Description

Technical Field

[0001] The utility model relates to the technical field of stator processing, in particular to a mold driving device. Background Art

[0002] Stator processing includes paper inserting, wire winding and wire embedding processes. In the prior art, multiple stator wire embedding molds are generally transported by conveying mechanisms such as synchronous belts. When the stator wire embedding mold is transported to the paper inserting station, the paper inserting action is performed. When the stator wire embedding mold is transported to the winding station, the winding action is performed. When the stator wire embedding mold is transported to the wire embedding station, the stator core is embedded with wire and paper is pushed.

[0003] Among them, multiple stator wire embedding molds are driven by synchronous belts, that is, multiple stator wire embedding molds move synchronously, but the processing time at each processing station is different. For example, when three stator wire embedding molds are respectively transported to the paper insertion station, the winding station and the wire embedding station, the winding action takes a long time, resulting in the stator wire embedding molds in other stations having to wait until the winding is completed before they can continue to be transported together, which will affect the overall processing rhythm and production efficiency.

[0037] like Figure 1-8As shown, this embodiment provides a mold driving device for driving the stator wire inserting mold to flow and move between various stations on the mold conveyor line 3, and the mold driving device includes a clutch connection block 112, a first driving unit 11 and a second driving unit 12, wherein the first driving unit 11 is connected to a first driving plate 111, the clutch connection block 112 is arranged on the first driving plate 111, and a clutch connection groove 211 is correspondingly arranged on the mold 2, the first driving unit 11 can drive the clutch connection block 112 to extend and cooperate with the clutch connection groove 211, and the second driving unit 11 is connected to the first driving plate 111. The element 12 is connected to the second driving plate 121, and the first driving unit 11 is installed on the second driving plate 121. At this time, the second driving unit 12 can drive the first driving unit 11 and the mold 2 to move along the mold conveying line 3; the first driving unit 11 can also drive the clutch connecting block 112 to retract and disengage from the docking with the clutch connecting groove 211. At this time, the second driving unit 12 only drives the first driving unit 11 to move when it moves, and will not drive the mold 2 to move. The second driving unit 12 can drive the first driving unit 11 to move to dock with other molds 2 on the mold conveying line 3.

[0038] In this way, the mold driving device provided in this embodiment, when the mold 2 needs to move, firstly drives the clutch connection block 112 to dock with the mold 2 through the first driving unit 11, and then drives the mold 2 to the corresponding station through the second driving unit 12, and then the first driving unit 11 can drive the clutch connection block 112 to disengage from the docking with the mold 2, and the second driving unit 12 can drive other molds 2 to move, so that multiple stations with longer processing time can be set, for example, corresponding to one wire embedding station 43, multiple winding stations 42 are set at the same time, for example, six, or the winding station 42 is set as a multi-head winding machine that can perform multiple winding actions at the same time, for example, a six-head winding machine, when the wire embedding station 43 is completed for multiple times in sequence, the multiple winding actions performed at the same time are also completed, so that the processing beat can be guaranteed and the production efficiency can be improved. In the prior art, the synchronous belt is used to transport the mold 2. Even if multiple stations with longer processing time are set, it is impossible to achieve sequential transportation in the wire embedding station 43, and the above-mentioned technical effect of this embodiment cannot be achieved.

[0039] In order to better achieve the clutch of the mold 2 and the first drive unit 11, the present embodiment is provided with an arc-shaped guide portion 2111 at the connection end of the clutch connection groove 211, the clutch connection groove 211 is a U-shaped groove, the arc-shaped guide portion 2111 is formed at the two edges of the opening of the U-shaped groove, and the clutch connection block 112 is preferably a horizontally rotatable bearing. In this way, during docking, the mold 2 can be more easily and accurately docked with the clutch connection block 112 through the guidance of the arc-shaped guide portion 2111, and the clutch connection block 112 is a bearing, which is in rolling contact with the arc-shaped guide portion 2111, which can reduce the friction during docking.

[0040] In this embodiment, the first drive unit 11 is preferably a cylinder 442, and the second drive unit 12 is preferably a linear motor mover. A linear motor stator 31 is correspondingly provided on the mold conveyor line 3, and a grating ruler can also be provided to determine the displacement. In other embodiments, the first drive unit 11 can also be an electric push rod, a screw rod, etc., and the second drive unit 12 can also be a gear rack mechanism, etc.

[0041] In order to better realize the sliding of the mold 2 and the second drive unit 12, the present embodiment is provided with a first guide rail 32 and a second guide rail 33 on the mold conveyor line 3, wherein the first guide rail 32 is used to cooperate with the first slider 212 provided on the mold 2 to realize sliding, and the number of the first guide rail 32 can be set according to the size of the mold 2, such as preferably two in the present embodiment; the second guide rail 33 is used to cooperate with the second slider 122 provided on the second drive unit 12 to realize sliding.

[0042] The second drive unit 12, the first drive unit 11 and the mold 2 can be set in a one-to-one correspondence, that is, one first drive unit 11 is connected to one mold 2, and one second drive unit 12 drives one first drive unit 11 and one mold 2 to move. This correspondence is suitable for a single workstation with a short processing time. According to the processing rhythm, at different workstations, for example, for a workstation with a long processing time, it is set to multiple, and for this, a second drive unit 12 can be set to drive one first drive unit 11 to move, and one first drive unit 11 can drive multiple clutch connection blocks 112 to move together; or, a second drive unit 12 can be set to drive multiple first drive units 11 to move, and one first drive unit 11 can drive one clutch connection block 112 to move; or, a second drive unit 12 can be set to drive multiple first drive units 11 to move, and one first drive unit 11 can drive multiple clutch connection blocks 112 to move.

[0043] In order to ensure that each mold 2 can be processed stably at each station, the present embodiment further provides a positioning groove 213 on the mold 2. When the mold 2 is transported to each processing station, the positioning device 44 extends a positioning block 441 to cooperate with the positioning groove 213 for positioning. Specifically, the positioning groove 213 is preferably a U-shaped groove, that is, the structure is the same as the clutch connection groove 211, such as Figure 7 As shown, the positioning device 44 includes a cylinder 442 and a positioning block 441. The positioning block 441 is also preferably a bearing. The cylinder 442 horizontally pushes the positioning block 441 to move directly toward the positioning groove 213, or as shown in FIG. Figure 8As shown, the positioning device 44 includes a cylinder 442, a connecting rod assembly 443 and a positioning block 441. The cylinder 442 vertically pushes the connecting rod assembly 443, which converts the force into a horizontal force and then pushes the positioning block 441. This method is suitable for situations where the horizontal space is limited.

[0044] The workstations of this embodiment include processing stations such as a paper inserting station 41, a winding station 42 and a wire embedding station 43, and also include waiting stations. For example, before winding, multiple molds 2 need to be pre-stored and then transported to the winding station 42. For example, after winding, multiple molds 2 need to be transported to the wire embedding station 43 in sequence. In these processes, it is necessary to set up temporary fixed waiting stations. Specifically, a limiting structure for temporarily fixing the mold 2 is also provided on the side of the clutch connection groove 211 on the mold 2. The limiting structure includes a limiting pin 214 that can be vertically deflected and hinged. A limiting seat 34 is provided on the mold conveying line 3 corresponding to each waiting station. When the mold 2 is located at the waiting station, the limiting pin 214 is clamped into the limiting seat 34 at its second end under the action of the elastic member 215, so that the mold 2 cannot move along the mold conveying line 3. The elastic member 215 can be set on the limiting pin. A spring between the first end of the first drive plate 111 and the mold 2; a push block 113 is also connected to the first drive plate 111 at the output end of the first drive unit 11, and the push block 113 is located on the side of the clutch connection block 112. When the first drive unit 11 drives the clutch connection block 112 to dock with the clutch connection groove 211, the push block 113 also pushes the first end of the limit pin 214 accordingly, and the limit pin 214 deflects so that its second end is out of the limit of the limit seat 34, so that the mold 2 can move along the mold conveyor line 3. Since the aforementioned positioning device 44 exists at the processing station, the limit seat 34 can be omitted at each processing station.

[0045] Furthermore, the mold 2 includes a mold moving plate 21 and a mold head 22, the clutch connecting groove 211, the positioning groove 213 and the limiting structure are arranged on the mold moving plate 21, and in addition, an elastically retractable rotation limiting pin 216 is also provided on the mold moving plate 21, and a rotation limiting groove 221 is correspondingly provided on the mold head 22. When other workstations do not require winding, the rotation limiting pin 216 is correspondingly inserted into the rotation limiting groove 221 to prevent the mold head 22 from rotating. At the winding workstation 42, the rotation limiting pin 216 can be pulled back to release the limit on the mold head 22, and the mold head 22 can be indexed at this time.

[0046] The mold conveyor line 3 of this embodiment is preferably a circular conveyor line, which can be square, circular or track-shaped, and the mold driving device is set according to the processing rhythm, so that the mold can be asynchronously moved when it flows between each station. In this embodiment, it is preferably square, with two paper punching stations, a winding station 42, which is a six-head winding machine, and a wire inserting station 43. Multiple molds 2 flow between these stations. Specifically, on the first long side, the mold 2 is Figure 2 The individual clutch connection blocks 112 shown are transported to the paper punching station one by one in sequence, and after the paper punching is completed, they are transported to the rear waiting station for storage; after six are stored, they are moved together by the translation mechanism to the first short side; then on the other long side, by Figure 6 The six clutch connection blocks 112 shown in the figure transport the six molds 2 to the winding station 42, and after the winding is completed, Figure 6 The six clutch connection blocks 112 shown transport the six molds 2 to the wire embedding station 43 for wire embedding and paper pushing in sequence; after the wire embedding and paper pushing are completed, the mold 2 is moved to another short side through the parallel mechanism to form a cycle.

[0047] In this embodiment, a product conveyor line is further provided on the outer side of the mold conveyor line 3. The product conveyor line is used to convey products, and the product is a stator. The unprocessed product, i.e., the stator core, is placed on the last station, i.e., the wire embedding station 43, of the mold conveyor line 3 for processing through the pick-and-place module 35, and the processed product, i.e., the stator core with paper insertion and wire embedding, is placed back on the product conveyor line for further conveyance through the pick-and-place module 35. The pick-and-place module 35 and the product conveyor line are arranged close to the wire embedding station 43.

[0048] It can be seen from the above content that the mold driving device provided in this embodiment can drive one or more molds to move on the mold conveyor line according to needs, thereby ensuring the production rhythm and improving processing efficiency.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
