Description

Technical Field

[0001] This invention relates to the field of radiator processing technology, specifically to a pressing radiator conveying and positioning end face leveling processing device and processing method. Background Technology

[0002] In the manufacturing process of radiators, the leveling of the radiator end faces is a crucial step. After forming, radiators often have defects such as burrs and unevenness on their end faces, which not only affect the product's appearance but also adversely impact subsequent assembly processes. With the continuous expansion of radiator production scale and the increasing level of automation, various automated processing equipment for radiator trimming, milling, or grooving has emerged in the industry. For example, existing technologies disclose devices that automatically push heat sink fins to predetermined positions using a feeding mechanism in conjunction with a positioning mechanism, followed by processing by a processing mechanism; there are also solutions that use an input platform and an output platform in conjunction with a leveling mechanism to level and mill the radiators. The application of these devices has improved the efficiency of radiator end face processing to a certain extent, realizing the transformation from manual operation to automated processing.

[0003] However, existing radiator end-face leveling processing devices still have room for improvement. On the one hand, because radiators vary in size, the relative positions of the processing and feeding mechanisms in existing equipment often need to be manually adjusted according to product specifications to accommodate the processing requirements of different radiator sizes. This not only increases operational complexity but also affects processing efficiency. On the other hand, when simultaneously leveling both ends of the radiator, the position adjustments of the processing mechanisms on both sides in existing equipment often lack good coordination, making it difficult to ensure consistency in the leveling amount on both sides. Furthermore, ensuring the radiator is accurately centered on the feeding mechanism after it is fed into the feeding mechanism is also a key factor affecting processing quality. Summary of the Invention

[0004] The purpose of this invention is to provide a pressing heat sink conveying and positioning end face flattening processing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressing radiator conveying and positioning end face trimming processing device, comprising: workbench A feeding mechanism is provided on the workbench and is used to carry the radiator for transportation; A feeding mechanism is provided on the same plane as the feeding mechanism and located on one side of the feeding mechanism, and pushes the heat sink to the feeding mechanism; The leveling mechanism consists of two sets, which are located on both sides of the feeding mechanism. The two sets of leveling mechanisms can move synchronously closer to or further away from the radiator and are used to process both ends of the radiator. The unloading mechanism is located at the discharge end of the leveling mechanism and pushes the processed radiator away from the feeding mechanism.

[0006] In some embodiments, the feeding mechanism is located at the center of the workbench, and its length matches the length of the workbench; The feeding mechanism includes a transmission unit and a fixing unit, wherein the fixing unit is located on the side of the transmission unit close to the leveling mechanism.

[0007] In some embodiments, the transmission unit includes a feeder housing disposed on the workbench, a feeder motor is provided at one end of the feeder housing, a lead screw is connected to the output end of the feeder motor, and the lead screw is threadedly connected to the fixing unit. The feeder housing is also provided with a slide rail, which is engaged with the fixing unit. A telescopic cover is fitted onto the outer side of the lead screw and the slide rail, and the end of the telescopic cover is connected to the fixing unit.

[0008] In some embodiments, the fixing unit includes a support frame, and the support frame is provided with a meshing plate and a locking block on the side near the transmission unit; The meshing plate is sleeved on the lead screw, and the locking block is locked on the slide rail; The outer side of the support frame is provided with a transverse cylinder and a longitudinal cylinder. The output end of the transverse cylinder is provided with a transverse push plate, and the output end of the longitudinal cylinder is provided with a longitudinal push plate.

[0009] In some embodiments, the leveling mechanism includes a leveling mounting frame disposed on the workbench, a leveling motor is provided on one side of the leveling mounting frame, and a leveling blade is provided at the output end of the leveling motor. The leveling mounting bracket can adjust the position of the leveling motor from the radiator.

[0010] In some embodiments, the feeding mechanism includes a feeding guard plate disposed on the workbench, a feeding roller connected in the feeding guard plate, a feeding air pump disposed at the discharge end of the feeding roller, and a feeding push plate disposed at the output end of the feeding air pump.

[0011] In some embodiments, a positioning mechanism is provided on the side opposite to the feeding mechanism, with the feeding mechanism as the core. The positioning mechanism includes a positioning mounting frame on the worktable, a positioning cylinder on the positioning mounting frame, and a positioning push plate at the output end of the positioning cylinder.

[0012] In some embodiments, the unloading mechanism includes an unloading mounting frame disposed on the workbench and located on one side of the feeding mechanism, the unloading mounting frame is provided with an unloading air pump, and the output end of the unloading air pump is provided with an unloading push plate; The feeding mechanism also includes a feeding guard plate disposed on the workbench and located on the other side of the feeding mechanism, and a feeding roller is disposed on the feeding guard plate.

[0013] In some embodiments, a collection mechanism is provided on the workbench and at the discharge end of the leveling mechanism. The collection mechanism includes a collection port opened on the workbench, a collection box connected to the collection port, and an installation port for connecting an air extraction machine at one end of the collection box.

[0014] A method for smoothing the conveying and positioning end face of a press-fit radiator, comprising the following steps: Before entering the feeding mechanism, the radiator is detected to determine its contour data. The contour data is then input into the processing device, and processing parameters are calculated. The leveling mechanism synchronously adjusts its distance from the feeding mechanism based on the processing parameters and the contour data of the radiator. The radiator enters the feeding mechanism. Before the feeding mechanism pushes the radiator, the positioning mechanism first extends to contact the radiator. The feeding mechanism pushes the radiator, and the positioning mechanism retracts. Once the position of the radiator in the feeding mechanism is determined to be centered, the positioning mechanism stops moving and marks the current position node. For subsequent processing of the radiator, the positioning mechanism only needs to extend to the position node. The feeding mechanism transfers the radiator into the leveling mechanism and performs leveling processing on the radiator. After processing, the unloading mechanism pushes the radiator away from the feeding mechanism, completing the unloading process.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The pressing radiator conveying and positioning end face leveling processing device includes: a worktable, a feeding mechanism, a loading mechanism, a leveling mechanism, and a unloading mechanism. The feeding mechanism is located on the worktable and is used to carry the radiator for transport. The transport of the radiator drives its movement, so that when it passes the leveling mechanism, the leveling mechanism automatically processes the radiator carried on the feeding mechanism. The loading mechanism is located on the same plane as the feeding mechanism and on one side of it. It pushes the radiator to the feeding mechanism. The loading mechanism is positioned adjacent to the leveling mechanism, and its pushing end is closer to the leveling mechanism. This allows the loading mechanism to enter the working range of the leveling mechanism in a shorter time after pushing the radiator, thereby improving the efficiency of radiator processing. The leveling mechanism consists of two sets, located on either side of the feeding mechanism. The two sets of leveling mechanisms can move synchronously closer to or further away from the radiator. They are used to adjust according to the size of the radiator and are used to process both ends of the radiator. The unloading mechanism is located at the discharge end of the leveling mechanism and pushes the processed radiator away from the feeding mechanism. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1-7 The present invention provides a technical solution: a pressing heat sink conveying positioning end face leveling processing device, comprising: a worktable 1, a feeding mechanism 4, a loading mechanism 2, a leveling mechanism 5, and a unloading mechanism 6.

[0020] The feeding mechanism 4 is located on the workbench 1 and is used to transport the radiator. This transport causes the radiator to move, allowing it to pass through the leveling mechanism 5, which automatically processes the radiator carried by the feeding mechanism 4. The loading mechanism 2 is located on the same plane as the feeding mechanism 4 and to one side of it. It pushes the radiator onto the feeding mechanism 4. The loading mechanism 2 is positioned adjacent to the leveling mechanism 5, with its pushing end closer to the leveling mechanism 5. This allows the loading mechanism 2 to enter the working range of the leveling mechanism 5 more quickly after pushing the radiator, thus improving the efficiency of radiator processing. The leveling mechanism 5 consists of two sets, located on either side of the feeding mechanism 4. These two sets can move synchronously closer to or further away from the radiator, adjusting according to its size. The leveling mechanism 5 processes both ends of the radiator. The unloading mechanism 6 is located at the discharge end of the leveling mechanism 5 and pushes the processed radiator away from the feeding mechanism 4.

[0021] A protective shell 11 is provided on the workbench 1. The protective shell 11 has feed inlets at both the front and rear. These inlets accommodate the feeding mechanism 4 and the radiator on it, ensuring that the feeding mechanism 4 and the radiator can enter and exit the protective shell 11. The protective shell 11 also covers the leveling mechanism 5, thus preventing debris generated during the processing of the radiator by the leveling mechanism 5 from flying everywhere.

[0022] The radiator is transported by the feeding mechanism 4, and the loading mechanism 2, leveling mechanism 5, and unloading mechanism 6 are arranged around the feeding mechanism 4 to ensure that the radiator can enter the processing area and be unloaded continuously after loading. This effectively improves the continuity of the machine's processing cycle and the efficiency of operation. At the same time, the pushing end of the loading mechanism 2 is arranged closer to the leveling mechanism 5, so that the radiator can enter the working range of the leveling mechanism 5 with a shorter stroke after being pushed, further reducing non-processing waiting time. In addition, the two sets of leveling mechanisms 5 are respectively set on both sides of the feeding mechanism 4 and can move synchronously closer to or away from the radiator. This allows the device to be adjusted synchronously on both sides according to the actual size of the radiator. This not only ensures the consistency of the leveling amount at both ends, but also avoids the processing deviation caused by unilateral adjustment, thereby significantly improving the processing quality of end face leveling and the applicability of the device.

[0023] like Figures 4-6 As shown, the feeding mechanism 4 is located at the center of the worktable 1, and its length matches the length of the worktable 1. This design allows the radiator to move from the loading mechanism 2 to the unloading mechanism 6, completing the entire processing flow. The feeding mechanism 4 includes a transmission unit and a fixing unit. The transmission unit is used by the feeding mechanism 4 to transport the radiator, while the fixing unit is used to fix the radiator. The fixing unit is located on the side of the transmission unit near the leveling mechanism 5. This position allows the radiator, fixed by the fixing device, to be released by the leveling mechanism 5 for processing.

[0024] The transmission unit includes a feeder housing 41 mounted on the workbench 1. A feeder motor 42 is mounted at one end of the feeder housing 41, and a lead screw 421 is connected to the output end of the feeder motor 42. The lead screw 421 is threadedly connected to a fixed unit. When the lead screw 421 is driven to rotate by the feeder motor 42, the fixed unit can move on the lead screw 421 by its own thread, driven by the rotation of the lead screw 421.

[0025] The feeder housing 41 is also equipped with a slide rail 45, which is used to limit the fixed unit and prevent the fixed unit from rotating with the lead screw 421. The slide rail 45 and the fixed unit are engaged.

[0026] A telescopic cover 43 is fitted onto the outer side of the lead screw 421 and the slide rail 45. The telescopic cover 43 is used to cover the lead screw 421 and the slide rail 45, and the feeding motor 42 can extend and fold. In this way, the telescopic cover 43 can cover the lead screw 421 and the slide rail 45 without affecting the coverage of the lead screw 421 and the slide rail 45. The end of the telescopic cover 43 is connected to the fixing unit. This connection method ensures that when the fixing unit moves on the slide rail 45, the folding state of the telescopic cover 43 can be synchronously adapted to the movement of the fixing unit.

[0027] The fixing unit includes a support frame 46. On the side of the support frame 46 near the transmission unit, there is a meshing plate 44 and a locking block 461. The meshing plate 44 is sleeved on the lead screw 421. A through threaded hole is formed in the meshing plate 44, which matches the outer diameter of the lead screw 421 and is sleeved on the outside of the lead screw 421. The locking block 461 is engaged with the slide rail 45. On the side of the locking block 461 near the slide rail 45, there is a matching locking groove for the slide rail 45, ensuring that the locking block 461 can engage with the slide rail 45, thereby allowing the locking block 461 to slide on the slide rail 45.

[0028] A transverse cylinder 47 and a longitudinal cylinder 48 are provided on the outer side of the support frame 46. A transverse push plate 471 is provided at the output end of the transverse cylinder 47, and a longitudinal push plate 481 is provided at the output end of the longitudinal cylinder 48. When the transverse cylinder 47 pushes the transverse push plate 471, it is used to apply transverse pressure to the radiator, thereby fixing the radiator. When the longitudinal cylinder 48 pushes the longitudinal push plate 481, it is used to apply longitudinal pressure to the radiator.

[0029] The horizontal cylinder 47, in conjunction with the vertical cylinder 48, applies bidirectional pressure to the radiator, pressing it tightly against the leveling mechanism 5, thereby ensuring that the radiator will not shake when it is being processed by the leveling mechanism 5.

[0030] In this invention, the direct engagement of the lead screw 421 with the threaded hole of the meshing plate 44 and the direct snap-fit ​​of the locking block 461 with the slide rail 45 allow the driving force and guiding force of the fixing unit to be independently borne by the lead screw 421 and the slide rail 45, respectively. This avoids a single component bearing both driving and guiding loads simultaneously, thus accelerating wear and extending the service life of the feeding mechanism 4. The meshing plate 44 and the locking block 461 are independently arranged on the side of the support frame 46 near the transmission unit, structurally decoupling the driving and guiding functions of the fixing unit. When any component needs repair or replacement, it is not necessary to disassemble the other component, reducing subsequent maintenance costs and downtime. The transverse cylinder 47 and the longitudinal cylinder 48 are independently mounted on the outside of the support frame 46 with their output directions perpendicular to each other. This allows the transverse push plate 471 and the longitudinal push plate 481 to apply pressure independently in their respective directions without interfering with each other, achieving bidirectional active pressure on the radiator. Even if there are machining errors in the radiator dimensions, the pressure in each direction can still be adaptively adjusted according to the actual dimensions, avoiding the impact on fixing reliability caused by local over-tightness or over-looseness due to dimensional deviations when applying pressure in a single direction. The transverse push plate 471 and the longitudinal push plate 481 directly act as extensions of the cylinder output end on the radiator surface, shortening the force transmission path from the cylinder power output to the pressure point of the radiator, reducing the fitting clearance and action delay that may be introduced by intermediate transmission links, and improving the fixing response speed and repeatability accuracy. The telescopic cover 43 is sleeved on the outside of the lead screw 421 and the slide rail 45 and its end is connected to the fixed unit. This structure allows the telescopic folding of the protective cover to be achieved without the need for a separate drive source or control logic. It relies entirely on the movement of the fixed unit under the drive of the lead screw 421 to achieve passive following, which reduces the number of electrical control points and power components, and lowers the overall manufacturing cost and the complexity of the control system.

[0031] like Figure 2 As shown, the leveling mechanism 5 includes a leveling mounting frame 51 mounted on the workbench 1. A leveling motor 52 is mounted on one side of the leveling mounting frame 51, and a leveling blade 53 is mounted on the output end of the leveling motor 52. The two sets of leveling mechanisms 5 are respectively arranged on both sides of the feeding mechanism 4, so that both ends of the radiator can be processed simultaneously.

[0032] The leveling mounting bracket 51 can adjust the position of the leveling motor 52 relative to the radiator. The leveling mounting bracket 51 includes a base plate and a movable bracket, which can move on the base plate, which is fixedly connected to the worktable 1, thus ensuring the leveling motor 52 moves on the worktable 1. The leveling plate 53 is driven to rotate by the leveling motor 52. This is used for grinding or cutting the radiator's ports. This type of processing ensures the radiator's ports remain flat.

[0033] Two sets of leveling mechanisms 5 are independently set on both sides of the feeding mechanism 4 and their positions are adjusted by independent leveling mounting brackets 51, so that the height and angle of the leveling motors 52 and leveling plates 53 on both sides can be adjusted independently. Even if there is a symmetry deviation at both ends of the radiator or the machining allowance of the two end faces is inconsistent, the leveling plates 53 on both sides can still set the machining parameters according to the actual state of their respective end faces, so as to realize differentiated machining of both ends of the radiator. This avoids the problem of over-cutting on one side or under-machining on the other side due to the error of the radiator itself when the two sides are forcibly adjusted uniformly, thus reducing the defect rate. The moving frame of the leveling mounting bracket 51 moves on the base plate to adjust the position of the leveling motor 52, and the base plate is fixed to the worktable 1. This structure allows the relative position adjustment between the leveling plate 53 and the heat sink end face to be completed entirely within the plane of the base plate. After adjustment, the processing reaction force of the leveling motor 52 is directly transmitted from the moving frame to the base plate fixed to the worktable 1, without relying on other intermediate support components. This ensures the positional stability and vibration resistance of the leveling plate 53 during the leveling process, which is beneficial to improving the processing accuracy of the end face flatness. The leveling motor 52 directly drives the leveling plate 53 to rotate, and the leveling plate 53 is processed by grinding or cutting. This means that the leveling mechanism 5 only needs to provide rotational driving force to complete the processing, without the need for additional feed or retraction tools or feed motion components. This simplifies the number of motion degrees of freedom and structural complexity of the leveling mechanism 5, and reduces the probability of failure. The leveling motor 52 moves and adjusts with the overall movement of the moving frame, so that the position adjustment of the leveling plate 53 and the feeding movement of the feeding mechanism 4 are independent of each other. The feeding mechanism 4 is only responsible for sending the heat sink to the preset processing position, while the leveling mechanism 5 completes the position adaptation according to the preset parameters. The motion control of the two is not coupled, which reduces the logical complexity and debugging difficulty of the whole machine control system.

[0034] like Figure 1 As shown, the feeding mechanism 2 includes a feeding guard plate 21 mounted on the workbench 1. A feeding roller 22 is connected to the feeding guard plate 21. A feeding air pump 23 is provided at the discharge end of the feeding roller 22, and a feeding push plate 24 is provided at the output end of the feeding air pump 23. The feeding guard plate 21 is connected to the feeding roller 22 via a rotating shaft, ensuring that the feeding roller 22 can rotate inside the feeding guard plate 21. The feeding guard plate 21 is trapezoidal, and the feeding rollers 22 are arranged in a certain inclination towards the leveling mechanism 5. When the radiator is placed on the feeding roller 22, the radiator will move towards the leveling mechanism 5 under the influence of gravity. When it moves to the set position, the feeding air pump 23 will push the feeding push plate 24 to push the radiator onto the support frame 46, thereby completing the feeding step.

[0035] The feeding guard plate 21 is trapezoidal, and the arrangement of the feeding rollers 22 is inclined towards the leveling mechanism 5. This allows the radiator to slide automatically along the inclined direction by its own weight after being placed on the feeding rollers 22, without the need for an additional independent drive mechanism or power supply to move the radiator within the feeding guard plate 21. This reduces the number of power components and energy consumption, simplifies the structural complexity of the feeding mechanism 2, and lowers manufacturing costs. The feeding rollers 22 are connected to the feeding guard plate 21 via a rotating shaft and can rotate freely inside the feeding guard plate 21. This allows the radiator to roll into contact with the feeding rollers 22 as it slides along the inclined direction. Compared to sliding contact, this significantly reduces frictional resistance, prevents scratches on the radiator surface due to sliding friction, and also reduces the probability of the radiator getting stuck or stopping during sliding. This improves the smoothness of the feeding process and the protection of the radiator surface. The trapezoidal structure of the feeding guard plate 21 causes the width of the feeding rollers 22 to gradually narrow from the inlet end to the outlet end, which plays a role in gradually guiding the radiator during the sliding process. This ensures that the radiator's posture is basically aligned with the receiving direction of the support frame 46 when it reaches the position of the feeding air pump 23, reducing the additional correction action required before the feeding air pump 23 pushes it and improving the accuracy of the feeding positioning. The feeding air pump 23 is located at the outlet end of the feeding rollers 22 and its pushing direction is towards the support frame 46. After the feeding rollers 22 achieve coarse positioning of the radiator by gravity sliding, the feeding air pump 23 drives the feeding push plate 24 to complete the final precise push. During the pushing process, the pushing stroke of the feeding push plate 24 is controlled by the feeding air pump 23. After being pushed into place, it can remain in the pushed-out state until the radiator is clamped by the fixing unit, effectively preventing the radiator from retreating or shifting due to inertia or vibration after pushing, and ensuring the consistency of the feeding position.

[0036] like Figure 7 As shown, a positioning mechanism 3 is provided on the side opposite to the feeding mechanism 2, with the feeding mechanism 4 as the core. The positioning mechanism 3 can limit the feeding air pump 23 to push the radiator into the feeding mechanism 4 through the feeding push plate 24 and keep it in a central position in the feeding mechanism 4. The positioning mechanism 3 includes a positioning mounting bracket 31 on the worktable 1, a positioning cylinder 32 on the positioning mounting bracket 31, and a positioning push plate 33 at the output end of the positioning cylinder 32. Before the feeding mechanism 2 works, the positioning cylinder 32 first drives the positioning push plate 33 to push to the position node to complete the positioning of the radiator pushed by the feeding mechanism 2. The positioning push plate 33 and the feeding push plate 24 are arranged horizontally opposite each other, and the side of both near the radiator is flat to keep it in close contact with the end face of the radiator and ensure that the radiator will not tilt due to pushing.

[0037] In this invention, the positioning mechanism 3 and the feeding mechanism 2 are arranged opposite each other with the feeding mechanism 4 as the axis, so that the pushing directions of the positioning push plate 33 and the feeding push plate 24 are on the same straight line and arranged in opposite directions. When the feeding push plate 24 pushes the heat sink, it is blocked by the positioning push plate 33 from the opposite direction. The two apply opposite constraint forces to both sides of the heat sink at the same time, which can effectively counteract the inertial impulse and deflection torque generated by pushing from one side, and prevent the heat sink from rebounding or deflecting due to impact with the positioning push plate 33 at the end of the pushing, thereby improving the positional consistency of the heat sink after entering the feeding mechanism 4.

[0038] Before the feeding mechanism 2 starts working, the positioning cylinder 32 drives the positioning push plate 33 to extend to the position node and remain stationary, so that the positioning push plate 33 forms a fixed physical barrier before the feeding push plate 24 starts pushing. During the pushing process, one side of the radiator always keeps in contact with the flat surface of the positioning push plate 33. The positioning push plate 33 is used as a reference to complete the end point positioning of each push, ensuring that the radiator's left and right center position in the feeding mechanism 4 does not change due to the air pressure fluctuation of the feeding air pump 23 or the weight difference of the radiator itself.

[0039] The positioning push plate 33 and the feeding push plate 24 are both flat surfaces on the side closest to the radiator and are horizontally opposed to each other. This allows the radiator to be pushed onto the positioning push plate 33, with both end faces of the radiator forming surface contact with the flat surfaces of the positioning push plate 33 and the feeding push plate 24, respectively. Compared to point contact or line contact, surface contact can distribute the pushing force evenly to various areas of the radiator end face, avoiding indentations or deformation of the radiator end face due to localized force concentration. It also ensures that the radiator's posture before clamping is parallel to the processing reference of the leveling mechanism 5, reducing the end face perpendicularity error introduced by the radiator's posture deviation during subsequent leveling processing.

[0040] The positioning push plate 33 extends out before loading and remains in the same position throughout the loading and processing process. Once the position node of the positioning push plate 33 is set, it is used as a fixed reference for repeated use. The positioning of each heat sink is referenced to the same position node. There is no need to re-inspect or adjust the extension length of the positioning push plate 33 each time it is loaded, thus eliminating the cumulative positioning error caused by repeated changes in the positioning reference.

[0041] like Figure 2 As shown. The unloading mechanism 6 includes an unloading mounting frame 61 located on the workbench 1 and on one side of the feeding mechanism 4. An unloading air pump 62 is mounted on the unloading mounting frame 61, and an unloading push plate 63 is mounted on the output end of the unloading air pump 62. When the feeding mechanism 4 moves the pre-processed radiator into the range of the unloading mechanism 6, the unloading mechanism 6 pushes the radiator from the feeding mechanism 4 onto the lower feeding mechanism 4, where it falls onto the unloading roller 65.

[0042] The unloading mechanism 6 also includes an unloading guard plate 64 located on the worktable 1 and on the other side of the feeding mechanism 4, with an unloading roller 65 mounted on the unloading guard plate 64. The unloading guard plate 64 and the unloading roller 65 are connected by a rotating shaft, and the unloading roller 65 can rotate inside the unloading guard plate 64. The unloading guard plate 64 has a certain curvature, so when the radiator is on the unloading roller 65, it can automatically move downwards under its own weight.

[0043] A collection mechanism 7 is provided on the workbench 1 at the discharge end of the leveling mechanism 5. The collection mechanism 7 includes a collection port 71 on the workbench 1, and a collection box 72 is connected to the collection port 71. One end of the collection box 72 has an installation port 73 for connecting a vacuum pump. The vacuum pump is used to absorb the metal scraps and fumes generated during the processing of the radiator by the leveling mechanism 5, and allows them to be absorbed through the collection port 71. The collection box 72 is used to store the metal scraps, while the fumes are drawn away by the vacuum pump.

[0044] When the heat sink conveying and positioning end face leveling processing device is used, before the heat sink enters the feeding mechanism 2, the front detection unit first scans and detects its shape to obtain the three-dimensional contour data of the heat sink. This data is input into the control system of the processing device, and the control system automatically calculates the processing parameters based on the contour data, including the distance value between the two sets of leveling mechanisms 5 and the leveling feed amount. According to the calculation results and the actual size of the heat sink, the leveling mechanism 5 synchronously adjusts its distance relative to the feeding mechanism 4 so that the gap between the two sets of leveling plates 53 and the two end faces of the heat sink is consistent, completing the adaptive adjustment before processing.

[0045] Subsequently, the radiator is placed on the feeding roller 22 of the feeding mechanism 2. Since the feeding guard plate 21 is trapezoidal and the arrangement of the feeding roller 22 is inclined towards the leveling mechanism 5, the radiator automatically slides along the inclined direction by its own gravity and rolls to the discharge end of the feeding roller 22. Before the feeding mechanism 2 pushes the radiator, the positioning cylinder 32 of the positioning mechanism 3 first drives the positioning push plate 33 to extend to the preset position node, forming a fixed physical barrier. Then, the feeding air pump 23 drives the feeding push plate 24 to push the radiator towards the positioning push plate 33. The radiator moves forward under the push of the feeding push plate 24 until one of its end faces is tightly attached to the flat surface of the positioning push plate 33. At this time, the radiator is clamped between the feeding push plate 24 and the positioning push plate 33, completing the left and right centering positioning on the feeding mechanism 4. Subsequently, the feeding pusher 24 releases its push, and the positioning pusher 33 retracts to make room for processing. The control system stores the extension length data of the positioning cylinder 32 at this position node as a reference for subsequent processing positioning.

[0046] After positioning, the transverse cylinder 47 drives the transverse push plate 471, and the longitudinal cylinder 48 drives the longitudinal push plate 481, applying pressure to the radiator on the support frame 46 from both transverse and longitudinal directions, thus achieving bidirectional clamping and fixing of the radiator. Then, the feeding motor 42 starts, driving the lead screw 421 to rotate. The meshing plate 44, through its threaded engagement with the lead screw 421, moves the support frame 46 along the slide rail 45 towards the leveling mechanism 5. The telescopic cover 43 folds or unfolds synchronously with the movement of the support frame 46, maintaining coverage and protection for the lead screw 421 and the slide rail 45. The support frame 46, carrying the clamped and fixed radiator, moves to the processing station of the leveling mechanism 5. Two sets of leveling motors 52 drive the leveling plates 53 to rotate synchronously, simultaneously leveling both ends of the radiator.

[0047] After the leveling process is completed, the transverse cylinder 47 and the longitudinal cylinder 48 release their pressure on the radiator, and the feeding motor 42 continues to drive the support frame 46 to move the radiator towards the discharge end into the working range of the unloading mechanism 6. The unloading air pump 62 drives the unloading push plate 63 to extend, pushing the radiator from the support frame 46 onto the unloading roller 65. Due to the curvature of the unloading guard plate 64, the radiator automatically rolls down along the unloading roller 65 under its own gravity, completing the unloading process. At the same time, the exhaust fan continuously absorbs the metal scraps and fumes generated during the leveling process through the collection port 71. The scraps are collected in the collection box 72, and the fumes are discharged by the exhaust fan.

[0048] A method for smoothing the conveying and positioning end face of a press-fit radiator, comprising the following steps: Before entering the feeding mechanism 2, the radiator is inspected. The three-dimensional contour data of the radiator is obtained by scanning, the contour data of the radiator is determined, and the contour data is compared with the preset standard model. The contour data is then input into the processing device, and the control system automatically generates and calculates the processing parameters based on the contour data. The processing parameters include at least the distance between the two flattening mechanisms 5 and the flattening feed. The flattening mechanism 5 adjusts its distance from the feeding mechanism 4 synchronously according to the processing parameters and the contour data of the radiator, so that the gap between the flattening plates 53 of the two sets of flattening mechanisms 5 and the two end faces of the radiator is consistent.

[0049] The radiator enters the feeding mechanism 2, is placed on the feeding roller 22, and slides towards the discharge end by gravity. Before the feeding mechanism 2 pushes the radiator, the positioning cylinder 32 drives the positioning push plate 33 to extend to the preset position node. The positioning mechanism 3 first extends to contact the radiator, so that the flat surface of the positioning push plate 33 forms a surface contact with one end face of the radiator. The feeding mechanism 2 pushes the radiator, and the feeding air pump 23 drives the feeding push plate 24 to push the other end face of the radiator, so that the radiator is clamped and centered between the positioning push plate 33 and the feeding push plate 24. The positioning mechanism 3 retracts, so that the positioning push plate 33 is separated from the contact with the end face of the radiator and makes room for processing.

[0050] The position of the radiator in the feeding mechanism 4 is determined to be centered. The symmetry of the radiator in the width direction of the feeding mechanism 4 is determined with the extension position of the positioning push plate 33 as the reference. The positioning mechanism 3 stops moving and marks the current position node. The control system records the extension length data of the positioning cylinder 32 corresponding to the position node. In subsequent radiator processing, the positioning mechanism 3 directly calls the stored position node data. The positioning mechanism 3 only needs to extend to the position node to complete the centering and positioning of any batch of radiators without repeated detection or readjustment.

[0051] The feeding mechanism 4 transfers the radiator into the leveling mechanism 5. The support frame 46 of the fixed unit moves along the slide rail 45 to transport the radiator to the processing station and performs leveling processing on the radiator. Two sets of leveling motors 52 drive the leveling blades 53 to rotate synchronously and level both ends of the radiator at the same time. After processing, the transverse cylinder 47 and the longitudinal cylinder 48 release the pressure and fixation on the radiator. The unloading mechanism 6 pushes the radiator away from the feeding mechanism 4. The output end of the unloading mechanism 6 extends forward and pushes the radiator out of the support frame 46, completing the unloading process.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
