[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a chip encapsulation device with a protection mechanism includes an encapsulation machine body 1. A column 2 is fixedly connected to the upper surface of the encapsulation machine body 1. An upper end of the column 2 is fixedly connected to a mounting seat 3. A slide seat 4 is slidably connected to an outer surface of the mounting seat 3. A moving seat 403 is movably embedded in a front surface of the slide seat 4. A fixed seat 406 is movably embedded in a lower surface of the moving seat 403. A glue pen body 5 is fixedly connected to a front surface of the fixed seat 406. A limit sleeve 6 is nested on an outer surface of the glue pen body 5. Two swing frames 602 are rotatably connected to a rear surface of the limit sleeve 6. An end of the swing frame 602 is movably embedded with a square rod 607. A protective sleeve 608 is nested on an outer surface of the square rod 607.

[0023] Specifically, when in use, the position of the glue pen body 5 is adjusted through the slide seat 4, and the chip is injected with glue for encapsulation through the glue pen body 5. When the glue pen body 5 is not in use, the glue head 501 is sealed by two protective sleeves 608 to prevent external objects from directly contacting the glue head 501 during idling, resulting in damage to the glue head 501 due to impact.

[0024] Embodiment 1

[0025] As Figures 1-4As shown in the figure, a clamp 101 is movably disposed on the upper surface of the encapsulation machine body 1. A motor 301 is fixedly connected to the outer surface of the mounting base 3. The output end of the motor 301 is fixedly connected to a lead screw 302. The lead screw 302 is in threaded connection with a sliding seat 4. A first hydraulic rod 401 is fixedly connected to the rear surface of the sliding seat 4. The output end of the first hydraulic rod 401 is fixedly connected to a moving seat 403. A first limiting rod 402 is fixedly connected to the rear surface of the moving seat 403. The first limiting rod 402 penetrates through the sliding seat 4.

[0026] In this embodiment, the clamp 101 is used to clamp the chip. When the motor 301 is started, the output end of the motor 301 drives the lead screw 302 to rotate. Under the push of the thread, the sliding seat 4 can move horizontally. When the first hydraulic rod 401 is started, the output end of the first hydraulic rod 401 cooperates with the first limiting rod 402 to drive the moving seat 403 to move in the front-back direction.

[0027] As Figures 1-4 shown, a second hydraulic rod 404 is fixedly connected to the upper surface of the moving seat 403. The output end of the second hydraulic rod 404 is fixedly connected to a fixed seat 406. A second limiting rod 405 is fixedly connected to the upper surface of the fixed seat 406. The second limiting rod 405 penetrates through the moving seat 403.

[0028] In this embodiment, the output end of the second hydraulic rod 404 cooperates with the second limiting rod 405 to drive the fixed seat 406 to move in the up-down direction.

[0029] Embodiment Two

[0030] On the basis of Embodiment One, in order to make up for the problem that it is inconvenient to protect the dispensing head 501 in Embodiment One.

[0031] As Figures 1-4 shown, a dispensing head 501 is fixedly connected to the lower surface of the dispensing pen body 5. Limiting knobs 601 are threadedly connected to both side surfaces of the limiting sleeve 6.

[0032] In this embodiment, when the limiting knob 601 is rotated, under the push of the thread, one end of the limiting knob 601 is separated from the dispensing pen body 5. At this time, the position of the limiting sleeve 6 can be adjusted.

[0033] As Figures 1-4 shown, a gear 603 is fixedly connected to the rear surface of the swing frame 602. A rack 604 is fixedly connected to the front surface of the moving seat 403. The gear 603 is in meshing connection with the rack 604. A limiting seat 605 is fixedly connected to the outer surface of the limiting sleeve 6. The limiting seat 605 is in sliding connection with the rack 604. A first fastening knob 606 is threadedly connected to the end of the swing frame 602. A second fastening knob 609 is threadedly connected to the outer surface of the protective sleeve 608.

[0034] In this embodiment, when the limit seat 605 descends for glue injection encapsulation, the rack 604 meshes with the gear 603, causing the gear 603 to drive the swing frame 602 to turn outwards. Thus, the protective cover 608 that seals the dispensing head 501 can be turned outwards, removing the obstruction outside the dispensing head 501 and facilitating the glue injection encapsulation operation. When the limit seat 605 ascends, the swing frame 602 drives the protective cover 608 to seal the dispensing head 501, preventing external objects from directly contacting the dispensing head 501 when the device is idle, which could cause a direct impact on the dispensing head 501. Moreover, the sealing protection can reduce the interference of external factors on the dispensing head 501, improve the accuracy of glue injection, and ensure the quality and consistency of chip encapsulation. By reducing the failure rate and maintenance time of the dispensing head 501, the operating efficiency of the production line can be increased and the production cost can be reduced. When the protective cover 608 needs to be replaced, rotate the second fastening knob 609 to separate the second fastening knob 609 from the square rod 607, and the protective cover 608 will lose its external fixation, facilitating the replacement of the protective cover 608. Similarly, rotate the first fastening knob 606 to separate the first fastening knob 606 from the square rod 607, and the position of the square rod 607 can be manually adjusted to facilitate the adaptation to different protective covers 608.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms.
