[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0048] The automobile nozzle waterproof cover of the present invention is a part of the nozzle of the combustion engine of a new energy automobile, and is mainly used to prevent dust and debris from entering the interior of the nozzle, thereby preventing blockage and ensuring the water spraying effect, ensuring the normal operation of the water spraying function, and can also maintain sealing in a high temperature environment to prevent antifreeze leakage;

[0049] The automobile nozzle waterproof cover assembly device of the present invention belongs to a part of the intelligent manufacturing equipment industry, is one of the devices used to assemble the nozzle of the combustion engine of a new energy vehicle, and is mainly used for automatically assembling the waterproof cover on the nozzle.

[0050] Refer to the instruction manual Figure 1-4 The present invention provides a waterproof cover for a nozzle of an automobile, comprising an upper cover 1, a coil 2 and a lower cover 3. The bottom end of the outer peripheral surface of the upper cover 1 is integrally formed with three T-shaped protrusions 101 evenly distributed in an annular shape, and the top surface of the lower cover is integrally formed with a side arc plate 301 at a position corresponding to each T-shaped protrusion 101, and an oblique stopper 302 is fixedly provided at the top end of the inner side of each side arc plate 301. Three notches 304 and a clamping groove 303 are penetrated at the edge position of the top end of the lower cover 3, and the clamping groove 303 is located in the middle position between two of the notches 304, and a clamping plate 102 is integrally formed at a position corresponding to the clamping groove 303 on the outer side of the upper cover 1.

[0051] It should be noted that in the process of producing the nozzle waterproof cover, the coil 2 is first pressed into the interior of the upper cover 1, and then the inclined block 302 on the lower cover 3 is matched one by one with the T-shaped protrusion 101 on the upper cover 1. At the same time, the card slot 303 on the lower cover 3 is directly opposite to the card plate 102 on the upper cover 1. Finally, the upper cover 1 and the lower cover 3 are pressed together. At this time, there will be no dislocation between the upper cover 1 and the lower cover 3, and the assembly is convenient and the stability is good.

[0052] Refer to the instruction manual Figure 5-6 The present invention also provides an assembly device for a waterproof cover for a nozzle of an automobile, which is used to realize the assembly of the waterproof cover for a nozzle of an automobile, and comprises a machine base 4, a mounting frame 5 of an L-shaped structure is fixedly provided on one side of the machine base 4, a reciprocating mechanism 6 is provided on the inner side of the mounting frame 5, an upper cover feeding mechanism 7 is provided at the position of the top of the machine base 4 corresponding to the reciprocating mechanism 6, a coil feeding mechanism 8 and a lower cover feeding mechanism 9 are provided on the top of the machine base 4 from left to right in sequence, and a feeding assembly is provided at the discharge end of the coil feeding mechanism 8 and the lower cover feeding mechanism 9;

[0053] The coil feeding mechanism 8 and the lower cover feeding mechanism 9 are both composed of a discharge part and a screening part. The upper cover 1, the coil 2 and the lower cover 3 are fed by the upper cover feeding mechanism 7, the coil feeding mechanism 8 and the lower cover feeding mechanism 9 respectively.

[0054] It should be noted that in the process of assembling the above-mentioned nozzle waterproof cover, the upper cover 1, coil 2 and lower cover 3 are automatically fed respectively through the upper cover feeding mechanism 7, the coil feeding mechanism 8 and the lower cover feeding mechanism 9, and then the reciprocating motion mechanism 6 moves left and right and up and down to complete the collection of the coil 2 and the lower cover 3, and sequentially crimped to the upper cover 1. In the process of automatic feeding of the coil 2 and the lower cover 3, the coil 2 and the lower cover 3 with incorrect discharge position will also be removed to ensure the smooth progress of the crimping process.

[0055] Specifically, Figure 5 and Figure 7-9 As shown, the reciprocating mechanism 6 includes an L-shaped slide 61 slidably mounted on the top of the machine base 4 and columns 62 respectively fixed at both ends of the inner top end surface of the mounting frame 5, a shaft driven by a motor is installed in the middle of the inner side of the mounting frame 5, and a second disk 64 and a first disk 63 are respectively fixedly sleeved on the outer circumference of the shaft corresponding to the inner and outer sides of the L-shaped slide 61, and an L-shaped swing rod 67 and a straight swing rod 610 are respectively rotatably mounted on the sides of the two columns 62 facing the first disk 63 through a core rod, and a regular triangle groove 65 and a rhombus groove 66 are respectively opened on the sides of the first disk 63 and the second disk 64 facing the L-shaped slide 61, and a straight guide groove 68 and a trapezoidal groove 612 are respectively opened on the inner and outer sides of the vertical section of the L-shaped slide 61;

[0056] A round rod 69 is fixedly provided on the opposite sides of both ends of the L-shaped swing arm 67, and the opposite ends of the two round rods 69 are respectively slidably connected to the inside of the equilateral triangle groove 65 and the straight guide groove 68. A lifting plate 613 is provided on the outer side of the vertical section of the L-shaped slide 61 and is slidably installed in the inside of the trapezoidal groove 612. A sliding groove 614 is provided on one side of the lifting plate 613. A round rod 611 is fixedly passed through one end of the straight swing arm 610 away from the column 62 where it is located, and the two ends of the round rod 611 are respectively slidably connected to the inside of the sliding groove 614 and the diamond groove 66.

[0057] It should be noted that the equilateral triangle groove 65 is eccentrically arranged relative to the disk 1 63, so as to control the L-shaped rocker arm 67 to swing left and right with the core rod on the column 62 at its corresponding position as the center axis, while the diamond groove 66 is concentrically arranged relative to the disk 2 64, so as to control the straight rocker arm 610 to swing up and down with the core rod on the column 62 at its corresponding position as the center axis; the L-shaped slide 61 and the machine base 4 are limited by dovetail grooves and dovetail blocks to prevent the L-shaped slide 61 from being dislocated during movement.

[0058] In the process of controlling the reciprocating mechanism 6 to continuously move left and right and up and down, the motor drives the shaft to rotate, thereby driving the disc 1 63 and the disc 2 64 to rotate synchronously. During this period, when the disc 1 63 rotates, the round rod 1 69 with one end extending to the inside of the regular triangle groove 65 will move along the regular triangle groove 65, thereby driving the L-shaped swing rod 67 to swing left and right with the core rod on the column 62 at its corresponding position as the central axis, thereby driving the other round rod 1 69 (one end extending to the inside of the straight guide groove 68) to swing left and right, and the round rod 1 69 with one end extending to the inside of the straight guide groove 68 will push the L-shaped slide 61 to move linearly along the dovetail groove when it swings.

[0059] At the same time, when the second disk 64 rotates, the end of the second round rod 611 extending into the diamond groove 66 will move along the diamond groove 66, thereby driving the straight swing rod 610 to swing up and down with the core rod on the column 62 at its corresponding position as the central axis. In this process, since the other end of the second round rod 611 extends into the sliding groove 614 on the lifting plate 613, when the straight swing rod 610 swings up and down with the core rod on the column 62 at its corresponding position as the central axis, it will push the lifting plate 613 to move up and down in the vertical direction along the vertically arranged trapezoidal groove 612;

[0060] In the above movement process, when the L-shaped slide 61 moves leftward or rightward, the lifting plate 613 will simultaneously move up and down.

[0061] Specifically, Figure 5 and Figure 9-10 As shown, a strip plate 615 is fixedly provided at the bottom of the lifting plate 613, and a coil material picking assembly 616 and a lower cover material picking assembly 617 are respectively provided at both ends of the strip plate 615. The coil material picking assembly 616 includes a square column 1 fixedly provided at the bottom of the strip plate 615, and the lower cover material picking assembly 617 includes a circular plate rotatably installed at the bottom of the strip plate 615. A square column 2 is fixedly provided at the center position of the bottom of the circular plate, and an ultrasonic detector 17 is fixedly installed at one end of the bottom of the strip plate 615 close to the circular plate. Clamping parts are provided at the bottom ends of the square column 1 and the square column 2, and the two clamping parts include a cylinder 3 15 fixed at the bottom end of the side surface of the square column 1 and the square column 2, and the telescopic end of each cylinder 3 15 is fixedly connected with an L-shaped clamping plate 16.

[0062] It should be noted that when the cylinder 3 15 is in the initial state (i.e., the telescopic end is in the unextended state), the diameter of the circumscribed circle of the rectangular cavity formed by the four L-shaped clamping plates 16 corresponding to the coil material taking assembly 616 and the lower cover material taking assembly 617 is smaller than the inner ring diameter of the coil 2 and the lower cover 3, respectively. In the process of the lifting plate 613 moving left and right and up and down under the action of the reciprocating motion mechanism 6, the strip plate 615 will move synchronously with the lifting plate 613. When the strip plate 615 moves to the left (refer to the attached manual), the strip plate 615 moves to the left and right (refer to the attached manual). Figure 5 ) moves, the coil picking assembly 616 and the lower cover picking assembly 617 will move to the upper part of the position, and in the process of downward movement, the coil picking assembly 616 and the lower cover picking assembly 617 will move downward synchronously, and use their corresponding clamping parts to clamp the coil 2 and the lower cover 3 respectively. When the strip plate 615 moves to the right, the coil picking assembly 616 and the lower cover picking assembly 617 will switch to the upper part of the corresponding upper cover 1, and in the process of downward movement, the coil 2 and the lower cover 3 will be pressed onto the upper cover 1 at the corresponding position respectively;

[0063] In the above process, when the ultrasonic detector 17 detects that each time it moves to the left and moves downward, the control end will control the clamping part of the coil picking assembly 616 to complete a picking, and then in the process of moving to the right and moving downward, complete the crimping between the coil 2 and the corresponding upper cover 1. However, after the control end controls the clamping part of the lower cover picking assembly 617 to complete a picking, if the ultrasonic detector 17 does not detect that the upper cover 1 after the crimping coil 2 moves to the crimping position when moving to the right and moving downward, the clamping part will not release the clamping of the lower cover 3, but complete an air compression, until it is detected that the upper cover 1 after the crimping coil 2 moves to the crimping position, the lower cover picking assembly 617 will complete the synchronous picking and crimping with the coil picking assembly 616;

[0064] Furthermore, in the above process, when the clamping part is used to clamp the coil 2 or the lower cover 3, the L-shaped clamping plate 16 is pushed by the cylinder 3 15 to press against the inner surface of the coil 2 or the lower cover 3.

[0065] Specifically, Figure 6 and Figure 13-14 As shown, the two feeding assemblies include a lifting platform 10 arranged on the top of the machine base 4, two sets of spring telescopic rods 11 are fixedly connected between the two lifting platforms 10 and the machine base 4, and enclosures 12 are fixedly provided on the tops of the two lifting platforms 10. The two enclosures 12 are provided with feeding ports 14 at the discharge ends of the coil feeding mechanism 8 and the discharge ends of the lower cover feeding mechanism 9 corresponding to the two enclosures 12. The middle part of the top surface of the two lifting platforms 10 is also provided with an embedding groove, and the two embedding grooves are installed with a feeding belt 13 driven by a motor.

[0066] It should be noted that the spring telescopic rod 11 is composed of a sleeve fixedly connected to the machine base 4, a sleeve rod fixedly connected to the lifting platform 10, and a connecting spring fixedly connected between the machine base 4 and the lifting platform 10, and the bottom end of the sleeve rod is always kept inserted into the sleeve, and the connecting spring is sleeved on the outside of the sleeve and the sleeve rod. When feeding the coil 2 and the lower cover 3, the conveyor belt 13 is used to transport the coil 2 and the lower cover 3 that have slipped to the inside of the corresponding enclosure 12 to the material taking station. Since one end of the feeding assembly corresponding to the lower cover feeding mechanism 9 is always under the strip plate 615, each time the strip plate 615 moves downward to complete the crimping action, it will press the corresponding lifting platform 10 downward and compress the spring telescopic rod 11. However, in this process, the part of the enclosure 12 corresponding to the position of the feeding port 14 will prevent the lower cover 3 from continuing to slide into the enclosure or slide out of the range of the lifting platform 10.

[0067] Specifically, Figure 5 and Figure 11-12 As shown, the upper cover feeding mechanism 7 includes a T-shaped guide groove 71 which passes through the top of the machine base 4, and a T-shaped tooth plate 72 is slidably installed inside the T-shaped guide groove 71. A group of gears 73 meshing with the T-shaped tooth plate 72 are installed at positions on both sides of the T-shaped tooth plate 72 inside the T-shaped guide groove 71, with two gears in each group. A driving part 74 for driving the gear 73 to rotate is arranged at positions at the bottom of the machine base 4 corresponding to the two groups of gears 73, and a plurality of supporting cavities arranged equidistantly are opened in the middle of the top end surface of the T-shaped tooth plate 72.

[0068] It should be noted that in order to reduce the resistance encountered by the T-shaped tooth plate 72 during the conveying process, balls can be rolled and embedded in the part where the surface of the T-shaped tooth plate 72 contacts the inner surface of the T-shaped guide groove 71. At the same time, the driving part 74 adopts a step-by-step driving design, wherein, in the process of feeding the upper cover 1, the upper cover 1 is first placed in each supporting cavity on the T-shaped tooth plate 72 in turn, and then the gear 73 at the corresponding position is driven to rotate by the driving part 74, and the rotating gear 73 is used to drive the T-shaped tooth plate 72 carrying the upper cover 1 to convey towards each other.

[0069] Specifically, Figure 5 and Fig.13 As shown, the discharge part of the coil feeding mechanism 8 includes a material box 81 fixedly arranged on the top of the machine base 4 and a sink 82 opened on the top surface of the machine base 4. A lifting block 84 is inserted into the middle of the inner bottom of the material box 81 in a through-type movable manner, and a cylinder 83 is fixedly installed between the lifting block 84 and the inner bottom end surface of the sink 82.

[0070] The screening part of the coil feeding mechanism 8 includes a horizontal plate 85 fixedly arranged in the middle of the top of the inner cavity of a material box 81, a clamp 86 and a CCD camera 87 are installed at the bottom of the horizontal plate 85, a discharge trough 88 is provided on the side of the material box 81 facing the feeding component at the location, and an inclined material guide rack 89 is fixedly arranged at the position of the surface of the material box 81 corresponding to the discharge trough 88, and the lower end of the material guide rack 89 is in contact with one side of the lifting platform 10 on the feeding component at the location.

[0071] It should be noted that the top surface of the lifting block 84 is inclined and has a groove for discharging the coil 2. When the lifting block 84 rises to the highest position, the groove at the top is connected to the discharge slot 88. In the process of supplying the coil 2, the cylinder 83 drives the lifting block 84 to move downward, so that the coil 2 inside the material box 81 is submerged above the top of the lifting block 84. Then, as the lifting block 84 moves upward, the coil 2 is discharged inside the groove at the top, and moves upward to the discharge slot 88 and is discharged onto the guide rack 89, and then slides along the guide rack 89 to the top of the corresponding lifting platform 10.

[0072] Before the coil 2 is placed on the top of the lifting block 84 and moves upward to the discharge trough 88, the CCD camera 87 installed on the horizontal plate 85 will be used to detect whether there is an inverted coil 2. If so, it will be clamped out by the clamp 86 and placed again in the material box 81 to wait for the next round of discharge.

[0073] Specifically, Figure 5 and Fig.14 As shown, the discharge part of the lower cover feeding mechanism 9 includes a material box 91 fixedly arranged on the top of the machine base 4 and a sink 92 opened on the top surface of the machine base 4. A lifting block 94 is inserted into the middle of the inner bottom of the material box 91 in a through-type movable manner. A cylinder 93 is fixedly installed between the lifting block 94 and the inner bottom end surface of the sink 92.

[0074] The screening part of the lower cover feeding mechanism 9 includes a discharge chute 95 opened on the side of the material box 91 facing the feeding component at the location, and a guide rack 96 is fixedly provided with an inclined arrangement at the position of the surface of the material box 91 corresponding to the discharge chute 95, and the lower end of the guide rack 96 is in contact with one side of the lifting platform 10 on the feeding component at the location, and ear plates are fixedly provided at positions on both sides of the top of the discharge chute 95 on the surface of the material box 91 corresponding to the top, and guide rods 97 are fixedly provided on the two ear plates facing the feeding component at the location, and a guide platform 98 is provided at the top of the guide rack 96 corresponding to the lower end of the guide rod 97, and the guide platform 98 is fixed to the top of the machine base 4 through foot columns.

[0075] It should be noted that the top surface of the lifting block 94 is also inclined and is provided with a groove for discharging the lower cover 3. When the lifting block 94 rises to the highest position, the groove at its top is connected to the discharge chute 95. In addition, the spacing between the two guide rods 97 is larger than the outer diameter of the small diameter end of the lower cover 3 and smaller than the outer diameter of the large diameter end of the lower cover 3. In the process of supplying the lower cover 3, the lifting block 94 is driven downward by the cylinder 93 to allow the lower cover 3 inside the material box 91 to pass over the top of the lifting block 94. Then, as the lifting block 94 moves upward, the lower cover 3 is discharged inside the groove at its top and moves upward to the discharge chute 95 to be discharged onto the guide rack 96, and then slides along the guide rack 96 to the top of the corresponding lifting platform 10.

[0076] When the lower cover 3 is discharged at the top of the lifting block 94 and moves upward to the discharge trough 95, since the large diameter end and the small diameter end of the lower cover 3 will face upward during the discharge process, and when the lower cover 3 is in the state of the large diameter end facing upward, the lower end surface of the large diameter end is located above the guide rod 97, so that in the process of the discharged lower cover 3 being discharged to the guide rack 96, the lower cover 3 with the large diameter end facing upward will gradually break away from the guide rack 96 under the restriction of the guide rod 97, and slide along the guide rod 97 to the material guide platform 98, and then slide to the spare material receiving box (not shown) for collection, and then transferred to the inside of the material box 91 to wait for discharge again.
