A fully automatic hook assembly machine

Abstract

This invention relates to the field of hook production technology, specifically a fully automatic hook assembly machine, including a profile frame, a first feeding station, a second feeding station, an unloading station, a station switching mechanism, a first vibrating feeding plate, a second vibrating feeding plate, a PLC controller, and a pressing station. The first feeding station is fixedly located at the top right front end of the profile frame. After the hook body is transported to the second assembly station by the station switching mechanism, two extrusion blocks rotate in opposite directions, pressing the outer walls of both sides of the hook body located inside the first mold cavity. This causes the other end of the hook body inside the first mold cavity to open up a certain distance, making it easier to place the fixing plate inside the hook body. Compared with the press-in assembly method, this avoids surface damage caused by pressure between the fixing plate and the hook body, improving the yield rate of hook assembly and the aesthetics of the product.

Description

Technical Field

[0001] This invention relates to the field of hook production technology, specifically a fully automatic hook assembly machine. Background Technology

[0002] Hooks are frequently used in daily life. Generally, hooks are installed on the walls of kitchens, bathrooms and rooms in the home to hang some items. Early 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. Nowadays, most households use suction cup hooks, which hang items on the wall by the suction of the suction cup. Some hooks are generally assembled by machine from the hook body and the fixing plate.

[0003] Referring to a Chinese patent application number 201510310179.5, an elastic hook riveting device is disclosed, which can replace manual labor to achieve automated production. It is safe, reliable, efficient, stable in quality, and low in cost, and is suitable for promotion and application on the production and assembly line of elastic hooks. However, the riveting force of the cylinder is not easy to control precisely, and some plastic hooks with poor strength and elasticity are prone to cracks and surface scratches during the riveting process. Therefore, we propose a fully automatic hook assembly machine to solve the above-mentioned technical problems. Summary of the Invention

[0060] Compared with the prior art, the beneficial effects of the present invention are:

[0061] 1. In this invention, the hook assembly is automatically fed through the No. 1 and No. 2 feeding stations. At the same time, the No. 2 feeding station performs preliminary assembly of the hook assembly and positions the hook assembly parts with the help of the assembly template. This not only improves the assembly efficiency but also reduces the assembly error, thereby improving the product quality of the assembled hook.

[0062] 2. In this invention, after the hook body is transported to the second assembly station by the station switching mechanism, two extrusion blocks rotate in opposite directions. The two extrusion blocks rotate and extrude the outer walls of both sides of the hook body located inside the first mold cavity, so that the other end of the hook body located inside the first mold cavity opens up a certain distance, making it easier to place the fixing plate inside the hook body. Compared with the press-in assembly method, it can avoid the surface damage caused by pressure between the fixing plate and the hook body, and improve the yield rate of hook assembly and the aesthetics of the product.

[0063] 3. In this invention, during the movement of the assembly template to the pressing station, the sliding pin at its bottom passes the protruding block and re-enters the path groove. Therefore, the pushing force on the sliding pin ends, the squeezing force of the two squeezing blocks on the outside of the hook body disappears, and under the action of the rebound force of the hook body itself, the open end will return to its original position, thereby engaging with the periphery of the fixing plate and achieving fixation between the two.

The first feeding station 200 is fixedly located at the top right front end of the profile frame 100 for feeding the hook body. The second feeding station 300 is fixedly located at the top right end of the profile frame 100 for feeding the hook fixing plate. The pressing station 900... The 00 is fixedly installed at the top rear end of the profile frame 100 for hook assembly and pressing. The unloading station 400 is fixedly installed at the top left end of the profile frame 100 for hook unloading. The station switching mechanism 500 is fixedly installed at the top middle of the profile frame 100. The first vibrating feeding plate 600 is fixedly installed at the front right end of the profile frame 100. The second vibrating feeding plate 700 is fixedly installed at the right end of the profile frame 100. The PLC controller 800 is fixedly installed at the top left rear end of the profile frame 100 by a pole.

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

[0081] The No. 1 feeding station 200 includes a No. 1 column 201, a No. 1 fixing 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 frame 100, and there are two of them. The No. 1 fixing 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 fixing 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 vibrating feed plate 600 is located between the two No. 1 columns 201, and the position of the output end of the No. 1 vibrating feed plate 600 corresponds to the position of the No. 1 gripper cylinder 205.

[0083] Specifically, the hook body is conveyed to the bottom of the first gripper cylinder 205 by the first vibrating feeding plate 600. The output rod of the first vertical push cylinder 204 pushes the first gripper cylinder 205 downward. Then, the first gripper cylinder 205 clamps a hook body on the output end of the first vibrating feeding plate 600. Immediately afterwards, the output rod of the first vertical push cylinder 204 pushes the first gripper cylinder 205 and the clamped hook body upward to the upper stop position of the output rod of the first vertical push cylinder 204. Then, The output rod of the first horizontal push cylinder 203 extends, pushing the first vertical push cylinder 204, the first gripper cylinder 205, and the gripped hook body to move to the top of the first horizontal push cylinder 203 near that position. Immediately afterwards, the output rod of the first vertical push cylinder 204 pushes the first gripper cylinder 205 and the gripped hook body downward, placing the hook body on the station switching mechanism 500. By rotating the station switching mechanism 500, the hook body is transported to the second loading station 300.

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

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

[0086] The output end of the second vibrating feed plate 700 is located between the two second columns 301, and the position of the output end of the second vibrating feed plate 700 corresponds to the position of the suction cup 306.

[0087] Specifically, after the hook body is transported to the second loading station 300, the output rod of the second vertical push cylinder 304 pushes the settling plate 305 and the suction cup 306 downwards, and the suction cup 306 picks up a fixed plate on the output end of the second vibrating loading plate 700. Immediately afterwards, the output rod of the second vertical push cylinder 304 pushes the settling plate 305, the suction cup 306 and the picked-up fixed plate upwards. Subsequently, the output rod of the second horizontal push cylinder 303 extends, pushing the second vertical push cylinder 304. The settling plate 305, suction cup 306, and the fixed plate being sucked up move towards the top of the assembly template 503. Then, the output rod of the second vertical push cylinder 304 pushes the settling plate 305, suction cup 306, and the fixed plate being sucked up downwards again, placing the sucked fixed plate onto the station switching mechanism 500, so that the fixed plate is initially inserted into the interior of the hook body, completing the initial assembly of the hook. Subsequently, the station switching mechanism 500 transports the initially assembled hook to the pressing station 900.

[0088] For further details, please refer to [link / reference]. Figure 11 As shown:

[0089] The pressing station 900 includes four columns 901, four fixing plates 902, four vertical push cylinders 903, and a pressing block 904. Two columns 901 are fixedly installed on the top of the profile frame 100. Two fixing plates 902 are fixedly installed on the top of the two columns 901. The four vertical push cylinders 903 are fixedly installed on the top of the fixing plates 902. The pressing block 904 is fixedly installed at the output end of the fixing plates 902.

[0090] Specifically, after the hook that has been initially assembled is transported to the pressing station 900 by the station switching mechanism 500, the output rod of the fourth vertical push cylinder 903 pushes the pressing block 904 downward to press the initially assembled hook body and the fixing plate flat, forming the 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 [link / reference]. Figure 4 As shown:

[0092] The unloading station 400 includes a No. 3 column 401, a No. 3 fixing plate 402, a No. 3 horizontal push cylinder 403, a No. 3 vertical push cylinder 404, and a No. 3 gripper cylinder 405. The No. 3 column 401 is fixedly installed on the top of the profile frame 100, and there are two of them. The No. 3 fixing plate 402 is fixedly installed on the top of the two No. 3 columns 401. The No. 3 horizontal push cylinder 403 is fixedly installed on the top of the No. 3 fixing plate 402. The No. 3 vertical push cylinder 404 is fixedly installed at the output end of the No. 3 horizontal push cylinder 403. The No. 3 gripper cylinder 405 is fixedly installed at 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 third vertical push cylinder 404 pushes the third gripper cylinder 405 downward. After the third gripper cylinder 405 clamps the assembled hook workpiece, the output rod of the third vertical push cylinder 404 pushes the third gripper cylinder 405 and the clamped hook workpiece upward. Then, the output rod of the third horizontal push cylinder 403 retracts, causing the third vertical push cylinder 404, the third gripper cylinder 405 and the clamped hook workpiece to move to the top of the guide trough plate 406. Subsequently, the output end of the third gripper cylinder 405 releases the grip, and the hook workpiece falls into the guide trough plate 406 under the action of gravity and slides down the guide trough plate 406 into the outer collection frame, thus completing the assembly of the hook.

[0094] For further details, please refer to [link / reference]. Figures 5-10 as well as Figure 12 As shown:

[0095] The workstation 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 protrusion 5015, a linear guide rail 5016, a linear slider 5017, and a support column 5018. The turntable 502 is fixedly installed at the output end of the rotary cylinder 501. Assembly templates 503 are evenly distributed at the top of turntable 502 and fixed to turntable 502 by bolts. First mold cavity 504 is located at one end of the top of assembly template 503, and second mold cavity 505 is located at the end of the top of assembly template 503 away from first mold cavity 504. Receiving cavities 506 are located on the inner walls of both sides of first mold cavity 504. Vertical shaft 507 is vertically rotatably mounted inside assembly template 503 and located inside both receiving cavities 506. Extrusion block 508 is fixedly mounted on the upper part of the outer wall of vertical shaft 507. Located inside the receiving cavity 506, an incomplete gear 509 is fixedly installed on the lower part of the outer wall of the vertical shaft 507. A rack 5010 meshes with the incomplete gear 509. A push plate 5011 is fixedly installed at the bottom of the two racks 5010. A sliding pin 5012 is fixedly installed at the bottom of the push plate 5011. A fixing ring 5013 is fixedly installed on the top of the profile frame 100 and located at the bottom of the turntable 502. A path groove 5014 is formed on the top of the fixing ring 5013, and the path groove 5014 is close to the second loading station 300. A protrusion 5015 is provided on one side, a sliding pin 5012 is slidably installed inside the path groove 5014, linear guide rails 5016 are fixedly installed at equal angles at the bottom of the turntable 502, linear sliders 5017 are fixedly installed on the top of the push plate 5011 and located between the two racks 5010, linear sliders 5017 are slidably installed on the periphery of the linear guide rails 5016, and support columns 5018 are fixedly installed at equal angles at the bottom of the turntable 502, and the bottom of the support columns 5018 is fixedly connected to the top of the profile frame 100 by bolts.

[0096] Specifically, the hook body is placed into the first mold cavity 504 located at its bottom through the first loading station 200. It should be noted that the opening specifications of the first mold cavity 504 are adapted to the hook body to be assembled, so that the hook body placed inside the first mold cavity 504 will not shake under the limiting effect of the inner wall of the first mold cavity 504. The output shaft of the rotary cylinder 501 drives the turntable 502 to rotate. The rotation of the turntable 502 further drives the assembly template 503 located at its top to rotate together. The rotation of the assembly template 503 drives the hook body located inside the first mold cavity 504 to rotate together to the second loading station 300 and then stops rotating. Subsequently, the fixed plate picked up by the second loading station 300 is placed into the second mold cavity 505. Since the opening specifications of the second mold cavity 505 are adapted to the specifications 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.

[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 rail 5016, and the linear slider 5017 also rotate together. This causes the sliding pin 5012 to rotate along the inside of the path groove 5014. When the sliding pin 5012 rotates to the position of the protrusion 5015, the assembly template 503 has just rotated to the second loading station 300. After the sliding pin 5012 rotates to the position of the protrusion 5015, it is pressed against the side wall of the protrusion 5015, pushing the sliding pin 5012 closer to the fixing ring. Pushing 5013 in the center direction further drives the push plate 5011 and the linear slider 5017 to slide along the linear guide rail 5016. Simultaneously, the sliding of the push plate 5011 causes the two connected racks 5010 to slide together. Since the two racks 5010 fixed to the top of the push plate 5011 have opposite teeth, their movement causes the two incomplete gears 509 to rotate in opposite directions, further driving the two vertical shafts 507 and the two extrusion blocks 508 to rotate in opposite directions. The rotation of the two extrusion blocks 508 extrudes the outer walls on both sides of the hook body located inside the first mold cavity 504 (e.g., ...). Figure 12 As shown), the other end of the hook body located inside the first mold cavity 504 opens a certain distance, making it easier to place the fixing plate inside the hook body. Compared with the press-in assembly method, it can avoid surface damage caused by pressure between the fixing plate and the hook body, improve the yield rate of hook assembly and the aesthetics of the product. When the assembly template 503 moves to the pressing station 900, the sliding pin 5012 at its bottom passes the position of the protrusion 5015 and re-enters the path groove 5014. Therefore, the pushing force on the sliding pin 5012 ends, the squeezing force of the two extrusion blocks 508 on the outside of the hook body disappears, and under the action of the rebound force of the hook body itself, the opened end will return to its original position, thus engaging with the periphery of the fixing plate and achieving fixation between the two.

[0098] In this fully automatic hook assembly machine, the hook body is conveyed to the bottom of the gripper cylinder 205 by a vibrating feeding plate 600. The output rod of the vertical push cylinder 204 pushes the gripper cylinder 205 downwards, causing it to clamp a hook body from the output end of the vibrating feeding plate 600. Immediately afterward, the output rod of the vertical push cylinder 204 pushes the gripper cylinder 205 and the clamped hook body upwards to the upper stop position of the output rod. Then, the output rod of the horizontal push cylinder 203 extends. Push the No. 1 vertical push cylinder 204, the No. 1 gripper cylinder 205 and the gripped hook body to the top of the No. 1 horizontal push cylinder 203 near that position. Then, the output rod of the No. 1 vertical push cylinder 204 pushes the No. 1 gripper cylinder 205 and the gripped hook body downward to move them downward, placing the hook body into the No. 1 mold cavity 504 located at its bottom. It should be noted that the opening 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 action of the inner wall of the No. 1 mold cavity 504.

[0099] Next, the output shaft of the rotary cylinder 501 drives the turntable 502 to rotate. The rotation of the turntable 502 further drives the assembly template 503 located on top of it to rotate as well. The rotation of the assembly template 503 drives the hook body located inside the first mold cavity 504 to rotate to the second loading station 300 and then stops rotating. During the rotation of the assembly template 503, it also drives the vertical shaft 507, the incomplete gear 509, the rack 5010, the push plate 5011, the sliding pin 5012, the linear guide rail 5016, and the linear slider 5017 to rotate together, causing the sliding pin 5012 to rotate along the inside of the path groove 5014. When the sliding pin 5012 rotates to the position of the protrusion 5015, the assembly template 503 has just rotated to the second loading station 300. After the sliding pin 5012 rotates to the position of the protrusion 5015, it presses against the side wall of the protrusion 5015, pushing the sliding pin 5012 towards the center of the fixing ring 5013. This further drives 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 to it to slide together. The two racks 5010 fixed on the top of the push plate 5011 have opposite teeth, so the movement of the two racks 5010 drives the two incomplete gears 509 to rotate in opposite directions, which in turn drives the two vertical shafts 507 and the two extrusion blocks 508 to rotate in opposite directions. The rotation of the two extrusion blocks 508 extrudes the outer walls of the two sides of the hook body located inside the first mold cavity 504 (e.g., Figure 12 As shown in the figure, the other end of the hook body located inside the first mold cavity 504 opens a certain distance;

[0100] Subsequently, the output rod of the second vertical push cylinder 304 pushes the settling plate 305 and suction cup 306 downwards, and the suction cup 306 picks up a fixed plate on the output end of the second vibrating feed plate 700. Immediately afterwards, the output rod of the second vertical push cylinder 304 pushes the settling plate 305, suction cup 306, and the picked-up fixed plate upwards. Then, the output rod of the second horizontal push cylinder 303 extends, pushing the second vertical push cylinder 304, settling plate 305, suction cup 306, and the picked-up fixed plate upwards towards the top of the assembly template 503. Next, the output rod of the second vertical push cylinder 304 again pushes the settling plate 305, suction cup 306, and suction cup 306 upwards towards the top of the assembly template 503. The plate 306 and the suction-loaded fixing plate move downwards, placing the suction-loaded fixing plate inside the second mold cavity 505. Since the opening specifications of the second mold cavity 505 are compatible with the specifications of the fixing plate, the fixing plate placed inside the second mold cavity 505 will not move under the limiting action of the inner wall of the second mold cavity 505. During this process, since the end of the hook body is opened a certain distance beforehand, it is easier to place the fixing plate inside the hook body. Compared with the press-in assembly method, it can avoid surface damage caused by pressure between the fixing plate and the hook body, thereby improving the yield rate of hook assembly and the aesthetics of the product.

[0101] Subsequently, rotary cylinder 501 drives turntable 502 to rotate again, further rotating assembly template 503, the pre-assembled hook body, and fixing plate together to the pressing station 900 and then stopping. The output rod of vertical push cylinder 903 pushes pressing block 904 downwards, pressing the pre-assembled hook body and fixing plate flat. Then, the output rod of vertical push cylinder 903 drives pressing block 904 upwards. Next, the output end of rotary cylinder 501 drives turntable 502 and assembly template 503 to rotate, transporting the flattened hook to unloading station 400. Then, the output rod of vertical push cylinder 404 pushes... The gripper cylinder 405 moves downwards, and after the assembled hook workpiece is gripped by the third gripper cylinder 405, the output rod of the third vertical push cylinder 404 pushes the third gripper cylinder 405 and the gripped hook workpiece upwards. Then, the output rod of the third horizontal push cylinder 403 retracts, causing the third vertical push cylinder 404, the third gripper cylinder 405, and the gripped hook workpiece to move to the top of the guide trough plate 406. Subsequently, the output end of the third gripper cylinder 405 releases the grip, and the hook workpiece falls into the guide trough plate 406 under the action of gravity, and slides down the guide trough plate 406 into the outer collection frame. In this way, the assembly of the hook is completed.
