Description

Technical Field

[0001] The invention relates to a winding device, in particular to a molybdenum wire winding plate used in the molybdenum wire 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 current carrying capacity. When the pins of the above connectors are gold plated by electroplating, it is necessary to wrap molybdenum wire around the connector, and after the molybdenum wire conducts electricity, the pins are electroplated, and the molybdenum wire is removed after the electroplating is completed.

[0003] At present, the molybdenum wires are wound around the pins of the connector manually one by one. During the winding process, the gap between the connector pins is very small, which is particularly time-consuming and laborious. In view of the above problems, the applicant intends to design a winding device to automatically wind the connector pins to improve the winding efficiency.

[0004] The existing winding device is mainly used for winding motor coils, inductor coils, square transformers, etc., including a wire supply part and a moving mechanism that drives the wire supply part to move in multiple directions. A workpiece fixing fixture is provided under the wire supply part. The workpiece fixing fixture is generally disc-shaped, and a plurality of winding posts distributed in a circle are provided on it. The workpiece fixing fixture is driven to rotate to continuously wind the wire. The winding posts in the above-mentioned fixed winding workpiece fixture are distributed in a circle (the pins in the connector are distributed in a straight line), which is not suitable for winding the connector in this application.

[0005] It can be seen that the existing winding device is not suitable for winding the plug-in connector. The wire supply part of the winding device required by the applicant moves in multiple directions under the drive mechanism, and then winds the multiple plug-in connectors one by one. If it is necessary to wind the pins of multiple connectors at one time and facilitate the assembly of the connectors, a clamp is needed that can wind the pins on multiple connectors in sequence at one time, facilitate the installation and removal of the connectors, and guide the winding direction of the plug-in connector and fix the ends of the winding wire. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a molybdenum wire winding plate that can wind the pins of multiple connectors at one time, facilitate the assembly of connectors, guide the winding direction of the connectors, and fix the ends of the wound wires.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: A molybdenum wire winding plate used in a molybdenum wire winding device comprises a winding plate body, on which at least one row of connectors is arranged at intervals, each connector having a plurality of pins, the pins of each row of connectors being arranged one by one, and the spacing between two adjacent connectors in each row of connectors being equal; a row of winding posts corresponding to the pins in the connectors are arranged on both the head and tail sides of each row of connectors; a clamping head for clamping and fixing the end of the molybdenum wire is arranged on both the left and right sides of the winding plate body, corresponding to the initial position of winding and the position of winding completion, the clamping head comprising a clamping head fixed on the winding plate body The fixed block on the upper part and the movable block installed on one side of the fixed block, the movable block and the fixed block are connected together through a pin shaft, a torsion spring is sleeved on the pin shaft, and the two spring legs of the torsion spring are respectively against the movable block and the fixed block; the movable block and the fixed block both include a clamping part and a pushing part located on both sides of the pin shaft, and the clamping part of the movable block and the clamping part of the fixed block have a column at the end; when the pushing part of the movable block is pushed by an external force, the columns at the ends of the movable block and the fixed block are opened to allow the molybdenum wire to pass through; when the external force of the pushing part of the movable block is released, the two columns are closed together and the molybdenum wire is clamped and fixed between the two columns. In this way, 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, and it can adapt to the moving path of the winding part to realize automatic winding. Each connector can be detachably mounted on the winding board, so that each connector can be disassembled after processing is completed, and each connector can be assembled before winding. The winding post arranged near the connector can be used in the winding process. After winding one of the connector pins is completed, when winding the next connector, it is first wound around the winding post and then around the next connector, which is convenient for guiding the winding direction. In addition to the guidance, 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 wound evenly, and the molybdenum wires between two adjacent connectors are not directly wound and do not affect each other. In addition, the set clamping head can clamp the entry end of the molybdenum wire and the end where the winding is completed, so that after the winding is completed and the molybdenum wire is sheared, the end of the molybdenum wire is clamped, which can prevent the end of the molybdenum wire from loosening due to not being fixed. After removing the winding plate and electroplating the winding plate, when removing the molybdenum wire, the movable block of the clamping head can be pushed to open the clamping part and take out the end of the molybdenum wire, thereby realizing the removal of the molybdenum wire. Each connector can be detachably assembled on the winding plate body, so that the connector to be wound can be replaced according to specific needs, and different models and specifications of connectors can be wound, and the versatility is relatively good.

[0008] Furthermore, the winding board body is rectangular, and a plurality of mounting grooves for the connectors to be clamped and fixed are provided on the upper end surface of the winding board body, and the shape of the mounting grooves is adapted to the shape of the connectors and is tightly matched with the connectors. In this way, each connector is assembled on the winding board in a plug-in manner, and when installing, the connector is pressed downward, and when disassembly is completed, the connector can be directly pulled out with force, which makes installation and disassembly more convenient and quick.

[0009] Furthermore, the two clamping heads are located on the left and right sides of one side of the winding plate body, and are symmetrically arranged about the center line of the winding plate body. In this way, the winding heads are arranged at corresponding positions, and the winding heads can be easily pushed during operation.

[0010] Furthermore, the movable blocks of the two clamping heads are both arranged near the outer edge of the side end of the winding plate body, and the pushing portion of the movable block extends out of the side end of the winding plate body. In this way, after the movable block is extended, it is convenient for the operator or the pushing mechanism to apply pressure to the movable block.

[0011] Furthermore, a lifting lug is detachably mounted on both sides of the winding plate body, wherein the lifting lug is L-shaped and the upper end is horizontally bent outward. Thus, after the lifting lug is arranged, it is convenient for the operator to hold the lifting lug and remove the winding plate from the winding device.

[0012] Furthermore, the connectors are provided in two rows, the two adjacent rows of connectors are arranged one-to-one, and a row of winding posts corresponding to the connectors are provided on both sides of the two rows of connectors. In this way, when winding, the two rows of connectors can be wound at one time.

[0013] Furthermore, a mounting hole for fixing the winding plate body on the operating platform of the molybdenum wire winding device is provided on both the left and right sides of the winding plate body, and a positioning bolt is provided in each mounting hole. In this way, the winding plate can be fixed on the operating platform of the winding device by the positioning bolts, thereby fixing the winding plate and avoiding the winding failure caused by the winding plate moving during the winding process and the mismatch between the winding part and the pin of the connector.

[0014] Furthermore, a rubber sleeve is sleeved on each column and can rotate under the action of external force. In this way, after the rubber sleeve is sleeved on the two columns of each clamping head, the rubber sleeve has a certain elasticity and can well press and position the molybdenum wire; at the same time, the rubber sleeve and the column are not tightly matched, and can rotate under the pull of external force, so that when the winding part is winding, it will not affect the winding of the molybdenum wire to the winding column.

[0018] like Figure 1 , Figure 2As shown, a molybdenum wire winding plate used in a molybdenum wire winding device provided in the present embodiment is installed below the winding part, and comprises a winding plate body 1, on which at least one row of connectors 2 are arranged at intervals, each connector 2 has a plurality of pins, the pins of each row of connectors 2 are arranged one by one, and the spacing between two adjacent connectors 2 in each row of connectors 2 is equal; a row of winding posts 3 corresponding to the pins in the connectors 2 are arranged on both sides of the head and tail of each row of connectors 2; a clamping head 4 for clamping and fixing the end of the molybdenum wire is provided on both sides of the left and right sides of the winding plate body 1, corresponding to the initial position of winding and the position of winding completion, the clamping head 4 comprises a fixed block 42 fixed on the winding plate body and a movable block 41 installed on one side of the fixed block 42, the movable block 41 and the fixed block 42 are connected together through a pin shaft 43, and a torsion spring 44 is sleeved on the pin shaft 43, and the two spring legs of the torsion spring 44 are respectively against the movable block 41 and the fixed block 42; the movable block 41 and the fixed block 42 both include a clamping part and a pushing part located on both sides of the pin shaft 43, and the clamping part of the movable block 41 and the clamping part of the fixed block 42 have a column 45 (the column is cylindrical) at the end, and a rubber sleeve 46 that can rotate under the action of external force is sleeved on each column 45; when the pushing part of the movable block 41 is pushed by external force, the columns 45 at the ends of the movable block 41 and the fixed block 42 are opened to allow the molybdenum wire to pass through; when the external force of the pushing part of the movable block 41 is released, the two columns 45 are closed together, and the molybdenum wire is clamped and fixed between the two columns 45. When in use, the molybdenum wire at the end of the winding part is first clamped at the clamping head 4 at the initial position, then wound around the winding post 3 near the clamping head 4, and then wound around the pins of the connector 2 corresponding to the winding post 3 in sequence, until the winding of the pins is completed, and then wound around the winding post 3 near the end of the connector 2. Then, the connector 2 is wound one by one in the order of the winding post 3, the pins of the connector 2, and the winding post 3.

[0019] In this embodiment, the end of the pushing portion of the fixed block of each clamping head is fixed on the winding plate body, a vertical threaded hole is provided at the end of the pushing portion of the fixed block, and a fixed threaded hole corresponding to the vertical threaded hole is provided on the winding plate body. The fixed block is fixedly installed on the winding plate body after threaded cooperation with the vertical threaded hole and the fixed threaded hole by a fixing bolt.

[0020] The connection line between the clamping parts formed by closing the two upright posts 45 in each clamp head 4 in this embodiment overlaps with the connection line of the center points of one row of winding posts 3, so that the winding of the winding posts 3 can be satisfied when the winding part moves horizontally. When the winding board in this embodiment is used, it is placed horizontally, and the side with the clamp head 4 is close to the horizontal moving mechanism, and the pins of the connector 2 are arranged along the width direction of the winding board body, that is, the front and back direction. In order to cooperate with the winding part and realize the winding of the pins at the front and back positions of the docking connector 2, the winding board can move forward and backward driven by a front and back moving mechanism. Of course, in the specific implementation, the connector 2 can be arranged along the length direction of the winding board.

[0021] To accommodate the arrangement of connectors, the winding board body 1 is rectangular, and a plurality of mounting grooves 11 for the connectors 2 to be clamped and fixed are provided on the upper end surface of the winding board body 1. The shape of the mounting grooves 11 is adapted to the shape of the connectors 2 and is tightly fitted with the connectors 2.

[0022] If the installation positions of the clamping heads 4 are one near the edge and the other in the middle, it is not convenient to set the clamping heads 4 when the automatic pushing mechanism is used to push the clamping heads 4. In order to facilitate the automatic pushing of the clamping heads 4 by the pushing mechanism, the two clamping heads 4 are located on the left and right sides of one side of the winding plate body 1, and are symmetrically arranged about the center line of the winding plate body 1. The movable blocks 41 of the two clamping heads 4 are both arranged near the outer edge of the side end of the winding plate body 1, and the pushing portion of the movable block 41 extends out of the side end of the winding plate body 1.

[0023] When the winding is completed, the winding plate needs to be removed. To facilitate holding and placing the winding plate, a lifting lug 5 is detachably installed on both sides of the winding plate body 1. The lifting lug 5 is L-shaped, and the upper end is horizontally bent outward. In this embodiment, the lifting lug is fixed to the side of the winding plate body by a fastener.

[0024] Specifically, the connectors 2 in this embodiment are provided in two rows, and the two adjacent rows of connectors 2 are provided in a one-to-one correspondence, and a row of winding posts 3 corresponding to the connectors 2 is provided on both sides of the two rows of connectors 2 (that is, four rows of winding posts 3 are provided). In a specific implementation, only one row of winding posts 3 may be provided between two adjacent rows of connectors 2.

[0025] During the winding process, if the winding plate is not fixed, it is easy to deviate during the winding process, affecting the winding. To prevent this problem, a mounting hole for fixing the winding plate body on the operating platform of the molybdenum wire winding device is provided on both sides of the winding plate body 1, and a positioning bolt is provided in each mounting hole. The positioning bolt can be directly fixed to the operating platform through a threaded connection, and installation and removal are extremely convenient.

[0026] 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.
