Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a novel flatness straightening machine. Background Technology

[0002] For surface mount electronic components, such as small surface mount transformers, the soldered ends of the pins extend horizontally out of the component housing. During the manufacturing process of surface mount electronic components, the pins may become deformed, skewed, or uneven. To ensure the quality of the electronic components, the pins of surface mount electronic components need to be trimmed.

[0003] Among them, the Chinese utility model patent with patent number ZL202121187770.3 and patent name: A Pin Flattening and Inspection Device for Transformers, substantially discloses a pin flattening machine; specifically, the pin flattening and inspection device for transformers discloses the following technical solution: A pin flattening and inspection device for transformers includes a frame, a conveying mechanism set on the frame, a feeding mechanism, two opposing first visual inspection mechanisms, a flattening mechanism, two opposing second visual inspection mechanisms, and a unloading mechanism arranged sequentially next to the conveying mechanism; the conveying mechanism is used for the cyclic conveying of products; each visual inspection mechanism includes a visual camera fixing plate, a camera, a light source fixing plate, and a light source; the flattening mechanism includes a fixture clamping mechanism, two bending mechanisms, and two lead screw reciprocating mechanisms, the fixture clamping mechanism is placed between the two bending mechanisms, the fixture clamping mechanism is used to position the product, and the bending mechanism is used to flatten the pins of the product positioned by the fixture clamping mechanism; each bending mechanism corresponds to The components are mounted on a lead screw reciprocating mechanism. Each actuating mechanism includes a slide rail, a sliding frame mounted on the slide rail, a first geared motor mounted on the sliding frame, a gear assembly connected to the output end of the first geared motor, a pneumatic gripper cylinder connected to the gear assembly, and a gripper located at the output end of the pneumatic gripper cylinder. When the first geared motor is driven, it drives the gear assembly to rotate, which in turn drives the pneumatic gripper cylinder to move up and down, thereby flattening the product stitches gripped by the gripper. The fixture clamping mechanism includes a fixture fixing table, a lower fixture mold mounted on the fixture fixing table, an upper fixture mold that cooperates with and is mounted on the lower fixture mold, and a drive motor for driving the upper fixture mold. The lead screw reciprocating mechanism includes a second geared motor, a coupling located at the output end of the second geared motor, a lead screw connected to the coupling, and a lead screw nut mounted on the lead screw. The lead screw nut can move back and forth on the lead screw. The sliding frame passes through the worktable and is connected to the lead screw nut. The back and forth movement of the lead screw nut drives the sliding frame to slide back and forth on the slide rail.

[0004] When the aforementioned TN patch transformer pin leveling equipment is working, the product is conveyed to the first vision inspection mechanism for inspection via a conveying mechanism. If the product passes the first inspection, it does not need to proceed to the next station. Unqualified products are conveyed to the leveling mechanism for leveling and then sent to the second vision inspection mechanism for inspection. Qualified products are conveyed to the unloading mechanism for unloading, while unqualified products are returned for re-leveling. During the leveling operation, the transformer is placed in the working position of the upper and lower molds of the fixture. The drive motor drives the upper mold of the fixture to press down, clamping and positioning the transformer. The second reduction motor of the lead screw reciprocating mechanism drives the sliding frame to slide on the slide rail and move to the pin clamping position. The pneumatic gripper cylinder drives the gripper to clamp the pin. The first reduction motor of the prying mechanism drives the gear assembly to rotate, which in turn drives the pneumatic gripper cylinder to pry the pin up and down, thereby leveling the pin.

[0005] It should be noted that the above-mentioned TN patch transformer pin leveling equipment still has the following defects: the first visual inspection mechanism, the leveling mechanism, and the second visual inspection mechanism are arranged alternately along the conveying direction of the conveying mechanism. The first visual inspection mechanism is used to inspect the pin flatness before the leveling mechanism, and the second visual inspection mechanism is used to inspect the pin flatness after the leveling mechanism. However, the arrangement of the first visual inspection mechanism, the leveling mechanism, and the second visual inspection mechanism alternately along the conveying direction of the conveying mechanism results in a large overall footprint and poor structural compactness of the device. In addition, the use of two visual inspection mechanisms to perform the inspection increases the cost. Utility Model Content

Detailed Implementation

[0021] The present invention will now be described in conjunction with specific embodiments.

[0022] Example 1, as Figures 1 to 4 As shown, a novel flatness adjustment machine includes a base 1, on which a product fixing fixture assembly 2 is mounted, two automatic foot adjustment components 3 are arranged opposite each other on the left and right sides of the product fixing fixture assembly 2, and two CCD vision inspection components 4 are arranged opposite each other on the left and right sides of the product fixing fixture assembly 2.

[0023] Specifically, such as Figures 1 to 3 As shown, the product fixing fixture assembly 2 includes a lower fixture mold 21 and an upper fixture mold 22 located directly above the lower fixture mold 21. The base 1 is equipped with a vertically moving clamping drive cylinder 23 corresponding to the upper fixture mold 22, and the drive end of the clamping drive cylinder 23 is connected to the upper fixture mold 22.

[0024] Among them, such as Figures 1 to 4 As shown, each CCD vision inspection component 4 includes a camera mounting base 41 and a CCD industrial camera 42 mounted on the camera mounting base 41.

[0025] Furthermore, such as Figures 1 to 3 As shown, the product fixing fixture assembly 2 also includes a horizontal slide 24 that is horizontally slidably mounted on the base 1, and the lower mold 21 of the fixture is mounted on the horizontal slide 24. The base 1 is equipped with a slide drive (not shown in the figure) that moves horizontally back and forth, corresponding to the horizontal slide 24. The slide drive drives the horizontal slide 24 to reciprocate between the upper and lower workstation and the measuring and aligning workstation. It should be explained that, in order to ensure that the horizontal slide 24 is stably and reliably mounted horizontally back and forth on the base 1, this embodiment can guide the horizontal slide 24 through a guide rail slider pair 25, that is, a guide rail slider pair 25 is installed between the horizontal slide 24 and the base 1.

[0026] It should be noted that the slide drive component in this embodiment can be a cylinder or an electric push rod.

[0027] Furthermore, such as Figures 1 to 4 As shown, each CCD vision inspection component 4 also includes a zoom drive linear module 43 mounted on the base 1 and moving horizontally in the left-right direction. The drive end of each zoom drive linear module 43 is connected to the corresponding camera mounting base 41.

[0028] In addition, such as Figure 1 As shown, the base 1 is equipped with an electrical control box 5. The pressing drive cylinder 23, the slide drive component, each automatic foot alignment component 3, each CCD industrial camera 42 and each zoom drive linear module 43 are electrically connected to the electrical control box 5.

[0029] The following is a detailed description of the new flatness straightening machine in Embodiment 1, with reference to its specific working process. The working process includes the following steps: Step a: The slide drive unit drives the horizontal slide 24 to move forward so that the horizontal slide 24 moves forward to the upper and lower parts station. At this time, the worker places the surface mount electronic components to be processed on the lower mold 21 of the fixture. Step b: The slide drive unit drives the horizontal slide 24 to move backward, so that the lower mold 21 of the fixture loaded with the surface mount electronic components moves backward to the measuring foot position, and so that the lower mold 21 of the fixture moves backward to directly below the upper mold 22 of the fixture. Step c: The clamping drive cylinder 23 is activated and drives the upper mold 22 of the fixture to move down, so that the upper mold 22 and the lower mold 21 of the fixture are closed. At this time, the surface mount electronic components are clamped and fixed between the upper mold 22 and the lower mold 21 of the fixture, so as to realize the clamping and fixing of the surface mount electronic components before measurement. Step d: The CCD industrial camera 42 of each CCD vision inspection component 4 acquires pin images of the corresponding side of the surface mount electronic component and sends the pin images to the control box 5. The control box 5 analyzes and processes the above images to determine whether there is unevenness in the pins of the surface mount electronic component. Step d: If the pins of the surface mount electronic component are determined to be good after inspection by the CCD vision inspection component 4, the automatic pin straightening component 3 on the corresponding side will not perform subsequent pin straightening actions; when the pins of the surface mount electronic component are determined to be defective after inspection by the CCD vision inspection component 4 and the pins are uneven, the control box 5 controls the automatic pin straightening component 3 on the side of the uneven pins to perform pin straightening processing through the automatic pin straightening component 3. Step e: After the automatic lead alignment component 3 completes the lead alignment action, the automatic lead alignment component 3 resets to the initial position. Then, the CCD vision inspection component 4 re-inspects the surface mount electronic components after lead alignment to determine whether the surface mount electronic components are good products. If the surface mount electronic components are still judged to be defective after re-inspection, step de is repeated until the surface mount electronic components are good products. Step f: The clamping drive cylinder 23 drives the upper mold 22 of the fixture to move upward; Step g: The slide drive unit drives the horizontal slide 24 to move forward to the upper and lower parts station. The worker removes the surface mount electronic component that has been processed by the foot trimming from the lower mold 21 of the fixture and places the surface mount electronic component to be processed by the foot trimming on the lower mold 21 of the fixture. Step h: Repeat step ag above to complete the subsequent surface mount electronic component lead finishing process.

[0030] For the CCD vision inspection component 4 in this embodiment, the CCD industrial camera 42 is driven by the zoom drive linear module 43 to achieve horizontal movement to realize the zoom and focus adjustment action of the CCD industrial camera 42.

[0031] It should be emphasized that in this embodiment, the product fixing fixture assembly 2 drives the horizontal slide 24 to reciprocate between the upper and lower workstation and the measuring and aligning workstation via the slide drive component, and the two automatic aligning components 3 and the two CCD vision inspection components 4 are arranged facing each other on the left and right sides of the product fixing fixture assembly 2; compared with the prior art, this structural design has the advantage of good structural compactness.

[0032] It should be further emphasized that the CCD vision inspection component 4 in this embodiment is located at the measurement and alignment station of the horizontal slide 24. The CCD vision inspection component 4 is used to complete the inspection before alignment and the re-measurement after alignment. Compared with the prior art, the structure of the new flatness alignment machine in this embodiment is simpler and the manufacturing cost is lower.

[0033] In summary, the novel flatness straightening machine of this embodiment has the advantages of novel design, compact structure and low manufacturing cost through the above structural design.

[0034] Example 2, as Figures 1 to 4 As shown, the difference between this embodiment 2 and embodiment 1 is that the automatic foot alignment component 3 includes a foot alignment mounting bracket 31 mounted on the base 1 and located above the CCD vision inspection component 4 on the corresponding side. The upper end of the foot alignment mounting bracket 31 is equipped with a horizontal drive linear module 32 that moves horizontally in the front-back direction. The drive end of the horizontal drive linear module 32 is equipped with a horizontal movable seat 33. The horizontal movable seat 33 is equipped with a vertically moving lifting drive linear module 34. The drive end of the lifting drive linear module 34 is equipped with a lifting movable seat 35. The lifting movable seat 35 is equipped with a pin bending block 36.

[0035] Specifically, such as Figure 4 As shown, the needle bending block 36 is provided with an upper bending arm 361 and a lower bending arm 362 located directly below the upper bending arm 361. The upper bending arm 361 and the lower bending arm 362 are vertically aligned, and an anti-cavity groove 363 is formed between the upper bending arm 361 and the lower bending arm 362.

[0036] In the process of leveling the pins of surface mount electronic components by the automatic leveling component in this embodiment 2, the horizontal drive linear module 32 is used to drive the pin bending block 36 to move horizontally back and forth, so that the pin bending block 36 moves to the uneven pin position; the lifting drive linear module 34 is used to drive the pin bending block 36 to move up and down, so that the pin bending block 36 levels the pin by bending up and down.

[0037] It should be noted that during the lifting and lowering process of the linear module 34 driving the pin moving block 36, the pins of the surface mount electronic components are located in the clearance groove 363. When the uneven pins are tilted upwards, the linear module 34 drives the pin moving block to move downwards so as to press the pins downwards through the upper moving arm 361. When the uneven pins are bent downwards, the linear module 34 drives the pin moving block to move upwards so as to push the pins upwards through the lower moving arm 362.

[0038] Example 3, as Figure 1 As shown, the difference between this embodiment 3 and embodiment 1 is that: the base 1 is equipped with two start buttons 6 arranged at left and right intervals, and each start button 6 is electrically connected to the electrical control box 5.

[0039] After the workers place the surface-mount electronic components to be processed into the lower mold 21 of the fixture, they press the start button 6 on the corresponding side with their left and right hands respectively to start the device.

[0040] This dual-start button design effectively improves the safety of staff operation.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
