Description

Technical Field

[0001] This utility model belongs to the technical field of coating and developing machines, specifically an adjustable glue spraying device for coating and developing machines. Background Technology

[0002] A photoresist coating and developing machine is a widely used piece of equipment in the electronics manufacturing industry, particularly in the production of printed circuit boards (PCBs). Its main function is to uniformly coat photoresist or photosensitive adhesive onto the substrate surface and then reveal the photoresist pattern through a developing process. A photoresist coating and developing machine typically consists of multiple steps, including coating, exposure, developing, and drying. During its normal operation, adhesive needs to be applied to the substrate, which requires the use of a corresponding adhesive spraying device.

[0003] Conventional glue spraying devices mainly consist of a glue supply device and a glue spraying device. The glue enters the glue spraying tube through the glue supply tube and is sprayed out. However, in the actual spraying process, the angle of the glue spraying tube needs to be adjusted accordingly. In the existing technology, the angle adjustment is generally achieved by bending the corrugated tube. This angle adjustment method has a limited range of angle adjustment and poor stability, and urgently needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable glue spraying device for a glue coating and developing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable glue spraying device for a glue coating and developing machine, comprising a glue supply hose, a spherical mounting base fixedly connected to the front end of the glue supply hose, a rotating ball seat movably mounted to the front end of the spherical mounting base, the rotating ball seat rotating relative to the spherical mounting base, a material inlet opening in the middle of the rotating ball seat, a glue spraying pipe fixedly connected to the front end of the rotating ball seat, the glue spraying pipe communicating with the material inlet, a mounting plate fixedly sleeved on the outer side of the spherical mounting base, a locking sleeve fixedly sleeved on the outer side of the glue spraying pipe near the rotating ball seat, an annular limiting guide rail opening on the front of the mounting plate, an adjustment component provided between the annular limiting guide rail and the locking sleeve, the adjustment component being used to adjust the distance between the annular limiting guide rail and the locking sleeve.

[0006] Before use, the glue delivery hose can be connected to the external glue delivery pipeline, and a certain pressure can be maintained when the glue is input. The pressurized glue can be input into the glue delivery hose through the external glue delivery pipeline, and enter the inside of the delivery port through the ball mounting seat, and then be discharged through the glue spraying tube to complete the glue spraying process.

[0007] As a further technical solution of this utility model, an annular limiting block is movably engaged with the front of the annular limiting guide rail, the annular limiting block rotates relative to the annular limiting guide rail, and an extension plate is fixedly installed on the front of the annular limiting guide rail.

[0008] As a further technical solution of this utility model, a handle is fixedly installed at the top of the extension plate, and the annular limiting block rotates along the central axis of the mounting plate.

[0009] When the handle is pulled and the extension plate and the annular limit block are rotated relative to the annular limit guide rail, the adjustment component on the front can be rotated along the central axis of the mounting plate, and a pulling force is applied to the glue spray tube at the bottom. At this time, the glue spray tube can also maintain the current deflection angle and rotate relative to the central axis of the mounting plate, changing the deflection of the glue spray tube from the downward angle to other angles, completing a large-range adjustment process, improving the adjustable range of the glue spray tube, and improving glue spraying efficiency.

[0010] As a further technical solution of this utility model, the adjustment component includes two mounting seats, which are respectively connected to the middle of the top of the locking sleeve and the middle of the front of the extension plate. The adjustment component also includes a fixing sleeve located between the two mounting seats.

[0011] As a further technical solution of this utility model, both the upper and lower ends of the fixed sleeve are movably sleeved with movable plates, and movable rods are fixedly installed at the ends of the two movable plates that are relatively far apart. The movable plates move up and down relative to the fixed sleeve.

[0012] As a further technical solution of this utility model, the end of the movable rod away from the movable plate passes through one end of the fixed sleeve and is fixedly installed with a movable ear plate, and the movable ear plate is connected to the mounting base through a rotating shaft.

[0013] As a further technical solution of this utility model, when the glue spraying tube and the glue delivery hose are parallel to each other, the distance between the two movable plates is at its minimum value, and the overall length of the adjustment component is at its shortest state.

[0014] By rotating the glue spray tube directly downwards, the rotating ball seat rotates relative to the spherical mounting base. This changes the relative position of the rotating ball seat and the spherical mounting base, causing the locking sleeve to deflect diagonally downwards and apply tension to the top mounting base and the movable ear plate. This causes the two movable plates to shift relative to each other, increasing the distance between them. The upper movable ear plate rotates synchronously relative to the mounting base, completing the overall length adjustment of the adjustment component. When the glue spray tube is no longer rotated, the length of the adjustment component remains fixed, completing the angle locking process of the glue spray tube. This enables rapid adjustment of the glue spray tube angle, avoiding the poor stability problem of traditional corrugated pipe angle adjustment.

[0015] The beneficial effects of this utility model are as follows: (1) By rotating the glue spray tube directly downwards, the rotating ball seat can be rotated relative to the spherical mounting seat. At this time, the relative position of the rotating ball seat and the spherical mounting seat changes accordingly. At the same time, the locking sleeve deflects obliquely downwards and applies a pulling force to the mounting seat and movable ear plate at the top. At this time, the two movable plates are displaced relative to each other, and the distance between the two movable plates increases accordingly. The movable ear plate located above rotates synchronously relative to the mounting seat, completing the overall length adjustment of the adjustment component. When the glue spray tube is no longer rotated, the length of the adjustment component is kept fixed, completing the angle locking process of the glue spray tube, realizing the rapid adjustment of the angle of the glue spray tube, and avoiding the problem of poor stability of the traditional corrugated pipe angle adjustment.

[0016] (2) When the handle is pulled and the extension plate and the annular limiting block are rotated relative to the annular limiting guide rail, the front adjustment component can be rotated along the central axis of the mounting plate and a pulling force is applied to the bottom spray tube. At this time, the spray tube can also maintain the current deflection angle and rotate relative to the central axis of the mounting plate, changing the deflection of the spray tube from the oblique downward to other angles, completing the large-range adjustment process, improving the adjustable range of the spray tube and improving the spraying efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown in the embodiment of this utility model, an adjustable glue spraying device for a glue coating and developing machine includes a glue supply hose 1, a spherical mounting base 2 fixedly connected to the front end of the glue supply hose 1, a rotating ball seat 3 movably mounted to the front end of the spherical mounting base 2, the rotating ball seat 3 rotating relative to the spherical mounting base 2, a material inlet 4 opening in the middle of the rotating ball seat 3, a glue spraying pipe 5 fixedly connected to the front end of the rotating ball seat 3, the glue spraying pipe 5 communicating with the material inlet 4, a mounting plate 7 fixedly sleeved on the outer side of the spherical mounting base 2, a locking sleeve 6 fixedly sleeved on the outer side of the glue spraying pipe 5 near the rotating ball seat 3, an annular limiting guide rail 8 opening on the front of the mounting plate 7, an adjustment component 12 provided between the annular limiting guide rail 8 and the locking sleeve 6, the adjustment component 12 being used to adjust the distance between the annular limiting guide rail 8 and the locking sleeve 6.

[0021] Before use, the glue delivery hose 1 can be connected to the external glue delivery pipeline, and a certain pressure can be maintained when the glue is input. The pressurized glue can be input into the glue delivery hose 1 through the external glue delivery pipeline, and enter the inside of the material inlet 4 through the ball mounting seat 2, and be discharged through the glue spraying pipe 5 to complete the glue spraying process.

[0022] like Figure 1 and Figure 4 As shown, an annular limiting block 9 is movably engaged on the front of the annular limiting guide rail 8. The annular limiting block 9 rotates relative to the annular limiting guide rail 8. An extension plate 10 is fixedly installed on the front of the annular limiting guide rail 8. A handle 11 is fixedly installed on the top of the extension plate 10. The annular limiting block 9 rotates along the central axis of the mounting plate 7.

[0023] When the handle 11 is pulled and the extension plate 10 and the annular limiting block 9 are rotated relative to the annular limiting guide rail 8, the adjustment component 12 on the front can be rotated along the central axis of the mounting plate 7, and a pulling force is applied to the glue spray tube 5 at the bottom. At this time, the glue spray tube 5 can also maintain the current deflection angle and rotate relative to the central axis of the mounting plate 7, changing the deflection of the glue spray tube 5 from the downward angle to other angles, completing a large-range adjustment process, improving the adjustable range of the glue spray tube 5, and improving the glue spraying efficiency.

[0024] like Figure 1 and Figure 4 as well as Figure 5As shown, the adjustment assembly 12 includes two mounting bases 121, which are respectively connected to the middle of the top of the locking sleeve 6 and the middle of the front of the extension plate 10. The adjustment assembly 12 also includes a fixed sleeve 123 located between the two mounting bases 121. Movable plates 125 are movably sleeved at both the upper and lower ends of the fixed sleeve 123. Movable rods 124 are fixedly installed at the ends of the two movable plates 125 that are relatively far apart. The movable plates 125 move up and down relative to the fixed sleeve 123. The ends of the movable rods 124 that are far away from the movable plates 125 pass through one end of the fixed sleeve 123 and are fixedly installed with movable ear plates 122. The movable ear plates 122 are connected to the mounting bases 121 by a rotating shaft. When the glue spraying tube 5 and the glue delivery hose 1 are parallel to each other, the distance between the two movable plates 125 is at its minimum value, and the overall length of the adjustment assembly 12 is at its shortest state.

[0025] By rotating the glue spray tube 5 directly downwards, the rotating ball seat 3 rotates relative to the spherical mounting seat 2. This changes the relative position of the rotating ball seat 3 and the spherical mounting seat 2, causing the locking sleeve 6 to deflect diagonally downwards and apply tension to the top mounting seat 121 and the movable ear plate 122. This causes the two movable plates 125 to shift relative to each other, increasing the distance between them. The upper movable ear plate 122 rotates synchronously relative to the mounting seat 121, completing the overall length adjustment of the adjusting assembly 12. When the glue spray tube 5 is no longer rotated, the length of the adjusting assembly 12 remains fixed, completing the angle locking process of the glue spray tube 5. This achieves rapid angle adjustment of the glue spray tube 5, avoiding the problem of poor stability in traditional corrugated pipe angle adjustment.

[0026] Working principle and usage process: Before use, the glue delivery hose 1 can be connected to the external glue delivery pipe, and a certain pressure can be maintained when the glue is input. The pressurized glue can be input into the glue delivery hose 1 through the external glue delivery pipe, and enter the inside of the material inlet 4 through the ball mounting seat 2, and be discharged through the glue spraying pipe 5 to complete the glue spraying process. When the handle 11 is pulled and the extension plate 10 and the annular limit block 9 are rotated relative to the annular limit guide rail 8, the adjustment component 12 on the front can be rotated along the central axis of the mounting plate 7, and a pulling force is applied to the glue spray tube 5 at the bottom. At this time, the glue spray tube 5 can also maintain the current deflection angle and rotate relative to the central axis of the mounting plate 7, changing the deflection of the glue spray tube 5 from the downward angle to other angles, thus completing the large-range adjustment process. Rotating the glue spray tube 5 directly downwards causes the rotating ball seat 3 to rotate relative to the spherical mounting seat 2. This changes the relative position of the rotating ball seat 3 and the spherical mounting seat 2. Simultaneously, the locking sleeve 6 deflects diagonally downwards, applying tension to the top mounting seat 121 and the movable ear plate 122. This causes the two movable plates 125 to shift relative to each other, increasing the distance between them. The upper movable ear plate 122 rotates synchronously relative to the mounting seat 121, completing the overall length adjustment of the adjustment component 12. When the glue spray tube 5 is no longer rotated, the length of the adjustment component 12 remains fixed, completing the angle locking process of the glue spray tube 5.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
