Description

Technical Field

[0001] This invention relates to the field of die bonding equipment technology, specifically to a die supply platform. Background Technology

[0002] In the LED packaging process, the wafer needs to be transferred to a designated area by a die bonder. During the operation of the die bonder, the die ring is usually supported by a die supply platform, and then the ejector pin lifts the wafer to be transferred on the blue film of the die ring. The die bonder nozzle picks up the chip on the die ring and firmly connects the chip to the packaging substrate to achieve die bonding.

[0003] Existing crystal supply platforms typically have a clamping mechanism on one side of the platform. After the crystal ring is placed in the designated area, the clamping mechanism squeezes the outer surface of the crystal ring to fix it.

[0004] Crystal rings come in different sizes to meet different production needs. The above-mentioned fixing method can only fix crystal rings of a single size or crystal rings of similar size. When crystal rings with large size differences are required, it is often necessary to replace them with crystal supply platforms of different sizes, and reinstallation and debugging are required. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a crystal supply platform that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a crystal supply platform, comprising a moving platform and a substrate, the substrate being mounted on the moving platform, characterized in that it further comprises: a support ring, the support ring being rotatably mounted on the upper side of the substrate; a lower swing arm, the lower swing arm serving as a supporting component for the crystal ring, and having at least three arms, one end of the lower swing arm being hinged to the upper surface of the support ring, and the other end of the lower swing arm being fitted with an inner contact head, the projection of the inner contact head in the vertical direction being located within the inner circle of the crystal ring, the space between the inner contact heads reserving lifting space for the ejector pins; and an upper swing arm. The upper and lower swing arms correspond one-to-one. One end of the upper swing arm is hinged to the upper surface of the support ring, and the other end of the upper swing arm is equipped with an outer contact head. The projection of the outer contact head in the vertical direction is located outside the crystal ring. A pushing mechanism is installed on the support ring and is used to drive the lower and upper swing arms to swing. The pushing mechanism can control the swing angle of the lower and upper swing arms respectively, so that the inner contact head is pressed against the inner arc surface of the crystal ring and the outer contact head is pressed against the outer arc surface of the crystal ring, or so that the inner contact head is away from the inner arc surface of the crystal ring and the outer contact head is away from the outer arc surface of the crystal ring.

[0007] Furthermore, the upper surface of the support ring has a non-installation area, and the movement trajectories of the upper and lower swing arms do not overlap with the non-installation area.

[0008] Furthermore, the upper swing arm is located above the lower swing arm in the vertical direction, and the upper and lower swing arms have a height difference in the vertical direction; the projections of the upper and lower swing arms in the vertical direction intersect at a point.

[0009] Furthermore, a hollow rod is fixed on the ring, and the height of the hollow rod is between the upper swing arm and the lower swing arm; the pushing mechanism includes a clutch assembly and a slide assembly, both of which are slidably mounted on the hollow rod. The clutch assembly moves along the length of the hollow rod, and there are two sets of slide assemblies, which are respectively connected to the upper swing arm and the lower swing arm.

[0010] Furthermore, an upper slider is slidably mounted on the upper swing arm, and a lower slider is slidably mounted on the lower swing arm. One side of one set of slide table assemblies is rotatably connected to the upper slider, and one side of the other set of slide table assemblies is rotatably connected to the lower slider. The clutch assembly has an engaged state and a disengaged state with the two sets of slide table assemblies. In the engaged state, the slide table assembly is disengaged from the hollow rod, and the clutch assembly drives the slide table assembly to move synchronously. In the disengaged state, the slide table assembly is locked onto the hollow rod.

[0011] Furthermore, the slide assembly includes: a connecting seat, the connecting seat having a cavity inside, and the cavity having an opening on the side near the hollow rod, and a first clearance opening on one side of the connecting seat; a pushing block, the pushing block being slidably disposed within the cavity of the connecting seat, the moving direction of the pushing block being perpendicular to the moving direction of the connecting seat in the horizontal plane, the pushing block having a sloping protrusion on the side near the opening so that the clutch assembly can push the pushing block to move when moving, and the pushing block also having a wedge-shaped portion on the side away from the sloping protrusion; a first spring being disposed within the cavity, the two ends of the first spring being respectively connected to the cavity and the pushing block, and the first spring generating a force on the pushing block pushing towards the clutch assembly.

[0012] Furthermore, the slide assembly further includes: a lifting block, which is slidably disposed in the cavity along the vertical direction and located above the pushing block, the bottom end of the lifting block being in contact with the wedge-shaped portion so that the pushing block can push the lifting block to move vertically; a pressing block, which is slidably disposed in the cavity and parallel to the lifting block, the bottom end of the pressing block extending through to the outside of the cavity; and a connecting member, which is rotatably disposed in the cavity, and the two ends of the connecting member are respectively connected to the pressing block and the lifting block, so that when the lifting block rises, the bottom end of the pressing block falls to make close contact with the surface of the hollow rod.

[0013] Furthermore, a movable plate is provided inside the cavity, and the moving direction of the movable plate is parallel to the moving direction of the connecting seat. A second spring is connected between the movable plate and the connecting seat. A limiting pin is fixedly provided on the side of the movable plate near the pushing block, and a locking protrusion is fixedly provided on the side of the pushing block near the movable plate. The locking protrusion can be engaged with the end face of the limiting pin so that the limiting pin can limit the pushing block.

[0014] Furthermore, the clutch assembly includes a clutch block and a nut, with the clutch block fixedly mounted on the nut; a screw is rotatably mounted in the hollow portion of the hollow rod, and the nut is sleeved on the outer circumference of the screw and engages with it; a bevel gear set is provided at one end of the hollow rod, with the axis of one bevel gear fixedly connected to the axis of the screw, and the other bevel gear rotatably mounted on the upper surface of the support ring, the shaft of the other bevel gear extending through to the lower surface of the support ring, and a first driven wheel fixedly mounted at its axis; a first drive assembly is provided on the lower surface of the support ring, the first drive assembly being used to drive the first driven wheel to rotate.

[0015] Furthermore, the first drive assembly includes: a first motor mounted on a support ring; a first drive wheel fixedly connected to the shaft at the output end of the first motor; and a first timing belt sleeved on the outer circumferential surfaces of the first driven wheel and the first drive wheel.

[0016] The present invention has the following beneficial effects:

[0017] (1) The crystal supply platform fixes the crystal ring by setting a lower swing arm and an inner contact head. At the same time, it sets an upper swing arm and an outer contact head so that the outer contact head can press the outer arc surface of the crystal ring. The rotation angle of the lower swing arm and the upper swing arm are controlled by the pushing mechanism, so that the device can fix crystal rings of different sizes with a large size range.

[0018] (2) The crystal supply platform drives the lower and upper swing arms by swinging, so that the inner contact head can press the inner arc surface of the crystal ring. Compared with controlling the outer and inner contact heads by linear motion, the swinging method makes the diameter of the support ring occupied by the lower and upper swing arms smaller, thereby reducing the size of the support ring and saving installation space. At the same time, the lower swing arm can release the corresponding empty area inside the crystal ring during the process of fixing the crystal ring, which will not hinder the upward movement of the ejector pin device, and can also play a supporting role for the crystal ring.

[0019] (3) The crystal supply platform is equipped with a clutch assembly and a slide assembly. When the clutch assembly and the slide assembly are engaged, they can drive the lower swing arm and the upper swing arm to move. When they are disengaged, the slide assembly is locked on the hollow rod, so that the lower swing arm and the upper swing arm can self-lock when fixing the crystal ring, thus preventing the fixing from loosening.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0048] The following is based on Figure 1 - Figure 24 Describe the die supply platform provided in the embodiments of the present invention.

[0049] Please see Figure 1 - Figure 10 The die supply platform provided in this embodiment of the invention includes a moving platform 1 and a substrate 2. The substrate 2 is mounted on the moving platform 1. The moving platform 1 is used to drive the substrate 2 to move in a horizontal plane. On the upper side of the substrate 2, that is, on the side of the substrate 2 away from the moving platform 1, a support ring 5 is rotatably mounted. Specifically, a rotary bearing can be installed on the substrate 2 and the support ring 5 can be fixed to the rotary bearing. It should be noted that the areas inside the support ring 5 on the moving platform 1 and the substrate 2 are empty areas, so that the ejector pin device can eject from the lower part of the empty area.

[0050] Furthermore, a lower swing arm 10 is hinged to the upper surface of the support ring 5. The lower swing arm 10 serves as a supporting component for the crystal ring 3. The upper surface of the lower swing arm 10 is used to support the crystal ring 3. At least three lower swing arms 10 are provided, preferably multiple lower swing arms 10 are distributed in a circumferential array on the support ring 5. An inner contact head 12 is installed at the other end of the lower swing arm 10. The projection of the inner contact head 12 in the vertical direction is located on the inner circle of the crystal ring 3. The space between multiple inner contact heads 12 provides lifting space for the ejector pin.

[0051] It should be noted that the top of the inner contact 12 needs to be lower than the upper surface of the crystal ring 3 to avoid the inner contact 12 from contacting the blue film on the crystal ring 3. For ease of installation, the inner contact 12 can be mounted on the second mounting block 11 and the second mounting block 11 can be fixed to the end of the lower swing arm 10. The upper surface of the second mounting block 11 needs to be flush with the upper surface of the lower swing arm 10.

[0052] Furthermore, an upper swing arm 6 is hinged to the upper surface of the support ring 5. The upper swing arm 6 corresponds one-to-one with the lower swing arm 10. An external contact head 9 is installed at the other end of the upper swing arm 6. The projection of the external contact head 9 in the vertical direction is located outside the crystal ring 3. Accordingly, the external contact head 9 can be installed on the first mounting block 8, and the first mounting block 8 is fixed to the end of the upper swing arm 6.

[0053] In addition, a pushing mechanism is installed on the support ring 5. The pushing mechanism is used to drive the lower swing arm 10 and the upper swing arm 6 to swing. The pushing mechanism can control the swing angle of the lower swing arm 10 and the upper swing arm 6 respectively, so that the inner contact head 12 is pressed against the inner arc surface of the crystal ring 3 and the outer contact head 9 is pressed against the outer arc surface of the crystal ring 3, or the inner contact head 12 is moved away from the inner arc surface of the crystal ring 3 and the outer contact head 9 is moved away from the outer arc surface of the crystal ring 3.

[0054] Specifically, when the pushing mechanism drives the lower swing arm 10 to swing, the lower swing arm 10 drives the inner contact head 12 to approach and press against the inner arc surface of the crystal ring 3, thereby fixing the crystal ring 3 from the inside of the crystal ring 3. At the same time, the lower swing arm 10 carries the crystal ring 3. During this process, the lower swing arm 10 can also release the corresponding empty area inside the crystal ring 3 so that the ejector pin device can move upward. In order to avoid insufficient fixing force due to the low height of the inner contact head 12, the pushing mechanism simultaneously drives the upper swing arm 6 to swing, so that the multiple outer contact heads 9 approach and press against the outer arc surface of the crystal ring 3, thereby fixing the crystal ring 3 from the outside of the crystal ring 3. By controlling the swing angle of the lower swing arm 10 and the upper swing arm 6 respectively, crystal rings 3 of different sizes can be fixed.

[0055] In this embodiment, the reason for fixing the crystal ring 3 by controlling the lower swing arm 10 and the upper swing arm 6 to move in a swinging manner rather than in a linear manner is that, compared to controlling the outer contact head 9 and the inner contact head 12 in a linear manner, the swinging manner makes the diameter of the support ring 5 occupied by the lower swing arm 10 and the upper swing arm 6 smaller, thereby reducing the size of the support ring 5 and saving installation space.

[0056] See Figure 4 and 5 To facilitate the movement of the crystal ring supply device and the crystal picking device, a non-installation area is provided on the upper surface of the support ring 5. The movement trajectories of the upper swing arm 6 and the lower swing arm 10 do not overlap with the non-installation area. This ensures that when fixing crystal rings 3 of different sizes, a non-installation area exists on the support ring 5. The crystal ring supply device can place the crystal ring 3 within the space enclosed by the upper swing arm 6 and the lower swing arm 10 through the non-installation area, and the crystal picking device can complete the crystal picking action through the non-installation area without having to cross the upper swing arm 6 and the lower swing arm 10, thereby avoiding additional travel during the movement of the crystal picking device.

[0057] See Figure 4 as well as Figure 7 - Figure 9 To facilitate the installation of the pushing mechanism, the upper swing arm 6 is positioned above the lower swing arm 10 in the vertical direction, and the upper swing arm 6 and the lower swing arm 10 have a height difference in the vertical direction. The pushing mechanism can then be installed in the gap between the two. To compensate for the height difference between the outer contact head 12 and the crystal ring 3, an extension block 7 can be fixed at the end of the upper swing arm 6, and the first mounting block 8 is fixed at the lower end of the extension block 7.

[0058] Furthermore, the projections of the upper swing arm 6 and the lower swing arm 10 in the vertical direction have an intersection point. In the initial state, that is, before the fixed crystal ring 3, part of the pushing device coincides with the intersection point of the two projections, so that the pushing device can simultaneously push the upper swing arm 6 and the lower swing arm 10 to move in the initial state.

[0059] See Figure 7 - Figure 10 A hollow rod 15 is fixed on the support ring 5. The hollow part of the hollow rod 15 passes through the upper and lower sides of the hollow rod 15. The height of the hollow rod 15 is between the upper swing arm 6 and the lower swing arm 10.

[0060] Furthermore, the driving mechanism includes a clutch assembly and a slide assembly. Both the clutch assembly and the slide assembly are slidably mounted on the hollow rod 15. The clutch assembly moves along the length of the hollow rod 15. There are two sets of slide assemblies, and the two sets of slide assemblies are respectively connected to the upper swing arm 6 and the lower swing arm 10, so that when the clutch assembly moves, it can push the upper swing arm 6 and the lower swing arm 10 to swing through the two sets of slide assemblies respectively.

[0061] See Figure 7 - Figure 12 In order for the pushing mechanism to control the swing angle of the upper swing arm 6 and the lower swing arm 10 respectively, an upper slider 13 is slidably provided on the upper swing arm 6, and a first guide rail 61 is fixed on the upper swing arm 6. The upper slider 13 cooperates with the first guide rail 61. A lower slider 14 is slidably provided on the lower swing arm 10, and a second guide rail 101 is fixed on the lower swing arm 10. The lower slider 14 cooperates with the second guide rail 101. One side of one set of slide assembly is rotatably connected to the upper slider 13 through a slewing bearing 24, and one side of another set of slide assembly is rotatably connected to the lower slider 14 through another slewing bearing 24, so that the slide assembly and the upper swing arm 6 or the lower swing arm 10 can rotate relative to each other when moving.

[0062] Furthermore, combined Figure 4 and Figure 6The clutch assembly and the two sets of slide assemblies have an engaged state and a disengaged state. In the engaged state, the slide assembly is disengaged from the hollow rod 15, the clutch assembly and the slide assembly form a whole, and drive the slide assembly to move synchronously. In the disengaged state, the clutch assembly is separated from the slide assembly, and the slide assembly is locked on the hollow rod 15.

[0063] See Figure 8 as well as Figure 11 - Figure 13 The clutch assembly consists of a clutch block 18 and a nut 17. There are two clutch blocks 18, and the upper and lower sides of the nut 17 are fixed to the two clutch blocks 18 respectively to correspond to the two slide assemblies. A third guide rail 151 is fixed to the inner wall of the hollow rod 15. A sliding groove 19 is provided on the side of the nut 17. The clutch assembly can slide inside the hollow rod 15. A screw 16 is rotatably provided in the hollow part inside the hollow rod 15. The nut 17 is sleeved on the outer circumferential surface of the screw 16 and cooperates with the screw 16. The clutch assembly can be moved by rotating the screw 16.

[0064] See Figure 13 - Figure 19 The aforementioned slide assembly includes a connecting seat 20, which has a cavity inside and an opening on the side of the cavity near the hollow rod 15. A first clearance opening 25 is also provided on one side of the connecting seat 20. The clutch block 18 can disengage from the slide assembly through the first clearance opening 25. The connecting seat 20 can be formed by two first enclosure plates 21, two second enclosure plates 22, and a cover plate 23. In this case, the first clearance opening 25 can be opened on the second enclosure plate 22, and the slewing bearing 24 is installed on the cover plate 23. A roller 211 is rotatably provided on the first enclosure plate 21, and a raceway 152 is provided on the outer side of the hollow rod 15. The roller 211 can move within the raceway 152, thereby allowing the slide assembly to slide along the hollow rod 15.

[0065] Furthermore, combined Figure 16 and Figure 18 A push block 30 is also slidably provided in the cavity of the connecting seat 20. The moving direction of the push block 30 is perpendicular to the moving direction of the connecting seat 20 in the horizontal plane. The push block 30 has a sloping protrusion 301 on the side near the opening. The sloping protrusion 301 extends outward of the push block 30 so that the clutch assembly, i.e. the clutch block 18, can push the push block 30 to move when it moves. The push block 30 also has a wedge-shaped part 302 on the side away from the sloping protrusion 301. The height change of the wedge-shaped part 302 is parallel to the vertical direction. Preferably, the push block 30 is symmetrically arranged about the clutch assembly. Preferably, one side of the clutch block 18 is chamfered.

[0066] Furthermore, combined Figure 16A first spring 32 is provided in the cavity. The two ends of the first spring 32 are respectively connected to the cavity and the push block 30. The first spring 32 generates a force on the push block 30 to push towards the clutch assembly.

[0067] See Figure 16 as well as Figure 18 - Figure 21 For ease of installation, two fixed frames 26 can be symmetrically fixed in the cavity, leaving a certain distance between the two fixed frames 26 as an opening. A transverse through-hole 261 is provided on the side of the fixed frame 26 near the opening. The push block 30 is slidably installed on the fixed frame 26 and can pass through the transverse through-hole 261 to contact the clutch block 18. A telescopic rod 31 is provided between the push block 30 and the fixed frame 26. When the telescopic rod 31 is at its maximum length, the clutch block 18 contacts the non-sloping protrusion 301 of the push block 30. At this time, the first spring 32 is sleeved on the outer circumferential surface of the telescopic rod 31.

[0068] Specifically, when the clutch assembly and the slide assembly are engaged, the non-sloping protrusion 301 of the push block 30 contacts the clutch block 18, and under the action of the first spring 32, the sloping protrusion 301 prevents the clutch block 18 from disengaging from the slide assembly. When the inner contact head 12 or the outer contact head 9 contacts the crystal ring 3, the rotation of the upper swing arm 6 or the lower swing arm 10 is hindered. Since the upper swing arm 6 and the lower swing arm 10 are respectively connected to the slide assembly, the slide assembly stops moving. At this time, the clutch block 18 continues to move and contacts the sloping protrusion 301 of the push block 30. Due to the gradient change of the sloping protrusion 301, the forward movement of the clutch block 18 drives the push block 30 to move to the sides to the maximum distance, so that the clutch block 18 can disengage from the slide assembly, so that the slide assembly and the clutch assembly are in a disengaged state.

[0069] It should be noted that, in combination Figure 6 Since the upper swing arm 6 and the lower swing arm 10 are connected to different slide assemblies and the two slide assemblies do not interfere with each other, when one slide assembly stops moving, the other slide assembly can still continue to move under the drive of the clutch assembly, thereby automatically pressing the crystal ring 3 against the inner and outer arc surfaces of the crystal ring 3.

[0070] See Figure 16 - Figure 18To ensure the slide assembly can lock onto the hollow rod 15 when it is disengaged from the clutch assembly, the slide assembly further includes a lifting block 28. The lifting block 28 is vertically slidable within the cavity and positioned above the push block 30. The bottom end of the lifting block 28 abuts against the wedge-shaped portion 302, allowing the push block 30 to push the lifting block 28 to move vertically. The lifting block 28 is vertically spaced from the inner wall of the cavity to facilitate upward movement. A pressing block 27 is also slidably disposed within the cavity, parallel to the lifting block 28. The bottom end of the pressing block 27... The connection extends to the outside of the cavity and leaves a certain distance, preferably 3 to 7 mm, from the end face of the hollow rod 15. A connecting member 29 is also rotatably provided inside the cavity, and the two ends of the connecting member 29 are respectively connected to the lower pressing block 27 and the lifting block 28. Specifically, a first receiving groove 271 is provided on the side of the lower pressing block 27 near the connecting member 29, and a second receiving groove 281 is provided on the side of the lifting block 28 near the connecting member 29. The two ends of the connecting member 29 are respectively located in the first receiving groove 271 and the second receiving groove 281, so that when the lifting block 28 rises, the bottom end of the lower pressing block 27 falls to make close contact with the surface of the hollow rod 15.

[0071] With the fixed frame 26 installed, the lifting block 28 is slidably installed inside the fixed frame 26, and the connecting piece 29 is rotatably installed on the fixed frame 26. A vertical through-hole 262 is also provided on the fixed frame 26, and the pressing block 27 can pass through the vertical through-hole 262 to contact the end face of the hollow rod 15.

[0072] Preferably, the part of the lower pressure block 27 that contacts the hollow rod 15 has friction texture, or a material that can increase friction, such as rubber or polyurethane, is used to increase the friction when the lower pressure block 27 contacts the hollow rod 15.

[0073] See Figure 16 and Figure 17 In order to ensure that the lower pressure block 27 is always in close contact with the end face of the hollow rod 15 when the clutch assembly and the slide assembly are disengaged, a movable plate 33 is provided in the cavity. The moving direction of the movable plate 33 is parallel to the moving direction of the connecting seat 20, and a second spring 34 is connected between the movable plate 33 and the connecting seat 20. A limiting pin 35 is fixed on the side of the movable plate 33 near the push block 30, and a locking protrusion 303 is fixed on the side of the push block 30 near the movable plate 33. The locking protrusion 303 can be locked onto the end face of the limiting pin 35 so that the limiting pin 35 can limit the push block 30.

[0074] Specifically, when the clutch block 18 pushes the push block 30 to move, the locking protrusion 303 pushes the limiting pin 35 and causes the movable plate 33 to compress the second spring 34, thereby causing the locking protrusion 303 to pass the limiting pin 35. Then, the movable plate 33 returns to its original position under the elastic force of the second spring 34, and drives the limiting pin 35 to lock the locking protrusion 303, thereby keeping the position of the push block 30 unchanged. As a result, when the stage assembly and the clutch assembly are in a disengaged state, the slide assembly can be locked on the hollow rod 15.

[0075] When a fixed frame 26 is provided, there is a gap space 48 between the fixed frame 26 and the inner wall of the cavity, and the movable plate 33 is located in the gap space 48. A through groove 263 is also provided on the fixed frame 26, and the limiting pin 35 can move through the through groove 263.

[0076] When it is necessary to release the fixing of the crystal ring 3, the clutch block 18 is moved in the opposite direction, which will drive the clutch block 18 back into the slide assembly and contact the movable plate 33. At this time, the slide assembly is locked on the hollow rod 15. The clutch block 18 can push the movable plate 33 to release the limit pin 35 from the limit of the locking protrusion 303. The push block 30 can be reset under the elastic force of the first spring 32, which will cause the lower pressure block 27 to disengage from the hollow rod 15. The clutch assembly and the slide assembly return from the disengaged state to the engaged state. The upper swing arm 6 and the lower swing arm 10 can move together with the slide assembly to the initial position.

[0077] See Figure 3 , Figure 4 and Figure 7 To facilitate the rotation of the screw 16, a bevel gear set 40 is provided at one end of the hollow rod 15. The shaft of one bevel gear is fixedly connected to the shaft of the screw 16, and the other bevel gear is rotatably mounted on the upper surface of the support ring 5. The shaft of the other bevel gear passes through the lower surface of the support ring 5 and a first driven wheel 371 is fixedly provided at the shaft. Each upper swing arm 6 and lower swing arm 10 is equipped with a screw 16. A set of bevel gears 40 is provided at the shaft of each screw 16. A first drive assembly is provided on the lower surface of the support ring 5. The first drive assembly is used to drive the first driven wheel 371 to rotate and drive the screw 16 to rotate through the bevel gear set 40, thereby controlling the position of the clutch assembly.

[0078] See Figure 3 , Figure 4 , Figure 7 and Figure 22The aforementioned first drive assembly includes a first motor 36, which is mounted on the ring 5. Preferably, the first motor 36 is mounted on the upper surface of the ring 5. A first drive wheel 37 is fixed at the shaft center of the output end of the first motor 36. The first drive wheel 37 is located on one side of the lower surface of the ring 5. A first synchronous belt 39 is sleeved on the outer circumferential surface of the first driven wheel 371 and the first drive wheel 37. A first guide wheel 38 can also be provided on the lower surface of the ring 5 to adjust the position and tension of the first synchronous belt 39.

[0079] See Figure 2 A cover 4 is provided on the support ring 5 to shield and protect the upper swing arm 6 and the lower swing arm 10. A second clearance opening 46 and a third clearance opening 47 are provided on the cover 4 corresponding to the non-installation area to facilitate the movement of the crystal ring supply device and the crystal picking device.

[0080] See 1. Figure 23 and Figure 24 To facilitate the rotation of the support ring 5, thereby driving the crystal ring 3 to rotate and adjust the angle of the wafer, a toothed ring 45 is fixed at the bottom end of the support ring 5. A second drive assembly is provided on the substrate 2. The second drive assembly includes a second motor 41 mounted on the substrate 2. A second drive wheel 42 is fixed at the shaft of the output end of the second motor 41. The second drive wheel 42 drives the toothed ring 45 to rotate through the second synchronous belt 44, thereby adjusting the angle of the support ring 5. A second guide wheel 43 can also be provided on the substrate 2 to adjust the position and tension of the second synchronous belt 44.

[0081] In use (operation), in the initial state, the upper swing arm 6 is located on the side furthest from the center of the support ring 5, and the lower swing arm 10 is located on the side closest to the center of the support ring 5. At this time, the clutch assembly and the slide assembly are engaged. After the crystal ring supply device places the crystal ring 3 onto the lower swing arm 10, the first drive assembly is activated, driving the screw 16 to rotate, thereby driving the clutch assembly to move. The clutch assembly drives the slide assembly to move, thereby driving the upper swing arm 6 and the lower swing arm 10 to rotate. When the inner contact head 12 or the outer contact head 9 contacts the crystal ring 3, the lower swing arm 10 or the upper swing arm 6 is obstructed and stops moving, thereby causing one slide assembly to stop moving. At this time, the clutch block 18 drives the push block 30 to move laterally, causing the lower pressure block 27 to press against the end face of the hollow rod 15, so that the slide assembly is locked on the hollow rod 15. At this time, the clutch assembly is disengaged from the slide assembly. The clutch assembly continues to move until it is disengaged from the other slide assembly.

[0082] When it is necessary to release the fixing of the crystal ring 3, the first drive component rotates in the reverse direction, causing the clutch component to move in the reverse direction, driving the clutch block 18 to re-enter the slide assembly, and pushing the movable plate 33 to release the limit pin 35 from the limit of the locking protrusion 303, so that the lower pressure block 27 disengages from the hollow rod 15, and the clutch component and the slide assembly return from the disengaged state to the engaged state. The upper swing arm 6 and the lower swing arm 10 can then move together with the slide assembly to the initial position.
