Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp production and manufacturing, in particular to an automatic screen wiping device and an automatic screen wiping system for a thick film production line. Background Art

[0002] Integrated circuits are divided into thick film circuits, thin film circuits and semiconductor integrated circuits. Thick film circuits refer to integrated circuits that are constructed by using array film technology to make passive networks on the same substrate and assembling discrete semiconductor devices, monolithic integrated circuits or microcomponents.

[0003] Because thick film circuits generally use screen printing technology, ceramics are usually used as substrates. Because ceramics have very good heat resistance, and LED lamps have a large heat generation, thick film circuits are also widely used in the production of LED lamps.

[0004] When thick film circuits are printed on ceramic workpieces, long-term printing will cause the scraper to wear out. When the scraper is worn, the scraper and the screen cannot be in linear contact, so the ink on the screen cannot be scraped clean every time. There is a certain amount of ink left at the bottom of the screen, which will cause the screen to become fuzzy over time. In order to ensure the accuracy requirements, the screen needs to be wiped at all times to ensure that the screen does not block the holes and there is no residue at the bottom.

[0005] However, the screen wiping used in ordinary production lines of the prior art has many disadvantages. First, a motor is often used to drive the screen wiping to and fro, which has a complex structure and occupies a large space, making the replacement and assembly of parts very cumbersome; secondly, the screen wiping is done manually, which wastes manpower and there is a risk of clogging the holes due to untimely cleaning of the screen. Utility Model Content

[0006] In view of the shortcomings of the prior art mentioned above, the technical problem to be solved by the utility model is to provide an automatic screen wiping device and an automatic screen wiping system for a thick film production line, so as to solve the problems of large space occupied and complicated assembly and disassembly caused by the complex screen wiping structure in the prior art, as well as the waste of manpower and the risk of hole clogging caused by manual screen wiping.

[0010] The screen wiping assembly includes a scraper mechanism and a wiping mechanism arranged on the screen wiping bottom plate. When the screen wiping bottom plate slides on the guide rail assembly, the scraper mechanism scrapes the residual printing ink on the screen back and forth, and the scraped printing ink is wiped by the wiping mechanism.

[0011] As a more preferred embodiment, the scraper mechanism includes a scraper mounting seat arranged on the screen wiping base plate and a scraper blade arranged on the scraper mounting seat. When the screen wiping base plate slides on the guide rail assembly, the scraper blade is used to scrape off the residual printing ink on the screen.

[0013] As a more preferred embodiment, the wiping fixed seat includes two wiping fixed plates which are arranged opposite to each other, and both ends of the incoming material rod and the receiving material rod are rotatably arranged on the two wiping fixed plates respectively.

[0014] As a more preferred embodiment, the wiping mechanism includes a ball plunger, and the incoming material rod is rotatably set on the wiping fixed seat by the ball plunger, thereby increasing the driven resistance of the incoming material rod and preventing the incoming material rod from rotating with the receiving material rod. When the receiving material rod stops rotating, the wiping consumables on the incoming material rod rush out due to inertia, and the resistance of the incoming material rod is controlled by adjusting the tightness of the ball plunger, so that the wiping consumables remain in a tensioned state.

[0015] As a more preferred manner, the material receiving rod is further provided with a detachable material receiving clamping plate, and the material receiving clamping plate is used to cooperate with the material receiving rod to clamp the other end of the wiping consumable.

[0016] As a more preferred embodiment, one end of the material receiving rod is provided with a special-shaped opening that cooperates with the material receiving drive member, and the driving shaft of the material receiving drive member is connected to the material receiving rod by extending into the special-shaped opening, and the driving shaft of the material receiving drive member rotates to drive the material receiving rod to rotate.

[0017] As a more preferred manner, a knob plunger is also provided on the material receiving rod, and a circular opening adapted to the knob plunger is opened at the other end of the material receiving rod. On the other side of the wiping fixed plate, the knob plunger is inserted or pulled out from the other end of the material receiving rod to achieve a quick assembly and disassembly effect.

[0022] A moving device is arranged on the supporting table and can move along the direction of the guide rail assembly. A second electromagnet adapted to the second magnetic attraction member is arranged on the moving device. When the second electromagnet is energized, the second electromagnet generates suction and adsorbs the second magnetic attraction member. The scraper mechanism and the wiping mechanism on the screen wiping bottom plate are driven by the moving device to slide along the guide rail assembly. The scraper mechanism is used to scrape off the residual printing ink on the screen and the wiping mechanism is used to wipe the printing ink.

[0023] In order to better solve the above problems, the moving device also includes a jig moving component and a jig slidably arranged on the jig moving component, the second electromagnet is arranged on the jig, the jig moving component is arranged below the support table, and the support table is provided with an avoidance groove that allows the jig to pass through and move.

At the same time, the arrangement of the first magnetic attraction member and the second magnetic attraction member is more convenient for assembly and disassembly than the arrangement of the traditional mechanical transmission.

[0025] The automatic screen wiping system of the thick film production line of the utility model utilizes the above-mentioned automatic screen wiping device to realize the adsorption of the corresponding first magnetic attraction member and the second magnetic attraction member on the screen wiping bottom plate through the on-off control of the first electromagnet and the second electromagnet during operation, thereby driving the screen wiping bottom plate to slide on the guide rail assembly, and the scraper mechanism scrapes the residual printing ink on the screen while the wiping mechanism is used to wipe the printing ink. Compared with the traditional manual screen wiping solution, the wiping mechanism is used to wipe the printing ink in real time, which reduces manpower waste and also reduces the risk of hole blockage.

[0026] The automatic screen wiping device and the automatic screen wiping system of the thick film production line of the utility model drive the scraper mechanism and the wiping mechanism by magnetic attraction, thus avoiding a complicated transmission structure and making the structure more compact; and the wiping mechanism that wipes the printing ink in real time also reduces the waste of manpower and the risk of hole clogging; it solves the problems of large space occupation and complicated assembly and disassembly caused by the complex screen wiping structure in the prior art, as well as the waste of manpower and the risk of hole clogging caused by manual screen wiping.
