Description

Technical Field

[0001] This utility model relates to the field of plastic shell molding technology, specifically to a fiber optic detection head for detecting missing material in nuts. Background Technology

[0002] After the plastic shell is molded, a metal nut is inserted at the location where screws are needed to enhance the tensile strength and durability of the plastic shell screw post.

[0003] However, in the conventional structure of a vertical feeding machine head for inserting metal nuts, when there is a shortage of incoming metal nuts, the equipment continues to work without knowing that there is a shortage, resulting in defective products without inserted metal nuts, which seriously affects the production schedule and defect rate. Utility Model Content

[0004] The purpose of this invention is to provide a fiber optic detection head for detecting missing nuts, in order to solve the problem mentioned in the background art where the equipment is unclear about whether there is a missing nut.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a through-beam fiber optic nut missing material detection head, comprising:

[0006] A fixed plate is provided, with a feeding needle and a metal nut guide tube arranged inside the middle of the fixed plate. A light fixture is fixedly installed on the outer wall of the middle of the fixed plate. Opposite light beams are installed on both sides below the light fixture. A nut heating block is fixedly installed on the inner side of the middle of the light fixture. A heat insulation column is inserted inside the upper part of the nut heating block. A bottom cover is provided on the lower surface of the nut heating block. A feeding nozzle is provided inside the lower middle part of the bottom cover. An electric heating tube is inserted horizontally inside the nut heating block. A cylinder mounting base is fixedly installed at one end of the fixed plate. A pushing cylinder is provided below the cylinder mounting base. A pushing block is fixedly connected to the output end of the pushing cylinder. A detection fiber optic hole is opened inside the pushing block at the end away from the pushing cylinder.

[0007] Preferably, the punching needle penetrates the interior of the fixed plate and is inserted into the nut heating block.

[0008] Preferably, the metal nut guide tube passes through the inside of the fixed plate and is inserted into the nut heating block.

[0009] Preferably, the heat insulation column is fixedly connected to the nut heating block, and the nut heating block is fixedly connected to the bottom cover.

[0010] Preferably, the feeding nozzle extends through the inside of the bottom cover and is inserted into the nut heating block.

[0011] Preferably, the electric heating tube is fixedly connected to the nut heating block, and the pusher block is slidably connected to the nut heating block.

[0012] Preferably, the pushing cylinder is fixedly connected to the cylinder mounting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model's machine head features a special design compared to the original, incorporating a beam beam and a beam fixing component. Metal nuts are fed in batches into the nut heating block via a metal nut guide tube. An electric heating element heats the nut heating block, reaching a maximum temperature of 350℃. The nut heating block heats the metal nuts through thermal conduction. A pusher cylinder and pusher block independently eject each nut, pushing it above the feeding nozzle. Guided by the feeding needle and the feeding nozzle, the metal nuts are accurately inserted into the screw post of the plastic shell. Because the metal nuts are already heated to a high temperature... With the added pressure from the pusher cylinder and ejector pin on the metal nut, the metal nut is easily heat-melted and implanted into the plastic stud. After the metal nut cools, the heat-melted plastic is tightly bonded to the metal nut, thereby increasing the tensile strength of the nut. When there is a shortage of material and no metal nut enters the machine head, the beam of light can quickly detect that the machine head is in a material shortage state, and the machine will stop, alarm, and notify the technician to add material. The screw matched with the implanted metal nut can be repeatedly disassembled and assembled, completely solving the problems of easy stripping of the inner thread of the original plastic stud and insufficient tensile strength.

[0030] Working Principle: In use, metal nuts are first fed in batches through the metal nut guide tube 02 into the nut heating block 07. The electric heating tube 10 heats the nut heating block 07, reaching a maximum temperature of 350℃. The nut heating block 07 heats the metal nuts through heat conduction. The pusher cylinder 12 and pusher block 11 push each nut out independently. The pusher block 11 pushes the metal nut above the discharge nozzle 09. Guided by the ejector needle 01 and the discharge nozzle 09, the metal nut is accurately inserted into the screw stud of the plastic shell. Because the metal nut is already heated to a high temperature, and with the increased pressure from the pusher cylinder 12 and ejector needle 01, the metal nut is easily heat-melted and inserted into the plastic shell screw stud. After the metal nut cools, the heat-melted plastic is tightly bonded to the metal nut. This is the complete working principle of this utility model.
