Description

Technical Field

[0002] Battery quality and performance testing is an important part of the battery production quality inspection process. Whether it is the quality, capacity, safety, etc. of the battery, it needs to be tested to eliminate bad and defective products.

[0003] At present, the equipment for testing batteries is very mature. Workers only need to connect the batteries to the testing equipment to quickly and accurately test the results. However, the main problem is that this method requires workers to manually test one by one, which takes a long time and is cumbersome to operate. For batch battery testing in the workshop, the efficiency is poor.

[0004] The batteries in the workshop are usually transported by conveyor belts. Adding battery detection components on the conveyor belts for batch detection is an efficient detection method. However, since the conveyor belt is always moving, there are more batteries being transported in the future, and the battery detection takes a certain amount of time and the time may be uncertain, so it is more troublesome to detect directly on the conveyor belt, and it will affect the subsequent battery transportation. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a new energy vehicle battery testing device to solve the technical problem in the prior art of how to directly equip a testing mechanism on the conveyor line to perform batch testing without affecting the battery conveying itself.

[0009] A suction cup connected to the gas main pipe is arranged in the detection chamber, and the suction cup is fixedly connected to the front end of the telescopic rod. The inner end of the telescopic rod passes through the detection chamber and is slidably connected in the fixed cylinder. The fixed cylinder is fixedly connected to the detection turntable through a central connecting column.

[0010] Furthermore, an air extraction channel is provided at the center of the telescopic rod and the suction cup, which passes through the detection chamber and the inner cavity of the fixed cylinder, and the inner cavity of the fixed cylinder is connected to the gas main pipe through an internal air path. A first solenoid valve fixedly installed at the inner end of the telescopic rod is provided at the inner port of the air extraction channel.

[0011] Furthermore, the internal gas circuit includes:

[0012] A gas delivery branch pipe located in the central connecting column and a confluence cavity provided in the detection turntable, wherein both ends of the gas delivery branch pipe are respectively connected with the inner cavity of the fixing cylinder and the confluence cavity;

[0013] A fixed communicating ring and a connecting pipe are fixedly connected in the fixing seat, wherein the fixed communicating ring is rotationally connected to the detection turntable and is connected to the confluence cavity, and the connecting pipe is connected to the fixed communicating ring and the gas transmission main pipe.

[0014] Furthermore, a second solenoid valve is provided at the port of the gas transmission branch pipe located in the confluence chamber.

[0015] Furthermore, a rotating motor is provided in the fixing seat, the rotating motor is fixedly connected to the fixing seat via a bracket, and the output shaft of the rotating motor is also fixedly connected to the detection turntable.

[0028] Specific implementation method and principle

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0031] A first aspect of the present invention, as Figure 1 and Figure 2 As shown, the present invention includes a feed conveyor belt 100, a discharge conveyor belt 103 and a detection main body part, wherein the feed conveyor belt 100 is provided with one, and the discharge conveyor belt 103 is provided with multiple, the feed conveyor belt 100 continuously feeds the batteries to be tested into the detection main body part for testing, and different discharge conveyor belts 103 are used to send out batteries of different grades from different discharge conveyor belts 103 according to the test results, such as good products, qualified products, defective products, bad products, etc. after the battery 01 is tested, which not only realizes the normal transportation of the battery 01, but also can automatically classify it.

[0032] The main detection part includes a detection turntable 101 and a plurality of detection chambers 102 arranged at equal angles on the edge of the detection turntable 101. The detection chamber 102 is fixedly connected to the detection turntable 101 and the chamber opening of the detection chamber 102 faces outward. A detection module 105 is also installed on the detection chamber 102. A branch cable 106 is connected to the detection module 105. The other ends of all branch cables 106 are connected to a main cable 107. The other end of the main cable 107 is connected to an external master control device for detecting the performance of the battery 01.

[0033] like Figure 3 and Figure 4As shown, the detection turntable 101 is rotatably connected to the fixed seat 104, and the fixed seat 104 is also connected to the gas main pipe 118, and the gas main pipe 118 is connected to the external air pump. The detection chamber 102 is provided with a suction cup 111 connected to the gas main pipe 118, and the suction cup 111 is fixedly connected to the front end of the telescopic rod 110. The inner end of the telescopic rod 110 passes through the detection chamber 102 and is slidably connected in the fixed cylinder 109, and the fixed cylinder 109 is fixedly connected to the detection turntable 101 through the central connecting column 108. A suction channel 112 that runs through the detection chamber 102 and the inner cavity of the fixed cylinder 109 is provided at the center of the telescopic rod 110 and the suction cup 111, and the inner cavity of the fixed cylinder 109 is connected to the gas main pipe 118 through the internal gas path. The inner port of the suction channel 112 is provided with a first solenoid valve 113 fixedly installed at the inner end of the telescopic rod 110.

[0034] Preferably, Figure 3 and Figure 5 As shown, the internal gas circuit includes a gas delivery branch pipe 114 located in the central connecting column 108 and a confluence cavity 115 provided in the detection turntable 101. The two ends of the gas delivery branch pipe 114 are respectively connected to the inner cavity of the fixed cylinder 109 and the confluence cavity 115. A fixed communication ring 116 and a connecting pipe 117 are also fixedly connected to the fixed seat 104. The fixed communication ring 116 is rotatably connected to the detection turntable 101 and is connected to the confluence cavity 115. The connecting pipe 117 connects the fixed communication ring 116 and the gas delivery main pipe 118. In addition, a second solenoid valve 122 is provided at the port of the gas delivery branch pipe 114 located in the confluence cavity 115. The suction cups 111 in different detection chambers 102 are controlled to work by the first solenoid valve 113 and the second solenoid valve 122.

[0035] Among them, the detection turntable 101 rotates periodically to ensure that there is an empty detection bin 102 facing the feed conveyor belt 100 at each pause. When the feed conveyor belt 100 conveys a battery 01 to be detected into the empty detection bin 102 and sticks to the suction cup 111 in the detection bin 102, the first solenoid valve 113 and the second solenoid valve 122 connected to the suction cup 111 in the detection bin 102 are opened. At this time, the external air pump draws air, so that negative pressure is generated in the inner cavity of the fixed cylinder 109, and then the suction cup 111 generates suction to adsorb and fix the battery 01 to be detected. At this time, because the battery 01 blocks the suction cup 111, the negative pressure in the inner cavity of the fixed cylinder 109 will drive the telescopic rod 110 to slide inward and shrink, and then slide backward with the suction cup 111 and the battery 01, so that the battery 01 completely enters the detection bin 102 and stops at a predetermined position. Then, the detection module 105 is connected to the connector of the battery 01 to detect the battery 01 .

[0036] After the above process is completed, the detection turntable 101 can perform the next periodic rotation, so that the next empty detection bin 102 can dock with the feeding conveyor belt 100, and then repeat the above detection and feeding process.

[0037] After the battery test is performed, batteries 01 of different grades can be sent out from different unloading conveyor belts 103 according to the test results, such as good products, qualified products, defective products, and bad products. After the test chamber 102 where the corresponding grade of battery 01 is located is transferred to the corresponding unloading conveyor belt 103, the external air pump inflates the air, and the airflow enters the connecting pipe 117 through the gas main pipe 118, and then enters the confluence chamber 115 through the connecting pipe 117. Therefore, high air pressure will be generated in the confluence chamber 115, and the corresponding second solenoid valve 122 connected to the air path connected to the suction cup 111 in the above-mentioned test chamber 102 will be opened first, and the airflow will enter the corresponding fixed cylinder 109 through the corresponding gas branch pipe 114. At this time, the first solenoid valve 113 has not been opened, so the high pressure in the inner cavity of the fixed cylinder 109 will drive the telescopic rod 110 to slide outward, and then slide outward with the suction cup 111 and the battery 01, so that the battery 01 moves to the corresponding unloading conveyor belt 103. Then the first solenoid valve 113 is opened again, and the suction cup 111 no longer absorbs the battery 01 , but blows air toward the battery 01 to cooperate with the rotating discharge conveyor belt 103 to send the battery 01 out.

[0038] It should be noted that after the detection turntable 101 rotates one cycle (ie, rotates 360°), it is necessary to ensure that the detection chamber 102 is in an empty state when it docks with the feed conveyor belt 100 again.

[0039] Preferably, a connecting bridge 123 for docking the inspection bin 102 with the feed conveyor belt 100 and the discharge conveyor belt 103 is fixedly connected on the side wall of the inspection turntable 101 below the opening of each inspection bin 102, and the lower end surface of the connecting bridge 123 is set as a concave arc surface that matches the two conveyor belts.

[0040] On the other hand, Figure 3 As shown, a rotating motor 119 is provided in the fixing seat 104, and the rotating motor 119 is fixedly connected to the fixing seat 104 through a bracket 120, and the output shaft of the rotating motor 119 is also fixedly connected to the detection turntable 101, and the bracket 120 is also rotatably connected to a roller 121, and the roller 121 is rollingly connected to the detection turntable 101. The rotating motor 119 is a servo motor or a stepping motor, and the rotating motor 119 is controlled by a controller to work, thereby driving the detection turntable 101 to rotate periodically. DETAILED DESCRIPTION

[0041] The rotating motor 119 drives the detection turntable 101 to rotate periodically, ensuring that there is an empty detection bin 102 facing the feed conveyor belt 100 at each pause. When the feed conveyor belt 100 delivers a battery 01 to be detected into the empty detection bin 102 and sticks to the suction cup 111 in the detection bin 102, the first solenoid valve 113 and the second solenoid valve 122 connected to the suction cup 111 in the detection bin 102 are opened. At this time, the external air pump draws air, so that negative pressure is generated in the inner cavity of the fixed cylinder 109, and then the suction cup 111 generates suction to fix the battery 01 to be detected. At this time, because the battery 01 blocks the suction cup 111, the negative pressure in the inner cavity of the fixed cylinder 109 will drive the telescopic rod 110 to slide inward and shrink, and then slide backward with the suction cup 111 and the battery 01, so that the battery 01 completely enters the detection bin 102 and stops at a predetermined position. Then, the detection module 105 is connected to the connector of the battery 01 to detect the battery 01 .

[0042] After the battery 01 feeding process is completed, the detection turntable 101 can perform the next periodic rotation, so that the next empty detection bin 102 is docked with the feeding conveyor belt 100, and then the detection feeding process is repeated.

[0043] After the battery test is performed, batteries 01 of different qualities can be sent out from different discharging conveyor belts 103 according to the test results.

[0044] Specifically, the external air pump blows air, and the airflow enters the connecting pipe 117 through the gas main pipe 118, and then enters the confluence chamber 115 through the connecting pipe 117. Therefore, high air pressure will be generated in the confluence chamber 115, and the corresponding second solenoid valve 122 connected to the air path connected to the suction cup 111 in the above-mentioned detection chamber 102 will be opened first, and the airflow will enter the corresponding fixed cylinder 109 through the corresponding gas branch pipe 114. At this time, the first solenoid valve 113 has not been opened, so the high pressure in the inner cavity of the fixed cylinder 109 will drive the telescopic rod 110 to slide outward, and then slide outward with the suction cup 111 and the battery 01, so that the battery 01 moves to the corresponding discharge conveyor belt 103. Then the first solenoid valve 113 is opened again, and the suction cup 111 no longer absorbs the battery 01, but blows air to the battery 01 to cooperate with the rotating discharge conveyor belt 103 to send the battery 01 out.

[0045] Based on the above, the present invention sets a rotation detection mechanism on the conveyor line, in which multiple battery detection components are provided. After a battery detection component receives a battery, it will automatically rotate so that the next empty battery detection component can dock with the subsequent battery. Therefore, while batch testing the batteries, it does not affect the subsequent battery transportation. And after the battery testing is carried out, a feeding conveyor belt and multiple discharging conveyor belts can send batteries of different grades from different discharging conveyor belts 103 according to the test results, which not only realizes the normal transportation of the battery 01, but also can automatically classify them. The suction cup 111 is used to realize both the transfer function and the positioning function of the battery 01, ensuring the stability and position accuracy of the battery 01 during the entry and exit and detection process.
