Description

Technical Field

[0001] The present invention relates to the technical field of high - voltage switchgear cabinets, and particularly to an automatic assembly device for wire assemblies of high - voltage switchgear cabinets. Background Art

[0002] For some standardized high - voltage switchgear cabinets, wires are pre - assembled according to fixed circuit configurations and connection methods. For such high - voltage switchgear cabinets, the wire assembly steps can be completed on the factory production line; however, for some high - voltage switchgear cabinets with specific requirements, due to unique circuit designs, wire assembly may not be able to be pre - completed in the factory. For example, in the switchgear cabinets of some industrial automation production lines, their circuits need to closely cooperate with specific production equipment and technological processes, and wire assembly needs to be carried out on - site according to the actual situation.

[0003] When assembling wires for a high - voltage switchgear cabinet, the pre - processed wires need to be connected to the terminal blocks of electrical components. During assembly, the operator needs to hold the wire with one hand to ensure that the conductor of the wire is fully inserted into the bottom of the terminal (if a copper nose is installed at the end of the wire, the copper nose should be aligned with the terminal block), and at the same time, insert a screw into the terminal block with the other hand. Then, free one hand to hold a screwdriver (or an electric screwdriver) to tighten the screw. In this process, since the screw cannot be limited, the screw is prone to being twisted. Once the screw is twisted, it will not only damage the threads of the screw and the connecting parts, but also may lead to an insecure connection and require reinstallation;

[0004] In addition, since there are many wires to be assembled in the high - voltage switchgear cabinet, and the installation positions of the terminal blocks and wire noses are relatively narrow, and the screw mounting holes of the terminal blocks of different electrical components have different structures, some are countersunk holes and some are blind holes. According to the traditional installation method, installing copper noses, placing screws, and tightening screws one by one will be very time - consuming and mentally exhausting. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems raised in the background art, and to propose an automatic assembly device for wire assemblies of high - voltage switchgear cabinets.

[0006] To achieve the above - mentioned purpose, the present invention adopts the following technical solutions:

[0007] An automatic assembly device for wire assemblies of high - voltage switchgear cabinets, comprising: a housing, an adjusting mechanism, an electric screwdriver, and a wiring mechanism. The electric screwdriver is fixedly installed on the adjusting mechanism, the adjusting mechanism is installed on the housing, a handle is fixedly installed below the housing, a slide rail is fixedly installed in front of the housing, and a plurality of wiring mechanisms are slidably installed in the slide rail;

[0008] The wiring mechanism includes a sliding plate, a screw limiting component, and a wire limiting clip. The bottom of the sliding plate is slidably installed in the slide rail. The wire limiting clip is fixed to the sliding plate through a universal rod. The screw limiting component includes a switching plate, a first screw jaw, and a second screw jaw. The switching plate is rotatably installed on the sliding plate and is used to switch the positions of the first screw jaw and the second screw jaw.

[0009] As a further aspect of the present invention: The adjusting mechanism includes a feeding component, a fine-tuning component, and a mounting component;

[0010] The feeding component includes a front fixing plate, a rear fixing plate, a threaded rod, and a sleeve. The front fixing plate and the rear fixing plate are fixedly installed in the housing. The front and rear ends of the threaded rod are respectively rotatably connected to the front fixing plate and the rear fixing plate, and the threaded rod is driven to rotate by a motor. The sleeve is sleeved on the threaded rod and is threadedly connected to the threaded rod. At the same time, the bottom of the sleeve is slidably connected to the bottom surface of the housing;

[0011] A connecting block is fixedly installed at the top of the sleeve. A sliding groove for the connecting block to move is provided at the top of the housing. The connecting block passes through the sliding groove and is connected to the fine-tuning component.

[0012] As a further aspect of the present invention: The fine-tuning component includes a fine-tuning base, a fine-tuning block, and a fine-tuning knob. The bottom of the fine-tuning base is fixed to the connecting block. The fine-tuning base is in a long strip shape. The direction of the fine-tuning base is perpendicular to the direction of the threaded rod in the horizontal plane. A rack is fixedly installed on the upper surface of the fine-tuning base. The fine-tuning block is slidably installed with the rack. At the same time, a gear meshing with the rack is installed in the fine-tuning block. At the same time, a fine-tuning knob for controlling the rotation of the gear is installed on the fine-tuning block.

[0013] As a further aspect of the present invention: The mounting component includes a mounting base and a mounting cover. The mounting base and the mounting cover are fixed by screws to clamp the electric screwdriver. The bottom of the mounting base is fixedly connected to the fine-tuning block.

[0014] As a further aspect of the present invention: The first screw jaw is composed of two first jaws. One end of the first jaw is set in a pointed shape, and the other end is rotatably connected to the switching plate. The two first jaws are symmetrically arranged one above the other. At the same time, first springs are fixedly installed on the outer sides of the two first jaws. A stop block is fixedly installed on the switching plate at the corresponding position of the first spring. The first spring is fixedly connected to the stop block. The pointed ends of the two first jaws are joined together, and a first limiting hole for installing a screw is provided at the joined pointed end. The inner diameter of the first limiting hole gradually decreases towards the pointed end direction.

[0015] As a further solution of the present invention: The second screw clamping jaw is composed of a limiting cylinder and two second clamping jaws. The limiting cylinder is a conical cylinder, and the limiting cylinder is fixed to the switching plate through a connecting rod. Two second clamping jaws are fixedly connected inside the limiting cylinder through a second spring. The two second clamping jaws are symmetrically distributed and are assembled into a funnel shape. The inner diameters of the two second clamping jaws form a second limiting hole for installing screws. One inner wall of the second limiting hole is a conical surface, and the other end is a cylindrical surface.

[0016] As a further solution of the present invention: The switching plate is provided with a first guiding groove and a second guiding groove at positions corresponding to the first limiting hole and the second limiting hole.

[0017] As a further solution of the present invention: The wire limiting clip is composed of a left clamping block and a right clamping block. The left clamping block and the right clamping block are rotatably connected through a rotating shaft, and a cushion block is installed inside the left clamping block and the right clamping block through a buffer spring.

[0018] Compared with the existing technology, the advantages of the present invention are as follows:

[0019] 1. The copper nose, screw, and electric screwdriver at the end of the wire are simultaneously limited and fixed to form an operating whole. The user only needs to operate with one hand to accurately connect and fix the wire to the wiring terminal in the high-voltage power distribution cabinet, ensuring a firm and stable connection between the copper nose, screw, and wiring terminal, effectively avoiding problems such as loosening, poor contact, and rework caused by uncoordinated two-handed operations resulting in the screw being screwed crooked.

[0020] 2. It supports pre-installing a row of wires and screws at one time and then performing continuous installation, enabling the entire installation process to be efficiently and continuously advanced, improving the overall installation efficiency and simplifying the installation operation process.

[0021] 3. For different types of electrical components, switchable first screw clamping jaws and second screw clamping jaws are designed, which are suitable for different wiring terminal installation holes, ensuring a tight and reliable connection in different application scenarios and reducing the installation difficulty caused by differences in electrical components.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Refer to Figure 1 - Figure 12 , an automatic assembly device for high-voltage switch cabinet wire assemblies, comprising a housing 1, an adjustment mechanism 2, an electric screwdriver 3, and a wiring mechanism 4. The adjustment mechanism 2 includes a feeding assembly 21, a fine-tuning assembly 22, and a mounting assembly 23. The housing 1 is a rectangular parallelepiped housing. The feeding assembly 21 of the adjustment mechanism 2 is installed inside the housing 1, and the fine-tuning assembly 22 and the mounting assembly 23 are installed outside the housing 1. A handle 11 is fixedly installed below the housing 1 to facilitate the operator to hold it with one hand.

[0037] The electric screwdriver 3 is fixedly installed on the mounting assembly 23. The mounting assembly 23 is composed of a mounting base 231 and a mounting cover 232. The mounting base 231 and the mounting cover 232 are fixed by screws to clamp the electric screwdriver 3. By loosening the screws on the mounting cover 232, the electric screwdriver 3 can be removed. The bottom of the mounting base 231 is fixedly connected to the fine-tuning assembly 22. Therefore, the left and right positions of the electric screwdriver 3 can be adjusted through the fine-tuning assembly 22.

[0038] As Figure 1 - Figure 4 shown, the fine-tuning assembly 22 includes a fine-tuning base 221, a fine-tuning block 222, and a fine-tuning knob 223. A rack 224 is fixedly installed on the upper surface of the fine-tuning base 221. The fine-tuning block 222 is slidably installed with the rack 224. A gear 225 meshing with the rack 224 is installed inside the fine-tuning block 222, and a fine-tuning knob 223 for controlling the rotation of the gear 225 is installed on the fine-tuning block 222.

[0039] The operator can turn the fine-tuning knob 223 to control the gear 225 to rotate left or right. Since the gear 225 meshes with the rack 224, when the fine-tuning knob 223 is turned, the gear 225 will roll meshingly on the rack 224, that is, the fine-tuning block 222 can move left and right on the rack 224. Since the mounting assembly 23 is fixed on the fine-tuning block 222, turning the fine-tuning knob 223 can adjust the left and right positions of the electric screwdriver 3.

[0040] The feeding assembly 21 includes a front fixing plate 211, a rear fixing plate 212, a threaded rod 213 and a sleeve 214. The front fixing plate 211 and the rear fixing plate 212 are fixedly installed on the bottom plate of the housing 1. The front and rear ends of the threaded rod 213 are respectively rotatably connected to the front fixing plate 211 and the rear fixing plate 212, and the threaded rod 213 is driven to rotate by a motor. The sleeve 214 is sleeved on the threaded rod 213 and is threadedly connected to the threaded rod 213. At the same time, the bottom of the sleeve 214 is slidably connected to the bottom surface of the housing 1; a connecting block 215 is fixedly installed at the top of the sleeve 214, and a sliding groove 12 for the connecting block 215 to move is provided at the top of the housing 1. The connecting block 215 passes through the sliding groove 12 and is connected to the fine-tuning base 221; the fine-tuning base 221 is in a long strip shape, and the direction of the fine-tuning base 221 is perpendicular to the direction of the threaded rod 213 in the horizontal plane;

[0041] When the motor drives the threaded rod 213 to rotate (a switch button for controlling the forward and reverse rotation of the threaded rod 213 can be set on the handle 11), the sleeve 214 will move forward or backward along the threaded rod 213. Since the fine-tuning base 221 is fixed on the sleeve 214, when the sleeve 214 moves forward and backward, it will drive the electric screwdriver 3 to move forward or backward.

[0042] As Figure 5 - Figure 10 As shown in the figure, a slide rail 13 is fixedly installed in front of the housing 1, and a plurality of wiring mechanisms 4 are slidably installed in the slide rail 13. The number of wiring mechanisms 4 can be increased or decreased according to the use requirements; the wiring mechanism 4 includes a slide plate 41, a screw limiting component 42 and a wire limiting clip 43. The bottom of the slide plate 41 is slidably installed in the slide rail 13. Sliding the slide plate 41 along the slide rail 13 can adjust the position of the wiring mechanism 4, or the wiring mechanism 4 can be directly removed.

[0043] The wire limiting clip 43 is fixed on the slide plate 41 through a universal rod 44 (the universal rod 44 is a universal flexible rod that can be bent and shaped arbitrarily). The wire limiting clip 43 is composed of a left clip block 431 and a right clip block 432. The left clip block 431 and the right clip block 432 are rotatably connected through a rotating shaft. The outer sides of the left clip block 431 and the right clip block 432 are provided with clip handles for easy pinching. When in use, fingers pinch the clip handles, open the left clip block 431 and the right clip block 432, put in the wire, and then release the clip handles. The left clip block 431 and the right clip block 432 will automatically clamp the wire.

[0044] The inner sides of the left clip block 431 and the right clip block 432 are provided with a cushion block 434 through a buffer spring 433. The cushion block 434 is made of an elastic material, and clamping it on the surface of the wire can avoid damaging the wire. After clamping the wire, by adjusting the universal rod 44, the copper nose at the end of the wire is aligned with the screw installed in the screw limiting component 42.

[0045] As Figure 7 - Figure 8As shown in the figure, the screw limiting component 42 includes a switching plate 421, a first screw jaw 422 and a second screw jaw 423. The switching plate 421 is rotatably mounted on the sliding plate 41, and rotating the switching plate 421 can switch the positions of the first screw jaw 422 and the second screw jaw 423.

[0046] The first screw jaw 422 is composed of two first jaws 4221. One end of the first jaw 4221 is set in a pointed shape, and the other end is rotatably connected to the switching plate 421. The two first jaws 4221 are symmetrically arranged one above the other, and springs 4222 are fixedly mounted on the outer sides of the two first jaws 4221. A stop block 4223 is fixedly mounted on the switching plate 421 at the corresponding position of the spring 4222. The spring 4222 is fixedly connected to the stop block 4223. The pointed ends of the two first jaws 4221 are joined together, and a first limiting hole 4224 for installing a screw is provided at the joined pointed end. The inner diameter of the first limiting hole 4224 gradually decreases towards the pointed end.

[0047] The first screw jaw 4221 is applicable to a terminal block with a common blind hole type screw mounting hole (as Figure 11 shown). The screw is installed into the first limiting hole 4224, and the first jaw 4221 clamps the screw. The screw is limited and fixed in the first limiting hole 4224. The electric screwdriver 3 is aligned with the screw for tightening. During the tightening process, the screw moves forward along the first limiting hole 4224. Since the inner diameter of the first limiting hole 4224 is a reduced diameter structure, the first jaw 4221 will gradually open during the forward tightening process of the screw. During the entire tightening process, the first limiting hole 4224 guides the screw and prevents the screw from being twisted.

[0048] Since the pointed part of the first screw jaw is relatively large and cannot penetrate into the counterbore, it is suitable for installing screws in ordinary blind holes, while the second screw jaw 423 is applicable to counterbores.

[0049] The second screw jaw 423 is composed of a limiting cylinder 4231 and two second jaws 4232. The limiting cylinder 4231 is a conical cylinder. The limiting cylinder 4231 is fixed to the switching plate 421 through a connecting rod 4233. Two second jaws 4232 are fixedly connected inside the limiting cylinder 4231 through a spring 4234. The two second jaws 4232 are symmetrically distributed and joined together to form a funnel shape. The inner diameters of the two second jaws 4232 form a second limiting hole 4235 for installing a screw. One inner wall end of the second limiting hole 4235 is a conical surface, and the other end is a cylindrical surface.

[0050] It should be noted here that since the diameter of the mounting counterbore for the terminal is larger than the diameter of the screw nut, as long as the outer diameter of the second jaw 4232 is smaller than the diameter of the terminal counterbore, it can penetrate into the terminal counterbore. When in use, place the screw into the second limiting hole 4235, the second jaw 4232 will clamp the outer edge of the screw, and then the electric screwdriver 3 is aligned with the screw and tightened. The screw moves forward along the second limiting hole 4235 until it disengages from the second limiting hole 4235.

[0051] The inner diameters of the first limiting hole 4224 and the second limiting hole 4235 match the size of the screw. Therefore, screw limiting components 42 with different inner diameter models of the first limiting hole 4224 and the second limiting hole 4235 can be set to adapt to screws of different sizes. The screw limiting component 42 is detachably inserted into the slide plate 41. Each time when in use, just replace the screw limiting component 42 of the corresponding model.

[0052] It should be noted that the upper part of the first screw jaw 422 and the second screw jaw 423 is the working position, and the lower part is the waiting position. By rotating the switching plate 421, the first screw jaw 422 and the second screw jaw 423 can be switched from the working position to the waiting position (or from the waiting position to the working position). As Figure 11 shown, the first screw jaw 422 is in the working position and the second screw jaw 423 is in the waiting position; as Figure 12 shown, the second screw jaw 423 is in the working position and the first screw jaw 422 is in the waiting position.

[0053] During assembly, the electric screwdriver 3 and the copper nose on the wire limiting clip 43 need to be adjusted to align with the screw in the working position.

[0054] The switching plate 421 is provided with a first guiding groove 4211 and a second guiding groove 4212 at the corresponding positions of the first limiting hole 4224 and the second limiting hole 4235. The sizes of the first guiding groove 4211 and the second guiding groove 4212 match the outer shell of the electric screwdriver 3. When the electric screwdriver 3 moves to fit with the first guiding groove 4211 and the second guiding groove 4212, the electric screwdriver 3 will be aligned with the centers of the first limiting hole 4224 and the second limiting hole 4235. This design can quickly adjust the alignment of the electric screwdriver 3 with the screw and the copper nose.

[0055] The working process of the present invention is as follows:

[0056] S1: Observe whether the terminal of the electrical component to be wired is a counterbore or a blind hole. If it is a blind hole, uniformly switch the first screw jaw 422 to the working position. If it is a counterbore, uniformly switch the second screw jaw 423 to the working position;

[0057] S2: Fix multiple wires to the wire position-limiting clip 43 at one time, and then install the screws into the first screw clamping jaw 422 or the second screw clamping jaw 423 in the working position;

[0058] S3: Adjust the positions of the wires to align the copper lugs at the ends of the wires with the screws in the working position one by one;

[0059] S4: Move the sliding plate 41 to make the positions of the screw position-limiting assembly 42 and the wire position-limiting clip 43 correspond to the positions of the wiring terminals of the electrical components one by one;

[0060] S5: Place the adjusted copper lugs into the wiring openings of the wiring terminals from below, and at the same time make the first screw clamping jaw 422 or the second screw clamping jaw 423 in the working position abut against the screw mounting holes of the wiring terminals;

[0061] S6: Adjust the electric screwdriver 3 to align with the screw through the fine-tuning assembly 22, then, through the feeding assembly 21, move the electric screwdriver 3 forward to fit with the screw, and then start the electric screwdriver 3 to screw the screw;

[0062] S7: After screwing the screw, then, through the feeding assembly 21, move the electric screwdriver 3 backward to withdraw from the wiring terminal, and then adjust the electric screwdriver 3 to align with the next screw to be tightened through the fine-tuning assembly 22;

[0063] S8: Repeat the processes of S6 and S7 until all the wires on one electrical component are assembled.

[0064] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
