Description

Technical Field

[0001] This utility model relates to the field of commutator manufacturing equipment, specifically to an anti-slip commutator conveying device. Background Technology

[0002] Commutators are key components in DC motors and some AC motors (such as series motors). They are mainly used to achieve periodic switching of current direction to ensure continuous motor rotation.

[0003] In current production processes, commutators are generally manufactured using automated equipment. After the commutator is manufactured, some post-processing and testing are required, such as surface treatment and grinding of the carbon brush contact surface to form an arc surface that matches the commutator, thereby reducing running friction. Before grinding, the commutator is transported to the grinding table by a conveyor belt. During this process, because the commutator is equipped with copper claws, the copper claws between two adjacent commutators may get caught, causing the commutator to fall off the conveyor belt as it moves to the processing track, resulting in damage to the copper claws. Therefore, a conveyor device that can prevent slippage is needed to solve this problem. Utility Model Content

[0004] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0005] A commutator conveying device for preventing slippage includes a conveyor belt, a push rod, a sensor, a processing track, a limiting device A, and a limiting device B. The conveyor belt is perpendicular to the processing track. Anti-slip guide rails are provided on both sides of the conveyor belt and the processing track. The push rod is located at one end of the processing track. The limiting devices A and B are respectively installed on the anti-slip guide rails on one side of the conveyor belt. Two grooves are provided on the anti-slip guide rails. The front ends of the limiting devices A and B are connected to stop bars, and the two stop bars are respectively located in the two grooves. The sensor is installed on the anti-slip guide rails and located on one side of the conveyor belt.

[0006] Preferably, the sensor is located between the two grooves.

[0007] Preferably, the front end of the push rod has an arc-shaped structure.

[0008] Preferably, the front end of the stop bar has a frustum-shaped structure that is smaller at the front and larger at the back.

[0009] Preferably, the front end of the stop bar is stretched to the middle position of the conveyor belt.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting two limit devices to limit the feeding speed and accuracy of the commutator, the problem of material falling off when the commutator is pushed by the push rod during the conveying process can be reduced due to the commutator's own copper claw structure. This avoids damage to the copper claw and affects the working quality and efficiency of the commutator.

[0012] 2. By setting the front end of the push rod to an arc shape, it can better fit the structure of the commutator and minimize damage to the copper claw during the pushing process.

[0013] 3. By setting a frustum structure with different sizes at the front and back of the baffle, it is possible to prevent the conical structure from getting caught on the copper claws on the commutator 8, and it can also block the subsequent commutators. Attached Figure Description

[0021] Example 1

[0022] Reference Figure 1 A commutator conveying device for preventing slippage includes a conveyor belt 1, a push rod 2, a sensor 3, a processing track 4, a limiting device A5-1, and a limiting device B5-2. The conveyor belt 1 is perpendicular to the processing track 4. Anti-slip guide rails 6 are provided on both sides of the conveyor belt 1 and the processing track 4. The push rod 2 is located at one end of the processing track 4. The limiting devices A5-1 and B5-2 are respectively installed on the anti-slip guide rail 6 on one side of the conveyor belt 1. Two grooves 6-1 are provided on the anti-slip guide rail 6. The front ends of the limiting devices A5-1 and B5-2 are connected to the stop rods 7, and the two stop rods 7 are respectively located in the two grooves 6-1. The sensor 3 is installed on the anti-slip guide rail 6 and is located on one side of the conveyor belt 1.

[0023] Preferably, the sensor 3 is located between the two recesses 6-1.

[0024] In actual operation, sensor 3, limit device A5-1 and limit device B5-2 are all connected to the control module in the commutator production process. Sensor 3 can transmit data to the control module, and the control module will send instructions to limit device A4 and limit device B5 according to the received signals, thereby controlling their extension and retraction movements.

[0025] During the production process, when the commutator 8 enters the conveyor belt 1 for conveying, the limiting device A5-1 is in the extended state and the limiting device B5-2 is in the retracted state. At this time, the stop bar 7 at the front end of the limiting device A5-1 will block the commutator 8 that is about to enter the processing track 4. After the previous commutator finishes processing, the stop bar 7 at the front end of the limiting device A5-1 will retract, and the commutator 8 will move forward with the conveyor belt 1. When the previous commutator 8 enters the processing track 4, the next commutator 8 moves exactly in front of the sensor 3. At this time, the sensor 3 transmits a signal to the control module, and then the control module controls the limiting device A5-1 to extend and the limiting device B5-2 to retract according to the received signal, blocking the next commutator 8. The push rod 2 will also push the commutator 8 on the processing track 4 toward the grinding worktable.

[0026] Using this conveying device to transport commutators makes the conveying process of commutators more stable and avoids the problem of commutator 8 falling off when pushed by the push rod due to its own copper claw structure during the conveying process of multiple commutators. This avoids damage to the copper claws and affects the working quality and efficiency of the commutator.

[0027] Example 2

[0028] Reference Figure 2 The difference between this embodiment and embodiment one is that the front end of push rod 2 is an arc-shaped structure. By setting the front end of push rod 2 to an arc-shaped structure, it can better fit the structure of the commutator and minimize damage to the copper claw during the pushing process.

[0029] Example 3

[0030] Reference Figure 3 The front end of the baffle 7 is a frustum-shaped structure that is smaller at the front and larger at the back. The front end of the baffle 7 can be stretched to the middle of the conveyor belt 1. By setting the front and rear frustum-shaped structure of the baffle 7, it can prevent the conical structure from getting caught on the copper claws on the commutator 8, and at the same time, it can also block the subsequent commutator 8.
