[0033] The following will be used in conjunction with the examples to describe in detail the implementation of this embodiment, and the technical solutions in this embodiment will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of this embodiment, not all of the embodiments. The components of the embodiment generally described and shown here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment provided in the accompanying drawings is not intended to limit the scope of the embodiment claimed for protection, but merely represents a selected embodiment of this embodiment. Based on the embodiments of this embodiment, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this embodiment.

[0034] like Figure 1 As shown, it is the USB structure, where the reference Figure 2 and Figure 3 , is the pin 104 structure to be bent in the embodiment, Figure 2 This is the state before bending. Figure 3 The embodiment provides a bending mechanism 20 for a USB assembly device to bend the pins 104 of the female connector 102. Before bending, the pins 104 are in a horizontal state, i.e., a straight plate structure, and the positions of adjacent pins 104 are staggered and distributed front to back. This embodiment is described for a USB with 8 pins 104, where the starting ends of 4 pins 104 are flush, and the starting ends of the other 4 pins 104 are also flush. However, most existing bending mechanisms 20 are performed manually or assembled by automated equipment after bending. Manual bending is costly, and assembly after bending places high demands on automated equipment, which is not conducive to more efficient and quick assembly. Based on the above situation, the structure of the bending mechanism 20 in this embodiment is as follows: refer to Figures 4-7, the bending mechanism 20 comprises fixed frames 201, first bending assemblies 202, second bending assemblies 203 and positioning assemblies 204 are arranged between the fixed frames 201, the first bending assembly 202 comprises a first bending cylinder 2021, a plate 2022 is connected to the output end of the first bending cylinder 2021, a first bending block 2023 is connected to the plate 2022, the output end of the second bending cylinder 2031 is connected with a guide block 2032, an inclined guide groove 20321 is formed in the guide block 2032, a connecting shaft 2033 is arranged in the inclined guide groove 20321 for connecting a moving block 2034, a second bending block 2035 is arranged on the outer side of the moving block 2034, the positioning assembly 204 comprises a positioning cylinder 2041, a pressing block 2042 is connected to the output end of the positioning cylinder 2041, when bending, the second bending block 2035 moves to above the needle foot 104 in a horizontal state, then the second bending block 2035 is driven to move in the bending direction, the first bending block 2023 and the second bending block 2035 are staggered to realize the bending of the needle foot 104 in the same direction, and the realization means is as follows: A plurality of first protruding blocks 20231 are formed on the front end face of the first bending block 2023, first gaps 20232 are formed between the first protruding blocks 20231, a plurality of second protruding blocks 20351 are formed on the front end face of the second bending block 2035, second gaps 20352 are formed between the second protruding blocks 20351, the first protruding blocks 20231 and the second protruding blocks 20351 are distributed in a staggered manner, the first bending block 2023 and the second bending block 2035 move towards each other, and the action principle is as follows: First, the positioning cylinder 2041 drives the pressing block 2042 to press the USB in the fixture, and the pin 104 is exposed outside the fixture. Then the second bending cylinder 2031 is actuated to move the second bending block 2035 toward the pin 104. Due to the presence of the second protruding block 20351 and the second notch 20352, the second protruding block 20351 will press on the corresponding pin 104. Then the first bending cylinder 2021 is driven to move the first bending block 2023 toward the pin 104. The first protruding block 20231 will bend the corresponding pin 104, and the pin 104 corresponding to the first protruding block 20231 will bend in the second notch 20352. The pin 104 corresponding to the second protruding block 20351 will bend within the first notch 20232, but the second bending block 2035, where the second protruding block 20351 is located, will not move. The first bending block 2023 moves in the direction in which the pin 104 needs to be bent. Therefore, under the combined action of the second protruding block 20351 and the first notch 20232, the bending direction of the corresponding pin 104 will be consistent with the movement direction of the first bending block 2023. This ensures that all pins 104 can be bent in the same direction in just one operation, which is more efficient and can achieve automated production. In addition, there is no mechanical interference between the two sets of bending blocks during movement. The first notch 20232 provides a movement channel for the second protruding block 20351, and the second notch 20352 provides a movement channel for the first protruding block 20231, allowing the two sets of bending actions to simultaneously act on different bending positions of the pin 104 of the same female connector 102. The bidirectional forces generated by the opposite movements keep the pins 104 in a balanced force during the bending process, thereby preventing the pins 104 from being deflected or twisted due to unilateral force.

[0035] Example 1

[0036] like Figures 4-16 As shown, this embodiment is a USB assembly device for assembling Figure 1As shown in the USB connector 10, the connector is composed of a male head 101, a female head 102, and a fastener 103 for connecting the male head 101 and the female head 102. In addition to the bending mechanism 20 in Embodiment 1, the USB assembly device provided in the embodiment further includes a male head 101 feeding mechanism, a male head 101 grabbing mechanism, a male head 101 positioning mechanism, a female head 102 feeding mechanism, a female head 102 pushing mechanism, a fastener 103 feeding mechanism, a fastener 103 pushing mechanism, a pressing mechanism 100, a dividing disc 110, and a rack 120. The dividing disc 110 is distributed with a plurality of clamps in the circumferential direction for placing the male head 101 or the assembled part in different processes. The rack 120 carries each mechanism, and the male head 101 grabbing mechanism, the male head 101 positioning mechanism, the female head 102 pushing mechanism, the fastener 103 pushing mechanism, the bending mechanism 20, and the pressing mechanism 100 are distributed in the circumferential direction of the dividing disc 110. The male head 101 feeding mechanism transports the male head 101 to the grabbing mechanism, the male head 101 grabbing mechanism transfers the male head 101 to the clamp, and the male head 101 positioning mechanism adjusts the position of the male head 101 for the female head 102 installation. The female head 102 feeding mechanism transports the female head 102 to the pushing mechanism, and the female head 102 pushing mechanism completes the assembly of the female head 102 and the male head 101. The fastener 103 feeding mechanism transports the fastener 103 to the pushing mechanism, and the fastener 103 pushing mechanism pushes the fastener 103 to the assembly position. The bending mechanism 20 processes the female head 102 pin, and the pressing mechanism 100 presses the assembly.

[0037] The dividing disc 110 refers to a disc type conveying device with a rotary drive assembly, which can specifically adopt a rotary table structure driven by a servo motor, and realizes process integration through the circumferential arrangement of the clamp. The rack 120 refers to a frame structure carrying each functional module, which can specifically adopt a three-dimensional support platform built by aluminum alloy profiles, and reduces the material transfer path through space layout optimization. The male head 101 positioning mechanism refers to an execution device with position correction function, which can specifically adopt a wedge-shaped positioning block combination driven by a cylinder, and ensures the assembly precision of the female head 102 through the adjustment of the foot spacing. The female head 102 pushing mechanism refers to an assembly device with lifting and pushing composite action, and the fastener 103 pushing mechanism refers to a micro part assembly device with multi-station cooperation, which can specifically adopt a top pushing structure with three cylinder linkage, and completes the installation of the fastener 103 through the cooperation of the alignment of the installation groove and the pushing of the guide rod 9018.

[0038] Specifically, the index plate 110 is intermittently rotated under the drive of a servo motor, so that the clamp sequentially passes through each station. The male head 101 is transported to the grabbing position by a vibration plate through a track, a three-axis mechanical arm grabs the male head 101 and places it in the clamp. The cylinder of the positioning mechanism drives the wedge-shaped block to press down, and the spacing between the feet of the male head 101 is expanded to a set value through the sawtooth structure. The female head 102 is transported to the lifting ejector rod 705 by another vibration plate, the ejector rod 705 lifts the female head 102 to a pushing height, and then a horizontal cylinder pushes the female head 102 into the gap between the feet of the male head 101 to complete the assembly. When the index plate 110 rotates to the bending station, the bending block bends the pins of the female head 102 into a shape. The fastener 103 is transported to the slot 5051 of the transverse plate 905 through the track, the first cylinder 902 drives the rotating top block 906 to position the fastener 103, the second cylinder 903 drives the moving plate 9014 to align the installation slot, and the third cylinder 904 pushes the fastener 103 into the assembly body through the guide rod 9018. Finally, the compression mechanism 100 applies vertical pressure to the whole assembly to ensure its stability.

[0039] Compared with the prior art, the traditional USB assembly needs to be completed in separate stations, i.e., the positioning of the male head 101, the assembly of the female head 102, the bending of the pins, and the installation of the fastener 103. The workpiece needs to be transferred and positioned multiple times. In the prior art, the assembly of the female head 102 relies on manual adjustment of the spacing between the feet. In the present scheme, the posture of the male head 101 is automatically corrected by the wedge-shaped positioning block, ensuring the consistency of the assembly. The traditional installation of the fastener 103 uses a single push rod structure, which is prone to deviation. In the present scheme, the installation precision of the micro parts is improved by the composite guide design of the installation slot and the guide rod 9018.

[0040] Through the above technical scheme, the present embodiment realizes the continuous production of the USB assembly process, completes all assembly steps within the rotation period of the index plate 110, actively corrects the feet of the male head 101 by the positioning mechanism to improve the success rate of the assembly of the female head 102, and cooperatively designs the three stations of the fastener 103 pushing mechanism to improve the installation efficiency of the micro parts.

[0041] The present embodiment further proposes that the male head 101 feeding mechanism, the female head 102 feeding mechanism, and the fastener 103 feeding mechanism are all vibration plates.

[0042] The vibration plate is an automatic feeding device that sorts materials in a predetermined posture through vibration. It can be realized by combining a high-frequency vibration component driven by an electromagnetic drive with a spiral track. The movement speed and direction of the materials can be controlled by adjusting the vibration frequency and the track inclination. Its role is to automatically arrange the scattered parts into a predetermined posture and continuously convey them to the assembly station, avoiding the efficiency loss caused by manual intervention.

[0043] The vibration disc in the male head 101 feeding mechanism designs a track for the structural characteristics of the male head 101 shell. Specifically, a stepped track can be used in cooperation with a limiting baffle to achieve this. The movement path of the male head 101 shell is constrained by the track width and limiting height, ensuring that it enters the grabbing station in a fixed direction. This solves the problem of positioning deviation caused by the irregular shape of the male head 101 shell.

[0044] The vibration disc in the female head 102 feeding mechanism designs a track for the arrangement accuracy requirements of the female head 102 pins. Specifically, a multi-stage screening track can be used in cooperation with a guide plate to achieve this. The pins are arranged at a predetermined interval by the guide plate, and the vibration frequency is adjusted to control the delivery interval of the pins. This avoids bending or misalignment of the pins due to dense stacking.

[0045] The vibration disc in the fastener 103 feeding mechanism designs a track for the thin-walled structure of the fastener 103. Specifically, a buffer track can be used in cooperation with a flexible guide to achieve this. By reducing the vibration intensity and increasing the friction coefficient of the track surface, the collision and deformation of the fastener 103 during transportation are reduced. This prevents surface damage or deformation of the fastener 103 due to rigid contact.

[0046] The male head 101 grabbing mechanism is provided at the discharge port of the male head 101 feeding mechanism. The male head 101 grabbing mechanism includes a three-axis moving assembly 401 and a male head 101 grabbing air claw provided on the three-axis moving assembly 401. The three-axis moving assembly 401 drives the male head 101 grabbing air claw to move in three-axis directions, and grabs the male head 101 from the discharge port of the male head 101 feeding mechanism to the corresponding clamp.

[0047] The three-axis moving assembly 401 refers to a mechanical transmission device that can perform linear displacement in the X-axis, Y-axis, and Z-axis three orthogonal directions. In this embodiment, a pneumatic cylinder is used to provide multiple degrees of freedom positioning capability for the male head 101 grabbing air claw. The male head 101 grabbing air claw refers to an execution element that uses compressed air to drive the clamping jaw to open and close. Specifically, a parallel air claw or a rotary air claw can be used to achieve this. The flexible clamping surface contacts the non-functional area of the male head 101, avoiding mechanical damage to the male head 101 conductive terminal by clamping force.

[0048] Specifically, the spatial coordinate deviation between the discharge port of the male head 101 feeding mechanism and the index plate 110 clamp is eliminated by the coordinate compensation function of the three-axis moving assembly 401. The male head 101 grabbing air claw completes the lateral span adjustment in the X-axis direction, realizes the longitudinal feed positioning in the Y-axis direction, and performs the vertical lifting action in the Z-axis direction. When the male head 101 reaches the predetermined position of the discharge port, the air claw clamps the notch of the flat area on both sides of the male head 101, which is a self-structure of the male head 101. The three-axis moving assembly 401 moves the male head 101 to the position directly above the index plate 110 clamp according to the preset path, and the Z-axis is lowered to accurately embed the male head 101 into the clamp positioning groove. The whole process is monitored by the closed-loop control system to ensure that the posture of the male head 101 is strictly aligned with the clamp notch 5051.

[0049] Compared with the prior art, the traditional male head 101 grabbing mechanism is mostly composed of a single-axis mechanical arm and a vacuum suction nozzle to complete the transfer. However, there are problems such as insufficient planar positioning accuracy and inability to actively adjust in the vertical direction, which leads to collision or tilting of the male head 101 with the clamp notch 5051. Some improved solutions use a two-axis mechanical hand to cooperate with a rotary chuck, which can realize angle correction, but the lack of movement freedom leads to complex grabbing path planning, prolonging the production cycle.

[0050] Through the above technical solutions, the embodiment realizes the cooperative control of three-dimensional space accurate positioning and flexible clamping during the grabbing process of the male head 101, eliminates the cumulative positioning error in the material transfer path, avoids mechanical damage to the surface plating layer of the male head 101 during the grabbing process, and significantly improves the grabbing efficiency by shortening the transfer distance and simplifying the motion trajectory.

[0051] The embodiment further proposes a male head 101 positioning mechanism, which includes a mounting vertical plate 501, a cylinder mounting plate one 502, a cylinder 503, and a connecting block 504 connected with the output end of the cylinder. The connecting block 504 is further connected with a first positioning block 505 and a second positioning block 506. The mounting vertical plate 501 is fixed on the rack 120. The first positioning block 505 acts on the upper end face of the male head 101 for pressing the male head 101. The second positioning block 506 is used to determine the distance between the two legs of the male head 101. The lower end of the first positioning block 505 forms a notch 5051 matched with the shape of the male head 101. The lower end of the second positioning block 506 forms a wedge-shaped sawtooth 5061, and the wedge-shaped sawtooth 5061 forms a support block 5062. When the cylinder is pressed down, the support block 5062 enters the space between the legs and makes the distance between the legs meet the requirement of the female head 102 insertion.

[0052] The mounting vertical plate 501 is a basic support structure for bearing the cylinder mounting plate one 502, which can be fixed on the surface of the rack 120 by bolts to establish a stable positioning reference surface. The cylinder mounting plate one 502 is a fixed plate for mounting the cylinder, which can be connected perpendicularly to the mounting vertical plate 501 to ensure that the movement track of the output end of the cylinder is perpendicular to the fixture plane. The first positioning block 505 is a pressing component with a notch 5051, which can be a hard alloy block processed by wire cutting to match the groove on the upper end surface of the male head 101, and the male head 101 is pressed by the contact surface to prevent axial displacement. The second positioning block 506 is a foot spacing adjusting component with a wedge-shaped sawtooth 5061, which can be a tool steel milled into a sawtooth structure after heat treatment, and the angle of the sawtooth inclined surface can be set to 30-45 degrees, and the spacing is expanded by the inclined surface contacting the inner wall of the foot. The support block 5062 is a protruding structure between the wedge-shaped sawtooth 5061, which can be formed into a trapezoidal cross-section boss by milling, and is embedded in the foot gap to implement mechanical expansion when the cylinder is pressed down.

[0053] Specifically, the cylinder drive connecting block 504 drives the first positioning block 505 and the second positioning block 506 to press down synchronously. The notch 5051 of the first positioning block 505 completely matches the upper end surface of the male head 101, and the axial deviation of the male head 101 in the fixture is eliminated by vertical pressure. When the wedge-shaped sawtooth 5061 of the second positioning block 506 contacts the inner wall of the foot, the inclined surface guides the support block 5062 to gradually insert into the foot gap, and as the cylinder stroke advances, the trapezoidal cross-section of the support block 5062 forces the foot to expand outward. When the cylinder reaches the lower dead point, the foot spacing is accurately adjusted to the insertion tolerance range of the pin of the female head 102. This process simultaneously completes the pressing positioning of the male head 101 and the adjustment of the foot spacing in a single cylinder action, avoiding the cumulative error caused by step-by-step operation.

[0054] Compared with the prior art, the traditional foot spacing adjustment needs to be manually corrected after measuring with a protractor, which has the problems of low efficiency and poor consistency. The existing mechanical expansion device mostly uses independent drive mechanisms to control the pressing and expansion actions respectively, resulting in complex device structure and difficult synchronization of action timing. The present scheme integrates the pressing and expansion functions in a single linear motion through a single cylinder drive composite positioning structure, which simplifies the mechanical structure and eliminates the timing control error.

[0055] Through the above technical scheme, the present embodiment effectively solves the problem that the male head 101 fails to be assembled with the female head 102 due to positioning deviation in the fixture. The mechanical foot spacing adjustment structure ensures that the foot spacing accurately matches the pin size of the female head 102, avoiding pin bending or poor contact. The composite positioning structure automatically corrects the foot spacing while pressing the male head 101, improving the yield and production rhythm of USB assembly.

[0056] The embodiment further provides that the female head 102 pushing mechanism is arranged at the end of the female head 102 feeding mechanism, and comprises a vertically arranged fixed mounting plate 701, an upper plate 702 arranged perpendicularly to the fixed mounting plate 701, a lifting cylinder 703 arranged at the side of the fixed mounting plate, and a female head 102 pushing cylinder arranged on the upper plate 702, wherein the output end of the lifting cylinder 703 is connected with a top rod 705, the top rod 705 is used for receiving the female head 102 and driving the female head 102 to lift so as to push the female head 102 into the male head 101 by the female head 102 pushing cylinder.

[0057] The fixed mounting plate 701 refers to a support structure perpendicular to the horizontal plane, which can be a metal plate fixed on the rack 120 by bolts to provide a rigid mounting base for the lifting cylinder 703, so as to avoid positional deviation caused by mechanism vibration during pushing.

[0058] The upper plate 702 refers to a planar member connected at a right angle to the fixed mounting plate 701, which is used for bearing the female head 102 pushing cylinder and forming a spatial layout, so that the lifting cylinder 703 and the female head 102 pushing cylinder are arranged in different planes to reduce motion interference.

[0059] The lifting cylinder 703 refers to a vertically driven pneumatic actuator, which can be a thin cylinder with a guide rod, and is used for receiving the female head 102 fed by the female head 102 feeding mechanism and adjusting the height of the female head 102 to match the assembly position of the male head 101, so as to eliminate assembly misalignment caused by height difference.

[0060] The female head 102 pushing cylinder refers to a horizontally driven pneumatic actuator, which is used for executing horizontal pushing after the lifting action of the top rod 705 is completed, so as to push the female head 102 into the male head 101 along a straight path to ensure the straightness of the pushing track.

[0061] The top rod 705 refers to a rod-shaped part connected with the output end of the lifting cylinder 703, which can be a stainless steel cylindrical rod, and is used for realizing vertical position adjustment of the female head 102 through lifting motion.

[0062] Specifically, after the female head 102 feeding mechanism feeds the female head 102 to the clamping position of the top rod 705, the lifting cylinder 703 drives the top rod 705 to vertically ascend or descend, so that the height of the female head 102 is aligned with the assembly position of the male head 101 in the clamp. After the height adjustment is completed, the female head 102 pushing cylinder is started to push the female head 102 into the corresponding slot of the male head 101 along a horizontal straight line. The right-angle layout of the fixed mounting plate 701 and the upper plate 702 forms a spatial orthogonal relationship between the motion directions of the lifting cylinder 703 and the female head 102 pushing cylinder, so as to avoid mechanical interference when the two cylinders act. The vertical motion of the top rod 705 and the horizontal motion of the female head 102 pushing cylinder are executed step by step, which simplifies the control timing and reduces the positioning error of multi-axis linkage.

[0063] Compared with the prior art, the traditional female head 102 pushing mechanism often uses a single cylinder oblique pushing, which is easy to cause the female head 102 and the male head 101 to be misaligned due to the deviation of the movement track, and the height adjustment needs to rely on an additional positioning mechanism. The scheme decomposes the height adjustment and the horizontal pushing into independent procedures through the coordinated step-by-step action of the lifting cylinder 703 and the female head 102 cylinder, uses the rigid support of the fixed mounting plate 701 and the vertical guidance of the top rod 705 to ensure the position accuracy of the female head 102 in the vertical direction, and avoids the pushing path deviation through the horizontal linear motion of the female head 102 cylinder. The structure design of the right-angle layout reduces the space occupation of the equipment, so that the female head 102 pushing mechanism can be directly integrated at the end of the feeding mechanism, and the material transfer distance is shortened.

[0064] Through the above technical scheme, the embodiment realizes the time sequence separation of the height accurate adjustment of the female head 102 in the vertical direction and the linear pushing in the horizontal direction, solves the assembly failure problem caused by the height misalignment or the deviation of the pushing track. The step-by-step control of the lifting cylinder 703 and the female head 102 cylinder simplifies the movement logic and improves the assembly beat stability. The right-angle structure design of the fixed mounting plate 701 and the upper plate 702 reduces the mechanism complexity, makes the female head 102 pushing action seamlessly connect with the feeding process, and reduces the waiting time between procedures.

[0065] The embodiment further proposes that the buckle 103 pushing mechanism is arranged at the discharge port of the buckle 103 feeding mechanism, comprising a mounting bracket 901, a first cylinder 902, a second cylinder 903, and a third cylinder 904. The mounting bracket 901 is connected with a feeding track 130, which serves as a moving track for the buckle 103. A transverse plate 905 is arranged at the discharge port of the feeding track 130. A notch 5051 is formed in the transverse plate 905. A rotating top block 906 for abutting against the buckle 103 is arranged in the transverse notch 90515051. A containing plate 907 is arranged at one side of the rotating top block 906. A containing groove 908 for the action of the rotating top block 906 is formed in the containing plate 907. A driving rod 9010 is arranged at the bottom of the rotating top block 906. The driving rod 9010 is connected with a driving block 9011. The driving block 9011 is connected with a linkage block 9012. The linkage block 9012 is connected with the output end of the first cylinder 902. The first cylinder 902 is arranged at the bottom of the mounting bracket 901. The transverse plate 905 is connected with a positioning plate 9013. A moving space is formed between the transverse plate 905 and the positioning plate 9013. A moving plate 9014 is arranged in the moving space. A first accommodating groove 9015 matching the shape of the buckle 103 is arranged at the head of the moving plate 9014. The end of the moving plate 9014 is connected with the output end of the second cylinder 903. The end of the positioning plate 9013 is formed with a second accommodating groove 9016 matching the shape of the head of the moving plate 9014. A through groove 9017 is formed in the inner side of the second accommodating groove 9016. The third cylinder 904 is arranged at the outer side of the feeding track 130. The output end of the third cylinder 904 is connected with a guide rod 9018. The second cylinder 903 drives the moving plate 9014 to move towards the second accommodating groove 9016, so that the first accommodating groove 9015 and the second accommodating groove 9016 are aligned, thereby driving the guide rod 9018 to move towards the through groove 9017, so that the buckle 103 is sequentially separated from the first accommodating groove 9015 and the second accommodating groove 9016.

[0066] Among them, the rotating top block 906 refers to a component that applies dynamic clamping force to the buckle 103 through rotating action. Specifically, it can be realized by a metal block with an inclined surface. The bottom is connected with the cylinder through the driving rod 9010. When rotating in the notch 5051, it can limit the lateral displacement of the buckle 103.

[0067] Among them, the first accommodating groove 9015 and the second accommodating groove 9016 refer to positioning structures matching the shape of the buckle 103. Specifically, they can be realized by grooves formed by numerical control machining. After alignment, they form a continuous positioning channel, which ensures that the buckle 103 maintains a stable posture during movement.

[0068] Among them, the guide rod 9018 refers to a linear motion component for pushing the buckle 103 away from the positioning structure. Specifically, it can be realized by a metal rod with chrome plating on the surface, which can accurately push the buckle 103 to the assembly position.

[0069] Specifically, when the fastener 103 enters the notch 5051 area of the transverse plate 905 from the feed rail 130, the first cylinder 902 drives the linkage block 9012 to drive the driving block 9011 downward, so that the rotating top block 906 rotates and clamps the fastener 103. When the second cylinder 903 pushes the moving plate 9014 to move towards the positioning plate 9013, the installation groove one 9015 is aligned with the installation groove two 9016 to form a continuous channel, the rotating top block 906 is reset to release the fastener 103, and the fastener 103 falls into the installation groove one 9015. The third cylinder 904 then drives the guide rod 9018 to pass through the through slot 9017, pushes the fastener 103 from the installation groove one 9015 into the installation groove two 9016, and finally enters the assembly position. The whole process realizes the staged positioning and pushing of the fastener 103 through the time sequence control of the three cylinders, avoiding deviation or jam caused by single pushing.

[0070] Compared with the prior art, the traditional fastener 103 installation relies on a single cylinder for direct pushing, which is easy to cause the fastener 103 to fall off due to inertia or vibration, and lacks an intermediate positioning link, which is easy to cause jam. The scheme forms a multi-stage cooperative control through the dynamic clamping of the rotating top block 906, the continuous positioning of the installation groove, and the accurate pushing of the guide rod 9018, which reduces the number of transfers while improving the positioning accuracy.

[0071] Through the above technical scheme, the embodiment realizes the whole-process continuous positioning and pushing of the fastener 103 from the feeding to the assembly position, solves the problem of low efficiency caused by multiple transfers in the traditional process, and effectively prevents the fastener 103 from deviating or falling off during the pushing process through the mechanical limiting structure, which significantly improves the assembly accuracy and yield.

[0072] The embodiment further proposes a material collecting mechanism 140, which includes a material collecting grabbing mechanism 1401 and a material box 1402. The material collecting grabbing mechanism 1401 is identical in structure to the male head 101 grabbing mechanism and is used to grab the assembled USB in the fixture on the indexing disc 110.

[0073] The material collecting grabbing mechanism 1401 is an automatic grabbing device with a three-axis moving assembly 401 and a pneumatic gripper, which can be implemented by combining a linear module driven by a servo motor and a pneumatic gripper. By reusing the structure design of the male head 101 grabbing mechanism, the positioning accuracy and motion trajectory consistency of the grabbing action are ensured. The material box 1402 is a container for storing finished products, which can be a multi-layer separated metal box structure and can be quickly replaced after full loading through a slide rail mechanism.

[0074] Specifically, when the assembled USB is carried by the fixture on the index plate 110 to the material receiving station, the three-axis moving assembly 401 drives the pneumatic claw to move above the fixture, and after the pneumatic claw clamps the finished product, the pneumatic claw moves along a predetermined path to release above the material box 1402. Since the material receiving grabbing mechanism 1401 and the male head 101 grabbing mechanism adopt the same structure, the motion parameters and positioning reference have been calibrated in the equipment debugging stage, avoiding the calibration time loss caused by the addition of the mechanism. The material box 1402 detects the loading state through the photoelectric sensor, and triggers a prompt signal when reaching the preset capacity.

[0075] Compared with the prior art, the finished product collection in the traditional process needs to be manually operated or completed by configuring an independent mechanical arm, which increases the equipment area and requires an additional debugging period. The scheme reuses the structure of the existing grabbing mechanism, realizes seamless connection of the finished product transfer process while maintaining the compact layout of the production line, and eliminates the beat delay caused by the cooperation of multiple devices.

[0076] Through the above technical scheme, the embodiment realizes automatic transfer and centralized storage of the assembled USB finished product, and solves the efficiency loss problem caused by manual taking and placing or independent material receiving equipment in the traditional process. Through the structural design of the grabbing mechanism, the types of equipment components and maintenance costs are reduced, and the continuity of the production process is ensured by using the automatic material box 1402 management.
