It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" 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 an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The utility model will now be further described in conjunction with the accompanying drawings.

[0033] The present invention provides a bottle cap riveting device with independent temperature control, such as Figures 1 to 3 As shown, the independently temperature-controlled bottle cap riveting device includes a riveting platform 1, a telescopic mechanism 2 is arranged above the riveting platform 1, a plurality of working rods 3 are connected to the output end of the telescopic mechanism 2, a heating component 4 is arranged at one end of the working rod 3, a ferrule 5 is fixed on the outer side of the heating component 4, a mounting hole 6 is arranged on the ferrule 5, a temperature sensor component 7 is installed through the mounting hole 6, a signal output end of the temperature sensor component 7 is connected to a signal input end of an industrial controller 8, and the signal output end of the industrial controller 8 is connected to the telescopic mechanism 2 and the signal input end of the heating component 4.

[0034] It should be noted that the temperature sensing component 7 described herein refers to an electronic component that can detect the temperature around the component, and common ones include thermocouples, temperature sensors, etc. The heating component 4 is a thermal element for riveting the bottle cap, such as a hot riveting head, etc. The heating component 4 is equipped with an electric heating element, such as a heating wire, a heating plate, etc. The signal output terminal of the industrial controller 8 is connected to the electric heating element configured in the heating component 4, which is used to control the power of the electric heating element.

[0035] Please combine Figure 2 , Figure 2The arrows in the middle show the connection mode of each component and the signal flow between each connected component. The utility model can realize independent temperature control. The specific principle is as follows: the industrial controller 8 obtains the temperature signal fed by the temperature sensor component 7. Since the present embodiment adopts a fixed ring 5 outside the heating component 4 and sets a mounting hole 6 on the ring 5 to assemble the temperature sensor component 7, the collected temperature signal is closer to the riveting point and the temperature signal is more accurate. After obtaining the relevant temperature signal, the industrial controller 8 controls the working power of the heating component 4 according to the preset temperature threshold (the temperature threshold is determined according to the temperature required for the bottle caps of different materials when riveting, and the temperature thresholds corresponding to the bottle caps of different materials will be different). If the temperature signal is lower than the temperature threshold, the working power of the heating component 4 is increased, otherwise the working power of the heating component 4 is reduced. The control method of the working power of the heating component 4 includes but is not limited to a frequency converter connected to the heating component 4. The industrial controller 8 is connected to the heating component 4 through the frequency converter to control the power of the heating component 4 by controlling the frequency converter. Within a certain period of time, which is determined based on the heating efficiency of the heating component 4, if the temperature signal fed by the temperature sensing component 7 is always lower than the temperature threshold or the temperature signal decreases over time while being lower than the temperature threshold, it indicates that the heating component 4 has a fault and cannot work normally. At this time, the industrial controller 8 controls the telescopic mechanism 2 to stop working, that is, shuts down the independently temperature-controlled bottle cap riveting device, and repairs the working rod 3 with the faulty outlet to ensure the output of good bottle caps and improve the yield rate.

[0036] In some embodiments, Figure 3 As shown, a turntable 9 is rotatably provided above the riveting platform 1 , and the turntable 9 is located between the riveting platform 1 and the telescopic mechanism 2 . Notches 10 are distributed in an array on the turntable 9 .

[0037] The bottle caps 11 to be riveted are placed on the riveting platform 1. When the turntable 9 rotates, the bottle caps 11 to be riveted are pushed through the notch 10. During operation, the movement of the turntable 9 and the telescopic mechanism 2 are staggered. For example, when the telescopic mechanism 2 drives the working rod 3 to rivet the bottle caps 11 to be riveted, the turntable 9 is stationary. After the telescopic mechanism 2 completes one round of telescoping, i.e., one round of riveting, the turntable 9 works to send out the riveted bottle caps 12. This cycle can realize automated bottle cap riveting.

[0038] like Figure 4As shown, a riveting guardrail 12 may be provided at the upper end of the riveting platform 1, and the riveting guardrail 12 is used to prevent the bottle caps 11 to be riveted or the riveted bottle caps from falling off the riveting platform 1 under the drive of the notch 10 on the turntable 9 or under the action of other external forces. It can be understood that the riveting guardrail 12 does not completely seal the riveting platform 1, but should leave an opening, for example, two openings are provided corresponding to the feed port and the discharge port of the riveting platform 1, wherein the feed port is used to feed the bottle caps 11 to be riveted, and the discharge port is used to feed the riveted bottle caps 12.

[0039] In some embodiments, Figure 4 As shown, the independently temperature-controlled bottle cap riveting device also includes a first feeding mechanism 13 and a second feeding mechanism 14, wherein the discharge port of the first feeding mechanism 13 is arranged corresponding to the feed port of the riveting table 1, and the feed port of the second feeding mechanism 14 is arranged corresponding to the discharge port of the riveting table.

[0040] In some embodiments, Figure 4 As shown, the independently temperature-controlled bottle cap riveting device further includes a workbench 18 , and the riveting table 1 , the first feeding mechanism 13 and the second feeding mechanism 14 are all arranged at the upper end of the workbench 18 .

[0041] In some embodiments, the specific structures of the first feeding mechanism 13 and the second feeding mechanism 14 are provided, such as Figure 3 , Figure 4 and Figure 5 As shown, the first feeding mechanism 13 includes a first feeding platform 1301 and a first feeding tray 1302 . The first feeding tray 1302 is rotatably disposed above the first feeding platform 1301 . The first feeding tray 1302 is provided with first notches 1303 in an array.

[0042] like Figure 4 As shown, the second feeding mechanism 14 includes a second feeding platform 1401 and a second feeding tray 1402 . The second feeding tray 1402 is rotatably disposed above the second feeding platform 1401 . The second feeding tray 1402 is provided with second notches 1403 in an array.

[0043] The first feeding mechanism 13 and the second feeding mechanism 14 have the same working principle, but different functions. The first feeding mechanism 13 is used to feed the bottle caps 11 to be riveted into the riveting platform 1, and the second feeding mechanism 14 is used to feed the riveted bottle caps 12 out.

[0044] During operation, the bottle caps 11 to be riveted are placed on the first feeding platform 1301 at a position corresponding to the first notch 1303, and the first feeding tray 1302 rotates to drive the bottle caps 11 to be riveted to rotate on the first feeding platform 1301 and move toward the feed port of the riveting platform 1. The first feeding platform 1301 is a platform body with a first guardrail 1304 at the upper end, and an opening is correspondingly provided on the first guardrail 1304 corresponding to the feed port of the riveting platform 1, so that when the bottle caps 11 to be riveted move to the feed port, they enter the riveting platform 1 from the opening provided on the first guardrail 1304, and the speed of the turntable 9 can be adjusted so that each bottle cap 11 to be riveted enters the notch 10, and each time a bottle cap 11 to be riveted enters, the turntable 9 rotates once to leave a notch 10. As an example only, during the feeding process, such as when the turntable 9 is stationary, the telescopic mechanism 2 works one stroke. It should be noted that the telescopic mechanism 2 is not provided with a working rod 2 at the position corresponding to the feeding and discharging port of the riveting table 1, so that the telescopic mechanism 2 can work when the riveting table 1 receives the material, realizing the riveting work of being basically fully automated. That is to say, in the process of the first feeding mechanism 13 feeding a bottle cap 11 to be riveted, the telescopic mechanism 2 works one stroke, and then the turntable 9 rotates one stroke again, and this cycle is repeated. In this process, if multiple working rods 3 are controlled by a telescopic cylinder, a bottle cap 11 to be riveted will undergo multiple downward pressing and heating operations during the riveting process, and finally obtain the riveted bottle cap 12. If a working rod 3 is controlled by a telescopic cylinder, then according to actual needs, a bottle cap 11 to be riveted will undergo at least one downward pressing and heating operation during the riveting process, and finally obtain the riveted bottle cap 12.

[0045] When the riveted bottle caps 12 are discharged, the turntable 9 is rotated a stroke so that the riveted bottle caps 12 are disengaged from the opening (i.e., the discharge port) on the riveting table 1 to the position corresponding to the second notch 1403 on the second feeding table 1401, and then the second feeding tray 1402 is rotated to feed the riveted bottle caps 12 out.

[0046] Exemplarily, the turntable 9, the first feeding tray 1302 and the second feeding tray 1402 can be driven to rotate by a motor respectively, wherein the motor is not shown in the figure due to obstruction, and the motors that drive the turntable 9, the first feeding tray 1302 and the second feeding tray 1402 respectively are arranged below the riveting table 1, the first feeding table 1301 and the second feeding table 1401, and their rotating shafts pass through the middle of the riveting table 1, the first feeding table 1301 and the second feeding table 1401 respectively, and then are assembled through the axial holes set in the center of the turntable 9, the first feeding tray 1302 and the second feeding tray 1402, so that the turntable 9, the first feeding tray 1302 and the second feeding tray 1402 can be rotatably installed above the riveting table 1, the first feeding table 1301 and the second feeding table 1401, thereby realizing the conveying function of the bottle cap products located on the riveting table 1, the first feeding table 1301 and the second feeding table 1401.

[0047] For example, during the riveting process of the bottle caps, the first feeding mechanism 13 and the second feeding mechanism 14 can be in continuous operation, that is, the first feeding disc 1302 and the second feeding disc 1402 can be continuously rotated at a set speed, while the turntable 9 is intermittently operated, so the speed of the turntable 9 in one stroke (that is, a certain notch 10 rotates a certain angle) should be higher than the speed of the first feeding disc 1302 and the second feeding disc 1402, so that the fully automatic production process of the bottle cap riveting can be realized. In the case of a fault in the heating component 4, the first feeding mechanism 13 and the second feeding mechanism 14 should also stop running.

[0048] In some embodiments, the discharge port of the second feeding mechanism 14 is provided with a guide trough 1404. It can be understood that in order to prevent the riveted bottle caps 12 from falling off the first feeding platform 1401, the first feeding platform 1401 is provided with a platform body with a second guardrail 1405, and the second guardrail 1405 is provided with two openings, which are the feed port and the discharge port of the second feeding mechanism 14, respectively. The guide trough 1404 is correspondingly provided at the opening position of the second guardrail 1405, and the guide trough 1404 is used to guide the bottle caps of the riveted bottle caps 12 out. After being guided out, they can be sent to the next process or temporarily stored. For example, a conveying platform can be built at the discharge position of the guide trough 1404 for conveying, and a material frame can be set at the discharge position of the guide trough 1404 for temporary storage.

[0049] In some embodiments, Figure 6 and Figure 7As shown, the independently temperature-controlled bottle cap riveting device also includes an automatic feeding mechanism 15, which includes a first vibrating loader 1501, a second vibrating loader 1502, a first conveying component 1503 and a second conveying component 1504, the discharge ends of the first vibrating loader 1501 and the second vibrating loader 1502 are respectively connected to the feed ends of the first conveying component 1503 and the second conveying component 1504, the material conveying height of the second conveying component 1504 is greater than the material conveying height of the first conveying component 1503, the discharge ends of the first conveying component 1503 and the second conveying component 1504 correspond to the feed port of the first feeding mechanism 13, and a baffle 1505 is provided on the first feeding mechanism 13 corresponding to the discharge end of the second conveying component 1504.

[0050] In this embodiment, the first conveying assembly 1503 and the second conveying assembly 1504 can be parallel to each other, have a certain height difference and be arranged obliquely. Figure 5 Of course, the first conveying assembly 1503 and the second conveying assembly 1504 may also be other conveying equipment with a certain height difference, such as a belt conveyor, a roller conveyor, etc.

[0051] In the specific implementation, take the aluminum-plastic bottle cap as an example. Figure 8 As shown, the bottle cap 11 to be riveted refers to the cover body where the aluminum cover 1101 is placed on the plastic cover 1102 but the aluminum cover 1101 and the plastic cover 1102 are not riveted together, and the riveted bottle cap 12 refers to the cover body where the aluminum cover 1101 and the plastic cover 1102 are fixed. At this time, the plastic cap is conveyed to the first conveying assembly 1503 by the first vibrating loader 1501, and then enters the position of the first feeding table 1301 corresponding to the first notch 1303, while the aluminum cap is conveyed to the second conveying assembly 1504 by the second vibrating loader 1502. The second conveying assembly 1504 and the first conveying assembly 1503 theoretically have almost the same feeding speed, and the aluminum cap will be offset due to the resistance of the baffle 1505. This process takes time. It is because of this time difference that the plastic cap will first arrive at the first feeding table 1301, and move a certain distance within this time difference, and then reach the falling position of the aluminum cap. At this time, the aluminum cap is automatically placed in the plastic cap to form the bottle cap 11 to be riveted.

[0052] The design of the automatic feeding mechanism 15 can realize automatic batching, further improve the automation level, and increase the output of bottle caps.

[0053] In some embodiments, Figure 4As shown, the upper end of the workbench 1 supports a mounting assembly 17 through a plurality of support columns 16, and the lower end of the mounting assembly 17 is provided with the telescopic mechanism 2. The mounting assembly 17 can be implemented as a plate-like structure, and the plate-like structure can also be provided with some through holes for heat dissipation, or some heat sinks can be added to avoid excessive temperature concentration above the riveting table 1, resulting in a continuous rise in temperature during the riveting process, which affects the riveting of the bottle cap.

[0054] Exemplarily, the telescopic mechanism 2 includes a telescopic cylinder (not shown in the figure due to obstruction) and a mounting plate 201 connected to the telescopic end of the telescopic cylinder, and a plurality of working rods 3 are arranged on the mounting plate 201, that is, this embodiment uses a telescopic cylinder to uniformly control the telescopic movement of a plurality of working rods 3. The telescopic control can be achieved by connecting the industrial controller 8 and the telescopic cylinder signal, thereby ensuring that the working stroke of each working rod 3 is consistent, and the control is simpler and easier to implement, and the requirements for the control program are lower.

[0055] In another exemplary embodiment, the telescopic mechanism 2 may include a mounting plate, on which a plurality of telescopic cylinders are respectively arranged, and each telescopic cylinder is respectively connected to a working rod 3, that is, a distributed control strategy is adopted. Compared with the overall downward pressing riveting strategy described above, this structure is more flexible.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
