Description

Technical Field

[0001] The present invention relates to the field of testing and programming, and particularly to a TRAY tray feeding and discharging device. Background Art

[0002] In the field of automated testing and programming, the TRAY tray is an important carrier for transporting chips or electronic modules. The material chips or electronic modules are placed in the slots of the TRAY tray and are driven by a transfer device to be sent to each testing or programming machine station in sequence.

[0003] In the testing or programming process of chips or electronic modules, the testing or programming machine station first removes the chips or electronic modules in the slots of the TRAY tray, then completes the testing or programming on the machine station, and then puts the chips or electronic modules that have completed the testing or programming process back into the TRAY tray slots and sends them out through the TRAY tray. In this process, although the chips or electronic modules are placed in the TRAY tray slots and are grabbed and sent back by the robotic arm of the testing or programming machine station, the movement of the TRAY tray itself along with the transfer device and the feeding position accuracy of the TRAY tray will both affect the testing or programming process, thereby affecting the production efficiency of the product.

[0004] At the same time, in actual production, due to factors such as machine failures, quality control problems of chips or electronic modules, and improper setting of machine parameters, etc., it is impossible to ensure that the pass rate of chips or electronic modules in the testing and programming line is 100%. The existing TRAY tray feeding and discharging device only functions as feeding and discharging in the testing line. Therefore, when production failures occur in chips or electronic modules, it is very difficult to trace the cause of the failure, which has an adverse impact on both the quality control and cost control of chips or electronic modules. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art and to propose a TRAY tray feeding and discharging device.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: It includes a machine body, and two sets of transmission channels are arranged on the machine body, and it is characterized in that: on each set of the transmission channels, there are arranged:

[0007] A feeding area, in which the TRAY tray in the feeding area carries unprocessed chips or electronic modules. The testing or programming machine station group grabs the unprocessed chips or electronic modules from the feeding area through a robotic arm. A first locking device and a second locking device are arranged in the feeding area, and the first locking device and the second locking device keep the position of the TRAY tray sent into the feeding area as an accurate position point.

[0008] A blanking area, where the TRAY trays in the blanking area carry the processed chips or electronic modules. The testing or programming machine sets place the processed chips or electronic modules into the TRAY trays in the blanking area through a robotic arm. A positioning sensor is provided in the blanking area, and the positioning sensor keeps the position where the TRAY tray is sent into the blanking area as an accurate position point;

[0009] An unloading area, which is a storage and unloading area for TRAY trays;

[0010] A set of coding mechanisms is also provided at the upper end of the transmission channel. The coding mechanism is arranged at the upper side of one side of the unloading area, and the coding mechanism is used to code the processed chips or electronic modules.

[0011] Preferably, the coding mechanism includes a transverse movement frame, a transverse movement frame driving device, a coder, and a laser locator. The coder and the laser locator make reciprocating movements on the transverse movement frame through the drive of the transverse movement frame driving device.

[0012] The first locking device and the second locking device are arranged on different sides of the feeding area:

[0013] A conveying mechanism is also provided inside the transmission channel, and the conveying mechanism is used to drive the TRAY tray to move on the transmission channel.

[0014] Multiple groups of material grooves are arranged on the top surface of the TRAY tray, and a clamping groove is provided on the side surface of the TRAY tray.

[0015] A first clamping mechanism is arranged on one side of the blanking area. A first lifting frame and a first lifting frame driving device are provided inside the blanking area, and a limiter is also provided inside the other side of the blanking area.

[0016] A first clamping mechanism, a second lifting frame, and a second lifting frame driving device are provided on the unloading area.

[0022] 2. At the same time, a coding mechanism is provided between the blanking area and the discharging area. The coding mechanism can code and mark the chips or electronic modules.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] Refer to Figure 1-6 , an embodiment provided by the present invention includes a machine platform body 1, and two sets of transmission channels 2 are arranged on the machine platform body 1. It is characterized in that each set of transmission channels 2 is provided with:

[0034] A feeding area 4, where the TRAY tray 3 in the feeding area 4 carries unprocessed chips or electronic modules. The testing or programming machine set grabs the unprocessed chips or electronic modules from the feeding area 4 through a robotic arm. The first locking device 401 and the second locking device 402 are arranged in the feeding area 4, and the first locking device 401 and the second locking device 402 keep the position where the TRAY tray 3 is sent into the feeding area 4 as an accurate position point;

[0035] A blanking area 5, where the TRAY tray 3 in the blanking area 5 carries processed chips or electronic modules. The testing or programming machine set places the processed chips or electronic modules into the TRAY tray 3 in the blanking area 5 through a robotic arm. A positioning sensor 502 is arranged in the blanking area 5, and the positioning sensor 502 keeps the position where the TRAY tray 3 is sent into the blanking area 5 as an accurate position point;

[0036] A discharging area 6, and the discharging area 6 is a storage and discharging area for a TRAY tray 3;

[0037] A set of coding mechanisms 7 is also provided at the upper end of the transmission channel 2. The coding mechanism 7 is provided at the upper end of one side of the discharge area 6. The coding mechanism 7 is used to encode the processed chips or electronic modules.

[0038] In the test and burning line, the tray loading and unloading equipment is used to assist the test or burning machine in loading and unloading materials. In the automated system, the test or burning machine uses an automated robotic arm to pick up and unload materials from the tray 3. Therefore, in production, the feeding position of the tray 3 greatly affects the accuracy of picking or unloading materials. In production, the accuracy of the material is also one of the main problems affecting production efficiency. Based on this production problem, a specialized design of the robotic arm is one direction, but this improvement direction is relatively expensive. Instead, the design of the feeding area 4 and the dropping area 5 ensures that the tray 3 is accurately positioned when it is fed into the feeding area 4 and the dropping area 5, thereby ensuring the gripping accuracy of the robotic arm.

[0039] The coding mechanism 7 includes a transverse frame 701, a transverse frame driving device 702, a coding device 703 and a laser positioner 704. The coding device 703 and the laser positioner 704 are driven by the transverse frame driving device 702 to perform reciprocating motion on the transverse frame 701.

[0040] Through this technical solution, the coding mechanism 7 is set between the blanking area 5 and the discharging area 6. When the TRAY tray 3 moves from the blanking area 5 to the discharging area 6, the coding mechanism 7 can code the chip or electronic module, thereby recording the processing information of the process, which is convenient for tracing the source of the subsequent fault. At the same time, the produced chips or electronic modules are recorded by the coding mechanism 7, and the quality control of the produced chips or electronic modules is better. In this process, the laser locator 704 is used to locate the chip position, making the coding more accurate.

[0041] The first locking device 401 and the second locking device 402 are disposed on different sides of the feeding area 4 .

[0042] Through this technical solution, when the TRAY tray 3 is sent to the preset position of the feed area 4, the first locking device 401 and the second locking device 402 immediately limit and fix the TRAY tray 3, thereby ensuring that the position of the TRAY tray 3 in the feed area 4 is precisely fixed, thereby ensuring that the position of the chip or electronic module is precisely fixed when the robot arm takes the material in the TRAY tray 3, thereby ensuring the feeding accuracy; in this technical solution, the first locking device 401 and the second locking device 402 are equipped with a sensing device, and the first locking device 401 and the second locking device 402 themselves are a fixing device, which can be electrically driven or pneumatically driven to open and close.

[0043] A conveying mechanism is also provided inside the conveying channel 2 , and the conveying mechanism is used to drive the TRAY plate 3 to move on the conveying channel 2 .

[0044] Through this technical solution, the conveying mechanism of the transmission channel 2 is used to drive the TRAY tray 3 to move. After the conveying mechanism sends the TRAY tray 3 into the feeding area 4, the robotic arm removes the chips or electronic modules in the TRAY tray 3 for testing or programming and processing. After all the chips or electronic modules are removed, the empty TRAY tray 3 flows backward into the blanking area 5 to receive the chips or electronic modules after the testing or programming and processing is completed.

[0045] Multiple groups of material slots 302 are arranged on the top surface of the TRAY tray 3, and a card slot 301 is provided on the side surface of the TRAY tray 3.

[0046] Through this technical solution, the material slots 302 are used to place chips or electronic modules. The card slot 301 on the side of the TRAY tray 3 is a specialized design, which cooperates with the first clamping mechanism 503 and the first clamping mechanism 601, enabling the blanking area 5 and the discharging area 6 to have the function of stacking and storing materials.

[0047] A first clamping mechanism 503 is arranged on one side edge of the blanking area 5. A first lifting frame 504 and a first lifting frame driving device 505 are arranged inside the blanking area 5. A limiter 501 is also arranged inside the other side edge of the blanking area 5.

[0048] Through this technical solution, the first clamping mechanism 503 in the blanking area 5 just snaps into the card slot 301 of the TRAY tray 3, thereby clamping and fixing the TRAY tray 3. The first lifting frame 504 can be driven by the first lifting frame driving device 505 to move up and down, so that the TRAY tray 3 can be stacked and stored on the first clamping mechanism 503. The specific process is as follows: When a group of TRAY trays 3 are sent to the blanking area 5, the first lifting frame 504 lifts the TRAY tray 3 to one side of the first clamping mechanism 503. The first clamping mechanism 503 opens and extends into the card slot 301, thereby completing the clamping of a group of TRAY trays 3. After the second group of TRAY trays 3 are sent to the blanking area 5, the first lifting frame 504 continues to lift the TRAY tray 3 to the bottom of the previous lifting frame 504, and then the first clamping mechanism 503 opens until the first lifting frame 504 lifts the bottommost TRAY tray 3 to one side of the first clamping mechanism 503, and then the first clamping mechanism 503 closes and snaps into the card slot 301 of the bottommost TRAY tray 3, while supporting two groups of TRAY trays 3 at the same time. Based on the above steps, the blanking area 5 can stack and store multiple groups of materials. During the lifting process of the TRAY tray 3, the limiter 501 closes to maintain the stability of the TRAY tray 3, ensuring that the chips or electronic modules are stably placed on the TRAY tray 3.

[0049] A first clamping mechanism 601, a second lifting frame 602 and a second lifting frame driving device 603 are arranged on the discharging area 6.

[0050] With this technical solution, the lifting structure in the discharging area 6 is similar to that in the blanking area 5, and multiple groups of TRAY trays 3 can be stacked and stored, thereby alleviating the feeding and discharging pressure of the machine.

[0051] The positioning sensor 502 is electrically connected to an alarm device.

[0052] The positioning sensor 502 monitors the positioning of the TRAY tray 3 in the blanking area 5. When the TRAY tray 3 is accurately positioned, the positioning sensor 502 is normal. When the TRAY tray 3 has a positioning deviation, the positioning sensor 502 senses the information, and the alarm device issues an alarm in a timely manner.

[0053] Both the first lifting frame driving device 505 and the second lifting frame driving device 603 are servo motors.

[0054] A controller 8 is also provided on one side of the machine body 1.

[0055] Working principle: The machine body 1 is provided with a first locking device 401 and a second locking device 402 in the feeding area 4. When the TRAY tray 3 is sent to the preset position in the feeding area 4, the first locking device 401 and the second locking device 402 will limit and fix the TRAY tray 3, so as to ensure that the position where the TRAY tray 3 is sent into the feeding area 4 is an accurate position point. The blanking area 5 is provided with a positioning sensor 501 for monitoring the positioning position of the TRAY tray 3 in the blanking area 5. When the TRAY tray 3 has a positioning deviation, the positioning sensor 502 senses the information, and the alarm device issues an alarm in a timely manner, so as to ensure that the position where the TRAY tray 3 is sent into the blanking area 5 is an accurate position point, thereby ensuring higher accuracy of the robotic arm for picking and placing materials in the testing or programming machine, which is beneficial to reducing production failures and improving production efficiency; at the same time, a coding mechanism 7 is provided between the blanking area 5 and the discharging area 6. The coding mechanism 7 can perform coding and marking on the chips or electronic modules, so as to record the processing information of this process, which is convenient for tracing the source of faults in the later stage. At the same time, by recording the produced chips or electronic modules through the coding mechanism 7, better quality control of the produced chips or electronic modules can be achieved.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
