Description

Technical Field

[0001] This invention relates to the field of refrigerator manufacturing technology, specifically to a refrigerator drawer production conveying and testing device. Background Technology

[0002] Refrigerators have the basic function of refrigerating food, providing space for refrigeration or freezing. Existing refrigerators are generally divided into multiple compartments, with each compartment using drawers to store food.

[0003] During the production process, refrigerator drawers must be inspected to remove defective products and ensure product quality. In current technology, the quality of refrigerator drawers is generally inspected manually by visual inspection. However, manual inspection is inefficient, and long hours of repetitive work may cause eye fatigue among workers, leading to decreased inspection efficiency and the possibility of incorrect inspections, which in turn affects the yield rate of the drawers. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator drawer production conveying and testing device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a refrigerator drawer production conveying and testing device, comprising a testing platform, with support legs fixedly installed at each of the four corners of the testing platform, and a top plate fixedly installed on the top of the four support legs. The testing platform is located at the bottom of the top plate, and a second testing device is fixedly installed at the bottom of the top plate. Two pairs of support columns are symmetrically arranged on both sides of the testing platform, and each pair of support columns is fixedly connected to its two adjacent support legs. A gantry frame is fixedly installed on the top of one of the support columns, and a first testing device is fixedly installed at the top center of the gantry frame.

A rotating shaft is rotatably installed inside each of the opposite ends of the two sets of protective shells. One end of each rotating shaft is fixedly connected to the output end of the motor. A pulley is fixedly installed at each end of each rotating shaft. Two pulleys are symmetrically rotatably installed at the opposite ends of the two sets of protective shells. A conveyor belt is driven by both pulleys on the same side. The two conveyor belts located at the bottom of the first detection device are the feeding belts, and the two conveyor belts on the side away from the first detection device are the unloading belts. The device also includes:

[0007] A mounting base is fixedly installed in the middle of the upper surface of the detection platform. Two notches are symmetrically opened on the two side walls of the mounting base, and an arc-shaped groove is opened at the bottom of the notch.

[0008] The flipping auxiliary component includes two transmission gears and a rotating seat. The two transmission gears are respectively disposed inside an arc-shaped groove, and an extension plate is fixedly connected to the side wall of each transmission gear.

[0009] The rotating seat is located at the end of the extension plate near the side of the feeding belt;

[0010] A pneumatic suction cup is rotatably mounted on the end of the extension plate away from the rotating seat and away from the transmission gear.

[0011] Furthermore, a set of mounting holes are provided on both sides of the arc-shaped groove, and a cylindrical hole is provided in the middle of the mounting base. The arc-shaped groove communicates with the cylindrical hole, and a slide rod is slidably installed inside the cylindrical hole. Several toothed grooves are evenly provided on the side wall of the slide rod. A hydraulic telescopic rod is provided at the bottom of the mounting base. The hydraulic telescopic rod is fixedly installed at the bottom of the detection platform, and the output end of the hydraulic telescopic rod passes through the detection platform and is fixedly connected to the bottom of the slide rod.

[0012] Furthermore, each of the transmission gears is fixedly connected to a connecting shaft at its central shaft. The connecting shafts are rotatably installed inside a corresponding set of mounting holes. Both transmission gears are meshed with several tooth grooves. A connecting cylinder is fixedly connected to the end of the extension plate closest to the feeding belt away from the transmission gear. A transmission thread is provided on the inner wall of the connecting cylinder. An electric telescopic rod is fixedly installed at the bottom of the extension plate closest to the feeding belt away from the transmission gear. A connecting seat is rotatably installed on the output end of the electric telescopic rod.

[0013] Furthermore, the interior of the rotating seat has an upward-opening square groove, and two rotating rods are symmetrically and rotatably installed at both ends of the square groove. A pair of connecting rods are symmetrically and fixedly connected to both ends of the rotating rods through the side wall of the rotating seat, and a cylindrical clamping seat is fixedly installed at the end of the pair of connecting rods away from the rotating rods.

[0014] Furthermore, a small gear is fixedly installed in the middle of each rotating rod, and a connecting sleeve is fixedly connected to the middle of the lower surface of the rotating seat. The rotating seat is rotatably mounted on the connecting cylinder through the connecting sleeve. A circular hole is opened in the middle of the lower surface of the rotating seat. A horizontal plate is set inside the rotating seat. The horizontal plate is located at the bottom of the two small gears. A rack is fixedly connected to both ends of the horizontal plate. The two small gears are located between the two racks. The racks are respectively meshed with the small gear closest to them. The two racks are slidably set between the inner walls of the two sides of the square groove. A square hole is opened in the middle of the upper surface of the horizontal plate. A square rod is slidably set inside the square hole. A pressure plate is fixedly connected to the top of the square rod. A spring is set between the bottom of the square rod and the bottom inner wall of the square hole.

[0015] Furthermore, a cylindrical seat is fixedly connected to the center of the lower surface of the cross plate. The cylindrical seat is slidably disposed inside the circular hole. An annular groove is formed in the middle of the cylindrical seat, and several grooves are evenly formed on the side wall of the annular groove.

[0016] Furthermore, a threaded cylinder is rotatably mounted on the annular groove. The threaded cylinder is located inside the connecting cylinder and is threadedly connected to the transmission thread. The bottom of the threaded cylinder is fixedly mounted on the connecting seat. A cylindrical friction element is installed inside each groove.

[0017] The present invention has the following beneficial effects:

[0018] (1) In the process of transporting refrigerator drawers by conveyor belt, the present invention works in conjunction with the hydraulic telescopic rod at the bottom of the base and the flipping auxiliary component. After the bottom of the refrigerator drawer is detected by the first detection device, the flipping auxiliary component can drive the refrigerator drawer to rotate, thereby facilitating the detection of each side wall of the refrigerator drawer. This solves the problem of low efficiency and false detection caused by manual detection.

[0019] (2) Both the connecting rod and the cylindrical clamping seat of the present invention are elastic. On the one hand, it can prevent the rotating rod from rotating excessively and breaking or deforming the refrigerator drawer. On the other hand, depending on the size of the refrigerator drawer, the elasticity of the connecting rod can be used to deform the drawer, so that the two cylindrical clamping seats can support the refrigerator drawer, thus increasing the applicability of the device.

[0020] (3) The present invention uses an electric telescopic rod. When the electric telescopic rod is retracted, it can pull the horizontal plate to slide. In conjunction with the meshing of the pinion and rack, it can drive the rotating rods on both sides to rotate, causing the cylindrical pressing seat to lift up and support the refrigerator drawer to fix it.

[0021] The extension of the electric telescopic rod can drive the horizontal plate and the rotating base to rotate as a whole, thereby flipping the refrigerator drawer. This makes it easier for the second detection device to detect each side wall of the refrigerator drawer, increasing the practicality of the device.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figures 1-4As shown, this invention is a refrigerator drawer production conveying and testing device, including a testing platform 1. Support legs 11 are fixedly installed at each of the four corners of the testing platform 1. A top plate 12 is fixedly installed on the top of the four support legs 11. The testing platform 1 is located at the bottom of the top plate 12. A second testing device 121 is fixedly installed at the bottom of the top plate 12. Two pairs of support columns 13 are symmetrically arranged on both sides of the testing platform 1. Each pair of support columns 13 is fixedly connected to its two adjacent support legs 11. A gantry frame 131 is fixedly installed on the top of one of the support columns 13. A first testing device 14 is fixedly installed at the top center of the gantry frame 131. A set of conveyor belts is fixedly installed between each pair of support columns 13 and its two adjacent support legs 11. The protective shell 15 has a motor 151 fixedly installed on the side wall of each of the two sets of conveyor belt protective shells 15 at their opposite ends. A rotating shaft 16 is rotatably installed inside each of the opposite ends of the two sets of conveyor belt protective shells 15. One end of the rotating shaft 16 is fixedly connected to the output end of the motor 151. A pulley 161 is fixedly installed at each end of the rotating shaft 16. Two pulleys 162 are symmetrically rotatably installed at the opposite ends of the two sets of conveyor belt protective shells 15. A conveyor belt 17 is jointly driven and installed on both pulley 161 and pulley 162 on the same side. The two conveyor belts 17 located at the bottom of the first detection device 14 are feeding belts, and the two conveyor belts 17 on the side away from the first detection device 14 are discharging belts. The device also includes:

[0036] A mounting base 2 is fixedly installed in the middle of the upper surface of the testing platform 1. Two notches 21 are symmetrically opened on the two side walls of the mounting base 2, and an arc groove 211 is opened at the bottom of the notch 21.

[0037] The flipping auxiliary component includes two transmission gears 3 and a rotating seat 4. The two transmission gears 3 are respectively disposed inside an arc-shaped groove 211, and extension plates 31 are fixedly connected to the side walls of the transmission gears 3.

[0038] The rotating seat 4 is located at the end of the extension plate 31 near the side of the feeding belt;

[0039] A pneumatic suction cup 32 is rotatably mounted on the end of the extension plate 31 away from the rotating seat 4 and away from the transmission gear 3.

[0040] A set of mounting holes 212 are provided on both sides of the arc-shaped groove 211. A cylindrical hole 22 is provided in the middle of the mounting base 2. The arc-shaped groove 211 is connected to the cylindrical hole 22. A slide rod 23 is slidably installed inside the cylindrical hole 22. Several toothed grooves 231 are evenly provided on the side wall of the slide rod 23. A hydraulic telescopic rod 24 is provided at the bottom of the mounting base 2. The hydraulic telescopic rod 24 is fixedly installed at the bottom of the detection platform 1. The output end of the hydraulic telescopic rod 24 passes through the detection platform 1 and is fixedly connected to the bottom of the slide rod 23.

[0041] The hydraulic telescopic rod moves the slide bar 23 downwards, which meshes with the transmission gear 3 and the tooth groove 231, driving the two transmission gears 3 to rotate until the extension plate 31 is in a vertical state. This facilitates the movement of the flipping auxiliary component with the refrigerator drawer fixed to it to the bottom of the second detection device 121 for easy detection, and also facilitates the transport of the refrigerator drawer between the flipping auxiliary component and the pneumatic suction cup 32.

[0042] Example 2

[0043] Please see Figure 5 As shown, a connecting shaft 301 is fixedly connected to the central shaft of each transmission gear 3. The connecting shaft 301 is rotatably installed inside a corresponding set of mounting holes 212. Both transmission gears 3 are meshed with several tooth grooves 231. A connecting cylinder 33 is fixedly connected to the end of the extension plate 31 near the feeding belt away from the transmission gear 3. A transmission thread 331 is provided on the inner wall of the connecting cylinder 33. An electric telescopic rod 34 is fixedly installed at the bottom of the extension plate 31 near the feeding belt away from the transmission gear 3. A connecting seat 341 is rotatably installed on the output end of the electric telescopic rod 34.

[0044] The interior of the rotating seat 4 has an upward-facing square groove 401. Two rotating rods 41 are symmetrically and rotatably mounted at both ends of the square groove 401. A pair of connecting rods 411 are symmetrically and fixedly connected through the side wall of the rotating seat 4 at both ends of the rotating rods 41. A cylindrical pressing seat 412 is fixedly installed at the end of the pair of connecting rods 411 away from the rotating rods 41.

[0045] When the electric telescopic rod 34 retracts, it pulls the horizontal plate 45 to move. Since the pinion 42 is meshed with the rack 451, it can drive the rotating rods 41 on both sides to rotate. The cylindrical clamping seats 412 installed on the connecting rod 411 are raised until the two cylindrical clamping seats 412 are tightly pressed against the two inner walls of the refrigerator drawer, which makes it easier to tighten and fix the refrigerator drawer, and increase the stability of the refrigerator during transportation.

[0046] Example 3

[0047] Please see Figures 6-7As shown, a small gear 42 is fixedly installed in the middle of the rotating rod 41. A connecting sleeve 43 is fixedly connected to the middle of the lower surface of the rotating seat 4. The rotating seat 4 is rotatably mounted on the connecting cylinder 33 through the connecting sleeve 43. A circular hole 44 is opened in the middle of the lower surface of the rotating seat 4. A horizontal plate 45 is set inside the rotating seat 4. The horizontal plate 45 is located at the bottom of the two small gears 42. A rack 451 is fixedly connected to both ends of the horizontal plate 45. The two small gears 42 are located between the two racks 451. The racks 451 are respectively meshed with the small gear 42 closest to them. The two racks 451 are slidably set between the inner walls of the two sides of the square groove 401. A square hole 452 is opened in the middle of the upper surface of the horizontal plate 45. A square rod 453 is slidably set inside the square hole 452. A pressure plate 454 is fixedly connected to the top of the square rod 453. A spring 455 is set between the bottom of the square rod 453 and the bottom inner wall of the square hole 452.

[0048] When the electric telescopic rod 34 extends, the horizontal plate 45 moves toward the opening of the square slot 401, and the pressure plate 454 moves synchronously. It will first contact the inner wall of the refrigerator drawer, and then the spring 455 is compressed. This makes it easier to press the refrigerator drawer onto the pneumatic suction cup 32 before the cylindrical pressing seat 412 moves in the opposite direction and separates from the inner wall of the refrigerator drawer, so that the pneumatic suction cup 32 can fix the refrigerator drawer.

[0049] A cylindrical seat 46 is fixedly connected to the center of the lower surface of the horizontal plate 45. The cylindrical seat 46 is slidably disposed inside the circular hole 44. An annular groove 461 is provided in the middle of the cylindrical seat 46. Several grooves 462 are evenly provided on the side wall of the annular groove 461.

[0050] A threaded cylinder 47 is rotatably mounted on the annular groove 461. The threaded cylinder 47 is located inside the connecting cylinder 33 and is threadedly connected to the transmission thread 331. The bottom of the threaded cylinder 47 is fixedly mounted on the connecting seat 341. A cylindrical friction element 48 is installed inside each groove 462.

[0051] In use, place the refrigerator drawer to be tested with its opening facing down on the two conveyor belts 17 located at the bottom of the gantry frame 131, i.e., a pair of feeding belts. The motor 151 drives the rotating shaft 16 and the pulley 161 to rotate, and the conveyor belts 17 rotate synchronously, which can drive the refrigerator drawer to move and transport it. In addition, by controlling the motor 151 to work intermittently, the conveyor belts 17 can be driven to rotate intermittently to transport the refrigerator drawer.

[0052] When the refrigerator drawer is transported to the bottom of the first detection device 14 via the conveyor belt 17, the first detection device 14 can detect the bottom detection surface of the refrigerator drawer, and then it is transported to the end of the feeding belt via the conveyor belt 17, where the conveyor belt 17 stops moving.

[0053] Then the electric telescopic rod 34 retracts, pulling the threaded cylinder 47 down. Since the threaded cylinder 47 is installed inside the annular groove 461, the horizontal plate 45 and the cylindrical seat 46 move synchronously. The rack 451 moves towards the bottom of the square groove 401. Since the pinion 42 meshes with the rack 451, it can drive the rotating rods 41 on both sides to rotate. The cylindrical pressing seat 412 installed on the connecting rod 411 tilts up until the two cylindrical pressing seats 412 are tightly pressed against the two inner walls of the refrigerator drawer, thus tightening and fixing the refrigerator drawer.

[0054] In addition, both the connecting rod 411 and the cylindrical pressing seat 412 are elastic. On the one hand, this can prevent the rotating rod 41 from rotating excessively and breaking or deforming the refrigerator drawer. On the other hand, depending on the size of the refrigerator drawer, the elasticity of the connecting rod 411 can be used to deform it, so that the two cylindrical pressing seats 412 can support the refrigerator drawer, thus increasing the applicability of the device.

[0055] Then the hydraulic telescopic rod 24 works, driving the slide rod 23 to move down. Through the meshing of the transmission gear 3 and the tooth groove 231, it can drive the two transmission gears 3 to rotate. The transmission gear 3 on the side closer to the feeding belt rotates clockwise, and the transmission gear 3 on the side closer to the unloading belt rotates counterclockwise. The rotating seat 4 at the end of the extension plate 31 is lifted until the extension plate 31 is in a vertical state.

[0056] At this time, the pneumatic suction cup 32 works, adsorbing the refrigerator drawer onto the suction cup of the pneumatic suction cup 32, and the second detection device 121 can detect the side wall of the refrigerator drawer.

[0057] Then, the electric telescopic rod 34 extends, the horizontal plate 45 moves toward the opening of the square slot 401, the pressure plate 454 moves synchronously and presses tightly against the inner wall of the refrigerator drawer, the spring 455 is compressed, and at the same time the cylindrical pressing seat 412 moves in the opposite direction and disengages from the inner wall of the refrigerator drawer.

[0058] During this process, the threaded cylinder 47 and the cylindrical friction element 48 are threaded together inside the connecting cylinder 33. When the electric telescopic rod 34 retracts and pulls the horizontal plate 45 downward, the threaded cylinder 47 rotates clockwise. Because the cylindrical friction element 48 is pushed into the deepest part of the groove 462, the cylindrical friction element 48 does not contact the inner wall of the threaded cylinder 47, allowing the threaded cylinder 47 to rotate smoothly while the horizontal plate 45 does not rotate. However, when the electric telescopic rod 34 extends and pushes the horizontal plate upward, the threaded cylinder 47 rotates counterclockwise. As the friction cylinder friction element 48 is pushed into the shallowest part of the groove 462 and pressed tightly against the inner wall of the threaded cylinder 47, it is locked in place. At this time, the rotation of the threaded cylinder 47 inside the connecting cylinder 33 can drive the horizontal plate 45 and the rotating seat 4 to rotate as a whole. The refrigerator drawer clamped between the pressure plate 454 and the pneumatic suction cup 32 can rotate synchronously, thereby realizing the flipping of the refrigerator drawer. This makes it easier for the second detection device 121 to detect each side wall of the refrigerator drawer, solving the problem of low efficiency and false detection caused by manual detection.

[0059] After the test is completed, the hydraulic telescopic rod 24 extends, driving the two transmission gears 3 to rotate in opposite directions, which can reset the flipping auxiliary component. When the pneumatic suction cup 32 is reset, the refrigerator drawer can be placed smoothly on the feeding belt, and the suction cup can be released to smoothly feed the material.
