Description

Technical Field

[0001] This utility model relates to the field of PCB printing equipment technology, and in particular to a printing press printing frame. Background Technology

[0002] PCB is the abbreviation for Printed Circuit Board. Generally, a printed circuit refers to a conductive pattern, consisting of printed lines, printed components, or a combination of both, fabricated on an insulating material according to a predetermined design. The conductive pattern on the insulating substrate that provides electrical connections between components is called a printed line. Thus, the finished board containing printed circuits or printed lines is called a printed circuit board, also known as a printed board or printed circuit board. The PCB printing described in this application, also known as circuit board printing, is a rapidly developing new industry, and the rapid development of screen printing has injected vitality into this industry, bringing significant changes to the electronics industry. Current screen printing technology is fully capable of adapting to high-density PCB production.

[0003] In the prior art, such as Chinese Patent No. CN220075905U, a mounting frame and an adjustment mechanism are included. The mounting frame has a mounting plate on its lower interior side, and guide grooves on its upper ends. Support columns are slidably connected inside the guide grooves, and the upper ends of the support columns are fixedly connected to the lower end of the mounting box. A mounting groove is provided in the middle of the upper part of the mounting plate. Connecting plates are provided on the upper interior side of the mounting frame, and placement plates are provided between the opposite inner surfaces of the connecting plates. Fixing clips are provided on the upper ends of the placement plates, and ventilation openings are evenly distributed on the upper ends of the placement plates. The adjustment mechanism is located inside the mounting plate, and its upper end is fixedly connected to the lower end of the mounting box. This printing press's printing frame can drive a fan to reciprocate, increasing the fan's blowing area and further improving the drying efficiency of the printed products, replacing the traditional method of allowing the printed products to air dry naturally, resulting in relatively lower costs.

[0004] While the above solution has the advantages mentioned above, its disadvantages are that it lacks the effect of automatic printing when the printing press is working, and manual operation of the printing screen is still required. This will increase the workload of the staff and reduce work efficiency. At the same time, when changing printed products, manual replacement is required, which can easily cause injury to the staff and increase the risk factor. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the printing machine lacks automatic printing effect during operation. The printing process requires manual use of the printing screen, which increases the workload and reduces the printing production efficiency.

[0015] Two track blocks are installed at the bottom of the top plate, and the long rod passes through the two track blocks;

[0016] The long rod has a gear opening on its surface.

[0017] The technical effect of adopting the above-mentioned further solution is that: installing the track block limits the track of the long rod, preventing the long rod from deviating from a straight line.

[0018] In a preferred embodiment, the lifting component further includes:

[0019] A fixing strip is installed at the bottom of the top plate;

[0020] Gear 1 is rotatably mounted on one side of the fixing strip;

[0021] Wherein, the first gear meshes with the gear opening on the surface of the long rod;

[0022] A T-shaped fixing bracket is installed at the bottom of the top plate;

[0023] Rotating shaft one is embedded in the T-shaped fixing frame. One side of rotating shaft one is fixedly connected to gear one, and gear two is installed on the other side of rotating shaft one.

[0024] The second gear meshes with the toothed column.

[0025] The technical effect of adopting the above-mentioned further solution is that the printing plate moves in the vertical direction through the linkage of the first gear, the second gear and the tooth column.

[0030] The technical effect of adopting the above-mentioned further solution is that the first bevel gear rotates under the operation of the lifting component.

[0031] In a preferred embodiment, the pusher further includes:

[0032] A support column is installed on the top of the base, and a second bevel gear is installed on the top of the support column, which meshes with the first bevel gear;

[0033] Support column two is installed on the top of the base. The top of support column two is equipped with the guide rail. The guide rail is embedded with a rack. The push block is installed on one side of the rack.

[0034] The rack meshes with the second bevel gear.

[0035] The technical effect of adopting the above-mentioned further solution is that the rotation of the first bevel gear drives the rack forward, and then the push block pushes out the PCB.

[0036] In a preferred embodiment, a plurality of support columns are mounted on the top of the base, and the tops of the plurality of support columns are connected to the bottom of the top plate.

[0037] The technical effect of adopting the above-mentioned further solution is that the top plate is supported by the four pillars, providing installation space for the lifting component and the pushing component.

[0039] The technical effect of adopting the above-mentioned further solution is that the printing screen is supported by multiple pillars to the same height as the push block, so that the push block can be directly pushed out of the PCB.

[0040] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0041] 1. This utility model involves placing the PCB on a printing screen. With the operation of a telescopic rod, the telescopic end of the rod extends, driving a long rod forward. This forward extension drives gear one to rotate via a gear slot on the long rod. Since gear one and gear two are connected to opposite ends of the rotating shaft, gear two rotates synchronously with gear one. At this time, gear two drives a gear column to move vertically downwards, pressing the printed circuit board completely onto the PCB surface to begin printing. This solution enables mechanized and automated PCB printing, reducing the complexity of manual printing.

[0042] 2. In this invention, when the telescopic rod retracts, it simultaneously resets the long rod. Gear 1 drives Gear 3 to rotate, and Gear 3 drives Gear 4 to rotate. The two ends of the rotating shaft are connected to Gear 4 and the first bevel gear, causing the first bevel gear to drive the second bevel gear to rotate. The first bevel gear then drives the rack to move linearly horizontally. At this time, because the long rod resets, the printed circuit board (PCB) is lifted, and the rack drives the push block to push the PCB out. This design allows the PCB to be automatically pushed out as it is lifted after printing, avoiding potential safety hazards from manual handling. Attached Figure Description

[0050] 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.

[0051] Example 1:

[0052] Please see Figures 1-5 This embodiment provides a printing press screen frame for automatic printing, the specific idea of ​​which is as follows:

[0053] The printing press includes a top plate 1 and a base 4. A toothed column 101 is mounted on the top of the top plate 1, extending through the top of the top plate 1. A printing plate 102 is mounted on the bottom of the toothed column 101. The printing frame of the printing press also includes:

[0054] Telescopic rod 103 is installed at the bottom of top plate 1.

[0055] The lifting component, located at the bottom of the top plate 1, can move the printing plate 102 vertically under the drive of the telescopic rod 103.

[0056] To ensure that the toothed column 101 does not rotate during the operation of the lifting component, its shape is rectangular.

[0057] The lifting components include: a long rod 104, two track blocks 110, a fixing bar 105, a gear 106, a T-shaped fixing frame 107, and a rotating shaft 108.

[0058] The long rod 104 is fixedly installed on the telescopic end of the telescopic rod 103 by welding, and a limit block is installed on the other end of the long rod 104.

[0059] It should be noted that the telescopic pole 103 is an electric telescopic pole, and this device is existing technology, so it will not be described in detail here.

[0060] The two track blocks 110 are fixed to the bottom of the top plate 1 by bolts, and the long rod 104 passes through the two track blocks 110.

[0061] In order to ensure that the long rod 104 can drive the gear 106 to rotate, a gear opening is provided on the surface of the long rod 104.

[0062] In addition, the fixing strip 105 that needs to be installed is fixedly installed at the bottom of the top plate 1.

[0063] The gear 106 is rotatably connected to one side of the fixing bar 105 via a rotating shaft.

[0064] Among them, the gear 106 and the gear mouth on the surface of the long rod 104 mesh.

[0065] In addition, the T-shaped bracket 107 in this design is bolted to the bottom of the top plate 1.

[0066] The rotating shaft 108 is embedded in the T-shaped fixing bracket 107. One side of the rotating shaft 108 is fixedly connected to the gear 106, and the other side of the rotating shaft 108 is equipped with the gear 2 109.

[0067] Among them, gear 109 meshes with gear post 101.

[0068] In this embodiment, the PCB to be printed is placed on the printing screen 301. Driven by the telescopic rod 103, the telescopic end of the telescopic rod 103 extends and drives the long rod 104 to run, so that the gear mouth on its surface drives the gear 106 to rotate. Since the gear 106 and the gear 2 109 are respectively connected to the two ends of the rotating shaft 108, the gear 2 109 starts to rotate and drives the tooth column 101 to move in the vertical direction.

[0069] Example 2:

[0070] Please see Figures 1-5 Based on Example 1, this example provides a printing press screen frame that can automatically eject PCBs. The specific idea is as follows:

[0075] The rotating shaft 202 is installed on one side of the fixing strip 105 and passes through the fixing strip 105.

[0076] It should be noted that one end of the rotating shaft 202 is rotatably mounted with gear 4 201, which is meshed with gear 3 2, and the other end of the rotating shaft 202 is rotatably mounted with first bevel gear 203.

[0077] The auxiliary support column 207 is installed on the top of the base 4 by hexagonal bolts. The top of the support column 207 is equipped with a second bevel gear 204, which meshes with the first bevel gear 203.

[0078] In addition, the second support column 208, which also plays an auxiliary role, is installed on the top of the base 4 by hexagonal bolts. The top of the second support column 208 is equipped with a guide rail 206, and a rack 205 is embedded in the guide rail 206. A push block 209 is installed on one side of the rack 205.

[0079] Among them, the rack 205 meshes with the second bevel gear 204.

[0080] It should be noted that the surface of the guide rail 206 has small holes, through which machine oil can be added to ensure that the rack 205 slides more smoothly in the guide rail 206 while reducing wear. Therefore, the shape of the small holes includes, but is not limited to, rectangles, circles or polygons. This application uses circles.

[0081] In addition, multiple support columns 401 are installed on the top of the base 4, and the top of the multiple support columns 401 is connected to the bottom of the top plate 1. At the same time, multiple support columns 3 are installed on the top of the base 4, and a printing screen 301 is installed on the top of the multiple support columns 3. The printing screen 301 is at the same height as the push block 209.

[0082] Among them, multiple support pillars 401 and multiple support pillars 3 all play a supporting role, so their shapes include but are not limited to rectangles, circles or polygons. This application uses cylinders.

[0083] In this embodiment, when the telescopic end of the telescopic rod 103 is reset, it will drive the long rod 104 to retract. At this time, the printed circuit board 102 is lifted, the gear one 106 drives the gear three 2 to rotate, the gear three 2 drives the gear four 201 to rotate, and the two ends of the rotating shaft two 202 are connected to the gear four 201 and the first bevel gear 203, so that the first bevel gear 203 drives the second bevel gear 204 to rotate, the first bevel gear 203 drives the rack 205 to run in the horizontal direction, and the rack 205 drives the push block 209 to push out of the PCB.

[0084] In addition, it should be noted that in the previous embodiments, the printing press screen frame may also include a battery pack, which provides power to the electronic devices involved in the printing press screen frame, such as the telescopic rod 103. The circuit is connected using existing conventional connection methods, which will not be described in detail here.

[0085] Working principle:

[0086] When printing is required on the PCB, the PCB is placed on the printing screen 301. At this time, the telescopic rod 103 is activated. The telescopic end of the telescopic rod 103 drives the long rod 104 to advance. At this time, the gear port on the long rod 104 drives the gear 106 to rotate. The gear 106 and the gear 2 109 are connected through the rotating shaft 108. The gear 2 109 rotates synchronously with the gear 106. The gear 2 109 drives the toothed column 101 to move downward in the vertical direction, so that the printing board 102 is completely pressed onto the surface of the PCB to start printing.

[0087] After printing is completed, the telescopic end of the telescopic rod 103 drives the long rod 104 to retract. At this time, gear one 106 drives gear three 2 to rotate, gear three 2 drives gear four 201 to rotate. Gear four 201 and the first bevel gear 203 are connected through the rotating shaft two 202. Therefore, the first bevel gear 203 and gear four 201 rotate synchronously. The first bevel gear 203 drives the second bevel gear 204 to rotate. The first bevel gear 203 drives the rack 205 to move linearly in the horizontal direction. When the printed circuit board 102 is lifted, the rack 205 drives the push block 209 to push the PCB to the side. At this time, the printed PCB can be taken away.
