DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Combine the following Figure 1 and Figure 2 The utility model describes a glue pulling and cutting mechanism and a battery cell adhesive tape sticking device.

[0029] An embodiment of the utility model provides a tape pulling and cutting mechanism, including a tape unwinding wheel 200, a tape tensioning wheel group, a first tape clamping assembly, a tape pulling assembly and a tape cutting assembly. The tape unwinding wheel 200, the tape tensioning wheel group, the first tape clamping assembly, the tape pulling assembly and the tape cutting assembly can be arranged on a frame 100.

[0030] The tape unwinding wheel 200 is rotatably connected to the frame 100 , and the tape roll can be fixed on the tape unwinding wheel 200 . When the free end of the tape is pulled, the tape unwinding wheel 200 can rotate relative to the frame 100 to unwind the tape.

[0031] The first tape clamping assembly can be arranged on one side of the tape unwinding wheel 200 in the radial direction. When the free end of the tape is pulled out from the tape roll, it can be fixed on the first tape clamping assembly, and the first tape clamping assembly can also release the free end of the tape.

[0032] The tape tensioning wheel assembly includes a plurality of tensioning wheels, which are distributed between the tape unwinding wheel 200 and the first tape clamping assembly. The free end of the tape passes around the plurality of tensioning wheels and reaches the position of the first tape clamping assembly.

[0033] Among them, at least one tensioning wheel is movably connected to the frame 100, and the tensioning wheel can be called a mobile tensioning wheel 310. A first driving mechanism 320 is also provided between the mobile tensioning wheel 310 and the frame 100 to drive the mobile tensioning wheel 310 to move relative to the frame 100. When the tape is tensioned between the first tape clamping assembly and the tape unwinding wheel 200, the first driving mechanism 320 can drive the mobile tensioning wheel 310 to move relative to the frame 100. At this time, since the free end of the tape is fixed on the first tape clamping assembly, the movement of the mobile tensioning wheel 310 makes the path of the free end of the tape to the first tape clamping assembly longer, so the tape unwinding wheel 200 will rotate and release a part of the tape. This process is a pre-stretching process, and the purpose is to pre-stretch the free end of the tape to a certain length under the fixation of the first tape clamping assembly.

[0034] It should be noted that the moving path of the movable tensioning wheel 310 can be a straight line or a curve. For example, it can move up and down in the vertical direction, or it can move diagonally at an angle to the vertical direction. At this time, the first driving mechanism can be a linear driving mechanism such as a cylinder or an electric push rod to drive the movable tensioning wheel 310 to move in the vertical or inclined direction, or it can move along a circular arc trajectory. At this time, the first driving mechanism can be a rotating driving mechanism such as a rotating cylinder or a rotating motor to drive the movable tensioning wheel 310 to swing along the circular arc trajectory.

[0035] The tape pulling assembly is used to pull the free end of the tape to move so that the tape passes over the tape cutting assembly. The tape pulling assembly can be movably connected to the frame 100, and the tape pulling assembly can clamp or release the free end of the tape, and can move toward or away from the first tape clamping assembly.

[0036] After the tape is pre-stretched by the movable tensioning wheel 310 for a certain distance, the tape pulling assembly moves to the position of the first tape clamping assembly and clamps the free end of the tape, and then the first tape clamping assembly releases the free end of the tape. The tape pulling assembly then moves in the opposite direction, pulling the free end of the tape over the tape cutting assembly. Since the tape has been pre-stretched for a certain length, when the tape pulling assembly drives the free end of the tape to move, it is no longer necessary to overcome the stickiness of the tape roll, thereby solving the problem that the stickiness of the tape roll exerts a pulling force on the tape, which makes the free end of the tape easily detach from the tape pulling assembly.

[0037] The tape cutting assembly is slidably arranged on one side of the area between the tape pulling assembly and the first tape clamping assembly. When the tape pulling assembly drives the free end of the tape to pass over the tape cutting assembly, the tape cutting assembly moves in a direction perpendicular to the plane of the tape to cut the tape.

[0038] In some embodiments of the utility model, the movable tension wheel 310 can be movably connected to the frame 100, and the moving path can be in a vertical direction, an inclined downward direction, or a curved downward direction. The adhesive tape passes around the bottom of the movable tension wheel 310, and the first driving mechanism 320 is arranged on the top of the tension wheel. When the first driving mechanism 320 drives the movable tension wheel to move, the movable tension wheel has a vertical downward sub-movement.

[0039] In a specific embodiment, taking the moving path of the movable tension wheel 310 along the vertical direction as an example, the adhesive tape passes under the movable tension wheel 310. The first driving mechanism 320 may be a cylinder, which is disposed on the top of the movable tension wheel 310, and the free end of the cylinder may abut against the top of the movable tension wheel 310, and the cylinder extends downward and retracts upward.

[0040] When the tape needs to be pre-stretched, the first tape clamping assembly clamps the free end of the tape, and the tape is tensioned between the tape unwinding wheel 200 and the first tape clamping assembly. At this time, the cylinder is pushed downward, overcoming the stickiness of the tape roll and pushing the movable tensioning wheel 310 to move downward, and the tape roll on the tape unwinding wheel 200 releases a section of tape, and then the cylinder is retracted upward to complete the pre-stretching action of the tape.

[0041] When the tape pulling assembly clamps the free end of the tape and drives the free end of the tape to move, the tape drives the movable tensioning wheel 310 to move upward back to the original position, and the tape is always kept in a tensioned state under the action of the gravity of the movable tensioning wheel 310.

[0042] Similarly, in another specific embodiment, when the moving path of the movable tensioning wheel 310 is in an inclined downward direction, the tape passes through the bottom of the movable tensioning wheel 310, and the cylinder serving as the first driving mechanism 320 is arranged at the top of the movable tensioning wheel 310, and the free end of the cylinder abuts against the top of the movable tensioning wheel 310, and the extension direction of the cylinder is parallel to the moving trajectory of the movable tensioning wheel 310.

[0043] When the tape needs to be pre-stretched, the first tape clamping assembly clamps the free end of the tape, and the tape is tensioned between the tape unwinding wheel 200 and the first tape clamping assembly. At this time, the cylinder is pushed out obliquely downward, overcoming the stickiness of the tape roll and pushing the movable tensioning wheel 310 to move obliquely downward, and the tape roll on the tape unwinding wheel 200 releases a section of tape, and then the cylinder is retracted to complete the pre-stretching action of the tape.

[0044] When the tape traction assembly clamps the free end of the tape and drives the free end of the tape to move, the tape drives the movable tensioning wheel 310 to move obliquely upward back to the original position, and the tape is always kept in a tensioned state under the action of the component force of the gravity of the movable tensioning wheel 310 in the vertical direction.

[0045] Similarly, in another specific embodiment, the moving path of the mobile tensioning wheel 310 can also be a curve, for example, a circular arc. The motion trajectory extends in the horizontal and downward directions. Specifically, the mobile tensioning wheel 310 is slidably connected to the frame, and the sliding trajectory is a circular arc. The first driving mechanism can be a rotary cylinder, and the driving end of the rotary cylinder can be connected to a swing rod. The end of the swing rod away from the rotary cylinder is located at the top of the mobile tensioning wheel 310. When the rotary cylinder drives the swing rod to rotate downward, the swing rod drives the mobile tensioning wheel 310 to move downward along the circular arc trajectory. The tape roll on the tape unwinding wheel 200 releases a section of tape, and then the rotary cylinder rotates in the opposite direction to drive the swing rod to retract, thereby completing the pre-stretching action of the tape.

[0046] When the tape traction assembly clamps the free end of the tape and drives the free end of the tape to move, the tape drives the movable tensioning wheel 310 to move back to its original position along an arc trajectory. The tape is always kept in a tensioned state under the action of the vertical component of the gravity of the movable tensioning wheel 310.

[0047] In the above embodiments, during the stretching process of the adhesive tape, the movable tensioning wheel 310 can provide tensioning force for the adhesive tape through gravity or the component force of gravity in the vertical direction.

[0048] In other embodiments of the present invention, the movable tensioning wheel 310 is movably connected to the frame 100, and the moving path can still be along the vertical direction, oblique direction or curved direction, but the difference is that the tape is bypassed by the top of the movable tensioning wheel 310, and the first driving mechanism 320 is arranged at the bottom of the movable tensioning wheel 310.

[0049] When the first driving mechanism 320 drives the movable tensioning wheel 310 to pre-stretch the tape, the moving path of the movable tensioning wheel 310 has an upward component movement. When the first driving mechanism 320 cancels the driving force, the movable tensioning wheel 310 will move in the opposite direction along the moving path under the action of gravity or the component force of gravity in the vertical direction, and cannot provide effective tensioning force for the subsequent stretching process of the tape.

[0050] Therefore, no matter what the movement trajectory of the mobile tensioning wheel 310 is, as long as the mobile tensioning wheel 310 can fall freely under the action of gravity or the component of gravity in the vertical direction after the first driving mechanism 320 cancels the driving force, a damping member needs to be provided between the mobile tensioning wheel 310 and the frame to limit the free fall of the mobile tensioning wheel 310, and the damping member can also provide a certain resistance when the tape is stretched to provide sufficient tensioning force for the tape.

[0051] In some embodiments of the present invention, the first tape clamping assembly includes a fixed clamping jaw 410 , a first movable clamping jaw 420 and a second driving mechanism 430 .

[0052] The fixed jaw 410 is fixed on the frame 100 , the first movable jaw 420 is arranged opposite to the fixed jaw 410 , and the first movable jaw 420 is movably connected to the frame 100 , and the second driving mechanism 430 can drive the first movable jaw 420 to move toward or away from the fixed jaw 410 .

[0053] When the free end of the tape is located between the fixed jaw 410 and the first movable jaw 420 and needs to be clamped, the second driving mechanism 430 drives the first movable jaw 420 to move toward the fixed jaw 410 to clamp the free end of the tape between the first movable jaw 420 and the fixed jaw 410.

[0054] When the tape needs to be released, the second driving mechanism 430 drives the first movable clamping jaw 420 to move in a direction away from the fixed clamping jaw 410, so that the first tape clamping assembly releases the free end of the tape.

[0055] It should be noted that the moving path of the first movable clamping jaw 420 may be a straight line, and in this case the second driving mechanism 430 may be a linear driving mechanism such as a cylinder or an electric push rod.

[0056] Alternatively, the moving path of the clamping end of the first movable jaw 420 can be an arc line. In this case, the second driving mechanism 430 can be a rotating driving mechanism such as a rotating cylinder or a rotating motor. Taking the second driving mechanism 430 as a rotating cylinder as an example, the connecting end of the first movable jaw 420 is connected to the rotating end of the rotating cylinder. When the rotating cylinder rotates, it can drive the clamping end of the first movable jaw 420 to swing along a circular arc trajectory to approach or move away from the fixed jaw 410.

[0057] In some embodiments of the present invention, the tape pulling assembly includes a first support frame 510, a third driving mechanism 520 and a second tape clamping assembly.

[0058] The first support frame 510 is movably connected to the frame 100. For example, the tape pulling assembly is arranged on the right side of the first tape clamping assembly, and the first support frame 510 can slide along the left and right directions of the frame 100. The third driving mechanism 520 can also be a cylinder, which extends to the left and retracts to the right. When the cylinder extends, it can drive the first support frame 510 to move to the left, that is, to move in a direction close to the tape pulling assembly. When the cylinder is retracted, it can drive the first support frame 510 to move to the right, that is, to move away from the tape pulling assembly.

[0059] The second tape clamping assembly is disposed on the first support frame 510 and can move along with the first support frame 510 toward or away from the first tape clamping assembly.

[0060] Before stretching the tape, the third driving mechanism 520 drives the first support frame 510 to drive the second tape clamping assembly to move leftward to the position of the first tape clamping assembly, at which position the second tape clamping assembly clamps the free end of the tape, and the first tape clamping assembly releases the free end of the tape. Subsequently, the third driving mechanism 520 drives the first support frame 510 to drive the second tape clamping assembly to move rightward, thereby driving the free end of the tape to move rightward a distance, thereby completing the stretching action of the tape.

[0061] In some embodiments of the present invention, the second tape clamping assembly includes a second movable clamping jaw 531 and a fourth driving mechanism 532 .

[0062] The second movable clamping jaws 531 are arranged in pairs and are movably connected to the first support frame 510. A fourth driving mechanism 532 is arranged between each second movable clamping jaw 531 and the frame 100, and the fourth driving mechanism 532 can drive the clamping ends of the two second movable clamping jaws 531 to move toward or away from each other to clamp or release the free end of the tape.

[0063] Before or during the third driving mechanism 520 drives the first support frame 510 to move toward the first tape clamping assembly, the two fourth driving mechanisms 532 drive the clamping ends of the two second movable clamping jaws 531 to move away from each other. When the third driving mechanism 520 drives the second tape clamping assembly to move to the position of the first tape clamping assembly through the first support frame 510, the free end of the tape is located between the two second movable clamping jaws 531, and the fourth driving mechanism 532 drives the clamping ends of the two second movable clamping jaws 531 to move toward each other, clamping the free end of the tape.

[0064] It should be noted that the two second movable jaws 531 can be distributed up and down, and can be connected to the first support frame 510 in a vertically movable manner. At this time, the fourth drive mechanism 532 can be a linear drive mechanism such as a cylinder or an electric push rod. Taking the fourth drive mechanism 532 as a cylinder as an example, the cylinder body of the cylinder is connected to the first support frame 510, and the free end of the telescopic rod of the cylinder is connected to the corresponding second movable jaw 531. The two fourth drive mechanisms 532 can drive the two second movable jaws 531 to move toward each other or move away from each other.

[0065] Alternatively, one end of the two second movable clamping jaws 531 may be rotatably connected to the first support frame 510, and the fourth driving mechanism 532 may be a rotating driving mechanism such as a rotating cylinder or a rotating motor. Taking the fourth driving mechanism 532 as a rotating cylinder as an example, the rotating cylinder may drive the corresponding second movable clamping jaws 531 to rotate, so as to drive the clamping ends of the two second movable clamping jaws 531 to swing toward or away from each other.

[0066] In some embodiments of the present invention, the tape cutting assembly includes a second support frame 610 , a cutter 620 and a fifth driving mechanism 630 .

[0067] The second support frame 610 is disposed in the area between the first tape clamping assembly and the tape pulling assembly.

[0068] The cutters 620 may include two cutters 620, which are respectively arranged on the left and right sides of the top of the second support frame 610. When the second support frame 610 moves toward the direction close to the tape, the cutters 620 can be driven to cut the tape to obtain a section of tape between the two cutters 620.

[0069] It should be noted that the movement track of the second support frame 610 can be along the vertical direction, and the fifth driving mechanism 630 can be a linear driving mechanism such as a cylinder or an electric push rod. The second support frame 610 can be arranged below the area between the first tape clamping assembly and the tape pulling assembly.

[0070] When the tape needs to be cut, the fifth driving mechanism 630 drives the cutter 620 to move upward and close to the tape through the second support frame, and the cutter 620 cuts the tape when it contacts the tape.

[0071] Alternatively, one end of the second support frame 610 is rotatably connected to the frame 100, and the portion of the second support frame 610 where the cutter is disposed can swing along an arc trajectory. The fifth driving mechanism 630 can be a rotary driving mechanism such as a rotary cylinder or a rotary motor, which is disposed between the frame 100 and the second support frame 610 to drive the second support frame 610 to swing, thereby driving the cutter 620 to move toward or away from the tape, and when the cutter 620 contacts the tape, the tape is cut.

[0072] In some embodiments of the present invention, the cutter 620 may be a serrated knife. If the blade of the cutter 620 is a straight blade, after cutting the tape multiple times, the adhesive of the tape will be coated on the blade, causing the blade to be unable to cut the tape.

[0073] The cutter 620 provided in the embodiment of the present invention is a serrated knife. Since the blades are all pointed, the contact area between the blade and the tape can be reduced, which can effectively prevent the tape from coating the blade.

[0074] In some embodiments of the present invention, the tape cutting assembly further includes a tape support bracket 710 and a sixth driving mechanism 720 .

[0075] The tape support bracket 710 is disposed in the area between the first tape clamping assembly and the tape pulling assembly. The sixth driving mechanism 720 is disposed between the tape support bracket 710 and the frame 100. The width of the tape support bracket 710 along the left-right direction is smaller than the distance between the two cutters 620, or an avoidance hole can be provided on the tape support bracket 710 for the cutters 620 to pass through.

[0076] Before cutting the tape, the sixth driving mechanism 720 can drive the tape support bracket 710 to move to the bottom of the tape to support the bottom of the tape. At this time, the glue suction mechanism moves downward and contacts the top of the tape. Since the tape support bracket 710 is provided at the bottom of the tape, it can provide sufficient support for the glue suction head of the glue suction mechanism, so that it can be reliably connected to the tape, avoiding the problem of the tape hanging in the air and breaking the vacuum.

[0077] After the glue suction mechanism is connected to the adhesive tape, the second support frame 610 drives the cutter 620 to move upward to cut the adhesive tape, and then the glue suction mechanism transfers the cut adhesive tape to the next process.

[0078] It should be noted that the moving path of the tape support bracket 710 can be along the vertical direction, and the sixth driving mechanism 720 can be a linear driving mechanism such as a cylinder or an electric push rod. Taking the cylinder as an example, the cylinder can be pushed upward to drive the tape support bracket 710 to support the bottom of the tape.

[0079] Alternatively, the moving path of the tape support bracket 710 can be an arc line, in which case the sixth driving mechanism 720 can be a rotary driving mechanism such as a rotary cylinder or a rotary motor. Taking the rotary cylinder as an example, the rotary cylinder can drive the tape support bracket 710 to swing to support the bottom of the tape.

[0080] The embodiment of the utility model further provides a battery cell tape sticking device, including the adhesive pulling and cutting mechanism as described above, and thus has the same advantages as described above.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
