Description

[0002] In today's electronic devices, wiring terminals are usually installed on circuit boards to achieve connections with external circuits. These terminals are used to fix and connect wires to transmit power or signals. However, due to the influence of the external environment, such as humidity, temperature changes, and erosion by pollutants, these exposed wires and terminals are prone to oxidation reactions, which in turn lead to corrosion. Oxidative corrosion not only damages the physical structure of the wire, but may also affect the stability of the electrical connection, increase resistance, and even cause open circuits or short circuits.

[0003] In order to prevent oxidation corrosion from affecting the stability of electrical connections, it is usually necessary to clean and maintain the wires and terminals regularly. This process involves disassembling the wires, removing the oxidized and corroded parts, and then reinstalling them; however, this process usually requires the equipment to be shut down to ensure the safety of operation. This method of shutdown cleaning is not only inefficient, but for critical equipment that needs to operate continuously, frequent shutdowns will cause production interruptions, affecting the normal operation time and overall efficiency of the equipment.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-10 An embodiment of the present invention discloses a terminal cleaning and fastening device for electrical components. Specifically, the cleaning and fastening device comprises a base frame 1 and a positioning fixture 3 installed on the base frame 1 for clamping the terminal 20 of the electrical component 2. It should be noted that the electrical component 2 targeted by the present invention is a terminal 20 external structure, so the terminal 20 can be clamped and positioned by the positioning fixture 3;

[0040] Reference Figure 2 , Figure 3, a screw driver 4, a cleaning unit 5 and a pulling unit 6 are also installed on the base frame 1, the screw driver 4 is used to tighten and loosen the fastener on the terminal 20, the pulling unit 6 is clamped on the outside of the wire 21 of the terminal 20, and pulls the wire 21 to move back and forth, and the cleaning unit 5 described in the present invention is used to spray an insulating cleaning liquid, so as to flush the wire core of the terminal 20 and the wire 21 to ensure the cleaning effect;

[0041] A conductive unit 7 is further provided between the positioning fixture 3 and the drawing unit 6 , and the conductive unit 7 is used to maintain continuous electrical conduction between the wire 21 and the terminal 20 .

[0042] That is, in the present invention, the fastener on the terminal 20 is loosened by the screw driver 4, and the wire 21 is driven by the pulling unit 6 to perform reciprocating friction motion with the terminal 20 to remove the oxide layer and corrosive substances on the terminal 20 and the wire 21 battery cell, and finally the cleaning unit 5 sprays cleaning liquid to flush the friction-dropped substances to ensure the comprehensiveness of the cleaning, thereby avoiding the problem of unstable conductivity caused by oxidation and corrosion at the connection between the terminal 20 and the wire 21. In addition, the present invention also adopts the design of the conductive unit 7, when cleaning the terminal 20 and the wire 21, the two can be kept in electrical connection at all times, so that online cleaning operations can be realized without power-off operation, which greatly improves the cleaning efficiency.

[0043] Reference Figure 1 In addition, the present invention also includes a shell 8 with a gripping portion 81. The shell 8 is a hollow structure. The base frame 1 is fixed to the inner side of the shell 8 to form an integral installation and fixing base. The shell 8 is provided with a plurality of avoidance openings 82, that is, the device described in the present invention as a whole adopts a handheld structure, so as to realize a convenient cleaning operation of the terminal 20 of the electrical component 2. Through the design of the gripping portion 81, a convenient gripping operation of the whole can be realized. Of course, the design of the avoidance opening 82 can be used to avoid the movement of the positioning fixture 3, the screw driver 4 and the pulling unit 6 to ensure that each unit can move and operate stably in the shell 8. A corresponding avoidance opening 82 can also be provided at the water tank 51 of the cleaning unit 5 to facilitate the refilling operation of the water tank 51.

[0044] Reference Figure 4 In some embodiments, the base frame 1 of the present invention includes a rod segment 11 and a first ring sleeve portion 12 and a second ring sleeve portion 13 formed at the front end of the rod segment 11;

[0045] Two connecting arms 14 are formed at the bottom of the rod section 11 , and guide rods 15 are fixedly mounted on both sides of the connecting arms 14 .

[0046] Reference Figure 5On the basis of the above embodiment, the screw driver 4 in this embodiment includes a screw motor 41 movably placed in the first ring sleeve portion 12, a fixing sleeve 42 is fixedly installed above the screw motor 41, a lifting motor 43 is also fixedly connected to the rod segment 11, and a screw rod 44 threadedly connected to the fixing sleeve 42 is fixedly connected to the shaft end of the lifting motor 43;

[0047] A tool sleeve 45 is fixedly mounted on the shaft end of the screw motor 41, a magnetic component 46 is fixedly mounted on the outer side of the tool sleeve 45, and a screwdriver 47 is plugged into the bottom of the tool sleeve 45. Specifically, the magnetic component 46 described in this embodiment is a permanent magnet, and the tool sleeve 45 is a magnetic conductive component such as an iron component. In this way, when the screwdriver 47 is plugged into the inside of the tool sleeve 45, it can be magnetically adsorbed by the magnetic force transmitted by the magnetic component 46. Of course, the tool sleeve 45 and the screwdriver 47 are circumferentially locked. The design purpose of adopting this structure is to facilitate the replacement of the screwdriver 47 to adapt to the disassembly and assembly requirements of different fasteners such as slotted screws or hexagon socket screws.

[0048] During specific operation, the lifting motor 43 drives the screw rod 44 to rotate to control the screw motor 41 to move up and down. The screw motor 41 drives the screwdriver 47 to be inserted into the top slot of the fastener and rotate. Thereafter, the fastener on the terminal 20 can be tightened or loosened by controlling the lifting and lowering of the screw motor 41. When the core of the wire 21 is loosened from the terminal 20, the wire 21 can be pulled back and forth by the pulling unit 6 to perform reciprocating plugging and pulling movements, so that friction cleaning of the terminal 20 and the core of the wire 21 can be achieved with the help of friction force.

[0049] Reference Figure 6 , Figure 7 Furthermore, the positioning fixture 3 of the present invention includes a clamping motor 31 fixed in the second ring sleeve portion 13, and the clamping motor 31 can be set as a reduction motor, which adopts a 90-degree reversing output design, and the two guide rods 15 on both sides of the connecting arm 14 are slidably connected with a clamping plate 32;

[0050] A first double-headed screw 33 is threadedly connected between the two clamping plates 32, and both ends of the first double-headed screw 33 are rotatably connected to the inner wall of the outer shell 8 to achieve lateral limiting. The shaft end of the clamping motor 31 and the middle part of the first double-headed screw 33 are fixedly installed with a first gear 34, and the two first gears 34 are meshed for transmission.

[0051] Reference Figure 7On the basis of the above embodiment, a threaded sleeve 35 is inserted on the end surface of the clamping plate 32, and the threaded sleeve 35 is circumferentially locked with the clamping plate 32. The specific circumferential locking method can be to open a guide groove along the axial direction on the outer side of the threaded sleeve 35, and set a protrusion in the hole of the clamping plate 32, so that the protrusion slides in the guide groove to achieve circumferential locking adaptation of the threaded sleeve 35, so as to ensure the first double-headed screw 33 to drive the threaded sleeve 35 smoothly;

[0052] The two sides of the threaded sleeve 35 have an outward expansion portion for stopping the side of the clamping plate 32, and a first spring 36 is fixedly connected between the outward expansion portion away from the clamping plate 32 and the clamping plate 32, and the first spring 36 is sleeved on the outside of the threaded sleeve 35;

[0053] The end of the first double-headed screw 33 is threadedly connected to the threaded sleeve 35 .

[0054] When working, the clamping motor 31 drives the first double-headed screw 33 to rotate. Since the two clamping plates 32 are threadedly connected to the two sides of the first double-headed screw 33, the two clamping plates 32 move synchronously toward each other on the guide rods 15 on both sides until they are clamped on both sides of the terminal 20 to complete the overall clamping positioning;

[0055] In addition, in the present invention, a floating threaded sleeve 35 is adopted on the clamping plate 32, and the clamping plate 32 is pushed to clamp the terminal 20 by the first spring 36 to ensure the contact stability between the clamping plate 32 and the terminal 20, thereby laying a good foundation for the subsequent connection and conduction of the conductive unit 7. As a further preference, a plurality of grooves are provided on the end surface of the clamping plate 32 in the embodiment of the present invention, which are used to increase the contact friction between the clamping plate 32 and the terminal 20 to further ensure the connection stability between the two.

[0056] Reference Figure 5 In some embodiments, the cleaning unit 5 of the present invention includes a water tank 51 fixed on the rod segment 11, and the top of the water tank 51 is detachably connected to a water tank cover, which is opposite to the avoidance opening 82 on the housing 8, so as to achieve a liquid replenishment operation on the water tank 51. Specifically, an insulating cleaning liquid is added to the water tank 51 of the present invention, and the side of the water tank 51 is connected to a liquid spraying pipe 53 through a water pump 52. Specifically, the liquid spraying pipe 53 described in this embodiment is a stainless steel pipe;

[0057] Reference Figure 5The end surface of the clamping plate 32 has an avoidance hole, and the spray pipe 53 is arranged between the two clamping plates 32 along the avoidance hole. That is, in the present invention, the cleaning liquid in the water tank 51 is pumped out by the water pump 52 and sprayed between the connection between the terminal 20 and the wire 21 by the spray pipe 53. In this way, when the wire 21 is pulled back and forth, the oxide layer and corrosive substances dropped by friction can be flushed to ensure comprehensive cleaning.

[0058] Furthermore, the shell 8 described in the present invention is located at the side of the water tank 51 and can be set as a transparent structure. At the same time, the water tank 51 is also set as a transparent water tank. The transparent structure design facilitates the observation of the liquid level inside the water tank 51, so that timely liquid replenishment operation can be achieved inside the water tank 51.

[0059] Reference Figure 8 , Fig. 9 In some embodiments, the pulling unit 6 in the present invention includes a slide 61 sliding on the rod segment 11, and two slide rods 62 are fixedly installed on both sides below the slide 61, and a clamping jaw 63 is slidably connected to the slide rod 62, and a second double-headed screw 64 is threadedly connected between the two clamping jaws 63. Of course, both ends of the second double-headed screw 64 described in the present invention are also rotatably connected to the inside of the shell 8 to achieve lateral limiting, and a clamping jaw motor 65 is fixedly installed on the slide 61. In this embodiment, the clamping jaw motor 65 is also configured as a reduction motor, which adopts a 90-degree change of direction output design, and a second gear 66 is fixed between the shaft end of the clamping jaw motor 65 and the middle part of the second double-headed screw 64, and the two second gears 66 are meshed for transmission.

[0060] It should be noted that, in the description of the present invention, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features, which are used to distinguish the described features, without any order or importance.

[0061] Reference Fig. 9 Preferably, the bottom of the clamp 63 described in the present invention has a clamping arm, and an opening adapted to the outside of the wire 21 is opened on the clamping arm, wherein the openings on the two clamps 63 are staggered with each other, so that when the two clamps 63 clamp the wire 21 relatively, the wire 21 can be clamped in an embracing manner, thereby improving the clamping stability of the wire 21.

[0062] It should be noted that the two clamps 63 in the present invention are clamped on the outside of the insulating outer skin of the conductor 21. When working, the second double-headed screw 64 is driven to rotate by the clamp motor 65. Similarly, since the two clamps 63 are threadedly connected to the two ends of the second double-headed screw 64, they will produce synchronous movement towards each other on the sliding rod 62 until the two clamps 63 are clamped on the outside of the insulating layer of the conductor 21.

[0063] Reference Fig. 9 Of course, in order to realize the movement and driving of the slide 61, a drawing motor 67 is also fixedly installed on the slide 61 in the present invention, and a rotating disk 68 is fixedly connected to the shaft end of the drawing motor 67, and a driving shaft 69 is eccentrically connected to the bottom of the rotating disk 68;

[0064] The side of the rod segment 11 is fixedly connected to a guide frame 16 , and the driving shaft 69 is movably connected to the inner side of the guide frame 16 .

[0065] Specifically, the side of the slide 61 in the present invention also has two ring sleeve positions, and the clamping motor 65 and the pulling motor 67 are respectively fixed in the two ring sleeve positions.

[0066] During operation, the pull-out motor 67 drives the turntable 68 to rotate continuously. Since a driving shaft 69 is eccentrically fixed to the bottom of the turntable 68, when the driving shaft 69 rotates inside the guide frame 16, the entire pull-out motor 67 is pushed to move. The pull-out motor 67 is fixed on the slide 61. At this time, the slide 61 drives the two clamping claws 63 to move back and forth, so that the wire 21 can be driven to perform a reciprocating plug-in and pull-out movement, so that friction is generated between the wire and the terminal 20;

[0067] It should be noted that during operation, the fasteners on the terminal 20 are first loosened by the screw driver 4. When loosening, the fasteners must maintain a certain pressing force on the end of the wire 21. In this way, during the reciprocating plugging and pulling of the wire 21, friction will be generated between the terminal 20 and the fastener, so as to remove the oxide layer and corrosive substances at the core of the terminal 20 and the wire 21.

[0068] Reference Fig.10 In a preferred embodiment, the conductive unit 7 in the present invention includes a mounting plate 71 fixed on the front side of the clamping jaw 63, and two mounting plates 71 are provided. A conductive clamping arm 73 is slidably connected to the end surface of the mounting plate 71 through at least two guide pillars 72, and the guide pillars 72 are fixedly mounted on the mounting plate 71. The end of the conductive clamping arm 73 described in this embodiment has an arc-shaped opening, and the arc-shaped opening design can achieve contact adaptation to the core of the wire 21. A second spring 74 is fixedly connected between the conductive clamping arm 73 and the mounting plate 71, and the two conductive clamping arms 73 are clamped on the outside of the core of the wire 21, and the conductive clamping arm 73 is electrically connected to the clamping plate 32 of the positioning fixture 3 through the wire 75. The two ends of the wire 75 described in this embodiment can be connected and fixed to the conductive clamping arm 73 and the clamping plate 32 by welding.

[0069] In the present invention, the conductive clamping arm 73 and the guide column 72 are movably plugged into each other to form a floating form, so that the wire cores of the wires 21 with different diameters can be adapted within a certain range. When the two clamping jaws 63 clamp and fix the insulating outer skin of the wire 21 during cleaning, the two conductive clamping arms 73 move synchronously with the clamping jaws 63 until the two conductive clamping arms 73 clamp the outer side of the wire core of the wire 21. At the same time, since the conductive clamping arm 73 is connected to the clamping plate 32 through the wire 75, and the clamping plate 32 is clamped on the outer side of the terminal 20, the wire core of the wire 21 and the terminal 20 can still be electrically connected during the subsequent reciprocating pulling of the wire 21. In this way, online cleaning can be achieved without stopping the machine, which greatly improves the cleaning efficiency.

[0070] In addition, it should be noted that the upper and lower parts of the clamp 32 in the present invention should be respectively set as an insulating part and a conductive part, the insulating part is slidably connected to the guide rod 15, and the conductive wire part is electrically connected to the wire 75, so that the voltage of the wire 75 is isolated to avoid interference with the internal electrical components, thereby ensuring the working safety of the device.

[0071] In summary, when cleaning the terminal 20 of the electrical component 2, first hold the device and clamp the positioning fixture 3 on both sides of the terminal 20 to achieve the overall positioning of the device, and then loosen the fastener on the terminal 20 by the screw driver 4. After loosening, the fastener needs to maintain a certain pressing force on the wire core of the wire 21 to facilitate subsequent friction cleaning;

[0072] After that, the pulling unit 6 is clamped and fixed on the outside of the wire 21, and drives the wire 21 to perform reciprocating insertion and extraction movements, and the friction between the terminal 20 and the wire core of the wire 21 is used to remove the oxide layer and corrosive substances at the connection between the two.

[0073] During the reciprocating drawing process, the cleaning unit 5 can be activated to spray the cleaning liquid on the drawing friction point between the two, so as to ensure the comprehensive flushing of the removed substances and greatly improve the cleaning effect;

[0074] After the cleaning is completed, the wire 21 is reset, the fastener is locked and reset using the screwdriver 4, and the positioning fixture 3 and the pulling unit 6 are released to complete the cleaning operation of the single terminal 20.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
