Description

Technical Field

[0001] The present invention relates to the technical field of tab production and processing, and particularly relates to an automatic positioning induction heating device for tab production. Background Art

[0002] New energy vehicles have witnessed explosive growth. The high energy density and high safety requirements of power batteries have promoted the continuous increase in the penetration rate of polymer lithium-ion batteries (referred to as soft-pack lithium batteries, the same below). The advantages of soft-pack batteries lie in their light weight and good safety performance. The high energy density and high safety requirements of power batteries are expected to accelerate the increase in the penetration rate of soft-pack batteries in the new energy vehicle market. In 2016, soft-pack lithium batteries accounted for only 10% of the total power batteries, with a relatively low penetration rate. It is expected that soft-pack lithium batteries will account for about 38% of power batteries in 2020.

[0003] According to the "Medium- and Long-Term Development Plan for the Automotive Industry", by 2020, the specific energy of power battery monomers must reach 300 Wh / kg, strive to achieve 350 Wh / kg, and the system specific energy strive to reach 260 Wh / kg. Ternary batteries, especially high-nickel ternary batteries, have become the development direction of power batteries. By 2020, the demand for power batteries using ternary materials is expected to rise to 71.6 GWh, and the proportion will increase from the current 22% to over 70%. However, the higher the nickel content in ternary materials, the worse their stability, resulting in greater difficulty in the safety design of batteries. Currently, ternary materials are widely used in soft-pack batteries. Therefore, solving the safety of ternary materials in the later stage is a relatively urgent issue for soft-pack batteries.

[0004] Tabs are a kind of raw material for lithium-ion polymer battery products. Tabs are metal conductors drawn out from the positive and negative electrodes of the battery cell. Generally speaking, the ears at the positive and negative poles of the battery are the contact points during charge and discharge. During the manufacturing process of tabs, heating is a key step, mainly aiming to better bond the tab glue with the metal strip, thereby ensuring the sealing and safety of the battery.

[0005] The publicly disclosed Chinese patent with the publication number CN220023095U discloses a heating fixture for lithium battery tabs, which includes a fixture platform, a battery cell main body, and a positive side heating area and a right side heating area provided at the left and right ends of the fixture platform respectively; the left clamping block assembly includes an insulating area fixedly provided on the left side of the fixture platform, a fixed clamping block provided under the insulating area, and a movable clamping block whose bottom end is provided on the insulating area through a slider and moves relative to the fixed clamping block; electric heating blocks are respectively provided on the inner sides of the fixed clamping block and the movable clamping block. While the electric heating blocks clamp and position the positive tab and the right tab on the battery cell main body, the electric heating blocks are heated up by the heat energy generated by the operation of the thermocouple, and the heat on the electric heating blocks is respectively conducted to the positions of the left tab and the negative tab. It has the advantages of quickly positioning the battery cell main body, while performing charge and discharge operations on the positive tab and the negative tab on the battery cell main body through a simple structure, reducing the cost of charge and discharge operations on the lithium battery, and the quickness of positioning and clamping the lithium battery. This publicly disclosed patent heats the lithium battery tabs by means of contact heat conduction. Since heat conduction takes time, the heating times of each area of the tabs are not the same. Specifically, the area of the tab close to the electric heating block has a longer heating time and a higher temperature. Therefore, there is a problem of uneven heating.

[0006] The publicly disclosed Chinese patent with the publication number CN209767854U discloses an induction heating device for tabs, which is characterized in that: it includes a frame (4), a control panel (1), a processing area (2), and a power supply main unit (3) are fixed on the frame (4) from top to bottom. Among them, the power supply main unit (3) supplies power to the devices in the control panel (1) and the processing area (2). A processing table is provided on the processing area (2). A pre-processing product cartridge (2.1) and a post-processing product cartridge (2.2) are placed on the front side of the processing table. A suction cup mechanism (2.3) is provided on the processing table. The suction cup mechanism (2.3) is provided with a sliding track and a suction cup, and the suction cup can slide back and forth on the sliding track. A transmission mold (2.4) is provided below the suction cup mechanism (2.3). A processing area (2.5) is provided on the processing table at the rear side of the transmission mold (2.4). The transmission mold (2.4) can accurately move the tab to the processing area (2.5) for heating or pressing operations. After the processing is completed, the transmission mold (2.4) moves back to its original position. This publicly disclosed patent proposes an induction heating method, but the tab is not positioned during the heating process, and it is impossible to ensure that each tab is in the same position and posture during the heating process, which affects the stability of the product production quality. Summary of the Invention

[0007] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide an automatic positioning induction heating device for tab production. By arranging a blanking mechanism and two side positioning mechanisms on the heating station, the blanking mechanism can lift the tab placed on the transmission mechanism and transported by the feeding through the blanking plate and position its front end through the baffle. The two side positioning mechanisms can position the two side ends of the tab through the positioning plate after the tab is lifted. The three-end positioning can ensure that each tab is in the same position and posture during the heating process, thus ensuring the stability of the product production quality. When the two side positioning mechanisms position the two side ends of the tab, the tab can be in a suspended state, greatly reducing the shadow area during tab heating, which is beneficial to improving the heating effect and heating efficiency of the tab, and can solve the problem in the prior art that it is impossible to ensure that each tab is in the same position and posture during the heating process, affecting the stability of the product production quality.

[0008] To achieve the above object and other related objects, the present invention provides an automatic positioning induction heating device for tab production, including a workbench, on which two parallel transmission mechanisms are provided, and tab products are simultaneously placed on the two transmission mechanisms and transported for feeding;

[0009] On the workbench, a heating station, an inspection station, a kicking station, and a blanking station are successively arranged along the transmission direction of the transmission mechanism;

[0010] On the heating station, a blanking mechanism and two side positioning mechanisms are provided. The blanking mechanism is installed at the lower end of the workbench and located between the two transmission mechanisms. The two side positioning mechanisms are installed on the opposite sides at the upper end of the workbench. The blanking mechanism cooperates with the two side positioning mechanisms to perform three-end positioning on the tab products. An elevating module is also provided on the heating station, and an induction heating coil is installed at the elevating end of the elevating module;

[0011] On the inspection station, a vision inspection camera is provided. The vision inspection camera is installed above the workbench through a gantry for detecting the processing state of the tab products;

[0012] On the kicking station, a kicking mechanism and an NG bin are provided. The kicking mechanism includes a kicking cylinder and a kicking plate installed at the output end of the kicking cylinder. The kicking mechanism is installed at the upper end of one side of the workbench, and the NG bin is installed on the other side of the workbench;

[0013] On the blanking station, an OK bin is provided.

[0014] In an embodiment of the present invention, the two transmission mechanisms are the same mechanism, and both include:

[0015] Stepper motor;

[0016] A driving pulley connected to the output end of the stepper motor;

[0017] A plurality of driven pulleys;

[0018] A conveyor belt that simultaneously sleevs the driving pulley and a plurality of driven pulleys.

[0019] In an embodiment of the present invention, the blanking mechanism includes a blanking cylinder and a blanking plate installed at the output end of the blanking cylinder. A baffle is provided at the front end of the blanking plate for positioning the front end of the tab product during blanking.

[0020] In an embodiment of the present invention, the two side positioning mechanisms are the same mechanism, both including a positioning cylinder and a positioning plate installed at the output end of the positioning cylinder. The two positioning plates are used to clamp the tab product and position the two side ends of the tab product.

[0021] In an embodiment of the present invention, the positioning plate is provided in an L shape.

[0022] In an embodiment of the present invention, the positioning plate is made of a high-temperature resistant insulating material.

[0023] In an embodiment of the present invention, at both side ends of the induction heating coil corresponding to the side positioning mechanism, inverted U-shaped notches are bent. The induction heating coil can pass through the output end of the positioning cylinder in a descending manner through the inverted U-shaped notches on both sides, forming a surrounding heating structure for the tab product.

[0024] In an embodiment of the present invention, the lifting module includes:

[0025] A plurality of guide posts installed at the upper end of the workbench;

[0026] A top plate installed at the upper end of the guide posts, and a lifting cylinder is installed on the top plate;

[0027] A support plate sleeving a plurality of guide posts at the same time. The output end of the lifting cylinder is connected to the upper end of the support plate, and the induction heating coil is installed at the lower end of the support plate;

[0028] A high-frequency power supply and a controller assembly are further provided at the upper end of the support plate. The induction heating coil is electrically connected to the high-frequency power supply and the controller assembly.

[0029] In an embodiment of the present invention, lifting limit mechanisms are provided on both sides of the support plate. The lifting limit mechanism includes an adjusting cylinder and a limit plate connected to the output end of the adjusting cylinder. The height of the limit plate is adjusted by the adjusting cylinder to limit the descending height of the lifting module.

[0030] In an embodiment of the present invention, the conveyor belt is coated with a high-temperature resistant protective coating, and the high-temperature resistant protective coating is any one of a polytetrafluoroethylene coating, a silicone coating, and a ceramic coating.

[0031] As described above, the automatic positioning induction heating device for tab production of the present invention has the following beneficial effects:

[0032] 1. By arranging a material ejecting mechanism and two side positioning mechanisms at the heating station, the material ejecting mechanism can lift the tab being transported on the transmission mechanism through the material ejecting plate and position its front end through the baffle. The two side positioning mechanisms can position the two side ends of the tab after it is lifted. The three-end positioning can ensure that each tab is in the same position and posture during the heating process, thus ensuring the stability of product production quality. When the two side positioning mechanisms position the two side ends of the tab, they can also make it in a suspended state, greatly reducing the shadow area during tab heating, which is beneficial to improving the heating effect and heating efficiency of the tab.

[0033] 2. By bending an inverted U-shaped notch on the induction heating coil, the design of the inverted U-shaped notch can reserve space for the output end of the positioning cylinder when the lifting module drives the induction heating coil to descend, enabling the induction heating coil to surround the tab in a circular manner, improving the heating uniformity of the tab and further enhancing the heating effect and heating efficiency of the tab.

[0034] 3. By coating a high-temperature resistant protective coating on the conveyor belt, the tab in a high-temperature state after heating can be directly placed on the conveyor belt for continuous transmission without more cooling time, improving the production efficiency of the tab.

[0035] 4. By arranging a lifting limit mechanism in the lifting module, the descending height of the lifting module can be adjusted, and then the descending position of the induction heating coil can be controlled to ensure the relative position between the induction heating coil and the tab.

[0036] 5. The automatic positioning induction heating device for tab production provided by the present invention uses a non-contact induction heating method to heat the tab. The induction heating directly generates eddy currents inside the metal through the principle of electromagnetic induction, making the tab itself heat up. It can reach the target temperature in a few seconds or even shorter time. Compared with the traditional conduction heating method, the heating speed is faster and the production efficiency is higher. When heating, the material ejecting mechanism cooperates with the two side positioning mechanisms to achieve precise positioning of the tab product, ensuring the accuracy of the heating area and the consistency of batch product production, and having excellent market application prospects.

[0047] Embodiment 1, please refer to Figures 1 - 4, this embodiment provides an automatic positioning induction heating device for tab production, including a workbench 1. There are two parallel transmission mechanisms 2 on the workbench 1. The two transmission mechanisms 2 are the same mechanisms, each including a stepping motor 21, a driving pulley 22 connected to the output end of the stepping motor 21, several driven pulleys 23, and a conveyor belt 24 sleeved on the driving pulley 22 and several driven pulleys 23 at the same time. A high-temperature resistant protective coating is applied on the conveyor belt 24. The tab products 3 are placed on both transmission mechanisms 2 at the same time, specifically on the upper end of the conveyor belt 24. The stepping motor 21 drives the driving pulley 22 to rotate, and the conveyor belt 24 rotates with the cooperation of several driven pulleys 23 to convey and feed the tab products 3. Along the transmission direction of the transmission mechanism 2 on the workbench 1, there are successively a heating station 11, a detection station 12, a kicking station 13, and a blanking station 14. The multi-station setting can realize the heating and detection functions of the tab products 3 on the same device.

[0048] Please refer to Figure 5 , on the heating station 11, there is a material pushing mechanism 4 and two side positioning mechanisms 5. The material pushing mechanism 4 is installed at the lower end of the workbench 1 and between the two transmission mechanisms 2. The two side positioning mechanisms 5 are installed on the opposite sides at the upper end of the workbench 1. Specifically, the material pushing mechanism 4 includes a material pushing cylinder 41 and a material pushing plate 42 installed at the output end of the material pushing cylinder 41. When the tab product 3 is transported to the heating station 11, the material pushing cylinder 41 drives the material pushing plate 42 to lift up and push the material. There is a baffle 421 at the front end of the material pushing plate 42, which is used to position the front end of the tab product 3 during material pushing. The two side positioning mechanisms 5 are the same mechanisms, each including a positioning cylinder 51 and a positioning plate 52 installed at the output end of the positioning cylinder 51. The positioning plate 52 is made of high-temperature resistant insulating material. The two positioning plates 52 are used to clamp the tab product 3 and position the two side ends of the tab product 3. The material pushing mechanism 4 cooperates with the two side positioning mechanisms 5 to perform three-end positioning on the tab product 3 to ensure that each tab is in the same position and posture during heating, thereby ensuring the stability of product production quality. After positioning, the material pushing mechanism 4 retracts, and the two side positioning mechanisms can position the two side ends of the tab and at the same time make it in a suspended state, greatly reducing the shadow area during tab heating, which is beneficial to improving the heating effect and heating efficiency of the tab. The positioning plate 52 is set in an L shape. The L-shaped positioning plate 52 can form a support while positioning and clamping the tab product 3, and can ensure the reliability of clamping the tab product 3 after the material pushing mechanism 4 retracts.

[0049] Please refer to Figure 6, a lifting module 6 is further provided on the heating station 11. The lifting module 6 is installed at the upper end of the workbench 1, and an induction heating coil 7 is installed at the lifting end of the lifting module 6. Specifically, the lifting module 6 includes a plurality of guide posts 61, and the guide posts 61 are installed at the upper end of the workbench 1; a top plate 62 installed at the upper end of the guide posts 61, and a lifting cylinder 63 is installed on the top plate 62; a support plate 64 sleeved with a plurality of guide posts 61 at the same time, and the output end of the lifting cylinder 63 is connected to the upper end of the support plate 64; lifting limit mechanisms 19 are provided on both sides of the support plate 64. The lifting limit mechanism 19 includes an adjustment cylinder 191 and a limit plate 192 connected to the output end of the adjustment cylinder 191. The height of the limit plate 192 is adjusted by the adjustment cylinder 191 to limit the descending height of the lifting module 6, and then the descending position of the induction heating coil 7 is regulated to ensure the relative position between the induction heating coil 7 and the tab. Due to the compactness of the structural design, the positioning cylinder 51 is located below the lifting limit mechanism 19, and a partition 18 is provided outside the positioning cylinder 51. When the lifting module 6 descends, the limit plate 19 presses against the partition 18.

[0050] The induction heating coil 7 is installed at the lower end of the support plate 64; a high-frequency power supply and a controller assembly 17 are further provided at the upper end of the support plate 64. The induction heating coil 7 is electrically connected to the high-frequency power supply and the controller assembly 17, and is specifically powered by the high-frequency power supply and the heating on and off is controlled by the controller; inverted U-shaped notches 71 are bent at both side ends of the induction heating coil 7 corresponding to the side positioning mechanism 5. The design of the inverted U-shaped notches can reserve space for the output end of the positioning cylinder 51 when the lifting module drives the induction heating coil to descend. The induction heating coil 7 can descend through the output end of the positioning cylinder 51 through the inverted U-shaped notches 71 on both sides, forming a surrounding heating structure for the tab product 3, improving the uniformity of tab heating and further improving the heating effect and heating efficiency of the tab.

[0051] A vision inspection camera 8 is provided on the inspection station 12. The vision inspection camera 8 is installed above the workbench 1 through a gantry 9 and is used to inspect the processing state of the tab product 3, including inspecting whether there are oxidation, discoloration or deformation phenomena on the surface of the tab after heating, etc.

[0052] The kicking station 13 is provided with a kicking mechanism 10 and an NG bin 15. The kicking mechanism 10 includes a kicking cylinder 101 and a kicking plate 102 installed at the output end of the kicking cylinder 101. The kicking mechanism 10 is installed at the upper end of one side of the workbench 1, and the NG bin 15 is installed on the other side of the workbench 1. Specifically, first grooves 20 and second grooves 25 are formed on both upper ends of the workbench 1 at the kicking station 13. The kicking cylinder 101 is installed in the first groove 20, and the kicking plate 102 corresponds to the side end of the conveyor belt 24. The second groove 25 is provided with an inclined surface that slopes downward from the inside to the outside. The NG bin 15 corresponds to the lower end of the second groove 25. When the unqualified tab products detected by the vision inspection camera 8 are transmitted to the kicking station 13, the kicking cylinder 101 drives the kicking plate 102 to extend, kicking the unqualified tab products 3 into the second groove 21 and falling into the NG bin 15 along the inclined surface in the second groove 21.

[0053] The blanking station 14 is provided with an OK bin 16. The OK bin 16 is placed at the transmission end of the transmission mechanism 2. In an actual workshop, a manipulator is equipped at the transmission end of the transmission mechanism 2. This manipulator is a commonly used industrial device and will not be elaborated here. When the qualified tab products detected by the vision inspection camera 8 are transmitted to the blanking station 14, the manipulator grabs the products and places them into the OK bin 16.

[0054] Embodiment 2, based on Embodiment 1, the positioning plate 52 used in the side positioning mechanism 5 is bakelite. Bakelite, also known as phenolic resin, is a thermosetting plastic with high heat resistance and can maintain stable physical and chemical properties in a high-temperature environment. During the induction heating process of the tab, the bakelite clamping tool can withstand high temperatures without deformation or damage, ensuring the stability and reliability of clamping. In addition, bakelite also has advantages such as good insulation, high mechanical strength, chemical corrosion resistance, low thermal conductivity, light weight, good wear resistance, low cost, strong environmental protection, and strong adaptability. These characteristics make bakelite an ideal material for the clamping tool during the tab heating process, which can effectively improve the heating efficiency, ensure operation safety, and extend the service life of the tool.

[0055] Embodiment 3, based on Embodiment 1, the high-temperature resistant protective coating applied on the conveyor belt 24 used in the transmission mechanism 2 is any one of polytetrafluoroethylene coating, silicone coating, and ceramic coating. The polytetrafluoroethylene PTFE coating has excellent high-temperature resistance and can withstand a high temperature of up to 300 °C in a short time. It can usually be continuously used in the range of 240 °C to 260 °C. Moreover, the polytetrafluoroethylene PTFE coating also has characteristics such as non-stickiness, wear resistance, and corrosion resistance, and is widely used in industries such as chemical industry, petroleum, pharmacy, and food processing. The silicone coating has excellent high-temperature resistance and can withstand a temperature of 1800 °C or even higher. This coating is commonly used in fields such as metallurgy, petroleum industry, natural gas extraction, and aerospace. The silicone coating shows good adhesion and strength at high temperatures and is not easy to crack. The ceramic coating has extremely high high-temperature resistance and can withstand extremely high temperatures. The ceramic coating performs excellently at high temperatures and has excellent corrosion resistance and mechanical properties. These coatings not only have excellent high-temperature resistance but also possess various other characteristics such as non-stickiness, wear resistance, and corrosion resistance. In the present invention, by applying a high-temperature resistant protective coating on the conveyor belt 24, the tab in a high-temperature state after heating can be directly placed on the conveyor belt for continuous transmission without more cooling time, improving the production efficiency of the tab.

[0056] In summary, the automatic positioning induction heating device for tab production provided by the present invention uses a non-contact induction heating method to heat the tab. Induction heating directly generates eddy currents inside the metal through the principle of electromagnetic induction, causing the tab itself to heat up. It can reach the target temperature in a few seconds or even shorter time. Compared with the traditional conduction heating method, the heating speed is faster and the production efficiency is higher. When heating, the blanking mechanism 4 cooperates with the two side positioning mechanisms 5 to achieve precise positioning of the tab product, ensuring the accuracy of the heating area and the consistency of batch product production, and having excellent market application prospects. Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0057] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
