Description

Technical Field

[0001] This application relates to the field of wireless charging product manufacturing equipment, and in particular to charging coil feeding devices and vehicle-mounted wireless charging component assembly lines. Background Technology

[0002] Currently, wireless charging components are mainly used for wireless charging of electronic products such as mobile phones. Existing automotive wireless charging components typically consist of a magnetic sheet and three coils attached to it. Two coils are attached to the same side of the magnetic sheet, and the third coil is attached above the two existing coils. Currently, the assembly process between the magnetic sheet and the coils is usually done by surface mounting. In existing technologies, the automation level of wireless charging component assembly equipment is insufficient. To improve production efficiency, some manufacturers use conveyor belts to feed the coils. Individual coils are laid out randomly on the conveyor belt, and a robotic arm, in conjunction with a vision positioning system, picks up the coils from the conveyor belt and feeds them into the assembly equipment, thus completing the automatic coil feeding. However, this feeding method requires very high positioning accuracy from the vision positioning system, necessitating the use of expensive vision components, resulting in high equipment costs and limiting further improvements in production efficiency. Utility Model Content

[0003] To address the issues of high equipment costs and limited production efficiency in existing robotic arms that use visual positioning systems to grasp coils for coil loading, this application provides a charging coil loading device and an in-vehicle wireless charging component assembly line.

[0004] Firstly, the charging coil feeding device provided in this application adopts the following technical solution:

[0005] A charging coil feeding device includes:

[0006] The horizontal stacking includes a storage bar and a stacking mounting base. One end of the storage bar is detachably connected to the stacking mounting base. Several charging coils are stacked in a single row and sleeved outside the storage bar. The length direction of the storage bar is consistent with the X-axis direction.

[0007] The pushing mechanism includes a pushing fork and a two-dimensional linear pushing module. The pushing fork is located below the storage bar, and the two-dimensional linear pushing module is used to drive the pushing fork to move along the X-axis and Y-axis directions so as to drive the pushing fork to push the charging coils stacked in a single row away from the storage bar one by one.

[0008] The feeding and transfer mechanism includes a suction cup robot and a two-dimensional linear feeding module. The suction cup robot is located on the side near the discharge end of the storage bar. The suction cup robot is used to suck up the charging coil located on the outermost side of the discharge end of the storage bar. The two-dimensional linear feeding module is used to drive the suction cup robot to move along the X-axis and Y-axis.

[0009] The above technical solution employs a horizontal feeding mechanism using a storage bar. A pusher fork and a two-dimensional linear feeding module work together to push the charging coils stacked on the storage bar one by one away from it. Specifically, the pusher fork pushes the entire charging coil stack along the direction of the pushing away of the charging coils, pushing a distance equal to the thickness of one charging coil at a time. The suction cup robot and the two-dimensional linear feeding module then remove the charging coil located at the outermost end of the storage bar. The storage bar can also position the charging coils strung on it, facilitating high-speed gripping of the charging coils by the suction cup robot and the two-dimensional linear feeding module. Visual positioning is not required, resulting in low equipment cost, high feeding efficiency, and a high potential for production efficiency improvement. This provides sufficient room for capacity expansion in the entire automotive wireless charging component assembly line. Furthermore, the storage bar is detachably connected to the stacking mounting base, allowing for quick replacement of the storage bar with a full stack of charging coils after the charging coils are used up, thus rapidly completing the charging coil feeding process quickly and conveniently.

[0010] Preferably, the stacking mounting base has an assembly slot for accommodating and limiting the position of the storage bar. The stacking mounting base is connected to two sets of quick-release locking components for locking the storage bar in the assembly slot. The two sets of quick-release locking components are arranged alternately along the length direction of the storage bar. Each quick-release locking component includes a locking retaining key, a plug slot, and a locking member. The plug slot is provided in the stacking mounting base. The locking member is detachably inserted into the plug slot, and the lower end face of the locking member abuts against the upper surface of the storage bar. The locking retaining key is provided in the stacking mounting base, and the locking retaining key can be moved to a designated position and abut against the free end of the locking member to prevent the locking member from disengaging from the plug slot, or the locking retaining key can be moved away from the designated position to release the restriction on the locking member.

[0011] The above technical solution allows for the rapid positioning and installation of the storage bar through the cooperation of two sets of quick-release locking components and assembly slots.

[0012] Preferably, the locking retaining key includes a connecting bolt, a compression spring sleeved outside the connecting bolt, and a swing member. The connecting bolt is screwed to the stack mounting base. One end of the swing member is rotatably sleeved outside the connecting bolt and the swing member is clamped between the compression spring and the stack mounting base. The free end of the swing member can swing to the free end of the locking member and abut against the free end of the locking member to prevent the locking member from disengaging from the insertion slot.

[0013] Preferably, the transverse stacking further includes a feeding linear module, the number of storage bars is at least two, and the storage bars are arranged alternately along the Z-axis. The stacking mounting base is located at the output end of the feeding linear module. The feeding linear module is used to drive the stacking mounting base to move along the Z-axis to complete the rotational feeding switching between the storage bars.

[0014] The above technical solution involves at least two storage bars, which are arranged alternately along the Z-axis. One storage bar is used for feeding. After the charging coil of this storage bar is consumed, the feeding linear module drives the stacking mounting base to move along the Z-axis to move the other storage bar with a fully loaded charging coil to the feeding position. The operator removes the consumed storage bar and replaces it with a storage bar with a fully loaded charging coil, thereby maintaining the machine's continuous, efficient, and uninterrupted production.

[0015] Preferably, the two-dimensional linear loading module includes an X-axis transfer linear module, a transfer mounting plate disposed at the output end of the X-axis transfer linear module, and two sets of Y-axis transfer linear modules disposed alternately on the transfer mounting plate along the X-axis direction. The corresponding number of suction cup robots is two, and the two suction cup robots are respectively disposed at the output ends of the two sets of Y-axis transfer linear modules. It also includes a parking position and a unloading position. The parking position and the unloading position are disposed alternately below the loading and transfer mechanism along the X-axis direction, and the distance between the parking position and the unloading position is equivalent to the distance between the two suction cup robots. The distance between the parking position and the discharge end of the storage bar is equivalent to the distance between the two suction cup robots. The distance between the unloading position and the storage bar is greater than the distance between the parking position and the storage bar. The parking position is provided with a positioning block for positioning the charging coil.

[0016] The above technical solution employs two suction cup robotic arms working in conjunction with the parking position to simultaneously complete the pre-positioning and loading of the charging coil. Each suction cup robotic arm shares a set of Y-axis linear transfer modules, resulting in a compact structure and high loading efficiency. The inner ring of the charging coil, which is parked at the parking position, is quickly positioned by fitting it onto the positioning block, thereby improving the loading accuracy of this application.

[0017] Preferably, the pusher fork is equipped with a feeding sensor for sensing whether the corresponding storage bar contains a charging coil.

[0018] Through the above technical solution: the feeding sensor can sense whether the corresponding storage bar has a charging coil. When it senses that there is no charging coil, the feeding linear module drives the stacking mounting base to move along the Z-axis to move another storage bar with a full charging coil to the feeding position. The operator removes the consumed storage bar and replaces it with a storage bar with a full charging coil, thereby maintaining the machine's continuous, efficient and uninterrupted production.

[0019] Preferably, the suction cup manipulator includes a rotary cylinder, a suction cup mounting frame, several suction nozzles, and a positioning block. The rotary cylinder is located at the output end of the Y-axis linear transfer module, the suction cup mounting frame is located at the output end of the rotary cylinder, the several suction nozzles are located on the suction cup mounting frame and are used to pick up the charging coil, and the positioning block is located on the suction cup mounting frame, and the surface of the positioning block opposite to the storage bar is provided with a docking part that positions and cooperates with the discharge end of the storage bar.

[0020] Preferably, the suction cup mounting bracket is provided with a vision lens for capturing images of the charging coil being picked up by the suction cup robot, and the orientation of the charging coil is determined by whether the pins in the image block the coil. A collection port for collecting charging coils that are not oriented correctly is provided below the suction cup robot.

[0021] Secondly, the vehicle-mounted wireless charging component assembly line provided in this application adopts the following technical solution:

[0022] The vehicle-mounted wireless charging component assembly line includes the aforementioned charging coil feeding device, as well as a magnetic sheet feeding device, a dual-coil bonding device, a double-sided adhesive bonding device, a top coil bonding device, a pressure holding and unloading device, an unloading conveyor belt, and a transfer fixture. The magnetic sheet feeding device, dual-coil bonding device, double-sided adhesive bonding device, and top coil bonding device are arranged sequentially and each is equipped with a conveyor belt unit. Adjacent conveyor belt units are connected end to end in sequence. Each conveyor belt unit is equipped with a transfer fixture for positioning and carrying the magnetic sheet. Both the dual-coil bonding device and the top coil bonding device are equipped with charging coil feeding devices. The suction cup robot arm of the charging coil feeding device, away from the storage bar, transfers the charging coil and bonds it to the magnetic sheet or to the dual coil.

[0023] Through the above technical solution: the charging coil feeding device is applied to the vehicle wireless charging component assembly line, which can quickly complete the feeding of charging coils and accurately attach and assemble the charging coils to the magnetic sheet. The assembly efficiency is high, and the devices are connected end to end in sequence through the conveyor belt unit. Each device can be added or removed according to the actual production process requirements.

[0024] Preferably, the suction cup robot of the dual-coil bonding device can pick up two charging coils at a time, and the suction cup robot of the top coil bonding device can pick up one charging coil at a time. The magnetic sheet feeding device is used to automatically feed the magnetic sheet and remove the release film of the magnetic sheet before placing the magnetic sheet in the corresponding transfer fixture. The charging coil feeding device of the dual-coil bonding device is used to bond two charging coils to the surface of the magnetic sheet. The double-sided tape application device is used to apply double-sided tape to the surfaces of the two charging coils located on the surface of the magnetic sheet. The charging coil feeding device of the top coil bonding device is used to bond one charging coil to the surfaces of the two charging coils and bond it with double-sided tape. The pressure holding and unloading device is used to hold pressure on the charging assembly processed by the top coil bonding device to maintain good adhesion between the charging coil and the double-sided tape, and at the same time, transfer the pressure-held charging assembly to the unloading conveyor belt.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The charging coil feeding device of this application adopts a horizontal feeding method using a storage bar. The pushing fork and the two-dimensional linear feeding module work together to push the charging coils stacked on the storage bar one by one away from the storage bar. That is, the pushing fork pushes the entire charging coil stack in the direction of pushing away the charging coils, pushing a distance of one charging coil thickness each time. The suction cup robot and the two-dimensional linear feeding module remove the charging coil located at the outermost end of the storage bar. The storage bar can position the charging coils strung on it, so that the suction cup robot and the two-dimensional linear feeding module can grasp the charging coils at high speed without visual positioning. The equipment cost is low, the feeding efficiency is high, and the production efficiency improvement limit is high, leaving enough room for the capacity improvement of the entire vehicle wireless charging component assembly line. In addition, the storage bar and the stacking mounting base are detachably connected. After the charging coils are used up, the storage bar full of charging coils can be quickly replaced to quickly complete the charging coil feeding, which is quick and convenient.

[0042] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0043] Example 1

[0044] Reference Figures 1-5 .

[0045] Reference Figure 1 The charging coil feeding device 51 includes a horizontal stacking 1, a pushing mechanism 2, and a feeding and transfer mechanism 3.

[0046] Reference Figure 1 and Figure 3The horizontal stacking unit 1 includes a storage rod 11 and a stacking mounting base 12. One end of the storage rod 11 is detachably connected to the stacking mounting base 12. Several charging coils are stacked in a single row and sleeved outside the storage rod 11, and the charging coils are connected in series outside the storage rod 11. The storage rod 11 provides circumferential pre-positioning for the charging coils. The length direction of the storage rod 11 is consistent with the X-axis direction. The stacking mounting base 12 has an assembly groove for accommodating and limiting the position of the storage rod 11. 13. The stacking mounting base 12 is connected to two sets of quick-release locking components 14 for locking the storage bar 11 into the assembly slot 13. The two sets of quick-release locking components 14 are arranged alternately along the length direction of the storage bar 11. The quick-release locking component 14 includes a locking retaining key 143, a plug slot 141, and a locking member 142. The plug slot 141 is opened in the stacking mounting base 12. The locking member 142 is detachably inserted into the plug slot 141 and the lower end face of the locking member 142 is flush with the storage bar. The upper surface of 11 abuts against the locking member 142, thereby engaging with the mounting groove 13 to lock the storage bar 11 onto the stacking mounting base 12. A locking retaining key 143 is disposed on the stacking mounting base 12, and the locking retaining key 143 can move to a designated position and abut against the free end of the locking member 142 to prevent the locking member 142 from disengaging from the insertion groove 141. Alternatively, the locking retaining key 143 can move away from the designated position to release the restriction on the locking member 142, thereby quickly releasing the lock. When the stopper 142 is in the locked state, the stopper 142 is pulled out from the insertion slot 141, which locks the storage bar 11. The storage bar 11 is removed and replaced with a storage bar 11 fully loaded with a charging coil. The stopper 142 is then inserted again. The locking retaining key 143 moves to the designated position and abuts against the free end of the stopper 142 to prevent the stopper 142 from disengaging from the insertion slot 141. This completes the locking of the new storage bar 11, allowing for quick and convenient replacement of the storage bar 11.

[0047] Reference Figure 3The locking retaining key 143 includes a connecting bolt 144, a compression spring 145 sleeved outside the connecting bolt 144, and a swing member 146. The connecting bolt 144 is screwed to the stacking mounting base 12. One end of the swing member 146 is rotatably sleeved outside the connecting bolt 144, and the swing member 146 is sandwiched between the compression spring 145 and the stacking mounting base 12. The free end of the swing member 146 can swing to the free end of the locking member 142 and abut against the free end of the locking member 142 to prevent the locking member 142 from disengaging from the insertion slot 141, thereby maintaining the locking of the storage bar 11. When the storage bar 11 needs to be replaced, push the swing member 146 outward and compress the spring 145. Swing the swing member 146 to release its contact with the locking member 142. Pull out the locking member 142 and contact the locking of the storage bar 11. Remove the storage bar 11 and replace it with a storage bar 11 fully loaded with a charging coil. Then insert the locking member 142. The locking retaining key 143 moves to the designated position and abuts against the free end of the locking member 142 to prevent the locking member 142 from disengaging from the insertion slot 141. This completes the locking of the new storage bar 11, allowing for quick and convenient replacement of the storage bar 11.

[0048] Reference Figure 1 and Figure 3 The horizontal stacking 1 also includes a feeding linear module 15. The number of storage bars 11 is at least two, and the at least two storage bars 11 are arranged alternately along the Z-axis. The stacking mounting base 12 is located at the output end of the feeding linear module 15. The feeding linear module 15 is used to drive the stacking mounting base 12 to move along the Z-axis to complete the rotational feeding switching between each storage bar 11.

[0049] Reference Figure 1The feeding mechanism 2 includes a feeding fork 22 and a feeding two-dimensional linear module 23. The feeding fork 22 is equipped with a feeding sensor 21 for sensing whether the corresponding storage bar 11 contains a charging coil. The feeding sensor 21 can sense whether the corresponding storage bar 11 contains a charging coil. When it senses that there is no charging coil, the feeding linear module 15 drives the stacking mounting base 12 to move along the Z-axis to move another storage bar 11 fully loaded with a charging coil to the feeding position. The operator removes the consumed storage bar 11 and replaces it with a storage bar 11 fully loaded with a charging coil, thereby maintaining the continuous and efficient uninterrupted production of the machine. The feeding fork 22 is located below the storage bar 11. The feeding two-dimensional linear module 23 is used to drive the feeding fork 22 to move along the X and Y axes, so as to drive the feeding fork 22 to move the single The stacked charging coils are pushed away from the storage bar 11 one by one. The pusher fork 22 and the two-dimensional linear pusher module 23 work together to push the stacked charging coils connected to the storage bar 11 away from the storage bar 11 one by one. That is, the pusher fork 22 pushes the entire stack of charging coils in the direction of pushing away the charging coils, pushing a distance of one charging coil thickness each time. The suction cup robot 32 and the two-dimensional linear loading module 31 take away the charging coil located at the outermost end of the storage bar 11. The storage bar 11 can position the charging coils connected to it so that the suction cup robot 32 and the two-dimensional linear loading module 31 can grasp the charging coils at high speed without visual positioning. The equipment cost is low, the loading efficiency is high, and the production efficiency improvement limit is high, leaving enough room for the capacity improvement of the entire vehicle wireless charging component assembly line.

[0050] Reference Figure 1 The feeding and transfer mechanism 3 includes a suction cup robot 32 and a feeding two-dimensional linear module 31. The suction cup robot 32 is located on the side near the discharge end of the storage bar 11. The suction cup robot 32 is used to suck up the charging coil located on the outermost side of the discharge end of the storage bar 11. The feeding two-dimensional linear module 31 is used to drive the suction cup robot 32 to move along the X-axis and Y-axis directions.

[0051] Reference Figure 1 and Figure 4The loading two-dimensional linear module 31 includes an X-axis transfer linear module 311, a transfer mounting plate 312 disposed at the output end of the X-axis transfer linear module 311, and two sets of Y-axis transfer linear modules 313 disposed alternately on the transfer mounting plate 312 along the X-axis direction. There are two corresponding suction cup robots 32, each disposed at the output end of one of the two sets of Y-axis transfer linear modules 313. The module also includes a parking position 41 and a unloading position 42, which are disposed alternately below the loading and transfer mechanism 3 along the X-axis direction. The spacing between the two suction cup manipulators 32 is comparable to the spacing between the two suction cup manipulators 32. The distance between the parking position 41 and the discharge end of the storage bar 11 is comparable to the spacing between the two suction cup manipulators 32. The distance between the unloading position 42 and the storage bar 11 is greater than the distance between the parking position 41 and the storage bar 11. Two suction cup manipulators 32 are used in conjunction with the parking position 41 to simultaneously complete the pre-positioning and loading of the charging coil. Each suction cup manipulator 32 shares a set of Y-axis transfer linear module 313, which has a compact structure and high loading efficiency. The inner ring of the charging coil parked at the parking position 41 is fitted onto the positioning block 324 and is quickly positioned, thereby improving the loading accuracy of this application.

[0052] Reference Figure 4 The suction cup manipulator 32 includes a rotary cylinder 321, a suction cup mounting frame 322, several suction nozzles 323, and a positioning block 324. The rotary cylinder 321 is located at the output end of the Y-axis transfer linear module 313. The suction cup mounting frame 322 is located at the output end of the rotary cylinder 321. Several suction nozzles 323 are located on the suction cup mounting frame 322 and are used to pick up the charging coil. The positioning block 324 is located on the suction cup mounting frame 322, and the surface of the positioning block 324 opposite to the storage bar 11 is provided with a docking part 325 that positions and cooperates with the discharge end of the storage bar 11. Specifically, when the feeding and transfer mechanism 3 moves the suction cup manipulator 32 close to the discharge end of the storage bar 11, the docking part 325 of the positioning block 324 cooperates and docks with the end face of the storage bar 11 to quickly complete the positioning and alignment, so that the several suction nozzles 323 can accurately pick up the charging coil.

[0053] Reference Figure 4The suction cup mounting bracket 322 is equipped with a vision lens 326 for capturing images of the charging coil picked up by the suction cup robot 32. The correct orientation of the charging coil is determined by whether the pin in the image blocks the coil. A collection port for collecting incorrectly oriented charging coils is provided below the suction cup robot 32. Specifically, the inner ring of the charging coil has a pin that extends beyond the outer ring of the coil along the surface of the coil. Thus, the vision lens 326 captures two images of the two surfaces of the coil: one is image one where the pin blocks the coil, and the other is image two where the pin does not block the coil. In actual production, image one can be taken as the correct orientation. When the vision lens 326 captures image two, it is determined that the charging coil is placed backwards. The suction cup robot 322 can directly discard the charging coil into the collection port, thereby effectively reducing the scrap rate.

[0054] Specifically, the linear modules in this application are all existing linear modules.

[0055] The implementation principle of Example 1 is as follows: Two storage bars 11 with charging coils connected in series are inserted into the stacking mounting base 12 and the storage bars 11 are quickly locked by the quick-release locking component 14. The pushing two-dimensional linear module 23 drives the pushing fork 22 to rise and extend into the space between the charging coil of the corresponding storage bar 11 closest to the stacking mounting base 12 and the stacking mounting base 12. The pushing two-dimensional linear module 23 drives the pushing fork 22 to push the charging coils of the entire storage bar 11 away from the storage bar 11 one by one. During the process of pushing them away one by one, the feeding two-dimensional linear module 31 drives the suction cup robot 32 to approach the discharge end of the storage bar 11 and take away the charging coils that are pushed away from the storage bar 11 one by one. After the charging coils are placed in the parking position 41 for positioning, they are then grabbed by another suction cup robot 32 and attached to the magnetic sheet or coil of the transfer fixture 58.
