Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a conveying mechanism and a coating equipment including the conveying mechanism. Background Technology

[0002] In the prior art, in order to improve the hardness of the workpiece, it is usually chosen to coat the surface of the workpiece (such as coating the surface of the workpiece with titanium carbide). However, the height requirements of the film on the surface of the workpiece are different under different working conditions. When the existing workpiece conveying mechanism is conveying the workpiece, it can only convey the workpiece with the same coating requirement, which is difficult to meet the needs of multiple working conditions. Moreover, it is difficult to convey workpieces with different coating requirements in batches at the same time. Utility Model Content

[0003] To address the above problems, this utility model provides a conveying mechanism comprising:

[0004] The main body of the conveyor is used to transport the workpieces to be coated;

[0005] The chassis has multiple components arranged along the conveying direction of the conveyor body and connected to the conveyor body respectively;

[0006] Multiple positioning posts are fixed to the upper surface of the chassis;

[0007] A sleeve is used in conjunction with the positioning post. The lower part of the sleeve is hollow and fits around the outside of the positioning post. The upper part of the sleeve is hollow and forms a workpiece slot for inserting the workpiece. The height of the workpiece slot corresponds to the height of the part of the workpiece that extends out of the workpiece slot and is to be coated.

[0008] According to this technical solution, the height of the workpiece slot is the same as the height of the workpiece inserted into the slot. The height of the workpiece slot and the coating height of the portion of the workpiece extending out of the slot together constitute the overall height of the workpiece. Here, "corresponding" means that the height of the workpiece slot = overall height of the workpiece - coating height. By selecting a sleeve that matches the coating height of the workpiece (e.g., sleeve height = overall height of workpiece - coating height + height of positioning post), the sleeve is fitted over the positioning post. The workpiece is inserted into the sleeve, and the height of the workpiece extending out of the upper part of the sleeve is the coating height of the workpiece. Since the sleeve is fitted over the positioning post, installation and removal are convenient. Only a sleeve of appropriate height needs to be selected to load workpieces with different coating heights on the same or different chassis, meeting different coating height requirements and the needs of batch coating.

[0009] In the optional technical solution of this utility model, the conveyor body includes:

[0010] support;

[0011] The drive mechanism is fixedly mounted on the bracket;

[0012] The drive wheel is fixed to the drive mechanism and mounted on the top of the bracket. The axial direction of the drive wheel is the same as the height direction of the bracket.

[0013] The driven wheel is mounted on the bracket opposite to the driving wheel;

[0014] The belt is fitted over the drive pulley and the driven pulley.

[0015] According to the technical solution, the drive mechanism drives the drive wheel to rotate and drives the belt and driven wheel to rotate. The axial direction of the drive wheel is the same as the height direction of the support, that is, the belt is driven in the same plane. The above transportation method is beneficial to reduce the load on the belt and improve the single transportation capacity and service life of the conveyor body.

[0016] In the optional technical solution of this utility model, the chassis is located on the side of the conveyor body and is separated from the conveyor body by a specified distance, and the conveying mechanism further includes:

[0017] The guide rail is located on the outer periphery of the belt and is fixed to the bracket;

[0018] The roller assembly is slidably connected to the guide rail; and

[0019] An adapter is connected between the outer surface of the belt and the roller assembly.

[0020] According to this technical solution, by using an adapter to place the chassis on one side of the outer surface of the belt, the load on the belt is reduced, which helps to improve the service life of the conveyor body.

[0021] In an optional technical solution of this utility model, the rolling wheel assembly includes:

[0022] The roller seat is fixedly connected to the outer side of the belt and mounted on the side of the guide rail away from the bracket, and the chassis is fixedly installed on the side of the roller seat away from the guide rail.

[0023] At least two rollers are fixed to the roller seat on the side facing the guide rail, and the two rollers are spaced apart. The two rollers respectively make rolling contact with the inner side and the outer side of the guide rail.

[0024] According to this technical solution, two rolling wheels are respectively distributed on the inner and outer sides of the guide rail and roll in contact with the guide rail, reducing the friction when the rolling wheel assembly moves along the extension direction of the guide rail and ensuring the smoothness of the chassis conveying; in addition, the two rolling wheels clamp the guide rail, improving the stability of the conveying; the rolling wheel seat is used to fix the rolling wheels and the chassis, realizing the chassis to be set on one side of the outer surface of the belt, reducing the load on the belt and helping to improve the service life of the conveyor body.

[0025] In the optional technical solution of this utility model, the guide rail is a ring guide rail.

[0026] According to this technical solution, the circular guide rail allows the chassis of the conveyor body to be transported in a cyclical manner, eliminating the need to frequently start and stop the conveyor body when the chassis reaches the end of the guide rail, thus improving the convenience of operation.

[0027] In an optional technical solution of this utility model, a column is also fixed on the upper surface of the chassis;

[0028] The conveying mechanism also includes a transfer plate, with a through slot in the middle for the column to pass through. The positioning column is indirectly fixed to the chassis by being fixed to the transfer plate.

[0029] According to this technical solution, the chassis and the adapter plate are detachably connected via columns and through slots, which improves the convenience of replacement and installation.

[0030] In an optional technical solution of this utility model, multiple positioning posts are arranged separately in the circumferential direction of the chassis.

[0031] According to this technical solution, the positioning posts are arranged at intervals in the circumferential direction of the chassis, so that technicians do not need to reach into the middle of the chassis but only need to operate from the outer periphery of the chassis, which improves the convenience of operation.

[0032] In the optional technical solution of this utility model, a limiting component is also included, which is installed on the upper part of the sleeve to limit the radial direction of the workpiece.

[0033] According to this technical solution, radial positioning of the workpiece by limiting the workpiece helps to improve the positional stability of the workpiece during coating, thereby improving the coating quality.

[0034] In an optional technical solution of this utility model, the upper inner wall of the sleeve is formed with threads, and the limiting member is a nut, which is screwed between the inner side of the upper part of the sleeve and the outer periphery of the workpiece.

[0035] According to this technical solution, the radial positioning of the workpiece is achieved by using the threaded engagement between the nut and the inner wall of the sleeve. This simple and convenient method ensures the positional stability of the workpiece during coating, thereby improving the coating quality.

[0036] This utility model also provides a coating device, including the above-mentioned conveying mechanism. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a conveying mechanism, including: a conveyor body 1, a chassis 2, multiple positioning posts 3, and a sleeve 4 used in conjunction with the positioning posts 3. The conveyor body 1 is used to convey the workpiece A to be coated. The chassis 2 is provided with multiple positioning posts 3 along the conveying direction of the conveyor body 1 (the extension direction of the belt 15) and is respectively connected to the conveyor body 1. The multiple positioning posts 3 are directly or indirectly fixed to the upper surface of the chassis 2. The lower part of the sleeve 4 is hollow and is sleeved on the outside of the positioning posts 3. The upper part of the sleeve 4 is hollow and forms a workpiece slot 41 for the workpiece A to be inserted. The height of the workpiece slot 41 corresponds to the coating height of the part of the workpiece A that extends out of the workpiece slot 41.

[0047] In this embodiment, the height of the workpiece slot 41 is the same as the height to which workpiece A is inserted into the workpiece slot 41. The height of the workpiece slot 41 and the height of the portion of workpiece A extending out of the workpiece slot 41 to be coated together constitute the overall height of workpiece A. Here, "corresponding" means that the height of the workpiece slot 41 = the overall height of workpiece A - the height to be coated is satisfied. By selecting a sleeve 4 that matches the height to be coated of workpiece A (e.g., the height of sleeve 4 = the overall height of workpiece A - the height to be coated + the height of positioning post 3), the sleeve 4 is fitted onto the outside of positioning post 3. Workpiece A is inserted into the sleeve 4, and the height of workpiece A extending out of the upper part of the sleeve 4 is the coating height of workpiece A. Since the sleeve 4 is fitted onto the outside of positioning post 3, installation and removal are convenient. Only by selecting a sleeve 4 of appropriate height, workpieces A with different coating heights can be directly or indirectly loaded on the same chassis 2 or different chassis 2, satisfying different coating height requirements and the needs of batch coating.

[0048] Continue to refer to Figure 1 In a preferred embodiment of this utility model, the conveyor body 1 includes: a support 11, a drive mechanism 12, a drive wheel 13, a driven wheel 14, and a belt 15. The drive mechanism 12 is fixedly installed on the support 11. The drive wheel 13 is fixed to the drive mechanism 12 and installed above the support 11, with the axial direction of the drive wheel 13 being the same as the height direction of the support 11. The driven wheel 14 is disposed opposite to the drive wheel 13 on the support 11. The belt 15 is sleeved on the outside of the drive wheel 13 and the driven wheel 14. The drive mechanism 12 drives the drive wheel 13 to rotate and drives the belt 15 and the driven wheel 14 to rotate. The axial direction of the drive wheel 13 is the same as the height direction of the support 11, that is, the belt 15 is driven on the same plane (the horizontal plane above the support 11 in the figure). Using the above transportation method is beneficial to reduce the load on the belt 15 and improve the single transportation capacity and service life of the conveyor body 1.

[0049] like Figure 4As shown, in a preferred embodiment of this utility model, the chassis 2 is located on the side of the conveyor body 1 (here, "side" mainly refers to the four sides, excluding the bottom and top) and is separated from the conveyor body 1 by a predetermined distance. The conveying mechanism also includes: a guide rail 16, a roller assembly 17, and an adapter (not shown in the figure). The guide rail 16 is located on the outer periphery of the belt 15 and is fixed to the bracket 11; the roller assembly 17 is slidably connected to the guide rail 16, and the adapter is connected between the outer surface of the belt 15 (the outer surface of the belt 15 refers to the side surface of the belt 15 that does not contact the driving wheel 13 and / or the driven wheel 14) and the roller assembly 17. By setting the chassis 2 on one side of the outer surface of the belt 15 through the adapter, the load on the belt 15 is reduced, which is beneficial to improving the service life of the conveyor body 1 and improving the positional stability of the chassis 2. In this embodiment of the utility model, the structure of the adapter can be used to connect the belt 15 and the roller seat 171. The utility model does not limit this. For example, the adapter may include a first part and a second part that can be detachably connected. The first part is fixed to the belt 15 and the second part is fixed to the roller seat 171.

[0050] Continue to refer to Figure 4 The roller assembly 17 includes: a roller seat 171 and at least two rollers 172. The roller seat 171 is fixedly connected to the outer side of the belt 15 and is mounted on the side of the guide rail 16 away from the bracket 11. The chassis 2 is fixedly installed on the side of the roller seat 171 away from the guide rail 16. At least two rollers 172 are fixed to the side of the roller seat 171 facing the guide rail 16. The two rollers 172 are spaced apart and make rolling contact with the inner side and the outer side of the guide rail 16, respectively. In this embodiment, two rolling wheels 172 are respectively distributed on the inner and outer sides of the guide rail 16 and roll in contact with the guide rail 16, reducing the friction when the rolling wheel assembly 17 moves along the extension direction of the guide rail 16, ensuring the smoothness of the chassis 2's conveying; and the two rolling wheels 172 clamp the guide rail 16, improving the stability of the conveying; the rolling wheel seat 171 is used to fix the rolling wheels 172 and the chassis 2, realizing that the chassis 2 is set on one side of the outer surface of the belt 15, reducing the load on the belt 15, which is beneficial to improving the service life of the conveyor body 1. It should be noted that, in this embodiment, the inner side of the guide rail 16 refers to the side of the guide rail 16 facing or close to the belt 15, and the outer side of the guide rail 16 refers to the side of the guide rail 16 away from or away from the belt 15.

[0051] In this embodiment, there are four rollers 172, which are distributed on the four feet of the roller seat 171. In some embodiments, more rollers 172 may be provided according to the length of the roller seat 171 along the guide rail 16. Preferably, the rollers 172 are distributed in pairs on the inner and outer sides of the guide rail 16 to improve the stability of the conveying.

[0052] In a preferred embodiment of this invention, the guide rail 16 is an annular guide rail. The annular guide rail allows the chassis 2 conveyed by the conveyor body 1 to be transported cyclically, eliminating the need to frequently start and stop the conveyor body 1 when the chassis 2 reaches the end of the guide rail 16, thus improving the convenience of operation.

[0053] In the preferred embodiment of this utility model, such as Figure 1 , Figure 2 As shown, a column 21 is also fixed to the upper surface of the chassis 2; the conveying mechanism also includes a transfer plate 5, with a through groove 51 in the middle for the column 21 to pass through. The positioning column 3 is indirectly fixed to the chassis 2 by being fixed to the transfer plate 5. In this embodiment, the chassis 2 and the transfer plate 5 are detachably connected by the column 21 and the through groove 51, which improves the convenience of replacement and installation. In some embodiments, the through groove 51 can also be adjusted to a through hole, through which the column 21 can be inserted to position the transfer plate 5 on the chassis 2. In other embodiments, the chassis 2 and the transfer plate 5 can also be detachably connected by other means, such as snap-fit ​​or threaded connection. This utility model does not limit this.

[0054] In some embodiments, in order to increase the number of positioning posts 3 carried by a single chassis 2, the adapter plate 5 can be set as a double-layer structure, that is, it includes two adapter plates 5. The two adapter plates 5 are fixed together by a through groove 51. The through groove 51 can be sleeved on the outside of the column 21. The length of the through groove 51 should be such that it meets the sum of the length of the sleeve 4 on the positioning post 3 and the length of the workpiece A extending out of the sleeve 4, and a certain length allowance is reserved.

[0055] In the preferred embodiment of this utility model, such as Figure 5 As shown, multiple positioning posts 3 are arranged spaced apart in the circumferential direction of the chassis 2. This arrangement allows technicians to operate from the outer perimeter of the chassis 2 without needing to reach into its center, thus improving operational convenience. In some embodiments, the positioning posts 3 may not be distributed along the circumferential direction of the chassis 2, but rather in a longitudinal, transverse, or other configurations. Technicians can choose a suitable distribution method based on actual conditions, and this invention does not impose any limitations on this. Furthermore, the number of positioning posts 3 can be designed according to the dimensions of the chassis 2, and this invention does not impose any limitations on this.

[0056] In this embodiment of the invention, the chassis 2 is circular. In some embodiments, the chassis 2 may also be rectangular, elliptical or other shapes. This invention does not limit these shapes.

[0057] In a preferred embodiment of this invention, a limiting member (not shown in the figure) is further included, installed on the upper part of the sleeve 4 to radially limit the workpiece A. Radial limiting of workpiece A by the limiting member improves the positional stability of workpiece A during coating, thereby improving coating quality. In a preferred embodiment of this invention, the inner wall of the upper part of the sleeve 4 is threaded, and the limiting member is a nut, which is screwed between the inner side of the upper part of the sleeve 4 and the outer periphery of the workpiece A. The radial limiting of workpiece A is achieved by the threaded engagement of the nut and the inner wall of the sleeve 4, which simply and conveniently ensures the positional stability of workpiece A during coating, thereby improving coating quality.

[0058] In some embodiments, other support components may also be provided inside the sleeve 4, such as a sleeve structure with one end open and the other end closed. The closed end face provides support to ensure the stability of the support inside the sleeve 4 and the orientation of the workpiece A when it is installed in the sleeve 4, and to prevent the workpiece A from tilting inside the sleeve 4, which would affect the coating quality.

[0059] like Figure 6 As shown, another embodiment of this utility model provides a coating device, including the aforementioned conveying mechanism. The coating device also includes a manual cleaning mechanism 6, an automatic cleaning mechanism 7, a cooling mechanism 8, and a furnace mechanism 9. The specific structures of the manual cleaning mechanism 6, the automatic cleaning mechanism 7, the cooling mechanism 8, and the furnace mechanism 9 can be found in existing technology and will not be described in detail here. Furthermore, the coating device includes a shelf 10 for storing workpieces A of different specifications, sleeves 4, etc. Further, the shelf 10 is configured with a lifting function; when items need to be retrieved from the shelf 10, the shelf 10 rises or falls to a height suitable for workers to access the items. Preferably, the shelf 10 is arranged adjacent to the conveying mechanism to improve operational convenience. In addition, the coating device may also include a scanner, an operating interface, etc., so that scanning the specifications of workpiece A can output the corresponding sleeve specification information, facilitating workers to retrieve sleeves of the corresponding specifications for subsequent coating.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
