Description

Technical Field

[0001] This invention relates to the field of bolt adhesive application technology, and more particularly to a bolt adhesive application device. Background Technology

[0002] In the field of mechanical assembly, the threaded part of bolts usually needs to be coated with lubricant or locking agent to reduce or increase the assembly or disassembly torque. Especially when it comes to applying lubricant or locking agent to large bolts and a large number of bolts, the large bolts are heavy and have large dimensions, so manual operation alone leads to low efficiency and high labor intensity.

[0003] In response, Chinese invention patent application CN101757999A discloses an automatic bolt gluing machine, including a frame, a gluing wheel, and a transmission device. The gluing wheel and the transmission device are mounted on the frame. The output shaft of the transmission device is connected to the gluing wheel. The lower part of the gluing wheel extends into a glue storage tray. The automatic bolt gluing machine also includes a turntable. At least two electromagnetic chucks for clamping bolts to be processed are distributed around the turntable. A passive drive wheel is fixedly installed on one side of the electromagnetic chuck. The passive drive wheel is linked with an active drive wheel. The active drive wheel is connected to the tail end of the output shaft of the transmission device. The position of the bolt to be glued is in contact with the gluing wheel.

[0004] During operation, the electromagnetic chuck clamps the bolt and rotates with the turntable. When the bolt rotates to the position of the glue-applying wheel, the electromagnetic chuck rotates under the drive of the driven wheel, thus causing the bolt to rotate as well. During this rotation, the bolt contacts the glue-applying wheel, completing the glue application. In the comparison document, the bolt needs to rotate under the drive of a series of complex transmission mechanisms, including a drive wheel and a driven wheel, during glue application. The complex structure of the transmission mechanism increases manufacturing costs. Furthermore, after glue application, each bolt needs to be unloaded individually, and then manually stacked, resulting in low operational efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a bolt gluing device, which mainly solves the technical problem that the bolt gluing device in the prior art requires a complex transmission mechanism to rotate the bolt, resulting in high manufacturing costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bolt gluing device includes a frame with a gluing mechanism mounted on it. A bolt conveying mechanism for linearly conveying bolts is located on one side of the gluing mechanism. The bolt conveying mechanism has a support structure for the bolt shank to pass through and for supporting the bolt head. A bolt stop is also fixedly mounted on the frame to contact the bolt head during conveying and force the bolt to rotate. The gluing mechanism is located below the bolt stop and is used to apply gluing to the bolt shank during or after rotation.

[0008] The beneficial effects of the above technical solution are as follows: by setting a support structure on the bolt output mechanism, the bolt shank can pass through and support the bolt head, thus achieving stable support for the bolt and supporting the bolt to rotate within the support structure; by using the bolt stop fixed on the frame, the bolt can rotate within the support structure after contacting the bolt stop during the bolt conveying process, so as to facilitate the glue application mechanism to complete the glue application operation on the bolt. The mechanism for rotating the bolt in this solution is simpler and more ingenious than the existing technology and does not require an additional drive mechanism, which helps to reduce manufacturing costs.

[0009] As a further optimized technical solution, the bolt conveying mechanism includes a circulating conveyor and a conveying wheel, the circulating conveyor being wound around the conveying wheel, and the support structure being disposed on the circulating conveyor.

[0010] The beneficial effects of the above technical solution are: it facilitates the cyclical operation of the conveying mechanism and improves work efficiency.

[0011] As a further optimized technical solution, the support structure is a support block, and the support block is provided with a U-shaped groove with an opening facing the glue application mechanism. The U-shaped groove allows the shank of the bolt to pass through. One side wall of the U-shaped groove is inclined outward to form an inclined groove wall, so that when the bolt on the circulating conveyor moves to the position corresponding to the conveyor wheel, it slides outward along the inclined groove wall.

[0012] The beneficial effects of the above technical solution are as follows: using a U-shaped groove facilitates the placement of bolts into the support structure; the opening of the U-shaped groove faces the glue application mechanism to prevent the bolts from being pushed off when the glue application mechanism applies glue; and one side wall of the U-shaped groove is tilted outward so that the bolts that have been glued by the glue application mechanism can be automatically unloaded from the U-shaped groove as the circulating conveyor rotates, thereby improving the unloading efficiency.

[0013] As a further optimized technical solution, the bolt gluing device also includes a bolt collecting mechanism, which is located on one side of the bolt conveying mechanism and is used to receive bolts that slide down from the U-shaped groove.

[0014] The beneficial effect of the above technical solution is that it facilitates the automatic collection of bolts after adhesive application.

[0015] As a further optimized technical solution, the bolt collecting mechanism includes a collecting guide rail and a storage device. The storage device includes at least two parallel spaced support rods, each of which is horizontally arranged. The gap between two adjacent support rods is used to accommodate the shank of the bolt, and the top surface of the support rod is used to support the head of the bolt. The collecting guide rail includes two parallel spaced guide rods, the gap between which allows the shank of the bolt to pass through. One end of the two guide rods is used to connect with the U-shaped groove on the corresponding support structure, and the other end connects with the ends of the two corresponding support rods.

[0016] The beneficial effects of the above technical solution are as follows: by setting up a bolt collecting mechanism, the bolts that have been coated with glue can slide from the U-shaped groove onto the collecting guide rail, and then slide along the collecting guide rail onto the storage device, thereby improving the unloading efficiency. By setting up two parallel and spaced support rods and connecting the two support rods to the collecting guide rail, the bolts falling from the support structure can slide along the collecting guide rail into the gap between the two support rods, and automatically stack neatly in the gap between the two support rods under the action of the kinetic energy generated during the sliding process of the bolts on the collecting guide rail.

[0017] As a further optimized technical solution, the bolt gluing device also includes a bolt collecting mechanism, which is located below the bolt conveying mechanism and is used to receive bolts that fall from the support structure.

[0018] The advantages of the above technical solution are: this solution can be used when there is no need to stack bolts. A bolt collection mechanism can be set directly below the bolt conveying mechanism. When the bolts after the glue has been applied rotates with the bolt conveying mechanism to the bottom of the conveyor wheel, the bolts will automatically fall from the support structure into the bolt collection mechanism, resulting in high unloading efficiency.

[0019] As a further optimized technical solution, multiple support structures are provided, and the multiple support structures are arranged in parallel along the conveying direction of the bolt conveying mechanism.

[0020] The beneficial effects of the above technical solution are as follows: In order to improve the glue application efficiency, multiple support structures are arranged in parallel, which facilitates continuous glue application to multiple bolts, improves the continuity of the glue application operation, and thus improves work efficiency.

[0021] As a further optimized technical solution, the glue application mechanism includes a glue application brush and a glue replenishing mechanism for adding glue to the glue application brush. Multiple glue application brushes are arranged at intervals along the conveying direction of the bolt conveying mechanism, and multiple bolt stops are also provided, each corresponding to one of the glue application brushes.

[0022] The beneficial effects of the above technical solution are: setting up multiple glue brushes in conjunction with bolt stops makes it convenient to apply glue to each bolt at various angles in a timely manner, and can ensure sufficient glue application.

[0023] As a further optimized technical solution, the bolt stop is a stop bar, the top end of which is fixedly connected to the frame, and the lower end of which is used to contact the head of the bolt.

[0024] The advantages of the above technical solution are: the use of a stop bar structure is simple and convenient for processing and installation.

[0025] As a further optimized technical solution, the circulating conveyor is a transmission chain, and the conveyor wheel is a sprocket.

[0026] The beneficial effects of the above technical solution are: the transmission chain is stable, which can ensure the smooth progress of the glue application operation. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0036] Example 1 of the bolt adhesive applicator of the present invention:

[0037] like Figure 1 and Figure 2 As shown, the bolt gluing device includes a frame 1, on which a gluing mechanism is installed for applying glue to bolts; a bolt conveying mechanism is installed on one side of the gluing mechanism for linearly conveying bolts, for applying glue to bolts that need to be glued during linear conveying; a bolt stop 3 is also fixedly installed on the frame 1 for contacting the head of the bolt during conveying and forcing the bolt to rotate; the gluing mechanism is located below the bolt stop 3 for applying glue to the shank of the bolt during or after rotation; a bolt collecting mechanism is installed at one end of the conveying mechanism for collecting the bolts that have been glued.

[0038] The bolt conveying mechanism specifically includes a circulating conveyor 4 and a conveyor wheel 5. The circulating conveyor 4 is wound around the conveyor wheel 5, and the conveyor wheel 5 drives the circulating conveyor to circulate repeatedly. In this embodiment, the circulating conveyor 4 is a transmission chain, and the conveyor wheel 5 is a sprocket. Multiple support structures 2 are provided on the transmission chain to allow the bolt shank to pass through and to support the bolt head, facilitating the transmission of the bolt by the transmission chain. To improve the efficiency of applying adhesive to the bolts, multiple support structures 2 can be provided and evenly distributed along the transmission chain.

[0039] In this embodiment, the support structure 2 is a support block. The support block is provided with a U-shaped groove 21 with an opening facing the glue application mechanism. The U-shaped groove 21 allows the bolt shank to pass through. One side wall of the U-shaped groove 21 is inclined outward to form a sloping groove wall, so that when the bolt on the transmission chain moves to the position corresponding to the sprocket, it slides outward along the sloping groove wall. The specific principle of the bolt falling off automatically is as follows: the bolt is transmitted to the rear end of the transmission chain in the U-shaped groove 21. When it is transmitted to the position where the transmission chain and the sprocket mesh, the U-shaped groove 21 begins to tilt. The bolt begins to slide under its own weight. Under the guidance of the sloping groove wall, when the transmission chain and the sprocket mesh to a certain position, the bolt automatically slides off from the U-shaped groove. The exact position where the bolt slides off depends on many factors such as the size of the bolt, the inclination angle of the sloping groove wall, and the surface smoothness. For different bolts, the exact position where the bolt falls off needs to be specifically tested during on-site equipment installation.

[0040] like Figure 4 As shown, the glue application mechanism includes a glue application brush 8 and a glue replenishing mechanism 9 for adding glue to the glue application brush 8. The glue replenishing mechanism 9 stores glue and completes the automatic glue replenishing action by continuously pushing the glue outward. The structure of continuously pushing the glue outward is very common in the prior art and will not be described in detail here. The glue outlet end of the glue replenishing mechanism 9 is connected to a glue delivery pipe 10. The other end of the glue delivery pipe 10 is installed above the glue application brush 8, so that glue can be continuously added to the glue application brush 8. Multiple glue application brushes 8 are arranged at intervals along the conveying direction of the bolt conveying mechanism so as to apply glue to the bolts evenly and fully. Multiple bolt stops 3 are also provided and correspond one-to-one with the glue application brushes 8.

[0041] Specifically, in this embodiment, the bolt stop 3 is a stop bar. The top of the stop bar is fixedly connected to the frame 1, and the lower end of the stop bar is used to touch the head of the bolt. During the glue application process, as the bolt is conveyed forward, the rod touches the glue brush 8 and is coated with glue. When the head passes the position of the stop bar, it is deflected and rotated at an angle. The glue brush 8 and the stop bar are in one-to-one correspondence, so that each glue brush can be provided with a stop bar on the rear side along the conveying direction, so that after the rod is coated with glue at an angle, it is rotated at an angle by the stop bar and continues to be coated with glue by the subsequent glue brush 8. After such a cycle is repeated a certain number of times, it is ensured that the rod is fully coated with glue. Alternatively, a glue brush can be installed below each stop bar, and the glue brush applies glue to the rod during the process of the stop bar deflecting the bolt.

[0042] To facilitate the collection of automatically removed bolts, the bolt gluing device also includes a bolt collection mechanism. The bolt collection mechanism is located on one side of the bolt conveying mechanism and docks with the U-shaped groove 21 to automatically collect the bolts conveyed from the bolt conveying mechanism.

[0043] like Figure 3As shown, the bolt collection mechanism includes a collection guide rail 6 and a storage device 7. The collection guide rail 6 is fixedly mounted on one side of the bolt conveying mechanism via a guide rail bracket 61. The storage device 7 includes at least two parallel and spaced support rods 71, each of which is horizontally arranged. The gap 72 between two adjacent support rods 71 ​​is used to accommodate the shank of the bolt, and the top surface of the support rod 71 is used to support the head of the bolt. In this embodiment, the storage device is a collection trolley, on which multiple support rods 71 ​​are arranged side by side. The collection guide rail 6 includes two parallel and spaced guide rods, with the gap between the two guide rods allowing the shank of the bolt to pass through. One end of each guide rod is used to connect with the U-shaped groove 21 on the corresponding support structure 2, and the other end connects with the ends of the corresponding two support rods 71.

[0044] In specific work, Figure 1 Bolts to be coated with adhesive are placed in the U-shaped groove on the support block at the upper right end of the transmission chain. The bolts are conveyed forward with the transmission chain. During the conveying process, the rod touches the adhesive brush, thus applying adhesive to the rod. As the bolts continue to be conveyed forward, the hexagonal bolt head touches the stop bar. Under the action of the stop bar, the bolt rotates at a certain angle in the U-shaped groove, so that the uncoated part faces the adhesive brush. During the forward conveying process, the bolts are coated with adhesive by the subsequent adhesive brush. After being coated with adhesive, the bolts are conveyed to the front end with the transmission chain and then slide down from the U-shaped groove onto the collection guide under the action of gravity. They slide along the collection guide to the interval between two adjacent support rods and are neatly arranged in the interval. When the bolts fill one interval, the vehicle can be pushed to the end of the collection guide to connect with another interval.

[0045] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that in embodiment 1 the circulating conveyor is a transmission chain and the conveyor wheel is a sprocket, while in this embodiment the circulating conveyor is a transmission belt and the conveyor wheel is a pulley.

[0046] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that in embodiment 1 the bolt stop is a stop bar, which is vertically arranged. In this embodiment, the stop bar can also be horizontally arranged. One end of the stop bar is fixedly connected to the frame, and the other end is arranged on one side above the transmission chain. When the bolt is transmitted with the transmission chain, the hexagonal bolt head touches one end of the stop bar and rotates at an angle in the U-shaped groove before continuing to be transmitted backward. The bolt stop is not limited to a stop bar, but can also be a baffle or other shaped components, as long as it can play a role in turning the bolt during the transmission chain.

[0047] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that the gluing mechanism in embodiment 1 includes a gluing brush and a glue replenishing mechanism for adding glue to the gluing brush. In this example, the gluing mechanism may only include a gluing brush, and glue may be replenished directly to the gluing brush by manual glue replenishment. Of course, the gluing mechanism may also include a nozzle, and glue may be applied by spraying.

[0048] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that in embodiment 1, multiple support structures are provided. In this embodiment, there can also be two or one. By increasing the conveying speed of the conveyor chain, the gluing efficiency can also be improved.

[0049] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that the bolt collecting mechanism in embodiment 1 includes a collecting guide rail and a storage device. In this embodiment, the bolt collecting mechanism is located below the bolt conveying mechanism and can be a collecting box or a collecting basket for receiving bolts that fall from the support structure.

[0050] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that the support rod is set horizontally in embodiment 1. In this embodiment, the side of the support rod that is connected to the collecting guide rail can be tilted upward at a certain angle. This is more conducive to the bolts that slide down through the collecting guide rail being clustered and arranged at intervals between two adjacent support rods. When the moving vehicle body is pushed in the future, the bolts are less likely to slip off from the horizontal through groove.

[0051] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that the bolt gluing device in embodiment 1 is provided with a bolt collecting device. In this embodiment, the bolt collecting mechanism may not be provided.

[0052] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that a U-shaped groove is opened on the support block in embodiment 1. In this embodiment, a through hole is opened on the support block. The through hole allows the shank of the bolt to pass through, and the top of the through hole can support the head of the bolt. At this time, the bolt can be manually picked up. Of course, if it is a circulating conveyor, when the bolt is conveyed to a certain position, it can slide off the support structure on its own.

[0053] In other embodiments of the bolt gluing device: The difference between this embodiment and embodiment 1 is that the bolt conveying mechanism in embodiment 1 includes a ring conveyor and a conveying wheel. In this embodiment, the bolt conveying mechanism is a linear reciprocating conveying mechanism. During the process, the bolts are glued. After the process is completed, the glued bolts are unloaded and the device returns to the starting position to reload and glu. This process is repeated cyclically.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
