Description

Technical Field

[0001] The utility model relates to the technical field related to compressor processing, in particular to a material taking mechanism for a lower shell of a refrigerator compressor. Background Art

[0002] A refrigerator compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas, serving as the heart of the refrigeration system. It draws low-temperature, low-pressure refrigerant gas from the intake pipe, compresses it through a motor-driven piston, and discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, powering the refrigeration cycle. Removing the material from the compressor lower casing is an essential step in the compressor production process.

[0003] After extensive searching, I discovered Chinese patent publication number CN220055477U, which discloses a weighing clamp with an anti-collision mechanism. The clamp includes a clamp plate, a clamp, a clamp base, a weighing sensor, upper and lower movable plates, and a clamp cylinder. The weighing sensor is mounted between the upper and lower movable plates and the clamp base. Clamp plates are mounted on both sides of the bottom of the clamp base along the X-axis, and the clamp is mounted on the inner side of the bottom of the clamp plate. The upper and lower movable plates are also mounted with an anti-collision mechanism, which includes a pressure plate, a guide shaft, a proximity switch sensor bracket, a connecting plate, and a fixed plate. When the clamp of this utility model descends to a preset height, if the pressure plate hits a compressor before reaching the descending height, the pressure plate compresses upward, driving the sensing block at the upper end of the guide shaft to pass through the proximity switch sensor. Upon sensing the signal, the proximity switch sensor instantly stops and outputs an alarm, thus achieving the protective mechanism's function.

[0004] In summary, the existing clamping mechanism for compressors or compressor casings is usually unable to clamp multiple products at one time; in addition, after clamping, the compatibility with the tooling on the assembly line must be considered and cannot be adjusted in time.

[0005] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a refrigerator compressor lower shell material taking mechanism to make it more industrially valuable. Utility Model Content

[0012] As a further improvement of the present invention, a connecting flange is installed at the top middle position of the installation base plate.

[0013] As a further improvement of the present invention, two spacing expansion and contraction sensors are evenly distributed along the front-to-back direction on the mounting base plate at one side of the front end of the spacing expansion and contraction cylinder.

[0033] Example

[0034] like Figures 1 to 4 As shown,

[0035] A refrigerator compressor lower casing retrieving mechanism includes a mounting base 2 with a connecting flange 1 mounted in the middle of the top of the mounting base 2. The connecting flange 1 can be connected to an external robotic arm, thereby enabling the mounting base 2 to move in multiple directions. A gripper unit is mounted at the bottom of the mounting base 2 and includes a fixed gripper mechanism 8 and a movable gripper mechanism 25.

[0036] 1. Adjustment of the distance between the fixed jaw mechanism 8 and the movable jaw mechanism 25:

[0037] A spacing telescopic cylinder 3 is installed on both sides of the mounting base 2 along the left and right directions. Two fixed clamping mechanisms 8 are installed in parallel at the rear end of the bottom of the mounting base 2 along the left and right directions and through the vertical plate 5. Two movable clamping mechanisms 25 are installed in parallel at the front end of the bottom of the mounting base 2 along the left and right directions and through the vertical plate 5. The driving end of the spacing telescopic cylinder 3 drives the movable clamping mechanism 25 at the front end to move in the front and rear directions through the spacing driving plate 4 and the vertical plate 5.

[0038] Two spacing expansion sensors 6 are evenly distributed along the front-to-back direction on the mounting base plate 2 at the front end of the spacing expansion cylinder 3. When the spacing expansion cylinder 3 drives the spacing drive plate 4 at the front end to move in the front-to-back direction, the two spacing expansion sensors 6 cooperate with each other to sense whether the movable jaw mechanism 25 is in the forward or backward state.

[0039] A spacing telescopic limiting plate 7 is installed at the bottom of the mounting base plate 2 on the front end side of the spacing telescopic cylinder 3. The spacing telescopic limiting plate 7 is used to limit the vertical plate 5 on the movable clamping jaw mechanism 25 in the front end direction.

[0040] In addition, the vertical plate 5 on the movable clamping jaw mechanism 25 is also installed on the bottom of the mounting base plate 2 through a guide rail assembly distributed along the front-to-back direction.

[0041] 2. Detection rod assembly 9:

[0042] A detection rod assembly 9 is arranged between the fixed clamping mechanism 8 and the movable clamping mechanism 25. The detection rod assembly 9 includes a detection lifting cylinder 18 and a detection translation cylinder 22. The detection lifting cylinder 18 is installed on the bottom of the mounting base 2 through the detection lifting cylinder mounting seat 17. The driving end of the bottom of the detection lifting cylinder mounting seat 17 drives the detection lifting frame 19 below to move in the vertical direction. A detection rod fixed mounting frame 20 is installed on the left side of the bottom of the detection lifting frame 19. Detection rods 21 are installed on both sides of the front and back directions of the bottom of the detection rod fixed mounting frame 20. A detection translation cylinder 22 is installed on the detection lifting frame 19 on the right side of the detection lifting cylinder 18. The driving end of the detection translation cylinder 22 drives the detection rod movable mounting frame 24 on the right side to move in the left and right directions through the detection translation frame 23. Detection rods 21 are installed on both sides of the front and back directions of the bottom of the detection rod movable mounting frame 24, and the detection rods 21 are distributed along the vertical direction.

[0043] At least one detection sensor 10 is installed along the vertical direction on the vertical plate 5. The function of the detection sensor 10 is similar to that of the above-mentioned spacing expansion and contraction sensor 6. The number of the detection sensors 10 can be two and they are distributed along the vertical direction. They are adapted to the detection lifting frame 19 at the rear end, thereby sensing whether the detection rod 21 is in an ascending state or a descending state.

[0044] 3. Structural composition of the fixed clamping mechanism 8 or the movable clamping mechanism 25:

[0045] The fixed clamping mechanism 8 or the movable clamping mechanism 25 includes a clamping parallel cylinder mounting base 11 installed at the bottom of the vertical plate 5, a clamping parallel cylinder 12 is installed at the bottom of the clamping parallel cylinder mounting base 11, clamping jaws 13 are installed on the front and rear sides of the bottom of the clamping parallel cylinder 12, and a rubber pad is installed on the outside of the clamping jaw 13.

[0046] An imaging device 14 is also mounted on the vertical plate 5 , and a light source 15 coaxial with the imaging device 14 is mounted directly below the imaging device 14 .

[0047] Limit rods 16 distributed along the vertical direction are installed on both sides of the left and right sides of the bottom of the clamp parallel cylinder mounting base 11. The limit rods 16 can limit the descent of the entire structure to avoid excessive descent and cause certain damage to the clamp body.

[0048] Brief description of the working process of this utility model:

[0049] 1. The robotic arm adjacent to the connecting flange 1 drives the retrieving mechanism to move downward, and at this time, the four sets of grippers with parallel cylinders 12 retract inward;

[0050] 2. The retrieving mechanism moves downward according to the set program. When the detection rod 21 touches the shell, the detection sensor 10 lights up and the robotic arm stops moving downward.

[0051] 3. The parallel cylinder 12 with the clamping jaws opens outward and fits tightly against the inner wall of the compressor lower shell. After the robotic arm moves up to the specified height, since the distance between the compressor lower shell on the logistics vehicle and the assembly line tooling is not equal, it is necessary to adjust the distance through the distance telescopic cylinder 3 above the mechanism before sending the compressor lower shell to the specified assembly line tooling.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implying the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0053] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
