Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically to an automatic adhesive coating and curing device for PCB boards. Background Technology

[0002] The PCB automatic glue application and curing device is an industrial equipment that combines automated control, precision glue application, and rapid curing. It is mainly used to automatically dispense and coat glue onto specific components or areas during the PCB (printed circuit board) manufacturing process and cure it immediately to improve production efficiency and ensure consistent glue application quality.

[0003] Existing automatic PCB board adhesive application and curing devices can be referenced from Chinese Utility Model Patent Publication No. CN 220697275U, which discloses a PCB board processing adhesive application and curing machine. The machine includes a processing table with a protective cover mounted on its upper side and an ultraviolet lamp mounted on the lower side of the protective cover. It also includes a motor mounted on the right front of the processing table, with its output end connected to a pulley. The pulley and processing table are rotatably connected, and a conveyor belt is attached to the outer side of the pulley, with a placement seat mounted on the outer side of the conveyor belt. A fixed suction cup is mounted on the upper side of the placement seat. This PCB board processing adhesive application and curing machine features a fixed suction cup and a fixed plate. The placement seat moves the PCB board above it. During movement, the fixed plate pushes an adjusting rod, which, in conjunction with the driving of the connecting rod and the moving rod, controls the piston movement, adjusting the air pressure inside the fixed suction cup. This allows the fixed suction cup to apply negative pressure to the PCB board, ensuring the stability of the PCB board transport and curing process.

[0004] The above-mentioned device has good performance, but there are still some defects in its actual use: When using the PCB board to process the dispensing and curing machine, the entire device is placed stably in the working area, the PCB board is placed on the placement seat, the conveyor belt is controlled to move and transport the PCB board to the right, and the ultraviolet lamp is used to irradiate and cure the PCB board. However, the ultraviolet lamp is fixedly set on the top of the inner wall of the protective cover, and the vertical distance between the ultraviolet lamp and the PCB board on the top of the conveyor belt is not adjustable. Different PCB boards may carry components of different heights. If the height of the ultraviolet lamp is fixed, the equipment can only be used for single or similar products, which limits the versatility of the equipment. Utility Model Content

The two U-shaped plates slide from the left and right sides of the protective cover towards its center. The tops of the two U-shaped plates are slidably connected to the top of the inner wall of the protective cover. Moving grooves, parallel to the length direction of the conveyor belt, are opened at the center of the left and right sides of the top of the protective cover. Two horizontally displaced moving blocks are provided on the left and right sides of the top of the protective cover. The two moving blocks slide from the left and right sides of the protective cover towards its center. A controller for controlling the entire equipment is fixedly connected to the center of the front surface of the processing table.

[0007] As a preferred embodiment of this utility model, a first motor is fixedly connected to the front right side of the processing table, and pulleys are rotatably connected to both the left and right sides inside the conveyor belt, with the two pulleys respectively rotatably arranged on the left and right sides inside the processing table.

[0008] In a preferred embodiment of this invention, the two pulleys are rotatably connected at their front and rear ends to the processing table on opposite sides, and the output shaft of the first motor is fixedly connected to the front end of the right pulley.

[0009] As a preferred embodiment of this utility model, a positioning shell is fixedly connected to the center of the top of the protective cover, and vertically arranged electric telescopic rods are fixedly connected to the bottom of the two movable blocks. The telescopic ends of the two electric telescopic rods extend to the lower part of the interior of the protective cover and are fixedly connected to a U-shaped plate. The surfaces of the two electric telescopic rods are slidably connected to the inner walls of the two movable slots. Positioning plates are fixedly connected to the left and right sides of the top of the protective cover.

[0010] As a preferred embodiment of this utility model, the positioning shell is rotatably connected to horizontal threaded rods on both the left and right sides. The threads of the two horizontal threaded rods are opposite in direction. The surfaces of the two horizontal threaded rods are threadedly connected to the inner walls of the two moving blocks respectively. The ends of the two horizontal threaded rods that are far apart from each other are rotatably connected to the sides of the two positioning plates that are close to each other. The ends of the two horizontal threaded rods that are close to each other extend into the interior of the positioning shell and are rotatably connected thereto.

[0011] As a preferred embodiment of this utility model, horizontally arranged guide rods are fixedly connected to both the left and right sides of the outer side of the positioning shell. The two guide rods are arranged parallel above the two horizontal threaded rods. The two guide rods are slidably connected to the two moving blocks respectively. The side of the two guide rods away from the positioning shell is fixedly connected to the side of the two positioning plates that are close to each other. A horizontally arranged driven bevel gear is fixedly connected to one end surface of the two horizontal threaded rods located inside the positioning shell.

[0012] In a preferred embodiment of this utility model, a power bevel gear ring is rotatably connected to the lower part of the positioning shell. The bottom of the power bevel gear ring is rotatably connected to the center of the top of the protective cover. The left and right sides of the top of the power bevel gear ring are perpendicularly meshed with the bottoms of the two driven bevel gears. A power bevel gear is meshed with the rear side of the top of the power bevel gear ring and is perpendicularly arranged thereto. A second motor is fixedly connected to the rear side of the top of the protective cover. The output shaft of the second motor is fixedly connected to the inner wall of the power bevel gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model involves placing the PCB board to be processed on a placement seat, then connecting the first motor to the power supply, controlling its output end to drive the right pulley to rotate clockwise, thereby driving the conveyor belt to run, so that the placement seat and the PCB board on it are smoothly transported to the right. When the PCB board enters the inner area of ​​the protective cover with the conveyor belt, the ultraviolet lamp is connected to the power supply and begins to emit ultraviolet light to irradiate the UV adhesive coated on the surface of the PCB board, realizing online curing. In the whole process, the PCB board completes the curing process while being transported, which improves production efficiency and operation continuity.

[0014] 2. When the second motor rotates forward, the two moving blocks move closer to each other from the left and right sides of the protective cover towards the center, causing the electric telescopic rod, U-shaped plate and ultraviolet lamp below to retract synchronously. When the second motor rotates in reverse, the two moving blocks move away from each other from the center to the left and right sides, causing the two ultraviolet lamps to unfold. This achieves bidirectional adjustment of the horizontal spacing of the ultraviolet lamps, adapting to the curing needs of different widths or irregularly shaped areas.

[0015] 3. This utility model controls two electric telescopic rods through a controller. When the electric telescopic rods extend downwards, they drive the U-shaped plate and the ultraviolet lamp on it to gradually approach the PCB board surface, increasing the illuminance intensity. When they retract upwards, they increase the distance. The vertical adjustment function effectively solves the problem of uneven curing caused by differences in PCB thickness or component height, and improves the equipment's adaptability to a variety of products.

[0022] Reference Figure 1-3 This is the first embodiment of the present invention, which provides an automatic PCB board adhesive coating and curing device, including a processing table 1 and a protective cover 2 fixedly installed at the center of its top. A conveyor belt 6 arranged parallel to the length direction of the processing table 1 is rotatably connected between the processing tables 1 on their adjacent sides. A plurality of placement seats 7 are equidistantly arranged on the surface of the conveyor belt 6. Furthermore, the lower left and right sides of the interior of the protective cover 2 are provided with U-shaped plates 301 arranged parallel to the width direction of the processing table 1. Ultraviolet lamps 3, arranged parallel to the width direction of the conveyor belt 6, are fixedly connected between the front and rear inner walls of the two U-shaped plates 301. The two U-shaped plates 301 slide from the left and right sides of the protective cover 2 toward its center. The top of the two U-shaped plates 301 is slidably connected to the top of the inner wall of the protective cover 2. The center of the left and right sides of the top of the protective cover 2 is provided with moving grooves 201 arranged parallel to the length direction of the conveyor belt 6. The left and right sides of the top of the protective cover 2 are provided with two horizontally displaced moving blocks 205. The two moving blocks 205 slide from the left and right sides of the protective cover 2 toward its center. The center of the front surface of the processing table 1 is fixedly connected with a controller 17 that controls the entire equipment.

[0023] Specifically, an automatic PCB board adhesive coating and curing device includes a processing table 1 and a protective cover 2 fixedly installed at the center of its top. A conveyor belt 6, parallel to the length of the processing table 1, is rotatably connected between the adjacent sides of the processing table 1. Multiple placement seats 7 are equidistantly arranged on the surface of the conveyor belt 6 to support the PCB boards to be processed. U-shaped plates 301 are provided on the lower left and right sides inside the protective cover 2. The two U-shaped plates 301 slide along the left and right sides of the protective cover 2 towards its center, and their extension direction is parallel to the width direction of the processing table 1. Ultraviolet lamps 3 are fixedly connected between the front and rear inner walls of the two U-shaped plates 301. The extension direction of the ultraviolet lamps 3 is parallel to the width direction of the conveyor belt 6, and they are used to irradiate the PCB boards passing beneath them during the conveying process with ultraviolet light to achieve… To facilitate rapid curing of the adhesive and enable lateral sliding adjustment of the U-shaped plate 301 within the protective cover 2, a movable groove 201 is provided at the center of the left and right sides of the top of the protective cover 2. The extension direction of the movable groove 201 is parallel to the length direction of the conveyor belt 6, allowing the U-shaped plate 301 to be adjusted horizontally. At the same time, two horizontally movable blocks 205 are provided on the left and right sides of the top of the protective cover 2. The two movable blocks 205 also slide along the left and right sides of the protective cover 2 towards its center and are connected to the U-shaped plate 301 to drive the lateral movement of the U-shaped plate 301, thereby adjusting the lateral coverage of the ultraviolet lamp 3 to adapt to the curing requirements of PCB boards of different sizes. A controller 17 is fixedly connected to the center of the front surface of the processing table 1 to control the entire equipment to achieve automated operation.

[0024] Furthermore, the structures such as the fixed suction cup, fixed plate, air groove, piston, moving rod, spring, adjusting rod, connecting rod, and through groove have all been disclosed in the reference patent and are not improvements of this design, so they will not be described in detail here. When using this PCB board to process the dispensing and curing machine, the PCB board is placed on the placement seat 7, the conveyor belt 6 is controlled to move, and the PCB board is transported to the right. The ultraviolet lamp 3 irradiates and cures the PCB board. When the placement seat 7 gradually moves into the protective cover 2, the adjusting rod can be squeezed due to the obstruction of the fixed plate. The piston slides in the air groove to adjust the air pressure in the fixed suction cup, so that the fixed suction cup adsorbs the PCB board under negative pressure, ensuring the stability of the PCB board transportation and curing process. Example

[0025] In the second embodiment of this utility model, a first motor 4 is fixedly connected to the front right side of the processing table 1, and pulleys 5 are rotatably connected to both the left and right sides inside the conveyor belt 6. The two pulleys 5 are respectively rotatably arranged on the left and right sides inside the processing table 1.

[0026] Furthermore, the two pulleys 5 are rotatably connected to the processing table 1 at their front and rear ends respectively, and the output shaft of the first motor 4 is fixedly connected to the front end of the right pulley 5.

[0027] Specifically, a first motor 4 is fixedly connected to the front right side of the processing table 1 to provide power to the conveying structure. Pulleys 5 are rotatably connected to both the left and right sides inside the conveyor belt 6. The two pulleys 5 are respectively located on the left and right sides inside the processing table 1 and are rotatably connected to each other on the side that is close to the processing table 1 in the front-back direction, ensuring that the pulleys 5 can rotate stably and drive the conveyor belt 6 to run smoothly. The front end of the right pulley 5 is fixedly connected to the output shaft of the first motor 4. When the first motor 4 starts, its output shaft drives the right pulley 5 to rotate. Through the transmission action of the conveyor belt 6, the left pulley 5 is synchronously driven to rotate, thereby realizing the continuous clockwise operation of the conveyor belt 6.

[0028] Furthermore, the PCB board is placed from the left onto the placement seat 7. The first motor 4 is powered on, and the pulley 5 connected to the output end is rotated clockwise, thereby controlling the conveyor belt 6 to move and drive the PCB board on the placement seat 7 to be conveyed to the right. After passing through the protective cover 2, the ultraviolet lamp 3 is powered on, and the ultraviolet lamp 3 irradiates and cures the PCB board. Example

[0029] In the third embodiment of this utility model, a positioning shell 202 is fixedly connected to the center of the top of the protective cover 2, and two vertically arranged electric telescopic rods 302 are fixedly connected to the bottom of the two moving blocks 205. The telescopic ends of the two electric telescopic rods 302 extend to the lower part of the interior of the protective cover 2 and are fixedly connected to a U-shaped plate 301. The surfaces of the two electric telescopic rods 302 are slidably connected to the inner walls of the two moving grooves 201. Positioning plates 203 are fixedly connected to the left and right sides of the top of the protective cover 2.

[0030] Furthermore, horizontal threaded rods 204 are rotatably connected to the left and right sides of the outer side of the positioning shell 202. The threads on the surfaces of the two horizontal threaded rods 204 are opposite in direction. The surfaces of the two horizontal threaded rods 204 are threadedly connected to the inner walls of the two moving blocks 205 respectively. The ends of the two horizontal threaded rods 204 that are far apart from each other are rotatably connected to the sides of the two positioning plates 203 that are close to each other. The ends of the two horizontal threaded rods 204 that are close to each other extend into the interior of the positioning shell 202 and are rotatably connected thereto.

[0031] Furthermore, horizontally arranged guide rods 206 are fixedly connected to both the left and right sides of the positioning shell 202. The two guide rods 206 are arranged parallel above the two horizontal threaded rods 204. The two guide rods 206 are slidably connected to the two moving blocks 205 respectively. The side of the two guide rods 206 away from the positioning shell 202 is fixedly connected to the side of the two positioning plates 203 that are close to each other. Horizontally arranged driven bevel gears 207 are fixedly connected to one end surface of the two horizontal threaded rods 204 inside the positioning shell 202.

[0032] Furthermore, a power bevel gear ring 208 is rotatably connected to the lower part of the positioning shell 202. The bottom of the power bevel gear ring 208 is rotatably connected to the center of the top of the protective cover 2. The left and right sides of the top of the power bevel gear ring 208 are perpendicularly meshed with the bottom of two driven bevel gears 207. A power bevel gear 209 is meshed with the rear side of the top of the power bevel gear ring 208 and is perpendicularly arranged thereto. A second motor 210 is fixedly connected to the rear side of the top of the protective cover 2. The output shaft of the second motor 210 is fixedly connected to the inner wall of the power bevel gear 209.

[0033] Specifically, a positioning shell 202 is fixedly connected to the center of the top of the protective cover 2. Vertically mounted electric telescopic rods 302 are fixedly connected to the bottom of both movable blocks 205. The telescopic ends of the electric telescopic rods 302 extend downwards into the lower part of the protective cover 2, and a U-shaped plate 301 is fixedly connected to their ends. Thus, the vertical lifting and lowering adjustment of the U-shaped plate 301 and the ultraviolet lamp 3 mounted on it is achieved through the telescopic movement of the electric telescopic rods 302. The rods of the two electric telescopic rods 302 penetrate the movable groove 201 at the top of the protective cover 2, and their surfaces are flush with the interior of the movable groove 201. The sliding fit between the walls ensures stable and non-deviation-free lifting. Positioning plates 203 are fixedly connected to the left and right sides of the top of the protective cover 2. Horizontal threaded rods 204 are rotatably connected to the left and right sides of the outer side of the positioning shell 202. The threads of the two horizontal threaded rods 204 are opposite in direction. Both ends of each horizontal threaded rod 204 are threadedly connected to the inner wall of the moving block 205 on the same side, enabling it to drive the moving block 205 to move axially during rotation. The ends of the horizontal threaded rods 204 that are far apart from each other are rotatably connected to the sides of the positioning plates 203 that are close to each other. The ends that are close to each other extend into the interior of the positioning housing 202 and are rotatably connected to the positioning housing 202. Horizontally arranged guide rods 206 are fixedly connected to the left and right sides of the outside of the positioning housing 202. The two guide rods 206 are arranged parallel above the horizontal threaded rods 204. Two moving blocks 205 are slidably connected to their corresponding guide rods 206, serving as limiters and guides. A horizontally arranged driven bevel gear 207 is fixedly connected to one end of each of the two horizontal threaded rods 204 inside the positioning housing 202. A power bevel gear ring 20 is rotatably connected to the lower part of the inside of the positioning housing 202. 8. The bottom of the power bevel gear ring 208 is rotatably connected to the center of the top of the protective cover 2, and can rotate freely around the vertical axis. The left and right sides of the top of the power bevel gear ring 208 are respectively perpendicularly meshed with the bottom of the two driven bevel gears 207. When the power bevel gear ring 208 rotates, it can synchronously drive the two driven bevel gears 207 to rotate. The rear side of the top of the power bevel gear ring 208 is also meshed with a power bevel gear 209 perpendicular to it. The power bevel gear 209 is driven by the second motor 210 fixed on the rear side of the top of the protective cover 2, and its output shaft is fixedly connected to the inner wall of the power bevel gear 209.

[0034] Furthermore, when the placement seat 7, which carries the PCB board to be cured, moves to the lower part of the protective cover 2, different PCB boards have different curing requirements. When it is necessary to adjust the horizontal distance between the two ultraviolet lamps 3 to cover a larger irradiation area, the operator starts the second motor 210 through the controller 17. After starting, the second motor 210 drives the power bevel gear 209 to rotate inside the positioning shell 202. When the power bevel gear 209 rotates with the second motor 210, it drives the power bevel gear ring 208, which is perpendicularly meshed with it, to rotate vertically along the axis of the power bevel gear ring 208 at the center of the top of the protective cover 2. When the power bevel gear ring 208 rotates synchronously with the power bevel gear 209... During rotation, two driven bevel gears 207, which are perpendicularly meshed with the top left and right sides of the power bevel gear ring 208, rotate synchronously with the power bevel gear ring 208. When the two driven bevel gears 207 rotate synchronously, two horizontal threaded rods 204 disposed on the inner walls of the two driven bevel gears 207 rotate synchronously in the horizontal direction. When the two horizontal threaded rods 204 rotate coaxially with the two driven bevel gears 207, two moving blocks 205 disposed on the surfaces of the two horizontal threaded rods 204 rotate with the horizontal threaded rods 204. Since the two moving blocks 205 are slidably connected to the two guide rods 206, and the thread directions on the surfaces of the two horizontal threaded rods 204 are opposite, when the two horizontal threaded rods 207 rotate synchronously, the two moving blocks 205 rotate synchronously in the horizontal direction. 4. When the two driven bevel gears 207 rotate coaxially, the two moving blocks 205 can gradually move closer or further apart along the surfaces of the two horizontal threaded rods 204. When the second motor 210 rotates forward, the two moving blocks 205 move closer together from the left and right sides of the protective cover 2 towards its center along the surfaces of the two horizontal threaded rods 204. At this time, the two moving blocks 205 drive the electric telescopic rod 302 and U-shaped plate 301 at the bottom, causing the two ultraviolet lamps 3 to gradually move closer together, which facilitates the adjustment of the horizontal distance between the two ultraviolet lamps 3. When the second motor 210 rotates in reverse, the two moving blocks 205 move from the center of the protective cover 2 towards its left and right sides along the surfaces of the two horizontal threaded rods 204. At this time, the two... The movable block 205 drives the bottom electric telescopic rod 302 and U-shaped plate 301 to gradually move the two ultraviolet lamps 3 away from each other, making it easier to adjust the horizontal distance between the two ultraviolet lamps 3. By adjusting the horizontal distance between the two ultraviolet lamps 3, the irradiation range of the ultraviolet lamps 3 can be adjusted, thus improving the applicability of the equipment. When it is necessary to adjust the vertical distance between the bottom of the two ultraviolet lamps 3 and the top of the PCB board supported by the placement seat 7, the operator starts the two electric telescopic rods 302 through the controller 17. The two electric telescopic rods 302 move downward, causing the U-shaped plate 301 and ultraviolet lamps 3 to gradually move closer to the top of the PCB board, adapting to the curing requirements of PCB boards of different sizes.

[0035] When using this PCB board to process adhesive curing machine, place the PCB board on the placement seat 7, control the conveyor belt 6 to move and transport the PCB board to the right, and the ultraviolet lamp 3 irradiates and cures the PCB board. When the placement seat 7 gradually moves into the protective cover 2, the adjusting rod can be squeezed due to the obstruction of the fixed plate. The piston slides in the air groove to adjust the air pressure in the fixed suction cup, so that the fixed suction cup adsorbs the PCB board under negative pressure, ensuring the stability of the PCB board transportation and curing process. During operation, when the placement seat 7 carrying the PCB board to be cured moves to the lower part of the protective cover 2, if it is necessary to adjust the horizontal distance between the two ultraviolet lamps 3 to optimize the irradiation coverage according to the PCB board size or adhesive type, the operator can start the second motor 210 through the controller 17. After the second motor 210 starts, it drives the power bevel gear 209 to rotate. The power bevel gear 209 drives the power bevel gear ring 208, which is perpendicularly meshed with it, to rotate around its central vertical axis. Since the power bevel gear ring 208 is perpendicularly meshed with the left and right driven bevel gears 207 at the same time, its rotation will be synchronously transmitted to the two driven bevel gears 207, thereby driving the two horizontal threaded rods 204 fixed coaxially with it to rotate synchronously. Since the thread directions of the two horizontal threaded rods 204 are opposite, and the two moving blocks 205 are respectively engaged with their threads, when the second motor 210 rotates forward, the two moving blocks 205 move from the protective cover 2... The left and right sides move closer to each other towards the center, causing the electric telescopic rods 302, U-shaped plates 301, and UV lamps 3 below them to retract synchronously. When the second motor 210 reverses, the two moving blocks 205 move away from the center to the left and right sides, causing the two UV lamps 3 to unfold. This enables bidirectional adjustment of the horizontal spacing of the UV lamps 3, adapting to the curing needs of different widths or irregularly shaped areas. When it is necessary to adjust the vertical distance between the UV lamps 3 and the PCB board surface, the operator can control the two electric telescopic rods 302 through the controller 17. When the electric telescopic rods 302 extend downwards, they cause the U-shaped plates 301 and the UV lamps 3 on them to gradually approach the PCB board surface, increasing the illuminance intensity. When they retract upwards, they increase the distance. The vertical adjustment function effectively solves the problem of uneven curing caused by differences in PCB thickness or component height, improving the equipment's adaptability to a variety of products.

[0036] In summary, through the coordinated action of the second motor 210, the power bevel gear 209, the power bevel gear ring 208, the driven bevel gear 207, the horizontal threaded rod 204, the guide rod 206, the moving block 205, the electric telescopic rod 302, and the U-shaped plate 301, the flexible adjustment of the horizontal spacing and vertical height of the ultraviolet lamp 3 is achieved, significantly enhancing the process adaptability and automation level of the equipment and meeting the diverse needs of different PCB boards for adhesive curing.
