Description

Technical Field

[0001] This utility model relates to the field of production line pressing equipment technology, specifically to an actuator cover pressing structure. Background Technology

[0002] Using actuators to replace manual repetitive operations on continuous production lines can greatly improve production efficiency and reduce operational errors. Through program control, the motion parameters of each batch of products are completely consistent, reducing quality fluctuations caused by human error. In the production line process, existing equipment uses vacuum suction to pick up the top cover, and then uses a robotic arm with displacement sensors to adjust the pressing position. Pressure sensors are configured to press the top cover during the pressing process. If the top cover pressing fails, the defective product can only flow to the next mechanism to distinguish between NG and OK status. NG products cannot be directly removed after pressing, occupying production stations and easily causing misalignment of serial numbers in continuous production. To address this, we propose an actuator top cover pressing structure. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides an actuator cover pressing structure, including a fixed frame, a dual-axis driven robotic arm mechanism is provided on the top of the fixed frame, a pressing cylinder is fixedly connected to the pressing rod in the robotic arm mechanism, the pressing cylinder is fixed on the pressing mechanism, and the pressing mechanism is provided with a clamping mechanism for gripping NG products.

[0004] In some embodiments, the pressing mechanism includes a top support plate that provides fixed support for the pressing cylinder, and guide rods are provided at the four bottom corners of the top support plate, with the bottom ends of the guide rods fixed to the four top corners of the upper cover suction cup.

[0005] In some embodiments, the clamping mechanism includes a sliding plate slidably connected to a guide rod, the top of the sliding plate being fixedly connected to the output end of a pressing cylinder, the bottom of the sliding plate being fixedly connected to a clamping cylinder, and the output end of the clamping cylinder being fixedly connected to a clamping slider.

[0006] In some embodiments, the bottom of the clamping slider is provided with a clamping plate, and the clamping plate is provided with an adjustment mechanism for adapting to the structure of products of different sizes, and the adjustment mechanism is provided with grippers.

[0007] In some embodiments, the adjusting mechanism includes a limiting post fixedly sleeved on the clamping plate, the limiting post being slidably connected to the gripper, and the gripper being distributed on both sides of the clamping plate. A double-ended stud is rotatably connected to the clamping plate, and an adjusting sleeve is threadedly connected to the double-ended stud. The adjusting sleeve is fixedly sleeved in the gripper.

[0008] In some embodiments, a worm gear assembly is fitted onto the double-ended stud, and the worm wheel in the worm gear assembly is fixedly sleeved on the double-ended stud. The worm in the worm gear assembly is fixedly connected to the output end of an adjusting motor, and the adjusting motor is fixed on a clamping plate.

[0009] This utility model has at least the following beneficial effects:

[0010] 1. This utility model uses a pressing mechanism consisting of a top support plate, guide rod, and top cover suction cup mounted on a robotic arm. The robotic arm swings in conjunction with the top cover suction cup to pick up the top cover to be pressed. Then, the pressing mechanism is driven by a downward push rod in the robotic arm to press down and achieve pressing. Simultaneously, a sliding plate slidably connected to the guide rod is used to mount a clamping cylinder. When a product is determined to be defective, the clamping cylinder's height is adjusted in conjunction with the downward push cylinder. At the same time, the clamping cylinder drives the clamping slider and clamping plate to move closer together, using the grippers on both sides to pick up the defective product. This avoids occupying production workstations and reduces the risk of misalignment in the sequence numbers of continuously produced products.

[0011] 2. This utility model adjusts the rotation of the worm in the worm gear assembly driven by the motor, which in turn drives the double-ended stud to rotate. During the rotation of the double-ended stud, the screws on both sides move closer or further apart synchronously through the threaded engagement with the adjusting sleeve, forming an adjustable gripper structure that can be adapted to products of different sizes, thus improving the overall applicability.

Detailed Implementation

[0017] 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.

[0018] Example 1:

[0019] Please see Figure 1-2 This utility model provides a technical solution: an actuator cover pressing structure, including a fixed frame 1, a dual-axis driven robotic arm mechanism 2 is set on the top of the fixed frame 1, a pressing cylinder 3 is fixedly connected to the pressing push rod in the robotic arm mechanism 2, the pressing cylinder 3 is fixed on the pressing mechanism 4, and the pressing mechanism 4 is provided with a clamping mechanism 5 for gripping NG products; the fixed frame 1 serves as the supporting base of the overall structure, ensuring the stable operation of components such as the robotic arm mechanism 2 and the pressing mechanism 4, and avoiding vibration or displacement affecting accuracy. The robotic arm mechanism 2 controls the movement of the pressing mechanism 4 through dual-axis drive to ensure accurate alignment between the cover and the product. The pressing push rod provides vertical pressing force to complete the pressing action of the cover. When sorting NG products, the height of the clamping mechanism 5 is adjusted in conjunction with the pressing cylinder 3 to ensure stable gripping. The whole process is completed automatically, reducing manual intervention and improving the yield rate.

[0020] Example 2:

[0021] Please see Figure 1-2 The pressing mechanism 4 includes a top support plate 41 that fixes and supports the pressing cylinder 3. Guide rods 42 are provided at the four bottom corners of the top support plate 41. The bottom ends of the guide rods 42 are fixed to the four top corners of the upper cover suction cup 43. The pressing mechanism 4 uses the top support plate 41 as the main support frame to ensure the installation of the pressing cylinder 3 is stable and to avoid displacement or vibration caused by uneven force during the pressing process. The guide rods 42 at the four corners provide uniform guiding support so that the upper cover suction cup 43 remains horizontal when moving vertically, preventing poor pressing caused by tilting. At the same time, the four corner supports distribute the force to avoid deformation of the mechanism due to single-point overload and extend the service life. The pressing mechanism 4 provides vertical pressing force through the pressing push rod in the robotic arm mechanism 2.

[0022] Example 3:

[0023] Please see Figure 1-2The clamping mechanism 5 includes a sliding plate 51 slidably connected to the guide rod 42. The top of the sliding plate 51 is fixedly connected to the output end of the pressing cylinder 3, and the bottom of the sliding plate 51 is fixedly connected to a clamping cylinder 52. The output end of the clamping cylinder 52 is fixedly connected to a clamping slider 53, and the bottom of the clamping slider 53 is provided with a clamping plate 54. The clamping plate 54 is provided with an adjustment mechanism 55 for adapting to products of different sizes and structures, and the adjustment mechanism 55 is provided with grippers 56. When a product is determined to be NG (not good), the clamping cylinder 52 is adjusted in conjunction with the pressing cylinder 3 to adjust its height. At the same time, the clamping cylinder 52 drives the clamping slider 53 and the clamping plate 54 to move closer to each other, and the grippers 56 on both sides are used to pick up the NG product, avoiding the occupation of the production station and reducing the workload. When the serial numbers of continuously produced products are misaligned, the downward pressure cylinder 3 drives the sliding plate 51 to move up and down along the guide rod 42, which can precisely adjust the clamping height to adapt to NG products of different thicknesses, avoiding interference with the normal production process. After an NG product is identified, the clamping cylinder 52 immediately acts, grabbing and removing it through the gripper 56 without stopping the production line, ensuring the continuous production rhythm. At the same time, the robotic arm mechanism 2 works in coordination, directly removing the NG product after grabbing it, avoiding production line stagnation caused by manual intervention, and reducing the risk of production serial number confusion. The sliding plate 51 guided by the guide rod 42 can ensure that the clamping mechanism 5 does not shake when moving vertically. In conjunction with the clamping cylinder 52, the slider directly drives the gripper 56, resulting in a short power transmission path, fast response speed, and stable and controllable clamping force.

[0024] Example 4:

[0025] Please see Figure 1-2The adjusting mechanism 55 includes a limiting post 551 fixedly sleeved on the clamping plate 54. The limiting post 551 is slidably connected to the gripper 56, and the gripper 56 is distributed on both sides of the clamping plate 54. A double-ended stud 552 is rotatably connected to the clamping plate 54. An adjusting sleeve 553 is threadedly connected to the double-ended stud 552 and is fixedly sleeved in the gripper 56. A worm gear assembly 554 is fitted onto the double-ended stud 552, and the worm gear in the worm gear assembly 554 is fixedly sleeved on the double-ended stud 552. The worm in the worm gear assembly 554 is fixedly connected to the output end of the adjusting motor 555. The worm gear has a self-locking characteristic to prevent the gripper 56 from shifting due to vibration or external force during clamping, ensuring clamping stability. The adjusting motor 555 is fixed on the clamping plate 54. In use, the adjusting motor 555 drives the worm gear assembly 554. The worm gear rotates, which in turn drives the double-ended stud 552 to rotate via the worm wheel. During the rotation of the double-ended stud 552, it can drive the jaws 56 on both sides to move closer or further away synchronously through the threaded engagement with the adjusting sleeve 553, forming an adjustable jaw 56 structure that can adapt to products of different sizes, improving overall applicability. The left and right thread design of the double-ended stud 552 enables the jaws 56 on both sides to move completely synchronously and symmetrically, avoiding damage to the product due to off-center load. The adjusting motor 555 drives the worm gear, and the motor angle can be controlled by the program to achieve stepless precision adjustment of the distance between the jaws 56, adapting to various sizes. With the help of the limit post 551 for guidance, it ensures that the jaws 56 move linearly without deflection, which is especially suitable for precision assembly scenarios with high alignment requirements. The worm wheel and worm gear assembly 554 and the double-ended stud 552 are built into the clamping plate 54, saving space and avoiding external interference.

[0026] Example 5:

[0027] Please see Figure 3-4This utility model provides a technical solution: an actuator cover press-fit structure, including a fixed frame 1, a dual-axis driven robotic arm mechanism 2 is provided on the top of the fixed frame 1, a pressing cylinder 3 is fixedly connected to the pressing push rod in the robotic arm mechanism 2, the pressing cylinder 3 is fixed on the press-fit mechanism 4, and the press-fit mechanism 4 is provided with a clamping mechanism 5 for clamping NG products; based on the above structure, a connecting frame 101, a clamping member 102, a pressure spring 103 and a locking cylinder 104 are added, the connecting frame 101... A clamping member 102 is slidably connected to a connecting frame 101, fixed to one side of the gripper 56. A pressure spring 103 is provided between the clamping member 102 and the connecting frame 101. A locking cylinder 104 is provided on the side of the connecting frame 101 away from the clamping member 102. The output end of the locking cylinder 104 passes through the connecting frame 101 and is fixedly connected to the top piece used to press the clamping member 102. During the capping process, the downward push rod in the robotic arm mechanism 2 drives the downward cylinder 3 and the pressing mechanism 4 to move downward, picking up the upper cover suction cup 43. When the cover is placed on the product and the product is deemed OK, the push rod is reset and moved upward without further action. When the product is deemed NG, the press cylinder 3 drives the clamping cylinder 52 to move downward to adjust the height of the clamping component 102. Then, the clamping cylinder 52, together with the clamping sliders 53 on both sides and the clamping component 102, moves closer to each other to clamp the product. Afterward, the robotic arm mechanism 2 moves the NG product off the production line. During the clamping process, as the clamping component 102 approaches the product, the pressure spring 103 first provides elastic clamping force to prevent the product from being damaged by pressure. In the initial clamping stage, the elastic deformation of the pressure spring 103 provides flexible clamping force to avoid damage to the NG product due to rigid impact, which is especially suitable for fragile or precision parts. Then, the locking cylinder 104 moves the top plate forward to limit the backward movement of the clamping component 102. After clamping, the locking cylinder 104 pushes the top plate to fix the clamping component 102, switching to rigid mode to ensure clamping stability during the transfer process and prevent the product from falling off. Flexible clamping reduces the probability of secondary damage to NG products and reduces material waste.
