[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0050] In the button production process, a pin 7 and a panel 8 need to be assembled together to form a button unit 9, and then the two are welded together by a welding system 200 to form a fixed button part. Fig.10 As shown, Fig.10 It is a schematic diagram of the structure of the tube pin 7 and the structural diagram of the panel 8, wherein the tube pin 7 has a tube body 71 and a circular piece 72 coupled to the bottom of the tube body 71; the panel 8 has a groove 81 suitable for receiving the circular piece 72, and a wall portion extending upward from the bottom wall of the groove 81 is arranged on the outer side of the groove 81; during welding, the wall portion is melted and pressed toward the inside of the groove 81 through the welding system 200 to fix the tube pin 7 to the panel 8.

[0051] However, the existing button production equipment has the following problems during the production process: when assembling the panel 8 and the pin 7, one of the two is often not delivered in place, resulting in only the panel 8 without the pin 7, or only the pin 7 without the panel 8, which increases the defective rate of button processing and thus increases the production cost of buttons. In order to solve the above problems, the utility model provides an automated button production equipment, which can remove the button unit 9 with the above defects from the assembly system 100 during the processing process, and the equipment has a high degree of automation and can complete the above operations without stopping the machine, thereby improving the efficiency and quality of button production.

[0052] See also Figures 1 to 9 As shown, the button automated production equipment includes an assembly system 100 and a welding system 200. The assembly system 100 is configured to assemble the pins 7 onto the panel 8 to form a button unit 9, and transport the button unit 9 to the welding system 200 for welding. The assembly system 100 includes a frame 6 and a turntable assembly 110. The turntable assembly 110 is configured to be able to position and transport the panel 8 and the pins 7, and during the transportation process, the pins 7 and the panel 8 are assembled together to form the button unit 9.

[0053] See also Figure 1-7 As shown, the assembly system 100 further includes a panel assembly station F1 for assembling the panel 8 onto the turntable assembly 110, and a pin assembly station F2 for assembling the pins 7 onto the panel 8. The turntable assembly 110 includes a first turntable 111, on which a plurality of material receiving structures are arranged along its circumferential direction. The material receiving structures will sequentially pass through the panel assembly station F1 and the pin assembly station F2 during the rotation of the first turntable 111, and then receive the panel 8 and the pins 7 respectively, and assemble the panel 8 and the pins 7 together to form a button unit 9, and then the button unit 9 is transported to the welding system 200, and the two are welded together by the welding system 200. In order to prevent the button unit 9 from being thrown out of the first turntable 111 during the conveying process, a barrier 112 is provided on the outer side of the first turntable 111, and the barrier 112 is fixed to the frame 6, and the inner wall of the barrier 112 is close to the peripheral side wall of the first turntable 111, and the height of its upper edge is higher than the height of the material receiving structure. In addition, the barrier 112 is provided with corresponding notches at the panel assembly station F1, the pin assembly station F2, the waste discharge station F3 and the transfer station F4, so that the panel 8 and the pin 7 can be received or removed at the corresponding station. The transfer station F4 is configured to transfer the assembled button unit 9 to the position of the welding system 200.

[0054] In order to screen out the situation where there is no panel 8 in the material receiving structure, the material receiving structure includes a material receiving groove 111a and a material drop hole 111b, wherein the material drop hole 111b is arranged below the material receiving groove 111a and communicates with the material receiving groove 111a, and the material drop hole 111b is arranged so that when there is no panel 8 in the material receiving groove 111a, the pin 7 can fall through the material drop hole 111b. Furthermore, the center line of the material drop hole 111b coincides with the center line of the material receiving groove 111a, and the diameter of the material drop hole 111b is between the diameter D1 of the pin 7 and the diameter D2 of the panel 8, see for details. Fig.11 As shown, when the panel 8 falls into the receiving trough 111a, it will not fall out of the drop hole 111b. However, if there is no panel 8 to be received in the receiving trough 111a, the pin 7 can fall directly from the drop hole 111b, thereby avoiding the situation where only the pin 7 enters the welding system 200. The structure is simple and can effectively discharge the pin 7 that is not assembled with the panel 8. There is no need to set up a separate removal device for discharging the pin 7, thereby reducing the production cost of the equipment.

[0055] In some embodiments, the turntable assembly 110 includes a first turntable 111, which is rotatably arranged on the frame 6. In this embodiment, the first turntable 111 includes a fixed shaft seat, a movable shaft seat, and an upper plate body, a positioning plate, and a lower plate body stacked in sequence from top to bottom, wherein the fixed shaft seat is fixedly connected to the frame 6, the movable shaft seat is installed in the fixed shaft seat by means of a bearing, the lower plate body is fixedly connected to the movable shaft seat, the circumferential outer edge of the lower plate body is provided with the drop hole 111b, the circumferential outer edge of the positioning plate is provided with the receiving groove 111a, and the circumferential outer edge of the upper plate body has a material for positioning The positioning hole on the pin 7, the center lines of the positioning hole, the material receiving groove 111a and the blanking hole 111b are in the same line, and the positioning hole can guide the pin 7 to fall accurately on the center of the panel 8, that is, fall on the center of the blanking hole 111b, so that the panel 8 will fall directly from the blanking hole 111b without being stuck in the blanking hole 111b. In addition, the outer edge of the upper disk can partially cover the top of the material receiving groove 111a, so that the panel 8 can be placed more firmly in the material receiving groove 111a. Of course, the use of this assembled structural design reduces the overall processing difficulty of the parts, and in the event of damage, only the corresponding parts need to be replaced, reducing maintenance costs.

[0056] In addition, in order to solve the problem that there is only panel 8 but no pins 7 in the receiving trough 111a, the assembly system 100 also includes a waste discharge mechanism 120, which is suitable for moving the panel 8 without pins 7 out of the turntable assembly 110 at a waste discharge station F3 to prevent the panel 8 from entering the welding system 200; wherein the waste discharge mechanism 120 includes a pin positioning device 121 and a panel removing device 122, the pin positioning device 121 is configured to be movable between a first position and a second position, and the panel removing device 122 is configured to enable the panel 8 to be moved out of the turntable assembly 110; at the waste discharge station F3, the pin positioning device 121 moves to the second position, and the second position is configured so that the pin positioning device 121 can cooperate with the pins 7 to limit the panel 8 assembled with the pins 7 from being moved out of the turntable assembly 110, but allows the panel 8 without the pins 7 to be moved out of the turntable assembly 110.

[0057] By adopting the above structure, the panel 8 lacking the pin 7 can be moved out of the first turntable 111. Specifically, the pin positioning device 121 can move up and down between the first position and the second position, wherein the first position is located above the second position. When the first turntable 111 rotates to the panel assembly station F1 and the pin assembly station F2, the pin positioning device 121 is located at the first position away from the pin 7; when the first turntable 111 rotates to the waste discharge station F3, the pin positioning device 121 will be moved from the first position to the second position. Move downward to the second position, and fix the button unit 9 by combining with the pin 7, thereby limiting the panel 8 assembled with the pin 7 from being moved out of the turntable assembly 110 by the panel removal device 122, but allowing the panel 8 not assembled with the pin 7 to be moved out of the turntable assembly 110 by the panel removal device 122; when the pin positioning device 121 leaves the waste discharge station F3, the pin positioning device 121 will move upward from the second position to the first position and away from the pin 7, thereby not affecting the button unit 9 being transferred to the welding system 200.

[0058] The waste discharge mechanism 120 is attached to the first rotating disk 111, and one waste discharge mechanism 120 is correspondingly disposed at any of the material receiving structures. Figure 5-7 As shown, the pin positioning device 121 includes a positioning member 1213, a transmission member 1212, a first actuating member 1211 and an elastic member 1214; wherein the positioning member 1213 can be inserted into the pin hole 7; the transmission member 1212 is combined with the positioning member 1213 and can be linked with the positioning member 1213; the first actuating member 1211 can actuate the positioning member 1213 to move from the first position to the second position through the transmission member 1212; and the elastic member 1214 is configured to apply force to the transmission member 1212 in the direction in which the positioning member 1213 moves toward the second position. Figure 5 As shown, the first actuator 1211 is arranged on the frame 6, and has a retaining surface, and the retaining surface is configured to retain the positioning member 1213 at the first position at the panel assembly station F1 and the pin assembly station F2. It also has an actuating surface that is concave relative to the retaining surface, and the actuating surface is configured to enable the positioning member 1213 to move from the first position to the second position at the waste discharge station F3. Through the combination of the retaining surface and the actuating surface, the transmission member 1212 can drive the positioning member 1213 to move up and down between the first position and the second position.

[0059] Furthermore, the first turntable 111 is provided with a through slot 111c and a mounting frame arranged in the through slot 111c, the transmission member 1212 is passed through and slidably arranged in the mounting frame, the upper end of the transmission member 1212 is connected to the positioning member 1213, and the positioning member 1213 is located above the receiving slot 111a, and the lower end of the transmission member 1212 has a first roller 1215 that can rotatably abut against the first actuating member 1211, and the first actuating member 1212 is provided with a first roller 1215 that can rotatably abut against the first actuating member 1211. 11 is configured as a cylindrical cam, the retaining surface and the actuating surface are arranged around the cylindrical cam, the elastic member 1214 is a spring, and the spring is sleeved on the transmission member 1212. When the transmission member 1212 rotates following the first turntable 111, the spring can always apply an elastic force to the transmission member 1212, so that the first roller 1215 is always in contact with the cylindrical cam and rolls along the retaining surface and the actuating surface, so that the transmission member 1212 and the positioning member 1213 move up and down between the first position and the second position. When the first turntable 111 rotates, the transmission member 1212 and the positioning member 1213 are driven to rotate with the first turntable 111. When the first roller 1215 rolls on the holding surface of the first actuator 1211, the positioning member 1213 can be kept at the first position. At the first position, there is a space between the positioning member 1213 and the first turntable 111, so as to assemble the panel 8 at the panel assembly station F1, assemble the pins 7 at the pin assembly station F2, and transfer the button unit 9 at the transfer station F4. When the first turntable 111 rotates to the discharge station, the first roller 1215 rolls from the retaining surface to the actuating surface, thereby driving the positioning member 1213 to move from the first position to the second position. At the second position, the positioning member 1213 can be inserted into the hole of the pin 7, thereby fixing the button unit 9 on the first turntable 111, so that the panel removal device 122 can move out of the panel 8. When the first turntable 111 rotates the waste discharge station F3 to the transfer station F4, the positioning member 1213 will move from the second position to the first position, and this cycle will repeat.

[0060] Preferably, the positioning member 1213 can also be constructed as other components that can press the pin 7, which can be a pressure plate, a cylindrical component, etc. In the present embodiment, the positioning member 1213 is constructed as a limiting ejector pin. The size of the limiting ejector pin is adapted to the size of the pin 7 and can be inserted into the hole of the pin 7. When in use, the bottom of the limiting ejector pin can be controlled to press against the hole of the pin 7, and then the panel 8 under the pin 7 is simultaneously fixed in the receiving groove 111a of the first turntable 111 by pressing the pin 7. In this way, the force generated by the panel removal device 122 can be resisted to avoid being moved out of the first turntable 111. Since the bottom end of the limiting ejector pin is higher than the upper end surface of the panel 8 when the limiting ejector pin is in the second position, the panel 8 does not contact the limiting ejector pin, so that the panel 8 without the pin 7 is moved out of the first turntable 111 by the force generated by the panel removal device 122, thereby ensuring the assembly quality of the button unit 9.

[0061] See also Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the panel removal device 122 is configured as an airflow generator, and the airflow generator is configured to generate airflow at the waste discharge station F3 to remove the panel 8 without the pins 7 assembled thereon from the turntable assembly 110. In this embodiment, the panel removal device 122 further includes a guide pipe, which is connected to the airflow generator, and is attached to the pin positioning device 121. The airflow outlet of the guide pipe faces outward along the radial direction of the turntable assembly 110, and can generate airflow at the waste discharge station F3 to remove the panel 8 lacking the pins 7 from the first turntable 111. It should be noted that the airflow generator can be any one of an air tank and an air pump.

[0062] See also Figure 2 and Figure 5As shown, the assembly system 100 further includes a first waste discharge member 130 and a second waste discharge member 140, wherein the first waste discharge member 130 is installed at the pin assembly station F2 to receive the dropped pins 7; the second waste discharge member 140 is installed at the waste discharge station F3 to receive the panel 8 moved out of the first turntable 111 by the panel removal device 122. In this embodiment, the first waste discharge member 130 is configured as a first material receiving pipe, the upper end opening of which is located below the first turntable 111 and at the pin assembly station F2 to receive the dropped pins 7, and the second waste discharge member 140 is installed at the waste discharge station F3 to receive the panel 8 moved out of the first turntable 111 by the panel removal device 122. The outlet 140 is configured as a second material receiving pipe, and the upper end of the second material receiving pipe has a receiving cover, which is arranged on the outer side of the first turntable 111 and located at the waste discharge station F3 to receive the removed panel 8; further, the lower port of the first material receiving pipe is connected to the second material receiving pipe, and the lower end of the second material receiving pipe is respectively provided with a first discharge port suitable for discharging the panel 8 and a second discharge port suitable for discharging the pin 7. The above structure makes the equipment more compact as a whole, and enables the pin 7 and the panel 8 to be discharged from the same area, which is convenient for receiving the pin 7 and the panel 8 and has good practicality.

[0063] See also Figure 1 and Figure 2 As shown, the button automatic production equipment also includes a first feeding device 400 and a second feeding device 500, wherein the discharge end of the first feeding device 400 is aligned with the panel assembly station F1, so as to be suitable for placing the panel 8 on the first turntable 111 one by one, and the discharge end of the second feeding device 500 is aligned with the pin assembly station F2, so as to be suitable for placing the pins 7 on the first turntable 111 one by one. It should be noted that since the receiving slot 111a of the first turntable 111 first receives the panel 8 and then receives the pins 7, the pins 7 can fall into the groove 81 of the panel 8 under the guidance of the positioning hole of the turntable assembly 110; if there is no panel 8 in the receiving slot 111a, the pins 7 will automatically fall into the first receiving pipe through the drop hole 111b for recycling, thereby improving the assembly quality of the button. The first feeding device 400 and the second feeding device 500 can both use commercially available vibrating screw feeders, which are mature in technology and highly reliable.

[0064] See also Figure 1 , Figure 8 and Fig. 9As shown, the welding system 200 includes a second turntable 210 and a welding mechanism 230. The second turntable 210 is rotatably arranged on the frame 6 and is located on one side of the first turntable 111 and is tangentially arranged with the first turntable 111.
