[0047] The embodiment of the present invention provides an insertion device and a wiring system for terminal wiring, which are used to solve the problem in the prior art that the same insertion device cannot adapt to wiring terminal holes with different apertures.

[0048] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figures 1 to 7 The present invention provides an insertion device for terminal wiring, which is used to insert into a wiring terminal hole 4, comprising:

[0050] Wiring pin 1, used for electrical connection with the equipment wiring terminal;

[0051] At least two insertion clamp arms 2 opened and closed relative to the terminal ejector pin 1, the two insertion clamp arms 2 are rotatably connected to the terminal ejector pin 1 via the same rotating shaft 24, and the terminal ejector pin 1 is arranged in the opening formed by the two insertion clamp arms 2;

[0052] The telescopic spring assembly 3 is located in the opening and closing opening formed by the two insertion clamping arms 2. The telescopic spring assembly 3 is compressed between the two insertion clamping arms 2. The telescopic spring assembly 3 is connected to both insertion clamping arms 2. The telescopic spring assembly 3 is used to keep the two insertion clamping arms 2 moving away from each other, so as to drive the opening and closing opening provided with the wiring ejector pin 1 to maintain an opening trend.

[0053] It should be pointed out that the insertion device is inserted into the terminal hole 4, that is, the terminal pin 1 and the insertion clamp arm 2 are both inserted into the terminal hole 4, that is, the outer diameter of the insertion end of the two closed insertion clamp arms 2 is less than or equal to the inner diameter of the terminal hole 4 to ensure that the insertion device can be inserted into the terminal hole 4.

[0054] During the application of this embodiment, the user clamps the two insertion clamp arms 2 so that they are retracted and closed toward the adjacent wiring pin 1. At the same time, the telescopic spring assembly 3 is compressed, and then the retracted and closed insertion clamp arms 2 are inserted into the device wiring terminal hole 4; when the wiring pin 1 is electrically connected to the device wiring terminal, the user releases the two insertion clamp arms 2, and the elastic force of the telescopic spring assembly 3 expands the two insertion clamp arms 2 away from the wiring pin 1. The expanded insertion clamp arms 2 will abut against the inner wall of the terminal hole 4, and the wiring pin 1 will be firmly installed in the device wiring terminal hole 4.

[0055] From the above process, it can be seen that the two inserted clamp arms 2 that are folded and combined will be inserted into the terminal hole 4 together with the wiring pin 1. When the wiring pin 1 is electrically connected to the terminal, the two inserted clamp arms 2 are released, and the spring will press the two inserted clamp arms 2 against the inner wall of the terminal hole 4. Regardless of whether the terminal hole 4 is too large or too small, the inserted clamp arms 2 can abut against the inner wall of the terminal hole 4 and firmly install the wiring pin 1 in the equipment wiring terminal hole 4.

[0056] Compared with the prior art, the present embodiment has the following advantages: first, the wiring ejector pin 1 is fastened and installed in the wiring terminal holes 4 of different devices and different aperture sizes. Compared with the prior art, there is no need to use multiple insertion devices to install the ejector pins. Only one insertion device for terminal wiring can achieve fastening and installation of terminals with different aperture sizes, which facilitates production work; second, the fixing process of the wiring ejector pin 1 will not affect the wiring of other terminals. In the prior art, a clip is usually used to clamp the side of the wire row or the outer wall of the end hole. This device is large in size and will block the connection and installation of other terminal holes 4. The present embodiment uses the friction between the insertion clamp arm 2 and the inner wall of the wiring terminal hole 4 to fix the wiring ejector pin 1 to avoid affecting the wiring of other terminals. In addition, the present device is small in size and can be used normally for adjacent terminals.

[0057] In a specific embodiment, if Figures 1 to 3 As shown, a feasible structure of the insertion clamp arm 2 is further provided, the insertion clamp arm 2 includes an insertion portion 20 for inserting into the terminal hole 4 and a free portion 21 for being clamped; the insertion portion 20 and the free portion 21 are arranged at opposite ends of the insertion clamp arm 2; a first opening and closing opening 200 that can be opened and closed is formed between the insertion portions 20 of the two insertion clamp arms 2, and the pointed needle end of the terminal pin 1 is arranged adjacent to the first opening and closing opening 200; a second opening and closing opening 210 that can be opened and closed is formed between the free portions 21 of the two insertion clamp arms 2, and the telescopic spring assembly 3 is arranged in the second opening and closing opening 210, and the two free portions 21 are close to or away from each other to control the opening and closing of the first opening and closing opening 200 and the second opening and closing opening 210. In specific implementation, the user or a robot clamp can clamp the two free portions 21. When the two free parts 21 are clamped, the two free parts 21 approach each other to control the first opening and closing mouth 200 and the second opening and closing mouth 210 to close. At this time, at the first opening and closing mouth 200, part of the column of the terminal pin 1 will be wrapped by the two insertion parts 20, and at the second opening and closing mouth 210, the telescopic spring assembly 3 is clamped and compressed by the two insertion parts 20; when the two free parts 21 are relaxed, the two free parts 21 move away from each other to control the first opening and closing mouth 200 and the second opening and closing mouth 210 to open. At this time, at the second opening and closing mouth 210, the telescopic spring assembly 3 will extend, driving the two free parts 21 to expand, and at the first opening and closing mouth 200, the two insertion parts 20 will abut against the inner wall of the terminal hole 4 after expansion, thereby fixing the terminal pin 1 in the terminal hole 4.

[0058] In one embodiment, if Figure 6 As shown, in order to prevent the insertion part 20 or the terminal pin 1 from slipping out of the terminal hole 4, when the first opening and closing mouth 200 is closed, the two insertion parts 20 form a columnar body, and the outer diameter of the columnar body is less than or equal to the terminal hole 4 of the insertion device. In specific implementation, after clamping the two free parts 21, that is, when the first opening and closing mouth 200 is closed, the columnar body can ensure that the insertion part 20 and the terminal pin 1 are inserted into the terminal hole 4 with a sufficient depth, thereby avoiding the problem that the insertion part 20 is not inserted deeply enough, resulting in the terminal pin 1 being unable to achieve electrical connection, or the insertion part 20 cannot be pressed against the inner wall of the hole and thus slips out.

[0059] In this embodiment, the outer diameter of the formed columnar body is 3-4 mm, that is, the distance from the outer wall of the insertion part 20 to the inner wall of the insertion part 20 is 1.5-2 mm. In specific implementation, the two closed insertion parts 20 can be smoothly inserted into the terminal hole 4 of the existing substation with a diameter of 4mm-6mm or even larger.

[0060] It should be noted that the shape of the columnar body can be a cylinder or a regular variable prism, such as a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, etc., and those skilled in the art can choose according to actual needs.

[0061] In one embodiment, if Figure 3 As shown, in order to make the arrangement structure of the insertion portion 20 and the terminal ejector pin 1 more compact, the inner wall of the insertion portion 20 is provided with a receiving groove 201, and the slotted axis direction of the receiving groove 201 is the same as the direction of the line connecting the two ends of the insertion clamping arm 2. When the inner wall surfaces of the two insertion clamping arms 2 are fitted together, the cavity enclosed by the adjacent receiving grooves 201 matches the shape of the terminal ejector pin 1, that is, the receiving groove 201 is a semi-cylindrical structure. In specific implementation, when the insertion portions 20 of the two insertion clamping arms 2 are fitted together, the terminal ejector pin 1 will be located as a whole in the cavity enclosed by the two receiving grooves 201, and the terminal ejector pin 1 will abut against the inner wall of the receiving groove 201. After the two insertion clamping arms 2 are fitted together, the entire structure is more compact and can be suitable for terminal holes 4 with different apertures.

[0062] In this embodiment, the anti-slip portion 202 is a plurality of anti-slip spikes, which are arranged in a circular array on the outer wall of the insertion portion 20. When the anti-slip portion 202 of the insertion portion 20 is pressed against the inner wall of the terminal hole 4, the anti-slip spikes can increase the friction with the inner wall of the terminal hole 4 to prevent the insertion portion 20 from sliding, thereby ensuring that the terminal pin 1 is firmly installed. Of course, in addition to the anti-slip spikes, the anti-slip portion 202 can also be an anti-slip layer formed of anti-slip rubber or anti-slip plastic.

[0063] In one embodiment, if Figures 1 to 3As shown, in order to improve the accuracy of clamping, the free portion 21 includes an arc-shaped guiding protrusion 211 and two centering plates 212; the long axis direction of the arc-shaped guiding protrusion 211 is the same as the direction of the line connecting the two ends of the inserted clamping arm 2; the two centering plates 212 are arranged on the opposite sides of the arc-shaped guiding protrusion 211, and the centering plates 212 are fixedly connected to the arc-shaped guiding protrusion 211, and the inner side surface of the centering plate 212 is flush with the inner side surface of the arc-shaped guiding protrusion 211. In specific implementation, when a robot clamp or an ordinary clamp clamps the free portion 21 of the inserted clamping arm 2, if the robot clamp clamps incorrectly or slightly deviates, the arc-shaped guiding protrusion 211 of a specific shape will be in the clamp. Fine-tuning: the horizontal force component of the arc-shaped guiding protrusion 211 can offset each other or be limited within a certain range, while the vertical force component will prompt the clamping arm to move in the vertical direction, thereby realizing vertical guidance of the clamping arm; and in the case of a deflection in the clamping angle of the robot clamp, the plane of the centering plate 212 is used as the reference plane. When the free portion 21 of the inserted clamping arm 2 is deflected to the reference plane, it can ensure that the inserted clamping arm 2 has the correct deflection angle after being clamped, that is, when the clamping alignment of the robot clamp is incorrect or slightly deviated, the correct vertical position can be achieved through the tail arc-shaped guiding protrusion 211, and the correct deflection angle can be achieved through the centering plate 212, thereby realizing automatic matching and centering.

[0064] In this embodiment, if Figure 3 As shown, the arc-shaped guiding protrusion 211 includes two quarter spheres 2110 and a semi-arc cylinder 2111; the two ends of the semi-arc cylinder 2111 are respectively fixedly connected with the quarter sphere 2110, and the surface of the quarter sphere 2110 and the surface of the semi-arc cylinder 2111 are smoothly transitioned. In specific implementation, the quarter spheres 2110 and the semi-arc cylinder 2111 at both ends form a structure with arc surfaces on the circumference, which can guide in all directions; and in the process of inserting the clamping arm 2 close to the workpiece, when transitioning from the spherical part to the semi-arc cylinder 2111 part, no jamming or offset will occur due to the sudden change of the structure, so that the guiding force can act on the clamping arm continuously and evenly, ensuring that the clamping arm approaches the workpiece smoothly along a predetermined trajectory, which is conducive to achieving precise clamping operation.

[0065] In one embodiment, if Figure 2 As shown, the inner wall of the free portion 21 is also provided with a receiving groove 213. After the two free portions 21 are fitted together, the cavity enclosed by the two receiving grooves 213 can match the shape of the terminal pin 1. A spring mounting hole for spring installation is also provided in the receiving groove 213. The first spring 30 or the second spring 31 is installed on the insertion clamp arm 2 through the spring mounting hole.

[0066] In a specific embodiment, Figures 1 to 3As shown, a possible matching mode of two insertion clamp arms 2 is further provided, wherein one insertion clamp arm 2 is a first insertion clamp arm 22, and the other insertion clamp arm 2 is a second insertion clamp arm 23; the first insertion clamp arm 22 is provided with a first inclined through hole 220 and a first horizontal through hole 221; the second insertion clamp arm 23 is provided with a second inclined through hole 230 and a second horizontal through hole 231; the wiring ejector pin 1 is provided with a third horizontal through hole 10; the first insertion clamp arm 22 is inserted into the second insertion clamp arm 23 through the second inclined through hole 230 to form an "X"-shaped insertion structure; the wiring ejector pin 1 is inserted into the first inclined through hole 220 and the second inclined through hole 231 Insert the first insertion clamp arm 22 and the second insertion clamp arm 23; a rotating shaft 24 is provided in the first horizontal through hole 221, the second horizontal through hole 231 and the third horizontal through hole 10, and both ends of the rotating shaft 24 extend out of the insertion clamp arm 2, and both ends of the rotating shaft 24 are connected with a limit member 25 for limiting the movement of the rotating shaft 24, and the limit member 25 is a nut for fixing the two ends of the rotating shaft 24. In specific implementation, the two insertion clamp arms 2 can rotate around the rotating shaft 24 on the wiring ejector pin 1 to open and close. The interlaced insertion clamp arm 2 structure can, on the one hand, make the structure of the two insertion clamp arms 2 and the wiring ejector pin 1 more compact, and on the other hand, the interlaced structure has a higher structural strength.

[0067] It should be pointed out that the first insertion clamp arm 22 and the second insertion clamp arm 23 both include an upper arm body and a lower arm body, both of which are semi-cylinders, and the end of the upper arm body is provided with a first concave through groove to form a concave end structure, and the end of the lower arm body is provided with a second concave through groove to form a concave end structure, and one end of the upper arm body provided with the first concave through groove is arranged adjacent to the lower arm body, and one end of the lower arm body provided with the second concave through groove is arranged adjacent to the upper arm body, and the first concave through groove and the second concave through groove are connected to form an inclined through hole, that is, the structures of the first insertion clamp arm 22 and the second insertion clamp arm 23 are basically the same, except that the hole size of the first inclined through hole 220 is larger than the arm diameter size of the second insertion clamp arm 23, so as to realize the interlaced matching structure of the first insertion clamp arm 22 and the second insertion clamp arm 23.

[0068] In a specific embodiment, Figure 1 As shown, a feasible structure of the telescopic spring assembly 3 is further provided, and the telescopic spring assembly 3 includes a first spring 30 and a second spring 31; the first spring 30 is compressed between the terminal pin 1 and the insertion clamp arm 2, and the second spring 31 is compressed between the terminal pin 1 and the other insertion clamp arm 2, and the first spring 30 and the second spring 31 are coaxially arranged. In specific implementation, when the two insertion clamp arms 2 are clamped, the first spring 30 and the second spring 31 are both compressed, and the arrangement of the two springs can make the clamping force more flexible. For example, when one insertion clamp arm 2 is damaged, it is necessary to replace the elastic coefficient of a certain spring so that the two insertion clamp arms 2 can be clamped better.

[0069] It should be noted that in some possible embodiments, the telescopic spring assembly 3 is composed of a complete single spring, and the single spring is compressed between the two insertion clamp arms 2; in specific implementation, the single spring can also achieve the tendency of the two insertion clamp arms 2 to maintain a movement away from each other.

[0070] In a specific embodiment, Figure 4 As shown, an achievable structure of the terminal thimble 1 is further provided. The terminal thimble 1 is a retractable thimble. In specific implementation, when the terminal thimble 1 is inserted and abuts against the bottom of the terminal hole 4, the terminal thimble 1 will retract to prevent wear and damage caused by excessive extrusion.

[0071] In one embodiment, the terminal pin 1 includes a terminal rod, a telescopic rod, a telescopic spring and a connecting needle body. One end of the terminal rod is connected and fixed to one end of the telescopic rod, and the other end of the telescopic rod is fixed to a plurality of connecting needle bodies. The interior of the telescopic rod is hollow, and the telescopic spring is arranged in the hollow interior of the telescopic rod. During specific implementation, after the connecting needle body touches the bottom, the terminal rod continues to move downward to squeeze the telescopic spring, and the contracted telescopic spring can maintain appropriate pressure on the connecting needle body.

[0072] This embodiment provides a wiring system, including:

[0073] Insertion device for terminal wiring;

[0074] An image recognition device, the image recognition device is used to recognize the terminal hole 4 to be inserted;

[0075] A robot, the robot comprising a three-axis moving part and a clamping part arranged on the three-axis moving part, the clamping part being used to clamp or release an insertion device for terminal wiring;

[0076] The control device is connected with the image recognition device and the robot signal. The control device is used to receive the signal of the image recognition device, and output instructions to the three-axis moving part to move the clamping part into or out of the terminal hole 4, and output instructions to the insertion device for clamping or releasing the terminal wiring by the clamping part.

[0077] During the terminal wiring process of the present embodiment, the clamping component of the robot clamps the insertion device for terminal wiring so that the two insertion clamp arms 2 are closed; the image recognition device identifies the position of the terminal hole 4 to be installed, and the image recognition device transmits the identified information to the control device. The control device analyzes the movement trajectory and outputs a movement command to the three-axis moving component to move the insertion device for terminal wiring into the terminal hole 4. After the terminal hole 4 is inserted, the clamping component of the robot releases the insertion device for terminal wiring, and the two insertion clamp arms 2 open and abut against the inner wall of the terminal hole 4 to achieve automatic tightening in the terminal hole 4. At this time, the robot can perform wiring of other wiring holes. Of course, the step of moving the insertion device for terminal wiring out of the terminal hole 4 is opposite to the above process and will not be elaborated here.

[0078] From the above process, it can be seen that the robot can combine image recognition technology and insertion device technology for terminal wiring. After the robot recognizes the position of the terminal hole 4, the insertion device for terminal wiring can be automatically clamped in the terminal hole 4 to realize automatic wiring after the robot is based on vision positioning.

[0079] Compared with the prior art, the present invention has the following advantages: first, the terminal wiring can be installed automatically, thus avoiding the situation that the prior art requires only repeated manual installation; second, the terminal wiring is convenient and accurate. In the prior art, when the robot is operated, in addition to judging the position of the terminal hole 4, it is also necessary to judge whether there is a clamping position outside. Among them, judging whether there is a clamping position outside is relatively difficult, while in the present scheme, it is only necessary to image recognize the terminal hole 4, and then insert and release the insertion device for terminal wiring to achieve terminal fastening and wiring; third, it can realize accurate centering and offset positioning of the robot fixture. The free part 21 of the insertion device for terminal wiring is optimized for robot clamping, which can ensure normal clamping when there is an angle or position deviation in the fixture position.

[0080] In a specific embodiment, an implementable structure of an image recognition device is further provided. The image recognition device includes an image acquisition unit, a light source unit, an image processing unit and a communication unit. The image of the terminal hole 4 is acquired through the cooperation of the image acquisition unit and the light source unit. The image of the terminal hole 4 is then transmitted to the image processing unit for positioning analysis to determine whether it is the terminal hole 4. Finally, the result is transmitted to the control device to complete the image recognition and positioning of the terminal hole 4. It should be pointed out that the image recognition device is a common technology and will not be elaborated on here.
