Jig for assembling magnets in keyboard aluminum rod

Abstract

The invention relates to a jig for assembling magnets in a keyboard aluminum rod. The jig comprises a worktable, a magnet assembling jig and a parallel pneumatic claw. The magnet assembling jig comprises a base and a magnet positioning mechanism. The magnetic positioning mechanism comprises three steel bars, two elongated baffle plates and a positioning block. Two elongated intervals are formed among the three steel bars. The two elongated baffle plates are arranged in the two elongated intervals. Furthermore a linear elastomer is arranged between the bottom surface of each elongated baffle plate and the bottom surface of the corresponding elongated interval. The top surface of the middle steel rod and the two elongated baffle plates form an elongated recessed trough. A positioning block is arranged at one end of the elongated recessed trough. The positioning block is provided with a through hole which corresponds with and is communicated with the elongated recessed trough. The other end of the elongated recessed trough is provided with a block. The left sliding claw and the right sliding claw of the parallel pneumatic claw penetrate out the base and are arranged at two ends of the elongated recessed trough. The upper end of the left sliding claw and the upper end of the right sliding claw are provided with projections. The jig for assembling the magnets in the keyboard aluminum rod has advantages of high assembling efficiency for bulk magnets, low rejection rate, low appearance defective rate and low integral offset defective rate.

Description

technical field [0001] The invention relates to a jig for assembling an inner magnet of an aluminum bar of a keyboard, in particular to a jig for assembling a bulk magnet. Background technique [0002] At present, the assembly of multiple magnets in the aluminum rod slot of the keyboard is done manually. The following are the defects and deficiencies: [0003] 1. Defective and scrapped high: due to the need to use quick-glue glue during assembly, when the length, width and height of a single magnet≦6.15*3.10*2.71mm, manual assembly is likely to cause the magnet to reverse, the position is incorrect, and the quick-glue glue After scrapping, the scrap rate is 27%. [0004] 2. Low assembly efficiency: Assemble 20 magnets and 10 spacers in an aluminum rod groove with a length and width of 166.40*3.25mm, and each person assembles 20 pieces per hour. [0005] 3. Poor appearance: because there is quick glue in the groove of the aluminum rod, when the magnet is placed in the wrong...

AI Technical Summary

Problems solved by technology

[0003] 1. Defective and scrapped high: due to the need to use quick-glue glue during assembly, when the length, width and height of a single magnet≦6.15*3.10*2.71mm, manual assembly is likely to cause the magnet to reverse, the position is incorrect, and the quick-glue glue After scrapping, the scrapping rate is 27%

[0004] 2. Low assembly efficiency: Assemble 20 magnets and 10 spacers in an aluminum rod groove with a length and width of 166.40*3.25mm, and each person assembles 20 pieces per hour

[0005] 3. Poor appearance: because there is quick glue in the groove of the aluminum rod, when the magnet is placed in the wrong position, it is easy to make the glue stick to the hand to correct it by hand. When the hand takes the aluminum rod, the aluminum rod product is also stuck to the glue , the defective rate is at 35%

[0006] 4. The overall misalignment is high: the magnets are manually assembled in the aluminum rod groove, because the total length of the aluminum rod groove is longer than the total length of 20 magnets and 10 spacers, the magnet needs to be centered in the groove, but manual assembly cannot be positioned Accurate, resulting in misalignment within 20%
