Description

Technical Field

[0001] The invention relates to the technical field of conveying, in particular to a single-side crack detection and feeding structure used for the production of hollow glass doors of refrigeration equipment. Background Art

[0002] Since the characteristics of glass doors are determined by the characteristics of the glass itself, when tempered transparent glass is used, the door leaf has a transparent function, and when frosted glass is used, it has a semi-transparent function, so glass doors are widely used; however, after the glass is produced, when the glass door panel is installed in the door frame, cracks may appear on the glass due to construction. Cracks pose a potential threat to the integrity and safety of the glass structure. As the cracks expand, the glass will break, causing accidents, so it is necessary to detect glass cracks;

[0003] For example, the invention of the existing patent application No.: 201610291754.6 provides a tempered glass inspection platform, which can solve the problem of low inspection efficiency caused by the need for manual handling during the existing tempered glass surface inspection. It includes a bottom frame, a detection frame is arranged on the upper part of the bottom frame, the detection frame includes a frame bottom plate and a frame arranged around the frame bottom plate, a black curtain is fixed on the upper surface of the frame bottom plate of the detection frame, and a detection light source is arranged in the detection frame.

[0004] Taking the above-mentioned detection equipment as an example, in the existing glass crack detection process, most of the tests are performed on one side of the glass. However, for products such as hollow glass doors, the two pieces of glass are independent, so both glasses must be tested, which requires the staff to turn over the hollow glass door during the detection process. This is not only time-consuming and labor-intensive, but also during the flipping process of the hollow glass door, even if it is done by mechanical equipment, it is easy to cause secondary damage.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: Figure 1-Figure 14As shown, the present invention provides a technical solution of a single-sided crack detection feeding structure for the production of hollow glass doors of refrigeration equipment, including a feeding structure 1 and a glass door 2, a detection structure 3 is installed on the feeding structure 1, and the detection structure 3 includes an I-shaped frame 333 and two equipment mounting plates 31, one of which is arranged at the top of the glass door 2, and the other is arranged at the bottom of the glass door 2, and ultrasonic detection devices 32 are slidably installed on the side of the two equipment mounting plates 31 close to the glass door 2, and transverse guide rails 37 are slidably installed on the sides of the two ultrasonic detection devices 32 away from each other, and fixed vertical plates 33 are fixedly installed on the sides of the two ultrasonic detection devices 32 away from each other. 10. A hydraulic cylinder 1 38 is fixedly installed on the side of the bottom transverse guide rail 37 away from the ultrasonic detection equipment 32, and a compression telescopic rod 3 39 is fixedly installed on the top of the bottom transverse guide rail 37, and the piston end of the compression telescopic rod 39 is fixedly connected to the bottom fixed vertical plate 310; a hydraulic telescopic rod 1 317 is fixedly connected to the side of the top transverse guide rail 37 away from the ultrasonic detection equipment 32, a hydraulic transmission assembly is arranged between the hydraulic telescopic rod 1 317 and the hydraulic cylinder 1 38, a hydraulic telescopic rod 2 320 is arranged at the bottom of the top transverse guide rail 37, the hydraulic telescopic rod 2 320 is fixedly connected to the top fixed vertical plate 310, and a hydraulic control assembly is arranged between the hydraulic telescopic rod 2 320 and the compression telescopic rod 39.

[0036] In the present application, the glass door 2 includes a door frame 21 and an upper glass plate 22 and a lower glass 23 installed inside the door frame 21. This is a common hollow glass door structure, and the upper glass plate 22 and the lower glass 23 can be made of heat-resistant glass, so that the glass door 2 is suitable for use in refrigeration equipment, heating equipment and other equipment with a large temperature difference between the inside and outside. This is a public technology and will not be described in detail here.

[0037] The feeding structure 1 is composed of two conveying devices 11, a mounting frame 12 fixedly installed on the side of the conveying device 11 away from the glass door 2, a plurality of legs 13 fixedly installed at the bottom of the mounting frame 12, and a plurality of connecting rods 14 fixedly installed between the two conveying devices 11. The glass door 2 is placed on the top of the feeding structure 1, so that the two sides of the bottom of the door frame 21 are supported by the two conveying devices 11. The two conveying devices 11 work synchronously to convey the door frame 21, so as to convey the glass door 2; and a plurality of supporting rods 15 are fixedly installed on the top of the mounting frame 12, and the outer sides of the plurality of supporting rods 15 are rotatably sleeved with limiting rollers 16, and the symmetrically arranged plurality of limiting rollers 16 form a channel to control the movement trajectory of the glass door 2 and ensure the horizontal movement of the glass door 2.

[0038] The feeding structure 1 and the detection structure 3 are controlled to work by a human-machine interaction device, which is a known technology and will not be discussed in detail here.

[0039] A detection structure 3 is installed on the feeding structure 1. Two equipment installation plates 31 in the detection structure 3 are respectively arranged at the top and bottom of the glass door 2. A fixing frame 4 328 is fixedly connected to one side of the equipment installation plate 31 at the bottom. A pressure sensor 330 is fixedly installed on the piston end of the electric push rod 329 fixedly connected to the top of the fixing frame 4 328. Fig.11 As shown, the electric push rod 329 is controlled to work regularly. The electric push rod 329 pushes the pressure sensor 330 to move upward to the movement trajectory of the glass door 2. The pressure sensor 330 stops the glass door 2, so that the glass door 2 is stopped at the detection position inside the detection structure 3. When one side of the pressure sensor 330 is pressed by the glass door 2, the pressure detected by the pressure sensor 330 increases. The human-computer interaction device electrically connected to the pressure sensor 330 controls the feeding structure 1 to stop working, and controls the detection structure 3 to work to detect the glass door 2.

[0040] Since the ultrasonic detection device 32 is arranged on one side of the two device mounting plates 31 close to the glass door 2, four sliding grooves 1 34 and two sliding grooves 2 35 are provided on the side of the device mounting plates 31 close to the ultrasonic detection device 32, and the longitudinal sliding grooves 2 35 penetrate the four transverse sliding grooves 1 34, such as Figure 5 As shown, two sliding balls 33 fixedly connected to the ultrasonic detection device 32 are arranged inside one of the sliding grooves 35. Under the action of the two sliding grooves 35, the four sliding grooves 34 and the two sliding balls 33, the ultrasonic detection device 32 and the device mounting plate 31 form a sliding mounting relationship;

[0041] When the sliding ball 33 is located inside the sliding groove 2 35, since the ultrasonic detection equipment 32 is fixedly connected to the side of the transverse guide rail 37, the sliding block 36 is arranged inside the adjacent transverse guide rail 37, so that a sliding connection relationship is formed between the ultrasonic detection equipment 32 and the transverse guide rail 37, and the two move forward and backward synchronously. At the same time, the ultrasonic detection equipment 32 can move left and right under the restriction of the transverse guide rail 37, so that the two sliding balls 33 move left and right inside the sliding groove 2 35 and align with the two sliding grooves 1 34 on the left or with the two sliding grooves 1 34 on the right. After that, the detection structure 3 can be controlled to work, so that the transverse guide rail 37 drives the ultrasonic detection equipment 32 to move forward and backward, and the sliding ball 33 moves back and forth inside the sliding groove 1 34, so that the ultrasonic detection equipment 32 can move on the equipment mounting plate 31 along the U-shaped track.

[0042] When the detection structure 3 is working to detect the glass door 2, the hydraulic cylinder 1 38 in the detection structure 3 works first, and the hydraulic cylinder 1 38 fixedly installed on the top of one of the connecting rods 14 works and extends to push the bottom transverse guide rail 37 fixedly installed on the piston end to move forward, and the forward-moving transverse guide rail 37 drives the ultrasonic detection equipment 32 to move forward; because the T-shaped block 314 in the hydraulic transmission assembly is fixedly connected to the bottom transverse guide rail 37, the bottom transverse guide rail 37 drives the T-shaped block 314 to move forward when it moves, and a telescopic liquid storage part 313 is fixedly connected to one side of the T-shaped block 314, and one end of the telescopic liquid storage part 313 passes through the sliding groove 312 formed on the bottom equipment mounting plate 31 and then extends into the interior of the storage box 315, such as Fig. 9 As shown, one end of the telescopic liquid storage member 313 is fixedly connected to the storage box 315, so the T-shaped block 314 will move inside the sliding groove 312 during the movement, and the T-shaped block 314 squeezes the telescopic liquid storage member 313 to shrink the telescopic liquid storage member 313, so that the internal hydraulic pressure of the part of the telescopic liquid storage member 313 located inside the storage box 315 rises; and the guide tube 2 316 in the hydraulic transmission assembly is fixedly connected between the telescopic liquid storage member 313 and the hydraulic telescopic rod 1 317, so that the internal medium of the telescopic liquid storage member 313 enters the hydraulic telescopic rod 1 317 through the guide tube 2 316, and the internal hydraulic pressure of the hydraulic telescopic rod 1 317 rises. Since a plurality of fixed bent rods 332 are fixedly connected between the top equipment mounting plate 31 and one of the mounting frames 12, the position of the top equipment mounting plate 31 cannot move, and a fixed frame 1 318 is fixedly connected to one side of the top equipment mounting plate 31, and the fixed frame 1 318 is fixedly connected to the hydraulic telescopic rod 1 317, as shown in FIG. Fig.11 As shown, the outer wall of the hydraulic telescopic rod 317 cannot move. Therefore, when the hydraulic pressure inside the hydraulic telescopic rod 317 increases, the hydraulic telescopic rod 317 extends and pushes the top transverse guide rail 37 fixed at the piston end to move backward, and the transverse guide rail 37 drives the ultrasonic detection device 32 to move backward;

[0043] Since the top ultrasonic detection device 32 is set at the front right side of the top of the glass door 2, the top ultrasonic detection device 32 inspects the top right side of the glass door 2, and the bottom ultrasonic detection device 32 is set at the rear left side of the bottom of the glass door 2, the bottom ultrasonic detection device 32 inspects the bottom left side of the glass door 2.

[0044] Since the compression telescopic rod 39 is fixedly mounted on the top of the bottom transverse guide rail 37, and the fixing frame 331 fixedly mounted on one end of the hydraulic telescopic rod 2 320 is fixedly mounted together with the top transverse guide rail 37, the compression telescopic rod 39 and the hydraulic telescopic rod 2 320 both move synchronously with the transverse guide rail 37 on which they are mounted;

[0045] When the hydraulic cylinder 38 is extended to the limit, the double-axis pneumatic cylinder 323 in the hydraulic control assembly is controlled to work. Since the two piston ends of the double-axis pneumatic cylinder 323 are fixedly installed with piston rods 324, as shown in FIG. Fig.14 As shown, a second fixing frame 327 is fixedly installed between the piston box 325 slidably sleeved on the outer side of the piston rod 324 and the second supporting spring 322, so that the piston box 325 cannot move. The working dual-axis pneumatic cylinder 323 pushes the piston rod 324 to move inside the piston box 325. The movement of the piston rod 324 squeezes the liquid inside the piston box 325, so that the internal hydraulic pressure of the piston box 325 increases; and the two piston boxes 325 are fixedly connected to the side away from the dual-axis pneumatic cylinder 323 with a hose 326, one end of the guide pipe 321 fixedly connected to one of the hoses 326 is fixedly connected to the hydraulic telescopic rod 2 320, as shown in FIG. Figure 6 As shown, one end of another hose 326 is fixedly connected to the guide tube 1 311, and the other end is fixedly connected to the compression and telescopic rod 3 39, and the hose 326 is a hose that does not affect the internal conduction after a certain deformation, and the compression and telescopic rod 3 39 and the hydraulic telescopic rod 2 320 reciprocate back and forth, so the hose 326 will not be affected by the movement of the compression and telescopic rod 3 39 and the hydraulic telescopic rod 2 320; therefore, after the internal hydraulic pressure of the piston box 325 increases, the internal medium of the piston box 325 enters the compression and telescopic rod 3 39 through the hose 326 and the guide tube 1 311 installed therein, so that the compression and telescopic rod 3 39 extends and pushes the fixed end fixedly installed at one end. The vertical plate 310 moves rightward, and the fixed vertical plate 310 drives the fixedly connected bottom ultrasonic detection device 32 to move rightward. When the compression telescopic rod 39 is extended to the limit, the bottom ultrasonic detection device 32 moves rightward to the front right side of the bottom of the glass door 2. The medium inside the other piston box 325 enters the inside of the hydraulic telescopic rod 2 320 through the hose 326 and the guide pipe 3 321 installed therein. The hydraulic telescopic rod 2 320 extends and pushes the fixed vertical plate 310 fixedly installed at the piston end to move leftward. The fixed vertical plate 310 drives the top ultrasonic detection device 32 to move leftward, so that the top ultrasonic detection device 32 moves leftward to the rear left side of the top of the glass door 2.

[0046] Then, the hydraulic cylinder 38 is controlled to work and contract, and the hydraulic cylinder 38 drives the bottom transverse guide rail 37 to reset, and the transverse guide rail 37 drives the bottom ultrasonic detection device 32 to move backward to detect the right side of the bottom of the glass door 2, and the bottom transverse guide rail 37 drives the T-shaped block 314 to reset, and the telescopic liquid storage part 313 loses pressure, and the internal hydraulic pressure of the hydraulic telescopic rod 317 drops, and there are two supporting springs 319 fixedly connected between the fixed frame 318 and the upper transverse guide rail 37, at this time, the supporting spring 319 rebounds to drive the top transverse guide rail 37 to reset, and the top transverse guide rail 37 drives the top ultrasonic detection device 32 to detect the top left side of the glass door 2;

[0047] When the hydraulic cylinder 1 38 has finished working, the double-axis pneumatic cylinder 323 is controlled to work and retract, the hydraulic pressure inside the piston box 325 is restored, the telescopic rod 3 39 is compressed and retracted, and the telescopic rod 3 39 drives the bottom fixed vertical plate 310 to move left and reset, and the bottom ultrasonic detection equipment 32 moves left and reset; the hydraulic telescopic rod 2 320 is compressed, and the hydraulic telescopic rod 2 320 drives the top fixed vertical plate 310 to move right and reset, and the top ultrasonic detection equipment 32 moves right and reset. At this time, the detection structure 3 returns to its initial state, and the surface crack detection work of the upper glass plate 22 at the top of the inner cavity of the door frame 21 and the lower glass 23 at the bottom of the inner cavity is completed.

[0048] The detection structure 3 in the present application can simultaneously detect surface cracks on the upper glass plate 22 and the lower glass 23 inside the door frame 21, and during the detection process, the ultrasonic detection devices 32 symmetrically arranged at the two diagonal positions of the glass door 2 are installed with a preset U-shaped trajectory to ensure that while the surface cracks of the upper glass plate 22 and the lower glass 23 are fully detected, the ultrasonic waves generated by the two ultrasonic detection devices 32 will not collide with each other, avoiding the simultaneous detection of the upper glass plate 22 and the lower glass 23, which will cause the two ultrasonic detection devices 32 to interfere with each other, resulting in inaccurate detection results, thereby ensuring the accuracy of the detection data of the ultrasonic detection equipment 32.

[0049] In the detection structure 3 of the present application, the hydraulic cylinder 1 38 cooperates with the hydraulic transmission component to control the forward and backward movement of the two ultrasonic detection devices 32, and the hydraulic control component cooperates with the compression telescopic rod 3 39 and the hydraulic telescopic rod 2 320 to control the left and right movement of the two ultrasonic detection devices 32, which can ensure the stable and rapid movement of the two ultrasonic detection devices 32, and make the ultrasonic detection devices 32 move at a preset trajectory and speed, avoiding the mutual influence of the two ultrasonic detection devices 32. During the conveying process of the glass door 2 by the feeding structure 1, a comprehensive inspection is completed before the glass door 2 is flipped, thereby reducing damage to the glass door 2 caused by accidents.

[0050] In addition, such as Fig.11 , Fig.12 and Fig.13 As shown, two support springs 2 322 are fixedly connected between the fixing frame 331 and the adjacent fixing vertical plate 310 , and the support springs 2 322 apply tension to the fixing vertical plate 310 to ensure stable resetting of the ultrasonic detection device 32 .

[0051] In addition, in the present application, the ultrasonic detection device 32 uses ultrasonic waves to scan the glass, and determines whether there are cracks on the glass surface through the reflection and refraction of the sound waves. This is a public technology and will not be described in detail here.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
