Description

Technical Field

[0001] This utility model relates to the field of SMT technology, specifically to a material feeding device. Background Technology

[0002] SMT is short for Surface Mount Technology, also known as surface mount technology or surface placement. A pick-and-place machine, also called a placement machine or surface mount system, is a device placed on the PCB pads by moving a placement head after the dispensing machine or screen printer in a production line. Pick-and-place machines use dedicated feeders for feeding components; tape-and-roll feeders are a commonly used type. In existing technologies, conventional pick-and-place machines with tape feeders generally include a tape feeding device, a conveying mechanism, and a waste tape recycling mechanism. The tape feeding device is typically a feeder. The conveying mechanism is located above the head end of the tape feeder and is used to transport the material from the tape feeder to a designated position. The conveying mechanism typically includes a vertical support plate, on which a transmission structure consisting of a cam with a cam groove and a drive rod rotates. The cam is driven by a drive mechanism to rotate around the support plate. The drive rod has three connecting ends: one end is rotatably connected to the support plate, another end is slidably engaged with the cam groove, and the third end is connected to the conveying structure with a suction component, such as a nozzle. The transmission structure drives the conveying structure to move along a horizontal direction (e.g., the X-axis) and a vertical direction (e.g., the Z-axis) to achieve the conveying function. In this type of pick-and-place machine, because one end of the drive rod is rotatably connected to the support plate (i.e., its position relative to the support plate is fixed), the material picking height of the suction component of the conveying structure is also fixed, which greatly limits its applicability. Furthermore, the tape recycling mechanism of this type of chip mounter also suffers from tape jamming, which reduces operability and production efficiency. Improving the material pick-up location and operability during the waste tape recycling process is a significant requirement at the equipment assembly site. Therefore, it is necessary to improve the existing tape feeding equipment, which leads to this invention. Utility Model Content

[0037] Compared with the prior art, the advantages of this utility model are:

[0038] This utility model's material feeding device, through the combination of a height adjustment mechanism and a guide groove on the fixed plate, achieves height adjustment of the conveying structure and the suction nozzle on the conveying structure, thereby enhancing the device's applicability and overcoming the limitation of existing technologies due to fixed suction nozzle heights.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0051] See Figures 1 to 9The tape feeding device of this utility model mainly includes a body 100, a tape feeder 80, a conveying mechanism, and a waste tape recycling mechanism 60. The body 100 is a cuboid frame structure with two layers, a horizontally arranged base 110 in the middle, and side panels (not shown) on all four sides of both the upper and lower layers. The upper side panel has components such as control buttons and a PLC display touchscreen, and the top of the upper layer has components such as an alarm. These structures are conventional existing structures, and their specific structures and working principles are not described, and are not the innovation of this utility model. The upper layer mainly houses the tape feeder 80 and the conveying mechanism, while the lower layer contains electrical components (not shown). The tape feeder 80 is a conventional feeder in existing SMT pick-and-place machines; its specific structure and working principle are not described or limited, and are not the innovation of this utility model. For example... Figure 1 As shown, the tape feeder 80 is disposed in the upper space of the machine body 100 and on the base surface 110, conveying the tape from the rear (side away from the reader) to the front (side facing the reader). The conveying mechanism is disposed on the base surface 110 and located on one side of the tape feeder 80. Figure 1 (Example shown on the left side) Specifically, the conveying mechanism includes a mounting structure 10, a transmission structure 20, a conveying structure 30, a drive structure 40, and a height adjustment mechanism 50. The mounting structure 10 includes a fixed plate 11 extending vertically downwards and fixed to the base surface 110 of the body 100, and one side of the fixed plate 11 that is slidably disposed vertically in the thickness direction. Figure 1 The first movable plate 12 (rear side) is located in the middle. A drive structure 40 is mounted on the first movable plate 12 and includes a drive shaft 41 and a drive reduction motor 42 connected to the drive shaft 41, wherein the drive reduction motor 42 is fixed to the side of the first movable plate 12 facing away from the fixed plate 11. A transmission structure 20 is located on the side of the fixed plate 11 facing away from the first movable plate 12. Figure 1 The front side is shown and connected to the drive shaft 41 on the drive structure 40. To avoid interference with the fixed plate 11 when the first movable plate 12 slides vertically, in this embodiment of the invention, a vertically extending clearance guide groove 111 is provided on the fixed plate 11, and the drive shaft 41 passes through the clearance guide groove 111. The conveying structure 30 is connected to the transmission structure 20 and driven by the transmission structure 20 in the horizontal direction, specifically as shown below. Figure 1The device moves in the left-right and vertical directions as shown. A height adjustment mechanism 50 is installed on the side of the fixed plate 11 facing the first movable plate 12 and drives the first movable plate 12, the drive structure 40, and the transmission structure 20 to move vertically relative to the fixed plate 11 to adjust the height of the conveying structure 30. The conveying structure 30 is equipped with a suction nozzle 33 for picking up and transferring components to be loaded. In other words, by setting the height adjustment mechanism 50 and the clearance guide groove 111 on the fixed plate 11, the height of the conveying structure 30 and the suction nozzle 33 on the conveying structure 30 can be adjusted, thereby making the equipment more versatile and solving the defect in the prior art where the applicability is limited due to the fixed height of the suction nozzle 33. It should be noted that, in this embodiment of the present invention, for ease of description and distinction, the conveying direction of the material belt feeder 80 is also referred to as... Figure 1 The forward and backward directions shown are described as the first direction, which is the horizontal movement direction of the conveying structure 30, i.e. Figure 1 The left and right directions shown are described as the second direction. The first and second directions are perpendicular to each other in the horizontal plane and are both perpendicular to the vertical direction.

[0052] More specifically, such as Figures 2 to 5 As shown, the transmission structure 20 of this utility model includes a cam 21 and a transmission guide rod 22. The cam 21 is connected to the drive shaft 41 and is driven by the drive shaft 41 to rotate around its center (…). Figure 4 The center of cam 21 (marked as O) is the center of rotation. Cam 21 is a wheel with a non-circular outer contour surface, such as... Figure 4 As shown, the cam 21 of this invention has two radially opposite protrusions 222 extending radially outward on its outer contour surface. That is, the distance from any protrusion 222 to the center of the cam 21 is longer than the distance from the other outer contour surfaces to the center of the cam 21, and the distances from the two protrusions 222 to the center of the cam 21 are the same. Preferably, the outer contour surface of any protrusion 222 is provided with rough stripes (not shown). Specifically, the end face of the cam 21 facing away from the fixed plate 11 is as follows... Figure 4 The front side shown has an opening facing the fixing plate 11, that is, as shown Figure 4The cam groove 221 shown is recessed and extended at the rear. The cam groove 221 is formed by concentric and spaced inner groove surfaces (not shown) and outer groove surfaces (not shown). Similarly, the cam groove 221 of this invention is a non-circular groove, meaning it protrudes radially outward at least once. In this embodiment, the cam groove 221 has one radially outward protrusion, and the protruding part at the inner groove surface of the cam groove 221 is exactly outside the center of the cam 21, i.e., the rotation center O. That is, the rotation center of the cam 21 is eccentric to the geometric center (not shown) of the cam groove 221, or the geometric center of the cam groove 221 is eccentric to the rotation center of the cam 21. The transmission guide rod 22 is a non-linear rod, specifically, as shown... Figure 5 As shown, the transmission guide rod 22 of this utility model has three coplanar but non-collinear connecting ends. One connecting end is fixedly connected to the first movable plate 12 via a swing shaft 2240 passing through the clearance guide groove 111 on the fixed plate 11. The swing shaft 2240 and the drive shaft 41 are arranged vertically and parallel to each other in the clearance guide groove 111. That is, the transmission guide rod 22 can deflect and swing relative to the swing shaft 2240. For ease of description and distinction, this connecting end is referred to as the swing connecting end 224. Another connecting end is slidably connected to the cam groove 221 via a sliding shaft (not shown). For ease of description and distinction, this connecting end is referred to as the sliding connecting end 223. A third connecting end is movably connected to the conveying structure 30 via a drive connecting shaft (not shown). Similarly, for ease of description and distinction, this connecting end is referred to as the drive connecting end 225. Further preferably, as Figure 5 As shown in the embodiment of this utility model, the transmission guide rod 22 includes a first guide rod 221 and a second guide rod 222. The first guide rod 221 and the second guide rod 222 have different lengths and are arranged at an angle. The angle is not specifically described or limited, but is an acute angle, such as 30°. The length is also not specifically described or limited. However, to facilitate adjustment of the length of the first guide rod 221 for fine-tuning of the conveying structure 30 in the horizontal and vertical directions, the first guide rod 221 in this embodiment is essentially composed of two movable segments, namely, the first rod segment 2211 and the second rod segment 2212. Therefore, to suppress vibration and noise generated by the adjusted first guide rod 221, the length ratio of the second guide rod 222 to the first guide rod 221 in this embodiment is limited to less than or equal to 1 / 5. That is, no matter how the first rod segment 2211 and the second rod segment 2212 of the first guide rod 221 are adjusted, the length of the second guide rod 222 (…) Figure 5 The length of the first guide rod 221 is indicated by b) Figure 5The ratio of the two guide rods is ≤1 / 5. The upper end of the second guide rod 222 coincides with the top end of the first guide rod 221 (specifically, the first rod segment 2211), and the lower end of the second guide rod 222 extends downward at an angle. The lower end of the second guide rod 222 is implemented as a sliding connection end 223 for connecting to the sliding shaft and slidingly connecting to the cam groove. In this embodiment of the present invention, by limiting the length ratio of the first guide rod 221 and the second guide rod 222, the problem of vibration and noise generated after the length of the first guide rod 221 is solved. In this embodiment of the present invention, the cam 21 is driven by the drive shaft 41 to rotate around its rotation center. Since the sliding connection end 223 of the transmission guide rod 22 is slidably connected to the cam groove on the surface of the cam 21, the transmission guide rod 22 is driven by the cam 21 to reciprocate around the swing connection end 224 on it, thereby driving the conveying structure 30 connected to the drive connection end 225 of the transmission guide rod 22 to reciprocate in the horizontal direction. Furthermore, it should be noted that the number of cams 21 in this embodiment of the present invention is only one, which is more concise than the structure with two cams in the prior art.

[0053] like Figure 2 , Figure 3 and Figure 6 As shown, the conveying structure 30 of this embodiment includes a sliding plate 31, an extension plate 32, and at least two suction nozzles 33. The sliding plate 31 extends horizontally along a second direction, i.e., as shown... Figure 6 The sliding plate 31 extends to the right and is movably connected to the drive connection end 225 of the transmission guide rod 22. The sliding plate 31 is slidably connected to the fixed plate 11 via a first slide rail 34 extending vertically and a second slide rail 35 extending horizontally in the second direction. Specifically, the two first slide rails 34 are fixed to the side of the fixed plate 11 facing away from the first movable plate 12, opposite each other and spaced apart in the second direction and extending vertically. To facilitate the installation of the second slide rail 35, as shown... Figure 3 As shown, a second movable plate 13 is slidably connected to the first slide rail 34. At least two sliders are fixed to the side of the second movable plate 13 extending in the second direction and facing away from the fixed plate 11, spaced apart along the second direction. The second slide rail 35 is fixed to the side of the sliding plate 31 facing the fixed plate 11. The sliding plate 31 is actually composed of... Figure 3 or Figure 6 The two parts shown are separated, forming a movable gap for the drive connection end 225 to be movably connected. Furthermore, as... Figure 3As shown, a contact roller 131 is provided at the top of the middle position of the second movable plate 13, which rolls in contact with the outer contour surface of the cam 21. In order to ensure that the contact roller 131 is always in contact with the cam 21, so that the sliding plate 31 can move horizontally in the second direction and vertically in the vertical direction through the rotational motion of the cam 21, the second movable plate 13 and the first movable plate 12 are connected by a vertically arranged elastic connector 14, such as a tubular straight spring. The elastic connector 14 applies a biasing force to the second movable plate 13 so that the contact roller 131 on the second movable plate 13 is always in contact with the outer contour surface of the cam 21. Of course, since the first movable plate 12 and the second movable plate are located on the two sides of the fixed plate 11, the upper end of the elastic connector 14 can be connected to a horizontal connecting plate (not shown) fixed to the side of the first movable plate 12. Similarly, a horizontal connecting plate (not shown) can also be provided on the side of the second movable plate 13, and the lower end of the elastic connector 14 is connected to the horizontal connecting plate fixed to the side of the second movable plate 13. When cam 21 rotates, the contact roller 131 contacts the protrusion 222 on cam 21, causing the second movable plate 13 to drive the sliding plate 31 of the conveying structure 30 to move downwards in the vertical direction. This causes the suction nozzle 33 on the conveying structure 30 to move downwards, allowing it to pick up components at the loading station and place components at the transfer platform 70 or unloading station. After the contact roller 131 passes the protrusion 222 on cam 21, the second movable plate 13 returns to its original position upwards under the action of the elastic connector 14, causing the suction nozzle 33 on the conveying structure 30 to move upwards away from the loading station, transfer platform 70, or unloading station. The horizontal movement of the sliding plate 31 or the conveying structure 30 is achieved by the horizontal component force of the swinging transmission guide rod 22, specifically in the second direction. In this embodiment of the invention, an extension plate 32 is provided at the end of the sliding plate 31 away from the end connected to the transmission guide rod 22. The extension plate 32 extends along a second direction, and at least two suction nozzles 33 are spaced apart on the extension plate 32 along the extension direction of the extension plate 32, i.e., the second direction. To achieve temporary storage of components, shorten the moving distance between loading and unloading, and improve efficiency, in this embodiment of the invention, on the base surface 110, on the other side of the material feeder 80, i.e., the side opposite to the fixed plate 11, i.e., as shown... Figure 2 and Figure 6The right side shown has at least one transfer platform 70, on which components can be temporarily stored, thereby shortening the transfer distance between loading and unloading and improving efficiency. In this way, one suction nozzle 33, specifically the one near the feeder 80, can pick up components at the loading station (i.e., the end of the feeder 80) for loading and temporary storage, while the other suction nozzle 33, the one farther from the feeder 80, corresponds to the transfer platform 70 for temporary storage and unloading. That is, the suction nozzle 33 near the feeder 80 can switch back and forth between the loading station and the temporary storage station or the transfer platform 70, while the suction nozzle 33 farther from the feeder 80 can switch back and forth between the temporary storage station or the transfer platform 70 and the unloading station. This improves the conveying efficiency of the conveying structure 30. Each transfer platform 70 has a vacuum adsorption hole (not shown) to facilitate the adsorption and fixation of components and the insertion of the suction nozzle 33. Preferably, as Figure 6 As shown, in this embodiment of the invention, there are three suction nozzles 33 and two corresponding transfer platforms 70. The suction nozzle 33 closest to the feeder 80 switches back and forth between the loading station and the transfer platform 70 on the side closest to the feeder 80. The middle suction nozzle 33 switches back and forth between the two transfer platforms 70, while the suction nozzle 33 furthest from the feeder 80 switches back and forth between the transfer platform 70 furthest from the feeder 80 and the unloading station. In this embodiment, the suction nozzles 33 are fixed by needle clamps (not shown). To ensure that the suction nozzles 33 correspond to the vacuum suction holes on the corresponding transfer platforms 70 and improve adjustment efficiency, as shown... Figure 6As shown, a sensor 75 is provided at each of the two transfer platforms 70, with the light emitting end of each sensor 75 facing downwards. The transfer platform 70 is also mounted on an adjustment plate 73. By adjusting the position of the adjustment plate 73 on the base surface 110, the light emitting end of the sensor 75 is aligned with the suction nozzle 33 and the vacuum adsorption hole on the transfer platform 70, i.e., on the same vertical line. This adjustment is simple and convenient, improving adjustment efficiency. Specifically, the base surface 110 is provided with an adjustment plate 73 that can be moved and adjusted along the extension direction of the extension plate 32, i.e., the second direction. Above the adjustment plate 73, two vertically extending supports 72 are spaced apart. Above the two supports 72, a platform plate 71 is provided that is horizontally arranged and extends along the second direction. The two transfer platforms 70 are spaced apart on the platform plate 71. A fixing frame 74 is provided on the side of the platform plate 71 corresponding to the positions of the two transfer platforms 70. Each fixing frame 74 has a sensor 75 with its light-emitting end facing downwards (this is a conventional photoelectric sensor 75; its specific structure and working principle are not described or limited, as it is existing technology and not an innovation of this utility model). By adjusting the position of the adjusting plate 73, during the reciprocating translation of the extension plate 32 driven by the sliding plate 31, any two adjacent suction nozzles 33 correspond to the centers of the vacuum adsorption holes of the two transfer platforms 70, specifically, the suction nozzles 33 can be inserted into the vacuum adsorption holes. In other words, rapid adjustment is achieved by aligning the sensor 75, the suction nozzles 33, and the vacuum adsorption holes on the transfer platform 70 with the same straight line, i.e., collinearity, thus improving adjustment efficiency. For the adjusting plate 73, in order to adjust its position relative to the base surface 110, the adjusting plate 73 has multiple (specifically not limited, but exemplarily six, such as three arranged in a triangular shape at each end) elongated slot-shaped adjusting holes extending along the second direction. The base surface 110 has circular holes (not shown). Preferably, there are two adjusting plates 73 stacked one above the other, with the lower one being longer. The upper adjusting plate 73 has adjusting holes along the second direction (described here as first adjusting holes 731 for easy distinction), and the lower adjusting plate 73 has adjusting holes along the first direction (described here as second adjusting holes 732 for easy distinction).

[0054] Preferably, in order to simplify assembly and adjustment operations, shorten adjustment time, and improve accuracy, such as Figure 1 As shown, a reference surface 120 is provided on the base surface 110, which is exemplarily a reference groove in the shape of a cross or a T provided on the side of the adjustment plate 73.

[0055] like Figure 1 As shown, in this embodiment of the utility model, the material strip recycling mechanism is located on the side panel of the machine body 100 and corresponds to the tail end of the material strip feeder 80, i.e. Figure 1 The front side shown. Specifically, as... Figures 7 to 9As shown, the system includes a first recycling track 61, a tape-cutting and recycling mechanism 62, a second recycling track 63, and a recycling box 64. The first recycling track 61 extends vertically and tapers from top to bottom. Its upper end, facing the tape feeder 80 (i.e., its inner side), has a tape inlet 611, and its lower end, the bottom end, has a first tape outlet. After the components on the tape are sucked up by the suction nozzle 33 at the tail end of the tape feeder 80 (i.e., the loading station) and transferred to the transfer platform 70, the waste tape flows down through the tape inlet 611 of the first recycling track 61 to the first tape outlet. The tape-cutting and recycling mechanism 62 is located below the first tape outlet. To prevent excessive tape from tangling and failing to fall smoothly into the recycling box 64 at the bottom, the tape-cutting and recycling mechanism 62 is a single-sided... Figure 9 The front-opening, hollow, roughly square shell shown has a receiving hopper 621 at the top of the tape-cutting and recycling mechanism 62, and a discharge hopper 622 below the receiving hopper 621. A waste tape cutting mechanism, which can be opened and closed to perform cutting actions, is located in the gap between the discharge hopper 622 and the receiving hopper 621. A second recycling track 63 is located below the discharge hopper 622 of the tape-cutting and recycling mechanism 62 and extends vertically, widening from top to bottom. The bottom of the second recycling track 63 has a second tape outlet, facilitating the smooth fall of the cut waste tape into the recycling box 64 at the bottom. The recycling box 64 is movably disposed at the bottom of the machine body 100 and communicates with the second tape outlet. For example, a support plate (not shown) can be provided at the bottom of the machine body 100, allowing the recycling box 64 to be pushed, pulled, and slidably placed on the support plate, facilitating the removal of the recycling box 64 to empty the waste tape and preventing the waste tape from piling up in the recycling box 64. In this embodiment of the invention, to prevent the front end of the conveyor belt from getting stuck on the first recycling track 61 at the cut-off point, as follows: Figure 8As shown, at the outlet end of the receiving hopper 621, there are two oppositely arranged first sidewalls 6211 and second sidewalls 6212 that extend vertically downwards respectively. The downward extension length of the first sidewall 6211 is greater than the downward extension length of the second sidewall 6212. A spring plate 65 is provided on the first sidewall 6211, which is curved toward the second sidewall 6212. A clearance gap is formed between the spring plate 65 and the second sidewall 6212 to allow the waste belt to pass through. When the waste belt passes through the clearance gap, the spring plate 65 is adapted to elastically press against the waste belt. The waste belt cutting mechanism is located below the first sidewall 6211 and the second sidewall 6212. That is, after the waste belt cutting mechanism cuts the waste belt, the spring plate 65 presses against the front end of the waste belt. Thus, the spring plate 65 can alleviate the stress on the waste strip during cutting. Regardless of the degree of curling of the waste strip, the front end of the cut strip can always be kept on the same recycling track surface by the spring plate 65, thereby preventing the front end of the strip from getting stuck on the first recycling track 61 at the cut point. At the same time, when changing the feeder, i.e., the strip feeder 80, and pulling out the strip, the arc shape of the spring plate 65 can also prevent the front end of the strip from getting stuck on the spring plate 65. As for the spring plate 65, it is exemplarily a hook-shaped structure, with its upper end fixed to the upper end of the receiving hopper 621 and its lower end contacting the outer surface of the first side wall 6211. For the waste strip cutting mechanism, conventional pneumatic shears can be selected. For the strip cutting and recycling mechanism 62, it can be a square box with one side open, hollow inside, and an inverted cone-shaped hopper 622 on the bottom surface, with the opening for the waste strip cutting mechanism to extend into and cut the waste strip.

[0056] like Figure 2 As shown, the height adjustment mechanism 50 of this embodiment includes a lifting drive motor 51, a third slide rail 52, and a third slider 53. The lifting drive motor 51 is fixed to the fixing plate 11 via a motor base, and the driving end of the lifting drive motor 51 is vertical and downwards. Two third slide rails 52 are provided and are arranged vertically... Figure 2 The three slides are arranged in a vertical direction and fixed to the side of the fixed plate 11 facing the first movable plate 12. The first movable plate 12 is slidably connected to the third slide rail 52 via the third slider 53. The drive end of the lifting drive motor 51 (e.g., via a transmission belt and a transmission wheel) is connected to a lifting drive screw 54 extending vertically upward. The lifting drive screw 54 is movably connected to a screw nut (not shown) located at the bottom of the first movable plate 12. To facilitate the lifting drive screw 54 interfering with the bottom surface of the first movable plate 12 during height adjustment, a clearance groove (not shown) is provided on the bottom surface of the first movable plate 12, and the screw nut is located in the clearance groove.
