Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a motor bearing assembly mechanism. Background Technology

[0002] During the assembly of a motor, bearings need to be installed on the motor stator. For bearing loading, a batch of bearings is usually placed in a vibratory feeder, which then transports the bearings one by one to a connected conveyor belt. A robotic arm then picks up the bearings on the conveyor belt for subsequent assembly. However, when loading bearings using a vibratory feeder, it is difficult to control the precise position of the bearings on the conveyor belt. Moreover, during conveying on the conveyor belt, due to the small weight of the bearings and the vibration of the conveyor belt, the position of the bearings on the conveyor belt is even more difficult to control, resulting in low positional accuracy of the bearings and affecting the normal gripping of the robotic arm. Therefore, it is necessary to develop a motor bearing assembly mechanism to solve the above problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1 to 3As shown, a motor bearing assembly mechanism includes a bearing feeding device 1, a bearing handling robot 2, and an assembly platform 3. The bearing feeding device 1 includes a base 11, a bearing hopper 12, a conveying assembly 13, a positioning assembly 14, a first pushing assembly 15, and a second pushing assembly 16. A pushing groove 111 and a dropping groove 112 are respectively provided on the left and right sides above the base 11. The bearing hopper 12 is fixed to the base 11, and its discharge end corresponds to the top of the dropping groove 112. The conveying assembly 13 is fixed to the front side of the base 11, and a conveyor belt 132 is provided on the conveying assembly 13. The conveying end of the conveyor belt 132 corresponds to the front side of the dropping groove 112 and the front side of the pushing groove 111. The positioning assembly 14 is fixed to the base 11. The component 14 is provided with an upward-opening guide groove 141 and a positioning groove 142. The rear end of the positioning groove 142 is connected to the pusher groove 111, and the left end of the guide groove 141 is connected to the rear end of the positioning groove 142. The conveyor belt 132 passes through the rear ends of the guide groove 141 and the positioning groove 142. The first pusher component 15 is fixed to the rear end of the base 11 and corresponds to the drop groove 112. It is used to push the bearing on the drop groove 112 to the conveyor component 13. The second pusher component 16 is fixed to the rear end of the base 11 and corresponds to the pusher groove 111. It is used to push the bearing from the rear end of the positioning groove 142 to the front end. The assembly platform 3 is fixedly set on one side of the bearing loading device 1. The bearing handling robot 2 is mounted above the bearing loading device 1 and the assembly platform 3.

[0021] The bearings to be loaded are placed in the bearing hopper 12. The bearings at the bottom of the hopper fall into the discharge chute 112. The first pushing component 15 pushes the bearings in the discharge chute 112 forward onto the conveyor belt 132. The conveying component 13 transports the bearings to the left via the conveyor belt 132. After passing through the guide groove 141, the bearings enter the rear end of the positioning groove 142. Then, the second pushing component 16 pushes the bearings to the front end of the positioning groove 142, thereby accurately positioning the bearings. Subsequently, the bearing handling robot 2 transports the bearings to the assembly platform 3 for assembly with the stator components of the motor. The advantages of this design are: it can stably transport the bearings and place them in a precise position at the front end of the positioning groove 142, which facilitates the material handling robot 2 to pick up the bearings, and also improves the accuracy and stability of the assembly of the bearings and stator components.

[0022] The bearing hopper 12 includes a discharge base plate 121, a storage pipe 122, a mounting frame 123, a tapping cylinder 124, and a tapping rod 125. The discharge base plate 121 is fixed on the base 11 and corresponds to the upper part of the discharge trough 112. Multiple sets of material placement troughs 1211 are provided below the discharge base plate 121. Mounting holes 1212 communicating with the material placement troughs 1211 are provided above the discharge base plate 121. The storage pipe 122 is vertically arranged and its lower end is fixed in the mounting hole 1212. The mounting frame 123 is fixed above the discharge base plate 121. The tapping cylinder 124 is fixed on the mounting frame 123. Multiple sets of storage pipes 122 are provided and correspond one-to-one with the material placement troughs 1211. The tapping rod 125 is fixed at the power output end of the tapping cylinder 124 and corresponds to the front side of all storage pipes 122.

[0023] The bearings are stacked inside the storage tube 122. The lower end of the storage tube 122 can be easily disassembled from the mounting hole 1212 on the bottom plate 121 to replace the empty storage tube 122. The bearing at the bottom of the storage tube 122 falls on the discharge trough 112 and corresponds to the placement trough 1211. Due to the height limitation of the placement trough 1211, only one set of bearings is allowed to fall into the placement trough 1211 at a time to avoid bearing overlap. The tapping cylinder 124 drives the tapping rod 125 to tap the outside of the storage tube 122 at a certain period of time, thereby making the bearing fall smoothly through vibration and preventing the bearing from getting stuck in the storage tube 122.

[0024] The first feeding assembly 15 includes a first connecting frame 151, a first cylinder 152, and a first pushing block 153. The first connecting frame 151 is fixed on the base 11, the first cylinder 152 is fixed above the first connecting frame 151, and the first pushing block 153 is fixed at the power output end of the first cylinder 152. The front end of the first pushing block 153 is provided with multiple sets of first pushing rods 1531, and the multiple sets of first pushing rods 1531 correspond one-to-one with multiple sets of feeding slots 1211.

[0025] The first cylinder 152 drives the first push block 153 to move forward, thereby causing the first push rod 1531 to push the bearing forward in the material trough 1211, so that the bearing is pushed onto the conveyor belt 132. The storage pipe 122 is arranged in multiple sets at intervals, so that multiple sets of bearings are pushed together, and there is a certain distance between the multiple sets of bearings to avoid the bearings from being too close to each other and colliding, thereby affecting the conveying accuracy.

[0026] The conveying assembly 13 includes a rotary drive assembly 131, a support base 133, a limiting plate 134, and a conveyor belt 132. The rotary drive assembly 131 is fixed on the base 11, and the conveyor belt 132 is fixed on the power output end of the rotary drive assembly 131. The support base 133 is fixed on the base 11 and corresponds to the front side of the material drop chute 112. The conveyor belt 132 passes through the upper rear side of the support base 133. The upper front side of the support base 133 is provided with an upwardly protruding limiting boss 1331. The front end of the limiting plate 134 is fixed to the upper end of the limiting boss 1331, and the rear end of the limiting plate 134 corresponds to the upper part of the conveyor belt 132.

[0027] The rotary drive assembly 131 drives the conveyor belt 132 to rotate. The conveyor belt 132 passes over the support seat 133 and conveys the bearing pushed onto the conveyor belt 132. When the first pusher assembly 15 pushes the bearing, the limiting boss 1331 can limit the pushing position of the bearing, while the limiting plate 134 can further prevent the bearing from overlapping or popping out.

[0028] The second pusher assembly 16 includes a second connecting frame 161, a second cylinder 162, and a second pusher block 163. The second connecting frame 161 is fixed on the base 11, the second cylinder 162 is fixed above the second connecting frame 161, and the second pusher block 163 is fixed at the power output end of the second cylinder 162. The front end of the second pusher block 163 is provided with a second push rod 1631, which passes through the pusher groove 111 and has an arc-shaped groove 16311 at its front end.

[0029] The second cylinder 162 drives the second push block 163 to move forward, thereby pushing the bearing forward to the front end of the positioning groove 142 by the second push rod 1631. At the same time, the side of the second push rod 1631 prevents subsequent bearings from entering the positioning groove 142. The arc-shaped groove 16311 at the front end of the second push rod 1631 matches the side wall of the bearing, which makes it easy for the second push rod 1631 to push the bearing forward accurately and stably.

[0030] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
