Description

Technical Field

[0001] The present invention relates to a system and method for correcting the position degree of an intelligent socket, belonging to the technical field of position correction in the automated production of intelligent sockets. Background Art

[0002] An intelligent socket is a constituent mechanism for realizing operations such as assembly, testing, and programming of semiconductor component workstations. During the process of semiconductor component operations, it carries the semiconductor components to ensure the precise position degree of the semiconductor components, thereby realizing the docking and alignment of the workstations and the pick-and-place transfer of the alignment.

[0003] Generally, an intelligent socket is mounted on a workstation device. The workstation device includes a workstation base and a turnover mechanism arranged on the top of the workstation base. The workstation base is provided with a detachable workstation carrier. A number of intelligent sockets are arranged on the workstation carrier, and the batch loading requirements of semiconductor components are met by the number of intelligent sockets carried by the workstation carrier.

[0004] During the operation of the device, the requirement for the position accuracy of semiconductor components is relatively high. Especially during batch picking and turnover, rapid and precise positioning can improve the operation efficiency, and at the same time reduce the occurrence of situations such as material retention caused by position degree deviation or material dropping caused by picking deviation.

[0005] In the prior art, there are position degree deviations when the intelligent socket is assembled with the workstation carrier. At the same time, when the intelligent socket is on the workstation, the pressing force will also cause a certain degree of deformation and position degree deviation, resulting in the loading chamber of the intelligent socket being unable to meet the loading accuracy of semiconductor components. Therefore, in traditional devices, a vision detection mechanism is designed on the turnover mechanism. During the operation, after collecting the position degrees of a number of intelligent sockets on the workstation base, the corresponding docking coordinates are generated to meet the docking requirements after accurate position degree recognition.

[0006] However, the workstation device has frequent material turnover. The traditional vision detection mechanism has relatively cumbersome operations, and there is a long operation and positioning response time for each turnover, which affects the operation efficiency of the device. Summary of the Invention

[0007] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art. Aiming at the problem that the traditional intelligent socket has a position degree deviation, resulting in a long response time for position degree determination and affecting the efficiency, the present invention proposes a system and method for correcting the position degree of an intelligent socket.

[0008] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows: An intelligent socket position correction system is provided on a workstation device. The workstation device includes a workstation base and a turnover mechanism arranged on the top of the workstation base. The workstation base includes a workstation carrier, and a number of intelligent sockets are provided on the workstation carrier. The intelligent socket includes a circuit board and a carrier base body with a loading cavity arranged on the circuit board. A position degree memory is provided on the circuit board; The turnover mechanism is provided with a vision detection mechanism and a controller respectively communicatively connected with the position degree memory and the vision detection mechanism.

[0009] Preferably, a reading and writing module for reading and writing the position degree memory is provided in the controller, and an update module communicatively connected with the reading and writing module and the vision detection mechanism respectively.

[0010] Preferably, a loading position for detachably carrying the intelligent socket one by one is provided on the workstation carrier, and an anti-misoperation mechanism is arranged between the loading position and the corresponding intelligent socket.

[0011] Preferably, the anti-misoperation mechanism includes two positioning through holes arranged on the circuit board and positioning pin columns arranged on the loading position corresponding to the positioning through holes one by one.

[0012] Preferably, the workstation carrier is detachably arranged on the workstation base, and a positioning and matching mechanism is arranged between the workstation carrier and the workstation base.

[0013] Preferably, the positioning and matching mechanism includes a number of positioning grooves arranged on the workstation base and positioning matching blocks arranged at the bottom of the workstation carrier corresponding to the positioning grooves one by one.

[0014] The present invention also proposes a correction method for an intelligent socket position correction system, including the following steps: S1 Initial calibration: After the intelligent socket is formed, the position degree deviation data of the loading chamber relative to the circuit board is obtained through a calibration device and stored in the position degree memory; S2 Turnover correction: The controller reads the position degree deviation data in the position degree memory and performs displacement compensation correction of the turnover mechanism; S3 Deviation data update: The vision detection mechanism performs relative position degree detection of the loading chamber and obtains position degree update data, and the controller receives the position degree update data to update the data in the position degree memory.

[0015] Preferably, a reading and writing module for reading and writing the position degree memory is provided in the controller, and an update module communicatively connected with the reading and writing module and the vision detection mechanism respectively; In step S3, the update module triggers the detection operation of the vision detection mechanism, and the reading and writing module writes the latest obtained position degree update data into the position degree memory.

[0016] Preferably, in step S1, the position degree deviation data includes horizontal plane deviation coordinates; In step S3, a deviation update threshold is set. Through the historical data of the position degree deviation data, the corresponding relationship between the deviation amounts in the two coordinate directions of the horizontal plane deviation coordinates and the number of workstation operations is calculated, and the number of workstation operations threshold corresponding to reaching the deviation update threshold is obtained, and the number of workstation operations threshold is used as the trigger condition for the update module.

[0017] The beneficial effects of the present invention are mainly reflected in: 1. It can realize the recording of the deviation position degree of the smart socket. Without frequent visual guidance, it can directly perform the compensation operation after reading the deviation, and the equipment runs efficiently and smoothly.

[0018] 2. It meets the periodic update requirements, ensures that the deviation data matches the actual situation, and maintains the long-term reliable operation of the equipment.

[0019] 3. The design of the workstation carrier and the smart socket improves the operation rate of the workstation equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] The following further describes the present application in detail in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the sake of description, only the parts related to the relevant invention are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] The present invention provides an intelligent socket position correction system, as Figures 1 to 4 shown, which is set on the workstation device 1. The workstation device 1 includes a workstation base 2 and a turnover mechanism 3 provided on the top of the workstation base 2. The workstation base 2 includes a workstation platform 4.

[0027] A number of intelligent sockets 5 are provided on the workstation platform 4. The intelligent socket 5 includes a circuit board 51 and a carrier base body 6 provided on the circuit board 51 and having a loading cavity 60. A position degree memory 52 is provided on the circuit board 51.

[0028] The turnover mechanism 3 is provided with a visual detection mechanism 30 and a controller respectively communicatively connected to the position degree memory and the visual detection mechanism.

[0029] Specific implementation process and principle description: The traditional intelligent socket 5 is integrated on the workstation platform 4. When the intelligent socket 5 is processed and assembled with the workstation platform 4, the position degree of the carrier base body 6 will be offset. In addition, the workstation platform 4 is also used in a long-term cycle, and there will also be accumulated deformation during use, resulting in the position degree offset of the carrier base body 6.

[0030] In this case, the design of the position degree memory 52 on the circuit board 51 is adopted. The position degree memory 52 can store the position degree deviation data of the carrier base body 6 on the current intelligent socket 5. The position degree memory 52 can be an IC chip, which can be equipped with a radio frequency interaction module or can communicate with the controller after being electrically connected to the workstation base 2.

[0031] After the controller can read the positional tolerance deviation data, deviation compensation for the picking and placing drive of the turnover mechanism 3 can be achieved, thus eliminating the response time for visual acquisition and calculation of the position, significantly improving the operating efficiency of the device, and preventing problems such as material retention caused by docking deviation or material dropping during the turnover process.

[0032] In addition, the vision detection mechanism 30 can perform on-line positional tolerance detection, so as to meet the requirement for correcting the positional tolerance deviation data in the positional tolerance memory 52.

[0033] In a specific embodiment, the controller is provided with a reading and writing module for reading and writing the positional tolerance memory, and an update module respectively communicatively connected to the reading and writing module and the vision detection mechanism.

[0034] Specifically, generally, the positional tolerance deviation data in the positional tolerance memory 52 can meet its certain effective time, and periodic or threshold triggering can be set. At this time, the update module updates the data according to the trigger, and its transmission instruction value is sent to the vision detection mechanism 30 for positional tolerance detection, and the obtained updated data is written and updated to the positional tolerance memory 52 by the reading and writing module.

[0035] In a specific embodiment, the workstation carrier 4 is provided with mounting positions for detachably mounting intelligent sockets one by one, and an anti-fooling mechanism 7 is provided between the mounting positions and the corresponding intelligent sockets.

[0036] Specifically, the intelligent sockets are recycled. When a failure or other situation occurs, individual replacement of the intelligent sockets is required. Through the anti-fooling mechanism 7, its directional mounting can be ensured, so as to ensure the validity of the data in its positional tolerance memory 52.

[0037] In a specific embodiment, the anti-fooling mechanism 7 includes two positioning through holes 71 provided on the circuit board, positioning pin columns 72 provided on the mounting positions corresponding to the positioning through holes one by one, and a support position 73 provided at one end of the mounting position.

[0038] That is, reliable positioning is ensured through the positioning through holes and the positioning pin columns. In addition, the support position 73 realizes anti-fooling orientation.

[0039] In a specific embodiment, the workstation carrier 4 is detachably arranged on the workstation base, and a positioning and mating mechanism 8 is provided between the workstation carrier and the workstation base.

[0040] Specifically, the workstation device 1 includes multiple cooperating workstation bases 2. Through the detachable design of the workstation carrier 4, the equipment changeover and operation requirements are met. And the positioning and mating mechanism 8 can meet the mounting limit of the workstation carrier 4.

[0041] In a specific embodiment, the positioning and mating mechanism 8 includes a plurality of positioning grooves 81 provided on the base of the workstation and positioning mating blocks 82 provided at the bottom of the workstation stage and corresponding to the positioning grooves one by one.

[0042] In this way, the positioning and mounting requirements are met. Of course, other structures for achieving precise positioning are also within the protection scope of this case.

[0043] The correction method of an intelligent socket position degree correction system in this case will be described in detail: Initial calibration: After the intelligent socket is formed, the position degree deviation data of the loading chamber relative to the circuit board is obtained by the calibration device and stored in the position degree memory.

[0044] Turnover correction: The controller reads the position degree deviation data in the position degree memory and performs displacement compensation correction on the turnover mechanism.

[0045] Deviation data update: The vision detection mechanism performs relative position degree detection on the loading chamber and obtains position degree update data. The controller receives the position degree update data and updates the data in the position degree memory.

[0046] Specifically, after the intelligent socket is manufactured and formed, the position degree deviation of its loading chamber can be detected by the calibration device, and the position degree deviation data is written into the position degree memory. In this way, it can be directly used after the intelligent socket is assembled.

[0047] The controller can read the original position degree memory for direct use.

[0048] After running for a period of time, the position degree can be detected by the vision detection mechanism to obtain position degree update data, and thus the data in the position degree memory is updated.

[0049] Each time the device runs, there is no need for the vision detection mechanism to guide. Only by reading the position degree data can the precise and efficient operation after displacement compensation correction be satisfied.

[0050] In a specific embodiment, the update module triggers the detection operation of the vision detection mechanism, and the reading and writing module writes the latest obtained position degree update data into the position degree memory.

[0051] Through the design of the update module, automatic triggering of updates can be achieved, eliminating the situation of missed manual triggering and maintaining the reliable long-term operation of the device.

[0052] In a preferred embodiment, the position degree deviation data includes horizontal plane deviation coordinates.

[0053] Set a deviation update threshold. Based on the historical data of the positional tolerance deviation data, calculate the corresponding relationship between the deviation amounts in the two coordinate directions of the horizontal plane deviation coordinates and the number of workstation operations, and obtain the threshold of the number of workstation operations corresponding to reaching the deviation update threshold. Use the threshold of the number of workstation operations as the trigger condition for the update module.

[0054] Specifically, the positional tolerance deviation data is generally the deviation within a plane, usually the two-axis coordinates of the X-axis and Y-axis directions. The illustrations of the X-axis and Y-axis are omitted in the attached drawings. The X-axis and Y-axis coordinate systems within the plane are prior art and will not be elaborated here.

[0055] In this case, the number of workstation operations and the deviation amounts of the X-axis and Y-axis are used for calculation. For example: when the workstation operates 50 times, the cumulative deviation amount of the X-axis is 0.25 mm, and the cumulative deviation amount of the Y-axis is 0.15 mm. At this time, the set threshold is 0.25 mm. That is, when the number of operations of the equipment workstation reaches 50 times, the update operation is automatically performed. This data is subject to actual operation. Generally, the set range of the deviation update threshold is between 0.01 mm and 0.3 mm, and the initial number of workstation operations for update is 10 - 50 times. After the equipment operates at least three update cycles, the fixed threshold of the number of workstation operations is determined.

[0056] From the above description, it can be found that it is possible to record the deviation positional tolerance of the smart socket. There is no need for frequent visual guidance, and the compensation operation can be directly performed after reading the deviation, making the equipment operate efficiently and smoothly. It meets the periodic update requirements, ensures that the deviation data matches the actual situation, and maintains the long-term reliable operation of the equipment. The design of the workstation carrier and the smart socket improves the utilization rate of the workstation equipment.

[0057] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, so that a process, method, article, or equipment / device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes the elements inherent in these processes, methods, articles, or equipment / device.

[0058] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the attached drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
