Description

Technical Field

[0001] The present invention relates to the technical field of implant height detection, and in particular to a detection device and method for efficiently detecting implant height. Background Art

[0002] The implant 1 installed in the maxillary or mandibular bone of a human body is made of alloy material, which is processed by different lathes. The structure of a certain type of implant 1 is as follows Figure 1~Figure 2 As shown, the implant 1 includes a body 2 and a base 3, wherein the base 3 is fixedly arranged on the top of the body 2, a step surface is formed between the base 3 and the body 2, and a threaded hole arranged along the axial direction of the implant 1 is opened on the top surface of the base 3, wherein the function of the threaded hole is to connect with the threaded head on the denture (denture is also called false tooth) so as to fix the denture on the implant 1.

[0003] After a batch of implants are produced in the workshop, workers have to test the height h of each implant 1 (the purpose of the test is to detect the height h of some implants 1 that exceed the design range due to workers' insufficient processing experience). After the test, workers will remove unqualified products whose height exceeds the design range, and put qualified products whose height does not exceed the design range into the finished product basket.

[0004] In the workshop, the method for workers to detect the height of the implant 1 is:

[0005] S1. A worker takes out an implant 1 to be tested from a basket, and supports the base 3 of the implant 1 on a platform. At the same time, the body 2 of the implant 1 is supported on a pad 5 located on a platform 4. At this time, the axis of the implant 1 is in a horizontal straight line, so that the implant 1 is installed in place. Figure 3 As shown;

[0006] S2, the worker holds a vernier caliper, places the two jaws of the vernier caliper against the left and right ends of the implant 1, and then reads the reading on the vernier caliper, which is the height h of the implant 1;

[0007] S3. The worker determines whether the height h exceeds the design range. If the height h exceeds the design range, the implant 1 is determined to be a defective product, and the worker removes the defective product; if the height h does not exceed the design range, the implant 1 is determined to be a qualified product, and the worker puts the qualified product into the finished product basket;

[0008] S4. The worker repeats the operations of steps S1 to S3 to detect the heights of the multiple implants 1 in the basket.

[0009] However, although the method in the workshop can detect the height of a batch of implants 1, in actual operation, workers still reflect the following technical defects:

[0010] I. In steps S2 to S3, it is necessary to manually operate the vernier caliper so that the two claws thereon are respectively close to the left and right ends of the implant 1, and it is also necessary to manually read the reading on the vernier caliper to complete the measurement of the height of an implant 1; and the entire operation is completed manually, and the number of implants 1 to be tested in the material basket is as many as 40 to 50. The workers manually use the vernier caliper for testing, which undoubtedly takes a long time to complete the height detection of all the implants 1 in the material basket, thereby reducing the detection efficiency of the height of the implant 1.

[0011] II. Sometimes, waste chips 6 are attached to the top surface of the base 3 of the implant 1 (because during the machining process, some of the waste chips fall into the basket containing the implant 1, so the waste chips 6 will adhere to the top surface of the implant 1). Figure 4 As shown, due to the presence of waste chips 6, the height H actually measured by the vernier caliper is the sum of the thickness of the waste chips 6 and the height of the implant 1, and the height H is obviously greater than the height h of the implant 1, which causes workers to mistakenly judge qualified products as unqualified products, resulting in a technical defect of low detection accuracy.

[0012] Therefore, there is an urgent need for a detection device and method that can greatly improve the efficiency and accuracy of implant height detection. Summary of the invention

[0023] The detection device also includes a controller, which is electrically connected to the micro switch, the lifting cylinder, the lifting cylinder, the first motor and the second motor via a signal line.

[0024] A method for efficiently detecting implant height comprises the following steps:

[0025] S1. Positioning and installation of the first implant: The worker takes out an implant to be tested from the material basket, and inserts the body of the implant into the positioning hole of the loading mechanism from top to bottom. Since the diameter of the positioning hole is equal to the diameter of the top end of the body of the implant, the positioning and installation of the implant is achieved. At this time, the base of the implant is just supported on the top surface of the positioning plate, and the body of the implant is exposed below the positioning plate;

[0026] S2, control the first motor of the feeding mechanism to start, the first motor drives the rotating plate to rotate, the rotating plate drives the guide seat to rotate synchronously, the guide seat drives the square rod, the bracket, the support plate, and the positioning plate to rotate synchronously, the positioning plate drives the implant installed therein to rotate synchronously, when the implant rotates 180°, the controller controls the first motor to turn off, at this time, the base of the implant is just below the steel brush, and at the same time, the support plate is just above the lifting head of the lifting mechanism;

[0027] S3. Clean away the debris attached to the top surface of the implant. The specific steps are as follows:

[0028] S31, the piston rod of the lifting cylinder of the control lifting mechanism extends upward, the piston rod drives the lifting head to move upward, after the lifting head passes through the through hole, the support plate is lifted upward, the support plate drives the square rod to move upward along the axial direction of the guide seat, the square rod drives the positioning plate to move upward, and the positioning plate drives the implant to move upward synchronously; when the piston rod of the lifting cylinder is fully extended, the top surface of the base of the implant just contacts with the steel brush;

[0029] S32, controlling the drive motor to start, the drive motor drives the disc to rotate, and the disc drives the steel brush to rotate on the horizontal plane. During the rotation process, the steel brush cleans away the waste debris attached to the top surface of the implant; after cleaning for a period of time, the controller controls the drive motor to turn off;

[0030] S4, the piston rod of the lifting cylinder of the control lifting mechanism is retracted downward, the piston rod drives the lifting head to move downward, under the dead weight of the square rod and the support plate, the support plate moves downward synchronously with the lifting head, the support plate drives the square rod to move downward synchronously, the square rod drives the positioning plate to move downward synchronously, the positioning plate drives the implant to move downward synchronously, when the lifting head is reset, the support plate is re-supported on the bottom end of the bracket and covers the through hole, and at the same time, the implant is reset;

[0031] S5. The first implant height test, the specific steps are as follows:

[0032] S51, the second motor of the control detection mechanism is started, the second motor drives the turntable to rotate synchronously, the turntable drives the first frame and the second frame to rotate synchronously, the second frame drives the lifting cylinder, V-shaped plate, rod, pressure column head and floating rod thereon to rotate synchronously, when the second frame rotates 180°, the controller controls the second motor to turn off, at this time, the pressure column head is just above the implant, and at the same time, the micro switch is at the lower left of the implant;

[0033] S52, the piston rod of the lifting cylinder of the control detection mechanism extends downward, the piston rod drives the lifting plate to move downward, the lifting plate drives the rod, the roller, the floating rod, the pressure column head, the floating plate and the vertical spring to move downward synchronously, when the bottom surface of the pressure column head contacts the top surface of the implant, the roller just approaches the first side plate of the V-shaped plate;

[0034] As the piston rod of the lifting cylinder continues to extend downward, the lifting plate continues to move downward relative to the stationary floating rod, and the pressure column head presses and fixes the implant between the pressure column head and the positioning plate to achieve fixation of the implant. At the same time, the roller presses on the first side plate of the V-shaped plate, and the first side plate compresses the tension spring. The first side plate also drives the second side plate to rotate clockwise relative to the pin shaft, and the second side plate drives the connecting plate to rotate clockwise synchronously, and the connecting plate drives the micro switch to rotate clockwise synchronously, and the spring piece of the micro switch moves toward the bottom end of the implant.

[0035] When the piston rod of the lifting cylinder is fully extended, the spring of the micro switch rotates to the highest position. At this time, if the controller receives an electrical signal from the micro switch, it means that the spring touches the bottom end of the implant, which means that the height of the implant is not within the design range. The worker determines that the implant is a defective product. Then the worker controls the piston rod of the lifting cylinder to retract upward, and the piston rod drives the lifting plate to move upward. The lifting plate drives the rod, roller, floating rod, pressure column head, floating plate and vertical spring to move upward. During the upward movement, the pressure column head is separated from the defective product. At the same time, under the restoring force of the tension spring, the V-shaped plate is reset. The worker takes the defective product out of the positioning hole of the positioning plate and throws it into the waste basket.

[0036] If the controller does not receive an electrical signal from the micro switch when the spring of the micro switch rotates to the highest position, it means that the spring does not touch the bottom end of the implant, which means that the height of the implant is within the design range, and the worker determines that the implant is a qualified product; then the worker controls the piston rod of the lifting cylinder to retract upward, and when the V-shaped plate is reset, the worker takes the qualified product out of the positioning hole of the positioning plate and puts it into the finished product basket, thus finally completing the detection of the height of the first implant;

[0037] S6. The worker repeats the operations of steps S1 to S5 to detect the heights of multiple implants in the basket.

[0038] The present invention has the following advantages: greatly improving the efficiency of implant height detection and greatly improving the accuracy of implant height detection. BRIEF DESCRIPTION OF THE DRAWINGS

A square hole arranged along the axial direction is opened in the guide seat 13, and a square rod 16 matching with it is slidably installed in the square hole. A support plate 17 covering the through hole 15 is fixed at the bottom end of the square rod 16. The top end of the square rod 16 extends above the guide seat 13, and a positioning plate 18 is fixed on the extended end. A positioning hole 19 is opened in the positioning plate 18, and the diameter of the positioning hole 19 is equal to the diameter of the top end of the body 2 of the implant 1.

A floating rod 37 is slidably passed through the right end of the lifting plate 35, a pressure column head 38 is fixedly provided at the bottom end of the floating rod 37, a floating plate 39 is fixedly provided at the top end of the floating rod 37, a vertical spring 40 is sleeved on the floating rod 37, and the upper and lower ends of the vertical spring 40 are respectively fixedly provided on the floating plate 39 and the lifting plate 35.

[0075] The lifting mechanism 9 includes a lifting cylinder 41 fixedly mounted on the workbench 7 , and a lifting head 42 is fixedly mounted on the working end of the piston rod of the lifting cylinder 41 .

[0076] The detection device also includes a controller, which is electrically connected to the micro switch 33, the lifting cylinder 41, the lifting cylinder 34, the first motor 11 and the second motor 20 via a signal line. The worker can control the extension or retraction of the piston rods of the lifting cylinder 41 and the lifting cylinder 34 through the controller, and can also control the start or shutdown of the first motor 11 and the second motor 20; when the spring piece 44 of the micro switch 33 is subjected to downward pressure, the micro switch 33 will send an electrical signal to the controller.

[0077] A method for efficiently detecting implant height comprises the following steps:

[0078] S1. Positioning and installation of the first implant 1: The worker takes out an implant 1 from the basket. Figure 1~Figure 2 As shown in the figure, the implant 1 to be tested is inserted from top to bottom into the positioning hole 19 of the feeding mechanism 8. Since the diameter of the positioning hole 19 is equal to the diameter of the top end of the body 2 of the implant 1, the positioning installation of the implant 1 is achieved. Fig.17 As shown, at this time, the base 3 of the implant 1 is just supported on the top surface of the positioning plate 18, and the body 2 of the implant 1 is exposed below the positioning plate 18;

[0079] S2, control the first motor 11 of the feeding mechanism 8 to start, the first motor 11 drives the rotating plate 12 to rotate, the rotating plate 12 drives the guide seat 13 to rotate synchronously, the guide seat 13 drives the square rod 16, the bracket 14, the support plate 17, and the positioning plate 18 to rotate synchronously, the positioning plate 18 drives the implant 1 positioned and installed therein to rotate synchronously, when the implant 1 rotates 180°, the controller controls the first motor 11 to turn off, at this time, the base 3 of the implant 1 is just under the steel brush 26, as shown in FIG. Fig.18 As shown, at the same time, the support plate 17 is just above the lifting head 42 of the lifting mechanism 9;

[0080] S3, cleaning away the waste 6 attached to the top surface of the implant 1, the specific operation steps are:

[0081] S31, the piston rod of the lifting cylinder 41 of the control lifting mechanism 9 extends upward, the piston rod drives the lifting head 42 to move upward, after the lifting head 42 passes through the through hole 15, the support plate 17 is lifted upward, the support plate 17 drives the square rod 16 to move upward along the axial direction of the guide seat 13, the square rod 16 drives the positioning plate 18 to move upward, and the positioning plate 18 drives the implant 1 to move upward synchronously; when the piston rod of the lifting cylinder 41 is fully extended, the top surface of the base 3 of the implant 1 just contacts with the steel brush 26, as shown in FIG. Fig.19 As shown;

[0082] S32, control the drive motor 24 to start, the drive motor 24 drives the disc 25 to rotate, and the disc 25 drives the steel brush 26 to rotate on the horizontal plane. During the rotation process, the steel brush 26 cleans the waste 6 attached to the top surface of the implant 1; after cleaning for a period of time, the controller controls the drive motor 24 to turn off;

[0083] Among them, it can be seen from steps S1 to S3 that the detection device first controls the piston rod of the lifting cylinder 41 of the lifting mechanism 9 to extend upward, so that the top surface of the base 3 of the implant 1 positioned and installed in the feeding mechanism 8 contacts the steel brush 26, and then controls the drive motor 24 to start, which can drive the steel brush 26 to rotate on the top surface of the implant 1. During the rotation process, the waste 6 attached to the top surface of the implant 1 is cleaned off, thereby ensuring that in the process of detecting the height in step S5, the detected height is the actual height h of the implant 1, rather than the height H. It can be seen that before detecting the height, the detection device pre-cleans the waste 6 attached to the top surface of the implant 1, thereby greatly improving the detection accuracy of the implant height.

[0084] S4, the piston rod of the lifting cylinder 41 of the control lifting mechanism 9 is retracted downward, and the piston rod drives the lifting head 42 to move downward. Under the dead weight of the square rod 16 and the support plate 17, the support plate 17 moves downward synchronously with the lifting head 42, and the support plate 17 drives the square rod 16 to move downward synchronously, and the square rod 16 drives the positioning plate 18 to move downward synchronously, and the positioning plate 18 drives the implant 1 to move downward synchronously. When the lifting head 42 is reset, the support plate 17 is re-supported on the bottom end of the bracket 14 and covers the through hole 15. At the same time, the implant 1 is reset, as shown in FIG. Fig. 20 As shown;

[0085] S5. Detection of the height of the first implant 1, the specific operation steps are as follows:

[0086] S51, control the second motor 20 of the detection mechanism 10 to start, the second motor 20 drives the turntable 21 to rotate synchronously, the turntable 21 drives the first frame 22 and the second frame 23 to rotate synchronously, the second frame 23 drives the lifting cylinder 34, the V-shaped plate 28, the rod 36, the pressure column head 38 and the floating rod 37 thereon to rotate synchronously, when the second frame 23 rotates 180°, the controller controls the second motor 20 to turn off, at this time, the pressure column head 38 is just above the implant 1, as shown in FIG. Fig. 20 As shown, at the same time, the micro switch 33 is located at the lower left of the implant 1;

[0087] S52, the piston rod of the lifting cylinder 34 of the control detection mechanism 10 extends downward, the piston rod drives the lifting plate 35 to move downward, the lifting plate 35 drives the rod 36, the roller 43, the floating rod 37, the pressure column head 38, the floating plate 39 and the vertical spring 40 to move downward synchronously, when the bottom surface of the pressure column head 38 contacts the top surface of the implant 1, as shown in FIG. Fig.21 As shown, the roller 43 is just close to the first side plate 29 of the V-shaped plate 28;

[0088] As the piston rod of the lifting cylinder 34 continues to extend downward, the lifting plate 35 continues to move downward relative to the stationary floating rod 37, and the pressure column head 38 presses and fixes the implant 1 between the pressure column head 38 and the positioning plate 18 to fix the implant 1. At the same time, the roller 43 presses on the first side plate 29 of the V-shaped plate 28, and the first side plate 29 compresses the tension spring 30. The first side plate 29 also drives the second side plate 31 to rotate clockwise relative to the pin shaft, and the second side plate 31 drives the connecting plate 32 to rotate clockwise synchronously, and the connecting plate 32 drives the micro switch 33 to rotate clockwise synchronously, and the spring piece 44 of the micro switch 33 moves toward the bottom end of the implant 1.

[0089] When the piston rod of the lifting cylinder 34 is fully extended, the spring 44 of the micro switch 33 rotates to the highest position. At this time, if the controller receives an electrical signal from the micro switch 33, it means that the spring 44 touches the bottom end of the implant 1. Figure 22~Figure 23 As shown, it further indicates that the height of the implant 1 is not within the design range, and the worker determines that the implant 1 is a defective product; then the worker controls the piston rod of the lifting cylinder 34 to retract upward, and the piston rod drives the lifting plate 35 to move upward, and the lifting plate 35 drives the rod 36, the roller 43, the floating rod 37, the pressure column head 38, the floating plate 39 and the vertical spring 40 to move upward. During the upward movement, the pressure column head 38 is separated from the defective product. At the same time, under the restoring force of the tension spring 30, the V-shaped plate 28 is reset; the worker takes the defective product out of the positioning hole 19 of the positioning plate 18 and throws it into the waste basket. The taking direction is as shown in FIG. Fig.24 As indicated by the arrow;

[0090] If the controller does not receive an electrical signal from the micro switch 33 when the spring 44 of the micro switch 33 rotates to the highest position, it means that the spring 44 does not touch the bottom end of the implant 1. Fig.25 As shown, it further indicates that the height of the implant 1 is within the design range, and the worker determines that the implant 1 is a qualified product; then the worker controls the piston rod of the lifting cylinder 34 to retract upward, and when the V-shaped plate 28 is reset, the worker takes the qualified product out of the positioning hole 19 of the positioning plate 18 and puts it into the finished product basket, thereby finally completing the detection of the height of the first implant 1;

[0091] S6. The worker repeats the operations of steps S1 to S5 to detect the heights of the multiple implants 1 in the basket.

[0092] Among them, it can be seen from step S5 that the detection device only needs to control the piston rod of the lifting cylinder 34 of the detection mechanism 10 to extend downward, so as to first press the implant 1 through the pressure column head 38, and then determine whether the height of the implant 1 is within the design range automatically and quickly by determining whether the spring piece 44 of the micro switch 33 is pressed down by the bottom end of the implant 1, thereby facilitating workers to quickly determine whether the product is defective or qualified.

[0093] It can be seen that this detection device is better than Figure 3~Figure 4 The detection method shown does not require a worker to operate a vernier caliper so that the two claws thereon are respectively close to the left and right ends of the implant 1, nor does it require a worker to read the readings on the vernier caliper. Instead, it automatically and quickly determines whether the height of the implant 1 is within the design range, thereby achieving the completion of the height detection of all implants 1 in the material basket in a short time, thereby greatly improving the detection efficiency of the height of the implant 1.
