Description

Technical Field

[0001] This application relates to the field of workpiece and flexible component assembly technology, specifically to an assembly device and assembly method. Background Technology

[0002] In actual production, workpieces, such as glass panels, need to be assembled into flexible components, and the required structure is formed on the workpiece through injection molding. Currently, rigid assembly is commonly used to assemble workpieces into flexible components. However, rigid assembly can result in damage to both the workpiece and the flexible component; furthermore, since the workpiece and flexible component are usually interference-fitted, friction can easily occur between the workpiece and the side of the flexible component during assembly, hindering rapid assembly and thus affecting assembly efficiency. Summary of the Invention

[0003] In view of the above, it is necessary to propose an assembly equipment and assembly method to make it easier to assemble workpieces into flexible parts, and to prevent workpieces from being damaged during the assembly process, thereby improving assembly efficiency.

[0004] This application provides an assembly device for assembling a workpiece onto a flexible component. The flexible component has a through groove, and the workpiece is assembled within the through groove. The assembly device includes a base, an airflow channel, and a transfer mechanism. The base is used to place the flexible component and to form a receiving space with the flexible component and the workpiece. The airflow channel communicates with the receiving space and is used to supply air to the receiving space to expand the flexible component. The transfer mechanism is disposed relative to the base and is used to move the workpiece toward the flexible component on the base to place the workpiece within the expanded flexible component. The airflow channel is also used to evacuate air from the receiving space to make the flexible component conform to the workpiece.

[0005] When the above-mentioned assembly equipment is in use, the transfer mechanism moves the workpiece toward the flexible part on the base. The base, the flexible part and the workpiece form a receiving space. Before the transfer mechanism moves the workpiece to the flexible part, the airflow channel sends air into the receiving space. The air pressure in the receiving space increases, causing the flexible part to be expanded, so that the workpiece can be inserted into the flexible part for assembly. The transfer mechanism inserts the workpiece into the flexible part based on the expansion of the flexible part. After the transfer mechanism inserts the workpiece into the flexible part, the airflow channel can also evacuate the receiving space to reduce the pressure, thereby making the flexible part fit against the workpiece. In this way, the action of assembling the workpiece into the flexible part is completed.

[0006] The assembly equipment provided in this application, through the cooperation of the base, airflow channel, and transfer mechanism, allows the workpiece to be inserted into the flexible part while it is stretched open, reducing friction between the workpiece and the sides of the flexible part. This facilitates easier assembly of the workpiece into the flexible part, thereby increasing the speed of workpiece assembly and improving assembly efficiency. Furthermore, since the workpiece is inserted into the flexible part while it is stretched open, the probability of damage to the workpiece and flexible part during assembly is reduced, which helps ensure workpiece quality and extend the service life of the flexible part. The airflow channel also evacuates air from the receiving space, allowing the flexible part to fit better against the workpiece, improving the yield rate of workpiece assembly into the flexible part. Additionally, the airflow channel evacuates air from the receiving space, removing excess gas or creating a vacuum environment within the receiving space. During injection molding, this reduces the impact of gas on injection molding yield, improving injection molding quality.

[0007] In some embodiments, the assembly equipment further includes: a pressure sensor disposed on the transfer mechanism for detecting the pressure applied by the transfer mechanism when assembling the workpiece onto the flexible component; and a controller coupled to the pressure sensor and the transfer mechanism for controlling the transfer mechanism to release the workpiece based on the pressure sensed by the pressure sensor reaching a preset pressure range.

[0008] In some embodiments, the controller is further configured to control the airflow channel via a control switch, and the airflow channel is further configured to stop supplying air and start pumping air when the pressure sensed by the pressure sensor reaches a preset pressure range under the control of the control switch.

[0009] In some embodiments, the controller is further configured to control the airflow channel via a control switch, and the airflow channel is further configured to stop supplying air when the transfer mechanism reaches a preset position under the control of the control switch.

[0010] In some embodiments, the transfer mechanism includes: a motion component disposed relative to the base; a gripper connected to the motion component for gripping the workpiece and for moving the workpiece toward the flexible member on the base via the motion component; wherein the pressure sensor is disposed between the gripper and the motion component.

[0011] In some embodiments, the gripper includes: a conductive member connected to the pressure sensor, the conductive member having a stop portion protruding radially; a connecting seat disposed on the side of the pressure sensor away from the motion component, the connecting seat having a receiving cavity, the receiving cavity having a first opening and a second opening at both ends; a portion of the conductive member passing through the first opening and located within the receiving cavity, the stop portion dividing the receiving cavity into a first cavity and a second cavity, the first opening communicating with the first cavity, and the second opening communicating with the second cavity; a base plate connected to the connecting seat and abutting against the second opening, and the side of the base plate away from the conductive member being used to adsorb the workpiece; a first elastic member sleeved on the conductive member and located within the first cavity; and a second elastic member sleeved on the conductive member and located within the second cavity.

[0012] In some embodiments, the gripper further includes at least one distance sensor, all connected to the motion component, for detecting the adsorbed workpiece at at least one position.

[0013] In some embodiments, the controller is further configured to control the airflow channel via a control switch, the control switch including a first switch and a second switch, the airflow channel including: a first channel, one end of which is connected to the containment space and the other end of which is connected to a positive pressure gas source, so that the first channel is used for supplying gas, and the first switch is disposed on the first channel; and a second channel, one end of which is connected to the containment space and the other end of which is connected to a vacuum generator, so that the second channel is used for evacuating gas, and the second switch is disposed on the second channel.

[0014] This application also provides an assembly method for assembling a workpiece onto a flexible component, the flexible component having a through groove, the workpiece being assembled within the through groove, the assembly method comprising: providing an assembly device, the assembly device including a base; placing the flexible component onto the base, the workpiece being configured with the flexible component and the base to form a receiving space; moving the workpiece toward the flexible component via a transfer mechanism; supplying air to the receiving space to expand the flexible component so that the workpiece is assembled with the flexible component; and evacuating air from the receiving space to depressurize the receiving space, thereby causing the flexible component to conform to the workpiece.

[0015] When assembling a workpiece onto a flexible component using the above assembly method, an assembly device is provided, which includes a base and a transfer mechanism. The flexible component is placed on the base, and the workpiece, the flexible component, and the base form a receiving space. The transfer mechanism drives the workpiece to move toward the flexible component. Before the workpiece comes into contact with the flexible component, air is supplied to the receiving space to expand the flexible component so that the workpiece can be assembled with the flexible component. After the workpiece is assembled inside the flexible component, air is extracted into the receiving space to reduce the pressure in the receiving space, thereby causing the flexible component to fit against the workpiece.

[0016] The assembly method provided in this application allows the workpiece to be inserted into the flexible component while it is stretched, reducing friction between the workpiece and the sides of the flexible component. This facilitates easier assembly of the workpiece into the flexible component, increasing the speed of assembly and improving efficiency. Furthermore, since the workpiece is inserted into the flexible component while it is stretched, the probability of damage to the workpiece and flexible component during assembly is reduced, ensuring workpiece quality and extending the service life of the flexible component. The evacuation of air from the receiving space allows the flexible component to better conform to the workpiece, improving the yield rate of workpiece assembly. Additionally, the evacuation of air from the receiving space removes excess gas or creates a vacuum environment, reducing the impact of gas on injection molding yield and improving injection molding quality.

[0017] In some embodiments, prior to the step of evacuating the receiving space to depressurize the receiving space and thereby causing the flexible element to conform to the workpiece, the assembly method further includes: sensing the pressure when the transfer mechanism assembles the workpiece onto the flexible element using a pressure sensor; and controlling the transfer mechanism to loosen the workpiece based on the pressure sensed by the pressure sensor reaching a preset pressure range.

[0018] In some embodiments, the assembly method further includes: stopping air supply and starting air extraction based on the pressure sensed by the pressure sensor reaching a preset pressure range.

[0019] In some embodiments, the assembly method further includes stopping the air supply when the transfer mechanism reaches a preset position. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0066] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0067] Please see Figure 1 This application provides an assembly device 100 in some embodiments. The assembly device 100 is used to assemble a workpiece 200 onto a flexible member 300. The flexible member 300 has a through groove 302, within which the workpiece 200 is assembled. The flexible member 300 is annular in shape, made of silicone material, and the flexible member 300 and the workpiece 200 are in an interference fit. The workpiece 200 can be an object such as a glass panel. Please refer to the accompanying documentation. Figure 2 The assembly equipment 100 includes a base 10, an airflow channel, and a transfer mechanism 20.

[0068] Specifically, the base 10 is used to place the flexible component 300. After the flexible component 300 is placed on the base 10, the base 10, the flexible component 300, and the workpiece 200 enclose a receiving space 400. An airflow channel is connected to the receiving space 400 and is used to supply air to the receiving space 400 to expand the flexible component 300. A transfer mechanism 20 is disposed relative to the base 10. The transfer mechanism 20 is used to move the workpiece 200 toward the flexible component 300 on the base 10 to place the workpiece 200 within the expanded flexible component 300. The transfer mechanism 20 provides power for the assembly of the workpiece 200. The airflow channel is also used to evacuate air from the receiving space 400 to make the flexible component 300 conform to the workpiece 200.

[0069] It should be noted that the receiving space 400 varies depending on the extent to which the workpiece 200 is assembled onto the flexible member 300. For example, the receiving space 400 before the workpiece 200 abuts against the flexible member 300 can be referenced. Figure 2 The S1 region shown, the receiving space 400 within the flexible component 300 where the workpiece 200 is embedded can be referenced. Figure 3 The S2 region shown, the receiving space 400 after the workpiece 200 is implanted into the flexible component 300, can be referenced. Figure 4 The S3 region shown is only a cross-sectional schematic of the containment space 400, while regions S1, S2, and S3 are merely schematic cross-sections. Figures 2 to 4 The middle section is a sectional view.

[0070] When the above-mentioned assembly equipment 100 is in use, firstly, the transfer mechanism 20 drives the workpiece 200 to move toward the flexible part 300 on the base 10. Please refer to the following: Figure 2 Before the workpiece 200 abuts against the flexible member 300, for example, when the workpiece 200 reaches a predetermined position above the flexible member 300, the airflow channel is used to deliver air to the receiving space 400. The air pressure in the receiving space 400 increases, causing the flexible member 300 to be expanded. Please refer to [reference needed]. Figure 3 The transfer mechanism 20 is based on the flexible element 300 being expanded to facilitate the insertion of the workpiece 200 into the flexible element 300. Please refer to [reference needed]. Figure 4 The transfer mechanism 20 inserts the workpiece 200 into the flexible component 300 until the workpiece 200 contacts the base 10. The airflow channel can also evacuate the receiving space 400 to reduce the pressure in the receiving space 400, thereby allowing the flexible component 300 to fit better onto the workpiece 200. In this way, the action of assembling the workpiece 200 onto the flexible component 300 is completed.

[0071] Thus, in order to facilitate the assembly of workpiece 200 into flexible component 300 and improve the assembly efficiency of workpiece 200 and flexible component 300, the assembly equipment 100 provided in this application utilizes the elastic deformation characteristics of flexible component 300. Through the cooperation between base 10, airflow channel and transfer mechanism 20, workpiece 200 can be inserted into flexible component 300 while it is being stretched open. This reduces friction between the side of workpiece 200 and flexible component 300, making it easier for workpiece 200 to be assembled into flexible component 300. This increases the speed of workpiece 200 assembly into flexible component 300, improves the success rate of workpiece 200 insertion, and helps to improve assembly efficiency. Furthermore, since the workpiece 200 is inserted into the flexible component 300 while the flexible component 300 is stretched, the probability of damaging the workpiece 200 and the flexible component 300 during assembly is reduced. This helps ensure the quality of the workpiece 200 and extend the service life of the flexible component 300, reducing the frequency of replacing molds such as the flexible component 300 and increasing the uptime of molds such as the flexible component 300. Since the airflow channel also evacuates the receiving space 400, the flexible component 300 fits better against the workpiece 200, which helps improve the yield of the workpiece 200 assembled with the flexible component 300. Since the airflow channel evacuates the receiving space 400, it can also remove excess gas in the receiving space 400 or create a vacuum environment in the receiving space 400. During injection molding, this reduces the impact of gas on the injection molding yield and helps improve the injection molding quality.

[0072] In this embodiment, the base 10 and the flexible component 300 can be an integral structure. The base 10 can be made of glass, and the flexible component 300 is connected to the base 10 by injection molding. The base 10 has a racetrack structure, and the racetrack of the base 10 can be a planar structure. Thus, after the workpiece 200 is assembled with the flexible component 300, the required structure can be injection molded in the area of ​​the workpiece 200 not covered by the base 10. It is understood that in other embodiments, channels can also be formed on the racetrack of the base 10. Thus, after the workpiece 200 is assembled with the flexible component 300, the required structure can be injection molded in the area of ​​the workpiece 200 covered by the base 10 using the channels of the base 10. The specific design can be set according to the actual situation, and this application does not limit it.

[0073] In this embodiment, the assembly equipment 100 further includes a fixture 50 and an assembly platform 60. The fixture 50 is used to house the base 10, and the assembly platform 60 is used to house the fixture 50. The fixture 50 is mounted on the assembly platform 60, and the base 10 is mounted on the fixture 50. The fixture 50 is provided with a gas connector 52 communicating with the receiving space 400 and the airflow channel. The airflow channel is connected to the receiving space 400 through the gas connector 52. Thus, after the flexible component 300 is implanted into the workpiece 200, the receiving space 400 can be transformed into a closed space using the fixture 50. After the airflow channel is evacuated, the receiving space 400 can form a vacuum environment. Injection molding under vacuum conditions can avoid defects such as insufficient glue, incomplete filling, etc., caused by the presence of gas in the receiving space 400. Furthermore, the base 10 can also be the base of the fixture 50, and the base 10 can be an integral part of the fixture 50.

[0074] In this embodiment, the assembly equipment 100 further includes a pressure sensor 30 and a controller (not shown). The pressure sensor 30 is disposed on the transfer mechanism 20 and is used to detect the pressure applied by the transfer mechanism 20 when assembling the workpiece 200 onto the flexible component 300. The controller is coupled to the pressure sensor 30 and the transfer mechanism 20, and is used to control the transfer mechanism 20 to release the workpiece 200 based on the pressure sensed by the pressure sensor 30 reaching a preset pressure range. Thus, by setting up the pressure sensor 30 and the controller, the pressure sensor 30 detects the pressure applied by the transfer mechanism 20 when assembling the workpiece 200 onto the flexible component 300 in real time. When the pressure detected by the pressure sensor 30 reaches the preset pressure range, it indicates that the workpiece 200 is properly assembled, and the controller controls the transfer mechanism 20 to release the workpiece 200, preventing the transfer mechanism 20 from continuously moving towards the base and damaging the workpiece 200 and the flexible component 300.

[0075] In some embodiments, the controller is further configured to control the airflow channel via a control switch to supply air to the receiving space 400, or to evacuate the receiving space 400, or to stop supplying air, or to stop evacuating air.

[0076] In some embodiments, the airflow channel is also used to stop air delivery and start air extraction when the pressure sensed by the pressure sensor 30 reaches a preset pressure range, under the control of a control switch. Please refer to [reference needed]. Figure 3 When the transfer mechanism 20 moves the workpiece 200 into the flexible component 300, the receiving space 400 is transformed into a roughly enclosed space by the fixture 50. At this time, the air pressure in the receiving space 400 increases, causing a significant change in the pressure on the workpiece 200. Based on this, it is indicated that the workpiece 200 has been inserted into the flexible component 300. Under the control of the control switch, the airflow channel can stop supplying air to the receiving space 400 and start evacuating the receiving space 400, so that the flexible component 300 fits better against the workpiece 200. Evacuation stops when the air pressure in the receiving space 400 meets the preset air pressure range, or when the air pressure in the receiving space 400 meets the preset air pressure range and is maintained for a preset time.

[0077] In some embodiments, the airflow channel is also used to stop air delivery when the transfer mechanism 20 reaches a preset position, under the control of a control switch. Please refer to [reference needed]. Figure 3 When the transfer mechanism 20 moves the workpiece to a preset position, such as the position when it is just inserted into the flexible component 300, the airflow channel can stop supplying air to the receiving space 400 under the control of the control switch. The preset position can be understood as, for example, the position when the transfer mechanism 20 moves the workpiece 200 down by a specified displacement.

[0078] In some embodiments, the airflow channel is also used to stop air delivery when the pressure sensed by the pressure sensor 30 reaches a predetermined pressure range, under the control of a control switch. Please refer to [reference needed]. Figure 3 When the transfer mechanism 20 inserts the workpiece 200 into the flexible component 300, the receiving space 400 is transformed into a largely enclosed space using the fixture 50. At this time, the air pressure inside the receiving space 400 increases, causing a significant change in the pressure on the workpiece 200. Based on this, it is indicated that the workpiece 200 has been inserted into the flexible component 300, and the airflow channel can stop supplying air to the receiving space 400 under the control of the control switch. The preset pressure range is greater than the predetermined pressure range.

[0079] In some embodiments, the airflow channel is also used to stop air supply under the control of a control switch, based on the air pressure in the receiving space 400 meeting a preset air pressure range. Please refer to [reference needed]. Figure 3When the transfer mechanism 20 moves the workpiece 200 into the flexible component 300, the receiving space 400 changes into a roughly enclosed space using the fixture 50. At this time, the air pressure in the receiving space 400 increases, causing the pressure detected by the air pressure sensor to increase. Based on this, it indicates that the workpiece 200 has been inserted into the flexible component 300, and the airflow channel can stop supplying air to the receiving space 400 under the control of the control switch. The preset air pressure range is either a high pressure value or a slightly high pressure value.

[0080] In some embodiments, the airflow channel is also used to evacuate air based on the pressure sensed by the pressure sensor 30 conforming to a preset pressure range, under the control of a control switch. Please refer to [reference needed]. Figure 4 Before the workpiece 200 is inserted into the flexible component 300 by the transfer mechanism 20 and before the workpiece 200 contacts the base 10, the airflow channel stops supplying air when the pressure sensed by the pressure sensor 30 meets the preset pressure range and / or the air pressure of the receiving space 400 meets the preset air pressure range, under the control of the control switch. The transfer mechanism 20 continues to insert the workpiece 200 while stopping the air supply to the receiving space 400. During this insertion process, the flexible component 300 returns to its natural state. When the workpiece 200 contacts the base 10 and the pressure sensed by the pressure sensor 30 meets the preset pressure range, it indicates that the workpiece 200 has been inserted into place. Under the control of the control switch, the airflow channel can evacuate the receiving space 400 to make the flexible component 300 fit better on the workpiece 200, thereby improving the assembly effect of the workpiece 200 and the flexible component 300.

[0081] In some embodiments, when the workpiece 200 is implanted into the flexible member 300 using the fixture 50, the receiving space 400 is a closed space. The airflow channel is also used to stop pumping air after the air pressure in the receiving space 400 meets a preset air pressure range and is maintained for a preset time, under the control of a control switch. Please refer to [reference needed]. Figure 4 When the workpiece 200 contacts the base 10, the airflow channel evacuates the receiving space 400. On the one hand, this allows the flexible part 300 to fit better against the workpiece 200. On the other hand, it removes the gas from the receiving space 400, so that the receiving space 400 can form a vacuum environment. This can prevent defects such as insufficient glue, incomplete glue, or lack of fullness in the structure required for injection molding due to the presence of gas in the receiving space 400.

[0082] In some embodiments, the airflow channel is also used to stop supplying air and evacuate air when the air pressure in the receiving space 400 meets a preset air pressure range, under the control of a control switch. Please refer to [reference needed]. Figure 3When the transfer mechanism 20 moves the workpiece 200 into the flexible component 300, the receiving space 400 is transformed into a roughly enclosed space by the fixture 50. At this time, the air pressure in the receiving space 400 increases, causing the pressure detected by the air pressure sensor to increase. Based on this, it indicates that the workpiece 200 has been inserted into the flexible component 300. The airflow channel can stop supplying air to the receiving space 400 under the control of the control switch and evacuate the receiving space 400, so that the flexible component 300 contracts to fit better against the workpiece 200, until the air pressure in the receiving space 400 meets the preset air pressure range and the evacuation stops, or until the air pressure in the receiving space 400 meets the preset air pressure range and is maintained for a preset time and the evacuation stops.

[0083] Please refer to the following: Figure 1 and Figure 2 In this embodiment, the transfer mechanism 20 includes a motion component 22 and a gripper 24. The motion component 22 is disposed relative to the base 10, and the gripper 24 is connected to the motion component 22. The gripper 24 is used to grasp the workpiece 200 and, under the drive of the motion component 22, to move the workpiece 200 toward the flexible member 300 on the base 10. A pressure sensor 30 is disposed between the gripper 24 and the motion component 22. Thus, by configuring the transfer mechanism 20 to include the motion component 22 and the gripper 24, the effect of the transfer mechanism 20 moving the workpiece 200 toward the flexible member 300 is achieved. The motion component 22 can be composed of functional modules such as a three-axis linear module or a rotary module. The motion component 22 can also be a robotic arm or other functional mechanism capable of moving the workpiece 200 and providing power.

[0084] Please refer to the following: Figure 5In this embodiment, the motion component 22 includes a connecting plate 221, and the gripper 24 includes a conductor 242, a connecting seat 243, a base plate 244, a first elastic member 245, and a second elastic member 246. The connecting plate 221 is connected to the pressure sensor 30. The conductor 242 is connected to the pressure sensor 30, and a stop portion 2422 is provided radially protruding from the conductor 242. A connecting seat 243 is located on the side of the pressure sensor 30 away from the connecting plate 221 of the motion assembly 22. The connecting seat 243 has a receiving cavity 2432, with a first opening 2436 and a second opening 2438 at both ends. A portion of the conductive member 242 passes through the first opening 2436 and is located within the receiving cavity 2432. A stop portion 2422 divides the receiving cavity 2432 into a first cavity 2433 and a second cavity 2434. The first opening 2436 connects to the first cavity 2433, and the second opening 2438 connects to the second cavity 2434. A base plate 244 connects to the connecting seat 243 and abuts against the second opening 2438. The side of the base plate 244 away from the conductive member 242 is used to connect negative pressure to adsorb the workpiece 200. The first elastic element 245 is sleeved on the conductor 242 and located in the first cavity 2433, and the second elastic element 246 is sleeved on the conductor 242 and located in the second cavity 2434. Both the first elastic element 245 and the second elastic element 246 are in a compressed state.

[0085] Thus, by incorporating the first elastic element 245 and the second elastic element 246, the gripper 24 ensures that it does not sway up and down during rapid movement. Furthermore, since the first elastic element 245 and the second elastic element 246 are located in different cavities in the vertical direction (the direction of movement of the gripper 24), at the moment the gripper 24 contacts the flexible component, the elastic force of the first elastic element 245 counteracts the weight of the entire mechanism consisting of the conductor 242, connecting seat 243, base plate 244, and the first and second elastic elements 246 below the pressure sensor 30. This allows for real-time monitoring of the pressure value from zero during implantation and provides the gripper 24 with a certain buffer stroke, preventing damage to the workpiece 200 in case of an anomaly. The first elastic element 245 and the second elastic element 246 can be springs with different elastic coefficients. Obviously, the first elastic element 245 and the second elastic element 246 can also be other functional objects with elasticity. The base plate 244 and the connecting plate 221 are also connected by a guide element 247 and a linear bearing to prevent relative wobbling between the base plate 244 and the connecting plate 221.

[0086] In one embodiment, to detect the adsorbed workpiece 200, the gripper 24 further includes two distance sensors 248. Both distance sensors 248 are connected to the connecting plate 221 of the motion component 22. The two distance sensors 248 are respectively connected to opposite sides of the connecting plate 221 and are arranged diagonally. The two distance sensors 248 are used to detect the adsorbed workpiece 200 at two positions. Thus, by setting the distance sensors 248, on the one hand, the adsorbed workpiece 200 can be detected to determine whether it has been adsorbed or detached from the workpiece 200; on the other hand, the two distance sensors 248 can detect whether the workpiece 200 is in flat contact with the base 10. When the distance values ​​detected by the two distance sensors 248 are different, it indicates that there is a relative tilt between the workpiece 200 and the flexible component 300 or the base 10, which facilitates timely adjustment of the workpiece 200. Obviously, in other embodiments, the gripper 24 may include more or fewer distance sensors 248, such as one, three or more. The specific number and placement can be set according to the actual situation, and this application does not limit this.

[0087] Please see Figure 6 In this embodiment, the airflow channel 40 includes a first channel 41 and a second channel 42, and the control switches include a first switch 45 and a second switch 46. One end of the first channel 41 is connected to the containment space 400 via a gas connector 52, and the other end of the first channel 41 is connected to a positive pressure gas source 43, so that the first channel 41 is used to supply gas to the containment space 400. The first switch 45 is disposed on the first channel 41 and is used to control the on / off state of the first channel 41. One end of the second channel 42 is connected to the containment space 400 via a gas connector 52, and the other end of the first channel 41 is connected to a vacuum generator 44, so that the second channel 42 is used to evacuate the containment space 400. The second switch 46 is disposed on the second channel 42 and is used to control the on / off state of the second channel 42. Pressure sensors can be installed on both the first channel 41 and the second channel 42, and the positive pressure gas source 43 is also used to connect to the vacuum generator 44. Thus, by setting the airflow channel 40 to include a first channel 41 and a second channel 42, the airflow channel 40 can achieve the effect of supplying and evacuating air to the receiving space 400; by setting the first switch 45 and the second switch 46, the airflow channel 40 can achieve the effect of supplying and evacuating air simultaneously by setting a positive pressure air source 43, which helps to save the positive pressure air source 43; the first switch 45 and the second switch 46 can switch between supplying and evacuating air in a timely manner, and the first switch 45 and the second switch 46 can be on / off solenoid valves.

[0088] In this embodiment, the airflow channel 40 further includes a third switch 47, which is located in the first channel 41 and is used to control the gas flow rate within the first channel 41 to adjust the gas pressure in the receiving space 400 during gas delivery, preventing excessive gas pressure in the receiving space 400 from damaging the flexible component 300. Thus, by providing the third switch 47, the gas pressure in the receiving space 400 during gas delivery can be adjusted to suit different assembly requirements. The third switch 47 can be an electro-proportional valve.

[0089] When the aforementioned airflow channel 40 is in use, if it is necessary to supply air to the containing space 400, the positive pressure air source 43, the first switch 45, and the third switch 47 are opened, while the vacuum generator 44 and the second switch 46 are closed, thereby supplying air to the containing space 400. The air pressure within the containing space 400 can be adjusted via the third switch 47. If it is necessary to evacuate air from the containing space 400, the positive pressure air source 43, the vacuum generator 44, and the second switch 46 are opened, while the first switch 45 and the third switch 47 are closed, thereby evacuating air from the containing space 400.

[0090] Understandably, in other embodiments, the third switch 47 may also be omitted.

[0091] Understandably, in other embodiments, an interference portion may be provided protruding on the inner surface of the flexible member, which allows the flexible member and the workpiece 200 to be in an interference fit. When the inner surface of the flexible member is provided with an interference portion, the workpiece 200 can also be assembled onto the flexible member with the interference portion using the assembly equipment 100 provided in the above embodiments, which will not be described in detail in this application.

[0092] Please see Figure 7 This application also provides a flowchart of an assembly method in some embodiments. This assembly method is used to assemble a workpiece onto a flexible member. The flexible member has a through groove, and the workpiece is assembled within the through groove. This assembly method can be implemented by the assembly equipment 100 provided in the above embodiments, or by equipment substantially identical to the assembly equipment 100 provided in the above embodiments. Depending on different requirements, the order in this flowchart can be changed, and some steps can be omitted. For ease of explanation, only the parts relevant to some embodiments of this application are shown. This assembly method includes the following steps S10-S50.

[0093] Step S10: Provide an assembly device, which includes a base and a transfer mechanism 20.

[0094] Specifically, an assembly device 100 as described in the above embodiments is provided. The assembly device 100 includes a base 10 for placing the flexible component 300. Understandably, the assembly device 100 also includes a jig 50, an assembly platform 60, and other mechanisms.

[0095] Step S20: Place the flexible component onto the base, and the workpiece is used to form a receiving space with the flexible component and the base.

[0096] Specifically, the flexible component 300 is placed on the base 10, and the transfer mechanism 20 grabs the workpiece 200 and positions it above the flexible component 300. The workpiece 200, the flexible component 300, and the base 10 enclose a receiving space 400.

[0097] Step S30: The workpiece is moved toward the flexible part by the transfer mechanism.

[0098] Specifically, the transfer mechanism 20 drives the workpiece 200 to move toward the flexible part 300 on the base 10.

[0099] Step S40: Air is supplied to the receiving space to expand the flexible component so that the workpiece can be assembled with the flexible component.

[0100] Specifically, the transfer mechanism 20 moves the workpiece 200 toward the flexible member 300 on the base 10. Before the workpiece 200 comes into contact with the flexible member 300, for example, when the workpiece 200 reaches a predetermined position above the flexible member 300, the airflow channel 40 of the assembly equipment 100 sends air to the receiving workpiece 200, and the air pressure in the receiving space 400 increases, causing the flexible member 300 to be expanded. The transfer mechanism 20 of the assembly equipment 100, based on the expansion of the flexible member 300, makes it easier to insert the workpiece 200 into the flexible member 300, so as to complete the assembly of the workpiece 200 and the flexible member 300.

[0101] Step S50: Air is drawn into the receiving space to depressurize the receiving space, thereby causing the flexible part to conform to the workpiece.

[0102] Specifically, using the assembly equipment 100 provided in the above embodiment, the airflow channel 40 draws air into the receiving space 400 to reduce the pressure in the receiving space 400, thereby allowing the flexible part 300 to fit better onto the workpiece 200.

[0103] Thus, the assembly method provided in this application enables the workpiece 200 to be inserted into the flexible member 300 when the flexible member 300 is stretched open, reducing the friction between the workpiece 200 and the side of the flexible member 300. The workpiece 200 can be assembled into the flexible member 300 more easily, thereby increasing the speed of the workpiece 200 being assembled into the flexible member 300, increasing the success rate of the workpiece 200 being inserted, and improving the assembly efficiency. Furthermore, since the workpiece 200 is inserted into the flexible component 300 while the flexible component 300 is stretched, the probability of damaging the workpiece 200 and the flexible component 300 during assembly can be reduced. This helps ensure the quality of the workpiece 200 and extend the service life of the flexible component 300, reducing the frequency of replacing molds such as the flexible component 300 and increasing the uptime of the molds such as the flexible component 300. Additionally, since air is drawn into the receiving space 400, the flexible component 300 fits better onto the workpiece 200, which helps improve the yield of the workpiece 200 assembled into the flexible component 300. Furthermore, drawing air into the receiving space 400 can also remove excess gas or create a vacuum environment within the receiving space 400, reducing the impact of gas on the injection molding yield during injection molding operations and improving injection molding quality.

[0104] In some embodiments, before performing step S50, the assembly method may also perform the following steps S42-S44.

[0105] Step S42: The pressure of the transfer mechanism assembling the workpiece onto the flexible part is sensed by a pressure sensor.

[0106] Step S44: Based on the pressure sensed by the pressure sensor reaching a preset pressure range, the transfer mechanism is controlled to release the workpiece.

[0107] Thus, by executing steps S42-S44, when the transfer mechanism 20 assembles the workpiece 200 onto the flexible component 300, the pressure sensor 30 senses the pressure of the transfer mechanism 20 so that the workpiece 200 can be released in time after being implanted, thus avoiding damage to the workpiece 200 and the flexible component 300 due to the continuous movement of the workpiece 200 by the transfer mechanism 20.

[0108] In some embodiments, the assembly method may also perform the following step S46 before performing step S50.

[0109] Step S46: Based on the pressure sensed by the pressure sensor reaching the preset pressure range, stop supplying air and start pumping air.

[0110] Specifically, by executing step S44, when the transfer mechanism 20 drives the workpiece 200 into the flexible component 300, the receiving space 400 is transformed into a generally closed space using the fixture 50. At this time, the air pressure in the receiving space 400 increases, causing a significant change in the pressure sensed by the sensor. Based on this, it indicates that the workpiece 200 has been implanted into the flexible component 300. The airflow channel 40 can stop supplying air to the receiving space 400 and start evacuating air from the receiving space 400, so that the flexible component 300 fits better against the workpiece 200. Evacuation stops when the air pressure in the receiving space 400 meets the preset air pressure range, or when the air pressure in the receiving space 400 meets the preset air pressure range and is maintained for a preset time.

[0111] In some embodiments, the assembly method may also perform the following step S48 before performing step S50.

[0112] Step S48: Stop air supply when the transfer mechanism reaches the preset position.

[0113] Specifically, when the transfer mechanism 20 moves the workpiece to a preset position, such as the position when it is just inserted into the flexible component 300, the airflow channel can stop supplying air to the receiving space 400.
