Description

Technical Field

[0001] This utility model belongs to the technical field of locking assembly equipment, and in particular relates to a locking assembly structure. Background Technology

[0002] A latch is a device used to fasten two items together. It generally consists of a movable part and a fixed part, and is used to fasten the movable part and the fixed part together.

[0003] The fixing part is generally made up of fasteners and fixing plates welded together. However, the traditional assembly process of fasteners and fixing plates mostly relies on manual operation or semi-automated equipment. When operating manually, workers need to place the fasteners in the designated positions, then stack the fixing plates one by one, and then perform welding and cutting. This is not only labor-intensive and inefficient, but also prone to deviations in the assembly position of the fasteners and fixing plates due to human error, affecting the welding quality and product consistency.

[0004] While some semi-automated equipment can mechanize certain processes, there is a lack of effective linkage and coordination between the various stages. For example, the buckle feeding mechanism, the fixed plate feeding mechanism, and the welding mechanism often operate independently, requiring manual assistance for workpiece transfer and positioning, making it difficult to form a continuous production process. At the same time, the feeding mechanisms of existing equipment mostly use linear conveyors, which occupy a large space and cannot achieve multi-station parallel operation, resulting in limited output per unit time.

[0005] Furthermore, during the loading of the fixing plate, the lack of a precise positioning structure can easily lead to problems such as the fixing plate being misaligned or placed incorrectly, further affecting the stability of subsequent welding processes. During welding, if the fastener and the fixing plate are not securely fastened, vibrations during the welding process can cause workpiece displacement, resulting in welding defects and increasing the product rejection rate.

[0006] To address the aforementioned issues and improve the automation level, production efficiency, and product quality of buckle assembly, there is an urgent need for a buckle assembly structure that can automate the entire process of buckle feeding, fixing plate loading, welding, and unloading, while ensuring precise linkage between each process.

[0007] Therefore, we need to design a locking assembly structure to solve these problems. Utility Model Content

[0008] The problem to be solved by this utility model is to provide a locking assembly structure.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0010] A latch assembly structure includes a housing. A feeding mechanism is provided in the middle of the housing. A latch ring feeding mechanism, a fixing plate feeding mechanism, a welding mechanism, and a discharging mechanism are arranged sequentially along the feeding direction of the feeding mechanism. The latch ring feeding mechanism is used to feed latch rings onto the feeding mechanism. The fixing plate feeding mechanism is used to feed fixing plates onto the latch rings of the feeding mechanism. The welding mechanism is used to weld the latch rings and fixing plates on the feeding mechanism. The discharging mechanism is used to remove the welded latch rings and fixing plates from the feeding mechanism.

[0011] Preferably, the feeding mechanism includes a rotary motor fixed to the top of the machine housing, a rotating disk fixedly mounted on the output end of the rotary motor, a plurality of clamping seats fixedly mounted on the rotating disk, clamping plates slidably mounted on the clamping seats, tension springs and rollers mounted on the clamping plates, the free end of the tension springs being connected to the clamping seats, and a clamping cylinder fixedly mounted on the machine housing below the rollers, with a push rod fixedly mounted on the output end of the clamping cylinder.

[0012] This design, with its rotary motor-driven rotating disk feeding mechanism, saves more space compared to linear feeding. Multiple clamping seats on the rotating disk can simultaneously hold workpieces, allowing different processes such as loading, welding, and unloading to be processed in parallel, thus improving output efficiency per unit time. The clamping plates on the clamping seats, through the cooperation of tension springs and the push rod of the clamping cylinder, achieve automatic clamping and unloading of workpieces: the tension springs ensure that the clamping plates have a pre-tension force on the workpiece under normal conditions, and the clamping cylinder drives the rollers to open the clamping plates via the push rod, adapting to the clamping requirements of workpieces of different specifications. The clamping is stable and the operation is automated, reducing the time cost and errors of manual clamping.

[0013] Preferably, the buckle feeding mechanism includes a buckle mounting frame fixed on the chassis, a buckle lateral movement component fixedly mounted on the buckle mounting frame, a buckle lifting component mounted on the buckle lateral movement component, a buckle clamping cylinder mounted on the buckle lifting component, a buckle gripper at the output end of the buckle clamping cylinder, a buckle feeding tray on one side of the chassis, a buckle positioning seat at the output end of the buckle feeding tray, a material transfer mounting seat on one side of the positioning seat on the chassis, a buckle transfer cylinder mounted on the material transfer mounting seat, and a buckle distribution frame fixedly mounted at the output end of the buckle transfer cylinder.

[0014] This configuration allows the buckle feeding mechanism to flexibly move the buckle grippers horizontally and vertically through a combination of buckle lateral movement and lifting components. This enables precise transfer of buckles from the feeding tray to designated positions within the feeding mechanism, adapting to the positional requirements of different workstations. The buckle feeding tray continuously supplies material for the feeding process. Combined with the buckle transfer cylinder and lock, buckle positioning seat, and buckle separator, the sequentially fed buckles can be separated one by one, preventing issues like multiple buckles or jamming during feeding. This ensures that only one buckle is fed at a time, improving feeding accuracy and stability and reducing the risk of failure in subsequent processes.

[0015] Preferably, the fixed plate feeding mechanism includes a fixed plate mounting frame fixedly mounted on the chassis, a fixed plate transverse moving assembly fixedly mounted on the fixed plate mounting frame, a fixed plate lifting assembly mounted on the fixed plate transverse moving assembly, a fixed plate clamping cylinder mounted on the fixed plate lifting assembly, a fixed plate gripper mounted on the fixed plate clamping cylinder, a fixed plate claw mounted at the output end of the fixed plate clamping cylinder, a fixed plate feeding tray mounted on one side of the chassis, a fixed plate positioning seat mounted at the output end of the fixed plate feeding tray, a fixed plate transferring cylinder mounted on one side of the fixed plate positioning seat, a transferring push plate mounted at the output end of the fixed plate transferring cylinder, and the free end of the transferring push plate located on the fixed plate positioning seat.

[0016] With this configuration, the fixed plate feeding tray in the fixed plate feeding mechanism provides a continuous supply of fixed plates. The fixed plate positioning seat precisely positions the delivered fixed plates, and in conjunction with the material transfer push plate of the fixed plate transfer cylinder, the positioned fixed plate can be stably pushed to the gripping position, avoiding positional deviations that occur during manual placement. Meanwhile, the fixed plate lateral movement component and lifting component drive the fixed plate gripper to move flexibly, accurately gripping the fixed plate and placing it on the buckle of the feeding mechanism. The entire process is highly automated, with high positioning accuracy, effectively ensuring the accurate assembly of the buckle and the fixed plate.

[0017] Preferably, the welding mechanism includes a welding bracket and a welding support base fixed on the chassis. A clamping cylinder is fixedly mounted on the welding support base, and a pressure plate is fixedly mounted on the output end of the clamping cylinder. A welding groove is formed on the pressure plate. A lifting frame is mounted on the welding bracket, and a welding translation cylinder and a welding connecting frame are mounted on the lifting frame. The welding connecting frame is slidably connected to the lifting frame, and the output end of the welding translation cylinder is connected to the welding connecting frame. A welding device is fixedly mounted on the welding connecting frame, and the output end of the welding device is located above the welding groove.

[0018] This configuration, using a clamping cylinder to drive the pressure plate, tightly secures the buckle and the fixing plate, preventing welding deviations caused by workpiece displacement during welding and improving welding accuracy. The welding groove on the fixing plate precisely exposes the area to be welded, allowing the welding device to directly target the welding point and avoid damage to non-welding areas. Simultaneously, the welding translation cylinder and lifting frame adjust the welding device's position horizontally and vertically, adapting to the welding needs of buckles and fixing plates of different specifications, thus enhancing the equipment's versatility and the stability of welding quality.

[0019] Preferably, the feeding mechanism includes a feeding bracket fixed on the chassis, a feeding cylinder and a guide trough fixedly mounted on the feeding bracket, the feeding cylinder being located above the guide trough, and a feeding pusher fixedly mounted at the output end of the feeding cylinder.

[0020] With this configuration, the unloading mechanism, driven by an unloading cylinder, can quickly push the welded finished product from the feeding mechanism to the guide chute, achieving automated unloading without manual handling, thus reducing manual intervention and labor intensity. The guide chute guides the finished product to slide orderly into the collection area, preventing collision damage during drop and ensuring the integrity of the finished product. It also improves unloading efficiency and creates a smooth connection with previous processes.

[0021] Preferably, a controller is fixedly installed on the chassis, and the controller is electrically connected to the feeding mechanism, the buckle loading mechanism, the fixed plate loading mechanism, the welding mechanism and the unloading mechanism respectively.

[0022] With this setup, the controller is electrically connected to each mechanism, enabling unified and coordinated control of the timing of actions in each stage, such as feeding, loading, welding, and unloading. This ensures that each mechanism works precisely according to the preset process, achieving fully automated production. This centralized control method not only reduces errors from manual operation but also allows for rapid adaptation to different production needs through program adjustments, facilitating equipment debugging and maintenance, while simultaneously improving equipment stability and production consistency.

[0023] Preferably, a positioning block is also provided at the output end of the fixed plate clamping cylinder, and the positioning block is located inside the fixed plate clamping claw.

[0024] With this configuration, the positioning block at the output end of the clamping cylinder is located inside the clamping jaws of the fixed plate. When the jaws grip the fixed plate, the positioning block assists in precise positioning of the fixed plate, ensuring that the jaws grip the fixed plate consistently and preventing positional deviations when placing it on the retaining ring due to gripping misalignment. This design further improves the assembly accuracy of the retaining ring and the fixed plate, ensuring stable quality in subsequent welding processes and enhancing the overall assembly quality of the product.

[0025] The advantages and positive effects of this utility model are:

[0026] The overall structure of this utility model is based on a chassis, with the feeding mechanism as the core conveying carrier. Along the feeding direction, the buckle feeding, fixing plate feeding, welding and unloading mechanisms are arranged in sequence, forming a complete automated assembly line. This ensures that each process is closely connected and realizes continuous operation of buckles from feeding to unloading the final product. It greatly reduces manual intervention, which not only improves production efficiency, but also ensures the consistency of product assembly through standardized processes and reduces errors caused by manual operation.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The present invention will be further described below with reference to the accompanying drawings:

[0043] Example 1: As Figure 1 As shown, a locking assembly structure includes a housing 1. A feeding mechanism 2 is provided in the middle of the housing 1. Along the feeding direction of the feeding mechanism 2, a buckle loading mechanism 3, a fixing plate loading mechanism 4, a welding mechanism 5, and a unloading mechanism 6 are arranged in sequence. The feeding mechanism 2 connects each process mechanism in sequence. The buckle loading mechanism 3 is used to transport buckles to the feeding mechanism 2. When loading buckles, the buckle loading mechanism 3 needs to be aligned with the initial position of the feeding mechanism 2 to complete the buckle placement. The fixing plate loading mechanism 4 is then connected to the position after the buckle loading to realize the stacking of fixing plates. Then, the welding mechanism 5 performs welding operations at the corresponding position after stacking. Finally, the unloading mechanism 6 removes the finished product at the position after welding. The mechanisms are arranged in sequence along the feeding direction to form a closed-loop process of continuous operation.

[0044] The feeding mechanism 2 includes a rotary motor 201 fixed on the top of the housing 1. A rotating disk 202 is fixedly installed at the output end of the rotary motor 201. Several clamping seats 203 are fixedly installed on the rotating disk 202. Clamping plates 205 are slidably installed on the clamping seats 203. Tension springs 204 and rollers 207 are installed on the clamping plates 205. The free end of the tension springs 204 is connected to the clamping seats 203. A clamping cylinder 206 is fixedly installed on the housing 1 below the rollers 207. A push rod 208 is fixedly installed at the output end of the clamping cylinder 206.

[0045] When the rotary motor 201 drives the rotating disk 202 to rotate, the clamping seat 203 moves synchronously with the rotating disk 202. When the clamping seat 203 reaches the designated work position, the clamping cylinder 206 is activated, and the push rod 208 pushes the roller 207 upward, causing the clamping plate 205 to slide open against the tension of the tension spring 204. After the workpiece is placed in, the clamping cylinder 206 resets, and the tension spring 204 pulls the clamping plate 205 to close and clamp the workpiece. The arrangement of multiple clamping seats 203 allows other clamping seats 203 to perform welding or unloading operations simultaneously while one clamping seat 203 is performing a loading operation. The various components achieve continuous conveying and positioning of the workpiece through mechanical linkage.

[0046] The buckle feeding mechanism 3 includes a buckle mounting bracket 303 fixed on the chassis 1. A buckle transverse moving component 304 is fixedly mounted on the buckle mounting bracket 303. A buckle lifting component 305 is mounted on the buckle transverse moving component 304. A buckle clamping cylinder 306 is mounted on the buckle lifting component 305. A buckle gripper 302 is mounted on the output end of the buckle clamping cylinder 306. A buckle feeding tray 301 is mounted on one side of the chassis 1. A buckle positioning seat 309 is mounted on the output end of the buckle feeding tray 301. A material transfer mounting seat 308 is mounted on one side of the positioning seat of the chassis 1. A buckle transfer cylinder 307 is mounted on the material transfer mounting seat 308. A buckle distributing rack 310 is fixedly mounted on the output end of the buckle transfer cylinder 307.

[0047] The buckle is fed to the buckle positioning seat 309 by the buckle feeding tray 301. The buckle positioning seat 309 separates and sorts the buckles. Then, the buckle transfer cylinder 307 drives the buckle distribution frame 310 to move, pushing the buckle on the buckle positioning seat 309 to the gripping position. The buckle lateral movement component 304 drives the buckle lifting component 305 to move above the buckle distribution frame 310. The buckle lifting component 305 drives the buckle clamping cylinder 306 to descend. The buckle gripper 302 grips the buckle under the drive of the buckle clamping cylinder 306. Then, the buckle lifting component 305 rises, and the buckle lateral movement component 304 moves the buckle to the gripping seat 203 of the feeding mechanism 2. The buckle lifting component 305 descends again, and the buckle gripper 302 releases to complete the buckle placement. The various components achieve precise transfer of the buckle from feeding to loading through the action connection.

[0048] The fixed plate feeding mechanism 4 includes a fixed plate mounting frame 405 fixedly mounted on the chassis 1. A fixed plate transverse moving assembly 406 is fixedly mounted on the fixed plate mounting frame 405. A fixed plate lifting assembly 407 is mounted on the fixed plate transverse moving assembly 406. A fixed plate clamping cylinder 408 is mounted on the fixed plate lifting assembly 407. A fixed plate gripper 409 is mounted at the output end of the fixed plate clamping cylinder 408. A fixed plate feeding tray 401 is mounted on one side of the chassis 1. A fixed plate positioning seat 402 is mounted at the output end of the fixed plate feeding tray 401. A fixed plate transferring cylinder 403 is mounted on one side of the fixed plate positioning seat 402. A transferring push plate 404 is mounted at the output end of the fixed plate transferring cylinder 403. The free end of the transferring push plate 404 is located on the fixed plate positioning seat 402.

[0049] The fixed plate is conveyed to the fixed plate positioning seat 402 by the fixed plate feeding tray 401. The fixed plate transfer cylinder 403 drives the transfer push plate 404 to push the fixed plate to the gripping position of the positioning seat. The fixed plate lateral movement component 406 drives the fixed plate lifting component 407 to move above this position. The fixed plate lifting component 407 drives the fixed plate clamping cylinder 408 to descend. After the fixed plate gripper 409 grips the fixed plate, the fixed plate lifting component 407 rises. The fixed plate lateral movement component 406 moves the fixed plate to the top of the buckle on the feeding mechanism 2. Finally, the fixed plate and the buckle are accurately superimposed by the descent of the fixed plate lifting component 407 and the release of the gripper. The action sequence of each component matches the station conversion of the feeding mechanism 2.

[0050] The welding mechanism 5 includes a welding bracket 501 and a welding support base 507 fixed on the housing 1. A clamping cylinder 508 is fixedly installed on the welding support base 507. A pressure plate 509 is fixedly installed at the output end of the clamping cylinder 508. A welding groove 510 is opened on the pressure plate 509. A lifting frame 503 is installed on the welding bracket 501. A welding translation cylinder 505 and a welding connecting frame 504 are installed on the lifting frame 503. The welding connecting frame 504 is slidably connected to the lifting frame 503. The output end of the welding translation cylinder 505 is connected to the welding connecting frame 504. A welding device 506 is fixedly installed on the welding connecting frame 504. The output end of the welding device 506 is located above the welding groove 510.

[0051] When the feeding mechanism 2 delivers the buckle with the fixed plate stacked on it to the welding station, the clamping cylinder 508 drives the pressure plate 509 to descend, pressing and fixing the buckle to the fixed plate. The welding translation cylinder 505 pushes the welding connecting frame 504 to slide along the lifting frame 503, adjusting the horizontal position of the welding device 506. At the same time, the lifting frame 503 adjusts the height of the welding device 506 so that the output end of the welding device 506 is aligned with the welding groove 510 on the fixed plate. The contact part between the buckle and the fixed plate is welded through the welding groove 510. After the welding is completed, the clamping cylinder 508 resets. The linkage of each component realizes the precise control of the welding process.

[0052] An adjustment handle 502 is also provided on the welding bracket 501. In this embodiment, the welding handle is connected to the lifting frame 503 by a screw. By rotating the adjustment handle 502, the height of the lifting frame 503 can be adjusted, thereby realizing the adjustment of the height of the welding device 506 to match the welding of buckles and fixing plates of different sizes.

[0053] The feeding mechanism 6 includes a feeding bracket 601 fixed on the housing 1. A feeding cylinder 602 and a guide trough 604 are fixedly installed on the feeding bracket 601. The feeding cylinder 602 is located above the guide trough 604, and a feeding pusher 603 is fixedly installed at the output end of the feeding cylinder 602.

[0054] When the feeding mechanism 2 transports the welded workpiece to the unloading station, the clamping cylinder 206 drives the push rod 208 to lift the roller 207, causing the clamping plate 205 to open. The unloading cylinder 602 is activated, driving the unloading pusher 603 to push the workpiece from the clamping seat 203 to the guide groove 604. The workpiece slides down the guide groove 604 to the collection area. The action of the unloading pusher 603 is coordinated with the workpiece positioning of the feeding mechanism 2 to realize the automatic unloading of the finished product.

[0055] A controller 7 is fixedly installed on the chassis 1. The controller 7 is electrically connected to the feeding mechanism 2, the buckle feeding mechanism 3, the fixed plate feeding mechanism 4, the welding mechanism 5, and the unloading mechanism 6.

[0056] The controller 7 sends electrical signals to each mechanism through a preset program to coordinate the rotation angle of the rotary motor 201, the extension and retraction timing of the clamping cylinder 206, and the action sequence of each clamping cylinder. When a mechanism completes a preset action, the controller 7 receives a feedback signal and triggers the action of the next mechanism. The automatic linkage of each mechanism is realized through the transmission of electrical signals, ensuring that the entire assembly process proceeds according to the predetermined rhythm.

[0057] A positioning block 410 is also provided at the output end of the fixed plate clamping cylinder 408, and the positioning block 410 is located inside the fixed plate clamping claw 409.

[0058] When the fixed plate gripper 409 grips the fixed plate, the positioning block 410 contacts the inner edge of the fixed plate, limiting the fixed plate and ensuring that the fixed plate is fixed in the gripper. When the fixed plate is placed on the buckle, the positioning function of the positioning block 410 can ensure the accurate relative position of the fixed plate and the buckle, providing a structural basis for the precise docking of subsequent welding processes, and improving the assembly accuracy in conjunction with the fixed plate gripper 409.

[0059] The working process of this embodiment is as follows: During operation, the feeding mechanism 2 is started first, and the rotary motor 201 drives the rotating disk 202 to rotate, so that the clamping seats 203 on the rotating disk 202 pass through each process station in sequence. When one of the clamping seats 203 reaches the buckle loading station, the clamping cylinder 206 drives the push rod 208 to push the roller 207 upward, and the clamping plate 205 slides open against the tension of the tension spring 204, preparing to receive the buckle.

[0060] At this time, the buckle feeding mechanism 3 begins to work. The buckle feeding tray 301 conveys the buckles to the buckle positioning seat 309, which separates and arranges the buckles. Then, the buckle transfer cylinder 307 drives the buckle distribution frame 310 to move, pushing the buckles on the buckle positioning seat 309 to the gripping position. Subsequently, the buckle lateral movement component 304 drives the buckle lifting component 305 to move above the buckle distribution frame 310. The buckle lifting component 305 drives the buckle clamping cylinder 306 to descend, and the positioning block 410 positions the clamping position. The buckle gripper 302 grips a single buckle under the action of the buckle clamping cylinder 306. Next, the buckle lifting assembly 305 rises, and the buckle lateral moving assembly 304 moves the buckle to directly above the clamping seat 203 of the feeding mechanism 2. After the buckle lifting assembly 305 descends again, the buckle gripper 302 releases, placing the buckle between the open clamping plates 205. Then, the clamping cylinder 206 resets, the push rod 208 descends, and the tension spring 204 pulls the clamping plates 205 to close, firmly clamping the buckle.

[0061] The clamping seat 203 continues to rotate with the rotating disk 202, reaching the fixed plate loading station. Simultaneously, the fixed plate loading mechanism 4 is activated, the fixed plate feeding disk 401 transports the fixed plate to the fixed plate positioning seat 402, and the fixed plate transfer cylinder 403 drives the transfer push plate 404 to push the fixed plate to the gripping position of the positioning seat. Subsequently, the fixed plate lateral movement assembly 406 moves the fixed plate lifting assembly 407 above this position, and the fixed plate lifting assembly 407 drives the fixed plate clamping cylinder 408 to descend. The fixed plate gripper 409, with the assistance of the positioning block 410, grips the fixed plate. Next, the fixed plate lifting assembly 407 rises, the fixed plate lateral movement assembly 406 moves the fixed plate directly above the retaining ring on the clamping seat 203, the fixed plate lifting assembly 407 descends, the fixed plate gripper 409 releases, and the fixed plate is precisely placed on the retaining ring.

[0062] The clamping seat 203 continues to rotate with the rotating disk 202 to the welding station. The clamping cylinder 508 on the welding support 507 drives the fixing plate to descend, further clamping and fixing the buckle to the fixing plate, so that the welding groove 510 on the fixing plate is just exposed at the part to be welded. At the same time, the lifting frame 503 on the welding bracket 501 adjusts the height of the welding device 506, and the welding translation cylinder 505 pushes the welding connecting frame 504 to slide along the lifting frame 503, so that the output end of the welding device 506 is aligned with the welding groove 510. Then, the welding device 506 starts and welds the contact part between the buckle and the fixing plate through the welding groove 510. After welding is completed, the clamping cylinder 508 resets, the fixing plate rises, and the clamping on the workpiece is released.

[0063] After welding, the workpiece rotates with the clamping seat 203 to the unloading station. The clamping cylinder 206 drives the push rod 208 again to lift the roller 207, and the clamping plate 205 opens. The unloading cylinder 602 of the unloading mechanism 6 is activated, driving the unloading pusher 603 to move, pushing the welded buckle and fixing plate from the clamping seat 203 to the guide groove 604. The workpiece slides down the guide groove 604 to the collection area. The unloading pusher 603 resets, the clamping cylinder 206 also resets, and the clamping plate 205 closes under the action of the tension spring 204, waiting for the next work cycle.

[0064] Throughout the process, the rotating disk 202 rotates continuously, and multiple clamping seats 203 participate in different processes simultaneously. When one clamping seat 203 is unloading, other clamping seats 203 may be performing welding, fixing plate loading, or buckle loading operations. The various mechanisms are seamlessly connected, realizing continuous automated production of buckle assembly.

[0065] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
