[0042] See also Figure 1-15 , the present invention provides a technical solution:

[0043] An assembly robot for parts assembly includes a base 1 and a manipulator body 11. The base 1 and the manipulator body 11 are common structures, and will not be described in detail herein. The assembly robot also includes:

[0044] A fixed seat 12, the fixed seat 12 is arranged at one end of the manipulator body 11 away from the base 1;

[0045] A material storage box 2, which is movably arranged on a fixed seat 12 and is used to store unused components. The components in this solution are high-frequency transformers;

[0046] The top and bottom of the material storage box 2 are both open structures. A guide seat 21 is provided at the bottom of the material storage box 2. A sealing plate 22 is slidably provided in the guide seat 21. A spring 23 is provided between the material storage box 2 and the sealing plate 22. The sealing plate 22 movably runs through the material storage box 2. The setting of the sealing plate 22 and the spring 23 can limit the components when placing the components in the material storage box 2. When the high-frequency transformer is placed, the pins are placed horizontally and all face the same direction to facilitate the positioning of the subsequent bending plate 42.

[0047] The blanking assembly unit 3 is arranged on the fixing seat 12, and is used to control the components in the storage box 2 to fall into the fixing seat 12, and place the components on the circuit board with the cooperation of the manipulator body 11;

[0048] The blanking assembly unit 3 includes a mounting frame 31 arranged on a fixed seat 12, a control member 4 used in conjunction with a material storage box 2 is arranged on the mounting frame 31, and is used to control the components in the material storage box 2 to fall into the fixed seat 12, a mounting frame 2 32 is arranged in the fixed seat 12, an assembly component 5 is arranged on the mounting frame 2 32, and is used to receive the fallen components and rotate the pin position to the side opposite to the circuit board, so that the components can be fitted with the circuit board through the manipulator body 11, a feed port connected to the material storage box 2 is arranged on the top of the fixed seat 12, and a discharge port is arranged on the bottom, a controller 33 connected to the manipulator body 11 is arranged on the fixed seat 12, the manipulator body 11 is self-contained with program control, and is connected to the controller 33 signal, so that the controller 33 can work through the program control;

[0049] The control member 4 includes an electric push rod 41 arranged on a mounting frame 31, a bent plate 42 is arranged at the end of the electric push rod 41, a rectangular groove 43 which can be connected with the material storage box 2 and the discharge port is provided on the bent plate 42, and a shift slot for shift adjustment of the bent plate 42 is provided on the side of the material storage box 2 away from the sealing plate 22, the top of the bent plate 42 can be inserted between the penultimate component and the penultimate component, and is used to position the penultimate component, and the bottom of the bent plate 42 can contact the sealing plate 22, because of the skeleton structure of the high-frequency transformer, this enables the bent plate 42 to pre-limit the penultimate high-frequency transformer, and automatically fall when resetting, because the pin-free end of the high-frequency transformer is always close to one side of the bent plate 42, therefore, after falling from the rectangular groove 43, its skeleton is always located at the bottom, that is, it fits the receiving plate 64;

[0050] The assembly component 5 includes a rotating frame 51 movably arranged on the second mounting frame 32, a rotating member 6 is arranged between the second mounting frame 32 and the rotating frame 51, and is used to drive the rotating frame 51 to rotate, thereby rotating the pin position of the components on it to the side opposite to the circuit board, and a clamping member 7 is arranged on the rotating frame 51, and is used to clamp and position the components;

[0051] The rotating member 6 includes a rotating shaft 61 rotatably arranged on the second mounting frame 32, a first motor 62 connected to the rotating shaft 61 is arranged on the second mounting frame 32, the rotating frame 51 is arranged on the rotating shaft 61, a second spring 63 is arranged on the second mounting frame 32, and a receiving plate 64 for receiving components is arranged on the second spring 63;

[0052] The clamping member 7 includes a bidirectional screw rod 71 rotatably arranged on the rotating frame 51, and positioning plates 72 are respectively threadedly connected to the two sides of the bidirectional screw rod 71, and the bottom of the positioning plates 72 are slidably arranged on the rotating frame 51, and a second motor 73 connected to the bidirectional screw rod 71 is arranged on the rotating frame 51;

[0053] A support frame 13, the support frame 13 is arranged on the base 1;

[0054] The box replacement unit 8 is arranged on the support frame 13 and is used to automatically complete the replacement of the storage box 2 after the components in the storage box 2 are used up;

[0055] The box replacement unit 8 includes a box loading and unloading member 9 arranged on the support frame 13, which is used to remove and install the storage box 2 from the fixed seat 12, a positioning seat 1 81 is arranged on the mounting frame 1 31, and a positioning seat 2 82 used in conjunction with the positioning seat 1 81 is arranged on the storage box 2, and a functional locking member 10 used in conjunction with the box loading and unloading member 9 is arranged between the positioning seat 1 81 and the positioning seat 2 82, which is used to cancel the locking and positioning of the storage box 2 when the storage box 2 is removed, and can lock and position the storage box 2 when the storage box 2 is installed;

[0056] The box loading and unloading member 9 includes two U-shaped seats 91 respectively arranged on both sides of the support frame 13, and each of the U-shaped seats 91 is provided with a fixing groove 92 that can be simultaneously inserted into the positioning seat 1 81 and the positioning seat 2 82;

[0057] The functional locking member 10 includes an installation cavity 101 arranged in the first positioning seat 81, a piston rod 102 is movably arranged in the installation cavity 101, a connecting rod 103 is arranged at the end of the piston rod 102, a round tube 104 is arranged in the first positioning seat 81, a shifting card rod 105 connected to the connecting rod 103 is movably arranged in the round tube 104, a spring 3 106 is arranged between the shifting card rod 105 and the round tube 104, and a card slot 107 engaged with the shifting card rod 105 is provided on the second positioning seat 82. When the shifting card rod 105 is disengaged from the card slot 107, the first positioning seat 81 and the second positioning seat 82 are separated, so that the storage box 2 can be separated from the fixed seat 12, and the positioning seat An extrusion airbag 108 is provided on 81, and the extrusion airbag 108 and the installation cavity 101 are connected by a hose. The extrusion airbag 108 can contact the top of the U-shaped seat 91. A functional groove 109 is opened on the top of any U-shaped seat 91. The U-shaped seat 91 with the functional groove 109 has the function of assembling the storage box 2, and the other U-shaped seat 91 without the functional groove 109 has the function of removing the storage box 2. When in use, it is only necessary to control the adjustment of the manipulator body 11 so that the storage box 2 on the fixed seat 12 first passes through the U-shaped seat 91 without the functional groove 109, removes the storage box 2, and then passes through the U-shaped seat 91 with the functional groove 109 to reinstall a new storage box 2.

[0058] When in use, first, the storage box 2 is used as a container for storing components to be assembled, and is movably arranged on the fixed seat 12. The storage box 2 adopts a structural design with both the top and the bottom being open, and a guide seat 21 and a sealing plate 22 are provided at the bottom. The sliding of the sealing plate 22 is controlled by a spring 23, thereby controlling the falling out of the components.

[0059] Next, the blanking assembly unit 3 is located on the fixed seat 12, and is composed of a control member 4 on the mounting frame 31 and an assembly component 5 in the fixed seat 12. The control member 4 drives the bending plate 42 to move through the electric push rod 41. The rectangular groove 43 provided on the bending plate 42 is connected with the storage box 2 and the discharge port. The bending plate 42 can be inserted between the components to locate the second-to-last component, and the sealing plate 22 is pushed to move through the bottom of the bending plate 42 to release the first-to-last component to the assembly component 5;

[0060] The assembly assembly 5 includes a rotating frame 51, a rotating member 6 and a clamping member 7. The component first falls on the receiving plate 64 in the rotating member 6. At this time, the skeleton of the component is located at the bottom and the pins are located at the top. The rotation of the second motor 73 in the clamping member 7 drives the bidirectional screw rod 71 to rotate, and then drives the positioning plates 72 on both sides to shift inward to clamp the skeleton position of the component. After clamping and positioning, the first motor 62 starts to work under the action of the controller 33. The first motor 62 drives the rotating shaft 61 to rotate, and then drives the rotating frame 51 located thereon to rotate 180° to adjust the pin position of the component. When rotating, the receiving plate 64 will change its own state as the component rotates, that is, from a horizontal state to an inclined state. However, after the component is detached, it is reset under the action of the second spring 63. Because when the rotating frame 51 is reset, the two positioning plates 72 are in a state of being located on both sides of the bidirectional screw rod 71, and no interference will occur.

[0061] During the assembly process, the robot body 11 places the components accurately on the assembly assembly 5 in the fixed seat 12 through the blanking assembly unit 3 according to the instructions, and adjusts its pin position. Then, the robot body 11 places the adjusted components accurately on the circuit board and cooperates with the welding machine to complete the assembly process.

[0062] When the components in the storage box 2 are used up, the box replacement unit 8 starts to work. The box replacement unit 8 includes a box loading and unloading part 9 and a functional locking part 10 between the positioning seat 1 81 and the positioning seat 2 82 arranged on the support frame 13. The box loading and unloading part 9 cooperates with the extrusion airbag 108 through the U-shaped seat 91 and the fixing groove 92 to realize the positioning and loading and unloading of the storage box 2. The functional locking part 10 controls the state of the shifting card rod 105 through the installation cavity 101, the piston rod 102, the connecting rod 103, the shifting card rod 105 and the spring three 106 and other components to realize the locking and unlocking of the storage box 2;

[0063] When it is necessary to replace the storage box 2, it is only necessary to control the adjustment of the manipulator body 11 so that the storage box 2 on the fixed seat 12 first passes through the U-shaped seat 91 without the functional groove 109. At this time, the extrusion airbag 108 on the positioning seat 1 81 contacts the top of the U-shaped seat 91, and the internal gas is squeezed. This part of the gas will push the piston rod 102 to shift, and at the same time drive the shifting card rod 105 to disengage from the card groove 107, canceling the locking positioning of the positioning seat 2. When the bottom of the U-shaped seat 91 is touched, the storage box 2 is removed. Since the positioning seat 1 81 and the positioning seat 2 82 can be inserted into the fixed groove 92 in the U-shaped seat 91 after being combined, when the storage box 2 and the positioning seat 2 82 are removed, the positioning seat 1 81 can still be detached from the fixed groove 92, and after detaching from the fixed groove 92, under the action of the spring 3 106, the shifting rod 105 and the piston rod 102 are driven to reset, and then the gas in the installation cavity 101 is pushed back into the extrusion airbag 108.

[0064] The adjustment of the manipulator body 11 is controlled again so that the storage box 2 on the fixed seat 12 passes through the U-shaped seat 91 with the functional groove 109. Due to the setting of the functional groove 109, the extrusion airbag 108 will not be squeezed at this time. When the positioning seat 1 81 and the positioning seat 2 82 are in contact, the shifting rod 105 is squeezed until it is engaged in the groove 107. By adjusting the manipulator body 11, it can leave the U-shaped seat 91. At this time, the reinstallation of a new storage box 2 is completed.

[0065] Example 2

[0067] Different from Example 1, a material guide pipe 14 is provided in the fixed seat 12, and the material guide pipe 14 is connected to the discharge port at the bottom of the fixed seat 12 and aligned with the receiving plate 64 at the bottom, so as to ensure that the high-frequency transformer falls on the receiving plate 64, so as to facilitate subsequent clamping, positioning and assembly work.
