Obviously, the described embodiments only constitute some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art based on the present application belong to the scope of protection of the present application.
[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. The support frame 11, the first fixing mechanism 12, the second fixing mechanism 13, the first adjusting mechanism 14, the first threaded rod 141, the first fixed seat 142, the first threaded seat 143, the first rotating hand wheel 144, the first locking piece 145, the first locking rod 146, the first locking handle 147, the third threaded rod 148, the third fixed seat 149, the third threaded seat 1410, the third rotating hand wheel 1411, the scissor adjusting member 1412, and the third horizontal seat 1413 are provided.
[0030] The existing template ball planting method completely relies on manual operation. The error of manual operation (for example, the position offset of MLO and template due to shaking) inevitably affects the tin ball planting effect. Especially, with the decrease of the pad spacing on MLO and the increase of the pad density, the influence of pure manual alignment operation on the tin ball planting precision gradually deepens. In order to improve the alignment precision of the template and MLO pad in the MLO tin ball planting process, for example, Figure 1The tin ball implantation alignment device is shown in the utility model embodiment.
[0031] The tin ball implantation alignment device can include a support frame, a first fixing mechanism, a second fixing mechanism, a first adjusting mechanism, a second adjusting mechanism, and a third adjusting mechanism.
[0032] The first fixing mechanism is fixed on the top support plate on the upside of the support frame and is used for fixing the tin ball implantation template.
[0033] In the utility model embodiment, an operation window is formed on the top support plate, and the first fixing mechanism is arranged in parallel on both sides of the operation window. Thus, the operator can place the tin ball implantation template at the operation window position and fix the tin ball implantation template on the top support plate by using the first fixing mechanism. In actual application, the tin ball implantation template can also be referred to as a steel mesh.
[0034] The first adjusting mechanism is fixed on the upside of the base of the support frame and is used for adjusting the position of the tin ball MLO to be implanted.
[0035] In the embodiment, the first adjusting mechanism can include an X-direction adjusting member, a Y-direction adjusting member, and a Z-direction adjusting member. The X-direction adjusting member is used for adjusting the position of the tin ball MLO to be implanted along the X-axis direction. The Y-direction adjusting member is used for adjusting the position of the tin ball MLO to be implanted along the Y-axis direction. The Z-direction adjusting member is used for adjusting the position of the tin ball MLO to be implanted along the Z-axis direction.
[0036] The Y-direction adjusting member can include a first threaded rod, a first fixing seat, a first threaded seat, and a first rotating hand wheel. As shown in the figure, Figure 2 The first threaded rod is connected with the first rotating hand wheel at one end, and the other end of the first threaded rod is rotationally connected with the first fixing seat. The first rotating hand wheel is used for controlling the rotation of the first threaded rod. The first threaded seat is provided with a first threaded through hole, and the first threaded seat is sleeved on the first threaded rod through the first threaded through hole and is threadedly connected with the first threaded rod. The bottom of the first threaded seat is slidingly connected with the first fixing seat. Thus, the operator can rotate the first rotating hand wheel to rotate the first threaded rod, the first threaded seat sleeved on the first threaded rod is driven to slide along the first fixing seat, and thus the position adjustment along the Y-axis direction is realized.
[0037] In order to avoid the position change caused by operation errors and the like after the position adjustment, in an implementable manner, the Y-direction adjusting member can further include a first locking piece for controlling the rotation state of the first threaded rod. The first locking piece includes a first locking piece, a first locking rod, and a first locking handle. The first locking piece is of a single-sided opening shape and is provided with a first locking through hole in the vertical opening direction. The first locking rod is sleeved in the first locking through hole, one end of the first locking rod is clamped with the first locking piece, and the other end is threadedly connected with the first locking handle. As shown in the figure, Figure 3As shown, one end of the first locking rod is clamped with the first locking sheet, and the other end, that is, the end of the first locking rod extending out of the first locking through hole, is threadedly connected with the first locking handle; the first locking member is fixed on the first fixed seat through the first locking sheet and is sleeved with the first threaded rod. Thus, the first threaded rod is locked and cannot rotate by rotating the first locking handle, and the first threaded rod is released and can rotate by loosening the first locking handle, so that the rotation state of the first threaded rod is controlled. Then, the operator can realize position fixing after position adjustment through the first locking mechanism, so as to ensure the alignment accuracy and improve the effect of soldering balls.
[0038] The X-direction adjusting member can include a second threaded rod, a second fixed seat, a second threaded seat and a second rotating handle. One end of the second threaded rod is connected with the second rotating handle, and the second rotating handle is used for controlling the rotation of the second threaded rod; the other end of the second threaded rod is rotationally connected with the second fixed seat; the second threaded seat is sleeved on the second threaded rod and is threadedly connected with the second threaded rod; and the bottom of the second threaded seat is slidingly connected with the second fixed seat. Thus, the operator can rotate the second rotating handle to rotate the second threaded rod, the second threaded seat sleeved on the second threaded rod is driven to slide along the second fixed seat by the rotation of the second threaded rod, and then the position adjustment in the X-axis direction is realized.
[0039] In the embodiment of the utility model, to avoid the position change caused by operation failure and the like after position adjustment, the X-direction adjusting member can further include a second locking member. The second locking member is used for controlling the rotation state of the second threaded rod in the X-direction adjusting member. The second locking member includes a second locking sheet, a second locking rod and a second locking handle. The second locking rod is sleeved in the second locking through hole in the direction perpendicular to the opening of the second locking sheet, and the second locking handle is threadedly connected with the part of the second locking rod extending out of the second locking through hole. The second locking member is fixed on the second fixed seat through the second locking sheet and is sleeved with the second threaded rod, and is used for making the second threaded rod non-rotatable by tightening the second locking handle.
[0040] In the embodiment of the utility model, the X-direction adjusting member and the Y-direction adjusting member can be members with the same structure, that is, two same position adjusting members can be arranged perpendicularly to each other to realize the position adjustment in different directions (X-axis direction and Y-axis direction). That is, in the embodiment of the utility model, the first threaded rod of the Y-direction adjusting member is perpendicular to the second threaded rod of the X-direction adjusting member, so as to realize the position adjustment in the X-axis direction and the Y-axis direction.
[0041] The second locking member and the first locking member can have the same structure, and the description of the second locking member can refer to the first locking member, which will not be described herein.
[0042] As Figure 4As shown, the Z-direction adjusting member comprises a third threaded rod, a third fixed seat, a third threaded seat, a third rotating hand wheel and a scissors adjusting piece; one end of the third threaded rod is connected with the third rotating hand wheel, and the third rotating hand wheel is used for controlling the rotation of the third threaded rod; the other end of the third threaded rod is sleeved with a third threaded slider and is threadedly connected with the third threaded rod; the bottom of the third threaded slider is slidably connected with the third fixed seat. An operator can rotate the third rotating hand wheel to rotate the third threaded rod, and the third threaded rod rotates to drive the third threaded slider sleeved on the third threaded rod to slide along the third fixed seat. The first lower fork leg of the scissors adjusting piece is fixed on the third fixed seat, and the second lower fork leg is fixed on the third threaded slider; thus, during the sliding of the third threaded slider along the third fixed seat, the distance between the first lower fork leg and the second lower fork leg changes, the height of the Z-direction adjusting member increases when the distance decreases, and the height of the Z-direction adjusting member decreases when the distance increases, so as to complete the adjustment of the Z-direction position.
[0043] In an implementable manner, the Z-direction adjusting member can further comprise a third horizontal seat, the first upper fork leg of the scissors adjusting piece is fixed on the third horizontal seat, and the second upper fork leg of the scissors adjusting piece is fixed on the third slider; the third slider is sleeved on a sliding rod on the third horizontal seat, and the top surface of the third slider is slidably connected with the third horizontal seat. The first upper fork leg and the second lower fork leg are located on the same arm, and the second upper fork leg and the first lower fork leg are located on the same arm. Thus, the remaining mechanisms or members can be stably fixed with the Z-direction adjusting member through the third horizontal seat.
[0044] In an implementable manner, the first adjusting mechanism can sequentially comprise, from top to bottom, the Z-direction adjusting member, the X-direction adjusting member and the Y-direction adjusting member; at this time, the first fixed seat can be fixed on the upper side of the bottom of the support frame; the second fixed seat can be fixed on the first threaded seat; and the third fixed seat can be fixed on the second threaded seat. In the embodiment of the utility model, the relative positions of the X-direction adjusting member, the Y-direction adjusting member and the Z-direction adjusting member from top to bottom are not fixed, and can be adjusted according to actual use conditions, and the remaining positional relationships are not described herein.
[0045] In this way, the position of the to-be-planted solder ball MLO is adjusted from the X, Y and Z directions through the first adjusting mechanism, and the rotation of the hand wheel combined with the threaded structure can effectively improve the adjustment precision, avoid the manual alignment process, align the pad position on the to-be-planted solder ball MLO with the hole position of the solder ball template with high precision, and further improve the soldering precision in the subsequent soldering process and improve the soldering quality.
[0046] The second adjusting mechanism is fixed on the side of the first adjusting mechanism away from the base, and in the embodiment, when the first adjusting mechanism is sequentially provided with the Z-direction adjusting member, the X-direction adjusting member and the Y-direction adjusting member from top to bottom, the second adjusting mechanism can be fixed on the third horizontal base to realize the relative fixation of the first adjusting mechanism and the second adjusting mechanism.
[0047] In an implementable manner, the second adjusting mechanism can include concentric rotating discs, and the concentric rotating discs can include an upper rotating disc and a lower rotating disc, the side of the lower rotating disc can be marked with a rotation angle, and the side of the upper rotating disc can be marked with a reference line, so that the rotation angle can be conveniently observed by the operator during rotation.
[0048] The third adjusting mechanism is fixed on the side of the second adjusting mechanism away from the first adjusting mechanism, and when the second adjusting mechanism is the concentric rotating disc, the third adjusting mechanism can be fixed on the upper rotating disc.
[0049] In the embodiment of the utility model, the third adjusting mechanism can include an X-direction rotating member and a Y-direction rotating member; the X-direction rotating member is used for controlling the rotation angle of the to-be-planted solder ball MLO around the X axis; and the Y-direction rotating member is used for controlling the rotation angle of the to-be-planted solder ball MLO around the Y axis.
[0050] In the embodiment, the X-direction rotating member and the Y-direction rotating member can be rotating members of the same structure, and the rotation axes of the two rotating members are perpendicular to each other, so that the third adjusting mechanism capable of controlling the rotation of the to-be-planted solder ball MLO around the X axis and the Y axis is obtained.
[0051] In an implementable manner, the X-direction rotating member can be fixed on the side of the second adjusting mechanism away from the first adjusting mechanism; and the Y-direction rotating member can be fixed on the side of the X-direction rotating member away from the second adjusting mechanism.
[0052] In another implementable manner, the Y-direction rotating member can be fixed on the side of the second adjusting mechanism away from the first adjusting mechanism; and the X-direction rotating member can be fixed on the side of the X-direction rotating member away from the second adjusting mechanism.
[0053] In this way, the third adjusting mechanism is used to adjust the offset angle of the to-be-planted solder ball MLO relative to the horizontal plane, so that the to-be-planted solder ball MLO can be better matched with the solder ball template, thereby improving the subsequent soldering effect.
[0054] The second fixing mechanism is fixed on the third adjusting mechanism away from the second adjusting mechanism, and is used for fixing the to-be-placed solder ball MLO.
[0055] Working principle: when placing the solder ball on the MLO, the operator can first fix the to-be-placed solder ball MLO on the solder ball placement device provided by the embodiment of the utility model through the second fixing mechanism, wherein the Pad (pad) requiring the solder ball is upward; and then fix the solder ball template corresponding to the to-be-placed solder ball MLO on the solder ball placement device through the second fixing mechanism. Meanwhile, in order to improve the subsequent alignment efficiency, the solder ball template and the to-be-placed solder ball MLO can be pre-aligned based on the position of the Pad of the to-be-placed solder ball MLO and the position of the hole of the solder ball template, and then the solder ball template is fixed. The operator aligns the position of the Pad of the to-be-placed solder ball MLO with the position of the hole of the solder ball template through the first rotating hand wheel and / or the second rotating hand wheel and / or the third rotating hand wheel and / or the second adjusting mechanism and / or the X-direction rotating component and / or the Y-direction rotating component.
[0056] Moreover, after the operator moves the to-be-placed solder ball MLO to the appropriate X-direction position and Y-direction position, the operator can lock the X-direction adjusting component and the Y-direction adjusting component by using the locking piece (the first locking piece and the second locking piece), so as to ensure that the X-direction position and the Y-direction position of the to-be-placed solder ball MLO do not change. The operator can fix the locking rod of the locking piece by using a tool such as a screwdriver, and simultaneously tighten the locking handle, so that the locking handle presses the locking sheet downward, and then the locking sheet clamps the threaded rod inward, thereby completing the locking of the X-direction adjusting component and the Y-direction adjusting component. Conversely, when the operator needs to adjust the X-direction position and the Y-direction position of the to-be-placed solder ball MLO, the operator can fix the locking rod of the locking piece by using a tool such as a screwdriver, and simultaneously loosen the locking handle, so as to release the locking sheet, and then the threaded rod can be rotated, thereby adjusting the X-direction position and the Y-direction position of the to-be-placed solder ball MLO.
[0057] Furthermore, after the to-be-placed solder ball MLO is aligned with the solder ball template, the operator can uniformly apply solder paste to the area of the to-be-placed solder ball MLO by using a scraper, and then wipe off the excess solder paste, and then heat the solder ball by using an air gun, and then brush off the excess solder ball, so as to complete the high-precision placement of the solder ball on each Pad of the MLO.
[0058] The solder ball placement device provided by the embodiment of the utility model can be used for adjusting the position of the to-be-placed solder ball MLO through the first adjusting mechanism, adjusting the rotation angle of the to-be-placed solder ball MLO around the Z axis through the second adjusting mechanism, and adjusting the inclination angle of the to-be-placed solder ball MLO relative to the horizontal plane through the third adjusting mechanism, so that the position of the Pad on the to-be-placed solder ball MLO after adjustment is high-precision aligned with the hole of the template, the pure manual operation error is reduced, and the alignment precision of the template and the Pad of the MLO in the process of placing the solder ball on the MLO is improved. Furthermore, in the subsequent process of placing the solder ball, the precision of placing the solder ball and the product quality are improved.
