Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] refer to Figures 1-2 An automatic hot stamping machine includes a machine base 1 and a conveyor belt 11 mounted on the machine base 1. The machine base 1 is provided with a frame 2, and the frame 2 is provided with a vertical lifting module 4 and a hot stamping module 3 for hot stamping the heel end of the insole. The vertical lifting module 4 is provided with a positioning unit 5, and the positioning unit 5 includes a horizontally extendable push plate assembly 52 and a clamping positioning mechanism 51.

[0032] The vertical lifting module 4 is used to drive the positioning unit 5 to lift.

[0033] The pusher assembly 52 is used to push the heel end of the insole into the clamping range of the clamping and positioning mechanism 51;

[0034] The clamping and positioning mechanism 51 is used to contact both sides of the insole and adjust the position of the insole on the conveyor belt 11.

[0035] It should be noted that when the insole is placed on the conveyor belt 11, the heel end of the insole is facing the positioning unit 5.

[0036] In this design, the insole is placed on the conveyor belt 11. When the conveyor belt 11 transports the insole to below the pusher assembly 52, it stops. Then, the vertical lifting module 4 drives the positioning unit 5 downward. The pusher assembly 52 then pushes the heel end of the insole, so that the heel end of the insole is pushed into the clamping range of the clamping and positioning mechanism 51. Then, the clamping and positioning mechanism 51 simultaneously contacts both sides of the insole to adjust the position of the insole on the conveyor belt 11. After the adjustment is completed, the clamping and positioning mechanism 51 resets, the pusher assembly 52 resets, and the vertical lifting module 4 resets. Then, the conveyor belt 11 works again to transport the heel end of the insole to below the hot stamping module 3 for trademark hot stamping.

[0037] In a preferred embodiment, the pusher assembly 52 remains in contact with the heel end of the insole throughout the process from pushing the heel end of the insole to the contact between the clamping and positioning mechanism 51 and the sides of the insole; in other embodiments, the pusher assembly 52 retracts and returns to its original position after pushing the heel end of the insole into the clamping range of the clamping and positioning mechanism 51.

[0038] Preferably, the vertical lifting module 4 includes a first mounting plate 41 disposed on one side of the frame 2, a first cylinder 42 disposed on the first mounting plate 41, and a fixing plate 43 disposed at the output end of the first cylinder 42, and the positioning unit 5 is disposed at the bottom of the fixing plate 43.

[0039] Furthermore, the positioning unit 5 is placed at the bottom of the fixed plate 43, and the fixed plate 43 is moved by the first cylinder 42, thereby driving the positioning unit 5 to rise and fall.

[0040] More preferably, the clamping and positioning mechanism 51 includes a mounting bracket 511 disposed at the bottom of the fixing plate 43, a motor 512 disposed on the mounting bracket 511, and a forward and reverse threaded screw 513;

[0041] The mounting frame 511 has a horizontally arranged sliding groove 514, in which two symmetrically arranged clamping components 515 are slidably connected. A threaded rod 513 is disposed in the sliding groove 514, and both ends of the threaded rod 513 are threadedly connected to the two clamping components 515 respectively. The output end of the motor 512 is connected to the threaded rod 513, and the motor 512 is used to drive the threaded rod 513 to rotate, so that the two clamping components 515 move closer to each other to contact and position the two sides of the heel end of the insole. The push plate assembly 52 is disposed on the mounting frame 511 and is located between the two clamping components 515.

[0042] Specifically, a slide groove 514 is provided on the mounting frame 511, and the clamping assembly 515 is slidably placed in the slide groove 514. When the push plate assembly 52 pushes the heel end of the insole into the range of the clamping assembly 515, the motor 512 drives the rotation of the positive and negative thread screw 513, thereby driving the two symmetrically arranged clamping assemblies 515 to move closer to each other, so as to contact the sides of the insole to adjust the position of the insole on the conveyor belt 11. After the position adjustment is completed, the motor 512 drives the positive and negative thread screw 513 to rotate in the opposite direction, so that the two clamping assemblies 515 move away from each other.

[0043] In this embodiment, the clamping assembly 515 includes a fixed arm 5151 and two first connecting plates 5152 disposed on the side of the fixed arm 5151 near the push plate assembly 52. ​​One end of the fixed arm 5151 is slidably connected in the slide groove 514 and threadedly connected to the positive and negative thread screws 513. The first connecting plate 5152 is threadedly connected with a threaded post 5153 for contacting the heel end of the insole.

[0044] Furthermore, one end of the fixed arm 5151 is slidably connected to the slide groove 514. When the motor 512 drives the positive and negative thread screws 513 to bring the fixed arms 5151 closer to each other, the threaded post 5153 threadedly connected to the first connecting plate 5152 will contact the heel end of the insole, thereby completing the clamping and positioning of the heel end of the insole.

[0045] Preferably, the pusher assembly 52 includes a second cylinder 521 disposed on the side of the mounting bracket 511, and a pusher 522 is provided at the output end of the second cylinder 521. The second cylinder 521 serves as a power source to drive the pusher 522 to extend or retract.

[0046] Preferably, it also includes multiple vertically arranged movable rods 6 and buffer blocks 9 set at both ends of the mounting frame 511; the movable rods 6 are movably inserted through the fixed plate 43, and one end of the movable rods 6 is connected to the mounting frame 511, and the other end is provided with a limiting block 61;

[0047] A spring 62 is fitted on the movable rod 6, and the spring 62 is located between the fixed plate 43 and the mounting bracket 511; when the first cylinder 42 drives the fixed plate 43 to move downward, the buffer block 9 first contacts the machine base 1 and then compresses the spring 62.

[0048] Specifically, to prevent the vertical clamping assembly 515 from pressing down on the conveyor belt 11 and affecting its position, or from causing the insole to shift and thus affecting the positioning effect, buffer blocks 9 are provided at both ends of the mounting frame 511. When the vertical lifting module 4 drives the clamping assembly 515 to descend, the buffer blocks 9 first contact the machine base 1. Since the movable rod 6 is movably connected to the fixed plate 43, the mounting frame 511 and the fixed plate 43 will move relative to each other and compress the spring 62, thereby preventing the clamping assembly 515 from pressing down on the conveyor belt 11.

[0049] Implicitly, buffer block 9 can be made of nylon.

[0050] More preferably, it also includes a storage unit 7 for storing insoles and a picking unit 8. The storage unit 7 is located at one end of the conveyor belt 11, and the picking unit 8 is arranged on the machine base 1. The picking unit 8 is used to absorb the insoles in the storage unit 7 and transfer the insoles to the conveyor belt 11.

[0051] Furthermore, by cooperating with the material handling unit 8 and the material storage unit 7, the material handling unit 8 can adsorb and transfer the insoles in the material storage unit 7, thereby improving the conveying efficiency of the insoles.

[0052] Preferably, the storage unit 7 includes a drive mechanism 75 and a support plate 72 connected to the drive mechanism 75. The support plate 72 is provided with a storage trough 76 for storing insoles. The drive mechanism 75 is used to drive the support plate 72 upward so that the material retrieval unit 8 can adsorb the insoles in the storage trough 76.

[0053] The driving mechanism 75 includes a base 71, a vertically arranged guide rod 73 and a threaded rod 74. One end of the guide rod 73 is connected to the base 71, and the other end passes through the support plate 72 and is movably connected to the support plate 72. The base 71 is provided with a driving mechanism 75 for driving the threaded rod 74 to rotate. One end of the threaded rod 74 is connected to the driving mechanism 75, and the other end passes through the support plate 72 and is threadedly connected to the support plate 72.

[0054] Specifically, the stacked insoles are placed in the storage trough 76, and when placing the insoles, the heel end of the insoles is placed towards the positioning component; after the picking unit 8 takes an insole from the storage trough 76, the threaded rod 74 is driven to rotate by the drive mechanism 75, and the guide rod 73 is used to drive the support plate 72 to move upward, so that the picking unit 8 can better adsorb the insoles in the storage trough 76.

[0055] In practical use, the drive mechanism 75 can use a combination of a motor and a bevel gear to drive the threaded rod 74 to rotate.

[0056] Preferably, the material handling unit 8 includes a fixed frame 81 mounted on the machine base 1 and a linear module 82 mounted on the fixed frame 81. The linear module 82 is provided with a slider 83, and the slider 83 is provided with a third cylinder 84. The output end of the third cylinder 84 is provided with a second connecting plate 86, and the bottom of the second connecting plate 86 is provided with a suction cup 85 corresponding to the storage tank 76. The third cylinder 84 is used to drive the suction cup 85 downward to adsorb the insole in the storage tank 76. The linear module 82 is used to drive the suction cup 85 to reciprocate between the storage tank 76 and the conveyor belt 11.

[0057] The linear module 422 has been disclosed in Chinese patent CN217463103U, so the structure of the linear module 422 will not be described in detail in this embodiment.

[0058] The suction cup 85 can be connected to an external negative pressure device to create a vacuum to adsorb the insole.

[0059] Furthermore, when the insole in the storage tank 76 needs to be transferred to the conveyor belt 11, the third cylinder 84 drives the second connecting plate 86 downward, which in turn drives the suction cup 85 downward, thereby adsorbing the insole in the storage tank 76. After adsorption, the third cylinder 84 resets, and the linear module 82 moves the suction cup 85 above the conveyor belt 11 by driving the slider 83. Then, the third cylinder 84 drives the suction cup 85 downward again and releases the insole so that it is placed on the conveyor belt 11. After the insole is placed on the conveyor belt 11, the third cylinder 84 drives the suction cup 85 to reset, and the linear module 82 drives the suction cup 85 to move back above the storage tank 76 to adsorb and transfer the next insole.

[0060] Preferably, the number of the material storage tank 76, suction cup 85, push plate assembly 52, clamping and positioning mechanism 51 and hot stamping module 3 are all two.

[0061] Specifically, when hot stamping the insole trademark, the left and right insoles can be placed in the storage tank 76 respectively. Then, the insoles are removed from the storage tank 76 by the suction cup 85 and placed on the conveyor belt 11. The conveyor belt 11 transports the two insoles to the positioning unit 5. After that, the position of the insoles is adjusted by the push plate assembly 52 and the clamping positioning mechanism 51, and then transported by the conveyor belt 11 to the hot stamping module 3 for trademark hot stamping.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
