The slider 12 is then withdrawn so that the printed circuit on the upper portion of the slider 12 is positioned to connect the circuits to form a flexible circuit-like circuit connection in the form of a strip of bendable tabs. At this time, the straight rod 22 for limiting the adjacent single boards is pulled away, so that the two adjacent single boards can be mutually bent, and then the bent single boards are fixed to form the bent circuit main board. Compared with the traditional small mainboard, the mainboard processed by the processing technology can be used for more complex circuit printing without connecting redundant circuits between two electric boards, so that the overall layout of the circuit is more convenient, and the design of the bent circuit mainboard ensures that the overall size of the circuit mainboard is smaller and the layout is more compact.

The adjusting module 2 is suitable for industrial processing, and meanwhile, the processed bent circuit board can be straightened again, so that the circuit board produced by the process is wider in application range.

In the specific design, as shown in fig. 2 and 3, the upper edge of the contact position of the two single boards connected to the substrate 1 is designed as a fillet edge. Thus, after the two single plates of the substrate 1 are bent, the printed board on the upper part of the substrate is smoothly contacted with the corner position of the substrate when the printed board is bent, and the printed board can be protected. In a specific design, when the sliding bar 12 is placed between two single plates of the substrate 1, the upper protruding part of the sliding bar 12 is covered with an insulating release layer 13. The demoulding layer 13 with the sliding strip 12 is in a separated state, can relatively slide in the front and back direction, and after the printed circuit board on the upper portion of the substrate 1, the printed circuit is combined with the demoulding layer 13, so that the printed circuit layer is not tightly adhered to the upper portion of the sliding strip 12, the printed circuit layer is easy to strip, the next step of extraction of the sliding strip 12 is facilitated, meanwhile, the demoulding layer 13 can play a role in insulation and water resistance, oxidation and corrosion of the printed circuit can be effectively prevented, the using effect is better, meanwhile, the demoulding layer 13 can enable the printed circuit to be higher in bending part strength and not easy to break, and the circuit is more stable in use.

In the production process, the sliding strip 12 needs to be extracted, the traditional circuit board production equipment cannot complete the operation, and the patent discloses the production equipment for pushing out and extracting the sliding strip in the fifth step of the circuit board processing process in the right 1. As shown in fig. 6, 7, 8 and 9, the production apparatus includes a horizontal feeding rail 3 for placing and conveying the substrate 1, the substrate 1 is placed on an upper portion of the feeding rail 3, and a push rod module 4 for pushing out the slide bar 12 is mounted on a front portion of the feeding rail 3. The slide bar 12 is made of a rigid material because a certain hardness needs to be maintained. The push rod module 4 comprises a screw rod 41 horizontally fixed through the front part, the screw rod 41 and the sliding bar 12 are coaxially assembled, a moving screw sleeve 42 in threaded connection is wrapped outside the screw rod 41, the rear part of the screw rod 41 penetrates through the rear part of the moving screw sleeve 42, external teeth are machined on the outer side of the front part of the moving screw sleeve 42, a transmission gear 43 is meshed on the external teeth of the moving screw sleeve 42, and the transmission gear 43 is in transmission connection with a power source.

A pressure roller 44 is installed on the outer side of the rear part of the movement wire sleeve 42 through a connecting rod, the pressure roller 44 is pressed on an acting plate 45 at the rear part of the base plate 1, the outer edge of the acting plate 45 is connected with more than two elastic ropes 46 which are uniformly distributed, the acting plate 45 is pulled forwards and tightly pressed on the pressure roller 44 by the elastic ropes 46, a circular bulge 451 is processed at the front part of the acting plate 45, and when the pressure roller 44 rotates along with the movement wire sleeve 42, the pressure roller 44 passes through the bulge 451 at the front end of the acting plate 45; a transmission rod 47 is arranged at the rear part of the acting plate 45, a transmission hole is formed at the rear part of the transmission rod 47, a push rod 48 capable of sliding back and forth is arranged in the transmission hole, the front part of the push rod 48 is connected with the front part of the transmission hole through a spring 49, and the push rod 48 is coaxially assembled with the screw rod 41; a press roller 5 with an axis parallel to the sliding strip 12 is assembled on the upper part of the sliding strip 12, the press roller 5 can rotate around a shaft, an elastic pressing material layer is wrapped on the surface of the press roller 5, and the press roller 5 is elastically pressed on the upper part of the substrate 1 through the pressing material layer; when the substrate 1 moves horizontally on the feeding track 3, the pressing roller 5 rotates synchronously, while the lower part of the pressing roller 5 keeps pressing the printed circuit on the upper part of the substrate 1, and when the sliding strip 12 part of the substrate 1 moves to the lower part of the pressing roller 5, as shown in fig. 9, the pressing layer of the pressing roller 5 presses the printed circuit at the substrate bending position and the sliding strip 12 elastically.

The rear part of the feeding track 3 is provided with paired discharging wheels 6, the axes of the discharging wheels 6 are in transmission connection with a power module, pressing grooves 61 are machined on the outer rings of the discharging wheels 6, the outer rings of the discharging wheels 6 are made of elastic materials, the pressing grooves 61 of the paired discharging wheels 6 are over against the axial position of the sliding strip 12, when the sliding strip 12 is ejected, the front part of the sliding strip 12 extends into the pressing grooves 61 of the paired discharging wheels 6, and the pressing grooves 61 of the two discharging wheels 6 elastically press the sliding strip 12. This pushes the slide bar 12 forward during the rotational movement of the outlet wheel 6.

When the production equipment for pushing out and extracting the sliding strip is used, the substrate 1 and the sliding strip 12 are fixed through the compression roller 5, at this time, the sliding strip 12 is over against the ejector rod 48, before the sliding strip 12 is pushed out, as shown in fig. 7, the ejector rod 48 is positioned in front of the sliding strip 12, when the transmission gear 43 rotates, the moving wire sleeve 42 is driven to rotate, and due to the limiting of the screw rod 41, the moving wire sleeve 42 moves backwards. While the pressure roller 44 at the rear of the moving wire package 42 follows. Since the pressure roller 44 continuously passes through the protrusion 451 at the front end of the acting plate 45 during the rotation process, the pressure roller 44 makes the acting plate jump back and forth while pushing the acting plate 45 to move backward as a whole. This drives the ejector pin 48 to knock the slide bar 12, and due to the action of the spring 49, the knocking of the ejector pin 48 on the slide bar 12 is elastic knocking, which not only makes the slide bar 12 detachable from the printed circuit, but also pushes the slide bar 12 out toward the rear. In addition, the printed circuit is ensured to be stably connected in the process of separating from the sliding strip 12 due to the elastic compression of the pressing material layer outside the pressing roller 5 on the printed circuit. The sliding strip 12 knocked out of the substrate 1 backwards enters the pressing grooves 61 symmetrically arranged on the discharging wheels 6, as shown in fig. 8, at this time, the discharging wheels 6 designed at the rear part of the feeding track 3 synchronously rotate, and the sliding strip is extracted backwards through the pressing grooves 61 symmetrically arranged on the feeding track until the sliding strip is completely extracted, so that the whole extraction process is completed. The discharging wheel 6 is designed for the sliding strip 12 extraction structure, so that the equipment can extract the sliding strip 12 from the wide substrate 1, and the process is wider in suitable range.

In a specific design, as shown in fig. 7 and 8, the rear part of the feeding track 3 is provided with more than two pairs of discharging wheels 6. This provides a better extraction of the slide bar 12. The movement of the slide bar 12 is more stable during the process of being withdrawn. More than two pressure rollers 44 which are uniformly distributed relative to the axis of the movement wire sleeve 42 are arranged on the outer side of the rear part of the movement wire sleeve 42 through connecting rods, and bulges 451 with the same number as the pressure rollers 44 are uniformly distributed on the front part of the acting plate 45. In this embodiment, the number of the rollers 44 and the protrusions 451 is two, so that when the moving wire sleeve 42 drives the pressure roller 44 to rotate, the stress is more balanced, and at the same time, each time the moving wire sleeve 42 rotates for one circle, the acting plate 45 and the ejector rod 48 can be driven to vibrate twice, so that the ejection vibration frequency of the ejector rod 48 is higher, and the ejection effect is better.
