Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, and particularly relates to a core feeding and positioning device. Background Art

[0002] In the technical field of battery manufacturing, the core feeding and positioning device plays a crucial role. It ensures that the core can be accurately placed at a preset position before being stacked into a module. This device plays a key role in maintaining the quality and performance of the battery module. Because only when the core is accurately positioned can displacement be avoided during the subsequent stacking process, ensuring the structural stability and electrical performance consistency of the battery module.

[0003] In the previous steps of core stacking, the core needs to be transported to a designated stacking working area. Usually, this transportation process is carried out on the tray through a conveyor line system. To ensure the stability of core stacking during battery manufacturing, we adopt the method of directly contacting the tray edge with a stop bar or a positioning arm to limit the movement of the tray and ensure it is stably located at the preset position. In addition, the tray is fixed by squeezing with a cylinder, which facilitates the clamping of the core on the tray by the fixture.

[0004] However, during this fixing process, the blocking of the tray by the stop bar and the pushing of the tray by the cylinder may introduce errors in the placement position. For example, if the conveyor line jitters during operation, it will cause the tray to shift after moving to the preset position. This shift will cause errors during the subsequent fixture clamping process, thus affecting the accuracy of core stacking and further affecting the quality and performance of battery module production. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model inserts a rectifying block into the hole of the limiting platform, and the pushing plate squeezes and positions the side of the tray. The specific technical solutions are as follows:

[0006] A core feeding and positioning device includes a conveyor line that transfers a transfer member carrying a core to a preset position, and a telescopic positioning member provided at the preset position. The telescopic positioning member presses and limits the transfer member. It further includes an auxiliary positioning member provided below the preset position. The auxiliary positioning member includes a blocking portion and a limiting portion provided at the preset position. The blocking portion blocks the transfer member from moving out of the preset position along the transfer direction. The limiting portion includes a part that can move vertically and is inserted into the bottom end of the transfer member.

[0007] In the above solution, the conveyor line moves the transfer part to a preset position. The blocking part fits or abuts against one side wall of the transfer part, restricting the transfer part at the preset position. The limiting part moves in the vertical direction, inserts into the bottom end of the transfer part, positioning the transfer part at the preset position. Under the push of the telescopic positioning part on the transfer part, the transfer part further fits against the part of the limiting part inserted into the transfer part, separating the transfer part from the conveyor line, effectively preventing the transfer part from shifting due to the conveyor line when the conveyor line moves the transfer part, ensuring the stability of the battery cell stacking and the quality of battery production.

[0008] Preferably, the transfer part includes a tray for carrying the battery cells, and the tray is transported by the conveyor line. Among them, the battery cells are transported through the tray. To ensure the gap between the battery cells and the tray, the top end of the tray for transporting the battery cells is provided with several slots for placing the battery cells, or convex blocks for placing the battery cells are installed. The tray of the present application preferably installs several convex blocks.

[0009] Preferably, the limiting part includes a third telescopic cylinder and a lifting plate installed at the telescopic end of the third telescopic cylinder. At least two evenly distributed deviation-correcting blocks are provided at the top end of the lifting plate, and a limiting platform for inserting the deviation-correcting blocks is provided at the bottom end of the tray. Among them, a hole is provided in the middle of the limiting platform, and the deviation-correcting blocks are inserted into the holes of the limiting platform. The limiting platform fits against the evenly distributed deviation-correcting blocks to ensure that the lifting plate positions the tray at the required clamping position through the deviation-correcting blocks and the limiting platform, ensuring the accuracy of the tray at the preset position.

[0010] Preferably, a support platform flush with the end of the limiting platform is further installed at the bottom end of the tray, and support columns for supporting the end face of the support platform are installed at the top end of the lifting plate and / or outside the deviation-correcting blocks. Among them, the support columns are used to fit the limiting platform and the support platform, facilitating the tray to remain horizontal during lifting, and at the same time, the deviation-correcting blocks can also limit the tray. [[ID=eleven]]

[0011] Preferably, the end of the deviation-correcting block gradually narrows towards the end where it is inserted. Among them, the shape of the end of the deviation-correcting block can be a cone or a frustum of a cone, which is more convenient to insert into the limiting platform without affecting the insertion process.

[0012] Preferably, the blocking part includes a second telescopic cylinder and a blocking block installed at the telescopic end of the second telescopic cylinder. Among them, by driving the blocking block to extend through the second telescopic cylinder, the tray can be blocked by the blocking block to prevent the tray from moving out of the preset position along the conveying direction.

[0013] Preferably, a bottom edge with a notch is provided at the bottom end of the tray, and the notch can accommodate the end of the blocking block. Among them, the notch facilitates the accommodation of the blocking block.

[0014] Preferably, the telescopic positioning member includes a first telescopic cylinder and a push plate installed at the telescopic end of the first telescopic cylinder. The moving direction of the push plate is perpendicular to the moving direction of the limiting portion. Among them, the tray is subjected to forces in the horizontal and vertical directions, ensuring the accurate position of the tray, avoiding the deviation of the tray at the preset position, and greatly improving the accuracy of the tray at the preset position.

[0015] Preferably, it further includes a bracket. The bracket is located at the preset position and is fixed to the telescopic positioning member and the auxiliary positioning member. Among them, the bracket is used to install the first telescopic cylinder to ensure that the first telescopic cylinder and the tray are at the same height. It is also used to install the third telescopic cylinder and the second telescopic cylinder, facilitating the installation of the telescopic positioning member and the auxiliary positioning member around the preset position.

[0016] As can be seen from the above technical solutions, the present utility model has the following beneficial effects:

[0017] In the present utility model, a limiting platform is arranged at the bottom end of the tray, and a deviation-correcting block is installed on the lifting plate. The deviation-correcting block is inserted into the hole of the limiting platform, and the limiting platform is attached to the uniformly distributed deviation-correcting blocks to ensure that the lifting plate makes the tray in the required clamping position through the deviation-correcting blocks and the limiting platform, ensuring the accuracy of the tray at the preset position. At the same time, the first telescopic cylinder drives the push plate to squeeze the tray, making the tray closely lean against the deviation-correcting blocks, ensuring the accurate position of the tray, improving the accuracy of the battery cell stacking, and greatly improving the quality and performance of the battery module production.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will combine the attached drawings and specific embodiments to elaborate on the present utility model in detail. Before elaborating on the technical solutions of the various embodiments of the present utility model, the nouns and terms involved will be explained. In this specification, components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0024] As Figure 1 and Figure 2 shown, a cell loading and positioning device includes a conveying line body 101 that transfers a transfer member 20 carrying a cell 30 to a preset position, and a telescopic positioning member 40 provided at the preset position. The telescopic positioning member 40 presses and limits the transfer member 20. It further includes an auxiliary positioning member 50 provided below the preset position. The auxiliary positioning member 50 includes a blocking portion 501 and a limiting portion 502 provided at the preset position. The blocking portion 501 blocks the transfer member 20 from moving out of the preset position along the transfer direction. The limiting portion 502 includes a part that can move vertically and is inserted into the bottom end of the transfer member 20. Among them, when loading the cell 30, the cell 30 is placed into the transfer member 20, and the transfer member 20 can limit the side of the cell 30 to prevent the cell 30 from deviating during transfer. The transfer member 20 is placed on the conveying line body 101, and the conveying line body 101 moves the transfer member 20 with the cell 30 to the preset position. The preset position is the area clamped by the fixture when loading the cell 30, and this area can be set by those skilled in the art. Both the blocking portion 501 and the limiting portion 502 are located at the preset position. The blocking portion 501 is located at the end of the preset position along the conveying direction of the transfer member 20, and the blocking portion 501 fits or abuts against one side wall of the transfer member 20 to limit the transfer member 20 at the preset position. The limiting portion 502 moves in the vertical direction so that the limiting portion 502 is inserted into the bottom end of the transfer member 20 to position the transfer member 20 at the preset position. Under the push of the telescopic positioning member 40 on the transfer member 20, the transfer member 20 further fits against the part of the limiting portion 502 inserted into the transfer member 20, separating the transfer member 20 from the conveying line body 101, effectively avoiding the transfer member 20 from shifting due to the conveying line body 101 when the conveying line body 101 moves the transfer member 20, ensuring the stability of cell stacking and the quality of battery production.

[0025] As Figure 1 and Figure 3As shown in the figure, the transfer member 20 includes a tray 202 for carrying the battery cells 30. The tray 202 is transported by the conveying line 101. Among them, a plurality of slots for placing the battery cells 30 are provided at the top end of the tray 202, or bumps for placing the battery cells 30 are installed. The tray 202 of the present application preferably installs a plurality of bumps to ensure that there is a gap between the battery cells 30 and the tray 202, which is helpful for clamping. The tray 202 is placed on the conveying line 101, and the conveying line 101 transports the tray 202 from the feeding port to a preset position. The conveying line 101 supports both ends of the tray 202 to reserve a space for accommodating the auxiliary positioning member 50. The specific selection of the conveying line 101 can be made by those skilled in the art, such as using a belt to support both ends of the tray 202 and transporting the tray 202 to the preset position.

[0026] Such as Figure 2 And Figure 3 As shown in the figure, the limiting part 502 includes a third telescopic cylinder 5022 and a lifting plate 5021 installed at the telescopic end of the third telescopic cylinder 5022. At least two evenly distributed deviation-correcting blocks 5024 are provided at the top end of the lifting plate 5021. A limiting platform 203 for inserting the deviation-correcting blocks 5024 is provided at the bottom end of the tray 202. Among them, the deviation-correcting blocks 5024 can be arranged in various forms on the lifting plate 5021, such as arranged along the edge of the lifting plate 5021, arranged diagonally with respect to the lifting plate 5021, and arranged symmetrically with respect to the lifting plate 5021. The third telescopic cylinder 5022 drives the lifting plate 5021 to move in the vertical direction to drive the deviation-correcting blocks 5024 on the lifting plate 5021 to be inserted into the limiting platform 203 at the bottom end of the tray 202. A hole is provided in the middle of the limiting platform 203, and the deviation-correcting blocks 5024 are inserted into the holes of the limiting platform 203. The limiting platform 203 fits on the evenly distributed deviation-correcting blocks 5024 to ensure that the lifting plate 5021 makes the tray 202 in the required clamping position through the deviation-correcting blocks 5024 and the limiting platform 203, and ensures the accuracy of the tray 202 at the preset position.

[0027] As the first implementation manner of the above support, the deviation-correcting blocks 5024 can pass through the tray 202 or not. If the deviation-correcting blocks 5024 pass through the tray 202, the lifting plate 5021 supports the bottom surface of the limiting platform 203, and the deviation-correcting blocks 5024 will not contact the battery cells 30; if the deviation-correcting blocks 5024 do not pass through the tray 202, the deviation-correcting blocks 5024 can be in interference fit with the tray 202 or the middle of the limiting platform 203 is only a groove, and the tray 202 is supported by the deviation-correcting blocks 5024.

[0028] Such as Figure 3 And Figure 4As shown, as a second embodiment of the support, a support platform 204 flush with the end of the limit platform 203 is also installed at the bottom end of the tray 202, and a support column 5023 for supporting the end face of the support platform 204 is installed at the top of the lifting plate 5021 and / or the outside of the correcting block 5024, wherein the support column 5023 can be installed at the top of the lifting plate 5021, or can be installed on the outside of the correcting block 5024, or can be installed at the top of the lifting plate 5021 and the outside of the correcting block 5024, at least two of the support columns 5023 are in contact with the limit platform 203 and the support platform 204, that is, the support platform 204 and the limit platform 203 can be supported by the support columns 5023.

[0029] like Figure 4 As shown, the correction block 5024 gradually narrows toward its plug-in end, wherein the plug-in end of the correction block 5024 can be of various shapes, such as a cone or a frustum, which makes it convenient to plug the correction block 5024 into the limit platform 203 to ensure accuracy, and also makes it convenient to plug the end of the correction block 5024 into the hole of the limit platform 203.

[0030] like Figures 2 - 4 As shown, the blocking portion 501 includes a second telescopic cylinder 5011 and a block 5012 installed at the telescopic end of the second telescopic cylinder 5011. The bottom end of the tray 202 is provided with a bottom edge 201 with a notch, and the notch can accommodate the end of the block 5012. The second telescopic cylinder 5011 can drive the block 5012 to move upward, and the block 5012 is rotatably connected to the end of the second telescopic cylinder 5011. The block 5012 is composed of a block and a guide wheel. The block is rotatably connected to the telescopic end of the second telescopic cylinder 5011, and there is an elastic force that causes the block and the guide wheel to rotate toward the notch of the block 5012. When the tray 202 reaches the preset position, the tray 202 is blocked by the block 5012 and remains in the preset position. When the lifting plate 5021 rises and passes After the correction block 5024 is plugged into the limit platform 203, during the rising process of the pallet 202, the stop block 5012 is squeezed and turned over by the side of the pallet 202 until the stop block 5012 moves down to the notch of the bottom edge 201. At this time, the pallet 202 continues to rise, so that the pallet 202 and the stop block 5012 are no longer in contact; when the pallet 202 falls onto the conveyor line body 101 after completing the action, the stop block 5012 is against the pallet 202, and then the stop block 5012 falls rapidly under the drive of the second telescopic cylinder 5011, and the notch can make the stop block 5012 and the pallet 202 quickly separate and not contact, avoiding excessive and long contact affecting the descent and reset of the stop block 5012 and the downstream of the pallet 202, and the pallet 202 returns along the original route of the conveyor line body 101.

[0031] like Figure 1 and Figure 4As shown, the telescopic positioning member 40 includes a first telescopic cylinder 401 and a push plate 402 mounted on the telescopic end of the first telescopic cylinder 401. The moving direction of the push plate 402 is perpendicular to the moving direction of the limiting portion 502. Among them, when the first telescopic cylinder 401 extends, it drives the push plate 402 to squeeze the side of the tray 202, so that the tray 202 is subjected to a force in the horizontal and vertical directions, ensuring the accurate position of the tray 202 and preventing the tray 202 from shifting at the preset position, greatly improving the accuracy of the tray 202 at the preset position.

[0032] As Figure 1 , Figure 2 and Figure 4 shown, it further includes a bracket 102. The bracket 102 is located at the preset position and is fixed to the telescopic positioning member 40 and the auxiliary positioning member 50. Among them, the bracket 102 is fixed to the first telescopic cylinder 401 to ensure that the first telescopic cylinder 401 and the tray 202 are at the same height. At the same time, the third telescopic cylinder 5022 and the second telescopic cylinder 5011 are both fixedly installed at the top of the bracket 102 and are used to support the blocking portion 501 and the limiting portion 502. At the same time, the bracket 102 is also fixedly installed with a fourth telescopic cylinder 5025. The fourth telescopic cylinder 5025 has the same function as the third telescopic cylinder 5022 and drives the lifting plate 5021 to move up and down. The fourth telescopic cylinder 5025 and the third telescopic cylinder 5022 are both distributed at the diagonal opposite positions of the lifting plate 5021 for jacking, which can effectively ensure the relative vertical movement and avoid deviation and jamming during the jacking process. The lifting plate 5021 moves up to lift the tray 202. The bracket 102 and the conveying line body 101 together form a support member 10, and the entire support member 10 is used for its supporting and transporting functions.

[0033] Among them, the first telescopic cylinder 401, the second telescopic cylinder 5011, the third telescopic cylinder 5022, and the fourth telescopic cylinder 5025 can be pneumatic, hydraulic or electric, and preferably cylinders are used.

[0034] During use, the tray 202 is transferred to the preset position through the conveying line body 101. The second telescopic cylinder 5011 drives the blocking block 5012 to rise and block the tray 202. Secondly, the third telescopic cylinder 5022 drives the lifting plate 5021 to rise, so that the deviation-correcting block 5024 is inserted into the hole of the limiting table 203, and the support column 5023 supports the support table 204 and the limiting table 203. The first telescopic cylinder 401 drives the push plate 402 to squeeze the side of the tray 202 to fix the position of the tray 202, so as to ensure the accuracy of subsequent clamping of the battery cell 30.

[0035] The above-described embodiments are merely descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
