Description

Technical Field

[0001] This utility model relates to the field of microporous plate film tearing technology, specifically to a microporous plate support plate movement device for a film tearing machine. Background Technology

[0002] In experimental and industrial settings such as biological sample storage, high-throughput liquid processing, and drug synthesis, microplates serve as core containers. They must first be placed on the tray of a film-peeling machine, and then the microplates are moved by the motion device inside the film-peeling machine. The surface sealing film of the microplates is removed by the film-peeling machine, and then the microplates are transferred by external transfer equipment to subsequent tooling such as automatic pipettes, centrifuges, and ELISA readers to complete liquid transfer, separation, or detection operations.

[0003] Because the microplate itself is deep and has a high center of gravity, and there is often an angle difference between the discharge direction of the film-tearing machine (such as transverse conveying) and the feeding direction of the subsequent tooling (such as longitudinal feeding), it is necessary to not only complete the straight transfer after film tearing, but also to make precise angle conversion.

[0004] Currently, the industry's solutions for achieving microporous plate angle conversion still rely on independent rotary drive equipment. This involves adding an independent rotary device, such as an electric rotary table, to the pallet motion device of the film-tearing machine. This requires integrating a stepper motor, an angle sensor, and a dedicated control circuit. After the rotation angle is set by the program, it is mechanically connected to the linear conveyor mechanism to drive the microporous plate to rotate.

[0005] However, existing solutions for microplate motion devices are complicated by the independent drive equipment, resulting in a larger device size, more cumbersome assembly process, and the need to separately inspect the rotation and conveying systems during subsequent maintenance, further increasing maintenance costs. Utility Model Content

[0006] In view of this, the present invention provides a microperforated plate support motion device for a film tearing machine, which adopts a pure mechanical linkage method to realize the angle conversion of the microperforated plate, without the need for additional independent rotation drive equipment. This not only greatly simplifies the overall structure of the device and reduces the space occupied by the device, but also reduces manufacturing costs and subsequent maintenance costs.

[0007] To solve the above-mentioned technical problems, this utility model provides a microporous plate support moving device for a film-tearing machine, including a base and a mounting frame installed in the base. A linear sliding mechanism is provided in the base, and the mounting frame is connected to the linear sliding mechanism, enabling the linear sliding mechanism to drive the mounting frame to slide linearly. A protrusion is provided on the upper part of the mounting frame, and a bearing is installed in the protrusion. A rotating shaft is provided on the inner ring of the bearing, allowing the rotating shaft to rotate. A support plate is provided at the upper end of the rotating shaft for holding the microporous plate. The lower end of the rotating shaft passes through the bearing and extends into the mounting frame, and a gear is provided at the lower end of the rotating shaft. A guide is provided in the mounting frame, and a rack plate is slidably fitted in the mounting frame through the guide, so that the rack plate and the mounting frame are in sliding engagement, and the rack plate is meshed with the gear. A stop is also provided on an inner side wall of the base to block the movement of the rack plate. When the linear sliding mechanism drives the support plate... After the mounting frame and tray move linearly to drive the microporous plate through the film-tearing process, the mounting frame moves to the designated position. At this point, one end of the rack plate abuts against the stop and remains stationary due to the stop. However, because the rack plate slides with the mounting frame through the guide, the rack plate remains stationary while the mounting frame, shaft, gear, tray, and microporous plate on the tray can continue to move linearly. Since the gear and rack plate are meshed, the gear can drive the shaft to rotate around its own axis through meshing with the stationary rack plate. This causes the shaft to drive the tray and microporous plate to rotate synchronously, thus achieving the angle conversion of the microporous plate. Therefore, in the equipment for tearing film from microporous plates, pure mechanical meshing transmission replaces the existing rotating equipment, eliminating the need for an additional independent rotating module. This reduces equipment manufacturing and subsequent maintenance costs, simplifies the device structure, and reduces the space occupied by the equipment.

[0008] The guide component includes a guide plate, which is fixedly mounted on one end face of the mounting bracket near the stop. Two symmetrical insertion holes are formed on both sides of the guide plate surface, each containing a guide rod whose length is parallel to the linear movement direction of the mounting bracket. The guide component also includes a fixed bracket, with both ends of the guide rod fixedly mounted on the two inner side walls of the fixed bracket. A groove extending along the movement direction of the mounting bracket is formed on the upper surface of the fixed bracket. A gear is located within the groove and is in sliding engagement with it. A rack plate is mounted on one inner side wall of the groove and meshes with the gear. When the mounting bracket and the fixed bracket move to the designated position… After placement, one outer side wall of the fixed frame can first abut against the stop, causing the fixed frame, guide rod, and rack plate to stop moving. The mounting frame drives the gear to continue moving. At this time, the guide plate on the end face of the mounting frame slides along the surface of the guide rod, causing the gear to slide in the groove. Since the gear meshes with the rack plate, the gear achieves its own rotation through meshing transmission with the stationary rack plate, thereby driving the rotating shaft to rotate. Through the cooperation between the guide rod, the fixed frame, and the guide plate, the rack plate is guided, so that while the rack plate slides with the mounting frame, the rack plate and the gear can always maintain meshing.

[0009] A spring 304 is fitted onto the guide rod 303. One end of the spring 304 is fixedly connected to the side wall of the guide plate 205, and the other end is fixedly connected to an inner side wall of the fixed frame 300 facing the stop 500. In the initial assembly state, the spring is in a naturally extended state. When the mounting frame moves towards the stop under the drive of the linear drive mechanism, it simultaneously drives the fixed frame to move closer to the stop. When one end of the fixed frame abuts against the stop, it stops moving and remains stationary due to the blocking effect of the stop. The guide plate, which moves with the mounting frame, and the stationary inner wall of the fixed frame generate relative displacement, and the distance between them gradually decreases, thereby compressing the spring fitted onto the guide rod, causing the spring to gradually compress and deform until the mounting frame moves to the preset end position. When the microporous plate is removed by subsequent tooling and a new microporous plate is placed in, the linear drive mechanism starts in reverse. The mounting bracket is moved away from the stop, and the spring, which was originally compressed, gains room to rebound. Under the action of elastic restoring force, it applies a thrust to the inner wall of the mounting bracket facing the stop, thereby driving the rack plate fixed to the mounting bracket to reset synchronously. As the rack plate resets, the gear moves to the side of the slide groove away from the stop. At the same time, the rolling of the gear drives the rotating shaft to rotate in the opposite direction around its own axis. The support plate at the upper end of the rotating shaft rotates synchronously with the rotating shaft until the support plate returns to the initial horizontal angle (i.e., the preset angle when tearing the film), completing the reset action of the entire device and preparing for the next linear transport and angle conversion process of the microporous plate.

[0010] An adjusting plate is provided on the end face of the mounting bracket facing away from the stop, so that the adjusting plate and the guide plate are located on the two ends of the mounting bracket respectively. The surface of the adjusting plate also has insertion holes coaxial with the guide rods, and the guide rods pass through the insertion holes of the guide plate and the adjusting plate respectively and are fixed to the inner wall of the fixing bracket. A threaded hole is provided on the side wall of the fixing bracket away from the stop, and a bolt is fitted into the threaded hole. After the shank of the bolt is screwed through the threaded hole, its end abuts against the surface of the adjusting plate. When the bolt is screwed, causing it to push the adjusting plate, the mounting bracket and the adjusting plate are in a stationary state because the mounting bracket is controlled by a linear sliding mechanism. However, the fixing bracket, which is threaded with the bolt, will move through the bolt... As the plate is rotated away from the stop, it moves synchronously with the fixed frame. During this movement, the rack engages with the meshing gear, causing the gear to rotate. This, in turn, adjusts the rotation angle of the support plate and the microporous plate. Before the microporous plate is moved by the linear sliding mechanism, the initial angle of the microporous plate before the film is to be peeled can be adjusted by rotating the bolts on the fixed frame. After the fixed frame abuts the stop, the final angle of the microporous plate after rotation will also be different, provided that the moving distance of the mounting frame remains constant. This invention solves the problem of the inability to freely adjust the angle of the microporous plate before and after film peeling in the prior art using adjustable bolts on the fixed frame.

[0011] As shown in Figures 1 and 2, the linear sliding mechanism includes a guide rail, which is fixedly installed along the transport direction of the micro-perforated plate (i.e., the direction in which the mounting bracket moves towards the stop). The guide rail is elongated and relatively fixed to the base, providing a guiding reference for the linear movement of the mounting bracket. A slider is slidably fitted on the guide rail, and the bottom of the mounting bracket is fixedly connected to the slider, allowing the mounting bracket to slide synchronously with the slider along the extension direction of the guide rail. The driving component in the linear sliding mechanism is installed inside the base, and its output end is connected to the mounting bracket to provide power for the linear movement of the mounting bracket.

[0012] Specifically, the driving component includes a motor, which is located on the side of one end of the guide rail. The motor body is fixed inside the base by a frame, while a support frame is provided on the side of the other end of the guide rail. A bearing is installed on the support frame through a bearing seat, and a driven wheel is installed on the inner ring of the bearing. A driving wheel is installed on the rotating shaft of the motor. Both the driving wheel and the driven wheel are synchronous pulleys, and a synchronous belt is used for transmission between them.

[0013] The mounting bracket has a clamping element on the side facing the synchronous belt. This clamping element holds the lower half of the synchronous belt (i.e., the lower belt section between the driving pulley and the driven pulley). The clamping element forms a rigid linkage with the synchronous belt through mechanical clamping or meshing, ensuring that the synchronous belt can drive the mounting bracket to move synchronously when it moves. When the device starts the transport program, the motor is energized and rotates, driving the driving pulley on the output shaft to rotate synchronously. The driving pulley, through the meshing of its teeth with the synchronous belt, drives the synchronous belt to move along a circular track. The side of the synchronous belt away from the motor drives the driven pulley to rotate in the same direction as the driving pulley, forming a closed-loop transmission. When the synchronous belt moves... Its lower part, through the fixing action of the clamping parts, drives the mounting frame to move along the guide rail towards or away from the stop. When the motor rotates forward, the synchronous belt drives the mounting frame to move towards the stop (transporting the micro-perforated plate); when the motor rotates in reverse, the synchronous belt drives the mounting frame to return to the initial position. The synchronous belt is driven by the meshing of teeth, with no relative slippage, ensuring that the moving distance of the mounting frame is in strict proportion to the rotation angle of the motor. Compared with transmission methods such as lead screws, gears and racks, synchronous belt drives do not require a complex lubrication system, and have fewer parts and lower assembly difficulty, which can reduce the manufacturing and maintenance costs of the device.

[0014] Furthermore, the clamping component includes a pull plate fixedly mounted on the mounting frame. The pull plate has an L-shaped structure, with one plane of the pull plate fixed to the side wall of the mounting frame. It also includes a pressure plate, which is attached to the other plane of the pull plate. Multiple through holes are provided on the vertical planes of the two components. Double-ended bolts are inserted into the through holes of the pull plate and the pressure plate that correspond to each other axially, and nuts are screwed onto both ends of the double-ended bolts.

[0015] During assembly, the lower half of the synchronous belt is placed between the pull plate and the pressure plate, aligning the teeth on the lower wall of the pressure plate with the teeth of the synchronous belt. Then, the upper bolts are tightened, and the axial force of the bolts presses the pressure plate towards the pull plate. The teeth embed into the grooves of the synchronous belt, forming a dual fixation of mechanical meshing and clamping force. This prevents relative slippage between the synchronous belt and the clamping components, while the clamping force ensures stable meshing. When the synchronous belt moves under the drive of the motor, the teeth of the synchronous belt mesh with the teeth of the pressure plate, causing the pressure plate to move synchronously with the synchronous belt. Since the pressure plate and pull plate are fixed together by bolts, the pull plate moves synchronously with the pressure plate, which in turn drives the mounting bracket fixed to the pull plate to move linearly along the guide rail. This achieves power transmission from the synchronous belt to the mounting bracket. The combination of rigid clamping and flexible transmission avoids vibration transmission caused by rigid connections and ensures the stability of power transmission, further improving the smooth operation of the entire linear sliding mechanism and providing a reliable power foundation for the precise transport and angle conversion of the micro-perforated plate.

[0016] The stop includes a baffle plate, which is fixedly installed on one end of the guide rail near the drive component. The surface of the baffle plate is perpendicular to the length direction of the guide rail and is rigidly connected to the base or the fixed seat of the guide rail by bolts to ensure that it does not shift when impacted by the fixed frame. A stop block is provided on the side wall of the baffle plate facing the fixed frame, corresponding to the position of the fixed frame's movement trajectory. When the mounting frame moves along the guide rail towards the stop component under the drive component, the fixed frame moves synchronously with the mounting frame, gradually approaching the stop block on the baffle plate. The stop block generates a reverse resistance force on the fixed frame. Since the baffle plate is fixed to the base, the fixed frame stops moving and remains stationary under the constraint of the stop block. After the fixed frame stops, the mounting frame continues to move under the action of the drive component. At this time, the rack plate on the fixed frame remains stationary with the fixed frame, while the gear on the mounting frame continues to move with the mounting frame. The meshing action of the gear and the stationary rack plate... The gear starts to rotate, which in turn drives the rotating shaft and the support plate to rotate, realizing the angle conversion of the micro-perforated plate. When the mounting bracket completes the angle conversion and begins to reset, the fixed bracket moves away from the baffle under the push of the spring and the drive of the adjusting plate, disengaging from the stop block and returning to the initial position to wait for the next trigger. The design of this stop component is consistent with the pure mechanical drive concept of the whole device. It achieves precise triggering of angle conversion through a simple mechanical structure, without the need for additional control programs or sensing elements, further simplifying the device structure, reducing the overall cost, and ensuring the stability and consistency of the angle conversion action.

[0017] Furthermore, a threaded hole adapted to a bolt is provided on the surface of the baffle corresponding to the center position of the moving trajectory of the fixed frame. The axis of the threaded hole is parallel to the moving direction of the mounting frame. A bolt is threaded into the threaded hole, and a stop block is fixedly installed at the end of the bolt through the threaded engagement. Adjusting the bolt allows it to move along its own axis, thereby causing the stop block to change position synchronously. When it is necessary to adjust the final rotation angle of the micro-orifice plate, the bolt on the baffle is turned clockwise with a tool. The bolt causes the stop block to move closer to the fixed frame, shortening the distance between the stop block and the initial position of the fixed frame. When the distance between the stop block and the fixed frame decreases, the fixed frame can contact the stop block and stop after the mounting frame has moved a short distance. At this time, the meshing stroke of the gear and rack plate is shortened, reducing the gear rotation angle. Thus, through the threaded feed characteristics of the bolt, the position of the stop block can be continuously adjusted, and the rotation angle of the corresponding micro-orifice plate can be flexibly set within a large range to adapt to the angle requirements of different subsequent tooling. This allows the device to maintain the advantages of pure mechanical drive while possessing stronger versatility and adaptability. With a simple threaded adjustment structure, multi-angle adaptation can be achieved without the need for additional angle drive components. This simplifies the structure, reduces costs, and fully demonstrates the rationality and practicality of the device's design.

[0018] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0019] 1. When this utility model is used, the angle conversion of the micro-perforated plate is achieved by a pure mechanical linkage method, without the need for an additional independent rotation drive device. This not only greatly simplifies the overall structure of the device and reduces the space occupied by the device, but also reduces manufacturing costs and subsequent maintenance costs.

[0020] 2. When in use, this utility model has a two-way angle adjustment capability. The initial angle of the microplate to be transferred can be flexibly adjusted by turning the adjusting bolt on the fixing frame. Turning the adjusting bolt on the stop can accurately set the final angle of the microplate after transfer. It can adapt to the size requirements of microplates of different specifications and various subsequent tooling, such as the feeding angle requirements of testing equipment, effectively improving the adaptability and flexibility of the device.

[0021] 3. When this utility model is used, the linear transportation and angle conversion functions of the micro-perforated plate are integrated into one, eliminating the need to start different drive modules in stages. From the loading and linear transportation of the micro-perforated plate to the automatic completion of angle conversion, unloading and equipment reset, a continuous operation loop is formed, reducing intermediate operation links and waiting time, and significantly improving the overall operation efficiency of micro-perforated plate transfer.

[0022] 4. When this utility model is used, the gear and rack meshing transmission ensures the accuracy of angle conversion, the guide rail slider structure ensures straight-line transportation without deviation, and the elastic stop and spring buffer design reduces rigid collisions between components. The synergistic effect of multiple mechanical structures not only ensures the accuracy of micro-perforated plate transportation and angle conversion, but also extends the service life of components, ensuring the long-term stability and reliability of the equipment.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0031] A microporous plate support moving device for a film peeling machine, such as Figure 1 , Figure 2 and Figure 3As shown: It includes a base 100 and a mounting bracket 200 installed in the base 100. The base 100 is provided with a linear sliding mechanism, and the mounting bracket 200 is connected to the linear sliding mechanism so that the linear sliding mechanism can drive the mounting bracket 200 to slide linearly.

[0032] The mounting bracket 200 has a protrusion on its upper part, and a bearing 201 is installed in the protrusion. The inner ring of the bearing 201 is provided with a rotating shaft 202, so that the rotating shaft 202 can rotate through the bearing 201.

[0033] The upper end of the rotating shaft 202 is provided with a support plate 204, which is used to hold the microporous plate. The lower end of the rotating shaft 202 passes through the bearing 201 and extends into the mounting bracket 200. The lower end of the rotating shaft 202 is provided with a gear 203. The mounting bracket 200 is provided with a guide, and a rack plate 302 is slidably fitted in the mounting bracket 200 through the guide, so that the rack plate 302 and the mounting bracket 200 are in sliding fit, and the rack plate 302 and the gear 203 are meshed.

[0034] A stop 500 is also provided on one inner side wall of the base 100, which is used to block the movement of the rack plate 302;

[0035] When the linear sliding mechanism drives the mounting bracket 200 and the support plate 204 to move linearly to move the microporous plate through the film-tearing process, the mounting bracket 200 will move to the designated position. At this time, one end of the rack plate 302 can abut against the stop member 500 and remain stationary due to the obstruction of the stop member 500. However, since the rack plate 302 is in sliding engagement with the mounting bracket 200 through the guide member, the rack plate 302 remains stationary while the mounting bracket 200, the rotating shaft 202, the gear 203, the support plate 204, and the microporous plate on the support plate 204 can continue to move linearly. At this time, since the gear 203 and the rack plate 302 are meshed, the rack plate 302 remains stationary, while the gear... The linear movement of gear 203 enables gear 203 to drive the rotating shaft 202 to rotate around its own axis through meshing with the stationary rack plate 302. This causes the rotating shaft 202 to drive the support plate 204 and the microporous plate to rotate synchronously, thereby realizing the angle conversion of the microporous plate. Once the rotation reaches the specified angle, the sliding of the mounting bracket 200 is stopped by the linear drive mechanism. This allows the equipment for tearing film from microporous plates to replace the existing rotating equipment with pure mechanical meshing transmission, eliminating the need for an additional independent rotating module. This reduces equipment manufacturing and subsequent maintenance costs, simplifies the device structure, and reduces the space occupied by the equipment.

[0036] Specifically, the mounting bracket 200 is designed as a frame structure, and the end faces of the two openings of the mounting bracket 200 correspond to the two ends of the sliding direction, respectively. The guide component includes a guide plate 205, which is fixedly installed on one end face of the mounting bracket 200 near the stop component 500.

[0037] Two insertion holes are symmetrically opened on both sides of the surface of the guide plate 205. A guide rod 303 is inserted into each insertion hole, and the length direction of the guide rod 303 is parallel to the linear movement direction of the mounting bracket 200.

[0038] The guide also includes a fixed frame 300. The two ends of the guide rod 303 are fixedly mounted on the two inner side walls of the fixed frame 300. The upper surface of the fixed frame 300 is provided with a sliding groove 301 extending along the moving direction of the mounting frame 200. The gear 203 is located in the sliding groove 301 and is in sliding engagement with the sliding groove 301. The rack plate 302 is mounted on one inner side wall of the sliding groove 301 and is engaged with the gear 203.

[0039] When the mounting bracket 200 and the fixed bracket 300 move to the designated position, one outer side wall of the fixed bracket 300 can first abut against the stop member 500, so that the fixed bracket 300, the guide rod 303 and the rack plate 302 all stop moving. The mounting bracket 200 drives the gear 203 to continue moving. At this time, the guide plate 205 on the end face of the mounting bracket 200 slides along the surface of the guide rod 303, so that the gear 203 slides in the slide groove 301. Since the gear 203 meshes with the rack plate 302, the gear 203 achieves its own rotation through meshing transmission with the stationary rack plate 302, thereby driving the rotating shaft 202 to rotate. Through the cooperation between the guide rod 303, the fixed bracket 300 and the guide plate 205, the rack plate 302 is guided, so that while the rack plate 302 slides with the mounting bracket 200, the rack plate 302 can always maintain meshing with the gear 203.

[0040] Specifically, each guide rod 303 is fitted with a compression spring 304. One end of the spring 304 is fixedly connected to the side wall of the guide plate 205 facing the fixed frame 300 by welding, and the other end is also fixedly connected to the inner side wall of the fixed frame 300 facing the stop 500 by welding. When the microporous plate is peeled off, the spring 304 is in a natural extension and contraction state with no pre-compression, and only serves to connect the guide plate 205 and the fixed frame 300.

[0041] When the angle of the microplate needs to be adjusted, the mounting bracket 200 moves towards the stop 500 under the drive of the linear drive mechanism, simultaneously moving the fixing bracket 300 closer to the stop 500; when the end of the fixing bracket 300 away from the mounting bracket 200 abuts against the stop 500, the fixing bracket 300 stops moving and remains stationary due to the blocking effect of the stop 500.

[0042] At this time, the linear drive mechanism continues to drive the mounting frame 200 and the guide plate 205 fixed to the mounting frame 200 to move towards the stop 500. The guide plate 205 moving with the mounting frame 200 generates relative displacement with the inner wall of the stationary fixed frame 300, and the distance between the two gradually decreases, thereby squeezing the spring 304 sleeved on the guide rod 303, causing the spring 304 to gradually compress and deform until the mounting frame 200 moves to the preset end position.

[0043] When the microplate is removed by the subsequent tooling and a new microplate is placed in, the linear drive mechanism starts in reverse, driving the mounting bracket 200 to reset in the direction away from the stop 500. When the mounting bracket 200 moves, it simultaneously drives the guide plate 205 to move in the direction away from the stop 500. The spring 304, which was originally in a compressed state, gains a rebound space. Under the action of elastic restoring force, it applies a pushing force to the inner wall of the fixed bracket 300 toward the stop 500, thereby driving the rack plate 302 fixed to the fixed bracket 300 to reset synchronously.

[0044] As the rack plate 302 resets, the gear 203, which is meshed with the rack plate 302, rolls along the tooth surface of the rack plate 302 under the action of meshing transmission, eventually moving the gear 203 to the side of the slide groove 301 away from the stop 500. At the same time, the rolling of the gear 203 drives the rotating shaft 202 to rotate in the opposite direction around its own axis. The support plate 204 at the upper end of the rotating shaft 202 rotates synchronously with the rotating shaft 202 until the support plate 204 returns to the initial horizontal angle (i.e. the preset angle when tearing the film), completing the reset action of the entire device and preparing for the next film tearing and angle conversion process of the microporous plate.

[0045] Furthermore, an adjustment plate 206 is provided on the end face of the mounting bracket 200 facing away from the stop member 500, so that the adjustment plate 206 and the guide plate 205 are respectively located on the two end faces of the mounting bracket 200. The surface of the adjustment plate 206 is also provided with a hole corresponding to the guide rod 303 coaxially, and the guide rod 303 passes through the holes of the guide plate 205 and the adjustment plate 206 respectively and is fixed on the inner wall surface of the fixing bracket 300.

[0046] The fixing frame 300 has a bolt threaded through a threaded hole. The end of the bolt abuts against the surface of the adjusting plate 206. By turning the bolt, the distance between the inner wall of the fixing frame 300 and the adjusting plate 206 can be changed, thereby adjusting the initial horizontal position of the fixing frame 300.

[0047] Specifically, a threaded hole is provided on the side wall of the fixing bracket 300 away from the stop member 500, and a bolt is installed in the threaded hole. After the shank of the bolt is screwed through the threaded hole, its end abuts against the surface of the adjusting plate 206;

[0048] When the fixed frame 300 contacts the stop 500 and comes to a stop, the mounting frame 200 and the adjusting plate 206 continue to move linearly by being driven by the linear sliding mechanism. At this time, the bolt ends on the side wall of the fixed frame 300 will disengage from the adjusting plate 206 and gradually move away to form a gap.

[0049] When the mounting bracket 200 resets and moves away from the stop 500, the spring 304 gradually rebounds until the adjusting plate 206 moves to re-abut against the bolt end. When the adjusting plate 206 continues to move, it drives the fixing bracket 300 to move synchronously through the bolt. At this time, the rebound thrust of the spring 304 on the fixing bracket 300 is opposite to the pulling force of the adjusting plate 206 on the fixing bracket 300 through the bolt, forming a dynamic balance. This ensures that the fixing bracket 300 and the mounting bracket 200 always move synchronously, avoiding structural jamming caused by relative displacement.

[0050] When the bolt is tightened, causing it to push the adjusting plate 206, the mounting bracket 200 and the adjusting plate 206 remain stationary due to the linear sliding mechanism controlling the mounting bracket 200. However, the fixing bracket 300, which is threaded with the bolt, moves away from the stop 500 as the bolt is tightened. At this time, the rack plate 302 moves synchronously with the fixing bracket 300, engaging with the meshing gear 203 to drive the gear 203 to rotate, thereby realizing the movement of the support plate 204 and the micro-hole. The rotation angle of the plate allows the initial angle of the microporous plate to be peeled off to be adjusted by tightening the bolts on the fixing frame 300 before the microporous plate is moved by the linear sliding mechanism. Furthermore, after the fixing frame 300 abuts against the stop 500, the final angle of the microporous plate after rotation will also be different, provided that the moving distance of the mounting frame 200 remains unchanged. This invention solves the problem of the inability to freely adjust the angle of the microporous plate before and after peeling off the film in the prior art by means of adjustable bolts on the fixing frame 300.

[0051] according to Figure 2 , Figure 4 and Figure 5 As shown, the linear sliding mechanism includes a guide rail 400, which is fixedly mounted along the transport direction of the micro-perforated plate (i.e., the direction in which the mounting frame 200 moves towards the stop 500). The guide rail 400 is elongated and relatively fixed to the base 100, providing a guiding reference for the linear movement of the mounting frame 200. A slider 401 is slidably fitted on the guide rail 400, and the bottom of the mounting frame 200 is fixedly connected to the slider 401, allowing the mounting frame 200 to slide synchronously with the slider 401 along the extension direction of the guide rail 400. The driving component in the linear sliding mechanism is installed inside the base 100, and its output end is connected to the mounting frame 200 to provide power for the linear movement of the mounting frame 200.

[0052] Specifically, the driving component includes a motor 600, which is located on the side of one end of the guide rail 400. The motor 600 is fixed inside the base 100 by a frame. A support frame 604 is provided on the side of the other end of the guide rail 400. A bearing is mounted on the support frame 604 through a bearing seat, and a driven wheel 602 is mounted on the inner ring of the bearing. A driving wheel 601 is mounted on the rotating shaft of the motor 600. Both the driving wheel 601 and the driven wheel 602 are synchronous pulleys, and a synchronous belt 603 is used for transmission between them.

[0053] The mounting bracket 200 has a clamping member on the side facing the synchronous belt 603. This clamping member holds the lower half of the synchronous belt 603 (i.e., the lower belt section between the driving pulley 601 and the driven pulley 602). The clamping member forms a rigid linkage with the synchronous belt 603 through mechanical clamping or engagement, ensuring that the synchronous belt 603 can drive the mounting bracket 200 to move synchronously. When the device starts the transport program, the motor 600 is energized and rotates, driving the driving pulley 601 on the output shaft to rotate synchronously. The driving pulley 601, through the meshing of its teeth with the synchronous belt 603, drives the synchronous belt 603 to move along a circular track. The side of the synchronous belt 603 away from the motor 600 drives the driven pulley 602 to rotate in the same direction as the driving pulley 601, forming a closed-loop transmission. During operation, the lower part of the mounting bracket 200 moves along the guide rail 400 towards or away from the stop 500 through the fixing action of the clamping member. When the motor 600 rotates forward, the synchronous belt 603 moves the mounting bracket 200 towards the stop 500 (transporting the micro-perforated plate). When the motor 600 rotates in reverse, the synchronous belt 603 moves the mounting bracket 200 back to its initial position. The synchronous belt 603 is driven by the meshing of teeth, with no relative slippage, ensuring that the moving distance of the mounting bracket 200 and the rotation angle of the motor 600 are in strict proportion. Compared with transmission methods such as lead screws, gears, and racks, the synchronous belt 603 transmission does not require a complex lubrication system, and has fewer parts and lower assembly difficulty, which can reduce the manufacturing and maintenance costs of the device.

[0054] Furthermore, the clamping component includes a pull plate 700 fixedly mounted on the mounting bracket 200. The pull plate 700 has an L-shaped structure, and one plane of the pull plate 700 is fixed to the side wall of the mounting bracket 200. It also includes a pressure plate 701, which fits against the other plane of the pull plate 700. Multiple through holes are provided on the vertical planes of the two components. Double-ended bolts are inserted into the through holes of the pull plate 700 and the pressure plate 701 that correspond axially, and nuts are screwed onto both ends of the double-ended bolts.

[0055] During assembly, the lower half of the synchronous belt 603 is placed between the pull plate 700 and the pressure plate 701, aligning the teeth of the lower wall of the pressure plate 701 with the teeth of the synchronous belt 603. Then, the upper bolts are tightened, and the axial force of the bolts presses the pressure plate 701 against the pull plate 700, causing the teeth to engage in the grooves of the synchronous belt 603, forming a combination of mechanical engagement and clamping force. The double fixing prevents relative slippage between the synchronous belt 603 and the clamping parts, while the clamping force ensures stable engagement. When the synchronous belt 603 moves under the drive of the motor 600, the teeth of the synchronous belt 603 engage with the teeth of the pressure plate 701, causing the pressure plate 701 to move synchronously with the synchronous belt 603. Since the pressure plate 701 and the pull plate 700 are fixed together by bolts, the pull plate 700 moves synchronously with the pressure plate 701, thereby driving the mounting bracket 200 fixed to the pull plate 700 to move linearly along the guide rail 400, realizing the power transmission from the synchronous belt 603 to the mounting bracket 200.

[0056] If it is necessary to replace the timing belt 603 or adjust the position of the mounting bracket 200, simply loosen the locking bolts and release the clamping of the timing belt 603 by the pressure plate 701. The timing belt 603 can then be removed from the clamping parts. After the operation is completed, tighten the bolts again to restore fixation. No other parts need to be disassembled. The combination of rigid clamping and flexible transmission avoids the vibration transmission caused by rigid connection and ensures the stability of power transmission, further improving the smooth operation of the entire linear sliding mechanism and providing a reliable power foundation for the precise transportation and angle conversion of the micro-perforated plate.

[0057] according to Figure 2 and Figure 4 As shown, the stop member 500 includes a baffle 501 fixed to one end of the guide rail 400. A stop block 502 is provided on one side wall of the baffle 501 facing the fixing frame 300. The fixing frame 300 can abut against the stop block 502 to achieve a stationary position.

[0058] Specifically, the baffle 501 is fixedly installed at one end of the guide rail 400 near the driving component (i.e., the end point of the moving trajectory of the mounting bracket 200). The surface of the baffle 501 is perpendicular to the length direction of the guide rail 400 and is rigidly connected to the base 100 or the fixing seat of the guide rail 400 by bolts, ensuring that it does not shift when impacted by the fixing bracket 300. On the side wall of the baffle 501 facing the fixing bracket 300, a stop block 502 is provided corresponding to the position of the moving trajectory of the fixing bracket 300.

[0059] When the mounting bracket 200 moves along the guide rail 400 towards the stop member 500 under the drive of the driving component, the fixed bracket 300 moves synchronously with the mounting bracket 200, gradually approaching the stop block 502 on the baffle 501. The stop block 502 generates a reverse blocking force on the fixed bracket 300. Since the baffle 501 is fixed to the base 100, the fixed bracket 300 stops moving and remains stationary under the constraint of the stop block 502. After the fixed bracket 300 comes to a stop, the mounting bracket 200 continues to move under the action of the driving component. At this time, the rack plate 302 on the fixed bracket 300 remains stationary with the fixed bracket 300. The gear 203 on the mounting bracket 200 continues to move with the mounting bracket 200. The meshing action of the gear 203 with the stationary rack plate 302 causes the gear 203 to start rotating, which in turn drives the rotating shaft 202 and the support plate 204 to rotate, realizing the angle conversion of the micro-perforated plate. When the mounting bracket 200 completes the angle conversion and begins to reset, the fixed bracket 300 moves away from the baffle 501 under the push of the spring 304 and the drive of the adjusting plate 206, disengaging from the stop block 502 and returning to the initial position to wait for the next trigger. The design of the stop 500 is consistent with the overall "pure mechanical drive" concept of the device. It achieves precise triggering of angle conversion through a simple mechanical structure, without the need for additional control programs or sensing elements, further simplifying the device structure, reducing the overall cost, and ensuring the stability and consistency of the angle conversion action.

[0060] Furthermore, the surface of the baffle 501 is provided with a threaded hole that matches the bolt at the center position of the moving trajectory of the fixed frame 300. The axis of the threaded hole is parallel to the moving direction of the mounting frame 200. The bolt is threaded in the threaded hole. The stop block 502 is fixedly installed at the end of the bolt through the threaded engagement. Adjusting the bolt can move it along its own axis, thereby driving the stop block 502 to change its position synchronously.

[0061] When the final rotation angle of the microplate needs to be adjusted, when the bolt on the baffle 501 is turned clockwise with a tool, the bolt causes the stop 502 to move closer to the fixed frame 300, shortening the distance between the stop 502 and the initial position of the fixed frame 300; when turned counterclockwise, the stop 502 moves away from the fixed frame 300, increasing the initial distance between the two.

[0062] Furthermore, the change in the position of the stop block 502 directly affects the timing of the stationary position of the fixed frame 300. When the distance between the stop block 502 and the fixed frame 300 decreases, the fixed frame 300 can contact the stop block 502 and stop after the mounting frame 200 moves a short distance. At this time, the meshing stroke of the gear 203 and the rack plate 302 is shortened. However, when the distance between the stop block 502 and the fixed frame 300 increases, the fixed frame 300 needs to move a longer distance with the mounting frame 200 before it stops, and the meshing stroke is extended.

[0063] Since the meshing transmission ratio between gear 203 and rack plate 302 is fixed, the change in meshing stroke directly leads to the change in the rotation angle of gear 203. When the stroke is shortened, the rotation angle of gear 203 decreases; when the stroke is extended, the rotation angle increases, ultimately achieving precise adjustment of the rotation angle of the microporous plate.

[0064] By utilizing the threaded feed characteristics of the bolt, the position of the stop 502 can be continuously adjusted, allowing for flexible setting of the rotation angle of the corresponding micro-orifice plate within a wide range. This adapts to the angle requirements of different subsequent tooling, and while maintaining the advantage of "purely mechanical drive," the device also possesses greater versatility and adaptability. Through a simple threaded adjustment structure, multi-angle adaptation can be achieved without the need for additional angle drive components, simplifying the structure and reducing costs, fully demonstrating the rationality and practicality of the device's design.

[0065] How to use this utility model:

[0066] First, it needs to be clarified that this utility model relates to a microporous plate moving mechanism, mainly used in the film-tearing equipment of a film-tearing machine. Here it needs to be clarified that the base 100 is a mechanism in the film-tearing machine. Since the film-tearing component in the film-tearing machine is a device in the prior art, and some existing film-tearing machines are equipped with a moving mechanism for the perforated plate, since the film-tearing component is not the innovation of this utility model, its position is not limited here, nor is its structure described in detail. Only the usage method and installation position of the moving mechanism are described in detail.

[0067] In the initial state, the equipment is in a stopped state. The staff first adjusts the initial angle of the support plate 204 by turning the bolts on the fixing bracket 300 according to the specifications of the micro-perforated plate to be processed and the subsequent tooling angle requirements, and turns the bolts on the stop 500 to set the final rotation angle of the micro-perforated plate.

[0068] When the microporous plate to be peeled is placed on the tray 204 and the peeling operation is ready, the mounting frame 200 and the tray 204 are located on the side of the guide rail 400 away from the stop 502, and the motor 600 is started. The synchronous belt 603 is driven by the driving wheel 601 and the driven wheel 602. The synchronous belt 603, with the help of the teeth meshing and clamping action of the clamping member, drives the mounting frame 200 to move along the guide rail 400 towards the stop 502. During the movement, the microporous plate undergoes the peeling operation of the peeling assembly. Finally, the fixing frame 300 abuts against the stop 502 of the stop member 500 and comes to a stop, entering the angle conversion stage. The mounting frame 200 continues to move under the drive of the synchronous belt 603. The guide plate 205 moves with the mounting frame 200, compressing the spring 304 on the guide rod 303. At the same time, the gear 20... 3. Engages with the stationary rack plate 302 to drive the support plate 204 and the micro-perforated plate to rotate to the preset final angle. After the micro-perforated plate is removed by the subsequent automated tooling, the motor 600 of the drive component reverses, the synchronous belt 603 drives the mounting frame 200 to reset, the spring 304 rebounds and pushes the fixed frame 300 to move with the guide rod 303, the adjusting plate 206 abuts against the adjusting bolt on the fixed frame 300 and drives the fixed frame 300 to continue moving, the gear 203 engages with the rack plate 302 in the opposite direction to make the support plate 204 return to the initial angle, and finally the mounting frame 200 and all components are reset, completing one micro-perforated plate transfer cycle. The whole process relies on pure mechanical structure linkage, without the need for additional independent rotation modules, thereby reducing equipment manufacturing and subsequent maintenance costs, simplifying the device structure and reducing the space occupied by the equipment.

[0069] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
