Description

Technical Field

[0001] The present invention relates to the field of shutter blade installation, and in particular to a numerically controlled shutter connection and assembly machine and a shutter connection and assembly method. Background Art

[0002] The shutters are composed of an outer frame and several blades. When assembling, several blades need to be placed in the outer frame, holes are drilled on the edge of the outer frame, and then the blades are connected to the outer frame with bolts through the holes to complete the assembly of the shutters.

[0003] In order to achieve quick and accurate assembly, those skilled in the art began to develop corresponding assembly equipment. By fixing the frame, the blades are placed on the distance adjustment module, and the electric drilling machine and electric screwdriver are used to drill holes and screw in screws respectively. For example, the invention patent with patent application number 2023108737655 discloses a CNC blinds assembly machine equipped with an equidistant adjustment module, which can automatically adjust the spacing of each blade at an equal distance, and support and position the ends of the blades to facilitate accurate processing and improve the installation accuracy of the blades. It includes a frame, and a left longitudinal beam and a right longitudinal beam are provided on the left and right sides of the frame. A variable distance station module is provided between the left longitudinal beam and the right longitudinal beam, and the variable distance station module includes a number of station brackets that can support the blades; the left longitudinal beam and the right longitudinal beam are both slidably connected with a head and a clamping mechanism. The variable-distance workstation module includes a scissor-fork linkage and several movable workstation seats. The scissor-fork linkage is composed of several movable X-shaped scissor-fork structures hinged end to end, with two short rods hinged at each end. The other ends of the two short rods are hinged together. However, a drawback of this technology is that because the scissor-fork structure is composed of two rods hinged together by a pin, there is inevitably a gap between the pin and the shaft hole. When several scissor-fork mechanisms are hinged end to end, a certain gap error will be generated, resulting in uneven distribution of the blades. Ultimately, the blades in the assembled blinds are unevenly assembled, resulting in poor assembly quality. Summary of the Invention

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] In the description of the invention, it should be understood that the terms "front," "rear," "upper," "lower," "left," "right," and the like, indicating directions or positions, are based on the directions or positions shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific direction, and therefore should not be construed as limiting the invention. The invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] like Figure 1 As shown, this embodiment discloses a CNC blind connection and assembly machine, comprising a frame 1, a left longitudinal beam 2, a right longitudinal beam 3, a machine head 4, a frame pressing and feeding mechanism 5, a blade bracket mechanism 6, and an auxiliary vertical plate 7. The left longitudinal beam 2 and the right longitudinal beam 3 are symmetrically mounted on the left and right sides of the frame 1, longitudinally distributed front and back.

[0046] There are two heads, which are fixed symmetrically on the left longitudinal beam 2 and the right longitudinal beam 3 respectively. Figure 2 As shown, each machine head 4 includes a machine head base 41, which is mounted on the outer side of the corresponding beam body via a bolt assembly. An X-direction sliding assembly is mounted on the machine head base 41, and a Z-direction sliding assembly is mounted on the slider of the X-direction sliding assembly. An electric drill 42 and an electric screwdriver 43 are mounted on the slider of the Z-direction sliding assembly. The Z-direction sliding assembly and the X-direction sliding assembly are conventional automatic control movement devices in numerical control equipment. They enable the mechanism to move back and forth along the Z-direction (vertical) and X-direction (front-back longitudinal) directions, which is a conventional technical means. This enables the electric drill 42 and the electric screwdriver 43 to perform drilling and screwdriving operations, respectively. Also mounted on the machine head base 41 is a machine head connecting plate 44. A cross plate is mounted on the top of the machine head connecting plate 44. Two second lifting cylinders 45 and one third lifting cylinder 46 are mounted on the bottom surface of the cross plate. The movable ends of the second and third lifting cylinders 45 and 46 face downward and are equipped with compression blocks. The two second lifting cylinders 45 are used to compress the frame, and the one third lifting cylinder 46 is used to compress the blade.

[0047] In this embodiment, the top surfaces of the left longitudinal beam 2 and the right longitudinal beam 3 are equipped with two frame pressing and feeding mechanisms 5. The two frame pressing and feeding mechanisms 5 located on the same beam body are located at the front and rear of the machine head respectively. Figure 3As shown, each frame pressing and feeding mechanism 5 includes a feeding base plate 51, a feeding support plate 52, a feeding vertical plate 53 and a first lifting cylinder 54. In the frame pressing and feeding mechanism installed on the left longitudinal beam 2, the feeding base plate 51 is connected to the outer side surface of the beam body of the left longitudinal beam 2 through a linear guide pair; in the frame pressing and feeding mechanism installed on the right longitudinal beam 3, the feeding base plate 51 is connected to the outer side surface of the beam body of the right longitudinal beam 3 through a linear guide pair. The feeding support plate 52 is laterally fixed to the top surface of the feeding base plate 51 by a bolt assembly to ensure that the feeding support plate 52 is located above the beam body, the feeding vertical plate 53 is installed on the feeding support plate 52, and the first lifting cylinder 54 is installed on the front side of the feeding vertical plate 53 so that the movable end of the first lifting cylinder 54 faces downward and is fixed with a pressing block, which can cooperate with the feeding support plate 52 to press the frame together. A plurality of pads 8 for supporting the frame are provided on the top surfaces of the left longitudinal beam 2 and the right longitudinal beam 3. The top surfaces of the pads 8 are at the same height as the top surface of the feeding support plate 52, ensuring that the frame can be placed horizontally.

[0048] To ensure synchronous movement, the two frame compression and feeding mechanisms 5 located on the same side have their feed base plates 51 connected as a whole via a connecting rod. A drive motor 55 is mounted on the feed base plate of one of the frame compression and feeding mechanisms 5. The output end of the drive motor 55 is mounted with a drive gear, and the outer side of the beam body is mounted with a rack that can mesh with the drive gear. The drive motor 55 is a servo motor that can accurately drive the displacement of the frame compression and feeding mechanism 5. In this embodiment, the first lifting cylinder 54, the second lifting cylinder 45, and the third lifting cylinder 46 can be, but are not limited to, electric lifting cylinders or hydraulic lifting cylinders.

[0049] like Figure 4 As shown, the blade support mechanism 6 is installed between the left longitudinal beam 2 and the right longitudinal beam 3 and is longitudinally distributed front to back. The blade support mechanism 6 includes a base frame 61, a support frame 62, and two symmetrically distributed support risers 63. The base frame 61 and the support frame 62 are both rectangular frames. The base frame 61 is slidably connected to the frame 1 via a linear guide pair. The top of the base frame 61 is connected to the support frame 62 via multiple lifting devices to achieve the lifting movement of the support frame 62. The two support risers 63 are fixed to the support frame 62 symmetrically. The top surface of the support risers 63 is a louver positioning mold 66. The louver positioning mold 66 has a plurality of evenly distributed positioning grooves 64. The positioning grooves 64 are opposite to each other to ensure stable engagement and support of the blades. A reciprocating drive device 65 is also installed on the frame 1. The output end of the reciprocating drive device 65 is connected to the base frame 61. In this embodiment, the reciprocating drive device is, but is not limited to, a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, or an electric screw. The reciprocating drive device realizes the back and forth movement of the blade support mechanism 6.

[0050] like Figure 5As shown, the two auxiliary vertical plates 7 are respectively connected to the inner side surfaces of the left longitudinal beam 2 and the right longitudinal beam 3 by vertical sliding through a linear guide pair. The inner side surface of the beam body is also fixed with a fourth lifting cylinder 9. The movable end of the fourth lifting cylinder 9 is connected to the auxiliary vertical plate 7. The lifting and lowering of the auxiliary vertical plate 7 is controlled by the fourth lifting cylinder 9. On the top surface of the auxiliary vertical plate 7 is an auxiliary positioning mold 71. The auxiliary positioning mold 71 is provided with positioning grooves of the same specifications (the number, size spacing and shape are the same) as the louver positioning mold 66.

[0051] Based on the CNC blind connection and assembly machine disclosed in this embodiment, this embodiment also discloses a blind connection and assembly method, including the following steps:

[0052] S1. First, place the first blade into the first row of positioning grooves of the louver positioning mold on the vertical plate of the bracket in the blade bracket mechanism and align the blade so that the first blade is located at the corresponding position of the machine head. The system automatically records the position of the louver.

[0053] S2. Multiple blades are evenly spaced and clamped into the positioning grooves on the bracket vertical plate of the blade bracket mechanism, and the frames are placed on the right side of the positioning plate of the slave table for positioning, and then the frames are pressed by the frame pressing feeding mechanism on the left and right sides;

[0054] By controlling the fourth lifting cylinder 9 to control the auxiliary vertical plate to rise, the positioning grooves of the auxiliary positioning mold of the auxiliary vertical plate support the two ends of the blade, thereby supporting the two ends of the blade and ensuring the stability of the blade;

[0055] In this step, the frame pressing and feeding mechanism presses the frame by placing the frame on the top surface of the feeding support plate 52, and controlling the first lifting cylinder 54 to descend so that the pressing block can cooperate with the feeding support plate 52 to press the frame together;

[0056] S3, drilling holes and screwing the frame and blades through the machine head, so that the first blade on the work station is connected to the left and right frames;

[0057] In this step, in order to ensure the stability of the blade, the third lifting cylinder 46 can be controlled to descend, and the pressing block can be used to press the blade;

[0058] S4, the auxiliary vertical plate is controlled to descend by the fourth lifting cylinder 9, so that the positioning grooves of the auxiliary positioning mold are separated from the blade. At this time, the reciprocating drive device and the drive motor respectively control the blade bracket mechanism and the frame pressing and feeding mechanism to move forward at the same speed;

[0059] When the bracket riser of the blade bracket mechanism carries the blade and moves forward by a distance d (where d is the distance between adjacent positioning grooves of the louver positioning mold. In this embodiment, the distance d between adjacent positioning grooves 64 is 60 mm), the auxiliary riser is controlled to rise, and all the blades to be connected and assembled are supported by the positioning grooves of the auxiliary positioning mold. The bracket riser is controlled to fall, so that the positioning grooves of the louver positioning mold of the bracket riser are separated from the blades.

[0060] When the frame pressing and feeding mechanism carries the frame forward and moves D, it stops (wherein D is the distance between the blades. In this embodiment, D can be 60, 80, 100 mm, etc., and cannot be less than the distance d between the positioning grooves). At the same time, the bracket riser is controlled to rise so that the blade to be connected and assembled is re-engaged and supported in the positioning groove of the louver positioning mold. At this time, the second blade is located at the work station corresponding to the head of the machine;

[0061] S5. Use the machine head to drill holes and screw the frame and blades to connect the blades on the workstation to the left and right frames;

[0062] In this step, in order to ensure the stability of the blade, the third lifting cylinder 46 can be controlled to descend, and the pressing block can be used to press the blade;

[0063] S6. The bracket riser 63 is controlled to descend by the lifting device so that the positioning grooves of the louver positioning mold of the bracket riser are separated from the blades. The frame pressing and feeding mechanism is controlled to release the frame. At the same time, the second lifting cylinder 45 is controlled to descend to press the frame against the pad.

[0064] The frame pressing and feeding mechanism is controlled to move backward a distance D to return to the origin, and then the first lifting cylinder 54 is lowered to re-press the frame, while the second lifting cylinder 45 is controlled to rise to release its pressure on the frame, and the frame pressing and feeding mechanism 5 drives the frame to move forward a distance D;

[0065] The bracket vertical plate is controlled to move backward a distance d to return to the origin, and then the bracket vertical plate is controlled to rise so that the blade to be connected and assembled is re-engaged and supported in the positioning groove; then the auxiliary vertical plate is controlled to descend so that the positioning grooves of the auxiliary vertical plate are separated from the blade, and the bracket vertical plate is controlled to move forward a distance d to allow the next blade to be delivered to the work station corresponding to the head of the machine, and the auxiliary vertical plate is controlled to rise so that all the blades to be connected and assembled are engaged and supported through the positioning grooves of the auxiliary positioning mold;

[0066] S7. Repeat steps S5-S6 to assemble and connect the blades one by one to the frame.

[0067] By the shutter connection and assembly method described in the present invention, multiple blades are evenly spaced and clamped in the positioning grooves 64 on the bracket vertical plate 63 in the blade bracket mechanism 6, and the frame is pressed by the frame pressing and feeding mechanism 5 on the left and right sides; the head station is fixed in an unchanged position, and the blades are accurately delivered to the head station by controlling the movement of the blade bracket mechanism 6, and the frame position is adjusted by controlling the frame pressing and feeding mechanism 5, and the blade installation spacing is accurately controlled to ensure that the blades are accurately installed on the frame. This can not only ensure the uniformity of the blade installation in the shutter, but also accurately adjust the blade installation spacing at any time.

When the frame pressing and feeding mechanism moves forward with the frame by D, it stops, where D is the distance between the blades, D≥d; at the same time, the bracket riser is controlled to rise so that the blades to be connected and assembled are re-engaged and supported in the positioning grooves in the louver positioning mold. At this time, the second blade is located at the corresponding position of the machine head; S5. Use the machine head to drill holes and screw the frame and blades to connect the blades on the workstation to the left and right frames; S6. Control the bracket riser to descend so that the positioning grooves of the louver positioning mold of the bracket riser are separated from the blades, and control the frame to press the feeding mechanism and release the frame; Control the frame to press the feeding mechanism and move it backward a distance D to return to the origin, then clamp the frame and drive the frame to move forward a distance D; control the bracket vertical plate to move backward a distance d to return to the origin, then control the bracket vertical plate to rise so that the blade to be connected and assembled is re-engaged and supported in the positioning groove; The auxiliary vertical plate is controlled to descend so that the positioning grooves of the auxiliary vertical plate are separated from the blade, and the bracket vertical plate is controlled to move forward a distance d so that the next blade is sent to the corresponding position of the head of the die, and the auxiliary vertical plate is controlled to rise so that all the blades to be connected and assembled are clamped and supported through the positioning grooves of the auxiliary positioning mold; S7. Repeat steps S5-S6 to assemble and connect the blades one by one to the frame.
