Description

Technical Field

[0001] This invention relates to the field of automotive heat sink processing technology, and in particular to an automotive heat sink loading and unloading mechanism. Background Technology

[0002] Automotive radiators are devices used to dissipate heat from easily heated components in a car. They are typically made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. During the production process, radiators often undergo electroplating, a process that uses electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. This process uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing corrosion, improving wear resistance, conductivity, reflectivity, and enhancing aesthetics. This process can effectively improve the performance and appearance of automotive parts.

[0003] The car radiator is placed in the electroplating rack. After electroplating and cleaning, it needs to enter the next drying process. During the transfer process, the car radiator is usually taken out of the electroplating rack by hand and sent to the next station. This results in slow loading and unloading speed during the transfer process of the car radiator and low overall processing efficiency.

[0004] Therefore, this application provides an automotive radiator loading and unloading mechanism to solve the above problems. Summary of the Invention

[0005] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automotive radiator loading and unloading mechanism that can realize the automatic handling of automotive radiators, reduce the labor intensity of workers, and improve the processing efficiency of automotive radiators.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automotive heat sink loading and unloading mechanism, comprising at least one set of disassembly and assembly tables and a return conveyor line. A heat sink placement table is provided on the side of the return conveyor line. At least one heat sink loading and unloading robot is provided between the return conveyor line and the disassembly and assembly table. Each heat sink loading and unloading robot is provided with at least two mechanical claws at its gripping end. The disassembly and assembly table includes at least one set of hanger positioning frames for placing hangers and a top cover removal mechanism located above it. The top cover removal mechanism is provided with several screw guns for removing the top cover of the hanger, so that the electroplated heat sink can be taken out from the hanger and replaced with an unplated heat sink. The return conveyor line is located on the side of the disassembly and assembly table and can transport the electroplated heat sink to the next work station.

[0007] Furthermore, a fixed support frame is provided on the disassembly / removal platform. The top cover disassembly mechanism includes a lifting drive unit 1 vertically mounted on a support plate on the fixed support frame and a lifting platform located at its driving end. Several screwdrivers are mounted on the lifting platform. The lifting drive unit 1 can drive the lifting platform to move up and down, so that the screwdrivers move towards or away from the hanging fixture below.

[0008] Furthermore, the top cover disassembly mechanism also includes multiple sets of top cover moving assemblies, each connected to a fixed support frame via a lifting plate mounted on a displacement bracket. Each top cover moving assembly includes a top cover pressing assembly and a top cover clamping assembly. The top cover pressing assembly includes two top cover pressing cylinders vertically mounted on the lower surface of the lifting plate, each with a pressure plate at its drive end. The top cover clamping assembly includes a bidirectional cylinder horizontally positioned between the two pressing cylinders, with its two drive ends connected to hooks via clamping support plates. After the top cover is disassembled, the bidirectional cylinder drives the two clamping support plates to move relative to each other, causing the two hooks to engage with the top cover from the sides and clamp it securely from both sides. This prevents the top cover from falling off the top cover moving assembly during lifting or lowering, thus avoiding damage.

[0009] Furthermore, a positioning post is vertically installed on each side of the lifting plate along its length. A fixing block is installed at one end of each positioning post, and two springs are fixed to the lower surface of the lifting plate, each spring correspondingly fitted into a positioning post. The positioning posts are positioned to correspond to the positioning holes on the top cover of the hanger. When the top cover is reinstalled, the piston rod of the top cover pressing cylinder extends to press the top cover onto the hanger body. At this time, the springs change from a contracted state to an extended state. After the piston rod of the top cover pressing cylinder retracts, its elastic force further pushes the top cover onto the hanger body, ensuring the top cover is installed correctly and will not affect subsequent electroplating.

[0010] Furthermore, the hanger positioning frame is symmetrically equipped with hanger limiting components along its length direction centerline. Each hanging limit component includes a limiting block, a pressing component symmetrically arranged along the width direction centerline of the hanger positioning frame, and a clamping component. The pressing component includes a vertically arranged pressing cylinder and a clamping block located at its driving end. The clamping component includes a horizontally arranged clamping cylinder on the lower surface of the hanger positioning frame and a clamping block located at its driving end. The upper surface of the limiting block abuts against the lower surface of the hanger, providing support when the hanger is placed on the hanger positioning frame.

[0011] After the hanger is placed on the hanger positioning frame, the downward pressure cylinder drives the clamping block to move downward, pressing both ends of the hanger along its length onto the hanger positioning frame from top to bottom, preventing it from shifting vertically during the subsequent removal and placement of the heat sink; the piston rod of the clamping cylinder extends to drive the clamping block to move toward the side of the hanger, so that the left and right sides of the hanger are clamped between the two clamping components, thereby limiting its positional movement in the left and right directions.

[0012] Furthermore, the return conveyor line includes an upper conveyor belt arranged parallel to each other, a roller conveyor line, and lifting and lowering components respectively located at both ends of the roller conveyor line along its length. The roller conveyor line and the upper conveyor belt form a circulating conveying channel. Electroplated heat sinks removed from the hanger are placed on the roller conveyor line by a heat sink loading / unloading robot. The roller conveyor line moves multiple heat sinks to the lifting components, and under the action of the lifting components, they move upwards to the upper conveyor belt and are then moved into the upper conveyor belt, where they are conveyed to the next workstation. This effectively reduces the floor space occupied by the conveyor line.

[0013] Furthermore, the lifting assembly includes a lifting frame and a lifting roller line that moves up and down along the lifting frame via a lifting drive assembly. The lowering assembly includes a feeding bracket and a feeding roller line that moves up and down along the feeding bracket via a feeding cylinder. The lifting roller line is used to lift and transport the heat sinks on the roller conveyor line to the upper conveyor belt, so that the upper conveyor belt can transport them to the next processing station. The extension and retraction of the piston rod of the feeding cylinder can drive the feeding roller line to move up or down, adjusting the height of the heat sinks transported from the upper conveyor belt to the feeding roller line, so that they can smoothly enter the next processing station.

[0014] Furthermore, a heat sink placement platform is provided on the side of the return conveyor line, and at least one heat sink loading / unloading robot is provided between the return conveyor line and the assembly / disassembly platform. Each heat sink loading / unloading robot has at least two mechanical claws at its gripping end. The heat sink loading / unloading robot has two mechanical claws. One mechanical claw is used to grab the heat sink that has been electroplated in the fixture and place it on the return conveyor line for automatic transport to the next processing station. The other mechanical claw is used to grab the heat sink that has not been processed and is to be electroplated on the heat sink placement platform and place it in the empty fixture on the fixture positioning frame. This realizes the alternation of electroplated heat sinks and heat sinks to be electroplated. In the above operation, the electroplated heat sinks and heat sinks to be electroplated are picked up and placed simultaneously, which can further improve the loading / unloading speed of heat sinks.

[0015] Furthermore, the mounting bracket positioning frame is provided in two sets, both of which are slidably connected to the disassembly / removal table surface via a displacement support plate. The heat sink is placed in the mounting bracket for electroplating. After electroplating, it is picked up by an externally mounted lower robotic arm and placed sequentially on the mounting bracket positioning frame. The displacement support plate is moved so that the mounting bracket positioning frame with the mounting bracket installed is located below the top cover removal mechanism. Several screwdrivers are positioned according to the location of the connection holes on the mounting bracket top cover, allowing simultaneous operation to remove the screws and thus remove the lower mounting bracket top cover.

[0016] Furthermore, the assembly / disassembly platform is also equipped with buffer lines for buffering the electroplated heat sink mounting brackets and mounting bracket loading / unloading conveyor lines on both sides.

[0017] The beneficial effects of this invention are:

[0018] In this invention, the disassembly and assembly platform, the hanger positioning frame, the hanger disassembly mechanism, and the return conveyor line work together. The disassembly and assembly platform can automatically disassemble and assemble the hanger top cover placed on the hanger positioning frame, so as to exchange and replace the pre-plated heat sink with the heat sink to be plating, thereby realizing the automatic handling of automotive heat sinks, reducing the labor intensity of workers, and improving the processing efficiency of automotive heat sinks.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0030] See appendix Figures 1 to 9 As shown, an automotive radiator loading and unloading mechanism in this embodiment includes at least one set of disassembly and assembly tables 2 and a return conveyor line 11. See attached figure. Figure 1 The return conveyor line 11 is provided with a heat sink placement platform 1 on its side for placing heat sinks that need to be electroplated in advance.

[0031] At least one heat sink loading / unloading robot 14 is installed between the return conveyor line 11 and the assembly / disassembly station 2. Each heat sink loading / unloading robot 14 has at least two mechanical claws at its gripping end. The heat sink loading / unloading robot 14 has two mechanical claws. One claw is used to grab the pre-plated heat sink from the fixture and place it on the return conveyor line 11 for automatic transport to the next processing station. The other claw is used to grab the unprocessed heat sink awaiting plating on the heat sink placement station 1 and place it in an empty fixture on the fixture positioning frame 6. This allows for the alternating replacement of pre-plated and unplated heat sinks. Furthermore, the synchronous loading and unloading of pre-plated and unplated heat sinks further improves the loading / unloading speed.

[0032] In some embodiments, two heat sink loading and unloading robots 14 are provided to replace manual loading, which can reduce the labor intensity of workers to a certain extent and improve the loading and unloading efficiency of heat sinks.

[0033] The disassembly / removal platform 2 includes at least one set of mounting bracket positioning frames 6 for placing the mounting brackets and a top cover removal mechanism 10 located above it. The top cover removal mechanism 10 is equipped with several screw guns 102 for removing the top cover 8 of the mounting brackets, so that the electroplated heat sinks can be removed from the mounting brackets and replaced with unplated heat sinks. See Appendix. Figure 3 In some embodiments, the mounting bracket 6 is provided in two sets, both of which are slidably connected to the table surface of the disassembly and assembly platform 2 via a displacement support plate 4. The heat sink is placed in the mounting bracket for electroplating. After electroplating, it is picked up by an externally installed lowering robot and placed sequentially on the mounting bracket 6. The displacement support plate 4 is moved so that the mounting bracket 6 with the mounting bracket installed is located below the top cover disassembly mechanism 10. Several screw guns 102 are set according to the position of the connecting holes on the mounting bracket top cover 8, and can work simultaneously to remove the screws on them, thereby removing the lower mounting bracket top cover 8.

[0034] After the top cover 8 of the mounting fixture is removed, the pre-plated heat sink inside can be taken out and placed on the return conveyor line 11, where it will automatically move to the next station. Simultaneously, the heat sink to be electroplated is installed into an empty mounting fixture, the top cover 8 is closed back into place, and the screw gun 102 is reversed to tighten the top cover 8 back onto the fixture. Finally, an externally mounted robotic arm picks up the heat sink and places it at the electroplating station for electroplating.

[0035] In some embodiments, the displacement support plate 4 is driven to move back and forth along the first direction of the disassembly and assembly platform 2 by the horizontal displacement component 3. Specifically, the horizontal displacement component 3 can be a drive cylinder or a moving module, as long as it is a known mechanical structure that can drive the entire displacement support plate 4 to move.

[0036] The movable setting of the displacement support plate 4 facilitates the adjustment of the position of the two hanger positioning frames 6 on it, so that the two hanger positioning frames 6 can be accurately moved to the bottom of the top cover removal mechanism 10 for the removal operation of the hanger top cover 8.

[0037] See appendix Figures 4 to 5 The mounting bracket 6 is symmetrically provided with mounting bracket limiting components 7 along its center line to prevent the mounting bracket placed on the mounting bracket 6 from moving during the removal or placement of the heat sink on the mounting bracket top cover 8, thus affecting the operation.

[0038] Specifically, the hanger limiting assembly 7 includes a limiting block 71, a pressing assembly 72 symmetrically arranged along the center line of the width direction of the hanger positioning frame 6, and a clamping assembly 73. The pressing assembly 72 includes a vertically arranged pressing cylinder 721 and a clamping block 722 located at its driving end. The clamping assembly 73 includes a clamping cylinder 731 horizontally arranged on the lower surface of the hanger positioning frame and a clamping block 732 located at its driving end. The upper surface of the limiting block 71 abuts against the lower surface of the hanger. When the hanger is placed on the hanger positioning frame 6, the limiting block 71 can support its placement.

[0039] After the hanger is placed on the hanger positioning frame 6, the pressing cylinder 721 drives the clamping block 722 to move downward, pressing the two ends of the hanger in the length direction onto the hanger positioning frame 6 from top to bottom, so as to prevent it from shifting in the vertical direction during the subsequent removal and placement of the heat sink; the piston rod of the clamping cylinder 731 extends to drive the clamping block 732 to move towards the side of the hanger, so that the left and right sides of the hanger are clamped between the two clamping components 73, thereby limiting its positional movement in the left and right directions.

[0040] In some embodiments, the hanger positioning frame 6 includes two parallel and spaced positioning rods 61. The two positioning rods 61 and the limiting block 71 form a limited space for the hanger to be supported and placed. When the hanger is placed, it is located between the two positioning rods 61. The two positioning rods 61 can limit the movement of the hanger in the second direction.

[0041] Specifically, the second direction is parallel to the movement of the displacement support plate 4.

[0042] See appendix Figure 6 The disassembly / removal platform 2 is equipped with a fixed support frame 9. The top cover disassembly mechanism 10 includes a lifting drive component 1 vertically mounted on a support top plate 91 on the fixed support frame 9 and a lifting platform 101 located at its driving end. Several screwdrivers 102 are mounted on the lifting platform 101. The lifting drive component 1 can drive the lifting platform 101 to move up and down, so that the screwdrivers 102 move towards or away from the hanging device below. Each screwdriver 102 is driven by a rotary drive component 1033, which is a rotary drive motor.

[0043] When it is necessary to remove the top cover 8 of the hanger, the piston rod of the lifting drive unit extends, driving the screw gun 102 on the lifting platform 101 to move downward and close to the hanger until the screw gun 102 abuts against the screw on the hanger, automatically removing the screw. After the removal is completed, the piston rod of the lifting drive unit can retract and move away from the hanger, making it easier to remove and place the heat sink later.

[0044] In some embodiments, the lifting drive can be a known mechanical structure such as a telescopic cylinder or a linear module that can drive the lifting platform 101 to move up and down.

[0045] See appendix Figure 7 The top cover disassembly mechanism 10 further includes multiple sets of top cover moving components 103, and the multiple sets of top cover moving components 103 are all connected to the fixed support frame 9 through lifting plates 1032 that are lifted and lowered on the displacement bracket 1031. The top cover moving component 103 includes a top cover pressing component and a top cover clamping component. The top cover pressing component includes two top cover pressing cylinders 1034 that are vertically arranged on the lower surface of the lifting plate 1032. Each top cover pressing cylinder 1034 has a pressure plate 1035 at its driving end.

[0046] The mounting bracket 5 is equipped with a spring mechanism. When reinstalling the mounting bracket top cover 8, it needs to be pressed down to ensure that the top cover 8 is fully engaged with the bracket. Therefore, after the mounting bracket top cover 8 is removed and a new automotive radiator fin is inserted, the mounting bracket top cover 8 closes. At this time, the piston rod of the top cover cylinder 1034 extends to drive the pressure plate 1035 downward until it contacts the upper surface of the mounting bracket top cover 8, further applying downward pressure to the top cover 8 and pressing it firmly onto the mounting bracket 5 below, thus ensuring that the bracket and the top cover are fully engaged. During this process, no manual pressing of the top cover is required, which effectively reduces the labor intensity of workers and reduces the company's labor costs.

[0047] The top cover clamping assembly includes a bidirectional cylinder 1036 horizontally positioned between two top cover clamping cylinders 1034. The two drive ends of the bidirectional cylinder 1036 are connected to hooks 1038 via clamping support plates 1037. When disassembling the top cover 8, the bidirectional cylinder 1036 drives the two clamping support plates 1037 to move relative to each other, causing the two hooks 1038 to hook onto the sides of the top cover 8 and clamp it from both sides. This ensures the stability of the top cover during movement.

[0048] The fixed support frame 9 also includes a displacement support plate 2 92 symmetrically arranged thereon, and the displacement support plate 2 92 is arranged along the moving direction of the displacement support plate 1 4, and the straight line of the length direction of the displacement support plate 2 92 is perpendicular to the straight line of the length direction of the support top plate 91.

[0049] The displacement bracket 1031 is set between the two displacement support plates 92 and is slidably connected to the displacement support plates 92. The sliding drive component here is a displacement module to adjust the position of the top cover moving component 103 and the hanger. When one of the top cover moving components 103 needs maintenance, the other spare top cover moving component 103 can operate normally to achieve non-stop operation of the equipment and ensure the loading and unloading efficiency of the heat sink.

[0050] In some embodiments, the displacement bracket 1031 is provided with two telescopic cylinders, and the telescopic ends of the two telescopic cylinders are connected to the two ends of the lifting plate 1032 in the length direction.

[0051] The extension and retraction of the telescopic cylinder can compensate for the downward movement distance of the top cover pressing cylinder 1034, ensuring that the pressure plate 1035 can completely press the top cover 8 of the hanger onto the hanger.

[0052] In some embodiments, a positioning post 1039 is vertically inserted through both sides of the lifting plate 1032 along its length. A fixing block is provided at one end of each positioning post 1039. Two springs 1040 are fixedly provided on the lower end face of the lifting plate 1032, and each spring 1040 is correspondingly sleeved within a positioning post 1039. The positioning post 1039 is positioned corresponding to the positioning hole on the top cover of the hanger. When the top cover of the hanger is reinstalled, the piston rod of the top cover pressing cylinder extends to press the top cover of the hanger onto the hanger body. At this time, the spring changes from a contracted state to an extended state. After the piston rod of the top cover pressing cylinder retracts, its elastic force can further push the top cover of the hanger onto the hanger body, ensuring that the top cover of the hanger is installed in place and will not affect the subsequent electroplating.

[0053] The return conveyor line 11 is located on the side of the assembly / disassembly station 2 and can transport the electroplated heat sinks to the next workstation. See Appendix. Figures 8 to 9 The return conveyor line 11 includes an upper conveyor belt 113 arranged parallel to each other, a roller conveyor line 111, and lifting components 112 and lowering components respectively arranged at both ends of the length direction of the roller conveyor line 111. The roller conveyor line 111 and the upper conveyor belt 113 form a circulating conveying channel through the roller conveyor line 111. The electroplated heat sinks taken out of the hanger are placed on the roller conveyor line 111 by the heat sink unloading robot 14. The roller conveyor line 111 drives multiple heat sinks to the lifting components 112, and under the action of the lifting components 112, they move upward to the upper conveyor belt 113 and are moved into the upper conveyor belt 113, where they are conveyed to the next station. This effectively reduces the floor space occupied by the conveyor line.

[0054] The lifting assembly 112 includes a lifting frame 1121 and a lifting roller line 1122 that moves up and down along the lifting frame 1121 via a lifting drive assembly 1123. The lowering assembly includes a feeding bracket 115 and a feeding roller line 114 that moves up and down along the feeding bracket 115 via a feeding cylinder 116. The lifting roller line 1122 is used to lift and transport the heat sinks on the roller conveyor line 111 to the upper conveyor belt 113 so that the upper conveyor belt 113 can transport them to the next processing station. The extension and retraction of the piston rod of the feeding cylinder 116 can drive the feeding roller line 114 to move up or down, adjusting the height of the heat sinks transported from the upper conveyor belt 113 to the feeding roller line 114 so that they can smoothly enter the next processing station.

[0055] In some embodiments, the lifting drive assembly 1123 includes a lifting drive motor, a drive master gear located at its drive end, and a drive slave gear. The drive master gear and the drive slave gear are connected by a drive chain. When the lifting drive motor drives the drive master gear to rotate, the drive chain can drive the lifting roller line 1122 to move upward or downward.

[0056] The assembly / disassembly platform 2 is also equipped with a buffer line 12 for buffering the mounting brackets with electroplated heat sinks and a mounting bracket loading / unloading conveyor line 13 on both sides. The mounting bracket loading / unloading conveyor line 13 is used to transport multiple empty mounting brackets without heat sinks in the initial state. When the mounting bracket loading / unloading conveyor line 13 transports the empty mounting brackets to the assembly / disassembly platform 2, the externally installed upper hanging robot can grab the empty mounting brackets and place them on the mounting bracket positioning frame 6. The mounting bracket top cover 8 is removed in sequence, the mounting bracket to be electroplated is placed, and the mounting bracket top cover 8 is sealed. Finally, the externally installed lower hanging robot grabs the mounting bracket 5 with unplated heat sinks and places it to the electroplating station for electroplating. After electroplating, it enters the assembly / disassembly platform 2 for recycling.

[0057] After the heat sink is electroplated, the hanging robot will pick up the empty hanger from the hanger positioning frame 6 and put it onto the hanger loading and unloading conveyor line 13 for recycling.

[0058] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
