A radiator pre-welding binding device

Abstract

A radiator pre-welding binding device, comprising a housing, and an upper wire mechanism, a wire distribution mechanism, a clamping mechanism, a supporting mechanism, a wire passing mechanism and a synchronization mechanism arranged in the housing. The clamping head of the rotating device in the wire distribution mechanism can move longitudinally between the rear end of the supporting mechanism and the wire passing mechanism. Before binding, the wire distribution mechanism is first retreated to the rear end of the supporting mechanism. After the radiator is placed on the supporting mechanism, the wire distribution mechanism can move to the wire passing mechanism position. The wire feeding device feeds the wire downward, and the wire passes through the upper connector, the hole in the wire passing mechanism and the lower connector in turn and then passes out. Then, the wire distribution mechanism moves backward, and the two clamping heads pull the wire to retreat to the rear end of the supporting mechanism from the upper and lower surfaces of the radiator, respectively. Then, the two clamping heads abut against the opposite sides to make the two ends of the wire merge together. Under the action of the rotating device, the two ends of the wire are wound together and the radiator is bound tightly. The automatic binding work of the radiator is realized, and the efficiency is greatly improved compared with manual binding.

Description

Technical Field

[0001] This invention relates to the field of automated binding equipment technology, specifically a binding equipment for radiators before welding. Background Technology

[0002] In the radiator manufacturing process, the core needs to be temporarily assembled before welding. However, the core is only temporarily fixed by two side fixing plates, which can easily cause slight displacement during welding. To prevent the welded core from shifting, the core is usually pre-tied with metal wire, such as iron wire, before welding. For example, patent CN202222614494.5, entitled "An Auxiliary Binding Device for an Automobile Radiator," discloses such a binding device. However, it is a manual binding method, where metal wire is manually pulled out and wrapped around the outer ring of the radiator, and then the wire is tightened by hand to secure the radiator before welding. Addressing the slowness of manual operation, especially the inefficiency of one person tightening only one wire at a time, the applicant has developed an automated radiator pre-welding binding device that automatically tightens the metal wire around the outer ring of the radiator, replacing manual tightening. Summary of the Invention

[0003] To address the technical problem in the above-mentioned background technology that when manually binding wires, one person can only twist one metal wire at a time, the present invention provides an automated pre-welding binding device for radiators.

[0004] The technical solution of this invention is as follows:

[0005] A pre-welding fastening device for a radiator includes a housing and a component disposed within the housing:

[0006] The wire feeding mechanism, located at the rear end of the housing, is capable of conveying the metal wire to the wire feeding mechanism;

[0007] Fabrication mechanism, including:

[0008] The first longitudinal moving support is horizontally slidably connected inside the housing;

[0009] The first transverse slide rail is fixed on the first longitudinal moving bracket, and multiple sets of first sliding seats are slidably connected thereon.

[0010] The first sliding seat is rotatably connected to a rotating device on the front side and to a power unit on the rear side;

[0011] The rotating device includes a rotating arm, a connecting head, and a clamping head. The rotating arm includes two arms, both of which are rotatably connected to the first sliding seat. The connecting head is fixed at the end of the arm away from the first sliding seat. The clamping head is movably connected to the connecting head through a connecting rod. The connecting rod near the rotating arm is provided with a sliding groove and is movably connected to a pull rod. The pull rod passes through the rotating arm and is connected to the drive unit. Under the action of the drive unit, the pull rod can pull the connecting rod and the clamping head to rotate, and cause the two clamping heads connected to the two rotating arms to abut or separate on opposite sides. The minimum distance between the two connecting heads is greater than the thickness of the heat sink, and the initial position of the two connecting heads is one above the other arranged opposite each other.

[0012] The wire cutting device includes a wire cutting arm and a wire cutting head. The wire cutting arm is positioned above the rotating device, with its rear end fixed on a first longitudinal moving bracket and its front end provided with a wire cutting head.

[0013] The wire feeding device is fixed on the wire cutting arm or the first longitudinal moving bracket. It can convey the metal wire from the wire feeding mechanism downward. The clamping head has a hole at the front. The hole can be moved to the lower part of the metal wire conveying path of the wire feeding device under the push of the connecting rod. The wire cutting head is located on the metal wire conveying path of the wire feeding device.

[0014] The support mechanism is designed to support the radiator to be secured.

[0015] The clamping mechanism can clamp the radiator;

[0016] The wire threading mechanism is located at the front end of the housing. It has a through hole along the vertical direction to allow the metal wire to pass through. There is a connecting channel between the through hole and the outer wall of the wire threading mechanism. The metal wire can pass through the through hole and the connecting channel and abut against the heat sink under the pull of the clamping head.

[0017] The clamping head of the rotating device can move longitudinally between the rear end of the support mechanism and the wire threading mechanism. Before binding the wire, it first moves to the rear end of the support mechanism. After the radiator is placed on the support mechanism, it can move to the position of the wire threading mechanism. The wire feeding device feeds the wire downward. The metal wire passes through the upper connector, the through hole in the wire threading mechanism, and the lower connector in sequence before exiting.

[0018] Furthermore, the number of wire-laying mechanisms includes multiple mechanisms, each capable of winding one metal wire. Depending on the number of metal wires required to bind the radiator, after placing the radiator on the support mechanism, a corresponding number of wire-laying mechanisms can be set to simultaneously bind multiple metal wires. Moreover, this equipment can simultaneously bind multiple radiators, provided the housing width is designed wide enough to accommodate multiple support mechanisms for multiple radiators, and multiple wire-laying mechanisms can then be arranged.

[0019] The first sliding seat, support mechanism, clamping mechanism, and threading mechanism are all equipped with adjusting devices, which can move laterally on the corresponding slide rails to adjust their corresponding positions. Preferably, since the positions of the wire feeding mechanism, support mechanism, clamping mechanism, and threading mechanism for winding a single metal wire need to be relatively fixed, this application sets the first sliding seat, support mechanism, clamping mechanism, and threading mechanism to move synchronously laterally through adjusting devices to ensure the fixation of their relative positions.

[0020] Furthermore, regarding the design of the rotating device, the two rotating arms of the rotating device are fixed on the disc at the end away from the connector. The disc is rotatably connected to the first sliding seat, which is equipped with a power transmission device. The disc is connected to the power unit through the power transmission device, so that the two rotating arms and the connector and clamping head connected to them can rotate together around the center of the disc. When the two clamping heads collide on opposite sides, the two ends of the metal wire can be tightened together.

[0021] Specifically, regarding the design of the connector, the connector has a first mounting port that extends through both sides of the rotating arm on the side facing the rotating arm, and a working port that is parallel to the side of the rotating arm on the side away from the rotating arm. The connecting rod rotates in the working port, and the connecting rod on the side closer to the rotating arm can rotate into the first mounting port to facilitate the connection between the two.

[0022] Furthermore, in each rotating device, two connecting heads are symmetrically arranged relative to the center of the disk. The end of the connecting head away from the center of the disk is the upper working surface, and the end closer to the center of the disk is the lower working surface. The end of the connecting head away from the disk is provided with a working inclined surface. The connecting rod can pull the clamping head to rotate between the working inclined surface and the upper working surface, thereby realizing the contact or separation of the two clamping heads on opposite sides.

[0023] Preferably, each connector has two connecting rods. The side of the connector near the lower working surface has two first pin holes that penetrate both sides. One end of each connecting rod is rotatably connected to the shaft in the first pin hole, and the other end is rotatably connected to the clamping head. The two connecting rods are arranged in parallel. The two connecting rods, together with the connector and the clamping head, form a planar hinge four-bar mechanism. This structure is beneficial to the parallel and stable rotation of the clamping head.

[0024] Regarding the design of the clamping head, a second mounting port is provided at the end of the clamping head facing the connector. Second pin holes are provided on both sides of the second mounting port. The connecting rod is installed in the second mounting port through the pin. The minimum distance between the end of the second mounting port away from the connector and the adjacent connecting rod is greater than the diameter of the metal wire, so that the metal wire in the wire feeding device can pass smoothly through the clamping head.

[0025] Furthermore, the end of the clamping head away from the connecting head is a tapered head. The wire threading mechanism includes a fixed clamp and a movable clamp. The movable clamp is connected to a power unit. The upper and lower parts of the rearward ends of the fixed clamp and the movable clamp can form a Y-shaped groove for clamping the tapered head. The bottom of the Y-shaped groove has a through hole along the vertical direction.

[0026] Regarding the design of the clamping mechanism, it includes a second transverse slide rail, on which a second sliding seat is slidably connected to the front side. A telescopic cylinder is fixed to the front side of the second sliding seat, and a clamping element is connected to one end of the push rod of the telescopic cylinder. After the radiator is placed on the support mechanism, the clamping element can be moved forward or backward by controlling the movement of the telescopic cylinder, thereby clamping or releasing the radiator.

[0027] This application also provides a method for securing a radiator before soldering, which specifically includes the following steps:

[0028] S1. Move the fabric weaving mechanism to the rear end of the clamping mechanism;

[0029] S2. Place the radiator on the support mechanism;

[0030] S3. Start the clamping mechanism to clamp the radiator;

[0031] S4. Drive the pull rod to move, so that the two oppositely arranged clamping heads in the rotating device are separated to a distance greater than the thickness of the heat sink, and then drive the yarn feeding mechanism to move forward. The two oppositely arranged clamping heads in the rotating device move from above and below the heat sink to the upper and lower ends of the yarn feeding mechanism, respectively.

[0032] S5. Start the wire feeding mechanism to allow the metal wire to enter the wire feeding device, and then pass through the hole at the front of the upper clamping head, the vertical hole on the wire feeding mechanism, and the hole at the front of the lower clamping head in sequence, and continue to feed a metal wire with a length greater than the length of the heat sink.

[0033] S6. Drive the wire feeding mechanism to move backward, while the wire feeding mechanism continues to feed wire. The two opposing clamping heads in the rotating device simultaneously pull the metal wire backward, thereby pulling the metal wire up and down above and below the radiator at the same time, until the clamping heads move behind the clamping mechanism and stop the movement of the wire feeding mechanism.

[0034] S7. The wire-cutting head of the drive wire-cutting device cuts the metal wire, and the drive lever brings the two oppositely arranged clamping heads into contact.

[0035] S8. Drive the rotating device to rotate a preset number of revolutions;

[0036] S9. Drive the lever to separate the two oppositely arranged clamping heads and remove the bundled radiator.

[0037] The beneficial effects of this invention are as follows:

[0038] Through the above design, the pre-welding binding device for the radiator of the present invention has a clamping head of the rotating device that can move longitudinally between the rear end of the support mechanism and the wire threading mechanism. Before binding the wire, it first moves back to the rear end of the support mechanism. After the radiator is placed on the support mechanism, it can move to the position of the wire threading mechanism. The wire feeding device feeds the wire downward. The metal wire passes through the upper connector, the through hole in the wire threading mechanism, and the lower connector in sequence and then comes out. Then, the wire feeding mechanism moves backward. The two clamping heads pull the metal wire and move back from the upper and lower sides of the radiator to the rear end of the support mechanism. Then, the two clamping heads abut against each other on opposite sides, so that the two ends of the metal wire are joined together. Under the action of the rotating device, the two ends of the metal wire are wrapped together and the radiator is bound tightly.

[0039] Moreover, multiple wire-laying mechanisms can be set, each of which can be used to wrap one metal wire. Depending on the number of metal wires that need to be bound to the radiator, after the radiator is placed on the support mechanism, a corresponding number of wire-laying mechanisms can be set to bind multiple metal wires at the same time, so as to further improve work efficiency and greatly save the time of manually tightening the radiator.

[0056] See Figures 1-3 This embodiment provides a pre-welding binding device for a radiator, including a housing 1, and a wire feeding mechanism 2, a wire laying mechanism 3, a clamping mechanism 4, a supporting mechanism 5, a wire threading mechanism 6, and a synchronization mechanism 7 disposed within the housing 1. Among these,

[0057] The wire feeding mechanism 2 is located at the rear end of the housing 1 and can transport the metal wire to the wire feeding mechanism 3;

[0058] Fabric weaving mechanism 3 includes:

[0059] The first longitudinal moving support 31 is horizontally slidably connected inside the housing 1;

[0060] The first transverse slide rail 32 is fixed on the first longitudinal moving bracket 31, and multiple sets of first sliding seats 33 are slidably connected thereto.

[0061] The first sliding seat 33 is rotatably connected to the rotating device 35 on the front side and to the power unit on the rear side;

[0062] The rotating device 35 includes a rotating arm 351, a connector 352, and a clamping head 353. The rotating arm 351 includes two arms, both of which are rotatably connected to the first sliding seat 33. The connector 352 is fixed at the end of the arm away from the first sliding seat 33. The connector 352 is movably connected to the clamping head 353 through a connecting rod. The connecting rod near the rotating arm 351 is provided with a sliding groove and is movably connected to a pull rod. The pull rod passes through the rotating arm 351 and is connected to the drive unit. Under the action of the drive unit, the pull rod can pull the connecting rod and the clamping head 353 to rotate, and cause the two clamping heads 353 connected to the two rotating arms 351 to abut or separate on opposite sides. The minimum distance between the two connectors 352 is greater than the thickness of the heat sink, and the initial position of the two connectors 352 is arranged opposite to each other, one above the other.

[0063] The wire cutting device 36 includes a wire cutting arm 361 and a wire cutting head 362. The wire cutting arm 361 is positioned above the rotating device 35, with its rear end fixed on the first longitudinal moving bracket 31 and its front end provided with the wire cutting head 362.

[0064] The wire feeding device 37 is fixed on the wire cutting arm 361 or the first longitudinal moving bracket 31, and can convey the metal wire from the wire feeding mechanism 2 downward. The clamping head 353 has a hole at the front, which can be moved to the lower part of the metal wire conveying path of the wire feeding device 37 under the push of the connecting rod. The wire cutting head 362 is located on the metal wire conveying path of the wire feeding device 37.

[0065] Support mechanism 5 is capable of supporting the radiator to be tightened;

[0066] Clamping mechanism 4 is capable of clamping the radiator;

[0067] The wire threading mechanism 6 is arranged at the front end of the housing 1. It has a through hole along the vertical direction to accommodate the metal wire. There is a connecting channel between the through hole and the outer wall. The metal wire can pass through the through hole and the connecting channel and abut against the heat sink under the pull of the clamping head.

[0068] The synchronization mechanism 7 includes a distance adjustment device installed on the first sliding seat 33, the support mechanism 5, the clamping mechanism 4 and the threading mechanism 6. All distance adjustment devices are set to operate synchronously and can move laterally on the corresponding slide rails to adjust the corresponding positions.

[0069] Through the coordinated action of the aforementioned mechanisms, the clamping head 353 of the rotating device 35 can move longitudinally between the rear end of the support mechanism 5 and the threading mechanism 6. Before binding the wire, it first retracts to the rear end of the support mechanism 5. After the radiator is placed on the support mechanism 5, it can move to the position of the threading mechanism 6. The wire feeding device 37 feeds the wire downward, and the metal wire passes through the upper connector 352, the through hole in the threading mechanism 6, and the lower connector 352 in sequence before exiting. After passing through a sufficient length, the wire feeding mechanism 3 moves backward, and the two clamping heads 353 pull the metal wire from the upper and lower sides of the radiator and retract to the rear end of the support mechanism 5 respectively. Then, the two clamping heads 353 abut against each other on opposite sides, causing the two ends of the metal wire to merge together. Under the action of the rotating device 35, the two ends of the metal wire are wrapped together and tightly bound to the radiator.

[0070] The above describes the binding process for a single metal wire. In practical applications, the radiator needs to be bound with two or three metal wires. Therefore, there are multiple wire-laying mechanisms 3, each capable of winding one metal wire. Depending on the number of metal wires required to bind the radiator, after placing the radiator on the support mechanism 5, a corresponding number of wire-laying mechanisms 3 can be set to bind multiple metal wires simultaneously. Moreover, this device can also perform the simultaneous binding of multiple radiators, provided that the width of the housing 1 is designed to be wide enough to accommodate multiple support mechanisms 5 to hold multiple radiators, and multiple wire-laying mechanisms 3 can be arranged at the same time.

[0071] The specific structure of each institution will be described below with reference to the accompanying diagrams.

[0072] See Figure 1 The housing 1 includes a lower chamber 11 and an upper cover 12. The upper cover 12 covers the rear of the lower chamber 11, and the width of the lower chamber 11 is sufficient to accommodate multiple weaving mechanisms 3 arranged side by side. The front end of the upper cover 12 is provided with a vertical baffle 121, and a wire-passing hole 122 is opened on the upper part of the baffle 121 for the metal wire to pass through. In this embodiment, iron wire is used as an example of the metal wire.

[0073] See Figure 2 The wire feeding mechanism 2 is located at the rear end of the housing 1 and includes a wire roll 21 and a wire drawing device 22. The wire roll 21 is located at the lower rear of the lower compartment 11, and the wire drawing device 22 is located at the upper rear of the upper cover 12. It controls the wire drawing action and is used to draw the wire in the wire roll 21 upward into the guide hose. The guide hose is connected to the wire feeding device 37 through the wire hole 122 on the baffle 121.

[0074] See appendix Figure 2-5The first longitudinal moving bracket 31 in the fabrication mechanism 3 includes a lower bracket 311, an upper bracket 312 and a vertical bracket 313. The lower bracket 311 is horizontally slidably connected to the slide rails on both sides of the inner wall of the housing 1, and its rear part is vertically connected to the vertical bracket 313. The top of the vertical bracket 313 is connected to the forward-extending upper bracket 312, which can be used to fix various lines.

[0075] Furthermore, a first transverse slide rail 32 is fixed to the upper rear surface of the lower bracket 311, and multiple sets of first sliding seats 33 are slidably connected to it. A scissor-type connecting frame is transversely connected below the multiple sets of first sliding seats 33. By controlling the extension and retraction distance of the scissor-type connecting frame, the relative distance between the multiple sets of first sliding seats 33 can be controlled, thereby allowing the fabrication mechanism 3 to adapt to heat sinks of different sizes.

[0076] Furthermore, the rear end of the rotating device 35 is rotatably connected to the first sliding seat 33, and its power comes from the motor 34 mounted on the first longitudinal moving bracket 31. Specifically, a fixed seat is provided at the rear end of the first sliding seat 33, on which a rotating shaft is rotatably connected via a bearing. The rotating shaft is arranged laterally, and its outer wall has several grooves along its axial direction. A first bevel gear is slidably connected in the grooves, and the large end of the first bevel gear is fixedly connected to the bearing. A second bevel gear is connected to the first sliding seat 33, and the second bevel gear meshes with the first bevel gear. The second bevel gear is connected to the rotating device 35 via an intermediate power transmission device, such as a gear drive. The motor 34 is connected to the rotating shaft via the power transmission device.

[0077] In the early stage, when the position of the first sliding seat 33 is adjusted by the scissor-type connecting frame, the multiple first sliding seats 33 are connected to the first bevel gear and move laterally along the axis of the rotating shaft. In the later stage, when the rotating device 35 needs to be rotated, the rotating shaft is driven to rotate by the motor 34, the first bevel gear rotates with the rotating shaft, and drives the second bevel gear to rotate, and then drives the rotating device 35 to rotate through the intermediate power transmission device.

[0078] The following is combined with Figure 4 The design of the rotating device 35 is described below. The two rotating arms 351 of the rotating device 35 are fixed on the disk at the ends away from the connector 352. The disk is rotatably connected to the first sliding seat 33 and is driven to rotate by the motor 34. This allows the two rotating arms 351, the connector 352 and the clamping head 353 connected to them to rotate together around the center of the disk.

[0079] Furthermore, the two rotating arms 351 are arranged symmetrically relative to the center of the disk. The interior of the rotating arms 351 is hollow and contains a pull rod. A power unit is fixed inside the disk and connected to the pull rod, which can control the extension and retraction of the pull rod.

[0080] The following is combined with Figure 9 , Figure 9The connector 352 is designed as a single square piece of material, with a portion of the material milled off from each of its opposite sides. The connector 352 has a first mounting opening 3521 extending through both sides of the rotating arm 351 on the side facing it, and a working opening 3522 parallel to its side on the side away from the rotating arm 351. The connecting rod rotates within the working opening 3522, and the connecting rod closer to the rotating arm 351 can rotate into the first mounting opening 3521, facilitating the movable connection of the rear connecting rod and the pull rod.

[0081] Furthermore, in each rotating device 35, two connectors 352 are symmetrically arranged relative to the center of the disk. The end of the connector 352 furthest from the center of the disk is the upper working surface 3523, and the end closer to the center of the disk is the lower working surface, with the upper and lower working surfaces arranged in parallel. A working inclined surface 3524 is provided at the end of the connector 352 furthest from the disk. The connecting rod can pull the clamping head 353 to rotate between the working inclined surface 3524 and the upper working surface 3523, thereby achieving contact or separation of the two clamping heads 353 on opposite sides. When the two clamping heads 353 are in contact on opposite sides, the two ends of the metal wire can be clamped and tightened together by the rotating device.

[0082] In this embodiment, the rotation mechanism of the clamping head 353 is designed as a planar hinged four-bar linkage. Specifically, each connector 352 has two connecting rods. The side of the connector 352 near the lower working surface has two first pin holes 3525 that penetrate both sides. One end of each connecting rod is rotatably connected to the rotating shaft in the first pin hole 3525, and the other end is rotatably connected to the clamping head 353. The two connecting rods are arranged in parallel, so that the two connecting rods, the connector 352, and the clamping head 353 together form a planar hinged four-bar linkage. This structure is beneficial to the parallel and stable rotation of the clamping head 353.

[0083] Furthermore, a limit bolt 3526 is threadedly connected to the rear of the upper working surface 3523 of the connector 352. By adjusting the length of the bolt extending into the working port 3522, the clamping head 353 can be rotated to a position above the upper working surface 3523. This ensures that when the two clamping heads 353 are in contact with each other, the rear connecting rod is precisely against the limit bolt 3526.

[0084] The following is combined with Figure 10The design of the clamping head 353 is described below. The clamping head 353 has a second mounting port 3531 at the end facing the connector head 352, which is used to install two connecting rods. The two connecting rods are the front connecting rod 354 and the rear connecting rod 355. The rear connecting rod 355 has a sliding groove in the middle for movably connecting with the pull rod. The second mounting port 3531 has second pin holes 3532 on both sides. The connecting rods are installed in the second mounting port 3531 by the pins. The minimum distance between the root of the second mounting port 3531 and the front connecting rod 354 is greater than the diameter of the metal wire, so that the metal wire in the wire feeding device 37 can pass smoothly through the clamping head 353.

[0085] Furthermore, the end of the clamping head 353 furthest from the connecting head 352 is a tapered head 3533. The threading mechanism 6 includes a fixed clamp 63 and a movable clamp 64. See [link to relevant documentation]. Figure 3 and Figure 11 As shown, the movable chuck 64 is connected to a power unit. The upper and lower parts of the rearward-facing ends of the fixed chuck 63 and the movable chuck 64 can form a Y-shaped groove for clamping the conical head 3533. The opening of the Y-shaped groove faces the rear end, and a through hole is provided at the bottom of the Y-shaped groove along the vertical direction. The through hole is located on the fixed chuck 63, and a vertical connecting channel is provided between the through hole and the outer wall of the rear end of the fixed chuck 63. The metal wire can pass through the through hole and the connecting channel under the pull of the clamping head and abut against the heat sink.

[0086] The following is combined with Figure 4 The specific structure of the wire cutting device 36 and the wire feeding device 37 is described below. The wire cutting arm 361 is fixedly mounted on the first longitudinal moving bracket 31 above the rotating arm 351. A wire cutting head 362 is provided on one side of the front end, and a wire feeding device 37 is provided on the other side.

[0087] The wire feeding device 37 includes a bottom support 371 fixed to the front end of the wire cutting arm 361. The bottom support 371 is horizontally arranged and has an L-shaped first intermediate support 372 bolted to it. The bottom surface of the first intermediate support 372 extends away from the wire cutting head 362. The upper part of the vertical surface is bolted to a U-shaped second intermediate support 373. The U-shaped opening of the second intermediate support 373 faces away from the first intermediate support 372. The upper and lower ends of the second intermediate support 373 are provided with bent edges and clamp a vertically arranged wire feeding tube 374. The wire in the wire feeding mechanism 2 can be fed into the wire feeding tube 374.

[0088] The wire cutting head 362 is located between the bottom support 371 and the lower bent edge of the second intermediate support 373. The lower end of the wire feeding tube 374 passes through the lower bent edge of the second intermediate support 373 and is located above the wire cutting head 362.

[0089] Furthermore, a guide 375 is movably connected to the bottom support 371. The guide 375 is hollow inside and located below the vertical projection of the wire feeding tube 374. The head gap hole of the clamping head 353 can rotate to the lower part of the middle through hole of the guide 375, so that the wire can be fed from the wire feeding mechanism 2 into the wire feeding tube 374, pass through the two scissor mouths of the wire cutting head 362, pass through the middle through hole of the guide 375, and then pass through the gap between the root of the second mounting port 3531 of the two clamping heads 375 and the front connecting rod 354.

[0090] Preferably, the guide member 375 can be a bolt with an internal hole, which can be easily fixed to the bottom support 371 with a nut. The relative positions of the guide member 375 and the first intermediate bracket 372 with respect to the bottom support 371 are adjustable, facilitating installation and adjustment. The relative position between the second intermediate bracket 373 and the first intermediate bracket 372 is also adjustable, facilitating installation.

[0091] See Figure 2 In this embodiment, the clamping mechanism 4 is located in the middle of the lower compartment 11. The clamping mechanism 4 includes a second transverse slide rail 41, on which a second sliding seat 42 is slidably connected to the front side. A horizontally arranged telescopic cylinder 43 is fixed to the front side of the second sliding seat 42. One end of the top rod of the telescopic cylinder 43 is connected to a clamping member 44. The clamping member 44 is a Z-shaped mechanism with the middle part arranged horizontally. One end of its two ends is fixed downward to the telescopic cylinder 43, and the other end extends upward. After the radiator is placed on the support mechanism, its height does not exceed the highest point of the clamping member 44. By controlling the movement of the telescopic cylinder 43, the clamping member 44 can be controlled to move forward or backward, thereby clamping or releasing the radiator.

[0092] Furthermore, a transmission screw is threaded through the second sliding seat 42, and the distance between several second sliding seats 42 is adjusted by a scissor-type connecting bracket 73.

[0093] In this embodiment, the support mechanism 5 includes a third transverse slide rail 51, which is parallel to the front end of the second transverse slide rail 41. A third sliding seat 52 is slidably connected to the third sliding seat 52. A longitudinally horizontally arranged support rod 53 is connected above the third sliding seat 52 through a support seat 54. The support rod extends backward to the rear of the clamping member 44, and its upper surface is higher than the middle horizontal position of the clamping member 44 but lower than the highest position of the clamping member 44.

[0094] Furthermore, a scissor-type connecting frame and a corresponding transmission screw (not shown in the figure) are also provided on one side of the third sliding seat 52 to adjust the position of several third sliding seats 52 on the third transverse slide rail 51.

[0095] See Figure 2 and Figure 3A threading mechanism 6 is provided above the foremost end of the lower compartment, which includes a fourth transverse slide rail 61, a fourth sliding seat 62, a fixed clamp 63, a movable clamp 64, and a limiting seat 65. The fourth transverse slide rail 61 is arranged parallel to the front end of the third transverse slide rail 51, and the fourth sliding seat 62 is slidably connected to it. The limiting seat 65 and the fixed clamp 63 are fixed on the fourth sliding seat 62. The movable clamp 64 is provided on one side of the fixed clamp 63. The movable clamp 64 can move closer to or away from the fixed clamp 63 by a driving device.

[0096] Furthermore, the width of the limiting seat 65 is greater than the width of the clamp, that is, after the radiator is placed on the support mechanism 5 and clamped by the clamping mechanism 4, the front end abuts against the limiting seat 65, and the rear end abuts against the upward-extending position of the clamping member 44.

[0097] See Figures 11-13 The fixed clamp 63 and the movable clamp 64 are column structures with notches on opposite sides, and the notches on opposite sides of the fixed clamp 63 and the movable clamp 64 together form a Y-shaped groove. A vertical through hole is provided in the middle of the fixed clamp 63, and the size of the through hole matches the diameter of the wire.

[0098] Furthermore, the height of the upper and lower Y-shaped grooves of the fixed chuck 63 and the movable chuck 64 are matched with the height of the two clamping heads in the rotating device 35, one above the other. The two clamping heads 353 can move forward into the upper and lower Y-shaped grooves of the chuck, and then the clamping heads 353 are fixed in the Y-shaped grooves by the movement of the movable chuck 64 for the wire threading operation.

[0099] Furthermore, a scissor-type connecting frame and a corresponding transmission screw (not shown in the figure) are also provided on one side of the fourth sliding seat 62 to adjust the position of several fourth sliding seats 62 on the fourth transverse slide rail 61.

[0100] In this embodiment, the first sliding seat 33, the support mechanism 5, the clamping mechanism 4, and the threading mechanism 6 move laterally in sync using a synchronization mechanism 7. The synchronization mechanism 7 includes a longitudinal transmission screw 71, several transverse transmission screws 72, and several scissor-type connecting frames 73. See also Figure 3 As shown, the first sliding seat 33, the support mechanism 5, the clamping mechanism 4, and the threading mechanism 6 are respectively connected to corresponding transverse transmission screws 72 and scissor-type connecting frames 73. The corresponding sliding seat is sleeved on the corresponding transverse transmission screw 72 and connected to each support position of the corresponding scissor-type connecting frame 73. The rotation of the transverse transmission screw 72 drives one end of the scissor-type connecting frame 73 to move closer to or further away from the other end, thereby adjusting the position of the corresponding sliding seat on the corresponding slide rail. The longitudinal transmission screw 71 connects all transverse transmission screws 72 to rotate synchronously through an intermediate power transmission device, such as gear transmission, thereby realizing that the first sliding seat 33, the support mechanism 5, the clamping mechanism 4, and the threading mechanism 6 move synchronously laterally using a synchronous mechanism 7.

[0101] In this embodiment, a longitudinally arranged drag chain 8 and corresponding track are provided on the inner wall of the lower compartment. When the first longitudinal moving support 31 moves longitudinally, the corresponding line on this device will move together with the drag chain 8.

[0102] The following is combined with Figures 5-8 This section introduces the specific usage method of the pre-welding equipment for radiators, including the following steps:

[0103] S1. Move the fabric thread mechanism 3 to the rear end of the clamping mechanism 4;

[0104] S2. Place the radiator on the support mechanism 5, at which point the clamping piece 44 is away from the radiator.

[0105] S3. Activate the telescopic cylinder 43 of the clamping mechanism 4 to extend it forward and push the clamping member 44 forward to clamp the radiator, so that the front end of the radiator abuts against the limit seat 65.

[0106] S4. The drive lever actuates, causing the two opposing clamping heads 353 in the rotating device 35 to separate to a distance greater than the thickness of the heat sink. Then, the threading mechanism 3 is driven forward. The two opposing clamping heads 353 in the rotating device 35 move from above and below the heat sink to the upper and lower Y-shaped grooves of the threading mechanism 6, respectively. (See above) Figure 5 As shown, the movable chuck 64 is driven to move toward the fixed chuck 63 to clamp the gripping head 353;

[0107] S5. Activate the wire feeding mechanism 2 to allow the metal wire to enter the wire feeding device 37. The wire then passes sequentially through the hole at the front of the upper clamping head 353, the vertical hole on the wire feeding mechanism 6, and the hole at the front of the lower clamping head 353, continuing to feed a length of metal wire greater than the length of the heat sink. See [link to relevant documentation]. Figure 5 As shown;

[0108] S6. Drive the yarn feeding mechanism 3 to move backward, while the yarn feeding mechanism 2 continues to feed yarn at the same speed as the backward movement speed of the yarn feeding mechanism 3. The two opposing clamping heads 353 in the rotating device 35 simultaneously pull the metal wire backward, causing the metal wire to first disengage from the through hole on the yarn threading mechanism 6 and press against the radiator. Then, the metal wire is simultaneously pulled up above and below the radiator until the clamping heads 353 move behind the clamping mechanism 4, stopping the movement of the yarn feeding mechanism 3. See [link to relevant documentation]. Figure 6 and Figure 7 As shown;

[0109] S7. The wire-cutting head 362 of the drive wire-cutting device 36 cuts the metal wire, and the drive rod moves backward to bring the two oppositely arranged clamping heads 353 together, thereby bringing the two ends of the single metal wire together. See [link to previous section] Figure 8 As shown;

[0110] S8. Drive the rotating device 35 to rotate a preset number of times, so that the two ends of the metal wire are wrapped around each other and continuously approach the rear end of the radiator until the metal wire is completely tightened on the radiator.

[0111] S9. The drive lever separates the two opposing clamping heads 353, drives the telescopic cylinder 43 of the clamping mechanism 4 to move backward, and removes the bundled radiator.
