[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings. Typical embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0027] refer to Figure 1-3 The carrier rotation and transfer device of the present invention includes a turntable 1, a lifting and rotating mechanism 2, a carrier automatic clamping device 3, and a downward limiting device (not shown in the figure, specifically a limiting block).

[0028] The turntable 1 is a horizontally arranged circular disc. The lifting and rotating mechanism 2 is connected to the center position of the circle at the bottom of the turntable, and is used to drive the turntable 1 to lift and lower and to drive the turntable 1 to rotate around the center of the turntable 1. The lifting and rotating mechanism includes a motor 21, an induction wheel 22, a sensor 23, a lifting divider 24, etc. The induction wheel 22 and the sensor 23 are used to detect the zero lowest position of the turntable 1, and the motor 21 is the power source of the entire lifting and rotating mechanism. The lifting divider is a high-precision motion control device that can achieve accurate lifting and indexing motion. The lifting divider 24 is connected to the bottom of the turntable 1, and the lifting divider 24 is used to drive the turntable 1 to lift and rotate.

[0029] A plurality of workstations are arranged in the rotation path of the turntable 1, and the plurality of workstations are arranged in a circle in sequence along the rotation direction of the turntable. The turntable 1 rotates to carry the magnetic head of the hard disk under test and switches in sequence between the plurality of workstations. In this embodiment, the test items to be performed as needed mainly include a loading station, a plurality of operating stations, and an unloading station distributed in sequence along the rotation direction of the turntable 1. These stations are arranged in a circle and evenly spaced along the edge of the turntable 1. During the test process, these stations can synchronously perform corresponding functions. For example, when the loading station is loading, the unloading station is unloading synchronously, and the operating station 1 and the operating station 2 are performing their respective corresponding test contents. Figure 1Only two operating stations are shown. It can be understood that the number of operating stations and their functions can actually be set according to the content of the test items. This embodiment is only a schematic and is not intended to limit the present invention.

[0030] The carrier automatic clamping device 3 is installed on the turntable 1 and is used to automatically clamp the carrier 4. The carrier 4 is used to position and place the product to be tested with its front side facing up. A plurality of the carrier automatic clamping devices 3 are installed on the turntable 1 in a circle evenly spaced apart along the periphery of the turntable 1, and are switched in sequence between the plurality of workstations as the turntable 1 rotates, that is, the carrier 4 will switch between the various workstations as the turntable 1 rotates. In the present utility model, the number of carrier automatic clamping devices 3 and carriers 4 is consistent with the number of workstations, ensuring that at any time, each workstation position corresponds to a carrier automatic clamping device 3 and a carrier 4. This article defines the angle that the turntable 1 needs to rotate when the carrier automatic clamping device 3 and carrier 4 switch from one workstation to the next as a rotation step, and the step is equal to 360° / M, where M is the number of workstations. For example, in this embodiment, the number of workstations is four, and the rotation step of the turntable 1 is 90°.

[0031] The downward limit device is used to cooperate with the automatic clamping device 3 of the carrier to realize the lifting and opening of the automatic clamping device 3 of the carrier. The number of the downward limit devices is consistent with the number of the automatic clamping devices 3 of the carrier, and the multiple downward limit devices are fixedly installed in a circle in the space below the turntable 1, specifically at the position of each workstation. When the turntable 1 rotates until the automatic clamping device 3 of the carrier reaches directly above the downward limit device or reaches the workstation, the turntable 1 will first descend, and the automatic clamping device 3 of the carrier will hit the downward limit device during the descent process and be forced to open so that the carrier 4 can be taken out. After each workstation performs the corresponding function, the turntable 1 will rise with the automatic clamping device 3 of the carrier to automatically clamp the carrier, and then the turntable 1 will rotate to the next workstation.

[0032] refer to Figure 4 , the carrier automatic clamping device 3 includes an elastic member 31, a carrier pressure block 32, a carrier guide block 33, a top block 34, a guide column 35, etc. The elastic member 31 is specifically a spring. The number of the top blocks 34 is consistent with that of the carrier pressure block 32, and the number of the elastic members 31 and the guide columns 35 depends on the situation. In this embodiment, each carrier pressure block 32 is configured with two guide columns 35 and one elastic member 31. The carrier pressure block 32 can move in the vertical direction to press the carrier 4. The carrier guide block 33 is used to guide the carrier 4 to be placed and position the carrier 4. After the carrier 4 is placed in the carrier guide block 33, the bottom and four sides of the carrier are limited by the carrier guide block 33, and the top is pressed and limited by the carrier pressure block 32. The elastic member 31 is used to control the default state of the carrier pressure block 32 to be pressed down, and the top block 34 is used to cooperate with the downward limiting device to limit the moving stroke of the carrier pressure block 32, so that the carrier pressure block 32 is forced to be lifted up and opened.

[0033] In this embodiment, the side of the carrier guide block 33 is open for the carrier 4 to be pushed in / out horizontally along the radial direction of the turntable 1. The top block 34 is located below the turntable, and the guide column 35 moves through the turntable 1. The two ends of the carrier pressure block 32 are connected to the two ends of the corresponding top block 34 through the two corresponding guide columns 35. The elastic member 31 is connected to the carrier pressure block 32 and provides elastic force in the vertical direction. The elastic force of the elastic member 31 acts on the top block 34. In the free state, the elastic force of the elastic member 31 presses the top block 34 downward, thereby moving the carrier pressure block 32 downward through the guide column 35 to press the carrier 4 located in the carrier guide block 33.

[0034] The downward limiting device presses against the push block 34 during the descent of the turntable 1, thereby lifting the carrier pressing block 32 and causing it to move upward to the lifted position, overcoming the elastic force of the elastic member 31. This facilitates the horizontal insertion and removal of the carrier 4 from the carrier guide block 33. After the turntable 1 ascends and the carrier pressing block 32 is released from the downward limiting device, the elastic member 31 drives the carrier pressing block 32 to the downward pressed position based on its elastic force, thereby firmly pressing the carrier 4 in the carrier guide block 33.

[0035] Preferably, the carrier automatic clamping device 3 further includes a linear bearing 36 corresponding to the guide column 35 . The linear bearing 36 is fixedly mounted on the corresponding carrier guide block 33 , and the guide column 35 passes through the linear bearing 36 .

[0036] Specifically, the edge of the turntable 1 is provided with a plurality of notches 11 corresponding to the plurality of carrier automatic clamping devices 3. The carrier guide block 33 includes a carrier accommodating groove portion 332 and a flange fixing portion 331. The carrier accommodating groove portion 332 is inserted into the notch 11, and the flange fixing portion 331 is hung on the turntable 1 and locked to the turntable 1 via a locking member. The carrier accommodating groove portion 332 is used to perform slot-type positioning on the horizontally placed carrier 4. The side of the carrier accommodating groove portion 332 facing the radial direction of the turntable is open to facilitate horizontal insertion / extraction of the carrier 4. The top of the carrier accommodating groove portion 332 is open, and the top edge extends horizontally outward to form the flange fixing portion 331. The carrier pressure block 32 is disposed on the flange fixing portion 331 and extends into the carrier accommodating groove portion 332.

[0037] Specifically, the carrier pressing block 32 includes a pressing portion 322 and a connecting portion 321 that are vertically connected to each other to form an "L"-shaped structure. The pressing portion 322 and the connecting portion 321 can be integrally formed or connected together by a connecting piece. The bottom of the carrier accommodating groove portion 332 includes two bearing portions 3321 that are arranged opposite each other and spaced apart in the circumferential direction of the turntable 1 for supporting the carrier 4. A space is left between the two bearing portions 3321 to avoid a carrier transplanting device for transplanting the carrier 4 (the carrier transplanting device is mainly a translation cylinder structure on the workstation). There are two carrier pressing blocks 32, which are arranged opposite each other and spaced apart in the circumferential direction of the turntable 1 on the flange fixing portion 331. The pressing portions 322 of the two carrier pressing blocks 32 also extend above the two bearing portions 3321 respectively. The connecting portion 321 of each carrier pressing block 32 is placed horizontally on one of the flange fixing portions 331, and the pressing portion 322 extends into the carrier accommodating groove 332 and is located above the bearing portion 3321. The pressing portion 322 and the bearing portion 332 together clamp the carrier 4 up and down. The linear bearing 36 is fixed on the flange fixing portion 331. Figure 4 The figure specifically illustrates two states of the carrier pressing block 32. The carrier pressing block 32 on the left is in a depressed state, so the linear bearing 36 cannot be seen. The carrier pressing block 32 on the right is in an open state, so the linear bearing 36 can be seen. The guide post 35 passes through the turntable 1 and the corresponding linear bearing 36 and then connects to the corresponding connecting portion 321. The elastic member 31 is abutted between the top block 34 and the turntable 1. In other embodiments, the elastic members 31 can be the same number as the guide posts 35 and can be sleeved outside the guide posts 35.

[0038] refer to Figure 5 , Figure 5 From a bottom-up perspective, the carrier 4 is roughly rectangular, positioned with the front side facing upward to hold the hard drive head under test. The bottom of the carrier 4 is provided with two diagonally spaced transfer positioning holes 41 and two diagonally spaced workstation positioning holes 42. Correspondingly, two carrier transfer positioning pins 3322 protrude from the upper surfaces of the two supporting portions 3321 at the bottom of the carrier accommodating slot 332 of the carrier guide block 33, respectively, for engagement with the two transfer positioning holes 41.

[0039] In this embodiment, each station operates in parallel, allowing loading, unloading, and other operations to proceed simultaneously. Each time turntable 1 rotates one step, the product moves from one station to the next. Turntable 1 then begins to descend, and once it reaches its designated position, each station begins its corresponding operation. After each station completes its operation, turntable 1 ascends, and once it reaches its designated position, it begins rotating. Once it reaches one step, the product moves to the next station, and this cycle repeats.

[0040] Specifically: (1) When the turntable 1 rotates, the lifting divider 24 is in the upper position. After one step of rotation, the lifting divider 24 is in the upper position, and the automatic clamping devices 3 of each carrier on the turntable 1 are exactly in the respective workstation positions; (2) Then, the lifting divider 24 descends, and the lower downward limit device contacts the top block 34. The top block 34 cannot continue to descend, and the carrier pressure block 32 cannot continue to move downward. The spring is compressed, and the carrier guide block 33 continues to descend with the turntable. Therefore, when the lifting divider 24 descends to the lower position, the carrier pressure block 32 moves upward relative to the carrier guide block 33. For the unloading station and the operating stations 1 and 2, this is equivalent to loosening the carrier 4. At this time, the station positioning hole 42 of the carrier 4 enters the positioning pin on the station, and the translation cylinder brings the carrier 4 out of the side of the carrier guide block 33 and out of the carrier automatic clamping device 3 for unloading or performing related test operations. For the loading station, the translation cylinder brings the carrier 4 from the side of the carrier guide block 33 into the carrier guide block 33 to realize loading; (3) Then, after all the station operations are completed, the lifting divider 24 rises, the turntable 1 rises, the top block 34 disengages from the downward limit device, and the spring pushes the top block 34 downward, thereby moving the carrier pressure block 32 downward to press the carrier 4. When the lifting divider 24 is in the upper position and rises to the upper position, the transfer positioning hole 41 of the carrier 4 is inserted into the transfer positioning pin 3322, and finally the four sides of the carrier 4 are positioned by the carrier guide block 33 in a groove-type manner. The carrier 4 is clamped up and down by the carrier pressure block 32 and the carrier guide block 33 at the same time; (4) Then the turntable 1 rotates to the next step. In this way, it reciprocates according to (1)-(4).

[0041] In summary, the utility model can transfer carriers in multiple stations and processes, and the layout can be miniaturized; the carrier enters from the side, and the lifting divider automatically positions the carrier when it is raised and lowered. The carrier can be automatically opened under the limiting action of the downward limiting device, and the spring action and the surrounding guiding and positioning action of the carrier guide block enable the carrier to maintain a stable state during rotational transfer.
