[0027] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] The terms "first," "second," and the like in this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0029] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In the field of industrial production and safety packaging, lead sealing and pin threading operations are an important process, which is widely used in the sealing and protection of items such as pipes, containers, and cargo boxes. Traditionally, this operation mainly relies on manual work, which is not only inefficient, but also prone to operational errors and safety hazards. With the rapid development of automation technology, how to automate lead sealing and pin threading operations, improve production efficiency, and reduce manual intervention has become a problem that needs to be solved urgently in this field. The present application provides a lead sealing device, which can be used to seal items, save labor costs, and has a high efficiency of lead sealing. The lead sealing device provided by the present application will be introduced in detail below.

[0031] See also Figure 1 As shown, Figure 1 1 is a schematic structural diagram of an embodiment of a lead sealing device and an article to be sealed provided by the present application. Specifically, the lead sealing device 10 may include: a wire threading mechanism 11 and a cover mechanism 12 provided on the upper side of the wire threading mechanism 11. Optionally, the lead sealing device 10 may further include a wire feeding mechanism 13.

[0032] like Figure 2 and Figure 3 As shown, Figure 2 yes Figure 1 The structural diagram of the lead sealing device shown in FIG. Figure 3 yes Figure 2 As shown in the exploded structural diagram of the lead sealing device, the threading mechanism 11 includes a support frame 111 and a track plate 112 provided on the support frame 111 .

[0033] like Figure 3 and Figure 4 As shown, Figure 4 yes Figure 3 A partial structural diagram of the lead sealing device is shown. Track plate 112 is provided with a track groove 115, a seal positioning opening 113, and a pin positioning opening 114. One end of track groove 115 communicates with seal positioning opening 113, while the other end of track groove 115 communicates with pin positioning opening 114. Seal positioning opening 113 is used to receive and secure seal block 30, while pin positioning opening 114 is used to receive pin 21 on object 20. Pin 21 is installed on object 20 as required.

[0034] The sealing wire 40 passes through the track groove 115 and penetrates the sealing block 30 and the pin 21 to seal the object 20. Specifically, the sealing wire 40 passes through one end of the track groove 115 through a sealing hole (not shown) in the sealing block 30, then moves along the track groove 115 to the pin positioning opening 114 at the other end. The sealing wire 40 passes through the fixing hole (not shown) of the pin 21, then returns to the other end of the track groove 115 through the track groove 115 and passes through another sealing hole (not shown) in the sealing block 30, thereby completing the sealing of the object 20.

[0035] The lead seal block 30 can be automatically placed in the lead seal positioning opening 113 for securing by a robot, thereby reducing manual intervention. In other embodiments, the lead seal block 30 can also be manually placed in the lead seal positioning opening 113 for securing. After the lead seal block 30 is secured, the lead seal hole on the lead seal block 30 is aligned with the notch of the track groove 115 (the connection between the track groove 115 and the lead seal positioning opening 113), so that the lead seal wire 40 can pass through the track groove 115 and enter and exit the lead seal hole.

[0036] like Figure 4 As shown, a suction cup 117 may be provided within the seal positioning opening 113 to secure the seal block 30. Preferably, a recessed platform 1131 may be provided at the edge of the seal positioning opening 113. The suction cup 117 can adsorb the seal block 30 onto the recessed platform 1131, thereby positioning the seal block 30 via the recessed platform 1131. If the seal block 30 is circular, it can be positioned circumferentially around the periphery of the recessed platform 1131 to ensure that the seal block 30 is secured in all degrees of freedom.

[0037] like Figure 4 As shown, the pin positioning opening 114 is provided at the end of the track plate 112 , and the pin positioning opening 114 can be a “U”-shaped alignment opening, or a “V”-shaped alignment opening, etc. When threading the wire, the pin 21 on the object 20 is placed in the pin positioning opening 114 .

[0038] like Figure 2 and Figure 3 As shown, the cover mechanism 12 is movably mounted on the track plate 112. Specifically, the cover mechanism 12 has a first state and a second state. In the first state, the cover mechanism 12 covers the track plate 112, sealing at least a portion of the track groove 115. In the second state, the cover mechanism 12 is positioned on one side of the track plate 112, exposing the seal positioning opening 113 and the track groove 115, allowing the seal block 30 to be placed or removed.

[0039] In the above embodiment, the cover mechanism 12 can form a sealed tunnel-like path in the track groove 115, and the sealing wire 40 will not deviate from the track during the perforation process, thereby improving the yield of the seal. After the sealing is completed, the cover mechanism 12 can be removed and the sealing block 30 and the sealing wire 40 can be completely removed from the track groove 115.

[0040] Optionally, the cover mechanism 12 may include a first cover 121 and a pin positioning assembly 122 connected to the first cover 121. The first cover 121 is used to cover the track groove 115 to form a sealed tunnel-like path. The pin positioning assembly 122 can be used to position the pin 21. For example, the pin positioning assembly 122 can adjust the orientation of the pin 21 and can be used to axially position the pin 21.

[0041] In the first state, the first cover 121 covers the track plate 112 to seal at least a portion of the track groove 115, and the pin positioning assembly 122 is used to position the pin 21 within the pin positioning opening 114. In the second state, the cover mechanism 12 is located on one side of the track plate 112, exposing the seal positioning opening 113 and the track groove 115, allowing the seal block 30 to be placed or removed.

[0042] Furthermore, when the sealed article 20 needs to be sealed, the cover mechanism 12 is first placed in the second state, that is, the first cover 121 is opened to expose the seal positioning opening 113. At this time, the seal block 30 is loaded and fixed to the seal positioning opening 113. The cover mechanism 12 is then switched to the first state, covering the first cover 121. The first cover 121 is placed on the track plate 112 and covers the track groove 115. The pin positioning assembly 122 can adjust the position of the pin 21. At this time, the track groove 115 is a tunnel-type path. When the seal wire 40 moves in the track groove 115, it will not fall out, thereby improving the reliability of the wire threading.

[0043] In the above embodiment, the sealing device 10 can seal the article 20. The sealing device 10 is provided with a cover mechanism 12. This allows the track groove 115 to form a sealed tunnel-like path, and the sealing wire 40 does not deviate from the track during the perforation process. The pin positioning assembly 122 can adjust the positioning of the pin 21 without manual operation. After the sealing is completed, the cover mechanism 12 can be removed, and the sealing block 30 and the sealing wire 40 can be completely removed from the track groove 115. The sealing device 10 of the present application can improve the yield rate of the sealing and improve the efficiency of the sealing.

[0044] Alternatively, as Figure 2 As shown, the lead sealing device 10 may further include a second driving member 116 , which is disposed on the support frame 111 . The second driving member 116 is connected to the cover mechanism 12 and is used to drive the cover mechanism 12 to switch between the first state and the second state.

[0045] Specifically, if Figure 2 and 4 As shown, the second driving member 116 is disposed on the side of the support frame 111 facing away from the track pad 112. The output end of the second driving member 116 is connected to the first cover plate 121. Placing the second driving member 116 on the back side of the support frame 111 can reduce the size of the lead sealing device 10. In other embodiments, the second driving member 116 can also be fixedly connected to the track pad 112. The fixing of the second driving member 116 is within the scope of those skilled in the art and is not specifically limited here.

[0046] Optionally, the cover mechanism 12 can also be opened and closed manually, that is, the cover mechanism 12 can be placed on the track pad 112 and removed from the track pad 112 manually.

[0047] Further, if Figure 3 As shown, a blocking block 119 can be provided on one side of the track pad 112 to block the first cover plate 121. The second driving member 116 can drive the first cover plate 121 to move in a direction approaching the blocking block 119 until the first cover plate 121 abuts against the blocking block 119. In this way, the first cover plate 121 can be aligned so that the first cover plate is accurately placed on the track pad 112.

[0048] Further, if Figure 3 As shown, the pin positioning assembly 122 may include a first positioning block 124 and a first driving member 123. The first driving member 123 is connected to the first positioning block 124 and is used to drive the first positioning block 124 to move toward or away from the pin 21, thereby adjusting the orientation of the pin 21 through the end of the first positioning block 124. The front surface of the first positioning block 124 pushes the pin 21 flat to ensure that the fixing hole of the pin 21 is aligned with the track plate 112.

[0049] exist Figure 3 In the illustrated embodiment, a first positioning slot 125 is provided on the side of the first positioning block 124 close to the pin 21. The first positioning slot 125 is used to abut against one end of the pin 21. When the cover mechanism 12 is provided on the track plate 112, the first driving member 123 drives the first positioning block 124 to move toward the direction close to the pin 21, so as to adjust the orientation of the pin 21 through the first positioning slot 125. Specifically, the pin 21 can be pushed by the first positioning slot 125, so that the pin 21 is rotated to reach the correct orientation. By providing the first positioning slot 125, not only can the orientation of the pin 21 be adjusted, but the pin 21 can also be limited by the side wall of the first positioning slot 125, thereby fixing the pin 21 in the horizontal direction.

[0050] In other embodiments, the first positioning groove 125 may not be provided at the end of the first positioning block 124. The end of the first positioning block 124 is a flat surface, through which the orientation of the pin 21 is adjusted. In this way, the first positioning block 124 has a simple structure and low manufacturing cost.

[0051] Further, if Figure 2 and Figure 5 As shown, Figure 5 yes Figure 2The diagram shows a partial structure of a lead sealing device. The cover mechanism 12 further includes a second cover 126. The second cover 126 is smaller than the first cover 121 and is located at the end of the first cover 121 near the pin 21. A clearance groove 106 may be provided at the end of the first cover 121 near the pin 21, and the second cover 126 is movably disposed within the clearance groove 106. One end of the second cover 126 is connected to a first driving member 123, which is used to drive the second cover 126 toward or away from the pin 21. The second cover 126 can be used to cover the end of the track groove 115.

[0052] like Figure 2 and Figure 5 As shown, the second cover plate 126 can cooperate with one end of the first cover plate 121 to form a receiving groove (not shown in the figure), which is used to accommodate the pin 21 during lead sealing. In other embodiments, the receiving groove can also be directly provided on the end of the second cover plate 126 to receive the pin 21 during lead sealing.

[0053] like Figure 5 As shown, the length of one end of the first cover plate 121 can be greater than the length of the other end of the first cover plate 121, wherein one end of the first cover plate 121 is located at one end of the receiving slot, and the other end of the first cover plate 121 is located at the other end of the receiving slot. Setting the length of the other end of the first cover plate 121 shorter ensures that the other end of the first cover plate 121 does not interfere with the pin 21 when the first cover plate 121 moves horizontally.

[0054] In the above embodiment, the second cover plate 126 is configured to be movable. When sealing, the first cover plate 121 is placed on the track plate 112, and the second cover plate 126 moves forward so that the second cover plate 126 can cover the end of the track groove 115, and the pin 21 is located in the receiving groove formed by the second cover plate 126 and the first cover plate 121. When the sealing is completed, the second cover plate 126 moves backward (that is, moves in a direction away from the pin 21) so that the second cover plate 126 moves to the rear side of the pin 21. The cover mechanism 12 is then driven to translate by the first driving member 123. At this time, the second cover plate 126 will not interfere with the pin 21, and the other end of the first cover plate 121 is shorter and will not interfere with the pin 21, so that the cover mechanism 12 can be smoothly moved to one side of the track plate 112. In the above embodiment, the second cover plate 126 can cover the track groove 115 at the end of the track plate 112 when threading the wire, so that the sealing wire 40 will not escape from the groove. At the same time, when the cover mechanism 12 is opened, the second cover plate 126 retreats and will not be blocked by the pin 21.

[0055] Further, if Figure 5As shown, the cover mechanism 12 may further include an adapter plate 128 and a second positioning block 127. One end of the adapter plate 128 is connected to the second cover plate 126, and the other end of the adapter plate 128 is connected to the second positioning block 127. The second positioning block 127 is provided with a second positioning groove 102 for positioning the pin 21. The adapter plate 128 and the second cover plate 126 may be integrally formed. In other embodiments, the adapter plate 128 and the second cover plate 126 may also be detachably connected.

[0056] The first driving member 123 is connected to the adapter plate 128 , and the first driving member 123 drives the second cover plate 126 and the second positioning block 127 to move simultaneously through the adapter plate 128 .

[0057] When the second cover plate 126 moves forward, it also drives the second positioning block 127 forward, so that the pin 21 is located in the second positioning groove 102, thereby axially positioning the pin 21. The second positioning groove 102 and the first positioning groove 125 are arranged at intervals along the axial direction of the pin 21 to axially position the pin 21 and prevent the pin 21 from tilting.

[0058] Furthermore, if Figure 4 As shown, the track groove 115 includes a first track groove 1151 and a second track groove 1152. The first track groove 1151 is located on one side of the center line connecting the lead seal positioning opening 113 and the pin positioning opening 114, and the second track groove 1152 is located on the other side of the center line connecting the lead seal positioning opening 113 and the pin positioning opening 114. Figure 4 In the illustrated embodiment, the first track groove 1151 and the second track groove 1152 are symmetrically arranged relative to the center line connecting the lead seal positioning opening 113 and the pin positioning opening 114, so that the back and forth path of the lead seal wire 40 is more regular.

[0059] One end of the first track groove 1151 and one end of the second track groove 1152 are connected to the seal positioning opening 113, and the other ends of the first track groove 1151 and the second track groove 1152 are connected to the pin positioning opening 114. The sealing wire 40 passes through the seal block 30 from one end of the first track groove 1151 and then moves along the first track groove 1151 to the other end of the first track groove 1151. The sealing wire 40 enters the fixing hole of the pin 21 through the notch at the other end of the first track groove 1151. The sealing wire 40, which has passed through the pin 21, enters the other end of the second track groove 1152. The sealing wire 40 then moves along the second track groove 1152 to one end of the second track groove 1152 and then passes through the other sealing hole of the seal block 30, completing the sealing operation.

[0060] In the direction from the seal positioning opening 113 to the pin positioning opening 114, the distance between the first track groove 1151 and the second track groove 1152 first gradually increases and then gradually decreases. The first track groove 1151 and the second track groove 1152 are arranged in an outwardly convex arc, so that the track groove 115 is arranged in an overall fish-shaped configuration. The "fish mouth" is the pin positioning opening 114, and the "fish tail" is the seal positioning opening 113. This configuration ensures that the transition radius of the track groove 115 is relatively smooth, and the transition angle is much greater than 90 degrees. When the seal wire 40 passes through this track groove 115, it will not get stuck, thereby improving the seal threading yield rate.

[0061] In other embodiments, part of the first and second track grooves 1151, 1152 may be configured as arcs, while the rest may be configured as straight lines. For example, the track groove 115 at the "fish tail" may be configured as a straight line, while the track groove 115 at the "fish head" may be configured as an arc. This will make threading of the lead seal block 30 and the pin 21 smoother.

[0062] Further, if Figure 6 As shown, Figure 6 yes Figure 4 Schematic diagram of the structure of the first notch and the second notch at the middle seal positioning port, the connection between the track groove 115 and the seal positioning port 113 has a first notch 201 and a second notch 202 arranged opposite to each other, the first notch 201 is used to feed the seal wire 40 in the track groove 115 on one side of the seal positioning port 113 into the seal block 30, and the second notch 202 is used to feed the seal wire 40 passing through the seal block 30 into the track groove 115 on the other side of the seal positioning port 113, and the diameter of the first notch 201 is smaller than the diameter of the second notch 202.

[0063] See also Figure 7 As shown, the connection between the track groove 115 and the pin positioning hole 114 has a third slot 203 and a fourth slot 204 arranged opposite to each other. The third slot 203 is used to feed the sealing wire 40 in the track groove 115 on one side of the pin positioning hole 114 into the pin 21, and the fourth slot 204 is used to feed the sealing wire 40 passing through the pin 21 into the track groove 115 on the other side of the pin positioning hole 114. The diameter of the third slot 203 is smaller than the diameter of the fourth slot 204.

[0064] In the above embodiment, if the notch is a wire outlet (the first notch 201 and the third notch 203), that is, the sealing wire 40 enters the sealing block 30 or the pin 21 through this notch, the diameter of the notch is designed to be smaller. This reduces the freedom of the sealing wire 40 and allows the sealing wire 40 to more accurately align with the fixing hole of the pin 21 or the sealing hole of the sealing block 30. If the notch is a wire inlet (the second notch 202 and the fourth notch 204), that is, the sealing wire 40 enters the track groove 115 through this notch after passing through the sealing block 30 or the pin 21, the notch is designed to be larger, allowing the sealing wire 40 to enter the track groove 115 more smoothly. This design reduces the occurrence of abnormal situations such as the sealing wire 40 getting stuck or blocked in the track groove 115, thereby improving the yield rate of the sealing wire threading process.

[0065] like Figure 1 The wire feeder 13 is located on one side of the wire threading mechanism 11. It is used to release the wound sealing wire 40 and guide it along the track groove 115 through the sealing hole of the sealing block 30 and the fixing hole of the pin 21. The wire feeder 13 automatically feeds the sealing wire 40. The wire outlet of the wire feeder 13 is aligned with the wire inlet of the wire threading mechanism 11.

[0066] Continue reading Figure 1 、 Figure 8 and Figure 9 As shown, Figure 8 yes Figure 2 The schematic diagram of the structure of the wire cutting mechanism, support frame and track plate of the lead sealing device shown in the figure is as follows: Figure 9 yes Figure 2 The schematic diagram of the structure of the wire cutting mechanism, track plate and cover mechanism of the lead sealing device shown in FIG. The lead sealing device 10 may also include a wire cutting mechanism 14, which is arranged at one end of the wire threading mechanism 11 near the wire feeding mechanism 13. The wire cutting mechanism 14 is used to cut the lead sealing wire 40 after the wire feeding mechanism 13 releases a preset length of the lead sealing wire 40.

[0067] like Figure 8 As shown, the support frame 111 is formed with a receiving cavity 100, and the upper side of the support frame 111 is provided with a wire cutting port 103 connected to the receiving cavity 100. The wire cutting end of the wire cutting mechanism 14 passes through the wire cutting port 103 to cut the sealing wire 40. The wire cutting mechanism 14 in the sealing device 10 can adopt a fixed-length algorithm. When it is detected that the length of the sealing wire 40 released by the wire feeding mechanism 13 meets the process requirements, the wire cutting mechanism 14 automatically cuts the sealing wire 40. In this way, the automation of the sealing process can be achieved without manual intervention. In other embodiments, the sealing wire 40 can also be cut after the head end of the sealing wire 40 extends out of the end of the track groove 115. In this way, it can avoid the cutting operation before the sealing process is completed, thereby improving the yield rate of the sealing.

[0068] By way of example, the sealing process of the sealing device 10 provided in the present application will be described in detail below.

[0069] First, install the pin 21 into the fixing hole of the article 20 (such as a packaging barrel), and make the end of the pin 21 rest on the article 20 to support the pin 21. Place the pin 21 in the pin positioning port 114 of the lead sealing device 10, and the second driving member 116 opens the cover mechanism 12 to expose the lead sealing positioning port 113. The lead sealing block 30 is placed in the lead sealing positioning port 113 by a manipulator, and the lead sealing block 30 is adsorbed and fixed by the suction cup 117 in the lead sealing positioning port 113. Then, the cover mechanism 12 is driven by the second driving member 116 to move to the track plate 112 to cover the track groove 115 on the track plate 112, so that the track groove 115 forms a tunnel-like path. The pin alignment port 114 of the threading mechanism 11 is aligned with the pin 21 and positioned. The first driving member 123 drives the first positioning block 124, the second cover plate 126, and the second positioning block 127 to move forward. The second cover plate 126 covers the end of the track groove 115 and can cooperate with the first cover plate 121 to laterally clamp the pin 21. The first positioning groove 125 adjusts the orientation of the pin 21, and the first positioning groove 125 and the second positioning groove 102 axially position the pin 21.

[0070] The wire feeding mechanism 13 starts the wire feeding action, and the seal wire 40 passes through the seal 30 and the pin 21 along the track groove 115 on the track plate 112 and passes through the track plate 112. When the wire feeding mechanism 13 feeds the wire to a preset length, the wire cutting mechanism 14 cuts the seal wire 40.

[0071] The first driving member 123 in the cover mechanism 12 drives the second cover 126 and the first positioning block 124 to move backward, so that the second cover 126 will not interfere with the pin 21 when moving sideways. The second driving member 116 drives the cover mechanism 12 to move to one side of the track plate 112 to expose the sealing wire 40 and the sealing block 30. The object 20 rises or the threading mechanism 11 descends to remove the sealed sealing wire 40 and the sealing block 30 from the track plate 112, thereby completing the sealing of the object 20. Figure 10 As shown, Figure 10 1 is a schematic diagram of the structure of an article after being sealed by the sealing device of the present application, wherein the pin 21 is connected to the seal 30 via the sealing wire 40 .

[0072] The sealing device 10 of the above-described embodiment has a simple structure and low manufacturing cost, and is capable of automatically sealing an article 20. By providing a movable cover mechanism 12, the present application enables the track groove 115 to form a sealed tunnel-like path, preventing the sealing wire 40 from deviating from the track during the perforation process. The pin positioning assembly 122 can adjust the positioning of the pin 21, thereby improving the sealing yield. After sealing is completed, the cover mechanism 12 can be removed, and the sealing block 30 and sealing wire 40 can be completely removed from the track groove 115, saving labor costs and significantly improving the sealing efficiency.

[0073] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
