Description

Technical Field

[0001] This invention relates to the field of surface mount inductor processing equipment, and more specifically, to a transfer device for edge trimming of surface mount inductors. Background Technology

[0002] In the production of surface mount inductors, especially those manufactured using a one-piece molding process, the workpieces need to undergo edge trimming. Since the spacing between the feed slots of the edge trimming equipment and the feed slots of the subsequent workpieces are different, a transfer structure is required for conveying, or a single conveyor can be used. The former transfer structure is mostly more complex, requiring multi-directional drive components for adjustment and repositioning, which is troublesome and costly; the latter has low overall efficiency and needs improvement. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a transfer device for edge trimming of chip inductors. It has a simple structure, adopts an opening and closing structure, is suitable for intermediate transfer of workpieces before and after edge trimming, is easy to use and operate, and has a low cost.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] This invention provides a transfer device for trimming surface mount inductors, including a linear slide table and a clamping device mounted on a slider of the linear slide table. The clamping device includes a bracket with multiple material slots mounted on its top surface. The first material slot is fixed to the bracket, and the material slots are adjusted by an opening and closing structure to achieve opening and closing actions. When the multiple material slots are in an unfolded and separated state, they are used to receive workpieces sent from the upstream trimming equipment. When the multiple material slots are in a tightly closed state, they are used to transfer the readjusted workpieces to the downstream equipment. In the unfolded and separated state, the opening and closing structure, together with a driving blocking structure, forms a blockage on the outer side of the port of the material slot away from the feed end.

[0006] In a preferred embodiment of the present invention, the material trough is provided with a plurality of guide holes penetrating two opposite side walls, and two adjacent material troughs are connected and cooperated by a connecting rod passing through the guide hole. The plurality of material troughs open and close along the direction of the connecting rod under the drive of the opening and closing structure.

[0007] In a preferred embodiment of the present invention, a recessed groove extending along the length direction is provided on one side wall of the material trough, and all guide holes fall into the recessed groove; a first countersunk hole is provided at the end of the guide hole away from the recessed groove, and a second countersunk hole is provided at the bottom of the first countersunk hole; a threaded head is fixedly provided at one end of the connecting rod, and a nut is installed at the other end; the threaded head is threadedly connected to the first countersunk hole, the diameter of the second countersunk hole is greater than the maximum outer diameter of the nut, and the depth of both the second countersunk hole and the recessed groove is greater than the length of the nut; the material trough unfolds along the connecting rod, and unfolds to a preset distance with the nut and the threaded head as nodes, and can also be restored to a tightly abutting state along the connecting rod.

[0008] In a preferred embodiment of the present invention, the opening and closing structure includes a cylinder, a pusher, a first pusher, and a spring; the pusher includes a tube with one end sealed and a retaining ring fixedly disposed on the outside of the open end of the tube; the cylinder is bolted to the side wall of the bracket, and the tube is mounted on the piston rod end of the cylinder by a pin; the top of the first pusher is bolted to the bottom of the side wall of the material trough at the end position, and the bottom of the first pusher is provided with a first through hole, the diameter of the first through hole being adapted to the diameter of the tube, and a retaining spring for blocking the first pusher is installed at the end of the tube; the spring is sleeved on the tube and clamped between the first pusher and the retaining ring; the cylinder drives the first pusher to move, which in turn drives the material trough at the end position to move, thereby driving the other material troughs to move to achieve the opening or closing action.

[0009] In a preferred embodiment of the present invention, the blocking structure includes a second pusher and a plurality of swing blocks; the swing blocks are rotatably mounted on the side of the trough near the first trough direction at the port of the trough by bolts; the bottom of the second pusher is mounted on the wall surface of the retaining ring away from the spring, and the second pusher moves with the pusher head; a support rod is fixedly provided on the top of the second pusher, and the support rod slides close to the end face of the trough, and the support rod has notches corresponding to the plurality of swing blocks; when the cylinder drives the second pusher to compress the spring, the support rod pushes the swing blocks upward and swings them up, blocking the end opening of the trough; when the cylinder drives the second pusher to move in the opposite direction, the pushing on the swing blocks is released, and the swing blocks fall into the notches, releasing the obstruction of the trough port.

[0010] The beneficial effects of this invention are as follows:

[0011] This invention provides a transfer device for trimming chip inductors. The material troughs are adjusted through an opening and closing structure to achieve opening and closing actions. When multiple material troughs are in an unfolded and separated state, they are used to receive workpieces sent from the upstream trimming equipment. When multiple material troughs are in a tightly closed state, they are used to transfer the readjusted workpieces to the downstream equipment. This device satisfies the transfer and transformation of different material trough spacings between upstream and downstream equipment, and can operate multiple workpieces simultaneously, effectively improving work efficiency.

[0012] When the material trough is in the unfolded and separated state, the opening and closing structure drives the blocking structure to form a block on the outside of the port of the material trough away from the feeding end, so as to block and limit the workpiece input from the upstream and facilitate the arrangement; when it is in the tightly closed state, the blocking structure releases the blocking action, and the material can be discharged from both ends, which is better adapted to different processing equipment; and the overall structure is simple, easy to use and operate, and has a low cost.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 5As shown in the figure, a transfer device for trimming surface mount inductors is disclosed in a specific embodiment of the present invention. It includes a linear slide 100 and a clamping device 200 mounted on the slider of the linear slide. The clamping device 200 includes a bracket 210, and multiple material slots 220 are mounted on the top surface of the bracket 210. The first material slot is fixed on the bracket. The material slots 220 are adjusted by an opening and closing structure 300 to achieve opening and closing actions. When the multiple material slots are in an unfolded and separated state, they are used to receive workpieces sent from the upstream trimming equipment. When the multiple material slots are in a tightly closed state, they are used to transfer the readjusted workpieces to the downstream equipment. When the material slots 220 are in an unfolded and separated state, the opening and closing structure 300, along with a driving blocking structure 400, forms a blockage on the outer side of the port of the material slot 220 away from the feed end.

[0025] This invention provides a transfer device for trimming chip inductors. The material troughs are adjusted through an opening and closing structure to achieve opening and closing actions. When multiple material troughs are in an unfolded and separated state, they are used to receive workpieces sent from the upstream trimming equipment. When multiple material troughs are in a tightly closed state, they are used to transfer the readjusted workpieces to the downstream equipment. This device satisfies the transfer and transformation of different material trough spacings between upstream and downstream equipment, and can operate multiple workpieces simultaneously, effectively improving work efficiency.

[0026] When the material trough is in the unfolded and separated state, the opening and closing structure drives the blocking structure to form a block on the outside of the port of the material trough away from the feeding end, so as to block and limit the workpiece input from the upstream and facilitate the arrangement; when it is in the tightly closed state, the blocking structure releases the blocking action, and the material can be discharged from both ends, which is better adapted to different processing equipment; and the overall structure is simple, easy to use and operate, and has a low cost.

[0027] Furthermore, the material trough 220 is provided with multiple guide holes 221 penetrating the two opposite side walls. Adjacent material troughs 220 are connected and cooperated by connecting rods 230 passing through the guide holes 221. Multiple material troughs open and close along the direction of the connecting rods under the drive of the opening and closing structure. The structure is simple, the movement direction of the material trough is limited by the connecting rods, and the material trough can move smoothly. It should be noted that at least two connecting rods are used to connect and cooperate between adjacent material troughs.

[0028] Furthermore, such as Figure 3 , Figure 4As shown, a recessed groove 222 extending along the length direction is provided on one side wall of the material trough 220, and all guide holes 221 fall into the recessed groove 222; a first countersunk hole 223 is provided at the end of the guide hole 221 away from the recessed groove 222, and a second countersunk hole 224 is provided at the bottom of the first countersunk hole 223; a threaded head 231 is fixedly provided at one end of the connecting rod 230, and a nut 232 is installed at the other end; the threaded head 231 is threadedly connected to the first countersunk hole 223, and the diameter of the second countersunk hole 224 is larger than the maximum outer diameter of the nut 232, and the second countersunk hole 224 and the recessed groove 222 are connected in a threaded manner. The depth of 22 is greater than the length of nut 232; the material groove unfolds along the connecting rod and unfolds to a preset distance with the nut and threaded head as nodes, and can also be restored to a tight-fitting state along the connecting rod; the connection between the first countersunk hole and the threaded head fixes one end of the connecting rod, limiting the movement limit position of one end; the setting of the second countersunk hole can provide space for the connecting rod in the closed state of the material groove, preventing the connecting rod from being blocked and causing the material groove to not fit tightly; among them, one end of the connecting rod is a detachable nut, which facilitates the disassembly and assembly of the overall structure.

[0029] Furthermore, such as Figure 5 As shown, the opening and closing structure 300 includes a cylinder 310, a pusher 320, a first pusher 330, and a spring 340. The pusher 320 includes a tube 321 with one end sealed, and a retaining ring 322 fixedly disposed on the outside of the open end of the tube 321. The cylinder 310 is bolted to the side wall of the bracket 210, and the tube 321 is mounted to the piston rod end of the cylinder 310 by a pin. The top of the first pusher 330 is bolted to the bottom of the side wall of the material trough 220 at the end position, and the bottom of the first pusher 330 is provided with a first through hole 331, the diameter of which is the same as the diameter of the tube 321. The tube body is fitted with a retaining spring at its end to block the first pusher; the spring 340 is sleeved on the tube body 321 and clamped between the first pusher 330 and the retaining ring 322; the cylinder drives the first pusher to move, which in turn drives the material trough at its end to move, thereby driving the other material troughs to move to achieve the opening or closing action; the above structural design can use the spring as an intermediate buffer to provide the basic conditions for the subsequent blocking structure to drive; it should be noted that the spring force is sufficient to support the pushing of the material trough to complete the opening action; especially under the continuous pushing of the cylinder, it can ensure that the material trough can be opened into place.

[0030] Furthermore, the blocking structure 400 includes a second pusher 410 and multiple swing blocks 420; the swing blocks 420 are rotatably mounted on the side of the port of the feed trough 220 near the first feed trough direction by bolts; the bottom of the second pusher 410 is mounted on the wall of the retaining ring 322 away from the spring 340, and the second pusher 410 moves with the pusher head 320; a support rod 411 is fixedly provided on the top of the second pusher 410, and the support rod 411 slides close to the end face of the feed trough 220, and the support rod 411 has notches 412 corresponding to the multiple swing blocks 420; when the cylinder drives the second pusher to compress the spring, the support rod... The jacking swing block swings upwards to block the end opening of the material trough; when the cylinder drives the second pusher to move in the opposite direction, it releases the jacking of the swing block, and the swing block falls into the notch, releasing the blockage at the end of the material trough. The above structural design uses a spring to provide space adjustment for the secondary jacking, and achieves the use of the same cylinder for driving, reducing the overall equipment cost. Furthermore, the cooperation between the swing block and the notch of the support rod can achieve the effect of blocking when loading and releasing when unloading. The structure is simple, cleverly utilizing the movement and cooperation between structural components, requiring no 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 material trough at the end position 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 material trough at the end position in the unfolded state.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
