Description

Technical Field

[0001] This invention relates to the field of composite material molding technology, and in particular to an automatic bonding device. Background Technology

[0002] Composite materials, with their advantages of high strength, lightweight, corrosion resistance, and fatigue resistance, are widely used in aerospace, rail transportation, new energy equipment and other fields. Adhesive bonding is one of the core processes for the preparation of finished composite materials. Compared with traditional mechanical connection methods such as riveting and welding, it has the characteristics of uniform stress distribution, good component integrity, no stress concentration, good sealing performance and significant weight reduction. It can effectively adapt to the molding and assembly needs of complex irregular composite material structures.

[0003] Currently, in the bonding process of large composite material products in the industry, the direct alignment and bonding process of upper and lower molds is commonly used. This involves fixing the upper mold and relying on the unidirectional lifting of the lower mold to complete the mold alignment, or fixing the lower mold and relying on the unidirectional lifting of the upper mold to complete the mold alignment. In this method, when attaching the upper component to the upper mold, the operator needs to hold the upper component for installation and adjustment, which is labor-intensive and inconvenient for the installation of the upper component. At the same time, due to the weight of the upper mold, it cannot be placed in a high position. Under the restriction of the lower mold, the installation and operation space of the upper mold is further reduced, making the installation of both the upper and lower components inconvenient. Therefore, how to improve the convenience of installation of the upper and lower components and the stability of the mold alignment between the upper and lower molds is a key research direction in the industry.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an automatic gluing device. This device comprises a lateral transfer mechanism that moves the lower mold assembly laterally, and two lifting drive mechanisms that rotate and raise / lower the upper mold assembly. The lateral transfer mechanism moves the lower mold assembly from the gluing position to the loading position, facilitating the operator's installation of the lower component onto the first product positioning seat. The lifting drive mechanisms move the upper mold assembly from the rotating position to the gluing position. When the upper mold assembly is in the rotating position, a rotary drive device rotates the second product positioning seat upwards, and then the lifting drive device moves it downwards, facilitating the operator's installation of the upper component onto the second product positioning seat. The cooperation between the lateral transfer mechanism and the lifting drive mechanisms improves the ease of installation of the upper and lower components. Furthermore, the lateral transfer mechanism and the two lifting drive mechanisms are electrically connected to a controller, enabling automatic control of the gluing operation of the upper and lower mold assemblies. The structural design is ingenious.

The rack is slidably mounted on the lifting and moving seat, and the first telescopic cylinder is fixedly mounted on the lifting and moving seat and connected to the rack. The rack is connected to the upper mold assembly and meshes with the rack. The first telescopic cylinder drives the gear to rotate through the sliding of the rack, thereby driving the upper mold assembly to flip.

[0008] As a preferred embodiment, both sides of the upper mold assembly are mounted on corresponding lifting and moving seats via a rotatable connection structure. The rotatable connection structure includes a fixed seat mounted on the lifting and moving seat and a rotating seat mounted on the upper mold plate. The fixed seat contains a bearing, and a rotating shaft passes through the bearing. One end of the rotating shaft is fixedly connected to the rotating seat, and the gear is fixed to the other end of the rotating shaft.

[0009] As a preferred embodiment, the rotating seat is located in the middle of the side of the upper template. The rotating seat has protrusions on both the top and bottom surfaces of the upper template. The upper template is fitted between the two protrusions. A reinforcing structure connecting the two rotating seats is provided in the middle of the top surface of the upper template. The reinforcing structure includes a square tube frame, a fixing block, and a connecting block. The fixing block is fixed to both sides of the square tube frame and is used to fix the square tube frame in the middle of the top surface of the upper template. The connecting block is fixed to the end of the square tube frame and connected to the top surface of the rotating seat.

[0010] As a preferred embodiment, both the rotating seat and the fixed seat have positioning holes on both sides of the rotating shaft, and positioning pins for limiting the rotation of the rotating seat relative to the fixed seat are detachably installed in the positioning holes.

[0011] As a preferred embodiment, the upper template is provided with a horizontal block and a vertical block connected to the horizontal block, and the lifting and moving seat is provided with a stop block for the horizontal block to block and restrict the upper template from rotating in a first direction, and the vertical block can block against the lifting and moving seat to restrict the upper template from rotating in a second direction.

[0012] As a preferred embodiment, the lifting and moving seat is provided with a first guide post and a second guide post, the height of the second guide post being greater than the height of the first guide post. The lifting and moving seat is provided with a limiting device corresponding to the first guide post for limiting the lifting and moving seat to a flipped position. The limiting device includes a baffle plate that can abut against the top of the first guide post and a second telescopic cylinder that drives the baffle plate to extend and retract.

[0013] As a preferred embodiment, the upper template is provided with a third guide post, and correspondingly, the lower template is provided with a guide sleeve for the third guide post to be movably inserted. The lower template is also provided with a first height limiting post on the side of the guide sleeve to prevent the upper template from being pressed down excessively.

[0014] As a preferred embodiment, both the first and second product positioning seats include multiple positioning blocks arranged at intervals. Each positioning block is provided with multiple air intake holes and air channels connecting the multiple air intake holes. Both the first and second vacuum adsorption devices are provided with two air drums. Each air drum is connected to a first gas collecting block. The first gas collecting block is connected to two second gas collecting blocks. The air channels of the multiple positioning blocks are connected to the corresponding second gas collecting blocks to achieve synchronous vacuuming of the positioning blocks in four areas.

[0015] As a preferred embodiment, the lateral transfer mechanism and the two lifting drive mechanisms are all mounted on a bottom support frame, with the two lifting drive mechanisms arranged on both sides of the lateral transfer mechanism, and an air drum mounting bracket for mounting the air drum is provided on the side of the bottom support frame.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: The main feature is the use of a lateral transfer mechanism that moves the lower mold assembly laterally and two lifting drive mechanisms that rotate and lift the upper mold assembly. The lateral transfer mechanism moves the lower mold assembly from the bonding position to the loading position, facilitating the operator's installation of the lower component onto the first product positioning seat. The lifting drive mechanisms move the upper mold assembly from the flipping position to the bonding position. When the upper mold assembly is in the flipping position, the rotary drive device rotates the second product positioning seat upwards, and then the lifting drive device moves it downwards, facilitating the operator's installation of the upper component onto the second product positioning seat. The cooperation between the lateral transfer mechanism and the lifting drive mechanisms improves the ease of installation of the upper and lower components. Furthermore, the lateral transfer mechanism and the two lifting drive mechanisms are electrically connected to the controller, enabling automatic control of the bonding operation of the upper and lower mold assemblies. The structure is ingeniously designed.

[0017] Secondly, the first telescopic cylinder drives the gear to rotate through the sliding of the rack and pinion, which in turn drives the upper mold assembly to flip. This structure is subjected to force through tooth meshing, has a strong load-bearing capacity, is suitable for heavy-duty equipment, has fewer parts, is flexible in layout, only requires periodic lubrication, and is easy to troubleshoot and replace parts. The linear motion is smoothly converted into continuous rotation, and the start-stop and reversing actions are responsive.

[0018] Furthermore, the reinforced structure enhances the structural strength of the upper template, making it less prone to bending and deformation.

[0019] Furthermore, the placement of positioning pins, horizontal blocks, and vertical blocks prevents the upper mold assembly from rotating relative to the fixed seat during the installation of the upper component and during gluing. The cooperation between the limiting device and the first guide post prevents the upper mold assembly from shifting downwards during the flipping process. The placement of the first height limiting post prevents the upper mold assembly from shifting excessively downwards during mold closing, thus achieving stable mold closing between the upper and lower molds. The structural design is ingenious.

[0020] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0023] First, it should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Please refer to Figures 1 to 13 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a lower mold assembly 10, a lateral transfer mechanism 20, an upper mold assembly 30, two lifting drive mechanisms 40, and a controller 50.

[0025] The lower mold assembly 10 includes a lower template 11 and a first product positioning seat 12 disposed on the lower template 11. The first product positioning seat 12 is connected to a first vacuum adsorption device 13 for adsorbing and fixing the lower component 60 of the product onto the first product positioning seat 12. The transverse transfer mechanism 20 includes a transverse moving seat 21 and a transverse moving device 22. The lower template 11 is disposed on the transverse moving device 22. The transverse moving device 22 can drive the transverse moving seat 21 to move back and forth between the loading position of the lower mold assembly 10 and the gluing position of the lower mold assembly 10. The upper mold assembly 30 includes an upper template 31 and a second product positioning seat 32 disposed on the upper template 31. The second product positioning seat 32 is connected to a second vacuum adsorption device 33 for adsorbing and fixing the upper component 70 of the product onto the second product positioning seat 32. The lifting drive mechanism 40 includes a lifting movable seat 41, a lifting drive device 42, and a rotary drive device 43 disposed on the lifting movable seat 41. The rotary drive device 43 is connected to the upper mold assembly 30 and can drive the upper mold assembly 30 to rotate 180 degrees. The upper mold assembly 30 is disposed on the lifting movable seat 41 and is mounted above the transverse transfer mechanism 20. The lifting drive device 42 can drive the lifting movable seat 41 to move back and forth between the rotation position and the bonding position of the upper mold assembly 30. The lateral transfer mechanism 20 and the two lifting drive mechanisms 40 are all electrically connected to the controller 50.

[0026] Specifically, see Figure 1 and Figure 3 As shown, the lateral transfer mechanism 20 and the two lifting drive mechanisms 40 are all mounted on a bottom support frame 80. The two lifting drive mechanisms 40 are arranged on both sides of the lateral transfer mechanism 20. The lateral moving device 22 and the lifting drive device 42 are both driven by servo motors and lead screws. The lifting moving seat 41 and the lateral moving seat 21 are both connected to the corresponding lead screws through lead screw nuts. The bottom of the lateral moving seat 21 is slidably mounted on the bottom support frame 80 through the first slide rail. The lateral transfer mechanism 20 and the two lifting drive mechanisms 40 are all mounted on the bottom support frame 80 through corresponding bottom support plates 81.

[0027] See Figure 6 As shown, the rotary drive device 43 includes a rack 431, a gear 432, and a first telescopic cylinder 433. The rack 431 is slidably disposed on the lifting moving seat 41. The first telescopic cylinder 433 is fixedly disposed on the lifting moving seat 41 and connected to the rack 431. The rack 431 is connected to the upper mold assembly 30 and meshes with the rack 431. The first telescopic cylinder 433 drives the gear 432 to rotate through the sliding of the rack 431, thereby driving the upper mold assembly 30 to flip. The rack 431 is slidably disposed on the lifting moving seat 41 through a second slide rail. Further, see Figure 5 , Figures 8 to 10As shown, both sides of the upper mold assembly 30 are mounted on corresponding lifting and moving seats 41 via rotating connection structures 90. Each rotating connection structure 90 includes a fixed seat 91 mounted on the lifting and moving seat 41 and a rotating seat 92 mounted on the upper mold plate 31. A bearing 93 is installed in the fixed seat 91, and a rotating shaft 94 passes through the bearing 93. One end of the rotating shaft 94 is fixedly connected to the rotating seat 92, and the gear 432 is fixed to the other end of the rotating shaft 94. The bearing 93 is a high-load bearing. Gear 432 is fixed to the other end of rotating shaft 94 by the cooperation of locking nut 95 and key 96. Locking nut 95 restricts the axial displacement of gear 432 along rotating shaft 94, and key 96 restricts the rotation of gear 432 relative to rotating shaft 94. A bushing 97 is tightly fitted on rotating seat 92. One end of rotating shaft 94 is fixed to bushing 97, thereby driving rotating seat 92 to rotate. The bushing 97 reduces wear between rotating shaft 94 and rotating seat 92, and also reduces the difficulty of machining holes in rotating seat 92.

[0028] Preferred options, please refer to Figure 5 As shown, the rotating seat 92 is located in the middle of the side of the upper template 31. The rotating seat 92 has protrusions 921 on both the top and bottom surfaces of the upper template 31. The upper template 31 is fitted between the two protrusions 921. A reinforcing structure 100 connecting the two rotating seats 92 is provided in the middle of the top surface of the upper template 31. The reinforcing structure 100 includes a square tube frame 1001, a fixing block 1002, and a connecting block 1003. The fixing block 1002 is fixed to both sides of the square tube frame 1001 and is used to fix the square tube frame 1001 in the middle of the top surface of the upper template 31. The connecting block 1003 is fixed to the end of the square tube frame 1001 and connected to the top surface of the rotating seat 92. The square tube frame 1001, the fixing block 1002, and the connecting block 1003 are fixed together by welding, which strengthens the structural strength of the upper template 31 and makes the connection between the upper template 31 and the rotating seat 92 less prone to deformation.

[0029] See Figure 1 , Figure 2 and Figure 6As shown, both the rotating seat 92 and the fixed seat 91 have positioning holes 901 on both sides of the rotating shaft 94. Positioning pins 110 are detachably installed in the positioning holes 901 to restrict the rotation of the rotating seat 92 relative to the fixed seat 91. The upper template 31 is provided with a horizontal block 311 and a vertical block 312 connected to the horizontal block 311. The lifting moving seat 41 is provided with a stop block 411 for the horizontal block 311 to abut against, thus restricting the rotation of the upper template 31 in the first direction. The vertical block 312 can abut against the lifting moving seat 41 to restrict the rotation of the upper template 31 in the second direction. The upper template 31 is driven by the cooperation of the rack 431 and the gear 432. 1. When rotated 180 degrees, the upper template 31 stops rotating and remains horizontal because the horizontal block 311 hits the blocking block 411 or the vertical block 312 hits the lifting moving seat 41. At this time, the positioning pin 110 is inserted to further prevent the upper template 31 from rotating. The lifting moving seat 41 includes a lifting slide 412 and a lifting plate 413 connected to the lifting drive device 42. The lifting plate 413 is mounted on the lifting slide 412 by a mounting block 414. The positioning pin 110 can pass through the mounting block 414. The mounting block 414 can provide a placement position for the positioning pin 110, so that it can be more conveniently inserted into the positioning hole 901 and is not easily lost.

[0030] See Figure 6 and Figure 11 As shown, the lifting movable seat 41 is provided with a first guide post 415 and a second guide post 416. The height of the second guide post 416 is greater than the height of the first guide post 415. The lifting movable seat 41 is provided with a limiting device 120 corresponding to the first guide post 415 for limiting the lifting movable seat 41 to a flipped position. The limiting device 120 includes a baffle plate 1201 that can abut against the top of the first guide post 415 and a second telescopic cylinder 1202 that drives the baffle plate 1201 to extend and retract. The baffle plate 1201 and the first guide post 415 are connected. The cooperation of 15 can prevent the upper template 31 from falling. The height of the second guide post 416 is greater than the height of the first guide post 415, which can ensure that the second guide post 416 can still guide when the first guide post 415 loses its guiding function. Under this structure, the first guide post 415 has the functions of guiding and preventing the upper template 31 from falling. The structure is ingeniously designed. The bottom of the lifting moving seat 41 is provided with a second height limiting post 44. The second height limiting post 44 is located on the bottom support plate 81. The second height limiting post 44 can prevent the lifting moving seat 41 from moving too far down.

[0031] See Figure 2As shown, the upper template 31 is provided with a third guide post 313. Correspondingly, the lower template 11 is provided with a guide sleeve 111 for the third guide post 313 to be movably inserted. The cooperation between the third guide post 313 and the guide sleeve 111 further ensures that the upper mold assembly 30 and the lower mold assembly 10 can be accurately molded together. The lower template 11 is also provided with a first height limiting post 112 on the side of the guide sleeve 111 to prevent the upper template 31 from being pressed down too much. The first height limiting post 112 can prevent the upper mold assembly 30 from damaging the lower mold assembly 10. Locking blocks 130 are provided on the sides of the upper template 31 and the lower template 11 to lock the upper template 31 and the lower template 11 together. The setting of the locking blocks 130 can keep the upper template 31 and the lower template 11 in an adhesive state.

[0032] See Figure 4 , Figure 5 and Figure 7 As shown, both the first product positioning seat 12 and the second product positioning seat 32 include multiple positioning blocks 1401 arranged at intervals. Each positioning block 1401 is provided with multiple air suction holes and air channels connecting the multiple air suction holes. Both the first vacuum adsorption device 13 and the second vacuum adsorption device 33 are provided with two air drums 1402. Each air drum 1402 is connected to a first air collecting block 1403. The first air collecting block 1403 is connected to two second air collecting blocks 1404. The air channels of the multiple positioning blocks 1401 are connected to the corresponding second air collecting blocks 1404 to achieve simultaneous vacuuming of the positioning blocks 1401 in four areas. The upper template 31 and the lower template 11 are both divided into four areas, and each area is provided with multiple positioning blocks 1401. The arrangement of the four second air collecting blocks 1404 can more quickly adsorb and fix the upper component 70 and the lower component 60.

[0033] Specifically, an air drum mounting bracket 82 for mounting the air drum 1402 is provided on the side of the bottom support frame 80. Two first air collecting blocks 1403 at the first product positioning seat 12 are arranged on the side of the lower template 11 near the air drum mounting bracket 82. Two first air collecting blocks 1403 at the second product positioning seat 32 are arranged on the square tube frame 1001 to avoid damaging the platform of the upper template 31. This allows the square tube frame 1001 to both strengthen the structure 100 and provide installation positions for the first air collecting blocks 1403, demonstrating a clever structural design. A safety light curtain sensor 150 is also provided on the bottom support frame 80. If an operator is working within the range of the safety light curtain sensor 150, even if the switch is accidentally operated, the upper template assembly 30 will not have any lifting or rotating movements, ensuring the safety of the operator.

[0034] In this embodiment, the upper component 70 and the lower component 60 are components of a carbon fiber car hood.

[0035] The bonding steps of this embodiment are described in detail below: In step S1, the controller 50 drives the lifting drive device 42 to operate, which lifts the upper template 31 to a certain height. Then, the controller 50 drives the second telescopic cylinder 1202 to operate, which drives the baffle plate 1201 to block the first guide column 415 and prevent the upper template 31 from descending. In step S2, the controller 50 drives the horizontal drive device to move the lower template 11 to the loading position, so as to facilitate the rotation of the upper template 31 and the application of structural adhesive on the lower template 11. Step S3: Remove the positioning pin 110, and the controller 50 drives the rotation drive device 43 to run, causing the upper template 31 to rotate 180 degrees. Then, reinsert the positioning pin 110 to fix the upper template 31. In step S4, the controller 50 drives the second telescopic cylinder 1202 to retract the baffle 1201, and the lifting drive device 42 drives the upper template 31 to descend to abut the second height limit column 44, so that the upper mold assembly 30 can install the upper component 70. At this time, the lower mold assembly 10 can install the lower component 60 and then apply glue. Step S5: After the upper mold assembly 30 is installed with the upper component 70 and the lower mold assembly 10 is installed with the lower component 60, the lifting drive device 42 drives the upper template 31 to lift, and then the rotation drive device 43 drives the upper template 31 to rotate and reset. Then, the horizontal drive device drives the lower template 11 to move and reset. In step S6, the lifting drive device 42 drives the upper template 31 to descend and close with the lower template 11.

[0036] The key design focus of this invention is: The main feature is the use of a lateral transfer mechanism that moves the lower mold assembly laterally and two lifting drive mechanisms that rotate and lift the upper mold assembly. The lateral transfer mechanism moves the lower mold assembly from the bonding position to the loading position, facilitating the operator's installation of the lower component onto the first product positioning seat. The lifting drive mechanisms move the upper mold assembly from the flipping position to the bonding position. When the upper mold assembly is in the flipping position, the rotary drive device rotates the second product positioning seat upwards, and then the lifting drive device moves it downwards, facilitating the operator's installation of the upper component onto the second product positioning seat. The cooperation between the lateral transfer mechanism and the lifting drive mechanisms improves the ease of installation of the upper and lower components. Furthermore, the lateral transfer mechanism and the two lifting drive mechanisms are electrically connected to the controller, enabling automatic control of the bonding operation of the upper and lower mold assemblies. The structure is ingeniously designed.

[0037] Secondly, the first telescopic cylinder drives the gear to rotate through the sliding of the rack and pinion, which in turn drives the upper mold assembly to flip. This structure is subjected to force through tooth meshing, has a strong load-bearing capacity, is suitable for heavy-duty equipment, has fewer parts, is flexible in layout, only requires periodic lubrication, and is easy to troubleshoot and replace parts. The linear motion is smoothly converted into continuous rotation, and the start-stop and reversing actions are responsive.

[0038] Furthermore, the reinforced structure enhances the structural strength of the upper template, making it less prone to bending and deformation.

[0039] Furthermore, the placement of positioning pins, horizontal blocks, and vertical blocks prevents the upper mold assembly from rotating relative to the fixed seat during the installation of the upper component and during gluing. The cooperation between the limiting device and the first guide post prevents the upper mold assembly from shifting downwards during the flipping process. The placement of the first height limiting post prevents the upper mold assembly from shifting excessively downwards during mold closing, thus achieving stable mold closing between the upper and lower molds. The structural design is ingenious.

[0040] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
