Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery piece processing, in particular to a battery piece carrying method, a purification table and a passivation device. BACKGROUND

[0002] With the increasing demand for battery piece conversion efficiency in the photovoltaic industry, it is difficult to meet market demand by simply improving the efficiency of the whole battery. Through edge passivation coating of the cut pieces (such as half pieces, three-piece batteries, and four-piece batteries), it has become a key technology path to effectively improve the power generation efficiency of the assembly. In this process, the purification table, as the core module of the ALD device, is responsible for the clean transmission, positioning and process scheduling of the battery pieces between the reaction chamber and the external environment, and its performance directly determines the yield, yield and cost of the coating process.

[0003] However, the edge passivation device purification table on the market has obvious shortcomings in dealing with the high yield and high precision coating demand of the piece battery. First, some devices use multi-joint flexible robots for box carrying in pursuit of flexibility, which is flexible in action but leads to high equipment cost and large space occupation. Due to the limitation of the structure, the number of boat cooling temporary storage stations is small, which cannot meet the high yield demand of continuous production. Second, the traditional purification table material carrying method is relatively single, and cannot realize the coordinated carrying and efficient circulation of the battery piece box and the process boat, and cannot be seamlessly connected with the special automatic feeding and discharging equipment of the piece battery. More importantly, the existing method generally lacks consideration of the special process requirements of the piece battery, and cannot solve the key problem that the cutting surface of the box needs to correspond to the airflow channel (air channel) in the boat when the box is loaded into the process boat, thereby affecting the uniformity of the process gas distribution and ultimately restricting the improvement of the passivation coating effect.

[0004] Therefore, there is an urgent need in the art for an innovative battery piece carrying method to realize efficient transfer of piece battery boxes and carrier boats and meet the process requirements of the cutting surface corresponding to the airflow direction to support high-quality edge passivation coating production.

DETAILED DESCRIPTION

[0065] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0066] The present application provides a battery piece carrying method for solar battery pieces, especially for edge passivation coating of split battery pieces, a purification table for implementing the method and a passivation device comprising the purification table. The technical solution aims to solve the problems of complex battery piece carrying operation, low efficiency, high cost and difficulty in meeting process alignment requirements in the prior art.

[0067] As shown in Figure 1 , 2 , specifically, the battery piece carrying method comprises:

[0068] A mapping relationship between the material box position on the carrying plate 400 and the target row and column position in the piece carrying boat 300 is established in advance, i.e. each material box position on the carrying plate 400 corresponds to a specific target row and column position in the piece carrying boat 300;

[0069] The empty carrier plate 400 is conveyed to the loading position, and the boxes 200 containing unprocessed battery pieces 190 are placed on the carrier plate 400 in a preset orientation rule based on the air channel layout of the carrier boat 300, so that after each box 200 is carried into the carrier boat 300, the cut surface of the unprocessed battery piece 190 in the box 200 faces the air channel of the carrier boat 300. For example, for two-split battery pieces, three-split battery pieces, or four-split battery pieces, the boxes 200 on the carrier plate 400 are placed in specific areas (such as the upper left area ①, the upper right area ②, the lower left area ③, and the lower right area ④) of the carrier plate 400 according to the number of single-box rows (such as three rows or four rows) of the carrier boat 300 where they are to be placed and the unified lateral orientation of the cut surface of the battery piece, and a mapping relationship with the corresponding rows in the boat is established.

[0070] The carrier plate 400 carrying the boxes 200 placed in the orientation is conveyed to the crane docking position 111, and an empty carrier boat 300 is moved to the docking boat position 600 aligned with the crane docking position.

[0071] The crane 120 carries each box 200 on the carrier plate 400 to the corresponding target row-column position of the carrier boat 300 through its linear motion in the horizontal and / or vertical plane according to the pre-established mapping relationship.

[0072] This design establishes a mapping relationship of the carrying position and controls the orientation of the battery piece, and only simple linear motion is required to ensure the alignment of the cut surface of the battery piece with the process airflow direction, so that the process gas can flow uniformly and smoothly in the boat and contact all the edges of the battery piece, ensuring the uniformity and consistency of the edge passivation film, thereby significantly improving the quality of the battery piece. Moreover, the crane 120 only needs to perform efficient linear motion according to the preset fixed path to complete the carrying, replacing the multi-joint flexible robot used in the traditional carrying method, improving the reliability of the equipment while reducing the manufacturing cost.

[0073] As an optimization, the number of boxes 200 placed on the carrier plate 400 is the same as the number of single-box rows of the carrier boat 300, and all the boxes 200 on each carrier plate 400 can exactly fill a column of the carrier boat 300 after being carried. When the carrier plate 400 is conveyed by the conveying line 110 to the crane docking position, the crane 120 will carry and place all the boxes 200 on the carrier plate 400 according to their respective target rows and columns to the corresponding single column of the carrier boat 300 according to the pre-established mapping relationship. Due to the matching number and preset position, these boxes 200 can fill the column of the carrier boat 300, and the cut surface of the battery piece in each box 200 is also precisely aligned with the air channel in the boat, simplifying the loading logic of the box 200 and improving the carrying efficiency.

[0074] For ease of understanding, some application examples of the present application are described below.

[0075] The middle of the carrier boat 300 is provided with two air channels, and the carrier plate 400 is provided with four placement areas in a rectangular distribution, which are the upper left area ①, the upper right area ②, the lower left area ③ and the lower right area ④, respectively.

[0076] As shown in FIG. 3, when the unprocessed battery piece 190 is a two-split battery piece and the single magazine position of the carrier boat 300 is three (the first row A to the third row C arranged from bottom to top), the upper left area ①, the upper right area ② and the lower left area ③ of the carrier plate 400 are all placed with the magazine 200, all the unprocessed battery pieces 190 only have one cutting surface 191, and the single cutting surface 191 of the unprocessed battery piece 190 faces the outside of the carrier plate 400, and the mapping relationship is that the magazine 200 in the upper left area ① is carried to the first row A, the magazine 200 in the upper right area ② is carried to the second row B, and the magazine 200 in the lower left area ③ is carried to the third row C, and each column of the carrier boat 300 is placed with 1.5 whole pieces.

[0077] As shown in FIG. 4, when the unprocessed battery piece 190 is a three-split battery piece and the single magazine position of the carrier boat 300 is three (the first row A to the third row C arranged from bottom to top), the upper left area ①, the upper right area ② and the lower left area ③ of the carrier plate 400 are all placed with the magazine 200, the unprocessed battery piece 190 in the upper left area and the lower left area only has one cutting surface 191, the unprocessed battery piece 190 in the upper right area has two cutting surfaces 191, and the single cutting surface 191 of the unprocessed battery piece 190 in the upper left area and the lower left area faces the outside of the carrier plate 400, and the double cutting surfaces 191 of the unprocessed battery piece 190 in the upper right area respectively face the outside and the inside of the carrier plate 400, and the mapping relationship is that the magazine 200 in the upper left area ① is carried to the first row A, the magazine 200 in the upper right area ② is carried to the second row B, and the magazine 200 in the lower left area ③ is carried to the third row C, and each column of the carrier boat 300 is placed with 1 whole piece.

[0078] As shown in FIG. 5, when the unprocessed battery piece 190 is a four-split battery piece and the single magazine position of the carrier boat 300 is four (the first row to the fourth row arranged from bottom to top), the four placement areas of the carrier plate 400 are all placed with the magazine 200, the unprocessed battery piece 190 in the upper left area and the lower right area only has one cutting surface 191, the unprocessed battery piece 190 in the upper right area and the lower left area has two cutting surfaces 191, and the single cutting surface 191 of the unprocessed battery piece 190 in the upper left area and the lower right area faces the outside of the carrier plate 400, and the double cutting surfaces 191 of the unprocessed battery piece 190 in the upper right area and the lower left area respectively face the outside and the inside of the carrier plate 400, and the mapping relationship is that the magazine 200 in the upper left area ① is carried to the first row A, the magazine 200 in the upper right area ② is carried to the second row B, the magazine 200 in the lower left area ③ is carried to the third row C, and the magazine 200 in the lower right area ④ is carried to the fourth row D, and each column of the carrier boat 300 is placed with 1 whole piece.

[0079] On the basis of the above cell piece handling method, the handling method further comprises:

[0080] After the crane 120 handles each box 200 on the carrier plate 400 to the corresponding position of the wafer boat 300, the wafer boat 300 filled with the boxes 200 becomes an unprocessed boat;

[0081] The unprocessed boat is sent into the reaction chamber 500, the processed boat is transferred to the docking boat position, the crane 120 handles the boxes 200 in the processed boat to the empty carrier plate 400 at the crane docking position, and the carrier plate 400 is transferred to the unloading position for unloading, and the empty carrier plate 400 is transferred to the loading position again;

[0082] After the reaction chamber 500 completes the process, the unprocessed boat becomes the processed boat, and the processed boat is placed in the temporary storage area 170 for cooling.

[0083] This handling method realizes continuous loading of the boxes 200, accurate boat filling, and sending of the unprocessed boat into the reaction chamber 500, while the processed boat after the process is cooled in time and the boxes 200 thereof are recycled to the carrier plate 400 for unloading, and the empty carrier plate 400 is recycled for use. This design not only realizes efficient utilization of the wafer boat 300 and the carrier plate 400, reduces invalid waiting and manual intervention, and realizes high productivity, high yield, and low cost operation in the entire process.

[0084] As an optimization, the cell piece handling method further comprises:

[0085] Before the unprocessed boat is sent into the reaction chamber 500, it is determined whether the reaction chamber 500 meets the boat pushing condition, which can be that the reaction chamber 500 is empty of boats, and a boat pushing mechanism 150 for sending or pushing the wafer boat 300 into or out of the reaction chamber 500 is in a standby state;

[0086] If yes, the unprocessed boat is sent into the reaction chamber 500;

[0087] If no, the unprocessed boat is placed in the variable docking boat position 800, and waits for the reaction chamber 500 to meet the boat pushing condition;

[0088] Among them, there is at least one variable docking boat position, and a transfer docking boat position 700 is further arranged between the variable docking boat position 800 and the temporary storage area 170, and the processed boat is placed in the temporary storage area 170 for cooling after sequentially flowing through the variable docking boat position 800 and the transfer docking boat position 700, and the cooled processed boat is placed in the docking boat position 600 for unloading of the boxes 200 after flowing through the transfer docking boat position 700.

[0089] This design can make the variable docking position 800 and the transfer docking position 700 flow and wait, ensuring that the production process will not be interrupted due to the temporary busy of the reaction chamber. After the process is completed, the processed wafer boat 300 is sent to the temporary storage area 170 for cooling to prevent thermal stress from affecting subsequent operations or causing damage to the battery sheet.

[0090] As shown in Figure 2 , Figure 6 and Figure 7 , the present application also proposes a purification platform 100 which performs the above-mentioned battery sheet handling method, and the purification platform 100 includes a conveying line 110, a docking sliding table 130, a crane 120 and other main components.

[0091] The conveying line 110 is used to transport the carrier plate 400, which can adopt a double-layer belt line structure, and each layer of belt line can be further divided into multiple sections to facilitate more precise position control and transportation scheduling of the carrier plate 400. One end of the conveying line 110 is connected to the ALD edge passivation loading machine to receive the carrier plate 400 loaded with unprocessed material boxes 200, and the other end is connected to the ALD edge passivation unloading machine to output the carrier plate 400 loaded with processed battery sheet material boxes 200. The conveying line 110 is provided with a loading position, a crane docking position 111 and an unloading position, which are respectively used for receiving the carrier plate 400, interacting with the crane 120 and unloading the finished product.

[0092] The docking sliding table 130 is used to transport the wafer boat 300, and the docking sliding table 130 is provided with a docking docking position 600 and a transfer docking position 700, that is, the docking sliding table 130 can move linearly between the docking docking position 600 and the transfer docking position 700. The docking docking position 600 of the docking sliding table 130 is used for direct docking of the wafer boat 300 and transfer of the material box 200 with the crane 120, and the transfer docking position 700 of the docking sliding table 130 serves as a temporary parking point for the wafer boat 300 during different processing stages or waiting.

[0093] The crane 120 transports the material box 200 between the carrier plate 400 at the crane docking position 111 and the wafer boat 300 at the docking docking position 600. When the conveying line 110 transports the carrier plate 400 loaded with unprocessed material boxes 200 to the crane docking position 111, the crane 120 grabs the material box 200 on the carrier plate 400 from this position and transports it to the wafer boat 300 on the docking docking position 600 of the docking sliding table 130. Conversely, when the crane 120 needs to take out the processed material box 200 from the wafer boat 300, it also performs the transportation operation between the carrier plate 400 at the crane docking position 111 and the wafer boat 300 at the docking docking position 600. The crane 120 is designed to move linearly in the horizontal plane and / or the vertical plane, which simplifies the structure, improves the positioning accuracy and transportation efficiency.

[0094] To complete a full process cycle of the wafer boat 300, the clean station 100 further comprises a boat pushing mechanism 150, a hoist arm 160, a temporary storage area 170, and a boat hoisting mechanism 180.

[0095] The boat pushing mechanism 150 is used to push the wafer boat 300 loaded with unprocessed cassettes 200 from the docking slide 130 into the reaction chamber 500, and to pull the processed wafer boat 300 out of the reaction chamber 500 after the process is completed.

[0096] The hoist arm 160 carries the wafer boat 300 between the boat pushing mechanism 150 and the docking slide 130 (or other slides), and after the boat pushing mechanism 150 pushes the processed boat out of the reaction chamber 500, the hoist arm 160 docks and transfers it to the corresponding boat receiving position on the designated slide (such as the docking slide 130 or the variable slide 140).

[0097] The clean station 100 is provided with a temporary storage area 170, the number of temporary storage positions of which can be determined according to the overall production capacity and the cooling requirements of the boat, and is specially used to place the processed hot boat taken out of the reaction chamber 500 and requiring cooling, to ensure that its temperature is reduced to a safe range before subsequent operation.

[0098] The boat hoisting mechanism 180 carries the wafer boat 300 between the temporary storage area 170 and the intermediate boat receiving position, and completes the circulation of the wafer boat 300 from cooling to reuse.

[0099] To further improve the production flexibility of the system and cope with peak capacity, the clean station 100 can also be optionally provided with at least one variable slide 140, which also has the carrying capacity of the wafer boat 300 and is provided with a variable boat receiving position 800 and an intermediate boat receiving position 700, i.e. the variable slide 140 can move linearly between the variable boat receiving position 800 and the intermediate boat receiving position 700. The hoist arm 160 can flexibly transfer the wafer boat 300 between the boat pushing mechanism 150, the docking slide 130, and the variable slide 140, for example, when the docking slide 130 of the main process is saturated or needs to wait, the hot boat or the cold boat can be temporarily stored in the variable slide 140. In particular, the cooled processed boat can also be allowed to be temporarily stored in the intermediate boat receiving position for short-term buffering or waiting before being finally sent back to the docking slide 130 for unloading. This design increases the scheduling flexibility of the clean station 100.

[0100] In the preferred embodiment of the present application, the layout feature of the purification platform 100 is that the conveying directions of the conveying line 110, the docking sliding table 130 and the variable sliding table 140 are parallel to each other, and the conveying line 110, the docking sliding table 130, the variable sliding table 140, the overhead crane 120, the boat pushing mechanism 150, the hoisting arm 160, the temporary storage area 170 and the boat hoisting mechanism 180 are all arranged in the purification platform 100, and the feeding machine, the discharging machine and the reaction chamber 500 are arranged outside the purification platform 100. This modular and linear layout greatly optimizes the floor area of the purification platform 100, simplifies the collaborative control logic between multiple mechanisms, and improves the overall operation efficiency and maintainability of the equipment.

[0101] As shown in Figure 8 , 9 In some embodiments, the overhead crane 120 comprises a three-axis motion mechanism 10, the output end of the three-axis motion mechanism 10 is connected with a base 20, the base 20 is provided with a clamping assembly, the clamping assembly is used for clamping or releasing the box 200, and the three-axis motion mechanism 10 can drive the base 20 and the clamping assembly 30 located on the base 20 to move to a specified position in three-axis directions; the base is provided with at least one first driving member 201, and the output end of each first driving member 201 is connected with a buffer member 202; wherein the first driving member 201 drives the buffer member 202 to move in the vertical direction, so as to abut or move away from the top of the box 200.

[0102] When it is needed to carry the box 200 loaded with unprocessed battery pieces into the wafer boat 300, or to carry the box 200 loaded with processed battery pieces in the wafer boat 300 to the wafer plate 400 for next unloading, the three-axis motion mechanism 10 can drive the clamping assembly 30 to move to multiple columns and multiple rows of boxes 200 in the second direction and the third direction, clamp the box 200 through the movement in the first direction, start the first driving member 201, drive the buffer member 202 to move to the top of the clamped box 200 until abutting, then drive the clamping assembly 30 and the clamped box 200 to a specified position, and then control the first driving member 201 to reset the buffer member 202 and control the clamping assembly 30 to release, so as to realize the carrying of multiple boxes 200. Wherein, the first direction is the Z-axis direction, the second direction is the Y-axis direction, and the third direction is the X-axis direction. Figure 8 Figure 8 Figure 8

[0103] This design clamps the corresponding box 200 through the clamping assembly 30, and then drives all the buffer members 202 to move to the top of the clamped box 200 until abutting, so that the box 200 is more stable during the carrying process, and the problem of shaking of the box 200 is avoided.

[0104] As​​​Figure 10 、 11 As shown in FIGS. 1-3, in some embodiments, the boat lifting mechanism 180 comprises: a lifting assembly 1, which can drive the frame assembly 2 to reciprocate in the vertical direction; at least one frame assembly 2, each of which can reciprocate up and down along the lifting assembly 1, each frame assembly 2 comprising a connecting end 21 and a free end 22, the connecting end 21 being the end driven by the lifting assembly 1 to drive the entire frame assembly 2 to reciprocate in the vertical direction, and the free end 22 being oppositely arranged from the connecting end 21; a gripper assembly 3, which is arranged one-to-one with the frame assembly 2, each frame assembly 2 being provided with a gripper assembly 3, and the gripper assembly 3 being movably connected with the frame assembly 2, the position and number of the gripper 31 of the gripper assembly 3 being adapted to the boat ear 301 of the slide boat 300; a linear reciprocating drive mechanism, which is used to movably connect one gripper assembly 3 with a corresponding frame assembly 2, the linear reciprocating drive mechanism 4 being capable of driving the gripper assembly 3 to reciprocate between the free end 22 and the connecting end 21, the movement direction of the gripper assembly 3 being perpendicular to the lifting direction, and being parallel to the length direction of the slide boat 300, Figure 8 wherein the Y direction in FIGS. 1-3 is the length direction of the slide boat 300, and the X direction is the width direction of the slide boat 300, when the gripper assembly 3 moves under the drive of the linear reciprocating drive mechanism 4, the movement direction is linear movement parallel to the Y direction.

[0105] When lifting the slide boat, the frame assembly 2 is lifted by the lifting assembly 1, so that the gripper 31 on the frame assembly 2 is located below the boat ear 301 of the slide boat 300, then the linear reciprocating drive mechanism 4 is used to drive the gripper 31 to move along the length direction of the slide boat 300, so that the gripper 31 is located below the corresponding boat ear 301, and then the lifting assembly 1 is lifted to lift the slide boat.

[0106] When the slide boat is released, the action of the boat lifting mechanism 180 is completely opposite to that of lifting the slide boat. First, the lifting assembly 1 is lowered, so that the gripper 31 is separated from the boat ear 301, then the linear reciprocating drive mechanism 4 is used to drive the gripper 31 to move along the length direction of the slide boat 300, so that the gripper 31 is no longer located directly below the boat ear 301, and then the lifting assembly 1 drives the frame assembly 2 and the gripper assembly 3 connected to the frame assembly 2 to the next working position or standby position.

[0107] The boat lifting mechanism 180 further comprises: at least one horizontal movement assembly 5, the connecting end of the frame assembly 2 being connected with the horizontal movement assembly 5 and being capable of being driven by the horizontal movement assembly 5 to reciprocate in the horizontal direction, the horizontal movement assembly 5 being connected with the lifting assembly 1 and being capable of being driven by the lifting assembly 1 to drive the frame assembly 2 to reciprocate in the vertical direction. Based on the horizontal movement assembly 5 and the lifting assembly 1, the frame assembly 2 can move to any position on the tracks of the two assemblies, so as to grasp the slide boat 300 at the corresponding position.

[0108] This design grips the slide boat 300 in the length direction of the slide boat 300, so the width of each group of frame assemblies 2 and gripper assemblies 3 only needs to be adapted to the width of the slide boat 300, and no extra operation space needs to be prepared in the width direction of the slide boat 300, the required installation volume is small, and the size or cost of the equipment will not be increased.

[0109] It should be understood that the purification table 100 is also provided with a control module, and the above mechanisms are all electrically connected with the control module, and the start and stop of each mechanism are controlled through the control module to realize the automatic operation of the purification table 100.

[0110] The passivation equipment provided by the application includes a reaction chamber and the above-mentioned purification table, and the following will illustrate the battery piece carrying process of the passivation equipment by some application examples of the application, in which application examples, the purification table 100 is provided with a docking sliding table 130 and two variable sliding tables 140.

[0111] For a special state, i.e. when the passivation process is just started, the slide boat 300 inside the purification table 100 is in an empty boat state (no material box), as shown in Figure 1 、 2 The control module controls the conveying line 110 to accept the carrier plate 400 (containing an unprocessed material box) transmitted from the feeding machine, and then transmit the carrier plate 400 to the crane docking position 111, and then the crane 120 carries the material box 200 to the slide boat 300 at the docking boat position 600 of the docking sliding table 130; after the slide boat 300 is filled with unprocessed material boxes, the hoist arm 160 transmits the unprocessed boat from the docking boat position 600 of the docking sliding table 130 to the boat pushing mechanism 150, and then the boat pushing mechanism 150 sends the unprocessed boat into the reaction chamber 500; at this time, the empty carrier plate 400 on the conveying line 110 is sent to the matching discharging machine, and after the discharging machine processes the carrier plate 400, the carrier plate 400 is finally transmitted to the feeding machine through the lower belt line. In particular, if the reaction chamber 500 is full of boats or the boat pushing mechanism 150 is in a working state, i.e. does not meet the boat pushing condition, the hoist arm 160 can transmit the unprocessed boat from the docking boat position 600 of the docking sliding table 130 to one of the variable boat positions 800 of the two variable sliding tables 140, and can temporarily park the unprocessed boat at the variable boat position 800. In particular, when the control module determines that all the slide boats 300 inside the purification table 100 are in the “full material box” state, the carrier plate 400 of the last material box is stopped at the crane docking position 111 for the discharging process, and the segmented belt line between the crane docking position 111 and the feeding machine can continue to send unprocessed material boxes according to the production requirements.

[0112] For a conventional state, i.e. when the passivation process has been started, as shown in Figure 1 、 2As shown, the reaction chamber 500 has completed the process. The control module controls the boat pushing mechanism 150 to transfer the processed boat to the boom 160. The boom 160 then transfers the processed boat at the variable boat receiving position 800 to one of the two variable slides 140. Subsequently, the variable slide 140 operates and transfers the processed boat to the intermediate boat receiving position 700. Then, the boat lifting mechanism 180 moves the processed boat to the intermediate boat receiving position 700 of the variable slide and moves it to the temporary storage position in the temporary storage area 170, which is in the "boat-free" position. After the processed boat is cooled in the temporary storage area 170, when the temperature detection module determines that the processed boat has cooled to the predetermined temperature, the boat lifting mechanism 180... The cooled finished process boat is preferentially transferred to the docking slide 130 at the intermediate docking boat position, and then transferred to the docking boat position 600 by the docking slide 130. In particular, if the docking slide 130 is in operation, and the temperature detection module determines that the finished process boat has cooled down to the predetermined temperature, the temporary storage area 170 needs to be vacated for the finished process boat to be cooled later. The boat lifting mechanism 180 can also temporarily place the cooled finished process boat on the intermediate docking boat position 700 of the two variable slides 140, and finally be transported to the docking boat position 600 by the crane 160 at the variable docking boat position 800 of the two variable slides 140. At this time, the overhead crane 120 will transfer the processed material boxes from the processed boat at docking position 600 to the empty plate 400 at docking position 111. After the plate 400 is filled with processed material boxes, it will be conveyed by the conveyor line 110 to the unloading machine for unloading. Then, a new plate 400 (with unprocessed material boxes) will be conveyed to docking position 111 again to exchange material boxes 200 with the processed boat at docking position 600. The empty plate 400 and the empty material boxes 200 will be transferred to the conveyor line 110 through the unloading machine and then to the loading machine for recycling. The overhead crane 120 will transfer the material boxes 200 on the plate 400 to the wafer carrier boat 300 according to the mapping relationship. This cycle will continue until the wafer carrier boat 300 at docking position 600 is filled. Then, the unprocessed boat will be transported into the reaction chamber 500.
