Description

Technical Field

[0001] This utility model relates to the technical field of gas seal testing devices, and in particular to a gas seal testing device with high testing efficiency. Background Technology

[0002] An airtightness testing device is a precision instrument used to detect whether there are minute leaks in the casing or sealing structure of a product and to quantify the leakage rate.

[0003] One example of an existing gas tightness testing device is:

[0004] 1. The patent document number is CN209296248U; the patent title is: A Chinese utility model patent for an airtightness testing device;

[0005] 2. The patent document number is CN1103400033B; the patent name is: Chinese utility model patent for a production line type airtightness testing device;

[0006] The aforementioned existing gas tightness testing devices all have the following drawbacks:

[0007] For some products that require an airtight device to cover them for airtightness testing...

[0008] Existing technologies typically require:

[0009] S1: First, grab the product onto the fixture.

[0010] S2: Then send the fixture to the airtightness testing machine.

[0011] S3: Then, the fixture is positioned using sensors or positioning devices.

[0012] S4: Next, the fixture opens the product;

[0013] S5: Finally, the airtight device covers the product for an airtightness test.

[0014] However, in this airtightness test process, step S3 requires repositioning each incoming fixture, which results in low test efficiency; and step S4 requires opening the fixture each time the product is opened and then performing step S5 to test the airtightness of the product, which takes up a certain amount of time and also results in low test efficiency. Utility Model Content

[0015] The purpose of this invention is to overcome the aforementioned defects in the prior art and provide a gas seal testing device with high detection efficiency.

[0016] First: The clamping assembly and the fixing fixture can work together to ensure that the product is placed in the fixing fixture, and the fixing fixture does not require positioning operation time each time;

[0017] Second: The airtight assembly synchronously drives the opening assembly and the airtight head, ensuring that the fixing fixture opens the product synchronously during the airtight head descent detection process, so that the fixing fixture does not need to consume opening operation time each time.

[0018] The first and second points mentioned above make the detection efficiency of the gas seal detection device of this utility model high.

[0019] To achieve the above objectives, this utility model provides a gas seal detection device with high detection efficiency, comprising:

[0020] A material transfer mechanism, which includes a material transfer drive module and a clamping assembly mounted on the material transfer drive module;

[0021] An airtightness testing mechanism is installed on one side of a material transfer mechanism. It includes a machine base, a fixed fixture installed on the machine base, and an airtightness assembly installed above the fixed fixture.

[0022] The clamping assembly cooperates with the fixing fixture, which includes a placement seat, positioning arms mounted on both sides of the placement seat and slidably connected to the placement seat, an elastic element mounted on one end of the positioning arm, and a sliding connector mounted on one side of the positioning arm. The airtight assembly includes a lifting drive module, an airtight head mounted on the lifting drive module, and an opening assembly mounted on one side of the airtight head and cooperating with the two sliding connectors.

[0023] Preferably, the placement seat includes a placement center seat, sliding seats installed at both ends of the placement center seat, and a cover plate installed at one end of the sliding seats. A first sliding groove is provided between the placement seat and the two sliding seats for the positioning arm to slide and connect. The elastic element is installed between the positioning arm and the cover plate.

[0024] Preferably, the top of the two positioning arms is provided with a chamfered portion to facilitate product placement, and the sides of the two positioning arms are provided with limiting portions to facilitate product positioning.

[0025] Preferably, when the clamping assembly lowers the product into the fixing fixture, the clamping assembly presses down to open the two positioning arms.

[0026] Preferably, the placement seat has a second sliding groove on both sides, and the two second sliding grooves correspond one-to-one with two sliding connectors, and the sliding connectors are slidably connected to the second sliding grooves.

[0027] Preferably, the elastic element is a return spring.

[0028] Preferably, the sliding connector includes a connecting rod connected to the positioning arm and a rolling bearing mounted on one end of the connecting rod.

[0029] Preferably, the opening component includes two symmetrically arranged abutment blocks, each corresponding to one of the two sliding connectors. When the airtightness testing mechanism performs airtightness testing on the product, the lifting drive module drives the two abutment blocks and the airtight head to move downwards, so that the two abutment blocks abut against the two sliding connectors and the two positioning arms open, and the airtight head covers the product.

[0030] Preferably, the abutting block includes an abutting portion, a guide opening portion disposed on the top of the abutting portion, and a fully opening portion disposed on the top of the guide opening portion.

[0031] Preferably, the material transfer drive module is a three-axis drive module, and the material clamping assembly is a material clamping cylinder.

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0033] 1. This utility model ensures that the product is placed into the fixed fixture by means of the clamping assembly and the fixed fixture. The fixed fixture is initially positioned. The gas tightness testing device of this utility model does not need to be positioned again when performing gas tightness testing. Each time gas tightness testing is performed, the fixed fixture can be passively opened to allow the product to be placed in the fixed fixture by means of the positioning arm and the elastic element during the process of the clamping assembly placing the product into the fixed fixture. Therefore, the fixed fixture does not need to consume positioning operation time each time, so the testing efficiency is effectively improved.

[0034] 2. This utility model, through the cooperation of an airtight component and a fixing fixture, ensures that the fixing fixture opens the product and the product is covered by the airtight head for airtightness testing. Specifically, the lifting drive module of the airtight component synchronously drives the opening component and the airtight head. During the descent of the opening component, two sliding connectors open, thereby opening the positioning arm connected to the sliding connectors and opening the product. Simultaneously, the airtight head descends to cover the product, thus initiating the airtightness testing. Therefore, the fixing fixture does not require time for each opening operation; the opening of the fixing fixture and the descent of the airtight head for testing can be performed simultaneously, effectively improving testing efficiency.

[0035] 3. The present invention provides a high-efficiency gas seal testing device. Its clamping component only needs to clamp the product onto the fixed fixture for gas seal testing. When the gas seal testing is completed, the clamping component only needs to clamp the product away. In this process, it is not necessary to install a fixture for each product, nor is it necessary to install additional positioning sensors to position the fixture. These two advantages can greatly save manufacturing costs. Attached Figure Description

Detailed Implementation

[0047] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment 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.

[0048] Please see Figures 1 to 8 The present invention provides a gas seal detection device with high detection efficiency, comprising:

[0049] The material transfer mechanism 1 includes a material transfer drive module 11 and a clamping assembly 12 mounted on the material transfer drive module 11;

[0050] The airtightness testing mechanism 2 is installed on one side of the material transfer mechanism 1. It includes a machine base 20, a fixing fixture 21 installed on the machine base 20, and an airtightness assembly 22 installed above the fixing fixture 21.

[0051] The clamping assembly 12 cooperates with the fixing fixture 21. The fixing fixture 21 includes a placement seat 211, positioning arms 212 mounted on both sides of the placement seat 211 and slidably connected to the placement seat 211, an elastic member 213 mounted on one end of the positioning arm 212, and a sliding connector 214 mounted on one side of the positioning arm 212. The airtight assembly 22 includes a lifting drive module 221, an airtight head 223 mounted on the lifting drive module 221, and an opening assembly 222 mounted on one side of the airtight head 223 and cooperating with the two sliding connectors 214.

[0052] The placement seat 211 includes a middle placement seat 2111, sliding seats 2112 installed at both ends of the middle placement seat 2111, and a cover plate 2113 installed at one end of the sliding seats 2112. A first groove 2115 is provided between the placement seat 211 and the two sliding seats 2112 for the positioning arm 212 to slide. An elastic member 213 is installed between the positioning arm 212 and the cover plate 2113.

[0053] The top of the two positioning arms 212 is provided with a chamfered part 2121 to facilitate product placement, and the two positioning arms 212 are provided with limiting parts 2122 on both sides to facilitate product positioning at the front and rear sides.

[0054] The function of the clamping assembly 12 in conjunction with the fixing fixture 21 is as follows: when the clamping assembly 12 lowers the product into the fixing fixture 21, the downward pressure of the clamping assembly 12 will generate downward pressure on the product. The downward pressure of the product acts on the chamfered part 2121 of the two positioning arms 212, which will cause the two positioning arms 212 to receive a horizontal force and move closer along the direction of the elastic member 213. At the same time, the elastic member 213 will contract and the two positioning arms 212 will open, so that the product is placed into the placement seat 211 and is positioned and clamped by the two positioning arms 212. After the product is placed, the clamping assembly 12 will release and leave.

[0055] The placement base 211 has two second sliding grooves 21120 on both sides. The two second sliding grooves 21120 correspond to two sliding connectors 214 respectively. The sliding connectors 214 are slidably connected to the second sliding grooves 21120.

[0056] More specifically, the second groove 21120 is formed on one or both sides of the sliding seat 2112.

[0057] The elastic element 213 is a return spring.

[0058] The sliding connector 214 includes a connecting rod 2141 connected to the positioning arm 212 and a rolling bearing 2142 mounted on one end of the connecting rod 2141. The connecting rod 2141 passes through one side arm or both side walls of the sliding seat 2112, and the connecting rod 2141 is slidably connected to the second slide groove 21120. The rolling bearing 2142 is located on the outside of the sliding seat 2112.

[0059] The opening component 222 includes two symmetrically arranged abutment blocks 2220, which correspond one-to-one with two sliding connectors 214.

[0060] The function of the opening component 222 of the airtight assembly 22 in conjunction with the two sliding connectors 214 of the fixing fixture 21 is as follows: when the airtightness testing mechanism 2 performs airtightness testing on the product, the lifting drive module 221 drives the two abutting blocks 2220 and the airtight head 223 to move downwards respectively, so that the two abutting blocks 2220 abut against the two sliding connectors 214 and the two positioning arms 212 open, and the airtight head 223 covers the product.

[0061] The abutment block 2220 includes an abutment portion 2225, a guide opening portion 2226 provided on the top of the abutment portion 2225, and a fully opening portion 2227 provided on the top of the guide opening portion 2226.

[0062] In this embodiment, the material transfer drive module 11 is a three-axis drive module, and the clamping assembly 12 is a clamping cylinder. The three-axis drive module includes a z-axis drive module 111, a y-axis drive module 112 mounted on the z-axis drive module 111, and an x-axis drive module 113 mounted on the y-axis drive module 112. The clamping assembly 12 is mounted on the x-axis drive module 113. The clamping cylinder consists of a drive cylinder and grippers mounted at both ends of the drive cylinder. The lifting drive module 221 of the z-axis drive module 111, y-axis drive module 112, x-axis drive module 113, and the air-sealing assembly 22 are respectively a slide table, a cylinder, a combination of a cylinder and a slide rail slider (or a guide rod, bushing), a combination of a rotary motor, a synchronous pulley and synchronous belt, and a slide rail slider, or a combination of a rotary motor, a lead screw, and a slide rail slider, or other drive components that drive in a linear manner. In other embodiments, the material transfer drive module 11 is a robotic arm.

[0063] Furthermore, the material transfer mechanism 1 in this embodiment can be upgraded to a synchronous material transfer mechanism 1. That is, based on the original material transfer mechanism 1, several linearly arranged clamping components 12 are installed on the material transfer drive module 11. These several clamping components 12 can complete the clamping of the upper station of the gas seal detection mechanism 2, the gas seal detection mechanism 2, and the lower station of the gas seal detection mechanism 2 in one go.

[0064] An embodiment of this utility model provides a gas seal detection device with high detection efficiency, the working principle of which is as follows:

[0065] S1: The material transfer drive module 11 drives the clamping assembly 12 to clamp the product and bring it above the fixed fixture 21;

[0066] S2: The clamping assembly 12 moves the product downward, causing the product to exert downward pressure on the chamfered portions 2121 of the two positioning arms 212 of the fixing fixture 21. The chamfered portions 2121 of the two positioning arms 212 decompose the downward pressure into horizontal pressure. The horizontal pressure causes the two positioning arms 212 to squeeze the corresponding elastic members 213 respectively. The elastic members 213 retract, causing the two positioning arms 212 to slide backward and open, so that the product can be placed on the placement seat 2111. The product is pressed and positioned by the two positioning arms 212. During this process, the limiting portions 2122 of the two positioning arms 212 ensure the positioning of the front and rear sides of the product.

[0067] S3: When the clamping assembly 12 places the product into the placement seat 2111, the clamping assembly 12 releases the product, and the material transfer drive module 11 drives the clamping assembly 12 to move away from the fixed fixture 21.

[0068] S4: The lifting drive module 221 of the airtight assembly 22 synchronously drives the airtight head 223 and the opening assembly 222 to move downward, which includes the following sub-steps:

[0069] S41: The two abutment blocks 2220 of the opening component 222 correspond to the two sliding connectors 214 one by one. The abutment part 2225 of the abutment block 2220 first contacts the rolling bearing 2142 of the sliding connector 214. Then, the guide opening part 2226 of the abutment block 2220 contacts the rolling bearing 2142 of the sliding connector 214 and slowly pushes the rolling bearing 2142 open, so that the connecting rod 2141 of the sliding connector 214 slides along the second slide groove 21120. The connecting rod 2141 drives the positioning arm 212 to squeeze the corresponding elastic member 213. The elastic member 213 retracts, so that the two positioning arms 212 slide backward and open. Finally, the fully opening part 2227 of the abutment block 2220 contacts the rolling bearing 2142 of the sliding connector 214. At this time, the two positioning arms 212 are in a fully open state, thereby opening the product.

[0070] S42: The airtight head 223 covers the product for an airtightness test.

[0071] One application area of ​​the gas tightness testing device with high detection efficiency according to an embodiment of this utility model is to perform gas tightness testing on micro switch products to ensure the gas tightness and functional reliability of micro switch products.

[0072] The advantages of the gas seal testing device with high detection efficiency according to an embodiment of this utility model are as follows:

[0073] 1. During the process of placing the product into the fixture 21 by the clamping assembly 12, it is not necessary to repeatedly position the fixture 21, which effectively improves the detection efficiency;

[0074] 2. During the opening of the fixture 21 and the lowering of the airtight head 223 to cover the product and conduct the test, the two processes are carried out simultaneously, which effectively improves the testing efficiency.

[0075] 3. The clamping assembly 12 only needs to clamp the product and send it for inspection. It does not require one inspection fixture for each product. At the same time, it does not require the installation of positioning sensors for the inspection fixture. Therefore, the manufacturing cost is reduced.

[0076] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
