Description

Technical Field

[0001] The utility model relates to the technical field of screen printing machines, in particular to a screen printing machine with an anti-deviation mechanism. Background Art

[0002] Silk screen printing machine, also known as screen printing machine, is an important equipment in the printing industry. It is mainly used for printing various patterns and logos, such as trademarks, slogans, advertisements, etc. Silk screen printing machine can be classified in many ways according to its printing method, degree of automation and printing color. For example, according to the printing method, it can be divided into flat screen printing machine and curved screen printing machine; according to the degree of automation, it can be divided into manual screen printing machine and automatic screen printing machine; according to the printing color, it can be divided into monochrome screen printing machine and multi-color screen printing machine.

[0003] As disclosed in a Chinese patent: an anti-deviating screen printer, application number: CN202321651962.4, comprising: a cushion pasted on the upper end surface of the frame, a fixed cylinder fixed inside the frame, and a piston plate movably arranged inside the fixed cylinder, a blow pipe passing through one side of the fixed cylinder, and a cleaning strip connected to the end of the blow pipe away from the fixed cylinder, an air outlet is provided on the side of the cleaning strip, and a fixed cavity is arranged inside the cleaning strip; an air suction pipe fixedly passing through the other side of the fixed cylinder, and the end of the air suction pipe away from the fixed cylinder is fixedly connected to the box body in the frame. The anti-deviating screen printer can not only ensure the stability of the circuit board after it is placed, and prevent the displacement of its position caused by the force applied to the circuit board during the screen printing process, but also clean the dust and impurities adhering to the circuit board before screen printing to avoid uneven patterns.

[0004] However, in the above technical solution, when the material is adsorbed and fixed, a negative pressure state is created at the piston plate, and then the air between the fixing holes and the material is pumped into the connecting chamber for adsorption and fixation. This leads to certain requirements on the size of the material. The material must be able to cover all the fixing holes so that the piston plate can be in a negative pressure state. Once the material is small, resulting in excess fixing holes not being covered, external air can enter the piston plate through these excess fixing holes, and the piston plate will not be in a negative pressure state, thereby failing to adsorb and fix the material. Therefore, it is impossible to adsorb and fix materials of different sizes, and the scope of application is narrow. Utility Model Content

[0005] The main purpose of the utility model is to provide a screen printing machine with an anti-drift mechanism, which can effectively solve the problem in the background technology that when the material is adsorbed and fixed, the piston plate is made to be in a negative pressure state, and then the air between the fixing hole and the material is sucked into the connecting chamber for adsorption and fixation. This leads to certain requirements on the size of the material. The material must be able to cover all the fixing holes to make the piston plate in a negative pressure state. Once the material is small, there will be extra fixing holes not covered, and external air can enter the piston plate through these extra fixing holes. The piston plate will not be in a negative pressure state, so the material cannot be adsorbed and fixed. Therefore, it is impossible to adsorb and fix materials of different sizes, and the application range is narrow.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A screen printer with an anti-deviating mechanism comprises a base, a dual-axis movable platform and a plurality of through slots are arranged on the base, ventilation equipment is arranged in the through slots, a threaded groove is arranged on one side below the through slots, a groove is arranged in the base, an air pump is arranged on one side of the groove, a soft pad with holes is arranged on one side of the base, the soft pad with holes is adhered to the upper end surface of the base, and a screen box and a scraper are arranged on the dual-axis movable platform.

[0008] Preferably, the thread groove is communicated with the through groove and the recessed groove.

[0009] Preferably, the ventilation device is provided with a rotating ring rotatably arranged in the through groove, a warning light and a rotating slot are arranged on the upper side of the rotating ring, a touch sensor and a guide groove are arranged on the lower side of the rotating ring, and a guide slider is slidably arranged in the guide groove.

[0010] Preferably, the ventilation device is provided with a hollow threaded column in the thread groove, a sealing plate is fixedly provided on the side of the hollow threaded column away from the rotating ring, a plurality of air holes are provided on the side of the hollow threaded column close to the sealing plate, and a plurality of sealing layers are provided on the side of the sealing plate close to the hollow threaded column.

[0011] Preferably, the touch sensor is electrically connected to the warning light, and the guide slider is fixedly connected to the hollow threaded column.

[0012] Preferably, the sealing plate is located in the groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The utility model firstly adheres the perforated cushion to the upper end surface of the base, and at the same time makes the holes on the perforated cushion communicate with the inner cavity of the rotating ring. Then, if there is redundant ventilation equipment, the rotating ring is rotated by rotating the slot, so that the sealing plate fits the inner wall surface of the groove, and the threaded groove is sealed by the sealing plate to complete the sealing of the redundant ventilation equipment, so that the redundant ventilation equipment cannot affect the groove. Subsequently, the material is placed on the perforated cushion, and the air in the groove is extracted by an air pump, so that the groove is in a negative pressure state. The groove extracts the air at the holes on the perforated cushion through the ventilation equipment, thereby adsorbing and fixing the material. Materials of various sizes can be adsorbed and fixed, thereby increasing the scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3As shown, a screen printing machine with an anti-deviating mechanism comprises a base 1, on which a two-axis movable platform 2 and a plurality of through grooves 3 are arranged, in which ventilation equipment 4 is arranged, a threaded groove 5 is arranged on one side below the through groove 3, a groove 6 is arranged in the base 1, an air pump 7 is arranged on one side of the groove 6, a perforated cushion 8 is arranged on one side of the base 1, and the perforated cushion 8 is pasted on the upper end surface of the base 1, and a screen box 9 and a scraper 10 are arranged on the two-axis movable platform 2.

[0022] like Figure 4 As shown, in another embodiment of the utility model, the ventilation device 4 is rotatably provided with a rotating ring 401 in the through groove 3, a warning light 402 and a rotating slot 403 are provided on one side above the rotating ring 401, a touch sensor 404 and a guide slot 405 are provided on one side below the rotating ring 401, and a guide slider 406 is slidably provided in the guide slot 405;

[0023] The ventilation device 4 is provided with a hollow threaded column 407 in the threaded groove 5, a sealing plate 408 is fixedly provided on the side of the hollow threaded column 407 away from the rotating ring 401, a plurality of air holes 409 are provided on the side of the hollow threaded column 407 close to the sealing plate 408, and a plurality of sealing layers 4010 are provided on the side of the sealing plate 408 close to the hollow threaded column 407. When the ventilation device 4 needs to be sealed, the rotating ring 401 is first rotated by rotating the slot 403, and then the rotating ring 401 drives the hollow threaded column 407 to rotate through the guide slot 405 and the guide slider 406, and then the hollow threaded column 407 is moved upward through the threaded groove 5. The hollow threaded column 407 drives the sealing plate 408 to move, so that the sealing plate 408 gradually fits the inner wall surface of the groove 6. When the sealing plate 408 fits the inner wall surface of the groove 6, the air hole 409 enters the threaded groove 5, and the upper end surface of the hollow threaded column 407 fits the lower end surface of the rotating ring 401. The sealing plate 408 closes the threaded groove 5, completing the closure of the ventilation equipment 4, so that the redundant ventilation equipment 4 cannot affect the groove 6. At the same time, when the upper end surface of the hollow threaded column 407 fits the lower end surface of the rotating ring 401, it will touch the touch sensor 404, and then the touch sensor 404 will start the prompt light 402, thereby prompting through the prompt light 402 that the ventilation equipment 4 has been closed.

[0024] The working principle of a screen printing machine with an anti-deviation mechanism:

[0025] When in use, first stick the perforated cushion 8 to the upper end surface of the base 1, and at the same time make the holes on the perforated cushion 8 communicate with the inner cavity of the rotating ring 401. Then, if there are extra ventilation devices 4, the rotating ring 401 is rotated by rotating the slot 403, and then the rotating ring 401 drives the hollow threaded column 407 to rotate through the guide slide groove 405 and the guide slider 406, and then the hollow threaded column 407 is moved upward through the threaded groove 5, and the hollow threaded column 407 drives the sealing plate 408 to move, so that the sealing plate 408 gradually fits the inner wall surface of the groove 6. When the sealing plate 408 fits the inner wall surface of the groove 6, the air hole 409 enters the threaded groove 5, the upper end surface of the hollow threaded column 407 fits the lower end surface of the rotating ring 401, and the sealing plate 408 is against the threaded groove 5. The sealing is performed to complete the sealing of the redundant ventilation device 4, so that the redundant ventilation device 4 cannot affect the groove 6. At the same time, when the upper end face of the hollow threaded column 407 is in contact with the lower end face of the rotating ring 401, it will touch the touch sensor 404, and then the touch sensor 404 will start the prompt light 402, so that the prompt light 402 prompts that the ventilation device 4 has been closed, and then the material is placed on the perforated cushion 8, and then the air in the groove 6 is extracted by the air pump 7, so that the groove 6 is in a negative pressure state, and the groove 6 extracts the air at the holes of the perforated cushion 8 through the ventilation device 4, so that the material is adsorbed and fixed, and then the dual-axis movable table 2, the mesh box 9 and the scraper 10 can be used for silk screen printing, and materials of various sizes can be adsorbed and fixed, thereby increasing the scope of application.

[0026] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
