Description

Technical Field

[0001] The present invention relates to the field of supercapacitors, and in particular to an automatic sorting device and a sorting method for button-type supercapacitors. Background Art

[0002] Button-type supercapacitors are small, button-shaped energy storage devices. They can charge and discharge rapidly, achieving efficient energy storage and release. Due to their compact size and excellent performance, they are primarily used in space-sensitive applications requiring rapid energy replenishment or short-term power supply maintenance. They are widely used in electronic devices and portable instruments.

[0003] Aging and sorting are key steps in the button-type supercapacitor production process. Simply put, the capacitors are placed on an aging template for charging and aging testing. The voltage and internal resistance of the charged capacitors are then measured, and the products are classified based on the test results. After charging, a product is considered defective if its released voltage falls below a certain value. Capacitors are classified into different categories based on internal resistance within a certain range.

[0004] Currently, this inspection and sorting process relies primarily on manual labor. Workers operate testing instruments, inspecting each particle individually. They then distinguish good quality products based on the test results and classify capacitors with different internal resistances. This manual inspection method has numerous drawbacks. Firstly, the manual process is cumbersome, production efficiency is extremely low, and it consumes a significant amount of manpower and time. Secondly, manual sorting is prone to misjudgments and missed detections due to factors such as fatigue, making it difficult to ensure consistent inspection results and accurate sorting results.

[0005] In summary, there is an urgent need to develop an efficient and accurate automated sorting equipment to improve the sorting efficiency and accuracy of button-type supercapacitors. Summary of the Invention

DETAILED DESCRIPTION

[0017] It should be noted that the directions or positional relationships indicated by terms such as “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention; in addition, the terms “first”, “second” and “third” are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0018] like Figure 1As shown, the present invention provides an automated button-type supercapacitor sorting device, comprising a frame 1, a detection unit 2, a sorting unit 3, and a control system mounted on the frame 1. The detection unit 2 can simultaneously detect multiple supercapacitors 4 and feed the detection results back to the control unit. Based on the detection results, the control unit controls the sorting unit 3 to release qualified supercapacitors 4 at predetermined locations, achieving automated sorting.

[0019] like Figure 2 As shown, the detection part 2 includes an aging template 21, a detection plate 22, a detection plate linear actuator 23, a detection platform 24, a platform linear actuator 25 and a detector 26.

[0020] like Figure 3 As shown, the supercapacitor 4 is button-shaped. To facilitate batch testing, the following Figure 4 The aging template 21 shown is a storage tray for supercapacitors 4. It is equipped with M×N capacitor storage holes 211 arranged in a matrix, where M is the number of rows and N is the number of columns. Each capacitor storage hole 211 can accommodate one supercapacitor 4. Theoretically, M and N are any natural numbers greater than 1. In practice, if the values of M and N are too small, the number of items sorted at a time is small, and the efficiency of the automated sorting device cannot be fully utilized. If the values of M and N are too large, the device installation accuracy is extremely high, the detection difficulty increases significantly, and it is easy to miss detections.

[0021] In the preferred solution of this embodiment, the number of rows M and the number of columns N of the capacitor storage holes 211 are both 10, that is, a 10×10 matrix layout is adopted, and a total of 100 capacitor storage holes 211 are set to balance detection efficiency and detection difficulty.

[0022] The detection plate 22 is connected to the frame 1 through the detection plate linear actuator 23, and is configured to be controlled to perform vertical lifting and lowering motion relative to the frame 1; the detection platform 24 located below the detection plate 22 is connected to the frame 1 through the platform linear actuator 25, and is configured to be controlled to perform horizontal lateral movement and position maintenance relative to the frame 1. It should be pointed out that the detection plate linear actuator 23 and the platform linear actuator 25 are reciprocating linear motion components, and their optional types include: direct drive elements such as cylinders, pneumatic slides, hydraulic cylinders, hydraulic slides, servo electric cylinders, linear motors, or rotation-linear conversion mechanisms such as crank slider mechanisms, gear rack mechanisms, cam mechanisms, and ball screw mechanisms. In the detection process, the horizontal lateral movement and position maintenance of the detection platform 24 and the vertical lifting and lowering of the detection plate 22 need to be precisely controlled, and each action must strictly follow the action sequence logic.

[0023] Three working positions are set within the stroke of the platform linear actuator 25, namely: loading position, detection position and suction position. The loading position, detection position and suction position are respectively located at the leftmost end, middle and rightmost end of the stroke of the platform linear actuator 25. When the platform linear actuator 25 is in the loading position, the aging template 21 containing the supercapacitor 4 can be very conveniently placed on the detection platform 24; when the platform linear actuator 25 is in the detection position, the detection platform 24 is located directly below the detection plate 22, and the detection plate 22 can be pressed down to accurately contact all supercapacitors 4; when the platform linear actuator 25 is in the suction position, the supercapacitors 4 on the detection platform 24 can be very conveniently adsorbed by the sorting part 3. Limit blocks 242 for positioning the aging template 21 are also set around the detection platform 24.

[0024] like Figure 4-5 As shown, the detection board 22 is provided with an upper contact 221, and the detection platform 24 is provided with a lower contact 241; the number and distribution of the upper contacts 221 and the lower contacts 241 are consistent with the number and distribution of the capacitor storage holes 211 on the aging template 21.

[0025] like Figure 6 As shown, the sorting part 3 includes: a suction plate 31 , a vertical linear actuator 32 , a horizontal linear actuator 33 , a funnel 34 and a collection frame 35 .

[0026] The suction plate 31 is fixedly mounted on a vertical linear actuator 32, which is in turn fixedly mounted on a horizontal linear actuator 33, which is in turn fixedly mounted on the frame 1. The vertical linear actuator 32 allows the suction plate 31 to be raised and lowered vertically relative to the frame 1, and the horizontal linear actuator 33 allows the suction plate 31 to be moved horizontally and held in position relative to the frame 1. It should also be noted that the vertical linear actuator 32 and the horizontal linear actuator 33 are reciprocating linear motion components. During the sorting process, the suction plate 31's horizontal movement, position retention, and vertical lifting require precise control, and each action must adhere to a strict sequential logic.

[0027] The suction plate 31 is provided with suction devices 311. The number and distribution of suction devices 311 are consistent with the number and distribution of capacitor storage holes 211 on the aging template 21. The suction devices 311 can absorb or release supercapacitors 4 under the control of a suction control element. It should be noted that the suction devices 311 have controllable suction capabilities. Optional types include vacuum chucks, electromagnetic chucks, electrostatic chucks, electrically controlled permanent magnetic chucks, and other suction devices, as well as gripping devices such as gripping mechanical fingers.

[0028] The horizontal linear actuator 33 has multiple calibrated positions within its travel, each corresponding to a different numerical condition. Therefore, the number of sorting categories of the supercapacitor 4 determines the number of calibrated positions and, therefore, the stroke length of the horizontal linear actuator 33. For ease of description, the calibrated positions within the travel of the horizontal linear actuator 33 are denoted from left to right as calibrated position 1, calibrated position 2, and so on to calibrated position n.

[0029] The calibration position 1 at the leftmost end of the horizontal linear actuator's 33 travel is directly above the suction position. At this calibration position, the suction plate descends to complete the suction of all supercapacitors 4. Furthermore, a funnel 34 is fixedly mounted below each calibration position to receive supercapacitors 4 that have been released by the suction device and naturally fallen. A collection frame 35 is placed directly below the funnel 34 to collect the released supercapacitors 4.

[0030] In the preferred embodiment of this invention, both the test plate linear actuator 23 and the vertical linear actuator 32 utilize pneumatic cylinders, while both the platform linear actuator 25 and the horizontal linear actuator 33 utilize pneumatic slides (integrated horizontal cylinders and linear guides). This balances transmission precision with engineering-friendly automated control. The vertical movement of the test plate linear actuator 23 and the vertical linear actuator 32 is controlled by the first and third solenoid valves, respectively. The lateral movement and position retention of the platform linear actuator 25 and the horizontal linear actuator 33 are controlled by the second and fourth solenoid valves, respectively. Furthermore, the suction device 311 utilizes vacuum cups to accommodate the weak magnetic properties of supercapacitors. Solenoid valves are used as the suction control elements of the suction device 311, with 100 vacuum cups independently controlled one-to-one by 100 fifth solenoid valves.

[0031] like Figure 7 As shown, the control part includes: position sensor, main controller, microcontroller and I / O controller.

[0032] The main controller can communicate with the microcontroller. During the detection process, the main controller controls the microcontroller to select the supercapacitors 4 at different locations (i.e., establish an electrical connection between the supercapacitors 4 and the detector 26). The detector 26 can read the electrical parameters of the supercapacitors 4 (such as voltage and internal resistance) and transmit the read electrical parameters to the main controller. The main controller judges and classifies the electrical parameters of the supercapacitors 4 at each location according to a preset program (for example, if the voltage is below a certain value, the supercapacitor 4 is deemed unqualified, and if the internal resistance value is different, the supercapacitors 4 are classified into several categories). Based on this, an information matrix containing the location information and the judgment results is generated.

[0033] In the preferred solution of this embodiment, the main controller uses an STM32H7 single-chip microcomputer, and the microcontroller uses an STM32F1 single-chip microcomputer.

[0034] In the preferred embodiment of this invention, a matrix scanning method is used to select the supercapacitor 4. Specifically, each row of upper contacts 221 is connected to the output of a solid-state relay, whose input is connected to the positive measuring terminal of the detector 26; each column of lower contacts 241 is connected to the output of a solid-state relay, whose input is connected to the negative measuring terminal of the detector 26. The microcontroller selects and controls a solid-state relay connected to the upper contacts 221 (i.e., closes its output circuit) and simultaneously selects and controls a solid-state relay connected to the lower contacts 241. At this point, the supercapacitor 4 connected between the upper contacts 221 of the selected row and the lower contacts 241 of the selected column establishes a complete electrical connection path with the detector 26. The microcontroller program ensures that only one row solid-state relay and one column solid-state relay are selected at any one time to prevent detection conflicts. To ensure detection accuracy, the control unit uses a method of averaging multiple measurements. After the microcontroller activates a row of solid-state relays, establishing a stable connection between the supercapacitor 4 at the corresponding position and the detector 26, the main controller instructs the detector 26 to read the target electrical parameters (such as voltage and internal resistance) of that supercapacitor 4 ten times in a row. The main controller calculates the arithmetic average of these 10 readings and uses this average as the final test value for the current supercapacitor 4. After completing the test for that supercapacitor 4, the main controller activates the next supercapacitor 4 and repeats the measurement and averaging process.

[0035] Position sensors are installed at the three working positions within the stroke of the platform linear actuator 25, all calibration positions within the stroke of the horizontal linear actuator 33, and the starting and end points of the stroke of the detection plate linear actuator 23 and the vertical linear actuator 32 to read the position information of each linear actuator.

[0036] In a preferred solution of this embodiment, the position sensor is a magnetic switch.

[0037] The I / O controller's input channels are connected to various position sensors, and its output channels are connected to various solenoid valves. When the linear actuator reaches a predetermined position, the position sensor sends a trigger signal back to the I / O controller. Based on this feedback signal and a pre-set program, the main controller issues instructions to the I / O controller, controlling the on / off status of the specified output channel, thereby actuating the solenoid valve. By switching the air circuits open and closed by the solenoid valves, the following actuators are coordinated and controlled: ① the raising and lowering of the detection plate linear actuator 23; ② the horizontal movement or position retention of the platform linear actuator 25; ③ the raising and lowering of the vertical linear actuator 32; ④ the horizontal movement or position retention of the horizontal linear actuator 33; and ⑤ the on / off switching of the suction device 311.

[0038] The present invention also provides a button-type supercapacitor automatic sorting method, which uses the button-type supercapacitor automatic sorting device provided by an embodiment of the present invention and includes the following steps.

[0039] S1: placing an aging template 21 containing 10 rows and 10 columns of supercapacitors 4 on a detection platform 24 located at a loading position.

[0040] S2: The main controller issues a command to the I / O controller, controlling the on / off status of a specified output channel. This causes the second solenoid valve to switch the air path, causing the inspection platform 24 to move rightward along with the platform linear actuator 25. When the inspection platform 24 moves rightward to the inspection position, a trigger signal generated by the position sensor at that position is fed back to the I / O controller input port. Based on this feedback signal, the main controller controls the first and second solenoid valves to switch the air paths, causing the inspection platform 24 to stop moving. Simultaneously, the inspection plate 22 is pressed downward along with the inspection plate linear actuator 23.

[0041] S3: When the detection plate linear actuator 23 reaches the end of its stroke, the position sensor located at the end of the detection plate linear actuator 23 returns a trigger signal. Based on this feedback signal, the main controller controls the microcontroller to select supercapacitors 4 at different positions using a matrix scanning method. The detector 26 reads the electrical parameters of the supercapacitors 4 and transmits these parameters to the main controller. The main controller determines and classifies the electrical parameters of the supercapacitors 4 at each position and generates an information matrix containing the position information and the determination results.

[0042] S4: After the test is complete, the main controller issues a command to the I / O controller, controlling the first solenoid valve to switch the air path, causing the test plate 22 to rise along with the test plate linear actuator 23. When the test plate 22 reaches its starting point, the position sensor at the starting point of the test plate linear actuator 23 generates a trigger signal. Based on this feedback signal, the main controller issues a command to the I / O controller, controlling the second solenoid valve to switch the air path, causing the test platform 24 to continue moving rightward along with the platform linear actuator 25.

[0043] S5: When the inspection platform 24 moves right to the suction position, the position sensor at that position generates a trigger signal. Based on this signal, the main controller switches the air path of the third solenoid valve, causing the suction plate 31 to press downward along with the vertical linear actuator 32. When the vertical linear actuator 32 reaches the end of its stroke, the position sensor at the end of its stroke generates a trigger signal. Based on this signal, the main controller switches the air paths of all fifth solenoid valves, energizing the vacuum cups 311 and securing all super electrodes 4.

[0044] S6: After adsorption is complete, the main controller sends a command to the I / O controller, controlling the third solenoid valve to switch the air path. This causes the suction plate 31 to move upward along with the vertical linear actuator 32. When the vertical linear actuator 32 reaches the starting point of its stroke, the position sensor at that location returns a trigger signal. Based on this feedback signal, the main controller controls the fourth solenoid valve to switch the air path, causing the suction plate 31 to move rightward along with the horizontal linear actuator 33.

[0045] S7: When the horizontal linear actuator 33 moves right to the designated position 2, the position sensor at designated position 2 responds with a trigger signal. Based on this feedback signal and the information matrix, the main controller determines whether there is a supercapacitor 4 at that position that needs to be released (i.e., whether there is a supercapacitor 4 that meets the numerical conditions for that position). If not, the main controller controls the suction plate 31 to continue moving rightward with the horizontal linear actuator 33. If so, the main controller controls the suction plate 31 to stop moving with the horizontal linear actuator 33. Simultaneously, the fifth solenoid valve corresponding to all supercapacitors 4 that meet the numerical conditions for that position is switched, connecting the vacuum suction cup 311 to the atmosphere and releasing the corresponding supercapacitors 4. The released supercapacitors 4 naturally fall into the funnel 34 directly below the designated position 2 and ultimately enter the collection bin 35. Once all supercapacitors 4 that meet the numerical conditions for the designated position 2 have been released, the main controller controls the fourth solenoid valve to switch the air path, causing the suction plate 31 to continue moving rightward with the horizontal linear actuator 33.

[0046] S8: Repeat the above S7 until all supercapacitors 4 are released.

[0047] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not depart from the present invention should be included in the patent scope of this case.
