Description

Technical Field

[0001] This utility model belongs to the field of automated assembly equipment technology, and in particular relates to a rubber ring installation device. Background Technology

[0002] Currently, SIM card trays used in digital devices such as mobile phones and smartwatches generally employ a waterproof rubber ring structure to meet the requirements of daily water and dust resistance. By fitting the rubber ring into a specific slot on the SIM card tray, it ensures a tight fit with the device's casing, effectively preventing liquid intrusion. This waterproof design effectively prevents light rain, splashes, or dust from seeping into the electronic device through the side gap between the SIM card tray and the casing during daily use.

[0003] However, the assembly process for existing Casio waterproof gaskets still relies primarily on manual operation or semi-automated equipment, which presents significant technical shortcomings. Manual assembly depends on operator experience and suffers from low efficiency (long time per unit), poor consistency (uneven gasket dimensions), and high labor costs. While semi-automated equipment can partially replace manual labor, its structural complexity and functional integration limit its investment costs, maintenance difficulties, and insufficient production line flexibility, making it difficult to meet the current consumer electronics industry's demand for "high efficiency, low cost, and large-scale" production. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber ring installation device and a rubber ring installation method, which aims to solve the problems of low production efficiency, high labor costs, poor assembly consistency, and difficulty in meeting the needs of large-scale rapid model changeover caused by the use of manual or semi-automatic assembly methods in the prior art.

[0005] In a first aspect, this utility model provides a rubber ring installation device for assembling a rubber ring onto a card holder, the rubber ring installation device comprising: The control console includes a support frame, a support rod, and a positioning block, all of which are fixed to the table surface of the control console. The vibratory feeder, fixed to the control console by the positioning block, is used to accommodate the rubber ring and to convey the rubber ring in an orderly manner according to a preset direction by vibration. The robotic arm assembly, located on one side of the vibratory feeder, is fixed to the control console by the positioning block. It includes a robotic arm and an adsorption head located at the end of the robotic arm. The robotic arm is used to control the rotation and movement of the robotic arm assembly, and the adsorption head is used to pick up the rubber rings conveyed by the vibratory feeder. The rubber ring positioning seat is located below the robotic arm assembly. The rubber ring positioning seat is movably mounted on the support frame and can move and rotate horizontally relative to the control console. It is used to carry multiple rubber rings picked up by the suction head and to transport the multiple rubber rings to a preset position. The rubber ring picking module, located on the left side of the rubber ring positioning seat, is fixed to the control console by the support frame. It includes a retractable and openable opening and closing part and a support pin fixed to the end of the opening and closing part. When the opening and closing part is in the retracted state, the support pin is used to insert into the inner diameter of the rubber ring located at a preset position to pick up the rubber ring. When the opening and closing part is in the open state, the support pin expands radially to stretch the rubber ring to a preset size. A card tray positioning seat is disposed opposite to the rubber ring picking module. The card tray positioning seat is movably disposed on the support frame and can move horizontally relative to the control console. It includes a card tray groove for fixing the card tray. The card tray includes a card tray rubber ring groove and a card tray door plate. The card tray door plate is located at the outer edge of the card tray rubber ring groove. The expanded rubber ring passes through the card tray door plate and is directly assembled into the card tray rubber ring groove.

[0006] In some embodiments, the vibratory feeder includes at least a planar flexible vibratory feeder and a track-type directional vibratory feeder. The planar flexible vibratory feeder includes a flexible vibration table, a vibration drive assembly, and a material receiving cavity. The vibration drive assembly drives a rubber ring with a symmetrical structure to be orderly conveyed from the flexible vibration table to the material receiving cavity. The track-type directional vibratory feeder includes a rigid vibration base, a spiral ascending track, a direction recognition and adjustment mechanism, and a rigid screen. The rigid vibration base generates directional vibration, driving the rubber ring with an asymmetrical structure to be orderly conveyed along the spiral ascending track to the rigid screen. The direction recognition and adjustment mechanism is used to detect and adjust the attitude of the rubber ring during the conveying process.

[0007] In some embodiments, the adsorption head is frustum-shaped and uses vacuum adsorption to adsorb rubber rings of different specifications. The adsorption surface of the adsorption head has an arc-shaped structure that matches the outer surface of the rubber ring.

[0008] In some embodiments, the rubber ring pickup module further includes a driving unit and a rotating shaft. The driving unit is used to drive the rubber ring pickup module to rotate around the rotating shaft. When the opening and closing part is in the closed state, the driving unit drives the rubber ring pickup module to rotate 90° around the rotating shaft to pick up the rubber ring from the rubber ring positioning seat.

[0009] In some embodiments, the rubber ring positioning seat includes a plurality of rubber ring positioning grooves, the size of which is adapted to the outer diameter of the rubber ring, for supporting and positioning the plurality of rubber rings, and the number of the rubber ring positioning grooves is adapted to the number of the opening and closing portions and the number of the card holder rubber ring grooves.

[0010] In some embodiments, one of the opening and closing portions of the rubber ring pickup module is provided with four support pins, which are evenly distributed in a rectangular shape and are used to expand the rubber ring from multiple directions when the opening and closing portion is opened.

[0011] In some embodiments, the opening and closing portion includes a set of symmetrically arranged elastic clamping arms. The elastic clamping arms have a trapezoidal structure that is narrower at the front and wider at the back. When the opening and closing portion is in a closed state, the symmetrically arranged elastic clamping arms move closer to each other. When the opening and closing portion is in an open state, the symmetrically arranged elastic clamping arms move further apart from each other.

[0012] In some embodiments, when the opening and closing part is in the open state, the support pin expands the rubber ring to a preset size. The preset size is pre-set according to the structure of the card tray door panel to avoid the rubber ring colliding with the edge of the card tray door panel and to ensure that the rubber ring is smoothly installed into the card tray rubber ring groove.

[0013] In some embodiments, a first guide rail and a second guide rail are included. Both the first guide rail and the second guide rail are fixed to the console by the support frame. The first guide rail and the second guide rail are arranged parallel to each other. The rubber ring positioning seat is slidably mounted on the first guide rail and reciprocates along the direction of the first guide rail. The card tray positioning seat is slidably mounted on the second guide rail and reciprocates along the direction of the second guide rail.

[0014] In some embodiments, a lens detection module is also included. The lens detection module is fixed to the console via the support rod and is used to detect the position of the rubber ring after it has been assembled into the rubber ring groove of the card holder, so as to determine whether the rubber ring is assembled in place or whether there are any defects.

[0015] This utility model provides a rubber ring installation device. The device replaces the traditional manual one-by-one operation or the intermittent operation mode of semi-automatic equipment with a collaborative design of vibratory feeder directional feeding, robotic arm precise picking and placing, rubber ring positioning seat buffer conveying, rubber ring picking module controllable picking and opening, and card tray positioning seat high-precision assembly. This realizes the automated assembly of rubber rings, thereby greatly improving the assembly accuracy and production efficiency of rubber rings and significantly reducing labor costs.

[0020] This utility model provides a rubber ring installation device 1 for assembling a rubber ring 2 onto a card holder 3. Please refer to the following: Figures 1 to 9 The rubber ring installation device 1 includes a control console 10, a vibratory plate 11, a robotic arm assembly 12, a rubber ring positioning seat 13, a rubber ring picking module 14, and a card tray positioning seat 15. The control console 10 includes a support frame, a support rod, and a positioning block, all of which are fixed to the table surface of the control console 10. A vibratory feeder 11 is fixed to the control console 10 via the positioning block, used to accommodate rubber rings 2 and to convey them in an orderly manner according to a preset direction through vibration. A robotic arm assembly 12, located on one side of the vibratory feeder 10, is fixed to the control console 10 via the positioning block. The robotic arm assembly 12 includes a robotic arm 121 and a suction head 122 located at the end of the robotic arm 121. The robotic arm 121 controls the rotation and movement of the robotic arm assembly 12, and the suction head 122 picks up the rubber rings conveyed by the vibratory feeder 11. A rubber ring positioning seat 13, located below the robotic arm assembly 12, is movably mounted on the support frame and can move and rotate horizontally relative to the control console 10. It is used to carry multiple rubber rings 2 picked up by the suction head 122 and convey them to a preset position. The rubber ring pickup module 14, located on the left side of the rubber ring positioning seat 13, is fixed to the control console 10 by a support frame. The rubber ring pickup module 14 includes a retractable and openable opening and closing part 141 and a support pin 142 fixed to the end of the opening and closing part 141. When the opening and closing part 141 is in the retracted state, the support pin 142 is used to penetrate the inner diameter of the rubber ring 2 located at a preset position to pick up the rubber ring 2. When the opening and closing part 141 is in the open state, the support pin 142 expands radially to pick up the rubber ring. 2. The card tray positioning seat 15, which is positioned opposite to the rubber ring picking module 14 and is opened to a preset size, is movably mounted on the support frame and can move horizontally relative to the control console 10. The card tray positioning seat 15 includes a card tray groove 151 for fixing the card tray 2. The card tray 3 includes a card tray rubber ring groove 31 and a card tray door plate 32. The card tray door plate 32 is located at the outer edge of the card tray rubber ring groove 31. The opened rubber ring 2 passes through the card tray door plate 32 and is directly assembled into the card tray rubber ring groove 31. This utility model embodiment realizes fully automated assembly from rubber ring feeding, positioning, transfer, opening to final assembly through the coordinated operation of the vibratory feeder, robotic arm assembly, rubber ring positioning seat and rubber ring picking module, solving the problems of low efficiency, poor accuracy and high cost of traditional manual or semi-automatic assembly.

[0021] In some embodiments, the console 10 is a cubic or cuboid frame structure used to fix and support the vibratory feeder 11, the robotic arm assembly 12, the rubber ring positioning seat 13, the rubber ring pickup module 14, and the card tray positioning seat 15. The console 10 includes a support frame, support rods, and positioning blocks. The support rods and positioning blocks are fixed to the table surface of the console 10 and are used to provide stable support and positioning for different components. The support frame can be configured as a cubic or cuboid frame shape, selected according to the size, shape, and installation position of each component. A pair of opposite sides are completely open, forming a through-type double-opening structure. The support rods are slender cylindrical rod structures, and the positioning blocks are rectangular block structures.

[0022] In some embodiments, the vibratory feeder 11 includes at least a planar flexible vibratory feeder 111 and a track-type directional vibratory feeder (not shown). The planar flexible vibratory feeder 11 includes a flexible vibration table 1111, a vibration drive assembly 1112, and a material receiving cavity 1113. The vibration drive assembly 1112 drives a rubber ring with a symmetrical structure to be orderly conveyed from the flexible vibration table 1111 to the material receiving cavity 1113. The track-type directional vibratory feeder includes a rigid vibration base, a spiral rising track, a direction recognition and adjustment mechanism, and a rigid screen. The rigid vibration base generates directional vibration, driving the rubber ring with an asymmetrical structure to be orderly conveyed along the spiral rising track to the rigid screen. The direction recognition and adjustment mechanism is used to detect and adjust the attitude of the rubber ring during the conveying process.

[0023] In some embodiments, please refer to the reference Figure 3 The planar flexible vibratory feeder 111 includes a flexible vibratory table 1111, a vibration drive assembly 1112, and a material receiving cavity 1113. The flexible vibratory table 1111 is made of highly elastic and wear-resistant material, and is an open material receiving cavity with a flat bottom and low edges to accommodate a batch of rubber rings 2. Vibration causes the rubber rings 2 to move towards the discharge end. The flexible vibratory table 1111 has a smooth surface and a certain degree of flexible deformation capability. The vibration drive assembly 1112 can generate multi-directional composite vibrations, allowing the symmetrically structured rubber rings 2 placed on it to achieve a disordered to ordered movement adjustment under the vibration. The material receiving cavity 1113 is located below the flexible vibratory table 1111 and is connected to it. Its inner wall has a sloping structure to assist in the posture adjustment and orderly output of the rubber rings 2.

[0024] The track-type directional vibratory feeder (not shown) includes a rigid vibratory base, a spiral ascending track, a direction recognition and adjustment mechanism, and a rigid screen. The rigid vibratory base contains an eccentric vibration source that generates directional vibration energy to drive the spiral ascending track. The spiral ascending track extends upwards in a spiral shape along the inner wall of the rigid vibratory base. The track width is adapted to the structure of the asymmetrical rubber ring 2, allowing it to gradually achieve initial posture alignment during vibratory ascent. The direction recognition and adjustment mechanism is located in the middle section of the spiral ascending track and includes a recognition component and a straightening device. The recognition component detects the posture of the passing rubber ring 2. When the posture of the asymmetrical rubber ring 2 does not meet the preset requirements, the straightening device will directionally adjust it. The rigid screen is located at the top of the spiral ascending track and is used to temporarily store the rubber ring 2 to be transported.

[0025] In some embodiments, please refer to Figure 4 The robotic arm assembly 12 includes a robotic arm 121 and an adsorption head 122 disposed at the end of the robotic arm 121. The robotic arm 121 is used to control the rotation and movement of the robotic arm assembly 12, and the adsorption head 122 is used to pick up the rubber rings conveyed by the vibratory feeder 11.

[0026] In some embodiments, the robotic arm 121 is a multi-degree-of-freedom articulated robotic arm, which includes at least a rotation axis, a horizontal movement axis and a vertical lifting axis. Each axis is driven by a servo motor and can achieve 360° rotation and movement, rotation and attitude adjustment in three-dimensional space.

[0027] In some embodiments, please refer to Figure 5 The adsorption head 122 is frustum-shaped and uses vacuum adsorption to adsorb rubber rings of different specifications. The adsorption surface 1221 of the adsorption head 122 has an arc-shaped structure adapted to the outer surface of the rubber ring. The arc-shaped structure is an adaptively adjustable flexible curved surface that can fit the outer surface of the rubber ring, ensuring adsorption sealing while avoiding damage to the rubber ring from rigid contact. The edges of the arc-shaped surface have rounded transitions to eliminate stress concentration points, making it compatible with the adsorption of thin and irregularly shaped rubber rings and preventing the edges of the rubber ring from curling or deforming during adsorption. The outer periphery of the arc-shaped structure is also uniformly distributed with micro-adsorption holes 1222, which are arrayed radially and circumferentially along the arc-shaped surface. The adsorption holes 1222 are used to form a multi-point, uniform negative pressure adsorption channel between the arc-shaped structure and the outer surface of the rubber ring, so as to stably adsorb and maintain the position and posture of rubber rings of different specifications, preventing slippage or detachment.

[0028] In some embodiments, please refer to Figure 6The rubber ring positioning seat 13 includes multiple rubber ring positioning grooves 131. The size of the rubber ring positioning grooves 131 is adapted to the outer diameter of the rubber ring 2, and is used to support and position multiple rubber rings 2. The number of rubber ring positioning grooves 131 is adapted to the number of opening and closing parts 141 and the number of card holder rubber ring grooves 31, ensuring that multiple rubber rings 2 can be processed simultaneously in one operation, achieving efficient synchronous assembly. The cross-sectional shape of the rubber ring positioning groove 131 matches the outer contour of the rubber ring 2. When the rubber ring 2 is a standard circular ring, the cross-section of the positioning groove 131 is circular. When the rubber ring 2 has an irregular cross-section, the cross-section of the positioning groove 131 is a corresponding non-circular contour, such as D-shaped, rectangular with rounded corners, etc. The groove depth of the rubber ring positioning groove 131 is 1 / 2 to 2 / 3 of the thickness of the rubber ring 2, which not only forms a radial limit on the rubber ring 2 through the groove wall to prevent horizontal displacement, but also retains the exposed top area to facilitate the picking up by the opening and closing part 141 and the placement operation of the suction head 122. The number of rubber ring positioning grooves 131 is matched with the number of opening and closing parts 141 and the number of card holder rubber ring grooves 31. If there are 4 opening and closing parts 141, then there must also be 4 rubber ring positioning grooves 131 to ensure that each rubber ring on the rubber ring positioning seat 13 can be picked up by the corresponding opening and closing part 141.

[0029] In some embodiments, please refer to Figure 7 The rubber ring pickup module 14 includes an opening / closing part 141 and a support pin 142 fixed to the opening / closing part 141. The opening / closing part 141 includes a set of symmetrically arranged elastic clamping arms 1411, which have a trapezoidal structure that is narrower at the front and wider at the back. When the opening / closing part 141 is in the closed state, the symmetrically arranged elastic clamping arms 1411 approach each other, with the distance between their tips smaller than the outer diameter of the rubber ring 2. This causes the two sets of elastic clamping arms 1411 to approach and converge, thereby causing the support pin 142 fixed at its end to converge into a smaller diameter, which then penetrates the inner diameter of the rubber ring 2 located on the rubber ring positioning seat 13, achieving reliable pickup. When the opening / closing part 141 is in the open state, the symmetrically arranged elastic clamping arms 1411 move away from each other, directly causing the support pin 142 to expand radially. The support pin 142 provides radial limiting for the inner diameter of the rubber ring 2, preventing the rubber ring 2 from sliding axially or falling off during pickup, and evenly expanding the rubber ring 2 fitted onto it to the preset size required for assembly.

[0030] In some embodiments, an opening and closing portion 141 of the rubber ring pickup module 14 is equipped with four support pins 142. The four support pins 142 are evenly distributed in a rectangle and are used to expand the rubber ring 2 from multiple directions when the opening and closing portion 141 opens. The fixed positions of the four support pins 142 form a geometric layout of the four vertices of a rectangle at the top of the opening and closing portion 141, with equal spacing between adjacent pins. This ensures that when the opening and closing portion 141 opens, the four support pins 142 can expand synchronously and symmetrically in all directions, applying a uniform radial force to the inner wall of the rubber ring 2, avoiding deformation or tearing of the rubber ring 2 caused by local stress concentration. The top of the support pin 142 can be designed as a rounded chamfer or a tapered guide head to facilitate smoother insertion into the inner diameter of the rubber ring 2 and reduce frictional resistance and the risk of damage to the inner hole during insertion. The top planes of the four support pins 142 must be on the same horizontal plane to ensure that the force points of each pin are in the same plane when inserting into the inner diameter of the rubber ring 2, further improving the uniformity of force during expansion. The bottom end of the support pin 142 is rigidly connected to the top end of the elastic clamping arm 1411 by means of welding, threaded connection, interference fit, or embedded fixing. After fixing, the support pin 142 and the clamping arm 1411 move synchronously. When the clamping arm 1411 closes, the support pin 142 moves closer to the top end of the clamping arm. When the clamping arm 1411 opens, the support pin 142 moves away from the top end of the clamping arm.

[0031] In some embodiments, when the opening / closing part 141 is in the open state, the support pin 142 expands the rubber ring 2 to a preset size. The preset size is pre-set according to the structure of the card holder door panel 32 to avoid the rubber ring 2 colliding with the edge of the card holder door panel 32 and to ensure that the rubber ring 2 is smoothly installed into the card holder rubber ring groove 31. This preset size is slightly larger than the length of the card holder door panel 32 and matches the inner diameter of the card holder rubber ring groove 31, ensuring that the expanded rubber ring 2 can pass through the assembly space below the card holder door panel 32 without interference, effectively preventing the rubber ring from falling off or assembly failure due to collision. When the support pin 142 retracts and resets, the rubber ring 2 can retract by its own elasticity and fall into the card holder rubber ring groove 31 to form a tight fit, ultimately achieving efficient and non-destructive automated assembly.

[0032] In some embodiments, the rubber ring pickup module 14 further includes a drive unit (not shown) and a rotating shaft 144. The drive unit drives the rubber ring pickup module 14 to rotate around the rotating shaft 144. When the opening / closing part 141 is in the closed state, the drive unit drives the rubber ring pickup module 14 to rotate 90° around the rotating shaft 144 to pick up the rubber ring 2 from the rubber ring positioning seat 13. The drive unit employs a combination structure of a servo motor and a harmonic reducer, and is rotatably connected to the rotating shaft 144 via gears. Its output shaft is coaxially connected to the rotating shaft 144 to provide rotation angle control. When the opening / closing part 141 is in the closed state, the drive unit receives a command and drives the rubber ring pickup module 14 to rotate precisely 90° around the rotating shaft 144, causing the axis of the support needle 142 to change from horizontal to vertical downward, thereby penetrating the inner diameter of the rubber ring 2 located on the rubber ring positioning seat 13 to complete the pickup action. An angle limiting block is provided at the connection end between the rotating shaft 144 and the opening and closing part 141. When the rotation reaches the 90° position, the drive part 143 automatically stops and locks to prevent positioning deviation caused by over-rotation.

[0033] In some embodiments, please refer to Figures 8 to 9 The card tray positioning base 15 includes a card tray groove 151 for fixing the card tray 2. The card tray 3 includes a card tray rubber ring groove 31 and a card tray door plate 32. The card tray door plate 32 is located at the outer edge of the card tray rubber ring groove 31. The rubber ring 2, after being opened, passes through the card tray door plate 32 and is directly assembled into the card tray rubber ring groove 31. The card tray groove 151 is a contoured groove structure set on the card tray positioning base and matching the shape of the card tray 3. For example, it is a rectangular groove, an irregular groove, or a special groove with a positioning boss. Its size is slightly larger than the outer contour of the card tray 3 to ensure that the card tray 3 can be easily placed into the groove without being too tight and stuck. After the card tray 3 is placed into the card tray groove 151, it can be further fixed by mechanical limiting or elastic clamping parts to prevent the card tray 3 from shifting during the assembly of the rubber ring 2. The card tray rubber ring groove 31 is an annular groove located in the card tray 3. Its size is strictly matched with the outer diameter and cross-sectional shape of the rubber ring 2. It is used to fix the position of the rubber ring 2 after assembly and ensure its protective function. The card holder panel 32 is located on the outer edge of the card holder rubber ring groove 31. It is a vertical plate structure perpendicular to the surface of the card holder 3, used to protect the opening edge of the card holder rubber ring groove 31 and prevent the rubber ring 2 from being damaged by collision during assembly. At the same time, it serves as a guide structure when the rubber ring 2 is inserted, guiding the rubber ring 2 into the card holder rubber ring groove 31 in the correct direction. The rubber ring picking module 14 moves the rubber ring 2 to the side of the card holder 3. By horizontal translation, the expanded rubber ring 2 is brought close to the card holder panel 32. When the rubber ring 2 has completely passed through the card holder panel 32 and entered the card holder rubber ring groove 31, the support pin 142 gradually releases the expansion force on the rubber ring 2. The rubber ring 2 rebounds due to its own elasticity and fits tightly against the inner wall of the card holder rubber ring groove 31.

[0034] In some embodiments, the rubber ring installation device 1 includes a first guide rail 16 and a second guide rail 17. Both the first guide rail 16 and the second guide rail 17 are fixed to the control console 10 via a support frame 101. The first guide rail 16 and the second guide rail 17 are arranged parallel to each other. The rubber ring positioning seat 13 is slidably mounted on the first guide rail 16 and reciprocates along the direction of the first guide rail 16. The card tray positioning seat 15 is slidably mounted on the second guide rail 17 and reciprocates along the direction of the second guide rail 17. The rubber ring installation device 1 achieves independent and coordinated reciprocating motion of the rubber ring positioning seat 13 and the card tray positioning seat 15 through the parallel first guide rail 16 and the second guide rail 17. The first guide rail 16 controls the spatial position adjustment of the rubber ring 2, and the second guide rail 17 controls the positioning and docking of the card tray 3. The parallel design and drive control of the two guide rails ensure the alignment of the rubber ring 2 and the rubber ring groove 31 of the card tray.

[0035] In some embodiments, the rubber ring mounting device 1 further includes a lens inspection module 18, which is fixed to the control console 10 via a support rod. The lens inspection module 18 is used to detect the position of the rubber ring 2 after it has been assembled into the card holder rubber ring groove 31, to determine whether the rubber ring 2 is properly assembled or if there are any defects. Specifically, the lens inspection module 18 is connected to the support rod via a connecting plate and includes a CCD lens for acquiring clear images of the rubber ring 2 within the card holder rubber ring groove 31. Specifically, after the rubber ring 2 is assembled into the card holder rubber ring groove 31, the card holder positioning seat 15 moves on the second guide rail 17 and reaches the inspection station of the rubber ring 2 to acquire images. By detecting and analyzing whether the rubber ring 2 is fully embedded in the card holder rubber ring groove 31 and whether there are any defects such as offset, skewness, overlap, deformation, damage, or non-adhesion, the assembly quality of the rubber ring 2 is ensured to meet the process requirements. Products that pass automatic inspection are directly conveyed to the next module unit for automatic packaging, while products that fail automatic inspection are rejected and placed in a defective product collection box for manual review or disposal. The rubber ring installation equipment 1, through a lens inspection module, achieves automated inspection of assembly quality, significantly improving product reliability and production efficiency.

[0036] This utility model provides a rubber ring installation device. The mechanism replaces the traditional manual one-by-one operation or the intermittent operation mode of semi-automatic equipment with a collaborative design of vibratory feeder directional feeding, robotic arm precise picking and placing, rubber ring positioning seat buffer conveying, rubber ring picking module controllable picking and opening, and card tray positioning seat high-precision assembly. This realizes the automated assembly of rubber rings, thereby greatly improving the assembly accuracy and production efficiency of rubber rings and significantly reducing labor costs.

[0037] This significantly improves assembly accuracy and production efficiency, and substantially reduces labor costs.

[0038] In some embodiments, the rubber ring installation method of the rubber ring installation device 1 provided by this utility model includes the following steps: In this embodiment, the rubber ring 2 is loaded onto the vibratory feeder 11, and the vibratory feeder 11 transports the rubber ring 2 in an orderly manner according to a preset direction.

[0039] In some embodiments, the rubber rings 2 to be assembled are batched into the flexible vibration table 1111 of the planar flexible vibration disk 111. The rubber rings 2 are initially stacked randomly or placed in random orientations. The planar flexible vibration disk 111 is driven by the vibration drive component 1112 to generate high-frequency micro-amplitude vibration. Under the vibration, the rubber rings 2 gradually move towards the discharge end and are conveyed into the material receiving cavity 1113, thereby enabling the rubber rings 2 with symmetrical structure to achieve disordered to ordered motion adjustment under the action of vibration.

[0040] In some embodiments, the rubber rings 2 to be assembled are batched into a track-type directional vibratory feeder. An eccentric vibration source within a rigid vibration base generates directional vibration energy to drive the spiral upward track to vibrate. Vibration friction drives the rubber rings 2 to move gradually along the track and adjust their posture. At this time, the identification component detects the posture of the passing rubber rings 2. When an asymmetrical rubber ring 2 is detected and its posture does not meet preset requirements, a straightening device will orient it to the correct posture. After directional screening, the rubber rings 2 are output one by one along the outlet track of the vibratory feeder 11, oriented and orderly conveyed into the rigid screen.

[0041] In this embodiment, according to the preset coordinate parameters, the robotic arm 121 is driven to move to the material picking station of the vibratory plate 11. After the rubber ring 2 is picked up by the suction head 122, the robotic arm 121 is driven to rotate and move above the rubber ring positioning seat 13, and the rubber ring 2 is placed on the rubber ring positioning seat 13.

[0042] In some embodiments, the robotic arm 121 drives the adsorption head 122 to move to the material handling station at the discharge port of the vibratory feeder 11 based on preset coordinate parameters. The adsorption head 122 generates negative pressure adsorption force through vacuum adsorption. When the adsorption head 122 contacts the upper surface of the rubber ring 2, the negative pressure causes the inner wall of the rubber ring 2 to tightly adhere to the adsorption surface 1221, thereby stably gripping the rubber ring 2. After completing the material handling, the robotic arm 121 drives the adsorption head 122 to rotate and translate from the material handling station to directly above the rubber ring positioning seat 13 based on a preset motion trajectory. After the robotic arm 121 moves the adsorption head 122 above the rubber ring positioning groove 131 of the rubber ring positioning seat 13, the center of the adsorption head 122 and the rubber ring positioning groove 131 are aligned. Then, the vacuum adsorption is turned off, causing the rubber ring 2 to detach from the adsorption head 122 and fall into the rubber ring positioning groove 131. After the rubber ring 2 is placed, the robotic arm 121 drives the adsorption head 122 to return to the picking station or standby position along the original path or optimized path, ready to carry out the next round of rubber ring picking operation, ensuring the efficient cycle of the entire transfer process.

[0043] In this embodiment, after placing multiple rubber rings on the rubber ring positioning seat 13, the rubber ring positioning seat 13 is controlled to rotate and move, so as to transport the multiple rubber rings to the picking station of the rubber ring picking module 14. In some embodiments, the adsorption head 122 sequentially places the rubber rings 2, which are directionally conveyed by the vibratory plate 11, into the rubber ring positioning grooves 131 of the rubber ring positioning seat 13 according to the cyclic process of step S200. After any one or more rubber ring positioning grooves 131 on the rubber ring positioning seat 13 have been loaded with rubber rings 2, the rubber ring positioning seat 13 rotates and moves along the direction of the first guide rail 16, moving the rubber ring positioning seat 13 to the side of the rubber ring picking module 14, so that the rubber ring positioning grooves 131 that have carried rubber rings 2 are sequentially aligned with the picking position direction of the rubber ring picking module 14. At this time, the rubber rings 2 are in a ready-to-be-picked state, and the rubber ring picking module 14 can directly pick up the rubber rings 2 from the rubber ring positioning grooves 131. After all the rubber rings 2 in the rubber ring positioning groove 131 have been picked up, the rubber ring positioning seat 13 continues to rotate and / or translate, and then repeats steps S200-S300 to continue loading and conveying new rubber rings, forming a closed-loop efficient process of loading-positioning-transfer.

[0044] In this embodiment, when the control opening and closing part 141 is in the closed state, the support pin 142 is inserted into the inner diameter of the rubber ring located at the picking station. After multiple rubber rings are picked up synchronously, the control opening and closing part 141 is in the open state, which drives the support pin 142 to expand radially to stretch the rubber ring to a preset size.

[0045] In some embodiments, the opening and closing portion 141 of the rubber ring pickup module 14 is in a naturally retracted state under the action of the driving unit, the elastic clamping arms 1411 move closer to each other, and the four support pins 142 are tightly gathered with the top of the elastic clamping arms 1411, forming a small radial dimension. At this time, the rubber ring pickup module 14 moves to the pickup station described in step S300, so that the retracted support pins 142 are aligned with the inner diameter of the rubber ring 2 already positioned in the rubber ring positioning groove 131 of the rubber ring positioning seat 13. The driving unit drives the rubber ring pickup module 14 to rotate 90° around the rotation axis 144, and the four support pins 142 simultaneously penetrate the inner diameter of the rubber ring 2 from four directions, picking up the rubber ring 2 from the rubber ring positioning groove 131. After the support pin 142 picks up the rubber ring 2, the drive unit drives the opening and closing part 141 to open outward, and the elastic clamping arms 1411 move away from each other. Since the support pin 142 is fixed to the top of the clamping arm 1411, the opening action of the elastic clamping arm 1411 directly drives the four support pins 142 to expand outward synchronously, so that the rubber ring 2 is stretched to the preset size. While the rubber ring 2 remains in the stretched state, the rubber ring picking module 14 carries the stretched rubber ring 2, rotates and moves to the next station, ready to perform the assembly of the rubber ring and the card holder.

[0046] In this embodiment, the rubber ring 2 is rotated and moved to the outside of the card tray door panel 32 by the rubber ring pickup module 14, so that the rubber ring 2 passes through the card tray door panel 32. Then, the opening and closing part 141 is controlled to contract so that the rubber ring 2 is disengaged from the support pin 142 and the rubber ring 2 is assembled into the card tray rubber ring groove 31.

[0047] In some embodiments, after the rubber ring 2 is opened and fixed in step S400, the rubber ring pickup module 14 is driven to move to the outside of the card tray door panel 32, so that the central axis of the opened rubber ring 2 is aligned with the central axis of the card tray rubber ring groove 31. The rubber ring pickup module 14 is slowly pushed forward in the horizontal direction, so that the opened rubber ring 2 gradually approaches and passes through the card tray door panel 32. During insertion, the support pin 142 maintains a radially expanded state, ensuring that the inner diameter of the rubber ring 2 continues to expand and adhere to the outer surface of the support pin 142, preventing the rubber ring 2 from shrinking and falling off. When the rubber ring 2 is partially embedded in the rubber ring groove 31, the driving part of the rubber ring pickup module 14 drives the opening and closing part 141 to contract inward, thereby causing the support pin 142 to contract. The radial retraction of the support pin 142 causes the rubber ring 2, which is in an expanded state, to lose its radial expansion force. Due to the contraction, the rubber ring 2 detaches from the surface of the support pin 142 and is completely fitted into the rubber ring groove 31 of the card holder, realizing the assembly of the rubber ring 2 and the card holder 3. After the rubber ring 2 detaches from the support pin 142 and is assembled into the rubber ring groove 31, a clear image of the rubber ring 2 in the card holder rubber ring groove 31 is captured by the CCD lens in the lens detection module, and the system detects and analyzes whether the rubber ring 2 is completely embedded in the card holder rubber ring groove 31, and whether there are any defects such as offset, skew, overlap, deformation, damage, or non-adhesion, thereby ensuring that the assembly quality of the rubber ring 2 meets the process requirements. Products that pass the automatic inspection are directly conveyed to the next module unit for automatic packaging. Products that fail the automatic inspection are rejected and sent to the defective product collection box for manual re-judgment or scrapping, thereby ensuring the assembly accuracy, consistency and yield of the rubber ring 2 and the card tray 3.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
