Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to fire connection operation equipment and a control method thereof. Background Art

[0002] The rapid development of the national economy has put forward higher requirements for power supply reliability. On the one hand, with the vigorous development of the power industry, the current dependence of government agencies, factories, mines and people's lives on electricity is increasing. On the other hand, power expansion, equipment maintenance, fault repair, etc. have to be carried out by power outages, which seriously affects residents' lives and industrial and agricultural production. For this reason, the power grid company has an increasingly urgent need for live work (non-stop work) to reduce the number of power outages and enhance the ability of live work. The power grid company requires that the work carried out on the distribution line must follow the principle of "no power outage", making the live work of the distribution network a development trend in the industry.

[0003] Live distribution network work is one of the main work items in live operation, which requires connecting one end of the drainage line to the high-voltage busbar under energized condition.

[0004] The drain wire is a common power system equipment, and its main function is to shunt or guide extra current to prevent other components from being damaged by overload or arcing. Due to its good insulation and protection, the drain wire can also carry and isolate current to ensure the safe operation of other power equipment. In the voltage distribution devices of power plants and substations at all levels, the busbar is a conductor that connects large electrical equipment such as generators and transformers with various electrical devices to build a bridge. It has the function of collecting, transmitting and distributing electrical energy. The bridge role played by the busbar is the basis for the normal operation of the power system.

[0005] In the live connection operation of the distribution network, one end of the drainage wire at the auxiliary support of the high-voltage power pole needs to be connected to the high-altitude busbar with a stripped length, and the other end of the drainage wire, i.e. the root, remains fixed at the auxiliary support. The drainage wire is connected to the busbar and fixed by the live wire clamp to achieve the conduction between the drainage wire and the busbar.

[0006] The wire stripper of the current fire connection equipment rotates and moves horizontally when stripping the wire, and the entire fire connection equipment needs to move horizontally with the wire stripper. After the stripping is completed, the entire fire connection equipment needs to continue to move horizontally so that the wire clamp fire connection device moves horizontally to the stripping section of the busbar.

[0007] The movement of the entire fire-connection operation equipment requires a large space for the fire-connection operation. For complex operation scenes, such as when there are trees blocking the operation or when multiple split lines form a complex cable network, the movement of the fire-connection operation equipment is easily restricted, resulting in poor adaptability. In addition, the movement of the entire fire-connection operation equipment will also prolong the operation time and affect the operation efficiency.

[0008] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0009] In view of the problems in the prior art, the purpose of the present invention is to provide fire-connecting operation equipment and a control method thereof, which overcomes the technical problems of poor environmental adaptability and low fire-connecting operation efficiency of fire-connecting operation equipment in other related technologies.

[0010] The present disclosure provides a fire connection operation device, which includes:

[0011] A base, on which a base busbar clamp is provided, and the base has a receiving space;

[0012] A wire stripper and a first driving mechanism matched therewith are located in the accommodating space, wherein the first driving mechanism has a first translation output end, and the first translation output end is rotationally connected to the wire stripper. The first driving mechanism is configured to drive the wire stripper to move between a first position and a second position along a first direction through the first translation output end, and output a drag force to the wire stripper through the first translation output end during the cyclic feed stage of the wire stripper, so that the wire stripper strips the wire in situ, and output a synchronous linear motion corresponding to the translation motion to the wire stripper through the first translation output end during the rotational translation stripping stage of the wire stripper;

[0013] A wire clamp fire connector mounted on a base and a second driving mechanism cooperating therewith, wherein the second driving mechanism is configured to drive the wire clamp fire connector to move between a first position and a third position along a second direction relative to the base.

[0014] The present disclosure also provides a method for controlling a fire connection operation of a fire connection operation device based on any of the above embodiments, which includes:

[0015] When the busbar is located in the stripping space of the wire stripper and the clamping space of the base busbar clamp, the base busbar clamp is controlled to clamp the busbar;

[0016] Based on the current wire stripping starting position corresponding to the first position, the wire stripper is controlled to perform a wire stripping operation. The wire stripping operation includes a cyclic feed stage and a rotational translational stripping stage. In the cyclic feed stage, the first driving mechanism is controlled to output a drag force to the wire stripper through the first translational output end, so that the wire stripper strips the wire in situ. In the rotational translational stripping stage, the first driving mechanism is controlled to output a synchronous linear motion corresponding to the translation of the wire stripper through the first translational output end until the wire stripping end position is reached, so as to obtain a busbar stripping segment corresponding to the position interval between the wire stripping starting position and the wire stripping end position.

[0017] After obtaining the busbar stripping section, controlling the first driving mechanism to drive the wire stripper to move along the first direction to the second position, and controlling the second driving mechanism to control the wire clamp connector carrying the wire clamp to be installed to move from the third position to the first position;

[0018] When the wire clamp connector is located at the first position, the wire clamp connector is controlled to install the wire clamp to be installed and the busbar stripping section.

[0019] The fire connection operation equipment and control method thereof of the present invention have the following advantages:

[0020] The fire connection operation equipment includes a base busbar clamp, and the base has a storage space, forming an environmentally controllable and stable operation scene in a complex and uncontrollable surrounding environment. The wire stripper is located in the storage space and a first driving mechanism is set corresponding to the wire stripper. The wire clamp fire connection device and the second driving mechanism are both installed with the base, so that the wire stripper and the wire clamp fire connection device are integrated in the fire connection operation equipment at the same time. On the one hand, the first driving mechanism is used to drive the wire stripper to transfer to the first position before the wire stripping operation begins, and drive the wire stripper to transfer to the second position after the wire stripping operation is completed. On the other hand, the first driving mechanism outputs a synchronous linear motion with the translational motion of the wire stripper along the busbar during the wire stripping operation of the wire stripper, so that the wire stripper can be smoothly translated during the wire stripping process. After the wire stripping operation is completed, the wire stripper is transferred to the second position, and the second driving mechanism is controlled to drive the wire clamp fire connection device to transfer to the first position, and the wire clamp installation operation is completed. During the wire stripping operation process, the wire stripper transfer process, and the wire clamp installation process, the base busbar clamp always keeps the busbar clamped to maintain the stability of the operation. Moreover, during the wire stripping operation of the wire stripper and the wire clamp installation process of the wire clamp fire connector, the fire connection operation equipment as a whole does not need to be horizontally translated relative to the busbar, so the base busbar clamp does not need to loosen the busbar, so that the wire stripping operation and the wire clamp installation process are both carried out within the base accommodation space. Since the fire connection operation equipment itself does not need to be moved, the obstructions in the working environment will not hinder the operation process of the fire connection operation equipment, so that the fire connection operation equipment of this embodiment has good environmental adaptability. At the same time, the fire connection operation equipment does not need to be moved during the operation process, which can relatively reduce the fire connection operation time and improve the efficiency of the fire connection operation.

[0021] In addition, since the base busbar clamp of this embodiment always keeps the busbar clamped during the operation and always maintains the clamping force on the busbar, the occurrence of the wire harness spinning can be reduced, which helps to smoothly carry out the wire stripping operation.

[0022] Furthermore, for weathered lines, the wire skin is prone to powderization. Since the fire-jointing equipment always remains in place during the fire-jointing operation, it can avoid friction on the weathered line and the generation of a large amount of debris. A large amount of debris can easily block the sensors in the fire-jointing equipment, affecting the accuracy of the sensors and increasing the risk of operational abnormalities.

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0038] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0039] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present application. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0040] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0041] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

[0042] It should be understood that when a component is referred to as being “on another component,” “connected to another component,” “coupled to another component,” or “contacting another component,” it can be directly on, connected to, coupled to, or contacting the other component, or intervening components may be present. In contrast, when a component is referred to as being “directly on another component,” “directly connected to,” “directly coupled to,” or “directly contacting” another component, there are no intervening components present.

[0043] In addition, the accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted.

[0044] The embodiment of the present disclosure provides a wiring operation device that can automatically perform wire stripping operations and busbar clamp installation operations. Figure 1 and Figure 2 As shown, the fire connection equipment may include:

[0045] A base 1, on which a base busbar clamp 5 is provided. Exemplarily, the base busbar clamp 5 includes a first busbar clamp 51 and a second busbar clamp 52. The base 1 has an accommodation space 1a. The first busbar clamp 51 and the second busbar clamp 52 are respectively located at two ends of the accommodation space 1a along the first direction AA';

[0046] The wire stripper 2 and the first driving mechanism 21 ( Figure 1The first driving mechanism 21 has a first translation output end 21a, and the first translation output end 21a is rotationally connected to the wire stripper 2. The first driving mechanism 21 is configured to drive the wire stripper 2 to move between the first position w1 and the second position w2 along the first direction AA', and output a drag force to the wire stripper 2 through the first translation output end 21a during the cyclic feed stage of the wire stripper 2, so that the wire stripper 2 can strip the wire in situ as much as possible, and output a synchronous linear motion corresponding to the translation motion of the wire stripper 2 through the first translation output end 21a during the rotation and translation stripping stage of the wire stripper 2 (described in detail in the fire connection operation control method later);

[0047] The wire clamp fire catcher 4 mounted on the base 1 and the second driving mechanism 42 matched therewith are configured to drive the wire clamp fire catcher 4 to the first position w1 and the third position w3 ( Figure 1 The third position w3 is lower than the first position w1 along the second direction BB', and when the wire stripper 2 is at the first position w1, the wire clamp fire connector is at the third position w3.

[0048] Among them, the wire stripper 2 and the first translational output end 21a are rotationally connected, and the rotating shaft of the rotational connection is the rotating shaft of the wire stripper 2. Therefore, on the one hand, the first translational output end 21a can output a linear driving force to the wire stripper 2. On the other hand, during the rotation process of the wire stripping operation, the wire stripper 2 can rotate relative to the first translational output end 21a to ensure the normal wire stripping operation of the wire stripper 2.

[0049] like Figure 2 As shown, in the initial state, the wire stripper 2 is located at the first position w1, and the wire clamp fire connector 4 is located at the third position w3, that is, located below the wire stripper 2. The fire connector operation equipment is online, the busbar enters the stripping space 2a of the wire stripper 2, and the first busbar clamp 51 and the second busbar clamp 52 both clamp the busbar, and the wire stripper 2 is controlled to perform a stripping operation on the busbar.

[0050] In the cyclic feeding stage, since the wire stripper 2 has a tendency to translate relative to the busbar when rotating, the first driving mechanism 21 is controlled to output a reverse drag force to the wire stripper 2 for the translation tendency, so that the wire stripper 2 can complete the cyclic feeding operation as much as possible in situ until the wire core is exposed, that is, the wire stripper 2 does not translate relative to the busbar as much as possible. In the rotational translational stripping stage after the cyclic feeding stage, the wire stripper 2 needs to maintain effective translation during the rotation process. At this time, the first driving mechanism 21 is controlled to output a synchronous linear motion corresponding to the translational motion of the wire stripper 2 to avoid causing resistance to the translational motion of the wire stripper 2, and ensure that the wire stripper 2 rotates and translates until the entire stripping operation is completed;

[0051] Combination Figure 2 and Figure 3 As shown, after the stripping operation is completed, the busbar exposes the busbar stripping section at the first position w1. Afterwards, the first busbar clamp 51 and the second busbar clamp 52 are kept clamping the busbar, and the first driving mechanism 21 is controlled to drive the stripper 2 to translate along the first direction AA' to the second position w2, freeing up space for the wire clamp fire connector 4 to move upward. At the same time, the busbar stripping section is just located above the wire clamp fire connector 4, and its position is controllable. There is no need to calibrate the position of the wire clamp fire connector 4 relative to the busbar stripping section, thereby improving the overall fire connection operation efficiency.

[0052] Combination Figure 3 and Figure 4 As shown, the second driving mechanism 42 is controlled to drive the wire clamp fire connector 4 to rise to the first position w1. At this time, when the wire clamp fire connector 4 carries the wire clamp, at the first position w1, the bare wire segment of the busbar 100 ( Figure 4 The wire (covered by the wire clamp) is pushed into the wire clamp, and the wire clamp fire connector 4 is further controlled to install the wire clamp and the busbar bare wire segment to complete the fire connection operation.

[0053] Finally, the above-mentioned fire-fighting equipment shall be evacuated.

[0054] When using the fire connection operation equipment of this embodiment, during the wire stripping operation, the wire stripper transfer process, and the wire clamp installation process, the base busbar clamp always keeps the busbar clamped to maintain the operation stability. Moreover, during the wire stripping operation of the wire stripper 2 and the wire clamp installation process of the wire clamp fire connector 4, the fire connection operation equipment as a whole does not need to be translated laterally relative to the busbar, so the base busbar clamp does not need to loosen the busbar, so that the wire stripping operation and the wire clamp installation process are both carried out in the accommodating space 1a of the base 1. Since the fire connection operation equipment itself does not need to be moved, the obstructions in the working environment will not hinder the operation process of the fire connection operation equipment, so that the fire connection operation equipment of this embodiment has good environmental adaptability. At the same time, the fire connection operation equipment does not need to be moved during the operation process, which can relatively reduce the fire connection operation time and improve the efficiency of the fire connection operation.

[0055] In addition, if Figure 4 As shown, since the base busbar clamp 5 of this embodiment always keeps the busbar 100 clamped during operation, a large clamping force can be always maintained on the busbar 100, which can reduce the occurrence of the busbar spinning and help the wire stripping operation go smoothly.

[0056] Furthermore, for weathered lines, since the fire-joining equipment always remains in place during the fire-joining process, it can avoid friction on the weathered lines and cause a large amount of debris. A large amount of debris can easily block the sensors in the fire-joining equipment, affecting the accuracy of the sensors and increasing the risk of abnormal operation. For example, a large amount of debris blocks the skin-core detection sensor, and the cutter continues to cut after the core is stripped, which can easily cause excessive damage to the core.

[0057] In this embodiment, if Figure 2-4 As shown, the third position w3 is located below the first position w1, and the second direction BB' is perpendicular to the first direction AA'. The wire clamp fire connector 4 is located below the wire stripper 2 in the initial position. After the wire stripper 2 completes the wire stripping, it stops at the second position w2. The busbar stripping section is directly opposite to the wire clamp in the lower wire clamp fire connector 4. The lower wire clamp fire connector 4 moves upward, and the busbar stripping section enters the wire clamp. In this way, the wire stripping operation and the wire clamp installation operation space are highly integrated, and the overall operation space is small, which can reduce the risk of touching surrounding lines or obstacles and improve operation safety.

[0058] like Figure 4 As shown, the first driving mechanism 21 includes:

[0059] A first rotating motor (obstructed and not visible in the figure) has a first motor output end (obstructed and not visible in the figure);

[0060] A first transmission mechanism 212 having a first rotation input end 21b and a first translation output end 21a, connected to the first motor output end through the first rotation input end 21b to input rotational motion;

[0061] The first transmission mechanism 212 is configured to convert the rotational motion of the first rotation input end 21 b into a linear motion of the first translation output end 21 a along the first direction AA′.

[0062] In this embodiment, the first rotary motor is controlled to output a rotary motion, and further realizes forward and reverse rotation by changing the direction of the input current, thereby providing a linear driving force in two opposite directions along the first direction AA' for the wire stripper 2. Therefore, by controlling the parameters such as the on / off of the first rotary motor, the direction and magnitude of the current, the translation of the wire stripper 2 can be precisely controlled.

[0063] In the embodiment of the present disclosure, the first transmission mechanism 212 is used to convert the rotational motion from the first rotary motor into the linear motion of the wire stripper 2, thereby ensuring the feasibility and controllability of the first drive mechanism 21 combined with the first rotary motor. In addition, the specific structure of the first transmission mechanism 212 can be reasonably selected according to the installation environment to ensure the adaptability of the installation environment.

[0064] In the embodiments of the present disclosure, Figure 4As shown, the first transmission mechanism 212 is a screw transmission mechanism, comprising: a first screw 2121 extending along a first direction AA' and a first sliding member 2122 installed with the first screw 2121 through a screw transmission pair, and the first sliding member 2122 is configured to limit the rotation relative to the first screw 2121;

[0065] The first rotation input end 21 b is formed on the first screw rod 2121 , and the first translation output end 21 a is formed on the first sliding member 2122 .

[0066] like Figure 4 As shown, the wire stripper 2 and the first sliding member 2122 are installed via a rotational connection, and the wire stripper 2 moves synchronously with the first sliding member 2122 and can perform rotational motion relative to the first sliding member 2122. Since the first sliding member 2122 is rotationally limited relative to the first screw rod 2121, the rotational motion of the first screw rod 2121 is converted into the linear motion of the first sliding member 2122 through the screw rod transmission pair.

[0067] The screw transmission pair is configured such that the first sliding member 2122 is sleeved on the first screw 2121, and is threadedly connected to the corresponding threaded section on the first screw 2121, and is rotationally limited relative to the first screw 2121. In addition, balls may be filled between the first sliding member 2122 and the first screw 2121 to form a ball screw transmission mechanism.

[0068] In one embodiment, in combination Figure 5 As shown, Figure 5 The wire stripper is not shown in the figure, and the first transmission mechanism 212 also includes a first guide rail 2123, and the first guide rail 2123 is arranged in parallel with the first screw rod 2121. Correspondingly, the first sliding member 2122 is provided with a slide groove 21d that cooperates with the first guide rail 2123. Specifically, the first sliding member 2122 is fitted with the first guide rail 2123 through the slide groove 21d to form a slide rail and slide groove structure, which can realize the rotation limit of the first sliding member 2122 on the one hand, and realize the wire stripper 2 (such as Figure 4 ) for stable translation.

[0069] In the embodiments of the present disclosure, Figure 4 and Figure 5 As shown, the first screw rod 2121 is installed on the outside of the base 1, and its two ends are fixed and rotatably installed, which can avoid the wire stripper 2 ( Figure 5 The movement of the first element (not shown) along the first direction AA' forms a barrier.

[0070] The first sliding member 2122 includes a sliding portion 21221 and a wire stripper mounting portion 21222 connected to the sliding portion 21221. The sliding portion 21221 is connected to the first screw rod 2121 through a screw rod transmission pair. The wire stripper mounting portion 21222 is located above the base 1 and has a second through groove 21e. The wire stripper 2 is installed with the wire stripper mounting portion 21222 by a rotation connection (such as Figure 4 As shown), it is exemplarily located on one side of the wire stripper mounting portion 21222 along the first direction AA'.

[0071] In this way, Figure 4 As shown, the wire stripper mounting portion 21222 provides a mounting support structure for the wire stripper 2. The second through slot 21e is arranged opposite to the wire stripping space 2a along the first direction AA', and when the busbar 100 is inserted into the wire stripping space 2a from top to bottom, it is also inserted into the second through slot 21e.

[0072] In an optional manner, the first driving mechanism can directly select a linear motor, an electric push rod, a linear cylinder, etc., which is not limited here.

[0073] like Figure 5 As shown, in the embodiment of the present disclosure, the base 1 includes a first support portion 11 and a second support portion 12 located at both ends along the first direction AA' (the first support portion 11 is located at one end close to the first position w1, and the second support portion 12 is located at one end close to the second position w2;

[0074] A first through slot 11 a is disposed on the top of the first support portion 11 and passes through the first support portion 11 along the first direction AA′. The first busbar clamp 51 is disposed above the first through slot 11 a.

[0075] like Figure 6 As shown, Figure 6 for Figure 5 The side view of the fire connection equipment shown in the figure after removing the outer shell, specifically along the Figure 5 As shown in the side view from the first support portion 11 in the first direction AA', the first busbar clamp 51 includes two first clamping claws 511 arranged opposite to each other along the third direction CC' to form a first clamping space 51a. When the first busbar clamp 51 is in an open state, the first clamping space 51a of the first busbar clamp 51 is connected to the first through groove 11a in the depth direction, that is, it is connected to the first through groove 11a below.

[0076] The fire connection operation equipment further includes a third driving mechanism 63, which is configured to controllably drive the first clamping jaws 511 on both sides to switch between the clamping position and the open position. Meanwhile, the third driving mechanism 63 and the first through slot 11a have no overlapping area along the first direction AA'.

[0077] During operation, the first busbar clamp 51 is used to clamp the busbar during the stripping process to prevent the busbar from loosening and ensure the stability of the busbar during the stripping process. The clamping position refers to the first clamping jaws 511 on both sides clamping against each other, at which time the busbar can be clamped. The open position refers to the first clamping jaws 511 on both sides being separated.

[0078] During the operation, the fire connection operation equipment carries the drain wire through the wire clamp fire connector 4 and lifts it to the busbar position. During this process, the drain wire passes through the first through groove 11a from the outside. During the wire stripping operation, the first busbar clamp 51 is in the clamping position, clamping the busbar, and the drain wire remains in the initial position. When the wire stripping is completed, the wire stripper 2 is translated to the second position w2, the wire clamp fire connector 4 rises to the first position w1, and the drain wire moves upward accordingly. At this time, the first busbar clamp 51 still remains in the clamping position. When the wire clamp fire connector 4 completes the installation of the busbar and the wire clamp, the first busbar clamp 51 is controlled to switch to the open position. Finally, the fire connection operation equipment is evacuated from top to bottom. During this process, the busbar first detaches from the first clamping space 51a. Next, the drainage wire escapes from the first through slot 11a and the top wire entrance of the first wire clamping space 51a. During this process, since the third driving mechanism 63 and the first through slot 11a have no overlapping area along the first direction AA', the drainage wire will not be blocked in the process of escaping upward from the top wire entrance of the first through slot 11a and can escape smoothly.

[0079] In this embodiment, by providing the third driving mechanism 63 corresponding to the first busbar clamp 51, the switching of the clamping position and the opening position of the first busbar clamp 51 can be automatically controlled, thereby realizing automatic control with high control accuracy and high operating efficiency.

[0080] In the embodiments of the present disclosure, Figure 6 As shown, the third driving mechanism 63 includes:

[0081] The third rotary motor 630 has a third motor output terminal 63a. Exemplarily, the third rotary motor 630 is disposed on the bottom side wall of the base 1 and does not block the first through slot 11a above;

[0082] The transmission rod 631 is located outside the bottom of the first through slot 11a and extends along the third direction CC', is installed with the third motor output end 63a, and is configured to input the rotational motion of the third motor output end 63a;

[0083] The first side of the first through groove 11a is located along the third direction CC' (exemplarily as Figure 6 The first screw transmission mechanism 632 and the first belt transmission mechanism 633 along the third direction CC' are located on the second side of the first through groove 11a (exemplarily as Figure 6 a second screw transmission mechanism 634 and a second belt transmission mechanism 635 on the right side of the device;

[0084] The first belt transmission mechanism 633 couples the transmission rod 631 and the first screw transmission mechanism 632 and is configured to transmit the rotational motion of the transmission rod 631 to the first screw transmission mechanism 632;

[0085] The first screw transmission mechanism 632 couples the first belt transmission mechanism 633 and the first clamping claw 511 on the first side, and is configured to convert the rotational motion output by the first belt transmission mechanism 633 into a linear motion of the first clamping claw 511 on the first side along the third direction CC′;

[0086] The second belt transmission mechanism 635 couples the second screw transmission mechanism 634 and the transmission rod 631 and is configured to transmit the rotational motion of the transmission rod 631 to the second screw transmission mechanism 634;

[0087] The second screw transmission mechanism 634 couples the second belt transmission mechanism 635 and the first clamping jaw 511 on the second side, and is configured to convert the rotational motion output by the second belt transmission mechanism 635 into a linear motion of the first clamping jaw 511 on the second side in the opposite direction of the third direction CC′.

[0088] In this embodiment, the third rotating motor 630 is controlled to output a rotational motion, which is transmitted to the transmission rod 631. The transmission rod 631 synchronously transmits the rotational motion to the first belt transmission mechanism 633 and the second belt transmission mechanism 635 on both sides. Then the first screw transmission mechanism 632 and the second screw transmission mechanism 634 are respectively input with the rotational motion and output linear motion in opposite directions. Then, the first clamping jaws 511 on both sides are driven to move toward each other to the clamping position or move away from each other to the open position.

[0089] In this embodiment, the first screw transmission mechanism 632 and the first belt transmission mechanism 633 are located on the first side of the first through slot 11a, and the first belt transmission mechanism 633 couples the transmission rod 631 and the first screw transmission mechanism 632 from top to bottom to achieve rotational motion transmission and rotate with the first through slot 11a along the first direction AA' (such as Figure 5 The second screw transmission mechanism 634 and the second belt transmission mechanism 635 are located on the second side of the first through slot 11a. The second belt transmission mechanism 635 couples the transmission rod 631 and the second screw transmission mechanism 634 from top to bottom to achieve rotational motion transmission and no overlap with the first through slot 11a along the first direction AA'. This embodiment achieves no overlapping area between the third driving mechanism 63 and the first through slot 11a along the first direction AA', avoiding obstruction and interference when the drainage line is separated from the first through slot 11a upward.

[0090] In an optional embodiment, a third motor gear 6301 is installed at the third motor output end 63a, a transmission rod gear 6311 is installed on the transmission rod 631, and the third motor gear 6301 is meshed with the transmission rod gear 6311 to transmit rotational motion.

[0091] In one implementation, a first driving wheel 6331 is coaxially installed at one end of the transmission rod 631 close to the first side, a first driven wheel 6332 is installed at the top position of the first support portion 11, and a first transmission belt 6333 is tensionedly mounted on the first driving wheel 6331 and the first driven wheel 6332, which are assembled together into a first belt transmission mechanism 633.

[0092] In one implementation, a first pulley gear 641 coaxially connected to the first driven wheel 6332 is coaxially installed at the top position of the first support portion 11, and a first screw gear 6321 is coaxially installed on the first transmission screw 6320 in the first screw transmission mechanism 632, and the first screw gear 6321 is meshed with the first pulley gear 641 to transmit rotational motion.

[0093] As an implementation, the first screw transmission mechanism 632 includes the first transmission screw 6320 extending along the third direction CC', and the first clamping jaw 511 on the first side is assembled with the first transmission screw 6320 through a screw transmission pair, and is configured to be rotationally limited relative to the first transmission screw 6320. Therefore, the rotational motion of the first transmission screw 6320 can be converted into the linear motion of the first clamping jaw 511 along the first transmission screw 6320.

[0094] As an implementation method, a second driving wheel 6351 is coaxially installed at one end of the transmission rod 631 close to the second side, the second driving wheel 6351 is coaxial with the transmission rod gear 6311, and a second driven wheel 6352 is installed at the top position of the first support part 11. The second transmission belt 6353 is tensionedly mounted on the second driving wheel 6351 and the second driven wheel 6352, which are assembled together into a second belt transmission mechanism 635.

[0095] In one implementation, a second pulley gear 642 coaxially connected to the second driven wheel 6352 is installed at the top position of the first support portion 11, and a second screw gear 6341 is coaxially installed on the second transmission screw 6340 in the second screw transmission mechanism 634, and the second screw gear 6341 is meshed with the second pulley gear 642 to transmit rotational motion.

[0096] As an implementation method, the second screw transmission mechanism 634 includes the second transmission screw 6340 extending along the third direction CC', and the first clamping jaw 511 on the second side is assembled with the second transmission screw 6340 through a screw transmission pair, and is set to be rotationally limited relative to the second transmission screw 6340. Therefore, the rotational movement of the second transmission screw 6340 can be converted into the linear movement of the first clamping jaw 511 along the second transmission screw 6340.

[0097] In the embodiment of the present disclosure, in order to achieve simultaneous directional movement of the first clamping jaws 511 on both sides, the screw threads on the first transmission screw 6320 and the second transmission screw 6340 are designed to have opposite directions. Then, when rotational movement in the same rotational direction is input, the first clamping jaws 511 on both sides can translate in opposite directions.

[0098] In an optional embodiment, the number of transmission stages of the gear transmission mechanism between the screw transmission mechanism and the belt transmission mechanism on both sides can be adjusted, exemplarily to primary transmission and secondary transmission, respectively, so that the rotational motion input by the first transmission screw and the second transmission screw are opposite. At this time, the spiral directions of the threads on the first transmission screw and the second transmission screw are the same, but the directions of the final output linear motion are opposite.

[0099] In the embodiment of the present disclosure, a single third rotary motor 630 is used to realize the clamping and opening control of the first clamping jaws 511 on both sides, and the control accuracy of the single third rotary motor 630 is relatively higher. In an optional manner, the third driving mechanism can also be designed to set a rotary motor on at least one side and cooperate with a screw transmission mechanism to individually control the first clamping jaws on the same side.

[0100] In the embodiments of the present disclosure, Figure 6 As shown, a micro switch 65 is installed on the first support portion 11, and the micro switch 65 is located on the side of the first clamping jaw 511 on the second side away from the first clamping jaw 511 on the first side along the third direction CC'. The micro switch 65 is configured to generate a closing signal when the first clamping jaw 511 on the second side abuts in the open position. The closing signal is used to trigger the control of powering off the third rotating motor 630, so that the first clamping jaws 511 on both sides stop in the open position, thereby realizing precise control of the first busbar clamp 51.

[0101] In the embodiments of the present disclosure, reference Figure 7 , Figure 7 for Figure 5 The side view of the fire connection equipment shown in the figure after removing the outer shell, specifically along the Figure 5 The side view of the second support portion 12 in the first direction AA' is shown, and the second busbar clamp 52 is arranged above the second support portion 12 and is connected to the first busbar clamp 51 (such as Figure 5The second busbar clamp 52 includes two second clamping jaws 521 arranged opposite to each other along the third direction CC' to form a second clamping space 52a. The second clamping space 52a is opposite to the stripping space 2a along the first direction AA', wherein the third direction CC' and the second direction BB' (as shown) are opposite to each other. Figure 1 As shown) and the first direction AA' are perpendicular to each other.

[0102] The fire-joining operation equipment also includes a fourth driving mechanism 54, which is configured to controllably drive the second clamping jaws 521 on both sides to switch between a clamping position and an open position.

[0103] During the operation, the second busbar clamp 52 is used to clamp the busbar during the stripping process to prevent the busbar from loosening and ensure the stability of the busbar during the stripping process. Figure 4 As shown, the first busbar clamp 51 and the second busbar clamp 52 clamp the busbar 100 at both ends respectively, which can better maintain the stability of the busbar 100 during the stripping process.

[0104] In the embodiments of the present disclosure, Figure 7 As shown, the fourth driving mechanism 54 includes:

[0105] The fourth rotating motor 541 has a fourth motor output terminal 54a;

[0106] The fourth transmission mechanism 542 comprises:

[0107] A fourth screw rod 5421 extending along the third direction CC' is divided into two threaded sections with opposite spiral directions along the third direction CC'. The fourth screw rod 5421 is connected to the output end 54a of the fourth motor to input rotational motion;

[0108] The fourth sliding members 5422 on both sides are respectively assembled with the two threaded sections through the screw transmission pair. The fourth sliding member 5422 is set to limit the rotation relative to the fourth screw 5421. The second clamping jaws 521 on both sides are respectively installed with the fourth sliding members 5422 on both sides.

[0109] Since the two threaded sections of the fourth screw rod 5421 have opposite spiral directions, when the fourth screw rod 5421 inputs a rotational motion, the two fourth sliding members 5422 thereon move in opposite directions, that is, move toward each other or move away from each other at the same time.

[0110] During operation, the fourth rotary motor 541 is controlled to output rotary motion, and the fourth transmission mechanism 542 is a screw transmission mechanism, which converts the above rotary motion into simultaneous movement of the fourth sliding members 5422 on both sides toward each other or away from each other, and finally drives the second clamping jaws 521 on both sides to move toward each other or away from each other. By changing the input current direction of the fourth rotary motor 541, forward and reverse rotation can be achieved, and finally the second clamping jaws 521 on both sides are driven to translate to the clamping position and move in the opposite direction to the open position. Therefore, by controlling the parameters such as the power on and off of the fourth rotary motor 541, the direction and size of the current, etc., the second clamping jaws 521 on both sides can be accurately controlled.

[0111] In this embodiment, the second clamping jaws 521 on both sides can move in the opposite direction along the third direction CC' to reach the clamping position or the open position through a single fourth screw rod 5421, which has a simple structure and occupies a small space. Combined with a single fourth rotating motor 541, the control accuracy of the second busbar clamp 52 is higher.

[0112] In one embodiment, the fourth motor output end 54a of the fourth rotating motor 541 is equipped with a fourth motor gear 5411 to input rotational motion, and the fourth screw rod 5421 is equipped with a coaxial fourth screw gear 5423. The fourth motor gear 5411 is meshed with the fourth screw gear 5423 to form a gear transmission mechanism, and finally the rotational motion is input to the fourth screw rod 5421 through the fourth screw gear 5423.

[0113] Optionally, a belt transmission mechanism may be coupled between the output end of the fourth motor and the fourth lead screw to replace the gear transmission mechanism.

[0114] In an optional embodiment, the fourth drive mechanism is separately configured on the second clamping jaw on each side to control the second clamping jaw on each side separately. In this case, the fourth drive mechanism can use a linear motor, an electric push rod or a linear cylinder.

[0115] In the above embodiment, Figure 5 As shown, the base busbar clamp 5 includes a first busbar clamp 51 and a second busbar clamp 52, that is, busbar clamps are provided at both ends of the base 1 along the first direction AA', which can ensure the stability of the fire connection operation equipment relative to the busbar during the operation, and also form a more balanced and tighter clamping force on the busbar during the stripping operation. In another embodiment, if space permits, multiple busbar clamps of other numbers can also be provided, which is not limited here.

[0116] In the embodiments of the present disclosure, Figure 8 As shown, the second driving mechanism 42 includes:

[0117] The second rotating motor 421 has a second motor output terminal 42a;

[0118] The second transmission mechanism 422 comprises:

[0119] The second screw rod 4221 extending along the second direction BB' is connected to the second motor output end 42a to input rotational motion;

[0120] The second sliding member 4222 is installed with the second screw rod 4221 through a screw rod transmission pair. The second sliding member 4222 is set to limit the rotation relative to the second screw rod 4221. The second sliding member 4222 is installed with the wire clamp igniter 4.

[0121] In this embodiment, the second rotary motor 421 is controlled to output a rotary motion and transmit it to the second screw rod 4221. The second transmission mechanism 422 is a screw transmission mechanism, the wire clamp fire catcher 4 is installed with the second sliding member 4222, and the wire clamp fire catcher 4 is synchronously translated with the second sliding member 4222. Since the second sliding member 4222 is rotationally limited relative to the second screw rod 4221, the rotary motion of the second screw rod 4221 is converted into the linear motion of the second sliding member 4222 through the screw transmission pair.

[0122] The screw transmission pair is configured such that the second sliding member 4222 is sleeved on the second screw 4221, and is threadedly connected to the corresponding threaded section on the second screw 4221, and is rotationally limited relative to the second screw 4221. In addition, balls may be filled between the second sliding member 4222 and the second screw 4221 to form a ball screw transmission mechanism.

[0123] During operation, the input current direction of the second rotary motor 421 is changed to realize forward and reverse rotation, and finally the wire clamp fire connector 4 is driven to move up and down between the first position w1 and the third position w3. Therefore, by controlling the parameters such as the on / off of the second rotary motor 421, the direction and size of the current, the lifting and lowering of the wire clamp fire connector 4 can be accurately controlled.

[0124] In the disclosed embodiment, the second transmission mechanism 422 is used to convert the rotational motion from the second rotary motor 421 into the linear motion of the wire clamp fire arrester 4, thereby ensuring the feasibility and controllability of the second drive mechanism 42 combined with the second rotary motor 421. In addition, the specific structure of the second transmission mechanism 422 can be reasonably selected according to the installation environment to ensure the adaptability to the installation environment.

[0125] In the embodiment of the present disclosure, the second transmission mechanism 422 may further include a second guide rail 4223 (eg Figure 1As shown in the figure, the second guide rail 4223 is arranged in parallel with the second screw rod 4221. Correspondingly, the second sliding member 4222 is provided with a slide groove (not shown in the figure) that cooperates with the second guide rail 4223. Specifically, the second sliding member 4222 is fitted with the second guide rail 4223 through the slide groove (which is blocked and invisible in the figure) to form a slide rail and slide groove structure, which can realize the rotation limit of the second sliding member 4222 on the one hand, and realize the stable lifting and lowering of the wire clamp fire arrester 4 on the other hand.

[0126] In the embodiments of the present disclosure, Figure 1 As shown, a first support portion 11 higher than the base 1 is provided at one end of the base 1 away from the second position w2, and a second screw rod 4221 ( Figure 1 The first support portion 11 provides a mounting support structure for the second driving mechanism 42.

[0127] In an optional manner, the second driving mechanism may also use an electric push rod, a linear motor or a linear cylinder, etc., which is not limited here.

[0128] In the embodiments of the present disclosure, Fig. 9 As shown, the wire clamp fire connector 4 includes a wire clamp placement portion 41 and a wire clamp screwing mechanism 43. The wire clamp screwing mechanism 43 is located outside the wire clamp placement portion 41 along the third direction CC'.

[0129] Combination Fig.10 As shown, the wire clamp screwing mechanism 43 includes a screwing sleeve 431 and a fifth driving mechanism 432 matched with the screwing sleeve 431, the screwing sleeve 431 points to the wire clamp placement portion 41 along the third direction CC', and the screwing sleeve 431 is configured to screw the pre-tightening bolt 45 on the wire clamp 44 to be installed placed in the wire clamp placement portion 41;

[0130] The fifth driving mechanism 432 is configured to drive the screwing sleeve 431 to rotate under control so as to screw the pre-tightening bolt 45 until the wire clamp to be installed reaches the clamping position.

[0131] During the connection operation, the stripped bare wire segment of the busbar is inserted into the wire clamp 44 to be installed. At this time, the fifth driving mechanism 432 is controlled to drive the screw sleeve 431 to screw the pre-tightening bolt 45 until the wire clamp 44 to be installed reaches the clamping position, which means that the wire clamps on both sides of the wire clamp 44 to be installed tightly clamp the bare wire segment of the busbar. Finally, the connection operation equipment is evacuated.

[0132] This implementation can realize automatic installation of the wire clamp and the busbar, and the connection efficiency is high.

[0133] In one embodiment, the fifth driving mechanism 432 includes a fifth rotary motor 4320, which provides a rotary power source. Exemplarily, the wire clamp fire arrester 4 includes four or other numbers of screw sleeves 431, the number of which is adapted to the number of pre-tightening bolts 45 in the wire clamp 44 to be installed, and the position of which is adapted to the position relationship of the pre-tightening bolts 45 in the wire clamp 44 to be installed. At this time, the fifth driving mechanism 432 may also include a gear transmission mechanism 4321, which is used to transmit the rotational motion of the fifth rotary motor 4320 to achieve synchronous screwing of all screw sleeves 431.

[0134] In the embodiments of the present disclosure, Fig. 9 and Fig.11 As shown, the wire clamp fire arrester 4 also includes:

[0135] The fire-receiving device base 40, the wire clamp placement portion 41 is fixedly arranged on the fire-receiving device base 40, and the wire clamp screwing mechanism 43 can move relative to the wire clamp placement portion 41 along the third direction CC';

[0136] The spring member 46 has two ends along the third direction CC' that are respectively connected to the wire clamp screwing mechanism 43 and the fire receiver base 40.

[0137] The spring member 46 is configured to place a wire clamp 44 (such as Fig.10 As shown) is in a stretched state, the screw sleeve 431 ( Fig.11 The pre-tightening bolt 45 (not shown) abuts against the wire clamp 44 to be installed until Fig.10 shown) is screwed into place.

[0138] In the embodiments of the present disclosure, Fig.11 As shown, the wire clamp fire connector 4 also includes a first buckle 491 arranged on the fire connector base 40 and a second buckle 492 arranged on the bottom of the wire clamp screwing mechanism 43.

[0139] Combination Fig.10 and Fig.11 As shown, before the fire connection operation, the wire clamp screwing mechanism 43 is translated outward until the second buckle 492 forms a snap fit with the first buckle 491. For example, the second buckle 492 is hooked on the first buckle 491, so that the wire clamp screwing mechanism 43 is fixed in place and the wire clamp placement space 41a (such as Fig. 9 As shown), at this time, the wire clamp 44 to be installed can be placed in the wire clamp placement space 41a ( Fig.11(not shown). During the outward movement of the wire clamp screwing mechanism 43, the spring member 46 is stretched. After the wire clamp 44 to be installed is placed in the wire clamp placement space 41a, the snap fit between the second buckle 492 and the first buckle 491 is released, and the wire clamp screwing mechanism 43 is subjected to the tensile elastic force of the spring member 46, so that the screwing sleeve 431 abuts against the bolt head of the pre-tightening bolt 45 in the wire clamp 44 to be installed, and the bolt head cooperates with the inner wall of the screwing sleeve 431. At this time, the spring member 46 is in a stretched state, so that the screwing sleeve 431 forms a certain pressure on the wire clamp 44 to be installed, which plays a certain stabilizing role on the wire clamp 44 to be installed, so that the wire clamp 44 to be installed is restricted in the wire clamp placement space 41a in the wire clamp placement portion 41, and the wire clamp 44 to be installed is prevented from falling off during the movement process and the wire stripping process.

[0140] During the screwing process, as the pre-tightening bolt 45 gradually moves inward along the third direction CC', the tensile elastic force of the spring member 46 is gradually released, but on the one hand, it can still provide lateral pressure on the wire clamp 44 to be installed, and on the other hand, the wire clamp screwing mechanism 43 moves inward with the pre-tightening bolt 45 as the elastic force of the spring member 46 is released, so that the screwing sleeve 431 and the bolt head of the pre-tightening bolt 45 are kept from being separated, thereby continuously providing effective screwing force. When screwed into place, the pre-tightening bolt 45 stops moving, at which time the elastic force of the spring member 46 is just released or still has a certain tensile elastic force, which is not limited.

[0141] like Fig.11 As shown, the spring member 46 is located at the bottom of the wire clamp placement portion 41, and hooks at both ends respectively hook the inner side surface of the fire receiver base 40 and the outer side surface of the wire clamp screwing mechanism 43 to achieve assembly.

[0142] In the embodiments of the present disclosure, Fig. 9 As shown, the wire clamp fire arrester 4 also includes:

[0143] Drainage wire fixture 47 (combined with Figure 8 As shown), fixed on the fire receiver base 40 ( Figure 8 is blocked and cannot be seen), and is located on the wire clip placement portion 41 and the first through groove 11a (see Figure 5 The drainage line clamp 47 includes a drainage line clamp space 47a ( Fig. 9 The drainage line clamp 47 of the middle drainage line clamp 47 is in the clamping position (the two sides of the drainage line clamp 471);

[0144] The sixth drive mechanism 48 (combined with Figure 8 As shown), cooperate with the drainage wire clamp 471 on at least one side, and is configured to be controlled to drive the drainage wire clamps 471 on both sides to switch between the clamping position and the open position.

[0145] During the fire connection operation, the drain wire clamp 47 is used to clamp the drain wire to prevent the drain wire from falling off during the dragging process, thereby ensuring the stability of the drain wire during the fire connection operation. Figure 8 ), the first support portion 11 is provided with a first through slot 11a (as shown Figure 6 As shown, the drainage wire passes through the first through slot 11a and is inserted into the wire clip 44 to be installed (see Fig.10 ) in the drainage wire channel 44a and is clamped by the drainage wire clamp 47.

[0146] In the embodiments of the present disclosure, Fig. 9 As shown, the sixth driving mechanism 48 includes:

[0147] A sixth rotating motor 481 having a sixth motor output terminal (not shown in the figure);

[0148] The sixth transmission mechanism 482 comprises:

[0149] A sixth screw rod 4821 extending along the third direction CC' is divided into two threaded sections with opposite spiral directions along the third direction CC'. The sixth screw rod 4821 is connected to the output end of the sixth motor to input rotational motion;

[0150] The sixth sliding members 4822 on both sides are assembled with the two threaded sections through a screw transmission pair (one side of the sixth sliding members is blocked and invisible), and the sixth sliding member 4822 is set to limit the rotation relative to the sixth screw rod 4821, and the drainage line clamps 471 on both sides are respectively installed with the sixth sliding members 4822 on both sides.

[0151] Since the two threaded sections of the sixth screw rod 4821 have opposite spiral directions, when the sixth screw rod 4821 inputs a rotational motion, the two sixth sliding members 4822 thereon move in opposite directions, that is, move toward each other or move away from each other at the same time.

[0152] During operation, the sixth rotary motor 481 is controlled to output rotary motion, and the sixth transmission mechanism 482 is a screw transmission mechanism, which converts the above rotary motion into simultaneous movement of the sixth sliding members 4822 on both sides toward each other or away from each other, and finally drives the drainage line clamps 471 on both sides to move toward each other or away from each other.

[0153] By changing the direction of the input current, the forward and reverse rotations are realized, and finally the drainage wire clamps 471 on both sides are driven to translate to the clamping position and move in the opposite direction to the open position. Therefore, by controlling the parameters such as the switch of the sixth rotary motor 481, the direction and magnitude of the current, etc., the drainage wire clamps 471 on both sides can be precisely controlled.

[0154] In this embodiment, the drainage wire clamps 471 on both sides can move in the opposite direction along the third direction CC' to reach the clamping position or the opening position through a single sixth screw rod 4821, which has a simple structure and occupies a small space. Combined with a single sixth rotating motor 481, the control accuracy of the drainage wire clamp 47 is higher.

[0155] For example, Figure 8 and Fig. 9 As shown, there are two groups of drainage line clamps 47, which are arranged in parallel along the first direction AA', which can enhance the clamping force and ensure the stability of drainage line operation. In an optional manner, the number of drainage line clamps can be adjusted as needed.

[0156] Two sixth driving mechanisms 48 are respectively provided corresponding to the two groups of drainage wire clamps 47, so that the two groups of drainage wire clamps 47 are driven to open and close successively by controlling the sixth driving mechanisms 48.

[0157] In one embodiment, the inner wall of at least one drain wire clamp 471 of the drain wire clamp 47 includes a first cross-sectional structure and a second cross-sectional structure, the first cross-sectional structure is closer to the bottom of the drain wire clamping space 47a (such as 8 not shown) than the second cross-sectional structure, and the first angle of the first cross-sectional structure is greater than the second angle of the second cross-sectional structure.

[0158] The second cross-sectional structure is close to the top entry port of the drainage wire clamping space 47a, and its second angle is smaller, which can squeeze the drainage wire into the drainage wire clamping space 47a, while the first cross-sectional structure located closer to the bottom has a relatively larger first angle, which can form a larger clamping surface for the drainage wire, exert a greater clamping force, and have a better clamping effect.

[0159] The present embodiment does not limit the values ​​of the first angle and the second angle, and they can be set as needed.

[0160] In the embodiments of the present disclosure, Figure 4 and Fig.12 As shown, to cooperate with the wire stripper 2 ( Fig.12 In the rotation and translation stripping stage (not shown), the wire stripper 2 is in its stripping space 2a ( Fig.12 A guide clamp 20 is installed on the inner side of the wire stripper 2, and the guide clamp 20 is configured to clamp the busbar during the wire stripping process of the wire stripper 2 and convert the rotational motion of the wire stripper 2 during the wire stripping process into a rotational motion along the busbar toward the second position w2 (synchronously with the wire stripper 2) Fig.12 (not shown) for linear motion.

[0161] During the rotation of the wire stripper 2, a friction pair is formed between the clamping surface of the guide clamp 20 and the busbar. Since the busbar is clamped, when the guide clamp 20 rotates synchronously with the wire stripper 2, the busbar generates friction resistance to the rotational movement of the guide clamp 20. Since the busbar is clamped and cannot move, the friction resistance applied by the busbar to the guide clamp 20 is converted into a translational driving force of the guide clamp 20, and the translational driving force is synchronously transmitted to the wire stripper 2. Therefore, part of the rotational movement of the wire stripper 2 is converted into the translational movement of the wire stripper 2.

[0162] In the cycle feed stage, the first drive mechanism 21 ( Fig.12 (not shown) outputs a dragging force to the wire stripper 2, which can prevent the translation tendency of the wire stripper 2 from being converted into an effective translation, so that the wire stripper 2 remains in place to rotate and strip the wire, or only translates forward a small amount;

[0163] During the rotational translation stripping stage, the guide clamp 20 will be converted into an effective translation of the wire stripper 2, and an effective driving force will be provided to the translation of the wire stripper 2 through the friction pair between the clamping surface and the busbar.

[0164] like Fig.12 As shown, the clamping surface 201 of the guide clamp 20 has a guide groove 22, which is used to convert the rotational motion of the wire stripper 2 into a translational motion. The guide groove 22 directly clamps the busbar, making it easier to convert the rotational motion of the wire stripper 2 during the stripping process into a translational motion with the first sliding member 2122 ( Figure 5 As shown) synchronously moves in a straight line along the busbar toward the second position w2.

[0165] In one embodiment, Fig.12 As shown, in each clamping jaw of the guide clamp 20, the guide pattern 22 includes two rows of inclined stripe structures 221, and each row of inclined stripe structures 221 includes a plurality of inclined stripe structures 221 arranged at intervals along the first direction AA'. The side of the inclined stripe structure 221 contacts the surface of the busbar, so that the friction resistance of the busbar to the guide clamp 20 is converted into the side of the inclined stripe structure 221 to move the wire stripper 2 to the second position w2 (as shown in FIG. Figure 4 ) translational motion.

[0166] In another embodiment, the guide pattern may spirally extend along the first direction toward the second position, which is not limited herein.

[0167] The disclosed embodiment also provides a method for controlling a fire connection operation based on any of the above embodiments, and the execution subject of the method for controlling a fire connection operation is a control system. Fig.13 As shown, the fire connection operation control method includes:

[0168] Step 1410: When the wire stripper is located at the first position and the busbar is located in the wire stripping space of the wire stripper and the wire clamping space of the busbar clamp, controlling the base busbar clamp to clamp the busbar;

[0169] Step 1420: Based on the current wire stripping starting position corresponding to the first position, the wire stripping operation is controlled to start, and the wire stripping operation includes a cyclic feed stage and a rotational translation stripping stage. In the cyclic feed stage, the first driving mechanism is controlled to output a dragging force to the wire stripper through the first translation output end, so that the wire stripper strips the wire in situ, and in the rotational translation stripping stage, the first driving mechanism is controlled to output a synchronous linear motion corresponding to the translation of the wire stripper through the first translation output end until the wire stripping end position, so as to obtain a busbar stripping segment corresponding to the position interval between the wire stripping starting position and the wire stripping end position;

[0170] Step 1430: after obtaining the busbar stripping section, controlling the first driving mechanism to drive the wire stripper to move along the first direction to the second position, and controlling the second driving mechanism to control the wire clamp connector carrying the wire clamp to be installed to move from the third position to the first position;

[0171] Step 1440: When the wire clamp connector is located at the first position, the wire clamp connector is controlled to install the wire clamp to be installed and the busbar stripping section.

[0172] In the fire connection operation control method using the fire connection operation equipment of this embodiment, the fire connection operation equipment itself does not move relative to the busbar, and the entire fire connection operation process is highly integrated in the accommodating space in the base, thereby being able to relatively reduce the fire connection operation time and improve the fire connection operation efficiency.

[0173] Combined with the above Figure 1-Figure 4 In the present embodiment, in the initial state, the wire stripper 2 is transferred to the first position w1, the first busbar clamp 51 and the second busbar clamp 52 are both opened, the busbar input wire enters the first wire clamping space 51a, the second wire clamping space 52a and the wire stripping space 2a of the wire stripper 2, and then the first busbar clamp 51 and the second busbar clamp 52 are controlled to clamp the busbar.

[0174] During the wire stripping operation of step 1420, the wire stripping operation is divided into a cyclic feed stage and an accelerated stripping stage (i.e., a rotational translational stripping stage); thus, the wire stripper 2 is controlled to perform the wire stripping operation based on the current wire stripping starting position corresponding to the first position w1, including:

[0175] In the cycle feed stage, based on the current wire stripping starting position corresponding to the first position w1, the wire stripper 2 is controlled to rotate and the wire stripping cutter of the wire stripper 2 is controlled to feed radially along the busbar to strip the outer sheath of the busbar until the wire core is exposed, and then the wire stripping cutter is controlled to stop feeding;

[0176] In the rotational translational stripping stage, after the wire stripping cutter is controlled to stop feeding, the wire stripper 2 is continuously controlled to rotate, and at the same time, the wire stripper 2 moves along the busbar toward the second position w2 to the wire stripping termination position.

[0177] In one embodiment, in combination Figure 4 and Fig.12 As shown, a guide clamp 20 is installed on the wire stripper 2;

[0178] After the base busbar clamp is controlled to clamp the busbar, before the wire stripper is controlled to perform the wire stripping operation based on the current wire stripping starting position corresponding to the first position, the fire connection operation control method further includes:

[0179] Control the guide clamp 20 to clamp the busbar;

[0180] The wire stripper 2 is continuously controlled to rotate, and the wire stripper 2 is simultaneously moved along the busbar toward the second position w2 to a wire stripping termination position, including:

[0181] The wire stripper 2 is continuously controlled to rotate, so that the guide clamp 20 converts the rotational motion of the wire stripper 2 into a synchronous translation of the wire stripper 2 toward the second position w2 to the wire stripping end position.

[0182] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
