Description

Technical Field

[0001] This invention relates to the field of automation technology, and in particular to an automatic gasket placement device and its placement method. Background Technology

[0002] In the assembly and production of precision electronics, automotive parts, or optical instruments, gaskets of a specific thickness are usually installed between two mating workpieces to ensure assembly accuracy, sealing, or predetermined gaps. Traditional gasket installation methods rely heavily on manual measurement, selection, and placement. This involves first measuring the actual height or gap of the workpieces using tools such as a micrometer, manually calculating the required gasket thickness, and then selecting gaskets of the appropriate specifications from the material box for placement.

[0003] However, with the increasing demands for product consistency and assembly precision in industrial production, the drawbacks of traditional manual operation methods have become increasingly apparent. Firstly, manual measurement and calculation are inefficient and prone to human error, leading to inconsistent batch quality. Secondly, manually selecting gasket thickness by visual inspection is difficult to guarantee absolute accuracy, easily resulting in incorrect selection and assembly that is too tight or too loose. Finally, manual placement suffers from poor consistency, failing to meet the stringent requirements of modern high-precision products for placement pressure and positional accuracy. Therefore, there is an urgent need for automated equipment capable of automatic measurement, intelligent material selection, and precise placement to solve these technical problems. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide an automatic gasket mounting device and its mounting method, which can effectively solve the technical problem that traditional gasket mounting devices cannot achieve automatic matching and selection of gaskets for multiple workpiece gaps and assembly.

[0005] To address the aforementioned technical problems, this invention provides an automatic gasket mounting device, comprising: a first clamping assembly including a first pressing assembly and two spring-loaded pins, wherein the first pressing assembly drives the two spring-loaded pins to clamp a first workpiece and avoid its measuring position; a second clamping assembly including a second pressing assembly and a pusher, wherein the second pressing assembly drives the pusher to clamp a second workpiece and avoid its measuring position; and a laser measurement module including at least two laser displacement sensors configured to perform non-contact height measurement of their measuring positions after the first and second workpieces are fixed. The system acquires gap data between the two components; a feeding mechanism includes several feeding feeders, each feeding feeder corresponding to a gasket of a certain specification; a picking mechanism includes a clamping component for picking up the corresponding gasket from the feeding mechanism; a mounting mechanism includes a suction nozzle with several suction holes for picking up the gasket from the clamping component and mounting the gasket; and a control unit, communicatively connected to the laser measurement module and the picking mechanism, for receiving the gap data and, based on a preset target gap value and a gasket specification library, calculating and controlling the picking mechanism in real time to pick up the required specification of gasket.

[0006] In one feasible implementation, it includes a first direction, a second direction, and a third direction that are perpendicular to each other. The first clamping assembly also includes a first base plate, and a carrier carrying the first workpiece is fixed to the first base plate. The first pressing assembly includes a flip-top plate, a flip-top base, a sliding assembly, a slider cover plate, and a first pressing drive. The flip-top plate has a first end and a second end opposite to each other along the first direction. The first end is connected to the spring pin, and the second end is hinged to the flip-top base. The flip-top base is fixedly connected to the sliding assembly. The sliding assembly is disposed on the base plate and, driven by the first pressing drive, drives the spring pin to press the first workpiece. The slider cover plate is fixedly connected to the first base plate and covers the sliding assembly.

[0007] In one feasible implementation, the sliding assembly includes a first wedge-shaped slider and a second wedge-shaped slider with wedge surfaces tangent to each other. The first pressing drive is disposed on one side of the first wedge-shaped slider along the second direction. When the first pressing drive presses against the first wedge-shaped slider along the second direction, the first wedge-shaped slider pushes the second wedge-shaped slider to move along the first direction. The flip-top base is fixedly connected to the second wedge-shaped slider.

[0008] In one feasible implementation, the first clamping assembly further includes a reset drive, which is used to drive the first wedge slider and the second wedge slider to reset, thereby releasing the clamping of the first workpiece.

[0009] In one feasible implementation, the first clamping drive includes a pin, a connecting rod, and a handle. The pin is disposed on the first base plate. One end of the connecting rod is sleeved on the pin, and the other end is provided with the handle. The end of the connecting rod that is rotatably connected to the pin is provided with a cam structure. Rotating the connecting rod can drive the cam to apply a driving force in the second direction to the first wedge-shaped slider.

[0010] In one feasible implementation, the material handling mechanism is further configured with a material handling transfer drive device, which is capable of driving the gripping assembly to move along the first direction, the second direction, or a third direction.

[0011] In one feasible implementation, the mounting mechanism further includes a rotary drive configured to drive the nozzle to rotate about the third direction to align and attach the pad on the nozzle.

[0012] In one feasible implementation, the mounting mechanism is further configured with a mounting transfer drive device, which is configured to drive the nozzle to move along the first direction, the second direction, or a third direction, wherein the suction direction of the nozzle is consistent with the third direction.

[0013] In one feasible implementation, the laser measurement module includes at least two high-precision laser displacement sensors configured to perform non-contact height measurement at a designated position after the product is fixed, thereby obtaining the actual height difference data between the products.

[0014] Accordingly, this application also provides a mounting method based on the automatic gasket mounting equipment described in any of the foregoing claims, characterized by comprising the following steps: The first workpiece and the second workpiece are respectively loaded into the first clamping assembly and the second clamping assembly; The height of the first and second workpieces is measured by a dual-station laser height measuring mechanism, and the assembly step difference and target gap between the two are calculated. According to the target gap, the corresponding specification of the gasket is picked up from the feeding mechanism by the gripping component of the material picking mechanism and removed from the feeding mechanism; The nozzle of the mounting mechanism picks up the pad from the clamping assembly and places the pad onto the measuring position of the second workpiece to complete the matching mounting.

[0015] Implementing this invention has the following beneficial effects: The automatic gasket mounting equipment provided by this invention achieves closed-loop control of the entire process from workpiece positioning and gap measurement to intelligent gasket selection and mounting through integrated automation design. Specifically, the equipment utilizes first and second clamping components to accurately position and flexibly clamp the workpiece, and ensures the accessibility of the measurement position through an obstacle avoidance design; the laser measurement module can quickly acquire the actual gap data between workpieces and transmit it to the control unit; the control unit, based on a preset algorithm and a gasket specification library, makes real-time decisions and instructs the material picking mechanism to select the gasket with the most matching thickness, and finally, the mounting mechanism equipped with a suction nozzle completes the high-precision mounting. This technical solution completely eliminates the traditional manual measurement, calculation, and gasket selection process, which not only significantly improves production efficiency and product yield, but also ensures the consistency and reliability of batch products through the machine's high repeatability positioning accuracy and real-time feedback from sensors, effectively solving the technical problems of low assembly accuracy and high rework rate caused by human error in the prior art.

[0024] Please refer to Figures 1 to 11 This application provides an automatic gasket mounting device for calculating and mounting materials to fit two workpieces together. The automatic gasket mounting device includes a first clamping assembly 1 for clamping a first workpiece, a second clamping assembly 2 for clamping a second workpiece, a laser measurement module 3, a feeding mechanism 4, a picking mechanism 5, a mounting mechanism 6, and a control unit. The first clamping assembly 1 includes a first pressing assembly 11 and two spring-loaded pins 12. The first pressing assembly 11 drives the two spring-loaded pins 12 to press the first workpiece and avoid its measuring position. The second clamping assembly 2 includes a second pressing assembly 21 and a pusher 22. The second pressing assembly 21 drives the pusher 22 to press the second workpiece and avoid its measuring position. The laser measurement module 3 includes at least two laser displacement sensors 31. The laser measurement module 3 is configured to perform non-contact height measurement of the measuring position of the first and second workpieces after they are fixed, and to obtain the gap data between them. The feeding mechanism 4 includes a plurality of feeding feeders 41. Each feeding feeder 41 corresponds to a gasket of a certain specification. The picking mechanism 5 includes a clamping assembly 51. The clamping assembly 51 is used to clamp the corresponding gasket from the feeding mechanism 4. The mounting mechanism 6 includes a suction nozzle 61, and the suction nozzle 61 has a plurality of annular suction holes 611 for picking up the gasket from the clamping assembly 51 and mounting the gasket. The control unit communicates with the laser measurement module 3 and the material handling mechanism 5 to receive the gap data and, based on the preset target gap value and the gasket specification library, calculates and controls the material handling mechanism 5 to pick up the required gasket specifications in real time.

[0025] The automatic gasket placement equipment provided by this invention utilizes first and second clamping components 2 to precisely position and flexibly clamp the workpiece, facilitating measurement by the laser measurement module 3. The laser measurement module 3 can quickly acquire actual gap data between workpieces and transmit it to the control unit. Based on a preset algorithm and a gasket specification library, the control unit makes real-time decisions and instructs the material handling mechanism 5 to select the most suitable gasket specification. Finally, the placement mechanism 6, equipped with a suction nozzle 61, completes the high-precision placement. This technical solution achieves automatic selection and placement, significantly improving production efficiency and product yield. Furthermore, through the machine's high repeatability and real-time sensor feedback, it ensures the consistency and reliability of batch products. Through integrated automation design, a closed-loop control system is achieved for the entire process, from workpiece positioning and gap measurement to intelligent gasket selection and placement.

[0026] To facilitate the description of the technical solution, the three mutually perpendicular directions of the curved flexible flat cable mounting device are defined as the first direction X, the second direction Y, and the third direction Z. The third direction Z is the vertical direction.

[0027] In one feasible embodiment, the first clamping assembly 1 further includes a first base plate 13, and a first carrier carrying the first workpiece is fixed to the first base plate 13. The first pressing assembly 11 includes a flip cover plate 111, a flip cover base 112, a sliding assembly 113, a slider cover plate 114, and a first pressing drive member 115. The flip cover plate 111 has a first end and a second end opposite to each other along a first direction X. The first end of the flip cover plate 111 is connected to the spring pin 12, and the second end is hinged to the flip cover base 112. The flip cover base 112 is fixedly connected to the sliding assembly 113. The sliding assembly 113 is disposed on the base plate and, driven by the first pressing drive member 115, drives the spring pin 12 to press the first workpiece. The slider cover plate 114 is fixedly connected to the first base plate 13 and covers the sliding assembly 113. Further, a flip cover limiting block 116 is also provided above the slider cover plate 114. The flip-cover limiting block 116 is used to limit the position of the flip-cover plate 111. Specifically, the flip-cover limiting block 116 is arranged vertically and located in the middle of the flip-cover plate 111. When the first clamping assembly 1 clamps the first workpiece, the flip-cover limiting block 116 supports the flip-cover plate 111 along the vertical direction. Of course, the flip-cover limiting block 116 also restricts the flip-cover plate 111 from excessive rotation. Furthermore, the flip-cover limiting block 116 has a groove structure, which can both support and limit the position of the flip-cover plate 111 and also serve as a guide.

[0028] In one feasible embodiment, the sliding assembly 113 includes a first wedge-shaped slider 131 and a second wedge-shaped slider 1132 with tangent wedge surfaces. A first pressing drive member 115 is disposed on one side of the first wedge-shaped slider 131 along the second direction Y. When the first pressing drive member 115 presses against the first wedge-shaped slider 131 along the second direction Y, the first wedge-shaped slider 131 pushes the second wedge-shaped slider 1132 to move along the first direction X, and the flip-top base 112 is fixedly connected to the second wedge-shaped slider 1132.

[0029] In one feasible embodiment, the first clamping assembly 11 further includes a reset drive 117. The reset drive 117 is used to drive the first wedge slider 131 and the second wedge slider 1132 to reset, thereby releasing the clamping of the first workpiece.

[0030] Furthermore, the reset drive 117 includes two reset springs, which are respectively arranged along the first direction X and the second direction Y.

[0031] In one feasible embodiment, the first clamping drive 115 includes a pin, a connecting rod, and a handle. The pin is disposed on the first base plate 13. One end of the connecting rod is sleeved on the pin, and the other end is provided with the handle. The end of the connecting rod rotatably connected to the pin is provided with a cam structure, and rotating the connecting rod can drive the cam to apply a driving force along the second direction Y to the first wedge-shaped slider 131.

[0032] In one feasible implementation, the spring-loaded pin 12 is connected to the flip-top plate 111 via a pin mounting base 118. The pin mounting base 118 has a U-shaped structure, with each of its two arms connected to a spring-loaded pin 12. The connection points between the two arms and the flip-top plate 111 are connected by fasteners or integrally formed. Through holes are provided at the connection points between the two arms and the spring-loaded pins 12. The fixed end of the spring-loaded pin 12 passes through the through holes, while the movable end presses against the first workpiece to achieve flexible pressure on the first workpiece and avoid damage. Furthermore, the two arms of the pin mounting base 118 are asymmetrically arranged and also have clearance to facilitate laser measurement.

[0033] In one feasible implementation, the first pressing drive 115 may also be other structures that can apply a driving force along the second direction Y to the first wedge slider 131, such as a linear pressing structure that directly pushes along the second direction Y.

[0034] In one feasible embodiment, the second clamping assembly 21 of the second clamping assembly 2 includes a second clamping drive member. The second clamping drive member is a cylinder. Please refer to... Figure 6 The pusher head 22 is a contouring structure corresponding to the second workpiece. The pusher head 22 is Y-shaped, and combined with the contouring structure of the second carrier that carries the second workpiece, the pusher head 22 can achieve the positioning of the second workpiece with a single component.

[0035] In one feasible embodiment, the first clamping assembly 1 and the second clamping assembly 2 are disposed on the mounting and transfer platform 10. The fixed end of the mounting and transfer platform 10 is fixed to the substrate 7, and the first clamping assembly 1 and the second clamping assembly 2 are disposed at its movable end. The mounting and transfer platform 10 is disposed along the second direction Y to facilitate clamping workpieces or measuring and mounting workpieces.

[0036] In one feasible embodiment, the material handling mechanism 5 is further configured with a material handling transfer drive device 52. The material handling transfer drive device 52 is capable of driving the gripping assembly 51 to move along the first direction X, the second direction Y, or the third direction Z. The material handling transfer drive device 52 may include a linear module parallel to the first direction X and a lifting drive assembly disposed on the linear module.

[0037] In one feasible implementation, please refer to Figure 8 The clamping component 51 adopts a double-sided clamping structure and uses micro-torque clamping to clamp only the edge of the gasket wall thickness. The clamping force is adjustable to prevent deformation of the annular metal gasket.

[0038] In one feasible implementation, the mounting mechanism 6 further includes a rotation drive 62 configured to drive the nozzle 61 to rotate about the third direction Z to align and attach the pad on the nozzle 61.

[0039] Furthermore, the mounting mechanism 6 also includes a fixing plate, and the suction nozzle 61 is connected to the output end of the rotary drive device 62 through the fixing plate. For example, in this embodiment, two gaskets need to be mounted, and two sets of suction nozzles 61 and their related components are fixed on the fixing plate.

[0040] The mounting mechanism 6 further includes an angle adjustment block 621, a guide rail fixing block 622, a pressure sensor 624 fixing block 623, a pressure sensor 624, a floating structure 625, and a pressure adjustment module 626. The angle adjustment block 621 is fixedly connected to the suction nozzle 61. The guide rail fixing block 622 has a slot, and the angle adjustment block 621 has a strip-shaped protrusion that slides within the slot of the guide rail fixing block 622. By adjusting the position of the strip-shaped protrusion and the slot, the suction nozzle 61 can be aligned and adsorbed, ensuring that the suction nozzle 61 is parallel and adhered to the workpiece surface. The pressure sensor 624 fixing block 623 is fixed to the guide rail fixing block 622. One end of the pressure sensor 624 is fixed to the sensor fixing block in the vertical direction, and the other end is provided with a floating structure 625. The floating structure 625 is connected to the fixed end of the pressure adjustment module 626, and the movable end of the pressure adjustment module 626 is fixedly connected to the guide rail fixing block 622. The guide rail fixing block 622 and the fixed end of the pressure adjustment module 626 are also connected by a tension spring. This structural arrangement allows for precise control of the suction and attachment of the nozzle 61 in the vertical direction, preventing damage to the workpiece due to excessive pressure or affecting the attachment effect due to insufficient pressure. Furthermore, the pressure adjustment module 626 includes a cylinder fixing plate, a linear guide rail, and a slider. The linear guide rail is fixed to the cylinder fixing plate, the slider is slidably connected to the linear guide rail, and the guide rail fixing block 622 is fixedly connected to the slider. A sliding cylinder is also provided on the other side of the cylinder fixing plate to precisely control the suction and attachment of the nozzle 61 in the vertical direction, preventing damage to the workpiece due to excessive pressure or affecting the attachment effect due to insufficient pressure.

[0041] In one feasible implementation, the mounting mechanism 6 is further equipped with a visual positioning component 63. The visual positioning component 63, together with the rotary drive device 62, is fixed to the fixed plate and connected to the gantry to visually determine the mounting position.

[0042] In one feasible embodiment, the mounting mechanism 6 is further configured with a mounting transfer drive device. The mounting transfer drive device is configured to drive the suction nozzle 61 to move along the first direction X, the second direction Y, or a third direction Z, with the suction direction of the suction nozzle 61 aligned with the third direction Z. Further, the mounting transfer drive device can also be a gantry-type three-axis motion platform, fixedly mounted on the substrate 7 of the automatic pad mounting equipment. The x-axis of the gantry-type three-axis motion platform is aligned with the first direction X, the y-axis with the second direction Y, and the z-axis with the third direction Z. Since the gantry motion platform is a conventional structure, and its specific structure is not the focus of this application, its specific structure and working principle will not be described in detail in this application. In one feasible implementation, the laser measurement module 3 includes at least two high-precision laser displacement sensors 31, configured to perform non-contact height measurement at designated positions after the product is fixed, obtaining actual height difference data between the products. This embodiment exemplarily demonstrates two high-precision laser displacement sensors 31. The two high-precision laser displacement sensors 31 detect the measurement positions of the first workpiece and the second workpiece, respectively. Further, the high-precision laser displacement sensors 31 are configured to measure the step height of the first workpiece and the step height of the second workpiece, calculate the target assembly gap based on the difference, and automatically match a shim of corresponding thickness. With the cooperation of the first clamping assembly 1 and the second clamping assembly 2, the measurement positions of the first and second workpieces can be accurately and stably exposed, facilitating sensor detection.

[0043] Furthermore, the laser measurement module 3 can be mounted on the same gantry motion platform as the mounting mechanism 6. Both the laser measurement module 3 and the mounting mechanism 6 can also each have a corresponding lifting drive module, which is connected to the gantry motion platform to achieve three-axis motion.

[0044] Since the feeder 41 structure is a conventional structure, and its specific structure is not the focus of this application, its specific structure and working principle will not be described in detail in this application.

[0045] Accordingly, this application also provides a mounting method based on the above-mentioned automatic gasket mounting equipment. The mounting method includes the following steps: The first workpiece and the second workpiece are respectively loaded into the first clamping assembly 1 and the second clamping assembly 2; The height of the first and second workpieces is measured by a dual-station laser height measuring mechanism, and the assembly step difference and target gap between the two are calculated. According to the target gap, the corresponding specification of the gasket is picked up from the feeding mechanism 4 by the clamping component 51 of the picking mechanism 5 and removed from the feeding mechanism 4; The nozzle 61 of the mounting mechanism 6 picks up the pad from the clamping assembly 51 and mounts the pad to the measuring position of the second workpiece to complete the matching mounting.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
