Abstract
Description
Technical Field
[0001] This application relates to the field of material conveying, and in particular to a chip bracket inspection and receiving device. Background Technology
[0002] Semiconductor chip supports are essential components used to fix, support, and protect semiconductor chips. They are typically made of engineering plastics, metals, or ceramics, possessing high strength, rigidity, and high-temperature resistance. Supports are indispensable for semiconductor chips, effectively reducing thermal stress, lowering the chip's damage rate, and extending its lifespan.
[0003] Furthermore, semiconductor chip supports also serve to protect the chips. During chip production and storage, supports prevent damage and wear to the chip surface. At the same time, supports also protect the chips from mechanical shocks and vibrations during use, thus ensuring efficient and stable operation. Therefore, supports are of great importance in chip manufacturing and application.
[0004] Currently, the overall efficiency of chip bracket production needs to be improved, especially since chip brackets need to be transferred to another line for testing after being received, which takes a lot of time and affects the overall production efficiency of chip brackets.
[0005] Therefore, how to improve the overall production efficiency of chip scaffolds and construct a new chip scaffold testing and receiving equipment with significantly improved efficiency is the problem that this application needs to solve. Summary of the Invention
[0006] The main purpose of this application is to propose a chip scaffold inspection and receiving device, which aims to solve the problem of low overall production efficiency of current chip scaffolds.
[0007] To address the aforementioned issues, this application proposes a chip carrier inspection and receiving device, comprising a chip carrier inspection unit and a chip carrier receiving unit. The chip carrier testing device includes a conveyor line for conveying the chip carrier and testing mechanisms located above and below the chip carrier conveying path for testing the upper and lower surfaces of the chip carrier, respectively. The chip carrier receiving device includes: A stacking mechanism is used to convey chip carriers from conveyor line one to the unloading position and to cause the chip carriers located at the unloading position and the protective paper above them to fall, wherein the unloading position includes a qualified product unloading position and a non-qualified product unloading position; The paper pick-up and drop-down mechanism is used to pick up protective paper and place it on the stacking mechanism directly above the chip carrier at the unloading position; The paper storage mechanism is used to supply paper to the paper pick-and-place mechanism; The unloading mechanism, located below the stacking mechanism, is used to receive the chip carrier and protective paper from the stacking mechanism and send the chip carrier and protective paper away.
[0008] In one embodiment, the stacking mechanism includes: A pair of parallel, spaced-apart conveyor tracks are provided, and a conveyor space is defined between the pair of conveyor tracks.

[0010] In one embodiment, the first conveyor shaft is also slidably connected to the inner track plate, and the first push-pull device is connected to the first conveyor shaft. The first push-pull device drives the first conveyor shaft to move, causing the chip holder to fall. The first conveying track also includes an upper loading plate for carrying protective paper. The upper loading plate is connected to a push-pull device. The push-pull device moves the upper loading plate, causing the protective paper to fall.
[0011] In one embodiment, the first conveyor shaft is also slidably connected to the inner track plate, and there are two push-pull devices, which are respectively connected to the first conveyor shaft at the qualified product unloading position and the unqualified product unloading position; or There are two inner track plates, located at the qualified product unloading position and the unqualified product unloading position respectively.

[0012] In one embodiment, the stacking mechanism further includes a front baffle mechanism and a rear baffle mechanism disposed in a conveying space and arranged sequentially along the chip carrier conveying direction, the front baffle mechanism and the rear baffle mechanism being located on both sides of the unloading position.
[0013] In one embodiment, the paper loading and unloading mechanism includes: The second rotating device has its output shaft rotatably connected to the first mounting bracket via a swing arm.

[0021] This disclosure proposes a chip scaffold inspection and receiving device, such as... Figure 1As shown, the chip carrier inspection and receiving equipment includes a chip carrier inspection device 1 and a chip carrier receiving device 2. The chip carrier inspection device 1 is used to inspect the chip carriers 3 to identify qualified and unqualified chip carriers 3. The chip carrier receiving device 2 is used to place protective paper 3 under qualified and unqualified chip carriers 3 respectively before receiving them. It should be noted that the mark 3 in each figure represents chip carrier / protective paper.
[0022] Because the accuracy of the chip carrier testing device 1 is not 100%, there is a theoretical probability of missed or false detections. Therefore, all unqualified chip carriers 3 are also padded with protective paper 3, and subsequently manually re-inspected to ensure that no qualified chip carriers 3 are falsely detected. However, since the chip carriers 3 have been tested before being unloaded, and qualified and unqualified chip carriers 3 are separated during unloading, the subsequent manual re-inspection of unqualified chip carriers 3 does not take much time. After all, the proportion of unqualified chip carriers 3 is always extremely small. Therefore, the overall production time of chip carriers is shortened, and the overall production efficiency of chip carriers is improved.
[0023] Figures 1-11 The arrow in the image indicates the conveying direction of the chip holder 3.
[0024] In this embodiment of the present disclosure, the chip carrier detection device 1 includes a conveyor line 1 for conveying the chip carrier 3 and a detection mechanism 14 disposed above and below the conveying path of the chip carrier 3 to detect the upper and lower surfaces of the chip carrier 3 respectively. The conveyor line 1 includes at least a pair of conveyor tracks 13.
[0025] The second transport track 13 can be constructed using the following structure to transport the chip holder 3, such as... Figures 2-5 As shown, the second conveying track 13 includes at least: a pair of parallel and spaced track plates 131, multiple conveying shafts 132 arranged along the conveying direction of the chip holder 3, and a rotating device 135.
[0026] like Figure 4 As shown, a pair of parallel spaced track plates 131 define a transport space 15 between the track plates 131 for the chip holder 3 to be transported. The detection mechanism 14 is located above and below the transport space 15 and detects the upper and lower surfaces of the chip holder 3 respectively.
[0027] like Figure 3As shown, the second conveying shaft 132 is rotatably connected to the first track plate 131. One end of the second conveying shaft 132, namely the conveying end 1321, extends into the second conveying space 15. The conveying end 1321 is used to support and convey the chip holder 3. The two ends of the lower surface of the chip holder 3 are supported by the conveying ends 1321 of the second conveying shaft 132 on both sides of the first track plate 131. When the second conveying shaft 132 rotates, it can drive the chip holder 3 to move.
[0028] Of course, in other embodiments, the chip holder 3 can also be transported using a conveyor belt.
[0029] The rotating device 3 135 is connected to the conveying shaft 2 132 for transmission, so as to drive the conveying shaft 2 132 to rotate and drive the chip holder 3 to move in the conveying space 2 15.
[0030] Specifically, the rotating device 3 135 and the conveying shaft 2 132 can be connected by transmission in the following manner, such as... Figure 3 As shown, a transmission wheel 133 is fixedly installed at one end of the second conveyor shaft 132. Two adjacent transmission wheels 133 are connected by a transmission belt 134. Of course, all transmission wheels 133 can also be connected by a single transmission belt. Finally, the rotating device 135 can be connected to one of the second conveyor shafts 132.
[0031] Furthermore, in order to meet the needs of conveying chip holders 3 of different sizes, the conveyor line also includes a transverse mechanism 12, which is used to adjust the spacing between a pair of track plates 131.
[0032] Specifically, the transverse movement mechanism 12 can adopt the following structure to adjust the spacing between the pair of track plates 131, such as... Figures 2-5 As shown, the transverse movement mechanism 12 includes a slide rail 121 and a pair of sliders 123 slidably connected to the slide rail 121. A pair of track plates 131 are respectively mounted and fixed on a slider 123. The pair of sliders 123 are screwed to the same double-ended lead screw 122. By rotating the double-ended lead screw 122, the distance between the pair of sliders 123 can be adjusted, thereby adjusting the distance between the pair of track plates 131.
[0033] To facilitate the rotation of the double-ended lead screw 122, as follows: Figure 4 and Figure 5 As shown, one end of the double-ended lead screw 122 is connected to multiple pulleys 126 via a synchronous belt 124. The multiple pulleys 126 are configured to rotate only. One of the pulleys 126 is connected to a crank 125. By cranking the crank 125, the synchronous belt 124 can be moved, thereby driving the rotation of the double-ended lead screw 122.
[0034] In specific implementation, the detection mechanism 14 can use visual inspection to inspect the chip holder 3, wherein the detection mechanism 14 using visual inspection is as follows: Figures 2-5 As shown, it includes at least a visual camera 142 and a light source 141.
[0035] To facilitate the installation of the transverse movement mechanism 12 and the detection mechanism 14, the chip bracket detection device 1 also has a chassis 11, on which the transverse movement mechanism 12 and the detection mechanism 14 are both installed.
[0036] As can be seen, the chip carrier inspection and receiving equipment in this embodiment can first perform quality inspection on the chip carrier 3 that is about to be unloaded, and then divide the chip carrier 3 into qualified products and unqualified products according to the inspection results, and unqualified products and unqualified products are unloaded separately from different unloading positions, which saves the trouble of unloading and then inspecting online, and improves the overall production efficiency of chip carrier 3.
[0037] In the embodiments disclosed herein, such as Figure 6 As shown, the chip carrier receiving device 2 includes at least: a stacking mechanism 22, a paper picking and placing mechanism 23, a paper storage mechanism 24, and a feeding mechanism 25.
[0038] The stacking mechanism 22 is used to transport the chip carrier 3 from the first conveyor line to the unloading position, and to cause the chip carrier 3 located at the unloading position and the protective paper 3 directly above it to fall. The unloading position includes a qualified product unloading position and a non-qualified product unloading position.
[0039] like Figure 9 and Figure 10 As shown, the stacking mechanism 22 includes at least: a pair of parallel and spaced conveying tracks 221 and a feeding unit 222.
[0040] like Figure 9 As shown, a pair of parallel and spaced conveying tracks 221 define a conveying space 27 between the two conveying tracks 221. The pair of conveying tracks 221 are configured to convey the chip support 3 to move to the unloading position in the conveying space 27.
[0041] The feeding unit 222 is connected to the conveying track 221 and is used to adjust the distance between the pair of conveying tracks 221 so that the chip holder 3 and the protective paper 3 fall. That is, the chip holder 3 and the protective paper 3 are initially located on the pair of conveying tracks 221. When the distance between the pair of conveying tracks 221 increases, the chip holder 3 and the protective paper 3 fall away from the stacking mechanism 22.
[0042] Specifically, the conveying track 221 can adopt the following structure to realize the conveying of the chip holder 3, such as... Figure 9 and Figure 10As shown, the conveying track 221 includes at least: an inner track plate 2212, a conveying shaft 224, and a rotating device 2213.
[0043] like Figure 9 As shown, multiple conveying shafts 224 are rotatably installed on the inner track plate 2212 along the conveying direction of the chip holder 3. One end of the conveying shaft 224 extends into the conveying space 27 to support and convey the chip holder 3. The rotating device 2213 is connected to the conveying shaft 224 to drive the conveying shaft 224 to rotate.
[0044] Of course, in other embodiments, the chip holder 3 can also be transported using a conveyor belt.
[0045] like Figure 10 As shown, the feeding unit 222 includes at least a push-pull device 2221 connected to the inner track plate 2212 / conveyor shaft 224. The push-pull device 2221 drives the inner track plate 2212 / conveyor shaft 224 to move laterally to increase the distance between the pair of conveyor tracks 221, so that the chip bracket 3 and protective paper 3 on them fall down.
[0046] When the conveyor shaft 224 and the inner track plate 2212 are only rotatably connected, the conveyor shaft 224 is used to support and convey the chip holder 3, and the inner track plate 2212 is used to carry the protective paper 3.
[0047] Furthermore, in addition to being rotatably connected to the inner track plate 2212, the conveying shaft 224 is also slidably connected to the inner track plate 2212. At this time, the push-pull device 2221 is connected to the conveying shaft 224 but not to the inner track plate 2212. It does not push the inner track plate 2212 to move laterally. The push-pull device 2221 drives the conveying shaft 224 to move and expand the distance between the conveying shafts 224 on the pair of conveying tracks 221, so that the chip bracket 3 falls.
[0048] At the same time, such as Figure 10 As shown, the conveying track 221 also includes an upper loading plate 2231, which is used to replace the inner track plate 2212 to carry the protective paper 3. The upper loading plate 2231 is connected to the push-pull device 2221. The push-pull device 2221 drives the upper loading plate 2231 to move and expand the distance between the upper loading plates 2231 on the pair of conveying tracks 221, so that the protective paper 3 falls.
[0049] In this embodiment of the disclosure, the unloading position includes a qualified product unloading position and a non-qualified product unloading position, and qualified and non-qualified chip carriers 3 are unloaded separately, such as... Figure 6As shown, there are two feeding mechanisms 25, which are used to transport qualified and unqualified chip carriers 3 respectively. Of course, in other embodiments, a single feeding mechanism 25 can be used to transport qualified and unqualified chip carriers 3 separately.
[0050] Since the inner track plate 2212 has a certain length, in order to improve the material collection efficiency, such as Figure 9 and Figure 10 As shown, with the conveyor shaft 224 slidably connected to the inner track plate 2212, there are two push-pull devices 2221, which are respectively connected to the conveyor shaft 224 of the qualified product unloading position and the unqualified product unloading position. In this way, the chip bracket 3 and the protective paper 3 of the qualified product unloading position and the unqualified product unloading position can fall independently without interfering with each other.
[0051] Of course, if the conveyor shaft 224 is only rotatably connected to the inner track plate 2212, then there can be two inner track plates 2212, located at the qualified product unloading position and the unqualified product unloading position respectively. Similarly, there are two push-pull devices 2221, connected to the inner track plates 2212 / conveyor shaft 224 at the qualified product unloading position and the unqualified product unloading position respectively. This design also allows the chip support 3 and protective paper 3 at the qualified product unloading position and the unqualified product unloading position to fall independently without interference.
[0052] Specifically, the conveying track 221 further includes a material conveying mechanism 225, and the rotating device 2213 and the conveying shaft 224 can be connected by the material conveying mechanism 225 for transmission. Figure 9 and Figure 10 As shown, an outer track plate 2211 is spaced apart on the side of the inner track plate 2212 away from the conveying space 27. A wheel axle 2252 is rotatably mounted on the outer track plate 2211. A drive wheel 2253 is mounted at one end of the wheel axle 2252, and a transmission wheel 2254 is mounted at the other end. Adjacent transmission wheels 2254 are connected by a transmission belt 2255. Figure 9 As shown, one of the transmission wheels, 2254, is connected to the rotating device, 2213, via a transmission connection. Figure 10 As shown, a driven wheel 2251 is installed at one end of the conveyor shaft 224. The driven wheel 2251 meshes with the driving wheel 2253. With this design, the rotating device 2213 can drive the drive wheel shaft 2252 to rotate, thereby driving the conveyor shaft 224 to rotate.
[0053] When the design of conveyor shaft 224 being slidably connected to inner track plate 2212 is adopted, in order to ensure smooth transmission, driven wheel 2251 can be slidably connected to conveyor shaft 224, or driven wheel 2251 can move axially relative to driving wheel 2253.
[0054] When the design of conveyor shaft 224 being slidably connected to the inner track plate 2212 is adopted, in order to make multiple conveyor shafts 224 slide axially synchronously, such as Figure 10 As shown, the conveying track 221 also includes a movable track plate 223, which is located between the inner track plate 2212 and the outer track plate 2211. The conveying shaft 224 is rotatably mounted on the movable track plate 223. Meanwhile, to facilitate the connection between the push-pull device 2221 and the upper loading plate 2231, the upper loading plate 2231 can be fixedly mounted on the upper surface of the movable track plate 223.
[0055] Furthermore, to ensure the protective paper 3 falls smoothly and does not drift around, such as Figure 10 As shown, a sliding groove 22121 is provided at the upper end of the inner track plate 2212, and part of the structure of the upper loading plate 2231 slides through the sliding groove 22121 and extends into the conveying space 27.
[0056] To ensure that the push-pull device 2221 smoothly moves the track plate 223 laterally, such as Figure 10 As shown, the feeding unit 222 also includes a connecting rod 2222 connected to the movable end of the push-pull device 2221. Slide rods 2223 are evenly distributed on the moving track plate 223. The slide rods 2223 are slidably connected to the outer track plate 2211 and fixedly connected to the connecting rod 2222. The push-pull device 2221 is fixedly connected to the outer track plate 2211. The push-pull device 2221 pushes the slide rods 2223 to slide, thereby driving the moving track plate 223 to move smoothly laterally.
[0057] Furthermore, to accommodate the transport of chip holders 3 of different sizes, the first transport track 221 also includes a second transverse mechanism 28, which is used to adjust the spacing between a pair of inner track plates 2212. Specifically, the second transverse mechanism 28 can adjust the spacing between the pair of inner track plates 2212 using the following structure: Figure 9 As shown, the transverse movement mechanism 28 includes a slide rail 281 and a pair of spaced-apart seat plates 2214 slidably connected to the slide rail 281. A pair of inner track plates 2212 are respectively connected to a seat plate 2214. The pair of seat plates 2214 are screwed to the same double-ended lead screw 282. The rotation of the double-ended lead screw 282 can make the pair of seat plates 2214 move closer or further apart on the slide rail 281, thus adjusting the distance between the pair of inner track plates 2212.
[0058] In this embodiment, furthermore, to ensure that the chip carrier 3 and the protective paper 3 directly above it are neatly stacked together after falling, and that subsequent chip carriers 3 and the protective paper 3 directly above them are also neatly stacked on top of the aforementioned chip carrier 3 and protective paper 3 after falling, facilitating material collection, as follows... Figure 10As shown, the stacking mechanism 22 also includes a front baffle mechanism 220 and a rear baffle mechanism 229 arranged sequentially in the conveying space 27 along the conveying direction of the chip carrier 3. The front baffle mechanism 220 and the rear baffle mechanism 229 are located on both sides of the unloading position. With this design, the front and rear sides of the chip carrier 3 and the protective paper 3 are limited by the front baffle mechanism 220 and the rear baffle mechanism 229, and the left and right sides of the chip carrier 3 and the protective paper 3 are limited by the inner track plate 2212. This ensures that the chip carrier 3 and the protective paper 3 above it are neatly stacked together after falling from the unloading position, and that the chip carrier 3 and the protective paper 3 above it are also neatly stacked on the aforementioned chip carrier 3 and protective paper 3 after falling from the unloading position.
[0059] Specifically, the front gauge mechanism 220 can achieve the limiting function using the following structure, such as... Figure 10 and Figure 11 As shown, the front feed mechanism 220 includes a second mounting frame 2201 and a first axle 2202 rotatably mounted on the second mounting frame 2201. A gear 2203 is mounted on the first axle 2202. A rack 2204 is slidably mounted on the second mounting frame 2201 along the conveying direction of the chip carrier 3. The rack 2204 meshes with the gear 2203. With this design, driving the first axle 2202 to rotate will drive the rack 2204 to move. Figure 11 As shown, a vertical front stop bar 2205 is provided at one end of the rack 2204 near the unloading position, which limits the chip bracket 3 and the protective paper 3.
[0060] Furthermore, such as Figure 11 As shown, the upper end of the side of the front stop 2205 facing the unloading position is a guide slope 2206. The guide slope 2206 facilitates the sliding contact between the chip holder 3 and the protective paper 3 and the side of the front stop 2205 facing the unloading position, so that the chip holder 3 and the protective paper 3 directly above it fall neatly and stack together, and the subsequent chip holder 3 and the protective paper 3 directly above it also fall neatly and stack on the aforementioned chip holder 3 and protective paper 3.
[0061] Specifically, the back gauge mechanism 229 can achieve the limiting function using the following structure, such as... Figure 10 As shown, the back gauge mechanism 229 includes a back gauge 2291 and a lifting device 2292 connected to the back gauge 2291. The lifting device 2292 drives the back gauge 2291 to rise and stop the chip support 3 from being conveyed by the conveyor shaft 224.
[0062] As can be seen, the chip carrier detection and receiving equipment of this embodiment is equipped with a paper picking and placing mechanism 23 and a stacking mechanism 22. The paper picking and placing mechanism 23 can quickly pick up the protective paper 3 and place the protective paper 3 in advance directly above the unloading position of the qualified and unqualified chip carriers 3 on the stacking mechanism 22. After the chip carrier 3 moves to the unloading position, the stacking mechanism 22 can immediately make the chip carrier 3 and the protective paper 3 fall and stack them without waiting, which greatly shortens the stacking time and improves the receiving efficiency.
[0063] In the embodiments disclosed herein, such as Figure 9 As shown, the stacking mechanism 22 also includes a position sensor 228 for detecting the position of the chip carrier 3 so as to accurately control the conveyor shaft 224 to stop conveying and further improve the receiving accuracy of the chip carrier 3. For example, the position sensor 228 can be set to be detected when the chip carrier 3 moves to the unloading position.
[0064] To facilitate the installation of the stacking mechanism 22, the paper loading and unloading mechanism 23, the paper storage mechanism 24, and the feeding mechanism 25, such as Figure 6 As shown, the chip carrier receiving device 2 also includes a second chassis 21, and a stacking mechanism 22, a paper picking and placing mechanism 23, a paper storage mechanism 24, and a feeding mechanism 25 are installed on the second chassis 21.
[0065] In this embodiment, the paper pick-and-place mechanism 23 is used to pick up the protective paper 3 and place it on the stacking mechanism 22 directly above the chip holder 3 at the unloading position. Specifically, the protective paper 3 is placed on a pair of upper loading plates 2231.
[0066] Preferably, the specific structure of the paper picking and placing mechanism 23 is as follows: Figure 6 As shown, the paper picking and placing mechanism 23 includes at least a second rotating device 230, a swing arm 239, a first mounting frame, and a suction nozzle 238. The output shaft of the second rotating device 230 is fixedly connected to one end of the swing arm 239, and the other end of the swing arm 239 is rotatably connected to the first mounting frame. The first mounting frame is configured to maintain its posture during the swinging process driven by the second rotating device 230. The suction nozzle 238 is located below the first mounting frame and is connected to the first mounting frame. The second rotating device 230 drives the swing arm 239 to swing, causing the suction nozzle 238 to move to the paper storage mechanism 24 to pick up the protective paper 3, and then place the protective paper 3 on the stacking mechanism 22 directly above the chip support 3 located at the unloading position.
[0067] The mounting frame is designed to maintain its posture during the swing of the swing arm 239 driven by the rotating device 230. That is, the mounting frame does not shake during the swing of the swing arm 239, and the suction nozzle 238 always maintains the posture of being able to suck up the protective paper 3.
[0068] As can be seen, the paper picking and placing mechanism 23 in this embodiment completes paper picking by driving the swing arm 239 to swing through the rotating device 230. The paper picking and placing mechanism 23 adopts a swing arm rotation design, and the paper picking path can be constructed into an arc. Compared with the paper picking and placing mechanism 23 of the traditional three-axis robot, the paper picking path is shorter, the paper picking speed is faster, and the efficiency is higher, which further improves the material collection efficiency.
[0069] Furthermore, to improve the attitude stability of mounting bracket one during the swing of swing arm 239, such as... Figure 6 As shown, the paper loading and unloading mechanism 23 also includes a frame 231, a horizontal slide rail 233, a vertical slide rail 234, and a slider 235. The rotating device 230 is fixedly connected to the frame 231. The horizontal slide rail 233 is horizontally fixedly installed on the frame 231. The vertical slide rail 234 is vertically set and is horizontally slidably connected to the horizontal slide rail 233. The slider 235 is vertically slidably connected to the vertical slide rail 234. At the same time, the slider 235 is rotatably connected to the other end of the swing arm 239. The mounting frame 1 is connected to the slider 235. With this design, the horizontal slide rail 233 and the vertical slide rail 234 help the slider 235 maintain a stable posture during the swing of the swing arm 239, which also helps the mounting frame 1 maintain a stable posture.
[0070] Furthermore, to facilitate the paper handling mechanism 23 in handling the protective paper 3, the paper handling mechanism 23 also includes a lifting device 236. The mounting frame 1 is connected to the lifting device 236, which drives the mounting frame 1 to rise and fall. The lifting device 236 is fixedly connected to the slider 235. When the rotating device 230 drives the swing arm 239 to swing and move the suction nozzle 238 to directly above the paper storage mechanism 24, the lifting device 236 drives the suction nozzle 238 to descend and suck up the protective paper 3. When the rotating device 230 drives the swing arm 239 to swing and move the suction nozzle 238 to directly above the chip support 3 located at the unloading position on the stacking mechanism 22, the lifting device 236 drives the suction nozzle 238 to descend and place the protective paper 3 directly above the chip support 3 located at the unloading position on the stacking mechanism 22. With this design, the handling of the protective paper 3 is more reliable, stable, and convenient compared to the case without the lifting device 236.
[0071] Preferably, the mounting bracket is a pair of mounting rods 237, such as Figure 6 As shown, a pair of mounting rods 237 are connected to the lifting device 236, and the spacing between the pair of mounting rods 237 is adjustable. The suction nozzle 238 is located below the mounting rods 237. By adjusting the spacing between the pair of mounting rods 237, the suction operation of protective paper 3 of different sizes can be better met, making the picking and placing of protective paper 3 more stable. When a protective plate is attached to the outside of the frame 231, an arc-shaped through hole 232 needs to be opened on the protective plate so that the slider 235 and the swing arm 239 can be connected. Figure 6 As shown, this is to form an arc-shaped paper-taking path.
[0072] In this embodiment, the paper storage mechanism 24 is used to supply paper to the paper dispensing mechanism 23. Specifically, the structure of the paper storage mechanism 24 is as follows: Figure 7 and Figure 8 As shown, the paper storage mechanism 24 includes at least a base plate 249 and a lifting device 240 connected to the base plate 249. The protective paper 3 is neatly stacked on the base plate 249. The lifting device 240 drives the base plate 249 to rise in a timely manner, so that the uppermost protective paper 3 is in a position that can be sucked away by the suction nozzle 238.
[0073] Furthermore, to ensure that the protective paper 3 is neatly stacked and placed on the base plate 249, such as... Figure 7 As shown, the base plate 249 is provided with a vertical baffle 248, a first vertical rod 245, and a second vertical rod 247. The baffle 248, the first vertical rod 245, and the second vertical rod 247 are located on different sides of the protective paper 3. That is, the stacked protective paper 3 is located between the baffle 248, the first vertical rod 245, and the second vertical rod 247, thereby limiting the protective paper 3 and keeping it stacked neatly.
[0074] Furthermore, to ensure that baffle 248, vertical rod one 245, and vertical rod two 247 are suitable for protective paper 3 of different specifications and sizes, such as Figure 7 As shown, the lower ends of the vertical rods 245 located on the front and rear sides of the protective paper 3 are respectively connected to a slide block 241. The pair of slide blocks 241 are screwed to the double-ended lead screw 243. The end of the double-ended lead screw 243 is connected to the crank handle 244. The crank handle 244 drives the double-ended lead screw 243 to rotate, which in turn drives the pair of slide blocks 241 to move closer or further apart, thereby adjusting the distance between the vertical rods 245 on the front and rear sides of the protective paper 3.
[0075] At the same time, such as Figure 7 As shown, the lower end of the second vertical rod 247 located on the right side of the protective paper 3 is screwed to the drive screw 246. The rotation of the drive screw 246 drives the second vertical rod 247 to move horizontally left or right. Adjusting the distance between the second vertical rod 247 and the baffle 248 allows them to be positioned on the left and right sides of the protective paper 3. This allows the baffle 248, the first vertical rod 245, and the second vertical rod 247 to be suitable for protective papers 3 of different sizes.
[0076] To facilitate the installation of slide 241, double-ended lead screw 243, and drive lead screw 246, such as Figure 7 As shown, the paper storage mechanism 24 also includes a mounting frame 242, on which a track is provided, and a slide 241 is slidably mounted on the track. The mounting frame 242 and the lifting device 240 are fixedly connected to the housing 21.
[0077] In the embodiments disclosed herein, such as Figure 6As shown, the unloading mechanism 25 is located below the stacking mechanism 22 and is used to receive the chip carrier 3 and protective paper 3 from the stacking mechanism 22, and to send the chip carrier 3 and protective paper 3 away. Specifically, the unloading mechanism 25 includes at least a second conveyor line, on which the chip carrier 3 located at the unloading position and the protective paper 3 directly above it fall and are sent away by the second conveyor line.
[0078] Furthermore, after the chip holder 3 located at the unloading position and the protective paper 3 directly above it fall onto the second conveyor line, they are not immediately sent away. Instead, they are stacked on the second conveyor line to form a stack of chip holders 3 and protective paper 3, which are alternately stacked. This design saves the trouble of manually stacking and collecting the chip holders 3 later.
[0079] To improve stacking quality, such as Figure 11 As shown, the unloading mechanism 25 also includes a lifting device 26 and a carrying rod 261 located above and connected to the lifting device 26. The lifting end of the lifting device 26 is connected to the carrying rod 261. The carrying rod 261 is configured to rise above the conveyor line 2 under the drive of the lifting device 26 to receive the falling chip holder 3 and protective paper 3, thereby shortening the falling distance of the chip holder 3 and protective paper 3, improving the stacking quality, and making the chip holder 3 and protective paper 3 stacked neatly. At the same time, the carrying rod 261 is also configured to descend below the conveyor line 2 to place the received chip holder 3 and protective paper 3 onto the conveyor line 2, and finally the conveyor line 2 will send the stacked chip holder 3 and protective paper 3 away.
[0080] To enable the material carrier rod 261 to rise and fall beside the second conveyor line without affecting its operation, the second conveyor line can adopt the following specific structure, such as... Figure 6 As shown, conveyor line two includes frame two 254 and a drive shaft 251 rotatably connected to frame two 254. Multiple conveyor belts 253 are spaced along the drive shaft 251. The drive shaft 251 is connected to the rotating device four 252 via a transmission mechanism. Figure 11 As shown, the frame 254 is also provided with a through hole 255. The through hole 255 is located between two adjacent conveyor belts 253. This design allows the material carrier rod 261 to move up and down through the through hole 255, so that it can rise above the conveyor line 2 under the drive of the lifting device 26 to receive the falling chip bracket 3 and protective paper 3, and fall below the conveyor line 2 to place the received chip bracket 3 and protective paper 3 onto the conveyor line 2, without affecting the conveyor line 2's transport of the chip bracket 3 and protective paper 3.
[0081] Correspondingly, such as Figure 10 and Figure 11As shown, the stacking mechanism 22 also has a loading plate 227 and a push-pull device 226 connecting the loading plate 227. The loading plate 227 is configured to extend into the falling path of the chip holder 3 under the drive of the push-pull device 226, so as to temporarily support the falling chip holder 3 and protective paper 3 in place of the loading rod 261 during the descent and ascent to the loading position. The loading plate 227 extending into the falling path of the chip holder 3 is at the same height as the loading rod 261 at the loading position. This design ensures the stacking quality without stopping the chip holder detection and receiving equipment. When the loading rod 261 rises to the loading position, the loading plate 227 leaves the conveying space 27 and resets, restoring the support of the falling chip holder 3 and protective paper 3 by the loading rod 261.
[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
