Description

Technical Field

[0001] This invention relates to the field of radiator fin manufacturing and processing technology, and in particular to a radiator fin sorting device and a fin splicing machine. Background Technology

[0002] A tape splicing machine (also called a feeder or splicer) is simply an automated device that automatically joins the ends of two continuous strips of material together, enabling continuous production without stopping the machine for roll changing. In the manufacturing process of automotive radiators, the strip splicing machine is also a core processing equipment. It transports the strip material to the cutting part for cutting, and then transports the cut fins one by one to the designated position to wait for subsequent fin assembly or storage operations. During the transport process, the flat fins need to be turned into a vertical position and stacked neatly to meet the requirements of the subsequent assembly process.

[0003] Currently, conventional fin sorting equipment on the market mainly relies on inclined chute material feeding combined with independent pushing mechanism and fixed baffle to complete the stacking operation. The movement of each part relies only on the timing set by electrical control, and the structural coordination is rigid. There is no mechanical trajectory linkage structure. Therefore, in the actual sorting process, the vertically placed fins are very prone to lateral tilting, tipping, edge bending and overall twisting. There is no follow-up correction and limit structure, making it difficult to straighten the fin posture in real time during the stacking process. The fin arrangement is not neat, and the stack shape is loose and irregular, which seriously affects the subsequent feeding and processing accuracy. At the same time, the discharge end of traditional sorting equipment is difficult to achieve continuous feeding, resulting in insufficient production continuity. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a radiator fin sorting device, which fundamentally solves the problem that the current fin sorting equipment has a rigid structure and fit, which makes the fins prone to lateral tilting, tipping, edge bending and overall twisting during the sorting process, resulting in poor subsequent feeding effect and low processing accuracy.

[0005] According to an embodiment of the present invention, a heat sink fin sorting device includes a conveying assembly, a sorting table, a monitoring assembly disposed at the top of the sorting table and located at the discharge end of the conveying assembly, and a sorting assembly disposed on the side of the monitoring assembly away from the conveying assembly and connected to the conveying path of the conveying assembly. The sorting assembly includes a pusher assembly that pushes the fins out of the conveying path along the Y-axis, and a baffle assembly disposed on the pusher path of the pusher assembly to flatten the fins in the X-axis direction. At least part of the pusher assembly and the baffle assembly enclose a conveying space that is connected to the conveying path of the conveying assembly. The monitoring assembly is electrically connected to the pusher assembly and the baffle assembly. The fins are guided by the conveying assembly to rotate from the horizontal to the vertical and enter the conveying path. After passing the monitoring assembly, the monitoring assembly sequentially wakes up the baffle assembly to open the conveying space and wakes up the pusher assembly to push the fins out of the conveying space.

[0006] Furthermore, the conveying assembly includes an external platform for connecting to the discharge port of an external device, a feed guide plate disposed on the top of the external platform, a conveying guide rail disposed at the bottom of the feed guide plate, and a positive positioning side plate extending outward along at least one side of the conveying guide rail.

[0007] Furthermore, the positive side plate and the conveying guide rail are inclined at an angle of 30° to 60°, so that the fins that are laterally introduced into the positive side plate can tilt along its inclination angle and slide vertically into the conveying guide rail.

[0008] Furthermore, the monitoring assembly includes a sensor for monitoring the position of the fins on the conveying path, a control unit electrically connected to the position sensor and used to control the pusher assembly and the baffle assembly respectively, and a limiting part disposed opposite to the control unit and used to accommodate at least part of the baffle assembly, wherein a slot is provided between the limiting part and the control unit for the fins to pass through.

[0009] Furthermore, the pusher assembly includes a pusher component for pushing fins, a clamping component disposed on the opposite side of the pusher component, and a linkage component disposed between the pusher component and the clamping component for transmission connection between the two, so that the pusher component and the clamping component move in opposite directions on the sorting table to achieve clamping and sorting of the fins along the Y-axis.

[0010] Furthermore, the feeding assembly includes a second driving part disposed on the top of the sorting table, a feeding plate disposed at the output end of the second driving part, and a material limiting member slidably disposed on the feeding plate to limit the length of the fins.

[0011] Furthermore, the clamping assembly includes a positioning clamp plate at least partially embedded in the top of the sorting table, a sliding stage disposed below the positioning clamp plate, at least two second elastic portions extending outward along the side of the sliding stage away from the push plate, and a limiting wheel disposed between the positioning clamp plate and the sliding stage and abutting against the inner wall of the sorting table, wherein the second elastic portions are fixedly connected to the inner wall of the sorting table along the Y-axis.

[0012] Furthermore, the linkage component includes a fixed roller disposed on the inner wall of the sorting table and near the second drive unit, at least two fixed pulleys sleeved on the fixed roller, a linkage cable wound around the fixed pulleys and connected at both ends to the pusher plate and the bottom of the sliding table respectively, and a first elastic part disposed on the linkage cable near the sliding table.

[0013] Furthermore, the baffle assembly includes a lifting baffle that is at least partially embedded in the top of the sorting table and arranged parallel to the pusher plate, a first driving part disposed at the bottom of the lifting baffle for driving its lifting and lowering, a first limiting platform extending outward along the middle of the lifting baffle, and a flip-plate assembly movably embedded in the top of the sorting table and driven by the first limiting platform. The flip-plate assembly includes a movable shaft movably connected to the sorting table, a movable flip-plate connected to the movable shaft, and a second limiting platform extending outward along the side of the movable flip-plate away from the movable shaft and overlapping with the sorting table. The lifting baffle drives the flip-plate assembly to push the top fins up and tilt them towards the lower side along the X-axis, thereby aligning and sorting the fins on the X-axis.

[0014] In addition, the present invention also provides a tape splicing machine, including a radiator fin straightening device disposed on the tape splicing machine.

[0015] Compared with the prior art: The radiator fin sorting device in the above embodiments of the present invention guides the fins to rotate from the horizontal to the vertical direction and enter the conveying path through the conveying assembly. After passing the monitoring assembly, the monitoring assembly sequentially wakes up the baffle assembly to open the conveying space and wakes up the pushing assembly to push the fins out of the conveying space. During the pushing process, the intermediate fins are pressed and aligned along the Y-axis. After completing the above-mentioned fin pushing, the baffle assembly opens again, and the first drive unit drives the lifting baffle to rise, so as to re-close the conveying space and wait for the next step. As the fins continue to enter, the lifting baffle drives the flip-plate assembly to flip and lift, causing the fins above the flip-plate assembly to be lifted and tilted along the X-axis. During this process, the side of the fins that are lifted will slide uniformly towards the lower side, realizing the sorting and regulation of the stacked fins along the Y-axis to X-axis during the fin pushing process. This solves the problem that the current fin sorting equipment has a rigid structure, which makes the fins prone to lateral tilting, tipping, edge bending and overall twisting during the sorting process, resulting in poor subsequent feeding effect and low processing accuracy.

[0022] Please see Figures 1 to 6The image shows a radiator fin sorting device according to an embodiment of the present invention. It includes a conveying assembly 1, a sorting table 5, a monitoring assembly 2 disposed at the top of the sorting table 5 and located at the discharge end of the conveying assembly 1, and a sorting assembly disposed on the side of the monitoring assembly 2 away from the conveying assembly 1 and connected to the conveying path of the conveying assembly 1. The sorting assembly includes a pushing assembly 3 that pushes the fins out of the conveying path along the Y-axis, and a baffle assembly 4 disposed on the pushing path of the pushing assembly 3 to flatten the fins along the X-axis. At least a portion of the pushing assembly 3 and the baffle assembly 4 enclose and form a connection with the conveying assembly 1. The conveying path of the conveying assembly 1 is connected to the conveying space. The monitoring assembly 2 is electrically connected to the pushing assembly 3 and the baffle assembly 4. The conveying assembly 1 guides the fins to flip from the horizontal to the vertical and enter the conveying path. After passing the monitoring assembly 2, the monitoring assembly 2 sequentially wakes up the baffle assembly 4 to open the conveying space and wakes up the pushing assembly 3 to push the fins out of the conveying space. In some optional embodiments, in order to avoid the fins from getting stuck and accumulating material during the conveying process, a pushing cylinder can be added based on the inlet of the conveying path and the side close to the external platform 11.

[0023] Furthermore, the conveying assembly 1 includes an external platform 11 for connecting to the discharge port of an external device, a feed guide plate 12 disposed on the top of the external platform 11, a conveying guide rail 13 disposed at the bottom of the feed guide plate 12, and a positive positioning side plate 14 extending outward along at least one side of the conveying guide rail 13. The monitoring assembly includes a position sensor 21 for monitoring the position of the fins on the conveying path, a control unit 22 electrically connected to the position sensor 21 and used to control the pushing assembly 3 and the baffle assembly 4 respectively, and a limiting part 23 disposed opposite to the control unit 22 and used to accommodate at least part of the baffle assembly 4. Figure 3As shown, the limiting part 23 is also provided with a sliding groove adapted to the lifting baffle 42, so that the lifting baffle 42 slides vertically along the sliding groove trajectory to ensure the stability of the sliding process. An empty groove is provided between the limiting part 23 and the control part 22 for the fins to pass through. The pushing assembly 3 includes a pushing component for pushing the fins, a clamping component disposed on the opposite side of the pushing component, and a linkage component disposed between the pushing component and the clamping component for the transmission connection between the two, so that the pushing component and the clamping component move in opposite directions on the sorting table 5 to realize the clamping and sorting of the fins along the Y-axis. The pushing component includes a second driving part 7 disposed on the top of the sorting table 5, a pushing plate 31 disposed on the output end of the second driving part 7, and a slidably disposed on the pushing plate 31 to implement the fin length. The material limiting component 32 is designed to limit the movement of fins. It should be noted that the pusher plate 31 also has corresponding scale markings. The operator can slide the material limiting component 32 along the trajectory of the pusher plate 31 based on the current length of the sorted fins. Tensioning bolts on the material limiting component 32 are used to tension and fix it to the pusher plate 31. When the fins are in the conveying space, their rear end can abut against the adjusted material limiting component 32, achieving fin limiting and preventing subsequent fins from being pushed out at any position in the conveying space, thus avoiding fin stacking and disorder. The clamping assembly includes a positioning clamping plate 39 at least partially embedded in the top of the sorting table 5, a sliding table 37 located below the positioning clamping plate 39, at least two second elastic portions 38 extending outwards from the side of the sliding table 37 away from the pusher plate 31, and... A limiting wheel 310 is positioned between the positioning clamping plate 39 and the sliding table 37 and abuts against the inner wall of the sorting table 5. In some optional embodiments, at least two slide rails adapted to the limiting wheel 310 are provided on the top inner side of the sorting table 5 to ensure smooth sliding of the subsequent clamping components. The second elastic part 38 is fixedly connected to the inner wall of the sorting table 5 along the Y-axis. The linkage component includes a fixed roller 33 disposed on the inner wall of the sorting table 5 and near the second drive part 7, at least two fixed pulleys 34 sleeved on the fixed roller 33, a linkage cable 35 wound around the fixed pulleys 34 and connected at both ends to the push plate 31 and the bottom of the sliding table 37 respectively, and a first elastic part 36 is provided on the linkage cable 35 near the sliding table 37. The baffle assembly 4 includes at least partially embedded in the sorting table 37. The table 5 has a lifting baffle 42 that is parallel to the top of the push plate 31, a first drive unit 41 that is set at the bottom of the lifting baffle 42 for driving its lifting and lowering, a first limiting platform 43 that extends outward from the middle of the lifting baffle 42, and a flip plate assembly 44 that is movably embedded in the top of the sorting table 5 and driven by the first limiting platform 43. The flip plate assembly 44 includes a movable shaft 442 that is movably connected to the sorting table 5, a movable flip plate 441 that is connected to the movable shaft 442, and a second limiting platform 443 that extends outward from the side of the movable flip plate 441 away from the movable shaft 442 and overlaps with the sorting table 5. The flip plate assembly 44 is driven by the lifting baffle 42 to push the top fins to lift up and tilt to the lower side along the X-axis, so as to align and sort the fins on the X-axis.

[0024] It should be noted that the first elastic part 36 and the second elastic part 38 may be made of tension springs or rubber with good rebound effect, and the first drive part 41 and the second drive part 7 may be made of motors or cylinders, but are not limited to.

[0025] In specific implementation, firstly, the operator can install the external platform 11 at the discharge port of the fin cutting station on the tape receiving machine to complete the assembly of the radiator fin sorting device of this application. Afterwards, the operator can debug the radiator fin sorting device. During the debugging process, the fin speed can be derived according to the current cutting station. The controller can sequentially control the opening of the push cylinder, monitoring assembly 2, push assembly 3 and baffle assembly 4 at the conveying guide rail 13. In some optional embodiments, the controller can be installed on the sorting table 5 at any position convenient for the operator to operate, and the controller can be an MCU (Microcontroller Unit).A microcontroller unit (MCU) chip is used to control the entire heat sink fin arrangement device. The controller can also be electrically connected to the heat sink fin arrangement device, including wired and wireless connections. Wireless connections include, but are not limited to, Bluetooth, WiFi, IF radio frequency, and Zigbee. Wired connections include, but are not limited to, network communication lines connecting the heat sink fin arrangement device and the controller. Afterwards, the fins are guided along the positive side plate 14 into the conveyor rail 13, where the positive side plate 14 and the conveyor rail 13 are at an angle of 30° to 60°. The tilt angle is set so that the fins, which are laterally introduced onto the positive side plate 14, can tilt along the tilt angle and slide vertically into the conveying guide rail 13. After entering the conveying guide rail 13, the pushing cylinder can be activated once every 1 to 3 seconds according to the current speed of the fins entering the conveying assembly 1, pushing the fins along the conveying path into the conveying space to achieve smooth fin conveying. In addition, in some optional embodiments of the present invention, the design of the conveying guide rail 13 can also be a progressive design with gradually decreasing gaps from the side of the external platform 11 towards the side of the monitoring assembly 2, so that the flat conveying of the fins is completed smoothly. The fins are rotated and conveyed smoothly and uniformly into the conveying space, which not only slows down the sliding speed of the fins and avoids impact deformation and collision damage, but also completes the initial limit correction during the conveying process to prevent the fins from being skewed and stacked. At the same time, it smoothly connects the preceding and following processes, ensuring that the fins enter the subsequent linkage and sorting operations in a regular posture. During the process, after the fins pass through the monitoring area of ​​the positioning sensor 21, the positioning sensor 21 sends a trigger signal to the control unit 22. The control unit 22 then sends control quality to the pusher assembly 3 and the baffle assembly 4 and executes the corresponding fin pushing and sorting operations. Specifically, the control unit 22 controls the operation. The first drive unit 41 activates and controls the lifting baffle 42 to move towards embedding or extending from the sorting table 5. During the process of the first drive unit 41 controlling the lifting baffle 42 to embed into the sorting table 5, the first limiting platform 43 can drive the movable flap 441, which overlaps its surface, to follow its descent trajectory and rotate along the movable axis 442. This causes the movable flap 441, which was originally protruding from the surface of the sorting table 5, to lower and stop after the second limiting platform 443 completes its overlap with the surface of the sorting table 5, maintaining a horizontal position with the sorting table 5. In this state, one side of the conveying space formed by the lifting baffle 42 and the pusher plate 31 is open.

[0026] Furthermore, the pusher assembly 3 opens, pushing the fins out along the Y-axis. Specifically, the second drive unit 7 pushes the pusher plate 31, causing the fins to move closer to or further away from the positioning clamping plate 39. During this process, the pusher plate 31 drives the linkage cable 35 to move around the fixed pulley 34, and the linkage cable 35 drives the sliding table 37 to move closer to the pusher plate 31. It should be noted that the driving stroke of the second drive unit 7 each time is greater than or equal to half the length of the linkage cable 35 to ensure that the pusher plate 31 can engage with the positioning clamping plate each time. 39 contacts, and in this process, the intermediate fins are pressed and aligned along the Y-axis to prevent the fins from being skewed or wavy. In addition, in some optional embodiments, in order to avoid the fins being damaged by excessive pressure during the clamping process between the pusher plate 31 and the alignment clamping plate 39, the first elastic part 36 and the second elastic part 38 provided on the sliding table 37 and the linkage cable 35 can provide a certain pressure resistance without affecting the normal stroke of the alignment clamping plate 39, thereby improving the protection during the fin pressing process.

[0027] Next, after completing the above-mentioned fin push, the second drive unit 7 drives the pusher plate 31 to retract, and the positioning clamp 39 is driven by the pulling force of the second elastic part 38 to slide towards the position opposite to the pusher plate 31. Then the baffle assembly 4 opens again, and the first drive unit 41 drives the lifting baffle 42 to lift up, so as to re-close the conveying space and wait for the subsequent fins to enter. During the process, the lifting baffle 42 drives the first limiting platform 43 to make one side of the movable flip plate 441 rotate and lift around the movable axis 442, and drive the fins located above the movable flip plate 441 to lift and tilt along the X-axis. During the process, the side of the fins that are lifted will slide uniformly towards the lower side and achieve limiting regulation at the measuring baffle 6. It can be understood that the alignment of one side of the fins is achieved, and the above steps are repeated to achieve the sorting and regulation of the stacked fins along the Y-axis to X-axis during the fin push process, and finally complete the fin sorting operation.

[0028] In summary, the radiator fin sorting device in the above embodiments of the present invention guides the fins from the horizontal direction to the vertical direction through the conveying assembly 1 and into the conveying path. After passing the monitoring assembly 2, the monitoring assembly 2 sequentially activates the baffle assembly 4 to open the conveying space and activates the pushing assembly 3 to push the fins out of the conveying space. During the pushing process, the intermediate fins are pressed and aligned along the Y-axis. After completing the above-mentioned fin pushing, the baffle assembly 4 opens again, and the first driving unit 41 drives the lifting baffle 42 to lift up, so as to close the conveying space again to wait for subsequent... As the fins enter, the lifting baffle 42 drives the flip plate assembly 44 to flip and lift, causing the fins above the flip plate assembly 44 to be lifted and tilted along the X-axis. During this process, the side of the fins that are lifted will slide uniformly towards the lower side, realizing the sorting and regulation of the stacked fins along the Y-axis to X-axis during the fin pushing process. This solves the problem that the current fin sorting equipment has a rigid structure, which makes the fins prone to lateral tilting, tipping, edge bending and overall twisting during the sorting process, resulting in poor subsequent feeding effect and low processing accuracy.
