[0025] The present invention provides a transfer device for chip inductor trimming processing. The material trough is adjusted by the opening and closing structure to realize the opening and closing action. When multiple material troughs are in an expanded and separated state, they are used to receive the workpieces sent from the upstream trimming equipment; when multiple material troughs are in a close and closed state, they are used to transfer the readjusted workpieces to the downstream equipment. The device can meet the transfer transformation of different material feeding trough spacings of the front and rear equipment, and can operate multiple workpieces at the same time, effectively improving the work efficiency.

[0026] Among them, when the material trough is in an expanded and separated state, the opening and closing structure jointly drives the blocking structure to form a blockage on the outer side of the port of the material trough away from the feeding end, so as to block and limit the workpieces input from the upstream and facilitate arrangement; when it is in a tightly closed state, the blocking structure releases the blocking action, and both heads can discharge materials, which is better adapted to different processing equipment; and the overall structure is simple, the operation is simple, and the cost is low.

[0027] Furthermore, the material trough 220 is provided with a plurality of guide holes 221 penetrating two opposite side walls, and two adjacent material troughs 220 are connected and cooperated by a connecting rod 230 passing through the guide holes 221, and the plurality of material troughs are opened and closed along the direction of the connecting rod driven by the opening and closing structure; the structure is simple, and the moving direction of the material trough is limited by the connecting rod, and the material trough can move smoothly; it should be pointed out that two adjacent material troughs are connected and cooperated by at least two connecting rods.

The depth of 22 is greater than the length of the nut 232; the material trough is expanded along the connecting rod, and is expanded to a preset spacing with the nut and the threaded head as nodes, and can also be restored to a tightly abutted state along the connecting rod; one end of the connecting rod is fixed by the connection between the first countersunk hole and the threaded head, and the limit of movement of one end is limited; the setting of the second countersunk hole can provide a space for the connecting rod in a tightly closed state of the material trough to accommodate the material trough, thereby preventing the connecting rod from being blocked and causing the material trough to be unable to fit tightly; wherein, one end of the connecting rod is a detachable nut, which is convenient for the disassembly and assembly of the overall structure.

The structure is simple, and the mobile cooperation between the structural components is cleverly used. There is no need for excessive structure, and the overall structure is more compact.

[0031] Furthermore, a limiting bolt is installed on the top surface of the bracket. The limiting bolt is located on the side of the end position of the material trough away from the center of the bracket. The limiting bolt protrudes higher than the top surface of the bracket and is used to block the end position of the material trough in the expanded state.
