Now the functions of cars are becoming more and more powerful, so there are more and more switches on cars. At the same time, due to the advantages of small size and light weight of touch switches, touch switches are widely used in cars, such as car audio switches, car multimedia player switches, etc.

[0003] The quality of automobile switches is related to the quality of the entire vehicle. In order to improve the quality of the automobile, the switch qualification rate needs to be tested. However, the existing testing equipment is troublesome to locate during testing, and cannot quickly load and unload materials and connect the switch to the circuit, resulting in low testing efficiency. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an automatic testing station for comprehensive performance of automobile control switches, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic testing platform for comprehensive performance of automobile control switches, including a frame and a loading platform and an unloading platform respectively fixed on the sides of the frame, the surface of the frame is rotatably connected with a work station disk, the surface of the work station disk is provided with a plurality of work stations arranged in an annular array, the loading platform loads the switch to the loading station through a loading robot, the work station includes a fixed frame fixed to the surface of the work station disk, the side of the fixed frame is fixedly connected with a limit frame for limiting the switch, the surface of the limit frame is slidably connected with a sliding block, the bottom of the sliding block is respectively fixedly connected with a reset spring and an elastic airbag, the bottom of the reset spring and the elastic airbag are fixedly connected to the top of the fixed frame, and the inner cavity of the fixed frame is opened A conductive slot is built in for plugging in switch cells, a pushing airbag is fixedly connected to the inner cavity of the conductive slot, a conductive clamp electrically connected to the switch cell is fixedly connected to one side of the pushing airbag, a pushing spring is fixedly connected to one end of the pushing spring and the inner cavity of the conductive slot, the inner cavity of the elastic airbag is connected to the inner cavity of the pushing airbag through a connecting pipe, an arc-shaped top frame located above the workstation of the workstation disk is fixedly connected to the surface of the frame, a slope gradually rising from left to right is provided on the left side of the arc-shaped top frame, a driving cylinder is fixedly connected to the surface of the arc-shaped top frame, one end of the driving cylinder piston rod passes through and extends to the bottom of the arc-shaped top frame, and a detection rod is fixedly connected to the end of the driving cylinder piston rod. At this time, the switch is placed from the loading table to the fixed frame on the workstation through the loading robot. At this time, the switch is placed on the surface of the sliding block, and the two sides are covered by the top of the sliding block. Then the workstation disk rotates counterclockwise to drive the workstation to continue moving. The workstation moves to the arc-shaped top frame. At this time, the switch rotates, and the upper part is gradually squeezed by the arc-shaped top frame, compressing the reset spring to move downward, driving the sliding block to slide downward on the surface of the limit frame. At this time, the battery cell of the switch is inserted into the conductive groove. At this time, the elastic airbag is squeezed, and the internal gas enters the pushing airbag from the connecting pipe. The pushing airbag pushes the two conductive clamps to move in the direction of the switch battery cell to close, clamp the switch battery cell, and conduct electricity. Then the workstation disk drives the workstation to continue rotating, and the loading is continuously carried out. The workstation rotates to the bottom of the driving cylinder The detection rod below the drive cylinder is lowered to press the switch, and the signal is detected by the built-in detection component of the frame to see if it is normal.

[0008] As a further solution of the present invention: a discharging guide frame is fixedly connected to one side of the frame, the discharging guide frame is two guide rails, and the right end of the discharging guide frame is provided with an arc-shaped protrusion which gradually rises from left to right, the right end of the discharging guide frame is an arc shape adapted to the rotation trajectory of the switch, and the left end of the discharging guide frame is a straight rail.

[0009] As a further solution of the present invention: the right side of the discharging guide frame is located below the switch, and the linear track at the left end of the discharging guide frame is located above the workstation.

[0010] As a further solution of the present invention: the arc-shaped top frame is arranged above the 90-210 degree workstation, and a ball is rotatably connected to the top of the switch for rolling connection below. The three workstations are measured sequentially with high accuracy, and the ball makes the movement of the workstation smoother.

[0012] 1. The present invention can quickly load and unload switches and conduct electrical connection detection, automatically position switches, and ensure effective detection effects. It can adapt to the plugging of cells of switches of different sizes, thereby greatly improving processing efficiency.

[0013] 2. In the present invention, the work station moves to the arc-shaped top frame. At this time, when the switch rotates, the upper part is gradually squeezed by the arc-shaped top frame, and the reset spring is compressed downward to move, driving the sliding block to slide downward on the surface of the limit frame. At this time, the battery cell of the switch is inserted into the conductive groove. At this time, the elastic airbag is squeezed, and the internal gas enters the pushing airbag from the connecting pipe. The pushing airbag pushes the two conductive clamps to move toward the direction of the switch battery cell to close, clamp the switch battery cell, and conduct electricity.

[0014] 3. In the present invention, the work station disc drives the work station to rotate to the outside of the arc-shaped top frame.
