Description

Technical Field

[0001] The invention relates to the technical field of aluminum spacer bar processing equipment, and in particular to a fully automatic bending angle measuring device for aluminum spacer bars. Background Art

[0002] Aluminum spacers are structural products made of aluminum or aluminum alloy materials to form a cavity, used to fill desiccant, isolate hollow glass sheets, and play a supporting role.

[0003] After searching:

[0004] Document 1, a Chinese patent with announcement number CN 219130428 U discloses a hollow glass aluminum spacer bending machine head, which applies extrusion force to the limit guide roller by using a screw, a rotating handle and a sliding rod instead of a spring structure, converting the elastic force into a rigid force, avoiding the limit guide roller from deviating when the aluminum strip is bent, thereby causing the aluminum strip to deviate, and ensuring the accuracy of the aluminum strip when bending; it includes a base, a support platform, a pushing mechanism and a bending mechanism, the support platform is fixed to the top of the base, the pushing mechanism is installed on the left side of the top of the base, and the pushing mechanism is used to push the aluminum strip to move on the support platform, the bending mechanism is installed on the right side of the top of the base, the bending mechanism is used to bend the aluminum strip, and also includes two groups of fixed plates, an adjustment mechanism, two groups of moving blocks, multiple groups of fixed blocks and multiple groups of limit guide rollers, and the two groups of fixed plates are symmetrically fixed on the front and rear sides of the left side of the top of the base respectively;

[0005] Document 2, a Chinese patent with announcement number CN 118274745 B discloses a bending angle measuring device for a bending part, which controls the operation of a servo motor and a laser ranging module through a touch screen controller, records the time between the start time of the laser ranging module and the time when the measurement data changes significantly, and then uses the product of the time and the angular velocity of the servo motor to obtain the angle of the bending part of the bending part. The entire non-contact measurement process avoids difficult data processing and calculation processes, effectively reduces the operational difficulty of the measurement process, and reduces the technical threshold for use, thereby better meeting the use and maintenance needs of small and medium-sized enterprises;

[0006] The inventor has found that in Document 1, the bending of the workpiece is achieved by the cooperation of a fixed bending roller and a movable bending roller. However, due to the limitation of the fixed bending roller, the workpiece will fit the side of the fixed bending roller to form an arc surface during the bending process, and the vertical angle surface cannot be formed, which affects the subsequent installation and the workpiece after bending cannot be detected. In Document 2, although the workpiece angle can be measured, the workpiece is directly placed on the supporting plate during the measurement process, which is only applicable to L-shaped workpieces of a certain specification. For rectangular or square workpieces, it cannot be stably placed on the supporting plate. At the same time, when the device measures rectangular or square workpieces, due to inaccurate placement, its laser ranging module may detect more than two groups of edges, thereby affecting the measurement accuracy. At the same time, when measuring multiple measurement points of a rectangular or square workpiece, it is necessary to continuously adjust the position of the workpiece manually, which is not convenient to use. Therefore, the present invention proposes a fully automatic bending angle measurement device for aluminum spacers. Summary of the invention

When the laser rangefinder 16 is turned on, the horizontal part of the workpiece will block the laser. At this time, the data from the horizontal part of the workpiece to the laser rangefinder 16 can be obtained, and the data is transmitted to the touch control screen 20. The touch control screen 20 controls the second motor 21 to rotate, so that the measuring plate 17 drives the laser rangefinder 16 to rotate upward until the laser of the laser rangefinder 16 is blocked by the vertical end of the workpiece. At this time, the second set of data is obtained and transmitted to the touch control screen 20. When the second set of data is obtained, the operation of the second motor 21 is stopped. The bending angle of the workpiece can be obtained by multiplying the time between the two sets of data by the rotation angle of the second motor 21, thereby realizing rapid measurement.

It should be noted that in order to avoid the support clamp 29 from supporting and deforming the workpiece from the inside, affecting the measurement of the subsequent bending part, a pressure sensor can be embedded in the support clamp 29 to monitor the pressure between the workpiece and the support clamp 29 to avoid deformation of the workpiece. Through the fifth motor 44, the conical teeth 53 can be driven to rotate conveniently, thereby driving the threaded rod 52 to rotate. Due to the threaded connection between the threaded rod 52 and the threaded sleeve 51, the connecting seat 58 can be extended to adjust the distance between the connecting seat 58 and the fixed seat 26.

[0063] The present invention provides a fully automatic bending angle measuring device for aluminum spacers, and the specific working principle is as follows: during normal use, the device is powered on, and the height of the feed roller 36 and the positioning plate 13 are adjusted according to the thickness of the workpiece, the workpiece passes through the feed roller 36 and is attached to the side of the drive box 8, and then the first motor 6 is operated. The first motor 6 drives the feed roller 36 to rotate through the first sprocket 7 and the first chain to realize the transportation of the workpiece. The workpiece passes through the bending plate 37 and moves to the right side of the workbench 2. During the transportation process, the guide roller on the inner side of the clamping plate 4 can be attached to the side of the workpiece to play a role in positioning and guiding. After the workpiece is transported to the specified length, the drive cylinder 54 is operated, and the drive cylinder 54 drives the drive The shaft 9 moves, and the driving shaft 9 drives the bending part 10 to move until the bending part 10 contacts the surface of the workpiece, and then the bending cylinder 34 is operated, and the bending cylinder 34 drives the bending plate 37 to rotate upward, and the bending plate 37 pushes the workpiece to move upward around the bending part 10 until the bending plate 37 is in a vertical state. At this time, the bending of the workpiece is completed, and then the bending plate 37 is reset to move the workpiece. When the bent portion of the workpiece moves to the right side of the positioning member, the sixth motor 49 can be operated at this time, and the sixth motor 49 drives the active gear 39 to rotate, and cooperates with the driven gear 38 to drive the fixed column 11 to rotate, and the fixed column 11 drives the positioning plate 13 to move until the positioning plate 13 fits the horizontal part of the workpiece. The third motor 33 can be operated, and the third motor 33 drives the threaded rod 52 to rotate, and drives the positioning seat 32 to move through the threaded seat 31, and the positioning seat 32 moves along the guide rail 15, so that the positioning plate 13 drives the bent workpiece to move to the right. It should be noted that the measuring plate 17 is in an inclined state, that is, the laser rangefinder 16 is in a state directly in front of the horizontal end of the workpiece. When the laser rangefinder 16 is turned on, the horizontal part of the workpiece will block the laser until the horizontal part of the workpiece can block the laser of the laser rangefinder 16, and then the laser rangefinder 16 is turned on. Since the horizontal part of the workpiece will block the laser, the data from the horizontal part of the workpiece to the laser rangefinder 16 can be obtained at this time, and the data can be transmitted to the laser rangefinder 16. The data is transmitted to the touch control screen 20, and the touch control screen 20 controls the second motor 21 to rotate, so that the measuring plate 17 drives the laser rangefinder 16 to rotate upward until the laser of the laser rangefinder 16 is blocked by the vertical end of the workpiece. At this time, the second set of data is obtained and transmitted to the touch control screen 20. When the second set of data is obtained, the operation of the second motor 21 is stopped, and the bending angle of the workpiece can be obtained by multiplying the time length between the two sets of data by the rotation angle of the second motor 21, so as to achieve rapid measurement, and then continue to operate the sixth motor 49 to make the workpiece fall from the workbench 2. After the bending angle of the workpiece is measured, the measuring plate 17, i.e., the laser rangefinder 16, needs to be reset, and then wait for the next measurement;

[0064] When it is necessary to measure a rectangular or square workpiece, the first bolt 25 is unscrewed, and then the fixing seat 26 is rotated 180° and then fixed with the first bolt 25. Then, according to the specifications of the workpiece, the distance between the connecting seat 58 and the frame 1 is adjusted so that when the workpiece is rotated, it will not collide with the frame 1. The fifth motor 44 drives the threaded rod 52 to rotate through the conical teeth 53. The rotation of the threaded rod 52 will cause the threaded sleeve 51 to expand and contract outward, thereby driving the connecting seat 58 to move to achieve adjustment. Then, the positioning cylinder 27 is extended and contracted to make the support clamp 29 support the workpiece from the inside. Due to the limitation of the support clamp 29, the workpiece will be horizontal with the fixing plate 18. Before measurement, the measuring plate 17 is in a horizontal state, that is, when the laser rangefinder 16 is started, the emitted laser is blocked by the horizontal part of the workpiece. At this time, the first set of data is directly obtained, and then the second motor 21 is operated to drive the measuring plate 17 and The laser rangefinder 16 rotates until the second set of data is obtained. At this time, the second motor 21 is stopped to complete the angle measurement of the first set of bends of the workpiece. Then, the position of the workpiece is adjusted by the rotation of the fourth motor 43, and the height of the workpiece after rotation is adjusted by the extension and contraction of the positioning cylinder 27. The position of the connecting seat 58 is adjusted by the operation of the fifth motor 44, and then the position of the workpiece is adjusted so that the horizontal part of the second set of bends is located directly behind the laser rangefinder 16. Then the measurement can be carried out. The above operations are performed in sequence to complete the measurement of the four sets of bends of the workpiece. It should be noted that the electronic devices used in this technical solution are all existing products. The specific connection and control sequence should refer to the working principle of this technical solution and the working sequence between the electrical components. The detailed connection means are well known in the art. This technical solution mainly introduces the working principle and process, and no longer explains the electrical control.
