[0002] Most electric shavers on the market currently consist of a stainless steel mesh cover, an inner blade, a micro motor, a power source, and a housing. The power source of an electric shaver usually uses a rechargeable battery, and its power supply to the micro motor is controlled by a circuit board. Therefore, for the convenience of simplifying the structure and reducing wire connections, the ear of the battery can be directly welded to the circuit board.

[0003] Since the circuit board of a shaver product needs to install a rechargeable battery, the traditional process is to manually hold a soldering gun to individually weld two battery ears, and then conduct manual current detection, manual inspection of the charging light, and manual marking of defective products for distinction. This workflow is slow and the welding is uneven, and it is difficult to control the amount of solder. Moreover, the employee repeats the same action in a cycle, resulting in a large labor intensity, and problems such as false soldering and missed soldering often occur, the quality cannot be guaranteed, and the efficiency is extremely low. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

It is only for the convenience of describing the present invention and does not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Since the circuit board of a razor product needs to be installed with a rechargeable battery, the traditional process is to manually hold a soldering gun to individually solder two battery ear tabs, and then perform manual current detection, manual inspection of the charging light, and manual marking of defective products for distinction. This workflow is slow and the soldering is uneven. It is difficult to control the amount of solder, and the efficiency is extremely low.

[0025] In view of this, the present invention provides a processing device for a battery and a circuit board. Figure 1-12 For an embodiment of the processing device for a battery and a circuit board provided by the present invention, please refer to Figure 1-12 , the processing device 100 is composed of a mounting rack 1 and a conveying device 2, a welding device 3, a detection device 4, etc. fixed on the mounting rack 1.

[0026] The mounting rack 1 is generally in the shape of a cabinet and has a cabinet door that can be opened and closed to prevent dust and static electricity from affecting the internal equipment. One of the conveying platforms of the mounting rack 1 is horizontally arranged on the cabinet surface and extends along its length direction. From right to left, the conveying platform is provided with a loading station 1a, a welding station 1b, a detection station 1c, and an unloading station 1d at intervals.

[0027] Please refer to Figure 1 and Figure 6, the processing device 100 further includes a plurality of mounting jigs 6. Each mounting jig 6 can be rotated among the respective stations in turn, and cyclically displaced in order from the loading station 1a → welding station 1b → inspection station 1c → unloading station 1d → loading station 1a. Moreover, multiple mounting jigs 6 can be rotated simultaneously. In this embodiment, mounting jigs 6 are placed on each station, and the battery 8 and the circuit board 7 of each mounting jig 6 are processed, transferred, or inspected at the corresponding stations simultaneously.

[0028] The main body of the mounting jig 6 is in a square shape and is distributed in the horizontal direction. An installation position 6a corresponding to the outer contour design of the circuit board 8 is designed in the hollow part, and a support part 61 is designed below the hollow part (i.e., the installation position 6a). The preliminarily fixed battery 7 and circuit board 8 can enter the installation position 6a, the battery 7 abuts against the support part 61, and the installation position 6a limits the circuit board 8 in the horizontal direction, thereby further fixing the battery 7 and the circuit board 8. It should be noted that the circuit board 8 is provided with a clamping frame for fixing the battery 7, and the tab of the battery 7 passes through the circuit board 8 and is exposed outward for welding and inspection.

[0029] In this embodiment, each mounting jig 6 has 1 installation position 6a for limiting the whole large uncut circuit board, and each circuit board 7 of the large circuit board is welded, inspected, and unloaded in turn at the corresponding stations. Of course, the implementation mode of the present invention is not limited to this. Each mounting jig 6 has several installation positions 6a, and several cut circuit boards 8 are placed corresponding to each installation position 6a. When processing the circuit boards 8 in the mounting jig 6 at the station, welding, inspection, and unloading need to be performed in turn on the circuit boards corresponding to each installation position 6a.

[0030] The conveying device 2 is provided corresponding to the conveying table on the mounting rack 1, and there are various driving forms of its first driving mechanism 21. For example, for a rotary table type conveying table, the first driving mechanism 21 can drive the rotary table to rotate through equipment such as a motor, thereby driving the mounting jig 6 to switch among the loading station 1a, welding station 1b, inspection station 1c, and unloading station 1d in turn. It can also adopt a method such as an endless conveyor belt, and can also realize the movement of the mounting jig 6 on the same plane. In this embodiment, since the conveying table where the stations are set extends along its length direction, it is preferably to use a conveyor belt to convey the mounting jig 6.

[0031] The welding device 3 is fixed on the mounting rack 1 and is correspondingly arranged directly above the welding station 1b. Similar to some existing soldering devices, the welding device 3 has a solder wire and its wire feeding device, as well as a soldering gun, which can solder the connection between the circuit board 8 and the tab of the rechargeable battery 7, so that the rechargeable battery 7 and its tab can be directly electrically connected to the circuit board 8, reducing the design of wire connection. Since the welding operation takes longer than the detection time, in this embodiment, two sets of welding devices 3 are arranged on the mounting rack 1.

[0032] The detection device 4 is also fixed on the mounting rack 1 and is correspondingly arranged directly above the detection station 1c. In this embodiment, due to the direction limitation of the transfer table and its stations, the welding device 3, the detection device 4, etc. are fixed in sequence along approximately the same direction. The welding device 3 and the detection device 4 are both fixed on the same cross beam above their corresponding stations. The detection device 4 is provided with a plurality of detection heads 411, and the probes of each detection head 411 can abut against the contacts on the circuit board 8 to supply power to the circuit board 8. During the detection process, the current and voltage data of the circuit board 8 can be measured, as well as whether the rechargeable battery 7 is in a charging state, thereby being able to indicate the reliability of the welding between the tab of the battery 7 and the circuit board 8. In this embodiment, these data can be judged by the charging indicator light on the circuit board 8 and detected by a light sensor, and the charging result is fed back to the outside to prompt the operator.

[0033] The above devices are all controlled by a controller. The controller is electrically connected to each device to control the operation of each device. It should be noted that the controller is usually composed of a processing chip and its connected circuits, which can receive electrical signals and process and feedback the signals.

[0034] In this embodiment, a display and an alarm (not shown in the figure) are further included. The display can display the data measured by the detection device 4 and the feedback information, and the alarm can prompt the abnormal operation of each device. The working principle is not described in detail here.

[0035] It should be understood that the processing device 100 is powered by the mains power supply.

[0036] In the technical solution of the present invention, the circuit board 8 equipped with the rechargeable battery 7 is placed on the mounting fixture 6 manually or by a machine, and then the transfer device 2 is used to alternately switch the mounting fixture 6 between each station, and the operations of welding, detecting, and unloading the circuit board 8 on the mounting fixture 6 after switching stations are performed. Multiple circuit boards 8 on the mounting fixtures 6 can be processed simultaneously, greatly improving the working efficiency, with a high degree of automation, and eliminating manual detection, ensuring the qualified rate and improving the welding quality.

[0037] To realize the conversion of the mounting fixture 6 between each station, please refer to Figure 7In this embodiment, the mounting frame 1 includes a double-layer conveyor platform, and the two conveyor platforms are parallel to each other and are horizontally arranged along their length directions. The upper conveyor platform 11 is used for the circulation of the mounting fixture 6 equipped with the circuit board 8 between various stations, and the lower conveyor platform 12 is used for the circulation of idle mounting fixtures 6. In some other embodiments, the loading station 1a, the welding station 1b, the inspection station 1c and the unloading station 1d can be arranged in any order in the double-layer conveyor platform, that is, some stations are on one of the double-layer conveyor platforms, and some stations are on the other double-layer conveyor platform. Of course, the number of conveyor platforms is not limited, and can be designed as a three-layer conveyor platform, a four-layer conveyor platform, etc.

[0038] Further, to drive the installation fixture 6 to move on the double-layer conveyor, please refer to Figure 5 The first driving mechanism 21 includes a first driving member 211 and a second driving member 212. The first driving member 211 can drive any layer of the double-layer conveying platform of the installation fixture 6 to perform horizontal movement, and the second driving member 212 can drive the installation fixture 6 to perform lifting movement between the double-layer conveying platforms.

[0039] In some specific embodiments, the first driving member 211 includes a plurality of first conveyor belts 2111 and a plurality of second conveyor belts 2112 arranged in the horizontal direction, and there are at least two first conveyor belts 2111, which are respectively arranged below the upper conveyor platform 11 and the lower conveyor platform 12. Of course, the first conveyor belt 2111 on each conveyor platform can also be composed of multiple components, as long as the conveyor belts are arranged close to each other.

[0040] It should be noted that the first conveyor belt 2111 and the second conveyor belt 2112 are a kind of micro conveyor belt commonly seen in the market, which has the advantages of miniaturization and high precision. The servo motor cooperates with the reducer or micro gear box to drive the active roller (not shown in the figure) to rotate slowly. Under the action of friction, the active roller drives the driven roller and the conveyor belt to run, and the conveyor belt drives the installation fixture 6 to move slowly and accurately through friction. The second driving member 212 is a linear motion device such as an electric push rod, an electric cylinder, etc., and one or more can be provided to drive the installation fixture 6 to move between the double-layer conveyor platforms.

[0041] Since the rightmost side of the upper conveying platform 11 is the loading station 1a, and the leftmost side is the unloading station 1d, in order to realize that the installation fixture 6 can be moved in sequence from the detection station 1c→unloading station 1d→loading station 1a→welding station 1b, in this embodiment, the loading station 1a and the unloading station 1d are respectively provided with a second conveyor belt 2112. The electric push rod (that is, the second driving member 212) is also respectively arranged at the loading station 1a and the unloading station 1d, and its driving end is connected or transmission-connected to the second conveyor belt 2112.

[0042] When the installation fixture 6 moves from the detection station 1c to the unloading station 1d, that is, after the first conveyor belt 2111 moves the installation fixture 6 to the second conveyor belt 2112, the second driving member 212 drives the second conveyor belt 2112 to descend to the lower conveyor table 12. Then, the second conveyor belt 2112 moves the installation fixture 6 to the first conveyor belt 2111 on the lower conveyor table 12. The first conveyor belt 2111 on the lower conveyor table 12 continues to move the installation fixture 6 to the second conveyor belt 2112 corresponding to the loading station 1a at the lower layer. Finally, the second driving member 212 raises the second conveyor belt 2112 to the upper conveyor table 11, thus completing the process from the unloading station 1d to the loading station 1a. The second conveyor belt 2112 corresponding to the loading station 1a then moves the installation fixture 6 to the first conveyor belt 2111 on the upper conveyor table 11, and then enters the welding station 1b and the detection station 1c in sequence.

[0043] In the above embodiments, at the loading station 1a, a manual or mechanical method can be selected to place the circuit board 8 equipped with the rechargeable battery 7 on the installation fixture 6. When the manual method is not efficient enough, after the first conveyor belt 2111 on the lower conveyor table 12 moves the installation fixture 6 to the second conveyor belt 2112 corresponding to the loading station 1a, the second conveyor belt 2112 can directly send the empty installation fixture 6 to the outside, and then the installation fixture 6 with the circuit board 8 placed on it can be placed on the loading station 1a manually. Similarly, at the unloading station 1d, a manual or mechanical method can also be selected.

[0044] Please refer to Figure 5 , and it should be noted that light sensors 9 are provided at each station. When the installation fixture 6 enters one of the stations, the light sensor detects that there is an installation fixture 6 above it, and then immediately starts the devices (welding device 3, detection device 4) above the station to work.

[0045] To prevent the installation fixture 6 from shifting on the conveyor belt when the first conveyor belt 2111 and the second conveyor belt 2112 drive the installation fixture 6, in an embodiment of the present invention, the conveying device 2 further includes guide rails 22 provided on both sides of each first conveyor belt 2111 and each second conveyor belt 2112. The frame of the square installation fixture 6 can contact the guide rails 22 and slide relative to them, thereby restricting the shift of the installation fixture 6 on the conveyor belt.

[0046] To enable the welding device 3 to better weld the circuit board 8 at the welding station 1b, please refer to Figure 8, in this embodiment, the soldering mechanism includes a soldering gun 31, a second driving mechanism 32, and a solder wire conveying mechanism 33. The second driving mechanism 32 includes a third driving member 321 and a fourth driving member 322. The third driving member 321 is fixed on the cross beam of the mounting frame 1. The driving end of the third driving member 321 is directly or indirectly connected to the fourth driving member 322, and the driving end of the fourth driving member 322 is directly or indirectly connected to the soldering gun 31. The installation position of the solder wire conveying mechanism 33 is not restricted. In a more detailed embodiment, a first mounting plate 34 is fixedly connected to the driving end of the third driving member 321, and both the fourth driving member 322 and the solder wire conveying mechanism 33 are fixed on the first mounting plate 34.

[0047] When the mounting fixture 6 enters the welding station 1b, the fourth driving member 322 drives the soldering gun 31 to descend to the position to be welded, and starts to solder the circuit board 8 and the battery tab 7 on the mounting fixture 6. After the welding of the previous circuit board 8 is completed, the fourth driving member 322 drives the soldering gun 31 to lift, and the third driving member 321 drives the fourth driving member 322 to horizontally displace along the arrangement direction of each circuit board 8 to the position above the next circuit board 8. Then the fourth driving member 322 drives the soldering gun 31 to descend to the position to be welded of this circuit board 8 again, and repeats the operation until the welding of all the circuit boards 8 and their battery tabs 7 on the same mounting fixture 6 is completed. And after the welding is completed, the fourth driving member 322 drives the soldering gun 31 to lift, and the third driving member 321 drives the fourth driving member 322 and the connected soldering gun 31 back to the initial position.

[0048] Furthermore, in order to convey the solder wire to the soldering gun 31, please refer to Figure 9 and 10 , the solder wire conveying mechanism 33 includes a solder wire roller 331 fixed on the first mounting plate 34 and a wire feeding mechanism 332. The wire feeding mechanism 332 feeds the coiled solder wire on the solder wire roller 331 into the soldering gun 31, and the gun head heats and melts the solder wire to perform soldering on the position to be welded. Among them, the wire feeding mechanism 332 includes a conveying roller 3321 rotatably mounted on the first mounting plate 34 and a driving motor 3322. The driving motor 3322 drives the conveying roller 3321 to rotate, and thus can continuously draw the solder wire and feed it into the soldering gun 31.

[0049] It should be noted that, for providing more accurate displacement control, please refer to Figure 9, in this embodiment, the third driving member 321 is a linear motor, and its driving end can move precisely in the horizontal direction; the fourth driving member 322 is a micro conveyor belt, and the micro conveyor belt is fixedly connected to the driving end of the linear motor through the first mounting plate 34. The servo motor of the micro conveyor belt and the driving-connected driving roller and driven roller are mounted on the first mounting plate 34, and the conveyor belt of the micro conveyor belt can move in the up and down direction during driving. Among them, the soldering gun 31 is indirectly fixed to a slider 342 through a connecting rod 343, and the slider 342 is fixedly connected to the conveyor belt, so that the slider 342 can slide up and down relative to the slide rail 341 on the first mounting plate 34, and further enables the soldering gun 31 to move up and down.

[0050] The third driving member 321 adopts a linear motor, which ensures the accuracy of the soldering gun 31 at the welding positions of two adjacent circuit boards, but cannot ensure its accuracy in the length direction of the same circuit board. In this embodiment, the soldering gun 31 is fixedly connected to the connecting rod 343 through a first adjusting plate (not shown in the figure). One end of the soldering gun 31 is connected to a lead screw on the first adjusting plate. The lead screw extends along the length direction of the same circuit board, and nuts on both sides of the end rotate on the lead screw to fix the two ends of the end, thereby adjusting the position accuracy of the soldering gun 31 in this direction.

[0051] Please refer to Figure 11 , in an embodiment of the present invention, the detection device 4 includes a detection mechanism 41 and a third driving mechanism 42. The third driving mechanism 42 includes a fifth driving member 421 and a sixth driving member 422. Among them, the fifth driving member 421 is fixed on the cross beam of the mounting frame 1, and the driving end of the fifth driving member 421 is directly or indirectly connected to the fourth driving member 322, and the driving end of the fourth driving member 322 is directly or indirectly connected to the detection mechanism 41. In a more detailed embodiment, a second mounting plate 44 is fixedly connected to the driving end of the sixth driving member 422, and the detection mechanism 41 is fixed on the second mounting plate 44. The detection mechanism 41 has a plurality of detection heads 411 for electrically connecting to the circuit board 8, and the probes of each detection head 411 can abut against the contacts on the circuit board 8 to supply power to the circuit board 8.

[0052] In a more preferred embodiment, the detection device 4 further includes a marking mechanism 43. The marking mechanism 43 includes a marking head 431. When the detection head 411 detects, if the light sensor detects that the charging indicator light on the circuit board 8 is not on, it is determined that the welding is unqualified, and the circuit board 8 is marked. The marking mechanism 43 and the detection mechanism 41 are both fixedly connected to the second mounting plate 44.

[0053] During specific operation, when the installation fixture 6 enters the detection station 1c, the sixth driving member 422 drives the second mounting plate 44 and the connected detection mechanism 41 to descend to the contacts of the circuit board 8, and starts to detect the circuit board 8 on the installation fixture 6. After the detection of the previous circuit board 8 is completed, the sixth driving member 422 drives the second mounting plate 44 to lift, and the fifth driving member 421 drives the fourth driving member 322 to horizontally displace along the arrangement direction of each circuit board 8 to above the next circuit board 8 to be detected. Then, the sixth driving member 422 drives the second mounting plate 44 and the connected detection mechanism 41 to descend to the contacts of this circuit board 8 again, and the operation is repeated until the detection of all the circuit boards 8 and the battery 7 pole lugs on the same installation fixture 6 is completed. Moreover, after the detection is completed, the sixth driving member 422 drives the second mounting plate 44 to lift, and the fifth driving member 421 drives the sixth driving member 422 and the connected detection mechanism 41 and marking mechanism 43 back to the initial position.

[0054] It should be noted that, in order to provide more accurate displacement control, in this embodiment, the fifth driving member 421 is a linear motor, and its driving end can move precisely in the horizontal direction; the sixth driving member 422 is an electric cylinder, the cylinder body of the electric cylinder is fixedly connected to the driving end of the linear motor, and the electric cylinder drives the piston rod of the cylinder to move up and down by changing the air pressure, so as to be able to drive the second mounting plate 44 and the connected detection mechanism 41 and marking mechanism to lift and lower in the up and down direction.

[0055] The fifth driving member 421 adopts a linear motor, which ensures the accuracy of the detection mechanism 41 and the marking mechanism 43 at the detection positions of two adjacent circuit boards, but cannot ensure its accuracy in the length direction of the same circuit board. In this embodiment, the common end of the detection mechanism 41 and the marking mechanism 43 is fixedly connected to the second mounting plate 44 through a second adjusting plate (not shown in the figure). This end is connected to a lead screw on the second adjusting plate. The lead screw extends along the length direction of the same circuit board, and nuts on both sides of this end rotate on the lead screw to fix both ends of this end, so as to adjust the position accuracy of the detection mechanism 41 and the marking mechanism 43 in this direction.

[0056] Please refer to Figure 12 , in an embodiment of the present invention, the processing device 100 further includes a discharging device 5. The discharging device 5 is fixed above the discharging station 1d of the mounting rack 1. The discharging device 5 includes an electromagnetic fixture 51 and a fourth driving mechanism 52. The fourth driving mechanism 52 includes a seventh driving member 521 and an eighth driving member 522. Among them, the seventh driving member 521 is fixed on the vertical beam of the mounting rack 1, the driving end of the seventh driving member 521 is directly or indirectly connected to the fourth driving member 322, and the driving end of the fourth driving member 322 is directly or indirectly connected to the electromagnetic fixture 51. In a more detailed embodiment, a third mounting plate 53 is fixedly connected to the driving end of the seventh driving member 521, and the eighth driving member 522 is fixed on the third mounting plate 53.

[0057] Further, the electromagnetic fixture 51 includes two electromagnetic clamping blocks 512 that are opposite and spaced apart in the horizontal direction, a sensor, and an electronic control device 511 electrically connected to the sensor and the electromagnetic clamping blocks 512. The electronic control device 511 is configured to control the energization and de-energization of the two electromagnetic clamping blocks 512 according to the signal of the sensor.

[0058] During specific operation, when the installation jig 6 enters the unloading station 1d, the eighth driving member 522 drives the electromagnetic fixture 51 to descend above the installation jig 6. The electromagnetic clamping blocks 512 of the electromagnetic fixture 51 are just located between the circuit board 8 and the installation jig 6 at the clamping notch 6b (the circuit board in the figure is not cut and can be clamped as a whole). When the sensor (located inside the electronic control device and not shown in the figure) of the electromagnetic fixture 51 detects the circuit board 8 of the installation jig 6 below, it feeds back to the electronic control device 511, and the electronic control device 511 controls the relative movement of the electromagnetic clamping blocks 512 to clamp the entire circuit board 8. Then, the eighth driving member 522 drives the entire electromagnetic fixture 51 to rise, and the seventh driving member 521 drives the eighth driving member 522 and the circuit board 8 clamped by its electromagnetic fixture 51 to move horizontally. When transferring the circuit board 8 to other production lines, the eighth driving member 522 drives the electromagnetic fixture 51 to descend, and the electromagnetic clamping blocks 512 of the electromagnetic fixture 51 release the circuit board 8, thus completing one unloading operation. The seventh driving member 521 drives the eighth driving member 522 and its electromagnetic fixture 51 back above the next circuit board 8 to be transferred, and repeats the above operations until all the circuit boards 8 on the same installation jig 6 are transferred. And after the unloading is completed, the eighth driving member 522 drives the electromagnetic fixture 51 to lift, and the seventh driving member 521 drives the eighth driving member 522 and the connected electromagnetic fixture 51 back to the initial position.

[0059] To provide more precise displacement control, in this embodiment, the seventh driving member 521 is a linear motor, and its driving end can move precisely in the horizontal direction; the eighth driving member 522 is an electric cylinder or an electric push rod. The main body of the electric push rod is fixedly connected to the third mounting plate 53, and the electric cylinder drives the piston rod of the cylinder to move up and down by changing the air pressure, so as to be able to drive the electromagnetic fixture 51 to lift and lower in the vertical direction.

[0060] It should be noted that the driving end of the eighth driving member 522 is fixedly connected to the electronic control device of the electromagnetic fixture 51. The two electromagnetic clamping blocks 512 of the electromagnetic fixture 51 are slidably mounted directly below the electronic control device. After the two electromagnetic clamping blocks 512 are energized, the magnetic poles are opposite or the same, so as to move relatively or in the opposite direction to clamp or release the circuit board 8. The sensor is connected to the electronic control device and can detect whether there is a circuit board 8 below.

[0061] The present invention also proposes a control method for a processing device 100 of a battery and a circuit board. The control method includes the following steps: After the controller issues an opening instruction, the second conveyor belt 2112 and the first conveyor belt 2111 of the conveying device 2 sequentially move the mounting jig 6 at the loading station 1a to the welding station 1b. When the light sensor 9 detects that the mounting jig 6 is at the welding station 1b, it sends a welding instruction to the welding device 3. After the welding device 4 receives the welding instruction, the welding gun 31 descends and starts welding the circuit board 8 and the battery tabs of the battery 7 on the mounting jig 6 in sequence. After the welding device 3 finishes welding, the first conveyor belt 2111 of the conveying device 2 moves the mounting jig 6 at the welding station 1b to the inspection station 1c. When the light sensor 9 detects that the mounting jig 6 is at the inspection station 1c, it sends an inspection instruction to the inspection device 4. After the inspection device 4 receives the inspection instruction, the inspection mechanism 41 starts to inspect the circuit board 8 on the mounting jig 6 in sequence. When it is found that the rechargeable battery 8 cannot be charged through the circuit board 7, the marking mechanism 43 marks the circuit board. After the inspection device 4 finishes the inspection, the first conveyor belt 2111 and the second conveyor belt 2112 of the conveying device 2 sequentially move the mounting jig 6 at the inspection station 1c to the unloading station 1d. After unloading is completed, the second driving member 212, the second conveyor belt 2112, the first conveyor belt 2111, and the second conveyor belt 2112 of the conveying device 2 sequentially move the mounting jig 6 at the unloading station 1d back to the loading station 1a.

For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
