Description

Technical Field

[0001] This invention relates to the field of brazing furnace technology, and specifically to a production equipment and process for a brazing furnace operating zone. Background Technology

[0002] Generally speaking, the brazing furnace running belt is the core unit for continuous workpiece conveying in the brazing production line. As a key conveying carrier under heavy load and high temperature conditions, the structural stability of the chain mesh belt directly affects the continuity of the brazing process and the workpiece conveying accuracy.

[0003] Some brazing furnace mesh belts employ a composite structure of chain and mesh belt. The wire thread is not directly welded to the chain; instead, it is indirectly connected via an extension shaft of the chain pin. First, the extension shaft is fixedly connected to the chain pin, then the wire thread is wound around the extension shaft, and finally, the wire thread wound on the extension shaft is welded to prevent it from loosening. However, the winding and fixing of the wire thread to the pin and extension shaft relies entirely on manual operation, requiring hand-tightening to ensure the wire thread is tightly attached to the extension shaft. Furthermore, a single chain-type mesh belt can have dozens or even hundreds of wire thread and pin / extension shaft connections, which not only complicates assembly... The process is time-consuming and labor-intensive, significantly reducing the production efficiency of the mesh belt. Furthermore, due to the poor consistency of manual operation, the tightness of the wire threading and winding is uneven. If the winding is too loose, the wire threading may slip during high-temperature transmission. If the winding is too tight, the wire threading will generate pre-tension stress, which may cause brittleness at high temperatures. All of these leave structural hidden dangers for the operation of the mesh belt. In severe cases, it may lead to production accidents such as mesh belt breakage and workpiece falling. Based on this, the present invention purposefully provides a chain brazing furnace mesh belt production device and process that can simplify the connection structure between the wire threading and the chain pin extension shaft, replace the manual winding operation, and improve assembly consistency and efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a production equipment and process for the brazing furnace operating zone, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: A production device for a brazing furnace operating zone includes: The mesh belt has multiple equally spaced wires inside. First bases are located on both sides of the mesh belt, each corresponding to a top plate and a second base. A clamping assembly is located on the top of each first base, clamping and fixing four equally spaced extension rods. Each extension rod is coaxially arranged with a wire. A lifting frame is located on each top plate, with a sliding plate slidably mounted at the bottom of the lifting frame. The sliding plate is driven to move by a first driving source on the lifting frame. The sliding plate has four equally spaced through holes, each containing a rotating ring rotatably mounted. The rotating ring is driven to rotate by the driving assembly, and a contact block is located on the rotating ring. A U-shaped groove is formed at the end of the contact block facing the axis of the rotating ring. The four fixed seats are evenly spaced and fixedly installed on the top of the second base. Each fixed seat has two L-shaped rotating plates rotatably installed. When the two L-shaped rotating plates are combined, the threading is located inside the two L-shaped rotating plates, and the top of the threading abuts against the L-shaped rotating plates. The end of the threading is folded by the folding assembly and attached to the outer circular surface of the extension rod. When the driving assembly drives the translation plate to move toward the extension rod, the U-shaped groove on the abutment block is slidably connected with the threading attached to the extension rod, and the driving assembly drives the rotating ring to rotate at a constant speed.

[0006] As a further aspect of the present invention: two balls are rotatably mounted on one end of the abutment block facing the extension rod, and the two balls are symmetrically arranged about the U-shaped groove. When the U-shaped groove on the abutment block is slidably connected to the threaded wire attached to the extension rod, the balls abut against the outer surface of the extension rod.

[0007] As a further embodiment of the present invention: the drive assembly includes an external gear ring, a gear, a synchronous pulley, and a synchronous belt. One end of the rotating ring protrudes from the translation plate. The external gear ring is sleeved on the outer circumference of the rotating ring and is fixedly connected to the rotating ring. The gear is rotatably mounted on the translation plate and meshes with the external gear ring. Four synchronous pulleys are rotatably mounted on the translation plate, and each synchronous pulley is coaxially fixedly connected to a gear. Adjacent synchronous pulleys are connected by a synchronous belt, and one of the synchronous pulleys is driven to rotate by a power source.

[0008] As a further aspect of the present invention: the clamping assembly includes a lifting plate and a clamping plate. The lifting plate is slidably mounted on the top of the first base. The lifting plate is driven to rise and fall by a second driving source provided in the first base. Each extension rod has two corresponding clamping plates. Both clamping plates are slidably mounted on the top of the lifting plate. When the two clamping plates approach each other, they clamp and fix the extension rod.

[0009] As a further aspect of the present invention: the top of the fixed base has two symmetrically arranged notches, and the two L-shaped rotating plates are rotatably installed in the notches. Each L-shaped rotating plate is driven to rotate by the output source. When the two L-shaped rotating plates rotate away, the two L-shaped rotating plates retract into the notches.

[0010] As a further aspect of the present invention: the folding assembly includes a third base and a lifting rod. The third base is located between the second base and the first base. The lifting rod is slidably installed in the third base. The lifting rod is driven to rise and fall by a third drive source fixedly installed in the third base. When the two L-shaped rotating plates are combined, the third drive source drives the lifting rod to rise. At this time, the lifting rod will fold the thread upward. When the translation plate moves toward the extension rod, the abutment block abuts against the thread and folds the thread to fit against the outer circle surface of the extension rod.

[0011] As a further aspect of the present invention: each of the rotating rings is provided with a sliding groove, the abutting block is slidably installed in the sliding groove, and the abutting block is driven to rise and fall by a fourth driving source provided in the sliding groove, and the abutting block moves in the radial direction of the extension rod.

[0012] A production process for a brazing furnace running belt, the process being applied to a production equipment for a brazing furnace running belt as described above, the process comprising the following steps: Step S1: First, straighten the wire and control the output source to drive the L-shaped rotating plate to rotate away, ensuring that the wire can pass smoothly through the preset path in the through hole.

[0013] Step S2: Place the four equally spaced extension rods on the corresponding clamping components, ensuring that the extension rods are coaxially arranged with the wire threading, and then clamp and fix the extension rods using the clamping components.

[0014] Step S3: Fold the end of the threaded wire upward to a preset angle using the folding assembly, and start the first drive source to drive the translation plate to move toward the extension rod until the U-shaped groove on the abutment block forms a sliding connection with the pre-folded threaded wire. At this time, the threaded wire is attached to the outer circle surface of the extension rod.

[0015] Step S4: Drive the rotating ring to rotate at a constant speed through the drive component. The rotating ring drives the abutment block to rotate synchronously. During the rotation, the first drive source synchronously drives the translation plate to move toward the extension rod. Then the abutment block will gradually wrap the threaded wire around and tightly fit the outer circle surface of the extension rod, thus completing the operation of wrapping the end of the threaded wire around the outer circle surface of the extension rod.

[0016] Step S5: After the wire end is completely wrapped around the outer surface of the extension rod, it first contacts the clamping assembly to clamp the extension rod and moves away from the extension rod. Then, the first drive source drives the translation plate away from the extension rod to avoid blocking the extension rod from moving to the welding station.

[0017] The beneficial effects of this invention are: 1. In this invention, the external tensioning component straightens the threading wire, the clamping component fixes the extension rod and ensures that the two are coaxial, and the driving component drives the rotating ring to rotate at a constant speed and the translation plate to move stably, so as to realize the automated winding of the threading wire on the extension rod, replacing the manual operation of twisting each one. Four sets of threading wire and extension rod connection can be completed at one time, which greatly shortens the assembly time of dozens or even hundreds of connections of a single mesh belt and solves the problem of time-consuming and labor-intensive manual operation. At the same time, the uniform rotation of the rotating ring and the precise feeding of the translation plate ensure the uniform tightness of the threading wire winding, improving the production efficiency and structural stability of the mesh belt.

[0018] 2. In this invention, the clamping assembly drives the lifting plate to rise and fall through the second drive source. The position of the lifting plate can be adjusted according to the size of the extension rod and the wire threading height to adapt to extension rods of different specifications. The adjustable structure of the abutment block that rises and falls radially along the extension rod can accurately adjust the position and pressure of the abutment block according to the diameter of the extension rod and the wire threading thickness. At the same time, the drive assembly drives multiple components to move synchronously through a single power source, which simplifies the structure and reduces costs. Subsequent maintenance only needs to target the core transmission components, reducing maintenance difficulty and costs.

[0019] 3. In this invention, the L-shaped rotating plate is used to position the wire threading support during merging, providing support for the wire threading fold. The folding component folds the wire threading in stages to avoid excessive force and damage. After winding, the clamping component is released from fixation and avoids the extension rod's movement path. The translation plate moves away from the extension rod to prevent the components from blocking the transfer of the extension rod and the wire threading assembly to the welding station, ensuring a smooth production process and reducing the risk of production stagnation or product damage caused by component interference.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 As shown, the present invention is a production equipment for a brazing furnace operating zone, comprising: A mesh belt 1 has multiple equally spaced threaded wires 2 inside it. A first base 3 is provided on both sides of the mesh belt 1. Each first base 3 corresponds to a top plate 7 and a second base 18. A clamping assembly is provided on the top of each first base 3, clamping and fixing four equally spaced extension rods 6. Each extension rod 6 is coaxially arranged with one threaded wire 2. A lifting frame 8 is provided on each top plate 7. A translation plate 9 is slidably installed at the bottom of the lifting frame 8. The translation plate 9 is driven to move by a first driving source provided on the lifting frame 8. Four equally spaced through holes 10 are provided on the translation plate 9, and a rotating ring 11 is rotatably installed in each through hole 10. The rotating ring 11 is driven to rotate by a driving assembly. An abutment block 12 is provided on the rotating ring 11, and a U-shaped groove 13 is provided at one end of the abutment block 12 facing the axis of the rotating ring 11. The four fixed seats 15 are evenly spaced and fixedly installed on the top of the second base 18. Each fixed seat 15 has two L-shaped rotating plates 16 rotatably installed on it. When the two L-shaped rotating plates 16 are combined, the thread 2 is located inside the two L-shaped rotating plates 16, and the top of the thread 2 abuts against the L-shaped rotating plate 16. The end of the thread 2 is folded by the folding assembly and attached to the outer circular surface of the extension rod 6. When the driving assembly drives the translation plate 9 to move toward the extension rod 6, the U-shaped groove 13 on the abutment block 12 is slidably connected to the thread 2 attached to the extension rod 6, and the driving assembly drives the rotating ring 11 to rotate at a constant speed.

[0025] The mesh belt 1 is straightened at both ends by external tensioning components.

[0026] In one embodiment of this invention, it should be noted that the external tensioning assembly of the present invention includes clamping mechanisms at both ends and a driving mechanism that drives the two clamping mechanisms to move away from each other. The above-mentioned components are all prior art, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of the present invention. The first driving source can be an electric cylinder, an electric telescopic rod, or other components that can achieve linear reciprocating motion. This embodiment does not impose specific limitations on these components.

[0027] The working principle of this invention is as follows: When it is necessary to produce a brazing furnace running belt, the clamping mechanisms at both ends of the mesh belt 1 are first clamped by the external tensioning assembly to hold the wire thread 2. Then, the driving mechanism drives the two clamping mechanisms to move away from each other, straightening the wire thread 2 and preventing it from affecting the subsequent folding and bonding accuracy due to slack. Next, the output source is controlled to drive the L-shaped rotating plate 16 to rotate, so that the two L-shaped rotating plates 16 merge, placing the wire thread 2 within the two L-shaped rotating plates 16 with its top abutting against the L-shaped rotating plates 16. The L-shaped rotating plates 16 support and position the wire thread 2, preventing it from shifting during subsequent folding. Then, the clamping assembly clamps and fixes the extension rod 6, ensuring that the extension rod 6 and the wire thread 2 are coaxially arranged, providing a precise positioning basis for the wire thread 2 to fit the extension rod 6. After that, the folding assembly is activated to fold the end of the wire thread 2 upward to a preset angle. Then, the first driving source drives the translation plate 9 toward the extension rod 6. The movement allows the U-shaped groove 13 on the abutment block 12 to slide and connect with the pre-folded wire thread 2. Simultaneously, the drive assembly drives the rotating ring 11 to rotate at a uniform speed. The rotating ring 11 drives the abutment block 12 to rotate synchronously. With the rotation of the abutment block 12 and the movement of the translation plate 9, the wire thread 2 is gradually folded and tightly attached to the outer surface of the extension rod 6. In this way, through the coordinated action of the mechanical structure, the wire thread 2 is automatically wound on the extension rod 6, replacing the manual operation of winding each wire thread one by one. Dozens or even hundreds of sets of wire thread 2 can be connected to the extension rod 6 on a single mesh belt, and four sets of wire thread 2 can be wound on the extension rod 6 at a time. This batch operation greatly improves production efficiency. Moreover, the uniform rotation of the rotating ring 11 and the stable movement of the translation plate 9 can ensure that the winding tightness of the wire thread 2 is uniform, avoiding the problem of winding too loosely or too tightly due to different force and speed during manual operation, which facilitates subsequent welding.

[0028] like Figure 3 As shown, in a preferred embodiment of the present invention, the abutment block 12 is rotatably mounted with two balls 14 at one end facing the extension rod 6, and the two balls 14 are symmetrically arranged about the U-shaped groove 13. When the U-shaped groove 13 on the abutment block 12 is slidably connected with the thread 2 attached to the extension rod 6, the balls 14 abut against the outer surface of the extension rod 6.

[0029] In practical application, when the abutment block 12 is slidably connected to the thread 2 through the U-shaped groove 13 and drives the thread 2 to adhere to the extension rod 6, the two balls 14 will simultaneously abut against the outer surface of the extension rod 6. On the one hand, the balls 14 can limit the movement trajectory of the abutment block 12, preventing the abutment block 12 from deviating during rotation and causing positional deviation when the thread 2 adheres to the extension rod 6, thus ensuring the coaxiality of the thread 2 and the extension rod 6. On the other hand, the rolling contact between the balls 14 and the extension rod 6 can reduce the frictional resistance when the abutment block 12 moves and rotates, preventing damage to the outer surface of the extension rod 6 due to friction, while ensuring the smoothness of the movement of the abutment block 12, thereby improving the uniformity of the thread 2 adhering to the extension rod 6.

[0030] like Figures 1-4 As shown, in a preferred embodiment of the present invention, the drive assembly includes an external gear ring 19, a gear 20, a synchronous pulley 21, and a synchronous belt 22. One end of the rotating ring 11 protrudes from the translation plate 9. The external gear ring 19 is sleeved on the outer circumferential surface of the rotating ring 11 and is fixedly connected to the rotating ring 11. The gear 20 is rotatably mounted on the translation plate 9 and meshes with the external gear ring 19. Four synchronous pulleys 21 are rotatably mounted on the translation plate 9, and each synchronous pulley 21 is coaxially fixedly connected to a gear 20. Adjacent synchronous pulleys 21 are connected by a synchronous belt 22, and one of the synchronous pulleys 21 is driven to rotate by a power source.

[0031] In one embodiment, the power source may be a servo motor, a servo motor or other components, or other mechanisms capable of rotational motion. This embodiment does not impose any specific limitations on these components.

[0032] In practical application, when the rotating ring 11 needs to be driven to rotate, the power source is activated, which drives the synchronous wheel 21 connected to it to rotate. Since two adjacent synchronous wheels 21 are connected by a synchronous belt 22, the synchronous wheel 21 will drive the other three synchronous wheels 21 to rotate synchronously through the synchronous belt 22. Each synchronous wheel 21 is coaxially and fixedly connected to a gear 20. When the synchronous wheel 21 rotates, it will drive the gear 20 to rotate synchronously. The gear 20 meshes with the external gear ring 19, thereby driving the external gear ring 19 to rotate. The external gear ring 19 is fixedly connected to the rotating ring 11, and finally the four rotating rings 11 are rotated synchronously and uniformly. This driving method can ensure that the rotation speed and direction of the four rotating rings 11 are completely consistent, avoiding the inconsistency in the progress of the threading 2 and the extension rod 6 due to the different rotation speed of a single rotating ring 11. This ensures the consistency of the threading 2 on the four extension rods 6, improves the product accuracy of mass production, and simplifies the driving structure by driving multiple components with one power source, reducing equipment cost and maintenance difficulty.

[0033] like Figures 1-5As shown, in a preferred embodiment of the present invention, the clamping assembly includes a lifting plate 4 and a clamping plate 5. The lifting plate 4 is slidably mounted on the top of the first base 3. The lifting plate 4 is driven to lift by a second driving source provided in the first base 3. Each extension rod 6 has two corresponding clamping plates 5. Both clamping plates 5 are slidably mounted on the top of the lifting plate 4. When the two clamping plates 5 approach each other, they clamp and fix the extension rod 6.

[0034] In one embodiment, the second driving source can be an electric cylinder, an electric telescopic rod, or other mechanisms capable of lifting and lowering. The two clamping plates 5 are driven by a bidirectional lead screw assembly driven by a motor to move in opposite directions. The clamping plate 5 has a groove on the side facing the extension rod 6 that mates with the outer circular surface of the extension rod 6. This embodiment does not impose specific limitations on this aspect.

[0035] In practical application, this embodiment first adjusts the lifting plate 4 to a suitable height based on the height of the threading 2 and the size of the extension rod 6, using a second drive source. This ensures that the extension rod 6 and the threading 2 can be coaxially arranged. Then, the extension rod 6 is placed between two clamping plates 5, and the motor is started to drive the bidirectional lead screw assembly. The bidirectional lead screw assembly moves the two clamping plates 5 closer together. Since the clamping plates 5 have grooves on the side facing the extension rod 6 that mate with the outer surface of the extension rod 6, when the two clamping plates 5 approach each other to fit against the outer surface of the extension rod 6, the extension rod 6 can be effectively... The extension rod 6 is now stably clamped. This clamping method increases the contact area between the clamping plate 5 and the extension rod 6 by the cooperation of the groove with the outer circular surface of the extension rod 6, thereby improving the clamping stability and preventing the extension rod 6 from rotating or shifting during the wire threading 2 process. On the other hand, the bidirectional screw assembly drive can ensure the synchronous movement of the two clamping plates 5, ensuring that the center of the extension rod 6 is aligned with the center of the lifting plate 4, thereby ensuring the coaxiality of the extension rod 6 and the wire threading 2. At the same time, the lifting function of the lifting plate 4 allows the clamping assembly to adapt to extension rods 6 of different sizes, improving the versatility of the equipment. More importantly, after the end of the thread 2 is completely wrapped around the extension rod 6, the two clamps 5 are moved away from each other, that is, the two clamps 5 are moved away from the extension rod 6, thereby releasing the clamping and fixing of the extension rod 6. At this time, the extension rod 6 is wrapped and fixed by the thread 2. Then, the lifting plate 4 is lowered to move the clamps 5 below the extension rod 6, so as to avoid the clamps 5 blocking the movement path of the extension rod 6 when the mesh belt 1 moves forward.

[0036] like Figures 1-5As shown, in a preferred embodiment of the present invention, the top of the fixed base 15 has two symmetrically arranged notches 17, and two L-shaped rotating plates 16 are rotatably installed in the notches 17. Each L-shaped rotating plate 16 is driven to rotate by the output source. When the two L-shaped rotating plates 16 rotate away, the two L-shaped rotating plates 16 retract into the notches 17.

[0037] In one embodiment, the output source may be a servo motor, a servo motor or other components, or other mechanisms capable of rotational motion. This embodiment does not impose any specific limitations on these components.

[0038] In practical application, during the device initialization phase, the output source drives the two L-shaped rotating plates 16 to rotate away, causing them to retract into the notch 17. At this time, an open space is formed at the top of the fixing base 15, facilitating the smooth passage of the threaded wire 2 through the preset path and preventing the L-shaped rotating plates 16 from obstructing the laying of the threaded wire 2. After the threaded wire 2 is laid, the output source drives the two L-shaped rotating plates 16 to rotate out of the notch 17 and merge, so that the threaded wire 2 is located within the two L-shaped rotating plates 16 with its top abutting against the L-shaped rotating plates 16. The L-shaped rotating plates 16 then guide the threaded wire 2 through the space. The L-shaped rotating plate 16 provides support and provides obstruction for the subsequent folding process of the thread 2. Specifically, when the thread 2 is subjected to an upward force, the L-shaped rotating plate 16 can fold due to the obstruction. After the process of the thread 2 adhering to the extension rod 6 is completed, the two L-shaped rotating plates 16 are driven to rotate away and retract into the notch 17 again, so as to avoid the L-shaped rotating plates 16 from obstructing the removal of the extension rod 6 and the thread 2 assembly, and at the same time prepare for the next laying of the thread 2. The whole process is highly automated and does not require manual adjustment of the position of the L-shaped rotating plate 16, thus improving production efficiency.

[0039] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the folding assembly includes a third base 24 and a lifting rod 25. The third base 24 is located between the second base 18 and the first base 3. The lifting rod 25 is slidably installed in the third base 24. The lifting rod 25 is driven to rise and fall by a third drive source fixedly installed in the third base 24. When the two L-shaped rotating plates 16 are combined, the third drive source drives the lifting rod 25 to rise. At this time, the lifting rod 25 folds the thread 2 upward. When the translation plate 9 moves toward the extension rod 6, the abutment block 12 abuts against the thread 2 and folds the thread 2 to fit against the outer surface of the extension rod 6.

[0040] In one embodiment, the third driving source may be an electric cylinder, an electric telescopic rod, or other mechanisms capable of lifting and lowering. This embodiment does not impose any specific limitations on these components.

[0041] In practical application, after the two L-shaped rotating plates 16 combine to support and position the threading 2, the third drive source is activated. The third drive source drives the lifting rod 25 to rise within the third base 24. During the rise, the lifting rod 25 contacts the end of the threading 2 and folds it upward to a preset angle, completing the pre-folding of the threading 2. The pre-folding process reduces the folding resistance when the abutment block 12 drives the threading 2 to fit against the extension rod 6, preventing the threading 2 from wrinkling or breaking due to sudden excessive force. The folded thread 2 is easier to engage with the U-shaped groove 13 on the abutment block 12, ensuring that the abutment block 12 can smoothly drive the thread 2 to fit against the extension rod 6. When the translation plate 9 moves toward the extension rod 6, the abutment block 12 will further abut against the pre-folded thread 2, and under the rotation of the rotating ring 11, the thread 2 will be completely folded to fit against the outer circle of the extension rod 6. The cooperation between the lifting rod 25 and the abutment block 12 realizes the step-by-step folding process of the thread 2, improving the flatness and tightness of the thread 2 fitting against the extension rod 6.

[0042] like Figures 1-2 As shown, in a preferred embodiment of the present invention, each of the rotating rings 11 is provided with a sliding groove 23, the abutting block 12 is slidably installed in the sliding groove 23, and the abutting block 12 is driven to rise and fall by a fourth driving source provided in the sliding groove 23, and the abutting block 12 moves in the radial direction along the extension rod 6.

[0043] In one embodiment, the fourth driving source may be an electric cylinder, an electric telescopic rod, or other mechanisms capable of lifting and lowering. This embodiment does not impose any specific limitations on these components.

[0044] In practical application, according to the diameter of the extension rod 6 and the thickness of the thread 2, the fourth drive source drives the abutment block 12 to move up and down in the radial direction of the extension rod 6 within the slide groove 23, adjusting the distance between the abutment block 12 and the extension rod 6. When the diameter of the extension rod 6 is large, the abutment block 12 is driven to move closer to the extension rod 6, ensuring that the U-shaped groove 13 on the abutment block 12 can effectively contact the thread 2 and drive it to adhere to the extension rod 6. When the diameter of the extension rod 6 is small, the abutment block 12 is driven to move away from the extension rod 6, avoiding excessive force when the abutment block 12 and the extension rod 6 are too close, which would cause the thread 2 to adhere. This adjustable structure allows the abutment block 12 to adapt to extension rods 6 of different sizes, improving the versatility of the equipment. At the same time, the pressure of the abutment block 12 can be precisely adjusted according to the thickness of the thread 2, ensuring the tightness of the thread 2 adhering to the extension rod 6, and avoiding problems such as insufficient pressure causing the thread 2 to not adhere firmly to the extension rod 6, or excessive pressure causing damage to the thread 2. More importantly, when moving from the translation plate 9 to the extension rod 6, since the abutment block 12 can abut against the thread 2 and fold the thread 2 towards the extension rod 6, it is possible to gradually fold the thread 2 towards the extension rod 6 by first raising the abutment block 12 a certain distance and then gradually lowering it.

[0045] Please see Figures 1-5 As shown, the present invention provides a production process for a brazing furnace running belt. This process is applied to a production equipment for a brazing furnace running belt as described in the above embodiments. The process includes the following steps: Step S1: First, straighten the wire thread 2 and control the output source to drive the L-shaped rotating plate 16 to rotate away, ensuring that the wire thread 2 can pass smoothly through the preset path in the through hole 10.

[0046] Step S2: Place the four equally spaced extension rods 6 on the corresponding clamping components, so that the extension rods 6 and the wire threading 2 are coaxially arranged, and then clamp and fix the extension rods 6 by the clamping components.

[0047] Step S3: Fold the end of the thread 2 upward to a preset angle using the folding assembly, and start the first drive source to drive the translation plate 9 to move toward the extension rod 6 until the U-shaped groove 13 on the abutment block 12 forms a sliding connection with the pre-folded thread 2. At this time, the thread 2 is attached to the outer circle surface of the extension rod 6.

[0048] Step S4: Drive the rotating ring 11 to rotate at a constant speed through the drive component. The rotating ring 11 drives the abutment block 12 to rotate synchronously. During the rotation, the first drive source synchronously drives the translation plate 9 to move toward the extension rod 6. Then the abutment block 12 will gradually wrap the thread 2 and tightly fit it against the outer circle surface of the extension rod 6, thus completing the operation of wrapping the end of the thread 2 on the outer circle surface of the extension rod 6.

[0049] Step S5: After the end of the wire thread 2 is completely wrapped around the outer surface of the extension rod 6, it first contacts the clamping assembly to clamp the extension rod 6 and moves away from the extension rod 6. Then the first drive source drives the translation plate 9 away from the extension rod 6 to avoid blocking the extension rod 6 from moving to the welding station.

[0050] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
