Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an automatic testing device for dentures. Background Technology

[0002] When all natural teeth (including roots) are missing, it is called edentulism. Complete dentures are restorations made for edentulous patients, mainly composed of a denture base and artificial teeth to restore the missing teeth and their supporting tissues. Traditional complete dentures (as opposed to implant-retained complete dentures) rely on the suction force generated by the close fit between the denture base and the mucosa, as well as atmospheric pressure, to achieve retention. They adhere to the alveolar ridges of the upper and lower jaws to achieve various functions. Therefore, the uniform contact between the denture base and the mucosa, as well as the occlusal contact relationship of the artificial teeth, are closely related to the effectiveness of the complete denture restoration. After the denture is fabricated, its surface needs to be tested for corrosion resistance.

[0003] In related technologies, dentures are tested manually using handheld testing instruments. However, manual testing is prone to blind spots, leading to larger errors and inaccurate test results. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an automatic testing device for dentures.

[0005] The automatic testing device for dentures provided in this application adopts the following technical solution:

[0006] An automatic testing device for dentures, comprising:

[0007] A work frame, which includes a loading area and an inspection area, wherein the loading area is used for loading materials and the work frame is used for placing and moving dentures;

[0008] The feeding assembly is mounted on the work frame and includes a feeding beam, a feeding motor, and a feeding slider. The feeding beam is fixedly connected to the work frame, and the feeding motor is mounted on the feeding beam. The feeding motor is used to drive the feeding slider to move along the feeding beam, and the feeding slider is used to carry the dentures.

[0009] A clamping assembly, comprising a clamping cylinder, a connecting plate, and clamping claws, wherein the clamping cylinder is mounted on a feeding slider, the connecting plate is connected to the piston rod of the clamping cylinder, and the clamping claws are hinged to the connecting plate. The clamping claws are used to clamp dentures, and the clamping cylinder is used to drive the clamping claws to move towards or away from the dentures in a vertical direction.

[0010] A rotating assembly, comprising a rotating motor and a rotating shaft, wherein the rotating motor is mounted on the feeding crossbeam and drives the rotating shaft to rotate, the rotating shaft rotating relative to the piston rod of the clamping cylinder, and the connecting plate being connected to the end of the rotating shaft away from the clamping cylinder at the shaft center, the rotation of the rotating shaft causing the clamping claw to rotate;

[0011] A deflection assembly, which is used to drive the connecting plate to deflect relative to the rotation axis at an angle;

[0012] The testing component is located at the testing point of the work stand and is used to perform surface testing on dentures.

[0013] By adopting the above technical solution, the feeding slider and the clamping cylinder work together to drive the clamping claw to clamp and fix the denture, and move it from the feeding point to the inspection point. When the inspection piece inspects the denture, the rotating shaft drives the clamping claw and the denture to rotate. At the same time, the deflection component drives the connecting plate to deflect relative to the rotating rod shaft. The connecting plate drives the clamping claw and the denture to deflect while rotating, which improves the detail and comprehensiveness of the inspection of the denture surface, reduces the blind spots in the inspection, reduces the error generated by the inspection data, and thus improves the accuracy of the inspection results.

[0014] Preferably, the feeding assembly further includes a feeding screw, the feeding crossbeam has a feeding cross groove along its own length, the feeding screw is located in the feeding cross groove and one end is fixedly connected to the output shaft of the feeding motor, and the feeding slider is threadedly connected to the feeding screw and moves along the feeding cross groove.

[0015] By adopting the above technical solution, the feeding motor starts and drives the feeding screw to rotate, which in turn drives the feeding slider to move along the feeding cross groove. The feeding slider carries the clamping cylinder, clamping claw and denture to move synchronously, which facilitates the movement of the denture from the feeding point to the testing point.

[0016] Preferably, the clamping assembly further includes an abutment ring, a collar, and a clamping spring. One end of the clamping spring is fixedly connected to the side of the connecting plate away from the clamping cylinder, and the other end of the clamping spring is fixedly connected to the abutment ring. The collar is fixedly connected to the circumferential surface of the abutment ring and is sleeved on the clamping claw. When the abutment ring moves closer to the connecting plate, the collar moves accordingly, causing the clamping claw to open.

[0017] Preferably, the clamping claw includes a connecting part, an opening and closing part, and a clamping part. The connecting part is fixedly connected to the connecting plate, the opening and closing part is hinged to the connecting part, the clamping part is fixedly connected to the end of the opening and closing part away from the connecting part, the collar is sleeved on the opening and closing part, and the clamping part is used to clamp the denture.

[0018] By adopting the above technical solution, the piston rod of the clamping cylinder extends, driving the abutment ring to move downward and abut against the denture. The abutment ring causes the clamping spring to change from its natural state to a compressed state. The collar moves with the abutment ring. Since the collar is fitted on the opening and closing part, the movement of the collar drives the opening and closing part to rotate relative to the connecting part and open. The piston rod of the clamping cylinder retracts, so that the clamping part clamps the denture. At the same time, under the elastic force of the clamping spring, the abutment ring moves away from the connecting plate. The abutment ring and the clamping part cooperate with each other to clamp and fix the denture.

[0019] Preferably, a transmission gear is provided at one end of the rotating shaft near the clamping cylinder, and a drive gear is provided at the end of the output shaft of the rotating motor, wherein the transmission gear meshes with the drive gear.

[0020] Preferably, a support plate is provided on the feeding beam near the detection point, the rotating motor is slidably mounted on the support plate, the sliding direction of the rotating motor is consistent with the axis of the output shaft of the rotating motor, and a support plate is fixedly connected to the rotating motor, the support plate abutting against the side of the transmission gear away from the drive gear.

[0021] By adopting the above technical solution, when the denture reaches the inspection point, the drive motor moves close to the loading beam, causing the drive gear and transmission gear to mesh. Simultaneously, the support plate abuts against the transmission gear, limiting the rotation shaft axially. The rotation motor starts, the drive gear drives the transmission gear to rotate, and the transmission gear drives the rotation shaft to rotate relative to the piston rod of the clamping cylinder. This enables the clamping claw and denture to rotate, facilitating the inspection of the denture at various positions, improving the precision of the inspection, and reducing the error of the inspection data.

[0022] Preferably, the piston rod of the clamping cylinder is provided with a movable connecting rod and a movable clamping plate at its end. The movable connecting rod is fixedly connected to the movable clamping plate. The end of the rotating shaft is provided with a connecting cavity and a connecting hole along the axial direction. The connecting hole communicates with the connecting cavity. The connecting cavity is used to place the movable clamping plate.

[0023] By adopting the above technical solution, when the piston rod of the clamping cylinder extends, the movable clamping plate moves in the connecting cavity until the piston rod abuts against the end face of the rotating shaft, thus enabling the clamping cylinder to drive the rotating shaft to move along the work frame; if the supporting clamping plate supports the rotating shaft, the clamping cylinder cannot drive the rotating shaft to move downward.

[0024] Preferably, the deflection assembly includes a deflection connecting plate and a sliding rod. The deflection connecting plate is fixedly connected to the end of the piston rod of the clamping cylinder. The movable connecting rod is fixedly connected to the deflection connecting plate. The sliding rod includes a first sliding rod and a second sliding rod. One end of the first sliding rod is fixedly connected to the deflection connecting plate. The second sliding rod is slidably connected to the first sliding rod. The end of the second sliding rod away from the first sliding rod abuts against the side of the connecting plate opposite to the abutment ring.

[0025] By adopting the above technical solution, when the piston rod of the clamping cylinder extends and drives the rotating shaft to move downward, the second slide rod moves accordingly and slides into the first slide rod. At this time, the second slide rod will not generate a resisting force on the connecting plate.

[0026] Preferably, the connecting plate and the rotating shaft are connected by a ball joint, a limiting rod is fixedly connected to the rotating motor, and a limiting hole is provided on the first slide rod for the limiting rod to be inserted. After the limiting rod is inserted into the limiting hole, it abuts against the end of the second slide rod located inside the first slide rod, thereby limiting the sliding of the second slide rod.

[0027] By adopting the above technical solution, when the limiting rod is inserted into the limiting hole, the second slide rod is fixed relative to the first slide rod. When the piston rod of the clamping cylinder extends out and does not abut against the end face of the rotating shaft, the second slide rod generates abutting force on the connecting plate. Since the connecting plate and the rotating shaft are not ball-jointed, the axis of the connecting plate relative to the rotating shaft can be deflected, further improving the comprehensiveness of the detection of the denture surface by the detection component and further improving the accuracy of the detection data.

[0028] Preferably, it also includes a receiving assembly, which includes a receiving slide rail, a first recycling bin, and a second recycling bin. The receiving slide rail is fixedly connected to the detection point of the work frame and located below the detection piece. The first recycling bin and the second recycling bin are slidably connected to the receiving slide rail, and the first recycling bin and the second recycling bin are respectively arranged on opposite sides of the work frame. Each of the first recycling bin and the second recycling bin has a built-in drive source.

[0029] By adopting the above technical solution, after the test piece is completed, if the denture passes the test, the first recycling box slides down to the work rack to collect the qualified dentures for further processing; if the denture fails the test, the second recycling box slides down to the work rack to collect the dentures for sorting and processing.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By using a rotating motor, drive gear, and rotating shaft to perform surface corrosion resistance testing on dentures, the rotating motor drives the drive gear to rotate, the drive gear drives the rotating shaft to rotate, and the rotating shaft drives the clamping jaws and dentures to rotate synchronously. This improves the detail of the denture surface inspection, reduces blind spots, and helps improve the accuracy of the test data.

[0032] 2. Through the setting of the limiting rod, connecting plate and ball joint, when the limiting rod is inserted into the limiting hole, the second slide rod is fixed relative to the first slide rod. When the piston rod of the clamping cylinder extends and does not abut against the end face of the rotating shaft, the second slide rod generates abutting force against the connecting plate. Since the connecting plate and the rotating shaft are ball jointed, the axis of the connecting plate can be deflected relative to the rotating shaft, which further improves the comprehensiveness of the detection of the denture surface by the test piece and further improves the accuracy of the test data.

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] This application discloses an automatic testing device for dentures, such as... Figure 1 As shown, the device includes a work frame 1, a testing component 7, a feeding assembly 2, a clamping assembly 3, a rotating assembly 4, and a deflection assembly 5. The work frame 1 includes a feeding area 13 and a testing area 14. After the clamping assembly 3 clamps the denture, the feeding assembly 2 clamps the denture from the feeding area 13 and moves it to the testing area 14. The testing component 7 is set at the testing area 14 and tests the denture. In order to conduct a more comprehensive and detailed test on the denture, the rotating assembly 4 and the deflection assembly 5 control the denture to continuously rotate and deflect during the test.

[0041] like Figure 1 and 2 As shown, a feeding groove 11 is provided on the work frame 1 at the feeding point 13. A feeding block 12 is slidably connected inside the feeding groove 11. The feeding block 12 is used to place the denture. After the denture is processed in the previous step, it is directly carried by the feeding block 12 and moved along the feeding groove 11. The feeding assembly 2 includes a feeding beam 22, a feeding motor 21, a feeding screw 23, and a feeding slider 24. The feeding beam 22 is fixedly connected to the work frame 1, and the length direction of the feeding beam 22 is consistent with the length direction of the work frame 1. The feeding motor 21 is fixedly connected to one end of the feeding beam 22. A feeding groove is provided on the feeding beam 22 along its own length direction. The feeding screw 23 is located in the feeding groove, and one end is fixedly connected to the output shaft of the feeding motor 21. The feeding slider 24 is threadedly connected to the feeding screw 23 and moves along the feeding groove. The feeding motor 21 starts and drives the feeding screw 23 to rotate, and the rotation of the feeding screw 23 drives the feeding slider 24 to move.

[0042] like Figure 1 and 3 As shown, the clamping assembly 3 includes a clamping cylinder 31, clamping claws 32, a connecting plate 33, and an abutment ring 34. The cylinder body of the clamping cylinder 31 is fixedly connected to the feeding slider 24. The connecting plate 33 is connected to the piston rod of the clamping cylinder 31. There are three clamping claws 32, which are evenly arranged around the circumference of the connecting plate 33. Each clamping claw 32 includes a connecting part 321, a closing part 322, and a clamping part 323. The connecting part 321 is fixedly connected to the connecting plate 33. The closing part 322 is hinged to the connecting part 321. The clamping part 323 is fixedly connected to the end of the closing part 322 away from the connecting part 321. A clamping spring 35 is fixedly connected to the side of the connecting plate 33 away from the clamping cylinder 31. The other end of the clamping spring 35 is fixedly connected to the abutment ring 34, which is located within the space formed by the three clamping claws 32. The abutment ring 34 is fixedly connected to the collar 341 along the circumference, and the opening and closing part 322 is located inside the collar 341.

[0043] When the loading slider 24 is located at the loading point 13, the clamping cylinder 31 is activated, driving the connecting plate 33 and the abutment ring 34 to move downwards. When the abutment ring 34 abuts against the denture, it presses against the clamping spring 35, which is in a compressed state. At the same time, the abutment ring 34 drives the collar 341 to move closer to the connecting plate 33, and the opening and closing parts 322 rotate away from each other. When the piston rod of the clamping cylinder 31 retracts, the connecting plate 33 moves upwards, and the clamping spring 35 returns to its natural state under its own elastic force. At the same time, the abutment ring 34 moves away from the connecting plate 33, and the collar 341 moves with the abutment ring 34, driving the opening and closing parts 322 to rotate closer to each other, so that the clamping parts 323 cooperate with each other. The three clamping parts 323 cooperate with the abutment ring 34 to clamp and limit the denture, which helps to improve the positional stability of the denture during subsequent testing. After clamping the denture, the loading slider 24 moves along the loading transverse groove, carrying the denture to the inspection point 14.

[0044] like Figure 4 and 5 As shown, the rotating assembly 4 includes a rotating motor 41, a drive gear 411, and a rotating shaft 42. A support plate 221 is fixedly connected to the feeding beam 22. The rotating motor 41 is slidably connected to the support plate 221. The drive gear 411 is coaxially fixedly connected to the output shaft of the rotating motor 41. The axial direction of the output shaft of the rotating motor 41 is horizontal and perpendicular to the moving direction of the feeding slider 24. A connecting cavity 422 and a connecting hole 423 are provided axially on the rotating shaft 42. The connecting hole 423 communicates with the connecting cavity 422. A movable connecting rod 311 and a movable clamping plate 312 are fixedly connected to the end of the piston rod of the clamping cylinder 31. The movable connecting rod 311 is fixedly connected to the piston rod 311. The end of the movable connecting rod 311 away from the clamping cylinder 31 extends into the connecting hole 423, so that the movable clamping plate 312 is located in the connecting cavity 422. This realizes the connection between the rotating shaft 42 and the clamping cylinder 31. The end of the rotating shaft 42 away from the clamping cylinder 31 is connected to the connecting plate 33. A transmission gear 421 and a support plate 413 are fixedly connected to the rotating shaft 42. The transmission gear 421 meshes with the drive gear 411, and the support plate 413 abuts against the side of the transmission gear 421 away from the drive gear 411.

[0045] After the loading slider 24 carries the denture to the inspection area 14, the rotating motor 41 moves, causing the drive gear 411 to mesh with the transmission gear 421. The rotating motor 41 starts, causing the drive gear 411 to rotate, which in turn drives the transmission gear 421 to rotate. The transmission gear 421 then drives the rotating shaft 42 to rotate. Driven by the rotating shaft 42, the clamping jaw 32 carries the denture and rotates synchronously. When the inspection piece 7 inspects the denture, this reduces blind spots on the denture surface and improves the detail of the inspection.

[0046] like Figure 5As shown, the deflection assembly 5 includes a deflection connecting plate 51 and a sliding rod 52. The deflection connecting plate 51 is fixedly connected to the end of the piston rod of the clamping cylinder 31, and the movable connecting rod 311 is fixedly connected to the deflection connecting plate 51. The sliding rod 52 includes a first sliding rod 521 and a second sliding rod 522. One end of the first sliding rod 521 is fixedly connected to the deflection connecting plate 51, and the second sliding rod 522 is slidably connected to the first sliding rod 521. The end of the second sliding rod 522 away from the first sliding rod 521 contacts the side of the connecting plate 33 away from the abutment ring 34. The rotating shaft 42 and the connecting plate 33 are connected by a ball joint. A limiting insertion rod 412 is fixedly connected to the rotating motor 41, and a limiting insertion hole 5211 for the limiting insertion rod 412 to be inserted is provided on the first sliding rod 521.

[0047] When the loading slider 24 picks up material at the loading point 13, the piston rod of the clamping cylinder 31 extends to its first stroke. At this time, the piston rod of the clamping cylinder 31 drives the rotating shaft 42, the connecting plate 33, and the clamping claw 32 to move downward, causing the abutment ring 34 to abut against the denture. When the clamping cylinder 31 retracts, it facilitates the clamping claw 32 to clamp the denture, and at the same time, it cooperates with the abutment ring 34 to limit the denture. During this process, the second slide rod 522 slides relative to the first slide rod 521.

[0048] When the feeding slider 24 moves to the detection point 14, the drive motor carries the limiting rod 412 toward the rotating shaft 42, realizing the meshing of the drive gear 411 and the transmission gear 421. Simultaneously, the limiting rod 412 is inserted into the limiting hole 5211. After the limiting rod 412 is inserted into the limiting hole 5211, it abuts against the end of the second slide rod 522 located inside the first slide rod 521, limiting the sliding of the second slide rod 522. The supporting plate 413 abuts against the side of the transmission gear 421 away from the drive gear 411, and the supporting plate 413 supports and limits the axial movement of the rotating shaft 42. At this time, the stroke of the piston rod of the clamping cylinder 31 is the second stroke, which is shorter than the first stroke. Since the second slide rod 522 is fixed relative to the first slide rod 521 at this time, the piston rod of the clamping cylinder 31 extends to drive the sliding rod 52 to move downward. The second slide rod 522 abuts against the connecting plate 33. Since the connecting plate 33 and the rotating shaft 42 are ball jointed, the center line of the connecting plate 33 rotates relative to the axis of the rotating shaft 42, causing the entire connecting plate 33 to drive the clamping claw 32 and the denture to deflect relative to the rotating shaft 42. As a result, during the inspection process, the clamping claw 32 and the denture rotate around the axis of the rotating shaft 42 while also deflecting relative to the axis of the rotating shaft 42, further improving the detail and comprehensiveness of the inspection of various parts of the denture surface by the inspection component 7 and reducing blind spots in the inspection of the denture surface.

[0049] like Figure 1 and 4As shown, the system also includes a receiving assembly 6, which comprises a receiving slide rail 61, a first collection box 62, and a second collection box 63. The receiving slide rail 61 is fixedly connected to the detection point 14 of the work frame 1 and is located below the detection component 7. The first collection box 62 and the second collection box 63 are slidably connected to the receiving slide rail 61 and are respectively located on opposite sides of the work frame 1. Each of the first collection box 62 and the second collection box 63 contains a built-in drive source (not shown in the figure). The detection component 7 is electrically connected to the drive source via a PLC program. If the detection result is qualified, the component inside the detection component 7 sends a signal to the drive source of the first collection box 62. Upon receiving the signal, the component moves to directly below the clamping claw 32 for easy unloading. If the detection result is unqualified, the component inside the detection component 7 sends a signal to the drive source of the second collection box 63, which then moves to collect and centrally process the unqualified products. The recycling bin 62 includes a body 621, a first lid 622, and a second lid 623. Both lids 622 and 623 are hinged to the body 621. A discharge protrusion 624 is fixedly connected to the side of lids 622 and 623 that are close to each other. After inspection, the rotating motor 41 resets, the piston rod of the clamping cylinder 31 extends until the denture abuts against the discharge protrusion 624, driving the clamping claw 32 to open, and the piston rod of the clamping cylinder 31 retracts, causing the denture to disengage from the clamping claw 32. Under the action of the contact force and the denture's own weight, lids 622 and 623 rotate relative to the body 621, facilitating the smooth entry of the denture into the body 621.

[0050] The implementation principle of an automatic detection device for dentures according to an embodiment of this application is as follows:

[0051] After the denture is processed in the previous step, it is directly carried by the loading block 12 and moved along the loading groove 11. The loading slider 24 moves above the loading block 12, and the clamping cylinder 31 is activated. At this time, the piston rod of the clamping cylinder 31 extends its first stroke, driving the clamping claw 32 and the abutment ring 34 to move downward in alignment with the workpiece. The clamping claw 32 opens to clamp the denture, and the clamping claw 32 and the abutment ring 34 work together to fix the denture, reducing the possibility of the denture detaching from the clamping claw 32 during the inspection process.

[0052] When the denture moves to the inspection point 14, the rotating motor 41 moves closer to the loading beam 22, and the drive gear 411 meshes with the transmission gear 421, facilitating the rotation of the rotating shaft 42 driven by the rotating motor 41. The limiting rod 412 is inserted into the limiting hole 5211, fixing the second slide rod 522 relative to the first slide rod 521. At the same time, the supporting plate 413 abuts against the transmission gear 421, limiting the axial movement of the rotating shaft 42. The clamping cylinder 31 is activated, and its piston rod extends to the second stroke, driving the second slide rod 522 to abut against the connecting plate 33. This causes the connecting plate 33 to rotate with the rotating shaft 42 while simultaneously deflecting at an angle relative to the axis of the rotating shaft 42, further improving the precision of the inspection of the denture surface by the inspection component 7, reducing inspection data errors, and improving inspection accuracy.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
