Description

Technical Field

[0001] This utility model relates to the field of feeding structure technology, specifically to an adsorption and positioning structure for feeding parts. Background Technology

[0002] In industrial processing, there is a great demand for assembling irregularly shaped parts. Due to the variety of shapes, if conventional clamping and feeding structures are used to feed them, the mechanical clamping structure is prone to excessive compression of the edges of the parts, which can lead to deformation and damage. To address this, existing technologies use electric push rods in conjunction with air pumps to adsorb and feed these parts.

[0003] Currently, the utility model patent with announcement number CN222410100U discloses a welding parts feeding nozzle assembly. This patent uses a telescopic cylinder transmission combined with negative pressure adsorption to position and transport parts, which can avoid damage to parts caused by clamping and solve the adaptation problem when positioning parts by clamping, thus improving versatility.

[0004] While the above-mentioned technical solutions can meet the requirements for adsorption and feeding of irregularly shaped parts, they still require the cooperation of telescopic cylinders to perform vertical movement, just like existing technologies. This results in a large number of electrical devices being required. During maintenance, both the telescopic cylinders and the negative pressure pump need to be maintained simultaneously, leading to a significant workload. Therefore, this application provides an adsorption and positioning structure for feeding parts to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides an adsorption positioning structure for loading parts, so as to solve the problem that the existing adsorption positioning structure for loading parts requires a large number of electrical devices when adsorbing and positioning parts.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an adsorption positioning structure for feeding parts, including a connecting frame, wherein the connecting frame is provided with a plurality of guide modules, and the guide modules are provided with a plurality of air inlet pipes; A connecting module is slidably mounted on the guiding module. The bottom of the connecting module is equipped with an air supply component that restricts the gas flow direction. The air supply component is equipped with an adsorption module that adsorbs and positions the components. The connecting module includes an L-shaped component that is slidably connected to the outside of the guide module. The L-shaped component is provided with a connecting pipe and a piston component. The connecting pipe is connected to the inside of the corresponding air intake pipe through the inside of the guide module. The guide module is provided with a sliding cavity for the piston to slide, and the sliding cavity is connected to the interior of the corresponding intake pipe; The adsorption module is connected to the inside of the connecting pipe through a corresponding gas supply component.

[0007] Through the above technical solution, gas is delivered to the sliding chamber through the air inlet pipe, which can drive the piston rod to move, thereby moving the L-shaped part; at the same time, the gas can be delivered to the adsorption module through the connecting pipe normally. During the gas extraction, the adsorption module can directly adsorb the parts, and by drawing negative pressure, it can drive the piston rod to move, thereby moving the L-shaped part, realizing the same gas delivery equipment to drive two working processes.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the guide module includes a fixing block disposed on the connecting frame, the fixing block having a guide hole with an open bottom on its front side, and a guide strip disposed inside the guide hole.

[0011] Furthermore, the L-shaped component includes a sliding block that is slidably connected within the guide hole and located outside the guide strip, and a connecting block fixed to the bottom of the sliding block.

[0012] The above technical solution enables the sliding block to slide within the guide hole and is restricted by the guiding action of the guide strip.

[0013] Furthermore, the top of the fixed block is provided with two air supply holes that communicate with the interior of the corresponding air inlet pipe, and the sliding cavity is opened inside the fixed block and communicates with the interior of one of the air supply holes; The piston assembly includes a piston block slidably connected within a sliding cavity, and a piston rod fixed to the bottom of the piston block, with the outer side of the piston block fitting against the inner wall of the sliding cavity.

[0014] The above technical solution allows the intake pipe to connect with the inside of the sliding chamber through the air delivery hole, thereby driving the piston block to move within the sliding chamber.

[0015] Furthermore, a connecting groove is provided on the connecting block, a first elastic element is provided in the connecting groove, and an extrusion plate is provided on the outside of the piston rod at the top of the first elastic element; The piston rod has a plug that passes through the fixing block and the connecting block in sequence at its bottom end. The piston rod is located inside the first elastic element, and the top of the plug abuts against the bottom of the connecting block.

[0016] Through the above technical solution, the first elastic element can play the role of elastic limiting, and the plug can drive the connecting block to rise.

[0017] Furthermore, the connecting pipe is located at the top of the connecting block and is slidably connected to the inside of the corresponding air supply hole. Both ends of the connecting pipe are open. The bottom of the connecting block has a mating groove that communicates with the inside of the connecting pipe. The cross-section of the mating groove is a trapezoid that is narrower at the top and wider at the bottom.

[0018] The above technical solution allows the docking groove to be connected to the corresponding air outlet through a connecting pipe.

[0019] Furthermore, the air supply component includes a mounting block detachably connected to the bottom of the connecting block. The top of the mounting block has a movable hole for the plug to move, and the top of the mounting block has an air supply groove that communicates with the inside of the docking groove. The inner diameter of the air supply groove is equal to the inner diameter of the bottom of the docking groove. A sealing ring is provided between the mounting block and the connecting block on opposite sides, and the sealing ring is located outside the air supply groove.

[0020] The above technical solution connects the inside of the docking groove with the inside of the air supply groove, and the sealing ring can seal the connection between the two.

[0021] Furthermore, the mounting block is provided with an air supply chamber and a connecting chamber, and the interior of the air supply chamber and the air supply groove are connected to the interior of the connecting chamber.

[0022] The above technical solution allows airflow to move within the air delivery chamber, connecting chamber, and air delivery slot.

[0023] Furthermore, the adsorption module includes three adsorption cylinders located at the bottom of the mounting block and connected to the interior of the air delivery chamber. A delivery pipe is slidably connected inside the adsorption cylinder, and the interior of the delivery pipe is connected to the interior of the adsorption cylinder.

[0024] The above technical solution enables the gas delivery chamber to transport the gas from the adsorption cylinder and the delivery pipe.

[0025] Furthermore, the bottom end of the conveying pipe is provided with an adsorption nozzle that communicates with its interior. A second elastic element is provided between the top of the adsorption nozzle and the bottom of the corresponding adsorption cylinder. The second elastic element is located on the outside of the corresponding conveying pipe. Both the first elastic element and the second elastic element can be compression springs.

[0026] The above technical solution allows for the adhesion and adsorption of parts to the surface via the suction nozzle, while the second elastic element provides elastic limiting.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. With the use of a single air pump, the connecting module can be moved under the guidance of the airflow and through the cooperation between structures; and through the cooperation of the internal channels of the air supply component, the delivered gas can flow normally, thereby allowing the adsorption module to properly adsorb and position the parts, achieving the effect of vertical movement and adsorption positioning. 2. Because a single air pump is used, negative pressure can be generated in the gas flow channel during air intake, allowing the adsorption of the adsorption module and the movement of the connection module to occur simultaneously, thus optimizing the adsorption positioning process; this further improves the overall efficiency, enabling the adsorbed components to be transferred quickly, and the overall structure is simple, requiring only maintenance and repair of the gas delivery equipment.
