Description

Technical Field

[0001] This application relates to the field of powder metallurgy automation technology, and in particular to a thermoelectric cell pressing device and method. Background Technology

[0002] Thermal cells are key components manufactured by pressing special powders into shape, and their density and uniformity directly affect the performance of the battery. In automated production, a series of pretreatments are usually required, such as feeding, leveling, and pre-pressing a fixed amount of powder.

[0003] Existing automation solutions typically employ a multi-station assembly line layout, with independent loading, leveling, and pre-pressing stations. Powder-filled molds are sequentially transported to different stations via conveyor belts or rotary tables for processing. However, while this decentralized approach achieves automation, it suffers from drawbacks such as large overall equipment footprint, complex structure, and potential errors introduced by transfers and repetitive positioning between processes, affecting product consistency. Furthermore, the combination of multiple independent workstations increases equipment cost and maintenance complexity. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems in the prior art, namely the problems of large equipment footprint, complex structure, low integration and low process conversion efficiency caused by the multi-station decentralized processing of the existing automated pressing equipment, the embodiments of this application provide a compact and highly integrated thermal cell pressing device and method.

[0005] In a first aspect of this application, a thermal cell pressing apparatus is provided, comprising:

[0006] The frame includes a first frame and a second frame, one side of the first frame is connected to one side of the second frame, and the top of the first frame is higher than the top of the second frame;

[0007] The conveyor line, installed on top of the second frame, is used to carry and transport the powder forming tooling.

[0008] The powder forming fixture is placed on the conveyor line. The powder forming fixture is used to receive and contain the powder raw materials fed by the powder feeding mechanism, and to drive the powder feeding mechanism to rise or fall when it is driven to rise and fall by the lifting and positioning mechanism. After the powder feeding mechanism is removed, it cooperates with the pressing head of the lifting and positioning mechanism and the material handling mechanism to press the received powder raw materials.

[0009] The lifting and positioning mechanism is installed on the second frame and located below the conveyor line. The output end of the lifting and positioning mechanism is used to position the powder forming tool through the conveyor line and drive the powder forming tool to rise or fall.

[0010] The powder feeding mechanism is used to hold powder raw materials. When the powder feeding mechanism is placed on the powder forming fixture, it is used to cooperate with the material feeding mechanism to feed the powder forming fixture, and after feeding is completed, it is removed from the material feeding mechanism and taken away.

[0011] A movable slide is installed on top of the first frame;

[0012] The material handling mechanism is fixedly installed on the slider of the movable slide table. When the slider is in the front position, the smearing plate of the material handling mechanism is located above the powder forming fixture and the powder feeding mechanism placed on the powder forming fixture. The smearing plate is used to smooth the powder raw material contained in the powder feeding mechanism before the powder feeding mechanism feeds the powder forming fixture, so that the powder layer thickness of the powder raw material in the powder feeding mechanism is uniform. The pressure head and the smearing plate are installed on the material handling top plate of the material handling mechanism.

[0013] Optionally, the powder feeding mechanism includes:

[0014] A receiving container is provided with a receiving hole for holding powder raw materials. The bottom of the receiving container has four protruding feet at the four corners. At least one through feeding positioning hole is provided on the part of the receiving container between adjacent feet.

[0015] The guide rail consists of two parallel rails, which are set at the four feet of the receiving container and located between the bottom of the receiving container and the pressure block, with the guide rails located on the inner side of the feet respectively.

[0016] A pull-out plate is mounted on a guide rail and slides along the guide rail. The feeding positioning hole is located on the outside of the pull-out plate. One end of the pull-out plate is equipped with a baffle, and the other end is equipped with a feeding hole. The baffle is located on the outside of the receiving container and is used to contact the outer wall of the receiving container to prevent the pull-out plate from moving towards the push-pull plate of the material handling mechanism. When the feeding hole moves with the pull-out plate to directly below the receiving hole, the receiving hole is completely exposed from the feeding hole. When the baffle contacts the outer wall of the receiving container, the part of the pull-out plate other than the feeding hole completely closes the receiving hole to serve as the bottom of the receiving hole to accommodate the powder raw material.

[0017] Optionally, the powder feeding mechanism further includes:

[0018] Four pressure blocks are placed at the bottom of the four feet of the receiving container.

[0019] At least one buffer block is provided on the outer wall of the pull-out plate away from the baffle and perpendicular to the guide rail, and is made of iron.

[0020] Optionally, the powder forming tooling includes:

[0021] Mold base plate;

[0022] Mold base pillar, installed on the mold base plate;

[0023] The outer ring of the mold is installed on the top of the bottom column of the mold. The outer ring of the mold and the top of the bottom column of the mold form a closed receiving hole for receiving and accommodating the powder raw material fed by the powder feeding mechanism.

[0024] At least one tooling positioning hole is provided in and through the mold base plate for engaging with at least one tooling positioning pin of the lifting positioning mechanism.

[0025] Optionally, the powder forming fixture also includes:

[0026] The guide shaft is mounted on the mold base plate and located on the outside of the mold bottom pillar;

[0027] The guide seat is fitted onto the top of the guide shaft and connected to the outer wall of the outer ring of the mold;

[0028] The guide spring is fitted onto the guide shaft and located between the guide seat and the mold base plate.

[0029] Optionally, the powder forming fixture also includes:

[0030] An oil-free bushing is fitted onto the guide shaft and located between the guide seat and the guide spring.

[0031] The handles are installed at both ends of the mold base plate and are located outside the guide spring and the mold base pillar.

[0032] Optionally, the lifting and positioning mechanism includes:

[0033] Lifting cylinder, the cylinder body of the lifting cylinder is mounted on the second frame;

[0034] The lifting plate, installed at the output end of the lifting cylinder, is used to pass through the middle hole of the conveyor line and contact the mold base plate of the powder forming tool, thereby driving the powder forming tool to rise or fall.

[0035] At least one tooling locating pin is installed on the top of the lifting plate for engaging with at least one tooling locating hole of the powder forming tooling to position the powder forming tooling.

[0036] Optionally, the material handling mechanism includes:

[0037] A sliding support plate, a slider fixedly installed on a movable slide table;

[0038] The material sorting rack includes a material sorting top plate and a Π-shaped frame. The bottom of the Π-shaped frame is fixed to a sliding support plate, and the material sorting top plate is connected to the top of the Π-shaped frame and is perpendicular to the Π-shaped frame.

[0039] At least one receiving port positioning pin is installed on the lower side of the material feeding top plate to cooperate with at least one feeding positioning hole of the powder feeding mechanism to position the powder feeding mechanism.

[0040] At least one release spring is mounted on the lower side of the top plate of the feeding mechanism, for contacting and being compressed with the top of the receiving container of the powder feeding mechanism when the powder feeding mechanism rises, and for extending to provide a descending thrust for the powder feeding mechanism when the powder feeding mechanism descends.

[0041] A rotary drive unit is installed on the upper side of the material feeding top plate. The output end of the rotary drive unit passes through the material feeding top plate and is connected to the trowel plate to drive the trowel plate to rotate.

[0042] The smearing plate is installed on the lower side of the material feeding top plate and connected to the output end of the rotary drive component. When the locating pin of the receiving port is inserted into the feeding positioning hole of the powder feeding mechanism, the smearing plate is located directly above the receiving hole of the receiving container.

[0043] The pressure head is installed on the lower side of the top plate of the material feeding device. When the squeegee is located directly above the receiving hole of the receiving container and in contact with the receiving hole, the pressure head is located outside the powder feeding mechanism and suspended. When the pressure head is aligned with the receiving hole of the powder forming tool and in contact with the powder material in the receiving hole, the receiving port positioning pin and the demolding spring are both located outside the powder forming tool and suspended.

[0044] The cylinder body of the pull-out electric cylinder is mounted on the sliding bearing plate, and the cylinder body is located on the side of the Π-shaped frame away from the pressure head;

[0045] The push-pull plate is installed at the output end of the pull-out electric cylinder and has a magnet. The push-pull plate is used to pass through the middle channel of the Π-shaped frame and attract the pull-out plate of the powder feeding mechanism, thereby driving the pull-out plate to move. The side of the pull-out plate that attracts the push-pull plate is made of iron.

[0046] Optionally, the material handling mechanism may also include:

[0047] Two right-angled triangular support plates are located on both sides of the top plate of the material handling system. The two right-angled sides of the right-angled triangular support plates are connected to the bottom of the top plate of the material handling system and a vertical side of the Π-shaped frame, respectively.

[0048] In a second aspect of this application, a method for pressing a thermal cell based on the above-described thermal cell pressing apparatus is provided, comprising:

[0049] The control system controls the robot to place the powder feeding mechanism on the powder forming fixture on the conveyor line, and makes the receiving hole of the powder feeding mechanism coaxial with the receiving hole of the powder forming fixture.

[0050] The control system controls the slider of the moving slide to move, driving the material handling mechanism to move towards the powder feeding mechanism until the material handling mechanism's receiving port positioning pin is aligned with the powder feeding mechanism's feeding positioning hole.

[0051] The control system controls the lifting and positioning mechanism to lift upwards, so that the tooling positioning pin of the lifting and positioning mechanism passes through the tooling positioning hole of the powder forming tool, lifting the powder forming tool, and driving the powder feeding mechanism to rise through the powder forming tool, so that the receiving port positioning pin of the material handling mechanism passes through the feeding positioning hole of the powder feeding mechanism. At the same time, the demolding spring is compressed until the powder feeding mechanism is lifted into place, and the smearing plate of the material handling mechanism contacts the receiving hole of the powder feeding mechanism. The control system controls the rotation drive of the material handling mechanism to rotate the smearing plate to smooth the powder material in the receiving hole of the powder feeding mechanism.

[0052] The control system controls the extension of the pull rod of the pull cylinder of the feeding mechanism, pushes the push plate to move towards the pull plate of the powder feeding mechanism, and continues to push the push plate after the push plate adsorbs the pull plate. The push plate drives the pull plate to move along the guide rail until the receiving hole of the powder feeding mechanism completely leaks out from the feeding hole, and the powder raw material in the receiving hole falls from the feeding hole into the receiving hole of the powder forming tool.

[0053] The control system controls the retraction rod of the pull-out electric cylinder of the material feeding mechanism to retract, driving the push-pull plate to move away from the receiving container. The push-pull plate drives the adsorbed pull-out plate to move along the guide rail. After the baffle of the pull-out plate contacts the receiving container, the pull-out plate stops moving due to the obstruction of the baffle. The control system then controls the pull-out rod of the pull-out electric cylinder to continue retracting, driving the push-pull plate to detach from the pull-out plate. After the push-pull plate detaches from the pull-out plate, the control system controls the lifting and positioning mechanism to descend, causing the feeding positioning hole of the powder feeding mechanism to disengage from the receiving port positioning pin of the material feeding mechanism under the action of the descent of the lifting and positioning mechanism and the elastic force of the demolding spring.

[0054] The control system controls the movement of the slider of the moving slide table, which drives the material feeding mechanism to move a preset distance away from the powder feeding mechanism;

[0055] The control system controls the robotic arm to remove the powder feeding mechanism;

[0056] The control system controls the slider of the moving slide to move, driving the feeding mechanism to move towards the powder forming fixture until the pressure head of the feeding mechanism is directly above the receiving hole of the powder forming fixture and coaxial with the receiving hole.

[0057] The control system controls the lifting and positioning mechanism to lift upwards, causing the powder forming fixture to rise a preset distance, so that the powder material in the receiving hole is flattened under the pressure of the pressure head and the pushing force of the lifting and positioning mechanism on the powder forming fixture.

[0058] The control system controls the lifting and positioning mechanism to descend, which in turn drives the powder forming tooling down to the conveyor line;

[0059] After the powder forming fixture descends to the conveyor line, the control system controls the lifting and positioning mechanism to continue descending, causing the fixture positioning pin of the lifting and positioning mechanism to disengage from the fixture positioning hole of the powder forming fixture.

[0060] The control system controls the conveyor line to transport the powder forming tool to the next station.

[0061] The beneficial effects of this invention are as follows:

[0062] Compared with the prior art, the beneficial effects of the thermal cell pressing solution provided in this application are as follows: By integrating multiple functions such as smoothing and pre-pressing into a single tool component, and using a motion system to drive the tool component to complete sequential operations at a single station, multiple pre-processing steps are integrated into a single station, eliminating the need for multiple independent workstations, greatly reducing the equipment footprint, simplifying the equipment structure, and thus reducing manufacturing costs and maintenance difficulty; all pre-processing steps are completed in a single station, eliminating the need to transfer molds between stations, significantly improving production efficiency by reducing transfer time between processes; at the same time, it avoids the cumulative errors caused by multiple transfers and repeated positioning, ensuring the accuracy of powder processing, and improving the consistency and yield of the final product.

Detailed Implementation

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be considered as limitations on this application. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit this application.

[0075] A first aspect of this application provides a thermal cell pressing apparatus. For example... Figures 1-5As shown, the thermal cell pressing device includes a frame 101, a conveyor line 107, a powder forming fixture 105, a lifting and positioning mechanism 106, a powder feeding mechanism 104, a moving slide 102, and a material handling mechanism 103. The frame 101 serves as the supporting foundation for the entire device, comprising a first frame and a second frame. One side of the first frame is connected to one side of the second frame, meaning the two frames are integrated through one side. The top of the first frame is higher than the top of the second frame. This staggered design provides suitable installation space for mechanisms with different functions. The conveyor line 107 is installed on top of the lower second frame and is used to carry the powder forming fixture 105 and automatically transport it, enabling the powder forming fixture 105 to move between different workstations. The conveyor line 107 is a frame type with a hollow center. The powder forming fixture 105 is placed on the conveyor line 107. It serves as a mold to receive and hold the powder raw material fed by the powder feeding mechanism 104. When lifted and lowered by the lifting and positioning mechanism 106, it also drives the powder feeding mechanism 104 to rise or fall. Finally, after the powder feeding mechanism 104 is removed, it cooperates with the lifting and positioning mechanism 106 and the pressure head 402 of the material handling mechanism 103 to form the received powder raw material under pressure. The lifting and positioning mechanism 106 is installed below the conveyor line 107 of the second frame. Its output end can move upwards, passing through the hollow in the middle of the conveyor line 107 to contact the bottom of the powder forming fixture 105, achieving precise positioning and vertical lifting of the powder forming fixture 105. The powder feeding mechanism 104 is a movable container used to hold the powder raw materials to be pressed. The powder feeding mechanism 104 is placed on the powder forming fixture 105 by a moving mechanism (e.g., a robot arm) and cooperates with the material handling mechanism 103 to complete the feeding of powder into the powder forming fixture 105. After feeding is completed, it is removed from the material handling mechanism 103 and moved away (e.g., by the robot arm). The movable slide 102 is installed on the top of the higher first frame to provide the material handling mechanism 103 with the freedom of horizontal movement. The movable slide 102 can be a ball screw linear module, a cylinder slide (e.g., a magnetic couple rodless cylinder slide), etc. The material handling mechanism 103 is fixedly installed on the slider of the movable slide table 102. By moving the slider, the material handling mechanism 103 can switch between different working positions. The material handling mechanism 103 integrates a smearing plate 403 and a pressing head 402. When the slider moves to the front position, the smearing plate 403 can smooth the powder in the powder feeding mechanism 104 to ensure that the material layer thickness is uniform. After the powder feeding mechanism 104 is removed, the material handling mechanism 103 can move again to align the pressing head 402 on it with the powder forming fixture 105. With the lifting and positioning mechanism 106, the pre-compression of the powder raw material is completed.

[0076] Specifically, such as Figure 2As shown, the powder feeding mechanism 104 includes a receiving container 201, four pressure blocks 203, two parallel guide rails 204, and a pull-out plate 202. The receiving container 201 has a receiving hole in the center for holding powder raw materials. Protruding feet are provided at the four corners of the bottom of the receiving container 201 to allow it to be stably placed on the powder forming fixture 105, while also providing movement space for the pull-out plate 202 below. At least one through-hole feeding positioning hole 205 is provided on the container wall between adjacent feet to cooperate with the receiving port positioning pin on the material handling mechanism 103, ensuring precise positioning of the powder feeding mechanism 104. Pressure blocks 203 can also be provided on the powder feeding mechanism 104, located at the bottom of the four feet, serving a supporting and wear-resistant function. Two parallel guide rails 204 are located on the inner side of the foot, between the bottom of the receiving container 201 and the pressure block 203, providing a sliding path for the pull-out plate 202. The pull-out plate 202 is mounted on the guide rails 204 and slides along them. The feeding positioning hole 205 is located on the outer side of the pull-out plate 202. One end of the pull-out plate 202 has a baffle 207, and the other end has a feeding hole 208. In the initial state, the main body of the pull-out plate 202 completely closes the bottom of the receiving hole of the receiving container 201, forming a bottom-closed accommodating space (cavity) for accommodating powder raw materials. When feeding is required, the push-pull plate 406 of the feeding mechanism 103 drives the pull plate 202 to slide, causing the feeding hole 208 on the pull plate 202 to move directly below the receiving hole. At this time, the powder will fall from the feeding hole 208 into the powder forming fixture 105 due to gravity. The baffle 207 is used for limiting. When the pull plate 202 is pulled back to the initial position, the baffle 207 contacts the outer wall of the receiving container 201 to prevent the pull plate 202 from moving excessively (preventing the pull plate 202 from moving excessively toward the feeding mechanism 103, specifically, preventing the pull plate 202 from moving excessively toward the push-pull plate 406 of the feeding mechanism 103, or preventing the pull plate 202 from moving excessively toward the pressure head 402 away from the feeding mechanism 103), ensuring that the receiving hole is reliably closed again. The baffle 207 can be a single plate with a width greater than the width of the receiving container 201, located at the end of the pull-out plate 202. Alternatively, it can be two baffles located on either side of the end of the pull-out plate 202, forming a T-shape with the main body of the pull-out plate 202. These baffles contact the outer wall of the receiving container 201 to limit the movement of the pull-out plate 202. At least one buffer block 206 can also be provided on the powder feeding mechanism 104. The buffer block 206 is located on the outer wall of the pull-out plate 202 away from the baffle 207 and perpendicular to the guide rail 204. The buffer block 206 is made of iron. For example,... Figure 2There are two buffer blocks 206 shown, and they are symmetrical with respect to the central axis of the pull plate 202 (parallel to the central axis of the guide rail 204). The buffer blocks 206 are used to form a buffer between the outer wall of the pull plate 202 and the push plate 406 to prevent the push plate 406 from impacting the outer wall of the pull plate 202 during the movement of the pull plate 202. Figure 2 The diagram also shows a cross-sectional view of the receiving container and the pull-out plate, such as... Figure 2 The mid-section is shown in schematic 209.

[0077] Specifically, such as Figure 3 As shown, the powder forming fixture 105 includes a mold base plate 301, a mold base pillar 302, and a mold outer ring 303. The mold base plate 301 is the foundation of the entire fixture, providing a platform for installing other components. The mold base pillar 302 is vertically mounted on the mold base plate 301, and its top surface forms the bottom surface where the pressed and formed thermal battery sheet will be located. The mold outer ring 303 is mounted on the top of the mold base pillar 302, and its inner wall and the outer edge of the top surface of the mold base pillar 302 together form a cylindrical receiving hole with a closed bottom. The receiving hole is a mold cavity for receiving powder raw materials falling from the powder feeding mechanism 104 and defining the final shape of the powder raw materials. In addition, at least one tooling positioning hole is provided on the mold base plate 301, which penetrates the mold base plate 301. The tooling positioning hole is used to precisely cooperate with the tooling positioning pin of the lower lifting positioning mechanism 106. The pin hole cooperation ensures that when the lifting positioning mechanism 106 lifts the powder forming tooling 105, it can not only provide a stable vertical force, but also accurately position the powder forming tooling 105 in the horizontal direction, preventing displacement during lifting and pressing, so as to ensure the consistency of the thermal cell product.

[0078] Specifically, such as Figure 3 As shown, the powder forming fixture 105 may further include a guide shaft 306, a guide seat 304, a guide spring 305, an oil-free bushing 307, and a handle 308. The guide shaft 306 is vertically mounted on the mold base plate 301, located outside the mold base pillar 302, serving as a reference for motion guidance. The guide seat 304 is fitted onto the top of the guide shaft 306 and connected to the outer wall of the mold outer ring 303. The guide spring 305 is fitted onto the guide shaft 306, located between the guide seat 304 and the mold base plate 301, and is in a pre-compressed state. The guide spring 305 stores elastic energy and can provide an auxiliary thrust when the mold outer ring 303 is subsequently demolded from the pressed powder material (thermal battery sheet), assisting in the demolding of the finished product from the powder forming fixture 105. Oil-free bushing 307 is fitted onto guide shaft 306, located between guide seat 304 and guide spring 305, providing a low-friction contact surface for the sliding of guide seat 304 along guide shaft 306 to ensure smooth and precise movement. Handles 308 are installed at both ends of mold base plate 301 for easy manual handling and maintenance.

[0079] Specifically, such as Figure 1 and Figure 5 As shown, the lifting and positioning mechanism 106 includes a lifting cylinder, a lifting plate, and at least one tooling positioning pin. The cylinder body of the lifting cylinder is fixedly installed below the second frame, serving as the source of vertical power. The cylinder has the advantages of fast response and simple control. The lifting plate is installed at the output end of the lifting cylinder (such as the end of the piston rod) and is a planar component with an area sufficient to stably support the bottom of the entire powder forming fixture 105. When the cylinder actuates, the lifting plate passes through the pre-reserved hollow area in the middle of the conveyor line 107, contacts the bottom of the mold base plate 301 of the powder forming fixture 105, and drives the powder forming fixture 105 to rise or fall as a whole. At least one tooling positioning pin is vertically installed on the top of the lifting plate, and the shape, size, and position of the tooling positioning pin correspond to the tooling positioning holes on the powder forming fixture 105. In the initial stage of the lifting plate's ascent, the tooling positioning pin inserts into the tooling positioning hole of the powder forming tool 105 before the plane of the lifting plate, thereby locking the powder forming tool 105 in the horizontal direction and preventing it from sliding or rotating. Subsequently, the lifting plate can continue to rise, providing stable vertical thrust. The lifting positioning mechanism 106 can also be other drive mechanisms such as a servo electric cylinder lifting assembly or a cam-linkage lifting mechanism.

[0080] Specifically, such as Figure 4 As shown, the material handling mechanism 103 includes a sliding support plate 410, a material handling rack 401, at least one receiving port positioning pin, at least one demolding spring 405, a rotary drive component, a squeegee 403, a pressure head 402, a pull-out electric cylinder 404, and a push-pull plate 406. The material handling rack 401 is fixed to the sliding support plate 410, which in turn is fixed to the slider of the movable slide table 102. The material handling rack 401 consists of a Π-shaped frame 411 and a material handling top plate 409. The material handling top plate 409 is horizontally connected to the top of the Π-shaped frame 411, forming a cantilever structure, under which multiple functional components (receiving port positioning pin, demolding spring, squeegee, and pressure head) are integrated. In one possible embodiment, two right-angled triangular support plates can also be added between the Π-shaped frame 411 and the material handling top plate 409, such as... Figure 5 As shown, two right-angled triangular support plates are located on both sides of the material handling top plate 409. The two sides of the right angle of the right-angled triangular support plates are connected to the bottom of the material handling top plate 409 and a vertical side of the Π-shaped frame 411, respectively. The right-angled triangular support plates provide stable support for the material handling top plate 409, improving the stability of the material handling top plate 409. At least one material receiving port positioning pin (such as...) is installed on the lower side of the material handling top plate 409. Figure 4The receiving port positioning pins (cylindrical pins) 407 and (diamond pins) 408 shown can all be cylindrical pins or all be diamond pins. Using different shapes of positioning pins can prevent them from falling off together and improve positioning stability. The receiving port positioning pins are used to cooperate with the feeding positioning hole 205 on the powder feeding mechanism 104 to achieve precise alignment between the material handling mechanism 103 and the powder feeding mechanism 104. At the same time, the material handling mechanism 103 is also equipped with at least one demolding spring 405. When the powder feeding mechanism 104 is lifted, its top will contact and compress the demolding spring. The stored elastic energy can provide thrust during subsequent descent to assist the feeding positioning hole 205 in quickly disengaging from the receiving port positioning pin. The smearing plate 403 is also installed on the lower side of the material handling top plate 409 and is driven to rotate by a rotary drive (such as a small motor) passing through the top plate. It is used to smooth the powder raw materials. Specifically, the rotary drive is installed on the upper side of the material handling top plate 409. The output end of the rotary drive passes through the material handling top plate 409 and is connected to the smearing plate 403 to drive the smearing plate 403 to rotate. The smearing plate 403 is installed on the lower side of the material handling top plate 409 and is connected to the output end of the rotary drive. When the material receiving port positioning pin is inserted into the feeding positioning hole 205 of the powder feeding mechanism 104, the smearing plate 403 is located directly above the receiving hole of the receiving container 201. The pressure head 402 is also installed on the lower side of the material feeding top plate 409. When the material feeding mechanism 103 is in the smoothing position (that is, when the smoothing plate 403 is directly above the receiving hole of the receiving container 201 and in contact with the receiving hole), the pressure head 402 is located outside the powder feeding mechanism 104 and is suspended. When the material feeding mechanism 103 moves to the pressing position (that is, when the pressure head 402 is aligned with the receiving hole of the powder forming fixture 105 and in contact with the powder raw material in the receiving hole), the pressure head 402 is aligned with the receiving hole of the powder forming fixture 105. At this time, the receiving port positioning pin and the demolding spring 405 are both located outside the powder forming fixture 105 and are suspended. In the material handling mechanism 103, the cylinder body of the pull-out electric cylinder 404 is mounted on the sliding bearing plate 410, located on the side of the Π-shaped frame 411 away from the pressure head 402. Its output end is connected to a push-pull plate 406 with a magnet. The push-pull plate 406 can pass through the middle channel of the Π-shaped frame 411 and be attracted to the pull-out plate 202 of the powder feeding mechanism 104 (the corresponding surface of which is iron). The pull-out plate 202 is moved by the extension and retraction of the electric cylinder to complete the feeding and resetting actions. When a buffer block 206 is provided on the pull-out plate 202, the buffer block 206 is attracted to the pull-out plate 202.

[0081] The working process of the thermal cell pressing device provided in this application embodiment is as follows:

[0082] First, an external robotic arm loads a powder feeding mechanism 104 (e.g., a powder feeding machine that has already been filled and weighed by a powder raw material filling machine) into a powder feeding device. Figure 2The structure shown is placed on an empty powder forming fixture 105 located on conveyor line 107 (as shown). Figure 3 On the structure shown, and ensure that the receiving hole of the powder feeding mechanism 104 is coaxial with the receiving hole of the powder forming tool 105 below;

[0083] Subsequently, the control system drives the slider of the moving slide 102 to move, thereby driving the entire material handling mechanism 103 (such as...). Figure 4 The structure shown moves from the initial position toward the powder feeding mechanism 104 until the receiving port positioning pin (407, 408) below the material handling mechanism 103 moves directly above the feeding positioning hole 205 of the powder feeding mechanism 104 and aligns with the feeding positioning hole 205 of the powder feeding mechanism 104.

[0084] Next, the control system activates the lifting and positioning mechanism 106, for example, by controlling the piston rod of the lifting cylinder to extend, causing the lifting plate and the tooling positioning pin on it to move upward. The tooling positioning pin first inserts into the tooling positioning hole at the bottom of the powder forming tool 105, completing the horizontal locking of the tool. As the lifting plate continues to rise, the powder forming tool 105 is smoothly lifted, which in turn drives the powder feeding mechanism 104 above it to rise together. During the rising process, the feeding positioning hole 205 of the powder feeding mechanism 104 will be sleeved on the receiving port positioning pin (407, 408) of the material handling mechanism 103, realizing the precise positioning of the powder feeding mechanism 104 and the material handling mechanism 103. At the same time, the top of the powder feeding mechanism 104 will contact and compress the demolding spring 405 on the material handling mechanism 103, and the lifting continues until the smearing plate 403 contacts the receiving hole (and also contacts the surface of the powder raw material in the receiving hole), at which point the lifting is in place.

[0085] After being lifted into position, the control system controls the rotating drive component on the material handling mechanism 103 to rotate the smearing plate 403 by a certain angle or number of revolutions. The rotation of the smearing plate 403 can scrape off the powder that is raised in the receiving hole and fill the low places, thereby smoothing the surface of the powder raw material and ensuring that the powder filling height and density in the entire receiving hole are uniform.

[0086] After the smoothing operation is completed, the control system controls the extension rod of the pull-out electric cylinder 404 of the material feeding mechanism 103 to push the push-pull plate 406 with a magnet through the channel of the Π-shaped frame 411 and move towards the pull-out plate 202 of the powder feeding mechanism 104. When the push-pull plate 406 approaches the pull-out plate 202, its magnet will attract the iron pull-out plate 202 (or the side of the pull-out plate 202 that contacts the push-pull plate 406 is iron). The pull-out rod of the pull-out electric cylinder 404 continues to extend, and through the push-pull plate 406, it drives the pull-out plate 202 to slide along the guide rail 204 until the receiving hole is completely exposed above the feeding hole 208 on the pull-out plate 202. At this time, the smoothed powder raw material in the receiving hole will fall from the feeding hole 208 into the receiving hole of the powder forming fixture 105 below under the action of gravity, completing the feeding.

[0087] After feeding is completed, the control system controls the pull rod of the pull cylinder 404 to retract, that is, to move away from the receiving container 201. Due to magnetic attraction, the retracting push plate 406 will drive the pull plate 202 to retract as well, so that the pull plate 202 re-closes the receiving hole. When the pull plate 202 moves to the point where the baffle 207 at its end contacts the outer wall of the receiving container 201, the pull plate 202 stops moving due to obstruction. At this time, the control system controls the pull rod of the pull cylinder 404 to continue to retract a small distance (this distance can be preset). The pulling force generated by this action will overcome the magnetic attraction force, so that the push plate 406 and the pull plate 202 are separated.

[0088] After the push-pull plate 406 disengages from the pull-out plate 202, the control system controls the lifting and positioning mechanism 106 to descend. Under the combined action of the retraction force of the lifting and positioning mechanism 106 (e.g., the retraction force of the lifting cylinder) and the elastic force of the compressed demolding spring 405 on the material handling mechanism 103, the powder feeding mechanism 104 and the powder forming fixture 105 will descend smoothly, and the feeding positioning hole 205 of the powder feeding mechanism 104 will smoothly disengage from the receiving port positioning pin of the material handling mechanism 103.

[0089] After descending to a certain position (for example, the lifting plate of the lifting and positioning mechanism 106 descends to a certain position, which can be preset and controlled by the control system), the control system controls the slider of the moving slide table 102 to move, driving the material handling mechanism 103 to move a preset distance away from the powder feeding mechanism 104, leaving space for subsequent robot operation. Then, the control system controls the robot to remove the emptied powder feeding mechanism 104 from the powder forming fixture 105 and send it for the next round of feeding.

[0090] Next, the pre-pressing process begins. The control system again controls the slider of the moving slide table 102 to move, driving the material handling mechanism 103 to another preset pressing station. This station position ensures that the pressing head 402 on the material handling mechanism 103 is precisely located above the receiving hole of the powder forming fixture 105 below, and is coaxial with the receiving hole. Then, the control system again controls the lifting and positioning mechanism 106 to lift upward, driving the powder forming fixture 105 carrying powder to rise a preset distance. During this process, the loose powder material in the receiving hole will come into contact with the stationary pressing head 402, and be compacted and flattened under the combined action of the reaction force provided by the pressing head 402 and the continuous thrust provided by the lifting and positioning mechanism 106, thus completing the pre-pressing process.

[0091] After the pre-compression is completed, the control system controls the lifting and positioning mechanism 106 to descend, which drives the powder forming tool 105 to descend smoothly back to the conveyor line 107.

[0092] After the powder forming fixture 105 is stabilized on the conveyor line 107, the control system controls the lifting and positioning mechanism 106 to continue to descend, so that the tooling positioning pin of its lifting plate is completely removed from the bottom of the powder forming fixture 105 (and also removed from the tooling positioning hole of the powder forming fixture 105), and returns to the initial standby position.

[0093] Finally, the control system controls the operation of the conveyor line 107 to transfer the pressed semi-finished thermal cell powder forming fixture 105 to the next station (e.g., the final pressing or stacking station). If the entire thermal cell pressing process does not stop, the control system will also control the upstream station or robot to place a new, empty powder forming fixture 105 onto the conveyor line 107 of this station, aligning its fixture positioning hole with the fixture positioning pin of the lifting positioning mechanism 106 below, ready to start the next cycle. The thermal cell pressing device provided in this application embodiment realizes fully automated closed-loop control from powder raw material feeding, leveling, feeding to pre-pressing, significantly improving production efficiency, product consistency and process stability.

[0094] A second aspect of this application provides a method for pressing a thermal cell based on the above-described thermal cell pressing apparatus, the method comprising:

[0095] The control system controls an external robotic arm to place a powder feeding mechanism 104 pre-filled with powder raw materials onto a powder forming fixture 105 located on a conveyor line 107, and aligns the receiving hole of the powder feeding mechanism 104 with the receiving hole of the powder forming fixture 105 in the vertical direction (coaxial). Subsequently, the control system drives the movable slide 102, causing its slider to move the material handling mechanism 103 along the guide rail of the movable slide 102 in the first frame towards the powder feeding mechanism 104, until the receiving port positioning pin below the material handling mechanism 103 is precisely moved to the top of the feeding positioning hole 205 above the powder feeding mechanism 104, so that the receiving port positioning pin of the material handling mechanism 103 is aligned with the feeding positioning hole 205 of the powder feeding mechanism 104, completing the initial alignment of the material handling mechanism 103.

[0096] The control system controls the lifting and positioning mechanism 106 to begin lifting upwards. The tooling positioning pin of the lifting and positioning mechanism 106 first passes through the tooling positioning hole of the powder forming tool 105 to achieve horizontal locking of the powder forming tool 105. As the lifting continues, the powder forming tool 105 and the powder feeding mechanism 104 above it are lifted together until the feeding positioning hole 205 of the powder feeding mechanism 104 is fully engaged with the receiving port positioning pin of the material handling mechanism 103. At the same time, the demolding spring 405 on the material handling mechanism 103 is compressed. When the lifting reaches the predetermined height (lifting in place), and the smearing plate 403 of the material handling mechanism 103 contacts the receiving hole of the powder feeding mechanism 104 (and simultaneously contacts the powder surface in the receiving hole) or reaches the preset position, the lifting stops. Then, the control system controls the rotation drive of the material handling mechanism 103 to drive the smearing plate 403 to rotate, scraping and smoothing the powder material in the receiving hole to ensure uniform powder layer thickness.

[0097] The control system controls the extension of the pull-out electric cylinder 404 of the feeding mechanism 103, pushing the push-pull plate 406 at its end to move and magnetically attract the pull-out plate 202 of the powder feeding mechanism 104, and drives the pull-out plate 202 to slide along the guide rail 204 of the powder feeding mechanism 104 until the receiving hole of the powder feeding mechanism 104 completely leaks out from the feeding hole 208, so that the powder raw material falls into the receiving hole of the powder forming fixture 105 below; after the feeding is completed, the control system controls the pull-out electric cylinder 404 to retract, and pulls the pull-out plate 202 back to its original position through the push-pull plate 406 to close the receiving hole from the bottom, and after the pull-out plate 202 is limited by the baffle 207, it continues to retract so that the push-pull plate 406 and the pull-out plate 202 are separated from the magnetic attraction;

[0098] After the pull plate 202 is reset, the control system controls the lifting and positioning mechanism 106 to descend. Under the combined action of the descending force and the elastic force of the demolding spring 405, the feeding positioning hole of the powder feeding mechanism 104 is disengaged from the receiving port positioning pin of the material handling mechanism 103. Subsequently, the control system controls the moving slide 102 to move the material handling mechanism 103 away and controls the robot to take away the empty powder feeding mechanism 104. Then, the control system controls the moving slide 102 again to move the material handling mechanism 103 to the pressing station and aligns the pressing head 402 on the material handling mechanism 103 with the receiving hole of the powder forming fixture 105 (that is, the pressing head 402 is located directly above the receiving hole of the powder forming fixture 105 and coaxial with the receiving hole).

[0099] The control system controls the lifting and positioning mechanism 106 to lift again, causing the powder forming fixture 105 to rise a preset distance. This causes the powder in the receiving hole to be compressed and flattened between the fixed pressure head 402 and the rising mold base 302. After pressing, the control system controls the lifting and positioning mechanism 106 to descend completely, returning the powder forming fixture 105 to the conveyor line 107 and disengaging the lifting and positioning mechanism 106 from the powder forming fixture 105 (at this time, the fixture positioning pin of the lifting and positioning mechanism 106 disengages from the fixture positioning hole of the powder forming fixture 105). Finally, the control system controls the conveyor line 107 to transport the pre-pressed powder forming fixture 105 to the next station. Furthermore, it can also prepare to receive new fixtures and start a new cycle.

[0100] The thermal cell pressing apparatus and method provided in this application can be widely applied in automated production lines for thermal batteries, lithium batteries, or other electronic components that require powder pressing. By highly integrating and automating multiple functional modules such as feeding, sorting, feeding, and pressing, the automation level and production cycle of the production line are improved. The highly integrated single-station design reduces the equipment footprint and simplifies the structure compared to traditional multi-station production lines, thus reducing manufacturing costs and maintenance difficulty. The fully automated closed-loop process eliminates the cumulative errors of station transfer and repetitive positioning, improving the uniformity of powder thickness and the density consistency of the pre-pressed powder cake, thereby increasing the final product qualification rate. Finally, the application of passive or simplified mechanisms such as spring-assisted ejection (demolding spring) and magnetic reset (with magnetic push-pull plate) shortens the work cycle time, reduces energy consumption and mechanical failure rate, and enhances the robustness and production efficiency of the system. In addition, the modular design of this application makes equipment maintenance and upgrades more convenient and can adapt to the production needs of different product specifications.

After the push-pull plate (406) is disengaged from the pull-out plate (202), the control system controls the lifting and positioning mechanism (106) to descend, so that the feeding positioning hole (205) of the powder feeding mechanism (104) is disengaged from the receiving port positioning pin of the material handling mechanism (103) under the action of the descent of the lifting and positioning mechanism (106) and the elastic force of the demolding spring (405); The control system controls the movement of the slider of the movable slide (102), which drives the material handling mechanism (103) to move a preset distance away from the powder feeding mechanism (104); The control system controls the robotic arm to remove the powder feeding mechanism (104). The control system controls the slider of the moving slide (102) to move, driving the material handling mechanism (103) to move towards the powder forming fixture (105) until the pressure head (402) of the material handling mechanism (103) is directly above the receiving hole of the powder forming fixture (105) and coaxial with the receiving hole. The control system controls the lifting and positioning mechanism (106) to lift upward, which drives the powder forming fixture (105) to rise a preset distance, so that the powder material in the receiving hole is flattened under the pressure of the pressure head (402) and the pushing force of the lifting and positioning mechanism (106) on the powder forming fixture (105). The control system controls the lifting and positioning mechanism (106) to descend, which in turn drives the powder forming tool (105) to descend to the conveyor line (107). After the powder forming fixture (105) descends to the conveyor line (107), the control system controls the lifting and positioning mechanism (106) to continue descending, so that the fixture positioning pin of the lifting and positioning mechanism (106) disengages from the fixture positioning hole of the powder forming fixture (105). The control system controls the conveyor line (107) to transfer the powder forming fixture (105) to the next station.
