Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a device for assembling and sealing rubber rings. Background Technology

[0002] Rubber seals, as an important component of industrial production, have the following advantages:

[0003] (1) It is elastic and resilient;

[0004] (2) Appropriate mechanical strength, including tensile strength, elongation and tear resistance.

[0005] (3) It has stable performance, does not easily swell in the medium, and has a small thermal shrinkage effect (Joule effect).

[0006] (4) It is easy to process and shape, and can maintain precise dimensions.

[0007] (5) It does not corrode the contact surface or contaminate the medium.

[0008] Due to these advantages, rubber seals are widely used in the manufacturing of various industries such as automobiles, food, and pharmaceuticals.

[0009] With increasingly widespread applications and diverse workpiece shapes, the assembly of rubber sealing rings has become a difficult problem to be solved in product manufacturing, and the demand for reliable and efficient sealing ring assembly equipment is becoming more and more urgent.

[0010] During the assembly of automotive gear position sensors, rubber sealing rings need to be installed. Due to the irregular shape of the sensor and the softness of the sealing ring, the traditional method of assembling the sealing ring can only be done manually by inserting it into the corresponding groove of the workpiece. During installation, workers manually put the sealing ring into the material. Because the sealing ring is soft and has a certain deformation, the height of the sealing ring is uneven after installation. This not only looks bad but also affects the subsequent sealing test function. This method of manually assembling the sealing ring is not only labor-intensive for workers but also has low assembly efficiency. Summary of the Invention

[0011] In view of the shortcomings or deficiencies of the prior art, the present invention provides a rubber ring assembly and sealing test equipment that can not only reduce the labor intensity of workers and improve assembly efficiency, but also ensure sealing performance.

[0012] A rubber ring assembly and sealing test equipment includes: a worktable, an automatic rubber ring forming mechanism, an automatic workpiece picking mechanism, and a sealing test mechanism;

[0013] The automatic rubber ring take-up mechanism includes a single-axis robot, a take-up mechanism linear guide, a lifting cylinder, a push ring rod, a take-up block, and a positioning shaft;

[0014] The number of positioning shafts is multiple, and the automatic rubber ring forming mechanism is fixed above the worktable by multiple positioning shafts;

[0015] The forming mechanism has multiple linear guides distributed in different directions on the horizontal plane;

[0016] The number of single-axis robots is the same as the number of linear guide rails of the forming mechanism, and they are respectively set on multiple linear guide rails of the forming mechanism.

[0017] The number of the take-up blocks is the same as the number of the single-axis robots, and they can be replaced on the linear guide rail of the take-up mechanism. The movement speed and position are precisely controlled by the single-axis robots.

[0018] The push ring top rod is arranged perpendicularly to the forming block and is located above the lifting cylinder, and moves up and down reciprocally through the lifting cylinder;

[0019] The automatic workpiece picking mechanism includes a fixed base, a lifting cylinder assembly mounted on the fixed base, a product picking head, a Z-axis linear guide rail for the picking mechanism, a limit buffer assembly, a transverse cylinder assembly, and an X-axis linear guide rail for the picking mechanism.

[0020] The mounting base is fixed to the workbench;

[0021] The product picking head reciprocates up and down along the Z-axis linear guide rail of the picking mechanism via the lifting cylinder assembly, and reciprocates horizontally along the X-axis linear guide rail of the picking mechanism via the transverse cylinder assembly;

[0022] The limiting buffer assembly is located above both ends of the X-direction linear guide rail of the picking mechanism, limiting the moving endpoint of the product picking head;

[0023] The sealing test mechanism can be replaced and installed on the workbench, and its inner cavity shape is consistent with the shape of the workpiece.

[0024] Furthermore, there are multiple push ring push rods, and the shape they form is smaller than the bottom surface of the rubber ring.

[0025] Optionally, the number of push ring push rods is one, and the top surface of the push rod is smaller than the bottom surface of the rubber ring.

[0026] The beneficial effects of this invention are:

[0027] 1. The equipment of the present invention can not only adapt to products with irregular shapes and quickly and reliably install the sealing ring, but also integrates a sealing test function, thus meeting the assembly and testing requirements of the product.

[0028] 2. The equipment of the present invention adopts a quick-change fixture design, which can meet the production needs of different products by changing the fixture, thereby saving production costs and improving efficiency. Attached Figure Description

Detailed Implementation

[0034] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0035] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0036] like Figure 1 The shown rubber ring assembly and sealing test equipment comprises a worktable 100, an automatic rubber ring forming mechanism 200, an automatic workpiece picking mechanism 300, and a sealing test mechanism 400. The sealing ring is manually placed on the automatic rubber ring forming mechanism 200, the safety light curtain is withdrawn, and the tail switch is activated. The forming block 250 then forms the sealing ring. The workpiece is manually placed on the fixture. The product picking head 320 descends to press the workpiece firmly, and the lifting cylinder 230 extends to assemble the rubber ring into place before retracting. After the automatic workpiece picking mechanism 300 rises and scans the workpiece's barcode, the workpiece is placed in the sealing test mechanism 400 for leakage testing.

[0037] like Figure 2The automatic rubber ring take-up mechanism 200 shown consists of four take-up blocks 250 in four directions. Each take-up block 250 is driven by a single-axis robot 210 in a different direction, and the linear guide rail 220 of the take-up mechanism provides precise guidance. The single-axis robot 210 controls the travel stroke and running speed to ensure that the rubber ring is subjected to uniform force during take-up. After take-up, the lifting cylinder 230 extends and drives the retraction push rod 240 to push the rubber ring into the workpiece. The automatic rubber ring take-up mechanism 200 is connected to the worktable 100 via the positioning shaft 260.

[0038] like Figure 3 The workpiece automatic picking mechanism 300 shown is described. The product picking head 320 moves in the Z-axis direction via the Z-axis linear guide 370 and the lifting cylinder assembly 310. The lateral movement cylinder assembly 360 and the X-axis linear guide 330 enable the lateral movement of the product picking head 320. The product picking head 320 performs the clamping function on the workpiece. All of the above mechanisms are fixed to the fixed base 340 via their respective connecting parts, and then mounted on the worktable 100 via the fixed base 340.

[0039] like Figure 4 The main components of the rubber ring assembly and sealing test equipment shown are fixed to the worktable plate through their respective connection methods, so as to achieve a unified positioning benchmark for the components.

[0040] The sealing test mechanism 400 includes a quick-change sealing connector, a vacuum generator, and testing instruments, which are fixed to the worktable by test fixtures. After the workpiece is in place, the vacuum generator evacuates the test chamber to the rated vacuum level and then begins pressure holding. The testing instruments monitor the pressure changes during the pressure holding period, and output the final value after the time stops. The program automatically determines whether it is qualified.

[0041] The equipment of this invention has a barcode scanning function, enabling workpiece traceability. The equipment also features a safety light curtain, reliably ensuring operator safety. Workpiece inspection at each stage of the process prevents the possibility of omissions or misassemblies.

[0042] The above description is merely an embodiment of the present invention. Commonly known structures and characteristics of the solutions are not described in detail here. It is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Several modifications and improvements can be made without departing from the present invention, and these should also be considered within the scope of protection of the present invention. These modifications will not affect the effectiveness of the present invention or the practicality of the patent.
