Description

Technical Field

[0001] The invention relates to the technical field of steel door production, and in particular to automatic gluing and pressing equipment for steel door processing. Background Art

[0002] The finished steel door is made by spraying adhesive on the upper and lower layers of steel plates, then sticking the filler inside the glued steel plate, and then sticking another glued steel plate on the filler before closing. In this process, the gluing process of the steel plate is crucial, because it is related to whether the steel plate can be tightly bonded with the internal filler. In this process, the uniformity of spraying the adhesive on the steel plate will also affect the production quality of the finished steel door.

[0003] For example, Chinese patent CN114345638U discloses an automatic gluing and pressing device for glass door production. The automatic gluing and pressing device cooperates with the workbench, mold mounting plate and servo motor to enable the robot gluing arm to cooperate with the movement of the mold mounting plate between two workbenches to work in a cycle, thereby reducing the standby time and effectively improving the production efficiency of the gluing and pressing device. However, the automatic gluing and pressing device cannot achieve gluing and pressing on the same device at the same time. It occupies a large area during the production of glass doors, and the equipment cost is high, which is not conducive to saving resources. Therefore, we propose an automatic gluing and pressing device for steel door processing. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic gluing and pressing device for processing steel doors, which can realize gluing and pressing on the same device at the same time to achieve the effect of saving resources.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic gluing and pressing device for steel door processing, comprising a base, a bracket installed on the base, a steel plate placed on the bracket, a vertical plate slidably connected to the base and located at the front and rear sides of the steel plate, a top plate connecting the two vertical plates, a driving component installed on the base for driving the vertical plates to reciprocate on the base, and a glue supply component installed on the base, the two vertical plates are rotatably connected with a rotating shaft that passes through the vertical plates, a mounting frame is fixedly installed between the two rotating shafts, a gluing component connected to the glue supply component is installed inside the mounting frame, a half gear located on the opposite side of the vertical plate is installed outside the rotating shaft, a rack plate is installed on the base, an arc groove is opened on the vertical plate, a connecting component that moves in the arc groove is installed on the mounting frame, a release groove connected to the arc groove is also installed on the vertical plate, and a tightening component is movably installed in the release groove.

[0006] When the vertical plate moves to the right side of the steel plate, the half gear on the outside of the rotating shaft meshes with the rack plate on the base, so that the mounting frame rotates between the two vertical plates. At this time, the glue outlet of the glue coating assembly rotates from the bottom to the side, and the original right side of the mounting frame rotates to the bottom. Then, another steel plate is placed on top of the steel plate that has been coated with glue. The driving assembly continues to start and drives the mounting frame on the inner side of the vertical plate to move left, and the two steel plates are pressed together. The gluing and pressing functions are integrated into one device, and the automatic switching of the gluing and pressing functions can be realized, which saves resources and is more convenient to operate.

[0007] When the vertical plate moves, it drives the gluing component on the inner side of the mounting frame to move rightward on the upper side of the steel plate to apply glue to the steel plate. The mounting frame is pressed tightly in the arc groove through the connecting component to ensure that the gluing component does not shake during gluing and the gluing of the steel plate is not affected.

[0008] When the half gear outside the rotating shaft meshes with the rack plate on the base to drive the mounting frame to rotate, the connecting component rotates synchronously in the arc groove, and rotates from the arc groove to the release groove to fit tightly with the clamping component, fixing the position of the mounting frame after rotation, so that the mounting frame will not deflect when pressing the steel plate, thereby improving the pressing effect of the steel plate.

[0009] The present invention is further configured as follows: the driving assembly includes two support plates 1 and 2 on the top of the base, a guide rod installed between the two support plates 1, a screw rotatably connected between the two support plates 2, and a servo motor installed on the base to drive the screw to rotate.

[0010] The present invention is further configured as follows: one of the vertical plates is slidably connected to the outside of the guide rod, and the other vertical plate is threadedly connected to the outside of the screw rod.

[0011] By adopting the above technical solution, the servo motor starts to drive the screw to rotate, thereby driving the vertical plate at the corresponding position to move left and right on the bottom plate. The vertical plate at the corresponding position drives the other vertical plate to rotate outside the guide rod through the top plate, so that the mounting frame hinged between the two vertical plates can move left and right with the vertical plates to glue and press the steel plates.

[0012] The present invention is further configured as follows: the glue supply assembly includes a glue storage cylinder installed on the base, a bracket installed on the base and a glue pump installed on the bracket, the glue pump is connected to the glue storage cylinder, and an electric heating wire (not shown in the figure) is also installed inside the glue storage cylinder.

[0013] By adopting the above technical solution, the glue pump is started to extract the glue in the glue storage cylinder and send it to the glue coating component to coat the steel plate with glue. The electric heating wire can heat the glue in the glue storage cylinder to prevent the glue in the glue storage cylinder from solidifying and affecting the glue output effect.

[0014] The present invention is further configured as follows: the glue coating assembly includes a glue outlet pipe installed on the inner side of the mounting frame, a plurality of glue outlet nozzles connected to the bottom of the glue outlet pipe, and a hose connecting the glue pump and the glue outlet pipe.

[0015] By adopting the above technical solution, the glue extracted by the glue pump is sent to the glue outlet pipe through the hose and sprayed by the glue outlet nozzle to coat the surface of the steel plate with glue. The setting of the hose can be expanded or compressed as the glue outlet pipe moves while conveying glue.

[0016] The present invention is further configured as follows: two rack plates are provided and are respectively located on the same horizontal line with the two half gears; in an initial state, the latching teeth on the half gears are located below the rotating shaft.

[0017] By adopting the above technical solution, when the half gear outside the rotating shaft moves with the mounting frame to engage with the rack plate on the base to drive the mounting frame to rotate, the locking tooth on the half gear rotates to the top of the rotating shaft, and then when the mounting frame moves to the left to press the steel plate, the bottom of the half gear is smooth and will not be stuck with the rack plate, thereby realizing automatic switching of the gluing and pressing functions without affecting the use of the pressing function.

[0018] The present invention is further configured as follows: the mounting frame is a rectangular frame and the bottom of its inner wall is an opening; the length of the mounting frame is smaller than its width; and scrapers are further installed on the front and rear sides of the mounting frame.

[0019] By adopting the above technical solution, the bottom of the mounting frame is set as an opening to facilitate the glue nozzle to apply glue. The length of the mounting frame is smaller than its width so that after the mounting frame is rotated, the height of the bottom of the mounting frame will move up, which is convenient for placing another steel plate on the steel plate that has been coated with glue for pressing. The scraper can move synchronously with the mounting frame to scrape off the glue overflowing during the pressing process, thereby improving the pressing effect of the steel plate.

[0020] The present invention is further configured as follows: the connecting assembly includes a connecting sleeve mounted on the mounting frame, a sliding block movably connected to the inside, a connecting spring connecting the sliding block and the inner wall of the connecting sleeve, and a connecting column mounted on the sliding block and passing through the connecting spring and resting against the inner wall of the arc groove.

[0021] By adopting the above technical solution, when the vertical plate moves, it drives the glue discharge nozzle on the inner side of the mounting frame to move rightward on the upper side of the steel plate to apply glue to the steel plate. The mounting frame is limited in the arc groove by the connecting sleeve and the connecting column and relies on the squeezing of the connecting spring 1 to make the connecting column press tightly in the arc groove, thereby ensuring that the glue discharge nozzle will not shake when applying glue and ensuring that the gluing of the steel plate is not affected.

[0022] The present invention is further configured as follows: the pressing assembly comprises a second sliding plate slidably connected to the release groove and a second connecting spring connecting the second sliding plate and the inner wall of the release groove.

[0023] By adopting the above technical solution, when the half gear outside the rotating shaft meshes with the rack plate on the base to drive the mounting frame to rotate, the connecting column rotates synchronously in the arc groove, and rotates from the arc groove to the release groove and fits tightly against the sliding plate 2, and then the position of the mounting frame after rotation is fixed by the mutual squeezing force of the connecting spring 1 and the connecting spring 2, so that the mounting frame will not deflect when pressing the steel plate, thereby improving the pressing effect of the steel plate.

[0024] The present invention is further configured as follows: a push-out rod passing through the half gear is installed on the resisting assembly, the push-out rod is installed on the sliding plate 2 and passes through the connecting spring 2, and an arc-shaped strip hole for the push-out rod to pass through is opened on the half gear, and the curvature of the arc-shaped strip hole is greater than the curvature of the arc-shaped groove.

[0025] By adopting the above technical solution, after the rotating mounting frame moves to the left to press the steel plate, the push-out rod is used to squeeze the sliding block 2 to push the connecting column out of the release groove, thereby releasing the fixation of the mounting frame. Then, the mounting frame is rotated to rotate the glue discharge nozzle to the top of the steel plate, and the connecting column moves in the arc groove and adheres to the inner wall of the arc groove, and the glue coating work is carried out again on the next steel plate. The curvature of the arc strip hole is greater than the curvature of the arc groove, so that the push-out rod will not interfere with the rotation of the half gear.

[0026] The beneficial effects of the present invention are:

[0027] 1. The half gear on the outside of the rotating shaft is meshed with the rack plate on the base, so that the mounting frame rotates between the two vertical plates when the gluing component is moving. At this time, the glue outlet of the gluing component rotates from the bottom to the side, and the original right side of the mounting frame rotates to the bottom. Then, another steel plate is placed on top of the steel plate that has been coated with glue. The driving component continues to start and drives the mounting frame on the inner side of the vertical plate to move left to press the two steel plates. The gluing and pressing functions are integrated into one device, and the automatic switching of the gluing and pressing functions can be realized, which saves resources and is more convenient to operate.

[0028] 2. When the vertical plate moves, it drives the gluing component on the inner side of the mounting frame to move rightward on the upper side of the steel plate to apply glue to the steel plate. The mounting frame is pressed tightly in the arc groove through the connecting component to ensure that the gluing component does not shake during gluing and the gluing of the steel plate is not affected.

[0029] 3. When the half gear outside the rotating shaft meshes with the rack plate on the base to drive the mounting frame to rotate, the connecting component rotates synchronously in the arc groove, and rotates from the arc groove to the release groove to fit tightly with the clamping component, fixing the position of the mounting frame after rotation, so that the mounting frame will not deflect when pressing the steel plate, thereby improving the pressing effect of the steel plate.

[0030] 4. The rotation of the half gear and the rack plate is used to realize the automatic switching from the gluing function to the pressing function. After the half gear moves with the mounting frame to mesh with the rack plate on the base and drives the mounting frame to rotate, the clamping tooth on the half gear rotates to the top of the rotating shaft. Then, when the mounting frame moves to the left to press the steel plate, the bottom of the half gear is smooth and will not be stuck with the rack plate, thus realizing the automatic switching between the gluing and pressing functions without affecting the use of the pressing function.

[0031] 5. The scraper can move synchronously with the mounting frame to scrape off the glue overflowed during the pressing process, thereby improving the pressing effect of the steel plate.

[0032] 6. After the rotating mounting frame moves to the left to press the steel plate, use the push-out rod to squeeze the sliding block 2 to push the connecting column out of the release groove to release the fixation of the mounting frame. Then the mounting frame rotates to rotate the glue nozzle to the top of the steel plate. The connecting column moves in the arc groove and fits tightly against the inner wall of the arc groove, making it convenient to re-glueize the next steel plate. The curvature of the arc strip hole is greater than that of the arc groove, so that the push-out rod will not interfere with the rotation of the half gear.

[0033] 7. Set the mounting frame to a rectangular frame. The length of the mounting frame is smaller than its width so that after the mounting frame rotates, the height of the bottom of the mounting frame will move up, making it convenient to place another steel plate on the steel plate that has been coated with glue for pressing.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-6The present invention provides an automatic gluing and pressing device for processing steel doors, comprising a base 1, a bracket 2 installed on the base 1, a steel plate 3 placed on the bracket 2, a vertical plate 4 slidably connected to the base 1 and located at the front and rear sides of the steel plate 3, a top plate 17 connecting the two vertical plates 4, a driving component 5 installed on the base 1 to drive the vertical plates 4 to reciprocate on the base 1, and a glue supply component 6 installed on the base 1, two vertical plates 4 are rotatably connected to a rotating shaft 7 that penetrates the vertical plates 4, and the two vertical plates 4 are rotatably connected to the rotating shaft 7 that penetrates the vertical plates 4. A mounting frame 8 is fixedly installed between the rotating shafts 7, a glue coating component 9 connected to the glue supply component 6 is installed inside the mounting frame 8, a half gear 11 located on the opposite side of the vertical plate 4 is installed outside the rotating shaft 7, a rack plate 12 is installed on the base 1, an arc groove 13 is opened on the vertical plate 4, a connecting component 14 that can move in the arc groove 13 is installed on the mounting frame 8, and a release groove 15 connected to the arc groove 13 is also installed on the vertical plate 4, and a tightening component 16 is movably installed in the release groove 15.

[0044] The steel plate 3 to be coated with glue is placed on the bracket 2, and the driving component 5 is started to drive the two vertical plates 4 to move back and forth on the base 1. The mounting frame 8 is hinged on the vertical plate 4 through the rotating shaft 7. When the vertical plate 4 moves, the gluing component 9 on the inner side of the mounting frame 8 moves to the right above the steel plate 3, and then the glue supply component 6 is started to provide glue to the gluing component 9 to coat the surface of the steel plate 3. When the vertical plate 4 moves to the right side of the steel plate 3, the half gear 11 outside the rotating shaft 7 is meshed with the rack plate 12 on the base 1, so that the mounting frame 8 The mounting frame 8 rotates between the two vertical plates 4 when the gluing component 9 moves. At this time, the glue outlet of the gluing component 9 rotates from the bottom to the side, and the original right side of the mounting frame 8 rotates to the bottom. Then another steel plate 3 is placed on the steel plate 3 that has been coated with glue. The driving component 6 continues to start and drives the mounting frame 8 on the inner side of the vertical plate 4 to move left, and the two steel plates 3 are pressed together. The gluing and pressing functions are integrated into one device, and the automatic switching of the gluing and pressing functions can be realized, which saves resources and is more convenient to operate.

[0045] When the vertical plate 4 moves, it drives the glue coating component 9 on the inner side of the mounting frame 8 to move rightward on the upper side of the steel plate 3 to coat the steel plate 3 with glue. The mounting frame 8 is pressed tightly in the arc groove 13 through the connecting component 14 to ensure that the glue coating component 9 does not shake during the coating, thereby ensuring that the coating of the steel plate 3 is not affected.

[0046] When the half gear 11 outside the rotating shaft 7 meshes with the rack plate 12 on the base 1 to drive the mounting frame 8 to rotate, the connecting component 14 rotates synchronously in the arc groove 13, and rotates from the arc groove 13 to the release groove 15 to be tightly attached to the clamping component 16, fixing the position of the mounting frame 8 after rotation, so that the mounting frame 8 will not deflect when pressing the steel plate 3, thereby improving the pressing effect of the steel plate 3.

[0047] The driving assembly 5 includes two support plates 1 51 and two support plates 2 52 on the top of the base 1, a guide rod 53 installed between the two support plates 1 51, a screw rod 54 rotatably connected between the two support plates 2 52, and a servo motor 55 installed on the base 1 to drive the screw rod 54 to rotate, wherein one of the vertical plates 4 is slidably connected to the outside of the guide rod 53, and the other vertical plate 4 is threadedly connected to the outside of the screw rod 54.

[0048] The servo motor 55 starts to drive the screw 54 to rotate, thereby driving the vertical plate 4 at the corresponding position to move left and right on the bottom plate 1. The vertical plate 4 at the corresponding position drives another vertical plate 4 to rotate outside the guide rod 53 through the top plate 17, so that the mounting frame 8 hinged between the two vertical plates 4 can move left and right with the vertical plates 4 to glue and press the steel plate 3.

[0049] The glue supply component 6 includes a glue storage cylinder 61 installed on the base 1, a bracket 62 installed on the base 1 and a glue pump 63 installed on the bracket 62. The glue pump 63 is connected to the glue storage cylinder 61. An electric heating wire (not shown in the figure) is also installed inside the glue storage cylinder 61. The glue pump 63 is started to extract the glue in the glue storage cylinder 61 and send it to the glue coating component 9 to coat the steel plate 3 with glue. The electric heating wire can heat the glue in the glue storage cylinder 61 to prevent the glue in the glue storage cylinder 61 from solidifying and affecting the glue output effect.

[0050] The glue coating assembly 9 includes a glue outlet pipe 91 installed on the inner side of the mounting frame 8, a plurality of glue outlet nozzles 92 connected to the bottom of the glue outlet pipe 91, and a hose 93 connecting the glue pump 63 and the glue outlet pipe 91. The glue extracted by the glue pump 63 is delivered to the glue outlet pipe 91 through the hose 93 and sprayed by the glue outlet nozzle 92 to coat the surface of the steel plate 3 with glue. The hose 93 can be arranged so that the glue outlet pipe 91 can be transported with glue and can also be expanded or compressed as the glue outlet pipe 91 moves.

[0051] The rack plates 12 are provided with two and are respectively located on the same horizontal line with the two half gears 11. In the initial state, the latching teeth on the half gears 11 are below the rotating shaft 7. When the half gear 11 outside the rotating shaft 7 moves with the mounting frame 8 to engage with the rack plate 12 on the base 1 to drive the mounting frame 8 to rotate, the latching teeth on the half gear 11 rotate to the top of the rotating shaft 7. Then when the mounting frame 8 moves left to press the steel plate 3, the bottom of the half gear 11 is smooth and will not be stuck with the rack plate 12, thereby realizing the automatic switching of the gluing and pressing functions without affecting the use of the pressing function.

[0052] The mounting frame 8 is a rectangular frame and the bottom of its inner wall is an opening. The length of the mounting frame 8 is smaller than its width. Scrapers 10 are also installed on the front and rear sides of the mounting frame 8. The bottom of the mounting frame 8 is set as an opening to facilitate the glue nozzle 92 to apply glue. The length of the mounting frame 8 is smaller than its width so that after the mounting frame 8 is rotated, the height of the bottom of the mounting frame 8 will move up, which is convenient for placing another steel plate 3 on the steel plate 3 that has been coated with glue for pressing. The scraper 10 can move synchronously with the mounting frame 8 to scrape off the glue overflowing during the pressing process, thereby improving the pressing effect of the steel plate 3.

[0053] The connecting assembly 14 includes a connecting sleeve 141 installed on the mounting frame 8, a sliding block 142 movably connected to the inside, a connecting spring 143 connecting the sliding block 142 and the inner wall of the connecting sleeve 141, and a connecting column 144 installed on the sliding block 142 and penetrating the connecting spring 143 and abutting against the inner wall of the arc groove 13. When the vertical plate 4 moves, it drives the glue discharge nozzle 92 on the inner side of the mounting frame 8 to move rightward on the upper side of the steel plate 3 to apply glue to the steel plate 3. The mounting frame 8 is limited in the arc groove 13 by the connecting sleeve 141 and the connecting column 144, and the connecting column 144 can be pressed tightly in the arc groove 13 by relying on the squeezing of the connecting spring 143, so as to ensure that the glue discharge nozzle 92 will not shake during gluing and ensure that the gluing of the steel plate 3 is not affected.

[0054] The clamping assembly 16 includes a sliding plate 161 slidably connected to the release groove 15 and a connecting spring 162 connecting the sliding plate 161 and the inner wall of the release groove 15. When the half gear 11 outside the rotating shaft 7 engages with the rack plate 12 on the base 1 to drive the mounting frame 8 to rotate, the connecting column 144 rotates synchronously in the arc groove 13, and rotates from the arc groove 13 to the release groove 15 to be tightly attached to the sliding plate 161, and then relies on the mutual squeezing force of the connecting spring 143 and the connecting spring 2 162 to fix the position of the mounting frame 8 after rotation, so that the mounting frame 8 will not deflect when pressing the steel plate 3, thereby improving the pressing effect on the steel plate 3.

[0055] The resisting assembly 16 is provided with a resisting rod 19 passing through the half gear 11, and the resisting rod 19 is installed on the sliding plate 161 and passes through the connecting spring 162. The half gear 11 is provided with an arc-shaped strip hole 18 for the resisting rod 17 to pass through, and the curvature of the arc-shaped strip hole 18 is greater than the curvature of the arc-shaped groove 13. After the rotating mounting frame 8 is moved to the left to press the steel plate 3, the resisting rod 19 is used to squeeze the sliding block 161 to push the connecting column 144 out of the release groove 15, and the fixing of the mounting frame 8 is released. Then, the mounting frame 8 is rotated to rotate the glue discharge nozzle 92 to the top of the steel plate 3, and the connecting column 144 moves in the arc-shaped groove 13 and is tightly attached to the inner wall of the arc-shaped groove 13, and the glue coating work is performed on the next steel plate 3 again. The curvature of the arc-shaped strip hole 18 is greater than the curvature of the arc-shaped groove 13, so that the resisting rod 19 will not interfere with the rotation of the half gear 11.
