Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, in particular to a helium leak detection conveying device for an automobile radiator. Background Art

[0002] The car radiator is an important part of the engine cooling system. It is mainly used to dissipate the heat generated during the operation of the engine to the outside world to keep the engine at an appropriate operating temperature. The radiator circulates the coolant to transfer the heat to the metal core of the radiator, and then the air flows through the radiator to take away the heat, thereby achieving cooling. Fig. 9 , Instruction Manual Fig.10 And the instruction manual Fig.11 As shown, 02 in the figure is an automobile radiator in the prior art, wherein a water chamber is provided in the plate-shaped body, heat dissipation fins are evenly distributed on the outer walls on both sides of the plate-shaped body, and a cavity is formed between two adjacent heat dissipation fins on the automobile radiator.

[0003] In order to ensure that there is no gas leakage during the manufacturing and use of the radiator, it is necessary to perform helium leak detection on the basically formed automobile radiator during the production process. The main operation method of helium leak detection is to use the helium leak detection component to inject helium into the sealed radiator. On the one hand, the pressure inside the radiator is detected by the pressure gauge of the helium leak detection component. On the other hand, the helium leak detection instrument of the helium leak detection component is used to detect the surface of the radiator. When the pressure gauge identifies that the pressure inside the radiator becomes smaller or the helium leak detection instrument detects helium leakage on the surface of the radiator, it means that the radiator is not sealed well and there is a leak point.

[0004] When traditional automobile radiators are tested for helium leaks, they are mainly loaded and unloaded manually. Manual loading and unloading is not only time-consuming and labor-intensive, but also requires workers to constantly move and adjust the radiator to ensure that the gas injection interface of the helium leak detection component can be aligned with the orifice on the radiator. It is impossible to quickly locate and align the radiator orifice with the gas injection interface of the helium leak detection component, which is inefficient. Summary of the invention

[0016] Preferably, a plurality of spherical cavities are evenly distributed on the two inner side walls of the U-shaped frame, and a rolling ball is embedded in each spherical cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0018] The present invention integrates linear feeding, suction and dragging loading, linear feeding, feeding self-positioning, linear unloading, flipping and redirection, and hanging transportation to realize automatic transportation of automobile radiator body helium leak detection. Compared with traditional manual loading and unloading, the present invention has a high degree of automation, a fast transportation response speed, and a high degree of connection and matching between various transportation links, which effectively improves the efficiency of automobile radiator body helium leak detection.

[0019] The present invention uses the first cylinder to extend before conveying the automobile radiator body to the inspection station, and then the automobile radiator body is pushed downward by the pusher card strip to continue conveying until the heat dissipating fins at the head of the automobile radiator body are in contact with the positioning plate, at which time the feeding mechanism stops feeding and clamps the automobile radiator body by the positioning plate and the pusher card strip at the rear, thereby positioning the automobile radiator body in the length direction of the platform and cooperating with the baffle plates on both sides to position the automobile radiator body in the width direction of the platform. During feeding, automatic positioning of the automobile radiator body during leak detection can be achieved without frequent manual adjustment, which helps to quickly align the gas injection part on the helium leak detection assembly with the orifice on the automobile radiator body, thereby reducing the time consumption for assembly. In addition, the pusher card strip serves as both a feeding part for pushing the automobile radiator body forward and a positioning part for the automobile radiator body, thereby killing two birds with one stone, without the need for a special additional positioning system, thereby reducing cost investment.

[0020] The present invention pushes the automobile radiator body into the U-shaped frame as the conveyor chain runs. Since the pushing card bar pushes the heat dissipation fins at the very end of the automobile radiator body, the automobile radiator body can be pushed into the U-shaped frame as much as possible. When the second cylinder is extended to hold the upper and lower automobile radiator bodies on the conveyor belt, the rack meshing gear is driven to rotate, and the U-shaped frame is triggered to flip upward, thereby driving the automobile radiator body contained in the U-shaped frame to flip to a vertical state, and adapting to the mounting of the suspension conveying mechanism, effectively ensuring the continuity and orderliness of the conveyor line.

[0021] The present invention drives the rack to move synchronously by telescoping the second cylinder, and converts the horizontal feed into a rotary drive through the meshing transmission effect of the gear and the rack, thereby realizing a linkage effect, so that the flipping of the U-shaped frame and the advance and retreat of the suction cup share the same driving source, and there is no need to set up an additional driving structure for driving the U-shaped frame to rotate, thereby reducing the equipment cost investment, and the degree of coordination between the flipping and the feeding is high, and the overall structural layout is reasonable. In addition, the second worm is used to drive the second worm wheel in one direction, which also has a self-locking effect. When the second cylinder is not working, it helps to maintain the state of the U-shaped frame, thereby ensuring the stability of the automobile radiator body when it is mounted.

[0022] The U-shaped mounting part is specially designed for the appearance of the automobile radiator body, so that the automobile radiator body can be clamped and mounted, and the automobile radiator body can be brought out of the U-shaped mounting part and transported downstream, so as to realize the suspended transportation of the automobile radiator body. In the subsequent transportation process, the space on the ground is not occupied and the vehicle is not restricted by obstacles on the ground. The various regional processes of the automobile radiator body manufacturing can be smoothly connected, so as to effectively improve the transportation efficiency of the automobile radiator body.

[0023] The present invention evenly embeds a plurality of rolling balls on the inner walls on both sides of the U-shaped frame that are in contact with the automobile radiator body. When the automobile radiator body enters the U-shaped frame and moves out of the U-shaped frame, the heat dissipation fins contact the rolling balls so that the rolling balls roll, which can reduce the wear of the heat dissipation fins and avoid excessive damage to the appearance of the heat dissipation fins. When the automobile radiator body enters the U-shaped frame, the relative movement occurs in a direction perpendicular to the heat dissipation fins, and when the automobile radiator body moves out of the U-shaped frame, the relative movement occurs in a direction parallel to the heat dissipation fins. The characteristic that the rolling balls can roll in any direction in the spherical cavity can adapt to the movement of the automobile radiator body in different directions, and the degree of adaptability is high.

The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0041] The conveying device includes a platform 1 and a conveyor belt 3 arranged on one side of the platform 1. The conveyor belt 3 is used to transport the automobile radiator body 02 processed by the upstream production line to the platform 1. The helium leak detection component 01 is arranged above the platform 1 and close to the middle of the platform 1. The helium leak detection component 01 is used to perform helium leak detection on the automobile radiator body 02. By aligning and connecting the gas injection port on the helium leak detection component 01 with the hole on the automobile radiator body 02, helium filling detection can be performed. The helium leak detection component 01 adopts the existing technology, so its specific structure and working principle are not described in detail.

[0042] The platform 1 is provided with a feeding mechanism 2, which is used to feed and transport the automobile radiator body 02 downstream, and when passing under the helium leak detection component 01, the automobile radiator body 02 can be positioned so that the helium leak detection component 01 can be assembled and tested. The side of the platform 1 opposite to the conveyor belt 3 is provided with a feeding mechanism 4 for feeding the automobile radiator body 02 on the conveyor belt 3 to the feeding mechanism 2. The feeding mechanism 2 includes a pair of conveyor chains 21 that can be synchronously circulated and a plurality of respectively Pushing bars 22 are evenly distributed on the two conveying chains 21, and a suspension 201 is provided above the platform 1. A first cylinder 202 is vertically fixed on the suspension 201, and a positioning plate 203 is fixed to the end of the telescopic rod of the first cylinder 202. The pushing bars 22 are in contact with the corresponding heat dissipation fins on the helium leak detection component 01, and the positioning plate 203 is in contact with the corresponding heat dissipation fins to achieve positioning of the automobile radiator body 02 during leak detection, that is, during the feeding process, leak detection positioning can be automatically achieved.

[0043] See also Figure 1 and Figure 2 A flipping mechanism 5 is provided on the downstream side of the platform 1, a linkage mechanism 6 is provided on the side of the platform 1, and a hanging conveying mechanism 7 is arranged above the flipping mechanism 5. The linkage mechanism 6 is used to trigger the flipping mechanism 5 to work when the feeding mechanism 4 feeds. The flipping mechanism 5 is used to flip the tested automobile radiator body 02 to a vertical state for hanging conveying by the hanging conveying mechanism 7.

[0044] The automobile radiator body 02 processed in the previous process is conveyed to the stand 1 by the conveyor belt 3, and the automobile radiator body 02 on the conveyor belt 3 is loaded to the feeding mechanism 2 by the loading mechanism 4. The automobile radiator body 02 can be conveyed to the bottom of the helium leak detection component 01 by the conveyor belt 3, and can be positioned by the positioning plate 203 to facilitate leak detection. After the leak detection is completed, the automobile radiator body 02 is continuously conveyed downstream to the flipping mechanism 5 by the feeding mechanism 2. When the loading mechanism 4 continues to work to load the automobile radiator body 02 at the next position onto the feeding mechanism 2, the flipping mechanism 5 can be triggered to work in a linked manner, and the horizontal automobile radiator body 02 is flipped and adjusted to a vertical state, so as to facilitate the hanging conveying mechanism 7 to mount the automobile radiator body 02 for hanging conveyance. It can be seen that the present invention integrates linear feeding, suction and dragging loading, linear feeding, feeding self-positioning, linear unloading, flipping and turning, and hanging transportation to realize the automatic transportation of automobile radiator body 02 helium leak detection. Compared with traditional manual loading and unloading, it has a high degree of automation, fast transportation response speed, and high connection and matching degree of each transportation link, which effectively improves the efficiency of automobile radiator body 02 helium leak detection.

[0045] See also Figure 5 and Figure 6 The feeding mechanism 2 also includes a bearing seat 23, a first shaft rod 24, a sprocket 25 and a driving assembly 26. The first shaft rods 24 are rotatably installed on both sides of the frame 1 in the length direction through the bearing seats 23. Both ends of the two first shaft rods 24 are fixedly mounted with sprockets 25. The two conveying chains 21 are respectively driven and mounted on the corresponding sprockets 25 on the same side. The driving assembly 26 is arranged on the frame 1 to provide drive for the synchronous operation of the two conveying chains 21. Through the operation of the driving assembly 26, one of the first shaft rods 24 is driven to rotate, and then the sprockets 25 at both ends of the first shaft rod 24 are driven to rotate. Under the action of the first shaft rod 24 and the sprocket 25 on the other side, the two conveying chains 21 can be driven to run, thereby achieving the feeding effect.

[0046] Side baffles 101 are fixed to the edges of the two long sides above the platform 1, and a feed port 102 for the automobile radiator body 02 to pass through is provided on one side baffle 101 at a position corresponding to the position of the conveyor belt 3, and a clearance notch 103 is provided on the other side baffle 101 at a position corresponding to the position of the feeding mechanism 4. The helium leak detection assembly 01 is arranged on the baffles 101 on both sides, and the suspension 201 is installed on the baffles 101 on both sides. The position of the conveyor belt 3 corresponds to the position of the feed port 102, and the feeding mechanism 4 drags the automobile radiator body 02 on the conveyor belt 3 from the feed port 102 to the feeding mechanism 2.

[0047] Specifically, first, the driving assembly 26 drives the two conveying chains 21 to run synchronously until the corresponding two pushing material card strips 22 move to the position corresponding to the heat dissipation fin position farthest from the flip mechanism 5 on the automobile radiator body 02, and then the automobile radiator body 02 on the conveyor belt 3 is dragged along the length direction of the pushing material card strip 22 to the two pushing material card strips 22 through the feeding mechanism 4. Fig. 9 As shown, the two material pushing bars 22 will be tightly attached to the side of the last heat dissipating fin on the automobile radiator body 02 away from the flip mechanism 5, and the running conveying chain 21 will drive the material pushing bars 22 to move, and the material pushing bars 22 can push the automobile radiator body 02 to move downward to feed materials.

[0048] The driving assembly 26 includes a mounting base 261, a driving motor 262, a bracket 263 and a first worm 264. The driving motor 262 is fixed on the platform 1 and close to the first shaft 24 on one side through the mounting base 261. The first worm 264 is rotatably mounted above the platform 1 through a pair of brackets 263. The output shaft of the driving motor 262 is fixedly connected to one end of the first worm 264. The first shaft 24 is fixedly sleeved with a first worm gear 265, which meshes with the first worm gear 264. The driving motor 262 works, and its output shaft drives the first worm 264 to rotate. The rotating first worm 264 meshes with the first worm gear 265 and drives the first shaft 24 on the corresponding side to rotate, thereby providing drive for the operation of the two conveying chains 21.

[0049] In addition, the transmission method of utilizing the first worm 264 to mesh and drive the first worm 264 has a one-way transmission effect, and thus when the conveying chain 21 is not in operation, it can achieve a self-locking effect, thereby preventing the conveying chain 21 from deflecting arbitrarily and causing the automobile radiator body 02 to shift, and the conveying accuracy is high.

[0050] In addition, if Fig. 9 As shown, before the automobile radiator body 02 is transported to the inspection station by the feeding mechanism 2, the first cylinder 202 is extended to push the positioning plate 203 downward, and then the automobile radiator body 02 is pushed by the pushing card strip 22 to continue to be transported until the heat dissipating fins at the head of the automobile radiator body 02 fit and contact with the positioning plate 203. The feeding mechanism 2 stops feeding, and the positioning plate 203 and the rear pushing card strip 22 cooperate to clamp the automobile radiator body 02 to achieve the positioning of the automobile radiator body 02 in the length direction of the stand 1. In addition, when the feeding mechanism 2 transports the automobile radiator body 02, the side baffles 101 on both sides slide and fit with the two sides of the automobile radiator body 02 respectively, play a blocking role, and achieve the positioning of the automobile radiator body 02 in the width direction of the stand 1.

[0051] See also Figure 1-Figure 4The feeding mechanism 4 includes a mounting plate 41, a second cylinder 42, a mounting frame 43 and a suction cup 44. The mounting plate 41 is fixed to the side of the platform 1, and the second cylinder 42 is fixed to the mounting plate 41. The mounting frame 43 is fixed to the end of the telescopic rod of the mounting plate 41. The second cylinder 42 and the mounting frame 43 both correspond to the position of the clearance gap 103. When the second cylinder 42 is telescopic, its telescopic rod, the mounting frame 43 and the suction cup 44 can all pass through the clearance gap 103. The clearance gap 103 is used to make space for the movement of the mounting frame 43 and the suction cup 44 to avoid obstruction and interference. A pair of suction cups 44 for holding the automobile radiator body 02 is provided on the mounting frame 43. When the second cylinder 42 retreats to the limit position, the mounting frame 43 and the suction cup 44 are reset to the outer side of the side baffle 101.

[0052] The second cylinder 42 extends to push the mounting frame 43 and the suction cup 44 toward the side of the conveyor belt 3 until the suction cup 44 sucks the side of the automobile radiator body 02 on the conveyor belt 3. Then the second cylinder 42 retracts to suck and drag the automobile radiator body 02 on the conveyor belt 3 from the feed port 102 to the feeding mechanism 2, thereby achieving the feeding effect.

[0053] In addition, if Figure 3 and Figure 5 As shown, the feed port 102 has an arc-shaped guide portion 1021 on one side close to the helium leak detection component 01. After the automobile radiator body 02 is loaded into place, the pushing effect of the pushing card bar 22 when the conveying chain 21 is running can push the automobile radiator body 02 downstream. Combined with the guiding effect of the arc-shaped movement of the arc-shaped guide portion 1021, the automobile radiator body 02 can be smoothly guided between the side baffles 101 on both sides, so that the baffles 101 on both sides can limit and block the automobile radiator body 02 in the width direction of the platform 1.

[0054] As the instruction manual Figure 1-Figure 4 As shown, the flip mechanism 5 includes a vertical frame 51, a second shaft rod 52 and a U-shaped frame 53. The two vertical frames 51 are vertically arranged on the downstream side of the platform 1, the second shaft rod 52 is rotatably mounted on the two vertical frames 51, and the U-shaped frame 53 is fixedly mounted on the second shaft rod 52.

[0055] The linkage mechanism 6 includes an L-shaped frame 61, a third shaft 62, a connecting frame 63, a rack 64, a gear 65 and a second worm 66. The third shaft 62 is rotatably mounted on the side of a side baffle 101 through a plurality of L-shaped frames 61. The rack 64 is fixedly mounted on the top of the mounting frame 43 through the connecting frame 63. The gear 65 is fixed on one end of the third shaft 62 and meshes with the rack 64 accordingly. The second worm 66 is fixed on the other end of the third shaft 62. A second worm wheel 67 is fixed on one end of the second shaft 52, and the second worm wheel 67 meshes with the second worm 66 accordingly.

[0056] When the second cylinder 42 telescopes and drives the mounting frame 43 to perform translational adjustment, the rack 64 can be driven to move synchronously under the fixed connection of the connecting frame 63. The moving rack 64 can engage the driving gear 65 and drive the third shaft 62 and the second worm 66 to rotate. The second worm 66 engages and drives the second worm wheel 67 and drives the second shaft 52 and the U-shaped frame 53 to rotate, providing drive for the flipping of the automobile radiator body 02.

[0057] like Fig.10 As shown, before the automobile radiator body 02 is fully inserted, the U-shaped frame 53 is in a horizontal state, and the height of its inner cavity corresponds to the height above the conveying chain 21. As the conveying chain 21 runs, the pushing card bar 22 pushes the automobile radiator body 02 into the U-shaped frame 53. Since the pushing card bar 22 pushes the cooling fins at the very end of the automobile radiator body 02, the automobile radiator body 02 can be pushed into the U-shaped frame 53 as much as possible. When the second cylinder 42 is extended to hold the upper and lower automobile radiator bodies 02 of the conveyor belt 3, the rack 64 is driven to engage the gear 65 to rotate, and the U-shaped frame 53 is triggered to flip upward, thereby driving the automobile radiator body 02 contained in the U-shaped frame 53 to flip to a vertical state, and adapting to the mounting of the suspension conveying mechanism 7, effectively ensuring the continuity and orderliness of the conveying line.

[0058] In addition, the rack 64 is driven to move synchronously through the extension and retraction of the second cylinder 42, and the horizontal feed is converted into a rotational drive through the meshing transmission effect of the gear 65 and the rack 64, thereby realizing a linkage effect. The flipping of the U-shaped frame 53 and the advance and retreat of the suction cup 44 share the same driving source, and there is no need to set up an additional driving structure for driving the U-shaped frame 53 to rotate, thereby reducing the equipment cost investment, and the degree of coordination between the flipping and the feeding is high, and the overall structural layout is reasonable. In addition, the second worm 66 is used to drive the second worm wheel 67 in one direction, which also has a self-locking effect. When the second cylinder 42 is not working in an extension and retraction mode, it helps to maintain the state of the U-shaped frame 53 and ensure the stability of the automobile radiator body 02 when it is mounted.

[0059] Among them, Figure 4 and Fig.10As shown, a plurality of spherical cavities 531 are evenly distributed on the two inner side walls of the U-shaped frame 53, and a rolling ball 532 is embedded in each spherical cavity 531. A plurality of rolling balls 532 are evenly embedded on the inner walls on both sides of the U-shaped frame 53 that are in contact with the automobile radiator body 02. When the automobile radiator body 02 enters the U-shaped frame 53 and moves out of the U-shaped frame 53, the heat dissipation fins contact the rolling balls 532 so that the rolling balls 532 roll, which can reduce the wear on the heat dissipation fins and avoid excessive damage to the appearance of the heat dissipation fins. When the automobile radiator body 02 enters the U-shaped frame 53, the relative movement occurs in a direction perpendicular to the heat dissipation fins. When the automobile radiator body 02 moves out of the U-shaped frame 53, the relative movement occurs in a direction parallel to the heat dissipation fins. The characteristic that the rolling balls 532 can roll in any direction in the spherical cavity 531 can adapt to the movement of the automobile radiator body 02 in different directions, and has a high degree of adaptability.

[0060] As the instruction manual Figure 1 and attached Figure 8 As shown, the hanging conveying mechanism 7 includes a conveying track 71 arranged in the air, a plurality of movable seats 72 arranged on the conveying track 71, a plurality of connecting arms 73 respectively vertically fixed at the bottom of the movable seats 72, and U-shaped mounting parts 74 respectively fixed at the bottom ends of the connecting arms 73. The U-shaped mounting parts 74 can be matched and clamped on the automobile radiator body 02, and cooperate with the heat dissipation fin clamping and mounting on the automobile radiator body 02. The movable seat 72 can move along the conveying track 71. When the U-shaped frame 53 flips the automobile radiator body 02 to a vertical state, as shown in FIG. Fig.11 As shown, the corresponding movable seat 72 moves along the conveying track 71, and under the action of the connecting arm 73, drives the U-shaped mounting member 74 to be inserted from the side of the automobile radiator body 02 to between the two top heat dissipation fins. Through the special design of the U-shaped mounting member 74 for the appearance of the automobile radiator body 02, the automobile radiator body 02 can be clamped and mounted, and the automobile radiator body 02 can be brought out of the U-shaped frame 53 and conveyed downstream, thereby realizing the suspended conveyance of the automobile radiator body 02. In the subsequent conveying process, it does not occupy the space on the ground and is not restricted by ground obstacles. It can smoothly connect the various regional processes of the automobile radiator body 02 manufacturing, effectively improving the conveying efficiency of the automobile radiator body 02.

[0061] In addition, it is worth mentioning that an indicator light 701 is installed on each movable seat 72. When the detected automobile radiator body 02 is a defective product, the indicator light 701 on the corresponding movable seat 72 lights up red. When the detected automobile radiator body 02 is a qualified product, the indicator light 701 on the corresponding movable seat 72 lights up green. The specific structure, lighting control method and circuit of the indicator light 701 and the specific lighting principle all adopt the existing technology and will not be described in detail in this application. In the subsequent process, the staff can eliminate and select defective products according to the lighting situation for processing, so as to avoid the defective products from flowing into the subsequent processing process, which is conducive to the effective control of the overall quality of the automobile radiator body 02.

[0062] 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.
