[0042] like Figures 1 to 4As shown, in some embodiments, a positioning fixture 10 includes a support plate 100, a guide assembly 200, a support platform 300 and an elastic member 400. One end of the guide assembly 200 is connected to the support plate 100. The support platform 300 is arranged opposite to the support plate 100, and the support platform 300 is provided with a guide hole 310, and the other end of the guide assembly 200 is slidably penetrated in the guide hole 310. The elastic member 400 is sleeved on the outer periphery of the guide assembly 200, and one end of the elastic member 400 is connected to the support plate 100, and the other end is connected to the support platform 300, and the elastic member 400 is used to provide an elastic force to the support platform 300 away from the support plate 100.

[0043] When the workpiece is placed on the carrier 300, the carrier 300 can slide downward relative to the guide assembly 200, and the carrier 300 squeezes the elastic member 400, so that the elastic member 400 is in a compressed state, and the elastic member 400 provides an upward elastic force on the carrier 300. That is, the carrier 300 can float relatively, and the elastic member 400 has a buffering effect on the carrier 300, reducing the impact force of the carrier 300 on the workpiece, thereby reducing the damage of the carrier 300 to the workpiece and improving the quality of the product.

[0044] It should be noted that the support plate 100 has sufficient strength and rigidity to support the carrier 300 and the workpiece. When the workpiece is placed on the carrier 300, the weight of the workpiece and the external force generated during positioning and processing will be transmitted to the support plate 100 through the guide assembly 200 and the elastic member 400. The support plate 100 has a large contact bottom surface, which can evenly disperse the concentrated force to the placement plane (such as a machine tool table, a workbench, etc.), avoiding displacement or damage caused by excessive local pressure, and ensuring the smooth operation of the positioning fixture 10.

[0045] Specifically, one end of the elastic member 400 is connected to the support plate 100. The support plate 100 bears the pressure from the elastic member 400. When the support platform 300 is pressed close to the support plate 100 by an external force, the elastic member 400 is in a compressed state, and the reaction force of the elastic member 400 is applied to the support plate 100. When the external force disappears, the elastic member 400 will rebound, and the elastic member 400 will push the support platform 300 to reset under the reaction force provided by the support plate 100.

[0046] Specifically, the support plate 100 may be a square plate.

[0047] In some embodiments, the guide assembly 200 is a long strip structure, such as a cylindrical guide rod or a prismatic guide rail. The surface of the guide assembly 200 is smooth to reduce the friction between the guide assembly 200 and the inner wall of the guide hole 310, so as to facilitate the floating of the support platform 300.

[0048] The guide assembly 200 can guide the carrier 300 to move along a predetermined linear direction. That is, the carrier 300 moves in a vertical direction. When the carrier 300 is subjected to an external force, the guide assembly 200 cooperates with the guide hole 310 to limit the carrier 300 from sliding in a direction perpendicular to the support plate 100. For example, in an automated assembly process, when it is necessary to accurately position a workpiece to a certain position, the carrier 300 can accurately move up and down under the guidance of the guide assembly 200 to ensure the assembly accuracy of the workpiece.

[0049] In some embodiments, the carrier platform 300 is arranged parallel to the support plate 100. The carrier platform 300 is a square plate-shaped structure. Positioning protrusions or grooves can be provided on the edge of the carrier platform 300, and the protrusions or grooves are used to accurately place and position the circular workpiece.

[0050] The support platform 300 is provided with a guide hole 310. The guide hole 310 may be circular. The inner diameter of the guide hole 310 is matched with the outer diameter of the guide assembly 200. The gap between the outer wall of the guide assembly 200 and the inner wall of the guide hole 310 needs to be strictly controlled. If the gap is too small, the movement may be stuck, and if the gap is too large, the positioning accuracy will be affected, causing the support platform 300 to shake during the movement.

[0051] The support platform 300 needs to bear the weight of the workpiece. The support platform 300 has sufficient strength and rigidity. When the workpiece is heavy or the positioning fixture 10 needs to bear dynamic loads (such as working in a vibrating environment), the structural design of the support platform 300 needs to take these factors into consideration to prevent deformation or damage.

[0052] In addition to the gravity of the workpiece, the carrier 300 is also subject to other external forces. For example, during the processing, there may be cutting force, clamping force or impact force acting on the workpiece, and these external forces will be transmitted to the carrier 300 through the workpiece. The carrier 300 needs to be able to effectively disperse and withstand these external forces to ensure its own stability and the safety of the workpiece.

[0053] In some embodiments, the elastic member 400 may be a spring. The elastic member 400 is cylindrical and surrounds the outer circumference of the guide assembly 200. Such an arrangement enables the elastic member 400 to fully utilize the axial space of the guide assembly 200, and during the movement of the bearing platform 300, ensures that the elastic force is evenly distributed around the guide assembly 200, so that the bearing platform 300 is subjected to a more balanced force.

[0054] The elastic member 400 is coaxially arranged with the guide assembly 200. The elastic member 400 is sleeved on the outer periphery of the guide assembly 200. The guide assembly 200 provides positioning and guiding functions for the elastic member 400. During the expansion and contraction process of the elastic member 400, the guide assembly 200 ensures that the elastic member 400 expands and contracts along the axial direction to prevent it from bending or twisting. Such an arrangement ensures that the elastic force of the elastic member 400 can be effectively transmitted to the support platform 300 and the support plate 100, while also protecting the elastic member 400 itself and improving the reliability of the operation of the elastic member 400.

[0055] The material of the elastic member 400 has a high elastic modulus and good fatigue performance. For example, the material of the elastic member 400 can be spring steel. Spring steel contains an appropriate amount of alloy elements, such as silicon, manganese, chromium, etc. This element can improve the strength, toughness and elastic limit of the elastic member 400. The high elastic modulus ensures that the elastic member 400 can produce sufficient elastic deformation when subjected to a certain external force, and can return to its original shape after deformation. Good fatigue performance enables the elastic member 400 to withstand long-term repeated expansion and contraction without breaking easily, so as to be suitable for positioning fixtures with frequent movements.

[0056] Specifically, one end of the elastic member 400 is connected to the support platform 300. The elastic force of the elastic member 400 directly acts on the support platform 300. The range of motion and the motion characteristics of the support platform 300 are limited and affected by the elastic member 400. For example, the initial length and elastic coefficient of the elastic member 400 determine how much external force the support platform 300 will start to move, and the maximum displacement of the movement. At the same time, the weight and movement speed of the support platform 300 will also affect the force of the elastic member 400.

[0057] In some embodiments, the guide assembly 200 and the elastic member 400 are provided in plurality, and the plurality of guide assemblies 200 and the plurality of elastic members 400 are provided in one-to-one correspondence.

[0058] It should be noted that the plurality of elastic members 400 are evenly distributed between the carrier platform 300 and the support plate 100. This distribution can balance the elastic force on the carrier platform 300. For example, the guide assembly 200 and the corresponding elastic member 400 are respectively arranged at the four corners of the square carrier platform 300, so that the carrier platform 300 can be evenly elastically supported in all directions, thereby preventing the carrier platform 300 from tilting or moving unsmoothly due to excessive force on a single point.

[0059] Each elastic member 400 still surrounds the outer periphery of the corresponding guide assembly 200, and its structural form may be different according to specific design requirements and space limitations. The size, shape and elastic parameters of each elastic member 400 should be consistent to ensure that each elastic member 400 can work together during operation to provide a uniform and stable elastic force.

[0060] During the resetting process of the elastic member 400, the combined force of the multiple elastic members 400 can more effectively push the support platform 300 back to the initial position. Compared with a single elastic member 400, the multiple elastic members 400 can provide a greater resetting force, and because of the uniform distribution, the support platform 300 can return to the original position more smoothly and accurately during the resetting process, reducing the position deviation caused by uneven elastic force.

[0061] Through multiple guide assemblies 200 and corresponding elastic members 400, the carrier platform 300 has more stable guidance and support during the up and down movement. The elastic member 400 can be adjusted in real time according to the position and force of the carrier platform 300, providing a balanced elastic force, and effectively reducing the shaking and deviation of the carrier platform 300. Multiple elastic members 400 can jointly absorb and disperse external impact forces to provide better buffering and shock absorption effects. When the workpiece has a large impact force during the placement process or vibrates during the processing process, the elastic member 400 can effectively reduce the impact of these forces on the carrier platform 300 and the workpiece. This not only protects the workpiece from damage, but also reduces the vibration of the positioning fixture 10 itself, extending the service life of the positioning fixture 10.

[0062] In some embodiments, the positioning fixture 10 includes a connecting rod 510 and a stop block 520. One end of the connecting rod 510 is connected to the support plate 100, and the other end of the connecting rod 510 is connected to the stop block 520. The stop block 520 is arranged opposite to the support plate 100, and the stop block 520 can limit the bearing platform 300 from sliding in a direction away from the support plate 100. Specifically, the structures of the connecting rod 510 and the stop block 520 can be screws.

[0063] When the elastic member 400 resets the supporting platform 300, the elastic member 400 provides a force to the limit block 520 in the direction away from the support plate 100. The supporting platform 300 slides away from the support plate 100. That is, the supporting platform 300 slides upward in the vertical direction. When the resetting is completed, the supporting platform 300 will hit the limit member and stop sliding upward in the vertical direction. The limit block 520 accurately controls the maximum displacement of the supporting platform 300, ensures that the supporting platform 300 moves within a specified range, prevents the supporting platform 300 from excessive displacement when the elastic member 400 fails or is subjected to abnormal external force, and avoids the supporting platform 300 from colliding with other equipment or personnel.

[0064] Specifically, a plurality of connecting rods 510 and limiting blocks 520 may be provided. More specifically, two connecting rods 510 and limiting blocks 520 may be provided. One connecting rod 510 and limiting block 520 are provided on one side of the carrying platform 300, and another connecting rod 510 and limiting block 520 are provided on the other side of the carrying platform 300, so as to form a symmetrical layout. This layout enables the carrying platform 300 to be effectively limited and supported on both sides, and avoids the situation in which the carrying platform 300 is tilted to one side due to uneven force during movement caused by the unilateral setting.

[0065] In some embodiments, the positioning fixture 10 also includes a first driving member 610, a connecting member 620 and a stripping assembly 630, one end of the connecting member 620 is connected to the first driving member 610, and the other end is connected to the stripping assembly 630, and the connecting member 620 is passed through the supporting platform 300, and the stripping assembly 630 is placed on the supporting platform 300, and the first driving member 610 is used to move the stripping assembly 630 away from the supporting platform 300.

[0066] It should be noted that the first driving member 610 is used as a power source. The first driving member 610 can provide power to move the stripping assembly 630. The first driving member 610 can be a cylinder, a hydraulic cylinder or an electric push rod.

[0067] The connecting member 620 may be a slender rod-shaped structure to adapt to movement in the through hole of the carrier 300. One end of the connecting member 620 is firmly connected to the output end of the first driving member 610 to ensure that the power can be effectively transmitted, and the other end is connected to the stripping assembly 630. The connection method needs to ensure that it will not loosen or fall off during the movement, for example, a threaded connection or a pin connection can be used.

[0068] The stripping assembly 630 is placed on the support platform 300. The shape and structure of the stripping assembly 630 depend on the shape of the workpiece and the stripping method. The stripping assembly 630 can be a flat structure, and the stripping is achieved by lifting the workpiece upward. The stripping assembly 630 can also be a fixture with a special shape, which pushes the workpiece from the side to detach from the support platform 300. The material of the stripping assembly 630 needs to have a certain strength and wear resistance to ensure that it will not be damaged during long-term use.

[0069] After the workpiece processing or assembly is completed, the stripping assembly 630 is driven away from the carrier 300 by the first driving member 610, and the workpiece can be smoothly removed from the carrier 300. This automated stripping method is more efficient and accurate than manual stripping. For example, on an automated production line, when a batch of workpieces is processed, all workpieces can be quickly removed from the carrier 300 by starting the first driving member 610, thereby improving production efficiency and reducing the time and labor intensity of manual operation.

[0070] In some embodiments, an assembly device includes a carrying mechanism 20, a second driving member 30 and a positioning fixture 10. The second driving member 30 is connected to the carrying mechanism 20, and the positioning fixture 10 is disposed on the carrying mechanism 20. The second driving member 30 is used to drive the carrying mechanism 20 to rotate. Specifically, the carrying mechanism 20 can be a disc structure.

[0071] It should be noted that the bearing mechanism 20 has a bearing function for the positioning fixture 10. The structure of the bearing mechanism 20 needs to have sufficient strength and stability to ensure that the bearing mechanism 20 can stably support the positioning fixture 10 and the workpiece during the rotation process. The connection between the bearing mechanism 20 and the positioning fixture 10 can be bolt connection, slot matching, etc., to ensure that the positioning fixture 10 will not loosen or move on the bearing mechanism 20.

[0072] The second driving member 30 is connected to the supporting mechanism 20. The second driving member 30 is a power source for driving the supporting mechanism 20 to rotate. The second driving member 30 can be a rotating power device such as an electric motor or a hydraulic motor.

[0073] When the second driving member 30 is started, the rotational power generated by the second driving member 30 is transmitted to the supporting mechanism 20 through the connecting member, so that the supporting mechanism 20 starts to rotate. The rotation of the supporting mechanism 20 drives the positioning fixture 10 to rotate synchronously, and the workpiece on the positioning fixture 10 also rotates synchronously. The accuracy and stability of the rotational motion depends on the control accuracy of the second driving member 30 and the structural design of the supporting mechanism 20 and the positioning fixture 10.

[0074] In some embodiments, a plurality of positioning jigs 10 are provided. The plurality of positioning jigs 10 are arranged at equal intervals on the carrying mechanism 20. Specifically, there may be eight positioning jigs 10. Specifically, the plurality of positioning jigs 10 are arranged at equal intervals on the outer edge of the disc.

[0075] A plurality of positioning jigs 10 are arranged on the carrier mechanism 20 to increase the working capacity of the assembly device. The plurality of positioning jigs 10 can simultaneously position a plurality of workpieces, thereby improving the working efficiency of the assembly device. For example, in a batch production scenario, a plurality of workpieces can be processed at one time, reducing the processing time of a single workpiece, thereby improving the overall production speed.

[0076] The positioning jigs 10 are evenly spaced on the supporting mechanism 20. This distribution makes the supporting mechanism 20 more balanced in force during rotation, and the evenly spaced distribution helps reduce vibration and instability caused by the center of gravity offset. At the same time, the evenly spaced setting also facilitates automated control, so that each positioning jig 10 can reach each work station in turn according to a fixed rotation angle, which is convenient for accurately arranging the assembly process.

[0077] In some embodiments, the first driving member 610 includes a motor and a divider, the driving shaft of the motor is connected to the output shaft of the divider, and the divider is connected to the supporting mechanism 20, and the motor drives the divider to rotate so that the divider drives the supporting mechanism 20 to rotate.

[0078] It should be noted that the motor is the source of power. The motor outputs continuous rotational power through the drive shaft. The motor can be a servo motor, a stepper motor or a common AC motor. The divider outputs according to the set angle and time interval. The connection method between the divider and the supporting mechanism 20 can be a flange connection, a key connection, etc., which effectively transmits the output power of the divider to the supporting mechanism 20.

[0079] After the motor is started, the drive shaft of the motor rotates and transmits power to the divider. The divider can convert the continuous rotational motion of the motor into intermittent motion, and the output shaft of the divider rotates at a certain angle interval and time period. The intermittent rotation of the support mechanism 20 drives multiple positioning jigs 10 to rotate synchronously. Since the positioning jigs 10 are arranged at equal intervals on the support mechanism 20, during each intermittent rotation of the support mechanism 20, the positioning jigs 10 can accurately deliver the workpieces to each assembly station in turn. This collaborative working mode ensures that each workpiece has enough time to perform assembly operations at different stations, while also ensuring the orderliness and accuracy of the entire assembly process.

[0080] In some embodiments, the assembly device further includes a position sensor 40. The position sensor 40 is disposed on the carrying mechanism 20. The position sensor 40 is used to sense the position of the positioning fixture 10 on the carrying mechanism 20.

[0081] Specifically, the sensing area of ​​the position sensor 40 faces the positioning fixture 10 so as to obtain the position information of the positioning fixture 10 in real time. After the position sensor 40 senses the position of the positioning fixture 10, it converts the position information into an electrical signal output. This electrical signal can be an analog signal or a digital signal, depending on the type of sensor. These signals will be transmitted to the control system, which processes and analyzes the signals, for example, to determine whether the positioning fixture 10 has reached the designated assembly station, whether the rotation angle is accurate, etc. The use of the position sensor 40 enables the assembly device to achieve automated position control. On an automated production line, there is no need for manual frequent checks on the position of the positioning fixture 10, and the operating status is automatically adjusted according to the feedback information from the sensor. This not only improves production efficiency, but also reduces the errors and uncertainties caused by manual operation, making the entire assembly process more stable and efficient.

[0082] In this assembly device, the position sensor 40 is arranged on the carrier mechanism 20, and the installation position of the position sensor 40 needs to be determined according to the shape, size and assembly process requirements of the positioning fixture 10. The sensor can accurately sense the position change of the positioning fixture 10, and the installation method must ensure its stability to avoid loosening or displacement during the rotation of the carrier mechanism 20.

[0083] Specifically, the position sensor 40 may be a photoelectric position sensor 40 , an inductive position sensor 40 , a capacitive position sensor 40 , or the like.

[0084] The photoelectric position sensor 40 can determine the position of the positioning fixture 10 by emitting a light beam and detecting reflected light or occlusion. For example, a reflective mark is set on the positioning fixture 10. When the supporting mechanism 20 rotates, the light emitted by the sensor is irradiated onto the reflective mark, and the reflected light is received by the sensor. The position of the positioning fixture 10 is determined by detecting parameters such as the intensity and time of the reflected light.

[0085] For the inductive position sensor 40 , when the positioning fixture 10 (especially the positioning fixture 10 made of metal) approaches or moves away from the sensor, the inductance value of the sensor coil will change. The inductive position sensor 40 determines the position of the positioning fixture 10 by detecting the change in inductance.

[0086] The capacitive position sensor 40 works based on the change of capacitance. When the positioning fixture 10 is close to the electrodes of the sensor, the capacitance between the electrodes will change, and the capacitive position sensor 40 senses the position of the positioning fixture 10 according to the change in capacitance.

[0087] In some embodiments, the assembly device further includes a detection sensor 50 , which is disposed on the carrying mechanism 20 , and is used to detect the workpiece on the carrying platform 300 .

[0088] It should be noted that after the detection sensor 50 detects the relevant information of the workpiece, it will convert it into an electrical signal output. These signals can be digital signals or analog signals, and then transmitted to the control system. The control system processes and analyzes the signals, for example, to determine whether the workpiece is placed correctly, whether there are defects, whether the size meets the requirements, etc.

[0089] The detection sensor 50 can monitor the status of the workpiece on the carrier 300 in real time, including whether the workpiece exists, whether the position is correct, whether the appearance is defective, etc. For example, in the process of assembling electronic components, it can be detected whether the chip is correctly placed on the carrier 300 to avoid empty or misplaced positions, thereby improving the yield rate of the product. For workpieces with appearance quality requirements, such as surface scratches and deformations of battery core components, visual sensors can perform effective detection, timely detect workpieces with quality problems, and prevent them from entering the next assembly process.

[0090] Specifically, the detection sensor 50 may be a photoelectric sensor, a proximity sensor, a visual sensor, or the like.

[0091] The emitter and receiver of the photoelectric sensor are located on both sides of the carrier 300. When the workpiece is placed on the carrier 300, it blocks the light, so that the receiver cannot receive the light signal, thereby detecting the existence of the workpiece. The reflective photoelectric sensor has the emitter and receiver on the same side, and determines whether the workpiece exists by detecting the light reflected from the workpiece.

[0092] For proximity sensors (inductive and capacitive), inductive proximity sensors are mainly used to detect metal workpieces. When a metal workpiece approaches the sensor, it changes the inductance of the sensor coil, and the presence of the workpiece is determined by detecting this inductance change. Capacitive proximity sensors can detect both metal and non-metal workpieces. Capacitive proximity sensors detect based on the change in capacitance between electrodes when the workpiece approaches the sensor.

[0093] The visual sensor uses image recognition technology to analyze the shape, size, position and other information of the workpiece by capturing the image of the workpiece on the carrier 300. The visual sensor can perform comprehensive inspection of the workpiece, including appearance defects, dimensional accuracy and other aspects.

Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
