Description

Technical Field

[0001] The present invention relates to an interactive control system and an interactive control method between a stacker and a charging and discharging machine shelf. Background Art

[0002] The production process of lithium batteries is very complex and includes multiple processes. Formation is an important part that cannot be ignored, and it has a crucial impact on the performance of lithium batteries. Lithium battery formation is the first charging process of the battery after injection, which is completed by a charging and discharging machine. Generally, there are hundreds of charging and discharging machines installed on the shelves in the formation warehouse, and the stacker completes the transfer of batteries and pallets between the shelves and the logistics line. This process requires the stacker and the charging and discharging machine to be docked frequently. Figure 1 is a typical docking method. As can be seen from Figure 1 the stacker cannot directly interact with the charging and discharging machine shelf and needs to be transferred multiple times, resulting in a complex docking process between the stacker and the charging and discharging machine shelf, poor real-time performance, low efficiency, difficulty in coping with emergencies, and great inconvenience to equipment maintenance due to many links. Summary of the Invention

[0003] In order to solve the above problems, the present invention proposes an interactive control system and an interactive control method between a stacker and a charging and discharging machine shelf that directly interact through optical signals, have a simple docking, strong real-time performance, high efficiency, and convenient later maintenance.

[0004] The interactive control system between the stacker and the charging and discharging machine shelf of the present invention is characterized in that it includes a first optical transmission device and a second optical transmission device;

[0005] The charging and discharging machine shelf is arranged in the storage location. The shelf is a multi-row and multi-column frame structure, and a first optical transmission device is provided at the bottom of the front side of each column of the shelf;

[0006] The first optical transmission device is electrically connected to the charging and discharging machine. The first optical transmission device detects the current state of each layer in each column of the shelf, receives the target layer number optical signal sent by the second optical transmission device, and feeds back the actual layer number optical signal and the current state of each layer of the shelf to the second optical transmission device;

[0007] The second optical transmission device is arranged on the loading platform of the stacker, and the second optical transmission device is electrically connected to the stacker. The second optical transmission device is optically signal-interactively connected to the first optical transmission device. The second optical transmission device sends the target layer number optical signal to the first optical transmission device according to the instruction sent by the stacker, and feeds back the actual layer number optical signal and the current state of each layer sent by the first optical transmission device to the stacker for processing, so as to realize the optical signal interaction between the stacker and the shelf.

[0008] Further, the interactive control system further includes an alarm device, and the alarm device is electrically connected to the stacker crane.

[0009] An interactive control method according to the present invention is characterized by comprising:

[0010] Step 1: After the stacker crane moves to the target position, the stacker crane gives the target floor number and sends a target floor number optical signal to the first optical transmission device facing it on the shelf through the second optical transmission device;

[0011] Step 2: The first optical transmission device receives the target floor number optical signal sent by the second optical transmission device and feeds back an actual floor number optical signal of the shelf to the second optical transmission device;

[0012] Step 3: The second optical transmission device feeds back the actual floor number optical signal sent by the first optical transmission device to the stacker crane;

[0013] Step 4: The stacker crane compares the target floor number optical signal with the actual floor number optical signal. If they are different, it alarms and waits for manual processing. If they are the same and the stacker crane receives an allow signal from the shelf within the set time, the stacker crane operates;

[0014] Step 5: After the operation of the stacker crane ends, a completion signal is sent to the shelf, and the docking between the stacker crane and the shelf ends.

[0015] The beneficial effects of the present invention are as follows: The stacker crane can directly interact with each storage location of the charging and discharging machine through optical signals without transfer. The docking process is simple, has good real-time performance, high efficiency, can conveniently and quickly respond to emergencies, and because there are few docking links, it greatly facilitates the later maintenance of the equipment; moreover, the optical transmission device can send and receive multiple optical signals, and uses air as the signal medium, greatly simplifying the usage method.

[0030] The interactive control system of the stacker and the charging and discharging machine shelf described in the present invention includes a first optical transmission device 1 and a second optical transmission device 2;

[0031] The shelf 3 of the charging and discharging machine is arranged in the storage location, and the shelf 3 is a multi-row and multi-column frame structure; a first optical transmission device 1 is provided at the bottom of the front side of each column of the shelf 3;

[0032] The first optical transmission device 1 is electrically connected to the charging and discharging machine. The first optical transmission device 1 detects the current state of each layer in each column of the shelf, receives the target layer number optical signal sent from the second optical transmission device 2, and feeds back the actual layer number optical signal of the shelf 3 and the current state of each layer to the second optical transmission device 2;

[0033] The second optical transmission device 2 is arranged on the load platform 71 of the stacker 7, and the second optical transmission device 2 is electrically connected to the stacker 7. The second optical transmission device 2 is optically signal-interactively connected to the first optical transmission device 1. The second optical transmission device 2 sends the target layer number optical signal to the first optical transmission device 1 according to the instruction sent by the stacker 7, and feeds back the actual layer number optical signal sent by the first optical transmission device 1 and the current state of each layer to the stacker 7 for processing, so as to realize the optical signal interaction between the stacker 7 and the shelf 3.

[0034] In some embodiments of the present invention, the interactive control system further includes an alarm device 8, and the alarm device 8 is electrically connected to the stacker 7. During use, the stacker 7 compares the target floor number optical signal with the actual floor number optical signal. If they are different, the alarm device starts to alarm and waits for manual processing at the same time.

[0035] An interactive control method of the present invention includes:

[0036] Step 1: After the stacker 7 moves to the target position, the stacker 7 gives the target floor number and sends the target floor number optical signal to the first optical transmission device 1 corresponding to the bottom of the shelf 3 through the second optical transmission device 2.

[0037] Step 2: The first optical transmission device 1 receives the target floor number optical signal sent by the second optical transmission device 2 and feeds back the actual floor number optical signal of the shelf 3 to the second optical transmission device 2.

[0038] Step 3: The second optical transmission device 2 feeds back the actual floor number optical signal sent by the first optical transmission device 1 to the stacker 7.

[0039] Step 4: The stacker 7 compares the target floor number optical signal with the actual floor number optical signal. If they are different, it alarms and waits for manual processing. If they are the same and the stacker 7 receives the permission signal of the shelf 3 within the set time, the stacker 7 acts.

[0040] Step 5: After the stacker 7 finishes acting, it sends a completion signal to the shelf 3, and the docking between the stacker 7 and the shelf 3 ends.

[0041] The shelf 3 generally has no more than 12 floors, and 4 binary bits (Bits) can represent numerical values from 0 to 15. Therefore, 4 channels of signals of the optical transmission device can be used to represent the target floor number of the shelf. Considering the docking control signal at the same time, an optical transmission device with 8 channels of signals can be selected and installed on the stacker and the shelf respectively, so as to realize the interaction through this device.

[0042] The signal definitions of the optical transmission devices on the stacker side and the shelf side are shown in Table 1:

[0043] Table 1 Docking signal definitions

[0044]

[0045] Specifically, such as Figure 2As shown in the figure, the shelves 3 are successively the first-layer shelves 4, the second-layer shelves 5, the third-layer shelves 6, ... from bottom to top; a first optical transmission device 1 is provided at the bottom of each column of shelves.

The second optical transmission device 2 is electrically connected to the stacker 7, and the electrical signal of the second optical transmission device 2 can be connected to the stacker 7, so as to realize the optical signal interaction communication between the stacker 7 and the shelves 3.

[0046] The control and operation process using the interaction control system of the stacker and the charging and discharging machine shelves of the present invention is as follows:

[0047] S1 The stacker 7 moves to the target position, the stacker 7 gives the target layer number, and sends the target layer number optical signal to the first optical transmission device 1 opposite on the shelves 3 through the second optical transmission device 2;

[0048] S2 The first optical transmission device 1 receives the target layer number optical signal sent by the second optical transmission device 2 and feeds back the actual layer number optical signal of the shelves 3 to the second optical transmission device 2;

[0049] S3 The second optical transmission device 2 feeds back the actual layer number optical signal sent by the first optical transmission device 1 to the stacker 7;

[0050] S4 The stacker 7 compares the target layer number optical signal with the actual layer number optical signal. If they are different, it alarms and waits for manual processing. If they are the same, it proceeds to the next step;

[0051] S5 The stacker 7 sends a storage / retrieval request to the shelves 3 through the second optical transmission device 2. The shelves 3 select whether to give an "allow" signal according to the current state of the corresponding layer; if allowed, proceed to the next step; if the stacker does not receive the "allow" signal after exceeding the set time, an overtime alarm is issued;

[0052] S6 After the stacker 7 receives the "allow" signal, it starts to perform the storage / retrieval operation and sends an "in-execution" signal. When the corresponding storage location receives this signal, it cannot perform any actions to avoid collisions;
