Description

Technical Field

[0001] The invention relates to the technical field of patch inductor manufacturing, in particular to a double-station conductor plate material storage mechanism. Background Art

[0002] Chip inductors are electromagnetic induction components made of insulated wires, and are mainly used in the production and manufacturing technology fields of laptop computers, automotive electronic accessories, Bluetooth headsets, and audio. The molding process of chip inductors is roughly as follows: first, the spring coil is welded and fixed on the wire board, and then the pieces are cut and processed into chip inductors.

[0003] Before officially executing the welding process of the spring coil, it is necessary to use a vacuum suction cup to remove the wire board from the wire board placement tooling and transfer it to the wire board carrying fixture. The Chinese invention patent with application number 2020205095013 discloses a wire board placement tooling, which consists of a base and a placement function part. Among them, the base includes a first support member and a second support member. The placement function part includes a flat plate, a first stop member and a second stop member. The flat plate is horizontally clamped and fixed between the above-mentioned first support member and the second support member. The flat plate is detachably connected to the above-mentioned first support member and the second support member by means of screws. Accordingly, the first support member and the second support member are respectively provided with a first waist-shaped through hole and a second waist-shaped through hole that are compatible with the above-mentioned screws. As can be seen from the above description, there is only one conductor board placement tool. Therefore, when the conductor board inside is exhausted, the machine needs to be stopped to complete the replenishment of the conductor board. The entire replenishment process takes a long time, which greatly increases the auxiliary time required for the production of chip inductors and seriously reduces the production efficiency of chip inductors. Therefore, it is urgent for technicians to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a double-station wire board storage mechanism which has a simple structural design, is easy to manufacture and form, and ensures uninterrupted supply of guide plates.

[0005] In order to solve the above technical problems, the present invention relates to a double-station wire board storage mechanism, which includes a base, a guide assembly, a transition plate, a linear motion drive unit, a first wire board placement tool and a second wire board placement tool. The guide assembly is composed of a slider and a slide rail. The slide rail runs along the left and right directions and is detachably fixed on the base. The first wire board placement tool and the second wire board placement tool are both used to store wire boards and are fixed on the transition plate side by side along the left and right directions. The transition plate is fixed to the slider, and under the driving force of the linear motion drive unit, the first wire board placement tool and the second wire board placement tool are driven to perform directional sliding motion along the slide rail.

[0006] As a further improvement of the technical solution of the present invention, the first wire board placement tool includes a first base, a first stopper and a second stopper. The first base is detachably fixed to the upper plane of the transition plate. The first stopper and the second stopper are both fixed to the first base and are oppositely arranged. A first slide groove and a second slide groove are respectively provided on the opposite side walls of the first stopper and the second stopper, which are used together to limit the wire board. The second wire board placement tool includes a second base, a third stopper and a fourth stopper. The second base is also detachably fixed to the upper plane of the transition plate. The third stopper and the fourth stopper are both fixed to the second base and are oppositely arranged. A third slide groove and a fourth slide groove are respectively provided on the opposite side walls of the third stopper and the fourth stopper, which are used together to limit the wire board.

[0007] As a further improvement of the technical solution of the present invention, the width dimension of the wire plate is assumed to be a, and its length dimension is assumed to be b; the widths of the first and second chutes are consistent and are both assumed to be a1; the distance between the bottom walls of the first and second chutes is assumed to be b1; then 0.15mm≥a1-a≥0.1mm, 0.25mm≥b1-b≥0.2mm. The widths of the third and fourth chutes are consistent and are both assumed to be a2; the distance between the bottom walls of the third and fourth chutes is assumed to be b2, then 0.15mm≥a2-a≥0.1mm, 0.25mm≥b2-b≥0.2mm.

[0008] As a further improvement of the technical solution of the present invention, the first material stopper and the second material stopper are both detachably connected to the transition plate by means of a first fastener, and correspondingly, the first material stopper and the second material stopper are respectively provided with a first mounting through hole and a second mounting through hole adapted to the first fastener. The third material stopper and the fourth material stopper are both detachably connected to the transition plate by means of a second fastener, and correspondingly, the third material stopper and the fourth material stopper are respectively provided with a third mounting through hole and a fourth mounting through hole adapted to the second fastener.

[0009] As a further improvement of the technical solution of the present invention, a wear-resistant coating is provided in the first slide groove, the second slide groove, the third slide groove and the fourth slide groove.

[0010] As a further improvement of the technical solution of the present invention, the above-mentioned linear motion drive unit includes a cylinder and an L-shaped force transmission member. The cylinder is composed of a cylinder body and a piston rod. The L-shaped force transmission member is connected by a first side plate and a second side plate. The first side plate is fixedly connected to the transition plate by means of a third fastener, and a first waist-shaped hole extending in the left-right direction is provided on the first side plate. The second side plate is fixedly connected to the piston rod, and a second waist-shaped hole extending in the front-back direction is provided on the second side plate for the piston rod to pass through.

[0011] As a further improvement of the technical solution of the present invention, the linear motion drive unit further includes a fixing seat. The fixing seat is used to support and carry the cylinder body, and is detachably fixed to the upper plane of the base by means of a fourth fastener. A third waist-shaped hole extending along the front-back direction is provided in the fixing seat for the fourth fastener to pass through.

[0012] As a further improvement of the technical solution of the present invention, the linear motion drive unit further comprises a limiter, which is fixed on the upper plane of the base and is located directly to the left of the guide assembly.

[0013] Compared with the wire board storage mechanism of the traditional design structure, in the technical solution disclosed in the present invention, two sets of wire board placement tools are arranged side by side. When the wire boards in one set of wire board placement tools are exhausted, the other set of wire board placement tools performs translational movement under the action of the linear motion drive unit until it replaces the position of the previous set of wire board placement tools, and continues to feed the wire boards. At the same time, the previous set of wire board placement tools is refilled. In this way, the time required for stopping for refilling is eliminated, thereby effectively reducing the auxiliary time required for the production of chip inductors, and greatly improving the production efficiency of chip inductors.

DETAILED DESCRIPTION

[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , 2 The relative position diagram of the double-station wire board storage mechanism of the present invention in the wire board automatic welding equipment and its partial enlarged diagram are respectively shown. It can be seen that it is located at the front process of the spring coil welding process, and multiple pre-welded wire boards are stacked and placed in it in advance.

[0024] Figure 3 , Figure 4 The three-dimensional schematic diagram and the front view of the double-station wire board storage mechanism of the present invention are respectively shown. It can be seen that it mainly consists of a base 1 (such as Figure 2As shown in the figure), the guide assembly 2, the transition plate 3, the linear motion drive unit 4, the first wire board placement tool 5 and the second wire board placement tool 6 are composed of several parts. Among them, the guide assembly 2 is composed of a slider 21 and a slide rail 22. The slide rail 22 runs along the left and right direction and is detachably fixed on the base 1. The first wire board placement tool 5 and the second wire board placement tool 6 are both used to store and place wire boards, and are fixed on the transition plate 3 side by side along the left and right direction. The transition plate 3 is fixed to the slider 21, and under the driving force of the above-mentioned linear motion drive unit 4, the first wire board placement tool 5 and the second wire board placement tool 6 are simultaneously driven to perform directional sliding movement along the slide rail 22. In this way, the time required for stopping the machine for replenishing materials is eliminated, thereby effectively reducing the auxiliary time required for the production of chip inductors, and greatly improving the production efficiency of chip inductors.

[0025] The working principle of the above-mentioned double-station wire board storage mechanism is as follows: when the wire boards in the first wire board placement tool 5 are exhausted, the second wire board placement tool 6 moves in a horizontal direction under the action of the linear motion drive unit 4 until it replaces the position of the first wire board placement tool 55, and continues to feed the wire boards. During this period, the staff performs the operation of replenishing the wire boards on the first wire board placement tool 5. The first wire board placement tool 5 and the second wire board placement tool 6 operate alternately to complete the uninterrupted feeding of the production line. Vice versa.

[0026] As a further optimization of the structure of the double-station wire board storage mechanism, the first wire board placement tool 5 preferably includes a first base 51, a first stopper 52 and a second stopper 53. The first base 51 is detachably fixed to the upper plane of the transition plate 3. The first stopper 52 and the second stopper 53 are both fixed to the first base 51 and are oppositely arranged. A first slide groove 521 and a second slide groove 531 are respectively provided on the opposite side walls of the first stopper 52 and the second stopper 53, which are used together to limit the wire board. The second wire board placement tool 6 preferably includes a second base 61, a third stopper 62 and a fourth stopper 63. The second base 61 is also detachably fixed to the upper plane of the transition plate 3. The third stopper 62 and the fourth stopper 63 are both fixed to the second base 61 and are oppositely arranged. A third slide groove 621 and a fourth slide groove 631 are respectively provided on the opposite side walls of the third stopper 62 and the fourth stopper 63 to limit the position of the wire plate (such as Figure 4By adopting the above technical solution, on the one hand, under the premise of ensuring that the wire boards are reliably stacked in the first wire board placement tool 5 and the second wire board placement tool 6, the first wire board placement tool 5 and the second wire board placement tool 6 have a simpler design structure as much as possible, which is conducive to their manufacture and assembly; on the other hand, the relative position of the wire boards can be more accurately defined, which is conducive to the subsequent material picking operation of the robot.

[0027] Generally speaking, considering the convenience of the wire board placement and removal operations and the accuracy of the wire board's own position, it is necessary to limit the specific dimensions of the first wire board placement tool 5 and the second wire board placement tool 6, as follows: the width dimension of the wire board is assumed to be a, and its length dimension is assumed to be b; the widths of the first slide groove 521 and the second slide groove 531 are consistent, and both are assumed to be a1; the distance between the bottom walls of the first slide groove 521 and the second slide groove 531 is assumed to be b1; then 0.15mm≥a1-a≥0.1mm, 0.25mm≥b1-b≥0.2mm. The widths of the third slide groove 621 and the fourth slide groove 631 are consistent, and both are assumed to be a2; the distance between the bottom walls of the third slide groove 621 and the fourth slide groove 631 is assumed to be b2, then 0.15mm≥a2-a≥0.1mm, 0.25mm≥b2-b≥0.2mm (such as Figure 4 , 5 ).

[0028] Furthermore, the first stopper 52 and the second stopper 53 are preferably fixed to the transition plate 3 in a detachable manner, as follows: the first stopper 52 and the second stopper 53 are detachably connected to the transition plate 3 by means of a first fastener, and correspondingly, a first mounting through hole 522 and a second mounting through hole 532 that are compatible with the first fastener are respectively provided in the first stopper 52 and the second stopper 53. The third stopper 62 and the fourth stopper 63 are preferably fixed to the transition plate 3 in a detachable manner by means of a second fastener, and correspondingly, a third mounting through hole 622 and a fourth mounting through hole 632 that are compatible with the second fastener are respectively provided in the third stopper 62 and the fourth stopper 63 (such as Figure 4 , 5 As shown in ). In this way, on the one hand, it is convenient to redesign the first wire board placement tool 5 and the second wire board placement tool 6 in the later stage to expand their application scope; on the other hand, when the first material stopper 52, the second material stopper 53, the third material stopper 62 and the fourth material stopper 63 are worn or damaged, it is convenient to replace them, thereby effectively reducing the later maintenance cost.

[0029] Of course, in order to improve the wear resistance of the working surfaces of the first stopper 52, the second stopper 53, the third stopper 62 and the fourth stopper 63 and ensure their service life, a wear-resistant coating (not shown in the figure) can also be provided in the first slide groove 521, the second slide groove 531, the third slide groove 621 and the fourth slide groove 631.

[0030] As a further optimization of the structure of the double-station wire board storage mechanism, the linear motion drive unit preferably includes a cylinder 41 and an L-shaped force transmission member 42. The cylinder 41 is composed of a cylinder body 411 and a piston rod 412. The L-shaped force transmission member 42 is connected by a first side plate 421 and a second side plate 422. The first side plate 421 is fixedly connected to the transition plate 3 by means of a third fastener, and a first waist-shaped hole 4211 extending along the left-right direction is provided thereon. The second side plate 422 is fixedly connected to the piston rod 412, and a second waist-shaped hole 4221 (such as a second waist-shaped hole 4221 extending along the front-back direction for the piston rod 412 to pass through is provided thereon. Figure 4 , 5 , 6). By adopting the above technical solution, it is convenient to make real-time adjustments according to actual conditions to ensure that the cylinder 41 has a correct assembly and connection relationship with respect to the transition plate 3, thereby relaxing the requirements on the relative installation position accuracy of the cylinder 41.

[0031] Generally speaking, the cylinder 41 is preferably connected to the base 1 by means of a fixing seat 43. The fixing seat 43 is used to support and carry the cylinder body 41, and is detachably fixed to the upper plane of the base 1 by means of a fourth fastener. The fixing seat 43 is provided with a third waist-shaped hole 431 (such as a third waist-shaped hole 431) extending along the front-back direction and for the fourth fastener to pass through. Figure 5 As shown in FIG. 4 , the relative position of the cylinder 41 can be easily adjusted along the front-rear direction, thereby effectively reducing the difficulty of installing the cylinder 41.

[0032] Finally, in order to limit the limit position of the transition plate 3 in the left-right direction and ensure the operation safety of the double-station wire board storage mechanism, the linear motion drive unit 4 can also be provided with a limiter 44 according to specific circumstances. The limiter 44 is detachably fixed on the upper plane of the base 1 and is located directly to the left of the guide assembly 2 (such as Figure 4 ).

[0033] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
