[0002] The adhesive bonding process in die bonders requires a dispensing mechanism to precisely apply adhesive to predetermined locations on the chip to ensure good chip fixation in subsequent bonding steps. Existing dispensing mechanisms typically use only a single dispensing head, resulting in low dispensing efficiency; therefore, this problem needs to be addressed. Utility Model Content

[0003] In view of this, the present invention provides a linear motor dispensing mechanism, which can solve the technical problem that the dispensing mechanism in the prior art dispensing the chip with only a single dispensing head has low dispensing efficiency.

[0004] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0005] An embodiment of this utility model provides a linear motor dispensing mechanism, including a frame, a first linear motor, and a dispensing assembly;

[0006] The dispensing assembly includes a first movable block, a second movable block, a third movable block, a second linear motor, a third linear motor, and a dispensing cylinder. The dispensing cylinder is disposed on the third movable block. The third movable block and the third linear motor are both disposed on the second movable block, and the second movable block and the second linear motor are both disposed on the first movable block. The first movable block and the first linear motor are both disposed on the frame. The second linear motor drives the second movable block to move along the Y direction, and the third linear motor drives the third movable block to move along the Z direction.

[0007] The number of dispensing components is two or more, and each dispensing component is driven by the same first linear motor to move along the X direction through its own first movable block; the X direction, Y direction and Z direction are perpendicular to each other.

[0008] In some embodiments, the linear motor dispensing mechanism further includes an X-axis guide rail, which is used to simultaneously guide the first movable block of each dispensing assembly in the X direction.

[0009] In some embodiments, the number of X-guide rails is two, and they are symmetrically distributed on both sides of the first linear motor.

[0010] In some embodiments, the dispensing assembly further includes a first clamping arm, a second clamping arm, and a bolt. The first clamping arm is fixed to the third movable block. The bolt's thread passes through a through hole in the first clamping arm and is fixedly connected to the second clamping arm. An elastic element is sleeved on the bolt's thread, and the elastic element is located between the bolt's nut and the through hole end face. The elastic element applies force to the bolt's nut, causing the second clamping arm to move closer to the first clamping arm, thereby clamping the dispensing cylinder.

[0011] In some embodiments, the bolt shank is inserted into a connecting hole on the second clamping arm, and the second clamping arm is further provided with a first threaded hole extending through the connecting hole; the dispensing assembly further includes a first screw, which is used to thread into the first threaded hole and to secure the bolt shank within the connecting hole, so that the bolt shank is fixedly connected to the second clamping arm.

[0012] In some embodiments, the second clamping arm is provided with a handle.

[0013] In some embodiments, the third movable block is provided with a positioning hole through which the dispensing head of the dispensing tube passes;

[0014] The third movable block is provided with a sliding groove, and the first clamping arm is provided with a slider that slides in cooperation with the sliding groove. The bottom of the sliding groove is provided with a second threaded hole. The slider is provided with a through waist-shaped hole. The dispensing assembly also includes a second screw, which is used to pass through the waist-shaped hole and be threadedly connected to the second threaded hole.

[0015] By employing the above technical solution, the linear motor dispensing mechanism of this utility model has at least the following beneficial effects:

[0016] 1. The first linear motor of this invention, in conjunction with each dispensing assembly, can drive the dispensing cylinder on each dispensing assembly to move along the X, Y, or Z directions, thereby enabling accurate adjustment of the dispensing cylinder's position. Furthermore, since there are two or more dispensing assemblies, dispensing operations can be performed on two or more chips simultaneously, improving dispensing efficiency.

[0017] 2. Since the movement of each dispensing component along the X direction is driven by the same linear motor, the number of linear motors can be reduced, thus lowering costs.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a linear motor dispensing mechanism, which includes a frame 1, a first linear motor 2, and a dispensing assembly 4. The dispensing assembly 4 includes a first movable block 41, a second movable block 51, a third movable block 44, a second linear motor 42, a third linear motor 43, and a dispensing cylinder 45. The dispensing cylinder 45 is disposed on the third movable block 44, and both the third movable block 44 and the third linear motor 43 are disposed on the second movable block 51. The second movable block 51 and the second linear motor 42 are both disposed on the first movable block 41. The first movable block 41 and the first linear motor 2 are both disposed on the frame 1. The second linear motor 42 drives the second movable block 51 to move along the Y direction, causing the second movable block 51 to move the dispensing cylinder 45 along the Y direction. The third linear motor 43 drives the third movable block 44 to move along the Z direction, causing the third movable block 44 to move the dispensing cylinder 45 along the Z direction.

[0028] The aforementioned dispensing assembly 4 consists of two or more components. Each dispensing assembly 4 is driven by the same first linear motor 2 via its own first movable block 41 to move along the X direction, thereby causing its respective dispensing cylinder 45 to move together along the X direction. The X, Y, and Z directions are all perpendicular to each other.

[0029] In the above example, the first linear motor 2 works in conjunction with each dispensing assembly 4 to drive the dispensing cylinder 45 on each dispensing assembly 4 to move along the X, Y, or Z directions, thereby allowing for accurate adjustment of the position of the dispensing cylinder 45. Furthermore, since there are two or more dispensing assemblies 4, dispensing operations can be performed on two or more chips simultaneously, improving dispensing efficiency.

[0030] In addition, since the movement of each dispensing component 4 along the X direction is driven by the same linear motor, the number of linear motors can be reduced, thus lowering costs.

[0031] In some implementations, such as Figure 1As shown, the aforementioned linear motor dispensing mechanism also includes an X-axis guide rail 3, which is used to simultaneously guide the first movable block 41 of each dispensing component 4 in the X direction, thus saving the number of X-axis guide rails 3 and reducing costs.

[0032] In some implementations, such as Figure 1 As shown, there can be two X-guide rails 3, which are symmetrically distributed on both sides of the first linear motor 2, thereby improving the smoothness of the movement of each dispensing component 4 in the X direction.

[0033] In some implementations, such as Figure 2-3 As shown, the aforementioned dispensing assembly 4 further includes a first clamping arm 46, a second clamping arm 47, and a bolt 49. The first clamping arm 46 is fixed to the aforementioned third movable block 44, and a through hole 462 is provided on the first clamping arm 46. The bolt shank 491 passes through the through hole 462 on the first clamping arm 46 and is fixedly connected to the second clamping arm 47. An elastic element 50 is sleeved on the bolt shank 491, and the elastic element 50 is located between the bolt nut 492 and the end face of the through hole. The elastic element 50 applies force to the bolt nut 492, causing the second clamping arm 47 to move closer to the first clamping arm 46, thereby clamping the dispensing cartridge 45.

[0034] In the above example, the first clamping arm 46 is fixed to the third movable block 44, and the second clamping arm 47 can move closer to or further away from the first clamping arm 46. When it is necessary to install the dispensing cartridge 45, the second clamping arm 47 can be pulled by hand to move it away from the first clamping arm 46, and then the dispensing cartridge 45 can be inserted between the first clamping arm 46 and the second clamping arm 47; then the second clamping arm 47 can be released, and under the action of the elastic element 50, the second clamping arm 47 can automatically move closer to the first clamping arm 46 to cooperate with the first clamping arm 46 to clamp the dispensing cartridge 45.

[0035] In some implementations, such as Figure 3 As shown, the first clamping arm 46 may also be provided with a receiving groove 461 for accommodating the elastic member 50, and the aforementioned through hole 462 is provided on the bottom surface of the receiving groove 461.

[0036] In order to secure the bolt shank 491 to the second clamping arm 47, in some embodiments, such as Figure 3 As shown, the bolt shank 491 is inserted into the connecting hole 472 on the second clamping arm 47. The second clamping arm 47 is also provided with a first threaded hole 471 extending through to the connecting hole 472. The aforementioned dispensing assembly 4 also includes a first screw 52, ​​which is used to thread into the first threaded hole 471 and to secure the bolt shank 491 against the connecting hole 472, so that the bolt shank 491 is fixedly connected to the second clamping arm 47.

[0037] In the above example, when the first screw 52 is tightened, the first screw 52 can secure the bolt shank 491 against the connecting hole 472, thereby fixing the bolt shank 491 onto the second clamping arm 47. When the first screw 52 is loosened, the bolt shank 491 can be pulled out from the connecting hole 472.

[0038] In some implementations, such as Figure 2-3 As shown, the aforementioned second clamping arm 47 may be provided with a handle 48 to facilitate the operation of the second clamping arm 47 by the operator.

[0039] In some implementations, such as Figure 1-3 As shown, the aforementioned third movable block 44 is provided with a positioning hole 473 through which the dispensing head of the dispensing cylinder 45 passes. The third movable block 44 is also provided with a sliding groove 441, and the first clamping arm 46 is provided with a slider 463 that slides in cooperation with the sliding groove 441. The bottom of the sliding groove 441 is provided with a second threaded hole 442. The slider 463 is provided with a through oblong hole 464. The dispensing assembly 4 also includes a second screw, which is used to pass through the oblong hole 464 and be threadedly connected to the second threaded hole 442.

[0040] In the above example, the first clamping arm 46 can be fixed to the third movable block 44 by the second screw. When the second screw is unscrewed from the second threaded hole 442, the position of the first clamping arm 46 can be adjusted within the range of the oblong hole 464, so that the dispensing head can be accurately inserted into the positioning hole.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
