[0050] like Figure 3 、 Figure 12As shown, the present invention provides a fully automatic forming production machine for twist needle needles, including a wire feeding device 1, a cutting device 2, a welding device 3, a roughening device 4, a plate passing device 5, a detection and sorting device 6, a needle transfer device 7 and a control device 8. The wire feeding device 1 is used to feed the cable to be cut of a length corresponding to the required needle head into the cutting device; the cutting device 2 cuts the cable to be cut into needle heads of the required length; the welding device 3 includes a welding head 31 and a needle head control device for feeding the needle head cut by the cutting device into the welding position of the welding head and realizing needle head rotation control; the roughening device 4 is used to roughen the needle head after welding; the plate passing device 5 is used to adjust the size of the roughened part of the needle head after roughening; the detection and sorting device 6 is used to detect and sort the quality of the needle head after passing the plate; the needle head transfer device 7 is used to control the transfer of the needle head between the front and rear workstations of the welding device, roughening device, plate passing device, and detection and sorting device; and the control device is used to control the coordinated operation of the wire feeding device 1, cutting device 2, welding device 3, roughening device 4, plate passing device 5, detection and sorting device 6, and needle head transfer device 7. The above structure can realize the full automation of twist needle needle processing without human intervention and high processing efficiency.

[0051] The wire feeding device 1 can be implemented in a variety of structures. For example, it can include only a straightener 11 for straightening the cable to be cut and a wire feeding roller device 15 for feeding the cable to be cut to a length corresponding to the required needle into the cutting device. For another example, based on the above-mentioned straightener 11 and wire feeding roller device 15 structure, it also includes a first clamping plate device 12, a second clamping plate device 13 and a buffer 14 arranged between the straightener and the wire feeding roller device. The buffer 14 is used to adjust and detect the length of the cable to be cut between the first clamping plate device 12 and the wire feeding roller device 15; the second clamping plate device 13 is placed between the first clamping plate device 12 and the buffer 14 to pull the cable to be cut toward the buffer 14.

[0052] The specific structure of the wire feeding device 1 can be referred to Figure 3 、 Figure 4 .

[0053] The straightener 11 adopts a roller structure with two rows of rollers staggered from each other, and the distance between the two rows of rollers can be adjusted.

[0054] The first clamping plate assembly 12 includes a first fixed clamping plate 122, a first movable clamping plate 123, and a first straightening control component 121. The first movable clamping plate is connected to the first straightening control component 121. The first straightening control component controls the movement of the first movable clamping plate to adjust the distance between the first movable clamping plate and the first fixed clamping plate 122, thereby controlling the tightening and loosening of the cable. The first straightening control component 121 can be implemented using a cylinder or a screw rod and motor.

[0055] The second clamping plate device 13 includes a second fixed clamping plate 132, a second movable clamping plate 133, a second straightening control component 131, a moving block 134 and a pushing device 135. Similarly, the second straightening control component 131 can be implemented by a cylinder or a screw rod plus a motor; the pushing device 135 can be implemented by a cylinder or a screw rod plus a motor; the second fixed clamping plate 132 and the second straightening control component 131 are fixed on the moving block; the second movable clamping plate 133 is fixed on the second straightening control component 131 to adjust the distance between the second fixed clamping plate 132 and the second movable clamping plate 133 to achieve control of clamping and loosening the cable; the moving block 134 is fixed on the pushing device 135, and the pushing device 135 realizes control of the movement of the moving block, thereby controlling it to pull the cable toward the buffer 14 when the second fixed clamping plate 132 and the second movable clamping plate 133 clamp the cable. The signal control end of the first straightening control component 121 and the signal control end of the second straightening control component 131 are both connected to the control device.

[0056] The buffer 14 includes a buffer rod that can rotate about one end, a counterweight fixed to the other end of the buffer rod, and a detection device for detecting the height position of the other end of the buffer rod. When the detection device detects that the height of the other end of the buffer rod is greater than or equal to a height threshold, the control device controls the second clamping plate device 13 to pull the cable to be cut toward the buffer 14. The detection device can be implemented in various ways, such as a photoelectric sensor or an angle sensor. The photoelectric sensor is installed at a certain location to detect the presence of a counterweight or buffer rod at that location. When the absence of a counterweight or buffer rod is detected at that location, it can be determined that the end of the buffer rod with the counterweight has been raised to a height greater than or equal to a height threshold due to the cable pulling. The angle sensor is installed at the rotatable end of the buffer rod to monitor its rotation amount. When the rotation angle of one end of the buffer rod is greater than an angle threshold, it can be determined that the end of the buffer rod with the counterweight has been raised to a height greater than or equal to a height threshold due to the cable pulling. The signal output end of the detection device is connected to the control device.

[0057] The wire feeding roller device 15 adopts the structure of two wire feeding rollers and a wire feeding drive device. The wire feeding drive device can adopt a motor to drive one of the two wire feeding rollers to rotate so as to realize wire feeding. The control end of the motor is connected to the control device.

[0058] Specifically, during operation, the cable 91 to be cut is hung on the material rack in the form of a cable drum 9. The cable passes through the straightener 11, the first clamping plate device 12, the second clamping plate device 13, and the buffer 14 in sequence and then enters the wire feeding roller device 15. In the initial state, the first clamping plate device clamps the cable to prevent interference between the front and the back. In the process of the wire feeding roller device 15 feeding the wire to the rear-end cutting device, the cable between the first clamping plate device and the wire feeding roller device 15 becomes shorter. Under the action of the cable tension, one end of the counterweight block of the buffer rod is lifted. After the detection device detects that it has been lifted to a certain height, the control device first controls the first clamping plate device 12 to release the cable, and then controls the second clamping plate device 13 to clamp the cable. After that, one end of the buffer moves to pull the cable. At this time, it moves downward under the action of the counterweight block. After the detection device detects that the buffer has returned to its original position, it controls the first clamping plate device to clamp the cable and the second clamping plate device 13 to release the cable.

[0059] The cutting device can be realized by using a flat cutter or a round hole cutter. Figure 5 The figure shows a structure using a circular hole cutter, comprising a left cutter 21, a right cutter 22, and a cutting control device 23 that controls the vertical movement of the left cutter 21 to cut the cable. The cutting control device is connected to the control unit. The cutting device cuts the cable 91 to be cut into sections of needles 92. The cutting control device 23 can be a cylinder, a screw rod, or a motor.

[0060] Needle control devices such as Figure 6As shown, it includes a welding clamp 32, a rotation control device 33 for controlling the rotation of the welding clamp 32, and a position control device 34; the position control device controls the movement of the welding clamp 32 at the cutting device 2 and the welding head 31, and makes the needle lengths on both sides of the welding clamp 32 equal when the welding clamp 32 clamps the needle at the cutting device 2. During the processing of the twist needle needle, since both ends of the needle need to be welded, the position accuracy of the welding position is a difficult point. During laser welding, the needle position must be placed at the laser focal length, and the error must not exceed ±0.03mm. The accuracy requirements are very high, and if there is any deviation, the welding will fail. Of course, when welding the first end of the needle, the required accuracy can be easily achieved by adjusting the position of the welding clamp 32. However, after rotating the needle, there will be errors in the welding of the second end. This solution uses a position control device to control the needle 92 when it is clamped at the cutting device, so that the needle lengths on both sides of the welding clamp 32 are equal. That is, after welding the first end of the needle, the needle is directly controlled to rotate 180 degrees, which can ensure that the height of the second end and the center of the needle are the same as the first end, thereby improving the quality of laser welding. The position control device is a three-axis manipulator, which realizes the control of the X-axis, Y-axis and Z-axis. The X-axis, Y-axis and Z-axis of the position control device can all be realized using the existing screw plus motor structure. The X-axis here is preferably consistent with the direction of the cable pulled by the aforementioned second clamping plate device 13. The control ends of the rotating device, the position control device and the welding clamp 32 are all connected to the control device. The rotation control device 33 controls the clamping jaws of the welding clamp 32 to be in an up and down state, and the position control device controls the welding clamp to move to the appropriate position of the cutting device first, so that the length of the needles on both sides of the welding clamp 32 is equal, that is, the distance from one side to the cutting surface of the cutting device is equal to the distance from the other side to the other cut end of the needle. The welding clamp 32 controls the two clamping jaws to clamp the needle. After the cutting device completes cutting, the position control device 34 controls the welding clamp 32 to move to the welding position of the welding head 31. The rotation control device 33 controls the welding clamp 32 to rotate 90 degrees, so that the needle in the horizontal state is in a vertical state, and the welding of the first end starts; after the welding is completed, the rotation control device 33 controls the welding clamp 32 to rotate 180 degrees, and the welding of the second end starts.

[0061] The roughening device 4 includes a clamping portion for securing the first end of the needle and a roughening portion for limiting the roughening of the second end of the needle. The roughening portion includes a roughening head 41 for limiting the position of the second end of the needle, a detection device for detecting contact between the second end of the needle and the roughening head, and a roughening control component for controlling the roughening head to move a preset distance along the needle diameter toward the clamping portion after the detection device detects contact between the second end of the needle and the roughening head. Controlling the roughening amount is also a challenge in the processing of twist needles. The roughening amount refers to the amount of position pushed forward by the lower tapered hole during roughening, which directly determines the size of the bulge. However, since the needle length will have significant errors after cutting, welding, and clamping, roughening according to a fixed roughening amount will inevitably lead to errors in the bulge size due to the error in the needle length itself. The longer needle will change size and become thicker, while the shorter needle will change size and become smaller, resulting in poor product consistency. The roughening part of the solution of the present invention adopts a detection device to detect the contact between the second end of the needle and the roughening head. After the needle is placed in the roughening head and contacts the roughening head, the roughening head is controlled to move a preset distance along the needle diameter toward the clamping part. Since the moving distance of the roughening part is uniform for all needles, the bulge diameter error caused by the error in the needle length can be effectively eliminated, the consistency of the bulge is improved, and the performance of the needle product is effectively improved.

[0062] The roughening section includes a roughening head, a detection device, and a roughening control component. The roughening head is used to limit the second end of the needle; the detection device is used to detect contact between the second end of the needle and the roughening head; and the roughening control component is used to control the roughening head to move a preset distance along the needle diameter toward the clamping portion after the detection device detects contact between the second end of the needle and the roughening head. This preset distance is consistent with the roughening amount of the needle. With this structure, even if there is a length error in the needle, the roughening amount can be guaranteed to be consistent, effectively ensuring product quality.

[0063] Specifically, the pier head 412 can be made of Figure 7 、 Figure 8 In the structure described above, in order to facilitate the insertion of the needle into the roughening head 412, a conical groove 4121 for placing the needle can be provided on the top of the roughening head 412.

[0064] Based on the different structures of the pier head 412, the setting of the detection device may also be different. Figure 7 、 8The structure of the upsetting head 412 described above is characterized by a detection hole provided on the upsetting head, one end of which communicates with the tapered groove 4121. The detection device includes a core rod 422 placed in the detection hole, a sensor 421 for detecting the contact between the needle and the core rod, and a connector 423 for connecting the core rod 422 and the sensor 421. One end of the core rod 422 is placed in the tapered groove or at the bottom of the tapered groove to ensure contact and compression with the needle. The sensor 421 may be a force sensor.

[0065] The upsetting control component of the upsetting head 412 can be implemented using a variety of structures, such as pneumatic or hydraulic cylinder transmission. To precisely control the movement of the upsetting head 12, a screw drive is preferred. The sensor and upsetting head are fixed to a fixed member 424. The upsetting control component includes a second screw and a fourth drive component for rotating the screw. The fixed member is screwed onto the second screw. The fourth drive component can be implemented using a motor, or a combination of a motor and a reducer.

[0066] There are many ways to realize the clamping part, such as using a structure with two semicircular clamps; in order to realize the control of the pier position, the following methods can be used: Figure 7 The structure shown includes a first clamping member for clamping the first end of the needle 92 and a second clamping member placed between the first clamping member and the upsetting head and used to adjust the upsetting position.

[0067] When the second clamping structure is adopted, the first clamping member includes two first clamping jaws 431 arranged opposite to each other and a first driving component for controlling the opening and closing state of the two first clamping jaws. The second clamping member includes two second clamping jaws 432 arranged opposite to each other, a second driving component for controlling the opening and closing state of the two second clamping jaws, and a third driving component for controlling the second driving component and the second clamping jaw to move in a direction perpendicular to the opening and closing direction of the two second clamping jaws. The third driving component can be implemented using a variety of structures, such as cylinder transmission and hydraulic cylinder transmission. In order to achieve precise adjustment of the piercing position, the third driving component adopts a screw transmission. In this case, the third driving component includes a motor and a first screw connected to the output end of the motor, and the second driving component is connected to the first screw through a screw hole.

[0068] Like the fourth drive component, the third drive component can be implemented as a motor; or a combination of a motor and a reducer. The first drive component, the second drive component, the third drive component, and the control end of the first drive component are all connected to a control device. The control device is used to achieve the coordinated operation of the first drive component, the second drive component, the third drive component, and the fourth drive component to achieve automatic needle thickening.

[0069] With the above structure, the control device controls the first driving component to drive the first clamping jaw 431 to clamp the first end of the needle, and the third driving component drives the second clamping jaw to move up to a suitable position. After the precise adjustment of the roughening position is achieved, the second driving component drives the second clamping jaw to clamp the needle. At this time, the fourth driving component drives the roughening head 412 to move up. When the roughening head 412 moves up to the core rod 422 and contacts the needle, the sensor detects the change in force. At this time, the fourth driving component continues to drive the roughening head 412 to move up a preset distance to complete the roughening.

[0070] The plate passing device 5 is as follows Figure 9 As shown, the device comprises a plate-passing clamp 51, a plate 52 with a hole structure, and a plate-passing control device for controlling the axial movement of the plate 52 along the hole structure. The depth of the hole in the plate 52 is greater than the roughening amount of the needle. The control ends of the plate-passing clamp 51 and the plate-passing control device are both connected to the control device. The plate-passing clamp 51 clamps the first end of the needle, while the plate-passing control device controls the vertical movement of the plate 52, thereby passing the hole of the second end of the needle and the roughening section, and achieving uniform dimensions of the roughening section.

[0071] Detection and sorting device 6 Figure 10 As shown, the system comprises a rotatable detection jaw 61, a detection rotation drive device for driving the detection jaw 61 to rotate, an image acquisition device 63 for acquiring image information of the needle held by the jaw, a sorting box 62, and a sorting box control device 64 for controlling the position of the sorting box 62. The sorting box control device 64 can be a cylinder or a screw-and-motor structure. The control end of the detection jaw 61, the signal output end of the image acquisition device 63, the control end of the detection rotation drive device, and the control end of the sorting box control device 64 are all connected to the control device. The detection rotation drive device drives the detection jaw 61 to rotate, enabling multi-directional image acquisition of the needle. The control device performs image recognition based on the needle image information collected through the image acquisition process to conduct a comprehensive quality assessment and determine whether the needle processing quality is qualified or unqualified. Based on the quality assessment results, the sorting box control device 64 is controlled to drive the sorting box 62 to move, causing the needle to fall into the corresponding box body.

[0072] The needle transfer device 7 can be implemented in a variety of structures. In order to simplify the structure, the following structures can be used: Figure 11The structure shown. It includes a first fixed plate 71, a second fixed plate 72, a first transfer clamp 73, a second transfer clamp 74, a third transfer clamp 75, a first transfer control unit 76 and a second transfer control unit 77. The first transfer clamp 73, the second transfer clamp 74 and the third transfer clamp 75 are fixed to the second fixed plate 72 in sequence, and the center of the first transfer clamp 73, the second transfer clamp 74 and the third transfer clamp 75 is on the same straight line and the distance between two adjacent transfer clamps is equal. The center here refers to the center of the clamping position of the first transfer clamp 73, the second transfer clamp 74 and the third transfer clamp 75 when they are in a clamping state. The second transfer control unit 77 is fixed to the first fixed plate 71 and connected to the second fixed plate 72 to control the second fixed plate 72 to move in a direction away from or close to the welding device 3, the roughening device 4, the plate passing device 5 and the detection and sorting device 6, and this direction is parallel to the Y axis of the needle control device. The first transfer control unit 76 is connected to the first fixed plate 71 to control the movement of the first fixed plate 71 in a direction perpendicular to or away from the welding device 3. The second transfer control unit 77 and the first transfer control unit 76 can be implemented using a pneumatic cylinder or a screw-and-motor structure, with the direction parallel to the X-axis of the needle control device. Accordingly, the distance between the welding head 31 of the welding device 3 and the center of the clamping portion of the upsetting device 4, the distance between the center of the clamping portion of the upsetting device 4 and the center of the plate-passing jaw 51 of the plate-passing device 5, and the distance between the center of the plate-passing jaw 51 of the plate-passing device 5 and the center of the detection jaw 61 of the detection and sorting device 6 are equal, and are equal to the spacing between two adjacent transfer jaws.
