[0002] The flip docking machine is a device used to test memory chips. During the test, the test head needs to be flipped from horizontal to vertical, and then fit with the pins of the memory chips on the test sorting machine for testing. In this process, the flip docking mechanism needs to rely on manual shaking of the gears to drive the test head, which is time-consuming and laborious.

The control box 2 is fixedly connected to the side of the base 1. The support plate 11 is used to support the test head 3 and is rotatably connected to the test head 3. A moving device 44 is provided between the support plate 11 and the base 1 to enable the test head 3 and the support plate 11 to slide back and forth. The moving device 44 is provided with a flipping device 4 that can flip the test head 3 from a horizontal direction to a vertical direction.

[0026] The moving device 44 includes a slider 441 , a lead screw 442 , a bevel gear set 443 and a hand wheel 444 .

[0027] The slider 441 is connected to the base 1 through a slide rail and a slide groove. A lead screw 442 is horizontally arranged on the slider 441. The sliding directions of the lead screw 442 and the test head 3 are parallel to each other. Both ends of the lead screw 442 are supported on the base 1 through a support seat 445. One end of the lead screw 442 is connected to a bevel gear set 443. The bevel gear set 443 includes a driving bevel gear 4431 and a driven bevel gear 4432. The driven bevel gear 4432 is coaxially connected to the lead screw 442. The driving bevel gear 4431 is connected to a handwheel 444. The driving bevel gear 4431 and the driven bevel gear 4432 are meshed with each other.

[0028] When it is necessary to slide forward and backward, the hand wheel 444 is rotated to drive the bevel gear set 443, which transmits power to rotate the lead screw 442, thereby driving the slider 441 to slide forward and backward on the base 1, thereby realizing the forward and backward sliding of the test head 3 and the flip device 4.

[0029] The test head 3 is square in shape as a whole, and a plurality of test pins for detecting parts are arranged on a side facing the base 1 . Support rods 31 are fixed on both sides of the test head 3 , and the support rods 31 are rotatably connected to the support plate 11 .

[0030] like Figure 1 As shown, the flip device 4 includes a driving assembly 41, a transmission assembly 42 and a connecting member 43. The connecting member 43 is fixed on the test head 3. The connecting member 43 is provided with a waist-shaped groove 431. The waist-shaped groove 431 is rotatably connected to the transmission assembly 42.

[0032] The driving assembly 41 includes a motor 411 and a worm gear assembly 412 . The motor 411 is coaxially connected to the worm 4122 . The worm gear 4121 and the worm 4122 are meshed with each other to transmit power. The worm gear 4121 is coaxially fixedly connected to the threaded barrel 422 .

[0033] The worm gear assembly 412 is fixed on the base 1 via a support seat.

[0034] The flipping device 4 is provided with two groups, which are respectively located on the left and right sides of the test head 3. The two worm gears 4122 are connected by a connecting rod 5 to achieve synchronous rotation.

[0035] The test head 3 is also provided with a locking assembly 6, which includes a locking hole 61, a cylinder 62 and a sensor 63. The locking hole 61 is located on the test head 3. When the test head 3 is vertical, the cylinder 62 is arranged opposite to the locking hole 61. The sensor 63 is located inside the locking hole 61 and on the output rod of the cylinder 62. When the test head 3 is rotated to be vertical, the sensors 63 sense each other, the cylinder 62 works, and the cylinder rod of the cylinder 62 is inserted into the locking hole 61, so that the test head 3 is locked and immovable.

[0036] When working, the controller controls the motor 411 to start, the worm wheel 4121 and the worm 4122 rotate, driving the threaded barrel 422 to rotate, so that the threaded rod 421 extends outward, pushes the connecting piece 43, and rotates the connecting piece 43 90 degrees, so that the test head 3 rotates from the horizontal direction to the vertical direction. The cylinder is aligned with the locking hole, the sensor transmits a signal, and the cylinder rod is inserted into the locking hole to lock the test head 3.

[0037] The hand wheel 444 is shaken to rotate the spur gear set, so that the lead screw 442 drives the slider 441 to slide, so that the test head 3 and the flip assembly slide on the base 1 to the specified position, with one side of the test needle facing the test sorting machine, so that the test head 3 is connected to the test sorting machine.
