Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing, and more particularly to a vehicle body assembly device. Background Technology

[0002] During the vehicle manufacturing process, body panels need to be assembled with the vehicle body frame. When assembling body panels to the vehicle body frame, the body panels need to be accurately positioned. This requires the body assembly equipment to move and position the body panels to the predetermined location.

[0003] When the assembly equipment moves the cover to the vicinity of the frame, it may cause the cover to collide with the frame, resulting in damage to the cover. Summary of the Invention

[0004] This invention provides a vehicle body assembly device for addressing how to reduce the likelihood of collisions between body panels and the frame.

[0005] This invention provides a vehicle body assembly device, comprising: a base; a transmission system movably connected to the base; a floating system connected to the transmission system; and a clamping member for clamping the cover, wherein the clamping member is connected to the floating system; wherein the floating system includes a connector and a floating air passage, the clamping member is fixedly connected to the connector, and the floating air passage is used to apply air pressure to opposite sides of the connector in at least one direction to restrict the relative movement of the connector and the transmission system.

[0006] Furthermore, the floating system also includes a switching component disposed in the floating air path, used to switch the floating air path between a fixed state and a floating state. When the floating air path is in the fixed state, the floating air path applies a first pressure to the connector. When the floating air path is in the floating state, the floating air path applies a second pressure to the connector, the second pressure being less than the first pressure.

[0007] Furthermore, the switching component includes a pressure relief valve and a controller. The pressure relief valve is located in the floating gas path, and the controller is used to control the opening and closing of the pressure relief valve.

[0008] Furthermore, the switching component includes a drive unit that is connected to the floating air path and is capable of changing the air pressure within the floating air path.

[0009] Furthermore, the assembly equipment also includes a distance sensor, which is fixed to the clamping member. The distance sensor is used to obtain the distance between the clamping member and the vehicle body. When the distance is less than a preset distance threshold, the switching component causes the floating air passage to be in a floating state.

[0010] Furthermore, the assembly equipment also includes a positioning pin, which is fixedly connected to the clamping member and protrudes from the clamping member.

[0011] Furthermore, the connector includes a first connector and a second connector, and the floating air path includes a first floating air path and a second floating air path; the first connector is connected to the transmission system, and in a first direction, the first floating air path is used to apply air pressure to opposite sides of the first connector; the second connector connects the first floating air path to the clamping member, and in a second direction, the second floating air path is used to apply air pressure to opposite sides of the second connector; the first direction is perpendicular to the second direction.

[0012] Furthermore, the connector also includes a third connector and a third floating air passage; wherein, the third connector connects the second floating pipe and the clamping member, and in a third direction, the third floating air passage is used to apply air pressure to opposite sides of the third connector, the third direction being perpendicular to the first direction and perpendicular to the second direction.

[0013] Furthermore, the floating system also includes an indicator and an indicator scale, the indicator being fixedly connected to the connector and pointing towards the indicator scale; wherein the extension direction of the indicator scale is parallel to the movement direction of the connector.

[0014] Furthermore, the transmission system includes a guide rail and a movable part. The guide rail is fixed to the base, and the movable part is movably connected to the guide rail. The movable part is capable of sliding in the extension direction of the guide rail. Along the extension direction of the guide rail, one side of the guide rail is close to the vehicle body, and the opposite side of the guide rail is away from the vehicle body. The floating system is connected to the movable part.

[0015] This invention provides a vehicle body assembly device for assembling a body panel onto a vehicle body. The assembly device includes a base, a transmission system, a floating system, and a clamping member. The transmission system is movably connected to the base, the floating system is connected to the transmission system, and the clamping member is used to clamp the body panel and is connected to the floating system. The floating system includes a floating air passage and a connecting member. The connecting member is fixedly connected to the clamping member, and the floating air passage applies air pressure to opposite sides of the connecting member. When the body panel moves to the position of the vehicle body frame and is in contact with the frame, under the force exerted by the frame on the body panel, the connecting member overcomes the air pressure applied by the floating air passage and generates movement relative to the transmission system. This causes the body panel to move to a position that can avoid the frame, thereby reducing the possibility of the door hinge colliding with the frame and causing damage to the door hinge.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0029] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0030] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. The term "connection," unless otherwise specified, includes both direct and indirect connections.

[0031] In the following specific embodiments, the vehicle body assembly equipment can be applied to the assembly of any automotive body panel. An automotive body panel refers to a surface or internal part made of a thin metal sheet that covers the engine, chassis, and forms the cab and body, and has a spatial shape. The assembly equipment can be used to assemble any type of body panel, such as a fender, engine hood, and door. For ease of explanation, the following uses the assembly equipment for assembling a door hinge as an example to illustrate the structure and function of the assembly equipment.

[0032] In some embodiments, such as Figure 1 As shown, the assembly equipment 1 includes a base 100, a transmission system 200, a floating system 300, and a clamping member 400. The base 100 serves as the fixed foundation for the assembly equipment 1, used to fix other structures of the assembly equipment. The base 100 is located on one side of the workstation used to place the skeleton, providing a reference positioning for the assembly equipment 1. The transmission system 200 is movably connected to the base 100, allowing it to move relative to the base 100. The transmission system 200 is also connected to the clamping member 400, thereby driving the clamping member 400 to move relative to the base 100 and the skeleton located on one side of the base. The clamping member 400 is used to clamp the door hinge, and the clamping member 400 is connected to the transmission system 200. It can move relative to the base 100 under the drive of the transmission system 200, thereby transporting the door hinge to the required assembly position. The transmission system 200 can be any structure that can move relative to the base 100. For example, the transmission system 200 can be a robotic arm that is movably connected to the base. For example, the transmission system 200 can include a slide and a slider. The slide is fixedly connected to the base 100, and the slider can slide relative to the slide.

[0033] like Figure 2 As shown, the floating system 300 connects the clamping member 400 and the transmission system 200. The floating system 300 allows the clamping member 400 to float relative to the transmission system 200 within a certain range under the action of external force. When the clamping member 400 drives the door hinge to move to a position close to the frame, if the door hinge comes into contact with the frame, the floating system 300 can cause the clamping member 400 to move relative to the transmission system 200 under the action of the force exerted by the frame on the door hinge, thereby moving the door hinge to a position that can avoid the frame, reducing the possibility of the door hinge colliding with the frame and thus being damaged.

[0034] The structure of the floating system 300 and the principle that allows the clamping member 400 to move relative to the transmission system 200 are explained below, such as... Figure 3As shown, the floating system 300 includes a connector 310 and a floating air passage 320. The clamping member 400 is fixedly connected to the connector 310. The floating air passage 320 is used to apply air pressure to opposite sides of the connector 310 in at least one direction to restrict the connector 310 relative to... Figure 2 The relative movement of the transmission system 200, i.e., the connecting member 310 connects the transmission system 200 and the clamping member 400, the floating air passage 320 is used to apply air pressure to the opposite sides of the connecting member 310, and the air pressure applied to the connecting member 310 on both sides is the same. When the clamping member 400 is not subjected to external force, the connecting member 310 can stop at the equilibrium position under the action of the air pressure on both sides, and the air pressure restricts the movement of the connecting member 310 and the clamping member 400 relative to the transmission system 200, thereby restricting the movement of the clamping member 400 relative to the transmission system 200 during the movement driven by the transmission system 200, thereby improving the positional accuracy of the clamping member 400 during the movement; when the transmission system 200 moves the clamping member 400 and the door hinge to a position close to the frame, if the door hinge and the frame are in contact, and When the force exerted by the frame on the door hinge is parallel to the direction of the air pressure applied by the floating pipe 320 and is greater than the pressure applied by the floating pipe 320 on the connector 310, the connector 310 can drive the clamping member 400 to overcome the air pressure applied by the floating pipe 320 under the action of external force. This allows the connector 310 and the clamping member 400 to move relative to the transmission system 200, thereby enabling the door hinge to avoid the frame. Moreover, during the movement of the connector 310 relative to the transmission system 200, the volume on one side of the floating pipe 320 is compressed and the volume on the other side is expanded, resulting in a larger pressure difference within the floating pipe 320 and generating an additional pressure opposite to the direction of the external force. This additional pressure is positively correlated with the displacement of the connector 310, thereby limiting the displacement of the connector 310 within a certain range through this additional pressure. The floating air passage 320 applies air pressure to both sides of the connector 310 in at least one direction. This can be understood as allowing the connector 310 to move relative to the transmission system 200 in at least one direction, thereby making the direction of movement of the connector 310 relative to the transmission system 200 more free and further reducing the possibility of the door hinge colliding with the frame.

[0035] This invention provides a vehicle body assembly device for assembling a body panel onto a vehicle body. The assembly device includes a base, a transmission system, a floating system, and a clamping member. The transmission system is movably connected to the base, the floating system is connected to the transmission system, and the clamping member is used to clamp the body panel and is connected to the floating system. The floating system includes a floating air passage and a connecting member. The connecting member is fixedly connected to the clamping member, and the floating air passage applies air pressure to opposite sides of the connecting member. When the body panel moves to the position of the vehicle body frame and is in contact with the frame, under the force exerted by the frame on the body panel, the connecting member overcomes the air pressure applied by the floating air passage and generates movement relative to the transmission system. This causes the body panel to move to a position that can avoid the frame, thereby reducing the possibility of the door hinge colliding with the frame and causing damage to the door hinge.

[0036] In some embodiments, such as Figure 3 As shown, the floating system 300 also includes a switching component 330, which is disposed in the floating air passage 320. The switching component 330 is used to switch the floating air passage 320 between a fixed state and a floating state. When the floating air passage 320 is in the fixed state, the air pressure applied to the connector by the floating air passage 320 is a first pressure. When the floating air passage 320 is in the floating state, the air pressure applied to the connector by the floating air passage is a second pressure, which is less than the first pressure. This can be understood as follows: when it is necessary to lock the connector 310 relative to the transmission system 200, the switching component 330 keeps the floating air passage 320 in a fixed state. That is, the floating air passage 320 applies a greater atmospheric pressure to the opposite sides of the connector 310. This greater air pressure locks the connector 310 and the clamping member 400 in a balanced position, making it more difficult for the external force applied to the clamping member 400 to overcome this air pressure and making it difficult for the connector 310 and the clamping member 400 to move relative to the transmission system 200. Figure 2 The transmission system 200 moves; when it is necessary for the connector 310 and the clamping member 400 to move relative to the transmission system 200, the floating air passage is made to float by the switching component 330, that is, a smaller air pressure is applied to the connector 310 through the floating air passage 320, so that the external force applied to the clamping member 400 can more easily overcome the air pressure applied to the connector 310 by the floating air passage 320, and the connector 310 and the clamping member 400 can move relative to the transmission system 200.

[0037] By setting a switching component 330 in the floating air passage 320, the air pressure in the floating air passage 320 can be actively controlled, thereby allowing the air pressure in the floating air passage 320 to be switched as needed. Specifically, when the cover held by the clamping member 400 is located in a position where the possibility of collision with the frame is low, the switching component 330 can keep the floating air passage 320 in a fixed state, allowing the floating air passage 320 to apply greater air pressure to the connecting member 310, making it difficult for the clamping member 400 to move relative to the transmission system 200 under the action of external force, thus improving the positional accuracy of the clamping member 400 during movement. When the cover held by the clamping member 400 is located in a position where the possibility of collision with the frame is high, the switching component 330 can keep the floating air passage 320 in a floating state, allowing the floating air passage 320 to apply less air pressure to the connecting member 310, thus making it easier for the clamping member 400 to move relative to the transmission system 200 under the action of external force, reducing the possibility of the cover held by the clamping member 400 colliding with the frame.

[0038] The following is an exemplary description of the principle by which the switching component 330 controls the air pressure in the floating air path 320. It should be noted that the structures of the following two switching components are merely illustrative examples. Those skilled in the art should understand that, in addition to the structures of the following two switching components, there are other structures that can achieve the function of the switching component.

[0039] like Figure 4 As shown, the first type of switching component 330A includes a pressure relief valve 331 and a controller 332. The pressure relief valve 331 is disposed in the floating air passage 320. The controller 332 is used to control the opening and closing of the pressure relief valve 331. When the floating air passage 320 needs to be in a fixed state, the controller 332 controls the pressure relief valve 331 to be in a closed state, thereby making the air pressure in the floating air passage 320 a first pressure. When the floating air passage 320 needs to be in a floating state, the controller 332 controls the pressure relief valve 331 to be in a floating state, thereby making the floating air passage... Part of the gas inside 320 can be discharged from the floating gas path 320 through the pressure relief valve 331, thereby reducing the gas pressure in the floating gas path 320 from the first pressure to the second pressure. Optionally, the controller 332 controls the pressure relief valve 331 to open for a preset duration, thereby enabling open-loop control of the gas pressure in the floating gas path 320. Optionally, the switching component 330 also includes a pressure sensor that can acquire the gas pressure in the floating gas path 320. When the gas pressure in the floating gas path 320 drops to the second pressure, the controller 332 controls the pressure relief valve 331 to close. Optionally, the floating gas path 320 is connected to a gas source. After the pressure relief valve 331 closes, the gas in the gas path flows into the floating gas path 320, thereby causing the pressure in the floating gas path 320 to rise from the second pressure back to the first pressure.

[0040] like Figure 5 As shown, the second type of switching component 330B includes a drive member 333, which is connected to the floating air passage 320 and can change the air pressure within the floating air passage 320. Depending on the structure of the drive member 333, the way it changes the air pressure within the floating air passage 320 varies. For example, the drive member 333 is a piston disposed within the floating air passage 320. The movement of this piston can change the volume of the floating air passage 320. Specifically, when the floating air passage 320 needs to be in a fixed state, the piston is controlled to move and compress the volume of the floating air passage 320, thereby compressing the gas within the floating air passage 320 and bringing the air pressure within the floating air passage 320 to a first pressure. When the floating air passage 320 needs to be in a floating state, the piston is controlled to move in a certain direction and increase the volume of the floating air passage 320. This causes the gas in the floating air passage 320 to expand, reducing the air pressure in the floating air passage 320 to a second pressure. For example, the floating air passage 320 is connected to an air source, and the switching component also includes a return air passage connecting the floating air passage 320 and the air source. The gas can circulate within the air source, the floating air passage 320, and the return air passage. The driving member 333 is a blower installed in the floating air passage 320. The blower can control the speed of the gas circulation. When the floating air passage 320 needs to be in a fixed state, the blower is controlled to make the gas circulate at a faster speed, thereby maintaining the air pressure in the floating air passage 320 at a first pressure. When the floating air passage 320 needs to be in a floating state, the blower is controlled to make the gas circulate at a slower speed, thereby reducing the air pressure in the floating air passage 320 to a second pressure.

[0041] The following is an exemplary description of the basis for switching the floating air path 320 by the switching component 330. It should be noted that the switching basis of the following two switching components is only an exemplary description. Those skilled in the art should understand that there are other switching basis besides the following two.

[0042] The first switching method is based on the distance between the clamping component and the frame. Specifically, for example... Figure 6As shown, the assembly equipment also includes a distance sensor 500, which is fixed to the clamping member 400. The distance sensor 500 is used to obtain the distance between the clamping member 400 and the vehicle body. When the distance between the clamping member 400 and the vehicle body is less than a preset threshold, the switching component 330 makes the floating air passage 320 float. That is, the distance between the clamping member 400 and the frame of the vehicle body is used as the switching basis. When the clamping member 400 is far away from the frame of the vehicle body, the possibility of the cover clamped by the clamping member 400 colliding with the frame of the vehicle body is small. Therefore, when the clamping member 400 is far away from the frame of the vehicle body, the floating air passage 320 is fixed. When the clamping member 400 moves to a position close to the frame of the vehicle body, the possibility of the cover clamped by the clamping member 400 colliding with the frame of the vehicle body is large. Therefore, when the clamping member 400 is close to the frame of the vehicle body, the floating air passage 320 is floated.

[0043] The second switching method is based on the position of the clamping component. Specifically, the transmission system also includes a displacement recorder, which can be an encoder disk. The total displacement of the clamping component can be obtained through the displacement recorder. Based on the pre-stored initial position of the clamping component and the total displacement of the clamping component, the theoretical position of the clamping component can be obtained. If the theoretical position is outside the preset area, which is the area close to the frame of the vehicle body, the switching component will fix the floating air path. If the theoretical position is within the preset area, the clamping component is considered to be located close to the frame of the vehicle body, and the switching component will make the floating air path float.

[0044] The following describes the structure of the connector 310, which can connect to the clamping member 400 while maintaining the sealing of the floating air passage 320. Figure 7As shown, the floating air passage 320 has a groove 3201 for the connector 310 to extend out. The extension direction of the groove 3201 is parallel to the extension direction of the floating air passage 320. The connector 310 has a first part located inside the floating air passage 320 and a second part 3102 extending out of the floating air passage 3201. Meanwhile, the groove 3201 has a sliding plate 3301. In the extension direction of the groove 3201, two sliding plates 3301 are located on both sides of the second part 3102. The sliding plates 3301 and the second part 3102 close the groove 3201. The sliding plate 3301 also has an elastic reset member for applying an elastic force to the sliding plate 3301, which enables the sliding plate 3301 to abut against the second part 3102. When the first part slides along the extension direction of the slide groove 3201 under the action of air pressure, the second part 3102 can overcome the elastic force of the elastic reset member, so that the slide plate 3301 on one side moves along the extension direction of the slide groove 3201, and the slide plate 3301 on the other side remains in contact with the second part 3102 under the action of the elastic force of the elastic reset member. That is, the second part 3102 and the slide plate 3301 can maintain the sealing of the floating air passage 320, and at the same time, the connecting member 310 can extend out of the floating air passage 320 and drive the clamping member 400 to move.

[0045] In some embodiments, such as Figure 2 As shown, the assembly equipment 1 also includes a positioning pin 410, which is fixedly connected to and protrudes from the clamping member 400. The positioning pin 410 can cooperate with the positioning hole of the vehicle body frame. That is, the positioning pin 410 can be inserted into the positioning hole to make the cover held by the clamping member 400 reach a preset position. Specifically, the positioning pin 410 protrudes from the clamping member 400 and can protrude from the cover held by the clamping member 400. When the clamping member 400 moves the cover to be close to the vehicle body frame... At the designated position, the positioning pin 410 is located near the positioning hole. In this state, the positioning pin 410 is inserted into the positioning hole. If the positioning pin 410 is not aligned with the positioning hole, the positioning hole will exert a force on the positioning pin 410. Under this force, the floating system 300 allows the clamping member 400 and the positioning pin 410 to move relative to the transmission system 200. Thus, the force between the positioning pin 410 and the positioning hole adaptively positions the cover held by the clamping member 400 to a preset position. This can be understood as follows: the transmission system 200 moves the clamping member 400 to the vicinity of the preset position, achieving coarse positioning of the cover. Simultaneously, the floating system 300 allows the clamping member 400 to move relative to the transmission system 200 under the force between the positioning pin 410 and the positioning hole, achieving adaptive fine positioning of the cover. This reduces the positioning difficulty while improving the positioning accuracy of the cover.

[0046] In some embodiments, such as Figure 8As shown, the connector 310 includes a first connector 311 and a second connector 312, and the floating air passage 320 includes a first floating air passage 321 and a second floating air passage 322; the first connector 311 is connected to the transmission system 200, and in a first direction (the first direction is as shown in the image). Figure 8 (As shown by the solid arrow in the middle), the first floating air passage 321 is used to apply air pressure to the opposite sides of the first connector 311; the second connector 312 connects the first floating air passage 321 and... Figure 2 The clamping member 400 is in the second direction (the second direction is as follows). Figure 8 (As shown by the dashed arrow in the middle), the second floating air passage 422 is used to apply air pressure to the opposite sides of the second connector 412, wherein the first direction and the second direction are perpendicular. It can be understood that by setting two sets of connectors and floating air passages, the clamping member 400 can generate movement relative to the transmission system 200 in the mutually perpendicular first and second directions. Moreover, since the first connector 411 and the second connector 412 are connected, the first connector 411 can move in the first direction and the second connector 412 can move in the second direction, thereby allowing the floating system 300 to allow the clamping member 400 to move in the plane formed by the first and second directions, further improving the degree of freedom of movement of the clamping member 400.

[0047] In some embodiments, such as Figure 8 As shown, connector 310 also includes a third connector 313, and floating air passage 320 also includes a third floating air passage 323. The third connector 313 connects the second floating pipe 322 and the clamping member 400, in the third direction (the third direction is as follows). Figure 8 (As indicated by the dashed arrow), the third floating air passage 323 is used to apply air pressure to the opposite sides of the third connector 313. The third direction is perpendicular to the first direction and perpendicular to the second direction. It can be understood that the floating system 300 allows the clamping member 400 to generate relative pressure in three mutually perpendicular directions. Figure 2 The movement of the transmission system 200 enables the clamping member 400 to move in a three-dimensional space formed by the first direction, the second direction and the third direction, further improving the degree of freedom of movement of the clamping member 400.

[0048] In some embodiments, such as Figure 9As shown, the floating system 300 also includes an indicator 340 and an indicator scale 350. The indicator 340 is fixedly connected to the connector 310, and the indicator 340 points to the indicator scale 350. The extension direction of the indicator scale 350 is parallel to the movement direction of the connector 310. It can be understood that the indicator 340 moves together with the connector 310. The position of the indicator scale 350 pointed to by the indicator 340 can determine the position of the connector 310 in the floating air passage 320. For example, the initial position of the connector 310 needs to be located in the middle position of the floating air passage 320, and the indicator 340 should point to the middle of the indicator scale 350. If the indicator scale 350 does not point to the middle position of the indicator scale 350 when the floating air passage 320 is in a fixed state, it means that the initial position of the connector 310 has shifted. It is necessary to adjust the air pressure on both sides of the connector 310 in the floating air passage 320 to reset the initial position of the connector 310 to the middle position of the floating air passage 320.

[0049] In some embodiments, such as Figure 1 As shown, the transmission system 200 includes a guide rail 210 and a movable part 220. The guide rail 210 is fixed to the base 100, and the movable part 220 is movably connected to the guide rail 210. The movable part 220 can slide in the extending direction of the guide rail 210. Along the extending direction of the guide rail 210, one side of the guide rail 210 is close to the vehicle body, and the other side of the guide rail 210 is away from the vehicle body. This can be understood as the movable part 220 sliding along the extending direction of the guide rail 210, which can move the clamping member 400 closer to the vehicle body. The floating system 300 is fixedly connected to the movable part 220, which includes a working station and a resting station away from the vehicle body. This allows the clamping part 400 to move between a position close to the vehicle body and a position away from the vehicle body. For ease of explanation, the position close to the vehicle body will be referred to as the working station, and the position away from the vehicle body will be referred to as the resting station. The assembly personnel can connect the cover to the clamping part 400 at the resting station, and then move the clamping part 400 to the working station via the movable part 220, and further move the clamping part 400 to a preset position to complete the assembly.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
