If a performance failure is detected, the end cover needs to be disassembled to inspect the internal structure. This process is cumbersome and time-consuming. In addition, new assembly problems may arise between the reassembled end cover and outer shell, resulting in improper fit between the static and orbiting scrolls, affecting the performance of the scroll compressor. In addition, some performance failures may be caused by the initial lack of running-in between the static and orbiting scrolls. Even if the end cover is disassembled for inspection, it is difficult to find the problem, which affects judgment, wastes time, and thus affects the production efficiency of the scroll compressor.

[0026] Reference Figure 1 and Figure 2 As shown, the scroll compressor assembly device provided by an embodiment of the present invention includes a frame 100 and an assembly detection assembly 200. Optionally, the frame 100 is made of aluminum profiles and is provided with transparent panels and openable hinges around the frame 100. The frame 100 is provided with a support member 110 and a pressure member 120. The support member 110 is used to support the scroll compressor. The pressure member 120 is vertically slidably connected to the frame 100 and is located above the support member 110.

[0027] Among them, the scroll compressor includes an outer shell and an end cover. The outer shell is provided with an electromagnetically driven movable scroll, and the end cover is provided with a fixed scroll engaged with the movable scroll. The outer shell is connected to the end cover by multiple bolts.

[0028] The assembly detection component 200 includes an assembly part 210, a power connector 220, a current sensor and a controller. The power connector 220 is connected to an external regulated 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 is electrically connected to the scroll compressor. The controller is respectively communicated with the power connector 220 and the current sensor. 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 that can display the current changes of the electromagnetic device during the rotation of the movable scroll.

[0029] 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 can be 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.

[0030] It is understood that when users assemble equipment using a scroll compressor, the following steps are included:

[0031] 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 tighten it, 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 the preset torque to loosen the end cover, so that the fixed scroll on the end cover can move slightly relative to the orbiting scroll;

[0032] Step 2: Set the speed and rotation time of the movable scroll (the speed and rotation time can be set according to actual needs and will not be repeated here). Power is supplied 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.

[0033] Step 3: Observe the current changes of the movable scroll within the set time and at the set speed, and judge whether there are any mechanical structural problems of the scroll compressor based on the current changes;

[0034] 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, lift the pressure piece 120 and remove the bolts, remove the end cover and check the internal structure of the shell. After inspection, repeat the first step.

[0035] By setting the assembly part 210, the bolts can be tightened first to lock the end cover relative to the outer shell, ensuring 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, facilitating the subsequent self-adjustment of the static scroll and ensuring the running-in accuracy between the movable scroll and the static scroll.

[0036] By providing the pressure piece 120 and the assembly components, the stationary scroll and the orbiting scroll are pre-run-in at a safe speed before the formal performance test of the scroll compressor, thereby reducing product failures and losses caused by insufficient running-in during the performance test and improving the accuracy of the formal test results.

[0037] 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 any mechanical structural problems (such as insufficient 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. Without waiting for the formal performance test process, the defective items on the product machinery can be detected 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 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.

[0038] 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.

[0039] By setting up a transmission part 130, the transmission part 130 is connected to the equipment that performs other processes such as the detection equipment, internal structure installation equipment of the scroll compressor, so that the scroll compressor assembly equipment is integrated into the scroll compressor production line, realizing the assembly line production of the scroll compressor, improving the adaptability of the scroll compressor assembly equipment and the production line, and further improving the production efficiency of the scroll compressor.

[0040] Reference Figure 2 As 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 mounted 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.

[0041] 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 the time required to align the assembly part 210 and the bolt, and improving the working efficiency of the assembly equipment.

[0042] Reference Figure 3 As shown, it can be understood that the pressure 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, and 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 face of the cylinder 121 and the pressure head 1231.

[0043] By setting the spring 122, the spring 122 can add a certain amount of pressure to make the loosened end cover and the shell fit together, simulating the scenario of locking the end cover. Without 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.

[0044] 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 and ensure the accuracy of the running-in of the static scroll and the movable scroll, which will not be elaborated here.

[0045] Furthermore, the assembly part 210 includes a plurality of electric drill bits 211 . The plurality of electric drill bits 211 are arranged around the pressing member 120 , and the electric drill bits 211 correspond to the bolts one by one.

[0046] 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.

[0047] 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 respectively abut against the shell.

[0048] By providing a plurality of limiting posts 112 , the plurality of limiting posts 112 cooperate to position the housing circumferentially, thereby avoiding the problem of the housing slipping during the pre-running-in process and effectively improving the installation stability of the housing.

[0049] Furthermore, the limiting column 112 is connected to a flexible member 113, and the limiting column 112 abuts against the housing through the flexible member 113. Optionally, the flexible member 113 can be sleeved on the end of the limiting column 112, or on the outer peripheral wall of the limiting column 112.

[0050] By providing the flexible member 113 , the flexible member 113 can absorb vibrations generated during the rotation of the movable scroll, thereby maintaining a stable posture of the housing and further improving the installation stability of the housing.

[0051] Reference Figure 1 and Figure 4 As shown, it is understood that the power connector 220 includes a three-phase plug that plugs into the three-phase port on the housing. The power connector 220 is vertically slidably connected to the frame 100 and is located below the transmission member 130. 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 or a ball screw, which will not be described in detail here.

[0052] 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.

[0053] The power connector 220 is slidably mounted on the rack 100 , thereby improving the integration of the rack 100 , facilitating the coordination between the power connector 220 and the transmission component 130 , and effectively improving the working smoothness of the transmission component 130 .

[0054] Furthermore, the power connector 220 is provided with a guide post 221, and the guide post 221 is passed through the rack 100. Optionally, one guide post 221 can be provided, or a plurality of guide posts 221 can be provided at intervals along the circumference of the power connector 220.

[0055] 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 that the power connector 220 and the three-phase port on the shell are aligned, and avoid the power connector 220 from hitting the shell surface and causing damage.

[0056] The present utility model also provides a scroll compressor production line, including an end cover installation device, a performance testing device and the above-mentioned scroll compressor assembly device. The end cover installation device, the scroll compressor assembly device and the performance testing device are arranged in sequence along the transmission direction of the transmission member 130. The end cover assembly device is used to install the end cover above the outer casing and pre-embed the bolts into the end cover. The performance testing device is used to detect the performance of the assembled scroll compressor.

[0057] The scroll compressor production line provided by the embodiment of the present invention includes the scroll compressor assembly equipment described above. Therefore, the scroll compressor production line provided by the embodiment of the present invention also has the beneficial effects described in the above embodiments, which will not be repeated here.

[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
