Technical Field

[0001] This invention relates to the field of edge banding technology for the inner and outer panels of a car body-in-white door cover, and specifically to a car door cover pressing module. Background Technology

[0002] Currently, in major automotive body-in-white door and hood production lines, specialized lamination technology has been widely used in the edge-sealing connection of inner and outer panels of body-in-white doors and hoods. It offers advantages such as stable process and high production speed, and is mainly applied to components such as left and right front doors, left and right rear doors, front hoods, and rear hoods. However, existing specialized lamination equipment for doors and hoods suffers from problems such as high cost and difficulty in technological improvement. The lamination unit is the core component of the specialized lamination machine. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a novel automotive door cover pressing module with high stability, high precision, high efficiency, and excellent product molding quality.

[0004] The technical solution adopted in this invention is as follows:

[0005] A car door cover pressing module is provided for use on a pressing machine, including a fixed frame, a horizontal sliding group, a vertical sliding group, and an insert assembly; the fixed frame is fixed in position;

[0006] The vertical sliding assembly includes a vertical movable frame, a motor, a belt drive mechanism, and a lead screw and nut pair. The vertical movable frame is slidably connected to the fixed frame. The motor is fixed on the vertical movable frame. The output end of the motor is connected to the lead screw and nut pair through the belt drive mechanism. The vertical relative movement of the vertical movable frame with respect to the fixed frame is achieved by driving the lead screw and nut pair.

[0007] The horizontal sliding assembly includes a block component mounting base, a guide groove base, a sliding plate, and a drive cylinder. The drive cylinder is fixed on the vertical movable frame, and its output end is connected to the sliding plate. The guide groove base is fixed to the top of the vertical sliding assembly. The sliding plate is horizontally slidable within the guide groove base, and the block component mounting base is fixed on the sliding plate. The drive cylinder drives the block component mounting base to move horizontally.

[0008] The insert assembly is fixed on the insert assembly mounting base, and the insert assembly includes a final press-fit insert and a pre-press-fit insert located below it.

[0009] Furthermore, the horizontal sliding group drives the insert assembly to reciprocate horizontally between the working position and the exit position; the vertical sliding group drives the insert assembly to move up and down, passing through the pre-pressing preparation position, the pre-pressing position, the final pressing preparation position, and the final pressing position from top to bottom.

[0010] Furthermore, the horizontal sliding assembly also includes a working position stop block assembly and an exit position stop block assembly, which are used to mechanically protect and limit the insert assembly in the working position and exit position, respectively.

[0011] Furthermore, the vertical sliding assembly also includes a pre-pressing stop block assembly and a final pressing stop block assembly, which are used to mechanically protect and limit the insert assembly in the pre-pressing position and the final pressing position, respectively.

[0012] Furthermore, the pre-compression stop block group includes a first pre-compression stop block and a second pre-compression stop block, and the final compression stop block group includes a first final compression stop block and a second final compression stop block. The first pre-compression stop block and the second pre-compression stop block are respectively provided with a stop end and a clearance part.

[0013] In the pre-pressing position, the stopping ends of the first pre-pressing stop block and the second pre-pressing stop block contact each other to form a protective limit, and there is a gap between the first final pressing stop block and the second final pressing stop block in the vertical direction.

[0014] After pre-pressing is completed, the insert assembly first moves horizontally to the exit position. At this time, the stop end of the first pre-pressing stop block and the stop end of the second pre-pressing stop block have a gap in the horizontal direction. Then, the insert assembly moves downward to the final pressing preparation position, and then moves horizontally to the working position. At this time, the stop ends of the first pre-pressing stop block and the stop ends of the second pre-pressing stop block are respectively embedded in each other's clearance parts, so that the insert assembly can move downward to the final pressing position. When moving to the final pressing position, the first final pressing stop block and the second final pressing stop block contact each other to form a protective limit.

[0015] Furthermore, the motor is a servo variable frequency motor equipped with an absolute encoder.

[0016] Furthermore, the sliding plate cooperates with the guide groove in the guide groove seat, allowing it to slide horizontally, and a self-lubricating friction plate is installed in the guide groove.

[0017] Furthermore, a vertically extending guide rail is fixed on the vertical movable frame, and a slider is fixed on the fixed frame. The slider cooperates with the guide rail to allow the vertical movable frame to slide relative to the fixed frame in the vertical direction.

[0018] Furthermore, a transmission box is provided at the lower part of the vertical movable frame, and the belt drive mechanism is located inside the transmission box. The belt drive mechanism includes a driving wheel, a belt, and a driven wheel. The driving wheel is fixed on the output end of the motor, and the driven wheel is fixed on the lower end of the lead screw of the lead screw nut pair. The driving wheel and the driven wheel are connected by the belt drive.

[0019] Furthermore, the lead screw of the lead screw and nut pair is rotatably connected to the vertical movable frame and its axial position is fixed, while the nut is fixed on the fixed frame.

[0020] Furthermore, the vertical movable frame and the fixed frame are respectively equipped with corresponding travel rulers and pointers.

[0021] Furthermore, multiple automotive door cover pressing modules are combined to form a pressing unit of the pressing machine, with each automotive door cover pressing module having a different installation angle.

[0022] Furthermore, the pressing unit is mounted on the base frame of the pressing machine.

[0023] Furthermore, the pressing process is as follows:

[0024] After starting the operation, the insert assembly moves upward from its initial position to its highest point, which is the pre-pressing preparation position and the retraction position. The drive cylinder actuates, and the insert assembly moves horizontally to the working position. The motor actuates, and the insert assembly moves downward to the pre-pressing position, where the pre-pressing insert pre-presses the outer plate of the part. After pre-pressing is completed, the motor actuates, and the insert assembly moves upward to the pre-pressing preparation position, disengaging from the part. The drive cylinder returns, and the insert assembly moves horizontally to the retraction position. The motor actuates, and the insert assembly moves downward to the final pressing preparation position. The drive cylinder actuates, and the insert assembly moves horizontally to the working position. The motor actuates, and the insert assembly moves downward to the final pressing position, where the final pressing insert performs final pressing on the outer plate of the part. After final pressing is completed, the motor actuates, and the insert assembly moves upward to the final pressing preparation position, disengaging from the part. The drive cylinder returns, and the insert assembly moves away from the part back to its initial position. This completes one pressing cycle.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The pressing process of this pressing module is achieved by a motor driving a gear belt and then a lead screw and nut pair. It has the characteristics of simple structure, stable and reliable transmission, strong buffering performance and strong vibration absorption performance, which can effectively reduce the impact of the force generated during the pressing process on the equipment.

[0027] 2. The pressing unit adopts a modular design, reducing the types of spare parts;

[0028] 3. The modules in the pressing unit can be adjusted at their installation angles to accommodate complex part shapes;

[0029] 4. The drive components use standard, non-customized parts, ensuring high versatility;

[0030] 5. The horizontal sliding of the insert is directly driven by a cylinder, which is simple and straightforward in structure and fast in speed;

[0031] 6. The motor is a servo motor equipped with an absolute encoder, which can accurately control the running position to ensure repeatability and ensure that the motor position zero point is not lost after power failure and restart. This is achieved through servo frequency conversion motor control, which is simple to program and easy to adjust. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, unless otherwise explicitly specified.

[0042] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] like Figure 1 As shown, this invention provides an automotive door cover pressing module for use on a pressing machine, comprising a fixed frame 1, a vertical sliding assembly 2, a horizontal sliding assembly 3, and an insert assembly 4. The fixed frame 1 is mounted on the base frame of the pressing machine and remains in a fixed position during the pressing process.

[0045] like Figures 2-4 As shown, the vertical sliding assembly 2 includes a vertical movable frame 26, a motor 28, a belt drive mechanism, and a lead screw and nut pair. The vertical movable frame 26 is slidably connected to the fixed frame 1. The motor 28 is fixed to the vertical movable frame 26, and the output end of the motor 28 is connected to the lead screw and nut pair through the belt drive mechanism. The relative movement of the vertical movable frame 26 with respect to the fixed frame 1 in the vertical direction is achieved by driving the lead screw and nut pair.

[0046] In one specific embodiment, a transmission box 24 is provided at the lower part of the vertical movable frame 26. A belt drive mechanism is located inside the transmission box 24. The belt drive mechanism includes a driving pulley 241, a belt 242, and a driven pulley 243. The driving pulley 241 is fixed to the output end of the motor 28, and the driven pulley 243 is fixed to the lower end of the lead screw 23 of the lead screw and nut pair. The driving pulley 241 and the driven pulley 243 are connected by the belt 242. The lead screw 23 of the lead screw and nut pair is rotatably connected to the vertical movable frame 26 and its axial position is fixed. The nut 11 is fixed to the fixed frame 1. The belt drive mechanism can effectively buffer the impact during operation, providing stable and reliable transmission, strong buffering performance, and strong vibration absorption performance, making the operation more gentle. Combined with the structural form of the lead screw and nut pair, the size of the mechanism is reduced, making the mechanism more compact.

[0047] Motor 28 is a servo frequency converter motor equipped with an absolute encoder, which can accurately control the running position to ensure repeatability and ensure that the motor position zero point is not lost after power failure and restart. It is simple to program and easy to adjust. The vertical sliding group 2 includes a pre-pressing stop block group and a final pressing stop block group, which are used for mechanical protection limit at the pre-pressing position and the final pressing position, respectively, so that the vertical sliding group 2 has an overtravel protection function. The vertical movable frame 26 and the fixed frame 1 are respectively equipped with corresponding travel rulers 29 and pointers 14 for position correction during mechanism debugging. The vertical movable frame 26 is fixed with a vertically extending guide rail 27, and the fixed frame 1 is fixed with sliders 12 and 13. The sliders 12 and 13 cooperate with the guide rail 27 to allow the vertical movable frame 26 to slide vertically relative to the fixed frame 1.

[0048] Driven by the motor 28, the driving wheel 241 connected to it transmits torque to the driven wheel 243 via the belt 242. The lead screw 23, directly connected to the driven wheel 243, then rotates. Through its interaction with the nut 11, the circular motion is converted into linear motion, allowing the vertical sliding assembly 2 to reciprocate up and down along the fixed frame 1 via the guide rail 27 and the sliders 12 and 13. When the mechanism moves downwards for pre-pressing, the pre-pressing stop block assembly provides mechanical limit protection; when the mechanism moves downwards for final pressing, the final pressing stop block assembly provides mechanical limit protection.

[0049] A horizontal sliding assembly mounting base 21 is fixed to the top of the vertical movable frame 26. The horizontal sliding assembly 3 includes an insert component mounting base 32, a guide slot seat 33, a slide plate 35, a drive cylinder 31, and a guide slot mounting plate 37. The guide slot mounting plate 37 is fixed to the horizontal sliding assembly mounting base 21, the drive cylinder 31 is fixed to the vertical movable frame 26, the output end 39 of the drive cylinder 31 is connected to the slide plate 35, the guide slot seat is fixed to the guide slot mounting plate 37, the slide plate 35 is horizontally slidably disposed within the guide slot seat 33, and the insert component mounting base 32 is fixed to the slide plate 35. The drive cylinder 31 drives the insert component mounting base 32 to move horizontally. The horizontal sliding assembly also includes working position stop block groups 36, 36' and exit position stop block groups 38, 38', which are used to mechanically limit the horizontal sliding assembly 3 in the working position and exit position, respectively. The slide plate 35 engages with the guide groove in the guide slot seat 33, allowing for horizontal sliding. A self-lubricating friction plate 34 is installed within the guide groove, effectively reducing maintenance workload. The horizontal sliding of the insert assembly mounting base 32 is directly driven by a cylinder, resulting in a simple, direct, and fast structure.

[0050] The insert assembly 4 is fixed on the insert assembly mounting base 32. The insert assembly 4 includes an insert mounting plate 43, a final pressing insert 41, and a pre-pressing insert 42 located below it.

[0051] The horizontal sliding assembly 3 drives the insert assembly 4 to reciprocate horizontally between the working position and the exit position. The vertical sliding assembly 2 drives the insert assembly 4 to move up and down, sequentially passing through the pre-pressing preparation position, the pre-pressing position, the final pressing preparation position, and the final pressing position from top to bottom. The pre-pressing stop block assembly includes a first pre-pressing stop block 22 and a second pre-pressing stop block 22', and the final pressing stop block assembly includes a first final pressing stop block 25 and a second final pressing stop block 25'. The first pre-pressing stop block 22 is provided with a stop end 221 and a clearance part 222, and the second pre-pressing stop block 22' is provided with a stop end 221' and a clearance part 222'. In the pre-pressing position, the stop ends of the first pre-pressing stop block 22 and the second pre-pressing stop block 22' contact each other to form a protective limit, and there is a gap between the first final pressing stop block 25 and the second final pressing stop block 25' in the vertical direction. After pre-pressing is completed, the insert assembly 4 first moves horizontally to the exit position. At this time, the stop end 221 of the first pre-pressing stop block 22 and the stop end 221' of the second pre-pressing stop block 22' have a gap in the horizontal direction. Then, the insert assembly 4 moves downward to the final pressing preparation position, and then moves horizontally to the working position. At this time, the stop end 221 of the first pre-pressing stop block 22 and the stop end 221' of the second pre-pressing stop block 22' respectively embed into the avoidance parts 222' and 222, so that the insert assembly 4 can move downward to the final pressing position. When moving to the final pressing position, the first final pressing stop block 25 and the second final pressing stop block 25' contact each other to form a protective limit.

[0052] The pressing unit is the core component of the pressing machine, such as... Figure 5 As shown, multiple automotive door cover pressing modules of the present invention are combined to form the pressing unit of the pressing machine. The pressing unit adopts a modular design to reduce the types of spare parts. The automotive door cover pressing modules can be adapted to complex part shapes by adjusting the installation angle.

[0053] like Figure 6 As shown, the pressing process of the car door cover pressing module is as follows:

[0054] The insert assembly is in the initial position (1). When the motor receives the working signal, the motor drives the vertical movable frame and the horizontal sliding assembly connected to it to rise to the highest point position (2), which is the pre-pressing preparation position and the exit position. After detecting the positioning signal, the drive cylinder of the horizontal sliding assembly is fed back, and the cylinder starts to move (3). The insert assembly is moved horizontally to the position above the part to be pressed area (4), which is the pre-pressing preparation position and the working position. After detecting the cylinder positioning signal, the feedback signal is sent to the motor, and the motor runs under the control of the frequency converter, driving the insert assembly to move downward until the pre-pressing position and the working position (5), and the pre-pressing insert 42 pre-presses the outer plate of the part. After the pre-pressing is completed, the motor runs and drives the insert assembly to move upward and separate from the part to the pre-pressing preparation position and the working position (6). Then, the drive cylinder makes a return movement, driving the insert assembly away from the part to a safe position, which is the pre-pressing preparation position and the exit position (7). The positioning signal is transmitted to the motor, which drives the insert assembly downwards to the final pressing preparation position and the exit position (8). Subsequently, the drive cylinder moves horizontally to the position above the part to be pressed area (9), which is the final pressing preparation position and the working position. At this time, after detecting the cylinder positioning signal, a feedback signal is sent to the motor, which operates under the control of the frequency converter, driving the insert assembly downwards (10). Until the final pressing position and the working position (11), the final pressing insert 41 performs final pressing on the outer plate of the part. After the final pressing is completed, the motor moves upwards to disengage from the part, which is the final pressing preparation position and the working position (12). Subsequently, the horizontal drive cylinder performs a return motion (13). This moves the insert assembly away from the part back to the initial position (14), thus ending one pressing cycle.

[0055] The above are merely preferred embodiments of the present invention and are illustrative rather than restrictive. The structure and connection methods of the components in the present invention can be varied, and any equivalent transformations and improvements made based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
