[0028] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0029] See also Figures 1 to 10 As shown, it is an embodiment of the present invention. Figures 1 to 5 As shown, this embodiment discloses a facing multi-axis operation device 100, which can be used to perform a preset operation, and the preset operation can be adjusted and changed according to design requirements. For example, the facing multi-axis operation device 100 in the drawings of this embodiment is described by being matched with a chip supply station 200 to perform a die bonding operation, but in other embodiments not shown in the present invention, the facing multi-axis operation device 100 can also be used to perform a die extraction operation or a detection operation according to design requirements.

[0030] like Figures 2 to 4 As shown, the opposing multi-axis operating equipment 100 in this embodiment includes a first operating mechanism 1, a second operating mechanism 2 arranged along a spacing direction Ds and spaced from the first operating mechanism 1, an indicator 3 (spaced) between the first operating mechanism 1 and the second operating mechanism 2, and a correction mechanism 4 arranged corresponding to the indicator 3, but the present invention is not limited thereto.

[0031] For example, in other embodiments not shown in the present invention, the correction mechanism 4 can be omitted or replaced by other components according to design requirements. In addition, the spacing direction Ds is described as a plumb direction in this embodiment, but the present invention is not limited thereto. The following will first introduce the specific structure of each mechanism included in the opposing multi-axis operation device 100 in this embodiment, and then explain the connection relationship between the multiple mechanisms in due course.

[0032] The first operating mechanism 1 includes a first rail 11 and a carrier 12 mounted on the first rail 11. The first rail 11 is, for example, a linear slide rail, which is straight and parallel to a first direction D1 perpendicular to the spacing direction Ds, but is not limited thereto. The carrier 12 is used to place a target object O (such as a chip carrier), and the carrier 12 can move relative to the first rail 11 along the first direction D1.

[0033] In more detail, the carrier 12 in this embodiment includes a bottom plate 121, a top plate 122 spaced from the bottom plate 121 along the spacing direction Ds, a plurality of fine-tuning members 123 clamped and connected between the bottom plate 121 and the top plate 122, and a plurality of first position sensors 124 disposed on the top plate 122, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the structure formed by the bottom plate 121, the top plate 122, and the plurality of fine-tuning members 123 can be adjusted, changed, or omitted according to design requirements, and the number of the plurality of first position sensors 124 can be at least one.

[0034] In this embodiment, the bottom plate 121 is movably disposed on the first track 11 along the first direction D1, and the relative position between the bottom plate 121 and the top plate 122 can be adjusted by a plurality of the fine-tuning members 123. For example, the plurality of the fine-tuning members 123 can have different lengths in the spacing direction Ds, thereby effectively adjusting the horizontality of the top plate 122 relative to the bottom plate 121.

[0035] Furthermore, the top surface of the top plate 122 is used for setting the target object O, and the plurality of first position sensors 124 are configured on the top surface of the top plate 122 and located around the target object O, so as to facilitate the plurality of first position sensors 124 to detect and operate in conjunction with the indicator 3.

[0036] In more detail, the plurality of first position sensors 124 include a plurality of first XY axis sensors 1241 and a plurality of first Z axis sensors 1242. The plurality of first XY axis sensors 1241 may be arranged along a second direction D2 perpendicular to the spacing direction Ds and the first direction D1, and thus respectively located on opposite sides of the target object O. The plurality of first Z axis sensors 1242 are respectively arranged in two rows parallel to the first direction D1 with the plurality of first XY axis sensors 1241, and the plurality of first Z axis sensors 1242 are preferably arranged corresponding to the position configuration of the plurality of fine adjustment members 123, so as to provide the sensing data required for the operation of the plurality of fine adjustment members 123 more accurately.

[0037] It should be additionally explained that, although the second direction D2 is described as being perpendicular to the first direction D1 in this embodiment, the second direction D2 may also be non-parallel to the first direction D1.

[0038] The second operating mechanism 2 includes a second rail 21 and a working component 22 mounted on the second rail 21. The second rail 21 is, for example, a linear slide rail, which is straight and parallel to the second direction D2, but the present invention is not limited thereto. The working component 22 can move relative to the second rail 21 along the second direction D2.

[0039] The working part 22 in this embodiment includes an annular plate 221, an acquisition device 222 movably disposed in the annular plate 221, and a plurality of second position sensors 223 disposed on the annular plate 221, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the number of the plurality of second position sensors 223 can be at least one; or, the acquisition device 222 can be adjusted and changed according to design requirements (e.g., when the opposing multi-axis operation device 100 is used to perform the detection operation, the acquisition device 222 can be replaced by a camera).

[0040] In this embodiment, the annular plate 221 is movably disposed on the second track 21 along the second direction D2, and the annular plate 221 can drive the acquirer 222 to move along the second direction D2, and the acquirer 222 can also move along the spacing direction Ds relative to the annular plate 221. Furthermore, a plurality of second position sensors 223 are disposed on the bottom surface of the annular plate 221 and are located around the acquirer 222.

[0041] In more detail, the plurality of second position sensors 223 include a plurality of second XY axis sensors 2231 and a plurality of second Z axis sensors 2232. The plurality of second XY axis sensors 2231 may be arranged along the first direction D1, and thus respectively located on opposite sides of the acquirer 222. The plurality of second Z axis sensors 2232 are respectively arranged with the plurality of second XY axis sensors 2231 in two rows parallel to the second direction D2, so as to more accurately provide the sensing data required for the operation of the acquirer 222.

[0042] The indicator 3 includes a carrier 33 and a first scale 31 and a second scale 32 located on opposite sides of the carrier 33. It should be noted that the first scale 31 and the second scale 32 can be integrally formed on the carrier 33 to form a single-piece structure (for example, the first scale 31 and the second scale 32 can also be engraved on the surface of the carrier 33); or, the first scale 31 and the second scale 32 can be additionally processed or installed on the carrier 33, and the present invention is not limited here.

[0043] More specifically, the carrier 33 in this embodiment is plate-shaped and has a first plate surface 331 and a second plate surface 332 located on opposite sides thereof, and the carrier 33 is formed with a through-shaped operation window 333, and the first scale 31 is located on the first plate surface 331, and the second scale 32 is located on the second plate surface 332, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, when the opposing multi-axis operation device 100 is used to perform the detection operation, the operation window 333 can be a transparent plate instead of a through-shaped one.

[0044] In this embodiment, the first scale 31 and the second scale 32 are two linear encoders 311 and 321, such as an optical ruler. The two linear encoders 311 of the first scale 31 are parallel to the first direction D1 and are arranged on opposite sides of the operation window 333 along the second direction D2. Furthermore, the two linear encoders 321 of the second scale 32 are parallel to the second direction D2 and are arranged on opposite sides of the operation window 333 along the first direction D1.

[0045] In more detail, each of the first position sensors 124 faces the first scale 31 along the spacing direction Ds, and each of the first position sensors 124 is separated from the first scale 31 by a first sensing distance S1 along the spacing direction Ds. In other words, when the carrier 12 moves relative to the first track 11 along the first direction D1 so that each of the first position sensors 124 moves along a first path, a first projection area formed by the positive projection of the first path along the spacing direction Ds onto the carrier 33 overlaps with the first scale 31.

[0046] Furthermore, each of the second position sensors 223 faces the second scale 32 along the spacing direction Ds, and the second position sensor 223 and the second scale 32 are separated by a second sensing distance S2 along the spacing direction Ds. The first sensing distance S1 is preferably 90% to 110% of the second sensing distance S2. In other words, when the working member 22 moves relative to the second track 21 along the second direction D2, so that each of the second position sensors 223 moves along a second path, and a second projection area formed by the positive projection of the second path on the carrier 33 along the spacing direction Ds overlaps with the second scale 32.

[0047] In addition, the working part 22 of the second working mechanism 2 faces the target object O disposed on the first working mechanism 1 along the spacing direction Ds through the working window 333 of the indicator 3. In order to facilitate the facing multi-axis working device 100 to perform the preset operation relative to the target object O, the working window 333 preferably meets at least some of the following conditions.

[0048] The operation window 333 has a width W333 corresponding to the first direction D1 and a length L333 corresponding to the second direction D2. The length L333 of the operation window 333 is not less than the outer diameter R2 of the target object O in the second direction D2, and the width W333 of the operation window 333 is less than the outer diameter R1 of the target object O in the first direction D1 and there is a difference therebetween.

[0049] Furthermore, the supporting platform 12 can move a first stroke not less than the difference along the first direction D1, and the working component 22 can move a second stroke along the second direction D2, so as to facilitate the movement of the supporting platform 12 and the working component 22 in combination with the specific size configuration of the working window 333, so that the working component 22 can perform the preset operation corresponding to any area of ​​the target object O.

[0050] It should be additionally explained that, in order to enable the opposing multi-axis operating device 100 to have higher operating accuracy, the first sensing distance S1 is preferably less than 50% of the first stroke, and the second sensing distance S2 is preferably less than 50% of the second stroke, but the present invention is not limited thereto.

[0051] As described above, when the opposed multi-axis operation device 100 performs the preset operation (such as the die bonding operation, the die extraction operation or the detection operation), the carrier 12 and the working component 22 can confirm their real-time positions through the first position sensor 124 and the second position sensor 223, respectively, by the first scale 31 and the second scale 32 of the indicator 3, so that the working component 22 can implement a preset step (such as: Figure 7 and Figure 8 ).

[0052] Accordingly, in the present embodiment, the opposing multi-axis operating equipment 100 has the indicator 3 as a fixed part disposed between the first operating mechanism 1 and the second operating mechanism 2, so as to effectively reduce the distance between the first operating mechanism 1 and the second operating mechanism 2 relative to the alignment reference (that is, the indicator 3), thereby reducing the possible tolerance to meet higher operating accuracy requirements.

[0053] Furthermore, when the preset operation is the die bonding operation, the opposing multi-axis operation device 100 preferably further uses the calibration mechanism 4 to cooperate with the working component 22 to adjust or confirm the relative position between the acquirer 222 and the acquired chip 201 (e.g.: Figure 6 ).

[0054] like Figures 2 to 4 As shown, the calibration mechanism 4 in this embodiment is arranged along the second direction D2 with the operation window 333 and is located between the two linear encoders 321 of the second scale 32. The carrier 33 has a detection window 334 formed on one side of the operation window 333, and the calibration mechanism 4 is installed on the detection window 334.

[0055] Accordingly, the working component 22 can be used to obtain a chip 201 from the chip supply station 200 located outside the first operating mechanism 1 (eg: Figure 5 ), and the working part 22 can confirm the position of the chip 201 obtained by the calibration mechanism 4 (such as: Figure 6 ), and then in the preset operation, the chip 201 is placed on the preset area of ​​the target object O along the spacing direction Ds through the operation window 333 (eg: Figure 7 and Figure 8 ).

[0056] In addition, if Fig. 9 and Fig.10As shown, the opposing multi-axis operation device 100 can then perform another preset operation; that is, the working component 22 can be used to obtain another chip 201 from the chip supply table 200, and the working component 22 can confirm the position of the other chip 201 it has obtained through the correction mechanism 4, and then pass the chip 201 through the operation window 333 and set it on another preset area of ​​the target object O.

[0057] [Technical Effects of Embodiments of the Invention]

[0058] To summarize, the opposing multi-axis operating equipment disclosed in the embodiment of the present invention, by providing the indicator as a fixed part between the first operating mechanism and the second operating mechanism, can effectively reduce the distance between the first operating mechanism and the second operating mechanism relative to the alignment reference (that is, the indicator), thereby reducing the possible tolerance to meet higher operating accuracy requirements.
