Description

Technical Field

[0001] The invention relates to an automatic winding device, in particular to a connector pin winding device and a winding method of the winding device. Background Art

[0002] With the demand and development of electronic technology and the semiconductor industry, the precision and quality requirements of product electroplating are becoming higher and higher. Taking the gold plating of the workpiece to be plated as an example, more and more products need to change from the original overall gold plating to partial gold plating. Electronic pins (including module pins, telephone communication module pins and headphone pins, etc.), terminal blocks (including connecting columns, PCB board-level connectors and lead pins, etc.) and other connectors need to be gold plated due to the technical requirements of low impedance, low contact resistance, high wear resistance, high conductivity and high carrying current. When the pins of the above connectors are gold plated by electroplating, it is necessary to wrap molybdenum wire around the connector to conduct electricity, and then electroplate the pins.

[0003] Since the pins on the connector are small in size and the gap between two adjacent pins is also small, the method of manually winding the molybdenum wire on the pins has the problems of low efficiency and high cost. In view of the above problems, the applicant intends to design a winding device and winding method that can automatically wind the molybdenum wire on the connector pins to improve efficiency.

[0004] In response to the above problems, a winding device with a bulletin number of 1220996 includes: a wire supply nozzle portion having a wire supply nozzle for guiding a wire, and at least three moving mechanisms for moving the wire supply nozzle portion in a three-dimensional direction; the wire supply nozzle is driven by these moving mechanisms to cause the wire drawn out from the wire supply nozzle to be wound on the winding portion of a workpiece, and the workpiece is assembled on a workpiece fixing fixture. The lead screw mechanism for moving the nozzle portion in a three-dimensional direction includes: a left and right moving mechanism on the base side, a front and back moving mechanism, an up and down moving mechanism, and a left and right moving mechanism on the nozzle side. The front and back moving mechanism is movably supported by the left and right moving mechanism on the base side, and at the same time, the up and down moving mechanism and the left and right moving mechanism on the nozzle side are supported on the front and back moving mechanism. The support plate of the nozzle portion is connected to the up and down moving component of the up and down moving mechanism through the guide rail and the guide rail groove, and is directly connected to the left and right moving component of the left and right moving mechanism through the clamping component and the sliding component. The workpiece fixing fixture used in the above winding device is disc-shaped, the winding stroke of the nozzle part is also circular, and the pin is straight, so that the existing winding device cannot be used for winding the connector pin. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a connector pin winding device and a winding method for the winding device, so as to solve the problem that the existing winding device cannot automatically wind the connector pins.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A connector pin winding device comprises a base and a molybdenum wire pay-off mechanism, wherein the base is mainly composed of a base vertical plate and a base flat plate, the molybdenum wire pay-off mechanism is fixedly mounted on the base vertical plate, and the lower end of the molybdenum wire pay-off mechanism is provided with a molybdenum wire threading head; the molybdenum wire pay-off mechanism comprises a pay-off drum, on which molybdenum wire is wound, the free end of the molybdenum wire passes through the molybdenum wire threading head and extends out of the molybdenum wire threading head, and the molybdenum wire can drive the pay-off drum to rotate under external force; the molybdenum wire pay-off mechanism is assembled on a height and horizontal moving mechanism, and the height and horizontal moving mechanism can drive the molybdenum wire pay-off mechanism to reciprocate and position in the up, down, left and right directions; under the height and horizontal moving mechanism, A forward and backward moving mechanism is provided on the base plate, and a winding plate is detachably mounted on the forward and backward moving mechanism, and the winding plate can be reciprocated and positioned along with the forward and backward moving mechanism; at least one row of connectors is detachably mounted on the winding plate, and the pins of each row of connectors are arranged one by one, and a row of winding posts corresponding to the pins in the connectors are provided on both sides of the head and tail of each row of connectors; the height and horizontal moving mechanisms and the forward and backward moving mechanisms are all connected to a PLC controller, and the forward and backward movement of the winding plate is controlled by the PLC controller, and the up-down and left-right movement of the molybdenum wire unwinding mechanism is controlled, so that the molybdenum wire can move in the three-dimensional direction of the winding plate, and be wound from one side of the winding plate to the other side. In this way, a winding plate is used to assemble the plug connector, so that the plug connector is arranged in a row, and the winding plate is assembled on a forward and backward moving mechanism, so that the winding plate can move back and forth under the drive of the moving mechanism; and the molybdenum wire pay-off mechanism and the molybdenum wire threading head are both assembled on the height and horizontal moving mechanism, and can move left and right and up and down under the drive of the moving mechanism, wherein, when moving up and down, the molybdenum wire threading head and the molybdenum wire threaded therein can be moved downward to the winding plate, or moved upward and away from the winding plate; when moving left and right, the molybdenum wire can be moved left and right, and after cooperating with the forward and backward movement of the winding plate, the molybdenum wire can be moved forward and backward, left and right on the winding plate, and then the plug connector pins on the winding plate can be wound, so as to realize the automatic winding of the butt plug pins. In this winding method, the movement of the molybdenum wire is fully automatically controlled, the control is accurate, and the winding speed is fast. At the same time, the plug connector can be detachably mounted on the winding plate. After the plug connector pins on the winding plate are gold-plated, the molybdenum wire can be removed according to the winding path, and the gold-plated plug connector can be removed to meet the gold-plating requirements of the plug connector.

[0007] Furthermore, a wire clamping group for clamping the molybdenum wire is provided on the left and right sides of the winding plate, each wire clamping group includes two wire clamping heads arranged at intervals, the installation heights of the two wire clamping heads are consistent, and both include a fixed block fixed on the winding plate and / or the base plate and a movable block installed on one side of the fixed block, the movable block is located on the inner side and is arranged close to the base plate; each movable block and the fixed block are connected together through a pin shaft, a torsion spring is sleeved on the pin shaft, and two spring legs of the torsion spring are respectively against the movable block and the fixed block; the movable block and the fixed block each include a clamping part and a pushing part located on both sides of the pin shaft, the clamping part of the movable block and the clamping part of the fixed block have a column at the end, and a rubber sleeve that can rotate under the action of external force is sleeved on each column; each movable block can rotate after being pushed by a pushing mechanism, so that the columns at the ends of the movable block and the fixed block are opened to allow the molybdenum wire to pass through, and after the pushing mechanism moves away from the movable block, the side wall of the rubber sleeve is tightly attached to clamp the molybdenum wire between the two rubber sleeves. In this way, after the wire clamping groups are arranged on both sides of the winding plate, when the molybdenum wire enters from one side of the winding plate, the molybdenum wire can be clamped by the wire clamping group on the entering side to preliminarily position the molybdenum wire. At the same time, since the molybdenum wire is clamped between the two rubber sleeves, the rubber sleeves can rotate under external force and will not affect the next winding movement of the molybdenum wire. In addition, the wire clamping group arranged on the other side of the winding plate can clamp the position after the winding is completed to prevent the molybdenum wire from falling off due to inability to be fixed after the wire is released. At the same time, after the molybdenum wire is sheared, the head of the molybdenum wire can also be clamped to prevent the molybdenum wire from retracting back to the molybdenum wire threading head. The wire clamping head is arranged to be a movable block facing the side of the base vertical plate, which can be pushed by the movable block. After releasing the push, the clamping part is closed and clamped. The setting structure of the wire clamping head is ingenious, and it is flexible to open and close.

[0008] Furthermore, the clamping heads on the left and right sides are arranged in one-to-one correspondence, and the connecting line of the clamping parts of the clamping heads is parallel to the vertical plate of the base; one of the two clamping heads of each clamping group is directly installed on the winding plate, and the other clamping head is installed on the Z-shaped plate on the base plate. In this way, one of the clamping groups is placed on the winding plate, and the other clamping head is placed above the base plate, and the clamping heads of the two clamping groups are in the same width position, which is convenient for simultaneous control. At the same time, after two of the clamping heads are set on the winding plate, when the winding plate is removed, there is a clamping head at the molybdenum wire entry end and the molybdenum wire end on the winding plate to clamp the sheared molybdenum wire end to ensure that the molybdenum wire will not loosen. The clamping head located on the base plate clamps the free end of the molybdenum wire on the wire reel to ensure that the molybdenum wire will not retract and can quickly enter the downward winding process.

[0009] Furthermore, the pushing mechanism includes a movable horizontal plate located at the front end of the base, the movable horizontal plate is connected to a pushing mechanism, and can be reciprocated and positioned forward and backward under the drive of the pushing mechanism; two pushing cylinders corresponding to the pushing parts of the clamping head are installed on the left and right sides of the movable horizontal plate, and the cylinder rod ends of the pushing cylinders pass through the movable horizontal plate. In this way, the movable block of the clamping head is automatically pushed by the pushing mechanism, so that when the molybdenum wire end is clamped during use, it can respond quickly and automatically clamp, thereby ensuring the efficiency of molybdenum wire winding. After the movable horizontal plate is moved outward, the pushing cylinder on the movable horizontal plate is controlled to extend and retract, thereby effectively shortening the stroke of the pushing cylinder and ensuring the stability of the cylinder operation.

[0010] Furthermore, a shearing cylinder is installed between the two left and right pushing cylinders, and a cutter is provided on the cylinder rod of each shearing cylinder, and the cutter is arranged vertically. In this way, the shearing cylinder can move forward quickly after the winding is completed, and cut the molybdenum wire with the cutter, so as to quickly shear the molybdenum wire and effectively improve the efficiency.

[0011] Furthermore, the pushing mechanism includes a pushing cylinder, which is installed in the middle of the base, and the end of the cylinder rod of the pushing cylinder is fixedly connected to the back of the movable horizontal plate; the pushing cylinder and the pushing cylinder are both connected to the PLC controller, and the extension and retraction of the cylinder rods of the pushing cylinder and the pushing cylinder are controlled by the PLC controller. In this way, the controller can set the extension and retraction time of each cylinder through the program, thereby accurately controlling the pushing cylinder and the pushing cylinder.

[0012] Furthermore, the height and horizontal movement mechanism includes a height movement mechanism and a horizontal movement mechanism, the horizontal movement mechanism includes a horizontal motor and a horizontal lead screw, one end of the horizontal lead screw is connected to the output shaft of the horizontal motor, and the other end is installed on the base vertical plate through a bearing seat, and a horizontal sliding sleeve is sleeved on the horizontal lead screw and matched with its thread; the height movement mechanism includes a lead screw mechanism mounting seat and a vertical motor and a vertical lead screw installed at the front end of the lead screw mechanism mounting seat, the lead screw mechanism mounting seat is vertically arranged, the back side of the lead screw mechanism mounting seat is slidingly connected to the front side of the base vertical plate, and the back side of the lead screw mechanism mounting seat is fixedly connected to the horizontal sliding sleeve, and when the horizontal lead screw rotates forward and reversely under the drive of the horizontal motor, it can drive the lead screw mechanism mounting seat The mounting seat slides horizontally and is positioned on the base plate; the output end of the vertical motor is connected to the vertical screw, and a sleeve is provided in the middle of the vertical screw to cooperate with the vertical screw through a thread, and the sleeve can reciprocate up and down and position when the vertical screw rotates forward and backward; the forward and backward moving mechanism includes a moving motor, a moving screw and a winding plate mounting seat, the moving motor is fixed on the base plate, the winding plate mounting seat is located on the base plate, and the lower end is slidably connected to the base plate, the moving screw is perpendicular to the base plate, and is located under the winding plate mounting seat, and an internal thread sleeve is fixedly installed at the bottom of the winding plate mounting seat and sleeved on the moving screw, and the internal thread sleeve can reciprocate back and forth and position when the moving screw rotates forward and backward. In this way, the height moving mechanism is arranged on the horizontal moving mechanism, and at the same time, the wire release mechanism is arranged on the height moving mechanism, which can effectively control the horizontal and height positions of the molybdenum wire threading head, and together with the forward and backward moving mechanism, form a multi-directional change, thereby achieving the winding of the connector pins on the winding plate. Each moving mechanism drives the lead screw to rotate through a motor, thereby driving the connecting parts on the lead screw to move and position. This control method is fast and compact in structure.

[0013] Furthermore, the back of the screw mechanism mounting seat and the base vertical plate, the sliding sleeve and the screw mechanism mounting seat, and the winding plate mounting seat and the base flat plate are all slidably connected by the cooperation of the slide rail and the slider. In this way, the slide rails provided on the base and the mounting seat can guide the slider, and the sliding connection between the slider and the slide rail can effectively ensure the stability of the corresponding parts on each moving mechanism.

[0014] Furthermore, a molybdenum wire guide adjustment mechanism is provided on the molybdenum wire threading head on one side of the wire pay-off drum, and the molybdenum wire guide adjustment mechanism includes a mounting seat fixedly connected to the sliding sleeve, the molybdenum wire threading head is vertically arranged, and the upper end is fixed on the mounting seat, and a vertical threading hole is provided in the middle of the molybdenum wire threading head; a mounting plate is fixedly installed on the side end of the mounting seat, and a threading adjustment frame is fixedly installed on the mounting plate, and a threading hole is correspondingly provided on the left and right sides of the threading adjustment frame, and an upper adjusting block and a lower adjusting block are spaced apart in the middle of the threading adjustment frame, and the left and right sides of the upper adjusting block are slidably connected to the threading adjustment frame, and the lower adjusting block is fixedly installed in the threading adjustment frame; the upper adjusting block can reciprocate and position up and down in the height direction, and a threading gap is formed between the upper adjusting block and the lower adjusting block; the free end of the molybdenum wire on the wire pay-off drum passes through the left side of the threading adjustment frame, the threading gap, and the right side of the threading adjustment frame in turn, and then passes downward into the vertical threading hole of the molybdenum wire threading head, and finally extends out of the molybdenum wire threading head. In this way, the molybdenum wire guiding mechanism can straighten and guide the molybdenum wire, so that the molybdenum wire is first horizontal after being pulled out, and then passes downward through the molybdenum wire threading head to be in a vertical downward state. Among them, the threading holes on the left and right sides of the threading adjustment frame are distributed on the left and right sides and are located at the same height position, which can guide the molybdenum wire pulled out from the wire drum to a horizontal state after being threaded. The upper adjustment block set on the threading adjustment frame can slide up and down and position, so as to adjust the gap size between the upper adjustment block and the lower adjustment block, and regulate the tightness of the molybdenum wire, so that the molybdenum wire is tight but can be pulled, and will not break after being pulled.

[0015] A method for winding a connector pin winding device, the connector pin winding device is as described above, the winding method comprises the following steps: installing a winding plate above a front-rear moving mechanism, and driving the front-rear moving mechanism to move toward a base vertical plate until a clamping group corresponds, driving a height and horizontal moving mechanism to drive a molybdenum wire pay-off mechanism to move downward, and move from one side of the winding plate to the other side, until the molybdenum wire pay-off mechanism moves to the clamping group at the side end of the winding plate, and controlling the molybdenum wire to be clamped in the clamping group and in the initial winding position; at this time, Then continue to control the height and horizontal movement of the horizontal moving mechanism, and the winding plate to move back and forth, so that the molybdenum wire threading head moves on the winding plate according to the set path, and the molybdenum wire is wound on the winding column and the connector pin on the winding plate in sequence until it is wound to the other side of the winding plate. After the winding is completed, the molybdenum wire is clamped to the clamping group on this side and fixed, and the molybdenum wire between the two clamping heads in the clamping groups on both sides is cut off, and the winding plate with the winding completed can be removed to complete the first winding; after the first winding is completed, the above steps are installed and the winding can be repeated many times. In this way, when winding, it is only necessary to assemble the winding plate and start the control device to control each moving mechanism to realize the left and right movement of the molybdenum wire threading part. Combined with the front and back movement of the winding plate, the molybdenum wire is continuously moved relative to each other in the left and right directions, and the connector pins and the winding column are relatively moved in the front and rear directions, so as to realize the winding of the rows of connector pins in the process of continuous change of the four directions.

[0019] like Figure 1-Figure 5As shown, the connector pin winding device provided in this embodiment includes a base 1 and a molybdenum wire pay-off mechanism 2, wherein the base 1 is mainly composed of a base upright plate 12 and a base flat plate 11 (the base flat plate 11 is located below the base upright plate 12, is arranged perpendicular to the base upright plate 12, and is L-shaped after being connected to the base upright plate 12 by fasteners), the molybdenum wire pay-off mechanism 2 is fixedly installed on the base upright plate 12, and the lower end of the molybdenum wire pay-off mechanism 2 is provided with a molybdenum wire threading head 23; the molybdenum wire pay-off mechanism 2 includes a pay-off drum 21, on which molybdenum wire is wound, the free end of the molybdenum wire passes through the molybdenum wire threading head 23 and extends out of the molybdenum wire threading head 23, and the molybdenum wire can drive the pay-off drum 21 to rotate under external force; the molybdenum wire pay-off mechanism 2 is assembled on a height and horizontal moving mechanism 3, and the height and horizontal moving mechanism 3 can drive the molybdenum wire pay-off mechanism 2 to reciprocate and position in the up, down, left and right directions; in the height and horizontal moving mechanism 3 A forward and backward moving mechanism 4 is provided on the lower and base flat plates 11, and a winding plate 5 is detachably mounted on the forward and backward moving mechanism 4, and the winding plate 5 can be reciprocated and positioned with the forward and backward moving mechanism 4; two rows of connectors 51 are detachably mounted on the winding plate 5, and two adjacent rows of connectors 51 are arranged in a one-to-one correspondence (for ease of control, the spacing between two adjacent connectors 51 on each row of connectors 51 is consistent), and a plurality of winding posts 52 corresponding to the pins of the connectors 51 are provided between the two adjacent rows of connectors 51 and / or on the outsides of the two adjacent rows of connectors 51, and the winding posts are arranged in a one-to-one correspondence with the connectors; the height and horizontal moving mechanism 3 and the forward and backward moving mechanism 4 are all connected to a PLC controller, and the forward and backward movement of the winding plate 5 is controlled by the PLC controller, and the up-down and left-right movement of the molybdenum wire unwinding mechanism 2 is controlled, so that the molybdenum wire can move in the three-dimensional direction of the winding plate 5, and be wound from one side of the winding plate 5 to the other side.

[0020] Specifically, the winding board in this embodiment is provided with two rows of mounting grooves, and the mounting grooves match the shape of the connectors, and the connectors are fixed in the mounting grooves by plugging. A plurality of connectors are arranged at equal intervals on the winding board, and the connectors are arranged in rows with the same installation height, so that it can be ensured that after the pins of each connector correspond to each other, the pins on each two adjacent connectors are in the same row, so that it is convenient for the moving mechanism on the winding device to drive the winding part to move horizontally or longitudinally, so that it can adapt to the moving path of the winding part and realize automatic winding. At the same time, each connector is assembled on the winding board by plugging. When installing, press the connector downward. When the processing is completed and disassembled, just pull out the connector with force. Both installation and disassembly are relatively convenient and quick. The winding post arranged near the connector can be used in the winding process. After winding one of the connector pins, when winding the next connector, first bypass the winding post and then wind the next connector, so as to guide the winding direction. In addition to the guide, every two winding posts correspond to the two ends of a connector and correspond to the pins of the connector, so that when winding, a certain pulling force can be formed on the winding entry position of each connector and the winding completion position of each connector, so that each connector is evenly wound, and the molybdenum wires between two adjacent connectors are not directly wound and do not affect each other.

[0021] When the winding device in this embodiment is used, after the free end of the molybdenum wire on the wire pay-off drum 21 in the molybdenum wire pay-off mechanism 2 passes through the molybdenum wire threading head 23, it moves with the molybdenum wire threading head 23, and the lower end is arranged facing the base plate 11. When winding, if the molybdenum wire extending from the molybdenum wire threading head 23 is directly wound on the winding column 52 on the winding plate 5 or the pin of the plug 51, when the winding is completed, the molybdenum wire entry end and the molybdenum wire winding end are cut, if the molybdenum wire is not stretched and tightened at the two corresponding positions, there will be a problem of inconvenience in cutting. At the same time, when the winding plate 5 is removed and the winding plate 5 is used for the gold plating process, if the end of the molybdenum wire is not clamped and fixed, it is easy to spread out. Therefore, in order to facilitate cutting and keep the winding state of the molybdenum wire to prevent it from loosening, the molybdenum wire needs to be clamped and fixed at the position where it enters the winding plate 5 and the position where it is pulled out after the winding is completed.

[0022] In order to solve the above problems, in this embodiment, a clamping group for clamping the molybdenum wire is provided on both the left and right sides of the winding plate 5, such as Figure 4As shown, each clamping group includes two clamping heads 6 arranged at intervals, and the installation height of the two clamping heads 6 is consistent. They all include a fixed block 61 fixed to the winding plate 5 and one side of the winding plate 5, and a movable block 62 installed on one side of the fixed block 61. The movable block 62 is located on the inner side and is arranged close to the base vertical plate 12; each movable block 62 and the fixed block 61 are connected together through a pin shaft 63, and a torsion spring 64 is sleeved on the pin shaft 63. The two spring legs of the torsion spring 64 are respectively against the movable block 62 and the fixed block 61; the movable block 62 and The fixed block 61 includes a clamping part and a pushing part located on both sides of the pin shaft. The clamping part of the movable block 62 and the clamping part of the fixed block 61 have a column 65 at the end. A rubber sleeve 66 that can rotate under the action of external force is sleeved on each column 65. Each movable block 62 can rotate after being pushed by a pushing mechanism 7, so that the columns 65 at the ends of the movable block 62 and the fixed block 61 are open for the molybdenum wire to pass through. After the pushing mechanism 7 is away from the movable block 62, the side wall of the rubber sleeve 66 is tightly attached to clamp the molybdenum wire between the two rubber sleeves 66. The structure of the above-mentioned clamp head 6 is similar to the clamp structure in life, but with a rubber sleeve 66, the rubber sleeve 66 is round, and the column 65 is also cylindrical, so that the molybdenum wire can be continuously wound after the wire is released from the wire reel 21 during the winding process without affecting the wire.

[0023] To ensure that the winding plate 5 can still clamp the wire end portion after the winding plate 5 is disassembled, one of the two clamping heads 6 of each clamping group is directly mounted on the winding plate 5, and the other clamping head 6 is mounted on the Z-shaped plate on the base plate 11 (the lower end of the Z-shaped plate is fixedly mounted on the base plate 11 by fasteners). Of course, in a specific implementation, both clamping groups can be assembled on the winding plate 5, which requires increasing the length of the winding plate 5 and the cost of the winding plate 5 will be slightly higher.

[0024] like Figure 5 As shown, the pushing mechanism 7 in this embodiment includes a movable horizontal plate 71 located at the front end of the base 1, and the movable horizontal plate 71 is connected to a pushing mechanism 8, and can be reciprocated and positioned under the drive of the pushing mechanism 8; two pushing cylinders 72 corresponding to the pushing parts of the clamping head 6 are installed on the left and right sides of the movable horizontal plate 71, and the cylinder rod ends of the pushing cylinders 72 pass through the movable horizontal plate 71. A shearing cylinder 73 is installed between the two pushing cylinders 72 on the left and the two pushing cylinders 72 on the right, and a cutter 74 is provided on the cylinder rod of each shearing cylinder 73, and the cutter 74 is vertically arranged. Specifically, the cutter 74 in this embodiment can be detachably installed at the end of the cylinder rod of the shearing cylinder 73, and can be replaced according to the usage.

[0025] Specifically, in order to realize automatic control during shearing and pushing, the pushing mechanism 8 in this embodiment includes a pushing cylinder 81, which is installed in the middle of the base plate 12, and the end of the cylinder rod of the pushing cylinder is fixedly connected to the back of the movable cross plate 71; in order to facilitate the clamping control and shearing control of the molybdenum wire, improve the clamping and shearing efficiency of the molybdenum wire, and increase the automatic control of the winding device, the pushing cylinder and the pushing cylinder 72 are connected to the PLC controller, and the extension and retraction of the cylinder rods of the pushing cylinder and the pushing cylinder 72 are controlled by the PLC controller.

The sliding sleeve 36 can move back and forth and position when the vertical screw rod 35 rotates forward and reversely; the forward and backward moving mechanism includes a moving motor 41, a moving screw 42 and a winding plate mounting seat 43. The moving motor 41 is fixed on the base plate, and the winding plate mounting seat 43 is located on the base flat plate, and the lower end is slidably connected to the base flat plate. The moving screw 42 is perpendicular to the base plate and is located under the winding plate mounting seat 43. An internal threaded sleeve 44 is fixedly installed on the bottom of the winding plate mounting seat 43 and is sleeved on the moving screw 42. The internal threaded sleeve 44 can move back and forth and position when the moving screw rotates forward and reversely.

[0027] The back of the screw mechanism mounting seat 33 and the base vertical plate 12, the sliding sleeve 36 and the screw mechanism mounting seat 33, and the winding plate mounting seat 43 and the base plate 11 are all connected by sliding through the cooperation of the sliding rails and the sliders. Specifically, the sliding rails are provided on the base vertical plate 12, the upper and lower sides of the horizontal screw 32, the middle part of the base plate 11, and the left and right sides of the movable screw 42, that is, the horizontal moving mechanism and the front and rear moving mechanism 4 are provided with two sliders that cooperate with the sliding rails. A vertically arranged sliding rail is provided on the front of the screw mechanism mounting seat 33, which is used to cooperate with the slider on the back of the sliding sleeve 36. This arrangement can effectively ensure the smooth operation of the left and right moving mechanism and the front and rear moving mechanism 4, and form support for the screw mechanism mounting seat 33 and the winding plate 5.

[0028] During the pay-off process, if the pay-off tension of the molybdenum wire changes and cannot be adjusted, the subsequent threading action of the molybdenum wire will be affected; therefore, in order to ensure that the molybdenum wire has appropriate tension during pay-off and can be guided to the threading head and threaded with the molybdenum wire through the threading head, it is necessary to be able to adaptively adjust the molybdenum wire clamping tension according to actual use. To meet the above purpose, a molybdenum wire guide adjustment mechanism (such as a wire guide adjustment mechanism) is also provided on one side of the pay-off drum 21 and the molybdenum wire threading head 23. Figure 4 As shown in the figure, the molybdenum wire guide adjustment mechanism includes a mounting seat 22 fixedly connected to the sliding sleeve 36, the molybdenum wire threading head 23 is vertically arranged, and the upper end is fixed on the mounting seat 22, and a vertical threading hole 26 is provided in the middle of the molybdenum wire threading head 23; a mounting plate 24 is fixedly installed on the side end of the mounting seat 22, and a threading adjustment frame 25 is fixedly installed on the mounting plate 24, and a threading hole 26 is correspondingly provided on the left and right sides of the threading adjustment frame 25, and an upper adjustment block 27 and a lower adjustment block 27 are provided in the middle of the threading adjustment frame 25. The node block 28 and the left and right sides of the upper adjustment block 27 are slidably connected to the threading adjustment frame 25, and the lower adjustment block 28 is fixedly installed in the threading adjustment frame; the upper adjustment block 27 can reciprocate and position up and down in the height direction, and a threading gap is formed between the upper adjustment block 27 and the lower adjustment block 28; the free end of the molybdenum wire on the wire-releasing drum 21 passes through the left side of the threading adjustment frame 25, the threading gap, and the right side of the threading adjustment frame 25 in turn, and then passes downward into the vertical threading hole 26 of the molybdenum wire threading head 23, and finally extends out of the molybdenum wire threading head 23.

[0029] Specifically, the threading adjustment frame in this embodiment is rectangular, and a vertically arranged threaded hole is provided in the middle of the upper side of the threading adjustment frame, and an adjusting bolt is provided in the threaded hole and matched with the threaded hole, and the lower end of the adjusting bolt is connected to the upper adjustment block, and the adjusting bolt can rotate under the action of an external force. The upper adjustment block and the lower adjustment block are both rectangular, and a U-shaped slider is provided on both sides of the upper adjustment block, and one side of the opening of the U-shaped slider faces the side end of the threading adjustment frame and matches the side end of the threading adjustment frame.

[0030] During the molybdenum wire pay-off process, the free end of the molybdenum wire will continuously change its position up and down according to the winding height of the molybdenum wire. If the molybdenum wire is directly inserted into the threading hole of the threading adjustment frame, the angle between the molybdenum wire and the threading hole on the left side of the threading adjustment frame will change continuously due to the different heights of the molybdenum wire lead-out, and the tension of the molybdenum wire lead-out will also change continuously. In order to make its tension relatively stable in the threading adjustment frame position and to better guide the molybdenum wire, a wire plate 29 is further provided on the mounting plate 24 and between the threading adjustment frame 25 and the pay-off drum 21. The wire plate 29 is fixedly mounted on the mounting plate 24, and the upper end is vertically bent upward to form a bending portion, and a through hole is provided on the bending portion. After the molybdenum wire is led out from the pay-off drum 21, it passes through the through hole on the wire plate 29, and then is inserted into the threading adjustment frame 25, and finally is inserted downward along the right outer wall of the threading adjustment frame 25 into the molybdenum wire threading head 23.

[0031] In order to facilitate the threading and pulling of the molybdenum wire in the molybdenum wire threading head 23, an adjustment hole 231 is provided on the molybdenum wire threading head 23 for a finger to insert and pull the molybdenum wire, and a vertically arranged threading needle tube 232 is provided under the adjustment hole 231. The threading needle tube has a vertical threading through hole connected to the adjustment hole, and the diameter of the vertical threading through hole is slightly larger than the diameter of the molybdenum wire. The threading needle can guide the molybdenum wire more accurately after threading, so that the molybdenum wire can be more easily aligned with the gap between the pins during the winding process, and at the same time, it can effectively avoid slight deviations in the position of the molybdenum wire.

[0032] To facilitate the replacement of the winding plate 5, an operating platform is fixed at the front end of the base 1 and in front of the base plate 11, on which the winding plate 5 for replacement is placed. At the same time, for ease of operation, operating buttons such as power on and power off are also provided on the operating platform.

[0033] The winding method of the above connector pin winding device comprises the following steps: installing the winding plate 5 above the front-rear moving mechanism 4, and driving the front-rear moving mechanism 4 to move in the direction of the base vertical plate 12 until the clamping group corresponds, driving the height and horizontal moving mechanism 3 to drive the molybdenum wire release mechanism 2 to move downward, and move from one side of the winding plate 5 to the other side until the molybdenum wire release mechanism 2 moves to the clamping group at the side end of the winding plate 5, and controlling the molybdenum wire to be clamped in the clamping group and in the initial winding position; at this time, continue to control the height and horizontal moving mechanism 3 to move the molybdenum wire release mechanism 2 downward, and move from one side of the winding plate 5 to the other side, until the molybdenum wire release mechanism 2 moves to the clamping group at the side end of the winding plate 5, and control ... and drive the molybdenum wire release mechanism 2 to move to the clamping group at the side end of the winding plate 5, and control the molybdenum wire to be clamped in the clamping group and in the initial winding position; at this time, continue to control the height and horizontal moving mechanism 3 to move the molybdenum wire release mechanism 2 downward, and move from one side of the winding plate 5 to the other side, and drive the moly The structure 3 moves horizontally and the winding plate 5 moves back and forth, so that the molybdenum wire threading head 23 moves on the winding plate 5 according to the set path, and the molybdenum wire is wound around the winding column 52 and the pin of the connector 51 on the winding plate 5 in sequence until it is wound to the other side of the winding plate 5. After the winding is completed, the molybdenum wire is controlled to be clamped to the clamping group on this side and fixed, and the molybdenum wire between the two clamping heads 6 in the clamping groups on both sides is cut off, and the winding plate 5 with the winding completed can be removed to complete the first winding; after the first winding is completed, the above steps are installed and the winding can be repeated many times.

[0034] Specifically, the winding path in this embodiment is mainly serpentine winding, with the initial position on the left side, first winding from the connector near the rear side of the device, then winding from the back to the front to the front row of winding posts, then winding to the right to the adjacent winding posts, winding from the front to the back, and so on, from left to right, one by one. The next winding is from the right side of the winding board to the left side.

[0035] When winding, the molybdenum wire can be set to be wound around one row, then around the winding post 52 corresponding to the end of the row, then around the winding post 52, and then around the winding post 52 of the adjacent row and the connector pins. Of course, when winding, it is also possible to first wind around one row of connector pins and then around the second row. The specific path of the winding is set by setting the program.

[0036] In addition, when the height and horizontal moving mechanism 3 is driven to drive the molybdenum wire unwinding mechanism 2 to correspond to the wire clamping group to clamp the molybdenum wire, the push cylinder corresponding to the wire clamping group on this side can be controlled to drive the movable cross plate 71 to move forward, and after moving forward to the specified position, the push cylinder is closed, and the cylinder rod of the pushing cylinder 72 on the corresponding side is started to move forward, pushing the movable block 62 in the corresponding wire clamping group to rotate, and the column 65 on the movable block 62 is in an open state; at this time, the horizontal moving mechanism of the height and horizontal moving mechanism 3 is immediately driven to move horizontally, so that the molybdenum wire threading head 23 connected thereto is translated, and the molybdenum wire is placed in the wire clamping group. between the columns 65; after bypassing the two clamping heads 6 of the clamping group, the cylinder rod in the pushing cylinder 72 is driven to retract, and at the same time, the cylinder rod of the pushing cylinder is driven to retract until the winding is completed, and then the pushing cylinder is driven to move the cylinder rod forward, and then the pushing cylinder 72 is driven to push the clamping group on the other side. After the movable block 62 in the clamping group is opened, the horizontal moving mechanism is driven to continue to move horizontally to clamp the molybdenum wire, and finally the cylinder rod of the pushing cylinder 72 is driven to retract, and the cylinder rods of the two shearing cylinders are driven forward to shear the part between the clamping groups on both sides of the molybdenum wire; after the shearing is completed, the pushing cylinder is driven to retract.

[0037] The automatic clamping and shearing mechanism can preliminarily fix and guide the molybdenum wire, fix the end of the molybdenum wire after the molybdenum wire is wound, and shear the clamping parts on both sides of the winding plate 5 to facilitate the removal of the winding plate 5.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
