Description

Technical Field

[0001] The present invention relates to the technical field of battery gluing, and in particular to a battery gluing device. Background Art

[0002] The battery gluing device should be the equipment used for gluing during the battery production process. According to the report, the battery automatic gluing machine consists of a cutter, a gluing head, a conveyor belt and a control system, which can automatically complete the processes of loading, preparing glue, gluing and unloading, which is very important for the safety and reliability of the battery, especially in electric vehicles. It is mentioned that the gluing machine has an anti-bubble mechanism, which uses a heated roller to reduce bubbles and improve the uniformity of gluing. It solves the problem of gluing batteries of different sizes, and absorbs the tape through a buffer spring and an air pump.

[0003] In the prior art, the conventional ultrasonic welding and glue pasting adopts a segmented, single-station positive and negative electrode glue pasting method, which is inefficient and has complicated steps. Figure 1 As shown, the traditional glue sticking method is to suck the tape and drive the tape to stick on a, b, c, d, e, f, g, and h at the end of the battery cell respectively. It takes 8 consecutive stickings to fill the weld mark at the end of the battery cell, and the tape is only stuck near the weld mark of the battery cell, which cannot completely cover the end face of the entire battery cell, and the problem of missing weld marks is prone to occur; in addition, the existing overall glue sticking is a turntable glue sticking. When a problem occurs at one station, other stations on the turntable will be suspended, which seriously affects the glue sticking efficiency, pass rate, and OEE of the entire line.

[0004] Therefore, the present application aims to solve the problem that segmented gluing affects the overall gluing efficiency and also causes the problem of missing welding marks on the battery core. Summary of the invention

[0005] The main purpose of the present invention is to provide a battery gluing device, which aims to improve the gluing efficiency of battery cells and at the same time increase the coverage of the adhesive tape on the battery cell weld marks.

[0006] In order to achieve the above-mentioned object, the present invention provides a battery gluing device, including a gluing frame, and also including:

[0007] A glue preparation component, which is used to provide adhesive tape for the battery cell;

[0008] A cutting assembly, which can extend along a surface of the tape head perpendicular to the adhesive preparation assembly and is used to cut off the tape head;

[0009] The adhesive sticking assembly is placed on the side of the tape head away from the cutting assembly and absorbs the tape head cut by the cutting assembly, and comprises:

[0010] A mounting plate, which rotates with the adhesive sticking frame;

[0011] At least one glue suction component is placed on the mounting plate. The rotation of the mounting plate can drive the glue suction component to face the tape head or the battery core. The glue suction component includes one or two glue suction groups. The glue suction groups can drive the two ends of the glue suction head to press and fit at different heights of the battery core.

[0012] The glue preparation component transports the tape head to the cutting component, and after the tape head is cut by the cutting component, it is adsorbed by the glue suction part in the glue sticking component. After the glue suction part adsorbs multiple tapes, the glue suction part turns to the battery cell through the mounting plate, and presses the adsorbed tape to fit on the weld marks of different heights of the battery cell. The overall Z-shaped bonding is adopted to make the tape fit on the end of the battery cell and the connecting piece, which improves the overall work efficiency, and also increases the coverage of the tape on the end of the battery cell to avoid the problem of missing bonding of the battery cell.

[0013] Furthermore, the glue suction group includes a glue suction head A and a glue suction head B connected to the mounting plate. When the glue suction head A and the glue suction head B face the tape head, the glue suction head A and the glue suction head B can approach and absorb the tape head. When the glue suction head A and the glue suction head B face the battery core, the glue suction head A and the glue suction head B can approach the battery core and press the tape head to fit at different heights of the battery core.

[0014] In the above scheme, the glue suction head A is against h and shrinks toward the mounting plate under the action of the second elastic member and the linear guide rail, which can prevent the battery cell from being subjected to excessive stress. The glue suction head B gradually drives the tape to fit the end of the battery cell until the glue suction head B is pressed at g, so that the tape completely covers the weld mark of the battery cell. This lamination method is more efficient than the original multiple lamination method, and the tape can better cover the weld mark of the battery cell, cover a wider range, and can better prevent dust.

[0015] Furthermore, one end of the glue suction head B close to the glue suction head A is provided with a yield groove.

[0016] Furthermore, when two adhesive absorbing components are used, the two adhesive absorbing components are respectively placed on opposite sides of the mounting plate, and when one of the adhesive absorbing components absorbs the adhesive tape head, the other adhesive absorbing component presses the adhesive tape head to fit onto the battery core.

[0017] Furthermore, the cutting assembly includes a linear drive connected to the glue sticking frame, a fixed plate connected to the output end of the linear drive, and a cutter and a glue pressing block connected to the fixed plate. The glue pressing block presses the tape head onto the glue suction group, and the cutter cuts the tape head.

[0018] Furthermore, the cutter moves along the width direction of the tape head to cut, or the cutter cuts perpendicularly to the surface of the tape head.

[0019] Furthermore, a groove is provided at one end of the glue pressing block close to the glue suction group.

[0020] Furthermore, a first elastic member is provided between the fixing plate and the glue pressing block, so that the glue pressing block can be moved close to or away from the fixing plate.

[0021] Furthermore, the cutting assembly includes a pressing block and a pressure block, both of which are connected to the glue sticking frame, and the pressing block can approach or move away from the pressure block to press the tape head into position.

[0022] Furthermore, it includes a glue clamping component connected to the glue applying frame, and the glue clamping component includes a telescopic part fixed on the glue applying frame and a clamping part connected to the output end of the telescopic part. The telescopic part can drive the clamping part to move closer to or away from the pressing block and the pressure block, and pull the tape head between the two through the clamping part.

[0023] The above technical solution has the following advantages:

[0024] The present invention adopts the joint action of a glue preparation component, a cutting component and a glue sticking component. The glue preparation component transports the tape head to the cutting component, and after the tape head is cut by the cutting component, it is adsorbed by a glue suction component in the glue sticking component. After the glue suction component adsorbs multiple tapes, the glue suction component turns to the battery cell through a mounting plate, and presses the adsorbed tape to be adhered to the welding marks of different heights of the battery cell. The whole adopts a Z-shaped adhesion, so that the tape is adhered to the end and the connecting piece of the battery cell, which improves the overall work efficiency, and also improves the coverage of the tape on the end of the battery cell to avoid the problem of missing adhesion of the battery cell.

[0025] Avoid using the original tape-sticking method, where the tape is stuck on different weld marks of the battery cell in sequence. Use a separate tape-sticking design to avoid the problem of linkage in the turntable design, which may cause malfunctions and downtime.

[0026] The present invention adopts a piece of adhesive tape attached to the connecting piece and the end of the battery core to complete the welding and printing of the battery core, reducing the number of cutting times of the subsequent cutter. At the same time, two relatively designed adhesive suction parts, when one of the adhesive suction parts adsorbs the adhesive tape head, the other adhesive suction part presses the adhesive tape to adhere to the battery core, which can improve the overall work efficiency and improve the synchronous operation of the adhesive suction head A and the adhesive suction head B adsorbing the adhesive tape head and pressing and pasting the adhesive tape, greatly saving the time of taking out and pasting the adhesive tape.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0038] By this application Figure 1 As shown, the prior art has a glue suction head to absorb the tape, so that the tape is pressed and attached to a, b, c, d, e, f, g, and h in sequence, so that each battery cell glue needs to be completed 8 times, and the tape needs to be attached to the welding mark of the battery cell. Each time the glue is attached, the tape needs to be cut once, resulting in low production efficiency. To this end, the present application provides a solution to the above problems, which is as follows:

[0039] like Figure 2 , Figure 5 and Figure 7As shown, a battery gluing device includes a gluing frame 5, and also includes a glue preparation component 2, a cutting component 3 and a gluing component 4 connected to the gluing frame 5, the glue preparation component 2 is used to provide tape for the battery cell; the cutting component 3 can extend along the surface of the tape head perpendicular to the glue preparation component 2, and is used to cut the tape head; the gluing component 4 is placed on the side of the tape head away from the cutting component 3, and absorbs the tape head cut by the cutting component 3, the gluing component 4 includes a mounting plate 42 and at least one glue suction component 41, the mounting plate 42 rotates with the gluing frame 5; the glue suction component 41 is placed on the mounting plate 42, and the rotation of the mounting plate 42 can drive the glue suction component 41 to face the tape head or the battery cell, the glue suction component 41 includes one or two glue suction groups, and the glue suction groups can drive the two ends of the glue suction head to be pressed and attached to different heights of the battery cell.

[0040] The glue sticking rack 5 is used to carry the glue preparation component 2, cutting component 3 and glue sticking component 4 of the present application. The glue preparation component 2 provides tape for the present application, such as brown tape. The glue sticking rack 5 is also provided with a translation module 51, which moves the glue sticking position between different workstation fixtures to improve the convenience of workstation adjustment; the cutting component 3 is used to cut the tape head extending from the brown tape, and transfer the cut tape to the glue sticking component 4. After the glue sticking component 4 absorbs the tape, the cut tape can be pressed and stuck on the battery cell to complete the tape sticking operation; a third motor 43 is installed on the glue sticking rack 5, and the output shaft of the third motor 43 is fixed to the mounting plate 42, so that the third motor 43 can drive the mounting plate 42 to rotate, so that the mounting plate 42 drives the glue suction component 41 to switch from the tape head to the battery cell, so as to stick tape to the battery cell or switch from the battery cell to the tape head, so as to take the tape.

[0041] Specifically, Figures 2 to 5 As shown, the glue preparation assembly 2 includes a first film roll 21 and a second film roll 22. The tape head is the free end of the first film roll or the second film roll after being pulled. The first film roll 21 and the second film roll 22 are both rotatably assembled on the glue sticking rack 5 through a rotating shaft. The glue sticking rack 5 is provided with a first motor 211 and a second motor 221 in sequence according to the positions of the first film roll 21 and the second film roll 22. The first motor 211 and the second motor 221 respectively drive the rotating shafts of the first film roll 21 and the second film roll 22 to realize the unwinding operation.

[0042] The glue preparation assembly 2 also includes a tensioning member 23, which is composed of a plurality of tensioning wheels rotatably arranged on the glue sticking frame 5, so that the tapes of the first film roll 21 and the second film roll 22 pass through the plurality of tensioning wheels in sequence and are guided to the cutting assembly 3 by the tensioning wheels. The tensioning member 23 can adopt a spiral tensioning device, a heavy hammer tensioning device, a cylinder tensioning device, etc. The specific usage method can be selected by technicians in this field.

[0043] A control component 1 is also installed on the glue sticking rack 5. The control component 1 may include a number of solenoid valves 11 and valve islands 12 to control the glue preparation component 2, cutting component 3 and glue sticking component 4 of the present application. In addition, it also includes a number of other electronic control devices on the glue sticking rack 5. PLC regulation is preferably used to achieve accurate control of different components to achieve mutual synergy.

[0044] like Figures 6 to 8 As shown, the glue suction group includes a glue suction head A411 and a glue suction head B412 connected to the mounting plate 42. When the glue suction head A411 and the glue suction head B412 face the tape head, the glue suction head A411 and the glue suction head B412 can approach and absorb the tape head. When the glue suction head A411 and the glue suction head B412 face the battery cell, the glue suction head A411 and the glue suction head B412 can approach the battery cell and press the tape head to fit at different heights of the battery cell. The glue sucking head A411 and the glue sucking head B412 can be close to or away from the mounting plate 42, so that the glue sucking head A411 or the glue sucking head B412 can move toward the mounting plate 42 when pressed. When the glue sucking head A411 and the glue sucking head B412 are not pressed, both of them extend outward. The surfaces of the glue sucking heads A411 and the glue sucking heads B412 are provided with a plurality of negative pressure holes. When the glue sucking heads A411 and the glue sucking heads B412 are close to the cutting group, the glue sucking heads A411 and the glue sucking heads B412 are moved away from the mounting plate 42. When the tape head is cut off by the component 3, the negative pressure holes of the adhesive suction heads A411 and B412 approach and absorb the tape head, so that the tape is absorbed on the adhesive suction heads A411 and B412. When the mounting plate 42 drives the adhesive suction heads A411 and B412 to rotate and face the battery core, the adhesive suction heads A411 and B412 gradually approach the battery core, so that one end of the tape is attached to the end of the battery core, and the other end is attached to the connecting sheet. Figure 1 shown.

[0045] As an implementation method of this application, Figure 7 As shown in the figure, an adjustment plate 47 is connected to the mounting plate 42, and a linear guide 45 and a second elastic member 46 are connected to the side of the adjustment plate 47 away from the mounting plate 42. A mounting block 44 is fixed to the slider of the linear guide 45, and the second elastic member 46 is located between the mounting block 44 and the adjustment plate 47. The second elastic member 46 is preferably in the form of a cylinder and a spring, so that the mounting block 44 can move along the linear guide 45, and the second elastic member 46 continuously applies pressure to the mounting block 44. The glue suction head A411 and the glue suction head B412 can be extended and retracted through the mounting block 44, so that the glue suction head A411 and the glue suction head B412 can both press the glue on the battery cell. In this application, it is preferred to connect the glue suction head A411 to the mounting block 44, and fix the glue suction head B412 to the adjustment plate 47, that is, only the glue suction head A411 can be extended and retracted, and the glue suction head B412 is in a fixed state. Figure 1As shown, when the process is in use, the glue suction head A411 rests on h and shrinks toward the mounting plate 42 under the action of the second elastic member 46 and the linear guide rail 45, which can prevent the battery cell from being subjected to excessive stress. The glue suction head B412 gradually drives the tape to fit the end of the battery cell until the glue suction head B412 is pressed on g, so that the tape completely covers the weld mark of the battery cell. This bonding method is more efficient than the original multiple bonding method, and the tape can better cover the weld mark of the battery cell, cover a wider range, and can better prevent dust.

[0046] The adjustment plate 47 can adjust the positions of the glue suction head A411 and the glue suction head B412 along the horizontal direction, so as to facilitate fine-tuning of the positions of the battery cells and the tape and improve the accuracy of the adjustment.

[0047] As an implementation method of this application, Figure 7 and Figure 8 As shown, a clearance groove 413 is provided at one end of the glue suction head B412 close to the glue suction head A411. The clearance groove 413 can be set as an inclined surface, and its specific shape can be designed according to needs, so that when the glue suction head B412 is close to the battery cell, the clearance groove 413 can smooth the tape, so that the tape can better fit the end of the battery cell, thereby improving the tightness of the fit at the end of the battery cell.

[0048] As an implementation method of this application, Figure 2 and Figure 7 As shown, multiple glue sucking parts 41 can be provided, but the present application preferably provides two. When two glue sucking parts 41 are used, the two glue sucking parts 41 are respectively placed on opposite sides of the mounting plate 42. When one of the glue sucking parts 41 absorbs the tape head, the other glue sucking part 41 presses the tape to fit the battery cell. This can improve the overall work efficiency and improve the synchronous operation of the glue sucking head A411 and the glue sucking head B412 sucking the tape head and pressing the tape. The glue sucking head A411 and the glue sucking head B412 of each glue sucking part 41 can be designed according to needs. The present application requires the glue sticking operation between two battery cells. Therefore, each glue sucking part 41 of the present application specifically has two groups of glue sucking heads A411 and glue sucking heads B412, and each group of glue sucking heads A411 and glue sucking heads B412 is used to stick to one of the battery cells.

[0049] like Figure 2 , Figure 5 and Figure 6As shown, the cutting assembly 3 includes a linear drive member 31 connected to the glue sticking frame 5, a fixed plate 37 connected to the output end of the linear drive member 31, and a cutter 35 and a glue pressing block 34 connected to the fixed plate 37. The glue pressing block 34 presses the tape head onto the glue suction group, and the cutter 35 cuts the tape head. The linear drive member 31 is used to drive the fixed plate 37 to move up and down, thereby driving the cutter 35 and the glue pressing block 34 to move closer to or away from the tape head. The linear drive member 31 can be a guide rail, a cylinder or an electric cylinder. When the fixing plate 37 is close to the tape head, the glue pressing block 34 presses the tape head tightly onto the glue absorbing head A411 and the glue absorbing head B412. At this time, the glue absorbing head A411 and the glue absorbing head B412 have adsorbed the tape head through the negative pressure hole, and after the tape head is pressed, the cutter 35 cuts the tape head to form multiple pieces of tape. Then the linear driving part 31 can drive the glue pressing block 34 to move upward, so that the multiple cut tapes are adsorbed on the glue absorbing head A411 and the glue absorbing head B412, and the subsequent battery cell gluing operation can be carried out.

[0050] As an implementation method of this application, Figure 2 , Figure 5 and Figure 6 As shown, the cutter 35 moves along the width direction of the tape head to cut or the cutter 35 cuts perpendicularly to the surface of the tape head. When the cutter 35 moves along the width direction of the tape head to cut, a cylinder or an electric cylinder is installed on the fixed plate 37, and the cutter 35 is driven to move back and forth by the cylinder or the electric cylinder, so that the cutter 35 cuts along the width direction of the tape head, so that the tape head is adsorbed on the glue suction head A411 and the glue suction head B412 after cutting.

[0051] In addition, a first elastic member 38 is provided between the fixed plate 37 and the glue pressing block 34, so that the glue pressing block 34 can be close to or away from the fixed plate 37. When the cutter 35 cuts perpendicularly to the surface of the tape head, the cutter 35 can be directly assembled on the fixed plate 37. When the fixed plate 37 moves downward, the glue pressing block 34 presses the tape head against the adsorption head A and the adsorption head B, and the cutter 35 continues to move downward, and a first elastic member 38 is provided between the glue pressing block 34 and the fixed plate 37, so that the glue pressing block 34 is gradually contracted by the first elastic member 38 until the cutter 35 cuts off the tape head. The first elastic member 38 is preferably in the form of a cylinder and a spring, and can also be in the form of a spring or rubber.

[0052] In both installation methods of the above-mentioned two cutters 35, a first elastic member 38 can be provided between the fixed plate 37 and the glue pressing block 34. When the first elastic member 38 is a cylinder and a spring arranged on the periphery of the cylinder, the end of the cylinder passes through the fixed plate 37, and a gasket 36 is installed on the fixed plate 37. The gasket 36 can adjust the expansion and contraction amount between the glue pressing block 34 and the fixed plate 37, so as to achieve fine adjustment of the pressing force during the process of taking the tape; because the glue suction head A411 and the glue suction head B412 are located on one side of the negative pressure hole and may be on different horizontal planes, the first elastic member 38 is needed to play a buffering role at this time to ensure that the tape head can be completely attached to the glue suction head A411 and the glue suction head B412, so that the tape head can be stably cut after being pressed.

[0053] like Figure 5 and Figure 6 As shown, in order to further improve the cutting effect of the tape head, a groove is provided at one end of the glue pressing block 34 close to the glue suction group. When the glue pressing block 34 is pressed against the glue suction head A411 and the glue suction head B412, the two ends of the groove are fitted with the tape head, reducing the fitting area between the tape and the glue pressing block 34, so as to avoid increasing the bonding ability between the tape head and the glue pressing block 34, causing the tape to adhere to the glue pressing block 34, and affecting the subsequent gluing work.

[0054] As an implementation method of this application, Figure 6 As shown, the cutting assembly 3 includes a pressing block 32 and a pressure block 33, both of which are connected to the glue sticking frame 5. The pressing block 32 can approach or move away from the pressure block 33 and press the tape head into position. The pressing block 32 and the pressure block 33 are located on the upper and lower sides of the tape head. When the tape head needs to be cut through the cutting assembly 3, a cylinder can be installed on the glue sticking frame 5, and the pressing block 32 is driven by the cylinder to move toward the pressure block 33, so that the pressing block 32 presses the tape head onto the pressure block 33, ensuring that the free end of the tape head is stable, which is convenient for the pressing and fixing of the glue pressing block 34, improves the cutting accuracy of the cutter 35, and facilitates the subsequent pulling of the tape head.

[0055] In order to further improve the pulling of the tape head, when the pressing block 32 and the pressure block 33 are pressed tightly, a plurality of wavy grooves or serrated strips are provided on the pressing block 32 so that the contact area between the pressing block 32 and the tape head can be reduced as much as possible when the pressing block 32 is pressed tightly, so as to prevent the tape head and the pressing block 32 from being too tightly bonded, thereby affecting the subsequent material removal of the tape head. At the same time, if the bonding is too tight, it will also affect the viscosity of the tape and the adhesive effect of the tape on the battery core weld mark.

[0056] like Figure 5 and Figure 6As shown, the present application includes a glue clamping component 6 connected to the glue sticking frame 5, and the glue clamping component 6 includes a telescopic member 62 fixed on the glue sticking frame 5 and a clamping member 61 connected to the output end of the telescopic member 62. The telescopic member 62 can drive the clamping member 61 to approach or move away from the pressing block 32 and the pressure block 33, and pull the tape head between the two through the clamping member 61, wherein the telescopic member 62 can adopt an electric cylinder, a pneumatic cylinder or a guide rail driven by a linear motor, and its output end can be connected to the clamping member 61, and the clamping member 61 can adopt a tape clamp, a tape clamp or a fixed clamp, etc., and the clamping member 61 is driven by the telescopic member 62 to move to the pressing block 32, and the tape head at the pressing block 32 is clamped and fixed, and then the telescopic member 62 contracts, and it drives the tape head to move to the bottom of the glue pressing block 34 through the clamping member 61, and subsequent cutting and adsorption operations can be carried out.

[0057] When in use, the first motor 211 and the second motor 221 respectively drive the first film 21 and the second film 22 to unwind, so that the tape is transported and pressed between the pressure block 33 and the pressing block 32, and then the telescopic member 62 drives the clamping member 61 to clamp the tape head. When the pressing block 32 rises, the telescopic member 62 drives the tape head to be pulled through the clamping member 61, so that the tape head is pulled and moved to the bottom of the cutting assembly 3.

[0058] The fixed plate 37 in the cutting assembly 3 moves downward, and the adhesive tape head is pressed onto the adhesive suction head A411 and the adhesive suction head B412 through the adhesive pressing block 34. At this time, the adhesive suction head A411 and the adhesive suction head B412 absorb the adhesive tape head through negative pressure, and the adhesive tape head is cut by the cutter 35 to be divided into four adhesive tapes. After the cutting is completed, the adhesive pressing block 34 moves upward, and the adhesive suction head A411 and the adhesive suction head B412 continue to absorb the adhesive tape through negative pressure to complete the cutting and material removal of the adhesive tape;

[0059] The third motor 43 drives the mounting plate 42 to rotate, so that the mounting plate 42 drives the glue suction heads A411 and B412 to turn from the tape heads to the battery cells, and drives the glue suction heads A411 and B412 to move toward the battery cells through the cylinder in the mounting plate 42. The tapes absorbed by the glue suction heads A411 and B412 are sequentially attached to the weld marks of the battery cells. The whole process is a Z-shaped glue sticking, which improves the tape sticking efficiency and covers a wider range of battery cell weld marks.
