Description

Technical Field

[0001] This utility model relates to the field of space frame welding technology, specifically to a feeding device for space frame welding and forming. Background Technology

[0002] A feeding device is a mechanical device used to automatically transport raw materials or semi-finished products to processing, assembly or testing stations. Its core objective is to improve production efficiency, reduce human intervention and ensure process stability. Through mechanical transmission, pneumatic control or intelligent systems, it realizes the continuous or intermittent transport of materials from storage units to processing equipment, reducing manual handling and operational errors.

[0003] The space frame is composed of multiple first metal bars arranged side-by-side at intervals along a first direction and multiple second metal bars arranged in an alternating pattern along a second direction. The metal bars are connected by welding. In the traditional space frame manufacturing process, in order to achieve automated material feeding, groups of first or second metal bars are usually stored in a storage base. The metal bars are then pushed layer by layer to a designated height by a lifting mechanism, and then picked up and transferred to the worktable by a robotic arm.

[0004] However, the above technologies still face the following technical challenges during implementation: A single feeding device for welding a space frame is typically only suitable for one automated welding machine. When dealing with automated welding machines operating in different directions, multiple feeding devices are required. Furthermore, the feeding process involves multi-device coordination and complex transfer steps, resulting in a time-consuming and inefficient process. This fails to meet the demands of high-efficiency production for space frame welding equipment and becomes a key bottleneck restricting overall capacity improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for space frame welding and forming. Through the coordinated cooperation of multiple sets of pushing components, it effectively solves the problem that a single space frame welding and forming feeding device is usually only applicable to a single automated welding equipment, as well as the problem of multiple equipment working together in the feeding process.

[0006] The objective of this utility model can be achieved through the following technical solutions: A feeding device for welding and forming a space frame includes a main frame fixedly installed on a production line, wherein a pushing component and a driving component are provided on the main frame; The main frame includes a frame body, and an upper frame is provided above the frame body. The upper frame includes a semi-circular frame, and multiple load-bearing components are provided on the semi-circular frame. Among the multiple load-bearing components, two load-bearing components with a phase difference of 180° form a group. The feeding assembly includes multiple reciprocating linear motion mechanisms, each of which is equipped with a pushing component, and the multiple reciprocating linear motion mechanisms are connected by connecting parts. A set of the bearing components and a pushing component work together to push the material.

[0007] As a further embodiment of this utility model: the bearing component includes a bearing plate, and a straight bearing groove is formed on the top surface of the bearing plate.

[0008] As a further embodiment of this utility model: the reciprocating linear motion mechanism is provided in two sets, and each set of the reciprocating linear motion mechanism includes a pusher plate. The pusher plate is provided with an eccentric disc and a limiting post. A straight groove is opened through the bottom surface of the pusher plate. The eccentric disc is squeezed against the limiting post, thereby driving the pusher plate to move.

[0009] As a further embodiment of this utility model: a fixed shaft is provided between the two eccentric disks in the two reciprocating linear motion mechanisms, the two eccentric disks are connected through the fixed shaft, and the fixed shaft passes through the straight groove.

[0010] As a further embodiment of this utility model: the pushing component includes push rods, which are symmetrically distributed on both sides of the push plate.

[0011] As a further embodiment of this utility model, it also includes a storage box, which is located above the support plate, and semi-circular openings are evenly provided on both sides of the storage box, and the semi-circular openings are adapted to the straight support groove. The storage bin is equipped with a vibration assembly, which includes a vibration motor. The vibration motor is located inside the storage bin, and the semi-circular opening is located on the bottom surface of both sides of the storage bin.

[0012] As a further embodiment of this utility model: the phase difference between the two eccentric disks is 90°, and the limiting post is fixedly disposed on both sides of the eccentric disk, with the limiting post located on both sides along the length direction of the straight groove.

[0013] As a further embodiment of this utility model: the semi-circular frame includes a left semi-circular frame and a right semi-circular frame, the left semi-circular frame and the right semi-circular frame are symmetrically distributed on both sides of the main frame, and a notch is provided between the two ends of the left semi-circular frame and the right semi-circular frame during installation.

[0014] As a further embodiment of this utility model: the left semi-circular frame has a left side groove, the right semi-circular frame has a right side groove, the left side groove and the right side groove are symmetrically distributed, and the phase difference between the left side groove and the notch is 90°.

[0015] As a further embodiment of this utility model: the semi-circular frame is distributed in two sets, and the two sets of semi-circular frames are staggered, with the bottom semi-circular frame and the top semi-circular frame having a phase difference of 90°.

[0016] The beneficial effects of this utility model are: This invention, through the coordinated action of multiple sets of pushing components, enables the wires in the bearing groove to be smoothly pushed into the welding disc from multiple different directions, such as... Figure 1 As shown, with the feeding device as the starting point, each arrow in the diagram represents a path in a production line. Thanks to this design, the feeding device of this invention can be adapted to multiple sets of automated welding equipment. This design not only significantly improves production efficiency but also substantially reduces production costs because one feeding device can serve multiple welding machines, effectively reducing equipment investment and maintenance costs.

[0017] Furthermore, traditional operating methods typically require multiple drive sources to control each pushing component individually, which not only increases equipment complexity but also raises maintenance costs and operational difficulty. However, by using a fixed-axis connection, multiple pushing components can operate synchronously, greatly simplifying the transfer process and improving operational efficiency. The collaborative operation between devices is also more efficient, thus significantly enhancing overall production capacity and operational accuracy. This method effectively simplifies the multi-device collaboration and complex transfer processes in traditional material feeding procedures, significantly shortening feeding time and greatly improving feeding efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-10 As shown, a feeding device for welding and forming a space frame includes a main frame 100, a storage box 200 above the main frame 100, a pushing assembly 300 inside the main frame 100 for pushing the wires on the main frame 100, and a driving assembly below the pushing assembly 300, located inside the main frame 100, for driving the pushing assembly 300 to move, the driving assembly including a drive motor 400.

[0023] During operation, the wire is placed inside the storage box 200. Due to gravity, the wire falls into the groove reserved on the main frame 100. The drive motor 400 is started, and the drive motor 400 drives the pusher assembly 300 to perform reciprocating translational motion. During the movement, the pusher assembly 300 pushes the wire in the groove on the main frame 100, allowing the wire to enter the welding tray. The welding tray moves and leads the wire into the next process.

[0024] like Figures 2-5As shown, the aforementioned main frame 100 includes a frame body 101 fixedly mounted on the production line. An upper frame is fixedly mounted on the top of the frame body 101. The upper frame includes two sets of semi-circular frames 103. Each semi-circular frame 103 includes a left semi-circular frame 1031 and a right semi-circular frame 1032. The left semi-circular frame 1031 and the right semi-circular frame 1032 are respectively fixedly connected to the frame body 101 and symmetrically distributed on both sides of the frame body 101. A left-side groove 1 is provided in the middle of the left semi-circular frame 1031. 033, a right-side groove 1034 is provided in the middle of the right semi-circular frame 1032, and the left-side groove 1033 and the right-side groove 1034 are symmetrically distributed; a notch 1035 is provided between the two ends of the left semi-circular frame 1031 and the right semi-circular frame 1032 during installation, and the phase difference between the notch 1035 and the left-side groove 1033 or the right-side groove 1034 is 90°. The two sets of semi-circular frames 103 are distributed vertically and staggered, and the phase difference between the bottom semi-circular frame 103 and the top semi-circular frame 103 is 90°.

[0025] Two sets of baffles 104 are provided between the left semi-circular frame 1031 and the right semi-circular frame 1032, and the two sets of baffles 104 are symmetrically distributed about the center line of the left semi-circular frame 1031 and the right semi-circular frame 1032. The baffles 104 are fan-shaped and include a straight edge and an arc edge. A limit strip 105 is provided at the top of the straight edge of the baffle 104.

[0026] Each of the left groove 1033 and right groove 1034 is fixedly equipped with a bearing assembly. The bearing assembly includes a bearing plate 102, on which multiple straight bearing grooves 1021 are evenly distributed. The length direction of the straight bearing grooves 1021 is parallel to the length direction of the bearing plate 102, and the straight bearing grooves 1021 are parallel to each other. The straight bearing grooves 1021 are used to support the iron wire falling from the storage box 200. During operation, the pushing assembly 300 performs a reciprocating translational motion to push away the iron wire falling from the straight bearing grooves 1021.

[0027] Two sets of semi-circular frames 103 are provided, and the two sets of semi-circular frames 103 are distributed vertically and perpendicular to each other. The phase difference between the two sets of semi-circular frames 103 is 90°. The bottom surface of one semi-circular frame 103 is fixedly connected to the top surface of the other semi-circular frame, and the centers of the two semi-circular frames 103 and the other semi-circular frame are on the same vertical line. The main frame 100 also includes a base plate 106, which is fixedly connected to the main frame 100. A drive motor 400 is mounted on the top surface of the base plate 106.

[0028] By setting up multiple sets of support plates 102, each support plate 102 is connected to a production line. The wire is placed on the support plate 102 and enters the welding tray of the corresponding production line from different directions. This effectively solves the problem that a single mesh frame welding and forming feeding device is usually only applicable to a single automated welding machine, improving production efficiency and significantly reducing production costs.

[0029] like Figures 6-8 As shown, the aforementioned pusher assembly 300 includes a reciprocating linear motion mechanism, which includes a pusher plate 301 slidably connected to the top surface of the baffle 104. A rectangular groove 306 is provided on the bottom surface of the pusher plate 301. The rectangular groove 306 extends through the entire pusher plate 301 along its length direction. The rectangular grooves 306 are symmetrically distributed along the centerline of the width direction of the pusher plate 301. Through the cooperation of the rectangular grooves 306 and the limiting strip 105, the pusher plate 301 is slidably connected to the upper end of the baffle 104. A straight slot 305 is provided at the center of the top surface of the pusher plate 301. A limiting post 303 is symmetrically distributed on both sides of the straight slot 305 along its length direction. The limiting post 303 is fixedly connected to the top surface of the pusher plate 301. An eccentric disc 304 is provided on the top surface of the pusher plate 301 and between the two limiting posts 303.

[0030] The pusher plate 301 has symmetrically distributed pushing components on both sides of its width direction. The pushing components include multiple pusher rods 302, which are evenly distributed on one side of the pusher plate 301. The length direction of the pusher rods 302 is parallel to the length direction of the pusher plate 301. The pusher rods 302 are arranged parallel to each other and are adapted to the linear bearing groove 1021.

[0031] The aforementioned pusher assembly 300 is provided in two sets, and the two sets of pusher assemblies 300 are distributed vertically and perpendicular to each other. The phase difference between the two sets of pusher assemblies 300 is 90°. A drive motor 400 is provided on the frame body 101. The output shaft of the drive motor 400 is connected to a fixed shaft 307. The fixed shaft 307 passes upward through two eccentric disks 304 and slides in the corresponding straight groove 305 during operation.

[0032] During operation, the drive motor 400 starts and drives the two eccentric discs 304 to rotate through the fixed shaft 307. The two eccentric discs 304 are pressed against the limiting post 303, which in turn drives the pusher plate 301 to move. The pusher plate 301 drives the pusher rod 302 to move. The pusher rod 302 is adapted to the linear bearing groove 1021, which converts the rotational motion of the drive motor 400 into the reciprocating motion of the pusher rod 302, thereby pushing away the iron wire in the linear bearing groove 1021.

[0033] By connecting the eccentric disks 304 in the feeding assembly 300 through a fixed shaft 307, multiple feeding assemblies 300 can be driven simultaneously by a single drive source. This effectively solves the complexity and cumbersomeness of multiple devices working together in the production process, simplifies the multi-device coordination and complex transfer links in the traditional feeding process, significantly shortens the feeding time, and greatly improves the feeding efficiency.

[0034] like Figures 9-10 As shown, the storage box 200 is fixedly mounted above the support plate 102. The storage box 200 includes a vibration assembly fixedly mounted on its side. The vibration assembly includes a vibration motor 201, which is used to prevent the wire from getting stuck during its descent, thus preventing the wire from falling smoothly into the linear support groove 1021. Semi-circular openings 202 are evenly distributed on both sides of the storage box 200. The semi-circular openings 202 and the linear support groove 1021 are matched to each other, forming a complete circle. During operation, the wire enters the welding pad through the circle formed by the semi-circular openings 202 and the linear support groove 1021.

[0035] The working principle of this utility model: During operation, the wire is placed inside the storage box 200, and the vibration motor 201 starts. Under the vibration of the vibration motor 201, the wire falls into the linear bearing groove 1021 due to gravity.

[0036] Then, the drive motor 400 is started. The drive motor 400 drives two eccentric discs 304 to rotate through the fixed shaft 307. The two eccentric discs 304 are pressed against the limiting post 303, which in turn drives the pusher plate 301 to move. The fixed shaft 307 slides inside the straight groove 305 on the pusher plate 301. The pusher plate 301 drives the pusher rod 302 to move. The pusher rod 302 is adapted to the straight bearing groove 1021, which converts the rotational motion of the drive motor 400 into the reciprocating motion of the pusher rod 302, thereby pushing the wire in the straight bearing groove 1021 and allowing the wire to enter the welding plate. The welding plate moves and leads the wire into the next process.
