Description

Technical Field

[0001] This utility model relates to the field of terminal crimping machine technology, and more specifically to an aviation terminal crimping machine. Background Technology

[0002] A terminal crimping machine is a device that presses terminals onto the front end of a wire. A typical terminal crimping machine has several functions, including wire feeding, stripping, terminal insertion, terminal crimping, and defect detection. It is fully automated and has high production efficiency.

[0003] However, in existing terminal crimping machines, the wire tip is stripped and then directly enters the terminal insertion step. Since the terminal hole diameter is small and the wire is composed of multiple strands of metal wire, if the metal wire is thin, during the insertion process between the wire tip and the terminal, a small portion of the metal wire may not be inserted into the terminal due to insufficient wire cohesion, resulting in a high defect rate or risks after leaving the factory.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] An aviation terminal crimping machine includes: a frame 100, a stripping and twisting mechanism 200 mounted on the frame 100, and a terminal crimping mechanism 300.

[0023] like Figure 1 As shown, the frame 100 is a cabinet-type structure that serves as a support. When the cabinet door is closed, it also serves as a protective measure to prevent accidental injury to users during equipment operation. It also provides some degree of dust and water protection.

[0024] like Figure 3-6 As shown, the peeling and twisting mechanism 200 includes: a peeling knife assembly 210 and a twisting assembly 220; The stripping blade assembly 210 mainly functions to cut the insulation at the front end of the wire. The stripping blade assembly 210 includes: a first blade 211 and a second blade 212 symmetrically distributed, at least one of the first blade 211 and the second blade 212 being connected to a first driving member 213 and driven to move to perform the cutting action; like Figure 3 and Figure 4 As shown, the first blade 211 and the second blade 212 are positioned vertically opposite each other, with the first blade 211 on top and the second blade 212 on the bottom. In one structural configuration, the second blade 212 can be fixedly installed, and the first blade 211 is connected to the first driving member 213. The first driving member 213 drives the first blade 211 to move downward and cooperate with the second blade 212 to cut the insulation at the front end of the wire 00. In a second structural configuration, the first blade 211 can be fixedly installed, and the second blade 212 is connected to the first driving member 213. The first driving member 213 drives the second blade 212 to move upward and cooperate with the first blade 211 to cut the insulation at the front end of the wire 00. In a third structural configuration, both the first blade 211 and the second blade 212 are movable, and the first driving member 213 drives them to move towards each other, with the first blade 211 and the second blade 212 cooperating to cut the wire 00.

[0025] Continue as Figure 3 and Figure 4As shown, the first driving component 213 includes: a first motor 2131, a lead screw 2132 driven by the first motor 2131, and a lead screw nut 2133 assembled on the lead screw 2132; the first blade 211 and the second blade 212 are respectively mounted on the lead screw nut 2133 through the blade bracket 214. like Figure 4 As shown, the lead screw 2132 includes a first rod segment 21321 and a second rod segment 21322 connected to each other. The lower end of the first rod segment 21321 and the upper end of the second rod segment 21322 are fixedly connected. The threads on the first rod segment 21321 and the second rod segment 21322 are arranged in opposite directions. One lead screw nut 2133 is installed on the first rod segment 21321, and the first blade 211 is installed on the lead screw nut 2133 through the blade bracket 214. The other lead screw nut 2133 is installed on the second rod segment 21321. 322, the second blade 212 is mounted on the lead screw nut 2133 via the blade bracket 214; when the first motor 2131 rotates in the forward direction, it drives the first rod segment 21321 and the second rod segment 21322 to rotate in the forward direction at the same time, and the first blade 211 and the second blade 212 move towards each other to cut the insulation of the wire 00; when the first motor 2131 rotates in the reverse direction, it drives the first rod segment 21321 and the second rod segment 21322 to rotate in the reverse direction at the same time, and the first blade 211 and the second blade 212 move away from each other.

[0026] In addition, the first driving component 213 should also include a bracket, on which the first motor 2131 and the lead screw 2132 are mounted, and the bracket should be provided with a track groove. After the lead screw nut 2133 is installed on the lead screw 2132, it is restricted by the track groove to switch the rotational motion of the lead screw 2132 to the linear motion of the lead screw nut 2133 on the lead screw 2132.

[0027] Alternatively, in another embodiment, the first driving member 213 may include two driving cylinders, and the first blade 211 and the second blade 212 are driven to move up and down by a driving cylinder to achieve cutting.

[0028] like Figure 4 As shown, both the first blade 211 and the second blade 212 are provided with V-shaped cutting edges to cut wire 00.

[0029] like Figure 3 , Figure 5 and Figure 6 As shown, the twisting assembly 220 includes: a hollow rotating shaft 221, a rotating head 222 fixed to the first end of the rotating shaft 221, a first clamp 223 and a second clamp 224 symmetrically distributed within the rotating head 222, a second driving member 225 that drives the rotating shaft 221 to rotate, and a third driving member 226 that drives the first clamp 223 and the second clamp 224 to move.

[0030] like Figure 5 As shown, the rotating head 222 is located behind the first blade 211 and the second blade 212, that is... Figure 5 The rotating head 222 shown is located to the left of the first blade 211 and the second blade 212, and the wire is inserted from right to left.

[0031] The third driving component 226 includes: a collar 2261 sleeved outside the rotating shaft 221, a third cylinder 2262 that drives the collar 2261 to move along the axial direction of the rotating shaft 221, and a connecting arm 2263. The rotating head 222 includes: a first rotating block and a second rotating block assembled together, the second rotating block having a moving groove 2221, and a first chuck 223 and a second chuck 224 located between the first rotating block and the second rotating block; The moving groove 2221 is perpendicular to the insertion direction of the wire 00. Specifically, the moving groove 2221 can be horizontally set. The first clamp 223 and the second clamp 224 are respectively provided with inclined grooves 2231 and 2241. In the inclined grooves 2231 and 2241 of the first clamp 223 and the second clamp 224, "inclined" means that it is inclined relative to the axis of the rotation shaft 221, and the inclined grooves 2231 and 2241 of the first clamp 223 and the second clamp 224 point to the axis of the rotation shaft 221. The first chuck 223 and the second chuck 224 are at least partially located in the moving groove 2221. The first chuck 223 and the second chuck 224 may be provided with a locking block that engages with the moving groove 2221, which is used to guide the movement trajectory of the first chuck 223 and the second chuck 224. Alternatively, the first chuck 223 and the second chuck 224 may be entirely located in the moving groove 2221, which is also used to guide the movement trajectory of the first chuck 223 and the second chuck 224.

[0032] The first end of the connecting arm 2263 is connected to the inclined grooves 2231 and 2241 by a pin. There are two connecting arms 2263, one of which is connected to the inclined groove 2231 of the first chuck 223, and the other is connected to the inclined groove 2241 of the second chuck 224.

[0033] The second end of the connecting arm 2263 is provided with a groove, and the circumference of the collar 2261 is inserted into the groove. The second end of the connecting arm 2263 and the collar 2261 abut against each other in the axial direction of the rotating shaft 221, but do not abut against each other in the rotation direction of the rotating shaft 221. This allows the third cylinder 2262 to drive the collar 2261 to move along the axial direction of the rotating shaft 221, thereby driving the connecting arm 2263 to move linearly. When the second driving member 225 drives the rotating shaft 221 and the rotating head 222 to rotate, the second end of the connecting arm 2263 moves along the circumference of the collar 2261.

[0034] Furthermore, the pin at the first end of the connecting arm 2263 moves in the inclined grooves 2231 and 2241, driving the first chuck 223 and the second chuck 224 to move along the moving groove 2221 to open or close; Specifically, the third cylinder 2262 drives the collar 2261 to move towards the first end of the rotating shaft 221, and the first clamp 223 and the second clamp 224 move towards each other to close; the third cylinder 2262 drives the collar 2261 to move towards the second end of the rotating shaft 221, and the first clamp 223 and the second clamp 224 move in opposite directions to open.

[0035] like Figure 6 As shown, a feeding channel 201 is provided in the center of the rotating head 222. The feeding channel 201 is connected to the hollow part of the rotating shaft 221. The rotating head 222 is provided with a flared mouth near the surface of the first blade 211 and the second blade 212 to facilitate guiding the wire 00 into the feeding channel.

[0036] like Figure 5 As shown, with the first blade 211 and the second blade 212 in the open position, the wire 00 can move from right to left between the first blade 211 and the second blade 212. The third cylinder 2262 drives the collar 2261 towards the first end of the rotating shaft 221. Figure 5 The wire 00 moves from center to right. During the movement, the front end of the wire 00 enters the feeding channel 201 under the guidance of the horn mouth. At the same time, the first clamp 223 and the second clamp 224 move towards each other to close and clamp the front end of the wire 00. The first motor 2131 rotates in the forward direction, driving the first blade 211 and the second blade 212 to move towards each other to cut the insulation of the wire 00. After the cutting is completed, the first motor 2131 rotates in the reverse direction, driving the first blade 211 and the second blade 212 to move in opposite directions to reset. Then, the second driving component 225 drives the rotating shaft 221 to rotate, and the rotating head 222 follows the rotation. At this time, the wire 00 is fixed. When the first clamp 223 and the second clamp 224 clamp the front end of the wire and rotate, the metal wire in the wire 00 is twisted into a single strand, which is convenient for subsequent insertion into the terminal 01. Alternatively, the second driving member 225 can drive the rotating head 221 and rotating head 222 to rotate, and then the third cylinder 2262 can drive the collar 2261 to the second end of the rotating shaft 221. Figure 5 (From center to left) Move the first clamp 223 and the second clamp 224 in opposite directions to open, and at the same time pull out the insulation skin and detach it from the wire 00; at this time, the wire 00 can move synchronously to pull out the feeding channel 201.

[0037] Alternatively, the second driving element 225 can drive the rotating head 221 and rotating head 222 to rotate, while the third cylinder 2262 drives the collar 2261 towards the second end of the rotating shaft 221. Figure 5(From center to left) Move the first clamp 223 and the second clamp 224 in opposite directions to open them up, so that the insulation is pulled out first while rotating and twisting the wire.

[0038] Furthermore, such as Figure 3 and Figure 5 As shown, the second driving component 225 includes: a second motor 2251, a driving gear 2252 fixed to the output shaft of the second motor 2251, a driven gear 2253 fixedly mounted on the rotating shaft 221, and a belt 2254 wound around the driving gear 2252 and the driven gear 2253. The second motor 2251 rotates by linking the rotating shaft 221 with the driving gear 2252, the driven gear 2253 and the belt 2254.

[0039] In addition, the second drive component 225 and the third drive component 226 can be mounted on a bracket for support, and the rotating shaft 221 can also be mounted on the bracket for support. However, a bearing can be provided between the rotating shaft 221 and the bracket to facilitate the rotation of the rotating shaft 221.

[0040] Furthermore, the second end of the rotating shaft 221 is connected to a suction mechanism, which is not shown in the figure. It adopts existing technology and its main function is to suck out the cut insulation skin that has entered the feeding channel.

[0041] In one implementation, such as Figure 9-12 As shown, the crimping terminal mechanism 300 includes: a four-point crimping assembly 310 and a fourth driving member 320; The four-point crimping assembly 310 has a rotating plate 311, a limiting block 312, and multiple pressing blocks 313; The first end of the rotating plate 311 is provided with a through hole 3111. Multiple release positions 3112 are provided radially outward on the inner wall of the through hole 3111. The fourth motor 321 drives the rotating plate 311 to rotate around the center of the through hole 3111 via the drive plate 322. The limiting block 312 and multiple pressing blocks 313 are installed in the through hole 3111. The first end of the pressing block 313 points to the center of the through hole 3111. The first ends of the multiple pressing blocks 313 together form the crimping hole through which the terminal 01 passes. The second end of the pressing block 313 is supported on the inner wall of the through hole 3111. The second end of the pressing block 313 is connected to an elastic element (not shown in the figure). The elastic element provides the force for the pressing block 313 to move radially outward.

[0042] The fourth driving component 320 includes: a fourth motor 321, a driving plate 322, and a pressure sensor 323; the driving plate 322 is connected to the rotating plate 311; the up and down movement of the driving plate 322 drives the rotating plate to move forward and backward, so that the four-point pressing assembly presses the terminal or releases the terminal.

[0043] like Figure 12As shown, the through hole 3111 is configured with a variable diameter. Specifically, the through hole 3111 has four identical first arc-shaped segments located on the same circumference. Adjacent first arc-shaped segments are connected by an outwardly protruding second arc-shaped segment. The four second arc-shaped segments have the same curvature and length. The first and second arc-shaped segments are alternately arranged to achieve the variable diameter configuration of the through hole. The release position 3112 is formed on the rotating plate 311 corresponding to the second arc-shaped segment.

[0044] When the first end of the rotating plate 311 rotates to the second end of the pressure block 313 and enters the release position 3112, the pressing hole is in the open state. When the first end of the rotating plate 311 rotates until the second end of the pressure block 313 leaves the release position 3112, the pressing hole is in a tightened state.

[0045] Specifically, the fourth driving member 320 drives the rotating plate 311, causing the first end of the rotating plate 311 to rotate around the center of the through hole 3111. During the rotation, the second end of the pressure block 313 moves along the inner wall of the through hole 3111. When the second end of the pressure block 313 moves to the release position 3112, the pressure block 313 moves radially outward under the action of the elastic force of the elastic member, and the second end of the pressure block 313 presses against the second arc-shaped section. Multiple pressure blocks 313 move radially outward at the same time, and the crimping hole opens to facilitate the insertion of the terminal 01. The first end of the rotating plate 311 continues to rotate around the center of the through hole 3111. It rotates until the second end of the pressure block 313 leaves the release position 3112 and presses against the first arc segment. Under the change in diameter of the through hole 3111, the pressure block 313 moves radially inward, the crimping hole tightens, and the terminal 01 is flattened.

[0046] Furthermore, the elastic element can be a spring.

[0047] The limiting block 312 is used to limit the movement trajectory of the pressing block 313, and to prevent the pressing block 313 from rotating with the rotating plate 311 when it rotates. like Figure 10 As shown, the four-point crimping assembly 310 is installed on a support plate 330. A hole should be provided at the center of the support plate 330 and the limiting block 312. The terminal 01 passes through the hole and enters the crimping hole formed by multiple pressing blocks 313.

[0048] A vertical guide groove is provided at the support plate 330, and the drive plate 322 is installed in the guide groove to guide the drive plate 322 to move linearly up and down. The output shaft of the fourth motor 321 is connected to the eccentric wheel 3211. The fourth motor 321 is mounted on a gantry 324. The gantry 324 is provided with a sliding block 3241. The fourth motor 321 drives the eccentric wheel 3211 to rotate, which is converted into the sliding block 3241 moving up and down along the gantry 324. The sliding block 3241 is connected to a push rod 325. The lower end of the push rod 325 is connected to the drive plate 322. The pressure sensor 323 is mounted on the push rod 325.

[0049] During operation, the fourth motor 321 drives the eccentric wheel 3211 to rotate, which in turn causes the sliding block 3241 and the drive plate 322 to move up and down. The drive plate 322 drives the rotating plate 311 to rotate. When the drive plate 322 moves down, it drives the rotating plate 311 to move forward, causing the pressure block 313 to move inward to press the terminal. When the drive plate 322 moves up, it drives the rotating plate 311 to move in the opposite direction, causing the pressure block 313 to move outward to release the terminal.

[0050] The terminal crimping mechanism 300 also includes a pneumatic chuck 340 and a vibratory feeding assembly 350; the pneumatic chuck 340 is located in front of the four-point crimping assembly 310, and the pneumatic chuck 340 has a left chuck 341 and a right chuck 342. When the left chuck 341 and the right chuck 342 are clamped, a wire hole is formed, and the wire hole corresponds to the crimping hole. like Figure 2 and Figure 10 As shown, the vibratory feeding assembly 350 includes a vibratory plate 351 and a material rail 352. The first end of the material rail 352 is connected to the vibratory plate 351, and the second end is connected to the back of the support plate 330. When the vibratory plate 351 vibrates, it transmits the terminal 01 into the material rail 352 in a certain direction. A pushing mechanism is provided at the second end of the material rail 352, which can push the terminal at the second end of the material rail 352 into the crimping hole.

[0051] When in use, terminal 01 is inserted into the crimping hole, and the stripped end of wire 00 is inserted into terminal 01. Pneumatic clamp 340 clamps wire 00. The fourth motor 321 drives the sliding block 3241 and the drive plate 322 to move downward. The downward movement of the drive plate 322 drives the rotating plate 311 to move forward, causing the pressure block 313 to move inward to press the terminal. Then, the drive plate 322 moves upward, driving the rotating plate 311 to move in the opposite direction, and the pressure block 313 moves outward to release the terminal. Finally, pull out the wire with the crimped terminals.

[0052] In one embodiment, the system further includes a wire detection mechanism 400, which is located next to the stripping and twisting mechanism 200 and is mainly used to detect whether there is wire.

[0053] For example, the wire testing mechanism 400 includes: a tube body 410 and a drive tube body 410, as shown in the example. Figure 2 The drive unit that moves in the Y direction is shown, and the drive unit can be a cylinder; the tube body 410 is equipped with a sensor to sense the wire 00.

[0054] Alternatively, the sensor can be a photoelectric sensor.

[0055] In one implementation, such as Figure 7-8 As shown, it also includes: a wire transmission mechanism 500; the wire transmission mechanism 500 includes: an X-moving component 510, a Y-moving component 520 assembled in the X-moving component 510 and a wire clamping component 530 assembled in the Y-moving component 520; X-movement assembly 510 can be a combination of rail and cylinder, or a lead screw drive assembly; The Y-movement assembly 520 can be a combination of a rail and a cylinder, or a lead screw drive assembly; As long as the clamping assembly 530 can be driven, such as Figure 2 As shown, you can move in the X and Y directions.

[0056] Preferably, such as Figure 7 As mentioned above, both the X-movement component 510 and the Y-movement component 520 are lead screw drive components; When the X-moving component 510 is running, it drives the Y-moving component 520 to move in the X direction, which in turn drives the clamping component 530 to move in the X direction; when the Y-moving component 520 is running, it drives the clamping component 530 to move in the Y direction.

[0057] The wire clamping assembly 530 can be a starter clamp, which is mainly used to clamp the wire 00.

[0058] like Figure 2 As shown, the wire clamping assembly 530 moves in the X direction to switch positions between the wire detection mechanism 400, the wire stripping and twisting mechanism 200, and the terminal crimping mechanism 300; The wire clamping assembly 530 moves in the Y direction to insert or pull the wire into the corresponding position. The wire detection mechanism 400, the wire stripping and twisting mechanism 200, and the terminal crimping mechanism 300 are also included.

[0059] Specifically, the user manually feeds the wire 00, which is then clamped in the wire clamping assembly 530. The X-moving assembly 510 moves the wire clamping assembly 530 to the corresponding wire detection mechanism 400, and the Y-moving assembly 520 pushes the front end of the wire 00 into the wire detection mechanism 400 to detect the presence of the wire 00.

[0060] Next, the Y-moving component 520 operates to pull the wire 00 out of the wire detection mechanism 400; Next, the X moving component 510 moves the wire clamping component 530 to the corresponding stripping and twisting mechanism 200, and the Y moving component 520 pushes the front end of the wire 00 into the stripping and twisting mechanism 200 for cutting and twisting. Next, after the cutting and twisting actions are completed, the Y-moving component 520 pulls out the wire 00. Then, the X-moving component 510 operates to move the wire clamping component 530 to the corresponding crimping terminal mechanism 300; Then, the Y-moving component 520 operates to push the front end of the wire 00 into the crimping terminal mechanism 300 for crimping.

[0061] Finally, the Y-moving component 520 pulls the wire with the crimped terminal out of the crimping terminal mechanism 300, and the user can manually remove the wire with the crimped terminal.

[0062] In one embodiment, it further includes: a control box, a pressure sensor 323 electrically connected to the control box, the pressure received by the pressure sensor 323 when the terminal is crimped is transmitted to the control box, and the control box analyzes the pressure value to determine whether the product is a genuine product or a defective product. The function set in the control box to analyze whether a product is genuine or defective based on its pressure value is part of the software program and will not be specifically defined here.

[0063] For example, products with pressure values ​​within the range of A1-A2 are considered genuine, while products with pressure values ​​outside the range of A1-A2 are considered defective.
