[0002] In the installation process of plastic parts, pressing is a key step that is frequently used. In the traditional way, pressing is usually done manually or with the help of simple tools.
[0003] However, the traditional manual pressing method has obvious shortcomings. First, from the perspective of work efficiency, the efficiency of manual pressing is relatively low. Furthermore, during the pressing process, it is difficult to ensure that the applied force is evenly distributed on the plastic part. In order to solve the above problems, an automatic pressing device is proposed. Utility Model Content
[0004] The purpose of this application is to provide an automatic pressing device that has the advantages of automatic pressing and solves the problems of low efficiency and uneven force of manual pressing.

By adopting the above technical solution and setting up a cooperative structure of cylinder, push rod, and pressing block, automatic pressing operation of objects can be achieved, improving pressing efficiency and accuracy. Through the combination of rotating rod, rotating disk, and driven gear, main gear, and stepper motor, the rotating disk can be rotated under the drive of the stepper motor, thereby rotating the object placed in the placement groove, facilitating the pressing operation. After pressing the plastic part, air can be blown onto the side of the pressed plastic part through the set air pipe and nozzle, blowing the pressed plastic part out of the placement groove. Then, with the help of the set drainage frame, the plastic frame can be guided to a pre-placed collection box.
[0006] Preferably, a stabilizing ring is fixedly connected to the top of the support frame. The stabilizing ring is located at the bottom of the rotating disk and is coaxial with the rotating disk. Multiple annular grooves are provided on the top of the stabilizing ring and the bottom of the rotating disk. Multiple balls are slidably connected inside the annular grooves. By adopting the above technical solution, and by setting annular grooves and balls, the friction force when the rotating disk rotates can be reduced, making the rotating disk rotate more smoothly and steadily. At the same time, it can also reduce the wear between the rotating disk and the stabilizing ring, and extend the service life of the device.
[0007] Preferably, a second air chamber is provided on the inner side of the placement groove, a first air chamber is provided at the bottom of the second air chamber, and a vent pipe is provided between the first air chamber and the second air chamber.

This ensures that the plastic parts can be stably clamped during the pressing process. The air pressure can be adjusted according to the size and shape of different plastic parts, enabling flexible production.
[0008] Preferably, a first sliding sleeve is fixedly connected inside the first air chamber, a first sliding rod is slidably connected inside the first sliding sleeve, a push plate and a first piston are fixedly connected to both ends of the first sliding rod respectively, the first piston is slidably connected inside the first air chamber, a fixed plate is fixedly connected inside the second air chamber, a second sliding sleeve is fixedly connected inside the fixed plate, a second sliding rod is slidably connected inside the second sliding sleeve, and a clamping plate and a second piston are fixedly connected to both ends of the second sliding rod respectively; By adopting the above technical solution, and by setting components such as a first sliding sleeve, a first sliding rod, a push plate, a first piston, a second sliding sleeve, a second sliding rod, a clamping plate, and a second piston, when the push plate moves, it can drive the first sliding rod to slide within the first sliding sleeve, thereby causing the first piston to move within the first air chamber. Since the first air chamber and the second air chamber are connected by a pipe, the movement of the first piston will change the air pressure within the first air chamber. This air pressure change will be transmitted to the second air chamber, causing the second piston to move accordingly within the second air chamber. The movement of the second piston will then drive the second sliding rod to slide within the second sliding sleeve, ultimately enabling the clamping plate to perform the action of clamping or releasing, thereby achieving the purpose of the automatic pressing device to stably clamp or release objects.
[0009] Preferably, a limiting spring is fitted on the surface of the first slide rod, and the two ends of the limiting spring are respectively fixedly connected to the inner side of the first air chamber and the side of the first piston; By adopting the above technical solution and setting a limiting spring, when the first piston moves in the first air chamber, the limiting spring can provide a certain elastic resistance. When the push plate stops pushing the first piston, the limiting spring can pull the first piston back to the initial position by its own elastic restoring force, thus preparing for the next clamping or releasing action.
[0010] Preferably, an arc-shaped extrusion plate is fixedly connected to the top of the support frame, the arc-shaped extrusion plate is located outside the rotating disk, and a rocker plate is fixedly connected to one side of the arc-shaped extrusion plate; By adopting the above technical solution, and by setting up an arc-shaped extrusion plate and a rocker plate, when the rotating disk rotates to a specific position, the rocker plate can guide the push plate into the gap between the arc-shaped extrusion plate and the rotating disk. At this time, the arc-shaped extrusion plate will exert an extrusion force on the push plate. This extrusion force will be further transmitted to the first slide rod connected to the push plate, causing the first slide rod to slide in the first slide sleeve in a preset direction and force, thereby realizing the precise clamping operation of the entire automatic pressing device at a specific position.
[0011] Preferably, a fixed shell is fixedly connected to the bottom of the support frame, the rotating rod and the stepper motor are both inside the fixed shell, and ventilation holes are provided on the surface of the fixed shell; By adopting the above technical solution, and by setting up a fixed shell to house the rotating rod and the stepper motor, not only can the rotating rod and the stepper motor be protected from external collisions and interference, but the ventilation holes on the surface of the fixed shell can also ensure the circulation of air inside the fixed shell.
[0012] Preferably, handles are fixedly connected to both sides of the top of the support frame, protective pads are provided around the support frame, adjustable support feet are fixedly connected to the four corners of the bottom of the support frame, and a level is connected to the top of the support frame. By adopting the above technical solution, the automatic pressing device can be easily moved and transported by operators by setting a handle. The protective pads around the support frame can reduce the damage to the device caused by collisions during transportation or use. The adjustable support feet and level bubble can be used to adjust the height of the device according to the flatness of the actual use site, ensuring that the device remains horizontal and stable when placed.
[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This automatic pressing device, through the cooperative structure of a cylinder, push rod, and pressing block, enables automatic pressing of objects, improving pressing efficiency and accuracy. The combination of a rotating rod, rotating disk, and driven gears, main gears, and a stepper motor allows the rotating disk to rotate under the drive of the stepper motor, thereby rotating the object placed in the placement groove for convenient pressing. After pressing the plastic part, air is blown onto the side of the pressed plastic part through the provided air pipe and nozzle, causing the pressed plastic part to fall out of the placement groove. Then, with the help of the provided drainage frame, the plastic part can be guided to a pre-placed collection box. 2. This automatic pressing device comprises a first sliding sleeve, a first sliding rod, a push plate, a first piston, a second sliding sleeve, a second sliding rod, a clamping plate, and a second piston. When the push plate moves, it drives the first sliding rod to slide within the first sliding sleeve, thereby causing the first piston to move within the first air chamber. Since the first and second air chambers are connected by a pipe, the movement of the first piston changes the air pressure within the first air chamber. This pressure change is transmitted to the second air chamber, causing the second piston to move accordingly within the second air chamber. The movement of the second piston then drives the second sliding rod to slide within the second sliding sleeve, ultimately causing the clamping plate to clamp or release. This achieves the purpose of the automatic pressing device stably clamping or releasing an object. A limiting spring is also included. When the first piston moves within the first air chamber, the limiting spring provides a certain elastic resistance. When the push plate stops pushing the first piston, the limiting spring can pull the first piston back to its initial position by its own elastic restoring force, preparing for the next clamping or releasing action. By setting an arc-shaped extrusion plate and a rocker, when the rotating disk rotates to a specific position, the rocker can guide the push plate into the gap between the arc-shaped extrusion plate and the rotating disk. At this time, the arc-shaped extrusion plate will exert a squeezing effect on the push plate. This squeezing force will be further transmitted to the first slide rod connected to the push plate, causing the first slide rod to slide in the first sliding sleeve according to the preset direction and force, thereby realizing the precise clamping operation of the entire automatic pressing device at a specific position.

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0017] Example 1: An automatic pressing device, referring to Figure 1 , Figure 2 and Figure 3 The system includes a support frame 1, a cylinder 2 fixedly connected to one side of the top of the support frame 1, a push rod 201 sliding inside the cylinder 2, a pressing block 202 fixedly connected to the bottom end of the push rod 201, a rotating rod 101 tightly nested inside the bottom of the support frame 1, the top end of the rotating rod 101 rotating through the top of the support frame 1 and fixedly connected to a rotating disk 102, a driven gear 104 fixedly connected to the surface of the rotating rod 101, a stepper motor 103 fixedly connected to the bottom of the support frame 1, a main gear 105 fixedly connected to the output end of the stepper motor 103, the driven gear 104 meshing with the main gear 105, and multiple placement grooves 1012 opened on the outer side of the top of the rotating disk 102; A connecting rod 203 is fixedly connected to the side of the cylinder 2, and a fixing sleeve 204 is fixedly connected to the bottom of the connecting rod 203. An air pipe 3 is placed inside the fixing sleeve 204. An air nozzle 303 is fixedly connected to one end of the cylinder 2. A flow guide frame 4 is fixedly connected to the top of the support frame 1. The input end of the flow guide frame 4 is located on the side of the rotating disk 102. By setting the cooperative structure of the cylinder 2, the push rod 201, and the pressing block 202, the automatic pressing operation of the object can be realized, improving the pressing efficiency and accuracy. Through the combination of the rotating rod 101, the rotating disk 102, the driven gear 104, the main gear 105, and the stepper motor 103, the rotating disk 102 can be rotated under the drive of the stepper motor 103, thereby driving the object placed in the placement groove 1012 to rotate, which facilitates the pressing operation. After the plastic part is pressed, air can be blown to the side of the pressed plastic part through the set air pipe 3 and air nozzle 303, which can blow the pressed plastic part out of the placement groove 1012. Then, with the help of the set diversion frame 4, the plastic frame can be diverted into the pre-placed collection box. The top of the support frame 1 is fixedly connected to the stabilizing ring 1030. The stabilizing ring 1030 is located at the bottom of the rotating disk 102 and is coaxial with the rotating disk 102. Multiple annular grooves 1026 are opened on the top of the stabilizing ring 1030 and the bottom of the rotating disk 102. Multiple balls 1027 are slidably connected inside the annular grooves 1026. By setting the annular grooves 1026 and the balls 1027, the friction force when the rotating disk 102 rotates can be reduced, so that the rotating disk 102 rotates more smoothly and steadily. At the same time, the wear between the rotating disk 102 and the stabilizing ring 1030 can be reduced, and the service life of the device can be extended.
[0018] Please see Figure 2 , Figure 4 and Figure 5A second air chamber 1013 is formed on the inner side of the placement groove 1012, and a first air chamber 1014 is formed at the bottom of the second air chamber 1013. A vent pipe 1015 is provided between the first air chamber 1014 and the second air chamber 1013. By setting the second air chamber 1013, the first air chamber 1014 and the vent pipe 1015, air pressure support can be provided for the subsequent clamping action, which can ensure that the plastic part can be stably clamped during the pressing process. The air pressure can be adjusted according to the size and shape of different plastic parts to achieve flexible production. A first sliding sleeve 1016 is fixedly connected inside the first air chamber 1014, and a first sliding rod 1017 is slidably connected inside the first sliding sleeve 1016. Push plates 10 are fixedly connected to both ends of the first sliding rod 1017. 18 and the first piston 1019 are slidably connected in the first air chamber 1014. A fixed plate 1021 is fixedly connected inside the second air chamber 1013. A second sliding sleeve 1022 is fixedly connected inside the fixed plate 1021. A second sliding rod 1023 is slidably connected inside the second sliding sleeve 1022. A clamping plate 1024 and a second piston 1025 are fixedly connected to both ends of the second sliding rod 1023, respectively. By setting components such as the first sliding sleeve 1016, the first sliding rod 1017, the push plate 1018, the first piston 1019, the second sliding sleeve 1022, the second sliding rod 1023, the clamping plate 1024, and the second piston 1025, when the push plate 1018 moves, it can drive the first sliding rod 1017 in the first sliding sleeve 1014. The first piston 1019 moves within the first air chamber 1014 as the first piston 1016 slides within the second air chamber 1013. Since the first air chamber 1014 and the second air chamber 1013 are connected by a pipe, the movement of the first piston 1019 changes the air pressure within the first air chamber 1014. This pressure change is transmitted to the second air chamber 1013, causing the second piston 1025 to move accordingly within the second air chamber 1013. The movement of the second piston 1025 then drives the second sliding rod 1023 to slide within the second sliding sleeve 1022, ultimately causing the clamping plate 1024 to perform clamping or releasing actions. This achieves the purpose of the automatic pressing device to stably clamp or release objects. A limit spring 1020 is fitted on the surface of the first sliding rod 1017, with each end of the limit spring 1020... A limiting spring 1020 is fixedly connected to the inner side of the first air chamber 1014 and the side of the first piston 1019. When the first piston 1019 moves within the first air chamber 1014, the limiting spring 1020 provides elastic resistance. When the push plate 1018 stops pushing the first piston 1019, the limiting spring 1020 can pull the first piston 1019 back to its initial position using its own elastic restoring force, preparing for the next clamping or releasing action. An arc-shaped extrusion plate 1028 is fixedly connected to the top of the support frame 1. The arc-shaped extrusion plate 1028 is located outside the rotating disk 102. A rocker arm 1029 is fixedly connected to one side of the arc-shaped extrusion plate 1028. The arc-shaped extrusion plate 1028 and the rocker arm 1029 are connected together.When the rotating disk 102 rotates to a specific position, the rocker arm 1029 guides the push plate 1018 into the gap between the arc-shaped pressing plate 1028 and the rotating disk 102. At this time, the arc-shaped pressing plate 1028 exerts a pressing force on the push plate 1018. This pressing force is further transmitted to the first slide rod 1017 connected to the push plate 1018, causing the first slide rod 1017 to slide within the first sliding sleeve 1016 according to a preset direction and force, thereby achieving precise clamping operation of the entire automatic pressing device at a specific position.
[0019] Please see Figure 1 and Figure 2 A fixed housing 106 is fixedly connected to the bottom of the support frame 1. The rotating rod 101 and the stepper motor 103 are both located inside the fixed housing 106. Ventilation holes 107 are provided on the surface of the fixed housing 106. By setting the fixed housing 106, the rotating rod 101 and the stepper motor 103 are housed inside, which not only protects the rotating rod 101 and the stepper motor 103 from external collisions and interference, but also ensures air circulation inside the fixed housing 106 through the ventilation holes 107. Handles 1 are fixedly connected to the top of the support frame 1 on both opposite sides. 011, the support frame 1 is equipped with protective pads 109 on all four sides, and adjustable support feet 108 are fixedly connected to the four corners of the bottom of the support frame 1. The top of the support frame 1 is connected to a level bubble 1010. The handle 1011 facilitates the operator to carry and move the automatic pressing device. The protective pads 109 on all four sides of the support frame 1 can reduce the damage to the device caused by collisions during transportation or use. The adjustable support feet 108 and level bubble 1010 can be used to adjust the height of the device according to the flatness of the actual use site to ensure that the device remains horizontal and stable when placed.
[0020] The implementation principle of this application embodiment is as follows: When in use, the operator first determines whether the device is level by observing the level bubble 1010 according to the flatness of the actual site. If it is not level, the height of the device is adjusted by adjusting the support feet 108 to ensure that the device is placed stably. Next, place the plastic part to be pressed into the placement groove 1012 of the rotating disk 102, and then start the stepper motor 103. The main gear 105 at the output end of the stepper motor 103 rotates, driving the driven gear 104 meshing with it to rotate. The driven gear 104 is fixed on the rotating rod 101, thereby causing the rotating rod 101 to rotate, and the rotating disk 102 at the top of the rotating rod 101 also rotates accordingly. When the rotating disk 102 rotates to a specific position, the rocker arm 1029 guides the push plate 1018 into the gap between the arc-shaped extrusion plate 1028 and the rotating disk 102. The arc-shaped extrusion plate 1028 exerts a squeezing effect on the push plate 1018, and the push plate 1018 drives the first slide rod 1017 to slide in the first sliding sleeve 1016. The first piston 1019 at one end of the first slide rod 1017 moves in the first air chamber 1014. Since the first air chamber 1014 and the second air chamber 1013 are connected through the air pipe 1015, the air pressure in the first air chamber 1014 changes and is transmitted to the second air chamber 1013, causing the second piston 1025 in the second air chamber 1013 to move. The second piston 1025 drives the second slide rod 1023 to slide in the second sliding sleeve 1022, and finally the clamping plate 1024 achieves the clamping action, stably clamping the plastic part in the placement groove 1012. Then, start cylinder 2, push rod 201 inside cylinder 2 slides down, and pressing block 202 at the bottom of push rod 201 presses the clamped plastic part. After pressing, the air pipe 3 connected to the side of the cylinder 2 blows air onto the side of the pressed plastic part through the air nozzle 303, blowing the plastic part off from the placement groove 1012. The blown-off plastic part is guided to the pre-placed collection box by the drainage frame 4 fixed on the top of the support frame 1. When the next pressing operation is required, if the push plate 1018 is no longer squeezed by the arc-shaped compression plate 1028, the limit spring 1020 will pull the first piston 1019 back to the initial position by its own elastic restoring force. The first piston 1019 will drive the first slide rod 1017 to slide, thereby releasing the clamping plate 1024. At this time, a new plastic part can be placed again to carry out subsequent operations.
