Description

Technical Field

[0001] This invention relates, and more particularly, to a method for power transfer, tilting, stacking, and extrusion installation of an energy storage battery pack. Background Technology

[0002] In the assembly of energy storage square aluminum-cased battery packs, the individual square aluminum-cased cells must first be arranged and combined in a specific pattern according to the pack's structural design. Common methods used in the industry for producing energy storage square aluminum-cased battery packs include: Fully automated solution: Depending on the company's scale and production capacity requirements, significant costs are invested to achieve automated cell warehousing → automated robot cell picking → automated robot stacking → automated extrusion → automated fixing → achieving online automated post-processing completion. Manual solution: The assembly of energy storage square aluminum-cased battery packs can also be completed manually, i.e., manual feeding → manual picking → manual stacking → manual fixing → manual completion of the entire process.

[0003] Existing processes are incomplete. Some only involve extrusion, some require manual transplanting, some require manual tilting, some use power transplanting but lack a coherent process flow, and some only guarantee installation dimensions without controlling the extrusion pressure. Fully automated solutions offer excellent consistency and quality control, but the investment cost is too high. Manual solutions are difficult to control and guarantee consistency. In summary: they have some features but lack depth, while comprehensive and in-depth solutions are too expensive. Summary of the Invention

[0004] The purpose of this invention is to provide a method for power transfer, tilting, stacking, and extrusion installation of energy storage battery packs to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for power transfer, tilting, stacking, and extrusion installation of an energy storage battery pack includes the following steps:

[0007] Step 1: Lifting the battery pack fixture plate;

[0008] On a double-speed chain, the tooling plate needs to be lifted and the double-speed chain drive needs to move independently;

[0009] Step 2: Transfer the tooling plate from the double-speed chain to the stacker;

[0010] The tooling plate on the double-speed chain is automatically transferred to the stacker after the position sensor switch detects the tooling plate by the automatic transfer mechanism.

[0011] Step 3: Move the off-line stacker to the side of the double-speed chain;

[0012] The position type induction detects that the tool plate is lifted to the position of the speed chain, and the line outside the stacking machine automatically moves to the speed chain side to prepare to receive the tool plate on the speed chain.

[0013] Step 4, the stacking machine plate chain moves the tool plate;

[0014] The plate chain mechanism on the stacking machine sends a signal to the speed chain, and the plate chain of the speed chain transmits the tool plate to the plate chain of the stacking machine. The plate chain automatically transmits the tool plate to the installation position of the stacking machine.

[0015] Step 5, the whole stacking machine moves to the assembly position;

[0016] At the same time, the stacking machine carries the tool plate and moves to the installation position of the battery PACK;

[0017] Step 6, the stacking machine installs the plate to an inclination of 20 degrees;

[0018] In order to ensure that the battery cell is accurately stacked in the shell during the stacking process, the battery cell and the shell are tightly and completely attached, and the battery PACK is inclined by 20 degrees during the stacking process. The inclination process is realized by the lifting cylinder on the stacking machine, which inclines the bearing plate of the tool plate as a whole, ensuring the inclination angle and safety.

[0019] Step 7, stack and assemble the battery PACK;

[0020] Under the inclination angle condition of the stacking machine, start manual stacking of the battery cell to assemble the PACK;

[0021] Step 8, pre-fix the battery PACK;

[0022] The pre-fixing of the battery PACK is realized by the screw fixing method, only the screw is locked, and no tightening is required.

[0023] Step 9, the cylinder extrudes the battery PACK;

[0024] After stacking, in order to ensure that the stacking size meets the design size and ensure the extrusion state of the battery cell, the cylinder is used for extrusion. The cylinder carries a pressure sensor and a displacement sensor, which detects whether the stacked battery PACK meets the technical requirements through the set size and pressure upper and lower limits;

[0025] Step 10, extrusion size detection;

[0026] After the extrusion cylinder is extruded to the position, the displacement sensor carried by the pressure head detects the extrusion displacement, calculates the difference between the extrusion size and the product size, and alarms when the size cannot reach the set size.

[0027] Step 11, extrusion pressure sensing;

[0028] After the extrusion cylinder is extruded in place, the pressure sensor carried by the pressure head detects the extrusion pressure after the battery PACK is extruded, which is used to control the problem of preventing the battery cell from being excessively extruded or insufficiently extruded. When the battery cell expands more than the design requirement of the battery PACK, the pressure sensor alarms and stops the extrusion action. When the extrusion pressure does not meet the design requirement, it indicates that the size of the battery cell is small, and an alarm is given for analysis.

[0029] Step 12, fix the battery PACK;

[0030] Tilt to the horizontal state, lock and fix the PACK according to the fixed torque value;

[0031] Step 13, the stacking machine is transplanted to the speed chain;

[0032] After the above actions are completed, the stacking machine is transplanted to the speed chain main body by manually controlling the transplantation button on the stacking machine;

[0033] Step 14, the plate chain transplantation tool plate on the stacking machine;

[0034] After the speed chain senses the position signal of the stacking machine, the plate chain of the stacking machine transplants the tool plate with the battery PACK to the transplantation mechanism of the speed chain;

[0035] Step 15, the battery PACK is put into the speed chain circulation.

[0036] Compared with the prior art, the present application has the following advantages: guaranteeing the consistency of the assembly process of the energy storage battery PACK, and guaranteeing the stability of the key process of the energy storage battery PACK assembly process.

[0037] Constant parameter control is performed on the key process control, such as the outer dimension of the square aluminum shell battery PACK after stacking, and the extrusion pressure when the control outer dimension after stacking is controlled. After the total weight of the energy storage battery PACK exceeds 100 kg after assembly, the operation of moving and transplanting is required. Interlocking function is set between processes, that is, the next process cannot be executed when the current process is not completed, so as to ensure that there is no security risk caused by process confusion and errors due to incorrect operation.

[0041] Step 1, battery PACK tool plate jacking;

[0042] On the speed chain, the tooling plate needs to be jacked up and driven independently from the speed chain;

[0043] Step 2, the plate chain of the speed chain moves the tooling plate to the stacking machine;

[0044] The tooling plate on the speed chain is moved to the stacking machine by the automatic moving mechanism, and the position sensing switch senses the tooling plate and automatically moves the tooling plate to the stacking machine;

[0045] Step 3, the off-line stacking machine moves to the side of the speed chain;

[0052] Because the energy storage cell is heavy, taking a 280Ah energy storage power battery as an example, the single weight is 5.4kg. In order to ensure that the cell is accurately stacked in the shell during the stacking process, the cell and the shell are tightly and completely attached to the battery PACK during the stacking process. The whole inclination angle is 20 degrees. The inclination process is achieved by the jacking cylinder on the stacking machine, which inclines the bearing plate of the tooling plate as a whole, ensuring the inclination angle and safety;

[0056] The pre-fixing of the battery PACK is achieved by the screw rod fixing method, which only locks the screw rod without tightening;

[0057] Step 9, the cylinder extrudes the battery PACK;

[0058] After the stacking is completed, in order to ensure that the stacking size meets the design size and ensure the extrusion state of the battery cell, a cylinder is used for extrusion, the cylinder carries a pressure sensor and a displacement sensor, and whether the stacked battery PACK meets the technical requirements is detected through the set size and pressure upper and lower limits;

[0059] Step 10, extrusion size detection;

[0060] After the extrusion cylinder is extruded to the position, the displacement sensor carried by the pressure head is used to detect the extrusion displacement, the difference between the extrusion size and the product size is calculated, and when the size cannot reach the set size, an alarm is given;

[0061] Step 11, extrusion pressure sensing;

[0062] After the extrusion cylinder is extruded to the position, the pressure sensor carried by the pressure head is used to detect the extrusion pressure after the battery PACK is extruded, which is used to control the problem of excessive extrusion or insufficient extrusion of the battery cell, when the battery cell expansion exceeds the design requirement of the battery PACK, the pressure sensor alarms and stops the extrusion action, when the extrusion pressure cannot meet the design requirement, it indicates that the size of the battery cell is small, and an alarm is given for analysis;

[0063] Step 12, fixing the battery PACK;

[0064] Tilt to the horizontal state, lock and fix the PACK according to the fixed torque value;

[0065] Step 13, moving the stacking machine to the speed chain;

[0066] After the above actions are completed, the manual control of the moving button on the stacking machine is used to move the stacking machine to the speed chain main body;

[0067] Step 14, the plate chain moving tool plate on the stacking machine;

[0068] After the speed chain senses the position signal of the stacking machine, the plate chain of the stacking machine moves the tool plate with the battery PACK to the moving mechanism of the speed chain;

[0069] Step 15, the battery PACK enters the speed chain circulation.
