Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing technology, and in particular to an impurity receiving device and a glue-applying unwinding machine. Background Technology

[0002] Printed Circuit Board (PCB) is a component used for electrical connections in electronic components. It mainly consists of an insulating substrate layer and a conductive layer. Copper-clad laminate is one of the main substrates of PCB, and its processing level directly affects the performance of PCB. The gluing machine and uncoiling machine are key equipment in the copper-clad laminate manufacturing process, and their performance directly affects the performance of printed circuit boards.

[0003] In related technologies, an air shaft first passes through a rolled paper or plastic tube containing reinforcing material. Compressed air then lifts the tensioning device inside the air shaft, securing it tightly to the inner wall of the tube. When the air shaft is placed on the gluing machine or uncoiler, it is first stabilized by a support frame on the base. A tightening mechanism on the base then tightens the air shaft, ensuring a tight fit between the grooves at both ends of the air shaft and the protrusions of the tightening mechanism. This allows the base to rotate synchronously with the air shaft. However, this structure suffers from friction between the grooves of the air shaft and the protrusions of the tightening mechanism, between the air shaft and the support frame, and between the air shaft and the paper or plastic tube. This friction can cause metal impurities, paper scraps, or plastic dust to fall onto the reinforcing material, creating internal impurities and affecting production quality. Utility Model Content

[0004] The purpose of this invention is to provide an impurity receiving device and a gluing unwinding machine, which can reduce the falling of impurities and ensure production quality.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] One aspect provides an impurity receiving device for receiving frictional impurities between an air shaft and a tightening mechanism, between the air shaft and a support frame, and between the air shaft and a paper tube. The tightening mechanism and the support frame are mounted on a base, with the support frame positioned below the tightening mechanism. The impurity receiving device comprises:

[0007] A fixed bearing is provided, which can be sleeved on the base and can rotate relative to the base.

[0008] A powder receiving box is fixed on the fixed bearing. The powder receiving box is located below the support frame with its opening facing upwards. The projection of the base and the support frame onto the powder receiving box falls inside the powder receiving box.

[0009] A counterweight is provided on the powder receiving box so that the powder receiving box is always located below the support frame and the opening of the powder receiving box faces upward during the movement of the air shaft.

[0010] In some embodiments, the powder receiving box is a groove-shaped box, and the counterweight is located on the outer top of the powder receiving box.

[0011] In some embodiments, the impurity receiving device further includes a first protective shell, one end of which is hinged to the powder receiving box, and the first protective shell and the powder receiving box are able to surround the air shaft between them.

[0012] In some embodiments, the powder receiving box is cylindrical.

[0013] In some embodiments, the impurity receiving device further includes a movable box, the inner wall of which is provided with a slide rail extending axially along the air expansion shaft, the movable box moves on the slide rail, and the opening of the movable box faces upward.

[0014] In some embodiments, the movable box is a slotted box.

[0015] In some embodiments, the impurity receiving device further includes a second protective housing, one end of which is hinged to the movable box, and the second protective housing and the movable box are capable of surrounding the support frame and the clamping mechanism between them.

[0016] In some embodiments, a first sealing plate is provided at the end of the movable box away from the fixed bearing, and a second sealing plate is provided at the end of the second protective shell away from the fixed bearing. The first sealing plate and the second sealing plate can close the end of the movable box away from the fixed bearing, and there is a gap between the first sealing plate, the second sealing plate and the outer wall of the paper tube.

[0017] In some embodiments, the powder receiving box is disposed on the outer peripheral surface of the fixed bearing, and the side of the fixed bearing is provided with a cover to cover the balls in the fixed bearing.

[0018] On the other hand, a gluing unwinding machine is also provided, which includes the base and the impurity receiving device as described above, and the fixed bearing is rotatably mounted on the base.

[0019] The beneficial effects of this utility model are:

[0020] By setting up the aforementioned impurity receiving device, the fixed bearing can fix the powder receiving box on the base. The powder receiving box is equipped with a counterweight, so that the air shaft can rotate on its own axis or, by changing the reinforcing material on the air shaft, drive the air shaft to revolve around the common axis. Thus, when the air shaft is flipped, the counterweight can always keep the powder receiving box below the support frame, and the opening of the powder receiving box is set upwards, so that impurities generated by friction can fall into the powder receiving box, effectively reducing the drift of impurities and improving production quality.

[0029] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 4 As shown, the existing gluing and unwinding machine has two opposing bases 200, each base 200 is equipped with a clamping mechanism 400. The clamping mechanism 400 can tightly engage the two ends of the air shaft 500 with the protruding position of the clamping mechanism 400, so as to fix the air shaft 500 from both ends for fixed alignment. This allows the air shaft 500 to rotate synchronously during the rotation of the base 200. During use, the friction between the air shaft 500 and the protruding position of the clamping mechanism 400 will generate impurities and debris. In order to ensure stability, a support frame 300 is also provided below the clamping mechanism 400. The support frame 300 can support the air shaft 500. Friction impurities will also occur between the support frame 300 and the air shaft 500, as well as between the air shaft 500 and the paper tube 600. Based on the above problems, such as Figure 3 As shown, the gluing and unwinding machine of this utility model includes not only the above-mentioned components, but also, as shown in the figure, Figure 1 and Figure 2The impurity receiving device 100 shown includes a fixed bearing 1, a powder receiving box 2, and a counterweight 3. The fixed bearing 1 can be sleeved on the base 200, and the fixed bearing 1 and the base 200 can rotate relative to each other. The powder receiving box 2 is fixed on the fixed bearing 1 and is located below the support frame 300 with its opening facing upward. The projection of the base 200 and the support frame 300 onto the powder receiving box 2 falls inside the powder receiving box 2. The counterweight 3 is located on the powder receiving box 2 so that during the movement of the air shaft 500, the powder receiving box 2 is always located below the support frame 300 with its opening facing upward.

[0034] By setting up the aforementioned impurity receiving device 100, the fixed bearing 1 can fix the powder receiving box 2 onto the base 200. The powder receiving box 2 is equipped with a counterweight 3, so that the air shaft 500 can rotate on its own axis or, by changing the reinforcing material on the air shaft 500, drive the air shaft 500 to revolve around the common axis. Thus, when the air shaft 500 is flipped, the counterweight 3 can always keep the powder receiving box 2 below the support frame 300, and the opening of the powder receiving box 2 is set upward, so that the impurities generated by friction can fall into the powder receiving box 2, effectively reducing the falling of impurities and improving production quality.

[0035] like Figure 1 As shown, in some embodiments, to better receive the aforementioned impurities, the toner receiving box 2 is a groove-shaped box, such as a U-shaped groove box, a rectangular groove box, or a polygonal box, to adapt to the shape of the air shaft 500. The counterweight 3 is set on the outer top of the toner receiving box 2, and the orthogonal projection of the base 200 and the support frame 300 onto the toner receiving box 2 falls inside the toner receiving box 2. It is understood that there is a gap between the air shaft 500 and the paper tube 600 and the toner receiving box 2 to avoid friction between them.

[0036] To reduce the upward drift of impurities from the opening of the powder receiving box 2, and further decrease the probability of impurities escaping from the powder receiving box 2, in some embodiments, the impurity receiving device 100 also includes a first protective shell 4. To accommodate the shape of the powder receiving box 2, the first protective shell 4 is a groove-shaped box, with one end hinged to the powder receiving box 2. This allows the first protective shell 4 and the powder receiving box 2 to be assembled into a complete cylindrical structure, enclosing the base 200 and the support frame 300 between them. Exemplarily, the first protective shell 4 and the powder receiving box 2 are connected by a hinge 5. Using the hinged connection between the first protective shell 4 and the powder receiving box 2 to surround the base 200 not only prevents impurities from drifting away but also facilitates the installation of the air shaft 500. Of course, in other alternative embodiments, the powder receiving box 2 can be directly cylindrical.

[0037] like Figure 1 and Figure 2As shown, in some embodiments, in order to effectively adjust the receiving range along the axial direction of the air expansion shaft 500, the impurity receiving device 100 further includes a movable box 6. The inner wall of the powder receiving box 2 is provided with a slide rail 7 extending along the axial direction of the air expansion shaft 500. The movable box 6 moves on the slide rail 7, and the opening of the movable box 6 is arranged facing upwards, so that when it is necessary to extend the receiving range, the movable box 6 can be extended from the powder receiving box 2 to extend the receiving range. In the current embodiment, the orthogonal projection of the base 200 and the support frame 300 onto the powder receiving box 2 falls within the movable box 6. In the current embodiment, in order to adapt to the shape of the air expansion shaft 500, the movable box 6 is a groove-shaped box. In some embodiments, in order to facilitate the fixing of the movable box 6, a locking member can also be provided on the movable box 6, so that when the powder receiving box 2 slides into place, the movable box 6 can be locked on the slide rail 7 by the locking member to prevent the movable box 6 from shaking or shifting. It is understood that the locking member is not specifically limited and can be, but is not limited to, bolts.

[0038] When the movable box 6 is removed from the powder receiving box 2, in order to reduce the dispersion of impurities from above the movable box 6, the impurity receiving device 100 further includes a second protective shell 8. One end of the second protective shell 8 is hinged to the movable box 6. The second protective shell 8 and the movable box 6 can surround the support frame 300 and the clamping mechanism 400 between them to reduce the dispersion of impurities. For example, the second protective shell 8 is a groove-shaped box, so that the second protective shell 8 and the movable box 6 form a cylindrical shape.

[0039] like Figure 1 As shown, since one end of the powder receiving box 2 is fixed to the fixed bearing 1, and based on the fact that the powder receiving box 2 is a groove-shaped box and the presence of the movable box 6, the end of the powder receiving box 2 away from the fixed bearing 1 can be blocked by the movable box 6. In order to reduce impurities from drifting out from the end of the movable box 6 away from the fixed bearing 1, a first sealing plate 9 is provided at the end of the movable box 6 away from the fixed bearing 1, and a second sealing plate 10 is provided at the end of the second protective shell 8 away from the fixed drawer. The first sealing plate 9 and the second sealing plate 10 can seal the end of the movable box 6 away from the fixed bearing 1. In the current embodiment, the first sealing plate 9 and the movable box 6 can be hinged, and the second sealing plate 10 and the second protective shell 8 can also be hinged, so that the first sealing plate 9 and the second sealing plate 10 can be opened for observation and cleaning. It can be understood that the edges of the first sealing plate 9 and the second sealing plate 10 have a certain gap with the air shaft 500 and the paper tube 600 to avoid unnecessary friction.

[0040] In some embodiments, for ease of fixing, the powder receiving box 2 is disposed on the outer peripheral surface of the fixed bearing 1. Thus, during the operation of the ball bearing 1, some impurities may drift out. In order to reduce the drift of the above-mentioned impurities, a cover 11 is provided on the side of the fixed bearing 1 to cover the ball bearing 1, thereby reducing the drift of impurities; and the cover 11 can also prevent lubricating oil leakage and avoid pollution.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
