Description

Technical Field

[0001] This invention relates to the field of bottle cap inspection technology, and in particular to a dual-station alternating bottle cap center deviation detection device and method. Background Technology

[0002] When inspecting the center deviation of bottle caps, our company primarily uses a HEXAGON image measuring instrument for static inspection. Operators place the bottle cap (opening upwards) in the instrument's inspection area, and after inspection, flip it over (opening downwards) for further inspection. After this process, the bottle cap is manually replaced for the next cap. In accordance with industry production quality control standards, 15-25 samples are randomly selected for inspection from each batch of bottle caps produced. This entire process relies on manual loading and unloading, which is cumbersome and inefficient. Furthermore, manual placement of bottle caps cannot guarantee precise alignment between the cap's center and the image measuring instrument's inspection area, resulting in significant placement errors.

[0003] Therefore, a bottle cap center deviation detection fixture was designed. It uses a single set of electric grippers to clamp the bottle caps in the clamping area to the detection area for frontal detection. After frontal detection, the outer wall is rotated 180° for flip detection. After detection, the bottle caps are transported to the unloading area and returned to their original positions before the next bottle cap is clamped and loaded. The single set of electric grippers makes it impossible to perform timely loading and detection of bottle caps after detection, resulting in relatively low overall detection efficiency. Therefore, this application provides a dual-station alternating bottle cap center deviation detection device and method to meet the requirements. Summary of the Invention

[0004] The purpose of this application is to provide a dual-station alternating bottle cap center deviation detection device and method to solve the technical problem that the existing single-set electric gripper operation cannot perform timely loading and detection of bottle caps after the detection is completed, resulting in relatively low overall detection efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a dual-station alternating bottle cap center deviation detection device, comprising a belt conveyor, a bottle cap carrying group installed on the belt conveyor, and a loading and unloading unit;

[0013] As a preferred embodiment of this invention, an installation alignment unit is also provided to achieve precise installation of the device and prevent the bottle cap from being unable to be placed at the center of the detection area due to excessive installation errors.

[0014] As a preferred embodiment of this invention, the mounting alignment unit includes an alignment rack slidably connected to the belt conveyor, a transmission gear rotatably disposed below the belt conveyor, and a toothed plate meshing with the transmission gear.

[0015] The toothed plate is slidably disposed below the belt conveyor, and an L-shaped rod is provided on the outer wall of the toothed plate;

[0016] The transmission gear meshes with the alignment rack, and the alignment end of the alignment rack is configured as a tapered structure.

[0017] One end of the alignment toothed bar slides through the limiting block provided at the bottom of the belt conveyor, and a blocking block is provided at the upper end of the alignment toothed bar. The alignment toothed bar is located in the middle of the two sets of electric grippers.

[0018] The straight-line distance between the alignment end of the alignment rack and the intersection point is D1;

[0019] The straight-line distance between the end of the blocking block near the limiting block and the alignment end of the alignment tooth is D1.

[0020] As a preferred embodiment of this invention, a stabilizing mechanism is also provided to ensure that the belt conveyor operates stably and does not move.

[0021] As a preferred embodiment of this invention, the stabilizing mechanism includes a slider slidably disposed at the bottom of the belt conveyor, a block with two sets of first magnets symmetrically mounted on its upper end, and a square block vertically slidably disposed in the inner cavity of the rotating column.

[0022] The square block is adapted to slide within the cylindrical cavity of the rotating column. Two sets of second magnets are symmetrically arranged in the mounting groove at the lower end of the square block, and the two sets of second magnets correspond one-to-one with the two sets of first magnets, with opposite magnetic poles at opposite ends.

[0023] The lower end of the square block is provided with a movable cavity, and the movable cavity is located below the second magnet. The inner cavity of the movable cavity is provided with a magnetic shielding plate, and the upper end of the magnetic shielding plate is fixed with a column, which is rotatably connected to the square block. The column is provided with a spiral groove.

[0024] One end of the slider is connected to one end of the pull rope, and the other end of the pull rope passes through and extends into the inner cavity of the rotating column and is connected to the movable rod. The lower end of the movable rod extends into the inner cavity of the square block, and the lower end is located in the spiral groove.

[0025] The toothed plate is provided with an abutment rod adapted to the slider at its end;

[0033] In summary, the technical effects and advantages of this invention are as follows:

[0034] 1. The invention has a reasonable structure. This tooling can automatically complete the feeding, flipping and unloading of bottle caps, avoiding manual operation, effectively avoiding human placement errors, and greatly improving detection efficiency. At the same time, the two sets of feeding and unloading units alternate feeding, which can reduce the feeding interval time of a single bottle cap and improve work efficiency.

[0035] 2. In this invention, an alignment unit is also provided. By moving the mounting plate and adjusting the angle of the belt conveyor, the alignment end of the alignment rack is precisely aligned with the axis of the detection area. At the same time, the alignment rack and the tooth plate move in opposite directions, which makes the power arm required for the belt conveyor to rotate around the axis longer. That is, a smaller force is needed to realize and drive the belt conveyor to rotate around the axis, which plays a very good role in saving effort.

[0036] 3. In this invention, a stabilizing mechanism is also provided, which generates a small rotational resistance when adjusting the angle of the belt conveyor, and generates a large magnetic attraction force after adjustment, which is conducive to the stable operation of the belt conveyor and prevents angle deflection.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example: Reference Figure 1 The dual-station alternating bottle cap center deviation detection device shown includes a belt conveyor 1, a bottle cap bearing assembly installed on the belt conveyor 1, and a loading and unloading unit;

[0050] The bottle cap carrying group and the loading and unloading unit are both provided with two sets. The bottle cap carrying group includes multiple sets of carrying blocks 9 arranged at equal intervals on the belt conveyor 1, and the carrying blocks 9 are provided with placement grooves that are compatible with the bottle caps.

[0051] The two sets of loading and unloading units are arranged obliquely symmetrically, and the two sets of loading and unloading units alternate loading operations.

[0052] As a preferred embodiment of this example, Figure 1 , Figure 5As shown, the loading and unloading unit includes a mounting frame 2 with a first electric telescopic rod 3, a second electric telescopic rod 5 with a first electric rotating seat 6 mounted on its output end, and an electric gripper mounted on the lower end of the first electric rotating seat 6.

[0053] Mounting frame 2 is obliquely mounted on belt conveyor 1. A long slide bar 4 is slidably provided at the lower end of mounting frame 2, and the right end of the long slide bar 4 is connected to the output end of the first electric telescopic rod 3.

[0054] The electric gripper is equipped with two sets of grippers. One of the grippers is equipped with a second electric rotating seat 7. The second electric rotating seat 7 and the other set of grippers are each equipped with a gripping block 8 on their opposite ends.

[0055] The motion paths of the two sets of electric grippers are L1 and L2, and the motion paths L1 and L2 intersect.

[0056] During installation, place this device on the inspection platform of the image measuring instrument, ensuring that the intersection of motion paths L1 and L2 coincides with the axis of the inspection area:

[0057] After installation, place the bottle caps into the placement grooves of the carrier 9 on the conveyor belt in sequence. After the bottle caps are placed, the PLC controller controls the second electric telescopic rod 5 to move downward, so that the clamping block 8 moves downward a certain distance and stops. At this time, the clamping block 8 is still above the carrier 9 and on both sides of the bottle cap, with the upper end of the bottle cap above the upper end of the clamping block 8.

[0058] Then, control the two sets of gripper seats to move together to clamp and fix the bottle cap. Then, control the second electric telescopic rod 5 to drive the bottle cap to move upward. When the gripper block 8 returns to its original position, the first electric telescopic rod 3 works to drive the slide bar 4 to move and move the bottle cap to the detection area. Then, the second electric telescopic rod 5 drives the bottle cap to move downward, and the two sets of grippers move outward to return to their original position, placing the bottle cap in the detection area. Then, the first electric telescopic rod 3 moves the grippers out of the detection area.

[0059] After the inspection is completed, the bottle cap is rotated 180° and placed on the inspection table for reverse inspection by the cooperation of the first electric telescopic rod 3, the second electric telescopic rod 5, and the second electric rotating seat 7. After placement, the electric gripper moves out of the inspection range. After the inspection is completed, the electric gripper clamps the bottle cap (at the same time, another set of electric grippers begins to move downward to perform clamping and loading operations). The second electric telescopic rod 5 drives the bottle cap to move upward to restore its original height, and then the first electric telescopic rod 3 drives the gripper to return to its initial position. During this process (i.e., clamping...), the bottle cap is rotated 180° and placed on the inspection table for reverse inspection. After placement, the electric gripper moves out of the inspection range. After inspection, the electric gripper clamps the bottle cap (at the same time, another set of electric grippers begins to move downward to perform clamping and loading operations). The second electric telescopic rod 5 drives the bottle cap to move upward to restore its original height, and then the first electric telescopic rod 3 drives the gripper to return to its initial position. Before the grippers return to their original positions, the first electric rotary seat 6 rotates 90 degrees, causing the bottle cap being held to deviate from directly above the belt conveyor 1. The two grippers release, causing the bottle cap to fall away from the inspection station. The first electric rotary seat 6 then rotates in the opposite direction, causing the electric grippers to return to their original positions. Finally, the grippers move to directly above the bottle cap at the clamping station. At the same time, another set of electric grippers has placed the bottle cap to be inspected in the inspection area. After both sets of bottle caps in the same row have been clamped, the belt conveyor works intermittently, moving the next bottle cap to the clamping station.

[0060] This fixture can automatically complete the loading, flipping and unloading of bottle caps, avoiding manual operation, effectively preventing human placement errors, and greatly improving detection efficiency. At the same time, the two sets of loading and unloading units alternate loading, which can reduce the loading interval time of a single bottle cap and improve work efficiency.

[0061] The following points should be noted: 1. Belt conveyor 1, first electric telescopic rod 3, second electric telescopic rod 5, first electric rotating seat 6, and second electric rotating seat 7 are all electrically connected to the PLC controller; 2. The two sets of electric grippers do not contact or collide during alternating operation; 3. Mounting plate 12 can be fixedly connected to the detection table with screws; 4. The motion paths L1 and L2 pass through the axis of the bottle cap located in the clamping area, which facilitates the subsequent alignment of the bottle cap axis with the axis of the detection area, achieving precise placement, effectively reducing subsequent detection errors, and improving detection accuracy; 5. Both sets of electric grippers unload material to the outside of belt conveyor 1 during unloading, i.e., unloading the bottle cap after detection.

[0062] As a preferred embodiment of this example, Figure 1 As shown, the lower end of the belt conveyor 1 is equipped with a mounting plate 12 and a ball bearing 13 on the left and right sides respectively. The lower end of the ball bearing 13 is on the same horizontal plane as the lower end of the mounting plate 12. The upper end of the mounting plate 12 is rotatably provided with a rotating column 10 through a bearing 11, and the upper end of the rotating column 10 is fixedly connected to the belt conveyor 1.

[0063] During installation, the angle can be adjusted by rotating the belt conveyor 1 relative to the mounting plate 12 so that the intersection of the motion paths L1 and L2 coincides with the axis of the inspection area, facilitating adjustment and alignment.

[0064] As a preferred embodiment of this invention, an installation alignment unit is also provided to achieve precise installation of the device and prevent the bottle cap from being unable to be placed at the center of the detection area due to excessive installation errors.

[0065] As a preferred embodiment of this example, Figure 1 , Figure 2 and Figure 4 As shown, the mounting alignment unit includes an alignment rack 17 that is slidably connected to the belt conveyor 1, a transmission gear 18 that is rotatably disposed below the belt conveyor 1, and a toothed plate 19 that meshes with the transmission gear 18.

[0066] The toothed plate 19 is slidably disposed below the belt conveyor 1, and an L-shaped rod 20 is provided on the outer wall of the toothed plate 19;

[0067] The transmission gear 18 meshes with the alignment rack 17, and the alignment end of the alignment rack 17 is set with a tapered structure;

[0068] One end of the alignment rack 17 slides through the limiting block set at the bottom of the belt conveyor 1, and a blocking block 21 is set at the upper end of the alignment rack 17. The alignment rack 17 is located in the middle of the two sets of electric grippers.

[0069] The straight-line distance between the alignment end of the alignment rack 17 and the intersection point is D1;

[0070] The straight-line distance between the end of the blocking block 21 near the limiting block and the alignment end of the alignment toothed rod 17 is D1.

[0071] During installation, place the device on the inspection table of the image measuring instrument. The upper ends of the mounting plate 12 and the ball bearing 13 are in contact with the upper surface of the inspection table. The installer holds the two ends of the mounting plate 12 with one hand and the fingers of the other hand hold the L-shaped rod 20. The fingers push backward to drive the toothed plate 19 to move closer to the ball bearing 13. The movement of the toothed plate 19 will drive the transmission gear 18 to rotate. The transmission gear 18 will drive the alignment toothed rod 17 to move forward. Finally, the side end of the blocking block 21 will contact the limiting block to form a block. At this time, the extension length of the alignment toothed rod 12 is D1. The movable mounting plate 12 will drive the belt conveyor 1 to move. In conjunction with the rotation of the belt conveyor 1 around the axis of the rotating column 10, the tip of the alignment toothed rod 17 will coincide with the axis of the inspection area. After alignment, push the toothed plate 19 forward to return the toothed plate 19 and the alignment toothed rod 17 to their original positions.

[0072] Then, using a small drilling tool, drill mounting holes on the testing table through the through holes (which are made on the mounting plate 12). Use screws to fix the mounting plate 12 to the testing table. Alternatively, use adhesive (usually adhesive) to apply adhesive along the contact point between the outer edge of the mounting plate 12 and the testing table to fix and limit the mounting plate 12.

[0073] It should be noted that during alignment adjustment, the alignment rack 17 and the toothed plate 19 move in opposite directions. When the toothed plate 19 moves backward, the power arm required for the belt conveyor 1 to rotate around the axis of the rotating column 10 becomes longer. This means that a smaller force is needed to achieve and drive the belt conveyor 1 to rotate around the axis of the rotating column 10, which has a good effect of saving effort.

[0074] As a preferred embodiment of this invention, a stabilizing mechanism is also provided to ensure that the belt conveyor 1 operates stably and does not move.

[0075] In actual use, each power supply device will generate a certain amount of vibration when it is working. This vibration may cause the belt conveyor 1 to rotate relative to the mounting plate 12, which will cause the intersection point to fail to coincide with the axis of the detection area, thus affecting the detection accuracy.

[0076] As a preferred embodiment of this example, Figure 3 , Figure 6 and Figure 7 As shown, the stabilizing mechanism includes a slider 24 that is slidably disposed at the bottom of the belt conveyor 1, a block 25 on which two sets of first magnets 27 are symmetrically mounted at the upper end, and a square block 26 that is vertically slidably disposed in the inner cavity of the rotating column 10.

[0077] The square block 26 is adapted to slide in the cylindrical cavity of the rotating column 10. Two sets of second magnets 28 are symmetrically arranged in the mounting groove at the lower end of the square block 26. The two sets of second magnets 28 correspond one-to-one with the two sets of first magnets 27, and the magnetic poles at opposite ends are opposite.

[0078] The lower end of the square block 26 is provided with a movable cavity 33, and the movable cavity 33 is located below the second magnet 28. The inner cavity of the movable cavity 33 is provided with a magnetic shielding plate 29, and the upper end of the magnetic shielding plate 29 is fixed with a column 30, and the column 30 is rotatably connected to the square block 26. The column 30 is provided with a spiral groove 31.

[0079] One end of the slider 24 is connected to one end of the pull rope 23, and the other end of the pull rope 23 passes through and extends into the inner cavity of the rotating column 10 and is connected to the movable rod 32. The lower end of the movable rod 32 extends into the inner cavity of the square block 26, and the lower end is located in the spiral groove 31.

[0080] The toothed plate 19 is provided with an abutment rod 22 adapted to the slider 24 at its end;

[0081] The block 25 is fixedly mounted on the mounting plate 12 and located in the inner cavity of the rotating column 10.

[0082] Initially, the magnetic attraction of the first magnet 27 and the second magnet 28 causes the square block 26 to be in close contact with the upper end of the cylindrical block 25. At this time, the rotating column 10 needs to overcome the magnetic force and the friction between the square block 26 and the block 25 to rotate. Therefore, the magnetic force and friction form resistance to maintain the stability of the belt conveyor 1 during operation.

[0083] When the toothed plate 19 moves backward, the abutment rod 22 at its end will contact the slider 24 and push the slider 24 to move backward. The backward movement of the slider 24 will drive the movable rod 32 to move upward through the pull rope 23. Since the lower end of the movable rod 32 is slidably set in the spiral groove 31, when the movable rod 32 moves upward, it will drive the column 30 and the magnetic shielding plate 29 to rotate. The magnetic shielding plate 29 stops moving when it rotates between the two sets of second magnets 28 and the two sets of first magnets 27. At this time, the movable rod 32 cannot move upward relative to the column 30, and the magnetic force is weakened by the magnetic shielding effect of the magnetic shielding plate 29. As the slider 24 continues to move backward, the pull rope 23 will drive the square block 26 to move upward through the movable 32, so that the distance between the magnets increases, the magnetic force is reduced, and it is easier for the subsequent operator to use a smaller force to make the belt conveyor 1 rotate relative to the mounting plate 12.

[0084] During the process of the toothed plate 12 moving forward and returning to its original position, the slider 24 moves forward through the pull rope 23 by the gravity of the movable rod 32 and the square block 26. When the lower end of the square block 26 contacts the upper end of the circular block 25, the slider 24 moves by the gravity of the movable rod 32. The movable rod 32 moves downward relative to the column 30 by its own gravity and drives the magnetic shielding plate 29 to rotate. Finally, the magnetic shielding plate 29 returns to its original position, releasing the magnetic shielding effect, so that the fixed limit between the square block 26 and the block 25 is completed by the magnetic attraction.

[0085] The stabilizing mechanism generates low rotational resistance when adjusting the angle of the belt conveyor 1 (facilitating low-resistance rotation by personnel). After adjustment, it generates a large magnetic attraction force, which helps the belt conveyor 1 to work stably and prevents angle deflection.

[0086] It should be noted that the contact surface between square block 26 and block 25 is set to a rough surface, which can increase the rotational friction.

[0087] As a preferred embodiment of this example, Figure 8 and Figure 9As shown, the first electric rotary seat 6 and the second electric rotary seat 7 have the same structure, both including a rotary motor 14 and a gear ring 16 installed in the housing;

[0088] A gear 15 that meshes with a gear ring 16 is mounted on the output shaft of the rotary motor 14;

[0089] The upper end of the electric gripper is rotatably mounted in the inner cavity of the first electric rotary seat 6.

[0090] One set of clamping blocks 8 is rotatably connected to the second electric rotary seat 7;

[0091] The two sets of toothed rings 16 are respectively installed in the mounting slots provided on the electric gripper and the clamping block 8.

[0092] The rotating motor 14 operates and, in conjunction with the meshing connection between the gear 15 and the gear ring 16, causes the clamping block 8 or the electric gripper to rotate.

[0093] As a preferred embodiment of this example, Figure 1 As shown, the clamping end of the clamping block 8 is provided with an arc-shaped concave surface to fit the outer circle contour of the bottle cap.

[0094] During clamping, the concave arc surface makes contact with the outer cylindrical surface of the bottle cap, which can automatically center the bottle cap and ensure that the center of the bottle cap always coincides with the midpoint of the axis connection line of the two sets of clamping blocks 8 after clamping, thus realizing the self-centering clamping of the bottle cap.

[0095] The self-centering clamping design with an arc-shaped concave surface ensures that the center position of the bottle cap is completely consistent each time it is clamped, completely eliminating the positioning deviation caused during the clamping process and further improving the positioning accuracy of bottle cap transfer, flipping, and detection.

[0096] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
