Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, in particular to an electrical accessories screw assembly machine. Background Art

[0002] In the mechanical field, screws as fasteners are usually used together with washers, and the screws are usually passed through the washers manually. When there is a huge demand for screws with washers in a short period of time, the manual assembly method becomes extremely inefficient and often cannot meet the needs of efficient manufacturing applications.

[0003] Existing electrical accessory screws usually need to be assembled with a number of gasket components before they can be put into use. However, such assembled screws usually need to be installed at multiple angles, and the assembled screws are also more three-dimensional. Relying solely on existing mechanical grippers and other components has extremely low work efficiency and cannot perform continuous and systematic work. Therefore, a device specifically for assembling electrical accessory screws is needed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the present invention to solve the technical problems is: an electrical accessories screw assembly machine, comprising a container, a copper sheet storage box is arranged on the back of the container, a gasket transfer component is arranged on the front of the container, and a screw transfer component is arranged on the right side of the container; a copper sheet feeding component is arranged at the front end of the copper sheet storage box, a screw reversing component is arranged at the front of the gasket transfer component, and a spiral screwing component is arranged at the front end of the copper sheet feeding component.

[0005] Furthermore, the gasket transfer component includes a feeding box shell, a gasket circular vibrator is fixedly connected to the discharge port of the feeding box shell, a vibration base is arranged at the bottom of the gasket circular vibrator, a long guide rail is fixedly connected to the end of the gasket circular vibrator close to the container, a gasket straight vibrator is fixedly connected to the lower surface of the long guide rail, the gasket is a metal sheet sleeved on the top of the screw, and the gasket circular vibrator can be vibrated by the gasket straight vibrator at the bottom, so as to transport the gasket along the long guide rail to the interior of the container.

[0006] Furthermore, the screw transfer component includes a screw translation upper and lower cylinder, the outer surface of the screw translation upper and lower cylinder is fixedly connected to the inner wall of the container, the front end of the screw translation upper and lower cylinder is fixedly connected to a screw feeding cylinder, the bottom end of the screw feeding cylinder is provided with a screw machine, and the left side of the screw translation upper and lower cylinder is provided with a screw gasket guide component. After the screw machine discharges the screws inside, the screw feeding cylinder absorbs the top of the screw, and the screw is pulled out from the inside of the screw machine through the screw translation upper and lower cylinder, and then the transfer work is performed.

[0007] Furthermore, the screw gasket guide component includes a screw vacuum suction plate, the screw taking cylinder will place the taken screw on the screw vacuum suction plate, and fix the screw in a vertical state by vacuum adsorption. The left end of the screw vacuum suction plate is fixedly connected with a combination socket, and the outer surface of the combination socket is fixedly connected with a transfer straight rail. The end of the long guide slide rail away from the gasket circular vibration is fixedly connected to the inner wall of the transfer straight rail through the combination socket, and the top of the transfer straight rail is provided with a screw moving cylinder. The end of the transfer straight rail away from the combination socket is slidably connected with a screw assembly translation cylinder, and the bottom end of the screw assembly translation cylinder is clamped with a combination screw. The inner wall of the transfer straight rail is slidably connected with a transport transmission belt, and the lower surface of the transfer straight rail is fixedly connected to the bottom of the inner wall of the container. After the gasket reaches the predetermined combination socket first, the screw moving cylinder will remove the screw from the screw vacuum suction plate, insert it into the gasket of the combination socket, and transfer it from right to left along the transfer straight rail through the transport transmission belt.

[0008] Furthermore, the copper sheet storage box includes a copper sheet straight vibrator, and the top of the copper sheet straight vibrator is fixedly connected to a right-angle guide rail. Since the shape of the copper sheet is a small bent plate, and the bending angle is approximately a right angle, in order to enable the copper sheet to slide stably along the inner wall of the right-angle guide rail, a right-angle groove matched with the copper sheet is provided on the inner wall of the right-angle guide rail, and the end of the right-angle guide rail away from the copper sheet straight vibrator is slidably connected to a transfer slide, and the end of the right-angle guide slide away from the transfer slide is connected to the copper sheet storage box. The inner cavity is fixedly connected, and the front end of the transfer slide is fixedly connected to a copper sheet material dividing cylinder. The transfer slide can slide in the direction perpendicular to the right-angle guide rail under the traction of the copper sheet material dividing cylinder, and a right-angle groove adapted to the copper sheet is also opened at the end of the transfer slide away from the copper sheet material dividing cylinder, which is used to catch the copper sheet sliding along the right-angle guide rail. The back of the transfer slide is fixedly connected to a copper sheet pushing cylinder through a guide slide frame, and the copper sheet pushing cylinder can push the copper sheet inside the transfer slide to the spiral screwing component.

[0009] Furthermore, the spiral screwing component includes a circumferential turntable, the axis of the circumferential turntable is fixedly connected with a screw to tighten the upper and lower cylinders, the upper part of the outer surface of the screw to tighten the upper and lower cylinders is fixedly connected with a tightening shaft, the bottom end of the tightening shaft is fixedly connected with a screwdriver, and the bottom end of the screw to tighten the upper and lower cylinders is fixedly connected to the bottom of the inner wall of the container.

[0010] Furthermore, screw unloading and clamping cylinders are evenly arranged on the upper surface of the circular turntable, and clamping grooves are provided on the upper surfaces of the screw unloading and clamping cylinders. The number of the screw unloading and clamping cylinders is eight, and the lower surfaces of the screw unloading and clamping cylinders are fixedly connected to the upper surface of the circular turntable. A product unloading plate is fixedly connected to one side of the outer surface of the container close to the circular turntable through an opening. Inside the screw unloading and clamping cylinders, screws with gaskets and copper sheets are combined together through clamping grooves, and then combined together by rotating the screws with a screwdriver.

[0011] Furthermore, the screw reversal component includes upper and lower screw loosening cylinders, the upper part of the outer surface of the upper and lower screw loosening cylinders is fixedly connected with a loosening shaft, the bottom end of the loosening shaft is fixedly connected with a screw loosening claw, and the bottom end of the upper and lower screw loosening cylinders is fixedly connected to the bottom of the inner wall of the container. The function of the screw reversal component is to reverse and loosen the over-tightened screws to avoid excessive tightening of the assembly.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When using the device to assemble screws for electrical accessories, the screws and washers are assembled and transferred first, and then assembled with the copper sheet with a more complex structure, so as to avoid the problem that the screws are difficult to align with the washers and copper sheets at the same time when the three are assembled simultaneously, thereby reducing the precision requirements for the assembled parts and making the assembly work more logical and sequential, avoiding problems such as missing installation and empty installation, and greatly improving assembly efficiency, increasing output, and increasing economic benefits.

[0014] 2. Before the screws are inserted into the combination sockets and assembled with the gaskets, the screws will be placed on the screw vacuum suction plate for shutdown to ensure that the gaskets are installed in the combination sockets first, and then the screws on the screw vacuum suction plate are inserted into the combination sockets to ensure docking. While the screws are temporarily on the screw vacuum suction plate, the screw vacuum suction plate will correct the position of the screws and remove impurities in the screw threads through the adsorption function, thereby ensuring the cleanliness of each screw and making the assembled accessory screws cleaner.

[0015] 3. The copper sheets are transported through a special right-angle guide rail. Since the inner wall of the right-angle guide rail is provided with a right-angle groove complementary to the copper sheets, although the copper sheets are transported by sliding on the shaking right-angle guide rail, they will not slide out from the inner wall of the right-angle guide rail due to the restriction of the right-angle groove, thus avoiding the problem of the copper sheets falling off when sliding. When the sliding transfer slide is being transported, one side of the interface can block the end of the right-angle guide rail, so that the copper sheets are temporarily retained inside the right-angle guide rail, thereby preventing the problem of the copper sheets inside the right-angle guide rail being transported too fast, exceeding the transport capacity of the transfer slide and thus jamming the copper sheet feeding components.

[0016] 4. In the process of transferring the accessory screws to the blanking plate, they will pass through the screw reversing component. At this time, the screw reversing component will scan the accessory screws inside the screw blanking and clamping cylinder, and reversely rotate the over-tightened screws by loosening the screw clamps to release the over-tightened state of the accessory screws, ensuring that the copper sheet of each accessory screw will not be easily broken due to excessive screw tightening, thereby eliminating the hidden dangers caused by system processing.

[0033] The copper sheet storage box 3 includes a copper sheet straight vibrator 61, and a right-angle guide rail 62 is fixedly connected to the top of the copper sheet straight vibrator 61. Since the shape of the copper sheet 66 is a small bent plate, and the bending angle is approximately a right angle, in order to enable the copper sheet 66 to stably slide along the inner wall of the right-angle guide rail 62, a right-angle groove adapted to the copper sheet 66 is provided on the inner wall of the right-angle guide rail 62, and one end of the right-angle guide rail 62 away from the copper sheet straight vibrator 61 is slidably connected to a transfer slide 63, and one end of the right-angle guide rail 62 away from the transfer slide 63 is fixedly connected to the inner cavity of the copper sheet storage box 3. Next, the front end of the transfer slide 63 is fixedly connected to the copper sheet dividing cylinder 64. The transfer slide 63 can slide in the direction perpendicular to the right-angle guide rail 62 under the traction of the copper sheet dividing cylinder 64, and a right-angle groove adapted to the copper sheet 66 is also opened at the end of the transfer slide 63 away from the copper sheet dividing cylinder 64, which is used to receive the copper sheet 66 sliding along the right-angle guide rail 62. The back of the transfer slide 63 is fixedly connected to the copper sheet pushing cylinder 65 through the guide slide frame. The copper sheet pushing cylinder 65 can push the copper sheet 66 inside the transfer slide 63 to the spiral screwing component 7.

[0034] The spiral screwing component 7 includes a circumferential turntable 71, and a screw-tightening upper and lower cylinders 72 are fixedly connected at the axis of the circumferential turntable 71. A tightening shaft 73 is fixedly connected to the upper part of the outer surface of the screw-tightening upper and lower cylinders 72. A screwdriver 74 is fixedly connected to the bottom end of the tightening shaft 73. The bottom end of the screw-tightening upper and lower cylinders 72 is fixedly connected to the bottom of the inner wall of the container 1.

[0035] The upper surface of the circular turntable 71 is evenly provided with screw unloading and clamping cylinders 75, and the upper surface of the screw unloading and clamping cylinders 75 is provided with clamping grooves 76. The number of screw unloading and clamping cylinders 75 is eight, and the lower surface of the screw unloading and clamping cylinders 75 is fixedly connected to the upper surface of the circular turntable 71. A product unloading plate 77 is fixedly connected to the side of the outer surface of the container 1 close to the circular turntable 71 through an opening. Inside the screw unloading and clamping cylinder 75, the screw with a gasket and the copper sheet 66 are combined together through the clamping groove 76, and then they are combined together by rotating the screw with a screwdriver 74.

[0036] The screw reversing component 5 includes a screw loosening upper and lower cylinders 51, the upper part of the outer surface of the screw loosening upper and lower cylinders 51 is fixedly connected with a loosening shaft 52, the bottom end of the loosening shaft 52 is fixedly connected with a screw loosening clamp 53, the bottom end of the screw loosening upper and lower cylinders 51 is fixedly connected to the bottom of the inner wall of the container 1, and the function of the screw reversing component 5 is to reverse and loosen the screws that are screwed too tight to avoid excessive tightening of the assembly.

[0037] When using the device to assemble screws for electrical accessories, first start the vibration base 23 and the gasket straight vibrator 25 of the gasket transfer component 2, and make the gasket inside the gasket circular vibrator 22 slide along the long guide rail 24 to the combined socket 432 by vibrating. In this process, the screw machine 44 also discharges the screws, and the screw picking cylinder 42 temporarily clamps the screws to the screw vacuum suction plate 433 for fixation, waiting for use.

[0038] When the gasket reaches the combination socket 432, the screw moving cylinder 434 inserts the screw at the screw vacuum suction plate 433 into the combination socket 432, so that the screw and the gasket are screwed together, and then the screw is loosened, and the transportation work is carried out from right to left along the transfer straight rail 431 under the control of the transportation transmission belt 435, and then the combination screw 437 reaches the predetermined position at the end of the transfer straight rail 431, that is, Figure 7 After reaching the position shown, the end is clamped by the screw assembly translation cylinder 436 and is ready to be transferred to the spiral screwing component 7.

[0039] When the copper sheet feeding component 6 is working, the right-angle copper sheet 66 located inside the copper sheet storage box 3 will slide and transport along the inner wall of the right-angle guide slide rail 62, and the copper sheet straight vibrator 61 will vibrate the right-angle guide slide rail 62 to accelerate the sliding of the copper sheet 66. At this time, the transfer slide plate 63 is pulled by the copper sheet dividing cylinder 64, and its docking interface is directly opposite to the end position of the right-angle guide slide rail 62. When the copper sheet 66 detaches from the right-angle guide slide rail 62 and enters the transfer slide plate 63, the copper sheet dividing cylinder 64 will push the transfer slide plate 63 to slide toward the side of the copper sheet pushing cylinder 65.

[0040] The circular turntable 71 will rotate clockwise under the control of the bottom shaft of the upper and lower cylinders 72 for tightening the screws, so after the combination screw 437 is installed on the clamping groove 76, it will automatically combine with the copper sheet 66 installed in advance. At this time, the screw unloading and clamping cylinder 75 clamps the copper sheet 66 and the combination screw 437 by pressurizing, and then screws the screwdriver 74 to tighten the screws to complete the assembly of the accessory screws.

[0041] During the process of transferring the accessory screw to the position facing the blanking plate 77, it will pass through the screw reversing component 5. At this time, the screw reversing component 5 will scan the accessory screw inside the screw blanking and clamping cylinder 75, and reversely rotate the over-tightened screw by loosening the screw clamping jaw 53 to release the over-tightened state of the accessory screw. After the tightening is completed, the accessory screw is transferred to the position facing the blanking plate 77. At this time, the screw blanking and clamping cylinder 75 decompresses and loosens its clamping groove 76, and the accessory screw slides out along the blanking plate 77 to obtain the assembled electrical accessory screw.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
