Description

Technical Field

[0001] The invention relates to the technical field of patch inductor manufacturing, in particular to a spring coil transfer 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] After the spring coil is wound and formed on the core shaft of the spring machine, it needs to be transferred to the wire board placement fixture with the help of a spring coil transfer mechanism and a manipulator. The Chinese invention patent with application number 2020205095066 discloses a spring automatic material receiving mechanism adapted to a spring machine (the function is the same as the above-mentioned spring coil transfer mechanism), which includes a base, a first linear motion part, a support, a second linear motion part, an L-shaped material receiving arm and a material receiving rod. Among them, the support member is arranged directly above the base, and is translated relative to the base in the front-to-back direction under the action of the first linear motion part. The second linear motion part is fixed to the support member. The L-shaped material receiving arm is fixed to the second linear motion part, and moves relative to the base in the up-and-down direction under the action of the second linear motion part. The material receiving rod is vertically fixed to the L-shaped material receiving arm, and it is adapted to the inner diameter of the formed spring coil (such as Figure 1 , 2 As shown in ). Although the above-mentioned spring automatic material receiving mechanism effectively eliminates or reduces the inventory problem of spring coils and eliminates the phenomenon of human operation errors, there are also the following problems: 1) The material receiving rod is poorly removable and inconvenient to operate; when the model of the spring coil to be transferred changes, it is not convenient to modify the design of the spring automatic material receiving mechanism; 2) There is a lack of effective circumferential rotation limit on the material receiving rod. In the process of transfer, the spring coil is very likely to rotate circumferentially relative to the material receiving rod due to the inertial force, so that it has a wrong posture. In this way, on the one hand, it directly affects the alignment accuracy of the subsequent spring coil and the coil placement groove on the wire plate placement fixture, and it is very easy to cause the lead wire on the spring coil to be bent and damaged; on the other hand, the corresponding material picking robot needs to be equipped with a special visual system, which increases the procurement cost of the robot and its control difficulty. Therefore, technical personnel are urgently needed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a spring coil transfer mechanism which has a simple structural design, is easy to manufacture and implement, and ensures that the spring coil is kept in the correct position and posture, and ensures that the subsequent material removal operation is smoothly performed.

[0005] In order to solve the above technical problems, the present invention relates to a spring coil transfer mechanism, which is used in conjunction with a spring machine, and includes a support frame, a guide assembly, a linear motion element, a transition piece, a force transmission plate, and a coil positioning assembly. The support frame is fixed on the spring machine. The guide assembly includes a slider, a slide rail, and a slide rail mounting plate. The slide rail is fixed on the slide rail mounting plate, and the whole is supported by the support frame. The coil positioning assembly is used to position the spring coil and is fixed on the upper plane of the transition piece. The transition piece is fixed to the slider. The force transmission plate is fixed on the side wall of the transition piece, and under the driving force of the linear motion element, the coil positioning assembly is driven to perform directional sliding movement along the slide rail. The coil positioning assembly includes a base, a coil positioning column, and a lead positioning plate. A mounting hole extends downward from the top wall of the base. The coil positioning column is inserted and assembled in the mounting hole in a transition fit manner. The lead positioning plate is fixed on the side wall of the base, and two parallel lead passing grooves are opened thereon.

[0006] As a further improvement of the technical solution of the present invention, the lead positioning plate is detachably connected to the base, and its relative height position can be adjusted relative to the base.

Correspondingly, a first threaded hole compatible with the above-mentioned first locking screw is opened on the side wall of the base, and a first waist-shaped hole for the above-mentioned first locking screw to pass through is opened on the lead positioning plate.

[0008] As a further improvement of the technical solution of the present invention, the coil positioning assembly further includes a second locking screw, and correspondingly, a second threaded hole is provided on the side wall of the base, the second threaded hole is adapted to the second locking screw and is connected to the above-mentioned mounting hole.

[0009] As a further improvement of the technical solution of the present invention, the coil positioning assembly further includes an elastic member, which is built into the mounting hole and elastically pressed against the bottom of the coil positioning column.

[0010] As a further improvement of the technical solution of the present invention, the above-mentioned support frame includes a load-bearing plate, a first support vertical plate and a second support vertical plate. The first support vertical plate and the second support vertical plate are both fixed to the load-bearing plate and are used to cooperate in supporting the above-mentioned slide rail mounting plate. The load-bearing plate is detachably fixed to the spring machine by means of a third locking screw. Correspondingly, a second waist-shaped hole, a third waist-shaped hole and a fourth waist-shaped hole are provided on the load-bearing plate for the above-mentioned third locking screw to pass through. The reverse extension lines of the second waist-shaped hole, the third waist-shaped hole and the fourth waist-shaped hole intersect, and a third threaded hole adapted to the third locking screw is provided on the spring machine.

[0011] As a further improvement of the technical solution of the present invention, the first support vertical plate is detachably connected to the load-bearing plate by means of a fourth locking screw. Correspondingly, a fifth waist-shaped hole for the fourth locking screw to pass through is provided on the first support vertical plate, and a fourth threaded hole matched with the fourth locking screw is provided on one side of the load-bearing plate; the second support vertical plate is detachably connected to the load-bearing plate by means of a fifth locking screw. Correspondingly, a sixth waist-shaped hole for the fifth locking screw to pass through is provided on the second support vertical plate, and a fifth threaded hole matched with the fifth locking screw is provided on the other side of the load-bearing plate.

[0012] As a further improvement of the technical solution of the present invention, the support frame also includes a first height adjustment block and a second height adjustment block. The first height adjustment block and the second height adjustment block can be detachably fixed to the bottom wall of the slide rail mounting plate, and can be detachably fixed to the first support vertical plate and the second support vertical plate respectively by means of a sixth locking screw and a seventh locking screw.

DETAILED DESCRIPTION

[0031] 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.

[0032] Figure 3 The schematic diagram shows the installation position of the spring coil transfer mechanism relative to the spring machine in the present invention, which is arranged in front of the spring machine to facilitate the transfer of the formed spring coil to a position convenient for material removal.

[0033] In order to facilitate those skilled in the art to fully understand the technical solutions disclosed in the present invention, the present invention is further described in detail below in conjunction with specific embodiments. Figure 4 , Figure 5 The three-dimensional schematic diagram of the spring coil transfer mechanism of the present invention and its partial enlarged diagram II are respectively shown. It can be seen that it is mainly composed of a support frame 1, a guide assembly 2, a cylinder 3, a transition piece 4, a force transmission plate 5 and a coil positioning assembly 6. Among them, the support frame 1 can be detachably fixed on the spring machine. The guide assembly 2 includes a slider 21, a slide rail 22 and a slide rail mounting plate 23 (such as Figure 8As shown in ). The slide rail 22 is detachably fixed to the slide rail mounting plate 23, and the whole is supported and fixed by the above-mentioned support frame 1. The coil positioning assembly 6 is used to position the spring coil, and is fixed on the upper plane of the transition piece 4. The transition piece 4 and the slider 21 are detachably connected and fixed. The force transmission plate 5 is fixed to the side wall of the transition piece 4, and under the driving force of the cylinder 3, the coil positioning assembly 6 is driven to perform directional sliding movement along the slide rail 22. The coil positioning group 6 includes a base 61, a coil positioning column 62 and a lead positioning plate 63 (as shown in Fig. 9 , 12 , 13, and 14). A mounting hole 611 extends downward from the top wall of the base 61 (as shown in FIG. Fig.12 The coil positioning post 62 is inserted and assembled in the mounting hole 611 in a transition fit manner. The lead positioning plate 63 is fixed to the side wall of the base 61 and has two parallel lead passing grooves 631 (as shown in FIG. Fig.10 , 11 As shown in ). In this way, the existence of the lead positioning plate 63 can limit the position of the lead of the spring coil, prevent it from rotating during the subsequent transfer process, and ensure that it always maintains a correct posture, which is conducive to the subsequent material picking operation of the manipulator. In addition, it is also convenient for workers to replace the coil positioning column 62 of a suitable size in real time, conveniently and quickly according to the shape of the pre-transferred batch of spring coils, thereby expanding the application range of the spring coil transfer mechanism without the need for large-scale modification and design of the spring coil transfer mechanism.

[0034] As a further optimization of the spring coil transfer mechanism structure, the lead positioning plate 63 is preferably detachable to achieve connection with the base 61 (eg Figure 5 As shown in ). In this way, on the one hand, it is convenient to select a suitable lead wire positioning plate 63 according to the lead wire opening size of the specific spring coil to be transferred, thereby reducing the difficulty of the modified design of the spring coil transfer mechanism.

[0035] In order to facilitate and operate the relative height adjustment of the lead wire positioning plate 63 and ensure that the lead wire of the spring coil is well limited, the coil positioning assembly 6 can also be optimized as follows: the coil positioning assembly 6 is additionally provided with a first locking screw (not shown in the figure), and correspondingly, a first threaded hole 612 adapted to the first locking screw is provided on the side wall of the base 61, and a first waist-shaped hole 632 (such as a hole 632) for the first locking screw to pass through is provided on the lead wire positioning plate 63. Figure 5 , 9, 14). In the process of debugging the spring coil transfer mechanism, first loosen the first locking screw, then push the lead positioning plate 63 to move upward or downward until the lead of the spring coil is completely placed in the lead passing groove 631, and then re-tighten the first locking screw.

[0036] Generally speaking, the thickness of the spring coil will also change according to different customer design requirements. When the thickness of the preloaded spring coil changes significantly, the worker is required to pull out or press down the coil positioning column 62 for a certain length, during which it slides relative to the mounting hole 611. In order to ensure the position stability of the coil positioning column 62 and prevent it from subsequently changing its position due to impact loads, as a further optimization of the above technical solution, the coil positioning assembly 6 can also be provided with a second locking screw (not shown in the figure) according to actual conditions, and correspondingly, a second threaded hole 613 is opened on the side wall of the base 61. The second threaded hole 613 is adapted to the second locking screw and is connected to the above-mentioned mounting hole 611 (such as Fig.10 ). When the relative height of the pressure coil positioning column 62 is adjusted to the right position, the first locking screw is immediately tightened until it presses against the side wall of the pressure coil positioning column 62. However, it should be noted that, for the purpose of preventing loosening, the first locking screw needs to be equipped with an anti-loosening gasket to prevent it from loosening due to the exciting force in the later stage.

[0037] In order to ensure the convenience of workers adjusting the posture of the support frame 1 according to the specific situation, and then ensure that the coil positioning assembly 6 occupies the correct position relative to the spring machine, so as to facilitate the subsequent transfer of the spring coil from the spring machine to the coil positioning assembly 6, such as Figure 6 , 7 As shown in , the support frame 1 is preferably composed of several parts such as a bearing plate 11, a first supporting vertical plate 12 and a second supporting vertical plate 13. Among them, the first supporting vertical plate 12 and the second supporting vertical plate 13 are fixed to the upper plane of the bearing plate 11, and are used to support the above-mentioned slide rail mounting plate 23. The bearing plate 11 is detachably fixed to the spring machine by means of a third locking screw (not shown in the figure). Correspondingly, a second waist-shaped hole 111, a third waist-shaped hole 112, and a fourth waist-shaped hole 113 are provided on the bearing plate 11 for the above-mentioned third locking screw to pass through. The reverse extension lines of the second waist-shaped hole 111, the third waist-shaped hole 112, and the fourth waist-shaped hole 113 intersect, and a third threaded hole (not shown in the figure) adapted to the third locking screw is provided on the spring machine. In this way, it is convenient for workers to adjust the swing angle of the support frame 1 itself along the left and right directions according to specific conditions, thereby realizing the adjustment of the posture of the coil positioning assembly 6.

[0038] Furthermore, as a further optimization of the above technical solution, the first support vertical plate 12 and the load-bearing plate 11 are preferably fixed in a detachable manner, and the specific recommended solution is as follows: the first support vertical plate 12 is fixedly connected to the load-bearing plate 11 by means of a fourth locking screw (not shown in the figure), and correspondingly, a fifth waist-shaped hole 121 for the fourth locking screw to pass through is opened on the first support vertical plate 12, and a fourth threaded hole 114 compatible with the fourth locking screw is opened on one side of the load-bearing plate 11; and the second support vertical plate 13 and the load-bearing plate 11 are also preferably fixed in a detachable manner, and the specific recommended solution is as follows: the second support vertical plate 13 is fixedly connected to the load-bearing plate 11 by means of a fifth locking screw (not shown in the figure), and correspondingly, a sixth waist-shaped hole 131 for the fifth locking screw to pass through is opened on the second support vertical plate 13, and a fifth threaded hole 115 compatible with the fifth locking screw is opened on the other side of the load-bearing plate 11 (as shown in the figure Figure 6 , 7 In this way, it is convenient for workers to adjust the inclination angle of the support frame 1 along the front-back direction according to specific conditions, thereby achieving the adjustment of the posture of the coil positioning assembly 6.

[0039] Furthermore, as a further optimization of the above technical solution, the support frame 1 is preferably additionally provided with a first height adjustment block 14 and a second height adjustment block 15. The first height adjustment block 14 and the second height adjustment block 15 can be detachably fixed to the bottom wall of the slide rail mounting plate 23, and can be detachably fixed to the first support vertical plate 12 and the second support vertical plate 13 respectively by means of a sixth locking screw (not shown in the figure) and a seventh locking screw (not shown in the figure). A seventh waist-shaped hole 122 is provided on the first support vertical plate 12 for the sixth locking screw to pass through, and a sixth threaded hole 141 matched with the sixth locking screw is provided on the first height adjustment block 14. An eighth waist-shaped hole 132 is provided on the second support vertical plate 13 for the seventh locking screw to pass through, and a seventh threaded hole 151 (as shown in the figure) matched with the seventh locking screw is provided on the second height adjustment block 15. Figure 6 In this way, it is convenient for workers to adjust the relative height position of the coil positioning assembly 6 according to specific conditions, thereby achieving adjustment of the posture of the coil positioning assembly 6.

[0040] Fig.15The schematic diagram of the structure of the base in the second embodiment of the coil positioning assembly of the present invention is shown. The difference between the second embodiment and the first embodiment is that the coil positioning assembly 6 is additionally provided with a columnar spring 64. The columnar spring 64 is built into the mounting hole 611 and is elastically pressed against the bottom of the coil positioning column 62. In this way, the coil positioning column 62 is always subjected to the elastic pressing force, and the coil positioning column 62 can be easily pulled out of the mounting hole 611 manually without the aid of tools, thereby reducing the difficulty of operation.

[0041] It should be noted that, in addition to the above-mentioned columnar spring 64, other elastic members, such as a columnar rubber body, may also be selected according to actual conditions and design requirements.

[0042] 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.
