Technical Field

[0002] A rectifier bridge is essentially a rectifier diode encapsulated within a housing. There are full-bridge and half-bridge rectifiers. A full-bridge rectifier encapsulates four diodes connected in a bridge rectifier circuit. A half-bridge rectifier encapsulates half of the four diodes used in a bridge rectifier circuit; two half-bridges can be used to form a bridge rectifier circuit. After production, rectifier bridges undergo high-voltage testing to determine their quality. The testing method involves applying high voltage to the bridge's pins and measuring the voltage across its insulating housing. If voltage is detected on the housing, the rectifier bridge fails; if no voltage is detected, the high-voltage test is successful.

This results in fast detection speed and more accurate detection.

[0062] The inspection conveying device 42 includes an inspection transfer device, an inspection reciprocating motion device, a waste output trough 6, and an inspection translation device.

The inspection translation frame 50 is slidably mounted on the upper side of the inspection mounting base 41, which is mounted on the frame 1. The piston rod of the inspection translation cylinder is connected to the inspection translation frame 50 and pushes the inspection translation frame 50 to move towards or away from the inspection transfer device. The inspection translation cylinder is mounted on the inspection mounting base 41. The inspection cover-closing cylinder 53, the cover-closing guide rail 51, and the waste material trough body 49 are all mounted on the inspection translation frame 50. The inspection translation cylinder can be replaced with a translation linear module.

[0066] like Figure 9 , 11 As shown: The detection reciprocating moving device includes a detection reciprocating moving cylinder (not shown in the figure) and a detection conveyor frame 55.

[0067] The detection positioning section includes a detection positioning plate 56 disposed on the upper side of the detection conveyor 55. Several detection positioning plates 56 are arranged side by side along the direction of movement perpendicular to the detection conveyor 55. Each detection positioning plate 56 has a detection positioning groove 5601 on its top for accommodating the rectifier bridge, thus forming the detection positioning section.

[0068] like Figure 12 As shown: The detection lifting device includes a detection lifting frame and a detection lifting cylinder 40. The detection lifting frame includes a detection lifting upright plate 38 and a detection lifting base plate 39. The detection lifting base plate 39 is horizontally arranged below the detection mounting seat 41. There are two detection lifting upright plates 38 symmetrically arranged on both sides of the detection lifting base plate 39. The bottom of each detection lifting upright plate 38 is fixedly connected to the detection lifting base plate 39, and the top of the detection lifting upright plate 38 is fixedly connected to the primary detection component 43. The detection lifting cylinder 40 is vertically arranged. The piston rod of the detection lifting cylinder 40 is fixedly connected to the middle of the detection lifting base plate 39, and drives the primary detection component 43 to rise and fall through the detection lifting base plate 39 and the detection lifting upright plate 38.

[0069] The detection lifting cylinder 40 is located on the upper side of the detection lifting base plate 39. The detection lifting cylinder 40 can be installed on the detection mounting base 41. The detection lifting cylinder 40 can be replaced by a detection linear module.

[0070] like Figure 13 As shown: The primary testing assembly 43 includes a testing frame 57 and testing blocks 58 and energizing blocks 59 mounted on the bottom of the testing frame 57, forming a testing section and an energizing section. Several testing blocks 58 are arranged side-by-side along the testing frame 57, and each energizing block 59 corresponds to one testing block 58. The energizing blocks 59 and testing blocks 58 are arranged sequentially along the conveying direction of the rectifier bridge. Testing positioning plates 56 also correspond one-to-one with the testing blocks 58. When the testing positioning plates 56 move directly below the testing frame 57, both the energizing blocks 59 and testing blocks 58 are directly aligned with their corresponding positioning plates 56. A pin 5801 is provided in the lower center of the testing block 58. The pin 5801 is vertically positioned. When testing the rectifier bridge, the pin 5801 extends into the through-hole of the rectifier bridge, ensuring that the energizing blocks 59 and testing blocks 58 are respectively aligned with the pins and insulating shell of the rectifier bridge.

[0071] A detection buffer device is provided between each detection block 58 and the detection frame 57, and an energizing buffer device is provided between each energized block 59 and the detection frame 57. The energizing buffer device and the detection buffer device have the same structure. In this embodiment, the structure of the energizing buffer device is used as an example to describe the structure of the energizing buffer device and the detection buffer device.

[0072] The energizing buffer device includes an energizing block mounting rod 61 and an energizing block buffer spring 60. Both the energizing block mounting rod 61 and the energizing block buffer spring 60 are located on the lower side of the detection frame 57. The bottom of the energizing block mounting rod 61 is fixedly connected to the corresponding energizing block 59, and the top of the energizing block mounting rod 61 slidably through the detection frame 57 and is fixedly connected to the energizing block limiting plate 63. The energizing block buffer spring 60 is sleeved on the energizing block mounting rod 61, and its two ends are supported on the detection frame 57 and the energizing block 59, respectively. The energizing block buffer spring 60 is in a compressed state. When the energizing block 59 contacts the pins of the rectifier bridge, the energizing block buffer spring 60 can prevent a rigid collision between the energizing block 59 and the rectifier bridge, and can also provide a certain preload between the energizing block 59 and the pins of the rectifier bridge, ensuring reliable contact between the energizing block 59 and the pins of the rectifier bridge.

[0073] The testing frame 57 is provided with a power block mounting sleeve 62. The upper end of the power block mounting rod 61 can slide through the power block mounting sleeve 62 and connect to the power block limiting plate 63. The power block limiting plate 63 can prevent the power block mounting rod 61 from detaching from the testing frame 57 under the action of the power block buffer spring 60.

[0074] Two power block mounting rods 61 are arranged side by side on the upper side of each power block 59. The top of the two power block mounting rods 61 is connected to the same power block limiting plate 63. Power block buffer springs 60 are sleeved on the outside of the two power block mounting rods 61 to ensure reliable contact between the power block 59 and the pins of the rectifier bridge.

[0075] like Figure 14 As shown: The detection transfer device includes a transfer lifting device and a detection suction device 47. The transfer lifting device is connected to the detection suction device 47 and drives it to rise and fall. The detection suction device 47 is located on the upper side of the detection reciprocating moving device.

[0076] The transfer lifting device includes a transfer lifting base plate 44, a transfer guide shaft 45, a transfer guide sleeve 46, and a transfer lifting cylinder 64. The transfer lifting base plate 44 is located below the detection mounting base 41. The transfer guide shaft 45 is vertically arranged on both sides of the transfer lifting base plate 44, with its bottom fixedly connected to the transfer lifting base plate 44 and its top fixedly connected to the detection and suction device 47. The transfer lifting cylinder 64 is vertically arranged, with its piston rod connected to the middle of the transfer lifting base plate 44, and drives the detection and suction device 47 to rise and fall through the transfer lifting base plate 44 and the transfer guide shaft 45. Each transfer guide shaft 45 is slidably fitted with a transfer guide sleeve 46, which is mounted on the frame 1. The transfer lifting cylinder 64 is located between the transfer lifting base plate 44 and the detection mounting base 41, and can be installed at the bottom of the detection mounting base 41. The transfer lifting cylinder 44 can also be a transfer linear module.

[0077] The detection suction device 47 includes a suction cup mounting plate 65 and detection suction cups 66. The suction cup mounting plate 65 is horizontally arranged, and both ends of the suction cup mounting plate 65 are connected to a transfer lifting device. Specifically, both ends of the suction cup mounting plate 65 are fixedly connected to the corresponding transfer guide shaft 45. The detection suction cups 66 are installed at the bottom of the suction cup mounting plate 65, and several detection suction cups 66 are arranged side-by-side along the suction cup mounting plate 65. In this embodiment, the detection suction cups 66 correspond one-to-one with the detection positioning plates 56. When the detection positioning plates 56 move to the underside of the suction cup mounting plate 65, the detection suction cups 66 and the corresponding detection positioning plates 56 are positioned facing each other.

[0078] The detection suction cups 66 are arranged in pairs, with two detection suction cups 66 corresponding to each detection positioning part. A suction guide rod is provided between the two detection suction cups 66. The bottom of the suction guide rod is set lower than the bottom of the detection suction cup 66. The suction cup guide rod is used to extend into the through hole of the rectifier bridge to ensure that the detection suction cup 66 is aligned with the insulating shell of the rectifier bridge.

[0079] like Figure 15 As shown: The secondary inspection device 7 includes a secondary inspection component and an inspection groove 68. The inspection groove 68 is located on the upper side of the secondary inspection component, and its outlet is connected to the inlet of the appearance inspection device 9. The secondary inspection component has the same structure as the primary inspection component 43, and its structure will not be described again here. The secondary inspection component is slidably mounted on the frame 1, and is connected to a secondary inspection cylinder that drives its lifting and lowering.

[0080] The conveying assembly 5 includes a pushing device 13 and a steering track assembly 69. The steering track assembly 69 has an input channel and an output channel. The input channel is located on one side of the output channel, and its output end is connected to the input end of the output channel. An input guide is located on one side of the input channel. The pushing device has a pushing part that extends into the input channel. The output end of the output channel is connected to the inlet of the detection slot 68. The steering track assembly 69 has an input channel and an output channel. The input channel is located on one side of the output channel. The pushing part of the pushing device is located in the input channel and pushes the rectifier bridge on the input channel to move into the output channel. The rectifier bridge in the output channel can be conveyed by compressed air or can rotate synchronously with the corresponding conveyor line, thus realizing the switching of rectifier bridge conveying between different conveyor lines. This facilitates the conveying of rectifier bridges from the conveyor line to the detection line. The input guide can guide the rectifier bridge entering the input channel, facilitating accurate delivery of the rectifier bridge from the output channel and providing conditions for automatic detection of the rectifier bridge.

[0081] A transfer conveyor trough 67 is also provided between the steering track assembly 69 and the primary detection device 3. The inlet of the transfer conveyor trough 67 is connected to the qualified material outlet of the primary detection device 3. In this embodiment, the transfer conveyor trough 67 and the detection trough 68 are arranged parallel to each other, and the detection trough 68 is located inside the transfer conveyor trough 67. The input channel and the output channel of the steering track assembly 69 are arranged perpendicularly. The input channel is arranged perpendicularly to the transfer conveyor trough 67. The input end of the input channel is located on the side of the discharge port of the transfer conveyor trough 67, and the input guide is located on the side of the input channel away from the transfer conveyor trough 67 to ensure the accurate positioning of the rectifier bridge conveyed into the input channel.

[0082] The opening of the transfer conveyor 67 faces away from the steering track assembly 69. When the rectifier bridge is conveyed within the transfer conveyor 67, its pins pass through the opening and extend out. Several air nozzles 132 are installed on the upper side of the transfer conveyor 67. The air nozzles 132 are inclined downwards along the conveying direction of the rectifier bridge. The air nozzles 132 blow compressed air, which in turn causes the rectifier bridge to be conveyed within the transfer conveyor 67.

[0083] The opening of the detection trough 68 faces the side closest to the steering track assembly 69, meaning the opening of the detection trough 68 faces the same direction as the opening of the transfer conveyor trough 67. This allows the rectifier bridge to be directly transferred from the transfer conveyor trough 67 to the detection trough 68 without rotating when switching conveyor lines. Several air nozzles 132 are also installed on the upper side of the detection trough 68. The air nozzles 132 are angled downwards along the conveying direction of the rectifier bridge, blowing compressed air to transport the rectifier bridge within the detection trough 68.

[0084] The detection slot 68 has a detection port 6801 in the middle. When the rectifier bridge is tested, since the pins of the rectifier bridge extend out of the detection slot 68, the secondary detection component directly powers the pins of the rectifier bridge that have moved to the detection port 6801. Then, the insulating shell of the rectifier bridge is tested through the detection port 6801, so that the rectifier bridge can be tested directly on the detection line.

[0085] A cleaning movable cover plate 71 is provided on the upper side of the output end of the detection tank 68. The cleaning movable cover plate 71 is located on the upper side of the output end of the detection tank 68 and closes the upper side of the detection tank 68. A cleaning cover-closing cylinder 70 is connected to the cleaning movable cover plate 71. The cleaning cover-closing cylinder 70 is located on the bottom side of the detection tank 68 and is connected to the cleaning movable cover plate 71 through a movable cover plate push plate 72.

[0086] like Figures 16-17As shown: The steering track assembly 69 includes a support plate 73 and a cover 74. The support plate 73 is horizontally arranged, and a protruding mounting part is provided on one side of the support plate 73. The cover 74 is located on the upper side of the support plate 73, and the cover 74 is connected to the mounting part, forming a vertical input channel and an output channel between the support plate 73 and the cover 74.

[0087] The input guide includes a positioning platform 7304 disposed on the upper side of the tray 73. The positioning platform 7304 protrudes upward from the tray 73 and is disposed along the input channel, on the side of the input channel away from the transfer conveyor 67. The mounting part and the positioning platform 7304 are disposed on opposite sides of the input channel. One side of the pressure cover 74 is supported on the positioning platform 7304, and the other side is connected to the mounting part. When the rectifier bridge in the transfer conveyor 67 enters the input channel, the side of the positioning platform 7304 can position the rectifier bridge, ensuring that the rectifier bridges in the input channel are neatly arranged.

[0088] The conveying assembly 5 also includes a cover clamping spring 75, which is disposed on the upper side of the cover 74. The upper end of the mounting part is bent towards the cover 74, and a clamping part is formed on the top of the mounting part. The cover clamping spring 75 is disposed between the clamping part and the cover 74. The cover clamping spring 75 is in a compressed state. The top of the cover clamping spring 75 is connected to the clamping part, and the bottom is connected to the cover 74, and pushes the cover 74 to clamp the positioning table 7304. Several cover clamping springs 75 are arranged side by side. Due to the presence of the cover clamping spring 75, a flexible connection can be achieved between the cover 74 and the support plate 73, allowing the cover 74 to move vertically to avoid damage to the rectifier bridge.

[0089] Furthermore, to ensure more stable lifting and lowering of the pressure cap 74, a guide post is provided between the support plate 73 and the pressure cap 74. The bottom of the guide post is fixedly connected to the support plate 73, and the top of the guide post is slidably connected to the pressure cap 74.

[0090] The pallet 73 is also provided with a pusher elongated hole 7301, which is directly opposite to the input channel. There are two pusher elongated holes 7301 arranged side by side and spaced apart, so that the pushing part of the pusher device 13 can pass through the pusher elongated hole 7301 and extend into the input channel to drive the rectifier bridge in the input channel to move.

[0091] The conveying assembly 5 also includes a positioning device and a pressing device disposed at the output end of the input channel. The positioning device is disposed directly opposite to the input end of the output channel. The positioning device is mounted on the tray 73, and the pressing device is mounted on the pressure cover 74. The bottom of the pressing device is provided with a pressing part, and the pressure cover 74 is provided with a through hole for the pressing part to pass through. The pressing part is disposed directly below the positioning device.

[0092] The positioning device includes a positioning port 7302 and a rectifier bridge positioning plate 79. The top of the support plate 73 is recessed to form the positioning port 7302, which is located at the output end of the input channel. A vertical support portion 7303 is formed on the side of the positioning port 7302 away from the output channel. The rectifier bridge positioning plate 79 is slidably mounted on the upper side of the support plate 73. The rectifier bridge positioning plate 79 and the support portion 7303 are located on opposite sides of the positioning port 7302. The support portion 7303, the rectifier bridge positioning plate 79, and the positioning port 7302 together form an upward-opening groove. A vertical pushing portion 7901 is provided at the end of the rectifier bridge positioning plate 79 near the positioning port 7302, and the pushing portion 7901 is directly opposite the support portion 7303. The input end of the output channel is directly opposite the positioning port 7302, and the input port of the output channel is located between the support portion 7303 and the pushing portion 7901.

[0093] When the rectifier bridge in the input channel moves to the upper side of the positioning port 7302, the pressing device pushes the rectifier bridge downwards, causing the entire insulating shell of the rectifier bridge to enter the positioning port 7302 and be positioned between the support part 7303 and the pushing part 7901, thus achieving the positioning of the rectifier bridge. The pressing device actuates and pushes the rectifier bridge into the positioning port 7302 to ensure reliable positioning.

[0094] To ensure that the rectifier bridge can smoothly enter the positioning port 7302 and avoid the rectifier bridge getting stuck between the support part 7303 and the pushing part 7901 due to tilting, in this embodiment, the rectifier bridge positioning plate 79 is connected to a rectifier bridge positioning cylinder 78 that drives it to move along the support plate 73. The rectifier bridge positioning cylinder 78 is installed on the support plate 73, and the piston rod of the rectifier bridge positioning cylinder 78 is connected to the rectifier bridge positioning plate 79 and pushes the rectifier bridge positioning plate 79 to move in the direction of approaching or moving away from the support part 7303. When the rectifier bridge enters the positioning port 7302, the rectifier bridge positioning cylinder 78 drives the rectifier bridge positioning plate 79 to move away from the support part 7303, thereby increasing the distance between the pushing part 7901 and the support part 7303, so that the rectifier bridge can smoothly enter the positioning port 7302. After the rectifier bridge enters the positioning port 7302, the rectifier bridge positioning cylinder 78 pushes the rectifier bridge positioning plate 79 to move closer to the support part 7303, so that the pushing part 7901 and the support part 7301 cooperate to position the rectifier bridge.

[0095] The pressing device includes a pressing cylinder 76 and a pressing frame 77. The pressing cylinder 76 is vertically mounted on the mounting part. The pressing frame 76 is located between the pressing cylinder 77 and the pressure cover 74. The piston rod of the pressing cylinder 76 is connected to the pressing frame 77 and pushes the pressing frame 77 to rise and fall. The pressing part is located at the bottom of the pressing frame 77. Several pressing parts are arranged side by side and spaced apart along the pressing frame 77.

[0096] An air nozzle 132 is installed on the pressure cover 13 between the pushing device 13 and the positioning port 7302. The air nozzle 132 is inclined downward along the pushing direction of the pushing device 13 to assist the rectifier bridge in conveying, so that the rectifier bridge pushed by the pushing device 13 enters the positioning port 7302.

[0097] The output channel is flush with the positioning port 7302 to ensure that the rectifier bridge can smoothly enter the output channel from the positioning port 7302. An air nozzle 132 is provided on the upper or lower side of the output channel. The air nozzle 132 is inclined and gradually approaches the output channel along the conveying direction of the rectifier bridge to facilitate the conveying of the rectifier bridge.

[0098] like Figure 18 As shown, the pushing device 13 includes a pushing power unit and a rectifier bridge pushing device disposed on the lower side of the pallet 73. The rectifier bridge pushing device is equipped with a rectifier bridge pushing section, and the pushing power unit is connected to the rectifier bridge pushing device. The pushing power unit drives the rectifier bridge pushing device to move, and the rectifier bridge pushing section pushes the rectifier bridge on the pallet 73 to move. This enables the rectifier bridge to be transferred between different equipment or production lines, and allows the rectifier bridge to make right-angle turns during the conveying process, making the rectifier bridge conveying more flexible and providing conditions for the automatic detection of the rectifier bridge.

[0099] The feeding device 13 also includes a feeding mounting frame 80 and a feeding section detection device. The feeding mounting frame 80 is spaced apart on the lower side of the support plate 73 and is fixedly connected to the support plate 73 by mounting columns. The feeding power unit is mounted on the feeding mounting frame 80, and the rectifier bridge pushing device is located between the support plate 73 and the feeding mounting frame 80. The feeding power unit is connected to the rectifier bridge pushing device. The top of the rectifier bridge pushing device is provided with a rectifier bridge pushing section. The upper part of the rectifier bridge pushing section passes upward through the feeding elongated hole 7301 and extends upward to push the rectifier bridge in the input channel. The feeding section detection device is located between the feeding power unit and the feeding mounting frame 80. The feeding detection device detects the position of the rectifier bridge pushing section by detecting the feeding power unit.

[0100] The rectifier bridge pushing device includes a rectifier bridge pusher frame 89 and a pusher rod 8901. The rectifier bridge pusher frame 89 is disposed between the support plate 73 and the pusher mounting frame 80. The top of the pusher mounting frame 80 is provided with a clearance opening. The bottom of the rectifier bridge pusher frame 89 is bent downwards. The bottom of the rectifier bridge pusher frame 89 slidably passes through the clearance opening and connects to the pusher power device, and moves with the pusher power device. The pusher rod 8901 is vertically disposed on the top of the rectifier bridge pusher frame 89, forming the rectifier bridge pushing part. The bottom of the pusher rod 8901 is fixedly connected to the rectifier bridge pusher frame 89, and the top of the pusher rod 8901 slidably passes upwards through the pusher elongated hole 7301. Two pushers 8901 are arranged side by side with a gap between them, and the pusher elongated hole 7301 corresponds one-to-one with the pusher rod 8901.

[0101] The material pushing power unit includes a material pushing lifting assembly, a material pushing translation assembly, and a power unit. Both the material pushing lifting assembly and the material pushing translation assembly are mounted on the material pushing mounting frame 80 and are connected to the rectifier bridge material pushing frame 89. The power unit is connected to both the material pushing lifting assembly and the material pushing translation assembly. Specifically, the material pushing translation assembly is mounted on the material pushing mounting frame 80, the material pushing lifting assembly is mounted on the material pushing translation assembly, and the material pushing mounting frame 80 is mounted on the material pushing lifting assembly.

[0102] The power unit includes a pusher motor 81 and a pusher transmission mechanism. The pusher motor 81 is mounted on the pusher mounting frame 80.

One end of the lifting link 84 is hinged to the other end of the translation link 83, and the other end of the lifting link 84 is hinged to the feeding lifting frame 86. When the pusher motor 81 pushes the pusher translation frame 85 to the right via the crank 82 and the translation linkage 83, the translation linkage 83 cooperates with the lifting linkage 84 to push the pusher lifting frame 84 upward, and causes the upper end of the push rod 8901 to extend upward beyond the support plate 73, thereby pushing the rectifier bridge to move along the input channel; when the pusher motor 81 drives the pusher translation frame 85 to the left via the crank 82 and the translation linkage 83, the translation linkage 83 and the lifting linkage 84 drive the pusher lifting frame 86 downward, and cause the top end of the push rod 8901 to move to the lower side of the support plate 73, so as to avoid mutual obstruction between the push rod 8901 and the rectifier bridge.

[0106] Preferably, the distance between the hinge axis of the translation link 83 and the hinge axis of the pusher translation frame 85 and the hinge axis of the translation link 83 and the crankshaft 82 is greater than the distance between the hinge axis of the translation link 83 and the pusher translation frame 85 and the hinge axis of the translation link 83 and the lifting link 84. Simultaneously, the hinge axis of the translation link 83 and the pusher translation frame 85 is located below the output shaft of the pusher motor 81 to provide a quick-return characteristic when the pusher translation frame 85 moves to the left.

[0107] A feeding buffer device is provided between the rectifier bridge driving device and the feeding power device.

[0110] like Figures 19-20As shown: The appearance inspection device 9 includes a CCD inspection component and a rotating device. Several inspection stations are arranged around the side of the rotating device. The CCD inspection component is mounted on the frame 1, and multiple sets of CCD inspection components are arranged around the rotating device to realize the inspection of the appearance of the rectifier bridge in various directions. Rectifier bridge pushing cylinders or robotic arms are arranged between the output port of the inspection tank 68 and the rotating device, between the rotating device and the waste collection device 9, and between the rotating device and the rectifier bridge receiving device 11, so as to realize the transfer of the rectifier bridge from the inspection tank 68 to the inspection station of the rotating device, or from the inspection station to the waste collection device 9 and the rectifier bridge receiving device 11.

[0111] The appearance inspection device also includes a rotary motor 100 and a fixed frame 94.

[0129] like Figures 24-26As shown: The rectifier bridge receiving device 11 includes a rectifier bridge conveying device and a trough alignment device. The trough alignment device is located at the output end of the rectifier bridge conveying device, and has an alignment section that faces the trough conveying device. The alignment section ensures that the trough and the output end of the rectifier bridge conveying device are aligned. The rectifier bridge conveying device transports the rectifier bridge into the trough, thus automatically feeding the rectifier bridge into the trough, increasing the speed at which the rectifier bridge is placed into the trough, and preventing the rectifier bridge from colliding with the end of the trough and causing damage.

[0130] The rectifier bridge receiving device 11 also includes a discharge platform 124 and a material trough temporary storage bin 126, a material trough transfer device, a material trough storage bin 125, a material trough lifting device, and a material trough docking device installed on the discharge platform 124.

The lifting cylinder 129 is vertically installed at the bottom of the discharge platform 124, and the lifting plate 130 is located on the upper side of the discharge platform 124. The piston rod of the lifting cylinder 129 can slide through the discharge platform 124 and connect with the lifting plate 130, thereby driving the lifting plate 130 to rise and fall. The lifting plate 130 is positioned directly opposite the material trough storage bin 125.

[0133] The trough docking device is located directly below the trough temporary storage bin 126 and is mounted on the discharge platform 124. This device drives the trough at the bottom of the trough temporary storage bin 126 towards the rectifier bridge conveyor, causing the end of the trough at the bottom of the trough temporary storage bin 126 to extend beyond the opening and align with the input end of the rectifier bridge conveyor. A trough alignment device is installed on the upper side of the discharge platform 124, positioned between the output end of the rectifier bridge conveyor and the trough temporary storage bin 126. This device aligns the trough at the bottom of the trough temporary storage bin 126 with the output end of the rectifier bridge conveyor, ensuring that the trough at the bottom of the trough temporary storage bin 126 is directly opposite the output end of the rectifier bridge conveyor.

[0134] The material conveying device includes an output cylinder 131 and air nozzles 132. One end of the output cylinder 131 is mounted on the discharge platform 124. The output end of the output cylinder 131 is directly opposite the bottom of the material storage bin 126, and the material storage bin 126 has an opening on the side near the output cylinder 131 to facilitate the rectifier bridge inside the output cylinder 131 entering the material trough at the bottom of the material storage bin 126. A clearance groove is provided on one side of the output cylinder 131. Several air nozzles 132 are arranged at intervals along the output cylinder 131. The air nozzles 132 are inclined and gradually approach the output cylinder 131 along the conveying direction of the rectifier bridge. The compressed air ejected by the air nozzles 132 blows the rectifier bridge to move inside the output cylinder 131, thereby realizing the conveying of the rectifier bridge.

[0135] The rectifier bridge receiving device also includes a material pushing device, a material blocking device, and a locking device. The material pushing device is located at the input end of the output cylinder 131, and the material blocking device and the locking device are both located on the lower side of the output end of the output cylinder 131, so as to block and lock the rectifier bridge when replacing the empty material trough.

[0136] The material feeding device includes a rectifier bridge discharge cylinder 133 and a rectifier bridge push-out block 138. The rectifier bridge discharge cylinder 133 is installed at the input end of the output cylinder 131, and the rectifier bridge push-out block 138 is installed on the piston rod of the rectifier bridge discharge cylinder 133. The rectifier bridge discharge cylinder 133 pushes the rectifier bridge push-out block 138 to move towards or away from the output cylinder 131. A rectifier bridge input platform is provided at the input end of the output cylinder 131. The rectifier bridge is placed on the rectifier bridge input platform, and the rectifier bridge discharge cylinder 133 drives the rectifier bridge push-out block 138 to move, pushing the rectifier bridge into the output cylinder 131.

[0137] The trough centering device includes a centering cylinder 136 and a centering plate. The centering plate is located above the output end of the output cylinder 131, and the centering cylinder 136 is vertically positioned above the centering plate. The centering cylinder 136 is mounted on the trough temporary storage chamber 126. The piston rod of the centering cylinder 136 is connected to the centering plate and drives the centering plate to rise and fall. Centering fingers are provided on both sides of the centering plate. The centering fingers are located on the lower side of the centering plate and form a centering section between the two pairs of centering fingers. The lower part of the inner wall of each pair of centering fingers is inclined from bottom to top, so that the width of the outer side of the centering section gradually narrows from the outside to the inside. When the centering cylinder 136 pushes the centering plate downward, the centering section gradually centers and positions the two sides of the trough.

[0138] The material trough transfer device includes a material trough push plate 127 and a transfer cylinder 140. The material trough push plate 127 is slidably mounted on the discharge platform 124. A collection positioning groove is provided on the top of the material trough push plate 127. The width of the collection positioning groove is greater than the width of the material trough, and the depth of the collection positioning groove is equal to or less than the thickness of the material trough. The piston rod of the transfer cylinder 140 is fixedly connected to both material trough push plates 127 through the push-out connector 128 and pushes them to move synchronously.

[0139] Material trough support assemblies are provided at both ends of the material trough storage bin 125. Each material trough support assembly includes support fingers 137 provided on both sides of the material trough storage bin 125. The bottom sides of the material trough storage bin 125 are provided with mounting ports. The support fingers 137 are installed in the mounting ports. The bottom of the support fingers 137 is rotatably connected to the material trough storage bin 125. The top of the support fingers 137 is a horizontal support part. The bottom of the support fingers 137 is an inlet part that gradually slopes outward from top to bottom. A finger return spring (not shown in the figure) is provided between the support fingers 137 and the material trough storage bin 125. When the finger return spring is in a compressed state, it pushes the support fingers 137 to move, so that the upper part of the finger support fingers 137 extends into the material trough storage bin 125.

[0140] When the trough lifting device pushes the trough filled with rectifier bridges upward, the trough pushes the inner end of the support finger 137 upward through the inlet to avoid obstructing the lifting of the trough. When the trough is lifted to the upper side of the support finger 137, the support finger 137 is reset under the action of the finger reset spring and supports the bottom of the trough, thus realizing the stacking of the troughs.

[0141] The trough docking device includes a trough support device and a trough pushing device. The trough support device is positioned opposite the rectifier bridge conveyor device. The trough pushing device is connected to the trough support device and pushes the trough support device to move closer to or away from the rectifier bridge conveyor device. The trough support device supports the trough, and the trough pushing device pushes the trough to move closer to or away from the conveyor cylinder 8, thus achieving docking between the trough and the output cylinder 131, ensuring that the rectifier bridge in the output cylinder 131 smoothly enters the trough.

[0142] The material trough support device includes a rectifier bridge discharge cylinder 139, which is installed on the discharge platform 124.

The material blocking cylinder 135 is vertically installed on the lower side of the output cylinder 131, and the material blocking block is installed on the piston rod of the material blocking cylinder 135. The bottom of the output cylinder 131 is provided with a through hole for the material blocking block to extend into. The material blocking cylinder 135 drives the material blocking block to move and extends the material blocking block into the output cylinder 131 to block the rectifier bridge in the output cylinder 131.

[0145] The locking device includes a locking cylinder 134 and a locking pin. The locking cylinder 134 is installed on the lower side of the output cylinder 131, and the locking pin is installed on the piston rod of the locking cylinder 134. The bottom of the output cylinder 131 is also provided with a through hole for the locking pin to extend into. The locking cylinder 134 pushes the locking pin into the output cylinder 131 and into the through hole of the rectifier bridge, thereby realizing the locking of the rectifier bridge.

[0146] The working process of this rectifier bridge testing device is as follows: The rectifier bridge input component 2 transports the rectifier bridges in the material trough one by one into the input trough 12. The pushing device 13 pushes the rectifier bridges in the input trough 12 one by one into the test pushing device 4. The test pushing device 4 pushes the rectifier bridges into the primary testing device 3. The primary rectifier bridge testing device 3 tests the rectifier bridges.

After testing, the rectifier bridges are wiped and marked in sequence and then enter the appearance testing device 9 for appearance testing. The qualified rectifier bridges enter the rectifier bridge collection device 11, and the unqualified rectifier bridges enter the waste collection device 10.
