Description

Technical Field

[0001] This utility model belongs to the field of marking equipment technology, and in particular relates to an automated button marking machine. Background Technology

[0002] Buttons are widely used in various clothing, shoes, hats and bags as fastening tools. People also use marking equipment to stamp the face of semi-finished buttons to form various patterns or text on the face, which serves as decoration or identification.

[0003] Traditional button marking equipment mainly consists of a positioning mechanism with a mold and a stamping mechanism with a pressure column. The positioning mechanism has an operating station for placing buttons, and the mold is set at the operating station corresponding to the button face. The stamping mechanism drives the pressure column into the operating station and squeezes the inside of the button so that the button face contacts the mold to form a pattern. After marking is completed, the user needs to remove the button with the pattern from the operating station and then place a new semi-finished button in the operating station for further processing. The whole process requires manual operation, which is time-consuming and labor-intensive, and seriously affects processing efficiency. Therefore, it is necessary to design an automated button marking machine to solve this problem. Utility Model Content

The positioning mechanism is mounted on the machine body and has a loading station, a buffer station, and an operating station, with a mold installed in the operating station. The stamping mechanism includes a pressure column and a first driving unit. The pressure column is positioned corresponding to the buffer station and the operating station, and the first driving unit is mounted on the machine body and drivenly connected to the pressure column. The feeding mechanism is used to feed semi-finished buttons to the loading station. The pushing mechanism includes a first push rod and a second push rod. The machine includes a push rod and a second drive unit. The first push rod is positioned corresponding to the loading station and the buffer station, and the second push rod is positioned corresponding to the operating station. The second drive unit is mounted on the machine body and is drivenly connected to the first push rod and the second push rod. The first push rod can push the button at the loading station to the buffer station, and the pressure rod can push the button at the buffer station into the operating station, causing the button's faceplate to contact the mold for marking. The second push rod can push the marked button out of the operating station.

[0006] Preferably, the positioning mechanism includes a base, on which a first pushing groove and a second pushing groove are provided. The loading station is formed in the first pushing groove, the buffer station is formed at the end of the first pushing groove, and the operating station is formed in the second pushing groove. The feeding mechanism communicates with the first pushing groove to deliver buttons to the loading station. The first push rod is slidably connected to the first pushing groove to push the buttons at the loading station to the buffer station along the first pushing groove. The second push rod is slidably connected to the second pushing groove to push the marked buttons out from the operating station along the second pushing groove.

[0007] Preferably, the second drive unit is synchronously driven and connected to the first push rod and the second push rod, and the length of the second push rod is greater than that of the first push rod; when the first push rod moves along the first push groove to push the button at the loading station to the buffer station, the second push rod synchronously pushes the marked button out of the operating station along the second push groove.

[0008] Preferably, the positioning mechanism further includes a first abutment, a second abutment, a first elastic element, and a second elastic element. The base is also provided with a first sliding groove and a second sliding groove communicating with the inside and outside of the first push groove.

The first elastic element is disposed in the base and abuts against the base and the first abutment. The second elastic element is disposed in the base and abuts against the base and the second abutment. During the process of the first push rod driving the button to enter the buffer station along the first push groove, the button simultaneously squeezes the first abutment and the second abutment to deform and store energy. After the button enters the buffer station, the first elastic element and the second elastic element release energy and recover, simultaneously driving the first abutment and the second abutment to reset, thereby abutting and restricting the button in the buffer station for retention.

The base and the second limiting rod are connected; wherein, during the process of the pressure column driving the button from the buffer station into the second pusher groove, the button simultaneously squeezes the first and second limiting rod ends, so that the third and fourth elastic elements deform and store energy. After the button disengages from the first and second limiting rods, the third and fourth elastic elements release energy and recover, simultaneously driving the first and second limiting rod ends to reset, thereby preventing the button from following the pressure column back to the buffer station for unloading.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application.

[0019] See appendix Figure 1 -Appendix Figure 8An automated button marking machine includes a body 1, a positioning mechanism 2, a stamping mechanism 3, a feeding mechanism 4, and a pushing mechanism 5. The positioning mechanism 2 is mounted on the body 1 and has a feeding station 201, a buffer station 202, and an operating station 203, with a mold 204 installed in the operating station 203. The stamping mechanism 3 includes a pressure column 31 and a first drive unit 32. The pressure column 31 is set corresponding to the buffer station 202 and the operating station 203, and the first drive unit 32 is mounted on the body 1 and drivenly connected to the pressure column 31. The feeding mechanism 4 is used to feed semi-finished buttons to the feeding station 201. The pushing mechanism 5 includes a first push rod 5. 1. A second push rod 52 and a second drive unit 53. The first push rod 51 is set to the loading station 201 and the buffer station 202, and the second push rod 52 is set to the operating station 203. The second drive unit 53 is installed on the machine body 1 and is drivenly connected to the first push rod 51 and the second push rod 52. The first push rod 51 can push the button at the loading station 201 to the buffer station 202, and the pressure column 31 can push the button at the buffer station 202 into the operating station 203, so that the button's faceplate contacts the mold 204 for marking. The second push rod 52 can push the marked button out of the operating station 203.

[0020] Specifically, in use, the feeding mechanism 4 first provides buttons to the loading station 201 (the buttons can be unplated raw materials or semi-finished products that have undergone electroplating). Then, the second drive unit 53 is activated to drive the first push rod 51 to move and push the buttons at the loading station 201 to the buffer station 202 so that the top of the buttons aligns with the pressure post 31. Then, the first drive unit 32 is activated to drive the pressure rod to move to the operating station 203 so that the buttons left at the buffer station 202 are pushed into the operating station 203 and the top of the buttons contacts the mold 204 for marking. After marking is completed, the first drive unit 32 drives the pressure rod away from the operating station 203 and returns it to its original position. The second drive unit 53 is activated to drive the second push rod 52 to move and push the marked buttons at the operating station 203 out to the outside.

[0021] In summary, this utility model, by setting up a positioning mechanism 2 with a feeding station 201, a buffer station 202, and an operating station 203 to work in conjunction with the feeding mechanism, the pressure column 31, the first push rod 51, and the second push rod 52, enables the conveying, marking, and discharging of buttons to be carried out in a centralized manner. Compared with the manual handling of buttons, this solution achieves automated button handling, saving time and effort and effectively improving work efficiency.

[0022] See appendix Figure 5 -Appendix Figure 9The positioning mechanism 2 includes a base 20, on which a first pusher groove 205 and a second pusher groove 206 are provided. The loading station 201 is formed in the first pusher groove 205, the buffer station 202 is formed at the end of the first pusher groove 205, and the operating station 203 is formed in the second pusher groove 206. The feeding mechanism 4 is connected to the first pusher groove 205 to deliver buttons to the loading station 201. The first push rod 51 is slidably connected to the first pusher groove 205 to push the buttons at the loading station 201 to the buffer station 202 along the first pusher groove 205. The second push rod 52 is slidably connected to the second pusher groove 206 to push the marked buttons out from the operating station 203 along the second pusher groove 206.

[0023] Specifically, in use, the feeding mechanism 4 first delivers buttons to the loading station 201 located in the first pushing groove 205. Then, the second drive unit 53 is activated to drive the first push rod 51 to move along the first pushing groove 205, so as to push the buttons at the loading station 201 to the buffer station 202 for placement. Then, the first drive unit 32 is activated to drive the pressure rod to move towards the operating station 203, so as to push the buttons placed at the buffer station 202 into the operating station 203. The button's faceplate contacts the mold 204 for marking. After marking, the second drive unit 53 is activated to drive the second push rod 52 to move along the second push groove 206, thus pushing the marked button out of the operating station 203. The design of the first push groove 205 and the second push groove 206 can respectively restrict the movement direction of the first push rod 51 and the second push rod 52, and improve the movement stability of the first push rod 51 and the second push rod 52, thereby ensuring more stable material feeding.

[0024] See appendix Figure 5 -Appendix Figure 9 In actual production, it is usually assumed that the second drive unit 53 alternately drives the first push rod 51 and the second push rod 52 to move independently, that is, the feeding and discharging of buttons are carried out independently. In this case, there is no need to limit the length of the first push rod 51 and the second push rod 52. However, in actual use, it has been found that this driving method will cause a time difference between feeding and discharging, which will affect work efficiency. To solve this problem, in this embodiment, the second drive unit 53 is synchronously driven and connected with the first push rod 51 and the second push rod 52, and the length of the second push rod 52 is greater than that of the first push rod 51.

[0025] Specifically, under normal circumstances, the end of the first push rod 51 is located in front of the loading station 201, and the end of the second push rod 52 is located in front of the operating station 203. When the second drive unit 53 is activated to synchronously drive the first push rod 51 and the second push rod 52 to move along the first push groove 205 and the second push groove 206 respectively, the first push rod 51 will push the button from the loading station 201 to the buffer station 202, while the second push rod 52 will simultaneously push the marked button out from the operating station 203. Therefore, the above structural design allows the button loading and unloading to be carried out synchronously, thereby eliminating the time difference and improving work efficiency.

[0026] See appendix Figure 7 -Appendix Figure 15 In some embodiments, the buffer station 202 is designed as a through-hole structure that is wider at the top and narrower at the bottom (not shown in the figure), and the minimum diameter of the through-hole is designed to be slightly smaller than the diameter of the button, so that the button can be properly placed in the buffer station 202. When the pressure applied by the pressing column 31 can overcome the friction between the button and the through-hole, the button can be pressed into the operating station 203. Although this design is simple in structure, it is easy to damage the button. To solve this problem, in this embodiment, the positioning mechanism 2 also includes a first abutment 21, a second abutment 22, a first elastic element 23, and a second elastic element 24. The base 20 is also provided with a first sliding groove 2051 and a second sliding groove 2052 that connect the inside and outside of the first pushing groove 205; the first abutment 21 is slidably connected to the first sliding groove 2051, and the second abutment 22 is slidably connected to the second sliding groove 2052, and the head ends of the first abutment 21 and the second abutment 22 are both placed in the first pushing groove 205 and correspond to the buffer station 202; the first elastic member 23 is disposed in the base 20 and abuts against the base 20 and the first abutment 21, and the second elastic member 24 is disposed in the base 20 and abuts against the base 20 and the second abutment 22.

[0027] Specifically, during the process of the first push rod 51 driving the button to enter the buffer station 202 along the first push groove 205, the button simultaneously squeezes the head end of the first abutment 21 and the head end of the second abutment 22, so that the first abutment 21 and the second abutment 22 move away from each other, and drive the first elastic element 23 and the second elastic element 24 to deform and store energy; after the button enters the buffer station 202, the first elastic element 23 and the second elastic element 24 release energy and recover, and simultaneously drive the head end of the first abutment 21 and the head end of the second abutment 22 to reset, so as to abut and restrict the button within the buffer station 202 for retention.

[0028] When the pressure column 31 moves the button toward the operating station 203, the button will again synchronously press the first end of the first abutment 21 and the first end of the second abutment 22 to overcome the elastic potential energy, so that the first abutment 21 and the second abutment 22 move away from each other, ensuring that the button can smoothly follow the pressure column 31 into the operating station 203 for marking; after the pressure column 31 returns to its original position, the first abutment 21 and the second abutment 22 reset again under the action of the first elastic element 23 and the second elastic element 24.

[0029] In summary, the combined use of the first abutment 21, the second abutment 22, the first elastic element 23, and the second elastic element 24 can keep the button in the buffer station 202 without damaging it. However, the design cost of this structure is relatively high. Therefore, in the actual production process, manufacturers can choose to set the corresponding structure according to their needs. This utility model does not impose any restrictions on this.

[0030] See appendix Figure 7 -Appendix Figure 15 The first abutment 21 and the second abutment 22 are respectively provided with a first mounting groove 210 and a second mounting groove 220. The base 20 is provided with a first stop 210d extending into the first mounting groove 210 and a second stop 220d extending into the second mounting groove 220. The first elastic member 23 is disposed in the first mounting groove 210 and abuts against the first stop 210d and the side wall of the first mounting groove 210. The second elastic member 24 is disposed in the second mounting groove 220 and abuts against the second stop 220d and the side wall of the second mounting groove 220. This design can reserve installation positions for the first elastic member 23 and the second elastic member 24, and make the first elastic member 23 and the second elastic member 24 easier to deform and recover, reducing the possibility of the first abutment 21 and the second abutment 22 getting stuck during movement, and also making the structure more compact.

[0031] See appendix Figure 7 -Appendix Figure 15 The tail ends of the first abutment 21 and the second abutment 22 are respectively threaded with a first bolt 211 and a second bolt 221. The end of the first bolt 211 extends into the first mounting groove 210 and abuts against the first stop 210d. The end of the second bolt 221 extends into the second mounting groove 220 and abuts against the second stop 220d.

[0032] Specifically, during use, the distance between the first end of the first abutment 21 and the second end of the second abutment 22 can be adjusted by simultaneously tightening the first bolt 211 and the second bolt 221, thereby adapting to and restricting buttons of various diameters within the buffer station 202, thus improving applicability.

[0033] It should be noted that when the first bolt 211 and the second bolt 221 are tightened to minimize the distance between the first end of the first abutment 21 and the first end of the second abutment 22, and neither the first end of the first abutment 21 nor the first end of the second abutment 22 is in contact with the button, the first elastic element 23 and the second elastic element 24 must maintain slight deformation to prevent the first abutment 21 and the second abutment 22 from losing their reset function, and to ensure that the first end of the first abutment 21 and the first end of the second abutment 22 can properly abut against the button with the smallest diameter on the market. On the other hand, when the diameter of the selected button changes, a mold 204 of the corresponding size also needs to be installed to fit the button's cover.

[0034] See appendix Figure 7 -Appendix Figure 15 Considering that in actual use, some buttons may adhere to the pressure column 31 after marking and reset with the pressure column 31, which will leave the operating station 203 empty and cause the second push rod 52 to fail to push out the material normally; to solve this problem, in this utility model, the positioning mechanism 2 also includes a first limiting rod 25, a second limiting rod 26, a third elastic element 27 and a fourth elastic element 28, and the base 20 is also provided with a third sliding groove 2061 and a fourth sliding groove 2062 that connect the inside and outside of the second pushing groove 206; the first limiting rod 25 is slidably connected to the third sliding groove 2061, the second limiting rod 26 is slidably connected to the fourth sliding groove 2062, and the head ends of the first limiting rod 25 and the second limiting rod 26 are both placed in the second pushing groove 206 and correspond to the operating station 203; the third elastic element 27 is set in the base 20 and abuts against the base 20 and the first limiting rod 25, and the fourth elastic element 28 is set in the base 20 and abuts against the base 20 and the second limiting rod 26.

[0035] Specifically, during the process of the pressure column 31 driving the button from the buffer station 202 into the second pusher trough 206, the button simultaneously squeezes the first end of the first limiting rod 25 and the first end of the second limiting rod 26, causing the third elastic element 27 and the fourth elastic element 28 to deform and store energy; after the button disengages from the first limiting rod 25 and the second limiting rod 26 and enters the operating station 203, the third elastic element 27 and the fourth elastic element 28 release energy and recover, simultaneously driving the first end of the first limiting rod 25 and the first end of the second limiting rod 26 to reset and abut against the side wall of the pressure column 31. When the first drive unit 32 drives the pressure bar away from the operating station 203 and resets, the first end of the first limit rod 25 and the first end of the second limit rod 26 will abut against the top side of the marked button to prevent the button from following the pressure bar back to the buffer station 202 for unloading, ensuring that the marked button remains in the operating station 203 for the second push rod 52 to push it out to the outside; and when the pressure bar is fully reset, the third elastic element 27 and the fourth elastic element 28 will drive the first end of the first limit rod 25 and the first end of the second limit rod 26 to be fully reset.

[0036] In summary, the combined use of the first limiting rod 25, the second limiting rod 26, the third elastic element 27, and the fourth elastic element 28 can remove the marked buttons, preventing the buttons from resetting with the pressure column 31 and entering the buffer station 202, thus ensuring that the second push rod 52 can properly push out the marked buttons.

[0037] See appendix Figure 7 -Appendix Figure 15 The first limiting rod 25 and the second limiting rod 26 are respectively provided with a third mounting groove 250 and a fourth mounting groove 260. The base 20 is provided with a third stop 250d extending into the third mounting groove 250 and a fourth stop 260d extending into the fourth mounting groove 260. The third elastic member 27 is disposed in the third mounting groove 250 and abuts against the third stop 250d and the side wall of the third mounting groove 250. The fourth elastic member 28 is disposed in the fourth mounting groove 260 and abuts against the fourth stop 260d and the side wall of the fourth mounting groove 260. This design can reserve installation positions for the third elastic member 27 and the fourth elastic member 28, and make the third elastic member 27 and the fourth elastic member 28 easier to deform and recover, reducing the possibility of the first limiting rod 25 and the second limiting rod 26 getting stuck during movement, and also making the structure more compact.

[0038] It should be noted that the first elastic element 23, the second elastic element 24, the third elastic element 27 and the fourth elastic element 28 can be springs, elastic rubber columns and other parts. Since there are many types of related parts, this utility model does not limit them.

[0039] See appendix Figure 7 -Appendix Figure 15 The button is circular. The first abutment 21 and the second abutment 22 are respectively provided with a first semi-conical opening 21k and a second semi-conical opening 22k. The first semi-conical opening 21k and the second semi-conical opening 22k enclose each other to form an inverted cone-shaped retention space. The diameter of the retention space gradually decreases towards the operating position 203, and the minimum diameter of the retention space is smaller than the diameter of the button. The first limiting rod 25 and the second limiting rod 26 are respectively provided with a third semi-conical opening 25k and a fourth semi-conical opening 26k. The third semi-conical opening 25k and the fourth semi-conical opening 26k enclose each other to form an inverted cone-shaped expansion space. The diameter of the expansion space gradually decreases towards the operating position 203, and the minimum diameter of the expansion space is smaller than the diameter of the button.

[0040] Specifically, the diameter of the inverted conical retention space varies at different points, thus it can accommodate buttons of various diameters. At the same time, it can reduce the friction between the button and the first stop bar 21 and the second stop bar 22, making it easier for the pressure column 31 to drive the button out of the retention space and into the second pusher groove 206. Similarly, the diameter of the inverted conical expansion space also varies at different points, thus it can accommodate buttons of various diameters. At the same time, it can reduce the friction between the button and the first limit bar 25 and the second limit bar 26, making it easier for the pressure column 31 to drive the button out of the expansion space and into the operating station 203 for marking.

[0041] In summary, the above structural design can further improve applicability and avoid damage caused by rigid collisions between the button and the first stop bar 21, the second stop bar 22, the first limit bar 25, and the second limit bar 26, thereby improving the yield rate.

[0042] See appendix Figure 7 -Appendix Figure 15 The base 20 is also provided with a notch 207 on the side of the first pusher groove 205. The notch 207 is connected to the first pusher groove 205 and is set in accordance with the feeding station 201. The feeding mechanism 4 includes a vibrating plate 41 and a conveying pipe 42. The vibrating plate 41 is installed on the machine body 1 or is set independently outside the machine body 1. The conveying pipe 42 is connected to the vibrating plate 41 and the notch 207.

[0043] Specifically, in use, the vibratory feeder 41 vibrates the buttons into the conveying pipe 42, and the conveying pipe 42 then conveys the buttons one by one to the loading station 201 in the first pusher trough 205 through the notch 207, thereby completing the automated loading of the buttons; wherein, the notch 207 is set so that the buttons can enter the loading station 201 from the side of the first pusher trough 205, thereby reducing the possibility of vibration of the buttons during the conveying process and ensuring the stability of the conveying.

[0044] It should be noted that the vibratory feeder 41 is an existing product and comes in various types. Therefore, its specific structure and working principle will not be described in detail in this utility model, nor will its model number be limited.

[0045] See appendix Figure 5 -Appendix Figure 7 The base 20 is also provided with a cover plate 208, which covers the top side of the first push groove 205 and the notch 207. The cover plate 208 is provided with an observation port 209 corresponding to the first push groove 205 and the notch 207. The diameter of the observation port 209 is smaller than the diameter of the button.

[0046] Specifically, the design of the cover plate 208 can prevent the buttons from jumping and falling off above the first pusher trough 205 and the notch 207 during the conveying process, thus improving the stability of the conveying. The design of the observation port 209 makes it convenient for users to observe whether the buttons can normally enter the first pusher trough 205 and the loading station 201 through the notch 207, ensuring that users can deal with the situation in time if the buttons are stacked or stuck at the loading station 201.

[0047] See appendix Figure 2 -Appendix Figure 4 The present invention also includes a material box 6, which is installed on the machine body 1 and located next to the base 20. The material box 6 is provided with a hopper 60 that connects to the end of the second push groove 206. After the marked buttons are pushed out of the second push groove 206 by the second push rod 52, they will enter the material box 6 through the hopper 60 for storage, so as to facilitate users to collect and use them in a unified manner and improve the convenience of use.

[0048] See appendix Figure 1 -Appendix Figure 8 The first drive unit 32 adopts hydraulic drive components such as hydraulic pumps and hydraulic cylinders, pneumatic drive components such as air pumps and pneumatic cylinders, or electric drive components such as lead screw electric cylinders; the second drive unit 53 adopts lead screw motors or cylinders; since there are various types of related components with moving strokes, and they are relatively conventional in the mechanical field, this utility model will not describe or limit them in detail.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
