[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Example

[0030] Reference Figure 1-3 As shown, a horizontal alternating feeding device of this utility model includes:

[0031] Frame 1;

[0032] The first support mechanism 8 includes: a first drive member 23 and a first fixture assembly 5. The first drive member 23 is disposed on the frame 1, and the first fixture assembly 5 is connected to the output end of the first drive member 23.

[0033] The second support mechanism 7 includes: a second drive component 20, a lifting component, and a second fixture component 6. The second drive component 20 is disposed on the frame 1. The lifting component is connected to the output end of the second drive component 20. The second fixture component 6 is connected to the output end of the lifting component. The first fixture component 5 and the frame 1 enclose a receiving space. The second fixture component 6 can be received into the receiving space.

[0034] The present invention discloses a horizontal alternating feeding device. A product to be tested is placed on a first fixture assembly 5. A first driving component 23 moves the first fixture assembly 5 towards the testing station, allowing the product to be tested. Another product to be tested is placed on a second fixture assembly 6. A second driving component 20 moves the second fixture assembly 6 below the first fixture. After testing of the product on the first fixture assembly 5, the first driving component 23 moves the first fixture assembly 5 back to allow for the placement of the next product to be tested. Simultaneously, a lifting component raises the second fixture assembly 6, raising another product to the testing station for testing. After testing of the product on the second fixture assembly 6, the lifting component and the second driving component 20 reverse their directions to allow for the placement of the next product to be tested on the second driving component 20. This allows for continuous testing without waiting for placement and horizontal transport of products after testing, optimizing the work cycle and improving testing efficiency.

[0035] The frame 1 includes: a base plate 21 and side plates 22 respectively connected to both sides of the base plate 21. The first driving member 23 and the second driving member 20 are respectively disposed on the side plates 22 and the base plate 21. The base plate 21 serves as the bottom support platform of the device, used to install the second driving member 20 and bear the weight of the entire device, and together with the side plates 22, it encloses the bottom boundary of the accommodating space.

[0036] Reference Figure 4As shown, the lifting assembly includes: a bracket 9, a third drive component 10, a lifting screw 15, a first nut seat 18, and a lifting platform 16. The bracket 9 is located at the output end of the second drive component 20, the third drive component 10 is located on the bracket 9, the lifting screw 15 is connected to the output end of the third drive component 10, the first nut seat 18 is fitted onto the lifting screw 15, and the lifting platform 16 is connected to the first nut seat 18. The bracket 9 is the basic load-bearing structure of the lifting assembly, used to install the third drive component 10, the lifting screw 15, and support the movement of the lifting platform 16. The third drive component 10 is the power source for the lifting action, using a servo motor. The lifting screw 15 and the first nut seat 18 form a screw-nut pair, thereby achieving vertical lifting. The first nut seat 18 is fitted onto the outside of the lifting screw 15 and threadedly engages with the screw. When the screw rotates, the nut seat moves linearly along the screw axis, driving the lifting platform 16 to rise and fall. The lifting platform 16 is the direct load-bearing component of the second fixture assembly 6.

[0037] Reference Figure 3 As shown, the output shaft of the third drive unit 10 is connected to a first steering gear 11. The first steering gear 11 is connected to at least two first transmission shafts 12, and each of the at least two first transmission shafts 12 is connected to a second steering gear 13. The third drive unit 10 is a servo motor, mounted on the bracket 9, and its output shaft is directly connected to the first steering gear 11. The first steering gear 11 has multiple output ends, such as bevel gear steering gears, which can redirect the rotational power output by the third drive unit 10 and distribute the power to at least two first transmission shafts 12. The first transmission shafts 12 are rigid shafts with certain strength and rigidity, and can effectively transmit torque. One end of the first transmission shaft 12 is connected to the output end of the first steering gear 11, and the other end is connected to the second steering gear 13. The second steering gear 13 can also be a bevel gear steering gear, which redirects the power transmitted from the first transmission shafts 12 again to drive the lifting screw 15 connected to the second steering gear 13 to rotate. The arrangement of at least two first transmission shafts 12 allows the power to be distributed to different positions to drive multiple lifting screws 15 to rotate synchronously. The synchronous operation of multiple lifting screws 15 can ensure the stability of the lifting platform 16 during the lifting process, avoiding tilting or shaking, thereby ensuring that the second fixture assembly 6 can accurately rise to the test position or descend to the appropriate position.

[0038] Reference Figure 4As shown, the support 9 is equipped with a stop frame 26. The height of the top surface of the stop frame 26 relative to the support 9 is greater than the height of the end of the lifting screw 15 relative to the support 9. The end of the lifting screw 15 is rotatably connected to the stop frame 26. Since the height of the top surface of the stop frame 26 is higher than the end of the lifting screw 15, the stop frame 26 can limit the movement of the first nut seat 18 and the lifting platform 16 during the process of the lifting screw 15 driving the first nut seat 18 and related components to rise.

[0039] The lifting platform 16 is connected to a support rod 19, which extends from the lifting platform 16 away from the bracket 9. The second fixture assembly 6 is connected to the end of the support rod 19. The maximum stroke of the second fixture assembly 6 is increased so that the height of the second fixture assembly 6 is consistent with that of the first fixture assembly 5.

[0040] The second steering mechanism 13 is connected to at least one lifting lead screw 15 and a second drive shaft 30. The second drive shaft 30 is connected to a third steering mechanism 14, which is also connected to at least one lifting lead screw 15. Upon receiving power, the second steering mechanism 13 directly drives the at least one lifting lead screw 15 connected to it to rotate. The rotation of the lifting lead screw 15 causes the first nut seat 18, which it engages with, to move linearly along the lead screw, providing a portion of the lifting driving force for the lifting platform 16. Simultaneously, the second steering mechanism 13 transmits another portion of the power to the third steering mechanism 14 via the second drive shaft 30. Upon receiving power, the third steering mechanism 14 drives the at least one lifting lead screw 15 connected to it to rotate, causing the corresponding first nut seat 18 to move linearly along these lifting lead screws 15, providing another portion of the lifting driving force for the lifting platform 16. Multiple lifting lead screws 15 rotate synchronously or collaboratively under the drive of the second steering mechanism 13 and the third steering mechanism 14, ensuring that the lifting platform 16 connected to the first nut seat 18 receives a uniform driving force at multiple points, thus smoothly rising or falling.

[0041] The first fixture assembly 5 and the stop bracket 26 have a gap in the height direction. The first fixture assembly 5 and the second fixture assembly 6 have the same structure and are used to place the product to be tested, which will not be described in detail in this embodiment.

[0042] Reference Figure 5 , Figure 6 As shown, both the first driving component 23 and the second driving component 20 include: a driving motor 27, a movable lead screw 29, and a second nut seat 28. The movable lead screw 29 is connected to the output end of the driving motor 27, and the second nut seat 28 is fitted and adapted to the movable lead screw 29. The driving motor 27 drives the corresponding movable lead screw 29 to rotate, and the second nut seat 28 and the movable lead screw 29 cooperate to achieve linear movement. The second nut seat 28 drives the corresponding bracket 9 and the first fixture assembly 5 to move.

[0043] A first sliding pair 24 is provided between the first support mechanism 8 and the side plate 22, and a second sliding pair 25 is provided between the second support mechanism 7 and the base plate 21. This provides low-friction, high-precision, and stable guidance for the movement of the first support mechanism 8 and the second support mechanism 7. By setting the sliding pair, the resistance of the support mechanism during movement can be reduced, energy loss can be decreased, and the support mechanism can be ensured to move linearly along a predetermined trajectory, improving the movement accuracy and stability of the device, while preventing the lead screw mechanism from causing rotation of the corresponding nut seat.

[0044] Reference Figure 1 As shown, the device also includes a base 2, which is equipped with multiple foot cups and air-float support components 3. The frame 1 is connected to the ends of the foot cups and air-float support components 3. A pressure sensor 4 is also installed between the base 2 and the frame 1. During installation, the base 2 is placed on the working surface. The height and level of the device are initially adjusted by rotating the adjusting nuts of the foot cups to make the device roughly level. Then, the air supply system is started, and compressed air is introduced into the air-float pad of the air-float support component 3. The air pressure in the air-float pad gradually increases, forming an air film that smoothly supports the frame 1, achieving non-contact support between the frame 1 and the base 2, reducing vibration and friction. During operation, the pressure sensor 4 monitors the pressure changes between the base 2 and the frame 1 in real time. When the first support mechanism 8 and the second support mechanism 7 move horizontally or lift vertically, the center of gravity of the device changes, causing the pressure distribution at each support point to change accordingly. The pressure sensor 4 transmits these pressure change data to the control system in real time. The control system analyzes and processes the pressure data according to the preset pressure threshold and algorithm. If an abnormal pressure change is detected, it indicates that the device has an unbalanced load, component failure, or other problems. The control system will issue an alarm in a timely manner and take corresponding measures, such as adjusting drive parameters or stopping the device, to ensure the safe and stable operation of the device.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
