A laser scanner-assisted workbench for manufacturing motorcycle cover molds

Abstract

The present invention provides a laser scanner auxiliary workbench for manufacturing motorcycle cover molds, which belongs to the technical field of mold inspection tools. The workbench comprises a base frame assembly, a fixed ring rail assembly, a dynamic ring rail assembly, a surrounding scanning assembly, a secondary scanning assembly and a safety limit seat component. The symmetrically distributed flip frame can be flipped synchronously to eliminate contact interference with the surrounding scanning assembly during mold placement. After the flip frame is flipped upward into position, the dynamic ring rail is aligned with the fixed ring rail and the dynamic straight rail is aligned with the solid straight rail. This allows the surrounding scanning assembly to move along the overall circular path formed by the dynamic ring rail and the fixed ring rail, and allows the translation frame to move from a state of sliding cooperation with the solid straight rail to a state of sliding cooperation with the dynamic straight rail, thereby comprehensively and accurately performing scanning and inspection work on the mold. In addition, during the process of the flip frame flipping upward, the pushing arc surface and the passive arc surface can form a sliding tangent cooperation, so that the dynamic straight rail can be connected with the solid straight rail on a safe basis.

Description

Technical Field

[0001] The invention relates to the technical field of mold inspection tools, in particular to a laser scanner auxiliary workbench for manufacturing motorcycle cover molds. Background Art

[0002] Motorcycle covers (also known as motorcycle shells or exterior trims) are important components installed on the outside of the frame, mainly used for functional protection and appearance beautification; most of them are made of plastic parts, and most of them have complex curved shapes and require injection molding. Therefore, the manufacturing quality of the injection mold is directly related to the overall functionality and appearance of the motorcycle after assembly.

[0003] Existing motorcycle injection mold size and shape detection still relies heavily on manual inspection, which has the following disadvantages:

[0004] 1. Low detection efficiency and slow manual detection speed. It is necessary to measure multiple key dimensions of the cover parts one by one, which is difficult to meet the needs of mass production and cannot adapt to the efficient production rhythm of the modern injection molding industry;

[0005] 2. Detection accuracy is greatly affected by subjective factors. Manual detection depends on the operator's experience, vision, and fatigue level, which may lead to misjudgment or missed detection.

[0006] 3. Poor testing consistency and difficulty in standardization. Different quality inspectors may have different judgment standards for the same product, resulting in quality fluctuations;

[0007] 4. It is impossible to fully cover the complex surface detection. Motorcycle covers usually have complex surfaces (such as streamlined shells), and manual inspection tools are difficult to accurately measure the deviation of free-form surfaces. Summary of the Invention

[0008] The purpose of the present invention is to provide a laser scanner auxiliary workbench for the manufacture of motorcycle cover molds. In conjunction with the flipping action of the flip frame, the dynamic ring rail can form an integral circular path with the fixed ring rail, and the dynamic straight rail and the fixed straight rail are aligned and connected. It can not only achieve the purpose of installing, hoisting and placing the mold, but also can use the cooperation of the surrounding scanning component and the auxiliary scanning component to comprehensively and accurately scan and detect the mold.

[0009] The objective of the present invention is achieved through such a technical solution, a laser scanner auxiliary workbench for manufacturing motorcycle cover molds, comprising a base frame assembly, a fixed ring rail assembly, a dynamic ring rail assembly, a surround scanning assembly and a secondary scanning assembly, wherein the fixed ring rail assembly comprises a fixed ring rail, the dynamic ring rail assembly comprises a flip frame and a flip axis, the surround scanning assembly comprises a moving frame and a surround laser scanning probe, and the secondary scanning assembly comprises a translation frame and a secondary laser scanning probe;

[0010] The fixed ring rail is symmetrically fixed to the top of the base frame assembly, and the flip frame is symmetrically screwed to the inner surface of the top of the base frame assembly through the flip axis. The outer top of each set of flip frames is fixed with a dynamic ring rail, and each set of flip axis is fixed with a pair of synchronous gears, and the flip axes on the same side are meshed and connected;

[0011] The movable frame can slide along the fixed ring rail and the dynamic ring rail. The surrounding laser scanning probe is installed on the inner side of the top of the movable frame. The top side of the base frame assembly is symmetrically fixed with a fixed straight rail. The two sides of the bottom end of the translation frame are respectively slidably connected with different fixed straight rails. The auxiliary laser scanning probe is installed in the inner middle part of the top of the translation frame. The outer top side of each group of flip frames is fixed with a dynamic straight rail. After the flip frame is flipped upward into place, the dynamic ring rail can form a complete circular structure with the fixed ring rail, and the solid straight rails on the same side are aligned and connected with the dynamic straight rails.

[0012] The use process of the technical solution of the present invention is as follows:

[0013] The top middle part of the chassis assembly is used to place the mold to be scanned and inspected;

[0014] Before testing, the surround scanning assembly needs to be automatically moved to a position where it slides with the dynamic ring rail, and the flip frame needs to be flipped down into place;

[0015] Before testing, the translation frame automatically slides to the starting position at one end of the fixed straight rail;

[0016] After the mold is hoisted and placed in the middle of the top of the base frame assembly, the rotary drive mechanism connected to one of the flip frames is started to drive the flip frame to rotate with the flip axis as the reference. With the cooperation of the synchronous gears on the same side to form a transmission connection, the two symmetrically distributed flip frames can keep rotating synchronously towards each other. As the two flip frames are flipped up synchronously, after the flip frames are flipped up into place, the dynamic ring rail and the fixed ring rail are aligned and connected, and the symmetrically distributed dynamic ring rails and the symmetrically distributed fixed ring rails together form a complete circular path;

[0017] The movable frame can automatically move along the dynamic ring rail. After the dynamic ring rail and the fixed ring rail are aligned and connected, the movable frame can also automatically move along the complete circular path formed by the dynamic ring rail and the fixed ring rail, driving the surrounding laser scanning probe to perform a surrounding scan of the mold.

[0018] After the flip frame flips upward into position, the fixed straight rail and the movable straight rail on the same side are aligned and connected, so that the translation frame can not only move automatically along the fixed straight rail, but also move from the fixed straight rail to a position where it slides with the movable straight rail, thereby allowing the translation frame to move horizontally above the mold, and the auxiliary laser scanning probe and the surrounding laser scanning probe are used to jointly scan and detect the mold.

[0019] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0020] (1) The present invention utilizes a symmetrically distributed and synchronously flippable flip frame to separate and combine the movable ring rail with the fixed ring rail. After the surround scanning assembly is moved as a whole to a position that matches the movable ring rail, the flip frame flips downward into place, placing the surround scanning assembly in a relatively safe position relative to the mold detection placement position, thereby protecting the surround laser scanning probe from being affected by the mold hoisting.

[0021] (2) After the turning frame of the present invention is turned upward into position, the symmetrically distributed moving ring rails and the symmetrically distributed fixed ring rails can form a complete circular ring structure, which can provide a path for the surrounding scanning component to move around the mold;

[0022] (3) According to the present invention, after the flip frame flips upward into position, the movable straight rail fixed on the outer top side of the flip frame is aligned with the fixed straight rail at the fixed position, so that the translation frame can slide from the state of sliding cooperation with the fixed straight rail to the state of sliding cooperation with the movable straight rail. On the basis of the scanning and detection of the mold by the surrounding laser scanning probe, the auxiliary role formed by the auxiliary laser scanning probe can be used to comprehensively and accurately scan and detect the mold.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] like Figures 1-13 As shown, a laser scanner-assisted workbench for manufacturing motorcycle cover molds has a fixed ring rail 202 symmetrically fixed to the top of the chassis assembly 1. The flip frames 301 are symmetrically screwed to the inner surface of the top of the chassis assembly 1 via flip shafts 306. The outer top of each set of flip frames 301 is fixed with a dynamic ring rail 303. Each set of flip shafts 306 is fixed with a pair of synchronous gears 307. The flip shafts 306 installed on the same side of different flip shafts 306 are meshed and connected. One set of flip frames 301 can rotate automatically, forming a synchronous flipping action of the two sets of flip frames 301.

[0048] The movable frame 401 can slide along the fixed ring rail 202 and the dynamic ring rail 303, and the surrounding laser scanning probe 407 is installed on the inner side of the top of the movable frame 401. A fixed straight rail 502 is symmetrically fixed on one side of the top of the base frame assembly 1. The two sides of the bottom end of the translation frame 503 are respectively slidably connected with different fixed straight rails 502. The auxiliary laser scanning probe 506 is installed in the inner middle part of the top of the translation frame 503. The outer top side of each group of flip frames 301 is fixed with a dynamic straight rail 510, and after the flip frame 301 is flipped upward into place, the dynamic ring rail 303 can form a complete circular structure with the fixed ring rail 202, and the solid straight rail 502 on the same side is aligned and connected with the dynamic straight rail 510, so that the translation frame 503 can enter the sliding connection formed with the dynamic straight rail 510 through the sliding connection formed with the solid straight rail 502;

[0049] Here’s how it works:

[0050] The top middle part of the chassis assembly 1 is used to hoist and place the mold to be scanned and inspected. The purpose of using laser scanning to inspect the mold is to generate a three-dimensional digital model of the mold by laser scanning, which is used to compare with the design, verify the status of the mold, and ensure that the mold meets the requirements of the drawing;

[0051] Before testing, the entire surround scanning assembly 4 needs to be automatically moved to a position where it slides with the dynamic ring rail 303, and the flip frame 301 needs to be flipped down into place. This is to ensure that when the mold is hoisted and placed on the top of the base assembly 1 by the overhead crane, the mold will not touch or damage the surround scanning assembly 4.

[0052] Before testing, the translation frame 503 automatically slides to the starting position at one end of the fixed straight rail 502, which also does not interfere with the hoisting of the mold to be tested;

[0053] After the mold is hoisted and placed in the middle of the top of the base assembly 1, the rotation drive mechanism connected to one of the flip frames 301 is started, driving the flip frame 301 to rotate with the flip axis 306 as the reference, and with the cooperation of the synchronous gear 307 on the same side to form a transmission connection, the two symmetrically distributed flip frames 301 can keep rotating synchronously towards each other. As the two groups of flip frames 301 are flipped up synchronously, after the flip frames 301 are flipped up into place, the dynamic ring rail 303 is aligned and connected with the fixed ring rail 202. The symmetrically distributed dynamic ring rail 303 and the symmetrically distributed fixed ring rail 202 together form a complete circular path, and surround the placed mold.

[0054] The movable frame 401 can automatically move along the movable ring rail 303. After the movable ring rail 303 and the fixed ring rail 202 are aligned and connected, the movable frame 401 can also automatically move along the complete circular path formed by the movable ring rail 303 and the fixed ring rail 202, driving the surrounding laser scanning probe 407 to perform a surrounding scan of the mold, quickly and accurately completing the inspection of the mold shape and size.

[0055] After the flip frame 301 flips upward into position, the fixed straight rail 502 and the movable straight rail 510 on the same side are aligned and connected, so that the fixed straight rail 502 and the movable straight rail 510 can form a linear path for continuous movement, so that the translation frame 503 can not only automatically move along the fixed straight rail 502, but also move from the fixed straight rail 502 to a position where it slides and cooperates with the movable straight rail 510, so that the translation frame 503 can move laterally above the mold, and the auxiliary laser scanning probe 506 and the surrounding laser scanning probe 407 are used to jointly scan and detect the mold. The auxiliary laser scanning probe 506 provides an auxiliary effect on the surrounding laser scanning probe 407, which can improve the detection accuracy of the mold.

[0056] After the mold inspection is completed, when it needs to be hoisted and removed, the translation frame 503 is moved from the transition position with the dynamic straight rail 510 to the position with the fixed straight rail 502, and the movable frame 401 is moved to the position with any set of dynamic ring rails 303, and the flip frame 301 is flipped down into place. The surround scanning assembly 4 is moved to a safe position as a whole along with the flip frame 301, and then the mold that has been inspected can be safely removed.

[0057] The specific structure of the chassis assembly 1 is as follows Figure 2 and Figure 3 As shown, the top of the bottom frame body 102 is welded and fixed to the bottom end of the bottom mounting plate 101, a nylon block 103 is fixedly connected to the middle of the top of the bottom mounting plate 101, and the vertical sliding seat 104 is fixedly installed in the main body of the bottom mounting plate 101 with the nylon block 103 as the center;

[0058] The bottom end of the placement plate 105 is fixed with vertical sliding columns 106 in an arranged manner. The vertical sliding columns 106 on the same side are slidably connected to the vertical sliding seat 104. A buffer spring 108 is sleeved and installed in each group of vertical sliding columns 106. One end of the buffer spring 108 is fixed to the placement plate 105, and the other end is fixed to the bottom mounting plate 101.

[0059] A bottom connecting plate 107 is fixedly connected between the bottom ends of two adjacent groups of vertical sliding columns 106, and the bottom connecting plate 107 does not interfere with the rotation of the flip frame 301 based on the flip axis 306;

[0060] The top of the placement plate 105 is used to place the mold to be tested. Before the mold is placed on the top of the placement plate 105, under the action of the supporting elastic force of the buffer spring 108, there is enough space between the bottom end of the placement plate 105 and the top end of the nylon block 103;

[0061] After the mold is hoisted and dropped to the top of the placement plate 105, its own gravity will make the bottom of the placement plate 105 fit with the top of the nylon block 103, so that the mold is safely placed;

[0062] The buffer spring 108 and the nylon block 103 both provide elastic buffer support for the placement plate 105, reducing the impact of the mold's own weight on the device when it falls.

[0063] In addition, due to the viewing angle and surrounding coverage of the surround-type laser scanning probe 407, the buffer support elasticity of the mold formed by the placement plate 105 and the nylon block 103, the resulting different height references after the mold is placed will not affect the scanning work of the surround-type laser scanning probe 407.

[0064] The specific structure of the fixed ring rail assembly 2 is as follows Figure 4As shown, the top of the bottom mounting plate 101 is symmetrically arranged with the connecting columns 201 around the placement plate 105, and the bottom end of the fixed ring rail 202 is fixedly connected to the top of the connecting column 201 on the same side;

[0065] The fixed ring teeth 203 are fixedly connected to the outer arc surface of the fixed ring rail 202;

[0066] The top of the bottom mounting plate 101 is symmetrically fixed with the placement plate 105 as the center. The nylon protective cover 204 is set at a height higher than the fixed ring rail 202 to protect the fixed ring rail 202 and prevent it from being touched during the mold hoisting process.

[0067] Furthermore, the nylon protective cover 204 will not interfere with the surrounding scanning operation of the surrounding laser scanning probe 407 .

[0068] The specific structure of the dynamic ring rail assembly 3 is as follows Figure 5 、 Figure 6 and Figure 7 As shown, the dynamic ring rail 303 is fixedly connected to the outer top of the flip frame 301 through the dynamic rail connecting column 302, and the dynamic ring gear 304 is fixedly connected to the outer arc surface of the dynamic ring rail 303;

[0069] As the turning frame 301 turns upward into position, the movable ring rail 303 is aligned and connected with the fixed ring rail 202 to form a full circular path. The movable ring gear 304 can also be aligned and connected with the fixed ring gear 203 to form a complete gear structure.

[0070] A flip seat 305 is symmetrically fixedly mounted on the bottom end of the bottom mounting plate 101, and a flip shaft 306 on the same side is rotatably connected to the flip seat 305;

[0071] The vertical rod 308 is vertically fixedly connected between the bottom end of the bottom mounting plate 101 and the inner bottom end of the bottom frame body 102, the electric cylinder fixed rotary seat 309 is fixedly installed on one side of the upper end of the vertical rod 308, and the inner bottom end of the bottom frame body 102 is fixedly installed with a connecting rod bottom rotary seat 310. A connecting shaft 314 is fixedly connected transversely to the inner frame of one group of the flip frames 301. One end of the driving connecting rod 311 is rotationally connected to the connecting rod bottom rotary seat 310, and the other end is rotationally connected to the connecting connecting rod 315. The other end of the connecting connecting rod 315 is rotationally connected to the connecting shaft 314. The middle part of the main body of the driving connecting rod 311 is transversely fixedly connected to the driving rotary shaft 312. The main body of the driving electric cylinder 313 is rotationally connected to the electric cylinder fixed rotary seat 309, and the telescopic rod head end of the driving electric cylinder 313 is rotationally connected to the driving rotary shaft 312.

[0072] The movement of the telescopic rod of the driving electric cylinder 313 and the rotational connection formed with the driving rotary shaft 312 can drive the driving connecting rod 311 to rotate with the connecting rod base rotary seat 310 as the reference. Since the distance between the flip axis 306 and the connecting shaft 314 is fixed, when the driving connecting rod 311 rotates, the connecting rod 315 screwed between the connecting shaft 314 and the driving connecting rod 311 can be used to drive one group of flip frames 301 to form a flip movement with the flip axis 306 as the reference. Combined with the meshing action formed by the synchronous gear 307, the two symmetrically distributed groups of flip frames 301 can form a synchronous flip movement.

[0073] The specific structure of the surround scanning component 4 is as follows Figure 8 As shown, a pair of inwardly rotating rollers 402 are rotatably connected to the inner side of the bottom end of the main body of the movable frame 401, and a pair of outwardly rotating rollers 403 are rotatably connected to the outer side of the bottom end of the main body of the movable frame 401. The inwardly rotating rollers 402 are in rolling connection with the guide grooves in the inner arc surfaces of the fixed ring rail 202 and the movable ring rail 303, and the outwardly rotating rollers 403 are in rolling connection with the guide grooves in the outer arc surfaces of the fixed ring rail 202 and the movable ring rail 303, so that the movable frame 401 can move along the path formed by the fixed ring rail 202 and the movable ring rail 303.

[0074] A moving motor 404 is fixedly mounted on the top of the moving frame 401. The rotating shaft of the moving motor 404 passes through the main body of the moving frame 401 and is fixedly connected to the moving gear 405. The moving gear 405 can form a meshing transmission with the fixed ring gear 203 or the movable ring gear 304.

[0075] After the movement motor 404 stops rotating, the movement gear 405 can be stopped, so that the moving frame 401 is maintained in position along the fixed ring rail 202 or the moving ring rail 303;

[0076] The top of the movable frame 401 is fixedly connected to the vertical frame 406, and the surround-type laser scanning probe 407 is installed and fixed on the inner side of the top of the vertical frame 406. The vertical frame 406 has a certain inward tilt angle, which is used to adjust the viewing angle of the surround-type laser scanning probe 407, so that the surround-type laser scanning probe 407 can scan and detect the mold more accurately and comprehensively.

[0077] The specific structure of the auxiliary scanning component 5 is as follows Figure 9 and Figure 10 As shown, the outer frame 501 is symmetrically fixedly connected to one side of the top of the bottom mounting plate 101, the fixed straight rail 502 and the fixed rack 507 are fixedly connected to the upper end of the outer surface of the outer frame 501, and the translation frame 503 is slidably connected to the fixed straight rail 502 through the translation slide rail 504 at the bottom end;

[0078] The outer top end of the side of each set of outer frames 501 is fixedly connected with an outer limit plate 505 to prevent the translation rail 504 from slipping off one end of the fixed straight rail 502;

[0079] The movable rack 511 is installed parallel to the movable straight rail 510 on the side of the outer top of the turning frame 301;

[0080] A translation motor 508 is mounted on both sides of the lower end of the outer side of the translation frame 503. A translation gear 509 is inserted and fixed in the rotating shaft of the translation motor 508 and meshes with the fixed rack 507 or the movable rack 511.

[0081] Similarly, after stopping the rotation of the translation motor 508, the translation gear 509 can be stopped, so that the translation frame 503 is maintained in position along the fixed straight rail 502 or the movable straight rail 510;

[0082] When the turning frame 301 is turned upwards and in place, the movable straight rail 510 is aligned and connected to the fixed straight rail 502, and the movable rack 511 on the same side is aligned and connected to the fixed rack 507 to form a complete rack path;

[0083] The two sets of translation motors 508 are started synchronously to drive the rotation of the translation gear 509. Through the coordinated transmission formed by the translation gear 509 and the fixed rack 507 or the movable rack 511, the translation frame 503 can be driven to automatically move guided by the sliding cooperation formed by the translation slide 504 and the fixed straight rail 502 or the sliding cooperation formed by the translation slide 504 and the movable straight rail 510, thereby realizing the position change of the auxiliary laser scanning probe 506.

[0084] It can not only limit the other end of the solid straight rail 502, but also can separate the safety limit seat member 6 from the limit work of the other end of the solid straight rail 502 during the process of the flip frame 301 turning over. Figure 11 and Figure 12 As shown, the elastic seats 601 are symmetrically fixedly connected to the top of the bottom mounting plate 101, and each group of elastic seats 601 is slidably connected to a pair of elastic slide posts 602, the passive limit plate 603 is fixedly connected to one end of the elastic slide post 602 on the same side, and the inner connecting seat 605 is fixedly connected to the other end of the elastic slide post 602 on the same side. A compression spring 604 is sleeved and installed in each group of elastic slide posts 602, and one end of the compression spring 604 is clamped to the passive limit plate 603, and the other end is clamped to the elastic seat 601;

[0085] Under the supporting elastic force formed by the compression spring 604, when there is no external force pushing the passive limit plate 603, the passive limit plate 603 can be naturally extended, forming a limiting effect on the other end of the solid straight rail 502, so that in the non-detection state, the translation frame 503 can safely stay in the position of sliding connection with the solid straight rail 502;

[0086] A passive arc surface 606 is formed on the outer side of the bottom end of the passive limiting plate 603, and a pushing arc surface 607 is formed on the inner side of the top end of the flip frame 301. When the flip frame 301 flips upward to a certain position, the pushing arc surface 607 can form a contact and tangent fit with the passive arc surface 606. As the flip frame 301 continues to flip upward, the contact and tangent fit formed by the pushing arc surface 607 and the passive limiting plate 603 can push the passive limiting plate 603 to move closer to the side of the elastic seat 601.

[0087] Before the movable straight rail 510 is aligned and connected with the fixed straight rail 502, the passive limit plate 603 has been pushed away to a position where it cannot form a limit on the fixed straight rail 502 and the fixed rack 507, so as to facilitate the alignment and connection of the movable straight rail 510 with the fixed straight rail 502 and the alignment and connection of the movable rack 511 with the fixed rack 507 after the subsequent flip frame 301 is flipped upward into place.

[0088] Preferably, a calibration reference 7 is further provided on the side of the placement plate 105, which can realize the position recognition and precision correction of the surround scanning component 4. The reference inclined surfaces 701 are provided on different sides of the placement plate 105, and the reference graphics 702 of different shapes are respectively provided in different reference inclined surfaces 701. The purpose of setting the reference inclined surfaces 701 as inclined surfaces is to make it easier for the surround laser scanning probe 407 to recognize them. Since the reference graphics 702 provided in each group of reference inclined surfaces 701 are different and of standard size, it can be made that only the surround laser scanning probe 407 Only when the movable frame 401 moves to the fixed ring rail 202 or the movable ring rail 303 on the current side can the corresponding reference figure 702 be identified, so that the reference figure 702 can be used to guide the movable frame 401 to confirm its stop position on the fixed ring rail 202 or the movable ring rail 303, so as to ensure that when the flip frame 301 flips, the surrounding scanning component 4 as a whole is in a safe position for sliding cooperation with the movable ring rail 303; on the other hand, since the reference figure 702 is a figure with standard shape and depth, the scanning accuracy of the surrounding laser scanning probe 407 can also be corrected using the reference figure 702.
