Description

Technical Field

[0001] This utility model relates to the field of door and window frame manufacturing technology, and in particular to a frame glue injection machine. Background Technology

[0002] After the frame of door and window frame products is manufactured, glue needs to be injected at the joints of the frame members to stabilize the frame. The existing glue injection method is to manually inject glue into the glue injection hole by hand holding a glue injection gun. However, there are multiple glue injection holes on the frame, which are scattered in various parts of the frame. Manual glue injection requires a lot of effort and is not conducive to the rapid production of the frame. Therefore, there is an urgent need for a device that can automatically inject glue into the frame. Utility Model Content

[0003] The purpose of this invention is to provide a frame gluing machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A frame glue dispensing machine, comprising:

[0006] frame;

[0007] A clamping mechanism includes two clamping frames that extend in a front-to-back direction. The two clamping frames are movable on the frame in a left-to-right direction and in a direction that moves closer to or further away from each other, forming a clamping space between the two clamping frames.

[0008] A conveying mechanism comprising a conveyor belt extending in a front-to-back direction, the conveyor belt being movable in a left-to-right direction on the frame, the conveyor belt being located below the clamping space;

[0009] The dispensing mechanism has a dispensing end that can move within the clamping space.

[0010] This technical solution has at least the following beneficial effects: After the corner brackets and rods of the frame are installed and fixed in the previous process, the frame is conveyed to the clamping space via a conveyor belt. When the frame is conveyed to the predetermined position, the clamping mechanism clamps the frame from the left and right sides, fixing the frame in the clamping space. Then, the glue injection mechanism drives the glue injection end to move in the clamping space and connect to the glue injection hole of the frame to inject glue into the frame. This glue injection machine realizes the automated feeding, clamping and fixing and glue injection of the frame, reducing manual operation and greatly improving work efficiency.

[0011] As a further improvement to the above technical solution, the clamping frame is provided with a sliding clamping block and a fixed clamping block. The fixed clamping block is installed at one end of the clamping frame, and the sliding clamping block can move and be positioned on the other end of the clamping frame in a direction closer to or away from the fixed slider. The clamping space is located between the two sliding clamping blocks.

[0012] By adopting the above technical solution, the size of the clamping space is changed after the sliding clamping block moves. At this time, the two fixed clamping blocks on the two clamping frames clamp one side of the frame, and the two sliding clamping blocks after moving can clamp the other side of the frame, so as to achieve stable clamping of frames of different sizes and improve the practicality of the frame glue injection machine.

[0013] As a further improvement to the above technical solution, the sliding clamp and the fixed clamp are provided with elastic pads on the side of the other clamping frame.

[0014] By adopting the above technical solution, when the clamping frame moves to the position where the sliding clamping block and the fixed clamping block clamp the frame, the elastic pad can provide elasticity to the frame, reducing the risk of frame damage and deformation caused by rigid collision between the sliding clamping block and the fixed clamping block and the frame.

[0015] As a further improvement to the above technical solution, the clamping frame is provided with a first guide rail extending in the front-back direction, and the sliding clamping block is engaged with the first guide rail.

[0016] By adopting the above technical solution, the first guide rail is used to fix the movement path of the sliding clamping block, so that the sliding clamping block can move along the predetermined route and then move to the clamping frame with the clamping frame.

[0017] As a further improvement to the above technical solution, the frame is provided with a second guide rail extending in the left-right direction at both ends along the front-back direction, and the clamping frame is respectively engaged with the two second guide rails at both ends along the front-back direction.

[0018] By adopting the above technical solution, the second guide rail can fix the movement path of the clamping frame, so that the two clamping frames can move closer or further away from each other along the fixed path, thereby achieving synchronous clamping or releasing of the frame.

[0019] As a further improvement to the above technical solution, a first lead screw and a second lead screw are rotatably mounted on the frame. Both the first lead screw and the second lead screw extend in the left-right direction. The first lead screw is threaded to one of the clamping frames, and the second lead screw is threaded to the other clamping frame. The thread directions of the first lead screw and the second lead screw are opposite.

[0020] By adopting the above technical solution, the two lead screws rotate and stably drive the two clamping frames to move. Workers can use different specifications of first and second lead screws to drive the two clamping frames in advance according to the specifications of the target frame, so that the clamping space formed by the two clamping frames can be adapted to the target frame.

[0021] As a further improvement to the above technical solution, the first lead screw and the second lead screw are connected by a coupling.

[0022] By adopting the above technical solution, after connecting the first lead screw and the second lead screw with a coupling, the two rotate synchronously. First, only one drive mechanism is needed to drive one of the lead screws to achieve synchronous rotation of the first and second lead screws, thereby driving the two clamping frames to move relative to each other. This reduces the use of a drive mechanism and lowers the manufacturing cost of the dispensing machine. Second, by using a coupling to achieve synchronous rotation between the first and second lead screws, the two clamping frames move at the same speed, reducing the risk of one clamping frame touching the frame and pushing the frame relative to the conveyor belt, which could cause the frame to fall.

[0023] As a further improvement to the above technical solution, the clamping mechanism further includes two pairs of limiting top blocks, with one clamping frame and one pair of limiting top blocks corresponding to each other. Each limiting top block is installed on the frame, and the two limiting top blocks of the same pair are respectively located on the moving path of the corresponding clamping frame.

[0024] By adopting the above technical solution, the limiting top block limits the maximum movement distance of the corresponding clamping frame on the frame, preventing the clamping frame from moving excessively and falling out of the frame, causing damage to the equipment.

[0025] As a further improvement to the above technical solution, the frame is provided with a limiting wheel on the front side of the clamping space, and the limiting wheel can move and be positioned in the vertical direction of the frame.

[0026] By adopting the above technical solution, when the conveyor belt transports the frame to the clamping space, the limiting wheel rises and moves onto the frame's movement path. When the conveyor belt continues to run and moves the frame to abut against the limiting wheel, the conveyor belt stops running, the clamping frame moves, and the sliding clamp and the fixed clamp abut against the frame. At this time, the sliding clamp and the fixed clamp on the left and right sides respectively limit the left and right sides of the frame. Together with the limiting wheel, they completely fix the frame in the frame, so that the glue injection mechanism can inject glue into the glue injection hole at the fixed position, improving the stability of glue injection.

[0027] As a further improvement to the above technical solution, the length of the conveyor belt is greater than the length of the clamping space along the same direction.

[0028] By extending the conveyor belt beyond the clamping space, the conveyor belt can be connected to the previous process, thereby stably supporting the frame installed in the previous process. Attached Figure Description

[0039] During the manufacturing process of door and window frames, after the rods are assembled and locked, glue needs to be injected into the inside of the frame through the glue injection holes. After the glue is injected, the corners inside the frame are more secure and are not easy to loosen even if they are impacted. In addition, the glue injection can also fill the gaps in the corners of the profiles, enhancing the corner sealing performance. However, most of the existing glue injection process is done manually. Workers need to walk around the frame and inject glue into the glue injection holes at various locations, which is time-consuming and labor-intensive and not conducive to the rapid manufacturing of the frame.

[0040] Therefore, this application provides a frame glue injection machine, with reference to... Figure 1 , Figure 2 and Figure 3 The frame glue injection machine provided in this application includes a frame 1, a clamping mechanism 2, a conveying mechanism 3 and a glue injection mechanism 4. The conveying mechanism 3 conveys the frame to the clamping mechanism 2, and the clamping mechanism 2 fixes the frame. Finally, the glue injection mechanism 4 injects glue into the frame.

[0041] Specifically, the clamping mechanism 2 includes two clamping frames 21, which extend in the front-back direction. The two clamping frames 21 can move on the frame 1 in the left-right direction and move closer or further away from each other, forming a clamping space 201 between the two clamping frames 21; the conveying mechanism 3 includes a conveyor belt 31 extending in the front-back direction, which can move on the frame 1 in the left-right direction and is located below the clamping space 201; and the glue dispensing mechanism 4 has a glue dispensing end 41 that can move within the clamping space 201.

[0042] After the corner brackets and rods of the frame are installed and fixed in the previous process, the frame is transferred to the clamping space 201 via the conveyor belt 31. When the frame is conveyed to the predetermined position, the clamping mechanism 2 clamps the frame from the left and right sides, fixing the frame in the clamping space 201. Then, the glue injection mechanism 4 drives the glue injection end 41 to move in the clamping space 201 and connect to the glue injection hole of the frame to inject glue into the frame. This glue injection machine realizes the automated feeding, clamping and fixing and glue injection of the frame, reducing manual operation and greatly improving work efficiency.

[0043] Each of the two clamping frames 21 is equipped with a sliding clamping block 22 and a fixed clamping block 23. The fixed clamping block 23 is installed at the front end of the clamping frame 21, and the sliding clamping block 22 is installed at the rear end of the clamping frame 21. The sliding clamping block 22 can move and be positioned at the other end of the clamping frame 21 in a direction parallel to the front and back and toward or away from the fixed slider. The clamping space 201 is located between the two sliding clamping blocks 22. The two fixed clamping blocks 23 and the two sliding clamping blocks 22 form the four corners of the clamping space 201 on the horizontal plane projection. After the sliding clamping block 22 moves, it changes the size of the clamping space 201. At this time, the two fixed clamping blocks 23 on the two clamping frames 21 clamp one side of the frame, and the two sliding clamping blocks 22 after moving can clamp the other side of the frame, realizing stable clamping of frames of different sizes and improving the practicality of the frame gluing machine.

[0044] Specifically, each clamping block is equipped with a screw drive mechanism 5, which includes a drive motor and a drive screw. The drive motor is fixedly installed at the end of the clamping frame 21 away from the fixed clamping block 23. The drive screw is rotatably installed on the clamping frame 21 and connected to the output end of the drive motor. The sliding clamping block 22 is threadedly connected to the drive screw. When the drive motor is started and the drive screw is driven to rotate, the sliding clamping block 22 is moved, so that the distance between the sliding clamping block 22 and the fixed clamping block 23 is equal to the length of the frame to be glued. At this time, the sliding clamping block 22 and the fixed clamping block 23 can stably clamp the frame to be glued.

[0045] By moving the sliding clamping block 22, the size of the clamping space 201 can be changed, thereby achieving stable clamping of frames of different sizes and improving the practicality of the frame gluing machine.

[0046] If the sliding clamp 22 and the fixed clamp 23 directly clamp the frame, the rigid contact between them may cause the frame to be deformed under pressure. Therefore, it is necessary to change the contact relationship between the clamping mechanism 2 and the frame. An elastic pad is provided on the side of the sliding clamp 22 and the fixed clamp 23 near the other clamping frame 21. Specifically, the elastic pad can be made of rubber or sponge. When the clamping frame 21 moves to the point where the sliding clamp 22 and the fixed clamp 23 clamp the frame, the elastic pad can provide elasticity to the frame, reducing the risk of damage and deformation of the frame after the sliding clamp 22 and the fixed clamp 23 have a rigid collision with the frame.

[0047] The clamping frame 21 is provided with a first guide rail 24 extending in the front-back direction. The sliding clamping block 22 is engaged with the first guide rail 24. The first guide rail 24 is used to fix the movement path of the sliding clamping block 22, so that the sliding clamping block 22 can move along the predetermined route and then move with the clamping frame 21 to the clamping frame.

[0048] The frame 1 has two second guide rails 11 extending in the left and right directions at both ends along the front-back direction. The clamping frame 21 is respectively engaged with the two second guide rails 11 at both ends along the front-back direction. Specifically, the clamping frame 21 has a locking groove at both ends along the front-back direction. The locking groove engages with the second guide rail 11, so that the clamping frame 21 moves along the direction of the second guide rail 11. This allows the two clamping frames 21 to move closer to each other or further away from each other along a fixed route, so as to realize the synchronous clamping or releasing of the frame.

[0049] Reference Figure 4 A first lead screw 12 and a second lead screw 13 are rotatably mounted on the frame 1. Both the first lead screw 12 and the second lead screw 13 extend in the left-right direction. The first lead screw 12 is threaded to one of the clamping frames 21, and the second lead screw 13 is threaded to the other clamping frame 21. The threads of the first lead screw 12 and the second lead screw 13 are opposite in direction. The first lead screw 12 and the second lead screw 13 are connected by a coupling. The frame 1 is provided with a first rotating seat and a second rotating seat corresponding to the first lead screw 12 and the second lead screw 13, respectively. The first lead screw 12 passes through the first rotating seat and is connected to the coupling, and the second lead screw 13 passes through the second rotating seat and is connected to the coupling, thereby improving the stability of the first lead screw 12 and the second lead screw 13 when rotating. The frame 1 is provided with a lead screw drive motor, and the output end of the lead screw drive motor is fixedly connected to the first lead screw 12 or the second lead screw 13, thereby driving the first lead screw 12 and the second lead screw 13 to rotate synchronously.

[0050] After connecting the first lead screw 12 and the second lead screw 13 with a coupling, the two rotate synchronously. First, only one drive mechanism is needed to drive one of the lead screws to achieve synchronous rotation of the first lead screw 12 and the second lead screw 13, which in turn drives the two clamping frames 21 to move relative to each other. This reduces the use of a drive mechanism and lowers the manufacturing cost of the dispensing machine. Second, the coupling enables the first lead screw 12 and the second lead screw 13 to rotate at the same frequency, thereby allowing the two clamping frames 21 to move at the same speed. This reduces the risk of the frame falling off if one of the clamping frames 21 touches the frame and pushes the frame relative to the conveyor belt 31.

[0051] The clamping mechanism 2 also includes two pairs of limiting top blocks 25. One clamping frame 21 corresponds to one pair of limiting top blocks 25. Each limiting top block 25 is installed on the frame 1. The two limiting top blocks 25 of the same pair are located on the movement path of the corresponding clamping frame 21. The limiting top blocks 25 limit the maximum movement distance of the corresponding clamping frame 21 on the frame 1 to prevent the clamping frame 21 from moving excessively and falling out of the frame 1, causing damage to the equipment.

[0052] Reference Figure 5 The frame 1 is equipped with a limiting wheel 6 on one side of the clamping space 201. The limiting wheel 6 can move and be positioned in the vertical direction of the frame 1. Specifically, the frame 1 is equipped with a lifting cylinder with the output end of the lifting cylinder extending upward. The limiting wheel 6 is installed at the output end of the lifting cylinder and the rotation axis of the limiting wheel 6 extends in the vertical direction. When the conveyor belt 31 transports the frame to the clamping space 201, the limiting wheel 6 rises and moves to the moving path of the frame. When the conveyor belt 31 continues to run and moves the frame to abut against the limiting wheel 6, the conveyor belt 31 stops running, and the clamping frame 21 moves so that the sliding clamping block 22 and the fixed clamping block 23 abut against the frame. At this time, the sliding clamping block 22 and the fixed clamping block 23 on the left and right sides respectively limit the left and right sides of the frame. Together with the limiting wheel 6, they completely fix the frame in the frame 1, so that the glue injection mechanism 4 can inject glue into the glue injection hole at the fixed position, thereby improving the stability of glue injection.

[0053] The length of the conveyor belt 31 is greater than the length of the clamping space 201 in the same direction. By extending the conveyor belt 31 beyond the clamping space 201, the conveyor belt 31 can be connected to the previous process, thereby stably supporting the frame installed after the previous process.

[0054] In this embodiment, the glue injection mechanism 4 includes a robotic arm 42 and a glue injection gun. The glue injection gun is installed at the movable end of the robotic arm 42, and the glue injection end 41 is the end of the glue injection gun away from the robotic arm 42. The glue injection gun can be connected to the glue storage device through a pipe. When the frame is moved to the position in the clamping space 201, the robotic arm 42 drives the glue injection gun to move to the glue injection end 41 and insert it into the glue injection hole of the frame. The glue storage device is activated to introduce glue into the glue injection gun and inject it into the interior of the frame through the glue injection hole.
