As one of the three core components of new energy electric vehicles, the rotor thermosetting, as one of the core processes, its thermosetting quality directly affects the performance of the electric drive. The epoxy encapsulant material used in the special machine thermosetting equipment needs to be preheated before being put into the equipment. After preheating, the epoxy encapsulant material has a high temperature and a soft texture. In the prior art, the jaws for grasping the epoxy encapsulant material in new energy vehicle production are generally made of stainless steel and are in a V shape. Due to the high thermal conductivity of the metal jaws, the soft material cake is likely to slip during the process of being grasped from the thermosetting equipment and put into the material channel, and the heat conduction between the material cake and the jaws causes the temperature of the material cake to drop too fast, seriously affecting the injection molding quality and production progress.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] In the prior art, the jaws for grasping epoxy encapsulant are generally made of stainless steel and are in a V shape. Since the thermal conductivity of the metal jaws is relatively high, the softening cake is likely to slip during the process of being grasped from the thermal curing equipment and put into the material channel, and the temperature of the cake drops too fast due to heat conduction between the cake and the jaws, seriously affecting the injection molding quality and production progress.

[0021] In view of this, the present invention provides a gripper mechanism for a new energy electric drive rotor wire to grasp epoxy encapsulant. Through the cooperation among a base plate, a rotary cylinder, a first connecting plate, a gripper cylinder, a polytetrafluoroethylene gripper, an arc-shaped groove, epoxy encapsulant, a second connecting plate, and a laser sensor, by controlling the gripper cylinder, the epoxy encapsulant can be stably clamped in the arc-shaped groove of the polytetrafluoroethylene gripper. And by moving the gripper mechanism, after the epoxy encapsulant is moved to the feeding port of the special machine heat setting equipment, the epoxy encapsulant is rotated by the rotary cylinder, and the gripper cylinder is controlled to release the grasping and clamping of the epoxy encapsulant by the polytetrafluoroethylene gripper, so that the epoxy encapsulant enters the feeding port of the special machine heat setting equipment under the action of gravity, realizing the grasping and feeding operations of the epoxy encapsulant. Using polytetrafluoroethylene material as the gripper of the gripper mechanism has the characteristics of heat resistance, low friction coefficient, low thermal conductivity, etc., effectively reducing the heat loss of the preheated epoxy encapsulant and preventing the heated and softened epoxy encapsulant from adhering to the gripper. At the same time, the arc-shaped groove is used to grasp and clamp the epoxy encapsulant, avoiding the epoxy encapsulant from slipping during the movement process.

[0022] Through those skilled in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and appropriate controllers and encoders should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, the electrical connection should be completed with reference to the sequence of the working order among the electrical components in the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0023] As Figures 1-6 It can be seen that a gripper mechanism for a new energy electric drive rotor wire to grasp epoxy encapsulant includes a base plate 1. The base plate 1 is used to be fixed to the driving end of the robot or other driving components, and then move the gripper mechanism along a set route. A rotary cylinder 2 is installed on one side of the base plate 1. The output end of the rotary cylinder 2 is fixedly connected to a first connecting plate 3. A gripper cylinder 4 is installed on the outer wall of the first connecting plate 3. The output end of the gripper cylinder 4 is provided with a polytetrafluoroethylene gripper 5. Arc-shaped grooves 6 are provided on the sides of the two polytetrafluoroethylene grippers 5 close to each other. The inner wall of the arc-shaped groove 6 is cooperatively connected with epoxy encapsulant 7. A second connecting plate 8 is fixedly connected to one side of the outer wall of the gripper cylinder 4. A laser sensor 9 is installed on the side of the second connecting plate 8 away from the gripper cylinder 4. The laser sensor 9 is arranged corresponding to the epoxy encapsulant 7;

[0024] In the specific implementation process, it is particularly worth noting that the base plate 1 is used to be fixed to the robot drive end or other drive components, and then move the jaw mechanism along a set route. Through the cooperation among the base plate 1, the rotary cylinder 2, the first connecting plate 3 and the jaw cylinder 4, by controlling the rotary cylinder 2, the rotation adjustment of the first connecting plate 3 and the jaw cylinder 4 is realized, and then the precise angle adjustment of the jaw assembly connected to the end of the jaw cylinder 4 is realized. Through the cooperation among the jaw cylinder 4, the polytetrafluoroethylene jaw 5, the arc-shaped groove 6 and the epoxy potting compound 7, the jaws of the jaw mechanism are made of polytetrafluoroethylene material, which has the characteristics of heat resistance, low friction coefficient and low thermal conductivity coefficient, effectively reducing the heat loss of the epoxy potting compound 7 after preheating and preventing the heated and softened epoxy potting compound 7 from adhering to the jaws. The arc-shaped grooves 6 of the symmetric jaws form a material clamping space, with a large opening on the upper side and a small opening on the lower side, and the surface roughness of the arc-shaped groove 6 is less than 1.6, which is used to ensure that the epoxy potting compound 7 softened after heating will not fall off after being clamped. By controlling the jaw cylinder 4, the polytetrafluoroethylene jaw 5 is driven to move, realizing the clamping and grasping of the epoxy potting compound 7 in the arc-shaped groove 6, and releasing the clamping to carry out material feeding after moving to the designated position. Through the cooperation among the jaw cylinder 4, the polytetrafluoroethylene jaw 5, the arc-shaped groove 6, the epoxy potting compound 7, the second connecting plate 8 and the laser sensor 9, the distance between the laser sensor 9 and the epoxy potting compound 7 is measured in real time, facilitating the monitoring of the grasping and feeding conditions of the epoxy potting compound 7 by the control system, improving the feeding automation and feeding efficiency of the special machine heat curing equipment. Through the cooperation among the base plate 1, the rotary cylinder 2, the first connecting plate 3, the jaw cylinder 4, the polytetrafluoroethylene jaw 5, the arc-shaped groove 6, the epoxy potting compound 7, the second connecting plate 8 and the laser sensor 9, by controlling the jaw cylinder 4, the epoxy potting compound 7 can be stably clamped in the arc-shaped groove 6 of the polytetrafluoroethylene jaw 5, and by moving the jaw mechanism, after the epoxy potting compound 7 moves to the feeding port of the special machine heat curing equipment, the epoxy potting compound 7 is rotated by the rotary cylinder 2, and the jaw cylinder 4 is controlled to release the grasping and clamping of the epoxy potting compound 7 by the polytetrafluoroethylene jaw 5, so that the epoxy potting compound 7 enters the feeding port of the special machine heat curing equipment under the action of gravity, realizing the grasping and feeding operations of the epoxy potting compound 7. Using polytetrafluoroethylene material as the jaws of the jaw mechanism has the characteristics of heat resistance, low friction coefficient and low thermal conductivity coefficient, effectively reducing the heat loss of the epoxy potting compound 7 after preheating and preventing the heated and softened epoxy potting compound 7 from adhering to the jaws. At the same time, the arc-shaped groove is used to clamp and grasp the epoxy potting compound 7 to avoid the epoxy potting compound 7 from slipping during the movement. The specific models of the rotary cylinder 2, the jaw cylinder 4 and the laser sensor 9 are not limited, as long as they meet the use requirements;

[0025] Further, a connecting protrusion 10 is provided on one side of the polytetrafluoroethylene jaw 5 close to the jaw cylinder 4. Fixed grooves 11 are formed on the sides of the two connecting protrusions 10 close to each other. The output end of the jaw cylinder 4 is in fit connection with the fixed grooves 11. First fixing holes 12 are equidistantly formed inside the fixed grooves 11 where the connecting protrusions 10 are located. The connecting protrusions 10 are fixedly connected to the output end of the jaw cylinder 4 through the first fixing holes 12;

[0026] In the specific implementation process, it is particularly worth pointing out that through the cooperation among the jaw cylinder 4, the polytetrafluoroethylene jaw 5, the connecting protrusion 10, the fixed groove 11 and the first fixing hole 12, by inserting bolts into the first fixing holes 12, the driving rod of the jaw cylinder 4 is fixed in the fixed groove 11, improving the connection stability between the driving rod of the jaw cylinder 4 and the polytetrafluoroethylene jaw 5, thereby ensuring the accuracy and reliability of the entire jaw mechanism during operation, and enhancing the connection strength between components to achieve the compactness of the structure;

[0027] Further, a fixing plate 13 is provided at one end of the base plate 1 away from the rotating cylinder 2. Second fixing holes 14 are equidistantly formed on the outer wall of the fixing plate 13;

[0028] In the specific implementation process, it is particularly worth pointing out that through the cooperation among the base plate 1, the fixing plate 13 and the second fixing holes 14, by inserting bolts into the second fixing holes 14, the fixing plate 13 is installed and fixed to the robot driving end or other driving components, realizing the fixation of the jaw mechanism to the robot driving end or other driving components, and then precisely adjusting the position and firmly connecting the jaw mechanism to ensure the stability and reliability of the jaw mechanism during operation;

[0029] Further, reinforcing plates 15 are equidistantly arranged on one side of the fixing plate 13 close to the first connecting plate 3. The reinforcing plates 15 are used to improve the connection strength at the joint between the base plate 1 and the fixing plate 13, enhancing the overall stability and reliability of the jaw mechanism. The reinforcing plates 15 are used to improve the connection strength at the joint between the base plate 1 and the fixing plate 13, and the reinforcing plates 15 are respectively fixedly connected to the base plate 1 and the fixing plate 13;

[0030] In the specific implementation process, it is particularly worth pointing out that the reinforcing plates 15 are used to improve the connection strength at the joint between the base plate 1 and the fixing plate 13, enhancing the overall stability and reliability of the jaw mechanism;

[0031] Further, a support plate 16 is embedded on the sides of the polytetrafluoroethylene jaw 5 and the connecting protrusion 10 away from the arc-shaped groove 6;

[0033] Furthermore, bevels 17 are provided on the sides of the polytetrafluoroethylene jaws 5 and the support plate 16 away from the arc-shaped groove 6. The bevels 17 are used to reduce the volume and weight of the polytetrafluoroethylene jaws 5, making the actions of grasping and feeding the epoxy encapsulant 7 smoother.

[0034] In the specific implementation process, it is particularly worth noting that the bevels 17 are used to reduce the volume and weight of the polytetrafluoroethylene jaws 5, making the actions of grasping and feeding the epoxy encapsulant 7 smoother.

[0035] Working principle: The preheated epoxy encapsulant 7 is horizontally placed at the position to be grasped by the preheating device. When it is necessary to add the epoxy encapsulant 7 to the dedicated machine heat curing device, the driving end of the robot or other driving components drive the jaw mechanism to move above the epoxy encapsulant 7. At this time, the jaw cylinder 4 is in the open state, and the rotary cylinder 2 rotates the jaws to both sides above the epoxy encapsulant 7, and makes the jaw mechanism continue to move down to an appropriate grasping position. Control the jaw cylinder 4 to close, so that the polytetrafluoroethylene jaws 5 clamp and grasp the epoxy encapsulant 7 in the arc-shaped groove 6. Make the jaw mechanism move upward, and the laser sensor 9 senses the in-place situation of the epoxy encapsulant 7. After the control system senses that the epoxy encapsulant 7 is in place, control the rotary cylinder 2 to rotate 90 degrees, so that the epoxy encapsulant 7 is adjusted from a horizontal posture to a vertical posture. Move the jaw mechanism to make the epoxy encapsulant 7 move above the feeding port of the dedicated machine heat curing device. Control the jaw cylinder 4 to open, so that the polytetrafluoroethylene jaws 5 release the clamping of the epoxy encapsulant 7. The epoxy encapsulant 7 slides into the feeding port of the dedicated machine heat curing device under the action of gravity. Delay for 2 seconds, and the laser sensor 9 senses that the occupancy signal disappears, ensuring that the epoxy encapsulant 7 has completed the feeding. The control system automatically controls the jaw mechanism to reset and waits for the next grasping operation.
