Description

Technical Field

[0001] This application relates to the technical field of inductor production, and particularly to an automatic assembly and wire-wrapping machine for SQ inductors. Background Art

[0002] At present, for SQ (flat wire) inductors, the base is mainly assembled manually and the wire-wrapping process is carried out. A tool such as pliers is relied on to pull out the end of the inductor wire coil and bend it towards the pin, forming an arc structure that can hook the base pin. Finally, the arc structure is clamped to achieve the purpose of wire-wrapping connection. When assembling the base, the inductor wire coil needs to be held horizontally and placed, and then aligned and inserted into the base. During the wire-wrapping process, the end of the wire coil needs to be pulled out by tools such as pliers, and then bent and clamped. Throughout the entire assembly and wire-wrapping process, only one action can be carried out at a time. Moreover, usually, since there are two short wire ends in the wire coil with opposite directions to the corresponding pins on the base, the short wire ends need to be bent in the opposite direction until they can be adjacent to the corresponding pins on the base during assembly, resulting in low production efficiency, high labor intensity, and high labor costs. Also, due to the factor of manual operation, the consistency of the completed products is poor. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0064] The embodiments of the present application disclose an automatic winding machine for SQ inductors.

[0065] Please refer to Figure 1 and Figure 3 One embodiment of an automatic winding machine for SQ inductors provided in the embodiments of the present application includes:

[0066] A wire coil feeding device, a base feeding device, a pre-bending device, a flipping and assembling device, and a winding device; the wire coil feeding device is used to convey the vertically placed wire coil to be assembled; the base feeding device is used to convey the base to be assembled; the pre-bending device is used to reversely bend the short wire ends on the wire coil at a preset angle; the flipping and assembling device is used to flip the bent wire coil into a horizontal position and assemble it on the base on the base feeding device; the winding device is used to wind the wire ends of the assembled wire coil around the corresponding pins of the base where it is located.

[0067] Specifically, the wire coil is conveyed in a vertical state, with the short wire end of the wire coil located at the upper end, which facilitates the pre-bending device to perform pre-bending on the short wire end. The reverse bending process with a preset angle can make the short wire end bend by a preset angle in the direction of increasing the included angle with the adjacent coil part below. The bending trajectory can be formed in the vertical plane where the center line of the short wire end in the length direction is located, that is, a vertical bending. The specific bending angle can be summarized from historical test data, such as 15° - 265°, to ensure that the short wire end after bending can lean against the corresponding pins on the base during wire coil assembly. Taking the bending angle of 180° as an example, the short wire end after bending is in the same direction as the long wire end. When it is further flipped into a horizontal position by the flipping and assembling device and assembled on the base, the short wire end and the long wire end of the wire coil assembled on the base can both lean vertically beside the corresponding pins, thus facilitating the subsequent wire-wrapping device to perform wire-wrapping processing.

[0068] Generally speaking, by conveying the vertical wire coil and then cooperating with the pre-bending device for pre-bending, the short wire end with a certain angular difference from the direction of the base pins can be bent by a preset angle first, so that during assembly, the short wire end can lean against the corresponding pins on the base. Then the bent wire coil is flipped from vertical to horizontal and assembled on the base, and then the wire-wrapping device completes the wire-wrapping process. Through the cooperation of these devices, the automatic wire-wrapping of SQ inductors can be realized, greatly improving production efficiency, reducing labor intensity and labor costs, and also avoiding the instability of manual operation and ensuring product consistency.

[0069] The above is the first embodiment of an SQ inductor automatic assembly and wire-wrapping machine provided by the embodiment of the present application. The following is the second embodiment of an SQ inductor automatic assembly and wire-wrapping machine provided by the embodiment of the present application. For details, please refer to Figures 1 to 13 。

[0070] An SQ inductor automatic assembly and wire-wrapping machine includes: a wire coil feeding device, a base feeding device, a pre-bending device, a flipping and assembling device, and a wire-wrapping device; the wire coil feeding device is used to convey the vertical wire coil to be assembled; the base feeding device is used to convey the base to be assembled; the pre-bending device is used to perform reverse bending on the short wire end of the wire coil by a preset angle; the flipping and assembling device is used to flip the bent wire coil into a horizontal position and assemble it on the base on the base feeding device; the wire-wrapping device is used to wind the wire ends of the assembled wire coil around the corresponding pins of the base where it is located.

[0071] Furthermore, regarding the installation and distribution of each device, the pre-bending device can be installed at the middle position of the wire coil feeding device to facilitate leaving enough feeding space at the front and enough space at the rear for installing other devices. Of course, it is not limited to be installed exactly in the middle. It can be at a position closer to the front part of the middle or at a position closer to the rear part of the middle, and there is no specific limitation.

[0072] The base feeding device is installed in parallel on one side of the wire coil feeding device, and the starting end of the conveyance is located on the side of the pre-bending device close to the end of the wire coil feeding device; the flipping and assembling device is installed at the end position of the wire coil feeding device; the base feeding device and the wire coil feeding device are arranged in parallel, which is more convenient for the wire coil to be transferred from the wire coil feeding device to the base feeding device, and the parallel arrangement can also save a certain amount of installation space. The starting end of the base feeding device is close to the end of the wire coil feeding device, and it is only necessary to have a certain device section between the two feeding devices in parallel, rather than arranging the whole in parallel. The wire coil on the wire coil feeding device can be transferred by the flipping and assembling device through the partially parallel device section, and the wire coil on the wire coil feeding device is transferred to the base feeding device for assembly by the flipping and assembling device. Such a cooperation method will not affect the layout of the front pre-bending device and the rear wire-wrapping device. The wire coil feeding device and the base feeding device can achieve staggered conveyance, leaving a staggered time for transferring the wire coil, so as to facilitate the synchronous transfer and assembly of the wire coil onto the base, and specific changes can be made according to actual needs. Then, the wire-wrapping device is installed at a position close to the end of the base feeding device and on the side of the flipping device close to the end of the base feeding device conveyance.

[0073] Regarding the installation and distribution of each device above, those skilled in the art can make appropriate changes based on the above embodiments, and specific limitations are not made.

[0074] Further, the wire coil feeding device may include a first conveyor 11 and a plurality of wire coil fixing jigs 12; the plurality of wire coil fixing jigs 12 are installed on the first conveyor 11 at intervals along the conveying direction of the first conveyor 11, and a vertical installation cavity 121 for fixing the wire coil is provided at the top of the wire coil fixing jig 12. The wire coil to be assembled can be made in a vertical state through the wire coil fixing jig 12, the vertical installation cavity 121 is adapted to the structure and shape of the wire coil, and an avoidance groove 122 for avoiding the long wire end of the wire coil and communicating with the vertical installation cavity 121 can be provided on one side of the wire coil fixing jig 12, and specific changes can be made according to actual needs.

[0075] Further, the base feeding device may include a second conveyor 13 and a plurality of base fixing jigs 14; the plurality of base fixing jigs 14 are installed on the second conveyor 13 at intervals along the conveying direction of the second conveyor 13, and a fixing station for fixing the base is provided at the top.

[0076] Furthermore, as for the first conveyor 11 and the second conveyor 13, they can be belt conveyors, chain plate conveyors, chain conveyors, etc., and appropriate selections can be made according to actual needs; taking the first conveyor 11 and the second conveyor 13 as chain conveyors as an example; the first conveyor 11 and the second conveyor 13 can both include a conveyor frame 111, a driving gear 112, a driven gear 113, a conveying motor 114 and a conveying chain 115; the driven gear 113 is installed at the first end of the conveyor frame 111; the driving gear 112 is installed at the second end of the conveyor frame 111, and is connected to the driven gear 113 through the conveying chain 115; the conveying motor 114 is installed on one side of the second end of the conveyor frame 111, and is connected to the driven gear 113 for synchronous rotation; a plurality of wire package fixing fixtures 12 are installed at intervals on the conveying chain 115 of the first conveyor 11; a plurality of base fixing fixtures 14 are installed at intervals on the conveying chain 115 of the second conveyor 13. Since the volume of the wire package and the base is not large, a single conveying chain 115 can be used for transportation. The conveying chain 115 is also more convenient for fixing the wire package fixing fixture 12 and the base fixing fixture 14.

[0077] Furthermore, the pre-bending device includes two bending mechanisms 21; the two bending mechanisms 21 are symmetrically installed on both sides of the wire package feeding device along the conveying direction of the wire package feeding device; the bending mechanism 21 includes a first clamping mechanism 211, a horizontal displacement adjustment mechanism and a flipping adjustment mechanism 212; the first clamping mechanism 211 is installed on the flipping adjustment mechanism 212, and the clamping end is used to clamp the short wire end of the wire package; the flipping adjustment mechanism 212 is installed on the horizontal displacement adjustment mechanism and is connected to the first clamping mechanism 211, and is used to drive the first clamping mechanism 211 to flip, so that the short wire end on the wire package is bent in the reverse direction at a preset angle; the horizontal displacement adjustment mechanism is connected to the flipping adjustment mechanism 212, and is used to drive the flipping adjustment mechanism 212 to move in the horizontal direction.

[0078] Specifically, two bending mechanisms 21 are symmetrically arranged, and two short wire ends on the wire package can be bent at the same time. During the bending process, the horizontal displacement of the first clamping mechanism 211 is adjusted by the horizontal displacement adjustment mechanism and the opening and closing of the first clamping mechanism 211 are coordinated, so that the clamping end of the first clamping mechanism 211 can be inserted into the appropriate position of the short wire end of the wire package and the short wire end can be clamped. When the short wire end is clamped, the flip adjustment mechanism 212 can be controlled to control the first clamping mechanism 211 to first bend the short wire end with a certain angle between the vertical plane where the pins corresponding to the base are located to a preset angle, so that during subsequent assembly, the short wire end can be adjacent to the corresponding pins of the base. The overall rapid bending process of the short wire end of the wire package is achieved, further improving the processing efficiency. In terms of cooperation with the wire package feeding device, in order to enable the wire package on the wire package feeding device to accurately reach the position between the two bending mechanisms 21, the conveying interval of the wire package feeding device can be set, that is, when the wire package travels a preset distance and reaches the position between the bending mechanisms 21, it stays for a preset time, so that the bending mechanism 21 can bend the wire package. The bending mechanism 21 can be provided with a positioning sensor at the clamping end position of the first clamping mechanism 211, such as a radio frequency identification sensor, to achieve alignment clamping by identifying the radio frequency tag on the wire package fixing fixture 12, etc. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0079] Further, in terms of the structural composition of the horizontal adjustment mechanism, the horizontal adjustment mechanism may include a first horizontal displacement adjustment mechanism 214 and a second horizontal displacement adjustment mechanism 213; the flip adjustment mechanism 212 is installed on the second horizontal displacement adjustment mechanism 213; the second horizontal displacement adjustment mechanism 213 is installed on the first horizontal displacement adjustment mechanism 214 and connected to the flip adjustment mechanism 212, and is used to drive the flip adjustment mechanism 212 to move in a first direction parallel to the wire package conveying direction; the first horizontal displacement adjustment mechanism 214 is connected to the second horizontal displacement adjustment mechanism 213, and is used to drive the second horizontal displacement adjustment mechanism 213 to move in a second direction perpendicular to the first direction. The horizontal adjustment mechanism is composed of two mutually perpendicular direction adjustment mechanisms, so that the first clamping mechanism 211 can achieve more flexible displacement adjustment.

[0080] Further, the first horizontal displacement adjusting mechanism 214 may include a first fixed seat 2141, a first slider 2143, and a first driver 2142; the first slider 2143 is slidably mounted on the top of the first fixed seat 2141; the first driver 2142 is mounted on the top of the first fixed seat 2141, and its driving end is connected to the first slider 2143 for driving the first slider 2143 to slide; the second horizontal displacement adjusting mechanism 213 is mounted on the top of the first slider 2143. Specifically, during control, the first driver 2142 drives the first slider 2143 to slide on the first fixed seat 2141 to achieve displacement adjustment in the first direction.

[0081] Further, the second horizontal displacement adjusting mechanism 213 may include a second slider 2131 and a second driver 2132; the second slider 2131 is slidably mounted on the top of the second driver 2132; the second driver 2132 is mounted on the top of the first slider 2143, and its driving end is connected to the second slider 2131 for driving the second slider 2131 to slide. Directly mounting the second slider 2131 on the top of the first slider 2143 through the second driver 2132 means that the second slider 2131 can be slidably mounted on the top of the second driver 2132, or slide in cooperation with the first slider 2143 through a guide rail portion (not shown in the figure) at the bottom and form an avoidance cavity for mounting the second driver 2132 with the first slider 2143, so as to save installation space and make the overall structure more compact. Of course, whether it is the first horizontal displacement adjusting mechanism 214 or the second horizontal displacement adjusting mechanism 213, the present application is not limited to the given installation methods, and can also be other combinations or installation structures, which can be appropriately changed according to the types of the first driver 2142 and the second driver 2132 used.

[0082] Further, both the first driver 2142 and the second driver 2132 may specifically be first linear cylinders. Of course, they can also be electric push rod devices, lead screw slide table devices, etc., without specific limitation.

[0083] Further, in terms of the structural composition of the flipping adjusting mechanism 212, the flipping adjusting mechanism 212 may include a fixed frame 2121, a rack 2123, a cylindrical gear 2124, and a third driver 2122; the fixed frame 2121 is mounted on the top of the second slider 2131 and forms an installation cavity with the top of the second slider 2131; the rack 2123 is slidably mounted on one side wall in the installation cavity along the second direction; the third driver 2122 is mounted on the top of the second slider 2131 and is connected to the rack 2123 for driving the rack 2123 to slide; the cylindrical gear 2124 is engaged with the rack 2123 and is synchronously rotationally connected to the first clamping mechanism 211.

[0084] Specifically, the structure of the fixing bracket 2121 can be formed by assembling three or more plates as shown in the figure, forming a through installation cavity in the middle to facilitate the installation and use of the third driver 2122, the rack 2123, the gear, etc. The third driver 2122 can also be a linear cylinder, an electric push rod device, etc., without specific limitation. The working process of driving the first clamping mechanism 211 to flip is as follows. When the horizontal displacement adjustment mechanism adjusts the first clamping mechanism 211 in place and the first clamping mechanism 211 clamps the short wire head on the wire coil, the third driver 2122 can drive the straight rack 2123 to slide along the second direction, and then the cylindrical gear 2124 meshing with it rotates, thereby driving the first clamping mechanism 211 to flip. By using the cooperation of the rack 2123 and the cylindrical gear 2124, the linear motion can be converted into rotational motion, and thus there is no need to directly connect to the first clamping mechanism 211 to drive the first clamping mechanism 211 to rotate. Such a transmission method can also reduce a certain installation space and make the overall structure more compact. Of course, the present application is not limited to the above-described embodiments. It is also possible to achieve direct connection drive through a drive such as a rotary motor, or to achieve rotational control of the first clamping mechanism 211 through other transmission mechanisms, such as a belt pulley mechanism, a gear set, etc. In addition, in order to limit the movement of the rack 2123 in this embodiment, a limit stop 2125 can also be provided on the side wall of the installation cavity where the rack 2123 is installed to limit the movement of the rack 2123, without specific limitation.

[0085] Further, the first clamping mechanism 211 can include a bracket 2111, a fourth driver 2112, a connecting rod 2113, a wire head chuck 2115, and a compression spring 2114; above the rack 2123 in the installation cavity, a connecting sleeve 2126 is pivotally connected along the first direction; the cylindrical gear 2124 is fixedly sleeved on the connecting sleeve 2126; the wire head chuck 2115 is installed at one end of the connecting sleeve 2126 facing the wire coil feeding device; the connecting rod 2113 is telescopically inserted into the connecting sleeve 2126 along the first direction and is rotationally matched with the connecting sleeve 2126 synchronously; a limiting portion 2116 is provided at one end of the connecting rod 2113 extending out of the connecting sleeve 2126 along the opposite direction of the first direction, and the other end is connected to the wire head chuck 2115; the compression spring 2114 is sleeved on the rod section of the connecting rod 2113 extending out of the connecting sleeve 2126 along the opposite direction of the first direction, and one end is in contact and abuts against the limiting portion 2116, and the other end is in contact and abuts against the connecting sleeve 2126; the fourth driver 2112 is fixed on the outer side wall of the fixing bracket 2121 facing away from the wire coil feeding device through a driver mounting bracket and is used for actively pushing the connecting rod 2113; when the fourth driver 2112 does not push the connecting rod 2113, the wire head chuck 2115 is in a clamped state.

[0086] Specifically, in order to achieve the clamping control of the first clamping mechanism 211 and not affect the flipping control of the first clamping mechanism 211, the fourth driver 2112 is detachably installed with the clamping part. For this purpose, a clamping design is adopted in which the link 2113 can drive the wire head chuck 2115 to open and close by telescoping. This enables the clamping part to be separated independently, and the initial closing power is provided by the compression spring 2114. In the initial state, the reset elastic force provided by the compression spring 2114 drives and pulls the link 2113, causing the wire head chuck 2115 to be in a closed state. When clamping is required, the fourth driver 2112 can be controlled to push the link 2113, causing the wire head chuck 2115 to loosen, so that the short wire head of the wire coil can be clamped and fixed. In order to achieve better synchronous rotation cooperation between the cylindrical gear 2124 and the link 2113, in this embodiment, a connecting sleeve 2126 is pivotally connected inside the fixed frame 2121, and the link 2113 can be movably inserted through the connecting sleeve 2126 to achieve telescopic movement in the axial direction, but fixed cooperation in the radial direction. Correspondingly, corresponding key grooves can be provided in the connecting sleeve 2126, so that the link 2113 can only move in the axial direction and cannot rotate with the connecting sleeve 2126. Further, it can be ensured that the fourth driver 2112 can drive the link 2113 to drive the opening and closing of the wire head chuck 2115, and it will not affect the overall rotation of the link 2113 and the wire head chuck 2115.

[0087] Further, the wire head chuck 2115 may include a lower chuck base 2115a and a movable chuck block 2115b; one end of the lower chuck base 2115a is fixedly connected to the connecting sleeve 2126, and the other end is provided with a lower clip portion 2115d; the movable chuck block 2115b is hinged to the lower chuck base 2115a, and one end is connected to the link 2113 through a connecting arm 2115f, and the other end is provided with an upper clip portion 2115c that clamps and cooperates with the lower clip portion 2115d; one end of the connecting arm 2115f is hinged to the movable chuck block 2115b, and the other end is hinged to the link 2113. With such a structural design, the telescopic movement of the link 2113 can be realized to drive the opening and closing of the wire head chuck 2115. When the link 2113 pulls the connecting arm 2115f under the action of the compression spring 2114, the connecting arm 2115f forms an upward pulling force on the movable chuck block 2115b, and further causes the upper clip portion 2115c of the movable chuck block 2115b to press the lower clip portion 2115d toward the lower clip portion 2115d, thereby achieving closing. When the fourth driver 2112 pushes the link 2113, it drives the connecting arm 2115f to pull the movable chuck block 2115b downward, causing the upper clip portion 2115c of the movable chuck block 2115b to move away from the lower clip portion 2115d, realizing opening. The upper clip portion 2115c and the lower clip portion 2115d can be designed in a thin sheet structure, which is convenient for inserting the short wire head into an appropriate position, and no specific limitation is made.

[0088] Further, the fourth driver 2112 may specifically be a second linear cylinder. Of course, it may also be an electric push rod device or the like, and there is no specific limitation.

[0089] Further, when bending the short wire end of the wire coil, a force will be generated on the wire coil. If the wire coil is not fixed properly, there is a risk that the bending may not be in place or the wire coil may be disengaged from the wire coil fixing fixture 12. Therefore, in this embodiment, the pre-bending device may further include a first pressing mechanism 22; the first pressing mechanism 22 is installed between the two bending mechanisms 21 and is used to press the wire coil vertically downward to improve the stability of bending.

[0090] Further, the first pressing mechanism 22 may include a first pressing support frame 221, a fifth driver 222, and a first pressing fixture 223; the first pressing support frame 221 is provided with an avoidance cavity for avoiding the wire coil feeding device; the fifth driver 222 is installed upside down on the top of the first pressing support frame 221, and the driving end vertically extends downward into the avoidance cavity; the first pressing fixture 223 is installed on the driving end of the fifth driver 222.

[0091] Specifically, the structure of the first pressing support frame 221 can be as shown in the figure, which can support and fix the fifth driver 222 without affecting the normal feeding of the wire coil feeding device, and the structure is not limited. When the wire coil is conveyed to directly below the first pressing fixture 223, the fifth driver 222 can be controlled to drive the first pressing fixture 223 to press the wire coil downward. The structure of the first pressing fixture 223 can be adaptively designed according to the specific structure of the wire coil to ensure that the wire coil can be pressed without damaging the wire coil and without affecting the clamping and flipping of the first clamping mechanism 211, and there is no specific limitation. Referring to the foregoing, the fifth driver 222 in this embodiment may also be a linear cylinder or an electric push rod device or the like, and there is no specific limitation.

[0092] Further, since the short wire end after bending may not be bent in place, in this embodiment, the pre-bending device further includes a correction mechanism 23; the correction mechanism 23 is installed on one side of the bending mechanism 21 close to the conveying end of the wire coil feeding device and is used to press and correct the short wire end of the bent wire coil. The design of the correction mechanism 23 and the first pressing mechanism 22 may be similar. The correction mechanism 23 may also drive a correction fixture 231 through a corresponding driver to press and correct the short wire end of the wire coil so that the short wire end can be at an accurate bending angle. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0093] Furthermore, the flipping and assembling device includes a flipping and assembling support frame 31, a transfer wire package flipping mechanism 36, a first assembling displacement adjusting mechanism 32, a second assembling displacement adjusting mechanism 33, a second clamping mechanism 34, and a third clamping mechanism 35; the second clamping mechanism 34 and the third clamping mechanism 35 are installed at intervals on the second assembling displacement adjusting mechanism 33, and are respectively used for clamping the wire package of the wire package feeding device and the transfer wire package on the transfer wire package flipping mechanism 36; the second assembling displacement adjusting mechanism 33 is installed on the first assembling displacement adjusting mechanism 32, and is used to drive the second clamping mechanism 34 and the third clamping mechanism 35 to move up and down in the vertical direction; the first assembling displacement adjusting mechanism 32 is installed on the flipping and assembling support frame 31, and is used to drive the second assembling displacement adjusting mechanism 33 to move horizontally; the transfer wire package flipping mechanism 36 is installed on the same side of the second clamping mechanism 34 and the third clamping mechanism 35 relative to the flipping and assembling support frame 31, and is used to flip the vertical wire package clamped by the second clamping mechanism 34 into a horizontal transfer wire package.

[0094] Specifically, by setting the first assembling displacement adjusting mechanism 32, the second clamping mechanism 34 and the third clamping mechanism 35 can reciprocate between the wire package feeding device and the base feeding device, so as to transfer the wire package on the wire package feeding device to the base on the base feeding device for assembly. A transfer wire package flipping mechanism 36 is also provided between the wire package feeding device and the base feeding device, which is used to flip the vertical wire package transported by the second clamping mechanism 34 so that the wire package becomes horizontal, and then transport it to the base on the base feeding device for assembly on the corresponding base through the third clamping mechanism 35. In this embodiment, the purpose of using the double clamping mechanism is to simultaneously clamp the wire package on the wire package feeding device and the wire package that has been flipped to the horizontal state on the transfer wire package flipping mechanism 36. Then, when the second clamping mechanism 34 moves to the transfer wire package flipping mechanism 36, the third clamping mechanism 35 can synchronously move above the corresponding base on the base feeding device, realizing the synchronous progress of transfer and assembly, effectively realizing the synchronous cooperation between the wire package feeding device and the base feeding device, and improving production efficiency.

[0095] The working process can be as follows. The first assembly displacement adjustment mechanism 32 drives the second assembly displacement adjustment to move until the second clamping mechanism 34 and the third clamping mechanism 35 are respectively located above the wire package feeding device and above the transfer wire package flipping mechanism 36. At this time, the second assembly displacement adjustment mechanism 33 is controlled again, so that the second clamping mechanism 34 and the second clamping mechanism 34 descend to a specified height. During the descent, the second clamping mechanism 34 and the third clamping mechanism 35 are controlled to open. After descending in place, the second clamping mechanism 34 can be controlled to clamp the wire package on the wire package feeding device, and the third clamping mechanism 35 can be controlled to clamp the flipped wire package on the transfer wire package flipping mechanism 36. Then, the second assembly displacement adjustment mechanism 33 is controlled to reset and the first assembly displacement adjustment mechanism 32 is controlled to move in the direction of the base feeding device. This process can enable operations such as resetting of the transfer wire package flipping mechanism 36 to wait for the flipping process of the next wire package. When the first assembly displacement adjustment mechanism 32 is controlled until the second clamping mechanism 34 and the third clamping mechanism 35 are respectively located above the transfer wire package flipping mechanism 36 and the base feeding device, then the second assembly displacement adjustment mechanism 33 is controlled until the second clamping mechanism 34 and the third clamping mechanism 35 descend to a certain height, and then the second clamping mechanism 34 and the third clamping mechanism 35 are respectively opened, so that the wire package clamped by the second clamping mechanism 34 is placed on the transfer wire package flipping mechanism 36, and the wire package clamped by the third clamping mechanism 35 is placed on the corresponding base on the base feeding device to complete the assembly. While the second clamping mechanism 34 and the third clamping mechanism 35 return, the transfer wire package flipping mechanism 36 can be controlled to flip the vertical wire package to form a horizontal transfer wire package for the next clamping by the third clamping mechanism 35.

[0096] Further, the flipping and assembling support frame 31 can specifically be a gantry structure. Of course, it can also be other structures that can play a stable supporting and fixing role and do not affect the normal operation of the wire package feeding device and the base feeding device.

[0097] Further, the first assembly displacement adjustment mechanism 32 can specifically be a rodless cylinder mechanism; the second assembly displacement adjustment mechanism 33 is installed on the cylinder slider of the rodless cylinder mechanism. Specifically, in order to ensure the load-bearing capacity, the first assembly displacement adjustment mechanism 32 can be a mechanical rodless cylinder mechanism or a lead screw slide device, etc., without specific limitation, and those skilled in the art can make appropriate transformations according to the actual situation. Of course, in order to reduce the load of the second assembly displacement adjustment mechanism 33 on the first assembly displacement adjustment mechanism 32, the second assembly displacement adjustment mechanism 33 can also be slidably matched with the flipping and assembling support frame 31, without specific limitation.

[0098] Further, the second assembly displacement adjustment mechanism 33 may include a second fixed seat 331, a third slider 333, and a sixth driver 332; the second fixed seat 331 is vertically arranged and connected to the cylinder slider; the third slider 333 is slidably mounted on the second fixed seat 331 in the vertical direction; the sixth driver 332 is mounted on the top of the second fixed seat 331, and the driving end is connected to the third slider 333 for driving the third slider 333 to move up and down; the second clamping mechanism 34 and the third clamping mechanism 35 are mounted on the third slider 333. Specifically, during control, the sixth driver 332 controls the third slider 333 to slide up and down in the second fixed seat 331 in the vertical direction to achieve the lifting control of the second clamping mechanism 34 and the third clamping mechanism 35. In this embodiment, the sixth driver 332 may be a third linear cylinder, and of course, it may also be an electric push rod device, etc., without specific limitation. Of course, the second assembly displacement adjustment mechanism 33 may also adopt a lead screw slider device or a mechanical rodless cylinder device, etc.

[0099] Further, the second clamping mechanism 34 may include a first clamping cylinder and a first wire package chuck; the driving end of the first clamping cylinder is connected to the first wire package chuck for driving the first wire package chuck to open and close. The opening and closing of the first wire package chuck are controlled by the first clamping cylinder. Of course, it may also be other types of jaw mechanisms, without specific limitation.

[0100] Similarly, the third clamping mechanism 35 may also include a second clamping cylinder and a second wire package chuck; the driving end of the second clamping cylinder is connected to the second wire package chuck for driving the second wire package chuck to open and close.

[0101] Further, the transfer wire package flipping mechanism 36 includes a third fixed seat 361, a seventh driver 362, and a flipping fixture 363; the seventh driver 362 is mounted on the third fixed seat 361, and the driving end is connected to the flipping fixture 363 for driving the flipping fixture 363 to flip; a semi-open flipping station is provided on the flipping fixture 363.

[0102] Specifically, the flipping fixture 363 can be of an L-shaped structure, with a horizontal installation station provided on the vertical side and a vertical installation station provided on the horizontal side; in the initial state, it can be in a positive "L" shape, that is, the vertical installation station faces upward. At this time, when the second clamping mechanism 34 clamps the wire coil and leaves after placing it on the flipping fixture 363, the flipping fixture 363 can be controlled by the seventh driver 362 to rotate counterclockwise by 90°, so that the horizontal installation station of the flipping fixture 363 faces upward, and at this time the wire coil becomes in a horizontal state. When designing the flipping fixture 363, the horizontal installation station in the flipping fixture 363 can be made into a concave cavity, and the thickness of the flipping fixture 363 can be less than the distance between the two short wire ends of the wire coil, that is, to ensure that the flipping fixture 363 will not interfere with the wire ends of the wire coil during the flipping process. Specifically, appropriate adjustments can be made according to the actual situation without limitation.

[0103] Furthermore, since the flipped wire coil may have a certain displacement deviation, for this reason, the transfer wire coil flipping mechanism 36 can further include an eighth driver 37; the eighth driver 37 is installed at a position below the seventh driver 362 on the third fixed seat 361, and the driving end is connected to a baffle; the baffle is used to adjust the position of the wire coil when the wire coil is in a horizontal state. The baffle is arranged opposite to the position of the flipping fixture 363. When the flipping fixture 363 flips, the baffle can move away from the flipping fixture 363 under the control of the eighth driver 37 to avoid interfering with the flipping fixture 363. After the flipping fixture 363 finishes flipping, it can then move in the direction of the flipping fixture 363 under the control of the eighth driver 37 and slightly clamp the horizontal wire coil to correct the position of the wire coil, so that the wire coil is in an accurate position, improving the subsequent assembly accuracy and ensuring the stability of the assembly. Taking the parallelism of the conveying directions of the wire coil feeding device and the base feeding device as an example, the plane formed by the flipping trajectory of the flipping fixture 363 is parallel to the wire coil feeding device and the conveying direction of the wire coil feeding device or the base feeding device, and the adjusting direction of the first assembly displacement adjusting mechanism 32 is perpendicular to the conveying direction of the wire coil feeding device or the base feeding device.

[0104] Furthermore, in the above embodiment, the seventh driver 362 can specifically be a rotary cylinder or a rotary motor, etc.; similarly, the eighth driver 37 can specifically be a fourth linear cylinder or an electric push rod device, etc.

[0105] Further, the foot-binding device includes a foot-binding mechanism group, two foot-binding displacement adjustment mechanisms 42, and second pressing mechanisms 45 corresponding to the foot-binding mechanism group one by one; the two foot-binding displacement adjustment mechanisms 42 are symmetrically installed on both sides of the base feeding device along the conveying direction of the base feeding device; the foot-binding mechanism group is composed of two foot-binding mechanisms; the two foot-binding mechanisms 41 are respectively installed on the foot-binding displacement adjustment mechanisms 42; the foot-binding displacement adjustment mechanism 42 is used to drive the foot-binding mechanism 41 to move in a direction perpendicular to the conveying direction of the base feeding device; the second pressing mechanism 45 is installed between the two foot-binding displacement adjustment mechanisms 42 and is used to vertically press down on the wire coil assembled on the base.

[0106] Specifically, two foot-binding mechanisms are symmetrically arranged to form a foot-binding mechanism group to realize the foot-binding treatment of the wire coil assembled on the base. And the provided foot-binding position adjustment mechanism is used to respectively adjust the movement of the foot-binding mechanism 41 in the direction of approaching or departing from the base feeding device, so as to conveniently adjust the appropriate position and perform the foot-binding treatment. Moreover, a second pressing mechanism 45 is also provided to press the wire coil assembled on the base to ensure that the wire coil will not shift during the foot-binding treatment process, and to ensure the stability and effect of foot-binding.

[0107] Further, the foot-binding mechanism group is specifically two groups; the foot-binding mechanisms 41 of each foot-binding mechanism group are sequentially arranged at intervals along the conveying direction of the base feeding device. When the foot-binding mechanism 41 is arranged in two groups, the two groups can respectively perform foot-binding treatment on different pins. That is, when one group of foot-binding mechanisms 41 performs foot-binding treatment on the first two pins of a base, at the same time, the other group is also performing foot-binding treatment on the other two pins of the next base, thereby further improving the efficiency of foot-binding. Of course, in this application, the foot-binding mechanism group can also be more than two groups, such as four groups, and those skilled in the art can make appropriate selections and applications based on this, and no specific restrictions are made.

[0108] Further, the foot-binding displacement adjustment mechanism 42 includes a ninth driver 422, a fourth fixed seat 421, and a sliding plate 423; the sliding plate 423 is installed on the fixed seat 421 and along the direction perpendicular to the conveying direction of the base feeding device; the foot-binding mechanism 41 is installed on the top of the sliding plate 423; the ninth driver 422 is installed on the fixed plate, and the driving end is connected to the sliding plate 423 and is used to drive the sliding plate 423 to move. Specifically, the ninth driver 422 can be a linear cylinder, or a servo motor and an electric push rod device, etc. If it is a linear cylinder, it can be directly connected to the sliding plate 423. If it is a servo motor, it can be connected to the sliding plate 423 through a lead screw transmission mechanism, and no specific restrictions are made.

[0109] Furthermore, the foot-binding mechanism 41 may include a tenth driver 411 and a foot-binding jig 412; the tenth driver 411 is mounted on the top of the slide plate 423, and the driving end is connected to the foot-binding jig 412, and is used to drive the foot-binding jig 412 to rotate. The winding method may be a tossing winding, and the foot-binding jig 412 is used to toss the thread end around the base pin to bend, thereby achieving foot binding. The tenth driver 411 may be a servo motor that can be rotated forward and reverse, etc., and there is no specific limitation.

[0110] Further, with regard to the structure of the foot-binding jig 412, the foot-binding jig 412 may include a jig body that is synchronously connected to the driving end of the tenth driver 411; a positioning portion for the base pin to be inserted movably is provided at the center of one end of the jig body facing the base feeding device; a foot-binding column (not shown) is also provided at the center of one end of the jig body facing the base feeding device; a foot-binding gap is formed between the foot-binding column and the pin for the thread end of the thread package to pass movably. The jig body may be a cylindrical structure, and a positioning portion may be provided at the center of the end facing the base for locating the pin position, so that the rotation axis of the foot-binding jig 412 coincides with the corresponding pin, so that when rotating, the thread end of the thread package can be stably moved to the pin wound around the base through the rotation of the foot-binding column, thereby achieving fast and accurate winding processing.

[0111] Furthermore, the positioning portion can specifically be a positioning guide hole for the pins of the base to be movably inserted, and the positioning depth can be adjusted according to actual needs so that when the foot binding fixture 412 is positioned and coordinated with the base pins, it will not interfere with the winding of the thread ends of the thread package, and there is no specific limitation.

[0112] Furthermore, the second clamping mechanism 45 may include a second clamping support frame 451, an eleventh driver 452 and a second clamping fixture 453; the eleventh driver 452 is inverted on the top of the second clamping support frame 451, and the driving end extends vertically downward into itself to form a second avoidance cavity for avoiding the base feeding device; the second clamping fixture 453 is installed on the driving end of the eleventh driver 452. The design of the second clamping support frame 451 can be as shown in the figure, which can play a supporting role and will not interfere with the normal operation of the base feeding device, without specific restrictions. When there are multiple second clamping mechanisms 45, a second clamping support frame 451 can be shared, that is, the eleventh driver 452 can be installed on the same second clamping support frame 451. The eleventh driver 452 can be a linear cylinder or an electric push rod device, etc., without specific restrictions.

[0113] Further, the short or long wire ends after the wire winding process may not be wound properly. Therefore, it may further include a plurality of clamping mechanisms 44 corresponding to the wire winding mechanism 41 one by one; each clamping mechanism 44 is respectively installed on the wire winding displacement adjustment mechanism 42, and along the conveying direction of the base feeding device, they are sequentially arranged on one side of the wire winding mechanism 41 close to the conveying end of the base feeding device.

In this application, the second pressing fixture 453 of the second pressing mechanism 45 not only corresponds to the wire winding mechanism 41, but also can correspond to the clamping mechanism 44. When the eleventh driver 452 drives the second pressing fixture 453 to press down, it can not only press the wire package and the base that need wire winding treatment, but also press the wire package and the base that need clamping treatment at the same time.

Specifically, the twelfth driver 43 may be a linear cylinder or an electric push rod device, etc., and is not specifically limited. Setting the twelfth driver 43 to drive the wire winding mechanism 41 can facilitate the adjustment and alignment of the wire winding mechanism 41.
