Detailed Description
The invention is described in detail below with reference to the figures and examples. The following experimental examples and examples are intended to further illustrate but not limit the invention.
Referring to fig. 2 to 4, the present invention provides an automatic assembly line 100 for a door frame connecting rod 200. The door frame connecting rod automatic assembly line 100 comprises a frame 10, a conveying device 20 fixedly arranged on the frame 10, a connecting rod mounting device 30 and a position sensor 40.
The frame 10 includes a base 11 having a feeding port 101 and a discharging port 102, and a mounting seat 12 disposed on a side of the base 11. The frame 10 is used to support the transportation device 20 and the connecting rod installation device 30, in this embodiment, the frame 10 is fixed to a processing plant and is a fixed structure, and in other embodiments of the present invention, it is also possible to add universal wheels or other moving devices to the frame 10 to enable the frame to have a moving function, and all of them are within the protection scope of the present invention.
Specifically, the base 11 includes a seat portion 111, an extending table 112 formed by extending the seat portion 111 from the two sides of the direction from the feeding port 101 to the discharging port 102, a limiting plate 113 arranged in parallel and at an interval relative to the transportation device 20, a guiding plate 114 arranged at the end of the limiting plate 113 close to the feeding port 101 and integrally formed with the limiting plate 113, and at least two connecting arms 115.
The orthographic projection of the limiting plate 113 to the transportation device 20 completely falls in the middle of the transportation device 20, meanwhile, a gap 103 for a door frame profile (not shown) to pass through is reserved between the limiting plate 113 and the extension table 112 on the two sides, and the width of the gap 103 is not smaller than that of the door frame profile.
The width of the guide plate 114 gradually increases along the direction from the material inlet 101 to the material outlet 102. According to the arrangement, after door frame sectional materials enter the door frame connecting rod automatic assembly line 100 through the feeding port 101, the space for the door frame sectional materials to pass through is gradually reduced until the width is reduced to the width of the gap 103 to be kept.
The connecting arms 115 are used for fixedly connecting the limiting plate 113, the guide plate 114 and the extension table 112. The limiting plate 113 and the guiding plate 114 are arranged to form the gap 103 between the extending table 112 for the door frame profile to pass through, and the connecting arm 115 ensures that the limiting plate 113 and the guiding plate 114 do not contact the transportation device 20, thereby ensuring the normal operation of the transportation device 20.
The conveying device 20 is arranged along the direction from the feeding port 101 to the discharging port 102, and is used for conveying the door frame profile from the feeding port 101 to the discharging port 102.

The installation box 32 includes a box body 321, a pre-installation passage 322 provided in the box body 321, and a screw storage space 323 provided in the box body 321 and spaced from the pre-installation passage 322. The pre-installation passage 322 is communicated with the guide belt 311, and the screw tightening device 33 sequentially penetrates through the screw storage space 323 and the pre-installation passage 322.
It should be noted that, after the mounting plate 202 enters the guide belt 311, there are two positions, that is, the front and back surfaces (the end having the hinge 203 is the front surface) cannot be screened out uniformly through the guide belt 311. Therefore, the pre-installation channel 322 includes a first channel 3221 communicating with the lead strip 311 and a second channel 3222 formed by bending and extending vertically from an end of the first channel 3221 far away from the lead strip 311.
The shape of the cross section of the first channel 3221 is configured to match the cross section of the mounting plate 202, that is, the first channel 3221 is provided with a space having a shape matching the hinge 203, when the mounting plate 202 enters the guide strip 311 in a reverse form, and when the mounting plate 202 is transported to the inlet of the first channel 3221, the mounting plate 202 cannot match the shape of the first channel 3221, so that the mounting plate 202 cannot fall off, and further, the operation is continued until the mounting plate falls off into the recycling bin.
Preferably, the depth of the first channel 3221 is n × H, n is a natural number greater than or equal to 1, and H is the height of a single mounting plate 202. That is, in the first passage 3221, a plurality of the mounting plates 202 are stacked, and when the number of the mounting plates 202 in the first passage 3221 is too large, the depth of the first passage 3221 is set such that the upper surface of the highest mounting plate 202 is parallel to the bottom surface of the lead tape 311, so that the following mounting plate 202 can continue to run until it falls into the recycling bin 34 without being blocked due to the uneven bottom surface of the lead tape 311.
The outlet end of the second channel 3222 is disposed opposite to the gap 103, and the first channel 3221 and the second channel 3222 are both perpendicular to the disposition direction of the gap 103.
The screw storage space 323 includes a storage space 3231 and a positioning space 3232 communicating with the storage space 3231. The cross-sectional shape of the positioning space 3232 matches the cross-sectional shape of the screw, and the tip of the screw points toward the first channel 3221.
The screw tightening device 33 is a full-automatic screwing machine, and the number of the screw tightening devices 33 is two.
The position sensor 40 includes a transmitter 41 and a receiver 42 connected to the transmitter 41. The transmitter 41 is disposed on the extension table 112, the receiver 42 is embedded in the limiting plate 113 and disposed opposite to the transmitter 41, and the receiver 42 is respectively connected to the servo motor 22 and the screw tightening device 33.
Specifically, the receiver 42 and the servo motor 22 may be electrically connected or communicatively connected, and the purpose of the receiver 42 is to send an operating signal to the servo motor 22.
The working process of the automatic assembly line 100 for the door frame connecting rod provided by the invention comprises the following steps:
step S10, before the door frame link automatic assembly line 100 starts to work, the push rod of the screw tightening device 33 is retracted to the side of the positioning space 3232 away from the first passage 3221;
step S20, placing a sufficient number of screws into the storage space 3231, starting the transportation device 20 and the charging barrel 31, and placing a door frame profile on the side of the feeding port 101 facing the transportation device 20;
step S30, the door frame profile moves along with the transportation device 20, when the end of the door frame profile away from the material inlet moves to a position between the emitter 41 and the receiver 42, the door frame profile obstructs the connection between the emitter 41 and the receiver 42, at this time, the receiver 42 sends a stop signal to the servo motor 22, and the door frame profile stays there to be processed;
step S40, at the same time, the receiver 42 sends a working signal to the screw tightening device 33, the push rod of the screw tightening device 33 runs along the positioning space 3232 to the first channel 3221, a screw is pushed into the first channel 3221 in the positioning space 3232, so that the screw is pushed into the mounting hole of the mounting plate 202, the mounting plate 202 is pushed out to be in contact with the doorframe profile through the second channel 3222, and finally the screw is tightened to the doorframe profile, thereby completing the installation of the single mounting plate 202;
step S50, after the installation is completed, the servo motor 22 continues to work, and the installed installation plate 202 is transported to the discharge port 102 for further processing;
and step S60, repeating the steps S10 to S50.
