Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic lifting device for a material tray. Background Technology

[0002] In automated production equipment, the tray lifting mechanism is a key component for achieving precise material positioning and transfer. Current technologies typically employ a single drive method for tray lifting mechanisms, including pneumatic, electric, hydraulic, electromagnetic, chain, and servo-electric types. Each of these mechanisms has its advantages and disadvantages; while some have strengths, others have significant drawbacks, limiting their application scenarios and making them unsuitable for more complex working conditions. For example:

[0003] Pneumatic drive: Although it has the advantages of low cost and fast response, it has problems such as low positioning accuracy (usually only ±1mm), thrust is greatly affected by air pressure fluctuations, and it cannot achieve complex motion trajectories.

[0004] Electric drives (such as stepper / servo motors): Although they can achieve high-precision positioning (±0.1mm), they require high-power motors when high thrust is needed, resulting in large size and high cost.

[0005] Hydraulic drive: high thrust but complex system, difficult maintenance and risk of oil leakage;

[0006] Chain or synchronous belt drive: simple in structure but low in transmission accuracy, easy to wear, and prone to cumulative errors after long-term use;

[0007] Electromagnetic drive: only suitable for short stroke and light load scenarios, and there is a risk of electromagnetic interference.

[0008] Therefore, the aforementioned single drive method is difficult to simultaneously meet the requirements of high precision, high thrust, low cost, and compact design in practical applications. Especially in the semiconductor or precision electronics industry, tray lifting requires micron-level positioning accuracy, as well as rapid response and high load-bearing capacity. Traditional solutions require multiple mechanisms to achieve this, resulting in system complexity and high failure rate.

[0009] At the same time, the existing mechanisms are not compatible with material trays of different sizes, resulting in poor flexibility in actual use. Utility Model Content

[0010] The technical problem to be solved by this utility model is to provide an automatic material tray lifting device, which solves the problems of difficulty in automatic material tray feeding and poor flexibility of use under complex working conditions.

[0011] The technical solution adopted by this utility model to solve its technical problem is as follows: an automatic tray lifting device, including a bracket, a linear lifting module is provided on the bracket, the moving part of the linear lifting module is connected to a mounting plate, and a secondary tray lifting component is provided on the mounting plate; the linear lifting module drives the secondary tray lifting component to perform a primary lifting action; the secondary tray lifting component performs a secondary lifting action; a tray telescopic component is also provided on the bracket; the tray telescopic component is located above the secondary tray lifting component; the secondary tray lifting component lifts the tray on the tray telescopic component from bottom to top; anti-tipping components are respectively provided on both sides of the tray telescopic component.

[0012] Furthermore, the secondary lifting assembly for the material tray described in this utility model includes a cylinder, which is connected to a mounting plate, and a fixing plate is connected to the telescopic end of the cylinder; a lifting plate is provided on the fixing plate.

[0013] Furthermore, the lifting plate of this utility model is provided with a positioning block that cooperates with the positioning groove at the bottom of the material tray.

[0014] Furthermore, a right-angle support plate is provided between the fixed plate and the lifting plate described in this utility model.

[0015] Furthermore, the pallet telescopic assembly of this utility model includes a push-pull frame, the two long sides of which support the edge of the material tray; and a movable limiting block is provided on the push-pull frame.

[0016] Furthermore, the anti-tipping component of this utility model includes mounting feet and a baffle disposed on the mounting feet, wherein the baffle is a lightweight baffle.

[0017] The beneficial effects of this utility model are that it solves the defects existing in the background technology. By combining linear modules and cylinders, and supplementing them with a clever mechanical structure, it can not only automatically lift the material tray, but also give full play to the advantages of each to achieve efficient, precise and reliable motion control. It has the advantages of high precision and high stability, fast response speed, strong load-bearing capacity, flexible motion control and high reliability. At the same time, this utility model has made a clever structural design, using a few simple parts to complete the blocking function of the material tray, preventing the material tray from tipping over due to excessive stacking. It achieves structural standardization, simplifies structural design, reduces production costs, can adapt to material trays of multiple specifications, and improves production efficiency.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figures 1-3 The illustrated automatic tray lifting device includes a support 1, on which a linear lifting module 2 is mounted. A moving part 3 of the linear lifting module 2 is connected to a mounting plate 4, and a secondary tray lifting assembly 5 is mounted on the mounting plate 4. The linear lifting module 2 drives the secondary tray lifting assembly 5 to perform a primary lifting action; the secondary tray lifting assembly 5 then performs a secondary lifting action.

[0024] like Figure 2 As shown, the secondary lifting assembly 5 for the material tray includes a cylinder 51, which is connected to the mounting plate 4. A fixing plate 52 is connected to the telescopic end of the cylinder 51. In this embodiment, the fixing plate 52 is shaped like a "7". A lifting plate 53 is provided on the top of the fixing plate 52. To better coordinate with the material tray during lifting and ensure the stability and accuracy of the lifting, a positioning block 54 is provided on the lifting plate to cooperate with the positioning groove at the bottom of the material tray. To increase the connection strength, a right-angle support plate 55 is provided between the fixing plate and the lifting plate.

[0025] The support frame is also equipped with a tray telescopic assembly 6; the tray telescopic assembly 6 is located above the material tray secondary lifting assembly; the material tray secondary lifting assembly lifts the material tray on the tray telescopic assembly from bottom to top; anti-tipping components 7 are respectively provided on both sides of the tray telescopic assembly.

[0026] like Figure 3 The pallet telescopic assembly 6 shown includes a push-pull frame 61, whose two long sides support the edge of the pallet; the push-pull frame is provided with a movable limiting block 62. The push-pull frame can be pushed and pulled manually, and the movable limiting block on the push-pull frame can be adjusted according to the size and specifications of the pallet.

[0027] The anti-tipping component 7 includes mounting feet 71 and baffles 72 disposed on the mounting feet. The baffles are made of lightweight sheet metal and can prevent the trays from being overstacked and tipping over.

[0028] During operation, the manual stacking of trays onto the tray telescopic assembly is performed. The tray telescopic assembly can be adjusted according to the size and specifications of the trays. The anti-tipping assembly's sheet metal baffle prevents the trays from tipping over due to excessive stacking. After the trays are placed, the linear module's mover drives the tray secondary lifting assembly to lift them once. Once the set height is reached, the cylinder is activated to lift them a second time, sending the trays to the appropriate position.
