[0002] In electronic manufacturing, precision assembly, and automated production processes, jigs are key process equipment widely used for the positioning, support, and fixation of workpieces. Especially in assembly, welding, or inspection processes involving multiple hardware components, the performance of jigs directly affects the assembly accuracy, consistency, and production efficiency of products.

[0003] Traditional jigs mostly adopt fixed or semi-fixed structures. Although these structures are simple and low-cost, they suffer from problems such as cumbersome clamping operations and low versatility. However, with the diversification of products, jigs need to adapt to the rapid assembly and precise positioning of hardware of different specifications, which places higher demands on clamping methods, adjustment flexibility, and the ability to coordinate with automated production lines.

[0012] This specification will be further described by way of exemplary embodiments, which will be described in detail with reference to the accompanying drawings. These embodiments are not limiting; in these embodiments, the same reference numerals denote the same structures, wherein: Figure 1 This is a front view of the fixture shown in some embodiments of this specification; Figure 2 This is a top view of the fixture shown in some embodiments of this specification; Figure 3 This is a top view of the fixture plate of the fixture shown in some embodiments of this specification; Figure 4 This is a perspective view of the jig plate of the jig shown in some embodiments of this specification; Figure 5 This is a side view of the fixture plate of the fixture shown in some embodiments of this specification; Figure 6 This is another front view of a fixture according to some embodiments of this specification. Detailed Implementation

[0013] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0014] Unless the context clearly indicates an exception, words such as "a," "an," "a kind," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0015] It should be understood that the terms "first," "second," and similar terms used in this specification do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Unless otherwise stated, terms such as "front," "rear," "lower," and / or "upper" are for illustrative purposes only and are not limited to a location or spatial orientation.

[0016] In automated production lines, robotic arms or processing equipment require precise manipulation of workpieces. If there are even slight deviations in the workpiece's placement each time, the automated equipment may fail to accurately identify and operate it. Therefore, precise workpiece positioning during production is crucial for ensuring the consistency of product size, shape, and function. This specification provides a fixture that can precisely position the workpiece to the same preset position each time, and also allows for rapid changeover through simple adjustments, improving production efficiency.

[0017] Figure 1 This is a front view of the fixture shown in some embodiments of this specification. Figure 2 This is a top view of the fixture shown in some embodiments of this specification.

[0018] In some embodiments, such as Figure 1 As shown, the fixture may include multiple sets of hardware fixing mechanisms 11, fixture plate 12, multiple sets of hardware 13, and two sets of guide rails 14.

[0019] The fitting fixing mechanism 11 is a mechanism used to move or fix the fitting 13.

[0020] In some embodiments, each set of hardware fixing mechanisms 11 includes: a pneumatic pressure clamp 11-1, a slider 11-2, and a first driving device (not shown in the figure).

[0021] In some embodiments, such as Figure 1 , Figure 2 As shown, multiple sets of hardware fixing mechanisms 11 can be respectively disposed on both sides of the jig plate 12. In some embodiments, the hardware fixing mechanisms 11 can be four sets (see...). Figure 2 (It can also be in two groups, six groups, etc., depending on actual needs or the number of hardware 13.)

[0022] The pneumatic pressure clamp 11-1 is a cylinder-driven component for gripping the workpiece 15. In some embodiments, the pneumatic pressure clamp 11-1 may include grippers 21. For example, as... Figure 2 As shown, the gripper 21 is disposed at the end of the pneumatic pressure clamp 11-1. For more details about the gripper, please refer to the relevant description below. In some embodiments, the pneumatic pressure clamp 11-1 is configured to clamp at least one of a plurality of hardware sets 13.

[0023] The slider 11-2 is a structure that can drive the pneumatic pressure clamp 11-1 to slide along the guide rail 14.

[0024] The first driving device is a means for driving the pneumatic pressure clamp 11-1 to move relative to the slider 11-2. In some embodiments, the first driving device may include a telescopic cylinder. In some embodiments, the first driving device drives the pneumatic pressure clamp 11-1 to move along a first direction, which is perpendicular to the length direction of the guide rail 14.

[0025] The fixture plate 12 is a structure used to assist the fittings 13 in positioning or fixing the workpiece 15.

[0026] In some embodiments, the jig plate 12 includes a set of slots (see...). Figure 2 (dashed line portion), multiple sets of fittings 13 can move along the slot relative to the fixture plate 12.

[0027] A groove group is a plurality of recesses used to limit the movement of the fitting 13. In some embodiments, the groove group may include multiple recesses with different shapes, sizes or distributions; see [link to details]. Figure 3 And related explanations.

[0028] Fittings 13 are metal parts used to remove or fix workpieces 15. For example, multiple sets of fittings 13 can clamp and fix workpieces 15 after contact. As another example, when workpieces 15 have process holes, multiple sets of fittings 13 can fix workpieces 15 by engaging with the process holes via connectors 16. In some embodiments, multiple sets of fittings 13 may include fittings with suction cups 43 (see...). Figure 4 , 5 (and as explained below), fixtures, clamps, etc., can be set according to actual needs. Connector 16 is a component used to connect fitting 13 and workpiece 15.

[0029] In some embodiments, the jig plate 12 and the fitting 13 are detachably connected. For example, the jig plate 12 and the fitting 13 can be connected by a nut (see...). Figure 4 , 5(and related explanations below). For example, a buckle can be provided at the end of the fitting 13 facing the jig plate 12, and a protruding structure matching the shape of the buckle can be provided in the groove of the slot group of the jig plate 12. When the fitting 13 is rotated to a certain angle in the groove, the buckle can cooperate with the protruding structure to fix it.

[0030] Guide rail 14 is a track used to guide the movement of the hardware fixing mechanism 11. In some embodiments, guide rail 14 may be fixedly disposed on both sides of fixture plate 12. For example, as Figure 1 , Figure 2 As shown, the guide rails 14 can be symmetrically arranged on both sides of the fixture plate 12.

[0031] In some embodiments, a second driving device (not shown in the figure) may be provided on the pneumatic pressure clamp 11-1 or the guide rail 14. The second driving device is a device for driving the slider 11-2 to slide along the length direction of the guide rail 14. The length direction of the guide rail 14 can be... Figure 2 The Y-axis direction is shown. In some embodiments, the second drive device may include a motor, a lead screw, or a gear, etc.

[0032] Workpiece 15 refers to the part to be processed or assembled.

[0033] In some embodiments, one end of the pneumatic pressure clamp 11-1 is fixed to one end of the slider 11-2, and the other end of the slider 11-2 is slidably connected to the guide rail 14, and the slider 11-2 can move along the length direction of the guide rail 14.

[0034] In some embodiments, the fixture may further include a processor. A processor is a device or component that processes data and generates instructions. For example, a processor may be a central processing unit (CPU), a graphics processing unit (GPU), an application-specific integrated circuit (ASIC), or any combination thereof. Data may come from the aforementioned different components or other data sources. Instructions may be sent to the aforementioned different components. The processor may also include other components related to the above, for example, a processor may also refer to a computer, mobile phone, server, industrial control computer, circuit board with computing functions, etc. In some embodiments, the processor may be disposed on the hardware fixing mechanism 11 or the guide rail 14, or may be disposed at other locations on the fixture as needed. In some embodiments, the processor may be communicatively connected to components such as the pneumatic pressure clamp 11-1, the first drive device, and the second drive device.

[0035] In some embodiments, the processor can acquire the position coordinates of the grippers of the multiple pneumatic pressure clamps 11-1, thereby determining the position of the workpiece 15 after it is fixed by the fixture 13. In some embodiments, the jig plate 12 is fixed relative to the robotic arm or processing equipment, and the processor can automatically determine the theoretical relative position of the workpiece 15 and the jig plate 12 based on the workpiece 15's drawing or 3D model to ensure that the theoretical relative position of the workpiece 15 is correct. Through the first driving device, the second driving device, etc., the actual position of the workpiece can be made consistent with the theoretical relative position, thereby improving the positioning accuracy of the workpiece.

[0036] For example, when it is necessary to re-fix the workpiece 15 and the fitting 13 due to workpiece changeover, technicians or robotic arms can first place the fitting 13 to be fixed in the corresponding groove of the slot group; the step of determining the groove can be completed by the processor, which can automatically determine the corresponding groove and display it according to the size of the workpiece 15 or subsequent processing needs; after the multiple sets of fitting fixing mechanisms 11 clamp the fitting 13, they start to move. After the clamped fitting 13 contacts the workpiece 15, it continues to move until the fitting 13 and the workpiece 15 are pressed together; after the fitting 13 and the workpiece 15 are pressed together, technicians or robotic arms can further fix the fitting 13 firmly with bolts, nuts, etc.

[0037] During the process of placing a workpiece onto a machine tool for machining, it is necessary to determine the relative position of the workpiece and the machine tool. Generally, different workpieces are best located in the same preset position to ensure machining accuracy. When manually adjusting the position of the workpiece and the fixture plate, the final positioning may not be accurate enough. The automated control hardware fixing mechanism and guide rails in some embodiments of this specification allow the processor to obtain the position of the workpiece in two directions through a first drive device and a second drive device, thereby accurately positioning the workpiece. Machining accuracy will not decrease due to inaccurate workpiece positioning.

[0038] Traditional jigs, which use rectangular strips connected by screws for adjustment, can improve turnaround efficiency, but this method is cumbersome and time-consuming. In some embodiments of this specification, a jig comprising multiple sets of hardware fixing mechanisms, a jig plate, multiple sets of hardware, and two sets of guide rails is used. The hardware fixing mechanisms and guide rails allow for adjustment of the hardware positions in multiple directions to change the hardware distribution, achieving rapid automated turnaround and precise positioning.

[0040] Figure 4 This is a perspective view of the fixture plate of the fixture shown in some embodiments of this specification.

[0041] Figure 5 This is a side view of the fixture plate of the fixture shown in some embodiments of this specification.

[0042] In some embodiments, such as Figure 3 As shown, the groove group includes: a first groove group 31, a second groove group 32, a third groove group 33, and a fourth groove group 34; the first groove group 31 includes a plurality of first grooves 31-1, the second groove group 32 includes a plurality of second grooves 32-1; the length of the second grooves 32-1 is less than the length of the first grooves 31-1; the third groove group 33 includes a plurality of third grooves 33-1 arranged in order of length; the angle α between the length direction of the fourth groove group 34 and the length direction of the first groove group 31 is 30°~60°.

[0047] In some embodiments, the second groove group 32 includes a plurality of second grooves 32-1. The plurality of second grooves 32-1 have the same length.

[0048] The plurality of second grooves 32-1 refer to a plurality of strip-shaped grooves extending along the Y-axis direction located in the second groove group 32. In some embodiments, the plurality of second grooves 32-1 may be arranged at intervals along the X-axis direction, and the interval distance between adjacent second grooves 32-1 may be the same or different. In some embodiments, the second groove group 32 formed by the plurality of second grooves 32-1 is symmetrically arranged on both sides of the fixture plate 12 along the X-axis direction.

[0049] In some embodiments, the length of the second groove 32-1 is less than the length of the first groove 31-1. In some embodiments, the length of the second groove 32-1 is less than the spacing between the two first groove groups 31 symmetrically disposed on both sides of the fixture plate 12 along the Y-axis direction.

[0050] The third groove group 33 refers to a group of groove structures located on the fixture plate 12 with different lengths in the X-axis or Y-axis direction.

[0051] In some embodiments, the third groove group 33 includes a plurality of third grooves 33-1.

[0052] The plurality of third grooves 33-1 refer to multiple strip-shaped grooves located in the third groove group 33, arranged along the X-axis or Y-axis direction, and whose lengths change sequentially. In some embodiments, the plurality of third grooves 33-1 may be arranged at intervals along the Y-axis direction and / or along the X-axis direction, and the interval distance between adjacent third grooves 33-1 may be the same or different. In some embodiments, the plurality of third grooves 33-1 arranged at intervals along the same direction may be arranged in order of length from shortest to longest or from longest to shortest. In some embodiments, the plurality of third grooves 33-1 may be symmetrically arranged with a straight line passing through the center of the fixture plate 12 at an angle of 45° to the X-axis as the axis. In some embodiments, the length of each third groove 33-1 in the plurality of third grooves 33-1 is less than the length of the second groove 32-1.

[0053] The fourth groove group 34 refers to a set of groove structures arranged at an angle on the fixture plate 12.

[0054] In some embodiments, the fourth groove group 34 may have one or more grooves. In some embodiments, when the fourth groove group 34 includes multiple grooves, the multiple grooves of the fourth groove group 34 may be arranged at intervals along the X-axis direction, and the interval distance may be the same or different. In some embodiments, one or more grooves of the fourth groove group 34 may be arranged centrally symmetrically based on the center of the fixture plate 12.

[0055] In some embodiments, the angle α between the length direction of the fourth groove group 34 and the length direction of the first groove group 31 is 30° to 60°.

In some embodiments, the angle α between the length direction of the fourth groove group 34 and the length direction of the first groove group 31 can be 30°, 45°, 50°, or 60°.

[0056] It should be noted that, Figure 3 The first slot group 31, the second slot group 32, the third slot group 33, and the fourth slot group 34 are for illustration only and may differ from their actual shape or distribution. The actual shape or distribution of the first slot group 31, the second slot group 32, the third slot group 33, and the fourth slot group 34 can be set as needed.

[0057] In some embodiments, the widths of the multiple grooves in the slot group may be the same. In some embodiments, the widths of the multiple grooves in the slot group may also be different to accommodate fittings of different sizes.

[0058] The position where the fitting 13 connects to the fixture plate 12 can be provided with a nut or other fastener. During the movement of the fitting 13, the nut or other fastener is not tightened. The fitting 13 can slide along the length of the groove in the groove to quickly adjust its position.

[0059] The embodiments in this specification improve the compatibility of the fixture with different products by designing multiple sets of groove combinations with different sizes and layouts. This not only enables rapid production changeover and reduces downtime for debugging, but also significantly reduces the manufacturing and management costs caused by frequent replacement or customization of fixtures, thereby improving production efficiency and equipment utilization.

[0060] In some embodiments, the jig plate 12 is made of aluminum alloy and has a thickness of 3-8 mm. In some embodiments, the thickness of the jig plate 12 may also be 5-8 mm. In some embodiments, the thickness of the jig plate 12 may also be 3-6 mm.

[0061] In some embodiments, the fixture plate 12 may be made of aluminum alloy panel, which may be 5 mm thick and rectangular in shape with dimensions of 250 mm * 250 mm.

[0062] In some embodiments, the aluminum alloy panel can be 6mm thick and have a rectangular shape with dimensions of 255mm x 255mm.

[0063] In some embodiments, the aluminum alloy panel can be 7mm thick and have a rectangular shape with dimensions of 260mm x 260mm.

[0064] Aluminum alloys have the advantages of low density, high strength, corrosion resistance, and ease of processing. The embodiments in this specification use a jig plate made of aluminum alloy, which helps to reduce the overall weight and improve manufacturing efficiency. The thickness is set at 3-8mm, which ensures the structural rigidity and stability of the jig plate during use, prevents deformation under stress from affecting the positioning accuracy, and avoids the increase in weight and difficulty in installation and adjustment due to excessive thickness. It takes into account both strength requirements and ease of operation, which helps to improve assembly efficiency and reliability.

[0065] In some embodiments, such as Figure 4 , Figure 5 As shown, each set of fittings 13 includes a nut 41 and a suction cup 43; the nut 41 is configured to connect the fitting 13 to the fixture plate 12, and the suction cup 43 is configured to pick up the workpiece.

[0066] In some embodiments, each set of hardware includes a nut 41 and a suction cup 43.

[0067] In some embodiments, the fitting 13 can be screwed into a groove in a slot group on the fixture plate 12 by a nut 41. In some embodiments, when the fitting 13 needs to be replaced, a technician or robotic arm can unscrew the nut 41 to replace the fitting 13.

[0068] The suction cup 43 refers to a device that uses air pressure difference to generate suction force to fix the workpiece 15. In some embodiments, the suction force of the suction cup 43 can be provided by a vacuum supply device (e.g., an air pump), and the suction cup 43 is provided with a connector 42 on the side facing the fixture plate 12. In some embodiments, the vacuum supply device can be communicatively connected to a processor.

[0069] The connector 42 is a component used to connect the fitting 13 to the vacuum supply device. In some embodiments, the connector 42 can connect multiple fittings 13 in series and connect the suction cups 43 of the multiple fittings 13 in series to the vacuum supply device.

[0070] In some embodiments, the suction cup 43 may be made of rubber.

[0071] In some embodiments, a nut 41 is disposed on the side of the fitting 13 that contacts the fixture plate 12. A suction cup 43 is mounted on the end of the fitting 13 facing the workpiece 15. After the fitting 13 is fixed to the fixture plate 12 by the nut 41, the suction cup 43 can be aligned with the surface of the workpiece 15 and use suction force to grip or fix the workpiece 15. In some embodiments, the connector 42 of the fitting 13 can be connected to a vacuum supply device. The processor can control the negative pressure on and off of the suction cup 43 of the fitting 13 by controlling the vacuum supply device to release the workpiece 15. During suction, a vacuum is drawn to grip the workpiece, and during release, the negative pressure is cut off or a positive pressure is introduced to detach the workpiece 15 from the suction cup 43.

[0072] The embodiments in this manual use nuts to detachably fix the hardware to the fixture plate. With the help of a suction cup, the workpiece can be picked up. This ensures the stability and positional adjustability of the hardware installation, and also achieves stable gripping and rapid release of the workpiece, improving the reliability and efficiency of the pick-and-place operation. At the same time, it is easy to replace the hardware with a suitable one according to different workpiece shapes, thus enhancing the versatility of the fixture.

[0073] Figure 6 This is another front view of the fixture shown in some embodiments of this specification.

[0074] In some embodiments, such as Figure 6 As shown, each set of hardware fixing mechanisms 11 also includes a rotary drive (not shown in the figure); the rotary drive is configured to drive the pneumatic pressure clamp 11-1 to rotate; the pneumatic pressure clamp 11-1 is also configured to clamp the soft rubber gate 62.

[0075] The rotary drive unit refers to the device used to drive the pneumatic pressure clamp 11-1 to rotate. The rotary drive unit can be the same component as the first drive unit or the second drive unit, only adding the rotation function.

[0076] In some embodiments, the rotary drive can drive the pneumatic pressure clamp 11-1 to rotate via a cylinder. For example, the rotary drive can drive the pneumatic pressure clamp 11-1 to rotate circumferentially about the rotation axis 61. In some embodiments, the rotary drive may include a rotary cylinder.

[0077] In some embodiments, the rotary drive can drive the pneumatic clamp 11-1 to rotate and grip the hardware. For example, when the pneumatic clamp 11-1 cannot grip the hardware perpendicularly due to special workpiece shapes (e.g., the gripping space is insufficient when perpendicular), the rotary drive can drive the pneumatic clamp 11-1 to rotate, so that the pneumatic clamp 11-1 has an angle relative to the hardware. By providing the rotary drive, the pneumatic clamp can adapt to more workpieces with different shapes.

[0078] During the production process, when injection molding is in progress, the soft rubber gate 62 is connected to the workpiece 15. After injection molding, the soft rubber gate 62 needs to be detached from the workpiece 15.

[0079] In some embodiments, the pneumatic pressure clamp 11-1 is also configured to grip the soft rubber gate 62.

[0080] The soft plastic gate 62 refers to the injection port used to inject molten plastic during the soft plastic injection molding process.

[0081] In some embodiments, there may be two or more soft rubber gates 62.

[0082] The soft rubber gate has a high pulling force, and manual removal is time-consuming. In some embodiments, after injection molding is completed, the pneumatic pressure clamp 11-1 can be rotated to the position of the soft rubber gate 62 by the drive of the rotary drive component. The pneumatic pressure clamp 11-1 clamps the soft rubber gate 62, and the hardware 13 near the workpiece 15 removes the workpiece 15 by adsorption, thereby detaching the soft rubber gate 62 from the workpiece 15.

[0083] This description describes an embodiment that uses a rotary drive component to drive a pneumatic pressure clamp to rotate and grip the soft rubber gate or clamping hardware, thereby achieving automatic gripping of the soft rubber gate. This effectively solves the problems of low efficiency and easy leakage leading to mold damage when manually removing soft rubber gates, avoids production accidents caused by soft rubber gate residue, and improves the stability and automation of the operation.

[0084] In some embodiments, such as Figure 2 As shown, the pneumatic pressure clamp 11-1 also includes a gripper 21, which is equipped with a magnetic induction switch (not shown in the figure).

[0085] The gripper 21 is a clamping structure at the end of the pneumatic pressure clamp 11-1 used to grip the workpiece 15 or the soft rubber gate 62.

[0086] A magnetic induction switch is used to sense the distance between the gripper 21 and the soft rubber gate 62 to control the gripper 21 to clamp or release. In some embodiments, the magnetic induction switch is communicatively connected to the processor, and the magnetic induction switch can cooperate with the processor to control the gripping of the soft rubber gate. For example, after injection molding, when it is necessary to grip the soft rubber gate 62 or disassemble the fitting 13, after the gripper 21 grips the soft rubber gate 62, it transmits a confirmation signal to the processor through the magnetic induction switch. After the processor confirms that each gripper 21 has gripped the soft rubber gate 62, it controls the vacuum supply device to make the suction cup 43 of the fitting located on one side of the workpiece 15 adsorb the workpiece 15 to remove the workpiece 15. The removed workpiece 15 can be transported to the subsequent process by technicians or robotic arms. At this time, the fitting 13 is in an idle state, and technicians or robotic arms can disassemble the fitting 13.

[0087] In some embodiments of this specification, by equipping the pneumatic pressure clamp with grippers that include magnetic induction switches, the grippers can be precisely controlled to pick up the soft plastic gate, preventing damage to the mold caused by the soft plastic gate not being removed.

[0088] In some embodiments, the gripper 21 is also provided with a stress sensor (not shown in the figure).

[0089] A stress sensor is used to acquire the clamping force of the pneumatic pressure clamp 11-1. In some embodiments, the stress sensor is configured to detect the clamping force of the pneumatic pressure clamp 11-1. The clamping force is the force data acquired by the stress sensor as applied by the gripper 21 to the object being clamped. In some embodiments, the stress sensor may be communicatively connected to a processor.

[0090] In some embodiments, if the force data detected by the stress sensor reaches a preset value, the processor can determine that the pneumatic pressure clamp 11-1 is in place. The preset value can be preset by a technician according to different fittings or soft rubber gates. In some embodiments, the preset value can be a range value; if the force data detected by the stress sensor is within the range value, it is considered that the clamp is in place. For the fitting 13, being in place means that the clamped fitting 13 is engaged in the groove of the fixture plate 12 in the longitudinal direction and reaches the position that needs to be fixed. When the processor determines that all fittings 13 are in place, subsequent processing will begin. For the soft rubber gate 62, being in place means that the soft rubber gate 62 can be stably clamped without damaging it. When the processor determines that the soft rubber gate 62 is in place, it controls the gripper 21 of the pneumatic pressure clamp 11-1 to stop applying clamping force.

[0091] Existing technology typically uses ordinary grippers to grasp soft plastic gates. When the grippers close to a certain angle, it is considered that the grip is tight. At this point, the gripping force may be too large, causing damage to the soft plastic gate. In some embodiments of this specification, by incorporating grippers with stress sensors into the pneumatic pressure clamp, the process of gripping and fixing the hardware can be further automated, and damage to the soft plastic gate caused by excessive gripping force can be avoided when holding the soft plastic gate.
