Description

Technical Field

[0001] This invention relates to the field of umbrella rib processing technology, specifically to a reverse umbrella rib processing and fixing device. Background Technology

[0002] Reverse ribs refer to umbrella ribs that fold upwards when the umbrella is closed.

[0003] In the current technology, the riveting and assembly technology of umbrella ribs is still relatively primitive, mainly relying on manual operation. The umbrella rib segments are spliced ​​by hand and then fixed between the spliced ​​umbrella rib segments with rivets. For ease of use, the higher-end umbrellas generally have a thrust spring between the first connecting rod and the second connecting rod. When the button is pressed, the umbrella opens automatically under the thrust of the thrust spring. However, the thrust spring and related connecting blocks generally need to be installed manually.

[0004] In the prior art, the umbrella rib fixing device used in the sunshade umbrella production line has the following defects:

[0005] 1. When installing the umbrella ribs, the ribs cannot be rotated to make them rotate, which consumes a lot of manual labor.

[0006] 2. There is no angle rotation adjustment setting, which makes it inconvenient to adjust the assembly angle of the umbrella ribs. Summary of the Invention

[0007] The purpose of this invention is to provide a reverse umbrella rib processing and fixing device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a reverse umbrella rib processing and fixing device, comprising a worktable and a controller fixed to the top of the worktable. The worktable has an insertion hole in the middle, and the umbrella handle is movably inserted into the insertion hole. A U-shaped plate is fixed to the bottom of the worktable, and a rotating shaft is rotatably connected to the top of the U-shaped plate. A rotating disk is fixed to the top of the rotating shaft, and a clamping component for clamping the umbrella handle is provided on the top of the rotating disk. A lifting component is provided on one side of the umbrella handle, and the lifting component drives the pull ring to move up and down along the umbrella handle body. A support component is provided on the outside of the lifting component, and the support component supports the first connecting rod, thereby facilitating the connection between the first connecting rod and the second connecting rod.

[0009] Furthermore, the bottom rod of the rotating shaft extends into a U-shaped plate, and a rotating assembly is provided at its end.

[0010] Furthermore, the rotating assembly includes two vertical plates, a worm gear, a worm, and a motor. The worm is tactilely connected between the two vertical plates, the motor is fixed to the side of the vertical plate, and its output end is fixed to the end of the worm. The worm gear is fixed to the bottom end of the rotating shaft and meshes with the worm.

[0011] Furthermore, the clamping assembly includes a double-headed electric telescopic rod and two movable plates. The two movable plates are respectively fixed to the ends of the telescopic ends of the double-headed electric telescopic rod. The top of the movable plates is rotatably connected to a clamping roller through a first connecting shaft. The clamping rollers are symmetrically arranged on both sides of the umbrella handle. When the two movable plates move towards each other, the umbrella handle is clamped by the clamping rollers.

[0012] Furthermore, the clamping roller is a rubber roller with anti-slip texture on its surface.

[0013] Furthermore, the lifting assembly includes a rectangular groove formed on the top of the worktable, a fixed shaft fixed between the walls of the rectangular groove, a slider movably connected to the shaft of the fixed shaft, a first spring fixed between the slider and the wall of the rectangular groove, a single-headed electric telescopic rod fixed to the top of the slider, a top block fixed to the end of the telescopic end of the single-headed electric telescopic rod, an arc-shaped groove formed on the top block relative to the pull ring side, straight grooves formed at the top and bottom of the arc-shaped groove, a rotating roller tumblingly connected to the straight groove through a second connecting shaft, the top surface of the rotating roller protruding from the wall of the arc-shaped groove, and a handle fixed to the outside of the top block.

[0014] Furthermore, the support assembly includes two blocks, one of which is rolled with a stud on its inner side. The stud is movably inserted into the other block. A fastening nut is screwed onto the stud's shaft, and a support portion is fixed on the stud's shaft to support the first connecting rod.

[0015] Furthermore, the support includes a socket rod and a telescopic shaft. The telescopic shaft is movably connected to the socket rod. A second spring is fixed between the telescopic shaft and the bottom wall of the socket rod slot. A U-shaped block is fixed to the end of the telescopic shaft. A support roller is rolled between the U-shaped blocks through a third connecting shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This reverse umbrella rib processing and fixing device is equipped with a lifting component, a clamping component, and a rotating component. When splicing and installing umbrella rib sections, the clamping component clamps and fixes the umbrella handle, and also limits the position of the pull ring on the umbrella handle. Then, the rotating component drives the umbrella handle to rotate. The worker first splices and installs the first and second connecting rods, and then splices the remaining connecting rods in sequence. In this way, there is no need for manual installation around the umbrella handle, thereby reducing labor and improving work efficiency.

[0018] Meanwhile, a support assembly is provided to support the first connecting rod. The assembly angle of the first connecting rod can be adjusted according to the worker's height or work habits, thereby further improving the practicality of the device.

[0019] After the umbrella rib section is installed, the lifting assembly pushes the pull ring to move vertically along the umbrella handle, thereby adjusting the angle between the first connecting rod and the second connecting rod. This facilitates the installation of the tension spring and related connecting parts of the automatic umbrella, further improving work efficiency.

[0020] Furthermore, by using the lifting assembly to move the pull ring vertically up and down along the umbrella handle, the process of closing and opening the umbrella can be simulated. This allows for testing the performance of the reverse umbrella ribs after installation, thus promptly identifying any installation problems, reducing defective products from entering the market, and improving product quality and user experience.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention is applied to the fixing of reverse umbrella ribs, thereby facilitating the installation and fixing between reverse umbrella rib segments and the installation of corresponding auxiliary components.

[0030] like Figures 1-6 As shown, the present invention provides a technical solution: a reverse umbrella rib processing and fixing device, including a worktable 1 and a controller (not shown in the figure) fixed on the top of the worktable 1. An insertion hole is provided in the middle of the worktable 1. It is known that the diameter of the umbrella handle 2 is smaller than the diameter of the insertion hole, so that the umbrella handle 2 can be movably inserted into the insertion hole. A U-shaped plate is fixed at the bottom of the worktable 1, and a rotating shaft is rolledly connected to the top of the U-shaped plate. A rotating disk 9 is fixed at the top of the rotating shaft. A clamping component 6 for clamping the umbrella handle 2 is provided at the top of the rotating disk 9. A lifting component 5 is provided on one side of the umbrella handle 2. It should be known that the lifting component 5 drives the pull ring 4 to move up and down along the handle body of the umbrella handle 2. A support component 8 is provided on the outside of the lifting component 5. The support component 8 supports the first connecting rod 301, thereby facilitating the connection between the first connecting rod 301 and the second connecting rod 302, as well as the connection of several subsequent connecting rods.

[0031] To reduce the intensity of work, such as Figure 1 and Figure 6 As shown, a U-shaped plate extends from the bottom rod of the rotating shaft, and a rotating assembly 7 is provided at its end. It should be noted that the rotating assembly 7 includes two vertical plates 701, a worm gear 702, a worm 703, and a motor 704. The worm 703 is rolled between the two vertical plates 701. The motor 704 is fixed to the side of the vertical plate 701, and its output end is fixed to the end of the worm 703. The worm gear 702 is fixed to the bottom end of the rotating shaft and meshes with the worm 703.

[0032] Specifically, the controller starts the motor 704, and when the motor 704 rotates, it drives the worm 703 to rotate. Since the worm wheel 702 and the worm 703 mesh, the rotating shaft drives the rotating disk 9 to rotate.

[0033] Understandably, the rotating assembly 7 can be replaced by two meshing gears or by the direct connection between the motor 704 and the reducer. However, since the worm gear 702 and the worm 703 mesh and have a self-locking property, the stability of the umbrella handle 2 after rotation can be guaranteed. Therefore, in this solution, the rotating assembly 7 preferably uses a combination of the worm gear 702 and the worm 703.

[0034] To clamp and fix the umbrella handle 2 so that it rotates synchronously with the rotating disk 9, as follows: Figure 1 , Figure 3 and Figure 6 As shown, the clamping assembly 6 includes a double-headed electric telescopic rod 601 and two movable plates 602. The two movable plates 602 are respectively fixed to the ends of the telescopic ends of the double-headed electric telescopic rod 601. The double-headed electric telescopic rod 601 is fixed to the top of the rotating disk 9. To improve the moving stability of the movable plates 602, a dovetail groove is provided on the top of the rotating disk 9. The movable plates 602 are adapted to the dovetail groove. A clamping roller 603 is rolledly connected to the top of the movable plates 602 through a first connecting shaft. It can be seen that the clamping rollers 603 are symmetrically arranged on both sides of the umbrella handle 2. In this way, when the two movable plates 602 move towards each other, the umbrella handle 2 is clamped by the clamping rollers 603.

[0035] Specifically, when the bottom of the umbrella handle 2 is at the top of the rotating disk 9, the double-headed electric telescopic rod 601 is started by the controller. The two moving plates 602 move towards each other under the push of the double-headed electric telescopic rod 601 until the two clamping rollers 603 clamp and fix the two sides of the umbrella handle 2.

[0036] At this time, the rotation of the rotating component 7 can realize the rotation of the umbrella handle 2.

[0037] To prevent deformation and damage to the umbrella handle 2 when the clamping roller 603 clamps and fixes it, in this solution, the clamping roller 603 is a rubber roller, and its surface is provided with anti-slip texture.

[0038] Since the servo motor can control speed and has relatively accurate position, in this solution, the number of umbrella ribs 3 is set to eight. When the controller controls the motor 704 to rotate, the umbrella handle 2 can be rotated 45 degrees with each rotation of the motor 704 using existing programming technology.

[0039] To achieve the up-and-down lifting of pull ring 4, such as Figure 2 and Figure 4As shown, the lifting assembly 5 includes a rectangular groove on the top of the worktable 1. A fixed shaft 501 is fixed between the walls of the rectangular groove. A slider 502 is movably connected to the shaft of the fixed shaft 501. A first spring 503 is fixed between the slider 502 and the wall of the rectangular groove. The fixed shaft 501 is located inside the spiral coil of the first spring 503. A single-headed electric telescopic rod 504 is fixed at the top of the slider 502. A top block 505 is fixed at the end of the telescopic end of the single-headed electric telescopic rod 504. An arc-shaped groove is opened on the side of the top block 505 relative to the pull ring 4. The arc-shaped groove is adapted to the connecting plate at the bottom of the pull ring 4, that is, the connecting plate at the bottom of the pull ring 4 is located in the arc-shaped groove. Straight grooves 507 are opened at the top and bottom of the arc-shaped groove. A rotating roller 508 is tumbledly connected in the straight groove 507 through a second connecting shaft. The top surface of the rotating roller 508 protrudes from the wall of the arc-shaped groove. A handle 506 is fixed on the outside of the top block 505.

[0040] It should be noted that when inserting the umbrella handle 2, the handle 506 is pulled by hand, the first spring 503 contracts, and the slider 502 moves to the left. After the umbrella handle 2 is fixed, the handle 506 is released, and when the first spring 503 returns to its original position, it drives the slider 502 to move to the right. At this time, the connecting plate at the bottom of the pull ring 4 is located in the arc groove.

[0041] For example, when the pull ring 4 is pulled, the controller controls the single-head electric telescopic rod 504 to extend, and the top of the bottom rotating roller 508 presses against the bottom of the connecting plate at the bottom of the pull ring 4, thereby lifting the pull ring 4. Since the rotating roller 508 and the pull ring 4 are in a rolling connection, the friction is small, so it will not affect the rotation of the umbrella handle 2.

[0042] The lifting assembly 5 pushes the pull ring 4 to move vertically along the handle 2, thereby adjusting the angle between the first connecting rod 301 and the second connecting rod 302. This facilitates the installation of the tension spring and related connecting parts of the automatic umbrella, further improving work efficiency. In addition, by driving the pull ring 4 to move vertically up and down along the handle 2, the lifting assembly 5 can simulate the process of closing and opening the umbrella, allowing for testing of the performance of the installed reverse umbrella rib 3 and timely detection of any installation problems.

[0043] To adjust the assembly angle of the first connecting rod 301 according to the worker's height or work habits, thereby further improving the practicality of the device, such as... Figure 2 and Figure 5As shown, the support assembly 8 includes two upright blocks 801. A stud 802 is rolledly connected to the inner side of one upright block 801. The stud 802 is movably inserted into the other upright block 801. A fastening nut 803 is screwed onto the column of the stud 802. A support part is fixed on the shaft of the stud 802. The support part supports the first connecting rod 301. The support part includes a socket rod and a telescopic shaft 804. The telescopic shaft 804 is movably inserted into the socket rod. A second spring 805 is fixed between the telescopic shaft 804 and the bottom wall of the socket rod slot. A U-shaped block 806 is fixed to the end of the telescopic shaft 804. A support roller 807 is rolledly connected between the U-shaped blocks 806 through a third connecting shaft.

[0044] Specifically, after the umbrella handle 2 and related components are installed, rotate the socket rod until the support roller 807 at the top of the telescopic shaft 804 contacts the bottom of the first connecting rod 301, and then tighten the fastening nut 803. At this time, the position of the socket rod is fixed, realizing the adjustment of the assembly angle of the first connecting rod 301.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
