Description

Technical Field

[0001] This utility model relates to the field of electric suction cup technology, specifically to an electric suction cup that operates without stopping. Background Technology

[0002] A suction cup is a device that uses the pressure difference between the inside and outside of the atmosphere to adhere to an object, or a tool for gripping objects, to achieve stable movement of materials and facilitate subsequent processing. Early suction cups mostly used soft materials such as rubber, creating negative pressure by squeezing out internal air to achieve adhesion. They were mainly used in industries such as glass and ceramics to handle fragile products with relatively flat surfaces, solving the problems of low efficiency and easy breakage associated with manual handling. However, with the increasing demands for safety and efficiency in modern industrial handling processes, traditional suction cups could no longer meet actual production requirements. Against the backdrop of rapid technological development, electric suction cups emerged. While electric suction cups have a wider range of applications, they also have the following main drawbacks in practical use:

[0003] Most electric suction cups rely on pressure sensing elements for control. If the pressure sensing element fails or the motor malfunctions, the suction force may be insufficient, resulting in unstable workpiece adhesion or even workpiece falling and being damaged. In severe cases, this can injure the operator and pose a safety hazard during operation. Traditional electric suction cups mostly use diaphragm pumps, which are noisy in actual use. During the operation of the electric suction cup, the pump must be stopped after the pressure reaches the upper limit. Otherwise, the motor load will increase and may cause the motor to overload and burn out, affecting the service life of the electric suction cup.

[0004] Therefore, a non-stop electric suction cup is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a reasonably designed electric suction cup that does not stop, which can solve the above-mentioned defects and deficiencies of the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-stop electric suction cup, comprising: a housing, a drive structure inside the housing, a transmission component on one side of the drive structure, a plunger-type air pump on one side of the transmission component, and an adsorption component below the housing.

[0007] Preferably, the drive structure includes a motor fixedly mounted inside the housing on one side, a display screen mounted on the housing above the motor, and a switch on one side of the display screen.

[0008] Preferably, the transmission assembly includes a gearbox connected to the output end of the motor, an output shaft connected to one side of the gearbox, a crank connected to the top of the output shaft, an eccentric pin fixedly mounted on the crank, and a connecting rod connected to the eccentric pin.

[0009] Preferably, the plunger-type air pump includes a steel sleeve fixedly installed inside the housing, a reciprocating cylinder movably installed inside the steel sleeve, the input end of the reciprocating cylinder being fixedly connected to one end of a connecting rod, a spring frame being installed in the inner hole of the reciprocating cylinder, a spring being connected to the spring frame, a cylinder being connected to the output end of the reciprocating cylinder, a one-way valve being fixedly installed at the output end of the cylinder, an air pipe being connected to the output end of the one-way valve, and a battery pack being installed on the outside of the air pipe.

[0010] Preferably, a piston rod is connected inside the cylinder, a piston is fixedly mounted on one end of the piston rod, and a piston ring is fixedly mounted on the piston.

[0011] Preferably, the adsorption assembly includes a suction cup fixedly disposed at the bottom of the housing, and a sealing ring is fixedly disposed on the inner side of the suction cup.

[0012] The beneficial effects of this utility model after adopting the above structure are:

[0013] 1. The drive structure and transmission components in the non-stop electric suction cup work continuously, and the electric suction cup will continue to adsorb without stopping. This ensures that the electric suction cup is always stable within the required pressure range during operation, thereby avoiding unstable adsorption of workpieces or even falling and being damaged, and improving the working efficiency of the electric suction cup.

[0014] 2. The reciprocating cylinder moves back and forth under the drive of the motor. After the suction cup is started, the motor works until the pressure value is reached and then runs without load. When the pressure drops, the motor will continue to rotate, ensuring that the motor will not burn out due to overload when it is working continuously. This effectively improves the practicality of the electric suction cup that does not stop. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figure 1 - Figure 2 As shown, the non-stop electric suction cup includes a housing 1, a drive structure 2 is provided inside the housing 1, a transmission component 3 is provided on one side of the drive structure 2, a plunger-type air pump 4 is provided on one side of the transmission component 3, and an adsorption component 5 is provided below the housing 1.

[0025] The drive structure 2 includes a motor 21 fixedly installed inside one side of the housing 1, a display screen 22 mounted on the housing 1 above the motor 21, and a switch 23 on one side of the display screen 22.

[0026] The transmission assembly 3 includes a gearbox 31 connected to the output end of the motor 21. An output shaft 32 is connected to one side of the gearbox 31. A crank 33 is connected to the top of the output shaft 32. An eccentric pin 34 is fixedly mounted on the crank 33. A connecting rod 35 is connected to the eccentric pin 34.

[0027] As an optimized solution of this utility model, the drive structure 2 and transmission component 3 of the non-stop electric suction cup work continuously, and the adsorption component 5 will continue to adsorb while the drive structure 2 is running, ensuring that the electric suction cup is always stable within the required pressure range during operation, thereby avoiding unstable adsorption of the workpiece or even falling and being damaged, improving the safety of the electric suction cup, and at the same time improving the working efficiency of the electric suction cup.

[0028] See Figure 3 - Figure 6 As shown, the plunger-type air pump 4 includes a steel sleeve 41 fixedly installed inside the housing 1. A reciprocating cylinder 42 is movably installed inside the steel sleeve 41. The input end of the reciprocating cylinder 42 is fixedly connected to one end of the connecting rod 35. A spring frame 43 is installed in the inner hole of the reciprocating cylinder 42. A spring 44 is connected to the spring frame 43. A cylinder 45 is connected to the output end of the reciprocating cylinder 42. A one-way valve 46 is fixedly installed at the output end of the cylinder 45. An air pipe 47 is connected to the output end of the one-way valve 46. A battery pack 48 is installed on the outside of the air pipe 47.

[0029] A piston rod 451 is connected inside the cylinder 45, a piston 452 is fixedly installed at one end of the piston rod 451, and a piston ring 453 is fixedly installed on the piston 452.

[0030] The adsorption assembly 5 includes a suction cup 51 fixedly disposed at the bottom of the housing 1, and a sealing ring 52 is fixedly disposed on the inner side of the suction cup 51.

[0031] As an optimized solution of this utility model, the reciprocating cylinder 42 in the plunger-type air pump 4 reciprocates under the drive of the motor 21. After the suction cup 51 is started, the motor 21 works until the pressure reaches the standard value and then runs without load. When the pressure drops, the motor 21 will continue to rotate, ensuring that the motor 21 will not burn out due to overload when it works continuously, which effectively improves the practicality of the electric suction cup that does not stop.

[0032] The usage process of this utility model:

[0033] The drive structure 2 and transmission component 3 of the non-stop electric suction cup will continue to work, and the suction component 5 will continue to suction without stopping, ensuring that the electric suction cup remains stable within the required pressure range during operation. This avoids unstable suction of the workpiece or even dropping and damage, improving the safety of the electric suction cup and increasing its working efficiency. To use the non-stop electric suction cup, first place the suction cup 51 on the workpiece to be moved, close the switch 23, and the battery pack 48 outside the air pipe 47 continuously supplies power to the motor 21. The output end of the motor 21 is connected to a gearbox 31, and the output end of the gearbox 31 is connected to an output shaft 32. The output shaft 32 receives the rotational torque of the motor 21 through the gearbox 31, and then... Output shaft 32 transmits power to crank 33. An eccentric pin 34 is fixedly mounted on crank 33, and a connecting rod 35 is connected to the eccentric pin 34. When crank 33 starts to rotate, it drives the eccentric pin 34 to rotate. The rotation of the eccentric pin 34 drives the connecting rod 35 to move, causing the reciprocating cylinder 42 to reciprocate. The reciprocating cylinder 42 is movably mounted inside the steel sleeve 41 in the housing 1. The connecting rod 35 drives the reciprocating cylinder 42 to move to the right. At this time, the reciprocating cylinder 42 pushes the spring frame 43, which is located in the inner hole of the reciprocating cylinder 42, to move. The spring frame 43 compresses the spring 44 to store energy, simultaneously pushing the piston 452. The piston rod 451 and piston ring 453 move to the right simultaneously in the cylinder 45. At this time, the one-way valve 46 is closed. When the piston ring 453 exhausts to the rightmost end... Figure 5As shown, after reaching the rightmost end, connecting rod 35 drives reciprocating cylinder 42 to begin moving to the left. At this time, spring 44 releases its stored energy, driving spring frame 43 and piston rod 451 to move to the left. One-way valve 46 opens, and piston ring 453 forms a sealed space with cylinder 45. Air is drawn out from the sealed space between the sealing ring 52 in suction cup 51 and the workpiece surface through air pipe 47, creating a negative pressure state. After several cycles, the suction continues, and the negative pressure increases until it meets the working requirements. At this point, suction cup 51 meets the adsorption requirements, thus achieving the workpiece handling capability. The purpose is to ensure that the motor 21 does not need to stop after the required pressure value is reached. A large negative pressure is generated in the cylinder 45, keeping the spring 44 stationary at the far right. At this time, the motor 21 is in an unloaded state. When the pressure on the suction cup 51 decreases, the spring force exceeds the negative pressure inside the piston 452, causing the spring 44 to move to the left. Simultaneously, the reciprocating cylinder 42 continuously reciprocates, compressing the spring 44 again to return the negative pressure to the required value. The plunger-type air pump 4 effectively ensures that the motor 21 will not burn out due to overload during continuous operation, effectively improving the practicality of the non-stop electric suction cup. It should be understood that the above specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
