Description

Technical Field

[0001] The present invention relates to the technical field of energy storage device production, and in particular to an impregnation method and device with controllable impregnation time. Background Art

[0002] Traditional energy storage device production typically utilizes an assembly line. After the element is placed in an aluminum shell, it flows through the assembly line into a liquid injection mechanism, which injects impregnation liquid into the aluminum shell to impregnate the element. Once the liquid injection is complete, the element enters an impregnated state. The impregnated element then passes through the assembly line into a beam-molding sealing mechanism for beam-molding sealing, completing the impregnation and packaging of the energy storage device. However, due to the fixed operation time of the assembly line—that is, the time the element remains on the assembly line after impregnation—the element's impregnation time cannot be controlled. Once the assembly line is designed, the element's impregnation time cannot be changed, and production must proceed according to the set impregnation time. Adjusting the impregnation time requires significant modifications to the production line. When a customer requests a change in the impregnation time for a batch of energy storage devices, the conventional production line cannot adjust the element's impregnation time in the aluminum shell, resulting in energy storage devices that fail to meet customer requirements. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an impregnation method with controllable impregnation time. When N shells impregnated with elements are sent into the buffer zone for waiting, the N shells first sent into the buffer zone are sent out of the buffer zone so that the buffer zone has enough waiting time for the shells impregnated with elements, thereby allowing the elements to obtain sufficient impregnation time. When the elements first sent into the buffer zone are fully impregnated, the N shells first sent into the buffer zone are sent out, and at the same time, N shells impregnated with elements are sent into the buffer zone so that the number of elements staying in the buffer zone remains consistent, thereby ensuring that the impregnation time of each element is the same; because the more shells stay in the buffer zone, the longer the shells stay in the transmission device, and vice versa; the fewer shells are sent into and out of the buffer zone each time, the longer the shells stay in the buffer zone, and vice versa. In this way, the time the shells stay in the buffer zone can be controlled by controlling the number of shells in the buffer zone or the number of shells sent into and out of the buffer zone each time, thereby meeting the function of adjusting the impregnation time of the elements in the aluminum shells at any time on the production line, thereby improving the consistency of the energy storage device and meeting the needs of users.

[0034] The present invention will be described in detail below with reference to the examples. The examples are only preferred embodiments of the present invention and are not intended to limit the present invention.

[0035] The present invention provides an impregnation method with controllable impregnation time, which comprises the following steps:

[0036] Step 1: Place the element into the shell filled with impregnation liquid for impregnation;

[0037] Step 2: N shells impregnated with elements are sent to a buffer for impregnation and wait for the impregnation time to complete. At the same time, step 3 is performed. The buffer is filled with multiple shells waiting for the impregnation time to complete in the order of the time of sending them to the buffer, where N ≥ 1 and N is an integer.

[0038] Step 3: Send the N shells sent into the buffer zone first out of the buffer zone, and encapsulate the N shells sent out of the buffer zone.

[0039] When N shells impregnated with elements are sent into the buffer zone for waiting, the first N shells sent into the buffer zone are sent out of the buffer zone so that the buffer zone has enough shells impregnated with elements, thereby allowing the elements to obtain sufficient impregnation time. When the elements sent into the buffer zone first are fully impregnated, the first N shells sent into the buffer zone are sent out, and at the same time, N shells impregnated with elements are sent into the buffer zone so that the number of elements staying in the buffer zone remains consistent, thereby ensuring that the impregnation time of each element is the same; because the more shells staying in the buffer zone, the longer the shells stay in the transmission device, and vice versa; the fewer shells sent into and out of the buffer zone each time, the longer the shells stay in the buffer zone, and vice versa. In this way, the time the shells stay in the buffer zone can be controlled by controlling the number of shells in the buffer zone or the number of shells sent into and out of the buffer zone each time, thereby meeting the function of adjusting the element impregnation time in the aluminum shell at any time on the production line, thereby improving the consistency of energy storage devices and meeting user needs.

[0040] Furthermore, the buffer zone is provided with a feeding buffer device, which includes a transmission device and a control device arranged on the transmission device. The transmission device can send N shells in and out at a time. The control device includes a blocking component and a positioning component arranged in front of the blocking component. The blocking component is used to block the transmission of all shells on the transmission device, and the positioning component is used to block the transmission of the N+1th shell on the transmission device and all shells behind it.

[0041] Furthermore, it also includes a feeding device and a discharging device, the feeding device is arranged at the feeding end of the transmission device and is used to feed M shells into the transmission device, and the discharging device is arranged at the discharging end of the transmission device and is used to feed M shells out of the transmission device.

[0042] Example 1:

[0043] Liquid injection impregnation generally requires three or more impregnations. The last impregnation is performed by injecting impregnation liquid into the aluminum shell to impregnate the element. In this embodiment, the element in the impregnated state refers to the last impregnation.

[0044] In this embodiment, 10 elements are placed in a shell filled with impregnation liquid for impregnation; the feeding device is a feeding robot, and the discharging device is a discharging robot. First, when the entire device starts working, the blocking component is raised, the positioning component is set to a positioning position and dropped for use, and 100 shells loaded with impregnated elements are fed into the transmission device into the buffer zone and blocked by the blocking component, so that the feeding buffer device is loaded with a sufficient number of shells, thereby allowing the elements to obtain sufficient impregnation time. Multiple shells are arranged in the buffer zone in order of feeding time. When the front element is fully impregnated, the entire system begins a reciprocating cycle. The positioning assembly then rises and blocks the 11th and all subsequent elements. The blocking assembly then drops, allowing the first 10 elements to be transported out of the buffer by the discharge robot and into the packaging process. After these elements are delivered, the blocking assembly rises and the positioning assembly drops, transporting the 11th and all subsequent elements to the blocking assembly and blocking them. Simultaneously, the infeed robot delivers the remaining 10 elements to the end of the buffer, completing a complete reciprocating cycle. The more elements remaining in the buffer, the longer they remain there, and vice versa. The fewer elements transported per time, the longer they remain there, and vice versa. This allows the time spent in the buffer to be controlled by either the number of elements in the buffer or the number of elements transported per time by the robot. This allows the impregnation time of the elements in the aluminum shell to be adjusted on the production line, improving the consistency of energy storage devices and meeting user needs.

[0045] In this embodiment, the number of shells in the buffer zone is 100, the number of shells transported each time by the feeding robot and the discharging robot is 10, and the processing interval of the subsequent process is 30S, that is, the time for the feeding robot and the discharging robot to transport the shell each time is 30S, then the element of each shell in the buffer zone is impregnated in the aluminum shell for 5 minutes; when the impregnation time needs to be changed to 10 minutes, it is only necessary to adjust the number of shells in the transfer buffer zone to 200. When the impregnation time needs to be changed to 1-10 minutes or any other time, it is sufficient to adjust the number of shells buffered in the buffer zone or the number of shells transported each time by the feeding robot and the discharging robot, so that the impregnation time of the element in the aluminum shell on the production line can be adjusted at any time.

[0046] An impregnation method with controllable impregnation time comprises the following steps:

[0047] Step 1: Place the housing into the carrier, and place the element into the housing filled with impregnation liquid for impregnation;

[0048] Step 2: Send M carriers loaded with impregnated elements into a buffer for impregnation and wait for the impregnation time to complete while executing step 3. The buffer is filled with multiple carriers waiting for the impregnation time to complete, arranged in the order of the time of delivery, where M ≥ 1, and M is an integer;

[0049] Step 3: Send the M carriers that are first sent into the buffer zone out of the buffer zone, and encapsulate the shells of the M carriers sent out of the buffer zone.

[0050] The following steps are also included:

[0051] Step 4: Send M empty carriers into the recirculation area, where multiple carriers are placed in the recirculation area in the order of the time of delivery;

[0052] Step 5: Send the M empty carriers that were first sent into the recirculation area out of the recirculation area;

[0053] Repeat steps 1 to 5.

[0054] Furthermore, the step 1 specifically includes:

[0055] Step 1.1: Place the housing into the carrier;

[0056] Step 1.2: injecting impregnation liquid into the shell;

[0057] Step 1.3: Place the element after secondary impregnation into the shell filled with impregnation liquid for impregnation.

[0058] The present invention also provides an impregnation device with controllable impregnation time, which includes a feeding buffer device, the feeding buffer device includes a transmission device and a control device arranged on the transmission device, the transmission device can send M carriers in and out at a time, the control device includes a blocking component and a positioning component arranged in front of the blocking component, the blocking component is used to block the transmission of all carriers on the transmission device, and the positioning component is used to block the transmission of the M+1th carrier on the transmission device and all carriers behind it.

[0059] Furthermore, it also includes a feeding device and a discharging device, the feeding device is arranged at the feeding end of the transmission device and is used to send M carriers into the transmission device, and the discharging device is arranged at the discharging end of the transmission device and is used to send M carriers out of the transmission device.

[0060] Furthermore, the blocking assembly includes a blocking block and a blocking cylinder for controlling the upward and downward movement of the blocking block, and the positioning assembly includes a positioning rod and a positioning cylinder for controlling the upward and downward movement of the positioning rod.

[0061] Furthermore, the control device also includes a lifting assembly for lifting or lowering all carriers on the transmission device, and the lifting assembly includes a lifting plate and a lifting cylinder that controls the up and down movement of the lifting plate.

[0062] Example 2:

[0063] See also Figures 1 to 4 Injection-type impregnation generally requires three or more impregnations. The last impregnation is performed by injecting the impregnation liquid into the aluminum shell to impregnate the element 102. In this embodiment, the element 102 in the impregnated state refers to the last impregnation, i.e., the third impregnation.

[0064] In this embodiment, the housing is placed in a carrier 101, an impregnation liquid is injected into the housing, and the element 102, after secondary impregnation, is placed in the housing containing the impregnation liquid for impregnation. The transmission device 1 comprises two conveyor belts, with the ends of the carrier 101 positioned on the two conveyor belts. The control device 2 includes a blocking assembly 21, a positioning assembly 22 positioned in front of the blocking assembly 21, and a lifting assembly 23 for raising and lowering all the carriers 101 on the transmission device 1. The lifting assembly 23 is positioned between the two conveyor belts and behind the blocking assembly 21, and has a groove formed in the lifting assembly 23 to avoid the positioning assembly 22. When the entire device starts working, the blocking component 21 is raised, the positioning component 22 is set to the positioning position and dropped for use, and the transmission device 1 sends 20 carriers 101 loaded with impregnated elements 102 into the transmission device 1 in the buffer zone 100 and is blocked by the blocking component 21. The carriers 101 are arranged in sequence according to the time of delivery so that the transmission device 1 is loaded with a sufficient number of carriers 101, thereby allowing the elements 102 to obtain sufficient impregnation time. At this time, the lifting component 23 is raised to lift all the carriers 101 to avoid damage caused by excessive friction of the transmission device 1 on the carriers 101. When the front element 102 is fully impregnated, the entire device starts a reciprocating cycle. At this time, the lifting component 23 falls and all the carriers 101 fall onto the conveyor belt, the positioning component 22 rises and blocks the transmission of the second carrier 101 and all the carriers 101 behind it, and then the blocking component 21 falls, so that the frontmost carrier 101 is sent out by the discharge device 4 and enters the packaging process; after the carrier 101 is sent out, the blocking component 21 rises, the positioning component 22 falls, the second carrier 101 and all the carriers 101 behind it are transmitted to the blocking component 21 and blocked, and at the same time, the feeding device 3 sends a carrier 101 to the end of the transmission device 1, and is driven by the conveyor belt close to all other carriers 101, the lifting component 23 rises to lift all the carriers 101 to avoid damage caused by excessive friction of the conveyor belt on the carrier 101, and now a complete reciprocating cycle is completed. The more carriers 101 that remain in the buffer zone 100, the longer they remain there, and vice versa. The fewer carriers 101 that are transported each time by the feed device 3 and the discharge device 4, the longer they remain in the buffer zone 100, and vice versa. Thus, the time a carrier 101 remains in the buffer zone 100 can be controlled by controlling the number of carriers 101 in the buffer zone 100 or the number of carriers 101 transported each time by the feed device 3 and the discharge device 4. This allows the time a carrier 101 remains in the buffer zone 100 to be adjusted at any time during the production line, thereby improving the consistency of the energy storage device and meeting user needs.

[0065] In this embodiment, the number of carriers 101 in the buffer zone 100 is 20, and the number of carriers 101 transported each time by the feeding device 3 and the discharging device 4 is 1, and the processing interval of the subsequent process is 30S, that is, the time for the feeding device 3 and the discharging device 4 to transport the carrier 101 each time is 30S, then the element 102 of each carrier 101 in the buffer zone 100 is impregnated in the aluminum shell for 10 minutes; when the impregnation time needs to be changed to 5 minutes, it is only necessary to adjust the number of carriers 101 in the buffer zone 100 to 10. When the impregnation time needs to be changed to 1-10 minutes or any other time, it is sufficient to adjust the number of carriers 101 buffered in the buffer zone 100 or the number of carriers 101 transported each time by the feeding device 3 and the discharging device 4, so that the impregnation time of the element 102 in the aluminum shell can be adjusted at any time on the production line.

[0066] The discharge device 4 delivers carriers 101 to the discharge conveyor 6 for packaging. After entering the packaging process, the shells on the carriers 101 are removed. The discharge conveyor 6 then delivers an empty carrier 101 to the reflow area 200, where multiple carriers 101 are arranged in order of their arrival. The empty carrier 101 that first entered the reflow area 200 is then conveyed out of the reflow area 200 and onto the feed conveyor 5. Shells are then placed into the empty carriers 101, and the impregnation liquid is then injected into the shells. After the second impregnation, the element 102 is then placed into the shells filled with the impregnation liquid for impregnation, and the cycle repeats.
