Description

Technical Field

[0001] This invention belongs to the field of automatic feeding technology, and particularly relates to a feeding and dispensing device and a fastening workstation. Background Technology

[0002] Currently, some workpieces require a skin to be applied to their surface for purposes such as protection, decoration, or improved aerodynamic performance. This skin is typically securely fastened to the workpiece surface using threaded fasteners (such as bolts and screws). To ensure good anti-loosening and sealing performance of the threaded fasteners after installation, adhesive must be applied to the threaded areas before screwing them in.

[0003] Currently, the above-mentioned thread coating operation mainly relies on manual labor. Operators use a glue gun or glue pen to manually coat the threaded parts of each threaded fastener. However, this manual glue application method has obvious shortcomings: the operation is repetitive and monotonous, requiring operators to maintain a high level of attention for extended periods, resulting in high labor intensity and fatigue; manual glue application is inefficient and cannot meet the cycle time requirements of mass production. In addition, the amount of glue applied, the application location, and the uniformity of the glue application are greatly affected by the operator's experience and condition, easily leading to quality problems such as missed coating, excessive or insufficient glue application, resulting in unstable anti-loosening and sealing effects after the fasteners are tightened, thus affecting the reliability of the connection between the skin and the workpiece. Summary of the Invention

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] The feeding and dispensing equipment and the fastening workstation of the present invention are described below with reference to the accompanying drawings.

[0024] As 1 to Figure 4 As shown, the present invention provides a material dispensing device, wherein the material dispensing device includes: The feeding device 100 has a feeding port for the side discharge of the parts to be coated with adhesive 800; The material dispensing device 200 is located outside the feeding port and has a first positioning opening 214 formed at the upper end. The first positioning opening 214 is used for the rod part of the part to be coated with glue 800 to enter, and the periphery of the first positioning opening 214 is used to support the head of the part to be coated with glue 800 upward. The dispensing device 300 has a dispensing station for positioning the part to be coated 800 and is configured to perform dispensing operation on the rod of the part to be coated 800 at the dispensing station. The transfer device 400 is configured to pick up the head of the part to be coated with glue 800 on the dispensing device 200 and transfer the part to be coated with glue 800 to the dispensing station.

[0025] Through the above technical solution, the material feeding and dispensing equipment provided by the present invention has the following beneficial effects: When using the above-mentioned dispensing equipment, the equipment includes a feeding device 100, a dispensing device 200, a dispensing device 300, and a transfer device 400. The feeding device 100 can automatically feed the part to be coated 800 into the feeding port, and the part to be coated 800 can fall from the feeding port into the first positioning opening 214 of the dispensing device 200. The periphery of the first positioning opening 214 supports the head of the part to be coated 800, realizing automatic dispensing and positioning of a single part to be coated 800. Then, the transfer device 400 can automatically grab the dispensed part to be coated 800 from the dispensing device 200 and transfer it. The part is moved to the dispensing station of the dispensing device 300, where the dispensing device 300 automatically completes the dispensing operation on the rod of the part to be glued 800. The entire process requires no manual intervention. Compared with the traditional manual glue application method, it can significantly reduce the labor intensity of operators and significantly improve the glue application efficiency, which can meet the cycle time requirements of mass production. At the same time, through automatic positioning and automatic glue application, the glue application position, glue application amount and glue application uniformity can remain stable and will not be affected by human factors. It effectively avoids quality problems such as missed application, excessive or insufficient glue application, and ensures the subsequent anti-loosening and sealing effect of the part to be glued 800, improving the connection reliability between the skin and the workpiece.

[0026] Specifically, when the part to be coated with adhesive 800 is a bolt, the feeding device 100 can be an automatic bolt feeder, preferably a vibratory feeder. In addition, the feeding and dispensing equipment also includes a fixed frame. The feeding device 100, the dispensing device 200, the dispensing device 300 and the transfer device 400 can be integrated on the fixed frame. The first positioning opening 214 may include, but is not limited to, being semi-circular, but it must be ensured that the lateral opening size allows the rod to enter, and the periphery of the first positioning opening 214 allows the head to overlap.

[0027] See Figures 1 to 4 In one embodiment of the present invention, the dispensing device 200 includes a dispensing rack 210 and a dispensing clamping mechanism 220. The dispensing rack 210 is disposed outside the feed port and forms a first positioning opening 214. The dispensing clamping mechanism 220 is used to clamp or release the rod portion of the part to be coated 800 on the lower side of the first positioning opening 214. By adding the dispensing clamping mechanism 220, when the part to be coated 800 falls from the feed port into the first positioning opening 214, the dispensing clamping mechanism 220 can clamp the rod portion of the part to be coated 800 in time, preventing the part to be coated 800 from shaking or even tilting before the transfer device 400 can grab it, thus improving the stability of the dispensing and positioning and ensuring that the transfer device 400 can successfully grab the part to be coated 800. Understandably, after the transfer device 400 switches to the top of the dispensing device 200 to grab the head of the part to be coated 800, the dispensing clamping mechanism 220 can loosen the clamping of the rod of the part to be coated 800 so that the transfer device 400 can lift the part to be coated 800 from bottom to top, so that the part to be coated 800 can smoothly detach from the dispensing device 200.

[0028] In one embodiment of the present invention, the dispensing device 200 further includes a lifting drive 230, which is drivenly connected to the dispensing clamping mechanism 220 and is used to drive the dispensing clamping mechanism 220 to perform lifting movements. By adding the lifting drive 230, the dispensing clamping mechanism 220 can lift the entire part 800 after clamping the rod portion of the part to be coated, allowing the head of the part 800 to be lifted away from the periphery of the first positioning opening 214. This corrects the posture deviation of the part 800 caused by the material falling in, and also ensures higher positional accuracy when the subsequent transfer device 400 grasps it, preventing the head from getting caught on the periphery of the first positioning opening 214 and hindering successful grasping. Simultaneously, the position of the part 800 after lifting is more uniform, adapting to the grasping height requirements of the transfer device 400. Furthermore, the lifting drive 230 may include, but is not limited to, a lifting cylinder.

[0029] In one embodiment of the present invention, the material distribution clamping mechanism 220 and the lifting drive member 230 are both provided on the material distribution frame 210, and the upper end of the material distribution frame 210 extends upward to provide a material stop block 215. The material stop block 215 is spaced apart from the first positioning opening 214. The material distribution device 200 also includes a material distribution translation module 240, which is drivenly connected to the material distribution frame 210 and is used to drive the material distribution frame 210 to move to one of the first positioning opening 214 and the material stop block 215, which is positioned opposite to the feeding port. In this way, after the part to be coated 800 is divided into sections at the first positioning opening 214 and clamped by the section clamping mechanism 220, the section translation module 240 can drive the section rack 210 to move as a whole, so that the stop block 215 moves to a position opposite to the feed port. At this time, the next part to be coated 800 coming out of the feed port will be blocked and stopped by the stop block 215 and will not continue to be sent out. Only when the part to be coated 800 that has been divided is taken away by the transfer device 400 will the section translation module 240 drive the section rack 210 to reset, so that the first positioning opening 214 is aligned with the feed port again, and the next part to be coated 800 can fall into the first positioning opening 214 for sectioning. This achieves intermittent sectioning of a single part to be coated 800, avoids multiple parts to be coated 800 falling at one time and causing jamming, and ensures that the sectioning process is orderly and stable.

[0030] Furthermore, the material distribution translation module 240 can be configured as a linear module or a translation cylinder, etc. When the material distribution translation module 240 adopts a translation cylinder, the material distribution frame 210 is moved and installed on the material distribution slide rail 241, and the translation cylinder is driven and connected to the material distribution frame 210.

[0031] In one embodiment of the present invention, the material distribution rack 210 includes a material distribution base plate 211, a material distribution upright plate 212, and a material distribution horizontal plate 213. The material distribution horizontal plate 213 and the material distribution base plate 211 are respectively disposed at the upper and lower ends of the material distribution upright plate 212. The extending direction of the material distribution horizontal plate 213 is consistent with the driving direction of the material distribution translation module 240. The side of the material distribution horizontal plate 213 facing the feeding port is provided with a first positioning opening 214, and a material blocking block 215 extends from the upper end of the material distribution horizontal plate 213 at a distance from the first positioning opening 214. The lifting drive member 230 and the material distribution clamping mechanism 220 are arranged sequentially from bottom to top on the material distribution base plate 211. The material distribution base plate 211 can support the lifting drive component 230 and the material distribution clamping mechanism 220. Furthermore, by mounting the material distribution horizontal plate 213 on the material distribution base plate 211, the first positioning opening 214 and the stop block 215 can be easily formed. The structure is simple and easy to form. Specifically, two material distribution vertical plates can be used, positioned at opposite ends of the material distribution horizontal plate 213 to form a gate-shaped structure, ensuring structural stability. The gate-shaped structure is located at the end of the material distribution base plate 211 closest to the feeding port. The lifting drive component 230 is positioned on the material distribution base plate 211, avoiding the feeding port. The clamping part of the material distribution clamping mechanism 220 extends towards the lower side of the material distribution horizontal plate 213.

[0032] See Figure 3 and Figure 5In one embodiment of the present invention, the material dispensing clamping mechanism 220 includes a clamping drive member 221, a first clamping block 222, and a second clamping block 223. The clamping drive member 221 extends outward and is provided with two clamping fingers. The clamping drive member 221 is used to drive the two clamping fingers to perform a clamping action that moves closer together or a relaxing action that moves further apart. The first clamping block 222 and the second clamping block 223 are respectively disposed on the inner side of the two clamping fingers and are used to clamp or relax the rod of the part to be coated with glue 800. Both the first clamping block 222 and the second clamping block 223 are provided with clamping surfaces. The clamping surfaces include a clamping side surface 224 disposed facing the periphery of the rod. The clamping side surface 224 is arranged in an inwardly concave arc shape. Thus, the clamping side surface 224 can better adapt to the outer periphery of the rod of the part to be coated with glue, increase the clamping contact area, improve the uniformity of clamping force, and at the same time better ensure the centering effect of the rod, avoid the rod from tilting after clamping, and ensure the positional accuracy of subsequent material transfer gripping and glue dispensing. In addition to the clamping side surface 224, the clamping surface also includes a stop end surface 225 located at the lower end of the clamping side surface 224 and positioned towards the end of the rod. This stop end surface 225 axially limits the lower end of the rod of the part to be coated 800. Combined with the bearing capacity of the head by the periphery of the first positioning opening 214, this prevents the part to be coated 800 from accidentally falling, further improving the stability of the material distribution and positioning. Furthermore, the clamping drive 221 can be specifically configured as a finger cylinder, with a simple and compact structure, facilitating installation. The first clamping block 222 and the second clamping block 223 can be made of flexible materials, such as polyurethane, to avoid affecting the external threads of the rod during clamping.

[0033] See Figure 1 and Figure 6 In one embodiment of the present invention, the dispensing device 300 includes a dispensing frame 310, a dispensing machine module 320, and a dispensing translation module 330. The dispensing frame 310 is provided with a dispensing station for vertically hanging the part 800 to be coated. The dispensing translation module 330 is drivenly connected to the dispensing machine module 320 and is used to drive the dispensing machine module 320 to approach or move away from the part 800 to be coated on the dispensing station. The dispensing machine module 320 is used to perform dispensing operations on the rod portion of the part 800 to be coated. This allows the part to be glued 800 to be hung vertically during the glue dispensing operation. The dispensing module 320 only needs to perform the glue dispensing operation on the rod of the part to be glued 800 at a suitable height position, so that the glue can flow down the rod to complete the glue application of the entire preset area of ​​the rod. There is no need for the dispensing module 320 to move axially along the rod, which simplifies the motion control process of the dispensing device 300, improves the glue application efficiency, and reduces the complexity of equipment control. Specifically, the dispensing translation module 330 includes, but is not limited to, a translation cylinder.

[0034] like Figure 6 and Figure 7As shown, in one embodiment of the present invention, the dispensing rack 310 includes a dispensing upright plate 311 and a dispensing horizontal plate 312. The lower end of the dispensing upright plate 311 is fixed, and the dispensing horizontal plate 312 is suspended above the dispensing upright plate 311. Specifically, the number of dispensing upright plates 311 can be set to two, and the two dispensing upright plates 311 are respectively arranged at opposite ends of the dispensing horizontal plate 312 to form a door-shaped structure. A second positioning opening 313, which is set as a dispensing station, is formed on the dispensing horizontal plate 312. The second positioning opening 313 is used for the rod part of the part to be coated with glue 800 to enter, and the periphery of the second positioning opening 313 is used to support the head of the part to be coated with glue 800 upward, so as to realize the vertical hanging and positioning of the part to be coated with glue 800 at the dispensing station. The structure is simple and the positioning is convenient. Specifically, the transfer device 400 can drive the part to be coated 800 to enter and exit the second positioning opening 313 from the side. The second positioning opening 313 can be configured as a long straight strip, and the inner wall of the inner end of the second positioning opening 313 can be configured to match the outer periphery of the rod, specifically as an arc shape.

[0035] See Figure 1 and Figure 8 In one embodiment of the present invention, the dispensing device 200 and the dispensing device 300 are arranged sequentially at intervals along a first direction. The transfer device 400 includes a transfer translation module 410, a lifting drive 420, and a transfer clamping mechanism 430 for clamping or releasing the head of the part to be coated 800. The transfer translation module 410 is located on one side of the dispensing device 200. The lifting drive 420 is mounted on the transfer translation module 410 and is used to drive the lifting drive 420 to move along the first direction. The transfer clamping mechanism 430 is mounted on the lifting drive 420 and is used to drive the transfer clamping mechanism 430 to move up and down above the dispensing device 200 or the dispensing device 300. Thus, the material transfer module 410 can drive the material transfer clamping mechanism 430 to move back and forth along the first direction between the material distribution device 200 and the dispensing device 300, completing the material picking and unloading actions. The lifting drive component 420 can cooperate to complete the lowering action during gripping and the lifting action after transfer. The overall structure is simple, the motion control is convenient, and it can stably realize the automatic transfer of the part to be coated 800 between the material distribution device 200 and the dispensing device 300. Specifically, the material transfer module 410 includes a translation drive component 411 and a translation cantilever frame 412 driven and connected to the translation drive component 411. The lifting drive component 420 is located at the upper end of the translation cantilever frame 412. The translation drive component 411 can be set as a linear module, and the lifting drive component 420 can be set as a lifting cylinder. The material transfer clamping mechanism 430 can adopt a structure similar to the aforementioned material distribution clamping mechanism 220, which uses a finger cylinder to drive the clamping block. The inner side of the clamping block can be provided with a clamping groove adapted to the shape of the bolt head.

[0036] Please see again Figures 1 to 4In one embodiment of the present invention, the feeding device 100 is provided with at least two feeding sections 110, which are arranged in parallel and each forms a feeding channel with a feeding port. The number of first positioning openings 214 on the dispensing device 200 is set to at least two, and the at least two first positioning openings 214 are respectively arranged in a one-to-one correspondence with the at least two feeding sections 110. Thus, during dispensing, each feeding section 110 can independently feed the part 800 to be coated with glue to the corresponding first positioning opening 214, and the dispensing and positioning of at least two parts 800 to be coated with glue can be completed in one operation. The subsequent transfer device 400 can also be set to grab and transfer all the parts 800 to be coated with glue to the dispensing device 300 at once to complete the dispensing operation, which can effectively improve the overall operation efficiency and adapt to the production needs of batch dispensing and fastening. Understandably, the number of material transfer clamping mechanisms 430 on the material transfer device 400, the number of second positioning openings 313 on the dispensing frame 310, and the number of dispensing machine modules 320 can all be set to at least two to match the setting of at least two first positioning openings 214, so that each part 800 to be coated can complete the corresponding processing steps at the same time without interfering with each other, thereby further improving processing efficiency while ensuring processing accuracy.

[0037] In addition, such as Figure 9 As shown, the present invention also provides a fastening workstation, which includes a turntable device 500, a fastening robot 600, and a feeding and dispensing device according to the above description. The turntable device 500 is used to carry the workpiece 900 to be fastened with a workpiece tray 701 and is configured to drive the workpiece 900 to be fastened to rotate circumferentially. The fastening robot 600 is used to pick up the glued part after the glued operation has been completed at the dispensing station and fasten the glued part to the workpiece 900 to be fastened. Since the fastening workstation adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] Specifically, the material feeding and dispensing equipment can automatically feed, divide, position, and dispense adhesive onto the parts to be glued (800). Then, the fastening robot (600) can directly grab the glued parts and automatically fasten them. At the same time, the turntable equipment (500) can rotate the workpieces to be fastened (900) to facilitate switching the fastening position.
