Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger production equipment, and in particular to an automatic motherboard mounting device. Background Technology

[0002] Currently, heat exchangers, as important industrial components, are typically assembled using specialized assembly equipment. During heat exchanger assembly, the mainboard is a key component, usually requiring one to be installed on each side. In existing technology, the mainboards are generally installed manually. Specifically, when the assembly equipment reaches a specific station, the operator manually places the left and right mainboards onto their corresponding mounting fixtures.

[0003] However, this manual operation method has significant technical drawbacks. First, for production safety reasons, the entire assembly equipment must be stopped when operators manually place the motherboard to avoid mechanical injury accidents. This "human-machine interlock" safety mechanism directly leads to frequent equipment start-ups and shutdowns, resulting in an intermittent work pattern of "manual operation - equipment shutdown and waiting, equipment operation - manual waiting." Second, this work pattern completely includes manual operation time within the total cycle time of the equipment. Each manual loading causes an interruption in the overall operation of the equipment, severely restricting the improvement of equipment assembly efficiency and becoming a bottleneck for improving production efficiency. This efficiency loss is particularly significant during mass production.

[0004] Therefore, there is an urgent need in this field for a technical solution that can overcome the above-mentioned defects, and effectively shorten the equipment assembly cycle and improve overall production efficiency while ensuring the safety of operators. Utility Model Content

[0005] The purpose of this invention is to provide an automatic motherboard loading device. By setting up a translation drive mechanism, this invention realizes the parallel operation of manual operation and automated equipment operation, which significantly improves equipment utilization and fundamentally eliminates equipment downtime caused by waiting for manual loading, thereby greatly shortening the overall operating cycle of the equipment and improving assembly efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an automatic motherboard mounting device for heat exchanger assembly equipment, comprising:

[0007] Support frame;

[0008] A placement rack is fixedly connected to the support base frame, and a placement fixture for supporting the motherboard is provided on the placement rack;

[0009] A translation drive mechanism is installed on the placement frame and is used to drive the placement fixture to reciprocate between the manual placement position and the mechanical gripping position on the placement frame;

[0010] A gripping mechanism is provided on one side of the placement fixture and is used to grip the motherboard on the placement fixture as it moves to the mechanical gripping position.

[0011] Furthermore, the translation drive mechanism includes a drive motor, a linear guide rail, and a slider. The linear guide rail is fixedly connected to the placement frame, and the placement fixture is slidably connected to the linear guide rail via the slider. The drive motor is mounted on the placement fixture and is used to transport the placement fixture to the mechanical gripping position.

[0012] Furthermore, the output end of the drive motor is connected to a drive shaft, on which a gear is mounted, and the gear meshes with a rack fixedly connected to the mounting frame.

[0013] Furthermore, the gripping mechanism includes a frame, grippers, and a rodless cylinder. The frame is located at the rear end of the placement frame, and the rodless cylinder is fixedly connected to the frame. The output end of the rodless cylinder is mutually driven and connected to the grippers.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, by setting up a translation drive mechanism, realizes parallel operation of manual and automated equipment operation, significantly improving equipment utilization. This application uses a translation drive mechanism composed of a drive motor, linear guide rail, and slider to drive the placement fixture to move between the "manual placement position" and the "mechanical gripping position." When the placement fixture is in the "manual placement position" on the left, the operator can safely perform the loading operation; simultaneously, the assembly of other parts of the equipment can be carried out synchronously in the "mechanical gripping position" on the right, with the gripping mechanism completing the gripping of the already positioned motherboard. This spatial and temporal separation design ensures that the time-consuming manual loading action no longer occupies the core assembly time of the equipment, changing the original serial operation mode to a parallel operation mode, fundamentally eliminating equipment downtime caused by waiting for manual loading, thereby significantly shortening the overall operating cycle of the equipment and improving assembly efficiency.

[0016] 2. This utility model utilizes a gripping mechanism consisting of a frame, a rodless cylinder, and grippers, with the rodless cylinder driving the grippers to perform the gripping action. This structure is simple and reliable, and the rodless cylinder provides smooth linear motion, ensuring the positioning accuracy and operational stability of the grippers when gripping the motherboard, thus contributing to the quality of the final assembled product.

[0023] Example 1:

[0024] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is an enlarged structural schematic diagram of the drive motor in this utility model, as shown below. Figure 1 and Figure 2 As shown, this embodiment provides an automatic motherboard loading device, including: a support base frame 1, a placement frame 10, a placement fixture 2, a translation drive mechanism, and a gripping mechanism. The support base frame 1, serving as the foundation component of the entire device, is welded from shaped steel or steel plates. Its bottom can be fixedly installed on the workbench or ground of the heat exchanger assembly equipment using anchor bolts or other connectors. Its main function is to provide stable support, ensuring sufficient rigidity and stability of the upper mechanisms during operation, preventing vibration or displacement that could affect loading accuracy. The placement frame 10 is fixedly installed on the support base frame 1, forming the mounting base for the translation drive mechanism and the placement fixture 2, and providing span support and a mounting surface for the linear guide rail 4 above it.

[0025] The translation drive mechanism in this invention is mounted on the placement frame 10. Its core function is to drive the placement fixture 2 to perform precise reciprocating linear motion between the manual placement position (located on the left side of the equipment for easy operator access) and the mechanical gripping position (located on the right side of the equipment). This mechanism mainly includes a drive motor 3, which serves as the core power source; in this embodiment, a servo motor or stepper motor is preferably used. It is started, stopped, and positioned by commands from a precision control system (not shown in the figure, such as a PLC), enabling precise control of the movement and stopping position of the placement fixture 2 to ensure it accurately reaches the manual placement position or the mechanical gripping position.

[0026] In this invention, the linear guide rail 4 is fixedly installed on the placement frame 10. The slider 7 and the linear guide rail 4 form a sliding pair. The drive motor 3 converts the rotational motion into linear motion through the gear 302 and rack 11 transmission mechanism (in this invention, a drive shaft 301 is connected to the output end of the drive motor 3, and a gear 302 is installed on the drive shaft 301. The gear 302 meshes with the rack 11 fixedly connected to the placement frame 10). This drives the placement fixture 2 connected to the slider 7 to slide smoothly along the guide rail 4.

[0027] In this invention, the placement fixture 2 is slidably connected to the linear guide rail 4 via the slider 7 and is driven by a translation drive mechanism. Its function is to support and position the main board 9. The upper surface of the placement fixture 2 is provided with a contour groove that matches the shape of the main board 9 to be loaded, ensuring that the operator can quickly and accurately place the main board 9 in the predetermined position and prevent shaking or displacement during movement. To further enhance the flexible production capability of the equipment, the placement fixture 2 can also be designed as a quick-change type, fixed to the connecting plate of the slider 7 by positioning pins and quick-clamp bolts, so that when changing product models, a matching special fixture can be quickly replaced.

[0028] The gripping mechanism in this invention is located at the end of the moving path of the placement fixture 2 (i.e., the mechanical gripping position). Its task is to automatically grip the motherboard 9 and transfer it to the next assembly position after the placement fixture 2 carries the motherboard 9 to this position. This mechanism mainly includes a frame 8, a rodless cylinder 6, and gripper claws. The frame 8 serves as the mounting base for the gripping mechanism, and the cylinder body of the rodless cylinder 6 is horizontally fixed to the frame 8 by bolts or other means. The rodless cylinder 6 has the advantages of compact structure, large stroke, and strong load capacity, and its slider 7 directly serves as the driving end. In this embodiment, it acts as a lifting drive component, responsible for providing linear motion in the vertical direction. The gripper claw 5 is a pneumatic parallel finger gripper 5, which is driven by a cylinder to open and close, directly performing the gripping and releasing action of the motherboard 9. The gripping surface of the gripper claw 5 can also be inlaid with soft materials such as polyurethane or designed with a contoured structure to provide sufficient gripping force while avoiding scratches or indentations on the surface of the motherboard 9. The action of the rodless cylinder 6 can directly drive the gripper 5 to perform lifting and lowering movements. Specifically, the rodless cylinder 6 drives the gripper 5 to descend to the gripping height, and then the gripper 5 cylinder action causes the gripper 5 to close and clamp the motherboard 9. Subsequently, the rodless cylinder 6 drives the gripper 5, which has gripped the motherboard 9, to rise to a safe height. Finally, the gripper 5 is moved above the final assembly position and released by other transfer mechanisms (such as another horizontal motion module, not shown in the figure).

[0029] The working process of this utility model is as follows:

[0030] 1. After the system starts, the drive motor 3 of the translation drive mechanism is controlled to move the placement fixture 2 to the manual placement position (left side of the equipment). At this time, the operator accurately places a motherboard 9 into the positioning mechanism of the placement fixture 2.

[0031] 2. After the operator completes the loading, a completion signal is issued (e.g., by pressing a button or through automatic detection by a sensor). Upon receiving the signal, the control system instructs the drive motor 3 to start, which in turn drives the slider 7 and the connected placement fixture 2 via the transmission mechanism, smoothly moving along the linear guide rail 4 from the manual placement position on the left to the mechanical gripping position on the right. The precise positioning function of the servo motor ensures that the placement fixture 2 can accurately stop at the predetermined position, so that the main board 9 is exactly below the gripper 5.

[0032] 3. Once the placement fixture 2, carrying the motherboard 9, reaches the mechanical gripping position and is precisely positioned, the rodless cylinder 6 drives the gripper 5 to descend from the standby height to the gripping height. Next, the cylinder controlling the opening and closing of the gripper 5 actuates, causing the gripper 5 to close and firmly hold the motherboard 9 on the placement fixture 2. Then, the rodless cylinder 6 actuates again, driving the gripper 5, holding the motherboard 9, to rise back to the lifting height, separating the motherboard 9 from the placement fixture 2. Finally, the gripping mechanism as a whole, or via a subsequent transfer device, transports the motherboard 9 to the next station on the heat exchanger assembly line for installation. Simultaneously, during the gripping and transfer actions of the gripper 5, the drive motor 3 can immediately drive the unloaded empty placement fixture 2 back to the manual placement position, allowing the operator to perform the loading operation again. This achieves complete parallelization of the manual loading and automatic gripping and assembly processes.

[0033] 4. The above steps are repeated, thereby continuously supplying motherboard 9 to the assembly equipment, greatly reducing equipment waiting time, shortening the production cycle to be determined only by the time of automatic gripping and transfer actions, and significantly improving overall production efficiency.

[0034] Through the above methods, this utility model transforms the manual operation and automatic operation of equipment, which originally had to be carried out in sequence, into parallel operation, and overcomes the bottleneck that restricts the improvement of equipment efficiency while ensuring the absolute safety of operators.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
