Abstract

The utility model relates to a board supporter for a continuous dryer, which is arranged on a conveying belt of the continuous dryer and used to receive and send a circuit board. The surfaces of the board supporter are all bent toward the center, and thus the center position forms an obtuse angle shape. When the circuit board leans against the surface of the board supporter, the upper endpoint and the lower endpoint of the circuit board are contacted with the surface of the board supporter, and thus the board surface of the circuit board can not be scored by the board supporter. The board supporter is composed of a main support and a slave support, wherein one end of the main support is fixed to the conveying belt of the continuous dryer, and the other end is inclined upwards to bend from the center position, which makes the center position of the first surface of the main support form an obtuse angle; the slave support is arranged on the second surface of the main support, and the slave support and the main support form incline bending, which makes the center position of the second surface of the main support also form an obtuse angle. When the circuit board leans against the first surface of the board supporter or the second surface of the adjacent board supporter, namely that the end edges are contacted with the board supporter, the board surface, etc. of the circuit board can not be scored.

Description

The grillage device of continuous drier

The utility model relates to a kind of grillage device, is meant a kind of continuous drier that is used to toast dry circuit board especially, makes circuit board in dry transmission course, the unlikely grillage device of being scraped the continuous drier that decreases circuit board plate face by grillage.

The general circuit plate must be toasted the anti-welding edge lacquer on the circuit board by continuous drier in manufacture process is dried to suitable softness, then by the folding and unfolding of grillage the circuit board transmission is transported in automated job, to reach the effect of continuous drying circuit board.

The grillage device of traditional continuous drier, as shown in Figure 1, grillage 1 bottom is provided with opening U type groove 10 up, and its top then is provided with hack lever 11, the bottom of grillage 1 is fixed on the conveyer belt 20 of continuous drier 2 with U type groove 10 two ends, can be transferred to be with 20 to carry back and forth rotation.As shown in Figure 2, suitable to several grillages 1 that promptly are provided with side by side on the conveyer belt 2 every one, toast drying by the grillage on the conveyer belt 20 1 with circuit board for receiving 21, circuit board 21 1 ends are fallen in the U type groove 10 of grillage 1, and along with the rotation of conveyer belt 20, grillage 1 is about to be propped up in conveyer belt receiving terminal 201 places circuit board 21 is done rotation and is driven, and drives forward after propping up and toasts; Broadcast end 202 the time when circuit board 21 is sent to, can be pushed the vertical direction of overturning, circuit board 21 will be against living and grillage 1 previous adjacent another grillage 1 of establishing.As shown in Figure 3, form transmission.Circuit board 21 is to contact with the hack lever 11 of grillage 1 with whole plate face in transport process, and therefore the plate face of circuit board 21 is arrived in scratch easily, and forms defective products.

The grillage device of another kind of continuous drier, as shown in Figure 4, grillage 3 central appropriate positions are provided with a kink 30 to bending, make it when accessing circuit board 31, circuit board 31 only contacts with its bottom 32 and 33 two bridges with grillage 3 in top, therefore the plate face can be by grillage 3 scratches, and can improve the deficiency of above-mentioned grillage, again this kind plate add 3 in circuit board 31 course of conveying the end 20 o'clock, circuit board 31 central parts will contact with kink 30 back sides of grillage 3, the plate face that also will form circuit board 31 is by the situation of scratch, as shown in Figure 5.

The purpose of this utility model is to provide a kind of grillage device with unlikely scratch to the continuous drier of circuit board plate face.

The purpose of this utility model is achieved in that the positive back side of grillage bends to central authorities, make the positive back side middle position of hack lever form the obtuse angle shape, and when circuit board when being located at the pole face of grillage, contact with the hack lever face of grillage with its upper/lower terminal edge no matter the front and back of plate face are all permanent, can make the plate face of the unlikely scratch of grillage to circuit board.

Grillage of the present utility model is made up of body frame and subframe, main adding on the conveyer belt that an end is fixed in continuous drier, the bending that is inclined upwardly of other end central part, make first central part of body frame slightly be bent to form the obtuse angle, and subframe is located on second of body frame, and with the body frame bending of forming, and make body frame second and middle position also forms the obtuse angle, when circuit board is gone up by being located at first of grillage or adjacent grillage second, also only be that end points contacts with grillage, and unlikely scratch is to the plate face of circuit board.

The utlity model has following advantage: reasonable in design, simple in structure, grillage can the scratch circuit board or the like.

The drawing of accompanying drawing is described as follows:
