Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, and in particular relates to a stator sheet transfer device for a motor. Background Art

[0002] The stator is the stationary part of the motor. It consists of three parts: the stator core, stator windings, and the frame. The stator's primary function is to generate a rotating magnetic field, while the rotor's primary function is to generate (or output) current by being cut by magnetic lines of force within the rotating field. During stator production, the stator is typically stamped from silicon steel sheets using a stamping process. The stator sheets are then stacked and bonded together using adhesive to form the stator.

[0003] In the existing stator assembly process, glue is evenly applied to the surface of the stator segments using a glue dispenser. The segments are then placed under a press to press the stacked segments together. This process is often performed manually, which is inefficient and affects assembly efficiency. Furthermore, manual placement of the segments can lead to operational deviations, making it easy for the slots of adjacent segments to misalign, impacting the quality of the finished stator.

[0035] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0036] like Figure 2 Figure 2 shows the structure of the stator segment transfer device for a motor according to the present invention. It includes a transport assembly 1, an adjustment assembly 2, a flip assembly 3, and a transfer assembly 4. The transport assembly 1 is used to pick up the stator segments after they have been coated with glue and transfer them to the adjustment assembly 2. The adjustment assembly 2 rotates the stator segments placed there, ensuring alignment of the stator segment slots and improving the pass rate of the finished product after the stator segments are subsequently bonded.

[0037] The handling component 1 places the stator sheet after angle adjustment on the flipping component 3, and the flipping component 3 flips the stator sheet 180° so that the glue-coated side of the stator sheet faces downward. Finally, the transfer component 4 transfers the stator sheet with the glue-coated side facing downward to the press for bonding and pressing to form a stator.

[0038] like Figure 3 As shown, this is a structural diagram of the conveying component 1. The conveying component 1 is used to absorb the stator sheet after the upper surface is coated with glue. The conveying component 1 includes a conveying frame 101, a linear slide 102, a slide plate 103, a first lifting slide 104, a first lifting plate 105 and a suction mechanism. The conveying frame 101 is fixed to the machine platform by screws.

[0039] A linear slide 102 is fixed to one side of the transport frame 101. A slide 103 is connected to the linear slide 102. The linear slide 102 drives the slide 103 to move, thereby completing the transfer of the stator segments. Two first lifting slides 104 are fixed at intervals on the side of the slide 103 away from the transport frame 101. A first lifting plate 105 is connected to the first lifting slides 104. The first lifting slides 104 drive the first lifting plates 105 to move up and down, thereby completing the clamping and transportation of the stator segments.

[0040] The suction mechanism is fixed at the bottom of the first lifting plate 105 and is used to suck the stator sheet. There are two groups of suction mechanisms, one of which is used to suck the stator sheet with glue on the upper surface to the adjustment component 2, and the other is used to suck the stator sheet after the angle adjustment to the flip component 3, so as to achieve the consistency of the beat. Figure 4 As shown, the suction mechanism includes a support column 106 , an air plate 107 , a suction nozzle 108 , a pressure plate 109 , an air hole 110 and an avoidance hole 111 .

[0041] Support columns 106 are fixed to the bottom of first lift plate 105, and gas plate 107 is fixed to the bottom of support columns 106. The support columns 106 separate gas plate 107 and first lift plate 105, providing space for the installation of suction nozzles 108. Multiple suction nozzles 108 are arranged around gas plate 107 to absorb glue from the stator segments after the upper surface is coated with glue. The upper surface of the stator segments is where the glue is dispensed, and the suction nozzles 108 avoid the glue dispensing area during suction, so that the suction nozzles 108 do not interfere with the glue on the upper surface of the stator segments.

[0042] The pressure plate 109 is fixed to the bottom of the gas plate 107. Figure 5 As shown, the air hole 110 is annularly arranged on the pressure plate 109 and passes through the pressure plate 109, and the suction nozzle 108 on the air plate 107 is installed in the air hole 110. The avoidance hole 111 passes through the pressure plate 109. When sucking the stator sheet, it avoids the position of the glue on the stator sheet to avoid interference with the glue. At the same time, when placing the stator sheet, the avoidance hole 111 can avoid the position of the first positioning block 207 on the adjustment plate 204 to avoid interference with the first positioning block 207.

[0043] By fixing a pressure plate 109 at the bottom of the air plate 107, the pressure plate 109 lowers and presses on the stator plate when sucking the glue-dispensed stator plate, and then the stator plate is sucked by the suction nozzle 108 on the air plate 107. The pressure plate 109 ensures the levelness of the stator plate. If the suction nozzle 108 is used alone for suction, the levelness of the stator plate cannot be guaranteed during suction and transfer due to the limited suction position, which directly affects the subsequent assembly of the stator plate.

[0044] The adjustment component 2 is fixed on the machine table, and the stator sheet placed there is rotated with the cooperation of the CCD camera above to ensure that the wire slot position of each stator sheet corresponds to each other, avoiding the wire slot misalignment after the stator sheet is bonded. Figure 6 As shown, the adjustment assembly 2 includes an adjustment frame 201, an adjustment platform 202, a rotary motor 203, an adjustment plate 204, a first positioning block 207 and a first guide portion 208. The adjustment frame 201 is fixed on the machine platform and is located on one side of the transport frame 101.

[0045] The adjustment platform 202 is fixed to the top of the adjustment frame 201 by screw fastening, and the motor housing of the rotating motor 203 is fixed to the bottom of the adjustment platform 202. The rotating shaft of the rotating motor 203 passes through the adjustment platform 202 and is connected to the adjustment plate 204. The rotating motor 203 drives the adjustment plate 204 to rotate, thereby driving the stator plate on the adjustment plate 204 to complete the angle adjustment.

[0046] like Figure 7As shown, the first positioning block 207 is mounted on top of the adjustment plate 204. The suction mechanism absorbs the glue-coated stator segments and places them on the adjustment plate 204. Simultaneously, the wire slots on the inner side of the stator segments are inserted into the first positioning block 207. The first positioning block 207 positions the stator segments and prevents inertia from causing excessive rotation of the stator segments during rotation of the adjustment plate 204, which could lead to misalignment of the wire slots on the stator segments.

[0047] The first guide portion 208 is tiltedly disposed on the top of the first positioning block 207 to guide the stator sheet when inserting the stator sheet, thereby facilitating the insertion of the stator sheet.

[0048] The flip assembly 3 is fixed on the machine table and is located on one side of the adjustment assembly 2. It is used to receive the stator sheet placed there by the suction mechanism and flip the stator sheet 180° so that the glued surface of the stator sheet faces downwards, which is convenient for subsequent press-fitting and bonding. Figure 8 As shown, the flip assembly 3 includes a flip frame 301, a second lifting slide 302, a second lifting plate 303, a flip cylinder 304, a flip plate 305, a clamping plate 306, a clamping groove 307, an adjustment plate 308 and an adjustment groove 309, and the flip frame 301 is fixed to the machine platform by screws.

[0049] The second lifting slide 302 is vertically fixed to one side of the flip frame 301. The second lifting plate 303 is connected to the sliding portion of the second lifting slide 302, and is driven by the second lifting slide 302 to move the second lifting plate 303 up and down. The flip cylinder 304 is fixed to the side of the second lifting plate 303 away from the second lifting slide 302, and the flip plate 305 is fixed to the rotating portion of the flip cylinder 304. The cooperation between the second lifting slide 302 and the flip cylinder 304 completes the flipping of the stator segments after gluing.

[0050] like Figure 9 As shown, there are two clamping plates 306, fixed at intervals on the side of the flip plate 305 away from the flip cylinder 304. A clamping groove 307 is formed between the two clamping plates 306 for mounting an adjustment plate 308. The thickness of the adjustment plate 308 is equal to the height of the clamping groove 307. Therefore, when the adjustment plate 308 is inserted into the clamping groove 307 of the two clamping plates 306, the upper and lower clamping plates 306 limit the adjustment plate 308 from vertical shaking.

[0051] The adjustment slot 309 is in the shape of a rounded rectangle and passes through the clamping plate 306. A fixing hole is provided on the adjustment plate 308. During actual fixation, a fastening nut will be used to complete the fixation of the adjustment plate 308. By setting the adjustment slot 309, the position of the adjustment plate 308 can be appropriately adjusted, thereby fine-tuning the adjustment plate 308 and improving the position accuracy of the stator sheet absorption here.

[0052] Suction mechanisms are fixed to the top and bottom of the adjustment plate 308 to receive the stator piece after the angle adjustment transferred by the conveying assembly 1, and drive the stator piece to flip 180° vertically so that the glue-coated surface of the stator piece faces downward, which is convenient for subsequent press-fitting and bonding.

[0053] The transfer assembly 4 is fixed on the machine table and located below the flip assembly 3, and the stator sheet with the glued surface facing downward is transferred to the press for bonding and pressing, thereby forming a stator. Figure 10 As shown, the transfer assembly 4 includes a transfer frame 401, a transfer plate 402, a transfer disc 403, a placement slot 404, a second positioning block 405, and a second guide portion 406. The transfer frame 401 is fixed to the machine platform by screws, and the transfer plate 402 is mounted on top of the transfer frame 401 via a rotary motor. The rotary motor drives the transfer plate 402 to rotate, thereby transferring the stator sheets with the glue-coated surface facing downward to the press for bonding and pressing, thereby forming the stator.

[0054] There are two transfer discs 403, which are fixed at intervals on the top of the transfer plate 402. With the cooperation of the transfer plate 402, the efficiency of the transfer is improved. The placement groove 404 is annular and is opened on the top of the transfer disc 403. The flip assembly 3 places the flipped stator plate on the transfer disc 403. The inner diameter of the placement groove 404 is larger than the inner diameter of the stator plate, and the outer diameter of the placement groove 404 is smaller than the outer diameter of the stator plate. Under the premise of meeting the stator plate's acceptance, try to avoid contact with the lower surface of the stator plate. Therefore, at this time, the stator plate has been flipped by the flip assembly 3, and the glued surface is facing downward, and the middle part of the stator plate is in a suspended state, avoiding excessive contact with the transfer disc 403 to wipe off the glue on the lower surface of the stator plate.

[0055] The second positioning block 405 is arranged around the top of the placement groove 404. The flipping assembly 3 places the flipped stator segment on the transfer plate 403. At this time, the wire groove on the inner side of the stator segment is inserted into the second positioning block 405. The inserted stator segment is positioned by the second positioning block 405 to prevent the stator segment from being offset during transfer.

[0056] The second guide portion 406 is obliquely provided on the top of the second positioning block 405 to guide the stator sheet when inserting the stator sheet, thereby facilitating the insertion of the stator sheet.

[0057] The transfer assembly 4 rotates the stator sheets to the outside, and an external suction mechanism sucks them to the bottom of the press. The stator sheets are pressed together by the press to form a stator structure.

[0058] The working principle of the stator sheet transfer device for a motor of the utility model is as follows:

[0059] The stator sheet with glue applied to its surface is sucked up by the transport component 1 and transferred to the adjustment component 2. The adjustment component 2 adjusts the angle of the stator sheet placed there to ensure that the wire slots of the stator sheet are aligned. The transport component 1 places the stator sheet with adjusted angle on the flip component 3. The flip component 3 flips the stator sheet 180° so that the glue-coated surface of the stator sheet faces downward. Finally, the transfer component 4 transfers the stator sheet with the glue-coated surface facing downward to the press for bonding and pressing, thereby forming the stator.

[0060] The stator sheet transfer device for a motor of the utility model has a simple structure and a high degree of automation. Compared with manual transfer, the transfer efficiency of the stator sheets is greatly improved. Moreover, no height difference will appear between the stator segments that are plugged into each other during transfer, thereby ensuring the qualified rate and integrity of the stator finished product after bonding. Moreover, the stator sheets will be rotated at an angle during the transfer process to ensure that the stator sheets are engaged with each other after bonding, thereby improving the stability of the structure after the subsequent stator sheets are bonded, and preventing the stator sheets from being broken apart due to force during use.
