Description

Technical Field

[0001] This application relates to the technical field of fence mesh processing equipment, specifically a welding device. Background Technology

[0002] Currently, fencing systems are widely used in various sites such as industrial, road, agricultural, animal husbandry, power plant, and substation electrical equipment maintenance, electrical experiments, and power distribution maintenance as an important means of dividing space and blocking pedestrian flow, in order to ensure the safety of on-site personnel and equipment.

[0003] Existing fencing systems generally include fencing panels and fencing posts. The posts are positioned along the sides of the fencing panels to provide support. Existing fencing panels consist of an outer frame and a mesh surface. The outer frame includes horizontal and vertical guardrails; these guardrails are joined together to form a rectangular structure that surrounds the outside of the mesh surface to protect it. Additionally, to increase strength, at least one horizontal guardrail is typically installed between the two vertical guardrails on the outer frame.

[0004] In the existing technology, when processing fence panels, it is necessary to manually weld the horizontal and vertical guard edges together first, and then manually weld the mesh surface onto the horizontal and vertical guard edges. However, this processing method has the following drawbacks: (1) the workload of manual operation is large and the processing efficiency is low; (2) the degree of automation is low, and it requires close-range operation by humans, which can easily damage the operator's eyes and pose a safety hazard.

When the welding mechanism moves in the direction, the third fixing frame moves upward to lift the end of the outer frame near the welding mechanism until a longitudinal guard edge on the outer frame near the welding mechanism moves to the end of the second track body. At this point, the second clamping member separates from the longitudinal guard edge on the outer frame away from the welding mechanism, and the third clamping member separates from the longitudinal guard edge on the outer frame near the welding mechanism. This continues until the third clamping member moves with the third support frame and the third fixing frame to clamp the longitudinal guard edge on the outer frame away from the welding mechanism. Then, the outer frame moves with the third support frame towards the welding mechanism.

[0014] Preferably, the welding mechanism includes a second frame, a plurality of longitudinal welding components, and at least two transverse welding components. The second frame is located between the loading track and the unloading track.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: When using this welding device to weld and process fence mesh panels, it is only necessary to first place the outer frame on the feeding track, then place the mesh surface on the upper side of the outer frame, and use the positioning mechanism to achieve the positioning between the mesh surface and the outer frame, so as to ensure the welding accuracy between the mesh surface and the outer frame; then, the feeding mechanism drives the outer frame to move towards the welding mechanism. Since the positioning mechanism is set on the feeding mechanism, the positioning mechanism (i.e., the mesh surface) will also move synchronously with the outer frame while the outer frame moves, and the positioning between the mesh surface and the outer frame can always be guaranteed during the movement; finally, when the outer frame and the mesh surface pass the welding mechanism, the welding mechanism can automatically weld the mesh surface onto the outer frame until the outer frame and the mesh surface welded onto the outer frame move to the unloading track, and then the unloading mechanism pulls the outer frame (i.e., the outer frame and the mesh surface) away from the welding mechanism to achieve automatic unloading. The entire processing procedure described above is highly automated and efficient, which not only reduces the workload of manual operation and the demand for labor, but also avoids the need for close-range manual operation, thus preventing eye injuries to operators and enhancing safety. In addition, the welding device described above enables automatic welding between the mesh surface and the outer frame, providing a necessary foundation for the fully automated processing of fence panels.

Detailed Implementation

[0037] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] In the description of this application, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific scope of protection of this application.

The terms "comprising" and "having," and any variations thereof, in the specification and claims of this application, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0039] Reference Figure 1-16One embodiment of this application provides a welding device, including a feeding track 1, an unloading track 2, a welding mechanism 4, a feeding mechanism 5, an unloading mechanism 6, and a positioning mechanism 7; the welding mechanism 4 is located between the feeding track 1 and the unloading track 2; the feeding mechanism 5 is disposed on the feeding track 1, and the feeding mechanism 5 is used to pull the outer frame 100 on the feeding track 1 towards the direction closer to the welding mechanism 4; the positioning mechanism 7 is disposed on the feeding mechanism 5, and the positioning mechanism 7 is used to position the mesh surface 200 on the outer frame 100 so that the mesh surface 200 moves synchronously with the outer frame 100; when the outer frame 100 and the mesh surface 200 move to the unloading track 2 through the welding mechanism 4, the welding mechanism 4 is used to weld the mesh surface 200 to the outer frame 100; the unloading mechanism 6 is disposed on the unloading track 2, and the unloading mechanism 6 is used to pull the outer frame 100 on the unloading track 2 away from the welding mechanism 4. When processing the fence mesh panel, the outer frame 100 is first placed on the feeding track 1, and then the mesh panel 200 is placed on the upper side of the outer frame 100. The positioning mechanism 7 is used to position the mesh panel 200 and the outer frame 100 to ensure the welding accuracy between the mesh panel 200 and the outer frame 100. Then, the feeding mechanism 5 drives the outer frame 100 to move closer to the welding mechanism 4. During this process, since the positioning mechanism 7 is set in the feeding mechanism 5, the positioning mechanism 7 and the positioned mesh panel 200 will also follow the feeding mechanism 5 (i.e., the outer frame). 100) Synchronous movement ensures that the mesh surface 200 and the outer frame 100 are always positioned correctly during the movement. Finally, when the outer frame 100 and the mesh surface 200 pass the welding mechanism 4, the welding mechanism 4 automatically welds the mesh surface 200 onto the outer frame 100. This continues until the outer frame 100 and the mesh surface 200 welded to it move to the unloading track 2. Then, the unloading mechanism 6 pulls the outer frame 100 (i.e., the outer frame 100 and the mesh surface 200) away from the welding mechanism 4 to achieve automatic unloading. The entire processing process is highly automated and efficient, reducing manual workload and labor requirements. It also avoids close-range manual operation, thus preventing eye injuries and enhancing safety. Furthermore, this welding device enables automatic welding between the mesh surface 200 and the outer frame 100, providing a necessary foundation for fully automated processing of fence panels.

[0040] Reference Figure 1 , Figure 2 , Figure 5 as well as Figure 7In some embodiments of this application, the feeding track 1 includes a first track body 11 and a second track body 12 spaced apart, and a welding mechanism 4 is located between the second track body 12 and the unloading track 2; the welding device further includes a welding positioning mechanism 3, which is located between the first track body 11 and the second track body 12; the feeding mechanism 5 includes a first feeding component 51 and a second feeding component 52, which are respectively disposed on the first track body 11 and the second track body 12, and a positioning mechanism 7 is disposed on the first feeding component 51; when the first feeding component 51 is in use, the welding mechanism 4 is located between the second track body 12 and the unloading track 2. The material feeding component 51 pulls the outer frame 100 towards the welding positioning mechanism 3 until a longitudinal guard edge 101 on the outer frame 100 near the welding positioning mechanism 3 moves to the position of the welding positioning mechanism 3. The welding positioning mechanism 3 is used to weld and position the mesh surface 200 on the longitudinal guard edge 101. When the first feeding component 51 pulls the outer frame 100 past the welding positioning mechanism 3 to the second track body 12, the first feeding component 51 separates from the outer frame 100, the positioning mechanism 7 separates from the mesh surface 200, and the second feeding component 52 is used to pull the outer frame 100 towards the welding mechanism 4. During storage and transportation, multiple mesh surfaces 200 are usually stacked together to reduce the space occupied by the mesh surface 200. However, under the action of gravity, especially the lower mesh surface 200, it is very easy to deform, which can easily make the mesh surface 200 uneven. If this uneven mesh surface 200 is directly positioned on the outer frame 100 by the positioning mechanism 7 and then directly welded by the welding mechanism 4, the positioning mechanism 7 will restrict the displacement of the mesh surface 200 to limit the stress release on the mesh surface 200, resulting in an irregular mesh surface 200 after welding, which will affect sales.However, by setting a welding positioning mechanism 3 between the first track body 11 and the second track body 12, and by setting a first feeding component 51 on the first track body 11, the first feeding component 51 pulls the outer frame 100 along the first track body 11 towards the welding positioning mechanism 3; by setting the positioning mechanism 7 on the first feeding component 51, the positioning mechanism 7 and the mesh surface 200 can move synchronously with the first feeding component 51 (i.e., the outer frame 100) until a longitudinal guard edge 101 on the outer frame 100 near the welding positioning mechanism 3 moves to the position of the welding positioning mechanism 3, the welding positioning mechanism 3 will weld and position the mesh surface 200 on the longitudinal guard edge 101, so as to achieve The mesh surface 200 is rigidly positioned between itself and the outer frame 100. Then, the outer frame 100 is pushed onto the second track body 12 by the first feeding component 51, releasing the positioning mechanism 7 from the mesh surface 200. The second feeding component 52, located on the second track body 12, continues to pull the outer frame 100 (and the mesh surface 200 rigidly positioned on it) along the second track body 12 towards the welding mechanism 4. During welding by the welding mechanism 4, the positioning mechanism 7 does not restrict the movement of the mesh surface 200, allowing it to be in a free state. This facilitates the release of stress on the mesh surface 200, resulting in a more regular welded mesh surface 200. It should be noted that the welding positioning mechanism 3 only performs simple welding on the mesh surface 200, for example, welding only 1 to 3 points. In addition, in order to facilitate the movement of the outer frame 100, limit baffles 13 are provided on both sides of the first track body 11 and the second track body 12 to limit the movement of the outer frame 100 and the mesh surface 200, thereby improving the welding accuracy between the mesh surface 200 and the outer frame 100.

[0041] Reference Figure 5 as well as Figure 6In some embodiments of this application, the welding positioning mechanism 3 includes a first frame 31 and at least one welding positioning component 32, wherein the at least one welding positioning component 32 is longitudinally spaced on the first frame 31; each welding positioning component 32 includes an upper welding positioning block 321 and a lower welding positioning block 322, the lower welding positioning block 322 is fixed to the first frame 31, and the upper welding positioning block 321 is slidably disposed directly above the lower welding positioning block 322; when one of the outer frame 100 is close to the first frame 31 When the longitudinal guard edge 101 moves to directly above the lower welding positioning block 322, the upper welding positioning block 321 moves downward, forming a circuit between the upper welding positioning block 321, the mesh surface 200, the longitudinal guard edge 101, and the lower welding positioning block 322. A low-voltage, high-current direct current or alternating current is passed through this circuit, causing the contact surface between the mesh surface 200 (i.e., the transverse rib 202) and the outer frame 100 (i.e., the longitudinal guard edge 101) to heat up until it melts and fuses, thus welding and positioning the mesh surface 200 onto the longitudinal guard edge 101. Preferably, the lower welding positioning block 322 is connected to the negative electrode, and the upper welding positioning block 321 is preferably connected to the positive electrode. That is, before the upper welding positioning block 321 contacts the mesh surface 200, even if the lower welding positioning block 322 contacts the outer frame 100, the outer frame 100 and the mesh surface 200 will not be charged. In addition, it should be noted that this application does not limit the vertical sliding installation method of the upper welding positioning block 321. For example, the upper welding positioning block 321 can be directly driven to slide up and down by the drive cylinder 300 or the hydraulic cylinder.

[0042] Reference Figure 5 as well as Figure 6In some embodiments of this application, the welding positioning mechanism 3 further includes a first guide roller 33, a first guide frame 34, a first pressing roller 35, and a first pressing frame 36; the first guide roller 33 is arranged longitudinally between the first track body 11 and the lower welding positioning block 322, and the end of the first guide roller 33 is rotatably mounted on the first guide frame 34, which is slidably mounted on the first frame 31; when the outer frame 100 moves from the end of the first track body 11 toward the direction closer to the second track body 12, the first guide roller 35... 3 is used to lift the outer frame 100 upward to avoid the outer frame 100 contacting the lower welding positioning block 322; the first pressing roller 35 is arranged longitudinally above the first guide roller 33, and the end of the first pressing roller 35 is rotatably mounted on the first pressing frame 36, which is slidably mounted on the first frame 31; when the upper welding positioning block 321 moves downward, the first guide frame 34 and the first pressing frame 36 move downward, and the first pressing roller 35 is used to press the mesh surface 200 and the outer frame 100 onto the lower welding positioning block 322. In other words, in the initial state, the first guide roller 33 is located below the outer frame 100 of the first track body 11, and the first pressing roller 35 is located above the mesh surface 200 of the first track body 11, so that the outer frame 100 and the mesh surface 200 can enter the gap between the first guide roller 33 and the first pressing roller 35; when the outer frame 100 moves to directly above the first guide roller 33, the first guide frame 34 moves upward a certain distance, so that the first guide roller 33 pushes the outer frame 100 upward a certain distance, so that the outer frame 100 will not accidentally hit the lower welding positioning block 32 when it continues to move towards the second track body 12. 2. Enhanced safety and stability: When a longitudinal guard 101 on the outer frame 100 near the second track body 12 moves to directly above the lower welding positioning block 322, the first guide frame 34 and the first pressing frame 36 move downwards, allowing the first pressing roller 35 to press the mesh surface 200 and the outer frame 100 onto the lower welding positioning block 322, thus forming a stable loop between the upper welding positioning block 321, the mesh surface 200, the longitudinal guard 101, and the lower welding positioning block 322. In addition, the first pressing roller 35 can also initially flatten the mesh surface 200 to improve the welding accuracy and flatness of the mesh surface 200. Furthermore, since both the first guide roller 33 and the first pressing roller 35 can rotate, the movement resistance between the outer frame 100 and the first guide roller 33, as well as between the mesh surface 200 and the first pressing roller 35, can be sufficiently reduced. Moreover, during the movement of the outer frame 100 and the mesh surface 200 toward the second track body 12, the first pressing roller 35 is adapted to follow the first pressing frame 36 upward for a certain distance, thereby separating the first pressing roller 35 from the mesh surface 200, further reducing the movement resistance between the mesh surface 200 and the first pressing roller 35.It should be noted that this application does not limit the vertical sliding installation method of the first guide frame 34 and the first clamping frame 36. For example, the sliding limit is achieved by a sliding slider, and the drive cylinder 300 or hydraulic cylinder is used for driving.

[0043] Reference Figure 2 , Figure 3 as well as Figure 4 In some embodiments of this application, the first feeding assembly 51 includes a first support frame 511, a first fixing frame 512, and a first clamping member 513; the first support frame 511 is laterally slidably disposed below the first track body 11, and the first fixing frame 512 is vertically slidably disposed on the first support frame 511; the first clamping member 513 is disposed on the first fixing frame 512, and when the first clamping member 513 moves with the first support frame 511 and the first fixing frame 512 to clamp a longitudinal guard edge 101 on the outer frame 100 away from the first frame 31, the outer frame 100 can move with the first support frame 511 toward the direction of the welding positioning mechanism 3. In other words, by controlling the lateral sliding of the first support frame 511 and the vertical sliding of the first fixed frame 512, the position of the first clamping member 513 can be adjusted so that the first clamping member 513 can move to clamp the outer frame 100 to a longitudinal guard edge 101 away from the first frame 31, thereby allowing the outer frame 100 to move with the first support frame 511 towards the welding positioning mechanism 3. Alternatively, the first clamping member 513 can be controlled to move downwards to separate from the longitudinal guard edge 101, thus eliminating the interference between the first clamping member 513 and the outer frame 100, allowing the outer frame 100 and the mesh surface 200 to move completely onto the second track body 12. It should be noted that this application does not limit the lateral sliding installation method of the first support frame 511; for example, a sliding groove and slider can be used for sliding limit, and a lead screw can be used for driving. Furthermore, this application does not limit the vertical sliding installation method of the first fixed frame 512; for example, the first fixed frame 512 can be directly driven to slide up and down by a lifting cylinder 514. Furthermore, this application does not limit the specific structure of the first clamping member 513, for example, as Figure 3 and Figure 4 As shown, the first clamping member 513 includes a clamping cylinder 5131, a first clamping arm 5132, and a second clamping arm 5133. The first clamping arm 5132 has an L-shaped structure. One end of the first clamping arm 5132 is mounted on the first fixed frame 512, and the other end of the first clamping arm 5132 is arranged upward. The second clamping arm 5133 is horizontally slidably connected to the first clamping arm 5132. The clamping cylinder 5131 is mounted on the first fixed frame 512 or the first clamping arm 5132, and the clamping cylinder 5131 is used to drive the second clamping arm 5133 to slide horizontally, so that a clamping groove for clamping the longitudinal guard edge 101 is formed between the second clamping arm 5133 and the first clamping arm 5132.

[0044] Reference Figure 3 as well as Figure 4 In some embodiments of this application, the positioning mechanism 7 includes a positioning plate 71, which is fixed to the first fixing frame 512. The upper end of the positioning plate 71 is provided with a positioning slot 711. When the first clamping member 513 clamps the longitudinal guard edge 101, and at least one transverse rib 202 or at least one longitudinal rib 201 on the mesh surface 200 is accommodated in the positioning slot 711, positioning between the mesh surface 200 and the outer frame 100 is achieved. When the positioning plate 71 moves downward with the first fixing frame 512, the transverse rib 202 or the longitudinal rib 201 disengages from the positioning slot 711. Positioning between the mesh surface 200 and the outer frame 100 can be achieved through the positioning slot 711, and when the first fixing frame 512 moves downward, the mesh surface 200 can be separated from the positioning slot 711, making operation more convenient. The upper end of the positioning slot 711 is suitable for being chamfered or rounded, so that the transverse rib 202 or the longitudinal rib 201 can slide more easily into the positioning slot 711.

[0045] Reference Figure 7 as well as Figure 8In some embodiments of this application, the second feeding assembly 52 includes a second support frame 521, a second fixing frame 522, and a second clamping member 523; the second support frame 521 is laterally slidably disposed below the second track body 12, the second fixing frame 522 is vertically slidably disposed on the second support frame 521, and the second clamping member 523 is disposed on the second fixing frame 522; when a longitudinal guard edge 101 on the outer frame 100 near the welding mechanism 4 moves to the second track body 12, the second clamping member 523 follows the second support frame 521 and... The second fixing frame 522 moves to clamp a longitudinal guard 101 on the outer frame 100 near the welding mechanism 4, and the outer frame 100 moves away from the welding positioning mechanism 3 along with the second support frame 521. When the outer frame 100 moves completely onto the second track body 12, and the second clamping member 523 moves with the second fixing frame 522 and the second support frame 521 to clamp a longitudinal guard 101 on the outer frame 100 away from the welding mechanism 4, the outer frame 100 moves towards the welding mechanism 4 along with the second support frame 521. In other words, by controlling the lateral sliding of the second support frame 521 and the vertical sliding of the second fixed frame 522, the position of the second clamping member 523 can be adjusted, allowing the second clamping member 523 to move and clamp onto any longitudinal guard edge 101 on the outer frame 100, thereby enabling the outer frame 100 to move towards the welding positioning mechanism 3 along with the second support frame 521. Alternatively, the second clamping member 523 can be controlled to move downwards to separate from the longitudinal guard edge 101, thus eliminating the interference between the second clamping member 523 and the outer frame 100, allowing the outer frame 100 and the mesh surface 200 to move completely onto the unloading track 2. It should be noted that the lateral sliding installation method of the second support frame 521 can be the same as that of the first support frame, the vertical sliding installation method of the second fixed frame 522 can be the same as that of the first fixed frame 512, and the specific structure of the second clamping member 523 can be the same as that of the first clamping member 513.

[0046] Refer to 7 and Figure 8In some embodiments of this application, the second feeding assembly 52 further includes a third support frame 524, a third fixing frame 525, and a third clamping member 526. The third support frame 524 is laterally slidably disposed below the second track body 12, the third fixing frame 525 is vertically slidably disposed on the third support frame 524, and the third clamping member 526 is disposed on the third fixing frame 525. When the second clamping member 523 clamps a longitudinal guard edge 101 on the outer frame 100 away from the welding mechanism 4, the third clamping member 526 moves with the third support frame 524 and the third fixing frame 525 to clamp a longitudinal guard edge 101 on the outer frame 100 near the welding mechanism 4, so that the outer frame 100 can move synchronously with the second support frame 521 and the third support frame 524 towards the welding mechanism 4. When the outer frame 100 moves toward the welding mechanism 4, the third fixing frame 525 moves upward to lift the end of the outer frame 100 near the welding mechanism 4 until a longitudinal guard 101 on the outer frame 100 near the welding mechanism 4 moves to the end of the second track body 12. At this point, the second clamping member 523 separates from the longitudinal guard 101 on the outer frame 100 away from the welding mechanism 4, and the third clamping member 526 separates from the longitudinal guard 101 on the outer frame 100 near the welding mechanism 4. The outer frame 100 moves toward the welding mechanism 4 along with the third support frame 524 and the third fixing frame 525 to clamp the longitudinal guard 101 on the outer frame 100 away from the welding mechanism 4. In other words, when the outer frame 100 and the mesh surface 200 welded to the outer frame 100 move on the second track body 12, the second clamping member 523 clamps a longitudinal guarding edge 101 on the outer frame 100 away from the welding mechanism 4, the third clamping member 526 clamps a longitudinal guarding edge 101 on the outer frame 100 close to the welding mechanism 4, and the third fixing frame 525 moves upward a certain distance, so that the end of the outer frame 100 close to the welding mechanism 4 clamped by the third clamping member 526 moves upward a certain distance. This can reduce the sliding resistance of the outer frame 100 on the second track body 12 and reduce the wear between the outer frame 100 and the second track body 12. When the end of the outer frame 100 near the welding mechanism 4 moves to the end of the second track body 12, the second clamping member 523 and the third clamping member 526 separate from the two longitudinal guard edges 101 respectively, and the third clamping member 526 moves with the third fixing frame 525 and the third support frame 524 to clamp on a longitudinal guard edge 101 of the outer frame 100 away from the welding mechanism 4, so that the outer frame 100 and the mesh surface 200 can move with the third support frame 524 toward the direction of the welding mechanism 4; otherwise, if the outer frame 100 is driven to continue moving directly by the second clamping member 523, the third support frame 524, the third fixing frame 525 and the third clamping member 526 will interfere with the welding mechanism 4.It should be noted that the horizontal sliding installation method of the third support frame 524 can be the same as the horizontal sliding installation method of the first support, the vertical sliding installation method of the third fixing frame 525 can be the same as the vertical sliding installation method of the first fixing frame 512, and the specific structure of the third clamping member 526 can be the same as the specific structure of the first clamping member 513.

[0047] Reference Figure 9 as well as Figure 11In some embodiments of this application, the welding mechanism 4 includes a second frame 41, a plurality of longitudinal welding components 42, and at least two transverse welding components 43. The second frame 41 is located between the loading track 1 and the unloading track 2. The plurality of longitudinal welding components 42 are longitudinally spaced on the second frame 41, and at least two transverse welding components 43 are longitudinally spaced on the second frame 41, with the transverse welding components 43 located between the longitudinal welding components 42 and the unloading track 2. Each longitudinal welding component 42 includes an upper longitudinal welding block 421 and a lower longitudinal welding block 422. The lower longitudinal welding block 422 is fixed to the second frame 41, and the upper longitudinal welding block 421 is fixed to the lower longitudinal welding block 422. 1. It can be slidably set directly above the lower longitudinal welding block 422; when the longitudinal guard 101 on the outer frame 100 moves to directly above the lower longitudinal welding block 422, the upper longitudinal welding block 421 moves downward, so that a circuit is formed between the upper longitudinal welding block 421, the mesh surface 200, the longitudinal guard 101 and the lower longitudinal welding block 422. Low voltage high current DC or AC current is passed through the circuit, so that the contact surface between the mesh surface 200 (i.e., the transverse rib 202) and the outer frame 100 (i.e., the longitudinal guard 101) is heated to melt and fuse, so that the mesh surface 200 (i.e., the transverse rib 202) can be welded and fixed on the longitudinal guard 101. Each transverse welding assembly 43 includes an upper transverse welding block 431 and a lower transverse welding block 432. The lower transverse welding block 432 is fixed to the second frame 41, and the upper transverse welding block 431 is slidably positioned directly above the lower transverse welding block 432. When the transverse guard 102 on the outer shell moves to directly above the lower transverse welding block 432, the upper transverse welding block 431 moves downward, forming a circuit between the upper transverse welding block 431, the mesh surface 200, the transverse guard 102, and the lower transverse welding block 432. Low-voltage, high-current direct current or alternating current is passed through this circuit, causing the contact surface between the mesh surface 200 (i.e., longitudinal rib 201) and the outer frame 100 (i.e., transverse guard 102) to heat up until it melts and fuses, thereby welding and fixing the mesh surface 200 (i.e., longitudinal rib 201) onto the transverse guard 102. It should be noted that the lower longitudinal welding block 422 and the lower transverse welding block 432 are preferably connected to the negative electrode, and the upper longitudinal welding block 421 and the upper transverse welding block 431 are preferably connected to the positive electrode. That is, before the upper longitudinal welding block 421 (or the upper transverse welding block 431) contacts the mesh surface 200, even if the lower longitudinal welding block 422 (or the lower transverse welding block 432) contacts the outer frame 100, the outer frame 100 and the mesh surface 200 will not be charged. In addition, the upper longitudinal welding block 421 and the upper transverse welding block 431 are slidably installed in the same way as the upper welding positioning block 321.

[0048] Reference Figure 13In some embodiments of this application, when the longitudinal guard edge 101 on the outer frame 100 moves directly above the lower longitudinal welding block 422, the multiple upper longitudinal welding blocks 421 are welded sequentially from the middle to both sides at intervals. Specifically, when there is an odd number of upper longitudinal welding blocks 421, the middle upper longitudinal welding block 421 moves downward first (i.e., completes the welding operation first), followed by the two upper longitudinal welding blocks 421 adjacent to it on the left and right sides moving downward simultaneously (i.e., complete the welding operation simultaneously), and so on, with the multiple upper longitudinal welding blocks 421 being welded sequentially from the middle to both sides; similarly, when there is an even number of upper longitudinal welding blocks 421, the two middle upper longitudinal welding blocks 421 complete the welding first, followed by the two upper longitudinal welding blocks 421 adjacent to them on the left and right sides moving downward simultaneously, and so on, with the multiple upper longitudinal welding blocks 421 being welded sequentially from the middle to both sides. In other words, the transverse ribs 202 closer to the center of the mesh surface 200 are welded to the longitudinal guard edge 101 first. This way, even if the mesh surface 200 is not perfectly flat, this welding process can fully release the stress on the mesh surface 200, thus making it flatter. Its working principle is similar to waves, that is, pushing the mesh surface 200 flat from the center longitudinally to both sides. Figure 11-13 When the transverse guard 102 on the outer shell moves to directly above the lower transverse welding block 432, the multiple upper transverse welding blocks 431 are welded sequentially from both sides to the middle. After the end of the outer frame 100 near the welding mechanism 4 is completely welded to the mesh surface 200, the outer frame 100 and the mesh surface 200 continue to move towards the unloading track 2, and each transverse guard 102 moves to above each lower transverse welding block 432. At this time, each upper transverse welding block 431 is welded sequentially from both sides to the middle. Taking three as an example, the two outer upper transverse welding blocks 431 move downward first (i.e., complete the welding operation first), and the middle upper transverse welding block 431 moves downward later (i.e., completes the welding operation later), so that the welded mesh surface 200 is flatter. This is because the end of the mesh surface 200 near the welding mechanism 4 has been welded by multiple longitudinal... The welding assembly 42 is welded flat onto the outer frame 100. At this time, the two upper transverse welding blocks 431 on both sides move downwards simultaneously (i.e., the welding operation is completed simultaneously), so that the mesh surface 200 can be pushed flat away from the welding mechanism 4 on both sides along the longitudinal direction of the mesh surface 200. After the longitudinal sides of the mesh surface 200 are welded and fixed, the middle upper transverse welding block 431 completes the welding operation. Otherwise, if the middle upper transverse welding block 431 and the upper transverse welding blocks 431 on both sides complete the welding operation first, the mesh surface 200 is easily pressed off by the middle upper transverse welding block 431, so that the two ends of the longitudinal rib 201 cannot be aligned with the two outer transverse guard edges 102 at the same time.

[0049] Reference Figure 9 , Figure 10 as well as Figure 12In some embodiments of this application, the welding mechanism 4 further includes a second guide roller 44, a second guide frame 45, a second pressing roller 46, and a second pressing frame 47; the second guide roller 44 is arranged longitudinally between the feeding track 1 and the lower longitudinal welding block 422, and the end of the second guide roller 44 is rotatably mounted on the second guide frame 45, which is slidably mounted on the second frame 41; when the outer frame 100 moves from the end of the feeding track 1 toward the direction close to the unloading track 2, the second guide roller 44 is used to push the outer frame 100 upward to avoid The outer frame 100 is not in contact with the lower longitudinal welding block 422; the second pressing roller 46 is arranged longitudinally above the second guide roller 44, and the end of the second pressing roller 46 is rotatably mounted on the second pressing frame 47, which is slidably mounted on the second frame 41; when the upper longitudinal welding block 421 or the upper transverse welding block 431 moves downward, the second guide frame 45 and the second pressing frame 47 move downward, and the second pressing roller 46 is used to press the mesh surface 200 and the outer frame 100 onto the lower longitudinal welding block 422 or the lower transverse welding block 432. In other words, in the initial state, the second guide roller 44 is located below the outer frame 100 of the second track body 12, and the second pressing roller 46 is located above the mesh surface 200 of the second track body 12, so that the outer frame 100 and the mesh surface 200 can enter the gap between the second guide roller 44 and the second pressing roller 46; when the outer frame 100 moves to directly above the second guide roller 44, the second guide frame 45 moves upward a certain distance, so that the second guide roller 44 pushes the outer frame 100 upward a certain distance, so that when the outer frame 100 continues to move towards the unloading track 2, it will not accidentally hit the lower longitudinal welding block 422 and the lower transverse welding block 422. Welding block 432 provides higher safety and stability. When the longitudinal guarding edge 101 on the outer frame 100 moves above the lower longitudinal welding block 422 (or the transverse guarding edge 102 on the outer frame 100 moves above the lower transverse welding block 432), the second guide frame 45 and the second pressing frame 47 move downward, so that the second pressing roller 46 can press the mesh surface 200 and the outer frame 100 onto the lower longitudinal welding block 422 (or the lower transverse welding block 432), so that the circuit formed between them is more stable. In addition, the second pressing roller 46 can also initially flatten the mesh surface 200 to improve the welding accuracy and flatness of the mesh surface 200. Furthermore, since both the second guide roller 44 and the second pressing roller 46 can rotate, the movement resistance between the outer frame 100 and the second guide roller 44, as well as between the mesh surface 200 and the second pressing roller 46, can be sufficiently reduced. Moreover, during the movement of the outer frame 100 and the mesh surface 200 toward the unloading track 2, the second pressing roller 46 is adapted to follow the second pressing frame 47 upward for a certain distance, thereby separating the second pressing roller 46 from the mesh surface 200, further reducing the movement resistance between the mesh surface 200 and the second pressing roller 46.It should be noted that this application does not limit the vertical sliding installation method of the second guide frame 45 and the second clamping frame 47. For example, the sliding limit is achieved by a sliding slider, and the drive cylinder 300 or hydraulic cylinder is used for driving.

[0050] Reference Figure 14 as well as Figure 15 The unloading mechanism 6 includes an unloading support frame 61, an unloading fixing frame 62, and an unloading clamping member 63. The unloading support frame 61 is slidably disposed below the unloading track 2, and the unloading fixing frame 62 is slidably disposed on the unloading support frame 61. The unloading clamping member 63 is disposed on the unloading fixing frame 62. When a longitudinal guarding edge 101 on the outer frame 100 near the unloading track 2 moves to the unloading track 2, the unloading clamping member 63 moves with the unloading support frame 61 and the unloading fixing frame 62 to clamp the longitudinal guarding edge 101 on the outer frame 100 near the unloading track 2, and the outer frame 100 moves away from the welding mechanism 4 along with the unloading support frame 61. In other words, by controlling the lateral sliding of the unloading support frame 61 and the up-and-down sliding of the unloading fixing frame 62, the position of the unloading clamping member 63 can be adjusted so that the unloading clamping member 63 can move to clamp onto a longitudinal guarding edge 101 of the outer frame 100 near the unloading track 2, thereby allowing the outer frame 100 to move away from the welding mechanism 4 along with the unloading support frame 61 until unloading is completed. In addition, when welding the end of the mesh surface 200 that is off the unloading track 2 to the outer frame 100 by multiple longitudinal welding components 42, the outer frame 100 can also be clamped by the unloading clamping member 63, and the clamping effect of the third clamping member 526 on the outer frame 100 can be released to prevent mutual interference between the third clamping member 526 and the longitudinal welding components 42. It should be noted that the horizontal sliding installation method of the unloading support frame 61 can be the same as the horizontal sliding installation method of the first support frame 511, the vertical sliding installation method of the unloading fixing frame 62 can be the same as the vertical sliding installation method of the first fixing frame 512, and the specific structure of the unloading clamping member 63 can be the same as the specific structure of the first clamping member 513.

[0051] It should be noted that, as Figure 16As shown, when the upper longitudinal welding block 421 moves downward, it is suitable to apply a certain pressure to the end of the transverse rib 202 so that the transverse rib 202 is flattened after being heated and softened during welding, thereby forming a flat part 2021. This can improve the welding strength between the transverse rib 202 and the longitudinal guard edge 101, and also reduce the distance between the longitudinal rib 201 and the transverse guard edge 102, so as to improve the welding quality between the longitudinal rib 201 and the transverse guard edge 102. Furthermore, the presence of the transverse rib 202 creates a gap between the end of the longitudinal rib 201 and the transverse guard 102 (this gap is equal to the diameter of the transverse rib 202). When the upper transverse welding block 431 presses down on the longitudinal rib 201, the longitudinal rib 201 deforms, causing the end of the longitudinal rib 201 to contact the upper surface of the transverse guard 102, rather than the outer ring surface of the longitudinal rib 201 contacting the upper surface of the transverse guard 102. This can easily lead to weak welding between the longitudinal rib 201 and the transverse guard 102, and the longitudinal rib 201 may easily detach. Therefore, a gap can be created between the transverse guard 201 and the transverse guard 102. A groove 1021 is provided on the edge 102. When the upper transverse welding block 431 presses down on the longitudinal rib 201, the longitudinal rib 201 deforms and its outer ring surface can fully contact the inner wall of the groove 1021, thereby improving the welding strength between the longitudinal rib 201 and the transverse edge 102, making it less likely for the longitudinal rib 201 to fall off. At the same time, after the longitudinal rib 201 deforms, its end faces the inside of the groove 1021. That is, after welding and fixing, the end of the longitudinal rib 201 bends towards the inside of the groove 1021, which helps to protect the end of the longitudinal rib 201.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.

At this point, the second clamping member separates from the longitudinal guard edge on the outer frame away from the welding mechanism, and the third clamping member separates from the longitudinal guard edge on the outer frame near the welding mechanism. This continues until the third clamping member moves with the third support frame and the third fixing frame to clamp the longitudinal guard edge on the outer frame away from the welding mechanism. Then, the outer frame moves with the third support frame towards the welding mechanism.

8. The welding apparatus as claimed in claim 1, characterized in that, The welding mechanism includes a second frame, a plurality of longitudinal welding components, and at least two transverse welding components. The second frame is located between the loading track and the unloading track. The plurality of longitudinal welding components are arranged longitudinally at intervals on the second frame, and the at least two transverse welding components are arranged longitudinally at intervals on the second frame, with the transverse welding components located between the longitudinal welding components and the unloading track. Each of the longitudinal welding components includes an upper longitudinal welding block and a lower longitudinal welding block, the lower longitudinal welding block being fixed to the second frame, and the upper longitudinal welding block being slidably disposed directly above the lower longitudinal welding block; When the longitudinal guard edge on the outer frame moves to directly above the lower longitudinal welding block, the upper longitudinal welding block moves downward, so that a loop is formed between the upper longitudinal welding block, the mesh, the longitudinal guard edge, and the lower longitudinal welding block, so as to weld the mesh onto the longitudinal guard edge; Each of the transverse welding components includes an upper transverse welding block and a lower transverse welding block. The lower transverse welding block is fixed to the second frame, and the upper transverse welding block is slidably disposed directly above the lower transverse welding block. When the transverse guard on the outer frame moves to directly above the lower transverse welding block, the upper transverse welding block moves downward, so that a loop is formed between the upper transverse welding block, the mesh surface, the transverse guard, and the lower transverse welding block, so as to weld the mesh surface onto the transverse guard.

9. The welding apparatus as described in claim 8, characterized in that, The welding mechanism further includes a second guide roller, a second guide frame, a second clamping roller, and a second clamping frame; The second guide roller is arranged longitudinally between the feeding track and the lower longitudinal welding block. The end of the second guide roller is rotatably mounted on the second guide frame, and the second guide frame is slidably mounted on the second frame. When the outer frame moves from the end of the loading track toward the unloading track, the second guide roller is used to push the outer frame upward to avoid the outer frame contacting the lower longitudinal welding block; The second pressing roller is arranged longitudinally above the second guide roller, and the end of the second pressing roller is rotatably mounted on the second pressing frame. The second pressing frame is slidably mounted on the second frame. When the upper longitudinal welding block or the upper transverse welding block moves downward, the second guide frame and the second pressing frame move downward, and the second pressing roller is used to press the mesh surface and the outer frame onto the lower longitudinal welding block or the lower transverse welding block. The unloading mechanism includes an unloading support frame, an unloading fixing frame, and an unloading clamping component. The unloading support frame is laterally slidably disposed below the unloading track, and the unloading fixing frame is vertically slidably disposed on the unloading support frame. The unloading clamping component is disposed on the unloading fixing frame. When a longitudinal guard edge on the outer frame near the unloading track moves onto the unloading track, the unloading clamping component moves along with the unloading support frame and the unloading fixing frame to clamp the longitudinal guard edge on the outer frame near the unloading track, allowing the outer frame to move away from the welding mechanism along with the unloading support frame. When the longitudinal guard edge on the outer frame moves to directly above the lower longitudinal welding block, the multiple upper longitudinal welding blocks are welded sequentially and at intervals from the middle to both sides. When the horizontal guard edge on the outer frame moves to directly above the lower horizontal welding block, the multiple upper horizontal welding blocks are welded sequentially from both sides toward the middle at intervals.
