Description

Technical Field

[0001] This invention relates to the field of memory module processing technology, and in particular to a flexible conveying and packaging device for memory module production. Background Technology

[0002] Memory modules are components used in computers for temporary data storage. They are widely used in personal computers, servers, and other electronic devices. Memory modules are rectangular in shape, and the memory chips in memory modules are high-end semiconductor chips, which require very high-precision equipment to process them.

[0003] During the production process, memory modules need to be cut and separated into boards. After separation, the memory modules need to be inspected to check for problems such as overcutting. Defective products need to be rejected, and qualified products are transferred and packaged.

[0004] In existing equipment, after defective products are identified, they are transferred by suction cups and other mechanisms to achieve the process of packaging good products and rejecting defective products. However, some defective products are reworkable, and existing equipment cannot collect these products.

[0005] Meanwhile, existing technologies require clamping mechanisms for gripping and transporting memory modules. Since the surface of memory modules is easily damaged, automated equipment needs to achieve high precision during transfer, but overpressure can still occur, causing damage to the substrate.

[0006] In the existing technology, the clamping mechanism has an inelastic structure design, which can easily damage the board when clamping the memory module. At the same time, the equipment uses a multi-group merging method when collecting the boards, which cannot integrate the inspection process.

[0007] In the testing process, since memory modules are in sheet form, they need to be placed horizontally individually and photographed by a testing camera to analyze any problems. Existing equipment usually separates the testing equipment and the packaging equipment to form a testing and packaging assembly line, but this assembly line occupies a large area and requires a long transfer time. Summary of the Invention

[0008] Based on this, it is necessary to provide a memory module tray loading device that integrates testing and packaging to address the problems raised in the background technology. This device has a compact structure and adopts a flexible clamping structure to achieve non-destructive transfer of memory modules.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a memory module swivel machine, comprising a frame, wherein a first Y-axis linear module and a second Y-axis linear module are provided on the frame, and the first Y-axis linear module is provided with an X-axis lead screw module and a suction cup module that are displaced along the Y-axis.

[0010] A transfer carrier is mounted on a second Y-axis linear module. The upper end of the second Y-axis linear module is equipped with a camera detection mechanism for detecting good, reworked, and defective memory modules carried by the transfer carrier, thereby distinguishing between the three quality levels of the memory modules and saving material resources.

[0011] The transfer carrier includes a carrier base, the upper end of which is provided with multiple sets of receiving slots for horizontally placed memory modules. The edge of the receiving slot is provided with a first clamping head for flexibly clamping the memory module, which may cause damage to the memory module when it is clamped.

[0012] The flipping mechanism is vertically mounted at the rear station of the camera detection mechanism. The transfer carrier transfers the memory module to the flipping mechanism. The flipping mechanism descends to flexibly clamp the horizontally positioned memory module and flips it 90 degrees, which facilitates the subsequent gripping mechanism to grip the memory module. At the same time, it facilitates the vertical insertion of the memory module into the carrier disk.

[0013] The gripping mechanism achieves X-axis and Y-axis displacement through a first Y-axis linear module and an X-axis lead screw module, which is used to flexibly clamp and transfer the memory module after it has been flipped by the flipping mechanism.

[0014] The gripping mechanism includes multiple sets of adjustable-spacing lifting flexible gripping mechanisms. Each lifting flexible gripping mechanism includes a T-shaped base and a lifting seat that is lifted by a lifting cylinder. The bottom of the lifting seat is provided with two sets of product clamping blocks arranged opposite to each other. The two sets of product clamping blocks clamp the flipped memory stick 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 stick in a vertical state.

[0015] A full-disc stacking machine is set at the station after the flipping mechanism. It is used to store a tray carrying good memory modules. The gripping mechanism clamps the good memory modules flipped by the flipping mechanism into the tray provided by the full-disc stacking machine for stacking and storing the good memory modules.

[0016] A defective product transfer station is provided at the rear station of the full-tray stacking machine. The defective product transfer station is equipped with a rework transfer plate, on which a tray for carrying rework products is placed. The defective product transfer station is also equipped with a defective product inlet for dispensing defective products, which is used to distinguish between defective products and rework products.

[0017] An empty tray stacking machine is installed at the work station behind the defective product transfer table. The empty tray stacking machine is used to stack and store empty trays.

[0018] The suction cup module transfers the trays from the empty tray stacker to the repair transfer plate and the full tray stacker.

[0019] In a preferred embodiment, the present invention can be further configured as follows: the receiving groove is provided with a negative pressure hole for connecting to a negative pressure system through an air pipe interface; the bottom of the carrier base is provided with a first clamping cylinder; the first clamping cylinder drives the first clamping head to move through a clamping connecting rod; and a first spring is sleeved on the outside of the clamping connecting rod to achieve elastic clamping of the memory module.

[0020] By adopting the above technical solution, the memory module can be firmly fixed in the receiving slot through the negative pressure hole. When the first spring is in the released state, it drives the first clamping head to cooperate with the receiving slot and press the memory module in the receiving slot. When the first spring is in the compressed state, the first clamping cylinder pulls the first clamping head and releases the memory module in the receiving slot, thereby achieving flexible clamping of the memory module.

[0021] In a preferred embodiment, the present invention can be further configured as follows: camera detection light sources are provided on both sides of the carrier base to illuminate the edge of the memory module, facilitating the detection camera to detect issues such as whether the edge of the memory module is overcut; a camera calibration plate is provided at the end of the carrier base for camera positioning; and product presence sensors are provided on both sides of the carrier base to detect whether there is material leakage.

[0022] In a preferred embodiment, the present invention can be further configured as follows: the flipping mechanism includes a lifting frame that is raised and lowered by a cylinder, the end face of the lifting frame is provided with a passage window for accommodating a transfer vehicle, the lifting frame is provided with two sets of mirror-arranged flipping components, and the two sets of flipping components are driven to achieve relative displacement in the X-axis direction, the flipping component includes a width adjustment plate, and the width adjustment plate is provided with multiple sets of clamps for clamping both ends of the memory module, the clamps are elastic and rotate synchronously by the drive component.

[0023] By adopting the above technical solution, the memory module carried by the transfer carrier can be flexibly clamped and rotated 90 degrees, so that the memory module is in a vertical state, which makes it easier for the subsequent gripping mechanism to grab and put it into the carrier.

[0024] In a preferred embodiment, the present invention can be further configured as follows: the upper end of the lifting frame is provided with support plates on both sides, and a reverse screw is rotatably connected between the two ends of the two sets of support plates. The two sets of reverse screws rotate synchronously through a width-adjusting motor and a drive belt, thereby driving the two sets of flipping components to synchronously adjust the width between them.

[0025] A flip drive shaft is rotatably provided between the ends of the two sets of support plates. The flip drive shaft is connected to the width adjustment plate through a sliding bearing assembly. The flip drive shaft rotates through a flip motor and drives multiple sets of clamps to rotate synchronously.

[0026] By adopting the above technical solution, the synchronization of clamping the memory module and the synchronization of flipping the memory module are achieved.

[0027] In a preferred embodiment, the present invention can be further configured such that: multiple sets of flip drive gear shafts are rotatably connected side by side to the outer wall of the width adjustment plate, and the flip drive gear shafts are elastically connected to the clamp through the width adjustment plate via a second spring connector;

[0028] The flip drive gear shaft includes two coaxial drive gears. The outer drive gear and the inner drive gear of adjacent flip drive gear shafts are connected by belt drive. The flip drive gear shaft near the sliding bearing assembly is connected to the sliding bearing assembly by belt drive.

[0029] In a preferred embodiment, the present invention can be further configured such that the lifting frame is provided with a flip-in sensor for monitoring whether the memory module is flipped into position.

[0030] By adopting the above technical solution, the memory stick is ensured to be in a vertical position after being flipped, improving the grasping accuracy and preventing tilting during picking and placing.

[0031] In a preferred embodiment, the present invention can be further configured as follows: the lifting flexible clamping mechanism is flat, the upper end of the lifting seat is provided with two sets of first guide rods slidably installed on both sides of the lower end of the T-shaped seat, the second clamping cylinder is fixed at both ends of the lifting seat, and the output end of the second clamping cylinder is elastically connected to the first sliding block through the first spring connector, the bottom of the lifting seat is slidably installed with two sets of symmetrically distributed second sliding blocks through the linear rail, the first sliding block and the second sliding block are fixedly connected, and the product clamping block is adjustablely installed at the bottom of the second sliding block.

[0032] By adopting the above technical solution, it is convenient to grab memory modules of various specifications. At the same time, it is flexible during grabbing to achieve flexible grabbing. In addition, the lifting flexible clamping mechanism saves space through the sheet structure design, and the structure is compact.

[0033] In a preferred embodiment, the present invention can be further configured such that the rework transfer plate is slidably mounted on the defective product transfer platform, and is displaced along the X-axis direction on the defective product transfer platform by a rework transfer motor and a rework transfer belt.

[0034] By adopting the above technical solution, it is convenient to manually remove the tray containing the returned products.

[0035] In a preferred embodiment, the present invention can be further configured such that: the full-disc stacking machine and the empty-disc stacking machine have the same structure, both including a vertical frame, a positioning frame at the upper end of the vertical frame, and a lifting plate that is raised and lowered by a Z-axis lifting motor inside the positioning frame, the lifting plate being used to drive the lifting.

[0036] The side ends of the positioning frame are respectively provided with front and rear positioning components and left and right positioning components for positioning the carrier plate;

[0037] The vertical frame has a receiving platform at its bottom front end.

[0038] In summary, the present invention has at least one of the following beneficial technical effects:

[0039] This invention utilizes a transfer carrier, a camera inspection mechanism, and a flipping mechanism to inspect horizontal memory modules and then flip them vertically, facilitating subsequent transport of the memory modules and combining the inspection and packaging processes into a single device.

[0040] The camera inspection agency distinguishes between good, refurbished, and defective memory modules and categorizes them accordingly. The categorization of refurbishable products saves on material costs.

[0041] The transfer carrier, flipping mechanism, and gripping mechanism all use elastic clamping when clamping the memory module, achieving flexible clamping of the memory module and preventing damage to it.

[0042] This invention has a compact structure and high working efficiency. Attached Figure Description

Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] exist Figure 1-11 In the illustrated embodiment, the present invention provides a technical solution: a memory module stacking machine, including a frame 1, on which a first Y-axis linear module 5 and a second Y-axis linear module 52 are provided. The first Y-axis linear module 5 is positioned above the second Y-axis linear module 52. The first Y-axis linear module 5 is provided with an X-axis lead screw module 51 that is displaced along the Y-axis and a suction cup module 6. The suction cup module 6 is externally connected to a negative pressure device and is liftable, used to pick up the carrier plate 7 for displacement, which is achieved by the first Y-axis linear module 5 displaced along the Y-axis.

[0059] like Figures 1-3 As shown, the transfer carrier 2 is set on the second Y-axis linear module 52. The upper end of the second Y-axis linear module 52 is provided with a camera detection mechanism 11 for detecting good, reworked and defective memory modules carried by the transfer carrier 2.

[0060] The transfer carrier 2 includes a carrier base 21. The upper end of the carrier base 21 is provided with multiple sets of parallel storage slots 22 that can accommodate horizontally placed memory modules. The edges of adjacent storage slots 22 are provided with first clamping heads 24 that flexibly clamp the memory modules.

[0061] The receiving groove 22 is provided with a negative pressure hole 23 for connecting to a negative pressure system via an air pipe interface 25. The bottom of the carrier base 21 is provided with a first clamping cylinder 210 and two shaft bases 215. A guide sliding rod 214 is fixedly provided between the two shaft bases 215. A clamping base 213 is slidably sleeved on the guide sliding rod 214. The clamping base 213 is fixedly connected to a first clamping head 24. The receiving groove 22 has a through hole penetrating the carrier base 21. The first clamping head 24 is slidably disposed within the through hole. The first clamping cylinder 210 drives the clamping base 213 and the first clamping head 24 to move via a clamping connecting rod 212. A first spring 211 is sleeved on the outside of the clamping connecting rod 212. The end of the first spring 211 is connected to the shaft base 21. 5. When the first spring 211 is in the released state, it drives the first clamping head 24 to cooperate with the receiving groove 22, pressing the memory module into the receiving groove 22. When the first spring 211 is in the pressed state, the first clamping cylinder 210 pulls the first clamping head 24, releasing the memory module in the receiving groove 22, thus achieving flexible clamping of the memory module. Camera detection light sources 27 are provided on both sides of the carrier base 21 to illuminate the edges of the memory module. A camera calibration plate 26 is provided at the end of the carrier base 21 for camera positioning and code reading. Product presence sensors 28 are provided on both sides of the carrier base 21. A line adapter interface tool 29 is provided at the end of the carrier base 21 for determining whether the transfer carrier 2 has been displaced into place.

[0062] like Figure 1 , 6 As shown in Figure 7, the flipping mechanism 4 can be raised and lowered to the rear station of the camera detection mechanism 11 and is positioned above the tail end of the second Y-axis linear module 52. After the transfer carrier 2 transfers the memory module to the underside of the flipping mechanism 4, the flipping mechanism 4 descends to flexibly clamp the horizontal memory module and flips it 90 degrees.

[0063] The flipping mechanism 4 includes: a lifting frame 41 controlled by cylinders for lifting and lowering, with cylinders at the four corners of the lifting frame 41 for horizontal lifting and lowering of the entire flipping mechanism 4; a through window 411 for accommodating the transfer carrier 2 on the end face of the lifting frame 41; two sets of mirror-arranged flipping components 42 on the lifting frame 41, and the two sets of flipping components 42 are synchronously displaced relative to each other in the X-axis direction by a drive component; the flipping component 42 includes a width adjustment plate 422, and the width adjustment plate 422 is provided with multiple sets of clamps 424 for clamping the two ends of the memory modules; the number of clamps 424 is the same as the number of memory modules on the transfer carrier 2; the clamps 424 are elastic and rotate synchronously by a drive component.

[0064] The upper end of the lifting frame 41 is fixedly provided with support plates 46 on both sides. The two sets of support plates 46 are rotatably connected to the two ends of each set of support plates 46. The two sets of support plates 46 rotate synchronously through the width adjustment motor 44 and the drive belt 441, which drives the two sets of flipping components 42 to adjust the width synchronously. The width adjustment motor 44 is fixedly installed on the lifting frame 41 and drives one of the support plates 43 to rotate. Through the drive belt 441 and the pulleys at the ends of the two support plates 43, the other support plate 43 is driven to rotate synchronously. The two ends of the width adjustment plate 422 are rotatably connected to the support plates 43 through the support sleeves. When the width adjustment motor 44 drives the support plates 43 to rotate, the two flipping components 42 can be driven to move synchronously relative to each other to achieve width adjustment.

[0065] A flip drive shaft 47 is rotatably provided between the ends of the two sets of support plates 46. The flip drive shaft 47 is connected to the width adjustment plate 422 through a sliding bearing assembly 421. The flip drive shaft 47 rotates through a flip motor 45 and drives multiple sets of clamps 424 to rotate synchronously. The flip drive shaft 47 and the width adjustment plate 422 are connected by transmission through the sliding bearing assembly 421. The sliding bearing assembly 421 can slide on the flip drive shaft 47, and the rotation of the flip drive shaft 47 can drive the sliding bearing assembly 421 to rotate.

[0066] Multiple sets of flip drive gear shafts 423 are rotatably connected side by side to the outer wall of the width adjustment plate 422. The flip drive gear shafts 423 pass through the width adjustment plate 422 and are rotatably connected to the width adjustment plate 422 through bearings. The chuck 424 is set on the inner wall of the width adjustment plate 422. The flip drive gear shafts 423 and the chuck 424 are elastically connected through the second spring connector 425, which is elastic. The spring connector structure includes a sleeve rod and a spring, which can extend and retract and is elastic. The rotation of the flip drive gear shaft 423 can drive the chuck 424 to rotate. The chuck 424 is made of soft rubber and has a slot at the end that is compatible with the memory stick.

[0067] like Figure 7 As shown, the flip drive gear shaft 423 includes two coaxial drive gears. The outer drive gear and the inner drive gear of adjacent flip drive gear shafts 423 are connected by belt drive. The flip drive gear shaft 423 near the sliding bearing assembly 421 is connected to the sliding bearing assembly 421 by belt drive. When the sliding bearing assembly 421 rotates, it drives all flip drive gear shafts 423 to rotate synchronously through the belt, so as to realize the synchronous flipping of the memory module.

[0068] The lifting frame 41 is equipped with a flip position sensor 48 for monitoring whether the memory module is flipped into position, and for detecting whether the memory module is in a 90-degree flipped state.

[0069] like Figure 1 , Figure 4 and Figure 5 As shown, the gripping mechanism 3 achieves X-axis and Y-axis displacement through the first Y-axis linear module 5 and the X-axis lead screw module 51, which is used to flexibly clamp and transfer the memory stick after it has been flipped by the flipping mechanism 4.

[0070] The gripping mechanism 3 includes: a multi-piece spacing adjustment seat 31 that achieves X-axis displacement through 51, and a multi-piece spacing adjustment seat 31 with multiple sets of adjustable spacing lifting flexible gripping mechanisms 32 at the bottom, the lifting flexible gripping mechanism 32 being flat.

[0071] like Figure 5 As shown, the lifting flexible clamping mechanism 32 includes a T-shaped seat 33 located at an adjustable position at the lower end of the multi-piece spacing adjustment seat 31, and a lifting seat 34 that is lifted by a lifting cylinder 35. The bottom of the lifting cylinder 35 is fixedly installed on the top of the T-shaped seat 33, and the output end is connected to the lifting seat 34. A buffer 342 is also provided between the top of the lifting seat 34 and the bottom of the T-shaped seat 33 for buffering.

[0072] The upper end of the lifting seat 34 is provided with two sets of first guide rods 341 that are slidably installed on both sides of the lower end of the T-shaped seat 33 and are slidably connected by linear rails. Two second clamping cylinders 36 are fixed at both ends of the lifting seat 34, and the output end of the second clamping cylinders 36 is elastically connected to the first sliding block 37 through the first spring connector 371. The bottom of the lifting seat 34 is provided with two sets of symmetrically distributed second sliding blocks 38 that are slidably installed by linear rails. The first sliding block 37 and the second sliding block 38 are fixedly connected. The product clamping block 39 is adjustablely installed at the bottom of the second sliding block 38. The bottom of the lifting seat 34 is provided with a limiting plate 310 placed between the two second sliding blocks 38. A second spring 311 is provided between the limiting plate 310 and the two second sliding blocks 38. The bottom of the lifting seat 34 is also provided with a product sensor 312, which is used to detect whether a memory stick is clamped between the two product clamping blocks 39. The product clamping block 39 is made of soft rubber.

[0073] like Figure 1 , Figures 9-11 As shown, the full-disk stacking machine 8 is located at the station behind the flipping mechanism 4 and is used to store the carrier tray 7 that carries the good memory modules. The gripping mechanism 3 clamps the good memory modules flipped by the flipping mechanism 4 into the carrier tray 7 provided in the full-disk stacking machine 8.

[0074] Empty tray stacker 9 is set at the station after the defective product transfer table 10. The empty tray stacker 9 is used to store empty trays 7.

[0075] The suction cup module 6 transfers the tray 7 on the empty tray stacker 9 to the rework transfer plate 101 and the full tray stacker 8.

[0076] The full-disc stacking machine 8 and the empty-disc stacking machine 9 have the same structure, both including a vertical frame 801. The upper end of the vertical frame 801 is provided with a positioning frame 803. Inside the positioning frame 803 is a lifting plate 802 that is lifted and lowered by a Z-axis lifting motor 806. The lifting plate 802 is used to drive the 7 to be lifted.

[0077] The side of the positioning frame 803 is provided with a front and rear positioning component 804 and a left and right positioning component 805 for positioning the carrier plate 7. The front and rear positioning component 804 and the left and right positioning component 805 are all moved by the cylinder to drive the push rod to position the carrier plate 7 on the lifting plate 802.

[0078] The bottom front end of the vertical frame 801 is provided with a receiving platform 807, and a belt conveyor is provided on the receiving platform 807;

[0079] The vertical frame 801 has a Z-axis lifting screw 808 rotating on its back, which is driven to rotate by the Z-axis lifting motor 806. The Z-axis lifting screw 808 has second guide rods 809 on both sides. The rear end of the lifting plate 802 is slidably connected to the second guide rods 809 through a sleeve, and is rotatably connected to the Z-axis lifting screw 808 through the screw sleeve. The Z-axis lifting motor 806 can drive the Z-axis lifting screw 808 to rotate, thereby driving the lifting plate 802 to rise and fall. The upper end of the lifting plate 802 can be equipped with a belt or a motor-driven conveyor roller group for conveying the carrier plate 7 on it to the receiving platform 807.

[0080] like Figure 1 , Figure 8 As shown, the defective product transfer platform 10 is located at the rear station of the full-pan stacking machine 8. The defective product transfer platform 10 is equipped with a rework transfer plate 101, and a tray 7 for carrying rework products is placed on the rework transfer plate 101. The defective product transfer platform 10 is equipped with a defective product inlet 104 for placing defective products, and a collection box is provided at the bottom of the defective product inlet 104.

[0081] The rework transfer plate 101 is slidably mounted on the defective product transfer platform 10, and is displaced along the X-axis direction on the defective product transfer platform 10 by the rework transfer motor 102 and the rework transfer belt 103, so that the carrier tray 7 above can be easily retrieved manually.

[0082] The specific working principle of this invention will be explained in detail below:

[0083] The transfer carrier 2 flows out from the depaneling machine. The first clamping cylinder 210 drives the first clamping head 24. The first clamping head 24 is flush with the edge of the receiving groove 22. The memory module is placed in the receiving groove 22. The air pipe interface 25 connects to the negative pressure system. The negative pressure hole 23 adsorbs the memory module in the receiving groove 22. The first clamping cylinder 210 releases the clamping connecting rod 212. The first spring 211 drives the clamping base 213 and the first clamping head 24 to clamp the memory module in the receiving groove 22. The product sensor 28 detects whether the memory module is in place.

[0084] The second Y-axis linear module 52 moves the transfer carrier 2 to the lower end of the camera detection mechanism 11. The camera detection mechanism 11 uses the camera detection light source 27 and the camera calibration plate 26 to position and photograph the memory module, sequentially detect the size and code of the memory module, determine whether there are problems such as overcutting on the memory module of the transfer carrier 2, mark the memory module on the transfer carrier 2 as good, rework and defective products, and mark its position.

[0085] The second Y-axis linear module 52 transfers the transfer carrier 2 to the lower end of the lifting frame 41. The lifting frame 41 descends via a cylinder. The transfer carrier 2 passes through the window 411. After the sensor detects that the memory module is in place, the lifting frame 41 stops descending. The width adjustment motor 44 drives the two flipping components 42 to approach the edge of the memory module. After the clamp 424 contacts both ends of the memory module, it elastically clamps the memory module through the second spring connector 425. At this time, the negative pressure on the transfer carrier 2 is closed. The first clamping cylinder 210 drives the first clamping head 24 to release the memory module from the clamping state. The transfer carrier 2 returns to the depaneling machine via the second Y-axis linear module 52. The lifting frame 41 rises via a cylinder, and the clamped memory module rises synchronously. The flipping motor 45 drives the flipping drive shaft 47 to rotate. The belt drives the sliding bearing assembly 421 and the flipping drive gear shaft 423 to rotate synchronously, causing the memory module clamped by the clamp 424 to rotate synchronously by 90 degrees. The flipping position sensor 48 detects whether the memory module has been flipped into place.

[0086] The gripping mechanism 3 is displaced by the first Y-axis linear module 5 and the X-axis lead screw module 51. The number of lifting flexible clamping mechanisms 32 is the same as the number of memory modules. The gripping mechanism 3 moves above the flipping mechanism 4, and the lifting cylinder 35 drives the lifting seat 34 to descend. The product sensor 312 senses the position of the memory module. 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 module. Flexible clamping is achieved through the first spring connector 371 and the second spring 311. After clamping, the memory module rises through the lifting cylinder 35. Each clamped memory module is recorded as a good product, a rework product and a defective product by the system.

[0087] Good and rework memory modules are placed onto the trays 7 on the full-disc stacker 8 and the rework transfer plate 101 by the first Y-axis linear module 5 and the X-axis ball screw module 51, respectively, and defective products are collected by the defective product inlet 104.

[0088] The trays 7 on the full-disc stacking machine 8 can be raised and lowered via the lifting plate 802, so the trays 7 can be stacked and the number of layers can be set. When the number of layers is full, they are transferred to the receiving platform 807 via a belt conveyor and then manually removed.

[0089] The trays 7 on the empty tray stacking machine 9 are empty. The stacked empty trays 7 are manually placed into the receiving platform 807 of the empty tray stacking machine 9. The empty and stacked trays 7 are transferred to the lifting plate 802 of the empty tray stacking machine 9 via a belt conveyor. The empty trays 7 are then attracted by the suction cup module 6. The suction cup module 6 is displaced by the first Y-axis linear module 5 and placed on the lifting plate 802 and the rework transfer plate 101 of the full tray stacking machine 8. When the trays 7 on the rework transfer plate 101 are full, the rework transfer motor 102 drives the rework transfer belt 103 to rotate, moving the rework transfer plate 101 to the equipment picking position for manual removal.

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