Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency connector production, and in particular to a radio frequency connector production fixture and a working method thereof. Background Art

[0002] RF connectors are used to transmit RF signals with a wide transmission frequency range, which can reach 18 GHz or higher. They are mainly used in radar, communication, data transmission and aerospace equipment. RF connectors usually need to go through multiple processes such as turning, welding, crimping and testing, and each process has high requirements on the positioning accuracy and clamping stability of connector components.

[0003] After searching, the invention patent with publication number CN114336223A discloses a RF connector production and fixing device and its working method. The female head is inserted into the storage slot, and the male head is inserted into the card slot at the same time. The elastic pad clamps and fixes the male head. The male head is flipped and the opening is downward and inserted into the interior of the female head corresponding to the female head. The RF connector is assembled without manual assembly, which speeds up the production.

[0004] In the traditional cable docking method, the connection between the installation head (such as male head and female head) and the cable end often requires manual alignment and operation, which leads to problems such as inaccurate positioning, large angle error, and inadequate insertion. In addition, the manual operation efficiency is low, which is not conducive to mass production. The connection process lacks a stable positioning and limiting mechanism, especially during the vertical insertion, flipping or corner transition of the installation head, which may cause axial looseness, joint warping and other problems, affecting the connection quality. Summary of the invention

[0005] The object of the present invention is to provide a radio frequency connector production fixture and a working method thereof to solve the problems mentioned in the above background technology.

[0006] The technical problems mainly solved by the present invention are: The connection between the installation head (such as male head and female head) and the cable end often requires manual alignment and operation, which may cause problems such as inaccurate alignment, large angle error, and incomplete insertion. In addition, the manual operation efficiency is low, which is not conducive to mass production. There is a lack of stable positioning and limiting mechanisms during the plug-in process, especially during the vertical insertion, flipping or corner transition of the installation head, which may cause problems such as axial looseness and joint warping, affecting the connection quality.

The upper surface of the adjusting seat is provided with a plurality of unwinding rollers. One end of the cable passes out from one side of the bottom of the unwinding roller, and the other end of the cable passes out from the other side of the top of the unwinding roller. On the top of the inner cavity of the processing chamber, two transmission screws are respectively sleeved with sliding seats. The bottom surface of each sliding seat is connected with an electric gripper one that clamps the end of the corresponding cable through an electric push rod one. On the upper surface of each assembly chamber, a conveying frame is installed. Inside the conveying frame, a clamping and pushing unit for positioning the mounting head is lifted and lowered. The clamping and pushing unit includes a plurality of notches provided on the inner wall surface of the conveying frame. At the top of one end of the conveying frame, there is a lifting plate pushed by a segmented stroke cylinder twice. The bottom surface of the lifting plate is installed with an electric gripper two that clamps the mounting head at a fixed point. One clamping block of the electric gripper two is hidden in the corresponding notch. Inside the assembly chamber, there is a locking unit for docking the mounting head and the cable. The locking unit includes rotating plates rotatably installed on the inner walls on both sides of the assembly chamber. On the inner wall surface of each rotating plate, a vertical guide rail is installed vertically. The two vertical guide rails move synchronously. The slider connected to the outside of the vertical guide rail is connected with a limiting seat. At the bottom of the inner cavity of the limiting seat, a pushing member for clamping the mounting head is installed. The top of the limiting seat is open, and a blocking ring is provided at the bottom of the limiting seat.

[0008] A further technical improvement of the present invention is that the pushing member includes an airbag provided in the middle of the inner cavity of the limiting seat. A clamping plate is provided on the outside of the airbag, and elastic pads are provided at both ends of the airbag. The end of the elastic pad is fixed to the inner wall of the limiting seat.

[0009] A further technical improvement of the present invention is that a pressing plate for limiting the end of the mounting head is provided in the upper part of the inner cavity of the limiting seat. An electromagnet is installed in the mounting seat outside the limiting seat. A rod body connected through an armature in the electromagnet is fixed to the outside of the pressing plate.

[0010] A further technical improvement of the present invention is that several conveying grooves for positioning and conveying the mounting head are provided inside the conveying frame. At the bottom surface of the end of each conveying groove, a feeding port is provided. A blocking plate is rotatably installed at the end of the inner cavity of the feeding port through a rotating motor. A through cavity communicating with the feeding port is provided on the upper surface of the assembly chamber. A storage cavity for the blocking plate to rotate into is provided at the edge of the through cavity.

[0011] A further technical improvement of the present invention is that openings are provided on both sides of the processing chamber, and two groups of co-linear slide rails are installed on the base platform. The two lifting stations slide on the corresponding slide rails respectively. The lifting station also includes a slide table sliding on the slide rail, and two groups of synchronously moving stroke cylinders are installed on the top surface of the slide table, and the driving end of the stroke cylinder is fixed to the bottom surface of the adjustment seat.

[0012] A further technical improvement of the present invention is that the lifting station also includes a plurality of support bracket groups for carrying the unwinding rollers, the support bracket groups at both ends are threadedly connected to the bidirectional screw in the adjustment seat, and the middle support bracket group slides on the damping guide rail on the adjustment seat.

[0013] A further technical improvement of the present invention is that both sides of the top of the inner cavity of the processing chamber are connected by two electric push rods installed on the rotating disk, and the inner wall surface of the docking frame is equipped with a plug-in component that is snap-fitted with the end of the unwinding roller.

[0014] A further technical improvement of the present invention is that: a welding unit for hot-melt-compression-joining the mounting head and the cable end is provided on one side of the inner wall surface of the assembly chamber adjacent to the locking unit; The welding unit includes two connecting seats driven by a synchronous cylinder. The connecting seats are semi-annular structures. A heating welding plate is fitted on the inner wall surface of each connecting seat, and two guide plates are installed on the outer edge of each connecting seat. A limit rod that slides with the corresponding guide plate is installed on the inner wall surface of the assembly chamber.

[0015] A working method of a radio frequency connector production fixture, the working method comprising the following steps: Step 1: Multiple mounting heads are transported to the end position by the conveying slots in the conveying racks on both sides, and the electric clamp 2 is opened, and moves down along the slot with one push of the lifting plate to clamp the mounting heads at a fixed point; Step 2: After that, the blocking plate rotates and opens, and the lifting plate moves down for the second time. The limiting seat is driven by the vertical guide rail to the lower position of the through cavity. The mounting head enters the limiting seat and is restricted by the pressing plate on the end of the mounting head. The airbag expands to push the clamping plate to clamp the outer wall of the mounting head. Step 3: Next, the limit seat moves down to the initial height, and then the limit seat flips clockwise to align the plugging direction of the installation head with the end of the cable. At this time, the vertical guide rail becomes horizontal, and the limit seat slides horizontally close to the cable end, and the cable end slides toward the assembly chamber under the sliding of the slide seat, thereby completing the plugging of the two ends of the cable with the corresponding installation head; Step 4: Use the synchronous cylinder to push the two connection seats, drive the corresponding heating welding plate and the cable end of the plug-in installation head to press together, and complete the installation by hot melting; Step 5. The docking frames on both sides then release the restrictions on the lifting station. The lifting station descends in height and slides on one slide rail to leave the interior of the processing room. The lifting station on the other slide rail slides into the processing room until it is raised to the position of the docking frame and is used alternately for processing.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a clamping and pushing unit, a locking unit and a slidable electric clamp, the installation head is first clamped at a fixed point during the first movement; the second push makes the clamped installation head move down and enter the assembly chamber; when the limit seat slides close to the top of the assembly chamber, the installation head is accurately loaded into the limit seat from the open end, and the blocking ring blocks one end of the installation head, and the installation head is clamped and fixed by the push piece to achieve flexible and stable pressing; after the limit seat is reset, the rotating plate rotates clockwise to drive the vertical guide rail to transition from a vertical state to a horizontal state, and the angle of the installation head is changed to make it aligned with the cable end in the same direction. The installation head is convenient for docking. During the docking process, the installation head is driven to move horizontally close to the cable end through the horizontal sliding of the vertical guide rail. The cable end is clamped by the electric clamp, and the two slides are driven away from each other by the transmission screw, thereby stretching the cable and guiding the two ends of the cable to the corresponding assembly room respectively, so as to achieve accurate docking between the installation head and the cable end. The fixed-point installation of the installation heads at both ends of multiple groups of cables is completed automatically, which is time-saving and efficient. No manual intervention is required, avoiding problems such as joint dislocation and damage caused by human errors, and reducing the danger of operators operating in a small space, improving operational safety. 2. When the mounting head enters the limit seat, the pressure plate returns to its original position under the action of the elastic member, fits and limits the mounting head, and forms a top pressure limit structure to prevent the mounting head from axially loosening or tilting during vertical entry or rotation, thereby playing a role of clamping and preventing loosening; at this time, the airbag in the inner cavity of the limit seat is inflated and expanded under the control of an external air pump, and the expansion of the airbag drives the outer clamping plate to move toward the side wall of the mounting head, so that the mounting head forms a stable clamp inside the limit seat and stably fixes the mounting head; when the electromagnet is energized, its armature is sucked in, driving the connected pressure plate to slide outward, thereby opening the pressure plate, and the mounting head can smoothly pass through the opened pressure plate and move out from the inside of the limit seat; 3. By setting up multiple conveying slots, the installation head reaches the end position of the conveying frame along the conveying slots. At this time, multiple feed ports are blocked by the same blocking plate to avoid deviation during transportation and ensure the fixed-point clamping of the installation head; when the blocking plate is driven by a rotating motor to flip clockwise, the blocking plate changes from a horizontal blocking state to a vertical open state. At this time, the installation head is pushed downward after being clamped, and then enters the limit seat after passing through the through cavity, which is convenient for transferring the installation head to the assembly room; 4. The unwinding rollers are supported by the corresponding support bracket groups. The middle unwinding roller is clamped through sliding. The support bracket groups at both ends synchronously move inwards to complete the clamping of multiple unwinding rollers. When a lifting station slides to the middle of the slide rail, two groups of stroke cylinders are activated to push the entire adjusting seat upwards, lifting the unwinding rollers installed on the support bracket groups to the docking height. The docking frame is driven by the second electric push rod to move inwards. The plug connectors on the docking frame are positioned and clamped with the ends of the unwinding rollers at both ends. Then, the rotating disk drives the multiple interconnected unwinding rollers to rotate synchronously and work simultaneously. After the work is completed, the former lifting station slides to the rear slide rail, and another lifting station slides to the middle on the front slide rail. In the former lifting station, the support bracket groups at both ends are driven by the adjusting seat to synchronously expand outwards, causing the adjacent two unwinding rollers to separate and completing the removal.

[0020] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0021] Please refer to Figures 1-7 As shown, the present invention provides a production fixing device for a radio frequency connector, including a processing chamber 1 installed in the middle of the top surface of a base table. Both sides of the top of the processing chamber 1 are provided with assembly chambers 7, and two alternately used lifting workstations are slidably arranged inside the processing chamber 1; The lifting workstation includes an adjusting seat 13 that lifts and lowers in the vertical direction. A plurality of unwinding rollers 34 are arranged on the upper surface of the adjusting seat 13. One end of the cable passes out from one side of the bottom of the unwinding roller 34, and the other end of the cable passes out from the other side of the top of the unwinding roller 34; Both sides of the top of the inner cavity of the processing chamber 1 are respectively sleeved with sliding seats 8 through two driving screws. The bottom surface of each sliding seat 8 is connected with an electric clamping jaw 11 for clamping the end of the corresponding cable through an electric push rod I; A conveying frame 4 is installed on the upper surface of each assembly chamber 7, and a clamping and pushing unit for positioning the mounting head is arranged to lift inside the conveying frame 4; The clamping and pushing unit includes a plurality of notches 17 arranged on the inner wall surface of the conveying frame 4. A lifting plate 15 pushed by a segmented stroke cylinder twice is arranged at the top of one end of the conveying frame 4. An electric clamping jaw 16 for clamping the mounting head at a fixed point is installed on the bottom surface of the lifting plate 15, and one clamping block of the electric clamping jaw 16 is hidden in the corresponding notch 17; A clamping unit for docking the mounting head and the cable is arranged inside the assembly chamber 7; The clamping unit includes rotating plates 28 rotatably installed on the inner walls of both sides of the assembly chamber 7. Vertical guide rails 29 arranged vertically are installed on the inner wall surfaces of each rotating plate 28. The two vertical guide rails 29 move synchronously. The sliders connected to the outside of the vertical guide rails 29 are connected with a limit seat 22. A pushing member for clamping the mounting head is installed at the bottom of the inner cavity of the limit seat 22. The top of the limit seat 22 is open, and a blocking ring is arranged at the bottom of the limit seat 22; Place the mounting head in the conveying frame 4 and convey it to the end position at a fixed point. The lifting plate 15 moves in two times; During the first movement, the segmented stroke cylinder pushes the lifting plate 15 to move downwards by a certain height. When it moves downwards, the electric clamping jaw 16 is in an open state. One clamping block on the electric clamping jaw 16 moves downwards along the notch 17 until it reaches the upper position of the mounting head, and then the electric clamping jaw 16 clamps the mounting head at a fixed point; Then, the segmented stroke cylinder pushes the lifting plate 15 clamping the mounting head to move downwards again, so that the mounting head enters the assembly chamber 7; Before the installation head enters the assembly chamber 7, since the opening of the limit seat 22 faces upward, the limit seat 22 slides upward along the vertical guide rail 29, so that the limit seat 22 approaches the top of the assembly chamber 7. The installation head is accurately inserted into the limit seat 22 from the open end, and one end of the installation head is blocked by the blocking ring to avoid rigid collision during the insertion process. The installation head is clamped and fixed by the pushing member to achieve flexible and stable pressing, avoiding joint deformation or performance degradation caused by assembly stress; Immediately afterwards, the limit seat 22 returns to its initial position to avoid direct movement interference with the top of the assembly chamber 7 when following the rotation of the rotating plate 28. Then, by rotating the rotating plate 28 clockwise, the vertical guide rail 29 is driven to transition from a vertical state to a horizontal state, thereby driving the limit seat 22 and the clamped installation head to a horizontal posture. By changing the angle of the installation head, it can be smoothly docked with the end of the cable. During the docking process, the installation head is driven to move horizontally closer to the end of the cable by sliding horizontally on the vertical guide rail 29; The end of the cable is clamped by the electric gripper 11. The two sliding seats 8 are driven to move away from each other by the transmission screw rod, thereby stretching the cable, and the two ends of the cable are respectively guided into the corresponding assembly chambers 7 to achieve precise docking of the installation head and the end of the cable; The installation head can be a male head or a female head, and the fixed-point installation of the installation heads at both ends of multiple groups of cables is automatically completed, which is time-saving and efficient; there is no need for manual intervention, avoiding problems such as joint misalignment and damage caused by human errors, and reducing the danger of operators working in a narrow space, improving operation safety.

[0022] Refer to Figure 5 As shown, the pushing member includes an airbag 25 provided in the middle of the inner cavity of the limit seat 22. A clamping plate 24 is provided outside the airbag 25, and elastic pads 23 are provided at both ends of the airbag 25. The end of the elastic pad 23 is fixed to the inner wall of the limit seat 22; A pressing plate 27 for limiting the end of the installation head is provided in the upper part of the inner cavity of the limit seat 22; An electromagnet 26 is installed in the mounting seat outside the limit seat 22. A rod body connected to the electromagnet 26 through an armature is fixed to the outside of the pressing plate 27; During the process of the installation head being sent into the limit seat 22 by the lifting plate 15, the front end of the installation head slides into the inner cavity of the limit seat 22, as Figure 5As shown, the pressing plates 27 on both sides enter the top of the inner cavity of the limiting seat 22, and the electromagnet 26 is in a power-off state. The mounting head first pushes against the pressing plates 27 on both sides, so that the pressing plates 27 slide along the mounting seat in a directional manner and squeeze the elastic member connected to the electromagnet 26 until the mounting head passes through the pressing plates 27 and enters the position of the bottom push member. The pressing plates 27 return to their original positions under the action of the elastic member (such as a spring or a compression pad), fit and limit the mounting head, and form a top pressure limiting structure to prevent the mounting head from axially loosening or tilting during vertical entry or rotation, thereby playing a role of clamping and preventing loosening. At this time, the airbag 25 in the inner cavity of the limit seat 22 is inflated under the control of the external air pump, and the expansion of the airbag 25 drives the outer clamping plate 24 to move toward the side wall of the mounting head, so that the mounting head is stably clamped inside the limit seat 22, stably fixing the mounting head, and avoiding the possibility of scratches, indentations or deformation on the surface of the mounting head caused by traditional rigid clamps. At the same time, the elastic pads 23 at both ends of the airbag 25 play a guiding, buffering and rebounding role, ensuring that the clamping process is flexible and does not damage the surface of the mounting head; When the electromagnet 26 is energized, its armature is sucked in, driving the connected pressing plate 27 to slide outward, thereby opening the pressing plate 27 , and the mounting head can smoothly pass through the opened pressing plate 27 and move out from the interior of the limiting seat 22 .

[0023] See also Figure 1 and Figure 2 As shown, the interior of the conveying frame 4 is provided with a plurality of conveying slots 5 for positioning and conveying the mounting head, and the bottom surface of the end of each conveying slot 5 is provided with a feed port 6, and the inner cavity end of the feed port 6 is rotated by a rotating motor 20 and a blocking plate 19 is installed; The upper surface of the assembly chamber 7 is provided with a through cavity 18 communicating with the feed port 6, and the edge of the through cavity 18 is provided with a storage cavity 21 for the blocking plate 19 to rotate into; When the mounting head is conveyed to the end of the conveying trough 5, the blocking plate 19 is horizontal during this process, that is, the feed port 6 is blocked to ensure the fixed-point clamping of the mounting head; When the blocking plate 19 is driven by the rotating motor 20 to flip clockwise, the blocking plate 19 changes from a horizontal blocking state to a vertically open state. At this time, the mounting head is pushed downward after being clamped, and then enters the limit seat 22 after passing through the through cavity 18.

[0024] See also Figure 2 and Figure 7 As shown, openings 2 are provided on both sides of the processing chamber 1, and two sets of co-linear slide rails 3 are installed on the base; The two lifting stations slide on the corresponding slide rails 3 respectively; When one lifting station is working in the processing chamber 1, the other lifting station is located on the slide rail 3 on the surface of the base, that is, on the side of the processing chamber 1, so as to facilitate the loading of the lifting station. When the previous lifting station completes the processing, the materials are loaded alternately, and the operation is uninterrupted without multiple stops; The lifting station also includes a slide 9 sliding on the slide rail 3, and two sets of synchronously moving stroke cylinders 12 are installed on the top surface of the slide 9, and the push end of the stroke cylinder 12 is fixed to the bottom surface of the adjustment seat 13; The lifting station also includes a plurality of support bracket groups 14 for carrying the unwinding roller 34. The support bracket groups 14 at both ends are threadedly sleeved with the bidirectional screws in the adjustment seat 13, and the support bracket group 14 in the middle slides on the damping guide rail on the adjustment seat 13; Both sides of the top of the inner cavity of the processing chamber 1 are connected by a docking frame 35 connected by two electric push rods installed on the rotating disk, and the inner wall surface of the docking frame 35 is installed with a plug-in piece that is snap-fitted with the end of the unwinding roller 34; The two sets of stroke cylinders 12 on the slide 9 are started, pushing the adjustment seat 13 to rise as a whole, and raising the unwinding roller 34 installed on the support bracket group 14 to the docking height; The motor drives the bidirectional screw to rotate, so that the support brackets 14 at both ends are synchronously opened outward or retracted inward, and the spacing is adjusted to adapt to unwinding rollers 34 of different specifications. In the process of opening outward, the two adjacent unwinding rollers 34 are separated; The docking frame 35 is driven by the electric push rod 2 to move inward, and the plug-in piece on the docking frame 35 is inserted into the end of the unwinding roller 34 to complete the positioning connection and prevent it from loosening. The rotating disk drives the multiple unwinding rollers 34 connected together to rotate synchronously; See also Figure 2 As shown, the unwinding roller 34 rotates counterclockwise to synchronously reel in both ends of the cable, at which point the cable ends and the installation head have been crimped and fixed; the unwinding roller 34 rotates clockwise to synchronously unwind both ends of the cable, facilitating crimping of both ends of the cable with the corresponding installation heads.

[0025] See also Figure 6 As shown, a welding unit 10 for hot-melting and crimping the mounting head and the cable end is provided on one side of the inner wall surface of the assembly chamber 7 adjacent to the locking unit. The welding unit 10 includes two connecting seats 32 driven by a synchronous cylinder. The connecting seats 32 are semi-annular structures. A heating welding plate 33 is fitted on the inner wall surface of each connecting seat 32, and two guide plates 31 are installed on the outer edge of each connecting seat 32. A limiting rod 30 that slides with the corresponding guide plate 31 is installed on the inner wall surface of the assembly chamber 7. The two connecting seats 32 are pushed by the synchronous cylinder, and the guide plate 31 at this time slides in a directional manner on the limit rod 30 to ensure the stable sliding of the connecting seat 32. When the connecting seat 32 is close to and contacts the installation head and the cable end, the heating welding plate 33 is heated to the set temperature, and the plug-in joint is hot-pressed to achieve fusion and crimping. The installation is completed by pressure melting, thereby forming the production of multiple RF connectors; after the welding time reaches the set value, the synchronous cylinder reversely drives the two connecting seats 32 to separate, and the heating welding plate 33 is separated from the contact surface, completing a round of welding connection process between the installation head and the cable.

[0026] A working method of a fixing device for producing a radio frequency connector, the working method comprising the following steps: Step 1: A plurality of mounting heads are conveyed by a conveying groove 5 in a conveying frame 4 on both sides to an end position, the electric gripper II 16 is opened, and the mounting heads move downward along a notch 17 under a first push of a lifting plate 15 to perform fixed-point clamping on the mounting heads; Step 2: After that, a blocking plate 19 rotates and opens, the lifting plate 15 moves downward for the second time, and a limit seat 22 is driven by a vertical guide rail 29 in the vertical direction to a position adjacent to the lower part of a through cavity 18. The mounting heads enter the limit seat 22, and the end parts of the mounting heads are restricted by a pressing plate 27. Through the expansion of an airbag 25, a clamping plate 24 is pushed to clamp the outer walls of the mounting heads; Step 3: Immediately afterwards, the limit seat 22 moves down to an initial height, and then the limit seat 22 rotates clockwise by 90 degrees to align the insertion direction of the mounting heads with the end parts of the cables. At this time, the vertical guide rail 29 becomes in a horizontal state, and the limit seat 22 slides horizontally close to the cable end parts, while the cable end parts slide towards the direction of an assembly chamber 7 under the sliding of a sliding seat 8, thereby completing the insertion of the two end parts of the cables into the corresponding mounting heads; Step 4: A synchronous cylinder is used to push two connecting seats 32 to drive corresponding heating welding plates 33 to be pressed together with the cable end parts inserted into the mounting heads, and the installation is completed through hot melting; Step 5: After that, the docking frames 35 on both sides release the restriction on the lifting station, the lifting station descends in height, and slides out of the interior of a processing chamber 1 on a slide rail 3. The lifting station on another slide rail 3 slides into the processing chamber 1 until it rises to the position of the docking frame 35 and is alternately used for processing.

[0027] When the present invention is in use, by setting a clamping and pushing unit, a locking unit and a slidable electric gripper 11, during the first movement, the mounting head is clamped at a fixed point first; during the second push, the clamped mounting head moves downward into the assembly chamber 7; when the limit seat 22 slides close to the top of the assembly chamber 7, the mounting head is accurately inserted into the limit seat 22 from the open end, one end of the mounting head is blocked by the blocking ring, and the mounting head is clamped and fixed by the pushing member, realizing flexible and stable pressing; after the limit seat 22 resets, the rotating plate 28 rotates clockwise, driving the vertical guide rail 29 to transition from the vertical state to the horizontal state, by changing the angle of the mounting head, enabling it to be smoothly docked with the end of the cable. During the docking process, through the lateral sliding of the vertical guide rail 29, the mounting head is driven to move horizontally close to the end of the cable; while the end of the cable is clamped by the electric gripper 11, the two sliding seats 8 are driven to move away from each other by the transmission screw rod, thereby stretching the cable, and the two ends of the cable are respectively guided into the corresponding assembly chambers 7, realizing the precise docking of the mounting head and the end of the cable; the automatic installation of the mounting heads at fixed points at both ends of multiple cables is completed, which is time-saving and efficient; there is no need for manual intervention, avoiding problems such as joint misalignment and damage caused by human errors, and reducing the danger of operators operating in a narrow space, improving the operation safety; When the mounting head enters the limit seat 22, the pressing plate 27 returns to its position under the action of the elastic member, fits and limits the mounting head, forming a top pressing and limiting structure, preventing the mounting head from axially loosening or tilting during the vertical entry or rotation, playing the role of clamping and anti-loosening; at this time, the airbag 25 in the inner cavity of the limit seat 22 is inflated under the control of an external air pump, and the inflation of the airbag 25 drives the outer clamping plate 24 to move towards the side wall of the mounting head, enabling the mounting head to form a stable clamping inside the limit seat 22 and stably fixing the mounting head; when the electromagnet 26 is energized, its armature is sucked in, driving the connected pressing plate 27 to slide outwards, thereby opening the pressing plate 27, and the mounting head can smoothly pass through the opened pressing plate 27 and move out from the inside of the limit seat 22; By setting a plurality of conveying grooves 5, the mounting head reaches the end position of the conveying frame 4 along the conveying grooves 5. At this time, a plurality of feeding ports 6 are blocked by the same blocking plate 19, avoiding deviation during transportation and ensuring the fixed-point clamping of the mounting head; when the blocking plate 19 is driven by the rotating motor 20 to rotate clockwise, the blocking plate 19 changes from the horizontal blocking state to the vertical opening state. At this time, the mounting head is pushed downward after being clamped, and then enters the limit seat 22 through the through cavity 18, facilitating the transfer of the mounting head into the assembly chamber 7; The unwinding roller 34 is supported by the corresponding support bracket group 14. The middle unwinding roller 34 is clamped by sliding. The support bracket groups 14 at both ends are synchronously retracted inward to complete the clamping of multiple unwinding rollers 34. When a lifting station slides to the middle of the slide rail 3, the two sets of stroke cylinders 12 are activated to push the adjusting seat 13 to rise as a whole, lifting the unwinding roller 34 installed on the support bracket group 14 to the docking height. The docking frame 35 is driven by the second electric push rod to move inward. The plug-in parts on the docking frame 35 are positioned and clamped with the ends of the unwinding rollers 34 at both ends. Then, the rotating disk drives the multiple interconnected unwinding rollers 34 to rotate synchronously and work simultaneously. After the work is completed, the former lifting station slides onto the rear slide rail 3, and another lifting station slides to the middle on the front slide rail 3. In the former lifting station, the support bracket groups 14 at both ends driven by the adjusting seat 13 are synchronously opened outward, so that the adjacent two unwinding rollers 34 are separated to complete the removal.
