[0015] Furthermore, in the thickness direction of the support assembly, the pressure-applying member protrudes outward toward the support assembly and is able to press against the end face of the support assembly in the length direction.

[0016] Furthermore, the support assembly includes an end support platform and a middle support platform;

[0017] Along the length of the support assembly, the end support platform and the middle support platform are arranged sequentially, and the end support platform and the middle support platform can respectively press against the corresponding pressure member.

[0018] Furthermore, the top of the end support has a first groove for receiving the insert.

[0019] Furthermore, the positioning pin is disposed on the end support platform.

[0020] Furthermore, a buffer is installed between every two adjacent linear drive members.

[0034] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please refer to Figures 1-4 An auxiliary assembly fixture for connecting an injection-molded product 10 to an insert 20 includes a support assembly 1, a pressure applying mechanism 2, a pushing mechanism 3, and a fixture base plate 4. The support assembly 1, the pressure applying mechanism 2, and the pushing mechanism 3 are all mounted on the fixture base plate 4. The top surface of the support assembly 1 has a positioning pin 11 for positioning the injection-molded product 10. In the thickness direction of the support assembly 1, the pressure applying mechanism 2 and the pushing mechanism 3 are respectively disposed on both sides of the support assembly 1. The movable end of the pressure applying mechanism 2 is disposed opposite to the top surface of the support assembly 1, and the movable end of the pressure applying mechanism 2 can move relative to the support assembly 1. The movable end of the pushing mechanism 3 is used to contact the insert 20 and can translate relative to the support assembly 1.

[0036] Understandably, the injection molded product 10 is pre-positioned by the support component 1 and the positioning pin 11 on the support component 1, and then the pressure mechanism 2 is used to fix the position of the injection molded product 10 on the support component 1, thereby achieving the positioning of the injection molded product 10. In conjunction with the flat pushing mechanism 3, the insert 20 pre-assembled on the injection molded product 10 is pushed to connect tightly with the injection molded product 10, fully simulating the manual action of transferring the insert 20, realizing fully automated operation, improving the assembly accuracy and efficiency of the insert 20, and improving the product qualification rate.

[0037] In some embodiments, the pressure applying mechanism 2 includes at least two rotary pressing drive members 21; all the rotary pressing drive members 21 are arranged sequentially along the length direction of the support assembly 1, and the movable end of the rotary pressing drive member 21 can be arranged opposite to the top surface of the support assembly 1. Preferably, three rotary pressing drive members 21 are provided, and the rotary pressing drive members 21 are rotary pressing cylinders. The rotary pressing drive members 21 are used to cooperate with the support assembly 1 at multiple points to jointly limit the injection molded product 10, ensuring the positioning accuracy of the injection molded product 10 and improving the stability of the injection molded product 10.

[0038] In some embodiments, the pushing mechanism 3 includes at least two linear drive members 31; all linear drive members 31 are arranged sequentially along the length direction of the support assembly 1, and the movable end of the linear drive member 31 is equipped with a pressure member 32. Optionally, the linear drive member 31 is a linear cylinder, a linear push rod, or a linear servo motor; preferably, three linear drive members 31 are provided. The linear drive members 31 can push the insert 20 pre-assembled on the injection molded product 10 to move, thereby tightly connecting with the injection molded product 10, realizing the automatic assembly of the insert 20 and the injection molded product 10, ensuring the accuracy of the assembly angle of the insert 20 and making the thrust during the assembly process controllable, reducing the probability of deformation of the insert 20, and improving product quality. It is worth noting that before the linear drive member 31 extends, the distance between the pressure member 32 and the corresponding support platform surface should be greater than or equal to the distance between the end of the insert 20 closest to the pressure member 32 and the pressure member 32, to ensure that the pressure member 32 can press against the end of the insert 20 and thus push the insert 20 to tightly connect with the injection molded product 10.

[0039] In some embodiments, in the thickness direction of the support component 1, the pressure member 32 protrudes outward toward the support component 1 and can abut against the end face of the support component 1 in the length direction. The pressure member 32 is provided so that the driving force of the linear drive member 31 can be transmitted to the insert 20, ensuring the reliability of the operation of the linear drive member 31.

[0040] In some embodiments, the support assembly 1 includes an end support platform 12 and a middle support platform 13. The end support platform 12 and the middle support platform 13 are sequentially arranged along the length of the support assembly 1, and each end support platform 12 and the middle support platform 13 can abut against a corresponding pressure member 32. Preferably, two end support platforms 12 are provided, and the two end support platforms 12 are located on opposite sides of the length of the middle support platform 13. The end support platforms 12 and the middle support platform 13 provide support for different areas of the injection-molded product 10, thereby enabling the linear drive member 31 to apply pressure to the corresponding insert 20 in different areas of the injection-molded product 10 to complete the assembly. The end support platforms 12 and the middle support platform 13 can be integrated or separate.

[0041] In some embodiments, the top of the end support platform 12 has a first groove 121 for receiving the insert 20, and the top of the middle support platform 13 has a second groove 131 for receiving the insert 20. The first groove 121 and the second groove 131 are provided to adapt to the protruding portion (i.e., the installation area of ​​the insert 20) on the surface of the injection molded product 10, thereby improving the stability of the injection molded product 10 and facilitating the installation of the insert 20. Accordingly, a greater number of grooves can be provided on the end support platform 12 and the middle support platform 13 according to the actual structure of the injection molded product 10.

[0042] In some embodiments, the positioning pin 11 is disposed on the end support platform 12. Preferably, each of the two end support platforms 12 is provided with a positioning pin 11. The positioning pin 11 is used to match the positioning hole on the injection molded product 10 to improve the positioning accuracy and stability of the injection molded product 10.

[0043] In some embodiments, a buffer 33 is provided between every two adjacent linear drive members 31; in the length direction of the support assembly 1, the surface of each buffer 33 is flush with the end faces of the corresponding end support platform 12 and the middle support platform 13, so that the pressure member 32 presses against the buffer 33 and the corresponding support platform simultaneously after pushing the insert 20 to the designated position, ensuring the force balance of the pressure member 32 and avoiding the pressure member 32 being crushed due to the linear drive member 31 exceeding the range of motion of the pressure member 32.

[0044] In some embodiments, in the height direction of the support component 1, the top of the buffer 33 is recessed relative to the top of the movable end of the linear drive 31, providing clearance for the installation of the injection molded product 10 and the insert 20.

[0045] In some embodiments, the pushing mechanism 3 further includes a limiting member 34; the limiting member 34 is disposed opposite to the end of the support assembly 1 and the movable end of the linear drive member 31, so that the linear drive member 31 disposed adjacent to the limiting member 34 abuts against the limiting member 34, and the linear drive member 31 is movable relative to the limiting member 34. The limiting member 34 is provided to limit the linear drive member 31 and the pressure member 32 located at the end. Similar to the buffer member 33, the limiting member 34 can prevent the pressure member 32 from being crushed by the linear drive member 31.

[0046] In some embodiments, a manual valve 5 is also installed on the tooling base plate 4. The manual valve 5 is connected to the rotary pressing drive 21 and the linear drive 31 respectively. In addition, the rotary pressing drive 21 and the linear drive 31 are respectively equipped with regulating valves. The starting sequence of the rotary pressing drive 21 and the linear drive 31 is controlled by the regulating valves. The purpose is to ensure that when the manual valve 5 is opened, the rotary pressing drive 21 starts before the linear drive 31, so that after the rotary pressing drive 21 presses down on the injection molded product 10, the linear drive 31 pushes the insert 20 to complete the assembly, thus ensuring the reliability of the operation.
