Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a flexible pushing robotic arm for an automatic box packer. Background Technology

[0002] A case packer is a device that semi-automatically or automatically loads unpackaged or small-packaged products into transport packaging. In automated packaging lines, the case packer is the core equipment of the entire system. Although it is not a machine that directly produces products, it is an important component for achieving production automation. Case packers are widely used in the food, beverage, pharmaceutical, and daily chemical industries, primarily for ensuring product quality and safety and improving production efficiency. Its working process typically includes carton forming, product arrangement and packing, and sealing. The robotic pusher of the case packer is a key component of the automated case packing system. It is mainly responsible for pushing products into the packaging boxes, and this pushing action improves packing efficiency. Compared to manual placement or simple feeding, the robotic pusher can quickly and accurately deliver products into the boxes, significantly shortening packing time and meeting the needs of high-speed production lines, as follows.

[0003] A search revealed patent CN119038152B, which discloses a material-pushing robot, relating to the field of robotic arm technology. The robot includes an arm base; a wide-plate pushing assembly; and a length adjustment assembly arranged sequentially from top to bottom on the same side wall of the arm base. The wide-plate pushing assembly includes a bidirectional telescopic cylinder mounted on the side wall of the arm base, with an adjustment bracket mounted on the piston rod of each cylinder. The length adjustment assembly includes a pushing cylinder mounted on the side wall of the arm base, with a fixed seat mounted on the piston rod. Adjusting rods are movably embedded on both sides of the fixed seat near the adjustment brackets, and the two adjusting rods are slidably mounted on the two adjustment brackets. An adjustment seat is hinged to the side of the fixed seat away from the pushing cylinder via a torsion spring-loaded pivot, and a pushing head is movably mounted on the adjustment seat. This invention offers advantages such as improved stability during material pushing, increased production efficiency, and enhanced safety.

[0004] However, the aforementioned pusher robot still has the following areas for improvement. For example, its height is not easy to adjust, and different production line conveyor devices have different heights. This means that after the pusher robot is installed, the distance between the pusher plate and the pusher platform of the production line conveyor device cannot be adjusted. Therefore, it cannot be applied to different production line conveyor devices, resulting in a small range of applications and poor practicality. Therefore, there is an urgent need for a flexible pusher robot for automatic box packing machines to solve the above technical problems. Utility Model Content

[0005] This utility model discloses a flexible pushing robot for an automatic box packing machine. By incorporating a lifting mechanism, the device can be mounted above the pushing platform of the production line conveyor during operation. Then, based on the actual height requirements of the pushing platform, the lifting cylinder can be activated to extend and retract, causing the lifting seat to move up and down. This, in turn, moves the sliding block and the pushing plate mechanism mounted on the sliding block up and down, adjusting the distance between the pushing plate mechanism and the pushing platform of the production line conveyor, bringing it closer to the pushing platform. This facilitates better and more accurate pushing operations, making the device applicable to various production line conveyors and greatly expanding its applicability. In summary, this invention solves the problems in the background technology.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The present invention relates to a flexible pushing robot for an automatic box packing machine, comprising a top base, the bottom of which is provided with four supporting legs;

[0008] A lifting mechanism includes a lifting electric cylinder, which is fixedly installed in a through-type manner at the top base. The telescopic end of the lifting electric cylinder is fixedly connected to a lifting seat. The bottom of the lifting seat has two first sliding grooves and one mounting groove. The mounting groove is located between the two first sliding grooves. A drive motor is fixedly installed at the top of the lifting seat. A first gear is fixedly connected to the output end of the drive motor. A ball screw is rotatably installed in the mounting groove through two bearing seats.

A slide block is slidably installed at the first sliding groove. The top of the slide block is fixedly connected to the slider. A rectangular locking groove is provided at the bottom of the slide block.

[0009] A push plate mechanism is located at the bottom of the slide.

[0010] Furthermore, each of the four support legs has a second sliding groove vertically formed on its inner side, and the outer side of the lifting seat is slidably connected to the four second sliding grooves through multiple sliding connectors.

[0011] Furthermore, the top of the slide is fitted to the bottom of the lifting seat, and the top of the slide is a smooth surface.

[0012] Furthermore, the push plate mechanism includes a push plate body and a mounting frame. A locking block is fixedly connected to the top of the push plate body. The locking block matches and engages with a locking groove. A limiting groove is formed on one side of the locking block. The mounting frame is fixedly installed on one side of the slide. A pull rod is movably connected through the mounting frame. An abutment plate is fixedly connected to one end of the pull rod. A limiting block is fixedly connected to one side of the abutment plate. The limiting block movably passes through one side of the slide and matches and engages with the limiting groove. Multiple springs are fixedly connected to the other side of the abutment plate. The other end of the springs is fixedly connected to the mounting frame.

[0013] Furthermore, both the front and rear ends of the abutment plate are in contact with the front and rear sides of the interior of the mounting frame, and both the front and rear ends of the abutment plate are smooth surfaces.

[0014] Furthermore, a rubber pad is attached and fixed to one side of the push plate body, and the rubber pad has multiple through cavities at equal intervals inside.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates a lifting mechanism, allowing the device to be mounted above the pushing platform of the production line conveyor during operation. The lifting mechanism can then adjust the distance between the pushing plate mechanism and the pushing platform according to the actual height requirements of the production line conveyor's pushing platform, ensuring the pushing plate mechanism is close to the platform. This facilitates better and more accurate pushing operations, making the device suitable for various production line conveyors, greatly expanding its applicability and practicality.

[0017] 2. This technical solution incorporates a pusher mechanism. During operation, the drive motor, in conjunction with the first and second gears, rotates the ball screw. The rotating ball screw, in turn, engages with the first slide groove and the slider, causing the slide block to move laterally. This, in turn, moves the pusher mechanism laterally, pushing the products from the production line conveyor's pusher platform into the packaging box, completing the pushing operation. Furthermore, the pusher body can be quickly and easily disassembled and replaced according to actual needs, such as different product shapes or sizes. This allows the pusher body to be suitable for pushing products of various shapes and sizes. The ease of quick and convenient replacement and adjustment of the pusher body meets the requirements of flexible operation, further improving the practicality of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-4 The flexible pushing robot of the automatic packing machine includes a top seat 1, and the bottom of the top seat 1 is provided with four support legs 2;

[0029] The lifting mechanism 3 includes a lifting cylinder 301, which is fixedly installed through the top base 1. The telescopic end of the lifting cylinder 301 is fixedly connected to a lifting seat 302. The bottom of the lifting seat 302 has two first sliding grooves 303 and one mounting groove 304 horizontally formed, with the mounting groove 304 located between the two first sliding grooves 303. A drive motor 305 is fixedly installed on the top of the lifting seat 302, and the output end of the drive motor 305 is fixedly connected to a first gear 306. A ball screw 307 is rotatably mounted in the mounting groove 304 via two bearing seats. A slider 308 is screwed to the outside of the ball screw 307. A second gear 309 is provided at one end of the ball screw 307. The second gear 309 meshes with the first gear 306. A slide block 310 is slidably mounted at the first slide groove 303. The top of the slide block 310 is fixedly connected to the slider 308. A rectangular mounting groove 311 is provided at the bottom of the slide block 310. A push plate mechanism 4 is located at the bottom of the slide block 310.

[0030] The inner sides of the four support legs 2 are vertically provided with second slide grooves 5, and the outer side of the lifting seat 302 is slidably connected to the four second slide grooves 5 through multiple sliding connectors; the top of the slide 310 fits against the bottom of the lifting seat 302, and the top of the slide 310 is a smooth surface.

[0031] In the specific implementation process, during operation, the device can be set up above the pushing platform of the production line conveyor. Then, according to the actual height requirements of the pushing platform of the production line conveyor, the lifting cylinder 301 can be activated to extend and retract, driving the lifting seat 302 to move up and down, thereby driving the slide 310 and the push plate mechanism 4 installed at the slide 310 to move up and down. The distance between the push plate mechanism 4 and the pushing platform of the production line conveyor can be adjusted so that it is close to the pushing platform of the production line conveyor, which facilitates better and more accurate pushing work in the future. Thus, the device can be applied to a variety of different production line conveyors, greatly improving the applicability of the device.

[0032] The inner sides of the four support legs 2 are vertically provided with second slide grooves 5, and the outer side of the lifting seat 302 is slidably connected to the four second slide grooves 5 through multiple sliding connectors in order to improve the overall stability of the lifting seat 302.

[0033] The top of the slide 310 is attached to the bottom of the lifting seat 302 to improve the overall stability of the slide 310, while the top of the slide 310 is a smooth surface to reduce the friction and wear between the slide 310 and the lifting seat 302. Specific Implementation Example 2:

[0035] Reference Figure 4 and Figure 5 In a preferred embodiment, the push plate mechanism 4 includes a push plate body 401 and a mounting bracket 402. A locking block 403 is fixedly connected to the top of the push plate body 401. The locking block 403 matches and engages with the locking groove 311. A limiting groove 404 is provided on one side of the locking block 403. The mounting bracket 402 is fixedly installed on one side of the slide block 310. A pull rod 405 is movably connected through the mounting bracket 402. An abutment plate 406 is fixedly connected to one end of the pull rod 405. A limiting block 407 is fixedly connected to one side of the abutment plate 406. The limiting block 407 movably passes through one side of the slide block 310 and matches and engages with the limiting groove 404. A plurality of springs 408 are fixedly connected to the other side of the abutment plate 406. The other end of the springs 408 is fixedly connected to the mounting bracket 402.

[0036] Both ends of the abutment plate 406 are in contact with the front and rear sides of the interior of the mounting bracket 402, and both ends of the abutment plate 406 are smooth surfaces; a rubber pad 409 is fixedly attached to one side of the push plate body 401, and multiple through cavities 410 are equally spaced inside the rubber pad 409.

[0037] In practical implementation, during operation, the drive motor 305, in conjunction with the first gear 306 and the second gear 309, drives the ball screw 307 to rotate. When the ball screw 307 rotates, it works in conjunction with the first slide groove 303 and the slider 308 to drive the slide block 310 to move laterally, thereby driving the push plate body 401 to move laterally, pushing the product at the pushing platform of the production line conveyor into the packaging box, completing the pushing work. Moreover, according to actual needs, such as different product shapes or sizes, the pull rod 405 can be pulled up, causing the spring 408 to compress, the abutment plate 406 to move, and driving the limit block 407 to move. Once separated from the limiting groove 404, the push plate body 401 can be quickly and easily removed for replacement. When replacing and installing a matching push plate body 401, keep the pull rod 405 pulled up, and match and engage the locking block 403 at the top of the push plate body 401 with the locking groove 311. Then release the pull rod 405, and the spring 408 will return, driving the abutment plate 406 and the limiting block 407 to reset until the limiting block 407 matches and engages with the limiting groove 404. This allows for quick and easy installation and locking of the push plate body 401. In summary, the push plate body 401 is easy to replace and adjust quickly and conveniently, meeting the needs of flexible operation.

[0038] The front and rear ends of the abutment plate 406 are fitted with the front and rear sides of the interior of the mounting bracket 402 to limit the position of the abutment plate 406 and improve its stability. The front and rear ends of the abutment plate 406 are smooth surfaces to reduce the friction and wear between the abutment plate 406 and the mounting bracket 402.

[0039] Among them, the rubber pad 409 can increase the friction between the push plate body 401 and the product, and can reduce the contact impact force between the push plate body 401 and the product, thus protecting the product.
