Description

Technical Field

[0001] The utility model relates to the technical field of electronic component taping machines, in particular to a taping and punching device of an electronic component taping machine. Background Art

[0002] Electronic components with pins (such as capacitors, resistors, etc.) can be taped with paper tape and adhesive tape, which is convenient for packaging and storage of electronic components; and in order to cooperate with the needle wheel of the taping equipment and the customer's feeding equipment, it is necessary to use a punching mechanism to punch holes on the tape so that the punched circular holes are located between two electronic components, thereby guiding the product to move at a fixed distance, so that the customer's feeding equipment can accurately locate and cut the product on the tape and insert it into the circuit board, thereby realizing automated production.

[0003] An automatic taping machine is an automated equipment commonly used for taping electronic components. For example, the Chinese utility model with the authorization announcement number "CN211766507U", the authorization announcement date "October 27, 2020", and the name "Automatic taping machine for electronic components without cylinder drive", the automatic taping machine for electronic components includes a component feeding mechanism, an adjustment mechanism, a cam transmission mechanism, a component taping mechanism and a punching mechanism, wherein the component taping mechanism is located on the discharge side of the pin spacing trimming device, the component taping mechanism includes a taping wheel seat, a guide wheel and two taping wheels, the guide wheel and the taping wheel are respectively installed on the taping wheel seat, the two taping wheels are arranged side by side, and the guide wheel is located on one side of the taping wheel; the punching mechanism includes a material channel seat and a punching needle, the punching needle is movably installed on the material channel seat, and the tail end of the punching needle is transmission-connected to the cam transmission mechanism and driven by it to move back and forth in a direction perpendicular to the feeding direction. During operation, the paper tape and the adhesive tape are guided between the two tape sticking wheels by the guide of the tape guide wheel, and the two pins of the electronic component with the trimmed spacing are attached between the paper tape and the adhesive tape by utilizing the rolling friction pressure between the two tape sticking wheels; then the punching needle is driven back and forth in a direction perpendicular to the feeding direction by the cam transmission mechanism to punch holes on the tape so that the punched circular holes are located between the two electronic components.

[0004] However, this rolling pressing taping method using two taping wheels is generally only suitable for electronic components with a pin pitch of ≤10mm. Electronic component products with large pin pitches will have deviations in the taping position due to the problem of insufficient curvature of the taping wheels. Although the problem of deviation in the taping position can be solved by replacing the taping wheels with larger sizes, the larger taping wheels will also occupy the installation space and have additional design requirements for the additional processing space of the base; moreover, this punching mechanism uses a single punching method, and burrs are easily generated on the edge of the circular hole during punching. The burrs will change the diameter or shape of the circular hole, making the actual size of the circular hole inconsistent with the design size, resulting in the electronic components on the tape being unable to be properly aligned during installation, which can easily cause the electronic component products to be skewed.

[0009] During operation, the paper tape and the adhesive tape are introduced into the tape sticking channel respectively, and then the two pins of the electronic component are also moved into the tape sticking channel through the peripheral component handling equipment, so that the two pins of the electronic component are between the paper tape and the adhesive tape, and then the sliding seat is driven to move leftward by the reciprocating translation mechanism, driving the tape sticking pressing block to press against the tape sticking positioning block, so that the two pins of the electronic component are stuck between the paper tape and the adhesive tape, and the tape that has been taped continues to be transported backward to the punching channel; while the reciprocating translation mechanism drives the sliding seat to move leftward, it also drives the primary punching needle to move leftward in the first guide through hole, and the secondary punching needle to move leftward in the second guide through hole, so that the primary punching needle and the secondary punching needle punch the tape in the punching channel, the primary punching needle punches the tape once to form a round hole on the tape, and as the tape continues to be transported backward, the secondary punching needle punches the existing round hole on the tape for a second time, which can prevent burrs from being generated on the edge of the round hole, and improve the punching quality and the yield rate of the tape.

[0010] In a preferred embodiment, the punching guide seat includes a punching positioning block and a guide positioning block. The punching positioning block and the guide positioning block are installed side by side on the base. The punching channel is formed between the punching positioning block and the guide positioning block.

The primary punching needle 6 punches the braid 9 once to form a circular hole 93 on the braid 9. As the braid 9 continues to be transported backward, the secondary punching needle 7 punches the existing circular hole 93 on the braid 9 for a second time, which can prevent burrs from forming on the edge of the circular hole 93, thereby improving the punching quality and the yield rate of the braid 9.

[0029] The punching guide seat 4 includes a punching positioning block 42 and a guide positioning block 43.
