Description

Technical Field

[0001] The utility model relates to the field of copper clad laminate production equipment, in particular to a contactless copper foil conveyor belt cleaning device. Background Art

[0002] In the copper clad laminate industry, the stacking process refers to using the specified copper foil to cover the prepared adhesive sheet according to the customer's order requirements, and then separating the combined materials with mirror steel plates and stacking them into books. In the stacking process equipment, the copper foil lead-out unwinding system is its important component.

[0003] The existing copper foil unwinding system is generally divided into two forms: one is tension copper foil unwinding, and the other is tension-free copper foil unwinding. Among them, the tension copper foil unwinding is that the traction roller pulls the copper foil to make the unwinding shaft passively unwind. At this time, the copper foil is under tension, and the unwinding shaft is equipped with a magnetic powder brake to control the tension. The tension-free copper foil unwinding is generally carried out by a servo motor with a reducer to actively unwind the rolled copper foil fixed by the chuck. The pulling and releasing of the copper foil are both active, and the copper foil in this section is in a tension-free state. The transportation of the copper foil is completed by a negative pressure conveyor belt.

[0004] At present, during the copper foil conveying process, the copper powder, copper scraps, copper wires, etc. of the copper foil will contaminate the conveyor belt, which will directly lead to the contamination of the product, so the conveyor belt needs to be cleaned. The existing conveyor belt cleaning method includes regular manual cleaning, that is, after the equipment has been running for a period of time, the belt is manually wiped according to the contamination status of the belt to clean the copper powder, copper scraps, copper wires, etc. on the belt. There is no special equipment to clean the belt online in real time, so the cleaning effect is limited. Another method is to use a sticky roller to adhere to foreign matter on the surface of the negative pressure conveyor belt, but because the sticky roller contacts the conveyor belt, and the conveyor belt contacts the copper foil, in order to avoid the adhesive on the sticky roller from falling off, a sticky roller with too strong viscosity cannot be used. Therefore, the sticky roller has limited cleaning effect on the adhesion of foreign matter on the conveyor belt, and needs to be replaced regularly, which is inconvenient for manual operation and has high management costs. Another way is to use negative pressure vacuum to adsorb copper powder, copper chips, copper wire, etc. on the conveyor belt. However, since the tension-free copper foil unwinding conveyor belt is a perforated conveyor belt, the porous surface of the conveyor belt has a greater impact on the maintenance of negative pressure, so the adsorption effect is limited, resulting in limited cleaning effect.

[0005] Therefore, it is necessary to provide a cleaning device that can improve the cleaning effect of the perforated conveyor belt to solve the above problems. Utility Model Content

[0032] Combination Figure 1-Figure 13As shown, the contactless copper foil conveyor belt cleaning device 100 provided by the utility model is installed corresponding to the driving roller 210 of the copper foil conveyor belt 220, and is used to clean the conveyor belt 220 wound on the driving roller 210. The cleaning device 100 is particularly suitable for cleaning the conveyor belt 220 with holes, but it is not limited to this, and it is also feasible to be used for cleaning other conveyor belts. The other structures of the copper foil conveyor device 200 involved in the utility model, except for the driving roller 210 and the conveyor belt 220, are all conventional structures in the field and will not be described in detail.

[0033] Continue to combine Figure 1-Figure 13 As shown, the contactless copper foil conveyor belt cleaning device 100 in the utility model includes a negative pressure adsorption unit 110 and a negative pressure generator (not shown). The negative pressure adsorption unit 110 includes a first box body 111 and a baffle, the first box body 111 is a hollow structure and one side of it is provided with an opening 1111, the baffle is installed at the upper end or / and the lower end of the side where the opening 1111 of the first box body 111 is located, the baffle is inclined and movably connected to the first box body 111, the first box body 111 is wrapped around the outside of the driving roller 210 through its opening 1111, and the baffle is located above or / and below the conveyor belt 220 wound around the driving roller 210, and the gap between it and the conveyor belt 220 is adjusted by moving the baffle. The negative pressure generator is connected to the first box body 111, and is used to provide negative pressure power to the first box body 111 to form a negative pressure cavity therein, so as to adsorb impurities such as copper powder, copper chips, copper wire, etc. on the conveyor belt 220. The utility model installs the negative pressure adsorption unit 110 corresponding to the driving roller 210 of the copper foil conveyor belt 220, thereby reducing the influence of the porous surface of the conveyor belt 220 on the negative pressure maintenance, enhancing the adsorption effect, and thus improving the cleaning effect.

[0034] In the present invention, the negative pressure generator preferably uses a large-flow vacuum generator to obtain a convenient and stable negative pressure power source, but is not limited thereto.

[0035] Combine the following Figure 1-6 , Figure 10-12 As shown, in one embodiment of the present invention, the upper and lower ends of the opening 1111 of the first box body 111 are respectively provided with baffles. For the convenience of subsequent description, the two baffles are respectively referred to as the first baffle 112a and the second baffle 112b. In this embodiment, the inclination direction of the first baffle 112a and the second baffle 112b are both staggered with the conveying surface of the conveyor belt 220. Figure 1As shown. Specifically, the first baffle 112a is installed on the top of the first box body 111 and tilted downward, and the second baffle 112b is installed on the bottom of the first box body 111 and tilted upward. After the first box body 111 is installed, the conveyor belt 220 is led out from its opening 1111, and the first baffle 112a is located above the upper conveying surface of the conveyor belt 220, and the second baffle 112b is located below the lower conveying surface of the conveyor belt 220. Therefore, the movement of the first baffle 112a and the second baffle 112b can adjust the gap between them and the conveyor belt 220. The smaller the gap, the greater the negative pressure adsorption force and the better the cleaning effect. The larger the gap, the higher the safety. Therefore, the gap can be adjusted according to production needs to achieve the adjustment of the cleaning effect while ensuring safety.

[0036] Continue to combine Figure 1-6 , Figure 10-12 As shown, in the present invention, the specific shape of the first box body 111 is not specifically limited. For example, in one embodiment, the first box body 111 has a top plate 111a and a bottom plate 111b arranged in parallel, and two end walls 111c are connected between the top plate 111a and the bottom plate 111b, and the shape of other side walls between the two end walls 111c is not limited. After installation, the first box body 111 is wrapped around the driving roller 210, so that the conveyor belt 220 turned around the driving roller 210 extends out from the opening 1111.

[0037] Continue to combine Figure 1-6 , Figure 10-12 As shown, in one embodiment of the present invention, the upper end and the lower end of the side where the opening 1111 of the first box body 111 are located are respectively provided with an inclined first mounting plate 1112 and a second mounting plate 1113. Specifically, the first mounting plate 1112 is connected to the top plate 111a and is inclined downward relative to the top plate 111a, as shown in FIG. Figure 3 As shown, a second mounting plate 1113 is provided at the lower end of the opening 1111 of the first box body 111. The second mounting plate 1113 is connected to the two end walls 111c and tilted upward, specifically, tilted upward in a direction away from the interior of the first box body 111, as shown in FIG. Figure 3 The first baffle 112a is movably connected to the first mounting plate 1112, and the gap between the first baffle 112a and the upper conveying surface of the conveyor belt 220 is adjusted by moving the first baffle 112a along the first mounting plate 1112, as shown in FIG. Figure 2-3 The second baffle 112b is movably connected to the second mounting plate 1113, and the gap between the second baffle 112b and the lower conveying surface of the conveyor belt 220 is adjusted by moving the second baffle 112b along the second mounting plate 1113, as shown in FIG. Figure 2-3 By moving the first baffle 112a and the second baffle 112b, the magnitude of the negative pressure adsorption force is adjusted, thereby achieving the adjustment of the cleaning effect.

[0038] Combination Figure 3-4 As shown, the first mounting plate 1112 and the second mounting plate 1113 are each provided with a plurality of connection holes 1114, and the number of the connection holes 1114 is not specifically limited. The first baffle plate 112a and the second baffle plate 112b are respectively connected to the connection holes 1114 through connecting members, and the first baffle plate 112a and the second baffle plate 112b can slide along the connecting members. In one embodiment, the connecting members are screws, and the first baffle plate 112a and the second baffle plate 112b are respectively connected to the first mounting plate 1112 and the second mounting plate 1113 through screws, which makes installation more convenient. Of course, other connecting members can also be selected.

[0039] Furthermore, a plurality of elongated holes 1121 are provided on the first baffle 112a and the second baffle 112b, and the elongated holes 1121 are arranged along the axial direction perpendicular to the first baffle 112a and the second baffle 112b, and the spacing between adjacent elongated holes 1121 corresponds to the spacing between adjacent connecting holes 1114. The connecting member is inserted into the elongated holes 1121 and the connecting hole 1114 to realize the installation of the first baffle 112a and the second baffle 112b, and the first baffle 112a and the second baffle 112b can adjust their positions by sliding along the elongated holes 1121. It is understandable that the first baffle 112a and the second baffle 112b are not limited to the aforementioned sliding connection mode, and it is also feasible to realize their sliding connection through other structures.

[0040] Continue to combine Figure 1-3 , Figure 10-11 As shown, in one embodiment of the present invention, arc-shaped slots 1115 are also formed on the two end walls 111c of the first box body 111. The arc-shaped slots 1115 are formed to be recessed toward the other side away from the opening 1111, and the arc-shaped slots 1115 are preferably arc-shaped and correspond to the outer diameter of the rotating shaft 211 of the driving roller 210. After installation, the first box body 111 is arranged along the axial direction of the driving roller 210, and the arc-shaped slots 1115 on the two end walls 111c are clamped at the two ends of the rotating shaft 211 of the driving roller 210, as shown in FIG. Figure 1 , Fig.10 As shown. Thus, a part of the driving roller 210 is accommodated in the cavity of the first box body 111, while the two ends of the rotating shaft 211 of the driving roller 210 protrude out of the two end walls 111c of the first box body 111, so that the first box body 111 is closer to the driving roller 210 after being wrapped outside the driving roller 210, thereby making the adsorption force on the conveyor belt 220 outside the driving roller 210 greater, so as to improve the cleaning effect.

[0041] It is understandable that the installation is not limited to the above-mentioned installation method. Even if both ends of the rotating shaft 211 of the driving roller 210 are accommodated in the interior of the first box body 111, cleaning can still be achieved.

[0042] Recombination Figure 1-Figure 13 As shown, in a more preferred embodiment of the present utility model, the contactless copper foil conveyor belt cleaning device 100 further includes a negative pressure take-over unit 120. The negative pressure take-over unit 120 includes a second box body 121 with a hollow structure and a connecting pipe 122 connected to the second box body 121, the second box body 121 is sealedly connected to the first box body 111 and the interiors of the two are connected, the other end of the connecting pipe 122 is connected to the negative pressure generator, and the side of the second box body 121 connected to the connecting pipe 122 is a special-shaped structure, and the setting of the special-shaped structure makes the negative pressure in the second box body 121 and the first box body 111 more uniform, and then makes the adsorption force more uniform, so as to improve the cleaning effect.

[0043] More specifically, a first mounting port 1116 is provided at the bottom of the first box body 111 or at a side away from the opening 1111, and a second mounting port 1211 corresponding to the first mounting port 1116 is provided on the second box body 121. The second mounting port 1211 of the second box body 121 is docked with the first mounting port 1116 of the first box body 111 to achieve internal communication between the two, and the second box body 121 and the first box body 111 are sealedly connected, for example, they are welded and fixed, but are not limited to this connection method.

[0044] See below Figure 8 As shown, in this embodiment, a plurality of protrusions 1212 are provided on one side of the second housing 121 away from the second mounting opening 1211 thereof, the protrusions 1212 protrude in a direction away from the second mounting opening 1211, and the connecting pipe 122 is connected to the protrusions 1212. When the second housing 121 and the first housing 111 are connected, the protrusions 1212 protrude in a direction away from the first housing 111, and the arrangement of the protrusions 1212 can make the negative pressure in the second housing 121 more uniform, thereby making the adsorption force in the first housing 111 more uniform and achieving a better cleaning effect.

[0045] Combine the following Figure 1-3 , Figure 7 As shown, in one embodiment of the utility model, the first installation port 1116 of the first box body 111 is provided on the bottom plate 111b thereof, and the bottom plate 111b is also provided with a plurality of connection holes. Correspondingly, the second installation port 1211 is provided on the bottom plate (not numbered) of the second box body 121, and the bottom plate is also provided with connection holes. During installation, the bottom plate of the second box body 121 is docked with the bottom plate 111b of the first box body 111 and the two are sealed and connected through the connection holes. At this time, the protrusion 1212 protrudes downward, and the connecting pipe 122 is connected to the side of the protrusion 1212, that is, it is connected to the side wall of the second box body 121 and protrudes to the side, as shown in FIG. Figure 1-2 shown.

[0046] Combine the following Figure 10-11 As shown, in another embodiment of the present invention, the first installation opening 1116 of the first box body 111 is opened on the side wall 111d away from the opening 1111, and the bottom plate 111b of the first box body 111 seals the bottom accordingly. Therefore, the first installation opening 1116 and the opening 1111 are located on opposite sides of the first box body 111, as shown in FIG. Fig.11 When the second box 121 is installed, compared with Figure 1 The second box body 121 is installed by rotating 90° in the manner described above, that is, the bottom plate of the second box body 121 is butted against the side wall 111d of the first box body 111 and sealed therewith, at which time, the protrusion 1212 protrudes away from the side of the first box body 111, and the connecting pipe 122 is connected to the side of the protrusion 1212 and protrudes downward, as shown in FIG. Fig.10 shown.

[0047] Combine again Figure 1-Figure 13 As shown, the working principle of the non-contact copper foil conveyor belt cleaning device 100 of the present invention is described.

[0048] Combination Figure 1 , Fig.10 As shown, when the copper foil suction rack releases the copper foil onto the conveyor belt 220 for transportation, impurities such as copper powder, copper scraps, and copper wire on the copper foil will adhere to the conveyor belt 220 , causing pollution to the conveyor belt 220 .

[0049] When the contactless copper foil conveyor belt cleaning device 100 is working, the negative pressure generator operates to form a negative pressure chamber in the first box 111, thereby adsorbing the conveyor belt 220 bypassing the driving roller 210. Since the conveyor belt 220 is a porous surface, the conveyor belt 220 is attached to the conveyor belt 220 at the turning position where the conveyor belt 220 bypasses the driving roller 210, thereby overcoming the influence of the holes on the conveyor belt 220 on the negative pressure. Therefore, the first box 111 is installed on one side of the driving roller 210 and wrapped around the outside thereof to adsorb the conveyor belt 220 at this position. The adsorption force at this position is the largest, and the impurities such as copper powder, copper scraps, and copper wire on the conveyor belt 220 can be absorbed to the greatest extent, and the cleaning effect is greatly improved; and compared with the prior art method of cleaning by adhesion through a sticky roller, the utility model can adsorb impurities on the conveyor belt 220 without contact, which can not only improve the cleaning effect, but also does not require regular manual operation, thereby reducing labor costs.

[0050] In the present invention, the gap between the first baffle 112a and the second baffle 112b and the conveyor belt 220 can be adjusted as needed by moving the positions of the first baffle 112a and the second baffle 112b. According to the requirements of production safety and cleaning effect, the gap should not be too large or too small, because the smaller the gap, the greater the negative pressure adsorption force and the better the cleaning effect. On the contrary, the larger the gap, the higher the safety. Therefore, the gap can be adjusted according to production needs to achieve the adjustment of the cleaning effect while ensuring safety.

[0051] Furthermore, the arrangement of the negative pressure taking over unit 120 and the second box body 121 with an anisotropic structure makes the negative pressure in the second box body 121 and the first box body 111 more uniform, thereby making the adsorption force more uniform, thereby producing a more uniform adsorption on the entire conveyor belt 220, thereby improving the cleaning effect.

[0052] To summarize, since the contactless copper foil conveyor belt cleaning device 100 of the utility model is provided with a negative pressure adsorption unit 110, the negative pressure adsorption unit 110 includes a first box body 111 and a baffle 112. The first box body 111 is a hollow structure and one side thereof is provided with an opening 1111. The baffle 112 is provided at the upper end or / and the lower end of the side where the opening 1111 of the first box body 111 is located. The baffle 112 is inclined and movably connected to the first box body 111. First, the negative pressure adsorption unit 110 is installed corresponding to the driving roller 210 of the copper foil conveyor belt 220, and the first box body 111 is wrapped outside the driving roller 210. Therefore, the negative pressure generator provides negative pressure power to form a negative pressure cavity inside the first box body 111, thereby adsorbing impurities such as copper powder, copper chips, and copper wire on the conveyor belt 220. When the conveyor belt 220 turns, it adheres to the driving roller 210 and is located in the negative pressure cavity to be adsorbed, thereby reducing the influence of the porous surface of the conveyor belt 220 on the negative pressure. This position has an effect on the conveyor belt 220. The adsorption force generated by 20 is the largest, thereby significantly improving the adsorption effect, thereby improving the cleaning effect of the conveyor belt 220; secondly, the baffles 112 are respectively located above or / and below the conveyor belt 220 wound on the driving roller 210, and the gap between the baffle 112 and the conveyor belt 220 is adjusted by moving the baffle 112, thereby adjusting the size of the negative pressure adsorption force, thereby achieving the adjustment of the cleaning effect; furthermore, the cleaning device 100 realizes online real-time cleaning of the conveyor belt 220, thereby improving the cleaning effect and cleaning efficiency.

[0053] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
