Description

Technical Field

[0001] This invention relates to the field of PCB surface treatment technology, and in particular to an automatic replacement device for adhesive paper in a PCB dust removal machine. Background Technology

[0002] During the production of circuit boards (PCBs), dust, particles, and other contaminants are generated on the surface. In order to improve the cleanliness of the circuit boards in subsequent processes such as soldering, assembly, or testing, dust removal operations are required.

[0003] like Figure 10 As shown, the currently used PCB dust collector 7 includes an inspection port equipped with an inspection cover 71. The PCB dust collector 7 has an internal PCB conveying mechanism that transports the PCBs during dust removal and passes them through... Figure 11 Between the two silicone rollers 75 respectively fitted on the outer sides of the two second rotating shafts 74 shown, the PCB dust collector 7 also has a pair of first rotating shafts 72. A sleeve roller 73 is fixed to the outer periphery of the first rotating shaft 72. The sleeve roller 73 is the component for mounting the adhesive paper. A complete set of adhesive paper includes a paper tube 8 and a paper roll wound around its outer periphery. The position of the first rotating shaft 72 can be automatically adjusted by the PCB dust collector 7 so that the outermost layer of the adhesive paper roll can remove the contaminants adsorbed on the silicone rollers 75. The PCB dust collector 7 also has the function of cutting the paper roll and removing waste paper. After the adhesive paper roll is used up, such as... Figure 11 As shown, only paper tube 8 remains at this point. Workers need to open the inspection cover 71, remove paper tube 8, and then place new adhesive paper onto the roller 73 before closing the inspection cover 71. Additionally, at the end of the PCB dust collector 7 furthest from the inspection port, multiple motors drive the first rotating shaft 72 and the second rotating shaft 74 respectively. Some PCB dust collectors 7 also have multiple rotating seats near the inspection port to support the first rotating shaft 72 and the second rotating shaft 74; however, these rotating seats can automatically detach when the adhesive paper needs to be replaced. During continuous production, workers need to repeat this action multiple times a day, consuming a significant amount of manpower. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides an automatic replacement device for adhesive paper in PCB dust removal machines, which can automatically and quickly complete the replacement of dust removal paper, saving manpower.

[0005] In order to achieve the objectives of this invention, the following technologies are proposed: An automatic adhesive paper replacement device for a PCB dust collector includes: A moving unit is used to move the replacement device; The temporary storage and retrieval unit is located at the top of the moving unit and includes a horizontal plate. A C-shaped groove is provided at the top of one side of the horizontal plate. Sliders are provided at the bottom of both ends of the horizontal plate. Several rollers are provided at the bottom of the sliders. A vertical plate is provided on the upper surface of the horizontal plate. A pair of U-shaped frames arranged vertically are provided on one side of the vertical plate for placing the adhesive paper. An ejection component is provided on the other side of the vertical plate for pushing the paper tube in the PCB dust collector outward. The material guiding unit is located on one side of the temporary storage and take-up unit. It includes a fourth linear mechanism whose output direction is perpendicular to the axis of the paper tube. Its output end is a second rotary motor. One end of the outer periphery of the output shaft of the second rotary motor is provided with a material guiding plate, which is used to guide the adhesive paper to the U-shaped frame located above or below. The material guiding plate matches the long side of the C-shaped groove. The material preparation unit is located on one side of the material guiding unit and includes an inclined U-shaped frame for placing multiple sets of adhesive paper. The lower end of the U-shaped frame is equipped with a lifting cover. The feeding unit, located at one end of the temporary storage and retrieval unit, is used to push the adhesive paper placed on the temporary storage and retrieval unit into the predetermined installation position inside the PCB dust collector.

[0006] Furthermore, the component includes a second linear mechanism located on the other side of the vertical plate, with its paper tube axis parallel to the vertical plate. The sliding end of the second linear mechanism is provided with a third linear mechanism parallel to it. The output end of the third linear mechanism is provided with two pairs of first rotary motors. The output end of the first rotary motors is provided with a rotating plate. One end of the rotating plate is provided with an arc plate that matches a portion of the arc of the paper tube cross-section.

[0007] Furthermore, the feeding unit includes a pair of sixth linear mechanisms arranged in the vertical direction. The output end of the sixth linear mechanism is provided with a push ring. The inner diameter of the push ring is larger than the outer diameter of the roller of the PCB dust collector and smaller than the outer diameter of the paper roll. A limiting arc is also provided on the upper part of one end of the push ring. The inner circumference of the limiting arc matches the outer circumference of the paper roll.

[0008] The beneficial effects of this technical solution are as follows: The automatic dust removal paper replacement device of this application can automatically remove the used paper tube and automatically load new dust removal paper, which can reduce a lot of manual operation, improve the level of automation, and save manpower.

A limiting arc 55 is also provided at the upper part of one end of the push ring 54. The inner circumference of the limiting arc 55 matches the outer circumference of the paper roll 9 to prevent the adhesive paper from falling between the temporary storage and take-up unit 2 and the PCB dust collector 7 without contacting the roller 73.

[0027] The cover opening and positioning unit 6 is fixed to one end of the PCB dust collector 7 and includes a fixing frame 61. The fixing frame 61 is equipped with a third rotary motor 62, whose output shaft is coaxial with the rotation shaft of the inspection cover 71 of the PCB dust collector 7. One end of the output shaft of the third rotary motor 62 is equipped with a rocking rod 63. The lower end of the rocking rod 63 is equipped with a seventh linear mechanism 64, whose output end is equipped with an insert plate 65 for inserting into the outer side of the inspection cover 71 and between its handle. The cover opening and positioning unit 6 also includes a C-shaped block 66. One end face of the C-shaped block 66 is provided with a positioning groove 67 that matches the positioning block 131.

[0028] The opening and positioning unit 6 can further improve the automation level of the replacement device, realize automatic opening, and facilitate the positioning of the main body of the replacement device, thereby improving the accuracy of adhesive paper replacement.

[0029] In this embodiment, the first linear mechanism 18, the third linear mechanism 25, the fourth linear mechanism 31, the fifth linear mechanism 45, the sixth linear mechanism 51, and the seventh linear mechanism 64 all use single-axis linear cylinders, while the second linear mechanism 24 uses a rodless linear cylinder.

[0030] Work style: First, the main body of the automatic adhesive paper replacement device, consisting of the moving unit 1, the temporary storage and retrieval unit 2, the guiding unit 3, the preparation unit 4, and the feeding unit 5, is moved to one end of the PCB dust collector 7 via the moving unit 1. Specifically, the positioning block 131 is brought into contact with the positioning groove 67 to make the main body more accurately positioned.

[0031] Then prepare some adhesive paper in advance in the herringbone frame 41, for example, put all the adhesive paper to be used that day into the herringbone frame 41.

[0032] Then, the insert plate 65 is inserted into the outer side of the inspection cover 71 and between its handle by the seventh linear mechanism 64, and then the inspection cover 71 is opened by the third rotary motor 62.

[0033] Next, the automatic replacement of the adhesive paper will begin. Of course, at this time, the PCB dust collector 7 has entered the state of replacing the adhesive paper. The obstructions outside the first rotating shaft 72 and the second rotating shaft 74 have been removed. The following is a detailed explanation.

[0034] First, the third linear mechanism 25 is brought closer to the PCB dust collector 7 by the second linear mechanism 24. Then, the mounting plate 251 is pushed into the PCB dust collector 7 by the third linear mechanism 25. Then, the first rotary motor 26 makes each arc plate 27 first tilt and then turn to a horizontal state, pulling each paper tube 8 out of the PCB dust collector 7 from one end. Then, the two paper tubes 8 slide into the waste tube frame 161 through the second guide inclined plate 29.

[0035] Then, the two dust removal papers prepared in the preparation unit 4 are transferred to the temporary storage and retrieval unit 2 via the guiding unit 3. Specifically, the dust removal papers are first placed onto the upper U-shaped frame 231, with the guide plate 35 at an angle as follows: Figure 3 As shown, the lifting cover 46 is opened by the fifth linear mechanism 45 to release a set of dust removal paper, and then the lifting cover 46 is closed. The dust removal paper falls into the upper U-shaped frame 231. Similarly, the guide plate 35 is rotated by the second rotary motor 33, and the above operation is repeated to place dust removal paper in the lower U-shaped frame 231.

[0036] Then, the guide plate 35 is rotated by the second rotary motor 33 to make it vertical. Then, the horizontal plate 21 is pushed to the end by the fourth linear mechanism 31. Then, the push ring 54 is controlled by the sixth linear mechanism 51 to push the dust removal paper. Since the distance between the main body of the automatic dust removal paper replacement device and the PCB dust removal machine 7 is not specified above, if the distance is far, the dust removal paper can be limited to prevent it from falling by rotating the arc plate 27 in the opposite direction to a horizontal state on the other side. After the dust removal paper is pushed to the predetermined position on the sleeve roller 73, it is removed from the feeding unit 5.

[0037] And so on, repeating the automatic replacement of the adhesive paper every predetermined time, such as every hour.

[0038] The above are only some of the embodiments listed in this application and are not intended to limit this application.
