Description

Technical Field

[0001] The utility model relates to the technical field of PCB board temporary storage equipment, and particularly relates to a temporary storage machine for large boards. Background Technique

[0002] Large boards generally refer to large-sized plates, which are widely used in industries such as electronic manufacturing, printing, packaging, and wood processing. Among them, in the electronic manufacturing industry, large boards refer to PCB boards. These circuit boards are used to connect and fix various electronic components, such as resistors, capacitors, transistors, etc., to achieve the functions of the circuit. The size of the PCB board can be customized according to needs, but large-sized PCB boards require special handling and storage during the production and testing processes.

[0003] During the electronic manufacturing process, a temporary storage machine for PCB boards is usually used, especially on the SMT (Surface Mount Technology) production line, which is a device for temporarily storing PCB (Printed Circuit Board). The PCB board temporary storage machine is a device used to alleviate the production speed problems of front-end and back-end equipment. When the production speed of the front-end equipment is too fast or the back-end equipment malfunctions, causing the accumulation of PCB boards, the temporary storage machine can automatically store the products produced by the front-end equipment to ensure the smooth operation of the production line.

[0004] Currently, when using a PCB board, it is usually necessary to first detect the equipment to determine that the equipment can be in a normal working state, then turn on the equipment, wait for the equipment to complete self-checking, and then accurately place the PCB board on the conveyor belt of the temporary storage machine, and it is necessary to ensure that the PCB position is normal, start the conveyor belt, so that the PCB board enters the temporary storage area, and the temporary storage machine will automatically store it and wait for subsequent use.

[0005] However, when using a PCB board temporary storage machine, since there are large-sized PCB board products, general temporary storage machines cannot carry such products, which will affect the storage of PCB boards and thus affect the production of PCB boards. Content of the Utility Model

[0006] Based on this, the purpose of the utility model is to provide a temporary storage machine for large boards to solve the technical problem that since there are large-sized PCB board products, general temporary storage machines cannot carry such products, which will affect the storage of PCB boards and thus affect the production of PCB boards.

[0007] To achieve the above object, the utility model provides the following technical solutions: A temporary storage machine for large boards, including an appearance frame. A conveyor belt mechanism is arranged inside the appearance frame, and a lifting and temporary storage mechanism is arranged inside the appearance frame. The lifting and temporary storage mechanism includes a group of columns fixedly connected inside the appearance frame, and a slider is slidably connected to the outer surface of the column. A plurality of cross bars are fixedly connected between the group of sliders, and a plurality of temporary storage rods are fixedly connected to the outer surface of the cross bar. A group of lead screws are rotatably connected inside the appearance frame, and a movable block is movably connected to the outer surface of the lead screw. Each movable block is fixedly connected to one side of the corresponding slider. The top of one of the lead screws is connected to the output end of a motor, and the motor is fixedly connected to the inner side of the appearance frame. The outer surfaces of the group of lead screws are connected by a transmission belt.

[0008] By adopting the above technical solutions, when storing PCB boards, the PCB boards can be first conveyed to a specified position through the conveyor belt mechanism, and then a group of lead screws are driven to rotate by the motor and the transmission belt, so that the movable block can move up and down on the outer surface of the lead screw, causing the slider to slide on the outer surface of the vertical rod, and then the temporary storage rod can be driven to move. At the same time, the temporary storage mechanism is a double lead screw lifting mechanism, which has the characteristics of stable lifting and large load capacity, enabling the temporary storage machine to store larger products. And the double lead screw lifting can widen the temporary storage area on the original basis, making it possible to accommodate larger products.

[0009] The utility model is further configured such that the conveyor belt mechanism adopts a roller elastic belt drive design.

[0010] By adopting the above technical solutions, this design will not scratch or damage the PCB boards. The conveying power adopts a single motor drive design, and the speed control motor is matched with the speed of the docking production line. The PCB boards stop in place after entering the conveying section.

[0011] The utility model is further configured such that the appearance frame adopts an embedded skeleton structure.

[0012] By adopting the above technical solutions, the weight of the frame is increased, making the entire equipment more stable and not prone to shaking. Moreover, the appearance of the frame is redesigned, with a beautiful and generous appearance, superior to the conventional square tube welded frame.

[0013] The utility model is further configured such that the temporary storage rod adopts a 304 stainless steel round bar.

[0014] By adopting the above technical solutions, using a 304 stainless steel round bar can provide excellent corrosion resistance, high temperature resistance, workability, strength and toughness, etc. At the same time, it has advantages such as good surface finish and oxidation resistance, avoiding damage to the PCB boards, and thus can better convey the PCB boards.

[0015] The present utility model is further configured such that the gaps between the temporary storage rods intersect with the gaps between the conveyor belt mechanisms, allowing the temporary storage rods to pass through the conveyor belt mechanisms.

[0016] By adopting the above technical solution, when the temporary storage rods pass through the conveyor belt mechanisms, the PCB on the outer surface of the conveyor belt mechanisms is synchronously moved upward, thereby playing a role in temporarily storing the PCB boards. At the same time, the temporarily stored PCB boards are evenly stressed and not easily deformed.

[0017] In summary, the present utility model mainly has the following beneficial effects:

[0018] The present utility model conveys the PCB boards to the designated position through the conveyor belt mechanisms, and then drives a set of lead screws to rotate through the motor and the transmission belt. Thereby, a set of movable blocks can be driven to move up and down on the outer surface of the corresponding lead screws, and then the temporary storage rods can be driven to move. The temporary storage mechanism adopts a double lead screw lifting mechanism, which has the characteristics of stable lifting and large load-bearing, enabling the temporary storage function to store larger products. At the same time, the double lead screw lifting can widen the temporary storage area on the original basis, making it possible to accommodate larger products. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0024] The following will describe the embodiments according to the overall structure of the present utility model.

[0025] A temporary storage machine for large boards, as Figures 1 - 3As shown in the figure, it includes an appearance frame 1. The appearance frame 1 adopts an embedded skeleton structure, which can increase the weight of the frame, make the whole device more stable and not easy to shake. Inside the appearance frame 1, a conveyor belt mechanism 2 and a lifting and temporary storage mechanism 3 are arranged. The conveyor belt mechanism 2 and the lifting and temporary storage mechanism 3 cooperate with each other, so that the storage of PCB boards can be completed. At the same time, the conveyor belt mechanism 2 adopts a roller elastic belt drive design, which will not scratch or damage the PCB board. The conveying power adopts a single-motor drive design, and the speed-regulating motor matches the speed of the docking production line. After the PCB board enters the conveying section, it stops in place.

[0026] Among them, the lifting and temporary storage mechanism 3 includes a group of columns 301 fixedly connected inside the appearance frame 1. The outer surface of the column 301 is slidably connected with a slider 302, so that the slider 302 can move on the outer surface of the corresponding column 301. A number of cross bars 305 are fixedly connected between a group of sliders 302, and a number of temporary storage rods 306 are fixedly connected to the outer surface of the cross bar 305. A group of lead screws 304 are rotatably connected inside the appearance frame 1, and the outer surface of the lead screw 304 is movably connected with a movable block 307. Each movable block 307 is fixedly connected to one side of the corresponding slider 302. The top of one of the lead screws 304 is connected to the output end of a motor 303, and the motor 303 is fixedly connected to the inner side of the appearance frame 1. The outer surfaces of a group of lead screws 304 are connected by a transmission belt 308. By the motor 303 and the transmission belt 308, a group of lead screws 304 can be driven to rotate, so that a group of movable blocks 307 drive the cross bar 305 and the temporary storage rod 306 to move smoothly.

[0027] Therefore, when in use, the PCB board is conveyed to a specified position by the conveyor belt mechanism 2, and then a group of lead screws 304 are driven to rotate by the motor 303 and the transmission belt 308, so that a group of movable blocks 307 can be driven to move on the outer surface of the corresponding lead screw 304, and then the temporary storage rod 306 can be driven to move. The lifting and temporary storage mechanism 3 adopts a double-lead screw lifting mechanism, which has the characteristics of stable lifting and large load-bearing, so that the temporary storage function can store larger products. At the same time, the double-lead screw lifting can widen the temporary storage area on the original basis, so that larger products can be compatible.

[0028] In this embodiment, the temporary storage rod 306 is made of 304 stainless steel rod, which makes the temporary storage rod 306 strong and durable, with a clean surface, avoiding damage to the product. At the same time, the gap between the temporary storage rods 306 intersects with the gap between the conveyor belt mechanism 2, allowing the temporary storage rod 306 to pass through the conveyor belt mechanism 2. Therefore, the PCB board on the outer surface of the conveyor belt mechanism 2 can be driven to move upward by the temporary storage rod 306, so as to play a role in temporarily storing the PCB board, and at the same time, the temporarily stored PCB board is evenly stressed and not easy to deform.

[0029] Working principle: Push the PCB board onto the conveyor line, and then convey the PCB board to the temporary storage position through the conveyor belt mechanism 2. After the PCB board is conveyed to the specified position, the conveyance stops, causing the lifting and temporary storage mechanism 3 to move upward. The temporary storage rod 306 tops up the product, separating it from the conveyor line. The temporary storage rod 306 moves upward a certain distance and then stops. The conveyor line starts, bringing the next product into place. The conveyance stops again, and the temporary storage rod 306 rises to lift the product. This process repeats until the temporary storage mechanism is full. When the backend equipment reaches the operating state, the temporary storage machine then conveys the temporarily stored products to the next working station through the conveyor flow.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present invention, make modifications, substitutions, and variations that do not contribute creatively to the embodiments as needed.
