Description

Technical Field

[0001] The present application relates to the field of battery production technology, and in particular to a battery cell transporting device. Background Art

[0002] The battery cell is formed by cyclically stacking the separator and the electrode. After the separator and the electrode are cyclically stacked, the battery cell needs to be transported to the subsequent fixing process production line by the battery cell handling equipment to complete the fixing of the separator and the electrode.

[0003] During transportation, since the diaphragm and electrode are not fixed together, the diaphragm and electrode on the lower layer are prone to drooping due to their own gravity, and the diaphragm and electrode on the upper layer may be lifted up by the airflow during transportation, which may cause wrinkles on the diaphragm and electrode, ultimately affecting the quality of the battery cell. Utility Model Content

[0004] The present application proposes a battery cell transport device for preventing diaphragms and pole pieces from wrinkling during transport.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] During the process of transporting battery cells using the battery cell transporting equipment provided by the present application, the first air pipe arranged above the upper clamp blows air to the diaphragm and electrode sheets on the upper layer through multiple blowing holes, so that the diaphragm and electrode sheets are flattened by the airflow to avoid being lifted up by the airflow generated by the movement; the second air pipe arranged below the lower clamp blows air to the diaphragm and electrode sheets on the lower layer through multiple blowing holes to offset the influence of the airflow generated by the gravity or movement of the diaphragm and electrode sheets on the lower layer, avoid wrinkles on the diaphragm and electrode sheets, and reduce the probability of quality problems of the battery cells due to the transport process.

[0008] In some embodiments, the blowing assembly also includes a first guide plate and a second guide plate; the first guide plate is fixed on the first air pipe, and the multiple blowing holes on the first air pipe are facing the first guide plate, and the first guide plate is used to guide the direction of the airflow blown out of the first air pipe; the second guide plate is fixed on the second air pipe, and the multiple blowing holes on the second air pipe are facing the second guide plate, and the second guide plate is used to guide the direction of the airflow blown out of the second air pipe.

[0009] In the above-mentioned implementation process, by respectively setting corresponding first guide plates and second guide plates on the first air pipe and the second air pipe, the airflow at the grabbing assembly can be effectively guided so that the blown gas flows in the direction guided by the guide plates, thereby overcoming the influence of the airflow on the diaphragm and electrode during transportation, and the problem of the lower diaphragm and electrode sagging due to the influence of gravity.

[0010] In some embodiments, the deflector includes a plate body and at least two air pipe connectors, each of which is secured to one side of the plate body. The air pipe connectors are provided with circular holes having a diameter greater than the outer diameter of the air pipes. In this embodiment, the air pipes are combined with the deflector body via the air pipe connectors to form an air blowing assembly.

[0011] In some embodiments, at least two threaded holes are provided on the plate body, and one threaded hole is provided on one side of the trachea connector; after being fixed, the threaded hole on the trachea connector is aligned with the threaded hole on the plate body.

[0012] In some embodiments, securing the deflector plate to the air pipe includes: after the air pipe passes through at least two air pipe connectors, screwing a bolt through at least two threaded holes in the plate body and threaded holes in at least two air pipe connectors until the bolt presses against the air pipe. In this embodiment, the bolt is tightened through the threaded holes connecting the deflector plate to the air pipe, thereby pressing against the air pipe, thereby securing the air pipe and ensuring the guiding effect of the deflector plate.

[0013] In some embodiments, after the air pipe passes through at least two air pipe connectors, the plate body is rotated around the air pipe to a predetermined angle. In this embodiment, after the air pipe passes through at least two air pipe connectors, the plate body can be rotated until it reaches a desired angle to adapt to the airflow direction required by battery cells of different sizes.

[0014] In some embodiments, the edges of the guide plate are chamfered.

[0029] The present application proposes a battery cell handling device, comprising a gripping assembly and a blowing assembly. The gripping assembly comprises an upper jaw and a lower jaw, and the blowing assembly comprises a first air pipe and a second air pipe, both of which are provided with a plurality of blowing holes. The first air pipe is provided above the upper jaw, and the second air pipe is provided below the lower jaw. The first air pipe is used to blow air toward the upper jaw during operation, and the second air pipe is used to blow air toward the lower jaw during operation. Thus, in the process of transporting a battery cell using the battery cell handling device provided by the present application, the first air pipe provided above the upper jaw blows air toward the diaphragm and electrode sheet located on the upper layer through the plurality of blowing holes, so that the diaphragm and electrode sheet are flattened by the airflow, thereby preventing them from being lifted up by the airflow generated by the movement. The second air pipe provided below the lower jaw blows air toward the diaphragm and electrode sheet located on the lower layer through the plurality of blowing holes, thereby offsetting the influence of the airflow generated by the gravity or movement of the diaphragm and electrode sheet on the lower layer, thereby preventing the diaphragm and electrode sheet from wrinkling, and reducing the probability of quality problems occurring during the handling process of the battery cell.

[0030] In some embodiments, Figure 1 A structural schematic diagram of a battery cell handling device is shown, wherein the battery cell handling device 100 includes a grabbing assembly 110 and a blowing assembly 120; the grabbing assembly 110 includes an upper clamping jaw 111 and a lower clamping jaw 112, and the blowing assembly 120 includes a first air pipe 121 and a second air pipe 122, and a plurality of blowing holes are provided on the air pipe.

[0031] For example, the air pipe may be made of metal materials such as copper, stainless steel, etc., or may be made of non-metal materials such as plastic or rubber.

[0032] The first air pipe 121 is provided above the upper clamping jaw 111 and is used to blow air toward the upper clamping jaw during operation. The second air pipe 122 is provided below the lower clamping jaw 112 and is used to blow air toward the lower clamping jaw during operation.

[0033] As a possible application example, the upper jaw 111 and the lower jaw 112 included in the grasping assembly 110 are controlled to open by the cylinder on the battery cell transporting equipment, and the upper jaw 111 is moved to the top of the battery cell on which the diaphragm and electrode are cyclically stacked, and the lower jaw 112 is moved to the bottom of the battery cell on which the diaphragm and electrode are cyclically stacked, and the upper jaw 111 and the lower jaw 112 are further controlled to close to complete the grasping of the battery cell, and air is blown to the upper diaphragm and electrode of the battery cell through the first air pipe 121, and air is blown to the lower diaphragm and electrode of the battery cell through the second air pipe 122, and the grasped battery cell is transported to the subsequent fixing process for fixing the diaphragm and electrode.

[0034] In some embodiments, in order to make the gas blown out of the air pipe blow more stably to the upper diaphragm and the electrode, as well as the lower diaphragm and the electrode, as shown in FIG. Figure 2As shown, in the battery cell transporting equipment 100 provided in the embodiment of the present application, the blowing assembly 120 further includes a first guide plate 123 and a second guide plate 124 .

[0035] The first guide plate 123 is fixed to the first air pipe 121, and the second guide plate 124 is fixed to the second air pipe 122. The multiple air holes on the first air pipe 121 face the first guide plate 123, and the first guide plate 123 is used to guide the direction of the airflow blown out of the first air pipe 121. The multiple air holes on the second air pipe 122 face the second guide plate 124, and the second guide plate 124 is used to guide the direction of the airflow blown out of the second air pipe 122.

[0036] It can be understood that by respectively setting corresponding first guide plates 123 and second guide plates 124 on the first air pipe 121 and the second air pipe 122, the airflow at the grabbing assembly 110 can be effectively guided so that the blown gas flows in the direction guided by the guide plates, thereby overcoming the influence of the airflow on the diaphragm and the electrode during transportation, and the problem of the lower diaphragm and the electrode sagging due to the influence of gravity.

[0037] In addition, the added guide plate can also stabilize the air pressure, reduce noise and protect the air pipe, which helps to improve the stability and reliability of the battery cell handling equipment 100, reduce the equipment failure rate and extend the service life of the equipment.

[0038] Among them, during the operation of the battery cell handling equipment 100, the opening and closing actions of the upper clamping jaw 111 and the lower clamping jaw 112 of the grasping component 110 and the rapid flow of gas may cause local air pressure instability. By adding a guide plate, the air pressure can be balanced to ensure that the grasping component 110 operates in a stable air pressure environment, thereby improving the clamping stability and accuracy of the clamping jaws; when the gas is blown to the battery cell grasped by the grasping component 110 through the guide plate, due to the guiding effect of the guide plate, the flow path of the gas is smoother, reducing the occurrence of turbulence and eddy currents, thereby reducing the noise level; when the grasping component 110 moves at high speed or clamps heavy objects, it may generate a large impact force or vibration, and adding a guide plate can buffer these impact forces and reduce the risk of damage to the air pipe due to excessive force.

[0039] In some embodiments, Figure 3 The schematic diagram of the structure of a guide plate 30 is shown. The guide plate 30 can be the first guide plate 123 or the second guide plate 124 . The guide plate 30 includes a plate body 31 and at least two air pipe connectors 32 .

[0040] Exemplarily, the plate 31 and the air pipe connector 32 may be made of metal materials such as copper, stainless steel, etc., or may be made of non-metal materials such as plastic.

[0041] At least two trachea connectors 32 are fixed on one side of the plate body 31 . The trachea connectors 32 are provided with circular holes, the diameter of which is larger than the outer diameter of the trachea.

[0042] For example, when the plate body 31 and the trachea connector 32 are made of metal, the trachea connector 32 and the plate body 31 can be fixed by welding. When the plate body 31 and the trachea connector 32 are made of non-metallic materials, the trachea connector 32 and the plate body 31 can be fixed by glue.

[0043] In some embodiments, in order to ensure that the guide plate 30 guides the gas blown out of the trachea, the trachea needs to be clamped and fixed to the guide plate. In the guide plate 30 provided in the embodiment of the present application, at least two threaded holes are provided on the plate body 31, and a threaded hole is provided on one side of the trachea connector 32. After aligning the threaded hole of the trachea connector 32 with a threaded hole on the plate body 31, it is fixed.

[0044] The size of the threaded hole provided on the plate body 31 is the same as the size of the threaded hole provided on the trachea connector 32 , for example, both are 3 mm, 4 mm, etc.

[0045] Based on the guide plate 30 shown in the above embodiment, after the air pipe passes through at least two air pipe connectors 32, the bolts are screwed into at least two threaded holes of the plate body 31 and the threaded holes on at least two air pipe connectors 32 until the bolts press against the air pipe, thereby completing the fixation of the air pipe and the guide plate.

[0046] In some embodiments, when the battery cell transporting equipment 100 transports battery cells of different sizes, it may be necessary to adjust the direction of the guide plate 30. At this time, after the air pipe passes through at least two air pipe connectors 32 of the guide plate 30, the plate body 31 is rotated around the air pipe to a preset angle, and then the bolts are screwed into at least two threaded holes of the plate body 31 and the threaded holes on at least two air pipe connectors 32 until the bolts press against the air pipe to correctly guide the direction of the air flow blown out of the first air pipe 121 and the second air pipe 122.

[0047] In some embodiments, the edges of the guide plate 30 are chamfered to improve the safety of the working environment.

[0048] In some embodiments, the blowing assembly 120 also includes a blowing device, which is connected to the first air pipe and the second air pipe through air flow channels. The gas blown out during the operation of the blowing device enters the air flow channel and is ejected from the multiple blowing holes of the first air pipe and the multiple blowing holes of the second air pipe.

[0049] Optionally, the blowing assembly 120 includes two blowing devices, which correspond to the first air pipe and the second air pipe respectively. In this way, by independently setting the blowing devices, different wind speeds can be blown out of the two air pipes, thereby independently controlling the upper and lower sides of the battery cell according to different requirements to ensure the quality of the battery cell.

[0050] In some embodiments, as Figure 4 As shown, the lower side of the upper clamping jaw 111 is attached with a first buffer pad 41 , and the upper side of the lower clamping jaw 112 is attached with a second buffer pad 42 to avoid injury from clamping the battery cell.

[0051] The first buffer pad 41 and the second buffer pad 42 can be made of the same material or different materials, such as plastic, rubber, etc.

[0052] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
