Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting equipment, in particular to press-fitting equipment for connectors of new energy motor controllers. Background Art

[0002] During the production process of new energy motor controllers, the connectors on the control board need to be press-fitted against the driver board on the controller assembly. Existing methods for press-fitting connectors on control boards generally include manual assembly, semi-automatic equipment assembly, and fully automatic assembly. Manual assembly, however, is labor-intensive and time-consuming, while semi-automatic assembly requires manual loading, which can easily damage the control board. Therefore, fully automatic assembly is generally preferred. Existing press-fitting equipment generally consists of a workbench, an automatic loading robot, a press fixture, a press table, and a cylinder for driving the press table. During use, the automatic loading robot sequentially loads the connector control board and driver board, and then the cylinder drives the press table downward to complete the process.

Multiple positioning holes are provided on the control board. It is characterized in that: a controller installed on one side of the workbench 1, a lower tray 2 fixed on the workbench 1, an upper tray installed above the lower tray 2, a tray driving assembly 3 used to drive the upper tray to close or separate, a pressing table 4 arranged directly above the upper tray, a press-fitting seat 5 arranged above the pressing table 4, a pressing cylinder assembly 6 used to drive the press-fitting seat 5 to rise or fall, and multiple groups of positioning assemblies 7 used to connect the press-fitting seat 5 and the pressing table 4. Multiple suction cups 8 and multiple positioning columns 9 are provided at the bottom of the pressing table 4. The positioning columns 9 are arranged opposite to the positioning holes. The automatic loading manipulator, the tray driving assembly 3, and the pressing cylinder assembly 6 are all electrically connected to the controller.

[0025] During use, the automatic loading manipulator loads the controller assembly with the driving board onto the lower tray 2. The tray driving assembly 3 drives the upper tray to close. The automatic loading manipulator loads the control board onto the upper tray. The pressing cylinder assembly 6 drives the press-fitting seat 5 to move the pressing table 4 downward. During the downward movement, the positioning columns 9 gradually insert into the positioning holes on the control board. At the same time, the positioning assembly 7 positions the control board until the suction cups 8 suck the upper surface of the control board. The pressing cylinder assembly 6 drives the press-fitting seat 5 to move the pressing table 4 upward. The tray driving assembly 3 drives the upper tray to separate. The pressing cylinder assembly 6 drives the press-fitting seat 5 to move the pressing table 4 downward until the control board is press-fitted with the driving board on the lower tray 2. The suction cups 8 release the control board. Then the pressing cylinder assembly 6 drives the press-fitting seat 5 to move the pressing table 4 upward. This utility model can accurately position the control board and the driving board after the automatic loading manipulator loads the materials, avoiding the situation of damage to the control board caused by inaccurate positioning, and ensuring the normal use of the new energy motor controller connector after press-fitting.

[0026] As Figure 1-7As shown, the upper tray includes a front tray 101 and a rear tray 102; the tray driving component 3 includes two support columns 31 fixed to the bottom end on the workbench 1, a C-shaped plate 32 with its vertical part fixedly connected to the top ends of the two support columns 31. Tray driving cylinders 33 are respectively fixed to the end parts of the transverse part of the C-shaped plate 32. The piston rod heads of the two tray driving cylinders 33 are respectively connected to the front tray 101 and the rear tray 102. When the piston rod heads of the tray driving cylinders 33 are in the extended state, the front tray 101 and the rear tray 102 are spliced to form the upper tray; in this embodiment, by the telescopic movement of the piston rod heads of the two tray driving cylinders 33, the two front trays 101 and the rear tray 102 are driven to close or separate. When the front tray 101 and the rear tray 102 are in the closed state, the upper tray is located directly below the pressing table 4.

[0027] As Figure 1-7 shown, a round head 91 is provided at the bottom end of the positioning column 9. A plurality of through holes 41 are vertically provided on the pressing table 4. Blind holes 42 are respectively provided at the top end and the bottom end of the through holes 41; the positioning component 7 includes a fixed ring 71 fixed in the blind hole 42, a positioning shaft 72 movably connected in the through hole 41, and a movable ring 73 arranged opposite to the fixed ring 71.

A plurality of positioning steel balls 74 are rollingly connected in the annular groove 711. The positioning steel balls 74 are rollingly connected between the annular groove 711 and the movable ring 73. The inner diameter of the through hole 41 and the inner diameter of the fixed ring 71 are both larger than the outer diameter of the positioning shaft 72; in this embodiment, during the process that the pressing cylinder component 6 drives the press-fitting seat 5 to move the pressing table 4 downward and the positioning column 9 is gradually inserted into the positioning hole, by the rolling connection of the plurality of positioning steel balls 74 between the annular groove 711 and the movable ring 73, the positioning shaft 72 can move back and forth and left and right in the through hole 41, finely adjusting the position of the pressing table 4, making it easier for the round head 91 at the bottom end of the positioning column 9 to insert into the control board, and at the same time, initially positioning the control board.

[0030] like Figure 1-7 As shown, L-shaped clamping plates 111 are respectively provided on the left and right sides of the pressing platform 4, and side clamping cylinders 112 are symmetrically provided on the left and right sides of the pressing platform 4. The piston rod heads of the side clamping cylinders 112 extend horizontally to drive the vertical parts connected to the L-shaped clamping plates 111; in this embodiment, the automatic loading robot loads the control plate onto the upper pallet, the pressing cylinder assembly 6 drives the press-fitting seat 5 to drive the pressing platform 4 to move downward, and after the suction cup 8 sucks the control plate, the piston rod heads of the side clamping cylinders 112 retract horizontally, and clamp the left and right sides of the control plate through the vertical parts of the L-shaped clamping plates 111.

[0031] like Figure 1-7 As shown, the pressure cylinder assembly 6 includes a frame 61 vertically fixed on the workbench 1, a slide rail 62 vertically arranged on the front of the frame 61, a slide 63 slidably connected to the slide rail 62, a servo electric cylinder 1 64 fixed on the top of the slide rail 62, and a servo electric cylinder 2 65 fixed on the slide 63. The piston rod head of the servo electric cylinder 2 65 extends vertically downward to drive the press seat 5. In this embodiment, the servo electric cylinder 1 64 drives the slide 63 to slide up and down along the slide rail 62, and the servo electric cylinder 2 65 drives the press seat 5 to rise or fall, so that the press seat 5 and the press table 4 rise or fall.
