[0001] This utility model relates to the field of robotic arm technology, specifically a robotic arm for picking up bottle cap injection molded parts. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Injection molding machines are the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through injection molding machines and molds. When producing bottle cap injection molded parts, after injection molding is completed, a part removal process is required. In order to improve the efficiency of part removal, a part removal robot is often used to replace manual part removal.

[0024] 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.

[0025] Example 1: Please refer to Figures 1 to 4 This embodiment provides a technical solution: a bottle cap injection molding part picking robot, including a movable seat 4 and a gripping mechanism 2. The gripping mechanism 2 is located at the bottom end of the movable seat 4. The gripping mechanism 2 includes an electric push rod 203 located at the bottom end of the movable seat 4. The electric push rod 203 reduces the speed and increases the torque through a built-in motor-driven reduction mechanism, which can convert the rotational motion of the motor into the linear reciprocating motion of the push rod. During the movement, a linear guide rail or guide rod provides high-precision guidance to ensure that the push rod runs smoothly in the predetermined direction. At the same time, the stroke control is realized through limit switches or sensors. When selecting, the appropriate model should be selected according to the actual needs. All the components required in the electric push rod 203 are existing technologies and will not be described in detail below.

[0026] The output end of the electric push rod 203 is equipped with a movable plate 202. Both ends of the movable plate 202 have accessory boxes 201. The bottom of the accessory box 201 contains the suction pump body 206. Based on fluid mechanics principles, the suction pump body 206 achieves gas transfer by changing the pump chamber volume through mechanical movement. When the motor drives the eccentric wheel or piston to rotate at high speed, the pump chamber volume changes periodically: during the volume increase phase, the internal pressure is lower than the external atmospheric pressure, the inlet check valve opens, and air flows into the pump chamber through the inlet; during the volume decrease phase, the gas is compressed, the pressure increases, causing the exhaust check valve to open, and the gas is discharged from the exhaust port. This process continues to cycle, forming a stable negative pressure at the inlet, which can be used to adsorb lightweight objects such as bottle caps. By adjusting the motor speed or changing the pump chamber structure, the suction flow rate and negative pressure intensity can be precisely controlled to adapt to different working conditions. When selecting a pump body 206, the appropriate model should be chosen according to actual needs. All components required within the suction pump body 206 are existing technologies and will not be described further below.

[0027] Two sets of suction pump bodies 206 are provided, which are symmetrically distributed about the electric push rod 203. The input end of the suction pump body 206 is provided with a suction pipe 204. The two ends of the bottom of the movable plate 202 are evenly provided with suction ports 205. The end of the suction pipe 204 away from the suction pump body 206 is connected to the suction port 205. The top of the accessory box 201 is provided with an air outlet. The inside of the movable plate 202 is provided with a ventilation groove, and the suction ports 205 are evenly arranged below the ventilation groove.

[0028] The overall effect of Embodiment 1 is as follows: The electric push rod 203 pushes the movable plate 202 downwards, moving the suction port 205 above the bottle cap. The suction pump body 206 generates suction, creating a stable negative pressure space at the bottom of the suction port 205. The suction port 205 is made of elastic silicone to ensure a tight seal during suction. After the bottle cap is injection molded and cooled, the negative pressure suction overcomes the weight of the bottle cap and the adhesion force of the mold, smoothly removing it from the mold cavity.

[0029] Example 2: A threaded block 8 is provided at the top of the movable seat 4. A lead screw 5 passes through the inside of the threaded block 8. A fixed seat 1 is provided outside the lead screw 5. A protective shell 3 is provided at one end of the fixed seat 1. Heat dissipation holes are evenly distributed on the outer side of the protective shell 3. A movable groove 6 is provided at the bottom of the fixed seat 1. The lead screw 5 is rotatably disposed inside the movable groove 6. A drive motor 7 is provided inside the protective shell 3. The drive motor 7 works on the principle that a current-carrying conductor moves under the force of a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. Under the action of Ampere force in the magnetic field, torque is generated, causing the rotor to rotate. At the same time, the commutator continuously changes the direction of the coil current to ensure that the rotor rotates continuously in the same direction. When selecting the drive motor 7, the appropriate model should be selected according to the actual needs. All the components required in the drive motor 7 are existing technologies and will not be described in detail below.

[0030] The output end of the drive motor 7 is connected to the lead screw 5. By using the operation of the drive motor 7, the lead screw 5 can be driven to rotate.

[0031] The effect achieved by the entire embodiment 2 is as follows: by using the operation of the drive motor 7, the lead screw 5 can be rotated, which can drive the threaded block 8 outside the lead screw 5 to move. When the bottle cap is moved above the collection device, the suction pump body 206 is then turned off. While the negative pressure is eliminated, the bottle cap at the bottom of the suction port 205 is accurately dropped into the collection device, minimizing the possibility of the bottle cap falling outside and improving the practicality of the device.

[0032] Working principle: The bottle cap is injection molded on a CNC injection molding machine. The electric push rod 203 pushes the movable plate 202 downwards, moving the suction port 205 above the bottle cap. The suction pump body 206 generates suction, creating a stable negative pressure space at the bottom of the suction port 205. The suction port 205 is made of elastic silicone to ensure a tight seal during suction. After the bottle cap is injection molded and cooled, the negative pressure suction overcomes the weight of the bottle cap and the adhesion force of the mold, smoothly detaching it from the mold cavity.

[0033] Secondly, by using the electric push rod 203, the bottle cap can be moved upward. Then, by using the drive motor 7, the lead screw 5 can be rotated, which can move the threaded block 8 on the outside of the lead screw 5. When the bottle cap is moved above the collecting device, the suction pump body 206 is then turned off. While the negative pressure is eliminated, the bottle cap at the bottom of the suction port 205 is accurately dropped into the collecting device, minimizing the possibility of the bottle cap falling outside and improving the practicality of the device.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
