Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment, and in particular to a connection structure and adhesive coating device. Background Technology

[0002] Glue guns are typically mounted on the robotic arm of a robot and operated by the robotic arm to perform the glue application process. On one hand, the glue gun is fixed to the robotic arm via a connecting structure, allowing the robotic arm to move the glue gun as a whole. On the other hand, the robotic arm has a rotating flange, and the glue gun itself has a rotating drive unit. The rotating drive unit is connected to the rotating flange, and the rotating flange controls the glue gun's operation by driving the rotating drive unit.

[0003] In the prior art, the connecting structure includes two semi-ring parts and two bolts. The glue gun is fixedly connected to the two semi-ring parts. The ends of the two semi-ring parts are connected one after the other by bolts to form a ring-shaped connecting structure, thereby holding the connecting structure tightly on the outer periphery of the robotic arm, and thus fixing the glue gun on the robotic arm.

[0004] However, when the rotating flange rotates, especially at high speeds, the bolts are prone to loosening due to vibration. Even a slight loosening of the bolts can cause a sudden decrease in pressure between the connecting structure and the robotic arm, which in turn reduces the friction between the connecting structure and the robotic arm. This can lead to the failure of the glue gun to be fixed on the robotic arm. Under the drive of the rotating flange, the glue gun will twist, and may even be damaged. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figure 1 As shown, this embodiment provides a connection structure and an adhesive application device. The adhesive application device includes a robotic arm 100, an adhesive application gun 200, and the aforementioned connection structure. This connection structure is used to connect the robotic arm 100 and the adhesive application gun 200, with the robotic arm 100 connected to the adhesive application gun 200 via the connection structure.

[0036] The connection structure includes a main body 300 and multiple fastening connectors 400. Specifically, a glue gun 200 is connected to the main body 300, which includes an annular clamping assembly 310 forming an enclosing space. The annular clamping assembly 310 can clamp tightly around the outer periphery of the robotic arm 100. Each fastening connector 400 is arranged circumferentially along the annular clamping assembly 310, and the annular clamping assembly 310 is fastened to the robotic arm 100 through each fastening connector 400.

[0037] The connection structure provided in this embodiment has multiple fastening connectors 400 arranged circumferentially, which makes the distribution of fastening force between the connection structure and the robotic arm 100 more uniform, improving the reliability and stability of the fastening connection. In addition to being able to hold the outer periphery of the robotic arm 100, the annular clamping assembly 310 is also fastened to the robotic arm 100 through each fastening connector 400. Even if the clamping force of the annular clamping assembly 310 decreases, each fastening connector 400 still fastens the connection structure to the robotic arm 100, thereby ensuring that the connection structure and the robotic arm 100 remain relatively fixed, improving the connection reliability between the connection structure and the robotic arm 100, thereby improving the connection reliability between the glue gun 200 and the robotic arm 100, and avoiding damage to the glue gun 200.

[0038] like Figures 2-4 As shown, optionally, the fastening connector 400 includes threaded components, and the annular clamping assembly 310 has first through holes 313 corresponding to the threaded components. Each threaded component passes through its corresponding first through hole 313 and is threadedly connected to the robotic arm 100. That is, the annular clamping assembly 310 is also threadedly connected to the robotic arm 100 through each fastening connector 400. Threaded connections offer high reliability and facilitate disassembly and assembly for replacement or maintenance. Threaded components can be bolts, screws, etc. Specifically, the robotic arm 100 has a fixed flange 101, and the threaded component is threadedly connected to the fixed flange 101. In other embodiments, the fastening connector 400 can also be a cylindrical pin, and the annular clamping assembly 310, in addition to clamping onto the robotic arm 100, is also fastened to the robotic arm 100 through the cylindrical pin.

[0039] like Figure 2 and Figure 3 As shown, optionally, the threaded component is a first fastening bolt, which includes a screw and a screw head at one end of the screw. The screw passes through the first through hole 313 and is threadedly connected to the robotic arm 100, while the screw head abuts against the annular clamping assembly 310. In other words, by pressing the annular clamping assembly 310 with the screw head, the annular clamping assembly 310 is limited and fastened. The first fastening bolt can be a common bolt, a special bolt with a self-locking function, or a bolt with an anti-loosening washer.

[0040] like Figure 2As shown, optionally, the annular clamping assembly 310 has a groove 314 on one end face in the axial direction, and a first through hole 313 is provided at the bottom of the groove 314. Specifically, the first through hole 313 is provided on the bottom wall of the groove 314. The groove 314 provides space for the fastening connector 400 to pass through the first through hole 313, and facilitates engagement with the protrusion on the robotic arm 100 for positioning. In this embodiment, the annular clamping assembly 310 is coaxially arranged with the robotic arm 100, and the first through hole 313 extends through the annular clamping assembly 310 in the axial direction.

[0041] like Figure 2 and Figure 3 As shown, optionally, the annular clamping assembly 310 includes at least two clamping components 311 and at least two circumferential connectors 312. The at least two clamping components 311 are distributed circumferentially, and any two adjacent clamping components 311 are detachably connected by the circumferential connectors 312. The annular clamping assembly 310, composed of at least two clamping components 311, facilitates flexible assembly according to the size of the robotic arm 100, improving the versatility and applicability of the connection structure. The circumferential connectors 312 enable detachable connection between adjacent clamping components 311, facilitating the installation or removal of the annular clamping assembly 310 on the robotic arm 100. In this embodiment, two clamping components 311 are provided, each clamping component 311 being semi-annular to reduce the amount of disassembly and assembly work. Multiple circumferential connectors 312 can be provided between adjacent clamping components 311 to increase the reliability of the connection.

[0042] like Figure 2 and Figure 3 As shown, optionally, each clamping component 311 is securely connected to the robotic arm 100 via multiple fastening connectors 400. This arrangement ensures that each clamping component 311 is reliably secured to the robotic arm 100, further enhancing the stability and reliability of the connection structure during connection. In this embodiment, two fastening connectors 400 form a group, and each clamping component 311 is connected to two groups of fastening connectors 400.

[0043] like Figures 2-4 As shown, in this embodiment, two adjacent clamping components 311 are bolted together by a circumferential connector 312. The bolted connection facilitates assembly and disassembly, and also allows for easy adjustment of the clamping force of the annular clamping assembly 310. Specifically, in the two adjacent clamping components 311, one clamping component 311 has a second through hole 315, and the other clamping component 311 has a threaded hole. The circumferential connector 312 is a bolt; the bolt shank passes through the second through hole 315 and is threaded into the threaded hole, while the bolt head abuts against the clamping component 311 with the second through hole 315. In other embodiments, the two adjacent clamping components 311 can also be connected in other ways by the circumferential connector 312, such as a magnetic connection.

[0044] like Figures 1-4 As shown, optionally, the main structure 300 also includes an avoidance extension assembly 320. One end of the avoidance extension assembly 320 is disposed on the annular clamping assembly 310, and the avoidance extension assembly 320 extends axially along the annular clamping assembly 310. The other end of the avoidance extension assembly 320 extends beyond the end of the robotic arm 100, and the glue application gun 200 is disposed at the other end of the avoidance extension assembly 320. By extending and protruding the end of the robotic arm 100 in the longitudinal direction through the avoidance extension assembly 320, a suitable installation position and space are provided for the glue application gun 200, avoiding structural interference between the glue application gun 200 and the robotic arm 100. The glue application gun 200 can be connected to the avoidance extension assembly 320 by bolt connection, pin connection, or welding, etc.

[0045] Optionally, the avoidance extension component 320 is located on the outer periphery of the annular clamping component 310. Generally, the robotic arm 100 also has a rotating flange 102 at its axial end, and the avoidance extension component 320 is located on the outer periphery of the annular clamping component 310, thereby maximizing the space inside the avoidance extension component 320 to provide avoidance space for the rotating flange 102 and avoid interference.

[0046] like Figures 1-3 As shown, optionally, the avoidance extension assembly 320 includes a first extension plate 321 and a second extension plate 322. The first extension plate 321 and the second extension plate 322 are spaced apart circumferentially along the annular clamping assembly 310 and are arranged opposite each other radially in the annular clamping assembly 310. The radially opposite arrangement of the first extension plate 321 and the second extension plate 322 balances the force on the glue gun 200 and provides sufficient viewing space between the first extension plate 321 and the second extension plate 322, providing an observation view for structures such as the rotating flange 102, which is beneficial for assembly operations and equipment maintenance.

[0047] like Figures 1-3 As shown, optionally, the connection structure also includes multiple second fastening bolts 323, through which the glue gun 200 is connected to the avoidance extension assembly 320. That is, the glue gun 200 is bolted to the avoidance extension assembly 320, facilitating the installation and removal of the glue gun 200, and simplifying maintenance and replacement. The multiple second fastening bolts 323 ensure a secure installation of the glue gun 200 on the avoidance extension assembly 320, reducing the risk of the glue gun 200 loosening or falling off during operation.

[0048] The glue application device provided in this embodiment uses a connection structure to connect the robotic arm 100 and the glue application gun 200. The connection structure on the robotic arm 100 is more reliable, which improves the reliability and stability of the connection between the glue application gun 200 and the robotic arm 100 and reduces the occurrence of connection failure of the glue application gun 200.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
