This allows the carrier to accommodate evaporator assembly of varying sizes and models. Furthermore, the carrier's inherent compression mechanism prevents the entire assembly from falling and surface damage during transport. This improves the carrier's versatility and evaporator surface quality, minimizing damage to the evaporator's fins.

[0034] 2. The compacting carrier as a whole and the evaporator material are transported and moved by the handling fixture in the compacting carrier and its handling fixture. One end of the compacting carrier is mounted on the sixth axis of the industrial robot, and the other end is assembled with the positioning parts of the compacting carrier. The carrier can be transported and moved firmly and stably, which promotes the realization of the carrier's material compaction and automatic handling functions.

[0035] Implementation Case 1:

[0036] like Figure 1 As shown in the figure, the compact carrier and its handling fixture of the present invention mainly consist of a compact carrier 1, a handling fixture 2, and an air conditioner indoor evaporator 3. The air conditioner indoor evaporator 3 is stored in various positions inside the compact carrier 1. The handling fixture 2 and the compact carrier 1 can be used together to form a whole or separately.

[0037] in, Figure 2The compression carrier 1 consists of a carrier base plate 11, a carrier soft bottom pad 12, a mouth-shaped positioning block 13, a carrier connecting plate 14, an L-shaped support plate 15, an RFID tag 16, a buffer block 17, a rocker arm fixing plate 18, a swing arm 19, a backrest support rod 110, a backrest plate 111, a spacer 112, a cushion 113, a fixing plate 114, a pressure plate 115, a pressure pad 116, etc. The L-shaped support plates 15 are fixed to both sides of the carrier bottom plate 11 respectively, and the carrier connecting plate 14 connects the two L-shaped support plates 15 for strengthening the fixation; the spacer 112 and the cushion 113 are fixed to the backrest plate 111 according to different work positions, and the fixing plate 114 fixes the cushion 113 firmly. The backrest plate 111 is connected to the upper end of the L-shaped support plates 15 on both sides through the backrest support rod 110. The forward extension length of the backrest plate 111 is adjusted by its own bolts and nuts to indirectly change the angle of the evaporator when it is tilted, so as to adapt to different models; the connecting carrier soft bottom pad 12 is fixed to the upper surface of the carrier bottom plate 11 to protect the bottom of the evaporator from damage; the buffer block 17 is fixed to the carrier bottom plate The ends of the carrier 11 act as buffers between adjacent carriers on the line; the mouth-shaped positioning block 13 is fixed to the middle of the carrier connecting plate 14 and cooperates with the middle positioning block 28 in the handling fixture 2 to perform positioning and fixing functions; the RFID tag 16 is fixed to the L-shaped support plate 15 to record the helium inspection pass and fail information of the evaporator carried by the entire set of carriers; the swing arm fixing plate 18 is fixed to each end of the carrier connecting plate 14 and connected to one end of the swing arm 19. The swing arm 19 can swing relative to the swing arm fixing plate 18. The pressure pad 116 is installed on the pressure plate 115, and its two ends are respectively fixed to the ends of the swing arm 19 on both sides, forming a whole with the swing arm 19. When the swing arm 19 swings, the pressure plate 115 rises and falls, facilitating the compaction of the evaporator material inside the carrier. The carrier's soft bottom pad 12, spacer 112, cushion 113, and pressure pad 116 are all made of soft silicone material, which plays a role in protecting the fins on the surface of the evaporator and preventing the evaporator surface from being damaged due to shaking operation inside the carrier.

[0038] in, Figure 3 The handling fixture 2 is composed of a fixture base plate 21, a positioning block 22, a sensor bracket 23, a swing pressure rod 24, a swing cylinder 25, an L-shaped mounting plate 26, a connecting flange 27, an intermediate positioning block 28, etc. One end of the connecting flange 27 is fixed to the side of the fixture base plate 21, and the other end can be used to connect the sixth axis of the industrial robot; the positioning block 22, the sensor bracket 23, the L-shaped mounting plate 26, the intermediate positioning block 28, etc. are respectively fixed to different positions of the fixture base plate 21 to form a whole with the fixture base plate 21. The fixed side of the swing cylinder 25 is installed on the L-shaped mounting plate 26, and the swing side is connected to the swing pressure rod 24 to control its swing and transmit the swing force. The intermediate positioning block 28 and the mouth-shaped positioning block 13 are mutually fitted for positioning, and the positioning block 22 is respectively fitted with the two grooves in the carrier connecting plate 14.

[0039] like Figure 4 As shown, the working principle and structure of the compacting carrier and its handling fixture of the present invention are composed of a compacting carrier 1, a handling fixture 2, an air conditioner indoor unit evaporator 3, a positioning block 4, a double-speed line 5, a helium detection equipment 6, a carrier positioning frame 7, and an industrial robot 8. The handling fixture 2 is fixed to the end of the sixth axis of the industrial robot 8 to facilitate its controlled movement; the positioning block 4 is installed below the material removal and placement positions of the double-speed line 5 to separate and position carriers loaded with materials on the line to prevent the line from connecting and affecting the robot's handling movement; the carrier positioning frame 7 is fixed inside the box of the helium detection equipment 6 to place the compacting carrier 1 so that the pressure plate 115 in the compacting carrier 1 is in the upper position, facilitating the helium detection equipment to perform vacuum helium leak detection and facilitating the robot and fixture to be moved out of the inside of the helium detection equipment 6.

[0040] Run the design:

[0041] like Figure 4 As shown, the working principle and structure of the compacting carrier and the handling fixture of the present invention are as follows: Figure 4 This is a working principle diagram of the compacting carrier and its handling fixture of the present invention, combined with Figures 1 to 4As shown, first, the compacting carrier 1 fully loaded with evaporators flows down from the upper segment of the double-speed line 5 and reaches the material picking position of the line. The cylinder in the positioning block rises to stop and position the compacting carrier 1. Then the industrial robot 8 moves with the handling fixture 2 to the side end of the compacting carrier 1, and through the moving action, the middle positioning block 28 and the mouth-shaped positioning block 13, the positioning block 22 and the two grooves in the carrier connecting plate 14 are respectively fitted and fixed. At the same time, the swing cylinder 25 in the handling fixture 2 is actuated, driving the swing pressure rod 24 to swing and rotate, so that the swing pressure rod 24 is pressed on one end of the swing rod 19 in the compacting carrier 1, and the lever principle is cleverly used to lift the pressure plate 115, so that the pressure pad 116 presses the various evaporator materials in the compacting carrier 1 and maintains the compacted state. Under the control of the industrial robot 8, the carrier is slowly lifted up as a whole to separate from the double-speed line 5 and move to the door of the helium inspection equipment 6 box. After opening, the entire carrier is slowly placed on the carrier positioning frame 7. The vertical frame in the carrier positioning frame 7 supports the pressure plate 115, and the swing cylinder 25 in the handling fixture 2 is activated, driving the swing pressure rod 24 to swing and rotate, causing the swing pressure rod 24 to disengage from one end of the swing rod 19 in the compression carrier 1 (at this time, the pressure plate 11 remains lifted and compressed due to the support of the carrier positioning frame 7). Under the control of the industrial robot 8, the handling fixture 2 is slowly disengaged from the compression carrier 1 and removed from the interior of the helium inspection equipment 6. The door of the box is then closed for the helium inspection operation. After the helium inspection is completed, the helium inspection information is transmitted to the RFID tag 16 for recording. At the same time, the door of the box is opened. Under the control of the industrial robot 8, the handling fixture 2 is slowly fixed to the compression carrier 1 and removed from the interior of the helium inspection equipment 6. It is transported to the position above the double-speed line 5 and slowly placed on the double-speed line 5 for the next process. At this point, a helium inspection cycle is completed, and the operation can be repeated to perform continuous helium inspection operations. At this point, the purpose of moving the helium inspection equipment in and out of the helium inspection process of the air conditioner indoor unit evaporator is achieved.

[0042] The main function of the present invention is that the soft bottom pad of the compression carrier and the carrier in the transport fixture thereof has a certain tilt angle. When the evaporator is placed on it, it naturally leans against the rear side of the carrier, which is convenient for manual installation of the upper parts of the evaporator. At the same time, the evaporator is stably placed inside the carrier, which is convenient for subsequent transportation.

[0043] The cushions, spacers, pressure pads and other parts in this clamping carrier and its handling fixture are made of soft protective silicone material. After the evaporator is placed inside each workstation of the carrier, the fins on the surface of the evaporator are protected, effectively preventing the fins on the surface of the evaporator from shaking and touching hard objects, causing damage such as fin flipping, thereby ensuring product quality.

[0044] The pressure plate, swing lever, and swing pressure lever in this clamping carrier and its handling fixture can be adjusted to the appropriate position according to actual needs. When the clamping carrier moves on the conveyor line, the pressure plate is held low by gravity, facilitating manual placement of evaporator materials at various workstations within the carrier and installation of corresponding accessories. When helium inspection is required, the swing pressure lever in the handling fixture cleverly utilizes the principle of leverage to rotate the swing lever, lifting the pressure plate from the bottom and pressing it against the evaporator inside the carrier, thereby securing it. This prevents the evaporator from shaking, shifting, or falling within the carrier during handling when the carrier is removed from the assembly line, thus protecting the evaporator product.
