Description

Technical Field

[0001] This invention relates to the field of automated assembly production equipment, and in particular to an automatic clamping and gluing machine for gluing pads and its gluing process. Background Technology

[0002] Clamps are fundamental components in industrial production and are suitable for a variety of applications. For example, in industrial production, when materials need to be clamped and fixed, the outer end of a robotic arm typically uses clamps as the actuating component to contact and grasp materials. Clamps can also be used as auxiliary tools such as pliers in daily life. The bare clamps are generally made of metal. To prevent damage to the material surface during the clamping and fixing process, the part of the clamp that contacts the material needs to be fitted with pads made of plastic materials such as tooth pads or black pads. The flexible material properties of the pads enable flexible contact during the clamping process, avoiding damage to the material surface.

[0003] Based on the clamp structure, the clamp production process involves the assembly of three materials: clamps, tooth pads, and black pads. Since the tooth pads and black pads are inserted into the clamps with an interference fit, a large pushing force is required to overcome the interference fit and forcefully push the tooth pads and black pads into the clamps. Traditional manual pushing and pressing is difficult and cannot guarantee the consistency of pressing depth, resulting in a low yield rate of tooth pads and black pads. Therefore, it is necessary to design an automatic clamping and pad installation machine. Summary of the Invention

[0017] An automatic clamping and automatic pad-filling process for an automatic pad-filling machine includes the following steps: S1. Feeding and guiding: Manually place the clamps, tooth pads and black pads into the corresponding vibratory feeders. The clamp vibratory feeder, tooth pad vibratory feeder and black pad vibratory feeder guide the clamps, tooth pads and black pads one by one into the clamp guiding assembly, tooth pad guiding assembly and black pad guiding assembly respectively. Then, guide them in a straight line into the clamp receiving assembly, tooth pad receiving assembly and black pad receiving assembly respectively. S2. Clamping Positioning and Transfer Loading: After the clamp enters the clamping groove of the clamp receiving assembly from the clamping guide assembly in step S1, the clamping ejector of the clamp receiving assembly pushes the clamping clamp in the opposite direction. After the clamping clamping member presses the clamping clamp from above by lifting and rotating, the clamping clamping block of the clamping and picking mechanism inserts from the sleeve of the clamping head and presses against the inner wall of the clamp from the inside to the outside to clamp the clamping clamp. Then, the clamping clamping member releases the clamping clamp, and the clamping and picking mechanism takes out the clamping clamp and moves it into the fixture, where it is clamped and fixed by the clamping assembly. S3. Dental pad receiving, side clamping positioning and removal: After the dental pad in step S1 enters the dental pad groove of the dental pad receiving assembly from the dental pad guiding assembly, it is pushed out by the dental pad ejector on the rear side, so that the front side of the dental pad extends outward from the dental pad groove and is in a suspended state. Then, the dental pad side clamps clamp and correct the dental pad from both sides. After the dental pad removal mechanism clamps and fixes the dental pad in the suspended state from the outside, the dental pad side clamps release the dental pad, and the dental pad removal mechanism removes the dental pad. S4.

Then, the black pad picking mechanism clamps and fixes the black pad from the suspended part and takes out the black pad. S6. Black pad assembly: After the black pad picking mechanism in step S5 takes out the black pad, the turntable mechanism drives the fixture after the tooth pad is assembled in step S4 to move to the black pad assembly position. The black pad picking mechanism moves the black pad to the black pad assembly position and inserts the black pad into the black pad groove of the clamp. S7. Assembly Inspection: After the black pad is assembled in step S6, the turntable mechanism drives the fixture to the inspection position. The inspection mechanism takes pictures to check whether the tooth pad and black pad are installed in place and feeds back the results to the industrial control computer. S8. Clamping and bending: After the assembly and inspection in step S7 is completed, the turntable mechanism drives the fixture to move to the bending station. The industrial control computer controls whether the bending mechanism performs the bending action according to the feedback result. If the inspection is passed, the bending action is performed and the clamping tongue is pressed to fix the black pad. If the inspection is not passed, the bending action is not performed. S9. Unloading: The clamping assembly in step S8 rotates from the bending position to the unloading position via a turntable. The clamping assembly releases its grip, and the industrial control computer controls the unloading mechanism at the unloading position to sort out the good and defective clamping assemblies and put them into different material boxes according to the detection results in step S7.

[0018] The beneficial effects of this invention are as follows: This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing an automatic clamping pad assembly machine and its pad assembly process. This machine enables automatic feeding, transfer, and receiving of clamps, tooth pads, and black pads, while simultaneously receiving materials and achieving clamping or positional offset suspension to ensure positional stability and avoidance of material voids during material handling. It also enables positional angle adjustment during the transfer of tooth pads and black pads, and achieves automatic insertion of tooth pads and black pads, as well as post-insertion inspection and bending. This improves the clamping assembly and quality of the machine.

[0019] This invention is applied to the field of automated production and assembly of clamps. It belongs to the category of automated equipment. Its function is to realize the automatic feeding, guiding, transfer and receiving, and picking of clamps, tooth pads and black pads, as well as the automatic insertion of tooth pads and black pads. After the tooth pads and black pads are assembled, the assembly is inspected, and the clamps that are assembled are automatically bent and tightened by classifying them, so as to improve the clamp assembly efficiency and the assembly yield.

[0020] Specifically, the invention uses a horizontally positioned machine platform as its supporting structure. The machine platform is equipped with a turntable mechanism, which uses the horizontally positioned turntable as its supporting plane. Along the circumferential direction, the turntable is spaced at clamping loading positions, tooth pad assembly positions, black pad assembly positions, inspection positions, bending positions, and unloading positions. Driven by a lower turntable motor, the turntable rotates one angle position at a time to switch between work positions. The clamping loading positions, tooth pad assembly positions, black pad assembly positions, inspection positions, bending positions, and unloading positions are respectively equipped with clamping feeding mechanisms, tooth pad assembly mechanisms, and other related mechanisms. The system includes a pad feeding mechanism, a black pad feeding mechanism, a detection mechanism, a bending mechanism, and a unloading mechanism. When the turntable rotates the fixture to the clamping and loading station, the clamps from the clamp feeding mechanism are taken out by the clamping and unloading mechanism and moved onto the fixture. The clamping components located below the fixture clamp and secure the clamps from both sides. The turntable then rotates the fixture to the pad assembly position. The pads from the pad feeding mechanism are taken out by the pad unloading mechanism and moved to the fixture, where they are inserted into the pad slots of the clamps. The turntable then rotates the clamps that assemble the pads. Moving to the black pad assembly position, the black pads fed by the black pad feeding mechanism are retrieved by the black pad picking mechanism and transferred to the fixture. The black pads are then inserted into the black pad slots of the clamps, assembling them into clamp components. The turntable rotates the assembled clamp components to the inspection position, where images are taken for inspection to screen for good and defective products. The OK signal for good products and the NG signal for defective products are sent to the industrial control computer. The industrial control computer then controls the bending mechanism to perform a bending action on the clamp components rotated to the bending position. For good clamp components… The bending action is performed on the part. The bending mechanism presses the pressure tongues on both sides of the black pad from a vertical state to a horizontal state, thereby tightening the black pad inside the clamp. For defective products, the bending action is not performed. After the clamping assembly at the bending position completes the station action, it is rotated to the unloading position by the turntable. After the clamping assembly is released from the clamping state, the unloading mechanism set at this position classifies and transports the clamping assembly into two boxes set at the unloading position according to the good or defective products after inspection. The assembled clamping assembly is automatically classified and unloaded.

[0021] Specifically, since the clamps need to rotate one angle position at a time with the turntable after being placed in the fixture to switch back and forth between different workstations, in order to ensure the positional stability of the clamps within the fixture during rotation and assembly, and to avoid interference when assembling the tooth pads and black pads, this invention provides a clamping assembly at the fixture. The clamping assembly is located below the turntable and is powered by a horizontally positioned clamping cylinder. Two L-shaped clamping blocks are located on the output end of the clamping cylinder, with their horizontal ends connected to the output end of the clamping cylinder and their outer ends extending vertically upwards, passing through a through slot on the turntable and extending upwards to the outside of the fixture. Driven by the clamping cylinder, the two clamping blocks clamp and fix the two sides of the head of the clamp, which is placed on the fixture and is in a suspended state, from the outside, thereby fixing and positioning the clamps to ensure their positional stability during transfer or assembly, and maintaining a clamped state during synchronous rotation with the fixture. Furthermore, by clamping and fixing from the outside, there will be no movement interference with the subsequent clamping and assembly of the tooth pads and black pads.

[0022] Furthermore, given the irregular structure of the clamps, tooth pads, and black pads, and the assembly process requirement that the tooth pads and black pads need to overcome the frictional forces of the interference fit and be forcibly inserted into the clamps, the first issue to be addressed is the problem of material feeding, guiding, and receiving / retrieving from the clamps by the feeding mechanism. Secondly, during the assembly of the tooth pads and black pads, the technical issues of removing and inserting them into the clamps need to be resolved. Specifically, when the tooth pads or black pads are discharged through the vibratory feeder and the guiding assembly and enter the receiving assembly for transfer, it is necessary to ensure that their removal from the receiving assembly does not interfere with subsequent insertion and assembly. Simultaneously, the positional accuracy of the tooth pads and black pads during material removal must be ensured for accurate subsequent insertion into the clamps.

[0023] Specifically, addressing the material feeding problem of the clamps, this invention designs a clamp feeding mechanism. After multiple clamps are placed into a vibratory feeder, the vibratory feeder guides each clamp to the clamp guiding assembly, which then guides each clamp to the clamp receiving assembly along a straight material path. A key feature is that, considering the irregular shape of the clamps and to avoid motion interference between the clamps and the clamping mechanism when placed on the fixture, this invention utilizes the structural feature of a through space within the clamp head, employing an internal clamping structure. This is achieved by providing a horizontally extending outward insert at the front end of the clamping block in the clamping mechanism. During the material handling process, after the inserts of the two clamping blocks are inserted into the through space of the clamping head, the clamping cylinder drives the two clamping blocks to tighten outward, thereby fixing the clamp against the inner wall of the clamp. After the clamping and material handling mechanism removes the clamp, it transports the clamp and places it on the fixture on the turntable. At this time, the clamping component under the fixture clamps the clamp from the outside, and the clamping blocks release the clamp and move to the clamp receiving component for the next clamping and material handling. This internal clamping and material handling method utilizes the structure of the clamp itself to complete the automatic clamping and placement without interfering with the clamping component at the fixture clamping and positioning the clamp from the outside. Furthermore, based on the clamping method, the clamping receiving assembly of this invention uses a vertically arranged clamping receiving cylinder to provide lifting power to drive the clamping receiving seat to move up and down. When clamping is required, the clamping receiving cylinder drives the clamping receiving seat to move up and down, aligning its clamping groove with the discharge port of the clamping guide assembly, allowing the clamp to slide into the clamping groove. After receiving the material, the clamping receiving seat moves upward, blocking the discharge port of the clamping guide assembly through its front side wall to prevent the clamp inside from continuing to exit. Simultaneously, since the clamping mechanism needs to insert into the clamp and then open and clamp outward, to ensure the positional stability of the clamp during the material receiving process, this invention has a clamping function during material receiving. The rear side of the clamping receiving seat uses a clamping receiving side support as a load-bearing structure. In this invention, when the clamp ejection cylinder on the material receiving side support drives the lifting seat to move the outer end of the rotating sleeve upward, the inner end of the rotating sleeve drives the clamping block downward, pressing and fixing the clamp in the clamping groove so that its position will shift when the clamp is removed. The vertical lifting force is converted into the downward pressure of the clamping block through the rotational connection of the rotating sleeve. This method of pressing from above in a rotating downward direction can achieve clamping while avoiding motion interference when the clamp enters the clamping groove. Furthermore, the rear side wall of the clamping groove of this invention is also provided with a clamp ejection cylinder. The clamp ejection cylinder horizontally drives the clamping rod to extend into the clamping groove to adjust and correct the clamp in the clamping groove, so as to ensure the position accuracy of the clamp during the material picking process.

[0024] Specifically, addressing the issues of dental pad feeding and retrieval, this invention designs a dental pad feeding mechanism. Multiple dental pads are placed into a dental pad vibratory feeder, which then guides them one by one into a dental pad guiding assembly. The guiding assembly guides the dental pads one by one along a straight feeding path to a dental pad receiving assembly, where they are then retrieved by a dental pad retrieval mechanism and inserted into the dental pad slots of the clamps. A key feature is that the dental pad receiving seat is driven to move up and down by a lower dental pad receiving cylinder. When a dental pad needs to be retrieved, the cylinder drives the first dental pad slot of the receiving seat to align with the outlet of the guiding assembly, allowing the dental pad to slide into the slot. After retrieval, the cylinder drives the receiving seat to continue moving upwards, causing the front wall of the receiving seat to block the outlet of the guiding assembly, preventing further feeding. Furthermore, the dental pad... The rear wall of the receiving seat is also equipped with a dental pad rear support. The rear support has a second dental pad groove, which is aligned with the first dental pad groove to support the dental pad. Both grooves have downwardly recessed insert grooves at their bottoms to receive the dental pad insert strip at the bottom of the dental pad. A dental pad ejection cylinder is horizontally mounted on the rear support. The receiving seat has multiple vertically extending inward air holes, which are connected to an external air passage through mounting holes. After the dental pad enters the receiving seat, to ensure the subsequent dental pad... The pad picking mechanism can grip the dental pad and push it out horizontally outward through the dental pad ejection cylinder, causing the head of the dental pad to slide outward and be suspended in the air so that the dental pad picking mechanism can clamp the dental pad from the suspended part. At the same time, to ensure the stability of the dental pad position during the ejection process, a downward vacuum negative pressure suction force is generated at the air hole to continuously attract the dental pad in the dental pad receiving seat, avoiding the dental pad position displacement or excessive ejection distance during the ejection process. After the dental pad picking mechanism clamps the dental pad, the vacuum negative pressure at the air hole is controlled to disappear. The air hole can be connected to an external vacuum generator through an air pipe or air pipe connector connected in the mounting hole. Furthermore, the two sides of the first dental pad groove are also horizontally opened with side clamping grooves. The dental pad side clamping cylinder set on the rear side of the dental pad receiving seat drives the dental pad side clamping block to pass through the side clamping groove from the outside and clamp the dental pad in the dental pad receiving seat from the side. The dental pad side clamping block performs side clamping positioning correction of the dental pad to ensure its positional stability, while also assisting in fixing the dental pad during the picking process. Similarly, the black pad receiving assembly of the present invention, while carrying and receiving the black pad, also has a rear push-out function, so that one side of the black pad is pushed out horizontally before the black pad is picked up, so that it is in a suspended state, making it easy for the black pad picking mechanism to clamp and fix the black pad from the suspended part; and has a vacuum adsorption function, which assists the black pad to maintain continuous downward adsorption through vacuum negative pressure during the black pad ejection process, so as to ensure the stability and accuracy of the position of the black pad during the ejection process and prevent it from slipping out of the black pad receiving seat.

[0025] Furthermore, considering the assembly process requirements of the dental pads and black pads, the dental pad picking mechanism and black pad picking mechanism of this invention both integrate lifting, lateral movement, rotation, and clamping functions. The lifting function realizes the picking and unloading of dental pads or black pads, and the rotation function completes the transfer of dental pads or black pads between the feeding mechanism and the fixture. That is, after the dental pad picking mechanism or black pad picking mechanism takes out the dental pad or black pad from the dental pad receiving assembly or black pad receiving assembly, it rotates to align the dental pad or black pad with the clamps on the turntable fixture so that the dental pad or black pad can be pushed horizontally into the clamps. At the same time, it also integrates a lateral movement drive function so that the dental pad or black pad can be pushed horizontally into the clamps after alignment with the clamps. Specifically, the dental pad picking mechanism of the present invention uses a vertically arranged dental pad picking column as a supporting structure. A dental pad picking support is vertically provided on the dental pad picking column. A dental pad picking motor provided on the rear side wall of the dental pad picking support drives the dental pad picking transmission belt to move up and down, so as to drive the dental pad picking lifting seat connected to the front side of the dental pad picking support to move up and down, thereby realizing picking or unloading. A dental pad picking transverse movement cylinder provided on the side wall of the dental pad picking lifting seat provides horizontal transverse power to drive the dental pad picking transverse movement seat provided thereon to move horizontally, providing transverse thrust during the dental pad insertion process. A dental pad picking rotary motor provided on the dental pad picking transverse movement seat provides rotational power in the horizontal plane, so as to drive the dental pad clamping cylinder below it to rotate in the horizontal plane, completing the transfer of the dental pad between the dental pad receiving assembly and the turntable fixture. The dental pad clamping cylinder drives the dental pad clamping block to clamp the dental pad fixed in the suspended part from the dental pad receiving assembly and pushes the dental pad into the clamp, completing the dental pad assembly.

[0088] Example 10: As Figure 43 As shown in the figure, as an embodiment of the present invention, the present invention discloses an automatic clamping and automatic pad-filling process for an automatic pad-filling machine, comprising the following process steps: S1. Feeding and guiding: Manually place the clamps, tooth pads and black pads into the corresponding vibratory feeders. The clamp vibratory feeder, tooth pad vibratory feeder and black pad vibratory feeder guide the clamps, tooth pads and black pads one by one into the clamp guiding assembly, tooth pad guiding assembly and black pad guiding assembly respectively. Then, guide them in a straight line into the clamp receiving assembly, tooth pad receiving assembly and black pad receiving assembly respectively. S2. Clamping Positioning and Transfer Loading: After the clamp enters the clamping groove of the clamp receiving assembly from the clamping guide assembly in step S1, the clamping ejector of the clamp receiving assembly pushes the clamping clamp in the opposite direction. After the clamping clamping member presses the clamping clamp from above by lifting and rotating, the clamping clamping block of the clamping and picking mechanism inserts from the sleeve of the clamping head and presses against the inner wall of the clamp from the inside to the outside to clamp the clamping clamp. Then, the clamping clamping member releases the clamping clamp, and the clamping and picking mechanism takes out the clamping clamp and moves it into the fixture, where it is clamped and fixed by the clamping assembly. S3. Dental pad receiving, side clamping positioning and removal: After the dental pad in step S1 enters the dental pad groove of the dental pad receiving assembly from the dental pad guiding assembly, it is pushed out by the dental pad ejector on the rear side, so that the front side of the dental pad extends outward from the dental pad groove and is in a suspended state. Then, the dental pad side clamps clamp and correct the dental pad from both sides. After the dental pad removal mechanism clamps and fixes the dental pad in the suspended state from the outside, the dental pad side clamps release the dental pad, and the dental pad removal mechanism removes the dental pad. S4. Dental pad assembly: After the dental pad picking mechanism takes out the dental pad in step S3, the turntable mechanism drives the fixture loaded with clamps in step S1 to move to the dental pad assembly position. The dental pad picking mechanism transports the picked-out dental pad to the dental pad assembly position and inserts it into the dental pad groove of the clamp. S5. Black pad receiving and picking up: After the black pad in step S1 enters the black pad groove of the black pad receiving component from the black pad guiding component, it is pushed outward by the cylinder set on the rear support of the black pad, so that its outer part is in a suspended state. Then, the black pad picking mechanism clamps and fixes the black pad from the suspended part and takes out the black pad. S6. Black pad assembly: After the black pad picking mechanism in step S5 takes out the black pad, the turntable mechanism drives the fixture after the tooth pad is assembled in step S4 to move to the black pad assembly position. The black pad picking mechanism moves the black pad to the black pad assembly position and inserts the black pad into the black pad groove of the clamp. S7. Assembly Inspection: After the black pad is assembled in step S6, the turntable mechanism drives the fixture to the inspection position. The inspection mechanism takes pictures to check whether the tooth pad and black pad are installed in place and feeds back the results to the industrial control computer. S8. Clamping and bending: After the assembly and inspection in step S7 is completed, the turntable mechanism drives the fixture to move to the bending station. The industrial control computer controls whether the bending mechanism performs the bending action according to the feedback result. If the inspection is passed, the bending action is performed and the clamping tongue is pressed to fix the black pad. If the inspection is not passed, the bending action is not performed. S9. Unloading: The clamping assembly in step S8 rotates from the bending position to the unloading position via a turntable. The clamping assembly releases its grip, and the industrial control computer controls the unloading mechanism at the unloading position to sort out the good and defective clamping assemblies and put them into different material boxes according to the detection results in step S7.

[0089] Furthermore, this invention designs an automatic clamping pad loading machine and its pad loading process that realizes automatic feeding, transfer and receiving of clamps, tooth pads and black pads, and simultaneously clamps or offsets the position during receiving to ensure positional stability and avoid empty space during material handling. It also realizes positional angle adjustment during the transfer of tooth pads and black pads, and realizes automatic insertion of tooth pads and black pads, as well as detection and bending after insertion, thereby improving the clamping assembly and quality.

[0090] This invention is applied to the field of automated production and assembly of clamps, belonging to the category of automated equipment. Its function is to achieve automatic feeding, guiding, transfer, and unloading of clamps, jaw pads, and black pads, as well as automatic insertion of jaw pads and black pads. After assembly, it performs post-assembly inspection and automatically bends and tightens the clamps' tongues to improve assembly efficiency and yield. Specifically, the invention uses a horizontally positioned machine platform as its support structure. The platform has a turntable mechanism, with the turntable serving as its support plane. The turntable is circumferentially spaced with clamp loading positions, jaw pad assembly positions, black pad assembly positions, inspection positions, bending positions, and unloading positions. Driven by a lower turntable motor, the turntable rotates one angle position at a time to switch between workstations. The clamp loading position, jaw pad assembly position, black pad assembly position, inspection position, bending position, and unloading position are respectively equipped with clamp feeding mechanisms, jaw pad assembly mechanisms, and other related equipment. The system includes a pad feeding mechanism, a black pad feeding mechanism, a detection mechanism, a bending mechanism, and a unloading mechanism. When the turntable rotates the fixture to the clamping and loading station, the clamps from the clamp feeding mechanism are taken out by the clamping and unloading mechanism and moved onto the fixture. The clamping components located below the fixture clamp and secure the clamps from both sides. The turntable then rotates the fixture to the pad assembly position. The pads from the pad feeding mechanism are taken out by the pad unloading mechanism and moved to the fixture, where they are inserted into the pad slots of the clamps. The turntable then rotates the clamps that assemble the pads. Moving to the black pad assembly position, the black pads fed by the black pad feeding mechanism are retrieved by the black pad picking mechanism and transferred to the fixture. The black pads are then inserted into the black pad slots of the clamps, assembling them into clamp components. The turntable rotates the assembled clamp components to the inspection position, where images are taken for inspection to screen for good and defective products. The OK signal for good products and the NG signal for defective products are sent to the industrial control computer. The industrial control computer then controls the bending mechanism to perform a bending action on the clamp components rotated to the bending position. For good clamp components… The bending action is performed on the part. The bending mechanism presses the pressure tongues on both sides of the black pad from a vertical state to a horizontal state, thereby tightening the black pad inside the clamp. For defective products, the bending action is not performed. After the clamping assembly at the bending position completes the station action, it is rotated to the unloading position by the turntable. After the clamping assembly is released from the clamping state, the unloading mechanism set at this position classifies and transports the clamping assembly into two boxes set at the unloading position according to the good or defective products after inspection. The assembled clamping assembly is automatically classified and unloaded.

[0091] Specifically, since the clamps need to rotate one angle position at a time with the turntable after being placed in the fixture to switch back and forth between different workstations, in order to ensure the positional stability of the clamps within the fixture during rotation and assembly, and to avoid interference when assembling the tooth pads and black pads, this invention provides a clamping assembly at the fixture. The clamping assembly is located below the turntable and is powered by a horizontally positioned clamping cylinder. Two L-shaped clamping blocks are located on the output end of the clamping cylinder, with their horizontal ends connected to the output end of the clamping cylinder and their outer ends extending vertically upwards, passing through a through slot on the turntable and extending upwards to the outside of the fixture. Driven by the clamping cylinder, the two clamping blocks clamp and fix the two sides of the head of the clamp, which is placed on the fixture and is in a suspended state, from the outside, thereby fixing and positioning the clamps to ensure their positional stability during transfer or assembly, and maintaining a clamped state during synchronous rotation with the fixture. Furthermore, by clamping and fixing from the outside, there will be no movement interference with the subsequent clamping and assembly of the tooth pads and black pads.

[0092] Furthermore, given the irregular structure of the clamps, tooth pads, and black pads, and the assembly process requirement that the tooth pads and black pads need to overcome the frictional forces of the interference fit and be forcibly inserted into the clamps, the first issue to be addressed is the problem of material feeding, guiding, and receiving / retrieving from the clamps by the feeding mechanism. Secondly, during the assembly of the tooth pads and black pads, the technical issues of removing and inserting them into the clamps need to be resolved. Specifically, when the tooth pads or black pads are discharged through the vibratory feeder and the guiding assembly and enter the receiving assembly for transfer, it is necessary to ensure that their removal from the receiving assembly does not interfere with subsequent insertion and assembly. Simultaneously, the positional accuracy of the tooth pads and black pads during material removal must be ensured for accurate subsequent insertion into the clamps. Specifically, addressing the material feeding problem of the clamps, this invention designs a clamp feeding mechanism. After multiple clamps are placed into a vibratory feeder, the vibratory feeder guides each clamp to the clamp guiding assembly, which then guides each clamp to the clamp receiving assembly along a straight material path. A key feature is that, considering the irregular shape of the clamps and to avoid motion interference between the clamps and the clamping mechanism when placed on the fixture, this invention utilizes the structural feature of a through space within the clamp head, employing an internal clamping structure. This is achieved by providing a horizontally extending outward insert at the front end of the clamping block in the clamping mechanism. During the material handling process, after the inserts of the two clamping blocks are inserted into the through space of the clamping head, the clamping cylinder drives the two clamping blocks to tighten outward, thereby fixing the clamp against the inner wall of the clamp. After the clamping and material handling mechanism removes the clamp, it transports the clamp and places it on the fixture on the turntable. At this time, the clamping component under the fixture clamps the clamp from the outside, and the clamping blocks release the clamp and move to the clamp receiving component for the next clamping and material handling. This internal clamping and material handling method utilizes the structure of the clamp itself to complete the automatic clamping and placement without interfering with the clamping component at the fixture clamping and positioning the clamp from the outside.Furthermore, based on the clamping method, the clamping receiving assembly of this invention uses a vertically arranged clamping receiving cylinder to provide lifting power to drive the clamping receiving seat to move up and down. When clamping is required, the clamping receiving cylinder drives the clamping receiving seat to move up and down, aligning its clamping groove with the discharge port of the clamping guide assembly, allowing the clamp to slide into the clamping groove. After receiving the material, the clamping receiving seat moves upward, blocking the discharge port of the clamping guide assembly through its front side wall to prevent the clamp inside from continuing to exit. Simultaneously, since the clamping mechanism needs to insert into the clamp and then open and clamp outward, to ensure the positional stability of the clamp during the material receiving process, this invention has a clamping function during material receiving. The rear side of the clamping receiving seat uses a clamping receiving side support as a load-bearing structure. In this invention, when the clamp ejection cylinder on the material receiving side support drives the lifting seat to move the outer end of the rotating sleeve upward, the inner end of the rotating sleeve drives the clamping block downward, pressing and fixing the clamp in the clamping groove so that its position will shift when the clamp is removed. The vertical lifting force is converted into the downward pressure of the clamping block through the rotational connection of the rotating sleeve. This method of pressing from above in a rotating downward direction can achieve clamping while avoiding motion interference when the clamp enters the clamping groove. Furthermore, the rear side wall of the clamping groove of this invention is also provided with a clamp ejection cylinder. The clamp ejection cylinder horizontally drives the clamping rod to extend into the clamping groove to adjust and correct the clamp in the clamping groove, so as to ensure the position accuracy of the clamp during the material picking process.

[0093] Specifically, addressing the issues of dental pad feeding and retrieval, this invention designs a dental pad feeding mechanism. Multiple dental pads are placed into a dental pad vibratory feeder, which then guides them one by one into a dental pad guiding assembly. The guiding assembly guides the dental pads one by one along a straight feeding path to a dental pad receiving assembly, where they are then retrieved by a dental pad retrieval mechanism and inserted into the dental pad slots of the clamps. A key feature is that the dental pad receiving seat is driven to move up and down by a lower dental pad receiving cylinder. When a dental pad needs to be retrieved, the cylinder drives the first dental pad slot of the receiving seat to align with the outlet of the guiding assembly, allowing the dental pad to slide into the slot. After retrieval, the cylinder drives the receiving seat to continue moving upwards, causing the front wall of the receiving seat to block the outlet of the guiding assembly, preventing further feeding. Furthermore, the dental pad... The rear wall of the receiving seat is also equipped with a dental pad rear support. The rear support has a second dental pad groove, which is aligned with the first dental pad groove to support the dental pad. Both grooves have downwardly recessed insert grooves at their bottoms to receive the dental pad insert strip at the bottom of the dental pad. A dental pad ejection cylinder is horizontally mounted on the rear support. The receiving seat has multiple vertically extending inward air holes, which are connected to an external air passage through mounting holes. After the dental pad enters the receiving seat, to ensure the subsequent dental pad... The pad picking mechanism can grip the dental pad and push it out horizontally outward through the dental pad ejection cylinder, causing the head of the dental pad to slide outward and be suspended in the air so that the dental pad picking mechanism can clamp the dental pad from the suspended part. At the same time, to ensure the stability of the dental pad position during the ejection process, a downward vacuum negative pressure suction force is generated at the air hole to continuously attract the dental pad in the dental pad receiving seat, avoiding the dental pad position displacement or excessive ejection distance during the ejection process. After the dental pad picking mechanism clamps the dental pad, the vacuum negative pressure at the air hole is controlled to disappear. The air hole can be connected to an external vacuum generator through an air pipe or air pipe connector connected in the mounting hole. Furthermore, the two sides of the first dental pad groove are also horizontally opened with side clamping grooves. The dental pad side clamping cylinder set on the rear side of the dental pad receiving seat drives the dental pad side clamping block to pass through the side clamping groove from the outside and clamp the dental pad in the dental pad receiving seat from the side. The dental pad side clamping block performs side clamping positioning correction of the dental pad to ensure its positional stability, while also assisting in fixing the dental pad during the picking process. Similarly, the black pad receiving assembly of the present invention, while carrying and receiving the black pad, also has a rear push-out function, so that one side of the black pad is pushed out horizontally before the black pad is picked up, so that it is in a suspended state, making it easy for the black pad picking mechanism to clamp and fix the black pad from the suspended part; and has a vacuum adsorption function, which assists the black pad to maintain continuous downward adsorption through vacuum negative pressure during the black pad ejection process, so as to ensure the stability and accuracy of the position of the black pad during the ejection process and prevent it from slipping out of the black pad receiving seat.

[0094] Furthermore, considering the assembly process requirements of the dental pads and black pads, the dental pad picking mechanism and black pad picking mechanism of this invention both integrate lifting, lateral movement, rotation, and clamping functions. The lifting function realizes the picking and unloading of dental pads or black pads, and the rotation function completes the transfer of dental pads or black pads between the feeding mechanism and the fixture. That is, after the dental pad picking mechanism or black pad picking mechanism takes out the dental pad or black pad from the dental pad receiving assembly or black pad receiving assembly, it rotates to align the dental pad or black pad with the clamps on the turntable fixture so that the dental pad or black pad can be pushed horizontally into the clamps. At the same time, it also integrates a lateral movement drive function so that the dental pad or black pad can be pushed horizontally into the clamps after alignment with the clamps. Specifically, the dental pad picking mechanism of the present invention uses a vertically arranged dental pad picking column as a supporting structure. A dental pad picking support is vertically provided on the dental pad picking column. A dental pad picking motor provided on the rear side wall of the dental pad picking support drives the dental pad picking transmission belt to move up and down, so as to drive the dental pad picking lifting seat connected to the front side of the dental pad picking support to move up and down, thereby realizing picking or unloading. A dental pad picking transverse movement cylinder provided on the side wall of the dental pad picking lifting seat provides horizontal transverse power to drive the dental pad picking transverse movement seat provided thereon to move horizontally, providing transverse thrust during the dental pad insertion process. A dental pad picking rotary motor provided on the dental pad picking transverse movement seat provides rotational power in the horizontal plane, so as to drive the dental pad clamping cylinder below it to rotate in the horizontal plane, completing the transfer of the dental pad between the dental pad receiving assembly and the turntable fixture. The dental pad clamping cylinder drives the dental pad clamping block to clamp the dental pad fixed in the suspended part from the dental pad receiving assembly and pushes the dental pad into the clamp, completing the dental pad assembly.
