Description

Technical Field

[0001] The present invention relates to the technical field of foot pad production equipment, and in particular to a fully automatic hot-melt equipment for foot pad production. Background Art

[0002] Bathrooms are mainly used for bathing, and the floors are usually smooth, so users need to be careful, otherwise they may fall. In particular, hotels often place anti-skid mats in the bathroom to prevent consumers from getting injured due to falls. The utility model patent with publication number CN201205183Y discloses a patch anti-skid bathroom mat. The bottom of the patch anti-skid bathroom mat is provided with a suction cup, which can be used to firmly connect the anti-skid mat to the bathroom floor to prevent the user from slipping due to the anti-skid mat itself sliding during use. The above-mentioned patch anti-skid bathroom mat is widely used due to its significant anti-skid effect, but in its production process, the suction cups are mostly arranged manually and then fused by a hot melt machine. In this way, not only is the production efficiency extremely low, but the position deviation of the suction cups is large, and the yield rate of the anti-skid mats produced is not high, which cannot meet the supply demand.

[0003] Refer to the invention patent with publication number CN208019657U, which discloses a suction cup assembly device for anti-slip mats. This device uses an automatic assembly machine to load the suction cups. Specifically, it loads the suction cups via a vibrating plate. The assembly lifting cylinder that moves in the X-axis direction drives the suction cups, and the Y-axis translation mechanism that moves in the Y-axis direction drives the movement of the anti-slip mats, thereby achieving automatic loading of the suction cups. This device achieves automatic loading of the suction cups, which greatly improves production efficiency compared to manual loading. However, its structure is complex and occupies too much space. In addition, the anti-slip mats require manual loading. After the suction cups are arranged, the mobile platform needs to be manually pushed onto the conveyor rack, resulting in low production efficiency.

[0004] Therefore, it is necessary to provide a technical solution to solve the above problems. Summary of the Invention

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In the description of the embodiments of the present invention, it should be understood that the directions or positional relationships indicated by “up”, “down”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0039] In order to more clearly illustrate the technical solution of the present invention, a preferred embodiment is provided below. Figures 1 to 8 A fully automatic hot-melt device for producing foot pads, comprising a high-frequency hot-melt machine 1, a suction cup feeding device 2, and a foam pad feeding device 3, wherein:

[0040] The high-frequency hot melt machine 1 is provided with a transverse frame 11, and the transverse frame 11 is provided with a processing table 12 and a driving mechanism for driving the processing table 12 to slide;

[0041] The suction cup loading device 2 is provided on one side of the high-frequency hot melt machine 1 and includes a suction cup placement mechanism 21 and a suction cup conveying robot arm 22. The suction cup placement mechanism 21 includes a centralizing table 211, a vibrating plate 212, and a SCARA robot 213. The SCARA robot 213 is used to convey the suction cups on the vibrating plate 212 to the centralizing table 211.

[0042] The foam pad feeding device 3 is arranged on the side of the high frequency hot melt machine 1 away from the suction cup feeding device 2, and includes a foam pad placement mechanism 31 and a foam pad conveying robot arm 32. The SCARA robot (Selective Compliance Assembly Robot Arm) is a robot arm used for assembly operations.

[0043] In this embodiment, a SCARA manipulator 213 is used for suction cup loading. The SCARA manipulator 213 has a compact structure and high flexibility. The use of the SCARA manipulator 213 for loading replaces the structure in the prior art in which the assembly lifting cylinder that moves in the X-axis and the Y-axis translation mechanism that moves in the Y-axis are used to cooperate with the loading structure. This can greatly reduce the space occupied by the suction cup loading device 2, thereby reducing the overall volume of the fully automatic hot melt equipment for the production of foot pads.

[0044] Furthermore, in this embodiment, the suction cup conveying robot 22 simultaneously moves the plurality of suction cups arranged on the central table 211 to the processing table 12, and the foam pad conveying robot 32 automatically conveys the foam pad to the processing table 12. The driving mechanism then drives the processing table 12 to move to the processing station of the high-frequency hot melt machine 1 for hot melt processing. The design of this application realizes automatic loading of suction cups and foam pads, requiring only manual removal of the fused finished product, significantly reducing labor costs, improving work efficiency, and producing a high yield rate of finished products.

[0045] The working process of the fully automatic hot melt equipment for producing foot pads involved in the present invention is as follows: the vibration plate 212 continuously transports the suction cups to its output rail through vibration, and the SCARA robot 213 drives the suction cups on the output rail of the vibration plate 212 and arranges them on the central table 211 according to a specific arrangement method. Then the suction cup conveying robot arm 22 takes out multiple suction cups on the central table 211 at one time and transports them to the processing table 12. Then the foam pad conveying robot arm 32 takes out the foam pad on the foam pad placement mechanism 31 and transports it to the processing table 12, and covers it on several suction cups. Finally, the driving mechanism drives the processing table 12 to move to the processing station of the high-frequency hot melt machine 1 for hot melt processing. After the suction cups and the anti-slip pads are fused, the driving mechanism drives the processing table 12 to move outward, and the finished anti-slip pads are taken away manually.

[0046] As a preferred solution of this embodiment, both ends of the transverse frame 11 extend to the outside of the high-frequency hot melt machine 1. Two processing tables 12 are installed on the transverse frame 11, and the driving mechanism is used to drive the two processing tables 12 to slide along the length direction of the transverse frame 11. In specific use, the two processing tables 12 work alternately. When any processing table 12 enters the processing station of the high-frequency hot melt machine 1 to perform hot melting work, the suction cup conveying robot arm 22 and the foam pad conveying robot arm 32 respectively convey the suction cup and the foam pad to the other processing table 12. In this way, when the high-frequency hot melt machine 1 completes the hot melting work of the suction cup and the foam pad on one processing table 12, the driving mechanism drives the positions of the two processing tables 12 to alternate, so that the processing table 12 with the finished product slides outward, and the finished anti-slip mat is manually taken out. At the same time, the other processing table 12 slides into the processing station of the high-frequency hot melt machine 1 to perform hot melting work. By adopting the above design, one processing table 12 is in the hot melting working state, and the other processing table 12 is in the loading and unloading state, which can greatly shorten the idle period of the high-frequency hot melting machine 1, the suction cup loading device 2 and the foam pad loading device 3, thereby improving the production efficiency of the foot pads.

[0047] Preferably, the drive mechanism includes a second motor, a first transmission belt, and two first transmission wheels; the two first transmission wheels are mounted on either end of the transverse frame 11, the first transmission belt being in transmission connection with the two first transmission wheels; the second motor is mounted on the transverse frame 11 and is used to drive either first transmission wheel to rotate; and the two processing tables 12 are each fixedly connected to the first transmission belt. With this design, when the second motor drives the first transmission wheels to rotate, the two processing tables 12 can be driven by the first transmission belt to slide synchronously, thereby achieving the effect of the two processing tables 12 alternately entering the processing station of the high-frequency hot melt machine 1.

[0048] Furthermore, the driving mechanism may also adopt other transmission structures, for example, a rack is installed on the processing table 12, a transmission gear is installed on the second motor, the transmission gear is engaged with the rack, and then the two processing tables 12 can be driven to slide under the drive of the second motor.

[0049] As another preferred solution, the driving mechanism includes two driving members, and the two processing tables 12 are driven to slide respectively by the two driving members.

[0050] As a preferred solution of this embodiment, two vibration plates 212 are provided, one on each side of the central platform 211, and two output rails are provided on the vibration plates 212. Four SCARA manipulators 213 are provided, and the four SCARA manipulators 213 are correspondingly located outside the output rails of the two vibration plates 212. Specifically, the design of four SCARA manipulators 213 further improves the efficiency of suction cup arrangement, while also meeting the suction cup arrangement requirements of anti-slip mats of different specifications.

[0051] As a preferred solution of this embodiment, the SCARA manipulator 213 includes a base 2131, a connecting arm 2132, an output seat 2133 and an output shaft 2134; the connecting arm 2132 is connected to the base 2131, and a first control component is provided inside the base 2131 for driving the connecting arm 2132 to rotate; the output seat 2133 is connected to the connecting arm 2132, and a second control component is provided inside the output seat 2133, and the second control component is used to drive the output seat 2133 to rotate relative to the connecting arm 2132; the output shaft 2134 is installed on the output seat 2133, and a third control component is provided inside the output seat 2133 for driving the output shaft 2134 to move up and down; a material picking component 2135 is installed on the output shaft 2134, and the material picking component 2135 is preferably a vacuum suction device. Specifically, the SCARA robot 213 is connected to a controller, which is programmed to drive the first control component and the second control component to start, so that the output shaft 2134 moves to the output rail of the vibration disk 212 and above the suction cup placement points of the centralizing table 211. Then, the controller drives the third control component to start, so as to drive the output shaft 2134 to rise and fall, so that the material picking component 2135 can pick up the suction cup on the output rail of the vibration disk 212 and place the suction cup on the point of the centralizing table 211.

[0052] Preferably, the first control member and the second control member are both reduction motors. The third control member includes a third motor, a second transmission belt, and two second transmission wheels; the two second transmission wheels are both rotatably connected to the inside of the output seat 2133; the second transmission belt is in transmission connection with the two second transmission wheels; the third motor is installed in the output seat 2133, which is used to drive any second transmission wheel to rotate; the output shaft 2134 is slidably connected to the output seat 2133, which can be raised and lowered and slid, and there is no relative rotation between the output shaft 2134 and the output seat 2133; the output shaft 2134 passes through the second transmission wheel away from the third motor and is threadedly connected to the second transmission wheel. After the third motor is started, the two second transmission wheels rotate synchronously, and with the threaded connection, the second transmission wheel can drive the output shaft 2134 to move up and down.

[0053] Preferably, in this embodiment, a limit block is mounted on the output shaft 2134, and a limit slot is provided in the output seat 2133. The limit block is slidably connected to the limit slot and can be raised and lowered and slid along the limit slot. This design prevents the output shaft 2134 from being driven to rotate by the second transmission wheel.

[0054] As a preferred solution of this embodiment, the suction cup conveying robot 22 includes a first bracket; the first bracket includes a first beam 222 and two first support columns 221, the first beam 222 is arranged above the centralizing platform 211 and is installed on the two first support columns 221; a first X-direction moving module 223 is installed on the first beam 222; a first Y-direction moving module 224 is provided on the first X-direction moving module 223; a first Z-direction moving module 225 is installed on the first Y-direction moving module 224; a first fixed plate 226 is installed at the bottom of the first Z-direction moving module 225, and a plurality of first vacuum suction heads 227 are installed on the first fixed plate 226. Specifically, the first X-axis movable module 223 can drive the first Y-axis movable module 224 to slide along the X-axis direction, the first Y-axis movable module 224 can drive the first Z-axis movable module 225 to slide along the Y-axis direction, and the first Z-axis movable module 225 can drive the first fixed plate 226 to move along the Z-axis direction. In this way, with the cooperation of the first X-axis movable module 223, the first Y-axis movable module 224, and the first Z-axis movable module 225, the first fixed plate 226 can be moved to the centralizing table 211 to remove the suction cup, and then moved to the processing table 12 to place the suction cup. It should be noted that the arrangement of the multiple first vacuum suction heads 227 is located in a one-to-one correspondence with the arrangement positions of the suction cups on the centralizing table 211, so that the suction cup conveying robot arm 22 can complete the driving of multiple suction cups at a time.

[0055] Preferably, the first X-axis moving module 223 includes an X-axis frame and an X-axis transmission member; the X-axis frame is slidably connected to the first beam 222 and can slide along the X-axis direction; the X-axis transmission member includes a fourth motor, a first rack and a first gear, the first rack is installed on the first beam 222, the fourth motor is installed on the X-axis frame, the first gear is installed on the output end of the fourth motor and engages with the first rack; the first Y-axis moving module 224 is fixedly connected to the X-axis frame.

[0056] The first Y-axis moving module 224 includes a Y-axis frame and a Y-axis transmission member; the Y-axis frame is slidably connected to the X-axis frame and can slide along the Y-axis direction; the Y-axis transmission member is used to drive the Y-axis frame to slide, and the first Z-axis moving module 225 is fixedly connected to the Y-axis frame.

[0057] The first Z-axis motion module 225 includes a Z-axis frame and a Z-axis transmission element. The Z-axis frame is slidably connected to the Y-axis frame and can slide along the Z-axis. The Z-axis transmission element is used to drive the Z-axis frame to slide. The first fixed plate 226 is fixedly connected to the Z-axis frame. Both the Y-axis transmission element and the Z-axis transmission element are transmission structures composed of a motor, rack, and gears. Their operating principles are similar to those of the X-axis transmission element and are not further described here.

[0058] As a preferred solution of this embodiment, a first suction cup positioning plate 2111 is fixed to the top of the centralizing platform 211. The first suction cup positioning plate 2111 is provided with a plurality of first suction cup positioning holes 2112. The positions of the first suction cup positioning holes 2112 on the first suction cup positioning plate 2111 correspond to the positions of the first vacuum heads 227 on the first fixing plate 226. In this embodiment, the first vacuum heads 227 are used to attract and drive the suction cups. However, the first Z-axis moving module 225 cannot ensure that the first vacuum heads 227 stop exactly when they contact the suction cups. If the first Z-axis moving module 225 moves downward excessively, the first vacuum heads 227 may squeeze the suction cups, causing the suction cups to adhere to the centralizing platform 211, making it difficult to drive the suction cups. To solve this problem, the first suction cup positioning plate 2111 is used in conjunction with the first vacuum suction head 227. When the SCARA robot 213 loads the material, the suction cup is placed in the first suction cup positioning hole 2112. When the suction cup conveying robot arm 22 takes the suction cup, the first Z-axis moving module 225 drives the first fixed plate 226 to contact the first suction cup positioning plate 2111. At this time, the first vacuum suction head 227 is in contact with the suction cup and will not excessively squeeze the suction cup, thereby ensuring that the suction cup conveying robot arm 22 can drive all the suction cups on the centralizing platform 211 at one time.

[0059] Furthermore, a first cylinder 228 is mounted on the first Z-axis moving module 225, and a first fixed plate 226 is disposed at the bottom of the first cylinder 228 and fixedly connected to the output shaft of the first cylinder 228. It should be noted that positional deviation is prone to occur during the movement of the Z-axis frame, i.e., it is not possible to ensure that the Z-axis frame moves to exactly contact the first suction cup positioning plate 2111. Moreover, when the Z-axis frame moves downward beyond a predetermined position along the Z-axis, i.e., after the first fixed plate 226 contacts the first suction cup positioning plate 2111, the Z-axis transmission component still tends to drive the Z-axis frame downward, which can easily damage the gears or racks in the Z-axis transmission component, thereby shortening the overall service life of the first Z-axis moving module 225. Therefore, in this embodiment, the design of the first cylinder 228 is adopted. Before the Z-axis frame descends, the output shaft of the first cylinder 228 first extends outward. When the Z-axis frame descends to the predetermined position, the first fixed plate 226 just contacts the processing table 12. If the Z-axis frame descends beyond the predetermined position, the processing table 12 generates a supporting force on the first fixed plate 226. The thrust of the first cylinder 228 is relatively small. Under the support force of the processing table 12, the output shaft of the first cylinder 228 is pushed back, and the Z-axis transmission member continues to drive the Z-axis frame downward without causing damage to the Z-axis transmission member. The above design ensures that the first fixed plate 226 moves to contact the first suction cup positioning plate 2111 while avoiding damage to the first Z-axis moving module 225, thereby extending the service life of the fully automatic hot melt equipment for producing foot pads.

[0060] Preferably, the first Z-axis moving module 225 and the first fixed plate 226 may also be connected via a spring.

[0061] Preferably, a first sensor is provided on the centralizing platform 211 at a position corresponding to each first suction cup positioning hole 2112. The first sensor can detect whether each first suction cup positioning hole 2112 is fully inserted with a suction cup, and can also detect whether the suction cup conveying robot arm 22 has missed any object.

[0062] As a preferred solution of this embodiment, a second suction cup positioning plate 121 is fixed to the top of the processing table 12. This second suction cup positioning plate 121 is provided with a plurality of second suction cup positioning holes 122. The positions of the second suction cup positioning holes 122 on the second suction cup positioning plate 121 correspond to the positions of the first suction cup positioning holes 2112 on the first suction cup positioning plate 2111. The second suction cup positioning holes 122 position the suction cups fed by the suction cup conveying robot 22 within the first suction cup positioning holes 2112. This prevents the suction cups from shifting when the foam pad conveying robot 32 places the foam pads over the suction cups. This design reduces the production of defective products.

[0063] As a preferred solution of this embodiment, the suction cup loading device 2 also includes a lifting ring suction cup placement mechanism 23; the lifting ring suction cup placement mechanism 23 includes a fixed frame 231, a first motor 232, a screw 233, a transmission block 234, a guide structure and a accommodating frame 237; the first motor 232 is installed on the fixed frame 231, the screw 233 is vertically arranged and rotatably connected to the fixed frame 231, and the first motor 232 is used to drive the screw 233 to rotate; the guide structure is installed on the fixed frame 231; the transmission block 234 is threadedly connected to the screw 233 and connected to the guide structure; the accommodating frame 237 is installed on the fixed frame 231, and a accommodating chamber formed by a vertical opening is provided in the accommodating frame 237. The accommodating frame 237 is provided with a strip-shaped opening on one side close to the screw 233, and the opening is connected to the accommodating chamber. The transmission block 234 passes through the opening and extends into the accommodating chamber. It should be noted that the ring suction cup is arranged at the edge of the foam pad, and the finished anti-slip mat can be hung by the ring portion of the ring suction cup, which is convenient for storage and transportation. The ring suction cup placement mechanism 23 involved in this embodiment realizes the automatic feeding of the ring suction cup. When in use, the ring suction cup is placed in the accommodating cavity, and the screw 233 is driven to rotate by the first motor 232. Under the action of the thread, the transmission block 234 is gradually lifted upward to lift the ring suction cup in the accommodating cavity upward. Further, in this embodiment, the ring suction cup placement mechanism 23 is arranged on the outside of the centralizing table 211, and the ring suction cup on the top of the accommodating cavity is picked up manually or by setting a material picking robot, and placed on the centralizing table 211 to be driven by the suction cup conveying robot arm 22. Preferably, the ring suction cup placement mechanism 23 can also be arranged on the outside of the processing table 12, and directly transported to the processing table 12 by manual labor or a robot.

[0064] Preferably, the guide structure includes a guide rail 235 and a slider 236 ; the guide rail 235 is parallel to the screw rod 233 and is mounted on the fixing frame 231 ; the slider 236 is slidably connected to the guide rail 235 ; and the transmission block 234 is fixedly connected to the slider 236 .

[0065] As a preferred embodiment of this embodiment, the foam pad placement mechanism 31 comprises a base plate 311, a lifting plate 312, a plurality of blocking rods 313, and a lifting control mechanism 314. The lifting plate 312 is positioned above the base plate 311. The blocking rods 313 are arranged in a ring around the outside of the lifting plate 312 and mounted on the base plate 311. The lifting control mechanism 314 is mounted on the base plate 311 and is used to drive the lifting plate 312 to move upward and downward. During use, a plurality of foam pads are stacked on the lifting plate 312, which is gradually raised by the lifting control mechanism 314 to facilitate the removal of the foam pads by the foam pad conveying robot 32.

[0066] Preferably, a second sensor is mounted on the top of any of the blocking rods 313, and the second sensor is connected to an alarm. The second sensor is used to detect the number of foam pads on the lifting plate 312. When the second sensor detects that all the foam pads on the lifting plate 312 have been removed, the second sensor activates the alarm to alert the staff to replenish the foam pads.

[0067] Preferably, a third sensor is mounted on the top of any of the blocking rods 313, and the third sensor is connected to an alarm. The thickness of the foam pad is approximately 5 mm. By setting a specific detection value for the third sensor, if the thickness of the output foam pad is greater than 6 mm, it is determined that the two foam pads are overlapping and are being taken out together by the foam pad conveying robot 32. At this time, the third sensor triggers an alarm to sound, reminding the staff to separate the overlapping foam pads.

[0068] As a preferred solution of this embodiment, the foam pad conveying robot 32 includes a second bracket; the second bracket includes a second crossbeam 322 and two second support columns 321, the second crossbeam 322 is arranged above the foam pad placement mechanism 31 and is installed on the two second support columns 321; a second X-direction moving module 323 is installed on the second crossbeam 322; a second Y-direction moving module 324 is provided on the second X-direction moving module 323; a second Z-direction moving module 325 is installed on the second Y-direction moving module 324; a second cylinder 326 is installed at the bottom of the second Z-direction moving module 325, and a second fixed plate 327 is provided below the second cylinder 326, the second fixed plate 327 is fixedly connected to the output shaft of the second cylinder 326, and a number of second vacuum suction heads 328 are installed on the second fixed plate 327. Specifically, the second X-axis movable module 323 can drive the second Y-axis movable module 324 to slide along the X-axis, the second Y-axis movable module 324 can drive the second Z-axis movable module 325 to slide along the Y-axis, and the second Z-axis movable module 325 can drive the second fixed plate 327 to move along the Z-axis. Thus, with the cooperation of the second X-axis movable module 323, the second Y-axis movable module 324, and the second Z-axis movable module 325, the second fixed plate 327 can move to the foam pad placement mechanism 31 to remove the foam pad, and then move to the processing table 12 to place the foam pad. The second cylinder 326 plays the same role in the foam pad conveying robot 32 as the first cylinder 228 plays in the suction cup conveying robot 22, so it will not be described in detail here.

[0069] The fully automatic hot-melt equipment for producing foot pads involved in the present invention solves the problem of low production efficiency due to the complex structure of the existing suction cup assembly equipment for anti-slip pads, which occupies too much space and requires manual loading of the anti-slip pads. After the suction cups are arranged, the mobile platform needs to be manually pushed onto the conveyor rack.

[0070] The above are only preferred embodiments of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
