Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and in particular relates to a battery and circuit board processing device. Background Technology

[0002] Most electric shavers on the market today consist of a stainless steel mesh cover, inner blades, a miniature motor, a power supply, and a housing. The power source for electric shavers is typically a rechargeable battery, which powers the miniature motor via a circuit board. Therefore, to simplify the structure and reduce wiring connections, the battery terminals can be directly soldered onto the circuit board.

[0003] Because the circuit board of shaver products needs to house rechargeable batteries, the traditional process involves manually soldering the two battery terminals one by one using a soldering gun. This is followed by manual current testing, checking the charging indicator light, and marking defective products for identification. This workflow is slow, results in uneven soldering, and makes it difficult to control the amount of solder. Furthermore, the repetitive nature of this process is physically demanding, leading to frequent issues like cold solder joints and missed solder joints, compromising quality and resulting in extremely low efficiency. Utility Model Content

They are only for the convenience of describing this utility model and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0048] Because the circuit board of shaver products needs to install rechargeable batteries, the traditional process involves manually soldering the two battery tabs one by one with a soldering gun, followed by manual current testing, manual inspection of the charging indicator, and manual marking of defective products. This workflow is slow, the soldering is uneven, the amount of solder is difficult to control, and the efficiency is very low.

[0049] In view of this, the present invention provides a processing apparatus for batteries and circuit boards. Figure 1-12 For an embodiment of the battery and circuit board processing apparatus provided by this utility model, please refer to [link / reference]. Figure 1-12 The processing device 100 consists of a mounting frame 1 and a conveying device 2, a welding device 3, and a testing device 4 fixed on the mounting frame 1.

[0050] Mounting rack 1 is shaped like a cabinet and has doors that can be opened and closed to protect the internal equipment from dust and static electricity. One of the conveyor tables of mounting rack 1 is horizontally positioned on the cabinet surface and extends along its length. From right to left, the conveyor table is provided with a loading station 1a, a welding station 1b, an inspection station 1c, and an unloading station 1d at intervals.

[0051] Please see Figure 1 and Figure 6The processing device 100 also has multiple mounting fixtures 6, each of which can be switched between various workstations in turn, sequentially moving from loading station 1a → welding station 1b → inspection station 1c → unloading station 1d → loading station 1a. Multiple mounting fixtures 6 can be switched simultaneously. In this embodiment, each workstation has a mounting fixture 6, and the battery 8 and circuit board 7 of each mounting fixture 6 are simultaneously processed, transferred, or inspected at the corresponding workstation.

[0052] The main body of the mounting fixture 6 is rectangular and horizontally distributed. Its hollow section has mounting positions 6a designed to correspond to the outline of the circuit board 8. A support portion 61 is located below the hollow section (i.e., mounting position 6a). The initially fixed battery 7 and circuit board 8 can enter the mounting position 6a, with the battery 7 abutting against the support portion 61. The mounting position 6a horizontally limits the circuit board 8, further securing the battery 7 and circuit board 8. It should be noted that the circuit board 8 has a clamping frame for fixing the battery 7, with the battery 7's tabs passing through the circuit board 8 and protruding outwards for easy soldering and testing.

[0053] In this embodiment, each mounting fixture 6 has one mounting position 6a for positioning the entire uncut large circuit board. Each circuit board 7 of the large circuit board is sequentially welded, inspected, and unloaded at its corresponding workstation. Of course, the embodiments of this utility model are not limited to this. Each mounting fixture 6 may have several mounting positions 6a, and several cut circuit boards 8 are placed corresponding to each mounting position 6a. When processing the circuit boards 8 in the mounting fixture 6 at each workstation, sequential welding, inspection, and unloading are required on the circuit boards corresponding to each mounting position 6a.

[0054] The conveying device 2 is set on the conveyor platform corresponding to the mounting frame 1, and its first drive mechanism 21 can be driven in various ways. For example, a turntable conveyor platform can be used, in which case the first drive mechanism 21 can drive the turntable to rotate through a motor or other equipment, thereby driving the mounting fixture 6 to switch between the loading station 1a, welding station 1b, inspection station 1c, and unloading station 1d. Alternatively, a circular conveyor belt can be used, which can also realize the movement of the mounting fixture 6 on the same plane. In this embodiment, since the conveyor platform of the setting station extends along its length, a conveyor belt is preferably used to transport the mounting fixture 6.

[0055] The welding device 3 is fixed on the mounting frame 1 and positioned directly above the welding station 1b. Similar to some existing soldering equipment, the welding device 3 has solder wire and its feeding device, as well as a soldering gun, which can solder the connection between the circuit board 8 and the tabs of the rechargeable battery 7, so that the rechargeable battery 7 and its tabs can be directly electrically connected to the circuit board 8, reducing the design of wire connections. Since the welding operation takes longer than the inspection time, in this embodiment, two sets of welding devices 3 are provided on the mounting frame 1.

[0056] The testing device 4 is also fixed on the mounting bracket 1, positioned directly above the testing station 1c. In this embodiment, due to the directional limitations of the conveyor and its station, the welding device 3, testing device 4, etc., are fixed sequentially along roughly the same direction, with both the welding device 3 and testing device 4 fixed on the same crossbeam above their respective stations. The testing device 4 is equipped with several testing heads 411, the probes of which can contact the contacts on the circuit board 8 to supply power to the circuit board 8. During the testing process, the current and voltage data of the circuit board 8, as well as whether the rechargeable battery 7 is charging, can be measured, thereby indicating the reliability of the welding between the battery 7 tabs and the circuit board 8. In this embodiment, these data can be determined by the charging indicator light on the circuit board 8 and detected by a light sensor, feeding back the charging results to the outside world to alert the operator.

[0057] All of the above devices are controlled by a controller, which is electrically connected to each device and controls the operation of each device. It should be noted that the controller typically consists of a processing chip and its connected circuitry, capable of receiving electrical signals, processing the signals, and providing feedback.

[0058] In this embodiment, a display and an alarm (not shown in the figure) are also included. The display can show the data measured by the detection device 4 and the feedback information, and the alarm can alert to abnormal operation of each device. The working principle of the alarm will not be described in detail here.

[0059] It should be understood that the processing device 100 is powered by mains power.

[0060] In the technical solution of this utility model, the circuit board 8 equipped with the rechargeable battery 7 is placed on the mounting fixture 6 by manual labor or machine. Then, the mounting fixture 6 is switched between various workstations by the conveying device 2. The circuit board 8 on the mounting fixture 6 after the workstation is switched is welded, inspected and unloaded. The circuit board 8 on multiple mounting fixtures 6 can be processed at the same time, which greatly improves the work efficiency, has a high degree of automation, reduces manual inspection, ensures the yield rate and improves the welding quality.

[0061] To enable the installation fixture 6 to be switched between different workstations, please refer to [link / reference]. Figure 7In this embodiment, the mounting frame 1 includes a double-layer conveyor system, with the two conveyor systems parallel to each other and horizontally arranged along their length. The upper conveyor system 11 is used for the transfer of the mounting fixture 6 containing the circuit board 8 between various workstations, while the lower conveyor system 12 is used for the transfer of idle mounting fixtures 6. In other embodiments, the loading station 1a, welding station 1b, inspection station 1c, and unloading station 1d can be arbitrarily arranged in sequence within the double-layer conveyor system; that is, some workstations are located on one of the double-layer conveyor systems, and some conveyor systems are located on the other. Of course, the number of conveyor systems is not limited, and it can be designed as a three-layer conveyor system, a four-layer conveyor system, etc.

[0062] Furthermore, for instructions on driving the installation fixture 6 to move on the double-layer conveyor, please refer to [link to documentation]. Figure 5 The first drive mechanism 21 includes a first drive member 211 and a second drive member 212. The first drive member 211 can drive either layer of the double-layer conveyor table of the mounting fixture 6 to move horizontally, and the second drive member 212 can drive the mounting fixture 6 to move up and down between the double-layer conveyor tables.

[0063] In some specific embodiments, the first driving component 211 includes a plurality of first conveyor belts 2111 and a plurality of second conveyor belts 2112 arranged horizontally. 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, each conveyor platform can also consist of multiple first conveyor belts 2111, as long as the conveyor belts are arranged close together.

[0064] It should be noted that the first conveyor belt 2111 and the second conveyor belt 2112 are common miniature conveyor belts on the market, with the advantages of miniaturization and high precision. They are driven by a servo motor in conjunction with a reducer or a micro gearbox to rotate the drive roller (not shown in the figure) at a slow speed. Under the action of friction, the drive roller drives the driven roller and the conveyor belt to move. The conveyor belt drives the mounting fixture 6 to move slowly and precisely through friction. The second driving component 212 is a linear motion device such as an electric push rod or an electric cylinder. One or more such devices can be provided to drive the mounting fixture 6 to move between the double-layer conveyor tables.

[0065] Since the rightmost position of the upper conveyor platform 11 is the loading station 1a and the leftmost position is the unloading station 1d, in order to enable the installation fixture 6 to move sequentially from the inspection station 1c → unloading station 1d → loading station 1a → welding station 1b, in this embodiment, a second conveyor belt 2112 is provided at both the loading station 1a and the unloading station 1d. An electric push rod (i.e., a second driving component 212) is also respectively installed at the loading station 1a and the unloading station 1d, and its driving end is connected to or driven by the second conveyor belt 2112.

[0066] When the installation fixture 6 moves from the inspection 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 drive unit 212 drives the second conveyor belt 2112 to descend to the lower conveyor platform 12. Then, the second conveyor belt 2112 moves the installation fixture 6 to the first conveyor belt 2111 of the lower conveyor platform 12. The first conveyor belt 2111 of the lower conveyor platform 12 continues to move the installation fixture 6 to the second conveyor belt 2112 located on the lower level corresponding to the loading station 1a. Finally, the second drive unit 212 lifts the second conveyor belt 2112 to the upper conveyor platform 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 of the upper conveyor platform 11, and then sequentially enters the welding station 1b and the inspection station 1c.

[0067] In the above embodiments, at the loading station 1a, either manual or mechanical methods can be used to mount the circuit board 8 with the rechargeable battery 7 on the mounting fixture 6. When manual methods are inefficient, the mounting fixture 6 can be moved from the first conveyor belt 2111 of the lower conveyor platform 12 to the second conveyor belt 2112 corresponding to the loading station 1a. The second conveyor belt 2112 then directly sends the empty mounting fixture 6 to the outside, where it can be manually placed onto the loading station 1a. Similarly, at the unloading station 1d, either manual or mechanical methods can be used.

[0068] Please see Figure 5 Additionally, it should be noted that each workstation is equipped with a light sensor 9. When the installation fixture 6 enters one of the workstations, the light sensor detects that the installation fixture 6 is above it, and then starts the device (welding device 3, detection device 4) above that workstation.

[0069] To prevent the mounting fixture 6 from shifting on the conveyor belts when the first conveyor belt 2111 and the second conveyor belt 2112 drive the mounting fixture 6, in one embodiment of the present invention, the conveying device 2 further includes guide rails 22 disposed on both sides of each first conveyor belt 2111 and each second conveyor belt 2112. The frame of the square mounting fixture 6 can contact and slide relative to the guide rails 22, thereby limiting the shift of the mounting fixture 6 on the conveyor belts.

[0070] To ensure that the welding device 3 can better weld the circuit board 8 at welding station 1b, please refer to [link / reference needed]. Figure 8In this embodiment, the soldering mechanism includes a solder gun 31, a second driving mechanism 32, and a solder wire feeding 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 to the crossbeam 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. The driving end of the fourth driving member 322 is directly or indirectly connected to the solder gun 31. The mounting position 6a of the solder wire feeding mechanism 33 is unrestricted. In a more detailed embodiment, the driving end of the third driving member 321 is fixedly connected to a first mounting plate 34, and both the fourth driving member 322 and the solder wire feeding mechanism 33 are fixed to the first mounting plate 34.

[0071] When the mounting fixture 6 enters the soldering station 1b, the fourth drive unit 322 drives the solder gun 31 to descend to the soldering position, beginning the soldering of the circuit board 8 and battery 7 tabs on the mounting fixture 6. After the previous circuit board 8 is soldered, the fourth drive unit 322 drives the solder gun 31 to rise, and the third drive unit 321 drives the fourth drive unit 322 to move horizontally along the arrangement direction of each circuit board 8, above the next circuit board 8. The fourth drive unit 322 then drives the solder gun 31 to descend to the soldering position of that circuit board 8 again, repeating the operation until all circuit boards 8 and their battery 7 tabs on the same mounting fixture 6 are soldered. After soldering is completed, the fourth drive unit 322 drives the solder gun 31 to rise, and the third drive unit 321 drives the fourth drive unit 322 and its connected solder gun 31 back to the initial position.

[0072] Furthermore, in order to feed solder wire to solder gun 31, please refer to... Figure 9 and 10 The solder wire feeding mechanism 33 includes a solder wire roller 331 fixed to 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 solder gun 31. The gun head heats and melts the solder wire and solders the area to be soldered. The wire feeding mechanism 332 includes a conveying roller 3321 rotatably mounted on the first mounting plate 34 and a drive motor 3322. The drive motor 3322 drives the conveying roller 3321 to rotate, thereby continuously pulling the solder wire and feeding it into the solder gun 31.

[0073] It should be noted that for more precise displacement control, please refer to [link / reference needed]. Figure 9In this embodiment, the third driving component 321 is a linear motor, whose driving end can move precisely in the horizontal direction; the fourth driving component 322 is a miniature conveyor belt, which is fixedly connected to the driving end of the linear motor via the first mounting plate 34. The servo motor of the miniature conveyor belt and its driven active roller and driven roller are mounted on the first mounting plate 34, and the conveyor belt of the miniature conveyor belt can move in the vertical direction during driving. The solder gun 31 is indirectly fixed to a slider 342 via a connecting rod 343. The slider 342 is fixedly connected to the conveyor belt, thereby allowing the slider 342 to slide up and down relative to the slide rail 341 on the first mounting plate 34, thus enabling the solder gun 31 to move up and down.

[0074] The third drive unit 321 uses a linear motor, which ensures the accuracy of the solder gun 31 at the soldering points of two adjacent circuit boards, but cannot guarantee its accuracy along the length of the same circuit board. In this embodiment, the solder gun 31 is fixedly connected to the first adjusting plate (not shown in the figure) and the connecting rod 343. One end of the solder gun 31 is connected to a lead screw on the first adjusting plate. The lead screw extends along the length of the same circuit board and is fixed by nuts on both sides of the end of the lead screw, thereby adjusting the positional accuracy of the solder gun 31 in this direction.

[0075] Please see Figure 11 In one embodiment of this utility model, 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, wherein the fifth driving member 421 is fixed on the crossbeam 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, the driving end of the sixth driving member 422 is fixedly connected to a second mounting plate 44, 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 electrical connection with 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.

[0076] In a more preferred embodiment, the detection device 4 further includes a marking mechanism 43, which includes a marking head 431. When the detection head 411 is detecting, if the light sensor detects that the charging indicator light on the circuit board 8 is not lit, it determines that the soldering is unqualified and marks the circuit board 8. Both the marking mechanism 43 and the detection mechanism 41 are fixedly connected to the second mounting plate 44.

[0077] In practice, when the mounting fixture 6 enters the testing station 1c, the sixth drive unit 422 drives the second mounting plate 44 and its connected testing mechanism 41 to descend to the contact point of the circuit board 8, starting the testing of the circuit board 8 on the mounting fixture 6. After the previous circuit board 8 is tested, the sixth drive unit 422 drives the second mounting plate 44 to rise, and the fifth drive unit 421 drives the fourth drive unit 322 to move horizontally along the arrangement direction of each circuit board 8, to above the next circuit board 8 to be tested. The sixth drive unit 422 then drives the second mounting plate 44 and its connected testing mechanism 41 to descend to the contact point of that circuit board 8 again, repeating the operation until all circuit boards 8 and their battery 7 tabs on the same mounting fixture 6 have been tested. After the test is completed, the sixth drive unit 422 drives the second mounting plate 44 to rise, and the fifth drive unit 421 drives the sixth drive unit 422 and its connected testing mechanism 41 and marking mechanism 43 to return to the initial position.

[0078] It should be noted that, in order to provide more precise displacement control, in this embodiment, the fifth driving component 421 is a linear motor, whose driving end can move precisely in the horizontal direction; the sixth driving component 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, thereby driving the second mounting plate 44 and its connected detection mechanism 41 and standardization mechanism to move up and down in the vertical direction.

[0079] The fifth driving component 421 uses a linear motor, which ensures the accuracy of the detection mechanism 41 and the marking mechanism 43 at the points to be detected on two adjacent circuit boards, but cannot guarantee their accuracy along the length 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 adjusting plate (not shown in the figure) and the second mounting plate 44. This end is connected to a lead screw on the second adjusting plate. The lead screw extends along the length of the same circuit board and is fixed by nuts on both sides of the end, thereby adjusting the positional accuracy of the detection mechanism 41 and the marking mechanism 43 in this direction.

[0080] Please see Figure 12In one embodiment of this utility model, the processing device 100 further includes an unloading device 5, which is fixed above the unloading station 1d of the mounting frame 1. The unloading device 5 includes an electromagnetic clamp 51 and a fourth driving mechanism 52. The fourth driving mechanism 52 includes a seventh driving member 521 and an eighth driving member 522. The seventh driving member 521 is fixed on the vertical beam of the mounting frame 1, and the driving end of the seventh driving member 521 is directly or indirectly connected to the fourth driving member 522. The driving end of the fourth driving member 522 is directly or indirectly connected to the electromagnetic clamp 51. In a more detailed embodiment, the driving end of the seventh driving member 521 is fixedly connected to a third mounting plate 53, and the eighth driving member 522 is fixed on the third mounting plate 53.

[0081] Furthermore, the electromagnetic clamp 51 includes two electromagnetic clamping blocks 512 arranged horizontally opposite to each other and spaced apart, 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 used to control the two electromagnetic clamping blocks 512 to be energized and de-energized according to the signal from the sensor.

[0082] In specific operation, when the mounting fixture 6 enters the unloading station 1d, the eighth drive unit 522 drives the electromagnetic clamp 51 to descend above the mounting fixture 6. The electromagnetic clamping block 512 of the electromagnetic clamp 51 is positioned at the clamping notch 6b between the circuit board 8 and the mounting fixture 6 (the circuit board in the figure is not cut and can be clamped as a whole). When the sensor of the electromagnetic clamp 51 (located in the electronic control device, not shown in the figure) detects the circuit board 8 of the mounting fixture 6 below, it feeds back to the electronic control device 511. The electronic control device 511 controls the relative movement of the electromagnetic clamping block 512, thereby clamping the entire circuit board 8. Then, the eighth drive unit 522 drives the entire electromagnetic clamp 51 to rise, and the seventh drive unit 521 drives the eighth drive unit 522 and the circuit board 8 clamped by the electromagnetic clamp 51 to move horizontally. When the circuit board 8 is transferred to another production line, the eighth drive unit 522 drives the electromagnetic clamp 51 to descend, and the electromagnetic clamping block 512 of the electromagnetic clamp 51 releases the circuit board 8, thus completing one unloading operation. The seventh drive unit 521 drives the eighth drive unit 522 and its electromagnetic clamp 51 back above the next circuit board 8 to be transferred, and repeats the above operation until all circuit boards 8 on the same mounting fixture 6 have been transferred. After unloading, the eighth drive unit 522 drives the electromagnetic clamp 51 to lift, and the seventh drive unit 521 drives the eighth drive unit 522 and its connected electromagnetic clamp 51 back to the initial position.

[0083] To provide more precise displacement control, in this embodiment, the seventh drive component 521 is a linear motor, whose drive end can move precisely in the horizontal direction; the eighth drive component 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, thereby driving the electromagnetic clamp 51 to move up and down in the vertical direction.

[0084] It should be noted that the drive end of the eighth drive component 522 is fixedly connected to the electronic control device of the electromagnetic clamp 51. The two electromagnetic clamping blocks 512 of the electromagnetic clamp 51 are slidably installed directly below the electronic control device. After being energized, the magnetic poles of the two electromagnetic clamping blocks 512 are opposite or the same, thereby moving relative to each other or in opposite directions to clamp or release the circuit board 8. The sensor is connected to the electronic control device and can detect whether the circuit board 8 is present below.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
