[0002] The glass deep processing line roller conveyor is a key piece of equipment that automatically conveys, positions, corrects, and starts / stops glass, connecting all the process equipment in the production line to realize the deep processing of glass.

[0003] Inline roller conveyors are typically composed of multiple connected roller conveyor units, each consisting of a roller conveyor frame, conveyor rollers, a drive motor, and a gear transmission system. With the development of the glass manufacturing industry, the requirements for the smoothness and precision of inline roller conveyor transport are becoming increasingly stringent, with conveyor roller surface runout accuracy ≤0.2mm.

[0004] The main performance indicators of the connecting roller conveyor frame, which serves as the foundation for laying the conveyor rollers, are as follows: flatness of the mounting surface of the large plate on the drive side ≤ 0.15mm, flatness of the mounting surface of the channel steel on the non-drive side ≤ 0.1mm, parallelism between the mounting surface of the large plate on the drive side and the mounting surface of the non-drive side ≤ 0.15mm, height difference between the mounting surface of the large plate on the drive side and the mounting surface of the non-drive side ≤ 0.2mm, parallel alignment of the bearing mounting holes on the drive side and the bearing mounting holes on the non-drive side with a diagonal difference ≤ 1mm, and perpendicularity of the motor mounting plate on the drive side and the mounting surface of the large plate on the drive side ≤ 0.2mm. The technical indicators of the connecting roller conveyor frame directly affect the runout accuracy of the main conveyor roller surface.

[0005] The existing manufacturing process for roller conveyor frames is as follows:

[0006] Step 1. Prepare materials, including channel steel components, support leg components, motor mounting plate, set screw plate, transmission side plate, reinforcing rib plate, fixed-length rectangular tube and square tube body;

[0010] Step 5. Assemble and weld the transmission side plate, the non-transmission side plate, and the square tube body;

[0011] Step 6. CNC gantry milling: large plate surface on the transmission side, bearing mounting holes on the large plate surface, channel steel mounting surface on the non-transmission side, bearing mounting holes on the channel steel surface, and motor mounting plate surface.

[0012] The problem with conventional methods is that manual positioning and clamping are required when welding the transmission side and the non-transmission side, resulting in low production efficiency.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0069] See Figures 1-3 It should be noted in advance that the roller conveyor frame is the core support structure of the roller conveyor system, used to install and fix components such as rollers and drive devices.

[0070] Overall, the shape of the roller conveyor frame is similar to a horizontally placed "ladder" frame structure. With the center of the roller conveyor frame as the origin O, the length direction of the roller conveyor frame is the X-axis, the width direction of the roller conveyor frame is the Y-axis, and the height direction of the roller conveyor frame is the Z-axis, a first three-dimensional coordinate system is established.

[0071] Therefore, the side of the roller conveyor frame along the X-axis is the transmission side, and the drive motor and gear transmission system used for transmission are both installed on the transmission side.

[0072] The other side of the roller conveyor frame along the X-axis is the non-drive side, which mainly serves as a support and guide.

[0073] The transmission side and the non-transmission side are welded together by several square tube bodies 19a. The square tube bodies 19a are parallel to the Y-axis, and finally form a "ladder-shaped" frame. The conveyor rollers are mounted on both sides of the roller frame.

[0074] Specifically, the roller conveyor frame is welded together from at least the transmission side plate 10, the first channel steel assembly 11, the reinforcing rib plate 12, the first support leg assembly 13, the motor mounting plate 14, the top screw plate, the first fixed-length rectangular tube 16, the second channel steel assembly 17, the second support leg assembly 18, the second fixed-length rectangular tube 19, and the square tube body 19a.

[0075] First, regarding the transmission side;

[0076] The transmission side plate 10 is arranged along the X-axis and is located at the core of the transmission side. It serves as the reference and mounting platform for the entire transmission side. The top surface of the transmission side plate 10 has a first bearing seat mounting hole 10d, which is used to install the first bearing seat (not shown in the figure). The first bearing seat installs the first bearing (not shown in the figure) at one end of the conveyor roller.

[0077] The first channel steel assembly 11 is arranged along the Z-axis and welded to the underside of the transmission side plate 10.

[0078] A reinforcing rib 12 is welded between the first channel steel assembly 11 and the transmission side plate 10 to enhance their rigidity, thereby jointly forming the transmission side plate assembly.

[0079] The first leg assembly 13 is arranged along the Z-axis and welded to the bottom of the first channel steel assembly 11 to support the roller conveyor frame.

[0080] The motor mounting plate 14 is welded onto the first leg assembly 13. Its mounting surface needs to be cut to ensure that it is perpendicular to the surface of the transmission side plate 10, and is used to mount the motor.

[0081] The set screw plate consists of four small parts on the motor mounting plate 14. After the conveyor roller is installed, it is used to adjust the Z-axis position of the motor to ensure the tension of the synchronous belt connecting the motor and the conveyor roller.

[0082] The first fixed-length rectangular tube 16 is arranged along the X-axis and is used to connect the first support leg assembly 13.

[0083] The above transmission side components are welded together to form the transmission side plate.

[0084] Secondly, regarding the non-transmission side;

[0085] The second channel steel assembly 17 is arranged along the Z-axis and serves as the main structure on the non-transmission side. The top surface of the second channel steel assembly 17 has a second bearing housing mounting hole 17d, which is used to install the second bearing housing (not shown in the figure). The bearing housing is used to install the second bearing (not shown in the figure) at the other end of the conveyor roller.

[0086] The second leg assembly 18, arranged along the Z-axis, is welded to the bottom of the second channel steel assembly 17 and is used to support the roller conveyor frame.

[0087] The second fixed-length rectangular tube 19 is arranged along the X-axis and is used to connect the second support leg assembly 18.

[0088] The above non-drive side panels are welded together to form the non-drive side pieces.

[0089] Then, regarding the square tube body 19a;

[0090] The square tube body 19a, arranged along the Y-axis, is used to connect the transmission side plate and the non-transmission side plate, and is welded between the two side plates.

[0091] It should be noted in advance that, taking the roller conveyor frame assembled and welded at this moment as the reference, the top surface of the transmission side large plate assembly is defined as the first mounting surface 10c, and the top surface of the second channel steel assembly 17 is defined as the second mounting surface 17c.

[0092] The following process requirements must be ensured during the processing:

[0093] The flatness of the first mounting surface 10c is ≤0.15mm.

[0094] The flatness of the second mounting surface 17c is ≤0.1mm.

[0095] The height difference between the first mounting surface 10c and the second mounting surface 17c is ≤0.2mm.

[0096] The parallelism between the first mounting surface 10c and the second mounting surface 17c is ≤0.15mm.

[0097] The first bearing housing mounting hole 10d and the second bearing housing mounting hole 17d are parallel and aligned, with a diagonal difference of ≤1mm.

[0098] The perpendicularity between the first mounting surface 10c and the motor mounting plate 14 is ≤0.2mm.

[0099] It is worth mentioning that the diagonal difference ≤1mm refers to the difference between the line connecting the foremost first bearing housing mounting hole 10d and the rearmost second bearing housing mounting hole 17d along the X-axis and the line connecting the foremost second bearing housing mounting hole 17d and the rearmost first bearing housing mounting hole 10d, which is ≤1mm. All the above component placement orientations are described based on the first three-dimensional coordinate system.

[0100] See Figure 4 The main steps involved in the processing of the roller conveyor frame are as follows:

[0101] S1. Prepare the welding materials;

[0102] S2. The first positioning fixture positions and clamps the transmission side plate 10, the first channel steel assembly 11, and the reinforcing rib plate 12, and then welds them together to form the transmission side plate assembly.

[0103] S3. Assemble and weld the transmission side plate assembly, the first support leg assembly 13, the motor mounting plate 14, the set screw plate, and the first fixed-length rectangular tube 16 to form the transmission side plate;

[0104] S4. Weld the second channel steel assembly 17, the second leg assembly 18, and the second fixed-length rectangular tube 19 together to form a non-transmission side plate;

[0105] S5. The second positioning fixture clamps the transmission side plate and mills the mounting surface of the transmission side plate;

[0106] S6. Mill the mounting surface of the non-transmission side plate;

[0107] S7. The first positioning fixture clamps the transmission side plate, the square tube body 19a and the non-transmission side plate, and welds them together to form a roller frame;

[0108] S8. Drill the first bearing housing mounting hole 10d and the second bearing housing mounting hole 17d.

[0109] See Figures 5-12In this embodiment, the first positioning fixture is applied in S2, S3 and S7. When applied in steps S2 and S3, it is used to position and clamp the transmission side plate 10, the first channel steel assembly 11 and the reinforcing rib plate 12, so as to facilitate the welding to form the transmission side plate assembly.

[0110] Specifically, the first positioning fixture includes a first worktable 20, a clamping pad 21, a first side-fitting limiting block 22, a large plate limiting block 23, a first channel steel limiting block 24, a large plate pressing mechanism 25, a first component pressing mechanism 26, a first channel steel web plate clamping mechanism, and a first lateral clamping mechanism 28.

[0111] The first worktable 20 is flat. The upper surface of the first worktable 20 is the reference surface. The center of the first worktable 20 is point O. The length direction of the first worktable 20 is the x-axis, the width direction of the first worktable 20 is the y-axis, and the height direction of the first worktable 20 is the z-axis. A second three-dimensional coordinate system is established.

[0112] The first workbench 20 is provided with a fixture pad 21. The fixture pad 21 is located on one side of the x-axis, and the long side of the fixture pad 21 is parallel to the x-axis.

[0113] The first workbench 20 is equipped with a first side-fitting limiting block 22, a large plate limiting block 23, and a first channel steel limiting block 24, all of which are limiting blocks. The first channel steel limiting block 24 has an inverted "L" shape, therefore, the top side of the first channel steel limiting block 24 protrudes beyond the large plate limiting block 23, thus allowing them to be combined for positioning the transmission-side large plate 10 and the first channel steel assembly 11; specifically...

[0114] Three large plate limiting blocks 23 are evenly arranged along the x-axis on the first workbench 20. A first side-fitting limiting block 22 is set on the left side of the first workbench 20. The first side-fitting limiting block 22 and the large plate limiting block 23 are not on the same horizontal line.

[0115] Three first channel steel limit blocks 24 are evenly arranged along the x-axis on the first workbench 20.

[0116] Four large plate clamping mechanisms 25 are arranged along the x-axis of the first workbench 20. The large plate clamping mechanism 25 is used to clamp the large plate 10 on the transmission side. Specifically, the large plate clamping mechanism 25 includes a first bracket 250, a large plate clamping cylinder 251 and a pressure block body 252. The first bracket 250 is arranged on the upper surface of the first workbench 20. The longitudinal section of the first bracket 250 is an inverted L-shaped structure. The large plate clamping cylinder 251 is arranged on the crossbeam of the first bracket 250. The piston rod of the large plate clamping cylinder 251 is downward along the z-axis. The pressure block body 252 is arranged at the bottom end of the piston rod of the large plate clamping cylinder 251. The pressure block body 252 is pressed against the top surface of the large plate 10 on the transmission side.

[0117] It is worth mentioning that the first channel steel assembly 11 includes a first web 110 and a first wing 111, with the first wing 111 provided on both sides of the first web 110 to form a U-shaped channel steel structure.

[0118] Two first component clamping mechanisms 26 are arranged along the x-axis on the first worktable 20. The first component clamping mechanism 26 is used to clamp the first wing plate 111. Specifically, the first component clamping mechanism 26 includes a second bracket 260 and a first component clamping cylinder 261. The first worktable 20 is provided with the second bracket 260, and the first component clamping cylinder 261 is provided on the second bracket 260. The first component clamping cylinder 261 is a rotary clamping cylinder. During the extension and retraction of the piston rod of the rotary clamping cylinder, it can rotate 90° to the right or left and clamp the top of the first wing plate 111 through the clamping arm. This is prior art and will not be described in detail.

[0119] The first workbench 20 is equipped with three first channel steel web clamping mechanisms along the x-axis. The first channel steel web clamping mechanisms are used to clamp the first web 110. The first channel steel web clamping mechanism includes a third support 270, a third cylinder 271, a first pin 272, a third clamping arm 273, a second pin 274, a third support rod 275, and a third pin 276. The first workbench 20 is equipped with a third support 270. The longitudinal section of the third support 270 has an "L"-shaped structure. The third cylinder 271 is installed on the longitudinal beam of the third support 270. The piston rod of the third cylinder 271 is parallel to the y-axis. The piston rod of the third cylinder 271 is connected to the third clamping arm 273 through the first pin 272. The third clamping arm 273 has a hook-shaped structure. The middle part of the third clamping arm 273 is connected to one end of the third support rod 275 through the second pin 274. The other end of the third support rod 275 is connected to the support through the third pin 276. The support is set on the side of the third support (270).

[0120] It should be noted that the fixed end of the third cylinder 271 can be understood as the outer shell of the third cylinder 271, and the piston rod of the third cylinder 271 is the piston rod of the third cylinder 271. When the piston rod of the third cylinder 271 moves, it drives one end of the third clamping arm 273 to move. Due to the restriction of the third support rod 275, the middle part of the third clamping arm 273 rotates vertically around the second pin 274 until the third clamping arm 273 is locked on the outside of the first web.

[0121] A first lateral clamping mechanism 28 is provided on the right side of the first worktable 20. The first lateral clamping mechanism 28 cooperates with the first side-fitting limiting block 22 to clamp the transmission side plate 10 and the two ends of the first channel steel assembly 11. Specifically, the first lateral clamping mechanism 28 includes a fourth bracket 280 (not marked in the figure), a lateral clamping cylinder 281, and a first OK fixture 282. The fourth bracket 280 is provided on the right side of the first worktable 20, and the lateral clamping cylinder 281 is provided on the fourth bracket 280. The lateral clamping cylinder 281 is provided at the end of the fourth bracket 280 facing the first side-fitting limiting block 22. The piston rod of the lateral clamping cylinder 281 is arranged along the x-axis and connected to the first OK fixture 282. The first OK fixture 282 is a general-purpose fixture for machining, mainly used to clamp workpieces on machine tools for processing or inspection. It is existing technology and will not be described in detail.

[0122] The first positioning fixture is used to clamp the transmission side plate 10, the first channel steel assembly 11, and the reinforcing rib plate 12, facilitating the assembly welding process to form the transmission side plate assembly as follows:

[0123] S20.

[0125] It is worth mentioning that the opening side of the first channel steel assembly 11 refers to the U-shaped opening side of the first channel steel assembly 11. At this time, the transmission side plate 10 is in contact with the clamping pad 21, and the first channel steel assembly 11 is placed on the upper surface of the transmission side plate 10.

All of the above components are arranged on the table surface of the first workbench 20 and are located on the other side of the x-axis away from the fixture pad 21, for clamping the non-transmission side piece.

[0140] A second side-fitting limiting block 29 is provided on the left side of the first workbench 20. The second side-fitting limiting block 29 has the same structure as the first side-fitting limiting block 22.

[0141] The first worktable 20 is provided with three second channel steel limiting blocks 30 along the x' axis. The second channel steel limiting blocks 30 have the same structure as the first channel steel limiting blocks 24 and are used to position the second channel steel assembly 17.

[0142] The first worktable 20 is provided with three leg clamping mechanisms 31 along the x' axis for clamping the second leg assembly 18. Specifically, each leg clamping mechanism 31 includes a sixth bracket 310, a leg clamping cylinder 311, a fourth pin 312, a fourth clamping arm 313, a fifth pin 314, a fourth support rod 315, and a sixth pin 316. The sixth bracket 310 is provided on the first worktable 20. The sixth bracket 310 has an inverted L-shaped structure. The crossbeam of the sixth bracket 310 is equipped with the leg clamping cylinder 311. The piston rod is connected to the fourth clamping arm 313 via the fourth pin 312. The axis of the fourth pin 312 is parallel to the z' axis. The fourth clamping arm 313 has a hook-shaped structure. The middle part of the fourth clamping arm 313 is connected to one end of the fourth support rod 315 via the fifth pin 314.

[0144] Three first square tube limiting blocks 35 are arranged along the x' axis in the middle of the first workbench 20, respectively abutting against the side of the square tube body 19a, and are used to position the square tube body 19a located below.

[0145] The first workbench 20 has two second square tube limiting blocks 36 placed on both sides of the x' axis. The top of the second square tube limiting block 36 has an L-shaped structure to position the square tube body 19a located on the upper two sides.

The top of the third-party tube limiting block 37 has an inverted T-shaped structure to position the square tube body 19a located in the upper center.

[0147] It is worth noting that there are three columns of square tube body 19a along the x' axis; and each column has two layers along the z' axis. Therefore, the square tube body 19a located in the upper layer is the upper square tube body 19a, and the square tube body 19a located in the lower layer is the lower square tube body 19a. The square tube body 19a located in the middle column of the upper layer is the square tube body 19a located in the middle of the upper layer, and the two columns of square tube body 19a located on the two sides of the upper layer are the square tube body 19a located on the two sides of the upper layer.

[0148] A second lateral clamping mechanism 34 is provided on the right side of the first workbench 20. The second lateral clamping mechanism 34 has the same structure as the first lateral clamping mechanism 28. It works in conjunction with the second side fitting limit block 29 to clamp both ends of the second channel steel assembly 17. Further details are omitted.

[0149] The first positioning fixture is used for positioning and clamping in the following process:

[0150] The first positioning fixture clamps the transmission side piece, the non-transmission side piece and the square tube body 19a, and welds them together to form a roller frame, specifically including the following steps;

[0151] S70. Clamp the transmission side plate, refer to S20~S24, and will not be repeated here.

[0152] S71. Clamp the non-drive side plate, specifically including the following steps;

[0153] S710. Positioning the non-transmission side plate; specifically, the second channel steel assembly 17 has its opening facing the side, the second side fitting limit block 29 is fitted with the end face of the second wing plate, and the second channel steel limit block 30 is fitted with the side of the second wing plate.

[0154] S711. The outrigger clamping cylinder 311 clamps the second outrigger assembly 18; specifically, the outrigger clamping cylinder 311 is activated, which drives the fourth clamping arm 313 to rotate around the fifth pin 314 until it is locked onto the surface of the second outrigger assembly 18.

[0155] S712. The second component clamping mechanism 32 clamps the second wing plate; specifically, see S230, which will not be repeated here.

[0156] S713. The second channel steel web clamping mechanism 33 clamps the second web; specifically, see S231, which will not be repeated here.

[0157] S714. The second lateral tightening mechanism 34 fixes the second channel steel assembly 17; specifically, the second lateral tightening mechanism 34 is activated, see S24, which will not be repeated here.

[0158] S715. Position the square tube body 19a; specifically, place three square tube bodies 19a on the first worktable 20, so that the three square tube bodies 19a respectively abut against the sides of the first square tube limiting block 35, the second square tube limiting block 36 and the third square tube limiting block 37.

[0159] S72. The welded square tube body 19a, the driving side plate and the non-driving side plate form a roller frame, which is existing technology and will not be described in detail here.

[0160] S73. Remove the roller conveyor frame; specifically including the following steps;

[0161] S730. Remove the restrictions on the transmission side plate assembly. See S27 for details.

[0162] S731. Release the restriction on the non-transmission side plate; specifically, reverse drive the second lateral clamping mechanism 34 to release the fixation on the right side of the second channel steel assembly 17; reverse drive the outrigger clamping cylinder 311, the second channel steel web clamping mechanism 33, and the second assembly pressing mechanism 32 to release the restriction on the non-transmission side plate and remove the roller frame.

[0163] It is worth mentioning that the placement of all the components is described based on the second three-dimensional coordinate system. In fact, corresponding to the first three-dimensional coordinate system, the bottom surface of the transmission side plate assembly is the first mounting surface 10c, and the bottom surface of the non-transmission side plate is the second mounting surface 17c.

[0164] Therefore, it is necessary to ensure that during the S7 process, the height difference between the first mounting surface 10c and the second mounting surface 17c is ≤0.2mm; and the parallelism between the first mounting surface 10c and the second mounting surface 17c is ≤0.15mm.

[0165] The first positioning fixture claimed in this embodiment firstly uses a dedicated first positioning fixture transmission side plate 10 and first channel steel assembly 11 for positioning and clamping. This eliminates the problems of poor accuracy and inconsistent performance caused by relying on the skills and experience of welders for manual marking, positioning and splicing in the prior art. In fact, the large welding deformation leaves a great deal of "remedial" pressure for the subsequent milling process. Therefore, this embodiment solves the problem at the source. As long as the first positioning fixture itself is manufactured accurately, each workpiece is positioned with the same reference and fixed with the same clamping force; the welding parameters are consistent, and the quality of each transmission side plate assembly produced is highly consistent, stable and predictable. This achieves standardized and large-scale production, with a very high product qualification rate and almost no scrap due to welding positioning errors.

[0166] Therefore, in the S2, not only can positioning and automatic clamping be achieved quickly, reducing clamping time from minutes to seconds and significantly reducing labor intensity, but it also reduces reliance on highly skilled welders and significantly accelerates the production cycle.

[0167] Moreover, in S7, the first positioning fixture can also be used to clamp the transmission side plate, the square tube body 19a, and the non-transmission side plate. This means that although the fixture is a dedicated system designed to achieve specific accuracy targets, it exhibits significant general-purpose functionality in the production process, demonstrating good process integration and flexibility.

[0168] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
