Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, specifically to a screen packaging device for display screen processing. Background Technology

[0002] In LED display manufacturing, desktop automatic dispensing machines are core equipment in the packaging process, covering the entire workflow from chip-level phosphor coating and chip fixation to module-level sealing and reinforcement. Whether it's the reliable connection between the chip and substrate in traditional SMD packaging or the extreme demands of micro-adhesive control in emerging Mini / Micro LEDs, its high precision and high consistency technical characteristics perfectly match the stringent requirements of LED packaging. Through precise adhesive volume control, stable motion trajectory, and multi-adhesive material compatibility, it effectively ensures packaging quality and efficiency, remaining an indispensable core device for LED display packaging, from phosphor uniformity to sealing reliability.

[0003] Currently, desktop automatic dispensing machines commonly use the traditional method of bolts and pressure blocks for mold fixing. This requires tightening each bolt and adjusting the position of the pressure block one by one, a cumbersome and time-consuming process. This fixing method not only increases preparation time but also easily leads to bolt stripping or pressure block loosening due to frequent disassembly and assembly, affecting mold positioning accuracy. For production scenarios such as LED display packaging that require frequent mold changes, the traditional bolt fixing mode has become a significant bottleneck restricting the improvement of production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screen packaging device for display screen processing, which makes the mold fixing process simpler and more convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen packaging device for display screen processing, comprising a dispensing machine body, a base plate slidably connected to the top of the dispensing machine body, a slide plate slidably connected inside the base plate, a bidirectional lead screw threadedly connected to the middle position of the slide plate, the bidirectional lead screw being rotatably connected to the base plate, a gear rotatably connected to the middle position of the top of the slide plate, a left rack plate and a right rack plate respectively meshing on both sides of the gear, and an extrusion block fixedly connected to the end of the left rack plate and the right rack plate away from the gear.

[0006] Furthermore, both ends of the bottom of the skateboard are slidably connected to slide rails, and the slide rails are fixedly connected to the base plate.

[0007] Furthermore, a turntable is provided at the end of the bidirectional lead screw, and the turntable is fixedly connected to the bidirectional lead screw.

[0008] Furthermore, a sliding groove is provided at the middle position of the bottom of both the left and right rack plates. A slider is slidably connected inside the sliding groove. A spring is fixed to the side of the slider away from the extrusion block, and the other end of the spring is fixed to the end of the sliding groove.

[0009] Furthermore, a sliding rod is slidably connected to the middle position of the slider, the spring is sleeved on the outside of the sliding rod, and the two ends of the sliding rod are respectively fixed to the two ends of the sliding groove.

[0010] Furthermore, a sleeve is fixedly connected to one end of the extrusion block away from the base plate, and a connecting rod is slidably connected to the middle position of the sleeve.

[0011] Furthermore, both ends of the connecting rod are fixedly connected to end plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This type of screen packaging equipment for display screen processing only requires placing the mold in the middle of the top of the base plate when it needs to be fixed. Then, the extrusion block is pulled to both sides to align the groove on the extrusion block with the corner of the mold. Next, the bidirectional screw is rotated to move the extrusion block toward the mold, thereby pressing and fixing the mold by the extrusion block. The whole fixing process is simple, convenient and easy to operate. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-5 A screen packaging device for display screen processing includes a dispensing machine body 1. A base plate 2 is slidably connected to the top of the dispensing machine body 1. A slide plate 4 is slidably connected inside the base plate 2. A bidirectional lead screw 5 is threadedly connected to the middle position of the slide plate 4. The bidirectional lead screw 5 is rotatably connected to the base plate 2. A gear 7 is rotatably connected to the middle position of the top of the slide plate 4. A left rack plate 8 and a right rack plate 9 are respectively meshed on both sides of the gear 7. An extrusion block 10 is fixedly connected to the end of the left rack plate 8 and the right rack plate 9 away from the gear 7.

[0017] The screen packaging equipment for display screen processing in this utility model only requires placing the mold in the middle of the top of the base plate 2 when it is necessary to fix the mold. Then, the extrusion block 10 is pulled to both sides so that the groove on the extrusion block 10 is aligned with the corner of the mold. Then, the bidirectional lead screw 5 is rotated so that the extrusion block 10 moves to the middle of the base plate 2 at the same time, that is, moves towards the mold. Thus, the mold is squeezed and fixed by the extrusion block 10. The whole fixing process is simple, convenient and easy to operate. In addition, since the dispensing machine body 1 is an existing mature product, it will not be described in detail here.

[0018] like Figure 2 and Figure 3 As shown, slide rails 3 are slidably connected to both ends of the bottom of the slide plate 4, and the slide rails 3 are fixedly connected to the base plate 2.

[0019] Specifically, the slide rail 3 restricts the skateboard 4, making the skateboard 4 slide more smoothly.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a turntable 6 is provided at the end of the bidirectional lead screw 5, and the turntable 6 is fixedly connected to the bidirectional lead screw 5.

[0021] Specifically, rotating the bidirectional lead screw 5 via the turntable 6 is more labor-saving and convenient.

[0022] like Figure 4 and Figure 5 As shown, a groove 14 is provided at the middle position of the bottom of the left rack plate 8 and the right rack plate 9. A slider 15 is slidably connected inside the groove 14. A spring 16 is fixedly connected to the side of the slider 15 away from the extrusion block 10. The other end of the spring 16 is fixedly connected to the end of the groove 14.

[0023] like Figure 4 and Figure 5 As shown, a slide rod 17 is slidably connected to the middle position of the slider 15, and a spring 16 is sleeved on the outside of the slide rod 17. The two ends of the slide rod 17 are respectively fixed to the two ends of the slide groove 14.

[0024] Specifically, when one of the extrusion blocks 10 is pulled, the extrusion block 10 will drive the left rack plate 8 or the right rack plate 9 to move. The left rack plate 8 or the right rack plate 9 will then drive the gear 7 that meshes with it to rotate. The gear 7 will then drive the right rack plate 9 or the left rack plate 8 to move, thereby causing the other extrusion block 10 to move synchronously. At the same time, when the extrusion block 10 is pulled away from the base plate 2, the spring 16 will be compressed. Therefore, after the extrusion block 10 is released, the spring 16 will push the extrusion block 10 towards the middle position of the base plate 2, so that the extrusion block 10 has a better extrusion and fixing effect on the mold.

[0025] like Figure 2 and Figure 4 As shown, a sleeve 11 is fixedly connected to one end of the extrusion block 10 away from the base plate 2, and a connecting rod 12 is slidably connected to the middle position of the sleeve 11.

[0026] like Figure 2 As shown, both ends of the connecting rod 12 are fixed with end plates 13.

[0027] Specifically, the two extrusion blocks 10 located on the same side of the base plate 2 are connected together by the connecting rod 12, making it easier for the extrusion blocks 10 to move. At the same time, the end plate 13 can prevent the connecting rod 12 from detaching from the sleeve 11.

[0028] It is worth noting that: the four extrusion blocks 10 have grooves near the center of the base plate 2 (such as... Figure 1 and Figure 2 As shown in the image, the groove is rectangular and suitable for fixing most molds with four corners.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
