Description

Technical Field

[0001] The present invention relates to the technical field of mold inspection tools, and particularly relates to a laser scanner-assisted workbench for manufacturing motorcycle body panel molds. Background Art

[0002] Motorcycle body panels (also known as motorcycle shells or exterior trim parts) are important components installed outside the frame, mainly used for functional protection and appearance beautification; most of them are composed of plastic parts and have complex curved surfaces, requiring injection molding. Therefore, the manufacturing quality of injection molds directly affects the overall functionality and appearance beauty of the motorcycle after assembly.

[0003] The existing dimensional and shape inspections of motorcycle injection molds still mainly rely on manual inspection tools, which have the following disadvantages:

[0004] 1. Low inspection efficiency. Manual inspection is slow, and multiple key dimensions of the body panel need to be measured one by one, making it difficult to meet the requirements of mass production and unable to adapt to the high-efficiency production rhythm of the modern injection molding industry.

[0005] 2. The inspection accuracy is greatly affected by subjective factors. Manual inspection depends on the experience, eyesight status, and fatigue level of the operator, which may lead to misjudgment or missed inspection.

[0006] 3. Poor inspection consistency and difficulty in standardization. Different quality inspectors may have inconsistent judgment criteria for the same product, resulting in quality fluctuations.

[0007] 4. Unable to comprehensively cover the inspection of complex curved surfaces. Motorcycle body panels usually have complex curved surfaces (such as streamlined shells), and it is difficult for manual inspection tools to accurately measure the deviations of free-form surfaces. Summary of the Invention

[0008] The purpose of the present invention is to provide a laser scanner-assisted workbench for manufacturing motorcycle body panel molds. By cooperating with the flipping action of the flipping frame, the moving circular rail and the fixed circular rail can form an integral circular path, and the moving linear rail and the fixed linear rail are aligned and connected. It can not only achieve the purpose of installing, hoisting, and placing the mold, but also use the cooperation of the surrounding scanning component and the secondary scanning component to comprehensively and accurately perform the scanning and inspection work on the mold.

[0009] The purpose of the present invention is achieved through the following technical solution: A laser scanner-assisted workbench for manufacturing motorcycle body panel molds includes a chassis component, a fixed circular rail component, a moving circular rail component, a surrounding scanning component, and a secondary scanning component. The fixed circular rail component includes a fixed circular rail, the moving circular rail component includes a flipping frame and a flipping shaft, the surrounding scanning component includes a moving frame and a surrounding laser scanning probe, and the secondary scanning component includes a translation frame and a secondary laser scanning probe.

[0010] The fixed ring track is symmetrically fixed at the top of the chassis assembly. The flipping frame is symmetrically rotatably connected to the inner surface at the top of the chassis assembly through a flipping shaft. A moving ring track is fixed to the outer top end of each group of flipping frames. Synchronous gears are fixedly paired in each group of flipping shafts, and the flipping shafts on the same side are meshed and connected.

[0011] The moving frame can slide along the fixed ring track and the moving ring track. The circumferential laser scanning probe is installed on the inner side of the top end of the moving frame. Fixed straight tracks are symmetrically fixed on one side of the top end of the chassis assembly. The two sides of the bottom end of the translation frame are respectively slidably connected to different fixed straight tracks. The auxiliary laser scanning probe is installed in the middle of the inner part of the top end of the translation frame. A moving straight track is fixed to the outer top side of each group of flipping frames. After the flipping frame is flipped upwards in place, the moving ring track can form a complete circular ring structure with the fixed ring track, and the fixed straight track and the moving straight track on the same side are aligned and connected.

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

[0013] The middle of the top end of the chassis assembly is used to place the mold to be scanned and detected.

[0014] Before detection, the circumferential scanning assembly needs to be automatically moved as a whole to a position slidably engaged with the moving ring track, and the flipping frame is flipped downwards in place.

[0015] Before detection, the translation frame automatically slides to the starting position at one end of the fixed straight track.

[0016] After the mold is hoisted and placed in the middle of the top end of the chassis assembly, the rotation drive mechanism connected to one group of flipping frames is started to drive the flipping frame to rotate with the flipping shaft as the reference. With the cooperation of the transmission connection formed by the synchronous gears on the same side, the two symmetrically distributed flipping frames can be kept in a state of synchronously rotating towards each other. With the synchronous upward flipping action of the two groups of flipping frames, after the flipping frame is flipped upwards in place, the moving ring track and the fixed ring track are aligned and connected, and the symmetrically distributed moving ring track and the symmetrically distributed fixed ring track jointly form a complete circular path.

[0017] The moving frame can not only automatically move along the moving ring track, but also automatically move along the complete circular path formed by the moving ring track and the fixed ring track after the moving ring track and the fixed ring track are aligned and connected, driving the circumferential laser scanning probe to perform circumferential scanning work on the mold.

[0018] After the flipping frame is flipped upwards in place, the fixed straight track and the moving straight track on the same side are aligned and connected, enabling the translation frame to not only automatically move along the fixed straight track, but also move from the fixed straight track to a position slidably engaged with the moving straight track, so that the translation frame moves horizontally above the mold, and the auxiliary laser scanning probe and the circumferential laser scanning probe cooperate to jointly perform scanning and detection work on 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 flip frame that is symmetrically distributed and can be synchronously flipped to separate and combine the moving ring track and the fixed ring track. After the overall circumferential scanning assembly moves to a position where it cooperates with the moving ring track, as the flip frame flips downward in place, the circumferential scanning assembly can be placed in a relatively safe position relative to the mold detection placement position, protecting the circumferential laser scanning probe from being affected by the mold hoisting.

[0021] (2) After the flip frame flips upward in place, the symmetrically distributed moving ring track and the symmetrically distributed fixed ring track can form a complete circular ring structure, providing a path for the circumferential scanning assembly to move circumferentially along the mold.

[0022] (3) After the flip frame flips upward in place, the moving straight track fixed on the outer top side of the flip frame aligns and connects with the fixed straight track at a fixed position, enabling the translation frame to enter a state of sliding cooperation with the moving straight track from a state of sliding cooperation with the fixed straight track. On the basis of the circumferential laser scanning probe scanning and detecting the mold, with the assistance of the auxiliary laser scanning probe, the mold can be scanned and detected comprehensively and accurately.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0046] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "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 invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0047] As Figures 1 - 13 shown, a laser scanner-assisted workbench for manufacturing a motorcycle cover mold, fixed rings 202 are symmetrically fixed at the top of the chassis assembly 1. The flip frames 301 are symmetrically rotatably connected to the inner surface of the top of the chassis assembly 1 through the rotation shafts 306. Moving rings 303 are fixed to the outer tops of each group of flip frames 301. Synchronous gears 307 are fixedly paired in each group of rotation shafts 306, and the rotation shafts 306 on the same side installed in different rotation shafts 306 are meshed and connected. One group of flip frames 301 can rotate automatically, and a synchronous flipping action of the two groups of flip frames 301 can be formed;

[0048] The moving frame 401 can slide along the fixed ring 202 and the moving ring 303. The circumferential laser scanning probe 407 is installed on the inner side of the top of the moving frame 401. Fixed vertical rails 502 are symmetrically fixed on one side of the top of the chassis assembly 1. The bottom ends of both sides of the translation frame 503 are respectively slidably connected to different fixed vertical rails 502. The secondary laser scanning probe 506 is installed in the middle of the top of the translation frame 503. Moving vertical rails 510 are fixed to the outer top sides of each group of flip frames 301. After the flip frames 301 are flipped upward in place, the moving ring 303 can form a complete circular ring structure with the fixed ring 202, and the fixed vertical rails 502 on the same side are aligned and connected to the moving vertical rails 510, so that the translation frame 503 can enter the sliding connection formed with the moving vertical rails 510 through the sliding connection formed with the fixed vertical rails 502;

[0049] The working principle is as follows:

[0050] The middle part of the top end of the chassis assembly 1 is used for hoisting and placing the mold to be scanned and detected. The purpose of using laser scanning to detect the mold is that laser scanning can generate a three-dimensional digital model of the mold, 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 the detection, it is necessary to automatically move the entire circumferential scanning assembly 4 to a position where it is slidably engaged with the moving ring rail 303, and turn the flipping frame 301 downward in place. The purpose is to ensure that during the process of hoisting and placing the mold on the top end of the chassis assembly 1 by the overhead crane, the mold will not touch or damage the circumferential scanning assembly 4;

[0052] And before the detection, the translation frame 503 automatically slides to the starting position at one end of the fixed straight rail 502, and similarly will not interfere with the hoisting of the mold to be detected;

[0053] After the mold is hoisted and placed in the middle of the top end of the chassis assembly 1, the rotation drive mechanism connected to one of the flipping frames 301 is started, driving the flipping frame 301 to rotate with the rotation axis 306 as the reference. Under the cooperation of the transmission connection formed by the synchronous gears 307 on the same side, the two symmetrically distributed flipping frames 301 can be kept in a state of synchronous opposite rotation. As the two flipping frames 301 synchronously turn upward, after the flipping frame 301 turns upward in place, the moving ring rail 303 is aligned and connected with the fixed ring rail 202. The symmetrically distributed moving ring rail 303 and the symmetrically distributed fixed ring rail 202 together form a complete circular path, and the placed mold is surrounded by it;

[0054] The moving frame 401 can not only automatically move along the moving ring rail 303. After the moving ring rail 303 is aligned and connected with the fixed ring rail 202, the moving frame 401 can also automatically move along the complete circular path formed by the moving ring rail 303 and the fixed ring rail 202, driving the circumferential laser scanning probe 407 to perform circumferential scanning work on the mold, and quickly and accurately completing the detection work of the shape and size of the mold;

[0055] And after the flipping frame 301 turns upward in place, the fixed straight rail 502 on the same side is aligned and connected with the moving straight rail 510, enabling the fixed straight rail 502 and the moving straight rail 510 to form a continuous moving straight path, 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 is slidably engaged with the moving straight rail 510, so that the translation frame 503 moves horizontally above the mold. The auxiliary laser scanning probe 506 and the circumferential laser scanning probe 407 cooperate to jointly perform scanning and detection work on the mold. Through the auxiliary effect of the auxiliary laser scanning probe 506 on the circumferential laser scanning probe 407, the detection accuracy of the mold can be improved;

[0056] After the mold inspection is completed and it needs to be lifted and removed, when the translation frame 503 is moved from the mating transition with the moving straight rail 510 to the position mating with the fixed straight rail 502, and the moving frame 401 is moved to the position mating with any set of moving ring rails 303, the flipping frame 301 is flipped down in place, and the overall circumferential scanning assembly 4 moves to a safe position along with the flipping frame 301. Subsequently, the inspected mold can be safely removed.

[0057] The specific structure of the chassis assembly 1 is as Figure 2 and Figure 3 shown. The top end of the chassis body 102 is fixedly welded to the bottom end of the bottom mounting plate 101. In the middle of the top end of the bottom mounting plate 101, a nylon block 103 is fixedly connected. The vertical sliding seats 104 are arranged and fixed around the nylon block 103 in the main body of the bottom mounting plate 101;

[0058] Vertically sliding columns 106 are fixedly arranged at the bottom end of the placement plate 105. The vertically sliding columns 106 on the same side are slidably connected to the vertical sliding seats 104. A buffer spring 108 is sleeved and installed in each group of vertically sliding columns 106. One end of the buffer spring 108 is clamped to the placement plate 105, and the other end is clamped to the bottom mounting plate 101;

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

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

[0061] After the mold is lifted and dropped onto the top end of the placement plate 105, its own gravity will cause the bottom end of the placement plate 105 to fit against the top end of the nylon block 103, ensuring the safe placement of the mold;

[0062] The functions of the buffer spring 108 and the nylon block 103 are to provide elastic buffer support force for the placement plate 105, reducing the impact of the mold's own weight on the device at the moment of dropping;

[0063] And due to the viewing angle and circumferential coverage range set by the circumferential laser scanning probe 407, the elastic buffer support for the mold formed by the placement plate 105 and the nylon block 103, which causes the situation of inconsistent height benchmarks after the mold is placed, will not affect the scanning work of the circumferential laser scanning probe 407.

[0064] The specific structure of the fixed ring rail assembly 2 is as Figure 4As shown, connecting columns 201 are symmetrically arranged and fixed at the top end of the bottom mounting plate 101 with the placement plate 105 as the center. The bottom end of the fixed ring rail 202 is fixedly connected to the top end 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] Nylon protective sleeves 204 are also symmetrically fixedly installed at the top end of the bottom mounting plate 101 with the placement plate 105 as the center. And the installation height of the nylon protective sleeves 204 is higher than that of the fixed ring rail 202. The purpose is to form a protection for the fixed ring rail 202 to prevent it from being touched during the hoisting of the mold.

[0067] And the nylon protective sleeves 204 will not interfere with the circumferential scanning work of the circumferential laser scanning probe 407.

[0068] The specific structure of the moving ring rail assembly 3 is as shown in Figure 5 、 Figure 6 and Figure 7 As shown, the moving ring rail 303 is fixedly connected to the outer top end of the flipping frame 301 through the moving rail connecting column 302. The moving ring teeth 304 are fixedly connected to the outer arc surface of the moving ring rail 303.

[0069] And as the flipping frame 301 flips upward to the in-place position, when the moving ring rail 303 aligns and connects with the fixed ring rail 202 to form a complete circular path, the moving ring teeth 304 can also align and connect with the fixed ring teeth 203 to form a complete gear structure.

[0070] Flipping rotating seats 305 are symmetrically fixedly installed at the bottom end of the bottom mounting plate 101. The flipping shaft 306 on the same side is rotatably connected to the flipping rotating 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 rotating seat 309 is fixedly installed on one side of the upper end of the vertical rod 308. The connecting rod bottom rotating seat 310 is fixedly installed at the inner bottom end of the bottom frame body 102. A connecting shaft 314 is horizontally fixedly connected in the inner frame of one group of flipping frames 301. One end of the driving connecting rod 311 is rotatably connected to the connecting rod bottom rotating seat 310, the other end is rotatably connected to the connecting link 315. The other end of the connecting link 315 is rotatably connected to the connecting shaft 314. A driving rotating shaft 312 is horizontally fixedly connected to the middle part of the main body of the driving connecting rod 311. The main body of the driving electric cylinder 313 is rotatably connected to the electric cylinder fixed rotating seat 309. The telescopic rod head end of the driving electric cylinder 313 is rotatably connected to the driving rotating shaft 312.

[0072] The movement of the telescopic rod of the driving electric cylinder 313 and the rotary connection formed with the driving rotary shaft 312 can drive the driving connecting rod 311 to rotate with the bottom rotary seat 310 of the connecting rod as the reference. Since the distance between the turning shaft 306 and the connecting shaft 314 is fixed, when the driving connecting rod 311 rotates, the connecting link 315 sleeved between the connecting shaft 314 and the driving connecting rod 311 can drive one set of turning frames 301 to form a turning action with the turning shaft 306 as the reference, and cooperate with the meshing action formed by the synchronous gear 307, so that the two symmetrically distributed turning frames 301 can form a synchronous turning action.

[0073] The specific structure of the circumferential scanning assembly 4 is as Figure 8 shown. Inside the bottom end of the main body of the moving frame 401, inner rotating rollers 402 are rotatably connected in pairs, and outside the bottom end of the main body of the moving frame 401, outer rotating rollers 403 are rotatably connected in pairs. The inner rotating rollers 402 are in rolling connection with the guide grooves in the inner arc surfaces of the fixed ring rail 202 and the moving ring rail 303, and the outer rotating rollers 403 are in rolling connection with the guide grooves in the outer arc surfaces of the fixed ring rail 202 and the moving ring rail 303, so that the moving frame 401 can move along the path formed by the fixed ring rail 202 and the moving ring rail 303 itself;

[0074] At the top of the moving frame 401, a moving motor 404 is installed and fixed. The rotating shaft of the moving motor 404 passes through the main body of the moving frame 401 and is fixedly connected to a moving gear 405. The moving gear 405 can be in meshing transmission with the fixed ring gear 203 or the moving ring gear 304;

[0075] And after stopping the rotation of the moving motor 404, the rotation of the moving gear 405 can be stopped, so that the moving frame 401 can maintain its position along the fixed ring rail 202 or the moving ring rail 303;

[0076] At the top of the moving frame 401, a vertical frame 406 is fixedly connected. The circumferential laser scanning probe 407 is installed and fixed on the inner side surface of the top of the vertical frame 406, and the vertical frame 406 has a certain angle of inclination towards the inside, which is used to adjust the viewing angle of the circumferential laser scanning probe 407, so that the circumferential laser scanning probe 407 can more accurately and comprehensively scan and detect the mold.

[0077] The specific structure of the secondary scanning assembly 5 is as Figure 9 and Figure 10 shown. The outer frames 501 are 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 both fixedly connected to the upper outer side surface of the outer frame 501. The translation frame 503 is slidably connected to the fixed straight rail 502 through the translation slide rail 504 at the bottom;

[0078] On the outer top side of each side of the outer frame 501, an outer limit plate 505 is fixedly connected to prevent the translation slide rail 504 from slipping off one end of the fixed straight rail 502;

[0079] The moving rack 511 is installed on the side of the outer top end of the flipping frame 301 in parallel with the moving straight rail 510.

[0080] On both sides of the lower end of the outer side of the translation frame 503, translation motors 508 are fixedly installed. The translation gears 509 are inserted and fixed in the rotating shafts of the translation motors 508 and are engaged with the fixed rack 507 or the moving rack 511.

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

[0082] Moreover, after the flipping frame 301 is flipped upward in place and the moving straight rail 510 is aligned and connected with the fixed straight rail 502, the moving rack 511 and the fixed rack 507 on the same side are aligned and connected, forming a complete rack path.

[0083] By synchronously starting the rotation of the two groups of translation motors 508 to drive the translation gears 509, through the cooperative transmission formed by the translation gears 509 and the fixed rack 507 or the moving rack 511, the translation frame 503 can be driven to automatically move with the sliding fit between the translation slide rail 504 and the fixed straight rail 502 or the sliding fit between the translation slide rail 504 and the moving straight rail 510 as the guide, realizing the position transformation of the secondary laser scanning probe 506.

[0084] The safety limit seat member 6 such as Figure 11 and Figure 12 shown can not only limit the other end of the fixed straight rail 502, but also disengage from the limiting work on the other end of the fixed straight rail 502 during the upward flipping process of the flipping frame 301. The elastic seat 601 is symmetrically fixedly connected to the top end of the bottom mounting plate 101. In each group of elastic seats 601, a pair of elastic sliding columns 602 are slidably connected. The passive limiting plate 603 is fixedly connected to one end of the elastic sliding column 602 on the same side, and the inner connecting seat 605 is fixedly connected to the other end of the elastic sliding column 602 on the same side. In each group of elastic sliding columns 602, a compression spring 604 is sleeved and installed. One end of the compression spring 604 is clamped with the passive limiting plate 603, and the other end is clamped with the elastic seat 601.

[0085] Under the action of the supporting elastic force formed by the compression spring 604, when there is no external force to push the passive limiting plate 603, the passive limiting plate 603 can be in a natural outward extension state, forming a limiting effect on the other end of the fixed straight rail 502, so that the translation frame 503 can safely stay at the position where it is slidably connected to the fixed straight rail 502 in the non-detection state.

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

[0087] And before the moving straight rail 510 is aligned and connected with the fixed straight rail 502, the passive limiting plate 603 has been pushed away to a position where it cannot limit the fixed straight rail 502 and the fixed rack 507, which is convenient for the subsequent alignment and connection of the moving straight rail 510 and the fixed straight rail 502 and the alignment and connection of the moving rack 511 and the fixed rack 507 after the flipping frame 301 is flipped upward in place.

[0088] Preferably, a calibration reference 7 is further provided on the side surface of the placement plate 105, which can realize the functions of position recognition and accuracy calibration of the circumferential scanning assembly 4. The reference inclined surface 701 is provided on different side surfaces around the placement plate 105, and different reference patterns 702 of different shapes are respectively provided in different reference inclined surfaces 701. The purpose of setting the reference inclined surface 701 as an inclined surface is to make it more convenient for the circumferential laser scanning probe 407 to identify. Since the reference patterns 702 provided in each group of reference inclined surfaces 701 are different and standard-sized patterns; it can be ensured that only when the circumferential laser scanning probe 407 moves to the current side of the fixed ring rail 202 or the moving ring rail 303 along with the moving frame 401, can the corresponding reference pattern 702 be recognized. Thus, the staying position of the moving frame 401 on the fixed ring rail 202 or the moving ring rail 303 can be confirmed under the guidance of the reference pattern 702, so as to ensure that when the flipping frame 301 flips, the circumferential scanning assembly 4 is in a safe position of sliding cooperation with the moving ring rail 303; on the other hand, since the reference pattern 702 is a pattern with standard shape and depth, the scanning accuracy of the circumferential laser scanning probe 407 can also be calibrated by using the reference pattern 702.

[0089] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
