Description

Technical Field

[0001] This utility model belongs to the technical field of automated material conveying equipment, specifically relating to the upper and lower level mechanism of an elevator. Background Technology

[0002] In the field of electronic component testing, the aging test of BIB (Burn-in-Board) requires the sequential feeding of multi-layer stacked test boards into the test module. Traditional testing equipment often uses a single-layer lifting mechanism combined with manual loading and unloading. This structure is not only inefficient, but also difficult to meet the requirements of modern production lines for automation and testing efficiency. With the continuous improvement of testing needs, it is particularly important to develop an automated lifting mechanism with multi-layer synchronous loading and unloading functions.

[0003] The existing lifting mechanism can only operate on a single layer and cannot achieve synchronous loading and unloading between upper and lower layers, resulting in low testing efficiency. The positioning accuracy of the loading and unloading mechanism is insufficient, which can easily cause damage to the BIB board. The control system is complex and requires separate programming for different layer heights, which increases the difficulty of debugging and maintenance costs. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides an upper and lower level mechanism for an elevator, including,

[0026] The loading mechanism 100 includes a base frame 101, a support frame 102 fixedly installed on the side wall of the base frame 101, a support bar 103 fixedly installed on the inner wall of the support frame 102, and a fixing bar 104 fixedly installed on the side wall of the support bar 103.

[0027] The feeding mechanism 200 includes a limiting rod 202 fixedly installed on the side wall of the base plate 201, a rack 203 fixedly installed on the side wall of the base plate 201, a lifting assembly 204 disposed on the surface of the limiting rod 202, an installation assembly 205 disposed in the inner cavity of the lifting assembly 204, and a feeding assembly 206 disposed in the inner cavity of the installation assembly 205.

[0028] Specifically, the lifting assembly 204 includes a movable housing 204a slidably connected to the surface of the limiting rod 202, a movable motor 204b adapted to be installed on the inner wall of the movable housing 204a, and a gear 204c fixedly installed on the output end of the movable motor 204b. The lifting assembly 204 also includes a lifting motor 204d adapted to be installed on the inner wall of the movable housing 204a, a drive wheel 204e connected to the output end of the lifting motor 204d via a belt 205e, and a lead screw fixedly installed on the side wall of the drive wheel 204e.

[0029] Among them, gear 204c meshes with rack 203. When the moving motor 204b starts, it will drive gear 204c to rotate. Gear 204c, in conjunction with rack 203, will drive moving shell 204a to move along the direction of limit rod 202.

[0030] The mounting assembly 205 includes a connecting seat 205a fixedly mounted on the inner wall of the movable housing 204a, a mounting plate 205b fixedly mounted on the side wall of the connecting seat 205a, and a translation motor 205c adapted to be mounted on the side wall of the mounting plate 205b. The mounting assembly 205 also includes a fixed pulley 205d fixedly connected to the bottom of the mounting plate 205b, a belt 205e sleeved on the output end of the translation motor 205c and the outer surface of the fixed pulley 205d, and a movable plate 205f fixedly connected to the side wall of the belt 205e.

[0031] Furthermore, there are two sets of fixed pulleys 205d. When the translation motor 205c is started, it will drive the belt 205e to move. The belt 205e, together with the two sets of fixed pulleys 205d, will drive the moving plate 205f to move. The connecting seat 205a is connected to the outer surface of the lead screw by a thread.

[0032] Preferably, the feeding assembly 206 includes a drive motor 206a adapted to be installed on the side wall of the mounting plate 205b, and an auxiliary pulley 206b connected to the inner wall of the connecting seat 205a via a bearing. The feeding assembly 206 also includes a feeding plate 206c slidably connected to the inner wall of the connecting seat 205a, and a cylinder 206d fixedly installed on the inner wall of the movable housing 204a.

[0033] It should be noted that there are four cylinders 206d. When the material is being fed, the cylinders 206d extend and push the material upward.

[0034] In use, the drive motor 206a is started. The drive motor 206a drives the auxiliary pulley 206b via a V-belt. The side wall of the drive belt is connected to the loading plate 206c. The loading plate 206c reciprocates along the drive belt. The loading plate 206c moves outside the connecting seat 205a. At the same time, the translation motor 205c runs, driving the belt 205e. The belt 205e drives the moving plate 205f to move outward. The moving plate 205f pulls the BIB plate placed on the fixing bar 104 to the upper... On the material plate 206c, the drive motor 206a and the translation motor 205c run in opposite directions, moving the BIB plate into the moving shell 204a. For plates of different heights, the lifting motor 204d runs, driving the lead screw to move and moving the moving seat up and down, which can be used for plates of different heights. The moving motor 204b rotates, driving the gear 204c to rotate. The gear 204c, in conjunction with the rack 203, will drive the moving shell 204a to move along the limit rod 202, thereby transferring the plate.

[0035] In summary, the vertical lifting and positioning of the moving shell 204a is achieved through the meshing transmission of gear 204c and rack 203. The threaded engagement of the lead screw and connecting seat 205a completes the height fine adjustment, enabling the mechanism to adapt to the picking and placing requirements of different sized plates. The translation motor 205c drives the fixed pulley 205d group through belt 205e to drive the moving plate 205f to perform horizontal telescopic movement. In conjunction with the lifting action of cylinder 206d on the loading plate 206c, the plate is smoothly gripped and transferred without damage. The drive motor 206a drives the loading plate 206c to reciprocate through the auxiliary pulley 206b via V-belt transmission, ensuring the stability of the plate conveying process. All transmission components work together to improve work efficiency while ensuring operating accuracy. The overall structure layout is reasonable, the control system is simplified, and it is easy to operate and maintain.
