Description

Technical Field

[0001] This utility model relates to the field of press-fitting technology, and in particular to a multi-station filter press-fitting servo press. Background Technology

[0002] Traditional filter assembly processes commonly suffer from low production efficiency and poor quality stability. Early production relied primarily on manual pressing, which was not only labor-intensive and inefficient, but also resulted in inconsistent product quality and a high scrap rate due to varying operator skill levels. With the development of automation technology, mechanical pressing equipment has been gradually adopted.

[0003] However, in the actual filter pressing process, traditional single-station presses typically use a one-time pressing method, which can easily lead to filter deformation or poor assembly. This is mainly because filter pressing requires two key stages: the pre-pressing stage requires gradually tightening the edges of the filter to prevent the metal mesh from wrinkling or shifting due to sudden force; the final pressing stage requires precise control of the final pressing force and displacement to ensure that the filter and the substrate achieve an interference fit without damaging the mesh structure. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a multi-station filter screen pressing servo press that effectively improves filter screen installation efficiency and ensures high yield. It addresses the problems of low filter screen pressing efficiency, inaccurate positioning, and insufficient automation in existing technologies.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A multi-station filter pressing servo press includes a frame and a pressing device. The pressing device is installed on the upper end of the frame. A filter pressing assembly is provided on the frame and connected to the pressing device. The filter pressing assembly includes a pressing head assembly and a moving platform. Multiple filter receiving parts are evenly spaced on the frame. The moving platform is located above the filter receiving parts and is fixedly connected to the pressing device. The pressing head assembly is fixedly installed on the moving platform. The pressing head assembly includes a pre-pressing head and a final pressing head. The pre-pressing head includes multiple pre-pressing heads evenly spaced, and the final pressing head includes multiple final pressing heads evenly spaced. The pre-pressing heads and final pressing heads are arranged parallel to each other. Each pre-pressing head and final pressing head corresponds one-to-one with a filter receiving part. The end face of the pre-pressing head facing the filter receiving part has an inwardly concave conical surface. The pressing device consists of a servo motor and a pressure rod. The servo motor can drive the pressure rod to move up and down. The structure of the pressure rod and its connection with the servo motor are common in the market and will not be described in detail in this application.

[0007] The working principle of this application is as follows: First, the filter screen and frame are placed sequentially in the filter screen receiving section on the frame. Then, the moving platform drives the pressing head assembly to move horizontally, ensuring the pre-pressing head is accurately positioned directly above the filter screen receiving section. Next, the pressing device starts and drives the moving platform downwards, simultaneously pressing down the pre-pressing head. Because the end of the pre-pressing head facing the filter screen has an inwardly concave conical surface, during the pressing process, the edge of the frame gradually narrows along the conical surface, achieving progressive pre-pressing of the filter screen edge. After pre-pressing is completed, the pressing device moves upwards to reset, and the moving platform again drives the final pressing head to move above the filter screen receiving section. Subsequently, the pressing device moves downwards again, driving the final pressing head to perform final pressing of the filter screen frame, ensuring the frame is completely compressed. After final pressing is completed, the equipment resets, and the operator can remove the assembled filter screen from the filter screen receiving section.

[0008] This application's solution achieves multi-station continuous operation in the filter pressing process by setting multiple evenly spaced filter housings and corresponding pre-pressing and final pressing heads, significantly improving production efficiency. Simultaneously, it employs a staged pressing method. The pre-pressing head, equipped with a conical structure, progressively narrows the filter edge, effectively preventing wrinkles or displacement of the metal mesh due to sudden force. The final pressing head achieves precise control of the final pressing force and displacement, ensuring a stable interference fit between the filter and the substrate without damaging the mesh structure, thereby greatly improving product consistency and assembly quality. This design not only reduces the scrap rate but also significantly reduces the labor intensity of operators.

[0009] Preferably, a flat pressure block is fixedly disposed on the end face of the final pressure head facing the filter screen receiving portion. This ensures that the pressing force during the final pressing stage is evenly distributed across the frame surface via the flat pressure block, resulting in a more stable and precise final pressing effect. This structural design helps improve the flatness and stress uniformity of the pressing contact surface, preventing filter screen deformation or damage due to localized stress concentration.

[0010] Preferably, the pre-pressing head includes a first housing, a first push rod, and a first elastic element. The first elastic element is installed inside the first housing, and the first push rod is slidably engaged with the first housing. One end of the first push rod is fixedly connected to the first elastic element, and the other end extends outside the first housing. The conical surface is provided on the end face of the first housing facing the filter screen receiving portion. Specifically, the first housing is fixedly installed on the moving platform, and the first elastic element is confined within the first housing. During operation, when the pre-pressing head descends with the moving platform and contacts the filter screen assembly, the first housing first contacts the filter screen frame. Its end face has a concave conical surface, which guides the frame to gradually close, achieving progressive pressing. Simultaneously, the first push rod continues to extend downward and contacts the filter screen. After contact, the first push rod retracts upward into the first housing under the action of the filter screen, compressing the first elastic element. This structural design allows the push rod to automatically adjust its extension length according to the actual stress state of the filter screen, thereby avoiding local stress concentration or filter screen damage caused by rigid contact. The first push rod serves to limit and assist in pressing the filter screen, preventing it from shifting or being damaged during the pre-pressing process; while the first elastic element provides the first push rod with a restoring force and a buffering effect.

[0011] Preferably, the final pressure head includes a second housing, a second push rod, and a second elastic element. The second elastic element is installed inside the second housing, and the second push rod is slidably engaged with the second housing. One end of the second push rod is fixedly connected to the second elastic element, and the other end extends outside the second housing. The flat pressure block is fixedly disposed on the end face of the second housing facing the filter screen receiving portion. Specifically, the structural design of the final pressure head is similar to that of the pre-pressure head, also including a floating pressure structure composed of a housing, a push rod, and an elastic element. Its working mechanism is also similar, so it will not be described in detail. The difference is that a flat pressure block is fixedly disposed on the end face of the second housing of the final pressure head. Its main function is to flatten and press the filter screen frame during the final pressure stage, ensuring that the frame is completely attached to the substrate, thereby enabling the filter screen to be finally formed in place, improving assembly accuracy and finished product quality.

[0012] Preferably, the flat pressing block includes a filter screen pressing block and a frame pressing block. The size of the filter screen pressing block is smaller than that of the frame pressing block. The frame pressing block is fixedly installed on the end face of the second housing facing the filter screen receiving portion, and the filter screen pressing block is fixedly installed on the end face of the frame pressing block facing the filter screen receiving portion. The frame pressing block is larger in size and is used to cover and press the filter screen frame area to ensure that it is fully closed and forms a stable interference fit with the substrate. The filter screen pressing block is smaller in size and is located in the central area of ​​the frame pressing block. It is specifically used to apply local pressure to the middle of the filter screen to prevent wrinkles or bulges due to uneven force during the final pressing process, which significantly improves the overall forming accuracy and assembly quality of the filter screen.

[0013] Preferably, the frame further includes a support platform, on which the filter screen receiving portion is disposed, and the support platform is located below the pressing head assembly. This facilitates the installation and adjustment of the filter screen receiving portion, as well as the positioning or processing operation of the pressing head assembly.

[0014] Preferably, the filter housing includes a hollow limiting slider, a third elastic element, and a positioning rod. Both the third elastic element and the hollow limiting slider are installed within the receiving platform. One end of the third elastic element is fixedly connected to the receiving platform, and the other end is fixedly connected to the hollow limiting slider. The outer wall of the hollow limiting slider slides in contact with the receiving platform. The positioning rod is slidably installed inside the receiving platform, and its lower end can abut against the machine frame. The positioning rod slides in contact with the inner wall of the hollow limiting slider, and a filter housing cavity is formed between the upper end of the positioning rod and the inner wall of the hollow limiting slider. Specifically, the filter housing cavity formed by the positioning rod and the inner wall of the hollow limiting slider can be used to stably place the filter sheet and its frame. Furthermore, the lower end of the positioning rod abuts against the machine frame, effectively preventing the filter assembly from shifting downwards during the pressing process, further improving pressing accuracy and finished product quality.

[0015] This design incorporates a filter housing consisting of a hollow limiting slider, a third elastic element, and a positioning rod. During the pressing process of the pre-pressing head or final pressing head, the hollow limiting slider contacts the first or second housing and moves downwards accordingly, gradually exposing the filter frame. This allows the conical or flat pressing block to more fully press the filter frame against it, ensuring no positional shift occurs and effectively improving the tightness and consistency of the pressing process. The third elastic element provides a restoring force to the hollow limiting slider, ensuring it automatically returns to its initial position after pressing.

[0016] Preferably, the system further includes an ejection mechanism located below the filter screen receiving portion. The ejection mechanism comprises an ejection part and a driving device. The ejection part is fixedly mounted on the driving device and slides against the receiving platform. The upper end of the ejection part contacts the lower end of the positioning rod. The driving device is installed within the frame and can be a commercially available cylinder or motor. This allows the driving device to move the ejector rod upwards after pressing, thereby pushing the positioning rod and the filter screen assembly upwards as a whole, achieving automatic ejection of the filter screen product. This effectively improves the automation level and production efficiency of the equipment, avoiding the safety hazards and operational inconvenience caused by manual handling.

[0017] Preferably, a fourth elastic element is provided between the lower end of the positioning rod and the receiving platform. When the positioning rod moves upward, the fourth elastic element is in a compressed state. In this way, the fourth elastic element provides a restoring force for the positioning rod to reset. Moreover, the presence of the fourth elastic element can also buffer the impact force during the ejection process, ensuring the stability of the filter screen finished product ejection process.

[0018] The first, second, third, and fourth elastic elements in this application can all be springs.

[0019] Preferably, the mobile platform includes a support part and a moving part. The support part is fixedly connected to the pressing device, and the moving part is slidably connected to the support part. The pressing head assembly is fixedly mounted on the moving part. A guide column is fixedly provided on the support part, and a guide hole is provided on the material receiving platform. The guide column and the guide hole cooperate with each other. This allows for flexible switching of the pressing head in the horizontal direction, adapting to continuous operation at multiple workstations. Simultaneously, the guide column and guide hole ensure good guidance and positioning accuracy during the pressing process, avoiding pressing errors caused by offset. The moving part can adopt a combination of a cylinder and a slider, or a combination of a motor and a slider guide rail, which are commonly available on the market. Therefore, the structure of the moving part will not be described in detail in this application.

[0020] In summary, this multi-station filter pressing servo press effectively improves filter installation efficiency and ensures high yield. It solves the problems of low filter pressing efficiency, inaccurate positioning, and insufficient automation in existing technologies. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] In the description of this utility model, it should be understood that the orientation and positional relationship indicated by terms such as "up", "down", "left", "right", "front", "back", "vertical", "bottom", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0042] Reference Figures 1-6As shown, a multi-station filter screen pressing servo press includes a frame 1 and a pressing device 2. The pressing device 2 is installed on the upper end of the frame 1. A filter screen pressing assembly 3 is provided on the frame 1 and connected to the pressing device 2. The filter screen pressing assembly 3 includes a pressing head assembly 4 and a moving platform 5. A plurality of filter screen receiving parts 6 are evenly spaced on the frame 1. The moving platform 5 is located above the filter screen receiving parts 6 and is fixedly connected to the pressing device 2. The pressing head assembly 4 is fixed. Mounted on the mobile platform 5, the pressing head assembly 4 includes a pre-pressing head 41 and a final pressing head 42. The pre-pressing head 41 includes multiple pre-pressing heads 41 evenly spaced, and the final pressing head 42 includes multiple final pressing heads 42 evenly spaced. The pre-pressing head 41 and the final pressing head 42 are arranged parallel to each other. Both the pre-pressing head 41 and the final pressing head 42 correspond one-to-one with the filter screen receiving part 6. The end face of the pre-pressing head 41 facing the filter screen receiving part 6 has an inwardly concave conical surface 43. The pressing device 2 consists of a servo motor and a pressing rod. The servo motor can drive the pressing rod to move up and down. The structure of the pressing rod and its connection method with the servo motor are common in the market and will not be described in detail in this application.

[0043] The working principle of this application is as follows: First, the filter screen and frame are placed sequentially in the filter screen receiving part 6 on the frame 1. Then, the moving platform 5 drives the pressing head assembly 4 to move horizontally, so that the pre-pressing head 41 is accurately positioned directly above the filter screen receiving part 6. Next, the pressing device 2 starts and drives the moving platform 5 downward, causing the pre-pressing head 41 to press down synchronously. Since the end of the pre-pressing head 41 facing the filter screen has an inwardly concave conical surface 43, during the pressing process, the edge of the frame gradually narrows along the conical surface 43, achieving progressive pre-pressing and forming of the filter screen edge. After pre-pressing is completed, the pressing device 2 moves upward to reset, and the moving platform 5 again drives the final pressing head 42 to move above the filter screen receiving part 6. Then, the pressing device 2 moves downward again, driving the final pressing head 42 to perform final pressing on the filter screen frame, ensuring the frame is completely pressed. After final pressing is completed, the equipment resets, and the operator can remove the assembled filter screen from the filter screen receiving part 6.

[0044] This application's solution, by setting multiple evenly spaced filter screen receiving sections 6 and corresponding pre-pressing heads 41 and final pressing heads 42, achieves multi-station continuous operation in the filter screen pressing process, significantly improving production efficiency. Simultaneously, it employs a staged pressing method. The pre-pressing head 41, equipped with a conical surface 43 structure, progressively narrows the filter screen edges, effectively preventing wrinkles or displacement of the metal mesh surface due to sudden force. The final pressing head 42 achieves precise control of the final pressing force and displacement, ensuring a stable interference fit between the filter screen and the substrate without damaging the mesh structure, thereby greatly improving product consistency and assembly quality. The design in this application not only reduces the scrap rate but also significantly reduces the labor intensity of operators.

[0045] Additionally, refer to Figure 7 As shown, a flat pressure block 44 is fixedly mounted on the end face of the final pressure head 42 facing the filter screen receiving portion 6. This allows the pressing force during the final pressing stage to be evenly applied to the frame surface via the flat pressure block 44, resulting in a more stable and precise final pressing effect. This structural design helps improve the flatness and stress uniformity of the pressing contact surface, preventing filter screen deformation or damage due to localized stress concentration.

[0046] Additionally, refer to Figure 5 and Figure 6 As shown, the pre-pressing head 41 includes a first housing 411, a first push rod 412, and a first elastic element 413. The first elastic element 413 is installed inside the first housing 411, and the first push rod 412 is slidably engaged with the first housing 411. One end of the first push rod 412 is fixedly connected to the first elastic element 413, and the other end extends out of the first housing 411. A conical surface 43 is provided on the end face of the first housing 411 facing the filter screen receiving portion 6. Specifically, the first housing 411 is fixedly installed on the moving platform 5, and the first elastic element 413 is confined within the first housing 411. During operation, when the pre-pressing head 41 descends with the moving platform 5 and contacts the filter screen assembly, the first housing 411 first contacts the filter screen frame. Its end face is provided with an inwardly concave conical surface 43, which can guide the frame to gradually close, realizing progressive pressing. At the same time, the first push rod 412 continues to extend downward and contacts the filter screen. Upon contact, the first push rod 412 retracts upward into the first housing 411 under the action of the filter screen, compressing the first elastic element 413. This structural design allows the push rod to automatically adjust its extension length according to the actual stress state of the filter screen, thereby avoiding local stress concentration or filter screen damage caused by rigid contact. The first push rod 412 serves to limit and assist in pressing the filter screen, preventing displacement or damage during pre-compression; while the first elastic element 413 provides a restoring force and buffer for the first push rod 412.

[0047] Additionally, refer to Figure 7 and Figure 8As shown, the final pressure head 42 includes a second housing 421, a second push rod 422, and a second elastic element 423. The second elastic element 423 is installed inside the second housing 421. The second push rod 422 is slidably engaged with the second housing 421. One end of the second push rod 422 is fixedly connected to the second elastic element 423, and the other end extends out of the second housing 421. A flat pressure block 44 is fixedly disposed on the end face of the second housing 421 facing the filter screen receiving portion 6. Specifically, the structural design of the final pressure head 42 is similar to that of the pre-pressure head 41, also including a floating pressure structure composed of a housing, a push rod, and an elastic element. Its working mechanism is also similar, so it will not be described in detail. The difference is that a flat pressure block 44 is fixedly disposed on the end face of the second housing 421 of the final pressure head 42. Its main function is to flatten and press the filter screen frame during the final pressure stage, ensuring that the frame is completely attached to the substrate, thereby making the filter screen finally formed in place, improving assembly accuracy and finished product quality.

[0048] Additionally, refer to Figure 8 As shown, the flat pressing block 44 includes a filter screen pressing block 441 and a frame pressing block 442. The size of the filter screen pressing block 441 is smaller than that of the frame pressing block 442. The frame pressing block 442 is fixedly installed on the end face of the second housing 421 facing the filter screen receiving portion 6, and the filter screen pressing block 441 is fixedly installed on the end face of the frame pressing block 442 facing the filter screen receiving portion 6. The frame pressing block 442 is larger in size and is used to cover and press the filter screen frame area to ensure that it is fully closed and forms a stable interference fit with the substrate. The filter screen pressing block 441 is smaller in size and is located in the central area of ​​the frame pressing block 442. It is specifically used to apply local pressure to the middle of the filter screen to prevent wrinkles or bulges due to uneven force during the final pressing process, which significantly improves the overall forming accuracy and assembly quality of the filter screen.

[0049] Additionally, refer to Figure 1 As shown, the frame 1 also includes a material receiving platform 7, on which the filter screen receiving part 6 is disposed. The material receiving platform 7 is located below the pressing head assembly 4. This facilitates the installation and adjustment of the filter screen receiving part 6, as well as the positioning or processing operation of the pressing head assembly 4.

[0050] Additionally, refer to Figure 4As shown, the filter housing 6 includes a hollow limiting slider 61, a third elastic element 62, and a positioning rod 63. Both the third elastic element 62 and the hollow limiting slider 61 are installed within the receiving platform 7. One end of the third elastic element 62 is fixedly connected to the receiving platform 7, and the other end is fixedly connected to the hollow limiting slider 61. The outer wall of the hollow limiting slider 61 slides against the receiving platform 7. The positioning rod 63 is slidably installed inside the receiving platform 7, and its lower end can abut against the frame 1. The positioning rod 63 slides against the inner wall of the hollow limiting slider 61, and a filter housing cavity 9 is formed between the upper end of the positioning rod 63 and the inner wall of the hollow limiting slider 61. Specifically, the filter housing cavity 9 formed by the positioning rod 63 and the inner wall of the hollow limiting slider 61 can be used to stably place the filter screen and its frame. Furthermore, the lower end of the positioning rod 63 abuts against the frame 1, effectively preventing the filter assembly from shifting downwards during the pressing process, further improving the pressing accuracy and finished product quality.

[0051] In this design, a filter housing 6 consisting of a hollow limiting slider 61, a third elastic element 62, and a positioning rod 63 is provided. This allows the hollow limiting slider 61 to contact the first housing 411 or the second housing 421 and move downwards during the pressing process of the pre-pressing head 41 or the final pressing head 42, gradually exposing the filter frame. This enables the conical surface 43 or the flat pressing block 44 to more fully press the filter frame and ensures that the frame does not shift position, effectively improving the tightness and consistency of the pressing process. The third elastic element 62 provides a restoring force to the hollow limiting slider 61, ensuring that it automatically returns to its initial position after pressing.

[0052] Additionally, refer to Figure 2 , Figure 3 and Figure 4 As shown, it also includes an ejection mechanism 8, which is located below the filter screen receiving part 6. The ejection mechanism 8 includes an ejection part 81 and a drive device 82. The ejection part 81 is fixedly installed on the drive device 82 and slides with the receiving platform 7. The upper end of the ejection part 81 contacts the lower end of the positioning rod 63. The drive device 82 is installed inside the frame 1 and can be a commonly available cylinder or motor. In this way, after pressing, the drive device 82 drives the ejector rod to move upward, thereby pushing the positioning rod 63 and the filter screen assembly upward as a whole, realizing the automatic ejection of the filter screen product. This effectively improves the automation level and production efficiency of the equipment and avoids the safety hazards and operational inconvenience caused by manual handling.

[0053] Additionally, refer to Figure 4As shown, a fourth elastic element 64 is provided between the lower end of the positioning rod 63 and the material receiving platform 7. When the positioning rod 63 moves upward, the fourth elastic element 64 is in a compressed state. In this way, the fourth elastic element 64 provides a restoring force for the positioning rod 63 to reset. Moreover, the presence of the fourth elastic element 64 can also buffer the impact force during the ejection process, ensuring the stability of the filter screen finished product ejection process.

[0054] The first, second, third, and fourth elastic elements in this application can all be springs.

[0055] Additionally, refer to Figure 3 As shown, the mobile platform 5 includes a support part 51 and a moving part 52. The support part 51 is fixedly connected to the pressing device 2, and the moving part 52 is slidably connected to the support part 51. The pressing head assembly 4 is fixedly installed on the moving part 52. A guide column 53 is fixedly provided on the support part 51, and a guide hole 71 is provided on the material receiving platform 7. The guide column 53 and the guide hole 71 cooperate with each other. In this way, the pressing head can be flexibly switched in the horizontal direction, adapting to continuous operation of multiple workstations. At the same time, the setting of the guide column 53 and the guide hole 71 ensures good guidance and positioning accuracy in the pressing process, avoiding pressing errors caused by offset. The moving part 52 can adopt a combination of cylinder and slider, or a combination of motor and slider guide rail, which are commonly available on the market. Therefore, the structure of the moving part 52 will not be described in detail in this application.
