Technical Field
[0001] This invention belongs to the field of brushless motor assembly technology, and in particular relates to an assembly line for the motor in a brushless compressor. Background Technology
[0002] The assembly of a brushless motor involves the assembly of many components such as counterweights, drive pins, PCB boards, and heat sinks. Furthermore, both the stator and rotor have a certain magnetic force, and during manual installation, there will be a repulsive force between the stator and rotor, making installation difficult.

[0038] In the process of inserting the rotor into the cylinder, the bearing at its front end, which is inserted into the counterweight block, is usually inserted into the cylinder for assembly. The conventional solution is to press the rear end of the rotor to connect the front end to the cylinder. However, this can easily lead to damage to the rotor due to insufficient axial accuracy, resulting in a rigid connection between the rotor and the cylinder. Alternatively, the bearing at the front end of the rotor may move on the rotor shaft, resulting in insufficient connection strength between the rotor and the cylinder. Therefore, by setting up rotor positioning fixture 2, workpiece pressing assembly, fixture drive assembly, fixture release assembly, cylinder positioning fixture and cylinder fixing assembly, the pressing assembly presses the structural part connecting the rotor and the cylinder during operation. This ensures that only this part of the rotor bears pressure during assembly, without damaging other parts of the rotor structure, thus guaranteeing the product yield.
[0039] Among them, the structure of rotor assembly pressing equipment II enables simultaneous feeding of the drive pin and counterweight B. The working mode of the whole equipment can complete the combination of drive pin, counterweight B and rotor within a small mechanical running path, effectively saving time and improving efficiency.

[0076] Among them, see Figure 2 , Figure 3 The pressing equipment for rotor 50 and counterweight A51 includes rotor positioning fixture 14, rotor 50 fixing assembly, counterweight picking assembly 13, and pressing assembly 12. The rotor 50 fixing assembly is used to fix rotor 50 within rotor positioning fixture 14. The counterweight picking assembly 13 is used to pick up counterweight A51. The pressing assembly 12 is used to control the counterweight picking assembly 13 to press counterweight A51 onto rotor 50. Specifically, rotor positioning fixture 14 is a single piece with a slot on its side wall, into which rotor 50 is horizontally inserted. This allows the bearing above it to hang on the block. The rotor 50 fixing assembly includes two rotor fixing cylinders 15. The working end of each rotor fixing cylinder 15 is fixed with a conical rod 16. The rod is inserted into the rotor positioning fixture 14 in the horizontal direction and blocks the rotating shaft on the rotor 50, preventing it from detaching from the rotor positioning fixture 14. This design can avoid damage to the rotor 50 caused by hard contact between the rotor 50 fixing assembly and the rotor 50. The counterweight material handling assembly 13 can be a negative pressure suction head, and the pressing assembly 12 can be a linear cylinder.
[0077] Among them, see Figures 4-9 The rotor assembly 30 pressing device includes a rotor positioning fixture 3, a workpiece clamping assembly 6, a fixture driving assembly 5, a fixture disengagement assembly, a cylinder positioning fixture 4, and a cylinder 49 fixing assembly.
[0078] The rotor positioning fixture 2 3 includes two overlapping grooves 301 to achieve axial positioning of the rotor 50.
[0079] The workpiece clamping assembly 6 can clamp against the back of the structure that is combined with the cylinder 49 on the rotor 50;
[0080] The tooling drive assembly 5 is used to drive the rotor positioning tool 2 3 to drive the rotor assembly 30 to combine with the cylinder 49.

[0082] The rotor assembly 30 pressing equipment includes a workbench 1 (work frame), on which a rotor positioning fixture 2 3, a workpiece clamping assembly 6, a fixture driving assembly, a fixture disengagement assembly, a cylinder positioning fixture 4, and a cylinder 49 fixing assembly are provided.
[0083] The rotor positioning fixture 2 3 includes two overlapping grooves 301 to achieve axial positioning of the rotor 50 with the counterweight A51. Specifically, one overlapping groove 301 is used to overlap the rotating shaft on the rotor assembly 30, and a positioning overlapping block 302 is present at the end of the rotor assembly 30 away from its insertion into the cylinder 49. The positioning overlapping block 302 overlaps with another overlapping groove 301 that matches its side. The positioning overlapping block 302 achieves horizontal positioning (see...). Figure 7 );
[0084] The workpiece clamping assembly 6 can abut against the back of the bearing that is combined with the cylinder 49 on the rotor assembly 30 (see...). Figure 5 Its abutting position can be observed).
[0085] The tooling drive assembly 5 is used to drive the rotor positioning tool 2 3 to drive the rotor assembly 30 to combine with the cylinder 49.
[0086] The tooling release assembly is used to drive the rotor positioning tool 2 3 to move so that the rotor assembly 30 is released from the overlapping groove 301.
[0087] Among them, see Figure 4 , Figure 5 The worktable 1 is provided with a slide table 2. The rotor positioning fixture 3 and the workpiece clamping assembly 6 are both provided on the slide table 2. The workpiece clamping assembly 6 includes a clamping head 61 and a clamping drive assembly 62. The movement path of the clamping head 61 driven by the clamping drive assembly 62 is at an angle to the direction in which the rotor assembly 30 is assembled into the cylinder 49. The clamping drive assembly 62 can be a linear cylinder.
[0088] Among them, see Figure 1 , Figure 2 , Figure 3The slide 2 is also provided with a pressure-bearing component 7, which includes a pressure-bearing block 71 and a pressure-bearing drive component 72. When one end of the clamping head 61 abuts against the rotor assembly 30, the pressure-bearing drive component 72 controls the pressure-bearing block 71 to move to the other end of the clamping head 61. Specifically, there is a snap-fit surface 63 at the other end of the clamping head 61. The pressure-bearing drive component 72 controls the pressure-bearing block 71 to move to the snap-fit surface 63 to snap the pressure-bearing block 71. The pressure-bearing drive component 72 can be selected as a linear cylinder.
[0089] Among them, see Figure 4 The tooling drive assembly includes a tooling drive cylinder, which drives the slide 2 to move, thereby driving the tooling to move.
[0090] Among them, see Figure 7 The tooling detachment assembly includes a detachment cylinder 10 mounted on the slide table 2, and the rotor positioning tool 2 3 is disposed at the tooling end of the detachment cylinder 10.
[0091] Among them, see Figure 7 The slide table 2 is also provided with a tooling limiter 11. After the disengagement cylinder 10 drives the rotor positioning tool 2 3 to abut against the tooling limiter 11, the rotor positioning tool 2 3 is positioned.
[0092] Among them, see Figure 8 , Figure 9 The cylinder body 49 fixing assembly includes a combination direction fixing assembly 8 and a vertical direction fixing assembly 9. The cylinder body positioning fixture 4 has an abutment plate 401 to cooperate with the combination direction positioning assembly to fix the cylinder body 49 in the combination direction. The vertical direction fixing assembly 9 is used to fix the cylinder body 49 in the cylinder body positioning fixture 4. The combination direction fixing assembly 8 includes a clamping rod 82 and a combination direction driving assembly 81. The cylinder body 49 has a protrusion. The end of the clamping rod 82 is provided with a direction correction groove 84 that can be sleeved on the protrusion. The combination direction driving assembly 81 can be a cylinder. The vertical direction fixing assembly 9 can be two rotating downward pressing cylinders to press the cylinder body 49 on both sides respectively.
[0093] When using this equipment, the rotor assembly 30 and cylinder 49 can be loaded manually or by other machines. Then, the cylinder 49 fixing assembly is activated to limit and fix the cylinder 49 within the cylinder positioning fixture 4. Next, the workpiece pressing assembly 6 is activated to control the pressing head 61 to align and press the back of the front end of the rotor assembly 30. Then, the pressure bearing assembly 7 is activated to block the pressure block 71 at the abutment surface behind the abutment block to prevent it from moving backward under force. Next, the fixture driving assembly 5 drives the slide table 2 to move along a guide rail to assemble the rotor assembly 30 and cylinder 49. After assembly is completed, the disengagement cylinder 10 controls the rotor positioning fixture 2 3 to move downward to separate it from the rotor assembly 30. Then, the other workpieces are reset, and finally, the disengagement cylinder 10 is reset, and the position of the rotor positioning fixture 2 3 is ensured by the fixture limiting component 11.
[0094] Among them, see Figure 10 The rotor assembly 30 pressing device two includes a transmission pin positioning fixture 20, a counterweight block picking component two 18, a rotor assembly positioning fixture one 19, a moving component one 21, and a pressing component two 17. The rotor assembly positioning fixture one 19 is used to place the cylinder 49 containing the rotor 50. The moving component one 21 is used to control the transmission pin positioning fixture 20 and the rotor assembly positioning fixture one 19 to be positioned below the working end of the pressing component. The counterweight block picking component two 18 is positioned at the working end of the pressing component two 17 to press the counterweight block and transmission pin 52 together, and to press the pressed counterweight block and transmission pin 52 onto the rotor 50. The rotor assembly 30 pressing device two also includes a shaft center positioning component. The rotor positioning assembly includes a rotor shaft positioning cylinder 22 and a rotor shaft positioning rod 23 located at the end of the rotor shaft positioning cylinder 22. Specifically, since the transmission pin 52 is a cylindrical pin, the transmission pin positioning fixture 20 can be a circular groove opened on the block. The transmission pin positioning fixture 20 and the rotor assembly positioning fixture 19 are jointly arranged on a plate, which slides on a guide rail. The moving component 21 can be a cylinder-driven linear moving mechanism, which drives the aforementioned plate to move so that the transmission pin positioning fixture 20 and the rotor assembly positioning fixture 19 can be respectively placed under the pressing component 2 17. The counterweight removal component 2 18 can be a negative pressure suction head, and the pressing component 2 17 can be a cylinder.
[0095] When using the rotor assembly 30 pressing device 2, the rotor assembly 30 can be manually placed onto the rotor assembly positioning fixture 19. The counterweight B53 is placed at the counterweight removal component 2 18 for it to be picked up. The transmission pin 52 is placed into the transmission pin positioning fixture 20. Then the equipment is started, and the rotor shaft positioning cylinder 22 drives the rotor shaft positioning rod 23 to move downward and insert into the rotor 50 to ensure the shaft is accurate. The end of the rotor shaft positioning rod 23 is tapered to adjust the insertion when there is a slight deviation in the positioning of the rotor assembly 30. Then the pressing component 2 17 presses down to press the counterweight B53 into the transmission pin 52. Then the counterweight removal component 2 18 picks up the assembled transmission pin 52 and rises. The moving component 1 21 controls the rotor assembly 30 to be placed below the pressing component 2 17. The pressing component 2 17 presses down to complete the assembly of the transmission pin 52 in the rotor assembly 30.
[0096] Among them, see Figures 11-14 The stator assembly 31 pressing equipment includes a worktable 1, on which a workpiece pressing assembly is provided; the workpiece pressing assembly includes a stator assembly positioning fixture 25, a rotor assembly positioning fixture 24, an axial positioning assembly 27, and a material handling pressing assembly 26; the axial positioning assembly 27 includes an axial positioning rod 272 and a positioning drive assembly 271 that drives the axial positioning rod 272 to move axially, and the stator assembly 31 has an axial positioning hole for the axial positioning rod 272 to be inserted; the material handling pressing assembly 26 includes A set of material-picking clamping blocks 263, a clamping drive assembly 262 that controls the material-picking clamping blocks 263 to clamp or release, and a pressing drive assembly 261 that controls the clamping drive assembly 262 to move along the axial direction of the positioning rod. The material-picking clamping blocks 263 can clamp the stator assembly 31 on the stator assembly positioning fixture 1 25 and transfer it to the rotor assembly positioning fixture 24. The clamping drive assembly 262 can be a finger-grip cylinder. There are two material-picking clamping blocks 263, and the surface that clamps the stator assembly 31 is consistent with the contour of its clamping position.
[0097] A mounting bracket 266 is fixed on the workbench 1, and a vertically arranged guide rail 264 is mounted on the mounting bracket 266. The positioning drive component 271 and the clamping drive component 262 are jointly mounted on a mounting plate 265. The mounting plate 265 slides on the guide rail 264. The pressing drive component 261 drives the mounting plate 265 to move axially along the positioning rod. A guide positioning block 273 is connected to the mounting plate 265 through a connecting seat 274. The guide positioning block 273 has a guide hole, and the axial positioning rod 272 passes through the guide hole. The pressing drive component 261 can be a linear moving mechanism driven by a motor, and the positioning drive component 271 can be a cylinder.
[0098] The workbench 1 is also equipped with a tooling mounting platform 33 and a mounting platform drive assembly 34. The stator assembly positioning tool 1 25 and the rotor assembly positioning tool 24 are both mounted on the tooling mounting platform 33. A guide rail 2 32 is installed on the workbench 1, and the tooling mounting platform 33 slides on the guide rail 2 32. The mounting platform drive assembly 34 is used to drive the stator assembly positioning tool 1 25 and the rotor 50 positioning tool 24 to be placed sequentially below the working end of the material handling and pressing assembly 26. The mounting platform drive assembly 34 can be a selected cylinder, and the selected cylinder has two working strokes.

[0100] The workbench 1 is also equipped with an in-situ detection sensor 29 for detecting whether there is a workpiece on the rotor assembly positioning fixture 24 and the stator assembly positioning fixture 25. Specifically, an infrared sensor or the like can be used.
[0101] In this solution, when using the equipment, the rotor assembly 30 first needs to be placed on the oiling positioning fixture 283 for oiling. Simultaneously, the stator assembly 31 is placed on the stator assembly positioning fixture 25. After the rotor assembly 30 is oiled, the placement platform drive assembly 34 is activated, positioning the stator assembly positioning fixture 25 below the material handling and pressing assembly 26. Simultaneously, the rotor assembly positioning fixture 24 is positioned between the oiling assembly 283 and the stator assembly positioning fixture 25.
