[0050] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and implementation manners. It can be understood that the specific implementation manners described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the convenience of description, only the parts related to the present disclosure are shown in the drawings.
[0051] It should be noted that, without conflict, the implementation manners in the present disclosure and the features in the implementation manners can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the implementation manners.
[0052] Unless otherwise specified, the exemplary implementation manners / embodiments shown will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various implementation manners / embodiments can be additionally combined, separated, interchanged, and / or rearranged.
[0053] In the drawings, hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of hatching or shading does not convey or imply any preference or requirement for the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for the purpose of clarity and / or description, the dimensions and relative dimensions of the components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences can be performed in an order different from that described. For example, two consecutively described processes can be performed substantially simultaneously or in an order opposite to that described. Additionally, the same reference numerals denote the same components.
[0054] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there can be an intermediate component. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connection" can refer to a physical connection, an electrical connection, etc., and can have or not have an intermediate component.
[0055] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "upon", "higher", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawing is flipped, the component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.
[0056] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. In addition, when the terms "comprises" and / or "comprising" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, so they are used to explain the inherent deviations of measured values, calculated values, and / or provided values that would be recognized by those of ordinary skill in the art.
[0057] Figure 1 is a schematic structural view of a workpiece positioning jig 100 according to an embodiment of the present disclosure. Figure 2 is a schematic structural view of the workpiece positioning jig 100 from another angle according to an embodiment of the present disclosure.
[0058] As Figure 1 and Figure 2 shown, the workpiece positioning jig 100 of the present disclosure can position a workpiece during use. Among them, the workpiece can be a camera assembly (camera module), and the camera assembly includes a camera and a flexible cable. More specifically, the workpiece positioning jig 100 can position the camera of the camera assembly and make the flexible cable located outside the workpiece positioning jig 100 to facilitate the workpiece bending device to bend the flexible cable.
[0059] The workpiece positioning fixture 100 may include components such as a positioning block 110, a first positioning component 120, a second positioning component 130, and a driving device 140.
[0060] Figure 3 It is a schematic structural view of a positioning block according to an embodiment of the present disclosure. Figure 4 It is a schematic structural view of the positioning block from another angle according to an embodiment of the present disclosure.
[0061] The positioning block 110 of the present disclosure can be connected to other components of the production line through a support frame, whereby the positioning block 110 can be set at a preset position.
[0062] The positioning block 110 includes a positioning area, and the positioning area includes a first positioning surface 111 and a second positioning surface 112; preferably, the positioning area is located at a corner of the positioning block 110, so that while positioning the camera, the cable can be located outside the positioning block 110.
[0063] Specifically, the positioning area includes a positioning groove. Considering that the camera of the present disclosure is square, correspondingly, the positioning groove is also set as a square groove, and the cross-sectional dimension of the positioning groove is slightly larger than the size of the camera; and the depth of the positioning groove is less than the depth of the camera, so that at least part of the camera (workpiece) can be located in the positioning groove, and the camera has a movement margin close to the first positioning surface 111 and also has a movement margin close to the second positioning surface 112.
[0064] That is to say, when the camera is placed in the initial state in the positioning groove, there is a certain gap or contact setting between one side wall of the camera and the first positioning surface 111; there is also a certain gap or contact setting between the other side wall of the camera and the second positioning surface 112.
[0065] The positioning groove includes four side walls, wherein the first positioning surface 111 and the second positioning surface 112 are side walls of the square groove, and the first positioning surface 111 and the second positioning surface 112 are adjacent.
[0066] In the present disclosure, the positioning block 110 is provided with receiving grooves 113. The number of the receiving grooves 113 is two, and the two receiving grooves 113 are respectively communicated with the other two side walls of the positioning groove. Correspondingly, in the state where the camera is positioned, at least part of the first positioning portion 122 of the first positioning component 120 can be located in the receiving groove 113, and at least part of the first positioning portion 122 is located in the positioning groove.
[0067] A stop block 114 is arranged in the receiving groove 113. In the present disclosure, the stop block 114 can be integrally formed with the positioning block 110.
[0068] In the present disclosure, the first positioning component 120 and the second positioning component 130 have the same structure. Among them, the first positioning component 120 is rotatably arranged on the positioning block 110. When the first positioning component 120 rotates, at least part of the first positioning component 120 can approach or move away from the workpiece. Similarly, the second positioning component 130 is rotatably arranged on the positioning block 110. When the second positioning component 130 rotates, at least part of the second positioning component 130 can approach or move away from the workpiece.
[0069] The driving device 140 is used to drive the first positioning component 120 and the second positioning component 130. In the present disclosure, two driving devices 140 can be provided. Thus, one driving device 140 drives the first positioning component 120 to act, and the other driving device 140 drives the second positioning component 130 to act. In a preferred embodiment, the number of driving devices 140 is one, which may include a driving cylinder 141 and a driving plate 142 mounted on the driving cylinder 141. When the driving cylinder 141 acts, the driving plate 142 can generate a lifting motion.
[0070] Specifically, the driving device 140 can make the first positioning component 120 and the second positioning component 130 approach the workpiece synchronously or move away from the workpiece synchronously. Thus, when the first positioning component 120 and the second positioning component 130 approach the workpiece, the first positioning component 120 cooperates with the first positioning surface 111, and the second positioning component 130 cooperates with the second positioning surface 112 to position the workpiece. When the first positioning component 120 and the second positioning component 130 move away from the workpiece, the workpiece is released.
[0071] Figure 5 It is a schematic structural diagram of the first positioning component and the second positioning component according to an embodiment of the present disclosure.
[0072] The present disclosure takes the first positioning component 120 as an example to illustrate the structures of the first positioning component 120 and the second positioning component 130.
[0073] The first positioning component 120 includes components such as a base 121 and a first positioning portion 122. Among them, at least part of the base 121 is located in the receiving groove 113, and the base 121 is rotatably arranged on the positioning block 110 through a rotating shaft.
[0074] One end of the first positioning portion 122 is connected to the upper end of the base 121. Among them, when the first positioning component 120 rotates and makes the first positioning component 120 approach the workpiece, the other end of the first positioning portion 122 is used to cooperate with the side wall of the workpiece to position the workpiece.
[0075] In the present disclosure, the first positioning assembly 120 further includes: a limiting portion 123, which is disposed at the lower end of the base portion 121, and the limiting portion 123 is used to limit the maximum position of the first positioning portion 122 away from the workpiece.
[0076] The stopper 114 is located in the area between the first positioning portion 122 and the limiting portion 123. Thus, the limiting portion 123 can cooperate with the stopper 114 and make the first positioning portion 122 in the maximum position away from the workpiece.
[0077] The first positioning assembly 120 further includes: a return spring 124. One end of the return spring 124 abuts against the stopper 114, and the other end abuts against the limiting portion 123. Wherein, the return spring 124 is in a pre-compressed state. Thus, the return spring 124 can apply a thrust force to the limiting portion 123, so as to make the first positioning portion 122 move in the direction approaching the workpiece.
[0078] A ejector rod 125 is provided on the limiting portion 123, and at least a part of the ejector rod 125 extends below the positioning block 110.
[0079] When the workpiece positioning jig 100 of the present disclosure is in use, the driving cylinder 141 acts, the driving plate 142 rises, the driving plate 142 contacts the lower end of the ejector rod 125, and pushes the ejector rod 125 to move upward. Thus, the base portion 121 generates a clockwise rotation. At this time, the first positioning portion 122 is driven to a position away from the workpiece, that is, the first positioning assembly 120 is in a position away from the workpiece, and the workpiece positioning jig 100 is in an open state. In this state, the camera assembly that has completed the bending process can be removed and the next camera assembly can be placed into the positioning groove of the positioning block 110.
[0080] During the opening process of the workpiece positioning jig 100, the limiting portion 123 presses the stopper 114 through the return spring 124. When the return spring 124 cannot be further compressed, the first positioning portion 122 is in the maximum position in the clockwise direction.
[0081] Of course, not every time during the opening process, the first positioning portion 122 is driven to the maximum position in the clockwise direction.
[0082] After the camera module is placed into the positioning slot of the positioning block 110, the driving cylinder 141 stops operating, and at this time, the driving plate 142 descends; under the action of the return spring 124, the base 121 will rotate clockwise. At this time, the free end of the first positioning portion 122 will contact the side wall of the workpiece (camera). At this time, the first positioning portion 122 is not in a horizontal state. Then, driven by the return spring 124, the base 121 continues to rotate counterclockwise, thereby pushing the camera to slide within the positioning slot and approach the first positioning surface, so as to position the camera through the first positioning surface. In this state, the first positioning portion 122 still does not reach the horizontal state. Correspondingly, the base 121 still has a tendency to rotate counterclockwise. Thus, the position of the camera can be fixed by the pressured contact between the first positioning portion 122 and the side wall of the camera. Preferably, in the state where the camera is positioned, the return spring 124 can provide an elastic force of approximately 5 N, thereby ensuring that the workpiece can be clamped in the XY directions while ensuring that the product will not be damaged by clamping. The working process of the second positioning assembly 130 is the same as that of the first positioning assembly 120, and the present disclosure will not elaborate on this one by one.
[0083] The workpiece positioning fixture 100 of the present disclosure may further include a rotary pressing cylinder 150. A pressing arm 160 is mounted on the rotary pressing cylinder 150. After the camera is positioned, the rotary pressing cylinder 150 can be started, and the camera can be pressed tightly through the pressing arm 160 to prevent the position from changing during the process of bending the cable.
[0084] Correspondingly, after the cable is bent, the rotary pressing cylinder 150 is started. The pressing arm 160 first rises a preset distance and then rotates a preset angle (for example, rotates 90°), realizing the release and position avoidance of the workpiece.
[0085] Based on the above structure, the workpiece positioning fixture 100 of the present disclosure can be automatically opened, automatically clamped after the camera is placed, ensuring that the position of the cable will not change during the bending process and ensuring the accuracy of cable bending.
