Description

Technical Field

[0001] The utility model relates to the field of taping machines, in particular to a double-sided taping mechanism. Background Art

[0002] At present, the taping of battery tabs for lithium batteries is divided into single-sided taping and double-sided taping. Double-sided taping is generally divided into two taping operations, that is, the two sides of the tab are taped separately in sequence. When taping the two sides of the tab, it is easy to have deviations, resulting in low alignment accuracy of the tapes on both sides and prone to defective products. Moreover, the taping equipment for taping in two separate operations has a complex structure, occupies a large space, and takes a long time in the process of taping the tapes, resulting in disadvantages such as low working efficiency, high production cost, and poor taping effect of the tapes. Therefore, there is an urgent need in the field to develop a double-sided taping mechanism that can firmly tape the two sides of the tab that needs double-sided taping, ensure accurate taping of the upper and lower tapes, save taping time, improve taping efficiency, reduce the volume of the taping equipment, and simplify the structure of the taping equipment. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a double-sided taping mechanism.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: The double-sided taping mechanism includes a workbench. A tape unwinding and length-determining pulling-out mechanism is arranged on the workbench. A cutting mechanism for cutting the tape is arranged on one side of the tape unwinding and length-determining pulling-out mechanism. A double-sided taping component for synchronous taping is arranged on one side of the cutting mechanism. The tape unwinding and length-determining pulling-out mechanism unwinds the tape roll and pulls out a tape of a determined length. The cutting mechanism cuts the tape pulled out by the tape unwinding and length-determining pulling-out mechanism. The double-sided taping component sucks, conveys, and synchronously tapes the cut tape.

[0005] Furthermore, the tape unwinding and length-determining pulling-out mechanism includes a tape unwinding and pulling glue vertical plate installed on the workbench. A tape unwinding component is arranged on the tape unwinding and pulling glue vertical plate. A tape fixing component is arranged on one side of the tape unwinding component. A length-determining tape pulling component is arranged on one side of the tape fixing component. The tape unwinding component unwinds the tape roll. The length-determining tape pulling component clamps the front end of the tape and pulls out a tape of a predetermined length. The tape fixing component presses and fixes the tape after pulling out the predetermined length.

[0006] Further, the unwinding component includes an unwinding side plate disposed on one side of the unwinding and glue-pulling vertical plate. At the upper end of the unwinding side plate, a first tape unwinding assembly is provided, and at the lower end of the unwinding side plate, a second tape unwinding assembly is provided. The first tape unwinding assembly includes a tape reel mounted on the unwinding side plate. Below the tape reel, a conveying roller group is provided. On one side of the conveying roller group, a tensioning component is provided. The conveying roller group includes a first conveying roller and a second conveying roller. The tensioning component includes a first tensioning fixed seat and a second tensioning fixed seat mounted on the unwinding side plate. Between the first tensioning fixed seat and the second tensioning fixed seat, two tensioning guide shafts are connected. The two tensioning guide shafts are arranged in balance. A tensioning slide seat is commonly connected to the two tensioning guide shafts. A tensioning roller is provided on the tensioning slide seat. On one end of the two tensioning guide shafts close to the conveying roller group, tensioning springs are respectively provided. The tensioning springs push the tensioning slide seat to drive the tensioning roller to tension the tape. The tape is led out from the tape reel and then bypasses the first conveying roller, the tensioning roller, and the second conveying roller in sequence. The first conveying roller and the second conveying roller convey the tape, and the tensioning roller tensions the tape. The structure of the second tape unwinding assembly is symmetrically arranged with the structure of the first tape unwinding assembly in a mirror image. The working principle of the second tape unwinding assembly is the same as that of the first tape unwinding assembly. The tape includes a first tape and a second tape. The first tape unwinding assembly unwinds and conveys the first tape, and the second tape unwinding assembly unwinds and conveys the second tape.

[0007] By adopting the above technical solution, two rolls of the same or different tapes can be unwound synchronously through the first tape unwinding assembly and the second tape unwinding assembly respectively. When the tape bypasses the first conveying roller, the tensioning roller, and the second conveying roller for conveying, the traction force of the tape conveying will pull the tensioning roller to deflect towards the conveying roller group and squeeze the tensioning spring. By respectively providing a tensioning component on one side of each conveying roller group, the tensioning spring in the tensioning component can use its own rebound effect to push the tensioning slide seat to drive the tensioning roller to deflect away from the conveying roller group, thereby realizing the tensioning of the tape that has been unwound and conveyed through the tensioning roller, ensuring that the tape maintains a certain tension during the conveying process, and further ensuring the accuracy of the pulled-out length of the tape.

[0008] Further, the tape fixing component includes a first linear sliding module. The first linear sliding module is fixed on the unwinding and glue-pulling vertical plate through a module mounting block. The upper end of the first linear sliding module is connected with a first tape pressing component, and the lower end of the first linear sliding module is connected with a second tape pressing component. The first tape pressing component and the second tape pressing component synchronously clamp the first tape and the second tape respectively.

[0009] By adopting the above technical solution, after the first tape in the tape is unwound from the tape reel on one side of the upper end of the unwinding side plate and the second tape in the tape is unwound from the tape reel on one side of the lower end of the unwinding side plate, the first tape pressing component and the second tape pressing component synchronously press or clamp the first tape and the second tape respectively.

[0010] The tape fixing component further includes a second linear sliding module, which is fixed on the unwinding side plate.

A movable pressing block is provided on the side of the fixed pressing block facing the second tape pressing component. The output end of the first driving unit is connected with a pressing block connecting plate, and the pressing block connecting plate is integrally formed with the movable pressing block. The first driving unit drives the movable pressing block to slide on the first linear sliding module through the pressing block connecting plate. The movable pressing block moves closer to or away from the fixed pressing block to clamp or release the tape. The structure of the second tape pressing component is mirror-symmetric to the structure of the first tape pressing component, and the working principle of the second tape pressing component is the same as that of the first tape pressing component. The movable pressing block of the first tape pressing component is connected and mounted with one of the sliders of the first linear sliding module, and the movable pressing block of the second tape pressing component is connected and mounted with the other slider of the first linear sliding module.

[0012] The first tape bearing component includes a bearing moving plate. One end of the bearing moving plate away from the second tape bearing component is connected with a second driving unit. A glue block mounting block is provided at one end of the bearing moving plate close to the second tape bearing component. A non-sticky glue block is provided on the glue block mounting block. The second driving unit drives the bearing moving plate and then drives the non-sticky glue block to move up and down.

The bearing moving plate of the first tape bearing component is connected and mounted with one of the sliders of the second linear sliding module, and the bearing moving plate of the second tape bearing component is connected and mounted with the other slider of the second linear sliding module. The non-sticky glue blocks of the first tape bearing component and the second tape bearing component move closer to each other to avoid the fixed-length tape pulling of the fixed-length tape pulling component.

[0013] By adopting the above technical solution, a first linear sliding module is provided on the unwinding glue pulling vertical plate and a second linear sliding module is provided on the unwinding side plate. The first glue pressing component and the second glue pressing component can clamp and fix the tape through the first linear sliding module. The first tape carrying component and the second tape carrying component can support the tape through the second linear sliding module. The design that the first linear sliding module and the second linear sliding module are on different sides enables the separation of the function of clamping and fixing the tape from the function of supporting the tape. At the same time, it also has the function of avoiding the action of the fixed-length tape pulling component pulling out the tape by a fixed length, making the structural design more delicate and compact, avoiding complex structural design, and enabling the reduction of the manufacturing cost of the equipment while reducing the space volume of the equipment.

When the fifth driving unit in the first cutting component drives the connected cutter to cut the first tape, the fifth driving unit in the second cutting component synchronously drives the connected cutter to cut the second tape.

[0018] By adopting the above technical solution, the fourth driving unit drives the cutting moving plate to reciprocate linearly on the third linear sliding module. The first cutting assembly and the second cutting assembly can move together with the movement of the cutting moving plate, so that the first cutting assembly and the second cutting assembly can synchronously move to the side of the tape respectively under the drive of the fourth driving unit, enabling the first cutting assembly and the second cutting assembly to achieve synchronous positioning before cutting the tape.

[0019] Further, the double-sided taping assembly includes a second lead screw linear module installed on the workbench. The second lead screw linear module is connected to a sixth driving unit.

The first taping assembly and the second taping assembly can move to the unwind and fixed-length pulling mechanism under the drive of the sixth driving unit to respectively suck the film and drive the first taping assembly and the second taping assembly to move to the taping station to synchronously perform double-sided taping on the workpiece. While improving the taping efficiency, it also improves the alignment degree of the film double-sided taping, thereby improving the quality of the workpiece double-sided taping and the yield rate of the workpiece double-sided taping.

[0022] Further, a first limiter and a second limiter are provided on the unwind and pulling glue vertical plate, and the first limiter and the second limiter are mirror-symmetrically arranged.

It can realize the simultaneous conveyance of two same or different tapes (the first tape and the second tape) respectively through the first tape unwinding assembly 61 and the second tape unwinding assembly 62, that is, it can realize the simultaneous conveyance of the double tapes, preparing for the subsequent double-film pasting of the workpiece (tab). Moreover, a tensioning assembly 65 is provided on one side of the conveying roller group 64 in each tape unwinding assembly. When the tensioning spring 656 in each tape unwinding assembly presses the tensioning sliding seat 654, it can drive the tensioning roller 655 to tension the tape that has been unwound and conveyed through the tensioning roller 655. The structural design of the tensioning assembly 65 ensures that the tape maintains a certain tension during the conveying process and ensures the accuracy of the length of the tape pulled out subsequently.

[0059] When the tape is conveyed to the side of the tape fixing member 7 close to the fixed-length tape pulling member 8, since the fixed-length tape pulling moving plate 83 in the fixed-length tape pulling member 8 can make a linear reciprocating displacement along with the first lead screw linear module 81 and under the drive of the third driving unit 82, the first clamping unit 84 and the second clamping unit 85 can displace along with the displacement of the fixed-length tape pulling moving plate 83; when the first clamping unit 84 and the second clamping unit 85 displace to the sides of the corresponding tape fixing member 7 along with the fixed-length tape pulling moving plate 83 and under the drive of the third driving unit 82, they can clamp the tape; after the first clamping unit 84 and the second clamping unit 85 clamp the tape respectively, they move away from the tape fixing member 7 along with the fixed-length tape pulling moving plate 83 and under the drive of the third driving unit 82 to realize the synchronous pulling out of two fixed-length tapes.

[0060] By respectively providing a first tape pressing assembly 73 and a second tape pressing assembly 74 in each tape fixing member 7, the first driving unit 733 in each pressing assembly drives the movable pressing block 734 to slide on the first linear sliding module 71 through the pressing block connecting plate 735. When the first driving unit 733 drives the movable pressing block 734 to move closer to the fixed pressing block 732, it can clamp the tape passing between the fixed pressing block 732 and the movable pressing block 734, which provides accuracy guarantee for the cutting mechanism 3 to cut the tape. On the contrary, when the first driving unit 733 drives the movable pressing block 734 to move away from or in the opposite direction of the fixed pressing block 732, it can loosen the clamping of the tape passing between the fixed pressing block 732 and the movable pressing block 734, enabling the tape to resume the conveying state to facilitate the fixed-length pulling tape member 8 to pull out the next fixed-length tape. The first tape fixing member 7 and the second tape fixing member 7 can synchronously press and fix the double tapes (i.e., the first tape and the second tape) respectively.

[0061] It also connects a first tape bearing assembly 76 and a second tape bearing assembly 77 to the upper and lower ends of the second linear sliding module 75 respectively. The second driving unit 762 in each tape bearing assembly drives the bearing moving plate 761 to move up and down on the second linear sliding module 75, so that the rubber block mounting block 763 can move up and down with the displacement of the bearing moving plate 761. By providing a non-sticky rubber block 764 on each rubber block mounting block 763, the non-sticky rubber block 764 can move with the movement of the rubber block mounting block 763. When the non-sticky rubber blocks 764 of the first tape bearing assembly 76 and the second tape bearing assembly 77 move closer to each other, they can avoid the fixed-length pulling tape operation of the fixed-length pulling tape member 8. On the contrary, when the non-sticky rubber blocks 764 of the first tape bearing assembly 76 and the second tape bearing assembly 77 move away from each other in the opposite direction, they can bear the tape passing through them, playing a role of limiting and supporting for the cutting mechanism 3 to cut the tape, so as to ensure good cutting effect and high cutting efficiency of the cutting mechanism 3 for the tape. In addition, it arranges the first tape pressing assembly 73 and the second tape pressing assembly 74 to move on the first linear sliding module 71, and arranges the first tape bearing assembly 76 and the second tape bearing assembly 77 to move on the second linear sliding module 75, while the first linear sliding module 71 and the second linear sliding module 75 are respectively arranged on two adjacent sides, so that the clamping and fixing operation of the tape and the supporting function for the tape are separated, and it can avoid the pulling movement of the tape, making its overall structure more delicate. It avoids complex structural design, can reduce the space volume of the equipment while reducing the manufacturing cost of the equipment.

[0062] It is provided with a first cutting component 35 and a second cutting component 36 in the cutting mechanism 3 respectively. When the fixed-length tape pulling component 8 pulls out a fixed-length section of tape and the tape fixing component 7 presses the tape tightly, the cutting moving plate 34 moves along the third linear sliding module 32 under the drive of the fourth drive unit 33 to the position where the tape needs to be cut. Then, when the fifth drive unit 35 in the first cutting component 35 and the second cutting component 36 drives the cutter 3531 to move synchronously towards the tape on the non-sticky block 764, the tape can be cut into film pieces. Then, the cutter 353 is reset under the drive of the fifth drive unit 351. It can realize synchronous cutting of double tapes through the cutting mechanism 3, so as to improve the cutting efficiency and the cutting accuracy of double tapes, and avoid the phenomenon that the cutting lengths of double tapes are inconsistent.

[0063] It is provided with a first pasting component 44 and a second pasting component 45 in the double-sided pasting component 4. When the double tapes are cut, the pasting moving frame 43 in the double-sided pasting component 4 can make a linear reciprocating movement through the second screw linear module 41 and under the drive of the sixth drive unit 42, so that the first pasting component 44 and the second pasting component 45 can move with the movement of the pasting moving frame 43. And the suction heads 443 in the first pasting component 44 and the second pasting component 45 can move up and down under the drive of the seventh drive unit 441. When the seventh drive unit 441 cooperates with the sixth drive unit 42 to drive the suction heads 443 in the first pasting component 44 and the second pasting component 45 to move synchronously to the non-sticky block 764, the cut film pieces can be sucked from the non-sticky block 764 and conveyed to the workpiece (tab) that needs to be double-sided pasted with film pieces. When the suction heads 443 in the first pasting component 44 and the second pasting component 45 move synchronously towards the workpiece (tab) under the drive of the seventh drive unit 441, it can realize pasting the double film pieces on the two sides of the workpiece respectively, that is, it can realize synchronous double-sided pasting of film pieces on the workpiece through the double-sided pasting component 4.

[0064] The overall structural design enables synchronous uncoiling of double tapes, synchronous tensioning and conveying of double tapes, synchronous avoidance of the operation of the unwinding and fixed-length pulling mechanism for pulling double tapes, synchronous pulling of double tapes by a predetermined length, synchronous pre-supporting and limiting support for double tapes that have been pulled by a predetermined length (i.e., fixed length) before cutting, synchronous cutting of double tapes into film pieces respectively, synchronous suction of the cut double film pieces, synchronous conveying of the cut double film pieces, and synchronous pasting of the double film pieces onto both sides of the workpiece. It not only has the advantages of high double-tape conveying efficiency, high double-tape fixed-length pulling accuracy, high double-tape cutting efficiency, high double-tape cutting accuracy, good double-tape cutting effect, high workpiece double-sided pasting efficiency, high workpiece double-sided pasting accuracy, and consistent workpiece double-sided pasting effect. It also realizes the processing of different processes on both sides of the workpiece synchronously on one device, so as to simplify the overall structure of the device, reduce the overall volume of the device, reduce the time consumed for double-sided pasting of film pieces on the workpiece, and reduce the overall production cost of the device. It not only effectively solves the problems that the current equipment for double-sided pasting of tab ears requires two separate pasting operations, resulting in easy deviation, low alignment accuracy, and high defective product rate of the film pieces pasted on both sides of the tab ears, but also solves the problems that the pasting equipment for double-sided pasting of tab ears, which requires two separate pasting operations, has a complex structure, occupies a large space, takes a long time for the workpiece to complete double-sided pasting, and has a high production cost.
