Description

Technical Field

[0001] The utility model relates to the field of lithium battery production, in particular to a handling device and a PACK testing system. Background Art

[0002] In recent years, the dual carbon policy and the downward trend of battery costs will drive the electrochemical energy storage market to high growth. In order to develop better energy storage products, we need to understand the battery's capacity, internal resistance, voltage characteristics, rate characteristics, temperature characteristics, cycle life, energy density and other important parameters through testing. These parameters are needed to prove whether the tested battery has achieved the original design goals, and these parameters are also needed to achieve better management and control during the use of the battery.

[0003] When testing, it needs to be placed inside a walk-in high and low temperature cycle test device to complete the test. The internal cavity of the test environment equipment has a certain height, and the battery pack (PACK) itself is large in size and weighs about 0.5T. During the test, the pack needs to be moved from the pallet into the cavity, and after the test is completed, it needs to be moved out. For projects with a short test cycle, it needs to be put in and taken out frequently.

[0004] At present, the transportation of PACK requires manual handling, which is inefficient and prone to safety hazards. At the same time, when testing, the PACK is placed on the test rack, and the test rack and PACK cannot be fixed in position, which may cause the battery rack to shift and the PACK to slide, resulting in inaccurate test results and low test efficiency.

[0005] The above problems need to be solved urgently. Utility Model Content

These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0036] Example

[0037] See also Figure 1-Figure 3 This embodiment provides a transport device for PACK400, including: a transport mechanism 100, a clamping mechanism 200 and a lifting mechanism 300; the clamping mechanism 200 is fixedly arranged on the top surface of the transport mechanism 100 through the lifting mechanism 300. By setting the transport mechanism 100, the clamping mechanism 200 and the lifting mechanism 300, the PACK400 can be taken and placed, which reduces labor costs and improves safety during the transport process.

[0038] In specific use, the clamping mechanism 200 is first sent to both sides of the PACK 400 by the lifting mechanism 300. After the clamping is completed, the PACK 400 is lifted by the lifting mechanism 300, and then the PACK 400 is taken out by the transport mechanism 100, and then the PACK 400 is placed on the transport mechanism 100 by the lifting mechanism 300. The process of placing the material is opposite to the process of taking the material, and the specific process is not described in this embodiment.

[0039] The specific structure of the clamping mechanism 200 is described below:

[0040] In this embodiment, the clamping mechanism 200 includes: a connecting rod 210 and two pick-and-place arms 220; the connecting rod 210 is fixedly disposed on the lifting mechanism 300; the two pick-and-place arms 220 are adjustably disposed on the connecting rod 210 and are disposed opposite to each other.

[0041] Specifically, the two pick-and-place arms 220 are slidably disposed on the connecting rod 210 , and the distance between the two pick-and-place arms 220 is adjusted according to the width of the PACK 400 , thereby adapting to the clamping requirements of PACK 400 of different sizes.

[0042] Optionally, the pick-and-place arm 220 is provided with a buckle. After the pick-and-place arm 220 completes clamping the PACK 400 , the pick-and-place arm 220 and the connecting rod 210 are fixed by the buckle, thereby preventing the pick-and-place arm 220 from sliding.

[0043] In this embodiment, at least one electromagnetic sheet 221 is disposed on the inner side of the pick-and-place arm 220; the electromagnetic sheet 221 is adapted to be adsorbed on the side of the PACK 400 when powered on, so as to complete the grabbing of the PACK 400. Specifically, a control switch for controlling the power on of the electromagnetic sheet 221 is disposed at the handrail 140 of the transport mechanism 100. It should be noted that the side of the shell of the PACK 400 is made of magnetic material.

[0044] In order to prevent the electromagnetic sheet 221 from scratching the housing of the PACK 400, in this embodiment, a flexible protective layer is provided on the contact surface between the electromagnetic sheet 221 and the PACK 400. Specifically, the flexible protective layer is made of rubber.

[0045] In order to improve the clamping ability of PACK400, at least one spring ejector pin 222 is further provided on the inner side of the pick-and-place arm 220. The spring ejector pin 222 strengthens the clamping ability of PACK400 and improves the stability of clamping.

[0046] In order to prevent the spring pin 222 from scratching the housing of the PACK 400 , in this embodiment, a flexible protective layer is provided on the contact surface between the spring pin 222 and the PACK 400 .

[0047] In order to send PACK400 to the high and low temperature environment box: in this embodiment, the pick-and-place arm 220 includes a fixed arm 223 and a sliding arm 224; the fixed arm 223 and the sliding arm 224 are slidably arranged. Among them, at least two sliders 2231 are horizontally arranged on the upper edge of the fixed arm 223; the sliding arm 224 is provided with a slide rail 2241 at the corresponding position of the slider 2231; the slide rail 2241 is embedded in the slider 2231. After the transport mechanism 100 transports PACK400 to the high and low temperature environment box, the lifting mechanism 300 lifts PACK400, and then pushes the sliding arm 224 to slide, and sends PACK400 to the test rack of the high and low temperature environment box, and fixes PACK400 by the sliding arm 224 to prevent PACK400 from sliding off the test rack. After the test is completed, the sliding arm 224 is pulled to take the PACK 400 out of the high and low temperature environment box, and then the PACK 400 is placed on the transportation mechanism 100 through the lifting mechanism 300 .

[0048] It should be noted that the sliding arm 224 can be pushed manually, or can be driven by a push cylinder or a push motor.

[0049] In this embodiment, the lifting structure is a jack. In other embodiments, the lifting mechanism 300 may use a pushing cylinder or a pushing motor.

[0050] In this embodiment, the transport mechanism 100 includes: a frame body 110, a universal wheel 120 and at least two rotating wheels 130; the universal wheel 120 and the at least two rotating wheels 130 are respectively arranged at the front and rear ends of the frame body 110. By arranging the universal wheel 120, the frame body 110 can turn, and by the cooperation of the rotating wheel 130 and the universal wheel 120, the frame body 110 can run forward or backward.

[0051] In this embodiment, a handrail 140 is further provided on the frame body 110 so as to push the frame body 110 .

[0052] This embodiment also passes a PACK400 testing system, including: a high and low temperature environment chamber, a PACK400 to be tested, and a transport device for PACK400 as described above; the PACK400 transport device is suitable for transporting the PACK400 to be tested to the high and low temperature environment chamber for testing.

[0053] In summary, this embodiment provides a transport device for PACK400, which can be used to pick up and place PACK400 by setting a transport mechanism 100, a clamping mechanism 200, and a lifting mechanism 300, thereby reducing labor costs and improving safety during transport. At the same time, the pick-up and place arm 220 of the clamping mechanism 200 is provided with a slide rail 2241 and a slider 2231, so that PACK400 can be sent to a high and low temperature environment box for testing, and PACK400 can be fixed during testing to prevent PACK400 from slipping.
