Lithium batteries, especially lithium-ion batteries, are very reliable in normal use, but they may overheat, catch fire, or explode under extreme conditions such as short circuits.

[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention. Example 1

[0022] See also Figure 1 - Figure 7A protective electrical contact battery connector detection device includes: an operating table 1; a host 6 and a slide 8 are installed on the operating table 1; a feeding assembly 2, which is used to transport lithium batteries to a test position in batches, and the feeding assembly 2 is arranged on the operating table 1. The feeding assembly 2 includes a motor 21, which is installed on the operating table 1 through a bracket.

A plurality of material platforms 26 are connected to the conveyor belt 25, and four battery bodies 9 are placed on the material platform 26. A hopper 27 is installed on the operating table 1 through a bracket, and the inner wall of the hopper 27 is equipped with a first guide fork 28 and a third guide fork 28. Guide fork 210, the inner wall of the hopper 27 is slidably installed with a No. 2 guide fork 29, the No. 2 guide fork 29 is located between the No. 1 guide fork 28 and the No. 3 guide fork 210, the No. 3 guide fork 210 is located above the conveyor belt 25, and the No. 1 guide fork 28, the No. 2 guide fork 29 and the No. 3 guide fork 210 are respectively provided with four unloading chutes, the rear side of the No. 2 guide fork 29 is connected with a roller 215, the rear ends of the main shaft 22 and the slave shaft 23 are respectively connected with cams 211, and two No. 1 frames 212 are installed on the operating table 1, and a slide rod 213 is slidably installed between the two No. 1 frames 212, and the slide rod 213 is provided with two inner slide grooves, and the two cams 211 are respectively slidably connected with the two inner slide grooves of the slide rod 213 through bearings, and the two cams 211 drive the slide rod 213 through bearings The two No. 1 frames 212 slide back and forth up and down, and the sliding groove rod 213 drives the diamond rod 214 to reciprocate up and down. The sliding groove rod 213 is connected to the diamond rod 214, and the inner wall of the diamond rod 214 is slidably connected to the roller 215. When the diamond rod 214 moves downward, the roller 215 first slides along the straight edge of the diamond rod 214. When the roller 215 contacts a bevel above the diamond rod 214, the roller 215 slides to the left by the reverse thrust of the diamond rod 214. When the roller 215 slides to the left, it drives the No. 2 guide fork 29 to slide to the left. When the diamond rod 214 moves downward into place and then moves upward, the roller 215 contacts an inclined surface below the diamond rod 214 after a period of time and slides to the right to reset, and the No. 2 guide fork 29 slides to the right synchronously. After the second guide fork 29 moves to the left, the four battery bodies 9 above the second guide fork 29 fall into the four feeding troughs on the second guide fork 29. After the second guide fork 29 moves to the right, the four feeding troughs of the second guide fork 29 are connected with the four feeding troughs of the third guide fork 210. The four battery bodies 9 in the second guide fork 29 fall into the four feeding troughs of the third guide fork 210. The four battery bodies 9 slide along the four feeding troughs of the third guide fork 210 onto the material platform 26 below. Two short rods 217 are installed on the first guide fork 28. The two short rods 217 are sleeved with a dredging frame 216. The inner wall of the hopper 27 is rotatably connected to a pry bar 218. The diamond rod 214 is connected to a shift rod 219. One end of the pry bar 218 is connected to the dredging frame 216.The other end of the pry bar 218 is located on the movement track of the shift rod 219. There is a certain gap between the connection between the dredging frame 216 and the two short rods 217, so that the dredging frame 216 can move on the two short rods 217. When the other end of the pry bar 218 moves upward, it drives the dredging frame 216 to move upward. When the shift rod 219 is no longer in contact with the pry bar 218, the dredging frame 216 is reset by its own gravity, and the pry bar 218 is reset accordingly. When the dredging frame 216 moves, it can promote the falling of multiple battery bodies 9 in the hopper 27 to avoid material blockage. The test assembly 3 is used to perform a short circuit test on the lithium battery. The test assembly 3 is set on the operating table 1. The test assembly 3 includes a second frame 31. The slide rod 213 is connected to a right-angle rod 32. The end of the right-angle rod 32 away from the slide rod 213 is slidably connected to the second frame 31. The right-angle rod 32 is connected to a cooling box 41. The interior of the cooling box 41 is connected with four short-circuit wires 33. The coolant in the cooling box 41 cools down the four short-circuit wires 33 to prevent the short-circuit wires 33 from being overheated and burned after a long period of short-circuit testing. Both ends of the short-circuit wires 33 are positioned On the outside of the cooling box 41, two contact rods 34 are connected to the right-angle rod 32, two insulating blocks 36 are connected to the base 24 through a spring, four contacts 35 are connected to the inner wall of the insulating block 36, a temperature probe 7 is installed on the base 24, the two insulating blocks 36 are respectively located on both sides of the conveyor belt 25, the two contact rods 34 are in contact with the two insulating blocks 36 during movement, the eight contacts 35 are in contact with the two ends of the four short-circuit wires 33 during movement, and the eight contacts 35 are connected to the host 6 through wires. The host 6 is located in front of the conveyor belt 25. The slide 8 is located on the left side of the conveyor belt 25, and the temperature probe 7 is located between the cooling box 41 and the slide 8. When the four battery main bodies 9 move to the bottom of the four short-circuit wires 33, the motor 21 stops rotating and the battery main body 9 stops moving. During this process, the four short-circuit wires 33 move downward, and the two ends of the four short-circuit wires 33 move to the two ends of the four battery main bodies 9 respectively. The eight contacts 35 contact the two ends of the four short-circuit wires 33 during the movement, so that the eight contacts 35 push the two ends of the four short-circuit wires 33 against the two ends of the four battery main bodies 9. When the two ends of the short-circuit wires 33 contact the two ends of the battery main body 9, the battery main body 9 is short-circuited. At the same time, the two contacts 35 transmit the current and voltage data to the host 6 through the wires, and the host 6 displays the current and voltage data of the battery main body 9 through the display. The staff can observe the changes in current and voltage during the short-circuit process of the battery main body 9. At the same time, the temperature probe 7 detects the temperature of the short-circuited battery main body 9 and transmits the temperature data to the host 6 through the wire. The host 6 can display the current, voltage and temperature data of the battery main body 9, thereby achieving the effect of automatic testing. Through the cooperation of the feeding component 2 and the testing component 3, the hopper 27 can automatically unload the battery bodies 9 into batches onto the material table 26. The multiple material tables 26 transport the battery bodies 9 to the four short-circuit wires 33 for short-circuit testing through movement, thereby achieving the effect of automatic feeding. The four short-circuit wires 33 cooperate with the eight contacts 35 to perform short-circuit testing on the four battery bodies 9, thereby achieving the effect of automatically and simultaneously performing short-circuit testing on the four battery bodies 9. The wiring process avoids manual operation, which improves work efficiency while also improving the safety of the staff. While unloading, the clearing frame 216 can promote the unloading process through movement to avoid blockage in the hopper 27 and affect subsequent operations.

[0023] For further information, see Figure 8 , a cooling assembly 4 is used to cool the test assembly 3. The cooling assembly 4 is arranged on the operating table 1. The cooling assembly 4 includes a fixed rod 42, which is mounted on the slide rod 213. A connecting rod 43 is hinged on the fixed rod 42. A piston 44 is slidably mounted on the operating table 1. The piston 44 is hinged to one end of the connecting rod 43 away from the fixed rod 42. A pressure cabin 45 is installed on the operating table 1. The inner wall of the pressure cabin 45 is slidably connected to the outer wall of the piston 44. A cooling pipe 46 is connected to the pressure cabin 45. The end of the cooling pipe 46 away from the pressure cabin 45 is connected to the cooling box 41. The cooling box 41 is also connected to a return pipe 47. A buffer chamber 48 is installed on the operating table 1. The end of the return pipe 47 away from the cooling box 41 is connected to the buffer chamber 48. A connecting pipe 49 is connected between the buffer chamber 48 and the pressure cabin 45. When the piston 44 moves to the right, the coolant in the pressure cabin 45 is transported through the cooling pipe 46 by pressure. It is sent to the cooling box 41, and the coolant in the cooling box 41 is transported to the buffer chamber 48 through the return pipe 47 by pressure. When the piston 44 moves to the left, the pressure chamber 45 uses negative pressure to draw the coolant in the buffer chamber 48 into the buffer chamber 48 through the connecting pipe 49, thereby achieving the effect of coolant circulation. The connecting pipe 49 and the cooling pipe 46 are respectively provided with a check valve inside. The check valves in the connecting pipe 49 and the cooling pipe 46 prevent the coolant from flowing back. Through the setting of the cooling component 4, the coolant in the cooling box 41 has a cooling effect on the four short-circuit wires 33, thereby preventing the short-circuit wires 33 from overheating and burning after long-term use, thereby extending the service life of the short-circuit wires 33, and the coolant can circulate between the cooling box 41, the buffer chamber 48 and the pressure chamber 45, so that the coolant dissipates its own heat during the flow process, thereby maintaining the cooling effect of the coolant in the cooling box 41.

[0024] Further, see Figure 9 - Figure 11, the charging assembly 5 is used to replenish the power of the lithium battery. The charging assembly 5 is set on the operating table 1. The charging assembly 5 includes a No. 3 frame 51, which is installed on the base 24. Two movable blocks 52 are slidably installed on the No. 3 frame 51. A gear 53 is rotatably installed on the No. 3 frame 51. Racks 54 are respectively installed on the two movable blocks 52. The two racks 54 are arranged in a circular array with the gear 53 as the center. The two racks 54 are engaged with the gear 53. When one of the racks 54 moves, it will drive the other rack 54 to move in the opposite direction through the gear 53. The slide rod 213 is on It is connected with a chute column 57, and a round rod 58 is installed on one of the movable blocks 52 through a bracket. The outer wall of the round rod 58 is slidably connected to the inner wall of the chute column 57. A charging module 56 is installed on the operating table 1. The charging module 56 is connected to the host 6 through a wire. Eight charging lines 55 are connected to the charging module 56. The eight charging lines 55 pass through the two movable blocks 52 respectively. The movable blocks 52 are connected to the four charging lines 55. When one of the material tables 26 moves to the bottom of the third rack 51, the eight charging lines 55 move toward the two ends 9 of the four battery main bodies respectively. When the eight charging lines 55 are connected, the charging lines 55 are connected to the main body 6. When the two ends of the four battery bodies 9 are touched by the two movable blocks 52, the battery bodies 9 and the two movable blocks 52 stop moving, and the host 6 transmits power to the charging module 56 through the wires. The charging module 56 charges the four battery bodies 9 through the eight charging wires 55, and the charging and short-circuit tests are performed simultaneously; two baffles 59 are rotatably mounted on the base 24, and a torsion spring 510 is connected between the baffle 59 and the base 24. The two baffles 59 are respectively located below the two movable blocks 52, and the two baffles 59 are respectively in contact with the ends of the eight charging wires 55 away from the charging module 56. The baffles 59 are in contact with the ends of the eight charging wires 55 away from the charging module 56. The period when the wire 55 is not working protects the end of the charging wire 55; through the setting of the charging component 5, the battery main body 9 can be replenished with electricity through the cooperation of the charging module 56 and the eight charging wires 55 before the short-circuit test is carried out, so as to avoid the battery main body 9 from being short-circuited due to insufficient power, resulting in the short-circuit duration failing to meet the requirements during the subsequent short-circuit test, thereby affecting the accuracy of the test results; through the setting of the two baffles 59, the two baffles 59 can protect the charging wire 55 during the period when the eight charging wires 55 are not working, thereby extending the service life of the charging wire 55.

[0025] With the above structure, the working principle of this case is that the staff puts multiple battery bodies 9 into the hopper 27, of which four battery bodies 9 fall along the four discharge troughs of the No. 1 guide fork 28 onto the No. 2 guide fork 29. The No. 2 guide fork 29 temporarily blocks the falling path of the battery body 9. After starting the motor 21, the motor 21 drives the main shaft 22 to rotate, the main shaft 22 drives the conveyor belt 25 to rotate, the conveyor belt 25 drives the slave shaft 23 to rotate, and the multiple material platforms 26 on the conveyor belt 25 move with the conveyor belt 25. The main shaft 22 and the slave shaft 23 rotate synchronously, and the main shaft 22 and the slave shaft 23 respectively drive the two cams 211 to rotate, and the two cams 211 drive the slide rod 213 through the bearing to slide up and down on the two No. 1 racks 212. , the slide rod 213 drives the diamond rod 214 to reciprocate up and down. When the diamond rod 214 moves downward, the roller 215 first slides along the straight edge of the diamond rod 214. When the roller 215 contacts a beveled edge above the diamond rod 214, the roller 215 slides to the left by the reverse thrust of the diamond rod 214. When the roller 215 slides to the left, it drives the second guide fork 29 to slide to the left. When the diamond rod 214 moves downward to the position and moves upward, the roller 215 contacts an inclined surface below the diamond rod 214 after a period of time and slides to the right to reset. The second guide fork 29 slides to the right synchronously to reset, so that the second guide fork 29 can perform a reciprocating motion every time the cam 211 rotates one circle, and the second guide fork 29 moves to the left. After that, the four battery bodies 9 above the No. 2 guide fork 29 fall into the four feeding troughs on the No. 2 guide fork 29. After the No. 2 guide fork 29 moves to the right, the four feeding troughs of the No. 2 guide fork 29 are connected with the four feeding troughs of the No. 3 guide fork 210. The four battery bodies 9 in the No. 2 guide fork 29 fall into the four feeding troughs of the No. 3 guide fork 210. The four battery bodies 9 slide along the four feeding troughs of the No. 3 guide fork 210 to the material table 26 below. The material table 26 transports the four battery bodies 9 to the test assembly 3 for testing during the subsequent movement. The multiple battery bodies 9 in the hopper 27 intermittently fall onto other material tables 26 according to the above-mentioned movement trajectory along with the movement of the No. 2 guide fork 29; when the diamond rod 214 moves downward When the lever 219 is in contact with the pry bar 218, the rhombus rod 214 drives the shift rod 219 to move downward. During the downward movement of the shift rod 219, it contacts one end of the pry bar 218 and drives the other end of the pry bar 218 downward. By utilizing the lever principle, the other end of the pry bar 218 moves upward. Since there is a certain gap between the connection between the dredging frame 216 and the two short rods 217, the dredging frame 216 can move on the two short rods 217. When the other end of the pry bar 218 moves upward, it drives the dredging frame 216 to move upward. When the shift rod 219 is no longer in contact with the pry bar 218, the dredging frame 216 is reset by its own gravity, and the pry bar 218 is reset accordingly. When the dredging frame 216 moves, it can promote the falling of multiple battery bodies 9 in the hopper 27 to avoid material blockage.When the slide rod 213 reciprocates up and down, the slide rod 213 drives the right-angle rod 32 to slide reciprocatingly up and down on the second frame 31. When the right-angle rod 32 moves downward, it drives the cooling box 41 to move downward. The cooling box 41 drives the four short-circuit wires 33 to move downward. When the right-angle rod 32 moves downward, it also drives the two contact rods 34 to move downward. When the two contact rods 34 move downward, they contact the two insulating blocks 36 respectively, so that the two insulating blocks 36 move toward each other along the arc of the edges of the two contact rods 34. When the two insulating blocks 36 move, they drive the eight contacts 35 Synchronous movement, while the right-angle rod 32 moves downward, one of the material platforms 26 moves to the left with the four battery bodies 9. When the four battery bodies 9 move below the four short-circuit wires 33, the motor 21 stops rotating and the battery bodies 9 stop moving. During this process, the four short-circuit wires 33 move downward, and the two ends of the four short-circuit wires 33 move to the two ends of the four battery bodies 9 respectively. The eight contacts 35 contact the two ends of the four short-circuit wires 33 during the movement, so that the eight contacts 35 press the two ends of the four short-circuit wires 33 against the two ends of the four battery bodies 9. When the two ends of the short-circuit wires 33 contact the two ends of the battery bodies 9, the battery bodies 9 are short-circuited. At the same time, the two contacts 35 transmit the current and voltage data to the host 6 through the wires. The host 6 displays the current and voltage data of the battery body 9 through the display. The staff can observe the changes in current and voltage during the short-circuit process of the battery body 9. At the same time, the temperature probe 7 detects the temperature of the short-circuited battery body 9 and transmits the temperature data to the host 6 through the wire. The host 6 can display the current, voltage and temperature data of the battery body 9. When a test is performed, After a certain period of detection, the motor 21 rotates again, the right-angle rod 32 starts to move upward, the two contact rods 34 gradually break away from the contact with the two insulating blocks 36, and the two insulating blocks 36 are reset by the elastic force of the springs between the base 24. The tested battery body 9 follows the material table 26 to move to the left. When the material table 26 moves to the leftmost side of the conveyor belt 25 and starts to turn downward, the battery body 9 falls onto the slide plate 8 and slides to the next process, achieving the effect of automatic testing; every time the motor 21 rotates one circle, multiple material tables 26 move a fixed distance, and the hopper 27 performs a Unloading, four battery main bodies 9 fall onto the material platform 26 that just moves to the bottom of the third guide fork 210. At the same time, multiple material platforms 26 with four battery main bodies 9 move to the left, and the motor 21 rotates one circle and then stops for a period of time. During this time, one of the material platforms 26 is located below the cooling box 41 for short-circuit testing, and one of the material platforms 26 is located below the third rack 51 for charging. The time when the motor 21 stops rotating is equal to the time when the battery main body 9 is short-circuited. The staff can adjust the time when the motor 21 stops through the controller according to the test requirements;The coordination of the feeding assembly 2 and the testing assembly 3 enables the hopper 27 to automatically unload battery cells 9 in batches of four onto the feeding table 26. The multiple feeding tables 26 then move to transport the battery cells 9 to the four short-circuit wires 33 for short-circuit testing, achieving the effect of automatic feeding. The four short-circuit wires 33 cooperate with the eight contacts 35 to perform short-circuit testing on the four battery cells 9, achieving the effect of automatically and simultaneously short-circuiting all four battery cells 9. This eliminates manual operation during the wiring process, improving both work efficiency and worker safety. During unloading, the unblocking frame 216 can facilitate the unloading process through movement, preventing blockage in the hopper 27 and the subsequent impact on subsequent operations.

[0026] The cooling box 41, the buffer chamber 48 and the pressure chamber 45 are filled with coolant. The coolant in the cooling box 41 cools down the four short-circuit wires 33 to prevent the short-circuit wires 33 from being overheated and burned after a long period of short-circuit testing. When the slide rod 213 reciprocates up and down, it drives the fixed rod 42 to move synchronously. The fixed rod 42 drives the piston 44 to move back and forth on the operating table 1 through the connecting rod 43. When the piston 44 moves to the right, the coolant in the pressure chamber 45 is transported to the cooling box 41 through the cooling pipe 46 by pressure. The coolant in the cooling box 41 is transported to the buffer chamber 48 through the return pipe 47 by pressure. When the piston 44 moves to the left, the pressure chamber 45 is The coolant in the buffer chamber 48 is pumped into the buffer chamber 48 through the connecting pipe 49 by utilizing negative pressure, and the above steps are subsequently repeated to achieve the effect of circulating the coolant. The check valves in the connecting pipe 49 and the cooling pipe 46 prevent the coolant from flowing back. Through the setting of the cooling assembly 4, the coolant in the cooling box 41 has a cooling effect on the four short-circuit wires 33, thereby preventing the short-circuit wires 33 from overheating and burning after long-term use, thereby extending the service life of the short-circuit wires 33, and the coolant can circulate between the cooling box 41, the buffer chamber 48 and the pressure cabin 45, so that the coolant dissipates its own heat during the flow, thereby maintaining the cooling effect of the coolant in the cooling box 41.

[0027] When the chute rod 213 reciprocates up and down, it drives the chute column 57 to move synchronously. When the chute column 57 moves downward, the chute column 57 drives one of the movable blocks 52 to move in the direction close to the gear 53 through the round rod 58. Since when one of the racks 54 moves, it will drive the other rack 54 to move in the opposite direction through the gear 53, and the two racks 54 are respectively connected to the two movable blocks 52, so that when one of the movable blocks 52 moves in the direction close to the gear 53, the other movable block 52 also moves in the direction close to the gear 53. The two movable blocks 52 respectively drive the eight charging wires 55 to move synchronously. When one of the material platforms 26 moves to the bottom of the third rack 51, the eight charging wires 55 respectively move toward the two ends 9 of the four battery main bodies. When the eight charging wires 55 contact the two ends of the four battery main bodies 9, the battery main bodies 9 and the two movable blocks 52 stop moving, and the host 6 transmits electricity to the charging module 56 through the wires. The charging module 56 charges the four battery main bodies 9 through the eight charging wires 55. Charging and short-circuit testing are carried out simultaneously. When the chute column 57 moves upward, the chute column 57 The slot column 57 drives one of the movable blocks 52 to reset through the round rod 58, and the eight charging cables 55 are reset accordingly; when the four charging cables 55 on the same side move toward the direction close to the gear 53, one end of the four charging cables 55 pushes the baffle 59, causing the baffle 59 to swing. Before the charging cables 55 contact the battery body 9, the baffle 59 breaks away from contact with the end of the charging cables 55. When the four charging cables 55 are reset, the baffle 59 follows the four charging cables 55 to reset due to the elastic force of the torsion spring 510. The baffle 59 is in the period when the charging cables 55 are not working. The segment protects the end of the charging line 55; through the setting of the charging component 5, the battery main body 9 can be replenished with electricity through the cooperation of the charging module 56 and the eight charging lines 55 before the short-circuit test, so as to avoid the battery main body 9 from being short-circuited due to insufficient power, resulting in the short-circuit duration failing to meet the requirements during the subsequent short-circuit test, thereby affecting the accuracy of the test results; through the setting of the two baffles 59, the two baffles 59 can protect the charging lines 55 during the time period when the eight charging lines 55 are not working, thereby extending the service life of the charging lines 55.
