Description

Technical Field

[0001] This invention relates to the field of process lamp chip packaging technology, specifically to a process lamp chip packaging device and process. Background Technology

[0002] When packaging existing process LED chips, the FPC circuit board is first placed flat on a fixture. Then, a magnetic steel sheet is attached to the fixture to press the FPC circuit board firmly, exposing the gold-plated probe on the PFC circuit board. The fixture is then placed on the fixed platform of a die bonder. The die bonder then attaches the gold-plated chip to the FPC circuit board. After die bonding, the FPC circuit board, supported by the fixture, is reflow soldered. After cooling, the magnetic steel sheet is removed, and the FPC circuit board is removed from the fixture for subsequent packaging and cutting.

[0003] However, when pressing and fixing the magnetic steel sheet to the PFC circuit board or removing it, it is necessary to align the multiple openings of the magnetic steel sheet with the gold-plated probe position of the PFC circuit board. At the same time, since the magnetic steel sheet itself is relatively thin, manual placement of the magnetic steel sheet relies on visual judgment, and it is difficult to guarantee the alignment accuracy between the openings of the steel sheet and the gold-plated probe of the FPC. This can easily lead to subsequent chip misalignment and friction between the magnetic steel sheet and the gold plating layer, causing wear on the probe. In addition, repeated manual handling of the magnetic steel sheet can easily cause deformation of the steel sheet (such as warping and opening deformation). To address this, we propose a process lamp bead packaging device and process. Summary of the Invention

[0004] The purpose of this invention is to provide a process and device for packaging process lamp beads to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a process lamp bead packaging device, comprising a fixture body for supporting an FPC circuit board, a die bonder body for fixing chips onto the FPC circuit board, a wire bonding machine for soldering the die bonded FPC circuit board, and a packaging machine for packaging the FPC circuit board. The die bonder body has a worktable at its entrance, which supports the fixture body. The worktable has two openings, and both ends of the openings are provided with a connection alignment mechanism. The connection alignment mechanism is used to sequentially align and connect the PFC circuit board and the magnetic steel sheet on the fixture body. The fixture body has a connection port corresponding to the connection alignment mechanism.

[0006] The workbench is equipped with a support mechanism inside, which is used to connect the alignment mechanism. The workbench is also equipped with a fixing mechanism inside, which is used to position the support mechanism. The fixing mechanism and the support mechanism cooperate with each other.

[0007] Furthermore, the connection alignment mechanism includes a transverse bearing shell, a synchronous adjustment component, a first vertical connecting shell, a second vertical connecting shell, a support shell, and a limiting stop. The transverse bearing shell is connected to the fixing mechanism, and the synchronous adjustment component is disposed on the transverse bearing shell and is used to connect the first vertical connecting shell and the second vertical connecting shell.

[0008] The support shell is provided in four parts, and a support block is fixedly connected to one side of each of the four support shells. The four support blocks are distributed in pairs at the first vertical connecting shell and the second vertical connecting shell. An adjustment component is provided at the first vertical connecting shell, and the adjustment component is used to adjust the two support blocks thereon. A synchronization component is provided at the two support shells between the adjacent first vertical connecting shell and the second vertical connecting shell.

[0009] The limiting stop is mounted on the support shell, and the support mechanism is connected to multiple limiting stops.

[0010] Furthermore, the limiting stop includes a limiting plate, a connecting member, a spreading member, a limiting block, and a guide member. The top of the support shell is provided with a moving opening. The limiting plate slides through the moving opening and the connecting opening. The connecting member is located at the bottom of the limiting plate, and the connecting plate is connected to the support mechanism.

[0011] The top of the limiting plate is provided with a slot, and the supporting member is located at the slot. A positioning plate is fixedly installed on the outside of the supporting shell, and the positioning plate is connected to the supporting member. The limiting block is located on the upper surface of the fixture body. The guide member is set between the limiting block and the limiting plate. Through the provided limiting stop, the FPC circuit board is positioned, and the magnetic steel sheet is vertically pressed down and fixed to the FPC circuit board.

[0012] Furthermore, the connector includes a connecting rod and a connecting plate. The connecting rod is fixedly installed at the bottom of the limiting plate, and the bottom of the connecting rod extends to the support mechanism. There are two connecting plates, both of which are fixedly installed at the bottom of the connecting rod. Through the connector, the limiting plate is connected to the support mechanism.

[0013] Furthermore, the support shell is provided with an L-shaped groove at the position corresponding to the guide member, and the limiting plate is provided with an inclined groove at the position corresponding to the guide member. The guide member includes a first guide rod and a second guide rod. The first guide rod slides through the L-shaped groove and the inclined groove respectively. One end of the second guide rod is fixedly connected to the first guide rod, and the other end of the second guide rod is fixedly connected to the limiting block.

[0014] Furthermore, the supporting component includes a supporting block, a connecting rod, a sliding rod, a buffer spring, an inclined block, and a pressing component. The supporting block slides through the top of the slot. One end of the connecting rod is rotatably connected to the bottom of the supporting block via a pin, and the other end of the connecting rod is rotatably connected to a connecting seat via a pin. The connecting seat is fixedly installed on the top of the sliding rod. The buffer spring is sleeved on the outside of the sliding rod, and both ends of the buffer spring are fixedly connected to the inner wall of the slot and the inclined block, respectively. The inclined block is fixedly installed at the bottom of the sliding rod. The pressing component is located at the bottom of the slot. The support shell has a support opening corresponding to the position of the pressing component. Through the supporting component, the magnetic steel sheet is supported and opened at the same time, preventing the magnetic steel sheet from bending.

[0015] Furthermore, the extrusion component includes a connecting spring, an extrusion block, an extrusion rod, and a contact block. One end of the connecting spring is fixedly installed on the inner wall of the slot, and the other end of the connecting spring is fixedly connected to the extrusion block. There are two extrusion rods, both of which slide through the support opening and the slot. One end of each extrusion rod is fixedly connected to the extrusion block, and the other end of each extrusion rod is fixedly connected to the contact block. The contact block is slidably connected to the positioning plate. Through the provided extrusion component, the position of the expansion block can be adjusted.

[0016] Furthermore, the fixing mechanism includes a fixed base, a fixed rod, and a pushing component. The pushing component is installed at the bottom of the workbench, and one end of the pushing component is fixedly connected to the fixed base. The fixed rod is fixedly installed on the fixed base, and the transverse bearing shell is fixedly installed on the top of the fixed rod. The support mechanism is sleeved on the outside of the fixed rod. Through the fixed mechanism, it can cooperate with the support mechanism.

[0017] Furthermore, the support mechanism includes a support frame, a mating component, and a synchronization frame. The support frame is slidably sleeved on the outside of the fixed rod, and the mating component is set on the worktable and is used to adjust the position of the support frame. There are two synchronization frames, which are slidably connected to both ends of the support frame. The bottom of the connecting rod slides through the synchronization frame, and two connecting plates are slidably connected to the upper and lower surfaces of the synchronization frame, respectively. Through the provided support mechanism, multiple support mechanisms are provided to achieve the function of supporting and connecting the connecting rod.

[0018] A process for packaging LED chips includes the following steps:

[0019] Step 1: Place the fixture body on the workbench and align the four connection ports of the fixture body with the positions of the expansion blocks. Then, through the operation of the support mechanism, the four limit plates will drive the expansion blocks on them to move upward along the connection ports. While moving upward, the limit blocks will move synchronously under the connection of the guide components until the support mechanism stops moving. Then, the limit blocks and the limit plates will form an L shape on the fixture body.

[0020] Step 2: Place the FPC circuit board on the fixture body, with all four corners of the FPC circuit board located inside the four sets of L-shaped limiting blocks and limiting plates to position the FPC circuit board.

[0021] Step 3: The magnetic steel sheet is fitted onto the outside of the four support blocks through the four corner mounting holes. At this time, the magnetic steel sheet is located directly above the FPC circuit board. As the support mechanism moves, the limiting plate moves down and the magnetic steel sheet is tightened and opened. As the support mechanism continues to move, the magnetic steel sheet is placed vertically and stably on the FPC circuit board, and the gold-plated probe on the PFC circuit board is precisely exposed. At the same time, the magnetic steel sheet is attracted and fixed to the fixture body.

[0022] Step 4: Place the assembled fixture body into the die bonder and invert and transfer at least three LED chips (red, green, and blue) and one driver chip (IC) onto the substrate assembly to form a pixel unit;

[0023] Step 5: Etch the electrode positions of the matrix pixel units on the FPC circuit board;

[0024] Step 6: Mount the module on the FPC circuit board according to the preset dimensions of the matrix display module;

[0025] Step 7: Apply adhesive to the surface of the matrix LED display module to complete die bonding;

[0026] Step 8: The die-bonded FPC circuit board is then reflow soldered using a wire bonding machine;

[0027] Step 9: Place the cooled and welded fixture body back onto the workbench. Then, by connecting the alignment mechanism and the support mechanism, make the magnetic steel sheet detach vertically from the FPC circuit board, and then remove the FPC circuit board.

[0028] Step 10: Then, the FPC circuit board is coated with adhesive using a packaging machine.

[0029] The present invention has at least the following beneficial effects:

[0030] 1. When using this invention, a worktable is provided at the entrance of the die bonder body, and a connection alignment mechanism is provided on the worktable. When packaging process lamp beads, the fixture body is first placed on the worktable. Then, the connection alignment mechanism is located at the four connection ports and performs preliminary positioning of the FPC circuit board. At the same time as positioning, the magnetic steel sheet can be supported and lifted. Then, the magnetic steel sheet can be placed vertically and stably on the fixture body, and the FPC circuit board is pressed. This avoids wear on the gold plating layer on the FPC circuit board, thereby ensuring the accuracy of chip die bonding position and packaging.

[0031] 2. The connection alignment mechanism, support mechanism, and fixing mechanism in this invention not only achieve stable connection of the magnetic steel sheet, but also, after the FPC circuit board completes reflow soldering, the connection alignment mechanism enables the magnetic steel sheet to be vertically and stably detached from the FPC circuit board, while preventing deformation of the magnetic steel sheet, further ensuring the accuracy of subsequent chip packaging.

[0032] 3. The support mechanism and fixing mechanism in this invention can not only assist in picking up and placing the magnetic steel sheet, but also facilitate the workers to pick up and place the tool body, thereby facilitating the workers to move the tool body. Attached Figure Description

Detailed Implementation

[0048] 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.

[0049] Example 1

[0050] Please see Figure 1A process lamp bead packaging device includes a fixture body 1 for supporting an FPC circuit board, a die bonder body 2 for fixing chips onto the FPC circuit board, a wire bonding machine 3 for soldering the die bonded FPC circuit board, and a packaging machine 4 for packaging the FPC circuit board.

[0051] Please see Figures 1 to 6 The die bonder body 2 has a worktable 5 at its entrance. The worktable 5 is used to support the fixture body 1. The worktable 5 has two openings 51, and both ends of the openings 51 are equipped with a connection and alignment mechanism 6. The connection and alignment mechanism 6 is used to sequentially align and connect the PFC circuit board and the magnetic steel sheet on the fixture body 1. The fixture body 1 has a connection port 11 corresponding to the connection and alignment mechanism 6.

[0052] The workbench 5 is equipped with a support mechanism 7, which is used to connect the alignment mechanism 6. The workbench 5 is also equipped with a fixing mechanism 8, which is used to position the support mechanism 7. The fixing mechanism 8 and the support mechanism 7 cooperate with each other.

[0053] Please see Figures 10 to 14 The alignment mechanism 6 includes a transverse bearing shell 61, a synchronous adjustment member 62, a first vertical connecting shell 63, a second vertical connecting shell 64, a support shell 65, and a limiting stop member 9. The transverse bearing shell 61 is connected to the fixing mechanism 8. The synchronous adjustment member 62 is disposed on the transverse bearing shell 61 and is used to connect the first vertical connecting shell 63 and the second vertical connecting shell 64.

[0054] As a supplementary explanation, the synchronous adjustment component 62 includes a first bidirectional threaded screw rotatably connected inside the transverse bearing shell 61, and a handle is fixedly installed at one end of the first bidirectional threaded screw. Two bearing blocks are slidably connected inside the transverse bearing shell 61, and the two bearing blocks are threadedly sleeved on the first bidirectional threaded screw. The first vertical connecting shell 63 and the second vertical connecting shell 64 are respectively fixedly installed on the two bearing blocks.

[0055] Specifically, when adjusting the position of the first vertical connecting shell 63 and the second vertical connecting shell 64 relative to the transverse bearing shell 61, the first bidirectional threaded screw is rotated by turning the handle. When the first bidirectional threaded screw rotates, it provides driving forces in opposite directions to the two bearing blocks. At the same time, under the limiting action of the transverse bearing shell 61, the first vertical connecting shell 63 and the second vertical connecting shell 64 are further moved in opposite directions, thereby achieving the function of adjusting the distance between the first vertical connecting shell 63 and the second vertical connecting shell 64.

[0056] Please see Figures 7 to 8There are four support shells 65. Each of the four support shells 65 is fixedly connected to one side of a support block 66. The four support blocks 66 are distributed in pairs at the first vertical connecting shell 63 and the second vertical connecting shell 64. That is, two support blocks 66 slide through the first vertical connecting shell 63, and the other two support blocks 66 slide through the second vertical connecting shell 64. An adjustment member 67 is provided at the first vertical connecting shell 63, and the adjustment member 67 is used to adjust the two support blocks 66 thereon.

[0057] As a supplementary explanation, the adjusting component 67 includes a second bidirectional threaded screw and a rotating block. The second bidirectional threaded screw is rotatably connected inside the support shell 65, and one end of the second bidirectional threaded screw is fixedly connected to the rotating block. The support block 66 located at the first vertical connecting shell 63 is threadedly sleeved on the outside of the two second bidirectional threaded screws.

[0058] Specifically: When adjusting the position of the two support shells 65 on the two first vertical connecting shells 63, the rotating block is rotated, which further rotates the second bidirectional threaded screw. When the second bidirectional threaded screw rotates, it provides driving force in opposite directions to the two support blocks 66. Due to the limiting effect of the first vertical connecting shells 63, the two support blocks 66 move in opposite directions, thereby further adjusting the distance between the two support shells 65 on the two support blocks 66.

[0059] Synchronization elements are provided at the two support shells 65 between the adjacent first vertical connecting shell 63 and second vertical connecting shell 64;

[0060] As a supplementary explanation, the synchronizing component includes a connecting frame, and there are two connecting frames. The two connecting frames are fixedly connected to the outer walls of the two support shells 65 at the first vertical connecting shell 63, and the two connecting frames are respectively slidably sleeved on the outside of the two support shells 65 located at the second vertical connecting shell 64.

[0061] Furthermore, when the positions of the support shells 65 on the first vertical connecting shell 63 and the second vertical connecting shell 64 are adjusted synchronously;

[0062] When the two supporting shells 65 at the first vertical connecting shell 63 move synchronously, the two supporting shells 65 at the second vertical connecting shell 64 move synchronously and adjust under the connection of the connecting frame.

[0063] Limiting stops 9 are mounted on the support housing 65, and the support mechanism 7 is connected to multiple limiting stops 9.

[0064] Please see Figures 10 to 14The limiting stop 9 includes a limiting plate 91, a connecting member 92, a supporting member 93, a limiting block 94, and a guide member 95. The top of the support shell 65 is provided with a moving port. The limiting plate 91 slides through the moving port and the connecting port 11. The connecting member 92 is provided at the bottom of the limiting plate 91, and the connecting plate 922 is connected to the support mechanism 7.

[0065] The top of the limiting plate 91 is provided with a slot 911, and the supporting member 93 is located at the slot 911. The positioning plate 96 is fixedly installed on the outside of the support shell 65, and the positioning plate 96 is connected to the supporting member 93. The limiting block 94 is located on the upper surface of the fixture body 1, and the guide member 95 is arranged between the limiting block 94 and the limiting plate 91.

[0066] The connector 92 includes a connecting rod 921 and a connecting plate 922. The connecting rod 921 is fixedly installed at the bottom of the limiting plate 91, and the bottom of the connecting rod 921 extends to the support mechanism 7. There are two connecting plates 922, and both connecting plates 922 are fixedly installed at the bottom of the connecting rod 921.

[0067] The support shell 65 is provided with an L-shaped groove 651 at the position corresponding to the guide member 95, and the limiting plate 91 is provided with an inclined groove 912 at the position corresponding to the guide member 95. The guide member 95 includes a first guide rod 951 and a second guide rod 952. The first guide rod 951 slides through the L-shaped groove 651 and the inclined groove 912 respectively. One end of the second guide rod 952 is fixedly connected to the first guide rod 951, and the other end of the second guide rod 952 is fixedly connected to the limiting block 94.

[0068] The expansion member 93 includes an expansion block 931, a connecting rod 932, a sliding rod 933, a buffer spring 934, an inclined block 935, and a pressing member 936. The expansion block 931 slides through the top of the slot 911. One end of the connecting rod 932 is rotatably connected to the bottom of the expansion block 931 via a pin, and the other end of the connecting rod 932 is rotatably connected to a connecting seat 937 via a pin. The connecting seat 937 is fixedly installed on the top of the sliding rod 933. The buffer spring 934 is sleeved on the outside of the sliding rod 933, and both ends of the buffer spring 934 are fixedly connected to the inner wall of the slot 911 and the inclined block 935, respectively. The inclined block 935 is fixedly installed on the bottom of the sliding rod 933. The pressing member 936 is located at the bottom of the slot 911. A support opening 952 is provided on the support shell 65 at the position corresponding to the pressing member 936.

[0069] The extrusion component 936 includes a connecting spring 9361, an extrusion block 9362, an extrusion rod 9363, and a contact block 9364. One end of the connecting spring 9361 is fixedly installed on the inner wall of the slot 911, and the other end of the connecting spring 9361 is fixedly connected to the extrusion block 9362. There are two extrusion rods 9363, both of which slide through the support opening 952 and the slot 911. One end of the two extrusion rods 9363 is fixedly connected to the extrusion block 9362, and the other end of the two extrusion rods 9363 is fixedly connected to the contact block 9364. The contact block 9364 is slidably connected to the positioning plate 96. In this application, the positioning plate 96 is L-shaped, that is, one end of the positioning plate 96 is a blocking end, and the other end is a connecting end. The connecting end is fixedly connected to the outer surface of the support shell 65, and the blocking end is provided with a blocking slope. The blocking slope is used to extrude and position the contact block 9364.

[0070] Specific implementation process: Before the process lamp beads are packaged, the fixture body 1 is first placed on the workbench 5, and the four connection ports 11 of the fixture body 1 are aligned with the four support blocks 931 respectively. The width of the support blocks 931 in this application is the same as the width of the connection ports 11. This setting ensures that the support blocks 931 can move vertically upward while the fixture body 1 can be further positioned.

[0071] Subsequently, the operation of the support mechanism 7 causes the four connecting rods 921 to move vertically upward relative to the inside of the support shell 65. As the connecting rods 921 move vertically upward, they push the limiting plate 91 to move vertically upward. As the limiting plate 91 moves upward, the first guide rod 951 drives the second guide rod 952 to move upward, thereby causing the limiting block 94 at the second guide rod 952 to move upward.

[0072] Because of the limiting effect of the L-shaped groove 651 of the support shell 65 and the inclined groove 912 of the limiting plate 91, when the limiting block 94 moves to the upper surface of the connection port 11 of the fixture body 1 along with the limiting plate 91, under the limiting effect of the other end of the L-shaped groove 651, as the limiting plate 91 continues to move upward, the limiting block 94 moves along the direction deviating from the connection port 11 until the limiting plate 91 stops moving. Then, the limiting plate 91 and the limiting block 94 form an L-shaped vertical angle distribution on the fixture body 1. At this time, the operator can place the FPC circuit board between the four limiting plates 91 and the limiting block 94, thereby achieving the function of positioning the FPC circuit board.

[0073] Furthermore, since the supporting blocks 931 on the limiting plate 91 are located relative to the top of the limiting plate 91, the positions of the four corner mounting holes of the magnetic steel sheet are fitted onto the outside of the four supporting blocks 931. At the same time, the four corners of the magnetic steel sheet are all located on the upper surface of the limiting plate 91. At this time, the support mechanism 7 moves down, which further causes the four connecting rods 921 to move down synchronously. The connecting rods 921 then drive the limiting plate 91 to move down. When the limiting plate 91 moves down, due to the limiting and squeezing of the contact block 9364 by the blocking inclined surface of the positioning plate 96, the squeezing rod 9363 further drives the squeezing block 9362 to move along the inside of the slot 911. And when the squeezing block 9362 moves down, the squeezing block 9362 moves along the inside of the slot 911. While 362 is moving, it squeezes the inclined block 935, and the inclined block 935 pushes the connecting support rod 932 through the sliding rod 933. The connecting support rod 932 then pushes the opening block 931 further. At this time, the four opening blocks 931 move outward relative to the mounting hole, thereby further tightening the magnetic steel sheet. This allows the thin magnetic steel sheet to be tightened and placed vertically and stably on the FPC circuit board, ensuring that the gold-plated probe on the PFC circuit board is accurately exposed. After the magnetic steel sheet is stably attached to the fixture body 1, the limiting plate 91 and the limiting block 94 move into the support shell 65.

[0074] Meanwhile, when the magnetic steel sheet is removed, the four connection ports 11 of the fixture body 1 are first aligned with the support block 931. Then, through the operation of the support mechanism 7, the magnetic steel sheet is further lifted vertically upwards from the surface of the FPC circuit board.

[0075] The fixing mechanism 8 includes a fixed base 81, a fixing rod 82 and a pushing member 83. The pushing member 83 is installed at the bottom inside the workbench 5, and one end of the pushing member 83 is fixedly connected to the fixed base 81. The fixing rod 82 is fixedly installed on the fixed base 81, and the transverse bearing shell 61 is fixedly installed on the top of the fixing rod 82. The support mechanism 7 is sleeved on the outside of the fixing rod 82.

[0076] As a supplementary explanation, the pusher 83 includes a first electric push rod 831 and a pusher frame 832. The first electric push rod 831 is fixedly installed at the bottom of the workbench 5, and the output end of the first electric push rod 831 is fixedly connected to the pusher frame 832. The pusher frame 832 is fixedly connected to the fixed base 81.

[0077] Please see Figure 6 and Figure 9The support mechanism 7 includes a support frame 71, a mating part 72, and a synchronization frame 73. The support frame 71 is slidably sleeved on the outside of the fixed rod 82, and the mating part 72 is set on the workbench 5. The mating part 72 is used to adjust the position of the support frame 71. There are two synchronization frames 73, which are slidably connected to both ends of the support frame 71. The bottom of the connecting rod 921 slides through the synchronization frame 73, and two connecting plates 922 are slidably connected to the upper and lower surfaces of the synchronization frame 73, respectively.

[0078] As a supplementary explanation, the mating component 72 includes a second electric push rod 721, a mating plate 722, a support shaft 723, a guide shaft 724, and a moving block 725. The second electric push rod 721 is rotatably connected to the outside of the worktable 5.

The moving block 725 is provided with a sliding groove, and one end of the guide shaft 724 slides through the sliding groove. The worktable 5 is provided with an external opening corresponding to the position of the moving block 725, and the moving block 725 slides through the external opening and is fixedly connected to the support frame 71.

[0079] Specific implementation process: In this application, when the four connecting rods 921 are moved vertically upward or downward, the second electric push rod 721 is operated, thereby causing the mating plate 722 to rotate relative to the support shaft 723. While the mating plate 722 is rotating, the moving block 725 is driven through the guide shaft 724. Under the limiting action of the fixed rod 82, the support frame 71 moves upward or downward relative to the fixed rod 82.

[0080] Meanwhile, in this application, when it is necessary to remove the fixture body 1 from the workbench 5, the first electric push rod 831 is operated, thereby causing the four supporting blocks 931 to move laterally relative to the two openings 51. At the same time, the four supporting blocks 931 are deviated from the connection port 11. Subsequently, the second electric push rod 721 moves in coordination, thereby causing the four supporting blocks 931 to lift the fixture body 1 synchronously, thus facilitating the handling of the fixture body 1.

[0081] Example 2

[0082] Please see Figures 1 to 6 A process for packaging LED chips includes the following steps:

[0083] Step 1: Place the fixture body 1 on the workbench 5, and align the four connection ports 11 of the fixture body 1 with the positions of the supporting blocks 931. Then, through the operation of the support mechanism 7, the four limiting plates 91 will drive the supporting blocks 931 on them to move upward along the connection ports 11. At the same time, the limiting blocks 94 will move synchronously under the connection of the guide 95 until the support mechanism 7 stops moving. Then the limiting blocks 94 and the limiting plates 91 will form an L shape on the fixture body 1.

[0084] Step 2: Place the FPC circuit board on the fixture body 1, with the four corners of the FPC circuit board located inside the four sets of L-shaped limiting blocks 94 and limiting plates 91 to position the FPC circuit board.

[0085] Step 3: The magnetic steel sheet is fitted onto the outside of the four support blocks 931 through the four corner mounting holes. At this time, the magnetic steel sheet is located directly above the FPC circuit board. As the support mechanism 7 moves, the limiting plate 91 moves down and the magnetic steel sheet is stretched and stretched. As the support mechanism 7 continues to move, the magnetic steel sheet is placed vertically and stably on the FPC circuit board, and the gold-plated probe on the PFC circuit board is accurately exposed. At the same time, the magnetic steel sheet is attracted and fixed to the fixture body 1.

[0086] Step 4: Place the assembled fixture body 1 into the die bonder and invert and transfer at least three LED chips (red, green, and blue) and one driver chip (IC) onto the substrate assembly to form a pixel unit;

[0087] Step 5: Etch the electrode positions of the matrix pixel units on the FPC circuit board;

[0088] Step 6: Mount the module on the FPC circuit board according to the preset dimensions of the matrix display module;

[0089] Step 7: Apply adhesive to the surface of the matrix LED display module to complete die bonding;

[0090] Step 8: The die-bonded FPC circuit board is reflow soldered using wire bonder 3;

[0091] Step 9: Place the cooled and welded fixture body 1 back onto the workbench 5. Then, by connecting the alignment mechanism 6 and the support mechanism 7, the magnetic steel sheet is vertically lifted off the FPC circuit board, and the FPC circuit board is removed.

[0092] Step 10: Then, the FPC circuit board is coated with adhesive using the encapsulation machine 4.
