Detailed Implementation

[0022] Example 1, please refer to Figures 1 to 3 This is a schematic diagram of a screen cable pressure-holding bonding and welding mechanism provided by this utility model. The screen cable pressure-holding bonding and welding mechanism includes: an assembly platform 10, screen positioning fixtures 40 and cable positioning fixtures 20 spaced apart on the assembly platform 10, and a pressure-holding bonding and welding assembly 80 disposed on one side of the assembly platform 10. It is conceivable that this screen cable pressure-holding bonding and welding mechanism also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0023] The assembly machine 10 is a flat surface or equipment platform. In this embodiment, the assembly machine 10 is a rotating platform with self-drive function.

[0024] In this embodiment, the screen positioning fixture 40 includes a screen positioning block 41 disposed on the assembly machine 10 for positioning and placing the screen. The screen positioning block 41 is provided with a lateral positioning edge 42 and a sliding positioning block 43 disposed on a sliding side away from the lateral positioning edge 42. The sliding positioning block 43 is directly driven by a cylinder or a cylinder-driven pusher is used to move the sliding positioning block 43. The screen positioning fixture 40 uses the lateral positioning edge 42 as a single-sided reference edge, and the sliding positioning block 43 forms a clamp when it approaches.

[0025] Alternatively, a sliding positioning elastic element, such as a spring, can be used to elastically connect the sliding positioning block 43 and the assembly platform, forcing the sliding positioning block 43 to have a driving tendency to move towards the side of the sliding positioning block 43, so as to achieve the purpose of elastic clamping of the screen.

[0026] In this embodiment, the cable positioning fixture 20 includes a cable positioning block 21 vertically slidably mounted on the assembly platform 10. An installation notch is provided at the upper edge of the assembly platform 10. The cable positioning block 21 is positioned within the installation notch to improve the compactness of the installation structure and to provide vertical sliding installation space for the cable positioning block 21 at the edge of the assembly platform 10. The cable positioning block 21 is slidably connected to the assembly platform 10 via a vertical slide rail. An installation limiting plate 11 is provided at the bottom of the assembly platform 10. A cable assembly elastic member 31, which is a spring structure, is provided between the installation limiting plate 11 and the cable positioning block 21, forcing the cable positioning block 21 to have an upward sliding tendency. A lifting telescopic shaft 33 passes through the installation limiting plate 11 and acts on the cable assembly elastic member 31. A bearing on the installation limiting plate 11 allows the lifting telescopic shaft 33 to pass axially. A cable positioning groove 22 is recessed in the cable positioning block 21. The cable positioning groove 22 is used for the initial positioning of the cable when it is transferred to the cable positioning block 21. The cable assembly elastic element 31 makes elastic contact when the cable is transferred to the cable positioning groove 22, avoiding bending and damage to the cable structure due to downward pressure. The size of the cable positioning groove 22 is larger than the size of the cable, reducing the difficulty of cable transfer.

[0027] In this embodiment, a cable positioning block 21 is provided with a cable limiting block 23 that can press against the upper end of the cable positioning groove 22. The cable positioning block 21 is provided with a limiting guide groove 27 that communicates with the cable positioning groove 22. The cable limiting block 23 is guided through the limiting guide groove 27, abuts against the side wall of the cable, and is clamped between the cable limiting block 23 and the cable positioning groove 22, while simultaneously pressing against the upper end of the cable, achieving stable and precise positioning. In addition, the cable positioning block 21 is also provided with a sliding strip hole 28, and the cable limiting block 23 is provided with a sliding guide block 29 that is slidably disposed in the sliding strip hole 28. The sliding cooperation between the sliding guide block 29 and the sliding strip hole 28 increases the sliding accuracy between the cable limiting block 23 and the cable positioning block 21, increasing clamping stability.

[0028] like Figure 3 , Figure 5 As shown, optimizedly, a spring-loaded elastic element 25 is provided between the cable positioning block 21 and the cable limiting block 23, allowing the cable limiting block 23 to elastically connect with the cable, thus avoiding damage to the cable caused by rigid contact. It should be further noted that in other workstations, such as the cable loading and unloading stations, the cable limiting block 23 is connected to a cable positioning driver 24 for driving the cable limiting block 23. The cable positioning driver 24 is a cylinder structure used to resist the elastic resistance of the spring-loaded elastic element 25, enabling the cable limiting block 23 to move away from the cable positioning groove 22 to complete the unlocking operation.

[0029] Ideally, the cable limiting block 23 is provided with a limiting step 26 that can abut against the cable positioning block 21. The limiting step 26 is used to limit the maximum lateral travel of the cable limiting block 23 and plays a clamping and protective role.

[0030] In this embodiment, when both the screen and the ribbon cable are in the positioning state, the welding position of the two is set on the ribbon cable positioning block 21, the ribbon cable welding point is located at the upper end, and the welding point of the screen protrudes from the screen positioning fixture 40 and presses against the upper end of the ribbon cable welding point.

[0031] In this embodiment, as Figure 3 and 4 As shown, the pressure-holding bonding welding assembly 80 includes a welding frame 81 disposed on one side of the assembly machine 10. The welding frame 81 serves as an installation carrier. A welding positioning frame 82, one end of which can press down on the ribbon cable positioning block 21, is slidably disposed on the welding frame 81. The welding positioning frame 82 is slidably connected to the welding mechanism via a slide rail and moves vertically. It is also connected to a welding positioning driver 84, which is a cylinder used to drive the welding positioning frame 82 to slide vertically. The welding positioning frame 82 acts at the welding point between the screen and the ribbon cable. A pressure-holding abutment block 35 is provided below the ribbon cable assembly elastic element 31 and is located at the output end of the cylinder. The pressure-holding abutment block 35 acts on the lifting telescopic shaft 33, compressing the ribbon cable assembly elastic element 31 while lifting the ribbon cable positioning block 21. This, combined with the downward pressure of the welding positioning frame 82 above, ensures a stable and pressure-holding bonding between the screen welding position and the ribbon cable welding position, preventing incomplete welding during the welding process. After welding is completed, the cylinder returns to its original position.

[0032] A welding positioning hole 83 is provided through the end of the welding positioning frame 82. The welding positioning hole 83 serves as a reserved space for welding. A laser welding head 85 is provided above the welding positioning hole 83. The energy emitted by the laser welding head 85 passes through the welding positioning hole 83 and acts on the bonding welding position between the screen and the ribbon cable, completing the laser welding in the exposed area.

[0033] In this embodiment, the bottom of the welding positioning frame 82 is provided with a protruding annular positioning frame 86, which reduces the contact area between the welding positioning frame 82 and the upper end of the cable, increases the height between the two, and improves the positioning accuracy of the positioning pressure.

[0034] Ideally, the welding positioning frame 82 is provided with an inclined bending section 87 at one end near the welding positioning hole 83. The inclined bending section 87 can further increase the distance between the welding positioning frame 82 and the upper end of the cable, thus avoiding interference with other components.

[0035] A welding protection frame 88 is provided on the outer circumference of the welding positioning frame 82, which expands the welding spatter protection range of the welding positioning frame 82 at the welding position. A welding protection plate 89 is provided on the assembly machine 10 above the screen positioning fixture 40, which is used to protect the welding above the screen.

[0036] It should be noted that the cylinder, motor, and laser welding head 85 involved in this utility model are all commercially available parts and are existing technologies. Their specific models will not be described here.

[0037] Example 2: This utility model also provides a shaping and welding production line, which has the screen cable pressure holding and bonding welding mechanism as described above. Except for the screen cable pressure holding and bonding welding mechanism, the other components are all existing technology or commercially available parts, and will not be described in detail here.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
