[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0049] The embodiment of the present application provides a mobile power battery detection device, which solves the problem of manually sampling mobile power batteries in proportion to conduct safety performance tests, which requires additional random inspections, resulting in cumbersome detection steps. In the process of random inspection and transportation of mobile power batteries, accidental damage to the lithium battery will affect the inspection results, requiring re-inspection, and the accuracy of the data cannot be guaranteed. When the currently clamped mobile power battery is set as a random inspection sample, the processor controls the first cylinder 5 to move the positioning unit 8 toward the mobile power battery. At this time, the processor controls the first cylinder 5 to apply a specified pressure to perform a pressure test on the mobile power battery. After the test is completed, the first transmission platform 31 is started, so that the battery processing part platform 33 drives the mobile power battery to be under the loading and unloading robot 2, and the mobile power battery is adsorbed and placed on the battery processing part platform 33 of the second transmission platform 32 by the loading and unloading robot 2 for transmission to perform charge and discharge tests on the mobile power battery.

[0050] Under the action of the second transmission platform 32, the battery processing platform 33 drives the mobile power battery to move to the bottom of the third cylinder 7, and the third cylinder 7 is started by the processor to drive the control test unit 9 to move downward, and the mobile power battery is charged and discharged to detect whether the charge and discharge data are normal. A processor is provided on the detection platform 1, and the processor controls the coordination of the loading and unloading robot 2, the docking unit 3, the first cylinder 5, the second cylinder 6, the third cylinder 7, the positioning unit 8 and the test unit 9 to complete the detection and random inspection of the mobile power battery.

[0051] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] The embodiment of the present invention discloses a mobile power supply battery detection device.

[0053] Example 1:

[0054] According to the attached Figure 1-11 As shown, it includes a detection platform 1, on which the following are provided:

[0055] The loading and unloading robot 2 is installed on the detection platform 1. The loading and unloading robot 2 is used to suck the mobile power battery to a specified position. By sucking the mobile power battery by the loading and unloading robot 2, the mobile power battery is conveniently placed on the battery processing platform 33 of the first transmission platform 31, and the mobile power battery parameters are tested after positioning. Alternatively, after the mobile power battery is pressure tested, the mobile power battery is placed on the battery processing platform 33 of the second transmission platform 32 to perform charging and discharging tests on the mobile power battery, thereby realizing automatic random inspection.

[0056] It should be emphasized that when the mobile power battery is detected, the processor controls the loading and unloading robot 2 to start, and the loading and unloading robot 2 identifies the mobile power battery through the camera, and detects whether the mobile power battery is under the loading and unloading robot 2 through the camera on the loading and unloading robot 2. The number of detection and recognition times is set. If the recognition and detection cannot be performed for many times, a fault warning is issued. The recognition and detection can be set to a cycle detection number as needed;

[0057] A docking unit 3 is installed on the detection platform 1 and is used to transport mobile power batteries;

[0058] Specifically disclosed, when a mobile power battery is detected by the camera on the loading and unloading robot 2, the robotic arm in the loading and unloading robot 2 is controlled to move, and the suction cup on the robotic arm is positioned directly above the mobile power battery to suck the mobile power battery. The robotic arm on the loading and unloading robot 2 then places the mobile power battery on the battery processing part platform 33 of the first transmission platform 31, and the docking unit 3 drives the movement of the mobile power battery to perform positioning and parameter detection respectively;

[0059] Furthermore, when the mobile power battery is detected to be qualified, the mobile power battery is reset through the battery processing platform 33 on the first transmission platform 31, and then the mobile power battery is sucked and transmitted by the loading and unloading robot 2, and a new mobile power battery is replaced for testing. The unqualified mobile power batteries are sucked and collected and placed together for manual inspection to determine the problem.

[0060] The mounting platform 4 is mounted on the detection platform 1, and the first cylinder 5, the second cylinder 6 and the third cylinder 7 are mounted on the mounting platform 4;

[0061] A positioning unit 8 is installed below the mounting platform 4 and is connected to the output end of the first cylinder 5. The positioning unit 8 is used to position and pressure test the mobile power battery.

[0062] It is particularly disclosed that when the currently clamped mobile power battery is set as a random inspection sample, the loading and unloading robot 2 starts the first transmission platform 31, so that the battery processing part platform 33 is transported along the track on the first transmission platform 31, and the mobile power battery on the battery processing part platform 33 is transported to the bottom of the positioning unit 8. At this time, the processor controls the first cylinder 5 to drive the positioning unit 8 to move downward, so that the positioning unit 8 moves toward the mobile power battery.

[0063] Furthermore, at this time, the processor controls the first cylinder 5 to apply a specified pressure to perform a pressure test on the mobile power battery. After the test is completed, the first transmission platform 31 is started, so that the battery processing part platform 33 drives the mobile power battery to be under the loading and unloading robot 2, and the mobile power battery is adsorbed and placed on the battery processing part platform 33 of the second transmission platform 32 through the loading and unloading robot 2, and the mobile power battery is transported to perform a charge and discharge test.

[0064] The test unit 9 is installed below the mounting platform 4 and is connected to the output ends of the second cylinder 6 and the third cylinder 7. The two test units 9 are used for voltage detection of the mobile power battery and charge and discharge test of the mobile power battery respectively.

[0065] Furthermore, under the action of the second transmission platform 32, the battery processing platform 33 drives the mobile power battery to move to the bottom of the third cylinder 7, and the processor controls the third cylinder 7 to start, and the third cylinder 7 drives the control test unit 9 to move downward, and performs a charge and discharge test on the mobile power battery to detect whether the charge and discharge data is normal.

[0066] It is particularly disclosed that a processor is provided on the detection platform 1, which controls the coordination of the loading and unloading robot 2, the docking unit 3, the first cylinder 5, the second cylinder 6, the third cylinder 7, the positioning unit 8 and the testing unit 9 to complete the detection and random inspection of the mobile power battery.

[0067] The docking unit 3 is located below the loading and unloading robot 2 and the installation platform 4. The docking unit 3 includes a first transmission platform 31 and a second transmission platform 32. The first transmission platform 31 and the second transmission platform 32 are both transmission-connected to a battery processing part platform 33. The battery processing part platform 33 cooperates with the first transmission platform 31 and the second transmission platform 32 to transport the mobile power battery to the bottom of the first cylinder 5, the second cylinder 6 and the third cylinder 7. The first transmission platform 31 and the second transmission platform 32 are installed in the detection platform 1. A driving mechanism is provided in the detection platform 1 for cooperating with the first transmission platform 31 and the second transmission platform 32 to drive the battery processing part platform 33 to move.

[0068] The positioning unit 8 comprises:

[0069] an extrusion seat 81 , which is located directly above the first transport platform 31 ;

[0070] The first connecting seat 82 has its top end surface installed with the output end of the first cylinder 5. The first connecting seat 82 is located directly above the extrusion seat 81. The first connecting seat 82 cooperates with the first cylinder 5 to drive the extrusion seat 81 to move.

[0071] Four positioning components 83 are distributed at the four corners of the extrusion seat 81 . The positioning components 83 cooperate with the extrusion seat 81 to position the mobile power battery.

[0072] When the mobile power battery on the battery processing platform 33 is transferred to the bottom of the positioning unit 8, the processor controls the first cylinder 5 to drive the positioning unit 8 to move downward, so that the positioning unit 8 moves toward the mobile power battery;

[0073] At this time, the first cylinder 5 drives the first connecting seat 82 to move, so that the extrusion seat 81 below the first connecting seat 82 moves accordingly. When the extrusion seat 81 contacts the mobile power battery, the extrusion seat 81 cannot move. At this time, the first connecting seat 82 continues to move, and then the first connecting seat 82 pushes the positioning component 83 to transmit. Under the action of the positioning component 83, the mobile power battery is pushed into position.

[0074] The positioning component 83 includes:

[0075] a sliding seat 831 slidably connected to the inner wall of the extrusion seat 81;

[0076] A rotating rod 832, one end of which is rotatably connected to the top end surface of the sliding seat 831;

[0077] a sliding rod 833 slidably connected to the inner wall of the rotating rod 832 ;

[0078] The rotating seat 834 is fixedly connected to one end of the sliding rod 833 away from the rotating rod 832 , and the rotating seat 834 is rotatably connected below the first connecting seat 82 .

[0079] A pressure spring 835 is sleeved on the outer peripheral wall of the sliding rod 833. The two ends of the pressure spring 835 are fixedly connected to the rotating rod 832 and the rotating seat 834 respectively. The pressure spring 835 cooperates to push the sliding seat 831 to move.

[0080] The bottom end surface of the sliding seat 831 is fixedly connected to the first positioning seat 836 . The first positioning seat 836 is attached to the bottom end surface of the extrusion seat 81 . The outer peripheral wall of the first positioning seat 836 is attached to the second positioning seat 837 .

[0081] A guide threaded rod 838 is slidably connected to the inner wall of the second positioning seat 837, and the guide threaded rod 838 is fixedly connected to the outer wall of the first positioning seat 836. The outer peripheral wall of the guide threaded rod 838 is threadedly connected with a fixing bolt, and the second positioning seat 837 is fixed to the first positioning seat 836 by the bolt. The first positioning seat 836 and the second positioning seat 837 position the mobile power battery.

[0082] It should be particularly emphasized that when the first connecting seat 82 pushes the positioning assembly 83 to rotate, the first connecting seat 82 drives the rotating seat 834 to move, and the rotating seat 834 drives the sliding rod 833 and the rotating rod 832 to rotate. Under the push of the rotating rod 832, the sliding seat 831 slides on the extrusion seat 81, and then under the movement of the sliding seat 831, the first positioning seat 836 and the second positioning seat 837 are driven to move. Under the push of multiple first positioning seats 836 and second positioning seats 837, the mobile power battery is pushed and positioned;

[0083] Furthermore, when the first positioning seat 836 and the second positioning seat 837 are in contact with the mobile power battery, the first connecting seat 82 moves, pushing the rotating seat 834 to move, so that the sliding rod 833 slides along the rotating rod 832, and the sliding rod 833 and the rotating rod 832 rotate at the same time. At the same time, the rotating seat 834 compresses the pressure spring 835, and under the rebound of the pressure spring 835, the sliding seat 831, the first positioning seat 836 and the second positioning seat 837 are pushed, so that the first positioning seat 836 and the second positioning seat 837 squeeze the mobile power battery to position the mobile power battery, and the squeezing force is small, which will not damage the mobile power battery shell.

[0084] Furthermore, when it is necessary to position mobile power batteries of different sizes, the second positioning seat 837 and the first positioning seat 836 are in a loose state by adjusting the tightness of the fixing bolts. The second positioning seat 837 is adjusted to slide along the guide thread rod 838 to change the position of the end of the second positioning seat 837 relative to the first positioning seat 836. The second positioning seat 837 and the first positioning seat 836 are adjusted to correspond to the size of the mobile power battery. Then, the first positioning seat 836 and the second positioning seat 837 are fixed by tightening the bolts. The same operation is performed on multiple first positioning seats 836 and second positioning seats 837 to facilitate the positioning of mobile power batteries of different sizes.

[0085] Example 2:

[0086] According to the attached Figure 1-11 As shown, it includes a detection platform 1, on which the following are provided:

[0087] The loading and unloading robot 2 is installed on the detection platform 1 and is used to suck the mobile power battery to the designated position;

[0088] A docking unit 3 is installed on the detection platform 1 and is used to transport mobile power batteries;

[0089] The mounting platform 4 is mounted on the detection platform 1. The first cylinder 5, the second cylinder 6 and the third cylinder 7 are mounted on the mounting platform 4.

[0090] A positioning unit 8 is installed below the mounting platform 4 and is connected to the output end of the first cylinder 5. The positioning unit 8 is used to position and pressure test the mobile power battery.

[0091] Specifically disclosed, when a random inspection of a mobile power battery is set, the processor sets the current inspection of the mobile power battery as a sampling inspection, and starts the first transmission platform 31, so that the battery processing platform 33 is transported along the track on the first transmission platform 31, and the mobile power battery on the battery processing platform 33 is transported to the bottom of the positioning unit 8. At this time, the processor controls the first cylinder 5 to drive the positioning unit 8 to move downward, so that the positioning unit 8 moves toward the mobile power battery;

[0092] Furthermore, at this time, the first cylinder 5 drives the first connecting seat 82 to move, so that the extrusion seat 81 below the first connecting seat 82 moves accordingly. When the extrusion seat 81 contacts the mobile power battery, the processor controls the first cylinder 5 to apply a specified pressure, pushing the first connecting seat 82 to generate a specified pressure on the extrusion seat 81 to perform a pressure test.

[0093] The test unit 9 is installed below the mounting platform 4 and is connected to the output ends of the second cylinder 6 and the third cylinder 7. The two test units 9 are used for voltage detection of the mobile power battery and charge and discharge test of the mobile power battery respectively.

[0094] Test unit 9 includes:

[0095] A charge and discharge tester 91 is located below the mounting platform 4. The charge and discharge tester 91 is an existing mature structure, model CT-3008-10V3A-A, and will not be described in detail in this application;

[0096] The second connecting base 92 has its top end surface mounted on the output ends of the corresponding second cylinder 6 and the corresponding third cylinder 7. The second connecting base 92 is located directly above the charge-discharge tester 91. The second connecting base 92 cooperates with the corresponding second cylinder 6 and the corresponding third cylinder 7 to drive the charge-discharge tester 91 to move.

[0097] The telescopic rod 93 has two ends fixedly connected to the charge and discharge tester 91 and the second connecting base 92 respectively;

[0098] The compression spring 94 is sleeved on the outer peripheral wall of the telescopic rod 93 , and both ends of the compression spring 94 are fixedly connected to the charge and discharge tester 91 and the second connecting seat 92 respectively.

[0099] Temperature monitors 95 are provided on both sides of the charge and discharge tester 91. The temperature monitors 95 are used to perform real-time temperature monitoring and alarm functions on the mobile power supply battery.

[0100] It should be particularly emphasized that after the mobile power battery is positioned, the first cylinder 5 drives the positioning unit 8 to move upward, and then the first positioning seat 836 and the second positioning seat 837 are separated from the mobile power battery. At this time, the battery processing platform 33 on the first transmission platform 31 is controlled to drive the mobile power battery to move below the second cylinder 6, and the second cylinder 6 is started to control the test unit 9 to move downward;

[0101] Furthermore, at this time, the second connecting seat 92 moves, and the charge and discharge tester 91 is driven to move along with it through the telescopic rod 93. When the charge and discharge tester 91 moves and contacts the mobile power battery, the charge and discharge tester 91 pushes the compression spring 94 to compress. Under the rebound of the compression spring 94, the charge and discharge tester 91 is pushed to contact the mobile power battery stably. At the same time, the positive and negative electrode interfaces on the charge and discharge tester 91 are plugged into the positive and negative electrode interfaces of the mobile power battery. The processor starts the charge and discharge tester 91 to measure the core parameters of the mobile power battery, such as open circuit voltage, internal resistance, capacity, and charge and discharge curve. Defective products are quickly screened out according to the set parameter thresholds, thereby simplifying the production inspection process.

[0102] It should be emphasized that after the mobile power battery pressure test is performed, the first transmission platform 31 is started, so that the battery processing platform 33 drives the mobile power battery to be under the loading and unloading robot 2, and the mobile power battery is adsorbed and placed on the battery processing platform 33 of the second transmission platform 32 by the loading and unloading robot 2;

[0103] Furthermore, under the action of the second transmission platform 32, the battery processing platform 33 drives the mobile power battery to move to the bottom of the third cylinder 7, and the processor controls the third cylinder 7 to start, and drives the control test unit 9 to move downward through the third cylinder 7, pushing the charge and discharge tester 91 to stably contact the mobile power battery. At the same time, the positive and negative pole interfaces on the charge and discharge tester 91 are plugged into the positive and negative pole interfaces of the mobile power battery, and the processor starts the charge and discharge tester 91 to perform charge and discharge tests on the mobile power battery to detect whether the charge and discharge data are normal.

[0104] Furthermore, when the mobile power battery is charging and discharging normally, the data is recorded, and the mobile power battery is removed to perform high and low temperature cycle tests, vibration tests, and drop tests. When the mobile power battery is charging and discharging abnormally, an abnormal alarm is issued and abnormal monitoring is performed manually.

[0105] Working principle: When testing the mobile power battery, the mobile power battery is first transferred. When the mobile power battery is moved to the testing platform 1, the processor controls the loading and unloading robot 2 to start. The loading and unloading robot 2 carries an identification camera, which identifies the mobile power battery through the camera. The camera on the loading and unloading robot 2 detects whether the mobile power battery is under the loading and unloading robot 2. The number of detection and identification times is set. If the identification and detection cannot be performed for multiple times, a fault warning is issued. The identification and detection can be set to a cyclic detection number as needed;

[0106] When the mobile power battery is detected by the camera on the loading and unloading robot 2, the robotic arm in the loading and unloading robot 2 is controlled to move, and the suction cup on the robotic arm is positioned directly above the mobile power battery to suck the mobile power battery, and then the robotic arm on the loading and unloading robot 2 places the mobile power battery on the battery processing part platform 33 of the first transmission platform 31;

[0107] At this time, by starting the first transport platform 31, the battery processing part platform 33 is transported along the track on the first transport platform 31, and the mobile power battery on the battery processing part platform 33 is transported to the bottom of the positioning unit 8. At this time, the processor controls the first cylinder 5 to drive the positioning unit 8 to move downward, so that the positioning unit 8 moves toward the mobile power battery;

[0108] At this time, the first cylinder 5 drives the first connecting seat 82 to move, so that the extrusion seat 81 below the first connecting seat 82 moves accordingly. When the extrusion seat 81 contacts the mobile power battery, the extrusion seat 81 cannot move. At this time, the first connecting seat 82 continues to move, and then the first connecting seat 82 pushes the positioning assembly 83 to transmit. Under the action of the positioning assembly 83, the mobile power battery is pushed into position;

[0109] When the first connecting seat 82 pushes the positioning assembly 83 to rotate, the first connecting seat 82 drives the rotating seat 834 to move, and the rotating seat 834 drives the sliding rod 833 and the rotating rod 832 to rotate. Under the push of the rotating rod 832, the sliding seat 831 slides on the extrusion seat 81, and then the movement of the sliding seat 831 drives the first positioning seat 836 and the second positioning seat 837 to move. Under the push of the multiple first positioning seats 836 and the second positioning seats 837, the mobile power battery is pushed and positioned;

[0110] When the first positioning seat 836 and the second positioning seat 837 are in contact with the mobile power battery, the first connecting seat 82 moves, pushing the rotating seat 834 to move, so that the sliding rod 833 slides along the rotating rod 832, and the sliding rod 833 and the rotating rod 832 rotate. At the same time, the rotating seat 834 compresses the pressure spring 835. Under the rebound of the pressure spring 835, the sliding seat 831, the first positioning seat 836 and the second positioning seat 837 are pushed, so that the first positioning seat 836 and the second positioning seat 837 squeeze the mobile power battery to position the mobile power battery, and the squeezing force is small, which will not damage the mobile power battery shell.

[0111] After the mobile power battery is positioned, the first cylinder 5 drives the positioning unit 8 to move upward, and then the first positioning seat 836 and the second positioning seat 837 are separated from the mobile power battery. At this time, the processing and control of the battery processing platform 33 on the first transmission platform 31 drives the mobile power battery to move below the second cylinder 6, and the second cylinder 6 is started to control the testing unit 9 to move downward;

[0112] At this time, the second connecting seat 92 moves, and the charge and discharge tester 91 is driven to move along with it through the telescopic rod 93. When the charge and discharge tester 91 moves and contacts the mobile power battery, the charge and discharge tester 91 pushes the compression spring 94 to compress. Under the rebound of the compression spring 94, the charge and discharge tester 91 is pushed to contact the mobile power battery stably. At the same time, the positive and negative electrode interfaces on the charge and discharge tester 91 are plugged into the positive and negative electrode interfaces of the mobile power battery. The processor starts the charge and discharge tester 91 to measure the core parameters of the mobile power battery, such as open circuit voltage, internal resistance, capacity, and charge and discharge curve. Defective products are quickly screened out according to the set parameter thresholds, thereby simplifying the production inspection process.

[0113] After the mobile power battery is tested and found to be qualified, the battery processing platform 33 on the first transmission platform 31 is used to drive the mobile power battery to reset, and then the loading and unloading robot 2 is used to absorb and transmit the mobile power battery, and a new mobile power battery is replaced for testing. After the unqualified mobile power battery is detected, it is collected and placed in a centralized manner for manual testing to determine the problem.

[0114] When a random inspection of mobile power batteries is set, the processor sets the current inspection of mobile power batteries as a sampling inspection, and starts the first transmission platform 31 so that the battery processing platform 33 is transported along the track on the first transmission platform 31, and the mobile power batteries on the battery processing platform 33 are transported to the bottom of the positioning unit 8. At this time, the processor controls the first cylinder 5 to drive the positioning unit 8 to move downward, so that the positioning unit 8 moves toward the mobile power batteries;

[0115] At this time, the first cylinder 5 drives the first connecting seat 82 to move, so that the extrusion seat 81 below the first connecting seat 82 moves accordingly. When the extrusion seat 81 contacts the mobile power battery, the processor controls the first cylinder 5 to apply a specified pressure, pushing the first connecting seat 82 to generate a specified pressure on the extrusion seat 81 to perform a pressure test. After the test is completed, the first transmission platform 31 is started, so that the battery processing platform 33 drives the mobile power battery to be under the loading and unloading robot 2, and the mobile power battery is adsorbed and placed on the battery processing platform 33 of the second transmission platform 32 by the loading and unloading robot 2;

[0116] Under the action of the second transmission platform 32, the battery processing platform 33 drives the mobile power battery to move to the bottom of the third cylinder 7, and the processor controls the third cylinder 7 to start, and drives the control test unit 9 to move downward through the third cylinder 7, pushing the charge and discharge tester 91 to stably contact the mobile power battery. At the same time, the positive and negative electrode interfaces on the charge and discharge tester 91 are plugged into the positive and negative electrode interfaces of the mobile power battery. The processor starts the charge and discharge tester 91, performs charge and discharge tests on the mobile power battery, and detects whether the charge and discharge data are normal.

[0117] When the mobile power battery is charging and discharging normally, the data is recorded and the mobile power battery is removed for high and low temperature cycle testing, vibration testing, and drop testing. When the mobile power battery is charging and discharging abnormally, an abnormal alarm is issued and manual abnormal monitoring is performed.
