Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to an automation equipment for riveting a spring and a touch piece. Background Art

[0002] With the continuous expansion of the electronics industry and the growing market demand, touch-enabled home appliances are becoming increasingly popular among consumers. During the production process, a touch spring is used to complete the touch function. Compared with traditional mechanical switches and membrane switches, touch springs are a robust alternative and have rapidly and comprehensively replaced traditional solutions.

[0003] However, at present, the existing installation method of touch springs is still basically manual insertion, and the fastest and most convenient placement machine cannot achieve fully automatic riveting and crimping. The only way is to manually insert the touch piece and the spring and then use a riveting machine to press them. The reason is that the spring does not have a crimping piece. Secondly, even if the spring has a crimping piece, the crimping piece of the touch spring has a groove in the middle to press the spring or an irregular surface is formed at the connection between the crimping piece and the connecting clip, which cannot provide a flat or suitable position for the placement machine's suction nozzle to use. Some crimping pieces have notches or uneven sides. Even if they can be sucked, it is relatively troublesome and easy to miss or stick crookedly. It cannot be used at high speed, resulting in very low touch spring assembly efficiency. Summary of the Invention

[0036] Reference Figures 1 to 4 The embodiment of the present invention provides an automated device for riveting a spring 23 and a touch sheet 22, comprising a spring 23 machine 1; a feeding mechanism, which is arranged adjacent to the spring 23 machine 1; a touch sheet 22 fixture, which is arranged at the discharge end of the feeding mechanism, and the feed port of the touch sheet 22 fixture is cooperatively connected with the discharge port of the feeding mechanism; a riveting device, which is arranged above the touch sheet 22 fixture; a transfer robot, which is arranged between the spring 23 machine 1 and the touch sheet 22 fixture; a feeding mechanism, which is arranged adjacent to the touch sheet 22 fixture; and a control cabinet, which is linked to each mechanism for control.

[0037] Among them, the spring 23 machine 1, the touch piece 22 fixture, and the unloading mechanism are arranged within the range of movement of the transfer robot.

[0038] After the spring 23 machine 1 manufactures the spring 23, the transfer robot clamps the spring 23 and transfers it to the touch piece 22 fixture. At the same time, the loading mechanism transports the touch piece 22 to the touch piece 22 fixture. When the touch piece 22 and the spring 23 are in place, the riveting device starts to assemble the touch piece 22 and the spring 23. After the assembly is completed, the transfer robot clamps the workpiece and transfers it to the unloading mechanism. The whole process does not require manual operation and is fully automated. On the one hand, it reduces the labor intensity of workers and improves the production efficiency of the enterprise. On the other hand, it also ensures the assembly quality of the touch spring 23.

[0039] Specifically, as shown in the figure, a raised snap ring 22 - 1 is provided in the middle of the touch sheet 22 , and the snap ring 22 - 1 is used to connect with the snap-fit ​​portion of the spring 23 .

[0040] According to some embodiments of the present application, the fixture for the touch sheet 22 includes a lifting device 4 and a fixing block 5 mounted on the lifting device 4 . The fixing block 5 is provided with a receiving cavity 5 - 1 for placing the touch sheet 22 .

[0041] According to some embodiments of the present application, the lifting device 4 includes a lifting cylinder and a lifting base installed on the driving end of the lifting cylinder, wherein the fixed block 5 is detachably installed on the lifting base, and the lifting device 4 is used to adjust the position of the fixed block 5 to ensure that the position of the touch sheet 22 matches the mounting part of the spring 23 clamped by the transfer robot from the spring 23 machine 1, ensuring that the touch sheet 22 and the spring 23 can be assembled successfully.

[0042] According to some embodiments of the present application, the touch sheet 22 clamp also includes a positioning mechanism, which includes a first cylinder 6 and a paddle 7. The paddle 7 is installed on the driving end of the first cylinder 6, and the end of the paddle 7 is in movable contact with the touch sheet 22 retaining ring 22-1 in the accommodating cavity 5-1.

[0043] According to some embodiments of the present application, the transfer robot includes a second cylinder 8, a mechanical claw 9 installed at the driving end of the second cylinder 8, a translation device 10 installed at the bottom of the second cylinder 8, and a rotation device 11 installed on the translation device 10.

[0044] According to some embodiments of the present application, the translation device 10 includes a translation cylinder and a translation base, wherein the translation base is mounted on the driving end of the translation cylinder, and the second cylinder 8 is mounted on the translation base.

[0045] According to some embodiments of the present application, the rotating device 11 includes a turntable and a rotating motor that drives the turntable. A translation cylinder is fixed to the turntable. Using the rotating device 11 enables the transfer robot to transfer workpieces between various mechanisms, helping to reduce the overall size of the machine and achieve a compact structure. The rotating motor uses a stepper motor to ensure the accuracy of the transfer robot's displacement.

[0046] According to some embodiments of the present application, the loading mechanism includes a vibration screening device 2, a delivery pipe 3 connected to the discharge port of the vibration screening device 2, and a pushing device arranged at the discharge port of the delivery pipe 3.

[0047] According to some embodiments of the present application, the feed pipe 3 is provided with a feed trough 3-1 for conveying the touch sheet 22 and a movable trough 3-2 arranged perpendicular to the feed trough 3-1. The feed trough 3-1 and the movable trough 3-2 are in a "T" design. Specifically, as shown in the figure, the two side edges of the touch sheet 22 are clamped in the feed trough 3-1, and the snap ring 22-1 is located in the movable trough 3-2. In addition, it should be noted that the height of the feed trough 3-1 is higher than the thickness of the edge of the touch sheet 22, but lower than the height of the protrusion of the snap ring 22-1. The purpose is to ensure that when the touch sheet 22 is conveyed to the accommodating cavity 5-1, the opening direction of the snap ring 22-1 is in the same direction as the conveying direction of the mechanical transfer arm from the spring 23 machine 1 to clamp the spring 23, thereby ensuring that the mounting portion of the spring 23 can be smoothly clamped into the snap ring 22-1.

[0048] According to some embodiments of the present application, the pushing device includes a third cylinder 12 and a pushing rod 13 installed at the driving end of the third cylinder 12. A pressing piece 14 is provided at one end of the pushing rod 13. The pressing piece 14 is movably inserted into the movable groove 3-2, and the end of the pressing piece 14 is movably pressed on the touch piece 22 in the feeding groove 3-1.

[0049] According to some embodiments of the present application, the accommodating chamber 5-1 is further provided with a detector for detecting whether a touch pad 22 is placed in the accommodating chamber 5-1, wherein the detector is linked to the pushing device and the control cabinet for control. When the detector detects that a touch pad 22 is placed in the accommodating chamber 5-1, the detector transmits a signal to the control cabinet, which controls the pushing device to pause and push the touch pad 22 in the feeding trough 3-1 into the accommodating chamber 5-1;

[0050] When the detector detects that there is no touch sheet 22 in the accommodating cavity 5-1, the detector transmits a signal to the control cabinet, which controls the pushing device to start and push the touch sheet 22 in the feeding trough 3-1 into the accommodating cavity 5-1.

[0051] The detector of the present application may be an infrared sensor or a pressure sensor.

[0052] According to some embodiments of the present application, the material discharge mechanism includes a first material collection mechanism 15 and a second material collection mechanism 16, each of which includes a material discharge pipe 17 and a material collection box 18. The first material collection mechanism 15 and the second material collection mechanism 16 are respectively used to collect qualified products and unqualified products.

[0053] According to some embodiments of the present application, a detection device 19 is further included for detecting whether the spring 23 and the touch sheet 22 are successfully riveted. The detection device 19 is arranged adjacent to the unloading mechanism, and the transfer robot clamps the riveted workpiece and stays briefly within the monitoring range of the detection device 19.

[0054] It should be noted that the detection device 19 of the present application is a combination of an infrared transmitter and an infrared receiver.

[0055] If the touch sheet 22 is successfully assembled with the spring 23, when the transfer robot briefly places the riveted workpiece within the monitoring range of the detection device 19, the infrared ray emitted by the infrared transmitter is blocked by the touch sheet 22 and cannot be sensed by the infrared receiver, then the workpiece is considered to be qualified. The transfer robot then clamps the workpiece to the inlet of the first collecting mechanism 15.

[0056] If the assembly of the touch piece 22 and the spring 23 is unsuccessful, when the transfer robot briefly stops the riveted workpiece within the monitoring range of the detection device 19, because the assembly of the touch piece 22 and the spring 23 is unsuccessful, the touch piece 22 is not installed on the spring 23, and the infrared transmitter emits infrared rays that directly pass through the spring 23 and are sensed and received by the infrared receiver, it is a substandard product, and the transfer robot clamps it to the feed port of the second collection mechanism 16.

[0057] According to some embodiments of the present application, the riveting device includes a pressing drive 20 and a riveting rod 21 installed on the pressing drive 20 . The riveting rod 21 presses the touch sheet 22 onto the spring 23 under the drive of the pressing drive 20 .

[0058] The riveting rod 21 and the downward driving 20 of the present application are detachably mounted, so that the user can replace the riveting rod 21 according to the diameter of the spring 23 .
