Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing, specifically a module receiving device. Background Technology

[0002] After sorting and testing the wafers (such as silicon wafers), the wafers are classified according to the test results. For example, the wafers are divided into first-class wafers and second-class wafers, and then the wafers are collected separately according to their type.

[0003] The first type of sheet collection process is as follows: Multiple first collection stations are set up on the conveying path of the main conveyor line used to transport the sheets. Each collection station has a material box on both sides. When the first type of sheet is transported to the first collection station and needs to be collected into the material box on both sides of the first collection station, the collection mechanism collects the first type of sheet at the first collection station into the material box located on both sides of the first collection station. After the material box is full of the first type of sheet, it is transported to the material box conveying mechanism, which then transports the box full of the first type of sheet to the next station.

[0004] In addition, a tailing box is arranged at the output end of the main conveyor line. Some of the material pieces on the main conveyor line are collected into the tailing box. After the tailing box is full, the full tailing box is moved away manually, and then the empty tailing box is replenished to the output end of the main conveyor line manually, which is inefficient. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a wafer receiving device, the detailed technical solution of which is as follows:

[0006] A sheet receiving device includes a main conveyor line, a sheet receiving mechanism, a handling mechanism, a box changing mechanism, a material box conveying mechanism, and a tail material box transfer mechanism, wherein:

[0007] The main conveyor line conveys sheet materials along a first direction. The sheet materials include first type sheet materials and second type sheet materials. At least one first receiving station is provided on the conveying path of the main conveyor line.

[0008] Each receiving station is equipped with a receiving mechanism, which is configured to receive the first type of sheet conveyed to the corresponding first receiving station into the material boxes located on both sides of the first receiving station;

[0009] The box-changing mechanism is located after the last first receiving station on the main conveyor line;

[0010] A conveying mechanism is set on each side of the main conveyor line. Each conveying mechanism is configured to transport the material box filled with the first type of material sheet on the corresponding side to the box changing mechanism, and to pick up the empty material box from the box changing mechanism and transport the empty material box to the corresponding side of the first material receiving station.

[0011] The box conveying mechanism is located after the box changing mechanism. The box changing mechanism is configured to convey boxes filled with first-type material sheets to the box conveying mechanism, and to receive empty boxes conveyed by the box conveying mechanism.

[0012] A recycling station for placing the tail material box is set at the discharge end of the main conveyor line. The tail material box is used to receive the material pieces output from the discharge end of the main conveyor line.

[0013] The tail material box transfer mechanism is located between the recycling station and the box changing mechanism. The tail material box transfer mechanism is configured to transfer the tail material box with full material pieces to the box changing mechanism, and to pick up the empty material box from the box changing mechanism and transport the empty material box to the recycling station. The box changing mechanism is also configured to transport the tail material box with full material pieces to the material box conveying mechanism.

[0014] The sheet-collecting device provided in this application includes a tail box transfer mechanism that transfers a full tail box to a box-changing mechanism. This box-changing mechanism not only transports full boxes of the first type of sheet to a box conveying mechanism, but also transports full tail boxes to a box conveying mechanism. The box conveying mechanism then uniformly transports both full boxes of the first type of sheet and full tail boxes towards the next stage, thus simplifying the sheet-collecting process and improving efficiency. Furthermore, after the full tail boxes at the recycling station are removed and emptied, the tail box transfer mechanism picks up the empty boxes from the box-changing mechanism and transports them to the recycling station, thereby achieving automatic box-changing for the tail boxes.

[0015] In some embodiments, the box conveying mechanism includes a first box conveying line and a second box conveying line arranged in layers in the vertical direction, wherein the first box conveying line is configured to receive a box filled with first type of material pieces or a tail box filled with material pieces conveyed by the box changing mechanism, and to convey the box filled with first type of material pieces or the tail box filled with material pieces away from the box changing mechanism, and the second box conveying line is configured to convey an empty box toward the box changing mechanism.

[0016] By configuring the box conveying mechanism as a first box conveying line and a second box conveying line, the box conveying mechanism can both receive boxes filled with first-type sheets or boxes filled with tail sheets from the box changing mechanism, and convey the boxes filled with first-type sheets or boxes filled with tail sheets away from the box changing mechanism backwards. It can also supply empty boxes to the box changing mechanism, thus enabling the handling mechanism and the tail sheet transfer mechanism to obtain empty boxes from the box changing mechanism. Furthermore, the first and second box conveying lines are arranged vertically in layers, reducing the space occupied by the box conveying mechanism and ultimately reducing the overall size of the sheet receiving device.

[0017] In some embodiments, the box-changing mechanism includes a transfer conveyor and a lifting mechanism, wherein: the transfer conveyor is located between the last first receiving station on the main conveyor line and the lifting mechanism; the conveying mechanism is configured to transport a box filled with first-type sheets to the transfer conveyor and to pick up an empty box from the transfer conveyor; the lifting mechanism includes a second lifting drive and a second conveying unit, wherein the second conveying unit is connected to a movable component of the second lifting drive, and the second lifting drive is configured to drive the second conveying unit to move up and down, thereby driving the second conveying unit, the transfer conveyor, the first box conveyor line, and the second box. The conveyor line or tail box transfer mechanism is connected, wherein: when the second conveyor unit is connected to the transfer conveyor mechanism, it receives the box filled with first type of material pieces from the transfer conveyor mechanism, and conveys the empty box to the transfer conveyor mechanism; when the second conveyor unit is connected to the first box conveyor line, it conveys the box filled with first type of material pieces to the first box conveyor line; when the second conveyor unit is connected to the second box conveyor line, it receives the empty box conveyed by the second box conveyor line; when the second conveyor unit is connected to the tail box transfer mechanism, it receives the tail box filled with material pieces from the tail box transfer mechanism, and conveys the empty box to the tail box transfer mechanism.

[0018] The intermediate conveyor mechanism can buffer the material boxes output from the main conveyor line, preventing the working cycle of the lifting mechanism from affecting the conveying cycle of the main conveyor line. The lifting mechanism can selectively connect with the first material box conveyor line, the second conveyor line, the tail material box transfer mechanism, and the intermediate conveyor mechanism, so that the first material box conveyor line, the second conveyor line, and the tail material box transfer mechanism can alternately carry out material box handover with the intermediate conveyor mechanism.

[0019] In some embodiments, the receiving device includes two cassette conveying mechanisms arranged side-by-side after the cassette changing mechanism; two lifting mechanisms are provided, with one cassette conveying mechanism corresponding to the rear of each lifting mechanism; and a transfer conveying mechanism is configured to alternately dock with the two lifting mechanisms.

[0020] By setting up two material box conveying mechanisms and two lifting mechanisms, the two material box conveying mechanisms can exchange materials with the corresponding lifting mechanisms respectively, and the transfer conveying mechanism can alternately exchange materials with the two lifting mechanisms, thereby improving the material box turnover efficiency.

[0021] In some embodiments, the transfer conveying mechanism includes a second translation drive and a first conveying unit, wherein: the first conveying unit is connected to a movable part of the second translation drive; the conveying mechanism is configured to transport a cassette filled with first type of sheet material to the first conveying unit and to pick up an empty cassette from the first conveying unit; the second translation drive is configured to drive the first conveying unit to translate along a conveying path perpendicular to the main conveyor line, such that the first conveying unit alternately docks with two lifting mechanisms; the first conveying unit conveys the cassette to the lifting mechanism along a conveying path parallel to the main conveyor line.

[0022] By setting the transfer conveyor mechanism as a first conveyor driven by the second translation drive unit, the transfer conveyor mechanism and the two lifting mechanisms are alternately connected, and the transfer conveyor mechanism can convey the material box parallel to the conveying path of the main conveyor line, ensuring that it can smoothly exchange material boxes with the lifting mechanism.

[0023] In some embodiments, the tail material box transfer mechanism includes a first conveying mechanism, a second conveying mechanism, a third conveying mechanism, a fourth conveying mechanism, a fifth conveying mechanism, and a first translation mechanism, wherein:

[0024] The first and second conveying mechanisms are arranged side by side at the rear of the main conveyor line, and the fourth and fifth conveying mechanisms are arranged side by side on both sides of the main conveyor line. The fourth conveying mechanism can connect with one of the lifting mechanisms, and the fifth conveying mechanism can connect with the other lifting mechanism. The third conveying mechanism is located between the first and second conveying mechanisms and the fourth and fifth conveying mechanisms.

[0025] The first conveying mechanism and the second conveying mechanism are configured to translate along a conveying path perpendicular to the main conveyor line, such that the first conveying mechanism switches between the first box changing position and the recycling station, and the second conveying mechanism switches between the second box changing position and the recycling station, wherein the recycling station is located between the first box changing position and the second box changing position; when the first conveying mechanism switches to the recycling station, the second conveying mechanism switches to the second box changing position, and when the second conveying mechanism switches to the recycling station, the first conveying mechanism switches to the first box changing position.

[0026] The first translation mechanism is fixedly connected to the third conveying mechanism. The first translation mechanism is configured to drive the third conveying mechanism to translate along a conveying path perpendicular to the main conveyor line, such that the first end of the third conveying mechanism is connected to the first conveying mechanism switched to the first box-changing position, and the second end of the third conveying mechanism is connected to the fourth conveying mechanism; or the first end of the third conveying mechanism is connected to the second conveying mechanism switched to the second box-changing position, and the second end of the third conveying mechanism is connected to the fifth conveying mechanism, wherein:

[0027] When the third conveying mechanism docks with the first conveying mechanism, it receives the tail material box with full material pieces output by the first conveying mechanism, or conveys the empty material box to the first conveying mechanism.

[0028] When the third conveyor connects with the second conveyor, it receives the tail material box with full material pieces output by the second conveyor, or conveys the empty material box to the second conveyor.

[0029] When the third conveyor connects with the fourth conveyor, it conveys the tail box filled with material pieces to the fourth conveyor, or receives the empty material box conveyed by the fourth conveyor; the fourth conveyor is used to input the tail box filled with material pieces to the corresponding lifting mechanism, or to receive the empty material box conveyed by the corresponding lifting mechanism.

[0030] When the third conveyor connects with the fifth conveyor, it conveys the tail box filled with material pieces to the fifth conveyor, or receives the empty material box conveyed by the fifth conveyor; the fifth conveyor is used to input the tail box filled with material pieces to the corresponding lifting mechanism, or to receive the empty material box conveyed by the corresponding lifting mechanism.

[0031] By configuring the tail material box transfer mechanism, the mechanism can automatically collect the material sheets output from the main conveyor line into the tail material box located at the recycling station, transport the full tail material box to the lifting mechanism, and automatically transport the empty box back to the recycling station after receiving it from the lifting mechanism, thereby realizing the automatic box changing operation of the tail material box.

[0032] In some embodiments, the first conveying mechanism and the second conveying mechanism are fixedly connected, and the tail box transfer mechanism further includes a second translation mechanism. The second translation mechanism is connected to at least one of the first conveying mechanism and the second conveying mechanism, and the second translation mechanism is configured to drive the first conveying mechanism and the second conveying mechanism to translate along a conveying path perpendicular to the main conveying line.

[0033] The second translation mechanism drives the first and second conveying mechanisms to translate perpendicularly to the conveying path of the main conveyor line, thereby enabling the first and second conveying mechanisms to alternately enter the recycling station, reducing equipment costs.

[0034] In some embodiments, the receiving device further includes a first lifting conveying mechanism disposed after the material box conveying mechanism. The first lifting conveying mechanism is configured to connect to the first material box conveying line or the second material box conveying line by lifting, wherein: when the first lifting conveying mechanism connects to the first material box conveying line, it receives the material box or the tail material box full of material boxes conveyed by the first material box conveying line; when the first lifting conveying mechanism connects to the second material box conveying line, it conveys the empty material box to the second material box conveying line.

[0035] By setting a first lifting conveyor mechanism after the material box conveying mechanism, the first material box conveying line and the second material box conveying line can be connected to the AGV trolley via the first lifting conveyor mechanism. In this way, the material boxes that are full of the first type of material pieces or the tail material boxes that are full of material pieces output from the first material box conveying line can smoothly enter the AGV trolley, and the empty material boxes output from the AGV trolley can smoothly enter the second material box conveying line.

[0036] In some embodiments, the receiving device further includes a sheet picking and conveying mechanism disposed above the discharge end of the main conveyor line and above the recycling station. The sheet picking and conveying mechanism is configured to pick up the sheet from the discharge end of the main conveyor line, and after conveying the sheet to above the recycling station, release the sheet into the tail box.

[0037] By setting up a sheet collection and conveying mechanism, it can be ensured that the sheets on the discharge end of the main conveyor line can be smoothly collected into the tail material box located at the recycling station.

[0038] In some embodiments, at least one second receiving station is provided on the conveying path of the main conveyor line, located downstream of the first receiving station. The receiving device further includes at least one receiving unit, and each second receiving station is provided with a corresponding receiving unit. The receiving unit includes a transfer conveying mechanism, an insert conveying mechanism, and a basket lifting receiving mechanism, wherein: the insert conveying mechanism is located on the side of the main conveyor line, the basket lifting receiving mechanism is configured to carry the basket, and the basket's hopper faces the output end of the insert conveying mechanism; the transfer conveying mechanism is configured to pick up a second type of sheet from the second receiving station and convey the second type of sheet to the insert conveying mechanism; the insert conveying mechanism is configured to insert the second type of sheet into the hopper of the basket on the basket lifting receiving mechanism.

[0039] This configuration enables the receiving device of this application to automatically receive the second type of sheet.

[0040] In some embodiments, the basket lifting and receiving mechanism includes a third lifting drive, a support frame, a third conveying part, and a pressing part, wherein: the support frame is connected to a movable part of the third lifting drive, the third lifting drive is configured to drive the support frame to lift, and an accommodating space for accommodating the basket is formed between the top and bottom of the support frame; the third conveying part is disposed at the bottom of the support frame, and the pressing part is configured to press the basket located in the accommodating space onto the third conveying part; the third conveying part is configured to convey the basket toward or away from the insert conveying mechanism, so that the output end of the insert conveying mechanism is inserted into or withdrawn from the basket's hopper.

[0041] By configuring the material basket lifting and receiving mechanism, the material basket lifting and receiving mechanism can clamp the material basket and drive the material basket to lift and lower to collect the material pieces inserted by the insert conveying mechanism in sequence. On the other hand, the material basket lifting and receiving mechanism can drive the material basket to move toward or away from the insert conveying mechanism, so that the output end of the insert conveying mechanism can automatically insert into the material basket's hopper or withdraw from the material basket's hopper.

[0042] In some embodiments, the receiving device further includes a third translation mechanism, which is fixedly connected to the insert conveying mechanism. The third translation mechanism is configured to drive the insert conveying mechanism to translate perpendicularly to the conveying path of the insert conveying mechanism, so that the output end of the insert conveying mechanism is aligned with the hopper of the material basket.

[0043] By setting a third translation mechanism, the position of the insert conveying mechanism is adjusted to ensure that the output end of the insert conveying mechanism can be aligned with the hopper of the material basket. In particular, when the material basket includes two hoppers, the third translation mechanism drives the insert conveying mechanism to translate perpendicularly to the conveying path of the insert conveying mechanism, so that the output end of the insert conveying mechanism can be aligned with the two hoppers of the material basket successively, so as to carry out insert operations on the two hoppers.

[0044] In some embodiments, the receiving device further includes an adsorption-rotation mechanism disposed on the conveying path of the insert conveying mechanism, the adsorption-rotation mechanism being configured to pick up and rotate the second type of sheet on the insert conveying mechanism.

[0045] By setting an adsorption and rotation mechanism on the conveying path of the insert conveyor, the orientation of the second type of material on the insert conveyor is adjusted, ensuring that the second type of material can be inserted into the hopper in a uniform orientation.

[0075] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0076] Regarding the explanation of "rear process", the "rear process" of a certain station or component mentioned in this application refers to: the main conveyor line conveys from front to back, and along the conveying direction of the main conveyor line, a certain station or component is located behind another station or component.

[0077] As described in the background section, a tailings box is arranged at the output end of the main conveyor line. Some of the material pieces on the main conveyor line are collected into the tailings box. After the tailings box is full, the full tailings box is manually removed, and then the empty tailings box is manually replenished to the output end of the main conveyor line, which is inefficient.

[0078] In view of this, this application provides a receiving device that can automatically remove the tail box filled with material sheets from the output end of the main conveyor line and automatically replenish the empty material box to the output end of the main conveyor line, thereby improving the receiving efficiency.

[0079] like Figure 1 and Figure 2 As shown, the receiving device in this application includes a main conveyor line 1, a receiving mechanism 6, a handling mechanism 2, a box changing mechanism 3, a box conveying mechanism 4, and a tail box transfer mechanism 5, wherein:

[0080] The main conveyor line 1 conveys sheet metal from front to back along a first direction (e.g., the X direction). The sheet metal includes first-type sheet metal and second-type sheet metal. At least one first receiving station A is provided along the conveying path of the main conveyor line 1. For example, Figure 2 The illustrated embodiment has a total of 7 first receiving stations A. Other embodiments may have other numbers of first receiving stations A depending on the specific circumstances.

[0081] Each first receiving station A is equipped with a receiving mechanism 6, which is configured to receive the first type of sheet conveyed to the corresponding first receiving station A into the material box 100 located on both sides of the first receiving station A.

[0082] The receiving mechanism 6 can be, for example, a suction cup assembly driven by a translation module or a robotic arm. The translation module or robotic arm drives the suction cup assembly to move, so that the suction cup assembly picks up the first type of sheet from the first receiving station A and releases the picked-up first type of sheet into the material boxes 100 on both sides.

[0083] The receiving mechanism 6 can also be an upper adsorption conveyor line, such as... Figure 11 As shown, the upper adsorption conveyor line includes a conveyor belt 61 and a Bernoulli adsorption component 62. The Bernoulli adsorption component 62 can generate adsorption force, causing the material sheet to be adsorbed onto the conveyor belt 61. That is, the upper adsorption conveyor line has both adsorption and conveying functions. The upper adsorption conveyor line is erected above the main conveyor line 1, and the conveying direction of the upper adsorption conveyor line is perpendicular to the main conveyor line 1. The upper adsorption conveyor line can adsorb the first material sheet at the first receiving station A and convey it to both sides to the release position and then release it into the corresponding material box 100.

[0084] To improve the take-up speed and independence of each first take-up station A, optionally, each take-up station A may be equipped with a separate take-up mechanism 6.

[0085] The box-changing mechanism 3 is located after the last first receiving station A on the main conveyor line 1. For example, Figure 2 In the embodiment shown, the last first receiving station A is the 7th receiving station A along the conveying direction of the main conveyor line 1.

[0086] A conveying mechanism 2 is provided on each side of the main conveyor line 1. Each conveying mechanism 2 is configured to transport the material box 100 filled with first-type material sheets on the corresponding side to the box changing mechanism 3, and to pick up empty material boxes from the box changing mechanism 3 and transport the empty material boxes to the corresponding side of the first receiving station A. In other words, the conveying mechanism 2 realizes the automatic box changing operation of the material boxes on the corresponding side, that is, to transport the material box 100 filled with first-type material sheets on the corresponding side to the box changing mechanism 3, and to replenish the empty material boxes picked up from the box changing mechanism 3 to the empty receiving station A on the corresponding side.

[0087] The material box conveying mechanism 4 is located after the box changing mechanism 3. The box changing mechanism 3 is configured to convey the material box filled with the first type of material to the material box conveying mechanism 4, and to receive the empty material box conveyed by the material box conveying mechanism 4.

[0088] A recycling station B is provided at the discharge end of the main conveyor line 1 for placing the tail material box, which is used to receive the material sheets output from the discharge end of the main conveyor line 1. It should be noted that the material sheets output from the discharge end of the main conveyor line 1 may be either type I material sheets or type II material sheets.

[0089] The tail material box transfer mechanism 5 is located between the recycling station B and the box changing mechanism 3. The tail material box transfer mechanism 5 is configured to transfer the tail material boxes filled with material sheets at the recycling station B to the box changing mechanism 3, and to pick up empty boxes from the box changing mechanism 3 and transport the empty boxes to the recycling station B. The box changing mechanism 3 is also configured to transport the tail material boxes filled with material sheets to the box conveying mechanism 4. In other words, the tail material box transfer mechanism 5 realizes the automatic box changing operation of the tail material boxes at the recycling station B; that is, it transfers the tail material boxes filled with material sheets at the recycling station B to the box changing mechanism 3, and replenishes the empty boxes picked up from the box changing mechanism 3 to the vacant recycling station B.

[0090] The sheet-collecting device provided in this application uses a tail-piece box transfer mechanism 5 to transfer a full tail-piece box to a box-changing mechanism 3. Thus, the box-changing mechanism 3 not only transports the boxes filled with the first type of sheet material, transported by the handling mechanism 2, to the box conveying mechanism 4, but also transports the full tail-piece boxes transferred by the tail-piece box transfer mechanism 5 to the box conveying mechanism 4. Finally, the box conveying mechanism 4 uniformly transports the boxes filled with the first type of sheet material and the full tail-piece boxes towards the next stage, thereby simplifying the sheet-collecting process and improving collection efficiency. Furthermore, when a full tail-piece box is removed from recycling station B and becomes empty, the tail-piece box transfer mechanism 5 picks up the empty box from the box-changing mechanism 3 and transports it to recycling station B, ultimately achieving automatic box-changing operation for the tail-piece boxes.

[0091] In some production embodiments, the first type of wafers are those identified as defective after inspection by the wafer inspection device. These wafers are categorized into several subcategories (or grades) based on specific inspection indicators. For example, silicon wafers are typically graded based on parameters such as thickness, microcracks, or contamination. Correspondingly, the main conveyor line 1 can have the same number of first receiving stations A, each corresponding to one of the subcategories, on its conveying path. Each first receiving station A is used to receive the first type of wafers from one subcategory. Alternatively, the number of first receiving stations A on the conveying path of conveyor line 1 can exceed the number of subcategories, allowing each subcategory's first type of wafers to be received at one or more first receiving stations A, thereby reducing the risk of failure to receive the first type of wafers in a timely manner. Alternatively, the first type of wafers may not undergo further classification. In this case, one or more first receiving stations A can be set up on the conveying path of the main conveyor line 1, and all first type wafers are received at one or more first receiving stations A.

[0092] In other production embodiments, the first type of sheet material can also be qualified sheets material determined after testing. Qualified sheets material can also be divided into several subcategories (or grades) according to specific testing indicators. Similarly, the main conveyor line 1 can be equipped with the same number or more than the number of subcategories of first receiving stations A.

[0093] like Figures 1 to 3 As shown. Optionally, the conveying mechanism 2 includes a first translation drive unit 21, a first lifting drive unit 22, and a pickup unit 23, wherein: the first lifting drive unit 22 is connected to a movable part of the first translation drive unit 21, and the pickup unit 23 is connected to a movable part of the first lifting drive unit 22. The first translation drive unit 21 is configured to drive the pickup unit 23 to translate parallel to the conveying path of the main conveyor line 1, and the first lifting drive unit 22 is configured to drive the pickup unit 23 to lift.

[0094] Driven by the first translation drive unit 21 and the first lifting drive unit 22, the picking unit 23 picks up a cassette 100 filled with first-type sheets from the corresponding side of the first receiving station A, and transports the picked-up cassette 100 filled with first-type sheets to the cassette changing mechanism 3. It also picks up an empty cassette from the cassette changing mechanism 3 and transports the picked-up empty cassette to the corresponding side of the first receiving station A.

[0095] Both the first translation drive unit 21 and the first lifting drive unit 22 can adopt various existing linear drive modules, such as a screw drive module composed of a motor, a lead screw, and a lead screw nut, or a synchronous belt drive module composed of a motor, a synchronous belt, and a slide rail. Figure 3 As shown, the pickup unit 23 includes a U-shaped mounting bracket with the U-shaped opening facing downwards. Two hooks are provided at the lower ends of the two side plates of the mounting bracket, meaning the pickup unit 23 has a total of 4 hooks. The 4 hooks are used to hook the 4 posts on the material box 100 one by one, so as to realize that the pickup unit 23 hooks the material box 100.

[0096] like Figure 5 As shown, optionally, the material box conveying mechanism 4 includes a first material box conveying line 41 and a second material box conveying line 42 arranged in layers in the vertical direction. The first material box conveying line 41 is configured to receive the material box filled with the first type of material pieces or the tail material box filled with material pieces conveyed by the box changing mechanism 3, and to convey the material box filled with the first type of material pieces or the tail material box filled with material pieces away from the box changing mechanism 3 and backward. The second material box conveying line 42 is configured to convey the empty material box toward the box changing mechanism 3.

[0097] By setting the material box conveying mechanism 4 as the first material box conveying line 41 and the second material box conveying line 42, the material box conveying mechanism 4 can both receive the material box full of the first type of material pieces or the tail material box full of material pieces output by the box changing mechanism 3, and convey the material box full of the first type of material pieces or the tail material box full of material pieces away from the box changing mechanism 3 and backward, and can also supply empty material boxes to the box changing mechanism 3, so that the handling mechanism 2 and the tail material box transfer mechanism 5 can obtain empty material boxes from the box changing mechanism 3.

[0098] The first material box conveyor line 41 and the second material box conveyor line 42 are arranged in layers in the vertical direction, which reduces the space occupied by the material box conveying mechanism 4 and ultimately reduces the overall size of the receiving device. The first material box conveyor line 41 can be located above or below the second material box conveyor line 42.

[0099] like Figures 1 to 2 As shown, optionally, the box-changing mechanism 3 includes a transfer conveying mechanism 31 and a lifting mechanism 32. Specifically:

[0100] The transfer conveyor 31 is located between the last first receiving station A on the main conveyor line 1 and the lifting mechanism 32. The handling mechanism 2 is configured to transport boxes filled with first-type sheets to the transfer conveyor 31 and to pick up empty boxes from the transfer conveyor 31, such as... Figure 7 As shown, the lifting mechanism 32 includes a second lifting drive unit 321 and a second conveying unit 322. The second conveying unit 322 is connected to a movable component of the second lifting drive unit 321. The second lifting drive unit 321 is configured to drive the second conveying unit 322 to lift and lower, thereby enabling the second conveying unit 322 to dock with the transfer conveying mechanism 31, the first material box conveying line 41, the second material box conveying line 42, or the tail material box transfer mechanism 5. Specifically: when the second conveying unit 322 docks with the transfer conveying mechanism 31, the lifting mechanism 32 receives a material box filled with the first type of material pieces from the transfer conveying mechanism 31, or conveys an empty material box to the transfer conveying mechanism 31. When the second conveying unit 322 docks with the first material box conveying line 41, the lifting mechanism 32 conveys a material box filled with the first type of material pieces to the first material box conveying line 41. When the second conveying unit 322 docks with the second material box conveying line 42, the lifting mechanism 32 receives an empty material box conveyed by the second material box conveying line 42. When the second conveying unit 322 connects with the tail material box transfer mechanism 5, the lifting mechanism 32 receives the tail material box with full material pieces conveyed by the tail material box transfer mechanism 5, or conveys the empty material box to the tail material box transfer mechanism 5.

[0101] The intermediate conveyor mechanism 31 can buffer the material boxes output from the main conveyor line 1, preventing the working cycle of the lifting mechanism 32 from affecting the conveying cycle of the main conveyor line 1. The lifting mechanism 32 can selectively connect with the first material box conveyor line 41, the second material box conveyor line 42, the tail material box transfer mechanism 5, and the intermediate conveyor mechanism 31, so that the first material box conveyor line 41, the second material box conveyor line 42, and the tail material box transfer mechanism 5 can all achieve material box handover with the intermediate conveyor mechanism 31.

[0102] The second lifting drive unit 321 can adopt various existing linear drive modules, such as a screw drive module consisting of a motor, lead screw, nut, and lifting plate. That is, the motor drives the lifting plate to rise and fall via the lead screw and nut, and the second conveying unit 322 is mounted on the lifting plate. The second conveying unit 322 can, for example, be a motor-driven conveyor belt capable of bidirectional transport. For example, when the second conveying unit 322 connects to the first material box conveyor line 41, the conveyor belt of the second conveying unit 322 transports the material box filled with the first type of material sheet towards the first material box conveyor line 41, thereby conveying the material box onto the first material box conveyor line 41 backwards. When the second conveying unit 322 connects to the second material box conveyor line 42, the conveyor belt of the second conveying unit 322 transports the material box away from the second material box conveyor line 42, thereby receiving the empty material boxes output forward by the second material box conveyor line 42.

[0103] like Figures 1 to 2 As shown, optionally, the receiving device in this embodiment includes two box conveying mechanisms 4 arranged side-by-side after the box changing mechanism 3. The lifting mechanisms 32 of the box changing mechanism 3 are also arranged side-by-side, with one box conveying mechanism 4 corresponding to the rear of each lifting mechanism 32 along the conveying direction of the main conveyor line 1. The transfer conveying mechanism 31 is configured to alternately dock with the two lifting mechanisms 32.

[0104] By setting up two material box conveying mechanisms 4 and two lifting mechanisms 32, the two material box conveying mechanisms 4 can exchange material boxes with the corresponding lifting mechanisms 32 respectively, and the transfer conveying mechanism 31 can exchange material boxes with the two lifting mechanisms 32 alternately, thereby improving the material box circulation efficiency.

[0105] like Figure 4 and Figure 5 As shown, optionally, the transfer conveying mechanism 31 includes a second translation drive unit 311 and a first conveying unit 312, wherein the first conveying unit 312 is connected to a movable part of the second translation drive unit 311. The handling mechanism 2 is configured to transport a cassette filled with first-type sheet material to the first conveying unit 312 and to pick up an empty cassette from the first conveying unit 312. The second translation drive unit 311 is configured to drive the first conveying unit 312 to translate along a conveying path perpendicular to the main conveyor line 1, so that the first conveying unit 312 alternately engages with two lifting mechanisms 32. The first conveying unit 312 conveys the cassette to the lifting mechanism 32 along a conveying path parallel to the main conveyor line 1.

[0106] By setting the transfer conveyor 31 as the first conveyor 312 driven by the second translation drive 311, the transfer conveyor 31 and the two lifting mechanisms 32 are alternately connected, and the transfer conveyor 31 can convey the material box parallel to the conveying path of the main conveyor line 1, ensuring that it can smoothly exchange material boxes with the lifting mechanism 32.

[0107] The second translation drive unit 311 can adopt various existing linear drive modules, such as a screw drive module consisting of a motor, a lead screw, a nut, and a translation plate, or a synchronous belt drive module consisting of a motor, a synchronous belt, and a slide rail. The first conveying unit 312 is mounted on the translation plate. The first conveying unit 312 can be, for example, a conveyor belt driven by a motor that can perform bidirectional conveying.

[0108] like Figures 6 to 7 As shown, optionally, the tail material box transfer mechanism 5 includes a first conveying mechanism 51, a second conveying mechanism 52, a third conveying mechanism 53, a fourth conveying mechanism 54, a fifth conveying mechanism 55, and a first translation mechanism 56, wherein:

[0109] The first conveying mechanism 51 and the second conveying mechanism 52 are arranged side by side at the rear of the main conveyor line 1 (i.e., behind the output end of the main conveyor line 1). The fourth conveying mechanism 54 and the fifth conveying mechanism 55 are arranged side by side on both sides of the main conveyor line 1. The fourth conveying mechanism 54 can dock with one of the lifting mechanisms 32, and the fifth conveying mechanism 55 can dock with the other lifting mechanism 32. The third conveying mechanism 53 is located between the first conveying mechanism 51, the second conveying mechanism 52, the fourth conveying mechanism 54, and the fifth conveying mechanism 55.

[0110] The first conveying mechanism 51 and the second conveying mechanism 52 are configured to translate along a conveying path perpendicular to the main conveying line 1 (e.g., translation along the Y direction) so that the first conveying mechanism 51 switches between the first box changing position C and the recycling station B, and the second conveying mechanism 52 switches between the second box changing position D and the recycling station B. The recycling station B is located between the first box changing position C and the second box changing position D. When the first conveying mechanism 51 switches to the recycling station B, the second conveying mechanism 52 switches to the second box changing position D. When the second conveying mechanism 52 switches to the recycling station B, the first conveying mechanism 51 switches to the first box changing position C.

[0111] The first translation mechanism 56 is fixedly connected to the third conveying mechanism 53. The first translation mechanism 56 is configured to drive the third conveying mechanism 53 to translate along a conveying path perpendicular to the main conveyor line 1 (e.g., along the Y direction), so that the first end of the third conveying mechanism 53 is connected to the first conveying mechanism 51 switched to the first box-changing position C, and the second end of the third conveying mechanism 53 is connected to the fourth conveying mechanism 54. Alternatively, the first end of the third conveying mechanism 53 is connected to the second conveying mechanism 52 switched to the second box-changing position D, and the second end of the third conveying mechanism 53 is connected to the fifth conveying mechanism 55, wherein:

[0112] When the third conveying mechanism 53 connects with the first conveying mechanism 51, it receives the tail material box with full material pieces output by the first conveying mechanism 51, or conveys the empty material box to the first conveying mechanism 51.

[0113] When the third conveying mechanism 53 docks with the second conveying mechanism 52, it receives the tail material box with full material pieces output by the second conveying mechanism 52, or conveys the empty material box to the second conveying mechanism 52.

[0114] When the third conveying mechanism 53 connects with the fourth conveying mechanism 54, it conveys the tail material box filled with material pieces to the fourth conveying mechanism 54, or receives the empty material box conveyed by the fourth conveying mechanism 54.

[0115] The fourth conveying mechanism 54 is used to input the tail material box filled with material pieces to the corresponding lifting mechanism 32, or to receive the empty material box conveyed by the corresponding lifting mechanism 32.

[0116] When the third conveying mechanism 53 connects with the fifth conveying mechanism 55, it conveys the tail material box filled with material pieces to the fifth conveying mechanism 55, or receives the empty material box conveyed by the fifth conveying mechanism 55.

[0117] The fifth conveying mechanism 55 is used to input the tail material box filled with material pieces to the corresponding lifting mechanism 32, or to receive the empty material box conveyed by the corresponding lifting mechanism 32.

[0118] The optional working process of the tail material box transfer mechanism 5 is as follows:

[0119] In the initial state, both the first conveying mechanism 51 and the second conveying mechanism 52 carry empty tailing boxes.

[0120] First, control the first conveyor mechanism 51 to translate and switch to the recycling station B, and control the second conveyor mechanism 52 to translate and switch to the second box-changing position D. The tail material box on the first conveyor mechanism 51 collects the material pieces.

[0121] When the tail material box on the first conveyor mechanism 51 is full, the first conveyor mechanism 51 is controlled to shift to the first box-changing position C, and the second conveyor mechanism 52 is controlled to shift to the recycling station B. The tail material box on the second conveyor mechanism 52 collects the material pieces. At the same time, the third conveyor mechanism 53 docks with the first conveyor mechanism 51 to receive the tail material box with full material pieces output by the first conveyor mechanism 51. Simultaneously, the third conveyor mechanism 53 docks with the fourth conveyor mechanism 54 to transport the tail material box with full material pieces to the fourth conveyor mechanism 54. The fourth conveyor mechanism 54 transports the tail material box with full material pieces to the second conveyor section 322 of the corresponding lifting mechanism 32. The second conveyor section 322 rises to dock with the first material box conveyor line 41. The second conveyor section 322 transfers the tail material box with full material pieces to the first material box conveyor line 41, which then transports the tail material box with full material pieces backward. Subsequently, the second conveying section 322 rises or falls to dock with the second material box conveying line 42. The second conveying section 322 receives the empty material box transmitted from the second material box conveying line 42. The second conveying section 322 then falls to dock with the fourth conveying mechanism 54. The empty material box on the second conveying section 322 is then transported to the first conveying mechanism 51 via the fourth conveying mechanism 54 and the third conveying mechanism 53.

[0122] When the tail material box on the second conveyor mechanism 52 is full of material pieces, the second conveyor mechanism 52 is again controlled to move and switch to the second box-changing position D, and the first conveyor mechanism 51 is controlled to move and switch to the recycling station B. The tail material box (i.e., the empty box) on the first conveyor mechanism 51 begins to collect material pieces. At the same time, the third conveyor mechanism 53 docks with the second conveyor mechanism 52 to receive the tail material box with full material pieces output by the second conveyor mechanism 52. Simultaneously, the third conveyor mechanism 53 docks with the fifth conveyor mechanism 55 to transport the tail material box with full material pieces to the fifth conveyor mechanism 55. The fifth conveyor mechanism 55 transports the tail material box with full material pieces to the second conveyor section 322 of the corresponding lifting mechanism 32. The second conveyor section 322 rises to dock with the first material box conveyor line 41. The second conveyor section 322 transfers the tail material box with full material pieces to the first material box conveyor line 41, which then transports the tail material box with full material pieces backward. Subsequently, the second conveying section 322 rises or falls to dock with the second material box conveying line 42. The second conveying section 322 receives the empty material box transmitted from the second material box conveying line 42. The second conveying section 322 then falls to dock with the fifth conveying mechanism 55. The empty material box on the second conveying section 322 is then transported to the second conveying mechanism 52 in sequence through the fifth conveying mechanism 55 and the third conveying mechanism 53.

[0123] Repeat the above film acquisition process.

[0124] As can be seen, by setting the tail material box transfer mechanism 5, the tail material box transfer mechanism 5 can automatically collect the material pieces output from the main conveyor line 1 into the tail material box located at the recycling station B, and transport the tail material box full of material pieces to the lifting mechanism 32, as well as receive the empty material box from the lifting mechanism 32 and automatically transport the empty material box back to the recycling station B, thereby realizing the automatic box changing operation of the tail material box.

[0125] The first translation mechanism 56 can adopt various existing linear drive modules, such as a screw drive module consisting of a motor, a lead screw, and a lead screw nut, or a synchronous belt drive module consisting of a motor, a synchronous belt, and a slide rail.

[0126] Optionally, the first conveying mechanism 51 and the second conveying mechanism 52 are fixedly connected. The tail box transfer mechanism 5 also includes a second translation mechanism 57, which is connected to at least one of the first conveying mechanism 51 and the second conveying mechanism 52. The second translation mechanism 57 is configured to drive the first conveying mechanism 51 and the second conveying mechanism 52 to translate along a conveying path perpendicular to the main conveying line 1.

[0127] The second translation mechanism 57 drives the first conveying mechanism 51 and the second conveying mechanism 52 to translate perpendicularly to the conveying path of the main conveying line 1, so that the first conveying mechanism 51 and the second conveying mechanism 52 can alternately enter the recycling station B, reducing equipment costs.

[0128] Of course, the first conveying mechanism 51 and the second conveying mechanism 52 can also be set separately and driven by their respective corresponding translation drive mechanisms. When the first conveying mechanism 51 switches to the recycling station B under the drive of its corresponding translation drive mechanism, the second conveying mechanism 52 switches to the second box-changing position D under the drive of its corresponding translation drive mechanism. When the second conveying mechanism 52 switches to the recycling station B under the drive of its corresponding translation drive mechanism, the first conveying mechanism 51 switches to the first box-changing position C under the drive of its corresponding translation drive mechanism. This setting enables independent translation of the first conveying mechanism 51 and the second conveying mechanism 52. If one of the first conveying mechanism 51 or the second conveying mechanism 52 malfunctions and cannot perform normal film receiving and conveying, the other can still perform normal film receiving and conveying. The second translation mechanism 57 and the translation drive mechanism can also adopt various existing linear drive modules, such as a screw drive module composed of a motor, a lead screw, and a lead screw nut, or a synchronous belt drive module composed of a motor, a synchronous belt, and a slide rail.

[0129] like Figure 1 , Figure 2 and Figure 5As shown, optionally, the receiving device in this embodiment further includes a first lifting conveyor mechanism 7 disposed after the material box conveying mechanism 4. The first lifting conveyor mechanism 7 is configured to connect to the first material box conveying line 41 or the second material box conveying line 42 by lifting. When the first lifting conveyor mechanism 7 connects to the first material box conveying line 41, it receives the material box filled with first-type material sheets or the tail material box filled with material sheets conveyed by the first material box conveying line 41. When the first lifting conveyor mechanism 7 connects to the second material box conveying line 42, it conveys the empty material box to the second material box conveying line 42.

[0130] The first lifting conveyor 7 can be used to dock with the AGV trolley. By setting the first lifting conveyor 7 after the material box conveyor 4, the docking of the first material box conveyor line 41, the second material box conveyor line 42 and the AGV trolley is realized. This allows the material boxes that are full of the first type of material pieces or the tail material boxes that are full of material pieces output from the first material box conveyor line 41 to be smoothly transported and transferred to the AGV trolley via the first lifting conveyor 7. The empty material boxes output from the AGV trolley can be smoothly transported and transferred to the second material box conveyor line 42 via the first lifting conveyor 7.

[0131] Optionally, the first lifting and conveying mechanism 7 includes a lifting module and a conveyor belt mounted on the moving parts of the lifting module. The lifting module can be formed by a motor and a screw and nut mechanism. The lifting module is used to drive the conveyor belt to lift and lower, so that the conveyor belt can dock with the first material box conveyor line 41, the second material box conveyor line 42, or the AGV trolley. When the conveyor belt docks with the first material box conveyor line 41, it can receive the material box filled with the first type of material pieces or the tail material box filled with material pieces conveyed by the first material box conveyor line 41. When the conveyor belt docks with the second material box conveyor line 42, it can convey the empty material box received from the AGV trolley to the second material box conveyor line 42. When the conveyor belt docks with the AGV trolley, it can convey the material box filled with the first type of material pieces or the tail material box filled with material pieces received from the first material box conveyor line 41 to the AGV trolley, or receive the empty material box output by the AGV trolley.

[0132] like Figures 5 to 6 As shown, optionally, the receiving device in this embodiment of the application further includes a receiving conveying mechanism 8 disposed above the discharge end of the main conveyor line 1 and above the recycling station B. The receiving conveying mechanism 8 is configured to pick up the sheet from the discharge end of the main conveyor line 1, and after conveying the sheet to the top of the recycling station B, release the sheet into the tail box.

[0133] By setting up the sheet collection and conveying mechanism 8, it can be ensured that the sheet material on the discharge end of the main conveyor line 1 can be smoothly collected into the tail material box located at the recycling station B.

[0134] Optionally, the sheet collection and conveying mechanism 8 is also an upper adsorption conveyor line. Specifically, the sheet collection and conveying mechanism 8 includes a mounting bracket, a Bernoulli adsorption assembly, and at least two conveyor belts. The at least two conveyor belts are arranged parallel to each other on the mounting bracket, and their conveying direction is the same as that of the main conveyor line 1. The lower conveying surfaces of each conveyor belt are located on the same plane. The Bernoulli adsorption assembly is mounted on the mounting bracket and located between two adjacent conveyor belts. The adsorption surface of the Bernoulli adsorption assembly is higher than the conveying surface of the conveyor belt. The Bernoulli adsorption assembly is used to adsorb the sheet located at the discharge end of the main conveyor line 1, so that the sheet is attached to the lower conveying surface of the conveyor belt. After the conveyor belt conveys the sheet above the recycling station B, the Bernoulli adsorption assembly stops adsorption, so that the sheet falls into the tail material box.

[0135] like Figure 2 As shown, optionally, at least one (two in the figure) second receiving station E is also provided on the conveying path of the main conveyor line 1, located downstream of the first receiving station A. The receiving device in this embodiment further includes at least one receiving unit, with a corresponding receiving unit provided at each second receiving station E. The receiving unit includes a transfer conveying mechanism 9, an insert conveying mechanism 10, and a basket lifting receiving mechanism 110, wherein: the insert conveying mechanism 10 is located on the side of the main conveyor line 1, and the basket lifting receiving mechanism 110 is configured to carry the basket 200, with the hopper of the basket 200 facing the output end of the insert conveying mechanism 10. The transfer conveying mechanism 9 is configured to pick up the second type of sheet from the second receiving station E and convey the second type of sheet to the insert conveying mechanism 10. The insert conveying mechanism 10 is configured to insert the second type of sheet into the hopper of the basket 200 on the basket lifting receiving mechanism 110.

[0136] This configuration enables the receiving device in this embodiment to automatically receive second-type sheets in addition to the first-type sheets. For example, in some production embodiments, the first-type sheets are defective sheets, and the second-type sheets are qualified sheets. In other production embodiments, the first-type sheets are qualified sheets, and the second-type sheets are defective sheets.

[0137] like Figure 2 and Figure 8 As shown, optionally, receiving units are provided on both sides of the second receiving station E. In this way, the two receiving units can take turns receiving the second type of material at the second receiving station E, thereby reducing the risk that the second type of material at the second receiving station E may not be received in time.

[0138] The second type of sheet material can be divided into several subcategories (or grades) based on specific testing indicators. Correspondingly, the same number of second receiving stations E, each corresponding to one of the subcategories, can be set up on the conveying path of the main conveyor line 1. Each second receiving station E is used to collect the second type of sheet material from one subcategory. Of course, the number of second receiving stations E set up on the conveying path of conveyor line 1 can also be more than the number of subcategories. The second type of sheet material from each subcategory can be collected at one or more second receiving stations E, reducing the possibility that the second type of sheet material from each subcategory will not be collected in time. Alternatively, the second type of sheet material may not be further classified. In this case, one or more second receiving stations E can be set up on the conveying path of the main conveyor line 1, and all the second type of sheet material will be collected at one or more second receiving stations E.

[0139] Optionally, the transfer and conveying mechanism 9 can also be an upper adsorption conveyor line. After the upper adsorption conveyor line picks up the second type of material at the second receiving station E and conveys it above the insert conveyor mechanism 10, the upper adsorption conveyor line stops adsorption, so that the second type of material falls into the insert conveyor mechanism 10.

[0140] like Figures 9 to 10 As shown, optionally, the material basket lifting and receiving mechanism 110 includes a third lifting drive unit 111, a support frame 112, a third conveying unit 113 and a pressing unit 114, wherein: the support frame 112 is connected to the movable part of the third lifting drive unit 111, the third lifting drive unit 111 is configured to drive the support frame 112 to lift, and a receiving space for accommodating the material basket is formed between the top and bottom of the support frame 112.

[0141] The third conveying section 113 is provided at the bottom of the support frame 112, and the clamping section 114 is configured to clamp the material basket located in the accommodating space onto the third conveying section 113. The third conveying section 113 is configured to convey the material basket toward or away from the insert conveying mechanism 10, so that the output end of the insert conveying mechanism 10 is inserted into or withdrawn from the material basket's hopper.

[0142] By configuring the material basket lifting and receiving mechanism 110, the material basket lifting and receiving mechanism 110 can, on the one hand, clamp the material basket and drive the material basket to lift and lower to collect the material pieces inserted by the insert conveying mechanism 10 in sequence, and on the other hand, drive the material basket to move toward or away from the insert conveying mechanism 10, so that the output end of the insert conveying mechanism 10 can be automatically inserted into the material basket's hopper or withdrawn from the material basket's hopper.

[0143] The optional inserting process of the insert conveying mechanism 10 and the material basket lifting and receiving mechanism 110 is as follows:

[0144] In the initial state, the output end of the insert conveying mechanism 10 is located outside the accommodating space of the material basket lifting and receiving mechanism 110, and the support frame 112 is located at a low position.

[0145] The material basket enters the receiving space under the conveying of the third conveying section 113, and the pressing section 114 presses the material basket onto the third conveying section 113.

[0146] Subsequently, the third conveying unit 113 conveys the material basket toward the insert conveying mechanism 10, thereby causing the output end of the insert conveying mechanism 10 to be inserted into the bottom of the material basket's hopper.

[0147] Subsequently, the third lifting drive unit 111 drives the support frame 112 to rise to a preset height each time, so that each empty slot in the hopper is flush with the conveying surface of the output end of the insert conveying mechanism 10 in turn, and the insert conveying mechanism 10 inserts the second type of material into each slot in turn.

[0148] After inserting the inserts into all the slots in the hopper, the third conveying unit 113 moves the hopper away from the insert conveying mechanism 10, thereby causing the output end of the insert conveying mechanism 10 to be withdrawn from the hopper.

[0149] Once the clamping part 114 releases the clamping on the material basket, the third conveying part 113 can output the material basket from the receiving space.

[0150] The third lifting drive unit 111 can be any existing linear drive module capable of driving the support frame 112 to rise and fall. For example, the third lifting drive unit 111 can be a vertical linear module. The third conveying unit 113 can be two conveyor belts arranged side-by-side on the support frame 112. The pressing unit 114 can, for example, include a cylinder and a pressing plate, with the cylinder driving the pressing plate to descend so that the pressing plate presses against the upper end of the material basket.

[0151] To monitor whether the sheets in the hopper are collected, a through-beam sensor can be installed on the third lifting drive unit 111 (e.g., on the housing of the linear module, in the non-lifting part). The through-beam sensor is roughly flush with the conveying surface of the output end of the insert conveying mechanism 10 and is arranged at the entrance of the hopper. The through-beam sensor is used to detect whether the sheets are inserted into the slots. If the sheets in the hopper are not inserted into the slots, they can be aligned manually or by other auxiliary mechanisms.

[0152] like Figure 9 As shown, optionally, the receiving device in this embodiment of the application further includes a third translation mechanism 120, which is fixedly connected to the insert conveying mechanism 10. The third translation mechanism 120 is configured to drive the insert conveying mechanism 10 to translate perpendicularly to the conveying path of the insert conveying mechanism 10, so that the output end of the insert conveying mechanism 10 is aligned with the hopper of the material basket.

[0153] By setting a third translation mechanism 120, the position of the insert conveying mechanism 10 is adjusted to ensure that the output end of the insert conveying mechanism 10 is aligned with the hopper of the material basket, thereby enabling the insert conveying mechanism 10 to smoothly insert the material into the hopper. In particular, when the material basket includes two hoppers, each hopper is used to collect small-sized material (such as half a battery cell), the third translation mechanism 120 drives the insert conveying mechanism 10 to translate perpendicularly to the conveying path of the insert conveying mechanism 10, so that the output end of the insert conveying mechanism 10 can be aligned with the two hoppers of the material basket in turn to carry out the insert operation on the two hoppers, and finally make both hoppers full of material.

[0154] Specifically, when the material basket includes two hoppers, and one hopper is full of material pieces, the third conveying unit 113 drives the material basket to move away from the insert conveying mechanism 10, so that the output end of the insert conveying mechanism 10 is withdrawn from the hopper of the material basket. Then, the third translation mechanism 120 drives the insert conveying mechanism 10 to move laterally, so that the output end of the insert conveying mechanism 10 is aligned with the other hopper of the material basket. After that, the third conveying unit 113 drives the material basket to move closer to the insert conveying mechanism 10, so that the output end of the insert conveying mechanism 10 is inserted into the other hopper of the material basket. The insert conveying mechanism 10 continues to insert material pieces into the other hopper, thus realizing the switching of material collection between the two hoppers.

[0155] The third translation mechanism 120 can be any existing linear drive module capable of driving the insert conveying mechanism 10 to translate perpendicularly to the conveying path of the insert conveying mechanism 10.

[0156] like Figure 9 As shown, optionally, the receiving device in this embodiment of the application further includes an adsorption and rotation mechanism 130 disposed on the conveying path of the insert conveying mechanism 10. The adsorption and rotation mechanism 130 is configured to pick up the second type of material sheet on the insert conveying mechanism 10 and rotate it, thereby realizing the orientation adjustment of the second type of material sheet on the insert conveying mechanism 10, ensuring that the second type of material sheet can be inserted into the hopper in a uniform orientation.

[0157] Optionally, the adsorption rotation mechanism 130 includes a rotation drive 131 and a suction cup 132, wherein the suction cup 132 is connected to the drive end of the rotation drive 131. The suction cup 132 is disposed adjacent to and above the insert conveying mechanism 10. The suction cup 132 is used to pick up or release inserts, and the rotation drive 131 is used to drive the suction cup 132 and the inserts to rotate, thereby adjusting the orientation of the inserts. The rotation drive 131 may be a motor.

[0158] like Figure 1 , Figure 2 and Figure 5As shown, optionally, a basket conveying mechanism 140 is provided after the basket lifting and receiving mechanism 110. The basket conveying mechanism includes a first basket conveying line 141 and a second basket conveying line 142 arranged in layers in the vertical direction. The third lifting drive unit 111 is also configured to drive the support frame 112 to lift, so that the third conveying unit 113 docks with the first basket conveying line 141 or the second basket conveying line 142.

[0159] When the third conveying unit 113 connects with the first basket conveyor line 141, the third conveying unit 113 conveys a basket filled with second-type material pieces onto the first basket conveyor line 141, which then conveys the basket filled with second-type material pieces backward.
