Description

Technical Field

[0001] This application relates to the field of lithium battery production technology, and in particular to a push module, a glue preparation device, and processing equipment. Background Technology

[0002] As the new energy vehicle market continues to expand, the demand for power batteries is also increasing, requiring power battery die-cutting equipment to achieve higher production capacity. For die-cutting equipment, when the working strip is nearly depleted, the start of a spare strip needs to be attached to the end of the working strip to continue die-cutting. The speed and quality of the strip connection significantly impact the production speed and quality of the die-cutting equipment.

[0003] During tape splicing, the adhesive preparation device pulls a section of tape (e.g., single-sided tape) from the roll and cuts it to separate it from the roll. Then, the end of the working tape is aligned with the beginning of the spare tape. The adhesive application device then applies one section of tape to the same side of both the working tape's end and the spare tape's beginning. Finally, another section of tape is applied to the opposite side of both ends, thus completing the tape splicing.

[0004] To pull a section of tape from a roll, a short section of tape is needed for pulling. In related technologies, the tape preparation device has difficulty steadily pushing a short section of tape from the roll, resulting in unstable tape preparation and low efficiency. Utility Model Content

[0054] Reference Figure 1 and Figure 2 According to a first aspect embodiment of this application, a push module includes a connector 100 and a push component 300. The connector 100 has a bearing surface 110 for supporting an adhesive tape 200. The direction in which the adhesive tape 200 leaves the bearing surface 110 is defined as a first direction, which is parallel to the bearing surface 110. A second direction is defined as the opposite of the first direction.

[0055] The push component 300 includes a first drive unit 320 and a pusher 310 (see reference). Figure 2 The first drive unit 320 is used to drive the pusher 310 closer to the bearing surface 110, so that the pusher 310 presses the tape 200 supported by the bearing surface 110. The first drive unit 320 is also used to drive the pusher 310 away from the bearing surface 110, so that the pusher 310 moves away from the tape 200 supported by the bearing surface 110. The first drive unit 320 is also used to drive the pusher 310 to move in a first direction, so that the pusher 310 pressing the tape 200 pushes the tape 200 to move in the first direction; the first drive unit 320 is also used to drive the pusher 310 to move in a second direction.

[0056] The push module according to the embodiments of this application has at least the following beneficial effects: after the pusher 310 presses the tape 200, under the action of the first drive unit 320, the pusher 310 continues to push the tape 200 to move along the first direction, so that a small section of tape 200 is stably extended from the bearing surface 110; after the pusher 310 pushes out the tape 200, it first moves away from the tape 200, and then returns along the second direction, thereby facilitating the cyclical pushing out of a small section of tape 200, thus facilitating the traction of the tape 200.

[0057] Specifically, refer to Figure 1 The first direction can be the lower right, and the second direction can be the upper left.

[0058] Specifically, refer to Figure 2 The first driving unit 320 includes a first driving member 321 and a second driving member 322. The first driving member 321 is used to drive the pushing member 310 to move closer to or away from the bearing surface 110, and the second driving member 322 is used to drive the pushing member 310 to move along a first direction or a second direction. The second driving member 322 may be installed at the output end of the first driving member 321, and the pushing member 310 may be installed at the output end of the second driving member 322; or, the first driving member 321 may be installed at the output end of the second driving member 322, and the pushing member 310 may be installed at the output end of the first driving member 321.

[0059] The first driving component 321 can be one of the following: a cylinder, a linear motor, a hydraulic cylinder, an electric cylinder, a motor-driven rack and pinion mechanism, a motor-driven lead screw and nut mechanism, a motor-driven sprocket and chain mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven crank-slider mechanism. The second driving component 322 can be one of the following: a cylinder, a linear motor, a hydraulic cylinder, an electric cylinder, a motor-driven rack and pinion mechanism, a motor-driven lead screw and nut mechanism, a motor-driven sprocket and chain mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven crank-slider mechanism.

[0060] Specifically, refer to Figure 2 To enable the first drive unit 320 to drive the pusher 310, the push assembly 300 also includes a connecting plate 330, and the connecting seat 100 has a through hole 120. One end of the connecting plate 330 is connected to the output end of the first drive unit 320, and the other end of the connecting plate 330 passes through the through hole 120 and is fixedly connected to the pusher 310 (which can be fixed by fasteners). Thus, after the first drive unit 320 is started, it can drive the pusher 310.

[0061] Reference Figure 3 In some embodiments of this application, the pusher 310 is provided with teeth 311, which are used to press the tape 200 supported by the bearing surface 110.

[0062] By providing teeth 311, the contact area between the pusher 310 and the tape 200 can be reduced, thereby reducing the probability that the tape 200 will stick to the pusher 310.

[0063] Specifically, the tape 200 can be a single-sided adhesive. The non-adhesive side of the single-sided adhesive is supported by the bearing surface 110, and the adhesive side of the single-sided adhesive contacts the teeth 311. When the adhesive side of the single-sided adhesive contacts the teeth 311, the contact area is small, making it less prone to adhesion, thus facilitating the cyclical pushing of the single-sided adhesive by the pusher 310.

[0064] Reference Figure 3 In some embodiments of this application, the push module further includes a cutting component 400, which includes a second drive unit 410 and a cutter 420. The cutter 420 is used to cut the tape 200. The second drive unit 410 is used to drive the cutter 420 closer to the bearing surface 110 to cut the tape 200. The second drive unit 410 is also used to drive the cutter 420 away from the bearing surface 110.

[0065] By setting the cutting component 400, the cutter 420 can be used to quickly cut the tape 200, which is beneficial to completing the tape 200 preparation process.

[0066] Specifically, the cutter 420 can be set on the right side of the bearing surface 110. When the cutter 420 moves downward toward the bearing surface 110, the bearing surface 110 supports the tape 200. The bearing surface 110 and the cutter 420 cooperate to complete the cutting of the tape 200.

[0067] Specifically, the second drive unit 410 is mounted on the connecting base 100. The second drive unit 410 can be one of the following: a cylinder, a linear motor, a hydraulic cylinder, an electric cylinder, a motor-driven gear and rack mechanism, a motor-driven lead screw and nut mechanism, a motor-driven sprocket and chain mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven crank and slider mechanism. Preferably, the second drive unit 410 is a cylinder.

[0068] Reference Figure 3 and Figure 4 In some embodiments of this application, the two ends of the tape 200 after being cut by the cutter 420 are both first ends 210. The pushing module also includes an air blowing component 500, which has an air blowing hole 520. One end of the air blowing hole 520 is used to connect to a positive pressure air source, and the other end of the air blowing hole 520 is used to blow air towards at least one first end 210, so that the blown first end 210 is disengaged from the cutter 420.

[0069] By blowing air onto at least one first end 210 through the air blowing component 500, the probability of the first end 210 adhering to the cutter 420 can be effectively reduced, resulting in a lower cutting failure rate for the cutter 420 and stable operation of the push module.

[0070] It should be noted that after the tape 200 is cut by the cutter 420, two first ends 210 are generated. The air blowing hole 520 can blow air towards either first end 210 or towards both first ends 210 simultaneously. Preferably, refer to Figure 3 The air blowing hole 520 blows air towards the first end 210 on the left side, while the first end 210 on the right side will be sucked by other adsorption mechanisms (such as vacuum adsorption plates) and will not easily stick to the cutter 420. Therefore, there is no need to blow air towards the first end 210 on the right side.

[0071] Specifically, the positive pressure air source can be provided by a blower or by using compressed air.

[0072] Reference Figure 3 and Figure 4 In the improved embodiment described above, the direction of the cutter 420 near the bearing surface 110 is set as the third direction, and the angle between the fourth direction and the third direction is set to be less than 90 degrees; the other end of the air hole 520 is used to blow air along the fourth direction toward at least one first end 210 so that the blown first end 210 is disengaged from the cutter 420.

[0073] By blowing air into at least one first end 210 in the fourth direction from the other end of the air hole 520, the first end 210 can be blown more forcefully, causing the first end 210 to quickly leave the cutter 420, and the separation effect of the first end 210 from the cutter 420 is better.

[0074] Specifically, the angle between the fourth direction and the third direction can be 10 degrees, 20 degrees, 30 degrees, 45 degrees, 60 degrees or other angles.

[0075] Reference Figure 2 In the improved embodiment described above, the air blowing holes 520 are provided in two or more ways and are arranged along the width direction of the tape 200.

[0076] By arranging two or more air holes 520 along the width of the tape 200, various parts of the first end 210 can be blown simultaneously, resulting in a better separation effect between the first end 210 and the cutter 420.

[0077] Specifically, refer to Figure 4 To ensure that each air-blowing hole 520 can be connected to the positive pressure air source, the air-blowing component 500 is also provided with a connecting hole 510. The connecting hole 510 is connected to the positive pressure air source and also to each air-blowing hole 520. Thus, after the positive pressure air source enters into the connecting hole 510, it can be distributed into each air-blowing hole 520, thereby causing the air-blowing holes 520 to blow air towards the first end 210.

[0078] Specifically, the number of air holes 520 can be two, three, four, or other numbers.

[0079] Reference Figure 1 In some embodiments of this application, the space area into which the tape 200 enters after leaving the bearing surface 110 is defined as the first region 610. The push module also includes a first sensor 600, which is used to detect whether the tape 200 exists in the first region 610.

[0080] By setting the first sensor 600, it is easier to determine in a timely manner whether there is tape 200 in the first area 610. When there is no tape 200 in the first area 610, the push module can push out a section of tape 200 in a timely manner, thereby improving the pushing efficiency of tape 200.

[0081] Specifically, the first sensor 600 can be a photoelectric sensor, a capacitive proximity sensor, an inductive proximity sensor, a fiber optic sensor, a vision sensor, or other sensors.

[0082] The working process of the push module of this application will be described in conjunction with the above embodiments.

[0083] Step 1: The first sensor 600 detects that the tape 200 is not present in the first area 610 and sends a signal to the controller.

[0084] The second step is that the controller sends a control signal to the first drive member 321, which drives the push member 310 to approach the bearing surface 110, thereby causing the teeth 311 to press the tape 200 supported by the bearing surface 110.

[0085] Third step: The controller sends a control signal to the second drive unit 322, and the second drive unit 322 drives the pusher 310 to move in the first direction, so that the first end 210 of the tape 200 enters the first region 610.

[0086] Step 4: Tape 200 is pulled by module 740 (refer to...) Figure 5 (and participate in the following text) leads to a section.

[0087] Fifth step: The controller sends a control signal to the second drive unit 410, which drives the cutter 420 to approach the bearing surface 110 to cut the tape 200. After that, the second drive unit 410 drives the cutter 420 away from the bearing surface 110. At the same time, the air blowing component 500 blows air toward the first end 210 to prevent the first end 210 from sticking to the cutter 420.

[0088] Step 6: The adhesive applicator 830 removes the cut tape 200 (refer to...). Figure 5 (and participate below).

[0089] Step 7: Repeat the above steps to achieve the cyclical pushing of tape 200.

[0090] Reference Figure 1 and Figure 5 According to a second aspect embodiment of this application, the adhesive preparation apparatus includes a pushing module, an unwinding roller 710, and a traction module 740. The unwinding roller 710 is used to insert a roll 720, which includes adhesive tape 200. The unwinding roller 710 is also used to unwind the adhesive tape 200. The traction module 740 is used to pull the adhesive tape 200 from the bearing surface 110.

[0091] The adhesive preparation device according to the embodiments of this application has at least the following beneficial effects: by using the above-mentioned pushing module, it is beneficial for the adhesive preparation device to stably pull out the adhesive tape 200, and the adhesive preparation efficiency is higher.

[0092] Specifically, the traction module 740 includes grippers and a third drive unit. The grippers are used to grip the first end 210, and the third drive unit is used to drive the grippers closer to or further away from the bearing surface 110. When the third drive unit drives the grippers that have gripped the first end 210 away from the bearing surface 110, one end of the tape 200 can be pulled out.

[0093] In another embodiment, the gripper can be replaced by a roller. After the roller winds a portion of the first end 210, the third drive unit drives the roller that has wound the first end 210 away from the bearing surface 110, thereby pulling out one end of the tape 200.

[0094] It should be noted that the traction module 740 can use existing technology, and its structure will not be described in detail here.

[0095] Reference Figure 1 In the improved embodiment described above, the glue preparation device further includes a second sensor 730, which is used to detect the diameter of the roll 720 inserted by the unwinding roller 710.

[0096] By setting a second sensor 730, it is possible to detect in a timely manner whether the material roll 720 is used up, which is conducive to timely replacement of the material roll 720, enabling the glue preparation device to work continuously and thus improving the glue preparation efficiency.

[0097] Specifically, the second sensor 730 may be an ultrasonic sensor, a laser displacement sensor, an encoder, a photoelectric sensor, a capacitive proximity sensor, or other sensors.

[0098] The processing apparatus according to a third aspect embodiment of this application includes a glue preparation device, a processing device 810, and a glue application device 830. The glue application device 830 is used to apply the adhesive tape 200 pulled out by the traction module 740 to two separate material strips 820. The processing device 810 is used to process the material strips 820.

[0099] The processing equipment according to the embodiments of this application has at least the following beneficial effects: by using the above-mentioned glue preparation device, it is beneficial for the processing equipment to continuously complete the processing of the material strip 820, and the processing efficiency is higher.

[0100] Specifically, the adhesive applicator 830 includes a fourth drive unit and a suction cup. The fourth drive unit drives the suction cup to move in three-dimensional space, so that the suction cup can adsorb the cut adhesive tape 200 and attach the cut adhesive tape 200 to both sides of the material strip 820, thus completing the connection of the two material strips 820.

[0101] It should be noted that since the adhesive applicator 830 can use existing technology, its structure will not be described in detail here.

[0102] Specifically, the processing device 810 can be a die-cutting device to cut tabs into the strip 820. Alternatively, the processing device 810 can be a cell winding device to wind out the cell.

[0103] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
