Abstract
Description
Technical Field
[0001] This application belongs to the field of automated assembly equipment for cleaning tools, and particularly relates to a positioning device for assembling desqueezing parts. Background Technology
[0002] In daily life, mops and other cleaning tools are used to clean dirty floors, windows, walls, and other surfaces. To improve cleaning efficiency and effectiveness, existing technologies utilize wringer racks to squeeze water out of the wiping material on the mop during the washing process. Wringer racks are typically mounted on the mop body or in the mop washing tub. A wringer rack generally consists of a wringing component and a housing for holding the component. During manufacturing, operators usually assemble the wringing component onto the housing. Existing designs propose automated assembly methods to ensure efficiency. However, in automated production, the wringing component typically needs to be placed on a positioning block on a dividing plate, allowing the rack to be moved to different workstations during plate rotation. However, in existing designs, the wringing component, when placed on the positioning block, is easily thrown off during plate rotation. Utility Model Content
[0003] The problem to be solved by this invention is to provide a positioning device for assembling dewatering parts, so as to achieve convenient and stable positioning of the dewatering parts on the positioning block.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this invention is: a positioning device for assembling dewatering parts, comprising:
[0005] The positioning block is provided with a bearing groove and a negative pressure hole located at the bottom of the bearing groove;
[0006] A pneumatic assembly, including a cylinder and a vent pipe, the vent pipe connecting the cylinder and the lower part of the negative pressure port;
[0007] The bottom shape of the bearing groove is adapted to the water-squeezing component to be assembled. When the water-squeezing component enters the bearing groove, the negative pressure generated by the cylinder at the negative pressure hole will adsorb the water-squeezing component into the bearing groove.
[0008] In some embodiments, the dewatering element is cylindrical, and the radial dimension of the negative pressure hole is smaller than the diameter of the dewatering element.
[0009] In some embodiments, the negative pressure holes include a plurality of holes, which are arranged along the length of the bearing groove.
[0010] In some embodiments, there are three negative pressure holes, with at least two located at both ends of the bearing groove.
[0011] In some embodiments, the length of the bearing groove is less than the length of the dewatering element.
[0012] In some embodiments, the bearing grooves include several that are arranged in parallel.
[0013] In some embodiments, the negative pressure holes at the bottom of several of the bearing grooves are connected to the same cylinder.
[0014] In some embodiments, a pusher assembly is also included, the pusher assembly having an end face perpendicular to the length direction of the bearing groove on the side facing the positioning block, the pusher assembly being able to translate along the length direction of the bearing groove to simultaneously push several of the water-squeezing parts into several of the bearing grooves.
[0015] In some embodiments, the push plate assembly includes a plurality of push rods and a plate body, wherein the push rods are disposed on the side of the plate body facing the positioning block, and the ends of the plurality of push rods facing the positioning block are flush.
[0016] In some implementations, it is used in dewatering rack assembly equipment.
[0017] The beneficial effects of this application are: by setting a negative pressure hole at the bottom of the bearing groove of the positioning block, it is ensured that the water squeezing part can be adsorbed in the bearing groove when it enters the bearing groove, thereby preventing the water squeezing part from being thrown out or causing displacement deviation when the bearing groove moves, which would result in inaccurate assembly.

[0044] This application is described below with reference to the accompanying drawings and specific embodiments:
[0045] This dewatering rack assembly equipment is built based on the principles of ring indexing and multi-station collaboration, such as... Figure 1 As shown, it mainly consists of a base 100, an indexing plate 200, a feeding mechanism 300, a transfer mechanism 400, a pressing mechanism 500, a discharging mechanism 600, and a control system.
[0046] The machine base 100 is equipped with a circularly distributed loading station, transfer station, pressing station, and unloading station, forming a continuous production line. The indexing plate 200 is rotatably mounted in the center of the machine base 100. Figure 2As shown, multiple positioning blocks 201 are evenly distributed on the disc surface, each positioning block 201 corresponding to a workstation. The control system is electrically connected to other actuation systems. When the control system drives the indexing disc 200 to rotate intermittently via the control motor, the positioning blocks 201 sequentially transport the dewatering parts 10 to be assembled to each workstation for corresponding operations. Figure 3 As shown, the feeding mechanism 300 includes a hopper 301 and a pusher assembly 302. The hopper 301 adopts a gravity-feed structure, which can automatically sort and convey the dewatering parts 10 to the pushing position of the pusher assembly 302. The pusher assembly 302 is driven by a control system through a pneumatic component 800 or a servo motor. When the positioning block 201 rotates to the feeding station, the pusher assembly 302 smoothly pushes the dewatering parts 10 onto the positioning block 201 with a preset stroke. This structure achieves fully automatic feeding of the dewatering parts 10, avoiding positioning deviations that may be caused by manual intervention, and improving production efficiency and consistency. Figure 4 As shown, the transplanting mechanism 400 adopts a combination structure of multiple servo (or pneumatic) slides and robotic gripper devices, which can quickly position itself in the YZ plane. When the positioning block 201 rotates to the transplanting station, the control system drives the gripper device through the pneumatic component 800 to precisely grasp the squeezing rack housing 20 and move it onto the positioning block 201 according to a predetermined trajectory. Figure 5 , Figure 6 As shown, the mounting groove 21 on the lower side of the housing is aligned with the water-squeezing member 10. And as... Figure 7 As shown, the pressing plate 501 of the pressing mechanism 500 adopts a pneumatic and spring-loaded buffer structure. When the indexing plate 200 rotates to the pressing position, the control system drives the pressing plate 501 through the pneumatic component 800 to press down the housing 20 with constant pressure, so that the dewatering component 10 is fully embedded in the mounting groove 21. This pressure control method can ensure assembly strength and prevent deformation of parts caused by overpressure. At the same time, the lower part of the pressing plate 501 is shaped to match the upper shape of the dewatering frame housing 20, thereby avoiding the dewatering frame housing 20 from shifting due to inaccurate positioning during the pressing process, which could cause the product to be damaged by squeezing. Similar to the above-mentioned transfer mechanism 400, as... Figure 8 As shown, the discharge mechanism 600 also adopts a combination structure of multiple slides and robotic gripping devices, which can be quickly positioned in the YZ plane. When the assembled dewatering rack arrives at the unloading station, the gripping device accurately grabs the dewatering rack housing 20 assembled with the dewatering component 10 and moves it out of the indexing plate 200 according to the predetermined trajectory. Then it can be placed on the conveyor belt or allowed to fall naturally into the collection box at the predetermined position.
[0047] Its control system is generally a PLC control system in industrial production, which can be programmed independently to determine the actuation time, displacement, speed, pressure, etc. of each actuation system. The entire equipment realizes the linkage of each work station through the PLC control system. The rotation angle of the indexing plate 200 and the action sequence of each actuator are precisely controlled by a servo motor or a pneumatic component 800, and the repeat positioning accuracy can reach ±0.05 mm. Compared with traditional manual operation, this fully automated assembly solution greatly improves production efficiency and significantly reduces the defective rate of products, and is particularly suitable for the production requirements of small and medium batches and multiple varieties of household cleaning tool accessories. In practical applications, by replacing the positioning blocks 201 and related fixtures of different specifications, the equipment can be compatible with the assembly of various models of water squeezer racks or similar products, demonstrating good flexible production capabilities.
[0048] In some embodiments, such as Figure 1 , Figure 9 shown, the present application further optimizes the structural design of the positioning block 201. The indexing plate 200 adopts a circular disk body, and four positioning blocks 201 are evenly distributed on the circumference. Each positioning block 201 is provided with at least 1 bearing groove 2011 along the radial direction, which can be set according to the number of water squeezing parts 10 on each water squeezer rack. The notch of each bearing groove 2011 faces outwards, forming an open structure. When the push plate assembly 302 pushes the water squeezing part 10 along the radial direction, the water squeezing part 10 can smoothly enter the groove through the notch.
[0049] When multiple water squeezing parts 10 need to be assembled simultaneously, the bearing grooves 2011 can be set according to the number of water squeezing parts 10 to be assembled as required, that is, the positioning blocks 201 are set to different models or types according to the number of bearing grooves 2011, and they are detachably connected to the indexing plate 200, for example, by using a screw assembly method. At this time, since the indexing plate 200 is circular, when multiple bearing grooves 2011 are arranged in parallel, it is inevitable that not every bearing groove 2011 is strictly along the radial direction of the indexing plate 200. However, due to the size of the positioning block 201 relative to the indexing plate 200, it is very small, so each bearing groove 2011 on it is approximately parallel to the radial direction of the indexing plate 200, rather than strictly parallel. This multi-groove design enables a single positioning block 201 to carry multiple water squeezing parts 10 simultaneously according to requirements. When it is necessary to change the specifications and models of the water squeezing parts 10, only the corresponding positioning block 201 needs to be replaced, achieving the compatibility of the equipment.
[0050] Furthermore, such as Figure 9As shown, to ensure the stability of the dewatering component 10 during assembly as the indexing plate 200 rotates, at least three φ1.5mm negative pressure holes 2012 are evenly distributed at the bottom of each bearing groove 2011. These negative pressure holes 2012 are connected to the cylinder 801 of the pneumatic component 800 through an air passage or air pipe 802 (not shown in the figure) inside the indexing plate 200. To ensure that the bottom shape of the bearing groove 2011 is adapted to the shape of the dewatering component 10 when it enters the bearing groove 2011, that is, when the dewatering component 10 enters the bearing groove 2011, it is best to completely or nearly completely close the negative pressure holes 2012, so that when the cylinder 801 generates negative pressure and connects to the negative pressure holes 2012, the dewatering component 10 can be firmly adsorbed in the bearing groove 2011. For example, when the water-squeezing component 10 is square, regular polygonal, or has a planar or planar combination outer surface, the bottom of the bearing groove 2011 should also be planar; or when the water-squeezing component 10 is cylindrical, the bottom of the bearing groove 2011 should also be a cylindrical surface with the same shape as the water-squeezing component 10, and the diameter of its cylindrical surface should be greater than the diameter of the cylindrical surface of the water-squeezing component 10. This ensures that the water-squeezing component 10 can smoothly enter the bearing groove 2011 without generating too much friction with the groove wall of the bearing groove 2011 to avoid scratching the water-squeezing component 10. On the other hand, it ensures that the water-squeezing frame 10 can smoothly close the water-squeezing component 10, avoiding poor adsorption effect of the negative pressure hole 10 due to excessive gap between the bearing groove 2011 and the water-squeezing component 10. Therefore, the radial dimension of the negative pressure hole 10 should be at least smaller than the diameter of the water-squeezing component 10.
[0051] Furthermore, the number of negative pressure holes 2012 does not need to be strictly limited to three; it can be two or more. However, regardless of the number, they are all arranged along the length of the bearing groove 2011, with at least one at each end of the bearing groove 2011. This ensures both the stability of the water-squeezing component 10 being adsorbed within the bearing groove 2011 and the uniformity of the adsorption within the bearing groove 2011. Further, when there are multiple bearing grooves 2011, since multiple water-squeezing components 10 are simultaneously pushed into multiple bearing grooves 2011 by the pusher assembly 302, the adsorption demand for multiple water-squeezing components 10 is generated simultaneously. Therefore, the negative pressure holes on each bearing groove 2011 can be connected to the same cylinder 801 to ensure that the negative pressure in each negative pressure hole 2012 is generated simultaneously. The specific connection method is to connect the negative pressure port 2012 to the intake and exhaust ports of the same cylinder 801 through multiple vent pipes 802, or to connect one intake and exhaust port of a cylinder 801 to multiple negative pressure ports 2012 through a vent pipe 802 with multiple branch pipes.
[0052] When the wringer 10 enters the bearing groove 2011, the control system simultaneously activates negative pressure adsorption. The adsorption force and number of individual negative pressure holes 2012 should ensure that when multiple negative pressure holes 2012 are combined, the wringer 10 and the assembly of the wringer 10 and the wringer housing 20 remain stable as the indexing plate 200 rotates. This requires consideration of factors such as the mass of the wringer 10 and the wringer housing 20, the friction between the parts and the positioning block 201, the maximum rotational speed of the indexing plate 200, and the distance between the positioning block 201 and the rotation center of the indexing plate 200. For example, a single negative pressure hole can generate an adsorption force of 8 kPa to ensure the parts remain stable when the indexing plate 200 rotates to 60 rpm. This adsorption design effectively solves the problem of traditional mechanical clamping methods easily damaging the surface of parts, and is particularly suitable for household cleaning tools such as mops that have high aesthetic requirements and whose materials are easily scratched by metal materials.
[0053] In some embodiments, this application further optimizes the structural design of the feeding mechanism 300. For example... Figure 10 As shown, the feeding mechanism 300 also includes a loading platform 303. The loading platform 300 is located below the hopper 301. Since the hopper 301 adopts a gravity-feed structure, the dewatering component 10 in the hopper 301 can naturally fall from the opening below the hopper 301 into the loading groove 3031 above the loading platform 300 under its own gravity. The pusher assembly 302 can push the dewatering component 10 along the linear guide rail into the bearing groove 2011 of the positioning block 201 by the drive of a servo motor or pneumatic component. This structural design not only improves the positioning accuracy of the dewatering component 10, but also greatly improves the assembly efficiency of the dewatering component 10. Especially when multiple dewatering components 10 need to be assembled in a single dewatering frame, the simultaneous automated assembly of multiple dewatering components 10 can be realized.
[0054] Furthermore, such as Figure 8 , Figure 11 As shown, the feeding mechanism 300 also includes a distributing roller 304, which vertically divides the hopper 301 into a main body 3011 and a guiding part 3012. Four distributing grooves 3041 are evenly distributed on the surface of the distributing roller 304. The volume of each distributing groove 3041 is slightly larger than the volume of a single dewatering component 10, allowing the dewatering component 10 to enter the distributing groove 3041 and rotate with the distributing roller 304. When the distributing roller 304 rotates at a constant speed, the dewatering components 10 in the main body 3011 enter the distributing grooves 3041 sequentially by gravity. When they reach the bottom as the distributing roller 304 rotates, they fall into the guiding part 3012. This structure allows the dewatering components 10 to be continuously fed in a single queue, effectively solving the problem of easy jamming in traditional gravity-feeding systems.
[0055] Specifically, the lower part of the main body 3011 is designed in a funnel shape, which utilizes gravity to guide the dewatering components 10 to naturally gather towards the lower opening. The shape of the dewatering frame 10 is generally regular, such as polygonal or circular, and its surface is relatively smooth. The inclination angle of the funnel shape of the main body 3011 is generally set between 45° and 70°. This angle ensures that the dewatering components 10 slide smoothly under gravity, while preventing excessively fast sliding speed that could cause parts to collide, accumulate, or block. Moreover, the inner wall of the funnel shape is smoothed, effectively reducing the friction between the dewatering components 10 and the inner wall, further promoting the smooth descent of the dewatering components 10. The distributing roller 304 is located below the main body 3011, and its diameter is larger than the width of the lower opening of the main body 3011, effectively preventing a large number of dewatering components 10 from falling uncontrollably into the guide section 3012 under gravity. When the distributing roller 304 rotates at a certain speed, its outer distributing groove 3041 passes sequentially through the lower opening of the main body 3011. Due to the large diameter of the distributing roller 304, only one dewatering component 10 can fall precisely into the distributing groove 3041 at a time, thus achieving precise single feeding. To ensure the fitting accuracy between the distributing roller 304 and the lower opening of the main body 3011, the gap between them is controlled between 1-2 mm. This gap ensures that the distributing roller 304 can rotate freely while preventing the dewatering component 10 from accidentally falling out of the gap. In addition, this structural design also has good versatility and scalability. When it is necessary to change to a different specification of dewatering component 10 for production, only the corresponding size of the distributing roller 304 needs to be replaced and the size of the lower opening of the main body 3011 needs to be finely adjusted to quickly adapt to new production requirements, greatly improving the flexibility and adaptability of the production line.
[0056] Furthermore, when the dewatering frame 10 is cylindrical, to ensure smoother falling within the guide section 3012 onto the loading platform 300, the guide section 3012 employs an inclined design, for example, with an inclination angle of 15°-30°. This angle range ensures that the dewatering component 10 rolls smoothly under gravity, while preventing excessive rolling speed due to excessive inclination, which could cause collisions or deviation from the track. The surface of the guide section 3012 is smoothed, resulting in a low coefficient of friction, allowing the cylindrical dewatering component 10 to roll easily on it. To further guide the dewatering component 10 to roll accurately onto the loading platform 303, guide baffles are also provided on both sides of the guide section 3012. The inner sides of the guide baffles are also smoothed to prevent the dewatering component 10 from shifting.
[0057] Furthermore, such as Figure 10As shown, a material loading groove 3031 matching the shape of the dewatering component 10 is formed on the upper surface of the loading platform 303. The width of the groove and the diameter of the component form a small clearance fit, allowing the dewatering component 10 to have a fairly accurate position in the loading groove 3031 without the need for an additional positioning device. When the dewatering component 10 falls into the loading groove 3031 through the guide section 3012, the arrival signal of the dewatering component 10 can be detected in real time by setting a pressure sensor at the bottom of the groove and a photoelectric sensor on the side, to ensure that the pusher assembly 302 operates at the appropriate time; or the time taken for the dewatering component 10 to pass through the guide section 3012 can be statistically analyzed to set the time interval between the operation of the pusher assembly 302 and the distribution roller 304, thereby reducing equipment costs. In addition, as Figure 11 As shown, the pusher assembly 302 adopts a composite structure of push rod 3021 and plate 3022. The push rod 3021 is made of aluminum alloy and its front end is designed as a smooth plane to avoid damaging the surface of the parts during the pushing process. In addition, the ends of multiple push rods facing the positioning block 301 are flush to ensure that when there are multiple water-squeezing parts 10, they can be pushed to a relatively flush position by multiple push rods 3021, thereby ensuring the assembly accuracy requirements. The plate 3022 is connected to the pneumatic assembly 800 or servo motor through a linear guide rail and reciprocates along the length of the material loading groove 3031. When the plate 3022 drives the push rod 3021 to move, the push rod 3021 extends into the material loading groove 3031 and pushes the water-squeezing parts 10 along the groove into the bearing groove 2011 of the positioning block 201, thereby ensuring the stability and continuity of the feeding.
[0058] In some embodiments, this application further optimizes the transplanting mechanism 400 to enable it to efficiently and accurately complete the transplanting of the wringer housing 20. For example... Figure 4 As shown, the transplanting mechanism 400 consists of a first transverse track device 401, a first longitudinal track device 402, and a first clamping device 403. The longitudinal track and the transverse track together form the moving track device of the first clamping device 403. The two are perpendicular to each other, and through mechanical calibration and adjustment, the perpendicularity of movement in both directions is ensured. This guarantees that the first clamping device 403 can coordinate with the transverse movement during longitudinal movement to achieve complex predetermined trajectory movements. The stroke of the longitudinal track can be customized according to actual production needs, for example, between 200-500mm, to meet the transplanting requirements of different sized dewatering rack housings 20.
[0059] When the positioning block 201 rotates to the transplanting station, the control system precisely controls the movement of the first transverse track device 401 and the first longitudinal track device 402 according to a preset program. First, the first transverse track device 401 moves the first clamping device 403 above the dewatering rack housing 20. Then, the first longitudinal track device 402 drives the first clamping device 403 to descend, causing the grippers to clamp the dewatering rack housing 20. Next, the first longitudinal track device 402 drives the first clamping device 403 to rise. Subsequently, the first transverse track device 401 moves it along a predetermined trajectory above the positioning block 201. Finally, the first longitudinal track device 402 descends again, precisely placing the dewatering rack housing 20 above the dewatering component 10 on the positioning block 201.
[0060] Furthermore, due to inevitable machining errors during the production process, the clamping force of the first clamping device 403 cannot be strictly controlled. This can lead to the dewatering rack housing 20 not being clamped or falling back to its bearing position immediately after being clamped, thus occupying the machining area and affecting the assembly of the next dewatering rack housing 20. Alternatively, various external environmental factors can cause foreign objects to enter the bearing position of the dewatering rack housing 20. To avoid this situation, such as... Figure 4 As shown, the dewatering rack assembly equipment of this application is also equipped with a cleaning device to clean the bearing position of the dewatering rack housing 20, thereby ensuring that after the first clamping device 403 is activated, the bearing position of the previous dewatering rack housing 20 is empty, so that subsequent dewatering rack housings 20 can continue to be fed. The cleaning device can be driven by setting a separate cleaning track and then controlling the servo motor or pneumatic component 800 by the control system. This setting ensures the independence of the cleaning device, thereby facilitating maintenance or interchangeability with other equipment; or, in accordance with the principles of cost saving and structural simplification, the moving track of the cleaning device can be combined with the moving track of the first clamping device 403, that is, the cleaning device is set on the combination of the first transverse track device 401 and the first longitudinal track device 402, and is located behind the first clamping device 403, so that the movement of the first clamping device 403 is used to drive the movement of the cleaning device.
[0061] Specifically, since the cleaning device only needs to move laterally to sweep across the bearing position of the wringer housing 20, its lower end should be lower than the bearing surface of the wringer housing 20, and it is made of flexible material, such as the first cleaning brush 404 or soft rubber strips, soft cloth and similar materials.
[0062] Furthermore, the first transverse track device 401 includes a transversely extending first transverse slide rail 4011 and a first transverse slider 4012 that can slide on it. The first transverse slide rail 4011 is made of high-strength alloy steel, precision forged and machined, and its surface is ground and hardened. This not only ensures the wear resistance of the slide rail but also provides a good foundation for the smooth sliding of the slider. The first end of the first transverse slide rail 4011 extends above the indexing plate 200, allowing the first clamping device 403 to smoothly move the dewatering rack housing 20 to the positioning block 201 on the indexing plate 200. The first transverse slider 4012 is connected to the pneumatic component 800, so that under the control of the control system, the pneumatic component 800 can drive the first transverse slider 4012 to slide back and forth on the first transverse slide rail 4011. Similarly, the first longitudinal track device 402 consists of a longitudinally extending first longitudinal slide rail 4021 and a first longitudinal slider 4022 sliding along it. The first longitudinal slide rail 4021 is also made of high-quality material and is mounted on the first transverse slider 4012, cooperating with the first transverse track device 401 to realize two-dimensional motion in space. The surface treatment requirements of the first longitudinal slide rail 4021 are similar to those of the first transverse slide rail 4011, ensuring the smooth sliding of the first longitudinal slider 4022. The first longitudinal slider 4022 is also connected to the pneumatic assembly 800, so that under the control of the control system, the pneumatic assembly 800 can drive the first longitudinal slider 4022 to slide on the first longitudinal slide rail 4011. During longitudinal movement, because it is mounted on the first transverse slider 4012, it can move laterally synchronously with the movement of the first transverse slider 4012, thereby realizing complex motion trajectories. The first clamping device 403 is fixed on the first longitudinal slider 4022 and adopts a pneumatic gripper design. The opening and closing action of the gripper is driven by the pneumatic component 800 controlled by the control system, which can quickly and firmly clamp the wringer housing 20. The gripper design fully considers the shape characteristics of the wringer housing 20 and adopts an adjustable gripper structure to adapt to wringer housings 20 of different sizes and shapes. By adjusting the spacing and clamping force of the gripper, it can be ensured that the wringer housing 20 will not be damaged during the clamping process, while ensuring sufficient clamping force to prevent the housing from falling during transplantation. At this time, since the wringer housing 20 is obviously placed in its bearing position, the cleaning device only needs to sweep laterally across the bearing position of the wringer housing 20 to perform cleaning. Therefore, the cleaning device and the first longitudinal track 402 remain relatively stationary only in the lateral position. Therefore, in this embodiment, the cleaning device is fixedly mounted on the first transverse slider 4012, and can sweep across the bearing position of the squeezing rack housing 20 as the first clamping device 403 and the first longitudinal track device 402 move laterally, thereby realizing the reuse of the structure and saving equipment costs.
[0063] In the dewatering rack assembly equipment of this application, in order to improve the feeding efficiency and accuracy of the dewatering rack housing 20, such as Figure 1 As shown, a shell conveyor belt 700 is also provided, and the second end of the first transverse slide rail 4011 of the first transverse track device 401 extends above the shell conveyor belt 700. The shell conveyor belt 700 adopts a synchronous belt drive system, which is stable in operation and low in noise. The surface of the conveyor belt is specially treated to have a certain friction, which can ensure that the dewatering rack shell 20 will not easily slip during the conveying process. At the same time, the conveyor belt is equipped with a speed adjustment device, which can flexibly adjust the conveying speed according to actual production needs. In order to ensure the accurate positioning of the dewatering rack shell 20 on the shell conveyor belt 700, the shell conveyor belt 700 can also be provided with equally spaced positioning grooves, the size of which is adapted to the size of the dewatering rack shell 20. Through the coordinated work with the shell conveyor belt 700, the efficient and precise transfer of the dewatering rack shell 20 is achieved.
[0064] In some embodiments, this application further optimizes the discharge mechanism 600, such as... Figure 8 As shown, similar to the transplanting mechanism 400, the discharge mechanism 600 consists of a second transverse track device 601, a second longitudinal track device 602, and a second clamping device 603. This mechanism achieves rapid unloading of the assembled dewatering rack housing 20 through accurate positioning, effectively improving production efficiency. The second transverse track device 601 has the function of precisely controlling the transverse movement of the second clamping device 603, while the second longitudinal track device 602 is mainly responsible for controlling the longitudinal movement of the second clamping device 603. Both are driven by servo motors or pneumatic components 800. The second clamping device 603 is mounted on the second longitudinal track device 602 and is used to reliably clamp the dewatering rack housing 20. It also uses pneumatic components 800 to drive the opening and closing of its grippers. The shape and size of the grippers are optimized according to the external characteristics of the dewatering rack housing 20, enabling omnidirectional and stable clamping of the housing. The grippers are also equipped with pressure sensors, which can monitor the magnitude of the clamping force in real time, ensuring that the housing will not fall due to insufficient clamping force or be damaged due to excessive clamping force during the clamping process.
[0065] When the positioning block 201 rotates with the indexing plate 200 to the unloading station, the discharge mechanism 600 begins to operate. The control system first controls the second transverse track device 601 to move the second clamping device 603 above the unloading station according to a preset program. Next, the second longitudinal track device 602 drives the second clamping device 603 to descend to a suitable height, allowing the grippers to accurately clamp the dewatering rack housing 20. Then, the second longitudinal track device 602 drives the second clamping device 603 to rise, and then the second transverse track device 601 moves the second clamping device 603, along with the clamped dewatering rack housing 20, out of the indexing plate 200 according to a predetermined trajectory and places it at the designated discharge position, completing the entire unloading process.
[0066] Specifically, the second transverse track device 601 consists of a transversely extending second transverse slide rail 6011 and a cooperating second transverse slider 6012. The second longitudinal track device 602 consists of a longitudinally extending second longitudinal slide rail 6021 and a cooperating second longitudinal slider 6022. Both the second transverse slide rail 6011 and the second longitudinal slide rail 6021 are made of high-strength aluminum alloy steel, and their surfaces are ground and hardened to ensure their wear resistance and the stability of their sliding fit. The second longitudinal slide rail 6021 is fixed on the second transverse slider 6012, and the second clamping device 603 is fixed on the second longitudinal slider 6022. This allows the second clamping device 603 to slide laterally along with the second longitudinal track device 602 as the second transverse slider 6012 slides, thereby moving the second clamping device 603 to a specified transverse position.
[0067] The design of this 600-type discharge mechanism enables efficient and precise operation of the dewatering rack assembly equipment during the material feeding stage, improving production efficiency and product quality. In actual production, it effectively reduces production failures and defect rates caused by inaccurate or untimely material feeding, bringing significant efficiency improvements to the enterprise. Simultaneously, this discharge mechanism boasts excellent versatility and adjustability; through simple parameter adjustments and gripper replacements, it can adapt to the material feeding needs of dewatering rack shells of different specifications and shapes, meeting the diverse production requirements of enterprises.
[0068] Accordingly, to prevent the water-squeezing component 10 on the positioning block 201 from having residue due to assembly errors or other debris accidentally entering it, such as... Figure 8 As shown, the discharge mechanism 600 is also equipped with a second cleaning brush 604 to clean the positioning block 201 during the process of the second clamping device 603 moving laterally to remove the assembled dewatering rack housing 20 from the indexing plate 200. Therefore, the second cleaning brush 604 is fixedly connected to the second lateral slider 6012 so that it only moves laterally, and is reused with the second lateral track device 601 that restricts the lateral movement of the second clamping device 603 to save costs.
[0069] To further reduce equipment costs, in this application, the first transverse track device 401 and the second transverse track device 601 can also be integrated. That is, when the indexing plate 200 is provided with four symmetrical positioning blocks 201, the transplanting mechanism 400 and the discharging mechanism 600 can respectively perform transverse and longitudinal movements on the squeezing rack housing 20 on the two opposite positioning blocks 201. Therefore, the first transverse slide rail 4011 and the second transverse slide rail on the first transverse track device 401 are arranged parallel to each other or integrated, and the first transverse slider 4012 and the second transverse slider 6012 are fixedly connected as one unit, thereby being driven by the same pneumatic component 800 or servo motor, thus saving the number of driving components. Correspondingly, the first longitudinal track 402 and the second longitudinal track 602 can also be merged, that is, the first longitudinal slide rail 4021 and the second longitudinal slider 6021 are arranged parallel to each other, and the first longitudinal slider 4022 and the second longitudinal slider 6022 are fixedly connected as one unit, so as to be driven by the same pneumatic component 800 or servo motor.
[0070] This application also provides an assembly method for the control system applied to the above-mentioned dewatering rack assembly equipment, which can efficiently and accurately complete the assembly of the dewatering rack. The method covers four key steps: feeding, transplanting, pressing and unloading, and each step is further refined to ensure the smoothness and stability of the entire assembly process.
[0071] S1, Material Loading Stage
[0072] After the positioning block 201 rotates to the loading station, the distribution roller 304 starts to rotate. The rotation of the distribution roller 304 drives the water squeezing parts 10 in the main body 3011 to roll down to the loading platform 303 in sequence through the guide part 3012. During this process, the rotation speed and rotation interval of the distribution roller 304 are strictly set to ensure that the water squeezing parts 10 can roll down in an orderly manner and one by one, avoiding blockage or overlap.
[0073] Subsequently, the pusher assembly 302 moves towards the indexing plate 200, pushing the dewatering component 10 on the loading platform 303 to the positioning block 201. The moving speed and pushing force of the pusher assembly 302 have also been strictly adjusted to ensure that the dewatering component 10 reaches the positioning block 201 smoothly without damaging it. After completing the pushing action, the pusher assembly 302 moves away from the indexing plate 200 to reset, preparing for the next pushing action.
[0074] S2, Transplanting Stage
[0075] When the positioning block 201 rotates to the transplanting station, the first clamping device 403 begins to move longitudinally to the position of the housing conveyor belt 700.
[0076] Next, the first clamping device 403 moves laterally above the positioning block 201. Simultaneously, the first cleaning brush 404 moves laterally to clean the placement position of the dewatering rack housing 20 on the housing conveyor belt 700. This cleaning action effectively removes dust and any unclamped dewatering rack housings 20 from the housing conveyor belt 700, ensuring the accuracy and stability of subsequent placement of the dewatering rack housing 20.
[0077] Subsequently, the first clamping device 403 moves longitudinally, smoothly placing the dewatering rack housing 20 onto the positioning block 201. During placement, since the dewatering rack housing 20 has a mounting groove 21 for mounting the dewatering component 10, and the groove opening of the mounting groove 21 is flared, even if the dewatering rack housing 20 has a slight offset, the flared opening can guide the dewatering component 10 to align with the mounting groove 21, thereby ensuring that the slight positional offset of the dewatering component housing 20 caused by processing and movement will not affect the assembly.
[0078] Finally, the first clamping device 403 moves above the housing conveyor belt 700, and the first cleaning brush 404 moves to the side of the housing conveyor belt 700 to reset, preparing for the next transplanting operation.
[0079] S3, Pressing Stage
[0080] After the positioning block 201 rotates to the pressing station, the pressure plate 501 begins to move downwards. The moving speed and pressure of the pressure plate 501 are set according to factors such as the material and size of the water-squeezing component 10 and the water-squeezing frame housing 20. The pressure plate 501 presses down on the water-squeezing frame housing 20, allowing the water-squeezing component 10 to smoothly enter the mounting groove 21 on the water-squeezing frame housing 20, completing the assembly.
[0081] After assembly, the pressure plate 501 moves upward to disengage from the dewatering rack housing 20 and resets, awaiting the next pressing operation.
[0082] S4, Material feeding stage
[0083] When the positioning block 201 rotates to the unloading station, the second clamping device 603 moves longitudinally to the position of the positioning block 201 and clamps the dewatering frame housing 20 with the dewatering component 10 assembled. The clamping method of the second clamping device 603 is similar to that of the first clamping device 403, ensuring that the assembled dewatering frame can be firmly clamped.
[0084] This dewatering rack assembly method offers significant advantages. In actual production, it greatly improves the assembly efficiency of the dewatering rack. Through close coordination and precise control of each step, it reduces manual intervention and minimizes errors caused by human factors. Simultaneously, because each step is rigorously designed and optimized, assembly quality is effectively guaranteed, increasing the product yield. Furthermore, this method is highly versatile and adaptable, allowing for flexible adjustments based on different production needs and product specifications, providing strong support for enterprise production.
