Description

Technical Field

[0001] The present invention belongs to the technical field of lithium capacitor resistance detection, and more specifically, relates to a lithium capacitor SOC detection device. Background Art

[0002] Lithium-ion capacitors are a new type of energy storage element between supercapacitors and lithium-ion batteries. In terms of structure, they combine the positive electrode material of double-layer capacitors with the negative electrode material having lithium-ion insertion / extraction redox behavior. They possess the characteristics of both supercapacitors and lithium-ion batteries, with advantages such as high energy density, high power density, low self-discharge, and long cycle life. In the performance evaluation of electronic components and energy storage devices, the measurement of resistance is a key technology that directly affects the efficiency, lifespan, and safety of the devices. Traditional resistance measurement methods are mainly based on Ohm's law (R = V / I), that is, by applying a known current and measuring the voltage drop to calculate the resistance value. Among them, the pulse discharge method is used for dynamic internal resistance measurement. By applying a short-term large current pulse and recording the voltage transient response, it is closer to the internal resistance value under the actual working state. When detecting lithium-ion capacitors, the pins on the lithium-ion capacitors are usually electrically connected to the clips on the detection device. However, this method is obviously too inefficient for batch detection of the resistance of lithium-ion capacitors. In addition, when some automated devices perform automated detection, the pins on the lithium-ion capacitors are prone to being skewed when inserted into the detection sockets, making it impossible to conduct power-on detection. For this reason, a lithium capacitor SOC detection device is proposed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a lithium capacitor SOC detection device that can overcome or at least partially solve the above problems.

In the initial state, the clamping arms, the installation block, and the positioning seats are in a horizontal state; rotating the installation block drives the clamping arms to move to both sides of the lithium capacitor located in the positioning groove; driving the installation block to move downward close to the positioning seat, the two clamping blocks clamp the lithium capacitor, and when the installation block moves downward, the lithium capacitor is pushed down to the detection position through spring four; when the installation block moves upward and resets, the clamping arms pull the lithium capacitor out of the positioning seat, and when the installation block resets and rotates in reverse, the lithium capacitor is unloaded.

[0005] Preferably, guide posts are fixedly connected to both sides of the positioning seat. An installation plate is slidably connected to the guide posts. Slide frames are symmetrically and fixedly connected to the installation plate. The slide frames are slidably connected to the guide posts. A second spring is connected between the slide frames and the positioning seat. The installation block is rotatably connected to the installation plate through a torsion spring.

[0006] Further, guide rods are fixedly connected to both sides of the installation block. Slot openings and sliding grooves are respectively formed in the guide posts. The guide rods slide in the sliding grooves.

[0007] Preferably, a sliding sleeve is fixedly connected in the installation block. A sliding rod is slidably connected to the sliding sleeve. A fourth spring is connected between the end of the sliding rod and the sliding sleeve.

[0008] Preferably, guiding grooves are symmetrically formed in the installation block. Convex blocks are fixedly connected to both sides of the top end of the clamping arm. The convex blocks are located in the guiding grooves. Second magnetic blocks are symmetrically installed on the bottom surface of the installation plate. A connecting block is installed on one side of the top end of the clamping arm. A first magnetic block is installed on the connecting block. The first magnetic block and the second magnetic block are attracted to each other.

[0009] Preferably, a connecting rod is slidably connected between the two clamping arms. The connecting rod is perpendicular to the two clamping arms. A third spring is sleeved on the connecting rod.

[0010] Preferably, an electromagnet one is installed on the installation plate. An electromagnet two is installed on the positioning seat.

[0011] Further, L-shaped grooves are symmetrically formed in the positioning seat. A resisting block is slidably connected in the L-shaped grooves. A first spring is connected to the resisting block. A vertical rod is slidably connected in the L-shaped grooves. The vertical rod is connected to the first spring. The vertical rod corresponds to the end of the clamping arm. The resisting block corresponds to the wiring socket slot.

[0012] Preferably, a pushing member is rotatably arranged above the guide posts. A support rod is installed on the installation block. A collar is installed on the execution end of the pushing member. The collar is rotatably connected to the support rod.

[0013] A detection method for a lithium capacitor SOC detection device includes the following steps: S1. Lithium capacitor feeding: Vertically insert the lithium capacitor into the positioning groove of the positioning seat of the turntable, aligning the pins with the wiring socket slot; S2. Automatic clamping and flipping: Drive the installation block to flip downward, driving the symmetric clamping arms to move to both sides of the lithium capacitor. The clamping blocks at the ends of the clamping arms clamp the lithium capacitor. At the same time, limit through the guide rods and the sliding grooves to prevent deviation; S3. Axial pressing and electrical contact: The installation block continues to move downward, applying a vertically downward pressure to the lithium capacitor through the fourth spring to ensure that the pins are fully inserted into the wiring socket slot; S4, resistance detection: apply detection current to the lithium capacitor through the wiring slot, measure its voltage response, and calculate the equivalent resistance or SOC state; S5, classified unloading and resetting: After the detection is completed, electromagnet 1 and electromagnet 2 are powered off, spring 2 pushes the mounting plate upward, the clamp arm maintains the clamping state to pull out the lithium capacitor, the mounting block is reset and reversed, and the unloading of the lithium capacitor is completed.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. The lithium capacitor SOC detection device can automatically clamp the lithium capacitor by flipping the mounting block when performing resistance detection on the lithium capacitor, and after clamping, a downward thrust coaxial with the lithium capacitor is applied to the lithium capacitor from above, so that the lithium capacitor is completely inserted vertically downward into the wiring slot. By first clamping and limiting the lithium capacitor and then pushing down the lithium capacitor, the pins of the lithium capacitor are effectively prevented from being skewed in the wiring slot.

[0015] 2. The lithium capacitor SOC detection device can not only clamp the lithium capacitor and then push it down to the detection position before detecting the lithium capacitor to avoid the pins of the lithium capacitor from being skewed, but also automatically pull the lithium capacitor out of the positioning seat and flip it over when the mounting plate is moved up after the detection is completed. While completing the separation from the positioning seat, the lithium capacitor is closer to the outer edge of the turntable, making it convenient to take the lithium capacitor after the detection.

[0016] 3. The lithium capacitor SOC detection device can also change the unloading method after the lithium capacitor is detected according to actual needs. The unloading method includes controlling the position of the protrusion on the clamping arm in the guide groove, and then controlling whether the two clamping arms need to release the clamping of the lithium capacitor when the mounting block moves up and reverses, thereby meeting the unloading methods with different needs.

[0017] 4. In the lithium capacitor SOC detection device, when the end of the clamp arm contacts the positioning seat and approaches each other, the clamp arm will push the vertical rod to slide in the L-shaped groove during the process of approaching each other, and during the sliding process, the spring will push the contact block to contact the pin, so that the pin and the wiring slot are in close contact, avoiding the wiring slot from loosening due to frequent testing, which will cause the pin to be unable to be electrically connected to the wiring slot.

Detailed implementation manners

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0021] Embodiment 1: Refer to Figures 1-11, A lithium capacitor SOC detection device, including a turntable 1 rotatably arranged, and further including: a plurality of positioning seats 11 circumferentially arranged on the turntable 1, and positioning grooves 111 and wiring slots 114 are respectively opened on the positioning seats 11; an installation block 13 rotatably arranged through a torsion spring, clamping arms 132 are symmetrically connected to the installation block 13, clamping blocks 134 are installed on the clamping arms 132, and in the initial state, the clamping arms 132, the installation block 13 and the positioning seat 11 are in a horizontal state; rotating the installation block 13 drives the clamping arms 132 to move to both sides of the lithium capacitor 112 located in the positioning groove 111; driving the installation block 13 to move downward close to the positioning seat 11, the two clamping blocks 134 clamp the lithium capacitor 112, and when the installation block 13 moves downward, the lithium capacitor 112 is pushed down to the detection position through the spring four 142; when the installation block 13 moves upward and resets, the clamping arms 132 pull out the lithium capacitor 112 from the positioning seat 11, and when the installation block 13 resets and reverses, the lithium capacitor 112 is unloaded.

[0022] Guide columns 12 are fixedly connected to both sides of the positioning seat 11, a mounting plate 121 is slidably connected to the guide columns 12, sliding frames 123 are symmetrically and fixedly connected to the mounting plate 121, the sliding frames 123 are slidably connected to the guide columns 12, a spring two 122 is connected between the sliding frames 123 and the positioning seat 11, and the installation block 13 is rotatably connected to the mounting plate 121 through a torsion spring.

[0023] A sliding sleeve 14 is fixedly connected in the installation block 13, a sliding rod 141 is slidably connected to the sliding sleeve 14, and a spring four 142 is connected between the end of the sliding rod 141 and the sliding sleeve 14.

[0024] When this device is in use, the turntable 1 is rotatably arranged on the workbench 10, a motor for driving the rotation of the turntable 1 is installed on the workbench 10, the motor drives the turntable 1 to rotate intermittently, and the number of positioning seats 11 on the turntable 1 can be installed according to the actual production situation. In this embodiment, the number of positioning seats 11 on the turntable 1 is six; among them, when the number of positioning seats 11 increases, the diameter of the corresponding turntable 1 also needs to be increased to avoid the distance between adjacent positioning seats 11 being too close; Without external interference, the initial state of the installation block 13 is horizontal with the positioning seat 11 (refer to Figure 4 ), which makes the positioning groove 111 on the positioning seat 11 in an open state, facilitating the insertion of the lithium capacitor 112 into the positioning groove 111; When the turntable 1 pauses rotating, insert the pin 113 of the lithium capacitor 112 into the wiring slot 114 of the positioning seat 11. Then drive the mounting block 13 to turn downward on the mounting plate 121. After turning, the two clamping arms 132 will be located on both sides of the lithium capacitor 112 respectively. When driving the mounting plate 121 to move downward, the two clamping arms 132 will move closer to the lithium capacitor 112 and clamp the lithium capacitor 112 through the clamping blocks 134. When the mounting plate 121 moves downward, the ends of the clamping arms 132 will abut against the positioning seat 11. At this time, the mounting block 13 will continue to move downward and approach the lithium capacitor 112 through the spring four 142, pressing the lithium capacitor 112 tightly against the positioning groove 111, so that the pin 113 is completely inserted into the wiring slot 114, and the lithium capacitor 112 completely enters the detection position and waits for resistance detection; Therefore, when the device performs resistance detection on the lithium capacitor 112, by turning the mounting block 13, it can automatically clamp the lithium capacitor 112, and after clamping, apply a downward thrust coaxial with the lithium capacitor 112 to the lithium capacitor 112 from above, so that the lithium capacitor 112 is vertically inserted into the wiring slot 114 completely downward. By first clamping and limiting the lithium capacitor 112 and then pushing the lithium capacitor 112 downward, it effectively avoids the pin 113 of the lithium capacitor 112 from being skewed in the wiring slot 114.

[0025] Apply current to the lithium capacitor 112 through the wiring slot 114 and perform resistance measurement; secondly, by setting the rotating turntable 1, the device can quickly perform batch resistance detection on the lithium capacitor 112, effectively improving the detection efficiency.

[0026] Embodiment 2: Refer to Figure 9 、 Figure 10 、 Figure 11 A lithium capacitor SOC detection device is basically the same as that in Embodiment 1. Further: Guide rods 130 are fixedly connected to both sides of the mounting block 13, and slot openings 124 and sliding grooves 125 are respectively formed on the guide posts 12, and the guide rods 130 slide in the sliding grooves 125.

[0027] Guiding grooves 131 are symmetrically formed in the mounting block 13. Convex blocks 133 are fixedly connected to both sides of the top of the clamping arm 132, and the convex blocks 133 are located in the guiding grooves 131. Magnetic blocks two 136 are symmetrically mounted on the bottom surface of the mounting plate 121. A connecting block 135 is mounted on one side of the top of the clamping arm 132, and a magnetic block one 1351 is mounted on the connecting block 135, and the magnetic block one 1351 and the magnetic block two 136 are attracted to each other.

[0028] A connecting rod 137 is slidably connected between the two clamping arms 132. The connecting rod 137 is perpendicular to the two clamping arms 132, and a spring three 138 is sleeved on the connecting rod 137.

[0029] An electromagnet one 15 is installed on the mounting plate 121, and an electromagnet two 151 is installed on the positioning seat 11; When driving the mounting block 13 to turn downward, the guide rod 130 will enter the chute 125 through the slotted opening 124. The chute 125 is vertically formed on the guide post 12. When the mounting plate 121 moves downward, the guide rod 130 slides in the chute 125 to limit the position of the mounting block 13 after flipping, effectively preventing the mounting block 13 from reversing due to the resilience of the torsion spring; When the guide rod 130 enters the chute 125 and the mounting block 13 moves downward, the carriage 123 presses the spring two 122, and the spring two 122 starts to store energy; When the mounting block 13 moves downward, the end of the clamping arm 132 abuts against the positioning seat 11. The clamping arm 132 makes the convex block 133 move from the reset groove 1311 to the inclined groove 1312 through the cooperation of the convex block 133 and the guiding groove 131. During this process, the two clamping arms 132 approach each other to realize the automatic clamping and limiting function of the lithium capacitor 112, and the magnet one 1351 on the clamping block 134 is adsorbed to the magnet two 136 on the mounting plate 121. It should be understood that a soft pad is provided on the inner wall surface of the clamping block 134 to protect the lithium capacitor 112; Subsequently, during the continuous downward movement of the mounting block 13, the end of the spring four 142 contacts the lithium capacitor 112 and presses and pushes the lithium capacitor 112, so that the lithium capacitor 112 completely enters the detection position in the positioning groove 111; Subsequently, the electromagnet one 15 and the electromagnet two 151 are adsorbed to each other, and the mounting plate 121 stops moving downward; When the detection is completed, the electromagnet one 15 and the electromagnet two 151 are powered off, and the spring two 122 pushes the mounting plate 121 to move upward and reset. Since the two clamping arms 132 are connected to the mounting plate 121 through the magnet one 1351, when the mounting plate 121 moves upward, the two clamping arms 132 will always hold the lithium capacitor 112. Secondly, when the mounting plate 121 moves upward, the mounting block 13 is limited by the chute 125 and also maintains the flipped state, that is, the clamping arm 132 is perpendicular to the positioning seat 11. When the guide rod 130 on the mounting block 13 reaches the slotted opening 124, the mounting block 13 reverses and resets under the drive of the torsion spring, and drives the lithium capacitor 112 to flip through the clamping arm 132. Therefore, this device can not only clamp the lithium capacitor 112 first and then push it down to the detection position before detecting the lithium capacitor 112 to avoid the pins 113 of the lithium capacitor 112 from being skewed, but also can automatically pull out the lithium capacitor 112 from the positioning seat 11 and flip it 90 degrees when the mounting plate 121 moves upward after the detection is completed. While completing the separation from the positioning seat 11, the lithium capacitor 112 is made closer to the outer periphery of the turntable 1, facilitating the taking of the detected lithium capacitor 112.

[0030] In one embodiment, by controlling the position of the bump 133 on the clamping arm 132 in the guiding groove 131, it is further controlled whether the two clamping arms 132 need to release the clamping of the lithium capacitor 112 when the mounting block 13 moves upward and reverses; When it is not necessary for the clamping arm 132 to release the clamping of the lithium capacitor 112, by changing the distance between the first electromagnet 15 and the second electromagnet 151 and the distance between the first magnetic block 1351 and the second magnetic block 136 to the required position (the height of the first electromagnet 15 on the mounting plate 121 is adjustable, and the adjustment method can be to adjust the position of the screw hole between the first electromagnet 15 and the mounting plate 121 and connect them by tightening bolts; the first magnetic block 1351 is fixed by changing the position of the connecting block 135 on the clamping arm 132 and tightening the screws), when the mounting block 13 moves downward, the bump 133 on the clamping arm 132 enters the vertical groove 1313 of the guiding groove 131, the first electromagnet 15 and the second electromagnet 151 are attracted to each other, and the first magnetic block 1351 and the second magnetic block 136 are attracted to each other. When the mounting block 13 moves upward, due to the horizontal thrust generated by the third spring 138 on the two clamping arms 132 and the attraction between the first magnetic block 1351 and the second magnetic block 136, the bump 133 on the clamping arm 132 abuts against the inner wall of the vertical groove 1313, and the third spring 138 cannot push the two clamping arms 132 apart. That is, after the mounting block 13 moves upward and reverses, the two clamping arms 132 will not release the clamping of the lithium capacitor 112. At this time, manual blanking or mechanical gripper blanking can be used. When manually removing the lithium capacitor 112, only by pulling the lithium capacitor 112 away from the mounting block 13, the two clamping arms 132 can be automatically separated from the lithium capacitor 112, which is convenient and fast to remove the lithium capacitor 112.

[0031] In another embodiment, when it is necessary for the clamping arm 132 to release the clamping of the lithium capacitor 112 after the mounting block 13 reverses upward, by changing the distance between the first electromagnet 15 and the second electromagnet 151 and the distance between the first magnetic block 1351 and the second magnetic block 136 to the required position (the height of the first electromagnet 15 on the mounting plate 121 is adjustable, and the adjustment method can be to adjust the position of the screw hole between the first electromagnet 15 and the mounting plate 121 and connect them by tightening bolts; the first magnetic block 1351 is fixed by changing the position of the connecting block 135 on the clamping arm 132 and tightening the screws), when the mounting block 13 moves downward, the bump 133 on the clamping arm 132 only moves to the junction of the inclined groove 1312 and the vertical groove 1313, the first electromagnet 15 is attracted to the second electromagnet 151, and the first magnetic block 1351 and the second magnetic block 136 are attracted to each other, and the downward movement of the mounting plate 121 is stopped; When the mounting block 13 moves upward and reverses, the first magnetic block 1351 and the second magnetic block 136 are separated due to the reversal of the mounting block 13. At this time, the two clamping arms 132 move away from each other under the push of the third spring 138, thereby realizing the function of releasing the lithium capacitor 112 after the mounting block 13 reverses; Furthermore, a material guide plate is arranged outside the workbench 10, and one end of the material guide plate is close to the turntable 1. At least two material guide plates are arranged, one is a qualified product unloading area, and the other is an unqualified product unloading area. When the lithium capacitor 112 is qualified or unqualified, after reaching the corresponding material guide plate, the electromagnet 15 and the electromagnet 2 151 are powered off, the mounting plate 121 moves up and pulls out the lithium capacitor 112, and after the mounting block 13 is reversed, the lithium capacitor 112 falls on the material guide plate, completing the collection after detection; it should be understood that soft objects are arranged on the material guide plate to prevent the lithium capacitor 112 from falling and being damaged by bumps.

[0032] Therefore, the device can selectively change according to the actual material discharging method after detecting the lithium capacitor 112, thereby meeting different material discharging needs.

[0033] Example 3: Reference Figure 8 , Figure 9 , a lithium capacitor SOC detection device, which is basically the same as Example 2, and further: an L-shaped groove 115 is symmetrically opened in the positioning seat 11, a resistance block 118 is slidably connected in the L-shaped groove 115, a spring 117 is connected to the resistance block 118, a vertical rod 116 is slidably connected in the L-shaped groove 115, the vertical rod 116 is connected to the spring 117, the vertical rod 116 corresponds to the end of the clamp arm 132, and the resistance block 118 corresponds to the wiring slot 114; When the end of the clamping arm 132 contacts the positioning seat 11 and approaches each other, the clamping arm 132 will push the vertical rod 116 to slide in the L-shaped groove 115 during the process of approaching each other, and during the sliding process, the spring 117 will push the contact block 118 to contact the pin 113, so that the pin 113 and the wiring slot 114 are in close contact, thereby avoiding the wiring slot 114 from loosening due to frequent testing, which will cause the pin 113 to be unable to be electrically connected to the wiring slot 114.

[0034] It should be understood that the abutment block 118 is made of a non-conductive material, such as plastic.

[0035] Example 4: Reference Figure 6 , a lithium capacitor SOC detection device, which is basically the same as Example 3, and further includes: a pushing member 162 rotatably arranged above the guide column 12, a support rod 16 is installed on the mounting block 13, and a ring 161 is installed on the execution end of the pushing member 162, and the ring 161 is rotatably connected to the support rod 16.

[0036] A mounting frame is arranged on the turntable 1, and one end of the pusher 162 rotates on the mounting frame. By extending the execution end of the pusher 162, the mounting block 13 can be rotated and driven to flip downward, and the mounting block 13 can be moved up and reversed, thereby further improving the degree of automation.

[0037] In another embodiment, since it takes a certain amount of time to apply current to the lithium capacitor 112, the device can also be manually held by hand on the support rod 16, so that the mounting block 13 first flips and then is pulled downwards.

[0038] It should be noted that a limiting block for flipping the mounting block 13 downwards is provided on the mounting plate 121 to prevent the mounting block 13 from rotating excessively.

[0039] The pushing member 162 is a device capable of reciprocating linear motion such as a cylinder, a hydraulic rod, a lead screw, etc.; When the pushing member 162 is used to drive the mounting block 13 to flip, further, the top of the guide post 12 and the mounting plate 121 are electrically connected through the electromagnet three and the electromagnet four. After the execution end of the pushing member 162 extends to the set stroke and the mounting block 13 completes the downward flip, the electromagnet three and the electromagnet four are powered off, and the pushing member 162 continues to push the mounting block 13 downwards, avoiding the situation where the mounting block 13 directly moves downwards without flipping when the pushing member 162 pushes, increasing safety and ensuring the smooth operation of the device.

[0040] In this device, since the turntable 1 is rotatably arranged, existing rotary connectors are used to connect the circuits or air paths to avoid entanglement.

[0041] Example 5: Refer to Figures 1-8 , a detection method for a lithium capacitor SOC detection device, includes the following steps: S1. Feeding of the lithium capacitor 112: Vertically insert the lithium capacitor 112 into the positioning slot 111 of the positioning seat 11 of the turntable 1, with the pin 113 aligned with the wiring slot 114; S2. Automatic clamping and flipping: Drive the mounting block 13 to flip downwards, drive the symmetric clamping arms 132 to move to both sides of the lithium capacitor 112, and the clamping blocks 134 at the ends of the clamping arms 132 clamp the lithium capacitor 112. At the same time, it is limited by the guide rod 130 and the sliding groove 125 to prevent deviation; S3. Axial pressing and electrical contact: The mounting block 13 continues to move downwards, applying a vertically downward pressure to the lithium capacitor 112 through the spring four 142 to ensure that the pin 113 is completely inserted into the wiring slot 114; S4. Resistance detection: Apply a detection current to the lithium capacitor 112 through the wiring slot 114, measure its voltage response, and calculate the equivalent resistance or SOC state; S5. Classified discharging and resetting: After the detection is completed, the electromagnet one 15 and the electromagnet two 151 are powered off, the spring two 122 pushes the mounting plate 121 upwards, the clamping arms 132 keep the clamping state and pull out the lithium capacitor 112, and the mounting block 13 resets and reverses to complete the discharging of the lithium capacitor 112.
