Description

Technical Field

[0001] This invention relates to the field of high-voltage silicon stack technology, and in particular to a microwave oven high-voltage silicon stack curved foot printing integrated machine. Background Technology

[0002] A high-voltage silicon stack is a type of high-voltage rectifier. When a microwave oven uses a high-voltage silicon stack as a high-voltage rectifier, its pins need to be bent and shaped during the manufacturing process to meet the spatial layout requirements of circuit board insertion or soldering, ensuring precise alignment with PCB holes.

[0003] In the manufacturing process of high-voltage silicon stacks, after the high-voltage silicon stacks are bent, they still need to undergo electrode orientation testing, electrical testing, printing, visual inspection, and packaging. Because bending the feet affects the rotation and printing of the high-voltage silicon stacks, and the electrical testing station and the printing station have different requirements for the high-voltage silicon stack material blocks, there is a lack of equipment in the existing processing equipment that can integrate the above functions, resulting in low production efficiency of high-voltage silicon stacks. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated machine for printing characters on the bent feet of a microwave oven high-pressure silicon stack, so as to solve the problems of inconvenience in printing characters and low production efficiency after bending the feet of the high-pressure silicon stack.

[0012] As a further description of the above technical solution:

[0013] A flipping mechanism is installed on the frame of the UV baking unit. The flipping mechanism includes several flipping motors. The output end of the flipping motor is connected to a toggle lever. The toggle lever is "L"-shaped. The second flow channel is provided with clearance grooves corresponding to the position of the toggle lever. Several clearance grooves and several clearance notches are arranged at intervals.

[0014] As a further description of the above technical solution:

[0015] The visual inspection mechanism includes a pin size inspection camera, a printing rotary wheel, and a printing inspection line scan camera.

[0016] As a further description of the above technical solution:

[0017] The visual inspection and classification mechanism includes a second transport unit, a discharge track, a flip plate, and a baffle plate. The second transport unit is located between the discharge track and the visual inspection mechanism. The flip plate is rotatably mounted on the bottom surface of the discharge track. A collection box with a position corresponding to the flip plate is located below the discharge track. The baffle plate is located at the bottom end of the discharge track.

[0018] As a further description of the above technical solution:

[0019] The conveying mechanism includes a servo motor, a synchronous pulley, a swing arm, and a conveying frame. The output end of the servo motor is connected to the synchronous pulley.

When qualified products discharged from the visual inspection and classification mechanism fall onto the sloping downward section of the conveying mechanism, they first slide away from the lifting section under their own weight and are blocked by the material guide plate to prevent them from falling. At this time, the products are temporarily stored on the sloping downward section, and the products will not collide with and be damaged by the products subsequently discharged by the visual inspection and classification mechanism.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0051] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0052] Example 1

[0053] Please see Figure 1-13 This invention provides a technical solution: a microwave oven high-pressure silicon stacking bending and printing machine, comprising:

[0054] The frame 1 is provided with a first conveyor belt 11 and a second conveyor belt 12 arranged in sequence. A conveying mechanism 13 is provided between the first conveyor belt 11 and the second conveyor belt 12. The frame 1 is also provided with an electrode orientation testing mechanism 14, a rotary orientation mechanism 15, an electrical testing mechanism 16, a printing mechanism 17, a UV baking mechanism 18, and a visual inspection mechanism 19 arranged in sequence along the conveying direction of the first conveyor belt 11.

[0055] Visual inspection and classification mechanism 2 is located at one end of visual inspection mechanism 19;

[0056] The conveying mechanism 3 is located between the visual inspection and sorting mechanism 2 and the receiving and packaging machine 4;

[0057] The first conveyor belt 11 is provided with a first conveyor block 111, which has a V-shaped groove. The high-voltage silicon stack 9 is placed in the V-shaped groove, and the pins 91 of the high-voltage silicon stack 9 are placed on the surface of the first flow channel 112. The second conveyor belt 12 is provided with a second conveyor block 121, which has a U-shaped cross-section. Symmetrically arranged support plates are provided on both sides of the second conveyor block 121, and the support plates have V-shaped notches for supporting the pins 91. Symmetrically arranged second flow channels 122 are provided on both sides of the second conveyor belt 122, and several clearance notches 123 are provided on the second flow channels 122. Symmetrically arranged guide arc surfaces 1231 are provided on opposite sides of the clearance notches 123.

[0058] The microwave oven high-pressure silicon stacking and bending foot printing integrated machine can realize automatic vibratory feeder feeding, electrode testing, electrical testing, product handling, printing, UV baking, visual inspection, product conveying, and product packaging. Only manual feeding to the vibratory feeder is required; the entire process, from feeding to packaging, is fully automated, highly efficient, saves labor costs, and improves production efficiency.

[0059] The electrode orientation test mechanism 14, the rotary orientation mechanism 15, and the electrical test mechanism 16 are connected by a first conveyor belt 11. Since the high-voltage silicon stack does not need to rotate when performing electrical tests at the electrode orientation test mechanism 14 and the electrical test mechanism 16, a V-groove is provided on the first conveyor block 111, and the pins 91 of the high-voltage silicon stack 9 are supported by the first flow channel 112.

[0060] The printing mechanism 17, UV baking mechanism 18, and visual inspection mechanism 19 are connected by a second conveyor belt 12. To facilitate product rotation and angle adjustment, the cross-section of the second conveyor block 121 is U-shaped. Symmetrically arranged support plates are provided on both sides of the second conveyor block 121. The support plates are provided with V-shaped notches for supporting the pins 91 to prevent friction damage to the second conveyor block 121 during product rotation. At the same time, clearance notches 123 are provided on the second flow channel 122 of the printing mechanism 17, UV baking mechanism 18, and visual inspection mechanism 19 to avoid affecting the rotation of the pins 91 of the product.

[0061] The conveying mechanism 3 is V-shaped and includes a sloping section 31 and a lifting section 32. The sloping section 31 extends below the visual inspection and sorting mechanism 2. A material guide plate 331 is provided on the conveyor belt 33 of the conveying mechanism 3. The transition section between the sloping section 31 and the lifting section 32 is pressed down on the conveyor belt 33 by a rotatable roller 34 to maintain tension.

[0062] The conveyor mechanism 3 forms a "V"-shaped belt conveyor line through a specially designed support frame structure. When qualified products discharged from the visual inspection and sorting mechanism 2 fall onto the sloping downward section 31 of the conveyor mechanism 3, they first slide away from the lifting section 32 under their own weight and are blocked by the material guide plate 331 to prevent them from falling. At this time, the products are temporarily stored on the sloping downward section 31, and the products will not collide with and be damaged by the products subsequently discharged from the visual inspection and sorting mechanism 2.

[0063] When the product count on the sloping section 31 reaches the packaging requirement, the conveyor mechanism 3 is activated. The conveyor belt 33 of the conveyor mechanism 3 drives the products upward through the material guide plate 331, and they enter the receiving and packaging machine 4 from the lifting section 32 to achieve counting and packaging.

[0064] The visual inspection mechanism 19 includes a pin size inspection camera 191, a printing rotary wheel 192, and a printing inspection line scan camera 193. The baked product is conveyed to the pin size inspection camera 191 for pin size inspection, and then conveyed to a location below the printing rotary wheel 192. A clearance notch 123 is provided on the second flow channel 122 below the printing rotary wheel 192. The printing rotary wheel 192 contacts the high-voltage silicon stack 9 and, driven by a motor, rotates the high-voltage silicon stack 9 through friction, facilitating the printing quality inspection by the printing inspection line scan camera 193.

[0065] An electrical test defect removal mechanism 161 is provided between the electrical testing mechanism 16 and the conveying mechanism 13. Specifically, there are two electrical test defect removal mechanisms 161. The electrical test defect removal mechanism 161 is used to unload the electrical test defective products from the electrode arrangement testing mechanism 14 and the electrical testing mechanism 16.

[0066] The electrical test defect elimination mechanism 161 includes a first picking robot and a first unloading box. The first picking robot picks up the product and moves in the Z-axis and horizontal directions, thereby placing the product into the first unloading box.

[0067] Working principle: The product's electrodes are tested at the electrode orientation testing mechanism 14. Products with inconsistent electrode orientations are rotated by the rotating orientation mechanism 15 to ensure consistent polarity for all products at the next workstation. The electrode orientation testing mechanism 14 uses a four-probe method to test the polarity of the product pins, determining the positive and negative rotation direction. The rotating orientation mechanism 15 attracts and rotates products with inconsistent polarity directions, ensuring uniform polarity for all products at the next workstation. The Y-axis and rotation are controlled by dual servo motors, resulting in a stable, noiseless, and fast-controllable mechanism. The electrical testing mechanism 16 tests the product's electrical characteristics. The electrode orientation testing mechanism 14, the rotating orientation mechanism 15, and the electrical testing mechanism 16 are existing technologies and will not be described in detail.

[0068] The microwave oven's high-pressure silicon stack uses a printing wheel at the printing mechanism 17 to print characters on circular products. A synchronous pulley connects to a power motor to print different requirements onto the product. After printing, the product enters the UV baking mechanism 18 to bake the printing ink. The baked product is then conveyed to the vision inspection mechanism 19 to inspect the pin dimensions and printing quality. The printing mechanism 17 and the UV baking mechanism 18 are existing technologies and will not be described in detail.

[0069] Example 2

[0070] Based on the above embodiments, this embodiment further improves the following technical solution: A flipping mechanism 5 is provided on the frame 1 at the UV baking mechanism 18. The flipping mechanism 5 includes several flipping motors 51. The output end of the flipping motors 51 is connected to a lever 52. The lever 52 is "L" shaped. A clearance groove 1221 corresponding to the lever 52 is provided on the second flow channel 122. Several clearance grooves 1221 and several clearance notches 123 are arranged at intervals.

[0071] When the product enters the UV baking mechanism 18 for baking, multiple flipping motors 51 are used to rotate the product, combined with the clearance notch 123, to achieve continuous rotation of the product, thereby improving the baking uniformity and baking quality. Referring to the attached diagram, three flipping motors 51 are actually set up, and the three-station rotation ensures that the ink is dried at different angles when printing on round products.

[0072] Specifically, when the high-voltage silicon stack 9 in the second material block 121 moves to the clearance groove 1221, the pin 91 of the high-voltage silicon stack 9 is placed on the toggle lever 52. Then, the flip motor 51 drives the pin 91 and the high-voltage silicon stack 9 to flip 180 degrees. At this time, the pin 91 is placed back on the second flow channel 122.

[0073] The second conveyor belt 12 continues to convey, and the high-voltage silicon stack 9 in the second conveyor block 121 moves to the clearance gap 123. The pins 91 of the high-voltage silicon stack 9 first lose support due to the loss of support of the guide arc surface 1231 on one side. Under the action of gravity, the pins 91 of the high-voltage silicon stack 9 rotate downward and become vertical.

[0074] As the delivery continues, the pins 91 of the high-voltage silicon stack 9 are squeezed and guided to a horizontal state by the guide arc surface 1231 on the other side. The pins 91 are then placed on the second flow channel 122 until they move to the next clearance slot 1221.

[0075] Example 3

[0076] Based on the above embodiments, this embodiment further improves upon the following technical solutions: The visual inspection and classification mechanism 2 includes a second transport unit 21, a discharge track 22, a flip plate 23, and a baffle plate 24. The second transport unit 21 is disposed between the discharge track 22 and the visual inspection mechanism 19. The flip plate 23 is rotatably mounted on the bottom surface of the discharge track 22. A collection box 231 with a position corresponding to the flip plate 23 is disposed below the discharge track 22. The baffle plate 24 is disposed at the bottom end of the discharge track 22.

[0077] The second handling unit 21 uses a suction cup to pick up the visually inspected product and moves along the XZ axis to place the product in the discharge track 22. The product slides down the discharge track 22 under the action of gravity, and the flip plate 23 flips open under the drive of the motor, so that the unqualified product falls into the collection box 231.

[0078] The baffle plate 24 is installed at the output end of the cylinder. It can move downward under the drive of the cylinder to block the bottom of the discharge track 22 and prevent the product from falling. It can also move upward to allow the product to fall.

[0079] Example 4

[0080] Based on the above embodiments, this embodiment further improves upon the following technical solutions: The conveying mechanism 13 includes a servo motor 131, a synchronous pulley 132, a swing arm 133, and a conveying frame 134. The output end of the servo motor 131 is connected to the synchronous pulley 132. The swing arm 133 is fixedly mounted on the rotating shaft of the synchronous pulley 132. The conveying frame 134 is pivotally connected to the swing arm 133. A first suction cup 135 is provided on the conveying frame 134.

[0081] The conveying mechanism 13 transports the high-voltage silicon stack 9 on the first conveyor belt 11 to the second conveyor belt 12. It is controlled by a servo motor, which is fast, efficient and quiet. The synchronous pulley drives the suction and transport, which is accurate in position, high in speed and stable with small swing.

[0082] Example 5

[0083] Based on the above embodiments, this embodiment further improves the following technical solution: a feeding module 6 is provided on one side of the frame 1. The feeding module 6 includes a vibratory feeder 61 and a discharge track 62. One end of the discharge track 62 is connected to the discharge port of the vibratory feeder 61, and the other end extends to the top of the first conveyor belt 11.

[0084] After the product to be processed is manually placed into the vibratory feeder 61, the product in the vibratory feeder 61 is fed into the first conveyor belt 11 via the feeding track 62. A feeding stop mechanism is provided at the end of the feeding track 62 to ensure that the product is fed out individually and matched with the first conveyor belt block 111 on the first conveyor belt 11. The feeding stop mechanism is prior art, and details can be found in the inventor's previously published patents.

[0085] The vibratory plate 61 is placed inside a soundproof cover to reduce operating noise.

[0086] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
