Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic part manufacturing, in particular to a plastic part press-fitting machine and a working method thereof. BACKGROUND

[0002] In the field of plastic part manufacturing, traditional press-fitting methods rely on manual operation or semi-automatic equipment, which have problems such as low efficiency, high cost, and unstable precision. With the rapid development of automation technology, fully automated plastic part press-fitting machines have gradually become the industry demand. Existing plastic part press-fitting machines still have deficiencies in automation, production efficiency, precision control, and operation convenience, especially in multi-station collaborative work, precise posture adjustment, pre-pressing and screwing precision, etc. Therefore, there is an urgent need for a new type of high-efficiency, high-precision, and easy-to-operate fully automatic plastic part press-fitting machine to meet the needs of modern manufacturing for high efficiency and high precision production.

[0003] For example, the "Hardware Plastic Part Assembly Machine" disclosed in the Chinese patent document with application number "CN201811422860.9" includes a turntable with eight stations, and a rubber shell feeding mechanism, a PIN detection mechanism, a first spring sheet tape conveying and feeding mechanism, a first pressing mechanism, a second spring sheet tape conveying and feeding mechanism, a second pressing mechanism, an electrical detection mechanism, and a discharging mechanism installed in turn along the rotation direction of the turntable and corresponding to the station positions on the turntable.

[0004] The above-mentioned scheme realizes automatic stop of the turntable rotation to a certain angle, and each station performs its own step operation from rubber shell feeding to finished product discharging, which is automatically completed. However, the current press-fitting equipment still has the problem of incorrect product posture during transportation, which affects the immediate press-fitting action. Therefore, optimization is urgently needed. SUMMARY

[0005] The present application aims to solve the problems of low automation, low efficiency, and unstable precision of existing plastic part press-fitting machines. By introducing a multi-station turntable, an automatic posture adjustment path, and a precisely controlled pre-pressing and screwing mechanism, the entire press-fitting process can be completed without human intervention, achieving precise docking, pre-pressing, and screwing of the cartridge body and cartridge seat, thereby obtaining high efficiency, high precision, and high reliability of plastic part production, significantly improving the automation level of the manufacturing process and product quality.

[0006] To achieve the above-mentioned purposes, the present application adopts the following technical solutions:

[0007] The plastic part press fitting machine comprises a cartridge body conveying disc, a cartridge seat conveying disc, and a full-automatic press fitting mechanism that press-bonds and screws the cartridge body and the cartridge seat into one body. The cartridge body conveying disc comprises a cartridge body posture adjustment channel connected to the multifunctional press fitting mechanism, and the cartridge seat conveying disc comprises a cartridge seat posture adjustment channel connected to the multifunctional press fitting mechanism. The cartridge body posture adjustment channel and the cartridge seat posture adjustment channel respectively adjust the cartridge body and the cartridge seat to a posture for press fitting.

[0008] Through the automatic conveying disc and the press fitting mechanism, it can be ensured that each part enters the press fitting process in the correct position and state, reducing the uncertainty and error rate of manual operation. At the same time, the automatic equipment can also greatly improve the production speed and meet the needs of large-scale production. First, the automatic press fitting process can reduce manual operation, reduce labor intensity and cost. Second, the precise adjustment channel and press fitting mechanism can ensure the assembly quality of the parts and improve the durability and reliability of the products. Finally, the design of the press fitting machine allows continuous production, simplifies the production process, and shortens the production cycle. Compared with the common scheme, the press fitting machine of the present scheme has higher automation level and production efficiency. Traditional manual or semi-automatic press fitting methods may not achieve such high precision and speed. In addition, the design of the machine takes into account the precise alignment and press fitting of the parts, which is very critical in improving product quality.

[0009] As a preferred, the full-automatic press fitting mechanism comprises a multi-station turntable, which is sequentially arranged with a base station, a clamping station, a pre-pressing station, and a screwing station in the rotation direction. Each station of the multi-station turntable is provided with a clamping groove. This design makes each process flowable and automated, and each station corresponds to a specific operation step, thereby realizing the continuity and efficiency of the entire press fitting process. Through the modular and sequential station design, each work step can be more reasonably allocated, reducing unnecessary movement and waiting time. Each station has a specific function, such as the pre-pressing station that is responsible for pre-pressing the cartridge body and the cartridge seat before screwing to ensure their close fit, and the screwing station that is responsible for the final screwing to make the parts tightly combined into one body. Through the reasonable layout of the multi-station turntable, the production efficiency and operation stability are greatly improved. The orderly work flow of each station reduces the probability of errors and ensures the consistency of the press fitting quality. In addition, the improvement of automation also reduces the demand for manual operation and reduces labor costs.

[0010] As a preferred embodiment, the base station includes a transfer execution mechanism arranged above the engagement slot corresponding to the end of the cartridge posture adjustment path. The transfer execution mechanism moves the cartridge seat from the end of the cartridge posture adjustment path into the engagement slot. The function of the base station is to move the cartridge seat from the end of the cartridge posture adjustment path into the engagement slot of the multi-station turntable. This process is highly automated, ensuring that the cartridge seat can be accurately and quickly transferred to the correct position, laying the foundation for subsequent press-fitting work. The automated transfer execution mechanism can significantly improve the operation accuracy and efficiency of the machine. By precisely controlling the transfer of the cartridge seat, errors caused by manual operation can be avoided, reducing the possibility of damage or defects. In addition, automated transfer can reduce the dependence on manual labor during production, reducing production costs. Through the use of an automated transfer execution mechanism, more rapid and accurate positioning of the cartridge seat can be achieved. Such a design helps to improve overall production efficiency and reduce rework or waste caused by inaccurate positioning. At the same time, the use of an automated transfer execution mechanism also makes continuous and large-scale production of the machine possible. This solution embodies a high degree of automation and intelligence. Traditional press-fitting machines may rely more on manual operation or use simpler mechanical devices for transfer. Further optimization can be made by those skilled in the art, such as using higher precision sensors and controllers to achieve more accurate positioning. In addition, advanced technologies such as flexible robots or robotic arms can be explored to provide more flexible transfer paths and operation methods.

[0011] As a preferred embodiment, the clamping station corresponds to the end of the cartridge body posture adjustment path, and the clamping station includes a mounting mechanism arranged above the engagement slot. The mounting mechanism loads the cartridge body from the cartridge body posture adjustment path into the cartridge seat from the base station. The function of the mounting mechanism is to accurately load the cartridge body from the cartridge body posture adjustment path into the cartridge seat from the base station to ensure correct docking. By arranging the mounting mechanism at the clamping station, the docking operation of the cartridge body and the cartridge seat can be automatically completed, which not only improves efficiency but also reduces errors caused by improper manual operation. The automated clamping process helps to reduce labor intensity and improves production stability and reliability. The automated clamping station can effectively reduce the error rate during assembly and ensure accurate docking of the cartridge body and the cartridge seat. This design reduces errors and instability factors caused by manual operation, improves the quality of press-fitted products, and enhances the durability and reliability of the products. At the same time, it helps to improve the continuity and smoothness of the production process, laying the foundation for the smooth progress of subsequent processes. Compared with traditional manual or semi-automatic clamping methods, automated clamping not only saves manpower and improves production speed, but also greatly reduces the possibility of assembly errors through precise control of the clamping process. This is particularly important for the production of precision plastic parts, as any minor error can affect the performance and appearance of the final product.

[0012] As a preferred embodiment, the cartridge posture adjustment path comprises an overhead track first connected to the cartridge transfer disc; the center of gravity of the cartridge is located on the upper side, the maximum diameter of the outer edge of the middle part of the cartridge is d1, the maximum diameter of the other part of the cartridge except the outer edge of the middle part is d2, and the center width of the overhead track of the cartridge is H, wherein d2 < H < d1. The overhead track is used to adjust the posture of the cartridge based on the center of gravity distribution of the cartridge. The center of gravity of the cartridge is located on the upper side, and when the cartridge enters the overhead track, the outer edge of the middle part will naturally rest on the track. Due to the influence of the center of gravity, the cartridge will automatically adjust to a "head-up and foot-down" posture, ensuring that the cartridge can be correctly aligned and accurately matched with the cartridge seat during the subsequent compression process. In order to ensure the stability and accuracy of the cartridge during the compression process, the natural center of gravity distribution of the cartridge is utilized to effectively guide the cartridge into the correct posture without the need for additional adjustment mechanisms. This method simplifies the design of the machine, reduces the complexity of mechanical components, and also reduces the maintenance cost of the machine. Through this automatic posture adjustment, the production efficiency and compression quality can be significantly improved. Since the cartridge can automatically adjust to the correct posture, the time and cost of manual or mechanical adjustment are reduced. In addition, the automatic adjustment process also reduces the possibility of operation errors, thereby improving the consistency and reliability of the product. In the traditional compression process, additional steps or equipment may be required to ensure the correct posture of the cartridge, which not only increases the cost but also reduces the production efficiency. The design utilizes the center of gravity characteristics of the cartridge to achieve automatic posture adjustment through the overhead track, which improves the intelligent level of the machine and reduces the dependence on manual operation. Those skilled in the art can further optimize the structure of the cartridge posture adjustment path, such as introducing an automatic adjustment system to adjust the width of the track in real time according to the specific size of the cartridge to adapt to different specifications of parts.

[0013] As a preferred embodiment, the maximum diameter of the external thread provided on the lower part of the outer edge of the middle part of the cartridge is d3, and the inner diameter of the convex ring provided on the port of the cartridge seat is d4, wherein d4 < d3, and the external thread of the cartridge is compressed and passes through the convex ring of the cartridge seat at the pre-compression station. This design ensures that the external thread of the cartridge can be smoothly compressed into the convex ring of the cartridge seat, thereby achieving accurate fixation and combination of the cartridge and the cartridge seat. By accurately controlling the size relationship between the external thread of the cartridge and the convex ring of the cartridge seat, it can be ensured that the cartridge can be closely combined with the cartridge seat during compression at the pre-compression station, forming a stable connection. This close connection not only improves the durability and reliability of the parts, but also helps to reduce failures or damages caused by loose connections. By accurately controlling the size relationship, the stability and reliability during the compression process can be ensured. The accurate matching of the cartridge and the cartridge seat reduces the error during the assembly process and improves the pass rate of the product. At the same time, this close connection method also helps to improve the overall structural strength of the plastic parts and prolong their service life.

[0014] As a preferred, the warehouse body posture adjustment channel further includes a conveying channel connected after the overhead track, and the conveying channel includes an outwardly inclined bottom plate, and the outer side of the outwardly inclined bottom plate is provided with a first baffle, and the first baffle includes a hollow section, the height of the hollow section is greater than d1, and the height of the hollow section is less than the height of the warehouse body. The warehouse body posture adjustment channel and the warehouse seat posture adjustment channel are both spiral double-row slides. The key to the design of the warehouse body posture adjustment channel in the plastic part press fitting machine is to ensure that all the warehouse bodies are in the correct vertical state and orientation when being conveyed to the clamping station through the outwardly inclined bottom plate and the hollow section of the first baffle. This design is crucial because it directly affects whether the warehouse body and the warehouse seat can be correctly docked and press fitted together. Both the warehouse body and the warehouse seat are cylindrical structures, so they must be kept in a vertical state to ensure the quality of press fitting. Through the design of the hollow section, warehouse bodies that have not been adjusted to a vertical state can be screened out and rolled away from the conveying channel, starting the conveying process again from the starting position of the conveying disc. In this way, only warehouse bodies with correct postures can smoothly pass through the conveying channel and reach the clamping station. This process makes full use of the natural characteristics of the cylindrical warehouse body, which will naturally roll down under the influence of the outwardly inclined bottom plate in a vertical state. This screening mechanism ensures that all warehouse bodies reaching the clamping station are in the correct vertical state and orientation, thereby significantly improving the press fitting accuracy and efficiency. By automatically screening and correcting the posture of the warehouse body, the need for manual inspection and adjustment is reduced, the automation level of the production line is improved, production costs are reduced, and the consistency and reliability of the product are ensured. Traditional conveying systems may not be able to automatically screen and correct the posture of the warehouse body, relying on manual inspection and adjustment, which not only is inefficient, but also is prone to errors and quality problems due to human factors. However, through the ingenious application of the hollow section, this design achieves automatic screening and correction of the warehouse body posture, significantly improving the intelligent level and production efficiency of the press fitting machine.

[0015] As a preferred, the warehouse seat posture adjustment channel includes an outwardly inclined conveying channel, which includes an orientation adjustment section and a screening section lower than the orientation adjustment section; an adjustment hook is suspended at the boundary between the orientation adjustment section and the screening section, the adjustment hook can hook the warehouse seat with the mouth facing forward and rotate it to fall into the screening section while keeping the warehouse seat bottom upright; the outer side of the screening section includes a second baffle provided with a hollow section. By accurately designing the orientation adjustment section and the screening section, the posture of the warehouse seat can be effectively adjusted to achieve the correct orientation required by the clamping station. The design of the adjustment hook cleverly uses the weight and mechanical structure of the warehouse seat to achieve automatic adjustment, reducing the need for additional power systems or manual intervention. The hollow section of the second baffle is similar to the design of the first baffle, ensuring the stability and accuracy of the posture of the warehouse seat during conveying. Through the automatic posture adjustment process, production efficiency is improved, and the scrap rate caused by incorrect posture is reduced. Automatic posture adjustment not only reduces the need for manual operation, but also improves the accuracy and stability of the entire press fitting process, thereby improving the quality of the final product.

[0016] As a preferred, the multi-station turntable further comprises a discharging station, which includes a blowing tube arranged inside the clamping groove, and a receiving body arranged outside the clamping groove. Through the design of the blowing tube, the completed plastic parts can be gently pushed out, avoiding physical damage to the parts. This gentle pushing method is particularly suitable for delicate or fine plastic parts, ensuring the integrity and quality of the parts during the conveying process. In addition, the arrangement of the receiving body helps to collect and organize the output parts, facilitating subsequent processing or packaging, improving the automation and efficiency of production. The degree of automation of the press-fitting machine is improved, the need for manual intervention is reduced, and the errors and damage in the production process are also reduced. The coordinated work of the blowing tube and the receiving body ensures the smooth and safe output of the parts, optimizes the production process, and improves the overall work efficiency of the production line.

[0017] The application also discloses a working method of the plastic part press-fitting machine.

[0018] S1. Place the bin body and the bin seat on the bin body conveying disc and the bin seat conveying disc, respectively;

[0019] S2. Adjust the bin body and the bin seat to the waiting press-fitting posture through the bin body posture adjusting channel and the bin seat posture adjusting channel, respectively;

[0020] S3. Move the bin seat from the end of the bin seat posture adjusting channel to the clamping groove of the multi-station turntable using the transfer execution mechanism;

[0021] S4. In the clamping station, the bin body is clamped into the bin seat by the installation mechanism to ensure correct docking;

[0022] S5. In the pre-pressing station, the bin body and the bin seat are pre-pressed by the automatic pressing mechanism;

[0023] S6. In the screwing station, the final screwing operation is performed to tightly connect the bin body and the bin seat;

[0024] S7. The plastic parts after completing the press-fitting are output through the multi-station turntable and enter the next production link.

[0025] The method realizes the automation and precise control of the whole pressing process. The first step of the working method is to place the cartridge body and cartridge seat on the cartridge body conveying disc and the cartridge seat conveying disc respectively (step S1). This step is the basis of the whole pressing process, ensuring the correct placement of the parts and the smooth progress of the subsequent operations. Then, the cartridge body and cartridge seat are adjusted to the pressing posture through the cartridge body posture adjustment channel and the cartridge seat posture adjustment channel (step S2). These two steps are key technical links, which fully utilize the overhead track and conveying channel design mentioned in the previous claims to ensure the posture adjustment and precise docking of the parts. Step S3 involves using a transfer execution mechanism to move the cartridge seat from the end of the cartridge seat posture adjustment channel to the clamping slot of the multi-station turntable. This step embodies the high efficiency and accuracy of the automatic pressing mechanism, reducing the intervention of manual operation and improving production efficiency through precise positioning and movement. Step S4 is in the clamping station, where the cartridge body from the cartridge body posture adjustment channel is installed into the cartridge seat from the self-base station, ensuring correct docking. This step is crucial to ensure the precise fit of the cartridge body and cartridge seat, laying the foundation for subsequent pressing. Step S5 is in the pre-pressing station, where the automatic pressing mechanism pre-presses the cartridge body and cartridge seat. Pre-pressing is an important step to ensure the tight combination of plastic parts, and through appropriate pressure control, it can ensure the tight combination between parts, improving the quality and durability of the product. Step S6 is in the final screwing station, which performs the final screwing operation to tightly connect the cartridge body and cartridge seat. This step is the climax of the whole pressing process, which completes the final forming of the plastic parts through precise screwing operation, embodying the technical advantages and production capacity of the pressing machine. Finally, step S7 outputs the completed plastic parts through the multi-station turntable, entering the next production link. This step marks the end of a single production cycle, and also provides convenience for the subsequent processing and packaging of the parts.

[0026] By clearly defining each step, the consistency and consistency of the pressing process are ensured, reducing human error and production delay. Such process design helps to improve production efficiency, ensure product quality, and facilitate monitoring and management of the production process. Through the automatic and precise control of the pressing process, production efficiency can be greatly improved, waste rate can be reduced, and product consistency and reliability can be ensured. The automated process reduces the dependence on manual operation, reduces labor costs, and improves production flexibility and response speed. Traditional methods may rely on manual operation or semi-automatic equipment, which is not only inefficient but also prone to errors. This method realizes the automation and precise control of the whole process by clearly defining and detailing each step, significantly improving production efficiency and product quality.

DETAILED DESCRIPTION

[0038] The present application will be further described below in conjunction with the drawings and specific embodiments. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements with the same or similar functions throughout.

[0039] Example 1

[0040] As Figure 1 , 2As shown, a plastic part press fitting machine includes: a warehouse body conveying disc 1; a warehouse seat conveying disc 2; a full-automatic pressing mechanism 3, which presses and rotates the warehouse body 100 and the warehouse seat 200 to become an integral whole. Among them, the warehouse body conveying disc includes a warehouse body posture adjusting channel 14 connected to the multifunctional pressing mechanism, and the warehouse seat conveying disc includes a warehouse seat posture adjusting channel 17 connected to the multifunctional pressing mechanism; wherein the warehouse body posture adjusting channel and the warehouse seat posture adjusting channel respectively adjust the warehouse body and the warehouse seat to the posture to be pressed and fitted. The full-automatic pressing mechanism includes a multi-station turntable 4, which is sequentially arranged in the rotation direction and includes a base station 5, a clamping station 7, a pre-pressing station 6 and a rotating station 8; each station of the multi-station turntable is provided with a clamping groove 41. The multi-station turntable further includes a discharging station 23, which includes a blowing pipe 24 arranged on the inner side of the clamping groove, and a receiving body is arranged on the outer side of the clamping groove.

[0041] Through the automatic conveying disc and the pressing mechanism, it can be ensured that each part can enter the pressing process in the correct position and state, reducing the uncertainty and error rate of manual operation. At the same time, the automatic equipment can also greatly improve the production speed and adapt to the needs of large-scale production. First, the automatic pressing process can reduce human operation, reduce labor intensity and cost. Second, the precise adjusting channel and pressing mechanism can ensure the assembly quality of the parts and improve the durability and reliability of the products. Finally, the design of the pressing machine allows continuous production, simplifies the production process and shortens the production cycle. Compared with the common scheme, the pressing machine of the present scheme has higher automation level and production efficiency. Traditional manual or semi-automatic pressing methods may not be able to achieve such high precision and speed. This design makes each process flowable and automated, and each station corresponds to a specific operation step, thereby realizing the continuity and efficiency of the entire pressing process. Through the modular and sequential station design, each work step can be more reasonably allocated, reducing unnecessary movement and waiting time. Each station has a specific function, such as the pre-pressing station responsible for pre-pressing the warehouse body and the warehouse seat before rotation to ensure their close fit; and the rotating station is responsible for the final rotation and rotation to make the parts tightly combined into a whole. Through the reasonable layout of the multi-station turntable, the production efficiency and operation stability are greatly improved. The orderly work flow of each station reduces the probability of error and ensures the consistency of the pressing quality. In addition, the improvement of automation also reduces the demand for manual operation and reduces labor costs.

[0042] In this embodiment, the base station includes a transfer execution mechanism 51 corresponding to the upper part of the clamping groove. The transfer execution mechanism adjusts the position of the cartridge seat from the end of the cartridge seat posture adjustment path to the clamping groove. The function of the base station is to move the cartridge seat from the end of the cartridge seat posture adjustment path to the clamping groove of the multi-station turntable. This process has a high degree of automation, ensuring that the cartridge seat can be accurately and quickly transferred to the correct position, laying the foundation for subsequent press-fitting work. The automated transfer execution mechanism can significantly improve the operation accuracy and efficiency of the machine. By precisely controlling the transfer of the cartridge seat, errors caused by manual operation can be avoided, reducing the possibility of damage or defects. In addition, automated transfer can reduce the dependence on manual labor during production, reducing production costs. Through the use of an automated transfer execution mechanism, more rapid and accurate positioning of the cartridge seat can be achieved. Such a design helps to improve overall production efficiency and reduce rework or waste caused by inaccurate positioning. At the same time, the use of an automated transfer execution mechanism also makes continuous and large-scale production of the machine possible. This solution embodies a high degree of automation and intelligence. Traditional press-fitting machines may rely more on manual operation or use simpler mechanical devices for transfer. Further optimization can be performed by those skilled in the art, such as the use of higher precision sensors and controllers to achieve more accurate positioning. In addition, advanced technologies such as flexible robots or robotic arms can be explored to provide more flexible transfer paths and operation methods.

[0043] The clamping station corresponds to the end of the cartridge body posture adjustment path and includes an installation mechanism 71 arranged above the clamping groove. The installation mechanism loads the cartridge body from the cartridge body posture adjustment path into the cartridge seat from the base station. The function of the installation mechanism is to accurately load the cartridge body from the cartridge body posture adjustment path into the cartridge seat moved from the base station to ensure correct docking. By providing an installation mechanism at the clamping station, the docking operation of the cartridge body and cartridge seat can be automatically completed, which not only improves efficiency but also reduces errors caused by improper manual operation. The automated clamping process helps to reduce labor intensity and improves production stability and reliability. The automated clamping station can effectively reduce the error rate during assembly and ensure accurate docking of the cartridge body and cartridge seat. This design reduces errors and instability factors caused by manual operation, improves the quality of press-fitted products, and enhances the durability and reliability of the products. At the same time, it helps to improve the continuity and smoothness of the production process, laying the foundation for the smooth progress of subsequent processes. Compared with traditional manual or semi-automatic clamping methods, automated clamping not only saves manpower and improves production speed, but also greatly reduces the possibility of assembly errors through precise control of the clamping process. This is particularly important for the production of precision plastic parts, as any minor error can affect the performance and appearance of the final product.

[0044] As Figure 3 , 4As shown, the posture adjusting path of the cartridge body includes an overhead track 9 first connected to the cartridge body conveying disc; the center of gravity of the cartridge body is upward, the maximum diameter of the outer edge 101 of the middle part of the cartridge body is d1, the maximum diameter of the other part of the cartridge body except the outer edge of the middle part is d2, and the center width of the overhead track 9 of the cartridge body is H, wherein d2 The maximum diameter of the outer thread 15 arranged at the lower part of the outer edge of the middle part of the cartridge body is d3, the inner diameter of the convex ring 16 arranged at the port of the cartridge seat is d4, wherein d4

[0045] The center of gravity of the cartridge body is located at the top center, and when the cartridge body enters the overhead track, the middle outer edge will naturally rest on the track. Due to the influence of the center of gravity, the cartridge body will automatically adjust to a "head up and feet down" posture, ensuring that during the subsequent pressing process, the cartridge body can be correctly aligned and accurately matched with the cartridge seat. To ensure the stability and accuracy of the cartridge body during the pressing process, by utilizing the natural center of gravity distribution of the cartridge body, the cartridge body can be effectively guided into the correct posture without the need for additional adjustment mechanisms. This method simplifies the design of the machine, reduces the complexity of mechanical components, and also reduces the maintenance cost of the machine. Through this automatic posture adjustment, production efficiency and pressing quality can be significantly improved. Since the cartridge body can automatically adjust to the correct posture, the time and cost of manual or mechanical adjustment are reduced. In addition, the automatic adjustment process also reduces the possibility of operation errors, thereby improving the consistency and reliability of the product. In traditional pressing processes, additional steps or equipment may be required to ensure the correct posture of the cartridge body, which not only increases the cost but also reduces the production efficiency. The design utilizes the center of gravity characteristics of the cartridge body to achieve automatic posture adjustment through the overhead track, which improves the intelligent level of the machine and reduces the dependence on manual operation.This process takes full advantage of the natural characteristics of the cartridge cylinder, which naturally rolls down under the influence of the canting bottom plate in the vertical state. This screening mechanism ensures that all cartridges reaching the clamping station are in the correct vertical state and orientation, greatly improving the precision and efficiency of the press-fit. By automatically screening and correcting the cartridge posture, the need for manual inspection and adjustment is reduced, improving the automation level of the production line, reducing production costs, and ensuring product consistency and reliability. Traditional conveying systems may not automatically screen and correct the cartridge posture, relying on manual inspection and adjustment, which not only is inefficient, but also is prone to human error and quality problems. This design, through the ingenious application of the hollow section, realizes the automatic screening and correction of the cartridge posture, significantly improving the intelligent level and production efficiency of the press-fit machine.

[0046] In addition, the cartridge seat posture adjustment path includes a canting conveying path 18, which includes an orientation adjustment section 19 and a screening section 20 below the orientation adjustment section; an adjustment hook 21 is suspended at the boundary between the orientation adjustment section and the screening section, which can hook the cartridge seat with the mouth facing forward and rotate it to fall into the screening section while maintaining the upright state with the bottom of the cartridge seat facing down; the outer side of the screening section includes a second baffle 22 with a hollow section. By precisely designing the orientation adjustment section and the screening section, the posture of the cartridge seat can be effectively adjusted to achieve the correct orientation required by the clamping station. The design of the adjustment hook cleverly utilizes the weight of the cartridge seat and the mechanical structure to achieve automatic adjustment, reducing the need for additional power systems or manual intervention. The hollow section of the second baffle is similar to the design of the first baffle, ensuring the stability and accuracy of the cartridge seat during the conveying process. Through the automatic posture adjustment process, production efficiency is improved, and the scrap rate caused by incorrect posture is reduced. Automatic posture adjustment not only reduces the need for manual operation, but also improves the accuracy and stability of the entire press-fit process, thereby improving the quality of the final product.

[0047] In terms of cartridge conveying disc, a cartridge posture adjustment path is designed, which is connected to the full-automatic press-fit mechanism. This adjustment path ensures that the cartridge enters the press-fit process in the correct posture. The adjustment path adopts an overhead track, and the center width H of the track is designed to be between the maximum outer diameter d1 of the middle part of the cartridge and the maximum outer diameter d2 of other parts of the cartridge. Among them, d2 < H < d1, this design helps to take advantage of the feature that the center of gravity of the cartridge is high, ensuring the stability and alignment accuracy of the cartridge on the track. In the pre-pressing station, the matching design of the maximum outer diameter d3 of the cartridge thread and the inner diameter d4 of the convex ring of the cartridge seat (d4 < d3) ensures that the cartridge thread can be smoothly pressed into the convex ring of the cartridge seat, and in the screwing station, the cartridge thread and the inner thread 25 of the cartridge seat complete the connection.

[0048] The cartridge seat transfer disc is also designed with a cartridge seat posture adjustment channel, which is connected to the full-automatic pressing mechanism. This adjustment channel is responsible for adjusting the cartridge seat to the posture for pressing. To ensure the accurate alignment of the cartridge seat, an outwardly inclined transfer channel is designed, which consists of a direction adjustment section and a screening section. The adjustment hook suspended at the boundary can hook and rotate the cartridge seat according to its weight and structural characteristics, ensuring that the cartridge seat stands upright with the bottom facing down.

[0049] For the full-automatic pressing mechanism, the core component is the multi-station turntable. The design of the turntable allows the cartridge body and cartridge seat to pass through each station in a predetermined sequence. In the cartridge seat station, the transfer execution mechanism is responsible for moving the cartridge seat from the end of the cartridge seat posture adjustment channel to the clamping groove. In the clamping station, the installation mechanism installs the cartridge body from the cartridge body posture adjustment channel into the cartridge seat. The arrangement of these two stations not only ensures the accurate alignment of the cartridge body and cartridge seat, but also improves the automation level of the pressing process.

[0050] In addition, the pre-pressing station is set to apply appropriate pressure to the cartridge body and cartridge seat before final screwing. This step is necessary because it can ensure uniform distribution and tight coupling of the plastic material during the screwing process. Finally, in the screwing station, the cartridge body and cartridge seat are tightly coupled to form the final plastic part.

[0051] In the discharge station, a blowing pipe is designed to gently push out the completed plastic parts. This design takes into account the sensitivity and fragility of the plastic parts, avoiding damage to the parts through non-contact means. At the same time, the storage body set outside the clamping groove is used to collect the output plastic parts, ensuring the orderly output and subsequent processing of the parts.

[0052] In addition to the above main components, the entire pressing machine also includes a precise control system for monitoring and adjusting the working state of each component. For example, sensors can monitor the posture of the cartridge body and cartridge seat during the transfer process in real time, and the control system can automatically adjust the parameters of the transfer channel according to the feedback of the sensors to ensure accurate alignment of the parts.

[0053] In summary, the design of this plastic part pressing machine realizes efficient, accurate and automated production of plastic parts through precise component size matching, automated posture adjustment and pressing process, and intelligent control system. This scheme not only improves production efficiency and reduces labor costs, but also improves product quality and consistency by reducing human error. In addition, this scheme has good scalability and adaptability, and can be adjusted and optimized according to different production needs.

[0054] After comprehensive analysis, the overall design of this embodiment needs to consider the impact on improving production efficiency, ensuring product quality, and operating safety. The core advantage of this machine lies in its high degree of automation, which can realize the process of part clamping, pre-pressing and screwing almost without human intervention. The following is a further analysis of the design of the press machine.

[0055] First of all, from the structure and connection method, the design of the press machine focuses on ensuring the smooth transfer of parts between various stations. The design of the multi-station carousel allows the parts to go through the positioning, pre-pressing and screwing process in turn, which not only improves the production efficiency, but also reduces the error in the production process. For example, there is a specific proportional relationship between the diameter D of the multi-station carousel and the size d5, d6 of the bin body and bin seat, which ensures that the parts can be accurately aligned during rotation. This accurate alignment design is a prerequisite for ensuring the quality of the press. In the pre-pressing station, the full-automatic press mechanism applies appropriate pre-pressing force through a precise pressure control system. The design of this pressure system allows precise control of the pressure during pre-pressing, whether it is through hydraulic, pneumatic or electric means. Precise control of pre-pressing force is crucial to the quality of plastic part press, as it directly affects the bonding strength and durability of the part. In the design, this embodiment considers the elastic modulus, yield strength and creep characteristics of the plastic material under long-term load to determine the optimal pre-pressing range. The design of the screwing station also reflects the importance of precise control. In this step, the automatic screwing mechanism screws the bin body and bin seat together to form the final plastic part. The design of the screwing mechanism needs to consider the screwing speed, screwing angle and screwing torque to ensure the uniformity of the screwing process and the tightness of the part. This precise control of the screwing process can effectively prevent damage to the part or insufficient structural strength due to improper screwing.

[0056] In addition, for the problem of stress concentration that may occur during the press process, this embodiment also carries out detailed analysis and optimization. For plastic materials, stress concentration is inevitable during the press process, which may affect the long-term performance and reliability of the part. This embodiment reduces the impact of stress concentration by optimizing the structural design of the part and adjusting the press parameters such as pressure, speed and temperature. For example, by optimizing the design of the bin body and bin seat, increasing the stress dispersion area can effectively reduce the stress concentration phenomenon.

[0057] In addition, in terms of safety, the design of the press machine takes into account the safety of the operators. For example, for the operation of the full-automatic press mechanism, this embodiment designs an emergency stop device and safety protection measures to prevent accidents during operation. In addition, for high-pressure, high-speed or high-temperature working environments, this embodiment can take appropriate protective measures such as setting up safety covers, pressure relief valves and temperature monitoring systems.

[0058] The design of this press machine aims to improve production efficiency, ensure product quality, reduce cost, and ensure the simplicity and safety of operation. The working method is as follows:

[0059] First, the operation process starts from the loading stage of the cartridge body and cartridge seat. The operator places the cartridge body and cartridge seat to be pressed in the specified direction on the respective conveying disc. At this time, the conveying disc will send these parts to the posture adjustment channel. The design of the posture adjustment channel allows the cartridge body and cartridge seat to automatically adjust to the correct posture during transmission, which is the key to the success of the subsequent pressing process. For example, the inclination angle α of the cartridge body is monitored in real time by a sensor and adjusted accurately by a servo motor to ensure that it is correctly aligned with the cartridge seat in the next operation.

[0060] Next, the cartridge body and cartridge seat after posture adjustment are conveyed to the preset station. In the clamping station, the high-precision positioning system ensures that the cartridge body and cartridge seat are perfectly aligned before clamping. At this time, the clamping mechanism gently presses the cartridge body into the cartridge seat, and the pressure p needs to be controlled to be less than the yield strength σy of the material to avoid damage to the material. The action of the clamping mechanism is controlled by a precise control system to ensure uniform distribution of the pressing force.

[0061] In the pre-pressing station, the fully automatic pressing mechanism applies a certain amount of pre-pressing to ensure the preliminary close combination of the cartridge body and cartridge seat. During the pre-pressing process, the pressing force p1 needs to be accurately controlled between the elastic limit σe and the yield strength σy of the material to achieve effective pre-pressing without causing permanent deformation of the material. In addition, the pre-pressing time t1 is also accurately set by the control system to ensure that the material reaches the required bonding strength after pre-pressing.

[0062] In the screwing station, the pressing mechanism performs the final screwing of the cartridge body and cartridge seat. During the screwing process, the screwing torque τ is monitored in real time by a precise torque sensor and kept within a safe range by the control system to prevent accidental damage during screwing. The screwing speed v2 and the screwing angle θ are optimized according to the characteristics of the material and the design requirements to ensure the efficiency and quality of the screwing process.

[0063] During the entire pressing process, the press machine is also equipped with a fault diagnosis and alarm system. Once any abnormal condition is detected, such as sensor readings exceeding the preset range, the control system will automatically stop the pressing process and issue an alarm. This not only ensures the safety of the operation, but also ensures the controllability of the product quality.

[0064] In addition, the design of the press machine also considers the convenience of maintenance and replacement. For example, key components such as sensors, motors and control systems are designed to be modular, making it easy to replace and maintain. At the same time, the operation interface of the press machine is designed to be simple and intuitive, and the operator can easily set parameters and monitor production status through the touch screen.

[0065] In actual production, the press machine can be widely used in the manufacturing of plastic parts for automobile parts, household appliances, and electronic equipment. For example, in the automotive industry, it can be used to manufacture plastic covers for engines and interior parts. In the field of household appliances, it can be used to manufacture plastic casings and parts for washing machines and refrigerators. Through precise control and automated production, the press machine can greatly improve production efficiency, reduce labor costs, and ensure product consistency and reliability.

[0066] Example 2

[0067] In this example, in addition to the technical points and factors considered in Example 1, other technical points and factors in the application of the device are considered:

[0068] Material properties: Different plastic materials have different physical and chemical properties, such as thermal stability, impact resistance, etc. Before pressing, the properties of the material must be fully understood, and the pressing parameters must be adjusted according to these properties.

[0069] Introduce intelligent algorithms: through machine learning algorithms, real-time optimization of pressing parameters is carried out to adapt to different production needs and material properties.

[0070] Increase the degree of automation: by introducing more automated equipment, such as robots, further improve production efficiency and reduce human intervention.
