[0029] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this application.

[0030] The first embodiment of this application provides a feeding and carrying mechanism for carrying a material box containing a lead frame. This mechanism is mounted on a lifting drive mechanism of a feeding device and moves vertically under the drive of the lifting drive mechanism during operation. Figures 1-5 As shown in the figure, the feeding and carrying mechanism of this embodiment includes a mounting component 1 and a carrying component 2. In this embodiment, the mounting component 1 is a vertical mounting plate, which is used for mounting the carrying component 2 and is mounted together with the carrying component on the lifting drive mechanism. Therefore, structurally, the mounting component 1 is connected to the lifting drive mechanism. The carrying component 2 is in a horizontal state when in operation and is used to place the material box. The carrying component 2 has a horizontal carrying surface. The carrying component 2 and the mounting component 1 can be connected by a limiting structure to ensure that the carrying component 2 is in a horizontal state in its natural state, thus forming the horizontal carrying surface.

[0031] When the support member 2 is a single integral component, the horizontal support surface can be a horizontal surface provided on the support member 2. When the support member 2 is composed of multiple components, the horizontal support surface can be a horizontal surface formed by multiple components.

[0032] Preferably, in this embodiment, the carrier 2 adopts a structure composed of multiple components. Specifically, the carrier 2 includes at least two claws 21, and the at least two claws 21 constitute the bearing surface of the carrier 2 when they are located on the same horizontal plane.

[0033] To avoid generating sufficient downward pressure to cause harm to people or objects below during the descent of the support member 2, as well as a reaction force that could damage the support member 2, in this embodiment, the support member 2 and the mounting member 1 are connected by a pivot joint structure. After connecting the mounting member 1 and the support member 2 through the pivot joint structure, when the support member 2 is obstructed from below, it can naturally fold upward along the pivot joint structure. As the degree of downward pressure increases, the folding angle also increases accordingly, thereby avoiding rigid contact between the support member 2 and people or objects below, and converting it into a flexible contact, thus effectively avoiding damage caused by excessive interaction forces.

[0034] In terms of the specific structural configuration of the rotating shaft mating structure, generally speaking, the rotating shaft mating structure includes a first mating part 3 provided on the mounting member, a second mating part 4 provided on the bearing member, and a rotating shaft 5 connecting the first mating part and the second mating part.

[0035] Because of the above structure, the carrier can be folded relative to the mounting component along the axis of rotation. When the carrier moves vertically downwards and comes into contact with the worker's limbs or other materials, the carrier lifts up, which not only protects the worker's operating safety but also avoids forcibly pressing down on the materials and prevents the carrier itself from deforming due to stress. The structure is simple and effective.

[0036] In this embodiment, the first mating part 3 is an outer shaft seat provided on the mounting component. The number of the outer shaft seats corresponds to the number of the claws. Each outer shaft seat includes a first seat body 31 and a second seat body 32 arranged opposite to each other. The first seat body 31 and the second seat body 32 are provided with an outer shaft hole 33. There is a gap between the first seat body 31 and the second seat body 32.

[0037] Preferably, in this embodiment, the first mating part 3 and the mounting part 1 are integrally formed. Processing the first mating part 3 and the mounting part 1 as an integrally formed structure can effectively control processing accuracy and reduce subsequent assembly.

[0038] Corresponding to the structure of the first mating part 3 described above, in this embodiment, the second mating part 4 is an inner shaft seat provided on the claw 21. The inner shaft seat is provided with an inner shaft hole 22. When the inner shaft seat is installed, it is located in the gap between the first seat body 31 and the second seat body 32 and is movably connected through the rotating shaft 5.

[0039] To ensure that the claw 21 remains horizontal naturally without external force, one end of the claw 21 is provided with an abutment portion 23. The abutment portion 23 cooperates with the mounting member 1 to limit the rotation angle of the claw. When the claw 21 is in its natural state, the abutment portion 23 abuts against the lower surface of the mounting member 1, thereby achieving effective limiting.

[0040] Due to limitations in machining precision and gaps in the installation and fitting structures, a slight error may exist when the aforementioned abutment portion 23 is used to cooperate with the mounting component 1 to maintain the horizontality of the claw 21. This can cause differences in the angles between the multiple claws 21, resulting in an uneven horizontal surface formed by the multiple claws 21. To address this issue, in this embodiment, the mounting component 1 has a vertical through hole 11 corresponding to the abutment portion, and an adjusting nut 12 is provided in the vertical through hole. After the claw 21 is installed, the adjusting nut 12 can be adjusted to control the length of the adjusting nut extending from the bottom surface of the mounting component, thereby acting on the abutment portion 23 and adjusting the angle of the claw 21 accordingly.

[0041] like Figure 6 As shown, the second embodiment of this application also provides a feeding device, including the feeding and carrying mechanism described in the first embodiment. In this embodiment, the feeding device includes a frame 6, on which a lifting drive mechanism 7 is provided. The feeding and carrying mechanism described in the first embodiment is mounted on the lifting drive mechanism 7. The lifting drive mechanism 7 drives the feeding and carrying mechanism to lift and lower the material rack a, and during the lifting and lowering process, the lead wire bracket in the material rack a is conveyed step by step to the lead wire bonding mechanism. Figure 2 As can be seen from the above, when there is an object b on the base 8 of the feeding device, when the feeding bearing mechanism comes into contact with the object b during its descent, the claw in the feeding bearing mechanism can be folded upward to avoid hard contact between the two.

[0042] In this embodiment, the feeding device can be a standalone device located next to the bonding equipment, or it can be installed on the bonding equipment as part of the bonding equipment.

[0043] The third embodiment of this application also provides a bonding device, including a feeding device, which includes the feeding carrier mechanism described in the first embodiment above.

[0044] The above description is merely a preferred embodiment of the present application and does not limit the scope of disclosure of the embodiments of the present application. Any equivalent structural or procedural transformations made using the description and drawings of the embodiments of the present application, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection supported by the embodiments of the present application.
