[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0055] To achieve the above objectives, the technical solution of this utility model is as follows:

[0056] See Figure 1 As shown, this embodiment provides a spring assembly device, including:

[0057] Product conveying mechanism 1 for loading and unloading products;

[0058] Spring conveying mechanism 2 is used to load springs;

[0059] Spring detection mechanism 3 for realizing spring detection;

[0060] 4. Robotic assembly mechanism for product transfer and spring assembly;

[0061] 5. Positioning and testing organization used for product positioning and testing;

[0062] The product conveying mechanism 1, spring conveying mechanism 2, spring detection mechanism 3, and robotic arm assembly mechanism 4 are arranged around the positioning and detection mechanism 5.

[0063] In this application, after the product conveying mechanism 1 conveys the product to the predetermined position, the robotic arm assembly mechanism 4 picks up the product and transfers it to the positioning and detection mechanism 5 for positioning. The spring conveying mechanism 2 conveys the spring to the predetermined position. After the spring detection mechanism 3 detects the spring, it sends a signal to the robotic arm assembly mechanism 4. After receiving the signal, the robotic arm assembly mechanism 4 picks up the spring. The spring detection mechanism 3 checks whether the spring picked up by the robotic arm assembly mechanism 4 meets the assembly requirements. If it does not meet the requirements, it picks up the spring again. If it meets the requirements, it assembles the spring into the product of the positioning and detection mechanism 5. After the spring is assembled, the positioning and detection mechanism 5 detects the assembled product. If the detection is qualified, it is transferred to the material tray 6 of the product conveying mechanism 1 for unloading. If it is unqualified, it is transferred to the NG material tray 6 of the product conveying mechanism 1.

[0064] Further, see Figure 2-3 The product conveying mechanism 1 includes:

[0065] Two parallel product conveyor belt assemblies 11;

[0066] A belt spacing adjustment module 12 for adjusting the width between the two product conveyor belt assemblies 11;

[0067] Both product conveyor belt assemblies 11 are mounted on the belt spacing adjustment module 12.

[0068] Furthermore, the belt spacing adjustment module 12 includes a first side plate 121, a second side plate 122, a support assembly 123, a lead screw 124, an adjustment handwheel 125, and a lead screw nut seat 126. The first side plate 121 and the second side plate 122 are arranged side by side with the product conveyor belt assembly 11 in the same direction, and the first side plate 121 and the second side plate 122 are connected by the support assembly 123. The two ends of the lead screw 124 are respectively passed through and rotatably mounted on the first side plate 121 and the second side plate 122. The adjustment handwheel 125 is fixedly mounted on one end of the lead screw 124. Both product conveyor belt assemblies 11 are supported on the support assembly 123, and one of the product conveyor belt assemblies 11 is connected to the lead screw 124 through the lead screw nut seat 126.

[0069] In this application, the product is placed in a tray 6, which is positioned between two product conveyor belt assemblies 11 and supported by the product conveyor belt assemblies 11. The product conveyor belt assemblies 11 rotate under the drive of a motor, thus conveying the product tray 6. The lead screw 124 can be rotated by turning the adjusting handwheel 125 at one end. The two ends of the lead screw 124 remain stationary. Based on the principle of the lead screw 124, the lead screw nut seat 126 will move on the lead screw 124, thereby causing one product conveyor belt assembly 11 to move relative to the other product conveyor belt assembly 11, adjusting the distance between the two product conveyor belt assemblies 11 to accommodate trays 6 of different widths.

[0070] Furthermore, the product conveying mechanism 1 also includes a limiting lifting module 13, which includes a lifting connecting plate 131, a lifting position sensor 132, and a lifting cylinder 133. The two ends of the lifting connecting plate 131 are respectively fixed to the first side plate 121 and the second side plate 122. The lifting position sensor 132 and the lifting cylinder 133 are both mounted on the lifting connecting plate 131. When the material tray 6 is conveyed to a predetermined position, it can be detected by the lifting position sensor 132. At this time, the product conveyor belt assembly 11 stops operating, and the output end of the lifting cylinder 133 extends to block and limit the material tray 6, facilitating the robotic arm assembly mechanism 4 to pick up and release materials.

[0071] Further, see Figure 4-6 The spring conveying mechanism 2 includes a linear vibrating plate 21 and a flexible vibrating plate 22, which are connected in sequence. The spring detection mechanism 3 includes a spring profile detection camera 31, which is positioned above the flexible vibrating plate 22.

[0072] Furthermore, the spring detection mechanism 3 also includes a spring state detection camera 32 for detecting whether the spring grasped by the robotic arm assembly mechanism 4 meets the assembly requirements.

[0073] In this application, the spring is placed in the linear vibrating plate 21. The vibration of the linear vibrating plate 21 transfers the spring to the flexible vibrating plate 22. When the spring profile detection camera 31 detects that there is a spring in the flexible vibrating plate 22, it transmits a signal to the control host. The control host sends a signal to the robot assembly mechanism 4. After receiving the signal, the robot assembly mechanism 4 grabs the spring and moves it to the spring status detection camera 32. The spring status detection camera 32 will detect whether the spring grabbed by the robot meets the assembly requirements. If it does not meet the requirements, it will grab the spring again. If it does meet the requirements, it will be assembled.

[0074] Further, see Figure 7 The robotic arm assembly mechanism 4 includes:

[0075] The robotic arm body 41 has a mounting plate 42;

The spring lifting slider 433 is slidably connected to the spring lifting slide rail 432 and connected to the output end of the spring lifting cylinder 431. The spring gripper cylinder 434 is connected to the spring lifting slider 433, and the spring gripper 435 is connected to the output end of the spring gripper cylinder 434.

[0080] In this application, the spring gripper cylinder 434 can control the opening and closing of the spring gripper 435 to grip the spring and assemble the spring into the product. The spring lifting cylinder 431 adjusts the vertical height of the spring gripper 435 by pushing the spring lifting slider 433 to move on the spring lifting slide rail 432.

[0081] Furthermore, the product gripping module 44 includes a product lifting cylinder 441, a product lifting slide rail 442, a product lifting slider 443, a product gripper cylinder 444, and a product gripper 445. The product lifting cylinder 441 and the product lifting slide rail 442 are both fixed on the same side of the mounting plate 42. The product lifting slider 443 is slidably connected to the product lifting slide rail 442 and connected to the output end of the product lifting cylinder 441. The product gripper cylinder 444 is connected to the product lifting slider 443, and the product gripper 445 is connected to the output end of the product gripper cylinder 444.

[0082] In this application, the product gripper cylinder 444 can control the opening and closing of the product gripper 445 to grip the product and realize the transfer of the product. The product lifting cylinder 441 adjusts the vertical height of the product gripper 445 by pushing the product lifting slider 443 to move on the product lifting slide rail 442.

[0083] Further, see Figure 10-11 The positioning detection mechanism 5 includes:

[0084] Mounting bracket 51;

[0085] Product positioning module 52 for positioning products;

[0086] 53, a finished product inspection camera used to check whether finished products meet the requirements;

[0087] Translation module 54 used to adjust the position of product positioning module 52;

[0088] The translation module 54 and the finished product inspection camera 53 are both mounted on the mounting bracket 51. The product positioning module 52 is mounted on the translation module 54, and the finished product inspection camera 53 is positioned above the product positioning module 52.

[0089] Furthermore, the translation module 54 includes a translation cylinder 541, a translation slide rail 542, and a translation slider 543. The translation cylinder 541 and the translation slide rail 542 are mounted on the mounting bracket 51. The translation slider 543 is slidably connected to the translation slide rail 542 and is connected to the output end of the translation cylinder 541. The product positioning module 52 is connected to the translation slider 543.

[0090] Furthermore, the product positioning module 52 includes a positioning support plate 521, a positioning fixture 522, and a positioning cylinder 523. The positioning fixture 522 and the positioning cylinder 523 are mounted on the positioning support plate 521. The positioning fixture 522 is provided with a product positioning groove 524 with a notch at one end, and the positioning cylinder 523 is located on the side where the notch of the product positioning groove 524 is located.

[0091] In this application, when the product gripper 445 places the gripped product into the product positioning groove 524, the output end of the positioning cylinder 523 extends in, holding the product against the product positioning groove 524 to achieve product positioning. The translation cylinder 541 can drive the positioning fixture 522 to move via the translation slider 543, adjusting the product position for easy operation by the robot arm. After the spring assembly is completed, the finished product inspection camera 53 can detect whether the spring assembly meets the requirements. If it meets the requirements, the product gripper 445 grips the product and places it in the material tray 6 for unloading; if it does not meet the requirements, the product is placed in the NG material tray 6 for unloading.

[0092] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
