[0001] This utility model belongs to the field of automation equipment technology, and in particular relates to an automatic assembly, unloading and inspection line for spring sheets. Background Technology

[0002] Microswitches and push-button switches utilize switch springs with contacts to ensure normal contact performance, improve reliability, and prevent intermittent contact issues after prolonged use. Currently, after the switch spring and contact are crimped together, a rotary pneumatic gripper mechanism places the crimped assembly onto a conveyor belt for outflow and collection. The crimped assembly is then individually inspected for quality, resulting in low production efficiency and the need for external inspection personnel. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a mechanism for automatically detecting the conformity of the spring and contact crimping assembly when it flows out of the conveyor belt for unloading.

[0015] Figure 3 yes Figure 2 Enlarged structural diagram at point M. Detailed Implementation

[0016] The present invention will now be described in detail with reference to specific embodiments:

[0017] like Figures 1 to 3 The automatic assembly and unloading inspection line for spring sheets shown includes a gripper mechanism 1, a conveyor platform 2, a belt conveyor 3, a cover plate 4, a receiving box 5, a base 50, a slide rail 52, an inspection mechanism, and a control module. The gripper mechanism 1 and the belt conveyor 3 are both mounted on the conveyor platform 2. The cover plate 4 is fixedly mounted on the top of the conveyor platform 2, and there is a gap 41 between the bottom surface of the cover plate 4 and the top surface of the belt of the belt conveyor 3.

[0018] The testing mechanism consists of a switch base 6, a contact rod 7, a limiting plate 71, a guide rod 72, a spring 73, a top cover 8, and a touch switch 9. The switch base 6 is fixedly mounted on the cover plate 4. The top of the switch base 6 has a groove, and the switch base 6 and the cover plate 4 are fitted with a through hole. The contact rod 7 is slidably mounted in the through hole. The bottom of the contact rod 7 is designed with a spherical structure. The spherical structure of the bottom of the contact rod 7 can reduce the resistance to contact with the contact point of the defective product, making the upward movement of the contact rod smoother. The limiting plate 71 is fixedly sleeved on the... On the guide rod 72, the top cover 8 is fixedly installed on the top of the switch base 6 to seal the groove. The four guide rods 72 are fixedly installed in the groove in a rectangular distribution. The spring 73 is sleeved on the guide rod 72. The bottom surface of the top cover 8 also presses against the top of the guide rod 72. The upper and lower ends of the spring 73 act on the top cover 8 and the limiting plate 71 respectively. Under the action of the spring force of the spring 73, the limiting plate 71 presses against the bottom of the groove. The touch switch 9 is fixedly installed on the bottom surface of the top cover 8. The contact rod 7 contacts the contact of the touch switch 9.

[0019] The slide rail 52 is fixedly installed on the base 50. The two receiving boxes 5 are slidably installed on the slide rail 52 by sliders. The two receiving boxes 5 are fixedly connected. One of the receiving boxes 5 is equipped with a drive walking mechanism.

[0020] The touch switch 9 and the driving mechanism are connected to the control module via circuits. The driving mechanism consists of a gear and rack 53 and a drive motor that drives the trolley. The trolley is fixedly installed at the bottom of one of the receiving boxes 5, and the rack 53 is fixedly installed on the base 50.

[0021] A positioning sleeve 81 is fixedly installed on the bottom surface of the top cover 8. The top of the guide rod 72 is slidably embedded in the positioning sleeve 81, and the upper end of the spring 73 acts on the bottom surface of the positioning sleeve 81. The positioning sleeve 81 can restrict the radial degree of freedom of the top of the guide rod 72, thereby improving the stability of the guide rod 72 installation structure.

[0022] A contact plate 70 is fixedly provided at the top of the contact rod 7. The contact plate 70 is configured as a disc-shaped structure. The diameter of the contact plate 70 is twice the diameter of the contact rod 7. The contact plate 70 increases the contact area with the contact of the touch switch 9, thereby improving the reliability of the contact of the touch switch 9.

[0023] The top of the receiving box 5 is fixedly and inclined with a U-shaped guide plate 51. The U-shaped guide plate 51 can play a guiding and buffering role, which can reduce the falling height of the spring and contact riveting assembly 10 and protect the product.

[0024] The rotary pneumatic gripper mechanism 1 clamps the automatically assembled spring and contact crimping assembly 10 and places it on the belt of the belt conveyor 3. The spring and contact crimping assembly 10 flows into the gap 41 along the belt conveyor 3. When the spring and contact crimping assembly 10 is a qualified product, the top surface of the contact slides against the bottom surface of the contact rod 7 and continues to flow backward until the material falls into the qualified product receiving box 5. When there is a product where the contact is not fully pressed into the hole of the spring, or when the height of the contact is too high, after the contact contacts the bottom surface of the contact rod 7, the contact pushes the assembly of the contact rod 7 and the limit plate 71 to overcome the elastic force of the spring 73 and move upward. The contact rod 7 squeezes the contact of the touch switch 9 to make it act and send an electrical signal to the control module. Since the belt conveyor line 3 operates intermittently, the control module uses a counting principle to control the drive mechanism to move the receiving box 5 when the qualified product is unloaded and the next product is unqualified. This moves the unqualified product receiving box 5 to the end of the belt conveyor line 3, where the unqualified spring and contact crimping assembly 10 falls into the unqualified product receiving box 5. The control module then switches the positions of the two receiving boxes 5 according to whether the next product is qualified.
