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, up to 18GHz or higher. They are mainly used in radar, communications, 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 for the positioning accuracy and clamping stability of the 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 downward with the opening corresponding to the female head and inserted into the interior of the female head to assemble into a RF connector. No manual assembly is required, and the production speed is accelerated.

[0004] In traditional cable docking methods, the connection between the installation head (such as male and female heads) and the cable end often requires manual alignment and operation, which leads to problems such as inaccurate alignment, large angle errors, and incomplete insertion. In addition, manual operation is inefficient, 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:

[0007] The connection between mounting heads (such as male and female connectors) and cable ends often requires manual alignment and operation, which can lead to problems such as inaccurate alignment, large angle errors, and incomplete insertion. Furthermore, manual operation is inefficient and not conducive to mass production.

[0008] The lack of a stable positioning and limiting mechanism during the plug-in process, especially during the vertical insertion, flipping or corner transition of the installation head, may cause problems such as axial looseness and joint warping, affecting the connection quality.

[0009] The present invention can be achieved through the following technical solutions:

[0010] A radio frequency connector production fixture comprises a processing chamber mounted in the middle of a base top surface, with assembly chambers provided on both sides of the top of the processing chamber, and two lifting stations for alternating use being slidably provided inside the processing chamber;

[0011] The lifting station includes an adjustment seat that can be lifted in the vertical direction. A plurality of unwinding rollers are provided on the upper surface of the adjustment seat.

A clamping block of the electric clamping jaw 2 is hidden in the corresponding notch.

[0015] Inside the assembly chamber is a locking unit that connects the mounting head to the cable;

[0016] The locking unit includes a rotating plate rotatably mounted on the inner walls on both sides of the assembly chamber. A vertical guide rail is installed on the inner wall surface of each rotating plate. The two vertical guide rails move synchronously. The slider connected to the outside of the vertical guide rail is connected to the limit seat. A push piece for clamping the installation head is installed at the bottom of the inner cavity of the limit seat. The top of the limit seat is open, and a blocking ring is provided at the bottom of the limit seat.

[0017] A further technical improvement of the present invention is that the push member includes an airbag arranged in the middle of the inner cavity of the limit seat, a clamping plate is provided on the outside of the airbag, and elastic pads are provided on both end edges of the airbag, and the ends of the elastic pads are fixed to the inner wall of the limit seat.

[0018] A further technical improvement of the present invention is that: a pressure plate for limiting the end of the mounting head is provided on the upper portion of the inner cavity of the limiting seat;

[0019] An electromagnet is installed in the mounting seat outside the limit seat, and a rod body connected to the electromagnet through the armature is fixed to the outer side of the pressure plate.

[0020] A further technical improvement of the present invention is that: a plurality of conveying troughs are provided inside the conveying frame for positioning and conveying the mounting head, and a feed port is provided on the bottom surface of the end of each conveying trough, and a blocking plate is installed at the inner end of the feed port which is rotated by a rotating motor;

[0021] A through cavity communicated with the feed port is provided on the upper surface of the assembly chamber, and a storage cavity for the blocking plate to rotate into is provided at the edge of the through cavity.

[0022] A further technical improvement of the present invention is that: openings are provided on both sides of the processing chamber, and two sets of collinearly arranged slide rails are installed on the base;

[0023] The two lifting stations slide on corresponding slide rails respectively;

[0024] The lifting station also includes a slide sliding on the slide rail, the top surface of the slide is installed with two groups of synchronously moving stroke cylinders, and the pushing ends of the stroke cylinders are fixed to the bottom surface of the adjustment seat.

[0025] A further technical improvement of the present invention is that the lifting station also includes multiple support bracket groups for carrying 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.

[0026] 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 engages with the end of the unwinding roller.

[0027] 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;

[0028] The welding unit includes two connecting seats driven by synchronous cylinders. The connecting seats are semi-annular structures. The inner wall surface of each connecting seat is fitted with a heating welding plate, and the outer edge of each connecting seat is fitted with two guide plates. The inner wall surface of the assembly chamber is fitted with a limit rod that slides with the corresponding guide plate.

[0029] A working method for a radio frequency connector production fixture, the working method comprising the following steps:

[0030] Step 1: Multiple mounting heads are transported to the end position by the conveying slots in the conveying racks on both sides. The electric clamp 2 opens and moves down along the notched slot with one push of the lifting plate to clamp the mounting heads at a fixed point.

[0031] Step 2: After that, the blocking plate rotates open, the lifting plate moves down for the second time, and the limit seat is driven by the vertical guide rail to the lower position of the through cavity. The mounting head enters the limit seat and is restricted by the pressure plate on the end of the mounting head. The expansion of the airbag pushes the clamping plate to clamp the outer wall of the mounting head.

[0032] Step 3: Next, the limit seat moves down to its initial height, and then rotates 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. The cable end slides toward the assembly chamber under the sliding of the slide, thereby completing the plugging of the two ends of the cable with the corresponding installation heads;

[0033] Step 4: Use the synchronous cylinder to push the two connecting 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;

[0034] Step 5. The docking frames on both sides then release the restrictions on the lifting station. The lifting station descends in height and slides out of the processing room on one slide rail. 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.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 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 causes the clamped installation head to 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 installed 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, driving the vertical guide rail to transition from a vertical state to a horizontal state, and by changing the angle of the installation head, it is aligned with the cable end. The docking process is convenient. During the docking process, the installation head moves 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 transmission screw drives the two slides away from each other, thereby stretching the cable and guiding the two ends of the cable into the corresponding assembly chamber to achieve precise docking between the installation head and the cable end. The automatic completion of the fixed-point installation of the installation heads at both ends of multiple groups of cables is time-saving and efficient. No human intervention is required, avoiding problems such as joint dislocation and damage caused by human error, and reducing the danger of operators operating in confined spaces, thereby improving operational safety.

[0037] 2. When the mounting head enters the limit seat, the pressure plate returns to its position under the action of the elastic member, fits and limits the mounting head, forming a top pressure limit structure to prevent the mounting head from axially loosening or tilting during vertical entry or rotation, playing the role of clamping and preventing loosening; at this time, the airbag in the inner cavity of the limit seat is inflated under the control of an external air pump. 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 of the interior of the limit seat;

[0038] 3. By setting up multiple conveying troughs, the installation head moves along the conveying troughs to the end position of the conveying frame. 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 vertically 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 facilitates the transfer of the installation head to the assembly room.

[0039] 4. The unwinding roller is supported by the corresponding support bracket group, and the middle unwinding roller is connected by sliding. The support bracket groups at both ends are synchronously retracted inward to complete the connection of multiple unwinding rollers. When one lifting station slides to the middle of the slide rail, the two sets of stroke cylinders are started to push the adjustment seat to rise as a whole, and the unwinding roller installed on the support bracket group is raised to the docking height. The docking frame is driven inward by the second electric push rod, and the connector on the docking frame is positioned and connected with the end portions of the unwinding rollers at both ends, and then the rotating disk drives multiple connected unwinding rollers to rotate synchronously and work at the same time. After completion, the former lifting station slides to the slide rail on the rear side, and the other lifting station slides to the middle on the slide rail on the front side. In the former lifting station, the support bracket groups at both ends are driven by the adjustment seat to open synchronously outward, so that the two adjacent unwinding rollers are disengaged and the dismantling is completed.

[0049] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0050] See also Figure 1-Figure 7 As shown, the present invention provides a RF connector production fixture, comprising a processing chamber 1 installed in the middle of the top surface of a base, an assembly chamber 7 is provided on both sides of the top of the processing chamber 1, and two lifting stations for alternating use are slidably provided inside the processing chamber 1;

[0051] The lifting station includes an adjustment seat 13 that can be lifted in the vertical direction. A plurality of unwinding rollers 34 are provided on the upper surface of the adjustment seat 13. One end of the cable passes through one side of the bottom of the unwinding roller 34, and the other end of the cable passes through the other side of the top of the unwinding roller 34.

[0052] The top of the inner cavity of the processing chamber 1 is respectively provided with a slide 8 through two transmission screws, and the bottom surface of each slide 8 is connected to an electric clamping claw 11 for clamping the corresponding cable end through an electric push rod;

[0053] A conveyor frame 4 is installed on the upper surface of each assembly chamber 7, and a clamping and pushing unit for positioning the assembly head is provided inside the conveyor frame 4;

[0054] The clamping and pushing unit includes a plurality of notches 17 provided on the inner wall surface of the conveyor frame 4. A lifting plate 15 is provided on the top of one end of the conveyor frame 4 and is pushed twice by a segmented stroke cylinder. The bottom surface of the lifting plate 15 is installed with an electric clamping jaw 2 16 for clamping the mounting head at a fixed point. A clamping block of the electric clamping jaw 2 16 is hidden in the corresponding notch 17.

[0055] The interior of the assembly chamber 7 is provided with a locking unit for docking the mounting head with the cable;

[0056] The locking unit includes a rotating plate 28 rotatably mounted on the inner walls of both sides of the assembly chamber 7. A vertical guide rail 29 is mounted on the inner wall surface of each rotating plate 28. The two vertical guide rails 29 move synchronously. The slider connected to the outside of the vertical guide rail 29 is connected to the limit seat 22. The bottom of the inner cavity of the limit seat 22 is equipped with a push piece for clamping the installation head. The top of the limit seat 22 is open, and the bottom of the limit seat 22 is provided with a blocking ring.

[0057] The mounting head is placed in the conveying frame 4 and conveyed to the end position at a fixed point. The lifting plate 15 moves twice.

[0058] During one movement, the lifting plate 15 is pushed down by the segmented stroke cylinder. When it moves down, the electric clamp 16 is in the open state, and a clamping block on the electric clamp 16 moves downward along the notch 17 until it reaches the upper position of the mounting head. Then the electric clamp 16 clamps the mounting head at a fixed point.

[0059] Then, the segmented stroke cylinder pushes the lifting plate 15 holding the mounting head downward again, so that the mounting head enters the assembly chamber 7;

[0060] Before the mounting 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 is close to the top of the assembly chamber 7. The mounting head is accurately installed into the limit seat 22 from the open end. The blocking ring blocks one end of the mounting head to avoid rigid collision of the mounting head during the insertion process. The mounting head is clamped and fixed by the push piece to achieve flexible and stable pressing, thereby avoiding deformation or performance degradation of the joint due to assembly stress.

[0061] Then, the limit seat 22 returns to its initial position to avoid directly following the rotation of the rotating plate 28 and interfering with the top of the assembly chamber 7. The vertical guide rail 29 is driven to transition from a vertical state to a horizontal state by the clockwise rotation of the rotating plate 28, thereby driving the limit seat 22 and the clamped mounting head to a horizontal state. By changing the angle of the mounting head, it is smoothly docked with the cable end. During the docking process, the mounting head is driven to move laterally closer to the cable end by sliding laterally on the vertical guide rail 29.

[0062] The cable ends are clamped by electric clamps 11, and the two slides 8 are driven away from each other by the transmission screw, thereby stretching the cable and guiding the two ends of the cable into the corresponding assembly chambers 7, so as to achieve precise docking between the installation head and the cable ends;

[0063] The installation heads can be either male or female, and can automatically complete the fixed-point installation of the installation heads at both ends of multiple groups of cables, saving time and efficiency. Without the need for human intervention, problems such as connector dislocation and damage caused by human errors can be avoided, and the danger of operators operating in confined spaces can be reduced, thereby improving operational safety.

[0064] See Figure 5 As shown, the push member includes an airbag 25 provided in the middle of the inner cavity of the limiting seat 22, a clamping plate 24 is provided on the outer side of the airbag 25, and elastic pads 23 are provided on both end edges of the airbag 25, and the ends of the elastic pads 23 are fixed to the inner wall of the limiting seat 22;

[0065] A pressure plate 27 is provided on the upper portion of the inner cavity of the limiting seat 22 to limit the end of the mounting head;

[0066] An electromagnet 26 is installed in the mounting seat outside the limit seat 22, and the rod body connected to the electromagnet 26 through the armature is fixed to the outer side of the pressure plate 27;

[0067] When the mounting head is sent into the limiting seat 22 by the lifting plate 15, the front end of the mounting head slides into the inner cavity of the limiting seat 22. Figure 5 As shown, the pressure plates 27 on both sides enter the top of the inner cavity of the limit seat 22, and the electromagnet 26 is in the off state. The mounting head first pushes against the pressure plates 27 on both sides, so that the pressure 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 pressure plates 27 and enters the position of the bottom push member. The pressure plates 27 return to their original position under the action of the elastic member (such as a spring or compression pad), fit and limit the mounting head, forming a top pressure limit structure to prevent the mounting head from axially loosening or tilting during vertical entry or rotation, thereby playing the role of clamping and preventing loosening.

[0068] 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. 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. At the same time, it prevents the traditional rigid clamp from causing scratches, indentations or deformation on the mounting head surface. 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 mounting head surface.

[0069] 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 .

[0070] See Figure 1 and Figure 2 As shown, the interior of the conveying frame 4 is provided with a plurality of conveying troughs 5 for positioning and conveying the mounting head. The bottom surface of the end of each conveying trough 5 is provided with a feed port 6. The inner end of the feed port 6 is rotated by a rotating motor 20 and a blocking plate 19 is installed.

[0071] 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;

[0072] When the mounting head is transported to the end of the conveying trough 5, the blocking plate 19 is in a horizontal position during this process, that is, the feed port 6 is blocked to ensure the fixed-point clamping of the mounting head;

[0073] 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.

[0074] See Figure 2 and Figure 7 As shown, openings 2 are provided on both sides of the processing chamber 1, and two sets of collinear slide rails 3 are installed on the base;

[0075] The two lifting stations slide on the corresponding slide rails 3 respectively;

[0076] 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, which is convenient for loading the lifting station. When the previous lifting station completes processing, the loading is alternated and the operation is uninterrupted without multiple stops;

[0077] The lifting station also includes a slide 9 that slides on the slide rail 3. Two sets of synchronously moving stroke cylinders 12 are installed on the top surface of the slide 9. The pushing end of the stroke cylinder 12 is fixed to the bottom surface of the adjustment seat 13.

[0078] 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 connected to the bidirectional screw 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;

[0079] Both sides of the top of the inner cavity of the processing chamber 1 are connected by two electric push rods installed on the rotating disk. The inner wall surface of the docking frame 35 is equipped with a plug-in component that engages with the end of the unwinding roller 34;

[0080] 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;

[0081] The motor drives the bidirectional screw to rotate, causing the support brackets 14 at both ends to open outward or close inward synchronously, and adjust the spacing to adapt to unwinding rollers 34 of different specifications. During the outward opening process, the two adjacent unwinding rollers 34 are separated;

[0082] The docking frame 35 is driven by the electric push rod 2 to move inward, and the connector 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;

[0083] See 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.

[0084] See Figure 6 As shown, a welding unit 10 for hot-melt-bonding the mounting head and the cable end is provided on one side of the inner wall 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 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 is installed on the inner wall of the assembly chamber 7 to slide with the corresponding guide plate 31.

[0085] The two connecting seats 32 are pushed by the synchronous cylinder. At this time, the guide plate 31 slides in a direction on the limit rod 30 to ensure the stable sliding of the connecting seat 32. When the connecting seat 32 approaches 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 drives the two connecting seats 32 to separate in the reverse direction, 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.

[0086] A working method for a radio frequency connector production fixture, the working method comprising the following steps:

[0087] Step 1: Multiple mounting heads are transported to the end position by the conveying slots 5 in the conveying racks 4 on both sides. The electric clamp 2 16 opens and moves down along the notch 17 with one push of the lifting plate 15 to clamp the mounting heads at a fixed point.

[0088] Step 2: After that, the blocking plate 19 rotates open, and the lifting plate 15 moves down a second time. Driven by the vertical guide rail 29, the limiting seat 22 is adjacent to the lower position of the through cavity 18. The mounting head enters the limiting seat 22 and is restrained by the pressing plate 27 on the end of the mounting head. The expansion of the airbag 25 pushes the clamping plate 24 against the outer wall of the mounting head.

[0089] Step 3: The limiting seat 22 is then moved down to its initial height, and then rotated 90 degrees clockwise to align the plugging direction of the installation head with the end of the cable. At this time, the vertical guide rail 29 becomes horizontal, and the limiting seat 22 slides horizontally close to the end of the cable. The end of the cable slides toward the assembly chamber 7 under the sliding of the slide 8, thereby completing the plugging of the two ends of the cable with the corresponding installation heads.

[0090] Step 4: Use the synchronous cylinder to push the two connecting seats 32, drive the corresponding heating welding plate 33 and the cable end of the plug-in installation head to press together, and complete the installation by hot melting;

[0091] Step 5. The docking frames 35 on both sides then release the restrictions on the lifting station. The lifting station descends in height and slides out of the interior of the processing chamber 1 on one slide rail 3. The lifting station on the other slide rail 3 slides into the processing chamber 1 until the height reaches the position of the docking frame 35 and is used alternately for processing.

[0092] When the present invention is in use, by providing a clamping and pushing unit, a locking unit and a slidable electric clamping claw 11, the mounting head is first clamped at a fixed point during the first movement; the second push causes the clamped mounting head to move down and enter the assembly chamber 7; when the limit seat 22 slides close to the top of the assembly chamber 7, the mounting head is accurately loaded into the limit seat 22 from the open end, and the blocking ring blocks one end of the mounting head, and the mounting head is clamped and fixed by the push piece to achieve flexible and stable pressing; after the limit seat 22 is reset, the rotating plate 28 rotates clockwise, driving the vertical guide rail 29 to transition from a vertical state to a horizontal state, and by changing the angle of the mounting head, It docks smoothly with the cable end. During the docking process, the lateral sliding of the vertical guide rail 29 drives the installation head to move laterally close to the cable end. The cable end is clamped by the electric clamp 11, and the two slides 8 are driven away from each other by the transmission screw, thereby stretching the cable and guiding the two ends of the cable into the corresponding assembly chamber 7, thereby achieving precise 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, saving time and efficiency. No human intervention is required, avoiding problems such as joint dislocation and damage caused by human error, and reducing the danger of operators operating in a small space, thereby improving operational safety.

[0093] When the mounting head enters the limit seat 22, the pressure plate 27 returns to its original position under the action of the elastic member, fits and limits the mounting head, forming a top pressure limit structure, preventing the mounting head from axially loosening or tilting during vertical entry or rotation, playing the role of clamping and preventing loosening; at this time, the air bag 25 in the inner cavity of the limit seat 22 is inflated under the control of an external air pump, and the expansion of the air bag 25 drives the outer clamping plate 24 to move toward the side wall of the mounting head, so that the mounting head forms a stable clamp inside the limit seat 22, stably fixing the mounting head; when the electromagnet 26 is energized, its armature is sucked in, driving the connected pressure plate 27 to slide outward, thereby opening the pressure plate 27, and the mounting head can smoothly pass through the opened pressure plate 27 and move out of the interior of the limit seat 22;

[0094] By providing multiple conveying troughs 5, the mounting head reaches the end position of the conveying frame 4 along the conveying trough 5. At this time, the multiple feed ports 6 are blocked by the same blocking plate 19 to avoid deviation during transportation and 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 passes through the through cavity 18 and enters the limit seat 22, which facilitates the transfer of the mounting head to the assembly chamber 7.

[0095] The unwinding roller 34 is supported by the corresponding support bracket group 14, and the middle unwinding roller 34 is connected by sliding. The support bracket groups 14 at both ends are synchronously retracted inwardly to complete the connection of multiple unwinding rollers 34. When one lifting station slides to the middle of the slide rail 3, the two sets of stroke cylinders 12 are started, pushing the adjusting seat 13 to rise as a whole, and the unwinding roller 34 installed on the support bracket group 14 is raised to the docking height, and the electric push rod 2 drives the docking frame 35 to move inward, and the plug-in parts on the docking frame 35 are positioned and engaged with the end parts of the unwinding rollers 34 at both ends, and then the rotating disk drives the multiple unwinding rollers 34 connected together to rotate synchronously.
