Technical Field

[0001] This invention relates to the field of automated assembly tooling technology, specifically, to an automated tooling for loading the main components of a sprayer into an adapter. Background Technology

[0002] Currently, manual sprayers are widely used, and how to mass-produce them has become a key issue. In order to install the main components of the sprayer into the adapter, most of them adopt semi-automatic assembly mechanisms, such as the Chinese invention patent application with application number CN2022111428794.

[0003] However, this type of mechanism has some drawbacks: low production efficiency, redundant and complex structure, poor stability, high defect rate, and is not conducive to mass production. Summary of the Invention

[0004] The purpose of this invention is to provide an automated tooling and method for loading the main components of a sprayer into an adapter, which can load the main components of several sprayers into the adapter at one time, which is beneficial for mass production.

[0005] The object of this invention is achieved as follows: an automated tooling for loading the main body assembly of a sprayer into an adapter, which is used to assemble adapters and main body assemblies of several sprayers into one unit, comprising:

[0006] An adapter positioning mechanism has an adapter positioning plate, the side of which has several horizontally arranged and spaced adapter slots. During assembly, the adapter is inserted into the adapter slots one by one along the side and fits into the adapter slots.

[0007] The first lifting frame is slidably connected to the machine frame and is located directly above the assembly station. It is equipped with a first upper cylinder. The cylinder barrel of the first upper cylinder is fixedly connected to the machine frame, and its piston rod is downward and connected to the first lifting frame.

[0008] The main component pressing mechanism includes a second lifting frame and a second upper cylinder. The cylinder of the second upper cylinder is fixedly connected to the side wall of the first lifting frame. The second lifting frame is slidably connected to the side wall of the first lifting frame and connected to the piston rod of the second upper cylinder. The lower end of the second lifting frame is used to press the main component downward during assembly.

[0009] A support plate that is movable and located below the main component pressing mechanism is provided with a number of support grooves that match the main components and support the main components.

[0010] A large jig assembly supporting the adapter.

[0011] Furthermore, the lower end of the second lifting frame is provided with several downward-facing upper contour grooves that fit into the main body components one by one during assembly.

[0012] Furthermore, the first lifting frame is equipped with a plurality of demolding cylinders arranged horizontally along the distribution direction of the adapter. The piston rods of the demolding cylinders are set downward, and each demolding cylinder faces downward directly towards the adapter groove. The adapter groove is U-shaped in the overhead view. During assembly, the adapter groove matches the curved surface of the adapter's side wall and supports the adapter's side wall. When assembly is completed and demolding is required, the piston rods of the demolding cylinders press downward against the plastic assembly containing the main body component to drive the plastic assembly to detach downward from the tooling.

[0013] Furthermore, the adapter positioning mechanism includes a pressing cylinder, an adapter pressure plate, and a cylinder bracket. The cylinder bracket is fixedly connected to the upper surface of the adapter positioning plate. The cylinder barrel of the pressing cylinder is fixedly connected to the cylinder bracket, and its piston rod faces downward. The adapter pressure plate is connected to the piston rod of the pressing cylinder and is movably engaged with the cylinder bracket. During assembly, driven by the pressing cylinder, the adapter pressure plate is pressed downward against the upper side of the adapter.

[0014] Also includes:

[0015] The lower lifting main frame is movably and vertically positioned below the assembly station, and the support plate is fixedly connected to the upper side of the lower lifting main frame.

[0016] The first lower lifting cylinder has its cylinder barrel fixedly connected to the frame, and its piston rod supports upward and connects to the lower lifting main frame.

[0017] A roller abutment platform is slidably connected to the lower lifting main frame.

[0018] The second lower lifting cylinder has its cylinder barrel and piston rod connected to the lower lifting main frame and the roller abutment platform, respectively, and the piston rod of the second lower lifting cylinder supports the roller abutment platform upward.

[0019] The movable lever mechanism includes a lever fulcrum seat, a swing pivot, a lever rear axle, and several inclined levers. The number of levers is equal to the number of adapters, and each lever corresponds to an adapter. The lever fulcrum seat is fixedly connected to a support plate. All levers are rotatably connected to the lever fulcrum seat via a swing pivot. The lever rear axle is fixedly threaded through all levers, and both ends of the rear axle are rotatably connected to abutment wheels. The roller abutment platform supports two abutment wheels.

[0020] A cam plate for fixed connection frame, the cam plate having a vertical edge that rolls in contact with the abutment wheel, and a protrusion protruding along the rotation direction of the lever at the upper part of the vertical edge, and an inclined transition surface between the protrusion and the vertical edge of the cam plate;

[0021] The lever has an abutment rod at its upper end. During assembly, the abutment rod supports the inner plastic rod inside the adapter, and the abutment wheel abuts against the protrusion.

[0022] As another aspect of this patent, an assembly method is proposed based on the above-mentioned tooling, which includes at least the following steps:

[0023] S1. Deliver the large jig assembly containing several adapters to the assembly station;

[0024] S2. The adapter is positioned by the adapter positioning mechanism to limit the adapter, so that the adapter is inserted into the adapter slot and matches the adapter slot.

[0025] S3. The first lower lifting cylinder pushes the lower lifting main frame upward to the assembly station, so that the main component in the support groove of the support plate is in the assembly station. The second lower lifting cylinder pushes the roller against the platform upward. The roller against the platform touches the abutting wheel upward. The abutting wheel rolls upward to the protrusion, and the lever rotates upward accordingly. The abutting rod at the upper end of the lever supports the two inner plastic rods in the adapter.

[0026] S4. The first upper cylinder pushes the first lifting frame to slide down to the assembly station and move down to meet the main body component. At the same time, the second upper cylinder pushes the second lifting frame down, so that the upper contour groove presses down to meet the main body component, thereby pressing the main body component into the adapter.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. It can load the main components of several sprayers into the adapter at one time, which is beneficial for mass production;

[0029] 2. First, the large jig assembly containing the adapter arrives at the assembly station. Then, the adapter positioning plate is moved to restrict the adapter's degree of freedom. Next, the first and second lower lifting cylinders push upwards in sequence, causing the movable lever mechanism to produce corresponding actions. The lever's contact rod supports the two inner plastic rods (elastic parts) of the adapter. Finally, the upper lifting mechanism is used to press the main body component into the adapter.

[0042] The following is in conjunction with the appendix Figure 1-12 The present invention will be further illustrated by specific embodiments.

[0043] like Figure 1 As shown, an automated tooling for loading the main body assembly of a sprayer into an adapter is used to assemble adapters 6 and main body assemblies 15 of several sprayers into one unit, comprising:

[0044] The adapter positioning mechanism 3 includes an adapter positioning plate 2. The side of the adapter positioning plate 2 has several horizontally arranged, spaced adapter grooves 2a. During assembly, the adapter 6 is inserted into each adapter groove 2a along the side and mates with it (e.g., ...). Figure 12 (as shown);

[0045] First lifting frame 8, such as Figure 2 As shown, the first lifting frame 8 is slidably connected to the frame and is located directly above the assembly station. It is equipped with a first upper cylinder 7. The cylinder barrel of the first upper cylinder 7 is fixedly connected to the frame, and its piston rod is downward and connected to the first lifting frame 8. The lower end of the first lifting frame 8 contacts the adapter 6 downward during assembly.

[0046] Main component pressing mechanism 11, such as Figure 1As shown, it includes a second lifting frame 13 and a second upper cylinder 12. The cylinder of the second upper cylinder 12 is fixedly connected to the side wall of the first lifting frame 8. The second lifting frame 13 is slidably connected to the side wall of the first lifting frame 8 and connected to the piston rod of the second upper cylinder 12. The lower end of the second lifting frame 13 is used to press down against the main body component 15 during assembly.

[0047] The support plate 29, which is movable and located below the main component pressing mechanism 11, is as follows: Figure 7 , 10 As shown, the support plate 29 is provided with a plurality of support grooves 29a that match the main body component 15 one by one and support the main body component 15.

[0048] Support adapter 6 large panel fixture set 30 (e.g.) Figure 3 (As shown).

[0049] Among them, such as Figure 1 As shown, the lower end of the second lifting frame 13 is provided with several downward-facing upper contour grooves 14 that fit downwards to fit the main body component 15 during assembly.

[0050] like Figure 2 , 5 As shown in Figure 6, the first lifting frame 8 is equipped with several demolding cylinders 10 arranged horizontally along the distribution direction of the adapter 6. The piston rods of the demolding cylinders 10 are set downwards, and each demolding cylinder 10 faces downwards directly towards the adapter groove 2a. The adapter groove 2a is U-shaped in the overhead view. During assembly, the adapter groove 2a matches the curved surface of the side wall of the adapter 6 and supports the side wall of the adapter 6. When the assembly is completed and demolding is required, the piston rods of the demolding cylinders 10 press downwards against the assembly to ensure that the assembly can be demolded smoothly.

[0051] like Figure 2 , 3 As shown, the adapter positioning mechanism 3 includes a pressing cylinder 4, an adapter pressure plate 5, and a cylinder bracket. The cylinder bracket is fixedly connected to the upper surface of the adapter positioning plate 2. The cylinder barrel of the pressing cylinder 4 is fixedly connected to the cylinder bracket, and its piston rod faces downward. The adapter pressure plate 5 is connected to the piston rod of the pressing cylinder 4 and is movably engaged with the cylinder bracket. During assembly, under the drive of the pressing cylinder 4, the adapter pressure plate 5 is pressed downward against the upper side of the adapter 6.

[0052] The adapter positioning mechanism 3 mentioned above also includes a lateral cylinder 1, the cylinder barrel of the lateral cylinder 1 is fixedly connected to the frame, and its piston rod is connected to the adapter positioning plate 2. The adapter positioning plate 2 is horizontally and movably connected to the frame.

[0053] like Figure 2As shown, the lower end of the first lifting frame 8 is fixedly connected to an auxiliary positioning plate 9. The auxiliary positioning plate 9 has several downward protruding protrusions, and the adapter pressure plate 5 has several U-shaped positioning grooves. During assembly, the protrusions of the auxiliary positioning plate 9 pass through the U-shaped positioning grooves of the adapter pressure plate 5 and abut against the adapter 6.

[0054] like Figure 4 , 7 As shown in Figure 11, the tooling also includes:

[0055] The lower lifting main frame 17 is movably positioned below the assembly station, and the support plate 29 is fixedly connected to the upper side of the lower lifting main frame 17.

[0056] The first lower lifting cylinder 16 has its cylinder barrel fixedly connected to the frame, and its piston rod supports upward and connects to the lower lifting main frame 17.

[0057] Roller abutment platform 19, roller abutment platform 19 is connected to lower lifting main frame 17 by lifting and sliding;

[0058] The second lower lifting cylinder 18 has its cylinder barrel and piston rod connected to the lower lifting main frame 17 and the roller abutment platform 19, respectively, and the piston rod of the second lower lifting cylinder 18 supports the roller abutment platform 19 upward.

[0059] Active leverage mechanism, such as Figure 4 , 7 As shown, it includes a lever fulcrum seat 24, a swing pivot 23, a lever rear axle 26, and several inclined levers 21. The number of levers 21 is equal to the number of adapters 6. Each lever 21 corresponds to an adapter 6. The lever fulcrum seat 24 is fixedly connected to the support plate 29. All levers 21 are rotatably connected to the lever fulcrum seat 24 via a swing pivot 23. The lever rear axle 26 is fixedly threaded through all levers 21. Both ends of the rear axle 26 are rotatably connected to abutment wheels 20. The roller abutment platform 19 supports two abutment wheels 20.

[0060] The cam plate 28 of the fixed connection frame, such as Figure 7 As shown, the cam plate 28 has a vertical edge that rolls in contact with the abutment wheel 20, and the upper part of its vertical edge is provided with a protrusion 28a that protrudes along the rotation direction of the lever 21. An inclined transition surface is provided between the protrusion 28a and the vertical edge of the cam plate 28.

[0061] Among them, combined Figure 7-9 As shown, the lever 21 has an abutment rod 22 at its upper end. During assembly, the abutment rod 22 supports the inner plastic rod 6a inside the adapter 6, and the abutment wheel 20 abuts against the protrusion 28a.

[0062] like Figure 4As shown, the lever fulcrum seat 24 is rotatably connected to a number of contact rollers 25, and the contact rollers 25 correspond one-to-one with the lever 21 and roll to contact the upper side of the lever 21.

[0063] In order to facilitate the downward rotation and reset of the lever 21, the rear shaft 26 of the lever is equipped with several reset springs 27, which are used to elastically connect the rear shaft 26 of the lever and the lower lifting main frame 17.

[0064] The assembly method performed using the above-mentioned tooling includes at least the following steps:

[0065] S1. Deliver the large jig assembly 30 containing several adapters 6 to the assembly station;

[0066] S2. The adapter 6 is positioned by the adapter positioning mechanism 3 to limit the adapter 6, so that the adapter 6 is inserted into the adapter slot 2a one by one and matches the adapter slot 2a.

[0067] S3. The first lower lifting cylinder 16 pushes the lower lifting main frame 17 upward to the assembly station, so that the main component 15 in the support groove 29a of the support plate 29 is in the assembly station.

[0068] The second lifting cylinder 18 pushes the roller against the platform 19 upward, the roller against the platform 19 touches the abutment wheel 20 upward, the abutment wheel 20 rolls upward to the protrusion 28a, the lever 21 rotates upward accordingly, and the abutment rod 22 at the upper end of the lever 21 supports the two inner plastic rods 6a (plastic springs) inside the adapter 6. The purpose is to drive the two inner plastic rods 6a to bend backward to prevent the subsequent main body component 15 from causing positional interference during the pressing into the adapter 6.

[0069] S4. The first upper cylinder 7 pushes the first lifting frame 8 to slide down to the assembly station and move down to meet the main body component 15. At the same time, the second upper cylinder 12 drives the second lifting frame 13 to press down, so that the upper contour groove 14 presses down to meet the main body component 15, so as to press the main body component 15 into the adapter 6.

[0070] After the main body component 15 is pressed into the adapter 6, several plastic assembly components (including the main body component 15) are formed. In order to facilitate the removal of the several plastic assembly components (including the main body component 15) from the tooling, the following steps are included:

[0071] First, release the lower movable lever mechanism, so that the abutment rod 22 of lever 21 releases the inner plastic rod 6a of adapter 6;

[0072] Secondly (this step can be performed simultaneously with the above steps), the second lifting frame 13 rises under the drive of the second upper cylinder 12 to release the main body assembly 15.

[0073] Third, the demolding cylinder 10 is used to push the plastic assembly component (including the main body component 15) downward to drive the plastic assembly component (including the main body component 15) to demold.

[0074] Fourth, the first upper cylinder 7 is used to drive the first lifting frame 8 to rise and reset.

[0075] It is worth mentioning that the wrench (the mechanism that drives the sprayer to spray) is part of the main component 15. During assembly, the inner plastic rod 6a needs to be opened by the abutment rod 22 of the lever 21 to facilitate the pressing process between the main component 15 and the adapter 6. After the inner plastic rod 6a of the adapter 6 is released, the inner plastic rod 6a elastically returns to its original position and locks the wrench of the main component 15, so that the wrench can use the inner plastic rod 6a of the adapter 6 as an elastic support base.

[0076] The problem solved by this embodiment is that it solves the problems of complexity, poor stability and low reliability of the existing semi-automatic assembly mechanism, and the above problems can be perfectly solved by using the clever assembly structure of cam plate 28 and movable lever mechanism (with lever 21 and abutment wheel 20).

[0077] The assembly steps described above are as follows: First, the large jig assembly 30 containing the adapter 6 arrives at the assembly station. Then, the adapter positioning plate 2 is moved to restrict the degree of freedom of the adapter 6. Next, the first lower lifting cylinder 16 and the second lower lifting cylinder 18 push upward in sequence, causing the movable lever mechanism to produce corresponding actions. The two inner plastic rods 6a (elastic parts) of the adapter 6 are supported by the abutment rod 22 of the lever 21. Finally, the main body assembly 15 is pressed into the adapter 6 by the lifting mechanism above.

[0078] The above are preferred embodiments of the present invention. Those skilled in the art can make various modifications or improvements based on these embodiments. Without departing from the overall concept of the present invention, such modifications or improvements should fall within the scope of protection claimed by the present invention.
