Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration evaporator processing, and more particularly to an integrated refrigeration evaporator processing device and a processing technology thereof. Background Art

[0002] In the field of refrigeration equipment manufacturing, the integrated evaporator is a core component, and its performance and quality are directly related to the operating efficiency and stability of the entire refrigeration system. The integrated evaporator is mainly composed of copper tubes and fins. The copper tubes are inserted into the fins and tightly fit to achieve efficient heat exchange.

[0003] Currently, the process of threading the copper tubes into the fins is a critical step in the manufacturing of integrated refrigeration evaporators on the market. However, most manufacturers still rely primarily on manual threading. Manual threading is not only inefficient but also requires high operator skills, is labor-intensive, and has relatively high labor costs. Furthermore, the quality of manual threading is difficult to guarantee, and problems such as misalignment and loose fit between the copper tubes and the fins can easily occur, which in turn affects the heat exchange performance of the evaporator.

[0004] With the development of automation technology, some companies have tried to introduce automatic pipe threading equipment to replace manual operations. However, the automatic pipe threading equipment in the existing technology has obvious limitations when dealing with fins of different specifications and structures. Due to the various opening distribution forms of the fins, the most common ones are inclined distribution, vertical distribution, and other situations. The existing automatic pipe threading mechanisms are mostly designed as a single structure, which lacks flexibility and adaptability. When faced with fins with different opening distributions, it is often necessary to perform complex disassembly and replacement operations on the pipe threading mechanism, which not only increases the debugging time and maintenance costs of the equipment, but also seriously affects production efficiency. Moreover, frequent disassembly and replacement operations may also lead to a decrease in equipment accuracy, further affecting the quality of pipe threading. Summary of the Invention

[0015] The present invention is further configured as follows: the welding mechanism also includes a screw, a sliding seat and a welding part; the screw is rotatably arranged at the top of the first bracket, and the screw is located above the flipping table after flipping; the sliding seat is slidably arranged at the top of the first bracket, and a linear groove for limiting the sliding of the sliding seat is opened at the top of the first bracket; the welding part is rotatably arranged at the bottom of the sliding seat.

[0016] By adopting the above technical solution, when the position of the welding part needs to be adjusted, the motor first drives the screw to rotate, and when the screw rotates, it can drive the sliding seat to slide along the linear groove opened on the top of the first bracket. In this state, the sliding seat and the welding part can slide along the horizontal arrangement direction of the flipping table after flipping, so that the position of the welding part can be adjusted according to the position of the bent pipes after multiple pipes are passed through.

[0020] The present invention further provides a refrigeration evaporator processing process, which is applied to the above-mentioned integrated refrigeration evaporator processing equipment, and includes the following steps: S1. First, the first robotic arm clamps the copper tube to be threaded and places it on the top of the sliding table. Then, multiple first clamping parts clamp the copper tube to be threaded. After clamping, the first linear guide rail drives the sliding table to slide toward the turning table. At this time, the preliminary threading of the copper tube and fin to be threaded is completed.

After the preliminary pipe threading work is completed, the second clamping part clamps the elbow to be threaded, and after clamping, the displacement part slides toward the turning table through the second linear guide rail until the elbow to be threaded is connected with the other end of the copper pipe after threading, thereby realizing the automatic pipe threading work of the copper pipe to be threaded, the fin and the elbow, and can be adaptively adjusted according to the inclination angle of the fin opening.

[0022] S3. After the pipe threading work is completed, the turning table is in a turning state away from the first linear guide rail until the turning table is located below the welding part, and then the welding part performs welding work on the turned bent pipe and the copper pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects: By setting up a pipe threading mechanism, multiple first clamping parts clamp the copper pipe to be threaded. After clamping, in order to adjust the inclination of the copper pipe to be threaded to be consistent with the inclination of the fin opening, the multiple first flipping parts drive the first clamping parts to rotate, and then the inclination of the multiple copper pipes to be threaded can be adjusted to ensure that the inclination of the copper pipe to be threaded is consistent with the inclination of the fin opening. This process completes the first pipe threading operation of the copper pipe to be threaded, which is the initial pipe threading stage after the elbow and the copper pipe are welded. Subsequent pipe threading operations focus on the butt-jointing threading of the elbow and the other end of the copper pipe to be threaded. It solves the problem of needing to disassemble and replace the pipe threading mechanism to meet the pipe threading requirements of the fin when the inclination of the fin opening is inconsistent, thereby improving the adaptability of pipe threading.

[0024] By setting a second linear guide rail, a displacement part, a second flipping part and a second clamping part, when the second clamping part and the elbow to be threaded are tilted, the second linear guide rail drives the displacement part to approach the position of the flipping table until the second clamping part completes the plugging action of the elbow to be threaded and the other end of the copper tube after the preliminary threading. At this time, the threading work of the copper tube to be threaded, the fin and the elbow to be threaded is completed.

[0025] By setting up a welding mechanism, when the position of the welding part needs to be adjusted, the motor first drives the screw to rotate. When the screw rotates, it can drive the sliding seat to slide along the linear groove opened at the top of the first bracket. In this state, the sliding seat and the welding part can slide along the horizontal arrangement direction of the flip table after flipping, so that the position of the welding part can be adjusted according to the position of multiple pipes after pipe threading. When the rotating disk rotates, it can drive the welding part to rotate synchronously, and then the welding part can weld according to the different inclinations of the fins and the bent pipes after pipe threading. There is no need to manually hold the welding part to perform welding work, which improves welding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] See also Figure 1-13 , the present invention provides the following technical solutions: Embodiment 1 includes a housing 1, a first robotic arm 2 disposed on the top of the housing 1 and used to grab and carry the copper tube to be threaded, a second robotic arm 3 disposed on the top of the housing 1 and used to grab and carry the fin to be threaded, and a turning table 4 disposed on the top of the housing 1 for placing the fin to be threaded. The integrated refrigeration evaporator processing equipment also includes a pipe threading mechanism 5 and a welding mechanism 6; the pipe threading mechanism 5 has a pair and is respectively disposed on the top of the housing 1. The pipe threading mechanism 5 includes a first linear guide rail 51, a sliding table 52, a first turning portion 53, and a first clamping portion 54; The first linear guide rail 51 is arranged on the top of the casing 1 and is located next to the first robotic arm 2; the sliding platform 52 is slidably arranged on the top of the first linear guide rail 51, and the sliding platform 52 is used to place the copper pipe to be threaded; the first flipping part 53 has multiple and is rotatably arranged next to the sliding platform 52; the first clamping part 54 has multiple and is rotatably arranged next to the first flipping part 53, and the first clamping part 54 is used to clamp the copper pipe to be threaded; the welding mechanism 6 is arranged on the top of the casing 1, and the welding mechanism 6 is used to weld the bent pipes and copper pipes to be welded after threading.

[0031] Specifically, the sliding table 52 is consistent in height with the turning table 4 and is on the same horizontal plane, so as to prevent the problem of misalignment of the pipe threading in the subsequent pipe threading operation. Rotating motors for driving the turning table 4 to flip are respectively provided on both sides of the turning table 4. The rotating motors are preferably servo motors. When the rotating motors are started, the turning table 4 can be driven to flip away from the housing 1. After the fins and copper tubes are threaded and welded by the welding mechanism 6, the second robotic arm 3 is used to clamp and carry the processed fins and copper tubes, so as to complete the unloading and transportation action. The top of the turning table 4 is provided with a rotating part 41 for abutting the fins against the top of the turning table 4. Servo motors for driving the rotating part 41 to rotate are provided on both sides of the rotating part 41. When the servo motors are started, the rotating part 41 can be driven to flip. When performing the pipe threading operation, the second robotic arm 3 first places the assembled fins on top of the turning table 4, and then the rotating part 41 rotates until the bottom of the rotating part 41 is in contact with the top of the fin and stops rotating. In this state, the fins can be abutted against the top of the turning table 4 by the rotating part 41, which can prevent the fins from being displaced during the subsequent pipe threading process. Then the first robotic arm 2 places multiple copper tubes to be assembled between multiple first clamping parts 54, and then multiple first clamping parts 54 clamp the copper tubes to be threaded. After clamping, in order to adjust the inclination of the copper tubes to be threaded to be consistent with the fin opening, the multiple first turning parts 53 drive the first clamping parts 54 to rotate, and then the inclination of the multiple copper tubes to be threaded can be adjusted to ensure that the inclination of the copper tubes to be threaded is consistent with the fin opening. This process completes the first pipe threading operation of the copper tubes to be threaded, which is the initial pipe threading stage after the elbow and the copper tube are welded. Subsequent pipe threading operations focus on the butt-jointing of the elbow and the other end of the copper tube to be threaded. The problem that the pipe threading mechanism 5 needs to be disassembled and replaced to meet the pipe threading requirements of the fins when the opening inclinations of the fins are inconsistent is solved, thereby improving the pipe threading adaptability.

[0032] See Figure 3 The pipe welding mechanism 6 also includes a synchronous wheel 55 and a synchronous belt 56; there are multiple synchronous wheels 55 and they are respectively arranged on the sides of the first flipping part 53; the synchronous belt 56 is arranged on the side of the sliding table 52, and the synchronous belt 56 is engaged with the synchronous wheel 55. When the synchronous belt 56 rotates, it can drive the multiple synchronous wheels 55 and the first flipping part 53 to rotate.

[0033] Specifically, a plurality of abutment wheels for abutting the rotation of the synchronous belt 56 are rotatably provided on the side of the sliding table 52. The plurality of abutment wheels abut above each of the synchronous wheels 55. When the synchronous belt 56 rotates, the abutment wheels can stably drive the rotational force of the synchronous belt 56 to rotate the plurality of synchronous wheels 55. A transmission chain for driving the sliding table 52 toward the flip table 4 is provided on the side of the second linear guide 592. This is prior art and will not be elaborated on here. A rotating synchronous wheel 55 meshing with the synchronous belt 56 is provided on the side of the sliding table 52, and a rotary driver for driving the rotating synchronous wheel 55 to rotate is provided at the input end of the rotating synchronous wheel 55. The rotary driver is preferably a servo motor. When the servo motor is started, it can drive the synchronous belt 56 to rotate. When the synchronous belt 56 rotates, it can drive the plurality of synchronous wheels 55 and the flip part to rotate. An electric push rod can be installed beside the sliding platform 52 to drive the multiple abutment wheels toward the synchronous belt 56. This serves as the tension control mechanism for the synchronous wheels 55 and the synchronous belt 56. This is a conventional technique and will not be described in detail here. This mechanism can then rotate the copper tube to be threaded, held by the first clamping portion 54, allowing the copper tube to be threaded at different rotation angles for adaptive threading and docking with fins of varying inclinations.

[0034] See Figure 3-Figure 7 The pipe threading mechanism 5 also includes a first telescopic cylinder 57, a second telescopic cylinder 58, a first ejection portion 59 and a first hinged rod 591; the first telescopic cylinder 57 is arranged beside the sliding platform 52, and the first telescopic cylinder 57 is located at the top of the first flip portion 53; the second telescopic cylinder 58 is arranged beside the sliding platform 52, and the second telescopic cylinder 58 is located at the bottom of the first flip portion 53; the first ejection portion 59 is arranged at the output end of the first telescopic cylinder 57 and the second telescopic cylinder 58; the first hinged rod 591 has a plurality of and is rotatably arranged at the top of the first ejection portion 59, one end of the first hinged rod 591 is rotatably connected to the first ejection portion 59, and the other end of the first hinged rod 591 is rotatably connected to the first clamping portion 54. When the first ejection portion 59 slides in the direction away from the sliding platform 52, the first hinged rod 591 can drive the first clamping portion 54 to be in a relatively close clamping state.

[0035] Specifically, when the first robotic arm 2 places multiple copper tubes to be threaded between the multiple clamping sections, the first telescopic cylinder 57 and the second telescopic cylinder 58 are first activated. When the first telescopic cylinder 57 and the second telescopic cylinder 58 are activated, they drive the first ejection section 59 to slide away from the sliding platform 52. During this process, the multiple first hinged rods 591 drive the rotatably connected first clamping sections 54 into a relatively close clamping state. After the multiple first clamping sections 54 clamp the copper tubes to be threaded, the first linear guide 51 drives the sliding platform 52 toward the turning platform 4. As the sliding platform 52 moves, the multiple clamped copper tubes to be threaded and the fin openings can be automatically threaded. This process completes the first threading operation of the copper tubes to be threaded, which is the initial threading stage after the elbow and the copper tube are welded. Subsequent threading operations focus on the butt-jointing threading of the elbow and the other end of the copper tube to be threaded.

[0036] Embodiment 2 is to ensure the stable connection between the bent pipe and the copper pipe after the pipe is inserted.

[0037] See Figure 4-Figure 8 The pipe threading mechanism 5 also includes a second linear guide rail 592, a displacement portion 593, a second flip portion 594 and a second clamping portion 595; the second linear guide rail 592 is arranged at the top of the housing 1 and is located next to the first linear guide rail 51; the displacement portion 593 is slidably arranged on the top of the second linear guide rail 592; the second flip portion 594 has a plurality of and is respectively arranged next to the displacement portion 593; the second clamping portion 595 has a plurality of and is respectively rotatably arranged next to the flip portion, and the second clamping portion 595 is used to clamp the bent pipe to be connected.

[0038] Specifically, the second linear guide 592 is used to drive the displacement section 593 to slide toward the turning table 4. The second linear guide 592 includes a pair of drive screws 64, which are conventional techniques and will not be elaborated upon here. When the other end of the copper tube, after the initial threading, needs to be threaded, the second robotic arm 3 first clamps the bent tube to be threaded and places it between the multiple second clamping sections 595. The multiple second clamping sections 595 then clamp the multiple bent tubes to be threaded. After clamping, the multiple second turning sections 594 rotate to adjust the inclination of the multiple bent tubes, driving the multiple second clamping sections 595 to rotate synchronously. The displacement section 593 is also flanked by multiple synchronous pulleys 55 and a synchronous belt 56 located outside the synchronous pulleys 55. A rotary actuator is also provided to the displacement section 593 to drive the multiple synchronous pulleys 55 and the synchronous belt 56. When the rotary actuator is activated, the synchronous belt 56 rotates, thereby driving the multiple second turning sections 594 to rotate synchronously. When the second clamping part 595 and the bent pipe to be threaded are tilted, the second linear guide rail 592 drives the displacement part 593 to approach the position of the turning table 4 until the second clamping part 595 completes the plug-in action of the bent pipe to be threaded and the other end of the copper pipe after the preliminary threading. It should be noted that the bent pipe and the other end of the copper pipe are plug-in matched. At this time, the threading work of the copper pipe to be threaded, the fin and the bent pipe to be threaded is completed.

[0039] See Figure 4-Figure 8 The pipe-threading mechanism 5 also includes a third cylinder 596, a second ejection part 597 and a second hinged rod 598; the third cylinder 596 has multiple parts and is respectively arranged at the top and bottom of the flip part; the second ejection part 597 has multiple parts and is respectively arranged at the output end of the third telescopic cylinder. When the third telescopic cylinder is started, it can drive the second ejection part 597 to move away from the displacement part 593; the second hinged rod 598 has multiple parts and is respectively rotatably arranged on the second ejection part 597, one end of the second hinged rod 598 is rotatably connected to the second ejection part 597, and the other end of the second hinged rod 598 is rotatably connected to the second clamping part 595.

[0040] Specifically, when the plurality of second clamping parts 595 need to be driven to clamp the elbow to be threaded, the plurality of third cylinders 596 are first activated and drive the plurality of second ejecting parts 597 to slide away from the displacement part 593. At this time, the plurality of second hinged rods 598 can drive the plurality of rotatably connected second clamping parts 595 to be relatively close to each other for clamping, thereby achieving the clamping of the elbow to be threaded.

[0041] Embodiment 3 is to ensure the cleanliness of the copper tube and the bent tube during welding after flipping and to solve the problem of manually holding the welding part 66 for welding.

[0042] See Figure 9The welding mechanism 6 includes a first bracket 61, an air pump 62 and an air blowing pipe 63; the first bracket 61 is arranged at the top of the casing 1 and above the second linear guide rail 592; the air pump 62 is arranged beside the first bracket 61, and the air pump 62 is above the second linear guide rail 592; the air blowing pipe 63 is arranged beside the air pump 62, and the bottom of the air blowing pipe 63 is located above the turning table 4.

[0043] Specifically, when the copper pipes and bent pipes to be threaded are completed and welding is required, the air pump 62 is first started and air is discharged through the bottom of the air blow pipe 63. Since the exhaust port at the bottom of the air blow pipe 63 is located above the bent pipe after threading, the air blow pipe 63 can then perform air jet cleaning on the bent pipe after threading, ensuring effective cleaning before welding and guaranteeing the quality of subsequent welding.

[0044] See Figure 10-11 The welding mechanism 6 also includes a screw rod 64, a sliding seat 65 and a welding portion 66; the screw rod 64 is rotatably set at the top of the first bracket 61, and the screw rod 64 is located above the flip table 4 after flipping; the sliding seat 65 is slidably set at the top of the first bracket 61, and a linear groove for limiting the sliding of the sliding seat 65 is opened at the top of the first bracket 61; the welding portion 66 is rotatably set at the bottom of the sliding seat 65.

[0045] Specifically, a motor is provided at the top of the first bracket 61 to drive the screw 64, preferably a servo motor. To adjust the position of the welding portion 66 and enable it to weld multiple pipes to the copper tube after the pipe is inserted, the rotating motors on both sides of the turning table 4 are first activated. In this state, the rotating motors are in contact with the fins after the pipe is inserted. Then, the rotating motors and the rotating portion 41 rotate synchronously until the turning table drives the pipe to be positioned below the welding portion 66. The welding portion 66 is preferably an electromagnetic induction heating welding device, which uses electromagnetic coil heating welding to locally heat the welding portion 66 through the principle of electromagnetic induction, achieving an efficient and precise weld connection. To adjust the position of the welding portion 66, the motor first drives the screw 64 to rotate. When the screw 64 rotates, it drives the sliding seat 65 to slide along the linear groove formed in the top of the first bracket 61. In this state, the sliding seat 65 and the welding portion 66 can slide along the horizontal arrangement direction of the turning table 4 after the turning, so that the position of the welding portion 66 can be adjusted according to the position of the multiple pipes after the pipe is inserted.

[0046] See Figure 10-13The welding mechanism 6 also includes a first hydraulic cylinder 67, a lifting plate 68, a second hydraulic cylinder 69 and a movable seat 691; the first hydraulic cylinder 67 is arranged at the top of the sliding seat 65; the lifting plate 68 is slidably arranged at the bottom of the sliding seat 65, and the top of the lifting plate 68 is connected to the output end of the first hydraulic cylinder 67; the second hydraulic cylinder 69 is arranged beside the lifting plate 68; the movable seat 691 is slidably arranged at the bottom of the lifting plate 68, and the movable seat 691 is connected to the output end of the second hydraulic cylinder 69, and the movable seat 691 is located above the welding part 66.

[0047] Specifically, when the position of the welding portion 66 needs to be adjusted, the first hydraulic cylinder 67 is first activated to drive the lifting plate 68 downward. When the lifting plate 68 descends, it drives the movable seat 691 and the welding portion 66 to descend synchronously, thereby achieving the raising and lowering of the welding portion 66. When the second hydraulic cylinder 69 is activated, it drives the movable seat 691 to slide on the bottom of the lifting plate 68 away from the turning portion, thereby achieving the vertical, lateral, and horizontal position adjustment of the welding portion 66.

[0048] See Figure 12 The welding mechanism 6 also includes a rotating support rod 692 and a rotating disk 693; the rotating support rod 692 is rotatably set on the top of the movable seat 691, and the top of the lifting plate 68 is provided with a kidney hole for the displacement of the rotating support rod 692; the rotating disk 693 is rotatably set on the top of the movable seat 691 and is located below the lifting plate 68, and the bottom of the rotating disk 693 is connected to the top of the welding part 66. When the rotating disk 693 rotates, it can drive the welding part 66 to rotate synchronously.

[0049] Specifically, a rotary driver for driving the rotating disk 693 to rotate is provided on the top of the movable seat 691, and the rotary driver is preferably a servo motor. When the movable seat 691 moves, it can drive the rotating support rod 692 to move synchronously on the top of the lifting plate 68, which can reduce the sliding friction between the welding part 66 and the movable seat 691. In order to enable the welding part 66 to perform welding work on the position of the bent pipe after the pipe is inserted, the rotary driver is first rotated to drive the rotating disk 693 to rotate. When the rotating disk 693 rotates, it can drive the welding part 66 to rotate synchronously, and then the welding part 66 can perform welding work on the different inclinations of the fins and the bent pipe after the pipe is inserted. There is no need to manually hold the welding part 66 for welding, which improves the welding efficiency.

[0050] In a fourth embodiment, the present invention further provides a refrigeration evaporator processing process, which is applied to the above-mentioned integrated refrigeration evaporator processing equipment, and includes the following steps: S1. First, the first robotic arm 2 clamps the copper tube to be threaded and places it on the top of the sliding table 52. Then, multiple first clamping parts 54 clamp the copper tube to be threaded. After clamping, the first linear guide rail 51 drives the sliding table 52 to slide toward the turning table 4. At this time, the preliminary threading work of the copper tube and fin to be threaded is completed.

[0051] S2. After the preliminary pipe threading work is completed, the second clamping part 595 clamps the elbow to be threaded, and after clamping, the displacement part 593 slides toward the turning table 4 through the second linear guide rail 592 until the elbow to be threaded is connected with the other end of the copper pipe after threading, thereby realizing the automatic pipe threading work of the copper pipe to be threaded, the fin and the elbow, and can be adaptively adjusted according to the inclination angle of the fin opening.

[0052] S3. After the pipe threading work is completed, the turning table 4 is turned away from the first linear guide rail 51 until the turning table 4 is located below the welding part 66. Then the welding part 66 welds the turned bent pipe and the copper pipe.

[0053] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
