Description

Technical Field

[0001] This invention belongs to the field of drilling equipment technology, and more specifically, relates to a drilling equipment for the production of lithium battery components. Background Technology

[0002] During the drilling and machining process of lithium battery components, high-temperature wear and other defects are prone to occur due to continuous high-speed cutting of the drill bit. In order to stabilize the machining quality and extend the service life of the drill bit, reliable lubrication and maintenance operations must be carried out on the drill bit to meet the mass production control requirements of precision drilling for lithium battery components.

[0003] However, most traditional drilling equipment does not have an integrated self-lubrication function. It can only rely on manual periodic application of lubricating medium or point-to-point lubrication through external oil pipes. When the drill bit needs maintenance after completing a batch of drilling operations, the machine needs to be stopped and the drill bit removed from the equipment to be lubricated separately. This leads to frequent production line interruptions, reduced processing continuity, and decreased overall production efficiency. Moreover, external oil pipes can only achieve local single-point oil supply, resulting in uneven lubrication around the drill bit. The cutting parts do not receive sufficient lubrication, and problems such as excessive drill bit temperature rise and accelerated wear still occur. It is difficult to ensure the long-term stable accuracy of drilling of parts. Summary of the Invention

[0010] According to a preferred embodiment, mounting plates are provided on both sides of the processing panel and the support platform.

A second lifting mechanism is provided on both sides of the support platform, and the mounting plates located on both sides of the support platform are installed on the second lifting mechanism.

[0011] According to a preferred embodiment, the adsorption platform includes an adsorption shell and an adsorption panel. The adsorption shell is mounted on the lifting mechanism, and the adsorption panel covers the top of the adsorption shell. The adsorption panel is provided with multiple adsorption zones, and multiple adsorption through holes are formed in the adsorption zones. An adsorption box is provided at the bottom of the adsorption panel corresponding to the adsorption area. The adsorption box is connected to the adsorption panel to form an adsorption cavity. The adsorption cavity is in communication with the adsorption through hole. The adsorption box is connected to a negative pressure fan, and a negative pressure environment is formed inside the adsorption cavity.

[0012] According to a preferred embodiment, multiple sets of protective plates are provided above the adsorption box. Each protective plate has a ventilation area corresponding to the adsorption area. Sealing ribs are provided within the ventilation area of ​​each protective plate, and these ribs contact the top surface of the protective plate, forming a ventilation cavity. The ventilation cavity communicates with the adsorption cavity through adsorption through-holes. Multiple sets of ventilation holes are opened in the ventilation area of ​​each protective plate, allowing the ventilation cavity to communicate with the outside environment. The multiple sets of protective plates form an adsorption platform, on which lithium battery components are placed.

[0013] According to a preferred embodiment, the protective plate is divided into multiple sets of cooling chambers by the sealing ribs, and the multiple sets of cooling chambers and the multiple sets of ventilation chambers are arranged at intervals; Two sets of partitions are symmetrically arranged inside one set of sealing ribs on the protective plate. The two sets of partitions separate the ventilation cavity inside the sealing rib into two sets of flow guiding cavities. Multiple sets of flow guiding grooves are opened on both sides of the sealing rib.

The movable sleeve is equipped with a piston to form a piston structure, and the piston is connected to the bottom of the lifting rod via a connecting rope on the side facing the lifting sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This device integrates a lubrication assembly within the drilling housing, enabling in-situ online lubrication of the drill bit without the need to disassemble the drill bit or use an external oil pipe for single-point oil supply. After the first lifting mechanism retracts the drilling section to the lubrication position, the lubrication seat slides into place, and the first and second lubrication components simultaneously adhere to the outer wall of the drill bit and the spiral groove. The lubricating fluid is diverted through the guide cavity and delivered to the two lubrication components, completely covering the cutting area of ​​the drill bit. This structure eliminates the need to stop the machine to disassemble and reassemble the drill bit for lubrication maintenance, ensuring continuous processing on the production line and improving mass production efficiency. At the same time, the uniform and sufficient lubrication around the drill bit effectively suppresses cutting temperature rise, reduces drill bit wear, extends service life, and continuously stabilizes the drilling accuracy of lithium battery components, meeting the requirements of large-scale precision mass production.

[0016] 2. The processing platform can switch between clamping and adsorption modes. The two clamping modes are respectively adapted to the rigid clamping of conventional hard lithium battery workpieces and the negative pressure adsorption of thin sheets and thin-walled easily deformable lithium battery components, realizing adaptive clamping of workpieces of different specifications and materials, and making the equipment more versatile. In the clamping mode, the clamping cylinder drives the clamping parts and the flexible structure with fixed airbags to laterally limit the workpiece. At the same time, the second lifting mechanism can avoid the clamping structure as a whole, which facilitates the loading and unloading of workpieces and does not interfere with the operation of the adsorption table.

[0017] 3. The adsorption table integrates a linkage lifting structure. The negative pressure in the adsorption chamber synchronously drives the piston to pull the lifting rod back, ensuring the workpiece is fully attached to the adsorption platform for reliable adsorption processing. After processing is completed and the negative pressure is removed, the spring automatically lifts the lifting rod to push the workpiece away from the protective plate, eliminating the material handling resistance caused by the workpiece adsorption and attachment. This facilitates the automated mechanism to grab and unload the workpiece. The entire process of loading, clamping, processing, and unloading is smooth and seamless, further enhancing the automation level and continuous processing capability of the entire drilling production line.

Detailed Implementation

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1 to 12 As shown, the present invention provides a drilling device for the production of lithium battery components, including a drilling mechanism and a processing platform for supporting and adaptively clamping different types of lithium battery components. The drilling mechanism is arranged above the processing platform and can perform lifting and feeding drilling operations relative to the processing platform. It works in conjunction with the processing platform below to clamp and fix the lithium battery components, thereby completing the drilling processing steps for various types of lithium battery hard shells and soft electrode sheet components.

[0023] The drilling mechanism includes a drilling housing 11 and a drilling section. The drilling housing 11 serves as the external load-bearing and protective base for the entire drilling mechanism, providing installation space and a protective barrier for various internal functional structures, preventing external dust and processing debris from entering the structure and causing component jamming and wear. The drilling housing 11 is fixedly connected to an external drive arm, which can drive the entire drilling mechanism to complete lateral and longitudinal position adjustments to adapt to the drilling position processing requirements of different sized parts. The drilling housing 11 is equipped with a first lifting mechanism, which provides vertical lifting power and stroke support for the drilling section, and controls the extension and retraction of the drilling section. The drilling section is assembled in the internal space of the drilling housing 11 and is fixedly installed at the power output end of the first lifting mechanism. Relying on the extension and retraction movement of the first lifting mechanism, the drilling section can complete the lifting and retraction switching inside the drilling housing 11, corresponding to the extended working state and the retracted lubrication state, realizing the automatic switching between drilling operation and drill bit 32 maintenance conditions.

[0024] The drilling housing 11 is also equipped with a lubrication assembly. The lubrication assembly is arranged laterally in the drilling section and will not interfere with the normal drilling feed action of the drilling section. It can be used for all-round lubrication and maintenance after the drilling section is stored. The lubrication assembly includes a lubrication seat 21, a first lubricating element 22 and a second lubricating element 23. The lubrication seat 21 is the core bearing base of the lubrication assembly. The lubrication seat 21 and the drilling housing 11 are connected by a sliding connection, which allows the lubrication seat 21 to slide horizontally inside the drilling housing 11 to adapt to the position changes of the drilling section and ensure that the lubrication structure can fit the drilling section to complete the docking operation.

[0025] The surface of the lubrication seat 21 is divided into a first lubrication zone and a second lubrication zone, which are used to assemble and fix different lubrication functional components to achieve zoned lubrication operations. The first lubricating component 22 is fixedly assembled in the internal position of the first lubrication zone, and its positioning is completed by relying on the first lubrication zone, which restricts the working position of the first lubricating component 22, prevents displacement during lubrication operations, and ensures the stability of the working position. The lubrication seat 21 has a guide cavity inside, which is used to introduce and guide lubricating fluid, and can smoothly deliver externally supplied lubricating fluid to each lubrication structure position. The lubrication seat 21 also has a drain hole inside, one end of which is interconnected with the guide cavity, and the other end of which extends and connects to the position of the first lubricating component 22, so that the lubricating fluid inside the guide cavity can be continuously delivered to the surface of the first lubricating component 22 through the drain hole, providing a medium supply for the lubrication operation of the first lubricating component 22.

[0026] The second lubricating element 23 is assembled inside the second lubrication zone. A rotatable connection structure is used between the second lubricating element 23 and the lubrication seat 21, allowing the second lubricating element 23 to rotate angularly and finely adjust its position within the second lubrication zone to adapt to the structure of the drilling section. The second lubricating element 23 communicates with the guide cavity inside the lubrication seat 21 via an external conduit. Lubricating fluid diverted from the guide cavity can be delivered to the position of the second lubricating element 23 through the conduit, ensuring a continuous supply of lubricating medium. When the equipment switches to lubrication mode, the drilling section retracts into the drilling housing 11. By sliding and adjusting the position of the lubrication seat 21, the first lubricating element 22 and the second lubricating element 23 can simultaneously contact the surface of the drilling section, providing synchronous lubrication from different positions and reducing wear and high temperatures caused by high-speed cutting.

[0027] Both the first lubricating element 22 and the second lubricating element 23 are made of porous absorbent sponge material, possessing excellent liquid permeability and storage capabilities. When lubricating fluid is injected into the guide cavity, the lubricating fluid in the guide cavity will continuously permeate into the entire interior of the first lubricating element 22 through the leakage holes, ensuring that the first lubricating element 22 uniformly absorbs the lubricating fluid and that the contact area between the first lubricating element 22 and the drilled part is covered with lubricating medium. At the same time, the second lubricating element 23 has a guide cavity inside, and the lubricating fluid in the guide cavity is introduced into the cavity of the second lubricating element 23 through the conduit, and then evenly permeates into the entire structure of the second lubricating element 23 through the microporous structure of the cavity, ensuring that the second lubricating element 23 is completely wetted with lubricating fluid, ensuring that the contact area between the second lubricating element 23 and the drilled part can continuously carry out the lubricating medium, and stably complete the bonding and lubrication operation.

[0028] The second lubricating element 23 also has a rigid portion, and the cavity is entirely formed inside the rigid portion of the second lubricating element 23. The rigid portion can support and shape the overall structure of the second lubricating element 23, maintaining its overall shape and installation accuracy, and preventing deformation of the second lubricating element 23 during angle adjustment and contact with the drilled part. At the same time, the rigid portion can support the cavity structure, keep the internal flow channels of the cavity unobstructed, prevent the cavity from deforming and becoming blocked under pressure, and ensure that the lubricating fluid can be stably introduced into the second lubricating element 23, continuously supplying the medium for lubrication operations.

[0029] like Figure 2 , Figure 5 , Figure 6 As shown, the drilling section includes a drive motor 31 and a drill bit 32. The drive motor 31 is fixedly mounted at the output end of the first lifting mechanism. The first lifting mechanism can drive the drive motor 31 to perform vertical lifting and lowering movements, thereby changing the extension and retraction position of the drill bit 32. The drill bit 32 is fixedly mounted on the output shaft end of the drive motor 31. When the drive motor 31 is running, it can drive the drill bit 32 to rotate continuously, providing rotational power for drilling and cutting operations of lithium battery components.

[0030] The surface of the first lubricating element 22 has a groove 33, the contour of which is adapted to the external cylindrical structure of the drill bit 32. During the process of switching the equipment to the lubrication state, the drill bit 32 moves upward with the drive motor 31 and is housed inside the drilling housing 11. At the same time, the lubrication seat 21 drives the first lubricating element 22 and the second lubricating element 23 to slide towards the drill bit 32, ultimately causing the drill bit 32 cylindrical body to be inserted into the groove 33, achieving a close contact between the first lubricating element 22 and the outer surface of the drill bit 32. Relying on the limiting structure of the groove 33, the contact range between the first lubricating element 22 and the drill bit 32 is increased, ensuring that the lubricating medium can be evenly adhered to the outer wall of the drill bit 32.

[0031] A rotary motor 34 is fixedly mounted on the outer side of the lubrication seat 21. The output shaft of the rotary motor 34 is fixedly connected to the second lubricating element 23. The rotation of the rotary motor 34 can cause the second lubricating element 23 to deflect at an angle, adjusting the tilting posture of the second lubricating element 23. The outer wall of the drill bit 32 is provided with a spiral groove 35 along its length. The spiral groove 35 is a conventional chip removal structure for the cutting operation of the drill bit 32. Before the lubrication operation is started, the rotary motor 34 drives the second lubricating element 23 to rotate and tilt, so that the tilting angle of the second lubricating element 23 is consistent with the tilting angle of the spiral groove 35, allowing the second lubricating element 23 to be inserted into the internal space of the spiral groove 35, so that the surface of the second lubricating element 23 forms a close contact with the inner wall of the spiral groove 35, and performs targeted lubrication operation on the area of ​​the spiral groove 35.

[0032] During the overall lubrication operation, the first lifting mechanism drives the drive motor 31 and the drill bit 32 to move upward slightly continuously. At the same time, the drive motor 31 drives the drill bit 32 to rotate at a low speed. The upward movement speed of the drill bit 32 is matched with the rotation speed, which can offset the positional deviation caused by the displacement of the components. This ensures that the first lubricating component 22, which is attached to the outer wall of the drill bit 32, and the second lubricating component 23, which is engaged inside the spiral groove 35, always maintain contact with the drill bit 32. During the rotation of the drill bit 32, uniform lubrication is completed throughout the entire area, improving the overall lubrication coverage of the drill bit 32.

[0033] The first lubricating element 22 and the second lubricating element 23 can effectively apply lubricating medium to the outer surface of the drill bit 32 and the inner wall of the spiral groove 35 simultaneously, fully covering the cutting working area of ​​the drill bit 32, alleviating the temperature rise and wear caused by high-speed cutting of the drill bit 32, reducing the aging wear of the drill bit 32 during long-term operation, and at the same time wetting and softening the fine dust and debris attached to the inside of the spiral groove 35, maintaining the cleanliness of the surface structure of the drill bit 32, and ensuring the operational stability of the drill bit 32 in subsequent drilling operations.

[0034] Two sets of first lubrication zones are provided, symmetrically arranged on the left and right sides of the second lubrication zone. This symmetrical arrangement allows lubrication points to be formed on both sides of the drill bit 32 simultaneously, balancing the stress state of the drill bit 32 during lubrication and preventing positional displacement caused by unilateral lubrication contact. Each set of first lubrication zones is equipped with a set of first lubricating components 22. The first lubricating components 22 on both sides can simultaneously adhere to the outer wall of the drill bit 32 from both sides, expanding the lubrication coverage area of ​​the outer column of the drill bit 32.

[0035] The lubrication seat 21 has independent guide chambers corresponding to the two sets of first lubrication zones. The two sets of guide chambers are interconnected by a connecting conduit. Either set of guide chambers is connected to an external lubricating fluid supply mechanism. The lubricating fluid output from the external lubricating fluid supply mechanism can first enter one set of guide chambers, and then be diverted to the other set of guide chambers through the connecting conduit, so as to achieve synchronous supply of lubricating fluid to the two sets of guide chambers, ensuring that the supply of lubricating medium to the first lubrication components 22 on both sides is consistent and maintaining the uniformity of lubrication operation on both sides.

[0036] The device's working state corresponds to the drilling operation condition. At this time, the first lifting mechanism drives the drilling part to move downward, so that the drill bit 32 extends and protrudes to the outside of the drilling shell 11 and is exposed above the processing platform, so that the lithium battery components placed on the processing platform can be directly drilled and cut.

[0037] The lubrication state of the device corresponds to the maintenance condition of the drill bit 32. At this time, the first lifting mechanism drives the drilling part to retract upward, so that the drive motor 31 and the drill bit 32 are completely stored and hidden in the internal space of the drilling shell 11. With the sliding contact action of the lubrication component, the all-round lubrication and maintenance operation of the drill bit 32 is completed.

[0038] like Figure 2 , Figure 4 , Figure 7 As shown, the processing platform includes a support platform 401, two sets of processing panels 402, and an adsorption platform. The support platform 401 serves as the basic load-bearing structure of the entire processing platform, capable of supporting all components above it, as well as clamping and lifting-related execution structures, providing an installation reference for each moving part. The two sets of processing panels 402 are arranged symmetrically, allowing for synchronous translational movements towards or away from each other, adapting to the switching requirements of different clamping modes. The sides of the processing panels 402 are equipped with movable pulleys 403. For each set of movable pulleys 403, a pulley rail 404 is fixedly installed on the side wall of the support platform 401. The movable pulleys 403 are embedded inside the pulley rails 404, which constrain the trajectory of the movable pulleys 403. The movable pulleys 403 can slide along the length of the pulley rails 404, thereby driving the entire processing panel 402 to move smoothly and reducing the sliding resistance generated during panel movement.

[0039] Inside the support platform 401, a lead screw slide is installed at the bottom of each processing panel 402. The lead screw slide can output linear reciprocating power. The bottom side of the processing panel 402 is connected to the motion execution end of the lead screw slide through a connecting rod. When the lead screw slide is running, the power is transmitted to the processing panel 402 through the connecting rod, driving the processing panel 402 to complete the translational movement. Relying on the self-locking characteristic of the lead screw slide, the panel can maintain its current position after moving to the designated position and will not shift on its own.

[0040] The adsorption platform is positioned in the middle area of ​​the two processing panels 402. A lifting mechanism is mounted on the support platform 401, and the adsorption platform is fixedly mounted on the power output end of the lifting mechanism. The lifting mechanism can drive the adsorption platform to move vertically up and down, changing the height of the adsorption platform. By relying on the horizontal translation of the processing panels 402 in conjunction with the lifting action of the adsorption platform, the entire processing platform can switch between two different working conditions: clamping mode and adsorption mode, adapting to the fixing and placement requirements of different types of lithium battery components.

[0041] In the clamping state, the lifting mechanism drives the adsorption table to move downward, so that the entire adsorption table is below the horizontal plane of the processing panel 402. The lead screw slide drives the two sets of processing panels 402 to move towards the center of the support platform 401. The two processing panels 402 are connected and spliced ​​together, and the spliced ​​plate surface forms a complete working bearing plane. The lithium battery components are directly placed on the surface of the spliced ​​working platform, and the bottom of the workpiece is supported by the spliced ​​plate surface. The workpiece can be fixed by the lateral limiting structure afterward.

[0042] In the adsorption state, the lead screw slide moves the two sets of processing panels 402 toward the two ends of the support platform 401 respectively. The two processing panels 402 are separated from each other, leaving a gap in the middle. The lifting mechanism pushes the adsorption platform upward, raising the adsorption platform to the gap in the middle of the two processing panels 402. The upper surface of the adsorption platform and the upper surface of the processing panel 402 are at the same height plane. The lithium battery components are laid flat on the platform of the adsorption platform. The workpiece is fixed by the negative pressure structure of the adsorption platform and will not be squeezed by the rigid clamping structure.

[0043] The lifting mechanism can adopt a linear lifting drive structure to achieve stable vertical lifting and adjustment of the adsorption table. A suitable lifting module can be selected according to actual assembly requirements and equipment installation space, meeting the switching needs of both low-position avoidance and high-position leveling of the adsorption table, ensuring smooth operation and controllable position during the lifting process. For example, the lifting mechanism can use an electric push rod lifting module, a screw lifting module, or a cylinder lifting module. All of these structures can achieve vertical linear reciprocating lifting motion, accurately matching the lifting stroke requirements of the adsorption table, adapting to the opening and closing rhythm of the processing panel 402, ensuring smooth switching between clamping and adsorption states, and adapting to the clamping and processing needs of lithium battery components of different specifications.

[0044] Mounting plates 405 are mounted on the sides of the processing panel 402 and both sides of the support platform 401. These mounting plates 405 serve as support bases, providing fixed mounting positions for subsequent clamping actuators. They integrate various clamping drive components on the sides of the processing area without interfering with workpiece loading / unloading or drilling feed. Each mounting plate 405 is fixedly mounted with a clamping cylinder 406, which outputs horizontal extension and retraction power. The piston rod end of the clamping cylinder 406 is fixedly connected to a clamping element 407. When the equipment is in the clamping state, each set of clamping cylinders 406 simultaneously extends its piston rod, causing multiple sets of clamping elements 407 to move towards each other. The lithium battery components are confined within the space enclosed by the multiple clamping elements 407, which abut against the workpiece sidewall from different directions, restricting the lithium battery components from displacement in the horizontal plane.

[0045] A fixing airbag 408 is mounted on the side of the clamping member 407 facing the lithium battery component. The fixing airbag 408 has a reserved pipeline interface and is connected to an external liquid supply device. The external liquid supply device can deliver a medium into the fixing airbag 408. After the medium is filled, the fixing airbag 408 expands. The expanded fixing airbag 408 directly adheres to the outer wall of the workpiece, and the flexible material of the airbag itself bears the compressive force, avoiding the surface scratches caused by the direct compression of the workpiece outer wall by rigid components. The external liquid supply device can also extract the medium from the fixing airbag 408. After the airbag contracts, the lateral restriction on the lithium battery component is released, making it easy to remove the workpiece.

[0046] A second lifting mechanism is arranged on both the left and right sides of the support platform 401. The mounting plates 405 on both sides of the support platform 401 are fixedly assembled to the power output end of the second lifting mechanism. The second lifting mechanism can drive the mounting plate 405 and the clamping cylinder 406, clamping component 407, and fixing airbag 408 mounted on it to move vertically. When the equipment switches to the adsorption state, or during the process of manual and robotic arm placing lithium battery components, the second lifting mechanism can drive the entire clamping structure to move downward, so that the clamping component 407 and fixing airbag 408 avoid the working area above, reduce the vertical height of the clamping structure, provide sufficient operating space for the placement and alignment of lithium battery components, and completely avoid the working area above the adsorption platform, so as to avoid the clamping structure from obstructing or interfering with the workpiece bearing and adsorption fixing operation of the adsorption platform, and ensure that the adsorption platform can complete the adsorption and clamping process of components normally.

[0047] The first and second lifting mechanisms can share the same structural design, enabling unified component selection, simplified equipment parts types, and reduced manufacturing and spare parts inventory costs. Furthermore, the motion control logic of both lifting mechanisms is consistent, allowing them to share the same drive control program, simplifying the programming and debugging of the overall electrical control system. For example, both can utilize servo screw lifting modules, relying on a servo motor to drive the screw rotation, which in turn moves the sliding seat in a linear lifting motion. This provides features such as position self-locking, adjustable lifting stroke, and consistent response speed. It can meet the lifting requirements for the feed and retraction of the drilling section, as well as the overall lifting and lowering of the mounting plate for obstacle avoidance. The two lifting mechanisms are interchangeable, making equipment assembly, subsequent maintenance, and replacement more convenient.

[0048] like Figure 3 , Figures 8 to 12 As shown, the adsorption platform includes an adsorption shell 501 and an adsorption panel 502. The adsorption shell 501 is fixedly mounted on the power output end of the lifting mechanism. The lifting mechanism can drive the adsorption shell 501 to rise and fall as a whole, simultaneously adjusting the height of the entire adsorption support structure above. The adsorption panel 502 is snapped onto the top of the adsorption shell 501, and the adsorption shell 501 provides bottom support for the adsorption panel 502 and the supporting negative pressure components below. The surface of the adsorption panel 502 is divided into multiple independent adsorption zones. Each adsorption zone has several adsorption through holes drilled through it along the thickness of the plate, enabling airflow communication between the upper and lower spaces of the plate.

[0049] An adsorption box 503 is provided on the lower surface of the adsorption panel 502 for each adsorption area. The upper end face of the adsorption box 503 is attached and fixed to the bottom surface of the adsorption panel 502, and the two together form a closed adsorption cavity. The internal space of the adsorption cavity and the corresponding adsorption through holes are interconnected. The external pipeline of the adsorption box 503 is connected to a negative pressure fan. After the negative pressure fan is started, it continuously draws air from the adsorption cavity, and the air pressure inside the adsorption cavity decreases to form a negative pressure environment. The negative pressure is transmitted to the upper surface of the adsorption panel 502 through the adsorption through holes. The negative pressure suction exerts a downward constraint force on the placed lithium battery components, restricting the horizontal sliding of the workpiece.

[0050] Multiple protective plates 504 are arranged above the adsorption box 503. These protective plates 504, laid above the adsorption panel 502, prevent direct contact between the workpiece and the adsorption panel 502, avoiding scratches and wear on the adsorption panel 502 caused by the workpiece's bottom surface. Each protective plate 504 defines a ventilation zone corresponding to the adsorption area below. Sealing ribs 505 are arranged within each ventilation zone, with their lower ends fixed to the protective plate 504 and their upper ends extending to the top surface of the protective plate 504. Multiple sealing ribs 505 are interlocked to form independent ventilation chambers. These ventilation chambers connect downwards to the adsorption chambers via adsorption through-holes. Several ventilation holes are formed within the ventilation chamber area of ​​the protective plate 504, vertically penetrating the protective plate 504. The ventilation chambers connect to the external space of the equipment via these ventilation holes. Multiple protective plates 504 are arranged and spliced ​​sequentially to form a complete adsorption support platform, on which lithium battery components are placed directly.

[0051] With the above structural design, thin-walled and fragile lithium battery components can be stably clamped and fixed. For workpieces such as conventional small irregularly shaped lithium battery plates and thin lithium battery packaging sheets that are unsuitable for rigid clamping or airbag compression clamping, flat fixing can be achieved by relying on negative pressure adsorption. Utilizing multiple evenly distributed sets of vent holes and vent chambers to transmit negative pressure suction, a uniform adsorption force can be formed on the bottom surface of the workpiece, avoiding local stress concentration that could cause workpiece deformation, while also preventing extrusion damage to the workpiece surface. It is suitable for flat drilling processing conditions of various thin-film and flat-plate lithium battery components, meeting the non-destructive clamping and processing requirements of various lightweight lithium battery components.

[0052] The protective plate 504 is separated into multiple cooling chambers by multiple sealing ribs 505. The cooling chambers and ventilation chambers are arranged alternately on the surface of the protective plate 504. The two types of chambers are isolated from each other. The negative pressure adsorption airflow channel and the cooling airflow channel are not connected to each other. No airflow will occur during their operation, and their respective operation processes will not be interfered with by each other.

[0053] Two partitions 506 are symmetrically installed inside one of the sealing ribs 505 on the protective plate 504. These partitions 506 are fixed within the internal space of the sealing rib 505, dividing the originally interconnected ventilation chamber into two independent flow channels. The ventilation chamber connects downwards to the adsorption chamber, thus the two sets of flow channels also maintain communication with the adsorption chamber. Several flow channels 507 are formed on both side walls of the sealing rib 505. One flow channel 507 connects an adjacent cooling chamber to one of the flow channels, while the other flow channel 507 connects another adjacent cooling chamber to the remaining flow channels. An airflow path is established within the cooling chamber through the flow channels 507 and the flow channels. When the negative pressure fan starts and draws air from the adsorption chamber, the air pressure inside the flow channels decreases synchronously, allowing airflow to be drawn from the corresponding cooling chamber via the flow channels 507, thus driving continuous airflow within the cooling chamber.

[0054] Multiple guide channels 508 are arranged inside the sealing ribs 505 at other locations. The guide channels 508 transversely penetrate the corresponding sealing ribs 505, and adjacent cooling chambers are interconnected through the guide channels 508. Low-temperature airflow can flow through each cooling chamber sequentially along the guide channels 508. This structure works in conjunction with the aforementioned flow guide cavity. All cooling chambers are connected in series through the guide channels 508 to form an overall airflow loop. Only some local cooling chambers are connected to the flow guide cavity through the flow guide groove 507. Relying on the suction action of the negative pressure fan, continuous circulating airflow can be formed inside the entire series of cooling chambers, achieving full-area airflow circulation.

[0055] Two of the protective plates 504 are fitted with cooling boxes 509 at their ends. The internal cavity of the cooling box 509 is interconnected with the internal space of the cooling chamber, allowing airflow to flow smoothly between the cooling box 509 and the cooling chamber. Multiple sets of liquid cooling modules 510 are arranged inside the cooling box 509. An air inlet 511 is opened on the side wall of the cooling box 509, allowing ambient air to continuously enter the cooling box 509 through the air inlet 511. When the incoming air flows over the surface of the liquid cooling module 510, heat exchange is completed, achieving air cooling.

[0056] The liquid cooling module 510 can be a built-in coil-type heat exchange structure. Both ends of the coil of the liquid cooling module 510 are connected to an external coolant supply mechanism via pipelines. The external coolant supply mechanism continuously supplies low-temperature coolant into the coil, achieving reciprocating circulation of the coolant. As the coolant continuously flows through the coil, it continuously absorbs heat from the air inside the cooling chamber 509, lowering the air temperature. The continuous circulation of the coolant removes the heat generated during heat exchange, ensuring that the liquid cooling module 510 can continuously cool and exchange heat with the ambient temperature air entering the cooling chamber 509, stably producing a low-temperature cooling airflow. The cooled airflow is sent into the cooling chamber and flows sequentially through each cooling chamber and the guide channel 508 connecting the cooling chambers, completing the airflow circulation within the entire protective plate 504. Finally, it is discharged through the airflow loop, forming a complete air-cooling heat dissipation path. The continuously flowing low-temperature airflow can carry away the heat accumulated in the protective plate 504 during the drilling operation, reducing the overall temperature of the protective plate 504. At the same time, it continuously dissipates heat from the lithium battery components placed above the protective plate 504, effectively dissipating the processing heat generated during the drilling of the components and preventing the workpiece from overheating locally.

[0057] The adsorption platform is also equipped with multiple sets of lifting components. These lifting components are arranged in a regular manner and pass through the adsorption panel 502 and the protective plate 504. They can form a retractable lifting structure on the surface of the adsorption platform to assist in the unloading of lithium battery components and the separation of workpieces, and are adapted to the workpiece unloading process after negative pressure adsorption and fixation.

[0058] The lifting component includes a lifting sleeve 512 and a lifting rod 513. Multiple sets of first through holes are formed through the adsorption panel 502, providing a fixed installation channel and limiting space for the lifting sleeve 512. A second through hole is formed at the vertical position corresponding to each of the first through holes on the protective plate 504. The second through holes are vertically aligned with the first through holes, forming a through-type installation channel. The lifting sleeve 512 is fixedly inserted into the corresponding first and second through holes, maintaining a vertically fixed state, serving as the vertical movement base for the lifting rod 513 and constraining its lifting trajectory. The lifting rod 513 slides through the internal cavity of the lifting sleeve 512, allowing for vertical extension and retraction along the inside of the lifting sleeve 512. The top end of the lifting rod 513 always protrudes from the upper end of the lifting sleeve 512, located above the protective plate 504, and can directly contact the bottom surface of the lithium battery components placed on the surface of the protective plate 504.

[0059] A spring is fitted at the bottom of the internal cavity of the lifting sleeve 512. The spring is vertically positioned below the bottom of the lifting rod 513, with its upper end supporting the bottom face of the lifting rod 513. In the absence of external force, the spring can support the lifting rod 513 with its own elasticity, maintaining the basic extension height of the lifting rod 513. When the lifting rod 513 is subjected to pressure and retracts downwards, the spring is compressed, generating elastic potential energy. After the pressure is released, the spring releases its elastic potential energy, pushing the lifting rod 513 upwards to reset, thus achieving automatic rebound of the lifting rod 513.

[0060] The side wall of the lifting sleeve 512 is integrally connected with a movable sleeve 514. The internal cavity of the movable sleeve 514 is interconnected with the internal cavity of the lifting sleeve 512. The end of the movable sleeve 514 away from the lifting sleeve 512 is connected to the internal cavity of one of the adsorption boxes 503 through a connecting pipe, so that the air pressure change inside the adsorption box 503 can be directly transmitted to the cavity of the movable sleeve 514, providing a pneumatic power source for the operation of the lifting structure.

[0061] A piston 515 is installed inside the movable sleeve 514. The outer wall of the piston 515 fits snugly against the inner wall of the movable sleeve 514, and the two work together to form a piston movement structure. The piston 515 can slide horizontally back and forth inside the movable sleeve 514. A connecting rope is fixedly connected to the end face of the piston 515 facing the lifting sleeve 512, and the other end of the connecting rope is fixedly connected to the bottom position of the lifting rod 513. When a negative pressure is formed inside the adsorption box 503, the negative pressure airflow will pull the piston 515 to slide away from the lifting sleeve 512. The sliding piston 515 pulls the lifting rod 513 downward through the connecting rope to compress the spring, so that the top of the lifting rod 513 retracts to the state of adhering to the surface of the protective plate 504, avoiding interference of the protruding structure of the lifting rod 513 with the adsorption and adhesion of the workpiece. When the negative pressure fan stops working, the negative pressure inside the adsorption box 503 disappears, and the air pressure returns to normal pressure, the piston 515 is released from its state of tension, and the lifting rod 513 pops up under the elastic force of the bottom spring, lifting the lithium battery components, so that the workpiece is separated from the surface of the protective plate 504, making it easy for the equipment or personnel to remove the material.

[0062] It should be added that when the lithium battery components are placed on the adsorption platform, the bottom surface of the lithium battery components will first contact the top of the lifting rod 513 protruding from the plate surface. The weight of the workpiece itself will create a vertical compressive force on the lifting rod 513. After being compressed, the lifting rod 513 can compress the bottom spring, causing the spring to contract and deform. At this time, the lifting rod 513 moves down slightly, and the lithium battery components are initially placed on top of multiple sets of lifting rods 513. A uniform micro-gap will be left between the bottom surface of the lithium battery components and the top surface of the protective plate 504 to prevent the workpiece from directly contacting the plate surface and to reserve space for airflow during negative pressure adsorption.

[0063] When the negative pressure fan starts, a negative pressure environment is created inside the adsorption box 503. The negative pressure airflow is introduced into the movable sleeve 514 through the connecting pipe, pulling the piston 515 to slide along the inside of the movable sleeve 514. During the sliding process, the piston 515 pulls the lifting rod 513 through the connecting rope, causing the lifting rod 513 to retract further downward and be completely stored inside the lifting sleeve 512. The top of the lifting rod 513 falls back to below the surface of the protective plate 504. At this time, the lithium battery components that were originally supported above the lifting rod 513 lose their support points and sink down to fit against the top surface of the protective plate 504. The bottom surface of the workpiece completely covers the adsorption and ventilation area, ensuring that the negative pressure suction can be evenly and fully applied to the bottom surface of the workpiece, achieving stable adsorption and fixation of the lithium battery components.

[0064] After the drilling process is completed, the negative pressure fan stops running, the negative pressure inside the adsorption box 503 and the movable sleeve 514 is released, the tension on the piston 515 disappears, and it no longer exerts a pulling effect on the lifting rod 513. At this time, the compressed spring inside the lifting sleeve 512 releases its elastic potential energy, pushing the lifting rod 513 upward to reset and extend. Multiple sets of lifting rods 513 extend out of the plate surface simultaneously, lifting the lithium battery components from the bottom, separating the workpiece from the surface of the protective plate 504, eliminating the adhesion resistance between the workpiece and the plate surface, and facilitating the subsequent automatic material handling mechanism or manual removal of the workpiece.

[0065] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
