Description

Technical Field

[0002] New energy vehicle battery cell gluing equipment is a supporting device for the gluing operation of automobile battery cells. Nowadays, the use of new energy vehicles is increasing. Automobile battery cells are an important component and play a driving role. When the battery cells are processed, their outer surfaces need to be glued. With the continuous development of science and technology, people's requirements for the manufacturing process of new energy vehicle battery cell gluing equipment are getting higher and higher.

[0003] For example, publication number CN113241470B discloses a new energy vehicle battery cell gluing device, which includes a device body, a conveyor belt, a waste box and a laminating station. The laminating station is located inside the device body, and the conveyor belt passes through the laminating station. A support frame, a positioning base plate and a mounting bracket are installed at the upper end of the laminating station. A loading box, a loading mechanism, a material belt and a protective frame are installed at the rear end of the laminating station. The material belt is fixedly connected to both sides of the laminating adhesive.

[0004] This patent uses a cell positioning mechanism, a tape adsorption mechanism, and a tape cutting mechanism to facilitate better positioning of automotive cells and prevent movement during gluing. Before the cell gluing process, multiple electrodes are bonded to each other with slurry to form a cell. However, the solid content of the slurry is uneven. After the cell is assembled and formed, slight undulations will appear on its surface. When entering the gluing process, due to the poor flatness of the cell surface, the edges of the colloid are prone to warping during the gluing operation, which will ultimately affect the output quality of the cell.

[0029] A method for gluing a new energy vehicle battery cell, characterized in that it comprises the following steps:

[0030] S1: The battery cells are placed in the inner cavity of the base cabinet. At this time, the proximity switch detects the loading position and quantity of the battery cells entering the inner cavity of the base cabinet. If an abnormal position or quantity is detected, an alarm is issued through the control module to prompt operation. When the battery cells pass through the proximity switch smoothly, the equipment continues to operate;

[0031] S2: The detection unit starts, emitting infrared rays that are reflected from the surface of the battery cell and received by the infrared receiving module. The information processing module analyzes and processes the information to obtain information such as the flatness of the battery cell surface. If the battery cell surface is uneven, the control module adjusts the parameters of subsequent gluing and compaction according to preset rules.

[0032] S3: The glue-applying mechanism starts working, evenly applying the glue to the cell surface at the set speed and trajectory. During the gluing process, the glue head adjustment component monitors the supply of glue in real time to ensure a stable glue quantity. The glue pressing column performs preliminary compaction on the applied glue to ensure initial adhesion between the glue and the cell surface.

[0033] S4: The heat drying mechanism starts to work. The air guide box adjusts the power of the fan according to the preset temperature curve to keep the temperature inside the heat drying mechanism within the appropriate range. At the same time, several symmetrically arranged heating plates are started to promote the flow of hot air in the heat drying mechanism, ensuring that the surface of the battery cell is heated evenly, accelerating the curing of the rubber material, and improving the bonding strength between the rubber material and the battery cell.

[0034] S5: The gluing auxiliary mechanism starts working. The second motor drives the reciprocating screw to rotate, so that the connecting seat moves back and forth on the outside of the reciprocating screw. At the same time, the first electric push rod drives the third and fourth connecting columns to rise and fall according to the height adjustment of the battery cell. The glue pressing roller connected to the fourth connecting column contacts the surface of the battery cell. The edges of the front and rear ends of the glue pressing rollers symmetrically arranged on both sides are the maximum distance between the front and rear ends of the battery cell surface, thereby smoothing the glue on the surface of the battery cell. During the compaction process, hot air is blown downward through the air roller body in the inner cavity of the glue pressing roller, which assists the compaction step. The range adjustment side plate allows the air roller body to adjust the air outlet range according to different degrees of warping. At the same time, due to the stickiness of the glue during the compaction process, the glue pressing roller may stick to the surface, thereby affecting the compaction. The scraper chamber scrapes the glue on the surface of the continuously rotating glue pressing roller, and the third motor and push plate collect the residual glue. During this process, the air knife body blows away dust and impurities that may exist on the surface of the uncompacted glue.

[0035] The present invention is beneficial in that:

[0036] 1. The present invention utilizes a structural design of a glue-applying auxiliary mechanism. A first electric push rod drives the third and fourth connecting posts to rise and fall according to the height of the battery cell. A glue-applying roller connected to the fourth connecting post contacts the surface of the battery cell. The symmetrically positioned front and rear edges of the glue-applying rollers maximize the distance between the front and rear ends of the battery cell surface, thereby smoothing the glue on the battery cell surface and improving battery cell output quality.

[0037] 2. The present invention utilizes a structural design of the adhesive application assisting mechanism. During the compaction process, hot air is blown downward through the air roller body within the cavity of the adhesive roller, assisting the compaction step. The range-adjusting side panels allow the air roller body to adjust the air outlet range according to varying degrees of edge warping. Furthermore, due to the stickiness of the adhesive during the compaction process, the adhesive may stick to the surface of the adhesive roller, thus affecting compaction. The scraper chamber scrapes away the adhesive from the rotating adhesive roller surface, and the third motor and push plate collect any remaining adhesive.

[0038] 3. The present invention adopts the structural design of the detection unit and the heat drying mechanism. By emitting infrared rays to irradiate the surface of the battery cell and then reflecting them, the infrared receiving module receives them, and the information processing module performs analysis and processing to obtain information such as the flatness of the battery cell surface. If the surface of the battery cell is uneven, the control module adjusts the parameters of subsequent gluing and compaction according to preset rules. The air guide box adjusts the power of the fan according to the preset temperature curve to keep the temperature in the heat drying mechanism within an appropriate range. At the same time, several symmetrically arranged heating plates are started to promote the flow of hot air in the heat drying mechanism, ensuring that the surface of the battery cell is heated evenly, accelerating the curing of the adhesive, and improving the bonding strength between the adhesive and the battery cell.

[0055] Both ends of the fourth connecting column 807 are fixedly connected to an air roller body 818 via an air roller shaft 817;

[0056] During operation, the first electric push rod 805 drives the third connecting column 806 and the fourth connecting column 807 to rise and fall according to the height adjustment of the battery cell. The glue pressing roller 808 connected to the fourth connecting column 807 contacts the surface of the battery cell.

[0057] Furthermore, the translation assembly includes a first fixed column 801, which is fixedly connected to the base cabinet 1, and a second motor 802 is fixed to one end of the first fixed column 801.

[0059] Furthermore, the gluing auxiliary mechanism 8 further includes a scraper magazine 809, which is fixedly connected to the front and rear ends of the third connecting column 806.

[0060] The front end of the inner cavity of the scraper chamber 809 is movably connected to a push plate 815, and the inner cavity of the scraper chamber 809 is provided with a glue groove 816;

[0061] During operation, the surface of the rubber pressing roller 808 may be stuck with colloid due to the stickiness of the colloid during the compaction process, thus affecting the compaction. The scraper bin 809 is used to scrape off the colloid on the surface of the continuously rotating rubber pressing roller 808. Secondly, the push plate 815 is connected to the inner cavity of the scraper bin 809 through the cylinder. The push plate 815 moves back and forth in the inner cavity of the scraper bin 809 along the bottom end of the partition plate 814 on the left and right sides of the cylinder. Finally, the residual colloid is collected by the third motor 811 and the push plate 815.

[0062] Furthermore, the gluing auxiliary mechanism 8 further includes a range-adjusting side plate 819 , which is movably connected to the bottom sides of the left and right ends of the air roller body 818 ;

[0063] The left and right ends of the air roller body 818 are fixedly connected to air roller side columns 820, the bottom ends of the air roller side columns 820 are hinged to a second electric push rod 821, the bottom ends of the second electric push rod 821 are fixedly connected to a second fixed column 822, and the second electric push rod 821 is fixedly connected to the top end of the range adjustment side plate 819 through the second fixed column 822;

[0064] The top sides of the front and rear ends of the air roller shaft 817 are fixedly connected to air roller side shielding plates 823, and the air roller side shielding plates 823 are fixedly connected to the inner cavities of the top sides of the front and rear ends of the rubber pressing roller 808;

[0065] During operation, during the compaction process, hot air is blown downward through the air roller body 818 in the inner cavity of the rubber roller 808, which assists the compaction step, and the range adjustment side plate 819 allows the air roller body 818 to adjust the air outlet range according to different degrees of warping.

[0066] Furthermore, the gluing auxiliary mechanism 8 also includes an air knife connecting shaft 824, which is fixedly connected to the left end of the first fixed column 801. The bottom side of the air knife connecting shaft 824 is fixedly connected to an air knife air inlet pipe 825. Two air knife air inlet pipes 825 are symmetrically arranged, and the two symmetrically arranged air knife air inlet pipes 825 are connected through an air knife body 826.

[0067] During operation, the air knife body 826 is used to blow away dust and impurities that may exist on the surface of the uncompacted colloid.

[0068] Working principle: The glue-applying auxiliary mechanism 8 starts to work, and the second motor 802 drives the reciprocating screw 803 to rotate, so that the connecting seat 804 moves back and forth on the outside of the reciprocating screw 803. At the same time, the first electric push rod 805 drives the third connecting column 806 and the fourth connecting column 807 to rise and fall according to the height adjustment of the battery cell.

The scraper chamber 809 is used to scrape the colloid on the surface of the continuously rotating pressing roller 808, and then the third motor 811 drives the fan blades 813 to suck the scraped colloid upward. During the suction process, due to the action of the partition plate 814, the glue accumulates on the lower surface of the partition plate 814. Then, the upper end of the push plate 815 is in close contact with the lower surface of the partition plate 814. During the forward and backward movement, the push plate 815 returns the colloid accumulated on the lower surface of the partition plate 814 to the rear end, and pushes the residual colloid into the groove at the rear end of the scraper top plate 810. During this process, the air knife body 826 is used to blow away the dust and impurities that may exist on the surface of the colloid that has not been compacted, so as to finally achieve the effect of smoothing the edge of the colloid and improve the output quality of the battery cell.

[0069] Example 2

[0070] See also Figure 1-Figure 5 As shown, Comparative Example 1 is another embodiment of the present invention, further comprising a detection unit 2: the inner cavity of the base cabinet 1 is fixedly connected with the detection unit 2;

[0071] The detection unit 2 includes an information processing module 201, which is fixedly connected to the inner cavity of the base cabinet 1. The top of the information processing module 201 is fixedly connected to an infrared receiving module 202, and one end of the infrared receiving module 202 is fixedly connected to an infrared transmitting module 203;

[0072] During operation, the information processing module 201 first completes the system initialization work, performs self-inspection on the connected infrared receiving module 202 and infrared transmitting module 203 to ensure that the communication between each module is normal, and at the same time, loads the pre-set test parameters. When the infrared receiving module 202 starts to transmit the infrared signal data reflected by the surface of the battery cell, the information processing module 201 quickly receives this data at the set sampling frequency, first performs preliminary filtering on the data to remove abnormal noise data points caused by environmental interference and other factors, and converts the infrared signal data after preliminary processing into actual flatness data of each point on the surface of the battery cell according to a pre-established mathematical model. These actual data are then compared and analyzed with the standard flatness data range to determine whether the flatness of the battery cell surface is within the qualified range. Based on the comparison and analysis results, a detailed test report is generated. The report content includes basic information of the battery cell (such as model, batch, etc.), flatness data of each test point, and overall flatness evaluation conclusion (qualified or unqualified).

[0073] Furthermore, a gluing mechanism 5 is fixedly connected to the inner cavity of the base cabinet 1;

[0074] The glue applying mechanism 5 includes a first connecting column 501, which is fixedly connected to the inner cavity of the base cabinet 1. The rear end of the first connecting column 501 is fixedly connected to a glue roll column 502.

[0075] The rear end of the first connecting post 501 is fixedly connected to a glue head adjustment assembly 506 , and the rear end of the first connecting post 501 is fixedly connected to a glue pressing post 507 ;

[0076] During operation, the first connecting column 501 is firmly connected to other components, and the glue roll column 502 carries the glue roll. As the various components operate, the glue on it gradually unfolds and continuously supplies glue for the gluing process. The glue unfolded from the glue roll column 502 is transferred through the glue transfer joint 503. The transfer joint guides the glue to the glue post 504 and may position, adjust the direction or tension of the glue to ensure that it arrives at the gluing position accurately. The first motor 505 prompts the glue roll column 502 to rotate and release glue. Under power drive, the glue post 504 adheres the transferred glue to the surface of the target object. The glue head adjustment component 506 plays a role in the glue head on the glue post 504. The glue head position and angle can be adjusted according to different gluing requirements to ensure the quality of gluing. After the gluing is completed, the glue pressing column 507 follows up the operation and applies pressure to the glued glue. Through the compaction action, the glue and the surface of the object are tightly adhered, the air in between is squeezed out, and the firmness and stability of the glue are enhanced.

[0077] Furthermore, a heat drying mechanism 7 is fixedly connected to the inner cavity of the bottom cabinet 1;

[0078] The drying mechanism 7 includes a fan 701, which is fixedly connected to the inner cavity of the bottom cabinet 1. The bottom end of the fan 701 is fixedly connected to an air duct 702, the bottom end of the air duct 702 is fixedly connected to an air guide box 703, and the bottom end of the air guide box 703 is fixedly connected to a heating plate 704. A plurality of heating plates 704 are symmetrically arranged.

[0079] The top of the air guide box 703 is fixedly connected to a second connecting column 705, and four second connecting columns 705 are symmetrically arranged;

[0080] During operation, the second connecting column 705 is used to connect the air guide box 703 and the inner cavity of the base cabinet 1. The fan 701 serves as a power source. After startup, the air flow is transmitted to the air guide box 703 through the air guide duct 702. The air guide box 703 guides the air flow so that the air flow can blow toward the heating plate 704. When the air flow distributed by the air guide box 703 blows through the heating plate 704, it absorbs heat to form hot air, and then heats the surface of the battery cell passing directly below it.

[0081] Furthermore, the inner cavity of the left end of the bottom cabinet 1 is fixedly connected to a horizontal axis 3, and the bottom end of the horizontal axis 3 is fixedly connected to a proximity switch 4, and four proximity switches 4 are symmetrically arranged;

[0082] The inner cavity of the bottom cabinet 1 is fixedly connected with the detection module 6, and the top of the bottom cabinet 1 is fixedly connected with the second horizontal axis 9, which is used to connect the detection unit 2 and the inner cavity of the bottom cabinet 1;

[0083] The inner cavity of the bottom cabinet 1 is provided with a conveyor belt 10, the left end of the bottom cabinet 1 is fixedly connected to the control module 11, and the top end of the bottom cabinet 1 is fixedly connected to the protective frame 12;

[0084] When in operation, a high-frequency oscillation circuit is provided inside the proximity switch 4. When the circuit is in operation, an alternating magnetic field is generated on the detection surface. Taking the inductive proximity switch 4 as an example, when current passes through the internal coil, an alternating magnetic field is formed. This magnetic field spreads outward. When the battery cell as the detection object enters the range of the alternating magnetic field, eddy currents are generated inside the battery cell, and the eddy currents generate their own magnetic field. This magnetic field interacts with the alternating magnetic field generated by the proximity switch 4, causing the parameters of the oscillation circuit inside the proximity switch 4 to change, such as inductance and quality factor. The circuit inside the proximity switch 4 will detect and process the changes in the oscillation circuit parameters. When the parameter changes reach a certain threshold, the conversion circuit inside the proximity switch 4 will convert this change into an electrical signal, thereby triggering a switch signal. When the battery cells are placed on the conveyor belt 10 in the inner cavity of the base cabinet 1, the proximity switch 4 detects their position and quantity. Once an abnormal position or quantity is detected, a signal is sent to the control module 11. The control module 11 immediately issues an alarm, prompting the operator to take action. If the battery cells pass normally, the equipment continues the subsequent work process. The infrared emission module 203 in the detection unit 2 emits infrared rays. After being irradiated on the surface of the battery cell, the reflected light is received by the infrared receiving module 202. The information processing module 201 processes the received infrared signal data. First, it quickly receives the data at the set sampling frequency, and then removes the abnormal noise data points caused by environmental interference through filtering. Then, according to the pre-established mathematical model, the processed signal data is converted into the actual flatness data of each point on the surface of the battery cell, and compared with the standard flatness data range to determine whether the surface flatness of the battery cell is qualified. According to the surface flatness test results of the battery cell, in the tape feeding device, the unwinding roller supplies For the tape with release paper, the pulling mechanism cooperates with the first peeling component to remove the release paper, and the tape cutting mechanism cuts the tape to form a tape segment of predetermined length. The control module 11 can adjust the operating parameters of these components, such as the moving speed of the linear drive module in the pulling mechanism, the cutting position of the cutter in the tape cutting mechanism, etc., to change the length, position accuracy and other parameters related to the gluing structure, so as to adapt to the surface condition of the battery cell and adjust the gluing speed and trajectory of the subsequent gluing mechanism 5 and the compaction parameters of the gluing auxiliary mechanism 8, so that the glue can better fit the surface of the battery cell and improve the output quality of the battery cell.

[0085] Working principle: The battery cells are placed on the upper side of the conveyor belt 10 in the inner cavity of the bottom cabinet 1. At this time, the proximity switch 4 detects the loading position and quantity of the battery cells entering the inner cavity of the bottom cabinet 1. If an abnormal position or quantity is detected, an alarm is issued through the control module 11 to prompt operation. When the battery cells pass through the proximity switch 4 smoothly, the equipment continues to run, the detection unit 2 is started, and the infrared ray is emitted to the surface of the battery cells and then reflected and received by the infrared receiving module 202. The information processing module 201 performs analysis and processing to obtain information such as the flatness of the battery cell surface. If the surface of the battery cell is uneven, the control module 11 adjusts the parameters of subsequent gluing and compaction according to the preset rules. The gluing mechanism 5 starts working, and the glue is evenly attached to the surface of the battery cell according to the set speed and trajectory. During the gluing process, the glue head adjustment component 506 monitors the supply of glue in real time to ensure a stable glue quantity. The glue pressing column 507 performs preliminary compaction on the glue to make the glue and the battery cell surface initially bonded. The heat drying mechanism 7 starts working, and the air guide box 703 adjusts the power of the fan 701 according to the preset temperature curve to keep the temperature in the heat drying mechanism 7 within a suitable range. At the same time, several symmetrically arranged heating plates 704 are started to promote the flow of hot air in the heat drying mechanism 7, ensuring that the surface of the battery cell is heated evenly, accelerating the curing of the glue, and improving the bonding strength between the glue and the battery cell.

[0086] like Figure 1-9 As shown, a new energy vehicle battery core gluing method is characterized by comprising the following steps:

[0087] S1: The battery cell is placed in the inner cavity of the base cabinet 1. At this time, the proximity switch 4 detects the loading position and quantity of the battery cell entering the inner cavity of the base cabinet 1. If an abnormal position or quantity is detected, an alarm is issued through the control module 11 to prompt operation. When the battery cell passes the proximity switch 4 smoothly, the equipment continues to operate;

[0088] S2: The detection unit 2 is activated, and infrared rays are emitted to the surface of the battery cell, which is then reflected and received by the infrared receiving module 202. The information processing module 201 analyzes and processes the information to obtain information such as the flatness of the battery cell surface. If the battery cell surface is uneven, the control module 11 adjusts the parameters of subsequent gluing and compaction according to preset rules.

[0089] S3: The glue applying mechanism 5 starts working and applies the glue evenly to the surface of the battery cell according to the set speed and trajectory. During the glue applying process, the glue head adjustment component 506 monitors the supply of glue in real time to ensure a stable glue amount. The glue pressing column 507 performs preliminary compaction on the applied glue to ensure that the glue is initially bonded to the surface of the battery cell.

[0090] S4: The drying mechanism 7 starts working. The air guide box 703 adjusts the power of the fan 701 according to the preset temperature curve to keep the temperature inside the drying mechanism 7 within a suitable range. At the same time, the symmetrically arranged heating plates 704 are activated to promote the circulation of hot air inside the drying mechanism 7, ensuring that the surface of the battery cell is heated evenly, accelerating the curing of the adhesive, and improving the bonding strength between the adhesive and the battery cell.

[0091] S5: The glue-sticking auxiliary mechanism 8 starts to work, and the second motor 802 drives the reciprocating screw 803 to rotate, so that the connecting seat 804 moves back and forth on the outside of the reciprocating screw 803. At the same time, the first electric push rod 805 drives the third connecting column 806 and the fourth connecting column 807 to rise and fall according to the height adjustment of the battery cell. The glue-sticking roller 808 connected to the fourth connecting column 807 contacts the surface of the battery cell. The edges of the front and rear ends of the glue-sticking roller 808 symmetrically arranged on both sides are the maximum distance between the front and rear ends of the battery cell surface, thereby smoothing the colloid on the surface of the battery cell. In the process of compaction, the air roller body in the inner cavity of the glue-sticking roller 808 818 blows out hot air downward, which assists the compaction step, and the range-adjusting side plate 819 allows the air roller body 818 to adjust the air outlet range according to different degrees of warping. At the same time, during the compaction process, the colloid is sticky and the surface of the rubber pressing roller 808 may be stuck with colloid, which affects the compaction. The scraper magazine 809 scrapes the colloid on the surface of the continuously rotating rubber pressing roller 808, and the third motor 811 and the push plate 815 collect the residual colloid. In this process, the air knife body 826 is used to blow away the dust and impurities that may exist on the surface of the colloid that has not been compacted.
