Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and specifically relates to an improved terminal stripping machine. Background Technology

[0002] Terminals are commonly used components in electrical connections. In electrical engineering, terminals often refer to wiring terminals, also called wire terminals. They can be categorized by type (single-hole, double-hole, socket, hook, etc.) and by material (copper-plated silver, copper-plated zinc, copper, aluminum, iron, etc.). Their primary function is to transmit electrical signals or conduct electricity. Terminals are essential for connecting signal lines to other devices; otherwise, the signal line cannot be connected or establish communication. Terminal crimping machines use a crimping head to fix the terminal to be installed and the signal line, then apply pressure to the terminal to be installed, thus tightly fitting the terminal onto the end of the signal line. Terminal stripping machines include steps such as wire fixing, stripping, twisting, terminal crimping, and wire release. The entire device is relatively large and inconvenient to move and disassemble.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0028] like Figure 1-8As shown, the terminal stripping and crimping machine 100 in one embodiment of this utility model includes a housing 10, a rotating base 20, a wire stripping and twisting mechanism 30, a terminal crimping mechanism 40, a terminal storage mechanism 50, and a terminal handling mechanism 60. The housing 10 has a wire insertion hole 11. The wire stripping and twisting mechanism 30 is installed in the housing 10, facing the wire insertion hole 11, and is used to strip the insulation layer of the wire and twist the dispersed wire bundle into a single strand. The rotating base 20 is installed inside the housing 10, and is connected to and drives the terminal crimping mechanism 40 to approach or move away from the wire insertion hole 11. The terminal crimping mechanism 40 is used to crimp the terminal onto the wire, and includes a main mold 41, a drive mold 42, a fourth cylinder 43, two crimping blocks 44, and two connecting rods 45. The main mold 41 includes two parallel first plates connected on one side, each first plate having a rectangular through groove 411, and the two through grooves 411 are coaxial. The drive mold 42 is provided with two inclined first grooves 421, and two pressing blocks 44 are disposed in the through grooves 411. A connecting rod 45 is positioned between two first plates and pivotally connected to them; its first end is pivotally connected to the pressing block 44, and its second end is connected to the first grooves 421. A fourth cylinder 43 is connected to and drives the drive mold 42 to move closer to or away from the main mold 41. A terminal storage mechanism 50 is disposed within the housing 10 for storing terminals. A terminal conveying mechanism 60 is installed within the housing 10 for conveying terminals from the terminal storage mechanism 50 to the terminal pressing mechanism 40.

[0029] During operation, the wire stripping and twisting mechanism 30 first faces the wire socket 11, and the terminal transport mechanism 60 transfers the terminal from the terminal storage mechanism 50 to the terminal crimping mechanism 40. The wire is inserted into the wire socket 11, and the wire stripping and twisting mechanism 30 strips the wire insulation and twists the dispersed wire bundle into a single strand. Then, the rotating base 20 rotates, moving the terminal crimping mechanism 40, which carries the terminal, to a position facing the wire socket 11, where it completes the crimping action of fixing the terminal to the wire. Afterwards, the crimped wire is removed, and the rotating base 20 moves the terminal crimping mechanism 40 away from the wire socket 11, waiting for the terminal transport mechanism 60 to deliver another terminal. The wire stripping and twisting mechanism 30 then faces the wire socket 11 and waits for the wire to be inserted.

[0030] The terminal stripping machine 100 in this embodiment adopts an improved terminal crimping mechanism 40, which has a simple structure, small size, and low cost, and can simplify the overall internal structure and reduce the overall volume.

[0031] Specifically, in the terminal crimping mechanism 40, two crimping blocks 44 are used to fix and crimp the terminal onto the wire. The terminal crimping mechanism 40 employs a lever principle. During operation, the fourth cylinder 43 drives the drive mold 42 to move towards the main mold 41, and the first end of the connecting rod 45 moves outward along the first slide groove 421. Therefore, its second end drives the crimping blocks 44 to move closer together, thus crimping the terminal onto the wire. After the crimping action is completed, the fourth cylinder 43 drives the drive mold 42 away from the main mold 41, and the first end of the connecting rod 45 moves inward along the first slide groove 421, while the second end drives the crimping blocks 44 to move away from each other to release the terminal.

[0032] The terminal storage mechanism 50 discharges material by vibration. It includes a storage tank 51 and multiple vibration cylinders 52 fixed to the bottom of the housing 10. The storage tank 51 is supported on the vibration cylinders 52 and is driven by the latter to reciprocate in the vertical direction.

[0033] The terminal storage mechanism 50 also includes a base plate 54 fixed to the output shaft of the vibrating cylinder 52, and a plurality of push rods 55 fixed to the base plate 54 and facing the vibrating cylinder 52. The storage bin 51 is fixed to the base plate 54. The number of push rods 55 is the same as the number of vibrating cylinders 54, and each push rod 55 is positioned above its corresponding vibrating cylinder 54. When the vibrating cylinder 52 drives the base plate 54 downward, the push rods 55 can collide with the vibrating cylinder 52, causing the terminals in the storage bin 51 to bounce and jolt under the action of inertia, thereby improving the discharge of materials.

[0034] Preferably, the fixed position of the top rod 55 on the base plate 54 is adjustable, that is, the distance of its protrusion from the bottom surface of the base plate 54 is adjustable. Therefore, the vibration range of the storage tank 51 is adjustable, which can better adapt to terminals of different specifications.

[0035] Furthermore, rubber pads or other flexible shock-absorbing blocks can be installed at the bottom of the push rod 55 to reduce the noise generated when the push rod 55 collides with the vibrating cylinder 52.

[0036] The terminal storage mechanism 50 also includes an annular discharge track 53, one end of which is connected to the storage tank 51 and surrounds the periphery of the storage tank 51. The other end of the discharge track 53 is the discharge port of the entire terminal storage mechanism 50. When the storage tank 51 is vibrated by the vibration cylinder 52, the terminals flow out of the storage tank 51 and into the discharge track 53. While in the discharge track 53, the terminals move towards the discharge port due to the vibration.

[0037] Preferably, the discharge track 53 is divided into two sections in the vertical direction. The upper section is wider, allowing the terminal sleeve portion to enter, while the lower section is narrower, allowing only the terminal block portion to enter. Therefore, the terminals can enter the discharge track 53 in a uniform posture (sleeve facing upwards), facilitating the terminal handling mechanism 60 to handle the terminals.

[0038] The terminal handling mechanism 60 includes a positioning disk 61 and a material picking component 62. The positioning disk 61 is located at the discharge port of the discharge track 53. The positioning disk 61 has multiple positioning holes 611 with different diameters and multiple inlets 612 that connect to the different positioning holes 611. After the terminal leaves the discharge track 53, it enters the positioning hole 611 through the inlet 612 and is then transferred to the terminal crimping mechanism 40 by the material picking component 62.

[0039] The material handling assembly 62 includes a first cylinder 621, a second cylinder 622, a third cylinder 623, and two grippers 624. The first cylinder 621 is connected to and drives the grippers 623 to move closer to or further away from each other. The second cylinder 622 is connected to and drives the first cylinder 621 to move closer to or further away from the positioning disk 61 or the terminal crimping mechanism 40 in the vertical direction. The third cylinder 623 is connected to and drives the second cylinder 622 to move closer to or further away from the positioning disk 61 or the terminal crimping mechanism 40 in the horizontal direction.

[0040] Preferably, a fifth cylinder 34 is installed at the bottom inside the housing 10, and the wire stripping and twisting mechanism 30 is supported on the fifth cylinder 34. The fifth cylinder 34 extends along the axial direction of the wire insertion hole 11 and is used to drive the wire stripping and twisting mechanism 30 to move to a position close to the wire insertion hole 11 when it is necessary to perform wire stripping and twisting action, and to drive the wire stripping and twisting mechanism 30 to move back and away from the wire insertion hole 11 when it is necessary to perform terminal crimping action, so as to prevent the rotating base 20 from interfering with the wire stripping and twisting mechanism 30 when rotating it.

[0041] The rotating base 20 includes a mounting plate 21, a first motor 22, a support base 23, and a rotating shaft 24. The support base 23 is fixed inside the housing 10, and the rotating shaft 24 is rotatably disposed inside the support base 23. The mounting plate 21 is fixed to one end of the rotating shaft 24, and the first motor 22 is fixed on the support base 23 and connected to the other end of the rotating shaft 24. By driving the rotating shaft 24 to rotate, the stripping and twisting mechanism 30 is rotated to a position facing the guide hole 11 or above the stripping and twisting mechanism 30.

[0042] Preferably, a first gear 25 is mounted on the output shaft of the first motor 22, and a second gear 26 is mounted on the rotating shaft 24. The two gears are connected by a belt. The diameter of the first gear 25 is smaller than the diameter of the second gear 26. This gear ratio design (similar to a speed reducer) can reduce the rotational speed of the rotating shaft 24 and the wire stripping and twisting mechanism 30, avoiding excessive rotation.

[0043] The wire stripping and twisting mechanism 30 includes a support 31, a drive assembly, and a working assembly. The drive assembly includes a sixth cylinder 321, a second motor 322, a first gear 323, and a second gear 324. The sixth cylinder 321 and the second motor 322 are respectively fixed to the support 31. The first gear 323 is fixed to the output shaft of the second motor 322, and the second gear 324 is rotatably mounted on the support 31. The working assembly is connected to the second gear 324 and can rotate with it. It includes two blades 331 and two clamping blocks 332. The sixth cylinder 321 connects to and drives the two blades 331 and the two clamping blocks 332 to move closer or further apart.

[0044] After insertion through the wire socket 11, the wire is inserted between the two guide plates 331 and the two clamping blocks 332. The sixth cylinder 321 drives the two blades 331 and the clamping blocks 332 to move closer to each other and contact the wire. Then, the second motor 322 drives the first gear 323 and the second gear 324 to rotate, which in turn drives the blades 331 and the clamping blocks 332 to rotate synchronously. The blades 331 cut the insulation layer of the wire, and the clamping blocks 332 hold the cut insulation layer and twist any resulting wire bundle into a single wire during subsequent rotation. Then, the second motor 322 stops, the sixth cylinder 321 reverses, and drives the blades 331 and the clamping blocks 332 to move away from each other, thereby releasing the wire.

[0045] Preferably, the terminal stripper 100 further includes a wire clamping mechanism 70, which is disposed within the housing 10 and located between the wire stripping and twisting mechanism 30 / terminal crimping mechanism 40 and the wire insertion hole 11, for clamping and fixing the wire. The wire clamping mechanism 70 includes a wire clamping base 71, a wire clamping cylinder 72, and two toothed molds 73. The wire clamping base 71 is fixed to the inner bottom plate of the housing 10, and the wire clamping cylinder 72 is fixed to the wire clamping base 71. It connects to and drives the two toothed molds 73 to move closer to each other to clamp the wire, or to move further apart to release the wire. Each toothed mold 73 includes two rows of teeth arranged in an alternating manner at a certain angle to improve the wire clamping effect.
