Description

Technical Field

[0001] The present invention relates to the technical field of memory bar processing, and in particular to a flexible conveying and boxing device for memory bar production. Background Art

[0002] A memory stick refers to a component in a computer used to temporarily store data. It is widely used in personal computers, servers, and other electronic devices. The memory stick is in the shape of a rectangular sheet. The memory chip in the memory stick is a high-end semiconductor chip, which has very high requirements for production and processing equipment. It requires extremely sophisticated equipment to process it during production.

[0003] During the production process, memory sticks need to be cut and separated into panels. After separation, the memory sticks need to be inspected to check whether there are problems such as overcutting. Defective products need to be rejected, and qualified products need to be transferred and boxed.

[0004] In existing equipment, after defective products are identified, they will be transferred through mechanisms such as suction cups to realize the process of packing good products into boxes and removing defective products. However, some defective products can be returned for repair, and existing equipment cannot collect these products.

[0005] At the same time, the existing technology requires a clamping mechanism for grabbing and transporting memory sticks. Since the surface of the memory stick is fragile, the automated equipment needs to achieve high precision when transferring it, but overpressure may still occur, causing damage to the board.

[0006] In the existing technology, the clamping mechanism used has a non-elastic structure design, which can easily cause damage to the board when clamping the memory stick. At the same time, the device uses a multi-group merging method when collecting the boards, and cannot integrate the inspection process into it.

[0007] During the inspection process, since the memory sticks are in sheet form, they need to be placed horizontally individually, and problems exist when taking pictures and analyzing with inspection cameras. Existing equipment generally separates the inspection equipment and the boxing equipment to form an inspection and boxing assembly line, but this assembly line occupies a large area and requires a long time for transportation. Summary of the Invention

[0008] Based on this, it is necessary to provide a memory stick tray device that integrates detection and packaging to address the problems raised in the background technology. The device has a compact structure and adopts a flexible clamping structure to achieve lossless transfer of memory sticks.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a memory bar swing machine, comprising a frame, on which a first Y-axis linear module and a second Y-axis linear module are provided, and the first Y-axis linear module is provided with an X-axis screw module and a suction cup module that displace along the Y-axis.

[0010] The transfer carrier is arranged on the second Y-axis linear module. The upper end of the second Y-axis linear module is provided with a camera detection mechanism for detecting good, repaired and defective memory sticks carried by the transfer carrier, thereby distinguishing the three qualities of the memory sticks and saving material resources.

[0011] Among them, the transfer carrier includes a carrier base, and the upper end of the carrier base is provided with multiple groups of accommodating slots that can accommodate horizontally placed memory bars. The edge of the accommodating slot is provided with a first clamping head for flexibly clamping the memory bar, so that the memory bar is damaged when the textile is clamped.

[0012] The flipping mechanism can be raised and lowered and is arranged at the work station behind the camera detection mechanism. After the transfer carrier transfers the memory stick to the flipping mechanism, the flipping mechanism descends to flexibly clamp the horizontal memory stick and flip it 90 degrees, making it convenient for the subsequent grasping mechanism to grasp the memory stick and at the same time, making it convenient for the memory stick to be vertically inserted into the carrier.

[0013] The gripping mechanism realizes X-axis and Y-axis displacement through the first Y-axis linear module and the X-axis lead screw module, and is used to flexibly clamp and transfer the memory bar after being flipped by the flipping mechanism.

[0014] Among them, the grasping mechanism includes multiple groups of lifting and flexible clamping mechanisms with adjustable spacing. The lifting and flexible clamping mechanisms include a T-shaped seat and a lifting seat that is lifted and lowered by a lifting cylinder. Two groups of relatively arranged product clamping blocks are provided at the bottom of the lifting seat. The two groups of product clamping blocks clamp the flipped memory bars through a second clamping cylinder. The output end of the second clamping cylinder is elastically connected to the product clamping block to achieve flexible clamping of the memory bars in a vertical state.

[0015] A full tray stacker is provided at the rear station of the flipping mechanism, and is used to store the carrier tray carrying the good memory sticks. The gripping mechanism clamps the good memory sticks flipped by the flipping mechanism into the carrier tray provided in the full tray stacker, and is used to stack and store the good memory sticks.

The defective product transfer platform is provided with a return product transfer plate. A carrier for carrying return products is placed on the return product transfer plate. The defective product transfer platform is provided with a defective product placement port for placing defective products, which is used to distinguish defective products from return products.

The camera detection mechanism 11 uses the camera detection light source 27 and the camera calibration plate 26 to locate and photograph the memory bars, detect the memory bar size and read the code in turn, and determine whether there are problems such as overcutting in the group of memory bars on the transfer carrier 2. The memory bars on the transfer carrier 2 are marked as good products, returned products, and defective products, and their positions are marked.

[0085] The second Y-axis linear module 52 transfers the transfer carrier 2 to the lower end of the lifting frame 41, and the lifting frame 41 is lowered by the cylinder. The transfer carrier 2 passes through the through window 411. After the sensor senses that the memory bar is in place, the lifting frame 41 stops descending, and the width adjustment motor 44 drives the two flip assemblies 42 to approach the edge of the memory bar. After the clamping head 424 contacts the two ends of the memory bar, the memory bar is elastically clamped by the second spring connector 425. At this time, the negative pressure on the transfer carrier 2 is closed, and the first clamping cylinder 210 drives the first clamping head 24 to release the clamping state of the memory bar. The transfer carrier 2 returns to the board separator through the second Y-axis linear module 52, and the lifting frame 41 is raised by the cylinder. The clamped memory bar rises synchronously, and the flip motor 45 drives the flip drive shaft 47 to rotate, and the sliding bearing assembly 421 and the flip drive gear shaft 423 are driven to rotate synchronously through the belt, driving the memory bar clamped by the clamping head 424 to rotate synchronously 90 degrees. The flip in place sensor 48 detects whether the memory bar is flipped in place;

[0086] The grabbing mechanism 3 is displaced by the first Y-axis linear module 5 and the X-axis screw module 51. The number of lifting flexible clamping mechanisms 32 is consistent with the number of memory bars. The grabbing mechanism 3 moves to above the flipping mechanism 4. The lifting cylinder 35 drives the lifting seat 34 to descend. The product sensor 312 senses the position of the memory bar. The second clamping cylinder 36 drives the first sliding block 37, the second sliding block 38 and the product clamping block 39 to clamp the memory bar. Flexible clamping is achieved through the first spring connector 371 and the second spring 311. After clamping, it is raised by the lifting cylinder 35. Each clamped memory bar is recorded as a good product, a returned product and a defective product through the system.

[0087] The first Y-axis linear module 5 and the X-axis screw module 51 are used to place the good product and the repaired product memory sticks on the full tray stacker 8 and the tray 7 on the repaired product transfer plate 101, respectively, and the defective products are placed on the defective product placement port 104 for collection.

[0088] The carrier tray 7 on the full tray stacking machine 8 can be raised and lowered by the lifting plate 802, so the carrier tray 7 can be stacked and the number of layers can be set. When the number of layers is full, it is transferred to the receiving platform 807 by the belt line and manually taken out;

[0089] The carrier tray 7 on the empty tray stacking machine 9 is an empty tray. The stacked empty carrier trays 7 are manually placed on the receiving platform 807 of the empty tray stacking machine 9, and the empty and stacked carrier trays 7 are transferred to the lifting plate 802 of the empty tray stacking machine 9 through the belt line. The empty carrier tray 7 is adsorbed by the suction cup module 6, and the suction cup module 6 is displaced through the first Y-axis linear module 5 and placed on the lifting plate 802 of the full tray stacking machine 8 and the returned product transfer plate 101. When the carrier tray 7 on the returned product transfer plate 101 is full, the returned product transfer motor 102 drives the returned product transfer belt 103 to rotate, driving the returned product transfer plate 101 to the equipment material picking position for manual removal.

[0090] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
