[0030] Compared with the high pin hardness and the difficulty of bending and interlacing of the coil of the inductance product, the two pins 810 of the coil 800 of the wireless charger are relatively soft, and the two pins 810 of the coil 800 are prone to twisting and interlacing, and the working condition is complex. There is no automatic feeding equipment capable of processing such coil 800 in the prior art, and the production line of the wireless charger can only be fed by manual clamping.

[0031] Referring to Figures 1 to 4 , the wireless charging coil automatic feeding equipment according to the embodiment of the present application comprises a rack 100, a material arranging mechanism, a material transferring mechanism 400 and a clamping mechanism 500. The rack 100 is provided with a material arranging station, a feeding station and a material storage station for storing the coil 800. The feeding station is provided with a clamp 200 for clamping the coil 800. The material arranging mechanism is arranged at the material arranging station. The material arranging mechanism comprises a fixing assembly 310 for fixing the coil 800 and a straightening assembly 320. The straightening assembly 320 is located on one side of the fixing assembly 310. A first driving device 330 for driving the straightening assembly 320 to move is arranged between the straightening assembly 320 and the rack 100. The straightening assembly 320 can separate and clamp the two pins 810 of the coil 800 on the fixing assembly 310. The first driving device 330 can drive the straightening assembly 320 to move away from the fixing assembly 310 to straighten the two pins 810 of the coil 800. The material transferring mechanism 400 is arranged on the rack 100. The material transferring mechanism 400 is used to transfer the coil 800 on the material storage station to the fixing assembly 310 for fixing. The clamping mechanism 500 is used to transfer the coil 800 on the fixing assembly 310 to the clamp 200 for clamping. The clamping mechanism 500 is provided with a first gripping assembly 520 and a second gripping assembly 530. When the clamping mechanism 500 grips the coil 800 on the material arranging mechanism, the first gripping assembly 520 can move above the fixing assembly 310 and grip the coil 800, and at the same time, the second gripping assembly 530 moves between the fixing assembly 310 and the straightening assembly 320 and grips the two pins 810 of the coil 800.

[0032] As shown in Figure 4 , the clamp 200 is usually provided with a clamping column 210 and two clamping grooves 220. The two clamping grooves 220 are located on one side of the clamping column 210. When the coil 800 is clamped on the clamp 200, the main body of the coil 800 is sleeved on the clamping column 210, and the pins of the coil 800 pass through the corresponding clamping grooves 220 and are clamped by the two side walls of the corresponding clamping grooves 220.

[0033] Referring to Figures 1 to 4In the clamping and feeding process, the material transfer mechanism 400 can transfer the coil 800 at the storage station to the fixing assembly 310 for fixing, the straightening assembly 320 is separated from the lead 810 of the coil 800 and clamps the two leads 810 of the coil 800, then the first driving device 330 drives the straightening assembly 320 to move away from the fixing assembly 310 to straighten and separate the two leads 810 of the coil 800, the clamping mechanism 500 can move the first gripping assembly 520 above the fixing assembly 310 and grip the coil 800, and move the second gripping assembly 530 between the fixing assembly 310 and the straightening assembly 320 and grip the two leads 810 of the coil 800, then the clamping mechanism 500 transfers the coil 800 to the clamp 200 at the feeding station, in this process, the two leads 810 of the coil 800 can always be kept separated and straightened to prevent the two leads 810 of the coil 800 from being bent and intertwined with each other, then the clamping mechanism 500 places the coil 800 on the clamp 200 from top to bottom, that is, the main body of the coil 800 is successfully clamped on the clamping column of the clamp 200, and the two leads 810 of the coil 800 are clamped into the clamping groove of the clamp 200, through the above arrangement, the wireless charging coil automatic feeding equipment provided by the present application can replace the staff to clamp the coil 800 on the clamp 200, realize automatic clamping and feeding of the coil 800, and improve the production efficiency.

[0034] With reference to Figure 4 In some embodiments, an upper feeding conveying mechanism can be arranged at the feeding station, and the clamp 200 clamping the coil 800 is conveyed to the next process by the upper feeding conveying mechanism. Of course, it should be noted that in the specific implementation process, the clamp 200 can also be conveyed to the next process by the clamping mechanism 500, or the clamp 200 can be taken by the production equipment of the next process, for example, the production equipment of the next process is used for soldering the lead 810 of the coil 800, and the soldering mechanical hand is arranged in the production equipment, so that the clamp 200 can be taken from the feeding station by the soldering mechanical hand.

[0035] With reference to Figure 2 and Figure 6It is conceivable that, in some embodiments, the straightening assembly 320 comprises a sliding seat 321, a second driving device 322, a separation rod 323 and two clamping jaws 324, the sliding seat 321 is slidably installed on the rack 100, the first driving device 330 is capable of driving the sliding seat 321 to move close to or away from the fixing assembly 310, the second driving device 322 is installed on the sliding seat 321, the two clamping jaws 324 are in transmission connection with the second driving device 322, the separation rod 323 is vertically installed on the sliding seat 321 or the second driving device 322, the separation rod 323 is located between the two clamping jaws 324, the separation rod 323 is capable of being inserted between the two pins 810 of the coil 800 on the fixing assembly 310, and the second driving device 322 is capable of driving the two clamping jaws 324 to move close to or away from the separation rod 323. During the process of straightening and separating the two pins 810 of the coil 800, the first driving device 330 first drives the sliding seat 321 to move close to the fixing assembly 310, and then the material transferring mechanism 400 clamps the coil 800 on the fixing assembly 310 from top to bottom, during which the pin leading-out position of the coil 800 faces the straightening assembly 320, near the pin leading-out position of the coil 800, the two pins 810 of the coil 800 are usually separated from each other, so that the separation rod 323 can be easily inserted between the two pins 810 from the pin leading-out position of the coil 800, thereby separating the two pins 810, then the second driving device 322 drives the two clamping jaws 324 to move close to the separation rod 323, so that the straightening assembly 320 clamps the two pins 810 of the coil 800, and finally the first driving device 330 drives the sliding seat 321 to move away from the fixing assembly 310, thereby separating and straightening the two pins 810 of the coil 800. With the above arrangement, the material straightening mechanism can successfully separate and straighten the two pins 810 of the coil 800, preventing the two pins 810 of the coil 800 from being intertwined, and in addition, the entire straightening assembly 320 only needs one second driving device 322 to meet the working requirements, and the structure is more compact.

[0036] With reference to Figure 2 And Figure 6 It is conceivable that, in some embodiments, the upper end of the separation rod 323 is provided with two separation inclined surfaces 3231, the two separation inclined surfaces 3231 correspondingly face the two clamping jaws 324, and the distance between the two separation inclined surfaces 3231 gradually increases in the direction from top to bottom. Through the arrangement of the two separation inclined surfaces 3231, the separation rod 323 can be more easily inserted between the two pins 810 of the coil 800 to separate the two pins 810 of the coil 800. It should be noted that, in the specific implementation process, the upper end of the separation rod 323 can also be conical, so that the separation rod 323 can also be more easily inserted between the two pins 810 of the coil 800.

[0037] It should be noted that in the actual implementation process, the straightening assembly 320 can also be provided in other manners. For example, the two clamping jaws 324 are installed on the second driving device 322, the separation rod 323 includes two separable parts that can be attached to each other, the two separable parts are in transmission connection with the second driving device 322, and the second driving device 322 can drive the two separable parts to move away from each other or move close to each other. Thus, in the process of straightening and separating the two pins 810 of the coil 800, the two separable parts are first attached to each other, and after the two separable parts are inserted between the two pins 810 of the coil 800, the second driving device 322 drives the two separable parts to move away from each other, so that the two separable parts one by one correspondingly cooperate with the two clamping jaws 324 to clamp the corresponding pins 810. Then, the first driving device 330 drives the straightening assembly 320 to move away from the fixing assembly 310, so as to separate and straighten the two pins 810 of the coil 800.

[0038] With reference to Figure 2 And Figure 5 It can be imagined that in some embodiments, the fixing assembly 310 includes a positioning seat 311 installed on the rack 100, a third driving device 312, and two first positioning columns 313. The positioning seat 311 is used for placing and positioning the coil 800, and is provided with a first avoiding hole 3111. The two first positioning columns 313 pass through the first avoiding hole 3111. The third driving device 312 is installed on the rack 100 and is in transmission connection with the two first positioning columns 313. The third driving device 312 can drive the two first positioning columns 313 to move away from or move close to each other. The two first positioning columns 313 are used for passing through the inner hole of the coil 800, and when the two first positioning columns 313 move away from each other, the two first positioning columns 313 can abut against the inner side wall of the coil 800. Specifically, in the process of conveying the coil 800 to the fixing assembly 310 for fixing by the material conveying mechanism 400, the third driving device 312 first drives the two first positioning columns 313 to move close to each other, so as to facilitate the material conveying mechanism 400 to place the main body of the coil 800 on the two first positioning columns 313, and avoid the first positioning column 313 from rubbing and damaging the inner wall of the coil 800. After the coil 800 is placed on the positioning seat 311, the third driving device 312 drives the two first positioning columns 313 to move away from each other to abut against the inner wall of the coil 800, thereby achieving the fixing of the coil 800. When the clamping mechanism 500 needs to take away the coil 800 on the positioning seat 311, the third driving device 312 drives the two first positioning columns 313 to move close to each other, so as to facilitate the clamping mechanism 500 to take out the coil 800, and avoid the first positioning column 313 from rubbing and damaging the inner wall of the coil 800. By using the above arrangement, the fixing assembly 310 can firmly fix the coil 800, so that the subsequent straightening work can be smoothly carried out.

[0039] With referenceFigure 2 And Figure 5 It can be imagined that, in some embodiments, the two first positioning columns 313 each have two positioning planes 3131 arranged at right angles, the positioning planes 3131 are used to fit the inner wall of one side of the coil 800, and the two positioning planes 3131 of one of the first positioning columns 313 are each correspondingly parallel to the two positioning planes 3131 of the other first positioning column 313, wherein the inner hole of the coil 800 is generally rectangular, and when the third driving device 312 drives the two first positioning columns 313 to move away from each other, the four positioning planes 3131 described above can be fitted with the four inner walls of the coil 800 one by one, so that the coil 800 can be precisely positioned, and the deformation of the coil 800 during the straightening of the pin 810 can be reduced.

[0040] In the specific implementation process, the material transfer mechanism 400 takes materials from the material storage station, the straightening assembly 320 straightens the pins 810 of the coil 800, and the clamping mechanism 500 clamps the coil 800 on the clamp 200, and the above-mentioned works do not affect each other, and can be carried out at the same time to improve the work efficiency.

[0041] It should be noted that, in the specific implementation process, the fixed assembly 310 described above can also be arranged in other ways, for example, the fixed assembly 310 includes a positioning seat 311, and the positioning seat 311 is provided with a containing groove for containing the main body of the coil 800. When the coil 800 is fixed, the main body of the coil 800 is placed in the containing groove, and then the coil 800 is pressed by the material transfer mechanism 400 to realize the fixation of the coil 800.

[0042] Referring to Figure 1 And Figure 3 It can be imagined that, in some embodiments, the material storage station is provided with a material storage device 610, and the material storage device 610 includes a bottom plate 611 for stacking coils 800, and the bottom plate 611 is vertically provided with a second positioning column 612 for penetrating the inner hole of the coil 800 and positioning the coil 800. Through the arrangement of the material storage device 610, the coils 800 can be regularly stored, and the material transfer mechanism 400 can conveniently hold the coils 800. In the specific implementation process, when there is no coil 800 in the storage device, the empty storage device can be taken out, and then the storage device stacked with coils 800 is placed.

[0043] Referring to Figure 3In the implementation, the pin leading-out positions of all the coils 800 penetrated by the second positioning column 612 are aligned, that is, each coil 800 is sleeved on the second positioning column 612 according to a predetermined orientation. With the implementation, the material transfer mechanism 400 can not be provided with an image sensor for determining the pin leading-out positions of the coils 800, the pin leading-out positions of the coils 800 can be determined, the control of the system is simplified, and the error in determining the pin leading-out positions of the coils 800 can be reduced.

[0044] With reference to Figure 3 and Figure 7 It is conceivable that, in some embodiments, the second positioning column 612 is provided with two second positioning columns 612 which are spaced apart and mounted on the bottom plate 611, and the gap between the two second positioning columns 612 is smaller than the length or width of the coil 800. Among all the coils 800 stacked on the bottom plate 611, one of any two adjacent coils 800 stacked above and below is sleeved on one of the second positioning columns 612, and the other is sleeved on the other second positioning column 612. Thus, the coils 800 penetrated by the two second positioning columns 612 can be staggered with each other, so that the two adjacent coils 800 stacked above and below are not attached together, effectively reducing the situation that the adjacent coils 800 are also lifted when the material transfer mechanism 400 lifts one coil 800, and the coils 800 are scattered.

[0045] With reference to Figure 3 and Figure 7 It is conceivable that, in some embodiments, the rack 100 is provided with a material lifting mechanism 620 which is located below the bottom plate 611. The bottom plate 611 is provided with a second avoiding hole 6111 through which one end of the material lifting mechanism 620 penetrates. One end of the material lifting mechanism 620 can push the coil 800 on the bottom plate 611 to rise along the second positioning column 612. With the above arrangement, the uppermost coil 800 in the storage device can be lifted to a predetermined position, so that the material transfer mechanism 400 can grasp the coil 800 at the predetermined position. Thus, the material transfer mechanism 400 is more convenient to grasp the coil 800, and the system control is facilitated.

[0046] With reference to Figure 1 and Figure 3 It is conceivable that, in some embodiments, the wireless charging coil automatic feeding equipment comprises a control device 710 which is electrically connected with the material lifting mechanism 620. The control device 710 is mounted on the rack 100. The rack 100 is provided with an inductive device 720 which is electrically connected with the control device 710. The inductive device 720 is used to induct whether the upper end of the second positioning column 612 has a coil 800. The control device 710 can control the material lifting mechanism 620 to work according to the signal of the inductive device 720. With the above arrangement, the material lifting mechanism 620 can be automatically worked to lift the coil 800 on the storage device.

[0047] In practice, the sensing device 720 can be configured as an optical proximity switch or a mechanical proximity switch.

[0048] Reference Figure 7 As can be imagined, in some embodiments, the top-feeding mechanism 620 includes a fourth drive device 621 and a lifting member 622 mounted on the frame 100. The fourth drive device 621 can drive the lifting member 622 to rise and fall. The lifting member 622 can pass through the second clearance hole 6111. A lifting plate 6221 is mounted on the upper end of the lifting member 622. The fourth drive device 621 can drive the lifting member 622 to rise, thereby causing the lifting plate 6221 to push the coil 800 on the base plate 611 to rise. The second clearance hole 6111 is in the shape of an "I" and the lifting plate 6221 is in the shape of an "I". Thus, the lifting plate 6221 can simultaneously push the coils 800 on the two second positioning posts 612 to rise. During the pushing process, the contact area between the lifting plate 6221 and the lowermost coil 800 is large, avoiding damage to the coil 800 by the lifting plate 6221.

[0049] It should be noted that the aforementioned top material mechanism 620 can also be configured in other ways. For example, the top material mechanism 620 includes a cylinder, and the cylinder push rod is equipped with a lifting plate 6221. The cylinder can push the lifting plate 6221 through the second clearance hole 6111 and then push the coil 800 on the base plate 611 to rise.

[0050] Reference Figure 1 and Figure 3 As can be imagined, in some embodiments, the material transfer mechanism 400 includes a first moving platform 410 and a first turntable 420 mounted on the frame 100. The first turntable 420 is mounted on the first moving platform 410. The first moving platform 410 can drive the first turntable 420 to rise, move horizontally, and rotate. The first moving platform 410 can drive the first turntable 420 to rotate. A plurality of material transfer suction cups 430 are mounted on the lower side of the first turntable 420. With the above configuration, the first moving platform 410 can drive the material transfer suction cups 430 to rise, move horizontally, and rotate, so that the material transfer mechanism 400 can transport the coil 800 on the storage station to the fixing component 310 for fixing.

[0051] Of course, in the specific implementation process, the material transfer mechanism 400 mentioned above can also be set in other ways. For example, the first moving platform 410 mentioned above can be replaced with a material transfer robotic arm.

[0052] Reference Figure 4In a specific implementation, the clamping mechanism 500 can include a clamping mechanical arm 510, and the first and second gripping assemblies 520 and 530 are both mounted on the clamping mechanical arm 510. Of course, the clamping mechanism 500 can also have other settings, for example, the clamping mechanical arm 510 can be replaced by a second moving platform.

[0053] With reference to Figure 4 In a specific implementation, the first gripping assembly 520 includes a plurality of clamping suction cups, or the first gripping assembly 520 includes a suction nozzle in the form of a ring.

[0054] With reference to Figure 4 In a specific implementation, the second gripping assembly 530 can include two pneumatic clamps to clamp the two pins 810 of the coil 800 respectively. Of course, in other embodiments, the second gripping assembly 530 can also have a structure similar to the straightening assembly 320, that is, the second gripping assembly 530 includes a driving device, a partition column, and two clamping pieces, the partition column is located between the two clamping pieces, and the driving device can drive the two clamping pieces to move close to or away from the partition column.

[0055] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0056] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
