DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1-Figure 3 The lower part of the frame of the motor core loading machine is made of profiles, and there is a flat mounting plate on the upper part. There are two material racks 3 on one side of the mounting plate. The two material racks 3 respectively place the material plate 2 with the core and the empty material plate. The translation mechanism takes the material plate 2 with the core from the material rack 3 on one side, and drives it to the middle after moving. The core is clamped by the transfer mechanism. On the other side of the frame 1, there is a mechanism for conveying the core shaft, and on one side of the conveying mechanism, there is a mechanism for rotating and positioning the core shaft. The core shaft is rotated and positioned, which is convenient for the transfer mechanism to drive the core to be assembled on the core shaft.

[0027] The translation guide rail 4 of the translation mechanism is fixed on the plane on the upper side of the frame 1. There is a supporting movable plate 5 on this translation guide rail 1. The first cylinder 6 fixed on the movable plate 5 drives the lifting plate 7 to move up and down. The raised positioning head on the lifting plate 7 can dock with the bottom groove of the material plate 2. After docking, the first cylinder 6 continues to push upward and releases the support limit of the material plate 2 through the mechanism for supporting the material plate. The material plate 2 moves downward under the support of the first cylinder 6. The supporting mechanism is stuck between the two material plates 2, so that one of the material plates 2 can be taken to drive the iron core to move to the middle. The movable plate 5 is fixedly connected to the belt 10. The mobile motor 8 can drive the movable plate 5 to move horizontally on the translation guide rail 4 through the cooperation of the pulley and the belt 10.

[0028] See also Figure 4 and Figure 5 In order to facilitate the stacking and separation of the material sheet 2 from the material rack 3, a second cylinder 16 is fixed on the bracket 11 through a cylinder mounting seat 15, and a "Z"-shaped material sheet texture 17 is installed in the inner cylinder of the space in the middle of the cylinder mounting seat 15 through a torsion spring and an axis: The operation of removing the sheet 2 from the rack 3 is as follows: First, the moving plate 5 is moved to the Figure 1 At the bottom of the left material rack 3, the first cylinder 6 is started to drive the material plates 2 in the entire material rack 3 to move upward, and the lowermost material plate 2 is separated from the material plate support rod 17. At this time, the second cylinder 16 is started to press the other side of the material plate support rod 17, so that the end of the material plate support rod 17 is tilted upward, and the material plate support rod 17 is away from the material plate 2. The first cylinder 6 then drives all the material plates 2 to move down a certain distance, and the second cylinder 16 is reset. Under the action of the torsion spring, the material plate support rod 17 is also reset, and its front end is located below the second to last material plate 2. The first cylinder 6 continues to move downward, so that the lowermost material plate 2 can be separated from the material rack 3, and the material plate 2 moves driven by the movable plate 5.

[0029] The operation of placing sheet 2 on rack 3 is as follows: The moving plate 5 drives the material plate 2 to move to Figure 1 Below the middle right material plate 3, the first cylinder 6 drives the material plate 2 to move upward, and uses the edge of the material plate 2 to push up the material plate support rod 17 installed in the cylinder mounting seat 15. When the material plate 2 exceeds the material plate support rod 17, the material plate support rod 17 is reset under the action of gravity and the torsion spring, and the first cylinder 6 drives the material plate 2 to move downward, and the material plate 2 contacts the material plate support rod 17 to complete the placement.

[0030] A cylinder can be installed on the cylinder mounting seat 15 at the right side of the material rack 3 to assist the rotation of the material plate support rod 17.

[0031] See also Figure 6 The transfer mechanism is fixed to the frame 1 through the gantry 18, the claw cylinder 22 is fixed to the claw cylinder mounting plate 21, the claw cylinder mounting plate 21 is driven by the first slide cylinder 19 and the second slide cylinder 20 to move left and right and up and down, and the claw 23 at the lower end of the claw cylinder 22 can clamp the iron core.

[0032] See also Figure 7-Figure 9 , the mounting frame 26 of the rotating mechanism and the feeding guide rail 24 are fixedly mounted on the frame 1, and a feeding plate 25 is arranged on the feeding guide rail 24, on which an iron core shaft is placed, and the transfer operation of the feeding plate 25 is completed by other conveying mechanisms, and a shaft sleeve for placing the iron core shaft is arranged in the middle of the feeding plate 25, so that the iron core shaft can rotate, and the third cylinder 29 installed on the mounting frame 26 can drive the translation plate 28 to move on the first guide rail 27, and the fourth cylinder 32 installed on the translation plate 28 can drive the lifting frame 31 to move on the second guide rail 30, and the cooperation of the third cylinder 29 and the fourth cylinder 32 drives the rotating motor 33 fixed on the lifting frame 31 to move, and the rotating sleeve 34 at the lower end of the rotating motor 33 is docked with the iron core shaft on the feeding plate 25, and under the drive of the rotating motor 33, the iron core shaft can rotate, so that the groove on the iron core shaft is oriented to cooperate with the protrusion on the iron core, so as to facilitate the docking installation of the iron core.

[0033] See also Figure 7 and Fig.10 The fifth cylinder 36 of the core shaft positioning mechanism is installed on the positioning bracket 35. The fifth cylinder 36 drives the positioning head 37 to move forward and contact the core shaft. The core shaft rotates under the drive of the rotating mechanism. When the protrusion at the front end of the positioning head 37 and the groove on the core shaft are on the same straight line, the protrusion is driven by the fifth cylinder 36 to be inserted into the core shaft to complete the positioning of the core shaft.

[0034] See also Fig.11There are material plate connecting rods 38 at the four corners of the material plate 2. The protrusions at the top of the material plate connecting rods 38 can be inserted into the corresponding grooves at the bottom of the material plate 2, which is convenient for multiple material plates 2 to be docked. At the same time, the limiting protrusions 39 arranged on the material plate 2 are docked with the through holes in the middle of the iron core. There are card grooves on the side walls of the limiting protrusions 39. The card block protruding inwardly in the middle of the iron core is inserted into the card groove to fix the iron core. The top of the card groove of the limiting protrusion 39 is an outward-expanding arc structure, which is convenient for the card block in the center of the iron core to slide into and dock.

[0035] The direction of the slot on the side wall of the limiting protrusion 39 is opposite to the direction of the protrusion of the positioning head 37. After the iron core is placed on the limiting protrusion 39, the block on the inner side of the iron core is in the same direction as the protrusion of the limiting head 37. In this way, the iron core will not rotate when the grasping movement is performed. After the limiting head 37 completes the positioning of the iron core shaft, it is convenient for the groove on the iron core shaft to dock with the block in the middle of the iron core.

[0036] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
