Description

Technical Field

[0001] The utility model relates to the technical field of rivet assembly, in particular to a multi-point rivet assembly device. Background Art

[0002] Rivet assembly devices are important devices for assembling electronic devices such as laptop computers. Currently, the devices on the market are basically as follows:

[0003] 1. Multi-station assembly. At each station, multiple mechanisms of different specifications are used to take out a rivet from the feeder and assemble it to a specified position. When the assembly at this station is completed, the TOP part is moved to another station by the remaining mechanisms to assemble the remaining rivets. This mode has high efficiency. However, due to the small area of the TOP itself, too many rivet assembly mechanisms cannot be accommodated at each station at the same time. Therefore, more stations must be used, which will increase the floor area. At the same time, each rivet must be equipped with a uniquely designated rivet feeder, that is, one-to-one, which greatly increases the cost. Moreover, when switching stations, if the multi-path translation mode is used to switch the product station, there is a great possibility that the already assembled rivets will be damaged due to vibration during the movement, resulting in defects; while if the single-path translation mode is used to switch the product station, due to structural limitations, the floor area and manufacturing cost will be greatly increased again. When it comes to replacing different product types, each rivet feeder must be replaced, and at the same time, the assembly positions of each rivet assembly mechanism must also change. Due to the large number of stations, the number of toolings is also large, which greatly increases the cost of switching product types and the debugging time.

[0004] 2. Also multi-station assembly. At each station, one assembly mechanism is used to take out multiple rivets and then sequentially install them one by one into the specified positions. If there are some rivets of the same specification among the multiple rivets required on the TOP part, the assembly mechanism takes out rivets from the rivet feeder of the same specification multiple times and performs the assembly multiple times until the assembly is completed. This mode realizes one rivet for one type, rather than one-to-one in the first mode. Compared with the first mode, it reduces the cost and area. At the same time, since there is only one rivet assembly mechanism at each station, more rivets can be assembled at each station. Therefore, the number of stations can be reduced, and when replacing different product types, the cost and time will also be greatly reduced. However, the disadvantage is that the efficiency is too low and the production capacity cannot meet the actual production requirements. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi-point rivet assembly device, aiming to solve the problem of low production efficiency of the existing rivet assembly devices.

[0006] To achieve the above object, the utility model provides a multi-point rivet assembly device, which includes a workbench, a removal mechanism, two station switching mechanisms and a plurality of assembly mechanisms. The removal mechanism is installed on the workbench, the two station switching mechanisms are respectively installed on one side of the workbench close to the removal mechanism, and the plurality of assembly mechanisms are respectively installed on one side of the workbench close to the two station switching mechanisms.

[0007] Among them, the removal mechanism includes a transverse moving member and a grasping member. The transverse moving member is fixedly installed on the workbench, and the grasping member is installed on the output end of the transverse moving member.

[0008] Among them, the station switching mechanism includes a floating component and a plurality of tooling plates. The floating component is installed on one side of the workbench close to the transverse moving member, and the plurality of tooling plates are all installed on the floating component.

[0009] Among them, the station switching mechanism further includes a plurality of positioning plates, and the plurality of positioning plates are respectively fixedly connected to the workbench and are respectively located on one side of the workbench close to the tooling plate.
