Description

Technical Field

[0001] This utility model particularly relates to a stacked lifting device for transferring blister trays. Background Technology

[0002] As a core packaging material for electronic components and precision parts, the storage and turnover efficiency of blister packs directly impacts the production cycle and material safety of downstream customers. In stacked storage and lifting equipment, the reliability of the locking structure is crucial for ensuring the stability of the support platform (shelf) and preventing accidental slippage or damage to the blister packs. Currently, while common locking methods achieve basic functionality, they suffer from several shortcomings that are incompatible with actual industry needs: 1. Electromagnetic locking method: This method relies on energizing an electromagnet to generate magnetic attraction, thus fixing the shelf to the frame. While this method offers strong locking force and fast response, it has significant drawbacks: the locking state requires continuous power; any unexpected power outage will cause it to fail instantly, posing a risk of the shelf falling and creating a significant safety hazard. Furthermore, its manufacturing cost is high, and it may generate electromagnetic interference during operation, making it unsuitable for applications requiring strict electromagnetic environments, such as those involving precision electronic components.

[0003] 2. Friction block clamping locking: This method uses a cylinder or screw to drive the friction block to press against the guide post, achieving locking through friction. To achieve sufficient locking force, this structure requires a large drive source, resulting in a bulky and complex overall design. Furthermore, as a wear component, the friction block will wear down over time, leading to a decrease in locking force. Regular inspection and replacement are necessary, resulting in high maintenance costs and the potential for instability due to reduced locking force.

[0004] The inherent limitations of the aforementioned locking methods make it difficult to meet the needs of blister trays in efficient and safe handling scenarios. Therefore, there is an urgent need for a locking solution that is simple in structure, reliable in locking, requires no continuous power supply, and is easy to maintain, in order to improve the overall efficiency and safety of blister tray storage and transportation. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a stacked lifting device for transferring blister trays.

[0006] A stackable lifting device for transferring blister trays includes a frame with a shelf slidably mounted on it for supporting the blister trays. A lifting mechanism is provided on the frame to drive the shelf to move vertically. Multiple limiting rods are fixed on the shelf, all forming a positioning station for the blister trays. Locking structures for locking the shelf are also provided on opposite sides of the frame. Each locking structure includes a mounting base fixed to the frame, a latch hinged to the mounting base via a pin, a positioning rod fixed to the shelf, and a locking platform threadedly engaged with the positioning rod. The latch has a locking opening through which the positioning rod passes. By tightening the locking platform, the shelf is pressed against the latch, thereby locking the shelf relative to the frame.

[0007] Preferably, the lifting mechanism includes screws symmetrically mounted on both sides of the frame, a movable plate connected to the screws, and a motor for driving the screws to rotate; guide rods fixed to the frame are also provided on both sides of the movable plate, and the movable plate and the guide rods form a sliding fit; the output shaft of the motor is connected to the screws and is used to drive the screws to rotate, thereby driving the movable plate to move vertically along the guide rods; the locking structure is used to lock the shelf and the movable plate together.

[0008] Preferably, the shelf is equipped with a handle, and the bottom of the frame is provided with rollers, so that the shelf can slide along the rollers to be pulled out of the frame.

[0009] Preferably, there are eight limiting rods, and four limiting rods are arranged in a group to form an independent storage station, thus forming two storage stations in total.

[0010] Preferably, the latch has a U-shaped structure.

[0011] Preferably, a pressure plate is further provided between the locking platform and the latch; when the locking platform is tightened to the positioning rod, it is pressed against the latch by the pressure plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes the threaded engagement between the locking platform and the positioning rod to generate a strong mechanical preload, firmly pressing the latch onto the positioning rod. This rigid connection completely eliminates the gaps present in pin-type locks, making the shelf and the moving plate a stable whole in the locked state, effectively preventing minor wobbling. The entire locking structure is achieved entirely through mechanical components (latch, positioning rod, and locking platform), and its locking state does not rely on any electricity for maintenance. Compared to electromagnetic locks, this structure fundamentally eliminates the safety hazard of locking failure due to accidental power outages, greatly improving the safety and reliability of equipment operation.

[0020] A stackable lifting device for transferring blister trays includes a frame 1, on which a shelf 3 for carrying blister trays 2 is slidably mounted. A lifting mechanism for driving the shelf 3 to move vertically is provided on the frame 1. Multiple limiting rods 4 are fixed on the shelf 3, all of which together form a placement position for positioning the blister trays 2. Locking structures for locking the shelf 3 are also provided on opposite sides of the frame 1. The locking structures include a mounting base 51 fixed to the frame 1, a latch 53 hinged to the mounting base 51 via a pin 52, a positioning rod 54 fixed to the shelf 3, and a locking platform 55 threadedly engaged with the positioning rod 54. The latch 53 has a locking opening 56 through which the positioning rod 54 passes. By tightening the locking platform 55 to press it against the latch 53, the shelf 3 is locked relative to the frame 1.

[0021] Furthermore, the lifting mechanism includes screws 61 symmetrically installed on both sides of the frame 1, a movable plate 62 connected to the screws 61, and a motor 63 for driving the screws 61 to rotate; guide rods 64 fixed on the frame 1 are also provided on both sides of the movable plate 62, and the movable plate 62 and the guide rods 64 form a sliding fit; the output shaft of the motor 63 is connected to the screws 61 and is used to drive the screws 61 to rotate, thereby driving the movable plate 62 to move vertically in a straight line along the guide rods 64; the locking structure is used to lock the shelf 3 and the movable plate 62 together.

[0022] Furthermore, a handle 7 is installed on the shelf 3, and a roller 8 is provided at the bottom of the frame 1. The shelf 3 can slide along the roller 8 to be pulled out of the frame 1.

[0023] Furthermore, there are eight limiting rods 4, and four limiting rods 4 are arranged in a group to form an independent storage station, thus forming two storage stations in total.

[0024] Furthermore, the latch 53 has a U-shaped structure.

[0025] Furthermore, a pressure plate 540 is provided between the locking platform 55 and the latch 53; when the locking platform 55 is tightened to the positioning rod 54, it is pressed against the latch 53 by the pressure plate 540.

[0026] The working principle of this utility model is as follows: As an embodiment 1, the frame 1 of this application is the main structural body. The shelf 3 is slidably disposed within the frame 1, and a handle 7 is provided at the front end of the shelf 3 for easy pulling out by the operator. The lifting mechanism is symmetrically disposed on both sides of the frame 1, each side including a vertically installed screw 61. Guide rods 64 are respectively provided on both sides of the screw 61. A movable plate 62 is connected to the screw 61, and the guide rods 64 are passed through both ends of the movable plate 62. A motor 63 is connected to the screw 61, that is, the motor 63 drives the screw 61 to rotate, causing the movable plate 62 to move vertically along the guide rods 64, thereby achieving a smooth lifting process without deviation. The two sides of the shelf 3 are fixed to the movable plates 62 on both sides by a locking structure.

[0027] The placement method of the blister tray 2 can be as follows: eight limiting rods 4 are vertically installed on the shelf 3. These eight limiting rods 4 are divided into two groups of four, forming two independent placement positions for positioning the square blister tray 2. Through holes 1-1 are pre-drilled at the four corners of the blister tray 2. The diameter of the limiting rod 4 is adapted to the through holes 1-1, allowing it to be inserted into them, thereby effectively preventing the blister tray 2 from shifting during transportation.

[0028] The operation of the locking structure is as follows: a locking structure is provided on each side of the frame 1. The locking structure is used to connect and fix the movable plate 62 and the shelf 3. As an embodiment 1, the structural fit of the locking structure is as follows: a mounting base 51 is fixed on the movable plate 62, and a U-shaped latch 53 is hinged to the mounting base 51 by a pin 52. The latch 53 can rotate around the pin 52, and its open end forms a locking port 56. A positioning rod 54 is fixed at the corresponding position of the shelf 3. A locking platform 55 is screwed on the positioning rod 54. A pressure plate 540 is provided between the locking platform 55 and the positioning rod 54 to fasten the U-shaped latch 53 onto the positioning rod 54. By tightening the locking platform 55, the locking platform 55 presses the pressure plate 54 to fix the U-shaped latch 53 onto the positioning rod 54.

[0029] The usage scenario is as follows: First, the empty shelf 3 is pushed into the frame 1 and locked to the moving plate 62 by the locking structure. Then, the motor 63 of the lifting mechanism is started, driving the screw 61 to rotate and raising the shelf 3 to a certain height. The operator aligns the through holes 1-1 at the four corners of the blister tray 2 with a set of limit rods 4 (i.e., a storage station) and lowers it to complete the filling of one station. When the shelf 3 is full, the lifting mechanism drives it to descend to a certain position (or transfer height). When it is necessary to transfer the shelf 3, first loosen the locking plate 55 to separate it from the lock 53, remove the gasket 54, and then rotate the U-shaped lock 53 to make its locking port 56 leave the positioning rod 54, thereby completely releasing the lock. Then, the worker can hold the handle 7 and use the support of the bottom rollers 8 to easily pull the entire fully loaded shelf 3 out of the frame 1 and transfer it to the AGV trolley or transfer platform for independent transfer.

[0030] This invention utilizes the threaded engagement between the locking platform 55 and the positioning rod 54 to generate a strong mechanical preload, firmly pressing the latch 53 onto the positioning rod 54. This rigid connection completely eliminates the gaps present in pin-type locks, ensuring that the shelf 3 and the moving plate 62 form a stable whole in the locked state, effectively preventing minor wobbling. The entire locking structure is achieved entirely using mechanical components such as the mounting base 51, latch 53, positioning rod 54, and locking platform 55, and its locking state does not rely on any electrical power. Compared to electromagnetic locks, this structure fundamentally eliminates the safety hazard of locking failure due to accidental power outages, greatly improving the safety and reliability of equipment operation.

[0031] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
