Description

Technical Field

[0001] This application belongs to the technical field of lithium battery production equipment, and particularly relates to a glue stripping mechanism and a glue pasting device. Background Art

[0002] A battery cell module is formed by stacking multiple battery cells. A spacer (such as a mica sheet) needs to be pasted between two adjacent battery cells, and the spacer can play roles of insulation, fire prevention, and heat insulation. The pasting surface of some spacers is not sticky. Therefore, before pasting the spacer, a glue strip needs to be pasted on the surface of the battery cell first, and then the spacer is pasted on the battery cell through the glue strip.

[0003] In order to achieve automated production, usually, a glue stripping mechanism is first used to peel the glue strip from the release film on the surface of the glue strip, and then a glue pasting mechanism picks up the peeled glue strip and pastes the picked glue strip on the surface of the battery cell. The existing glue stripping mechanism pushes the glue strips to a specially set bearing platform one by one to separate the glue strip from the release film. The glue pasting mechanism then picks up the peeled glue strip from the bearing platform and performs pasting. This method is prone to displacement during the automatic movement of the glue strip to the bearing platform, and it is also impossible to simultaneously peel multiple glue strips, resulting in poor position accuracy of the glue strips picked up by the existing glue pasting mechanism and low glue stripping efficiency. Summary of the Utility Model

[0062] Tape 10: Bottom film 101, top film 102. Detailed implementation manners

[0063] 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 implementation manners.

[0064] To achieve automated production, usually, the adhesive tape is first peeled off from the release film on the surface of the adhesive tape by a tape peeling mechanism, and then the peeled adhesive tape is picked up by a tape pasting mechanism and pasted on the surface of the battery cell. The existing tape peeling mechanism separates the adhesive tape from the release film by pushing the adhesive tapes one by one onto a specially provided loading platform. Then, the tape pasting mechanism picks up the peeled adhesive tape from the loading platform and performs pasting. In this way, the adhesive tape is prone to displacement during the automatic movement to the loading platform, and it is also impossible to peel multiple adhesive tapes simultaneously, resulting in poor position accuracy of the adhesive tapes picked up by the existing tape pasting mechanism and low tape peeling efficiency.

[0065] Therefore, as shown in Figure 1 This application provides a tape peeling mechanism for removing the adhesive tape from the tape 10. The tape 10 includes a bottom film 101, a top film 102, and a plurality of adhesive tapes encapsulated between the bottom film 101 and the top film 102 at intervals. The tape peeling mechanism proposed in the embodiment of this application includes a feeding roller 1, a first film winding roller 2, a tape peeling assembly 3, a second film winding roller 4, and a first handling mechanism 5. The feeding roller 1 is configured to install the tape 10 reel and drive the tape 10 reel to rotate to release the tape 10 to the tape peeling assembly 3; the second film winding roller 4 is arranged below the feeding roller 1 and the first film winding roller 2. The first film winding roller 2 is configured to wind and collect the top film 102 of the tape 10 released by the feeding roller 1. The tape peeling assembly 3 is configured to peel the adhesive tape on the tape 10 after the top film 102 is peeled off from the bottom film 101. The second film winding roller 4 is configured to wind and collect the bottom film 101 after the adhesive tape is peeled off; after the top film 102 is peeled off and before the bottom film 101 is peeled off, the first handling mechanism 5 is configured to adsorb and fix at least one adhesive tape on the tape peeling assembly 3; after the bottom film 101 is peeled off, the first handling mechanism 5 is further configured to transport the adsorbed at least one adhesive tape to the next process.

[0066] It can be seen that the tape peeling mechanism proposed in this application adsorbs and fixes at least one adhesive tape on the peeling assembly by the first handling mechanism after the top film of the tape is peeled off and before the bottom film is peeled off, and then the tape peeling assembly peels the adhesive tape on the tape after the top film is peeled off from the bottom film, avoiding the displacement of the adhesive tape after peeling, improving the accuracy of the tape peeling mechanism for picking up the adhesive tape, and also eliminating the need for a specially provided loading platform for loading the peeled adhesive tape, simplifying the structure and reducing the cost; at the same time, multiple adhesive tapes can be peeled off at one time, and the tape peeling efficiency is high.

[0067] Please refer to Figures 1 to 3As shown, as an implementation manner, the glue stripping assembly 3 includes a first driving member 31 and a glue stripping platform 32. The driving end of the first driving member 31 is connected to the glue stripping platform 32. The glue stripping platform 32 is configured to carry the tape 10 after the top film 102 is peeled off. The first driving member 31 is configured to drive the glue stripping platform 32 to approach or move away from the second film winding roller 4. After the first handling mechanism 5 adsorbs and fixes at least one strip of glue on the glue stripping platform 32, the first driving member 31 drives the glue stripping platform 32 to move closer to the second film winding roller 4, and the second film winding roller 4 winds and collects the bottom film 101 after the glue strip is peeled off, so as to peel off at least one strip of glue adsorbed by the first handling mechanism 5 from the bottom film 101.

[0068] Specifically, the first driving member 31 includes a first motor 310, a transmission lead screw 311 and a lead screw nut 312. The first motor 310 is fixed on the base 313. The transmission lead screw 311 is rotatably installed on the base 313. The rotating shaft of the motor 310 is connected to the transmission lead screw 311. The first motor 310 drives the transmission lead screw 311 to rotate along its own axis. The lead screw nut 312 is sleeved on the transmission lead screw 311 and fixedly connected to the glue stripping platform 32.

[0069] Specifically, the glue stripping platform 32 is slidably installed on the base 313 through a sliding pair composed of a linear guide rail and a slider.

[0070] It can be seen that through the cooperation of the first handling mechanism 5, the first driving member 31, the glue stripping platform 32 and the second film winding roller 4, a glue stripping method is provided in which the glue strip is first adsorbed and fixed, and then while controlling the glue stripping platform 32 to move closer to the second film winding roller 4, the second film winding roller 4 collects the bottom film 101, which is convenient for glue stripping and has high glue stripping efficiency.

[0071] As an implementation manner, the first handling mechanism 5 includes a second driving member 51 and a first adsorption assembly 52. The driving end of the second driving member 51 is connected to the first adsorption assembly 52. The second driving member 51 is configured to drive the first adsorption assembly 52 to move horizontally and vertically. The first adsorption assembly 52 is configured to adsorb at least one strip of glue on the bottom film 101 at a predetermined position on the glue stripping platform 32 or release at least one adsorbed strip of glue.

[0072] Specifically, the second driving member 51 is arranged on the mounting frame 510. The second driving member 51 includes a second motor 511, a driving pulley 512, a driven pulley 513 and a transmission belt 514. The fixed end of the second motor 511 is arranged on the mounting frame 510. The rotating shaft of the second motor 511 is coaxially connected to the first driving wheel 512. The second motor 511 drives the driving pulley 512 to rotate. The driven pulley 513 is rotatably arranged on the mounting frame 510 and is spaced from the driving pulley 512. The transmission belt 514 is installed on the driving pulley 512 and the driven pulley 513. The first adsorption assembly 52 is fixedly connected to the transmission belt 514.

[0073] Specifically, the driving pulley 512 and the transmission pulley 513 are both synchronous pulleys, and the transmission belt 514 is a synchronous belt.

[0074] Specifically, the first adsorption component 52 includes four adsorption parts arranged in parallel, each adsorption part adsorbs one rubber strip, and adsorption holes are arranged on the adsorption surface of the adsorption part or a suction cup is installed, so that the first adsorption component 52 can adsorb four rubber strips at a time.

[0075] It can be seen that through the cooperation of the second driving member 51 and the first adsorption assembly 52, the adsorption and fixation of at least one rubber strip and the automatic transportation of the stripped rubber strip to the next process are achieved, providing a first transport mechanism 5 with high working efficiency and stable and reliable transportation.

[0076] As an implementation manner, a detection member 6 is provided on the stripping platform 32 , and the detection member 6 is configured to detect whether the adhesive strip on the bottom film 101 is transported to a predetermined position.

[0077] It can be seen that by providing the detection member 6, automatic detection of whether the rubber strip on the bottom film 101 is delivered to the predetermined position is achieved, and after the rubber strip is delivered to the predetermined position, the rubber strip peeling mechanism is controlled to peel the rubber strip at the predetermined position.

[0078] As an embodiment, the glue peeling mechanism also includes a tension isolation mechanism 7, which is arranged between the unloading roller 1 and the glue stripping component 3. The tension isolation mechanism 7 is configured to isolate the tension of the tape 10 between the unloading roller 1 and the glue stripping component 3 before the glue strip is peeled off from the base film 101.

[0079] It can be seen that by setting the tension isolation mechanism 7, the tension isolation of the tape 10 between the feed roller 1 and the glue stripping component 3 is achieved when peeling the glue, so as to avoid the glue stripping component 3 pulling the tape 10 released by the feed roller 1 when peeling the glue, thereby ensuring that the glue strip and the base film 101 are peeled off smoothly.

[0080] As an embodiment, the tension isolation mechanism 7 includes a third driving member 71, a clamping member 72 and a clamping platform 73. The driving end of the third driving member 71 is connected to the clamping member 72. The third driving member 71 is configured to drive the clamping member 72 to rise and fall so as to approach or move away from the clamping platform 73. The clamping platform 73 is located below the tape 10. The third driving member 71 drives the clamping member 72 to move close to the clamping platform 73 so as to clamp and fix the tape 10 on the clamping platform 73.

[0081] Specifically, the third driving member 71 is a cylinder, and the piston rod of the cylinder is arranged downward.

[0082] Specifically, the pressing member 72 extends along the first horizontal direction to increase the contact area of ​​the pressing member 72 with the adhesive tape 10 , thereby improving the tension isolation effect of the pressing member 72 .

[0083] It can be seen that through the cooperation of the third driving member 71, the pressing member 72 and the pressing platform 73, the tape 10 is pressed and fixed on the pressing platform 73, providing a method of pressing the tape 10 to achieve tension isolation. The overall structure is simple, easy to implement, and has a good tension isolation effect.

[0084] The glue strip tearing mechanism provided by the embodiment of the present application has the following advantages:

[0085] 1) Before the glue strip is peeled off from the base film 101, the glue strip on the peeling assembly 3 is adsorbed and fixed by the first handling mechanism 5 first, and then the glue strip is peeled off from the base film 101 by the glue strip peeling assembly 3, avoiding the displacement of the glue strip after peeling and improving the accuracy of the glue strip tearing mechanism for picking up the glue strip.

[0086] 2) It can tear multiple glue strips at one time, improving the glue strip tearing efficiency.

[0087] 3) There is no need to specially set up a loading platform for the peeled glue strips, simplifying the structure and reducing the cost;

[0088] 4) It can isolate the tension of the tape 10 between the unwinding roller 1 and the glue strip peeling assembly 3 when the glue strip is peeled off, ensuring the smooth peeling of the glue strip from the base film 101.

[0089] The present application also proposes a glue pasting device. Please refer to Figure 4 and Figure 5 As shown, the glue pasting device provided by the embodiment of the present application includes the above-mentioned glue strip tearing mechanism, the glue strip adjustment mechanism 8 and the second handling mechanism 9.

[0090] The glue strip tearing mechanism is configured to take out at least one glue strip from the tape 10 and transport the taken-out at least one glue strip to the glue strip adjustment mechanism 8;

[0091] The glue strip adjustment mechanism 8 is configured to adjust the position of at least one glue strip;

[0092] The second handling mechanism 9 is configured to pick up at least one glue strip with the adjusted position from the glue strip adjustment mechanism 8 and paste the picked-up at least one glue strip on the battery cell located at the pasting station.

[0093] It can be seen that through the cooperation of the glue strip tearing mechanism, the glue strip adjustment mechanism 8 and the second handling mechanism 9, at least one glue strip is automatically taken out from the tape 10, the position of at least one glue strip is adjusted, and then it is automatically pasted on the battery cell. The glue pasting efficiency is high and the glue pasting accuracy is high; at the same time, the overall structure of the glue strip tearing mechanism is simple and the cost is low.

[0094] Please refer to Figure 4 and Figure 6As shown, as an implementation, the tape adjusting mechanism 8 includes a base 81, a first carrier 82, a second carrier 83, a third carrier 84, a fourth carrier 85, a first distance adjusting component 86, and a rotating component 87. Negative pressure adsorption holes for adsorbing a single tape are provided on each of the first carrier 82, the second carrier 83, the third carrier 84, and the fourth carrier 85; both the first carrier 82 and the fourth carrier 85 extend along the first horizontal direction ( Figure 6 the y direction in Figure 6 ), and are movably mounted on the base 81 along the second horizontal direction ( the x direction in ). The fixed end of the first distance adjusting component 86 is provided on the base 81, and the driving end of the first distance adjusting component 86 is connected to the first carrier 82 and / or the fourth carrier 85. The second horizontal direction is perpendicular to the first horizontal direction; the rotating component 87 is mounted at the middle position of the base 81. The second carrier 83 and the third carrier 84 are connected side by side to the driving end of the rotating component 87 and are located between the first carrier 82 and the fourth carrier 85. The rotating component 87 is used to drive the second carrier 83 and the third carrier 84 to rotate synchronously to the loading state or the unloading state. When the second carrier 83 and the third carrier 84 rotate synchronously to the loading state, they extend along the first horizontal direction. When the second carrier 83 and the third carrier 84 rotate synchronously to the unloading state, they extend along the second horizontal direction.

[0095] Specifically, the tape tearing mechanism takes out four tapes extending along the first horizontal direction from the tape 10 at a time, and places the four tapes extending along the first horizontal direction on the first carrier 82, the fourth carrier 85, and the second carrier 83 and the third carrier 84 in the loading state respectively;

[0096] The first distance adjusting component 86 drives the first carrier 82 and the fourth carrier 85 to move away from each other, so that the distance between the two tapes carried on the first carrier 82 and the fourth carrier 85 reaches the first predetermined distance;

[0097] The rotating component 87 drives the second carrier 83 and the third carrier 84 to rotate synchronously to the unloading state, so that the two tapes carried on the second carrier 83 and the third carrier 84 extend along the second horizontal direction.

[0098] Specifically, the distance between the two outer tapes can be adjusted to match the length dimension of the battery cell, so that the two outer tapes can be attached to the edges of the two short sides of the battery cell surface.

[0099] It can be seen that by setting the rubber strip adjusting mechanism 8, the rubber strip adjusting mechanism 8 can adjust the positions of the four rubber strips. By means of the first distance adjusting component 86 driving the first carrier 82 and the fourth carrier 85 to approach or move away synchronously, the position accuracy of the two symmetric sides of the rubber strip on the surface of the battery cell is ensured, and the rubber strip pasting efficiency is improved.

[0100] As an implementation manner, the first distance adjusting component 86 includes a third motor 861, a first pulley (not shown in the figure), a second pulley 862 and a first transmission belt 863. The first pulley and the second pulley 862 are arranged on the base 81 at intervals along the second horizontal direction. The transmission belt is sleeved on the first pulley and the second pulley 862. The fixed end of the third motor 861 is installed on the base 81, and the driving end of the third motor 861 is connected to the first pulley. The third motor 861 is configured to drive the first pulley to rotate; the first side belt body of the first transmission belt 863 in the first horizontal direction is fixedly connected to the first carrier 82, and the second side belt body of the first transmission belt 863 in the first horizontal direction is fixedly connected to the fourth carrier 85; the third motor 861 drives the first transmission belt 863 to rotate through the first pulley and the second pulley 862, so as to drive the first carrier 82 and the fourth carrier 85 to move in opposite directions.

[0101] It can be seen that a first distance adjusting component 86 with a simple structure is provided, which drives the first transmission belt 863 to rotate through the third motor 861, thereby simultaneously driving the first carrier 82 and the fourth carrier 85 to approach or move away from each other in the second horizontal direction, improving the working efficiency.

[0102] Optionally, as an implementation manner, the rubber strip adjusting mechanism 8 can only adjust the distances between the first carrier 82, the second carrier 83, the third carrier 84, and the fourth carrier 85 without angle adjustment. In addition, the number of carriers can also be set according to actual situations, which will not be elaborated here.

[0103] Please refer to Figure 4 and Figure 7 As shown, as an implementation manner, the second handling mechanism 9 includes a fourth driving member 91, a second adsorption component 92 and a second distance adjusting component (not shown in the figure). The driving end of the fourth driving member 91 is connected to the second adsorption component 92. The fourth driving member 91 is at least configured to drive the second adsorption component 92 to move horizontally and vertically; the second adsorption component 92 includes a substrate 920, a first adsorbent 921, a second adsorbent 922, a third adsorbent 923 and a fourth adsorbent 924. The substrate 920 is installed at the driving end of the fourth driving member 91. The first adsorbent 921 and the fourth adsorbent 924 are fixedly arranged on the substrate 920 at intervals along the second horizontal direction ( Figure 7 the x direction in Figure 7extends in the y direction. The first suction member 921 is used to suck the adhesive tape located on the first carrier 82, and the fourth suction member 924 is used to suck the adhesive tape located on the fourth carrier 85. The second suction member 922 and the third suction member 923 are both slidably mounted on the substrate 920 along the first horizontal direction and both extend along the second horizontal direction. The second suction member 922 is used to suck the adhesive tape located on the second carrier 83, and the third suction member 923 is used to suck the adhesive tape located on the third carrier 84. The second distance adjustment assembly is disposed on the substrate 920 and is configured to drive the second suction member 922 and the third suction member 923 to approach or move away from each other along the first horizontal direction so that the distance between the two adhesive tapes adsorbed on the second suction member 922 and the third suction member 923 reaches the second predetermined distance.

[0104] It can be seen that by setting the second handling mechanism 9, the second handling mechanism 9 can synchronously carry four adhesive tapes, and during the handling process, the distance between the two adhesive tapes extending along the second horizontal direction in the middle is adjusted so that the four adhesive tapes form a rectangular frame shape matching the surface of the battery cell, saving adjustment steps and improving the adhesive tape pasting efficiency.

[0105] Please refer to Figures 3 to 7 As shown in the figure, the specific adhesive tape pasting steps of the above adhesive tape pasting device are as follows:

[0106] The tape roll on the unwinding roller 1 is pulled to the tape stripping assembly 3, and the bottom film of the tape is wound around the second film rewinding roller 4, and the top film of the tape is wound around the first film rewinding roller 2.

[0107] The first film rewinding roller 2 winds and collects the top film 102. At the same time, while the second film rewinding roller 4 winds and collects the bottom film 101, it drives the adhesive tape on the bottom film 101 to move. When the detection member 6 detects that the adhesive tape on the bottom film is conveyed to the predetermined position, the first film rewinding roller 2 and the second film rewinding roller 4 stop rotating, and then the second driving member 51 drives the first suction assembly 52 to adsorb and fix the four adhesive tapes at the predetermined position.

[0108] The tension isolation mechanism 7 isolates the tension of the tape between the unwinding roller 1 and the tape stripping assembly 3.

[0109] The first driving member 31 drives the tape stripping platform 32 to move closer to the second film rewinding roller 4, and cooperates with the first suction assembly 52 to peel the four adsorbed adhesive tapes from the bottom film. At the same time, the second film rewinding roller 4 winds and collects the peeled bottom film 101.

[0110] The second driving member 51 transports the four peeled adhesive tapes to the first carrier 82, the second carrier 83, the third carrier 84 and the fourth carrier 85, and adjusts the positions of the four adhesive tapes.

[0111] The fourth driving member 91 drives the second adsorption assembly 92 to adsorb the rubber strips on the first carrier 82, the second carrier 83, the third carrier 84, and the fourth carrier 85 after the adsorption position is adjusted, and adjusts the positions of the adsorbed rubber strips again so that the four rubber strips are distributed in a rectangular frame;

[0112] The fourth driving member 91 drives the second adsorption assembly 92 to attach the four rubber strips adjusted to a rectangular frame to the corresponding battery cells.

[0113] The rubber strip attaching device provided by the embodiment of the present application has the following advantages:

[0114] 1) It realizes automatically taking out at least one rubber strip from the tape, adjusting the position of at least one rubber strip, and then automatically attaching it to the battery cell. The rubber strip attaching efficiency is high and the attaching accuracy is high; at the same time, the overall structure of the rubber strip tearing mechanism of the rubber strip attaching device is simple and the cost is low;

[0115] 2) Through the cooperation of the rubber strip adjusting mechanism and the second handling mechanism, it realizes adjusting the four rubber strips into a rectangular frame shape matching the surface of the battery cell, saving the adjustment steps and improving the rubber strip attaching efficiency.

[0116] The above embodiments only illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples. Without departing from the spirit and scope of the present application, there are various changes and modifications to the present application, and these changes and modifications all fall within the scope of the present application claimed. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
