Description

Technical Field

[0001] This utility model relates to the field of automatic assembly line technology for electronic control units, specifically a stacking structure for a feeding device for an automatic assembly line of electronic control units. Background Technology

[0002] The electronic control unit (ECU) automated assembly line is an integrated system that realizes automated material handling, precision assembly, multi-dimensional inspection, post-processing, and production control. Its core objectives are to ensure assembly accuracy, improve production efficiency, reduce manual intervention, and meet the stringent reliability and stability requirements of the ECU. The ECU automated assembly line consists of a feeding device and supply system, assembly process modules, a full-process inspection and testing system, a post-processing and intelligent packaging system, and a central control and production management system.

[0003] In the current technology, the feeding device and feeding system consists of a material warehouse, a palletizing structure, a material distributor, a material transport channel, a positioning and sorting unit, etc. When used for PCB board palletizing, the cylinder in the palletizing structure needs to drive the clamping plate to hold the PCB board, and then perform the moving and palletizing operations. In practical use, the produced PCBs vary in thickness and size. The clamping force of the cylinder-driven clamping plate depends on the air pressure or mechanical limit, and cannot be dynamically and adaptively adjusted according to the thickness of the PCB. For thin PCBs, the fixed clamping force will exceed the board's bearing limit, causing the board to bend, solder joints to fall off, or even directly crack the substrate. For thick PCBs, if the clamping force is insufficient, slippage or falling off is likely to occur during the stacking process, causing collision damage to the board. Therefore, a stacking structure for a feeding device for an automatic assembly line of electronic control unit is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a palletizing structure for a feeding device in an automatic assembly line for electronic control units. This structure features dynamic adaptive adjustment of the clamping force, solving the problem that PCBs produced vary in thickness and size. Traditional pneumatic clamping relies on air pressure or mechanical limits for force adjustment, making dynamic adaptive adjustment based on PCB thickness impossible. For thin PCBs, the fixed clamping force exceeds the board's tolerance limit, leading to bending, solder joint detachment, or even direct cracking of the substrate. For thick PCBs, insufficient clamping force can cause slippage or detachment during palletizing, resulting in collision damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a palletizing structure for a feeding device for an automatic assembly line of an electronic control unit, including a mounting platform disposed on the feeding device, wherein two positioning clamps for clamping PCB boards are disposed on the mounting platform; The mounting platform is provided with gears for linking two positioning clamps, and the two positioning clamps are symmetrical about the central axis of the gears. The mounting platform is provided with elastic components for controlling the two positioning clamps to dynamically clamp to the opposite side. The mounting platform is provided with drive components for controlling the two positioning clamps to open. The positioning fixture includes a clamping plate, and an L-shaped rack that meshes with a gear is fixedly connected to the top of the clamping plate, and the L-shaped rack is slidably mounted on the mounting table. The elastic component includes a guide rod fixedly mounted on the mounting platform, with one end of the guide rod passing through the end of the L-shaped rack. A spring is sleeved on the guide rod, and both ends of the spring are fixedly connected to the end of the L-shaped rack and the protrusion of the mounting platform, respectively. The driving component includes an electric push rod fixedly mounted on the mounting platform. The telescopic end of the electric push rod is fixedly connected to a pressing component, and one side of the pressing component is in contact with an L-shaped rack.

[0006] Furthermore, a bottom hook for supporting the PCB board is fixedly installed on the clamping plate, and the slope of the bottom hook is thirty degrees. A T-shaped part is fixedly installed on the top of the clamping plate.

[0007] Furthermore, the mounting platform includes a mounting frame and a support platform, and the mounting frame and the support platform are an integral structure. Two L-shaped sides symmetrical about the central axis of the gear are fixedly mounted on the support platform. The gear is rotatably mounted at the center of the support platform, and the two L-shaped racks are located between the two L-shaped sides.

[0008] Furthermore, the two elastic components are symmetrically distributed around the central axis of the gear, and the T-shaped part is slidably installed in the gap between the mounting frame and the support platform.

[0009] Furthermore, the extrusion component includes a base and a rubber block, the rubber block is fixedly connected to the base and contacts the L-shaped rack, and one side of the base is fixedly connected to the telescopic end of the electric push rod.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The stacking structure of the feeding device for the automatic assembly line of the electronic control unit uses the flexible elastic force of the spring to drive the two positioning clamps to move adaptively to the opposite side, control the two clamping plates to close, thereby adaptively and flexibly clamping the PCB board, avoiding excessive clamping force that could cause the board to bend. In conjunction with the bottom hook on the clamping plate, the PCB board is lifted to prevent thick boards from slipping due to gravity. 2. The stacking structure of the feeding device for the automatic assembly line of the electronic control unit ensures that the two clamping plates open and close synchronously through gears and two centrally symmetrical L-shaped racks, avoiding PCB board clamping deviation. In addition, the lifting of the bottom hook and the sliding limit of the T-shaped part further reduce the board shaking during the stacking process. 3. The electronic control unit uses a palletizing structure for the feeding device in the automatic assembly line, and uses an electric push rod instead of a cylinder for higher control precision. The rubber block of the extruded part avoids hard contact wear on the L-shaped rack, extending the service life of the structure and reducing the noise generated by rigid contact.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please refer to Figure 1-4 The palletizing structure of the feeding device for an automatic assembly line of an electronic control unit in this embodiment includes a mounting platform 1 set on the feeding device, and two positioning clamps 2 for clamping PCB boards are provided on the mounting platform 1. The mounting platform 1 is provided with a gear 3 for linking two positioning clamps 2, and the two positioning clamps 2 are symmetrical about the central axis of the gear 3. The mounting platform 1 is provided with an elastic component 4 for controlling the two positioning clamps 2 to dynamically clamp to the opposite side. The mounting platform 1 is provided with a drive component 5 for controlling the two positioning clamps 2 to open. The positioning fixture 2 includes a clamping plate 21, and an L-shaped rack 22 that meshes with the gear 3 is fixedly connected to the top of the clamping plate 21. The L-shaped rack 22 is slidably mounted on the mounting table 1. The elastic component 4 includes a guide rod 41 fixedly installed on the mounting platform 1, with one end of the guide rod 41 passing through the end of the L-shaped rack 22. A spring 42 is sleeved on the guide rod 41, and both ends of the spring 42 are fixedly connected to the end of the L-shaped rack 22 and the protrusion of the mounting platform 1, respectively. The drive component 5 includes an electric push rod 51 fixedly mounted on the mounting platform 1. The telescopic end of the electric push rod 51 is fixedly connected to an extrusion member 52, and one side of the extrusion member 52 is in contact with the L-shaped rack 22.

[0015] In addition, the mounting platform 1 includes a mounting frame 11 and a support platform 12, and the mounting frame 11 and the support platform 12 are an integral structure. Two L-shaped sides 121 symmetrical about the central axis of the gear 3 are fixedly mounted on the support platform 12. The gear 3 is rotatably mounted at the center of the support platform 12. The two L-shaped racks 22 are located between the two L-shaped sides 121. The integral structure avoids splicing gaps and provides a unified mounting reference for the gear 3, the L-shaped racks 22 and the elastic component 4. The two L-shaped sides 121 are symmetrical about the central axis of the gear 3, which limits the sliding range of the L-shaped racks 22 and prevents the racks from sliding excessively and disengaging from the gear 3.

[0016] It should be noted that the extrusion component 52 includes a base and a rubber block. The rubber block is fixedly connected to the base and contacts the L-shaped rack 22. One side of the base is fixedly connected to the telescopic end of the electric push rod 51. The rubber block replaces the hard metal contact and there is no rigid friction when it contacts the L-shaped rack 22. This not only protects the rack but also reduces the noise generated by rigid friction.

[0017] Using the above technical solution, the telescopic end of the electric push rod 51 extends at a constant speed, pushing the extrusion piece 52 to squeeze the L-shaped rack 22. The L-shaped rack 22 slides away from the gear 3 along the guide rod 41, while compressing the spring 42. One side of the L-shaped rack 22 drives the gear 3 to rotate clockwise, and the gear 3 then drives the other side of the L-shaped rack 22 to slide in the opposite direction. Finally, the two clamping plates 21 open to both sides synchronously, with the opening distance greater than the maximum width of the PCB board to be loaded. The electric push rod 51 retracts at a constant speed, and the extrusion piece 52 gradually detaches from the L-shaped rack 22. The spring 42 loses the external extrusion force and elastically resets along the direction of the guide rod 41, pulling the two L-shaped racks 22 to slide towards the center of the gear 3. The two clamping plates 21 move towards the PCB board synchronously with the L-shaped racks 22 until the inner side of the clamping plates 21 contacts the two edges of the PCB board, thereby achieving adaptive flexible clamping of the PCB board.

[0018] Example 2: Please refer to Figure 1-4Based on Embodiment 1, a bottom hook 211 for supporting the PCB board is fixedly installed on the clamping plate 21, and the slope of the bottom hook 211 is 30 degrees. A T-shaped part 212 is fixedly installed on the top of the clamping plate 21. The 30-degree slope of the bottom hook 211 guides the PCB board to slide automatically between the two bottom hooks 211. The board can also be stably fixed by the bottom hook 211, and there is no risk of falling off during movement. The clamping plate 21 is limited to sliding only in a direction parallel to the side of the PCB board to avoid the clamping plate 21 shifting up and down, and to ensure that the clamping surface of the clamping plate 21 is always perpendicular to the edge of the PCB board, without tilting or pressure damage.

[0019] Among them, the two elastic components 4 are symmetrically distributed around the central axis of the gear 3, and the T-shaped part 212 is slidably installed in the gap between the mounting frame 11 and the support platform 12. The two elastic components 4 are symmetrical along the central axis of the gear 3, and the stiffness coefficient and preload of the springs 42 on both sides are completely consistent, ensuring that the clamping force of the clamping plate 21 on the PCB board is equal on both sides.

[0020] Using the above technical solution, the bottom hook 211 moves synchronously with the clamping plate 21, and its 30-degree inclined surface faces the feeding channel, which facilitates the PCB board to slide in. The bottom of the PCB board falls between the two bottom hooks 211, and the bottom hooks 211 hook the two sides of the PCB board.

[0021] The working principle of the above embodiments is as follows: In the stacking structure of the feeding device for the automatic assembly line of the electronic control unit, the electric push rod 51 is in a fully retracted state during use. The extrusion part 52 is not in contact with the L-shaped rack 22. The spring 42 is not subjected to additional extrusion. It only pulls the two L-shaped racks 22 toward the center of the gear 3 by the pre-tightening force, which drives the two clamping plates 21 to a slightly closed preparatory state. The bottom hook part 211 and the T-shaped part 212 of the positioning fixture 2 are both in the initial position, waiting for the PCB board to be fed. After the PCB board is loaded, the telescopic end of the electric push rod 51 extends at a constant speed, pushing the extrusion piece 52 to extrude the L-shaped rack 22. The L-shaped rack 22 slides along the guide rod 41 away from the gear 3, while compressing the spring 42. One side of the L-shaped rack 22 drives the gear 3 to rotate clockwise, and the gear 3 then drives the other side of the L-shaped rack 22 to slide in the opposite direction. Finally, the two clamping plates 21 open to both sides in sync, and the opening gap is greater than the maximum width of the PCB board to be loaded. At this time, the bottom hook part 211 moves synchronously with the clamping plate 21, and its 30-degree inclined surface faces the loading channel, which facilitates the PCB board to slide in. The bottom of the PCB board falls between the two bottom hook parts 211, and the bottom hook parts 211 hook the two sides of the PCB board. The electric push rod 51 retracts at a constant speed, the extrusion piece 52 gradually disengages from the L-shaped rack 22, the spring 42 loses the external extrusion force and elastically resets along the direction of the guide rod 41, pulling the two L-shaped racks 22 to slide towards the center of the gear 3, and the two clamping plates 21 move towards the PCB board synchronously with the L-shaped racks 22 until the inner side of the clamping plates 21 contacts the two side edges of the PCB board, thereby achieving adaptive flexible clamping of the PCB board.
