Description

Technical Field

[0001] The invention relates to the technical field of electronic product assembly, and in particular to an assembly tool for electronic products. Background Art

[0002] Electronic products, such as mobile phones, cameras, watches, and tablets, have a variety of accessories installed on their motherboards, such as camera accessories, player accessories, and charging accessories. The circuit boards of various accessories are plugged into the sockets on the motherboard through row plugs. Due to the small size of various accessories, they may need to be sucked up with a vacuum nozzle before being plugged into the motherboard. After the row plugs of various accessories are aligned with the sockets on the motherboard, the accessories are pressed to insert the row plugs into the sockets on the motherboard. When pressing the accessories, a pressing tool is required. In this way, the assembly of accessories and motherboards requires the use of suction tools and pressing tools, which is not conducive to improving work efficiency. Summary of the invention

[0003] The technical problem solved by the present invention is that the assembly of accessories and electronic product motherboards requires the use of adsorption tools and pressing tools, which is not conducive to improving work efficiency.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a magnetic suction pen, comprising an outer cylinder, and a movable component and a fixed component matched in the outer cylinder, the fixed component is fixedly connected to the outer cylinder by a transversely arranged fixing pin, the lower end of the fixed component protrudes downward from the outer cylinder, and the lower end of the fixed component is provided with a magnet; the movable component is movably sleeved outside the fixed component, the movable component is provided with a strip guide groove, the strip guide groove is movably matched with the fixing pin, the upper end of the movable component protrudes upward from the outer cylinder, a reset spring is provided between the upper end of the movable component and the outer cylinder, the lower end of the movable component can protrude downward from the outer cylinder, and the length of the fixed component protruding downward from the movable component is less than the length of the strip guide groove.

[0005] According to the above technical solution, the operator holds the outer cylinder of the magnetic suction pen and uses the magnet to absorb the accessory, so that the upper surface of the accessory fits with the lower end surface of the fixed component. The operator uses the magnetic suction pen to move the accessory to the installation position of the mainboard, and aligns the row plug of the accessory with the socket on the mainboard. After that, the operator presses the upper end of the movable component to make the movable component descend relative to the outer cylinder and the fixed component, and the lower end of the movable component protrudes downward from the outer cylinder, and the lower end surface of the movable component is moved to be flush with the lower end surface of the fixed component. In this way, the lower end surface of the movable component presses on the accessory and presses the accessory down on the mainboard. The lower end surface of the movable component continues to descend and is lower than the lower end surface of the fixed component. The movable component presses the row plug of the accessory with the socket on the mainboard, and at the same time, the lower end surface of the fixed component is separated from the accessory. After that, the operator lifts up the magnetic suction pen to complete the installation of the accessory on the mainboard.

[0006] The present invention uses magnets to absorb accessories. Since some parts cannot be absorbed by magnets, the magnetic suction pen of the present invention can only obtain and install accessories that can be absorbed by magnets. Since the acquisition and installation of accessories are completed continuously by the same magnetic suction pen, the operation is convenient and the work efficiency is high.

[0007] The fixing assembly includes a magnet fixing part and a fixing pin connecting part. The magnet fixing part is provided with a plug hole and a magnet mounting hole matched with the magnet. The fixing pin connecting part is provided with a plug connector matched with the plug hole and a fixing pin hole matched with the fixing pin. The fixing pin connecting part and the magnet fixing part are fixedly connected by plugging the plug connector with the plug hole. The lower end surface of the magnet fixing part is provided with a magnet mounting hole for accommodating the magnet.

[0008] The movable component includes a sleeve member, a rod member and a pressing member. The upper end of the sleeve member is fixedly connected to the lower end of the rod member through a connecting pin. The pressing member is inserted into the upper end of the rod member. The strip guide groove is arranged on the side wall of the sleeve member. The sleeve member is movably sleeved outside the fixed component. A first limiting step is formed between the pressing member and the rod member. A second limiting step is arranged on the inner side wall of the outer cylinder member. The upper end of the reset spring abuts against the first limiting step, and the lower end of the reset spring abuts against the second limiting step.

[0009] The operator presses the pressing piece, and the entire movable assembly descends relative to the outer cylinder and the fixed assembly, and the reset spring is compressed. Since the length of the fixed assembly protruding downward from the movable assembly is less than the length of the strip guide groove, when the movable assembly descends to the limit position, that is, when the fixed pin abuts against the inner top of the strip guide groove, the lower end face of the movable assembly, that is, the lower end face of the sleeve, is lower than the lower end face of the fixed assembly. In this way, the sleeve can press the accessory and separate the accessory from the lower end face of the fixed assembly. The operator releases the pressing piece, the reset spring releases the elastic potential energy, the movable assembly rises and resets, and the fixed pin abuts against the inner bottom of the strip guide groove.

[0010] A fixing pin positioning hole is arranged on the side wall of the outer cylinder, and the fixing pin is inserted into the fixing pin positioning hole and simultaneously inserted into the fixing pin hole of the fixing assembly to realize the fixed connection between the fixing assembly and the outer cylinder.

The lower end of the fixed component is provided with a magnet 31. The movable component is movably sleeved outside the fixed component. The movable component is provided with a strip guide groove 210. The strip guide groove is movably matched with the fixed pin. The upper end of the movable component protrudes upward from the outer cylinder 10. A reset spring 50 is provided between the upper end of the movable component and the outer cylinder. The lower end of the movable component can protrude downward from the outer cylinder. The length of the fixed component protruding downward from the movable component is less than the length of the strip guide groove.

[0028] The operator holds the outer cylinder 10 of the magnetic suction pen and uses the magnet 31 to absorb the accessory, and the upper surface of the accessory fits with the lower end surface of the fixed component 30. The operator uses the magnetic suction pen to move the accessory to the installation position of the mainboard and aligns the row plug of the accessory with the socket on the mainboard. After that, the operator presses the upper end of the movable component 20 to make the movable component 20 descend relative to the outer cylinder 10 and the fixed component 30, and the lower end of the movable component 20 protrudes downward from the outer cylinder 10, and the lower end surface of the movable component 20 is displaced to be flush with the lower end surface of the fixed component 30. In this way, the lower end surface of the movable component 20 presses on the accessory and presses the accessory down on the mainboard. The lower end surface of the movable component 20 continues to descend and is lower than the lower end surface of the fixed component 30. The movable component 20 presses the row plug of the accessory with the socket on the mainboard, and at the same time, the lower end surface of the fixed component 30 is separated from the accessory. After that, the operator lifts the magnetic suction pen to complete the installation of the accessory on the mainboard.
