Description

Technical Field

[0001] This utility model relates to the field of flip structure technology, specifically, to a flip structure. Background Technology

[0002] With the expansion of market demand and production scale for electronic products, such as 5G communications, computers, mobile phones, and wearable electronic devices, the demand for testing flexible circuit boards in electronic products during the production process is increasing rapidly, and the types of testing are numerous.

[0003] Furthermore, with the development of electronic products, the number of components integrated on flexible circuit boards has increased dramatically, such as chips, sensors, and buttons. During the production process, it is necessary to test whether these components on the integrated flexible circuit boards are functioning properly.

[0004] Since the orientation of the flexible circuit board being tested is usually determined according to customer requirements, the following problem arises: if the incoming material (flexible circuit board) orientation is different from the test orientation, especially when the orientation is opposite, it will bring great challenges to the test (for example, the test contacts may not be able to align smoothly), resulting in a significant decrease in the test success rate. Summary of the Invention

[0005] This invention proposes a flipping structure to solve the aforementioned problems.

[0006] The technical solution of this utility model is as follows:

[0007] A flipping structure includes a vision acquisition module, a flipping module, and a receiving module, wherein the vision acquisition module, the flipping module, and the receiving module are arranged sequentially.

[0008] The flipping module includes a flipping bracket, a servo speed reducer, a transmission component, and a material flipping component. The servo speed reducer is mounted on the flipping bracket and drives the material flipping component to flip to the upper part of the receiving module through the transmission component.

[0009] Furthermore, the transmission assembly is a synchronous belt mechanism, and includes a main synchronous pulley, a secondary synchronous pulley, and a synchronous belt. The main synchronous pulley is mounted on the output shaft of the servo reduction drive and is linked to it.

[0010] The material turning assembly includes a turning shaft, from which a synchronous pulley is mounted and linked;

[0011] The synchronous belt is fitted onto the main synchronous pulley and the driven synchronous pulley.

[0012] Furthermore, the flipping bracket is equipped with a slotted photoelectric switch, and the main synchronous pulley is equipped with a light-shielding plate that cooperates with the slotted photoelectric switch.

[0013] Furthermore, the flipping bracket is equipped with a lifting cylinder, and the material flipping assembly includes a flipping carrier plate and a lifting plate, which are elastically connected to the flipping carrier plate.

[0014] The output shaft of the lifting cylinder is fixedly connected to the lifting plate, and after the material flipping component flips, the movement direction of the output shaft of the lifting cylinder is perpendicular to the receiving surface of the receiving module.

[0015] Furthermore, the lifting plate is provided with several limiting posts that are slidably connected to the tilting plate. The tilting plate has a positioning groove for placing materials on the side facing away from the lifting plate. The lifting plate is provided with a feeding pin that can pass through the bottom of the positioning groove and extend into the positioning groove. A floating spring is provided between the lifting plate and the tilting plate.

[0016] Furthermore, the visual acquisition module includes a module bracket, and a shooting component and a light source mounted on the module bracket;

[0017] Furthermore, the shooting direction of the shooting component is the bottom of the material flipping component.

[0018] Furthermore, the receiving module is located on one side of the flipping module and includes a receiving carrier plate, an adjusting plate, a fixing plate, and a base plate;

[0019] The adjusting plate is mounted on the base plate via a support column. The receiving plate is provided with a positioning pin for adjusting its distance from the adjusting plate. The free end of the positioning pin is slidably connected to the adjusting plate. The fixing plate has a slotted hole. One end of the fixing plate is fixedly connected to the receiving plate, and the other end of the fixing plate is fixedly connected to the adjusting plate via the slotted hole and fasteners provided on the slotted hole.

[0020] Furthermore, the tilting shaft is mounted on the lifting plate.

[0021] Furthermore, the surface of the flipping carrier plate is provided with positioning posts, and the receiving module is provided with positioning holes for the positioning posts to pass through.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. This utility model uses a servo motor and a reducer transmission assembly to drive the material turning assembly to turn, and works with automated equipment to achieve automatic feeding, turning, and automatic unloading;

[0024] When the direction of the incoming material from the customer is different from, or mainly opposite to, the orientation of the material under test (such as a flexible circuit board) can be changed by flipping the flipping component, so that the orientation of the material under test conforms to the testing direction of the existing test fixture in the production line, and can be smoothly connected with the test fixture or related testing equipment, thus ensuring the success rate of the test.

[0025] 2. By flipping the material being tested to meet the testing requirements, the redesign of the test fixture can be avoided, or the adjustment range of the test fixture can be reduced, thereby reducing production costs.

[0026] 3. The previous structure of using a rotary cylinder for flipping has been changed, which solves the problem of insufficient debugging space. The flipping angle can also be controlled by a PLC through a touch screen.

[0027] 4. Through its compact structural design and layout, the problem of insufficient space for traditional rotary cylinders due to limited space has been solved.

[0028] 5. By flipping the material under test using this utility model, the orientation of the B2B connector can be changed, such as making it face downwards, thereby improving the stability of the test. Attached Figure Description

[0037] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1

[0039] like Figure 1-6 As shown, a flipping structure is applicable, but not limited to, FPC production lines, especially in situations where customer material delivery and testing directions differ based on project development needs. As a new flipping station, it can work with automated equipment to achieve automatic material loading followed by flipping, as well as automatic material unloading. The main structure includes a vision acquisition module, a flipping module, and a receiving module, which are arranged sequentially.

[0040] Specifically, the flipping module in this embodiment includes a flipping bracket 11, a servo reducer driver 12, a transmission component and a material flipping component. The servo reducer driver 12 is composed of a servo motor and a reducer mounted on the output shaft of the servo motor. It is mounted on the flipping bracket 11 and drives the material flipping component to flip to the upper part of the receiving module through the transmission component.

[0041] In this embodiment, the transmission component preferably adopts a synchronous belt mechanism, which has the advantages of smooth transmission, low noise, and accurate positioning. It includes a main synchronous pulley 131, a secondary synchronous pulley 133, and a synchronous belt 132. The main synchronous pulley 131 is fixedly installed on the output shaft of the servo reducer 12 and linked with it, so that the servo reducer 12 can drive the flipping bracket 11 and the material flipping component to rotate.

[0042] The material flipping assembly in this embodiment includes a flipping shaft 14, which is mounted on and fixedly connected to a lifting plate 152. One side of the lifting plate 152 has a protruding design to connect the flipping shaft 14, facilitating flipping to a designated position and avoiding interference with other structures. Then, a driven synchronous pulley 133 is fixedly mounted to the flipping shaft 14 and linked with it. A synchronous belt 132 is sleeved on the main synchronous pulley 131 and the driven synchronous pulley 133, forming a transmission pair. This allows the flipping shaft 14 and the lifting plate 152 to rotate when the driven synchronous pulley 133 rotates.

[0043] The flipping bracket 11 is also equipped with a slotted photoelectric switch 141 (or a U-shaped photoelectric switch), and a light-shielding plate 142 that cooperates with the slotted photoelectric switch 141 is set on the main synchronous pulley 131. The light-shielding plate 142 is driven to rotate by the main synchronous pulley 131. The slotted photoelectric switch 141 collects intermittent or periodic photoelectric signals to monitor and control the movement of the material flipping component. The light-shielding plate 142 in this embodiment is different from the traditional light-shielding plate 142. The traditional light-shielding plate 142 is very narrow and can only play the role of origin positioning. The light-shielding plate 142 in this embodiment is made into a fan-shaped sheet structure with a projection surface and a central angle of 60°. When the flipping carrier plate 151 needs to move to a negative value other than zero, the light-shielding plate 142 can also block the movement, increasing the movement range of the flipping carrier plate 151 and facilitating debugging.

[0044] To facilitate material unloading, a lifting cylinder 16 is provided on the flipping bracket 11 in this embodiment. In addition, the material flipping assembly also includes a flipping carrier plate 151 and a lifting plate 152, which are elastically connected to the flipping carrier plate 151.

[0045] The output shaft of the lifting cylinder 16 is fixedly connected to the lifting plate 152 via a bearing or similar rotating component. This bearing or similar rotating component is rotatably connected to the tilting shaft 14. In this embodiment, the lifting cylinder 16 is installed at the lower part of the tilting shaft 14, so that when the output shaft of the lifting cylinder 16 retracts downwards, it can drive the lifting plate 152 to move downwards. Furthermore, to improve the smooth operation of the bearing or similar rotating component, it can be slidably connected to the tilting bracket 11 via a sliding groove structure. After the material tilting assembly tilts, the direction of movement of the output shaft of the lifting cylinder 16 is perpendicular to the receiving surface of the receiving module.

[0046] Furthermore, to maintain the relative position of the lifting plate 152 and the tilting carrier plate 151 during elastic floating, this embodiment provides several limiting posts 156 on the lifting plate 152 that are slidably connected to the tilting carrier plate 151. The free ends of the limiting posts 156 pass through limiting holes on the tilting carrier plate 151. The tilting carrier plate 151 has a positioning groove 154 for placing material (FPC) on the side facing away from the lifting plate 152. At the same time, the lifting plate 152 also has one or more feeding pins 155. The feeding pins 155 can pass through the bottom of the positioning groove 154 and extend into the positioning groove 154. Each feeding pin 155 can also be provided with a feeding plate. When feeding, the force of each feeding pin 155 is evenly transmitted to the FPC or other material in the positioning groove 154 by the feeding plate. This is especially suitable for soft materials, ensuring the accuracy and success rate of feeding.

[0047] In order to achieve an elastic (floating) connection between the lifting plate 152 and the flipping carrier plate 151, and to allow the auxiliary lifting cylinder 16 to drive the lifting plate 152 to reset after unloading, this embodiment provides several floating springs 153 between the lifting plate 152 and the flipping carrier plate 151 to improve the stability of the cooperation between the lifting plate 152 and the flipping carrier plate 151.

[0048] Example 2

[0049] Based on Embodiment 1, the visual acquisition module in this embodiment specifically includes a module bracket 21, and a shooting component 23 and a light source 22 mounted on the module bracket 21. The shooting component 23 in this embodiment mainly includes a camera and a lens. Through cooperation with the supplementary light source 22, it has strong compatibility and can scan QR codes on different PFC flexible boards of customers. The scannable QR codes include paper QR codes, laser QR codes on steel sheets, and ink QR codes.

[0050] Since the flip carrier 151 is located above the camera by default, the camera should be pointing towards the bottom of the material flipping assembly and collect data through the opening at the bottom of the positioning slot 154.

[0051] In this embodiment, the light source 22 can be a supplementary lighting device with a reflector, which can not only provide supplementary lighting, but also place the light source 22 on one side of the lens to provide supplementary lighting through reflection, thereby reducing the vertical space occupied. This embodiment will not be described in detail.

[0052] Example 3

[0053] Based on the above embodiments, the receiving module in this embodiment is located on one side of the flipping module and mainly includes a receiving carrier plate 31, an adjusting plate 32, a fixing plate 33 and a base plate 34.

[0054] Specifically, in this embodiment, the adjusting plate 32 is mounted on the base plate 34 via a support column 35. The receiving plate 31 is provided with a positioning pin 36 for adjusting its distance from the adjusting plate 32. The free end of the positioning pin 36 is slidably connected to the adjusting plate 32, allowing the distance between the receiving plate 31 and the adjusting plate 32 to be adjusted during installation. The fixing plate 33 has a slotted hole 331. One end of the fixing plate 33 is fixedly connected to the receiving plate 31, and the other end is fixedly connected to the adjusting plate 32 via the slotted hole 331 and fasteners provided in the slotted hole 331. The position of the fasteners in the slotted hole 331 is adjusted according to the different distances between the receiving plate 31 and the adjusting plate 32, and then tightened. To improve the stability between the receiving plate 31 and the adjusting plate 32, several sets of fixing plates 33 can be provided in this embodiment.

[0055] With the above settings, the receiving plate 31 in this embodiment can adjust its distance (or height) relative to the base plate 34 according to the material feeding height. The adjustment method is as follows: after determining the material feeding height, manually adjust the height of the receiving plate 31 to a suitable position, and then lock the fixing block with screws to ensure that the material feeding height is consistent each time and to ensure the stability of the material feeding.

[0056] In addition, in order to improve the stability of the relative position of the flipping carrier plate 151 and the receiving carrier plate 31 when they are engaged, this embodiment provides a positioning post 157 on the surface of the flipping carrier plate 151 and a positioning hole 311 on the receiving module (specifically the receiving carrier plate 31) for the positioning post 157 to pass through. After the flipping carrier plate 151 is flipped, the relative position of the flipping carrier plate 151 and the receiving carrier plate 31 is locked by the engagement of the positioning post 157 and the positioning hole 311 (or it can be designed as a groove structure).

[0057] The above embodiments are mainly applied to the automated production of FPCs in industries such as 5G communication, chips, modules, and complete machines, and can also be applied to other related parts processing fields.

[0058] It is especially suitable for automated loading and unloading equipment. The specific working process is as follows:

[0059] 1. First, the loading robot loads the PFC flexible board into the material flipping component. Before flipping, the camera scans the code on the FPC flexible board so that the test data corresponds to the tested PFC flexible board.

[0060] 2. After successful scanning, the servo motor drives the flipping shaft 14 to rotate through the servo reduction driver 12, and at the same time drives the material flipping assembly (flipping carrier plate 151 and lifting plate 152) to flip.

[0061] 3. When the flipping carrier plate 151 flips to above the receiving carrier plate 31, the output shaft of the lifting cylinder 16 descends, driving the lifting plate 152 to press down on the flipping carrier plate 151. At this time, since the flipping carrier plate 151 is blocked by the receiving carrier plate 31, the distance between the lifting plate 152 and the flipping carrier plate 151 decreases, thereby driving the feeding pin 155 to feed the PFC soft board from the material flipping assembly onto the receiving carrier plate 31.

[0062] 4. After successful feeding, the material flipping component flips back to wait for the next piece of material to be flipped. At the same time, the lifting cylinder 16 resets (because during the feeding process, the synchronous belt pulley 133 will move downward with the lifting plate 152, and the synchronous belt 132 will become slightly loose. When the lifting cylinder 16 resets, the synchronous belt 132 will return to the tensioned state).

[0063] 5. The PFC flexible board on the receiving carrier plate 31 is removed by the unloading robot on the production equipment;

[0064] 6. This completes the entire process and the next cycle begins.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
