Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a battery top cover encoder feeding device. Background Technology

[0002] In the field of new energy battery manufacturing, the battery top cover, as a key component for battery sealing and electrode connection, directly affects the safety and performance of the battery due to its production efficiency and assembly precision. On automated production lines, battery top covers are typically stored and transported in batches using encoders, and then picked up and transferred to subsequent assembly stations by robotic arms.

[0003] However, due to the simple design of traditional encoder disks, when battery top covers are elongated or stacked in multiple layers, problems such as top covers sticking together and positional misalignment can easily occur, making it difficult for robotic arms to grasp them accurately, thus affecting loading efficiency and yield. On the other hand, existing separation technologies mostly rely on a single vibratory feeder or air blowing device. When there is oil or dust contamination on the top cover surface, or when there are differences in materials (such as thin aluminum sheets versus hard stainless steel top covers), the separation effect decreases, making it difficult to meet diverse production needs. Therefore, it is necessary to design a battery top cover encoder disk loading device.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a battery top cover encoder feeding device to solve the problems that traditional encoders have simple structures, are prone to sticking and shifting when handling long or multi-layer stacked battery top covers, and that existing separation technologies are weak in dealing with complex working conditions and cannot meet production needs.

[0006] The technical solution adopted by this application to solve its technical problem is: a battery top cover encoder feeding device. It includes an encoder assembly, a separator assembly, and a feeding assembly. The encoder assembly includes a support frame, and the top of the support frame is connected to the encoder body via a first motor. Multiple sets of through-hole slots are evenly formed on the encoder body along its radial direction. The separator assembly includes multiple storage sections installed on the encoder body, with each storage section corresponding to a through-hole slot. Each storage section includes two sets of oppositely arranged concave separators, each set of separators having multiple placement sections for supporting the battery top cover. A cleaning section is bolted to both sets of separators. The cleaning section consists of two sets of symmetrically arranged slotted plates and two sets of guide plates. The guide plates are hollow and open on one side. The two sets of guide plates are perpendicularly connected to both ends of the slotted plates, forming a rectangular frame structure. The two sets of slotted plates are respectively attached to the two sets of separators. The cleaning section is adapted to move linearly along the guide plates to wipe and clean the bottom surface of the top cover.

[0007] Furthermore, a second motor is installed on the outer side of one set of the slot plates, and its output end is coaxially connected to a lead screw via a coupling. A second motor is fixedly installed on the side of one set of the slot plates, and a lead screw is fixedly installed on the output end of the second motor. The lead screw horizontally passes through the interior of the corresponding guide plate. A guide rod parallel to the lead screw is installed inside another set of guide plates. A sponge roller is provided between the lead screw and the guide rod, with movable blocks at both ends, and is adapted to the inner cross-sectional dimensions of the guide plate.

[0008] One set of the movable blocks is movably connected to the guide rod via a linear bearing, while the other set of movable blocks has a threaded sleeve that matches the lead screw, forming a lead screw and nut pair transmission structure.

[0009] Furthermore, the sponge roller is housed in the groove of the slot plate in the default state. The groove depth of the slot plate is slightly smaller than the outer diameter of the sponge roller, so that it is slightly squeezed to keep it dry. The overall size of the cleaning section is larger than the area enclosed by the two sets of partitions, ensuring that it does not interfere with the feeding assembly's gripping action on the battery top cover on the support block.

[0010] Furthermore, the placement part is integrated inside the partition frame and includes a movable shaft mounted by bearings. Two sets of support blocks are mounted on the movable shaft by sleeve and fixed by bolts. There is a certain distance between the two sets of support blocks to accommodate battery top covers of different widths.

[0011] The placement part also includes a fixed shaft installed on the partition frame, which is positioned higher than and parallel to the movable shaft, and is used to limit the rotation range of the support block. The support block is designed as a stepped structure, divided into a support end and a limiting end. The support end has a larger volume and the outer end surface is horizontal, which is used to support the top cover of the battery. Its size is precisely matched with the bottom of the top cover.

[0012] The upper surface of the limiting end contacts the outer surface of the fixed shaft. The gravity of the supporting end keeps the support block in a horizontal position by default, ensuring the stable placement of the top cover. At the same time, the limiting effect of the fixed shaft prevents the support block from rotating excessively and causing the top cover to slip. An auxiliary frame is also installed on the support frame at the lower end of the code disk body. A first cylinder is vertically fixed on the auxiliary frame, and a push plate is fixedly installed on the telescopic end of the first cylinder.

[0013] Furthermore, the feeding assembly includes a base disposed on one side of the support frame, a bracket fixedly mounted on the base, and a horizontally arranged linear module fixedly mounted at one end of the bracket. The linear module mainly consists of a slide rail, a slider, a lead screw, a nut seat, a movable end, and a drive motor. A second cylinder is fixedly mounted on the movable end, and its output end extends vertically downward and is connected to a rotary motor. The output shaft of the rotary motor is connected to a pneumatic gripper. The pneumatic gripper and the first cylinder are linked and adapted through a control system.

[0014] Furthermore, a conveying component is provided on one side of the feeding component. The conveying component includes a conveyor belt disposed on one side of the base. The conveyor belt has two sets of support legs for supporting it. Baffles are fixedly installed on both sides of the conveyor belt. There is a gap between the two sets of baffles. The gap width is adapted to the outer dimensions of the battery top cover to form a guide channel.

[0015] Furthermore, specific spacing is reserved between multiple storage units to ensure that the battery top covers in adjacent storage units are placed separately.

[0016] The beneficial effects of this application are as follows: The battery top cover encoder feeding device provided by this application, through the through-hole groove of the encoder assembly and the storage part of the separator assembly, and in conjunction with the specific spacing between the separators, avoids the top covers sticking together when multiple layers are stacked; the support block of the placement part adopts a gravity self-balancing structure, and through the cooperation of the movable shaft and the fixed shaft, the top cover automatically yields and provides stable support during the lifting process. The cleaning part is integrated into the separator, and the sponge roller moves linearly along the guide plate under the drive of the screw, actively wiping and cleaning the bottom surface of the gripped top cover, effectively removing dust and oil stains, breaking through the limitations of traditional air blowing cleaning, and adapting to the surface treatment needs of top covers of various materials.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1 to 3 As shown, this application provides a battery top cover encoder feeding device, including encoder assembly 1, separator assembly 2, feeding assembly 3 and conveying assembly 4.

[0028] The basic support structure of the code disk assembly 1 is a support frame 11, which is integrally formed from high-strength aluminum alloy. A first motor 12, a high-precision servo motor, is fixedly mounted on the top of the support frame 11 using bolts. The output of the first motor 12 is connected to the code disk body 13 via a precision coupling to ensure stable power transmission. The code disk body 13 has a disc-shaped structure and is made of wear-resistant engineering plastic, with its surface hardened to improve durability. Multiple sets of through-hole slots 131 are evenly distributed along the radial direction of the code disk body 13 at equal angles to the center of the code disk.

[0029] The separating component 2 includes multiple storage sections mounted on the code disk body 13. These storage sections are evenly arranged radially along the code disk body 13 and correspond to the through-hole slots 131. Each storage section includes two sets of oppositely arranged concave separating frames 21. Multiple placement sections are mounted on each of the two sets of separating frames 21. Each placement section is integrated inside the separating frame 21 and includes a movable shaft 22 mounted by bearings. Two sets of support blocks 24 are mounted on the movable shaft 22 by sleeve and fixed by bolts. There is a certain distance between the two sets of support blocks 24, so as to adapt to battery top covers of different widths and meet the compatibility requirements of various specifications such as square and strip.

[0030] A specific distance is reserved between multiple storage sections to ensure that the battery top covers in adjacent storage sections are placed separately and to avoid adhesion due to contact. The placement section also includes a fixed shaft 23 fixedly installed on the separator 21. Its position is higher than the movable shaft 22 and parallel to the movable shaft 22. It is used to limit the rotation range of the support block 24. The support block 24 is designed with a stepped structure, divided into a support end and a limiting end: the support end is larger in volume and the outer surface is a horizontal plane, which is used to support the battery top cover. Its size is precisely adapted to the bottom of the top cover; the upper surface of the limiting end contacts the outer surface of the fixed shaft 23. Using the gravity of the support end, the support block 24 is kept in a horizontal position by default. This ensures that the top cover is placed stably, while the limiting effect of the fixed shaft 23 prevents the support block 24 from rotating excessively and causing the top cover to slip off.

[0031] An auxiliary frame 25 is fixedly installed on the support frame 11 at the lower end of the encoder body 13. A first cylinder 26 is vertically fixedly installed on the auxiliary frame 25. A push plate (not shown in the figure) is fixedly installed on the telescopic end of the first cylinder 26. The push plate is made of smooth stainless steel with rounded edges to avoid damaging the battery top cover during pushing. The push plate and the telescopic end of the cylinder are fixed by a detachable connector for easy maintenance and replacement later.

[0032] During operation, the first cylinder 26 drives the push plate to move vertically upwards. The push plate passes through the through-hole groove 131 on the encoder body 13 and contacts the lower surface of the bottom battery cover. As the push plate continues to rise, the battery cover is smoothly lifted and moves upwards. At this time, the push plate contacts the bottom surface of the cover placed on the next higher level, and the upper edge of the cover gradually contacts the lower surface of the support end of the support block 24. Since the movable shaft 22 of the support block 24 can rotate freely, under the pushing force of the cover, the support block 24 rotates slightly around the movable shaft 22, the limiting end lifts up and disengages from the contact with the fixed shaft 23, causing the support end to open outwards, forming enough space for the cover to pass through smoothly.

[0033] Once the top cover has completely passed the support end, the support block 24 automatically falls back to a horizontal position due to the gravity of the support end. At this time, the fixed shaft 23 again restricts the rotation of the support block 24, allowing the support end to stably support the edge of the battery top cover, completing the transfer of the top cover to the next placement section. Subsequently, the first cylinder 26 drives the push plate to reset downwards, preparing for the next pushing action. Throughout the process, by precisely controlling the stroke and timing of the cylinders, the stability and reliability of each pushing action are ensured, achieving orderly feeding of the battery top cover and effectively improving the overall feeding efficiency.

[0034] Cleaning parts are fixedly fitted onto the two sets of partition frames 21 by bolts. The cleaning parts consist of two sets of symmetrically arranged groove plates 27 and two sets of guide plates 28. The guide plates 28 are hollow structures with an opening on one side. The two sets of guide plates 28 are perpendicularly connected to the two ends of the groove plates 27 to form a rectangular frame structure. The two sets of groove plates 27 are respectively attached to the two sets of partition frames 21.

[0035] A second motor 29 is fixedly installed on the outer side of one set of slot plates 27, and its output end is coaxially connected to a lead screw 210 through a coupling. A second motor 29 is fixedly installed on the side of one set of slot plates 27, and a lead screw 210 is fixedly installed on the output end of the second motor 29. The lead screw 210 horizontally passes through the interior of the corresponding guide plate 28. A guide rod 213 parallel to the lead screw 210 is fixedly installed inside another set of guide plates 28.

[0036] A sponge roller 212 is provided between the lead screw 210 and the guide rod 213. The roller has movable blocks 211 at both ends and is adapted to the inner cross-sectional dimensions of the guide plate 28 to ensure that the movable blocks 211 can slide linearly along the inner wall of the guide plate 28. One set of movable blocks 211 is movably connected to the guide rod 213 through a linear bearing, and the other set of movable blocks 211 has a threaded sleeve that matches the lead screw 210, forming a lead screw and nut pair transmission structure.

[0037] In its default state, the sponge roller 212 is housed within the groove of the slot plate 27. The groove depth of the slot plate 27 is slightly smaller than the outer diameter of the sponge roller 212, subjecting it to slight compression to maintain its dryness. The overall size of the cleaning section is larger than the area enclosed by the two sets of separators 21, ensuring that it does not interfere with the feeding assembly 3's gripping action on the battery top cover of the support block 24. When the top cover is gripped and rests on the upper end of the separator 21, the second motor 29 is activated to drive the lead screw 210 to rotate, causing the sponge roller 212 to move linearly along the guide plate 28, ensuring that its surface makes full contact with the bottom surface of the battery top cover, thereby wiping and cleaning the bottom surface of the top cover and effectively removing adsorbed dust or oil.

[0038] The storage, positioning, and cleaning of battery top covers are achieved through mechanical transmission and structural innovation. During operation, the first motor 12 drives the encoder body 13 to rotate, aligning the target storage section with the loading station. At this time, the first cylinder 26 drives the push plate to rise, passing through the through-hole slot 131 and lifting the bottommost battery top cover. During the lifting process, the top cover pushes the support end of the upper-level support block 24 outward (the movable shaft 22 rotates). After the top cover completely passes the support end, the support block 24 falls back due to gravity and supports the edge of the top cover, completing the layer transfer. This design utilizes a gravity self-balancing structure to ensure that the support block 24 maintains a horizontal posture by default, while the fixed shaft 23 restricts its excessive rotation to prevent the top cover from slipping, achieving the orderly upward movement of the battery top cover.

[0039] When the battery top cover is picked up by the feeding assembly 3 and held above the separator 21, the cleaning unit starts working. The second motor 29 drives the lead screw 210 to rotate, causing the sponge roller 212 to move linearly along the guide plate 28, so that it extends out of the slot plate 27 and contacts the bottom surface of the top cover, removing surface impurities through squeezing and friction. After cleaning, the sponge roller 212 retracts into the slot plate 27 to reset. Throughout the process, the external dimensions of the cleaning unit are designed to ensure that it does not interfere with the feeding action, while the cooperation between the lead screw nut pair and the linear bearing ensures the stability of the cleaning action, ultimately achieving the cleaning and reliable feeding of the battery top cover.

[0040] In some embodiments, such as Figures 2-3 As shown, the feeding assembly 3 includes a base 31 disposed on one side of the support frame 11. A bracket 32 ​​is fixedly installed on the base 31. A horizontally arranged linear module 33 is fixedly installed at one end of the bracket 32. The linear module 33 mainly consists of a slide rail, a slider, a lead screw, a nut seat, and a drive motor. The parallel slide rails on both sides provide a guiding path for the module. The slider is precisely matched with the slide rail to ensure smooth sliding of the movable end. The lead screw in the middle runs through the entire length of the module and is fixed by bearing seats at both ends. The nut seat is threadedly connected to the lead screw and rigidly connected to the movable end. The drive motor is coaxially connected to the lead screw through a coupling. When working, the motor drives the lead screw to rotate, and the nut seat drives the movable end to make linear reciprocating motion along the slide rail, realizing precise horizontal displacement control.

[0041] A second cylinder 34 is fixedly mounted on the movable end, with its output end extending vertically downward and connected to a rotary motor. The output shaft of the rotary motor is connected to a pneumatic gripper 36, allowing the pneumatic gripper 36 to rotate 90° with the drive of the rotary motor to adapt to gripping needs in different directions. During operation, the linear module 33 drives the movable end to translate, precisely positioning the pneumatic gripper 36 directly above the target storage section. At this time, the second cylinder 34 is activated, driving the pneumatic gripper 36 to descend to the position where it contacts the top cover of the uppermost battery, and the gripper closes to complete the gripping action.

[0042] The pneumatic gripper 36 and the first cylinder 26 are linked and adapted through a control system. When the pneumatic gripper 36 removes the battery top cover from the uppermost support block 24, the control system simultaneously triggers the first cylinder 26 to move, causing the push plate to rise and pass through the through-hole slot 131, pushing the lowermost battery top cover upwards. During the lifting process, the battery top cover passes through the support ends of each level of support block 24 in sequence, and smoothly passes through the previous level placement part using the rotatable structure of the support block 24, until a new battery top cover is pushed onto the uppermost support block 24, completing the automatic feeding process and ensuring continuous and stable operation of the equipment.

[0043] In other embodiments, such as Figures 2-3 As shown, the conveying assembly 4 includes a conveyor belt 41 disposed on one side of the base 31. The conveyor belt 41 has two sets of support legs 44 for supporting it. Baffles 42 are fixedly installed on both sides of the conveyor belt 41, with a gap between the two sets of baffles 42. The width of this gap is adapted to the outer dimensions of the battery top cover, forming a guide channel. When the pneumatic gripper 36 places the battery top cover onto the conveyor belt 41, the baffles 42 can restrict the conveying path of the battery top cover, preventing it from shifting or tipping over during conveying, ensuring that the battery top cover is accurately conveyed to the next process along a predetermined trajectory.

[0044] Working principle: First, the first motor 12 in the encoder assembly 1 drives the encoder body 13 to rotate, accurately positioning the corresponding storage section to the loading station. The radially distributed through-hole slots 131 correspond to the structure of the separator assembly 2. Subsequently, the first cylinder 26 in the separator assembly 2 drives the push plate to pass through the through-hole slots 131, lifting the bottom battery top cover. Utilizing the linkage structure between the movable shaft 22 and the support block 24, the top cover pushes open the support end of the upper-level support block 24 layer by layer. The fixed shaft 23 restricts the rotation range of the support block 24, ensuring stable transfer of the top cover at each level.

[0045] The linear module 33 of the feeding assembly 3 drives the pneumatic gripper 36 to move horizontally to the target storage section. The second cylinder 34 drives the gripper to descend and grab the top cover. After grabbing, the cleaning section on the separator 21 is activated. The second motor 29 drives the sponge roller 212 to slide along the guide plate 28 through the lead screw 210 to complete the cleaning of the bottom surface of the top cover. Finally, the conveyor belt 41 of the conveying assembly 4, guided by the baffle 42, stably conveys the cleaned top cover to the next process. At the same time, the pneumatic gripper 36 is linked with the first cylinder 26. After the gripper takes away the top cover, the first cylinder 26 immediately pushes a new top cover to fill the gap, forming a continuous cycle operation.

[0046] To address the issues of top cover sticking and shifting that are common in traditional encoder structures, this device avoids top cover contact and sticking through the spacing design between storage sections. The gravity self-balancing structure of the support block 24 (with the support end and the limiting end working together) combined with the limiting function of the fixed shaft 23 ensures accurate top cover positioning. In terms of separation technology, the first cylinder 26 pushes the push plate to achieve forced separation, and the pneumatic gripper 36 precisely grasps the top cover, which is compatible with top covers made of different materials such as long strips, aluminum sheets, and stainless steel. The cleaning section integrated into the separator 21 actively removes oil and dust through the combination of the lead screw 210 and the sponge roller 212, overcoming the defect of traditional separation technology being sensitive to contamination.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
