Description

Technical Field

[0001] The present application relates to the technical field of electronic product production and manufacturing, and in particular to a flipping device and processing equipment. Background Art

[0002] Most electronic product components are in sheet form. During production, they often need to be processed on both sides. After processing on one side is completed, the component needs to be flipped over to process the other side.

[0003] For example, when double-sided film is applied to glass, the Z-axis height (the direction of the flip mechanism's lifting) of the product during the flip mechanism's material removal process is inconsistent with the Z-axis height of the product after flipping. This is partly due to the height difference caused by the suction cup assembly (the height difference between the suction cup, suction plate, and the thickness of the glass itself after flipping). In this case, the flip mechanism or material transfer mechanism needs to achieve multi-point positioning on the Z-axis, that is, multi-point positioning at height, to ensure normal material removal.

[0004] In the existing technology, multi-point positioning of the Z-axis is usually achieved through a motor plus a screw, or through a synchronous belt plus a guide rail / guide rod. Such a structure is complex, occupies a large space, and is costly. For the entire line machine, the space that can accommodate the flip mechanism is relatively small, so these mechanisms are not very suitable for small spaces. Utility Model Content

[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0042] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0043] In order to solve the technical problems of complex structure and high cost of the flipping device of the sheet component assembly equipment in the prior art, the present application provides a flipping device that can realize the flipping of sheet components and achieve multi-point positioning after flipping.

[0044] The flipping device of the present application can be used in processes that require flipping during the processing of sheet components of electronic products. The embodiment of the present application is explained by taking the double-sided film of the glass cover plate in the electronic product that needs to be flipped as an example.

[0045] Figure 1 A flipping device is provided in an embodiment of the present application. Figure 2 The figure shows a specific application scenario of the flip device, which is used to flip and position the glass at multiple points in height in the glass assembly equipment to achieve double-sided film lamination of the glass. The glass is usually the screen glass on electronic devices, such as mobile phones, tablets, and various smart handheld terminals or non-handheld terminals with screens.

[0046] The flipping device provided in the embodiment of the present application includes: a flipping mechanism 2, including a flipping drive device 21, a flipping shaft 22 connected to the output shaft of the flipping drive device 21, and a material picking assembly 23 connected to the flipping shaft 22, wherein the height of the material picking surface of the material picking assembly 23 when facing downward is lower than the height when facing upward; a single-stroke lifting cylinder 3, having a cylinder body 30 and a cylinder rod 31, and the cylinder rod 31 is driven and connected to the flipping mechanism 2; a limit member 4, arranged on the lifting path of the flipping mechanism 2.

[0047] like Figure 3As shown, the material picking component 23 of the flipping mechanism 2 in the embodiment of the present application has a material picking surface. Before flipping, the material picking surface faces downward and is used to pick up materials from the material picking position. After flipping, the material picking surface faces upward and is used to connect with the unloading module at the feeding position to pick up the workpiece from the material picking surface and transfer it to the next workstation. The flipping mechanism is flipped when the height remains unchanged. The height of the material picking surface before flipping is lower than the height of the material picking surface after flipping, and the height difference is X. In this embodiment, the single-stroke lifting cylinder 3 is mainly used to lift the flipping mechanism 2 to compensate for the height difference formed during the flipping process. The flipping mechanism 2 is connected to the cylinder rod 31 of the single-stroke lifting cylinder 3. The cylinder rod 31 in the single-stroke lifting cylinder 3 extends and retracts relative to the cylinder body 30 in the vertical lifting direction, and will not occupy a large space in the width direction of the cylinder, which is beneficial to the optimization of the space occupied by the entire flipping device in the horizontal direction. Reference Figure 2 As shown, the turning device is mainly arranged on both sides of the glass assembly equipment, and adopts a single-stroke lifting cylinder 3. When the cylinder structure itself is narrow, compact installation can be achieved, ensuring the width control of the entire device.

[0048] In this embodiment, since the single-stroke lifting cylinder 3 has only one stroke, when the cylinder rod 31 is in the maximum position and the minimum position during extension and contraction, the flipping mechanism 2 is correspondingly in the highest height position H1 and the lowest height position H2. By setting a limiter 4 on the lifting path of the flipping mechanism 2, the control of the third height position, i.e., the material picking height position H3, can be achieved. In this way, the limiter 4 can hard-limit the material picking position of the material picking component 23, so that the material picking surface of the material picking component 23 remains in the same position when it is flipped and then flipped back for picking up the material, thereby avoiding crushing the glass, ensuring the material picking accuracy of the material picking component 23, and reducing the risk of damage during the material picking process.

[0049] The flipping device provided in the embodiment of the present application has a relatively simple structure and occupies a small space. At the same time, it utilizes the highest and lowest positions of the cylinder itself for positioning, and combined with the limit members, it can achieve multi-point positioning of the cylinder along the stroke, thereby achieving the consistency of the height of the workpiece before and after flipping, thereby ensuring accurate material removal.

[0050] It should be noted that the single-stroke lifting cylinder 3 of this embodiment can adopt a dual cylinder rod structure, including two cylinder rods 31 that are arranged side by side and lifted synchronously, which has a more stable stroke output control and can avoid rotation during the output process.

[0051] It should be noted that if the flip device adopts Figure 2 In contrast to the inverted arrangement, a limiter may also be provided during the upward stroke of the flip mechanism 2 , that is, a limiter may be provided on the upper side of the flip shaft 22 .

[0052] It should be noted that the tilting drive device 21 of this embodiment is generally driven by a motor. Generally speaking, the motor drive has a built-in speed reducer. The tilting shaft 22 is connected to the output shaft of the motor drive. The tilting shaft 22 is provided with a connection structure corresponding to the material picking assembly 23. This can be a hard connection method such as a screw connection, a pin connection, or a snap connection. The material picking assembly 23 generally adopts a suction plate structure to achieve suction and picking of materials on smooth surfaces.

[0053] In this embodiment, since the center of gravity of the flipping mechanism does not coincide with the center of vertical lifting of the one-stroke lifting cylinder 3, and the flipping mechanism needs to rotate 180 degrees back and forth to absorb the product, the center of gravity changes. At this time, the one-stroke lifting cylinder 3 is required to be able to withstand the cantilever force caused by the non-coincidence between the center of gravity of the rotating mechanism and the center of the one-stroke lifting cylinder 3. Therefore, a slide assembly 33 is provided on the one-stroke lifting cylinder 3, which is connected to the flipping mechanism 2 through the slide assembly 33 to eliminate the influence of the cantilever force.

[0054] As a specific embodiment, the slide assembly 33 may include a guide rail 331 and a slide 332. The cylinder body 30 of the single-stroke cylinder 3 is fixedly connected to the guide rail 331, the cylinder rod 31 is fixedly connected to the slide 332, and the slide 332 is fixedly connected to the flipping mechanism 2. When the cylinder rod 31 is extended or retracted, the slide 332 is driven to rise and fall, thereby driving the flipping mechanism 2 to rise and fall. The guide rail 331 and the slide 332 themselves are laterally limited to each other, and can well withstand the cantilever force brought by the flipping mechanism.

[0055] Furthermore, the flipping mechanism 2 is fixedly connected to the slide 332 via a connecting plate 32 . The connecting plate 32 extends from the top of the slide 332 , and the flipping mechanism 2 is connected to the portion of the connecting plate 32 extending from the slide 332 .

[0056] The tilting device provided in this embodiment includes a base 1, on which a cylinder 30 and a stopper 4 are mounted. The base 1 primarily supports the cylinder 30 and stopper 4 and is connected to the body or base of the glass assembly equipment. The base 1 may include a bottom plate 11 and a vertical plate 12, with the vertical plate 12 providing mounting points for the single-stroke lift cylinder 3.

[0057] like Figure 3As shown, in this embodiment, the position limiter 4 serves to hard-limit the tilting mechanism 2 during its descent. Therefore, any one of multiple locations of the entire tilting mechanism 2 can be limited, such as the connecting plate 32, the tilting drive device 21, or the material-retrieving assembly 23. To avoid the influence of the cantilever force of the tilting mechanism 2, it is best to limit the location with better rigidity. Therefore, the position limiter 4 of this embodiment is provided corresponding to the position of the tilting shaft 22 to hard-limit the tilting shaft 22, that is, the position limiter 4 is provided on the ascending and descending path of the tilting shaft 22.

[0058] Furthermore, the closer the limit point (the contact point where the limit member 4 abuts the flip shaft 22) is to the connection point between the connecting plate 32 and the flip mechanism 2, the better, which can further reduce the length of the lever arm (the distance from the connection point to the limit point), thereby reducing the impact of the lever arm.

[0059] As a specific embodiment, the two opposite sides of the flip shaft 22 are respectively provided with a limit portion 221 and an avoidance portion 222, the limit portion 221 is oriented in the same direction as the material taking surface, and the limit member 4 corresponds to the position of the limit portion 221 or the avoidance portion 222. Figure 6 After the flip shaft 22 flips, the distance between the bottom of the avoidance portion 222 and the limiter 4 is Z. The flip shaft 22 is controlled by the single-stroke lifting cylinder 3 to descend from the highest height position H1 to the lowest height position H2. The descending height Z1 is less than Z, that is, Z is greater than the stroke of the single-stroke lifting cylinder 3. Through the setting of the avoidance portion 222, the flip mechanism 2 can be prevented from being blocked by the limiter 4 in the process of descending to the feeding position after completing material picking and flipping.

[0060] Of course, in order to ensure that the limit member 4 does not block the flip shaft 22 when the single-stroke lifting cylinder 3 descends to the lowest position, it can be achieved by controlling the movement of the limit member 4. For example, it can be achieved by controlling the limit member 4 to offset its position when the single-stroke lifting cylinder 3 descends to the lowest position to avoid blocking the flip shaft 22. Of course, this will add a mechanism for driving the limit member 4 and a structure for realizing the sliding of the limit member 4, resulting in an increase in the overall cost. The avoidance portion 222 only needs to be structurally designed and implemented on the flip shaft 22, which is a lower-cost implementation method.

[0061] Furthermore, the stopper 221 protrudes from the tilt shaft 22. When the material-retrieving surface of the material-retrieving assembly 23 faces downward, the tilt shaft 22 is provided with a protruding stopper 221 at a position corresponding to the stopper 4. The stopper 221 can be provided with a planar stopper, which can reduce lateral friction during the stoppering process and reduce wear on the stopper surface, thereby ensuring the accuracy of the stoppering.

[0062] Specifically, the avoidance portion 222 of the flip shaft 22 is a recessed area in the opposite direction of the limiting portion 221 of the flip shaft 22. At the same time, the position where the material-picking component 23 is connected to the flip shaft 22 is also in the same plane as the avoidance portion 222, that is, the flip shaft 22 is generally L-shaped in the direction of extension from the flip drive device 21. In this embodiment, the avoidance portion 222 deviates from the rotation axis as a whole, and the material-picking component 23 is arranged on the surface of the avoidance portion 222. Compared with being arranged on the maximum outer diameter of the flip shaft 22, the value of the height difference X can be reduced, and at the same time, the structure of the avoidance limiter 4 can also be formed.

[0063] The flipping device of this embodiment also includes a sensor assembly 5, which can be used to detect the stroke of the cylinder rod 31 to control the material picking assembly 23 to pick up materials, and / or detect the stroke of the cylinder rod 31 to facilitate the material picking of the unloading device 7 when the flipping shaft 22 is at the feeding position height. The setting of the sensor assembly 5 corresponds to the lifting height position setting of the cylinder rod 31.

[0064] As a specific embodiment, the sensor assembly 5 includes: a fixed first limit sensor 51, a fixed second limit sensor 52, and a trigger member 53 linked to the cylinder rod 31. The first limit sensor 51 corresponds to the flip axis 22 being at the material picking level height setting, and the second limit sensor 52 corresponds to the flip axis 22 being at the material feeding level height setting.

[0065] For details, please refer to Figure 1 The first limit sensor 51 and the second limit sensor 52 are respectively arranged on the vertical plate 12. The trigger member 53 linked to the cylinder rod 31 can be arranged on the connecting plate 32, and its trigger end extends to the first limit sensor 51 and the second limit sensor 52. When the flip mechanism 2 descends to pick up materials, it is limited by the limit member 4. When the limit portion 221 abuts the limit member 4, the trigger member 53 just moves to the position of the first limit sensor 51, thereby triggering the first limit sensor 51 to generate a signal, which is sent to the controller to control the picking assembly 23 to pick up materials. Therefore, the position of the first limit sensor 51 corresponds to the picking height when the picking assembly 23 picks up materials. When the flipping mechanism 2 descends, the setting of the avoidance portion 222 will not be blocked by the limit member 4, and the cylinder rod 31 descends to the lowest stroke height H2. The trigger member 53 just moves to the position of the second limit sensor 52, thereby triggering the second limit sensor 52 to generate a signal, which is sent to the controller to control the docking and unloading device to pick up materials from the material picking component 23. Therefore, the position of the second limit sensor 52 corresponds to the feeding height when the material picking component 23 is feeding.

[0066] Based on the above-mentioned flip device, Figure 2 and Figure 5As shown, the present application also provides a processing device, which includes: a feeding platform 6, a turning device and a docking and unloading device 7.

[0067] Among them, the feeding platform 6 is used to transport the workpiece to the flipping device; the flipping device is the flipping device described in the above embodiment, and will not be repeated here. The flipping device is arranged on one side or both sides of the feeding platform 6, and the flipping device is used to take materials from the feeding platform 6 and feed materials to the docking and unloading device 7. The docking and unloading device 7 is set corresponding to the position after the flipping device is flipped, and is used to grab the workpiece after the flipping device is flipped, and send it to the feeding platform 6 for processing on the other side. Due to the multi-point positioning of the flipping device, the height of the workpiece before and after flipping can be kept consistent. Therefore, the docking and unloading device 7 only needs to take and discharge materials at the same height, that is, it can be driven by a cylinder, and there is no need to set up a gantry structure motor and screw drive module, which reduces the space occupancy.

[0068] like Figure 2-5 As shown, when the processing equipment is used to flip and double-sided process the glass, the working process of the glass processing equipment and the flipping device is as follows:

[0069] S1, such as Figure 2 As shown, the feeding platform 6 moves the glass into position, and the picking assembly 23 faces the glass toward the feeding platform 6, as shown in FIG. Figure 1 As shown, the single-stroke lifting cylinder 3 contracts the cylinder rod 31, driving the flip mechanism 2 to move downward, and the limit portion 221 of the flip shaft 22 abuts against the stop portion 41 of the limit member 4. At the same time, the trigger member 53 reaches the position of the first limit sensor 51 and is triggered, and the material taking assembly 23 sucks the glass;

[0070] S2, the single-stroke lifting cylinder 3 extends to the highest position, driving the flip mechanism 2 to move upward, and the flip mechanism 2 flips, turning the glass 180 degrees;

[0071] S3, such as Figure 4 and Figure 5 As shown, after flipping, the single-stroke lifting cylinder 3 moves down to the lowest position. Due to the existence of the avoidance portion 222, the stop portion 41 of the limit member 4 avoids the air. At this time, the trigger member reaches the position of the second limit sensor 52 and is triggered. The docking unloading device 7 takes away the flipped glass and places it on the feeding platform for double-sided film lamination.

[0072] like Figure 6 As shown, Figure 6Schematic diagram of the height change of the turning mechanism of the turning device provided in the embodiment of the present application, H1 corresponds to the highest height position of the turning mechanism 2, H2 corresponds to the lowest height position of the turning mechanism, H3 corresponds to the height position of the turning mechanism 2 when taking materials (limited by the limiter 4), Z is greater than Y, and Z1 is less than Z so that the turning shaft 22 does not hit the limiter 4. Based on the above embodiment and Figure 6 As shown, the position change of the single-stroke lifting cylinder and the movement change of the tilting axis are as follows:

[0073] T1, initial position, the single-stroke lifting cylinder drives the flip shaft 22 to the highest height position H1, the state of the flip shaft 22 at this time is that the material taking surface of the material taking component 23 is facing downward, and the distance between the limit part 221 and the stop part 41 of the limit member 4 is Y;

[0074] T2, the material taking position, when the single-stroke lifting cylinder drives the flip shaft to move downward by a distance Y, the limiting member 4 limits its limiting portion 221, so that the flip shaft 22 is fixed at the material taking height position H3, and the material taking assembly 23 takes the material;

[0075] T3, rising position, after the material is taken, the single-stroke lifting cylinder drives the turning shaft 22 to rise a distance Y to the highest height position H1;

[0076] T4, flip position, at the highest height position H1, the flip drive device 21 drives the flip shaft 22 to flip, so that the avoidance portion 222 of the flip shaft 22 faces the direction of the limit block 4, and the distance between the avoidance portion 222 and the limit block 4 is Z;

[0077] T5, feeding position, the single-stroke lifting cylinder drives the flip shaft 22 to descend to the lowest height position H2, and the avoidance portion 222 is at a distance Z1 from the axis of the flip shaft. Since Z1 is smaller than Z, the limit will not limit the flip shaft 22.

[0078] T6, after the docking feeding is completed, the single-stroke lifting cylinder moves the flip shaft 22 up to the highest height position H1, and flips it to the material-retrieving surface facing downward, and returns to the initial position.
