Description

Technical Field

[0001] This utility model relates to the field of automotive assembly automation technology, specifically a tailgate BONDING tilting press. Background Technology

[0002] Driven by the trend of energy conservation and emission reduction in the automotive industry, lightweight plastic parts have become the mainstream choice for automotive exterior panels. Lightweighting processes typically employ a combination of plastic parts, which are primarily bonded using adhesives such as high-viscosity polyurethane.

[0003] When bonding panels, a flip press is needed to press the two panels together. However, traditional flip presses often rely on manual operation, which is not only inefficient, but also poses a significant safety hazard due to the instability of manual operation. In addition, they are not flexible enough, and the upper mounting frame can easily obstruct the lower mounting frame during loading and unloading, and can easily damage the surface of the outer panel during the flipping process.

[0004] Based on this, this utility model designs a tailgate BONDING tilting press to solve the above problems. Utility Model Content

[0005] This invention provides a tailgate BONDING tilting press to solve the technical problem that existing tilting presses rely on manual operation and have poor flexibility.

[0006] According to one aspect of the present invention, a tailgate bonding tilting press is provided, comprising a gantry truss, an upper mold mounting mechanism, and a lower mold mounting mechanism. The gantry truss includes a base and supports disposed at both ends along the length of the base. The upper mold mounting mechanism includes a lifting unit on the supports, mounting plates corresponding to the lifting units on the two supports, an upper mold mounting frame rotatably disposed between the two mounting plates, and a tilting motor fixed to one of the mounting plates. The lifting unit is used to drive the mounting plates to lift and lower, thereby driving the upper mold mounting frame to lift and lower. The tilting motor is used to drive the upper mold mounting frame to rotate along a horizontal axis. The upper mold mounting frame is used to mount an upper membrane assembly. The lower mold mounting mechanism includes a lower mold mounting frame and a driving unit. The lower mold mounting frame is slidably disposed on the base along the width direction of the base. The driving unit is used to drive the lower mold mounting frame to slide on the base. The lower mold mounting frame is used to mount a lower membrane assembly.

[0007] As a further embodiment of this utility model, the sliding stroke of the lower mold mounting bracket on the base is not less than the length of the lower mold mounting bracket in the width direction of the base.

[0008] As a further embodiment of this utility model, the driving unit includes a first lead screw rotatably mounted on the base, a threaded block threadedly engaged with the first lead screw, and a first driving component for driving the first lead screw to rotate. The threaded block is fixedly connected to the bottom end of the lower mold mounting frame. The length direction of the first lead screw coincides with the width direction of the base. The threaded block is used to drive the lower mold mounting frame to move along the length direction of the first lead screw under the drive of the first lead screw.

[0009] As a further embodiment of this utility model, a first slide rail is fixedly provided on the base, the length direction of the first slide rail coincides with the width direction of the base, and a first slider matching the first slide rail is provided at the bottom of the lower mold mounting bracket for sliding cooperation with the first slide rail.

[0010] As a further embodiment of this utility model, a support leg is provided below the side of the first slide rail away from the base, and the first drive member and the end of the first lead screw away from the base are both provided on the support leg.

[0011] As a further embodiment of this utility model, the lifting unit includes a second lead screw rotatably mounted on a bracket, a lifting sleeve threaded onto the second lead screw, and a second driving component for driving the second lead screw to rotate. The second lead screw is installed vertically, and two mounting plates are connected one-to-one with the lifting sleeves on the two brackets. The lifting sleeve is used to move along the second lead screw when the second lead screw rotates, thereby realizing the lifting of the mounting plates.

[0012] As a further embodiment of this utility model, a second slide rail is vertically fixed on the bracket, and a second slider that matches the second slide rail and is used for sliding cooperation with the second slide rail is fixed on the mounting plate.

[0013] As a further embodiment of this utility model, an anti-fall cylinder is provided at the bottom of the mounting plate.

[0014] As a further embodiment of this utility model, the upper mold mounting bracket is provided with rotating shafts at both ends in the length direction of the base, and the mounting plate is provided with bearings for mounting the rotating shafts. The flipping motor is located on one of the mounting plates and is fixedly connected to the rotating shaft at one end of the upper mold mounting bracket.

[0015] As a further embodiment of this utility model, the bracket is provided with a first positioning component, and the lower mold mounting frame is provided with a second positioning component. The first positioning component is used to position the lower membrane assembly mounted on the lower mold mounting frame, and the second positioning component is used to position the upper mold mounting frame and the lower mold mounting frame.

[0016] This utility model has the following beneficial effects:

[0017] This device uses a lifting unit to drive the upper mold mounting frame to rise and fall, and a tilting motor to drive the upper mold mounting frame to tilt. After tilting, the upper mold mounting frame descends and cooperates with the lower mold mounting frame to achieve bonding of the upper and lower mold film components, realizing automatic bonding. This ensures tilting and pressing accuracy, improving efficiency and increasing the overall stability of the device. Simultaneously, the lower mold mounting frame is slidably mounted on the base and moved by a drive unit. During loading or unloading, the lower mold mounting frame can be moved from below the upper mold mounting frame, causing a horizontal misalignment between the two. This prevents the upper part of the lower mold mounting frame from being obstructed by the upper mold mounting frame, facilitating the installation of the upper and lower mold film components. The overall device is more flexible in use. Furthermore, during the tilting process of the upper mold mounting frame, it effectively avoids the upper mold mounting frame, preventing surface damage to the upper or lower mold film components and ensuring the surface quality of the workpiece.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a tailgate BONDING tilting press, including a gantry truss 1, an upper mold mounting mechanism 2, and a lower mold mounting mechanism 3. The gantry truss 1 includes a base 11 and supports 12 located at both ends of the base 11 along its length. The upper mold mounting mechanism 2 includes a lifting unit on the supports 12, mounting plates 21 corresponding to the lifting units on the two supports 12, an upper mold mounting frame 22 rotatably disposed between the two mounting plates 21, and a tilting motor 23 fixed on one of the mounting plates 21. The lifting unit is used to drive the mounting plate 21 to lift and lower, thereby driving the upper mold mounting frame 22 to lift and lower. The tilting motor 23 is used to drive the upper mold mounting frame 22 to rotate along a horizontal axis. The upper mold mounting frame 22 is used to install the upper membrane assembly. The lower mold mounting mechanism 3 includes a lower mold mounting frame 31 and a driving unit. The lower mold mounting frame 31 is slidably disposed on the base 11 along the width direction of the base 11. The driving unit is used to drive the lower mold mounting frame 31 to slide on the base 11. The lower mold mounting frame 31 is used to install the lower membrane assembly.

[0028] During operation, the drive unit first drives the lower mold mounting bracket 31 to slide away from below the upper mold mounting bracket 22, causing the upper mold mounting bracket 22 and the lower mold mounting bracket 31 to be horizontally misaligned, so that the lower mold mounting bracket 31 is no longer obstructed by the upper mold mounting bracket 22. Then, the upper membrane assembly can be installed on the upper mold mounting bracket 22, and the lower membrane assembly can be installed on the lower mold mounting bracket 31. After the upper and lower membrane assemblies are installed, the tilting motor 23 drives the upper mold mounting bracket 22 to rotate along the horizontal axis to a set angle. The lower mold mounting frame 31 is misaligned in the horizontal direction. During the flipping process of the upper mold mounting frame 22, the upper mold mounting frame 22 and the upper membrane assembly will not come into contact with the lower template on the lower mold mounting frame 31, thus preventing damage to the surface of the upper or lower membrane assembly when the upper mold mounting frame 22 flips. After the flipping is completed, the drive unit drives the lower mold mounting frame 31 back below the upper mold mounting frame 22. Then, the lifting unit drives the mounting plate 21 to descend, thereby reducing the height of the upper mold mounting frame 22 and realizing the bonding of the upper and lower membrane assemblies.

[0029] This device uses a lifting unit to drive the upper mold mounting frame 22 to rise and fall, and a tilting motor 23 to drive the upper mold mounting frame 22 to tilt. After tilting, the upper mold mounting frame 22 descends and cooperates with the lower mold mounting frame 31 to achieve bonding of the upper and lower membrane components, realizing automatic bonding. This ensures tilting and pressing accuracy, improving efficiency while increasing the overall stability of the device. Simultaneously, the lower mold mounting frame 31 is slidably mounted on the base 11 and moved by a drive unit. This allows for loading or unloading of materials. The lower mold mounting bracket 31 is moved out from under the upper mold mounting bracket 22, so that the upper mold mounting bracket 22 and the lower mold mounting bracket 31 are misaligned in the horizontal direction. This prevents the upper part of the lower mold mounting bracket 31 from being blocked by the upper mold mounting bracket 22, making it easy to install the upper and lower mold film components of the lower mold mounting bracket 31. The overall device is more flexible to use. At the same time, during the flipping process of the upper mold mounting bracket 22, the lower mold mounting bracket 31 can be avoided, preventing surface damage to the upper or lower mold film components caused by the flipping process of the upper mold mounting bracket 22, and ensuring the surface quality of the workpiece.

[0030] Specifically, the sliding stroke of the lower mold mounting bracket 31 on the base 11 is not less than the length of the lower mold mounting bracket 31 in the width direction of the base 11, ensuring that the lower mold mounting bracket 31 has sufficient sliding stroke to move away from under the upper mold mounting bracket 22, so that the upper mold mounting bracket 22 and the lower mold mounting bracket 31 can be completely misaligned in the horizontal direction.

[0031] Specifically, such as Figure 3As shown, the drive unit includes a first lead screw 32 rotatably mounted on the base 11, a threaded block 33 threadedly engaged with the first lead screw 32, and a first drive member 34 for driving the first lead screw 32 to rotate. The threaded block 33 is fixedly connected to the bottom end of the lower mold mounting frame 31. The length direction of the first lead screw 32 coincides with the width direction of the base 11. The threaded block 33 is used to drive the lower mold mounting frame 31 to move along the length direction of the first lead screw 32 under the drive of the first lead screw 32.

[0032] The first drive member 34 drives the first lead screw 32 to rotate. The rotation of the first lead screw 32 drives the threaded block 33 to move along the length of the first lead screw 32. The threaded block 33 is fixedly connected to the lower mold mounting frame 31. Thus, the threaded block 33 can drive the lower mold mounting frame 31 to move along the length direction of the first lead screw 32. The length direction of the first lead screw 32 coincides with the width direction of the base 11, thereby causing the lower mold mounting frame 31 to move in the width direction of the base 11, realizing the misalignment of the lower mold mounting frame 31 and the upper mold mounting frame 22.

[0033] like Figure 3 As shown, the first driving component 34 is a motor, which is fixed to one end of the first lead screw 32 to drive the first lead screw 32 to rotate.

[0034] Specifically, a first slide rail 13 is fixedly installed on the base 11. The length direction of the first slide rail 13 coincides with the width direction of the base 11. A first slider 35 matching the first slide rail 13 is provided at the bottom of the lower mold mounting bracket 31 for sliding cooperation with the first slide rail 13, so as to realize the sliding installation of the lower mold mounting bracket 31.

[0035] like Figure 3 As shown, a first slide rail 13 is provided on the base 11. The lower mold mounting bracket 31 slides with the first slide rail 13 through the first slider 35 at its bottom end. The length direction of the first slide rail 13 coincides with the width direction of the base 11, so that the sliding direction of the lower mold mounting bracket 31 coincides with the width direction of the base 11. Through the cooperation of the first slide rail 13 and the first slider 35, the stability and positioning accuracy of the lower mold mounting bracket 31 during the sliding process can be ensured.

[0036] Furthermore, a support leg 14 is provided on the side of the first slide rail 13 away from the base 11. The first drive member 34 and the end of the first lead screw 32 away from the base 11 are both provided on the support leg 14. Since the lower mold mounting bracket 31 needs to be completely misaligned with the upper mold mounting bracket 22, the first lead screw 32 and the first slide rail 13 need to extend beyond the base 11. The support leg 14 is used to support the suspended ends of the first lead screw 32 and the first slide rail 13 to ensure the straightness of the first lead screw 32 and the first slide rail 13.

[0037] Specifically, the lifting unit includes a second lead screw 24 rotatably mounted on the bracket 12, a lifting sleeve 25 threadedly engaged with the second lead screw 24, and a second driving component 26 for driving the second lead screw 24 to rotate. The second lead screw 24 is installed vertically, and two mounting plates 21 are connected one-to-one with the lifting sleeves 25 on the two brackets 12. The lifting sleeves 25 are used to move along the second lead screw 24 when the second lead screw 24 rotates, thereby realizing the lifting of the mounting plates 21.

[0038] like Figure 3 As shown, a second lead screw 24 is rotatably mounted on the bracket 12 and is vertically installed. The bottom end of the mounting plate 21 is provided with a fixed sleeve that engages with the lifting sleeve 25, thereby achieving a fixed connection between the mounting plate 21 and the lifting sleeve 25. When the second drive member 26 drives the second lead screw 24 to rotate, the lifting sleeve 25, which is threaded onto the second lead screw 24, rises or falls along the lead screw, thereby driving the mounting plate 21 to rise or fall. The second lead screws 24 in the two brackets 12 rotate synchronously, causing the two mounting plates 21 to rise or fall synchronously, thus realizing the rise or fall of the upper mold mounting frame 22 between the two mounting plates 21.

[0039] Specifically, such as Figure 3 As shown, the second drive unit 26 adopts a dual-head motor, and the output shafts at both ends extend to the brackets 12 on both sides respectively. A reversing mechanism is fixedly installed at the lower end of the bracket 12. The reversing mechanism is used to transmit torque vertically, thereby transmitting the torque output by the dual-head motor to the vertically installed second lead screw 24.

[0040] Furthermore, a second slide rail 15 is vertically fixed on the bracket 12, and a second slider 27 that matches the second slide rail 15 is fixed on the mounting plate 21 for sliding cooperation with the second slide rail 15, so as to maintain the stability of the mounting plate 21 during the lifting process.

[0041] like Figure 3 As shown, a second slide rail 15 is also provided on the bracket 12. The second slide rail 15 is vertically fixed on the bracket 12. A second slider 27 is provided on the mounting plate 21, which slides in cooperation with the second slide rail 15. The sliding cooperation between the second slider 27 and the second slide rail 15 ensures the stability of the mounting plate 21 during the lifting process.

[0042] Furthermore, such as Figure 4 As shown, a fall-prevention cylinder 28 is provided at the bottom of the mounting plate 21. When the mounting plate 21 is rotated to the set position, the fall-prevention cylinder 28 extends and inserts its front end into the slot opened in the bracket 12, thereby preventing the mounting plate 21 from falling and increasing the safety of the overall device.

[0043] Specifically, such as Figure 4As shown, the upper mold mounting frame 22 has rotating shafts 221 at both ends of the base 11 along its length. The mounting plate 21 is provided with bearings 211 for mounting the rotating shafts 221. The flipping motor 23 is mounted on one of the mounting plates 21 and is fixedly connected to the rotating shaft 221 at one end of the upper mold mounting frame 22. The upper mold mounting frame 22 rotates on the mounting plate 21 through the rotating shafts 221 at both ends of the upper mold mounting frame 22 and the bearings 211.

[0044] Furthermore, such as Figure 3 As shown, the bracket 12 is equipped with a first positioning component 36, such as Figure 2 As shown, a second positioning component 37 is provided on the lower mold mounting frame 31. When the lower membrane assembly (this mechanism is not shown) needs to be replaced, the cylinder in the first positioning component drives the positioning pin to retract, thereby easily replacing the lower membrane assembly of other products. After the lower membrane assembly is replaced, the cylinder in the first positioning component drives the positioning pin to extend and abut against both sides of the lower membrane assembly in the length direction of the base 11, thereby achieving the positioning of the lower membrane assembly. The second positioning component also uses a cylinder to control the positioning pin. When the upper and lower membrane assemblies need to be molded together, the cylinder in the second positioning component drives the positioning pin to extend upward. The positioning pin cooperates with the positioning hole opened in the upper mold mounting frame to achieve the positioning between the lower mold mounting frame and the upper mold mounting frame, thereby achieving precise mold closing of the upper and lower membrane assemblies.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
