Description

Technical Field

[0001] This application relates to the field of photovoltaic cell module production equipment, and more specifically, to a basket transfer and loading device. Background Art

[0002] During the production of photovoltaic cell modules, it is necessary to load silicon wafers from a basket onto a silicon wafer conveyor line one by one. The existing silicon wafer loading device only includes a basket transfer mechanism, which is used to move the basket containing silicon wafers to the input end of the silicon wafer conveyor line, so that the silicon wafers in the basket fall onto the silicon wafer conveyor line one by one.

[0003] After the silicon wafers in the basket are emptied, the transfer mechanism moves the emptied basket to the basket replacement station for basket replacement. In the existing silicon wafer loading device, when the transfer mechanism performs the basket replacement operation, the feeding interval time of the silicon wafer conveyor line is relatively long, resulting in a long feeding waiting time and reducing the feeding efficiency. Utility Model Content

[0004] In order to solve the above technical problems, this application provides a basket transfer and loading device, which adopts the following technical solutions:

[0005] A basket transfer and loading device includes a first loading mechanism and a second loading mechanism. Both the first loading mechanism and the second loading mechanism include a first translation part, a lifting part, a mounting seat, and a carrying platform, where:

[0006] The lifting part is connected to the movable part of the first translation part, the mounting seat is connected to the movable part of the lifting part, and the carrying platform is installed on the mounting seat;

[0007] The carrying platform is configured to carry a basket placed in the vertical direction;

[0010] The first loading mechanism and the second loading mechanism are configured to alternately move the basket containing sheets to the input end of the sheet conveyor line. The sheet conveyor line is configured to take out sheets from the basket one by one and convey the sheets to the subsequent process station.

[0011] In the basket transfer and loading device of this application, the first loading mechanism and the second loading mechanism alternately load sheets onto the sheet conveyor line. In this way, when one of them is performing the basket replacement operation, the other can continue to perform normal feeding of the sheet conveyor line, preventing feeding waiting and improving the feeding efficiency.

[0012] In some embodiments, the first feeding mechanism and the second feeding mechanism further include a second translation part disposed on the mounting base; the carrying platform is slidably connected to the mounting base and is in transmission connection with the second translation part; the second translation part is configured to drive the carrying platform to slide along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the material basket includes one storage cavity or two storage cavities. When the material basket includes two storage cavities, the two storage cavities in the material basket located on the carrying platform are arranged side by side along the second horizontal direction. When the second translation part drives the carrying platform to slide along the second horizontal direction, it is configured to drive the two storage cavities to be respectively docked with the input end of the sheet conveying line.

[0013] Both the first feeding mechanism and the second feeding mechanism can drive the material basket thereon to translate perpendicular to the sheet conveying line. Thus, when the material basket has one or more than two storage cavities, the storage cavities of the material basket can all be docked with the input end of the sheet conveying line, so as to realize the compatibility of the material basket turnover feeding device of the present application with material baskets of different structures.

[0014] In some embodiments, the first feeding mechanism and the second feeding mechanism further include a clamping part disposed on the carrying platform, and the clamping part is configured to clamp and position the material basket on the carrying platform.

[0015] By providing the clamping part, the material basket is clamped and positioned on the carrying platform, preventing the material basket from sliding during movement and causing position deviation.

The clamping part includes a mounting bracket, a pushing component and a pressing component, wherein: the mounting bracket is disposed on the carrying platform; the pushing component is disposed on the mounting bracket, and the pushing component is configured to push the material basket towards the stop block to cooperate with the stop block to press the bottom of the material basket; the pressing component is disposed on the mounting bracket, and the pressing component is configured to press down the top of the material basket.

[0017] Through the cooperation of the pushing component and the pressing component, the clamping part realizes the pressing of the bottom and the top of the material basket, thereby ensuring that the material basket is clamped and positioned on the carrying platform.

[0020] In some embodiments, the pressing assembly includes a fourth translation part and a pressing plate. The fourth translation part is disposed on the top of the mounting bracket, and the pressing plate is connected to the driving end of the fourth translation part. The fourth translation part is configured to drive the pressing plate to move toward or away from the top of the basket, so as to press down or release the top of the basket.

[0021] A pressing assembly with a simple structure is provided. The pressing plate is driven by the fourth translation part to move toward or away from the top of the basket, so as to press down or release the top of the basket.

[0022] In some embodiments, an avoidance opening is provided on the carrier table for avoiding the input end of the sheet conveying line.

[0023] The input end of the sheet conveying line is avoided, preventing collision between the carrier table and the input end of the sheet conveying line during the lifting and lowering process of the carrier table.

[0024] In some embodiments, when the basket on the carrier table of the first loading mechanism releases the sheets to the input end of the sheet conveying line, the carrier table of the second loading mechanism drives the basket loaded with sheets to move directly above the carrier table of the first loading mechanism; during the process of the basket on the carrier table of the first loading mechanism releasing the sheets to the input end of the sheet conveying line, the carrier table of the second loading mechanism gradually descends; after the basket on the carrier table of the first loading mechanism finishes releasing all the sheets in the current storage cavity, the carrier table of the second loading mechanism descends to the release position to release the sheets to the input end of the sheet conveying line.

[0025] The sheet conveying line can continuously and cyclically pick up the sheets in the first basket on the first transfer mechanism and the second basket on the second transfer mechanism, thereby further improving the sheet loading efficiency.

[0026] In some embodiments, the basket transfer and loading device further includes a basket output part and a basket receiving part; the basket output part provides a basket loaded with sheets to the carrier table, and the first translation part is configured to drive the carrier table to translate the basket loaded with sheets along the first horizontal direction to the input end of the sheet conveying line; the carrier table translates the basket emptied of sheets to the position of the basket receiving part along the first horizontal direction under the drive of the first translation part.

[0027] After the carrier table translates the basket emptied of sheets to the position of the basket receiving part, it immediately receives the basket loaded with sheets provided by the basket output part, thereby improving the basket changing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] As Figure 1 shown, the material basket transfer and loading device in the embodiments of the present application includes a first loading mechanism 1 and a second loading mechanism 2. Both the first loading mechanism 1 and the second loading mechanism 2 include a first translation part 11, a lifting part 12, a mounting seat 13, and a carrying platform 14, wherein:

[0038] The lifting part 12 is connected to the moving part of the first translation part 11, the mounting seat 13 is connected to the moving part of the lifting part 12, and the carrying platform 14 is installed on the mounting seat 13.

[0039] The carrying platform 14 is configured to carry the material basket 100 placed in the vertical direction.

[0040] The first translation part 11 is configured to drive the carrying platform 14 to move towards or away from the sheet conveying line 3 along the first horizontal direction (for example, the X-axis direction). The conveying direction of the sheet conveying line 3 is parallel to the first horizontal direction.

[0041] The lifting part 12 is configured to drive the carrying platform 14 to lift.

[0042] The first loading mechanism 1 and the second loading mechanism 2 are configured to alternately move the material basket 100 filled with sheets to the input end of the sheet conveying line 3. The sheet conveying line 1 is configured to take out sheets from the material basket one by one and convey the sheets to the subsequent process station.

[0043] In the wafer basket transfer and loading device provided by the embodiment of the present application, the first loading mechanism 1 and the second loading mechanism 2 alternately load wafers onto the wafer transfer line 3. In this way, when one of them is performing the basket replacement operation, the other can continue to perform normal loading onto the wafer transfer line 3, preventing loading waiting and improving the loading efficiency.

[0044] The loading processes of the first loading mechanism 1 and the second loading mechanism 2 are the same. Taking the first loading mechanism 1 as an example, the optional loading process is as follows:

[0045] The lifting part 12 drives the carrier 14 to lift and lower, so that the carrier 14 is aligned with the wafer basket output part arranged at the basket replacement position. The first translation part 11 drives the carrier 14 to move to the side of the wafer basket output part. The wafer basket output part outputs the wafer basket filled with wafers to the carrier 14 in a vertical state.

[0046] Subsequently, the lifting part 12 drives the carrier 14 to lift and lower, so that the wafer basket is aligned with the wafer transfer line 3. The first translation part 11 drives the carrier 14 to move towards the wafer transfer line 3 until the input end of the wafer transfer line 3 is inserted into the wafer basket.

[0047] Then, the lifting part 12 drives the carrier 14 and the wafer basket to descend, so that the wafers in the wafer basket can fall onto the input end of the wafer transfer line 3 in sequence and are taken out by the wafer transfer line 3 in sequence and then conveyed to the subsequent process station.

[0048] When the wafer basket is emptied, the first translation part 11 drives the carrier 14 to move away from the wafer transfer line 3, so that the input end of the wafer transfer line 3 is withdrawn from the emptied wafer basket. Subsequently, the lifting part 12 controls the carrier 14 to lift and lower, so that the carrier 14 is aligned with the wafer basket receiving part arranged at the basket replacement position.

[0049] The first translation part 11 drives the carrier 14 to move to the side of the wafer basket receiving part, and the wafer basket receiving part receives the emptied wafer basket from the carrier 14.

[0050] The wafer basket transfer and loading device of the embodiment of the present application is suitable for loading the wafers in the wafer basket onto the wafer transfer line 3. In this application scenario, the wafer is the silicon wafer, and the wafer transfer line 3 is the silicon wafer transfer line. Of course, the wafer basket transfer and loading device provided by the embodiment of the present application is also suitable for loading other types of sheet-like articles.

[0051] Such as Figures 2 to 3As shown, optionally, the first feeding mechanism 1 and the second feeding mechanism 2 further include a second translation part 15 arranged on the mounting base 13. The carrying platform 14 is slidably connected to the mounting base 13 and is in transmission connection with the second translation part 15. The second translation part 15 is configured to drive the carrying platform 14 to slide along the second horizontal direction (for example, the Y-axis direction), and the second horizontal direction is perpendicular to the first horizontal direction. The basket includes one storage cavity or two storage cavities.

[0052] When the basket only includes one storage cavity, the second translation part 15 drives the carrying platform 14 to slide along the second horizontal direction, so that the storage cavity can be docked with the sheet conveying line 3, so that the sheet conveying line 3 can take out the sheets in the storage cavity.

[0053] When the basket includes two storage cavities, the two storage cavities in the basket located on the carrying platform 14 are arranged side by side along the second horizontal direction. When the second translation part 15 drives the carrying platform 14 to slide along the second horizontal direction, the two storage cavities can be respectively docked with the sheet conveying line 3, so that the sheet conveying line 3 can successively take out the sheets in the two storage cavities.

[0054] As Figures 2 to 3 shown, optionally, the first feeding mechanism 1 and the second feeding mechanism 2 further include a clamping part 17 arranged on the carrying platform 14. The clamping part 17 is configured to clamp and position the basket on the carrying platform 14 to prevent the basket from sliding and generating position deviation during the movement.

[0055] Optionally, a stop block 16 is arranged at the end of the carrying platform 14 far away from the lifting part 12. The clamping part 17 includes a mounting bracket 171, a pushing component 172 and a pressing component 173, wherein: the mounting bracket 171 is arranged on the carrying platform 14. The pushing component 172 is arranged on the mounting bracket 171. The pushing component 172 is configured to push the basket towards the stop block 16 to cooperate with the stop block 16 to press the bottom of the basket. The pressing component 173 is arranged on the mounting bracket 171. The pressing component 173 is configured to press the top of the basket downwards.

[0056] Optionally, the pushing component 172 includes a third translation part 1721 and a pushing plate 1722. Among them, the third translation part 1721 is arranged at the bottom of the mounting bracket 171, and the pushing plate 1722 is connected to the driving end of the third translation part 1721. The third translation part 1721 is used to drive the pushing plate 1722 to move towards or away from the bottom of the basket to cooperate with the stop block 16 to press or release the bottom of the basket. The third translation part 1721 can be a cylinder.

[0057] Optionally, the pressing assembly 173 includes a fourth translation part 1731 and a pressing plate 1732. Among them, the fourth translation part 1731 is arranged on the top of the mounting bracket 171, and the pressing plate 1732 is connected to the driving end of the fourth translation part 1731. The fourth translation part 1731 is used to drive the pressing plate 1732 to move towards or away from the top of the basket, so as to press down or release the top of the basket. The fourth translation part 1731 can be a cylinder.

[0058] As Figure 3 shown, optionally, an avoidance opening 18 for avoiding the input end of the sheet conveying line 3 is provided on the bearing table 14. The avoidance opening 18 realizes the avoidance of the input end of the sheet conveying line 3, and prevents the bearing table 14 from colliding with the input end of the sheet conveying line 3 during the lifting and lowering process.

[0059] Optionally, when the basket on the bearing table 14 of the first feeding mechanism 1 releases the sheet to the input end of the sheet conveying line 3, the bearing table 14 of the second feeding mechanism 2 drives the basket loaded with the sheet to move directly above the bearing table 14 of the first feeding mechanism 1. During the process that the basket on the bearing table 14 of the first feeding mechanism 1 releases the sheet to the input end of the sheet conveying line 3, the bearing table 14 of the second feeding mechanism 2 gradually descends. After the basket on the bearing table 14 of the first feeding mechanism 1 finishes releasing all the sheets in the current storage cavity, the bearing table 14 of the second feeding mechanism 2 descends to the release position to release the sheet to the input end of the sheet conveying line 3.

[0060] For a basket with only one storage cavity, the optional cooperative feeding process of the first feeding mechanism 1 and the second feeding mechanism 2 is as follows:

[0061] The first feeding mechanism 1 drives the first basket located thereon to lift and translate, so that the input end of the sheet conveying line 3 is inserted into the storage cavity of the first basket. Subsequently, the first feeding mechanism 1 drives the first basket to descend, so that the sheets in the first basket fall onto the input end of the sheet conveying line 3 in sequence and are taken out by the sheet conveying line 3.

[0062] The second feeding mechanism 2 drives the second basket located thereon to lift and translate, so that the second basket on the second feeding mechanism 2 moves above the first basket and ensures that the storage cavity of the second basket is aligned with the storage cavity of the first basket up and down.

[0063] While the first basket descends to release the sheet, the second basket also descends synchronously.

[0064] After the sheets in the first basket are emptied, the first feeding mechanism 1 drives the first basket away from the input end of the sheet conveying line 3. The second basket continues to descend, causing the input end of the sheet conveying line 3 to insert into the receiving cavity of the second basket. Subsequently, the second feeding mechanism 2 drives the second basket to descend, so that the sheets in the second basket sequentially fall onto the input end of the sheet conveying line 3 and are taken out by the sheet conveying line 3.

[0065] After the first feeding mechanism 1 completes the basket-changing operation and obtains a new first basket filled with sheets, the first feeding mechanism 1 drives the first basket located thereon to move, so that the first basket moves above the second basket that is currently releasing sheets, and ensures that the receiving cavity of the first basket is vertically aligned with the receiving cavity of the second basket.

[0066] It can be seen that the sheet conveying line 3 realizes the continuous and cyclic sheet taking of the sheets in the first basket with only one receiving cavity on the first feeding mechanism 1 and the second basket with only one receiving cavity on the second feeding mechanism 2, thereby improving the sheet feeding efficiency.

[0067] In summary, when one of the baskets releases sheets, the other basket filled with sheets will synchronously descend above it to wait for replacement. The distance between the two baskets is very short. When one of the baskets is emptied, the other basket filled with sheets only needs to descend a very short distance to be in place for replacement and continue to release sheets. Therefore, the basket-changing time is very short and the efficiency is very high.

[0068] For the basket with two receiving cavities, the optional feeding process of the first feeding mechanism 1 and the second feeding mechanism 2 is as follows:

[0069] The first feeding mechanism 1 drives the first basket with sheets in both of its two receiving cavities to lift and translate, so that the input end of the sheet conveying line 3 inserts into the first receiving cavity of the first basket. Subsequently, the first feeding mechanism 1 drives the first basket to descend, so that the sheets in the first receiving cavity of the first basket sequentially fall onto the input end of the sheet conveying line 3 and are taken out by the sheet conveying line 3.

[0070] The second feeding mechanism 2 drives the second basket with sheets in both of its two receiving cavities to lift and translate, so that the second basket on the second feeding mechanism 2 moves above the first basket, and ensures that the first receiving cavity of the second basket is vertically aligned with the first receiving cavity of the first basket, the second receiving cavity of the second basket is vertically aligned with the second receiving cavity of the first basket, and the second basket and the first basket descend synchronously.

[0071] After the sheets in the first storage cavity of the first material basket are emptied, the first feeding mechanism 1 drives the first material basket away from the input end of the sheet conveying line 3, and the second material basket continues to descend, so that the input end of the sheet conveying line 3 is inserted into the first storage cavity of the second material basket. Subsequently, the second feeding mechanism 2 drives the second material basket to descend, so that the sheets in the first receiving cavity of the second material basket fall onto the input end of the sheet conveying line 3 in sequence and are taken out by the sheet conveying line 3.

[0072] Meanwhile, the first feeding mechanism 1 drives the first material basket to rise and translate. The second translation part 15 in the first feeding mechanism 1 drives the carrier table 14 to slide along the second horizontal direction, so that the first material basket moves above the second material basket that is currently releasing sheets, and ensures that the second storage cavity of the first material basket is vertically aligned with the first storage cavity of the second material basket.

[0073] After the sheets in the first storage cavity of the second material basket are emptied, the second feeding mechanism 2 drives the second material basket away from the input end of the sheet conveying line 3, and the first material basket continues to descend, so that the input end of the sheet conveying line 3 is inserted into the second storage cavity of the first material basket. Subsequently, the first feeding mechanism 1 drives the first material basket to descend, so that the sheets in the second receiving cavity of the first material basket fall onto the input end of the sheet conveying line 3 in sequence and are taken out by the sheet conveying line 3.

[0074] Meanwhile, the second feeding mechanism 2 drives the second material basket to rise and translate. The second translation part 15 in the second feeding mechanism 2 drives the carrier table 14 to slide along the second horizontal direction, so that the second material basket moves above the first material basket that is currently releasing sheets, and ensures that the second storage cavity of the second material basket is vertically aligned with the second storage cavity of the first material basket.

[0075] After the sheets in the second storage cavity of the first material basket are emptied, the first feeding mechanism 1 drives the first material basket away from the input end of the sheet conveying line 3. The second material basket continues to descend, so that the input end of the sheet conveying line 3 is inserted into the second storage cavity of the second material basket, and the sheets in the second storage cavity of the second material basket are taken away by the sheet conveying line 3.

[0076] After the first feeding mechanism 1 completes the basket-changing operation and obtains a new first material basket filled with sheets, the first feeding mechanism 1 drives the first material basket located thereon to move, so that the first material basket on the first feeding mechanism 1 moves above the second material basket that is currently releasing sheets, and ensures that the first storage cavity of the first material basket is vertically aligned with the second storage cavity of the second material basket.

[0077] It can be seen that the sheet conveying line 3 realizes continuous and cyclic sheet taking from the first material basket with two storage cavities on the first feeding mechanism 1 and the second material basket with two storage cavities on the second feeding mechanism 2, thereby improving the sheet feeding efficiency.

[0078] Optionally, the basket transfer and loading device in the embodiments of the present application further includes a basket output unit and a basket receiving unit. The basket output unit provides a basket containing sheets to the carrier table, and the first translation unit 11 is configured to drive the carrier table 14 to translate the basket containing sheets along a first horizontal direction to the input end of the sheet conveying line 3. The carrier table 14 translates the basket emptied of sheets to the position of the basket receiving unit along the first horizontal direction under the drive of the first translation unit 11.

[0079] With such a setting, after the carrier table 14 translates the basket emptied of sheets to the position of the basket receiving unit, it immediately receives the basket containing sheets provided by the basket output unit, thereby improving the basket changing efficiency.

[0080] The above description of the present application is detailed enough and has a certain particularity. Those of ordinary skill in the art should understand that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the protection scope of the present application. The scope of protection required by the present application is defined by the claims described, rather than by the above description in the embodiments.
