[0031] 5x speed chain body. Implementation

[0032] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of the invention.

[0033] Specific Implementation Example 1: Please refer to Figure 1-7 An external attachment device for buoy assembly is provided. This external attachment device needs to be combined with a high-speed chain conveyor 5 and a PLC or host computer control program to realize clamping and arbitrary posture external attachment assembly during the assembly process of a buoy, including:

[0034] Lifting and rotating mechanism 1, please refer to Figure 2 The lifting and rotating mechanism 1 includes a lifting cylinder 11, a top plate 12, a support base 13, a rotating cylinder 14, and a turntable 15 arranged sequentially from bottom to top. Specifically, the lifting cylinder 11 and the top plate 12 are both fixedly mounted on the double-speed chain. The output shaft of the lifting cylinder 11 passes through the top plate 12 and is fixedly connected to the lower end of the support base 13. The rotating cylinder 14 is fixedly located at the upper end of the support base 13, and the output shaft of the rotating cylinder 14 is fixedly connected to the axis of the turntable 15. The lifting and rotating mechanism 1 also includes a stop block 16, a positioning pin 17, a damping buffer 18, and a proximity switch (not shown in the figure). Four stop blocks 16 and four positioning pins 17 are provided. The stop blocks 16 are arranged around the axis of the turntable 15. The positioning pins 17 are evenly distributed around the axis of the turntable 15 at the upper end of the turntable 15, located at the lower end of the turntable 15. The damping buffer 18 and the proximity switch are both fixed on the speed-doubling chain, and the position of the damping buffer 18 is selectively corresponding to the position of the stop block 16. When the rotary cylinder 14 drives the turntable 15 to rotate, the damping buffer 18 can avoid the rigid impact after the turntable 15 rotates to the position, ensuring the relative stability of the bearing mechanism and the position of the items in the mechanism on the turntable 15. The position of the proximity switch corresponds to the position of the turntable 15. In this embodiment, for ease of control, the lifting cylinder 11, the rotary cylinder 14 and the proximity switch are all connected to the external PLC or host computer control program circuit.

[0035] Power-on mechanism 2, please refer to Figure 3The power supply mechanism 2 includes a double-guide rod cylinder 21, a mounting plate 22, an insulating electrode holder 23, an electrode 24, and a fixing plate 25. The double-guide rod cylinder 21 is mounted on the speed-multiplying chain via the fixing plate 25. The guide rods of the double-guide rod cylinder 21 are fixedly connected to the lower end of the mounting plate 22. The insulating electrode holder 23 is located on the mounting plate 22. The electrode 24 is located on the insulating electrode holder 23. The electrode 24 is made of wear-resistant conductive material and can be connected to the neutral, live, ground, and signal wires. The bottom of the electrode 24 has a metal spring. To ensure conductivity while reducing wear on the contact surface; in this embodiment, five insulating electrode seats 23 and five electrodes 24 are provided, and the insulating electrode seats 23 and electrodes 24 are arranged in a one-to-one correspondence; it should also be noted that the double guide rod cylinder 21 has double guide rods inside, which provides better support and stability than the traditional single rod cylinder, and is conducive to the lifting and lowering of the electrodes 24; similarly, for convenient control, the double guide rod cylinder 21 is connected to an external PLC or host computer control program circuit.

[0036] For power mechanism 3, please refer to [link / reference]. Figure 4 The power mechanism 3 includes a carrier plate 31, a reduction motor 32, a coupling 33, an output shaft 34, a bearing seat 35, and two electrode plates (not shown in the figure). The carrier plate 31 is placed in the guide grooves of two double-speed chain bodies 5. A through groove 311 and pin holes 312 are longitudinally formed on the carrier plate 31. There are two through grooves 311, both located at the front of the carrier plate 31 body, and the two electrode plates are correspondingly located within the through grooves 311. There are four pin holes 312, evenly distributed in the middle of the carrier plate 31 body. The reduction motor 32 is located in the middle of the upper end of the carrier plate 31, and is connected to the two electrode plates via wires. The shaft of the reduction motor 32 is connected to the beginning of the output shaft 34 via a coupling 33. The bearing seat 35 is located on the right side of the upper end of the carrier plate 31, and the beginning of the output shaft 34 passes through the bearing seat 35. The main purpose of the seat 35 is to provide support for the output shaft 34, so as to ensure that the output shaft 34 can rotate synchronously with the shaft of the geared motor 32 when the geared motor 32 is working. Furthermore, the geared motor 32 is a planetary reducer, which has the advantages of compact structure, small backlash and high precision compared with worm gear reducers and gear reducers. The geared motor 32 is powered by 24V, which is safe and reliable. At the same time, the brake is in the energized and released state, which is conducive to the operation of the power mechanism. In addition, the power mechanism 3 also includes a counterweight and a protective cover (not shown in the figure). The counterweight is fixed on the left side of the upper end of the carrier plate 31. The counterweight is used to balance the product and the power mechanism and maintain the stability of the product during operation. The protective cover is set on the outer periphery of the geared motor 32 to prevent dust. The size of the positioning pin 17 is adapted to the pin hole 312, and during assembly, the positioning pin 17 and the pin hole 312 are set one-to-one.

[0037] Buoy vehicle 4, please refer to Figure 5 The buoy carrier 4 includes a main clamping part, a secondary clamping part, and several spring buckles 44;

[0038] The main clamping part includes a tapered base 41, a cover plate 42, a U-shaped plate 43, and a baffle frame 45. The tapered base 41 is an arc-shaped plate structure with a semi-circular cross-section. A protruding connecting seat 411 is provided on the outer arc side of the tapered base 41. The connecting seat 411 is detachably connected to the tail end of the output shaft 34. When the reduction motor 32 is working, the reduction motor 32 can drive the tapered base 41 to rotate. The cover plate 42 is an arc-shaped plate structure. The cover plate 42 covers the tapered base 41, and the inner arc side of the cover plate 42 is aligned with the inner arc side of the tapered base 41. The cover plate 42 is rotatably connected to the rear end of the tapered base 41, and the other end of the cover plate 42 is detachably connected to the front end of the tapered base 41 via a spring buckle 44. In this embodiment, three cover plates 42 are provided, and the three cover plates 42 are arranged along the axis of the tapered base 41 at the left, middle, and right parts of the tapered base 41. The U-shaped plate 43 is located on the right side of the tapered base 41 and inside the cover plate 42, and is used to partially block the right port of the tapered base 41. The baffle bracket 45 is located on the left side of the outer arc side of the tapered base 41.

[0039] The secondary clamping part consists of two sets of clamping components; please refer to Figure 7 The clamping assembly includes a plastic ring baffle 46, a parachute mounting clip 47, a gear 48, and a fixed shaft 49. The tail end of the plastic ring baffle 46 and the gear 48 are both sleeved on the fixed shaft 49. The parachute mounting clip 47 is located at the head end of the plastic ring baffle 46. The clamping assembly is rotatably connected to the baffle frame 45 via the fixed shaft 49. In addition, the axis of the fixed shaft 49 is parallel to the axis of the tapered base 41. The two sets of clamping assemblies are positioned correspondingly and are linked by the meshing of the gear 48. When the two sets of clamping assemblies are combined, they are fixed in position by the spring buckle 44 to achieve the purpose of clamping. Furthermore, the length direction of the plastic ring baffle 46 is perpendicular to the axis of the tapered base 41, and when the two sets of clamping assemblies are combined, the plastic ring baffle 46 at least partially covers the left side of the tapered base 41 to block the left port of the tapered base 41.

[0040] The parachute mounting clip 47 has an open box-like structure. The parachute mounting clip 47 and the baffle frame 45 are respectively placed on both sides of the axis of the tapered base 41. In this embodiment, the parachute mounting clip 47 is used to roll up and place flexible parts that are not conducive to circulation. At the same time, when the two parachute mounting clips 47 are combined, they can achieve clamping perpendicular to the axis of the tapered base 41. When the buoy carrier 4 clamps a sonar buoy, the main clamping part and the auxiliary clamping part can clamp the sonar buoy in different directions in space, which can solve the problem of difficult clamping during the buoy assembly process. In another embodiment, the shape of the external carrier and the clamping direction of the main clamping part and the auxiliary clamping part can be designed according to the product shape, process requirements and the working mode of existing equipment.

[0041] The working process of this external vehicle device is as follows:

[0042] Prepare spare parts and auxiliary materials, and load them into the buoy carrier;

[0043] After the sensor detects that the carrier plate in the power mechanism is in place, the lifting cylinder in the lifting and rotating mechanism lifts the turntable, so that the positioning pin aligns with the pin hole on the carrier plate.

[0044] After the lifting is completed, the energizing mechanism receives a signal, the double-guide rod cylinder works, and drives the electrode to contact the electrode plate, thus energizing the power mechanism;

[0045] After receiving a signal, the geared motor in the power mechanism rotates in the specified direction and angle according to the instruction, and drives the buoy carrier to rotate to the specified posture through the coupling and output shaft, and the power supply mechanism is de-energized.

[0046] Complete the assembly process or complete the predetermined task using unmanned equipment;

[0047] The operator inputs the release command, the lifting cylinder is de-pressurized, the power mechanism descends to the double-speed chain of the double-speed chain line, and the line's stop mechanism releases the line.

[0048] It should be noted that in actual production, since the assembly equipment used with the double-speed chain loop is located at different positions on the loop, such as inside or outside, a workstation needs to be reserved on the loop to change the position of the buoy carrier. At this reserved workstation, the power mechanism will adjust the external carrier to a horizontal position (i.e., the axis of the tapered base is parallel to the double-speed chain body). Then, the rotary cylinder in the lifting and rotating mechanism will work to rotate the power mechanism and the buoy carrier horizontally by 180° to perform a mirror transformation. This allows the buoy carrier to change positions on both sides of the double-speed chain body, facilitating the assembly of the products carried inside the buoy carrier.

[0049] This technical solution solves the problems of clamping difficulties, low assembly efficiency, inapplicability to existing on-site equipment, and high labor intensity in the assembly process of a certain buoy. In actual production, it can realize full clamping and arbitrary posture external assembly in the assembly process of a certain buoy, improve assembly efficiency, reduce labor intensity, and improve quality consistency.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
