Tray is usually used as chip carrier in the semiconductor field, and is used in various chip processing lines. Most of the existing tray loading and unloading devices use fixed positioning columns to position the tray in four directions, which means that manual material placement can only be put in or taken out from above the positioning columns. This method makes it difficult to put in or take out, and increases labor costs. In addition, most of them use manual labor to put the entire tray group with materials into the corresponding loading bin area.

[0057] See also Figures 1 to 5 To achieve the above-mentioned purpose, the present invention provides an adjustable material tray 400 transport and lifting device, including a base plate 100, a conveying assembly and a lifting assembly. Two first slide rails 110 extending in a first direction and parallel to each other are provided on the top of the base plate 100; the conveying assembly is connected to the base plate 100, and the conveying assembly includes two conveying mechanisms spaced apart along the first direction, and the conveying mechanisms each include a loading and unloading mechanism 210 for driving the material tray 400 to move in a second direction, and two feeding mechanisms 220 respectively arranged on both sides of the loading and unloading mechanism 210 and capable of driving the material tray 400 to move in a third direction, and at least one feeding mechanism 220 in the same conveying mechanism is movably connected to the first slide rail 110; there are two lifting assemblies, and the lifting assemblies are connected to the corresponding conveying mechanisms, and the lifting assemblies each include a detection position 310 located above the conveying mechanism and a plurality of lifting plates 320 capable of moving in the second direction, and the lifting plates 320 are used to drive the material tray 400 to move between the detection position 310 and the conveying mechanism;

[0058] After placing the material tray 400 at the loading position, it moves along the second direction behind an loading and unloading mechanism 210 to two feeding mechanisms 220 corresponding to the loading and unloading mechanism 210, and then moves along the third direction to a preset position, and moves along the second direction to the detection position 310 driven by the lifting component to detect and pack the samples in the material tray 400, and then, driven by the lifting component, the material tray 400 with the detected samples moves to another conveying mechanism, and moves to the unloading position driven by the feeding mechanism 220 and the corresponding other loading and unloading mechanism 210, the feeding mechanism 220 and the corresponding other loading and unloading mechanism 210, the material unloading and taking process, the feeding mechanism 220 and the lifting assembly can also operate, which can overcome the disadvantage that the entire tray group with materials can only be placed in the corresponding loading position when the equipment is stopped, thereby improving the sample transportation efficiency; a first slide rail 110 is provided on the top of the base plate 100, and at least one feeding mechanism 220 in the same conveying mechanism is movably connected to the first slide rail 110, and the distance between the two feeding mechanisms 220 in the same conveying mechanism can be adjusted, which is suitable for material trays 400 of various sizes, and can overcome the problem that the tray loading and unloading device in the prior art has poor compatibility with the size of the incoming tray.

[0059] In this embodiment, a conveying mechanism and a lifting component are used as a loading module, which are used to transport the Tray chopping group from the loading position to the detection position 310, and another conveying mechanism and another lifting component are used as an unloading module, which are used to transport the Tray chopping group from the detection position 310 to the unloading position. Specifically, the loading and unloading mechanism 210 of the loading module transports the Tray chopping group at the loading position to position A (the first position), and then the feeding mechanism 220 of the loading module transports the Tray chopping group at position A to position B (the second position), and then moves to position C (the third position) of the detection position 310 driven by the lifting component of the loading module. Under the action of the manipulator, the DIE semi-finished product material in the loading Tray group is transported to the test platform for testing, and the manipulator then transfers the DIE material on the test platform to the Tray at position D of the detection position 310 according to the test results. In the y tray, the external manipulator repeatedly takes DIE material from the Tray at position C for testing on the test platform, and transfers the DIE material on the test platform to the Tray at position D of the detection position 310 according to the test results until the material hole in the Tray at position D is filled with DIE material, and the lifting component of the unloading module (supporting the Tray at position D) descends by a Tray thickness displacement value, and at the same time, the external manipulator absorbs the empty Tray on the detection position 310 to position D, and repeats the above action flow. When the Tray chopping group at position D is accumulated to a certain thickness, it is transferred from position D to position E under the drive of the lifting component of the unloading module, and then transferred to position F under the drive of the feeding mechanism 220 of the unloading module, and then the loading and unloading mechanism 210 of the unloading module lifts the Tray chopping group at position F to the unloading position for unloading.

[0060] Among them, it should be noted that, according to the number of lifting plates 320 in the lifting component of the loading module, the detection position 310 can be divided into C1, C2, C3, C4, C5, etc., and similarly, according to the number of lifting plates 320 in the lifting component of the unloading module, the detection position 310 can be divided into D1, D2, D3, D4, D5, etc., and taking the number of lifting plates 320 in the loading module and the unloading module as three as an example, C1 and C2 can be used as the placement position of the Tray plate chopping group loaded with the products to be detected, C3 can be used for the placement position of the empty Tray plate chopping group, and D1, D2, and D3 are respectively used as placement positions corresponding to the three detection results. The three empty trays on C3 can be placed on D1, D2, and D3 respectively by the robot. Then the robot drives the DIE materials on C1 and C2 to the test platform for testing and places them in one of D1, D2, and D3 according to the test results. This process is repeated continuously. When empty trays appear on C1 and C2, the empty trays are transferred to C3 by the robot. When the trays of D1, D2, and D3 are full, the empty trays of C3 are adsorbed by the robot to replenish the trays.

The conveying mechanisms also include a third power source 230 and a transmission shaft 240. The third power source 230 can be a motor and fixed to the track plate 221. The transmission shaft 240 is connected to the output end of the third power source 230.

The tray guide block 213 can be replaced according to the size and structure of the Tray, so as to achieve the above purpose.

One way is to manually move the Tray group to the loading position, and then move it away when the Tray group materials are sent out from the unloading position. The other way is to connect with other external processes. Both loading and unloading of the Tray are achieved by a truss robot. The loading and unloading mechanism 210 can be set at the same end of the conveying mechanism in the third direction, so as to facilitate connection with the previous and next processes to realize the automatic connection function of the equipment.

The rods 522 are respectively penetrated through the corresponding support plates 224, and the synchronous rotation of the two groups of second lead screws 522 is realized through the conveyor belt and the pulley connected to the second lead screw 522. The two lead screws are driven to rotate synchronously by a second power source 521, so that the support plate 224 connected to the corresponding second lead screw 522 is moved along the extension direction of the first slide rail 110, so as to adjust the distance between the two feeding mechanisms 220 in the same group of conveying mechanisms, wherein, while the feeding mechanism 220 moves relatively, the third plate body 324 is also driven by the second support rod 350 to move relative to the second plate body 323 along the extension direction of the second slide rail 322.

[0071] In addition, a handwheel 524 is connected to the end of the second lead screw 522 facing away from the second power source 521. The handwheel 524 can drive the second lead screw 522 to rotate around its own axis, and can also realize the position adjustment of the feeding mechanism 220 on the first slide rail 110. The first rail is also provided with a supporting width adjustment slider fixing block for fixing the slider located at the bottom of the support plate 224. At the same time, the feeding mechanism 220 that can slide relative to the first rail is provided with a drag chain for moving and traction of the feeding mechanism 220. An origin switch can be set on the first rail, and a rail sensor sheet is set on the support plate 224 for obtaining the position of the feeding mechanism 220 on the first rail. The first rail is also provided with a rail sensor locking block for ensuring the safety and stability of the rail operation, which can trigger braking under specific circumstances to prevent accidents.

[0072] In summary, the adjustable tray 400 transport and lifting device provided in the present application, a conveying mechanism and a lifting component as a loading module, used for conveying the Tray chopping group from the loading position to the detection position 310, another conveying mechanism and another lifting component as a unloading module, used for conveying the Tray chopping group from the detection position 310 to the unloading position, and the conveying step specifically includes the following steps.

[0073] Step 1: Place the whole stack of Tray chops in the loading and unloading mechanism 210 at the front end of the loading module. Under the action of the lifting cylinder 212, the whole stack of Tray chops can be lowered onto the conveyor belt 223 of the conveying mechanism. Under the action of the third power source 230, the whole stack of Tray chops is transported backwards.

[0074] Step 2: The lifting plate 320 enters the corresponding waiting position under the action of the first power source 361 and waits until the entire stack of Tray plates moves to the waiting position and blocks the entire stack of Tray plates under the action of the loading block. After the loading sensor installed on the loading block senses a signal, the first power source 361 is started, and under the action of the first screw rod and the first screw nut 363, the Tray plates are driven to move upward, so that the Tray plates are separated from the conveyor belt 223.

[0075] Step 3: Repeat the operations of steps 1 and 2 to achieve the lifting of the loaded tray group and the empty tray group to the detection position 310, so that the detection position 310 has two groups of fully loaded trays and one group of empty trays;

[0076] Step 4: Take the empty tray from the loading area in step 3 and place it in the detection position 310 in the unloading module. It can be divided into three categories according to actual conditions. After the external robot classifies the finished materials according to the system, it will be unloaded into the tray corresponding to the detection position 310;

[0077] Step 5: Repeat the operations of step 3 and step 4 to complete the detection and material separation. When the number of trays at the detection position 310 in the unloading module reaches the set value, the system will give a signal. Under the action of the motor, the tray will move downward. When the system gives the unloading signal, the conveyor belt 223 in the unloading module will be stationary.

[0078] Step 5: When the first power source 361 drives the Tray to move downward to the conveyor belt 223, the third power source 230 for driving the conveyor belt 223 will reverse, and under the action of static friction, the Tray will be driven to be transferred to the front loading and unloading mechanism 210 along with the conveyor belt 223;

[0079] Step 6: The loading and unloading mechanism 210 in the unloading module, under the lifting action of its lifting cylinder 212, lifts up the unloading tray assembly, so that the tray assembly is separated from the conveyor belt 223, thus completing a complete unloading.

[0080] The adjustable material tray 400 transport and lifting device is provided with two conveying mechanisms, and a tray loading and unloading mechanism 210 is provided at the front end of the two conveying mechanisms, and the lifting component is embedded in the middle of the two feeding mechanisms 220 of the conveying mechanism, so as to achieve the effect of vibration-free lifting by directly driving the first screw 362 through the first power source 361 through the tray group on the conveyor belt 223 to reduce the shaking of the wafer DIE in the tray group with material and cause the rollover. At the same time, the two groups of conveying mechanisms can meet the adjustment function of the device to adapt to two different specifications of IC wafer trays of 4in and 5in through the distance adjustment mechanism, so as to realize the automatic loading and unloading of the tray without stopping in the existing wafer DIE test and the automatic line production of the tray groups of different sizes to improve the flexibility and production efficiency of the equipment.
