Description

Technical Field

[0001] The invention relates to the technical field of developing, and in particular to a high-precision developing device. Background Art

[0002] After laser exposure, the IC substrate needs to enter the developing line to complete the image welding and imaging. Development is a process of making the image appear in the printing, photocopying, copying, and printing industries. Development includes positive development and reverse development. In positive development, the polarity of the charge carried by the developing toner is opposite to the charge polarity of the electrostatic latent image on the surface of the photosensitive drum. In reverse development, the charge polarity of the photosensitive drum and the toner are the same.

[0003] The prior art patent announcement number is CN221668173U, which is a circuit developing device. The above patent lifts the pull rod on the top surface of the connecting frame to move the pressing plate at one end of the pull rod, and places the circuit board to be processed on the top surface of the placement plate. The pull rod is released, and the pressure plate abuts against the circuit board on the top surface of the placement plate through the action of the reset spring, so that the circuit board can be pressed and positioned to prevent the circuit board from tilting and deviating during processing, thereby facilitating improving the stability of the circuit board during processing. The water pump is turned on, and the water pump transports the developing solution in the liquid storage tank to the spray pipe through the liquid delivery pipe, and then the developing solution is sprayed out through the spray head, so that the circuit board can be developed.

[0004] It can be seen from the above patent content that the positioning and pressing of the circuit board is mainly completed on the placement board. When the circuit board is fixed, one side of it faces upward, facing the spray pipe, and the other side is in contact with the placement board. During the actual spraying operation, the spray pipe can only spray the upward side of the circuit board. The other side cannot contact the liquid medicine due to contact with the placement board. This leads to the need to open the developing equipment separately later, release the fixation of the circuit board, and then turn the circuit board over. The entire process is time-consuming and labor-intensive in actual operation, and the efficiency is relatively low. Summary of the invention

When the circuit board is fixed, one side of the circuit board faces upward, facing the spray pipe, and the other side is in contact with the placement board. During the actual spraying operation, the spray pipe can only spray the upward side of the circuit board, and the other side cannot contact the liquid medicine due to contact with the placement board.

[0033] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0034] Reference Figure 1-7 As shown, a high-precision developing device comprises a developing device body 1 with an opening on one side, a closed door plate 2 hinged on the opening surface of the developing device body 1, and a spraying mechanism built into the developing device body 1;

[0035] The spraying mechanism includes a spray pipe 3 transversely fixed to the inner side of the developing device body 1, a plurality of spray heads 4 equidistantly fixedly connected to the bottom surface of the spray pipe 3, and a water suction pump 5 installed on a side wall of the developing device body 1, the suction end of the water suction pump 5 penetrates into the bottom of the inner cavity of the developing device body 1, the output end of the water suction pump 5 is fixedly connected to a water supply pipe 6, the end of the water supply pipe 6 penetrates into the developing device body 1 and is fixedly connected to the spray pipe 3;

[0036] The water suction pump 5 is turned on, and the absorption end of the water suction pump 5 continuously sucks the developer liquid stored in the bottom of the inner cavity of the developing device body 1, so that the developer liquid is injected into the spray pipe 3 through the water supply pipe 6 and sprayed out from the nozzle 4 to facilitate the development and processing of the circuit board.

[0037] Further, refer to Figure 3-5 As shown, it is worth noting that it also includes a flip-type fixed plate mechanism for spraying both sides of the circuit board, and the flip-type fixed plate mechanism is located directly below the spray pipe 3;

[0038] The flip-type fixed plate mechanism includes a slide rail 11 distributed laterally, four sets of movable corner clamping parts distributed in a rectangular shape outside the opening of the slide rail 11, and a supply and rotation part arranged outside the developing device body 1;

[0039] The supply and rotation part includes a motor 32 mounted on the outer side wall of the developing device body 1, and the output shaft of the motor 32 rotates to penetrate into the developing device body 1 and is fixedly connected to the middle part of the slide rail 11;

[0040] By setting the supply and rotation part, after the spraying mechanism completes the liquid medicine treatment on one side of the circuit board, it is only necessary to turn on the motor 32 and rotate the slide rail 11 180 degrees, and the movable corner clamping part can synchronously flip the circuit board, thereby realizing the turning over of the circuit board in a short time, which is beneficial to the liquid medicine treatment on both sides of the circuit board.

[0041] Further, refer to Figure 4 and Figure 5 As shown, it is worth noting that the movable corner clamping portion is mainly composed of a right-angled corner piece 7 and two limiting slide plates 16, and the two limiting slide plates 16 elastically slide on the two end surfaces of the corner piece 7 respectively;

[0042] By setting the movable corner clamping part, the corner of the circuit board is clamped into the inner side of the corner piece 7, and the limiting slide plates 16 on the two end surfaces of the corner piece 7 can respectively contact the two end surfaces of the circuit board. In this way, four sets of movable corner clamping parts cooperate to position and support the four corners of the circuit board, thereby achieving a firm positioning effect on the circuit board, so that the circuit board cannot be tilted or offset during processing.

[0043] Further, refer to Figure 4 and Figure 5 As shown, it is worth noting that the flip positioning mechanism also includes a shaping adjustment portion for enhancing the applicability of the movable corner clamping portion;

[0044] The shaping and adjusting part is mainly composed of coordination groups 1 and 2. The coordination group 1 is located inside the slide rail 11, and the coordination group 2 is divided into two groups. The two coordination groups 2 are respectively located between the two corner pieces 7 on the left and right sides.

[0045] By setting the shaping adjustment part, the positions of the four sets of movable corner clamping parts can be flexibly adjusted, so that the four sets of movable corner clamping parts are suitable for positioning circuit boards of different sizes and models, thereby enhancing the use range and practicality of the device.

[0046] Further, refer to Figure 4 and Figure 5 As shown, it is worth noting that the coordination group 1 includes a bidirectional screw 12 that rotates horizontally between the inner walls of the two sides of the slide rail 11 and two slide seats 13 that are symmetrically threadedly sleeved on the rod body of the bidirectional screw 12, and the two slide seats 13 are respectively fixedly connected to the two corner pieces 7 located at the rear end;

[0047] The second coordination group includes a telescopic rod 8 distributed horizontally and support seats 9 fixedly sleeved at both ends of the telescopic rod 8. The two support seats 9 are respectively fixed to the two corner pieces 7 located in the side area, and a stud 10 is threadedly penetrated on the sleeve of the telescopic rod 8.

[0048] Push the corner piece 7 at the front end, that is, the telescopic rod 8 is contracted and adjusted, thereby quickly adjusting the distance between the two corner pieces 7 in the front and rear areas, and then turn the knob stud 10 so that the stud 10 is pressed against the sliding rod of the telescopic rod 8, and the distance between the two corner pieces 7 in the front and rear areas can be effectively locked;

[0049] When the bidirectional screw 12 rotates, the two slide seats 13 can slide toward each other under the thread structure of the bidirectional screw 12, thereby quickly adjusting the distance between the corner pieces 7 on both sides;

[0050] Thus, by coordinating the cooperation between groups one and two, the four groups of corner wrapping parts 7 can be easily and accurately installed on the four corners of circuit boards of different sizes and models, which greatly expands its scope of application and greatly improves its practicality.

[0051] Further, refer to Figure 5 As shown, it is worth noting that a positioning support sheet 14 is vertically fixed on the inner wall of one side of the slide rail 11, and a control main rod 15 is rotatably penetrated in the inner wall of the positioning support sheet 14, and one end of the control main rod 15 is connected to the bidirectional screw 12 through a bevel gear transmission;

[0052] The knob controls the main rod 15 , and the control of the main rod 15 can drive the bidirectional screw 12 through the bevel gear, thereby providing rotational force for the bidirectional screw 12 .

[0053] In the above embodiment, although the positions of the four sets of movable corner clamping parts can be flexibly adjusted through the setting of the shaping adjustment part, so that the four sets of movable corner clamping parts are suitable for positioning circuit boards of different sizes and models, and the circuit board can be turned over in a short time through the setting of the supply and rotation part, which is beneficial to the liquid treatment of both sides of the circuit board, when the movable corner clamping part composed of the corner wrapping piece 7 and the two limiting slide plates 16 is clamped at the corner of the circuit board, the limiting slide plate 16 will form a physical shielding of the circuit board surface, so that the developer liquid cannot smoothly and comprehensively cover the area of ​​the circuit board blocked by the limiting slide plate 16 after being sprayed from the nozzle 4, which reduces the uniformity of the liquid treatment of the circuit board to a certain extent;

[0054] For this purpose, refer to Figure 3-5 As shown, it is worth noting that it also includes a synergistic mechanism for improving the circuit board liquid treatment effect, and the synergistic mechanism is divided into two groups, and the two groups of synergistic mechanisms are symmetrically distributed on both sides of the developing device body 1;

[0055] The synergistic mechanism includes two C-shaped symmetrically distributed abutment seats 20 and a push-pull portion arranged between the two abutment seats 20. The two abutment seats 20 contact the two corner pieces 7 located in the side area respectively, and a pressure sensor is embedded in one end of the abutment seat 20 contacting the corner piece 7. The opening of the abutment seat 20 corresponds to the limiting slide 16 at the upper end of the corner piece 7. A bar magnet 19 is installed on the side wall of the limiting slide 16. An electromagnet 21 corresponding to the bar magnet 19 is installed on the innermost inner wall of the abutment seat 20. The pressure sensor is electrically connected to the electromagnet 21.

[0056] A sliding slot is transversely provided on the limiting slide plate 16, a fixed slide 17 fixedly connected to the top of the corner wrapping member 7 is slidably arranged in the sliding slot, and a compression spring 18 is fixed between the fixed slide 17 and the inner wall of one side of the sliding slot;

[0057] By setting the synergistic mechanism, after the resin plate is clamped between the four sets of movable corner clamping parts, the push-pull part is used to slide the abutment seat 20 toward the corner piece 7 until the pressure sensor at the end of the abutment seat 20 abuts against the corner piece 7. The pressure sensor senses the pressure and turns on the electromagnet 21, so that the electromagnet 21 forms a magnetic attraction on the bar magnet 19, which acts to limit the slide plate 16 from quickly sliding into the inner side of the abutment seat 20 and no longer covering the top surface of the resin plate. In this way, the covering of the side of the resin plate facing the spray pipe 3 is reduced, and the liquid treatment effect on the surface is significantly improved.

[0058] During the movement of the limiting slide 16, the fixed slide 17 remains fixed and cooperates with the sliding of the limiting slide 16 to continuously compress the compression spring 18 to deform. In this way, the elastic force of the compression spring 18 is utilized. When the push-pull portion is utilized to move the abutment seat 20 away from the corner piece 7 so that the pressure sensor is no longer subjected to the extrusion pressure, the electromagnet 21 is turned off, so that the magnetic attraction between it and the bar magnet 19 disappears. The limiting slide 16 is then quickly reset to slide to the top surface of the resin board under the elastic force of the compression spring 18, thereby limiting the corners of the resin board to prevent the resin board from falling when the resin board is flipped over.

[0059] Further, refer to Figure 3 As shown, it is worth noting that the push-pull portion includes a support frame 22 vertically fixed above the abutment seat 20 and a connecting frame 23 fixed between the two support frames 22, wherein a push-pull screw 30 is rotatably connected to one of the support frames 22, and the end of the push-pull screw 30 is threadedly penetrated through the developing device body 1, and a guide slide 31 is vertically fixed to the other support frame 22, and the end of the guide slide 31 slides through the developing device body 1;

[0060] The knob pushes and pulls the screw 30 , and the push-and-pull screw 30 can continuously penetrate into the developing device body 1 in the threaded structure and push the connecting frame 23 and the supporting frame 22 as a whole, so that the supporting frame 22 slides toward the corner piece 7 .

[0061] Further, refer to Figure 3 and Figure 7 As shown, it is worth noting that the synergistic mechanism also includes two connecting seats 24 symmetrically fixed on the side wall of the developing device body 1, a rotating rod 25 rotating between the two connecting seats 24, and a winding roller 26 tightly sleeved on the rod body of the rotating rod 25, the roller body of the winding roller 26 is wound with a coating belt 27, the end of the coating belt 27 penetrates into the developing device body 1 and is fixedly connected to the connecting frame 23, and the liquid outlet end of the nozzle 4 abuts against the top surface of the coating belt 27;

[0062] By setting the covering belt 27, when the push-pull part is used to drive the abutting seat 20 to slide toward the corner piece 7, the connecting frame 23 will synchronously produce an action to pull the covering belt 27, and this pulling force will be transmitted to the rotating rod 25 and the winding roller 26, so that the whole is forced to rotate. As the rotation proceeds, the covering belt 27 on the winding roller 26 is gradually released and slowly covers the bottom surface of the spray pipe 3. When the abutting seat 20 finally slides to and abuts the corner piece 7, the covering belts 27 on both sides of the bottom surface of the spray pipe 3 cooperate with each other, so that only the nozzles 4 corresponding to the resin plate are exposed on the spray pipe 3, and the other nozzles 4 are tightly covered by the covering belt 27.

[0063] Therefore, the exposure of the nozzle 4 of the spray pipe 3 can be quickly adjusted according to the size of the resin plate to be processed, the range of the spraying operation can be accurately controlled, and the excess liquid can be prevented from being sprayed to unnecessary areas, thereby greatly improving the development quality of the resin plate.

[0064] Further, refer to Figure 7 As shown, it is worth noting that the shaft of the rotating rod 25 is also sleeved with a torsion spring 29, and the torsion spring 29 is outer-mounted with a fixing sleeve 28 fixed vertically to the connecting seat 24, and the two ends of the torsion spring 29 are respectively fixedly connected to the shaft of the rotating rod 25 and the inner wall of the fixing sleeve 28;

[0065] As shown above, when the connecting frame 23 pulls the covering belt 27 and acts to rotate the rotating rod 25 and the winding roller 26 as a whole, the rotating rod 25 can still synchronously twist the torsion spring 29 to deform the torsion spring 29. In this way, the elastic force of the torsion spring 29 is utilized, and when the push-pull part is used to act on the connecting frame 23 to slide in the opposite direction to reduce the pulling on the covering belt 27, the rotating rod 25 can carry the winding roller 26 in the opposite direction under the elastic force of the torsion spring 29 to rewind the covering belt 27, thereby reasonably organizing the covering belt 27 for secondary use.
