Description

Technical Field

[0001] This utility model belongs to the field of insulating substrate processing technology, specifically relating to insulating substrate positioning equipment for resistance screen printing machines. Background Technology

[0002] Screen printing is a relatively mature printing process. In the screen printing process, the two ends of the columnar insulating substrate are first placed on the positioning seats while the middle is suspended. The screen is lowered by the lifting module to contact the columnar insulating substrate. The cylinder drives the squeegee to contact the screen. Then the screen is moved laterally by the transverse module, and the squeegee remains stationary during the transverse movement. The insulating substrate is driven to roll by the screen, thereby screen printing the resistive paste on the circumferential surface of the substrate. In this printing method, the insulating substrate cannot rotate on its own. Therefore, there will be rolling resistance when the insulating substrate is driven to roll. If the pressure of the screen is insufficient, it will not be able to drive the insulating substrate to roll, which will affect the printing effect. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an insulating substrate positioning device for a resistance screen printing machine, which enables the insulating substrate to rotate autonomously without rolling resistance, thereby increasing the printing effect.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an insulating substrate positioning device for a resistance screen printing machine, including a support assembly, a clamp, a clamping element and two racks. The clamp and clamping element are horizontally symmetrically placed on both sides of the support assembly, and the two racks are symmetrically installed on both sides of the printing screen frame. The clamping ends of the clamp and clamping element are respectively provided with drive gears that mesh with the two racks. The support assembly includes a lead screw driver and two lifting frames, and the two lifting frames are symmetrically installed on the driving end of the lead screw driver.

[0005] The clamp includes a fixed base, a rotating tube, a drive cylinder, and a clamping rod. The fixed base is located on one side of the support assembly. The rotating tube is rotatably mounted on the fixed base. The drive cylinder is mounted on the fixed base. The drive end of the drive cylinder is rotatably connected to the clamping rod on the same axis. The clamping rod is slidably mounted inside the rotating tube. A limiting block is provided on the outer wall of the clamping rod. A guide groove that slidably engages with the limiting block is provided inside the rotating tube. The drive gear is sleeved on the rotating tube and is fixedly connected to the rotating tube on the same axis.

[0006] The clamping end of the clamping rod is equipped with an anti-slip rubber pad.

[0007] The clamping component includes a mounting base and a rotating rod. The mounting base is located on one side of the support assembly and is fixedly installed with the clamp. The rotating rod is rotatably mounted on the mounting base. The drive gear is sleeved on the rotating rod and is coaxially and fixedly connected with the rotating rod. An auxiliary clamping plate is provided on the side of the rotating rod facing the clamp.

[0008] Two guide rails are provided between the two racks, and the two guide rails are respectively located below the two sets of clamping assemblies. A rotating ring that rotatably fits the guide rails is rotatably sleeved on the clamping assembly.

[0009] The lead screw driver includes a transmission lead screw and a fixed frame. The transmission lead screw is rotatably mounted on the fixed frame. The transmission lead screw is divided into two threaded segments along its center line. The two threaded segments rotate in opposite directions. The fixed frame is provided with a knob for driving the transmission lead screw to rotate. The fixed frame is provided with guide rods on both sides of the transmission lead screw. The bottom of the lifting frame is provided with a transmission block that cooperates with the transmission lead screw and a guide block that cooperates with the guide rods.

[0010] The lifting frame includes a lifting cylinder and a support frame. The support frame is installed on the lifting end of the lifting cylinder, and guide rollers are installed on the support frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model relates to an insulating substrate positioning device for a resistance screen printing machine. During printing, the positioning device is placed below the printing screen frame, and the insulating substrate is placed on a support assembly for clamping by a clamping device and a clamping component. The support assembly drives the insulating substrate to rise and position it between the clamping device and the clamping component, where it is then clamped. The printing screen frame descends, causing the rack and pinion to mesh with the drive gear. During printing, the printing screen frame moves laterally, and through the engagement of the rack and pinion and the drive gear, the clamping ends of the clamping device and the clamping component drive the insulating substrate to rotate. This allows the insulating substrate to rotate autonomously without rolling resistance, thus improving the printing effect. Attached Figure Description

[0022] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0023] like Figures 1-8As shown, this embodiment provides an insulating substrate positioning device for a resistance screen printing machine, including a support assembly 1, a clamp 3, a clamping member 4, and two racks 2. The clamp 3 and clamping member 4 are horizontally symmetrically positioned on both sides of the support assembly 1, and the two racks 2 are symmetrically installed on both sides of the printing screen frame 6. The clamping ends of the clamp 3 and clamping member 4 are respectively provided with drive gears 5 that mesh with the two racks 2. The support assembly 1 includes a lead screw driver 7 and two lifting frames 8, which are symmetrically installed on the driving end of the lead screw driver 7. Specifically, it also includes a lifting rodless cylinder and a lead screw driver for driving the printing screen frame 6 to move up and down and laterally horizontally. During printing, the positioning device is placed below the printing screen frame 6, and the insulating substrate is placed on the support assembly 1 for clamping by the clamping device 3 and the clamping member 4. The support assembly 1 drives the insulating substrate to rise and place it between the clamping device 3 and the clamping member 4, and then clamps it by the clamping device 3 and the clamping member 4. The printing screen frame 6 descends, causing the rack 2 to mesh with the drive gear 5. That is, sensors are installed on the fixed base 9 and the printing screen frame 6 respectively (not shown in the figure), and the sensor positioning is a conventional technical means, so that the printing screen frame 6 can be positioned in real time with the fixed base 9 when it descends, ensuring stable meshing of the rack 2 and the drive gear 5. The sensor is a laser displacement sensor, and the installation position is perpendicular to the meshing point of the rack 2 and the drive gear 5. During printing, the printing screen frame 6 moves laterally, and through the cooperation of the rack 2 and the drive gear 5, the clamping ends of the clamping device 3 and the clamping member 4 drive the insulating substrate to rotate, so that the insulating substrate can rotate autonomously without rolling resistance, thus improving the printing effect.

[0024] Furthermore, the clamp 3 includes a fixed base 9, a rotating tube 11, a drive cylinder 12, and a clamping rod 10. The fixed base 9 is located on one side of the support assembly 1. The rotating tube 11 is rotatably mounted on the fixed base 9, i.e., the top of the fixed base 9 is provided with a rotating groove, the rotating tube 11 is disposed in the rotating groove, and the outer wall of the rotating tube 11 is provided with a limiting ring. The fixed base 9 is provided with a limiting groove that cooperates with the limiting ring. The drive cylinder 12 is mounted on the fixed base 9, and the drive end of the drive cylinder 12 is coaxially rotatably connected to the clamping rod 10. The clamping rod 10 is slidably disposed in the rotating tube 11. The outer wall of the clamping rod 10 is provided with a limiting block 13. The inside of the rotating tube 11 is provided with a guide groove 14 that slidably cooperates with the limiting block 13. The drive gear 5 is sleeved on the rotating tube 11 and is coaxially fixedly connected to the rotating tube 11. Specifically, an anti-slip rubber pad is installed on the clamping end of the clamping rod 10. The clamping rod 10 is pushed by the driving cylinder 12 to move along the rotating tube 11 and is clamped and fixed to the insulating substrate in conjunction with the clamping member 4 on the other side. When rotation is required, the printing screen frame 6 moves laterally and is connected by the rack 2 and the driving gear 5, so that the driving gear 5 drives the rotating tube 11 to rotate, thereby driving the clamping rod 10 to rotate.

[0025] Furthermore, the clamping component 4 includes a mounting base 15 and a rotating rod 16. The mounting base 15 is located on one side of the support assembly 1 and is fixedly installed with the clamp 3. The rotating rod 16 is rotatably mounted on the mounting base 15. The drive gear 5 is sleeved on the rotating rod 16 and is coaxially fixedly connected to the rotating rod 16. An auxiliary clamping plate 17 is provided on the side of the rotating rod 16 facing the clamp 3. The insulating substrate is clamped and fixed by the drive of the clamp 3 on the other side, thereby cooperating with the rotating rod 16. When rotation is required, the printing screen frame 6 moves laterally. Through the cooperation of the rack 2 and the drive gear 5, the drive gear 5 drives the rotating rod 16 to rotate. Due to the stable lateral movement of the printing screen frame 6, the racks 2 on both sides will drive the drive gears 5 on both sides to rotate at a uniform speed, so that the rotation speed is consistent with the lateral movement speed of the printing screen frame 6, preventing uneven speed and printing errors.

[0026] Furthermore, the lead screw driver 7 includes a transmission lead screw 18 and a fixed frame 19. The transmission lead screw 18 is rotatably mounted on the fixed frame 19 and is divided into two threaded segments along its center line. The two threaded segments rotate in opposite directions. The fixed frame 19 is provided with a knob 23 for driving the transmission lead screw 18 to rotate. The fixed frame 19 is provided with guide rods 20 on both sides of the transmission lead screw 18. The bottom of the lifting frame 8 is provided with a transmission block 21 that cooperates with the transmission lead screw 18 and a guide block 22 that cooperates with the guide rods 20. By rotating the knob 23, the transmission lead screw 18 is driven to rotate. Through the threaded engagement with the transmission block 21, the lifting frame 8 is driven to move, thereby adjusting the distance between the two lifting frames 8 to accommodate insulating substrates of different diameters.

[0027] Furthermore, the lifting frame 8 includes a lifting cylinder 24 and a support frame 25. The support frame 25 is mounted on the lifting end of the lifting cylinder 24, and guide rollers are installed on the support frame 25. The height of the support frame 25 is adjusted by driving the lifting cylinder 24 to lift and lower, and then supported by the guide rollers.
