Description

Technical Field

[0001] The utility model relates to the technical field of relay assembly equipment, in particular to a material moving device used in a solid-state relay assembly production line. Background Art

[0002] Solid-state relays are contactless switches composed of microelectronic circuits, discrete electronic components, and power electronics. Existing solid-state relays rely on a combination of manual and mechanical assembly. On automated assembly lines, the parts required for solid-state relay assembly are small or thin, requiring precise positioning for both assembly and post-assembly testing. The current standard practice is to install multiple positioning mechanisms at each assembly and testing location on a conveyor belt, using gripping and handling components and conveyor belts to transport the solid-state relays. This assembly method presents the following issues: 1. The solid-state relay housing has a smooth surface and lacks grooves or other positioning structures, making it prone to deviation during handling and gripping, impacting subsequent processes. 2. The installation of multiple positioning mechanisms complicates the mechanical structure of the production line. Summary of the Invention

[0021] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, a material transfer device for a solid-state relay assembly production line includes a carrier 1, a feed conveyor belt 11, a discharge conveyor belt 16, a carrier return belt 14, a feed handling assembly A3, a solid-state relay discharge handling assembly 15, and a carrier return handling assembly 17. After the carrier 1 carries the solid-state relay housing, it is conveyed via the feed conveyor belt 11. The feed handling assembly A3 grabs and carries the carrier 1 together with the solid-state relay housing. The solid-state relay discharge handling assembly 15 grabs and carries the solid-state relay housing to the discharge conveyor belt 16. The carrier return handling assembly 17 grabs and carries the carrier 1 to the carrier return belt 14. When this material transfer device is applied to a solid-state relay assembly production line, corresponding assembly and testing mechanisms can be set up on the side of the feed conveyor belt 11 according to the requirements of processing, assembly, and testing, and multiple feed handling assemblies A3 can be set up to realize the transfer between the various mechanisms.

[0023] like Figure 2 As shown, the carrier 1 includes a first groove 2 for accommodating the solid-state relay housing 101, and a plurality of limiting ribs 3 are provided on the side walls of the first groove 2. A positioning column 4 is provided in the first groove 2. The positioning column 4 and the limiting rib 3 cooperate to ensure that the solid-state relay housing 101 will not shift when it is located in the first groove 2. The groove depth of the first groove 2 is less than the height of the solid-state relay housing 101, which is convenient for assembly and inspection. A plurality of positioning holes 5 are provided on the outside of the bottom of the carrier 1, which facilitates positioning during grasping without setting up a cumbersome positioning mechanism on the production line, which is conducive to simplifying the production line.

[0024] like Figure 3 As shown, the material feeding and handling assembly A3 includes a material picking claw A21, a first driving cylinder A22 for driving the material picking claw A21 to clamp or release, a slider guide cylinder assembly A23 for driving the material picking claw to move horizontally and vertically is provided on the side of the material picking claw A21, and a positioning protrusion A24 adapted to the positioning hole 5 is provided at the lower end of the material picking claw A21. When the material picking claw A21 grabs the carrier 1 and the solid-state relay housing 101, the positioning protrusion A24 is limited in the positioning hole 5 to prevent the carrier from shaking. A stop column is provided at the upper end of the material picking claw A21, which can limit the solid-state relay housing 101 from moving up and away from the carrier 1, thereby ensuring stable grabbing and handling.

[0025] The solid state relay discharge handling assembly 15 is arranged on the side of the discharge conveyor belt 16. Figure 4As shown, the solid-state relay discharging and handling assembly 15 includes a discharging and handling cross plate 21, a slider guide cylinder assembly 25 for driving the discharging and handling cross plate 21 to move horizontally and vertically, and two groups of claw assemblies are provided on both sides of the discharging and handling cross plate 21. The claw assembly includes a clamping claw 22 and a second driving cylinder 23 that drives the clamping claw 22 to clamp or release. In this embodiment, a silicone pad 24 is provided at the clamping position of the clamping claw. On the one hand, the silicone pad 24 can increase the friction between the clamping claw 22 and the solid-state relay housing 101, making the clamping and grasping more reliable. On the other hand, it can prevent the clamping force of the clamping claw 22 from being too large and damaging the solid-state relay housing 101. A first transfer rack 26 is provided between the gripper assembly and the discharge conveyor belt 16. The first transfer rack 26 is provided with a second groove 27 adapted to the solid-state relay housing 101. When using a horizontal plate double-hand gripper assembly structure for transportation, the gripper assembly on the left grabs the solid-state relay housing from the feed conveyor belt to the first transfer rack, while the other gripper assembly on the right synchronously grabs the solid-state relay housing 101 on the first transfer rack and transports it to the discharge conveyor belt 16, effectively shortening the movement path of the gripper assembly and improving efficiency.

[0026] The carrier return conveying assembly 17 is arranged on the side of the carrier return belt 14. Figure 5 As shown, the carrier reflux transport assembly 17 includes a carrier discharge transport cross plate 31, a slider guide cylinder assembly 35 that drives the carrier discharge transport cross plate 31 to move horizontally and vertically, and two sets of carrier discharge claw assemblies are provided on both sides of the carrier discharge transport cross plate 31. The carrier discharge claw assembly includes a carrier discharge claw 32 and a third driving cylinder 33 that drives the carrier discharge claw 32 to clamp or release. The carrier discharge claw 32 is wider than the clamping claw 22, which facilitates the secure grasping of the carrier 1. The carrier discharge claw 32 is provided with a silicone pad 34 at the clamping position. The silicone pad 24 can increase the friction between the carrier discharge claw 32 and the carrier 1 on the one hand, making the clamping and grasping more reliable, and on the other hand, it can prevent the carrier 1 from being damaged by excessive clamping force of the carrier discharge claw 32. A second transfer rack 36 is provided between the carrier discharging claw and the carrier return belt. The second transfer rack 36 is provided with a third groove 37 adapted to the carrier 1. Like the solid-state relay discharging and handling assembly 15, when the horizontal plate double-hand claw assembly structure is used for handling, the movement path of the claw assembly can be effectively shortened, thereby improving efficiency.

[0027] In this embodiment, the tail end of the carrier return belt 14 is connected to the starting end of the feed conveyor belt 11 through the storage tray 12. A pushing mechanism 13 is provided on the side of the storage tray 12. The returned carriers 1 are accumulated on the carrier return belt 14. After a certain number of them are arranged, the pushing mechanism 13 pushes them into the feed conveyor belt 11 to realize circulation and improve the degree of automation of the production line.

[0028] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
