[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 10As shown, the present invention provides an automatic assembly device for a car thermostat valve core, comprising a base 1, an operating table 2 is fixedly installed on the top of the base 1, a material storage table 3 is fixedly installed on the side of the top of the base 1 away from the operating table 2, a mechanical arm 4 is fixedly installed on the other side of the top of the base 1 away from the operating table 2, a cleaning component 5 is fixedly installed on one end of the mechanical arm 4, a third fixed cylinder 6 is fixedly installed on the bottom of the cleaning component 5, a first limiting cylinder component 9 is movably sleeved inside the third fixed cylinder 6, a second limiting cylinder component 10 is movably sleeved inside the first limiting cylinder component 9, a supporting component 11 is movably sleeved inside the second limiting cylinder component 10, a transmission component 7 is movably installed in an annular manner at equal angles inside the second limiting cylinder component 10, a fixing component 8 is fixedly installed in an annular manner at equal angles on the inner wall of the second limiting cylinder component 10 located at the bottom of the transmission component 7, and the internal structures of the third fixed cylinder 6, the first limiting cylinder component 9 and the second limiting cylinder component 10 are consistent.

[0032] The automobile thermostat valve core parts are placed inside the storage platform 3, and the program controls the mechanical arm 4 to drive the cleaning component 5 to maintain verticality with the automobile thermostat valve core parts inside the storage platform 3, and at the same time press the cleaning component 5 downward, so that the support component 11 is blocked by the automobile thermostat valve core parts, so that the support component 11 moves upward, and the transmission component 7 is pulled during the movement of the support component 11, and the top of the support component 11 is separated from the top of the second limiting cylinder component 10, and the automobile thermostat valve core parts enter the second limiting cylinder component 10, and the fixing component 8 is driven by the transmission component 7 to rotate to clamp and fix the automobile thermostat valve core parts inside the second limiting cylinder component 10, thereby improving the stability of the automobile thermostat valve core parts grabbing;

[0033] After the automobile thermostat valve core parts are grabbed and fixed, the cleaning component 5 is started, and the gas inside the cleaning component 5 is injected into the second limiting cylinder component 10, and is ejected through the second limiting cylinder component 10 and the support component 11 respectively. The ejected gas passes through the parts clamped inside the second limiting cylinder component 10, so that the dust on the surface of the automobile thermostat valve core parts is cleaned by wind, thereby improving the assembly quality of the automobile thermostat valve core;

[0034] At the same time, due to the different diameters of the automobile thermostat valve core components, the larger components push the second limit cylinder assembly 10 or the first limit cylinder assembly 9 to move upward, and are fixed by the transmission assembly 7 and the fixing assembly 8 with components of different sizes, so that different components of the automobile thermostat valve core can be grabbed.

[0035] like Figure 4 , Figure 7As shown, the first limiting cylinder assembly 9 includes a first fixed cylinder 901, which is movably sleeved inside the third fixed cylinder 6, and a first sealing plate 902 is fixedly installed on the outside of the top of the first fixed cylinder 901. The outer diameter of the first sealing plate 902 is consistent with the outer diameter of the top of the third fixed cylinder 6, and the first sealing plate 902 is in contact with the top of the third fixed cylinder 6.

[0036] When the robot arm 4 is used to grab a component with a larger diameter of the automobile thermostat valve core, due to the larger diameter of the component, the first fixed cylinder 901 remains vertical and presses down on the component, and the first fixed cylinder 901 is blocked by the component and moves upward. The component is located inside the third fixed cylinder 6, and the first sealing plate 902 is separated from the top of the third fixed cylinder 6. At the same time, when the first sealing plate 902 moves upward, it pulls the transmission assembly 7 inside the third fixed cylinder 6, and at the same time, the fixed assembly 8 inside the third fixed cylinder 6 is pulled by the transmission assembly 7 to clamp and fix the component inside the third fixed cylinder 6, so that components with different diameters can be grabbed, thereby improving the practicality of the robot arm 4.

[0038] After the automobile thermostat valve core parts are fixed by the fixing assembly 8, the cylinder 502 is started to push the transmission plate 504 downward. Since the transmission plate 504 and the fixed shell 501 are in a sealed structure, the gas inside the fixed shell 501 is squeezed during the downward movement of the transmission plate 504, and the air pressure at the lower end of the fixed shell 501 gradually increases. At the same time, since the top of the third fixed cylinder 6 is in an open state, and the tops of the first limiting cylinder assembly 9 and the second limiting cylinder assembly 10 are in a closed state, the gas enters the third fixed cylinder 6 respectively. At this time, the second one-way valve inside the jet hole 103 on the inner wall of the third fixed cylinder 6 is opened, and the gas is ejected through the jet hole 103 respectively and moves downward between the third fixed cylinder 6 and the first fixed cylinder 901. During the movement, the surface of the parts in the third fixed cylinder 6 is cleaned, thereby improving the assembly quality of the automobile thermostat valve core parts.

[0039] After the transmission plate 504 is pushed out, the cylinder 502 retracts the transmission plate 504, and the transmission plate 504 moves upward. The two first one-way valves 506 are in an open state, and the external gas enters the lower end of the fixed shell 501 through the connecting hole 503 and the air inlet hole 505, and can continue to be circulated.

[0041] The support assembly 11 includes a fixed rod 111, which is movably connected to the inside of the second fixed cylinder 101. A third sealing plate 112 is fixedly installed on the outside of the top of the fixed rod 111. The bottom of the third sealing plate 112 is provided with a sliding groove 113 at an equal angle in an annular manner. The third sealing plate 112, the second sealing plate 102 and the first sealing plate 902 have the same structure.

[0042] The robot arm 4 is started through program control to grab the parts inside the storage platform 3, the fixing rod 111 is kept vertical to the automobile thermostat valve core parts and pressed down, after the fixing rod 111 is blocked, the fixing rod 111 drives the third sealing plate 112 during the upward movement, the bottom of the third sealing plate 112 is separated from the top of the second fixed cylinder 101, the top of the second fixed cylinder 101 is in an open state, and the parts are located inside the second fixed cylinder 101, and at the same time, during the upward movement of the second sealing plate 102, the transmission assembly 7 and the fixing assembly 8 are pulled, the parts inside the second fixed cylinder 101 can be fixed by the fixing assembly 8, and then the dust on the surface of the automobile thermostat valve core parts can be cleaned by the cleaning assembly 5.

[0043] like Figure 5 , Figure 6 , Figure 8As shown, the transmission assembly 7 includes a sliding block 702, the sliding block 702 is slidably engaged in the interior of the sliding groove 113, the bottom of the sliding block 702 is fixedly installed with a first transmission rod 701, the bottom of the first transmission rod 701 is fixedly installed with a first connecting block 703, the top of the first connecting block 703 is hinged with a first transverse rod 704, the bottom of the first connecting block 703 is hinged with a second transverse rod 708, one end of the second transverse rod 708 is fixedly installed with a contact block 707, the first transverse rod 704 A second transmission rod 706 is hinged to one end of the second transverse rod 708, and a limiting block 705 is fixedly installed on one side of the second transmission rod 706. A limiting groove 709 is provided on the inner side of the inner wall of the second fixed cylinder 101, and the limiting block 705 is slidably engaged in the inside of the limiting groove 709. A first baffle 710 is fixedly installed on the inner wall of the second fixed cylinder 101 away from the top of the limiting groove 709, and a second baffle 711 is fixedly installed on the outer side of the inner wall of the second fixed cylinder 101 at the bottom of the second transverse rod 708.

[0044] The fixing rod 111 is kept vertical with the automobile thermostat valve core component and pressed down. After the fixing rod 111 is blocked, the fixing rod 111 drives the third sealing plate 112 in the process of moving upward. In the process of the third sealing plate 112 moving upward, the first connecting block 703 is pulled upward through the sliding block 702 and the first transmission rod 701, and the first transverse rod 704 and the second transverse rod 708 are driven respectively. Since the limiting block 705 is slidably engaged in the limiting groove 709, the second transmission rod 706 is limited by the limiting groove 709. During the upward movement of one end of the first transverse rod 704, the other end of the first transverse rod 704 moves downward and pushes the second transmission rod 706 under the limitation of the first baffle 710 and the second transmission rod 706, and the limiting block 705 slides downward inside the limiting groove 709. At the same time, the sliding block 702 slides inside the sliding groove 113. During the downward movement of the second transmission rod 706, it pushes the second transverse rod 708, and the contact block 707 pushes the fixing assembly 8 to rotate at the hinge, so that the parts can be clamped and fixed by the fixing assembly 8.

[0045] like Figure 6 As shown, the fixing assembly 8 includes a clamping block 801, which is fixedly installed on the inner wall of the second fixed tube 101, and sealing covers 802 are fixedly installed on the top and bottom of both sides of the clamping block 801, and one end of the two sealing covers 802 is fixedly connected to the inner wall of the second fixed tube 101, and the two sealing covers 802 are made of rubber material and are corrugated. A spring 804 is fixedly installed on one side of the clamping block 801, and a rubber pad 803 is fixedly installed inside the clamping block 801.

[0046] By rotating one end of the second transverse rod 708, the contact block 707 contacts one side of the upper end of the clamping block 801, and the second transverse rod 708 continues to rotate, pushing the clamping block 801 to rotate at the hinge and stretching the spring 804. The other side of the lower end of the clamping block 801 contacts the outside of the automobile thermostat valve core component, and the center rod of the automobile thermostat valve core component can be fixed by one side of the lower end of the clamping block 801.

[0047] like Figure 6 , Figure 8 As shown, the first transverse rod 704, the second transverse rod 708, the first connecting block 703 and the second transmission rod 706 are rectangular, the clamping block 801 is inclined at fifteen degrees, one end of the second transverse rod 708 is perpendicular to the upper end of the clamping block 801, the first baffle 710 is located at one end of the top of the first transmission rod 701, and the second baffle 711 is located at one end of the bottom of the second transverse rod 708.

[0048] Since the first transverse rod 704, the second transverse rod 708, the first connecting block 703 and the second transmission rod 706 are rectangular, one corner of the rectangle is pulled to make the rectangle a parallelogram, thereby increasing the length of the rectangle. The rectangle can be used to push the clamping block 801 to rotate, so that the clamping block 801 contacts the component and fixes it.

[0049] The working principle and use process of the present invention:

[0050] During the assembly process of the automobile thermostat valve core parts, the automobile thermostat valve core parts are placed inside the storage platform 3, and the robot arm 4 is started by program control to grab the parts inside the storage platform 3, and the cleaning component 5 is kept vertically with the storage platform 3. At this time, the bottom of the fixed rod 111 is kept vertically with the automobile thermostat valve core parts, and the cleaning component 5 is pushed downward by the robot arm 4, and the bottom of the fixed rod 111 contacts the center rod of the automobile thermostat valve core parts. The fixed rod 111 is blocked by the center rod of the automobile thermostat valve core parts and moves upward, and the center rod is located in the middle of the second fixed cylinder 101;

[0051] In the process of the fixing rod 111 moving upward, the third sealing plate 112 is driven, and the bottom of the third sealing plate 112 is separated from the top of the second fixing cylinder 101, and the top of the second fixing cylinder 101 is in an open state. In the process of the third sealing plate 112 moving upward, the first connecting block 703 is pulled upward by the sliding block 702 and the first transmission rod 701, and the first transverse rod 704 and the second transverse rod 708 are driven respectively. Since the limit block 705 is slidably engaged with the inside of the limit groove 709, the second transmission rod 706 is limited by the limit groove 709, and one end of the first transverse rod 704 moves upward. In the embodiment, under the limitation of the first baffle plate 710 and the second transmission rod 706, the other end of the first transverse rod 704 moves downward and pushes the second transmission rod 706, and the limiting block 705 slides downward inside the limiting groove 709, so that the contact block 707 at one end of the second transverse rod 708 contacts one side of the upper end of the clamping block 801, and the second transverse rod 708 continues to rotate, pushing the clamping block 801 to rotate at the hinge, and the other side of the lower end of the clamping block 801 contacts the outside of the automobile thermostat valve core component, so that the center rod of the automobile thermostat valve core component can be fixed by one side of the lower end of the clamping block 801;

[0052] After the automobile thermostat valve core parts are fixed by the clamping block 801, the cylinder 502 is started to push the transmission plate 504 downward. Since the transmission plate 504 and the fixed housing 501 are in a sealed structure, the transmission plate 504 squeezes the gas inside the fixed housing 501 during the downward movement, and the air pressure at the lower end of the fixed housing 501 gradually increases. At the same time, since the second fixed cylinder 101 is in an open state, the gas enters the second fixed cylinder 101 respectively, and the air pressure in the second fixed cylinder 101 gradually increases, so that the rubber pad 803 Expansion, secondary clamping of the automobile thermostat valve core parts, as the transmission plate 504 continues to move downward, the air pressure in the second fixed cylinder 101 continues to increase, and the rubber pad 803 is in a saturated state, at this time, the second one-way valve inside the jet hole 103 on the inner wall of the second fixed cylinder 101 is opened, and the gas is ejected through the jet hole 103 and moves downward along the second fixed cylinder 101 and the fixed rod 111. During the movement, the surface of the parts in the second fixed cylinder 101 is cleaned, thereby improving the assembly quality of the automobile thermostat valve core parts;

[0053] Then, the center rod of the automobile thermostat valve core is assembled by the mechanical arm 4. At the same time, in the process of grabbing the automobile thermostat valve core bracket, since the outer diameter of the automobile thermostat valve core bracket is large, the mechanical arm 4 is controlled by the program to keep the bottom of the second fixed cylinder 101 vertical to the automobile thermostat valve core bracket and press down. The second fixed cylinder 101 is blocked by the automobile thermostat valve core bracket and moves upward.
