Description

Technical Field

[0002] A terminal crimping machine is a combination of equipment used to crimp wires and insert plastic casings. It involves multiple processes, including wire feeding, cutting, stripping, tinning, crimping, and inserting the plastic casing. Before crimping, the rubber coating on the wire ends must be cut and stripped to expose the fiber core.

[0003] There are many types of wires. Some wires have dozens or even hundreds of thin wire cores. The cores of these wires are very fragile. In the traditional wire cutting rubber process, due to the slight difference in rubber thickness in different directions, the end of the wire will bend when cut by the cutter. Figure 7 As shown, in such cases, the cutter is likely to cut the wire core, thereby causing the quality of the wire to be damaged. In view of this, the inventor has made a new invention.

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1 to 7 The present invention will be described in detail.

[0033] The present invention provides a terminal stripping device, comprising a mounting plate 1, on which a movable clamping mechanism 2, a positioning clamping mechanism 3 and a rubber cutting mechanism 4 are sequentially provided. Specifically:

[0034] The movable clamping mechanism 2 is provided with a first clamper 21 and a first driving device 22 for driving the first clamper 21 to move, which is used to clamp and move the wire; the positioning clamping mechanism 3 is provided with a second clamper 31 and a second driving device 32 for driving the second clamper 31 to move, which is used to fix the end of the wire; the rubber cutting mechanism 4 is provided with a first cutter 41 and a second cutter 42, and a third driving device 43 for driving the first cutter 41 and the second cutter 42 to move, the first cutter 41 and the second cutter 42 are located between the first clamper 21 and the second clamper 31, and are used to cut the wire rubber. In the solution of the present invention, other equipment of the terminal crimping machine transports the wire to the stripping device, the first clamper 21 clamps the wire, and then the first drive device 22 drives the first clamper 21 to move toward the second clamper 31. When the first clamper 21 moves to a specified position, the second drive device 32 drives the second clamper 31 to clamp and fix the end of the wire to position the wire. The wire is straight under the cooperation of the first clamper 21 and the second clamper 31, and then the third drive device 43 drives the first cutter 41 and the second cutter 42 to cooperate to cut the rubber of the wire. After the rubber of the wire is cut to a certain depth, the first cutter 41 and the second cutter 42 are reset. Finally, the first clamper 21 clamps the wire and moves away from the second clamper 31. The second clamper 31 clamps the cut rubber to separate the rubber from the wire core, completing the wire stripping operation, greatly reducing the probability of damage after wire stripping and improving production capacity.

[0035] The first clamper 21 is provided with a cylinder 2103, the cylinder 2103 is provided with a telescopic rod 2104, a fixed shell 2105 is provided below the cylinder 2103, and a symmetrical first curved arm 2106 and second curved arm 2107 are provided in the fixed shell 2105. The ends of the first curved arm 2106 and the second curved arm 2107 are respectively provided with a first clamping jaw 2108 and a second clamping jaw 2109. The telescopic rod 2104 can drive the first curved arm 2106 and the second curved arm 2107 to clamp the wire. When the cylinder 2103 drives the telescopic rod 2104 to extend, the telescopic rod 2104 drives the first curved arm 2106 and the second curved arm 2107 to swing, so that the first clamping jaw 2108 and the second clamping jaw 2109 move away from each other, and the first clamper 21 is in an open state; conversely, when the cylinder 2103 drives the telescopic rod 2104 to retract, the telescopic rod 2104 drives the first curved arm 2106 and the second curved arm 2107 to swing, and the first clamping jaw 2108 and the second clamping jaw 2109 close together to cooperate in grabbing the wire, and the wire grabbing speed is fast.

[0036] The second drive device 32 is provided with a rotating rod b33. The upper and lower halves of the rotating rod b33 are respectively provided with a first threaded portion 34 and a second threaded portion 35 with opposite thread directions. The second clamp 31 is provided with a threaded sleeve b3101 threadedly connected to the first threaded portion 34 and a threaded sleeve c3102 threadedly connected to the second threaded portion 35. The threaded sleeve b3101 and the threaded sleeve c3102 are respectively provided with a third clamping jaw 3103 and a fourth clamping jaw 3104. The first threaded portion 34 and the second threaded portion 35 have opposite thread directions and the same pitch. When the rotating rod b33 rotates, the threaded sleeve b3101 and the threaded sleeve c3102 move closer to or away from each other, causing the third clamping jaw 3103 and the fourth clamping jaw 3104 to move closer together to clamp and secure the wire.

[0037] The third clamping jaw 3103 and the fourth clamping jaw 3104 are both provided with an arc-shaped groove portion 3105. Figure 5 As shown, the third jaw 3103 and the fourth jaw 3104 are V-shaped and can be crossed and closed. The arc-shaped groove portion 3105 is arranged in the middle of the inner angle of the third jaw 3103 and the fourth jaw 3104. After the third jaw 3103 and the fourth jaw 3104 clamp the wire, they can prevent the wire from bending.

[0038] The third drive device 43 is equipped with a rotating rod c44. The upper and lower halves of the rotating rod c44 are respectively provided with a third threaded portion 45 and a fourth threaded portion 46 with opposite thread directions. The first cutter 41 is provided with a threaded sleeve d411 threadedly connected to the third threaded portion 45, and the second cutter 42 is provided with a threaded sleeve e421 threadedly connected to the fourth threaded portion 46. The third and fourth threaded portions 45, 46 not only have opposite thread directions but also have the same pitch. When the rotating rod c44 rotates, the threaded sleeve d411 and the threaded sleeve e421 move closer or further away from each other, allowing the first cutter 41 and the second cutter 42 to cooperate in cutting the rubber of the wire rod. The stripping device of the present invention has a compact structure, a short operating stroke, and a fast stripping speed and high efficiency.

[0039] The mounting plate 1 is provided with a second guide rail 14 movably connected to the positioning and clamping mechanism 3, and a third guide rail 15 movably connected to the rubber cutting mechanism 4. More specifically, the threaded sleeves b3101 and c3102 are each provided with a second guide block 3106 movably connected to the second guide rail 14, and the threaded sleeves d411 and e421 are each provided with a third guide block 423 movably connected to the third guide rail 15. This allows the threaded sleeves b3101, c3102, d411, and e421 to move smoothly, resulting in high structural stability.

[0040] The mounting plate 1 is provided with a first guide block 13. The first clamp 21 is provided with a first guide rail 2101 movably connected to the first guide block 13. The first guide rail 2101 is provided with a threaded sleeve a2102. The first drive device 22 is provided with a rotating rod a23 threadedly connected to the threaded sleeve a2102. The first drive device 22 is a motor. The connection between the rotating rod a23 and the threaded sleeve a2102 converts the rotational kinetic energy of the first drive device 22 into linear kinetic energy, thereby causing the first clamp 21 to move linearly. This provides high transmission force, low movement inertia, and high precision.

[0041] The present invention also provides a fixed wire stripping method, including the above-mentioned terminal crimping machine stripping device, the first clamper 21, the second clamper 31 and the first cutter 41, the second cutter 42 cooperate to strip the wire, the steps are as follows:

[0042] S1: The wire reaches the designated position, and the first clamp 21 clamps the wire. The first clamp 21 then shifts, causing the end of the wire to move toward the second clamp 31. This step is the wire feeding process. The first clamp 21 holds the wire at a distance from the end of the wire. This distance is greater than the length of the rubber to be stripped, facilitating the second clamp 31 to hold the wire and the first and second cutters 41 and 42 to cut the rubber.

[0043] S2: The second clamp 31 clamps the end of the wire to fix the wire. This step is for wire alignment. The position of the second clamp 31 corresponds to the position of the first clamp 21 to prevent the wire from bending.

[0044] S3: The first and second cutters 41 and 42 cooperate to cut the rubber coating of the wire. This step is to straighten the coating. The second holder 31 has an arc-shaped groove 3105 that can position the wire, keeping the wire straight. This allows the first and second cutters 41 and 42 to accurately cut the rubber coating and prevent the first and second cutters 41 and 42 from cutting the wire core.

[0045] S4: First cutter 41 and second cutter 42 are reset, and first clamp 21 moves to extract the wire from second clamp 31. Second clamp 31 grips the cut rubber, separating it from the wire core, completing the wire stripping process. This step involves pulling the rubber apart. Cutting the rubber with the cutter and then pulling and stripping it with first clamp 21 and second clamp 31 significantly reduces the risk of wire damage after stripping, significantly increasing production capacity.

[0046] In step S2 , after the second clamper 31 clamps the wire, the first clamper 21 moves a short distance, and the first clamper 21 and the second clamper 31 cooperate to straighten the wire to prevent the first cutter 41 and the second cutter 42 from cutting the wire core.

[0047] In steps S3 and S4, the first and second cutters 41 and 42 cut the rubber to a depth of 90% to 95% of the rubber's thickness. The first clamp 21 then moves the wire, and the first and second clamps 21 and 31 cooperate to sever the rubber. After the first and second cutters 41 and 42 cut the rubber, the first and second clamps 21 and 31 easily sever the rubber without twisting the wire, creating a smooth, even cut. The wire stripping process involves feeding, positioning, straightening, cutting, and pulling the wire, resulting in high-quality stripping.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
