Description

Technical Field

[0001] The invention relates to the technical field of lithium battery production, and in particular to an edge folding tape device for lithium batteries. Background Art

[0002] Apply tape to the folded edge of the lithium battery. The lithium battery taping process mainly includes five processes: placing the battery on the positioning block - peeling off the die-cut tape - sticking the die-cut tape to the edge of the battery - aligning the die-cut tape - turning over the folding tape, so as to achieve taping the folded edge of the battery. In the process of taping, due to the high viscosity of the tape, it is difficult to peel the tape off the die-cut backing paper, and the manual operation is inconvenient, resulting in low production efficiency and high labor costs. However, in the process of taping, it is easy for the tape to be loosely bonded, so that the tape is easy to loosen on the battery, thereby affecting the subsequent tape protection of the battery folding position, and the battery folding position is prone to accumulate impurities, making it difficult for the tape to adhere to the folding position, thereby reducing the efficiency of the tape adhesion, and it is easy to have deviations when adhering the tape, resulting in the tape not being easy to adhere to the folding position, thereby reducing the accuracy of the tape adhesion, and it is not easy to control the tape sticking according to the position of the battery folding edge, resulting in the need to adjust the battery position after the tape is pasted.

[0003] In summary, in the process of sticking tape, it is easy for the tape to be bonded in a loose position, causing the tape to loosen on the battery easily. Deviations are easy to occur when sticking the tape, causing the tape to be difficult to stick to the folded edge position, thereby reducing the accuracy of tape adhesion, making manual operation inconvenient, and resulting in low production efficiency. Summary of the invention

[0025] The present invention provides a folding tape device for lithium batteries, which has the following beneficial effects:

[0026] The folding edge adhesive tape device for lithium batteries is provided with a displacer, a moving plate, and a protective shell. When the displacer moves on the protective shell, the moving plate is driven to move horizontally, so that the position of the adhesive tape can be adjusted when the displacer drives the moving plate to move, and the accuracy of the adhesive tape can be ensured when the displacer drives the moving plate to move. The moving plate is driven by the displacer to move along the guide rail, so that the sticking of the adhesive tape is not affected by the jamming of the moving plate when the moving plate moves. The blowing component moves with the moving plate on the sticking component, so that the blowing component can blow the adhesive tape before and after the lithium battery is stuck.

[0027] The folded edge adhesive tape device for lithium batteries moves with the moving plate through the vertical plate, ensuring that the adhesive tape moves to the clamping position through the vertical plate, preventing the adhesive tape from tilting during the pasting process, resulting in the adhesive tape not fully contacting the lithium battery. The pressure plate first contacts the adhesive tape on the vertical plate, so that the pressure plate supports the unclamped adhesive tape, which is convenient for adjusting the length of the beginning of the adhesive tape exceeding the pressure plate when placing the adhesive tape, and can fix adhesive tapes of different volumes, thereby ensuring the stability of the adhesive tape when clamping.

[0028] The folding tape device for lithium batteries is lowered by the extrusion plate being pushed by the extension of the clamping cylinder, thereby avoiding displacement of the tape when it moves toward the lithium battery, resulting in loose adhesion of the tape. The lifting and lowering of the extrusion plate is used to adjust the clamping force of the tape. The limiting block connects the extrusion plate and the pressure plate, so that the limiting block and the clamping cylinder cooperate with each other to limit the moving distance of the extrusion plate, which is convenient for the limiting block to process the extrusion plate and the pressure plate, ensuring that the extrusion plate and the pressure plate remain in a horizontal state.

[0029] The folding tape device for lithium batteries supports the extrusion column on the vertical plate through an adjustment plate, so that the adjustment plate can be rotated under the drive of the adjustment cylinder, so that the angle of the adjustment plate can be adjusted by the extension and contraction of the adjustment cylinder. The extrusion column can adjust the strength of the contact tape and the lithium battery as the adjustment plate rotates, so that the extrusion column rotates to adjust the area of ​​the extruded tape, thereby avoiding wear of the extruded tape on the same side of the extrusion column, and the extrusion column can support the adjustment plate.

[0030] The folding tape device for lithium batteries connects two adjustment plates through a support plate, so that the support plate supports the adjustment plate, ensuring that the two adjustment plates rotate on the vertical plate at the same time, avoiding that the adjustment plate drives the extrusion column to rotate and tilts, resulting in insufficient extrusion of the tape. The cutting blade approaches the tape under the drive of the extension of the cutting cylinder, so that the cutting blade cuts the tape after the tape is pasted when it contacts the tape, ensuring that the tape is cut after being pasted on the battery, avoiding uneven cutting position of the tape.

[0031] The folded edge adhesive tape device for lithium batteries is installed on a movable plate via a fixing seat, so that a placing cylinder can be installed horizontally on the fixing seat, so that the adhesive tape can be placed on the placing cylinder, ensuring that the adhesive tape is pulled after being pasted and rotated on the placing cylinder, and the contact block moves with the pushing ring so as to enter the interior of the blocking disk, so that the contact block is not likely to affect the contact between the blocking disk and the adhesive tape, thereby increasing the contact area of ​​the adhesive tape by cooperating with the contact block and the pushing ring.

[0032] The folded edge adhesive tape device for lithium batteries drives a blocking disk to move on a placement cylinder through a plug-in column, so that the blocking disk blocks the adhesive tape on the placement cylinder to prevent the adhesive tape from falling when rotating on the placement cylinder. The push ring is pushed to drive the contact block close to the adhesive tape, so that the contact block cooperates with the fixing seat to limit the activity space of the adhesive tape to prevent the adhesive tape from moving around on the placement cylinder. The push ring moves along the blocking disk when moving, so as to prevent the push ring from tilting when moving on the blocking disk to affect the uniformity of the position of the extruded adhesive tape.

[0033] The folded edge adhesive tape device for lithium batteries fixes the mounting tube on the vertical plate through the mounting plate and the connecting plate to ensure that the mounting tube is installed horizontally, thereby increasing the bearing capacity of the vertical plate itself; the inner support plate can support the mounting tube to facilitate maintaining the bearing capacity of the mounting tube itself, so that the inner support plate and the air supply fan reinforce the mounting tube at different positions, thereby ensuring the integrity of the mounting tube itself, and allowing the wind to blow to different positions along the inner support plate inside the mounting tube.

[0034] The folded edge adhesive tape device for lithium batteries generates wind force by operating a blower fan inside the installation tube, so that the wind force discharged from the installation tube is blown toward the battery, thereby utilizing the wind force to clean the lithium battery, thereby preventing impurities from adhering to the folded edge of the lithium battery and affecting the sticking of the adhesive tape. The purification box has activated carbon, so that when the purification box contacts the wind force inside the installation tube, the wind force drives the activated carbon inside the purification box to move, so that the purification box is convenient for purification when it contacts the wind force.

[0035] The folded edge adhesive tape device for lithium batteries supports the purification box through a fixing frame on the installation tube via a docking plate, so as to maintain the stability of the installation position of the purification box and enable the fixing frame to circulate wind force. The tray is installed on the end of the installation tube away from the supply fan, and the edge position of the installation tube is fixed by the tray and the supply fan to prevent the end of the installation tube away from the connecting plate from being damaged by collision. The arc plate rotates on the tray under the influence of wind force, so as to avoid the arc plate from being stuck when rotating. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0050] Example 1, please refer to Figure 1-Figure 12 The present invention provides a technical solution: a folding edge adhesive tape device for lithium batteries, comprising a bracket 1, a guide rail 3 is fixedly connected to the top of the inner cavity of the bracket 1, the device is moved as a whole to a position close to the battery through the bracket 1, so that it is convenient to move between two brackets 1 during work, and the installation of the bracket 1 supports the guide rail 3 and the protective shell 2, so that the guide rail 3 is horizontally installed on the bracket 1, so that the guide rail 3 guides the movement of the displacer 4, and the distance between the two brackets 1 is limited by the guide rail 3, and also includes:

[0051] The protective shell 2 is fixedly connected to the top of the inner cavity of the bracket 1. The inner surface of the protective shell 2 is slidably connected with a displacer 4. When the displacer 4 moves on the protective shell 2, the movable plate 5 is driven to move in the horizontal direction, so that the position of the movable plate 5 is adjusted by the movement of the displacer 4, so that the position of the tape can be adjusted when the displacer 4 drives the movable plate 5 to move. When the displacer 4 moves, it is restricted by the protective shell 2, so that the displacer 4 is not easy to deviate during the movement process, ensuring the accuracy of the tape sticking when the displacer 4 drives the movable plate 5 to move, so that the movement of the displacer 4 can be adjusted according to the position of the lithium battery. The displacer 4 is close to the guide rail. The position of 3 is fixedly connected with a moving plate 5, and the moving plate 5 is driven by the displacer 4 to move along the guide rail 3, so that the guide rail 3 and the protective shell 2 cooperate to limit the moving plate 5, ensuring that the moving plate 5 moves smoothly in the horizontal direction on the guide rail 3, preventing the moving plate 5 from being stuck when moving and affecting the sticking of the tape, and the moving plate 5 can drive the placement component 7 and the sticking component 6 to move, which is convenient for reducing the exposure of the tape due to sticking, and preventing the tape from being exposed for too long and adhering to dust and affecting the sticking. When moving, the moving plate 5 can cover the placement component 7 and the sticking component 6, so that the moving plate 5 can play a protective effect when moving on the guide rail 3;

[0052] The pasting component 6 is fixedly connected to the bottom of the movable plate 5. The pasting component 6 is used to clamp the tape and cut the tape after pasting. The inner surface of the pasting component 6 is fixedly connected to the blowing component 8. The blowing component 8 moves with the movable plate 5 on the pasting component 6, so that the blowing component 8 can blow the lithium battery tape before and after pasting, so as to use the wind force blown by the blowing component 8 to clean the lithium battery, prevent dust from accumulating around the folded edge of the lithium battery to affect the pasting of the tape, and thus ensure the stability of the tape pasted on the lithium battery;

[0053] A placing component 7, which is fixedly connected to the bottom of the moving plate 5, and is used to place the tape. Two placing components 7 are arranged on the moving plate 5, and the two placing components 7 correspond to the tape clamping positions on the pasting component 6, so that after the tape is placed on the placing component 7, the placing component cooperates with the pasting component 6 to paste the tape twice on the folding position of the lithium battery, which is convenient for using tapes at different positions according to the folding position of the battery, so that the tape can be continuously pasted on the folding position of the battery when the device is working, ensuring the efficiency of tape pasting;

[0054] The pasting component 6 includes a vertical plate 61, which is fixedly connected to the bottom of the movable plate 5. The vertical plate 61 is provided with a groove corresponding to the placement cylinder 72. The vertical plate 61 moves with the movable plate 5, so that the vertical plate 61 can separate the clamping position of the placement component 7 and the tape, and the vertical plate 61 has a groove for installing the blowing component 8 and moving the tape, so that the groove of the vertical plate 61 can guide the movement of the tape, ensuring that the tape moves to the clamping position through the vertical plate 61, preventing the tape from tilting during the pasting process, resulting in the tape not fully contacting the lithium battery. The vertical plate 61 separates the placement component 7 from the clamping cylinder 62, ensuring that the tape is convenient to take and put on the placement component 7, and the side of the vertical plate 61 away from the placement component 7 is rotatably connected with an adjustment plate 64;

[0055] The clamping cylinder 62 is fixedly connected to the top of the inner cavity of the vertical plate 61, and the bottom end of the clamping cylinder 62 is fixedly connected to a squeezing plate 63. The squeezing plate 63 is pushed down by the extension of the clamping cylinder 62, so that the squeezing plate 63 descends to squeeze the edge of the tape, and the squeezing plate 63 corresponds to the pressure plate 66, so that the squeezing plate 63 and the pressure plate 66 clamp the tape when they contact the tape, avoiding displacement of the tape when it moves toward the direction close to the lithium battery, resulting in loose adhesive tape. The squeezing plate 63 rises with the contraction of the clamping cylinder 62, so that the gap between the squeezing plate 63 and the pressure plate 66 is increased, thereby loosening the clamping of the tape, making it easier to pull the tape when it is pasted, and the lifting and lowering of the squeezing plate 63 is used to adjust the clamping force of the tape, so as to prevent the clamping force from being too large or too small when the tape is clamped, which affects the adhesive tape. The position of the clamping cylinder 62 is fixedly connected with a limiting block 65, and the extrusion plate 63 and the pressure plate 66 are connected through the limiting block 65, so that the limiting block 65 and the clamping cylinder 62 cooperate with each other to limit the moving distance of the extrusion plate 63, so that the limiting block 65 can process the extrusion plate 63 and the pressure plate 66 to ensure that the extrusion plate 63 and the pressure plate 66 remain in a horizontal state, and the limiting block 65 has a spring, so that the spring can play a boosting effect when the extrusion plate 63 rises, and the bottom of the inner cavity of the limiting block 65 is fixedly connected with the pressure plate 66, and the pressure plate 66 first contacts the tape on the vertical plate 61, so that the pressure plate 66 supports the unclamped tape, so that when the tape is placed, the length of the beginning of the tape exceeding the pressure plate 66 can be adjusted, and the pressure plate 66 and the extrusion plate 63 can fully contact the tape when clamping the tape, and can fix tapes of different volumes, thereby ensuring the stability of the tape when clamping.

[0056] The outer surface of the pressure plate 66 is fixedly connected to the vertical plate 61 , and the outer surface of the extrusion plate 63 is slidably connected to the vertical plate 61 .

[0057] The bottom of the displacer 4 extends to the outside of the protective shell 2 , and the top of the moving plate 5 is slidably connected to the guide rail 3 .

[0058] The two ends of the blowing assembly 8 penetrate the vertical plate 61 and extend to the outside of the vertical plate 61 , and the top of the vertical plate 61 penetrates the moving plate 5 and extends to the inside of the moving plate 5 .

[0059] Among them, the inner surface of the adjustment plate 64 is rotatably connected with an extrusion column 641, and the extrusion column 641 can adjust the force of contacting the tape and the lithium battery with the rotation of the adjustment plate 64, so that the extrusion column 641 rotates along the pulled tape with the movement of the displacer 4 when extruding the tape, so that the extrusion column 641 rotates to adjust the extruded tape area, avoiding the wear of the extrusion column 641 on the same side of the extrusion tape. The extrusion column 641 can support the adjustment plate 64, so that the two adjustment plates 64 move under the drive of the adjustment cylinder 643, and the support plate 645 connects the two adjustment plates 64, so that the support plate 645 supports the adjustment plate 64, so that the adjustment cylinder 643 drives the adjustment plate 64 to move through the support plate 645. The adjusting plates 64 are moved to ensure that the two adjusting plates 64 rotate on the vertical plate 61 at the same time, so as to avoid the adjustment plate 64 driving the extrusion column 641 to rotate and cause insufficient extrusion of the adhesive tape. The position of the adjusting plate 64 close to the extrusion column 641 extends to the outside of the vertical plate 61, and the extrusion column 641 is supported on the vertical plate 61 by the adjustment plate 64, so that the adjusting plate 64 is driven by the adjustment cylinder 643 to rotate, so that the adjustment cylinder 643 can adjust the angle of the adjusting plate 64, and the extrusion force of the extrusion column 641 can be controlled by the rotation of the adjustment plate 64. When the adjustment plate 64 drives the extrusion column 641 to rotate, the adhesive tape can be squeezed, so that the extrusion column 641 increases the stability of the pasting position, and prevents the adhesive tape from falling due to the tension after pasting.

[0060] The adjusting cylinder 643 is rotatably connected to the side of the vertical plate 61 close to the adjusting plate 64. The bottom end of the adjusting cylinder 643 is fixedly connected to the supporting plate 645. The inner surface of the supporting plate 645 is fixedly connected to the cutting cylinder 644. The end of the cutting cylinder 644 close to the vertical plate 61 is fixedly connected to the cutting blade 642. The cutting blade 642 is driven by the extension of the cutting cylinder 644 to approach the tape, so that the cutting blade 642 cuts the tape after pasting when it contacts the tape, ensuring that the tape is adhered to the battery. After sticking, it is cut off. After the tape is cut, the cutting blade 642 is driven away from the tape by the contraction of the cutting cylinder 644, so that the extension and contraction of the cutting cylinder 644 adjusts the position of the cutting blade 642 to ensure the force of the cutting blade 642 on the tape to prevent the tape from not being cut. When the cutting blade 642 is cutting, the squeezing column 641 still squeezes the tape, so that the squeezing column 641 can fix the tape, which is convenient for maintaining the integrity of the tape at the squeezing position of the squeezing column 641 to avoid uneven cutting position of the tape.

[0061] Among them, the side of the adjustment plate 64 away from the vertical plate 61 is fixedly connected to the support plate 645 , and both ends of the cutting cylinder 644 penetrate the support plate 645 and extend to the outside of the support plate 645 .

[0062] The placement assembly 7 includes a fixing seat 71, which is fixedly connected to the bottom of the movable plate 5 and is installed on the movable plate 5 through the fixing seat 71, so that the fixing seat 71 supports the placement tube 72, which is convenient for the placement tube 72 to be installed horizontally on the fixing seat 71, so that the tape is placed on the placement tube 72, so that the tape corresponds to the concave position of the vertical plate 61 after being placed on the placement tube 72, ensuring that the tape is pulled after being pasted and rotated on the placement tube 72, and two fixing seats 71 are arranged on the movable plate 5, so that the fixing seat 71 and the placement tube 72 cooperate to place the tape at different positions, and the outer surface of the fixing seat 71 is fixedly connected with the placement tube 72;

[0063] The plug-in column 75 is slidably connected to the inner surface of the placement tube 72, and the plug-in column 75 drives the blocking plate 73 to move on the placement tube 72, so that the blocking plate 73 blocks the tape on the placement tube 72 to prevent the tape from falling when rotating on the placement tube 72. The plug-in column 75 is inserted into the placement tube 72 to fix the blocking plate 73. The distance that the plug-in column 75 moves inside the placement tube 72 is used to drive the blocking plate 73 to move and adjust the space for placing the tape, so as to adjust the space according to different tapes.

[0069] Example 2, please refer to Figure 1-Figure 12On the basis of Example 1, the present invention provides a technical solution: a method for using a folding tape device for lithium batteries, step 1: move the bracket 1 to the position where the battery is placed, the plug-in column 75 is separated from the placement tube 72 by tension, and two tapes are placed on the two placement tubes 72 respectively, and then the plug-in column 75 is placed inside the placement tube 72 again, so that the blocking disk 73 driven by the plug-in column 75 cooperates with the fixing seat 71 to limit the placed tape, and apply pressure to the push ring 74, so that the push ring 74 drives the contact block 76 on the blocking disk 73 to move to contact the tape, and the placement of the tape is positioned by using the contact between the contact block 76 and the tape;

[0070] Step 2: After the battery is placed, the beginning of the tape is passed through the groove corresponding to the vertical plate 61 and the placement cylinder 72. When the beginning of the tape exceeds the pressure plate 66, it stops. The clamping cylinder 62 extends on the vertical plate 61 and pushes the extrusion plate 63 down. When the extrusion plate 63 drops to contact the tape, it cooperates with the pressure plate 66 to clamp the tape. The limiting block 65 drops together with the extrusion plate 63. The displacer 4 is started inside the protective shell 2, so that the displacer 4 drives the moving plate 5 to move along the guide rail 3 toward the direction close to the battery. The moving plate 5 drives the vertical plate 61 and the fixing seat 71 to move together, so as to transport the tape to be pasted.

[0071] Step 3: When the tape moves to the battery folding position, the beginning of the tape contacts the folding position, and the adjusting cylinder 643 extends on the vertical plate 61, so that the adjusting cylinder 643 pushes the adjusting plate 64 to rotate through the supporting plate 645. As the adjusting plate 64 rotates on the vertical plate 61, the squeezing column 641 is driven to approach the tape opening position, so that the squeezing column 641 contacts the tape at the folding position and squeezes it. The squeezing column 641 is used to squeeze the tape so that the tape adheres to the battery folding position. At the same time, the clamping cylinder 62 contracts and drives the squeezing plate 63 to rise, and the tape clamped by the squeezing plate 63 and the pressure plate 66 is released. The displacer 4 drives the moving plate 5 to move in the opposite direction to reset, so that the tape is adhered to the folding position and is subjected to the pressure of the squeezing column 641. Then, the tape on the placement cylinder 72 rotates, thereby pulling the tape.

[0072] Step 4: When the tape is pasted, the clamping cylinder 62 drives the extrusion plate 63 to descend again, so that the extrusion plate 63 and the pressure plate 66 cooperate to clamp the tape, and the cutting cylinder 644 extends to push the cutting blade 642 close to the tape for cutting. After the tape is cut, the cutting cylinder 644 contracts on the support plate 645 to drive the cutting blade 642 away from the tape, and the adjusting cylinder 643 contracts on the vertical plate 61 to drive the support plate 645 to move, so that the support plate 645 drives the adjusting plate 64 to rotate on the vertical plate 61, thereby driving the extrusion column 641 away from the battery;

[0073] Step 5: Use the mounting plate 83 and the connecting plate 81 to fix the mounting tube 82 on the vertical plate 61, so that the air supply fan 84 generates wind inside the mounting tube 82 to discharge the wind from the mounting tube 82, and the wind flowing through the mounting tube 82 blows toward the battery, and the battery and the folding edge are cleaned with the wind flow, and the inner support plate 85 supports the inside of the mounting tube 82. When the tape is pasted, the air supply fan 84 stops working inside the mounting tube 82, so that the wind flow of the mounting tube 82 stops;

[0074] Step six: Use the fixing frame 862 to support the docking plate 861 inside the installation cylinder 82, so that the docking plate 861 clamps the purification box 86, and as the supply fan 84 works, the wind generated by the wind circulates inside the installation cylinder 82 and contacts the activated carbon inside the purification box 86 to purify the air, and as the air circulates inside the installation cylinder 82 and contacts the curved plate 864, the curved plate 864 is blown by the wind to rotate on the tray 863, so that the curved plate 864 rotates and knocks the purification box 86, and the purification box 86 is knocked by the curved plate 864 to drop the dust adhered to itself, and the middle solid column 865 supports the tray 863 on the purification box 86, so that the tray 863 and the middle solid column 865 cooperate to limit the installation position of the purification box 86.
