Description

Technical Field

[0001] This application relates to the field of endoscope pressing technology, and in particular to an endoscope pressing device and pressing method. Background Technology

[0002] Currently, the lens and housing of automotive interior mirrors are assembled using an interference fit method, and the assembly process relies entirely on manual operation: the operator needs to pre-install the lens into the housing, and then manually press the lens into the housing to complete the assembly. This manual assembly method has the following problems: (1) Poor assembly consistency: It is difficult to achieve standardized operation by manually applying force, resulting in large fluctuations in assembly depth and position. (2) High assembly difficulty: The interference fit requires high assembly precision and force, and deviations are prone to occur during the entire manual operation. (3) Low yield rate of assembled interior mirrors: The manual operation is labor-intensive, and it is easy for the lens and housing to be damaged, contaminated with oil, fingerprints and dust, etc., resulting in a low product qualification rate, increasing customer complaints and complaints. Summary of the Invention

[0003] This application aims to at least solve one of the aforementioned technical problems existing in the prior art. Therefore, the purpose of this application is to provide an endoscope pressing device and pressing method that can solve the problem that existing endoscope assembly relies on manual labor, making standardized operation difficult and resulting in a low yield rate of assembled endoscopes.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] An endoscope pressing device, comprising:

[0006] Base;

[0007] A lens transfer mechanism, which is mounted on the base, is used to acquire the lens to be pressed and move the lens to be pressed to a designated position;

[0008] A lens identification and flipping mechanism is provided on the base to identify the orientation of the pressing surface of the lens to be pressed and to flip the lens to be pressed with the mounting surface facing down so that the pressing surface of the lens to be pressed is facing up.

[0009] A lens pressing mechanism includes a lens housing mechanism and a pressing execution mechanism disposed on the base. The lens housing mechanism is used to transport and fix the lens housing to be pressed, and the pressing execution mechanism is capable of pressing the lens to be pressed into the lens housing mechanism in at least one preset direction.

[0010] A control mechanism, which is connected to the lens transfer mechanism, the lens identification and flipping mechanism, the lens housing mechanism and the pressing execution mechanism respectively, is used to control the pressing process of the lens to be pressed.

[0011] According to some embodiments of this application, the pressing actuator includes a pressing frame, an adsorption mechanism, and a power component. The bottom of the pressing frame is provided with a pressing plate, the adsorption mechanism is provided on the pressing plate for adsorbing the lens to be pressed, and the power component is provided on the pressing frame for pressing the lens adsorbed by the adsorption mechanism into the lens housing mechanism along at least one preset direction.

[0012] According to some embodiments of this application, the power assembly includes a first cylinder, a second cylinder, and a third cylinder. The first cylinder is disposed on the pressing frame and is used to press the lens to be pressed along a first direction. There are two second cylinders disposed on both sides of the first cylinder and are used to press the lens to be pressed along a second direction. There are several third cylinders evenly distributed on both sides of the first cylinder and are used to press the lens to be pressed along a third direction.

[0013] According to some embodiments of this application, the output ends of the first cylinder, the second cylinder, and the third cylinder are respectively provided with pressing heads. The pressing head of the first cylinder can directly contact the lens to be pressed. The pressing plate is provided with a plurality of pressing holes. The pressing heads of the second cylinder and the third cylinder can pass through the pressing holes and contact the lens to be pressed, so as to realize the pressing of the lens to be pressed. The side of the pressing head that contacts the lens to be pressed is made of a material with cushioning capacity to prevent the lens to be pressed from being damaged during the pressing process.

[0014] According to some embodiments of this application, the lens pressing mechanism further includes a lens positioning mechanism. The lens positioning mechanism includes a positioning frame, a positioning cylinder, and a lens mold. The positioning frame is disposed on the base, and the lens mold is disposed on the positioning frame. The specifications of the lens mold match the specifications of the lens to be pressed. The positioning cylinder is disposed on the positioning frame, and the output end of the positioning cylinder can move toward the lens mold. The positioning cylinder is used to position the lens to be pressed placed in the lens mold and to calibrate the positional error of the lens to be pressed.

[0015] According to some embodiments of this application, the lens pressing mechanism further includes a pressing moving mechanism. The pressing moving mechanism includes a first moving component and a second moving component. The first moving component includes a connecting plate, which is connected to the pressing execution mechanism at a preset tilt angle. The first moving component is used to drive the pressing execution mechanism to move in the vertical direction. The second moving component is disposed on the base and connected to the first moving component, and is used to drive the first moving component and the pressing execution mechanism connected to it to move in the horizontal direction, so as to realize the movement of the pressing position of the lens to be pressed.

[0016] According to some embodiments of this application, the mirror housing mechanism includes a mirror housing tray, a mirror housing conveying mechanism, and a mirror housing pressing mechanism. The mirror housing conveying mechanism is disposed on the base and is used to drive the mirror housing tray to move along a preset path to the pressing position. The mirror housing tray is disposed on the mirror housing conveying mechanism and is used to place the mirror housing to be pressed. The mirror housing pressing mechanism is disposed on both sides of the mirror housing conveying mechanism and is used to apply a clamping force to the mirror housing to be pressed placed in the mirror housing tray during the pressing process to fix the position of the mirror housing to be pressed during the pressing process.

[0017] According to some embodiments of this application, the lens identification and flipping mechanism includes a flipping frame, an identification mechanism, a flipping mechanism, a flipping drive mechanism, and a lens flipping positioning mechanism. The flipping frame is disposed on the base, and the lens flipping positioning mechanism is disposed on the flipping frame for placing the lens to be identified and pressed. The identification mechanism is located above the flipping mechanism for identifying the front and back of the lens to be pressed. The flipping mechanism is used to clamp the lens to be pressed. The flipping drive mechanism is disposed on the flipping frame and connected to the flipping mechanism for driving the flipping mechanism to flip the lens to be pressed to the pressing surface.

[0018] An endoscope pressing method, using the aforementioned endoscope pressing equipment, includes:

[0019] The lens transfer mechanism moves the lens to be pressed to the lens identification and flipping mechanism. The lens identification and flipping mechanism identifies whether the pressing surface of the lens to be pressed is facing up. If the pressing surface is not facing up, the lens to be pressed is flipped 180° so that the pressing surface of the lens to be pressed is facing up.

[0020] The lens transfer mechanism moves the lens to be pressed with the pressing surface facing up to the lens pressing mechanism, and the lens housing mechanism conveys the lens housing to be pressed to the pressing position and fixes the lens housing to be pressed.

[0021] The pressing actuator acquires the lens to be pressed and presses it into the lens housing along a preset path and angle to complete the assembly.

[0022] According to some embodiments of this application, the lens identification and flipping mechanism determines whether the pressing surface is facing upward based on the brightness difference between the front and back sides of the lens to be pressed under a reflected light source. When the pressing surface is identified as facing upward, the pressing execution mechanism directly acquires the lens to be pressed and performs the pressing action.

[0023] The beneficial effects of this application are:

[0024] This application, by setting up a lens recognition and flipping device, automatically identifies the orientation of the pressing surface of the lens to be pressed and adjusts it when the pressing surface is not facing upwards. This avoids human defects such as fingerprints or scratches on the lens caused by manual adjustment, improving the cleanliness and yield of the endoscope product surface. At the same time, the lens pressing mechanism can press the lens to be pressed into the lens housing mechanism in different directions, ensuring the accuracy and stability of the pressing between the lens and the lens housing, meeting the assembly precision requirements of the interference fit. The entire pressing process is uniformly coordinated and controlled by the control mechanism, realizing the automation and standardization of the process from the recognition, flipping and pressing of the lens to be pressed, improving the consistency and efficiency of assembly, reducing reliance on manual operation and saving labor costs.

[0057] Reference Figures 1 to 17 The following are specific embodiments of this application.

[0058] Depend on Figure 1 and Figure 2As shown, this application provides an endoscope pressing device, including a base 100, and a lens transfer mechanism 200, a lens identification and flipping mechanism 300, a lens pressing mechanism 400, and a control mechanism (not shown) disposed on the base 100. The lens transfer mechanism 200 is used to acquire the lens 500 to be pressed and move the lens 500 to be pressed to a designated position. The lens identification and flipping mechanism 300 is used to identify the orientation of the pressing surface of the lens 500 to be pressed and to flip the lens 500 to be pressed with the mounting surface facing down so that the pressing surface of the lens 500 to be pressed is facing up. The lens pressing mechanism 400 includes a lens housing mechanism 410 and a pressing execution mechanism 420 disposed on the base 100. The lens housing mechanism 410 is used to transport and fix the lens housing 600 to be pressed. The pressing execution mechanism 420 is capable of pressing the lens 500 to be pressed into the lens housing mechanism 410 in at least one preset direction. The control mechanism is connected to the lens transfer mechanism 200, the lens identification and flipping mechanism 300, the lens housing mechanism 410 and the pressing execution mechanism 420 respectively, and is used to control the pressing process of the lens 500 to be pressed.

[0059] The pressing surface is the front side of the lens 500 to be pressed. The control mechanism is a PLC controller.

[0060] This application, by setting up a lens recognition and flipping device, automatically identifies the orientation of the pressing surface of the lens to be pressed and adjusts it when the pressing surface is not facing upwards. This avoids human defects such as fingerprints or scratches on the lens caused by manual adjustment, improving the cleanliness and yield of the endoscope product surface. At the same time, the lens pressing mechanism can press the lens to be pressed into the lens housing mechanism in different directions, ensuring the accuracy and stability of the pressing between the lens and the lens housing, meeting the assembly precision requirements of the interference fit. The entire pressing process is uniformly coordinated and controlled by the control mechanism, realizing the automation and standardization of the process from the recognition, flipping and pressing of the lens to be pressed, improving the consistency and efficiency of assembly, reducing reliance on manual operation and saving labor costs.

[0061] Depend on Figures 3 to 5 As shown, in some embodiments, the pressing actuator 420 includes a pressing frame 421, an adsorption mechanism 422, and a power assembly. The bottom of the pressing frame 421 is provided with a pressing plate 423. The adsorption mechanism 422 is provided on the pressing plate 423 for adsorbing the lens 500 to be pressed. The power assembly is provided on the pressing frame 421 for pressing the lens 500 adsorbed by the adsorption mechanism 422 into the lens housing mechanism 410 along at least one preset direction.

[0062] The adsorption mechanism 422 includes several suction cups, which are connected to a vacuum generator (not shown). The control mechanism controls the vacuum generator to generate a vacuum so that the suction cups adsorb the lens 500 to be pressed.

[0063] In some embodiments, the power assembly includes a first cylinder 424, a second cylinder 425, and a third cylinder 426. The first cylinder 424 is disposed on the pressing frame 421 and is used to press the lens 500 to be pressed along a first direction. There are two second cylinders 425 disposed on both sides of the first cylinder 424 and are used to press the lens 500 to be pressed along a second direction. There are several third cylinders 426 disposed on both sides of the first cylinder 424 and are used to press the lens 500 to be pressed along a third direction.

[0064] Depend on Figure 4 As shown, there are four third cylinders 426, arranged in pairs on both sides of the first cylinder 424. The first direction is relative to the side of the lens 500 to be pressed, meaning the first cylinder 424 acts horizontally on the side of the lens 500 to eliminate lateral gaps in the horizontal plane and achieve precise positioning. The second direction is oblique relative to the lens 500 to be pressed, acting at a preset angle to the vertical direction on the edge of the lens 500 to apply pre-tightening force before formal pressing, preventing the lens 500 from shifting or warping during the pressing process. The preset angle ranges from 75° to 85°, preferably 80°, and the specific value can be set according to actual production needs. The third direction is the vertical direction relative to the lens 500 to be pressed, that is, the third cylinder 426 acts on the pressing surface of the lens 500 to be pressed along its own vertical direction, in order to press the lens 500 to be pressed smoothly and vertically into the lens housing 600 to be pressed, thus completing the interference fit assembly.

[0065] Specifically, the output ends of the first cylinder 424, the second cylinder 425, and the third cylinder 426 are respectively provided with pressing heads. The first cylinder 424 is provided with a first pressing head (not shown), the second cylinder 425 is provided with a second pressing head 4251, and the third cylinder 426 is provided with a third pressing head 4261. The pressing plate 423 is provided with a plurality of pressing holes 4231. The second pressing head 4251 and the third pressing head 4261 can both pass through the pressing holes 4231 and contact the lens 500 to be pressed. The first pressing head can directly contact the lens 500 to be pressed, so as to realize the pressing of the lens 500 to be pressed.

[0066] When pressing the lens 500 to be pressed, the first pressing head is driven by the first cylinder 424, the second pressing head 4251 is driven by the second cylinder 425 to pre-press the lens 500 into the lens housing 600 to be pressed, and then the third pressing head 4261 is driven by the third cylinder 426 to press the lens 500 into the lens housing 600 to be pressed.

[0067] Preferably, the cross-section of the lens 500 to be pressed is wedge-shaped, with a narrow edge on one side and a thick edge on the other side. During pressing, the narrow edge of the lens 500 to be pressed is first pre-pressed into the lens housing 600 to be pressed through the first pressing head and the second pressing head 4251, and then the thick edge on the other side is pressed into the lens housing 600 to be pressed through the third pressing head 4261. This step-by-step pressing can reduce the initial pressing resistance and prevent the lens 500 to be pressed from breaking due to instantaneous high pressure. At the same time, it ensures that the thick edge bears the main pressing reaction force during pressing, thereby improving the reliability and structural strength of pressing.

[0068] Furthermore, the sides of the first pressing head, second pressing head 4251, and third pressing head 4261 that contact the lens 500 to be pressed are made of a cushioning material. This material is a soft, rubber-coated material, specifically polyurethane, thermoplastic elastomer, or silicone, preferably polyurethane. The cushioning material ensures that when the first pressing head 4251 and third pressing head 4261 contact the lens 500, the contact surface deforms into a surface contact after being subjected to force, preventing excessive local pressure from causing the lens 500 to crack and preventing damage to the lens 500 during the pressing process.

[0069] Depend on Figure 6 As shown, in some embodiments, the lens pressing mechanism 400 further includes a lens positioning mechanism 430, which includes a positioning frame 431, a positioning cylinder 432, and a lens mold 433. The lens pressing mechanism 400 also includes a first frame 440, which is fixedly mounted on the base 100. The positioning frame 431 is mounted on the first frame 440, and the lens mold 433 is mounted on the positioning frame 431. The specifications of the lens mold 433 match the specifications of the lens 500 to be pressed. The positioning cylinder 432 is mounted on the positioning frame 431, and its output end can move towards the lens mold 433. The positioning cylinder 432 is used to position the lens 500 placed in the lens mold 433 and to calibrate the positional error of the lens 500.

[0070] Specifically, the lens mold 433 has a groove structure extending along its length and is mounted on the positioning frame 431. The lens 500 to be pressed can be placed into the groove structure through the lens transfer mechanism 200. The outer contour of the lens 500 to be pressed matches the cavity of the groove structure so that the specifications of the lens 500 to be pressed can be determined. If it does not meet the preset pressing requirements, it is rejected. If it does meet the requirements, the output end of the positioning cylinder 432 applies a clamping force to one side of the lens 500 to be pressed, thereby positioning the lens 500 to be pressed and eliminating the positional deviation of the lens 500 during the feeding process. This ensures that it is in the preset reference position before pressing, thereby ensuring the repeatability and consistency of the subsequent pressing process.

[0071] In some embodiments, the lens pressing mechanism 400 further includes a pressing moving mechanism, which includes a first moving component 450 and a second moving component 460. The first moving component 450 is disposed on the first frame 440 and includes a connecting plate 451. The connecting plate 451 is connected to the pressing actuator 420 at a preset tilt angle. The first moving component 450 is used to drive the pressing actuator 420 to move vertically, i.e., along... Figure 3 The first moving assembly 450 reciprocates along the Z-axis. The second moving assembly 460 is mounted on the first frame 440 and connected to the bottom of the first moving assembly 450. Two second moving assemblies 460 are provided and symmetrically arranged on the left and right sides of the first moving assembly 450. The second moving assemblies 460 are synchronously driven to move the first moving assembly 450 and its connected pressing actuator 420 horizontally. Figure 3 The device reciprocates along the X-axis to move the lens to be pressed at the 500 pressing position.

[0072] The first moving component 450 is also provided with an electrical connection part 470 on one side. The electrical connection part 470 is used to connect with the control mechanism, thereby realizing the control mechanism to control the operation of the lens pressing mechanism 400.

[0073] Furthermore, the preset tilt angle between the connecting plate 451 and the pressing actuator 420 is 10°, that is, the connection angle between the connecting plate 451 and the pressing frame 421 is offset by 10° relative to the Z-axis direction, which can realize the angle adjustment of pressing the lens 500 into the lens housing.

[0074] Preferably, the first moving component 450 and the second moving component 460 are both servo motor modules and are connected to each other through a control mechanism, which can achieve precise control of the pressing position and accuracy, with a repeatability accuracy of ±0.01mm.

[0075] Depend on Figures 7 to 9 As shown, in some embodiments, the mirror housing mechanism 410 includes a mirror housing tray 411, a mirror housing conveying mechanism 412, and a mirror housing pressing mechanism 413. The mirror housing conveying mechanism 412 is mounted on the base 100 and is used to move the mirror housing tray 411 along a preset path to the pressing position. The mirror housing tray 411 is mounted on the mirror housing conveying mechanism 412 and is used to place the mirror housing 600 to be pressed. The mirror housing pressing mechanism is located on both sides of the mirror housing conveying mechanism 412 and is used to apply a clamping force to the mirror housing 600 placed in the mirror housing tray 411 during the pressing process to fix the position of the mirror housing 600 during the pressing process.

[0076] Specifically, the mirror housing conveying mechanism 412 is along... Figure 3The conveyor line is arranged in the X-axis direction and is located between two second moving components 460. The mirror housing mechanism 410 also includes a tray frame 414, on which two mirror housing trays 411 are fixedly installed. The distance between the two mirror housing trays 411 is set according to the specifications of the mirror housing 600 to be pressed, so as to adapt to products of different specifications.

[0077] The mirror housing clamping mechanism 413 includes a baffle 4131, a clamping cylinder 4132, and a clamping shaft 4133. The output end of the clamping cylinder 4132 is connected to the baffle 4131 through the clamping shaft 4133. The clamping cylinder 4132 is vertically set so that the baffle 4131 is set in the vertical direction in the initial state. When it is necessary to clamp the mirror housing 600 to be clamped, the clamping cylinder 4132 drives the clamping shaft 4133 to rotate, thereby causing the baffle 4131 to rotate downward by 90° in the vertical direction, thereby achieving the clamping of the mirror housing 600 to be clamped.

[0078] The clamping cylinder 4132 can be a commonly available lever cylinder. The shape of the baffle 4131 matches the contour of the mirror housing 600 to be pressed.

[0079] Two mirror housing clamping mechanisms 413 are provided and are located on one side of the mirror housing tray 411 respectively. The mirror housing clamping mechanism 413 can apply clamping force to the mirror housing 600 to be pressed and fix it on the mirror housing tray 411. It can ensure that the mirror housing 600 to be pressed does not move during pressing and ensure the pressing accuracy and the consistency of assembly.

[0080] Specifically, the lens housing clamping mechanism 413 and the lens positioning mechanism 430 are along Figure 3 The lenses are arranged side by side along the Y-axis to facilitate the pressing of the lens 500 and the lens housing 600, with the pressing position being the location of the lens housing pressing mechanism 413.

[0081] Depend on Figure 10 As shown, in some embodiments, the lens identification and flipping mechanism 300 includes a flipping frame 310, an identification mechanism 320, a flipping mechanism 330, a flipping drive mechanism 340, and a lens flipping positioning mechanism 350. The flipping frame 310 is disposed on the base 100, and the lens flipping positioning mechanism 350 is disposed on the flipping frame 310 for placing the lens 500 to be identified and pressed. The identification mechanism 320 is located above the flipping mechanism 330 for identifying the front and back sides of the lens 500 to be pressed. The flipping mechanism 330 is used to clamp the lens 500 to be pressed. The flipping drive mechanism 340 is disposed on the flipping frame 310 and connected to the flipping mechanism 330 for driving the flipping mechanism 330 to flip the lens 500 to be pressed to the pressing surface.

[0082] Specifically, the identification mechanism 320 is a camera, which can be fixedly mounted above the flipping mechanism 330 via an external frame. The flipping positioning mechanism 350 is configured as a groove structure capable of placing the lens 500 to be pressed and mounted. The flipping mechanism 330 includes two symmetrically arranged grippers located on both sides of the flipping positioning mechanism 350, and the flipping mechanism 330 can clamp both ends of the lens 500 to be pressed and mounted. The flipping drive mechanism 340 includes a flipping motor 341, a first transmission belt 342, a second transmission belt 345, a driving synchronous pulley 343, and a first driven synchronous pulley 344. The flipping motor 341 is fixedly connected to the flipping frame 310. The output end of the flipping motor 341 is connected to the driving synchronous pulley 343. The driving synchronous pulley 343 is connected to the first driven synchronous pulley 344 through the first transmission belt 342. The first driven synchronous pulley 344 is coaxially mounted with a transmission shaft 346. Both ends of the transmission shaft 346 are provided with driven groups. The driven groups include two second driven synchronous pulleys 347 and a second transmission belt 345 wound around the two second driven synchronous pulleys 347. The two second driven synchronous pulleys 347 in the same group are located on the same side of the flipping frame 310, and one of the second driven synchronous pulleys 347 is connected to the transmission shaft 346, while the other second driven synchronous pulley 347 is connected to the flipping mechanism 330. The drive shaft 346 is used to ensure that the left and right sides flipping actions are synchronized, so that the flipping mechanisms 330 on both sides maintain the same angular displacement and phase during the flipping process, avoiding uneven force or deflection on the lens 500 to be pressed.

[0083] Furthermore, the lens recognition flipping mechanism 300 is also equipped with a lifting cylinder 360, the output end of which is connected to the flipping positioning mechanism 350. Under the control of the control mechanism, the lifting cylinder can drive the flipping positioning mechanism 350 to reciprocate along the Z-axis.

[0084] The output end of the flipping motor 341 is connected to one end of the corresponding first transmission belt 342 via the active synchronous pulley 343. The two transmission belts are connected by a transmission shaft to achieve synchronous rotation. The other end of the first transmission belt 342 is connected to the corresponding gripper. When the lens 500 to be pressed needs to be flipped, the lifting cylinder 360 drives the flipping positioning mechanism 350 to move downward to reserve space for the flipping of the lens 500. Then, the flipping motor 341 is started, and the rotational power is transmitted to the gripper via the first transmission belt 342, thereby causing the gripped lens 500 to be pressed to be flipped 180° around its own horizontal axis, so that the pressing surface faces upward.

[0085] Depend on Figure 11As shown, in some embodiments, the lens transfer mechanism 200 includes a handling robot 210 and a transfer suction cup 220 disposed at its execution end. The handling robot 210 is fixedly disposed on the base 100 and has multiple degrees of freedom of motion, which can drive the transfer suction cup 220 to adsorb and transfer the lens 500 to be pressed in space.

[0086] Depend on Figures 12 to 16 As shown, in some embodiments, an endoscope pressing device of this application further includes a lens hopper mechanism 700, which is used to store lenses 500 to be pressed. The lens hopper mechanism 700 includes a hopper frame 710, and a first hopper transfer mechanism 720, a full hopper 730, an empty hopper 740, a second hopper transfer mechanism 750, and a lens lifting mechanism 760 disposed on the hopper frame 710.

[0087] The hopper frame 710 is fixedly mounted on the base 100. The full hopper 730 contains several lenses 500 to be pressed and mounted. The first hopper transfer mechanism 720 includes a first motor module 721, a push plate 722, and a transfer guide rail 723. The first motor module 721 is connected to the guide rail. The transfer guide rail 723 is mounted on the hopper frame 710 along the X-axis direction (i.e., the horizontal direction). The push plate 722 is slidably mounted on the transfer guide rail 723 and is connected to the output end of the first motor module 721. The push plate 722 can move along the transfer guide rail 723 under the drive of the first motor module 721 to push the full hopper 730 to the lens lifting mechanism 760.

[0088] In some embodiments, the lens lifting mechanism 760 includes a lifting motor module 761, a lifting guide rail 762, a lens lifting support plate 763, and a lens sensing photoelectric sensor 764. The lifting motor module 761 is fixedly mounted on the hopper frame 710. The lifting guide rail 762 is connected to the lifting motor module 761 along the Z-axis direction (i.e., the vertical direction). The lens lifting support plate 763 is slidably mounted on the lifting guide rail 762 and connected to the output end of the lifting motor module 761. The lens lifting support plate 763 can move along the lifting guide rail 762 under the drive of the lifting motor module 761, thereby lifting the lenses 500 to be pressed in sequence to the top of the material to be picked up position 770, which is located above the end of the lifting guide rail 762 that is away from the base 100 in the vertical direction. The lens sensor photoelectric 764 is located above the material waiting position 770. It is used to sense whether the lens lifting plate 763 is at the highest position. If it is at the highest position, the lens lifting plate 763 stops feeding material upward.

[0089] The second hopper transfer mechanism 750 is mounted on the hopper frame 710. The second hopper transfer mechanism 750 is positioned opposite to the first hopper transfer mechanism 720 and close to the lens lifting mechanism 760. The second hopper transfer mechanism 750 includes a hopper storage plate 751, a first hopper moving component 752, and a second hopper moving component 753. The hopper storage plate 751 is connected to the first hopper moving component 752. The first hopper moving component 752 can drive the hopper storage plate 751 to move along the X-axis. The second hopper moving component 753 is located below the first hopper moving component 752.

[0090] After all the lenses 500 to be pressed in the full material hopper 730 are removed, it becomes an empty material hopper 740. The empty material hopper 740 is housed in the material hopper receiving plate 751 and moves along the X-axis under the drive of the first material hopper moving component 752, reaching above the second material hopper moving component 753. The second material hopper moving component 753 is equipped with a positioning plate 7531 that can engage the empty material hopper 740. The positioning plate 7531 is connected to the output end of the second material hopper moving component 753. The output end of the second material hopper moving component 753 drives the positioning plate 7531 to move along the Z-axis, thereby causing the empty material hopper 740 to detach from the material hopper receiving plate 751, completing the extraction and removal of the empty material hopper 740.

[0091] Depend on Figure 17 As shown, this application also provides an endoscope pressing method, employing the aforementioned endoscope pressing equipment, including:

[0092] S100. Extract the lens to be pressed and perform the first positioning of the lens to be pressed: The handling robot 210 moves the transfer suction cup 220 to the material position 770. The transfer suction cup 220 picks up the lens 500 to be pressed located at the top and places the lens 500 to be pressed into the flip positioning mechanism 350. The flip mechanism 330 clamps the lens 500 to be pressed to achieve the first positioning of the lens 500 to be pressed.

[0093] S200 Identification and flipping of the lens to be pressed: The identification mechanism 320 identifies whether the pressing surface of the lens 500 to be pressed is facing up. If the pressing surface is not facing up, the lens 500 to be pressed is flipped 180° so that the pressing surface of the lens 500 to be pressed is facing up.

[0094] Specifically, if the pressing surface is not facing upwards, the lifting cylinder 360 drives the flipping positioning mechanism 350 to move downwards in the vertical direction, providing space for subsequent lens flipping. The flipping motor 341 is started to drive the active synchronous pulley 343 to rotate, which in turn drives the first driven synchronous pulley 344 to rotate, so that the flipping mechanism 330 flips the lens 500 to be pressed 180° around its own horizontal axis, so that the pressing surface faces upwards. Then, the lifting cylinder 360 drives the flipping positioning mechanism 350 to move upwards in the vertical direction, so that the flipped lens 500 to be pressed is placed in the flipping positioning mechanism 350.

[0095] S300, Second Positioning of the Lens to be Pressed: The handling robot 210 uses the transfer suction cup 220 to pick up the lens 500 to be pressed again and moves it into the lens mold 433. The positioning cylinder 432 then performs a second positioning of the lens 500. If the lens 500 does not meet the assembly specifications, it is directly discarded. Lenses 500 that meet the specifications can directly undergo the second positioning. The second positioning is to ensure that the shape of the lens to be pressed meets the corresponding processing accuracy.

[0096] S400, Conveying and fixing the mirror housing to be pressed: The mirror housing conveying mechanism 412 conveys the mirror housing 600 to be pressed to the assembly position. At the same time, the clamping cylinder 4132 drives the clamping shaft 4133 to rotate the baffle 4131 downward by 90°, so that it applies clamping force to both ends of the mirror housing 600 to be pressed and fixes it.

[0097] S500, the lens pressing mechanism presses the endoscope housing and the lens to be pressed: the first moving component 450 and the second moving component 460 drive the adsorption mechanism 422 to adsorb the lens 500 to be pressed located in the lens mold 433 and move it to the vicinity of the endoscope housing 600. The first cylinder 424 and the second cylinder 425 are activated to pre-press the narrow edge of the lens 500 into the endoscope housing 600 at a preset angle. Then, the third cylinder 426 is activated to press the thick edge of the lens 500 into the endoscope housing 600, thus completing the pressing of the endoscope.

[0098] The endoscope pressing method of this application realizes automatic feeding of the lens to be pressed through the lens hopper mechanism, and realizes automatic front and back recognition and error correction of the lens to be pressed through the lens recognition and flipping mechanism. The lens to be pressed is first positioned and second positioned in sequence to ensure that the lens to be pressed can meet the processing accuracy. Then, the first moving component, the second moving component and the pressing execution mechanism coordinate their actions to realize the automatic pressing of the lens to be pressed and the lens housing to be pressed, thereby improving production efficiency and ensuring product quality.

[0099] In some embodiments, the identification mechanism 320 determines whether the pressing surface is facing upward based on the brightness difference between the front and back surfaces of the lens 500 to be pressed under a reflected light source. Specifically, the front surface of the lens 500 to be pressed is a silver mirror surface, and the back surface is a protective surface. The silver mirror surface and the protective film surface have a large difference in reflectivity. The identification mechanism 320 detects this difference by measuring the brightness difference of the reflected light source between the two surfaces. When the pressing surface is detected to be facing upward, the pressing execution mechanism directly acquires the lens to be pressed and performs the pressing action.

[0100] This application discloses an endoscope pressing device and method. By setting a lens transfer mechanism, a lens identification and flipping mechanism, a lens pressing mechanism, and a lens hopper mechanism on a base, it achieves automatic feeding, identification, and positioning of the lenses and lens housings to be pressed, as well as interference fit between the lenses and lens housings. Before pressing, the lens identification and flipping mechanism identifies and adjusts the assembly surface of the lens to be pressed and places the lens in the lens positioning mechanism for secondary positioning, ensuring assembly consistency and improving assembly accuracy. The first and second moving components are connected to the pressing execution mechanism to achieve precise control of the pressing path and angle. The first, second, and third cylinders are set to pre-press the lens in different directions before overall pressing, improving the reliability and structural strength of the pressing. The entire pressing process is controlled by a control mechanism, eliminating the need for manual intervention in the actual pressing steps, avoiding damage to the lens and lens housing, contamination with oil, fingerprints, and dust, improving the yield rate of the assembled endoscope, and achieving higher customer satisfaction.
