Technical Field
[0001] This utility model relates to the field of fan equipment technology, and in particular to an automatic feeding and assembly mechanism for fan motor bearings. Background Technology
[0002] Before the bearing is installed, the bearing needs to be press-fitted onto the shaft to axially limit and assist in the installation of the bearing. The end shaft of the motor rotor is usually provided with an annular groove.
[0003] The existing technology, CN2025100108739, describes a motor rotor snap ring assembly equipment. Existing feeding and assembly equipment all use vibratory feeders for feeding. This feeding method is costly, occupies a large area, and is not very practical when used in conjunction with a production line.
[0004] Therefore, it is necessary to design an automatic feeding and assembly mechanism for fan motor bearings to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an automatic feeding and assembly mechanism for wind turbine motor bearings, so as to overcome the above-mentioned shortcomings of the existing technology.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic feeding and assembly mechanism for fan motor bearings includes a carrier return mechanism, a feeding module disposed on one side of the carrier return mechanism, and a material handling and pressing module disposed on the other side of the carrier return mechanism and corresponding to the side of the feeding module. The feeding module includes a feeding mounting frame, a slide rail disposed on the feeding mounting frame, a storage mechanism slidably mounted on the slide rail via a slider, a drive motor connected to and driving the storage mechanism to move along the slide rail, a storage module disposed at the end of the slide rail and near the carrier return mechanism, and an arrangement unit disposed at the end of the storage module for pushing and arranging bearings. The storage mechanism includes a storage bracket, a dropping plate disposed between the storage brackets, and a material handling unit. The fixed plate is mounted on the blanking plate and the blanking shell is mounted on the blanking plate. The blanking shell is placed inside the blanking shell and is used to store the bearing. The blanking module includes a pusher mounting plate mounted on the loading mounting frame, a number of pusher slots mounted on the pusher mounting plate, a limit blanking block at the front end of each pusher slot, a pusher plate placed in the pusher slot, and a pusher cylinder that drives the pusher plate along the pusher slot. A blanking slot is opened on the limit blanking block and an avoidance slot is provided at the bottom of the limit blanking slot. The arrangement unit includes an arrangement slot mounted on the pusher mounting plate and connected to the pusher slot, a transverse module mounted at the front end of the pusher mounting plate, and an arrangement pusher block driven by the transverse module and placed on the arrangement slot.
[0008] Preferably, the bottom of the material discharge shell is fixed to the material discharge plate by a fixing plate, and the top is installed on the material storage bracket by a fixing member. The material discharge shell is configured to partially surround the bearing storage shaft. A material discharge groove is provided on the material discharge plate, and the bottom of the bearing storage shaft is placed in the material discharge groove. The diameter of the material discharge groove is larger than the diameter of the bearing.
[0009] Preferably, the arrangement groove is located at the front end of the pusher mounting plate, that is, near the end of the carrier return mechanism.
[0010] Preferably, the material handling and pressing module includes a material handling bracket, a movable module disposed on the material handling bracket and perpendicular to the carrier return mechanism, a material handling mounting plate driven by the movable module, a material handling module disposed on one side of the material handling mounting plate, and a pressing module disposed on the other side of the material handling mounting plate.
[0011] Preferably, the material handling module is located on the side close to the material loading module, and includes a material handling downward moving cylinder, a driving block driven by the material handling downward moving cylinder, a clamping cylinder 83 mounted on the driving block, and a clamping block driven by the clamping cylinder.
[0012] Preferably, the pressing module includes a pressing cylinder disposed on the material handling mounting plate and a pressing head driven by the pressing cylinder.
[0013] The beneficial effects of this utility model are as follows: This technical solution replaces the existing vibratory feeder module by setting up a material storage mechanism and a material storage module in combination. The material storage mechanism realizes the automatic falling of the bearing through a simple free fall structure. Then, the limiting material block of the material storage module limits the bearing and ensures that it falls accurately into the module. Finally, the pushing plate pushes the fallen material out to complete the discharge. The structure is simple, the cost is low, and it can be used with bearings of different diameters. In contrast, the existing vibratory feeder requires the replacement of the internal conveying mechanism or the entire structure to be used with bearings of different diameters.

[0019] Reference Figures 1 to 4 An automatic feeding and assembly mechanism for fan motor bearings includes a carrier return mechanism, a feeding module disposed on one side of the carrier return mechanism, and a material picking and pressing module disposed on the other side of the carrier return mechanism and corresponding to the side of the feeding module.
[0020] The feeding module includes a feeding mounting frame 1, a slide rail 2 mounted on the feeding mounting frame, a storage mechanism 3 slidably mounted on the slide rail via a slider, a drive motor connected to the storage mechanism and driving the storage mechanism to move along the slide rail, a storage module 4 located at the end of the slide rail and near the carrier return mechanism, and an arrangement unit 5 located at the end of the storage module for pushing and arranging bearings.
[0021] The material storage mechanism includes a material storage bracket 31, a material drop plate 32 disposed between the material storage brackets, a material drop shell 33 mounted on the material drop plate via a fixing plate, and a bearing storage shaft 34 placed inside the material drop shell for storing bearings. The bottom of the material drop shell is fixed to the material drop plate via a fixing plate, and the top is mounted on the material storage bracket via a fixing member. The material drop shell partially surrounds the bearing storage shaft, which is used to accommodate bearing installation. Bearings are sleeved on the bearing storage shaft, and bearings are stacked on the bearing storage shaft. A material drop groove 35 is provided on the material drop plate, and the bottom of the bearing storage shaft is placed in the material drop groove. The diameter of the material drop groove is larger than the diameter of the bearing to allow the bearing to enter.
[0022] In the implementation case, several sets of bearing storage shafts are set on the blanking plate, and each set of bearing storage shafts corresponds to a set of blanking grooves and blanking shells. The bearings are put on the bearing storage shafts manually or by machine. The blanking shells are semi-enclosed to the bearing storage shafts, which limit the bearings installed on the bearing storage shafts to ensure that they do not move and can fall accurately into the blanking grooves.
[0023] The material storage module 4 includes a pusher mounting plate 41 mounted on the feeding mounting frame, several sets of push slots 42 mounted on the pusher mounting plate, a limiting drop block 43 at the front end of each set of push slots, a pusher plate 44 placed in the push slot, and a pusher cylinder 45 that drives the pusher plate along the push slot. In order to cooperate with the material storage mechanism and ensure that the bearing can fall accurately into the limiting drop block, a material storage slot 46 is provided on the limiting drop block, and a clearance slot 47 is provided at the bottom of the limiting drop slot. The clearance slot is used to cooperate with the pusher plate for the pusher plate to move. The pusher plate is located at the rear end of the pusher mounting plate.
[0024] In this implementation process, each set of pusher troughs corresponds to a set of bearing storage shafts, and the limiting drop block of each set of pusher troughs corresponds one-to-one with a set of bearing storage shafts. The bearing storage shaft is driven to move onto the limiting drop block, and the drop groove on the drop plate is vertically aligned with the storage groove of the limiting drop block. The bearing sleeved on the bearing storage shaft automatically moves down along the bearing storage shaft and falls into the storage groove of the limiting drop block, and is placed in the pusher trough. The pusher cylinder drives the pusher plate to move along the pusher trough, pushing the bearing placed in the pusher trough out and placing it on the work station of the arrangement unit. Only one set is pushed out at a time. If multiple sets are set, each set will push in a cyclical manner to prevent excessive pushing and material accumulation.
[0025] The arrangement unit 5 includes an arrangement slot 51 disposed on the pusher mounting plate and connected to the pusher groove, a transverse moving module 52 disposed at the front end of the pusher mounting plate, and an arrangement pushing block 53 driven by the transverse moving module and placed on the arrangement slot.
[0026] The arrangement slot is located at the front end of the pusher mounting plate, that is, near the end of the carrier return mechanism; after the specific bearing is pushed out by the storage module, it moves into the arrangement slot, and the lateral movement module drives the arrangement push block to move along the arrangement slot, and pushes the bearing placed on the arrangement slot to the end of the arrangement slot for the material picking and pressing module to pick up and press into the fan motor.
[0027] The material handling and pressing module includes a material handling bracket, a moving module 6 disposed on the material handling bracket and perpendicular to the carrier return mechanism, a material handling mounting plate 7 driven by the moving module, a material handling module 8 disposed on one side of the material handling mounting plate, and a pressing module 9 disposed on the other side of the material handling mounting plate.
[0028] The material handling module 8 is located on one side close to the material loading module, and includes a material handling and lowering cylinder 81, a driving block 82 driven by the material handling and lowering cylinder, a clamping cylinder 83 mounted on the driving block, and a clamping block 84 driven by the clamping cylinder.
[0029] The pressing module 9 includes a pressing cylinder 91 disposed on the material taking mounting plate and a pressing head 92 driven by the pressing cylinder;
[0030] The moving module drives the material handling module to move to the top of the end of the arranging slot (i.e., the end where the arranging push block pushes the bearing). The material handling downward movement cylinder drives the clamping block to move down and place it on the inner ring of the bearing. The clamping cylinder drives the outer support to support and fix the bearing. After resetting and moving upward, it moves to the tooling of the carrier return mechanism. Then it moves downward to place the bearing in the corresponding position of the fan motor. The clamping cylinder is then released, and the bearing is placed inside the fan motor. The material handling is completed. Then it moves upward and resets. The moving module drives the pressing mechanism to move above the bearing installation position on the fan motor. The pressing cylinder drives the pressing head to press down and press the bearing into the fan motor, completing the bearing pressing. Then it moves upward and resets, repeating the material handling and pressing process.
[0031] The process in this implementation case is as follows: The bearing, which is sleeved on the bearing storage shaft, automatically moves down along the bearing storage shaft and falls into the storage groove of the limiting material dropping block, and is placed in the pushing groove. The pushing cylinder drives the pushing plate to move along the pushing groove, pushing the bearing placed in the pushing groove out and into the arranging groove. The transverse module drives the arranging pushing block to move along the arranging groove, pushing the bearing placed in the arranging groove to the end of the arranging groove to await the material pressing module to work. The moving module drives the material picking module to move to the end above the arranging groove (i.e., the end where the arranging pushing block pushes the bearing to rest), and the material picking and lowering cylinder... The drive moves the clamping block downwards, placing it on the inner ring of the bearing. The clamping cylinder drives the outer support, thus holding and fixing the bearing in place. After resetting, it moves upwards and then back to the tooling of the carrier return mechanism. It then moves downwards, placing the bearing in the corresponding position on the fan motor. The clamping cylinder then releases, placing the bearing inside the fan motor. This completes the loading process. The module then moves upwards and resets, driving the pressing mechanism to move above the bearing mounting position on the fan motor. The pressing cylinder drives the pressing head downwards, pressing the bearing into the fan motor, completing the bearing pressing. The module then moves upwards and resets, repeating the loading and pressing process.
[0032] The advantages of this utility model are that this technical solution replaces the existing vibratory feeder module by setting up a material storage mechanism and a material storage module. The material storage mechanism realizes the automatic falling of the bearing through a simple free-fall structure. Then, the limiting block of the material storage module limits the bearing and ensures that it falls accurately into the module. Finally, the pushing plate pushes the fallen material out to complete the discharge. The structure is simple, the cost is low, and it can be used with bearings of different diameters. In contrast, the existing vibratory feeder requires the replacement of the internal conveying mechanism or the entire structure to be used with bearings of different diameters.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
