Description

Technical Field

[0001] This application relates to the field of laser imaging, and in particular to a device for determining the precise positioning of a mesh frame. Background Technology

[0002] visit Figure 1 In the field of laser imaging, the frame 10 is the most important carrier of the photosensitive coating. A uniformly coated photosensitive coating 11 is spread across one side of the frame 10. The laser (not shown) of the laser imaging device emits light, exposing the photosensitive coating 11 and transferring the image stored in the laser imaging device onto the photosensitive coating 11. Before exposure, the frame 10 needs to be vertically clamped onto the upper horizontal beam 21 and the lower horizontal beam 22 using four clamping units 31, 32, 33, and 34. However, while this clamping method with four sets of units 31, 32, 33, and 34 can hold the frame, the accurate positioning of the frame can only be judged by feel, not by direct observation. Summary of the Invention

[0003] This application provides a device for determining the precise placement of a wire frame, which aims to address the problem in the prior art that it is impossible to accurately determine whether the wire frame has been accurately placed in a preset position.

[0004] The solution of the present invention is as follows:

[0005] A device for determining the precise placement of a wire mesh frame includes: an upper crossbeam, a lower crossbeam, and a plurality of clamping units; the plurality of clamping units are respectively disposed on the upper and lower crossbeams for clamping the upper and lower edges of the wire mesh frame; characterized in that it further includes a first light display component and a second light display component, the first light display component being disposed at the right edge of the wire mesh frame, and the second light display component being disposed at the lower edge or the right edge of the wire mesh frame; the first light display component and the second light display component are used to determine that the wire mesh frame has been precisely placed at a preset position.

[0006] Furthermore, the first light display component includes: a first support plate, a first positioning block, and a first light display assembly;

[0007] The first support plate is vertically installed at the lower right end of the upper crossbeam. The first light display component and the first positioning block are arranged side by side on the left side of the first support plate. The first light display component is provided with a first power supply, a first wire, a first indicator light and two first metal contacts. The two first metal contacts and the left side of the first positioning block are on the same vertical plane.

[0008] In the first scenario, when the second light display component is located at the bottom edge of the frame:

[0009] The second light display component includes: a second positioning block and a second light display assembly; the second positioning block and the second light display assembly are arranged side by side on the upper end face of the lower crossbeam; the second light display assembly is provided with a second power supply, a second wire, a second indicator light and two second metal contacts; the two second metal contacts and the upper end face of the second positioning block are on the same horizontal plane;

[0010] The movable frame is positioned such that the right side of the right frame abuts against the first positioning block and two first metal contacts, and the lower edge of the bottom frame abuts against the upper edge of the second positioning block and two second metal contacts. After the two first metal contacts make contact with the right side of the right frame, the first indicator light illuminates. After the two second metal contacts make contact with the lower edge of the bottom frame, the second indicator light illuminates. By observing that both the first and second indicator lights are illuminated, it is confirmed that the frame has achieved precise vertical and horizontal positioning at the preset position.

[0011] In the second scenario, the second light display component is positioned on the right side of the frame and is arranged side-by-side with the first light display component:

[0012] The second light display component includes: a second positioning block and a second light display assembly; the second light display assembly is located directly below the first light display assembly, the second positioning block is located on the lower end face of the lower frame and is distributed perpendicular to the second light display assembly; the two first metal contacts, the left side of the first positioning block and the two second metal contacts are on the same vertical plane;

[0013] The movable frame is positioned such that the right side of the right frame abuts against the left side of the first positioning block, the two first metal contacts, and the two second metal contacts; the lower end of the lower frame abuts against the upper end of the second positioning block; the two first metal contacts and the two second metal contacts make contact with the right side of the right frame of the frame, and the first and second indicator lights illuminate to indicate that the frame has achieved precise positioning in both the vertical and horizontal directions.

[0014] Furthermore, the first light display component and the second light display component have the same structure: both first metal contacts are exposed outside the insulating shell of the first light display component, and both second metal contacts are exposed outside the insulating shell of the second light display component; the first power supply is built into the first cavity of the first light display component formed by the insulating shell; and the second power supply is built into the second cavity of the second light display component formed by the insulating shell.

[0015] Furthermore, both the first and second indicator lights emitted green light.

[0016] Furthermore, each clamping unit includes a cylinder and a clamp, with each clamp holding the two end faces of the mesh frame along the thickness direction.

[0017] Furthermore, each clamping unit is a thumb cylinder.

[0018] This application also discloses a method for determining the precise placement of a wireframe using the aforementioned device, including:

[0019] Step 1: Release several clamping units of the device and feed the wire mesh frame in from the left side, such that: the right side of the right frame of the wire mesh frame abuts against the left side of the first positioning block and the two first metal contacts of the first light display component; the lower end of the lower frame of the wire mesh frame abuts against the upper end of the second positioning block and the two second metal contacts of the second light display component; or, the right side of the right frame of the wire mesh frame abuts against the left side of the first positioning block, the two first metal contacts of the first light display module and the two second metal contacts of the second light display module; the lower end of the lower frame of the wire mesh frame abuts against the second positioning block.

[0020] Step 2: By observing that both the first and second indicator lights are lit, it can be determined that the frame has achieved precise positioning in the preset vertical and horizontal directions;

[0021] Step 3: Control several clamping units to clamp the wire frame.

[0022] Furthermore, prior to step 1, the following steps are also included:

[0023] The two first metal contacts are positioned on the same vertical plane as the left side of the first positioning block, and the two second metal contacts are positioned on the same horizontal plane as the upper end face of the second positioning block; or,

[0024] The two first metal contacts, the left side of the first positioning block, and the two second metal contacts are placed on the same vertical plane.

[0025] The technical effects that this equipment and method can achieve are:

[0026] In the first scenario: When the mesh frame is fed in from the left, the right side of the right frame of the mesh frame abuts against the left side of the first positioning block and the two first metal contacts of the first light display component. The lower end of the bottom frame of the mesh frame abuts against the upper end of the second positioning block and the two second metal contacts of the second display module. Since the two first metal contacts and the left side of the first positioning block are on the same vertical plane, when the right side of the right frame of the mesh frame abuts against the left side of the first positioning block, it will also abut against the two first metal contacts simultaneously. The two first metal contacts are connected through the right side of the right frame of the mesh frame, and the circuit in the first light display component is connected, causing the first indicator lights to illuminate. Similarly, since the two second metal contacts and the upper end of the second positioning block are on the same horizontal plane, when the lower end of the bottom frame of the mesh frame abuts against the upper end of the second positioning block, it will also abut against the two second metal contacts simultaneously. The two second metal contacts are connected through the lower end of the bottom frame of the mesh frame, and the circuit in the second light display component is connected, causing the second indicator lights to illuminate. By observing that both the first and second indicator lights are lit, the preset positions of the frame in the horizontal and vertical directions can be determined intuitively, thus achieving precise positioning.

[0027] The second scenario: When the mesh frame is fed in from the side, the right side of the right frame and the bottom edge of the bottom frame of the mesh frame respectively touch the first positioning block and the second positioning block. Since the two first metal contacts of the first light display module, the two second metal contacts of the second light display module, and the left side of the first positioning block are all on the same vertical plane, when the right side of the right frame of the mesh frame touches the left side of the first positioning block, it will also inevitably touch the two first metal contacts and the two second metal contacts, causing both the first and second indicator lights to illuminate. By observing that both the first and second indicator lights are illuminated, it can be determined that the mesh frame has achieved precise positioning at the preset position.

[0038] This application discloses a device for determining the precise placement of a wire mesh frame, comprising: an upper crossbeam, a lower crossbeam, and a plurality of clamping units; the plurality of clamping units are respectively disposed on the upper crossbeam and the lower crossbeam for clamping the upper and lower edges of the wire mesh frame; the device further comprises a first light display component and a second light display component, the first light display component being disposed at the right edge of the wire mesh frame, and the second light display component being disposed at the lower edge or the right edge of the wire mesh frame; the first light display component and the second light display component are used to determine that the wire mesh frame has been precisely placed at a preset position.

[0039] The above-mentioned device will be described in detail below with reference to two embodiments.

[0040] Example 1

[0041] refer to Figure 2 This application discloses a device 00 for determining the precise positioning of a wire mesh frame, comprising an upper crossbeam 21, a lower crossbeam 22, and a plurality of clamping units 31, 32, 33, and 34 (this application exemplarily discloses four clamping units). The four clamping units are respectively used to clamp the upper frame 101 and the lower frame 102 of the wire mesh frame 10, fixing the wire mesh frame 10 to the upper crossbeam 21 and the lower crossbeam 22.

[0042] Compared to existing technologies, reference Figure 6 and Figure 7 The device 00 also includes: a first light display component 40A and a second light display component 50A; the first light display component 40A includes: a first support plate 41, a first positioning block 42 and a first light display assembly 40; the second light display component 50A includes: a second positioning block 52 and a second light display assembly 50;

[0043] The first support plate 41 is disposed at the lower end of the right side of the upper crossbeam 21, the first light display component 40 and the first positioning block 42 are disposed side by side on the left side of the first support plate 41, and the first positioning block 42 is located below the first display module 40.

[0044] The second positioning block 52 and the second light display component 50 are arranged side by side on the upper end face of the lower crossbeam 22, and the second positioning block 52 is located to the right of the second light display component 50.

[0045] In this application, the first lighting display component 40 includes a first power supply 401, a first indicator light 402, a first wire 403, and two first metal contacts 404 and 405. The second lighting display component 50 includes a second power supply 501, a second indicator light 502, a second wire 503, and two second metal contacts 504 and 505. It should be noted that the first power supply 401 and the second power supply 501 can be the same or different; the first indicator light 402 and the second indicator light 502 can be the same or different. The two first metal contacts 404 and 405 and the two second metal contacts 504 and 505 are identical. In the first lighting display component 40, the first metal contacts 404, the first power supply 401, the first indicator light 402, and the first metal contacts 405 are connected in series via the first wire 403, but the two first metal contacts 404 and 405 do not contact each other and are insulated from each other by the insulating shell 406 of the first lighting display component 40. The left side 421 of the two first metal contacts 404 and 405 and the first positioning block 42 needs to be set to be on the same vertical plane.

[0046] In the second light display assembly 50, the second metal contact 504, the second power supply 501, the second indicator light 502, and the second metal contact 505 are connected in series via the second wire 503. The two second metal contacts 504 and 505 do not contact each other and are insulated from each other by the insulating shell 506 of the second light display assembly 50. The two second metal contacts 504 and 505 and the upper end surface 521 of the second positioning block 52 need to be set on the same horizontal plane.

[0047] When installing the wire frame 10, first loosen the four clamping units 31, 32, 33 and 34, and push the wire frame 10 from left to right so that the right side 1031 of the right frame 103 of the wire frame 10 contacts the two first metal contacts 404 and 405 and the left side 421 of the first positioning block 42, and the lower end 1021 of the lower frame 102 of the wire frame 10 abuts against the upper end 521 of the second positioning block 52 and the two second metal contacts 504 and 505. Since all the edges of the frame 10 are made of metal, when the right side 1031 of the right side frame 103 of the frame 10 contacts the two first metal contacts 404 and 405, the two first metal contacts 404 and 405 are connected through the right side 1031 of the right side frame 103. The first metal contact 404, the first wire 403, the first power supply 401, the first indicator light 402 and the first metal contact 405 form a closed circuit, and the first indicator light 402 lights up.

[0048] The two second metal contacts 504 and 505 are connected through the lower end face 1021 of the lower frame 102 of the mesh frame 10, so that the second metal contact 504, the second power supply 501, the second indicator light 502, the second metal contact 505 and the second wire 503 in the second light display assembly 50 form a closed circuit, and the second indicator light 502 lights up.

[0049] It is understandable that by observing that the first indicator light 402 and the second indicator light 502 are lit, it can be intuitively determined that the mesh frame 10 has achieved positioning on the first positioning block 42 and the second positioning block 52, that is, the mesh frame 10 has achieved accurate positioning at the preset position in both the vertical and horizontal directions.

[0050] Once the mesh frame 10 is accurately positioned, clamping forces are applied to the four clamping units 31, 32, 33 and 34 to fix the mesh frame 10 to the upper crossbeam 21 and the lower crossbeam 22.

[0051] In addition, in this embodiment, the first light display component 40 and the second light display component 50 have the same structure. Two first metal contacts 404 and 405 are exposed outside the insulating shell of the first light display component 40, and two second metal contacts 504 and 505 are exposed outside the insulating shell of the second light display component 50. The first power supply 401 is built into the first cavity of the first light display component 40 formed by the insulating shell; the second power supply 501 is built into the second cavity of the second light display component 50 formed by the insulating shell.

[0052] The light emitted by the first indicator light 402 and the second indicator light 502 must be visible to the operator.

[0053] In this embodiment, the line connecting the two first metal contacts 404 and 405 is perpendicular to, horizontal to, or intersects the horizontal plane. This can be understood as the two first metal contacts 404 and 405 being vertically, horizontally, or inclined relative to the horizontal plane, as long as the two first metal contacts 404 and 405 are on the same vertical plane as the left side 421 of the first positioning block 42. The line connecting the two second metal contacts 504 and 505 is perpendicular to, parallel to, or intersects the horizontal plane. This can be understood as the two second metal contacts 504 and 505 being vertically, parallel to, or inclined relative to the vertical plane.

[0054] Furthermore, the indicator lights on each lighting module preferably emit green light, as green typically indicates normal operation. However, the indicator lights can also emit yellow, purple, or other colors, but these colors are less commonly used.

[0055] In this embodiment, each clamping unit may include, for example, a cylinder or a clamp, wherein the cylinder is used to control the clamp to hold the two end faces of the mesh frame along the thickness direction. The connection method, working principle, and working process of the cylinder and the clamp are prior art and will not be described in detail here. Alternatively, the clamping unit may also be a thumb cylinder (pneumatic finger), that is, the cylinder and the clamp are designed as one unit.

[0056] The advantage of the device for determining the precise positioning of the wire mesh frame described in this embodiment is that when the wire mesh frame is advanced horizontally from the left, the right side of the wire mesh frame abuts against the first positioning block in the vertical direction, and the lower side abuts against the second positioning block in the horizontal direction. Both the first indicator light in the vertical direction and the second indicator light in the horizontal direction are turned on and illuminated, indicating that the wire mesh frame has achieved accurate positioning in the preset horizontal and vertical directions. This provides a more intuitive judgment for the accurate positioning of the wire mesh frame.

[0057] Example 2

[0058] refer to Figure 3 and Figure 4This embodiment discloses a device 00A for determining the precise positioning of a wire mesh frame, including an upper crossbeam 21, a lower crossbeam 22, and several clamping units 31, 32, 33, and 34 (this application exemplarily discloses four sets of clamping units). The four clamping units respectively clamp the upper frame 101 and the lower frame 102 of the wire mesh frame 10, fixing the wire mesh frame 10 to the upper crossbeam 21 and the lower crossbeam 22.

[0059] The improvement over the prior art is that this device 00A further includes: a first light display component 40A and a second light display component 50A; the first light display component 40A and the second light display component 50A are arranged side by side on the right side frame of the mesh frame 10. The first light display component 40A includes: a first vertical plate 41, a first positioning block 42, and a first light display module 40; the second light display component 50A includes: a second vertical plate 51, a second positioning block 52, and a second light display module 50. Compared with Embodiment 1, in Embodiment 2, the structure and placement of the second light display component 50A are different (see reference). Figure 3 , Figure 4 and Figure 8 ).

[0060] refer to Figure 3 and Figure 6 In the first light display component 40A, the first vertical plate 41 is located at the lower end of the right side of the upper crossbeam 21, the first light display module 40 is detachably installed on the side of the first vertical plate 41 near the mesh frame 10, and the first positioning block 42 is installed on the first vertical plate 41 and located below the first display module 40.

[0061] refer to Figure 3 , Figure 4 and Figure 8 In the second light display component 50A, the second positioning block 52 abuts against the lower crossbeam 22 and the lower edge frame 102 of the mesh frame. The second vertical plate 51 is set on the upper end face of the right side of the second positioning block 52. The second light display module 50 is installed on the second vertical plate 51 and is on the same vertical plane as the first light display module 40.

[0062] In this embodiment, the first light display module 40 is exactly the same as in Embodiment 1, including: a first power supply 401, a first indicator light 402, a first wire 403, and two first metal contacts 404 and 405. The second light display module 50 includes a second power supply 501, a second indicator light 502, a second wire 503, and two second metal contacts 504 and 505. It should be noted that the first power supply 401 and the second power supply 501 can be the same or different; the first indicator light 402 and the second indicator light 502 can be the same or different. The two first metal contacts 404 and 405 and the two second metal contacts 504 and 505 are all the same. In the first light display module 40, the first metal contacts 404, the first power supply 401, the first indicator light 402, and the first metal contacts 405 are connected in series through the first wire 403, but the first metal contacts 404 and 405 do not contact each other and are insulated from each other by the insulating shell 406 of the first light display module 40. In the second light display module 50, the second metal contact 504, the second power supply 501, the second indicator light 502, and the second metal contact 505 are connected in series via the second wire 503. The second metal contact 504 and the second metal contact 505 do not contact each other and are insulated from each other by the insulating shell 506 of the second light display module 50.

[0063] When installing the wire frame 10, first loosen the four clamping units 31, 32, 33 and 34, and push the wire frame 10 from left to right so that the right side 1031 of the right frame 103 of the wire frame 10 contacts the two first metal contacts 404, 405, the two second metal contacts 504, 505 and the left side 421 of the first positioning block 42. At the same time, the lower end of the lower frame 102 of the wire frame 10 abuts against the upper end of the second positioning block 52. Since the frame of the mesh frame 10 is made of metal, when the right side 1031 of the right frame 103 of the mesh frame 10 comes into contact with the two first metal contacts 404 and 405, the two second metal contacts 504 and 505, and the left side 421 of the first positioning block 42, the first metal contacts 404 and 405 are connected through the right side 1031 of the right frame 103. The first metal contacts 404, the first wire 403, the first power supply 401, the first indicator light 402 and the first metal contacts 405 form a closed circuit, and the first indicator light 402 lights up. Since the left sides of the two first metal contacts 404 and 405 and the two second metal contacts 504 and 505 are on the same vertical plane as the left side 421 of the first positioning block 42, when the right side 1031 of the right frame 103 of the mesh frame 10 just touches the first metal contacts 404 and 405, it means that the right side 1031 of the right frame 103 of the mesh frame 10 just touches the left side 421 of the first positioning block 42. Therefore, when the first indicator light 402 is lit, it means that the right side 1031 of the right frame 103 of the mesh frame 10 just touches the left side 421 of the first positioning block 42.

[0064] Similarly, since the second metal contacts 504 and 505 simultaneously contact the right side of the right side frame 103 of the mesh frame 10, the second metal contact 504, the second power supply 501, the second indicator light 502, the second metal contact 505, and the second wire 503 in the second light display module 50 are connected and form a closed loop. The second indicator light 502 lights up, and the lower frame 102 of the mesh frame 10 abuts against the upper surface of the second positioning block 52. Therefore, the right side and lower surface of the mesh frame 10 are positioned on the first positioning block 42 and the second positioning block 52, respectively, thus achieving positioning in the vertical and horizontal directions. Finally, clamping forces are applied to the four clamping units 31, 32, 33, and 34 to fix the mesh frame 10.

[0065] In this embodiment, the light emitted by the first and second indicator lights is preferably green, because green usually indicates normal operation. However, the light emitted by the two indicator lights can also be yellow, purple, or other colors, but indicator lights with such colors are less commonly used.

[0066] In this embodiment, each clamping unit may include, for example, a cylinder or a clamp, wherein the cylinder is used to control the clamp to hold the two end faces of the mesh frame along the thickness direction. The connection method, working principle, and working process of the cylinder and the clamp are prior art and will not be described in detail here. Alternatively, each clamping unit may also be a thumb cylinder (pneumatic finger), that is, the cylinder and the clamp are designed as one unit.

[0067] The advantage of the device for determining the precise positioning of the wire mesh frame described in this embodiment is that when the wire mesh frame is pushed horizontally from the left, the right side frame of the wire mesh frame abuts against the first positioning block in the vertical direction, and the lower side frame abuts against the second positioning block set in the horizontal direction. The first indicator light and the second indicator light set in the vertical direction emit light, indicating that the wire mesh frame is accurately positioned in the preset direction. This provides a more intuitive judgment for the accurate positioning of the wire mesh frame.

[0068] refer to Figure 5 This application also discloses a method for determining the precise placement of a wire frame using the aforementioned device, characterized by comprising:

[0069] Step 1: Release several clamping units of the device and feed the wire mesh frame in from the left side, such that: the right side of the right frame of the wire mesh frame abuts against the left side of the first positioning block and the two first metal contacts of the first light display component; the lower end of the lower frame of the wire mesh frame abuts against the upper end of the second positioning block and the two second metal contacts of the second light display component; or, the right side of the right frame of the wire mesh frame abuts against the left side of the first positioning block, the two first metal contacts of the first light display module and the two second metal contacts of the second light display module; the lower end of the lower frame of the wire mesh frame abuts against the second positioning block.

[0070] Step 2: By observing that both the first and second indicator lights are lit, it can be determined that the frame has achieved precise positioning in the preset vertical and horizontal directions;

[0071] Step 3: Control several clamping units to clamp the wire frame.

[0072] Further: Before step 1, the method further includes setting the two first metal contacts and the left side surface of the first positioning block on the same vertical plane, and setting the two second metal contacts and the upper end surface of the second positioning block on the same horizontal plane; or,

[0073] The two first metal contacts, the left side of the first positioning block, and the two second metal contacts are placed on the same vertical plane.

[0074] The specific details of steps 1 to 3 above have been described in detail when introducing the equipment, and will not be repeated here.
