Description

Technical Field

[0001] The present application relates to the technical field of injection molding machines, and in particular, to an injection molding machine with a finished product cooling mechanism. Background Art

[0002] With the rise of customized mechanical keyboards, keycaps of various shapes have emerged. Customized keycaps usually have a keycap body for plugging into the keyboard and accessories for plugging or pasting onto the keycap body. The customized expression can be demonstrated not only through various accessories but also by customizing the color of the keycap body, so as to obtain a keyboard with personal characteristics. Whether it is the keycap body or the accessories, injection molding is mainly used as the main production method at present, which can control costs while improving production timeliness and product structure novelty.

[0003] In the related art, before the keycap is completely cured in the mold, the mold needs to be preliminarily cooled to ensure that the keycap has sufficient strength and stability during demolding. After the keycap is demolded, it is naturally cooled and then conveyed to the next process for operations such as coating and assembling accessories.

[0004] In view of the above related art, the natural cooling method does not require additional equipment and has relatively low costs, but the cooling speed is relatively slow, which to a certain extent affects the production efficiency of the keycap. In addition, long-term natural cooling will also cause the keycap surface to absorb moisture or be contaminated. In order not to affect the downstream process of the keycap and to ensure the final use feel of the keycap, further cooling is required after the keycap is demolded to ensure that the keycap reaches the best performance indicators. Summary of the Utility Model

[0005] In order to further cool the demolded keycap, the present application provides an injection molding machine with a finished product cooling mechanism.

[0006] The injection molding machine with a finished product cooling mechanism provided by the present application adopts the following technical solutions:

[0007] An injection molding machine with a finished product cooling mechanism includes an injection molding machine body, a conveying table arranged between the discharge port of the injection molding machine body and the coating station, a manipulator assembly for transferring the demolded keycap from the injection molding machine body to the conveying table, and an air-cooling frame arranged on one side of the conveying table;

[0008] The air-cooling frame includes a mounting frame and air-cooling fans. The mounting frame is arranged along the length direction of the conveying table and is adjacent to the conveying table. A plurality of air-cooling fans are arranged at intervals along the length direction of the mounting frame, and each air-cooling fan is aligned above the conveying table.

[0009] By adopting the above technical solution, the manipulator component transfers the demolded keycaps after injection molding to the conveying table, and then the conveying table transports the keycaps to the coating station. An air-cooling rack is arranged on one side of the conveying table. During the transportation of the keycaps, a plurality of spaced air-cooling fans are used to forcibly air-cool the demolded keycaps, accelerating the cooling speed of the keycaps. Compared with the traditional natural cooling method, the active air-cooling method can significantly shorten the time required for the keycaps to cool, reduce the surface moisture absorption or pollution problems that may occur when the keycaps are exposed to the air for a long time after demolding, help maintain the cleanliness and smoothness of the keycap surface, ensure the processing quality of the keycaps in subsequent processes such as coating and assembling decorative parts, and thus improve the overall production efficiency and the overall quality of the final product.

[0010] Further, the mounting rack includes a support frame body for supporting on the ground and a mounting cover arranged above the support frame body. The outer wall of the mounting cover is fixedly connected to the support frame body. An installation disk for installing and allowing the air-cooling fan to adjust the inclination angle is arranged inside the mounting cover, and the side of the air-cooling fan away from the air outlet is rotatably connected to the installation disk.

[0011] By adopting the above technical solution, the support frame body is firmly supported on the ground, providing a foundation for the air-cooling rack and ensuring the stability of the air-cooling rack during operation. The mounting cover is arranged above the support frame body and fixedly connected to the support frame body. The mounting cover protects the internal air-cooling fan and installation disk from external environmental interference, and at the same time considers the principle of aerodynamics to optimize the air flow path and speed. An installation disk for installing and allowing the air-cooling fan to adjust the inclination angle is arranged inside the mounting cover. The installation disk is the support and adjustment platform for the air-cooling fan, enabling the air-cooling fan to flexibly adjust the air outlet angle according to specific cooling requirements, so as to achieve the best cooling effect.

[0012] Further, the installation disk is provided with an installation groove along the diameter direction. The air-cooling fan is integrally connected with an installation convex portion on the side away from the air outlet for inserting into the installation groove, and a connecting member for the installation convex portion to rotate is penetrated on the installation disk.

[0013] By adopting the above technical solution, the installation convex portion of the air-cooling fan and the installation groove of the installation disk are combined by plugging and the rotational connection effect is achieved through the connecting member, simplifying the installation process. The connecting member allows the installation convex portion to rotate freely within a certain range, thereby realizing the flexible adjustment of the air outlet angle of the air-cooling fan. By adjusting the air outlet angle of the air-cooling fan, it is ensured that the air flow directly and evenly blows towards the keycap surface, improving the cooling efficiency and reducing energy consumption.

[0014] Further, the mounting cover has a back plate for connecting with the support frame body, a top plate for installing the air-cooling fan, and wind baffle plates symmetrically arranged at both ends of the back plate and the top plate.

[0015] By adopting the above technical solution, the backplane, as the connecting part between the installation cover and the support frame, provides a stable support foundation. The top plate provides a platform for the installation of the air-cooling fan. At the same time, the top plate is effectively supported by the backplane. The windshields are symmetrically arranged at both ends of the backplane and the top plate, effectively guiding the flow direction of the air current, so that the air current can blow evenly and concentratedly towards the surface of the keycap, improving the cooling efficiency.

[0016] Further, the support frame is provided with screw legs for fine-tuning the height on the side close to the ground.

[0017] By adopting the above technical solution, the screw legs fine-tune the height of the support frame, which can ensure that the air-cooling fan of the air-cooling frame can accurately align with the conveying path of the keycap, thereby improving the cooling effect and production efficiency. The screw legs have a large contact area with the ground and are connected to the support frame through a threaded structure, which can effectively disperse and resist external vibrations. At the same time, the fine-tuning function of the screw legs can enable the support frame to adapt to different ground materials and different flatness.

[0018] Further, the conveying table has a frame, conveying rollers and a transmission belt. A plurality of rubber seats for placing demolded keycaps are arranged at intervals along the conveying direction on the transmission belt, and a placing groove for placing the demolded keycap is provided on the rubber seat.

[0019] By adopting the above technical solution, the frame supports the conveying rollers and the transmission belt to ensure the stability of the process of conveying the demolded keycap. A plurality of rubber seats are arranged at intervals along the conveying direction on the transmission belt to provide placement positions for the demolded keycaps. The placing grooves on each rubber seat match the shape and size of the keycap, so that the keycap can be stably placed on the rubber seat and is not easy to slide or shift. It helps to maintain the stability of the keycap during the conveying process and avoid interference from air-cooling on the stable placement of the keycap.

[0020] Further, the side of the rubber seat away from the connection with the transmission belt is provided with an inclined placement surface, and the inclined placement surface is inclined upward from the side of the air-cooling frame to the side away from the air-cooling frame.

[0021] By adopting the above technical solution, the inclined placement surface is inclined upward from the side of the air-cooling frame to the side away from the air-cooling frame, so that the demolded keycap can face the air current blown by the air-cooling fan at a more optimized angle during the conveying process, which helps the air current to fully exchange heat with the surface of the keycap, thereby improving the cooling efficiency and accelerating the cooling speed of the keycap.

[0022] Further, the manipulator assembly includes a lifting manipulator for clamping the demolded keycap, a first linear module for driving the lateral movement of the manipulator, and a second linear module for driving the longitudinal movement of the manipulator. A flipping mechanism is provided on the lifting manipulator.

[0023] By adopting the above technical solutions, the lifting manipulator is used to precisely clamp and demold the keycaps and lift them in the vertical direction. The first linear module and the second linear module provide the lifting manipulator with the ability to move horizontally and vertically, enabling the lifting manipulator to have multi-dimensional movement ability, so as to flexibly meet the keycap processing requirements in different positions and directions. The setting of the flipping mechanism enables the lifting manipulator to grab the demolded keycaps at the discharge port of the injection molding machine in the 90° flipping state, and then flip to the horizontal state to place the demolded keycaps on the conveyor table for cooling, ensuring that the keycaps are placed on the rubber seat of the conveyor table in the correct posture, and improving the flexibility of the injection molding machine production line.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By setting an air-cooling rack on one side of the conveyor table and equipping it with multiple air-cooling fans arranged at intervals, forced air cooling of the demolded keycaps is achieved. Compared with the traditional natural cooling method, the active air-cooling method can significantly shorten the time required for keycap cooling and speed up the production process;

[0026] 2. The support frame body realizes height fine-tuning through spiral support feet to ensure that the air-cooling fans of the air-cooling rack can accurately align with the keycap conveying path. The rubber seat on the conveyor table and the placement groove matching the shape and size of the keycaps ensure the stability of the keycaps during the conveying process. The air-cooling fans, mounting plates, and inclined placement surfaces ensure that the air flow directly and evenly blows towards the keycap surface, further improving the cooling efficiency, reducing the surface moisture absorption or pollution problems that may be caused by long-term exposure to the air, and maintaining the cleanliness and smoothness of the keycap surface;

[0027] 3. The manipulator assembly includes a lifting manipulator, a first linear module, a second linear module, and a flipping mechanism. The lifting manipulator, through its own clamping and lifting capabilities, combined with the realization of horizontal and vertical movement of the first linear module and the second linear module, precisely clamps the keycaps and freely moves in a multi-dimensional space to adapt to the keycap processing requirements in different positions and directions. At the same time, the flipping mechanism ensures that the keycaps are placed on the conveyor table in the correct posture, improving the overall flexibility and automation level of the production line.

Detailed implementation manners

[0034] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the following Figures 1-5 in combination with the attached

[0035] and embodiments, the present application will be further described in detail.

[0036] Refer to Figure 1 , the injection molding machine with a finished product cooling mechanism includes an injection molding machine body 1, a conveying table 2, a manipulator assembly 3 and an air-cooling frame 4. The injection molding machine body 1 has a discharge port. The conveying table 2 is arranged between the discharge port of the injection molding machine body 1 and the coating station 5. The air-cooling frame 4 is arranged at an adjacent position on one side of the conveying table 2. The length direction of the air-cooling frame 4 is parallel to the conveying direction of the conveying table 2. The manipulator assembly 3 is arranged between the injection molding machine body 1 and the conveying table 2 to transfer the demolded key caps at the discharge port position of the injection molding machine body 1 to the conveying table 2.

[0037] Refer to Figure 1 and Figure 2, the conveying table 2 includes a frame 21, a conveyor roller 22 and a conveyor belt 23 provided on the frame 21. A plurality of rubber seats 24 are arranged at intervals along the conveying direction on the conveyor belt 23. The rubber seats 24 are integrally connected to the conveyor belt 23. A placement groove 241 for placing the demolded keycaps is formed on the rubber seat 24. In this embodiment, an inclined placement surface 242 is provided on the upper side of the rubber seat 24. The inclined placement surface 242 is inclined upward from one side of the air-cooling frame 4 to the side away from the air-cooling frame 4. When the demolded keycaps are being conveyed, the inclined placement surface 242 can optimize the placement angle of the demolded keycaps, thereby improving the air-cooling effect.

[0038] The manipulator assembly 3 includes a lifting manipulator 31, a first linear module 32 and a second linear module 33. The driving directions of the first linear modules 32 are parallel to each other along the conveying direction of the conveying table 2. The second linear module 33 slides on the first linear module 32 and is perpendicular to the first linear module 32. The lifting manipulator 31 is slidably installed on the lower side of the second linear module 33. Driven by the first linear module 32, the second linear module 33 drives the lifting manipulator 31 to move longitudinally along the conveying direction of the conveying table 2. The second linear module 33 drives the lifting manipulator 31 to move horizontally. The lifting manipulator 31 is provided with a cylinder for providing lifting ability.

[0039] A flipping mechanism 311 is provided on the lifting manipulator 31. In this embodiment, the flipping mechanism 311 is preferably a servo motor. When the lifting manipulator 31 is in the initial state, the end for clamping faces directly downward. When the lifting manipulator 31 is flipped by the flipping mechanism 311, the end of the lifting manipulator 31 for clamping can be flipped by 90° and face the discharge port of the injection molding machine body 1, so as to realize the function of removing the demolded keycaps at the discharge port position of the injection molding machine body 1 and transferring them to the rubber seat 24 on the conveying table 2.

[0040] Refer to Figure 1 and Figure 3 , the air-cooling frame 4 includes a mounting frame 41 and a plurality of air-cooling fans 42. The mounting frame 41 has a support frame body 411 for supporting on the ground and a mounting cover 412 provided above the support frame body 411. The air-cooling fans 42 are installed in the mounting cover 412 and are arranged at intervals along the length direction of the mounting cover 412. A spiral support foot 4111 is threadedly connected to the support frame body 411 on the side close to the ground. When the flatness of the placement surface is low, the height of the support frame body 411 can be finely adjusted by rotating the spiral support foot 4111.

[0041] Combined with Figure 4, the installation cover 412 includes a back plate 4121, a top plate 4122 and a wind deflector 4123 which are integrally connected. The back plate 4121 is perpendicular to the top plate 4122. An extension plate 4112 is integrally connected to the support frame body 411. The extension plate 4112 abuts against the outer wall of the back plate 4121. Pre-drilled holes for bolts to pass through are reserved at corresponding positions on the extension plate 4112 and the back plate 4121. The installation cover 412 is fixedly connected to the support frame body 411 through bolts. An installation disc 413 for installing the air-cooling fan 42 is provided on the inner wall of the top plate 4122. The number of wind deflectors 4123 is two and they are symmetrically arranged at both ends of the top plate 4122 and the back plate 4121. The wind deflectors 4123 are perpendicular to both the back plate 4121 and the top plate 4122.

[0042] In this embodiment, the number of air-cooling fans 42 is preferably four, and the installation discs 413 and the air-cooling fans 42 are arranged in one-to-one correspondence. An installation groove 4131 is formed in the diameter direction on the side of the installation disc 413 away from the inner wall of the top plate 4122. An installation protrusion 421 for inserting into the installation groove 4131 is integrally connected to the side of the air-cooling fan 42 away from the air outlet. A connecting member 414 is passed through the installation disc 413. The connecting member 414 vertically passes through the outer wall of the installation disc 413 and rotatably connects the installation protrusion 421 to the installation disc 413. The passing direction of the connecting member 414 is perpendicular to the opening direction of the installation groove 4131. In this embodiment, the connecting member 414 is preferably a bolt and nut with a relatively simple operation method.

[0043] The implementation principle of an injection molding machine with a finished product cooling mechanism in this application embodiment is as follows: After the injection molding machine body 1 completes injection molding, the demolded keycap is ejected from the discharge port. The lifting manipulator 31 in the manipulator assembly 3 adjusts its posture through the flipping mechanism 311, rotates 90° from the initial state, and clamps the demolded keycap at the discharge port position of the injection molding machine body 1. After the lifting manipulator 31 clamps the demolded keycap, it flips back to the initial state and moves horizontally and longitudinally in the horizontal plane through the coordinated action of the first linear module 32 and the second linear module 33, and transfers the demolded keycap to the rubber seat 24 on the conveying table 2. The transmission belt 23 on the conveying table 2 drives the rubber seat 24 and the demolded keycap placed on the rubber seat 24 to be conveyed towards the coating station 5. An air-cooling frame 4 is provided on one side of the conveying table 2. A plurality of air-cooling fans 42 on the air-cooling frame 4 are arranged at intervals along the conveying direction to forcibly air-cool the demolded keycap during the conveying process. The air-cooling fans 42 are installed and their angles are adjusted through the installation discs 413 in the installation cover 412. The installation groove 4131 is provided on the installation disc 413, and the installation protrusion 421 of the air-cooling fan 42 is rotatably connected through the connecting member 414 (such as a bolt and nut), allowing the air-cooling fan 42 to adjust the air outlet angle within a certain range. The rubber seat 24 on the conveying table 2 is provided with an inclined placement surface 242, so that the demolded keycap can face the air flow blown by the air-cooling fan 42 at an optimized angle during the conveying process, thereby improving the cooling efficiency.

[0044] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
