Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, specifically relating to a device for removing blockages. Background Technology

[0002] During the assembly and production of compressors, in order to prevent impurities from entering the compressor, a rubber plug (or plug) is usually installed on the suction pipe after the pumping process is completed. This part will flow with the workpiece into the subsequent process and will not be removed until the liquid separator is installed.

[0003] Currently, the process of removing blockages generally relies on manual operation, where operators manually remove them using tools such as pliers. This traditional manual method has inherent drawbacks: First, manual operation is prone to errors due to fatigue, such as missing parts or delays, directly affecting the overall pace and efficiency of the production line; second, the force applied by hand is difficult to control precisely, easily causing crushing damage to the blockage or its mounting port during the gripping and removal process. If the blockage is designed to be reusable, this affects its secondary use and poses a risk of damaging the workpiece surface; finally, reliance on manual labor means continuous labor costs and corresponding management costs, resulting in low economic benefits in the long run. Therefore, there is an urgent need for a device that can replace manual labor and achieve automated, precise operation to stably, efficiently, and non-destructively remove compressor port blockages.

In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0027] This embodiment provides a device for removing plugs, such as... Figures 1-13 As shown, the blockage removal device includes a frame 1, a rotating shaft mechanism 2, and a clamping mechanism 3. The rotating shaft mechanism 2 and the clamping mechanism 3 are both mounted on the frame 1. The rotating shaft mechanism 2 is used to adjust the angle of the compressor 4, and the clamping mechanism 3 is used to remove the blockage 41 located on the pipe opening of the compressor 4. The rotating shaft mechanism 2 and the clamping mechanism 3 are arranged sequentially according to the production line direction of the compressor 4.

[0028] Frame 1 serves as the mounting foundation and load-bearing structure for the entire device, providing a stable support platform for all moving parts. The rotating shaft mechanism 2 and the clamping mechanism 3, as two core functional modules, are both directly or fixedly mounted on frame 1 via necessary mounting brackets. The rotating shaft mechanism 2 and the clamping mechanism 3 are arranged sequentially according to the production line direction of compressor 4. This means that spatially, the rotating shaft mechanism 2 is located upstream, processing the incoming compressor 4 first, while the clamping mechanism 3 is located downstream, responsible for receiving the compressor 4 processed by the rotating shaft mechanism 2 and proceeding to the next step. The two are arranged sequentially on frame 1, forming a compact automated production line.

[0029] The core function of frame 1 is integration and support. It integrates the rotating shaft mechanism 2 and the clamping mechanism 3 into a unified whole, ensuring that they maintain a precise relative position during operation, providing a fundamental guarantee for the accuracy of all movements. The core function of rotating shaft mechanism 2 is identification and orientation adjustment. It is responsible for identifying and adjusting the angle of the compressor 4 delivered to its station. Since the compressor 4 flows in in a sideways position after the previous process, the orientation of the plug 41 on its pipe opening is random. The job of rotating shaft mechanism 2 is to adjust the plug 41 of different compressors 4 to a uniform standard orientation, creating the prerequisite for the precise operation of the subsequent clamping mechanism 3. The core function of clamping mechanism 3 is gripping and removing. It receives the compressor 4 with a uniform angle from rotating shaft mechanism 2 and performs the final plug removal action, which is the most direct link in realizing automation to replace manual operation.

[0030] The coordination between the frame 1, the rotating shaft mechanism 2, and the clamping mechanism 3 begins with the compressor 4 flowing into the rotating shaft mechanism 2. The rotating shaft mechanism 2 starts and adjusts its angle before moving it to the next station. Immediately afterwards, the compressor 4 flows into the clamping mechanism 3, which starts and performs its core functions of clamping and removing the obstruction 41. Throughout the process, the frame 1 serves as a solid base, ensuring that the two mechanisms do not shift during high-speed, repetitive movements, thus guaranteeing positioning accuracy for each operation.

[0031] The core technical problems described in the background art are solved through the cooperation of the frame 1, the rotating shaft mechanism 2, and the clamping mechanism 3. First, the device achieves fully automated operation, completely replacing manual operation, thereby fundamentally eliminating errors caused by operator fatigue and unstable production rhythm, ensuring the continuity and stability of the production process. Second, due to the use of precise mechanized control, the force and trajectory of the entire removal process are highly controllable and consistent, completely avoiding damage to the blockage part 41 or the compressor 4 pipe port caused by improper force and angle during manual operation, effectively ensuring product quality and the reusability of the blockage part. Finally, the one-time investment and long-term operation of this device significantly reduce the continuous dependence on specific operators, thereby reducing corresponding labor and management costs, resulting in better economic benefits in the long run.

[0032] In a specific embodiment, such as Figure 1 and Figure 7 As shown, the rotating shaft mechanism 2 includes a linear drive unit 21, a rotary drive unit 22, a gripper unit 23, and a sensor 24. The linear drive unit 21 is mounted on the frame 1, and its output end is connected to the input end of the rotary drive unit 22. The output end of the rotary drive unit 22 is connected to the gripper unit 23. The sensor 24 is mounted on the gripper unit 23 to identify the features of the compressor 4.

[0033] The linear drive unit 21 is fixedly mounted on the frame 1, and its output end is connected to the base or housing of the rotary drive unit 22, enabling the rotary drive unit 22 to be driven by the linear drive unit 21 and move linearly. The output end of the rotary drive unit 22, i.e., its power output shaft, is connected to the mounting base of the gripper unit 23. In this way, the gripper unit 23 can be driven by the rotary drive unit 22 to rotate, and can also follow the linear drive unit 21 to move forward and backward in a straight line. The sensor 24 is installed at a specific position on the gripper unit 23, with its sensing direction facing the area where the compressor 4 is expected to appear. This installation method ensures that the sensor 24 can detect the target area in close proximity.

[0034] The sensor 24 identifies the features of the compressor 4 entering its detection range, providing a basis for system judgment. The linear drive unit 21 provides the power for linear motion, responsible for pushing the rotary drive unit 22 and the gripper unit 23 towards the compressor 4 as a whole according to instructions, or pulling them back to their original position after completing their task. The rotary drive unit 22 provides the power for rotational motion, driving the gripper unit 23 to rotate precisely at an angle when needed. The gripper unit 23 directly contacts the compressor 4 and reliably holds it, providing a stable connection for subsequent operations.

[0035] The coordination of the linear drive unit 21, rotary drive unit 22, gripper unit 23, and sensor 24 begins with the sensor 24 identifying specific features of the compressor 4. Based on the identification result, the system determines whether adjustment is needed. If adjustment is required, the linear drive unit 21 activates, pushing the rotary drive unit 22 and gripper unit 23 towards the compressor 4, causing the gripper unit 23 to contact and hold the compressor 4. Then, the rotary drive unit 22 activates, driving the gripper unit 23 and rotating the compressor 4 to a predetermined angle. Finally, the linear drive unit 21 moves in the opposite direction, causing the gripper unit 23 to retract and release the compressor 4. This coordination achieves automatic identification and adjustment of the compressor 4's angle, ensuring that the compressor 4 enters subsequent processes with a consistent posture. This provides the necessary conditions for fully automated and precise operation, effectively avoiding the inefficiency and quality risks caused by fatigue and inaccurate force control during manual operation.

[0036] In addition, the core function of sensor 24 is to identify the features of compressor 4. It can be a non-contact photoelectric sensor. More specifically, sensor 24 is a through-beam photoelectric sensor. This sensor includes separate transmitter and receiver parts. The transmitter and receiver are mounted opposite each other on the two gripping arms of gripper unit 23. When the L-shaped support of compressor 4 enters the predetermined position of gripper unit 23, it blocks the light beam emitted from the transmitter to the receiver. The receiver detects the change in light signal, thereby generating an electrical signal indicating that "target feature has been detected." Sensor 24 can also be a diffuse reflection photoelectric sensor. Its transmitter and receiver are integrated and mounted on a single gripping arm of gripper unit 23. It determines the presence or absence of a feature by detecting the light signal reflected back from the surface of the L-shaped support of compressor 4. Sensor 24 can also be a proximity switch, such as an inductive proximity switch for detecting L-shaped supports made of metal; or a capacitive proximity switch for detecting non-metallic objects.

[0037] In a specific embodiment, such as Figures 7-9 As shown, the rotating shaft mechanism 2 further includes a gear unit 25, the output end of the rotary drive unit 22 is connected to the gear unit 25, and the gear unit 25 is connected to the gripper unit 23 in a transmission manner; the housing of the gear unit 25 and the rotary drive unit 22 is connected to the output end of the linear drive unit 21.

[0038] The power output end of the rotary drive unit 22 is connected to the gear unit 25, transmitting rotational power to the gear unit 25; the gear unit 25 is further connected to the gripper unit 23, ultimately transmitting power to the gripper unit 23; at the same time, the housing of the rotary drive unit 22 and the base of the gear unit 25 are both fixedly connected to the output end of the linear drive unit 21, which enables the linear drive unit 21 to drive the rotary drive unit 22 and the gear unit 25 as a whole to move synchronously in a linear manner.

[0039] The technical benefits of this connection method are multifaceted and significant. First, it establishes an efficient and reliable power transmission chain. The torque generated by the rotary drive unit 22, transmitted smoothly and precisely through the meshing of the gear unit 25, drives the gripper unit 23 to rotate. This provides the necessary power foundation for accurately controlling the adjustment angle of the compressor 4. Second, the design of rigidly connecting the rotary drive unit 22 and the gear unit 25 to the linear drive unit 21 allows the entire system providing rotational power to be moved as a whole. This enables the gripper unit 23 to extend forward to hold the compressor 4 when needed, or to retract backward to make room on the production line after completion—a core action for automated operation. Furthermore, this integrated design ensures that the relative positions between the rotary drive unit 22 and the gear unit 25, and between the gear unit 25 and the gripper unit 23, remain constant during linear movement. This avoids transmission errors caused by movement and ensures repeatability accuracy for each angle adjustment.

[0040] In a specific embodiment, such as Figure 9 As shown, the gear unit includes a first gear 251, a second gear 252, a connecting shaft 253, and a turntable 254. The first gear 251 and the second gear 252 mesh. The first gear 251 is connected to the output end of the rotary drive unit 22. The turntable 254 is connected to the second gear 252 through the connecting shaft 253. The gripper unit 23 is mounted on the turntable 254.

[0041] The first gear 251 is mounted on the output shaft of the rotary drive unit 22, enabling it to receive the prime mover from the rotary drive unit 22 and rotate accordingly. The second gear 252 maintains continuous meshing with the first gear 251, and its mounting position is closely adjacent to the first gear 251 to ensure smooth transmission. One end of the connecting shaft 253 is fixedly connected to the second gear 252, allowing the rotational motion of the second gear 252 to be directly transmitted to the connecting shaft 253. The other end of the connecting shaft 253 is fixedly connected to the turntable 254, thus ultimately transmitting power to the turntable 254. The gripper unit 23 is fixedly mounted on the turntable 254, allowing the rotation of the turntable 254 to be directly converted into the rotation of the gripper unit 23.

[0042] The primary function of the first gear 251 is as a primary transmission component, receiving the rotational speed and torque output from the rotary drive unit 22 and transmitting it to the meshing second gear 252. The second gear 252 alters the transmission characteristics; by meshing with the first gear 251, it can change the rotational speed or increase the torque, and output the adjusted power to the connecting shaft 253. The connecting shaft 253 acts as a bridge for power transmission, reliably transmitting the rotational motion of the second gear 252 to the turntable 254 at a certain distance, while also bearing the torque generated during transmission. The turntable 254 serves as the final output platform and mounting base, converting the rotational motion transmitted from the connecting shaft 253 into its own circumferential rotation and that of the gripper unit 23, thereby achieving angle adjustment of the compressor 4.

[0043] When the rotary drive unit 22 is started, it drives the first gear 251 to rotate. The first gear 251, through its meshing relationship with the second gear 252, drives the second gear 252 to rotate. The rotation of the second gear 252 is transmitted to the turntable 254 through the connecting shaft 253, ultimately causing the gripper unit 23 mounted on the turntable 254 to rotate. The beneficial effects of this method are mainly reflected in several aspects: First, the gear transmission achieves efficient and stable power transmission, ensuring the stability and reliability of the angle adjustment process; second, the precise transmission ratio characteristics of the gear meshing transmission enable precise control of the rotation angle of the gripper unit 23, meeting the high-precision requirements of the compressor 4 angle adjustment; and third, the structural design of the turntable 254 provides a stable mounting platform for the gripper unit 23, ensuring its rigidity and stability during rotation.

[0044] In a specific embodiment, the gripper unit 23 is configured to hold onto the L-shaped support leg 42 of the compressor 4.

[0045] The shape, size, and operation of the gripper unit 23 are specifically designed to adapt to the shape of the L-shaped support leg 42 of the compressor 4, thereby enabling reliable gripping and securing of this particular structure. More specifically, this means that the gripper unit 23 may include a latch or clamping surface that matches the contour of the L-shaped support leg 42, and when it is pushed by the linear drive unit 21 to contact the compressor 4, it can be firmly held onto the L-shaped support leg 42 by closing or embedding, providing a stable basis for subsequent angle adjustments.

[0046] The most direct effect of this embodiment is the realization of rapid, precise, and non-destructive positioning and clamping of the compressor 4. Because the shapes of the gripper unit 23 and the L-shaped support 42 are mutually compatible, each clamping action is completed in the predetermined correct position, greatly improving the repeatability and reliability of the operation. Furthermore, by utilizing the inherent L-shaped support 42 on the compressor body as the clamping point, there is no need to design additional tooling positioning structures on the compressor housing, avoiding any possible damage or indentation to the compressor body and ensuring the final quality of the product. From the perspective of compatibility and versatility, choosing the standardized L-shaped support 42 as the reference feature for clamping allows the gripper unit 23 to adapt to all compressor models with such standard supports, enhancing the application range of the equipment.

[0047] In a specific embodiment, such as Figure 12 As shown, the gripper unit 23 includes a cam-driven gripper for positioning the connection hole on the L-shaped support leg 42 of the compressor 4.

[0048] This embodiment describes a specific implementation of the gripper unit 23, the core of which lies in the use of a special gripper design controlled by a cam mechanism. This gripper is specifically configured such that, when pushed near the L-shaped support leg 42 of the compressor 4, it can expand or retract under the control of the cam, allowing the end positioning pin or chuck of the gripper to precisely insert or engage with a pre-existing connection hole on the L-shaped support leg 42. This connection hole is typically a standard hole used in compressor assembly for connecting shock-absorbing washers or other components.

[0049] This embodiment achieves higher positioning precision because positioning using holes offers greater repeatability compared to positioning based on external contours. The hole positions provide clear and wear-resistant reference features, ensuring consistent positioning of the compressor 4 during each clamping operation. This provides a more reliable foundation for subsequent angle adjustments and removal operations. Furthermore, this positioning method enhances compatibility with different compressor models. While the external shape of the L-shaped support legs 42 may vary for some compressor models, the connecting holes are often standardized. By using positioning holes rather than external shapes, the same set of gripper units 23 can adapt to a wider range of compressors, improving the equipment's versatility and application value. Simultaneously, this insertion hole positioning method provides a more flexible contact, avoiding potential squeezing or scratching of the external contours and better protecting the appearance quality of the compressor 4.

[0050] In a specific embodiment, the clamping mechanism 3 includes a multi-dimensional driving unit 31, a clamping unit 32, and an ejection unit 33. The multi-dimensional driving unit 31 is disposed on the frame 1 to provide linear motion in at least two directions. The clamping unit 32 is connected to the output end of the multi-dimensional driving unit 31 to clamp and remove the plug 41. The ejection unit 33 is disposed beside the clamping unit 32 to push the removed plug 41 off. The multi-dimensional driving unit 31 is configured to drive the clamping unit 32 to perform linear motion with constant acceleration.

[0051] The multi-dimensional drive unit 31 is fixedly mounted on the frame 1, and its output end is connected to the base of the clamping unit 32. This connection enables the multi-dimensional drive unit 31 to drive the entire clamping unit 32 to move precisely in multiple directions. The ejection unit 33 is independently located on the side of the clamping unit 32. Its installation method ensures that its operating direction maintains a specific angular relationship with the clamping surface of the clamping unit 32, usually opposite to the opening direction of the clamping unit, so as to effectively eject the plug 41 from the clamping unit 32.

[0052] The main function of the multi-dimensional drive unit 31 is to provide precise spatial positioning capabilities. It drives the clamping unit 32 to move in multiple linear directions, ensuring that the clamping unit 32 can accurately approach and align the plug 41 on the compressor 4 pipe opening. The core function of the clamping unit 32 is to perform the specific clamping and removal operations. It is responsible for firmly clamping the plug 41 after reaching the predetermined position and removing it from the compressor 4 through subsequent linear motion. The function of the ejection unit 33 is to push down any plug 41 that may still remain in the clamping unit 32 after the plug 41 has been successfully removed, ensuring that it falls smoothly into the recovery device, completing the entire cleaning process.

[0053] Once the compressor 4 is delivered to the working position, the multi-dimensional drive unit 31 first drives the clamping unit 32 to move, aligning it with the location of the blockage 41. Then, the clamping unit 32 performs a closing action, firmly clamping the blockage 41. Subsequently, the multi-dimensional drive unit 31 drives the clamping unit 32 in a linear backward motion with constant acceleration, smoothly removing the blockage 41 from the compressor 4. Finally, the ejection unit 33 pushes off any blockages that may be stuck in the clamping unit 32. This coordinated approach ensures the smoothness and reliability of the entire removal process. The constant acceleration characteristic helps achieve stable force control, avoiding damage to the blockage 41 or the compressor 4 nozzle due to sudden impact forces. It also improves the success rate and consistency of the operation, ultimately achieving efficient and non-destructive automated removal.

[0054] In addition, to achieve "constant acceleration motion", it is necessary to issue specific control commands to the drive servo motor or stepper motor of the multi-dimensional drive unit 31 through a programmable motion controller (such as a PLC).

[0055] In a specific embodiment, such as Figure 5 As shown, the clamping unit 32 includes a first toothed plate 321, a second toothed plate 322, and a toothed plate drive member 323. The first toothed plate 321 and the second toothed plate 322 are disposed opposite to each other, and the toothed plate drive member 323 is used to drive the first toothed plate 321 and / or the second toothed plate 322 to open and close. The meshing surface shape of the first toothed plate 321 and the second toothed plate 322 is set to be able to enclose the root of the plug 41.

[0056] The first toothed plate 321 and the second toothed plate 322 are mounted opposite each other on the bracket of the clamping unit 32 via guide rails or hinges, maintaining a parallel and opposing relationship with their meshing surfaces corresponding to each other. The toothed plate drive unit 323 is fixedly mounted on the base of the clamping unit 32, and its output end is connected to the first toothed plate 321 and / or the second toothed plate 322 via a linkage or cam mechanism, thereby driving the two toothed plates to perform linear movements towards or away from each other. The meshing surface contours of the first toothed plate 321 and the second toothed plate 322 are specially designed, their shapes matching the geometric features of the root of the plug 41, so that when the two toothed plates are closed, they can completely cover the root of the plug 41.

[0057] The first toothed plate 321 and the second toothed plate 322 together constitute the core actuators of the clamping function. Their function is to directly contact and firmly clamp the root area of ​​the plug 41, providing reliable clamping force for subsequent removal operations. The toothed plate drive 323 serves as a power source, providing the necessary driving force to precisely control the opening and closing movements of the two toothed plates, ensuring the timeliness and stability of the clamping action. More specifically, the toothed plate drive 323 needs to ensure that the two toothed plates can close with sufficient force to clamp the plug 41, and at the same time, it must be able to accurately open at the appropriate time to release the plug 41 or cooperate with the ejection unit 33 to complete the discharge.

[0058] When the clamping unit 32 moves to the predetermined position under the drive of the multi-dimensional drive unit 31, the toothed plate drive component 323 first drives the first toothed plate 321 and the second toothed plate 322 to close. The special meshing surface shape of the two toothed plates ensures complete envelopment and firm clamping of the root of the plug 41. Subsequently, the multi-dimensional drive unit 31 drives the entire clamping unit 32 to retreat at a constant acceleration, smoothly removing the plug 41. Finally, before the ejection unit 33 moves, the toothed plate drive component 323 drives the two toothed plates to open again. This cooperation method ensures the stability and reliability of the clamping process. The special tooth shape design makes the clamping force evenly distributed, avoiding excessive local stress that could damage the plug 41. At the same time, the complete envelopment characteristic prevents slippage or detachment during the removal process, improving the success rate and reliability of the operation.

[0059] In a specific embodiment, such as Figure 4 As shown, the ejection unit 33 includes a first cylinder 331 and a push plate 332. The output end of the first cylinder 331 is connected to the push plate 332, and the movement path of the push plate 332 is set on the opening side of the clamping unit 32.

[0060] The first cylinder 331 is fixedly mounted on the base of the frame or clamping mechanism 3 as a power source. The end of its piston rod is rigidly connected to the push plate 332 by means of threads or flanges, so that the linear reciprocating motion of the first cylinder 331 can be directly transmitted to the push plate 332. The movement path of the push plate 332 is specially designed so that its movement trajectory is aligned with the opening side of the clamping unit 32, ensuring that when the first toothed plate 321 and the second toothed plate 322 of the clamping unit 32 open, the push plate 332 can intervene in time and pass through the gap between the toothed plates.

[0061] After the clamping unit 32 completes the removal action, the first toothed plate 321 and the second toothed plate 322 open under the drive of the toothed plate drive member 323. At this time, the first cylinder 331 immediately moves to push the push plate 332 forward rapidly along a predetermined path. During the movement, the push plate 332 contacts and pushes the blockage 41 stuck between the toothed plates, causing it to disengage from the clamping area. Since the movement path of the push plate 332 corresponds to the inlet of the recycling device, the pushed-out blockage 41 naturally falls into the collection container under the action of gravity. This cooperation ensures that the cleaning process can be completed automatically after each removal operation, avoiding the need for manual intervention to remove residual blockage 41, significantly improving the continuous operation capability and overall work efficiency of the equipment, while eliminating the risk of equipment jamming or failure of the next clamping due to the retention of blockage 41.

[0062] In a specific embodiment, the multi-dimensional driving unit 31 includes three mutually perpendicular linear slide rail units to achieve the positioning of the clamping unit 32 in three-dimensional space.

[0063] The multi-dimensional drive unit 31 includes three mutually perpendicular linear slide rail units, each corresponding to the motion control of the X, Y, and Z axes in space. Through the coordinated operation of these three slide rail units, the clamping unit 32 can be precisely positioned in three-dimensional space. More specifically, one slide rail unit is responsible for a large-stroke movement along the axial direction of the compressor 4 nozzle to achieve the plug removal action, while the other two slide rail units are used for fine-tuning in the horizontal and vertical directions, respectively, so that the clamping unit 32 can accurately align with and approach the location of the plug 41. This arrangement can not only adapt to the differences in nozzle height and orientation of different models of compressor 4, but also maintain a stable linear motion trajectory during the plug removal process. Furthermore, through the control of the multi-dimensional drive unit 31, the clamping unit 32 can perform a linear plug removal action with constant acceleration, effectively avoiding damage to the rubber plug or nozzle due to excessive instantaneous force, while improving the success rate and consistency of plug removal. In addition, the three-dimensional positioning capability also makes the entire fixture mechanism 3 highly adaptable, and can cooperate with the rotating shaft mechanism 2 to complete the angle adjustment, so as to achieve stable and efficient completion of automated plug removal operation in a variable production line environment.

[0064] In a specific embodiment, such as Figure 1 As shown, the blockage removal device further includes a clamping assembly 5, which includes a second cylinder 51 and a clamping plate 52. The clamping plate 52 is connected to the output end of the second cylinder 51 and is used to fix the compressor 4 when removing the blockage 41.

[0065] The second cylinder 51 serves as the power source, and its output directly drives the clamping plate 52 to perform a vertical linear motion. When the compressor 4 is transported to the station of the clamping mechanism 3, the clamping assembly 5 begins to work. The second cylinder 51 pushes the clamping plate 52 downward and clamps the housing of the compressor 4, thereby firmly fixing it to the station during the subsequent removal of the plug 41. This fixing action is crucial because the clamping mechanism 3 applies a considerable linear pulling force to the plug 41 when performing the plug removal action. If the compressor 4 itself moves or vibrates, it may not only lead to plug removal failure but also pose a risk of damaging the surface of the compressor 4 or its internal parts. More specifically, the design of the clamping plate 52 allows it to stably contact the shape of the compressor 4, evenly distribute pressure, and avoid excessive local stress. With the assistance of the clamping assembly 5, the clamping unit 32 of the clamping mechanism 3 can more accurately align the plug 41 and perform a linear plug removal action with constant acceleration, ensuring a high success rate and consistency of operation. In addition, this stable compression method also enhances the adaptability of the entire device to different models of compressors 4, making the automated process more reliable and efficient.

[0066] In a specific embodiment, the rotating shaft mechanism 2 is configured to adjust the angle of the compressor 4 so that the plugs 41 on the pipe openings of different models of compressor 4 maintain the same orientation when entering the work station of the clamping mechanism 3.

[0067] The core function of the rotating shaft mechanism 2 is to precisely adjust the angle of the compressor 4. It uses a linear drive unit 21 to move the gripper unit 23 closer to the compressor 4, and a sensor 24 on the gripper unit 23 identifies the characteristic positions of features such as the L-shaped support leg 42 on the compressor 4. Once identification is complete, the rotary drive unit 22 drives the gripper unit 23 to rotate, thereby causing the clamped compressor 4 to rotate around its axis to a preset standard angle. This process ensures that regardless of the initial posture of the compressor 4 when it enters the workstation, the plug 41 on its nozzle can ultimately be adjusted to a uniform, ideal position facing the clamping mechanism 3. More specifically, this pre-defined angle standardization lays a solid foundation for subsequent automated plug removal operations. It allows the clamping unit 32 of the clamping mechanism 3 to directly and accurately align the plug 41 without complex spatial searches, greatly improving the reliability and efficiency of the operation. Furthermore, this design significantly enhances the adaptability of the entire blockage removal device to different models of compressor 4, because as long as it has identifiable features such as L-shaped support legs 42, the rotating shaft mechanism 2 can complete the angle correction, thereby ensuring the stability of the production line cycle and the smooth operation of the entire automated process.

[0068] In a specific embodiment, the plug 41 is a rubber plug on the suction pipe of the compressor 4.

[0069] The plug 41 specifically refers to the rubber plug installed on the intake port during the assembly of the compressor 4 to prevent impurities from entering. Since this plug needs to be removed and may be reused, its material is typically elastic and fits tightly to the port, requiring the automated removal operation to balance force and precision control. More specifically, the clamping unit 32 of the clamping mechanism 3 has a toothed design on its first toothed plate 321 and second toothed plate 322 that perfectly encloses the root of the rubber plug. This is a special optimization specifically for this soft, fragile rubber plug structure, ensuring that the plug body is not squeezed or cut during engagement. Furthermore, the rotating shaft mechanism 2 pre-adjusts the compressor 4 to a uniform angle to ensure that the rubber plug can meet the clamping mechanism 3 in the best possible position, thereby improving the success rate of gripping. The fact that plug 41 is clearly identified as a rubber plug highlights that the core problem solved by this device is to achieve automated and non-destructive removal of this specific vulnerable component. Its effect is not only to replace manual labor and improve efficiency, but also to protect the integrity of the rubber plug through precise mechanical design, ensuring its reusability. At the same time, it avoids potential damage to the precision nozzle of compressor 4 due to improper operation, and ultimately achieves high-quality and high-reliability automated production.

[0070] The entire automatic plug removal device begins with the compressor 4, lying on its side, flowing into the station of the rotating shaft mechanism 2 along the production line. At this point, the sensor 24 on the gripper unit 23 first identifies the angle of the L-shaped support leg 42 on the compressor 4. If the angle of the compressor 4 does not meet the preset standard, the linear drive unit 21 activates, pushing the entire rotary drive unit 22 and the gear unit 25 mounted at its output end forward, allowing the gripper unit 23 to reliably hold the L-shaped support leg 42 of the compressor 4. Immediately afterwards, the rotary drive unit 22 starts, transmitting the rotational motion to the turntable 254 via the meshing of the first gear 251 and the second gear 252 through the connecting shaft 253, thereby causing the gripped compressor 4 to rotate until the plug 41 on its suction pipe is adjusted to a uniform, predetermined position. After adjustment, the linear drive unit 21 retracts, the gripper unit 23 releases the L-shaped support leg 42, and the compressor 4 is released to the station of the clamping mechanism 3.

[0071] When the compressor 4 reaches the clamping mechanism 3, the clamping assembly 5 actuates, and the second cylinder 51 drives the clamping plate 52 to press down, fixing the compressor 4 housing on the workstation and providing a foundation for the subsequent plug removal operation. Subsequently, the multi-dimensional drive unit 31 begins operation, its three linear slide rail units moving in tandem to drive the clamping unit 32 to precisely position itself in three-dimensional space, allowing the first toothed plate 321 and the second toothed plate 322 to accurately move to both sides of the rubber plug in the suction pipe. The toothed plate drive component 323 actuates, driving the first toothed plate 321 and the second toothed plate 322 to close, its unique toothed design achieving a full-envelope engagement at the root of the rubber plug. Immediately afterwards, the main slide rail in the multi-dimensional drive unit 31 drives the clamping unit 32 to perform a linear backward movement with a constant acceleration, smoothly and completely pulling the plug 41 out of the suction pipe.

[0072] After the plug removal action is completed, the toothed plate drive 323 controls the first toothed plate 321 and the second toothed plate 322 to open. At the same time, the first cylinder 331 of the ejection unit 33 quickly actuates, pushing the push plate 332 to push the stuck rubber plug laterally, causing it to fall into the designated recycling device. Finally, the second cylinder 51 of the clamping assembly 5 lifts the clamping plate 52, releasing the compressor 4 from its fixation. The compressor 4, having completed all operations, is transported to the next process, and the entire device is reset to await the next work cycle.

[0073] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.
