Description

Technical Field

[0001] This application relates to the field of fully automated processing, specifically to a sheet metal hot pressing assembly equipment and method for shaver plug fixing parts. Background Technology

[0002] In plug-in shavers, the plug securing assembly typically consists of a plastic fixing part and a sheet metal part. The plastic part provides insulation and structural support and houses the mounting posts, while the sheet metal part, as a conductive component, forms an electrical connection path after assembly with the charging pin. Existing solutions often employ thermoforming, where the plastic mounting posts undergo thermoplastic deformation under heat and pressure, forming a flanged structure to enclose and secure the sheet metal part, preventing it from loosening or detaching.

[0003] Currently, the assembly and hot-pressing processes of the aforementioned components are generally completed manually: operators pick up the plastic and sheet metal parts one by one, confirm the orientation, place the sheet metal parts on the mounting posts, and then place the components into a manual hot press to complete the fixing. This method has the following drawbacks: Firstly, in the material supply and pre-assembly stages, sheet metal and plastic parts rely on manual handling, orientation identification, and placement, lacking automated supply and positioning mechanisms. Sheet metal parts have directional requirements, and manual operation easily leads to problems such as reverse placement, misalignment, and omissions, making it difficult to ensure accurate placement on the mounting post each time. Secondly, in the hot-pressing stage, the pressure and temperature of the manual hot press rely on manual control. Long-term repetitive operation easily leads to inconsistent parameters, resulting in unstable forming quality of the flanged structure, difficulty in guaranteeing locking strength and dimensional consistency, and potential quality risks such as poor contact and fluctuations in charging performance. Thirdly, regarding process coordination, pre-assembly, hot-pressing, and material unloading are executed sequentially, and material transfer between workstations relies on manual handling, making it impossible to achieve parallel operation of pre-assembly and hot-pressing, resulting in low overall production efficiency.

[0004] Therefore, there is a need for sheet metal hot pressing assembly equipment and methods that can automatically feed sheet metal and plastic parts, accurately assemble and position them to complete accurate pre-assembly, and automatically unload the parts, so as to reduce reliance on manual labor and improve assembly accuracy, hot pressing consistency and production efficiency. Summary of the Invention

[0005] This application provides a sheet metal hot pressing assembly equipment and processing method for shaver plug fixing parts, in order to solve the technical problems of low feeding and pre-assembly positioning accuracy of sheet metal and plastic parts under the existing manual assembly mode, inconsistent pressure and temperature parameters of manual hot pressing leading to unstable forming quality of the flanged structure, and low production efficiency caused by the inability to operate in parallel due to the serial execution of each process.

[0006] This application adopts the following technical solution: a sheet metal hot pressing assembly device for a shaver plug fixing component, wherein the shaver plug fixing component is assembled from a sheet metal part onto a mounting post of a plastic part and fixed by hot pressing. The assembly device includes a base plate and a feeding mechanism and a control box disposed on the base plate for feeding the sheet metal part and the plastic part one by one, and further includes: The pre-assembly trough is set on the base plate and located downstream of the feeding mechanism. The pre-assembly trough is equipped with a positioning structure that matches the shape of the plastic parts and sheet metal parts. After the plastic parts and sheet metal parts are fed into the pre-assembly trough in sequence, they are automatically positioned to the predetermined assembly position by means of the positioning structure to form a sheet metal assembly. The workstation switching mechanism includes a positioning frame fixed to a base plate, a rotary cylinder mounted on the upper end of the positioning frame, and a rotating plate driven by the rotary cylinder. A pre-assembly trough is mounted on the rotating plate, and the rotary cylinder drives the rotating plate to rotate, thereby switching the pre-assembly trough between an assembly station and a conveying station. The indexing hot pressing mechanism includes a turntable rotatably mounted on a base plate, a motor that drives the turntable to rotate in an indexing manner, multiple hot pressing grooves evenly distributed along the circumference on the upper surface of the turntable, and a hot press machine mounted on one side of the turntable. The multiple hot pressing grooves pass through the loading station, the hot pressing station, and the unloading station in sequence as the turntable rotates in an indexing manner. The hot press machine is used to apply a preset pressure and temperature to the sheet metal assembly in the hot pressing groove that reaches the hot pressing station to cause the mounting column to undergo thermoplastic deformation to form a flange structure, thereby locking the sheet metal part to form a finished part.

[0007] Furthermore, the feeding mechanism includes a sheet metal feeding unit and a plastic feeding unit; the sheet metal feeding unit includes a vibratory feeder 1, a separator linear vibrating track 1 connected to the discharge end of the vibratory feeder 1, and a pick-and-place execution component 1 for picking up sheet metal parts from the separator linear vibrating track 1 and placing them into the pre-assembly trough; the plastic feeding unit includes a vibratory feeder 2, a separator linear vibrating track 2 connected to the discharge end of the vibratory feeder 2, and a pick-and-place execution component 2 for picking up plastic parts from the separator linear vibrating track 2 and placing them into the pre-assembly trough before the sheet metal parts.

[0008] Furthermore, the pick-and-place execution component one includes a bracket one mounted on the base plate and a three-axis pneumatic slide assembly mounted on the bracket one. The three-axis pneumatic slide assembly includes a first horizontal pneumatic slide that slides along a first horizontal direction, a second horizontal pneumatic slide that is located at the sliding end of the first horizontal pneumatic slide and slides along a second horizontal direction, and a vertical pneumatic slide one that is located at the sliding end of the second horizontal pneumatic slide and slides along a vertical direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. A suction cup is provided at the end of the vertical pneumatic slide one, and the suction cup picks up the sheet metal parts by vacuum adsorption.

[0009] Furthermore, the second pick-and-place execution component includes a bracket two mounted on the base plate and a two-axis pneumatic slide assembly mounted on the bracket two. The two-axis pneumatic slide assembly includes a third horizontal pneumatic slide that slides in the horizontal direction and a vertical pneumatic slide two that is located at the sliding end of the third horizontal pneumatic slide and slides in the vertical direction. The end of the vertical pneumatic slide two is provided with a chuck one, which picks up plastic parts by mechanical clamping.

[0010] Furthermore, it also includes a material transfer and placement assembly, which includes a second positioning frame fixed on the base plate, a horizontal pneumatic slide table for material transfer set on the upper end of the second positioning frame, a vertical pneumatic slide table for material transfer set on the sliding end of the horizontal pneumatic slide table for material transfer, and a second chuck set on the end of the vertical pneumatic slide table for material transfer. The second chuck is used to clamp the sheet metal assembly in the pre-assembly groove and place it into the hot press groove located at the loading station.

[0011] Furthermore, the indexing hot pressing mechanism also includes a fixed block on the base plate, a roller rotatably mounted on the upper end of the fixed block and rolling in contact with the bottom surface of the turntable to provide auxiliary support for the turntable, and a photoelectric sensor mounted on the side of the fixed block. The photoelectric sensor is used to detect the angular position of the turntable and send the detection signal to the PLC control box to control the start and stop of the motor.

[0012] Furthermore, it also includes a feeding mechanism, which includes a feeding rotary cylinder fixed to the base plate, a plate fixed to the output end of the feeding rotary cylinder, a feeding vertical cylinder fixed to the plate, and a feeding suction cup set at the output end of the feeding vertical cylinder; the feeding rotary cylinder drives the plate to rotate so that the feeding suction cup switches between above the hot pressing groove and above the feeding track located at the feeding station, and the feeding vertical cylinder drives the feeding suction cup to rise and fall to pick up and release the finished parts.

[0013] Furthermore, two pre-assembly slots are symmetrically arranged on the rotating plate along its rotation center. When one pre-assembly slot is located at the assembly station, the other pre-assembly slot is located at the conveying station, so that the pre-assembly operation and the material conveying operation are performed alternately and in parallel.

[0014] Furthermore, the positioning structure includes a cavity adapted to the outline of the plastic part at the bottom of the pre-assembly groove, and a guide surface above the cavity for guiding the sheet metal part to fall in a predetermined direction and align with the mounting post; the upper end of the sheet metal part is provided with a mounting hole adapted to the mounting post.

[0015] This application also discloses the following technical solution: a method for processing a shaver plug fixing part, comprising the following steps: S1. Dual-path feeding: Sheet metal parts and plastic parts are conveyed one by one in an orderly manner through their respective feeding mechanisms; S2. Positioning and pre-assembly: First, the plastic parts are mechanically clamped and fed into the pre-assembly material slot. Then, the sheet metal parts are placed on the mounting posts of the plastic parts by vacuum adsorption. The two parts are automatically positioned by the positioning structure to form a sheet metal assembly. S3, Station Switching and Material Transfer: The rotary cylinder drives the pre-assembly trough to switch from the assembly station to the conveying station, transferring the sheet metal assembly to the hot pressing trough located at the loading station on the turntable; S4, Indexing Hot Press: The motor drives the turntable to rotate in an indexing manner so that the hot pressing groove reaches the hot pressing station. The hot press uses preset pressure and temperature to hot press the mounting column to make it thermoplastic deformation and form a flange structure to lock the sheet metal parts and form the finished parts. S5. Automatic unloading: The turntable continues to rotate to the unloading station, and the finished part is taken out and released into the unloading track; During the execution of steps S3 and S4, steps S1 and S2 are executed synchronously after the other pre-assembly tank or the same pre-assembly tank is reset, so that the pre-assembly operation and the hot pressing operation can be carried out in parallel.

[0016] Compared with the prior art, the present invention has the following advantages: First, in terms of material supply and pre-assembly positioning, this invention replaces the manual handling of picking up and identifying directions by setting up sheet metal feeding units and plastic feeding units to transport sheet metal parts and plastic parts one by one in an orderly manner. At the same time, a positioning structure adapted to the shape of plastic parts and sheet metal parts is set in the pre-assembly material groove. The positioning structure includes a cavity adapted to the outline of the plastic parts and a guide surface for guiding the sheet metal parts to fall in along a predetermined direction and align with the mounting post. This allows the plastic parts and sheet metal parts to automatically fall to the predetermined assembly position to form a sheet metal assembly after being fed into the pre-assembly material groove in sequence, eliminating problems such as reverse placement, misalignment, and omissions caused by incorrect direction identification or placement deviation in manual assembly, and improving the pre-assembly positioning accuracy.

[0017] Secondly, regarding the quality of hot pressing, this invention employs an indexing hot pressing mechanism. Through a rotary table with multiple hot pressing grooves arranged in an indexing pattern, and a hot press located on one side of the rotary table, the hot press applies preset pressure and temperature to the mounting posts of the plastic parts in the sheet metal assembly that arrives at the hot pressing station. This causes the mounting posts to undergo thermoplastic deformation, forming a flange structure to secure the sheet metal part. The pressure and temperature parameters of the hot press are preset and adjusted through a control box, ensuring consistent process conditions for each hot pressing operation. This solves the problems of unstable flange structure forming quality and difficulty in guaranteeing locking strength and dimensional consistency caused by manual hot pressing methods where pressure and temperature parameters rely on manual control and repeated operations over long periods lead to inconsistent parameters.

[0018] Third, in terms of production efficiency, this invention uses a station switching mechanism to switch the pre-assembly trough between the assembly station and the conveying station. Two pre-assembly troughs are symmetrically arranged along the rotation center on the rotating plate. When one pre-assembly trough is in the assembly station for pre-assembly operations, the other pre-assembly trough is in the conveying station for material transfer operations, so that the pre-assembly and material transfer operations are executed alternately and in parallel. At the same time, the multiple hot pressing troughs of the indexing hot pressing mechanism pass through the loading station, hot pressing station and unloading station in sequence as the turntable rotates. This allows the three processes of loading, hot pressing and unloading to be carried out simultaneously on different hot pressing troughs. The time consumed by the pre-assembly process is hidden within the execution cycle of the hot pressing process. This solves the problem of low production efficiency caused by the serial execution of the pre-assembly, hot pressing and unloading processes and the reliance on manual handling for material transfer between stations in the traditional manual mode. It also shortens the production cycle of a single product.

[0019] Fourth, this invention automatically removes the finished parts, which have undergone heat pressing and fixing, from the unloading station and releases them onto the unloading track by setting up an unloading mechanism. This achieves automatic unloading of finished parts, replacing the manual operation of picking up materials one by one, and further reducing labor intensity. Under the coordinated control of the control box, the entire equipment realizes fully automated production from dual-path feeding, positioning pre-assembly, station switching and material transfer, indexing heat pressing and fixing to automatic unloading, reducing reliance on manual labor.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. Example 1

[0024] This application discloses a sheet metal hot pressing assembly device for a shaver plug fixing component, referring to... Figures 1 to 4 This sheet metal hot pressing assembly equipment is used to assemble sheet metal parts 102 onto mounting posts 101a of plastic parts 101 and fix them by hot pressing to form a shaver plug fixing part. The sheet metal hot pressing assembly equipment includes a base plate 100, a feeding mechanism, a station switching mechanism, an indexing hot pressing mechanism, a unloading mechanism 500, and a PLC control box 600.

[0025] Reference Figure 1 - Figure 4 The base plate 100 serves as the supporting foundation for the entire sheet metal hot pressing assembly equipment, and its upper surface is provided with an outer shell 101. In this technical solution, by using the base plate 100 as the basic supporting platform of the equipment, stable support is achieved for each functional mechanism. At the same time, the outer shell 101 provides a protective space for the internal mechanisms of the equipment, avoiding interference from the external environment to the processing process, and providing safety protection for the operators.

[0026] The feeding mechanism is mounted on the base plate 100 and includes a sheet metal part 102 feeding unit 210 for conveying sheet metal parts 102 and a plastic part 101 feeding unit 220 for conveying plastic parts 101. In this technical solution, by integrating the sheet metal part 102 feeding unit 210 and the plastic part 101 feeding unit 220 onto the same base plate 100, a dual-parallel feeding channel for sheet metal parts 102 and plastic parts 101 is formed. This allows the two materials to be supplied synchronously according to a preset rhythm, providing a stable material source for subsequent pre-assembly processes and avoiding production rhythm fluctuations caused by chaotic material handling order or inconsistent speeds during manual handling.

[0027] Reference Figure 5 and Figure 6The workstation switching mechanism is mounted on the base plate 100 and located downstream of the feeding mechanism. This mechanism includes a positioning frame 301 fixedly mounted on the base plate 100, a rotary cylinder 302 mounted on the upper end of the positioning frame 301, and a rotating plate 303 driven by the rotary cylinder 302. The rotating plate 303 has a pre-assembly trough 304, which contains a positioning structure 305 adapted to the shape of the plastic part 101 and the sheet metal part 102. In this technical solution, the positioning frame 301 serves as the supporting body of the workstation switching mechanism, providing a stable mounting base for the rotary cylinder 302. The cooperative arrangement of the rotary cylinder 302 and the rotating plate 303 allows the pre-assembly trough 304 to switch between different angular positions, thereby realizing the workstation switching function of the pre-assembly trough 304 between the assembly station and the conveying station.

[0028] In this embodiment, the pre-assembly groove 304 serves to relative position the sheet metal part 102 and the plastic part 101 and complete the pre-assembly to form a sheet metal assembly. The plastic part 101 feeding unit 220 and the sheet metal part 102 feeding unit 210 first sequentially feed the plastic part 101 and the sheet metal part 102 into the pre-assembly groove 304, at which point the mounting post 101a of the plastic part 101 and the mounting hole 102a of the sheet metal part 102 are assembled. In this technical solution, by providing a positioning structure 305 in the pre-assembly groove 304 that matches the shape of the plastic part 101 and the sheet metal part 102, the plastic part 101 and the sheet metal part 102 can automatically fall to the predetermined assembly position with the help of the positioning structure 305 when sequentially placed, thereby forming a sheet metal assembly. The pre-assembly method replaces the traditional manual assembly process that requires the operator to visually confirm and manually adjust the position, eliminating the assembly misalignment problem caused by human judgment errors.

[0029] Reference Figure 13The positioning structure 305 includes a cavity 309 adapted to the outer contour of the plastic part 101, disposed at the bottom of the pre-assembly groove 304, and a guide surface 311 disposed above the cavity 309. The shape of the cavity 309 matches the outer contour of the plastic part 101. When the plastic part 101 is placed into the pre-assembly groove 304, it automatically falls into a predetermined position at the bottom of the groove under the limiting action of the cavity 309, thereby establishing a stable assembly reference. The guide surface 311 is disposed above the cavity 309 and is used to guide the sheet metal part 102 to fall in along a predetermined direction and align with the mounting post 101a on the plastic part 101. When the sheet metal part 102 is placed on top of the already positioned plastic part 101, it slides in along the predetermined direction under the guidance of the guide surface 311 and automatically aligns with the mounting post 101a. Through the synergistic effect of cavity 309 and guide surface 311, positioning structure 305 realizes the step-by-step positioning of plastic part 101 and sheet metal part 102 in pre-assembly groove 304, avoiding assembly defects caused by incorrect identification direction or misplacement during manual assembly.

[0030] A rotary cylinder 302 drives a rotating plate 303 to switch between at least two angular positions, thereby switching the pre-assembly trough 304 between an assembly station and a conveying station. In this technical solution, when the pre-assembly trough 304 is located at the assembly station, the plastic part 101 feeding unit 220 and the sheet metal part 102 feeding unit 210 sequentially place the plastic part 101 and the sheet metal part 102 into the pre-assembly trough 304 to complete the pre-assembly; after the pre-assembly is completed, the rotary cylinder 302 drives the rotating plate 303 to rotate, thereby switching the pre-assembly trough 304 to the conveying station, so that the subsequent material handling assembly can remove the sheet metal assembly and transfer it to the indexing hot pressing mechanism.

[0031] In a preferred embodiment, the rotating plate 303 is symmetrically provided with two pre-assembly slots 304 along its rotation center. When one pre-assembly slot 304 is located at the assembly station, the other pre-assembly slot 304 is located at the conveying station. This symmetrical dual-slot layout allows pre-assembly operations to be performed in one pre-assembly slot 304 while material transfer operations are being performed in the other, enabling the alternating parallel execution of pre-assembly and material transfer operations, thereby improving the overall operating efficiency of the equipment.

[0032] Reference Figures 9 to 11The indexing hot pressing mechanism is located on one side of the workstation switching mechanism and is used to receive sheet metal assemblies and hot press them to form finished parts. The indexing hot pressing mechanism includes a turntable 401, a motor 402, multiple hot pressing grooves 403, a fixing block 404, rollers 405, a photoelectric sensor 406, and a hot press 407. The indexing hot pressing mechanism uses a hot pressing process to fix and connect the sheet metal parts 102 and plastic parts 101 in the pre-assembled sheet metal assemblies. Compared with the traditional manual hot pressing method, the hot press 407 in the indexing hot pressing mechanism can apply pressure to the mounting column 101a at a preset pressure and temperature, so that the process conditions of each hot pressing operation are consistent, thereby ensuring the forming quality of the flanged structure and the dimensional consistency of the finished parts.

[0033] Reference Figure 12 The unloading mechanism 500 is located on one side of the indexing hot pressing mechanism and is used to automatically unload the finished parts after hot pressing. The unloading mechanism 500 automatically takes the finished parts that have been fixed by hot pressing from the hot pressing groove 403 of the indexing hot pressing mechanism and transfers them to the unloading track 506, realizing the automatic unloading function of finished parts and replacing the manual operation of picking up materials one by one.

[0034] The PLC control box 600 is located on one side of the base plate 100 and is used to control the coordinated operation of the feeding mechanism, the station switching mechanism, the indexing hot pressing mechanism, and the unloading mechanism 500, thereby achieving automated production of shaver plug fixing parts. In this technical solution, the PLC control box 600 has a built-in programmable logic controller and corresponding control program, which coordinates the timing of the actions of each mechanism through preset control logic. By setting up the PLC control box 600, the entire process from material feeding, positioning pre-assembly, station switching, indexing hot pressing fixing to automatic unloading of finished products is automated, eliminating the need for manual intervention and avoiding the problems of unstable cycle time and operational errors associated with manual operation.

[0035] In the overall technical solution of this embodiment, the sheet metal hot pressing assembly equipment automatically feeds sheet metal parts 102 and plastic parts 101 through a feeding mechanism. The positioning structure 305 within the pre-assembly trough 304 automatically positions the two parts to their predetermined assembly positions for accurate pre-assembly. A station switching mechanism enables parallel operation of pre-assembly and material transfer. An indexing hot pressing mechanism uses preset pressure and temperature to induce thermoplastic deformation in the mounting column 101a, forming a flanged structure for stable hot pressing fixation. An unloading mechanism 500 automatically unloads the finished parts. A PLC control box 600 enables fully automated coordinated control of the entire process. This integrated equipment configuration eliminates the reliance on manual assembly and manual hot pressing in the production process of shaver plug fixing parts. It solves the technical problems of low feeding and pre-assembly positioning accuracy, inconsistent manual hot pressing parameters leading to unstable flanged structure forming quality, and low production efficiency caused by the sequential execution of various processes and the inability to operate in parallel, which are common in traditional production methods. Example 2

[0036] Based on Embodiment 1, this embodiment provides a detailed description of the specific structures of the sheet metal part 102 feeding unit 210 and the plastic part 101 feeding unit 220 in the feeding mechanism.

[0037] Reference Figure 7 The sheet metal part 102 feeding unit 210 includes a vibratory plate 211, a separator linear vibratory track 212, a bracket 213, a first horizontal pneumatic slide 214, a second horizontal pneumatic slide 215, a vertical pneumatic slide 216, and a suction cup 218.

[0038] A vibratory feeder 211 is mounted on the base plate 100, and its discharge end is connected to a separator linear vibratory track 212. The vibratory feeder 211 uses a vibratory feeding principle to gradually arrange the batch of randomly fed sheet metal parts 102 into a single direction and orientation through the vibration of the spiral track, and then sequentially output them along the discharge end to the separator linear vibratory track 212. The separator linear vibratory track 212 uses linear vibration to push the sheet metal parts 102 forward one by one, and a separation mechanism is set at the end of the track to allow the sheet metal parts 102 to be separated individually for subsequent pickup. Through the coordinated arrangement of the vibratory feeder 211 and the separator linear vibratory track 212, the sheet metal parts 102 are automatically converted from a disordered, loose state to an ordered, oriented arrangement, replacing the manual picking and orientation adjustment.

[0039] A bracket 213 is mounted on a base plate 100, and a three-axis pneumatic slide assembly is installed on it, forming a pick-and-place execution component 1. The three-axis pneumatic slide assembly includes a first horizontal pneumatic slide 214 mounted on the upper end of the bracket 213 and sliding along a first horizontal direction, a second horizontal pneumatic slide 215 mounted on the sliding end of the first horizontal pneumatic slide 214 and sliding along a second horizontal direction, and a vertical pneumatic slide 216 mounted on the sliding end of the second horizontal pneumatic slide 215 and sliding along a vertical direction, wherein the first horizontal direction and the second horizontal direction are perpendicular to each other.

[0040] The first horizontal pneumatic slide 214 provides a displacement degree of freedom along the first horizontal direction, the second horizontal pneumatic slide 215 provides a displacement degree of freedom along the second horizontal direction, and the vertical pneumatic slide 216 provides a displacement degree of freedom along the vertical direction. The sliding directions of the three pneumatic slides are orthogonal to each other, allowing the actuator mounted at its end to move to any position within the workspace defined by the three-axis travel.

[0041] A suction cup 218 is provided at the end of the vertical pneumatic slide 216. The suction cup 218 picks up and holds the sheet metal part 102 at the end of the separator's vertical vibration track 212 by generating a negative pressure suction force. Through the coordinated operation of the first horizontal pneumatic slide 214, the second horizontal pneumatic slide 215 and the vertical pneumatic slide 216, the suction cup 218 can pick up the sheet metal part 102 from the separator's vertical vibration track 212 and transfer it to the pre-assembly trough 304 for placement.

[0042] The suction cup 218 uses vacuum adsorption to pick up the sheet metal part 102. Compared with mechanical clamping, the adsorption method exerts a more uniform force on the surface of the sheet metal part 102, avoiding the risk of deformation caused by excessive local force during clamping. At the same time, the adsorption method is more adaptable to the shape and size of the sheet metal part 102, and can meet the picking needs of sheet metal parts 102 of different specifications.

[0043] Reference Figure 8 The feeding unit 220 for plastic parts 101 includes a vibratory plate 221, a separator linear vibratory track 222, a support 223, a third horizontal pneumatic slide 224, a vertical pneumatic slide 225, and a chuck 227.

[0044] Vibratory feeder 221 is mounted on base plate 100, and its discharge end is connected to separator linear vibration track 222. The working principle of vibratory feeder 221 is the same as that of vibratory feeder 211; it is used to arrange the batch-loaded plastic parts 101 according to a predetermined direction and orientation, and then transport them to separator linear vibration track 222 for individual separation. By setting up independent vibratory feeder 221 and separator linear vibration track 222, the feeding channels for plastic parts 101 and sheet metal parts 102 are independent of each other, avoiding interference or confusion between parts of different materials and shapes in the same feeding channel.

[0045] The second bracket 223 is mounted on the base plate 100, and a two-axis pneumatic slide assembly is installed on it, forming the second pick-and-place execution component. The two-axis pneumatic slide assembly includes a third horizontal pneumatic slide 224 mounted on the upper end of the second bracket 223 and sliding in the horizontal direction, and a second vertical pneumatic slide 225 mounted on the sliding end of the third horizontal pneumatic slide 224 and sliding in the vertical direction.

[0046] A chuck 227 is provided at the end of the vertical pneumatic slide 225. It is used to clamp the plastic part 101 on the separator's vertical vibration track 222, and under the drive of the third horizontal pneumatic slide 224 and the vertical pneumatic slide 225, the plastic part 101 is placed into the pre-assembly groove 304 before the sheet metal part 102, so that it and the subsequently placed sheet metal part 102 can automatically fall into position in the pre-assembly groove 304 with the positioning structure 305 to form a sheet metal assembly. In this technical solution, the plastic part 101 is placed into the pre-assembly groove 304 before the sheet metal part 102. After the plastic part 101 falls into the predetermined position at the bottom of the groove under the limiting action of the cavity 309, the sheet metal part 102 is placed above the plastic part 101 by the suction cup 218. The sheet metal part 102 falls into the groove along the predetermined direction under the guidance of the guide surface 311 and aligns with the mounting post 101a. The two are relatively positioned in the pre-assembly groove 304 to form a sheet metal assembly. The plastic part 101 is provided with a mounting post 101a for the sheet metal part 102. This application adopts the placement order of plastic part 101 first and sheet metal part 102 later, which ensures that the sheet metal part 102 can be accurately positioned on the mounting post 101a on the plastic part 101 with the help of the positioning structure 305. At the same time, when the plastic part 101 needs to be hot-pressed with two symmetrically arranged sheet metal parts 102, the limiting effect of the cavity 309 can ensure that the bottom of the plastic part 101 is completely engaged in the pre-assembly groove 304, ensuring that the plastic part 101 will not tip over during the sequential assembly of the two sheet metal parts 101, providing a correct and stable assembly foundation for the subsequent hot pressing process.

[0047] In this embodiment, the sheet metal part 102 feeding unit 210 and the plastic part 101 feeding unit 220 operate independently. Through the timing coordination of the PLC control box 600, the alternating feeding and accurate alignment assembly of the sheet metal part 102 and the plastic part 101 are realized. The configuration of the three-axis pneumatic slide assembly in the sheet metal part 102 feeding unit 210 provides the suction cup 218 with flexible spatial movement capability, while the configuration of the two-axis pneumatic slide assembly in the plastic part 101 feeding unit 220 provides the chuck 227 with a simple and efficient pick-and-place path. Example 3

[0048] Based on Embodiment 1 and Embodiment 2, this embodiment provides a detailed description of the specific structure and working process of the material handling assembly, the indexing hot pressing mechanism, and the unloading mechanism 500.

[0049] Reference Figure 5 and Figure 6 The material handling and placement assembly is mounted on the base plate 100, located between the workstation switching mechanism and the indexing hot pressing mechanism. It is used to clamp the pre-assembled sheet metal assemblies in the pre-assembly slot 304 and place them into the hot pressing slot 403 of the indexing hot pressing mechanism. The material handling and placement assembly includes a second positioning frame 306 fixed on the base plate 100, a horizontal pneumatic slide 307 for material handling mounted on the upper end of the second positioning frame 306, a vertical pneumatic slide 308 for material handling mounted on the sliding end of the horizontal pneumatic slide 307, and a second chuck 310 mounted on the end of the vertical pneumatic slide 308.

[0050] In this technical solution, the second positioning frame 306 serves as a support structure for the material transfer and placement assembly. Its position is located between the transfer station of the pre-assembly trough 304 and the indexing hot pressing mechanism, allowing the movement trajectory of the second chuck 310 to cover the material transfer path from the pre-assembly trough 304 to the indexing hot pressing mechanism. The combined configuration of the horizontal pneumatic slide 307 and the vertical pneumatic slide 308 provides the second chuck 310 with degrees of freedom in both the horizontal and vertical directions, enabling it to perform the material transfer action of removing the sheet metal assembly from the pre-assembly trough 304 and placing it at the designated position on the indexing hot pressing mechanism.

[0051] Chuck 310 is used to hold the pre-assembled sheet metal assembly in the pre-assembly slot 304 and, driven by the horizontal pneumatic slide 307 and the vertical pneumatic slide 308, places the sheet metal assembly into the hot press trough 403 located at the loading station. In this technical solution, after the rotary cylinder 302 rotates the pre-assembly slot 304 to the conveying station, chuck 310 descends to the pre-assembly slot 304 under the drive of the vertical pneumatic slide 308 and clamps the sheet metal assembly through the action of the grippers; then the vertical pneumatic slide 308 rises and the horizontal pneumatic slide 307 moves horizontally, transferring the sheet metal assembly to the turntable 401 above the hot press trough 403 located at the loading station; finally, the vertical pneumatic slide 308 descends again, chuck 310 releases the sheet metal assembly, and places it into the hot press trough 403. Through the coordination of this series of actions, the sheet metal assembly is automatically transferred from the workstation switching mechanism to the indexing hot pressing mechanism.

[0052] Reference Figures 9 to 11 The indexing hot pressing mechanism includes a turntable 401, a motor 402, multiple hot pressing grooves 403, a fixing block 404, rollers 405, a photoelectric sensor 406, and a hot press 407.

[0053] A turntable 401 is rotatably mounted on a base plate 100. A motor 402 is mounted on the base plate 100 and is connected to the turntable 401 for driving the turntable 401 to rotate in increments. Multiple hot pressing grooves 403 are evenly distributed circumferentially on the upper surface of the turntable 401, and each hot pressing groove 403 is used to hold a sheet metal assembly.

[0054] In this technical solution, by employing a rotary table 401 in conjunction with multiple hot pressing slots 403 in an indexing layout, multiple sheet metal assemblies can be simultaneously loaded and processed sequentially. The motor 402 drives the rotary table 401 to rotate at preset angles, causing each hot pressing slot 403 to sequentially pass through the loading station, hot pressing station, and unloading station. When a hot pressing slot 403 is at the loading station, the material handling assembly places a sheet metal assembly into it; when the hot pressing slot 403 rotates with the rotary table 401 to the hot pressing station, the hot press 407 performs hot pressing on the sheet metal assembly; when the hot pressing slot 403 continues to rotate to the unloading station, the unloading mechanism 500 removes the finished part. This indexing station layout allows the loading, hot pressing, and unloading processes to be performed simultaneously on different hot pressing slots 403, avoiding the time loss required for sequential waiting in single-station equipment and improving the overall capacity of the equipment. Meanwhile, since two pre-assembly slots 304 are symmetrically provided on the rotating plate 303 of the workstation switching mechanism, while the material transfer component transfers the sheet metal assembly in one pre-assembly slot 304 to the hot press slot 403, the other pre-assembly slot 304 has been switched to the assembly station for a new round of pre-assembly operations, so that the pre-assembly operations and the hot press operations can be carried out in parallel, further shortening the production cycle.

[0055] A fixed block 404 is mounted on the base plate 100, and a roller 405 is rotatably mounted on the upper end of the fixed block 404. The roller 405 rolls in contact with the bottom surface of the turntable 401 to provide auxiliary support for the turntable 401. In this technical solution, the roller 405 provides auxiliary support for the turntable 401, shares the weight of the turntable 401 and the materials it carries, reduces the load on the output shaft of the motor 402, and the rolling contact between the roller 405 and the bottom surface of the turntable 401 reduces the supporting friction, ensuring the smooth rotation of the turntable 401.

[0056] A photoelectric sensor 406 is disposed beside the fixed block 404 to detect the angular position of the turntable 401 and send the detection signal to the PLC control box 600 to control the start and stop of the motor 402. In this technical solution, by setting a detection mark on the turntable 401 that cooperates with the photoelectric sensor 406, the photoelectric sensor 406 can detect the mark signal during the rotation of the turntable 401, thereby determining whether the turntable 401 has rotated to the preset indexing position. The PLC control box 600 controls the start and stop of the motor 402 according to the detection signal of the photoelectric sensor 406, so that the turntable 401 can accurately stop at the angular position corresponding to each station, ensuring the alignment accuracy between the hot press 403 and each station.

[0057] A hot press 407 is mounted on a base plate 100 and located on one side of a turntable 401. This hot press 407 applies a preset pressure and temperature to the sheet metal assembly within the hot press groove 403 at the hot press station, causing the mounting post 101a to undergo thermoplastic deformation to form a flanged structure, thereby securing the sheet metal part 102 to form a finished product. The hot press 407 includes a hot press head and a drive mechanism. The hot press head has a built-in heating element capable of heating the hot press surface to a preset temperature. When the hot press groove 403, carrying the sheet metal assembly, rotates to the hot press station and stops, the drive mechanism of the hot press 407 drives the hot press head downwards, applying a preset pressure and temperature to the mounting post 101a on the plastic part 101 of the sheet metal assembly, causing the mounting post 101a to undergo thermoplastic deformation and form a flanged structure, thereby wrapping and securing the sheet metal part 102 to the plastic part 101.

[0058] The pressure and temperature parameters of the hot press 407 can be preset and adjusted via the PLC control box 600, ensuring consistent process conditions for each hot pressing operation. Compared to manual hot pressing, the preset pressure and temperature applied by the hot press 407 are stable and controllable, avoiding fluctuations in the forming quality of the flanging structure caused by fatigue or inconsistent parameter control during manual operation. Simultaneously, the hot pressing process utilizes the thermoplasticity of the plastic part 101 to induce plastic deformation under heat and pressure, reducing the risk of extrusion damage to the sheet metal part 102 during the pressing process.

[0059] Reference Figure 12 The unloading mechanism 500 includes an unloading rotary cylinder 501, a plate 502, an unloading vertical cylinder 503, and an unloading suction cup 505.

[0060] The material feeding rotary cylinder 501 is fixed on the base plate 100, and the flat plate 502 is fixed on the output end of the material feeding rotary cylinder 501. The material feeding vertical cylinder 503 is fixed on the flat plate 502, and the material feeding suction cup 505 is located on the output end of the material feeding vertical cylinder 503. The material feeding track 506 is located on the base plate 100.

[0061] The unloading rotary cylinder 501 drives the plate 502 to rotate, causing the unloading suction cup 505 to switch between being above the hot pressing groove 403 at the unloading station and above the unloading track 506. When the unloading suction cup 505 needs to pick up the finished part, the unloading rotary cylinder 501 drives the plate 502 to rotate, aligning the unloading suction cup 505 vertically with the hot pressing groove 403 at the unloading station; when the unloading suction cup 505 needs to release the finished part onto the unloading track 506, the unloading rotary cylinder 501 drives the plate 502 to rotate again, moving the unloading suction cup 505 above the unloading track 506.

[0062] The vertical discharge cylinder 503 is used to drive the discharge suction cup 505 to lift and lower to pick up and release the finished part. After the discharge suction cup 505 is aligned with the hot pressing tank 403, the vertical discharge cylinder 503 drives the discharge suction cup 505 to descend above the finished part in the hot pressing tank 403, and the discharge suction cup 505 generates negative pressure to pick up the finished part; then the vertical discharge cylinder 503 drives the discharge suction cup 505 to rise, lifting the finished part from the hot pressing tank 403; the discharge rotation cylinder 501 drives the plate 502 to rotate, moving the finished part to above the discharge track 506; finally, the discharge suction cup 505 releases the negative pressure, and the finished part falls into the discharge track 506, completing the discharge action.

[0063] The unloading track 506 provides a collection and conveying channel for finished parts. In this technical solution, after the finished parts fall into the unloading track 506, they can slide along the track to a designated collection container or subsequent conveying equipment, realizing the orderly collection and transfer of finished parts.

[0064] In the overall operation of this embodiment, the material handling assembly transfers the pre-assembled sheet metal assemblies from the pre-assembly slot 304 to the hot pressing slot 403 of the indexing hot pressing mechanism. The indexing hot pressing mechanism sequentially delivers the sheet metal assemblies to the hot pressing station via the indexing rotation of the turntable 401. The hot press 407 uses preset pressure and temperature to cause thermoplastic deformation of the mounting column 101a, forming a flange structure for hot pressing and fixing. The resulting finished part continues to rotate with the turntable 401 to the unloading station, where it is removed by the unloading mechanism 500 and released onto the unloading track 506. This continuous process is automatically operated under the coordinated control of the PLC control box 600, with the action sequence of each mechanism interconnected, realizing automated hot pressing processing and unloading collection from pre-assembled parts to finished parts. Example 4

[0065] Reference Figure 14 Based on the sheet metal hot pressing assembly equipment described in the above three embodiments, this application also provides a method for processing a shaver plug fixing part, including the following steps: S1. Dual-path feeding: Sheet metal parts 102 are batch-fed into vibratory feeder 211. After being arranged by vibratory feeder 211, the sheet metal parts 102 are conveyed to the separator's linear vibrating track 212 for individual separation. Simultaneously, plastic parts 101 are batch-fed into vibratory feeder 221. After being arranged by vibratory feeder 221, the plastic parts 101 are conveyed to the separator's linear vibrating track 222 for individual separation. In this step, sheet metal parts 102 and plastic parts 101 are conveyed sequentially by their respective feeding mechanisms. The two materials are transformed from disordered bulk materials to ordered arrangement through their respective vibratory feeders and linear vibrating tracks, providing a stable material supply for subsequent automatic pick-and-place operations.

[0066] S2. Positioning and Pre-assembly: First, the plastic part 101 is mechanically clamped and fed into the pre-assembly material tank 304. Then, the sheet metal part 102 is placed on the mounting post 101a of the plastic part 101 by vacuum adsorption. The two parts automatically fall into position with the help of the positioning structure 305 to form a sheet metal assembly. Specifically, the chuck 1 227 moves to the discharge end of the separator direct vibration track 222 under the drive of the third horizontal pneumatic slide 224 and the vertical pneumatic slide 225. After mechanically clamping a plastic part 101, it moves to the top of the pre-assembly material tank 304. After descending, the plastic part 101 is placed in the pre-assembly material tank 304. The plastic part 101 automatically falls into the predetermined position under the limiting action of the cavity 309. Subsequently, driven by the first horizontal pneumatic slide 214, the second horizontal pneumatic slide 215, and the vertical pneumatic slide 216, the suction cup 218 moves to the discharge end of the separator's vertical vibration track 212. It then vacuum-adsorbs a sheet metal part 102 and moves it above the pre-assembly trough 304. After descending, it places the sheet metal part 102 onto the mounting post 101a of the plastic part 101. Guided by the guide surface 311, the sheet metal part 102 falls in a predetermined direction and aligns with the mounting post 101a. The two parts automatically settle into position using the positioning structure 305 to form a sheet metal assembly. In this step, the plastic part 101 is placed in the pre-assembly trough 304 before the sheet metal part 102, providing an assembly reference for the subsequent placement of the sheet metal part 102. The synergistic effect of the cavity 309 of the positioning structure 305 and the guide surface 311 ensures accurate alignment of the sheet metal part 102 and the plastic part 101.

[0067] S3. Station Switching and Material Transfer: Rotary cylinder 302 drives rotary plate 303 to rotate, switching pre-assembly chute 304 from assembly station to transfer station; chuck 2 310 moves to pre-assembly chute 304 under the drive of transfer horizontal pneumatic slide 307 and transfer vertical pneumatic slide 308, picks up sheet metal assembly, moves to turntable 401 above hot pressing groove 403 at loading station, and lowers to place sheet metal assembly in hot pressing groove 403. In this step, sheet metal assembly is transferred from pre-assembly chute 304 to hot pressing groove 403 of indexing hot pressing mechanism through station switching mechanism and material transfer pick-and-place assembly, completing material transfer between processes.

[0068] S4. Indexing Hot Pressing: Motor 402 drives turntable 401 to rotate in an indexing manner, causing the hot pressing groove 403 carrying the sheet metal assembly to reach the hot pressing station and stop. Photoelectric sensor 406 detects the angular position of turntable 401 and sends a position signal to PLC control box 600. Hot press 407 applies preset pressure and temperature to mounting column 101a, causing it to undergo thermoplastic deformation to form a flange structure, thereby locking the sheet metal part 102 to form the finished part. After hot pressing is completed, the hot pressing head rises and resets. In this step, the preset pressure and temperature applied by hot press 407 ensures the consistency of the flange structure forming quality of each product.

[0069] S5. Automatic Unloading: The turntable 401 continues to rotate to the unloading station, where the finished part is removed and released onto the unloading track 506. Specifically, the unloading rotary cylinder 501 drives the plate 502 to rotate, aligning the unloading suction cup 505 vertically with the hot pressing groove 403 located at the unloading station; the unloading vertical cylinder 503 drives the unloading suction cup 505 to descend and pick up the finished part, then rises to lift it from the hot pressing groove 403; the unloading rotary cylinder 501 drives the plate 502 to rotate, transferring the finished part above the unloading track 506; the unloading suction cup 505 releases the finished part, which falls into the unloading track 506, completing the unloading process. In this step, the unloading mechanism 500 automatically completes the removal and release of the finished part, achieving a closed loop in the production process.

[0070] In the execution of steps S3 and S4, steps S1 and S2 are executed synchronously after the other pre-assembly slot 304 or the same pre-assembly slot 304 is reset, allowing the pre-assembly operation to proceed in parallel with the hot pressing operation. Specifically, since two pre-assembly slots 304 are symmetrically arranged on the rotating plate 303, when one pre-assembly slot 304 switches to the conveying station for material transfer and subsequently enters the hot pressing process, the other pre-assembly slot 304 has synchronously switched to the assembly station, and the feeding mechanism simultaneously begins to place the plastic part 101 and the sheet metal part 102 into the pre-assembly slot 304 for a new round of positioning and pre-assembly. Through this parallel operation mode, the time consumed by the pre-assembly process is hidden within the execution cycle of the hot pressing process, shortening the production cycle of a single product and improving overall production efficiency.

[0071] The steps of the above processing method are automatically and cyclically executed according to the preset timing under the control of the PLC control box 600. The actions of each mechanism are coordinated and connected to each other, realizing the fully automated production of shaver plug fixing parts from dual-path material supply, positioning pre-assembly, station switching and material transfer, indexing hot pressing and fixing to automatic unloading.

[0072] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
