Description

Technical Field

[0001] This utility model relates to the field of electronic component shaping device technology, and in particular to an online lead shaping machine. Background Technology

[0002] Electronic components typically include transformers, inductors, and resistors. The leads of these components usually extend to the outside of the component body. To facilitate component installation, the leads need to be shaped, such as shaping multiple leads into straight or L-shaped leads. Lead straightening machines need to shape the horizontal ends of all L-shaped leads to a flush (coplanar) state. Currently, most lead straightening machines use fixtures to position electronic components. These fixtures move between the loading / unloading station and the lead straightening station. The loading / unloading station typically uses manual methods to feed electronic components to the fixture, which then positions the components at the lead straightening station for lead straightening. This results in low lead straightening efficiency, high labor costs, and an inability to adapt to automated electronic component production. Utility Model Content

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figure 1This utility model discloses an online foot straightening machine, including a frame 2 and a feeding conveyor belt 4, a discharging conveyor belt 5, a handling device 6, and two foot straightening devices 3, all mounted on the frame 2. The frame 2 is provided with a fixture 21 for positioning an electronic component 1. The electronic component 1 includes a main body and multiple L-shaped pins disposed on the main body. The multiple pins are located on the front and rear sides of the main body. When the electronic component 1 is positioned on the fixture 21, the multiple pins of the electronic component 1 extend to the front and rear sides of the fixture 21 respectively. (Refer to...) Figures 1 to 3 Two foot-aligning devices 3 are respectively located on the front and rear sides of the fixture 21. Each foot-aligning device 3 includes a foot-aligning gripper 31 that can move in the front-back and up-down directions. The two foot-aligning grippers 31 are respectively configured to clamp the pins extending to the front and rear sides of the fixture 21 so that the horizontal ends of all pins are aligned. The loading conveyor belt 4 and the unloading conveyor belt 5 are respectively located on the left and right sides of the fixture 21. (Refer to...) Figure 1 and Figure 4 The conveying device 6 includes a loading gripper 61 and a unloading gripper 62 that can move synchronously in the left-right and up-down directions. The loading gripper 61 is configured to transport the electronic component 1 at the output end of the loading conveyor belt 4 to the fixture 21, and the unloading gripper 62 is configured to transport the electronic component 1 on the fixture 21 to the input end of the unloading conveyor belt 5.

[0021] The feeding conveyor belt 4 is used to feed electronic components 1 that are to be processed. The electronic components 1 can be manually transported to the input end of the feeding conveyor belt 4, or it can be connected to an automated production equipment for electronic components. The automated production equipment for electronic components will transport the electronic components 1 to the input end of the feeding conveyor belt 4, and the electronic components 1 to be processed will be transported from the input end of the feeding conveyor belt 4 to the output end of the feeding conveyor belt 4.Initially, the loading gripper 61 moves to the position corresponding to the output end of the loading conveyor belt 4, gripping the electronic component 1 on the output end of the loading conveyor belt 4. At this time, the unloading gripper 62 moves to the position corresponding to the fixture 21. Then, the conveying device 6 drives the loading gripper 61 and the unloading gripper 62 to move synchronously upward and to the right, respectively, above the fixture 21 and above the input end of the unloading conveyor belt 5. Then, the loading gripper 61 and the unloading gripper 62 descend synchronously. The loading gripper 61 moves to the position corresponding to the fixture 21 and places the electronic component 1 to be processed on the fixture 21. At this time, the unloading gripper 62 moves to the position corresponding to the input end of the unloading conveyor belt 5, and the two processed components are then placed on the fixture 21. The two clamping jaws 31 of fixture 3 respectively clamp the pins extending to the front and rear sides of fixture 21, making the horizontal ends of all pins flush, thus completing the pin alignment of electronic component 1. This ensures that when electronic component 1 is mounted on a carrier such as a circuit board, the horizontal ends of all pins abut against the contacts or solder joints on the same plane of the carrier. Next, the conveying device 6 drives the loading jaw 61 and unloading jaw 62 to move synchronously upward and to the left. Immediately afterwards, the loading jaw 61 and unloading jaw 62 descend synchronously. The loading jaw 61 moves to the position corresponding to the output end of the loading conveyor belt 4, clamping another electronic component 1 on the output end of the loading conveyor belt 4. At this time, the unloading jaw 62 moves to the position corresponding to fixture 21. 2. The clamping fixture 21 holds the pre-formed electronic component 1; then the conveying device 6 drives the loading jaw 61 and unloading jaw 62 to move synchronously upwards and to the right. The loading jaw 61 and unloading jaw 62 move to the top of the fixture 21 and the top of the input end of the unloading conveyor belt 5, respectively. Then, the loading jaw 61 and unloading jaw 62 descend synchronously. The loading jaw 61 moves to the position corresponding to the fixture 21 and places the other electronic component 1 to be formed on the fixture 21. The unloading jaw 62 moves to the position corresponding to the input end of the unloading conveyor belt 5 and places the pre-formed electronic component 1 on the input end of the unloading conveyor belt 5. The unloading conveyor belt 5 is used to transport the pre-formed electronic component 1 from the input end of the unloading conveyor belt 5 to the bottom. The output end of the material conveyor belt 5 can be manually removed from the electronic component 1, or the output end of the material conveyor belt 5 can be connected to the automated production equipment for electronic components. The material conveyor belt 5 transports the finished electronic component 1 to the automated production equipment for electronic components. In this way, the finishing of electronic components 1 can be continuously completed. The loading gripper 61 and unloading gripper 62 of the conveying device 6 load the electronic component 1 to be finished and unload the finished electronic component 1 to the fixture 21, ensuring the accuracy of the electronic component 1 to be finished on the fixture 21. The loading and unloading efficiency of electronic components 1 is high, thereby effectively improving the finishing efficiency, reducing the workload of manual laborers, and reducing labor costs.

[0022] The feeding conveyor belt 4 is oriented left-right, with its input and output ends distributed along this direction. Similarly, the unloading conveyor belt 5 is oriented left-right, with its input and output ends distributed along this direction. Of course, the feeding directions of the feeding and unloading conveyor belts 4 and 5 can be set according to actual conditions. For example, the feeding directions of the feeding and unloading conveyor belts 4 and 5 can be parallel to the front-back direction, ensuring that the output end of the feeding conveyor belt 4 is close to fixture 21 and the input end of the unloading conveyor belt 5 is close to fixture 21. The two leg-aligning devices 3 have identical or similar structures and are symmetrically distributed front-back with the left-right direction as their center line.

[0023] In this embodiment, the electronic component 1 is a transformer. The transformer has a total of ten pins, five of which are located on the front side of the transformer body and the other five are located on the rear side of the transformer body. The full-leg gripper 31 located in front of the fixture 21 grips the five pins on the front side of the transformer body, and the full-leg gripper 31 located behind the fixture 21 grips the five pins on the rear side of the transformer body.

[0024] Reference Figure 2 and Figure 5 In some embodiments, the jig 21 is plate-shaped, with a front side and a rear side. The thickness of the jig 21 gradually decreases from bottom to top in the front-rear direction, with the upper end of the jig 21 having a smaller thickness in the front-rear direction. This avoids interference between the upper end of the jig 21 and the clamping jaw 31, increases the movement range of the clamping jaw 31, and ensures that the clamping jaw 31 can simultaneously hold multiple pins and align them on the same plane. The lower end of the jig 21 is connected to the frame 2 via a first fastener, and the lower end of the jig 21 has a larger thickness in the front-rear direction to ensure the stability of the jig 21 on the frame 2 and to ensure the load-bearing capacity of the jig 21. Of course, the jig 21 can also be cylindrical or conical.

[0025] The fixture 21 has a support extending in the left-right direction. A limiting groove 211 is formed on the upper surface of the support. The limiting groove 211 penetrates the front and rear sides of the support. The left and right inner walls of the limiting groove 211 are respectively configured to abut against the left and right sides of the electronic component 1. The depth of the limiting groove 211 is less than the height of the electronic component 1. When the loading gripper 61 places the electronic component 1 to be aligned in the limiting groove 211, multiple pins of the electronic component 1 extend to the front and rear sides of the fixture 21. The left and right sides of the electronic component 1 abut against the left and right inner walls of the limiting groove 211, and the top of the electronic component 1 is higher than the upper surface of the support. The part of the electronic component 1 that is higher than the upper surface of the support can be clamped by the loading gripper 61 or the unloading gripper 62. The part of the electronic component 1 that is higher than the upper surface of the support can also be clamped by other external equipment or used by other external equipment to perform positioning operations on the electronic component 1.

[0026] It is understandable that the loading gripper 61 or unloading gripper 62 has the same structure. The loading gripper 61 includes a clamping cylinder and two gripping arms respectively disposed at the two output ends of the clamping cylinder. The clamping cylinder drives the two gripping arms to move closer or further apart, so that the two gripping arms clamp or release the electronic component 1. The two gripping arms are distributed front and back. Since the limiting groove 211 passes through the front and back sides of the support, when the two gripping arms clamp the front and back sides of the electronic component 1 and drive the electronic component 1 into the limiting groove 211, the two gripping arms will not interfere with the support. Of course, the two gripping arms can also only clamp the part of the electronic component 1 that is higher than the upper surface of the support. The loading gripper 61 or unloading gripper 62 can also use commonly available components on the market. The loading gripper 61 or unloading gripper 62 can also be replaced with a suction nozzle.

[0027] The dimension of the limiting groove 211 in the left-right direction is greater than or equal to the dimension of the electronic component 1 in the left-right direction, and the thickness of the support in the front-back direction is equal to the width of the electronic component 1 in the front-back direction. When the electronic component 1 is placed in the limiting groove 211, only the pins extend outside the fixture 21 in the front-back direction, thus preventing the full-foot gripper 31 from accidentally gripping the non-pin structure of the electronic component 1.

[0028] Reference Figure 1 and Figure 2 In some embodiments, the foot straightening machine further includes a pressing device 7, which includes a pressing member 71 that can move in the horizontal and vertical directions. The pressing member 71 is not directly above the fixture 21 to avoid interference between the pressing member 71 and the loading gripper 61 and the unloading gripper 62. This allows the loading gripper 61 to smoothly place the electronic component 1 to be straightened on the fixture 21, and allows the unloading gripper 62 to smoothly remove the straightened electronic component 1 from the fixture 21.

[0029] Initially, the pressing member 71 is not directly above the fixture 21, and its position is higher than the fixture 21. After the loading gripper 61 successfully places the electronic component 1 to be aligned onto the fixture 21, the pressing member 71 moves upward and downward directly above the electronic component 1 on the fixture 21, pressing against the top of the electronic component 1. This positions the electronic component 1 on the fixture 21, ensuring its stability and preventing it from shifting or falling off. When the pins are lowered, the two pin-shaping jaws 31 can grip the pins extending to the front and rear sides of the fixture 21, ensuring that the two pin-shaping jaws 31 accurately grip the pins and shape them, thereby ensuring the efficiency and quality of pin shaping. After the pin shaping of electronic component 1 is completed, electronic component 1 moves up and shifts away from the top of electronic component 1, so that the unloading jaws 62 can smoothly remove the pin-shaping electronic component 1 from the fixture 21, and the loading jaws 61 can smoothly place another electronic component 1 to be pin-shaping onto the fixture 21.

[0030] Reference Figure 2 In some embodiments, the pressing device 7 further includes a rotary cylinder 72 disposed on the frame 2. The rotary cylinder 72 is disposed on one side of the fixture 21 to avoid the rotary cylinder 72 affecting the movement path of the loading gripper 61 and the unloading gripper 62. The output end of the rotary cylinder 72 faces upward and is connected to a swing arm 73. The rotary cylinder 72 can drive the swing arm 73 to rotate on the horizontal plane with the vertical or up-down direction as the rotation center line. The rotary cylinder 72 can also drive the swing arm 73 to rise and fall in the vertical or up-down direction. The free end of the swing arm 73 is threadedly connected to the upper end of the lower pressure member 71. The free end of the swing arm 73 drives the lower pressure member 71 to move, so that the lower pressure member 71 can press the electronic component 1 down onto the fixture 21, and the lower pressure member 71 avoids the area directly above the fixture 21, so that the unloading chuck 62 can smoothly remove the already trimmed electronic component 1 from the fixture 21, and the loading chuck 61 can smoothly place another electronic component 1 to be trimmed onto the fixture 21.

[0031] In another embodiment, the rotary cylinder 72 can be replaced by a first linear drive mechanism and a second linear drive mechanism. The first linear drive mechanism and the second linear drive mechanism drive the pressing member 71 to move above the fixture 21 and to move in the vertical direction, respectively. Both the first linear drive mechanism and the second linear drive mechanism can be a lead screw moving pair, a cylinder, or an electric actuator.

[0032] Reference Figure 2In some embodiments, the foot-shaping device 3 includes a first lifting drive mechanism 32 and a front-to-back linear drive mechanism 33. The first lifting drive mechanism 32 and the front-to-back linear drive mechanism 33 are used to drive the foot-shaping gripper 31 to lift and move in the front-to-back direction, respectively. Before the electronic component 1 to be shaped is placed on the fixture 21, the first lifting drive mechanism 32 and the front-to-back linear drive mechanism 33 drive the foot-shaping gripper 31 away from the fixture 21, so that when the loading gripper 61 places the electronic component 1 to be shaped on the fixture 21, the multiple pins of the electronic component 1 can extend smoothly to the front and back sides of the fixture 21. After the electronic component 1 is placed on the fixture 21, the first lifting drive mechanism 32 and the front-to-back linear drive mechanism 33 drive the foot-shaping gripper 31 to approach the electronic component 1 to be shaped on the fixture 21, so that the foot-shaping gripper 31 can accurately clamp the pins of the electronic component 1 and pull the pins of the electronic component 1 to complete the pin shaping, that is, to complete the foot shaping.

[0033] In one embodiment of the foot-aligning device 3, a first lifting drive mechanism 32 is connected to the frame 2. The output end of the first lifting drive mechanism 32 is connected to a front and rear linear drive mechanism 33, and the output end of the front and rear linear drive mechanism 33 is connected to the foot-aligning gripper 31. The first lifting drive mechanism 32 can drive the front and rear linear drive mechanism 33 and the foot-aligning gripper 31 to rise and fall. The front and rear linear drive mechanism 33 can drive the foot-aligning gripper 31 to move in the front and rear direction, that is, drive the foot-aligning gripper 31 to move closer to or away from the fixture 21. It is conceivable that the frame 2 is provided with a table, and the table is provided with a clearance hole communicating with the inner cavity of the frame 2. The first lifting drive mechanism 32 is located in the inner cavity of the frame 2. The output end of the first lifting drive mechanism 32 is connected to the front and rear linear drive mechanism 33 through a lifting plate. The lifting plate passes through the clearance hole, and the upper end of the lifting plate extends above the table and is connected to the front and rear linear drive mechanism 33.

[0034] In another embodiment of the foot straightening device 3, the front and rear linear drive mechanism 33 is connected to the frame 2, the output end of the front and rear linear drive mechanism 33 is connected to the first lifting drive mechanism 32, the output end of the first lifting drive mechanism 32 is connected to the foot straightening gripper 31, the front and rear linear drive mechanism 33 can drive the first lifting drive mechanism 32 and the foot straightening gripper 31 to move in the front and rear direction, and the first lifting drive mechanism 32 can drive the foot straightening gripper 31 to rise and fall.

[0035] Reference Figure 2 and Figure 3In some embodiments, the foot gripper 31 includes a stationary gripper 311, a second lifting drive mechanism 312, and a movable gripper 313. The second lifting drive mechanism 312 is mounted on the stationary gripper 311, and its output end is connected to the movable gripper 313. The second lifting drive mechanism 312 drives the movable gripper 313 to move up and down, allowing it to move closer to or away from the stationary gripper 311, so that the movable gripper 313 and the stationary gripper 311 can grip the pins extending to the front or rear side of the fixture 21. The second lifting drive mechanism 312 drives the opening and closing of the stationary gripper 311 and the movable gripper 313. The stationary gripper 311 is connected to the output end of the front and rear linear drive mechanism 33 or the first lifting drive mechanism 32.

[0036] The stationary clamping block 311 has a horizontal stationary clamping surface, and the movable clamping block 313 has a horizontal movable clamping surface. Initially, the movable clamping block 313 is away from the stationary clamping block 311. The first lifting drive mechanism 32 and the front and rear linear drive mechanism 33 drive the stationary clamping block 311, the second lifting drive mechanism 312 and the movable clamping block 313 to move synchronously, so that the horizontal ends of multiple pins extending outside the fixture 21 are all between the movable clamping block 313 and the stationary clamping block 311. Then, the second lifting drive mechanism 312 drives the movable clamping block 313 to move closer to the stationary clamping block 311. The stationary clamping surface of the stationary clamping block 311 and the movable clamping surface of the movable clamping block 313 clamp the horizontal ends of multiple pins, so that the horizontal ends of multiple pins are aligned.

[0037] It is understandable that the first lifting drive mechanism 32 and the front and rear linear drive mechanism 33 first drive the stationary clamping block 311, the second lifting drive mechanism 312, and the moving clamping block 313 to move synchronously to a fixed position, so that the horizontal ends of the multiple pins extending outside the fixture 21 are all between the moving clamping block 313 and the stationary clamping block 311. Then, the second lifting drive mechanism 312 drives the moving clamping block 313 to move closer to the stationary clamping block 311, so that the moving clamping block 313 and the stationary clamping block 311 can clamp the horizontal ends of the multiple pins, thereby making the horizontal ends of the multiple pins flush; or the first lifting drive mechanism 32 and the front and rear linear drive mechanism 33 first drive the stationary clamping block 311 to move synchronously to a fixed position, so that the horizontal ends of the multiple pins are all between the moving clamping block 313 and the stationary clamping block 311. Mechanism 33 first drives the stationary clamping block 311, the second lifting drive mechanism 312, and the moving clamping block 313 to move synchronously to a fixed position, so that the horizontal ends of multiple pins extending outside the fixture 21 are all between the moving clamping block 313 and the stationary clamping block 311. Then, the second lifting drive mechanism 312 drives the moving clamping block 313 to move closer to the stationary clamping block 311, and the first lifting drive mechanism 32 simultaneously drives the stationary clamping block 311, the second lifting drive mechanism 312, and the moving clamping block 313 to rise and fall, so that the moving clamping block 313 and the stationary clamping block 311 can clamp the horizontal ends of multiple pins, thereby making the horizontal ends of multiple pins flush.

[0038] In this embodiment, the first lifting drive mechanism 32 is connected to the frame 2, the output end of the first lifting drive mechanism 32 is connected to the front and rear linear drive mechanism 33, the output end of the front and rear linear drive mechanism 33 is connected to the stationary clamping block 311, the movable clamping block 313 is located above the stationary clamping block 311, the second lifting drive mechanism 312 is located on the stationary clamping block 311, and the output end of the second lifting drive mechanism 312 is connected to the movable clamping block 313.

[0039] Reference Figure 4 In some embodiments, the conveying device 6 includes a left-right drive mechanism 63 and a third lifting drive mechanism 64. The distance between the loading gripper 61 and the unloading gripper 62 is equal to the distance between the output end of the loading conveyor belt 4 and the fixture 21, and the distance between the fixture 21 and the input end of the unloading conveyor belt 5. The left-right drive mechanism 63 is used to drive the loading gripper 61 and the unloading gripper 62 to move in the left-right direction, so that the loading gripper 61 moves between the output end of the loading conveyor belt 4 and the fixture 21, and the unloading gripper 62 moves between the fixture 21 and the input end of the unloading conveyor belt 5. The third lifting drive mechanism 64 is used to drive the loading gripper 61 and the unloading gripper 62 to lift synchronously, which can ensure that the loading gripper 61 and the unloading gripper 62 correspond to the output end of the loading conveyor belt 4 and the fixture 21 respectively, or the loading gripper 61 and the unloading gripper 62 correspond to the fixture 21 and the input end of the unloading conveyor belt 5 respectively.

[0040] In some embodiments, the conveying device 6 further includes a first bracket 65 disposed on the frame 2, a left and right drive mechanism 63 disposed on the first bracket 65, the output end of the left and right drive mechanism 63 being connected to a third lifting drive mechanism 64, the output end of the third lifting drive mechanism 64 being connected to a connecting plate 66, and the loading gripper 61 and the unloading gripper 62 being disposed at the left and right ends of the connecting plate 66 respectively. The first bracket 65 supports the left and right drive mechanisms 63, the third lifting drive mechanism 64, the connecting plate 66, the loading gripper 61, and the unloading gripper 62 on the frame 2. The left and right drive mechanisms 63 and the third lifting drive mechanism 64 drive the loading gripper 61 to move between the output end of the loading conveyor belt 4 and the fixture 21 to transport the electronic component 1 from the output end of the loading conveyor belt 4 to the fixture 21. The left and right drive mechanisms 63 and the third lifting drive mechanism 64 also simultaneously drive the unloading gripper 62 to move between the fixture 21 and the input end of the unloading conveyor belt 5 to transport the electronic component 1 on the fixture 21 to the input end of the unloading conveyor belt 5.

[0041] In another embodiment, the conveying device 6 further includes a first bracket 65 disposed on the frame 2, a third lifting drive mechanism 64 disposed on the first bracket 65, the output end of the third lifting drive mechanism 64 being connected to the left and right drive mechanisms 63, the output end of the left and right drive mechanisms 63 being connected to a connecting plate 66, and the loading gripper 61 and the unloading gripper 62 being disposed at the left and right ends of the connecting plate 66 respectively.

[0042] Reference Figure 1 and Figure 6 In some embodiments, the feeding conveyor belt 4 includes a second support 41, a rotary drive mechanism 48, a belt 42, and a drive pulley 43 and a driven pulley 44 both mounted on the second support 41. The drive pulley 43 and the driven pulley 44 extend axially in the front-back direction. The belt 42 is wound around the drive pulley 43 and the driven pulley 44. The output end of the rotary drive mechanism 48 is connected to the drive pulley 43 for transmission. The rotary drive mechanism 48 drives the drive pulley 43 to rotate, thereby driving the belt 42 to rotate and placing the electronic component 1 on the belt 42, thus conveying the electronic component 1 from the input end of the feeding conveyor belt 4 to the output end of the feeding conveyor belt 4.

[0043] The second support 41 is equipped with a positioning block 45 and a positioning sensor 46 in the area near the fixture 21. The positioning block 45 serves to block and stop the electronic component 1, and the positioning sensor 46 is used to detect whether the positioning block 45 is blocking the electronic component 1. When the positioning sensor 46 detects that the positioning block 45 is blocking the electronic component 1, the feeding gripper 61 can transport the electronic component 1 that is blocked by the positioning block 45 on the output end of the feeding conveyor belt 4 to the fixture 21.

[0044] It should be noted that the second support 41 includes several support rods and a support plate mounted on the support rods. The lower ends of the support rods are connected to the frame 2. The length of the support plate extends in the left-right direction. The feeding conveyor belt 4 also includes two first mounting plates 411 and two second mounting plates 412. Each of the two first mounting plates 411 has a first oblong hole at one end. The length of the two first oblong holes extends in the up-down direction. The axial direction of the two first oblong holes is in the front-back direction, and the two first oblong holes are coaxially arranged. Two second fasteners pass through the two first oblong holes and are connected to one end of the support plate, thereby connecting one end of the two first mounting plates 411 to one end of the support plate. The rotary drive mechanism 48 is connected to the other end of one of the first mounting plates 411. The output end is connected to the drive pulley 43; similarly, each of the two second mounting plates 412 has a second waist-shaped hole at one end. The length of the two second waist-shaped holes extends in the vertical direction, and the axial direction of the two second waist-shaped holes is in the front-back direction. The two second waist-shaped holes are coaxially arranged. Two third fasteners pass through the two second waist-shaped holes and are connected to the other end of the support plate, so that one end of the two second mounting plates 412 is connected to the other end of the support plate. The driven pulley 44 is rotatably connected to the other end of the two second mounting plates 412. The height of the drive pulley 43 and the driven pulley 44 relative to the support plate can be adjusted through the two first mounting plates 411, the two second mounting plates 412, the two second fasteners and the two third fasteners, so that the belt 42 can rotate smoothly and transport the electronic component 1.

[0045] On the second bracket 41, near the fixture 21, at the other end of the support plate, the positioning block 45 and the positioning sensor 46 are located on the other end of the support plate.

[0046] Reference Figure 6 In some embodiments, guide baffles 47 are provided on both the front and rear sides of the second bracket 41. Both guide baffles 47 are located above the belt 42. A guide channel is formed between the two guide baffles 47 for a number of electronic components 1 to pass through in a row. The two guide baffles 47 serve to guide and limit the electronic components 1, ensuring that the electronic components 1 on the belt 42 move toward the positioning block 45, preventing the electronic components 1 from shifting on the belt 42 or accidentally falling off the belt 42, so that the feeding gripper 61 can accurately clamp the electronic components 1 at a fixed position at the output end of the feeding conveyor belt 4.

[0047] The structure of the unloading conveyor belt 5 is the same as or similar to that of the loading conveyor belt 4, and will not be described redundantly here.

[0048] The first lifting drive mechanism 32, the front and rear linear drive mechanism 33, the second lifting drive mechanism 312, the left and right drive mechanism 63, and the third lifting drive mechanism 64 can all be lead screw moving pairs, cylinders, or electric actuators. The rotary drive mechanism 48 can be a motor.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
