Description

Technical Field

[0001] The utility model relates to the technical field of UV curing ovens, in particular to a UV curing oven for processing circuit boards. Background Art

[0002] The circuit board is a printed circuit board, also known as a printed circuit board. The main advantage of using a circuit board is that it can reduce errors during wiring and assembly, which is conducive to improving the level of automated production. During the processing of existing circuit boards, it is usually necessary to spray the surface of the circuit board, and the sprayed circuit board needs to be placed in a UV curing oven to cure the surface paint.

[0003] For example, the Chinese utility model patent with patent publication number CN217369103U includes a curing furnace main body and a storage plate. The inner walls on both sides of the curing furnace main body are installed with storage plates, a tray is placed on the top of the storage plate, and a focusing plate is installed on the top and bottom of the tray. The tops of the two groups of storage plates and trays are penetrated by evenly distributed light-transmitting holes, the top of the upper focusing plate is installed with a support rod, and the tops of the upper focusing plate and tray are provided with symmetrically arranged slide grooves, the interiors of the two groups of the slide grooves are slidably installed with slide rods, and the tops of the two groups of slide rods are installed with splints.

[0004] This patent can be installed with a storage plate, a support rod, a clamping plate and a light-transmitting hole, and the circuit board can be placed on the top of the support rod, and the clamping plate and the circuit board can be fixed with screws. During the curing process, UV light will be irradiated on the outer surface of the circuit board through the light-transmitting hole, which can increase the contact area between the light source and the circuit board to a certain extent. However, when fixing the circuit board, it is necessary to first place the circuit board on the top of the support rod, and then move the sliding rod to make the clamping plate close to the circuit board, and then twist the screw into the inside of the threaded hole. However, a large number of circuit boards are fixed at one time, and it takes a lot of time to repeat the above work. The overall process is relatively cumbersome, which leads to insufficient overall curing efficiency. In view of this, we propose a UV curing furnace for circuit board processing. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a UV curing furnace for circuit board processing, which can solve the problem of complicated procedures when fixing multiple circuit boards.

The outer surface of the mounting sleeve is rotatably connected to a push rod, and the other end of the push rod is rotatably connected to the outer surface of the support rod.

[0008] Preferably, the adjacent side surfaces of the two clamping plates are respectively fixedly connected with rubber plates.

[0009] Preferably, the interior of the storage plate is configured to be hollow, and the bottom wall of the mounting groove is provided with two second sliding grooves extending into the interior of the storage plate, and the inner walls of the two second sliding grooves are respectively slidably connected to sliding rods.

[0010] Preferably, the upper ends of the two sliding rods are fixedly connected to the limit plate, and the lower ends of the two sliding rods are respectively fixedly connected to the displacement plate.

[0011] Preferably, the front surface of the storage plate is rotatably connected to a knob, the rear surface of the knob is fixedly connected to a rotating rod, and the rear end of the rotating rod rotates and penetrates into the interior of the storage plate.

[0012] Preferably, a first bevel gear is sleeved on the outer surface of the rotating rod, and a second bevel gear is meshedly connected to the outer surface of the first bevel gear.

[0013] Preferably, a triple bidirectional threaded rod is fixedly connected to the right side surface of the second bevel gear, the right end of the triple bidirectional threaded rod is rotatably connected to the inner wall of the storage plate, and the threaded sleeve of the displacement plate is arranged on the outer surface of the triple bidirectional threaded rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The UV curing furnace for processing circuit boards, when placing the circuit board, by manipulating the installation sleeve to descend, the installation sleeve descends and cooperates with the installation assembly to make the two support rods move in opposite directions, and then the two support rods are used to drive the two displacement blocks to move, and the two displacement blocks will compress the two springs synchronously when moving, and the two displacement blocks will be limited by the two limit rods when moving, and at the same time, when the support rods move, they will synchronously drive the two clamps away from each other, and then the circuit board is placed on the upper surface of the storage column, at this time, the installation sleeve is slowly manipulated to move upward, and then the elastic force of the spring pushes the displacement block to move, so that the support rod is used to drive the clamp to reset, and then the circuit board is clamped and fixed. Through the above structure, when clamping and fixing the circuit board, it is only necessary to manipulate the installation sleeve to descend, and then place the circuit board and release the control of the installation sleeve. The overall process is simpler and more efficient, making it faster to fix and clamp a large number of circuit boards.

[0016] (2) The UV curing furnace for processing circuit boards, after all the circuit boards are fixed and clamped, by turning the knob, the knob synchronously drives the first bevel gear to rotate using the rotating rod, and after the first bevel gear rotates, it synchronously drives the second bevel gear to rotate, and the second bevel gear rotates and then drives the triple bidirectional threaded rod to rotate, and the triple bidirectional threaded rod drives the limit plate to move using the cooperation of the displacement plate and the sliding rod, and the limit plate contacts the support rod after movement, thereby completing the limitation of the support rod. Through the above structure, not only can all the circuit boards be strengthened and fixed more conveniently after the circuit boards are initially fixed, avoiding the spring contraction caused by factors such as vibration caused by picking up, thereby causing the fixation of the circuit boards to be loose, but also the rubber plate can be used to avoid damage to the circuit boards during clamping.

[0026] See also Figure 1-6The utility model provides a technical solution: a UV curing furnace for processing circuit boards, comprising a main body 1, a placement slot 2 is opened on the front side surface of the main body 1, and the left and right inner walls of the placement slot 2 are respectively fixedly connected with a support plate 3, and the upper surface of the support plate 3 is provided with a placement plate 4, and the upper surface of the placement plate 4 is opened with a mounting slot 5. The bottom wall of the mounting slot 5 is opened with two sliding slots 6, the inner walls of the two sliding slots 6 are respectively fixedly connected with a limit rod 7, and the outer surfaces of the two limit rods 7 are respectively slidably sleeved with a displacement block 8, and the opposite side surfaces of the two displacement blocks 8 are respectively fixedly connected with a spring 15, and the opposite ends of the two springs 15 are respectively fixedly connected to the inner walls of the two sliding slots 6, the upper surface of the displacement block 8 is fixedly connected with a support rod 9, and the upper ends of the two support rods 9 are respectively fixedly connected with a clamping plate 10, and the bottom wall of the mounting slot 5 is fixedly connected with a placement column 11, and the outer surface of the placement column 11 is slidably sleeved with a mounting sleeve 12, and a mounting assembly is provided on the mounting sleeve 12. When the load is lifted, the two support rods 9 are lowered, and the two support rods 9 are used to drive the two displacement blocks 8 to move. When the two displacement blocks 8 move, the two springs 15 are compressed synchronously, and the two displacement blocks 8 are limited by the two limit rods 7 when they move. At the same time, when the support rods 9 move, the two clamping plates 10 are synchronously driven to move away from each other, and then the circuit board is placed on the upper surface of the storage column 11. At this time, the installation sleeve 12 is slowly controlled to move upward, and the elastic force of the spring 15 pushes the displacement block 8 to move, thereby using the support rod 9 to drive the clamping plate 10 to reset, and then complete the clamping and fixing of the circuit board. Through the above structure, when clamping and fixing the circuit board, it is only necessary to control the installation sleeve 12 to descend, and then place the circuit board and release the control of the installation sleeve 12. The overall process is simpler and more efficient, making it faster to fix and clamp large quantities of circuit boards.

[0027] Furthermore, the mounting assembly includes a pressing plate 13, which is fixedly connected to the outer surface of the mounting sleeve 12. The outer surface of the mounting sleeve 12 is rotatably connected to a push rod 14. The other end of the push rod 14 is rotatably connected to the outer surface of the support rod 9. The two adjacent side surfaces of the two splints 10 are respectively fixedly connected to a rubber plate 16. The interior of the storage plate 4 is set to be hollow. The bottom wall of the mounting groove 5 is provided with two second sliding grooves 17 extending into the interior of the storage plate 4. The inner walls of the two second sliding grooves 17 are respectively slidably connected to sliding rods 18. The upper ends of the two sliding rods 18 are fixedly connected to the limiting plate 19. The two sliding rods 18 The lower ends of the plates 20 are fixedly connected, the front surface of the storage plate 4 is rotatably connected to a knob 21, the rear surface of the knob 21 is fixedly connected to a rotating rod 22, the rear end of the rotating rod 22 rotates and penetrates into the interior of the storage plate 4, the outer surface of the rotating rod 22 is sleeved with a first bevel gear 23, the outer surface of the first bevel gear 23 is meshed with a second bevel gear 24, the right side surface of the second bevel gear 24 is fixedly connected to a triple bidirectional threaded rod 25, the right end of the triple bidirectional threaded rod 25 is rotatably connected to the inner wall of the storage plate 4, the thread of the displacement plate 20 is sleeved on the outer surface of the triple bidirectional threaded rod 25 The triple bidirectional threaded rod 25 described in the article is a fixed connection component of three bidirectional threaded rods, and the two sets of similar threads are set in opposite directions. At the same time, the displacement plates 20 are respectively sleeved on the outer surfaces of the opposite threads, and the installation sleeve 12 is synchronously driven to move by the pressing plate 13. When the installation sleeve 12 moves, it will synchronously use the push rod 14 to push the two support rods 9 to move, thereby causing the two clamping plates 10 to gradually open. After all the circuit boards are fixed and clamped, by turning the knob 21, the knob 21 synchronously uses the rotating rod 22 to drive the first bevel gear 23 to rotate. After the first bevel gear 23 rotates, it synchronously drives the second bevel gear 2 4 rotates, the second bevel gear 24 rotates and then drives the triple bidirectional threaded rod 25 to rotate, and the triple bidirectional threaded rod 25 uses the cooperation of the displacement plate 20 and the sliding rod 18 to drive the limit plate 19 to move. After the limit plate 19 moves, it contacts the support rod 9, thereby completing the limit of the support rod 9. Through the above structure, not only can all circuit boards be more conveniently fixed at the same time after the circuit board is initially fixed, but also the spring 15 can be prevented from shrinking due to factors such as vibration caused by taking, thereby loosening the fixation of the circuit board. At the same time, the rubber plate 16 can be used to prevent the circuit board from being damaged during clamping.

[0028] Working principle: When placing the circuit board, the installation sleeve 12 is manipulated to descend, and the installation sleeve 12 descends and cooperates with the installation assembly to make the two support rods 9 move in opposite directions, and then the two support rods 9 are used to drive the two displacement blocks 8 to move. When the two displacement blocks 8 move, the two springs 15 are synchronously compressed, and the two displacement blocks 8 are limited by the two limit rods 7 when they move. At the same time, when the support rods 9 move, the two clamps 10 are synchronously driven away from each other, and then the circuit board is placed on the upper surface of the storage column 11. At this time, the installation sleeve 12 is slowly manipulated to move upward, and then the elastic force of the spring 15 pushes the displacement block 8 to move, so that the support rods 9 are used to drive the clamp 10 to reset, thereby completing the circuit board. The board is clamped and fixed, and the installation sleeve 12 is synchronously driven to move by pressing the plate 13. When the installation sleeve 12 moves, it will synchronously use the push rod 14 to push the two support rods 9 to move, so that the two clamping plates 10 are gradually opened. After all the circuit boards are fixed and clamped, by turning the knob 21, the knob 21 synchronously uses the rotating rod 22 to drive the first bevel gear 23 to rotate. After the first bevel gear 23 rotates, it synchronously drives the second bevel gear 24 to rotate. The rotation of the second bevel gear 24 drives the triple bidirectional threaded rod 25 to rotate. The triple bidirectional threaded rod 25 uses the cooperation of the displacement plate 20 and the sliding rod 18 to drive the limit plate 19 to move. After the limit plate 19 moves, it contacts the support rod 9, thereby completing the limitation of the support rod 9.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
