Description

Technical Field

[0001] The present invention relates to the field of smart socket strips, and in particular to an assembly device for a charging socket strip. Background Art

[0002] The main causes of electrical fires are leakage, short circuit, overload, poor contact and other faults. Among them, electrical fires caused by leakage, short circuit and overload caused by external devices when single-phase power strips are working are more common.

[0003] In daily life, power strips are sometimes used in humid environments, such as being placed on water-stained floors. When used in these environments, people usually only subjectively avoid water seeping in from the sockets, but often ignore the bottom and surrounding gaps of the power strip. These locations are more likely to be exposed to water, causing water to penetrate through the screw holes and surrounding gaps, affecting the safety of normal use and the life of the product. Therefore, it is necessary to focus on waterproofing and sealing these locations of the power strip.

[0004] Patent document WO2017118240A1 discloses a waterproof socket comprising a socket body with a jack provided with waterproof rubber. The waterproof rubber has a gap in the middle to facilitate insertion of the electrodes of an electrical plug. The socket has the waterproof rubber provided on the jack. Due to the elasticity of the rubber, once an electrical plug is inserted into the waterproof rubber, the rubber adheres to the plug, blocking water intrusion and preventing water droplets from splashing into the socket.

[0005] However, in actual use, the power strip may be used in a humid environment, causing water to seep in through the gaps and screw holes around it, affecting product safety and shortening its lifespan. Summary of the Invention

[0041] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, an assembly device for a charging power strip includes:

[0043] An assembly mechanism 1 for assembling a variety of materials, comprising a plurality of placement members 11 for placing the materials into the power strip box and a moving member 12 for transporting the box;

[0044] A positioning mechanism 2 is provided behind the assembly mechanism 1 and is used to fix the position of the wiring box. The positioning mechanism 2 includes a stabilizing member 21 for maintaining the position of the wiring box and a vibrating member 22 provided behind the stabilizing member 21 for vibrating the wiring box.

[0045] The gluing mechanism 3 is arranged above the positioning mechanism 2 and includes a gluing machine 31 and a coating assembly 32 arranged below the gluing machine 31;

[0046] The fixing mechanism 4 is arranged behind the gluing mechanism 3 and is used to fix the wire box and the base plate, including an automatic screwing machine 41, a fastening component 42 for accurately fastening the wire box and the base plate, and a sealing component 43 for sealing the screw holes of the base plate.

[0047] In this embodiment, by providing a gluing mechanism 3 and a fixing mechanism 4, waterproof glue is applied to the edge of the wire box and the screw holes during the assembly of the power strip, so that the waterproof glue can seal the screw holes of the wire board and the gaps around it, thereby improving the waterproof performance of the power strip.

[0048] In detail, the various parts of the power strip are arranged and placed in the junction box through the combination mechanism 1, and then the junction box is positioned by the positioning mechanism 2, so that the edge of the junction box is coated with glue by the gluing mechanism 3 to ensure uniform and complete gluing. Finally, the junction box and the base plate are assembled through the fixing mechanism 4, and the screw holes are finally sealed to complete the production.

[0049] It should be noted that there are installation grooves around the junction box, and there are many wedge-shaped blocks on the installation grooves, which cooperate with the protrusions and wedge-shaped blocks on the bottom plate for preliminary fixation, and then use screws to complete the overall fixation. By adding waterproof glue to the installation grooves and screw holes, the bottom plate and the junction box are sealed, thereby preventing water stains from seeping in through the gaps and screw holes.

[0050] Further, if Figure 2 As shown, each group of the placement members 11 includes a vibration plate 111 for conveying materials and a clamping robot 112 provided at the output end of the vibration plate 111;

[0051] The moving part 12 includes a guide rail 121 for moving the wire box and a push plate 122 arranged on the guide rail 121, multiple groups of pressure blocks 123 are vertically slidably connected to the push plate 122, a spring is arranged between the lower part of the pressure block 123 and the push plate 122, and the pressure block 123 is provided with a contact switch corresponding to the surface of the push plate 122, wherein the push plate 122 is moved up and down and forward and backward by a telescopic cylinder.

[0052] In this embodiment, a plurality of holding robots are provided to arrange the various parts inside the power strip in an orderly manner, and then the wire box is inspected and moved by the moving part 12 .

[0053] In detail, when all the parts are placed, the push plate 122 moves downward so that the lower surface of the pressure block 123 contacts the parts in the wiring box. Under the action of the spring, the vertical position of the pressure block 123 changes. If all the parts are placed well, the contact switch of the pressure block 123 is connected, that is, the parts are placed. At this time, the push block 426 moves horizontally backward, pushing the wiring box a distance for subsequent operations, and then the push plate 122 moves up and returns to its position.

[0054] It should be noted that if there is a problem of tilting or misplacement of the parts during placement, the position of the pressure block 123 above the parts will be different from the position of the contact switch, thereby detecting and identifying the problem of poor placement to ensure assembly quality.

[0055] Further, if Figure 3 、 Figure 4 As shown, the stabilizing member 21 includes four groups of cards 211 arranged on the guide rail 121, a stabilizing block 212 that controls the movement of the cards 211 through an electric cylinder, and a first slide rail 213 that drives the stabilizing block 212 to move up and down and horizontally through an electric cylinder.

[0056] Further, if Figure 3 As shown, the stabilizing member 21 also includes a hanging rail 214 arranged on the outside of each group of cards 211 and fixedly connected to the stabilizing block 212, a protrusion 215 slidably connected to the hanging rail 214 and capable of being sunk into the mounting groove of the wire box, a dial 218 rotatably connected to the four sides of the protrusion 215, a grinding knife 216 arranged behind the protrusion 215 and slidably connected to the hanging rail 214, and a vacuum cleaner 217 arranged above the grinding knife 216.

[0057] In order to allow the protrusion 215 and the grinding knife 216 to slide on the hanging rail 214, a slider is slidably connected to the hanging rail 214, and the protrusion 215 and the grinding knife 216 are set below the slider. A motor-driven gear is set at the upper end of the slider, and a rack is set on the hanging rail 214 to make the gear engage with the rack, so that the rotation of the gear drives the slider to move in a straight line on the hanging rail 214. When the slider moves to the corner, the gear disengages from the rack on this side, and an electric cylinder is set at the corner of the hanging rail 214. The electric cylinder pushes the slider out of the corner and pushes it to the other side, and makes the gear contact with the rack, and the slider continues to move along the edge.

[0058] The protrusion 215 is square, and the four sides are connected to the rotary dials 218. A motor is set above the protrusion 215, and the four dials 218 can be driven to rotate at the same time by using bevel gears. When the protrusion 215 moves in the wire box mounting groove, the dials 218 on both sides contact the side walls of the mounting groove, scraping the burrs on the side walls out of the mounting groove. When the protrusion 215 turns, the other two sides contact the side walls of the mounting groove. The protrusion 215 cooperates with the movement of the slider to hang the burrs out of the mounting groove, making it easier for the grinding knife 216 to clean it.

[0059] In this embodiment, by setting a card 211 and a stabilizing block 212, when the push plate 122 pushes the wire box to the bottom of the stabilizing member 21, the stabilizing block 212 moves downward, allowing the card 211 to penetrate into the interior of the wire box, and then the cards 211 are driven by the electric cylinder to move away from each other. After the card 211 contacts the inner surface of the wire box, the wire box is fixed and positioned to prevent the position of the wire box from deviating. The hanging rail 214 moves downward following the stabilizing block 212, and the protrusion 215 enters the installation groove of the wire box. At the same time, the grinding knife 216 is attached to the surface of the wire box. The protrusion 215, the grinding knife 216 and the vacuum cleaner 217 move along the hanging rail 214. The protrusion 215 moves to push the burrs in the installation groove out of the installation groove, the grinding knife 216 removes the burrs, and the vacuum cleaner 217 sucks out the debris to remove the burrs.

[0060] In detail, when the surface of the wire box is processed using the grinding knife 216, on the one hand, the burrs are removed to prevent the burrs from affecting the subsequent coating of waterproof glue or the fit between the wire box and the base plate. On the other hand, the grinding knife 216 is rotated to make the surface of the wire box present a certain degree of roughness under the operation of the grinding knife 216. An appropriately rough surface can be conducive to the bonding of the waterproof glue and improve the sealing degree.

[0061] Further, if Figure 5 、 Figure 6 As shown, the vibrating member 22 is provided in two groups and is respectively located on both sides of the guide rail 121, including a fixing block 221 for fixing the edge of the wire box, a cam 222 provided on the fixing block 221 and driven by a motor, and a contact block 223 provided on the fixing block 221 close to one side of the wire box.

[0062] In this embodiment, by setting a fixed block 221 and a cam 222, the vibration of the wire box is achieved, and the vibration of the wire box is used to assist in the addition of waterproof glue, thereby avoiding bubbles in the waterproof glue in the installation groove, resulting in uneven coating of the waterproof glue.

[0063] The fixed block 221 is controlled to move up and down by a cylinder fixed on the frame. The contact block 223 is set on the inner side of the fixed block 221 and the lower part is wedge-shaped. The contact block 223 should be set to an elastic material such as rubber. When the fixed block 221 descends, the contact block 223 contacts the surface of the wire box, forming a lateral extrusion on the wire box, thereby completing the fixation and limitation of the wire box.

[0064] In detail, after the burrs are removed from the stabilizer 21, the wire box is moved again and moved to the bottom of the vibrator 22. The fixed block 221 moves down to fix the four sides of the wire box. Then the stabilizer 212 moves up, the stabilizer 21 is separated from the wire box and returned to its position. The fixed block 221 is engaged to complete the fixation of the wire box. The cam 222 rotates and the cam 222 continuously hits the surface of the wire box. Since the contact block 223 is made of elastic material, the wire box is vibrated. The vibration of the wire box cooperates with the waterproof glue coating work of the subsequent coating component 32.

[0065] Further, if Figure 7 、 Figure 8 、 Figure 9 As shown, the coating assembly 32 includes a control block 321 arranged above the vibrating member 22, multiple groups of glue injection tubes 322 arranged on the control block 321 and sliding horizontally, a liquid storage piston 323 arranged on the control block 321 and connected to the glue injection tubes 322, and a coating roller 324 arranged at the bottom of the glue injection tube 322 and sliding up and down on the glue injection tube 322 through an electric cylinder. A liquid outlet is provided at the bottom of the glue injection tube 322.

[0066] In this embodiment, the waterproof glue is applied to the installation groove by providing a glue injection tube 322 and a coating roller 324 , so that the waterproof glue can be evenly applied to the installation groove.

[0067] In detail, after the vibrating member 22 fixes the wire box, the control block 321 is lowered by the cylinder control, so that the glue injection tube 322 and the coating roller 324 extend into the installation groove, and the glue injection tube 322 is controlled to move by the electric cylinder, wherein 8 groups of glue injection tubes 322 are provided, and two groups of glue injection tubes 322 are provided on the side of each installation groove. The glue injection tube 322 is pushed to both ends by the electric cylinder located in the middle position of each side, and the coating is completed during the movement. The glue coating machine 31 adds waterproof glue to each group of liquid storage pistons 323, and controls the waterproof glue to be released from the glue injection tube 322 by the liquid storage piston 323. At this time, the coating roller 324 is located at the liquid outlet at the lower end of the glue injection tube 322, and the waterproof glue wets the coating roller 324, and the side wall of the installation groove is coated with a layer of waterproof glue by the coating roller 324. After the installation groove is completely coated, the coating roller 324 moves up, the liquid outlet is opened, and the waterproof glue is directly transported to the installation groove through the liquid outlet to complete the filling of the waterproof glue.

[0068] The surface of the coating roller 324 should be made of a soft and easy-to-coat material such as felt. On the one hand, this material facilitates uniform coating. On the other hand, it facilitates positioning when the glue injection tube 322 descends, so that the coating roller 324 can enter the installation groove. Avoid using hard materials to prevent the coating roller 324 from colliding with the edge of the wire box due to the production tolerance of the wire box when the glue injection tube 322 descends, and the coating roller 324 cannot enter the wire box installation groove.

[0069] It should be noted that the installation groove is first coated by the coating roller 324, and then the waterproof glue is released, that is, the surface is first coated when the glue injection tube 322 moves to both ends, and glue is injected when it returns to its position. Since the waterproof glue has a certain viscosity, directly releasing the waterproof glue may cause bubbles to remain at the corners of the installation groove. By first applying a layer of waterproof glue and then filling the waterproof glue, it can effectively avoid the waterproof glue from adhering to the side wall of the installation groove, causing a large number of bubbles to remain. After the glue is applied, the vibrator 22 vibrates. On the one hand, the small bubbles can be quickly eliminated by vibration. On the other hand, the amount of waterproof glue at each position in the installation groove can be kept balanced by vibration, and the release is more uniform.

[0070] It is worth mentioning that a layer of waterproof glue is applied on the waterproof glue by the coating roller 324, leaving a water mark on the side wall of the installation groove. The position of the water mark is higher than the liquid level of the waterproof glue filled subsequently. The water mark left can control the flow direction of the waterproof glue when the subsequent base plate is buckled, so that the waterproof glue can flow to the side with higher water marks. Therefore, when the side wall of the installation groove is coated with the coating roller 324, the position of the coating roller 324 is adjusted to make the water mark on the outer wall higher than the water mark on the inner wall, so that when the base plate is installed, the waterproof glue overflows. Due to friction, the waterproof glue flows more to the outside, which prevents the waterproof glue from flowing into the inside of the wire box and contaminating components on the one hand, and makes the waterproof glue flow to the outside. When the wire box fails during use, it is convenient to use a blade or the like to cut the waterproof glue, thereby realizing the disassembly of the wire box.

[0071] Further, if Figure 10 、 Figure 11 As shown, the fastening assembly 42 includes a bottom plate conveying rail 421 provided on the other side of the automatic screw driving machine 41, a clamping block 422 provided at the end of the conveying rail 421 and moved to both sides by an electric cylinder, a pressing plate 423 provided above the clamping block 422 and moved downward by an electric cylinder, and a plurality of extrusion plates 424 rotatably connected to the edges of the pressing plate 423. The extrusion plates 424 are driven to rotate by an electric cylinder hinged on the upper surface of the pressing plate 423.

[0072] In this embodiment, the base plate is fixed and clamped by setting a clamping block 422 and an extrusion plate 424. The base plate conveying rail 421 conveys the base plate to the bottom of the automatic screw tightening machine 41. The clamping block 422 moves the base plate from the conveying rail 421. The pressure plate 423 presses down to contact the surface of the base plate. The extrusion plates 424 around it rotate to clamp the side walls of the base plate. The extrusion plates 424 cause the side walls of the base plate to undergo a slight bending deformation. Then the pressure plate 423 continues to move downward, and the base plate is buckled into the wire box moved to the bottom to tighten the screws.

[0073] In detail, since wedge-shaped blocks are provided on both the bottom plate and the wire box, if the bottom plate is directly fastened to the wire box, the wedge-shaped blocks will collide, which may cause splashing of the waterproof glue, and the waterproof glue cannot form a complete bonding surface when it overflows, thereby weakening the sealing effect. The side wall of the bottom plate is squeezed by the extrusion plate 424 to avoid collision between the wire box and the wedge-shaped blocks on the bottom plate. After fastening, the extrusion plate 424 is slowly loosened to prevent uncontrolled splashing of the waterproof glue.

[0074] It should be noted that the use of the extrusion plate 424 to completely deform the bottom plate further increases the amount of waterproof glue located on the outside of the bottom plate. When the bottom plate bends back to its original position, it pushes the waterproof glue to move outward, further promoting the waterproof glue to escape outward.

[0075] Further, if Figure 12 As shown, the sealing component 43 includes a template 431 arranged above the fastening component 42 and controlled to move horizontally by an electric cylinder, a plurality of molding grooves 432 are arranged on the template 431 and the inner surfaces of the molding grooves 432 are all provided with heating wires, the lower bottom surface of the molding groove 432 is provided with a slide plate 433 controlled to move by an electric cylinder, a heater 434 arranged above the molding groove 432 and controlled to rotate up and down by a motor, and multiple groups of filling pieces 425 arranged on the template 431.

[0076] In this embodiment, the waterproof film is formed by providing a template 431 and a forming groove 432 .

[0077] In detail, for the sealing of screw holes, a method is usually adopted in which waterproof glue is directly dripped into the air of the screw and then tightened. A seal is formed after the waterproof glue dries. In this method, the waterproof glue fills the screw hole, which is not conducive to disassembly when problems arise during the subsequent use of the line board. The sealing component 43 is provided with a template 431 and a forming groove 432, and a coating roller 324 is used to apply a layer of waterproof glue in the forming groove 432, and then the waterproof glue is quickly heated to turn it into a barrel-shaped isolation layer, and the isolation layer is filled into the screw hole for tightening the screw, and then the waterproof glue is injected above the isolation layer, and the waterproof glue is isolated from the screw by the isolation layer, and a seal is formed at the opening of the screw hole.

[0078] Here, the molding groove 432 is moved to the bottom of the coating roller 324 by the movement of the template 431. At this time, the coating roller 324 completes the glue injection in the installation groove and is located above the template 431. The coating roller 324 enters the molding groove 432. Taking the movement of the template 431 as the X-axis, the movement direction of a group of glue injection tubes 322 closest to the sealing component 43 is the Y-axis perpendicular to the X-axis. The glue injection tubes 322 and the template 431 move simultaneously, so that the coating roller 324 applies a layer of waterproof glue on the inner wall of the molding groove 432 and the upper surface of the slide 433 below. Then the template 431 moves away from the coating roller 324, and the heater 434 moves into the molding groove 432, and cooperates with the heating wire to perform rapid heating to form an isolation layer. The slide 433 below moves to turn the molding groove 432 into a through hole, and the formed isolation layer is plugged into the screw hole using the filler 425.

[0079] It should be noted that the surfaces of the molding groove 432 and the slide plate 433 need to be set to smooth surfaces that do not adhere to the waterproof glue. This can be achieved by using special ceramic or glass materials, or by coating a release agent on the surface. This can be achieved by various methods, which are not explained here.

[0080] Further, if Figure 12 、 Figure 13 、 Figure 14 As shown, the number of the filling pieces 425 corresponds to the molding groove 432, and each group of filling pieces 425 includes a push block 426 arranged above the molding groove 432 and moved by an electric cylinder and a motor, a plurality of groups of annular air bags 427 arranged on the edge of the push block 426 and controlled to be inflated and deflated by an air pump, and a glue coating ring 428 and a glue outlet 429 arranged at the bottom of the template 431.

[0081] The up and down movement of the pusher block 426 is controlled by multiple electric cylinders, which are fixedly connected to each other and rotatably connected to the mold plate 431 via a motor. When glue is injected into the molding groove 432, the motor drives the pusher block 426 to rotate, turning it toward the outside of the mold plate 431 to prevent the filler 425 from interfering with the coating assembly 32. The pusher block 426 rotates back after glue application is completed.

[0082] In this embodiment, by setting a filling piece 425, the isolation layer is stuffed into the screw hole, the push block 426 penetrates into the middle of the isolation layer, the annular airbag 427 is inflated to fix the isolation layer, and the isolation layer is pushed downward out of the molding groove 432, and then passes through the glue coating ring 428 set below. The inner side of the glue coating ring 428 is provided with a glue outlet, and a layer of waterproof glue can be applied to the surface of the isolation layer, and then continue to move downward to stuff the isolation layer into the screw hole, and then the glue outlet 429 is filled with waterproof glue to achieve complete sealing.

[0083] In detail, since the isolation layer is relatively fragile, a push block 426 is provided. The diameter of the push block 426 is small, and it can penetrate into the isolation layer. Then the airbag is inflated to fix the isolation layer. Then, waterproof glue is coated on the isolation layer. On the one hand, a small amount of waterproof glue can fix the isolation layer on the screw hole. On the other hand, the waterproof glue can provide a certain degree of protection for the isolation layer to prevent the isolation layer from breaking when it is inserted into the screw hole.

[0084] In the description of the present invention, it should be understood that the terms "front and back", "left and right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings.
