Description

Technical Field

[0001] The invention relates to the technical field of robot grippers, in particular to a scissor-type injection molding robot gripper mechanism. Background Art

[0002] The FPC connector is usually composed of a plastic shell body, terminals and welding pieces. During the injection molding of the FPC plastic shell head, in order to facilitate the removal of the injection-molded FPC plastic shell head from the mold after mold opening, a corresponding injection molding robot is usually used. The clamping claws on the injection molding robot are used to clamp the molded FPC plastic shell head, thereby improving the processing efficiency of the FPC plastic shell.

[0003] For example, an injection molding anti-damage mold removal robot with publication number CN218315057U includes a clamping claw connecting frame and a cylinder, etc., the clamping claw connecting frame is equipped with a cylinder, and also includes a lifting rod, a loading plate and an adjusting connecting rod, etc. The lifting rod is connected to the telescopic rod of the cylinder, a loading plate is fixedly connected to one side of the loading plate, and an adjusting connecting rod is fixedly connected to the bottom of the lifting rod.

[0004] The above-mentioned prior art has the following technical problems: the existing manipulator is not convenient for playing a clamping and buffering role when taking out the material head in the mold, which leads to that when the manipulator clamps the material head with too much force, it is easy to cause the clamped material head to be deformed. At the same time, because the temperature of the material head is relatively high after the injection molding is completed, it is not convenient to play an auxiliary cooling role when clamping the material head, which leads to the need for a long time of cooling after the subsequent material head is taken out, reducing the work efficiency of the overall injection molding process.

[0005] Therefore, we proposed a scissor-type injection molding robot gripper mechanism to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a scissors-type injection molding robot clamping mechanism to solve the problem raised by the above background technology that the existing robots on the market are not convenient to play a clamping and buffering role when taking out the material head in the mold, which leads to that when the robot clamps the material head with too much force, it is easy to cause the clamped material head to deform. At the same time, because the temperature of the material head is relatively high after the injection molding is completed, it is not convenient to play an auxiliary cooling role for the clamped material head when clamping the material head, which leads to the need for a long time to cool down after the subsequent material head is taken out, thereby reducing the work efficiency of the overall injection molding process.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a scissor-type injection molding robot gripper mechanism, comprising a support seat, a robot connecting block interconnected with the robot is fixedly connected to the right end of the support seat, and a cylinder providing a driving force is fixedly connected to the upper right end of the support seat, a guide shaft is provided at the telescopic end of the cylinder, and a push block is fixedly installed at one end of the guide shaft away from the cylinder, a limit cover is provided on the outer side of the push block, and a driving shaft is fixedly connected to the left end of the push block, the driving shaft is inserted into a guide groove providing a sliding track on the first clamping jaw and the second clamping jaw, and a movable shaft is installed through the middle of the first clamping jaw and the second clamping jaw;

[0017] By adopting the above technical solution, the adjusting block can firstly contact with the clamped material head through the setting, and then the adjusting block is subjected to force to make the clamping column move on the clamping claw.

[0018] Preferably, the air squeezing part includes a piston rod, a accommodating chamber and a built-in spring, and the piston rod is installed inside the guide shaft, one end of the piston rod is fixed to the telescopic end of the cylinder, and the other end of the piston rod extends into the interior of the accommodating chamber, and the accommodating chamber is opened inside the guide shaft. The piston rod is connected to the interior of the accommodating chamber through the built-in spring, and the end of the piston rod extending into the interior of the accommodating chamber is circumferentially wrapped with a sealing component, and the sealing component is configured as a rubber sealing ring.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the scissor-type injection molding manipulator clamping mechanism can conveniently utilize the deformation of the elastic element to play a clamping buffering role when clamping the injection molding material head, thereby avoiding deformation of the clamped material head due to excessive clamping force, and at the same time, when clamping the material head, it is convenient to perform auxiliary blowing cooling on it, thereby reducing the cooling time required for the subsequent material head;

[0027] 1. A first clamp and a second clamp are provided. After the cylinder pushes the guide shaft to move, the push block and the drive shaft can be moved. The first clamp and the second clamp can be rotated around the movable shaft by the sliding of the drive shaft in the guide grooves of the first clamp and the second clamp. Then, the first clamp and the second clamp form a scissor-type clamp mechanism to clamp and transfer the material head.

[0028] 2. An adjustment block is provided. When the first clamp and the second clamp clamp the material head, the adjustment block first contacts the material head.

After the clamping column moves, the elastic deformation of the auxiliary spring can play a clamping buffer role, thereby avoiding damage to the material head due to excessive clamping force;

[0029] 3. A blocking column is provided. In the initial state, the blocking column is in the boss on the inner side of the drainage tube opening, so that the blocking column can be used to block and shield the opening of the drainage tube to prevent foreign matter from entering the drainage tube and blocking it when the material head does not need to be clamped. At the same time, the adjusting block can move to the outside of the clamping claw after being subjected to force. At this time, the drainage tubes at the upper and lower ends of the adjusting block move on the blocking column and the drainage rod. After the blocking column moves out of the boss on the inner side of the drainage tube opening, the drainage rod moves into the boss, thereby forming an air outlet gap at the opening of the drainage tube, thereby allowing normal ventilation;

[0030] 4. A piston rod is provided. When the piston rod moves inside the accommodating chamber, the airflow inside the accommodating chamber can be squeezed out to the inside of the regulating block through the air pipe. At this time, the airflow in the regulating block is blown out to the surrounding of the material head through the opening gaps of the drainage pipes at the upper and lower ends. The extruded airflow can accelerate the air flow rate around the material head, thereby playing an auxiliary cooling role on the material head. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0044] Example 1: Please refer to Figure 1-Figure 9 When the existing manipulator takes out the material head in the mold, it is not convenient to play the role of clamping and buffering, so when the manipulator clamps the material head too hard, it is easy to cause the clamped material head to deform. In order to solve this technical problem, this embodiment discloses the following technical content;

[0045] A scissors-type injection molding robot gripper mechanism, comprising a support seat 1, a robot connecting block 2 connected to the robot is fixedly connected at the right end of the support seat 1, and a cylinder 3 providing a driving force is fixedly connected above the right end of the support seat 1, a guide shaft 4 is provided at the telescopic end of the cylinder 3, and a push block 5 is fixedly installed at the end of the guide shaft 4 away from the cylinder 3, a limiting cover 6 is provided on the outer side of the push block 5, and a driving shaft 7 is fixedly connected to the left end of the push block 5, the driving shaft 7 is inserted into a guide groove 10 providing a sliding track on a first jaw 8 and a second jaw 9, and a movable shaft 11 is installed through the middle of the first jaw 8 and the second jaw 9; a buffer component 12 providing an elastic force is provided in the clamping area of ​​the first jaw 8 and the second jaw 9 for the material head, the outer wall of the driving shaft 7 and the inner wall of the guide groove 10 on the first jaw 8 and the second jaw 9 fit each other, and the guide grooves 10 on the first jaw 8 and the second jaw 9 are arranged in reverse. The first clamping jaw 8 and the second clamping jaw 9 are symmetrically arranged about the transverse center axis of the support seat 1, and the first clamping jaw 8 and the second clamping jaw 9 are both installed with a movable shaft 11, and the first clamping jaw 8 and the second clamping jaw 9 can rotate around the movable shaft 11 to form a scissor-type clamping jaw mechanism. The buffer component 12 includes an adjustment block 121, a clamping column 122 and an auxiliary spring 123, and the clamping column 122 is fixedly connected to the middle part of the outer side of the adjustment block 121, and the clamping column 122 is connected to the inside of the clamping jaw through the auxiliary spring 123. The cross section of the adjustment block 121 is set to an arc structure, and the clamping column 122 on the adjustment block 121 and the clamping jaw form a sliding connection structure.

[0046] When it is necessary to clamp the material head, the manipulator connecting block 2 is connected to the external manipulator. After the injection mold is opened, the support seat 1 is controlled by the manipulator to extend between the upper and lower molds, and then the cylinder 3 is turned on. After the cylinder 3 is turned on, the guide shaft 4 is first pushed to move. After the guide shaft 4 drives the push block 5 to move on the limit cover 6, the push block 5 can be used to make the drive shaft 7 move synchronously. At this time, the moved drive shaft 7 slides in the guide groove 10 on the first clamp 8 and the second clamp 9. Because the guide grooves 10 on the first clamp 8 and the second clamp 9 are set in the opposite direction, the drive shaft 7 slides in the guide grooves 10 on the first clamp 8 and the second clamp 9. After moving in the middle, the first clamping jaw 8 and the second clamping jaw 9 can rotate around the movable shaft 11, so that the first clamping jaw 8 and the second clamping jaw 9 form a scissor-type clamping jaw mechanism to clamp and fix the material head. When the first clamping jaw 8 and the second clamping jaw 9 clamp the material head, the adjusting block 121 on the inner side of the end of the first clamping jaw 8 and the second clamping jaw 9 first contacts with the material head. After the adjusting block 121 is subjected to force, the clamping column 122 can be moved on the clamping jaw, and the elastic deformation of the auxiliary spring 123 after the clamping column 122 moves can play a clamping and buffering role on the material head, thereby avoiding damage to the material head due to excessive clamping force of the first clamping jaw 8 and the second clamping jaw 9 on the material head.

[0047] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. Since the temperature of the stub is relatively high after injection molding, it is not convenient to assist in cooling the stub when clamping it, which results in a longer cooling time after the stub is taken out, reducing the work efficiency of the overall injection molding process. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 2-Figure 11 As shown;

[0048] The extrusion part includes a piston rod 13, a receiving chamber 131 and a built-in spring 132, and the piston rod 13 is installed inside the guide shaft 4, one end of the piston rod 13 is fixed to the telescopic end of the cylinder 3, and the other end of the piston rod 13 extends into the receiving chamber 131, and the receiving chamber 131 is opened inside the guide shaft 4. The piston rod 13 is connected to the inside of the receiving chamber 131 through the built-in spring 132, and the end of the piston rod 13 extending into the receiving chamber 131 is circumferentially wrapped with a sealing component, and the sealing component is set as a rubber sealing ring. The piston rod 13 forms a seamless sliding connection structure with the receiving chamber 131 through the sealing component fixedly connected at the end, and the airflow inside the receiving chamber 131 can enter the inside of the regulating block 121 through the air pipe 14, and the inside of the regulating block 121 is set as a hollow structure. An airflow cooling component is installed between the guide shaft 4 and the telescopic end of the cylinder 3, and the airflow cooling component consists of an air squeezing part and an air outlet part. The air squeezing part is located inside the guide shaft 4 and is fixedly connected to the telescopic end of the cylinder 3, and the air outlet part is located at the upper and lower ends of the buffer component 12, and is used to blow air around the material head to accelerate the air flow rate after clamping the material head, so as to assist in cooling the material head. The air outlet part is interconnected with the interior of the buffer component 12, and the air outlet part is interconnected with the buffer component 12 through an air pipe 14. The air outlet portion includes a drainage tube 15, a boss 151, a blocking column 152, a drain rod 153 and a fixed column 154, and the drainage tube 15 is fixedly installed at the upper and lower ends of the adjustment block 121, the inner side of the opening of the drainage tube 15 away from the adjustment block 121 is fixedly connected with the boss 151, and the blocking column 152 is inserted into the opening of the drainage tube 15, the outer end of the blocking column 152 is fixedly connected with the drain rod 153, and the drain rod 153 and one end of the fixed column 154 are fixed to each other, and the other end of the fixed column 154 is fixed to the clamp. The longitudinal section of the boss 151 is annular, and the inner wall of the boss 151 and the outer wall of the blocking column 152 fit each other, and the diameter of the blocking column 152 is greater than the diameter of the drain rod 153.

[0049] When the adjusting block 121 is forced to move toward the outside of the clamping jaws, the movement of the adjusting block 121 can make the drainage tube 15 at the upper and lower ends move synchronously. After the drainage tube 15 moves, the boss 151 inside the opening and the blocking column 152 are misaligned with each other, and the discharge rod 153 on the blocking column 152 enters the boss 151 on the inner side of the opening of the drainage tube 15, thereby forming an air outlet gap at the opening of the drainage tube 15. When the cylinder 3 pushes the guide shaft 4 to move to the limit distance, the cylinder 3 continues to extend, and the piston rod 13 can be pushed to move in the accommodating chamber 131 inside the guide shaft 4. After the piston rod 13 moves, the accommodating chamber 131 can be filled with air. The airflow inside 31 is transported to the inside of the regulating block 121 through the air delivery pipe 14 made of rubber hose material. At this time, after the airflow enters the inside of the regulating block 121, the airflow inside the regulating block 121 can be blown toward the material head through the opening gap of the drainage tube 15 connected thereto. By blowing the airflow around the material head, the air flow rate around the material head can be accelerated, which plays an auxiliary cooling role for the material head. In the initial state, the blocking column 152 is located in the internal boss 151 of the opening of the drainage tube 15, thereby blocking the opening of the drainage tube 15 to avoid impurities entering the inside of the drainage tube 15 and causing blockage when the material head does not need to be clamped.
