For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0033] The present application provides a rubber band sleeve gripper, which is used to sleeve the rubber band onto a workpiece after the rubber band is stretched out.
[0034] like Figure 1 and Figure 2 As shown, the rubber band sleeve gripper provided by the present application includes a base plate 100, a pressure plate assembly 300 and a plurality of strut assemblies 200. The base plate 100 provides a basis for the installation of the strut assembly 200 and the pressure plate assembly 300, and the strut assembly 200 and the pressure plate assembly 300 are directly or indirectly installed on the base plate 100. The base plate 100 can also be the basis for connecting the rubber band sleeve gripper provided by the present application with other mechanisms, that is, in some embodiments, a structure for connecting with a device such as a robot arm is provided on the base plate 100, and the rubber band sleeve gripper is driven to move by the robot arm, so that the rubber band sleeve gripper can grasp the rubber band from the position where the rubber band is set, move to the position where the workpiece is located, and then sleeve the rubber band on the workpiece.
[0035] Furthermore, each support rod assembly 200 includes a support rod 240, one end of which is slidably connected to the base plate 100, and the other end of which extends in a direction away from the base plate 100. When the rubber band is put on the support rod 240, the rubber band can be stretched out by sliding the two support rods 240 in directions away from each other. It is not difficult for those skilled in the art to understand that in the initial state of the rubber band, the rubber band is an annular structural member. When implementing the present application, it is not difficult for those skilled in the art to imagine that when the two support rods 240 are closest to each other (that is, the support rods 240 are located Figure 1 The two support rods 240 are then able to simultaneously extend into the inner side of the rubber band in the initial state, and then the two support rods 240 move away from each other, and the rubber band is pressed against the support rods 240 under the action of its own elastic force, that is, the support rods 240 at different positions exert forces in different directions on the rubber band to stretch the rubber band.
[0036] Further, the pressure plate assembly 300 includes a first pressure plate 310 and a second pressure plate 320 connected to each other, wherein the first pressure plate 310 is located between the second pressure plate 320 and the bottom plate 100, wherein the second pressure plate 320 is used to push the rubber band on the support rod 240 away from the support rod 240. Specifically, the first pressure plate 310 is provided with a strip-shaped first channel 311, and the second pressure plate 320 is provided with a strip-shaped second channel 321. The number of the first channel 311 and the second channel 321 corresponds to the number of the support rod 240, and the positions of the first channel 311 and the second channel 321 also correspond to the positions of the support rod 240, and the extending directions of the first channel 311 and the second channel 321 correspond to the sliding direction of the support rod 240, that is, as Figure 1 and Figure 2 As shown, the second pressing plate 320 is provided with a second channel 321 which is parallel to the first channel 311 in the first pressing plate 310; the movement process of the support rod 240 is manifested as movement along the extension direction of the first channel 311 and the second channel 321. Figure 1 and Figure 2 In the illustrated embodiment, the first pressing plate 310 and the second pressing plate 320 are both plate-shaped structural members and are arranged parallel to each other; the first pressing plate 310 and the second pressing plate 320 are rigidly connected via a connecting column 330 to improve the rigidity of the pressing plate assembly 300. Of course, in other embodiments, the first pressing plate 310 and the second pressing plate 320 may also have a certain angle.
[0037] The support rod 240 can pass through the corresponding first channel 311 and the second channel 321 in sequence. Figure 1 and Figure 2 As shown, the support rod 240 can pass through the first channel 311 and the second channel 321 at the same time, one end of the support rod 240 is slidably connected to the bottom plate 100, and the other end is located on the side of the second pressing plate 320 away from the bottom plate 100. Figure 1 In the state shown, the second pressing plate 320 moves along the extension direction of the support rod 240 away from the bottom plate 100, so that the rubber bands sleeved on the plurality of support rods 240 can be pushed away from the first pressing plate 310 by the second pressing plate 320 until the rubber bands are detached from the support rod 240.
[0038] Strut 240 from Figure 1 When the position shown moves along the first channel 311 and the second channel 321 in the direction away from the support rod 240 in the other support rod assembly 200, the end of the support rod 240 located at the second pressing plate 320 away from the bottom plate 100 can stretch the rubber band. Since the end of the support rod 240 away from the bottom plate 100 is a free end, this end is easily deformed under the elastic force of the rubber band, so that the free ends of the two support rods 240 bend in the direction of approaching each other, thereby making it easy for the rubber band to automatically detach from the free end of the support rod 240. In the technical solution provided in the present application, the pressing plate assembly 300 includes a first pressing plate 310 and a second pressing plate 320. When the support rod 240 stretches the rubber band, the free end of the support rod 240 is still located in the second channel 321 in the second pressing plate 320. Therefore, the deformation of the free end of the support rod 240 will be limited by the second pressing plate 320, thereby reducing the deformation of the support rod 240, so that the rubber band is not easy to automatically fall off from the support rod 240.
[0039] exist Figure 1 In the embodiment shown, the extension directions of the support rods 240 are parallel to each other, for example, the surface of the bottom plate 100 facing the support rods 240 is a plane, and the extension directions of the support rods 240 are perpendicular to the surface of the bottom plate 100. In other embodiments, the extension direction of the support rods 240 may also be at a certain angle to the surface of the bottom plate 100, for example, the free end of the support rod 240 is away from the bottom plate 100. Figure 1 The center position shown is deviated, so when the support rod 240 moves in a direction away from each other, the rubber band has a tendency to move toward the bottom plate 100, thereby effectively improving the problem of the rubber band automatically falling off the support rod 240.
[0040] exist Figure 1 In the embodiment shown, the struts 240 move along the radial direction of the circumference, and the movement directions of the struts 240 are not parallel; accordingly, the first channel 311 and the second channel 321 also move along the circumference and extend along the radial direction of the circumference. In other embodiments, the struts 240 can also move in a parallel manner, as long as the rubber band in the initial state can be stretched, and those skilled in the art can reasonably select the movement mode of the struts 240 according to the shape of the stretched rubber band as needed.
[0041] Further, if Figure 1As shown, the second pressing plate 320 is also provided with an avoidance hole 340, and the avoidance hole 340 is used to avoid the workpieces that need to be bundled. The avoidance hole 340 can be set at the center position of the second pressing plate 320, so that the second pressing plate 320 has an annular structure. One end of the second channel 321 extends to the avoidance hole 340, that is, in the process of stretching the rubber band, the strut 240 moves outward from the center position located on the inner side of the avoidance hole 340 and enters the second channel 321. When the strut 240 moves to the second channel 321, the rubber band is stretched to a greater extent, and the force acting on the strut 240 is greater. In this case, the side wall of the second channel 321 can limit the deformation of the strut 240, thereby reducing the deformation of the strut 240. It is not difficult to understand that the use of Figure 1 and Figure 2 When the rubber band sheathing gripper is used to bundle workpieces, the second pressure plate 320 can move to a position lower than the top of the workpiece, that is, when the rubber band is about to separate from the support rod 240, the lower surface of the second pressure plate 320 can be located in the middle of the workpiece in the extension direction of the support rod 240, so that the rubber band is separated from the support rod 240 and bundled in the middle of the workpiece, so as to achieve a better bundling effect on the workpiece.
[0042] Combination Figure 1 It is not difficult to understand that when the rubber band is stretched on the support rod 240 and the support rod 240 is located on the inner side of the second channel 321, the projection of the stretched rubber band along the extension direction of the support rod 240 will at least partially fall on the second pressure plate 320. Therefore, if the second pressure plate 320 moves along the extension direction of the support rod 240 away from the first pressure plate 310, the second pressure plate 320 will push the rubber band to move, and the rubber band can be pushed away from the support rod 240 by the second pressure plate 320.
[0043] Furthermore, the pressure plate assembly 300 also includes a first driving device 360 and a guide structure. The first driving device 360 is used to drive the second pressure plate 320 to move in a direction away from the bottom plate 100 so that the stretched rubber band can be separated from the support rod 240; the guide structure is used to guide the movement of the second pressure plate 320 during the movement of the second pressure plate 320. In the embodiment in which the first pressure plate 310 and the second pressure plate 320 are fixedly connected, the guide structure can be connected to only one of the first pressure plate 310 and the second pressure plate 320, or can be connected to both the first pressure plate 310 and the second pressure plate 320. It is not difficult to understand that the guiding direction of the guide structure is consistent with the extension direction of the support rod 240, so that the reciprocating motion of the second pressure plate 320 under the action of the first driving device 360 is smoother.
[0044] In some embodiments, Figure 1As shown, the first driving device 360 is a cylinder, the piston rod of the cylinder is fixedly connected to the first pressing plate 310, the guide structure includes a guide column 351 and a guide sleeve 352 that cooperate with each other, the guide sleeve 352 is fixed to the bottom plate 100, and the guide column 351 is fixed to the first pressing plate 310. Of course, in some other embodiments, existing devices such as a hydraulic cylinder and an electric push rod can also be used as the first driving device 360; the cylinder body of the cylinder is fixedly connected to the first pressing plate 310, the piston rod is fixedly connected to the bottom plate 100; the guide sleeve 352 is fixed to the first bottom plate 100 and the second bottom plate 100, and the guide column 351 is fixed to the bottom plate 100.
[0045] exist Figure 1 In the embodiment shown, there are four support rod assemblies 200, which are distributed along the circumference, and further, the support rods 240 slide along the radial direction almost parallel to the circumference. In other embodiments, the number of support rod assemblies 200 can also be three, five, or other numbers, as long as the rubber band can be well stretched by the support rods 240 so that the stretched rubber band can be put on the workpiece to be tied.
[0046] Furthermore, the support rod assembly 200 further includes a second driving device 210 connected to the base plate 100, and the second driving device 210 is connected to the support rod 240 in the driving support rod assembly 200, so as to drive the support rod 240 to slide relative to the said slide and thus stretch the rubber band. Further, the support rod assembly 200 further includes a guide rail 230 and a slider 220 that are slidably connected, the support rod 240 is connected to the slider 220, and the guide rail 230 is installed on the base plate 100. The output end of the second driving device 210 is connected to the slider 220, and then connected to the support rod 240. In the embodiment where only one support rod 240 is connected to each slider 220, each support rod 240 can slide along the radial direction of the circumference; further, the support rod 240 can also be directly connected to the output end of the second driving device 210.
[0047] In some embodiments, the second driving device 210 may be a pneumatic cylinder. In other embodiments, the second driving device 210 may be an existing device such as a hydraulic cylinder or an electric push rod.
[0048] Furthermore, the present application also provides a production system, including a robotic arm and the rubber band sheathing gripper provided in the above-mentioned embodiment of the present application, wherein the free end of the robotic arm is connected to the bottom plate 100 of the rubber band sheathing gripper.
[0049] The process of using rubber bands to bundle workpieces in the production system provided by the present application includes:
[0050] S1: The robot arm drives the rubber band nesting gripper to move to the position of taking the rubber band, and the distance between the support rods 240 is relatively close. Figure 1 The center position shown;
[0051] S2: The robot arm drives the rubber band nesting gripper to move so that the support rod 240 is located inside the rubber band in the initial state;
[0052] S3: The second driving device 210 drives the support rod 240 to move away from the center position to stretch the rubber band;
[0053] S4: The robotic arm drives the support rod 240 with the rubber band to move toward the workpiece to be bundled, and then drives the second pressing plate 320 to move toward the workpiece through the first driving device 360. During this process, the rubber band on the support rod 240 is pushed toward the workpiece by the second pressing plate 320; when the rubber band is separated from the support rod 240, the rubber band shrinks and is wrapped around the workpiece.
[0054] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
