[0032] Reference Figure 1 The counting machine of this utility model embodiment includes a worktable 11, a carrier track 5, an image recording structure 2, and a control structure. The worktable 11 provides an installation position for the carrier track 5 and the image recording structure 2. The carrier track 5 is disposed on the worktable 11 and is used to position and guide the movement of the carrier track, so that the image recording structure 2 can acquire images of the carrier track. The image recording structure 2 is mounted on the worktable 11 and located above the carrier track 5, and is used to acquire images of the carrier track to count and detect the chips on the carrier track 5. The control structure is installed inside the worktable 11, and an electrical structure is installed inside the worktable 11 to facilitate electrical control of the counting machine. The control structure is electrically connected to the image recording structure 2 and controls the image recording structure 2 to acquire images of the carrier track. By analyzing the images of the carrier track, the control structure can identify the quantity and quality of the chips on the carrier track, enabling faster counting and quality verification of the chips, reducing manpower consumption, and improving production efficiency.

[0033] Specifically, refer to Figure 2 , Figure 3 , Figure 4The image recording structure 2 includes a lens support assembly, a lens fixing assembly 21, and a lens assembly. The lens support assembly is located above the carrier track 5, supporting the installation of the lens fixing assembly 21 and the lens assembly, and providing support and guidance for position adjustment of the lens fixing assembly 21 and the lens assembly. The lens fixing assembly 21 is connected to the lens support assembly, fixing the lens assembly and providing installation space to facilitate the replacement of different lens assemblies according to different image acquisition needs. To improve the quality of acquired images and reduce the influence of the external environment, in some embodiments, the lens fixing assembly 21 is formed as a housing consisting of a lens side plate, front and rear lens plates, and a lens top cover, to enclose the lens assembly as much as possible without affecting its operation, isolating it from external influencing factors. The lens assembly is disposed within the lens fixing assembly 21 and is used to acquire images from the carrier tape. Depending on the actual situation, to more accurately count and identify chips, different lens assemblies are used for imaging different chips to be tested. An industrial camera is typically used as the lens assembly for image acquisition.

[0034] Due to the different specifications of various carriers and chips, in order to obtain a clearer image for recognition, it is necessary to adjust the position of the lens assembly to ensure accurate focusing and complete acquisition of the chip structure. In some embodiments, refer to Figures 2-4 The image recording structure 2 also includes an illumination assembly 29, a guide rod 25, a limiting seat 27, and a movable bracket 28. The guide rod 25 is mounted on the worktable 11 and connected to the lens support assembly, passing through the limiting seat 27. In effect, the guide rod 25 provides support for the installation of the lens support assembly and the limiting seat 27, and guides their movement. The movable bracket 28 is movably connected to the limiting seat 27 on the side facing the carrier track 5, and the illumination assembly 29 is movably connected to the movable bracket 28. The illumination assembly 29 is positioned via the movable bracket 28 and cooperates with the lens assembly to provide illumination for the lens assembly, thereby obtaining a clearer and more recognizable image.

[0035] To clearly describe the connection and movement direction of each component of the image recording structure 2, a spatial rectangular coordinate system is established with the length of the carrier track 5 as the x-axis, the direction perpendicular to the length of the carrier track 5 on the horizontal plane as the y-axis, and the direction perpendicular to the horizontal plane as the z-axis.

[0036] like Figure 3 , Figure 4 As shown, the lens support assembly includes a movable part 22, a lens bracket 26, and an adjusting screw 23. A guide rod 25 passes through the movable part 22, the adjusting screw 23 is connected to the movable part 22, the lens bracket 26 is connected to the movable part 22, and the lens fixing assembly 21 is connected to the lens bracket 26.

[0037] Among them, reference Figure 3 , Figure 4 The lens bracket 26 is a structure that guides the lens assembly to move in the x-axis and y-axis directions. Specifically, the lens bracket 26 is formed into an L-shape. The first and second moving structures of the lens bracket 26 are perpendicular to each other. The first moving structure has a lens moving groove perpendicular to the length direction of the carrier track 5, i.e., the y-axis direction. The lens fixing assembly 21 is connected in the lens moving groove to position the lens fixing assembly 21 and the lens bracket 26 in the y-axis direction. The second moving structure is connected to the moving member 22 and has a first bracket moving groove extending along the x-axis direction to position the lens bracket 26 and the moving member 22 in the x-axis direction. Bolt holes are respectively provided on the front plate of the lens fixing assembly 21 and the moving member 22. By inserting bolts into the moving groove and screwing them into the bolt holes for fastening, the lens bracket 26 is fixed to the lens fixing assembly 21 and the moving member 22. Changing the position of the bolts inserted into the moving groove will change the final position of the lens assembly. Depending on the actual situation, in order to avoid obstructing the lens of the lens assembly, there are usually two lens moving slots, which are arranged on the lens bracket 26 at positions corresponding to both sides of the lens assembly, so that the bolts screwed into the moving slots avoid the lens of the lens assembly.

[0038] Furthermore, such as Figure 3 As shown, the movable component 22, guide rod 25, and adjusting screw 23 together form a structure for guiding the lens assembly to move in the z-axis direction. In the z-axis direction, the guide rod 25 is fixed in position and guides the movement of the movable component 22. The adjusting screw 23 converts rotation into linear motion via a thread, driving the movable component 22 to move in the z-axis direction. Depending on the actual situation, the adjusting screw 23 can be rotated in place, passing through the movable component 22 and threadedly connected to it, so that when the adjusting screw 23 is rotated, the movable component 22 can move up and down along the thread of the adjusting screw 23; alternatively, the adjusting screw 23 can move itself, rotatingly connected to the movable component 22, so that when the adjusting screw 23 is rotated, the movable component 22 moves up and down with the movement of the adjusting screw 23.

[0039] This embodiment uses the method of adjusting screw 23 moving itself and driving moving part 22 to move, specifically, as follows: Figure 3As shown, the lens support assembly also includes a reinforcing block 24 to support the movement of the adjusting screw 23. There are two guide rods 25, and the reinforcing block 24 is connected to the top of the two guide rods 25, fixing the position of the reinforcing block 24. The adjusting screw 23 passes through the reinforcing block 24 and is threadedly connected to it. The adjusting screw 23 is located between the two guide rods 25 and is rotatably connected to the top of the moving part 22. The moving part 22 moves along the length of the guide rods 25, ultimately adjusting the position of the lens assembly. The position of the lens assembly is determined before image acquisition, and the lens assembly does not change position during the use of the counting machine.

[0040] Reference Figure 4 The lighting component 29 is movably connected to the movable bracket 28. The position of the lighting component 29 is adjusted via the movable bracket 28, and it works in conjunction with the lens assembly to provide illumination for the lens assembly, resulting in a clearer and more identifiable image. The movable bracket 28 is movably mounted on the limiting seat 27, allowing the lighting component 29 to have a wider adjustment range. Depending on the actual situation, the lighting component 29 can be selected with a lamp holder that has a hollow center to avoid obstructing the lens assembly's shooting. A light strip is set on the lamp holder to form a uniform ring-shaped illumination.

[0041] like Figure 4 As shown, the movable bracket 28 is a structure that guides the lighting component 29 to move in the x-axis and y-axis directions. Specifically, the movable bracket 28 is formed into an L-shape, with two parts perpendicular to each other. The first part has an adjustment groove perpendicular to the length direction of the carrier track 5, i.e., the y-axis direction. The lighting component 29 is connected in the adjustment groove to position the movable bracket 28 and the lighting component 29 in the y-axis direction. The second part is connected to the limiting seat 27 and has a second bracket movement groove extending along the x-axis direction to position the movable bracket 28 and the limiting seat 27 in the x-axis direction. The limiting seat 27 has a limiting groove parallel to the length direction of the carrier track 5, i.e., the x-axis direction. The second part of the movable bracket 28 is connected in the limiting groove to achieve a movable connection with the limiting seat 27. Bolt holes are provided in the limiting groove. By inserting bolts into the moving groove and screwing them into the bolt holes for fastening, the movable bracket 28 and the limiting seat 27 are fixed. Changing the position of the bolts inserted into the moving groove changes the final position of the lighting component 29.

[0042] The limiting seat 27 is a structure that guides the movement of the lighting assembly 29 in the z-axis direction. A guide rod 25 passes through the limiting seat 27 and guides its movement in the z-axis direction, allowing the limiting seat 27 to move along the guide rod 25 in this direction. Since the limiting seat 27 is located below the moving member 22, and both the limiting seat 27 and the moving member 22 are penetrated by the guide rod 25, the adjustable range of the limiting seat 27 in the z-axis direction is affected by the position of the moving member 22. A through hole is provided on the limiting seat 27 at a position corresponding to the guide rod 25. By screwing in a bolt and engaging with the guide rod 25, the moving bracket 28 is positioned, ultimately allowing for the adjustment of the lighting assembly 29's position. The position of the lighting assembly 29 is determined before image acquisition and remains unchanged during the use of the counting machine.

[0043] In some embodiments, refer to Figure 2 , Figure 3 , Figure 5 The counting machine also includes a marking structure 3 for marking problematic chips on the carrier tape. The marking structure 3 is mounted on the worktable 11, located behind the image recording structure 2 along the running direction of the carrier tape track 5, to facilitate timely marking of the corresponding problematic chips in the carrier tape image. A control structure is electrically connected to the marking structure 3 and controls the marking structure 3 to mark the problematic chips on the carrier tape, further improving production efficiency.

[0044] Specifically, refer to Figure 5 The marking structure 3 includes a marking guide rail 32, an electromagnetic component 31, a marking slider 34, and a marking pen 33. The marking guide rail 32 is mounted on the worktable 11 and guides the movement of the marking pen 33. The electromagnetic component 31 is connected to the top of the marking guide rail 32 and provides and removes the magnetic force attracting the marking slider 34. Depending on the actual situation, an electromagnet is usually used as the electromagnetic component 31 to control its magnetic force by switching it on and off. The marking slider 34 is connected to the marking guide rail 32 and is located below the electromagnetic component 31. The marking pen 33 is connected to one side of the marking slider 34 and is located above the carrier tape track 5, allowing the marking slider 34 to move the marking pen 33 along the marking guide rail 32 and mark the problematic chips on the carrier tape track 5. When the electromagnetic component 31 is energized, it attracts the marking slider 34 to move. When marking a corresponding chip is required, the electromagnetic component 31 is de-energized, the marking slider 34 loses its magnetic pull and moves downwards, causing the marking pen 33 to move down and contact the carrier tape, thus completing the marking.

[0045] Figure 7 for Figure 6 A magnified schematic diagram of the local structure of the midpoint counting machine after being sectioned along the AA direction.

[0046] Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 The carrier track 5 includes a fixed track 54, a movable track 51, and a track screw 61. The fixed track 54 and movable track 51 are mounted parallel to each other on the worktable 11 for positioning and supporting the carrier track. By changing the distance between the movable track 51 and the fixed track 54, the carrier track 5 can better adapt to carrier tracks of different widths and provide effective positioning. The track screw 61 is rotatably connected to the fixed track 54, passing through the movable track 51 and threadedly connected to it. When the track screw 61 is rotated, it rotates in place within the fixed track 54, and the movable track 51 moves along the thread of the track screw 61 on the worktable 11, thus adjusting the distance between it and the fixed track 54. Specifically, one end of the track screw 61 extending into the fixed track 54 has a non-threaded limiting part 62; when the track screw 61 is rotated, the limiting part 62 rotates in place within the fixed track 54.

[0047] It should be understood that the above is only one embodiment and is not intended to be limiting. The track screw 61 can also be threadedly connected to the fixed track 54 and rotatably connected to the movable track 51, limiting its position so that the movable track 51 can move synchronously with the track screw 61 without rotating. At this time, rotating the track screw 61 causes it to rotate and move in a direction perpendicular to the length of the fixed track 54, and the movable track 51 moves accordingly, thus adjusting the distance between it and the fixed track 54.

[0048] In some embodiments, refer to Figure 2 The carrier track 5 also includes a track guide rod 55, which guides the movement of the movable track 51 and prevents disruption of the parallelism between the fixed track 54 and the movable track 51 during movement. The track guide rod 55 is connected to the fixed track 54, perpendicular to the fixed track 54, and passes through the movable track 51. Depending on the actual situation, the track guide rod 55 is usually marked with common carrier tape width dimensions as a standard, such as different scales along its length, to facilitate convenient and quick positioning when adjusting the spacing.

[0049] In some embodiments, refer to Figure 2On opposite sides of the fixed track 54 and the movable track 51, a first guide protrusion 53 and a second guide protrusion 52 are respectively formed. The ends of the first guide protrusion 53 and the second guide protrusion 52 are rounded edges. The top surfaces of the first guide protrusion 53 and the second guide protrusion 52 are at the same height and lower than the top surfaces of the fixed track 54 and the movable track 51. In other words, the first guide protrusion 53 and the fixed track 54 form a receiving track for the carrier belt, and the rounded edges prevent the carrier belt from breaking due to friction from the sharp edges after tensioning. Similarly, the second guide protrusion 52 and the movable track 51 form a receiving track for the carrier belt, and the rounded edges also prevent the carrier belt from breaking due to friction from the sharp edges after tensioning. Depending on the actual situation, the thickness of the first guide protrusion 53 and the second guide protrusion 52 can be the same or different, but the rounded edges at both ends are symmetrically arranged to facilitate fitting.

[0050] In some embodiments, such as Figure 1 As shown, the carrier track 5 also includes a taping pressure plate 56 for top positioning of the carrier tape, preventing it from sliding out of the receiving track between the fixed track 54 and the movable track 51. The taping pressure plate 56 is located below the marking structure 3 and the image recording structure 2, separating the carrier tape from the image recording structure 2 and the marking structure 3 to prevent mutual interference. The taping pressure plate 56 has a first through hole and a second through hole. The first through hole corresponds to the position of the marking structure 3, and the second through hole corresponds to the position of the image recording structure 2. For the first through hole, when marking is required, the marking structure 3 contacts the carrier tape through the first through hole to complete the marking. For the second through hole, when an image needs to be acquired, the corresponding carrier tape and chip move to the position corresponding to the second through hole, the illumination component 29 of the image recording structure 2 provides illumination, and the lens assembly captures the image to obtain the corresponding carrier tape image.

[0051] In some embodiments, refer to Figure 1 The carrier track 5 also includes a track clamping plate 58, which is connected to the top surfaces of both ends of the fixed track 54 and the movable track 51. The track clamping plate 58 is used to further limit the movable track 51, allowing it to move along the space formed by the track clamping plate 58 and the surface of the worktable 11, and to limit the carrier tape entering between the fixed track 54 and the movable track 51, so as to avoid problems such as bulging or slipping at the edges, as well as affecting the image acquisition accuracy and causing unnecessary chip wear.

[0052] Reference Figure 1 , Figure 8The counting machine also includes two carrier belt structures for winding and unwinding the carrier belt, enabling automatic unloading. The two carrier belt structures are connected to both ends of the worktable 11 along the length of the carrier belt track 5, and are aligned with the track 5 to reduce quality issues such as unclear images caused by carrier belt tilting, bending, or bulging. Each carrier belt structure includes a drive assembly 75 and a limit disc assembly. The drive assembly 75 is connected to the limit disc assembly and drives it to rotate. The two carrier belt structures work together to wind and unwind the carrier belt, and to tighten both ends of the belt to a certain extent, preventing it from slipping off. The drive assembly 75 is electrically connected to the control structure and configured to operate under its control. Depending on the specific situation, the drive assembly 75 is typically a motor.

[0053] In some embodiments, refer to Figures 8-11 Each carrier belt structure also includes a carrier belt axle 72 and an outer positioning assembly 4. The carrier belt axle 72 is used to mount the limiting disc assembly and provide anchor points for the winding of the carrier belt. The limiting disc assembly is adjustablely mounted on the carrier belt axle 72 to accommodate more carrier belt widths. The drive assembly 75 is connected to the carrier belt axle 72 and drives the limiting disc assembly to rotate via the carrier belt axle 72. The rotation is further transmitted to the carrier belt, enabling the feeding and unloading of the carrier belt on both sides of the worktable 11. The outer positioning assembly 4 is used to fix the position of the limiting disc assembly, increasing structural stability and supporting the adjustment of the spacing of the limiting disc assembly to adapt to different widths of carrier belts. Each outer positioning assembly 4 of the drive assembly 75 is connected to the side of the corresponding limiting disc assembly away from the drive assembly 75, so that the position of the limiting disc assembly close to the drive assembly 75 is fixed, facilitating the connection between the drive assembly 75 and the limiting disc assembly while allowing for some adjustment of the spacing between the inner disc 76 and the outer disc 71 within the limiting disc assembly.

[0054] like Figures 9-11 As shown, the outer positioning assembly 4 includes a positioning disc 41 and a positioning plate 42. The positioning disc 41 is used to connect with the limiting disc assembly, and the positioning plate 42 is used to cooperate with the carrier pulley axle 72 to position the positioning disc 41. Specifically, the inner side of the positioning disc 41 has a receiving groove 48 and a locking groove 45. The locking groove 45 is located at one end of the receiving groove 48 and communicates with the receiving groove 48. The side of the receiving groove 48 away from the locking groove 45 extends to the edge of the positioning disc 41 to form an open opening. The positioning plate 42 is C-shaped, with one end connected to the receiving groove 48 and the locking groove 45. The width of the locking groove 45 is greater than the thickness of the end of the positioning plate 42 that extends into the locking groove 45, allowing the positioning plate 42 to slide along the length of the receiving groove 48 within the receiving groove 48 and the locking groove 45.

[0055] The positioning disk 41 has a first positioning through hole 49. Depending on the actual situation, the first positioning through hole 49 is usually located at the center of the positioning disk 41, and the carrier pulley axle 72 passes through the first positioning through hole 49. The positioning plate 42 is used to position and fix the positioning disk 41. Figure 10 , Figure 11 As shown, the positioning plate 42 has a second positioning through hole 46 and a positioning groove 47. The diameter of the second positioning through hole 46 is the same as the diameter of the first positioning through hole 49, and the diameter of the positioning groove 47 is smaller than the diameter of the second positioning through hole 46. The carrier pulley shaft 72 has multiple positioning ring grooves 74, the width of each positioning ring groove 74 corresponding to the thickness of the positioning plate 42. When the positioning groove 47 is engaged in the positioning ring groove 74, the position of the positioning plate 42 is limited along the length of the carrier pulley shaft 72, and the positions of the positioning disc 41 and the limiting disc assembly are further limited.

[0056] To further locate the position of positioning plate 42, refer to Figure 9 , Figure 10 A through locking hole 43 is provided at the corresponding position of the positioning plate 41 and the locking groove 45. The bolt is screwed into the locking hole 43, and the end of the bolt extending into the locking groove 45 can abut against one end of the positioning plate 42. As the bolt is screwed in further, the positioning plate 42 is pushed by the bolt to slide along the receiving groove 48 to the positioning groove 47 and lock into the positioning ring groove 74. At this time, the entire outer positioning assembly 4 is locked.

[0057] Reference Figure 8 , Figure 12 The limiting disc assembly includes an inner disc 76 and an outer disc 71. A disc gap is formed between the outer disc 71 and the inner disc 76, and the carrier belt is placed within the disc gap and wound around the carrier belt axle 72. The inner disc 76 is connected to the carrier belt axle 72, has a fixed position, and is driven to rotate by the carrier belt axle 72. The outer disc 71 is connected to the positioning disc 41 on its outer side. Depending on the actual width of the carrier belt, the outer disc 71 can change its position to adapt to the width of the carrier belt. The connection between the outer disc 71 and the positioning disc 41 is achieved by bolts. Specifically, the positioning disc 41 has a second connecting hole 44, and the outer disc 71 has a first connecting hole 73. The bolts connect the first connecting hole 73 and the second connecting hole 44 to achieve the connection between the positioning disc 41 and the outer disc 71. Depending on the actual situation, the first connecting hole 73 is usually a countersunk threaded hole to avoid sharp edges on the part of the outer disc 71 that contacts the carrier belt, thus avoiding any impact on the carrier belt. It should be understood that the above is only one embodiment and is not intended to be limiting. The connection between the outer wheel 71 and the positioning plate 41 can also be achieved by snap-fit ​​or other means, and is not limited to bolt connection.

[0058] In some embodiments, such as Figure 1As shown, the worktable 11 includes a worktable body and a display base 14. The display base 14 is connected to the top surface of the worktable body and is used to mount external structures such as a display screen. Specifically, the display base 14 is connected to the top of the worktable body via a support frame 12, so as to keep the display base 14 away from the worktable body and avoid the influence of external light from the display screen or other sources on the acquisition of the carrier image. In some embodiments, extension arms 13 are also connected to both sides of the worktable body, and two carrier structures are respectively connected to the ends of the two extension arms 13.

[0059] In some embodiments, the carrier track 5 further includes a sensor for detecting the carrier tape. Specifically, the sensor is mounted on the worktable 11, located in front of the image recording structure 2 along the running direction of the carrier track 5, to detect whether the carrier tape is misaligned. A third through hole is provided on the tape pressing plate 56 at a position corresponding to the sensor to facilitate the sensor's detection of the carrier tape.

[0060] Reference Figures 1-7 Before using the counting machine, adjust the positions of the movable track 51 and the outer wheel 71 according to the width of the carrier belt. Rotate the track screw 61, causing the limiting part 62 to rotate on the fixed track 54. The thread of the track screw 61 pushes the movable track 51 to move, causing it to move along the track guide rod 55 until it corresponds to the scale on the track guide rod 55 corresponding to the width of the carrier belt. Move the outer wheel 71 to the position corresponding to the width of the carrier belt, tighten the bolt in the locking hole 43, and push the positioning groove 47 of the positioning plate 42 into the positioning ring groove 74 to achieve positioning.

[0061] Furthermore, the positions of the lens assembly and illumination assembly 29 are adjusted according to the carrier tape and chip to be processed. Specifically, to achieve a clearer and more accurate image, the position of the lens assembly on the z-axis is adjusted by rotating the adjusting screw 23 to adjust the shooting distance. Based on the chip's location, the positions of the lens assembly on the x-axis and y-axis are adjusted along the first support moving groove and the lens moving groove to obtain the optimal shooting field of view. After determining the lens assembly position, the position of the illumination assembly 29 is adjusted accordingly. The moving limit seat 27 is fixed to the guide rod 25 at a corresponding height using bolts. The positions of the illumination assembly 29 on the x-axis and y-axis are adjusted along the limit groove and the adjusting groove to obtain the optimal illumination effect.

[0062] It should be understood that the above adjustment order is only an example and does not constitute a limitation on the adjustment order in actual use.

[0063] During testing, the two ends of the carrier tape are wound around two carrier tape axles 72, with the side closer to the sensor serving as the feed axle and the side farther from the sensor serving as the take-up axle. The carrier tape moves from the feed axle to the take-up axle, passing through the carrier tape track 5 along the receiving track formed by the first guide protrusion 53 and the second guide protrusion 52, and is further positioned above by the tape pressing plate 56. The drive assembly 75 drives the carrier tape axles 72 to feed and take up the carrier tape according to a preset speed and frequency, realizing automatic counting and detection. At positions corresponding to the first, second, and third through holes, the marking structure 3, image recording structure 2, and sensor can collect information from the carrier tape. The acquired images are processed by the control structure, counted, and judged to determine whether there are quality problems, such as empty packages. For chips with quality problems, the control structure controls the electromagnetic component 31 to demagnetize, the marking slider 34 loses its attraction, and the marking pen 33 slides down the marking guide rail 32, marking the corresponding position on the carrier tape.

[0064] This application provides a counting machine. The counting machine includes a worktable, a carrier tape track, an image recording structure, and a control structure. The carrier tape track and the image recording structure are mounted on the worktable, and the control structure is installed inside the worktable. The control structure is electrically connected to the image recording structure and controls the image recording structure to acquire images from the carrier tape. By acquiring images from the carrier tape through the image recording structure to count and detect chips on the carrier tape track, the counting and quality of chips can be achieved more quickly, reducing manpower consumption and improving production efficiency.

[0065] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
