Description

Technical Field

[0001] The invention relates to the field of intelligent production equipment for door and window frames, and in particular to a frame assembly production line. Background Art

[0002] For frame structures such as door frames or window frames, during manufacturing, the profiles need to go through the corner code installation process and the frame assembly process in sequence, and then the profiles need to be assembled into a frame. Finally, the glass is embedded in the frame and fixed with glue to form a complete door frame or window frame.

[0003] The existing frame production line includes a main transport line and a secondary transport line which are parallel to each other on the horizontal plane. The main transport line transports two relatively opposite profiles of the frame to the corner code installation process and the assembly splicing process in turn, and the other two profiles are directly transported to the assembly splicing process through the secondary transport line. When the profile that does not need to be installed with the corner code is directly transported to the frame assembly process through the secondary transport line, it is spliced ​​and assembled with the profile that has been installed with the corner code. In this process, the secondary transport line needs to occupy more space in the factory on the horizontal plane, which is not conducive to laying multiple production lines in the factory. Therefore, there is an urgent need for a frame assembly production line with a smaller footprint, so that more production lines can be accommodated in the factory, thereby improving production efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a frame assembly production line to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the present invention to solve its technical problem is:

[0006] The frame assembly production line is characterized by comprising a frame, on which are provided:

[0007] An angle code installation mechanism, comprising a clamping unit and an angle code installation assembly, with the horizontal conveying direction of the angle code installation mechanism as a first direction, the clamping unit is provided with a clamping gap extending along the first direction, the clamping unit forms an avoidance space between the clamping gap and the frame, the angle code installation assembly is installed on the clamping unit, and at least one pair of the angle code installation assemblies is provided, and the two angle code installation assemblies of the same pair are respectively located at both sides of the clamping gap along the first direction, and the two angle code installation assemblies of the same pair both have a pushing end, and the pushing end can move toward or away from the clamping gap;

[0008] A frame assembly mechanism, which is installed at the conveying downstream of the angle code installation mechanism, the frame assembly mechanism includes an assembly unit and a first transfer device, the assembly unit is provided with a molding space, the first transfer device has a first clamping jaw, the first clamping jaw can move in a three-dimensional direction and rotate along an upper and lower axis;

[0009] A first conveyor belt, wherein the transmission starting end of the first conveyor belt is located upstream of the angle code installation mechanism, the transmission end passes through the avoidance space and extends along the first direction to the frame assembly mechanism, and the clamping gap, the transmission end of the first conveyor belt and the forming space are all located on the moving path of the first clamp.

[0010] The technical solution has at least the following beneficial effects: when the profile of the frame is fed into the feeding end of the angle code installation mechanism, the profile is first divided into a first profile that needs to be installed with an angle code and a second profile that does not need to be installed with an angle code, and the first profile is first put into the clamping gap of the angle code installation mechanism so that the first profile and the angle code installation component are relatively fixed, and then the angle code installation component is started so that the pushing end pushes the angle code located there, thereby pushing the angle code into the angle code slot at the end of the first profile, and the angle code installation components at both ends act simultaneously to fix the two ends of the first profile At the same time, the angle code is installed. At the same time, the second profile that does not need to be installed with the angle code is directly placed on the first conveyor belt, so that the second profile is directly transmitted to the input end of the frame assembly mechanism through the avoidance space, and then the first transfer device drives the first clamp to move, clamp the first profile from the clamping gap and enter the molding space, clamp the second profile from the conveying end of the first conveyor belt and enter the molding space, and make the first profile and the second profile connected end to end one by one, repeat the clamping process, clamp a pair of first profiles and a pair of second profiles to form a frame and fix them, thereby completing the assembly of the frame.

[0011] In this process, compared with the existing two transmission lines arranged in the horizontal direction, the second profile is transported by the first conveyor belt hidden under the clamping gap, and the two sets of horizontally arranged transmission structures are changed to be arranged up and down, thereby reducing the space required for setting up the second production line, and being able to reserve more space for the setting of other production lines, thereby improving the space utilization rate of the production workshop in the factory. At the same time, the setting of the secondary transport line usually sets up two sets of feeding mechanisms, as well as the transfer structure of the frame assembly mechanism that transports the second profile on the secondary transport line back to the main transport line. However, in the present application, only the first transfer device is used to simultaneously clamp and transport the first profile and the second profile on the angle code installation mechanism and the first conveyor belt, thereby reducing the number of transfer devices and reducing the equipment cost of the production line.

[0012] As a further improvement of the above technical solution, with the second direction being horizontally perpendicular to the first direction, the clamping unit includes a pair of clamping frames, the two clamping frames of the same pair are arranged along the second direction, the clamping gap is formed between the two clamping frames of the same pair, the two clamping frames of the same pair can move towards or away from each other on the frame, and the two angle code mounting assemblies of the same pair are respectively mounted on the two clamping frames of the same pair.

[0013] By adopting the above solution, after the two clamping frames slide relative to each other, the size of the space at the clamping gap changes accordingly, so that the two clamping frames can clamp first profiles of different lengths, thereby improving the adaptability of the angle code installation mechanism to first profiles of different lengths.

[0014] As a further improvement of the above technical solution, the angle code installation assembly includes a mounting seat, a storage bin, a push rod, a first driving member and a second driving member, the mounting seat is installed on the clamping frame, and a clamping groove with an upper opening is provided on the side of the mounting seat facing the clamping gap, the first driving member has a first movable end, the first movable end is located on the side of the mounting seat away from the clamping gap, the first movable end can slide on the clamping frame along the first direction, the storage bin is installed on the first movable end, the storage bin is provided with a plurality of storage grooves, the plurality of storage grooves are arranged along the first direction and all extend along the vertical direction, the bottoms of the plurality of storage grooves are connected with a through groove extending along the second direction, the through groove is opposite to the clamping groove, the second driving member includes a second movable end, the second movable end can slide on the clamping frame along the second direction, the push rod is located on the side of the storage bin away from the mounting seat, the push rod is connected to the second movable end, the pushing end is an end of the push rod close to the clamping gap, and the pushing end can move to pass through the through groove and enter the clamping groove.

[0015] Workers store angle codes in the storage slots of each storage bin in advance, and the angle codes in each storage slot are arranged in the vertical direction. After the first profile is installed in the clamping gap, the second driving member is started, so that the push rod moves in the second direction in the clamping space and passes through the storage bin through the through slot, pushing the angle code in the storage slot to move through the through slot to the clamping slot, and finally enters the first profile located at the clamping gap, thereby completing the angle code installation process of the first profile. When a lower angle code is pushed out, an upper angle code falls vertically downward to the through slot under its own weight, reducing the use of driving members for pushing the angle codes and reducing the equipment cost of the production line. After completing the installation of a row of angle codes in one of the storage slots, the first driving member is started to drive the entire storage bin to move until the through slot on the next storage slot is opposite to the push rod. At this time, the second driving member is started, and the push rod can continue to push the angle code to maintain the continuity of production.

[0016] By adopting the above solution, multiple storage slots arranged in an array can store multiple angle codes at one time, reducing the number of times the angle codes need to be frequently replenished. When different numbers of angle codes are required to assemble frames of different specifications, the needs can be better met without frequently interrupting the production process to add angle codes.

[0017] As a further improvement of the above technical solution, the assembly unit includes a pair of assembly racks, and the two assembly racks of the same pair can be moved and positioned on the frame in a direction approaching or moving away from each other, and the two assembly racks each include a single frame and a screw mounting assembly installed on the single frame. One assembly rack is provided with two single frames, and the two single frames of the same assembly rack can be moved and positioned on the same assembly rack in a direction approaching or moving away from each other, and the sliding directions of the assembly rack and the single frames are perpendicular to each other in the horizontal direction, and a plurality of the single frames enclose the molding space in the horizontal direction.

[0018] By adopting the above solution, for frame structures such as door frames or window frames of different length specifications, the relatively movable assembly racks and single racks can be flexibly adjusted according to the length of the assembled frames, and the size of the molding space can be changed by changing the spacing between two adjacent single racks, ensuring that the profiles have appropriate space for splicing during the assembly process, thereby improving the compatibility of the production line with frame products of different sizes.

[0019] As a further improvement of the above technical solution, the screw installation assembly includes a sliding seat and a screw locking unit, a pair of the screw locking units are arranged on the sliding seat, the two screw locking units on the same sliding seat correspond to two adjacent single frames respectively, and the multiple screw locking units have a screw locking head, which extends in a horizontal direction and toward the direction close to the corresponding single frame.

[0020] When installing the screws, first put the screws on the screw locking unit, then start the screw locking head, turn the screws and press the screws into the frame to complete the locking of the frame. This solution realizes the precise adjustment of the screw locking head in the horizontal direction, so that the screw locking head is statically and accurately aligned with the position where the screws need to be installed on the profile, effectively performing screw installation operations on the profile connection, and improving the adaptability of the production line to different profile layouts.

[0021] As a further improvement of the above technical solution, the sliding seat can be installed in a liftable manner on the single frame, and a lifting guide rail extending upwardly and obliquely is arranged on the sliding seat. A third driving member is arranged on the single frame, and the third driving member has a third movable end. The third movable end can slide in a horizontal direction on the single frame, and the third movable end is slidably connected to the lifting guide rail.

[0022] Through the linkage between the fifth movable end and the lifting guide rail, the sliding seat is driven to move in the vertical direction. First, the scheme realizes precise control of the movement of the sliding seat in the vertical direction through the third driving member, effectively improving the accuracy of height positioning during the screw installation process and ensuring the smooth progress of the screw installation operation. Second, different frame structures may have differences in the height direction. For example, some door frames or window frames may be designed with different shapes or levels, resulting in different height positions of screw holes. The sliding screw locking unit enables the production line to flexibly respond to these frame structures with different height requirements. There is no need to equip specific screw installation equipment for each special height situation, which improves the overall flexibility and versatility of the production line and reduces production costs and the complexity of equipment management.

[0023] As a further improvement of the above technical solution, the frame is provided with a loading mechanism upstream of the angle code installation mechanism, the loading mechanism includes a second conveyor belt and a second transfer device, the conveying starting end of the first conveyor belt is located in the loading mechanism and in front of the second conveyor belt, the second transfer device has a second clamp, the second clamp is located above the second conveyor belt, the second clamp can move in a two-dimensional direction on a vertical plane and rotate along an upper and lower axis, the conveying end of the second conveyor belt and the conveying starting end of the first conveyor belt are both located on the moving path of the second clamp.

[0024] Workers only need to place the profile directly on the second conveyor belt. When the second profile is conveyed to the end of the second conveyor belt, the second clamping claw will pick up the second profile and rotate until the second profile extends along the first direction, and then place the second profile on the first conveyor belt. Through this solution, first, the profile can be processed in a targeted manner. After the second profile is placed on the first conveyor belt, it extends along the first direction. After the first profile is clamped by two clamping frames at the clamping gap, it extends along the second direction. The second profile only needs a small space to pass through the angle code installation mechanism through the avoidance space, reducing the probability of the second profile colliding with the angle code installation mechanism or the first profile. Second, the automatic distinction and transfer function of the profile is realized through the automated second conveyor belt and the second clamping claw, without excessive manual intervention. In the large-scale production process, the workload of manually distinguishing and transporting profiles is reduced, and the labor cost and the errors that may be caused by manual operation are reduced.

[0025] As a further improvement of the above technical solution, the angle code installation mechanism also includes a third transfer device, and the third transfer device has a third clamping jaw, and the third clamping jaw can move between the feeding mechanism and the clamping gap.

[0026] The length direction of each profile on the second conveyor belt is parallel to the second direction. The third clamp moves into the feeding mechanism and clamps the first profile in parallel into the clamping gap. The first profile and the second profile are clamped independently by the third clamp and the second clamp, thereby speeding up the clamping rhythm of the first profile. This ensures that the production line can operate continuously and efficiently, improves production efficiency, and greatly reduces the need for manual intervention and labor costs in large-scale production scenarios. It also avoids the impact of fatigue, errors and other factors that may occur during manual operation on production, further improving the stability and reliability of the production process.

[0027] As a further improvement of the above technical solution, the frame is provided with a pair of sliders at the conveying end of the second conveyor belt, and the two sliders can slide on the frame along the second direction and towards or away from each other, and a positioning gap is formed between the two sliders.

[0028] By adopting the above scheme, when the profile moves to the end of the second conveyor belt, the two sliders move from the two ends of the second conveyor belt along the second direction toward each other, thereby pushing and clamping the profile located in the middle of the second conveyor belt along the second direction, so that the profile moves to a position where the center of gravity is located on the central axis of the second conveyor belt, making it easier for the second clamp to grasp the center of gravity of the profile, thereby improving the stability of the profile when being clamped and transferred, and reducing the risk of the profile falling and damaging the production line equipment, causing the production line to stop working.

[0029] As a further improvement of the above technical solution, the frame assembly production line is provided with a placement rack at the downstream of the frame assembly mechanism, and a transmission component is provided between the placement rack and the frame assembly mechanism, and the conveying starting end of the transmission component is located in the molding space and the conveying terminal is located at the placement rack.

[0030] By adopting the above solution, the assembled frame is transported to the display rack through the transmission component, thereby improving the overall automation level of the production line, reducing the workload of workers, and reducing the impact of errors during manual operation.

[0048] The existing frame production line includes a main transport line and a secondary transport line parallel to each other on the horizontal plane. The main transport line transports the two first profiles of the frame that need to be installed with corner codes to the corner code installation process and the assembly splicing part in sequence, and the other two second profiles that do not need to be installed with corner codes are directly transported to the assembly splicing part through the secondary transport line. When the second profiles that do not need to be installed with corner codes are directly transported to the frame assembly process through the secondary transport line, they are spliced ​​and assembled with the first profiles that have been installed with corner codes to form a frame. In this process, the secondary transport line needs to occupy more space in the factory on the horizontal plane, which is not conducive to laying multiple production lines in the factory. Therefore, there is an urgent need for a frame assembly production line with a smaller footprint, so that more production lines can be accommodated in the factory, thereby improving production efficiency.

[0049] To this end, the present application provides a frame assembly production line with a smaller footprint.

[0050] Reference Figure 1 , Figure 2 and Figure 3, a frame assembly production line, comprising a frame, with the horizontal conveying direction of the frame assembly production line as a first direction, and the horizontal direction perpendicular to the first direction as a second direction, and the frame is provided with:

[0051] Feeding mechanism 2, refer to Figure 4 The feeding mechanism 2 is used to arrange and transmit the first profile that needs to be installed with the angle code and the second profile that does not need to be installed with the angle code;

[0052] Angle code installation mechanism 3, refer to Figure 5 and Figure 6 , which is installed at the downstream of the feeding mechanism 2, the angle code installation mechanism 3 is used to install angle codes at the two ends of the first profile, and the angle code installation mechanism 3 is provided with a third transfer device 32, and the third transfer device 32 is used to transfer the first profile in the feeding mechanism 2 to the angle code installation mechanism 3;

[0053] Frame assembly 4, refer to Figure 5 , which is arranged downstream of the angle code installation mechanism 3, and the frame assembly mechanism 4 is used to combine and splice the first profile and the second profile transmitted thereto to form a frame;

[0054] The first conveyor belt 5, see Figure 3 and Figure 5 The transmission starting end of the first conveyor belt 5 is located in the feeding mechanism 2, and the transmission end passes through the angle code installation mechanism 3 and extends along the first direction to the frame assembly mechanism 4. The first conveyor belt 5 is used to transport the second profile.

[0055] The first profile is transmitted from the feeding mechanism 2 to the angle code installation mechanism 3 and the frame assembly mechanism 4 in sequence. The second profile is transmitted from the feeding mechanism 2 through the first conveyor belt 5 and the angle code installation mechanism 3 directly to the frame assembly mechanism 4. The frame assembly mechanism 4 combines, splices and fixes the two first profiles and the two second profiles, and finally combines the four profiles into a frame to complete the automated manufacturing of the frame.

[0056] Specifically, refer to Figure 4The feeding mechanism 2 includes a second conveyor belt 21 and a second transfer device 22. The second conveyor belt 21 is transmitted in a direction parallel to the first direction. The second transfer device 22 includes a transfer rail, a second transfer frame, a second mounting frame and a second clamping claw 221. The transfer rail is installed on the frame and is located directly above the second conveyor belt 21. The length direction of the transfer rail is parallel to the first direction. One end of the second transfer frame is slidably installed on the transfer rail along the first direction. The second mounting frame is lifted and installed on the second transfer frame. The second clamping claw 221 is installed on the second mounting frame and faces downward. The second jaw 221 is located above the second conveyor belt 21 and on the center line of the second conveyor belt 21. The second jaw 221 can rotate along the upper and lower axes on the second mounting frame. Through the second transfer frame and the second mounting frame, the second jaw 221 can move along the first direction and the upper and lower directions on the transfer guide rail. The conveying starting end of the first conveyor belt 5 is located in the loading mechanism 2 and in front of the second conveyor belt 21 along its own conveying direction. The conveying end of the second conveyor belt 21 and the conveying starting end of the first conveyor belt 5 are both located on the moving path of the second jaw 221.

[0057] Workers place multiple first profiles and second profiles on the second conveyor belt 21. When the profiles are transported to the end of the second conveyor belt 21, the second clamp 221 grabs the second profile, and then the second clamp 221 rotates so that the length direction of the second profile is parallel to the first direction, and then the second profile is placed on the first conveyor belt 5, so that the second profile can be directly transported through the angle code installation mechanism 3 to the frame assembly mechanism 4.

[0058] Further as a preferred embodiment, a second linear drive module for driving the second transfer frame to move on the transfer guide rail is installed on the transfer guide rail. The second linear drive module can be a belt linear drive module, a chain gear drive module or a screw motor drive module. In the present embodiment, the second linear drive module is a screw motor module. The screw is installed on the transfer guide rail. The driving end of the motor is connected to the screw. The slider 23 is threadedly connected to the screw. The slider 23 is fixedly connected to the second transfer frame. A stepper motor is installed on the second transfer frame. The output end of the stepper motor is connected to the second clamp 221. Through the linkage of the second linear drive module, the second transfer frame and the stepper motor, the second clamp 221 is driven to move along the first direction and the up and down direction in the feeding mechanism 2 and rotate along the up and down axis direction.

[0059] As a further preferred embodiment, the frame is provided with a pair of positioning units at the conveying end of the second conveyor belt 21, one positioning unit includes a slider 23 and a lifting roller 231, the two sliders 23 of the pair of positioning units are respectively arranged on both sides of the second conveyor belt 21 along the first direction and arranged in an array along the second direction, the two sliders 23 of the same pair of positioning units can be moved and positioned on the frame along the second direction and in a direction approaching or moving away from each other, a positioning gap is formed between the two sliders 23, the two lifting rollers 231 of the same pair of positioning units are respectively arranged on both sides of the second conveyor belt 21 along the first direction and arranged in an array along the second direction, and a plurality of lifting rollers 231 are arranged The lifting rollers 231 can be raised and lowered in the feeding mechanism 2 to protrude from the second conveyor belt 21. The rotation axes of the multiple lifting rollers 231 are horizontally parallel to the first direction. When the first profile or the second profile is transported to the end of the second conveyor belt 21, the lifting rollers 231 are raised to lift the first profile or the second profile and separate it from the second conveyor belt 21. Then the two sliders 23 move towards each other in the second direction, and finally clamp the first profile or the second profile. At this time, the second clamping jaw 221 is located directly above the center point of the profile. After grabbing the profile, the weight of the profile on both sides of the second clamping jaw 221 is equal, reducing the risk of the profile falling due to the offset of the center of gravity of the profile.

[0060] Further as a preferred embodiment, a storage rack 24 is provided at the end position along the first direction in the feeding mechanism 2, the storage rack 24 is located in front of the first conveyor belt 5 along its own conveying direction, and an installation gap is reserved between the storage rack 24 and the second conveyor belt 21 for placing the second profile into the first conveyor belt, the storage rack 24 is used to place the first profile, the storage rack 24 is located on the moving path of the second clamp 221, during the production process, the second clamp 221 grabs the second profile onto the first conveyor belt 5, and then grabs the first profile onto the storage rack 24, so as to facilitate the transfer of the first profile to the angle code installation mechanism 3, and reduce the interference between the third transfer device 32 and the second clamp 221 when the third transfer device 32 moves the first profile.

[0061] Specifically, refer to Figure 2 , Figure 3 and Figure 6The angle code installation mechanism 3 includes a clamping unit 31, an angle code installation component 33 and a third transfer device 32. The clamping unit 31 is provided with a clamping gap extending along the first direction. The clamping unit 31 forms an avoidance space 301 between the clamping unit 31 and the frame below the clamping gap. The angle code installation component 33 is installed on the clamping unit 31. A plurality of pairs of angle code installation components 33 are arranged along the first direction. Two groups of angle code installation components 33 of the same pair are respectively arranged on both sides of the clamping gap along the first direction. The two groups of angle code installation components 33 of the same pair are arranged in the second direction. The two angle code installation components 33 of the same pair both have a pushing end, which can be moved along the second direction toward or away from the clamping gap. The third transfer device 32 includes a third clamping jaw 321. The third clamping jaw 321 can move between the storage rack 24 of the feeding mechanism 2 and the clamping gap. The third clamping jaw 321 can move in the clamping gap between the plurality of pairs of angle code installation components 33.

[0062] The second profile that does not need to be installed with an angle code is directly placed on the first conveyor belt 5, so that the second profile is directly transmitted to the input end of the frame assembly mechanism 4 through the avoidance space 301. In this process, compared with the two existing transmission lines set in the horizontal direction, the second profile is transported by the first conveyor belt 5 hidden under the clamping gap, and the two sets of horizontally set transmission structures are changed to be set up up and down, which reduces the space required for setting up the second production line, and can reserve more space for the setting of other production lines, thereby improving the space utilization rate of the production workshop in the factory. At the same time, when setting up a secondary transportation line, two sets of feeding mechanisms are usually set up, as well as a transfer structure for transporting the second profile on the secondary transportation line back to the frame assembly mechanism 4 on the main transportation line. However, in the present application, only the first transfer device 43 is used to simultaneously clamp and transport the first profile and the second profile on the angle code installation mechanism 3 and the first conveyor belt 5, thereby reducing the number of transfer devices and reducing the equipment cost of the production line.

[0063] As for the first profile, the third clamp 321 is started to grab the first profile that has passed through the second clamp 221 to the storage rack 24 and put it into the clamping gap of one pair of angle code installation components 33, so that the first profile and the angle code installation components 33 are relatively fixed, and then the angle code installation components 33 are started so that the pushing end pushes the angle code located there, thereby pushing the angle code into the angle code slot at the end of the first profile. The angle code installation components 33 at both ends act at the same time, and the angle codes are installed at both ends of the first profile at the same time.

A pair of clamping frames 311 corresponds to a pair of angle code installation components 33 one by one, and the two angle code installation components 33 of the same pair are respectively installed on the corresponding two clamping frames 311 of the same pair. Through the two slidable clamping frames 311, the space size at the clamping gap changes accordingly, so that the two clamping frames 311 can clamp first profiles of different lengths, thereby improving the adaptability of the angle code installation mechanism 3 to first profiles of different lengths and improving the practicality of the entire frame assembly production line.

[0065] Further as a preferred embodiment, each pair of two clamping frames 311 is provided with corresponding clamping drive members, and the clamping drive members are used to drive the two clamping frames 311 to move towards or away from each other.

The bidirectional screw is rotatably mounted on the frame, and the two ends of the bidirectional screw are respectively threadedly connected to the two clamping frames 311 of the same pair. The motor is mounted on the frame, and the output end of the motor can be connected to the bidirectional screw through a gear set. When the motor is started to rotate forward or reverse, the bidirectional screw is driven to rotate clockwise or counterclockwise, thereby driving the two clamping frames 311 of the same pair to move on the frame.

[0066] Further as a preferred embodiment, a plurality of pairs of clamping rails extending along the second direction are provided on the frame, a pair of clamping rails corresponds to a pair of clamping frames 311, and the two clamping frames 311 of the same pair are each provided with a pair of clamping grooves, and the two clamping grooves on the same clamping frame 311 are respectively clamped to the two clamping rails of the same pair, and the two clamping frames 311 of a pair are each connected to the corresponding pair of clamping rails, and the sliding path of the clamping frame 311 is fixed by the clamping rails to improve the sliding stability of the clamping frame 311 on the frame.

[0067] As a further preferred embodiment, refer to Figure 7 and Figure 8The angle code installation assembly 33 includes a mounting seat 331, a storage bin 332, a push rod 333, a first driving member 334 and a second driving member 335.

The first driving member 334 has a first movable end, which is located on the side of the mounting seat 331 away from the clamping gap. The first movable end can slide on the clamping frame 311 along the first direction. The storage bin 332 is installed at the first movable end. The storage bin 332 is provided with a plurality of storage grooves 337. The plurality of storage grooves 337 are arranged along the first direction and extend in the vertical direction.

[0068] Workers store the angle codes in the storage slots 337 of each storage bin 332 in advance. The angle codes in each storage slot 337 are arranged in the vertical direction. Through the multiple arranged storage slots 337, multiple angle codes can be stored at one time, reducing the number of times the angle codes need to be frequently replenished. When different numbers of angle codes are required to assemble frames of different specifications, the demand can be better met without frequently interrupting the production process to add angle codes.

[0069] After the first profile is installed in the clamping gap, the second driving member 335 is started, so that the push rod 333 moves along the second direction in the clamping space and passes through the storage bin 332 through the through slot 338, pushing the angle code in the storage slot 337 to move to the clamping slot 336 through the through slot 338, and finally enters the first profile located at the clamping gap, thereby completing the angle code installation process of the first profile. When a lower angle code is pushed out, an upper angle code falls vertically downward to the through slot 338 under its own weight, reducing the use of driving members for pushing the angle codes and reducing the equipment cost of the production line. After the installation of a row of angle codes in one of the storage slots 337 is completed, the first driving member 334 is started, driving the entire storage bin 332 to move until the through slot 338 on the next storage slot 337 is opposite to the push rod 333. At this time, the second driving member 335 is started, and the push rod 333 can continue to push the angle code to maintain the continuity of production.

The size of the molding space can be changed by changing the distance between two adjacent single frames 412, ensuring that there is suitable space for splicing of profiles during the assembly process, thereby improving the compatibility of the production line with frame products of different sizes.

[0075] Further as a preferred embodiment, the frame assembly mechanism 4 is provided with an assembly rack 411 driving member and a single rack 412 driving member.

The two third transfer slide rails 432 are arranged along the second direction and are located at both ends of the second direction in the frame assembly mechanism 4. The fourth transfer slide rail 433 extends along the second direction, and the two ends of the fourth transfer slide rail 433 are respectively installed on the two third transfer slide rails 432. The fourth transfer slide rail 433 can be moved and positioned along the first direction on the third transfer slide rail 432, and the first mounting frame is slidably installed on the fourth transfer slide rail 433 along the second direction. The first mounting frame is lifted and installed on the first mounting frame.

Through the third transfer slide rail 432 and the fourth transfer slide rail 433, the first clamp 431 can be moved arbitrarily in three-dimensional directions.

The first clamp 431 rotates and clamps the second profile, and places the second profile in the molding space between two adjacent single frames 412 on the same assembly frame 411. After the two first profiles and the two second profiles are placed in the molding space, the screw installation components 413 on each single frame 412 work to fix the first profile, the second profile and the built-in angle code connected in the molding space to form a complete frame.

At this time, the fifth drive member 422 is synchronously started to rotate the screwdriver 424, turn the screw and press the screw into the frame to complete the locking of the frame. This scheme uses the fourth drive member 421 and the fifth drive member 422 to achieve precise adjustment of the screwdriver 424 in the horizontal direction close to or away from the single frame 412, so that the screwdriver 424 is accurately aligned with the position on the profile where the screw needs to be installed, effectively performing the screw installation operation on the profile connection, and improving the adaptability of the production line to different profile layout conditions.
