Description

Technical Field

[0001] This invention relates to the field of automated equipment, and more particularly to a flexible component assembly device. Background Technology

[0002] Figure 10 The elastic components include a fixed plate and a spring. When installing this elastic assembly, the fixed plate needs to be adjusted to a suitable tilt angle to facilitate gripping by the robotic arm.

[0003] The existing method for adjusting the tilt angle of the fixing plate involves setting several tilted positioning slots on a tray. Elastic components are manually placed into these slots to adjust the plate's tilt angle. However, when placing the elastic components into the slots, the fixing plate may not accurately fit against the slot walls, or it may even become stuck in the middle of the slot, with the bottom of the fixing plate wedged against the tilted wall. This results in poor positioning accuracy and consequently, poor assembly quality.

[0004] Therefore, there is a need to design a flexible component assembly equipment and an electronic product assembly line, which can help improve assembly quality. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible component assembly equipment and an electronic product assembly line, which can help improve assembly quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A flexible component assembly device, comprising:

[0008] A transfer device has a T-shaped placement slot, which includes a first groove for placing a fixing plate for an elastic component and a second groove for placing a spring; the first groove is connected to the second groove, the width of the first groove is greater than the thickness of the fixing plate, and the first groove is inclined to the first groove wall of the second groove, and a gas flow hole is provided on the first groove wall, which is connected to a gas collection and release device.

[0009] When the elastic component is placed in the T-shaped placement groove, the gas receiving and releasing device first sprays air along the gas flow hole to make the bottom of the fixing plate abut against the bottom of the second groove, and then draws air along the gas flow hole to make the fixing plate fit against the wall of the first groove, thereby causing the spring located in the first groove to be tilted.

[0010] Optionally, the elastic component assembly equipment further includes a first installation robot; the first installation robot includes a suction head, the suction head having an adsorption surface that is inclined to adsorb and adhere to the fixing plate of the first groove wall, and the suction head is provided with a pressing reinforcing rib for pressing the adsorbed elastic component into a set installation position.

[0011] Optionally, the elastic component assembly equipment further includes a second installation robot mounted on one side of the first installation robot, the second installation robot being provided with a protective pressure plate, and the protective pressure plate being vertically arranged;

[0012] The second installation robot moves the protective pressure plate to a first position, and the first installation robot moves the adsorbed elastic component to a second position, thereby compressing the elastic component between the suction head and the protective pressure plate. The second installation robot moves the protective pressure plate away so that the spring is inserted into the set mounting hole of the workpiece.

[0013] Optionally, the first installation robot arm further includes a stop post with an adjustable position;

[0014] During the process of the first installation robot moving the adsorbed elastic component to the second position, the stop post presses against the top of the spring.

[0015] Optionally, the flexible component assembly equipment also includes a feeding module and a material inspection module;

[0016] The feeding module includes a feeding robot and a feeding tray, the inspection module includes a first CCD detection camera located at the bottom of the movement trajectory of the feeding robot, and the feeding robot also includes grippers for clamping the fixed plate.

[0017] The loading robot is also used to place the gripped elastic components into the T-shaped placement slot.

[0018] Optionally, the flexible component assembly equipment also includes a conveyor belt assembly and a lifting device installed on one side of the bottom of the conveyor belt assembly to lift the workpiece to a set assembly station;

[0019] The conveyor belt assembly includes a first conveyor belt and a second conveyor belt spaced apart, and the lifting device is disposed between the first conveyor belt and the second conveyor belt.

[0020] Optionally, the flexible component assembly equipment also includes a quality inspection CCD camera;

[0021] The quality inspection CCD camera is located on one side of the bottom of the conveyor belt assembly, and the set assembly station and the quality inspection CCD camera are spaced apart along the conveying direction of the conveyor belt assembly.

[0022] Optionally, the flexible component assembly equipment also includes an NG robot arm disposed on one side of the quality inspection CCD inspection camera;

[0023] The quality inspection CCD camera and the NG robot are electrically connected. When the quality inspection CCD camera detects a product that is not installed correctly, the NG robot moves the product to the NG conveyor belt.

[0024] Optionally, the angle between the first tank wall and the horizontal plane is 3°.

[0025] An electronic product assembly line includes flexible component assembly equipment as described in any of the preceding claims.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In this embodiment, when the elastic component is placed on the T-shaped placement slot, the gas collection and release device sprays air, causing the bottom of the fixing plate to be pushed by the airflow. Under the action of gravity and airflow force, the fixing plate slides down along the first slot wall to the bottom of the first groove, and the spring can be more accurately located in the second groove. Then, the gas collection and release device draws in air under negative pressure, causing the fixing plate to fit completely against the first slot wall, thereby effectively improving the placement accuracy of the fixing plate, which is beneficial to improving the subsequent assembly quality.

[0042] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0043] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] This invention provides an assembly device for elastic components, which can help improve the assembly quality of elastic components.

[0046] Please see Figures 1 to 11 The flexible component assembly equipment 9 includes:

[0047] The transfer device 1 has a T-shaped placement slot, which includes a first groove 11 for placing a fixing plate 100 for an elastic component and a second groove 12 for placing a spring 200. The first groove 11 connects to the second groove 12. The width of the first groove 11 is greater than the thickness of the fixing plate 100, and the first groove 11 is inclined to the first groove wall 101 of the second groove 12. A gas flow hole 13 is provided on the first groove wall 101, which is connected to a gas collection and release device. The elastic component can be a positive spring and a structure of the fixing plate 100. The fixing plate 100 can be a metal plate or an insulating plate.

[0048] When the elastic component is placed in the T-shaped placement slot, the gas receiving and releasing device first sprays gas along the gas flow hole 13 to make the bottom of the fixing plate 100 abut against the bottom of the second groove 12, and then draws air along the gas flow hole 13 to make the fixing plate 100 and the first groove wall 101 fit together, thereby making the spring 200 located in the first groove 11 tilted.

[0049] Specifically, after blowing and inhaling, the elastic component is equivalent to undergoing a process of moving forward and then backward. During the forward and backward movement, the bottom of the fixing plate 100 is less likely to get stuck on the inclined first groove wall 101. The bottom of the fixing plate 100 can more accurately abut against the bottom of the first groove 11. In addition, the fixing plate 100 fits against the first groove wall, thereby improving the positioning accuracy of the elastic component.

[0050] Preferably, the width of the first groove 11 is generally no more than three times the thickness of the fixing plate 100.

[0051] Optionally, the elastic component assembly equipment further includes a first installation robot 2; the first installation robot 2 includes a suction head 21, which has an suction surface 201 that is inclined to adsorb and conform to the fixing plate 100 of the first groove wall 101, and the suction head 21 is provided with a pressing reinforcing rib 22 for pressing the adsorbed elastic component into a set installation position. It should also be noted that the suction surface 201 can be a combination structure of two or more planes to better adsorb and position the elastic component.

[0052] Specifically, the tilt angle of the adsorption surface 201 is consistent with the tilt angle of the fixed plate 100 positioned in the T-shaped placement slot, so that the adsorption surface 201 can better adsorb the elastic component and position the elastic component. In this embodiment, the first installation robot 2 is used to install the elastic component, which can help improve the installation efficiency of the elastic component. It should also be noted that in the assembly process of some electronic devices, the installation space reserved for the elastic component is small. The tilted adsorption surface 201 makes the spring 200 tilted during installation, which allows the spring 200 to be tilted and pressed into a narrower space to complete the assembly, which helps to reduce the overall size of the electronic device.

[0053] Optionally, the elastic component assembly equipment further includes a second mounting robot 3 mounted on one side of the first mounting robot 2. The second mounting robot 3 is equipped with a protective pressure plate 301, which is vertically positioned. The second mounting robot 3 moves the protective pressure plate 301 to a first position, while the first mounting robot 2 moves the adsorbed elastic component to a second position, thereby compressing the elastic component between the suction head 21 and the protective pressure plate 301. In this embodiment, the second mounting robot 3 moves the protective pressure plate 301 to the first position, where it adheres to the workpiece surface to protect it and prevent damage during the spring 200's insertion. The first mounting robot 2 moves the adsorbed elastic component to the second position, compressing the elastic component between the suction head 21 and the protective pressure plate 301. Then, the second mounting robot 3 moves the protective pressure plate 301 away, allowing the spring 200 to insert into the designated mounting hole on the workpiece. The workpiece is typically the casing of an electronic device, such as a smartwatch or mobile terminal.

[0054] Optionally, the first installation robot 2 also includes an adjustable stop post 23; during the process of the first installation robot 2 moving the adsorbed elastic component to the second position, the stop post 23 presses against the top of the spring 200. During this process, the stop post 23 presses against the top of the spring 200, ensuring that the centerline of the spring 200 remains parallel to the set inclined surface. This prevents the spring from warping or bending at the end during compression, thus avoiding excessive deformation of the spring 200 and affecting assembly quality. It should also be noted that during the process of the second installation robot 3 removing the protective pressure plate 301, the stop post 23 prevents the end of the spring 200 from being pulled out along with the protective pressure plate 301.

[0055] Optionally, the elastic component assembly equipment also includes a feeding module 4 and an inspection module; the feeding module 4 includes a feeding robot 41 and a feeding tray 42, the inspection module includes a first CCD inspection camera 51 located at the bottom of the movement trajectory of the feeding robot 41, the feeding robot 41 also includes grippers for clamping the fixing plate 100; the feeding robot 41 is also used to place the gripped elastic component into the T-shaped placement slot.

[0056] The loading robot 41 clamps the fixing plate 100 with its grippers, and then the elastic component passes through the first CCD detection camera 51. The first CCD detection camera 51 detects whether the elastic component is a qualified part. If it is a qualified part, the loading robot 41 transfers the elastic component to the T-shaped placement slot.

[0057] Optionally, the flexible component assembly equipment further includes a conveyor belt assembly 61 and a lifting device 62 installed on one side of the bottom of the conveyor belt assembly 61 to lift the workpiece to a set assembly position; the conveyor belt assembly 61 includes a first conveyor belt and a second conveyor belt arranged at intervals, and the lifting device 62 is disposed between the first conveyor belt and the second conveyor belt. Specifically, the conveyor belt assembly 61 conveys a tray carrying the workpiece to a suitable position, and then the lifting device 62 lifts the tray so that the workpiece is at a suitable assembly height.

[0058] Optionally, the flexible component assembly equipment also includes a quality inspection CCD camera 7; the quality inspection CCD camera 7 is located on one side of the bottom of the conveyor belt assembly 61, and the assembly station is set up with the quality inspection CCD camera 7 spaced apart along the conveying direction of the conveyor belt assembly 61. The quality inspection CCD camera 7 is used to inspect the installation quality of the flexible components to prevent unqualified products from flowing into the next process.

[0059] Optionally, the flexible component assembly equipment also includes an NG robot 8 disposed on one side of the quality inspection CCD camera 7; the quality inspection CCD camera 7 and the NG robot 8 are electrically connected, and when the quality inspection CCD camera 7 detects a product that is not installed correctly, the NG robot 8 moves the product to the NG conveyor belt.

[0060] Optionally, the angle between the first groove wall 101 and the horizontal plane is 3°. Optionally, the cross-section of the first groove 11 perpendicular to the extension direction of the first groove 11 is an inverted trapezoid.
