Description

Technical Field

[0001] This invention relates to the field of notebook computer manufacturing technology, and in particular to a test plug-in / plug-out machine. Background Technology

[0002] In the field of laptop manufacturing technology, functional testing is performed on the external interfaces of laptops. Currently, most systems use automated insertion and removal equipment to perform the insertion and removal of test heads. Specifically, the laptop under test is usually located on a conveyor line, and a transfer structure moves the laptop to the testing station and positions it. Then, a fixture structure simulates manual clamping of the test head (plug) and performs insertion and removal operations on the interface under test. After the test is completed, the aforementioned transfer structure returns the tested laptop to the conveyor line. However, this method has the following problems: 1. In the zero-position state, the test head is placed on a positioning frame. To facilitate the transfer of the test head by the fixture structure, the positioning frame leaves a large gap when positioning the test head. This makes it easy for the test head to rotate or tilt accidentally during placement, which is detrimental to the accurate clamping of the test head by the fixture structure. 2. When the laptop is positioned on the testing platform, it is not always perfectly flat; sometimes it may be slightly tilted. The existing fixture structure does not have the function of correcting the angle of the test head, which can easily lead to insertion and removal failures. 3. During insertion and removal operations, there will be slight errors in the distance between each laptop and the fixture structure. If the same set moving distance is used for all insertions and removals of the test head, it will easily cause wear and tear on the external interface. At the same time, the fixture mechanism will also be damaged. 4. When each laptop is transferred to the testing station and positioned, the distance between it and the fixture mechanism is not always consistent. Without a corresponding structure to uniformly adjust the center position of the laptop, the fixture mechanism must observe the distance of the interface to be tested each time, calculate it, and move it adaptively. This will inevitably consume a lot of time and energy. 5. The same conveyor line handles both loading and unloading of laptops. Before a laptop completes testing, space needs to be reserved on the conveyor line for unloading, causing the next laptop to remain stationary for an extended period. Only after the previous laptop finishes testing will the next laptop be moved to the transfer station. This inevitably wastes considerable time, resulting in low production efficiency. Furthermore, using the same conveyor line for both loading and unloading can easily lead to confusion between untested and tested laptops, compromising production quality. 6. Transfer structures mostly use telescopic mechanisms to achieve movement. Currently, telescopic mechanisms often employ hydraulic cylinders, pneumatic cylinders, screw drives, chain drives, etc. When a large displacement is required, multiple telescopic mechanisms are needed. However, simply mechanically combining multiple telescopic mechanisms occupies a lot of space, hindering dimensional control and causing significant operational instability. Summary of the Invention

[0037] 1. In the test head fixture of the present invention, the two clamping members can stably clamp the test head body and prevent damage to the reference position for adjusting the angle of the test head body. By setting up an image acquisition device and an angle adjustment motor, the angle of the test head body can be adjusted according to the position of the interface to be tested. Then, the Z-axis robotic arm, Y-axis robotic arm, X-axis robotic arm and the insertion and removal drive device work together to complete the reliable insertion and removal operation of the test head. With the cooperation of the buffer rod, buffer elastic element and pressure sensor, it is possible to know whether the two clamping members have driven the test head to move reasonably, and damage to the test interface and test head under excessive movement can be reduced.

[0038] 2. In the test head positioning frame of the present invention, the cooperation of two positioning clamps and two positioning channels can not only stably position the test head body, but also facilitate the clamp to hold the test head body from the rear end and transfer it.

[0039] 3. In this invention, by cooperating with the centering component and the transfer component, the laptop computer to be tested can be centered at the initial position of the test station, which facilitates the movement of the fixture component with a uniform displacement. By cooperating with the centering component and the fixture component, the displacement of the fixture component in transferring the test head can be reduced, which helps to improve work efficiency.

[0040] 4. By setting up the loading and unloading conveyor components, the present invention can buffer the next laptop to be tested on the loading transfer section when the previous laptop to be tested is at the testing station. This can effectively reduce working time and improve production efficiency. In addition, the layered design of the loading and unloading conveyor lines makes it easy to distinguish between untested and tested laptops, which can effectively ensure the stability of production quality.

[0041] 5. In this invention, the insertion and cooperation of two sets of telescopic structures with two loading telescopic clearance ports and two unloading telescopic clearance ports easily enables the transfer of laptops between the loading station, processing and testing station, and unloading station. During the transfer process, the cooperation of the movable limiting plate and the fixed limiting plate can maintain the stability of the product as much as possible. Furthermore, the linkage design between the primary and secondary telescopic seats allows for bidirectional long-range telescopic displacement within a limited space to meet the distance requirements between the transfer support and the loading transfer section, the unloading transfer section, and the testing station.

[0054] To enable those skilled in the art to better understand the present invention, 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 embodiments described below are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments described in the present invention without creative effort are within the scope of protection of the present invention.

[0055] Example 1

[0056] like Figures 1 to 41As shown, the system includes a support platform 50, on which a plug-in unit 126 is mounted. The plug-in unit includes a transfer component 127, a centering component 128, a closing component 129, a clamping component 130, a loading and conveying component 131 for transferring the laptop computer to be tested, and a unloading and conveying component 132 for receiving the laptop computer that has been tested. The transfer component is used to place the laptop computer and realize the transfer of the laptop computer between the loading and conveying component, the testing station, and the unloading and conveying component.

[0057] The centering assembly includes two centering groups respectively arranged on both sides of the transfer assembly and a centering drive assembly for driving the two centering groups to move towards or away from each other. The centering group includes a centering reference frame 59, and a plurality of test head positioning frames 60 are provided on the outer end of the centering reference frame 59. The outer end of the test head positioning frame 60 has two spaced positioning clamps 83.

[0058] The fixture assembly includes two sets of fixtures respectively disposed on both sides of the transfer assembly. Each fixture set includes a Z-axis robotic arm 70 and a Y-axis robotic arm 72 connected to the output end of the Z-axis robotic arm 70. The output end of the Y-axis robotic arm 72 is connected to an X-axis support 73. An X-axis robotic arm 71 is mounted on the X-axis support 73. The output end of the X-axis robotic arm 71 is connected to an X-axis mounting base 74. The X-axis mounting base 74 is equipped with a plug-in / plug-out drive device 75 and a data acquisition mounting frame 120. An image acquisition device 78 is mounted on the data acquisition mounting frame 120. The output end of the plug-in / plug-out drive device 75 is connected to an X-axis connector 76. An angle adjustment motor 77 is provided on the X-axis connecting seat 76. The angle adjustment motor 77 has a hollow output shaft. The inner end of the output shaft is connected to a gripper cylinder 57 for clamping the test head. The gripper cylinder 57 has two gripper output ends that can move in opposite directions or back to back. Both gripper output ends are connected to a clamping member 79. The working surfaces of the two clamping members 79 are provided with a limit notch 124, a clamping section groove 80 and a limit section groove 81 with a groove depth greater than that of the clamping section groove 80. The bottom of the clamping section groove 80 extends to the bottom end to provide a clamping section limit groove 107.

[0059] The test head applicable to this embodiment includes a test head body 113. The inner end of the test head body 113 has an insertion section 114. The bottom end of the test head body 113 is provided with a wiring section 115 connected to the insertion section 114. The outer end of the test head body 113 has a clamping section 116. Both the upper and lower ends of the clamping section 116 have extending protrusions 117. The inner end of the clamping section 116 has a first limiting piece 125, and the outer end of the clamping section 116 has a second limiting piece 118. The outer diameters of both the first limiting piece 125 and the second limiting piece 118 are larger than the outer diameter of the clamping section 116. Recessed positioning channels 119 are provided on both the front and rear sides of the test head body 113. The positioning channels 119 penetrate the inner and outer end faces of the test head body 113. Figure 20As shown. When the two clamping members 79 abut against each other under the drive of the pneumatic gripper cylinder 57, the two limiting notches 124 can abut against the first limiting piece 125 together, which can be used to limit the extreme position of the clamping member 79. The two clamping section grooves 80 can cooperate with the clamping section 116 together. The two clamping section limiting grooves 107 can cooperate with the two extending protrusions 117 respectively. The two limiting section grooves 81 can cooperate with the second limiting piece 118 together.

[0060] The distance between the two positioning clamps 83 should be less than the distance between the two positioning channels 119 on the test head body 113. This ensures that when the test head body 113 is placed between the two positioning clamps 83, and the two positioning clamps 83 are located on either side of the positioning channels 119, the two positioning clamps 83 can exert sufficient clamping force on the test head body 113. Furthermore, the positioning channels 119 prevent accidental misalignment between the positioning clamps 83 and the test head body 113, thus maintaining positioning stability. Additionally, when the clamping assembly needs to move the test head, the test head can be easily moved out from the outer ends of the two positioning clamps 83.

[0061] The outer end of the output shaft of the angle adjustment motor 77 should extend out of the angle adjustment motor 77. In this way, the air intake of the pneumatic gripper cylinder 57 can be processed through the output shaft, and it can also be used in conjunction with a position sensor to monitor the rotation angle of the angle adjustment motor 77.

[0062] Both the Z-axis robotic arm 70 and the Y-axis robotic arm 72 can be equipped with a free slide module or a cylinder; the X-axis robotic arm 71 includes an X-axis nut seat 93 mounted on the X-axis support 73, an X-axis lead screw 94 mounted on the X-axis mounting base 74, and an X-axis drive device 95 for driving the X-axis lead screw 94 to rotate. The X-axis drive device 95 can be a geared motor. When the X-axis drive device 95 is started, it drives the X-axis lead screw 94 to rotate. When the X-axis nut seat 93 remains stationary, the rotation of the X-axis lead screw 94 can drive the entire X-axis mounting base 74 to move in the X-axis direction (inner and outer directions).

[0063] Z-axis robotic arm 70, Y-axis robotic arm 72, and X-axis robotic arm 71 are used to adjust the position of the two clamping parts 79 to clamp and move the test head to the interface to be tested. The insertion and removal drive device 75 is used to provide the two clamping parts 79 with the displacement required to complete the insertion and removal operation. It can be a cylinder.

[0064] The laptop to be tested is placed on the loading and conveying assembly for transport, and then transferred to the testing station by the transfer assembly. At this time, the laptop screen should be in the open state. Then, the centering drive assembly drives the two centering groups to move towards each other until the two centering reference frames 59 contact the two sides of the laptop to be tested, thus achieving the centering process of the laptop to be tested. Next, the testing operation is performed. In the zero position, the two clamping parts 79 should be in the open state under the action of the pneumatic gripper cylinder 57. The Z-axis robotic arm 70, Y-axis robotic arm 72, and X-axis robotic arm 71 adjust the two clamping parts 79 to be located on both sides of the clamping section 3, and then the pneumatic gripper cylinder 57 gradually tightens the two clamping parts 79. When tightened to the limit position, the clamping section grooves 80 of the two clamping parts 79 can jointly form a clamping channel that wraps around the clamping section 3, and the limiting section grooves 81 of the two clamping parts 79 can jointly form a second limiting piece anti-disengagement groove that can cooperate with the second limiting piece 118. Specifically, the two clamping members 79 can only move towards each other to a specific position and stably clamp the clamping section 116 when the clamping section limiting groove 107 is aligned with the extending protrusion 117. This prevents damage to the reference position for adjusting the angle of the test head body 113. Since the groove depth of the limiting section groove 81 is greater than the groove depth of the clamping section groove 80, when the second limiting piece 118 is located in the limiting section groove 81, it can be limited within the limiting section groove 81. This prevents the test head body 113 from accidentally detaching from the two clamping members 79. When the test head moves to the interface to be tested on the laptop computer, the plugging and unplugging operation between the test head and the interface to be tested is realized by the plugging and unplugging drive device 75.

[0065] In practice, laptops are not always placed perfectly horizontally on the testing station; a slight tilt is unavoidable. Therefore, this embodiment incorporates an image acquisition unit 78 and an angle adjustment motor 77. First, the image acquisition unit 78 captures the position of the interface to be tested. Then, the angle adjustment motor 77 adjusts the angle of the test head body 113 to match the angle of the interface. Finally, through the coordinated operation of the Z-axis robotic arm 70, Y-axis robotic arm 72, X-axis robotic arm 71, and the insertion / removal drive device 75, the insertion and removal operation of the test head can be completed. The image acquisition unit 42 can be a camera or a supplementary light.

[0066] After the test is completed, the laptop screen is closed to the system by the closing component, and then the laptop under test is transferred to the unloading conveyor component by the transfer component to enter the next process.

[0067] To further improve work efficiency, two sets of plug-in units can be installed on the support platform 50, such as... Figure 1 and Figure 2 As shown.

[0068] Preferably, the centering assembly further includes a centering sliding frame 58, and the centering reference frame 59 is mounted on the centering sliding frame 58; the test head positioning frame 60 includes a positioning connecting plate 61 connected to the centering reference frame 59, a positioning head 82 is provided at the top of the positioning connecting plate 61, and the positioning clamping rod 83 is provided at the front and rear ends of the outer side of the positioning head 82.

[0069] The positioning head 82 has positioning connection notches 84 at both its front and rear ends;

[0070] The top of the positioning connecting plate 61 is provided with a positioning connecting protrusion 85 that cooperates with the positioning connecting notch 84.

[0071] In this embodiment, the positioning head 82 and the positioning connecting plate 61 can be quickly connected by the snap-fit ​​engagement of the positioning connection notch 84 and the positioning connection protrusion 85. Furthermore, to improve the stability of the connection between the positioning head 82 and the positioning connecting plate 61, a screw can be passed through the positioning head 82 and connected to the positioning connecting plate 61 to further lock the connection.

[0072] To achieve a stable connection between the positioning connecting plate 61 and the centering reference frame 59, a guide groove 121 is provided on the inner end of the positioning connecting plate 61, and a guide protrusion 122 that mates with the guide groove 121 is provided on the outer end of the centering reference frame 59. The engagement of the guide groove 121 and the guide protrusion 122 allows for quick locking of the connection position and facilitates adjustment of the front-to-back position of the test head positioning frame 60 relative to the centering reference frame 59. A locking clearance slot 123 is also provided on the outer end of the positioning connecting plate 61, which can be used for screw through-hole connection.

[0073] Preferably, the centering support frame 108 is on the support platform 50;

[0074] The centering drive assembly includes a centering drive wheel 62 rotatably mounted on the centering support frame 108 and a centering driven wheel 63 spaced apart from the centering drive wheel 62; the centering drive assembly also includes a centering drive device 67 for driving the centering drive wheel 62 to rotate.

[0075] The centering drive assembly also includes a centering linkage belt 64 sleeved on the centering drive pulley 62 and the centering driven pulley 63. The centering linkage belt 64 is divided by the centering drive pulley 62 and the centering driven pulley 63 into a centering belt top section 65 and a centering belt bottom section 66 that are connected to each other.

[0076] Any one of the two pairs of centering sliding frames 58 is connected to the top section 65 of the centering belt, and the other pair of centering sliding frames 58 is connected to the bottom section 66 of the centering belt.

[0077] In this embodiment, the centering drive device 67 is a geared motor. When the laptop to be tested is located at the test station, activating the centering drive device 67 drives the centering drive wheel 62 to rotate, thereby driving the centering connecting belt 64 to transmit power. This, in turn, drives the two centering sliding frames 58, which are respectively connected to the top section 65 and the bottom section 66 of the centering belt, to move towards each other until the inner ends of the two centering reference frames 59 are in contact with both ends of the laptop, thus completing the centering operation. At this time, the laptop is in the set position area, facilitating the movement of the fixture assembly with a uniform displacement.

[0078] The support platform 50 is equipped with a centering limit frame 109, and the centering limit frame 109 is equipped with a centering limit slide rail 110. The centering slide frame 58 is equipped with a centering limit slider 111 that can slide and cooperate with the centering limit slide rail 110.

[0079] In this embodiment, the stability of the two centering sliding frames 58 during sliding can be improved by the cooperation between the centering limit slider 111 and the centering limit slide rail 110.

[0080] Preferably, the outer end of the X-axis connecting seat 76 has a buffer connecting section 86, on which a pressure sensor 87 is installed;

[0081] It also includes a buffer rod 88, the inner end of which passes through the pressure sensor 87 and the buffer connecting section 86 in sequence, and a buffer anti-detachment head 89 is provided on the inner end of the buffer rod 88. The outer end of the buffer rod 88 is connected to the output end of the insertion and removal drive device 75. A buffer elastic element 90 is also sleeved on the buffer rod 88, and the two ends of the buffer elastic element 90 abut against the pressure sensor 87 and the inner end of the buffer rod 88 respectively, so that the outer end face of the buffer anti-detachment head 89 abuts against the inner end face of the buffer connecting section 86.

[0082] In practical plug-in / plug-out operations, there may be slight errors in the distance between each laptop computer to be tested and the fixture. To address this, this embodiment incorporates a buffer rod 88 with a buffer elastic element 90, combined with monitoring by a pressure sensor 87. Specifically, when the plug-in / plug-out drive 75 causes excessive movement of the X-axis connector 76, the X-axis connector 76 moves outward relative to the buffer rod 88. This causes the buffer connecting section 86 to compress the buffer elastic element 90, and the pressure value collected by the pressure sensor 87 will be greater than the set value. This feedback is then sent to the control system, allowing the plug-in / plug-out drive 75 to retract appropriately. Conversely, when the pressure value collected by the pressure sensor 87 is less than the set value, it indicates that the displacement of the X-axis connector 76 has not reached the set state, and this feedback is sent to the control system, allowing the plug-in / plug-out drive 75 to extend appropriately. Furthermore, since the X-axis connector 76 and the buffer connecting section 86 can slide relative to the buffer rod 88, damage to the test interface and test head during excessive movement can be reduced.

[0083] The X-axis mounting base 74 is provided with an inner limiting member 91 that can act on the inner end of the X-axis connecting base 76 and an outer limiting member 92 that can act on the outer end of the X-axis connecting base 76.

[0084] In this embodiment, when the insertion / removal drive device 75 drives the two clamping members 79 to insert or remove, that is, to move inward or outward, the inner limiting member 91 and the outer limiting member 92 can limit the extreme position of the displacement to avoid excessive movement causing ineffective loss of electrical energy and time.

[0085] The X-axis support base 73 is provided with an X-axis support slider 96, and the X-axis mounting base 74 is provided with an X-axis support guide rail 97 that can slide and cooperate with the X-axis support slider 96.

[0086] The X-axis mounting base 74 is provided with an X-axis mounting slider 98, and the X-axis connecting base 76 is provided with an X-axis mounting guide rail 99 that can cooperate with the X-axis mounting slider 98.

[0087] In this embodiment, the stability of the movement of the X-axis mounting base 74 can be improved by the cooperation between the X-axis support slider 96 and the X-axis support guide rail 97, and the stability of the movement of the X-axis connecting base 76 can be improved by the cooperation between the X-axis mounting guide rail 99 and the X-axis mounting slider 98. In this way, the stability of the cooperation between the two clamping parts 79 and the test head can be improved, thereby improving the stability of the insertion and removal operation.

[0088] Preferably, a closed-cover support frame 100 is installed on the support platform 50;

[0089] The closing assembly includes a closing rotation drive device 101 mounted on a closing support frame 100. The output end of the closing rotation drive device 101 is connected to a closing mounting frame 102. A closing extension drive device 106 is mounted on the closing mounting frame 102. A closing connecting frame 103 located above the closing extension drive device 106 is rotatably connected to the closing mounting frame 102. A closing rod 104 is connected to the inner end of the closing connecting frame 103. A closing connecting ear 105 is provided at the bottom end of the closing connecting frame 103.

[0090] The closing assembly also includes a closing connector 133, the two ends of which are hinged to the closing connector ear 105 and the output end of the closing extension and retraction drive device 106, respectively.

[0091] In this embodiment, the lid-closing rotation drive device 101 is a rotary cylinder, and the lid-closing extension drive device 106 is a cylinder.

[0092] When the transfer component moves the laptop from the loading and conveying component to the testing station, the closing cover extension and retraction drive device 106 first extends the retractable end, causing the closing cover connector 133 to tend to move upward. Through the hinge relationship between the closing cover connector 133 and the closing cover connecting ear 105, the closing cover connecting frame 103 can be rotated, thereby rotating the closing cover rod 104 to close it on one side of the closing cover mounting frame 102. After the laptop completes the test, the closing cover extension and retraction drive device 106 resets the closing cover rod 104 to rotate it so that it is horizontally positioned in front of the display end. Then, the closing cover rotation drive device 101 drives the closing cover mounting frame 102 and the closing cover rod 104 to rotate together. During the rotation, the closing cover rod 104 can gradually drive the display end to rotate to the rear until it closes on the system end.

[0093] Furthermore, the transfer assembly includes a transfer up-and-down drive assembly, the output end of which is connected to a transfer support base 1. The transfer support base 1 is provided with two sets of symmetrically arranged and retractable telescopic structure groups 134. Each telescopic structure group 134 has a placement plate 26 at its telescopic end. The rear end of the placement plate 26 is provided with a fixed limiting plate 27. The telescopic end of the telescopic structure group is also provided with a positioning drive device 28. The output end of the positioning drive device 28 is connected to a movable limiting plate 29 that can slide relative to the placement plate 26 and corresponds to the fixed limiting plate 27. The placement plate 26, the fixed limiting plate 27, and the movable limiting plate 29 of the two sets of telescopic structure groups together form a placement area.

[0094] The transfer up-and-down drive component moves the transfer support 1 upward, and the two sets of telescopic structures can cooperate with the feeding conveyor component to transfer the laptop to the placement area. The transfer up-and-down drive component moves the transfer support 1 downward, and the two sets of telescopic structures can cooperate with the unloading conveyor component to transfer the laptop in the placement area onto the unloading conveyor component.

[0095] In this embodiment, the vertical transfer drive assembly can be a slide module, a cylinder, etc. The positioning drive device 28 is a cylinder.

[0096] Moving the placement plate 26 towards the loading or unloading conveyor assembly constitutes forward movement, while moving it away constitutes backward movement. In application, the loading conveyor assembly transports the laptop to be tested. The transfer drive assembly is activated, causing the transfer support 1 to move upward until it is in communication with the loading conveyor assembly. Then, the telescopic ends of the two sets of telescopic structures extend forward until they engage with the loading conveyor assembly. The positioning drive device 28 is activated, driving the movable limiting plate 29 forward, i.e., moving it away from the fixed limiting plate 27 to expand the placement area. The laptop to be tested is then transferred into the placement area. The positioning drive device 28 then moves the movable limiting plate 29 backward to position the laptop within the placement area. The telescopic ends of the two sets of telescopic structures reset and continue to extend backward, positioning the placement area within the testing station area. The positioning drive device 28 then moves the movable limiting plate 29 forward to appropriately expand the placement area for subsequent centering operations. The centering drive assembly is activated, causing the centering groups on both sides to move towards each other until… After contacting both sides of the laptop, the laptop is in a pre-set centering position. At this point, the positioning drive device 28 can be used to move the movable limiting plate 29 to tighten the placement area and position the laptop to be tested. Then, the adjustment component moves the gripper cylinder 57 to hold the test head, and then moves the test head to the interface to be tested on the laptop for corresponding plugging and unplugging operations. After the test is completed, the telescopic ends of the two sets of telescopic structures are moved forward to reset to the zero position. Then, the transfer support 1 is moved down by the transfer up and down drive component until it is in communication with the unloading conveyor component. Then, the telescopic ends of the two sets of telescopic structures are extended forward until they can cooperate with the unloading conveyor component. The positioning drive device 28 is activated to drive the movable limiting plate 29 to move away from the fixed limiting plate 27 to expand the placement area. The tested laptop can then be transferred to the unloading conveyor component for subsequent operations.

[0097] To enable the two sets of telescopic structures to cooperate with the feeding conveyor and the unloading conveyor, preferably, the feeding conveyor includes a feeding conveyor frame 34, which includes a feeding transfer section 36 and a feeding conveyor section 35 connected to the feeding transfer section 36. The feeding conveyor frame 34 is provided with feeding telescopic clearance openings 37 on both sides of the feeding transfer section 36.

[0098] The unloading conveying assembly includes an unloading conveying frame 38, which includes an unloading transfer section 39 and an unloading conveying section 40 connected to the unloading transfer section 39. The unloading conveying frame 38 is provided with unloading telescopic clearance openings 41 on both sides of the unloading transfer section 39.

[0099] The transfer up-and-down drive assembly enables the transfer support 1 to move upward and connect with the loading conveyor 34, and the two placement plates 28 can be respectively placed into the two loading telescopic clearance ports 37. The transfer up-and-down drive assembly enables the transfer support 1 to move downward and connect with the unloading conveyor 38, and the two placement plates 28 can be respectively placed into the two unloading telescopic clearance ports 41.

[0100] In this embodiment, the loading conveyor section 35 is used to transport the laptop computer to be tested to the loading transfer section 36; the unloading conveyor section 40 is used to receive the tested laptop computer transported by the unloading transfer section 39 and transfer it to the next process.

[0101] In application, the laptop to be tested is placed on the loading conveyor section 35 for transport. First, the transfer support 1 is moved upward and connected to the loading conveyor frame 34 by the transfer up and down drive assembly. The telescopic ends of the two telescopic structure groups are controlled to extend forward and be placed into the two loading telescopic clearance ports 37 respectively. At this time, the placement plate 26 is located at the two loading telescopic clearance ports 37 and is in communication with the loading transfer section 36. Then, the positioning drive device 28 drives the movable limit plate 29 to move away from the fixed limit plate 27. When the laptop to be tested on the loading conveyor section 35 enters the loading transfer section 36, the two placement plates 26 are exactly below the laptop to be tested. Then, the positioning drive device 28 retracts the position of the movable limit plate 29 so that the laptop to be tested can be positioned between the movable limit plate 29 and the fixed limit plate 27. Then, the telescopic ends of the two telescopic structure groups are reset and continue to extend backward, so that the laptop to be tested leaves the loading transfer section 36 and is located on the test station. At this point, the loading conveyor 34 can send the next laptop computer to be tested into the loading transfer section 36 for buffering.

[0102] After the laptop computer completes the test, the telescopic ends of the two telescopic structure groups are first reset forward. Then, the upper and lower drive components are used to move the support base 1 downward to connect with the unloading conveyor 38. The telescopic ends of the two telescopic structure groups are then controlled to extend forward and be placed into the two unloading telescopic clearance ports 41 respectively. At this time, the tested laptop computer is moved to the unloading transfer section 39. Then, the positioning drive device 28 is used to increase the distance between the movable limit plate 29 and the fixed limit plate 27. At this time, the tested laptop computer can be transferred from the unloading transfer section 39 to the unloading transfer section 40 under the transmission of the unloading conveyor 38 for subsequent operations.

[0103] The two telescopic structure groups have a placement plate 26 that can jointly support the laptop. When the laptop is moved through the telescopic structure group, the positioning drive device 28 should drive the movable limiting plate 29 to keep the laptop pressed against the fixed limiting plate 27, so as to prevent the laptop from shaking when it is moved.

[0104] This embodiment employs a layered design for the loading and unloading conveyor systems. When one laptop to be tested is at the testing station, the next laptop can be buffered on the loading transfer section 36, effectively reducing working time and improving production efficiency. Furthermore, the insertion and cooperation of the telescopic structure assembly with the loading telescopic clearance port 37 and the unloading telescopic clearance port 41 facilitates easy transfer of products between the loading, testing, and unloading stations. During the transfer process, the cooperation between the movable limiting plate 29 and the fixed limiting plate 27 helps maintain the stability of the laptop as much as possible.

[0105] To further improve efficiency, loading transfer sections 35 can be provided on both sides of the loading transfer section 36, and correspondingly, unloading transfer sections 40 can be provided on both sides of the unloading transfer section 39. In this way, the loading transfer section 36 can receive laptops to be tested from two directions, and both loading transfer sections 35 can buffer the laptops to be tested; similarly, the unloading transfer section 39 can transport the tested laptops in two directions.

[0106] Preferably, both the loading transfer section 36 and the unloading transfer section 39 include a main transfer drive shaft 52, a secondary transfer drive shaft 43, and a transfer drive belt 44 sleeved on the main transfer drive shaft 52 and the secondary transfer drive shaft 43. Both the loading transfer section 36 and the unloading transfer section 39 also include a transfer drive assembly for driving the main transfer drive shaft 52 to rotate.

[0107] Both the loading conveyor section 35 and the unloading conveyor section 40 include a main conveyor shaft 45, a secondary conveyor shaft 46, and a conveyor belt 47 sleeved on the main conveyor shaft 45 and the secondary conveyor shaft 46. Both the loading conveyor section 35 and the unloading conveyor section 40 also include a conveyor drive assembly for driving the main conveyor shaft 45 to rotate.

[0108] In this embodiment, the main drive shaft 52 and the secondary drive shaft 43 of the loading transfer section 36 are rotatably mounted on the loading transfer section 36; the main drive shaft 45 and the secondary drive shaft 46 of the loading conveying section 35 are rotatably mounted on the loading conveying section 35; the main drive shaft 52 and the secondary drive shaft 43 of the unloading transfer section 39 are rotatably mounted on the unloading transfer section 39; and the main drive shaft 45 and the secondary drive shaft 46 of the unloading conveying section 40 are rotatably mounted on the unloading conveying section 40.

[0109] Both the transfer drive assembly and the transmission drive assembly include a transfer drive device 53 and a transfer driven pulley 55. The output end of the transfer drive device 53 is fitted with a transfer drive pulley 54. Both the transfer drive assembly and the transmission drive assembly also include a transfer drive belt 56 fitted on the transfer drive pulley 54 and the transfer driven pulley 55. The transfer drive device 53 can be a geared motor.

[0110] The driven wheels 55 in the loading transfer section 36 and the unloading transfer section 39 are sleeved on the main transfer drive shaft 52, and the driven wheels 55 in the loading conveying section 35 and the unloading conveying section 40 are sleeved on the main conveying drive shaft 45.

[0111] When the transfer drive device 53 is activated, the transfer drive wheel 54 can be driven to rotate. Through the transmission action of the transfer drive belt 56 and the transfer driven wheel 55, each main drive shaft can be driven to rotate, thereby driving each drive belt to drive, and then driving the laptop to be tested to be transferred on the loading conveyor assembly, and the laptop that has been tested to be transferred on the unloading conveyor assembly.

[0112] Preferably, both the loading conveyor section 35 and the unloading conveyor section 40 include loading and unloading support plates 49 located between the conveyor belts 47.

[0113] In this embodiment, the loading and unloading support plate 49 can be used to support a laptop computer that is to be tested or has already been tested.

[0114] Both the loading conveyor 34 and the unloading conveyor 38 are equipped with several limiting rollers 48 that rotate on both sides of their conveying direction.

[0115] In this embodiment, the setting of the limiting roller 48 can limit the transfer of the laptop under test on the loading conveyor 34, limit the transfer of the laptop under test on the unloading conveyor 38, and reduce the friction between the laptop and the limiting roller frame.

[0116] It is worth noting that when the loading transfer section 36 is equipped with a limit roller 48, after the laptop to be tested enters the placement plate 26, the transfer support 1 needs to be moved up appropriately by the transfer up and down drive device 42. This allows the two sets of telescopic structures to be raised appropriately until the laptop to be tested is higher than the height of the limit roller 48, and then the telescopic ends of the two telescopic structures are reset. Similarly, when the unloading transfer section 39 is equipped with a limit roller 48, the transfer support 1 should be moved down appropriately by the transfer up and down drive device 42 to be higher than the height of the limit roller 48 of the unloading transfer section 39. Then the telescopic ends of the two telescopic structures are extended. When the laptop to be tested is directly above the unloading transfer section 39, the transfer support 1 is moved down by the transfer up and down drive device 42 to connect the placement plate 26 with the unloading transfer section 39 to facilitate the unloading of the laptop to be tested.

[0117] Preferably, the telescopic structure assembly includes a primary telescopic seat 2 slidably mounted on the transfer support seat 1, and a secondary telescopic seat 3 slidably mounted on the primary telescopic seat 2;

[0118] The telescopic structure assembly also includes a primary transmission wheel assembly mounted on the transfer support 1. The primary transmission wheel assembly includes a primary transmission gear 4 and two primary reversing gears 5.

[0119] The two ends of the primary telescopic seat 2 are connected to a primary transmission belt 6 that is sleeved on the primary transmission gear 4 and two primary reversing gears 5.

[0120] A secondary transmission wheel set is provided on the primary telescopic seat 2. The secondary transmission wheel set includes two secondary transmission gears 7 located at both ends of the primary telescopic seat 2 and a secondary transmission belt 8 sleeved on the two secondary transmission gears 7. The secondary transmission belt 8 is divided by the two secondary transmission gears 7 into a secondary belt top section 68 and a secondary belt bottom section 69 that are connected to each other.

[0121] The bottom end of the secondary telescopic seat 3 is fixedly connected to the top section 68 of the belt via the secondary connector 18;

[0122] The telescopic structure assembly also includes a fixed seat 9 connected to the transfer support 1 and located between the two first-stage reversing gears 5, and the fixed seat 9 is fixedly connected to the bottom end section 69 of the belt;

[0123] The transfer support 1 is also equipped with a telescopic drive assembly for driving the first-stage transmission gear 4 to rotate.

[0124] In this embodiment, the primary transmission wheel assembly is connected to the transfer support 1 via a primary connecting frame 33, such as... Figure 34As shown. The two ends of the primary telescopic seat 2 are fixedly connected to the two ends of the primary transmission belt 6 via primary connectors 22. In the primary transmission wheel set, the two primary reversing gears 5 are located above the primary transmission gear 4, and the primary transmission gear 4 is located in the area between the two primary reversing gears 5. The fixed seat 9 is located above the primary transmission gear 4.

[0125] The secondary telescopic seat 3 can be regarded as the telescopic end of the telescopic structure assembly. Accordingly, the placement plate 26 and the positioning drive device 28 are both installed on the top surface of the secondary telescopic seat 3.

[0126] Preferably, the telescopic drive assembly includes a telescopic drive device 10 and a synchronous transmission rod 11;

[0127] The output end of the telescopic drive device 10 is fitted with a drive gear 12;

[0128] The first-stage transmission gears 4 of the two sets of telescopic structures are respectively sleeved on the two ends of the synchronous transmission rod 11, and the synchronous transmission rod 11 is also sleeved with a driven gear 13.

[0129] The telescopic drive assembly also includes a telescopic drive belt 14 sleeved on the drive gear 12 and the drive gear 13.

[0130] In this embodiment, the telescopic drive device 10 can be a geared motor.

[0131] In this embodiment, the initial position of the primary transmission wheel set and the primary transmission belt, the relative position of the secondary connector 18 and the top section 68 of the secondary belt, and the relative position of the fixed seat 9 and the bottom section 69 of the secondary belt can be adjusted according to the actual direction of movement and displacement to achieve the effects of unidirectional forward extension, unidirectional backward extension and bidirectional extension.

[0132] This embodiment is applicable to the insertion and removal testing machine. The telescopic structure group needs to transfer the laptop to the testing station, the loading transfer section, and the unloading transfer section. Therefore, the zero-position configuration of this embodiment is as follows: the primary transmission wheel group is located in the middle area of ​​the primary transmission belt 6, the secondary connector 18 is connected to the middle area of ​​the top section 68 of the secondary belt, and the fixing seat 9 is connected to the middle area of ​​the bottom section 69 of the secondary belt. In this way, the primary telescopic seat 2 and the secondary telescopic seat 3 can extend forward relative to the transfer support seat 1, so that the placement plate 26 can move to the loading transfer section or the unloading transfer section. The primary telescopic seat 2 and the secondary telescopic seat 3 can also extend backward relative to the transfer support seat 1, so that the placement plate 26 is located at the testing station.

[0133] Taking the forward movement of the primary telescopic seat 2 and the secondary telescopic seat 3 driven by the telescopic drive assembly as an example, in application, the telescopic drive device 10 is started. Through the cooperation of the drive gear 12, the driven gear 13, and the telescopic drive belt 14, the synchronous transmission rod 11 can be driven to rotate, which in turn can drive the primary transmission gear 4 in the two sets of primary transmission wheel sets to rotate synchronously. Under the transmission action of the primary transmission gear 4 and the two primary reversing gears 5, the primary transmission belt 6 will drive the primary telescopic seat 2 to move forward relative to the transfer support seat 1 through the primary connector 22, completing the primary extension action. During the forward movement of the primary telescopic seat 2, the secondary transmission belt 8 set on it also tends to move forward. Since the fixed seat 9 fixes and restricts the bottom section 58 of the secondary belt, in order to meet the displacement requirement, under the support of the two secondary transmission gears 7, the top section 57 of the secondary belt will move forward along with the secondary connector 18, which can drive the secondary telescopic seat 3 to move forward relative to the primary telescopic seat 2, thereby completing the secondary extension action. Similarly, the telescopic drive assembly can also drive the first-stage telescopic seat 2 and the second-stage telescopic seat 3 to move backward to complete the corresponding first-stage extension action and second-stage extension action.

[0134] As can be seen, in this embodiment, through the linkage design between the first-level telescopic seat and the second-level telescopic seat, bidirectional long-range telescopic displacement can be achieved in a limited space to meet the distance requirements between the transfer support seat 1 and the loading transfer section 36, the unloading transfer section 39 and the test station.

[0135] Preferably, the placement plate 26 is positioned above the positioning drive device 28 via a support block 51;

[0136] The movable limiting plate 29 has a sliding opening 30 that allows the placement plate 26 to pass through;

[0137] The top of the secondary telescopic seat 3 is provided with a positioning guide rail 31;

[0138] The movable limiting plate 29 is provided with a positioning guide block 32 that can cooperate with the positioning guide rail 31.

[0139] In this embodiment, the sliding groove 30 prevents the movable limiting plate 29 from detaching from the placement plate 26 during movement. The cooperation between the positioning guide rail 31 and the positioning guide block 32 improves the stability of the movement of the movable limiting plate 29.

[0140] To maintain the synchronicity of the extension and retraction of the two primary telescopic seats 2, a synchronizing connecting rod 23 is connected between the primary telescopic seats 2 of the two sets of telescopic structures. This improves the stability of the two telescopic structures when transferring products.

[0141] The top surface of the transfer support 1 is connected to a cable routing frame 25 located between the two sets of telescopic structure groups via several columns 24. The cable routing frame 25 can be used for cable routing and other installations.

[0142] Preferably, a primary guide block 15 is installed on the transfer support 1, and a primary slide groove 16 is formed on the primary guide block 15;

[0143] The primary telescopic seat 2 is connected to a primary guide rail 17 that can slide and engage with the primary slide groove 16;

[0145] The secondary telescopic seat 3 is connected to a secondary guide rail 19 that can slide and engage with the secondary slide groove 21.

[0146] In this embodiment, the stability of the first-level telescopic seat 2 during telescopic movement can be improved by the cooperation between the first-level guide rail 17 and the first-level guide block 15; the stability of the second-level telescopic seat 3 during telescopic movement can be improved by the cooperation between the second-level guide rail 19 and the second-level guide block 20.
