At present, the soldering equipment generally includes a pin cutting mechanism, a soldering mechanism, and a conveying mechanism. The soldering mechanism includes a robotic arm and a tin furnace.

The frame 100 is sequentially arranged with a first cutting station, a soldering station and a second cutting station along the length direction of the conveying mechanism 210. The conveying mechanism 210 is provided with a fixture 220 for clamping the coil. The conveying mechanism 210 can sequentially convey the fixture 220 to the first cutting station, the soldering station and the second cutting station; the first cutting mechanism 310 is used to cut the pins of the coil, and the first cutting mechanism 310 is installed at the first cutting station; the soldering mechanism 400 is used to solder the pins of the coil, and the soldering mechanism 400 is installed at the soldering station; the second cutting mechanism 510 is used to cut the head of the pin of the coil after soldering, and the second cutting mechanism 510 is installed at the second cutting station. The first cutting mechanism 310 and the second cutting mechanism 510 are located on the same side of the conveying mechanism 210.

[0030] During the operation of the coil soldering equipment provided by the utility model, the conveying mechanism 210 can sequentially convey the fixture 220 with the coil to the first cutting station, the soldering station and the second cutting station, wherein the first cutting mechanism 310 can cut the pins of the coil on the first cutting station to make the pins of the coil have an appropriate length, the soldering mechanism 400 can solder the pins of the coil, and after the soldering is completed, the heads of the pins of the soldered coil can be cut by the second cutting mechanism 510, thereby preventing the pin heads of the coil from being too large and affecting subsequent welding. Among them, after the coil is cut by the second cutting mechanism 510, since the pins have been soldered, the ends of the pins will no longer be dispersed, and the solder quality of the remaining parts of the pins is good, which can be beneficial to the subsequent soldering of the pins of the coil with the circuit board, thereby ensuring product quality.

[0031] Reference Figure 2 and Figure 4 It is conceivable that, in some embodiments, a first position adjustment mechanism is provided between the first cutting mechanism 310 and the frame 100, and the first position adjustment mechanism can adjust the distance between the first cutting mechanism 310 and the fixture 220 located at the first cutting station; a second position adjustment mechanism 700 is provided between the second cutting mechanism 510 and the frame 100, and the second position adjustment mechanism 700 can adjust the distance between the second cutting mechanism 510 and the fixture 220 located at the second cutting station.

[0032] Reference Figure 2 and Figure 4 It is conceivable that in some embodiments, the first position adjustment mechanism and the second position adjustment mechanism 700 are both configured as multi-degree-of-freedom mobile platforms, so that the first position adjustment mechanism can drive the first cutting mechanism 310 to move along the width direction of the conveying mechanism 210 to adjust the distance between the first cutting mechanism 310 and the corresponding fixture 220, and the first position adjustment mechanism can also adjust the position of the first cutting mechanism 310 along at least one of the length direction, up-down direction, etc. of the conveying mechanism 210; the second position adjustment mechanism 700 can drive the first cutting mechanism 310 to move along the width direction of the conveying mechanism 210 to adjust the distance between the second cutting mechanism 510 and the corresponding fixture 220, and the second position adjustment mechanism 700 can also adjust the position of the second cutting mechanism 510 along at least one of the length direction, up-down direction, etc. of the conveying mechanism 210. With the above configuration, the positions of the first cutting mechanism 310 and the second cutting mechanism 510 can be flexibly adjusted according to actual conditions.

[0033] Reference Figure 4 Specifically, in some embodiments, the first position adjustment mechanism may include a first cross slide 610, the first cutting mechanism 310 may be installed on the first cross slide 610, and the first cross slide 610 may drive the first cutting mechanism 310 to move along the width direction of the conveying mechanism 210 and the length direction of the conveying mechanism 210.

[0034] Reference Figure 4 It is conceivable that, in some embodiments, in the specific implementation process, the first position adjustment mechanism may include an angle adjustment device 620, the angle adjustment device 620 is installed on the first cross slide 610, and the first cutting mechanism 310 is installed on the angle adjustment device 620, thereby, the first position adjustment mechanism can also adjust the angle position of the first cutting mechanism 310 through the angle adjustment device 620.

[0035] It should be noted that the first position adjustment mechanism can also be set up in other ways. For example, the first position adjustment mechanism includes a first horizontal movable platform, and the first cutting mechanism 310 is installed on the first horizontal movable platform. The first horizontal movable platform can drive the first cutting mechanism 310 to move along the width direction of the conveying mechanism 210 to adjust the distance between the first cutting mechanism 310 and the corresponding clamp 220. With the above setting, the coil soldering equipment can also meet the working needs.

[0036] Reference Figure 2 Specifically, in some embodiments, the second position adjustment mechanism 700 may include a second horizontal movable platform 720 and a second cross slide 710, the second horizontal movable platform 720 is installed on the frame 100, the second cross slide 710 is installed on the second horizontal movable platform 720, and the second cutting mechanism 510 can be installed on the second cross slide 710, wherein the second cross slide 710 can drive the second cutting mechanism 510 to move along the width direction and the up and down direction of the conveying mechanism 210, and the second horizontal movable platform 720 can drive the second cutting mechanism 510 to move along the length direction of the conveying mechanism 210.

[0037] It should be noted that the second position adjustment mechanism 700 can also be set up in other ways. For example, the second horizontal movable platform 720 can be installed on the second cross slide 710, and the second cross slide 710 can be installed on the frame 100. With the above setting, the coil soldering equipment can also meet the working needs.

[0038] Reference Figure 2 and Figure 4It is conceivable that, in some embodiments, the conveying mechanism 210 is provided with guide baffles 211 for guiding the clamp 220 on both sides in the width direction, the first cutting station is provided with a first interception mechanism 320, and the second cutting station is provided with a second interception mechanism 520, wherein when the conveying mechanism 210 conveys the clamp 220, the clamp 220 slides along the guide baffle 211, the first interception mechanism 320 can stop the clamp 220 at the first cutting station, and the second interception mechanism 520 can stop the clamp 220 at the second cutting station, so that the first interception mechanism 320 The mechanism 320 can temporarily retain the fixture 220 at the first cutting station, and the guide baffles 211 on both sides of the conveying mechanism 210 can cooperate with each other to position the fixture 220, thereby ensuring the cutting accuracy of the first cutting mechanism 310. The second intercepting mechanism 520 can retain the fixture 220 at the second cutting station, and the guide baffles 211 on both sides of the conveying mechanism 210 can cooperate with each other to position the fixture 220, thereby ensuring the cutting accuracy of the second cutting mechanism 510. The above-mentioned arrangement can ensure that the retained length of the pins of the coil after two cuts meets the use requirements.

[0039] Reference Figure 2 and Figure 4It is conceivable that, in some embodiments, the first interception mechanism 320 includes a first drive device 321 and a first pressure plate 322, the first drive device 321 is installed on the frame 100 and is connected to the first pressure plate 322, the first pressure plate 322 is located on the upper side of the conveying mechanism 210, and the first drive device 321 can drive the first pressure plate 322 to rise and fall to loosen or press the clamp 220 located on the first cutting station; the second interception mechanism 520 includes a second drive device 521 and a second pressure plate 522, the second drive device 521 is installed on the frame 100 and is connected to the second pressure plate 522, the second pressure plate 522 is located on the upper side of the conveying mechanism 210, and the second drive device 521 can drive the second pressure plate 522 to rise and fall to loosen or press the clamp 220 located on the second cutting station. With the above arrangement, the first retaining mechanism 320 can stop the clamp 220 on the first cutting station. After the first cutting mechanism 310 completes the shearing work, the first retaining mechanism 320 drives the first pressure plate 322 to rise through the first driving device 321, thereby releasing the clamp 220 on the first cutting station, so that the clamp 220 on the first cutting station can be transported to the next station by the conveying mechanism 210; the second retaining mechanism 520 can stop the clamp 220 on the second cutting station. After the second cutting mechanism 510 completes the shearing work, the second retaining mechanism 520 drives the second pressure plate 522 to rise through the second driving device 521, thereby releasing the clamp 220 on the second cutting station, so that the clamp 220 on the second cutting station can be transported to the next station by the conveying mechanism 210. Among them, through the cooperation of the guide baffles 211 on both sides of the conveying mechanism 210 and the first intercepting mechanism 320, the clamp 220 on the first cutting station can be positioned in three axes, thereby improving the cutting accuracy of the first cutting mechanism 310; through the cooperation of the guide baffles 211 on both sides of the conveying mechanism 210 and the second intercepting mechanism 520, the clamp 220 on the second cutting station can be positioned in three axes, thereby improving the cutting accuracy of the second cutting mechanism 510.

[0040] It should be noted that the above-mentioned first intercepting mechanism 320 can be set up in other ways. For example, the first pressure plate 322 can be replaced by an electromagnet. The material of at least part of the clamp 220 is a magnetic material such as iron or magnetic ceramics. The first driving device 321 can raise and lower the height position of the electromagnet so that the distance between the electromagnet and the clamp 220 is less than the height of the guide baffle 211. Therefore, when the clamp 220 needs to stay at the first cutting station, the electromagnet works and the electromagnet can suck the clamp 220 up to separate the clamp 220 from the conveying mechanism 210. Among them, the clamp 220 is still partially located between the guide baffles 211 on both sides of the conveying mechanism 210. The guide baffles 211 on both sides of the conveying mechanism 210 can still position the clamp 220. After the first cutting mechanism 310 completes the shearing work, the electromagnet releases the clamp 220.

[0041] It should be noted that the second intercepting mechanism 520 may be arranged in other ways. For example, the second pressure plate 522 may be replaced by an electromagnet by referring to the arrangement of the first intercepting mechanism 320 .

[0042] Reference Figure 2 and Figure 3 It is conceivable that, in some embodiments, the second cutting mechanism 510 includes a third driving device 511 and two cutter heads 512 distributed up and down, the third driving device 511 is located on the side of the cutter head 512 away from the conveying mechanism 210, the third driving device 511 is in transmission connection with the two cutter heads 512, and the third driving device 511 can drive the two cutter heads 512 to move relative to each other to get closer or farther away, wherein the blades 5121 of the two cutter heads 512 are arranged in a horizontal direction, and after the two cutter heads 512 get closer to each other, the blades 5121 of the two cutter heads 512 are flush with each other and in contact. With the above arrangement, when the second cutting mechanism 510 is cutting the pins of the coil, the blades 5121 of the two cutter heads 512 are always kept parallel to each other, which can reduce the bending of the pins of the coil when cutting the pins of the coil, so that the second cutting mechanism 510 can accurately cut the pins of the coil, and the bending of the pins of the coil after cutting is less, and the cutting quality is good. After the second cutting mechanism 510 completes cutting, the third driving device 511 drives the two cutting heads 512 to move away from each other, thereby avoiding the pins of the coil and preventing the second cutting mechanism 510 from affecting the conveying mechanism 210 in conveying the coil.

[0043] Reference Figure 2 In the specific implementation process, in order to ensure the shearing quality and accuracy of the second cutting mechanism 510, the shearing speed of the second cutting mechanism 510 can be slowed down. In addition, in order to ensure work efficiency, the above-mentioned second cutting mechanism 510 can be provided with more than two, and the more than two second cutting mechanisms 510 are arranged at intervals along the length direction of the conveying mechanism 210. Therefore, the more than two second cutting mechanisms 510 can work at the same time. In this way, the work efficiency can be guaranteed while ensuring the shearing quality and accuracy.

[0044] Reference Figure 4 Specifically, in some embodiments, the first cutting mechanism 310 includes scissors 311 and a fourth driving device 312 for driving the scissors 311 to work. Since the second cutting mechanism 510 is required to cut the pins of the coil later, during the operation, the first cutting mechanism 310 can sacrifice cutting accuracy and perform cutting work at a faster speed.

[0045] Of course, it is conceivable that the second cutting mechanism 510 may also be configured in the same manner as the first cutting mechanism 310 to ensure cutting accuracy and cutting efficiency.

[0046] It should be noted that the first cutting mechanism 310 and the second cutting mechanism 510 may also be configured in other ways. For example, the first cutting mechanism 310 and the second cutting mechanism 510 may be configured as a water jet cutting machine or a laser cutting machine.

[0047] Reference Figure 1 It is conceivable that, in some embodiments, the soldering mechanism 400 includes a soldering robot arm 410 and a tin furnace 420, and the soldering robot arm 410 and the tin furnace 420 are arranged along the width direction of the conveying mechanism 210, and the soldering robot arm 410 is located on the side of the conveying mechanism 210 away from the first cutting mechanism 310. Therefore, after the soldering mechanism 400 completes soldering, the orientation of the pins of the coil clamped on the fixture 220 can remain unchanged before and after soldering, making the connection between the first cutting, soldering, second cutting and other tasks more compact.

[0048] Reference Figure 1 It is conceivable that, in some embodiments, the frame 100 is provided with a laser peeling device 800, the laser peeling device 800 and the first cutting mechanism 310 are located on the same side of the conveying mechanism 210, and the laser peeling device 800 is located between the soldering mechanism 400 and the first cutting mechanism 310. With the above arrangement, the laser peeling device 800 removes the insulating paint on the pins of the coil so that the soldering mechanism 400 can subsequently solder the pins of the coil.

[0049] Reference Figure 1 It is conceivable that, in some embodiments, the rack 100 is provided with a cooling device 900, which is used to cool the pins of the coil. The cooling device 900 and the laser peeling device 800 are located on the same side of the conveying mechanism 210, and the cooling device 900 is located between the laser peeling device 800 and the soldering mechanism 400. With the above arrangement, after the laser peeling device 800 completes its work, the cooling device 900 can cool the pins of the coil, speed up the cooling speed, and facilitate the subsequent soldering of the pins of the coil by the soldering mechanism 400.

[0050] In the specific implementation process, the cooling device 900 can be set as a water spray device, and the fixture 220 is provided with an absorbent that can absorb and accumulate water. The absorbent can be set as a sponge, a towel, etc. The absorbent is in contact with the pins of the coil. Therefore, the cooling device 900 adds water to the pins of the coil that has been laser peeled to cool the pins of the coil. During the water addition process, the absorbent can absorb water. When the soldering mechanism 400 completes the soldering, the absorbent that absorbs water can be used to cool the pins of the coil, thereby increasing the cooling speed, so that the coil after the soldering can enter the next process faster. In addition, during the soldering process, the pins that are wetted with water can adhere to the tin better, thereby improving the quality of the soldering.

[0051] It should be noted that, in a specific implementation process, the above-mentioned cooling device 900 can also be configured as an air cooling device.

[0052] It can be imagined that since the first cutting mechanism 310, the second cutting mechanism 510, the laser peeling device 800 and the cooling device 900 are all located on the same side of the conveying mechanism 210, when the conveying mechanism 210 conveys the coil to these devices, the orientation of the pins of the coils clamped on the fixture 220 can remain unchanged. Therefore, the coil soldering equipment does not need to be equipped with a device for changing the orientation of the pins, and the working connection between the various devices of the coil soldering equipment is more compact, which can improve production efficiency.

[0053] It is conceivable that, in the specific implementation process, the above-mentioned conveying mechanism 210 may include more than two belt conveyors, and the more than two belt conveyors cooperate in conveying the fixture clamped with the coil in sequence. Among them, the soldering mechanism 400 is located between the corresponding two adjacent belt conveyors. During the operation of the soldering mechanism 400, the soldering robot arm 410 grabs the fixture 220 clamped with the coil from the previous belt conveyor, and the soldering robot arm 410 immerses the pins of the coil into the tin liquid of the tin furnace 420 for soldering. After the soldering is completed, the soldering robot arm 410 puts the fixture 220 clamped with the coil on the next belt conveyor.

[0054] It should be noted that the above-mentioned conveying mechanism 210 may also be arranged in other ways. For example, the above-mentioned belt conveying device may be replaced by a roller conveying device.

[0055] According to the wireless charger production line of the second embodiment of the utility model, it includes the above-mentioned coil soldering equipment. In the specific implementation process, the wireless charger production line includes assembly equipment and drying equipment. The coil soldering equipment solders the pins of the coil. After the second cutting mechanism 510 cuts the pins of the coil, the coil is transported to the assembly equipment, and then the assembly equipment assembles the coil and the magnetic plate together in a bonding manner, and then the semi-finished product after assembly is transported to the drying equipment for drying. Among them, the coil soldering equipment can cut the head of the pin of the coil after soldering through the second cutting mechanism 510, thereby preventing the pin head of the coil from being too large to affect the subsequent welding of the pin of the coil and the circuit board, thereby ensuring the product quality of the wireless charger.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
