Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, and in particular to an automatic assembly device for plastic-coated terminals. Background Technology

[0002] In the field of electronics manufacturing, plastic-coated terminals are an important electrical connection component and are widely used in various electronic products, such as circuit boards and electrical equipment. Their assembly quality directly affects the electrical performance and stability of the products.

[0003] Traditional assembly of plastic-coated terminals relies primarily on manual operation, which has several drawbacks. Firstly, manual assembly is inefficient. With the continuous growth in demand for electronic products and the gradual expansion of production scale, traditional manual assembly struggles to meet the increasing production speed requirements, becoming a bottleneck restricting the improvement of enterprise production efficiency. Secondly, manual operation has limited precision and stability, and is easily affected by factors such as fatigue and emotional state, leading to quality problems such as positional deviations and insecure crimping of the plastic-coated terminals during assembly. This, in turn, affects the overall quality and reliability of the product, increasing the defect rate and after-sales maintenance costs.

[0004] Meanwhile, the pace of electronic product upgrades is accelerating, and the variety of products is increasing. Different models of products use different specifications of plastic-coated terminals, requiring assembly equipment to have greater versatility and flexibility to quickly adapt to the assembly needs of products with varying specifications. However, traditional assembly processes and simple tools are insufficient to achieve this, often requiring extensive tooling and fixture changes and manual adjustments for different products, further reducing production efficiency and increasing production and time costs. Therefore, we propose an automated assembly device for plastic-coated terminals. Utility Model Content

[0005] This utility model is an automatic assembly device for plastic-coated terminals, proposed to overcome the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic assembly device for plastic-coated terminals includes a base plate, a support frame on the upper side of the base plate, an electrical control box on the right side of the support frame, a movable gripper assembly on the front side of the support frame, a pressing component on one side of the movable gripper assembly, a vibratory feeding assembly on the rear side of the base plate, a pushing component on one side of the vibratory feeding assembly, and a product placement section on the upper side of the base plate.

[0008] Preferably, the movable gripper assembly includes an electric slide rail, which is disposed on one side of the support frame. A connector is disposed on one side of the electric slide rail, and a cylinder is disposed on one side of the connector. A mounting plate is disposed on the shaft end of the cylinder, and a second cylinder is disposed on one side of the mounting plate. A gripper is disposed on the shaft end of the second cylinder.

[0009] Preferably, the pressing assembly includes a cylinder three, which is disposed on the upper side of the mounting plate. A guide rail is provided on one side of the mounting plate, and a pressing block is provided at the shaft end of the cylinder three. One side of the pressing block is slidably connected to one side of the guide rail.

[0010] Preferably, the vibratory feeding assembly includes a vibratory feed pan, which is located behind the base plate. A shaped guide tube is provided on one side of the vibratory feed pan, and a guide platform is provided at one end of the shaped guide tube.

[0011] Preferably, the feeding assembly includes a clamping platform, which is disposed on one side of the base plate and in front of the guide platform, and a cylinder is disposed on one side of the clamping platform.

[0012] Preferably, the product placement part includes a cylinder four, which is disposed on the upper side of the base plate. A chain guide rail is disposed on the upper side of the base plate. A product placement seat is disposed on the shaft end of the cylinder four. One side of the product placement seat is slidably connected to one side of the chain guide rail. A cylinder five is disposed on the upper side of the base plate. A limit strip is disposed on the shaft end of the cylinder five. The limit strip is located above the product placement seat.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] Automated operation process: The entire device integrates multiple automated components, such as vibration feeding components, pushing components, and moving gripper components, which can automatically complete a series of processes such as feeding, gripping, transferring and assembling plastic-coated terminals without a lot of manual intervention. Compared with the traditional manual assembly method, it greatly improves the assembly speed and effectively shortens the production cycle. It is especially suitable for large-scale production scenarios and can significantly improve production efficiency.

[0015] Flexible gripper movement: The electric slide rail in the movable gripper assembly, along with the connector, cylinder one, and cylinder two, allows the grippers to move flexibly in multiple directions. The electric slide rail enables a wide range of horizontal position adjustments, while cylinder one and cylinder two control the precise changes in the grippers' vertical direction and opening / closing motion, respectively. This allows for the rapid and accurate transfer of plastic-coated terminals between different workstations, reducing the connection time between processes and further improving overall assembly efficiency.

[0016] Precise pressing positioning: The pressing component is driven by a three-cylinder press block, which slides along the guide rail, ensuring the linearity and stability of the pressing action. During the assembly of the plastic-coated terminals into the product, the pressing block can apply pressure precisely, accurately placing and fixing the terminals in the corresponding positions on the product. This effectively avoids assembly defects caused by pressing position deviations or uneven force, ensuring assembly accuracy and improving the product qualification rate.

[0017] Orderly material conveying and positioning: The vibratory feeding assembly utilizes a vibratory feeder, shaped guide tube, and guide platform to orderly convey the plastic-coated terminals according to a specific posture and sequence, providing excellent material preparation for subsequent gripping and assembly. The clamping platform and cylinder of the pushing assembly further position and push the material, ensuring accurate positioning of the terminals when entering the assembly stage. This works seamlessly with the grippers, guaranteeing precision throughout the entire assembly process from the source of material supply.

[0018] Positioning assurance of the product placement section: Cylinder four in the product placement section drives the product placement seat to move along the chain guide rail, which can accurately transport the product to be assembled to the assembly station. At the same time, cylinder five drives the limit bar to limit the upper part of the product placement seat, so that the product can maintain a stable position during the assembly process, prevent displacement, and further ensure that the plastic-coated terminals can be accurately assembled onto the product, thus improving the assembly quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] like Figures 1-4 As shown, an automatic assembly device for plastic-coated terminals vertically installs a support frame 2 at a predetermined position on the upper side of a base plate 1 and fixes it by tightening bolts to ensure the verticality and stability of the support frame, so that it can stably support the components to be installed later.

[0026] Install the electrical control box 3 on the right side of the support frame 2, using a suitable fixing method, such as bolt connection, to ensure that the electrical control box is installed firmly and that the connection lines with each electrical component are laid out reasonably for easy wiring and debugging. At the same time, pay attention to the protection of the electrical control box to avoid interference and damage from the external environment.

[0027] Install the electric slide rail 4 on one side of the support frame 2 and secure it firmly with bolts, ensuring that the levelness and straightness of the electric slide rail meet the requirements so that the gripper can move smoothly and accurately on it. Install the connector 5 on one side of the electric slide rail 4, ensuring that the connector is tightly connected to the slide rail and can slide smoothly. Next, install the cylinder 6 on one side of the connector 5 and secure it with bolts, ensuring that the axis of the cylinder 6 is aligned with the design direction without tilting or offset. Then connect the shaft end of the cylinder 6 to the mounting plate 7. The connection method can be a pin connection or a threaded connection, ensuring that the connection is firm and can rotate flexibly, so that the mounting plate 7 can move smoothly with the extension and retraction of the cylinder 6. Cylinder 2 8 is installed on one side of mounting plate 7, and a suitable fixing method is used to ensure that cylinder 2 is firmly connected to the mounting plate and its axis is perpendicular to the mounting plate. Finally, gripper 9 is installed on the shaft end of cylinder 2 8 to ensure that the gripper can open and close flexibly and that the gripping force meets the gripping requirements of plastic-coated terminals. Through the coordinated installation of various components, the gripper can move and operate precisely in three-dimensional space, providing a guarantee for the subsequent gripping and transfer of plastic-coated terminals.

[0028] Cylinder 3 10 is installed on the upper side of mounting plate 7 and secured firmly with bolts, ensuring its axis is perpendicular to the mounting plate to guarantee the accuracy of the pressing action. A guide rail 11 is installed on one side of mounting plate 7, ensuring it is securely fixed to the mounting plate and parallel to the required dimensions. One side of the pressing block 12 is then slidably connected to one side of the guide rail 11, ensuring smooth sliding on the guide rail. Simultaneously, the shaft end of cylinder 3 10 is connected to the pressing block 12, ensuring a secure connection. When the pressing assembly is in operation, cylinder 3 10 drives the pressing block 12 to move smoothly up and down along the guide rail 11, performing precise pressing operations on the plastic-coated terminals, ensuring accurate positioning and reliable connection during assembly.

[0029] The vibratory feeder 18 is placed at a predetermined position behind the base plate 1 and stabilized using shock-absorbing pads or other fixing devices to prevent excessive vibration from being transmitted to other components during operation. A shaped guide tube 19 is installed on one side of the vibratory feeder 18, ensuring a tight connection between the guide tube and the feeder's outlet without gaps or leakage, allowing the plastic-coated terminals to smoothly enter the guide tube from the vibratory feeder. One end of the guide tube 19 is connected to the guide platform 20, ensuring a secure and smooth connection, allowing the plastic-coated terminals to be arranged orderly on the guide platform 20, preparing for subsequent pushing and gripping operations. The installation of the vibratory feeding assembly enables automatic feeding and orderly arrangement of the plastic-coated terminals, improving assembly efficiency and automation.

[0030] The clamping platform 21 is installed on one side of the base plate 1 and in front of the guide platform 20. It is fixed with bolts to ensure that the clamping platform is firmly installed and accurately positioned, with an appropriate gap between it and the guide platform to facilitate the pushing of the plastic-coated terminals. A cylinder 6 22 is installed on one side of the clamping platform 21, ensuring that the axis of cylinder 5 is parallel to the clamping platform. The shaft end of cylinder 6 22 is connected to the pushing part of the clamping platform 21, ensuring a firm connection and flexible pushing capability. When the pushing assembly is working, cylinder 6 22 can accurately push the plastic-coated terminals on the guide platform 20 to the predetermined position for easy gripping by the grippers. In conjunction with the vibratory feeding assembly, automatic feeding and positioning of the plastic-coated terminals is achieved, improving the accuracy and efficiency of assembly.

[0031] Install cylinder 4 (13) on the upper side of base plate 1 and secure it firmly with bolts, ensuring its axis is aligned with the design direction. Then connect the shaft end of cylinder 4 (13) to product placement seat 15 using either a pin connection or a threaded connection, ensuring a secure connection and flexible rotation so that product placement seat 15 can move smoothly with the extension and retraction of cylinder 4. Install chain guide rail 14 on the upper side of base plate 1, ensuring it is securely fixed to the base plate and parallel to the required dimensions. Slidably connect one side of product placement seat 15 to one side of chain guide rail 14, ensuring smooth sliding of the product placement seat on the guide rail, achieving precise movement and positioning of the product placement seat. A cylinder 16 is installed on the upper side of the base plate 1. The shaft end of the cylinder 16 is connected to the limiting strip 17 to ensure a firm connection. When the product is placed on the product placement seat 15, the cylinder 16 can drive the limiting strip 17 to descend, thereby limiting and fixing the product and preventing it from shifting during assembly. This ensures that the plastic-coated terminal can be accurately assembled onto the product. By installing the product placement part, the stable placement and precise positioning of the product to be assembled are achieved, thereby improving assembly quality and efficiency.

[0032] In this embodiment, the device is prepared as follows: The automatic assembly device for plastic-coated terminals is placed on a stable, clean, and dry workbench, ensuring that the four support feet of the base plate 1 are in good contact with the workbench surface and that the entire device is stable without any shaking. The connection points of each component are checked to confirm that the support frame 2 is firmly installed on the base plate 1 and that the connection lines between the electrical control box 3 and each electrical component are correctly connected without any damage, short circuits, or other problems.

[0033] Material preparation: Select a batch of standard plastic-coated terminals with uniform specifications, such as the pin length of the terminal being [specific length value], the diameter of the plastic encapsulation part being [specific diameter value], and the material being [specific material]. At the same time, prepare matching products to be assembled, and ensure that the terminal mounting hole dimensions on the products meet the design requirements to ensure that the two can be matched for assembly operations.

[0034] Parameter settings: Through the operation interface of the electrical control box 3, the moving speed and stroke range of the electric slide rail 4, the extension and retraction stroke, action sequence and action time interval of each cylinder (cylinder 1 6, cylinder 2 8, cylinder 3 10, cylinder 4 13, cylinder 5 16, cylinder 6 22) are set according to the specifications of the plastic-coated terminals and products, so that the components of the device can work together in accordance with the preset process.

[0035] Start-up of equipment and feeding of materials

[0036] Connect the power supply to the device and start the electrical control box 3 to power on the entire device and put it into the working preparation state. The vibrating material tray 18 starts to work. By adjusting its vibration frequency and amplitude, the plastic-coated terminals placed in the vibrating material tray are transported in an orderly manner along the irregular guide tube 19 to the guide table 20 under the action of vibration. Finally, they are neatly arranged on the guide table 20, waiting for the next pushing operation.

[0037] Material pushing and clamping operations

[0038] Once the plastic-coated terminals on the guide table 20 are ready, cylinder six 22 is activated, its piston rod extends, and pushes the pushing component on the clamping table 21, pushing the plastic-coated terminal at the foremost position to the predetermined gripping position. At the same time, the movable gripper assembly begins to move, the electric slide rail 4 drives the connecting piece 5 to move above the gripping position, then the piston rod of cylinder one 6 extends, driving the mounting plate 7 to descend to the appropriate height. Then, cylinder two 8 drives the gripper 9 to close, accurately gripping the plastic-coated terminal and completing the gripping action.

[0039] Terminal transfer and product positioning

[0040] After the gripper 9 picks up the plastic-coated terminal, the piston rod of cylinder 6 retracts, causing the mounting plate 7 to rise. The electric slide rail 4 then restarts, moving the connector 5 and the gripper 9 holding the plastic-coated terminal to the corresponding assembly position above the product placement seat 15. During this period, cylinder 13 extends its piston rod according to a preset stroke, pushing the product placement seat 15 along the chain guide rail 14 to the assembly station. Subsequently, cylinder 16 drives the limit bar 17 to descend, limiting and fixing the product to be assembled on the product placement seat 15 to ensure accurate product positioning and prevent displacement.

[0041] Press-down assembly operation

[0042] Once the gripper 9 moves the plastic-coated terminal to the precise assembly position on the product, the cylinder 3 10 on the upper side of the mounting plate 7 is activated, its piston rod extends, and pushes the lower pressure block 12 to slide smoothly down the guide rail 11, precisely pressing the plastic-coated terminal held by the gripper 9 into the corresponding mounting hole of the product. After reaching the preset assembly depth and pressure requirements, the piston rod of the cylinder 3 10 retracts, driving the lower pressure block 12 back to the initial position, and at the same time, the gripper 9 is released, completing the assembly process of one plastic-coated terminal on the product.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
