Technical Field

[0001] This invention relates to the field of automatic gold thread testing technology, specifically to an automatic gold thread testing device. Background Technology

[0002] Automatic gold wire bonding inspection equipment is a specialized device used to inspect the quality of gold wire bonding in electronic components (such as chips and integrated circuit packages). Gold wire bonding is a core process in the semiconductor packaging field, connecting chip pins to external package pins through fine gold wires to achieve electrical signal transmission. The core function of this device is to detect defects in the gold wire connections, ensuring the reliability of electronic components.

[0003] In the traditional gold thread testing process, the loading, testing, and unloading stations are often independent of each other, and the pallets need to be moved across areas. This results in gaps in the physical connection of the equipment, which leads to wasted time and coordination breakdowns due to waiting for the equipment to be moved. Therefore, the practicality is low. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic gold thread detection device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic gold thread testing device includes: a feeding device for inputting a pallet containing materials to be tested, a worktable, a conveying device for receiving and conveying the pallet, a testing device, and a discharging device for receiving a pallet containing materials that have been tested. The conveying device is installed on the workbench, the feeding device and the unloading device are installed on the front and rear sides of the conveying channel of the conveying device, and the detection device is installed on the workbench to detect the material on the conveying device.

[0006] In some embodiments, the feeding device includes a feeding lifting module, a feeding box, and a pushing mechanism. The output end of the feeding lifting module is connected to the feeding box, and the pushing mechanism is disposed on the feeding lifting module to push the material in the feeding box into the conveying device.

[0007] In some embodiments, the pushing mechanism includes a pushing drive module and a pushing clamp. The pushing drive module is connected to the loading lifting module, and the output end of the pushing drive module is connected to the pushing clamp to drive the pushing clamp to push out the tray in the loading box.

[0009] In some embodiments, the conveying device includes two track mechanisms and a conveying transverse module. One track mechanism and the conveying transverse module are disposed on the worktable. The output end of the conveying transverse module is connected to the other track mechanism to drive and adjust the distance between the two track mechanisms. The two track mechanisms are arranged opposite to each other to form a conveying channel.

[0010] In some embodiments, the conveying device further includes a rotary driver, the track mechanism includes a rotating frame, a rotating belt and a plurality of rotating rollers, the output end of the rotary driver is connected to two of the rotating belts, each of the rotating belts is wound around a plurality of the rotating rollers on a corresponding side, and each of the rotating rollers is rotatably mounted on the rotating frame on a corresponding side.

[0011] In some embodiments, the conveying channel is equipped with multiple arrival sensors to detect whether the pallet has arrived.

[0012] In some embodiments, a positioning adsorption device is also included, which includes an adsorption longitudinal movement lifting drive mechanism and an adsorption plate. The adsorption longitudinal movement lifting drive mechanism is disposed on the worktable, and the output end of the adsorption longitudinal movement lifting drive mechanism is connected to the adsorption plate. The adsorption plate is movable to form a negative pressure adsorption tray.

[0013] In some embodiments, the adsorption plate is provided with adsorption protrusions, and the adsorption protrusions are provided with adsorption holes to move the adsorption tray.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: By placing the loading device and the unloading device on the front and rear sides of the conveying channel of the conveying device, respectively, the pallet moves continuously along the conveying channel after being pushed out by the loading device. The detection mechanism detects the gold thread on the conveying channel, and the pallet directly enters the unloading device after the detection is completed. The entire process does not require cross-area handling outside the conveying line. This achieves synchronous connection of loading, conveying, detection, and unloading, eliminates spatial and temporal gaps, and improves the practicality of the equipment.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] In the following embodiments, referring to the coordinate system in the accompanying drawings, the direction pointed to by the arrow on the X-axis is right, the direction pointed to by the arrow on the Y-axis is forward, and the direction pointed to by the arrow on the Z-axis is up.

[0021] like Figure 1 and Figure 2 As shown, an automatic gold thread testing device 10 is provided, including: a feeding device 100 for inputting a tray 700 containing materials to be tested, a worktable 200, a conveying device 300 for receiving and conveying the tray 700, a testing device 400, and a discharging device 500 for receiving the tray 700 containing materials that have been tested; the conveying device 300 is disposed on the worktable 200, the feeding device 100 and the discharging device 500 are disposed on the front and rear sides of the conveying channel of the conveying device 300, and the testing device 400 is disposed on the worktable 200 to test the materials on the conveying device 300.

[0022] Specifically, the feeding device 100, acting as the input end, is responsible for orderly feeding the tray 700 containing the material to be tested into the testing process. The unloading device 500, located at the end, receives the tray 700 after testing, forming a closed loop. The workbench 200 provides a stable mounting foundation for the entire conveying device 300 and the testing device 400. The conveying device 300, mounted on the workbench 200, has a conveying channel, with its front and rear ends connected to the feeding device 100 and the unloading device 500, respectively, to undertake the task of transporting the tray 700. The testing mechanism 440, mounted on the workbench, tests the material on the tray 700 as it passes by. All components work together to automate the process from feeding to testing to receiving. Furthermore, in this embodiment, the material to be tested is gold thread.

[0023] It is worth noting that this application positions the loading device 100 and the unloading device 500 on the front and rear sides of the conveying device 300, respectively. After the pallet 700 is pushed out from the loading device 100, it moves continuously along the conveying device 300. The detection mechanism 440 detects the gold wire on the conveying device 300. After the detection is completed, the pallet 700 directly enters the unloading device 500. The entire process does not require leaving the conveying line for cross-area handling. This achieves synchronous connection of loading, conveying, detection, and unloading, eliminating spatial and temporal gaps and improving the practicality of the equipment. Furthermore, the conveying speed of the conveying device 300 can be preset to match the loading and detection speeds, thereby avoiding the problem of multi-device coordination misalignment and realizing the entire process of the conveying device 300 in series, allowing the entire detection process to operate without interruption and with high efficiency.

[0024] To facilitate feeding by the feeding device 100, such as Figures 1 to 3As shown, in some embodiments, the feeding device 100 includes a feeding lifting module 110, a feeding box 120 and a pushing mechanism 130. The output end of the feeding lifting module 110 is connected to the feeding box 120, and the pushing mechanism 130 is disposed on the feeding lifting module 110 to push the material in the feeding box 120 into the conveying device 300.

[0025] Specifically, the feeding device 100 also includes a feeding shell connected to the conveying device 300, i.e., the front of the feeding shell is open. The feeding lifting module 110 includes a feeding lifting slide rail, a feeding lifting slider, and a feeding lifting driver. The feeding lifting slide rail is installed inside the feeding shell through a mounting bracket. The feeding lifting slider is slidably disposed on the feeding lifting slide rail. The feeding lifting driver is disposed on the feeding lifting slide rail, and the output end of the feeding lifting driver is connected to the feeding lifting slider. The feeding box 120 is installed on the feeding lifting slider so that the feeding box 120 slides along the Z-axis on the feeding lifting slide rail. Furthermore, the number of feeding lifting sliders corresponds to the number of feeding boxes 120. Each feeding box 120 is installed on one feeding lifting slider. The number of feeding boxes 120 is set as needed and is not limited here. In this embodiment, two feeding boxes 120 are set. When one feeding box 120 is empty, the feeding lifting driver removes this feeding box 120 and pushes in another feeding box 120 for feeding. The pushing mechanism 130 is installed on the left side of the loading lifting slide rail, and the pushing mechanism 130 is set in correspondence with the conveying channel in the conveying device 300. That is, the pushing position of the pushing mechanism 130 is set in correspondence with the conveying channel so that the pallet 700 can be pushed into the conveying device 300.

[0026] To facilitate the feeding mechanism 130 in feeding, such as Figures 1 to 3 As shown, in some embodiments, the pushing mechanism 130 includes a pushing drive module 131 and a pushing clamp 132. The pushing drive module 131 is connected to the loading lifting module 110, and the output end of the pushing drive module 131 is connected to the pushing clamp 132 to drive the pushing clamp 132 to push out the tray 700 in the loading box 120.

[0027] Specifically, the pushing mechanism 130 also includes a pushing mounting base 133, which is located on the left side of the mounting frame connected to the feeding lifting slide rail, for connection with the feeding lifting module 110. The pushing drive module 131 includes a pushing drive slide rail, a pushing drive slider, and a pushing drive driver. The pushing drive slide rail is mounted on the pushing mounting base 133, the pushing drive slider is slidably mounted on the pushing drive slide rail, and the pushing drive driver is mounted on the pushing drive slide rail. The output end of the pushing drive driver is connected to the pushing drive slider. The pusher clamp 132 is connected to the pusher drive slider via a horizontal plate. The connection of the horizontal plate makes the pusher clamp 132 parallel to the pusher drive slide rail, i.e., both are set along the Y-axis. The pusher clamp 132 is set facing the conveying channel to push the pallet 700 into the conveying device 300. The pusher clamp 132 is set as a clamp that is driven by a cylinder to open and close. The pusher clamp 132 can hold the pallet 700 for pushing, or it can push it directly by pushing force.

[0028] In another embodiment, the push end of the pusher clamp 132 is provided with a buffer protective sleeve, which may be made of rubber, but is not limited to rubber, to avoid damaging the gold wire during the push process.

[0029] To facilitate the use of the feeding device 500, such as Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the unloading device 500 includes an unloading lifting module 510 and an unloading box 520. The output end of the unloading lifting module 510 is connected to the unloading box 520, which is used to receive a tray 700 containing materials that have been inspected.

[0030] Specifically, the unloading device 500 also includes an unloading shell connected to the conveying device 300, i.e., the unloading shell has an open rear side. The unloading lifting module 510 includes an unloading lifting slide rail, an unloading lifting slider, and an unloading lifting driver. The unloading lifting slide rail is installed inside the unloading shell via a mounting bracket. The unloading lifting slider is slidably mounted on the unloading lifting slide rail. The unloading lifting driver is mounted on the unloading lifting slide rail, and the output end of the unloading lifting driver is connected to the unloading lifting slider. The feeding box 520 is installed on the feeding lifting slider so that the feeding box 520 slides along the Z-axis on the feeding lifting slide rail; and the number of feeding boxes 520 is set in correspondence with the number of feeding lifting sliders. Each feeding box 520 is installed on a feeding lifting slider. The number of feeding boxes 520 is set as needed and is not limited here. In this embodiment, two feeding boxes 520 are set. When the feeding box 520 at the feeding position is full, the feeding lifting driver removes the feeding box 520 and pushes another feeding box 520 to the feeding position to receive the material.

[0031] To facilitate the use of the conveying device 300, such as Figure 2 and Figure 5As shown, in some embodiments, the conveying device 300 includes two track mechanisms 310 and a conveying transverse module 320. One track mechanism 310 and the conveying transverse module 320 are disposed on the worktable 200. The output end of the conveying transverse module 320 is connected to the other track mechanism 310 to drive and adjust the distance between the two track mechanisms 310. The two track mechanisms 310 are arranged opposite to each other to form a conveying channel.

[0032] Specifically, the left track mechanism 310 and the right track mechanism 310 form a conveying channel along the Y-axis, and the conveying transverse module 320 is configured in two units, front and rear, to drive the right track mechanism 310 to slide along the X-axis, thereby adjusting the distance between the left track mechanism 310 and the right track mechanism 310. The conveying transverse module 320 includes a conveying transverse slide rail, a conveying transverse slide plate, and a conveying transverse driver. The conveying transverse slide rail is installed on the right side of the worktable 200, the conveying transverse slide plate is slidably mounted on the conveying transverse slide rail, the conveying transverse driver is mounted on the conveying transverse slide rail, and the output end of the conveying transverse driver is connected to the conveying transverse slide plate. The two ends of the right track mechanism 310 are connected to the front and rear conveying transverse slide plates.

[0033] To facilitate further use of the conveying device 300, such as Figure 2 and Figure 5 As shown, in some embodiments, the conveying device 300 further includes a rotary driver 330, and the track mechanism 310 includes a rotating frame 311, a rotating belt 312 and a plurality of rotating rollers 313. The output end of the rotary driver 330 is connected to two rotating belts 312. Each rotating belt 312 is wound around a plurality of rotating rollers 313 on the corresponding side, and each rotating roller 313 is rotatably mounted on the rotating frame 311 on the corresponding side.

[0034] Specifically, the left rotating frame 311 is installed on the left side of the workbench 200, and the two ends of the right rotating frame 311 are connected to the front and rear conveyor transverse slides. The left rotating frame 311 is higher overall to compensate for the height supplied by the conveyor transverse module 320 to the right rotating frame 311, so that the top surface of the right rotating frame 311 is flush with the top surface of the left rotating frame 311. Multiple rotating rollers 313 on the rotating frame 311 are arranged in a ring, and each rotating roller 313 is rotatably mounted on the corresponding rotating frame 311 via a connecting rod. A rotating belt 312 is sleeved on the multiple rotating rollers 313 on the corresponding side, and the top ends of two rotating belts 312 are at the same height to allow the pallet 700 to be placed flat. A rotary actuator 330 is mounted on the left side of the left rotating frame 311. Rotating holes are provided on both rotating frames 311. A rotating rod is connected to the output end of the rotary actuator 330. The rotating rod is rotatably positioned within the two rotating holes, and its length is greater than the maximum opening distance between the two rotating frames 311. The rotary actuator 330 drives two rotating belts 312 to rotate via the rotating rod, thereby driving the corresponding rotating rollers 313 to rotate, horizontally conveying the tray 700 along the Y-axis. The arrangement of the rotating rod being rotatably positioned within the two rotating holes and the right rotating frame 311 being movable along the X-axis is known to those skilled in the art and is existing technology that can be implemented; therefore, it will not be described in detail here.

[0035] It is worth mentioning that multiple rotating belts 312 on each side can be configured to form a progressive transmission method. The progressive transmission method using multiple rotating belts 312 is a technique known to those skilled in the art and is achievable, and will not be described in detail in this embodiment. That is, when the rotating driver 330 is driven, the front rotating belt 312 drives the front rotating roller 313 to rotate, and the front rotating roller 313 drives the rear rotating belt 312 sleeved above it to rotate, thereby causing the rear rotating roller 313 to rotate. This progressive transmission is achieved step by step, forming a multi-layered progressive transmission.

[0036] To increase the usability of the equipment, such as Figure 5 As shown, in some embodiments, the conveying device 300 is provided with a plurality of arrival sensors 340 on the conveying channel to detect whether the pallet 700 has arrived.

[0037] Specifically, the arrival sensor 340 can be configured as an infrared sensor to detect the arrival of materials. Multiple arrival sensors 340 can be used, and this is not limited. In this embodiment, four arrival sensors 340 are configured, one at each of the front and rear ends of the right rotating frame 311, to detect whether the tray 700 has arrived at or left the conveying channel; see reference. Figure 2 and Figure 7A position sensor 340 can be installed at the height measuring mechanism 430, and another can be installed at the detection mechanism 440, in order to monitor the movement of materials at any time and prevent missed detection.

[0038] To facilitate the use of the positioning adsorption device 600, such as Figure 2 and Figure 6 As shown, in some embodiments, the gold thread automatic detection equipment 10 further includes a positioning adsorption device 600, which includes an adsorption longitudinal movement lifting drive mechanism 610 and an adsorption plate 620. The adsorption longitudinal movement lifting drive mechanism 610 is disposed on the workbench 200, and the output end of the adsorption longitudinal movement lifting drive mechanism 610 is connected to the adsorption plate 620. The adsorption plate 620 moves to form a negative pressure adsorption tray 700.

[0039] Specifically, the adsorption longitudinal movement lifting drive mechanism 610 includes an adsorption longitudinal movement module 611 and an adsorption lifting module 612. The adsorption longitudinal movement module 611 includes an adsorption longitudinal movement slide rail, an adsorption longitudinal movement slide plate, and an adsorption longitudinal movement driver. The adsorption longitudinal movement slide rail is mounted on the worktable 200 and is located between the left and right rotating frames 311. The adsorption longitudinal movement slide plate is slidably mounted on the adsorption longitudinal movement slide rail, and the adsorption longitudinal movement driver is mounted on the adsorption longitudinal movement slide rail. The output end of the adsorption longitudinal movement driver is connected to the adsorption longitudinal movement slide plate. The adsorption lifting module 612 may be, but is not limited to, an adsorption lifting driver. The adsorption lifting driver may be, but is not limited to, a cylinder. The adsorption lifting driver is mounted on the adsorption longitudinal movement slide plate via a connecting plate so as to move the adsorption plate 620 in the Y-axis direction. The output end of the adsorption lifting driver is connected to the adsorption plate 620 via a mounting plate so as to drive the adsorption plate 620 in the Z-axis direction.

[0040] To facilitate the operation of the adsorption plate 620, such as Figure 6 As shown, in some embodiments, the adsorption plate 620 is provided with adsorption protrusions, and the adsorption protrusions are provided with adsorption holes to move the adsorption tray 700.

[0041] Specifically, the adsorption protrusions are regularly arranged on the surface of the adsorption plate 620, such as in a matrix distribution. The height of the adsorption protrusions is slightly higher than the reference surface of the adsorption plate 620 to form precise contact with the bottom of the tray 700. Each adsorption protrusion has a through-hole, which is usually connected to the air passage. The vacuum negative pressure system generates negative pressure through the adsorption holes, thereby firmly adsorbing the tray 700 onto the adsorption protrusions and ensuring that the tray 700 will not shift or shake during movement or positioning.

[0042] To facilitate the detection of gold threads, such as Figure 7As shown, in some embodiments, the detection device 400 includes a barcode scanning mechanism 410, a marking mechanism 420, a height measuring mechanism 430, and a detection mechanism 440, and the barcode scanning mechanism 410, the marking mechanism 420, the height measuring mechanism 430, and the detection mechanism 440 are sequentially connected to the worktable 200 along the conveying direction of the conveying device 300.

[0043] Specifically, the detection device 400 also includes a detection transverse module 450 and a detection lifting module 460. The output end of the detection transverse module 450 is connected to the detection lifting module 460, and the output end of the detection lifting module 460 is connected to the height measuring mechanism 430, the marking mechanism 420, and the detection mechanism 440. The detection transverse module 450 and the detection lifting module 460 are used to synchronously drive the height measuring mechanism 430, the marking mechanism 420, and the detection mechanism 440 to adjust their positions so that the height measuring mechanism 430, the marking mechanism 420, and the detection mechanism 440 can accurately reach directly above the material to be detected. The detection transverse module 450 drives the three mechanisms to move along the X-axis, and the detection lifting module 460 drives the three mechanisms to move along the Z-axis. The scanning mechanism 410 is used to read material identification information and can quickly identify barcodes, QR codes, etc. on the materials to input information such as material model and batch into the system, providing a basis for subsequent detection data association and traceability. The scanning mechanism 410 includes a scanning mounting base and a scanner. The scanning mounting base is set on the workbench 200 and is located behind the height measuring mechanism 430. The scanner is mounted on the scanning mounting base. The scanner can be, but is not limited to, laser or image-based. The height measuring mechanism 430 is used to measure the height of the materials. The marking mechanism 420 is used to mark defective products. The detection mechanism 440 accurately detects the core parameters of the materials, verifies marked defective products as needed, and has the function of storing defective images, defective information, defective product location, etc., which can be used for subsequent defect traceability of production time, product position on pallet 700, and defect type. The conveying direction of pallet 700 is set along the Y-axis, that is, the scanning mechanism 410, height measuring mechanism 430, marking mechanism 420, and detection mechanism 440 are arranged in sequence from back to front.

[0044] To facilitate the installation of the testing agency 440, such as Figure 7 As shown, in some embodiments, the detection mechanism 440 includes a detection mounting base and a detection camera (not shown in the figure), the output end of the detection lifting module 460 is connected to the detection mounting base, and the detection camera is mounted on the detection mounting base.

[0045] Specifically, the inspection mounting base is used to position and install the inspection camera. The inspection camera is installed inside the mounting base and acquires images of the chip's gold wires through a high-resolution optical lens. The system then analyzes and processes the images using advanced image processing algorithms. These algorithms can identify features such as the shape, position, and size of the gold wires and compare them with preset standard images or parameters to detect defects. It can detect problems such as excessively large gold wires, bent gold wires, gold wire adhesion, missing gold wires, misaligned gold balls, tail lines, missing resistors, damaged driver chips, ink spots on the chip, missing capacitors, missing EEPROMs, chip contamination, missed gold wires, flying wires, gold wire bridging, and collapsed wires. Furthermore, this inspection camera is a 10,000-pixel full-color industrial camera capable of performing the above-mentioned inspection items in the prior art.

[0046] Furthermore, the detection mounting base is configured as a side-mounted concave shape to embed the detection camera inside the concave shape.

[0047] Specifically, the opening of the concave portion faces rearward, and a detection port is provided at the bottom of the detection mounting base. The detection end of the detection camera detects the material through the detection port. The size and shape of the detection port are set as needed to ensure that the material can be detected. The detection camera is installed in the concave portion of the detection mounting base, which facilitates the installation and positioning of the detection camera and also protects the detection camera.

[0048] To facilitate the use of the marking mechanism 420, such as Figure 7 As shown, in some embodiments, the marking mechanism 420 includes a marking lift driver and a marking pen, the marking lift driver being connected to the detection mounting base, and the output of the marking lift driver being connected to the marking pen.

[0049] Specifically, the marking lift driver is installed on the left side of the detection mounting base. The marking lift driver can be, but is not limited to, a cylinder, to drive the marking pen to approach and mark defective products. The marking pen uses inkjet or laser for instant marking. The method by which the marking lift driver drives the marking pen to move up and down, and the method by which the marking pen marks defective products, are known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.

[0050] In another embodiment, the marker lift driver is directly connected to the output of the detection lift module 460, and is not connected to the detection mounting base.

[0051] To facilitate the installation and use of the lifting drive, such as Figure 7 As shown, in some embodiments, the marking mechanism 420 includes a marking mounting plate, which is detachably connected to the marking lifting driver and the detection mounting base, and the marking mounting plate is used to connect the marking lifting driver to the detection mounting base.

[0052] Specifically, the marking mounting plate is connected to the marking lifting driver and the detection mounting base by threads. That is, one side of the marking mounting plate is connected to the detection mounting plate by threads, and the other side is fixed to the marking lifting driver by threads.

[0053] To facilitate the use of the marking pen, in some embodiments, the marking mounting plate is provided with a bend to avoid obstructing the detection camera.

[0054] Specifically, the front end of the marking mounting plate is bent to the left, and the lifting drive is connected to the left rear end of the marking mounting plate, so that the marking lifting drive and marking pen are further away from the detection camera, which can greatly avoid the marking mechanism 420 from colliding with the detection camera during operation, thereby extending the service life of the device.

[0055] The specific settings for avoiding bends are subject to actual production conditions and are not specified here.

[0056] In another embodiment, the rear end of the marking mounting plate is bent to the right. The lifting driver is connected to the left side of the rear end of the marking mounting plate. This ensures a certain degree of obstacle avoidance while keeping the marking pen closer to the detection component, facilitating the detection process.

[0057] To facilitate height measurement processing, such as Figure 7 As shown, in some embodiments, the height measuring mechanism 430 is configured as a height measuring instrument, which is mounted on the detection mounting base.

[0058] Specifically, the height gauge is positioned at the rear end of the concave portion of the mounting base and behind the marking pen to measure the height of the scanned product. A height gauge is an instrument for accurately measuring the height, thickness, and other dimensions of objects. Common types include laser and optical gauges, featuring high precision and fast response to ensure product dimensional compliance.

[0059] To facilitate testing the use of the transverse module 450, such as Figure 7 As shown, in some embodiments, the detection lateral movement module 450 includes a detection lateral movement slide rail, a detection lateral movement slide plate, and a detection lateral movement driver. The detection lateral movement slide plate is slidably disposed on the detection lateral movement slide rail, the detection lateral movement driver is disposed on the detection lateral movement slide rail, the output end of the detection lateral movement driver is connected to the detection lateral movement slide plate, and the detection lifting module 460 is connected to the detection lateral movement slide plate.

[0060] Specifically, the detection transverse slide is mounted on the workbench 200 via a frame. The detection transverse slide rail serves as the basic load-bearing structure, providing stable horizontal guidance for the entire module. The front side of the detection transverse slide plate is slidably mounted on the detection transverse slide rail, allowing it to move smoothly along the length of the rail, i.e., the X-axis direction. Its rear side is used to connect to the detection lifting module 460. The detection transverse drive can be, but is not limited to, a servo motor or a pneumatic drive. The detection transverse drive is fixed to the detection transverse slide rail, and its power output end is directly connected to the detection transverse slide plate, enabling precise control of the sliding distance and speed of the detection transverse slide plate. By driving the detection transverse slide plate to slide along the detection transverse slide rail through the detection transverse drive, the connected detection lifting module 460 and detection components can achieve precise displacement in the X-axis direction, thereby adapting to the detection position requirements of materials of different specifications and ensuring that the detection components can be accurately aligned with the area to be detected.

[0061] To facilitate testing the use of the lifting module 460, such as Figure 7 As shown, in some embodiments, the detection lifting module 460 includes a detection lifting slide rail, a detection lifting slide plate, and a detection lifting driver. The detection lifting slide rail is connected to the detection transverse slide plate, the detection lifting slide plate is slidably disposed on the detection lifting slide rail, the detection lifting driver is disposed on the detection lifting slide rail, and the output end of the detection lifting driver is connected to the detection lifting slide plate. The height measuring mechanism 430, the marking mechanism 420, and the detection mechanism 440 are connected to the detection lifting slide plate.

[0063] To increase the usability of the equipment, such as Figure 1 and Figure 2As shown, in some embodiments, the workbench 200, conveying device 300, detection device 400, and positioning adsorption device 600 are all encased in a housing to cover the entire workbench 200, conveying device 300, detection device 400, and positioning adsorption device 600. The housing is equipped with an FFU fan filter assembly and a cooling fan. The FFU fan filter assembly is located at the top of the housing to drive airflow and perform high-efficiency filtration to remove particulate contaminants from the air, while maintaining the air pressure and airflow organization in the detection area to prevent dust from affecting the detection effect. The cooling fan is located on the lower side of the housing to reduce the heat inside the equipment through airflow exchange, preventing damage to electronic components due to high temperatures.

[0064] Working principle of the gold thread automatic detection equipment 10: Feeding: Reference Figure 2 and Figure 3 The loading and lifting module 110 drives the two loading boxes 120 to rise and fall until one loading box 120 is raised to the pushing position. The pushing drive module 131 located at the pushing position can drive the pushing clamp 132 to move forward, thereby pushing the tray 700 with gold wire in the loading box to the conveying channel.

[0065] Test: Reference Figure 2 and Figure 5 After the sensor at the rear end of the conveyor channel detects the presence of material, the rotary driver 330 drives the rotating rod to rotate, thereby rotating the rotating belts 312 on both sides. The rotating belts 312 on both sides, in turn, rotate the corresponding rotating rollers 313, thus transporting the pallet 700 from back to front. During transport, the right-side rotating frame 311 can adjust the distance between the two rotating frames 311 through the driving action of the conveyor transverse driver to accommodate pallets 700 of different sizes. When the pallet 700 is transported to the scanning area by the conveyor channel, refer to... Figure 7 The barcode scanner of the barcode scanning mechanism 410 scans the gold wires in the tray 700, recording information such as material model and batch number into the system. After scanning, the sensor detects whether the tray 700 is in position. Once in position, the detection lateral movement module 450 and the detection lifting module 460 drive the height measuring mechanism 430, marking mechanism 420, and detection mechanism 440 to the required detection position. The height measuring mechanism 430 measures the height of the gold wires on the tray 700. After the height measurement, if a defective product is found, the marking lifting driver in the marking mechanism 420 drives the marking pen to descend and mark the gold wire. The tray 700 continues to be conveyed until it reaches below the detection mechanism 440. At this point, the reference... Figure 6The adsorption longitudinal lifting drive mechanism 610 drives the adsorption plate 620 to adsorb the tray 700, thereby positioning and adsorbing the tray 700 to avoid displacement during the detection process and ensure the detection effect of the detection camera inside the detection mechanism 440. After the detection is completed, the positioning sensor 340 at the rear of the detection mechanism 440 and the front of the conveying device 300 senses it.

[0066] Material cutting: Reference Figure 2 and Figure 4 The unloading lifting module 510 drives the unloading box 520 to the unloading position, which is flush with the conveying channel. The inspected pallet 700 is directly transported into the unloading box 520 by the conveying channel without additional drive.

[0067] In addition, this equipment is also equipped with conventional components such as rollers, support legs, computer, digital display pressure gauge, micro differential pressure gauge, three-color indicator light, and pneumatic triple unit. The installation and specific operation of these components are technologies that are known to those skilled in the art and are feasible, and will not be described in detail here.

[0068] Furthermore, in the above embodiments, each driver can be configured as a motor or a cylinder. The sliding of the motor-driven component, the sliding of the cylinder-driven component, and the opening and closing of the pneumatic clamp are techniques known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.

[0069] It is also understood that the automatic gold wire testing equipment 10 of this application can not only cover the testing of gold wires, but also the testing of copper wires, aluminum wires, palladium-plated copper wires, etc.

[0070] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0071] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0072] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0073] In this invention, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0074] Although the description of the invention has been given in conjunction with the specific embodiments described above, it will be apparent to those skilled in the art that many substitutions, modifications, and variations can be made based on the foregoing. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
