Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Example 1 This embodiment provides an injection molding and assembly device for a relay housing, as shown in the attached diagram. Figures 2-7 As shown, it includes: Mold 11 is formed with a first component 101 and a second component 102, connected by a connecting part 103. The mold 11 has cavities designed according to the structural shapes of the first component 101 and the second component 102. The number of cavities can be adjusted according to actual needs. The connecting part 103 contains waste material generated during the injection molding process, i.e., the residue left after the colloid flows into the cavity through the runner.

[0027] Assembly module 12 includes a main board 13, a secondary board 14, and a rotating mechanism. The main board 13 and the secondary board 14 are rotatably connected. This rotatable connection can be a hinge connection or a pin connection, which can be adjusted according to actual needs by those skilled in the art. It should be noted that in the normal state, the top surfaces and bottom surfaces of the two are coplanar, thus forming a horizontal arrangement. When rotation occurs and is in place, the main board 13 and the secondary board 14 are arranged vertically. The secondary board 14 can be located below the main board 13, or the main board 13 can be located below the secondary board 14. In this embodiment, the secondary board 14 is located below the main board 13 as an example. After rotation, the secondary board 14 and the main board 13 are arranged vertically and parallel to each other. The rotating mechanism drives the main board 13 or the secondary board 14 to rotate. Both the main board 13 and the secondary board 14 are fixed with suction mechanisms. The suction mechanisms correspond to the positions of the cavities. For example, if the number of cavities is arranged in a 2*3 pattern, the suction mechanisms are also arranged in a 2*3 pattern, or other array methods can be used. The suction mechanism on the main board 13 picks up the first component 101, and the suction mechanism on the sub-board 14 picks up the second component 102. A clamping mechanism 15 is fixed between the main board 13 and the sub-board 14. The clamping mechanism 15 clamps the connecting part 103. It should be noted that in order to ensure that the main board 13 and the sub-board 14 rotate into place, there is a gap between them so that there will be no interference during rotation, and the clamping mechanism 15 will not interfere with the rotation during rotation.

[0028] In the first state, the mold 11 is injection molded. The moving mold and the fixed mold cooperate to form the corresponding cavity. By injecting colloid, the injection molding effect is finally achieved, which corresponds to the first part 101 and the second part 102. This processing mold 11 can be accurately manufactured by those skilled in the art who know the structure of the relay housing. Therefore, the detailed structure of the mold 11 is not shown in this embodiment.

[0029] In the second state, mold 11 opens, which means that the moving mold and the fixed mold move relative to each other. Assembly module 12 extends between the moving mold and the fixed mold. The suction mechanism picks up the corresponding first component 101 and second component 102. The clamping mechanism 15 clamps the connecting part 103. Assembly module 12 removes the first component 101 and the second component 102 from mold 11.

[0030] In the third state, the clamping mechanism 15 separates the connecting part 103 from the first component 101 and the second component 102. The clamping mechanism 15 operates, causing the connecting part 103 to separate and form waste. Here, the clamping mechanism 15 creates an impact effect, while the first component 101 and the second component 102 are fixed under the suction action of the suction mechanism. At this time, the connecting part 103 can be easily separated, and then the connector is collected by the waste collector.

[0031] In the fourth state, the rotating mechanism operates, and the main board 13 and the sub-board 14 rotate relative to each other, causing the first component 101 and the second component 102 to engage. For example, the sub-board 14 rotates 180° to a position below the main board 13, causing the first component 101 and the second component 102 to engage. Here, a snap-fit ​​structure is provided between the first component 101 and the second component 102. When the two are aligned and a certain pressure is applied, the engagement is completed. This is existing technology.

[0032] In the fifth state, the assembly module 12 places the assembled shell on the discharge platform 19. An operator is assigned to the discharge platform 19 to collect and place the shell.

[0033] Using this equipment, after injection molding is completed, the mold 11 opens, and the suction mechanism directly picks up the formed first part 101 and second part 102. Then, by removing waste material and rotating the mechanism, the parts are assembled in mid-air, completing the assembly of the relay housing. Finally, the housing is placed on the unloading platform 19. This structure eliminates the intermediate transfer step, and the mid-air assembly by the equipment eliminates the need for workbenches and manual assembly, greatly improving overall efficiency and meeting production needs.

[0034] Specifically, as shown in the attached document Figures 2-6 As shown, there are two sub-plates 14, which are respectively located on both sides of the main plate 13. Each sub-plate 14 has N second components 102 fixed to it, and the main plate 13 has 2N first components 101 fixed to it. In this embodiment, the cavities of the mold 11 are arranged in a 4*3 pattern, meaning the six cavities in the middle are for injection molding of the first components 101, and the three cavities on both sides are for injection molding of the second components 102. During the suction and clamping process, the suction mechanism on the main plate 13 picks up 2*3 first components 101, and the suction mechanism on the sub-plate 14 picks up 3 second components 102, thus forming a clamping effect. During rotation, each of the two sub-plates 14 corresponds to a set of first components 101, ultimately forming a combined effect of six shells. By cooperating with the two sub-plates 14 and the main plate 13, multiple relay shells can be processed simultaneously, improving processing efficiency. In this embodiment, the number and array arrangement can be adjusted according to actual needs, and can also be 4*4 or other arrangements. Alternatively, a long strip structure can be used to increase the length of the suction mechanism.

[0035] Specifically, as shown in the attached document Figures 2-6 As shown, the rotating mechanism drives the secondary plate 14 to rotate. The rotating mechanism includes a first driving source 16, and the first driving source 16 and the secondary plate 14 are connected by a belt drive. That is, when the first driving source 16 is working, it drives the secondary plate 14 to rotate through the belt drive. The rotation angle of the secondary plate 14 can be adjusted according to actual needs. For example, when the first component 101 and the second component 102 need to be engaged, the rotation angle of the secondary plate 14 is 180°. Alternatively, the first driving source 16 and the secondary plate 14 can be connected by a chain drive, which, like the belt drive, can achieve the rotation effect of the secondary plate 14. Alternatively, the first driving source 16 and the secondary plate 14 can be connected by a gear drive, which also achieves the rotation effect of the secondary plate 14. In this structural configuration, the main plate 13 is fixed, and the first component 101 and the second component 102 are joined by rotating the secondary plate 14. In addition, the secondary plate 14 can also be fixed, and the main plate 13 can rotate.

[0036] Specifically, as shown in the attached document Figures 2-7 As shown, the clamping mechanism 15 includes a fixed plate 151, a first drive assembly, and a clamping assembly. The fixed plate 151 is connected to the main board 13. Both the first drive assembly and the clamping assembly are fixed to the fixed plate 151, located near the connection gap between the main board 13 and the sub-board 14. The first drive assembly drives the clamping assembly to move along a third direction. The first drive assembly includes a second drive source 152, which can be a cylinder, a hydraulic cylinder, or a motor. The third direction is specifically the Z-axis direction. The clamping assembly includes two grippers 153, which move along a second direction to create a clamping effect. The grippers 153 move relative to each other, creating a clamping or releasing effect. Here, the second direction is the Y-axis direction. The second direction is perpendicular to the third direction, meaning the clamping assembly can clamp the connecting part 103 or move downwards along the Z-axis, causing the connecting part 103 to separate from the first component 101 and the second component 102. The clamping mechanism 15 makes clamping more convenient, and the first drive component can also break the connection between the connecting part 103 and the first component 101 and the second component 102.

[0037] Specifically, the clamping component is a finger cylinder, and the gripper 153 is part of the finger cylinder. The inclusion of a finger cylinder makes installation and control more convenient.

[0038] Specifically, after the third state ends, the rotating mechanism drives the sub-plate 14 to rotate, creating a shaking effect. This shaking effect is designed to prevent the connecting parts 103 from sticking together and affecting subsequent assembly. Here, the shaking specifically refers to the rapid, small-amplitude rotation of the sub-plate 14; for example, the sub-plate 14 rotates 5°, returns to its original position, rotates another 5°, and returns to its original position, thus creating the shaking effect.

[0039] Specifically, after the fourth state is completed, the rotating mechanism drives the sub-plate 14 to rotate, creating a striking effect. In the fourth state, the sub-plate 14 rotates 180°, causing the first component 101 and the second component 102 to assemble. After assembly, a second striking action ensures the accuracy of the assembly; that is, the sub-plate 14 rotates another 180°, creating a striking effect between the main board 13 and the sub-plate 14. This striking effect improves the assembly effect between the first component 101 and the second component 102, preventing improper assembly.

[0040] Specifically, after the assembly module 12 picks up the first component 101 and the second component 102 from the mold 11, its subsequent third state, fourth state, shaking effect, and slapping effect are all performed in the air, that is, above the mold 11 and the discharge table 19 in the Z-axis direction, which improves space utilization. This structural setting also enables the assembly of the first component 101 and the second component 102 through the assembly module 12 during the process from mold release to material discharge. At this time, there is no need for material turnover, saving process and labor costs, and greatly improving the overall processing efficiency.

[0041] Specifically, the suction mechanism is a combination of a suction nozzle and an air tube. When air is drawn into the air tube, creating a vacuum, the suction nozzle achieves a vacuum adsorption effect, drawing in the corresponding first component 101 or second component 102. Conversely, when the air tube is filled with air, the suction nozzle fails, resulting in a discharge effect. This is prior art. In this embodiment, the main board 13 and the sub-board 14 are provided with through holes 131 corresponding to the suction mechanism, which are used to fix the suction nozzle.

[0042] Specifically, as shown in the attached document Figure 2 As shown, it also includes a multi-axis motion module 17. The multi-axis motion module 17 drives the assembly module 12 to move along a first direction, a second direction, and a third direction. The multi-axis motion module 17 also drives the assembly module 12 to rotate. The multi-axis motion module 17 can drive the assembly module 12 to move along the X-axis, Y-axis, and Z-axis, and can also drive the assembly module 12 to rotate, achieving multi-directional collaboration. Here, a gantry frame can be used to achieve multi-directional movement. As for the multi-axis motion module 17 driving the assembly module 12 to rotate, a turntable structure can be used to create the rotation effect. Specifically, the multi-axis motion module 17 is connected to the mainboard 13, enabling the mainboard 13 to move in different directions. Alternatively, it may also include a multi-axis robot. The multi-axis robot drives the assembly module 12 to move along a first direction, a second direction, and a third direction, and can also drive the assembly module 12 to rotate. The multi-axis robot and the multi-axis motion module 17 operate on the same principle, both enabling the assembly module 12 to move in different directions. The difference lies in the higher controllability and precision of the multi-axis robot.

[0043] Specifically, the entire device is controlled by a PLC.

[0044] Specifically, the mold 11 is housed inside the protective box 18. During the injection molding process, the protective box 18 is in a closed state. After the injection molding is completed, the top surface of the protective box 18 is opened (at the same time, the mold 11 is opened), and the assembly module 12 can pass through the top surface of the protective box 18 and extend into the mold 11 to form a suction and clamping operation.

[0045] Specifically, its working principle is as follows: the mold 11 is injection molded in the protective box 18. The mold opening direction is along the first direction, that is, along the X-axis direction. The multi-axis moving module 17 drives the assembly module 12 to rotate 90°, that is, the main board 13 and the sub-board 14 change from the horizontal direction to the vertical direction. Then, the multi-axis moving module 17 passes through the top surface of the protective box 18 along the Z-axis direction and extends into the mold 11 (between the moving mold and the fixed mold) to form a suction and clamping operation (when the mold 11 opens along the Z-axis direction, the main board 13 and the sub-board 14 do not need to adjust their direction and move directly into the mold 11). After the initial suction is completed, the multi-axis moving module 17 moves the assembly module 12 along the Z-axis to outside the protective box 18 (at this time, the mold 11 performs injection molding again). The multi-axis moving module 17 then rotates and resets the assembly module 12, causing the main board 13 and the sub-board 14 to change from a vertical to a horizontal position and move towards the top of the discharge platform 19. During this movement, the third state, shaking effect, fourth state, and tapping effect are performed, ultimately forming the assembly of the first component 101 and the second component 102. The assembled shell is located on the two sub-boards 14 and then placed on the discharge platform 19 for collection. After the assembly module 12 is placed, it can move back to the top of the protective box 18, at which point the mold 11 completes the next round of injection molding, ensuring a consistent processing rhythm and eliminating waiting steps.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
