Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic cell production equipment, in particular to a pressing device conveying device and a cell string welding equipment. BACKGROUND

[0002] In the production process of photovoltaic modules, the string welding of cell pieces and welding strips is an important process. In this process, the welding strip is laid on the cell piece, and the complete circuit is formed by welding. In order to ensure the accurate position of the welding strip, a pressing device is placed to press the welding strip after the welding strip is laid on the cell piece, and then conveyed to the welding station for welding.

[0003] The traditional string welding method is to place one cell piece on the welding conveying device each time, then lay a group of welding strips on it, and pick up one pressing device from the pressing device conveying device to press the welding strip.

[0004] With the progress of technology, the new string welding process allows two or more cell pieces to be placed on the welding conveying device at the same time, and the welding strip is laid on each cell piece at the same time, which requires multiple pressing devices to be simultaneously transported to meet the welding strip fixing requirements of each cell piece. The spacing between the simultaneously transported pressing devices needs to meet the welding requirements. However, the pressing devices on the existing pressing device conveying device are continuously conveyed, that is, the pressing devices are tightly attached to each other, which cannot meet the spacing requirements of the new string welding process for the pressing devices, so that multiple pressing devices with required spacing cannot be directly picked up from the pressing device conveying device at the same time. CONTENT OF THE INVENTION

[0005] (1) The problem to be solved by the present application is that the existing pressing device conveying device continuously conveys the pressing devices to the conveying device, and the pressing devices are tightly attached to each other, which cannot meet the spacing requirements of the new string welding process for the pressing devices.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the pressing device conveying device provided by the present application comprises a conveying line for conveying the pressing devices; the pressing device conveying device further comprises a supporting assembly and a driving assembly;

[0008] The supporting assembly is provided with n supporting assemblies, and the n supporting assemblies are arranged side by side on the conveying path of the conveying line. Each supporting assembly is used for supporting one pressing device, and n≥2;

[0009] The driving assembly is in transmission connection with each supporting assembly, and is used for driving each supporting assembly to ascend and descend in the vertical direction, so as to lift the n continuous pressing devices on the conveying line away from the conveying surface of the conveying line. The driving assembly is also used for driving each supporting assembly to move in a first direction, so as to implement the spacing of the pressing devices carried on each supporting assembly. The first direction is parallel to the length direction of the conveying line.

[0010] In use, the driving assembly first drives the supporting assembly to move in the vertical direction, so that the n continuously conveyed pressing tools are lifted by the supporting assembly away from the conveying surface of the conveying line; after the supporting assembly lifts the pressing tools, the driving assembly continues to act, and the driving assembly drives each supporting assembly to move in the first direction, so as to implement distance separation of the pressing tools carried on each supporting assembly. Compared with the prior art, the n continuously conveyed pressing tools are distance separated by the driving assembly and the supporting assembly, so that the n pressing tools that are closely arranged in sequence are separated, and the distance separation requirement of the pressing tools in the new string welding process can be met.

[0011] Further, the two ends of the pressing tool extend out of the conveying surface of the conveying line on the conveying line.

[0012] Each supporting assembly at least comprises a pair of oppositely arranged supporting members. The two supporting members are oppositely arranged on both sides of the conveying line and can support the parts of the pressing tool extending out of the conveying line to support the pressing tool.

[0013] The pressing tool on the conveying surface is lifted by supporting the two ends of the pressing tool extending out of the conveying line, so that the supporting assembly has greater flexibility, facilitating the arrangement of the supporting assembly, and being more convenient for maintenance, and ensuring the stability of the pressing tool when being lifted, reducing the risk of damage to the pressing tool or damage to other parts of the pressing tool conveying device due to falling during movement, and ensuring the long-term stable operation of the pressing tool conveying device.

[0014] Further, the supporting assembly further comprises a first power source.

[0015] The first power source is connected with the two supporting members and is used to drive the two supporting members to extend into or withdraw from below the parts of the pressing tool extending out of the conveying line.

[0016] When the n pressing tools on the conveying line are lifted and distance separated, the conveying line can continue to convey the subsequent pressing tools below the supporting assembly, waiting for the next distance separation. When the n pressing tools on the supporting assembly are distance separated and taken away, if the supporting members directly descend at this time, interference with the pressing tools below waiting for distance separation will occur. Therefore, by providing the first power source, the two supporting members are driven to move away from each other before the supporting members descend, and the supporting members are driven to extend below the pressing tools after the supporting members descend below the position of the pressing tools, so that interference between the supporting members and the pressing tools below during the descending process is avoided, and normal distance separation of the pressing tools is ensured.

[0017] Further, the pressing tool conveying device further comprises n alignment assemblies, and the alignment assemblies are arranged one by one on the supporting assemblies and are used to align the positions of the pressing tools supported by the supporting assemblies.

[0018] The alignment assembly aligns the positions of the pressing tools lifted by the supporting assembly, so that the pressing tools are directly laid on the welding ribbons to be pressed after being picked up by the subsequent mechanism, the quality of the battery string is ensured, and the production efficiency is improved.

[0019] Further, each of the returning assemblies comprises a pushing member, a blocking member and a second power source;

[0020] In the same pair of the two supporting members, one of the supporting members is movably provided with the pushing member above the supporting surface, and the other of the supporting members is fixedly provided with the blocking member above the supporting surface, and the pushing member and the blocking member are oppositely arranged;

[0021] The second power source is connected with the pushing member and drives the pushing member to move in the second direction to clamp or release the corresponding pressing tool between the pushing member and the blocking member, and the second direction is perpendicular to the first direction.

[0022] A returning assembly with simple structure is provided, and the pressing tool is pushed to the blocking member by the pushing member and is tightly abutted, so that the position returning of the pressing tool is completed.

[0023] Further, one end or both ends of the pressing tool is provided with a positioning groove on the side wall, and at least one of the blocking member and the pushing member is provided with a positioning ridge corresponding to the positioning groove, and when the pressing tool is clamped between the pushing member and the blocking member, the positioning ridge is inserted into the positioning groove on the same side.

[0024] When the second power source drives the pushing member to move in the second direction to clamp the pressing tool between the pushing member and the blocking member, the positioning ridge is simultaneously inserted into the positioning groove, the horizontal direction rotation returning of the pressing tool is realized, the returning effect of the returning assembly on the position of the pressing tool is improved, the position and angle of the pressing tool meet the carrying requirements of the subsequent carrying device, and the production efficiency is improved.

[0025] Further, the positioning groove is a V-shaped groove or a semicircular groove; and / or, the positioning ridge is spherical.

[0026] The positioning groove is provided in a V shape or a semicircular shape, and the positioning ridge is provided in a spherical structure, so that the insertion of the positioning ridge is facilitated, the angle returning of the pressing tool is quickly completed, and the spherical structure of the positioning ridge can also reduce the friction between the positioning ridge and the pressing tool in the process of picking up the pressing tool from the supporting assembly by the subsequent carrying mechanism.

[0027] Further, the driving assembly comprises a translation driving assembly and a lifting driving assembly which are connected with each other, wherein:

[0028] The translation driving assembly is provided with one, and each of the supporting assemblies is connected with the translation driving assembly, and the translation driving assembly is used to drive each of the supporting assemblies to move synchronously in the first direction;

[0029] Or, the translation driving assembly is provided with n and corresponds to the supporting assemblies one by one, the translation driving assembly is connected with the corresponding supporting assembly, and each of the translation driving assemblies is used to independently drive the corresponding supporting assembly to move in the first direction.

[0030] When the translation driving assembly is one-to-one corresponding to the supporting assembly, the device has stronger applicability.

[0031] Further, the press conveying device further comprises a detection mechanism and a controller.

[0032] The detection mechanism is configured to detect position information of the n presses to be separated on the conveying line.

[0033] The controller is configured to control the driving assembly to drive each supporting assembly to move to the corresponding position of the press and implement separation of the press based on the detection information of the detection mechanism.

[0034] By means of the detection mechanism and the controller, the driving assembly can automatically control the supporting assembly to implement separation of the press, and the device has the characteristics of high efficiency and high precision.

[0035] Further, the press conveying device further comprises a blocking mechanism.

[0036] The blocking mechanism comprises two blocks oppositely arranged along the second direction, and the two blocks are arranged on the conveying path of the conveying line and are configured to block the presses on the conveying line from continuing to move forward. Each supporting assembly is arranged close to the blocking mechanism and is configured to implement separation of the first n presses blocked by the blocking mechanism.

[0037] The blocking surface of the block further comprises a magnetic member configured to adsorb the press after the press contacts the blocking surface of the block to prevent the press from rebounding.

[0038] After the blocking mechanism blocks the presses, the driving assembly cooperates with the supporting assembly to implement separation of the first n presses on the conveying line, which can avoid the problem that the supporting assembly cannot hold the corresponding press due to the movement of the press, and can effectively improve the operation precision of the supporting assembly. Meanwhile, the blocking mechanism can also make the connected presses close to each other, which facilitates positioning of the presses.

[0039] Further, the press conveying device further comprises a transfer table arranged close to the supporting assembly and located on the movement path of the supporting assembly. The driving assembly is further configured to drive the supporting assembly to place the separated n presses on the transfer table.

[0040] After the separated n presses are placed on the transfer table, the driving assembly can drive the supporting assembly to reset without waiting for the press handling device to handle the presses, which is high in production efficiency.

[0041] Another aspect of the embodiment of the present application also provides a battery string welding device, which comprises a press handling device, a welding conveying device and the above-described press conveying device. The press handling device is configured to pick up the separated n presses from each supporting assembly or from the transfer table and synchronously handle the n presses to the welding conveying device.

[0042] The pressing tool conveying device can complete the spacing of the pressing tools before the pressing tool carrying device carries the pressing tools, can meet the spacing requirements of the new string welding process for the pressing tools, and is higher in production efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0071] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0072] The embodiment of the present application provides a pressing tool conveying device, which is used for conveying a pressing tool 2, and the pressing tool 2 is used for being placed on a battery piece to press a welding strip when the battery piece is welded with the welding strip, so as to avoid dislocation of the welding strip in the conveying process of the battery piece.

[0073] Optionally, the pressing tool 2 comprises a frame 21 and a plurality of pressing needle rows arranged on the frame 21, each of the pressing needle rows comprises a plurality of pressing needles arranged in a straight line, and each of the pressing needle rows is configured to press one welding strip.

[0074] As Figures 1 to 11As shown, the press conveying device provided by the embodiment of the present application comprises a conveying line 1, a supporting assembly 3 and a driving assembly 4. The conveying line 1 is used for conveying the press 2. The supporting assembly 3 is provided with n (for example, 2 or 3) supporting members 31, and the n supporting members 31 are arranged side by side along the conveying path of the conveying line 1. Each supporting assembly 3 is used for supporting one press 2, that is, the n supporting assemblies 3 support the n presses 2 on the conveying line 1, and n≥2. The driving assembly 4 is in driving connection with each supporting assembly 3. The driving assembly 4 is used for driving each supporting assembly 3 to move vertically, so as to lift the n continuously conveyed presses 2 on the conveying line 1 and make the n continuously conveyed presses 2 move away from the conveying surface 11 of the conveying line 1. In addition, the driving assembly 4 is also used for driving each supporting assembly 3 to move in a first direction which is parallel to the length direction of the conveying line 1, so as to implement the spacing of the supporting assemblies 3, and further make the presses 2 carried on the supporting assemblies 3 be spaced. Figure 1 Figure 9

[0075] Optionally, the conveying line 1 comprises a driving motor and two conveying belts which are in driving connection with the driving motor and are arranged at intervals. Two driving motors can be arranged, and the two driving motors are respectively used for driving one conveying belt to run synchronously. Alternatively, one driving motor can be arranged, and the two conveying belts are driven by the one driving motor to run synchronously. The two conveying belts are respectively used for carrying the frames 21 of the presses 2 at two ends, and the press needle arrays on the frames 21 are located between the two conveying belts. By arranging the two conveying belts, the interference between the press needle arrays of the press 2 and the conveying belts during the conveying of the press 2 can be avoided.

[0076] The optional working process of the press conveying device provided by the embodiment of the present application is as follows: the upstream equipment conveys a plurality of presses 2 to the conveying line 1 in sequence, and the conveying line 1 conveys the presses 2 in sequence. When the n continuously conveyed presses 2 are conveyed to the n supporting assemblies 3 by the conveying line 1, the driving assembly 4 is actuated. The driving assembly 4 first drives the supporting assemblies 3 to move vertically, each supporting assembly 3 can lift one press 2, so that the n continuously conveyed presses 2 move away from the conveying surface 11 of the conveying line 1. After the supporting assemblies 3 lift the presses 2, the driving assembly 4 continues to actuate, and the driving assembly 4 drives the supporting assemblies 3 to move in the first direction, so as to implement the spacing of the presses 2 carried on the supporting assemblies 3. After the n continuously conveyed presses 2 are spaced, the spacing between the presses 2 meets the conveying requirement of the press conveying device 91. Therefore, the n presses 2 after the spacing can be conveyed to the subsequent process by the press conveying device 91. Compared with the prior art, the n continuously conveyed presses 2 are spaced by the driving assembly 4 and the supporting assemblies 3, so that the n presses 2 which are closely arranged in sequence are separated, and the spacing requirement of the new series welding process for the presses 2 can be met.

[0077] Figure 1 Figure 2 Figure 9 ​​​​​and Figure 10 As shown, optionally, when the press 2 is transported to the conveying line 1 by the upstream device, the two ends of the press 2 extend out of the conveying surface 11 of the conveying line 1, so that the supporting assembly 3 can support the press 2 on the conveying surface 11 by supporting the two ends of the press 2 extending out of the conveying line 1. This supporting manner makes the supporting assembly 3 more flexible, facilitates the arrangement of the supporting assembly 3, and is more convenient for maintenance. Each supporting assembly 3 includes at least a pair of oppositely arranged supporting members 31. The two supporting members 31 are arranged on the two sides of the conveying line 1 and are oppositely arranged. The two supporting members 31 support the portions of the press 2 extending out of the conveying line 1 at the two ends to support the press 2. By arranging the two supporting members 31 and supporting the press 2 by supporting the portions of the press 2 extending out of the conveying surface 11 at the two ends, the stability of the press 2 when being supported can be ensured, the risk of damage to the press 2 or other components of the press conveying device due to falling of the press 2 during movement can be reduced, and the long-term stable operation of the press conveying device can be ensured.

[0078] Optionally, in an embodiment, as shown in Figure 1 and Figure 2 As shown, after the supporting assembly 3 supports the n presses 2 on the conveying line 1 to be separated from the conveying surface 11, the conveying line 1 immediately conveys the subsequent press 2 under the supporting assembly 3 to wait for the next separation. When the n presses 2 supported by the supporting assembly 3 are taken away (i.e., the subsequent press conveying device 91 directly picks up the n presses 2 separated from each supporting assembly 3), if the supporting members 31 directly descend, interference with the press 2 waiting for separation below will occur. In order to solve this problem, as shown in Figures 2 to 4 The supporting assembly 3 further includes a first power source 32 connected with the two supporting members 31. The first power source 32 is used to drive the two supporting members 31 to extend into or exit the portions of the press 2 extending out of the conveying line 1 at the two ends. Specifically, the first power source 32 is used to drive the two supporting members 31 to move towards or away from each other. Before the supporting assembly 3 supports the press 2 on the conveying surface 11, the first power source 32 needs to drive the two supporting members 31 to move towards each other, so that the two supporting members 31 extend into the portions of the press 2 extending out of the conveying line 1 at the two ends. When the press 2 on the supporting assembly 3 is taken away by the subsequent press conveying device 91, the first power source 32 drives the two supporting members 31 to move away from each other, so that the two supporting members 31 are reset to be away from the portions of the press 2 extending out of the conveying line 1 at the two ends. After the two supporting members 31 are lowered to be below the position of the press 2 below, the first power source 32 drives the supporting members 31 to extend into the press 2 below, so that the next separation can be performed, avoiding the interference of the supporting members 31 with the press 2 below during the descending process, and ensuring the normal performance of the next separation of the press 2.

[0079] Optionally, in another embodiment, as shown in Figure 9 andFigure 10 As shown, the press conveying device further comprises a transfer table 8, which is arranged close to the supporting assembly 3 and located on the moving path of the supporting assembly 3, and the driving assembly 4 is further used to drive the supporting assembly 3 to place the n presses 2 after being separated on the transfer table 8. The transfer table 8 is used to buffer the n presses 2 after being separated, and the press handling device 91 in the subsequent process picks up the n presses 2 after being separated from the transfer table 8.

[0080] In use, the driving assembly 4 first drives the n supporting assemblies 3 to move in the vertical direction, so that the supporting assemblies 3 can lift the n presses 2 on the conveying surface 11; then the conveying line 1 can convey the subsequent presses 2 to wait for the next time of separation, and at the same time, the driving assembly 4 drives the supporting assemblies 3 to move in the first direction, so that the supporting assemblies 3 move to the transfer table 8 while the presses 2 are separated; after the supporting assemblies 3 move above the transfer table 8, the driving assembly 4 drives the supporting assemblies 3 to move downward in the vertical direction, so that the n presses 2 after being separated are placed on the transfer table 8; since the supporting assemblies 3 are located at the transfer table 8 at this time, the supporting assemblies 3 are away from the n presses 2 to be separated next time, so that the supporting assemblies 3 can directly move to the low position after being lowered at the transfer table 8, and then return to below the n presses 2 to be separated next time in the first direction, so that it is not necessary to set the first power source 32 to control the two supporting members 31 to approach or be away from each other, and the two supporting members 31 can be relatively fixedly arranged.

[0081] Optionally, when the supporting assembly 3 comprises the first power source 32, each supporting member 31 can be provided with one first power source 32, and at this time, the first power source 32 can be a combination of a pneumatic cylinder, an electric cylinder or a motor, a gear and a rack, and the first power source 32 drives the corresponding supporting member 31 to move; or one pair of supporting members 31 can share one first power source 32, and at this time, the first power source 32 can be a combination of a double-head pneumatic cylinder, a double-head electric cylinder or a motor, a gear and a rack with two toothed surfaces arranged opposite to each other, and the first power source 32 drives the two supporting members 31 in the same pair to move synchronously.

[0082] Optionally, as shown in Figures 2 to 4 , and Figure 7 , Figure 8 , and Figure 11 , the press conveying device further comprises a normalizing assembly 5, and n normalizing assemblies 5 are arranged one by one on the supporting assembly 3; when the supporting assembly 3 lifts the press 2, the normalizing assembly 5 acts to normalize the position of the press 2 lifted by the supporting assembly 3, so as to facilitate the subsequent process and improve the production efficiency.

[0083] Continuing to refer to Figures 2 to 4 , and Figure 7 , Figure 8 , and Figure 11Each of the correcting assemblies 5 comprises a pushing member 52, a blocking member 53 and a second power source 51. The pushing member 52 and the blocking member 53 are in the form of blocks or plates, and are arranged above the supporting surface 311 of one of the two supporting members 31 of the same pair, and are oppositely arranged to achieve accurate centering. The second power source 51 is connected to the pushing member 52, and is used to drive the pushing member 52 to move in a second direction perpendicular to the first direction, so as to clamp or release the press 2 supported by the supporting assembly 3. Specifically, after the supporting assembly 3 supports the press 2, the second power source 51 drives the pushing member 52 to move towards the blocking member 53, so that the pushing member 52 contacts one end of the press 2 close to the pushing member 52, and pushes the press 2 to move towards the blocking member 53, so that the other end of the press 2 away from the pushing member 52 contacts the blocking member 53 and clamps the press 2, thereby correcting the position of the press 2. After the press 2 is corrected, when the later press conveying device 91 is ready to convey the press 2 from the supporting assembly 3, or when the supporting assembly 3 is ready to place the press 2 on the transfer table 8, the second power source 51 drives the pushing member 52 to move away from the blocking member 53, so that the pushing member 52 is separated from the one end of the press 2 close to the pushing member 52 to release the press 2, thereby enabling the press conveying device 91 to convey the press 2 on the supporting assembly 3, or enabling the supporting assembly 3 to release the press 2 on the transfer table 8. Optionally, the second power source 51 can be a pneumatic cylinder or an electric cylinder, or can be a combination of a motor, a gear and a rack, which can all achieve the purpose of driving the pushing member 52 to move in the second direction.

[0084] Optionally, as Figure 6 and Figure 7As shown, the supporting assembly 3 further comprises a support frame 33, which is a main supporting structure of the supporting assembly 3. The support frame 33 comprises a horizontal plate 332 and two vertical plates 331 respectively arranged at two ends of the horizontal plate 332, and the two vertical plates 331 are oppositely arranged. The support frame 33 is connected with the driving assembly 4. The two supporting members 31 are respectively arranged at one end of the two vertical plates 331 away from the horizontal plate 332. When the supporting assembly 3 further comprises the first power source 32, and the first power source 32 corresponds to the supporting member 31 one by one, the first power source 32 is also fixedly arranged on the vertical plate 331, and the vertical plate 331 can be provided with a sliding rail or other structure matched with the supporting member 31 to improve the moving stability of the supporting member 31. The supporting member 31 is at least partially in a plate structure to form a supporting surface 311. The second power source 51 is fixedly arranged on the vertical plate 331, the pushing member 52 and the blocking member 53 are respectively arranged above the supporting surface 311 of the two supporting members 31. Optionally, the pushing member 52 and the blocking member 53 can be arranged above the supporting surface 311 of the supporting member 31 through a bracket or other structure, and the pushing member 52 and the blocking member 53 are arranged in a spaced manner with the supporting surface 311 of the supporting member 31, or the supporting member 31 is slidingly arranged on the supporting surface 311 of one of the supporting members 31, and the blocking member 53 is fixedly arranged on the supporting surface 311 of the other supporting member 31. Optionally, when the pushing member 52 is slidingly arranged on the supporting surface 311, a sliding groove or other structure can be arranged on the supporting surface 311 to match with the pushing member 52 to improve the stability of the pushing member 52 during movement.

[0085] Optionally, as Figures 2 to 4 , and Figure 7 , Figure 8 and Figure 11As shown, in order to improve the alignment effect of the alignment assembly 5 on the position of the press 2, one or both ends of the frame 21 of the press 2 are provided with positioning grooves 211, and at least one of the blocking piece 53 and the pushing piece 52 is provided with a positioning ridge 54 corresponding to the positioning groove 211. The positioning groove 211 and the positioning ridge 54 are arranged in pairs, that is, if only one end of the frame 21 of the press 2 is provided with a positioning groove 211 on the side wall, and the other end of the side wall is a flat surface, only the pushing piece 52 or the blocking piece 53 adjacent to the positioning groove 211 is provided with a positioning ridge 54, and the pushing piece 52 or the blocking piece 53 adjacent to the flat surface is provided with a positioning flat surface. For example, when the press 2 is on the conveying line 1, if the side wall of the frame 21 of the press 2 provided with the positioning groove 211 is close to the pushing piece 52, only the pushing piece 52 is provided with the positioning ridge 54; when the press 2 is on the conveying line 1, if the side wall of the frame 21 of the press 2 provided with the positioning groove 211 is close to the blocking piece 53, only the blocking piece 53 is provided with the positioning ridge 54; if the side walls of both ends of the frame 21 of the press 2 are provided with the positioning groove 211, the pushing piece 52 and the blocking piece 53 are both provided with the positioning ridge 54. When the second power source 51 drives the pushing piece 52 to move in the second direction to clamp the press 2 between the blocking piece 53 and the pushing piece 52, the positioning ridge 54 is inserted into the positioning groove 211 at the same time, realizing the horizontal rotation alignment of the press 2, improving the alignment effect of the alignment assembly 5 on the position of the press 2, and making the position and angle of the press 2 meet the requirements of the subsequent stringing, thereby improving the production efficiency. Optionally, the number of positioning grooves 211 provided on one end of the side wall of the frame 21 is at least one. Optionally, in order to improve the accuracy of positioning and reduce the processing difficulty, the number of positioning grooves 211 provided on one end of the side wall of the frame 21 is two.

[0086] Optionally, as shown in Figures 2 to 4 , Figure 7 , Figure 8 and Figure 11 , the positioning groove 211 can be a V-shaped groove or a semicircular groove. The positioning ridge 54 can be in a spherical structure or a similar arc surface structure (such as a V-shaped structure with an arc surface tip). When the positioning groove 211 is arranged in a V-shaped or semicircular shape, the insertion of the positioning ridge 54 can be facilitated, and the angle alignment of the press 2 can be quickly completed. The positioning ridge 54 arranged in a spherical structure can also facilitate the insertion of the positioning ridge 54, and can also reduce the friction between the positioning ridge 54 and the press 2 during the process of picking up the press 2 from the supporting assembly 3 by the subsequent press handling device 91.

[0087] Optionally, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the driving assembly 4 comprises a translation driving assembly 41 and a lifting driving assembly 42 connected with each other, and the supporting assembly 3 is connected with the translation driving assembly 41. In use, the translation driving assembly 41 drives the supporting assembly 3 to move in the first direction, and the lifting driving assembly 42 drives the translation driving assembly 41 and the supporting assembly 3 to move in the vertical direction. In an alternative arrangement of the driving assembly 4, one translation driving assembly 41 is arranged, and each supporting assembly 3 is connected with the translation driving assembly 41, and the translation driving assembly 41 is configured to drive each supporting assembly 3 to move in the first direction synchronously. This arrangement is suitable for the pressing tools 2 with the same size. In use, when the n pressing tools 2 are conveyed to the supporting assemblies 3 and are tightly attached to each other, since the n pressing tools 2 have the same size, the initial supporting position of each supporting assembly 3 when supporting the pressing tool 2 is the same, and thus each supporting assembly 3 can be driven by the translation driving assembly 41 to move in the first direction synchronously to the position below the corresponding pressing tool 2, and then the lifting driving assembly 42 drives the translation driving assembly 41 and the supporting assembly 3 connected with the translation driving assembly 41 to move upward, so that the supporting assembly 3 can support the corresponding pressing tool 2; and then the translation driving assembly 41 drives each supporting assembly 3 to move in the first direction to separate the n pressing tools 2.

[0088] In another alternative embodiment of the driving assembly 4, n translation driving assemblies 41 are arranged and correspond to the n supporting assemblies 3 respectively. Each translation driving assembly 41 is connected with the corresponding supporting assembly 3, and each translation driving assembly 41 is configured to independently drive the corresponding supporting assembly 3 to move in the first direction. This arrangement is suitable for the pressing tools 2 with the same size, and is more suitable for the pressing tools 2 with different sizes. For example, at least two different sizes of the n pressing tools 2 exist, because in actual production process, the welding strips on the upper side of the battery tab at the end of the battery string can be pressed by the large pressing tool 2, and the welding strips on the upper side of the remaining battery tab can be pressed by the small pressing tool 2. In use, when the n pressing tools 2 are conveyed to the supporting assemblies 3 and are tightly attached to each other, since at least two different sizes of the n pressing tools 2 exist, the initial supporting position of each supporting assembly 3 when supporting the pressing tool 2 varies according to the position of the large or small pressing tool 2, and thus each supporting assembly 3 can be independently driven by the corresponding translation driving assembly 41 to move in the first direction, so that the supporting assembly 3 can be accurately moved to the position below the corresponding pressing tool 2; then the lifting driving assembly 42 drives each translation driving assembly 41 and the supporting assembly 3 connected with the corresponding translation driving assembly 41 to move upward, so that the supporting assembly 3 can support the corresponding pressing tool 2; and then each translation driving assembly 41 drives the corresponding supporting assembly 3 to move in the first direction to separate the n pressing tools 2.

When the translation driving assembly 41 is provided with n and corresponds to the supporting assembly 3 one by one, as shown in Figure 3 each translation driving assembly 41 includes a first motor 411, a first gear 413 and a first rack 412, the first motor 411 is fixedly provided on the lifting driving assembly 42, the output shaft of the first motor 411 is in transmission connection with the first gear 413, the first rack 412 is engaged with the first gear 413, and the first gear 413 is connected with the support frame 33 of the corresponding supporting assembly 3; and a first sliding block 432 can also be provided on the support frame 33, and a first sliding rail 431 matched with the first sliding block 432 and extending in the first direction is provided on the driving end of the lifting driving assembly 42, so that the support frame 33 is slidingly connected to the lifting driving assembly 42, thereby improving the stability of the supporting assembly 3 when sliding in the first direction. In the embodiment, when the translation driving assembly 41 is provided with n and corresponds to the supporting assembly 3 one by one, the translation driving assembly 41 can also adopt a linear module, a cylinder or an electric cylinder, and the like, which can also achieve the purpose of driving the corresponding supporting assembly 3 to move in the first direction.

[0090] Optionally, as shown in Figure 5 and Figure 6 , the lifting driving assembly 42 includes a second motor 421, a screw-nut assembly, a lifting frame 422 and two oppositely arranged lifting plates 423. The lifting frame 422 is fixedly provided below the conveying line 1, the two lifting plates 423 are slidingly arranged on the lifting frame 422 through the cooperation of the second sliding block 434 provided thereon and the second sliding rail 433 provided on the lifting frame 422, the two lifting plates 423 are fixedly connected, the second motor 421 is fixedly provided on the lifting frame 422 and is in transmission connection with one of the lifting plates 423 through the screw-nut assembly. The second motor 421 drives the two lifting plates 423 to move synchronously through the screw-nut assembly.

[0091] Optionally, as shown in Figure 1 and Figure 9 , the press conveying device further includes a detection mechanism 6 and a controller. The detection mechanism 6 and the driving assembly 4 are electrically connected with the controller. The detection mechanism 6 is used for detecting the position information of the n press tools 2 to be spaced on the conveying line 1, and feeding the position information of the n press tools 2 to be spaced to the controller, and the controller controls the driving assembly 4 to drive each supporting assembly 3 to move to the position below the corresponding press tool 2 based on the detection information of the detection mechanism 6, and implements spacing for each press tool 2.

[0092] By setting the detection mechanism 6 and the controller, the driving assembly 4 can automatically control the supporting assembly 3 to operate to implement the distance between the pressing tools 2, which has the characteristics of high efficiency and high precision. Optionally, the detection mechanism 6 can adopt a visual detection system, or can be provided with n photoelectric sensors, or can be a combination of a visual detection system and n photoelectric sensors. The visual detection system includes a light source, a camera, an image processor and the like. The controller can be a central processing unit (CPU), a network processor (NP), etc.; or can be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, etc.

[0093] Optionally, as shown in Figure 2 、 Figure 9 、 Figure 10 and Figure 11 , the pressing tool conveying device further comprises a blocking mechanism 7, the blocking mechanism 7 comprises two blocking blocks 71 oppositely arranged along the second direction, and the two blocking blocks 71 are arranged on the conveying path of the conveying line 1 and used to block the pressing tools 2 on the conveying line 1 from continuing to convey forward. Each supporting assembly 3 is arranged close to the blocking mechanism 7 and used to implement the distance between the first n pressing tools 2 blocked by the blocking mechanism 7.

[0094] Optionally, the blocking mechanism 7 can be arranged at the output end of the conveying line 1 (as shown in Figure 2 ), or can be arranged at the middle part of the conveying line 1 (as shown in Figures 9 to 11 ), which can be selected according to actual conditions. After the blocking mechanism 7 blocks the pressing tools 2, the driving assembly 4 cooperates with the supporting assembly 3 to implement the distance between the first n pressing tools 2 on the conveying line 1, which can avoid the problem that the supporting assembly 3 cannot lift the corresponding pressing tools 2 due to the movement of the pressing tools 2, and can effectively improve the operation precision of the supporting assembly 3; at the same time, the blocking mechanism 7 can also make the connected pressing tools 2 close to each other, which is convenient for positioning the pressing tools 2.

[0095] Of course, if the pressing tool conveying device does not have the blocking mechanism 7, the n pressing tools 2 on the conveying line 1 can also be implemented by controlling the start and stop of the conveying line 1 to cooperate with the driving assembly 4 and the supporting assembly 3.

[0096] Optionally, in order to prevent the press 2 from rebounding after being stopped by the stop block 71, a magnetic member such as a permanent magnet or an electromagnet is arranged on the blocking surface of the stop block 71, and the frame 21 of the press 2 can be attracted by the magnetic member. When the press 2 contacts the blocking surface of the stop block 71, the frame 21 of the press 2 is attracted by the magnetic member, thereby preventing the press 2 from rebounding.

[0097] Based on the same application concept, as shown in Figure 12 the application also provides a battery string welding device, which comprises a press carrying device 91, a welding conveying device 92, and the press conveying device in any of the above embodiments. The press carrying device 91 is used to pick up the n presses 2 after being spaced apart from each other from each supporting assembly 3 or from the transfer table 8, and synchronously carry the n presses 2 to the welding conveying device 92.

[0098] The battery string welding device provided by the embodiments of the application is taken as an example in which each supporting assembly 3 corresponds to a translation driving assembly 41, and the blocking mechanism 7 is arranged at the end of the conveying line 1. The optional working process is as follows: the upstream device sequentially places a plurality of presses 2 on the conveying line 1, and the conveying line 1 sequentially conveys the presses 2 towards the blocking mechanism 7. When the first press 2 is stopped by the two stop blocks 71 of the blocking mechanism 7, the subsequent presses 2 are in close contact with the previous press 2. The detection mechanism 6 detects the position information of the front n presses 2 and feeds back to the controller, and the controller controls the n translation driving assemblies 41 to drive the corresponding supporting assemblies 3 to move in the first direction based on the detection information of the detection mechanism 6, and moves the supporting assemblies 3 to the positions below the corresponding presses 2; the first power source 32 drives the two supporting members 31 to move, so that the two supporting members 31 respectively extend below the two ends of the press 2; after the supporting assemblies 3 are moved to the positions, the controller controls the lifting driving assembly 42 to drive each translation driving assembly 41 and the supporting assembly 3 connected to the translation driving assembly 41 to move upwards, so that the supporting assemblies 3 lift the presses 2; after the supporting assemblies 3 lift the presses 2, the second power source 51 drives the pushing member 52 to move, the pushing member 52 contacts the end of the press 2 and pushes the press 2 to move towards the blocking member 53, so that the other end of the press 2 contacts the blocking member 53 and clamps the press 2, and the positioning ridge 54 extends into the positioning groove 211 to position the press 2 during the process in which the second power source 51 drives the pushing member 52 to push the press 2 to move; then, the translation driving assembly 41 drives the corresponding supporting assembly 3 to move in the first direction to space the presses 2 on each supporting assembly 3. After spacing, the press carrying device 91 picks up the n presses 2 after being spaced apart from each other from each supporting assembly 3, and synchronously carries the n presses 2 to the welding conveying device 92, so as to press the n groups of welding strips laid on the n battery plates on the welding conveying device 92 to the corresponding battery plates.
