the inlet conductor holder 11 and into the straightening rollers 12. After passing through the straightening rollers 12, the conductor enters the outlet conductor holder 14 through the first conductor tube 15 and enters the inlet pinch roller mechanism 2. The straightening mechanism 1 bends and deforms the conductor before it enters the inlet pinch roller mechanism 2, thereby straightening it. This facilitates smooth movement of the conductor at all stages of the stripping process.

[0023] like Figure 3 and Figure 4 As shown, the inlet pinch roller mechanism 2 includes an electric push rod 21 , a pinch upper roller 22 , an upper roller swing arm 23 , a pinch lower roller 24 , a transmission gear 25 , a rear mounting plate 26 , a reducer 27 and a drive motor 28 . Several transmission gears 25 are mounted on the rear mounting plate 26. Two meshing gears drive the upper pinch roller 22 and the lower pinch roller 24, respectively. The upper pinch roller 22 is mounted on an upper roller swing arm 23, which is hinged to the rear mounting plate 26 at the axis of the transmission gear 25 that drives the upper pinch roller 22. An electric push rod 21 drives one end of the upper roller swing arm 23, controlling the downward pressure and expansion of the upper pinch roller 22, and thereby the opening between the upper pinch roller 22 and the lower pinch roller 24, to accommodate different wire diameters. A motor 28 drives a reducer 27 to rotate the transmission gear 25, which in turn drives the upper pinch roller 22 and the lower pinch roller 24 to rotate, enabling the wire to be fed in. The electric push rod 21 has a built-in position detection unit that automatically controls the downward pressure of the upper pinch roller 22 according to the wire diameter value set by the program. The driving motor 28 can automatically calculate the number of rotations according to the length dimension set by the program to achieve cutting to the set length dimension.

[0024] like Figure 5 As shown, the avoidance mechanism 3 includes an electromagnet 31, a swinging piece 32, a rotating shaft 33, and a second wire tube 34. The electromagnet 31 is located above and below one end of the swinging piece 32. Power is applied to the electromagnet 31 to drive the swinging piece 32 up and down. The other end of the swinging piece 32 and the second wire tube 34 are connected by the rotating shaft 33 to achieve the up and down swing of the conduit. The avoidance mechanism 3 is used to leave space for the wire to retreat during tail-end stripping, thus achieving tail-end stripping.

[0025] like Figure 6 and Figure 7As shown, the cutting and stripping mechanism 4 includes a cutting blade 41, a connecting seat 42, a bearing seat 43, a lead screw nut 44, a guide rail 45, a forward and reverse lead screw 46, a bevel gear 47, an encoder 48, a motor seat 49, and a reduction motor 410. The reduction motor 410 drives the forward and reverse lead screw 46 to rotate via the bevel gear 47, thereby driving the lead screw nut 44 on the forward and reverse lead screw 46 to move up and down. The two ends of the forward and reverse lead screw 46 are mounted on the bearing seat 43, and a guide rail 45 is provided between the two bearing seats 43. The connecting seat 42 is mounted on the lead screw nut 44 and can move along the guide rail 45. The cutting blade 41 is mounted on the connecting seat 42. When the lead screw nut 44 moves up and down, it is driven by the connecting seat 42 to open and close the cutting blade 41, thereby achieving wire cutting and stripping. The encoder 48 is mounted on the motor seat 49. The encoder 48 cooperates with the bevel gear on the forward and reverse lead screw 46 through the bevel gear 47 to provide real-time feedback on the position of the lead screw nut 44, thereby controlling the opening size of the cutting blade 41.

[0026] like Figure 8 As shown, the structure of the outlet pinch roller mechanism 5 of the present invention is the same as that of the inlet pinch roller mechanism 2, so it will not be described in detail.

[0027] The working process of this utility model is:

[0028] Step 1: Parameter setting: The operator inputs the cutting length, wire diameter, stripping length and cutting length of the wire to be stripped through the operation panel;

[0029] Step 2: Threading the wire: Manually thread the wire into the entrance pinch roller mechanism for the first time;

[0030] Step 3, trimming zero: The inlet and outlet pinch roller mechanism is automatically pressed down to the set position according to the wire diameter input on the operation panel. The pinch roller rotates forward to drive the wire forward to the trimming length. Then the shear blade closes to cut the wire. The cut front part is discarded. The length calculated by the inlet pinch roller mechanism is reset to zero and the fixed length calculation begins.

[0031] Step 4: Head end stripping: The inlet and outlet pinch rollers rotate forward at a constant speed to drive the wire forward to the stripping length and then stop. The shear blades then close to the wire diameter width, cutting off the outer sheath of the wire while keeping the inner copper wire intact. The outlet pinch rollers then rotate to deliver the cut wire sheath out.

[0032] Step 5: Cut to length: After the head end is stripped, the shear blade opens, the inlet and outlet pinch rollers rotate forward to drive the wire to the cutting length, and then the shear blade closes to cut the wire;

[0033] Step 6: Tail end avoidance: After the shear blade closes and cuts the wire, the electromagnet of the avoidance mechanism is attracted, driving the second wire tube of the avoidance mechanism to swing upward, making space for the next step of tail end stripping;

[0034] Step 7, tail end stripping: After the tail end avoidance action is completed, the outlet pinch roller reverses to drive the wire back to the stripping length, and the shear blade closes to the wire diameter width, cutting the outer sheath of the wire while keeping the inner copper wire connected. Then the outlet pinch roller rotates forward to send out the wire after the tail end stripping; the shear blade opens, and the second wire tube of the avoidance mechanism swings down to the horizontal position, waiting for the stripping of the next wire.

[0035] The above steps 3-7 are all performed automatically after the parameters are set, without manual intervention. When changing wire diameters of different specifications, steps 1-7 will be performed on the first wire. When stripping continuously without changing specifications, steps 1-3 are not performed on subsequent wires except the first wire.

[0036] The above content is a further detailed description of the present invention in combination with specific preferred implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or replacements without departing from the concept of the present invention, which should be regarded as falling within the scope of protection of the present invention.
