[0041] The embodiment of the present application provides a lifting buffer workbench, please refer to Figures 1 to 3 The lifting buffer workbench includes a base 1, a slide rail 2, a slider 3, a lifting platform 4 and a through-type lead screw stepper motor 5. The slide rail 2 is arranged on the base 1 and extends in the vertical direction. The slider 3 is slidably arranged on the slide rail 2. The lifting platform 4 is arranged on the slider 3. The through-type lead screw stepper motor 5 is arranged on the base 1. The through-type lead screw stepper motor 5 includes a lead screw 510 that performs linear motion in the vertical direction. The lead screw 510 is connected to the lifting platform 4.

[0042] In the embodiment of the present application, the lifting buffer workbench includes a base 1, a slide rail 2, a slider 3, a lifting platform 4 and a through-type screw stepper motor 5. The lifting platform 4 is driven to rise and fall by the through-type screw stepper motor 5 installed on the base 1. Compared with the cylinder-driven lifting, the through-type screw stepper motor 5 has a smaller sudden change in start and stop speed, and the inertial impact on the product is smaller. The product on the lifting platform 4 is not easy to shift or deform and be damaged, thereby improving the production quality of the product.

[0043] In one embodiment, please refer to Figure 1 and Figure 2 There are two slide rails 2, which are arranged at opposite ends of the base 1, and there are two sliders 3 corresponding to the slide rails 2, which are arranged at opposite ends of the lifting platform 4, so that the lifting platform 4 can be lifted and lowered stably and evenly.

[0044] In one embodiment, please refer to Figure 2 and Figure 3 A first avoidance hole 411 and a second avoidance hole connected together are sequentially arranged on the lifting platform 4 from top to bottom. The aperture of the first avoidance hole 411 is larger than that of the second avoidance hole. The screw rod 510 can be movably inserted in the second avoidance hole. A screw 6 is threaded on the end face of the screw rod 510, and the nut of the screw 6 only moves in the first avoidance hole 411. An annular rib 511 is arranged on the side circumference of the screw rod 510 below the lifting platform 4, and an elastic member 7 is squeezed and clamped between the annular rib 511 and the lifting platform 4.

[0045] In this way, the lifting platform 4 absorbs energy through buffering through the elastic member 7 , thereby further improving the stability of the movement of the lifting platform 4 .

[0046] Specifically, when the lifting platform 4 needs to rise, the screw 510 of the through-type screw stepper motor 5 rises, and the elastic member 7 is subjected to an upward pressure, pushing the lifting platform 4 to rise with acceleration; until the pressure on the elastic member 7 accumulates to a certain extent, the lifting platform 4 is balanced and rises with uniform speed; when the lifting platform 4 is about to reach the specified position, the screw 510 no longer applies pressure to the elastic member 7, so that the force balance of the lifting platform 4 is broken, and at this time, the lifting platform 4 rises with deceleration until the rising speed is zero, completing the rise of the lifting platform 4. When the lifting platform 4 needs to descend, the screw 510 of the through-type screw stepper motor 5 descends, and the screw 6 on the screw 510 drives the lifting platform 4 to descend together.

[0047] In one embodiment, please refer to Figure 2 and Figure 3The lifting platform 4 includes a main platform 410 and a guide block 420, a first avoidance hole 411 is arranged on the main platform 410, the guide block 420 is arranged at the bottom of the main platform 410 and covers the first avoidance hole 411, and a second avoidance hole is arranged on the guide block 420. The guide block 420 is used to guide the screw rod 510 to move up and down.

[0048] In one embodiment, the elastic member 7 is a spring.

[0049] In one embodiment, see Figure 2 The through-type lead screw stepper motor 5 is arranged at the center of the base 1 so that the base 1 is evenly stressed. A third avoidance hole 110 for avoiding the lead screw 510 is provided on the base 1 to ensure that the up and down movement of the lead screw 510 will not be interfered.

[0050] In one embodiment, see Figure 2 The through-type lead screw stepper motor 5 also includes a main body 520, both ends of the lead screw 510 protrude from the main body 520, a first limit block 530 for limiting the lowest moving position of the lead screw 510 is provided on the lead screw 510 above the main body 520, and a second limit block 540 for limiting the highest moving position of the lead screw 510 is provided on the lead screw 510 below the main body 520.

[0051] In one embodiment, the first limit block 530 is made of elastic material, and the first limit block 530 can play a role in buffering and absorbing energy to reduce the inertial impact on the product during the descent of the lifting platform 4.

[0052] In one embodiment, please refer to Figure 1 and Figure 2 The lifting buffer workbench also includes a clamping structure 8, which includes a fixed rib 810, a rotating rib 820 and a driving member 830. The fixed rib 810 is arranged at one end of the top surface of the lifting platform 4, and the rotating rib 820 is rotatably arranged at the other end of the top surface of the lifting platform 4. During the rotation of the rotating rib 820, the product on the lifting platform 4 is clamped between the rotating rib 820 and the fixed rib 810, and the driving member 830 is used to drive the rotating rib 820 to rotate.

[0053] Furthermore, the rotating rib 820 is a bending plate, and the driving member 830 is a cylinder. The cylinder is rotatably mounted on the slider 3 on the side of the lifting platform 4, and the moving end of the cylinder is rotatably connected to one side of the rotating rib 820. The cylinder can drive the rotating rib 820 to rotate so that the rotating rib 820 is close to or away from the fixed rib 810, thereby achieving the clamping and loosening of the product.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
