Description

Technical Field

[0001] This invention relates to the field of automotive electronic component assembly equipment technology, specifically a data interface assembly machine for automotive electronic dashboards and its process. Background Technology

[0002] As the core data interface of automotive electronic instrument panel, the assembly quality of the LVDS connector directly determines the stability of data transmission. The connector mainly consists of a base with an integrally molded terminal and a top cover assembly with electromagnetic shielding. The core connection between the two is the engagement of the elastic buckle symmetrically set on the end face of the shielding top cover with the pre-set slot on the edge of the base.

[0003] In existing technologies, the assembly of LVDS connectors mostly adopts a press-fit snap-fit ​​process. After the pre-press-fitting of the wire harness terminals and the base is completed, the shielding cover is snapped on from top to bottom. The snap-fit ​​undergoes elastic deformation under pressure and then snaps into the slot to achieve quick locking.

[0004] While this process simplifies the assembly process and significantly improves the assembly efficiency of the production line, making it suitable for the pace of large-scale production of automotive parts, it has significant technical defects in practical applications: the continuous vibration generated during vehicle operation can easily cause the snap-fit ​​between the clip and the slot to loosen, resulting in a decrease in the connection stability between the shielding cover and the base. This not only affects the electromagnetic shielding effect but also easily causes poor contact of the data interface, leading to problems such as data transmission interruption and distortion, and cannot meet the high reliability requirements of automotive electronic components. Summary of the Invention

[0005] The purpose of this invention is to provide a data interface assembly machine and process for automotive electronic instrument panels, so as to solve the problems mentioned in the background art.

[0006] The objective of this invention can be achieved through the following technical solutions: A data interface assembly machine for an automotive electronic instrument panel, preferably, includes an assembly table, a transfer table disposed on the assembly table, a power mechanism for driving the displacement of the transfer table, a glue leveling linkage mechanism, and a flipping pressing mechanism. The adhesive leveling linkage mechanism includes a dispensing device, a film roll, a ratchet gear for driving the film roll to step and rewind on the assembly table, and an abutting wheel located above the transfer table. The abutting wheel is controlled to press down on the middle section of the film roll to level the adhesive on the bonding surface of the workpiece. The flipping and pressing mechanism includes a first drive plate installed on the assembly table, a cross bar driven to rise and fall by the first drive plate, a feeding suction cup fixedly connected to the bottom of the cross bar, and a Z-shaped transmission slider hinged to the bottom of the cross bar. One end of the Z-shaped transmission slider is slidably embedded in the V-shaped guide rail fixed on the side, so as to guide the feeding suction cup through the trajectory to simultaneously complete the flipping, adsorption and pressing action of the shielding cover. The power mechanism includes a second drive disc that is synchronously linked with the first drive disc. The second drive disc drives the transfer table to reciprocate between the dispensing position and the pressing position via a linkage assembly equipped with a buffer spring.

[0007] Preferably, the adhesive leveling linkage mechanism further includes a first bracket fixed to the top of the assembly table, an L-shaped bracket fixed on the first bracket, a take-up roller and an unwind roller rotatably connected on the L-shaped bracket, and the film roll is wound between the take-up roller and the unwind roller. The winding reel has a rotatable sleeve on its shaft end with a pressure rod, and an abutment wheel is rotatably connected to the end of the pressure rod. An electric actuator is provided on the L-shaped bracket to drive the pressure rod to deflect downward.

[0008] Preferably, the ratchet gear is fixedly sleeved on the end of the take-up reel shaft, and a ratchet rack that meshes with the ratchet gear is fixedly provided on the transfer table; When the transfer table is displaced, the ratchet gear driven by the rack and pinion drives the winding wheel to rotate.

[0009] Preferably, a T-shaped tensioning slide bar is fixedly connected to the L-shaped bracket, the unwinding wheel is slidably connected to the T-shaped tensioning slide bar through the tensioning slider, and a tensioning spring is sleeved on the T-shaped tensioning slide bar and connected between the L-shaped bracket and the tensioning slider.

[0010] Preferably, the flipping pressing mechanism further includes a second bracket fixed on the assembly table, a first drive disc rotatably connected to the second bracket, a cross bar slidably connected to the second bracket and having a follower groove at its horizontal end, and a follower pulley slidably engaged in the follower groove on one side of the first drive disc.

[0011] Preferably, the V-shaped guide rail is fixedly connected to one end of the second bracket, and is used to forcefully guide the feeding suction cup to perform a flipping action synchronously during the lifting and lowering of the cross bar using the V-shaped trajectory.

[0012] Preferably, the linkage assembly includes a first traction rod eccentrically hinged to the bottom of the second drive disc and a second traction rod hinged to the end of the first traction rod; One end of the second traction rod moves through the transfer platform, and a buffer spring is sleeved on the end of the second traction rod. The second traction rod is elastically connected to the transfer platform through the buffer spring.

[0013] Preferably, the power mechanism further includes a power motor mounted on the second bracket, which drives the second drive disk to rotate through a drive gear at its output end and a driven gear connected to the shaft end of the second drive disk.

[0014] Preferably, the shaft end of the second drive disk is fixedly provided with a first bevel gear, and the shaft end of the first drive disk is fixedly provided with a second bevel gear that meshes with the first bevel gear; A positioning block is fixedly connected to the inner side of the first bracket.

[0015] An assembly process for a data interface of an automotive electronic instrument panel includes the following steps: Step 1: Loading and positioning. The robotic arm transfers the integrated terminal base into the preset groove of the transfer table to complete the positioning of the terminal base. The power mechanism is started to drive the transfer table to move towards the dispensing position. Step 2: Dispensing and leveling the adhesive. When the transfer stage moves to the dispensing position, the dispensing device applies adhesive along the bonding surface of the integrated terminal base and the shielding cover. Then the transfer stage continues to move, the electric push rod is activated, driving the downward pressure rod to deflect downward, causing the contact wheel to press down on the middle section of the film roll, so that the film is bonded to the bonding surface and the applied adhesive is leveled. At the same time, the displacement of the transfer stage causes the ratchet rack and ratchet gear to mesh, driving the winding wheel to rotate, and step-by-step winding of the used film. The tension spring extends and retracts synchronously to maintain the tension of the film roll. Step 3: Flipping and Pressing. The power mechanism drives the transfer table to the pressing position, and the transfer table abuts against the positioning block to achieve precise positioning. At this time, the first drive plate and the second drive plate move synchronously. The first drive plate drives the follower pulley to slide in the follower slide groove, driving the cross rod to rise and fall. At the same time, the Z-shaped transmission slider slides along the V-shaped trajectory of the V-shaped guide slide rail, guiding the feeding suction cup to move upward and flip. After the shielding cover is picked up by the feeding mechanism, it flips and moves downward to press the shielding cover onto the top of the integrated terminal base, so that the elastic buckle of the shielding cover engages with the base slot. During the pressing process, the second traction rod continues to move, squeezing the buffer spring to generate elastic deformation, compensating for the stroke difference between the positioning of the transfer table and the pressing of the feeding suction cup, ensuring accurate pressing. Step 4: Unloading and Cycling. After pressing is completed, the electric push rod resets, driving the contact wheel to move upward and detach from the workpiece; the power mechanism drives the transfer table to reset from the pressing position, and at the same time the robot transfers the assembled workpiece to the unloading conveyor belt; then another robot transfers the new integrated terminal base into the groove of the transfer table, entering the next assembly cycle, realizing continuous automated assembly.

[0016] The beneficial effects of this invention are: 1. This invention uses a dispensing device to precisely dispense adhesive along the bonding surface, and works in conjunction with an adhesive leveling linkage mechanism consisting of an electric push rod, a contact wheel, and a film roll to flatten the adhesive layer and ensure uniform coating. At the same time, the film's isolating effect prevents the adhesive from sticking to equipment parts. The unidirectional transmission of the ratchet and ratchet rack enables the film to be wound in a step-by-step manner, ensuring consistent smoothing results for each operation. Under the pressure of the pressing force, the adhesive penetrates into the bonding gap between the buckle and the slot, forming a tight composite fixation with the snap-fit ​​structure, which greatly improves the connection stability and vibration resistance of the LVDS connector.

[0017] 2. This invention uses a power motor to drive the first drive plate and the second drive plate to rotate synchronously through gear and bevel gear transmission. This not only realizes the reciprocating transfer of the transfer table, but also drives the feeding suction cup to complete the flipping suction and pressing action. At the same time, combined with the precise positioning of the transfer table by the positioning block and the elastic compensation of the pressing stroke difference by the buffer spring, it ensures the alignment of the pressing of the shielding cover and the terminal base, avoiding problems such as buckle deformation and incomplete engagement.

[0018] 3. This invention achieves automated loading and unloading through the cooperation of a robotic arm and a conveyor belt. The transfer of the transfer table and the reset actions of each mechanism are all synchronously driven by a power source, requiring no manual intervention. Furthermore, the tension spring of the glue leveling linkage mechanism can always maintain the tension of the film, and the electric push rod can realize the rapid lifting and resetting of the contact wheel. The unidirectional transmission of the ratchet and ratchet rack prevents the take-up wheel from turning over. The operation of each component is smooth and the linkage is precise, which not only reduces the labor intensity and error rate of manual operation, but also ensures the consistency of product quality during continuous assembly.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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] A data interface assembly machine and its process for automotive electronic instrument panels are disclosed. The core technical solution of this assembly machine and process is to address the following issues through the coordinated operation of a glue leveling linkage mechanism, a flipping and pressing trajectory guiding mechanism, a power synchronous drive mechanism, and a buffer positioning compensation mechanism. These issues include the susceptibility to loosening due to vehicle vibration in traditional LVDS connector assembly using pure snap-fit ​​connections, uneven glue application and equipment adhesion during glue bonding reinforcement, misalignment due to poor coordination of multiple power source drive assembly mechanisms, and low automation and difficulty in balancing assembly accuracy and efficiency in traditional assembly equipment. This assembly machine and its process belong to the field of automotive electronic component assembly equipment technology. It is specifically designed to achieve dual fixation through pure mechanical linkage, including glue bonding and snap-fit, synchronous operation of various assembly processes, integrated operation of glue application and leveling, and fully automated assembly of LVDS connectors. This results in stable connection of the automotive electronic instrument panel data interface under vehicle vibration conditions, high precision and efficiency in assembly operations, and adaptability for large-scale production of automotive electronic components and reliable data transmission of the data interface.

[0023] like Figures 1-9 As shown, it includes an assembly table 1, a transfer table 2 set on the assembly table 1, a power mechanism for driving the displacement of the transfer table 2, a glue leveling linkage mechanism, and a flipping pressing mechanism. The glue leveling linkage mechanism includes a dispensing device 6, a film roll 10, a ratchet gear 14 for driving the film roll 10 to step and rewind, and an abutting wheel 12 located above the transfer table 2. The abutting wheel 12 is controlled to press down on the middle section of the film roll 10 to level the glue on the bonding surface of the workpiece. The flipping and pressing mechanism includes a first drive plate 19 mounted on the assembly table 1, a cross bar 20 driven and lifted by the first drive plate 19, a feeding suction cup 5 fixedly connected to the bottom of the cross bar 20, and a Z-shaped transmission slider 23 hinged to the bottom of the cross bar 20. One end of the Z-shaped transmission slider 23 is slidably embedded in the V-shaped guide rail 24 fixed on the side, so as to guide the feeding suction cup 5 through the trajectory to simultaneously complete the flipping, adsorption and pressing action of the shielding cover. The power mechanism includes a second drive disc 25 that is synchronously linked with the first drive disc 19. The second drive disc 25 drives the transfer table 2 to reciprocate between the dispensing position and the pressing position through a linkage assembly equipped with a buffer spring 33. The glue leveling linkage mechanism also includes a first bracket 3 fixed on the top of the assembly table 1. An L-shaped bracket 7 is fixed on the first bracket 3. A take-up wheel 8 and an unwind wheel 9 are rotatably connected on the L-shaped bracket 7. The take-up wheel 8 is rotatably connected through a first damping bearing embedded in the L-shaped bracket 7. The film roll 10 is wound between the take-up wheel 8 and the unwind wheel 9. The shaft end of the winding reel 8 is rotatably fitted with a pressure rod 11, and the contact wheel 12 is rotatably connected to the end of the pressure rod 11. The L-shaped bracket 7 is provided with an electric push rod 13 that drives the pressure rod 11 to deflect downward. Furthermore, the ratchet 14 is fixedly sleeved on the shaft end of the winding wheel 8, and a ratchet rack 15 that meshes with the ratchet 14 is fixedly installed on the transfer table 2; When the transfer table 2 is displaced, it drives the ratchet gear 14 through the ratchet rack 15 to rotate the winding wheel 8. Furthermore, a T-shaped tensioning slide bar 16 is fixedly connected to the L-shaped bracket 7, and the unwinding wheel 9 is slidably connected to the T-shaped tensioning slide bar 16 through the tensioning slider 17. A tensioning spring 18 is sleeved on the T-shaped tensioning slide bar 16 and connected between the L-shaped bracket 7 and the tensioning slider 17. The unwinding wheel 9 is rotatably connected through a second damping bearing embedded in the tensioning slider 17. Furthermore, the flipping pressing mechanism also includes a second bracket 4 fixed on the assembly table 1, a first drive disk 19 rotatably connected to the second bracket 4, a cross rod 20 slidably connected to the second bracket 4 and a follower groove 21 opened at its horizontal end, and a follower pulley 22 slidably engaged in the follower groove 21 on one side of the first drive disk 19. Furthermore, the V-shaped guide rail 24 is fixedly connected to one end of the second bracket 4, and is used to forcefully guide the feeding suction cup 5 to perform a flipping action synchronously during the lifting and lowering of the cross bar 20 using the V-shaped trajectory. Furthermore, the linkage assembly includes a first traction rod 28 eccentrically hinged to the bottom of the second drive disc 25 and a second traction rod 29 hinged to the end of the first traction rod 28; One end of the second traction rod 29 moves through the transfer platform 2, and the buffer spring 33 is sleeved on the end of the second traction rod 29. The second traction rod 29 is elastically connected to the transfer platform 2 through the buffer spring 33. Furthermore, the power mechanism also includes a power motor 30 mounted on the second bracket 4. The power motor 30 drives the second drive disk 25 to rotate through the drive gear 31 at its output end and the driven gear 32 connected to the shaft end of the second drive disk 25. Furthermore, a first bevel gear 26 is fixedly provided on the shaft end of the second drive disk 25, and a second bevel gear 27 that meshes with the first bevel gear 26 is fixedly provided on the shaft end of the first drive disk 19. A positioning block 34 is fixedly connected to the inner side of the first bracket 3.

[0024] In use, firstly, before the assembly operation starts, the feeding conveyor belt next to the assembly table 1 transports the integrated terminal base. The robotic arms on the two first supports 3 complete the precise picking and unloading actions. After the feeding robotic arm picks up the terminal base, it is smoothly transferred to the preset groove of the transfer table 2 between the two first supports 3. The limiting structure of the groove cooperates with the precise unloading of the robotic arm to make the terminal base achieve a firm initial positioning. Then, the power motor 30 at the second bracket 4 end is started. The driving gear 31 at its output end meshes with the driven gear 32 at the shaft end of the second drive disk 25, driving the second drive disk 25 to rotate. At the same time, the first bevel gear 26 at the shaft end of the second drive disk 25 meshes synchronously with the second bevel gear 27 at the shaft end of the first drive disk 19, thereby driving the first drive disk 19 and the second drive disk 25 to rotate at the same speed. This single power source transmission method can achieve synchronous and stable power transmission, so that the subsequent transfer action of the drive transfer table 2 and the flipping and pressing action of the drive loading suction cup 5 keep the rhythm consistent. Simultaneously, the rotation of the second drive disc 25 causes the first traction rod 28 at its bottom to swing, which in turn pulls the second traction rod 29 to move the transfer platform 2 to the left along the first bracket 3 towards the second bracket 4. During the transfer, the transfer platform 2 causes the terminal base to pass under the dispensing device 6 at the top of the first bracket 3. At this time, the dispensing device 6 is precisely activated, dispensing adhesive along the mating surface of the terminal base and the snap-fit ​​connection end of the shielding cover. The dispensing position of the dispensing device 6 precisely corresponds to the mating surface, which can make the adhesive layer evenly cover the mating area of ​​the snap-fit ​​connection. Next, as the transfer table 2 continues to move to the left, bringing the terminal base below the contact wheel 12, the electric push rod 13 on the side of the L-shaped bracket 7 is activated and pushes the pressing rod 11 to deflect downward around the hinge axis. The contact wheel 12 at the end of the pressing rod 11 then presses down, tightly adhering the middle section of the film roll 10 on the unwinding roller 9 to the adhesive bonding surface of the terminal base. The downward pressing force of the contact wheel 12 can completely smooth the adhesive layer on the bonding surface, turning the originally dotted and linear adhesive layer into a uniform thin adhesive layer, avoiding local accumulation of adhesive layer that may affect subsequent snap-fitting. At the same time, the isolation effect of the film can effectively prevent the adhesive from directly adhering to the surface of the contact wheel 12, preventing the contact wheel 12 from becoming sticky and reducing the subsequent smoothing effect, thus ensuring the continuity of the adhesive smoothing operation. As the contact wheel 12 presses down and the transfer table 2 moves to the left, the unwinding wheel 9 moves along the T-shaped tensioning slide bar 16 with the pulling of the film, compressing the tension spring 18 and causing it to deform. The elastic rebound force of the tension spring 18 can always provide a stable tension force for the film roll 10, keeping the film straight and preventing the film from wrinkling or loosening and affecting the glue smoothing effect. At the same time, the ratchet rack 15 at the top of the transfer table 2 meshes with the ratchet gear 14 at the shaft end of the take-up wheel 8, driving the take-up wheel 8 to rotate and rewind the used film section, so that the unused clean film is always aligned with the pressing position of the contact wheel 12, ensuring that the effect of each glue smoothing operation is consistent. In addition, the ball bearing at the shaft end of the take-up wheel 8 can make the pressing rod 11 deflect only with the electric push rod 13 and not rotate with the take-up wheel 8, avoiding interference between the two movements and causing damage to the components. After the adhesive is smoothed, the transfer table 2 continues to move to the left until its end abuts against the positioning block 34 on the inner side of the first bracket 3. The mechanical limiting effect of the positioning block 34 ensures that the transfer table 2 stops precisely at the pressing position, completely eliminating the positional deviation of the transfer table 2 during the transfer process. This ensures that the center of the terminal base is precisely aligned with the pressing center of the subsequent feeding suction cup 5, preventing misalignment between the shielding cover and the terminal base due to positional deviation of the transfer table 2, and ensuring the alignment accuracy of the subsequent pressing process. At this time, the second drive disk 25 has not completed half a rotation, and the transfer table 2 completes the positioning before the feeding suction cup 5, reserving operating space for the stroke difference compensation of the subsequent pressing. Throughout the entire process of the transfer table 2 moving left to feed material, the first drive disk 19 rotates synchronously with the second drive disk 25. The follower pulley 22 at its side slides within the follower groove 21 of the cross rod 20, pushing the cross rod 20 up and down along the second bracket 4. The Z-shaped transmission slider 23 at the bottom of the cross rod 20 slides along the V-shaped guide rail 24, driving the feeding suction cup 5 to complete the flipping action. When the cross rod 20 moves upward, the feeding suction cup 5 flips upward and precisely aligns with the bottom opening of the top feeding box of the second bracket 4, achieving stable adsorption of the shielding cover and ensuring that the shielding cover does not fall off or shift during the flipping process. After the transfer table 2 completes the pressing and positioning, the cross rod 20 moves downward, and the feeding suction cup 5 flips downward, precisely aligning the shielding cover with the top of the terminal base. When the feeding suction cup 5 presses downwards, the transfer table 2 is limited by the positioning block 34 and cannot move. The second traction rod 29 moves forward with the continued rotation of the second drive disc 25, squeezing the buffer spring 33 at its end to produce elastic deformation. This deformation can effectively compensate for the stroke difference between the positioning of the transfer table 2 and the pressing of the feeding suction cup 5, so that the feeding suction cup 5 can press the shielding cover smoothly and accurately onto the top of the terminal base, avoiding incomplete pressing due to stroke difference. During the pressing process, the elastic buckle deforms under pressure and then snaps into the slot of the terminal base. The glue penetrates into the gap between the buckle and the slot under the action of pressing force. The glue layer and the snap-fit ​​structure cooperate to form a double fixation, making the connection between the shielding cover and the terminal base tighter and fundamentally improving the vibration resistance of the connection structure. After the shielding cover and terminal base are pressed together, the second drive disc 25 continues to rotate half a turn, driving the transfer table 2 to move to the right and reset, moving it out of the pressing range of the feeding suction cup 5, via the first traction rod 28 and the second traction rod 29. During this process, the electric push rod 13 reverses and drives the lower pressure rod 11 to deflect upward, causing the contact wheel 12 to move upward and completely disengage from the workpiece, preventing the contact wheel 12 from scraping or interfering with the workpiece during the movement of the transfer table 2. The tension spring 18 releases its elastic potential energy, pushing the tension slider 17 to reset along the T-shaped tension slide rod 16, driving the unwinding wheel 9 to return to its position, restoring the film roll 10 to its initial tension state, preparing for the next glue smoothing operation. The rightward movement of the transfer table 2 disengages the ratchet rack 15 from the ratchet gear 14, preventing the take-up wheel 8 from reversing, and then the contact ring in the middle of the second traction rod 29 pushes the transfer table 2 to move smoothly to the right. When the transfer table 2 moves to the right to the side of the initial workstation, the unloading robot smoothly picks up the assembled LVDS connector workpiece from the groove of the transfer table 2 and transfers it to the unloading conveyor belt, which then transports the workpiece to the next process. At the same time, the loading robot moves synchronously to pick up the new integrated terminal base on the loading conveyor belt and transfer it to the empty groove of the transfer table 2, completing a new round of loading and positioning.

[0025] An assembly process for a data interface of an automotive electronic instrument panel includes the following steps: Step 1: Loading and positioning. The robotic arm transfers the integrated terminal base into the preset groove of the transfer table 2 to complete the positioning of the terminal base. The power mechanism is started to drive the transfer table 2 to move towards the dispensing position. Step 2: Dispensing and leveling the adhesive. When the transfer table 2 moves to the dispensing position, the dispensing device 6 applies adhesive along the bonding surface of the integrated terminal base and the shielding cover. Then, the transfer table 2 continues to move, the electric push rod 13 is activated, driving the downward pressure rod 11 to deflect downward, driving the contact wheel 12 to press down the middle section of the film roll 10, so that the film is bonded to the bonding surface and the applied adhesive is leveled. At the same time, the displacement of the transfer table 2 causes the ratchet rack 15 to mesh with the ratchet gear 14, driving the winding wheel 8 to rotate, and step-by-step winding of the used film. The tension spring 18 extends and retracts synchronously to maintain the tension of the film roll 10. Step 3: Flipping and pressing. The power mechanism drives the transfer table 2 to move to the pressing position. The transfer table 2 abuts against the positioning block 34 to achieve precise positioning. At this time, the first drive disk 19 and the second drive disk 25 move in sync. The first drive disk 19 drives the follower pulley 22 to slide in the follower slide groove 21, driving the cross rod 20 to rise and fall. At the same time, the Z-shaped transmission slider 23 slides along the V-shaped trajectory of the V-shaped guide slide rail 24, guiding the feeding suction cup 5 to move upward and flip. After the shielding cover is adsorbed from the feeding mechanism, it flips and moves downward to press the shielding cover onto the top of the integrated terminal base, so that the elastic buckle of the shielding cover engages with the base slot. During the pressing process, the second traction rod 29 continues to move, compressing the buffer spring 33 to generate elastic deformation, compensating for the stroke difference between the positioning of the transfer table 2 and the pressing of the feeding suction cup 5, ensuring accurate pressing. Step 4: Unloading and Cycling. After pressing is completed, the electric push rod 13 is reset, driving the contact wheel 12 to move upward and detach from the workpiece; the power mechanism drives the transfer table 2 to reset from the pressing position, and at the same time the robot transfers the assembled workpiece to the unloading conveyor belt; then another robot transfers the new integrated terminal base into the groove of the transfer table 2, and enters the next assembly cycle to achieve continuous automated assembly.

[0026] The working principle of the data interface assembly machine and process for an automotive electronic instrument panel provided by this invention is as follows: First, two conveyor belts symmetrically arranged on the top of the assembly table 1 are responsible for feeding the integrated terminal base and unloading the assembled finished product, respectively. The robotic arms on the two first supports 3 work together: the feeding robotic arm accurately grabs the integrated terminal base on the feeding conveyor belt and transfers it to the preset groove of the transfer table 2 that slides between the two first supports 3, thus completing the positioning and limiting of the terminal base. At this time, the transfer table 2 is in the initial working position, waiting for the power to drive the transfer. Then, the power motor 30 fixed at one end of the second bracket 4 is started. The driving gear 31 at the output end of the power motor 30 meshes with the driven gear 32 at the shaft end of the second drive disk 25, driving the second drive disk 25 to rotate. The first bevel gear 26 at the shaft end of the second drive disk 25 rotates synchronously with it and meshes with the second bevel gear 27 at the shaft end of the first drive disk 19, thereby driving the first drive disk 19 to rotate synchronously, realizing the power transmission from a single power source to two drive disks. The subsequent reciprocating transfer of the transfer table 2 and the flipping and pressing action of the loading suction cup 5 are all completed by the two synchronously rotating drive disks. Next, when the second drive disc 25 rotates, the first traction rod 28, which is eccentrically hinged at its bottom, swings with the disc, pulling the second traction rod 29, which is hinged at its end. The second traction rod 29 pulls the transfer table 2 to move to the left along the first bracket 3 towards the second bracket 4. During the transfer, the transfer table 2 first drives the integrated terminal base to pass under the dispensing device 6 at the top of the first bracket 3. At this time, the dispensing device 6 is activated and accurately outputs glue along the mating surface of the integrated terminal base and the buckle connection end of the shielding cover, so as to coat the glue layer for subsequent reinforcement connection. The transfer table 2 continues to move to the left to the bottom of the contact wheel 12. Subsequently, when the transfer table 2 moves the terminal base to below the contact wheel 12, the electric push rod 13 hinged on one side of the L-shaped bracket 7 is activated, pushing the pressure rod 11, which is rotatably sleeved with the shaft end of the take-up wheel 8 through a ball bearing, to deflect downward around the hinge shaft. The contact wheel 12 at the end of the pressure rod 11 presses down accordingly, tightly adhering the middle section of the film roll 10 sleeved on the unwinding wheel 9 to the adhesive bonding surface of the terminal base. The pressing action of the contact wheel 12 is used to push the adhesive flat, ensuring that the adhesive layer is coated evenly. During the pressing process, the film is pulled, and the unwinding wheel 9 drives the tensioning slider 17 to move along the T-shaped tensioning slide bar 16, compressing the tensioning spring 18 to produce a contraction deformation and maintain the tension of the film. At the same time, the transfer table 2 moves to the left, and the ratchet rack 15 at its top meshes with the ratchet gear 14 at the shaft end of the take-up wheel 8. The tooth surface of the ratchet rack 15 pushes the pawl on the ratchet gear 14 to flip, thereby realizing transmission and driving the take-up wheel 8 to rotate. This allows for step-by-step winding of the used film segments, avoiding the reuse of adhesive. Furthermore, the ball bearing at the shaft end of the take-up wheel 8 ensures that the pressing rod 11 only deflects with the electric push rod 13 and does not rotate synchronously with the take-up wheel 8. Next, after the adhesive is smoothed out, the transfer table 2 continues to move to the left until one end of it abuts against the positioning block 34 inside the first bracket 3, achieving precise positioning of the pressing position and preventing misalignment between the shielding cover and the terminal base during subsequent pressing. At this time, the second drive plate 25 is not yet fully rotated, while the transfer table 2 is in place. However, the first drive plate 19 and the second drive plate 25 rotate synchronously, and the feeding suction cup 5 has not yet completed the pressing action, reserving stroke for subsequent buffer compensation. As the transfer table 2 moves to the left, the first drive disk 19 rotates synchronously. The follower pulley 22, eccentrically connected to one side of the drive disk, slides within the follower groove 21 at the horizontal end of the crossbar 20, pushing the crossbar 20 up and down along the second support 4. One end of the Z-shaped transmission slider 23, hinged to the bottom of the crossbar 20, is fixed to the loading suction cup 5, while the other end slides into the V-shaped guide rail 24 of the second support 4. When the crossbar 20 rises and falls, the Z-shaped transmission slider 23 slides along the trajectory of the V-shaped guide rail 24, causing the loading suction cup 5 to complete its flipping action. When the cross bar 20 moves upward, the feeding suction cup 5 flips upward and adsorbs a shielding cover from the bottom opening of the feeding box at the top of the second bracket 4. After the transfer table 2 is positioned, the first drive plate 19 continues to drive the cross bar 20 to move down, and the feeding suction cup 5 flips down to accurately align the shielding cover with the top of the terminal base and begin to press down. During the pressing process, the transfer table 2 is limited by the positioning block 34 and cannot move. The second traction rod 29 continues to move with the second drive disc 25, compressing the buffer spring 33 sleeved at its end to generate contraction deformation, compensating for the stroke difference between the positioning of the transfer table 2 and the pressing of the feeding suction cup 5, ensuring that the shielding cover is completely pressed against the top of the terminal base. The elastic buckle of the shielding cover undergoes elastic deformation under pressure. When the buckle moves to the position of the base slot, it quickly snaps into place by relying on the elastic restoring force to achieve the snap-fit. Under the action of the pressing force, the glue penetrates into the fitting gap between the buckle and the slot, forming a double fixation with the snap-fit, and strengthening the connection stability. After pressing is completed, the second drive disc 25 continues to rotate half a turn, driving the transfer table 2 to move to the right via the first traction rod 28 and the second traction rod 29, disengaging it from below the feeding suction cup 5; during this process: When the electric actuator 13 is activated and reset, it drives the lower pressure rod 11 to deflect upward around the hinge axis, and the contact wheel 12 moves upward and separates from the workpiece to avoid interference with the material feeding. The tension spring 18 releases its elastic potential energy, pushing the tension slider 17 to reset along the T-shaped tension slide bar 16, which in turn drives the unwinding wheel 9 to return to its original position, maintaining the tension of the film roll 10. As the transfer table 2 moves to the right, the ratchet rack 15 separates from the ratchet gear 14, the pawl disengages from the tooth surface under the action of gravity, and the winding wheel 8 stops rotating. The buffer spring 33 first rebounds to its original position, and then the contact ring in the middle section of the second traction rod 29, in conjunction with the second traction rod 29, pushes the transfer table 2 to move smoothly to the right. When transfer table 2 moves to the right to the side of the initial workstation, the unloading robot picks up the assembled LVDS connector workpiece from the groove of transfer table 2 and transfers it to the unloading conveyor belt, which then transports the workpiece to the next process. At the same time, the loading robot transfers the new integrated terminal base from the loading conveyor belt to the empty groove of transfer table 2, completing the cycle loading.

A data interface assembly process for an automotive electronic instrument panel, employing the data interface assembly machine for an automotive electronic instrument panel as described in claim 9, characterized in that: Includes the following steps: Step 1: Loading and positioning. The integrated terminal base is transferred to the preset groove of the transfer table (2) by the robot arm to complete the positioning of the terminal base. The power mechanism is started to drive the transfer table (2) to move towards the dispensing position. Step 2: Dispensing and leveling the adhesive. When the transfer table (2) moves to the dispensing position, the dispensing device (6) applies adhesive along the bonding surface of the integrated terminal base and the shielding cover. Then the transfer table (2) continues to move, the electric push rod (13) is activated, driving the pressure rod (11) to deflect downward, driving the contact wheel (12) to press down on the middle section of the film roll (10), so that the film is bonded to the bonding surface and the applied adhesive is leveled. At the same time, the displacement of the transfer table (2) drives the ratchet rack (15) to mesh with the ratchet gear (14), driving the winding wheel (8) to rotate, and step-by-step winding of the used film. The tension spring (18) extends and retracts synchronously to maintain the tension of the film roll (10). Step 3: Flipping and pressing.

At the same time, the Z-shaped transmission slider (23) slides along the V-shaped trajectory of the V-shaped guide slide rail (24) to guide the feeding suction cup (5) to move up and flip. After the shielding cover is adsorbed from the feeding mechanism, it flips down and presses the shielding cover onto the top of the integrated terminal base, so that the elastic buckle of the shielding cover is engaged with the base slot.
