[0021] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figures 1 to 2As shown, a socket spring automatic assembly machine of this embodiment includes a frame 1, a fixture turntable 2 rotatably arranged on the frame 1, a spring conveying device 3, a transfer device 4, a socket cover conveying device 5 and a protection door conveying device 6, wherein the spring conveying device 3 is connected to the protection door conveying device 6 to convey the spring into the protection door conveying device 6, the socket cover conveying device 5 and the protection door conveying device 6 are both arranged above the fixture turntable 2 to convey the socket cover to the fixture turntable 2 and assemble the protection door and the spring to the socket cover, and the transfer device 4 is arranged at a position of the frame 1 close to the fixture turntable 2 to transfer the fixture The socket cover assembled on the turntable 2 is transferred to the next station. The spring conveying device 3 includes a storage tank 31, an air inlet 32 ​​and an outlet 33 opened on the storage tank 31. The spring is stored in the storage tank 31. The air inlet 32 ​​is connected to an external air source through an air pipe, and the outlet 33 is connected to the protective door conveying device 6 through a pipeline. When conveying the spring, gas enters the air inlet 32 ​​from the external air source, and blows the spring of the storage tank 31 into the outlet 33. In the process of using the assembly machine of this embodiment, the protective door is first set on the protective door conveying device 6, the spring is placed on the spring conveying device 3, and the socket The seat cover is placed in the socket cover conveying device 5, and then the spring is conveyed to the protection door conveying device 6 through the spring conveying device 3. After being assembled on the protection door, it is conveyed to the socket cover on the clamp turntable 2 through the protection door conveying device 6, so that the automatic assembly of the protection door of the spring can be completed. The socket cover conveying device 5 in this embodiment adopts a combination of a vibration plate, a conveyor belt and a manipulator to realize the grasping and conveying to the clamp turntable 2. In the process of conveying the spring by the above-mentioned spring conveying device 3, high-pressure gas is output to the air inlet 32 ​​through an external air source, and the gas will vibrate the spring in the storage tank 31 The springs are dispersed and then blown into the discharge port 33, so that the feeding of the springs can be realized simply and effectively. At the same time, the feeding process does not require the setting of an additional vibration plate and an external power supply. The storage tank 31 in this embodiment is made of a transparent acrylic round tube, which is convenient for the staff to observe. In order to avoid the occasional accumulation of springs at the discharge port 33, a pressure sensor is added to detect the accumulation phenomenon. Once accumulation occurs, the back-blowing mechanism blows the accumulated springs back into the storage tank 31 from the opposite direction. Thanks to the pipeline material output, the spring conveying device 3 also has the advantage of free installation position, which is not shown in the pipeline diagram.

[0023] As an improved specific implementation method, the air inlet 32 ​​is arranged on the lower end surface of the storage tank 31, and the discharge port 33 is arranged on the upper end surface of the storage tank 31. The air inlet 32 ​​is arranged at the lower end of the storage tank 31, which is used to pass high-pressure gas into the storage tank. The spring is dispersed under the action of the gas to achieve the purpose of avoiding hooking up, and the upward punching method is adopted, so that the impact force of the gas and the gravity of the spring itself can be combined to make the movement of the spring produce a vortex effect, so that the spring has a better dispersion effect, and the gas flow rate directly determines the discharge efficiency and the dispersion effect; the upper opening is used for the discharge port 33, and the inner diameter size of the discharge port 33, the chamfer angle of the nozzle inlet and outlet, and the inner wall roughness and other parameters are repeatedly verified to find the optimal parameters to achieve higher discharge efficiency.

[0024] As an improved specific implementation method, the air inlet 32 ​​includes an air inlet disk 321 and an air inlet connector 322, the air inlet disk 321 is fixed on the lower end of the storage tank 31, the air inlet connector 322 is fixed on the lower end surface of the air inlet disk 321, and is connected to an external air source through an air pipe, and a plurality of air outlet holes 323 are provided on the upper end surface of the air inlet disk 321, and a plurality of the air outlet holes 323 are connected to the air inlet connector 322. By setting a plurality of air outlet holes 323 on the air inlet disk 321, it is possible to realize that the gas filled into the storage tank 31 is multiple streams, so that the vortex motion can be better generated, so that the spring dispersion effect is better.

[0025] As an improved specific implementation, the upper end surface of the air inlet disk 321 is provided with an arc groove 324, and a plurality of air outlet holes 323 are provided on the arc groove 324 and are distributed in a cross shape. Through the setting of the arc groove 324, it can be achieved that the gas has a tendency to gather toward the middle, so that the spring can be better delivered into the outlet 33.

[0026] As an improved specific embodiment, the spring conveying device 3 also includes a secondary feeding mechanism 34, which includes a feeding column 341 and a feeding block 342. The upper end of the feeding column 341 is connected to the discharge port 33 through a pipeline, and a discharge port 343 is provided at the lower end. The discharge port 343 is connected to the protective door conveying device 6 through a pipeline. A fixing hole 344 is provided on the side wall of the feeding column 341. The feeding block 342 is slidably arranged at a position near the feeding column 341, and a fixing rod 345 is fixed on the side facing the feeding column 341. The fixing rod 345 can be slidably The spring is inserted into the fixed material hole 344 to position the spring in the feeding column 341. Since the length of the pipeline for spring transportation is generally set to be long, the spring may be accumulated and stuck in the pipeline during the spring transportation process. The feeding column 341 and the feeding block 342 cooperate with each other to achieve the effect of positioning the spring and then transporting it, so that the spring can be transported out in an orderly manner, thereby avoiding the problem of spring accumulation and getting stuck in the pipeline. In this embodiment, there are two fixed material rods 345 and they are distributed up and down, and the corresponding fixed material holes 344 are provided with two up and down holes, wherein The upper fixing rod 345 is cylindrical, and the lower fixing rod 345 is prismatic. A circular hole is provided on the lower fixing rod 345 for the spring to pass through. A surplus section is left between the circular hole and the end of the fixing rod 345. The fixing hole 344 is adapted to the cross section of the fixing rod 345 to allow the fixing rod 345 to pass through. At the same time, a secondary blowing hole is provided at the unloading port 343. In this way, during the unloading process, that is, after the feeding block 342 slides toward the feeding column 341, the upper fixing rod 345 is inserted into the upper spring to fix the spring, and the circular hole on the lower fixing rod 345 is coaxial with the feeding column 341. That is, relative to the next spring, the next spring falls to the discharge port 343 through the circular hole, and is then sent out through secondary blowing. After the feeding block 342 slides away from the feeding column 341, the upper fixing rod 345 is pulled out from the spring, the spring falls, and the circular hole of the lower fixing rod 345 is transferred, and the surplus section is changed to block the feeding column 341, and the spring falls onto the surplus section, and then the above-mentioned feeding block 342 slides toward the feeding column 341. In this way, through the cooperation of the above-mentioned structure, the effect of conveying the springs one by one can be achieved, so that it can better cooperate with the subsequent protective door conveying device 6 to install the springs.

[0027] Currently, the sockets mainly used in the market have two holes and three holes. Due to the structural differences between the two holes and the three holes, the protection door structures used are also different from each other, so the methods of installing the reset spring are also different. Therefore, this embodiment provides two implementation methods of a two-hole protection door conveying device and a three-hole protection door conveying device.

[0028] Embodiment 1, as Figure 3As shown, a conveying device for a two-hole protective door is provided. The two-hole protective door structure is a rectangular sheet structure. A mounting groove for spring embedding is provided on one side of its long side to realize the installation of the spring, wherein the mounting groove is connected to the lower side of the two-hole protective door. The conveying device is composed of the following parts: a feeding plate vibration plate 61, a feeding plate track 62, a spring installation workbench 63 and a feeding plate manipulator 64, wherein there is a transfer track 65 between the feeding plate track 62 and the spring installation workbench 63, as shown in FIG. Figure 3 As described in the above, the plate feeding track 62, the transfer track 65 and the spring loading workbench 63 form a Z-shaped structure with each other. During the operation, the two-hole protection door is first transported to one end of the transfer track 65 through the plate feeding track 62, and then a two-hole protection door is pushed to the other end of the transfer track 65 by the end cylinder of the transfer track 65, and then the two-hole protection door is pushed to the spring loading workbench 63 by the side cylinder of the transfer track 65, wherein the two-hole protection door is transported to the spring loading workbench 63, and the spring delivered from the discharge port 33 is transported to the spring loading workbench 63 by the cylinder and the push block thereon. The spring is then pushed into the installation groove on the two-hole protective door by the assembly cylinder and the assembly rod under the spring workbench 63, and then the two-hole protective door with the spring installed is grabbed onto the fixture turntable 2 by the grabbing action of the plate feeding robot 64. In this way, the spring installation and transportation of the two-hole protective door are completed. In order to ensure the stability of the installation in this embodiment, a protection door that is flush with the two-hole protection door can be set at the position where the spring is installed to limit the spring during the pushing process to avoid the problem of the two-hole protection door being pushed away due to excessive installation.

[0029] Embodiment 2, as Figure 4 As shown, the general structure of the three-hole protection door conveying device is similar to that of the two-hole protection door, except that there is no transfer track 65 between the plate delivery track 62 and the spring installation workbench 63, but the two are separated from each other, and then a manipulator is added to the plate delivery manipulator 64 to transfer the three-hole protection door on the plate delivery track 62 to the spring installation workbench 63 by grabbing, and then the subsequent steps are the same as above, and the spring is also installed in the spring accommodating hole on the three-hole protection door by the assembly cylinder under the spring installation workbench 63 and the assembly rod. Figure 4 As shown, the plate is then transported to the fixture turntable 2 by the plate feeding robot 64. In this embodiment, the pressure during installation is provided by delaying the transfer of the robot.

[0030] As a specific implementation method of the improvement, Figure 5As shown, the transfer device 4 includes a transfer robot 41 and a flipping mechanism 42. The flipping mechanism 42 is arranged near the fixture turntable 2, and the transfer robot 41 is arranged above the flipping mechanism 42. After the flipping mechanism 42 grabs the socket cover on the fixture turntable 2 and flips it, it is grabbed by the transfer robot 41 and transferred to the next station. Since the socket cover is to be covered on the socket base, and in the process of assembling the spring, it is convenient to install by placing the inner side of the socket cover facing upwards, so when transferring to the next station, the socket cover needs to be flipped. Therefore, through the setting of the flipping mechanism 42, the flipping of the socket cover can be simply and effectively achieved.

[0031] As a specific embodiment of the improvement, the flipping mechanism 42 includes a flipping frame 421, a grabbing table 423 and a flipping robot 422 rotatably mounted on the flipping frame 421, the grabbing table 423 is arranged below the transfer robot 41, and the flipping frame 421 is arranged between the grabbing table 423 and the fixture turntable 2 to grab the socket cover on the fixture turntable 2, and place it on the grabbing table 423 after flipping. Through the setting of the grabbing table 423, a space for placing a flipped socket cover can be provided, so that the transfer robot 41 can better grab and then transfer it to the next workstation.

[0032] As a specific embodiment of the improvement, the flipping robot 422 includes a rotating cylinder 4221 and a claw cylinder 4222, the cylinder body of the rotating cylinder 4221 is fixed on the flipping frame 421, the cylinder body of the claw cylinder 4222 is fixed on the rotating shaft of the rotating cylinder 4221, the claw head of the claw cylinder 4222 includes a left clamping rod, a right clamping rod and a compression spring rod, one end of the compression spring rod is fixed on the cylinder body of the claw cylinder 4222, and the other end extends to a position above the left clamping rod and the right clamping rod, so that when the left clamping rod and the right clamping rod clamp the socket cover, the spring and the protective door on the socket cover are pressed, and through the combined action of the rotating cylinder 4221 and the claw cylinder 4222, the effect of clamping the socket cover and then flipping it can be simply and effectively achieved, and through the setting of the compression spring rod, the spring on the socket cover can be pressed to avoid the problem of the spring on the socket cover popping out during the flipping process.

[0033] As an improved specific implementation, a slide rail 4231 is provided under the grabbing platform 423, and the grabbing platform 423 can be slidably set on the slide rail 4231. One end of the slide rail 4231 is under the transfer robot 41, and the other end extends to under the claw head of the air claw cylinder 4222 after flipping. A sliding cylinder 4232 is installed on one side of the flipping frame 421, and the push rod of the sliding cylinder 4232 is fixed to the grabbing platform 423 to drive the grabbing platform 423 to slide back and forth on the slide rail 4231. Through the setting of the slide rail 4231, the effect of the grabbing platform 423 being able to slide can be achieved. In this way, through the sliding of the grabbing platform 423, the stroke of the transfer robot 41 can be separated from the stroke of the air claw cylinder 4222, thereby increasing the stability of the overall operation of the device.

[0034] To sum up, the socket spring automatic assembly machine in this embodiment can realize spring feeding through high-pressure gas by setting the spring device 3 as a storage tank 31, an air inlet 32 ​​and a discharge port 33, so that the connected springs can be effectively broken up, thereby avoiding the problem of spring connection.
