[0034] The probe fixture 8 includes a base 801, which is detachably mounted and assembled with a sliding seat 7. The base 801 has a recessed mounting groove 802 with openings at both ends. One opening end of the mounting groove 802 faces the core seat and is fitted with a mounting block 803. Multiple probes 10 are threaded through the mounting block 803. The base 801 has a mounting position 804, which is connected to the other opening of the mounting groove 802. The mounting position 804 has multiple metal connecting blocks 805. One end of each probe 10 extends into the mounting groove 802 and is connected to each metal connecting block 805 via a connecting wire. The end extending out of the mounting groove 802 is used to contact and conduct electricity with the pin of a micro switch.

[0035] Furthermore, the mounting block 803 is also provided with multiple push rods 806, which are spaced apart from the multiple probes 10 and extend towards the core seat to push the core seat of the micro switch. In addition, the probe fixture 8 also includes a top cover 807, which is fixed to the base 801 by bolts 808 to seal the mounting groove 802. The two side walls of the mounting groove 802 are also provided with first slots 809 near the mounting block 803, and both first slots 809 are connected to the mounting groove 802.

[0036] The main control system controls the assembly drive component to drive the assembly slide seat 7 to slide along the assembly axis 6, which in turn drives the probe fixture 8 to slide, moving the assembly end 801 to the micro switch on the product fixture 4, until the probe 10 on the assembly end 801 contacts and conducts with the pin of the micro switch.

[0037] like Figure 5 As shown, the push rod mechanism includes a push rod shaft 11, a push rod sliding seat 12, a push rod drive assembly (not shown), and a pressing rod 13.

A third fixed seat 14 is mounted on the push rod sliding seat 12, and the pressing rod 13 is mounted on the third fixed seat 14, extending towards the product fixture 4 to press the pressing point (i.e., button 203) of the micro switch 200. Furthermore, a pressure sensor 15 is also mounted on the third fixed seat 14, the pressing rod 13 is connected to the pressure sensor 15, and the pressure sensor 15 is communicatively connected to the main control system to sense the pressure of the pressing rod 13.

[0038] The main control system controls the push rod drive assembly to drive the push rod sliding seat 12 to slide along the push rod shaft 11, which in turn drives the pressing rod 13 to slide, so that the pressing rod 13 presses on the pressing point (i.e., button 203) of the micro switch 200 on the product fixture 4. The pressure sensor 15 detects the pressure of the pressing rod 13 and sends the signal to the main control system for real-time monitoring to ensure the assembly accuracy of the micro switch.

[0039] The assembly drive components and push rod drive components can be cylinders paired with telescopic rod modules or motors paired with lead screw modules, and are not limited to these.

[0040] For ease of operation, the chassis 1 is also provided with a worktable 100, and the worktable 100 has an opening 101, through which the probe 10, the pressing rod 13 and the product fixture 4 are exposed.

[0041] In addition, the mounting panel 2 is equipped with a first reading head 16 and a second reading head (not shown). The first reading head 16 is correspondingly set to the assembly shaft 6, and the second reading head is correspondingly set to the push rod shaft 11. Both the first and second reading heads are communicatively connected to the main control system. The first reading head 16 is used to record the movement distance of the assembly slide seat 7 along the assembly shaft 6, and the second reading head is used to record the movement distance of the push rod slide seat 12 along the push rod shaft 11. The chassis 1 is also equipped with a protective cover 17 and a start switch 18.

[0042] In addition, the push rod sliding seat 12 is provided with a left and right moving guide rail 19, and the pressing rod 13 is slidably installed on the left and right moving guide rail 19. The position of the pressing rod 13 is finely adjusted by the left and right moving guide rail 19 so that the pressing rod 13 is aligned with the button 203 of the micro switch 200. The assembly platform 3 is provided with two bellows covers 20. One bellows cover 20 is located between the first fixed seat 5 and the assembly sliding seat 7, and its two ends are connected to the first fixed seat 5 and the assembly sliding seat 7 respectively. The other bellows cover 20 is located between the first fixed seat 5 and the push rod sliding seat 12, and its two ends are connected to the first fixed seat 5 and the push rod sliding seat 12 respectively. The two bellows covers 20 can be contracted and extended as the assembly sliding seat 7 and the push rod sliding seat 12 move to ensure that no impurities fall into the housing 1 during the micro switch installation process.

[0043] like Figure 1 and Figure 2 and Figure 6 As shown, the working process of the assembly equipment for micro switches of this utility model is as follows:

[0044] (1) The operator places the micro switch core and the product into the product fixture 4; the product fixture 4 is then installed on the first fixed base 5 and fixed by magnetic attraction.

[0045] (2) The operator installs the probe fixture 8 onto the second fixed base 9, tightens it with screws, and then removes the protective cover 17;

[0046] (3) The operator inputs the model information of the product to be tested (i.e., micro switch 200) into the main control system and presses the start button 18. The main control system controls the probe assembly mechanism and the push rod mechanism to start the assembly action.

[0047] (4) The main control system controls the assembly drive component to drive the assembly sliding seat 7 to slide along the assembly axis 6, which in turn moves the probe fixture 8, so that the probe 10 on the mounting block 801 contacts and conducts with the pin 204 of the product. The initial position of the assembly is marked by the first reading head 16.

[0048] (5) The main control system controls the push rod drive assembly to drive the push rod sliding seat 12 to slide along the push rod shaft 11, thereby moving the pressing rod 13 so that the pressing rod 13 presses onto the pressing point of the product (i.e., button 203), where the second reading head marks the initial pressing position.

[0049] (6) The main control system controls the push rod drive assembly to drive the push rod sliding seat 12 to continue sliding along the push rod shaft 11, and continue to advance the rated distance from the initial pressing position so that the pressing rod 13 reaches the rated force. At this time, the moving distance data of the push rod sliding seat 12 is fed back to the main control system through the second reading head. The pressing force of the pressing rod 13 is monitored in real time by the pressure sensor 15 to ensure accuracy.

[0050] (7) The main control system controls the assembly drive component to drive the assembly slide seat 7 to slide along the assembly axis 6 and continue to slide. It continues to advance the rated distance from the initial assembly position, driving the push rod 805 of the probe fixture 8 to advance the core seat 202 of the product (i.e., the micro switch 200) by the corresponding distance. The main control system monitors whether the micro switch 200 is conducting in real time. If the assembly slide seat 7 is still not conducting after moving the corresponding distance, the main control system controls the assembly slide seat 7 to continue to advance the rated distance until the product is conducting and then stops. At this time, the moving distance data of the assembly slide seat 7 is fed back to the main control system through the first reading head 16.

[0051] (8) After the micro switch 200 is assembled, the main control system controls the assembly slide seat 7 and push rod slide seat 12 to reset, opens the protective cover 17, removes the product fixture 4, and the assembly process is completed.

[0052] In summary, the assembly equipment for micro switches of this utility model is connected to the main control system through the installation mechanism and the push rod mechanism. The main control system controls the installation mechanism and the push rod mechanism to assemble the micro switches on the product fixture 4, thereby realizing the automatic assembly of micro switches, effectively improving production efficiency and reducing production costs. At the same time, during the assembly process, the pressure sensor 15 monitors the pressing force of the pressing rod 13 in real time, effectively improving the assembly accuracy, realizing high-precision assembly, and improving product stability.
