[0025] The stamping station 12 has the stamping mechanism 3, is used for stamping the workpiece to be handled, the continuity testing station 13 has the continuity testing mechanism 5, is used for testing whether the PIN foot of the workpiece after stamping is conductive, the discharging station 14 has the discharging mechanism 6 for discharging the workpiece after testing.
[0026] Combined with reference Figures 1 to 4 As shown in the embodiment, the workbench 1 is used as the basic support platform, the rotating disc 2 is fixedly installed on the end face of the workbench 1 and can rotate along the circumferential direction. Four locating fixtures 21 are uniformly distributed on the end face of the rotating disc 2 close to the edge, to fix the workpiece to be handled. The workpiece to be handled is the humidity switch semi-finished product to be stamped. The end face of the workbench 1 is four-folded and sequentially arranged as the feeding station 11, the stamping station 12, the continuity testing station 13 and the discharging station 14. The bottom of the rotating disc 2 is provided with the drive structure 22 for driving the rotating disc 2 to rotate, so that each locating fixture 21 can accurately stay in each station in turn for corresponding process treatment.
[0027] The specific operation process is as follows: the operator faces the feeding station 11, accurately sends the workpiece to be handled into the locating fixture 21 rotating to the feeding station 11, ensures that the workpiece is stably placed, and prepares for subsequent processing. When the rotating disc 2 rotates to the stamping station 12, the stamping mechanism 3 stamps the workpiece in the locating fixture 21 staying in the station. Then, the locating fixture 21 continues to rotate to the continuity testing station 13, and the continuity testing mechanism 5 of the station is used to detect whether the PIN foot of the humidity switch is correctly conductive, and test whether the workpiece after stamping meets the electrical conduction requirement. The humidity switch workpiece that has completed all process treatments and passed the test will be removed from the rotating disc 2 by the discharging mechanism 6 through the mechanical arm, pneumatic device or other automatic mode at the discharging station 14, at the same time, the workpiece that does not pass the test will be sent into the storage box of the discharging station 14 for collection.

The automation feature makes the production process more stable and accurate, and can efficiently complete the batch production and quality detection of the humidity switch, reduce manual operation, and improve production efficiency and product quality.
[0029] In a possible implementation, the stamping mechanism 3 includes a first support frame 31 fixed to the workbench 1, an upper punch 32 located directly above the positioning jig 21, and a first driving member 33 fixed to the first support frame 31, which is drivingly connected to the upper punch 32 for driving the upper punch 32 to move along the Z-axis direction to stamp the workpiece to be processed.
[0030] For reference Figure 1 and Figure 2 In the embodiment, the first support frame 31 is fixedly installed in the stamping station 12 of the workbench 1. The upper punch 32 is located directly above the positioning jig 21 rotated to the stamping station 12, and the upper punch 32 and the side surface of the first support frame 31 are provided with a Z-axis guide structure to ensure the centering accuracy between the upper punch 32 and the workpiece to be processed during stamping, avoiding offset or misalignment. The vertical movement of the upper punch 32 is driven by a cylinder fixed to the top of the first support frame 31. The cylinder as the driving member of the embodiment drives the upper punch 32 to move accurately along the Z-axis direction, thereby realizing the vertical stamping operation on the workpiece in the positioning jig 21.
[0031] In a possible implementation, the stamping station 12 further has a limiting assembly 4 for supporting the rotary table 2 during stamping. The limiting assembly 4 includes a top block 41 located below the rotary table 2 and a second driving member 42 drivingly connected to the top block 41 for driving the top block 41 to rise to abut against the bottom of the rotary table 2.
[0032] For reference Figure 1 and Figure 2 In the embodiment, the stamping station 12 further has a limiting assembly 4, which includes a driving cylinder and a top block 41 connected to the cylinder. The initial position of the top block 41 is located below the rotary table 2 and corresponds to the position of the upper punch 32. Before stamping, the top block 41 is first driven by the second driving member 42 to rise, contacts and supports the bottom of the rotary table 2, ensuring that the rotary table 2 is stably fixed during stamping. Then the upper punch 32 is driven by the first driving member 33 to descend to perform the stamping operation. After stamping, the first driving member 33 and the second driving member 42 drive the upper punch 32 and the top block 41 to reset, respectively. This design effectively supports the rotary table 2 during stamping to prevent the workpiece from sinking due to uneven force, thereby avoiding the occurrence of poor stamping.
[0033] In a possible implementation, the continuity testing mechanism 5 includes a second support frame 51 fixed on the workbench 1, a lifting seat 52 arranged on the second support frame 51, a third driving member 53 for driving the lifting seat 52 to lift, a brushless electric screwdriver 54 arranged on the lifting seat 52 for screwing a screw on the workpiece, and a detection probe 55 for contacting a PIN pin on the workpiece.
[0034] In combination with reference to Figure 1 and Figure 3 In this embodiment, the second support frame 51 serves as a support structure of the continuity testing mechanism 5, and a lifting seat 52 driven to lift by the third driving member 53 is arranged on the side of the second support frame 51 close to the turntable 2. The brushless electric screwdriver 54 and multiple probes are arranged on the lifting seat 52. When the positioning jig 21 after the stamping process rotates to the position directly below the lifting seat 52, the lifting seat 52 is driven to lower by the third driving member 53, and each probe contacts the PIN pin of the workpiece. At the same time, the servo motor at the top of the second support frame 51 drives the brushless electric screwdriver 54 to rotate the adjusting screw in the middle of the workpiece, so that the probe receives the conductive signal between the PIN pins (such as COM and NC pins) of the humidity switch. After the test is completed, the servo motor is reversed to a fixed angle, the servo motor stops rotating, the third driving member 53 is reset, and the continuity testing is completed.
[0035] In a possible implementation, the unloading mechanism 6 includes an unloading chute 64 arranged on the workbench 1, a third support frame 61 arranged beside the unloading chute 64, a clamping assembly 62 arranged on the third support frame 61 for clamping the workpiece, and a moving assembly 63 drivingly connected to the clamping assembly 62 for moving the clamped workpiece from the positioning jig 21 to the unloading chute 64.
[0036] In combination with reference to Figure 1 and Figure 4 In this embodiment, the unloading station 14 is equipped with an unloading chute 64 with a certain inclination, and the end of the unloading chute 64 is connected to a workpiece collection box. The third support frame 61 is arranged beside the unloading chute 64 to provide stable support for the clamping assembly 62. The clamping assembly 62 is responsible for clamping and fixing the workpiece, and adopts a pneumatic, mechanical or electric driving mode, which can realize accurate clamping force control, thereby effectively avoiding damage to the workpiece during movement. The moving assembly 63 is drivingly connected to the clamping assembly 62, and can drive the clamping assembly 62 to move the workpiece from the positioning jig 21 to the unloading chute 64. The driving device can adopt a motor, an air cylinder or other types of driving systems, and has adjustable speed and precision, to ensure that the workpiece can be accurately and smoothly moved to the predetermined position. Through automatic unloading and workpiece transmission, manual intervention is reduced, and production efficiency and precision are significantly improved, while ensuring that the workpiece is safely and efficiently processed throughout the process.
[0037] In a possible implementation, the unloading station 14 further comprises a beryllium copper knocking assembly 7, which comprises a knocking flat plate 71, a fourth driving member 72 connected to the knocking flat plate 71 for driving the knocking flat plate 71 to move to the entrance of the unloading slide 64, and a fifth driving member 73 connected to the clamping assembly 62 for driving the workpiece to be knocked by the knocking flat plate 71 for several times.
[0038] With reference to Figure 1 and Figure 4 In the embodiment, the beryllium copper knocking assembly 7 is designed to enable the workpiece to be mechanically knocked when passing through the unloading station 14 to knock the beryllium copper conductive member of the humidity switch. Specifically, a cylinder is arranged beside the unloading slide 64 as the fourth driving member 72, and the rod part of the cylinder is connected to a knocking flat plate 71, which can move to the entrance of the unloading slide 64 under the driving of the cylinder. Meanwhile, a beryllium copper knocking cylinder is arranged on the third support frame 61 for driving the clamping assembly 62 to move up and down. When the clamping assembly 62 is driven by the third driving member 53 to move the workpiece above the knocking flat plate 71, the beryllium copper knocking cylinder is driven to move up and down repeatedly twice, so that the workpiece knocks the knocking flat plate 71. After the knocking is completed, the third driving member 53 drives the knocking flat plate 71 to reset, and the clamping assembly 62 releases the workpiece, so that the workpiece falls to the unloading slide 64. Thus, the beryllium copper knocking and unloading processes are completed successfully.
[0039] In a possible implementation, a detection sensor 23 is arranged at the middle position of the rotating disc 2 for detecting whether a workpiece is placed in each positioning jig 21. Specifically, the detection sensor 23 can detect the state of each positioning jig 21 in real time to determine whether a workpiece is placed therein, thereby avoiding errors or omissions caused by manual inspection and improving the production efficiency and accuracy.
[0040] In a possible implementation, the driving structure 22 comprises a cam divider 221 and a driving motor 222 arranged below the rotating disc 2 and drivingly connected thereto. The cam divider 221 can provide uniform and accurate rotation indexing, so that the rotating disc 2 can be accurately controlled to rotate according to a preset step distance or angle.
[0041] The above-described embodiments are only preferred embodiments of the utility model, and cannot be used to limit the protection scope of the utility model.
