Description

Technical Field

[0001] This application relates to the field of semiconductor testing technology, and in particular to a transfer device and a test sorting machine. Background Technology

[0002] In semiconductor manufacturing and good product management processes, semiconductor devices that have undergone specified manufacturing processes must be tested for performance and parameters using a testing instrument. A test sorter is used to move the devices under test to the interface position of the testing instrument for electrical connection. During operation, the pre-processing chamber of the test sorter contains multiple trays arranged sequentially along their thickness direction. The transfer device of the test sorter stores these trays and simultaneously moves them synchronously along their arrangement direction, sequentially moving each tray to the target station.

[0003] In related technologies, the transfer device of a test sorting machine mainly consists of a clamping and moving mechanism and a positioning and supporting mechanism. The upper and lower support plates of the positioning and supporting mechanism can simultaneously clamp multiple trays facing each other. When it is necessary to move the trays, firstly, the clamping and moving mechanism clamps multiple trays simultaneously; then, the upper and lower support plates move away from each other to release the trays. Subsequently, the clamping mechanism moves the multiple trays to the next station. Then, the upper and lower support plates of the positioning and supporting mechanism move towards each other again to re-clamp and position the trays. This cycle repeats.

[0004] The transfer device of the related technology requires the cooperation of a support mechanism and a clamping and moving mechanism to complete the storage and movement of the material tray. It is not only complex in structure, but also has cumbersome in operation, resulting in low overall work efficiency. Utility Model Content

[0019] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0020] Please see Figures 1-4The transfer device 100 includes a support 1, a screw conveying mechanism 2, a drive mechanism 3, a first limiting rod 4, and a second limiting rod 5. The screw conveying mechanism 2, drive mechanism 3, first limiting rod 4, and second limiting rod 5 are disposed on the support 1. The screw conveying mechanism 2 is used to hold multiple material trays A. The screw conveying mechanism 2 includes a first conveying screw 21, a second conveying screw 22, and a third conveying screw 23 extending along a first direction X and disposed on the support 1. The first conveying screw 21 and the second conveying screw 22 are disposed opposite each other along a second direction Y. The third conveying screw 23 and the first conveying screw 21 are arranged sequentially along a third direction Z. The threaded groove b1 of the first conveying screw 21 and the threaded groove b2 of the second conveying screw 22 are used to hold two protrusions a at the bottom end A2 of the material tray A, respectively. The threaded groove of the third conveying screw 23 is used to abut against a protrusion a at the top corner A1 of the material tray A. The drive mechanism 3 is connected to the first conveying screw 21, the second conveying screw 22, and the third conveying screw 23. The drive mechanism 3 drives the first conveying screw 21, the second conveying screw 22, and the third conveying screw 23 to rotate synchronously in the same direction, thereby moving the material tray A along the first direction X. The first limiting rod 4 and the second limiting rod 5 both extend along the first direction X, and are used to abut against the opposite two side edges of the material tray A, respectively. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0021] When applied to the test sorting machine 1000, the first direction X is parallel to the arrangement direction of the multiple material trays A, and the third direction Z is the same as the direction of gravity. The material trays A include opposing top ends A1 and bottom ends A2, and opposing first side ends A3 and second side ends A4. When the material trays A are in a vertical state, top ends A1 and bottom ends A2 are arranged along the direction of gravity, and first side ends A3 and second side ends A4 are arranged sequentially along the second direction Y. Two protrusions a are provided at the edge of the bottom end A2, arranged along the second direction Y. A protrusion a is also provided at the corner where top end A1 meets first side end A3 and / or at the corner where top end A1 meets second side end A4. For ease of description, the two protrusions a arranged sequentially along the second direction Y at the bottom A2 are referred to as the first protrusion a1 and the second protrusion a2, respectively. The protrusion a at the corner where the top A1 and the first side A3 meet is referred to as the third protrusion a3, and the protrusion a at the corner where the top A1 and the second side A4 meet is referred to as the fourth protrusion a4. Multiple threaded grooves b1 on the first conveying screw 21, multiple threaded grooves b2 on the second conveying screw 22, and multiple threaded grooves b3 on the third conveying screw 23 can respectively hold multiple vertically placed trays A arranged sequentially along the first direction X. The first limiting rod 4 and the second limiting rod 5 abut against the opposite first side edge A3 and second side edge A4 of the multiple trays A, respectively. Thus, multiple trays A can be stored on the screw conveying mechanism 2. When it is necessary to move multiple trays A, the drive mechanism 3 drives the first conveying screw 21, the second conveying screw 22, and the third conveying screw 23 to rotate synchronously in the same direction. At this time, the helical surface of the threaded groove b1 of the first conveying screw 21 pushes each first protrusion a1 of the bottom end A2 of each tray A to move along the first direction X. The helical surface of the threaded groove b2 of the second conveying screw 22 pushes the second protrusion a2 of the bottom end A2 of each tray A to move along the first direction X. The helical surface of the threaded groove b3 of the third conveying screw 23 pushes a protrusion a at the corner of the top end A1 of each tray A to move along the first direction X, thereby driving each tray A as a whole to move along the first direction X. During the movement of the tray A along the first direction X, the opposite two side edges of the tray A can respectively abut against the first limiting rod 4 and the second limiting rod 5, and slide relative to the first limiting rod 4 and the second limiting rod 5 along the first direction X.

[0022] The transfer device 100 provided in this application embodiment, through the cooperation of a first conveying screw 21, a second conveying screw 22, a third conveying screw 23, a first limiting rod 4, and a second limiting rod 5, can simultaneously and relatively securely hold and fix multiple trays A to the screw conveying mechanism 2. Furthermore, under the drive of the driving mechanism 3, the first conveying screw 21, the second conveying screw 22, and the third conveying screw 23 can rotate synchronously, thereby directly driving multiple trays A to move along the first direction X. The two side edges of the trays A respectively abut against the first limiting rod 4 and the second limiting rod 5 and slide along the second direction Y, which helps improve the stability of the trays A when moving along the first direction X. Compared to the related technologies that use a positioning support mechanism to store multiple trays A and a clamping and moving mechanism to transfer the trays A, the transfer device 100 of this application embodiment has a simpler structure and more streamlined working steps, thereby improving overall work efficiency. In some embodiments, the multiple threaded grooves b1 of the first conveying screw 21, the multiple threaded grooves b2 of the second conveying screw 22, and the multiple threaded grooves b3 of the third conveying screw 23 correspond one-to-one to form multiple sets of threaded groove groups B. The threaded grooves b1, b2, and b3 in the same set of threaded grooves B are aligned with each other along the second direction Y. The multiple sets of threaded groove groups B are arranged sequentially along the first direction X. One set of threaded groove groups B is used to jointly hold a material tray A.

[0023] In some embodiments, the first conveying screw 21, the second conveying screw 22 and the third conveying screw 23 are arranged sequentially along the second direction Y, and the third conveying screw 23 is used to abut against the fourth protrusion a4 at the corner of the junction of the top A1 and the second side A4 of the material tray A.

[0024] In other embodiments, the third conveying screw 23, the first conveying screw 21, and the second conveying screw 22 are arranged sequentially along the second direction Y. The third conveying screw 23 is used to abut against the third protrusion a3 at the corner of the junction of the top A1 and the first side A3 of the material tray A.

[0025] In some embodiments, the support 1 is provided with a pretreatment chamber 1a. The support 1 includes a first wall 11 and a second wall 12 arranged sequentially along a first direction X. The pretreatment chamber 1a is disposed between the first wall 11 and the second wall 12. A first conveying screw 21, a second conveying screw 22, a third conveying screw 23, a first limiting rod 4, and a second limiting rod 5 are disposed in the pretreatment chamber 1a. When applied to a test sorting machine 1000, the pretreatment chamber 1a serves as a chamber for temperature treatment of semiconductor devices held in trays A before testing. Multiple trays A are held in the pretreatment chamber 1a by a screw conveying mechanism 2.

[0026] In some embodiments, the two ends of the first limiting rod 4 are fixed to the first wall 11 and the second wall 12 respectively, and the two ends of the second limiting rod 5 are fixed to the first wall 11 and the second wall 12 respectively.

[0027] In some embodiments, the transfer device 100 includes a first mounting base 6 and a second mounting base 7, the first mounting base 6 and the second mounting base 7 are arranged sequentially on the bracket 1 along a first direction X, the two ends of the first conveying screw 21 are rotatably connected to the first mounting base 6 and the second mounting base 7 respectively, and the two ends of the second conveying screw 22 are rotatably connected to the first mounting base 6 and the second mounting base 7 respectively.

[0028] In some embodiments, the first mounting base 6 is fixed to the first wall 11, and the second mounting base 7 is fixed to the second wall 12.

[0029] In some embodiments, the second mounting base 7 is provided with a support surface 71, which is arranged in a direction opposite to the third direction Z. The support surface 71 is provided with a limiting member 72. The support surface 71 is used to support the tray A, which is disengaged from the first conveying screw 21 and the second conveying screw 22 along the first direction X. The limiting member 72 is used to abut against the bottom end A2 of the tray A in a direction opposite to the first direction X. After the tray A moves along the first direction X to disengage from the first conveying screw 21 and the second conveying screw 22, the bottom end A2 of the tray A will fall onto the support surface 71 of the second mounting base 7, and the limiting member 72 will abut against the bottom end A2 of the tray A in a direction opposite to the first direction X.

[0030] In some embodiments, the limiting member 72 is provided with an abutting plane 721 facing a direction opposite to the first direction X, the abutting plane 721 being used to abut against the bottom end A2 of the tray A in a direction opposite to the first direction X.

[0031] Please see Figure 3 and Figure 5In some embodiments, along the second direction Y, a first clearance space 2a is provided between the first conveying screw 21 and the second conveying screw 22. The first clearance space 2a is offset from the space of the screw conveying mechanism 2 for accommodating the tray A in the first direction. Along the third direction Z, a clamping assembly 73 is provided on the side of the second mounting base 7 facing away from the support surface 71. The clamping assembly 73 is provided with a flipping member 731, which can flip between a clamping position and a clearance position along an axis parallel to the second direction Y through the first clearance space 2a. When the flipper 731 flips to the clearance position, the flipper 731 is located in the first clearance space 2a; during the process of the flipper 731 flipping from the clearance position to the pressing position, the flipper 731 is used to push the bottom end A2 of the material tray A that has fallen into the support surface 71 towards the limiting member 72 along the first direction X; when the flipper 731 flips to the pressing position, along the first direction X, the flipper 731 and the limiting member 72 are arranged opposite to each other, and the flipper 731 and the limiting member 72 together clamp the bottom end A2 of the material tray A.

[0032] In some embodiments, the clamping assembly 73 includes a flipping shaft 732, a drive unit 733, a telescopic rod 734, a connecting rod 735, and a base 736. The drive unit 733 is connected to the telescopic rod 734 and is used to drive the telescopic rod 734 to reciprocate in a direction parallel to the first direction X. The telescopic rod 734 is connected to the connecting rod 735, and the connecting rod 735 is hinged to the flipping member 731. The flipping shaft 732 is disposed on the base 736 and is arranged parallel to the second direction Y. The base 736 is fixed to the second mounting seat 7. When the drive unit 733 drives the telescopic rod 734 to reciprocate in a direction parallel to the first direction X, the telescopic rod 734 drives the connecting rod 735 to move, and the connecting rod 735 in turn drives the flipping member 731 to flip around the flipping shaft 732 between a clamping position and a clearance position.

[0033] Please see Figure 1 and Figure 3 In some embodiments, the drive mechanism 3 includes a drive motor 31, a first synchronous pulley 32, a second synchronous pulley 33, a third synchronous pulley 34, and a synchronous belt 35. The first synchronous pulley 32, the second synchronous pulley 33, and the third synchronous pulley 34 are respectively connected to the first transmission screw 21, the second transmission screw 22, and the third transmission screw 23. The synchronous belt 35 is sleeved on the first synchronous pulley 32, the second synchronous pulley 33, and the third synchronous pulley 34. The drive motor 31 is used to drive the synchronous belt 35 to rotate, thereby driving the first synchronous pulley 32, the second synchronous pulley 33, and the third synchronous pulley 34 to rotate synchronously.

[0034] In some embodiments, the drive motor 31, the first synchronous pulley 32, the second synchronous pulley 33, the third synchronous pulley 34, and the synchronous belt 35 are disposed on the side of the first wall 11 facing away from the second wall 12. The drive mechanism 3 includes a first connecting shaft 36, a second connecting shaft 37, and a third connecting shaft 38. The first connecting shaft 36, the second connecting shaft 37, and the third connecting shaft 38 all pass through the first wall 11. The first connecting shaft 36 connects between the first synchronous pulley 32 and the first transmission screw 21, the second connecting shaft 37 connects between the second synchronous pulley 33 and the second transmission screw 22, and the third connecting shaft 38 connects between the third synchronous pulley 34 and the third transmission screw 23. By disposing the drive motor 31, the first synchronous pulley 32, the second synchronous pulley 33, the third synchronous pulley 34, and the synchronous belt 35 outside the pretreatment chamber 1a, it is beneficial to reduce the adverse effects of the high or low temperature environment inside the pretreatment chamber 1a on the drive motor 31 and the synchronous belt 35, and extend the service life of the drive motor 31 and the synchronous belt 35.

[0035] In some embodiments, the drive mechanism 3 includes a transmission wheel 311 and a transmission belt 312. The transmission wheel 311 is located on the output shaft of the drive motor 31. One end of the transmission belt 312 is sleeved on the transmission wheel, and the other end of the transmission belt 312 is sleeved on one end of the second synchronous pulley 33. The other end of the second synchronous pulley 33 is sleeved with a synchronous belt 35. During operation, the drive motor 31 starts, and its output shaft drives the transmission wheel 311 to rotate. The transmission wheel 311 transmits power to one end of the second synchronous pulley 33 through the transmission belt 312, thereby driving the second synchronous pulley 33 to rotate as a whole. Since the second synchronous pulley 33 is connected to the synchronous belt 35, and the synchronous belt 35 is simultaneously sleeved on the first synchronous pulley 32 and the third synchronous pulley 34, the rotation of the second synchronous pulley 33 will drive the synchronous belt 35 to rotate, and the rotation of the synchronous belt 35 will further drive the first synchronous pulley 32 and the third synchronous pulley 34 to rotate synchronously.

[0036] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, the support 1 is provided with an initial station 1b, which is used to accommodate the tray A waiting to be fed into the screw conveyor 2. The initial station 1b and the screw conveyor 2 are arranged in sequence along the first direction X. The transfer device 100 includes a pushing mechanism 8, which is fixed to the support 1. The pushing mechanism 8 is used to push the tray A located at the initial station 1b to move along the first direction X to the threaded groove b1 of the first conveyor screw 21, the threaded groove b2 of the second conveyor screw 2, and the threaded groove b3 of the third conveyor screw 23.

[0037] In some embodiments, when applied to the test sorting machine 1000, the initial station 1b is located in the pretreatment chamber 1a. The tray A containing semiconductor devices is vertically fed into the initial station 1b by the vertical lifting device 200, and then fed into the screw conveying mechanism 2 along the first direction X by the pushing mechanism 8, and held by a group of threaded grooves B arranged at the first position along the first direction X.

[0038] In some embodiments, the pushing mechanism 8 includes a first pushing component 81, a second pushing component 82, and a third pushing component 83. The first pushing component 81 and the second pushing component 82 are arranged opposite each other along the second direction Y, and the third pushing component 83 is arranged sequentially with the first pushing component 81 along the third direction Z. The first pushing component 81 and the second pushing component 82 are used to abut and push the bottom end A2 of the material tray A along the first direction X, and the third pushing component 83 is used to abut and push the material tray A close to the edge of the third conveying screw 23 along the first direction X.

[0039] In some embodiments, the first conveying screw 21, the second conveying screw 22, and the third conveying screw 23 are arranged sequentially along the second direction Y. The third conveying screw 23 is used to abut against the fourth protrusion a4 at the corner of the junction of the top end A1 and the second side A4 of the material tray A. The third pushing component 83 is used to abut against the junction of the top end A1 and the second side A4 of the material tray A along the first direction X, and / or, the third pushing component 83 is used to abut against the portion of the top end A1 near the second side A4, and / or, the third pushing component 83 is used to abut against the portion of the second side A4 near the top end A1.

[0040] In some embodiments, the initial station 1b is used to receive the tray A in the third direction Z. Along the second direction Y, one end of the first limiting rod 4 and one end of the second limiting rod 5 are respectively located on opposite sides of the initial station 1b. One end of the first limiting rod 4 and one end of the second limiting rod 5 are used to abut against the opposite side edges of the tray A located at the initial station 1b. One end of the first limiting rod 4 and one end of the second limiting rod 5 can limit the tray A located at the initial station 1b, which helps to reduce the offset or tilt of the tray A located at the initial station 1b in the second direction Y, thus preventing the tray A from accurately entering the screw conveyor mechanism 2.

[0041] In some embodiments, the first pushing component 81 includes a first push rod 811 and a first driving component 812 connected to each other. The first push rod 811 passes through the first wall 11, and the first driving component 812 is disposed on the side of the first wall 11 facing away from the second wall 12. The first driving component 812 is used to drive the first push rod 811 to reciprocate in a direction parallel to the first direction X. When the first pushing component 81 needs to push the tray A in the first direction X, under the drive of the first driving component 812, the end of the first push rod 811 away from the first driving component 812 extends out of the surface of the first wall 11 facing the second wall 12 in the first direction X. When resetting, the end of the first push rod 811 away from the first driving component 812 retracts into the first wall 11 in a direction opposite to the first direction X.

[0042] In some embodiments, the first drive component 812 is a cylinder, and the piston part of the cylinder is connected to the first push rod 811. When the cylinder is working, the piston part performs reciprocating extension and retraction motion, thereby driving the first push rod 811 to move reciprocally in a direction parallel to the first direction X, so as to achieve contact and push of the bottom end A2 of the material tray A.

The specific structure of the second push rod 821 and the second driving component 822 can be referred to the first pushing component 81, and will not be described in detail here.

[0046] In some embodiments, the third pushing component 83 includes a third push rod 831 and a third driving component 832 connected together. The third driving component 832 is used to drive the third push rod 831 to reciprocate along a direction parallel to the first direction X.

The first support plate 131 is arranged perpendicular to the third direction Z, and the second support plate 132 is arranged perpendicular to the first direction X. The first support plate 131 is used to abut against the bottom end A2 of the material tray A in a direction opposite to the third direction Z, and the second support plate 132 is used to abut against the bottom end A2 of the material tray A in the first direction X.

[0048] In some embodiments, the support 1 is provided with a second limiting component 14 for limiting the material tray A located at the initial station 1b. The second limiting component 14 is disposed opposite to the first limiting component 13 along the first direction X. The second limiting component 14 includes a third support plate 141 and a fourth support plate 142. The fourth support plate 142 is disposed on one side of the third support plate 141. The third support plate 141 is disposed perpendicular to the third direction Z. The fourth support plate 142 is disposed perpendicular to the first direction X. The third support plate 141 is used to abut against the bottom end A2 of the material tray A in a direction opposite to the third direction Z.

[0049] In some embodiments, the support 1 is provided with a third limiting component 15 for limiting the material tray A located at the initial station 1b. The third limiting component 15 includes a fifth support plate 151 and a sixth support plate 152. The sixth support plate 152 is disposed on one side of the fifth support plate 151. The fifth support plate 151 is disposed perpendicular to the first direction X, and the sixth support plate 152 is disposed perpendicular to the second direction Y.

[0050] In some embodiments, a second clearance space 1c is provided between the first limiting component 13 and the second limiting component 14 along the second direction Y. The second clearance space 1c is used for the lifting member of the vertical conveying device of the test sorting machine 1000 to pass through along the third direction Z. During operation, the lifting member lifts the tray A along the third direction Z and sends the tray A into the initial station 1b. As the lifting member passes through the second clearance space 1c along the third direction Z and crosses the first limiting component 13 and the second limiting component 14, the bottom end A2 of the tray A first abuts against the first support plate 131 and the third support plate 141 respectively. As the lifting member continues to move, the bottom end A2 of the tray A eventually disengages from the lifting member, and the first support plate 131 and the third support plate 141 replace the lifting member in lifting the tray A.

[0051] Please see Figure 1 and Figure 2 Based on the same inventive concept, this application provides a test sorting machine 1000, including the transfer device 100 in any of the above embodiments.
