Embodiment

[0054] The present invention will be further described in detail below with reference to the accompanying drawings.

[0055] This specific embodiment is only an interpretation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law. Example

[0056] An automatic screw and gasket batching method, referring to Figures 1 to 14 , based on a screw and gasket batching system, the screw and gasket batching system includes a batching box 5, a control system, and a screw batching mechanism 2, a first barcode scanner 6, a gasket batching mechanism 3, and a second barcode scanner respectively connected to the control system; the screw and gasket batching system further includes a loading mechanism 1 and an unloading mechanism 4; specifically, in this embodiment, the first barcode scanner 6 is installed on the screw batching mechanism 2, and the second barcode scanner is installed on the gasket batching mechanism 3. Among them, the method includes the following processes, namely customizing the batching box, screw batching, and gasket batching.

[0057] Referring to Figures 1 to 3, The customized ingredient box process specifically includes: forming a screw formula for the specifications and quantities of the screws required for the assembly components, forming a gasket formula for the specifications and quantities of the gaskets that match the screws, processing the corresponding ingredient plate 51 according to the screw formula, and placing the ingredient plate 51 in the ingredient box 5; entering the screw formula and the gasket formula into the control system, then associating the screw formula and the gasket formula to an identification code in the control system, and setting this identification code 55 on the corresponding ingredient box; in this embodiment, the control system includes a PLC controller and a human-machine interaction device; entering the screw formula and the gasket formula into the human-machine interaction device, and then associating the screw formula and the gasket formula to an identification code in the human-machine interaction device; specifically, a new identification code can be generated using coding generation software in the human-machine interaction device, then the screw formula and the gasket formula are associated with this new identification code, and then this identification code is set on the ingredient box 5 by means of printing and pasting, printing, or laser, etc., preferably on the outer side wall of the ingredient box 5; of course, the screw formula and the gasket formula can also be associated with an identification code that has already been set on the ingredient box 5, and no limitation is made here; that is to say, the association between the screw formula and the gasket formula and the identification code can be changed to facilitate actual operation; among them, the identification code can be a barcode or a two-dimensional code, etc.

[0058] Therefore, in this embodiment, the ingredient box is customized according to different assembly components, realizing the one-to-one association of the assembly components, the screw formula, the gasket formula, the identification code, the ingredient box, and the ingredient plate. This can not only effectively avoid the problem of incorrect ingredient preparation, but also facilitate the automated ingredient preparation of screws and gaskets.

[0059] Refer to Figure 2 and Figure 3 , Specifically, in this embodiment, a plurality of screw positioning holes 511 corresponding to the screw formula are opened on the ingredient plate 51, and a magnetic plate 52 located below the ingredient plate 51 is also provided in the ingredient box 5; for example, if the screw formula is 10 M5 screws and 20 M6 screws, then 10 screw positioning holes 511 that match the screw heads of the M5 screws and 20 screw positioning holes 511 that match the screw heads of the M6 screws are opened on the ingredient plate 51; placing the screws vertically with the screw heads facing down in the screw positioning holes 511 is beneficial to improving the stability of the screws and facilitating the sleeving of gaskets on the screws.

[0060] Refer to Figure 2 and Figure 3, in addition, placing the screw head downward in the screw positioning hole 511 and cooperating with the magnetic attraction of the magnetic plate 52 to the screw can effectively improve the stability of the screw, prevent the screw from tipping over during placement or during the turnover of the ingredient box, and also prevent the screw from shifting, thereby improving the stability of the system operation; in this embodiment, the screw positioning hole 511 penetrates the ingredient plate 51, so that the screw is in direct contact with the magnetic plate 52, which can improve the stability of the screw; using one magnetic plate 52 can reduce the number of parts and is convenient for assembly; preferably, a partition is provided below the magnetic plate 52 to increase the distance between the magnetic plate 52 and the bottom wall of the ingredient box 5, thereby reducing the magnetic attraction of the magnetic plate 52 to the area below it; after ingredient preparation, in order to facilitate the handling of the ingredient box 5, the ingredient boxes 5 will be stacked. To avoid the magnetic attraction of the magnetic plate 52 in the upper ingredient box 5 affecting the screws in the lower ingredient box 5, it is necessary to reduce the magnetic attraction of the magnetic plate 52 to the area below it; in this embodiment, a partition is provided below the magnetic plate 52 to increase the distance between the magnetic plate 52 and the bottom wall of the ingredient box 5, which can reduce the magnetic attraction of the magnetic plate to the area below it, and the structure is simple and the production cost is low.

[0061] Refer to Figure 2 and Figure 3 , in this embodiment, a first partition 53 and a second partition 54 are sequentially provided below the magnetic plate 52. The first partition 53 is a rigid plate, and the second partition 54 is a flexible plate. Specifically, the first partition 53 is a PP plate (polypropylene plate), and the second partition 54 is a foam board; in this embodiment, the second partition 54 is in contact with the inner bottom wall of the ingredient box 5 and can also play a buffering role; the foam is easy to deform, and the magnetic plate 52 is relatively soft, so a rigid plate is used as the first partition 53 between the magnetic plate 52 and the second partition 54, which can also play a role of fixing and supporting, and is beneficial to ensuring the position accuracy of the screw positioning hole 511; therefore, in this embodiment, the first partition 53 and the second partition 54 cooperate, not only playing the role of reducing the magnetic attraction of the magnetic plate 52 to the area below it, but also playing the roles of fixing and supporting and buffering respectively; the thicknesses of the first partition 53 and the second partition 54 can be adjusted as needed and are not limited here; of course, in other alternative embodiments, the number of layers and materials of the partition can be adjusted as needed, or the influence caused by magnetic attraction during stacking can be avoided by adjusting the height of the ingredient box 5, which is not limited here.

[0062] Refer to Figure 2 and Figure 3, in this embodiment, adhesive layers are respectively provided between the batching plate 51 and the magnetic plate 52, between the magnetic plate 52 and the first partition plate 53, between the first partition plate 53 and the second partition plate 54, and between the second partition plate 54 and the batching box 5; specifically, in this embodiment, each plate is connected by double-sided tape, and the plate and the batching box are also connected by double-sided tape, so that each plate is fixed relative to the batching box; Using the adhesive layer to achieve connection has the advantages of convenient assembly and low cost, and is also convenient for disassembly.

[0063] Refer to Figure 2 and Figure 3 , specifically, in this embodiment, a gasket (not shown in the drawings) for visual recognition and positioning is fixedly provided on the batching plate 51; among them, the gasket is an ordinary standard gasket, and using the gasket as the recognition point for visual recognition and positioning has the advantage of low cost; specifically, two recognition and positioning holes 512 for cooperating with the gasket are provided on the batching plate 51, and the magnetic plate 52 is also arranged below the recognition and positioning holes 512, so that the gasket contacts the magnetic plate 52, which can ensure the stability of the gasket; of course, in other alternative embodiments, the gasket can also be fixed in other ways, such as being clamped in the batching plate 51 or pasted on the batching plate 51, which is not limited here; specifically, in this embodiment, the positions of multiple screw positioning holes 511 on the batching plate 51 are associated with the positions of the two gaskets. By the two gaskets, a plane coordinate system can be established on the batching plate 51, and the position of each screw positioning hole 511 on the plane coordinate system is fixed, so as to facilitate placing the screws into the corresponding screw positioning holes 511.

[0064] Refer to Figure 1 , in this embodiment, the feeding mechanism 1 is used to store and convey empty batching boxes 5, and the screw batching mechanism 2 is connected to the feeding mechanism 1, that is, the feeding mechanism 1 conveys the empty batching boxes 5 to the screw batching mechanism 2; in this embodiment, the discharging mechanism 4 is used to receive the batching boxes 5 that have completed batching, and the discharging mechanism 4 is connected to the gasket batching mechanism 3, that is, the gasket batching mechanism 3 conveys the batching boxes 5 that have completed batching to the discharging mechanism 4.

If the first barcode scanner 6 cannot scan out the identification code 55 on the batching box 5, it is fed back to the PLC controller, and the PLC controller controls the screw batching mechanism 2 to directly convey the empty batching box 5 to the discharging mechanism 4.

[0066] Refer to Figures 1 to 13, specifically, the screw batching mechanism 2 includes a screw batching bench 21, and a first platen 211 is arranged on the screw batching bench 21; a first batching box conveying component 221 on the first platen 211, and the first batching box conveying component 221 is used to receive the batching box 5 from the feeding mechanism 1 and convey the batching box 5 to the gasket batching mechanism 3 after the screw batching is completed; the screw batching mechanism 2 further includes a plurality of screw blowing machines 291 and a blowing machine bench 293 for carrying the screw blowing machines 291; the screw blowing machines 291 are used to store and blow screws, and a guiding hose 292 is arranged on the screw blowing machines 291; a screw receiving component 23 is arranged on the screw batching bench 21, and the screw receiving component 23 includes a plurality of screw tracks arranged side by side; the screw tracks are arranged obliquely, and a positioning cylinder 24 communicated with the guiding hose 292 is arranged at the upper end of the screw track, and a positioning component 235 is arranged at the lower end of the screw track; the screw blowing machine 291 blows the screws into the guiding hose 292, the screws are discharged from the guiding hose 292 and then pass through the positioning cylinder 24 and fall on the screw track with the screw head facing up, and then the screws move downward along the screw track under the action of their own weight until they contact the positioning component 235; a screw flipping component 25 is arranged on the first platen 211, and the screw flipping component 25 is used to clamp the screws on the screw track and adjust the posture of the screws to a vertical state with the screw head facing down; a screw placing component 26 is arranged at the inner top of the screw batching bench 21, and the screw placing component 26 is used to clamp the screws on the screw flipping component 25 and place the screws into the batching box 5.

[0067] Referring to Figures 1 to 13 , specifically, in this embodiment, the first batching box conveying component 221 includes two conveying belts arranged at intervals; a lifting component 223 and a stop component 224 located between the two conveying belts are further arranged on the first platen 211; after the batching box 5 is conveyed from the feeding mechanism 1 to the first batching box conveying component 221, the stop component 224 rises, the batching box 5 is conveyed to contact the stop component 224, then the first batching box conveying component 221 stops conveying, and then the lifting component 223 jacks up the batching box 5; four fixed baffles 222 are arranged on the first batching box conveying component 221, and two fixed baffles 222 are arranged on one side; the lifting component 223 jacks up the batching box 5 until it contacts the fixed baffles 222, so as to clamp and fix the batching box 5; after the batching box 5 is jacked up, it is separated from the conveying belt and clamped and fixed, which is beneficial to accurately placing the screws into the screw positioning holes 511.

[0068] Referring to Figures 1 to 13, in this embodiment, a screw blowing machine 291 is used for storing and feeding screws. The screw blowing machine 291 is connected to the positioning cylinder 24 through a material guiding hose 292. Therefore, the screw blowing machine 291 can be arranged independently of the screw batching bench 21, which is convenient for optimizing the volume of the screw batching bench 21. At the same time, a large number of screw blowing machines can be arranged to store screws of different specifications respectively, so as to improve the application range of the system. In this embodiment, a screw receiving component 23 is arranged on the screw batching bench 21 to receive the screws blown out from the material guiding hose 292. The screw receiving component 23 includes a plurality of screw tracks arranged in parallel, which is beneficial to reducing the volume of the screw receiving component 23. The inclined screw tracks can, on the one hand, adjust the posture of the screws to facilitate the subsequent handling and turnover of the screws, and on the other hand, use their own weight to realize the movement of the screws, which can simplify the structure and is convenient for arrangement. The positioning cylinder 24 is connected to the material guiding hose 292, and the positioning cylinder 24 can preliminarily correct the posture of the screws discharged from the material guiding hose 292, so that the screws can fall smoothly on the screw tracks.

[0069] Refer to Figures 1 to 13 , specifically, in this embodiment, four blowing machine benches 293 are arranged, and each blowing machine bench 293 is a three-layer structure. A hose support for arranging the material guiding hose 292 is provided at the top of the blowing machine bench 293, which can realize the neat arrangement of multiple material guiding hoses 292. In this embodiment, four screw receiving components 23 are arranged on the screw batching bench 21, and the four screw receiving components 23 are respectively arranged on both sides of the screw batching bench 21. Two screw receiving components 23 arranged at intervals are provided on one side, which is beneficial to arranging more screw receiving components 23 on the screw batching bench 21. In this embodiment, the numbers of the screw blowing machine 291 and the screw tracks can be adjusted according to needs, and no limitation is made here. The screw blowing machine 291 in this embodiment belongs to the prior art and will not be elaborated here.

[0070] Refer to Figures 1 to 13, in this embodiment, a screw track includes two guide plates 232 arranged in parallel, that is to say, the screw receiving assembly 23 includes a plurality of guide plates 232 arranged in parallel; after the screw falls on the screw track, the screw is embedded between the two guide plates 232, and the screw head contacts the top walls of the two guide plates 232 at the same time; that is to say, when the screw moves on the screw track, the screw head faces upward; using two guide plates 232 to form the screw track has a simple structure and is convenient for arrangement; when the screw moves on the screw track, the screw is embedded between the two guide plates 232, and the screw head contacts the top wall of the guide plate 232, which is beneficial to improving the stability of the screw movement; of course, in other alternative embodiments, two adjacent screw tracks can also share a guide plate, which is not limited here; the screw receiving assembly 23 further includes a first support frame 231 and a second support frame 237, the second support frame 237 is connected to the screw batching bench 21, and an angle plate 238 is arranged between the first support frame 231 and the second support frame 237; a fixed support plate 233 connected to the guide plate 232 is arranged on the first support frame 231; the first support frame 231 and the second support frame 237 are connected by the angle plate 238, so as to facilitate adjusting the inclination angle of the screw track, so that the screw can move smoothly downward under its own weight; preferably, a limit pressing plate 234 matched with the screw head is arranged above the screw track, the limit pressing plate 234 extends upward from the lower end of the screw track, and the length of the limit pressing plate 234 is less than the length of the screw track; arranging the limit pressing plate 234 above the lower end part of the screw track, and the limit pressing plate 234 is arranged in parallel with the guide plate 232, which can limit the screw and prevent the screw from jumping out of the screw track or turning over under the action of inertia; specifically, the limit pressing plate 234 is provided with a bending part connected to the side wall of the guide plate 232, so that the limit pressing plate 234 can be located above the guide plate 232.

[0071] Refer to Figures 1 to 13, specifically, in this embodiment, the positioning component 235 includes a positioning baffle 2351 installed on the first support frame 231. The positioning baffle 2351 extends between the two guide plates 232 and is used to position the threaded post of the screw. The positioning component 235 further includes an auxiliary fixing plate 2352 provided on the positioning baffle 2351. A positioning screw 2353 is provided on the auxiliary fixing plate 2352 and is used to position the screw head of the screw. That is to say, when the screw moves from the screw track to the lower end, the threaded post of the screw contacts the positioning baffle 2351, and the screw head of the screw contacts the positioning screw 2353. This is conducive to ensuring the stability and consistency of the screw posture, thus facilitating the clamping of the screw. Preferably, two notches are symmetrically provided at the end of the positioning screw 2353, so that a stop baffle 2354 in contact with the screw head is formed at the end of the positioning screw 2353, and the stop baffle 2354 is vertically arranged.

Specifically, the positioning screw 2353 passes through the auxiliary fixing plate 2352, and two nuts are screwed on the positioning screw 2353 on both sides of the auxiliary fixing plate 2352 respectively. The two nuts are used to lock the positioning screw 2353, and at the same time, it is also convenient to adjust the angle of the positioning screw 2353 to make the stop baffle 2354 in a vertical state. The limit pressing plate 234, the positioning baffle 2351 and the two guide plates 232 cooperate to form an open screw picking port at the lower end of the screw track. After the screw contacts the positioning component 235, it is located at the screw picking port. At this time, the screw head is exposed, and the limit pressing plate 234 does not block the screw head, thus facilitating the removal of the screw from the screw track.

That is to say, a plurality of screws are pre-set in the buffer area on the screw tracks, which is conducive to improving production efficiency. When the screws at the lower end of the screw track are taken out, the screws in the buffer area will move down by one screw position. At this time, the proximity sensors 236 cannot detect the screws, so a signal will be sent to the screw blowing machine 291, and the screw blowing machine 291 will perform a blowing action to supplement the screws. When the proximity sensors 236 detect the screws again, a signal will be sent to the screw blowing machine 291, and the screw blowing machine 291 will stop the blowing action. That is to say, the proximity sensors 236 serve as switches for the screw blowing machine 291 to keep the buffer area in a full-load state all the time, thereby improving production efficiency.

[0079] Refer toFigures 1 to 14 , the gasket batching process specifically includes transporting the batching box 5 that has completed screw batching to the gasket batching mechanism 3. The second barcode scanner scans the identification code 55 on the batching box 5 and transmits it to the PLC controller. The PLC controller interacts with the human-machine interaction device to obtain the corresponding gasket formula, and then the PLC controller controls the gasket batching mechanism 3 to sequentially sleeved gaskets onto the corresponding screws in the batching plate 51. Specifically, the gasket batching mechanism 3 includes a gasket batching bench. A second platen is arranged on the gasket batching bench. A second batching box conveying component is arranged on the second platen. The second batching box conveying component is used to receive the batching box 5 from the first batching box conveying component 221 and convey the batching box 5 to the blanking mechanism 4 after the gasket batching is completed. A gasket feeding component 31 is arranged on the second platen. A gasket placing component is arranged at the inner top of the gasket batching bench. The gasket placing component is used to clamp the gaskets on the gasket feeding component 31 and sleeve the gaskets onto the screws in the batching box 5. The gasket placing component includes a second robotic arm and a gasket clamping component and a second vision recognition component arranged at the end of the second robotic arm. Except for the gasket feeding component 31, the rest of the structures are not shown in the drawings. The structure of the second batching box conveying component is the same as that of the first batching box conveying component 221. Among them, the gasket feeding component 31 adopts a flexible feeder based on vision recognition, which belongs to the prior art and will not be elaborated here. Compared with screws, the number of gasket specifications is less, and it is also convenient for feeding and clamping. Therefore, multiple gasket feeding components 31 are used, and each gasket feeding component 31 provides gaskets of multiple specifications, which can meet the gasket batching requirements.

[0080] The working principle is as follows:

[0081] Customize the batching box according to different assembly parts to realize the one-to-one association of the assembly parts, screw formula, gasket formula, identification code, batching box, and batching plate. This can not only effectively avoid the problem of batching errors but also facilitate the realization of automatic batching of screws and gaskets.

[0082] During batching, the operator places the batching box 5 on the feeding mechanism 1. The feeding mechanism 1 conveys the batching box 5 to the screw batching mechanism 2. The screw batching mechanism 2 performs the screw batching process to realize the automatic batching of screws. After the screw batching is completed, the screw batching mechanism 2 conveys the batching box 5 to the gasket batching mechanism 3. The gasket batching mechanism 3 performs the gasket batching process to realize the automatic batching of gaskets. After the gasket batching is completed, the gasket batching mechanism 3 conveys the batching box 5 to the blanking mechanism 4, and then the operator takes away the batching box 5 on the blanking mechanism 4.

[0083] That is to say, after the customization of the ingredient box is completed, the operator only needs to place the empty ingredient box and collect the ingredient box with ingredients completed. The ingredient work of screws and gaskets is automatically completed by the screw and gasket ingredient system, which can improve production efficiency and reduce the risk of ingredient errors.
