Description

Technical Field

[0001] The present invention relates to the technical field of leak testing devices, and particularly to a dual-station leak detection flexible workstation. Background Art

[0002] An automobile engine mainly consists of four major assemblies: a cylinder head cover, a cylinder head, a cylinder block, and an oil pan. Among them, the cylinder head cover of the engine, as a part of sealing the top of the engine, is hermetically connected to the outside of the cylinder head and cylinder block of the engine, playing a role in ensuring the overall sealing of the engine and protecting the cylinder head system from external interference. The importance of the sealing performance of the cylinder head cover requires leak testing to be carried out before the cylinder head cover leaves the factory to ensure its qualification.

[0003] Some existing leak testing devices, as disclosed in publication number CN 117007251A, generally can only test one product to be inspected at a time, which makes the detection efficiency very limited. Conventional leak testing devices can basically only achieve the single function of leak testing. Usually, after the cover is detected, various openings or holes for leak testing on its cover body need to be sealed by covering the cover body. This is usually manually covered or transferred to another covering mechanism for automatic covering after leak testing. However, due to the existence of the transfer process, it will inevitably reduce the overall processing efficiency, and it is also easy for impurities in the external environment to enter the product during the transmission process, which is not conducive to maintaining the cleanliness inside the product. Therefore, it is necessary to further optimize leak testing to improve the efficiency of leak testing and the effective integration with different processes of the overall production line.

Also, in the description of the solution, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0019] As Figures 1 to 6 shown, the present invention discloses a dual-station leak detection flexible workstation, which includes a workbench 1 and two detection stations arranged on the workbench 1. Each detection station is provided with a positioning cylinder 2, a plugging head 3, a positioning stage 4 and a leak detection stage 5. A group of positioning cylinders 2 are suspended above the positioning stage 4 at intervals along the edge of the positioning stage 4 in a liftable manner, and can limit the product to be tested 7 on the positioning stage 4 by pressing down. A group of limit posts are arranged on the positioning stage 4, and the inner contour formed by the group of limit posts is adapted to the outer contour of the product to be tested 7 to limit the position of the product to be tested 7; the plugging head 3 is also suspended above the positioning stage 4 in a liftable manner, and can plug the top opening of the product to be tested 7 by pressing down; a driving track 6 is arranged on the workbench 1, two positioning stages 4 are mounted above the driving track 6, two leak detection stages 5 are slidably arranged on the driving track 6, and the two leak detection stages 5 are connected into one body through a first connecting rod 501 and are driven by a driving mechanism to move synchronously along the driving track 6. A detection plate 502 is arranged on the leak detection stage 5 in a liftable manner to be hermetically docked with the detection port 701 at the bottom of the product to be tested 7. A leak detector 8 is arranged at the bottom of the workbench 1, and detection air paths are arranged in the two detection plates 502 to connect the leak detector 8 and the product to be tested 7 for leak detection.

[0020] This solution uses a driving track 6 and a dual-channel leak detector 8 to cooperate with the dual-detection stations, enabling two leak tests to be carried out synchronously at one time, improving the processing efficiency of one operation and reducing equipment costs. Among them, a diaphragm cylinder 503 is provided on the leak detection table 5 to drive the detection plate 502 to move upward. Guide rods 504 are respectively inserted between the two sides of the leak detection table 5 and the detection plate 503. The bottom of the guide rod 504 has a chassis with a diameter larger than its rod part, and a return spring 505 is sleeved on the guide rod 504. One end of the return spring 505 abuts against the chassis, and the other end abuts against the bottom of the leak detection table 5 to drive the detection plate 502 to move downward and reset. The diaphragm cylinder 503 and the return spring 505 cooperate together to realize the up and down movement of the detection plate 502.

[0021] Furthermore, the side part of the leak detection table 5 is connected to the third connection block 11 through the second connecting rod 12 to form an integrated unit, and the two move synchronously. The bottom of the third connection block 11 is slidably arranged on the driving track 6 through a slider. The second connecting rod 12 and the third connection block 11 form an extended connection mechanism that moves synchronously with the leak detection table 5, enabling other processing mechanisms related to the product to be tested to be arranged on the third connection block 11, so that after the leak test is completed, the processing mechanism can be switched through the movement of the leak detection table 5 for processing, forming a continuous operation, improving production efficiency and production rhythm, reducing unnecessary equipment structures, and saving production costs.

[0022] Specifically, in the preferred embodiment, the product to be tested 7 is preferably an engine hood, and its bottom has a detection port 701. A sealing ring is fixedly arranged on the edge of the detection port 701 to seal its butt joint with the detection plate 503, so as to ensure that after the detection plate 503 abuts against the detection port 701, the sealing ring is squeezed to achieve a sealing effect.

[0023] A cover body 702 needs to be added to the detection port 701 after the leak test is completed, and there is a through hole 703 on one side of the detection port 701. Since the inner diameter of the through hole 703 is relatively narrow, it is necessary to detect whether the through hole 703 is conducting before adding the cover body 702. Therefore, in the preferred embodiment, a cover body installation mechanism for adding the cover body 702 to the detection port 701 is slidably arranged on the driving track 6, and a through hole detection mechanism for detecting the conducting state of the through hole 703 is slidably arranged on the driving track 6.

[0024] Such as Figures 3 - 5As shown, the cover body installation mechanism includes an installation platform 901 and a first lifting cylinder 902. The first lifting cylinder 902 is vertically slidably arranged on the driving track 6. The installation platform 901 is fixedly arranged at the top of the cylinder rod of the first lifting cylinder 902. A limiting groove 903 matching the cover body 702 is arranged on the top surface of the installation platform 901, so that the cover body 702 can be stably embedded in the limiting groove 903, avoiding the offset of the cover body 702 during the upward movement of the installation platform 901 and ensuring the alignment between the cover body 702 and the detection port 701. When the installation platform 901 is directly opposite to the detection port 701, the first lifting cylinder 902 drives the installation platform 901 to move upward until the cover body 702 is clamped with the detection port 701, completing the installation of the cover body 702.

[0025] Furthermore, the cover body installation mechanism further includes a cover body detector 904. The cover body detector 904 is arranged on one side of the bottom of the leakage detection table 5. The detection port of the cover body detector 904 extends obliquely and is directly opposite to the side of the detection port 701 to detect whether there is a cover body 702 on the detection port 701. The inclined arrangement of the detection port of the cover body detector 904 can increase the detection distance of its detection port in the vertical direction, playing a dual auxiliary role. On the one hand, it can detect whether there is a cover body 702 on the detection port 701 before the leakage test to prevent the failure of the leakage test caused by the accidental collision of the cover body 702; on the other hand, it can detect the cover body 702 after the installation of the cover body to ensure that the cover body 702 has been correctly installed.

[0026] The through-hole detection mechanism includes a thimble 10 and a second lifting cylinder 1001. The second lifting cylinder 1001 is vertically slidably arranged on the driving track 6. The thimble 10 is fixedly arranged at the top of the cylinder rod of the second lifting cylinder 1001. The thimble 10 matches the through-hole 102. When the thimble 10 is directly opposite to the through-hole 703, it is judged whether the through-hole 703 is in a conducting state by whether the second lifting cylinder 1001 can drive the thimble 10 to insert into the through-hole 703.

[0027] The second lifting cylinder 1001 and the first lifting cylinder 902 are respectively fixed on both sides of the third connecting block 11. The ejector pin 10 is located between the detection plate 502 and the mounting table 901. The three are switched and docked with the bottom of the product to be tested 7 through the linear movement of the leak detection table 5. Such a result setting can utilize the same driving track 6 to fixedly connect the leak detection table 5 and the third connecting block 11, and then combine and connect the cover body installation mechanism and the through-hole detection mechanism. The leak test, through-hole detection, and cover body installation are sequentially arranged on the driving track 6 according to the processing sequence, and the sequential operation of the three processing procedures is realized through translation switching, ensuring that the through-hole detection is carried out after the leak test is completed, and the cover is sealed in time after the through-hole detection is completed, optimizing the processing flow while ensuring the cleanliness of the internal structure of the product, simplifying the overall processing equipment structure and cost, and improving the overall processing efficiency.

[0028] The driving mechanism includes a first driving cylinder 601 arranged parallel to the driving track 6. The top of the first driving cylinder 601 has a driving block 602 driven by it to move linearly along it. A first connecting block 603 is fixed on the side of the driving block 602, and is fixedly connected to the side of one of the leak detection tables 5 through the first connecting block 603 to drive the two leak detection tables 5 to move linearly along the driving track 6 synchronously. As shown in the illustrated embodiment, the first connecting block 603 is fixedly connected to the side of the leak detection table 5 on the right.

[0029] For the convenience of description, the positions of the leak detection table 5 in the three processes of leak test, through-hole detection, and cover body installation are respectively defined as the "first position", the "second position", and the "third position", that is, when the leak detection table 5 is at the first position, at this time the leak detection table 5 is directly opposite to the detection port 701; when the leak detection table 5 is at the second position, at this time the ejector pin 10 is directly opposite to the through-hole 703; when the leak detection table 5 is at the third position, at this time the mounting table 901 is directly opposite to the detection port 701.

[0030] The first driving cylinder 601 needs to drive the leak detection table 5 fixedly connected thereto to sequentially switch to the first position, the second position, and the third position to respectively implement leak testing, through-hole detection, and installation of the cover body. For convenient positioning, the top of the first driving cylinder 601 has a chute that enables the driving block 602 to move. The two ends of the chute respectively correspond to the first position and the third position of the leak detection table 5. That is, when the driving block 602 is located at the starting end of the movement of the chute, the leak detection table 5 is located at the first position; when the driving block 602 is located at the final end of the movement of the chute, the leak detection table 5 is located at the third position. This can not only use the structure of the chute itself to limit the position of the driving block 602, but also minimize the length of the first driving cylinder 601, avoid space waste, and streamline the equipment structure.

[0031] To limit the leak detection table 5 to the second position, the driving mechanism further includes a second driving cylinder 604 and a guiding slide rail 605 that are on the same straight line as the first driving cylinder 601. A second connecting block 606 driven to move by the second driving cylinder 604 is slidably provided on the guiding slide rail 605. The second connecting block 606 has a convex portion protruding outward from the leak detection table 5. A concave portion is provided at the corner of the leak detection table 5. The convex portion matches the corner of the leak detection table 5, so that the convex portion can block and limit the leak detection table 5 by being clamped with the corner of the leak detection table 5. The second driving cylinder 604 can drive the second connecting block 606 to move, change the position of the second connecting block 606, and then limit the leak detection table 5 to the second position through the second connecting block 606.

[0032] Further, in another feasible embodiment, the leak detection table 5 may need to switch to more than 3 defined positions. More than two mechanisms can also be provided on the third connecting block 11. The second driving cylinder 604 can drive the second connecting block 606 to move and limit the second connecting block 606 to any required position to cooperate with the positions required to be defined by the leak detection table 5 to achieve the switching between different mechanisms.

[0033] A support 101 is erected above the workbench 1 in this solution. A set of the positioning cylinders 2 and the plugging heads 3 are both arranged on the support 101. The setting of the support 101 can facilitate the addition of other required detection equipment, maximize the processing requirements for the same product, simplify the overall processing equipment structure and cost, achieve one-stop processing, and improve the overall processing efficiency.

[0034] In the illustrated embodiment, the bracket 101 is connected with an in-place detector 17 through a connecting rod. The in-place detector 17 is located on one side of the positioning stage 4. The in-place detection sensor 13 is used to detect the components to be arranged on one side of the product 7 to be measured.

[0035] Further, the bracket 101 is also connected with a magnetic detector 16 through a connecting rod. The magnetic detector 16 is located on one side of the positioning stage 4 and faces the side of the product 7 to be measured. Specifically, a spring is arranged inside the product 7 to be measured. The magnetic detector 16 is arranged to detect whether a spring is installed inside the product 7 to be measured. By using the property that the spring is an iron product, the magnetic detector 16 can judge whether a spring is installed by whether there is magnetism.

[0036] In addition, a nut installation mechanism is further arranged on the bracket 101. The nut installation mechanism includes a vertical linear cylinder 13 and a horizontal linear cylinder 14. The top of the vertical linear cylinder 13 is arranged on the bracket 101. The horizontal linear cylinder 14 is arranged at the bottom of the vertical linear cylinder 13. A nut gripper 15 is arranged at the front end of the horizontal linear cylinder 14. After the leak detection is completed, the nut gripper 15 grabs the nut and covers it on the top opening of the product 7 to be measured to ensure the cleanliness inside the product 7 to be measured.

[0037] In addition, the workbench 1 is built inside a frame. A detection screen and other common structures such as sensors to be used are also arranged in the frame. This is the prior art and not the focus of this solution, so it will not be listed one by one here.

[0038] It should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0039] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention. They are not intended to limit the protection scope of the present invention. Any equivalent embodiments or changes made without departing from the technical spirit of the present invention should be included in the protection scope of the present invention.
