Description

Technical Field

[0001] This utility model relates to the field of compressor manufacturing technology, and in particular to a multi-functional clamping device and compressor production line. Background Technology

[0002] In the production process of air conditioner compressors, a layer of foam material is usually fixed underneath to protect the compressor from vibration and impact damage during transportation. However, currently, the clamping of the compressor foam mainly relies on manual operation. This traditional operation mode has exposed many drawbacks: on the one hand, from the perspective of production efficiency, manual clamping of foam is time-consuming and slow, which is difficult to meet the high efficiency requirements of modern large-scale production, becoming a bottleneck restricting production progress; on the other hand, in terms of safety risks, manual clamping of compressor foam requires workers to enter the robot's operating area, which is a high-risk area. The operation of the robot poses extremely high safety hazards, and even a slight mistake could lead to injury to the operator, seriously threatening the worker's life. Although some manufacturers are trying to use machines to replace manual clamping of compressor foam, due to the completely different structures of compressors and foam, different clamps need to be set up on the production line to clamp the compressor and foam separately. This increases the floor space and construction cost of the compressor production line, which is not conducive to improving the company's market competitiveness.

[0003] Therefore, it is necessary to improve the existing foam clamping method of the compressor in order to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a multi-functional clamping device that can clamp the compressor and packaging foam separately through different clamping structures, thereby saving the cost of setting up a compressor production line; while using the clamping structure to clamp the foam can save labor costs and improve the production efficiency of the compressor.

[0005] A multi-functional gripping device, comprising:

[0006] A bracket, wherein a first clamping structure and a second clamping structure are provided on the bracket, and the second clamping structure is located on one side of the first clamping structure;

[0007] The second clamping structure includes two cooperating second grippers, which are slidably disposed on the bracket.

[0008] In one application, the first gripping structure of the clamping device is used to grip the compressor, and the second gripping structure is used to grip the packaging foam. This multi-functional clamping device can be installed at the end effector of a 6-axis robot. The robot, through programming control, can automatically grip and place the compressor and packaging foam. When the compressor needs to be gripped, the robot controls the first gripping structure to grip the compressor and place it in the designated position. When the packaging foam needs to be gripped, the robot controls the second gripping structure to grip the packaging foam and place it below the compressor. This device can simultaneously grip both the compressor and the packaging foam without requiring a separate dedicated foam gripping device, thus saving the cost of setting up a compressor production line. Using the gripping structure to grip the foam eliminates the need for manual entry into hazardous areas, saving labor costs and improving the safety of the production process.

[0009] In a preferred embodiment of this invention, one side of the bracket is provided with two opposing mounting seats, each of which is provided with a mounting groove.

[0010] Each of the mounting bases is provided with a sliding frame, and a guide rail is provided on one side of the sliding frame. The guide rail is slidably engaged with the mounting groove; the second gripper is provided on the sliding frame.

[0011] In this embodiment, the guide rail slides into the mounting groove. This design allows the sliding frame to slide along the direction of the mounting groove on the mounting base, thereby enabling position adjustment of the gripping structure. The second gripper is mounted on the sliding frame, and by moving the sliding frame, the second gripper can flexibly adjust its position to accommodate the gripping of packaging foam of different sizes and positions.

[0012] In this embodiment, the position of the second gripper can be adjusted manually by adjusting the position of the sliding frame. After the second position is adjusted to the correct position, the sliding frame needs to be locked using a locking structure.

[0013] In a preferred embodiment of this invention, the bracket is provided with a first driving structure, the first driving structure is provided with two output ends, and the two output ends are respectively connected to one of the sliding frames;

[0014] The first drive structure drives the two sliding brackets to slide on the mounting base.

[0015] In a preferred embodiment of this invention, a distance sensor is provided on the bracket, and the distance sensor is located between the two sliding frames.

[0016] In this embodiment, the position adjustment of the sliding frame is achieved through a first driving structure, which is a dual-output motor. The two outputs of the motor are connected to the two sliding frames via transmission mechanisms (such as gears or belts). The first driving structure can simultaneously or separately drive the two sliding frames to slide on the mounting base, thereby adjusting the position of the second gripper. A distance sensor is used to detect the distance between the sliding frames in real time, or the distance between the sliding frames and the target object (such as a compressor or packaging foam), providing precise control signals to the first driving structure. The first driving structure can precisely control the movement of the sliding frames. Combined with the real-time feedback from the distance sensor, the second gripper can accurately align with the target object (packaging foam), greatly improving the gripping accuracy. The use of a distance sensor makes the gripping operation more intelligent, automatically adjusting the position of the gripper and reducing manual intervention and errors.

[0017] In a preferred embodiment of this invention, a limiting block is provided on the bracket, and a baffle is provided on the sliding frame, with the limiting block corresponding to the baffle.

[0018] The cooperation between the limit block and the baffle is used to restrict the sliding position of the sliding frame, thereby preventing the sliding frame from falling off the support.

[0019] In a preferred embodiment of this invention, one side of the second gripper is hinged to the sliding frame, and the sliding frame is further provided with a second driving structure, the output end of which is hinged to the second gripper. The second driving structure can be a cylinder, which drives the second gripper to rotate on the support, thereby controlling the opening and closing of the second gripper.

[0020] In a preferred embodiment of this utility model, the second gripper includes a base and a claw hook. A connecting rod is provided on the base, and the connecting rod is hinged to the sliding frame. The claw hook is located on the side of the base away from the connecting rod.

[0021] The claw hooks are L-shaped and multiple claw hooks are arranged in parallel on the base.

[0022] The L-shaped hook design of the second gripper allows for better grasping and securing of objects, especially softer materials such as packaging foam. The L-shaped hook provides better support and clamping force, preventing objects from slipping. Furthermore, the precise control of the second drive structure makes the opening and closing of the hook smoother, further improving gripping stability.

[0023] In a preferred embodiment of this utility model, the bracket is further provided with a connecting seat, and the connecting seat is provided with a connecting flange;

[0024] The axis of the first clamping structure coincides with the axis of the connecting flange.

[0025] The connecting seat is equipped with a connecting flange, the axis of which coincides with the axis of the first gripping structure. This design ensures the symmetry and operational accuracy of the gripping structure when the multi-functional gripping device is installed at the end of the robotic arm.

[0026] In a preferred embodiment of this invention, the first clamping structure includes a driving cylinder and a plurality of first grippers. The driving cylinder is fixed on the connecting seat, the first grippers are disposed at the output end of the driving cylinder, and the plurality of first grippers are arranged in a ring on the driving cylinder.

[0027] Multiple first grippers are arranged in a ring around the output end of the drive cylinder. This design allows the first grippers to be evenly distributed, better gripping and securing the compressor. This application can use three first grippers to stably hold the compressor, ensuring gripping stability.

[0028] The second objective of this utility model is a compressor production line, including a conveyor line and a robotic arm, wherein the robotic arm is equipped with the multi-functional gripping device described above.

[0029] This production line uses a multi-functional clamping device to simultaneously clamp and place the compressor and packaging foam, reducing equipment changeover time and operating steps; it also reduces manual intervention in the production process and greatly improves the production efficiency of the compressor production line.

[0030] The beneficial effects of this utility model are as follows:

[0031] This utility model provides a multi-functional clamping device, which includes a support frame. A first clamping structure and a second clamping structure are mounted on the support frame, with the second clamping structure located to one side of the first clamping structure. The second clamping structure includes two cooperating first grippers slidably mounted on the support frame. During use, the device first clamps the compressor using the first clamping structure, places the compressor in a designated position, and then adjusts the position of the clamping device. The second clamping structure then clamps the compressor's packaging foam, placing the foam onto the compressor to protect it. The entire clamping process can be driven by a robotic arm, saving on the setup cost of the compressor production line. Furthermore, using the clamping structure to clamp the foam eliminates the need for manual entry into hazardous areas, saving labor costs and improving production safety. In addition, automated clamping and placement of the compressor and packaging foam reduces manual operation time and errors, improving the overall production efficiency of the compressor production line.

[0032] This application also provides a compressor production line that includes a multi-functional gripping device. The production line reduces manual intervention and greatly improves the production efficiency of the compressor production line through the automated operation of the robotic arm and the multi-functional gripping device. By using the multi-functional gripping device, there is no need to purchase and install special foam gripping equipment, which reduces the construction cost of the production line and thus reduces the manufacturing cost of the compressor.

[0041] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0042] In the production process of air conditioner compressors, a layer of foam material is usually fixed underneath them to protect them from vibration and impact damage during transportation. However, currently, the clamping of the compressor foam mainly relies on manual operation. This traditional operation mode is inefficient and poses safety risks. Although some manufacturers are trying to use machines to replace manual clamping of the compressor foam, the completely different structures of the compressor and the foam mean that different clamps need to be set up on the production line to clamp the compressor and the foam separately. This increases the floor space and construction cost of the compressor production line, which is detrimental to improving the company's market competitiveness.

[0043] Based on this, this application provides a multifunctional gripping device.

[0044] Example 1

[0045] like Figures 1-6 As shown, this embodiment provides a multi-functional gripping device, including:

[0046] The bracket 1 is provided with a first clamping structure 3 and a second clamping structure, wherein the second clamping structure is located on one side of the first clamping structure 3;

[0047] The second clamping structure includes two cooperating second jaws 5, which are slidably disposed on the bracket 1.

[0048] Specifically, the bracket 1 of this application is made of high-strength steel to ensure the stability and durability of the device. The layout of the second clamping structure located on one side of the first clamping structure 3 allows the device to simultaneously perform clamping operations on two different objects (compressor and packaging foam).

[0049] In one specific embodiment, the support 1 is further provided with a connecting seat 2, and the connecting seat 2 is provided with a connecting flange 21; the axis of the connecting flange 21 coincides with the axis of the first gripping structure 3. The design of the connecting seat 2 and the connecting flange 21 ensures the precise connection between the multi-functional gripping device and the end effector of the robotic arm, improving the stability and operational accuracy of the entire device. The coincidence of the axis of the connecting flange 21 with the axis of the first gripping structure 3 allows the gripping device to maintain symmetry and consistency under the drive of the robotic arm, reducing operational errors caused by unstable connection.

[0050] The first gripping structure 3 of this gripping device is used to grip the compressor, and the second gripping structure is used to grip the packaging foam. In addition to being used to grip the compressor and the packaging foam separately, this multi-functional gripping device can also be used to grip other items.

[0051] More specifically, the first clamping structure 3 includes a drive cylinder 31 and a plurality of first grippers 32. The drive cylinder 31 is fixed on the connecting seat 2, the first grippers 32 are disposed at the output end of the drive cylinder 31, and the plurality of first grippers 32 are arranged in a ring on the drive cylinder.

[0052] Multiple first grippers 32 are arranged in a ring around the output end of the drive cylinder 31. This design allows the first grippers 32 to be evenly distributed, better gripping and securing the compressor. This application can provide three first grippers 32, using these three grippers to stably hold the compressor, ensuring gripping stability.

[0053] Specifically, this multi-functional gripping device can be installed at the end effector of a 6-axis robot. The robot, through programmable control, can automatically grip and place the compressor and packaging foam. When the compressor needs to be gripped, the robot, through programmable control, drives the cylinder 31 to actuate, causing multiple first grippers 32 to open and grip the compressor. Because the first grippers 32 are arranged in a ring, the gripping force is evenly distributed, ensuring gripping stability. After gripping, the robot places the compressor in the designated position. When the packaging foam needs to be gripped, the robot controls the second gripping structure to actuate. The second gripper 5 is slidably mounted on the support 1, allowing for flexible position adjustment to accommodate packaging foam of different sizes. After gripping, the robot places the packaging foam in the designated position below or above the compressor. The robot completes the assembly of the gripped compressor and packaging foam, and then a conveyor line transports the assembled product to the next process.

[0054] This multi-functional clamping device can simultaneously grip both the compressor and packaging foam, eliminating the need for a separate foam gripping system and thus saving on the cost of setting up a compressor production line. By utilizing the clamping structure to grip the foam, manual operation in hazardous areas is eliminated, saving labor costs and improving production safety. Furthermore, the automated gripping and placement of the compressor and packaging foam reduces manual operation time and errors, thereby increasing the overall production efficiency of the compressor production line.

[0055] Example 2

[0056] This embodiment is an improvement on embodiment 1.

[0057] like Figures 1-6 As shown, in this embodiment, two opposing mounting seats 11 are provided on one side of the bracket 1, and each mounting seat 11 is provided with a mounting groove.

[0058] Each of the mounting bases 11 is provided with a sliding frame 4, and a guide rail 41 is provided on one side of the sliding frame 4. The guide rail 41 is slidably engaged with the mounting groove; the second gripper 5 is provided on the sliding frame 4.

[0059] In this embodiment, the guide rail 41 slides into the mounting groove. This design allows the sliding frame 4 to slide along the direction of the mounting groove on the mounting base 11, thereby achieving position adjustment of the clamping structure. The second gripper 5 is disposed on the sliding frame 4. By moving the sliding frame 4, the second gripper 5 can flexibly adjust its position to accommodate the clamping of packaging foam of different sizes and positions.

[0060] In this embodiment, the position of the second gripper 5 can be adjusted manually by adjusting the position of the sliding frame 4. After the sliding frame 4 is adjusted to the appropriate position, it is locked by a locking structure to ensure that the second gripper 5 remains stable during the gripping process. The locking structure can be bolt locking, snap locking, or other mechanical locking methods to ensure that the sliding frame 4 does not shift during operation.

[0061] More specifically, scale lines are provided on the support 1. Moving the sliding frame 4 can change the specific position of the sliding frame 4 on the scale lines, thereby providing workers with a specific position reference for the sliding frame 4.

[0062] In this embodiment, the multi-functional clamping device is used as follows:

[0063] The multi-functional gripping device is mounted on the end effector of a 6-axis robot via connecting flange 21. The axis of connecting flange 21 coincides with the axis of the first gripping structure 3, ensuring the symmetry and operational accuracy of the device under the drive of the robotic arm. The position of the sliding frame 4 is manually adjusted according to the size and location of the packaging foam, allowing the second gripper 5 to precisely align with the target object. After adjustment, the sliding frame 4 is locked using a locking structure to ensure its stability during gripping.

[0064] When the compressor needs to be gripped, the robot uses programmed control to drive the cylinder 31, causing multiple first grippers 32 to open and grasp the compressor. Because the first grippers 32 are arranged in a ring, the gripping force is evenly distributed, ensuring gripping stability. After gripping, the robot places the compressor in the designated location.

[0065] When it is necessary to grip the packaging foam, the robot controls the second gripping structure to move. The second gripper 5 opens and closes to grip the packaging foam. After gripping, the robot places the packaging foam in the designated position below the compressor.

[0066] The robot assembles the grippered compressor and packaging foam, and then the conveyor line transports the assembled product to the next process.

[0067] Example 3

[0068] This embodiment is an improvement on embodiment 1.

[0069] like Figures 1-6 As shown, this embodiment provides an implementation method different from Embodiment 2. In this embodiment, the position of the sliding frame 4 can be automatically adjusted. The bracket 1 is provided with a first driving structure 6, which has two output ends, and the two output ends are respectively connected to one of the sliding frames 4;

[0070] The first drive structure 6 drives the two sliding brackets 4 to slide on the mounting base 11.

[0071] In this embodiment, a distance sensor 61 is provided on the bracket 1, and the distance sensor 61 is located between the two sliding frames 4.

[0072] In this embodiment, the position adjustment of the sliding frame 4 is achieved by the first drive structure 6, which is a dual-output motor. The two output ends of the motor are respectively connected to the two sliding frames 4 through a transmission mechanism (such as a gear or belt). The first drive structure 6 can drive the two sliding frames 4 to slide on the mounting base 11 simultaneously or separately, thereby achieving the position adjustment of the second gripper 5.

[0073] In another embodiment, the first drive structure 6 can also be a dual-axis cylinder. The two piston rods of the dual-axis cylinder are respectively fixedly connected to a sliding frame 4. The sliding frame 4 is driven by the extension and retraction of the piston rods, so that the two sliding frames 4 move closer to each other or further away from each other.

[0074] The distance sensor 61 is used to detect the distance between the sliding frames 4 in real time, or the distance between the sliding frames 4 and the target object (such as a compressor or packaging foam), providing a precise control signal to the first drive structure 6. The first drive structure 6 can precisely control the movement of the sliding frames 4. Combined with the real-time feedback from the distance sensor 61, the second gripper 5 can accurately align with the target object (packaging foam), greatly improving the gripping accuracy.

[0075] In this embodiment, the first drive structure 6 can precisely control the movement of the sliding frame 4. Combined with the real-time feedback from the distance sensor 61, the second gripper 5 can accurately align with the target object (packaging foam), greatly improving the gripping accuracy. The use of the distance sensor 61 makes the gripping operation more intelligent, automatically adjusting the position of the gripper and reducing manual intervention and errors.

[0076] By combining the first drive structure 6 and the ranging sensor 61, the position of the sliding frame 4 is automatically adjusted, reducing manual intervention and further improving the automation level of the production line.

[0077] The use of the range sensor 61 makes the gripping operation more intelligent, automatically adjusting the position of the gripper and reducing manual intervention and errors.

[0078] The automatic adjustment mechanism reduces the time required for manual adjustment of the sliding frame 4 position, improves the speed and efficiency of clamping operations, and thus enhances the overall operating efficiency of the production line.

[0079] The ranging sensor 61 of this application can be any one of an ultrasonic sensor, a laser ranging sensor 61, an infrared ranging sensor 61, and a visual ranging sensor 61.

[0080] In this embodiment, the ranging sensor 61 is an ultrasonic sensor. Specifically:

[0081] An ultrasonic sensor is mounted on each of the two sliding frames 4, with their transmission and reception directions facing each other. For example, one sensor is mounted on sliding frame 4A, facing sliding frame 4B; the other sensor is mounted on sliding frame 4B, facing sliding frame 4A. Ensure that the central axes of the two sensors are on the same horizontal or vertical plane to reduce measurement errors. During operation, one of the ultrasonic sensors (e.g., the sensor on sliding frame 4A) emits a high-frequency ultrasonic pulse. The emitted ultrasonic pulse propagates through the air and reflects back when it encounters the sensor on sliding frame 4B or its surface. The sensor on sliding frame 4A receives the reflected ultrasonic signal. The internal circuitry of the sensor records the time difference (t) between the emitted signal and the received reflected signal. Based on the speed of sound in air (v, approximately 340 m / s), the distance between the two sliding frames 4 is calculated using the following formula:

[0082] In practical applications, the ranging sensor 61 transmits the measured distance data to the controller (such as a PLC or robot control system). Based on the measured distance data, the controller adjusts the output of the first drive structure 6, driving the sliding frame 4 to move to the target position. If two ultrasonic sensors measure simultaneously, the average value can be taken as the final distance data to reduce errors.

[0083] Example 4

[0084] This embodiment is an improvement on embodiment 2 or 3.

[0085] like Figures 1-6 As shown, in this embodiment, a limiting block 12 is provided on the bracket 1, and a baffle 42 is provided on the sliding frame 4, with the limiting block 12 corresponding to the baffle 42.

[0086] A limit stop 12 is provided on the support 1, and a baffle 42 is provided on the sliding frame 4, with the limit stop 12 corresponding to the baffle 42. The cooperation between the limit stop 12 and the baffle 42 is used to limit the sliding position of the sliding frame 4, thereby preventing the sliding frame 4 from falling off the support 1. This design ensures the safety and stability of the sliding frame 4 during the sliding process, preventing equipment damage or operational errors caused by excessive sliding of the sliding frame 4.

[0087] Specifically, the limiting block 12 of this application is designed as rectangular or L-shaped. The rectangular limiting block 12 is suitable for simple linear limiting, while the L-shaped limiting block 12 can provide more complex limiting functions, such as simultaneously limiting the forward and backward and up and down positions of the sliding frame 4. The limiting block 12 is made of high-strength steel or aluminum alloy to ensure its durability and stability during long-term use. It is fixed to the bracket 1 with bolts to ensure the accuracy and stability of its installation position.

[0088] The baffle 42 is typically designed as rectangular or T-shaped. A rectangular baffle 42 is suitable for simple linear limiting, while a T-shaped baffle 42 can provide more complex limiting functions, such as simultaneously limiting the forward / backward and vertical positions of the sliding frame 4. The baffle 42 is made of high-strength steel or aluminum alloy to ensure its durability and stability during long-term use. The baffle 42 is fixed to the sliding frame 4 by bolts or welding.

[0089] The relative positions of the limiting block 12 and the baffle 42 are designed so that when the sliding frame 4 moves to its extreme position, the baffle 42 contacts the limiting block 12, thereby limiting further movement of the sliding frame 4. More preferably, the contact surfaces of the limiting block 12 and the baffle 42 are designed as smooth planes to reduce friction and extend service life. The contact surfaces can be surface-treated with wear-resistant materials to improve durability.

[0090] Example 5

[0091] This embodiment is an improvement on embodiment 1.

[0092] like Figures 1-6 As shown, in this embodiment, a specific structure for the second gripper 5 is provided. One side of the second gripper 5 is hinged to the sliding frame 4, and the sliding frame 4 is also provided with a second drive structure 53. The output end of the second drive structure 53 is hinged to the second gripper 5. The second drive structure 53 can be a cylinder, which drives the second gripper 5 to rotate on the bracket 1, thereby controlling the opening and closing of the second gripper 5.

[0093] In this embodiment, the second gripper 5 includes a base 51 and a claw hook 52. A connecting rod 54 is provided on the base 51. The connecting rod 54 is hinged to the sliding frame 4. The claw hook 52 is provided on the side of the base 51 away from the connecting rod 54.

[0094] The claw hooks 52 are L-shaped and multiple claw hooks 52 are arranged in parallel on the base 51.

[0095] The L-shaped hooks 52 of the second gripper 5 provide better gripping and securing of objects, especially softer materials such as packaging foam. The L-shaped hooks 52 offer better support and clamping force, preventing objects from slipping. Multiple L-shaped hooks 52 are arranged in parallel to accommodate packaging foam of different sizes and shapes, improving the versatility and applicability of the device. This design allows the multi-functional gripping device to flexibly meet various production needs without frequent gripper changes. The precise control of the second drive structure 53 ensures smoother opening and closing of the hooks 52, further enhancing gripping stability. Furthermore, the second drive structure 53 is cylinder-driven, enabling automatic opening and closing of the second gripper 5, reducing manual intervention and further improving the automation level of the production line.

[0096] During operation, when it is necessary to grip the packaging foam, the robot controls the second gripping structure to move. The second drive structure 53 (cylinder) drives the base 51 of the second gripper 5 to rotate, causing the claw hook 52 to open and grip the packaging foam. The L-shaped claw hook 52 design can better grasp and fix the packaging foam, especially for softer materials, providing better support and clamping force to prevent the object from slipping. After gripping, the robot places the packaging foam in the designated position below the compressor.

[0097] Example 6

[0098] like Figures 1-6 As shown, this embodiment provides a compressor production line, including a conveyor line and a robotic arm, on which a multi-functional gripping device as described above is provided.

[0099] Specifically, this embodiment has two conveyor lines, one for transporting the compressor and the other for transporting its packaging foam. The two conveyor lines are designed as continuous conveyor belts, which can transport the compressor and the packaging foam to the designated assembly position in sequence.

[0100] The compressor is transported to the assembly area via conveyor line A, which precisely delivers the compressor to the gripping position of the robotic arm.

[0101] The robotic arm moves above the compressor according to a preset program. The drive cylinder 31 of the first gripping structure 3 actuates, and multiple first grippers 32 open and grip the compressor. Because the first grippers 32 are arranged in a ring, the gripping force is evenly distributed, ensuring gripping stability. After gripping, the robotic arm places the compressor into the designated assembly position.

[0102] The packaging foam is conveyed to the gripping area via conveyor line B, which precisely delivers the foam to the gripping position of the robotic arm. The robotic arm rotates at a certain angle (90°), aligning the second gripper 5 with the packaging foam. Then, the second gripping structure is controlled to rotate; the second drive structure 53 (cylinder) drives the base 51 of the second gripper 5 to rotate, causing the claw hook 52 to open and grip the packaging foam. The L-shaped claw hook 52 design allows for better gripping and securing of the packaging foam, especially for softer materials, providing better support and clamping force to prevent slippage. After gripping, the robotic arm places the packaging foam at a designated position below the compressor.

[0103] This production line uses a multi-functional clamping device to simultaneously clamp and place the compressor and packaging foam, reducing equipment changeover time and operating steps; it also reduces manual intervention in the production process and greatly improves the production efficiency of the compressor production line.

[0104] Finally, the robotic arm assembles the gripped compressor and packaging foam, and the conveyor line then transports the assembled product to the next process. This production line, through the automated operation of the robotic arm and multi-functional gripping device, reduces manual intervention and significantly improves the production efficiency of the compressor production line. The use of the multi-functional gripping device eliminates the need to purchase and install specialized foam gripping equipment, reducing the construction cost of the production line and thus lowering the manufacturing cost of the compressor.

[0106] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0107] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
