Description

Nail leakage alarm device of frame assembling machine

Technical Field

The utility model relates to photo frame assembling equipment, in particular to a nail missing alarm device of a frame assembling machine.

Background

There are many photo frame products on the market today for inlaying paintings or photos, etc. The picture frame is generally assembled by splicing several frame plates. The mode of concatenation, some adoption do not glue the mode of the direct nailing of rubber coating, and the easy production of equipment back product bight splits the line: some adopt rubber coating earlier then nailing, glue does not solidify, and the product bight still easily produces the crack line after the equipment: some methods firstly glue and fix the glue by using a rubber band, and then nail is nailed after the glue is cured, so that the method occupies a large area, requires more workers and has low efficacy.

In the existing structure, when a photo frame is generally assembled, an upper pressing plate and a lower pressing plate are arranged, and after the two frame plates are pressed, the two frame plates are nailed through nails. Nails are generally conveyed into the nail through holes from the nail conveying grooves, then the nails are pushed upwards by the ejector rods below, the nails are pushed out of the nail through holes, and then the nails are bound by utilizing the upper pressing block and the lower pressing block. However, in the existing nailing structure, if the brad nails are clamped in the brad nail through holes or no brad nail is arranged in the nail feeding groove, when the nail is lacked, the nailing structure still continues to work, and the problem can not be found, and the structure is that the brad nails are not arranged between two photo frame panels sometimes, so that the quality of products is influenced.

Disclosure of Invention

The utility model provides the nail missing alarm device of the framing machine, which can accurately judge whether the nail feeding through hole is internally provided with the angle nail or not, thereby effectively preventing the nail missing, improving the qualification rate of products and effectively and automatically eliminating the fault; the technical problem that whether the angle nails in the nail through holes exist in the prior art can not be accurately sensed, nails are prone to leaking, and product quality is affected is solved.

The technical problem of the utility model is solved by the following technical scheme: a nail missing alarm device of a framing machine comprises a bottom plate, wherein a nail feeding groove is arranged on the bottom plate, an upper nail block is arranged at the end part of the nail feeding groove, an upper nail through hole is formed in the upper nail block, an ejector rod is arranged in the upper nail through hole and connected with an upper nail driving structure, the upper nail through hole comprises a nail hole main body, nail hole extending grooves are formed in two sides of the nail hole main body, and the ejector rod is connected in the nail hole main body in a penetrating manner; the upper nail block is provided with a mounting hole, an optical fiber sensor is mounted in the mounting hole, the mounting hole is intersected with the upper nail through hole, and the joint of the mounting hole and the upper nail through hole is positioned on the nail hole extending groove. The angle nail is formed by a V-shaped angle nail main body and a flanging turned on the outer side, the shape of the nail through hole is designed by utilizing the structural characteristics of the angle nail, the nail through hole is also formed with a nail hole extending groove, the nail hole extending groove is matched with the flanging of the angle nail, and the optical fiber sensor in the mounting hole is just opposite to the flanging position at the moment, if the nail is normally nailed in the nail through hole, the optical fiber sensor can detect the normal operation of the equipment. When the nail is lacked, because the optical fiber sensor is facing to the turn-ups position, the perception that can be accurate lacks the nail, equipment warning is shut down, the nail state of can not appearing leaking to influence the equipment of photo holder frame. The cross section of the ejector rod is the same as that of the angle nail main body, the ejector rod is not provided with an outward-turned flanging, and the ejector rod moves upwards in the nail hole main body and cannot be sensed by the optical fiber sensor. Therefore, the monitoring precision is not influenced by the movement of the mandril in the upper nail through hole. And the nail feeding mechanism can normally continue to move up and down under the driving of the upper nail driving structure, so that the upper and lower conveying of the brad nails is completed.

Preferably, the mounting hole and the upper nail through hole are arranged in a mutually perpendicular mode, the nail hole main body of the upper nail through hole is quadrilateral, and the nail hole extending grooves are flanged outwards on two adjacent edges of the nail hole main body. The mutual perpendicular is arranged, and the processing is convenient, also makes things convenient for the installation of sensor.

Preferably, the upper end of the ejector rod is provided with two top contact surfaces which are perpendicular to each other, the angle nail comprises an angle nail main body and flanges which are positioned on two sides of the angle nail main body, and the top contact surfaces are connected with the angle nail main body. The contact surface of ejector pin and angle nail only inject in angle nail main part like this, and the ejector pin does not possess turn-ups to correspond the structure, therefore the ejector pin is in last nail through-hole motion, can not influence the accuracy of the monitoring of sensor.

Preferably, a U-shaped positioning surface is formed on the rear side of the upper nail block, the nail feeding groove is abutted to the U-shaped positioning surface, the upper nail through hole is a V-shaped groove in the positioning surface, the nail feeding groove is connected with the V-shaped groove of the upper nail through hole, and the front end surface of the nail feeding groove is in a V shape. The part of the through hole of the upper nail block, which is positioned on the positioning surface, is cut into two parts, a V-shaped groove is formed, and the two sides of the positioning surface of the upper nail block are also in a through hole form. The V-shaped groove is convenient for horizontally connecting the angle nails in the nail feeding grooves, and then the angle nails are upwards fed into the upper nail through holes by utilizing the ejector rods.

Preferably, the upper nail driving structure is a pneumatic driving structure.

Therefore, the nail missing alarm device of the framing machine has the following advantages: set up the nail hole extending groove that corresponds with the turn-ups of angle nail in last nail through-hole, and the shape of ejector pin is only the same with the main part of angle nail, the contact surface of ejector pin and angle nail only inject in angle nail main part like this, the ejector pin does not possess turn-ups correspond the structure, and optical fiber sensor just can pass through difference between the two, correspond the turn-ups position of arranging at the angle nail, thereby whether have the angle nail in can accurately monitoring the last nail through-hole, improve the qualification rate of product, in case lack the nail or leak the nail, in time report to the police, manual work or equipment are automatic to get rid of the trouble.
