Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automatic bending and forming technology of condensers, specifically relating to an automatic loading and unloading bending machine. Background Technology
[0002] Condenser fins are the core heat dissipation components of condensers in refrigeration systems such as air conditioners, refrigerators, automotive air conditioners, and industrial refrigeration equipment. Essentially, they are thin metal sheets attached to the surface of the copper (or aluminum) tubes of the condenser. Through their synergistic action with the tube body, they enable the rapid dissipation of heat during the conversion of the high-temperature gaseous refrigerant to the low-temperature liquid refrigerant in the condenser fins of the refrigeration system. They are a key component for ensuring the heat dissipation efficiency and operational performance of refrigeration equipment.
[0003] The condenser fin positioning process in existing equipment heavily relies on manual operation. Operators must manually place the condenser fins on the bending machine's processing station, relying solely on experience to align the positioning reference. This is prone to errors due to placement deviations, leading to misalignment during bending. Furthermore, improper force control during manual handling can easily deform the condenser fins, further affecting processing accuracy. In addition, the speed and stability of manual loading and unloading are greatly affected by the operator's condition, resulting in variations in bending dimensions between different batches and even within the same batch. This leads to a high defect rate, making it difficult to meet the processing requirements of high-precision condenser fins. Therefore, those skilled in the art have developed an automated loading and unloading bending machine to address these problems. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic loading and unloading bending machine with a simple structure and reasonable design in order to solve the above problems.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: an automatic loading and unloading bending machine, including a condenser fin loading conveyor, a first robotic arm is provided on one side of the condenser fin loading conveyor, a loading clamp is installed at the output end of the first robotic arm, a first automatic bending machine and a second automatic bending machine are provided at the position of the condenser fin loading conveyor, which cooperate with the loading clamp through the first robotic arm, the second automatic bending machine is located on one side of the first automatic bending machine, a second robotic arm is provided on one side of the second automatic bending machine, a unloading clamp is installed at the output end of the second robotic arm, and a finished product table is provided on one side of the second automatic bending machine through the unloading clamp through the second robotic arm.
[0006] As a further optimization of this utility model, the side wall of the condenser fin feeding conveyor is connected to a positioning conveyor platform. The top rear side of the positioning conveyor platform is provided with a condenser fin positioning line. A second electric cylinder is fixedly installed at the top of the front side wall of the positioning conveyor platform. The output end of the second electric cylinder passes through the front side wall of the positioning conveyor platform and is connected to a push plate that cooperates with the condenser fin positioning line.
[0007] As a further optimization of this utility model, the feeding fixture includes a feeding clamping seat fixedly installed at the output end of the first robotic arm, a first electric cylinder is installed on the top of the feeding clamping seat, and the output end of the first electric cylinder is connected to a feeding clamping plate that cooperates with the feeding clamping seat.
[0008] As a further optimization of this utility model, the unloading fixture includes an unloading clamping seat fixedly installed at the output end of the second robotic arm, a third electric cylinder is installed on the top of the unloading clamping seat, and the output end of the third electric cylinder is fixedly connected to an unloading clamping plate that cooperates with the unloading clamping seat.
[0009] As a further optimization of this utility model, the first automatic bending machine and the second automatic bending machine have the same structure. Both the first automatic bending machine and the second automatic bending machine are slidably connected to an electric slide table on their tops. Transmission boxes are fixedly installed on both sides of the top of the first automatic bending machine and the second automatic bending machine. The input ends of the two transmission boxes are connected to swing cylinders fixedly installed on the side walls of the transmission boxes. The output ends of the two transmission boxes are connected to bending parts that cooperate with the corresponding electric slide tables.
[0010] As a further optimization of this utility model, it also includes a control cabinet, which is electrically connected to the condenser fin feeding conveyor, the second electric cylinder, the positioning conveyor, the first robotic arm, the first electric cylinder, the third electric cylinder, and the swing cylinder.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. This utility model achieves automatic and precise positioning of condenser fins by combining the condenser fin positioning line of the positioning conveyor table with the second electric cylinder push plate; the first / second robotic arm stably clamps the condenser fins by driving the clamps (first electric cylinder and third electric cylinder) with electric cylinders, avoiding deformation caused by manual contact; during the bending stage, the electric slide table works with sensors to finely adjust the position.
[0013] 2. This utility model automates the entire process from condenser fin loading (condenser fin loading conveyor), positioning (second electric cylinder), transfer (first robotic arm) to unloading (second robotic arm), requiring only manual replenishment of condenser fins to be processed and sorting of finished products periodically; at the same time, the movements of the robotic arm and bending machine are coordinated through the control cabinet, avoiding personnel from entering the dangerous processing area and completely avoiding the safety risks of traditional manual operation.
[0014] 3. This utility model, through the linkage of the first robotic arm with the first / second automatic bending machine, can flexibly allocate the feeding task—when one bending machine is processing, the other machine simultaneously completes feeding or waits for material, realizing "dual-machine parallel" production; at the same time, the second robotic arm focuses on unloading, avoiding conflicts between feeding and unloading actions, improving production efficiency compared to the single bending machine mode, and solving the efficiency bottleneck of "processing-waiting" in traditional equipment.

Detailed Implementation
[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0023] Example 1
[0024] like Figures 1-4As shown, an automatic loading and unloading bending machine includes a flow pipe 1. The equipment uses a condenser fin loading conveyor 1 as the loading starting point, which serves as the initial conveying carrier for the condenser fin workpieces. It is horizontally installed on one side of the production area and can stably convey the condenser fins to be processed along a set direction. In order to achieve precise positioning of the condenser fins, a positioning conveyor table 17 is fixedly connected to the side wall of the condenser fin loading conveyor 1 by bolts. The positioning conveyor table 17 is connected to the conveying end of the condenser fin loading conveyor 1, and the condenser fins to be processed can smoothly transition from the condenser fin loading conveyor 1 to the top of the positioning conveyor table 17.
[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a condenser fin positioning line 12 is engraved on the top rear side of the positioning conveyor 17. This positioning line 12 is adapted to the outline of the condenser fins and is used to define the placement position of the condenser fins. At the same time, a second electric cylinder 11 is fixedly installed on the top of the front side wall of the positioning conveyor 17 by a bracket. The output end of the second electric cylinder 11 passes through the front side wall of the positioning conveyor 17 in a horizontal direction and is connected to a push plate (not separately labeled) by a coupling. The rear side of the push plate corresponds to the condenser fin positioning line 12. When the condenser fins are conveyed to the positioning conveyor 17, the second electric cylinder 11 can drive the push plate to move backward, pushing the condenser fins to fit with the condenser fin positioning line 12, completing the precise positioning of the condenser fins and providing a stable reference for subsequent feeding and clamping.
[0026] like Figures 1-6As shown, the feeding system is centered on the first robotic arm 2. The first robotic arm 2 is fixedly installed on a base in the area between the condenser fin feeding conveyor 1 and the subsequent bending equipment. Its output end can rotate and move in multiple dimensions to cover the feeding stations of the positioning conveyor 17, the first automatic bending machine 6, and the second automatic bending machine 8. A feeding clamp is fixedly installed on the output end of the first robotic arm 2 via a flange. This feeding clamp includes a feeding clamping seat 3, a first electric cylinder 4, and a feeding clamping plate 5. The top of the horizontal section of the feeding clamping seat 3 is fixedly connected to the output end of the first robotic arm 2 by bolts. The top of the vertical section of the feeding clamping seat 3 is equipped with the first electric cylinder 4. The output end of the first electric cylinder 4 extends downwards in the vertical direction and is fixedly connected to the top center of the feeding clamping plate 5. The bottom of 5 is parallel to and corresponds to the top of the horizontal section of the feeding clamp 3. When the first robotic arm 2 moves the feeding clamp to above the positioning conveyor table 17, the first electric cylinder 4 extends and drives the feeding clamp 5 to move downward, cooperating with the feeding clamp 3 to clamp the positioned condenser fins. Then the first robotic arm 2 transfers the condenser fins to the processing station of the first automatic bending machine 6 or the second automatic bending machine 8. The first automatic bending machine 6 and the second automatic bending machine 8 are arranged side by side in the horizontal direction. The second automatic bending machine 8 is located on the side of the first automatic bending machine 6 away from the condenser fin feeding conveyor 1. Both are fixed to the ground with anchor bolts, and the height of the processing station is adapted to the clamping height of the feeding clamp, ensuring that the first robotic arm 2 can smoothly complete the feeding and transfer of the condenser fins.
[0027] like Figures 1-4 As shown, the first automatic bending machine 6 and the second automatic bending machine 8 have the same structure. Taking the first automatic bending machine 6 as an example, an electric slide table 13 is installed on its top along the length direction. The top of the slider of the electric slide table 13 can hold the condenser fins to be processed, and the slider can move along the guide rail of the electric slide table 13 to adjust the bending position of the condenser fins. The top two sides of the first automatic bending machine 6 are respectively fixedly installed with brackets, and the two transmission boxes 14 are symmetrically distributed on both sides of the electric slide table 13. A swing cylinder 15 is installed on the outer wall of each transmission box 14. The output shaft of the swing cylinder 15 passes through the side wall of the transmission box 14 and is geared to the internal transmission mechanism. The gearbox 14 is connected to the inner wall output end via a bearing, and the axis of the bending component 18 is parallel to the length direction of the electric slide table 13. The distance between the outer walls of the two bending components 18 is adapted to the bending angle requirement of the condenser fins. When the condenser fins are placed on the slider of the electric slide table 13 by the feeding fixture, the electric slide table 13 drives the condenser fins to move between the two bending components 18. Then, the swing cylinders 15 on both sides are started, and the bending components 18 are driven to swing synchronously through the transmission mechanism inside the gearbox 14 to bend the condenser fins. During the processing, the electric slide table 13 can finely adjust the position of the condenser fins to ensure bending accuracy.
[0028] like Figure 1 , Figure 2 , Figure 4 As shown, the unloading system is centered on the second robotic arm 7. The second robotic arm 7 is fixedly installed on the side of the second automatic bending machine 8 away from the first automatic bending machine 6 via a base. The range of motion of its output end can cover the processing station of the first automatic bending machine 6 and the second automatic bending machine 8 and the finished product table 10. The output end of the second robotic arm 7 is fixedly installed with an unloading fixture via a flange. The unloading fixture includes an unloading clamping seat 9, a third electric cylinder 20 and an unloading clamping plate 19. The structure of the unloading clamping seat 9 is the same as that of the loading clamping seat 3. The top of its horizontal section is fixedly connected to the output end of the second robotic arm 7. The top of the vertical section of the unloading clamping seat 9 is equipped with the third electric cylinder 20. The output end of the third electric cylinder 20 extends downward and is fixedly connected to the top of the unloading clamping plate 19. The unloading clamping plate 19 cooperates with the horizontal section of the unloading clamping seat 9 to clamp the bent finished condenser fins.
[0029] like Figure 1 As shown, the finished product table 10 is located on the side of the second robotic arm 7 away from the second automatic bending machine 8. Its top is covered with an anti-slip rubber pad for placing the bent finished condenser fins. After the first automatic bending machine 6 or the second automatic bending machine 8 completes the bending of the condenser fins, the second robotic arm 7 drives the unloading clamp to move to the processing station. The third electric cylinder 20 extends and drives the unloading clamp 19 to clamp the finished condenser fins, which are then transferred to the finished product table 10 and released to complete the unloading operation.
[0030] like Figure 1 As shown, the equipment also includes a control cabinet 16, which is mounted on the ground next to the equipment via a bracket. The control cabinet 16 integrates a condenser fin PLC controller, relays, a touch screen, and other components. It is electrically connected via cables to the condenser fin feeding conveyor 1, the second electric cylinder 11, the positioning conveyor table 17, the first robotic arm 2, the first electric cylinder 4, the third electric cylinder 20, and the swing cylinder 15, achieving fully automated control of the equipment. During actual operation, the operator sets processing parameters such as bending angle through the touch screen on the control cabinet 16. The feeding frequency is adjusted, and then the system operates in the following logic: the condenser fin feeding conveyor 1 transports the condenser fins to be processed to the positioning conveyor table 17 → the second electric cylinder 11 drives the push plate to position the condenser fins → the first robotic arm 2 drives the feeding fixture to clamp the condenser fins and transfer them to the bending machine → the electric slide table 13 adjusts the position of the condenser fins, and the swing cylinder 15 drives the bending part 18 to complete the bending → the second robotic arm 7 drives the unloading fixture to transfer the finished product to the finished product table 10. The whole process does not require manual intervention, realizing fully automated production of condenser fin bending.
[0031] It should be noted that in use, the operator places the condenser fins to be processed into the condenser fin feeding conveyor 1. The control cabinet 16 starts the conveyor, transporting the condenser fins to the positioning conveyor table 17. After the table sensor detects the condenser fins, the conveyor stops. The second electric cylinder 11 drives the push plate to push the condenser fins until the condenser fins are aligned with the condenser fin positioning line 12 and the positioning is completed. After the push plate resets, it waits for feeding. The control cabinet 16 instructs the first robotic arm 2 to move the feeding clamp to the top of the positioning table. The first electric cylinder 4 drives the feeding clamp 5 to move down, cooperating with the feeding clamp seat 3 to clamp the condenser fins. The robotic arm transfers the condenser fins to the idle first condenser fin and second automatic bending machine, aligns the slider of the electric slide table 13 and lowers the condenser fins. The clamp moves up and resets. The robotic arm... Waiting for the next task, the electric slide table 13 moves the condenser fins to the bending part 18. After the sensor confirms the position, the slide table stops. The control cabinet 16 starts the swing cylinders 15 on both sides, which drive the bending part 18 to swing at a preset angle through the transmission box 14, squeezing the condenser fins to complete the bending. If fine adjustment is needed, the slide table moves slightly. After bending, the rollers return to their original position, and the slide table carries the finished product to the unloading station. The second robotic arm 7 drives the unloading clamp to the bending machine. The third electric cylinder 20 drives the unloading clamp plate 19 and the unloading clamp seat 9 to clamp the finished product, which is then transferred to the finished product table 10 and placed down. The robotic arm returns to its original position. The operator regularly sorts the finished products. The control cabinet 16 receives sensor signals from each component and coordinates actions to avoid conflicts. It flexibly allocates robotic arms to feed materials to the double bending machine, enabling the two machines to operate in parallel. In case of abnormality, it alarms and stops the machine and displays the fault, ensuring efficient and accurate processing.
[0032] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
