Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to automatic detection equipment for energy storage batteries. Background Art

[0002] In the energy storage battery production line, the finished batteries also need to undergo sealing tests, pressure tests, leak tests, etc.

[0003] The existing patent (application number: 202410910528.6) is a battery pressure detection device. This solution uses multiple clamping cylinders to clamp the battery, and then the central cylinder drives the clamping cylinder to rotate, and the fixed cylinder drives the detection plate to rotate, causing the battery to rotate, so that the clamping cylinder and the outer wall of the battery are always rotated and connected, thereby completing the detection operation of all areas of the outer wall of the battery. At the same time, the detection plate can also perform detection operations on the upper side of the battery. When electrolyte is precipitated on the upper side of the battery, since the electrolyte is a viscous liquid, it will hinder the rotation of the arc block. The arc block stretches the fourth spring, and the two second switch plates are against each other. When a bulge appears on the surface of the battery, the clamping cylinder will move toward the direction close to the circular rod. The clamping cylinder drives the detection rod to move through the arc plate. While the detection rod compresses the first spring, the two first switch plates are against each other. When the first switch plate or the second switch plate is activated, it means that the battery pressure test fails. However, this solution still has certain defects.

[0004] This solution can only detect cylindrical batteries and cannot operate on rectangular batteries. In addition, the detection plate only performs pressure detection on the upper side of the battery and cannot detect pressure detection on other parts of the battery. Similarly, the detection rod only detects bulges on the surface of the battery and cannot monitor the status of bulges in other parts of the battery, resulting in certain limitations in the use of this device.

Example

[0024] Reference Figures 1-12 , an energy storage battery automatic detection device, including the following structure: The placement box 1 is provided with a bottom plate 6 connected therein via an adjustment mechanism, the side walls of the bottom plate 6 are in contact with the inner wall of the placement box 1 , and an energy storage battery body 7 is provided on the bottom plate 6 .

[0025] The adjustment mechanism includes a cavity 2 opened in the placement box 1, four rectangular grooves 3 are opened on the top of the cavity 2, and rectangular rods 4 are sealed and slidably connected to the inner walls of the four rectangular grooves 3. The upper ends of the four rectangular rods 4 are fixedly connected to the lower end of the bottom plate 6, and the lower ends of the four rectangular rods 4 are elastically connected to the bottom of the cavity 2 through the first spring 5 (such as Figure 2 shown).

[0026] The reversing mechanism includes two first rods 8 and two second rods 9 (such as Figure 5 As shown), the side walls of the two first rods 8 are slidably connected to the upper side walls of the placement box 1, and the two first rods 8 are facing each other, the side walls of the two second rods 9 are slidably connected to the upper side walls of the placement box 1 away from the first rods 8, and the two second rods 9 are facing each other, and one end of the two first rods 8 and the two second rods 9 located in the placement box 1 is rotatably connected to a round rod 10 (combined with Figure 4 and Figure 5), the ends of the four round rods 10 close to each other are fixedly connected to the clamping plates 11, and the lower ends of the four clamping plates 11 are embedded with counterweight plates 12 to ensure that the four clamping plates 11 can be in a vertical state before the energy storage battery body 7 is clamped.

[0027] The reversing mechanism also includes two one-way bearings 13, wherein the inner ring side wall of one of the one-way bearings 13 is fixedly connected to the side wall of the round rod 10 close to one of the first rods 8, and the inner ring side wall of the other one-way bearing 13 is fixedly connected to the side wall of the round rod 10 close to one of the second rods 9. The outer ring side walls of the two one-way bearings 13 are fixedly connected to the gears 14 (combined with the gears 14). Figure 4 and Figure 5 ), the side walls of the first rod 8 and the second rod 9 close to the two one-way bearings 13 are fixedly connected to the first L-shaped plate 15, and the side walls of the two first L-shaped plates 15 are fixedly connected to the electric push rods 16. The movable end of the electric push rod 16 is fixedly connected to the tooth plate 17, and the tooth plate 17 engages with the gear 14 during the movement.

[0028] The lower side walls of the two first L-shaped plates 15 are fixedly connected to the oil pump frame 27, and the inner walls of the two oil pump frames 27 are sealed and slidably connected to the oil pump rod 28. The side wall of the output shaft of the electric push rod 16 is fixedly connected to the upper end of the oil pump rod 28 through the connecting plate 29. The inner walls of the two oil pump frames 27 are connected to the inner wall of the cavity 2 through the connecting pipe 30 (combined with the inner wall of the cavity 2). Figure 7 and Figure 8 ), hydraulic oil is provided in the cavity 2 and the two oil pump frames 27.

[0029] It should be noted that when the two clamping plates 11 fixedly connected to the two first rods 8 are facing the energy storage battery body 7, the two clamping plates 11 fixedly connected to the two second rods 9 are away from the energy storage battery body 7 (such as Figure 5 As shown); when the two splints 11 fixedly connected to the two second rods 9 are facing the energy storage battery body 7, the two splints 11 fixedly connected to the two first rods 8 are away from the energy storage battery body 7.

[0030] After the two clamping plates 11 fixedly connected to the two first rods 8 clamp the energy storage battery body 7, the electric push rod 16 corresponding to one of the first rods 8 is adjusted to extend, driving the tooth plate 17 to move in the direction close to the gear 14. At this time, the electric push rod 16 drives the oil pump rod 28 to move through the connecting plate 29, so that the space in the oil pump frame 27 at this location is increased, and then the oil pump frame 27 absorbs hydraulic oil from the cavity 2 through the connecting pipe 30, so that the hydraulic oil in the cavity 2 is reduced, and then the hydraulic oil in the four rectangular grooves 3 is reduced, and the four rectangular rods 4 are in Under the elastic force of the four first springs 5, the four rectangular rods 4 drive the bottom plate 6 to move downward, so that the bottom plate 6 is away from the lower end of the energy storage battery body 7. Then the tooth plate 17 moves to engage with the gear 14, and drives the gear 14 and the outer ring of the one-way bearing 13 to rotate forward. At this time, the outer ring of the one-way bearing 13 drives its inner ring to rotate, driving the round rod 10 to rotate forward, and then driving the energy storage battery body 7 to rotate, so that the energy storage battery body 7 can be refaced. At this time, the bottom plate 6 is away from the lower end of the energy storage battery body 7, and thus will not affect the rotation of the energy storage battery body 7; After the energy storage battery body 7 is changed, the electric push rod 16 is adjusted to contract, driving the tooth plate 17 to move in the direction away from the gear 14. At this time, the gear 14 and the outer ring of the one-way bearing 13 are driven to rotate in opposite directions. The outer ring of the one-way bearing 13 does not drive its inner ring to rotate, so that the position of the energy storage battery body 7 remains unchanged. As the electric push rod 16 contracts, the electric push rod 16 drives the oil pump rod 28 to move through the connecting plate 29, and squeezes the hydraulic oil in the oil pump frame 27 into the cavity 2 through the connecting pipe 30, thereby increasing the hydraulic oil in the cavity 2. At this time, the four rectangular rods 4 drive the bottom plate 6 to move upward under the action of the hydraulic oil, so that the upper end of the bottom plate 6 is in contact with the lower end of the energy storage battery body 7, ensuring the stability of the energy storage battery body 7 during the subsequent pressure detection of the energy storage battery body 7.

[0031] After the two clamping plates 11 fixedly connected to the two second rods 9 clamp the energy storage battery body 7, the electric push rod 16 corresponding to one of the second rods 9 is adjusted to extend, and then the above steps are repeated. The side of the energy storage battery body 7 can also be changed. In this way, the six sides of the rectangular energy storage battery body 7 can be pressure-tested, avoiding the problem that the prior art can only test cylindrical batteries and cannot operate on rectangular batteries. At the same time, the pressure test can only be performed on the upper side of the battery, and the pressure test cannot be performed on other positions of the battery.

[0032] The placement box 1 is provided with a moving mechanism for driving the two first rods 8 and the two second rods 9 to approach each other. The moving mechanism includes four third rods 18 fixedly connected to the lower end of the placement box 1. The side walls of the four third rods 18 are slidingly connected with the first plate 19 and the second plate 20. The side wall of the first plate 19 is rotatably connected to the side walls of the two first rods 8 away from each other through two fourth rods 21, and the side wall of the second plate 20 is rotatably connected to the side walls of the two second rods 9 away from each other through two fifth rods 22.

[0033] Four support seats 23 are fixedly connected to the lower end of the placement box 1. The side walls of the four support seats 23 located below the second plate 20 are commonly fixedly connected to the third plate 24. The lower end of the third plate 24 is fixedly connected to the motor 25. The movable end of the motor 25 is fixedly connected to the bidirectional screw 26. The side walls of the bidirectional screw 26 are threadedly connected to the side walls of the first plate 19 and the second plate 20.

[0034] The forward rotation of the motor 25 drives the bidirectional lead screw 26 to rotate forward, driving the first plate 19 and the second plate 20 to approach each other. At this time, the first plate 19 drives the two first rods 8 to approach each other through the two fourth rods 21, and the second plate 20 drives the two second rods 9 to move away from each other through the two fifth rods 22; the reverse rotation of the motor 25 drives the bidirectional lead screw 26 to rotate reversely, driving the first plate 19 and the second plate 20 to move away from each other. At this time, the first plate 19 drives the two first rods 8 to move away from each other through the two fourth rods 21, and the second plate 20 drives the two second rods 9 to approach each other through the two fifth rods 22.

[0035] The detection mechanism includes a fixed plate 36, a strip cavity 37 is opened in the fixed plate 36, a T-shaped plate 38 is slidably connected to the bottom of the strip cavity 37, and the side wall of the T-shaped plate 38 is rotatably connected to the detection wheel 40 through a cross rod 39.

[0036] The upper end of the third plate 24 is fixedly connected to the second L-shaped plate 31, and the upper end of the second L-shaped plate 31 is provided with a through slot 32. Two electric slide rails 33 are installed on the inner wall of the through slot 32. The side walls of the two electric slide rails 33 are jointly installed with a slider 34. The lower end of the slider 34 is fixedly connected to the cylinder 35, and the movable end of the cylinder 35 is fixedly connected to the upper end of the fixed plate 36.

[0037] A pressure plate 41 is slidably connected to the inner wall of the strip cavity 37 , and the upper end of the T-shaped plate 38 is elastically connected to the lower end of the pressure plate 41 via a plurality of second springs 42 . A pressure sensor 43 is installed at the top of the strip cavity 37 .

[0038] One side wall of the crossbar 39 passes through the side wall of the T-shaped plate 38 and is fixedly connected to a reflective sheet 45. The side wall of the T-shaped plate 38 is fixedly connected to a photoelectric speed sensor 44 through a bracket. The photoelectric speed sensor 44 and the pressure sensor 43 are both electrically connected to an external display device through wires.

[0039] It should be noted that the pressure sensor 43 can transmit the pressure signal it receives to an external display device through a wire to display the pressure size, and the photoelectric speed sensor 44 can convert the intensity or frequency of the photoelectric signal captured from the reflective sheet 45 into an electrical signal and then transmit it to an external display device through a wire to display the speed size. Its sensing methods are all existing technologies, so that the staff can judge whether there is a bulge on the surface of the energy storage battery body 7 based on whether the pressure displayed on the external display device increases. When the surface of the energy storage battery body 7 leaks, since the electrolyte is a viscous liquid, it will hinder the rotation of the detection wheel 40 and cause the speed of the cross bar 39 to decrease. At this time, the staff can judge whether the surface of the energy storage battery body 7 is leaking based on whether the speed displayed on the external display device decreases, and then the surface of the energy storage battery body 7 can be detected for bulges and leakage, thereby increasing the scope of use of the device.

[0040] When performing a pressure test, the adjustment cylinder 35 is extended to drive the fixed plate 36 and the detection wheel 40 to move downward. When the pressure of the detection wheel 40 on the surface of the energy storage battery body 7 reaches the test pressure, the cylinder 35 stops extending. At this time, the detection wheel 40 will drive the T-plate 38 to move upward. At this time, the T-plate 38 will drive the pressure plate 41 to move upward through multiple second springs 42 to squeeze the pressure sensor 43, so that the pressure sensor 43 senses a pressure signal and transmits it to the external display device through a wire to display the pressure. The pressure is the initial pressure size. When the detection wheel 40 encounters a bump during the subsequent rolling process, the detection wheel 40 will move upward, so that the squeezing force of the T-plate 38 on the pressure sensor 43 through the second spring 42 and the pressure plate 41 increases, and the pressure displayed on the external display device increases.

[0041] When performing pressure testing on the surface of the energy storage battery body 7, the energy storage battery body 7 is placed centered on the bottom plate 6, and then the motor 25 is adjusted to rotate forward, driving the bidirectional lead screw 26 to rotate forward, driving the first plate 19 and the second plate 20 to move closer to each other. At this time, the first plate 19 drives the two first rods 8 closer to each other through the two fourth rods 21, and the second plate 20 drives the two second rods 9 away from each other through the two fifth rods 22. Then, when the two clamping plates 11 fixedly connected to the two first rods 8 are against the energy storage battery body 7, the two clamping plates 11 fixedly connected to the two second rods 9 are away from the energy storage battery body 7. At this time, the upper surface of the energy storage battery body 7 is directly opposite to the detection wheel 40. The cylinder 35 is then adjusted to extend, driving the fixing plate 36 and the detection wheel 40 to move downward. When the pressure of the detection wheel 40 on the surface of the energy storage battery body 7 reaches the test pressure, the cylinder 35 stops extending. At this time, the detection wheel 40 drives the T-shaped plate 38 to move upward. At this time, the T-shaped plate 38 drives the pressure plate 41 upward through multiple second springs 42 to press the pressure sensor 43, so that the pressure sensor 43 senses a pressure signal and transmits it to an external display device through a wire to display the pressure. The pressure is the initial pressure. Then, the two electric slide rails 33 are driven to drive the fixed plate 36 to move back and forth on the upper surface of the energy storage battery body 7 through the slider 34 and the cylinder 35, so that the detection wheel 40 rolls and moves back and forth on the upper surface of the energy storage battery body 7, thereby performing a comprehensive pressure detection on the upper surface of the energy storage battery body 7; When the subsequent detection wheel 40 encounters a protrusion during its rolling process, the detection wheel 40 will move upward, causing the T-plate 38 to increase its squeezing force on the pressure sensor 43 through the second spring 42 and the pressure plate 41. At this time, the pressure displayed on the external display device increases, so that the staff can judge whether there is a protrusion on the surface of the energy storage battery body 7 based on whether the pressure displayed on the external display device increases. When the surface of the energy storage battery body 7 leaks, since the electrolyte is a viscous liquid, it will hinder the rotation of the detection wheel 40, causing the speed of the cross bar 39 to decrease. The photoelectric speed sensor 44 will increase the intensity or frequency of the photoelectric signal captured by the reflective sheet 45. At this time, the photoelectric speed sensor 44 can convert it into an electrical signal and transmit it to the external display device through a wire to indicate that the speed has decreased. At this time, the staff can judge whether the surface of the energy storage battery body 7 is leaking based on whether the speed displayed on the external display device has decreased. When the two clamping plates 11 fixedly connected to the two first rods 8 are aligned with the energy storage battery body 7 and the rest of the surface of the energy storage battery body 7 needs to be inspected, the two cylinders 35 are adjusted to contract and drive the inspection wheel 40 to move up to the initial position, and then the electric push rod 16 corresponding to one of the first rods 8 is adjusted to extend, driving the gear plate 17 to move toward the direction close to the gear 14. At this time, the electric push rod 16 drives the oil pump rod 28 to move through the connecting plate 29, so that the space in the oil pump frame 27 at this location increases, and then the oil pump frame 27 absorbs hydraulic oil from the cavity 2 through the connecting pipe 30, so that the hydraulic oil in the cavity 2 is reduced, and then the four The hydraulic oil in the rectangular groove 3 is reduced, and the four rectangular rods 4, under the elastic force of the four first springs 5, drive the bottom plate 6 to move downward, so that the bottom plate 6 is away from the lower end of the energy storage battery body 7. Then the tooth plate 17 moves to engage with the gear 14, and drives the gear 14 and the outer ring of the one-way bearing 13 to rotate forward. At this time, the outer ring of the one-way bearing 13 drives its inner ring to rotate, driving the round rod 10 to rotate forward, and then drives the energy storage battery body 7 to rotate, so that the energy storage battery body 7 can be changed. At this time, the bottom plate 6 is away from the lower end of the energy storage battery body 7, and thus will not affect the rotation of the energy storage battery body 7; After the energy storage battery body 7 is changed, the electric push rod 16 is adjusted to retract, driving the gear plate 17 to move in the direction away from the gear 14. At this time, the gear 14 and the outer ring of the one-way bearing 13 are driven to rotate in opposite directions. The outer ring of the one-way bearing 13 does not drive its inner ring to rotate, so that the position of the energy storage battery body 7 remains unchanged. As the electric push rod 16 retracts, the electric push rod 16 drives the oil pump rod 28 to move through the connecting plate 29, and squeezes the hydraulic oil in the oil pump frame 27 into the cavity 2 through the connecting pipe 30, so that the hydraulic oil in the cavity 2 increases. At this time, the four rectangular rods 4 drive the bottom plate 6 to move upward under the action of the hydraulic oil, so that the upper end of the bottom plate 6 is in contact with the lower end of the energy storage battery body 7, ensuring the stability of the energy storage battery body 7 during the subsequent pressure detection of the energy storage battery body 7. Then repeat the above detection steps; After the two clamping plates 11 fixedly connected to the two first rods 8 clamp and detect the energy storage battery body 7, the driving motor 25 rotates in the opposite direction to drive the bidirectional screw 26 to rotate in the opposite direction, driving the first plate 19 and the second plate 20 to move away from each other. At this time, the first plate 19 drives the two first rods 8 away from each other through the two fourth rods 21, and the second plate 20 drives the two second rods 9 closer to each other through the two fifth rods 22, thereby clamping the two clamping plates 11 fixedly connected to the two second rods 9 to the energy storage battery body 7. Then, the electric push rod 16 corresponding to one of the second rods 9 can be adjusted to extend, and then the above steps can be repeated to change the face of the energy storage battery body 7. In this way, pressure detection can be performed on all six faces of the rectangular energy storage battery body 7, avoiding the problem that the prior art can only detect cylindrical batteries, but cannot operate on rectangular batteries. At the same time, pressure detection can only be performed on the upper side of the battery, and pressure detection cannot be performed on other positions of the battery.
