Description

Technical Field

[0001] The utility model relates to the technical field of airtight machine production equipment, in particular to a track linkage device for an airtight machine. Background Art

[0002] In the current industrial production environment, airtight machines, as a key testing equipment, are widely used in various scenarios where product sealing performance needs to be ensured. With the continuous improvement of social needs and information technology, the market demand for products and performance is also gradually increasing, especially in the production process of automotive parts, which requires both production efficiency and the improvement of airtightness testing requirements of parts. With the improvement of testing requirements, the structure of airtight machines is more complicated, and the testing process also involves multiple steps of operation, making the operation of airtight machines cumbersome during the testing process, requiring multiple operators to work together.

[0003] In addition, since the inspection process of the airtight machine mainly involves sending the workpiece into the inspection equipment first, maintaining the pressure for a period of time for airtightness testing, and then sending the workpiece out after completion, the structural design of the airtight machine is equipped with a feed port for sending the workpiece in and out to meet the requirements, while also reducing the volume occupied by the equipment and ensuring the inspection function of the airtight machine. However, in actual application, due to the complex operation of the airtight machine, when multiple operators operate at the same time, it is easy to cause confusion between inspected and uninspected workpieces, and mixed loading, etc. In order to avoid confusion, only single workpieces can be inspected in turn, but this leads to a long operation cycle, discontinuous production, and low production efficiency. In addition, during the inspection process, the workpiece needs to be sent into the equipment first and then sent out, and the equipment operation cycle is long, affecting the overall production efficiency.

[0004] Therefore, in view of the problems that the existing airtight machine detection operation process is complicated, the manpower requirement is large, and the production efficiency is low, an airtight machine track linkage device is now provided. Utility Model Content

[0005] The utility model aims to provide a track linkage device for an airtight machine, so as to solve the problems in the prior art that the airtight machine has a complicated operation process, large manpower requirements, and is easy to mix and affect production efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an airtight machine track linkage device, which connects the front and rear ends of the airtight machine equipment and sets a workbench and an inspection table at the rear end, so that the transmission and workpiece adsorption are linked, realizing one-way flow operation of the workpiece, avoiding mixed loading, reducing the round-trip operation time, and improving production efficiency. Specifically, it includes an airtight machine body, on which a one-touch control button is arranged, and the airtight machine body includes a feed end, a detection chamber and a discharge end arranged in sequence; a slide rail assembly is arranged at the feed end, one end of the slide rail assembly extends to the outside of the front end of the airtight machine body, and the other end extends into the detection chamber and is connected to the discharge end; a test mold for placing workpieces is arranged on the slide rail assembly; an airtight detection mechanism is arranged in the detection chamber, and the airtight detection mechanism is located above the test mold; the airtight detection mechanism includes a cylinder, and a pressure plate connected to the cylinder, on which a plurality of suction cup assemblies for sucking up and holding the workpieces on the test mold are arranged, and the suction cup assembly and the slide rail assembly operate synchronously; the height of the suction cup assembly is 100-130mm; a workbench is arranged at the discharge end, one end of the workbench extends to the outside of the rear end of the airtight machine body, and the other end is connected to the slide rail assembly; an inspection table is arranged on the workbench, one end of the inspection table is movably arranged on the slide rail assembly, and the other end is movably arranged on the workbench; a buffer layer is arranged on the inspection table.

[0007] The principles and advantages of this solution are:

[0008] During the use of the airtight machine, due to the limitations of the detection principle and detection process of the airtight machine, it is believed that as long as the workpiece can be sent into the airtight machine to complete the inflation and pressure maintenance process, and then the workpiece can be sent out. Although in most inspection operations on parts, this is the process of sending in and out, in the actual production process, we ignore that the airtightness inspection of workpieces is often continuous and large-scale, resulting in the need to wait for the workpiece to enter and exit, take the workpiece, and then put it on for inspection during the use of the airtight machine. This operation process did not make us realize that it is actually a repetitive operation process that affects the production rhythm. In addition, it is not easy to carry large parts. Storing workpieces on the same side is also prone to the risk of mixed loading, increasing the workload and labor intensity of operators.

[0009] After realizing this problem, this solution breaks away from the inherent mode of the airtight machine operation process. Instead, the front and rear ends of the airtight machine are connected, and the workbench and slide rail components are connected to enable the workpiece to be operated in a one-way flow mode to avoid the risk of mixed loading of workpieces. The transmission, adsorption, and inspection are carried out simultaneously, thereby reducing the need to carry workpieces and the repeated operation process of picking up and then loading them. The production cycle of airtight detection of a single workpiece is effectively shortened, production efficiency is greatly improved, one-button control is achieved, the operation process is simplified, and manpower requirements are reduced, while ensuring the stability and safety of detection.

[0021] Embodiment 1

[0022] This embodiment is basically as shown in the attached Figure 1As shown, an airtight machine track linkage device in this embodiment connects the front and rear ends of the airtight machine, sets a suction cup structure to ensure the adsorption of the workpiece, and makes the transmission and adsorption proceed synchronously to change the running direction of the workpiece, realize one-way flow operation, avoid mixed loading and improve production efficiency at the same time. This scheme breaks away from the inherent stereotyped operation mode of the airtight machine, overcomes the technical prejudice that the airtight machine can only be operated on one side, and effectively improves the detection efficiency of the airtight machine. Specifically, this scheme includes an airtight machine body 1, and a one-button control button is installed on the airtight machine body 1. The one-button control button is electrically connected to the controller. By operating the one-button control button, the two-handed operation of two people in the prior art is changed to a one-button start operation, which reduces manpower input, simplifies the operation process, and is more convenient and quick. At the same time, because the operation mode of synchronous linkage of transmission and adsorption is adopted in this scheme, the control process is simplified, so a one-button start operation can be realized, which improves the convenience of operation.

[0023] As attached Figure 1 As shown, the airtight machine body 1 includes a feed end 2, a detection chamber 3 and a discharge end 4 which are arranged in sequence from the front end to the rear end. The workpiece is fed in from the feed end 2, and after completing the airtightness test in the detection chamber 3, it is directly sent out from the discharge end 4 for inspection without turning back, thereby realizing unidirectional flow of the workpiece, avoiding mixed loading and improving production efficiency.

[0024] As attached Figure 2 As shown, a slide rail assembly 5 is installed at the feed end 2 by bolts, one end of the slide rail assembly 5 extends to the outside of the front end of the airtight machine body 1, and the other end extends into the detection chamber 3 and is connected to the end of the discharge end 4. The slide rail assembly 5 includes a support frame 6 with an overall square structure, the support frame 6 is welded to the outer shell of the airtight machine body 1, and four slideways 7 extending to the inside of the detection chamber 3 are installed side by side in the support frame 6. Figure 3 As shown in FIG. 1 , a test mold 8 is installed on the slideway 7 and can slide forward and backward along the slideway. The test mold 8 is used to place the workpiece to be tested and send the workpiece to be tested into the detection chamber 3. Figure 3 , Attachment Figure 4 As shown, four groups of slide grooves 21 respectively matched with four slideways 7 are installed at the bottom of the test mold 8, and the test mold 8 is driven to move on the slideway 7 through the slide grooves 21.

[0025] As attached Figure 1 and attached Figure 5 As shown, an airtight detection mechanism 22 is installed in the detection chamber 3. The airtight detection mechanism 22 is installed as a whole on the upper part of the detection chamber 3. When the test mold 8 is sent into the detection chamber 3, the airtight detection mechanism 22 is located above the test mold 8 to detect the workpiece to be tested. In this embodiment, as shown in the attached Figure 5As shown, the airtight detection mechanism 22 includes a cylinder electrically connected to the controller, and a pressure plate 9 installed at the lower end of the cylinder. A plurality of suction cup assemblies 10 are installed on the pressure plate 9 to suck up and hold the workpiece on the test mold 8. The suction cup assembly 10 operates synchronously with the slide rail assembly 5. When the suction cup assembly 10 sucks up the workpiece, the test mold 8 follows the slide 7 from the feed end 2 to load the next workpiece to be tested. In this embodiment, the height of the suction cup assembly 10 is set to 100-130mm. Due to the complex internal structure of the airtight machine, the suction cup assembly 10 needs to have sufficient suction to ensure that the workpiece is stably adsorbed and will not fall off, and at the same time, it cannot affect the detection function of the airtight machine. Therefore, the position and size setting of the suction cup assembly 10 is very important.

[0026] As attached Figure 6 The suction cup assembly 10 shown includes four groups in total, which are installed side by side at the lower end of the pressure plate 9 from left to right, including the first suction cup assembly 11, the second suction cup assembly 12, the third suction cup assembly 13 and the fourth suction cup assembly 14 from the left. In this embodiment, the distance between two adjacent groups of suction cup assemblies 10 is set to 30-40mm; to ensure that the adsorption of most specifications of workpieces can be met, improve versatility, and at the same time ensure the uniformity of the adsorption force points, improve the stability of the workpiece after adsorption, and avoid the workpiece from falling and damaging the workpiece.

[0027] As attached Figure 7As shown in the enlarged view of part A, the suction cup assembly 10 includes a pressure rod 15 vertically installed at the lower end of the pressure plate 9, and a suction cup 16 connected to the bottom of the pressure rod 15. The suction cup 16 is electrically connected to the vacuum generator through the pressure rod 15 wiring, and the vacuum generator generates suction, so that the workpiece is adsorbed on the suction cup 16. In order to ensure the grip of the suction cup 16 and the stability after adsorption, in this embodiment, the suction cup 16 is set as a circular suction cup with a diameter of 60-100mm, so that the contact between the suction cup 16 and the workpiece is more closely fitted. Among them, the first suction cup assembly 11 and the fourth suction cup assembly 14 on the far right have the same structural setting, and the second suction cup assembly 12 in the middle has the same setting as the third suction cup assembly 13. Taking the first suction cup assembly 11 as an example, the first suction cup assembly 11 includes four pressure rods 15 arranged in parallel and suction cups 16 correspondingly installed at the lower ends of the pressure rods 15. The second suction cup assembly 12 and the third suction cup assembly 13 respectively include two parallel pressure rods 15 and suction cups 16 installed at the lower ends of the pressure rods 15. Due to the large size of the workpiece, the two sides are more likely to shake during adsorption, resulting in unstable factors, resulting in loose adsorption of the workpiece. It is easier to adsorb the workpiece after fixing the outside of the workpiece first, and from the perspective of the force applied to the object, it is easier to operate and more labor-saving to pick up the object from the outside. Therefore, four suction cup assemblies 10 are correspondingly arranged on both sides of the pressure plate 9, and two suction cup assemblies 10 are arranged in the middle as a center for stability, which can not only meet the suction force required for adsorbing the workpiece, but also reduce the number of suction cup assemblies 10 as much as possible in a limited space, which is more convenient for production and installation, and ensures the stability of the suction cup grasping.

[0028] Combined with Figure 8 As shown, a workbench 17 is welded at the discharge end 4, one end of the workbench 17 extends to the outside of the rear end of the airtight machine body 1, and the other end is connected to the slide rail assembly 5. In this embodiment, the length of the workbench 17 is set to 1.5m to meet the inspection operations and packaging of the work, while minimizing the occupied volume of the equipment as much as possible.

[0029] An inspection table 18 is installed on the workbench 17. One end of the inspection table 18 is movably installed on the slide rail assembly 5, and the other end is movably arranged on the workbench 17. Fig. 9 As shown, one end of the inspection table 18 is connected to the test mold 8, and synchronous forward and backward displacement is achieved by linkage with the test mold 8. When the test mold 8 is opened, the inspection table 18 can be just located under the adsorbed workpiece, and the workpiece is received and sent out from the discharge end 4. A sliding wheel 19 is installed below the other end of the inspection table 18, and the sliding wheel 19 slides back and forth on the workbench 17, and the sliding wheel 19 cooperates with the forward and backward movement of the inspection table 18. In this embodiment, a buffer layer 20 is also attached to the inspection table 18, and the buffer layer 20 is set to a sponge layer with a length of 1800-2500mm, a width of 1500-1800mm, and a height of 30-50mm, so as to play a buffering role for the fallen workpiece, avoid damage to the workpiece, and ensure the quality of the workpiece.

[0030] The specific implementation process is as follows:

[0031] As attached Figure 1 To Attachment Fig. 9 As shown, when conducting air tightness test on large workpieces such as automobile trunk lids (weight 9KG and above), first install the side of the airtight machine track linkage device against the wall horizontally in the production site (the airtight machine in the prior art is open on one side, similar to the present solution with only a feed end, so the rear end is generally placed against the wall longitudinally) to facilitate unidirectional flow along the production process. Then debug the test mold 8 to the initial loading position, even if the test mold 8 is located at the front end of the feed end 2, place the workpiece to be tested on the test mold 8, press the one-button start button, and the test mold 8 will carry the workpiece to be tested along the slide 7 into the airtight machine detection chamber 3. When the test mold 8 reaches the designated detection position, the airtight detection mechanism is driven by the cylinder to press downward, and the inside of the workpiece to be tested is inflated and pressure maintained for 90 seconds.

[0032] After the test is completed without any abnormality, the pressure plate 9 is lifted up by the drive of the cylinder, and the vacuum generator generates suction at the same time, so that the suction cup assembly 10 sucks up and holds the workpiece to be tested. At this time, the conveying and adsorption are carried out simultaneously. While the workpiece is sucked up, the slide 7 drives the test mold 8 to move toward the feed end 2, and the test mold 8 drives the inspection table 18 connected thereto to move into the test chamber 3. When the inspection table 18 reaches the specified position and the buffer layer 20 is facing the workpiece to be tested, the suction cup assembly 10 puts down the workpiece to be tested and makes the workpiece to be tested fall on the buffer layer 20. At the same time, the test mold 8 returns to the initial loading position, and the operator places the next workpiece to be tested on the test mold 8. When the test mold 8 enters the test chamber 3 again along the slide 7, it will drive the loaded inspection table 18 to slide out from the discharge end 4. At this time, the operator can check and pack the tested workpiece at the discharge end 4, and at the same time, the test chamber 3 synchronously completes the next round of air tightness testing, and the cycle continues.

[0033] In this embodiment, by jumping out of the inherent operation mode of the airtight machine detection, the technical prejudice that the airtight machine detection end is in a closed state due to the airtight machine detection process of inflation and pressure maintenance is overcome. This solution is to find that the airtight machine detection process is mainly to inflate and pressure maintain the inside of the workpiece, and the structure inside the external operation equipment has no effect on the detection effect. In addition, the existing airtight machine is designed as a structure with one side open. The purpose is that in the design of a single device, only the airtight machine detection operation process is considered to be sending the workpiece into the device for inflation and pressure maintenance, and then sending the workpiece out to complete the detection. Setting an open feeding end can fully meet the operation requirements of the detection equipment, and this structure also reduces the size and space occupied by the equipment. However, in the actual production operation process, we ignore the fact that the workpieces that need to be inspected are often not single, but continuous and large-scale. This leads to the fact that in the actual inspection process, the operation procedures of the single-side inlet and outlet are numerous and complicated, which can easily lead to problems such as mixed loading. In addition, because it is necessary to wait for the workpieces to enter and exit, the inspection cycle of an airtight machine for a single workpiece is about 155 seconds, which greatly affects production efficiency. At the same time, it also places higher requirements on operators, requiring more concentration and labor.

[0034] In this embodiment, the two ends of the airtight machine are connected and a discharge end is set so that the test mold 8, the inspection table 18, and the suction cup assembly 10 can be synchronized, reducing the transportation action of the workpiece from the test mold to the inspection table, and saving the process of first taking the workpiece and then loading it, thereby realizing one-way flow operation of the workpiece and realizing an operation mode that can be started by one-button control, simplifying the operation process, reducing the production cycle to 122 seconds, and effectively improving production efficiency by 21%. At the same time, it can also avoid the risk of mixed loading, effectively reduce manpower requirements, improve production efficiency and reduce production costs.

[0035] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
