Description

Technical Field

[0001] This invention relates to the field of carbon fiber prepreg packaging technology, and in particular to a robotic arm and clamping device for packaging carbon fiber prepreg products. Background Technology

[0002] In the field of carbon fiber prepreg packaging production, robotic arms are the core equipment for achieving automated packaging. They need to simultaneously complete a series of operations such as product clamping, packaging material conveying, and cutting.

[0003] Existing packaging robotic arms generally suffer from low functional integration. The gripping mechanism is independent of the packaging and cutting mechanisms, resulting in large equipment space occupation and cumbersome operation procedures. Some existing robotic arms lack sufficient flexibility in steering adjustment, making it difficult to adapt to the packaging needs of different product specifications during the packaging process. Furthermore, the gripping mechanism does not provide adequate protection for the product, making it prone to product slippage or surface damage. In addition, existing robotic arms have insufficient stability in conveying packaging materials, and the cutting mechanism has poor ease of disassembly and maintenance, affecting overall packaging efficiency and equipment lifespan.

[0004] To address the aforementioned issues, this invention proposes an integrated, highly flexible, and protective robotic arm and gripping device for packaging carbon fiber prepreg products. Summary of the Invention

[0005] The purpose of this invention is to provide a robotic arm and gripping device for packaging carbon fiber prepreg products, which solves the problems of low functional integration, insufficient steering adjustment, and poor gripping effect of existing robotic arms.

[0006] To achieve the above objectives, the present invention provides a robotic arm for packaging products, comprising a base, a threaded rod, a steering column, and a processing frame. The steering column is threadedly connected to the threaded rod via a connecting ring. Mounting arms are provided on both the front and rear sides of the steering column. The processing frame has a beveled edge on its lower front side. The processing frame is fixedly mounted on the lower side of one of the mounting arms, and a packaging motor is provided on its side. A roller is provided at the output end of the packaging motor, and the roller is located inside the processing frame. A cutting blade is provided on the back side of the processing frame.

[0007] The cutting blade is positioned with its blade facing downwards and is detachable.

[0008] The length of the roller is less than the inner width of the processing frame, and its surface is coated with an anti-slip material.

[0009] The steering column is hollow inside, and a steering motor is installed at its bottom. The output end of the steering motor is connected to a top seat through a drive rod.

[0010] The top seat fits perfectly over the upper end of the steering column and can rotate freely at the upper end of the steering column.

[0011] A work light is provided on the upper side of the top seat.

[0012] Each of the mounting arms includes a support arm body, an electric cylinder, a mounting frame, an adjusting motor, an adjusting wheel, and a driven disc. The driven disc is rotatably disposed on the inner bottom side of the mounting frame and meshes with the gear of the adjusting wheel. The adjusting gear is fixed to the output end of the adjusting motor and is located inside the mounting frame. The adjusting motor is fixedly disposed on one side of the mounting frame. The mounting frame is fixedly disposed on the output end of the electric cylinder. The electric cylinder is fixedly disposed on the lower side of the outer end of the support arm body.

[0013] One end of the threaded rod is fixed to the output end of the movable motor fixedly installed at the bottom of the base, and the upper side of the connecting ring on its periphery is fixedly connected to the movable disk at the lower end of the steering column. The movable disk is provided with movable wheels on both sides of its lower side.

[0014] The present invention also provides a clamping device for packaging products, which can be applied to any of the above-mentioned robotic arms for packaging products. It includes a support plate and two clamping rods rotatably disposed on both sides of the support plate. The clamping rods have an arc-shaped structure. The support rods are fixedly disposed on the lower side of the support arm body without the processing frame installed. An auxiliary rod is provided on one side of the clamping rods. A clamping pad and a limiting block are provided at the lower end of the clamping rods.

[0015] The limiting block is fixedly connected to the clamping rod, the clamping pad is rotatably connected to the clamping rod, and the limiting block is located on the back side of the clamping pad.

[0016] The present invention provides a robotic arm and gripping device for packaging carbon fiber prepreg products, the advantages of which are as follows: 1. The steering motor drives the top seat to rotate through the drive rod. Combined with the horizontal movement structure driven by the threaded rod, it can realize multi-directional and high-precision adjustment of the robotic arm to adapt to the packaging needs of products of different specifications. The packaging motor drives the roller to roll the product and also press the transparent tape on the outside of the product packaging box. Then, the adjustment motor drives the adjustment wheel to rotate, thereby adjusting the deflection posture of the processing frame so that the cutting blade can cut the transparent tape. The steering is flexible and highly integrated. 2. The arc-shaped clamping rod, combined with the rotatable clamping pad, can conform to the product surface. The auxiliary rod can prevent the product from slipping and effectively avoid damage to the product surface. The limiting block holds the back of the clamping pad to prevent the clamping surface of the clamping pad from being parallel to the base and not being able to reset in time. This would prevent the clamping surface from conforming to the surface of the item and affect subsequent clamping use. Attached Figure Description

Detailed Implementation

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] Please see Figures 1-4 ,in Figure 1 This is a schematic diagram of the overall structure of a robotic arm for packaging products according to the present invention. Figure 2 This is the invention Figure 1 Enlarged view of the local structure at point A. Figure 3 This is a front view of a robotic arm for packaging products according to the present invention. Figure 4 This is the invention Figure 3 BB line section view.

[0027] This invention provides a robotic arm for packaging products, comprising a base 101, a threaded rod 102, a steering column 103, and a processing frame 104. The steering column 103 is threadedly connected to the threaded rod 102 via a connecting ring 105. Mounting arms 106 are provided on both the front and rear sides of the steering column 103. The processing frame 104 has a beveled edge 107 on its lower front side. The processing frame 104 is fixedly mounted on the lower side of one of the mounting arms 106, and a packaging motor 108 is provided on its side. A roller 109 is provided at the output end of the packaging motor 108. The roller 109 is located inside the processing frame 104, and the length of the roller 109 is less than that of the processing frame 104. The inner width of the 04 is coated with an anti-slip material. A cutting blade 110 is provided on the back side of the processing frame 104. The cutting blade 110 has a downward blade and is detachable. Specifically, it should be noted that the anti-slip material on the surface of the roller 109 can enhance the friction with the packaging material and avoid slippage during transportation. The inclined side 107 is designed to expose the main area of ​​the roller 109 after the processing frame 104 is deflected, preventing the cutting blade 110 and the roller 109 from being on the same plane during operation, which would affect product packaging. The cutting blade 110 adopts a detachable design, which facilitates later replacement and maintenance and extends the overall service life of the equipment.

[0028] Furthermore, the steering column 103 is hollow inside, and a steering motor 111 is provided at its bottom. The output end of the steering motor 111 is connected to a top seat 113 through a drive rod 112. The top seat 113 fits perfectly over the upper end of the steering column 103 and can rotate freely on the upper end of the steering column 103. A work light 114 is provided on the upper side of the top seat 113. Specifically, the work light 114 is in a red state after the robotic arm mechanism is started and in a green state when stationary. The top seat 113 rotates freely with the steering column 103 through a bearing and provides mounting connection support for the two mounting arms 106. Ventilation holes are also provided on the periphery of the steering column 103 to ensure that its internal temperature does not become too high.

[0029] Furthermore, each mounting arm 106 includes a support arm body 115, an electric cylinder 116, a mounting frame 117, an adjusting motor 118, an adjusting wheel 119, and a driven disk 120. The driven disk 120 is rotatably disposed on the inner bottom side of the mounting frame 117 and meshes with the adjusting wheel 119. The adjusting gear is fixed to the output end of the adjusting motor 118 and located inside the mounting frame 117. The adjusting motor 118 is fixedly disposed on one side of the mounting frame 117. The mounting frame 117 is fixedly disposed on the output end of the electric cylinder 116. The electric cylinder 116 is fixedly disposed on the lower side of the outer end of the support arm body 115. Specifically, the support arm body 115 provides mounting support for the electric cylinder 116. The electric cylinder 116 adjusts the vertical height of the mounting frame 117. The adjusting motor 118 drives the adjusting wheel 119 to rotate, thereby driving the driven disk 120 to rotate and adjusting the deflection posture of the processing frame 104 to achieve multi-directional angle adjustment.

[0030] Furthermore, one end of the threaded rod 102 is fixed to the output end of the moving motor 121, which is fixedly installed at the bottom of the base 101. The upper side of the connecting ring 105 on its periphery is fixedly connected to the moving disk 122 at the lower end of the steering column 103. The moving disk 122 is provided with moving wheels 123 on both sides of its lower side. Specifically, the threaded rod 102 rotates under the drive of the moving motor 121, thereby adjusting the longitudinal movement of the moving disk 122 and the steering column 103 on the base 101, expanding the working area, reducing the number of equipment required, and reducing costs. The two moving wheels 123 further support the moving disk 122 and the steering column 103, reduce the gravity between the connecting ring 105 and the threaded rod 102, and facilitate the movement of the moving disk 122.

[0031] In this embodiment, during use, the threaded rod 102 drives the connecting ring 105 and the moving disk 122 to move longitudinally on the base 101 under the action of the moving motor 121, and moves to the target position. At this time, the working light 114 is red. After starting the steering motor 111 and driving the drive rod 112, adjust the deflection angle of the top seat 113 and the support arm body 115 so that they can move within the circumference of the steering column 103. Start the electric cylinder 116 and adjust the motor 118 to make the inclined side 107 of the processing frame 104 parallel to the surface of the packaging material, and the roller 109 fits into the packaging material to press or lay the sealing strip on the packaging material. After processing, adjust the motor 118 to drive in the opposite direction and deflect the angle of the processing frame 104 so that the cutting blade 110 cuts the sealed strip. When the electric cylinder 116 retracts the mounting frame 117, the equipment is turned off, and the work light 114 turns green.

[0032] Please see Figures 5-6 ,in Figure 5 This is a schematic diagram of the overall structure of a robotic arm and clamping device for packaging carbon fiber prepreg products according to the present invention. Figure 6 This is the invention Figure 5 Enlarged view of the local structure at point C.

[0033] The present invention also provides a clamping device for packaging products, including a support plate 201 and two clamping rods 202 rotatably disposed on both sides of the support plate 201. The clamping rods 202 have an arc-shaped structure. The support rods are fixedly disposed on the lower side of the support arm body 115 without the processing frame 104 installed. An auxiliary rod 203 is provided on one side of the clamping rod 202. A clamping pad 204 and a limiting block 205 are provided at the lower end of the clamping rod 202. The clamping pad 204 is made of rubber and has good anti-slip and deformation properties. When used in conjunction with the clamping rods 202 to clamp the packaged items, it can effectively fit the items. The auxiliary rod 203 also supports the items after the clamping rods 202 grab the items, preventing the items from detaching from the side of the clamping rods 202.

[0034] Furthermore, the limiting block 205 is fixedly connected to the clamping rod 202, and the clamping pad 204 is rotatably connected to the clamping rod 202. The limiting block 205 is located on the back side of the clamping pad 204. Specifically, the arc-shaped clamping rod 202, combined with the rotatable clamping pad 204, can conform to the product surface. The auxiliary rod 203 can prevent the product from slipping, effectively avoiding damage to the product surface. The limiting block 205 abuts against the back side of the clamping pad 204, preventing the clamping surface of the clamping pad 204 from being parallel to the base 101 with its clamping surface facing downwards. Otherwise, the clamping pad 204 cannot be reset in time, the clamping surface cannot conform to the surface of the item, and it will affect subsequent clamping use. In this embodiment, when packaging items, the support arm body 115 on the other side of the steering column 103 can be activated simultaneously. The operation steps are the same as those for adjusting the height and deflection posture of the processing frame 104. The two clamping rods 202 are adaptively adjusted according to the size and placement of the items. Before the two clamping rods 202 contact the items, the two clamping pads 204 first adhere to the items. As the two clamping rods 202 rotate, the clamping of the items becomes tighter and tighter. The clamping pads 204 always remain in contact with the items and do not change their contact posture due to the rotation of the clamping rods 202. After the clamping device clamps the product through the clamping rods 202, the packaging motor 108 drives the roller 109 to rotate, conveying packaging materials to wrap the product. After wrapping, the packaging material is cut by the cutting blade 110, realizing automated packaging operation.
