Description

Technical Field

[0001] This utility model relates to the field of flexible connector processing technology, and more specifically, to a hot melt shrink sleeve flipping heating fixture. Background Technology

[0002] Flexible connectors are special pipe fittings primarily used to connect powder processing equipment and pipelines to compensate for displacement and stress caused by equipment or pipeline vibration, and also for conveying powder. They are made of bare copper wire or tin-plated copper braided wire, manufactured using a cold-pressing method, and feature high conductivity, high current carrying capacity, and low resistance. Flexible connectors are widely used in metallurgy (e.g., electrolytic aluminum, electrolytic zinc, electrolytic copper), chemicals (e.g., electroplating), power substations (e.g., power plants, power stations), and electrical equipment (e.g., transformers, distribution cabinets) to compensate for displacement and stress caused by equipment or pipeline vibration, ensuring stable equipment operation. A heat-shrink sleeve is required on the surface of the flexible connector; this sleeve provides corrosion protection. The heat-shrink sleeve is shrunk onto the flexible connector by heating and tooling.

[0003] Some existing hot melt shrink sleeve processing fixtures lack a flipping function, which may lead to uneven heating of certain parts of the shrink sleeve and reduce its adhesion effect. Therefore, we propose a hot melt shrink sleeve flipping heating fixture. Utility Model Content

[0004] To solve the above problems, this utility model provides a hot melt shrink sleeve flipping and heating fixture, which adopts the following technical solution:

[0005] A hot melt shrink sleeve flipping and heating fixture includes a base, with columns at each of the four corners of the base's bottom end, a support frame at the top of the base, a support assembly at the top of the base, a first robotic arm and a second robotic arm symmetrically distributed on the inner wall of the top of the support frame, and electric grippers at the ends of the first and second robotic arms. Two symmetrically distributed grooves are formed at the top of the base, and screws are rotatably mounted in the two grooves. Support blocks are fitted onto the side walls of the two screws. First reduction motors are provided on both sides of the base, and the output shafts of the two first reduction motors are fixedly connected to the opposite ends of the screws on the same side. A clamping assembly is provided between the two support blocks. Two symmetrically distributed support plates are fixedly mounted at the top of the base, and a heating assembly is provided between the two support plates.

[0006] By adopting the above technical solution, when the equipment is in use, the first robotic arm drives the electric gripper on the same side to clamp the flexible connector with a shrink sleeve. The first robotic arm moves the flexible connector above the support assembly, which supports the flexible connector and adjusts its height for easier clamping. The flexible connector is then lifted between the heating components by the support assembly. Subsequently, the first geared motor drives the screw on the same side to rotate, which in turn drives the support block on the same side to slide within the groove on the same side. The two support blocks drive the clamping assembly to rotate, thus clamping and fixing the flexible connector. The clamping assembly also drives the flexible connector to rotate, ensuring uniform heating and improving product processing quality. After the flexible connector is processed, the second robotic arm drives the electric gripper on the same side to remove the product from the equipment, thus unloading the material. The cooperation between the first and second robotic arms allows for simultaneous loading and unloading, improving the equipment's processing efficiency.

[0007] Furthermore, the support assembly includes a placement plate above the base, a mounting frame at the bottom of the base, a second cylinder inside the mounting frame, the piston shaft of the second cylinder slidingly passing through the base, and the piston shaft of the second cylinder being fixedly connected to the bottom end of the placement plate.

[0008] By adopting the above technical solution, the first robotic arm clamps the flexible connector and moves it above the placement plate. The placement plate can support the flexible connector, and the second cylinder can drive the placement plate and the flexible connector to rise and fall, thereby adjusting the height of the flexible connector and facilitating subsequent clamping.

[0009] Furthermore, the clamping assembly includes a mounting plate disposed on the top of the support block. Each of the two mounting plates has a mounting box on its opposite side. Each of the two mounting boxes contains a second reduction motor. A rotating rod is rotatably mounted on each of the two mounting plates on its opposite side. The opposite ends of the two rotating rods extend through the mounting box on the same side. The opposite ends of the two rotating rods are fixedly connected to the output shaft of the second reduction motor on the same side. A clamping plate is disposed on each of the opposite ends of the two rotating rods. A rubber plate is fixedly mounted on each of the opposite sides of the two clamping plates. A pressure sensor is disposed between the clamping plate and the rotating rod on the same side.

[0010] By adopting the above technical solution, the first geared motor drives the screw on the same side to rotate, and the screw drives the support block on the same side to slide in the groove on the same side. The two support blocks, along with the mounting plate, mounting box, rotating rod and clamping plate on the same side, move synchronously towards the flexible connector, so that the two clamping plates and the opposite side of the flexible connector come into contact, which can play the role of clamping and fixing the flexible connector. Furthermore, the second geared motor can drive the rotating rod to rotate synchronously with the clamping plate, which can play the role of driving the flexible connector to rotate, which facilitates uniform heating of the shrink sleeve and helps to maintain the processing quality of the product.

[0011] Furthermore, each of the two rotating rods has a mounting plate fitted on its sidewall, and each of the two mounting plates has an annular groove on its opposite side. Multiple stabilizing plates arranged in a circular array are slidably installed in each of the two annular grooves, and the stabilizing plates are fixedly connected to the mounting plates on the same side.

[0012] By adopting the above technical solution, when the rotating rod rotates, the rotating rod drives the mounting plate to rotate synchronously, and the mounting plate drives the stabilizing plate to slide in the annular groove on the same side. The cooperation of the mounting plate, the stabilizing plate and the annular groove helps to maintain the stability of the rotating rod and the clamping plate rotating.

[0013] Furthermore, stabilizing rods are fixedly installed on both sides of the two mounting plates, and a sliding groove matching the stabilizing rod on the same side is provided at the top of the base.

[0014] By adopting the above technical solution, when the mounting plate moves, the mounting plate, along with the stabilizing rod, slides within the groove on the same side. The cooperation between the stabilizing rod and the groove helps to maintain the stability of the mounting plate's movement.

[0015] Furthermore, positioning blocks are fixedly installed at the bottom of both mounting plates, and positioning grooves matching the positioning blocks on the same side are opened at the top of the two support blocks.

[0016] By adopting the above technical solution, when installing the mounting plate, the worker places the mounting plate on top of the support block, so that the positioning block at the bottom of the mounting plate engages with the positioning groove at the top of the support block. Through the cooperation of the positioning block and the positioning groove, the mounting plate is positioned, which facilitates subsequent fixing with fasteners of existing technology.

[0017] Furthermore, the heating assembly includes two arc-shaped plates disposed above the base. Each of the two arc-shaped plates has a plurality of heating tubes arranged in a ring array on its inner side. Each of the two support plates has a first cylinder on its opposite side. The piston shafts of the two first cylinders slide through the support plates on the same side, and the ends of the piston shafts of the two first cylinders are fixedly connected to the opposite side of the arc-shaped plates on the same side.

[0018] By adopting the above technical solution, after the flexible connector is clamped, the heating tube generates heat to bake the shrink sleeve, which facilitates subsequent shrinkage. Furthermore, the first cylinder can drive the arc plate on the same side and the heating tube to move synchronously towards the flexible connector, thereby adjusting the distance between the heating tube and the flexible connector and increasing the processing efficiency of the product.

[0019] In summary, this utility model has the following beneficial technical effects:

[0020] (1) In this utility model, the clamping component is set to clamp and fix the soft connector. The second reduction motor can drive the rotating rod to rotate the clamping plate synchronously, thereby driving the soft connector to rotate. This facilitates the uniform heating and shrinking of the shrink sleeve and helps maintain the processing quality of the flattening.

[0021] (2) In this utility model, a pressure sensor is provided between the clamping plate and the rotating rod to detect the clamping degree of the flexible connector. By the clamping force fixed by the equipment, the screw is driven to rotate by the first reduction motor, thereby causing the support block to move with the clamping plate to contact the opposite side of the flexible connector. When the clamping force reaches the predetermined value, the movement of the clamping plate can be stopped, which helps to avoid damage to the flexible connector due to excessive clamping.

[0037] When the device is in use, the first robotic arm 9 drives the electric gripper on the same side to clamp the flexible connector with the shrink sleeve. The first robotic arm 9 clamps the flexible connector and moves it above the placement plate 24. The placement plate 24 can support the flexible connector, and the second cylinder 23 can drive the placement plate 24 and the flexible connector to rise and fall, thereby adjusting the height of the flexible connector and facilitating subsequent clamping.

[0038] The base 1 has two symmetrically distributed grooves 16 at its top. Screws 17 are rotatably installed in the two grooves 16. Support blocks 20 are fitted on the side walls of the two screws 17. First reduction motors 4 are provided on both sides of the base 1.

[0039] The first geared motor 4 drives the screw 17 on the same side to rotate, and the screw 17 drives the support block 20 on the same side to slide in the groove 16 on the same side. The two support blocks 20, along with the mounting plate 11, mounting box 3, rotating rod 12 and clamping plate 15 on the same side, move synchronously towards the flexible connector, so that the two clamping plates 15 and the opposite side of the flexible connector come into contact, which can play the role of clamping and fixing the flexible connector. The second geared motor 25 can drive the rotating rod 12 to rotate synchronously with the clamping plate 15, which can play the role of driving the flexible connector to rotate, which is conducive to the uniform heating of the shrink sleeve and helps to maintain the processing quality of the product.
