Abstract
Description
Technical Field
[0001] This invention relates to the field of crimping technology, and more particularly to an automatic crimping device. Background Technology
[0002] A microlight-emitting diode (Micro LED) chip is a novel LED structure obtained by thinning, miniaturizing, and arraying the original LED structure. It integrates arrayed micron-sized LED units onto an active-addressable driver panel to achieve the lighting and individual control of each LED unit. Connecting the microLED chip to a flexible circuit board forms a microLED display panel.
[0003] During the production of miniature LED display panels, testing equipment is used for inspection. This equipment integrates a crimping carrier to press the external interface of the miniature LED display panel against the probes on the carrier, thus performing a lighting test. Currently, the industry commonly uses manual crimping carriers, where the external interface of the miniature LED display panel is crimped against the probes manually. Because both the external interface of the miniature LED display panel and the probes of the crimping carrier are delicate components, the connection must be performed slowly and carefully, which is time-consuming and labor-intensive, resulting in low production efficiency.

[0094] like Figure 1 As shown, an automatic crimping device includes: a support platform 101, a crimping assembly, multiple flexible circuit boards 20, a vision alignment assembly, a sample moving device, and a control device.
[0095] The support platform 101 is used to support the structure to be tested, which is a miniature light-emitting diode display panel. For example... Figure 2 As shown, in one embodiment of the present invention, the support platform 101 has a window in the middle, and a transparent carrier plate 102 is provided at the window to support the carrier plates loaded with multiple structures to be tested, while facilitating the acquisition of images by the vision alignment component.
[0096] In one embodiment of the present invention, two substrates 103 are disposed on the support platform 101, the two substrates 103 being arranged opposite to each other and distributed at the left and right edges of the support platform 101. Testing equipment is externally connected to the substrates 103.
[0097] In one embodiment of the present invention, the first ends of a plurality of flexible circuit boards 20 are electrically connected to a substrate 103, and the second ends are fixedly connected to a pressing assembly.

[0098] In one embodiment of the present invention, such as Figure 1 As shown, the automatic crimping equipment also includes a support frame 104, and a support platform 101 is fixed on the support frame 104. Figure 3 As shown, the support frame 104 has a clearance window 1041, which is located below the transparent carrier plate 102, and the length and width of the clearance window 1041 are greater than the length and width of the transparent carrier plate 102 in order to expose the transparent carrier plate 102.
[0099] In one embodiment of the present invention, such as Figure 4As shown, the automatic crimping equipment also includes a temporary storage stage 105, which is mounted on a support frame 104 for storing a sample loaded with the structure to be tested. At the start of crimping, a sample moving device removes the sample from the temporary storage stage 105. The temporary storage stage 105 has a storage slot 1051 for storing the sample. The shape and size of the storage slot 1051 are the same as or slightly larger than the shape and size of the sample, so that the sample can be placed precisely into the storage slot 1051.

[0101] Figure 7 A side view schematic diagram of a second support structure according to an embodiment of the present invention is shown; Figure 8 A schematic diagram of a pressure head adjustment assembly according to an embodiment of the present invention is shown; Figure 9 A schematic diagram of a flexible circuit board and a crimp connector according to an embodiment of the present invention is shown.
[0102] In one embodiment of the present invention, two sets of crimping assemblies are disposed on the left and right sides of the support platform 101. For example... Figure 1 As shown, the crimping assembly includes an up-and-down moving device 201, a rotating support structure 202, a crimping rod 203, a crimping head 204, a rotating support assembly, and a crimping head adjustment assembly.
[0103] In one embodiment of the present invention, such as Figure 1 As shown, the up-and-down moving device 201 is fixedly connected to the rotating support structure 202, and the support structure 202 is movably connected to the crimping rod 203. The up-and-down moving device 201 applies pushing and pulling forces to the crimping rod 203 to rotate the crimping rod 203 up and down, thereby driving the crimping joint 204 to move up and down.
[0104] In one embodiment of the present invention, the vertical moving device 201 is a cylinder. The cylinder includes a cylinder body and an output shaft, and the cylinder body can drive the output shaft to move up and down. The rotary support structure 202 is fixedly connected to the output shaft of the cylinder, and the output shaft can drive the rotary support structure 202 to move up and down. In other embodiments of the present invention, the vertical moving device 201 can also be a motor.
[0105] In one embodiment of the present invention, such as Figure 1As shown, the first end of the crimping rod 203 is movably connected to the rotary support structure 202, and the second end of the crimping rod 203 is fixedly connected to the crimping head 204. The rotary support structure 202 is configured to drive the first end of the crimping rod 203 to rotate. Furthermore, the first end of the crimping rod 203 and the rotary support structure 202 can be connected by a pin.
[0106] In one embodiment of the invention, the crimping rod 203 is provided with a pin hole (not shown) adjacent to the second end of the crimping rod 203.
[0107] In one embodiment of the present invention, such as Figure 1 As shown, the rotary support assembly is mounted on the bearing platform 101 and is movably connected to the crimping rod 203. The rotary support assembly is configured to provide a rotation shaft to the second end of the crimping rod 203. The second end of the crimping rod 203 can rotate up and down relative to the rotary support assembly so as to drive the crimping joint to move up and down.
[0108] The crimping rod 203 rotates up and down relative to the rotating support structure 202 and the rotating support assembly to drive the crimping connector 204 to move up and down. The crimping connector 204 is configured to crimp and fix the external interface of the structure under test to the crimping interface of the flexible circuit board 20 by applying pressure to the structure under test.
[0109] In one embodiment of the present invention, such as Figure 1 and 5 As shown, the rotating support assembly includes a first support structure 205 and a second support structure 206. The first support structure 205 is disposed on the bearing platform 101, and the second support structure 206 is fixedly connected to the first support structure 205. The first support structure 205 is configured to provide a sliding track for the support pressure head adjustment assembly. The second support structure 206 is movably connected to the pressing rod 203, providing a rotation axis to the second end of the pressing rod 203, which can rotate up and down relative to the second support structure 206. Further, the second support structure 206 has a pin hole (not shown), and the pressing rod 203 is connected to the second support structure 206 by a pin 30, with the pin 30 adjacent to the second end of the pressing rod 203 compared to the first end.
[0110] like Figure 6 As shown, the first support structure 205 has a first clearance opening 2051 for accommodating the pressing rod and multiple flexible circuit boards 20. Figure 7 As shown, the second support structure 206 has a second clearance opening 2061 for accommodating the crimping rod and multiple flexible circuit boards 20. The first and second clearance openings allow for a better layout of the positional relationship between the first support structure, the second support structure, and the crimping rod, resulting in a more compact overall structure for the automatic crimping equipment.
[0111] In one embodiment of the present invention, the pressure head adjusting assembly is slidably connected to the first support structure 205. The pressure head adjusting assembly is fixedly connected to the pressure head 204.
[0112] like Figure 1 and 8 As shown, the pressure head adjustment assembly includes multiple adjustment rods 207 and an adjustment structure body 208. The multiple adjustment rods 207 pass through the adjustment structure body 208, and the multiple adjustment rods 207 are adjustablely connected to the adjustment structure body 208, for example, by a threaded connection.
[0113] The first ends of multiple adjusting rods 207 are fixedly connected to the crimping joint 204. The distance between the crimping joint 204 and the bearing platform 101 is adjusted by moving the multiple adjusting rods 207 up and down in the main body of the adjusting structure 208.
[0114] The adjusting rod 207 can rotate within the adjusting structure body 208 to adjust the distance between the crimping head 204 and the bearing platform 101, thereby adjusting the crimping head 204 to a suitable position and preventing the crimping head 204 from damaging the product or failing to contact the product during the crimping process.
[0115] The main body of the adjusting structure 208 is slidably connected to the first support structure 205, so that the crimping joint 204 can move up and down.
[0116] In one embodiment of the invention, each of the second ends of a plurality of adjusting rods 207 is provided with an adjusting head (not shown), which is used to adjust the vertical movement of the adjusting rods 207 within the adjusting structure body 208. Further, the adjusting head may be, for example, a nut, which is fixedly connected to the adjusting rod 207, for example, by welding. The adjusting rod 207 is adjusted by turning the adjusting head using an adjusting tool similar to a wrench. Additionally, the adjusting element may be integrally formed with the adjusting rod 207, similar to a bolt head, with the adjusting rod 207 acting as a screw.
[0117] In one embodiment of the present invention, the pressure head adjustment assembly further includes a top concealment structure 209, in which multiple adjustment heads are located. The top concealment structure 209 is used to conceal the adjustment heads to prevent them from being exposed and affecting the aesthetics.
[0118] The top concealed structure 209 has multiple through holes and multiple grooves communicating with the through holes. The second end of the adjusting rod 207 is located in the through hole of the top concealed structure 209, and the adjusting head is located in the groove. The size of the groove is larger than the size of the adjusting head so that the adjusting tool can turn the adjusting head.
[0119] The adjusting rod 207 can rotate within the through hole of the top concealed structure 209. The diameter of the second end of the adjusting rod 207 is smaller than the diameter of the main body of the adjusting rod 207. The diameter of the through hole of the top concealed structure 209 is larger than the diameter of the second end of the adjusting rod 207 but smaller than the diameter of the main body of the adjusting rod 207, so that the second end of the adjusting rod 207 can rotate within the through hole of the top concealed structure 209 without the top concealed structure 209 falling down.
[0120] During crimping, the up-and-down moving device 201 pushes the rotating support structure 202 upward. Based on the lever principle, the second end of the crimping rod 203 rotates downward relative to the second support structure 206, causing the crimping head 204 to press down. The downward pressing of the crimping head 204 causes the pressure head adjusting component to slide downward. When the up-and-down moving device 201 pulls the rotating support structure 202 downward, the second end of the crimping rod 203 rotates upward relative to the second support structure 206, causing the crimping head 204 to lift. The lifting of the crimping head 204 causes the pressure head adjusting component to slide upward.
[0121] In one embodiment of the present invention, such as Figure 1 , 4 As shown in Figure 9, a pressure head adhesive strip 2041 is provided on the lower surface of the crimp connector 204. The back sides of the second ends of the plurality of flexible circuit boards 20 are fixedly connected to the pressure head adhesive strip 2041. Furthermore, a portion of each flexible circuit board 20 is fixed to the lower surface of the crimp connector 204 by a fixing plate 211, indirectly ensuring the stability of the connection between the pressure head adhesive strip 2041 and the flexible circuit board 20.
[0122] In one embodiment of the present invention, such as Figure 9 As shown, a crimping interface 200 is provided on the front side of the second end of the flexible circuit board 20, and the crimping interface 200 includes multiple probes. The crimping interface 200 is located on the lower surface of the flexible circuit board 20 and is used for electrical connection to the structure under test.
[0123] In one embodiment of the present invention, such as Figure 1 As shown, the crimping assembly also includes a mounting bracket 210. The vertical moving device 201 is mounted on the mounting bracket 210.

[0125] In one embodiment of the present invention, such as Figure 1As shown, the vision alignment component is positioned below the support platform 101 and below the transparent carrier plate 102. The vision alignment component is used to acquire images of the carrier plate carrying the structure to be tested on the transparent carrier plate and transmit the images to the control device to determine whether the carrier plate is placed correctly.
[0126] like Figure 1 As shown, the visual alignment component includes multiple cameras 301 and a magnifying glass 302 located above the cameras 301. In one embodiment of the invention, the visual alignment component includes four cameras 301 and four magnifying glasses 302, with a magnifying glass 302 positioned directly above each camera 301.

A camera 301 is fixed to a camera mount 303, a magnifying glass mount 304 is disposed on a camera mount 303, and a magnifying glass 302 is fixed to a magnifying glass mount 304.
[0128] The number of camera mounts 303 and magnifying glass mounts 304 is the same as the number of cameras 301 and magnifying glasses 302, respectively.

[0134] like Figure 1 and 12 As shown, the sample moving device is located above the support platform. The sample moving device is used to transfer the sample containing the structure to be tested between the temporary storage stage and the support platform. The sample moving device includes a rotation adjustment structure 501, an XY movement module 502, and an adsorption fixing structure 503.
[0135] In one embodiment of the present invention, the rotation adjustment structure 501 includes a rotary motor 5011 and an output shaft 5012, the output shaft 5012 being connected to the adsorption fixing structure 503.
[0136] In one embodiment of the present invention, the adsorption fixation structure 503 includes a vacuum body 5031 and a plurality of adsorption ports 5032. The vacuum body has a vacuum cavity inside, and the plurality of adsorption ports 5032 are disposed on the vacuum body 5031 and communicate with the vacuum cavity. The adsorption ports 5032 are used to adsorb and fix a substrate loaded with the structure to be tested. Further, the adsorption ports 5032 adsorb blank areas on the substrate where the structure to be tested is not loaded.
[0137] In one embodiment of the present invention, the adsorption fixation structure 503 further includes a vacuum connector (not shown) which communicates with the vacuum cavity of the vacuum body and is configured to be connected to an external negative pressure device.
[0138] Furthermore, the vacuum body is shaped like a square ring.
[0139] In one embodiment of the present invention, the XY moving module 502 is fixedly connected to the rotation adjustment structure 501. The XY moving module 502 enables the rotation adjustment structure 501 to move back and forth and left and right, thereby driving the adsorption fixing structure 503 to move back and forth and left and right.
[0140] In one embodiment of the present invention, the XY moving module 502 and the rotation adjustment structure 501 are fixedly connected by a connecting plate 504. Further, a mounting hole is provided at the first end of the connecting plate 504, the rotation adjustment structure 501 is mounted at the first end of the connecting plate 504, the output shaft 5012 is placed in the mounting hole, and the XY moving module 502 is fixed at the second end of the connecting plate 504.
[0141] The XY moving module 502 includes an X module 5021 and a Y module 5022 mounted on the upper surface of the X module. A connecting plate 504 is fixedly connected to the X module 5021. The X module 5021 is used to move the adsorption and fixing structure 503 along the X-axis (left-right movement), and the Y module 5022 is used to move the adsorption and fixing structure 503 along the Y-axis (back-forward movement). The X module 5021 and Y module 5022 are powered by drive motors.
[0142] In one embodiment of the invention, the automatic crimping device further includes a moving device mounting bracket (not shown), on which the sample moving device is fixed, such that the adsorption fixing structure 503 is positioned above the support platform. The adsorption fixing structure 503 can move back and forth and left and right under the drive of the XY moving module 502, transferring the sample between the support platform and the temporary storage stage.
[0143] In one embodiment of the present invention, the control device is electrically connected to the vision alignment component, the sample moving device, and the pressing component. Further, the control device is electrically connected to the camera 301, the rotation adjustment structure 501, the XY movement module 502, and the vertical movement device 201.
[0144] The control device receives the image acquired by the camera of the vision alignment component and determines whether the slide is placed correctly. When it is placed correctly, it instructs the up-and-down moving device 201 of the pressing component to press. If it is not placed correctly, the control device controls the rotation adjustment structure 501 and / or the XY moving module 502 of the sample moving device to adjust the placement position of the slide.
[0145] Figure 13 A top view of a support platform according to another embodiment of the present invention is shown; Figure 14 A front view schematic diagram of a portion of the structure of a crimping assembly according to another embodiment of the present invention is shown.
[0146] In another embodiment of the invention, such as Figure 13 and 14 As shown, the support platform 101 has a window in the middle, and a transparent carrier plate 102 is provided at the window. Two substrates 103 are provided on the support platform 101 and are located on both sides of the transparent carrier plate 102.
[0147] Multiple flexible circuit boards 20 are fixed to the support platform 101 with their front ends facing upwards. The first end of each flexible circuit board 20 is electrically connected to the substrate 103, and the second end is located on the transparent carrier plate 102. The front end of the second end of each flexible circuit board 20 has a crimping interface 200, which includes multiple probes.
[0148] In another embodiment of the invention, a plurality of flexible circuit boards 20 are fixed to the support platform 101 by a fixing plate 211. The back side of the second end of the flexible circuit board 20 is bonded to the transparent carrier plate 102.
[0149] In another embodiment of the invention, such as Figure 14 As shown, the lower surface of the crimp connector 204 is provided with a crimp head rubber strip 2041. The lower surface of the crimp connector 204 also has a clearance groove 2042 for avoiding the fixing plate 211.
[0150] The crimping process using the aforementioned automatic crimping equipment is as follows:
[0151] Manually place the substrate containing the structure to be tested into the storage slot 1051 of the temporary storage stage 105.
[0152] The control device controls the up-and-down moving device 201 to pull down the rotating support structure 202 and the pressing rod 203. The pressing rod 203 will rotate upward relative to the rotating support structure 202 and the second support structure 206, causing the pressing joint 204 to be lifted.
[0153] The control device controls the sample moving device to adsorb and transfer the slide onto the transparent carrier plate 102 of the support platform 101. When transferring the slide from the temporary storage stage 105 to the support platform 101, the adsorption and fixing structure 503 and the slide enter from the side, transferring the slide onto the support platform 101. The adsorption and fixing structure 503 moves above the support platform 101 through the gap between the two pressure joints 204, and the slide adsorbed by the adsorption and fixing structure 503 moves from the gap between the pressure joints 204 and the support platform 101 onto the support platform 101.
[0154] The camera of the vision alignment component acquires an image of the substrate and transmits it to the control device, which determines whether the substrate is correctly positioned based on the image. If the substrate is incorrectly positioned, the control device adjusts the substrate's position by rotating the adjustment structure 501 and / or the XY movement module 502 according to the image command.
[0155] If the sample carrier is positioned correctly, the control device instructs the two vertical moving devices 201 to push the rotating support structure 202 and the pressing rod 203 upwards. The pressing rod 203 will then rotate downwards relative to the rotating support structure 202 and the second support structure 206, causing the pressing head 204 to press down. During the test, the sample moving device continuously holds the sample carrier.
[0156] After the test is completed, the control device instructs the up-and-down moving device 201 to pull down the rotating support structure 202 and the pressing rod 203. The pressing rod 203 will rotate upward relative to the rotating support structure 202 and the second support structure 206, causing the pressing joint 204 to lift. Finally, the control device instructs the sample moving device to transfer the sample on the transparent carrier plate 102 to the temporary storage stage 105, where it is manually removed.
[0157] While some embodiments of the present invention have been described in this application, those skilled in the art will understand that these embodiments are merely illustrative. Numerous variations, alternatives, and improvements will arise in those skilled in the art under the teachings of this invention without departing from its scope. The appended claims are intended to define the scope of the invention and thereby cover methods and structures within the scope of the claims themselves and their equivalents.
