Description

Technical Field

[0001] The invention relates to the technical field of hook production, in particular to a full-automatic hook assembly machine. Background Art

[0002] In daily life, hooks are often used. Generally, hooks are installed on the walls of kitchens, bathrooms and rooms in the home to hang some items. Earlier hooks were installed on the wall with self-tapping screws or nails. After removal, there would be screw holes on the wall, which was very unsightly. Now most families use suction cup hooks to hang items on the wall through the suction of the suction cup. Some hooks are generally assembled by a hook body and a fixing plate through a machine;

[0003] Referring to a Chinese patent with application number 201510310179.5, a riveting device for elastic hooks is disclosed, which can replace manual labor to realize automated production, which is safe and reliable, with high production efficiency, stable quality and low cost, and is suitable for promotion and application in the production and assembly line of elastic hooks. However, it is not easy to accurately control the riveting force of the cylinder, and some plastic hooks with poor strength and elasticity are prone to cracks and surface scratches during the riveting process.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

[0061] 1. In the present invention, the loading of the hook assembly is automatically completed through the No. 1 loading station and the No. 2 loading station. At the same time, the No. 2 loading station preliminarily assembles the hook assembly and cooperates with the assembly template to position the hook assembly parts.

[0062] 2. In the present invention, after the hook body is transported to the No. 2 assembly station by the station switching mechanism, the two extrusion blocks rotate in opposite directions, and the two extrusion blocks rotate to extrude the outer walls on both sides of the hook body located inside the No. 1 mold cavity, so that the other end of the hook body located inside the No. 1 mold cavity is opened for a distance, which makes it easier to place the fixing plate inside the hook body. Compared with the press-in assembly method, it can avoid the problem of surface damage caused by pressure between the fixing plate and the hook body, thereby improving the yield rate of the hook assembly and the aesthetics of the product.

[0063] 3. In the present invention, when the assembly template moves toward the pressing station, the sliding pin at the bottom thereof passes over the position of the protruding block and re-enters the interior of the path groove. Therefore, the thrust effect on the sliding pin ends, and the squeezing effect of the two squeezing blocks on the outer side of the hook body disappears. Under the action of the rebound force of the hook body itself, the opened end will recover, thereby engaging with the periphery of the fixed plate to achieve fixation between the two.

[0080] For further details, please refer to Figure 1 , Figure 2 As shown:

[0081] The No. 1 loading station 200 includes a No. 1 column 201, a No. 1 fixed plate 202, a No. 1 horizontal push cylinder 203, a No. 1 vertical push cylinder 204 and a No. 1 gripper cylinder 205. The No. 1 column 201 is fixedly installed on the top of the profile rack 100, and the number is two. The No. 1 fixed plate 202 is fixedly installed on the top of the two No. 1 columns 201. The No. 1 horizontal push cylinder 203 is fixedly installed on the top of the No. 1 fixed plate 202. The No. 1 vertical push cylinder 204 is fixedly installed on the output end of the No. 1 horizontal push cylinder 203. The No. 1 gripper cylinder 205 is fixedly installed on the output end of the No. 1 vertical push cylinder 204.

[0082] The output end of the No. 1 vibration loading tray 600 is located between the two No. 1 columns 201 , and the position of the output end of the No. 1 vibration loading tray 600 corresponds to the position of the No. 1 clamping cylinder 205 .

[0083] Specifically, the hook body is transported to the bottom of the No. 1 clamping cylinder 205 through the No. 1 vibrating loading tray 600, and the No. 1 clamping cylinder 205 is pushed downward by the output rod of the No. 1 vertical pushing cylinder 204. Then, the No. 1 clamping cylinder 205 clamps a hook body on the output end of the No. 1 vibrating loading tray 600. Then, the output rod of the No. 1 vertical pushing cylinder 204 pushes the No. 1 clamping cylinder 205 and the clamped hook body to move upward to the top dead center position of the output rod of the No. 1 vertical pushing cylinder 204. Then, The output rod of No. 1 horizontal push cylinder 203 extends out, pushing No. 1 vertical push cylinder 204, No. 1 clamping claw cylinder 205 and the clamped hook body to move to the top of a No. 1 horizontal push cylinder 203 close to the position. Then, the output rod of No. 1 vertical push cylinder 204 pushes No. 1 clamping claw cylinder 205 and the clamped hook body downward to place the hook body on the work station switching mechanism 500. The work station switching mechanism 500 is rotated to transport the hook body to the No. 2 loading station 300.

[0084] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown:

[0085] The second loading station 300 includes a second column 301, a second fixed plate 302, a second horizontal push cylinder 303, a second vertical push cylinder 304, a sinker plate 305 and a suction cup 306. The second column 301 is fixedly installed on the top of the profile rack 100, and there are two of them. The second fixed plate 302 is fixedly installed on the top of two second columns 301. The second horizontal push cylinder 303 is fixedly installed on the top of the second fixed plate 302. The second vertical push cylinder 304 is fixedly installed on the output end of the second horizontal push cylinder 303. The sinker plate 305 is fixedly installed on the output end of the second vertical push cylinder 304. The suction cup 306 is fixedly installed inside the sinker plate 305.

[0086] The output end of the No. 2 vibration loading tray 700 is located between the two No. 2 columns 301 , and the position of the output end of the No. 2 vibration loading tray 700 corresponds to the position of the suction cup 306 .

[0087] Specifically, when the hook body is transported to the No. 2 loading station 300, the output rod of the No. 2 vertical push cylinder 304 pushes the sinking plate 305 together with the suction cup 306 to move downward, and the suction cup 306 sucks a fixed plate on the output end of the No. 2 vibration loading tray 700, and then the output rod of the No. 2 vertical push cylinder 304 pushes the sinking plate 305, the suction cup 306 and the sucked fixed plate to move upward, and then the output rod of the No. 2 horizontal push cylinder 303 extends to push the No. 2 vertical push cylinder 304 , the sedimentation plate 305, the suction cup 306 and the sucked fixed plate move to the top of the assembly template 503, and then, the output rod of the No. 2 vertical push cylinder 304 pushes the sedimentation plate 305, the suction cup 306 and the sucked fixed plate downward again, and places the sucked fixed plate on the station switching mechanism 500, so that the fixed plate is initially stuck into the interior of the hook body, completing the preliminary assembly of the hook, and then, the station switching mechanism 500 transports the preliminarily assembled hook to the pressing station 900.

[0088] For further details, please refer to Fig.11 As shown:

[0089] The pressing station 900 includes a No. 4 column 901, a No. 4 fixed plate 902, a No. 4 vertical push cylinder 903 and a pressing block 904. The No. 4 column 901 is fixedly installed on the top of the profile rack 100, and there are two of them. The No. 4 fixed plate 902 is fixedly installed on the top of two No. 4 columns 901. The No. 4 vertical push cylinder 903 is fixedly installed on the top of the No. 4 fixed plate 902. The pressing block 904 is fixedly installed on the output end of the No. 4 fixed plate 902.

[0090] Specifically, when the hook that has been preliminarily assembled is transported to the pressing station 900 by the station switching mechanism 500, the output rod of the No. 4 vertical push cylinder 903 pushes the pressing block 904 to move downward, pressing the preliminarily assembled hook body and the fixed plate flat to form an assembled hook workpiece. Subsequently, the station switching mechanism 500 transports the assembled hook workpiece to the unloading station 400.

[0091] For further details, please refer to Figure 4 As shown:

[0092] The unloading station 400 includes a No. 3 column 401, a No. 3 fixed plate 402, a No. 3 horizontal push cylinder 403, a No. 3 vertical push cylinder 404 and a No. 3 clamping claw cylinder 405. The No. 3 column 401 is fixedly installed on the top of the profile rack 100, and there are two of them. The No. 3 fixed plate 402 is fixedly installed on the top of two No. 3 columns 401. The No. 3 horizontal push cylinder 403 is fixedly installed on the top of the No. 3 fixed plate 402. The No. 3 vertical push cylinder 404 is fixedly installed on the output end of the No. 3 horizontal push cylinder 403. The No. 3 clamping claw cylinder 405 is fixedly installed on the output end of the No. 3 vertical push cylinder 404.

[0093] Specifically, after the assembled hook workpiece is transported to the unloading station 400 by the station switching mechanism 500, the output rod of the No. 3 vertical push cylinder 404 pushes the No. 3 clamping cylinder 405 to move downward. After the assembled hook workpiece is clamped by the No. 3 clamping cylinder 405, the output rod of the No. 3 vertical push cylinder 404 immediately pushes the No. 3 clamping cylinder 405 and the clamped hook workpiece to move upward. After that, the output rod of the No. 3 horizontal push cylinder 403 retracts, driving the No. 3 vertical push cylinder 404, the No. 3 clamping cylinder 405 and the clamped hook workpiece to move to the top of the material guide trough plate 406. Subsequently, the output end of the No. 3 clamping cylinder 405 releases the clamping, and the hook workpiece falls into the inside of the material guide trough plate 406 under the action of gravity, and slides along the material guide trough plate 406 to the external collection frame, thus completing the assembly of the hook.

[0094] For further details, please refer to Figures 5 to 10 as well as Fig.12 As shown:

[0095] The station switching mechanism 500 includes a rotary cylinder 501, a turntable 502, an assembly template 503, a first mold cavity 504, a second mold cavity 505, a storage cavity 506, a vertical shaft 507, an extrusion block 508, an incomplete gear 509, a rack 5010, a push plate 5011, a sliding pin 5012, a fixing ring 5013, a path groove 5014, a protruding block 5015, a linear guide rail 5016, a linear slider 5017 and a support 5018. The turntable 502 is fixedly mounted on the output end of the rotary cylinder 501. The assembly template 503 is distributed at equal angles on the top of the turntable 502 and is fixed to the turntable 502 by bolts. The No. 1 mold cavity 504 is opened at one end of the top of the assembly template 503. The No. 2 mold cavity 505 is opened at the end of the top of the assembly template 503 away from the No. 1 mold cavity 504. The storage cavity 506 is opened on the inner walls of both sides of the No. 1 mold cavity 504. The vertical shaft 507 is vertically rotatably installed inside the assembly template 503 and is located inside the two storage cavities 506. The extrusion block 508 is fixedly installed on the upper part of the outer wall of the vertical shaft 507, and Located inside the storage chamber 506, the incomplete gear 509 is fixedly mounted on the lower part of the outer wall of the vertical shaft 507, the rack 5010 is meshed with the outer periphery of the incomplete gear 509, the push plate 5011 is fixedly mounted on the bottom of the two racks 5010, the sliding pin 5012 is fixedly mounted on the bottom of the push plate 5011, the fixing ring 5013 is fixedly mounted on the top of the profile frame 100 and is located at the bottom of the turntable 502, the path groove 5014 is opened on the top of the fixing ring 5013, and the path groove 5014 is close to the second feeding station 300 A raised block 5015 is provided on one side, a sliding pin 5012 is slidably installed inside the path groove 5014, a linear guide rail 5016 is fixedly installed at an equal angle at the bottom of the turntable 502, a linear slider 5017 is fixedly installed on the top of the push plate 5011 and is located between the two racks 5010, the linear slider 5017 is slidably installed on the periphery of the linear guide rail 5016, and a pillar 5018 is fixedly installed at an equal angle at the bottom of the turntable 502, and the bottom of the pillar 5018 is fixedly connected to the top of the profile frame 100 by bolts.

[0096] Specifically, the hook body is placed inside the No. 1 mold cavity 504 located at the bottom thereof through the No. 1 loading station 200. It should be noted that the specifications of the No. 1 mold cavity 504 are adapted to the hook body to be assembled, so that the hook body placed inside the No. 1 mold cavity 504 will not shake under the limiting effect of the inner wall of the No. 1 mold cavity 504, and the turntable 502 is driven to rotate by the output shaft of the rotating cylinder 501. The rotation of the turntable 502 further drives the assembly template 503 located at the top thereof to rotate together, and the assembly template 503 rotates through the No. 1 mold cavity 504 to drive the hook body located inside it to rotate together to the No. 2 loading station 300 and then stops rotating. Subsequently, the sucked fixed plate is placed inside the No. 2 mold cavity 505 through the No. 2 loading station 300. Since the starting specifications of the No. 2 mold cavity 505 are adapted to the specifications of the fixed plate, the fixed plate placed inside the No. 2 mold cavity 505 will not move under the limiting effect of the inner wall of the No. 2 mold cavity 505.

[0097] It should be noted that during the rotation of the assembly template 503, the vertical shaft 507, the incomplete gear 509, the rack 5010, the push plate 5011, the sliding pin 5012, the linear guide 5016 and the linear slider 5017 are also driven to rotate together, so that the sliding pin 5012 rotates along the inside of the path groove 5014. When the sliding pin 5012 rotates to the position of the protruding block 5015, the assembly template 503 just rotates to the second loading station 300, and after the sliding pin 5012 rotates to the position of the protruding block 5015, it is squeezed with the side wall of the protruding block 5015, and the sliding pin 5012 is moved closer to the fixing ring. 5013 is pushed in the direction of the center of the circle, further driving the push plate 5011 and the linear slider 5017 to slide along the linear guide rail 5016. At the same time, the sliding of the push plate 5011 drives the two racks 5010 connected thereto to slide together, and the two racks 5010 fixed on the top of the push plate 5011 have opposite teeth. Therefore, the movement of the two racks 5010 drives the two incomplete gears 509 to rotate in the opposite direction, further driving the two vertical shafts 507 and the two extrusion blocks 508 to rotate in the opposite direction. The two extrusion blocks 508 rotate to squeeze the outer walls on both sides of the hook body located inside the first mold cavity 504 (such as Fig.12 As shown in the figure, therefore, the other end of the hook body located inside the No. 1 mold cavity 504 is opened for a distance, which makes it easier to place the fixed plate inside the hook body. Compared with the press-in assembly method, it can avoid the problem of surface damage caused by the pressure between the fixed plate and the hook body, thereby improving the yield rate of the hook assembly and the aesthetics of the product. When the assembly template 503 moves toward the pressing station 900, the sliding pin 5012 at its bottom passes over the position of the protruding block 5015 and re-enters the path groove 5014. Therefore, the thrust effect of the sliding pin 5012 ends, and the squeezing effect of the two squeezing blocks 508 on the outside of the hook body disappears. Under the action of the rebound force of the hook body itself, the opened end will recover, thereby biting into the periphery of the fixed plate to achieve fixation between the two.

[0098] When the fully automatic hook assembly machine of the present scheme is working, the hook body is transported to the bottom of the No. 1 clamping cylinder 205 through the No. 1 vibrating feeding tray 600, and the No. 1 clamping cylinder 205 is pushed downward by the output rod of the No. 1 vertical pushing cylinder 204. Then, the No. 1 clamping cylinder 205 clamps a hook body on the output end of the No. 1 vibrating feeding tray 600. Then, the output rod of the No. 1 vertical pushing cylinder 204 pushes the No. 1 clamping cylinder 205 and the clamped hook body to move upward to the top dead center position of the output rod of the No. 1 vertical pushing cylinder 204. Then, the output rod of the No. 1 horizontal pushing cylinder 203 extends out. Push the No. 1 vertical push cylinder 204, the No. 1 clamping claw cylinder 205 and the clamped hook body to move to the top of a No. 1 horizontal push cylinder 203 near the position, and then, the output rod of the No. 1 vertical push cylinder 204 pushes the No. 1 clamping claw cylinder 205 and the clamped hook body downward to place the hook body inside the No. 1 mold cavity 504 located at the bottom thereof. It should be noted that the specifications of the No. 1 mold cavity 504 are adapted to the hook body to be assembled, so that the hook body placed inside the No. 1 mold cavity 504 will not shake under the limiting effect of the inner wall of the No. 1 mold cavity 504;

[0099] Then, the output shaft of the rotating cylinder 501 drives the turntable 502 to rotate, and the rotation of the turntable 502 further drives the assembly template 503 located on the top thereof to rotate together. The assembly template 503 rotates through the No. 1 mold cavity 504 and drives the hook body located inside thereof to rotate together to the No. 2 loading station 300 and then stops rotating. During the rotation of the assembly template 503, the vertical shaft 507, the incomplete gear 509, the rack 5010, the push plate 5011, the sliding pin 5012, the linear guide 5016 and the linear slider 5017 are also driven to rotate together, so that the sliding pin 5012 rotates along the inside of the path groove 5014. When the sliding pin 5012 rotates to the position of the protruding block 5015, the assembly template 503 just rotates to the No. 2 loading station 300. After the sliding pin 5012 rotates to the position of the protruding block 5015, it is squeezed with the side wall of the protruding block 5015, pushing the sliding pin 5012 toward the center of the fixed ring 5013, further driving the push plate 5011 and the linear slider 5017 to slide along the linear guide rail 5016. At the same time, the sliding of the push plate 5011 drives the two racks 5010 connected thereto to slide together, and the two racks 5010 fixed on the top of the push plate 5011 have opposite teeth. Therefore, the movement of the two racks 5010 drives the two incomplete gears 509 to rotate in the opposite direction, further driving the two vertical shafts 507 and the two extrusion blocks 508 to rotate in the opposite direction. The two extrusion blocks 508 rotate to squeeze the outer walls on both sides of the hook body located inside the first mold cavity 504 (such as Fig.12 As shown), the other end of the hook body located inside the first mold cavity 504 is opened a distance;

[0100] Subsequently, the output rod of the No. 2 vertical push cylinder 304 pushes the sinking plate 305 together with the suction cup 306 to move downward, and a fixed plate on the output end of the No. 2 vibrating loading tray 700 is sucked by the suction cup 306. Then, the output rod of the No. 2 vertical push cylinder 304 pushes the sinking plate 305, the suction cup 306 and the sucked fixed plate to move upward. Subsequently, the output rod of the No. 2 horizontal push cylinder 303 extends out, pushing the No. 2 vertical push cylinder 304, the sinking plate 305, the suction cup 306 and the sucked fixed plate to move toward the top of the assembly template 503. Then, the output rod of the No. 2 vertical push cylinder 304 pushes the sinking plate 305, the suction cup 306 and the sucked fixed plate again. The disk 306 and the sucked fixed plate move downward, and the sucked fixed plate is placed inside the second mold cavity 505. Since the actuation specifications of the second mold cavity 505 match those of the fixed plate, the fixed plate placed inside the second mold cavity 505 will not move under the limiting effect of the inner wall of the second mold cavity 505. During this period, since the end of the hook body is opened for a distance before this, it is easier to place the fixed plate inside the hook body. Compared with the press-in assembly method, the problem of surface damage caused by pressure between the fixed plate and the hook body can be avoided, thereby improving the yield rate of hook assembly and the aesthetics of the product.

[0101] Subsequently, the rotating cylinder 501 drives the turntable 502 to rotate again, further driving the assembly template 503 and the preliminarily assembled hook body and the fixed plate to rotate together to the pressing station 900 and then stop, and the output rod of the No. 4 vertical push cylinder 903 pushes the pressing block 904 to move downward, and the preliminarily assembled hook body and the fixed plate are pressed flat, and then, the output rod of the No. 4 vertical push cylinder 903 drives the pressing block 904 to move upward, and then, the output end of the rotating cylinder 501 drives the turntable 502 and the assembly template 503 to rotate, and the pressed and flat hook is transported to the unloading station 400, and then, the output rod of the No. 3 vertical push cylinder 404 pushes the No. 3 vertical push cylinder 404 to move upward, and then, the output rod of the No. 3 vertical push cylinder 404 drives ... The clamping cylinder 405 moves downward, and after the assembled hook workpiece is clamped by the No. 3 clamping cylinder 405, the output rod of the No. 3 vertical push cylinder 404 immediately pushes the No. 3 clamping cylinder 405 and the clamped hook workpiece to move upward. After that, the output rod of the No. 3 horizontal push cylinder 403 retracts, driving the No. 3 vertical push cylinder 404, the No. 3 clamping cylinder 405 and the clamped hook workpiece to move to the top of the material guide trough plate 406. Subsequently, the output end of the No. 3 clamping cylinder 405 releases the clamping, and the hook workpiece falls into the guide trough plate 406 under the action of gravity, and slides along the guide trough plate 406 to the external collection frame. In this way, the assembly of the hook is completed.

[0102] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
