Description

Technical Field

[0001] The invention relates to the technical field of electronic component production equipment, and in particular to a multi-station coil winding machine and a winding method. Background Art

[0002] In the manufacturing process of electronic components, common mode inductors are widely used as a key component. This type of inductor usually requires two layers of copper wire in the positive and negative directions to be wound on it to achieve specific electrical performance requirements. In order to improve production efficiency, multi-head winding machines are often used in the prior art to carry out the winding operation of inductors. However, due to the limitations of their structural design, the currently used multi-head winding machines have a series of problems that need to be solved.

[0003] The existing multi-head winding machine usually includes a loading station, a first winding welding station, a second winding welding station and a unloading station. Each station is provided with a plurality of processing stations for inductor processing parts, and can perform winding operations on multiple inductor coils at the same time. For example, a winding machine and a production method for inductor production disclosed in the Chinese patent CN117352296A can be referred to. Although such a design is intended to improve production efficiency by processing multiple inductor coils at the same time, due to its complex structure, including multiple axes and stations, the overall equipment has a high failure rate. In addition, since there are many inductor coils that need to be processed in each process, the related processing mechanism has a complex structure and is relatively large overall, and the precision of the inductor coil processing must be ensured, resulting in inflexible movement of the mechanism and slow processing rhythm; in addition, this complex multi-axis multi-station integrated structure not only increases the manufacturing cost, but also brings difficulties to maintenance. Once a failure occurs, the entire mechanism often needs to be replaced or repaired, which increases maintenance time and cost. Summary of the invention

[0004] The object of the present invention is to provide a multi-station coil winding machine and a winding method, and to provide a winding machine solution with simpler structure, higher production efficiency, easier maintenance and lower manufacturing cost.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A multi-station coil winding machine comprises a frame assembly, a turntable mechanism mounted on the frame assembly, a loading station, a first winding welding station, a second winding welding station and a unloading station arranged in sequence around the turntable mechanism, the turntable mechanism is provided with at least three processing stations distributed around the turntable mechanism, each processing station is provided with a chuck mechanism; the chuck mechanism comprises a chuck and a driving motor for driving the chuck to rotate;

[0007] The first wire winding and welding station and the second wire winding and welding station have symmetrical structures. The first wire winding and welding station includes a winding device and a welding device, and the winding device and the welding device correspond to the same processing position; the winding device includes a wire supply reel, a multi-axis screw slide and a wire hanging head installed on the multi-axis screw slide; the welding structure includes a multi-axis screw slide and a welding head installed on the multi-axis screw slide.

[0008] Furthermore, the loading station and the unloading station correspond to one processing station, thereby improving the integration of the device and reducing the manufacturing cost of the device.

[0009] Further: there are four processing positions on the turntable mechanism, and the four processing positions are the first processing position, the second processing position, the third processing position and the fourth processing position in sequence. The loading position and the unloading position correspond to the first processing position, the first winding welding position corresponds to the second processing position, the second winding welding position corresponds to the fourth processing position, and the third processing position is close to and faces the edge of the frame. The third position is an empty position, which is used as an observation and debugging position. The winding and welding quality of the first layer of coils on the inductor workpiece can be found in time during operation. If the quality of the finished inductor is inspected after the entire processing operation is completed, it is difficult to check the winding and welding quality of the first layer of coils due to the existence of the second layer of coils; at the same time, if a processing position on the turntable mechanism needs to be debugged, it only needs to be rotated to the third position to conveniently debug it, without disassembling the relevant components of each process next to the turntable mechanism, and it can be adjusted at any time, which greatly improves the debugging efficiency, reduces the debugging risk, and increases the overall processing accuracy of the device.

[0010] Further: the loading station includes a vibration plate assembly and a loading assembly, the vibration plate assembly includes a vibration plate and a vibration conveying guide rail, and a baffle is provided at the end of the vibration conveying guide rail; the loading assembly includes a screw guide rail and a grabbing mechanism installed on the screw guide rail, and the grabbing mechanism includes a cylinder vertically installed on the screw guide rail and a flexible suction nozzle installed on the cylinder; the flexible suction nozzle is located above the vibration conveying guide rail.

[0011] Furthermore: the unloading station includes a material receiving bin, a lifting and rotating cylinder installed between the material receiving bin and the processing station, a mounting block installed on the lifting and rotating cylinder, and a pneumatic suction nozzle installed on the mounting block, and the pneumatic suction nozzle is connected to an external air source through an air pipe.

[0012] Furthermore, the first wire winding welding station also includes a waste suction device, which includes a suction pipe and a suction pipe bracket for installing the suction pipe, one end of the suction pipe is connected to an external negative pressure gas source, and the other end is close to the processing position corresponding to the first wire winding welding station. The suction pipe is used to suck away and discharge the welding waste gas and the waste wire torn off after each inductor winding welding is completed.

[0013] Further: it also includes an abrasive belt feeding device, the abrasive belt conveying device includes a feeding roll and a receiving roll, the feeding roll and the receiving roll are located on both sides of the welding head in the first winding welding station and the welding head in the second winding welding station, and the abrasive belt material between the feeding roll and the receiving roll passes under the welding head. After each welding of the welding head is completed, the welding slag can be removed by rubbing on the abrasive belt to ensure the quality of each electric welding.

[0014] Furthermore, a mounting frame is installed on the frame, and the mounting frame includes a plurality of supporting legs and a plurality of supporting plates installed on the supporting legs, and the turntable mechanism is located in the lower space of the mounting frame, so as to facilitate the installation of each component mechanism.

[0015] Furthermore: the first wire winding welding station also includes a wire crimping device, which includes a rotating bracket installed on the mounting frame and a wire crimping fork installed on the rotating bracket. The rotation normal of the wire crimping fork is horizontal, and the wire crimping fork is coplanar with the rotation axis of the chuck.

[0016] The present invention also provides a winding method applied to the above multi-station coil winding machine.

[0017] The following steps are involved:

[0018] S1: The vibration plate conveys the inductor workpiece to be wound to the vibration conveying guide rail until it reaches the baffle, and the lead screw guide rail drives the flexible suction nozzle to grab the inductor workpiece to be wound from the vibration conveying guide rail to the chuck at the first station, and the chuck clamps the inductor workpiece to be wound;

[0019] S2: The turntable mechanism rotates to send the inductor workpiece to be wound to the second station, and the wire hanging head of the winding device in the first winding welding station sends the inductor wire to the top of the inductor workpiece to be wound; the welding head of the welding device presses down the inductor wire at one end of the inductor workpiece to be wound away from the wire hanging head, and welds the inductor wire at this place to the inductor workpiece; the chuck rotates to wind the inductor wire around the inductor workpiece; the welding head of the welding device presses down again to weld the inductor wire at the other end of the inductor workpiece to the inductor workpiece; at the same time, the first station loads a new inductor workpiece as described in S1.

[0020] S3: The turntable mechanism continues to rotate to send the inductor workpiece to the third station. The third empty station is an empty station. The quality of the inductor workpiece wound by the first winding welding station is monitored at the third station.

[0021] S4: the turntable mechanism continues to rotate to send the inductor workpiece to the fourth station, and the second winding welding station performs the second layer of coil winding on the inductor workpiece as in the steps of S2;

[0022] S5: The turntable mechanism continues to rotate to send the inductor workpiece back to the first station, and the pneumatic suction nozzle of the unloading assembly sucks the wound inductor workpiece. The lifting and rotating cylinder drives the pneumatic suction nozzle to the receiving bin, and the pneumatic suction nozzle unloads the inductor workpiece;

[0023] S6: The above steps S1-S5 are performed in a continuous cycle.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This device improves reliability by simplifying the structure: By adopting a rotary multi-station design to replace the traditional multi-axis multi-station integrated structure, the structure of the processing equipment at each station is simplified, reducing the problem of inflexible movement caused by complex mechanisms, thereby significantly reducing the failure rate of the equipment.

[0026] 2. Improve production efficiency: The design of the rotating workstation makes the transmission of inductor workpieces between each workstation more efficient. Each workstation only processes one inductor workpiece in one unit cycle, which not only speeds up the production cycle, but also ensures higher transmission efficiency. Therefore, the overall processing efficiency of a single inductor coil is higher than that of the winding machine with multi-axis and multi-station integrated structure in the prior art.

[0027] 3. Reduce manufacturing and maintenance costs: Due to the simplified structure of the processing equipment at each station, the corresponding manufacturing cost can be reduced; at the same time, the simplified design is also convenient for maintenance. Even if a fault occurs, it is easier to locate the problem, and it can be partially replaced or repaired. The cost of replacing or repairing parts is lower than that of the winding machine with a multi-axis and multi-station integrated structure in the prior art, thereby reducing maintenance time and cost;

[0028] 4. Enhanced flexibility and debuggability: The introduction of an empty station for observation and debugging allows the quality of wire winding welding to be monitored in real time during the operation of the device, and any station can be easily debugged when necessary, improving the overall processing accuracy.

[0054] In another embodiment, the present invention further provides a winding method applied to the above-mentioned multi-station coil winding machine, comprising the following steps:

[0055] S1: The vibration plate 2.1 conveys the inductor workpiece to be wound to the vibration conveying guide rail 2.2 until it reaches the baffle 2.21, and the lead screw guide rail 2.3 drives the flexible suction nozzle 2.4 to grab the inductor workpiece to be wound from the vibration conveying guide rail 2.2 to the chuck 7.1 at the first station, and the chuck 7.1 clamps the inductor workpiece to be wound;

[0056] S2: The turntable mechanism 7 rotates to send the inductor workpiece to be wound to the second station, and the wire hanging head 3.13 of the winding device 3.1 in the first winding welding station 3 sends the inductor wire to the top of the inductor workpiece to be wound; the welding head 3.22 of the welding device 3.2 presses down the inductor wire at one end of the inductor workpiece to be wound away from the wire hanging head 3.13, and welds the inductor wire at this place to the inductor workpiece; the chuck 7.1 rotates to wind the inductor wire around the inductor workpiece; the welding head 3.22 of the welding device 3.2 presses down again to weld the inductor wire at the other end of the inductor workpiece to the inductor workpiece; at the same time, the first station loads a new inductor workpiece as described in S1.

[0057] S3: the turntable mechanism 7 continues to rotate to send the inductor workpiece to the third station 6. The third empty station is an empty station. The quality of the inductor workpiece wound by the first winding welding station 3 is monitored at the third station 6.

[0058] S4: the turntable mechanism 7 continues to rotate to send the inductor workpiece to the fourth station, and the second winding welding station 4 performs the second layer of coil winding on the inductor workpiece as in the step of S2;

[0059] S5: The turntable mechanism 7 continues to rotate to send the inductor workpiece back to the first station, the pneumatic suction nozzle 5.4 of the unloading assembly sucks the wound inductor workpiece, the lifting and rotating cylinder 5.2 drives the pneumatic suction nozzle 5.4 to the receiving bin 5.1, and the pneumatic suction nozzle 5.4 unloads the inductor workpiece;

[0060] S6: The above steps S1-S5 are performed in a continuous cycle.

[0061] The working principle of the present invention is as follows:

[0062] Before the winding operation begins, the inductor workpiece to be wound is first transported to the loading station 2 by the vibration disk 2.1 and the vibration conveying guide rail 2.2 in the vibration disk 2.1 assembly, and the lead screw guide rail 2.3 in the loading assembly drives the flexible suction nozzle 2.4 to grab the inductor workpiece from the vibration conveying guide rail 2.2 to the chuck 7.1 at the first station, and the chuck 7.1 clamps the inductor workpiece to be wound. Subsequently, the turntable mechanism 7 rotates to send the inductor workpiece to the first winding welding station 3 of the second station, and the wire hanging head 3.13 of the winding device 3.1 sends the inductor wire to the top of the inductor workpiece, and the welding head 3.22 of the welding device 3.2 presses down the inductor wire at one end of the inductor workpiece and welds it to the inductor workpiece, and then the chuck 7.1 rotates to wind the inductor wire around the inductor workpiece, and the welding head 3.22 of the welding device 3.2 presses down again to weld the inductor wire at the other end of the inductor workpiece to the inductor workpiece. At the same time, the operation of loading new inductor workpieces continues at the first workstation.

[0063] Then, the turntable mechanism 7 continues to rotate to send the inductor workpiece to the third station 6, which is an empty station, mainly used to observe and monitor the quality of the inductor workpiece wound by the first winding welding station 3, and ensure that the winding welding quality of each layer of coils meets the standard. If a certain processing position on the turntable mechanism 7 needs to be debugged, the station can be rotated to the third station 6 for debugging, without disassembling other process components beside the turntable mechanism 7, which improves the debugging efficiency and reduces the debugging risk.

[0064] After that, the turntable mechanism 7 continues to rotate to send the inductor workpiece to the second winding welding station 4 at the fourth station, and the station repeats the winding and welding steps of the first winding welding station 3 to complete the winding of the second layer of coils. After the winding is completed, the turntable mechanism 7 continues to rotate to send the inductor workpiece back to the first station. At this time, the pneumatic suction nozzle 5.4 of the unloading assembly sucks the inductor workpiece that has been wound, and drives the pneumatic suction nozzle 5.4 to the receiving bin 5.1 through the lifting and rotating cylinder 5.2 to complete the unloading operation.

[0065] The above steps are operated in a continuous cycle, achieving efficient winding and welding of inductor workpieces. Each workstation only processes one inductor workpiece in a unit cycle, simplifying the equipment structure at each workstation, accelerating the production cycle and reducing the failure rate. The rotating workstation design enables the inductor workpiece to be transferred quickly and efficiently between the workstations, reducing the transfer time and improving production efficiency. At the same time, the simplified equipment structure reduces manufacturing and maintenance costs, making the equipment more reliable and easy to maintain.

[0066] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit of the present invention should be included in the protection scope of the present invention.
