Description

Technical Field

[0001] The utility model relates to a wiping device, in particular to a wiping device suitable for wiping a liquid material coating device in a liquid material coating equipment. Background Art

[0002] In the production process of electronic products, liquid material coating operations are often required. The liquid material coating operation is usually implemented through a liquid material coating device in a liquid material coating equipment. The liquid material coating equipment and liquid material coating device can be exemplified by Taiwan Patent No. M632843U "Coating Equipment", No. I767470B "Liquid Material Extrusion Device and Equipment Using Liquid Material Extrusion Device"... etc. However, as the number of liquid material coating operations increases, it is inevitable that residual liquid will remain at a liquid outlet of the liquid material coating device, thereby affecting subsequent liquid material coating operations, resulting in a decrease in liquid material coating efficiency or liquid material coating accuracy. At this time, it is usually necessary to clean the liquid material coating device through a wiping device in the liquid material coating equipment.

[0003] The wiping device usually includes a supply wheel and a take-up wheel axially arranged on the same vertical wall, and a wiping tape wound on the supply wheel. The take-up wheel can rotate to pull the wiping tape out of the supply wheel and reel it on the take-up wheel. The liquid material coating device can be moved above the wiping device to contact the wiping tape with the liquid outlet. The wiping tape that is continuously transported can be used to wipe the residual liquid at the liquid outlet to wipe off the residual liquid. This existing wiping device is usually embedded in a machine wall of the liquid material coating equipment. In addition, the supply wheel and the take-up wheel are both arranged on the same vertical wall of the machine wall. When repairing or replacing the wiping tape, the operator often needs to bend over or put his hand into an area that is blocked by the machine and difficult to see with the naked eye. Therefore, the operation is relatively inconvenient, or it can be said that the operation changes are less and needs to be improved. Utility Model Content

[0004] The purpose of the present invention is to improve at least one disadvantage of the prior art.

[0005] The wiping device of the utility model is suitable for use with a wiping belt and comprises a supporting unit and a conveying unit.

[0006] The support unit is provided with a bracket group and a support seat group pivotally connected to the bracket group and capable of swinging relative to the bracket group. The conveying unit is arranged on the support seat group and is provided with a first pulley and a second pulley suitable for cooperating to convey the wiping tape. The conveying unit can be driven by the support seat group to switch between a first state and a second state. In the first state, the axial direction of the first pulley and the second pulley is in the same direction as a first direction. In the second state, the axial direction of the first pulley and the second pulley is in the same direction as a second direction. The second direction intersects the first direction.

[0007] The beneficial effect of the utility model is that the conveying unit can be driven by the support assembly to change between the first state and the second state, and because there are more different state changes, it can bring convenience in operation and maintenance.

[0055] See also Figure 1 , 2 3. An embodiment of the wiping device of the utility model is suitable for use with a wiping belt 91 (see Figure 3 , and can be used as a supplementary reference Figure 5 ) to wipe a liquid coating head (not shown) of a liquid coating device (not shown). The wiping belt 91 is, for example, a belt body made of fiber material, but is not limited thereto, and can have different material variations depending on the type of liquid material.

[0056] The wiping device comprises a supporting unit 1 , and a conveying unit 2 , a wiping table unit 3 , a liquid spraying unit 4 , a sensing unit 5 and a metering unit 6 arranged on the supporting unit 1 .

[0057] See also Figure 2 , 3 4. The support unit 1 is provided with a bracket group 11 suitable for being arranged on a machine table 92, a support seat group 12 pivotally connected to the top end of the bracket group 11 and capable of pivoting relative to the bracket group 11, and two top support groups 13 pivotally connected between the bracket group 11 and the support seat group 12 and spaced laterally from each other.

[0058] The bracket assembly 11 is provided with two bracket members 111 suitable for being arranged on the machine table 92. Each bracket member 111 is L-shaped and is spaced apart from another bracket member 111 in a horizontal direction.

[0059] The support assembly 12 comprises a support plate 121 in the shape of a rectangle extending vertically, two support legs 122 extending backward from the left and right long sides of the support plate 121, a pivot block 123 extending in the left and right long directions and arranged at the top end of the rear side of the support plate 121, and a pivot shaft 124 inserted in the pivot block 123 and pivotally connected to the top end of the bracket member 111 (see FIG. Figure 4 ).

[0060] The supporting groups 13 are spaced apart from each other. Each supporting group 13 is provided with a pivot sleeve 131 pivotally connected to the bottom of one of the supporting members 111 of the supporting group 11, and a telescopic member 132 pivotally connected to one of the supporting legs 122 of the supporting group 12. Each telescopic member 132 is inserted into a respective one of the pivot sleeves 131, and can protrude from the pivot sleeve 131 or retract into the pivot sleeve 131, and can be positioned relative to the pivot sleeve 131 to maintain the overall length of the respective one of the supporting groups 13.

[0061] See also Figure 1 ,2 3. The conveying unit 2 is provided with a first pulley 21 and a second pulley 22 arranged at a vertical interval in the front side of the support plate 121, a plurality of guide rollers 23 arranged on the support plate 121, and a driver 24 arranged at the rear side of the support plate 121 (see Figure 2 ).

[0062] The first belt wheel 21 and the second belt wheel 22 are adapted to cooperate with each other along a conveying path R11 (see Figure 3 ) to transport the wiping tape 91. The transport path R11 is actually the extension and movement path of the wiping tape 91. Each of the first pulley 21 and the second pulley 22 is provided with a wheel shaft 25 (auxiliary reference 25) suitable for winding the wiping tape 91. Figure 5 ), and a stopper 26 located at the front end of the axle 25. Each of the stoppers 26 has a disc-like shape and is suitable for preventing the wiping belt 91 from escaping from a respective axle 25 in the axial direction.

[0063] The guide roller 23 is located on the conveying path R11 and is suitable for cooperating to tension the wiping belt 91 .

[0064] The driver 24 can drive the second pulley 22 to rotate, so as to pull the wiping belt 91 out of the first pulley 21 and reel it onto the second pulley 22. In other words, the first pulley 21 is a supply pulley, and the second pulley 22 is a take-up pulley.

[0065] The wiping table unit 3 is fixed to the top of the support plate 121 of the support assembly 12 and is located between the first belt pulley 21 and the second belt pulley 22 on the conveying path R11. The wiping table unit 3 is provided with a base 31 perpendicular to the support plate 121, two rollers 32 respectively arranged at the left and right opposite ends of the base 31, and a flexible pad 33 located on the base 31.

[0066] The base 31 is H-shaped, and its extension direction (length direction) is the same as the extension direction of the conveying path R11. The rollers 32 are spaced apart from each other along the conveying path R11, and can cooperate to tighten the wiping belt 91 on the wiping table unit 3. The pad 33 is used as Figure 3 The pad is shown between the base 31 and the wiping belt 91. The pad 33 is flexible and can provide a margin / space for deformation, thereby allowing the wiping belt 91 to be squeezed and deformed by the liquid material coating head, thereby protecting the liquid material coating head and having a larger contact area with the liquid material coating head, thereby improving cleaning efficiency.

[0067] The liquid spraying unit 4 is mounted on the bracket member 111 on the right side of the bracket assembly 11 and is located between the base 31 and the first pulley 21 in the moving direction of the wiping belt 91. The liquid spraying unit 4 is located beside the conveying path R11 and can be connected with a liquid infusion tube 93 to spray a cleaning liquid onto the wiping belt 91 before the wiping belt 91 moves to the base 31, so as to improve the cleaning efficiency of the wiping belt 91 for the liquid coating head.

[0068] The sensing unit 5 is mounted on the bracket member 111 on the left side of the bracket assembly 11. The sensing unit 5 is provided with a sensing member 51 located between the first pulley 21 and the second pulley 22 and beside the passage where the wiping belt 91 must pass. The sensing member 51 can project light forward toward the wiping belt 91 on the conveying path R11 and can receive light reflected by the wiping belt 91, thereby sensing whether the wiping belt 91 exists on the conveying path R11. The sensing member 51 is not limited to being located between the first pulley 21 and the second pulley 22, as long as it is located beside the passage where the wiping belt 91 must pass.

[0069] The metering unit 6 includes a passive roller 61 and a pressure wheel set 62 protruding from the front side of the support plate 121, and a sensor set 63 installed at the rear side of the support plate 121 and connected to the passive roller 61.

[0070] The front end of the passive roller 61 and the pressure wheel assembly 62 are suitable for Figure 3 The schematic diagram is shown on the opposite sides of the wiping belt 91. The rear end of the passive roller 61 is as shown in FIG. Figure 2 As shown, the support plate 121 protrudes backward to connect with the sensing group 63 .

[0071] The pressure wheel assembly 62 includes an L-shaped lever 621, a pivot 622 pivotally mounted at the turning point of the lever 621 on the support plate 121, a pressure wheel 623 mounted at one end of the lever 621, and an elastic member 624 mounted at the other end of the lever 621.

[0072] The elastic member 624 can provide elastic force to pull the lever 621, so that the pressing wheel 623 presses against the front end of the passive roller 61. In this way, when the wiping belt 91 moves along the conveying path R11, the passive roller 61 can be driven by the wiping belt 91 to rotate.

[0073] The sensing group 63 is provided with an encoding disk 631 installed at the rear end of the passive roller 61, and a sensor 632 capable of sensing and reading the encoding disk 631. The sensor 632 can sense the structure on the encoding disk 631 by light to read the information expressed in the form of the structure, and generate an electrical signal to be further used by a computer unit (not shown) to calculate the number of turns of the passive roller 61. Therefore, the computer unit can convert the number of turns of the passive roller 61 into the length of the wiping tape 91 rolling over the passive roller 61, thereby estimating the amount of use or the length of the remaining length of the wiping tape 91.

[0074] See also Figure 1 , 4 5, the support plate 121 of the support assembly 12 can be pivoted up and down relative to the support member 111 of the support assembly 11, and in a Figure 1 A first position extending vertically upward and downward as shown in Figure 5 The first belt pulley 21 and the second belt pulley 22 are driven to change between a first state and a second state.

[0075] In the first state, the axial directions of the first pulley 21 and the second pulley 22 are in the same direction as a first direction D11. The first direction D11 is parallel to the front-back direction of the machine table 92. At this time, the base 31 and the pad of the wiping table unit 3 face upward.

[0076] In the second state, the axial direction of the first pulley 21 and the second pulley 22 is in the same direction as a second direction D12. The second direction D12 is a vertical direction perpendicular to the machine table 92. Since the second direction D12 is a vertical direction and the first direction D11 is a front-back direction, the second direction D12 intersects the first direction D11 and the second direction D12 and the first direction D11 are perpendicular to each other. At the same time, the base 31 and the pad 33 of the wiping table unit 3 face backwards.

[0077] Since the support plate 121 of the wiping device can be pivoted between the first position and the second position, the first pulley 21 and the second pulley 22 can be switched between the first state and the second state. Figure 1 , 5 The two different use states shown in FIG. 1 , therefore, the wiping device has the characteristic of various use states. Figure 5In the state shown, the laterally extending support plate 121 facilitates the first pulley 21 and the second pulley 22 to be exposed outside the machine, so that the operator can grasp the positions of the first pulley 21 and the second pulley 22 with the naked eye. Therefore, the operator does not need to bend over or put his hand into the area that is difficult to see with the naked eye. Therefore, the wiping device also has the feature of being particularly conducive to the maintenance or replacement of the wiping belt 91.

[0078] In summary, the utility model of the wiping device has the following effect: the conveying unit 2 can be driven by the support assembly 12 to switch between the first state and the second state. Since there are more different state changes, it can bring convenience in operation and maintenance.

[0079] However, the above is only a preferred embodiment of the present utility model, and it cannot be used to limit the scope of implementation of the present utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the utility model description are still within the scope of the present utility model patent.
