Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and particularly relates to an automatic detection platform for the charge of energy storage batteries. Background Art

[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. There are two types: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The safety, specific capacity, self-discharge rate, and performance-price ratio of lithium batteries are all superior to those of lithium-ion batteries. After the battery production is completed, it is necessary to detect the battery charge to record the production qualification rate.

[0003] The existing detection of the charge of lithium batteries mostly involves manually placing the lithium batteries into the charge detection machine for detection. The operation speed is slow, the error rate is relatively high, resulting in inaccurate detection data. When a large number of batteries need to be detected, the work intensity is very high, requiring a large number of workers, which not only affects the detection results but also increases the cost. In addition, the structure of the lithium battery charge detection device in the related technology has the following deficiencies:

[0004] 1. Through manual detection, only one battery can be detected at a time, and batch detection of batteries cannot be achieved, resulting in low detection efficiency.

[0005] 2. It is impossible to accurately detect the charge of the battery, and the detection accuracy needs to be improved.

[0006] 3. Some devices need to manually grasp the battery for detection, with numerous steps, and workers are prone to fatigue, resulting in errors. Summary of the Invention

A clamping block is fixedly arranged on the top of each slider. A reset spring is fixedly arranged between one end of each sliding plate close to the traction rod and the bottom of the detection table.

[0013] Further, each power-on component includes a first wire and two power connection plates. The first wire is fixedly arranged on the top of the detection table. The two power connection plates are respectively fixedly arranged at both ends of the first wire.

[0014] Further, each test component includes a detection resistor, a coulomb meter, and a second wire. The coulomb meter is fixedly arranged on the top of the detection table. The second wire is fixedly arranged on the top of the detection table and is electrically connected to the coulomb meter.

[0019] Further, an avoidance groove for the rotation of six traction rods is formed on the top of the detection table.

[0020] Advantages of the present invention:

[0021] 1. By designing the detection table, the controller, the detection mechanism, the pressing mechanism, and three cushion blocks, workers only need to horizontally place multiple batteries on the tops of the three cushion blocks, and subsequent steps such as battery clamping, power-on, and detection are all automatically performed without the assistance of workers, reducing the labor efficiency of workers and at the same time avoiding misjudgment caused by worker fatigue.

[0022] 2. By designing a trapezoidal lapping groove on the top of the cushion block, the trapezoidal lapping groove has a structure with a wider top and a narrower bottom, so batteries of different sizes can be placed, thereby meeting the detection requirements of energy storage batteries of different sizes and improving the practicability and flexibility of this detection table.

[0023] 3. By designing the detection mechanism and the pressing mechanism, three batteries can be synchronously detected at a time. Compared with the prior art, it is not possible to only detect the charge of one battery at a time, and thus batch detection of the battery charge is realized, which is beneficial to improving the detection efficiency, expanding the production of batteries, and increasing the enterprise income.

[0024] 4. The present invention designs a test component, namely a detection resistor, a coulomb meter, and a second wire. After the two ends of the energy storage battery are powered on, since the first wire, the second wire, the coulomb meter, the detection resistor, and the two ends of the energy storage battery form a series circuit, when current flows through the resistor, the coulomb meter will generate an induction. By detecting the induction, the current flowing through the battery can be calculated. Therefore, the change in the power of the energy storage battery can be accurately tracked, and the accuracy can reach 1%. Furthermore, the data obtained by this detection platform is more accurate, scientific, and reasonable.

[0025] 5. The present invention designs a pressing mechanism and a buffer spring, which can ensure that the lifting plate descends evenly, preventing it from descending too fast and damaging the battery. During the detection, the tops of the three batteries are pressed tightly to prevent the batteries from falling due to unstable placement during the detection, ensuring the smooth progress of the detection work. The arc-shaped pressing rod can effectively fit the outer edge of the battery to ensure the pressing effect. The arc-shaped pressing rod is made of rubber and plastic material to ensure that the arc-shaped pressing rod is relatively insulated from the battery, preventing it from affecting the accuracy of the detection data.

Detailed implementation mode

[0036] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation modes.

[0037] Among them, the drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation of this patent; in order to better illustrate the embodiments of the present invention, some components in the drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product.

[0038] Referring to Figure 1 An automatic detection table 1 for the charge of an energy storage battery as shown, includes a detection table 1 and a controller 2. An installation chamber is provided at the bottom of the detection table 1. Two protective doors 10 are symmetrically arranged on the open end of the installation chamber. A handle is fixedly provided on the outer wall of each protective door 10. Four support feet are fixedly provided at the bottom of the detection table 1. The controller 2 is fixedly provided on the top of the detection table 1.

[0039] It further includes a detection mechanism 3 and a pressing mechanism 4. The pressing mechanism 4 is arranged on the top of the detection table 1 to fix the battery. The pressing mechanism 4 includes a lifting plate 40, a driving assembly 41 and three pressing assemblies 42. The driving assembly 41 is arranged on the top of the detection table 1. Two guide columns are symmetrically arranged on the top of the detection table 1. The lifting plate 40 is slidably arranged on the outer walls of the two guide columns through two linear bearings. The three pressing assemblies 42 are equidistantly arranged on the lifting plate 40. The detection mechanism 3 is arranged on the top of the detection table 1 to detect the charge of the battery. The detection mechanism 3 includes a telescopic assembly 30, three energizing assemblies 31 and three test assemblies 32. The telescopic assembly 30 is arranged at the bottom of the detection table 1. The three energizing assemblies 31 are equidistantly arranged on the top of the detection table 1. Each test assembly 32 is arranged beside an energizing assembly 31. The driving assembly 41, each energizing assembly 31 and each test assembly 32 are electrically connected to the controller 2.

[0040] In order to simultaneously adjust the positions of the three conical top blocks 302, a telescopic assembly 30 is designed. Refer to Figure 7 As shown, the telescopic assembly 30 includes a cylinder 300, a push plate 301, and three conical top blocks 302. The cylinder 300 is fixedly arranged at the bottom of the detection table 1. Two limit blocks are symmetrically arranged at the bottom of the detection table 1. Guide rods are inserted into the interior of each limit block. The push plate 301 is fixedly arranged at the output end of the cylinder 300. The push plate 301 is fixedly connected to the ends of the two guide rods. The three conical top blocks 302 are all fixedly arranged on the outer wall of the end of the push plate 301 away from the cylinder 300. The cylinder 300 is electrically connected to the controller 2. When the three energy storage batteries are all pressed tightly, the cylinder 300 is started through the controller 2, so that its output end extends out. Since its output end is fixedly connected to the push plate 301, the push plate 301 is slidably connected to the bottom of the detection table 1 through the two guide rods. Also, because the push plate 301 is fixedly connected to the three conical top blocks 302, the three conical top blocks 302 are driven to extend synchronously.

[0041] In order to ensure that the positive and negative electrodes of each energy storage battery are simultaneously energized and the three energy storage batteries are synchronously detected. Refer to Figure 3As shown, six slides 100 are arranged at equal intervals at the bottom of the test platform 1, and both ends of each conical top block 302 are in contact with the outer wall of one end adjacent to the two slides 100. Six slides 101 are fixedly arranged on the top of the test platform 1, and a traction rod 102 is hingedly arranged on the outer wall of each slide 100, and the traction rod 102 is hingedly arranged on the outer wall of one end of the slide 101. The top of each slide 101 is provided with an inclined groove 103, and a slider 104 is slidably arranged inside the inclined groove 103. The slider 104 The outer wall of the test bench 1 is fixed with an insertion rod 105, and each traction rod 102 is provided with a traction groove at one end away from the slide 100, and the insertion rod 105 is plugged into the traction groove. A clamping block 106 is fixed on the top of each slider 104, and a return spring 107 is fixed between the end of each slide 100 close to the traction rod 102 and the bottom of the test bench 1. The clamping block 106 is used to plug the first wire 310, which plays a role of limiting and supporting. When the conical top block 302 extends toward the two slides 100 When the adjacent ends are close to each other, since both ends of each conical top block 302 are in contact with the outer wall of the adjacent end of the two slides 100, the two slides 100 slide towards each other when they are resisted by the outer walls of the two ends of the conical top block 302. The two return springs 107 play a buffering role to ensure that the two slides 100 approach the positive and negative poles of the battery at a uniform speed, thereby driving the two traction rods 102 to rotate inward. Under the influence of the hinge point between the traction rod 102 and the slide 101, the avoidance groove is in contact with the insertion rod 101 inside. 05, because the bottom of the slider 104 is inclined, it just fits on the top of the inclined groove 103 to slide, thereby driving the blocks 106 on the top of the two sliders 104 to slide toward each other, and further driving the two power connection plates 311 to slide toward each other and fit on the positive and negative poles of the energy storage battery. When the battery detection is completed, the conical top block 302 shrinks, and the two return springs 107 pull the two slides 100 to slide back to each other, thereby loosening the two power connection plates 311, making it convenient for workers to remove the battery.

[0042] In order to energize the two ends of the energy storage battery, three power supply components 31 are designed. Figure 4 As shown, each power-on component 31 includes a first wire 310 and two power connection plates 311. The first wire 310 is fixed on the top of the test bench 1, and the two power connection plates 311 are respectively fixed at both ends of the first wire 310. When the two power connection plates 311 are respectively attached to the positive and negative poles of the energy storage battery, the controller 2 is started to energize the first wire 310, thereby energizing the two ends of the energy storage battery.

[0043] In order to ensure accurate detection of the charge level of the energy storage battery, three test components 32 are designed, referring to Figure 4As shown, each test component 32 includes a detection resistor 320, a coulomb meter 321, and a second wire 322. The coulomb meter is fixedly arranged on the top of the detection table 1, and the second wire 322 is fixedly arranged on the top of the detection table 1 and electrically connected to the coulomb meter. The detection resistor 320 is fixedly arranged between the first wire 310 and the second wire 322 through two pads. The coulomb meter is electrically connected to the controller 2. When both ends of the energy storage battery are powered on, since the first wire 310, the second wire 322, the coulomb meter, the detection resistor 320, and both ends of the energy storage battery form a series circuit, when current flows through the resistor, the coulomb meter will generate an induction. By detecting the induction, the current flowing through the battery can be calculated. Therefore, the change in the power of the energy storage battery can be accurately tracked, and the accuracy can reach 1%. Furthermore, the data obtained by the detection table 1 is more accurate, scientific, and reasonable.

[0044] In order to drive the lifting plate 40 to lift smoothly and evenly and prevent the battery from being crushed, a driving component 41 is designed. Refer to Figure 5 As shown, the driving component 41 includes a servo motor 410, a first connecting rod 411, and a second connecting rod 412. The servo motor 410 is fixedly arranged on the top of the detection table 1, the first connecting rod 411 is sleeved on its output end, the second connecting rod 412 is hinged at one end of the first connecting rod 411 away from the servo motor 410, and the first connecting rod 411 is shorter than the second connecting rod 412. The end of the second connecting rod 412 away from the first connecting rod 411 is hinged to the bottom of the lifting plate 40. The servo motor 410 is electrically connected to the controller 2. When three energy storage batteries are respectively placed on the tops of the three placing blocks 112, the servo motor 410 is started through the controller 2. Since its output end is fixedly connected to the first connecting rod 411, the first connecting rod 411 is driven to rotate. Also, because one end of the first connecting rod 411 away from the servo motor 410 and the bottom of the lifting plate 40 are respectively hinged to both ends of the second connecting rod 412, and in addition, the lifting plate 40 is slidably connected to two guide posts, the lifting plate 40 is driven to descend between the two guide posts. The output end of the servo motor 410 cannot rotate when powered off compared with an ordinary motor. Therefore, it can be ensured that the lifting plate 40 will not rise after descending in place, ensuring the accuracy of the descent.

[0045] In order to synchronously press the three energy storage batteries and ensure the detection stability, three pressing components 42 are designed. Refer to Figure 2As shown, each pressing component 42 includes a mounting plate 420, a connecting rod 421, a cross bar 422, and two arc-shaped pressing rods 423. The mounting plate 420 is fixedly arranged at the bottom of the lifting plate 40. The connecting rod 421 is fixedly arranged at one end of the bottom of the mounting plate 420 away from the lifting plate 40. The cross bar 422 is fixedly arranged at the bottom of the connecting rod 421. The two arc-shaped pressing rods 423 are symmetrically arranged at both ends of the cross bar 422. Each arc-shaped pressing rod 423 is made of rubber and plastic material. When the lifting plate 40 descends between the two guide posts, since the mounting plate 420 is fixedly connected to the bottom of the lifting plate 40, the cross bar 422 and the mounting plate 420 are respectively fixedly connected to both ends of the connecting rod 421, and because the two arc-shaped pressing rods 423 are respectively fixedly connected to both ends of the cross bar 422, the two arc-shaped pressing rods 423 are driven to descend, pressing the outer wall of the energy storage battery to prevent the battery from falling due to unstable placement during detection and ensuring the smooth progress of the detection work. The arc-shaped pressing rod 423 can effectively fit the outer edge of the battery to ensure the pressing effect. And the arc-shaped pressing rod 423 is made of rubber and plastic material to ensure that the arc-shaped pressing rod 423 is relatively insulated from the battery and prevent the influence on the accuracy of the detection data.

[0046] To ensure the smooth descent of the six arc-shaped pressing rods 423, maintain a reasonable pressing force and speed, refer to Figure 2 As shown, a retaining post 11 is fixedly arranged at the top of each guide post. A limiting ring 110 is fixedly arranged on the outer wall of the lower half of each guide post. A buffer spring 111 is arranged between the top of the limiting ring 110 and the bottom of the linear bearing. The buffer spring 111 is sleeved on the outer wall of the guide post. The buffer spring 111 can ensure the uniform descent of the lifting plate 40, prevent it from descending too fast and causing damage to the battery, and thus is beneficial to improving the detection quality.

[0047] To realize the batch detection of the charged amount of the energy storage battery and improve the detection efficiency, refer to Figure 4 As shown, three placing blocks 112 are equidistantly arranged at the top of the detection table 1. Each placing block 112 is located below a pressing component 42. A trapezoidal lapping groove 113 is opened at the top of each placing block 112. Every two clamping blocks 106 are located at both ends of a placing block 112. When detecting the charged amount of the energy storage battery, first place the three energy storage batteries on the tops of the three placing blocks 112 respectively. The trapezoidal lapping groove 113 has a structure with a wider top and a narrower bottom, so batteries of different sizes can be placed, thus meeting the detection requirements of energy storage batteries of different sizes and improving the practicability and flexibility of this detection table 1.

[0048] To ensure that the traction rod 102 is not blocked by the detection table 1 when rotating, an avoidance groove for the six traction rods 102 to rotate is opened at the top of the detection table 1. When the traction rod 102 rotates, the avoidance groove plays an avoidance role and provides a rotation space for it.

[0049] Working principle of the present invention: When measuring the charge level of the energy storage batteries, first place the three energy storage batteries on the tops of the three placement blocks 112 respectively. The trapezoidal overlapping groove 113 has a structure with a wider upper part and a narrower lower part, so batteries of different sizes can be placed, thereby meeting the detection requirements for energy storage batteries of different sizes and improving the practicability and flexibility of the present detection platform 1.

[0050] After the three energy storage batteries are respectively placed on the tops of the three placement blocks 112, start the servo motor 410 through the controller 2. Since its output end is fixedly connected to the first connecting rod 411, the first connecting rod 411 is driven to rotate. Also, since one end of the first connecting rod 411 away from the servo motor 410 and the bottom of the lifting plate 40 are respectively hinged to both ends of the second connecting rod 412, and in addition, the lifting plate 40 is slidably connected to the two guide posts, the lifting plate 40 is driven to descend between the two guide posts. The output end of the servo motor 410 cannot rotate when powered off compared to a normal motor, so it can ensure that the lifting plate 40 will not rise after descending in place, ensuring the accuracy of the descent.

[0051] When the lifting plate 40 descends between the two guide posts, since the mounting plate 420 is fixedly connected to the bottom of the lifting plate 40, the cross bar 422 and the mounting plate 420 are respectively fixedly connected to both ends of the connecting rod 421, and also, since the two arc-shaped pressing rods 423 are respectively fixedly connected to both ends of the cross bar 422, the two arc-shaped pressing rods 423 are driven to descend, pressing the outer walls of the energy storage batteries to prevent the batteries from falling due to unstable placement during detection and ensuring the smooth progress of the detection work. The arc-shaped pressing rods 423 can effectively fit the outer edge of the battery to ensure the pressing effect. The arc-shaped pressing rods 423 are made of rubber and plastic material to ensure that the arc-shaped pressing rods 423 are relatively insulated from the battery, preventing the influence on the accuracy of the detection data. The buffer spring 111 can ensure that the lifting plate 40 descends at a uniform speed, preventing it from descending too fast and causing damage to the battery, which is beneficial to improving the detection quality.

[0052] After the three energy storage batteries are all pressed tightly, start the cylinder 300 through the controller 2, so that its output end extends. Since its output end is fixedly connected to the push plate 301, the push plate 301 is slidably connected to the bottom of the detection platform 1 through two guide rods, and also, since the push plate 301 is fixedly connected to the three conical top blocks 302, the three conical top blocks 302 are driven to extend synchronously.

[0053] The clamping block 106 is used to plug the first wire 310, and plays a role of limiting and supporting. When the conical top block 302 extends to approach the adjacent end of the two slides 100, since both ends of each conical top block 302 are in contact with the outer wall of the adjacent end of the two slides 100, the two slides 100 slide towards each other when they are resisted by the outer walls of the two ends of the conical top block 302. The two return springs 107 play a buffering role, ensuring that the two slides 100 approach the positive and negative poles of the battery at a uniform speed, thereby driving the two traction rods 102 to rotate inward. Under the influence of the hinge point of the platform 101, the avoidance groove resists the plug rod 105 inside it. Since the bottom of the slider 104 is inclined, it just fits on the top of the inclined groove 103 and slides, thereby driving the blocks 106 on the top of the two sliders 104 to slide toward each other, and further driving the two power connection plates 311 to slide toward each other and fit on the positive and negative poles of the energy storage battery. When the battery detection is completed, the conical top block 302 shrinks, and the two return springs 107 pull the two slides 100 to slide back to back, thereby loosening the two power connection plates 311, making it convenient for workers to remove the battery.

[0054] When the two power connection plates 311 are respectively attached to the positive and negative electrodes of the energy storage battery, the controller 2 is started to energize the first wire 310, thereby energizing the two ends of the energy storage battery. Since the first wire 310, the second wire 322, the coulomb meter, the detection resistor 320 and the two ends of the energy storage battery form a series circuit, when current flows through the resistor, the coulomb meter will generate induction, and the current flowing through the battery can be calculated by detecting the induction. Therefore, the change of the power of the energy storage battery can be accurately tracked, and the accuracy can reach 1%, thereby making the data obtained by the present detection station 1 more accurate, scientific and reasonable.
