Description

Technical Field

[0001] The invention relates to the technical field of punching product processing, and in particular to a fully automatic loading and unloading device for punching products. Background Art

[0002] The fully automatic loading and unloading equipment for punching and cutting products is a highly efficient and automated production equipment. It can automatically complete the loading, positioning and unloading of materials during the punching and cutting process, greatly improving production efficiency and product quality.

[0003] Traditionally, the loading and unloading of punching products is completed by a mechanical arm. In order to facilitate the quick placement of punching products, a vacuum suction cup is generally used to suck the punching products.

[0004] However, the suction cups on traditional suction cup jigs are fixed, which makes it inconvenient to adjust the position of the suction heads. The spacing between the suction heads is too small, so when sucking and fixing punching products with a large surface area, they are prone to falling due to the shift of the center of gravity. The spacing between the suction heads is too small, so when sucking and fixing punching products with a small surface area, the suction heads may not be able to fully fit on the surface of the punching products, reducing the suction stability of the entire suction cup jig. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a fully automatic loading and unloading equipment for punching products, which can effectively solve the problem of the inconvenience of using the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] Furthermore, a rotating motor is installed in the mounting seat, an output end of the rotating motor is connected to a rotating tube, and a main gear is vertically fixedly installed at one end of the rotating tube away from the rotating motor.

[0010] Furthermore, the outer ring wall of the main gear is meshed with and installed with several sub-gears at the same time, and the outer ring walls of several sub-gears are meshed with and installed with a bent rod rack, and the ends of several bent rod racks are vertically fixed with moving cylinders, and several suction heads are respectively installed on the corresponding ends of the moving cylinders.

[0011] Furthermore, a plurality of sliding holes are formed on the surface of the baffle plate through the inner cavity, and a plurality of the moving cylinders are respectively and adaptively slidably installed in the corresponding sliding holes.

[0012] Furthermore, the input end of the air pump is connected to a bent pipe, a sleeve is installed on the top of the bent pipe, and the rotating tube rotates and penetrates the sleeve.

[0013] Furthermore, the cleaning assembly also includes a connector fixedly installed in the baffle, one end of the connector is connected to the rotating tube, and an exhaust pipe is connected between the connector and the plurality of movable cylinders.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] Embodiment 1:

The working principle of the four-axis robot arm 1 is based on the motor drive and the controller adjusting the current size. It is first connected to a power supply, and the controller adjusts the current size to control the movement of the robot arm. The power supply sends electrical energy to the driver and converts it into electronic force, and then converts the electronic force into mechanical force to move the robot arm. The movement of the robot arm is determined by the controller, which is usually controlled by a computer. In addition, the four-axis robot arm 1 has a sensing function, which can detect environmental changes by itself and automatically make adjustments to achieve accurate grasping and precise placement;

[0037] A baffle plate 3 is fixedly mounted at one end of the mounting base 2, and a number of suction heads 27 are slidably mounted on the surface of the baffle plate 3, and can synchronously extend and slide to adjust the distance between the baffle plate 3 and the center of the baffle plate 3. The cleaning component includes a nozzle 52 installed in the center of the baffle plate 3, and also includes an air pump 41 installed at the bottom of the mounting base 2. The input end of the air pump 41 is connected to the four suction heads 27, and the output end is connected to the nozzle 52. While the air pump 41 draws external air through the suction heads 27, it will discharge excess air through the nozzle 52, thereby completing the blow cleaning of the punching and cutting products and the punching and cutting molds while completing the adsorption and fixation of the punching and cutting products.

[0038] Embodiment 2:

[0039] Reference Figure 1-7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a fixed seat is installed at the output end of the four-axis robot arm 1, a telescopic cylinder is vertically fixedly installed on one side of the fixed seat, the output end of the telescopic cylinder passes through the fixed seat and is connected to the mounting seat 2, a rotating motor 21 is installed in the mounting seat 2, the output end of the rotating motor 21 is connected to a rotating tube 22, a main gear 23 is vertically fixedly installed at one end of the rotating tube 22 away from the rotating motor 21, the outer ring wall of the main gear 23 is simultaneously meshed with a plurality of sub-gears 24, and the outer ring walls of the plurality of sub-gears 24 are all meshed A bent rod rack 25 is installed, and the ends of several bent rod racks 25 are vertically fixed with moving cylinders 26, and several suction heads 27 are respectively installed at the corresponding ends of the moving cylinders 26. The surface of the baffle plate 3 is provided with several sliding holes 31 through the inner cavity. Several moving cylinders 26 are respectively slidably installed in the corresponding sliding holes 31. Several positioning shafts are fixedly installed in the inner cavity of the baffle plate 3, and several sub-gears 24 are rotatably installed with the corresponding positioning shafts, to ensure that in the process of adjusting the position of the moving cylinder 26, the sub-gear 24 remains stable and is not easy to shake or even fall off.

[0040] The remaining structures are the same as those of Example 1.

[0041] Embodiment 3:

[0042] Reference Figure 1-7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the input end of the air pump 41 is connected to a curved pipe 42, a sleeve 43 is installed on the top of the curved pipe 42, the rotating pipe 22 rotates and passes through the sleeve 43, the cleaning component also includes a connector 5 fixedly installed in the baffle 3, one end of the connector 5 is connected to the rotating pipe 22, and an exhaust pipe 51 is connected between the connector 5 and the plurality of moving cylinders 26. The inner tube wall of the sleeve 43 is provided with a plurality of first air holes connected to the inner cavity of the curved pipe 42, and the outer tube wall of the rotating tube 22 passes through the inner tube wall and is provided with a plurality of second air holes connected to the first air holes. Therefore, no matter how the rotating tube 22 rotates to any angle, it can maintain a connected state with the sleeve 43, and the end of the rotating tube 22 away from the rotating motor 21 is designed to be open, which is just connected to one end of the connector 5.

[0043] The input end of the air pump 41 is connected to the corresponding suction head 27 through the bent pipe 42, the sleeve 43, the rotating tube 22, the connector 5, the exhaust pipe 51 and the movable cylinder 26. An exhaust pipe is also connected between the output end of the air pump 41 and the connector 5. The exhaust pipe is embedded in the mounting seat 2 and the baffle 3, and the exhaust pipe is connected to the nozzle 52 through the connector 5. The connector 5 is not only provided with an air passage connected to several exhaust pipes 51, but also embedded with a built-in pipe, one end of which is connected to the exhaust pipe, and the other end is connected to the nozzle 52.

[0044] The remaining structure is the same as that of Example 2.

[0045] Working principle of the present invention:

[0046] In the first step, the four-axis robot arm is started to drive the fixed seat, the telescopic cylinder and the mounting seat 2 to move to the material taking position, and then the spacing between the plurality of suction heads 27 is adjusted according to the surface area of ​​the punched product to be loaded. Specifically, the rotating motor 21 is started to drive the main gear 23 to rotate through the rotating tube 22, thereby meshing and driving the plurality of sub-gears 24 to rotate synchronously, and then meshing and driving the corresponding bent rod rack 25, and finally driving the corresponding moving cylinder 26 to slide in the corresponding sliding hole 31, thereby synchronously adjusting the positions of the plurality of suction heads 27;

[0047] In the second step, the air pump 41 is started again to extract the air near the suction head 27 through the curved pipe 42, the sleeve 43, the rotating pipe 22, the connecting head 5, the suction pipe 51 and the moving cylinder 26. At the same time, the entire mounting base 2 including the suction heads 27 is pushed by the telescopic cylinder to approach and finally fit on the surface of the punched product, and a negative pressure vacuum is formed by continuous exhaust, and finally the punched product is adsorbed and fixed on the suction heads 27;

[0048] In the third step, the punched product is placed on the punching die through the four-axis robot 1, and the air pump 41 is started again. The reverse blowing finally releases the punched product through the suction head 27 and stably places it on the punching die. After the punching is completed by the punching die, the surrounding robot arms 1 again bring several suction heads 27 close and squeeze them to fit on the surface of the punched product. By starting the air pump 41, the punched product that has been punched is adsorbed by the suction head 27 again. At the same time, the output end of the air pump 41 sprays excess air through the nozzle 52, thereby blowing and cleaning the punching die and the punched product.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
