[0038] Combined Figures 1 to 6 As shown, an embodiment of the present utility model provides a fixture device for clamping an evaporator 100, which includes a carrier plate assembly 10, a clamping assembly 20 and a supporting and positioning assembly 30. The carrier plate assembly 10 is used to connect with a robot. A guiding member 11 is provided on the carrier plate assembly 10. The clamping assembly 20 and the supporting and positioning assembly 30 are respectively movably connected to the guiding member 11, and the clamping assembly 20 and the supporting and positioning assembly 30 are oppositely arranged on the same side of the carrier plate assembly 10. The clamping assembly 20 is used to clamp the side plate 101 of the evaporator 100, and the supporting and positioning assembly 30 is used to support and position the copper pipe 102 of the evaporator 100.

[0039] In this embodiment, the carrier board assembly 10 serves as a basic support structure and is used to connect to an external robot. The carrier board assembly 10 includes a guide member 11, a carrier board body 12, and a connecting arm 13. The connecting arm 13 is disposed on one side of the carrier board body 12, and the connecting arm 13 (such as a cylindrical shape) is connected to the robot. The guide member 11 is disposed on the other side of the carrier board body 12. The guide member 11 provides a track for the movable connection of the clamping assembly 20 and the supporting and positioning assembly 30, enabling the clamping assembly 20 and the supporting and positioning assembly 30 to perform smooth displacement relative to the carrier board assembly 10. The clamping assembly 20 is movably connected to the carrier board assembly 10 through the guide member 11 and can move along the direction of the guide member 11 on the carrier board assembly 10 to clamp or release the side plate 101 of the evaporator 100. By adjusting the clamping force of the clamping assembly 20, it is ensured that the side plate 101 of the evaporator 100 is clamped, preventing the side plate 101 from falling off due to shaking during the handling process. The main function of the supporting and positioning assembly 30 is to support the copper tube 102 part of the evaporator 100 to make the clamping and handling process more stable. The side plate 101 and the copper tube 102 are distributed at both ends of the evaporator 100, so the clamping assembly 20 and the supporting and positioning assembly 30 are also oppositely arranged at both ends of the carrier board assembly 10.

[0040] Specifically, when it is necessary to clamp the evaporator 100, first connect the carrier board assembly 10 to the robot. The clamping assembly 20 and the supporting and positioning assembly 30 can move relative to each other along the guide member 11 on the carrier board assembly 10 to adapt to clamping and supporting the evaporator 100. The guide member 11 can be set for the common use of the clamping assembly 20 and the supporting and positioning assembly 30, or can be set for the separate use of the clamping assembly 20 and the supporting and positioning assembly 30 respectively. Here, it can be set according to actual needs. In the following embodiments of the present utility model, the case where the clamping assembly 20 and the supporting and positioning assembly 30 share the guide member 11 is taken as an example for description. The guide member 11 in this embodiment is a guide shaft. The carrier board assembly 10 further includes a plurality of guide fixing blocks 14 and reinforcing ribs 15. The guide shaft is fixed to the carrier board body 12 through the plurality of guide fixing blocks 14. One guide fixing block 14 can be fixed at each of the two end portions of the guide shaft. In order to stabilize the guide shaft, another guide fixing block 14 can be added at the middle position of the guide shaft. In this way, there are three guide fixing blocks 14 on one guide shaft, and the number of guide fixing blocks 14 on the guide shaft can also be increased or decreased according to requirements. However, if the number of guide fixing blocks 14 is too large, it will also affect the sliding of the clamping assembly 20 and the supporting and positioning assembly 30 on the guide shaft. In addition, two guide shafts can be arranged in parallel, and the clamping assembly 20 and the supporting and positioning assembly 30 are both slidably connected to the two guide shafts to make the movement of the clamping assembly 20 and the supporting and positioning assembly 30 more stable. The plurality of reinforcing ribs 15 are arranged on the carrier board body 12 to enhance the strength of the carrier board body 12.

[0041] When the fixture device is working, the clamping assembly 20 will move to the position of the side plate 101 of the evaporator 100, clamp the side plate 101 to fix one side of the evaporator 100. The supporting assembly 30 moves under the copper pipe 102 of the evaporator 100 to support the copper pipe 102 to fix the other side of the evaporator 100, and then it is carried by the robot connected to the carrier plate assembly 10. Through the coordinated work of the fixture device and the robot, the evaporator 100 can be automatically clamped and carried, thus greatly reducing the labor intensity of manual operation, improving the work efficiency, and reducing the risk of damage to the evaporator 100 caused by improper operation.

[0042] In one embodiment, the clamping assembly 20 includes a first fixing member 21 fixedly arranged on the carrier plate assembly 10, a first movable member 22 slidably connected to the guiding member 11, and a first driving member 23 drivingly connected to the first movable member 22. The first fixing member 21 and the first movable member 22 are oppositely arranged. The first driving member 23 can drive the first movable member 22 to approach the first fixing member 21 along the direction of the guiding member 11 to clamp the side plate 101 of the evaporator 100 or move away from the first fixing member 21 to release the side plate 101 of the evaporator 100.

[0043] In this embodiment, the first fixing member 21 is fixedly installed on the carrier plate assembly 10 to provide a stable clamping reference point for the clamping assembly 20. During the operation, the first fixing member 21 remains stationary and serves as the supporting surface when the side plate 101 of the evaporator 100 is clamped. The first movable member 22 is slidably connected to the guiding member 11. The guiding member 11 provides a sliding path for the first movable member 22 along the direction of the guiding member 11, enabling it to move near the first fixing member 21 according to actual operation needs. The first driving member 23 is used to drive the first movable member 22 to move along the direction of the guiding member 11, and the first movable member 22 can move in the direction of approaching or moving away from the first fixing member 21. Specifically, when the first driving member 23 is activated, the first movable member 22 approaches the first fixing member 21 along the guiding member 11 until the side plate 101 of the evaporator 100 is clamped. On the contrary, when it is necessary to release the evaporator 100, the first driving member 23 drives the first movable member 22 to move away from the first fixing member 21, releasing the side plate 101 of the evaporator 100. The clamping assembly 20 in this embodiment realizes the clamping and release of the side plate 101 of the evaporator 100 through the cooperation of the first fixing member 21 and the first movable member 22, ensuring that the evaporator 100 can maintain a stable state during the handling process and avoiding product damage caused by improper clamping. Further, the first fixing member 21 is closer to the outside of the carrier plate assembly 10 relative to the first movable member 22 to save the occupied space of the clamping assembly 20. Further, the first driving member 23 can be a cylinder, the first fixing member 21 can be a fixing plate, the first movable member 22 can be a movable plate, and the movable plate and the fixing plate can be attached to the side plate 101 of the evaporator 100 for convenient clamping.

[0044] In one embodiment, buffer members 24 are disposed on opposite surfaces of the first movable member 22 and the first fixed member 21 .

[0045] In this embodiment, in order to further improve the stability during the clamping process and protect the side plate 101 of the evaporator 100, a buffer 24 is provided on the opposite surfaces of the first movable member 22 and the first fixed member 21 of the clamping assembly 20. The buffer 24 fits the shape of the first movable member 22 and the first fixed member 21, that is, a protective layer is added to the opposite surfaces of the first movable member 22 and the first fixed member 21. The buffer 24 directly contacts the side plate 101 of the evaporator 100, and the material of the buffer 24 can be a flexible or elastic material, such as rubber, silicone, urethane, etc., to play a role in buffering and shock absorption. By providing the buffer 24, it is possible to effectively avoid deformation or damage of the evaporator side plate 101 due to excessive clamping force during the clamping process.

[0046] During the clamping operation, the first movable member 22 is driven by the first driving member 23 to approach the first fixing member 21 to clamp the side plate 101 of the evaporator 100. When the first movable member 22 and the first fixing member 21 approach and clamp the side plate 101 of the evaporator 100, the buffer member 24 contacts the side plate 101 of the evaporator 100. Due to the flexible characteristics of the buffer member 24, the buffer member 24 can be appropriately deformed under the clamping force and evenly distribute the clamping pressure, thereby preventing the side plate 101 of the evaporator 100 from directly contacting the first movable member 22 and the first fixing member 21. When the evaporator 100 is released, the buffer member 24 can smoothly return to its original state, ensuring that the clamping device can still provide a stable buffering function during the next operation.

[0047] Furthermore, multiple reinforcing plates 211 can be added to the first fixing member 21, and the reinforcing plates 211 can strengthen the strength of the first fixing member 21, wherein at least one reinforcing plate 211 is located on the side of the first fixing member 21 away from the first movable member 22, and at least two reinforcing plates 211 are respectively located on both ends of the first fixing member 21 facing the side of the first movable member 22, wherein the reinforcing plates 211 at both ends can not only strengthen the strength of the first fixing member 21, but also play a limiting role for the side plate 101 of the evaporator 100, to prevent the side plate 101 from sliding out of the first fixing member 21 when the side plate 101 of the evaporator 100 is clamped, thereby preventing the clamping failure.

[0048] Combination Figure 7As shown, in one embodiment, the supporting component 30 includes a second movable member 31 slidably connected to the guiding member 11, a supporting member 32 disposed on the second movable member 31, and a second driving member 33 drivingly connected to the second movable member 31. The second driving member 33 can drive the second movable member 31 to approach the clamping component 20 along the direction of the guiding member 11 so as to support the copper tube 102 of the evaporator 100 through the supporting member 32.

[0049] In this embodiment, the second movable member 31 is slidably connected to the carrier plate assembly 10 through the guiding member 11 and can move under the guidance of the guiding member 11. The second movable member 31 provides movable support for the supporting member 32 to ensure that its position can be adjusted according to actual needs so that the supporting member 32 can extend under the copper tube 102 of the evaporator 100. The supporting member 32 is disposed on the second movable member 31 and is used to support the copper tube 102 of the evaporator 100, provide a supporting force, and prevent the copper tube 102 from deforming due to uneven force or external force during clamping and handling. The second driving member 33 is used to drive the second movable member 31 to move along the direction of the guiding member 11. The second driving member 33 is drivingly connected to the second movable member 31 and can control the second movable member 31 to approach or move away from the clamping component 20, thereby adjusting the contact position between the supporting member 32 and the copper tube 102 of the evaporator 100.

[0050] During the supporting operation, the second driving member 33 is activated to drive the second movable member 31 to move along the direction of the guiding member 11. When the second movable member 31 moves towards the clamping component 20, the supporting member 32 gradually approaches and supports the copper tube 102 of the evaporator 100. After the clamping component 20 clamps the side plate 101 of the evaporator 100, the supporting member 32 supports the copper tube 102 of the evaporator 100, thereby realizing the overall stable support of the evaporator 100. The design of the supporting member 32 can adjust the position according to the shape and size of the evaporator 100 to ensure that the supporting effect adapts to different types of evaporators 100. When loosening is required, the second driving member 33 drives the second movable member 31 in the reverse direction to move the supporting member 32 away from the copper tube 102. Further, the second driving member 33 can be a cylinder, and the second movable member 31 can be a movable plate.

[0051] In one embodiment, the supporting component 30 further includes an adjusting member 34. The adjusting member 34 includes a third driving member 341 disposed on the second movable member 31. The third driving member 341 is drivingly connected to the supporting member 32, and the third driving member 341 can drive the supporting member 32 to move in a direction perpendicular to the guiding member 11.

[0052] In this embodiment, the main function of the adjusting member 34 is to adjust the height position of the supporting member 32 to ensure that the supporting member 32 can exactly support the bottom position of the copper tube 102 of the evaporator 100. The third driving member 341 is installed on the second movable member 31 and is drivingly connected to the supporting member 32. The third driving member 341 can drive the supporting member 32 to move in a direction perpendicular to the guiding member 11. This moving direction enables the supporting member 32 to not only adjust the horizontal position in a direction parallel to the carrier plate assembly 10 but also move vertically up and down, so as to better adapt to the height position of the copper tube 102 of the evaporator 100.

[0053] Specifically, after the second driving member 33 drives the second movable member 31 to move away from the clamping assembly 20, the clamping assembly 20 clamps the side plate 101 of the evaporator 100, and then the third driving member 341 further adjusts the height position of the supporting member 32 to adapt to the height of the copper tube 102. After the height position is adjusted, finally, the second driving member 33 drives the second movable member 31 to move towards the clamping assembly 20 so that the supporting member 32 can support the bottom of the copper tube 102 of the evaporator 100. Driven by the third driving member 341, the supporting member 32 can move in a direction perpendicular to the guiding member 11. When the distance or angle between the copper tube 102 of the evaporator 100 and the carrier plate assembly 10 changes, the supporting member 32 can align with the position of the copper tube 102 through vertical adjustment, providing a more reliable supporting effect. Further, the third driving member 341 can be a cylinder.

[0054] In one embodiment, the adjusting member 34 further includes a third movable member 342 drivingly connected to the third driving member 341. A guiding column 343 and an elastic member 344 are connected between the third movable member 342 and the supporting member 32. The supporting member 32 can move on the guiding column 343 and compress or restore the elastic member 344 during the movement.

[0055] In this embodiment, the third movable member 342 is drivingly connected to the third driving member 341 and can move under the drive of the third driving member 341. The guide post 343 is installed between the third movable member 342 and the supporting member 32, providing a moving track for the supporting member 32, and the supporting member 32 can slide smoothly along the guide post 343. The function of the guide post 343 is to ensure that the supporting member 32 does not shift or shake during the up-and-down adjustment process. The elastic member 344 is sleeved on the guide post 343 and is connected between the supporting member 32 and the third movable member 342. The supporting member 32 can be connected by the elastic member 344 and not separated from the guide post 343, or it can be prevented from separating from the guide post 343 by setting a limiting structure at the end of the guide post 343. The evaporators 100 are stacked in piles. When it is necessary to clamp the evaporators 100, they are usually clamped one by one from top to bottom. Between two adjacent evaporators 100, the surface gap between the copper tubes 102 of the upper evaporator 100 and the surface of the lower evaporator 100 is small. Therefore, when the supporting member 32 needs to support the copper tube 102 of the topmost evaporator 100, it may contact the surface of the next evaporator 100 after descending in place. When the supporting member 32 moves along the guide post 343, the elastic member 344 can be compressed or restored. The elastic member 344 provides a certain buffering ability for the supporting member 32, can absorb part of the external force during the supporting process, avoid causing excessive pressure on the evaporator 100 below the copper tube 102 to be supported in the evaporator stack, and further reduce the risk of damage.

[0056] Specifically, the third driving member 341 is activated to drive the third movable member 342 to move. As the third movable member 342 moves, the supporting member 32 moves synchronously. When the supporting member 32 contacts the surface of the evaporator 100 below the copper tube 102 to be supported, if it encounters a large external force, the supporting member 32 will retract reversely on the guide post 343 and compress the elastic member 344. The elastic member 344 provides buffering through its elastic action. When the supporting member 32 is separated from the copper tube 102, the elastic member 344 will return to its initial state, and the supporting member 32 will return to its initial position on the guide post 343. This not only ensures that the supporting member 32 can hold the copper tube 102, but also reduces the impact and pressure that may be caused on the surface of the evaporator below the copper tube 102 to be supported during the handling process through the buffering action of the elastic member 344. Further, the third movable member 342 can be a movable plate, and the elastic member 344 can be a spring.

[0057] In one embodiment, the adjusting member 34 further includes a second fixing member 345 disposed on the second movable member 31. The output end 3411 of the third driving member 341 is connected to the third movable member 342. A guide rod 3451 is disposed on the second fixing member 345, and a guide hole 3421 for the guide rod 3451 to pass through is disposed on the third movable member 342.

[0058] In this embodiment, the second fixing member 345 is installed on the second movable member 31 and is used to provide a stable guiding structure for the third movable member 342. The main function of the second fixing member 345 is to fix the guiding rod 3451 and ensure that the moving path of the third movable member 342 does not deviate through the guiding rod 3451. The guiding rod 3451 is arranged on the second fixing member 345 and plays a role of guiding and supporting. When the third movable member 342 moves under the drive of the third driving member 341, the guiding rod 3451 guides the movement of the third movable member 342 through the guiding hole 3421, ensuring that its displacement in the vertical direction is stable and does not shift. The third movable member 342 is driven by the output end 3411 of the third driving member 341 and moves in a controlled manner through the cooperation of the guiding rod 3451 and the guiding hole 3421. The guiding hole 3421 is arranged on the third movable member 342 for the guiding rod 3451 to pass through. The guiding hole 3421 on the third movable member 342 is closely matched with the guiding rod 3451, that is, the guiding rod 3451 can slide in the guiding hole 3421. Further, the second fixing member 345 can be a fixing plate.

[0059] Combined with Figure 8 As shown, in one embodiment, the supporting and fixing assembly 30 further includes a limiting member 35. The limiting member 35 is used to limit the retracting stroke of the third movable member 342 after supporting the copper tube 102 of the evaporator 100, and / or limit the moving stroke of the second movable member 31 towards the clamping assembly 20.

[0060] In this embodiment, in order to ensure that the supporting and fixing assembly 30 is safer during operation, the supporting and fixing assembly 30 is also provided with a limiting member 35. The limiting member 35 is used to limit the moving stroke of the supporting and fixing assembly 30 to prevent the supporting member 32 or the second movable member 31 from exceeding the predetermined operating range during work. Specifically, the limiting member 35 can limit the retracting stroke of the third movable member 342 to ensure that the third movable member 342 returns to the set position after supporting the copper tube 102 of the evaporator 100 and protects the copper tube 102 from being squeezed; in addition, the limiting member 35 can also be used to limit the moving stroke of the second movable member 31 towards the clamping assembly 20 to prevent the second movable member 31 from displacing out of the predetermined range.

[0061] Specifically, the limiter 35 is used to control the range of motion of the third movable member 342 and the second movable member 31. When the fixing member 32 completes the fixing of the copper tube 102 of the evaporator 100, the third movable member 342 begins to be recovered (i.e., the entire evaporator 100 is lifted) under the action of the third driving member 341. The limiter 35 plays a limiting role at this time, ensuring that the third movable member 342 is recovered to a predetermined set position and does not exceed the normal working range. The limiter 35 can also limit the movement stroke of the second movable member 31. When the second movable member 31 moves toward the clamping assembly 20, the limiter 35 ensures that the second movable member 31 will not continue to move after reaching the limit fixing position, avoiding excessive approach to the clamping assembly 20 and causing damage to the evaporator 100 itself. Through this stroke limitation, it can be ensured that the fixing member 32 and the clamping assembly 20 maintain an appropriate distance, which can not only achieve a stable support for the evaporator copper tube 102, but also avoid mechanical damage.

[0062] Combination Figures 9 to 11 As shown, in one embodiment, the limiting member 35 is close to the clamping assembly 20 relative to the second movable member 31, and the limiting member 35 includes a limiting body 351 arranged on the carrier assembly 10 and a limiting portion 352 arranged on the limiting body 351. The limiting portion 352 is away from the clamping assembly 20 relative to the limiting body 351, and an avoidance space 3521 is provided between the limiting portion 352 and the carrier assembly 10. The avoidance space 3521 is used to avoid the second movable member 31 when the second movable member 31 moves in the direction toward the clamping assembly 20.

[0063] In this embodiment, the limiting body 351 is fixedly installed on the carrier plate assembly 10 as the basic support structure of the limiting member 35. The limiting body 351 provides a stable installation platform for the limiting portion 352 and ensures that the limiting member 35 can limit the movement stroke of the second movable member 31. The limiting portion 352 is installed on the limiting body 351 and is relatively far from the clamping assembly 20 with respect to the limiting body 351. The limiting portion 352 plays a direct limiting role. When the second movable member 31 moves towards the clamping assembly 20, the limiting portion 352 will prevent it from exceeding the predetermined stroke, preventing the second movable member 31 from colliding with or approaching the clamping assembly 20 too closely. At the same time, the limiting portion 352 has a certain length, and a corresponding avoidance opening 311 is provided on the second movable member 31. The limiting portion 352 can pass through the avoidance opening 311 to limit the third movable member 342, preventing the third movable member 342 from colliding with or approaching the second fixing member 345 too closely during the movement process. An avoidance space 3521 is formed between the limiting portion 352 and the carrier plate assembly 10. The avoidance space 3521 is provided to provide room for avoidance of a part of the structure of the second movable member 31 when the second movable member 31 moves towards the clamping assembly 20, preventing the second movable member 31 from interfering with the limiting member 35. When the second movable member 31 approaches the limiting portion 352, the avoidance space 3521 allows a part of the structure to pass through, so as to ensure that the second movable member 31 can move freely within the set range without being hindered.

[0064] Since the movement principle and process of the clamping assembly 20 are relatively simple, the movement principle and process of the supporting and positioning assembly 30 will be described in detail below.

[0065] Specifically, as Figure 9 shown, at this time, the supporting and positioning assembly 30 is in the initial state. In the initial state, the second driving member 33 is in the extended state, that is, the second movable member 31 has been pushed outwards (i.e., in the direction away from the clamping assembly 20) by a certain distance, and the third driving member 341 is in the retracted state, that is, the supporting member 32 has not been pushed downwards; as Figure 10 shown, the third driving member 341 is in the extended state, that is, the supporting member 32 has been pushed downwards by a certain distance. At this time, the second driving member is still in the extended state, that is, the second movable member still remains in the state of being pushed outwards; as Figure 11As shown, the third driving member 341 is still in the extended state, that is, the supporting member 32 still maintains the state of being pushed downward, while at this time the second driving member 33 is in the retracted state, that is, the second movable member 31 is retracted inward, so that the supporting member 32 extends to the bottom of the copper tube 102 to be supported, and finally it can be carried by the robot. During the above movement process, the movement of the clamping assembly 20 and the robot is also accompanied. Specifically, the robot first moves the entire fixture device to the top of the stacked evaporators 100. At this time, the supporting assembly 30 is in the initial state, and the clamping assembly 20 is also in the unclamped state. Then, the first driving member 23 in the clamping assembly 20 is used to drive the clamping side plate 101. After clamping in place, the robot moves horizontally for a certain distance, so as to pull the evaporator 100 outwards for a certain distance to prevent interference from the evaporator 100 below, and then control the supporting assembly 30 in the aforementioned order to support the copper tube 102.

[0066] In one embodiment, the supporting member 32 includes a supporting body 321 and a supporting portion 322 provided on the supporting body 321. The supporting portion 322 faces the clamping assembly 20 relative to the supporting body 321, and the thickness of the supporting portion 322 is smaller than the thickness of the supporting body 321.

[0067] In this embodiment, the supporting body 321 is the main supporting structure of the supporting member 32, having a relatively large thickness and strength to ensure that the supporting member 32 has sufficient load-bearing capacity when supporting the copper tube 102 of the evaporator 100. The supporting body 321 is connected to the third movable member 342 through the guiding column 343 and the elastic member 344, and the vertical movement of the supporting member 32 can be realized by the driving of the adjusting member 34. The supporting portion 322 is provided at the front end of the supporting body 321 and extends in the direction facing the clamping assembly 20 relative to the supporting body 321. The main function of the supporting portion 322 is to contact the copper tube 102 of the evaporator 100 and play a role in supporting the copper tube 102. When the second movable member 31 drives the supporting member 32 to move below the copper tube 102 of the evaporator 100, the supporting portion 322 will contact and support the copper tube 102. The gap between the copper tubes 102 of the upper evaporator 100 and the lower evaporator 100 is relatively small. Setting the supporting portion 322 to have a relatively small thickness relative to the supporting body 321 helps to extend into the gap to support the copper tube 102.

[0068] This embodiment also provides a handling mechanism, including the fixture device as described above, and further including a robot, and the robot is connected to the carrier plate assembly 10 of the fixture device.

[0069] Combined with Figure 12 and Figure 13As shown in the figure, an automatic handling method for a handling mechanism is also provided in an embodiment of the present utility model. This method can efficiently and accurately transport the neatly stacked evaporators 100 to the drying production line. The specific steps are as follows:

[0070] Step 1: Stack the evaporators 100 stacked according to rules (fixed direction, fixed number of layers) at the designated position. At this time, the side plates 101 and copper tubes 102 of the evaporators 100 are neatly stacked in the set direction (as Figure 12 shown), which facilitates subsequent automatic handling operations.

[0071] Step 2: The robot controls the fixture device to move to the set position above the evaporator 100, and the clamping component 20 on the fixture device is activated to clamp the side plate 101 of the uppermost evaporator 100.

[0072] Step 3: After clamping the side plate 101 of the evaporator 100, the robot moves a certain distance (such as 20 cm) in the direction of the side plate to push the evaporator 100 to move synchronously. This can cause the clamped evaporator 100 to displace relative to the evaporator 100 below, that is, the copper tube 102 opposite to the side plate 101 moves away from the evaporator 100 below, thereby leaving enough space for subsequent operations and making the evaporator 100 partially suspended (as Figure 13 shown).

[0073] Step 4: When the copper tube 102 of the evaporator 100 opposite to the side plate 101 moves away from the evaporator 100 below, the supporting component 30 on the fixture device starts to work. Driven by multiple driving parts, the supporting piece 32 is extended into the bottom gap of the copper tube 102 of the suspended evaporator 100. An elastic piece 344 is provided between the supporting piece 32 and the third movable piece 342. Therefore, the supporting piece 32 has elasticity and can closely adhere to the surface of the next evaporator 100 without crushing it, while firmly supporting the copper tube 102 part of the evaporator 100 to ensure the stability of the evaporator 100 during the handling process.

[0074] Step 5: When the clamping component 20 clamps the side plate 101 of the evaporator 100 and the supporting component 30 supports the copper tube 102 of the evaporator 100, the clamping operation of the evaporator 100 is completed. At this time, the robot starts to move and transports the clamped evaporator 100 to the fixed position on the drying production line. After reaching the drying production line, the clamping component 20 and the supporting component 30 release the clamped evaporator 100, and it is smoothly placed at the designated position on the drying production line, completing one handling operation of the evaporator 100.

[0075] Step 6: After transporting an evaporator 100 to the drying production line, the robot returns to the stacking position of the evaporators 100 and repeats the operations in Steps 2 to 5 to transport the evaporators 100 layer by layer from top to bottom until all the evaporators 100 are transported to the drying production line, thus completing the unstacking operation of the evaporators 100.

[0076] Through the cooperation of the robot and the fixture device, the utility model can efficiently and safely complete the automatic clamping and transportation of the evaporator 100, reduce the labor intensity of manual operation, and at the same time reduce the risk of damage to the evaporator during the clamping and transportation process, greatly improving the work efficiency and product quality.

[0077] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the protection scope of the claims.
