Description

Technical Field

[0001] This invention relates to the field of door and window fitting assembly equipment technology, and more specifically, to an integrated equipment for the manufacture and automatic assembly of door and window corner seat springs. Background Technology

[0002] In existing door and window fitting production, the corner bracket and spring are assembled by riveting. In this process, one end of the corner bracket is equipped with an anchor point for riveting with the spring, while the other end is riveted with a rivet for subsequent installation of the entire assembly onto the door or window. The two ends of the spring are respectively equipped with holes for riveting and reserved holes. The characteristic of these reserved holes in use is that when multiple springs are riveted and fixed on the corner bracket and bent into a 90-degree angle, the center of their reserved holes must be precisely aligned, and the free ends of all springs must remain flush to meet the precise alignment requirements during the door and window installation process.

[0003] Traditionally, this processing and assembly process is usually completed manually by workers, which is not only inefficient but also results in inconsistent processing accuracy. This production mode is both time-consuming and labor-intensive, and there is an urgent need for technological improvements to enhance assembly efficiency and product quality. Therefore, proposing an automated corner seat spring assembly device to solve the current technical challenges faced by the industry has become the direction of efforts for those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and provide an integrated equipment for the production and automatic assembly of door and window corner seat springs with high production efficiency and high processing precision.

[0005] To address the aforementioned problems, this invention provides an integrated device for the fabrication and automatic assembly of corner bracket springs for doors and windows. The device includes a workbench and a turntable mounted on the workbench and rotating quantitatively around a fixed axis. Several workstations are distributed along the circumference of the workbench at intervals corresponding to the turntable's step length. A fixture for placing corner brackets is provided on the turntable at each workstation. Each workstation on the workbench sequentially includes a first riveting mechanism, a spring-feeding mechanism, and a second riveting mechanism. The first riveting mechanism is used to rivet and fix the corner brackets on the fixture. The spring-feeding mechanism is used to sequentially place multiple springs on the anchor points of the corner brackets on the fixture. The second riveting mechanism is used to rivet and fix the corner brackets and springs on the fixture. A spring-feeding mechanism and a spring-feeding supply mechanism are provided on one side of the spring-feeding mechanism. The multi-strip material supply mechanism has a base fixed on the worktable for placing multiple strips side by side on its top. The spring piece making mechanism includes a pulling component, a perforating component, and a cutting component mounted on the base. The pulling component is mounted on the base and can move back and forth, and is used to pull out multiple strips from the material supply mechanism. The perforating component is located between the pulling component and the material supply mechanism and is used to make rivet holes and reserved holes with different hole spacings on each strip. The cutting component is located between the pulling component and the perforating component and is used to cut the strips according to the hole spacing on each strip to form spring pieces of different lengths. The spring piece upper mechanism can move back and forth between the base and the fixture and is used to pick up multiple spring pieces from the base and stack them in order of length on the anchor point of the corner seat on the fixture.

[0006] Compared with existing technologies, the advantages of this invention are as follows: This invention employs an automated spring sheet manufacturing mechanism to precisely control the cutting length of each spring sheet and the spacing between the pre-drilled holes and riveting holes. This allows multiple spring sheets to have different lengths and corresponding hole spacings. These parameters are preset on the cutting and perforating components after precise calculations. Through this precise setting, not only is the length and hole spacing of each spring sheet strictly consistent with the design values ​​during the manufacturing process, but it also ensures that when the entire assembly is installed on doors and windows, the center of the pre-drilled holes of the multiple spring sheets are precisely aligned and the free ends of the spring sheets are perfectly aligned. Spring sheets manufactured using the spring sheet manufacturing mechanism of this invention, in a straight state... The centers of the pre-drilled holes may be misaligned and the free ends may not be aligned. When the spring is bent at 90 degrees, it can meet the requirements of precise alignment of the pre-drilled holes and alignment of the free ends during door and window installation. At the same time, the intelligent operation of the upper spring mechanism can accurately pick up and sequentially stack multiple springs of different lengths onto the anchor points of the corner seat for riveting and fixing. This process significantly improves the riveting accuracy and product consistency, reduces the complexity and error rate of manual operation, and ultimately greatly improves the efficiency and product quality of the entire production process. These advantages make this invention demonstrate higher industrial application value than existing technologies in industries with high precision assembly requirements, especially in door and window manufacturing.

[0007] Specifically, the spring-loaded mechanism includes a robotic arm capable of horizontal swinging and vertical lifting, and multiple gripper components with automatic opening and closing functions. A first support is fixed to the top of the base, the robotic arm is mounted on the first support and can swing horizontally between the base and the clamp, and the gripper components are mounted on the robotic arm and move synchronously with the robotic arm in the horizontal and vertical directions. With this structure, the robotic arm of the spring-loaded mechanism can move precisely in the horizontal and vertical directions, cooperating with the multiple gripper components to achieve stable gripping and precise placement of the spring.

[0008] Specifically, the material feeding component includes multiple pressure blocks corresponding to multiple material strips and multiple rodless cylinders for driving the pressure blocks forward. The rodless cylinders are arranged side-by-side on the machine base, and each cylinder's output end has a mounting base. The pressure blocks are positioned corresponding to their respective mounting bases and can move up and down on them. Each mounting base has a drive component for driving its corresponding pressure block up and down. With this structure, the rodless cylinders provide a stable and precise linear driving force, ensuring accurate and continuous forward and backward movement of the pressure blocks. Driven by the drive components, the pressure blocks press down on or release the front end of the material strip. When the pressure block presses down on the front end of the material strip, the material strip can be pulled out of the material supply mechanism under the drive of the rodless cylinders.

[0009] Specifically, the piercing component includes multiple sets of riveting hole piercing machines and pre-drilled hole piercing machines. A second support is mounted on the machine base. These machines are arranged side-by-side on the second support, corresponding to multiple strips of material. Each set of machines is spaced apart, and the hole spacing between them varies. This layout not only improves piercing accuracy but also increases operational efficiency, enabling simultaneous piercing of multiple strips. Furthermore, due to its adjustable hole spacing design, the piercing system maintains hole position accuracy and product quality even at high speeds, reducing production errors while enhancing equipment adaptability and operational stability. In summary, this piercing system design meets the demands of high-precision and large-scale production, effectively improving industrial production efficiency and product quality, and bringing significant application advantages.

[0010] Specifically, the cutting component includes a liftable press and multiple matching cutting sections. A third support is mounted on the machine base, and the press is lifted and positioned on the third support. The multiple cutting sections are arranged side-by-side and spaced back-to-back at the bottom of the press. By applying this structure, the cutting component design, through the unique combination of the liftable press and its multiple cutting sections at the bottom, achieves simultaneous and precise cutting of multiple strips. The side-by-side and spaced-back distribution of the multiple cutting sections ensures that the cutting action precisely corresponds to the different hole spacings on each strip, thereby ensuring that the cut spring pieces have varying lengths to meet design requirements. This design not only improves the efficiency of the cutting operation but also ensures the accuracy of the manufacturing process and the consistency of the product, providing a solid technical guarantee for the production of high-quality spring pieces.

[0011] Specifically, the material supply mechanism includes a feeding rack, multiple reels corresponding to various material strips, and multiple material handling guides matching the reels. The feeding rack is located on one side of the spring-making mechanism. Each reel rotates around its axis on the feeding rack to supply material strips. The material handling guides correspond to the reels and are used to organize and guide the material strips to the spring-making mechanism. With this structure, the feeding rack design allows multiple reels to supply different material strips in an orderly manner, ensuring the continuity and stability of the supply. While each reel rotates around its axis to supply material strips, the matching material handling guides organize and guide the strips, effectively preventing tangling and cross-linking during transport and ensuring that the material strips are fed smoothly and orderly into the spring-making mechanism.

[0012] As an improvement, a corner seat flipping mechanism is also included for flipping the corner seat located on the fixture. The corner seat flipping mechanism is located between the first riveting mechanism and the upper spring mechanism. The corner seat flipping mechanism includes a clamping component for clamping the corner seat from the fixture, a flipping component for controlling the flipping of the corner seat, a lifting component for controlling the vertical displacement of the clamping component, and a translating component for controlling the horizontal displacement of the clamping component. The translating component is horizontally slidably disposed on the worktable, the lifting component is disposed at the output end of the translating component, the flipping component is disposed at the output end of the lifting component, and the clamping component is disposed at the output end of the flipping component. After applying this structure, the corner seat flipping mechanism can achieve efficient and precise flipping operation of the corner seat, adding flexibility to the production process. Especially when the anchor point and rivet on the corner seat are not on the same side, by clamping the clamping component and flipping the flipping component, the corner seat can be quickly flipped and guided after the first riveting mechanism rivets and fixes the rivet on one side of it, so that the side with the anchor point is facing upwards. This makes it convenient to use the upper spring plate mechanism to sequentially place multiple spring plates on the anchor point of the corner seat, and finally rivet and fix it by the second riveting mechanism.

[0013] As an improvement, the fixtures are detachably mounted on the turntable. This detachable design makes the workstations on the turntable more flexible and modular, facilitating quick fixture changes to meet the production needs of different types of corner seats.

[0014] As an improvement, an offline transfer mechanism is also included for picking up the assemblies of the corner brackets and springs, which have been riveted and fixed by the second riveting mechanism, from the fixture and transferring them to another location. The offline transfer mechanism is located on the workbench and corresponds to one of the multiple workstations. The offline transfer mechanism includes a picking robotic arm on the workbench and a conveying device extending under the picking robotic arm. The picking robotic arm can reciprocate between the conveying device and the turntable, and is used to pick up the assemblies from the fixture and place them onto the conveying device. With this mechanism, the picking robotic arm replaces manual labor in picking up the assemblies riveted and fixed by the second riveting mechanism from the fixture on the turntable, while the conveying device transports the assemblies to another location for storage. Compared to manually assembling assemblies from the fixture on the turntable, this structure has higher picking efficiency and also avoids burns to the hands caused by the localized high temperatures generated during the operation of the second riveting mechanism.

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Example 1: As Figures 1 to 4 As shown, in this embodiment, the integrated equipment for manufacturing and automatically assembling corner bracket springs for doors and windows includes a workbench 1 and a turntable 2 mounted on the workbench 1 and rotating quantitatively around a fixed axis. Several workstations are distributed along the circumference of the workbench 1 at intervals according to the step length of the turntable 2. A fixture 20 for placing corner brackets is provided on the turntable 2 for each workstation. Each workstation on the workbench 1 is sequentially equipped with a first riveting mechanism 3, a spring-loaded mechanism 4, and a second riveting mechanism 5. The first riveting mechanism 3 is used to rivet and fix the rivets of the corner brackets on the fixture 20. The spring-loaded mechanism 4 is used to sequentially place multiple springs on the anchor points of the corner brackets on the fixture 20. The second riveting mechanism 5 is used to rivet and fix the corner brackets and springs on the fixture 20. A spring-loaded mechanism 6 and a material strip for supplying multiple material strips to the spring-loaded mechanism 6 are provided on one side of the spring-loaded mechanism 4. The supply mechanism 7 and the workbench 1 are fixed with a base 8 for placing multiple strips of material side by side on its top. The spring piece making mechanism 6 includes a pulling component 61, a perforating component 62 and a cutting component 63 on the base 8. The pulling component 61 can move back and forth on the base 8 and is used to pull out multiple strips of material from the strip supply mechanism 7. The perforating component 62 is located between the pulling component 61 and the strip supply mechanism 7 and is used to make rivet holes and reserved holes with different hole spacings on each strip. The cutting component 63 is located between the pulling component 61 and the perforating component 62 and is used to cut the strips of material into spring pieces of different lengths according to the hole spacing on each strip. The upper spring piece mechanism 4 can move back and forth between the base 8 and the clamp 20 and is used to pick up multiple spring pieces from the base 8 and stack them in order of length on the anchor point of the corner seat on the clamp 20.

[0019] Compared with the prior art, the advantages of this invention are as follows: This invention employs an automated spring sheet manufacturing mechanism 6 to precisely control the cutting length of each spring sheet and the spacing between the reserved holes and riveting holes, so that multiple spring sheets each have different lengths and corresponding hole spacings. These parameters are preset on the cutting component 63 and the perforating component 62 after precise calculation. Through this precise setting, not only is the length and hole spacing of each spring sheet strictly consistent with the design value during the processing and manufacturing process, but it also ensures that when the entire assembly is installed and used on doors and windows, the center of the reserved holes of multiple spring sheets are precisely aligned and the free ends of the spring sheets are perfectly aligned. The spring sheets processed using the spring sheet manufacturing mechanism 6 of this invention are flat. In the current state, the centers of the reserved holes will be misaligned and the free ends will not be flush. When the spring is bent at 90 degrees, it can meet the requirements of precise alignment of the reserved holes and flush free ends in the installation of doors and windows. At the same time, the intelligent operation of the upper spring mechanism 4 can accurately pick up and sequentially stack multiple springs of different lengths onto the anchor point of the corner seat for riveting and fixing. This process significantly improves the riveting accuracy and product consistency, reduces the complexity and error rate of manual operation, and ultimately greatly improves the efficiency and product quality of the entire production process. These advantages make this invention demonstrate higher industrial application value than existing technologies in industries with high precision assembly requirements, especially in door and window manufacturing.

[0020] like Figure 3 , Figure 5 and Figure 6 As shown, the upper spring mechanism 4 includes a robotic arm 41 capable of horizontal swinging and vertical lifting, and multiple gripper components 42 with automatic opening and closing functions. A first support 81 is fixed to the top of the base 8. The robotic arm 41 is mounted on the first support 81 and can swing horizontally between the base 8 and the clamp 20. The gripper components 42 are mounted on the robotic arm 41 and move synchronously with the robotic arm 41 in the horizontal and vertical directions. The gripper components 42 typically consist of a finger cylinder and a pair of gripping blocks corresponding to a pair of grippers on the finger cylinder. With this structure, the robotic arm 41 of the upper spring mechanism 4 can move precisely in the horizontal and vertical directions, cooperating with the multiple gripper components 42 to achieve stable gripping and precise placement of the spring.

[0021] like Figure 3 , Figure 5 and Figure 6As shown, the feeding component 61 includes multiple pressure blocks 611 corresponding to multiple material strips and multiple rodless cylinders 612 for driving the pressure blocks 611 forward. The multiple rodless cylinders 612 are arranged side by side on the machine base 8, and each rodless cylinder 612 has a mounting base 613 at its output end. The pressure blocks 611 are set on the mounting bases 613 and can move up and down on their respective mounting bases 613. Each mounting base 613 is provided with a driving component 614 for driving the pressure block 611 to move up and down. The driving component 614 can be a cylinder or a lead screw motor. With this structure, the rodless cylinders 612 provide a stable and precise linear driving force, ensuring that the pressure blocks 611 move accurately and continuously back and forth. Under the drive of the driving component 614, the pressure blocks 611 press or release the front end of the material strip. When the pressure block 611 presses the front end of the material strip, the material strip can be pulled out from the material strip supply mechanism 7 under the drive of the rodless cylinders 612.

[0022] like Figure 3 , Figure 5 and Figure 6 As shown, the piercing component 62 includes multiple sets of riveting hole piercing machines 621 and pre-drilled hole piercing machines 622. A second support 82 is provided on the machine base 8. The multiple sets of riveting hole piercing machines 621 and pre-drilled hole piercing machines 622 are arranged side-by-side on the second support 82, corresponding to multiple strips of material. Each set of riveting hole piercing machines 621 and pre-drilled hole piercing machines 622 is spaced apart, and the hole spacing between each set of riveting hole piercing machines 621 and pre-drilled hole piercing machines 622 is different. This layout not only improves the accuracy of piercing but also increases operational efficiency, enabling simultaneous piercing of multiple strips of material. Furthermore, due to its adjustable hole spacing design, this piercing system can maintain hole position accuracy and product quality even during high-speed operation, reducing production errors while improving equipment adaptability and operational stability. In summary, this piercing system design adapts to the needs of high-precision and large-scale production, effectively improving industrial production efficiency and product quality, and bringing significant application advantages.

[0023] like Figure 3 , Figure 5 and Figure 6As shown, the cutting component 63 includes a liftable press 631 and multiple cutting sections 632. A third support 83 is provided on the base 8, and the press 631 is liftably mounted on the third support 83. The multiple cutting sections 632 are arranged side-by-side and spaced back-to-back at the bottom of the press 631. By applying this structure, the design of the cutting component 63, through the unique combination of the liftable press 631 and the multiple cutting sections 632 at its bottom, achieves simultaneous and precise cutting of multiple strips of material. The side-by-side and spaced-back arrangement of the multiple cutting sections 632 ensures that the cutting action precisely corresponds to the different hole spacings on each strip, thereby ensuring that the cut spring pieces have varying lengths to meet design requirements. This design not only improves the efficiency of the cutting operation but also ensures the accuracy of the manufacturing process and the consistency of the product, providing a solid technical guarantee for the production of high-quality spring pieces.

[0024] like Figure 3 and Figure 7 As shown, the material supply mechanism 7 includes a feeding frame 71, multiple reels 72 corresponding to multiple material strips, and multiple material handling guides 73 matching the reels 72. The feeding frame 71 is located on one side of the spring sheet making mechanism 6. The multiple reels 72 are each rotatably mounted on the feeding frame 71 around an axis to supply material strips. The material handling guides 73 correspond to the reels 72 and are used to sort and guide the material strips to the spring sheet making mechanism 6. With this structure, the design of the feeding frame 71 allows the multiple reels 72 to supply different material strips in an orderly manner, ensuring the continuity and stability of the supply. While each reel 72 rotates around an axis to supply material strips, the matching material handling guides 73 sort and guide the material strips, effectively preventing the material strips from tangling and crossing during the conveying process, and ensuring that the material strips can be fed into the spring sheet making mechanism 6 in a flat and orderly manner.

[0025] In this invention, both the first riveting mechanism 3 and the second riveting mechanism 5 include a support frame on the workbench 1 and a riveting machine on the support frame. The riveting machine at the first riveting mechanism 3 is used to rivet and fix the base and the rivets on the base to form an assembly. The riveting machine at the second riveting mechanism 5 is used to rivet and fix the base and multiple spring pieces placed on the base in sequence.

[0026] like Figure 2 and Figure 3As shown, it also includes an off-line transfer mechanism 10 for picking up the assembly of the corner seat and spring piece after being riveted and fixed by the second riveting mechanism 5 from the fixture 20 and transferring it to another location. The off-line transfer mechanism 10 is located on the workbench 1 and corresponds to one of the multiple workstations. The off-line transfer mechanism 10 includes a picking robot arm 101 located on the workbench 1 and a conveying device 102 with one end extending under the picking robot arm 101. The picking robot arm 101 can reciprocate between the conveying device 102 and the turntable 2 and is used to pick up the assembly from the fixture 20 and place it on the conveying device 102. After applying this mechanism, the robotic arm 101 replaces manual labor in picking up the assembly fixed by the second riveting mechanism 5 from the clamp 20 of the turntable 2. At the same time, the assembly is transported to another storage location by the conveying device 102. Compared with manual assembly from the clamp 20 of the turntable 2, this structure has higher picking efficiency and can also avoid local high temperature burns to the hands caused by the assembly during the operation of the second riveting mechanism 5.

[0027] The spring clips riveted to the base in this invention are typically four pieces. The assembly steps for the base and spring clips using this invention are as follows: Step 1: An operator manually places the base onto the clamp 20 on the turntable 2, and the turntable 2 rotates intermittently to enter the working position of the first riveting mechanism 3; Step 2: At the working station of the first riveting mechanism 3, the base is riveted and fixed to the rivets on the base by the riveting machine at the first riveting mechanism 3, and then rotated into the working station of the upper spring mechanism 4 by the turntable 2 at intervals. Step 3: At the working station of the upper spring sheet mechanism 4, several spring sheets with precisely calculated lengths and hole spacings are prepared by the spring sheet making mechanism 6. These spring sheets each have different lengths and corresponding hole spacings. Then, the upper spring sheet mechanism 4 picks up multiple spring sheets from the machine base 8 and stacks them on the anchor points of the base in length order. Next, the turntable 2 rotates at intervals to the working station of the second riveting mechanism 5. The working steps of the spring sheet making mechanism 6 in preparing spring sheets are as follows: First, multiple strips of material are pulled out from the strip supply mechanism 7 to different lengths by the pulling component 61. Then, holes are punched on each strip by the perforating component 62 corresponding to each strip. Riveting holes and reserved holes are punched on each strip, and the hole spacing between the riveting holes and reserved holes on each strip is different. Finally, the cutting component 63 is used to cut the strip into spring sheets of different lengths according to the hole spacing on each strip.

[0028] Step 4: At the working station of the second riveting mechanism 5, the base and multiple spring pieces placed on the base in sequence are riveted and fixed by the riveting machine at the second riveting mechanism 5, and then rotated into the working station of the offline transfer mechanism 10 by the turntable 2 at intervals. Step 5: At the work station of the off-line transfer mechanism 10, the picking robot arm 101 moves back and forth between the conveying device 102 and the turntable 2. The picking robot arm 101 picks up the assembly that has been riveted and fixed by the second riveting mechanism 5 from the clamp 20 of the turntable 2 and puts it on the conveying device 102 to be transferred to another place for storage or use.

[0029] Example 2: This example is based on Example 1, but differs from Example 1 in the following ways: like Figures 8 to 10 As shown, it also includes a corner seat flipping mechanism 9 for flipping the corner seat located on the clamp 20. The corner seat flipping mechanism 9 is located between the first riveting mechanism 3 and the upper spring mechanism 4. The corner seat flipping mechanism 9 includes a clamping component 91 for clamping the corner seat from the clamp 20, a flipping component 92 for controlling the flipping of the corner seat, a lifting component 93 for controlling the vertical displacement of the clamping component 91, and a translation component 94 for controlling the horizontal displacement of the clamping component 91. The translation component 94 is horizontally slidably disposed on the worktable 1. The lifting component 93 is disposed at the output end of the translation component 94, the flipping component 92 is disposed at the output end of the lifting component 93, and the clamping component 91 is disposed at the output end of the flipping component 92. Specifically, the gripping component 91 consists of a finger cylinder and a pair of gripping blocks corresponding to a pair of grippers on the finger cylinder; the flipping component 92 is a flipping cylinder, with the body of the finger cylinder mounted on the rotating output end of the flipping cylinder via a fixing block; the lifting component 93 is a lifting cylinder with the piston rod positioned upwards or downwards, with the body of the flipping cylinder mounted on the piston rod of the lifting cylinder via a fixing block; and the translation component 94 is a drive cylinder with the piston rod placed horizontally, with the body of the lifting cylinder mounted on the piston rod of the drive cylinder via a fixing block. After applying this structure, the corner seat flipping mechanism 9 can achieve efficient and precise flipping operation of the corner seat, adding flexibility to the production process. Especially when the anchor point and rivet on the corner seat are not on the same side, by clamping the clamping part 91 and flipping the flipping part 92, the corner seat can be quickly flipped and guided after the first riveting mechanism 3 rivets the rivet on one side of it, so that the side with the anchor point faces upward. This makes it easier to use the upper spring plate mechanism 4 to sequentially place multiple spring plates on the anchor point of the corner seat, and finally rivet it by the second riveting mechanism 5.

[0030] Furthermore, the fixture 20 is detachably mounted on the turntable 2. The fixture 20 and the turntable 2 can be connected by snap-fit, threaded connection, or other methods to achieve a detachable connection. With this structure, the detachable design of the fixture 20 makes the workstation on the turntable 2 flexible and modular, facilitating the quick replacement of the fixture 20 according to the production needs of different types of corner seats.

[0031] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
