DETAILED DESCRIPTION

[0027] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1-10 As shown, a device for assembling a spring pin and a middle plate in a top-bottom hinge comprises a first assembly module 1, a transfer module 2 and a second assembly module 3;

[0029] The first assembly module 1 includes a turntable 11, a limit seat 12 and a limit nail feeding mechanism 13, wherein the limit seat 12 is arranged on the turntable 11, and the limit nail feeding mechanism 13 includes a clamping arm 132 and a discharge guide groove 131, wherein the clamping arm 132 is located between the discharge guide groove 131 and the turntable 11 to clamp the limit nail and insert it into the spring located in the limit seat 12; in this embodiment, Figure 6 As shown, the limit seat 12 is evenly distributed on the turntable 11, and is provided with a spring loading station 14, a limit pin installation station 15, an oiling station 16 and a blanking station 17. When the limit seat 12 rotates to a corresponding station, the limit seat 12 will be subjected to a corresponding process flow; wherein the spring loading station 14 is used to put a spring into the limit seat 12, the limit pin installation station 15 is used to insert a limit pin into the spring located in the limit seat 12, the oiling station 16 is used to align the head recess of the spring pin with oil, and the blanking station 17 is used to provide the assembled spring pin to the transfer module 2;

[0030] The transfer module 2 is located between the first assembly module 1 and the second assembly module 3. The second assembly module 3 includes a pressing mechanism 31, an oblique pushing mechanism 32 and an assembly seat 33. The transfer module 2 is used to transfer the spring nail from the first assembly module 1 to the middle plate located at the assembly seat 33.

[0031] The output end of the pressing mechanism 31 faces the tail of the limiting nail in the spring nail to press the tail of the limiting nail onto the positioning member on the right side of the middle plate, and to tilt the head of the limiting nail upward; the output end of the oblique pushing mechanism 32 faces the head of the limiting nail after tilting upward to push the head of the limiting nail into the middle plate.

[0032] In the assembling device of the spring nail and the middle plate in the hinge of heaven and earth, after placing the spring on the limiting seat 12, the turntable 11 drives the limiting seat 12 to rotate, thereby driving the spring to rotate. Then, after the clamping arm 132 clamps the limiting nail from the discharging guide groove 131, the limiting nail is inserted into the spring to form a spring nail; the transfer module 2 will remove the spring nail located on the limiting seat 12 of the turntable 11; at the same time, the middle plate will be loaded onto the assembling seat 33, and then the transfer module 2 can transfer the spring nail to the middle plate located on the assembling seat 33; subsequently, the tail of the limiting nail is pressed into the middle plate by the pressing mechanism 31, and then the head of the limiting nail is pushed into the middle plate by the oblique pushing mechanism 32, and the spring can enter the middle plate together with the limiting nail. Using automated equipment instead of manual operation improves the production efficiency.

[0033] Preferably, as Figure 5 shown, the limiting nail feeding mechanism 13 further includes a swing drive motor 133, and the output shaft of the swing drive motor 133 is fixedly connected to one end of the clamping arm 132 to drive the other end of the clamping arm 132 to swing, so that the other end of the clamping arm 132 faces the discharging guide groove 131 or the limiting seat 12.

[0034] In this embodiment, the clamping arm 132 includes a jaw cylinder 134, a jaw body 135 and a slide cylinder 136. The jaw cylinder 134 is connected to the jaw body 135 to achieve expansion and contraction. The swing drive motor 133 is connected to the slide cylinder 136, and the slide cylinder 136 is connected to the jaw cylinder 134 to drive the jaw cylinder 134 to move. The jaw body 135 faces the discharging guide groove 131 or the limiting seat 12, and the slide cylinder 136 drives the jaw body 135 to approach the discharging guide groove 131 or the limiting seat 12. As Figure 10As shown in the figure, when the jaw body 135 of the clamping arm 132 faces the discharge guide groove 131, under the action of the jaw cylinder 134, the jaw body 135 closes inward to clamp the limit pin. When clamping the limit pin, the spring member 1352 above the ejector pin 1351 in the jaw body 135 is compressed. Then, the swing drive motor 133 operates to drive the clamping arm 132 to swing. After the clamping arm 132 swings and the jaw body 135 faces the limit seat 12, the jaw cylinder 134 controls the jaw body 135 to open, and the compressed spring member 1352 above the ejector pin 1351 in the jaw body 135 is released. The spring force ejects the limit pin in front of the ejector pin 1351 into the spring of the limit seat 12.

[0035] It should be noted that, as Figure 7 shown, the transfer module 2 includes a claw 21, a horizontal guide rail 22, a slider 23, and a longitudinal cylinder 24. The horizontal guide rail 22 extends from the first assembly module 1 towards the second assembly module 3. The slider 23 is slidably connected to the horizontal guide rail 22. The slider 23 is provided with the longitudinal cylinder 24. The output shaft of the longitudinal cylinder 24 is perpendicular to the horizontal guide rail 22. The claw 21 is fixedly connected to the output shaft of the longitudinal cylinder 24. In this embodiment, the output shaft of the longitudinal cylinder 24 is connected to the claw 21 through a connecting plate to drive the claw 21 to move up and down.

[0036] After the claw 21 moves downward along the longitudinal cylinder 24, the spring pin can be taken out from the limit seat 12 of the turntable 11. Then, the claw 21 moves upward along the longitudinal cylinder 24, and then follows the slider 23 to move leftward along the horizontal guide rail 22, so that the claw 21 faces the assembly seat 33. Then, the longitudinal cylinder 24 drives the claw 21 to move downward, and then the claw 21 is released, and the spring pin can be placed on the middle plate of the assembly seat 33.

[0037] Optionally, as Figure 8 shown, the pressing mechanism 31 includes a lifting cylinder 311, a lifting seat 312, a pressing swing arm 313, a pressing block 314, and a telescopic cylinder 315. The output shaft of the lifting cylinder 311 extends downward and is connected to the lifting seat 312. One end of the pressing swing arm 313 is rotatably connected to the lifting seat 312. The other end of the pressing swing arm 313 is connected to the pressing block 314. The output shaft of the telescopic cylinder 315 is hinged to the other end of the pressing swing arm 313.

[0038] By driving the lifting seat 312 to descend by the lifting cylinder 311, the pressing swing arm 313 and the pressing block 314 can be continuously close to the assembly seat 33. By operating the telescopic cylinder 315, the pressing swing arm 313 can drive the pressing block 314 to swing, as Figure 7 and 8As shown, when the pressing swing arm 313 drives the pressing block 314 to swing clockwise, the pressing block 314 can press the tail of the limit pin in the spring pin from an inclined angle, so as to drive the tail of the limit pin into the middle plate.

[0039] Specifically, as Figure 9 shown, the oblique pushing mechanism 32 includes an oblique pushing block 321, an oblique pushing cylinder 322 and a spring push rod 325. The spring push rod 325 is inclined downward from top to bottom in the direction of the assembly seat 33. The oblique pushing block 321 is slidably connected to the spring push rod 325. The oblique pushing cylinder 322 is arranged on the spring push rod 325 and the output shaft of the oblique pushing cylinder 322 is fixedly connected to the oblique pushing block 321. After the head of the limit pin tilts upward, the whole spring pin is inclined downward from top to bottom to the right. At this time, the oblique pushing cylinder 322 drives the oblique pushing block 321 to act. Under the impact, the head of the limit pin can be driven into the middle plate to realize the assembly of the spring pin.

[0040] It should be noted that the oblique pushing mechanism 32 further includes an inclined base 323 and a driving cylinder 324. The spring push rod 325 is slidably arranged on the inclined base 323. The inclined base 323 is parallel to the spring push rod 325. The output shaft of the driving cylinder 324 is fixedly connected to the spring push rod 325, and the output shaft of the driving cylinder 324 is parallel to the length direction of the spring push rod 325. By arranging the driving cylinder 324 and driving the spring push rod 325 to move through the driving cylinder 324, the oblique pushing block 321 can first approach the assembly seat 33 and then drive the head of the limit pin into the middle plate, thereby shortening the stroke of the oblique pushing block 321.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations of these embodiments still fall within the protection scope of the present invention.
