201119810 六、發明說明： 【發明所屬之技術領域】 本發明係有關於一種自動化夾爪之技術領域，特別是 關於一種用以自動化取放dram模組進行測試之夾爪結構 〇 【先前技術】 在DRAM(動邊隨機存取έ己憶體；Dynamic Random Access Memory)模組的生產線上，DRAM模組必需經過測 試機測試後，才能予以包裝出貨。 而現行DRAM模組的測試工作，大都以人工作業的方 式來進行’從DRAM模組供料盤上取料，再將DRAM模 組插入測試機中進行測試，並由人員目視測試結果，最後 將DRAM模組從測試機中拔取下來，再依測試結果將測試 完成之DRAM模組放入對應的置料盤内。201119810 VI. Description of the Invention: [Technical Field] The present invention relates to the technical field of an automatic gripper, and more particularly to a jaw structure for automated pick and place of a dram module for testing [Prior Art] On the production line of DRAM (Dynamic Random Access Memory) module, the DRAM module must be tested by the test machine before it can be packaged and shipped. Most of the current DRAM module testing work is done manually by taking the material from the DRAM module supply tray, then inserting the DRAM module into the test machine for testing, and the results are visually observed by personnel. The DRAM module is removed from the test machine, and the tested DRAM module is placed in the corresponding storage tray according to the test result.
而測試過後被置入置料盤的DRAM模組則可由自動化 的設備來進行輸送’如我國專利公告第383899號「DRAM 模組取放機」新型專利即是一例，該專利是用於取放經測 試機測試後送出的DRAM模組，其係以一輸送器將DRAM 杈組达至鉤爪處時，由控制器控制鉤爪將組翻轉 ，再藉由控制器以夾爪夾起組放置在放置盒内， 最後則將放滿DRAM模組的放置盒送出。 而DRAM模組測試的卫作目前仍無法以自動化機 具來進行’究其原因’主要是供DRAM模組測試用之插槽 型連接器（Socket)之結構特殊所致。 201119810 請參閱第1圖，其係插槽型連接器插入+DRAM模組 之示意圖。由於該插槽型連接器6之插槽61結構設計，'使 DRAM模組5必需傾斜地插入該插槽61中，然後再將 DRAM模組5向上推正，使插槽型連接器6兩側的彈性卡 - 銷62先被DRAM模組5推開，待DRAM模組5通過後再 復位而阻擋固定該DRAM模組5，使DRAM模組5被固定 於該插槽型連接器6中。 、而要取出該DRAM模組5時，則必需先將兩側的彈性 鲁卡銷62向外推，使DRAM模組5回復到傾斜的狀態，才 能將DRAM模組5取出。 前述的插槽型連接器6的結構，使得DRAM模組5的 取放方式變得複雜，連帶地也使DRAM模組的自動化取放 變得困難。 但為了 k升DRAM模組的測試效率以及測試品質，因 此實有必要研發出一套自動化的DRAM模組測試機構，以 • 符合DARM製造業者的迫切需求。 « 【發明内容】 本發明之主要目的’係在於解決前述各項問題而提供 一種可以取代人工並可與機械人或運動機構連結，以提升 測試效率及測試品質之DRAM模組夾爪。The DRAM module that has been placed in the loading tray after testing can be transported by automated equipment. For example, the new patent of DRAM Module Pick and Place Machine No. 383899 is used for pick and place. After the test machine tests the DRAM module, when the DRAM is assembled to the hook by a conveyor, the controller controls the hook to flip the group, and then the controller is placed in the jaw by the controller. In the box, finally, the placement box filled with the DRAM module is sent out. The DRAM module test is still not able to be automated with the tool. The reason is mainly due to the special structure of the socket type connector (Socket) for DRAM module testing. 201119810 Please refer to Figure 1, which is a schematic diagram of a slot type connector inserted into a +DRAM module. Due to the structural design of the slot 61 of the slot type connector 6, 'the DRAM module 5 must be inserted obliquely into the slot 61, and then the DRAM module 5 is pushed up to the sides of the slot type connector 6. The flexible card - the pin 62 is first pushed away by the DRAM module 5, and after the DRAM module 5 passes through and then resets, the DRAM module 5 is blocked and fixed, so that the DRAM module 5 is fixed in the slot type connector 6. When the DRAM module 5 is to be taken out, the elastic shackles 62 on both sides must be pushed outward to return the DRAM module 5 to the tilted state, so that the DRAM module 5 can be taken out. The structure of the slot type connector 6 described above makes the pick-and-place mode of the DRAM module 5 complicated, and the automatic pick-and-place of the DRAM module is also difficult. However, in order to test the test efficiency and test quality of the k-liter DRAM module, it is necessary to develop an automated DRAM module test mechanism to meet the urgent needs of the DARM manufacturers. « SUMMARY OF THE INVENTION The primary object of the present invention is to provide a DRAM module jaw that can replace the manual and can be coupled with a robot or a motion mechanism to improve test efficiency and test quality.
