Description

Technical Field

[0001] This utility model relates to the field of chip dispensing technology, and in particular to a fixed-point dispensing device for chip manufacturing. Background Technology

[0002] Chip dispensing is a common process technology used in semiconductor packaging and electronic manufacturing. By precisely controlling the application position and amount of adhesive, adhesive is applied to specific areas of chips, substrates, or electronic components for fixing, sealing, insulation, or thermal conduction to improve product reliability and performance. Common applications include chip packaging, LED packaging, and PCB protection. Its core equipment includes dispensing machines, needles, and control systems, requiring high precision, high stability, and a high degree of automation to meet the needs of micron-level processing.

[0003] Chinese patent CN217911262U discloses a precision dispensing device for chip manufacturing. This patent includes a worktable and a dispensing device located on the surface of the worktable. It also includes a moving assembly for moving the dispensing device. The moving assembly includes a U-shaped base plate, a motor, a lead screw, a screw block, and an L-shaped fixing plate. The motor is fixedly mounted on one side of the U-shaped base plate. By controlling the forward and reverse rotation of the motor, the lead screw rotates on the surface of the U-shaped base plate, causing the L-shaped fixing plate fixedly mounted on one side of the screw block to move the dispensing device until it reaches the designated position for precise positioning. A guide block fixedly mounted on the U-shaped base plate on the surface of the screw sleeve allows the moving assembly to move downwards, positioning the dispensing nozzle at the chip's dispensing location for precise positioning. The dispensing head has a built-in dispensing pump, which starts dispensing when aligned with the dispensing position.

[0004] In existing technologies, during the dispensing process, the dispensing gun is controlled to move along the XOY plane and perform dispensing at a specific location. However, the dispensing machine experiences displacement inertia errors as it moves along the guide rail, and given the high precision requirements of chip manufacturing, this can lead to inconsistent dispensing quality, necessitating improvements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pinpoint dispensing device for chip manufacturing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A chip manufacturing dot-dispensing apparatus includes a chassis and further includes:

[0008] The positioning component includes a rotor installed in the middle of the chassis, a universal disc at the output end of the rotor, a first slot at the extension arm of the universal disc, a sliding groove on one side of the chassis, a slider sliding inside the sliding groove, a positioning pin on the surface of the slider, and an electric telescopic rod on one side of the slider, which is fixed to one side of the sliding groove.

[0009] A further technical solution is that the universal disk has an "X"-shaped multi-flange structure, and the positioning pin has a cylindrical structure.

[0010] A further technical solution involves a tray fixedly mounted on the surface of the omnidirectional disk, with a second slot in the middle of the tray, and a chip installed inside the second slot.

[0011] Further technical solutions also include:

[0012] The dispensing assembly includes a vertical pole fixed to one side of the chassis, a suspension at the top of the vertical pole, and a telescopic cylinder on one side of the suspension.

[0013] A further technical solution involves installing an automatic glue dispensing gun at the output end of the telescopic cylinder.

[0014] A further technical solution involves installing a PLC controller on one side of the suspension. In this device, the rotor, electric telescopic rod, telescopic cylinder, and automatic glue dispensing gun are connected to one side of the PLC controller.

[0015] A further technical solution involves positioning the dispensing area of ​​the automatic dispensing gun directly above the chip dispensing area.

[0016] Compared with the prior art, the present invention provides a pinpoint dispensing device for chip manufacturing, which has the following advantages:

[0017] This invention utilizes a fixed-point positioning component, which includes a positioning locking mechanism around the rotating chip's omnidirectional disk. When the chip rotates to a specific dispensing area, a positioning pin in the locking mechanism engages with a slot to achieve a fixed-point stop. The dispensing machine itself only needs to move vertically and descend to a specific height to complete the dispensing. This fixed-point stopping method avoids errors caused by inertia during long-distance movement of the dispensing machine. Attached Figure Description

[0024] Example 1: Refer to Figure 1 - Figure 4 A chip manufacturing dot-dispensing apparatus includes a chassis 1, and further includes:

[0025] The positioning component 2 includes a rotor 4 installed in the middle of the chassis 1. The rotor 4 indirectly controls the rotation of the chip 9 inside the slot 8 via a universal disk 5. The output end of the rotor 4 is provided with the universal disk 5, and the extended arm of the universal disk 5 is provided with a slot 6; the slot 6 is the embedding structure for subsequent positioning components. A slide groove 10 is provided on one side of the chassis 1. An electric telescopic rod 13 controls the slider 11 to slide inside the slide groove 10. The positioning pin 12 on the top of the slider 11 is embedded inside the slot 6 during movement to achieve positioning. The slider 11 is slidably arranged inside the slide groove 10. The surface of the slider 11 is provided with a positioning pin 12. An electric telescopic rod 13 is provided on one side of the slider 11 and is fixed to one side of the slide groove 10.

[0026] The chip manufacturing fixed-point dispensing device has an "X"-shaped multi-flange structure for the universal disk 5 and a cylindrical structure for the positioning pin 12.

[0027] The aforementioned chip manufacturing dispensing device includes a tray 7 fixedly mounted on the surface of the universal disk 5. A slot 8 inside the tray 7 serves as the receiving point for the chip 9. The slot 8 is located in the middle of the tray 7, and the chip 9 is installed inside the slot 8.

[0028] The chip manufacturing dot-dispensing apparatus further includes:

[0029] The dispensing assembly 3 includes a vertical rod 14 fixed to one side of the chassis 1, and a suspension 15 is provided on the top of the vertical rod 14. The vertical rod 14 and the suspension 15 are the suspension components of the telescopic cylinder 17. The telescopic cylinder 17 is provided on one side of the suspension 15.

[0030] The chip manufacturing fixed-point dispensing device is provided with an automatic dispensing gun 18 at the output end of the telescopic cylinder 17, which is used to achieve automatic dispensing effect at the dispensing point.

[0031] In the chip manufacturing fixed-point dispensing device, a PLC central controller 16 is installed on one side of the suspension 15. The PLC central controller 16 is used to centrally control all electrical components of this device. In this device, the rotor 4, electric telescopic rod 13, telescopic cylinder 17, and automatic dispensing gun 18 are connected to one side of the PLC central controller 16.

[0032] The chip manufacturing fixed-point dispensing device has an automatic dispensing gun 18 with its dispensing part positioned directly above the dispensing part of the chip 9, sinking down to a specific position to achieve the dispensing effect.

[0033] Working Principle: In the actual design process, this utility model addresses the following shortcomings in existing technologies: "In existing technologies, during the dispensing process, the dispensing gun is controlled to move on the XOY plane and then dispensing is performed at a specific dispensing location. However, there is a certain displacement inertia error during the movement of the dispensing machine on the guide rail, and chip manufacturing requires high precision, which will lead to unstable dispensing quality. Therefore, improvements are needed." Therefore, a fixed-point positioning component 2 and a dispensing component 3 are specifically proposed.

[0034] Positioning component 2:

[0035] The component consists of two parts: a rotating part and a locking part. The rotating part involves a rotor 4 driving a top-mounted omnidirectional disc 5 to rotate, mounting the chip 9 inside the slot 8 of the tray 7. The locking part includes a groove 10 on one side of the chassis 1, allowing a slider 11 to slide within it. The control component is an electric telescopic rod 13 mounted on one side of the groove 10. The electric telescopic rod 13 controls a positioning pin 12 on one side of the slider 11 within the groove 10, which in turn abuts against the slot 6, stopping the chip 9 inside the turntable. This stopping point is precisely where adhesive needs to be applied.

[0036] Dispensing component 3:

[0037] This component mounts the dispensing device directly above the chip dispensing area via a pole 14 and a suspension 15. An automatic dispensing gun 18 extends to the chip dispensing area via a telescopic cylinder 17, thus achieving the dispensing effect. Furthermore, to achieve global automatic control, a PLC controller 16 is installed on one side of the suspension 15, enabling overall synchronous control.
