Description

Technical Field

[0001] The utility model relates to the technical field of motor production, in particular to a workstation transfer device. Background Art

[0002] The motor production process requires multiple steps, and the finished product is usually obtained through assembly line processing. As an important component of the motor, the motor stator needs to be transported multiple times during the mass production process.

[0003] Chinese patent publication number CN215625056U proposes "a stator core transfer system". This technical solution addresses the problem that "previous motor production has been done manually, which is labor-intensive and inefficient. The use of assembly line operations can effectively improve production efficiency." The utility model provides the following technical solution: "A grabbing robot, arranged on the first track, can move along the first track, and is used to grab the stator core on the first unloading end and place it on the stator core placement rack, and can transfer the stator core to be processed to each processing station."

[0004] The above scheme has the following defects: the stator core is heavy, and the manipulator will inevitably slip and fall when grabbing the stator core and moving it. Once the stator core collides with the ground, its outer surface will be damaged. Therefore, a workstation transfer device is proposed to solve the above problem. Utility Model Content

[0007] The lossless transfer mechanism includes a No. 1 conveyor belt installed on the surface of the mounting plate, two supporting side plates fixedly installed on the surface of the mounting plate, and a longitudinal transfer mechanism located between the two supporting side plates.

[0008] The longitudinal transfer mechanism includes an AC motor fixedly installed on the top of the supporting side plate, a driving screw fixedly installed on the output end of the AC motor, a support plate threadedly installed on the outside of the driving screw, two stainless steel rods fixedly installed between the two supporting side plates, and a material moving mechanism located on the surface of the support plate.

[0010] Furthermore, the defective product sorting mechanism includes a No. 3 conveyor belt fixedly installed on the surface of the mounting plate, two skeletons fixedly installed on the surface of the mounting plate, and two visual inspection probes fixedly installed inside the skeletons.

[0011] The beneficial effect of adopting the above further solution is that unqualified workpieces in transit can be sorted out by the defective product sorting mechanism.

[0012] Furthermore, the conveying direction of the No. 1 conveyor belt is toward the left, and the supporting side plate is located on the left side of the No. 1 conveyor belt.

[0013] The beneficial effect of adopting the above further solution is that the workpiece is conveyed to the left by the No. 1 conveyor belt, and the two supporting side plates play a supporting role.

[0014] Furthermore, the output end of the AC motor faces downward, and the driving screw is rotatably installed between two supporting side plates.

[0015] The beneficial effect of adopting the above further solution is that the screw rod is driven by the AC motor to rotate forward and reverse between the two supporting side plates.

[0016] Furthermore, the support plate is located on the left side of the No. 1 conveyor belt, and the interval between the support plate and the No. 1 conveyor belt is no more than one centimeter.

[0018] Furthermore, the two stainless steel rods both penetrate into the interior of the support plate, and the support plate slides up and down outside the two stainless steel rods.

[0019] The beneficial effect of adopting the above further solution is that the support plate is supported by two stainless steel rods to slide up and down between the two supporting side plates, and the automatic movement of the support plate can be achieved by driving the screw rod to rotate forward and reverse.

[0020] Furthermore, the two linear modules are respectively located near the top and bottom ends of the pallet, the output shafts of the two servo motors respectively penetrate the right sides of the two movable plates, the two pull plates are both located near the left end of the No. 1 conveyor belt, and the No. 2 conveyor belt is located on the left side of the stainless steel rod.

[0021] The beneficial effect of adopting the above further scheme is that by driving the two movable plates through the linear module, the two pull plates can be driven to move left and right on the surface of the pallet, thereby facilitating the removal of the workpiece on the surface of the pallet. The two servo motors respectively drive the two pull plates to rotate outward to prevent the pull plates from blocking the workpiece transported to the surface of the pallet by the No. 1 conveyor belt, and the workpiece can be transported to the next work station through the No. 2 conveyor belt.

The two visual inspection probes detect the condition of the workpieces on the surface of the pallet and transmit the signals to the two linear modules. Then the two linear modules can drive the two movable plates and the pull plate to move to the left, thereby moving the workpieces on the surface of the pallet to the surface of the No. 3 conveyor belt.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This workstation transfer device transfers the workpiece to the surface of the pallet via conveyor belt No. 1, and then two visual inspection probes detect the integrity of the workpiece on the surface of the pallet. After detecting the problematic workpiece, the two linear modules drive the two pull plates to move to the left to transfer the workpiece on the surface of the pallet to the surface of conveyor belt No. 3 to be transmitted to the outside world. When the workpiece is fine, the AC motor drives the pallet and the workpiece to move to the right side of conveyor belt No. 2, and then the two linear modules drive the two pull plates to move to the left to transfer the good workpiece to the surface of conveyor belt No. 2 and transport it to the next workstation. This device does not require a clamping mechanism when transferring the workpiece, thereby achieving the effect of reducing the risk of damage to the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
