Description

Technical Field

[0001] This utility model belongs to the technical field of wind chime processing equipment, and in particular relates to a wind chime tube assembly machine. Background Technology

[0002] A wind chime is an object that produces sound when the wind blows, and it is often used as an ornament. It makes a sound by the collision of various bells or other objects when the wind blows. There are many types of wind chimes, such as Japanese wind chimes and octagonal wind chimes. Wind chimes possess both visual beauty and auditory pleasure, making them excellent decorative items for the home.

[0003] Wind chimes are generally composed of several chime tubes suspended from a connector by a rope. Currently, most wind chime tubes on the market have holes drilled in them to insert pins for attaching the rope, or plastic eyelets are directly installed at the holes to connect the rope. However, drilling leaves marks on the outer wall of the chime tubes, damaging their overall appearance and affecting their aesthetics. Furthermore, the edges of the holes need to be polished after drilling, which is time-consuming and labor-intensive. In pin-type wind chimes, the rope can shift on the pin, affecting the sound quality, and the pin can easily fall off during wind chime movement, posing a safety hazard.

[0004] To address the aforementioned issues, a device for manufacturing novel wind chime tubes has emerged on the market. This device, patent number CN202210432516.8, is a Chinese utility model patent entitled "An Assembly Machine for Installing Snap Rings in Wind Chime Tubes." It discloses an assembly machine for installing snap rings in wind chime tubes, comprising a frame and mounted on the frame a feeding mechanism, a conveying mechanism, an inner groove digging mechanism, a spring-installing mechanism, and a discharging mechanism. The conveying mechanism transports the wind chime tubes from the feeding structure to the discharging mechanism. The inner groove digging mechanism and the spring-installing mechanism are sequentially arranged along the wind chime tube conveying stroke. The inner groove digging mechanism includes a groove cutter control and pushing device, a groove positioning device, and a three-jaw chuck. The spring-installing device includes a vibratory plate, a snap ring cylinder assembly, a snap ring gripping and pushing device, a flipping auxiliary device, and a driving device. However, the above solution requires first creating a groove on the inner wall of the wind chime tube using an internal trenching mechanism, and then pushing in the retaining spring to lock it in the groove. This method is not only cumbersome and inefficient, but also requires more components and has a relatively high failure rate. Therefore, a wind chime tube assembly machine with simple procedures, high efficiency, and low failure rate is needed. Utility Model Content

[0038] Through the above technical solution, compared with the prior art, this utility model has the following beneficial effects: A wind chime tube assembly machine, comprising a tube feeding mechanism, a conveying mechanism, a snap-fit ​​feeding mechanism, a pressing mechanism, and a discharging mechanism. The tube feeding mechanism is installed at the initial end of the frame, including a feeding rack for storing wind chime tubes, a lifting device for sequentially pushing the wind chime tubes out of the feeding rack, a sorting device for receiving the wind chime tubes at the lifting device and conveying them to the tube gripping device below, and a tube gripping device for gripping the wind chime tubes separated by the sorting device and placing them on the conveying mechanism. The conveying mechanism includes two sets of opposing sprocket assemblies, which are driven by sprockets. The machine is driven by a chain wheel assembly with tube seats on the chain. The tube seats on the two sets of chains correspond to each other. The tube gripping device grabs the wind chime tube from the material distribution device and places it on the tube seat. Then, the wind chime tube on the tube seat will move with the transmission direction of the chain to the space between the buckle feeding mechanism and the pressing mechanism. The buckle feeding mechanism includes a vibratory feeder, a buckle pushing module, and a buckle gripping device. The vibratory feeder is used to store and transport buckles. The buckle gripping device is used to clamp the buckles in the output slot of the vibratory feeder and place them at the pushing end of the buckle pushing module. The buckle pushing module pushes the buckles located in front of its pushing end into the body of the wind chime tube. The pressing mechanism serves to limit and abut the buckles.

[0039] Among them, the push rod in the pressing mechanism and the push rod in the buckle pushing module are set opposite to each other. When the tube seat with the wind chime tube body moves between the buckle pushing module and the pressing mechanism, the push material module in the pressing mechanism will be activated. The push rod on the push material module moves forward and extends into the tube body. After the push rod is in place, the buckle gripping device will grab the buckle located at the output slot of the vibrating plate and place it on the buckle fixture.

[0040] When the sensor at the clip fixture detects the clip, the clip pushing module is activated. The push rod in the clip pushing module moves the clip forward and into the tube body. The clip does not contact the inner wall of the tube body at first. When the push rod pushes the clip to abut against the top rod, it continues to apply pressure to the clip. At this time, the two sides of the clip, which were originally bent, will unfold outward until they abut against the inner wall of the tube body to form a locking state, thus fixing the tube body and the clip. After the clip is installed in place, the top rod and push rod withdraw from the tube body in sequence. Then, the sprocket assembly drives the assembled wind chime tube to continue moving to the discharge mechanism. The unloading gripping cylinder in the discharge mechanism grabs the wind chime tube located on the tube seat and puts it into the hopper to complete the entire wind chime tube assembly process.

[0041] The above-mentioned technical solution assembles the clips into the wind chime tube in a fully automated manner, reducing the existing multiple assembly processes to a single process. At the same time, it eliminates the need for an internal trenching mechanism and an upper spring mechanism, simplifying the entire installation process, reducing the overall failure rate, thereby increasing the production efficiency of the equipment. Moreover, the wind chime tubes produced are more robust, solving the technical problems of existing wind chime tube assembly equipment, which is not only cumbersome and inefficient but also requires many components and has a high failure rate.

[0061] like Figure 1-12 As shown: A wind chime tube assembly machine includes a frame 1, on which a tube feeding mechanism, a conveying mechanism, a snap-fit ​​feeding mechanism, a pressing mechanism, and a discharging mechanism are installed. In this embodiment, the frame 1 is provided with an outer frame 100, which has an inlet and an outlet. The tube feeding mechanism and the discharging mechanism are respectively located at the inlet and outlet. The outer frame 100 is provided with a main control device 110, which has a touch panel for human-machine interaction. The main control device 110 controls the tube feeding mechanism, the conveying mechanism, the snap-fit ​​feeding mechanism, the pressing mechanism, and the discharging mechanism through a PLC to achieve fully automated wind chime tube conveying and snap-fit ​​positioning and installation, with a very high degree of automation.

[0062] The tube feeding mechanism is installed at the initial end of the frame and is used for storing and feeding the bell tubes;

[0063] The conveying mechanism is used to receive the wind chime tubes output by the self-tube feeding mechanism and transport the wind chime tubes to the discharge mechanism. During the conveying process of the wind chime tubes, they will pass between the snap-feeding mechanism and the pressing mechanism.

[0064] The clip-on feeding mechanism includes:

[0065] Vibrating plate 2, used for storage and output latches;

[0066] The buckle pushing device 3 is used to push the buckle in and engage it in the wind chime tube.

[0067] The buckle gripping device 4 is used to grip the buckle from the discharge chute of the vibrating plate 2 and place it at the pushing end of the buckle pushing device 3.

[0068] The pressing mechanism and the buckle pushing device 3 are arranged opposite to each other. The pressing mechanism extends from the pipe opening away from the buckle pushing device 3 to limit the buckle's contact.

[0069] The unloading mechanism is used to output the assembled snap-fit ​​wind chime tubes.

[0070] like Figure 1-5 As shown: The tube feeding mechanism includes a feeding rack 5, a lifting device 6, a distributing device 7, and a tube gripping device 8;

[0071] The feeding rack 5 is used to store the wind chime tube body; in this embodiment, the feeding rack 5 is installed on one side of the feeding port, and a support frame for supporting the feeding rack 5 is provided below the feeding rack 5.

[0072] like Figure 6 As shown: The lifting device 6 includes a mounting frame 601 and several movable top rods 602 that are longitudinally staggered and arranged side by side in the transverse direction, mounted on the mounting frame 601, a lifting cylinder 603 that drives all the movable top rods 602 to move up and down synchronously, and a guide plate 604 arranged obliquely for the wind chime tube to slide down.

[0073] In this embodiment, the mounting frame 601 includes a fixing plate 605, a lifting cylinder 603 is installed at the lower end of the fixing plate 605, a connecting plate 606 is connected to the upper end of the fixing plate 605, a plurality of movable top plates 607 are fixedly provided on the upper end of the connecting plate 606, a plurality of movable top rods 602 are all installed above the movable top plates 607, and a partition 608 is provided between the movable top rods 602. The upper end surfaces of the partition 608 and the movable top rods 602 are inclined and smoothly transition to each other. The partition 608 is fixedly installed on the mounting frame 601.

[0074] The lifting cylinder 603 is fixed by the fixing plate 605 and is used to drive the connecting plate 606 to move up and down. When the connecting plate 606 moves upward, it will drive the movable top plate 607 to move upward, and then drive the movable top rod 602 to move upward. Since the upper end surfaces of the partition plate 608 and the movable top rod 602 are both inclined, the wind chime tube that enters the upper end surface of the partition plate 608 will roll to the upper end surface of the movable top rod 602. The partition plate 608 is used as a limit. When the movable top rod 602 moves upward to connect to the upper end surface of the next partition plate 608, the wind chime tube will continue to move and roll to the upper end surface of the next partition plate 608, and so on. Finally, the wind chime tube will be gradually conveyed to the material distribution device 7.

[0075] The material distribution device 7 includes a material distribution plate 701 for conveying the wind chime tube to the tube gripping device 8 below and a material ejection module for ejecting the wind chime tube upwards.

[0076] like Figure 7As shown: In this embodiment, the top material module includes a push block 702 and a top material cylinder 703. The upper end of the material distribution plate 701 is provided with a first material distribution slot 704 and a second material distribution slot 705. After being guided by the guide plate 604, the wind chime tube will first be stuck in the first material distribution slot 704. The top material cylinder 703 drives the push block 702 to move upward, thereby pushing the wind chime tube upward. At this time, the wind chime tube will pass through the first material distribution slot 704 and enter the second material distribution slot 705. After the wind chime tube enters the second material distribution slot 705, the tube gripping device 8 will remove the wind chime tube here. The top material module is fixed on both sides of the wind chime tube conveying direction by the mounting base. In this embodiment, a first sensor for triggering the top material cylinder 703 is provided between the first material distribution slots 704 on both sides, and a second sensor for triggering the tube gripping device 8 is provided between the second material distribution slots 705.

[0077] like Figure 7 As shown: The tube gripping device 8 includes a robotic arm module 801 and a linear drive module 802 for driving the robotic arm module 801. The robotic arm module 801 is used to grip and move the wind chime tube located on the material distribution plate 701 to the conveying mechanism. In this embodiment, the linear drive module 802 includes a guide rail mounting plate 803 and a tube gripping first drive cylinder 804. The guide rail mounting plate 803 is provided with a guide rail, and a slider is movably provided on the guide rail. A drive plate is mounted on the slider. The tube gripping first drive cylinder 804 is used to drive the drive plate to move on the guide rail.

[0078] The robotic arm module 801 includes a support frame 805, which is mounted on a drive plate. A second drive cylinder 806 for gripping the tube is mounted above the support frame 805. At least one third drive cylinder 807 for gripping the tube is mounted in the support frame 805. A gripper 808 is provided at the lower end of the third drive cylinder 807. The third drive cylinder 807 is used to drive the gripper 808 to work. The second drive cylinder 806 is used to drive the support frame 805 to move up and down, and finally transport the wind chime tube held by the gripper 808 to the conveying mechanism.

[0079] It should be noted that the aforementioned material distribution plate 701 and guide rail mounting plate 803, as well as their corresponding structures, are all installed symmetrically front and back to ensure that the wind chime tube can be moved and transported smoothly.

[0080] Here, a feeding sensor is usually installed between the tube gripping device 8 and the conveying mechanism. When the feeding sensor does not detect that a bell tube is placed on the conveying mechanism, it will automatically alarm. This usually indicates that there is a problem in one of the processes of the tube feeding mechanism, which can help troubleshoot the machine malfunction in a timely manner.

[0081] like Figure 3-5As shown: The conveying mechanism includes at least two sprocket assemblies 9 arranged and operating synchronously along the conveying direction of the wind chime tube, a sprocket drive motor 901 for driving the sprocket assemblies 9, and tube seats 902 evenly spaced on the chain of the sprocket assemblies 9. The tube seats 902 located on different sprocket assemblies 9 correspond one-to-one along the axial direction of the wind chime tube and are used together to support and place the wind chime tube.

[0082] Generally, the sprocket assembly 9 includes one driving sprocket and multiple driven sprockets. The driving sprocket is connected to the sprocket drive motor 901, and the driving sprocket and driven sprockets are connected by a transmission rod. The chain typically has two sets, symmetrically arranged front and rear. All sprockets on the chain except for the driving sprocket are driven sprockets. When one of the driving sprockets is driven to rotate by the sprocket drive motor 901, it drives the corresponding driven sprocket 4 to rotate via the transmission rod. The driven sprockets on the same chain as the driving sprocket also rotate, causing both chains to rotate synchronously. Consequently, the tube holders 902 mounted on both chains also rotate synchronously, ensuring the smooth and directional transport of the wind chime tube.

[0083] like Figure 9-10 As shown: The buckle pushing device 3 includes a base 301 disposed on one side of the sprocket assembly 9 and a buckle pushing module 302 mounted on the base 301. The pushing end of the buckle pushing module 302 is provided with a push rod seat 303. The push rod seat 303 is provided with a push rod 304 corresponding to the tube seat 902. The base 301 is also provided with a buckle placement frame 305. The buckle placement frame 305 is located at the front end of the buckle pushing module 302. The buckle placement frame 305 is provided with a buckle clamp 306. The buckle clamp 306 is provided with a guide groove 307. The guide groove 307 and the push rod 304 are correspondingly arranged. The guide groove 307 is used for placing the buckle and pushing the push rod 304.

[0084] In this embodiment, the buckle push module 302 includes a mold frame, a push end is movably provided on the mold frame, a servo motor is provided on one side of the mold frame for driving the push end to move in the horizontal direction of the mold frame, and a sensor is provided at the guide groove 307.

[0085] like Figure 9-10As shown: The buckle gripping device 4 includes a material picker 401, a slide rail 402 on the material picker 401, a drive block on the slide rail 402, a first push cylinder 403 on one side of the material picker 401 for driving the drive block to move left and right, a second push cylinder 404 on the drive block, a connecting plate 405 on the pushing end of the second push cylinder 404, a rotary cylinder 406 on the connecting plate 405, and a flipping material picker mechanism 407 on the rotating end of the rotary cylinder 406. The second push cylinder 404 controls the flipping material picker mechanism 407 to move up and down, and the rotary cylinder 406 controls the flipping material picker mechanism 407 to rotate to the discharge slot of the vibrating plate 2 to pick up the material. The flipping material picker mechanism 407 is a rotary clamping finger cylinder used to adjust the direction of the buckle. In this embodiment, the buckle is gripped by opening and closing the clamp on the clamping end of the rotary clamping finger cylinder, and the position of the buckle is adjusted by rotating the clamping finger cylinder to ensure that it can be accurately snapped into the tube body.

A gripping groove 2008 corresponding to the clearance groove is provided on the guiding block 2007. The gripping groove 2008 is used to guide the gripping part of the flipping material handling mechanism to the bottom of the buckle.

[0096] It also includes sensors, which are installed on both sides of the discharge rack 2001 to sense the position of the buckle in order to control the buckle gripping device 4.

[0097] like Figure 12 As shown: The discharge mechanism includes a finished product picking rack 300 located at the end of the frame 1, a linear drive module 3001 located on the finished product picking rack 300, and a hopper 3002. The finished product picking rack 300 is used to fix the linear drive module 3001. The linear drive module 3001 controls the left and right movement of the discharge cylinder frame 3003 through a cylinder. The linear drive module 3001 is existing technology.

[0098] The linear drive module 3001 is equipped with a drive end whose left and right movements are controlled by a cylinder, and the drive end is equipped with a discharge cylinder frame 3003.

[0099] The discharge cylinder frame 3003 is equipped with a finished product unloading cylinder 3004. The push end of the finished product unloading cylinder 3004 is equipped with a push plate 3005. On both sides of the push plate 3005, there is a unloading gripping cylinder 3006. The drive end of the unloading gripping cylinder 3006 is equipped with a clamp for gripping the wind chime tube. The discharge mechanism and the tube gripping device 8 have the same structure.

[0100] like Figure 1-3 As shown: the hopper 3002 is used to store the wind chime tubes assembled with buckles, and the feeding gripping cylinder 3006 is used to grip the wind chime tubes into the hopper 3005. In this embodiment, a support frame is provided below the hopper 3005, and the hopper 3005 is correspondingly set at the discharge port.

[0101] like Figure 3 As shown: The frame 1 is provided with an adjustment frame 40, which is movable on the frame 1 by a drive mechanism. The sprocket assembly 9 is provided with a first transmission group and a second transmission group. The second transmission group is installed on the adjustment frame 40.

[0102] like Figure 3 As shown: The drive mechanism includes an adjustment frame drive module 4003 and a sliding assembly. The adjustment frame drive module 4003 is mounted on the frame 1. The push end of the adjustment frame drive module 4003 is fixedly connected to one end of the adjustment frame 40. The sliding assembly includes a guide rail mounted on the frame 1 and a slider mounted below the adjustment frame 40. The adjustment frame 40 is slidably connected through the cooperation of the guide rail and the slider.

[0103] In addition, the buckle in this utility model includes a suspension part and abutment parts located on both sides of the suspension part. The abutment parts have several upwardly bent claws. The claws contact and fit with the inner wall of the tube to restrict the buckle inside the tube. When the buckle is in the initial state, its abutment parts are closed together and bent. When the push rod 304 pushes the buckle into the tube, the buckle is initially in an unopened state, and the abutment parts on both sides do not contact the inner wall of the tube. When the suspension part on the rear side of the buckle abuts with the top rod 13, the push rod 304 continues to apply pressure, thereby forcing the abutment parts in the folded state to extend to both sides until the claws on the abutment parts abut with the inner wall of the tube, thereby realizing the fixed installation of the buckle.

[0104] The beneficial effects of this utility model are as follows:

[0105] A wind chime tube assembly machine comprises a tube feeding mechanism, a conveying mechanism, a snap-fit ​​feeding mechanism, a pressing mechanism, and a discharging mechanism. The tube feeding mechanism is installed at the initial end of the frame 1 and includes a feeding rack 5 for storing wind chime tubes, a lifting device 6 for sequentially ejecting wind chime tubes from the feeding rack 5, a sorting device 7 for receiving wind chime tubes from the lifting device 6 and conveying them to a tube gripping device 8 below, and a tube gripping device 8 for gripping the wind chime tubes separated by the sorting device 7 and placing them on the conveying mechanism. The conveying mechanism includes two sets of opposing sprocket assemblies 9, which are driven by a sprocket drive motor 901. Tube seats 90 are provided on the chains of the sprocket assemblies 9. 2. The tube seats 902 on the two sets of chains correspond to each other. After the tube gripping device 8 grips the wind chime tube from the material distribution device 7, it is placed on the tube seat 902. Then, the wind chime tube on the tube seat 902 will move between the buckle feeding mechanism and the pressing mechanism following the transmission direction of the chain. The buckle feeding mechanism includes a vibrating plate 2, a buckle pushing module 3 and a buckle gripping device 4. The vibrating plate 2 is used to store and transport buckles. The buckle gripping device 4 is used to clamp the buckles in the output slot of the vibrating plate 2 and place them at the pushing end of the buckle pushing module 3. The buckle pushing module 3 pushes the buckles located in front of its pushing end into the body of the wind chime tube. The pressing mechanism plays a role in limiting and abutting the buckles.

[0106] Among them, the push rod 13 in the pressing mechanism and the push rod 304 in the buckle pushing module 3 are arranged opposite to each other. When the pipe seat 902 with the wind chime tube body moves between the buckle pushing module 3 and the pressing mechanism, the top material module 10 in the pressing mechanism will be activated. The push rod 13 on the top material module 10 moves forward and extends into the tube body. After the push rod 13 is in place, the buckle gripping device 8 will grab the buckle located at the output slot of the vibrating plate 2 and place it on the buckle clamp 306.

[0107] When the sensor at the buckle clamp 306 detects the buckle, the buckle pushing module 3 is activated. The push rod 304 in the buckle pushing module 3 drives the buckle forward and into the tube body. The buckle does not contact the inner wall of the tube body when it first enters the tube body. When the push rod 304 pushes the buckle to abut against the top rod 13, it will continue to apply pressure to the buckle. At this time, the two sides of the buckle, which were originally bent, will unfold outward until they abut against the inner wall of the tube body to form a snap-fit ​​state, thus realizing the fixed installation of the tube body and the buckle. After the buckle is installed in place, the top rod 10 and the push rod 304 exit the tube body in sequence. Then, the sprocket assembly 9 drives the assembled wind chime tube to continue moving to the discharge mechanism. The unloading gripping cylinder 3006 in the discharge mechanism grabs the wind chime tube located on the tube seat 902 and puts it into the hopper to complete the entire wind chime tube assembly process.

[0108] The above-mentioned technical solution assembles the clips into the wind chime tube in a fully automated manner, reducing the existing multiple assembly processes to a single process. At the same time, it eliminates the need for an internal trenching mechanism and an upper spring mechanism, simplifying the entire installation process, reducing the overall failure rate, thereby increasing the production efficiency of the equipment. Moreover, the wind chime tubes produced are more robust, solving the technical problems of existing wind chime tube assembly equipment, which is not only cumbersome and inefficient but also requires many components and has a high failure rate.

[0109] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
