In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] Reference Figure 1 and Figure 2 As shown, the scroll compressor assembly device provided by the embodiment of the present invention includes a frame 100 and an assembly detection component 200. Optionally, the frame 100 is composed of aluminum profiles, and transparent panels and switchable hinges are arranged around the frame 100. The frame 100 is provided with a support member 110 and a pressing member 120. The support member 110 is used to support the scroll compressor, and the pressing member 120 is slidably connected to the frame 100 in the vertical direction and is located above the support member 110.

[0030] The scroll compressor includes an outer shell and an end cover. An electromagnetically driven movable scroll is arranged in the outer shell, and a stationary scroll meshing with the movable scroll is arranged in the end cover. The outer shell is connected to the end cover by a plurality of bolts.

[0031] The assembly detection component 200 includes an assembly part 210, a power connector 220 and a controller. The power connector 220 is connected to an external voltage-stabilized power supply. The assembly part 210 is used to tighten the bolts to lock the end cover and the housing or loosen the bolts to loosen the end cover and the housing. Optionally, the assembly part 210 can be set as a manual screwdriver or an automatic electric drill. The power connector 220 is installed on the frame 100 and electrically connected to the scroll compressor. The controller is connected to the power connector 220 for communication. The controller controls the start-up and operation of the electromagnetic device in the housing through the power connector 220 and can detect the output current of the power connector 220 in real time through the current sensor. In other words, the controller can obtain the current of the power connector and control the speed and time of the movable scroll. Optionally, the controller also includes a display part, which can display the current changes of the electromagnetic device during the rotation of the movable scroll.

[0032] It should be noted that the housing can be placed directly on the surface of the support member 110, or a support column 111 can be provided on the support member 110, and the housing is placed on the support column 111. By providing the support column 111, a gap is formed between the housing and the support member 110, which facilitates the subsequent connection and installation of the power connector and improves the structural rationality of the support member 110.

[0033] It is understood that when a user assembles a device using a scroll compressor, the following steps are included:

[0034] Step 1: Install the end cover and the housing on the support member 110, then drive the pressing member 120 to press the end cover but not to tighten the end cover, then tighten the bolts through the assembly member 210 to lock the end cover, and then loosen the bolts through the assembly member 210 according to a preset torque to loosen the end cover, so that the fixed scroll on the end cover can move slightly relative to the movable scroll;

[0035] Step 2: Set the speed and rotation time of the movable scroll (the speed and rotation time can be set according to actual needs, which will not be repeated here), and supply power to the electromagnetic structure in the housing through the controller and the power connector 220, so that the movable scroll rotates at a low speed at the set time and speed;

[0036] Step 3: Observe the current change of the movable scroll within the set time and at the set speed, and judge whether there is any mechanical structural problem of the scroll compressor based on the current change;

[0037] Step 4: If there is no structural problem, lock the end cover and the shell through the assembly part 210. If there is a structural problem, raise the pressure piece 120 and remove the bolts, remove the end cover and check the internal structure of the shell, and repeat the first step after checking.

[0038] By setting the assembly part 210, the bolts can be tightened first to lock the end cover relative to the outer shell to ensure that there are no assembly problems between the end cover and the outer shell. The assembly part 210 loosens the bolts (i.e., loosens the bolts) with a preset torque to loosen the end cover and the outer shell, thereby facilitating the subsequent self-adjustment of the static scroll and ensuring the running-in accuracy between the movable scroll and the static scroll.

[0039] By providing the pressure piece 120 and the assembly components, the stationary scroll and the movable scroll are pre-run-in at a safe rotation speed before the formal performance test of the scroll compressor, thereby reducing product failures and losses caused by insufficient running-in during performance testing and improving the accuracy of the formal test results.

[0040] By observing whether the current change curve is within the error range that meets the operating requirements, it is possible to detect in advance whether there are mechanical structural problems (such as inadequate rotor magnetization, missing parts, foreign matter, jamming, and other problems that affect mechanical performance). If the current change exceeds the error range, it means that there is a structural problem with the scroll compressor. Users can directly remove the end cover for inspection, without waiting for the formal performance test process to detect the mechanical defects of the product in advance, saving the time and labor costs required to remove the locked end cover. In addition, the static scroll can follow the movable scroll to move slightly and adjust its own position, so that the static scroll and the movable scroll can reach the best matching position by themselves, thereby reducing the overall vibration and noise of the product, enhancing the performance of the scroll compressor, and improving production efficiency.

[0041] Reference Figure 1 As shown, it can be understood that the frame 100 is also provided with a transmission member 130. Optionally, the transmission member 130 is composed of two parallel guide rails 131 and a carrier 132 slidably installed between the two guide rails 131. The transmission member 130 is located below the pressing member 120 and passes through the frame 100. The support member 110 is installed on the transmission member 130. Specifically, the support member 110 is a block, plate or platform structure installed on the carrier 132.

[0042] By setting up the transmission component 130, the transmission component 130 is connected to the equipment that performs other processes such as the detection equipment of the scroll compressor, the internal structure installation equipment, etc., so that the scroll compressor assembly equipment is integrated into the scroll compressor production line, and the assembly line production of the scroll compressor is realized, the adaptability of the scroll compressor assembly equipment and the production line is improved, and the production efficiency of the scroll compressor is further improved.

[0043] Reference Figure 2As shown, it can be understood that the frame 100 is provided with a vertically movable slide 140, and the assembly part 210 and the pressing part 120 are respectively installed on the slide 140. Optionally, the slide 140 can be driven by a linear module such as a cylinder 141 and a ball screw, which will not be described in detail here.

[0044] The assembly part 210 and the pressing part 120 are both installed on the slide 140 of the frame 100 to improve the integration of the frame 100. When the slide 140 drives the pressing part 120 to press the end cover, the assembly part 210 also synchronously drives the assembly part 210 to press the bolt, saving the user's time for aligning the assembly part 210 and the bolt, and improving the working efficiency of the assembly equipment.

[0045] Reference Figure 3 As shown, it can be understood that the pressing member 120 includes a cylinder 121, a spring 122 and a telescopic rod 123, the cylinder 121 is installed on the slide 140, the telescopic rod 123 is slidably connected to the cylinder 121, a pressure head 1231 is provided at the end of the telescopic rod 123, the spring 122 is sleeved on the telescopic rod 123, and the spring 122 is respectively in contact with the end surface of the cylinder 121 and the pressure head 1231.

[0046] By setting the spring 122, the spring 122 can add a certain pressure so that the loosened end cover and the outer shell fit together, simulating the scene of locking the end cover. Under the premise of not affecting the small movement of the end cover, the structural interference between the pre-running-in static scroll and the movable scroll is avoided after the end cover is locked, thereby ensuring the accuracy of the running-in of the static scroll and the movable scroll.

[0047] It should be noted that the use of flexible parts such as rubber columns, high-density sponges, etc. to replace the cylinder 121, spring 122 and telescopic rod 123 structure can also supplement the pressure to ensure the accuracy of the running-in of the static scroll and the movable scroll, which will not be elaborated here.

[0048] Furthermore, the assembly part 210 includes a plurality of electric drill bits 211 , which are arranged around the pressing member 120 , and the electric drill bits 211 correspond to the bolts one by one.

[0049] Setting the assembly part 210 as an electrically controlled drill bit can, on the one hand, save the time and labor costs required for manually tightening the bolts, and improve the working efficiency of the scroll compressor equipment; on the other hand, the electric drill bit 211 has high control accuracy and can accurately complete the loosening step to ensure the pre-running-in effect of the static scroll and the movable scroll.

[0050] Reference Figure 4 As shown, it can be understood that the support member 110 is provided with a plurality of limiting posts 112 , and the plurality of limiting posts 112 are arranged at intervals along the circumference of the shell and abut against the shell respectively.

[0051] By providing a plurality of limit posts 112 , the plurality of limit posts 112 cooperate with each other to perform circumferential positioning on the housing, thereby avoiding the problem of the housing slipping during the pre-running-in process and effectively improving the installation stability of the housing.

[0052] Furthermore, the limiting column 112 is connected with a flexible member 113, and the limiting column 112 abuts against the housing through the flexible member 113. Optionally, the flexible member 113 may be sleeved on the end of the limiting column 112, or may be sleeved on the outer peripheral wall of the limiting column 112.

[0053] By providing the flexible member 113, the flexible member 113 can absorb the vibration generated during the rotation of the movable scroll, keep the posture of the shell stable, and further improve the installation stability of the shell.

[0054] Reference Figure 1 and Figure 4 As shown, it can be understood that the power connector 220 includes a three-phase plug that is plugged into the three-phase port on the housing, the power connector 220 is slidably connected to the rack 100 in the vertical direction and is located below the transmission member 130, and the support member 110 is provided with a through hole for the power connector 220 to pass through. Optionally, the power connector 220 can be driven by a linear module such as a cylinder, a ball screw, etc., which will not be described in detail here.

[0055] When the transmission member 130 drives the support member 110 and the scroll compressor to the bottom of the pressure member 120, the power connector 220 rises and passes through the through hole to be electrically connected to the scroll compressor; when the scroll compressor inspection is completed and the end cover is locked, the power connector 220 descends and leaves the through hole, and the transmission member 130 drives the support member 110 and the scroll compressor to the next workstation for subsequent inspection.

[0056] The power connector 220 is slidably mounted on the rack 100 , thereby improving the integration of the rack 100 , facilitating the cooperation between the power connector 220 and the transmission component 130 , and effectively improving the working smoothness of the transmission component 130 .

[0057] Furthermore, the power connector 220 is provided with a guide post 221 , and the guide post 221 penetrates the frame 100 .

[0058] By setting the guide column 221, the guide column 221 can guide the movement of the power connector 220, improve the movement stability of the power connector 220, ensure the alignment of the power connector 220 and the three-phase port on the shell, and avoid the power connector 220 hitting the shell surface and causing damage.

[0059] Reference Figure 5 As shown, the present invention also provides a scroll compressor assembly method, which is applied to the scroll compressor assembly device mentioned above, and the scroll compressor assembly method comprises:

[0060] S100, after tightening the bolts through the assembly part 210 to lock the end cover, loosen the bolts through the assembly part 210 according to a preset torque to loosen the end cover;

[0061] Specifically, the user can first install the end cover and the outer shell on the support member 110, and then drive the pressure member 120 to press the end cover but not tighten the end cover, and then tighten the bolts through the assembly part 210 to lock the end cover to ensure that there are no assembly problems between the end cover and the outer shell, and then loosen the bolts according to the preset torque through the assembly part 210 to loosen the end cover, so that the static scroll on the end cover can move slightly relative to the movable scroll, which is convenient for the subsequent self-adjustment of the scroll and ensures the running-in accuracy between the movable scroll and the static scroll.

[0062] S200, controlling the movable scroll to rotate at a preset speed and for a preset time, and obtaining the output current of the power connection member 220 to obtain a current variation curve;

[0063] Specifically, the user can set the speed and rotation time of the movable scroll through the controller. The specific values ​​of the speed and rotation time can be set according to the actual needs of the user, which will not be repeated here. During the rotation of the movable scroll, the controller can obtain the output current of the power connector 220 in real time through the current sensor, and integrate the current change curve of the power supply over time.

[0064] S300, judging whether there is a mechanical problem with the scroll compressor according to the current variation curve, if not, tightening the bolts through the assembly part 210 to lock the end cover.

[0065] Specifically, by observing whether the current change curve is within the error range that meets the operating requirements, it is possible to detect in advance whether there are mechanical structural problems (such as inadequate rotor magnetization, missing parts, foreign matter, jamming, and other problems that affect mechanical performance). If the current change exceeds the error range, it means that there is a structural problem with the scroll compressor. The user can directly remove the end cover for inspection, and can detect the mechanical defects of the product in advance without waiting for the formal performance test process, saving the time and labor costs required to remove the locked end cover. In addition, the static scroll can follow the movable scroll to move slightly and adjust its own position, so that the static scroll and the movable scroll can reach the best matching position by themselves, thereby reducing the overall vibration and noise of the product, enhancing the performance of the scroll compressor, and improving production efficiency.
