Description

Technical Field

[0001] This utility model relates to a material supply and receiving device and a transfer device, and more particularly to a material supply and receiving device and a transfer device for providing materials to be processed or for receiving and transporting finished products after processing, which is used as a processing host. Background Technology

[0002] In general loading and unloading equipment applications, in addition to being set at one or both ends of a processing host to provide materials to be processed or to store finished products after processing, in advanced semiconductor packaging processes, such loading and unloading equipment also has the function of receiving or grabbing material boxes transported from the overhead crane system.

[0003] The feeding and receiving equipment typically uses a gripping unit of a transfer device to grip the material box conveyed by the overhead crane system and transfer it to a material rack. The gripping unit then grips the material box on the material rack, and a pusher rod of a pushing device pushes the trays containing the workpieces to be processed in the material box one by one to a rail frame. The rail frame then transports the trays to a processing host for processing.

[0004] In the prior art of the feeding and receiving equipment, the material boxes transported by the overhead crane system often have multiple different specifications to store different trays. Although the unloading point of the material box on the overhead crane system is preset, errors are still difficult to avoid. On the other hand, as the multi-tasking requirements of the processing machine are gradually being considered, the same feeding and receiving equipment may need to store multiple different specifications of the material boxes at the same time. Therefore, how to prevent the gripping unit of the transfer device from making errors during gripping has become a subject that must be studied and improved. Utility Model Content

The base F334 and the winding belt F336 are fixedly connected. The slide F332 is driven by a driven screw F339 and can move back and forth along a second axis Y. During this movement, the winding belt F337, the latching member F334, and the support F335 on it are also moved back and forth.The latching member F336 has rollers F34 on both sides, which can move up and down synchronously with the latching member F336. Each roller F34 is located at one end of a swing arm F342 pivotally mounted on a pivot F341. The other end of the swing arm F342 is acted upon by a spring-loaded elastic element F343, causing the swing arm F342 to experience an elastic restoring force when it swings. When the second pick-and-place mechanism F3 clamps the material box B, the rollers F34 push against the upper surface of the upper frame B3 of the material box B and the upper flange B4 on one side.

[0110] Please see Figure 1 When the feeding and receiving equipment is located at the inlet end of the processing host, the material box B placed by the operator can be received by the platform E1 of the loading device E, or the material box B from the conveying system C can be received by the first pick-and-place mechanism F2 of the transfer device F; wherein,

[0111] Please see Figure 3 , 4 6. After the platform E1 of the loading device E receives the material box B placed by the operator, if it is necessary to adjust its position, the platform E1 can be rotated to the preset position by the linkage E341 engaging with the rotating seat E11. If there is no need for rotation adjustment, the linkage E341 disengages from the rotating seat E11, and the locking member E13 locks into the bottom of the platform E1. The driving member E3 of the lifting seat E3... 3. The drive screw E32 causes the nut seat E321 to move the extension seat E4 along the track E31 toward one side of the hopper D. The movement of the winding belt E35 causes the fixing member E111 to move the rotating seat E11 and the platform E1 on it, moving the platform E1 into the moving section D117 between the two side frames D115 of the first frame D11 in the hopper D. The material box B placed on the platform E1 is then... Figure 9 The material box B is fed into the positioning seats D116 on the two side frames D115 below the front box space D111, so that the material box B is positioned there. Then, it is moved to the position below the material box B in the front box space D111 by the transfer table D143 in the transfer space D14, and the material box B is carried by the top and moved through the moving section D117. The material box B is transported and placed on the positioning seats D116 on the two side frames D115 below the rear box space D112. Then, it is picked up by the second pick-and-place mechanism F3 of the transfer device F, and pushed by the push rod H1 of the push device H against the tray B1 in the material box B to the flow channel G2 of the discharge device G, so as to be sent to the processing host for processing.

[0112] After the first pick-and-place mechanism F2 of the transfer device F receives the material box B from the conveying system C, it places the material box B on the positioning seat D132 of the platform D131 of the third rack D13. The orientation of the material box B is adjusted by the driven rotation of the platform D131. The first pick-and-place mechanism F2 then lifts the material box B from the platform D131 and places it on the positioning seats D126 of the two side frames D125 below the box space D122 of the second rack D12. The material box B is then carried by the transfer platform D153 through the moving section D127, and placed on the positioning seats D126 of the two side frames D125 below the box space D121. Then, the lifting seat E3 of the loading device E rises from the rail seat E2 to the platform E1 corresponding to the second rack D12. The lifting seat E3 drives the screw E32 via the drive member E33, causing the nut seat E321 to move the extension seat E4 on the track E31 toward one side of the hopper D. The movement of the winding belt E35 causes the fixing member E111 to move the rotating seat E11 and the platform E1 on it, so that the platform E1 moves into the moving section D127 between the two side frames D125 in the second frame D12 of the hopper D. The platform E1 is lifted and moved out of the box B in the box space D121. Then the lifting seat E3 descends from the track seat E2 to the platform E1 corresponding to the first frame D12. The platform E1 is then transported in the first frame D12 by the aforementioned loading device E, so that the tray B1 in the box B is pushed against the flow channel G2 of the discharge device G and sent to the processing host for processing.

[0113] When the receiving and receiving equipment is located at the discharge end of the processing host, the various mechanisms will only change in direction and position, with the left and right sides reversed. The mechanism and operating principle are the same. The discharge device G receives the tray B1 carrying the finished product sent out by the processing host through the flow channel G2 and enters the material box B. The second pick-and-place mechanism F3 then picks up the material box B and sends it to the silo D. The process is then reversed and carried out to the conveying system C for transfer to other processing hosts or to the platform E1 for operators to pick up.

[0114] Please see Figure 10 , 11-12, the back seat F237 of the first pick-and-place mechanism F2 of the transfer device F is provided with a box end detection unit F25. The box end detection unit F25 has a first sensing group F251 consisting of two sensors F2511 arranged horizontally and spaced apart along the first axis X, and a second sensing group F252 consisting of two sensors F2521 arranged horizontally and spaced apart. The horizontal distance between the two sensors F2511 in the first sensing group F251 is greater than that between the two sensors F2521 in the second sensing group F252. The horizontal spacing between the two sensors F2521 is such that the first sensing group F251 is located above the second sensing group F252. Both the first sensing group F251 and the second sensing group F252 are contact proximity sensors of the reed switch type, and their sensing direction is towards the support area F24. They detect the width of the end of the cassette B with the opening B2 placed in the support area F24. The first sensing group F251 detects the cassette B with the larger opening B2 end width, and the second sensing group F252 detects the cassette B with the smaller opening B2 end width.

[0115] Please see Figure 10 , 13 The first pick-and-place mechanism F2 of the transfer device F has a back seat F237 on both sides, which are horizontally aligned with the first axis X and spaced apart, forming a box-side detection unit F26 consisting of two sensors F261. The horizontal distance between the two sensors F261 in the box-side detection unit F26 is greater than the horizontal distance between the two sensors F2511 in the first sensing group F251 of the box end detection unit F25. Each of the two sensors F261 in the box-side detection unit F26 is a reflective line laser sensor, which can detect the width of the side of the material box B without the opening B2 in the support area F24.

[0116] Please see Figure 10 , 14 The transfer device F has a tab detection unit F27 on both sides of the first pick-and-place mechanism F2. The tab detection unit F27 includes a first sensing unit F271 consisting of two sensors F2711 located on both sides of the latch F236, horizontally corresponding to each other along the first axial direction X and spaced apart, and a second sensing unit F272 consisting of two sensors F2721 located on both sides of the lifting platform F23, with a spaced distance corresponding to the area below the first sensing unit F271. The horizontal distance between the two sensors F2711 of the first sensing unit F271 or the two sensors F2721 of the second sensing unit F272 is greater than the width of the material box B without an opening B2. Figure 11 , 12The width of each side is a corresponding sensor. When the slide F232 is driven and the support F235 is moved forward along the second axis Y to the first sensing unit F271 corresponding to the second sensing unit F272 below, that is, when the cassette B is picked up into the support area F24, the sensor detects the protrusion B5 (e.g., the tray carried in the cassette B) that extends out of the cassette B with the opening B2 end due to the conveying process.

[0117] Please see Figure 10 , 15 The back seat F237 of the first pick-and-place mechanism F2 of the transfer device F is provided with a box detection unit F28 consisting of two sensors F281 arranged horizontally and at intervals along the first axis X. Each of the two sensors F281 in the box detection unit F28 is a reflective line laser sensor, with two parallel line laser beams F282 pointing towards the conveying system C along the second axis Y. This allows for the detection of the box B still placed on the conveyor frame C2 after being transported by the conveying system C, thus confirming the arrival of the box. Specifications of cassette B; wherein, each of the two sensors F281 is driven by a drive member F283, such as a sliding pneumatic cylinder, and can move between a first positioning F284 that is close to each other and a second positioning F285 that is far apart from each other. When the two sensors F281 are in the first positioning F284, they detect the end of cassette B on the conveyor C2 that has an opening B2. When the two sensors F281 are in the second positioning F285, they detect the side of cassette B on the conveyor C2 that does not have an opening B2.

[0118] This utility model provides a receiving device and a transfer device. Since the material box B transported by the first pick-and-place mechanism F2 of the transfer device F can be detected and confirmed, incorrect pick-and-place operations can be avoided, and the material box B can be transported efficiently and correctly.

[0119] However, the above description is only a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made based on the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
