The wiring terminals feature a screw-based anti-loosening design, facilitating wiring during installation and effectively improving construction efficiency. Figure 1 As shown, the detector base 100 has two mounting slots 110 arranged at a certain angle. Each mounting slot 110 is provided with a terminal assembly 120. The terminal assembly 120 is mainly composed of a nut 121, a spring plate 122 and a screw 123. The screw 123 is generally a square washer screw. Usually, during assembly, the nut 121 is first pressed into the nut groove of the mounting slot 110, then the spring plate 122 is placed into the corresponding mounting slot 110, and finally the screw 123 is screwed onto the nut 121 through the mounting hole of the spring plate 122.

[0003] With the rapid development of automation technology, replacing manual assembly work with automated assembly machines has become an inevitable trend. Currently, the assembly of the aforementioned detector base mostly uses a multi-station rotary table, which includes a base loading station, a nut pressing station, a spring plate installation station, a screw tightening station, and a unloading station. This type of assembly machine can complete automated assembly work in an orderly manner, but it requires a high-precision multi-station rotary table to switch stations, has high requirements for the coordination accuracy of each mechanism, and occupies a large overall space.

[0050] like Figure 8 and Figure 9As shown, in this embodiment, the base loading mechanism 7 further includes a base sliding positioning seat 7-4 located before the base rotating positioning seat 7-2, and a stacking mechanism located after the base rotating positioning seat 7-2. The base moving mechanism 8 is used to move the detector base 100 on the base sliding positioning seat 7-4 to the base rotating positioning seat 7-2, and simultaneously move the assembled detector base 100 on the base rotating positioning seat 7-2 to the stacking mechanism. The base moving mechanism 8 can stably transfer the detector base between the base sliding positioning seat 7-4, the base rotating positioning seat 7-2, and the stacking mechanism, allowing for direct stacking after base assembly, facilitating subsequent product packaging, etc. The base sliding positioning seat 7-4 has positioning structures such as positioning posts for positioning the detector base 100. The base sliding positioning seat 7-4 is slidably mounted on one side of the base assembly table 7-1 via guide rails, enabling the transfer of the detector base 100 from the previous process to the loading station of the base assembly table 7-1. This ensures that the distance from the loading station to the base rotating positioning seat 7-2 is equal to the distance from the base rotating positioning seat 7-2 to the stacking mechanism, facilitating synchronous transfer using the base moving mechanism 8. Figure 10 As shown, the aforementioned base moving mechanism 8 includes a lifting platform 8-1, a lifting guide column 8-2, a lifting drive cylinder 8-3, a translation cylinder 8-4, a long guide rail 8-5, a gripper mounting base 8-6, and a pneumatic gripper 8-7. The lifting platform 8-1 is mounted on the frame 1 via the lifting guide column 8-2. The drive end of the lifting drive cylinder 8-3 is connected to the lifting platform 8-1 to drive the lifting platform 8-1 to move up and down. The translation cylinder 8-4 is fixedly mounted on the lifting platform 8-1. The long guide rail 8-5 is slidably disposed on the lifting platform 8-1 along the moving direction of the detector base 100 on the base assembly platform 7-1. The drive end of the translation cylinder 8-4 is connected to the long guide rail 8-5. Two sets of gripper mounting bases 8-6 are spaced apart on the long guide rail 8-5, and the pneumatic gripper 8-7 is mounted on the corresponding gripper mounting base 8-6. The pneumatic gripper 8-7 has two opposing grippers that can grip the outer periphery of the detector base 100 to achieve a grasping action.

[0051] like Figure 9As shown, the stacking mechanism includes a positioning core rod 7-5, a core rod lifting cylinder 7-6, a cylinder mounting plate 7-7, a connecting column 7-8, a baffle 7-9, and a pushing cylinder 7-10. The base assembly platform 7-1 is mounted on the platform 1-1 of the frame 1, forming a stacking space between the base assembly platform 7-1 and the platform 1-1. The base assembly platform 7-1 has a stacking hole 7-1-2, the size of which is slightly larger than the size of the detector base 100. The cylinder mounting plate 7-7 is connected via a connecting column 7-8. The connecting column 7-8 is fixed below the platform 1-1, the core rod lifting cylinder 7-6 is fixed on the cylinder mounting plate 7-7, the positioning core rod 7-5 is connected to the driving end of the core rod lifting cylinder 7-6, and the positioning core rod 7-5 is driven by the core rod lifting cylinder 7-6 to move telescopically within the stacking space; the baffle 7-9 is set on both sides below the stacking hole 7-1-2 to form a limiting slide, and the pushing cylinder 7-10 is set at one end of the limiting slide to push the stacked detector base 100 out along the limiting slide direction. When stacking, the positioning core rod 7-5 extends, so that the upper end of the positioning core rod 7-5 is located at the stacking hole 7-1-2. The base moving mechanism 8 can grab the detector base 100 on the base rotating positioning seat 7-2 and place it on the positioning core rod 7-5. When the positioning core rod 7-5 is stacked to a set height or quantity, the core rod lifting cylinder 7-6 drives the positioning core rod 7-5 to retract downward and be pulled out from the stacked detector base 100. Then the pushing cylinder 7-10 pushes the detector base 100 outward along the limit slide.

[0052] like Figure 8 As shown, in this embodiment, the pressing mechanism 9 includes a column 9-1, a mounting bracket 9-2, a pressing cylinder 9-3, and a pressing head 9-4. The mounting bracket 9-2 is fixedly mounted on the platform 1-1 via the column 9-1. The pressing cylinder 9-3 is fixed on the mounting bracket 9-2, and the pressing head 9-4 is mounted on the drive end of the pressing cylinder 9-3. After the component gripping mechanism 11 moves the terminal assembly 120 above the base rotation positioning seat 7-2, the pressing cylinder 9-3 actuates, causing the pressing head 9-4 to move downward. The pressing head 9-4 acts on the aforementioned pressing protrusion 11-5-1, pressing the terminal assembly 120 into the corresponding mounting groove 110 of the detector base 100.

[0053] In addition, in this embodiment, a controller 10 is provided on platform 1-1. The controller 10 can control the start and stop of the assembly machine and its motion parameters. The specific motion control can be achieved by using a PLC and corresponding sensors. This part is existing technology and is not an improvement of this utility model, so it will not be described in detail here.

[0054] This utility model discloses a detector base assembly machine, which adopts an alternative assembly sequence. First, the nut, spring plate, and screw are assembled into a terminal block assembly, and then the terminal block assembly is pressed onto the base as a whole. This eliminates the need for assembly on a multi-station rotary table, resulting in a simpler and more compact overall structure, smaller space occupation, simpler assembly operations, easier control, better assembly stability, and higher assembly efficiency.

[0055] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
