Description

Technical Field

[0001] The present application relates to the technical field of PCB production equipment, and more specifically, to a maintenance device and method for a horizontal line roller. Background Art

[0002] In order to automate the production process of PCB boards, a large number of horizontal conveyor line production equipment are used in the existing production process of PCB boards. A large number of rollers are installed in the horizontal conveyor line. The rollers are used to carry and transport PCB boards. A transmission gear disc is installed on each roller, and the transmission gear disc is used to transmit power between the rollers. For example, Patent CN212023769U (Application No.: CN202020626979.4) provides a combined roller, including an upper roller and a lower roller arranged oppositely up and down; the upper roller includes a first rotating shaft, a first gear and an upper roller wheel, the first gear and the upper roller wheel are arranged on the first rotating shaft, the lower roller includes a second rotating shaft, a second gear and a lower roller wheel, the second gear and the lower roller wheel are arranged on the second rotating shaft, and the first gear and the second gear are engaged with each other.

[0003] In the prior art, due to the relatively complex external structure of the roller, it is inconvenient to maintain the roller. For example, when disassembling the first gear and the second gear on the upper roller and the lower roller, it is necessary to knock the first gear and the second gear on the upper roller and the lower roller so that the first gear and the second gear are separated from the roller. This disassembly method is likely to knock the first gear and the second gear out of shape and even damage the structure of the first gear and the second gear. Therefore, how to efficiently maintain the roller is of great significance. Summary of the Invention

The roller includes a rod body, a roller disc and a gear disc. The roller disc is arranged in the middle of the rod body, and the gear disc is arranged at the end of the rod body. The maintenance device includes a fixing component and an extrusion component. The fixing component is used to fix the roller, and the extrusion component is used to extrude the rod body from the end of the rod body to remove the gear disc from the rod body.

[0006] In a possible implementation, gear grooves for positioning the gear pieces are respectively provided at both ends of the fixing component. The gear grooves can position the gear pieces. The extrusion component includes two extrusion heads. Each extrusion head can reciprocate along the length direction of the rod body.

[0008] In another possible implementation, a plurality of base rod cavities for correcting the rod body are provided on the base, and a plurality of top seat rod cavities corresponding to the base rod cavities are provided on the top seat.

[0009] In another possible implementation, axial spaces for the roller pieces to move axially on the rod body are provided on the base cavities and the top seat cavities. Before the rod body and the gear piece are separated, there is a distance between the roller piece and the end of the axial space. After the rod body and the gear piece are separated, the roller piece and the end of the axial space can abut against each other.

[0010] In another possible implementation, the extrusion component further includes a force measuring component and a control component. The force measuring component is used to detect the rod extrusion force value of the extrusion head on the rod body.

[0011] The embodiment of the present application also provides a maintenance method for a horizontal line pulley. This method includes: fixing the pulley through the fixing component; extruding the rod body from the end of the rod body through the extrusion component to remove the gear piece from the rod body.

[0012] In another possible implementation, the method further includes: after placing the pulley on the base, the base and the top seat approach and abut against each other, correcting the roller pieces through the base cavities and the top seat cavities, and correcting the rod body through the cooperation of the base rod cavities and the top seat rod cavities; the base and the top seat separate from each other to generate a gap, and the gear piece is removed from the rod body by extruding the rod body from the end of the rod body through the extrusion head.

[0013] In another possible implementation, the gear piece is removed from the rod body by squeezing the rod body from the end of the rod body by a squeezing head, including: detecting the rod body squeezing force value of the squeezing head on the rod body, and when the rod body squeezing force value is less than or equal to a preset pressure value, controlling the squeezing head to continuously squeeze the rod body; when the rod body squeezing force value is greater than the preset pressure value, controlling the squeezing head to stop squeezing the rod body.

[0014] In another possible implementation, the method further includes: placing the gear piece to be installed in the gear slot, replacing the squeezing head on the side where the gear piece to be installed is located with a squeezing plate that supports the gear piece, and squeezing the rod body by the squeezing head on the opposite side of the gear piece to be installed, so that the rod body can be inserted into the shaft hole of the gear piece to be installed; wherein, the gear piece is provided with a guiding portion for guiding the rod body.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that when a component or structure is referred to as "fixed to" or "disposed on" another component or structure, it can be directly on the other component or structure or indirectly on the other component or structure. When a component or structure is referred to as "connected to" another component or structure, it can be directly connected to the other component or structure or indirectly connected to the other component or structure.

[0029] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or a component or structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0030] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0031] In the prior art, due to the relatively complex external structure of the line roller, it is inconvenient to maintain the line roller. For example, when disassembling the first gear and the second gear on the upper line roller and the lower line roller, it is necessary to strike the first gear and the second gear on the upper line roller and the lower line roller, so that the first gear and the second gear are disengaged from the line roller. This disassembly method easily deforms the first gear and the second gear when struck, and even damages the structures of the first gear and the second gear. Therefore, how to efficiently maintain the line roller is of great significance.

[0032] For the above reasons, the embodiments of this application provide a maintenance device for a horizontal line roller. The maintenance device is used to maintain the line roller. The line roller includes a rod body, a roller blade, and a gear blade. The roller blade is arranged in the middle of the rod body, and the gear blade is arranged at the end of the rod body. The maintenance device includes a fixing component and an extrusion component. The fixing component is used to fix the line roller, and the extrusion component is used to extrude the rod body from the end of the rod body to remove the gear blade from the rod body. The embodiments of this application can remove the gear blade from the rod body by extruding the end of the rod body with the extrusion component, avoiding the deformation of the gear blade caused by striking to remove the gear blade from the rod body, improving the protection effect on the gear blade, and improving the maintenance efficiency of the horizontal line roller.

[0033] In some scenarios, a maintenance device for a horizontal line roller in the embodiments of this application can be applied to the maintenance of the line roller of the horizontal line in PCB production, and can improve the maintenance efficiency of the horizontal line roller.

[0034] The following specifically describes a maintenance device and method for a horizontal line roller provided by the embodiments of this application with specific examples.

[0035] Figure 1 is a schematic structural diagram of a maintenance device for a horizontal line roller in the embodiments of this application. As Figure 1 shown, the maintenance device 1 is used to maintain the line roller 2. The line roller 2 includes a rod body 21, a roller blade 22, and a gear blade 23. The roller blade 22 is arranged in the middle of the rod body 21, and the gear blade 23 is arranged at the end of the rod body 21. The maintenance device 1 includes a fixing component 11 and an extrusion component 12. The fixing component 11 is used to fix the line roller 2, and the extrusion component 12 is used to extrude the rod body 21 from the end of the rod body 21 to remove the gear blade 23 from the rod body 21.

[0036] As Figure 1 shown in the figure, in terms of structure, the line roller 2 includes a rod body 21, roller pieces 22 and gear pieces 23. The roller pieces 22 are arranged in the middle of the rod body 21, and the number of roller pieces 22 is multiple. The gear pieces 23 are arranged at the ends of the rod body 21. The gear pieces 23 are used to transmit power on the rod body 21, and the gear pieces 23 can drive the rod body 21 and the roller pieces 22 to rotate.

[0037] In terms of structure, the maintenance device 1 is used to maintain the line roller 2, and thus can maintain the rod body 21, the roller pieces 22 and the gear pieces 23 of the line roller 2, achieving efficient maintenance of the rod body 21, the roller pieces 22 and the gear pieces 23.

[0038] In terms of structure, as Figure 1 shown in the figure, the maintenance device 1 includes a fixing component 11 and an extrusion component 12. The fixing component 11 is used to fix the line roller 2. After the line roller 2 is fixed by the fixing component 11, the extrusion component 12 can extrude the rod body 21 from the end of the rod body 21, so that the rod body 21 can move relative to the gear piece 23, and then the gear piece 23 can be removed from the rod body 21.

[0039] The beneficial effect brought by the above implementation method is that the rod body can be extruded from the end of the rod body through the extrusion component, so that the rod body can move relative to the gear piece, and then the gear piece can be automatically removed from the rod body, improving the maintenance efficiency of the line roller and effectively avoiding the deformation of the gear piece caused by knocking on the gear piece.

[0040] In some implementation methods, Figure 2 is Figure 1 a partial structural schematic diagram of the A part of the maintenance device of a horizontal line roller in Figure 4 is a structural schematic diagram of the maintenance device of a horizontal line roller in the first state in an embodiment of the present application. Figure 5 is Figure 4 a partial structural schematic diagram of the B part of the maintenance device of a horizontal line roller in Figure 6 is a structural schematic diagram of the maintenance device of a horizontal line roller in the second state in an embodiment of the present application. Figure 7 is Figure 6 a partial structural schematic diagram of the C part of the maintenance device of a horizontal line roller in Figures 1 to 7As shown, at both ends of the fixing component 11, there is respectively a gear groove 111 for positioning the gear piece 23. The gear groove 111 can position the gear piece 23. The extrusion component 12 includes two extrusion heads 121. Each extrusion head 121 can reciprocate along the length direction of the rod body 21. Each extrusion head 121 can push the rod body 21 in the gear groove 111 to move relative to the gear piece 23 along the length direction of the rod body 21, so that the rod body 21 and the gear piece 23 are separated.

[0041] As Figures 1 to 7 shown, in terms of structure, at both ends of the fixing component 11, there is respectively a gear groove 111 for positioning the gear piece 23. The gear groove 111 is used to accommodate the gear piece 23. The gear groove 111 can position the gear piece 23, and thus it is convenient to disassemble the gear piece 23 after positioning the gear piece 23.

[0042] As Figures 1 to 7 shown, the extrusion component 12 includes two extrusion heads 121. Each extrusion head 121 can reciprocate along the length direction of the rod body 21, so that the extrusion head 121 can extrude the gear piece 23.

[0043] During operation, each extrusion head 121 can push the rod body 21 in the gear groove 111 to move relative to the gear piece 23 along the length direction of the rod body 21, so that the rod body 21 and the gear piece 23 move relative to each other, and thus the gear piece 23 is separated from the rod body 21.

[0044] Exemplarily, the extrusion component 12 can be an extruder, the extrusion head 121 can be the extrusion head of the extruder, the diameter of the extrusion head 121 is the same as the diameter of the rod body 21, and the rod body 21 can be horizontally extruded through the extrusion head 121.

[0045] The beneficial effect brought by the above implementation manner is that the rod body can be horizontally extruded through the extrusion head, so that the gear piece and the rod body are separated, which is convenient for disassembling the gear piece. And the gear piece is positioned through the gear groove, improving the efficiency of disassembling and positioning the gear piece.

[0046] In some implementation manners, the fixing component 11 includes a base 112 and a top seat 113. The base 112 and the top seat 113 can abut against each other and separate from each other. There are multiple base cavities 112a for fixing the roller piece 22 on the base 112. There are multiple top seat cavities 113a corresponding to the base cavities 112a on the top seat 113. When the base 112 and the top seat 113 abut against each other, the base cavities 112a and the top seat cavities 113a can cooperate with each other to correct the position of the roller piece 22 on the rod body 21.

[0047] As Figures 1 to 7As shown, in terms of structure, it includes a base 112 and a top seat 113 which can be respectively connected to the base and the ram head of a vertical press. The base 112 and the top seat 113 can abut against each other and separate from each other under the drive of the vertical press, and then fix the traveling roller 2 through the base 112 and the top seat 113.

[0048] As Figures 1 to 7 shown, the base 112 is provided with a plurality of base cavities 112a for fixing the roller pieces 22. The top seat 113 is provided with a plurality of top seat cavities 113a corresponding to the base cavities 112a. The base cavities 112a and the top seat cavities 113a can cooperate with each other to fix the roller pieces 22, and then can fix and shape the roller pieces 22 on the traveling roller 2.

[0049] In terms of structure, the shape of the base cavity 112a can cooperate with the roller piece 22, and the shape of the top seat cavity 113a can cooperate with the roller piece 22. When working, when the base 112 and the top seat 113 abut against each other, the base cavity 112a and the top seat cavity 113a can cooperate with each other to correct the position of the roller piece 22 on the rod body 21.

[0050] The beneficial effect brought by the above implementation method is that the roller pieces are shaped on the rod body through the cooperation of multiple base cavities and multiple top seat cavities, improving the correction and shaping efficiency of the roller pieces on the rod body.

[0051] In some implementation methods, the base 112 is provided with a plurality of base rod cavities 112b for correcting the rod body 21. The top seat 113 is provided with a plurality of top seat rod cavities 113b corresponding to the base rod cavities 112b. When the base 112 and the top seat 113 abut against each other, the base rod cavities 112b and the top seat rod cavities 113b cooperate with each other to correct the shape of the rod body 21.

[0052] As Figures 1 to 7 shown, the base 112 is provided with a plurality of base rod cavities 112b for correcting the rod body 21. The top seat 113 is provided with a plurality of top seat rod cavities 113b corresponding to the base rod cavities 112b. The base rod cavities 112b and the top seat rod cavities 113b can cooperate with each other to shape the rod body 21, so that when the base 112 and the top seat 113 abut against each other, the base rod cavities 112b and the top seat rod cavities 113b cooperate with each other to correct the shape of the rod body 21.

[0053] Exemplarily, the cross sections of the base rod cavity 112b and the top seat rod cavity 113b can be semi-circular.

[0054] The beneficial effect brought by the above implementation method is that when the base and the top seat abut against each other, the base rod cavity and the top seat rod cavity cooperate with each other to correct the shape of the rod body.

[0055] In some implementations, an axial space 114 for the roller piece 22 to move axially on the rod body 21 is provided on the base cavity 112a and the top base cavity 113a. Before the rod body 21 and the gear piece 23 are disengaged, there is a spacing between the roller piece 22 and the end of the axial space 114. After the rod body 21 and the gear piece 23 are disengaged, the roller piece 22 can abut against the end of the axial space 114.

[0056] As Figures 1 to 7 shown, structurally, an axial space 114 for the roller piece 22 to move axially on the rod body 21 is provided on the base cavity 112a and the top base cavity 113a, so that the roller piece 22 can move laterally within the axial space 114. When the rod body 21 moves axially, the roller piece 22 moves together with the rod body 21.

[0057] As Figures 4 to 7 shown, before the rod body 21 and the gear piece 23 are disengaged, there is a spacing between the roller piece 22 and the end of the axial space 114, so that the roller piece 22 will not be blocked by the side walls of the base cavity 112a and the top base cavity 113a, enabling the rod body 21 to move laterally relative to the base cavity 112a and the top base cavity 113a smoothly, and enabling the rod body 21 and the gear piece 23 to be disengaged smoothly.

[0058] In use, after the rod body 21 and the gear piece 23 are disengaged, the roller piece 22 can abut against the end of the axial space 114, so that the roller piece 22 can be blocked by the side walls of the base cavity 112a and the top base cavity 113a, enabling the side walls of the base cavity 112a and the top base cavity 113a to block the entire row of pulleys 2 axially on the rod body 21, ensuring the stability of the fixation of the row of pulleys 2.

[0059] The beneficial effects brought by the above implementations are that the roller piece will not be blocked by the side walls of the base cavity and the top base cavity, enabling the rod body to move laterally relative to the base cavity and the top base cavity smoothly, and enabling the rod body and the gear piece to be disengaged smoothly.

[0060] The beneficial effects brought by the above implementations also lie in that after the rod body and the gear piece are disengaged, the side walls of the base cavity and the top base cavity can block the entire row of pulleys axially on the rod body, ensuring the stability of the fixation of the row of pulleys.

[0061] In some implementations, the extrusion assembly 12 further includes a force measuring assembly 122 and a control assembly 123. The force measuring assembly 122 is used to detect the rod extrusion force value of the extrusion head 121 on the rod body 21. When the rod extrusion force value is greater than a preset pressure value, the control assembly 123 controls the extrusion head 121 to stop extruding the rod body 21.

[0062] Figure 8The figure is a schematic diagram of the control structure of a maintenance device for a horizontal line roller in an embodiment of the present application. As Figure 8 shown, in terms of structure, the extrusion assembly 12 further includes a force measuring assembly 122 and a control assembly 123. The force measuring assembly 122 is used to detect the rod extrusion force value of the extrusion head 121 on the rod body 21, so that the force measuring assembly 122 can monitor the extrusion force of the extrusion head 121 on the rod body 21.

[0063] When in use, when the rod extrusion force value is greater than the preset pressure value, it indicates that the extrusion pressure of the extrusion head 121 on the rod body 21 is too large. In order to protect the rod body 21, the control assembly 123 can be used to control the extrusion head 121 to stop extruding the rod body 21, thereby realizing the protection of the rod body 21.

[0064] The beneficial effect brought by the above implementation method is that by detecting the extrusion force on the rod body, when the extrusion force on the rod body is too large, the extrusion of the rod body can be stopped, improving the protection effect on the rod body.

[0065] The embodiment of the present application also provides a maintenance method for a horizontal line roller. This method is realized by the above-mentioned maintenance device for a horizontal line roller, and this method includes S110 to S120.

[0066] S110. Fix the line roller 2 through the fixing assembly 11.

[0067] When in use, after the line roller 2 is fixed through the fixing assembly 11, the line roller 2 can be maintained by the mutual cooperation of the fixing assembly 11 and the extrusion assembly 12.

[0068] S120. Extrude the rod body 21 from the end of the rod body 21 through the extrusion assembly 12 to remove the gear piece 23 from the rod body 21.

[0069] When in use, the rod body 21 can be extruded from the end of the rod body 21 through the extrusion assembly 12 to remove the gear piece 23 from the rod body 21. While realizing the extrusion of the rod body 21, by positioning the gear piece 23, the uneven force on the gear piece 23 is avoided, and the protection effect on the gear piece 23 is improved.

[0070] The beneficial effect brought by the above implementation method is that the extrusion assembly extrudes the rod body from the end of the rod body to remove the gear piece from the rod body, improving the protection effect on the gear piece.

[0071] In some implementation methods, the above method further includes S210 to S220, and the following is a specific description of S210 to S220.

[0072] S210. After placing the line roller 2 on the base 112, the base 112 and the top base 113 approach and abut against each other. The roller piece 22 is corrected through the base cavity 112a and the top base cavity 113a, and the rod body 21 is corrected through the cooperation of the base rod cavity 112b and the top base rod cavity 113b.

[0073] During use, as Figure 1 shown, after placing the line roller 2 on the base 112, the base 112 and the top base 113 approach and abut against each other. The roller piece 22 is corrected through the base cavity 112a and the top base cavity 113a, and the rod body 21 is corrected through the cooperation of the base rod cavity 112b and the top base rod cavity 113b, enabling the base 112 and the top base 113 to cooperate with each other to correct the roller piece 22 and the rod body 21, achieving efficient correction of the roller piece 22 and the rod body 21.

[0074] S220. The base 112 and the top base 113 are separated from each other to generate a gap, and the rod body 21 is extruded from the end of the rod body 21 by the extrusion head 121 to remove the gear piece 23 from the rod body 21.

[0075] During use, after correcting the roller piece 22 and the rod body 21, the base 112 and the top base 113 can be driven to separate from each other to generate a gap, enabling the rod body 21 to move horizontally between the base 112 and the top base 113, facilitating the removal of the gear piece 23 from the rod body 21.

[0076] During use, when disassembling the gear piece 23, the rod body 21 can be extruded from the end of the rod body 21 by the extrusion head 121 to remove the gear piece 23 from the rod body 21.

[0077] The beneficial effects brought by the above implementation method are that the roller piece and the rod body can be corrected efficiently, and the gear piece can be efficiently removed from the rod body by extruding the rod body from the end of the rod body by the extrusion head.

[0078] In some implementation methods, in the above S220, extruding the rod body 21 from the end of the rod body 21 by the extrusion head 121 to remove the gear piece 23 from the rod body 21 includes: detecting the rod body extrusion force value of the extrusion head 121 on the rod body 21, and when the rod body extrusion force value is less than or equal to the preset pressure value, controlling the extrusion head 121 to continuously extrude the rod body 21. When the rod body extrusion force value is greater than the preset pressure value, controlling the extrusion head 121 to stop extruding the rod body 21.

[0079] During use, the rod extrusion force value of the extrusion head 121 on the rod body 21 can be detected first. When the rod extrusion force value is less than or equal to the preset pressure value, the extrusion head 121 is controlled to continuously extrude the rod body 21. At this time, it indicates that there is a gap between the roller piece 22 and the end of the axial space 114, so that the roller piece 22 will not be blocked by the side walls of the base cavity 112a and the top seat cavity 113a, enabling the gear piece 23 to smoothly disengage from the rod body 21.

[0080] Exemplarily, the preset pressure value can be 1.5 times the frictional force between the rod body 21 and the gear piece 23 during relative sliding.

[0081] During use, when the rod extrusion force value is greater than the preset pressure value, the roller piece 22 abuts against the end of the axial space 114, indicating that the roller piece 22 is blocked by the side walls of the base cavity 112a and the top seat cavity 113a. The extrusion head 121 is controlled to stop extruding the rod body 21, which can protect the roller piece 22 and the rod body 23.

[0082] The beneficial effects brought by the above implementation method are that by detecting the extrusion force on the rod body, the extrusion of the gear piece and the separation of the rod body can be automatically completed, and the rod body can be protected when the extrusion force on the rod body is too large.

[0083] In some implementation methods, the above method further includes: placing the gear piece 23 to be installed in the gear groove 111, replacing the extrusion head 121 on the side where the gear piece 23 to be installed is located with an extrusion plate that supports the gear piece 23, and extruding the rod body 21 through the extrusion head 121 on the side opposite to the gear piece 23 to be installed, so that the rod body 21 can be inserted into the shaft hole of the gear piece 23 to be installed. Among them, the gear piece 23 is provided with a guiding portion for guiding the rod body 21.

[0084] During use, in order to squeeze and install the gear piece 23 onto the rod body 21 again, the extrusion head 121 on the side where the gear piece 23 to be installed is located can be replaced with an extrusion plate that supports the gear piece 23. Then, the gear piece 23 is squeezed onto the rod body 21 through the extrusion plate, and the rod body 21 is extruded through the extrusion head 121 on the side opposite to the gear piece 23 to be installed, so that the rod body 21 can be inserted into the shaft hole of the gear piece 23 to be installed, that is, the purpose of installing the gear piece 23 onto the rod body 21 is achieved.

[0085] In terms of structure, the gear piece 23 is provided with a guiding portion for guiding the rod body 21, enabling the rod body 21 to smoothly insert into the shaft hole of the gear piece 23.

[0086] Exemplarily, the guiding portion can be a chamfer structure for guiding the rod body 21.

[0087] The beneficial effects brought by the above implementation method are that it is convenient to install gear pieces on the rod body, and further improves the maintenance efficiency of the walking wheel.

[0088] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
