TECHNICAL FIELD
[0001] The utility model belongs to the technical field of wrapping wire processing, specifically relates to polyimide film wrapping copper flat wire cleaning device. BACKGROUND
[0002] In order to guarantee the binding force between polyimide film and copper flat wire, usually need to polish copper flat wire to remove surface dirt, oxidation layer and other impurities. Because the surface of polished copper flat wire will remain some dust (main component is copper powder), in order to guarantee the binding force between polyimide film and copper flat wire, need to remove the residual dust before wrapping polyimide film.
[0003] The dust removal mode includes spray cleaning method, soaking cleaning method, because the spray cleaning method is slow, therefore, in the pursuit of cleaning progress, generally adopt soaking cleaning method. When soaking cleaning, pour cleaning liquid into the cleaning box, the both ends of cleaning box are provided with perforations, copper flat wire enters the cleaning box through the perforation at one end of cleaning box and then leaves the cleaning box through the perforation at the other end of cleaning box. In some cases, in order to avoid the leakage of cleaning liquid through the perforation, need to set the plugging device at the perforation, remove the plugging device when operating copper flat wire to pass through the perforation, the operation is more complex, at the same time, a little cleaning liquid is easy to leak in the time period when removing the plugging device. UTILITY MODEL CONTENTS
[0004] In view of the deficiency of prior art, the utility model aims at providing polyimide film wrapping copper flat wire cleaning device, which is used to solve the problems in the above background.
[0005] In order to solve the above technical problems, the utility model provides polyimide film wrapping copper flat wire cleaning device, which comprises:
[0006] The liquid storage tank has a liquid storage cavity with an opening facing upward, the liquid storage cavity is used for storing cleaning liquid, along the length direction of the liquid storage cavity, a plurality of inlet holes communicated with the liquid storage cavity are arranged at one end of the liquid storage tank, and a plurality of outlet holes communicated with the liquid storage cavity are arranged at the other end of the liquid storage tank;
[0007] The driving member is installed at the bottom wall of the liquid storage cavity;
[0008] And the lifting plate is installed on the driving member, and the driving member can drive the lifting plate to move in the vertical direction to adjust the distribution range of the cleaning liquid;
[0009] The size of the inlet hole section and the size of the outlet hole section are both matched with the size of the copper flat wire section.
[0010] With this design, initially, the cleaning fluid does not submerge the inlet and outlet openings. After a portion of the copper flat wire is inserted into the storage chamber through the inlet and exits through the outlet, the drive unit moves the lifting plate upward. The lifting plate pushes the cleaning fluid to submerge the copper flat wire, thus preventing a small amount of cleaning fluid from leaking out during the process of the copper flat wire entering and leaving the storage chamber.
[0011] Preferably, it also includes two clamping parts, each of which is connected to the liquid storage tank via a driving part. The driving part can drive the clamping parts to move in the vertical direction, and the two clamping parts are symmetrically arranged along the length of the liquid storage chamber.

[0014] The inlet and outlet ports at both ends of the liquid storage tank are arranged in parallel along the width of the liquid storage tank.
[0015] With this design, after the clamping part holds the copper flat wire, the driving part drives the clamping part to move in the vertical direction so that the cleaning fluid flows. The flowing cleaning fluid can rinse the copper flat wire to improve the cleaning effect. When the lifting plate moves the cleaning fluid away from the copper flat wire, the driving part drives the clamping part to move in the vertical direction to shake off the cleaning fluid remaining on the copper flat wire.
[0016] Preferably, each inlet and outlet hole is provided with a sealing element on one side. The sealing elements are installed in the liquid storage tank. The sealing elements are elastic and have holes for copper flat wires to pass through.
[0017] This design further prevents cleaning fluid from leaking out through the inlet and outlet holes, and avoids minor leakage of cleaning fluid due to tiny gaps between the copper flat wire and the inlet and outlet hole walls.
[0018] Preferably, a baffle is connected to the top of the wall of the liquid storage chamber, and the baffle has perforations.
[0019] With this design, the baffle can impede the movement of the cleaning fluid, and can limit the flow of the cleaning fluid when it splashes during delivery.
[0020] Preferably, multiple baffles are provided, each of which is located at the bend at the top of the liquid storage chamber.
[0021] With this design, the baffle is placed at the bend at the top of the liquid storage chamber wall. The baffle can work with the two side walls in the liquid storage chamber wall to limit the cleaning liquid.
[0022] Preferably, a limiting component is also included, installed in the reservoir, to limit the spread of the cleaning fluid.
[0023] Through the design, the restriction assembly can limit the spreading range of the cleaning liquid, and reduce the difficulty of subsequent cleaning.

[0026] Each first restriction plate and each second restriction plate enclose a restriction cavity in communication with the liquid storage cavity.
[0027] Through the design, each first restriction plate and each second restriction plate enclose a restriction cavity for limiting the spreading range of the cleaning liquid; the second restriction plate is supported by the first restriction plate, instead of continuing to open grooves on the liquid storage tank to support the second restriction plate, thereby reducing the degree of modification of the liquid storage tank.
[0028] The beneficial effects of the utility model are as follows: initially, the cleaning liquid does not immerse into the inlet hole and outlet hole openings, after the copper flat wire part is inserted into the liquid storage cavity from the inlet hole and leaves the liquid storage cavity through the outlet hole, the driving member drives the lifting plate to move upward, the lifting plate pushes the cleaning liquid to immerse the copper flat wire, and a small amount of cleaning liquid is prevented from leaking out during the process of the copper flat wire entering and leaving the liquid storage cavity.

[0050] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments only are a part of the embodiments of the utility model, instead of all the embodiments.Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.
[0051] Embodiment 1
[0052] As Figures 1 to 9The utility model provides a polyimide film is wrapped copper flat wire with cleaning device, including:
[0053] The liquid storage tank 1 has a liquid storage cavity 11 with an opening facing upwards, the liquid storage cavity 11 is used to store cleaning liquid, along the length direction of the liquid storage cavity 11, the liquid storage tank 1 is provided with a plurality of inlet holes 13 communicated with the liquid storage cavity 11 at one end, and is provided with a plurality of outlet holes 14 communicated with the liquid storage cavity 11 at the other end;
[0054] The driving member 7 is installed at the bottom wall of the liquid storage cavity 11;
[0055] And the lifting plate 8 is installed on the driving member 7, and the driving member 7 can drive the lifting plate 8 to move along the vertical direction to adjust the distribution range of the cleaning liquid;
[0056] The size of the cross section of the inlet hole 13 and the size of the cross section of the outlet hole 14 are all matched with the size of the cross section of the copper flat wire.
[0057] The length direction of the liquid storage cavity 11 is the length direction of the liquid storage tank 1.
[0058] It needs to be emphasized that the application can only process a single copper flat wire, and at the same time, the application can process the copper flat wire after being wound on the winding disc, for the latter, the application can process multiple copper flat wires at the same time, and in the processing process, the existing unwinding device is used to unwind the copper flat wire, which is not described in detail.
[0059] Optionally, the liquid storage tank 1 and the liquid storage cavity 11 are in the shape of a rectangular parallelepiped.
[0060] Optionally, the cleaning liquid is clean water or a solution containing an appropriate amount of cleaning agent. The temperature of the cleaning liquid can be adjusted, and the cleaning liquid can use warm water. By selecting appropriate water temperature, the dirt can be softened, and the copper flat wire will not be damaged by heat. Generally, warm water (such as 40-60 degrees Celsius) has better effect; the cleaning liquid can also include an auxiliary cleaning agent. An appropriate amount of cleaning agent, such as a surfactant or an alkaline solution, is added to the warm water. These cleaning agents can enhance the dissolution and dispersion of copper powder and help the separation of copper powder and copper flat wire.
[0061] Optionally, the driving member 7 is provided as a pneumatic cylinder.
[0062] The size of the cross section of the lifting plate 8 is matched with the size of the cross section of the liquid storage cavity 11.
[0063] Initially, the cleaning liquid does not immerse the openings of the inlet hole 13 and the outlet hole 14. After the copper flat wire is inserted into the liquid storage cavity 11 from the inlet hole 13 and leaves the liquid storage cavity 11 through the outlet hole 14, the driving member 7 drives the lifting plate 8 to move upwards, and the lifting plate 8 pushes the cleaning liquid to immerse the copper flat wire, avoiding a small amount of cleaning liquid from leaking during the process of the copper flat wire entering and leaving the liquid storage cavity 11.
[0064] It needs to be explained that taking the copper flat wire as 200 meters and the length of the liquid storage cavity 11 as 5 meters as an example, after the part of the copper flat wire mentioned above leaves the liquid storage cavity 11 through the exit hole 14, the driving member 7 drives the lifting plate 8 to move upwards, and this part of the copper flat wire can be cleaned manually. At the same time, for the 5-meter part of the copper flat wire that is finally cleaned, the following method can be used to complete the cleaning: before this part completely enters the liquid storage cavity 11, the cleaning liquid needs to be moved downwards, and then the cleaning liquid is moved upwards after the blocking member made of rubber or other materials is gradually filled into the hole 13. Before this part completely moves out of the liquid storage cavity 11, the cleaning liquid needs to be moved downwards.
[0065] The size of the cross section of the inlet hole 13 and the size of the cross section of the exit hole 14 are matched with the size of the cross section of the copper flat wire, which can be considered as filling or approximately filling the copper flat wire into the inlet hole 13 and the exit hole 14, so as to completely avoid the leakage of the cleaning liquid through the inlet hole 13 and the exit hole 14 or only a small amount of cleaning liquid leaks through the inlet hole 13 and the exit hole 14.
[0066] If the cross section of the copper flat wire is square, the cross section of the inlet hole 13 and the exit hole 14 is also square.
[0067] Here, taking the height of the liquid storage cavity 11 as 100 centimeters as an example, initially, the distance between the top of the lifting plate 8 and the bottom wall of the liquid storage cavity 11 is 40 centimeters, and the distribution range of the cleaning liquid in the vertical direction is 30 centimeters. The lifting plate 8 drives the cleaning liquid to rise 10 centimeters in the vertical direction, so that the cleaning liquid immerses the copper flat wire.
[0068] It needs to be explained that when two structures are connected in sliding connection, the two structures can be connected in sliding connection through a sliding groove or the like, which is not described in detail in the prior art. When two structures are connected in rotation, the two structures can be connected in rotation through a rotating shaft or the like, which is not described in detail in the prior art. When two structures are connected, the two structures can be connected in detachable connection through a threaded connection or the like according to the actual situation, or can be connected in fixed connection through welding or the like, which is not described in detail in the prior art.
[0069] Embodiment 2
[0070] In this embodiment, two clamping parts 2 are also included, and the clamping parts 2 are connected to the liquid storage tank 1 through the driving part 4. The driving part 4 can drive the clamping parts 2 to move in the vertical direction. The two clamping parts 2 are symmetrically arranged along the length direction of the liquid storage cavity 11.
[0071] Each clamping part 2 has two clamping ends 21 on both sides of the material, and the clamping part 2 is used for clamping the copper flat wire.
[0072] In the vertical direction, each clamping end 21 is connected with a clamping plate 3 on the side close to the adjacent clamping end 21.
[0073] The inlet holes 13 and the outlet holes 14 are arranged in parallel along the width direction of the liquid storage tank 1.
[0074] Optionally, the clamping portions 2 are clamps, such as pneumatic mechanical clamps or electric mechanical clamps.
[0075] Initially, the copper flat wires are between the two clamping ends 21 of the clamping portions 2, and the two clamping portions 2 alternately clamp the copper flat wires to avoid affecting the overall cleaning of the copper flat wires due to the clamping of the clamping portions 2; after the clamping portions 2 clamp the copper flat wires, the driving portions 4 drive the clamping portions 2 to move in the vertical direction to make the cleaning liquid flow, and the flowing cleaning liquid can flush the copper flat wires to improve the cleaning effect; when the lifting plate 8 drives the cleaning liquid to move away from the copper flat wires, the driving portions 4 drive the clamping portions 2 to move in the vertical direction to shake off the cleaning liquid remaining on the copper flat wires.
[0076] After the cleaning liquid immerses the copper flat wires for a period of time, the two clamping portions 2 can also clamp the copper flat wires synchronously.
[0077] It should be noted that the clamping portions 2 and some devices described below can be controlled by a controller, which is not limited specifically herein.
[0078] Optionally, the clamping plates 3 are square plates and extend along the width direction of the liquid storage cavity 11.
[0079] The clamping plates 3 replace the clamping ends 21 to contact the copper flat wires, which can be regarded as that the clamping plates 3 and the clamping ends 21 form new clamping structures, which is equivalent to expanding the clamping surface of the clamping ends 21, so as to facilitate clamping more copper flat wires without using larger clamping ends 21.
[0080] Optionally, the driving portions 4 are electric sliding tables. Illustratively, the non-driving ends of the driving portions 4 are installed on the top of the liquid storage tank 1, and the driving ends of the driving portions 4 are installed on the clamping portions 2. The driving portions 4 are provided in two.
[0081] Embodiment 3
[0082] In this embodiment, the inlet holes 13 and the outlet holes 14 are provided with the plugging members 9 on one side, and the plugging members 9 are installed on the liquid storage tank 1. The plugging members 9 are elastic, and the plugging members 9 are provided with the holes 91 for the copper flat wires to pass through.
[0083] Optionally, the plugging members 9 are sponges or are made of rubber or other materials.
[0084] The plugging members 9 can further prevent the cleaning liquid from leaking out through the inlet holes 13 and the outlet holes 14, and avoid the leakage of a small amount of cleaning liquid due to the small gap between the copper flat wires and the hole walls of the inlet holes 13 and the outlet holes 14.
[0085] The cross-sectional dimensions of the copper flat wire are compatible with the cross-sectional dimensions of the inlet hole 13 and the outlet hole 14, but there may still be a small gap between them, such as the copper flat wire may deform and cause the gap to be generated.
[0086] The copper flat wire is passed through hole 91 and then through inlet hole 13. The sealing part 9 fits tightly against the copper flat wire to prevent the cleaning fluid from leaking out.
[0087] Example 4
[0088] In this embodiment, a baffle 5 is connected to the top of the wall of the liquid storage chamber 11, and the baffle 5 is provided with a perforation 51.
[0089] When delivering cleaning fluid, in some cases an infusion tube is used to deliver the cleaning fluid to the storage chamber 11. One end of the infusion tube is connected to the water pump, and the other end can be inserted into the perforation 51 to fix the infusion tube.
[0090] Taking baffle 5 as an example, other structures within this utility model are explained. The size, shape, and other settings of baffle 5 can be adjusted according to actual conditions and needs, and no specific limitations are imposed here.
[0091] Baffle 5 can impede the movement of cleaning fluid, and can limit the movement of cleaning fluid when it splashes during delivery.
[0092] Example 5
[0093] In this embodiment, multiple baffles 5 are provided, and each baffle 5 is located at the bend at the top of the liquid storage cavity 11.
[0094] The multiple baffles 5 are designed to accommodate situations where multiple infusion tubes are used, thereby improving the infusion progress.
[0095] It should be noted that in this utility model, "multiple" refers to two or more.
[0096] The baffle 5 is set at the top bend of the wall of the liquid storage chamber 11. The baffle 5 can work with the two side walls in the wall of the liquid storage chamber 11 to limit the cleaning liquid.
[0097] For example, the wall of the liquid storage chamber 11 includes four side walls, and four baffles 5 are provided, with baffles 5 provided in the contact area of any adjacent side walls.
[0098] Example 6
[0099] In this embodiment, a limiting component 6 is also included, which is installed in the liquid storage tank 1 to limit the distribution range of the cleaning liquid.
[0100] During the process of shaking off the cleaning fluid, some of the cleaning fluid will enter the reservoir 11 and some will spread outside the reservoir 11. The limiting component 6 can limit the spread of the cleaning fluid and reduce the difficulty of subsequent cleaning.
[0101] Embodiment 7
[0102] In the embodiment, along the width direction of the liquid storage cavity 11, the two ends of the top end of the liquid storage tank 1 are provided with the chute 12 opening upward, the chute 12 extends along the length direction of the liquid storage cavity 11, and the limiting assembly 6 includes two first limiting plates 61, and the two first limiting plates 61 are respectively inserted into the two chutes 12.

[0107] Each first limiting plate 61 and each second limiting plate 62 enclose to form a limiting cavity 63, and the limiting cavity 63 is used for limiting the spreading range of the cleaning liquid.
[0108] The second limiting plate 62 is supported by the first limiting plate 61, instead of continuing to open the chute 12 on the liquid storage tank 1 to support the second limiting plate 62, so as to reduce the degree of modification of the liquid storage tank 1.
[0109] The first limiting plate 61 can be separated from the chute 12, so as to facilitate selection of different sizes of the first limiting plate 61 and the second limiting plate 62 according to the moving range of the clamping part 2.
[0110] The second limiting plate 62 can be translated relative to the first limiting plate 61, so as to avoid affecting the delivery of the infusion tube, and a longer infusion tube does not need to be used.
