Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, the present invention provides a device for detecting the wear degree of a mold, comprising a support frame 1, a driving screw 2 is rotatably connected to the front side of the top of the support frame 1, a fixing rod 3 is fixedly installed on the rear side of the top of the support frame 1, a sliding sleeve 30 is movably sleeved on the surface of the fixing rod 3, a meshing ring 5 is meshed on the surface of the driving screw 2, a connecting shaft 24 is fixedly installed on both the front and rear ends of the meshing ring 5, a laser scanner 6 is provided between the sliding sleeve 30 and the meshing ring 5, a mounting frame 7 is fixedly installed on the surface of the two connecting shafts 24, a roller brush 8 is rotatably connected to the bottom end of the mounting frame 7, and the roller brush 8 is provided with longer fluff to facilitate dealing with the unevenness on the mold, and the longer fluff is provided so that when the roller brush 8 rotates counterclockwise, the axis of the roller brush 8 will not contact and interfere with the mold;

[0031] The top of the sliding sleeve 30 is rotatably connected with a gear 1 9, the front end of the gear 1 9 is fixedly installed with a gear 2 10, the surface of the rear end connecting shaft 24 is rotatably connected with a transmission gear ring 11, the right end of the rear end mounting frame 7 is rotatably connected with a gear 3 13, the front end of the gear 3 13 and the rear end of the roller brush 8 are both fixedly installed with a transmission wheel 14, and the surface of the transmission wheel 14 is sleeved with a transmission belt 15;

[0032] By arranging a gear 9 meshing with the driving rack 12 on the sliding sleeve 30, the gear 9 can be driven to rotate through the movement of the laser scanner 6, and then the transmission gear ring 11 is driven to rotate through the gear 2 10, and then the transmission wheel 14 is driven to rotate through the gear 3 13 and the transmission belt 15, and then the roller brush 8 is driven to rotate on the top surface of the lower mold 33 or the bottom surface of the upper mold, and the scanning surfaces of the lower mold 33 and the upper mold are pre-cleaned, so that the laser scanner 6 can automatically clean the scanning position while moving and scanning, thereby shortening the detection time and improving the detection efficiency.

[0033] Among them, a fixed air pipe 16 is fixedly installed on the left side of the laser scanner 6, and the inner cavity of the fixed air pipe 16 is rotatably connected to a fan group 17, and a transmission wheel 2 32 is fixedly installed at the rear end of the fan group 17, and the transmission wheel 2 32 is sleeved in the transmission belt 15. A connecting pipe 18 is fixedly installed at the front end of the fixed air pipe 16, and an air outlet pipe 19 is fixedly installed at the bottom end of the connecting pipe 18;

[0034] When the roller brush 8 is driven to rotate for cleaning when the laser scanner 6 moves and scans, the transmission wheel 2 32 is driven to rotate through the transmission belt 15, thereby driving the fan group 17 to rotate in the fixed air pipe 16, and the outside air is drawn into the fixed air pipe 16, and then enters the connecting pipe 18 and the outlet pipe 19 through the fixed air pipe 16, and finally blows to the bottom surface of the laser scanner 6 through the outlet pipe 19, so that the bottom end of the laser scanner 6 is continuously blown to drive the nearby air flow during the scanning process, thereby avoiding dust adhering to the bottom end of the laser scanner 6 to block the laser, thereby improving the accuracy of detection.

[0035] The shape of the air outlet pipe 19 is J-shaped, and the bottom outlet direction of the air outlet pipe 19 is toward the bottom end of the laser scanner 6;

[0036] The J-shaped air outlet pipe 19 can ensure that the air blown out of the air outlet pipe 19 can be located below the laser scanner 6 , thereby driving the air flow below the laser scanner 6 .

[0037] Among them, the unlocking magnetic strip 20 and the steering rack 21 are fixedly installed on the left and right sides of the top of the front side of the support frame 1, the meshing ring 5 and the end of the sliding sleeve 30 close to the laser scanner 6 are fixedly installed with the support sleeve 22, the inner cavity of the support sleeve 22 is provided with a lock hole 23, the surface of the front connecting shaft 24 is fixedly installed with a fixing ring 31, the upper and lower ends of the fixing ring 31 are movably connected with a locking pin 26, the end of the locking pin 26 close to the laser scanner 6 is fixedly installed with a return spring 25, the surface of the front connecting shaft 24 is fixedly installed with a steering gear ring 27, and the rear connecting shaft 24 is movably connected with the sliding sleeve 30;

[0038] A locking pin 26 is provided at the connection position of the connecting shaft 24 and the meshing ring 5 to connect the two. When the laser scanner 6 moves to the leftmost and rightmost sides, the locking pin 26 is driven to move by the support sleeve 22, thereby unlocking the meshing ring 5 and the connecting shaft 24. The meshing of the steering gear ring 27 with the steering rack 21 can drive the laser scanner 6 to rotate 180 degrees counterclockwise, thereby automatically adjusting the direction of the scanning surface of the laser scanner 6, so that the upper mold can be automatically scanned after the lower mold is scanned, and there is no need to move the device during the process, and there is no need to re-center when scanning the upper mold. The operation is simple and convenient. After the laser scanner 6 completes the scanning of the lower mold, the steering gear ring 27 can be engaged with the steering rack 21 to automatically drive the laser scanner 6 to rotate 180 degrees. At this time, it is only necessary to adjust the height of the upper mold so that the upper mold contacts the roller brush 8 to realize the scanning and detection of the upper mold. The entire detection process does not require the mold to be removed from the equipment for separate detection, and after the detection is completed, the mold can directly continue the production task.

[0039] The connecting shaft 24 is sleeved in the supporting sleeve 22, the supporting sleeve 22 and the connecting shaft 24 are in close contact, and the locking pin 26 is inserted in the locking hole 23;

[0040] When the laser scanner 6 moves for scanning and detection, the locking pin 26 is inserted into the locking hole 23, thereby connecting the connecting shaft 24 and the meshing ring 5 to avoid angular deviation when the laser scanner 6 moves. The close contact between the support sleeve 22 and the connecting shaft 24 can ensure that when the locking pin 26 unlocks the connecting shaft 24 and the meshing ring 5, the movement of the roller brush 8 will not drive the laser scanner 6 to rotate directly.

[0041] The steering rack 21 on the left side of the support frame 1 is located below the steering gear ring 27, and the steering rack 21 on the right side of the support frame 1 is located above the steering gear ring 27;

[0042] Two steering racks 21 distributed up and down are provided to control the laser scanner 6 to rotate counterclockwise, and the top end of the right side of the support frame 1 is open to provide space for the overall rotation of the laser scanner 6 and the roller brush 8 to avoid interference.

[0043] There are two unlocking magnetic stripes 20, which are respectively located on the upper and lower sides of the front connecting shaft 24, and both unlocking magnetic stripes 20 are located on the side of the fixing ring 31 close to the laser scanner 6;

[0044] An unlocking magnetic strip 20 with magnetic attraction is provided, and the lock pin 26 is separated and unlocked from the lock hole 23 by the magnetism of the unlocking magnetic strip 20. When the gear 9 moves in the reverse direction to the driving rack 12, the magnetic force of the unlocking magnetic strip 20 stops adsorbing the lock pin 26, and the return spring 25 in a compressed state can provide elastic force for the lock pin 26, thereby allowing the lock pin 26 to be inserted into the lock hole 23 for locking.

[0045] Among them, the right side of the support frame 1 is rotatably connected with an adjustable bidirectional lead screw 28, and the front and rear ends of the adjustable bidirectional lead screw 28 are meshed with positioning plates 29. A handle is fixedly installed on the front side of the adjustable bidirectional lead screw 28, and the positioning plate 29 is movably connected to the support frame 1. The middle part of the adjustable bidirectional lead screw 28 is movably connected to the middle part of the right side of the support frame 1, and the threads of the front and rear sides of the adjustable bidirectional lead screw 28 rotate in opposite directions;

[0046] Place the support frame 1 on the mounting seat 34, then rotate and adjust the handle on the front side of the bidirectional lead screw 28, and by adjusting the engagement between the bidirectional lead screw 28 and the positioning plate 29, the positioning plate 29 can be driven to move toward the support frame 1. Figure 8 As shown, after contacting the side of the mounting seat 34, the positioning plate 29 cannot move further. At this time, the center of the support frame 1 is located on the center line of the lower mold 33, realizing a rapid centering operation of the device and the mold.

[0047] The transmission gear ring 11 is meshed with both the gear 2 10 and the gear 3 13, and the gear 3 13 is located at the front side of the gear 2 10;

[0048] Gear three 13 is arranged to be placed in front of gear two 10 to avoid interference between gear three 13 and gear two 10 when the bottom surface of the laser scanner 6 rotates upward, and retaining rings are arranged on the left and right sides of the transmission gear ring 11 on the connecting shaft 24 to avoid movement of the position of the transmission gear ring 11 and ensure smooth rotation of the transmission gear ring 11 on the connecting shaft 24.

[0049] Among them, the top end of the fixing rod 3 is provided with deep grooves at the positions on the left and right sides of the driving rack 12;

[0050] By setting the deep groove, when gear 1 9 leaves the driving rack 12, it will enter the deep groove. At this time, gear 1 9 will not rotate, and the laser scanner 6 has completed the scanning to ensure that gear 3 13 can run smoothly when it rotates to above the transmission gear ring 11.

[0051] The working principle and use process of the present invention:

[0052] When in use, the support frame 1 is placed on the mounting seat 34, and then the handle on the front side of the bidirectional lead screw 28 is rotated to adjust the engagement between the bidirectional lead screw 28 and the positioning plate 29, so that the positioning plate 29 can be driven to move toward the support frame 1. Figure 8 As shown, after contacting the side of the mounting seat 34, the positioning plate 29 cannot move further, and the center of the support frame 1 is located on the center line of the lower mold 33;

[0053] Then, the servo motor 4 is started, and the servo motor 4 drives the driving screw 2 to rotate, and then drives the laser scanner 6 to move left through the engagement with the meshing ring 5. When the laser scanner 6 moves, it drives the gear 1 9 on the sliding sleeve 30 to move on the driving rack 12, and then drives the gear 1 9 to rotate, and then drives the gear 2 10 to rotate. Through the engagement of the transmission gear ring 11 with the gear 2 10 and the gear 3 13, the gear 3 13 and the transmission wheel 14 can be driven to rotate, and the roller brush 8 and the fan group 17 are driven to rotate through the transmission belt 15. When the fan group 17 rotates, it can draw in external air from the rear side of the fixed air pipe 16, and transport it to the air outlet pipe 19 through the connecting pipe 18, and blow it to the bottom of the laser scanner 6 through the air outlet pipe 19. When the roller brush 8 rotates, it can clean the residue on the surface of the lower mold 33 through the contact between the roller brush 8 and the top surface of the lower mold 33. As the laser scanner 6 continues to move left, the residue can be cleaned to the left side of the scanning position before the laser scanner 6 scans.

[0054] When the laser scanner 6 moves to the left, the top surface of the lower mold 33 can be laser scanned, thereby generating a spacing value between each location of the top surface of the lower mold 33 and the laser scanner 6, and comparing this spacing value with the spacing value of the unworn mold, the difference obtained is the wear degree;

[0055] When the laser scanner 6 moves to the left and the gear 1 9 is in the deep groove on the left, the gear 1 9 stops rotating. At this time, the unlocking magnetic strip 20 is located directly behind the lock pin 26. The lock pin 26 moves backward and leaves the lock hole 23 through the magnetic force of the unlocking magnetic strip 20. At the same time, the bottom end of the steering gear ring 27 meshes with the steering rack 21 on the left. Then, as the laser scanner 6 moves, the laser scanner 6 and the roller brush 8 can be driven to rotate counterclockwise as a whole, so that the top surface of the laser scanner 6 faces upward. At this time, the gear 3 13 rotates to the top of the transmission gear ring 11 and continues to mesh with the transmission gear ring 11.

[0056] Then the servo motor 4 reverses and drives the laser scanner 6 to move rightward. Similarly, the roller brush 8 contacts the upper mold in advance and cleans the scanning position of the upper mold. By moving the laser scanner 6 rightward, the upper mold can be scanned to obtain the wear degree of the upper mold.

[0057] When the laser scanner 6 moves to the right and the gear 9 is in the deep groove on the right, the locking pin 26 moves backward again to unlock the connecting shaft 24 and the meshing ring 5. At this time, the top of the steering gear ring 27 is engaged with the right steering rack 21, which can drive the laser scanner 6 and the roller brush 8 to continue to rotate counterclockwise one hundred and eighty degrees as a whole, thereby making the bottom surface of the laser scanner 6 face downward.
