Description

Technical Field

[0001] This invention relates to the field of antenna bonding technology, specifically to a bonding device and method for antennas on flexible circuit boards. Background Technology

[0002] The bonding between the mobile phone frame and the flexible printed circuit board (FPC) antenna is a key process to ensure the performance of mobile phone wireless communication (such as 5G, WiFi, Bluetooth, etc.). Its core goal is to achieve the synergistic effect of the antenna and the frame through tight and precise bonding (such as using the frame as a ground or radiator), while avoiding signal interference or performance degradation. The bonding between the mobile phone frame and the FPC antenna requires a strict bonding process to ensure that the antenna and the frame work closely together, ultimately achieving stable wireless communication performance.

[0003] Chinese patent CN111587064B discloses an automated antenna bonding device, including a frame, a feeding module, and at least one bonding module. The bonding module includes a feeding component for placing the antenna, an adjustment component for adjusting the antenna, and a bonding component for gripping and bonding the antenna. The adjustment component includes a mounting bracket, an antenna positioning block, a power module, and an adjustment module. The adjustment module includes a first limiting block and a second limiting block. The first limiting block and the second limiting block are driven by the power module to touch the antenna and push it. However, during the bonding process, the positioning effect of the components is poor, resulting in insufficient antenna bonding precision.

[0004] Furthermore, after prolonged use, due to the friction and vibration of the components, impurities and particles will accumulate inside the fixture, affecting the flatness of the components and causing the antenna to shift during bonding, thus affecting the bonding effect. In addition, after prolonged use, the wear of the components will lead to a decrease in positional accuracy, causing the component to be bonded to tilt upwards at one end, resulting in a large error in the bonding angle and making it difficult to bond effectively. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a bonding device and method for flexible circuit board antennas, which can effectively improve the positioning accuracy and monitor the condition of impurities and particles inside the fixture.

The bottom of the slide block is provided with a connecting seat, which is connected to the transmission belt.

[0011] Preferably, both ends of the slide are provided with lifting cylinders, the top extension end of the lifting cylinder is provided with a clamping cylinder through the lifting seat, and the extension end of the clamping cylinder is provided with a clamping block through the fixed seat. The clamping block is made of rubber and has a strip groove on its side.

[0012] Preferably, the fixing base is a hollow structure, and the fixing base is connected to an external air extraction system through an air extraction pipe. An air inlet is provided on the side of the clamping block, and the air inlet is connected to the fixing base and the air inlet is connected to the strip groove.

[0013] Preferably, the positioning component includes a movable seat, which is sleeved on the support column and located at the bottom of the slot seat. Both ends of the bottom of the movable seat are provided with end positioning cylinders. The telescopic ends of the end positioning cylinders are provided with end positioning blocks through the positioning seat. The top of the end positioning block is provided with a first flange laterally. The end positioning blocks at both ends are respectively located at both ends of the slot seat. The end positioning blocks are hollow structures. The end positioning blocks are connected to an external air supply system through an air supply pipe. The bottom of the first flange is provided with an air guide hole communicating with the interior of the end positioning block. Both sides of the movable seat are provided with side positioning cylinders. The telescopic end of the side positioning cylinder is provided with a side positioning block through a support. The top of the side positioning block is provided with a second flange in the horizontal direction. The side positioning blocks on both sides are respectively located on both sides of the slot seat.

[0014] Preferably, the positioning component further includes a clamping cylinder, which is mounted on the frame plate, and the top telescopic end of the clamping cylinder is fixedly connected to the movable seat.

[0015] This invention also discloses a bonding method for flexible circuit board antennas, comprising the following steps: S1. First, the lifting mechanism on one side drives the pneumatic clamping mechanism to pick up the part to be bonded from the bottom of the conveyor belt and then rises back. The belt conveying mechanism drives the transmission belt to run, which drives the slide and clamping block of the conveying component to move. The clamping block clamps the part to be bonded and transfers it to the top of the slot. The lifting cylinder retracts to put the part to be bonded into the groove of the slot. Then the lifting cylinder and clamping cylinder reset. S2. Next, the end positioning cylinder drives the end positioning block to abut against both ends of the groove seat, and the side positioning cylinder drives the side positioning block to abut against both sides of the groove seat. The pressing cylinder retracts and drives the movable seat to move down, so that the first flange of the end positioning block and the second flange of the side positioning block press against the end and side top surface of the part to be bonded respectively. The elastic extrusion at the bottom of the groove seat generates a reverse force to assist in positioning, thereby achieving the pressing and positioning of the part to be bonded. S3. Then, the robotic arm drives the bonding head to the feeding mechanism through the rotary lifting mechanism, adsorbs the antenna material, and transfers the antenna to the part to be bonded. The rotary lifting mechanism adjusts the position and angle of the antenna and then bonds it to the part to be bonded. The moving cylinder and the adjusting cylinder adjust the position of the auxiliary seat so that it corresponds to the two ends of the antenna. The electric telescopic rod extends and drives the auxiliary seat to push against the two ends of the antenna to prevent it from tilting. The pressure sensor monitors the pressure to prevent damage and ensures bonding accuracy. S4. Finally, the positioning component releases its position, the clamping block clamps the bonded part, and the lifting cylinder removes it from the slot. The belt conveyor drives the transmission belt, which, together with the conveyor component and the lifting mechanism on the other side, transfers the bonded part to the top of the material trough on the other side. The lifting mechanism on that side clamps the part and places it back onto the conveyor belt through the material trough. At the same time, the feeding step is repeated for the next cycle.

[0016] Compared with the prior art, the present invention has the following advantages: 1. This invention achieves multi-dimensional precise positioning through positioning components. The end positioning cylinder drives the end positioning block to abut against both ends of the groove seat, and the side positioning cylinder drives the side positioning block to abut against both sides of the groove seat. In conjunction with the pressing cylinder, the movable seat is moved down, so that the first flange and the second flange press against the end and side top surface of the part to be bonded, respectively. At the same time, the elastic compression at the bottom of the groove seat generates a reverse force to assist positioning, which greatly improves the positioning stability and accuracy of the part to be bonded.

[0017] 2. This invention utilizes the air inlet of the clamping block in the conveying assembly in conjunction with the external air extraction system. The airflow ejected from the air guide hole of the positioning block at the joint end can gather and suck up impurities and particles in the slot to the center, thus avoiding impurities from affecting the flatness and bonding effect of the slot and reducing bonding offset caused by impurities.

[0018] 3. This invention uses a robotic arm to drive an auxiliary seat to detect the placement status of the component to be bonded. If a misalignment occurs, the clamping cylinder and belt conveyor mechanism can be used to correct the misalignment along the width and length directions respectively, compensating for the loss of equipment precision after long-term use and the problem of the slight gap between the component and the slot, thus ensuring the placement accuracy of the component.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] Please see Figure 1-10 The present invention provides a flexible circuit board antenna bonding device, including a stand 1, a robotic arm 3 on the other side of the top of the stand 1, a rotating lifting mechanism 301 on the robotic arm 3, and a feeding mechanism 2 on the top of the stand 1.

[0024] Specifically, the robotic arm 3 is preferably a six-axis robotic arm, the rotary lifting mechanism 301 is preferably the rotary lifting motion mechanism disclosed in CN113628990B, used to realize the rotation and lifting action of the bonding component 4, and the feeding mechanism 2 is used to convey the formed antenna, the antenna structure as follows. Figure 10 As shown, the robotic arm 3 drives the bonding component 4 to move through the rotary lifting mechanism 301, and uses the bonding component 4 to adsorb the antenna on the feeding mechanism 2 for transfer.

[0025] A frame plate 101 is provided on one side of the top of the frame 1. Material troughs 102 are provided on both sides of the frame plate 101. Lifting mechanisms 6 are provided at both ends of the frame plate 101. A pneumatic clamping mechanism 601 is provided on the lifting mechanism 6. The pneumatic clamping mechanism 601 corresponds to the material trough 102.

[0026] Specifically, the material troughs 102 on both sides of the frame plate 101 are used for loading and unloading the parts to be bonded. The lifting mechanism 6 on one side drives the pneumatic clamping mechanism 601 on the other side to move downward through the material trough 102, clamp the parts to be bonded from the conveyor belt at the bottom of the frame plate 101 and then rise back. After bonding is completed, the lifting mechanism 6 on the other side drives the pneumatic clamping mechanism 601 on the other side to lift and clamp the bonded parts on the conveyor assembly 7, move downward through the material trough 102 on the other side and then put them back on the lower conveyor belt.

[0027] The support plate 101 has a support column 103 in the middle, and a groove 104 is provided at the top of the support column 103. The groove 104 is used to place the parts to be bonded. The groove on the top surface of the groove 104 is adapted to the parts to be bonded. The bottom of the groove 104 is preferably made of elastic material.

[0028] The top of the frame plate 101 is provided with a belt conveyor mechanism 5, which includes two symmetrically arranged transmission belts 501.

[0029] Specifically, the transmission belt 501 drives the transmission assembly 7 to perform horizontal reciprocating linear motion by its own operation.

[0030] The bottom of the rotary lifting mechanism 301 is provided with a bonding component 4. The bonding component 4 includes a mounting base 401. The mounting base 401 is located at the bottom end of the rotary lifting mechanism 301. One end of the bottom of the mounting base 401 is provided with a bonding head 402. The side of the bonding head 402 is provided with a visual sensor 403. The visual sensor 403 is used to detect the bonding position accuracy of the antenna.

[0031] Specifically, the bonding head 402 has a negative pressure adsorption function, which is used to adsorb and fix the antenna to be bonded.

[0032] The bottom surface of the mounting base 401 is provided with a movable cylinder 404. The telescopic end of the movable cylinder 404 is provided with a movable seat 405. The movable seat 405 and the contact head 402 are far apart from each other. Both ends of the movable seat 405 are slidably connected with movable plates 406. The movable plates 406 have an L-shaped structure. The bottom ends of the movable plates 406 on both sides are provided with movable grooves 407. An auxiliary seat 408 is provided in the movable groove 407. An electric telescopic rod 409 is provided between the auxiliary seat 408 and the top of the movable groove 407. A pressure sensor is provided between the auxiliary seat 408 and the electric telescopic rod 409. The auxiliary seat 408 is slidably connected to the movable groove 407.

[0033] Specifically, the telescopic end of the movable cylinder 404 drives the movable seat 405 to move, which in turn drives the movable plates 406 on both sides to move linearly, thereby realizing the linear movement of the auxiliary seat 408 and adjusting the position of the auxiliary seat 408. The height of the auxiliary seat 408 is adjusted by telescopically extending the electric telescopic rod 409.

[0034] The movable cylinder 404 is provided with guide rails 410 on both sides, and guide seats 411 are slidably connected on the guide rails 410. An adjusting cylinder 412 is provided on the guide seat 411, and the extension end of the adjusting cylinder 412 is fixedly connected to the side of the movable plate 406.

[0035] Specifically, the sliding connection between the guide seat 411 and the guide rail 410 limits and guides the linear movement of the movable plate 406. Since the end of the movable seat 405 is slidably connected to the end of the movable plate 406, the extension and retraction of the adjusting cylinder 412 drives the movable plate 406 to move horizontally, thereby adjusting the distance between the auxiliary seats 408 on both sides.

[0036] Both sides of the frame plate 101 are provided with a conveying assembly 7 that is linked to the transmission belt 501. The conveying assembly 7 includes two corresponding slide rails 701. The two slide rails 701 are respectively located on both sides of the frame plate 101. A slide seat 702 is slidably connected to the slide rails 701 on both sides. The slide seat 702 has an L-shaped structure. A connecting seat 703 is provided at the bottom of the slide seat 702. The connecting seat 703 is connected to the transmission belt 501.

[0037] Specifically, after the connecting seat 703 engages with the transmission belt 501, the operation of the transmission belt 501 drives the slide seat 702 to slide linearly along the slide rail 701, while simultaneously driving the lifting cylinder 704, lifting seat 705, clamping cylinder 706 and clamping block 707 to move linearly, so as to realize the transfer and transmission of the parts to be bonded.

[0038] Both ends of the slide 702 are provided with lifting cylinders 704. The top extension end of the lifting cylinder 704 is provided with a clamping cylinder 706 via the lifting seat 705. The extension end of the clamping cylinder 706 is provided with a clamping block 707 via the fixed seat 708. The clamping block 707 is made of rubber and has a strip groove 709 on its side.

[0039] Furthermore, the lifting cylinder 704 is used to drive the clamping cylinder 706 and the clamping block 707 to rise and fall through the lifting seat 705. The clamping cylinder 706 drives the clamping block 707 to extend and retract and cooperate with the clamping block 707 on the other side to clamp the parts to be bonded. The clamping block 707 is made of rubber to protect the parts to be bonded and prevent damage. The strip groove 709 is used to increase friction and improve the stability of transportation.

[0040] The middle part of the frame plate 101 is provided with a positioning component 8 that cooperates with the slot seat 104. The positioning component 8 includes a movable seat 801, which is sleeved on the support column 103 and located at the bottom of the slot seat 104. Both ends of the bottom of the movable seat 801 are provided with end positioning cylinders 802. The telescopic end of the end positioning cylinder 802 is provided with an end positioning block 804 through the positioning seat 803. The top of the end positioning block 804 is provided with a first flange 805 laterally. The end positioning blocks 804 at both ends are located at both ends of the slot seat 104.

[0041] The positioning assembly 8 also includes a clamping cylinder 811, which is mounted on the frame plate 101. The top telescopic end of the clamping cylinder 811 is fixedly connected to the movable seat 801.

[0042] Both sides of the movable seat 801 are provided with side positioning cylinders 807. The telescopic end of the side positioning cylinder 807 is provided with a side positioning block 809 through the support 808. The top of the side positioning block 809 is provided with a second flange 810 in the horizontal direction. The side positioning blocks 809 on both sides are located on both sides of the slot seat 104.

[0043] Specifically, the end positioning cylinders 802 on both sides drive the positioning seats 803 and end positioning blocks 804 on both sides to move, so that the end positioning blocks 804 at both ends abut against the two ends of the groove seat 104. The side positioning cylinders 807 on both sides drive the side positioning blocks 809 on both sides to move through the support 808, so that the side positioning blocks 809 at both ends abut against the two sides of the groove seat 104. Then, the pressing cylinder 811 drives the movable seat 801 to move downward. The bottom of the first flange 805 and the second flange 810 press against the top of the component to be attached, so as to achieve effective positioning of the component.

[0044] In use, the lifting mechanism 6 on one side drives the pneumatic clamping mechanism 601 to move downwards, passing through the material trough 102 to clamp the component to be bonded on the conveyor belt below, and then lifts it up. The belt conveying mechanism 5 then drives the transmission belt 501 to rotate, and the transmission belt 501 drives the slide 702 to move linearly, so that the clamping blocks 707 on both sides correspond to the two sides of the component to be bonded. At the same time, the clamping block 707 at the other end of the slide 702 corresponds to the two sides of the component that has been bonded in the slot 104. After the positioning component 8 releases the positioning of the bonded component, the lifting cylinder 704 on the other side retracts to drive the clamping block 707 on the other side to move down to correspond to the side of the bonded component. Then, the clamping cylinder 706 on the other side extends to clamp the bonded component, and the extension of the lifting cylinder 704 drives the bonded component to rise.

[0045] At this time, the clamping blocks 707 at both ends of the slide 702 clamp the component to be bonded and the component that has been bonded, respectively. Then, the belt conveyor mechanism 5 drives the transmission belt 501 to rotate, so that the clamping block 707 holding the component to be bonded is reset to the position corresponding to the slot seat 104. At the same time, the component that has been bonded moves to the top of the material trough 102 on the other side, and the lifting mechanism 6 on the other side drives the pneumatic clamping mechanism 601 to move downward to clamp the component that has been bonded. Then, it is placed on the conveyor belt below through the material trough 102. At the same time, the lifting cylinder 704 on the side holding the component to be bonded retracts to place the component to be bonded into the groove in the middle of the slot seat 104. Then, the lifting cylinder 704 and the clamping cylinder 706 are reset.

[0046] Secondly, the end positioning cylinders 802 on both sides extend the end positioning blocks 804 in opposite directions and abut against the two ends of the groove seat 104 respectively. At the same time, the side positioning cylinders 807 on both sides extend the side positioning blocks 809 in opposite directions and abut against the two sides of the groove seat 104 respectively. The contraction of the pressing cylinder 811 drives the movable seat 801 to move downward, so that the bottom of the first flange 805 on the end positioning block 804 abuts against the top surface of the end of the part to be bonded, and the bottom of the second flange 810 on the side positioning block 809 abuts against the top surface of the part to be bonded, thereby achieving the pressing and positioning of the part to be bonded. At the same time, the bottom of the groove seat 104 is elastically squeezed, and the reverse force of the bottom of the groove seat 104 further improves the positioning effect of the part to be bonded, while also achieving buffering to prevent damage to the part to be bonded.

[0047] After positioning, the robotic arm 3 uses the rotary lifting mechanism 301 to move the bonding head 402 to the position corresponding to the antenna on the feeding mechanism 2. The rotary lifting mechanism 301 is used to adjust the position of the bonding head 402 so that it is aligned with the antenna. The robotic arm 3 then transfers the antenna to the top of the part to be bonded. The rotary lifting mechanism 301 is used to adjust the position and angle of the antenna so that it is aligned with the bonding position on the part to be bonded. The position of the auxiliary seat 408 is adjusted by the extension and retraction of the moving cylinder 404 and the adjusting cylinder 412 so that the auxiliary seats 408 on both sides are aligned with the two ends of the antenna. The extension of the electric telescopic rod 409 is used to press the bottom of the auxiliary seat 408 against the two ends of the antenna to prevent the antenna from lifting up and to ensure bonding accuracy. At the same time, the pressure sensor monitors the reverse pressure of the auxiliary seat 408 to prevent excessive pressure from damaging or displacing the antenna.

[0048] After bonding is completed, the positioning component 8 is released to release the positioning. The clamping cylinder 706 drives the clamping block 707 to clamp the two sides of the bonded component. The extension of the lifting cylinder 704 is used to remove the bonded component from the slot 104. Then, the subsequent unloading and loading operations are carried out by the cooperation between the belt conveyor mechanism 5, the lifting mechanism 6 and the conveyor component 7.

[0049] Example 2

[0050] After prolonged use, due to friction and collision, some impurities and particles will fall off and scatter inside the groove 104, thus affecting the flatness of the groove 104 and the bonding accuracy. Therefore, the following improvements are made: The fixing base 708 has a hollow structure and is connected to an external air extraction system through an air extraction pipe. The side of the clamping block 707 is provided with an air inlet 710, which is connected to the fixing base 708 and the strip groove 709.

[0051] Specifically, an external air extraction system is used to generate negative pressure inside the fixed base 708 and at the air inlet 710 to adsorb impurities and particulate matter. The air inlet 710 is connected to the strip groove 709, which acts as a guide groove to increase the effective area of ​​the negative pressure at the air inlet 710.

[0052] The end positioning block 804 has a hollow structure and is connected to an external air supply system through an air supply pipe. The bottom of the first flange 805 has an air guide hole 806 that communicates with the interior of the end positioning block 804.

[0053] Specifically, the external air supply system supplies air to the end positioning block 804 through the air supply pipe and discharges it through the air guide hole 806.

[0054] Before each use, the robotic arm 3 moves the vision sensor 403 above the slot 104 to detect impurities inside the slot 104. When impurities are detected, the belt conveyor 5 drives the slide blocks 702 on both sides via the transmission belt 501, aligning the clamping blocks 707 at the same end of the slide blocks 702 with the middle of the side of the slot 104. The clamping cylinders 706 then extend the clamping blocks 707, aligning the outer walls of the clamping blocks 707 with the inner walls of the slot 104. Next, the lifting cylinders 704 move the clamping blocks 707 downwards, bringing their outer walls into contact with the inner walls of the slot 104. Finally, the lifting cylinders 706 extend the clamping blocks 707. The constricted end slowly extends, causing the clamping blocks 707 on both sides to move in opposite directions and close. At the same time, the external air extraction system uses the air inlet 710 to adsorb impurities and particles in the slot 104. Meanwhile, the end positioning blocks 804 at both ends are positioned above the slot 104. The external air supply system supplies air to the end positioning blocks 804 and discharges it into the slot 104 through the air guide hole 806 at the bottom of the first flange 805. The airflow discharged from the end positioning blocks 804 at both ends causes the impurities and particles located at the ends of the slot 104 to gather towards the center. Combined with the negative pressure at the air inlet 710, the impurities and particles are sucked into the air inlet 710 and discharged to the outside through the air extraction pipe, thus achieving the purpose of cleaning the impurities in the slot 104 and preventing the impurities and particles from scattering everywhere.

[0055] Example 3

[0056] After prolonged use, the operational accuracy of various components and mechanisms will decrease. Furthermore, due to the slight gap between the part to be bonded and the slot 104, the part to be bonded will slightly shift from its original position. Therefore, the following improvements are made: After the component to be bonded is placed in the slot 104, before positioning, the robotic arm 3 moves the auxiliary seat 408 above the component to be bonded, and the rotary lifting mechanism 301 adjusts the position of the bonding head 402 so that the bottom surfaces of the auxiliary seats 408 on both sides correspond to and remain parallel to the top surfaces of the component to be bonded. Then, the bonding head 402 moves downward so that the bottom surfaces of the auxiliary seats 408 are bonded to the two ends or both sides of the top surface of the component to be bonded. The extension of the moving cylinder 404 drives the auxiliary seat 408 to move linearly through the moving seat 405 and the movable plate 406, so that the bottom surface of the auxiliary seat 408 moves linearly along the top surface of the component to be bonded. At this time, the pressure sensor always detects the reverse pressure from the auxiliary seat 408. When the component to be bonded shifts, the bottom of the auxiliary seat 408 will detach from the top surface of the component to be bonded. Therefore, when the pressure sensor detects a pressure value of 0, it can be actively determined that the component to be bonded has shifted.

[0057] When the part to be bonded shifts along the width direction of the groove seat 104, the clamping blocks 707 on both sides are aligned with the two sides of the part to be bonded, and the clamping cylinders 706 on both sides extend to clamp the part to be bonded. Since the central axis between the clamping blocks 707 on both sides coincides with the central axis between the auxiliary seats 408 on both sides when the clamping blocks 707 are in the clamping state, the shift of the part to be bonded along the width direction of the groove seat 104 can be corrected.

[0058] When the part to be bonded shifts along the length of the groove 104, the clamping blocks 707 on both sides clamp the part to be bonded. Then, the belt conveyor mechanism 5 drives the transmission belt 501 to move, so that the conveyor assembly 7 drives the clamped part to be bonded to move linearly along the length of the groove 104. This causes the part to be bonded to move towards the side where the detected pressure value is 0, thus correcting the shift of the part to be bonded along the length of the groove 104.

[0059] After the above correction is completed, the positioning component 8 is used to press and position the parts to be fitted to prevent them from shifting again.

[0060] Example 4

[0061] This invention also discloses a bonding method for flexible circuit board antennas, comprising the following steps: S1. First, the lifting mechanism 6 on one side drives the pneumatic clamping mechanism 601 to clamp the part to be bonded from the bottom conveyor belt of the frame plate 101 and then rises back. The belt conveying mechanism 5 drives the transmission belt 501 to run, which drives the slide 702 and clamping block 707 of the conveying component 7 to move. The clamping block 707 clamps the part to be bonded and transfers it to the top of the slot 104. The lifting cylinder 704 retracts to put the part to be bonded into the groove of the slot 104. Then the lifting cylinder 704 and the clamping cylinder 706 reset. S2. Next, the end positioning cylinder 802 drives the end positioning block 804 to abut against both ends of the groove seat 104, and the side positioning cylinder 807 drives the side positioning block 809 to abut against both sides of the groove seat 104. The pressing cylinder 811 retracts and drives the movable seat 801 to move down, so that the first flange 805 of the end positioning block 804 and the second flange 810 of the side positioning block 809 press against the end and side top surface of the part to be bonded, respectively. The elastic extrusion at the bottom of the groove seat 104 generates a reverse force to assist in positioning, thereby achieving the pressing and positioning of the part to be bonded. S3. Then, the robotic arm 3 drives the bonding head 402 to move to the feeding mechanism 2 through the rotary lifting mechanism 3016, adsorbs the antenna material, and transfers the antenna to the part to be bonded. After the rotary lifting mechanism 3016 adjusts the antenna position and angle, it is bonded to the part to be bonded. The moving cylinder 404 and the adjusting cylinder 412 adjust the position of the auxiliary seat 408 so that it corresponds to the two ends of the antenna. The electric telescopic rod 409 extends to drive the auxiliary seat 408 to push against the two ends of the antenna to prevent it from tilting. The pressure sensor monitors the pressure to prevent damage and ensures bonding accuracy. S4. Finally, the positioning component 8 releases its positioning, the clamping block 707 clamps the bonded component, and the lifting cylinder 704 removes it from the slot 104. The belt conveyor mechanism 5 drives the transmission belt 501, which, together with the conveyor component 7 and the lifting mechanism 6 on the other side, transfers the bonded component to the top of the material trough 102 on the other side. The lifting mechanism 6 on that side clamps the component and places it back onto the conveyor belt through the material trough 102. At the same time, the feeding step is repeated for the next cycle.
