[0022] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figures 1 to 6 As shown, A flat washer and nut assembly machine, comprising a slideway group 1, a bracket 2 and a material supply part 3, the slideway group 1 comprising a flat washer slideway 11 and a nut slideway 12, an assembly port 13 is provided at the output end of the slideway group 1, each slideway is provided with a stopper 14 adapted to the corresponding assembly part, the nut and flat washer assembly holes abutting against the stopper 14 in each slideway correspond to and face the assembly port 13, a first power device 5 is provided on the bracket 2, a driving wheel 51 is provided on the output shaft of the first power device 5, and the first power device 5 is provided with a drive wheel 51 through The wire is connected to the power supply to drive the driving wheel 51 to rotate. The driving wheel 51 can be made of rubber, silicone, polyurethane and other materials, and has the characteristics of elasticity and wear resistance. The driving wheel 51 and the nut are driven by friction. In the case of bad teeth or mismatch of the screw or nut, the driving wheel 51 and the nut will slip, and the nut will not be driven to rotate. Therefore, there will be no accident of hand injury caused by the rotation of the screw. The speed of the first power device 5 is 500r / min to 6000r / min, preferably 2000 rpm; The slideway assembly 1 is tilted and mounted on the bracket 2. The angle between the slideway assembly 1 and the horizontal plane is called the tilt angle. The tilt angle is between 15° and 30°, and preferably 23.5°. When the tilt angle of the slideway assembly 1 is less than 18°, the nut is not easy to slide in the slideway under its own gravity. When the tilt angle of the slideway assembly 1 is greater than 28°, the nut and other assembly parts slide faster and are easy to rush out of the slideway. The slideway assembly 1 is composed of two or more slideways arranged side by side. The front end of the slideway assembly 1 is fixed to the bracket 1 with two fasteners. This embodiment provides a setting scheme for two slideways. The material supply part 3 includes a base 31, a rotating disk 32 and a second power device 33. A material bin 34 is provided on the base 31. The output shaft of the second power device 33 is connected to the rotating disk 32. Two flange couplings are fixed on the output shaft of the second power device. The two flange couplings are symmetrically arranged on the upper and lower surfaces of the rotating disk. Corresponding connecting holes are provided on the rotating disk and the flange coupling, and the rotating disk is fixed between the two flange couplings by fasteners to ensure the firmness of the connection. A radial threaded hole is provided on the flange coupling, and the top screw is screwed in the radial threaded hole to support the output shaft of the second power device.

The front and rear sides of the rotating disk 32 are respectively provided with a flat gasket conveying part 37 and a nut bin 36. The rear end of the flat washer slideway 11 of the mother conveying part 38 is provided with a flat washer guide bar 15 to guide the flat washer of the flat washer conveying part 37 to enter the flat washer slideway 11, and the rear end of the nut slideway 12 is provided with a nut guide bar 16 to guide the nut of the nut conveying part 38 to enter the nut slideway 12. The second power device 33 is a reduction motor, which is connected to the power supply through a wire and is provided with a switch. The switch can be a foot switch to facilitate the control of the rotation of the reduction motor. At the same time, a speed regulating device is provided to control the speed of the reduction motor so that its feeding speed meets the assembly requirements, or the second power device 33 is connected to the circuit board through a wire, and the circuit board can control the forward and reverse rotation of the second power device 33 and control the second power device 33 to automatically reverse and then rotate forward in the event of a jam, so that the jammed nut or gasket changes position and the machine runs smoothly; Material preparation: Start the second power device 33, which drives the rotating disk 32 to rotate. The rotating disk 32 separates the material bin 34 into a flat pad bin 35 and a nut bin 36, so that the flat pads and nuts are stored in the corresponding bins respectively. The flat pad conveying part 37 and the nut conveying part 38 start to work during the rotation of the rotating disk 32. Material conveying: The pushing structure of the flat pad conveying part 37 pushes the flat pad to the flat pad guide bar 15, and the flat pad enters the flat pad slideway 11 along the flat pad guide bar 15; the nut conveying part 38 uses the same method to send the nut into the nut slideway 12 through the nut guide bar 16. Positioning: The flat pad and the nut slide down in their respective slideways by gravity and the inclination of the slideways, and stop when they reach the stopper 14 in the slideway. At this time, the assembly holes of the flat pad and the nut correspond to each other and are facing the assembly port 13, completing the positioning before assembly. Assembly: Start the first power device 5, and the driving wheel 51 rotates to provide a certain power for the assembly operation or trigger the assembly action. At the installation opening 13, the screw is manually held to align the positioned flat washer and nut for assembly. The screw passes through the assembly hole of the flat washer and enters the screw hole of the nut, pushing the nut to slide along the rear side wall of the slideway and contact the driving wheel. The driving wheel drives the nut to rotate and screw together with the screw to realize the assembly of the nut and the screw. The degree of automation is high: from material storage, transportation to positioning, the entire process is basically automated, reducing manual intervention, improving production efficiency, and reducing labor costs. The positioning is precise: the stop portion 14 ensures that the flat washer and the nut are accurately positioned at the assembly opening 13, so that the assembly holes correspond accurately, ensuring the assembly quality and reducing the defective rate. The structure is compact and reasonable: the layout of each component is compact, and the space utilization rate is high, which is convenient for installation and use in different production sites.

It has strong versatility: the dimensions of components such as slideways and guide bars can be adjusted to adapt to the assembly of flat washers and nuts of different specifications, and it has good versatility and flexibility.
[0023] In the embodiment, the flat washer conveying portion 37 includes a flat washer pushing protrusion 4 and a flat washer supporting plate 41, the flat washer supporting plate 41 is fixed to the front side of the rotating disk 32, and the flat washer pushing protrusion 4 is evenly distributed on the front side of the rotating disk 32. The nut conveying portion 38 includes a nut pushing protrusion 42 and a nut supporting plate 43, the nut supporting plate 43 is fixed to the rear side of the rotating disk 32, and the nut pushing protrusion 42 is evenly distributed on the rear side of the rotating disk 32. In the flat washer conveying portion 37, when the second power device 33 drives the rotating disk 32 During the rotation, the flat pad support plate 41 fixed to the front side of the rotating disk 32 rotates accordingly, and the flat pad pushing protrusions 4 evenly distributed on the front side of the rotating disk 32 use the circular motion generated by the rotation to push the flat pads in the flat pad bin 35 forward one by one. Under the continuous push of the flat pad pushing protrusions 4, the flat pads are attached to the front side of the rotating disk 32 under the action of the flat pad pushing protrusions 4 and the flat pad support plate 41, and rotate together with the rotating disk 32, and under the guidance of the flat pad guide strips 15, slide into the flat pad slideway 11 along the channel groove; The principle of the nut conveying part 38 is similar to that of the nut conveying part 38. The nut supporting plate 43 fixed on the rear side of the rotating disk 32 rotates with the rotating disk 32. The nut pushing protrusions 42 evenly distributed on the rear side of the rotating disk 32 continuously push the nuts in the nut bin 36. The nuts are guided by the nut guide strips 16 and finally enter the nut slideway 12. Efficient conveying: Through the rotation of the rotating disk 32, the flat washer pushing convex body 4 and the nut pushing convex body 42 can continuously push the flat washer and the nut, which greatly improves the material conveying efficiency and meets the needs of rapid assembly; Good stability: the flat washer support plate 41 and the nut support plate 43 provide a stable support platform for the conveying of the flat washer and the nut, respectively, to reduce shaking and deviation during the conveying process, and ensure that the flat washer and the nut can accurately enter the corresponding guide bar and slideway; Reasonable layout: the flat washer conveying part 37 and the nut conveying part 38 are respectively arranged on the front and rear sides of the rotating disk 32, making full use of the space, making the overall structure compact, and the various components work together without interfering with each other; Strong adaptability: the flat washers push the convex bodies 4 and the nut pushes the convex bodies 42 to be evenly distributed, which can adapt to different numbers and arrangements of flat washers and nuts, and can better complete the conveying task regardless of the production needs of small quantities and diversity or large quantities and singleness.
[0024] In the embodiment, the flat washer guide bar 15 overlaps the front end surface of the rotating disk 32, and a channel groove 17 adapted to the flat washer pushing protrusion 4 is provided on the flat washer guide bar 15; the nut guide bar 16 overlaps the rear end surface of the rotating disk 32, and the nut guide bar 16 is provided with a channel groove 17 adapted to the nut pushing protrusion 42, so as to better guide the flat washer and the nut into their respective slideways. At the same time, the channel grooves of each guide bar allow the corresponding pushing protrusion to pass through, which will not affect the normal rotation of the rotating disk 32.
[0025] In the embodiment, the flat washer guide bar 15 is provided with a flat washer discharge bevel 18, and the nut guide bar 16 is provided with a nut discharge bevel 19, which can not only allow excess flat washers or nuts to slide from the discharge bevel into the silo, but also automatically discharge materials that do not meet the requirements. For example, a flat washer with burrs, when fitted with the rotating disk, will have a gap larger than the gap between a normal flat washer and the rotating disk, so it is easy to slide down at the discharge bevel, which plays a screening role, ensures the quality of the flat washers and nuts entering the assembly link, helps to improve the qualified rate of assembled products, and avoids flat washers with burrs from being stuck in the slide.
[0026] In the embodiment, material shifting rods 44 are evenly distributed on both sides of the rotating disk 32, one end of the material shifting rod 44 is fixed on the connecting ring and the other end is installed in the connecting holes on the flat washer support plate 41 and the nut support plate 43. The material shifting rod 44 can effectively shift the flat washers and nuts in the flat washer bin 35 and the nut bin 36 to make the material distribution more even and avoid accumulation, thereby ensuring that the flat washer pushing protrusion 4 and the nut pushing protrusion 42 can push the material smoothly, thereby improving the smoothness and stability of material transportation.
[0027] In the embodiment, the slide group 1 includes a front side plate 61, a flat pad bottom plate 62, a middle partition plate 63, a nut bottom plate 64 and a rear side plate 65 which are arranged in sequence from front to back. The flat pad bottom plate 62 and the nut bottom plate 64 can be composed of multiple bottom plates, and a bottom plate partition can be added to the rear end to increase the width, so that the flat pad and the nut can enter the slide groove more easily. A flat pad conveying chute 66 is formed between the front side plate 61 and the middle partition plate 63, and a nut conveying chute 67 is formed between the middle partition plate 63 and the rear side plate 65. This modular structure of the slide group makes each component relatively independent, which is convenient for inspection, maintenance and replacement of a single component. If it is necessary to adapt to flat pads and nuts of different specifications, it can also be achieved by adjusting or replacing the corresponding side plates, bottom plates and other components, thereby reducing the maintenance cost and adjustment difficulty of the equipment. The structural design of the slide group makes full use of the space, integrates the conveying channels of the flat pads and nuts, and realizes efficient conveying of the two materials in a limited space, making the structure of the entire assembly machine more compact, saving the equipment's footprint, and suitable for different production sites and environments.
[0028] In the embodiment, a positioning plate 68 is formed at the rear end of the middle partition 63, and a positioning protrusion 69 is provided on the positioning plate 68, and a groove 45 adapted to the positioning protrusion 69 is provided on the enclosure 39 of the base 31.

The setting of the positioning plate 68 and the positioning protrusion 69 not only plays a positioning role, but also enhances the connection strength between the slide group 1 and the base 31 to a certain extent, so that the structure of the entire assembly machine is more stable, can withstand a larger workload, and adapt to different production environments and work requirements.
[0029] In the embodiment, the nut support plate 43 includes a support ring 46 and a cover plate 47. The support ring 46 is fixed between the cover plate 47 and the rear side of the rotating disk 32, thereby reducing the overall weight and material and lowering the manufacturing cost.
[0030] In the embodiment, the base 31 also includes a base frame 48 and a connecting frame 49. The base frame 48 is arranged below the enclosure 39, and the connecting frame 49 is fixed to the side of the enclosure 39. The connecting frame 49 is fixed by welding or screws.

The material plates 7 include a material holding plate 71 and a guide plate 72. Bending edges are provided on both sides of the material holding plate 71 to block the gasket and the nut. The gap between the guide plate 72 and the rotating disk 32 forms an orientation zone 73. The nut and the flat gasket slide into the orientation zone 73 and are vertically distributed. The design of the material holding plate 71, the guide plate 72 and the orientation zone 73 of the material plate 7 enables the flat gasket and the nut to be vertically distributed before entering the conveying process, thereby realizing accurate orientation of the material. This is conducive to the flat gasket pushing the protrusion 4 and the nut pushing the protrusion 42 to accurately contact and push the flat gasket and the nut, thereby improving the accuracy and stability of material conveying and reducing conveying failures caused by incorrect material posture. Improved conveying efficiency: The directional area 73 allows the flat washers and nuts to enter the conveying process in a suitable posture, avoiding jamming and confusion of the materials during the conveying process, making the entire conveying process smoother, thereby improving the conveying efficiency of the flat washers and nuts, and further improving the overall working efficiency of the assembly machine; Enhanced equipment adaptability: This design can adapt to flat washers and nuts of different specifications. By adjusting parameters such as the gap between the guide plate 72 and the rotating disk 32, it can meet the directional requirements of materials of different sizes, thereby enhancing the adaptability and versatility of the equipment to different materials; Compact and reasonable structure: The setting of the material plate 7 cleverly utilizes the space on both sides of the enclosure 39 and cooperates with other components to make the structure of the entire assembly machine more compact, realizing the functions of receiving and orienting materials in a limited space, which not only saves space but also ensures the normal operation of the equipment, making it convenient for the equipment to be installed and used in different production sites.

Turn on the power switch of the second power device 33 (if it is a foot switch, you can start it by lightly stepping on the foot switch). The second power device 33 is a reduction motor, which starts to drive the rotating disk 32 to rotate slowly. According to the actual assembly requirements, the speed of the second power device 33 is adjusted by the speed regulating device. If the material conveying speed is too fast or too slow, the speed can be appropriately increased or decreased to match the feeding speed of the flat washers and nuts with the subsequent assembly rhythm. Material conveying and orientation Flat pad conveying: During the rotation of the rotating disk 32, the flat pad supporting plate 41 rotates accordingly, and the flat pad pushing protrusions 4 evenly distributed on the front side of the rotating disk 32 use circular motion to push the flat pads in the flat pad bin 35 forward one by one. Under the action of the flat pad pushing protrusions 4 and the flat pad supporting plate 41, the flat pads move in line with the front side of the rotating disk 32. When the flat pads reach the flat pad guide strips 15, since the channel grooves 17 are adapted to the flat pad pushing protrusions 4, the flat pads slide into the flat pad slideway 11 along the channel grooves. If there are any redundant or non-compliant flat pads (such as those with burrs) due to the abnormal gap between them and the rotating disk, they will slide back to the material bin or the designated collection area through the flat pad discharging bevel 18. Nut conveying: Similarly, on the rear side of the rotating disk 32, the nut support plate 43 rotates with the disk, and the nut pushes the convex body 42 to continuously push the nuts in the nut bin 36 backward to the nut guide bar 16. The nuts enter the nut slideway 12 under the guidance of the channel groove 17 of the nut guide bar 16, and the abnormal nuts are discharged through the nut discharge bevel 19. In this process, the material removal rods 44 on both sides of the rotating disk 32 continuously move the flat pads and nuts to prevent the materials from accumulating in the flat pad bin 35 and the nut bin 36, so as to ensure smooth conveying. Material orientation: The flat washers and nuts that slide down from the periphery of the rotating disk 32 first fall onto the material receiving plates 71 of the material plates 7 on both sides of the enclosure 39. Under the action of gravity, the materials slide along the material receiving plates 71 to the guide plates 72. The gap between the guide plates 72 and the rotating disk 32 forms an orientation zone 73. After the flat washers and nuts slide into the orientation zone 73, they are vertically distributed due to space limitations and their own shapes, so as to be accurately pushed to the slideway in preparation for the subsequent release. Material positioning and assembly preparation The flat washer and the nut slide down in their respective slideways by gravity and the inclination of the slideway assembly 1, and stop when they reach the stopper 14 in the slideway. At this time, the assembly holes of the flat washer and the nut correspond to each other and face the assembly opening 13, completing the positioning before assembly. At the same time, the adsorption magnets 81 of the flat washer bottom plate 62 and the nut bottom plate 64 located at the stopper 14 will use magnetic force to adsorb the flat washer and the nut, making them more stable in the positioning position and less likely to move. The power switch of the first power device 5 is turned on, the first power device 5 starts to work, and the driving wheel 51 on its output shaft starts to rotate. If the speed of the first power device 5 is not set in advance, it can be adjusted within the range of 500r / min to 6000r / min according to the actual assembly situation, and 2000 rpm is usually preferred. The operator holds the screw rod and aligns one end of the screw rod with the flat washer and nut positioned at the assembly opening 13, so that the screw rod passes through the assembly hole of the flat washer and presses into the screw hole of the nut. Then, the operator gently pushes the nut to slide along the rear side wall of the slideway and contact the driving wheel 51. The driving wheel 51 is made of elastic and wear-resistant materials such as rubber, silicone, and polyurethane. It drives the nut to rotate through friction transmission with the nut to realize the screw connection assembly of the nut and the screw rod. During the assembly process, if the screw or nut has broken teeth or is not compatible, the driving wheel 51 and the nut will slip to avoid accidental injury caused by the rotation of the screw.
