Technical Field

[0001] This invention relates to the field of automotive manufacturing technology, and in particular to gel curing tooling, methods, and gel curing assemblies adapted to multiple vehicle models. Background Technology

[0002] With the increasing demands of consumers for the range of new energy vehicles and the need for pedestrian protection in collisions in recent years, automakers have tried every means to make the vehicle body lighter, which has led to the emergence of the form of front cover aluminum alloy inner panel + aluminum alloy outer panel.

[0003] The existing production method for the inner and outer panels of the aluminum alloy front cover is as follows: after applying edge-folding adhesive and rolling the edges between the inner and outer panels of the alloy front cover, gel curing equipment for a single vehicle model is used to perform gel curing.

[0004] Because the gel curing equipment is a specialized machine, it is only suitable for producing front covers for a single car model. When the number of car models increases, the entire gel curing equipment must be redesigned and manufactured, the original equipment must be scrapped, and the operating cost is high. Summary of the Invention

[0005] This invention provides a gel curing fixture, method, and gel curing assembly adapted to multiple vehicle models for workpieces, which solves a series of problems caused by the fact that existing gel curing equipment can only be adapted to the production of front covers for a single vehicle model.

[0039] The adjacent parts of the parts to be heated on the workpiece are respectively mounted on the two guide wheels.

[0040] Preferably, the heating chamber of the heating assembly is an opening formed on the heating assembly, and the length of the opening is adapted to the length of the part to be heated of at least two types of vehicle models.

[0041] The part of the workpiece to be heated is inside the opening, and the part to be heated is the position on the outer surface of the workpiece opposite to the point where the edge adhesive is applied.

[0042] Preferably, the common components of each of the common support and clamping mechanisms include a first support component and a first clamping component adapted to at least two types of vehicle models;

[0043] Each of the dedicated components of the dedicated support and clamping mechanisms includes a second support component and a second clamping component adapted to a workpiece of a certain vehicle model.

[0044] Preferably, the gel curing fixture is used to gel cure aluminum alloy sheets that have been coated with edge-folding adhesive and rolled.

[0048] Preferably, the gel-curing assembly adapted to multiple vehicle models further includes:

[0049] The mounting base supports the rotary drive device.

[0050] On the other hand, the present invention also provides a gel curing method for a workpiece, implemented using the aforementioned workpiece gel curing fixture, wherein the workpiece gel curing method includes:

[0051] Step S1: After receiving the vehicle model code of the vehicle to be processed, determine at least one target dedicated component that is compatible with the vehicle model code of the vehicle to be processed from multiple dedicated support clamping mechanisms.

[0052] Step S2: Control at least one target-specific component to switch to its respective preset position;

[0053] Step S3: After identifying that the workpiece placed on the multiple common components and at least one target dedicated component is a vehicle model workpiece to be processed, control the multiple common components and at least one target dedicated component to clamp and assemble the vehicle model workpiece to be processed.

[0054] Step S4: After recognizing that the workpiece of the vehicle model to be processed is assembled in place, control each of the gel curing mechanisms to extend respectively;

[0055] Step S5: After recognizing that each of the gel curing mechanisms has extended into position, control each of the gel curing mechanisms to heat the respective parts of the workpiece to be processed.

[0056] Step S6: When the temperature of the part of the workpiece to be heated is detected to have reached the predetermined temperature, the gel curing mechanism is controlled to stop heating.

[0057] Preferably, the method further includes:

[0058] Step S7: When the gel curing fixture is started, control the flow of coolant to the cooling components of each gel curing mechanism to cool the heating components of each gel curing mechanism.

[0059] Preferably, in step S1, at least one target special component that matches the model code of the vehicle to be processed is identified based on the predetermined correspondence between the model codes of different vehicle models to be processed and the special components on the multiple special support clamping mechanisms.

[0060] Preferably, in step S3, when a signal is received that the sensor matching the vehicle model to be processed is lit, the workpiece placed on the multiple common components and at least one target-specific component is determined to be the vehicle model workpiece to be processed.

[0061] One sensor is matched with one vehicle model to be processed;

[0062] The sensor's mounting position on the gel curing fixture is determined based on the appearance differences between the workpiece to be processed and other workpieces.

[0063] Preferably, in step S4, when a signal is received that all the first indicator lights are lit, it is determined that the vehicle model workpiece to be processed is assembled in place;

[0064] Each cylinder of the common component and each cylinder of the target-specific component are equipped with a first sensor.

[0065] When each first sensor detects that the corresponding cylinder has extended into position, it triggers the first indicator light connected to it to illuminate.

[0066] Preferably, in step S5, when a signal is received that all the second indicator lights are lit, it is determined that each of the gel curing mechanisms has extended into place;

[0067] Each cylinder of the gel curing mechanism is equipped with a second sensor;

[0070] The beneficial effects of this invention are as follows:

[0071] Using the aforementioned gel curing fixture, gel curing treatment can be performed on workpieces from at least two different car models. Since multiple gel curing mechanisms are arranged around the periphery of the workpiece, each mechanism can heat a specific area, thus reducing the power of a single gel curing mechanism, thereby reducing energy consumption and costs. Furthermore, with the reduced power of a single gel curing mechanism, the heated area on the workpiece is also smaller, reducing the risk of annealing of the front cover and ensuring its rigidity. In addition, because the heated area on the workpiece is smaller, the need for circumferential heat insulation material to prevent heating of unintended areas can be eliminated, further reducing material and equipment costs. By directly guiding the heated area of ​​the workpiece into the heating chamber of the heating assembly, which directly heats the gel-curing location, processing efficiency can be improved.

Detailed Implementation

[0090] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0091] This invention provides a gel curing fixture 1 for workpieces, which is mainly used for gel curing aluminum alloy sheets that have been coated with edge-folding adhesive and rolled edges.

[0092] like Figure 1 As shown, the gel curing fixture 1 includes: a controller, multiple common support clamping mechanisms 11, multiple dedicated support clamping mechanisms 17, multiple gel curing mechanisms 12, and a temperature detector 13.

[0093] Each common support clamping mechanism 11 has a common component that is adapted to at least two types of vehicle model workpieces, and each dedicated support clamping mechanism 17 has at least one dedicated component that is adapted to at least one type of vehicle model workpiece.

[0094] After receiving the vehicle model code of the vehicle to be processed, the controller identifies at least one target dedicated component that matches the vehicle model code from multiple dedicated support clamping mechanisms 17; the controller controls at least one target dedicated component to switch to its respective preset position; after recognizing that the workpiece held on multiple common components and at least one target dedicated component is the vehicle model workpiece 14 to be processed, the controller controls multiple common components and at least one target dedicated component to clamp and assemble the vehicle model workpiece 14 to be processed; after recognizing that the vehicle model workpiece 14 to be processed is assembled in place, the controller controls each gel curing mechanism 12 to heat each part of the vehicle model workpiece 14 to be processed; when the temperature detected by the temperature detector 13 at the part of the vehicle model workpiece 14 to be processed reaches the predetermined temperature, the controller controls each gel curing mechanism 12 to stop heating.

[0095] The vehicle model code of the vehicle to be processed is manually entered into the controller by personnel at the start point according to the manufacturing plan.

[0096] Different vehicle models to be processed are matched with different dedicated components. In this embodiment of the invention, at least one target dedicated component that matches the vehicle model code of the vehicle model to be processed can be identified according to the predetermined correspondence between the vehicle model codes of different vehicle models and the dedicated components on the multiple dedicated support clamping mechanisms 17. For example, the predetermined correspondence records that the target dedicated components that match vehicle model code A are the five target dedicated components on five of the dedicated support clamping mechanisms 17 in this embodiment of the invention.

[0097] Therefore, the controller directs these target-specific components to extend into their respective preset positions to await the workpiece. For the shared-specific components and the gel curing mechanism 12, since they are adapted to the workpiece of the vehicle model used, no position adjustment is required.

[0098] For the target-specific component, it is mainly driven by a cylinder to move to the position that supports the workpiece.

[0099] After the workpiece is gripped and placed on the common components and the target dedicated components, the controller needs to identify whether the workpiece is the vehicle model workpiece 14 to be processed. In this embodiment, when the controller receives a signal that the indicator light matching the vehicle model to be processed is lit, it determines that the workpiece gripped on multiple common components and at least one target dedicated component is the vehicle model workpiece 14 to be processed.

[0100] In this embodiment of the invention, one sensor corresponds to one vehicle model to be processed, and the installation positions of the sensors matched to different vehicle models on the gel curing fixture are different. Each sensor is installed on any position on the gel curing fixture that can distinguish between different vehicle models, such as on a target-specific component or a common component, as long as the vehicle model identified by the sensor is correct.

[0101] The sensor is a distance sensor. When the sensor on the target dedicated component or shared component detects that the distance between it and the workpiece meets the set distance, the indicator light on the sensor will light up.

[0102] The controller is pre-installed with vehicle model codes corresponding to different indicator lights. The controller identifies the vehicle model code corresponding to the workpiece based on the illuminated indicator light, and then matches it with the currently input vehicle model code. If the two vehicle model codes match, the workpiece placed on multiple common components and at least one target dedicated component can be identified as the vehicle model workpiece 14 to be processed.

[0103] Once the workpiece placed on the tooling is identified as the vehicle model workpiece 14 to be processed, it needs to be clamped. The controller controls multiple common components and at least one target-specific component to clamp and assemble the vehicle model workpiece 14 to be processed.

[0104] In this embodiment, a first sensor is arranged on the cylinder of each common component and the cylinder of each target special component. When a signal is received that all the first indicator lights are lit, it is determined that the workpiece 14 of the vehicle model to be processed is assembled in place.

[0105] After identifying the vehicle model workpiece 14 to be processed, it is necessary to control the gel curing mechanism 12 to extend into position. The specific extension process of the gel curing mechanism 12 will be described later.

[0106] A second sensor is arranged on the cylinder of each gel curing mechanism. When the controller receives a signal that all the second indicator lights are lit, it determines that each gel curing mechanism 12 has extended into place.

[0107] Therefore, the controller starts to control each gel curing mechanism 12 to heat the workpiece 14 to be processed. During the heating process, the controller can control each gel curing mechanism 12 to stop heating at any time according to the temperature detected by the temperature detector 13.

[0108] In various embodiments of the present invention, the number of temperature detectors 13 is designed according to actual needs. For example, a temperature detector can be arranged near each heating part of the workpiece 14 to be processed, thereby controlling each gel curing mechanism 12 separately and improving control accuracy. To reduce costs, since the temperature change trend at different heating positions is basically the same during the heating process, temperature detectors can be arranged at only one or a few heating parts, and all gel curing mechanisms 12 can be controlled simultaneously based on the collected value of one temperature detector or the average value of several temperature detectors.

[0109] Similarly, the placement of the temperature detector 13 also needs to be designed according to the actual situation of the tooling. The temperature detector 13 is required to collect the actual temperature of the part to be heated as much as possible, without affecting the installation of the various mechanisms on the tooling.

[0110] In various embodiments of the present invention, the vehicle model workpiece 14 to be processed is an aluminum alloy sheet that has been coated with folding adhesive and rolled, such as the door sheet metal, front cover, trunk lid and other structures on a vehicle.

[0111] The workpiece 14, to be processed, has an inner panel and an outer panel. During processing, the edge of the outer panel extends beyond the edge of the inner panel, and the angle of the outer panel's snap-fit ​​edge generally needs to be less than 90°. After applying folding adhesive to the surfaces where the inner and outer panels will be bonded, the edge of the outer panel is rolled and folded towards the inner panel until the edge of the outer panel completely covers the edge of the inner panel. At this point, the folding adhesive is in an uncured state and needs to be gelled and cured.

[0112] While the basic structure of the same part is largely the same across different vehicle models, the specific design details will be adjusted according to the specific model. This embodiment utilizes this characteristic of the part, clamping the common outer shape areas on the aluminum alloy sheet metal parts of various models using a shared component of the shared support clamping mechanism 11, while clamping the specific outer shape areas on the parts of each model using the specific components of the dedicated support clamping mechanism 17. This allows for the use of the same set of gel curing fixture 1 to support and clamp multiple models of workpieces 14 to be processed.

[0113] In this embodiment, a dedicated support clamping mechanism 17 can be designed with two dedicated components, one dedicated component, or even more dedicated components, depending on the requirements. For example, in this embodiment of the invention, some dedicated support clamping mechanisms 17 are designed with only one dedicated component, while others are designed with two dedicated components. This allows the gel curing fixture 1 to be adapted to workpieces from two different vehicle models.

[0114] In this embodiment, in order to facilitate the overall handling and management of multiple support clamping mechanisms 11 and multiple gel curing mechanisms 12, the gel curing fixture 1 may also include a mounting base plate 16, on which multiple common support clamping mechanisms 11, multiple dedicated support clamping mechanisms 17 and multiple gel curing mechanisms 12 are fixed.

[0115] like Figure 2 and Figure 11 The common support clamping mechanism 11 specifically includes: a base; a first support component 111 fixedly installed on the base; and a first clamping component 112 rotatably or telescopically assembled on the base.

[0116] The first support component 111 and the first clamping component 112 together form the common component of the common support and clamping mechanism 11, which can be adapted to workpieces 14 of at least two different car models.

[0117] The first support assembly 111 is used to support the lower surface of the workpiece 14 to be processed; the first clamping assembly 112 is used to clamp the upper surface of the workpiece 14 to be processed.

[0118] The first clamping assembly 112 moves closer to or further away from the upper surface of the workpiece 14 to be processed by rotation. When the first clamping assembly 112 contacts the upper surface of the workpiece 14, the upper and lower surfaces of the workpiece 14 are clamped between the first support assembly 111 and the first clamping assembly 112. Alternatively, the first clamping assembly 112 can directly clamp the part by telescoping.

[0119] In this embodiment of the invention, the first clamping assembly 112 is powered by a cylinder or other power device to achieve extension, rotation and other movements.

[0120] A first sensor is installed on the cylinder of the first clamping assembly 112. The first sensor detects the extension and retraction stroke of the cylinder. When the first sensor detects that the cylinder extension stroke of the first clamping assembly 112 has reached the preset stroke, the first indicator light connected to the first sensor will be lit. When the signal of the first indicator light being lit is received, it is considered that the first clamping assembly 112 is clamped and assembled in place for the workpiece 14 to be processed.

[0121] For example, when the piston moves up and down within the cylinder of the first clamping assembly 112, it causes a change in gas pressure, thereby generating a differential pressure signal. This differential pressure signal is transmitted to the first sensor, converted into an electrical signal, and then output to the first indicator light. When the first indicator light is illuminated, it is considered that the cylinder of the first clamping assembly 112 has extended into position.

[0122] like Figure 2 and Figure 12 The dedicated support and clamping mechanism 17 specifically includes: a base plate; and multiple sets of dedicated components fixedly mounted on the base plate. One set of dedicated components includes a second support component 171 fixedly mounted on the base plate and a second clamping component 172 rotatably or telescopically assembled on the base plate.

[0123] The second support assembly 171 is used to support the lower surface of the workpiece 14 to be processed; the second clamping assembly 172 clamps the upper surface of the workpiece 14 to be processed by rotating, so that the upper and lower surfaces of the workpiece 14 to be processed are clamped between the second support assembly 171 and the second clamping assembly 172, or the second clamping assembly 172 clamps the part directly by telescopic movement.

[0124] In this embodiment of the invention, the second clamping assembly 172 relies on a power device such as a cylinder to output power to achieve movements such as extension, rotation, etc. A first sensor is installed on the cylinder of the second clamping assembly 172. The first sensor detects the extension and retraction stroke of the cylinder. When the first sensor detects that the extension stroke of the cylinder of the second clamping assembly 172 has reached a preset stroke, the first indicator light connected to the first sensor is lit. When the signal of the first indicator light being lit is received, it is considered that the second clamping assembly 172 is clamped and assembled in place for the workpiece 14 to be processed.

[0125] For example, when the piston moves up and down within the cylinder of the second clamping assembly 172, it causes a change in gas pressure, thereby generating a differential pressure signal. This differential pressure signal is transmitted to the first sensor, converted into an electrical signal, and then output to the first indicator light. When the first indicator light is illuminated, it is considered that the cylinder of the second clamping assembly 172 has extended into its proper position.

[0126] like Figures 3 to 6 In order to perform gel curing treatment on the vehicle model workpiece 14 to be processed, which is supported and clamped by the shared support clamping mechanism 11 and the dedicated support clamping mechanism 17, each gel curing mechanism 12 in this embodiment includes: a driving component 121, a floating component 122 driven by the driving component 121, a heating component 123 fixedly connected to the floating component 122, and a guide component 124 fixedly connected to the heating component 123.

[0127] like Figure 13 The controller controls the drive assembly 121 to push the floating assembly 122 and the heating assembly 123 together toward the workpiece 14 to be processed. After the overlapping area of ​​the workpiece 14 to be processed is placed on the guide assembly 124, the guide assembly 124 guides the part of the workpiece 14 to be heated into the heating chamber of the heating assembly 123. At the same time, the guide assembly 124 is subjected to the force of the workpiece 14 to be processed, and floats together with the heating assembly 123 and the floating assembly 122 within the floating space allowed by the floating assembly 122, so that the heating chamber of the heating assembly 123 floats to a state where it is directly opposite the part of the workpiece 14 to be heated.

[0128] After the drive assembly 121 is in position, the controller controls the heating assembly 123 to start heating; when the temperature detected by the temperature detector 13 at the heating part of the workpiece 14 to be processed reaches the predetermined temperature, the controller controls the heating assembly 123 to stop heating.

[0129] In various embodiments of the present invention, the controller outputs control signals to the valve island 15. The valve island is a control component composed of multiple electrically controlled valves, integrating signal input / output and signal control, much like a control island. Each electrically controlled valve in the valve island 15 controls the cylinders of the first clamping assembly 112 in the shared support clamping mechanism 11 and the second clamping assembly 172 in the dedicated support clamping mechanism 17, and also controls the cylinders of the multiple gel curing mechanisms 12. The valve island 15 also transmits signals from indicator lights or sensors to the controller.

[0130] The drive assembly 121 is specifically a cylinder that extends or retracts under the drive control of the valve island 15. When the drive assembly 121 extends, it will drive the floating assembly 122 and the heating assembly 123 to move toward the workpiece 14 to be processed.

[0131] When the second indicator light arranged on the drive assembly 121 of each gel curing mechanism 12 is lit, the controller determines that each gel curing mechanism 12 has extended into position.

[0132] For example, a second sensor is placed on the cylinder of each drive assembly 121 to detect the extension and retraction of the cylinder's stroke. When the piston moves up and down inside the cylinder of the drive assembly 121, it causes a change in gas pressure, generating a differential pressure signal. This differential pressure signal is transmitted to the second sensor, converted into an electrical signal, and output to the second indicator light. When the second indicator light is illuminated, it is considered that the cylinder of the drive assembly 121 has extended to its full position.

[0133] When all the cylinders of the drive assembly 121 have extended into position, it can be assumed that each part of the workpiece 14 to be heated has been inserted into the heating chamber of each gel curing mechanism 12, and heating can be turned on.

[0134] After the heating component 123 starts heating, when the temperature detector 13 detects that the temperature of the part of the workpiece 14 to be processed has reached the predetermined temperature, the controller controls the heating component 123 to stop heating.

[0135] Specifically, when the temperature detected at any heated part of the workpiece 14 to be processed reaches a predetermined temperature, the controller controls the corresponding gel curing mechanism 12 to stop heating; or when the average temperature detected at at least two heated parts of the workpiece 14 to be processed reaches a predetermined temperature, the controller controls all gel curing mechanisms 12 to stop heating.

[0136] The preset temperature is set according to requirements, with the aim of preventing the heating component 123 from being damaged by heat.

[0137] like Figure 3 and Figure 4Each gel curing mechanism 12 further includes a cooling component 125 fixedly connected to the floating component 122; the cooling component 125 is used to cool the heating component 123.

[0138] Coolant is introduced into the cooling component 125. When the control system of the gel curing fixture 1 (including the controller, valve island, etc. in this solution) is powered on and started, the coolant in the cooling component 125 begins to circulate. Regardless of whether the heating component 123 is turned on, the coolant in the cooling component 125 cools the heating component 123.

[0139] like Figure 3 and Figure 4 In order to fix the drive component 121, each gel curing mechanism 12 further includes a support component 127 for fixing the drive component 121, and the support component 127 has a limiting structure.

[0140] When the drive assembly 121 extends to the required working position of the workpiece, the position of the drive assembly 121 is limited by the limiting structure.

[0141] The support component 127 serves two purposes: firstly, it fixes the drive component 121, thereby fixing other components; secondly, it can be used to fix other tooling.

[0142] like Figure 3 and Figure 4 Considering that when the drive component 121 is directly assembled with the floating component 122, it is also necessary to install and debug according to the actual situation of the vehicle model workpiece 14 to be processed. Therefore, an intermediate component 126 is added to facilitate installation and debugging. Different models of vehicle model workpieces 14 to be processed correspond to intermediate components 126 of different thicknesses.

[0143] That is, each gel curing mechanism 12 in the embodiments of the present invention further includes: an intermediate component 126 fixedly connected to the driving component 121; a floating component 122 fixedly connected to the intermediate component 126 through a first connector 1223; after the overlapping area of ​​the vehicle model workpiece 14 to be processed is placed on the guide component 124, the guide component 124 and the heating component 123 float relative to the first connector 1223 together with the floating component 122.

[0144] like Figure 4In this embodiment of the invention, the intermediate component 126 is an adjustable-thickness mounting plate. An arc-shaped hole 1261 is provided on the intermediate component 126, and the intermediate component 126 is screwed to the output end of the drive component 121 using bolts passing through the arc-shaped hole 1261. Due to machining errors in the processing and assembly of different parts, the cumulative error increases after multiple components on the gel curing mechanism 12 are installed sequentially. When the intermediate component 126 is fixed to the output end of the drive component 121, the relative position of the mounting plate and the output end of the drive component 121 can be adjusted (i.e., the installation position of the bolts in the arc-shaped hole 1261) based on the overall cumulative error of the gel curing mechanism 12 at this time, so that the floating component 122 installed with the intermediate component 126 can be quickly adjusted into position during installation. Since the gel curing fixture has multiple gel curing mechanisms 12, each of which has similar processing error problems, the overall installation and debugging time can be reduced by adjusting the installation position of the bolts in the arc-shaped hole 1261 when adjusting the position between the floating component 122 and the driving component 121. For the floating component 122 in this embodiment of the invention, as... Figure 10 Specifically, it includes: a fixed base 1221, which is fixedly connected to the heating component 123 and the cooling component 125; a connecting base 1222, which is installed on the side of the fixed base 1221 facing the intermediate component 126, and the connecting base 1222 is movably equipped with a first connecting member 1223 in the direction facing the intermediate component 126; one end of the first connecting member 1223 is fixedly assembled on the intermediate component 126, and a first elastic member 1224 is fitted on the first connecting member 1223, and the first elastic member 1224 is arranged between the connecting base 1222 and the intermediate component 126; relying on the first elastic member 1224, the guide component 124 and the heating component 123 float back and forth along the first connecting member 1223 together with the fixed base 1221 and the connecting base 1222.

[0145] like Figure 10 The first connector 1223 is a first pin movably mounted on the connector 1222. One end of the first pin is fixed with a nut, and the other end of the first pin is provided with an external thread. A stepped hole is provided on the connector 1222, and the other end of the first pin passes through the stepped hole and is fixedly connected to the intermediate component 126 by the external thread.

[0146] The larger hole in the stepped bore mates with the nut of the first pin, while the smaller hole in the stepped bore positions the nut of the first pin. The threaded portion of the first pin forms a clearance fit with the smaller hole in the stepped bore.

[0147] An internal thread blind hole is provided on the intermediate component 126 to be threaded into the external thread of the aforementioned first pin.

[0148] In addition, the first elastic element 1224 is a spring, which is fitted on the screw of the first pin, specifically located between the connecting seat 1222 and the intermediate component 126. By compressing or stretching the spring, the connecting seat 1222 slides along the stud of the first pin, that is, the connecting seat 1222 slides relative to the intermediate component 126 and the drive component 121.

[0149] When the overlapping area of ​​the workpiece 14 to be processed is placed on the guide assembly 124, the force on the guide assembly 124 is sequentially transmitted to the fixed seat 1221 and then to the connecting seat 1222. The connecting seat 1222 is pushed along the first pin towards the intermediate assembly 126 and compresses the first spring. Figure 6 , Figure 10 and Figure 13 In this embodiment of the invention, the direction in which the connector 1222 is relatively close to the intermediate component 126 is defined as the front, and the direction in which the connector 1222 is away from the intermediate component 126 is defined as the rear.

[0150] like Figure 6 , Figure 10 and Figure 13 Considering that the force exerted on the guide assembly 124 by the workpiece 14 of the vehicle model to be processed is not limited to the aforementioned front-to-back force, but also includes the force in the up-and-down direction due to the overlapping area of ​​the workpiece 14 of the vehicle model to be processed resting on the guide assembly 124. Therefore, as Figure 10 In this embodiment of the invention, a second connecting member 1225 is movably mounted on the connecting seat 1222; one end of the second connecting member 1225 is fixedly mounted on the fixed seat 1221, and a second elastic member is fitted on the second connecting member 1225. The second elastic member is limited in the internal cavity in which the connecting seat 1222 and the second connecting member 1225 are movably assembled. The guide assembly 124 and the heating assembly 123 float up and down relative to the second connecting member 1225 together with the fixed seat 1221 by relying on the second elastic member.

[0151] Specifically, such as Figure 10As shown, a strip plate 1226 is fixedly mounted on the side wall of the connecting seat 1222. One end of the strip plate 1226 is fixedly connected to the connecting seat 1222. A second pin, serving as a second connecting member 1225, is fixedly mounted on the side wall of the fixed seat 1221 near the strip plate 1226. A second spring, serving as a second elastic member, is fitted on the second pin. After the second pin is screwed into a blind hole provided on the side wall of the fixed seat 1221, the second spring is placed in the mounting cavity of the strip plate 1226 that matches the second pin. The assembly method of the second pin between the connecting seat 1222 and the fixed seat 1221 is the same as the connection method of the first pin between the connecting seat 1222 and the intermediate component 126. Thus, when the force of the guide component 124 is sequentially transmitted to the fixed seat 1221, the second spring causes the fixed seat 1221 to float in the vertical direction relative to the connecting seat 1222, thereby causing the heating component 123 to float vertically along with the fixed seat 1221.

[0152] Relying on the aforementioned first and second springs, when the overlapping area of ​​the workpiece 14 to be processed is placed on the guide assembly 124, the floating assembly 122 can drive the heating assembly 123 and the guide assembly 124 to float in the front-back direction and the up-down direction. The specific amount of floating is determined by the force applied to the guide assembly 124 by the workpiece 14 to be processed.

[0153] from Figure 10 In this embodiment, strip plates 1226 are installed on both sides of the connecting seat 1222 and the fixing seat 1221. After the strip plates 1226 and the connecting seat 1222 are assembled, they form a U-shaped cross section.

[0154] like Figure 7 As shown, the guide assembly 124 in this embodiment of the invention includes: two guide seats 1241 and two guide wheels 1242; the two guide seats 1241 are mounted on the symmetrical sides of the heating assembly 123, one guide seat 1241 is rotatably connected to the other guide seat 1241, and the two guide wheels 1242 are symmetrically arranged on both sides of the heating chamber of the heating assembly 123; the adjacent parts of the parts to be heated on the workpiece 14 of the vehicle model to be processed are respectively mounted on the two guide wheels 1242.

[0155] Each guide wheel 1242 is fixedly mounted on the inner side of the corresponding guide seat 1241, and the two guide wheels 1242 are symmetrically arranged. Both guide wheels 1242 can rotate, and the overlap position between the guide wheel 1242 and the surface of the workpiece 14 to be processed is higher than the lower surface of the heating cavity in the heating assembly 123. Thus, when the guide wheel 1242 begins to contact the overlap area of ​​the workpiece 14 to be processed due to the drive of the drive assembly 121, the guide wheel 1242 rotates relative to the workpiece 14 to be processed, thereby sending the part of the workpiece 14 to be heated into the heating cavity of the heating assembly 123, avoiding the problem of the surface of the workpiece 14 being torn.

[0156] like Figure 9 In this embodiment of the invention, the support component 127 of each gel curing mechanism 12 includes: a base 1271, on which a limiting block 1272 is installed; the limiting block 1272 restricts the extension position of the drive component 121.

[0157] in, Figure 9 The limiting block 1272 serves as the aforementioned limiting structure. When the cylinder of the drive assembly 121 extends to the required working position of the workpiece, the limiting block 1272 is used to limit the position of the cylinder of the drive assembly 121.

[0158] In existing technologies, the unreasonable design of the distance between the heating center and the heating part of the front cover in gel curing equipment leads to the following problems: a) The heating center of the gel curing equipment is located on the side edge of the front cover, resulting in a large distance between the folded edge of the front cover and the heating center. In order to heat the folded edge, the gel curing device can only increase the heating power to expand the heating range. Therefore, the rated power of existing gel curing equipment reaches 120KW, resulting in high energy consumption and high operating costs. In addition, if the front cover is placed too close to the heating center of the gel curing equipment, the heating surface on the front cover will increase, making the front cover susceptible to annealing. a) Annealing of the front cover will affect the overall rigidity of the front cover; b) Since the heating part of the front cover is on the side edge, the gel curing time of the two-component folding adhesive is long and the production efficiency is low; c) Since the gel curing equipment increases the heating range by increasing the heating power, in order to avoid heating areas on the front cover that do not need to be heated, the upper and lower surfaces of the front cover need to be shaped and supported by heat insulation material, resulting in high material costs and large equipment investment costs; d) Because the front cover is shaped and heated around the entire circle, the structure is complex, difficult to debug, and inconvenient to maintain. Since it is a series structure, it cannot be heated precisely. If one position fails, the entire equipment will stop and affect production.

[0159] like Figure 8 and Figure 13In this embodiment, the heating cavity of the heating component 123 is an opening 1231 formed on the heating component 123. The length of the opening 1231 is adapted to the length of the heating part of at least two types of vehicle model workpieces 14. The heating part of the vehicle model workpiece 14 to be processed is inside the opening 1231. The heating part is the position on the outer surface of the vehicle model workpiece 14 to be processed that is opposite to the folding adhesive coating point.

[0160] The aforementioned opening 1231 is a U-shaped opening. Heating elements are installed on the upper and lower surfaces of the U-shaped opening of the heating assembly 123. The controller controls the heating elements to heat up directly on the outer surface of the workpiece 14 to be processed in the heating chamber, at the position opposite to the edge adhesive coating point.

[0161] Using the aforementioned gel curing fixture 1 in this embodiment of the invention, since a special component and a common component for supporting and clamping workpieces of different vehicle models are designed, it is possible to support and clamp workpieces 14 of at least two vehicle models to be processed; multiple gel curing mechanisms 12 further heat the supported and clamped workpieces, thereby realizing gel curing of workpieces of various different vehicle models.

[0162] Since multiple gel curing mechanisms 12 are provided around the workpiece 14 to be processed, each gel curing mechanism 12 can directly heat a part to be heated (i.e., the position on the outer surface of the workpiece 14 to be processed that is opposite to the folded adhesive coating point), the power of a single gel curing mechanism 12 can be reduced, thereby reducing energy consumption and lowering costs.

[0163] Furthermore, as the power of a single gel curing mechanism 12 is reduced, the heated area on the workpiece 14 to be processed will also be reduced, which can reduce the risk of front cover annealing and thus ensure the rigidity of the front cover.

[0164] Furthermore, since the heated area on the workpiece 14 is reduced, the need to use heat-insulating material to conform the entire perimeter and prevent areas from being heated can be eliminated, thus reducing material and equipment costs. The part of the workpiece 14 to be heated is directly introduced into the heating chamber of the heating assembly 123, which directly heats the area requiring gel curing, improving processing efficiency.

[0165] Based on the foregoing description, the gel curing fixture 1 in this embodiment can solve the problems caused by the unreasonable distance between the workpiece heating area and the heating center of the gel curing equipment in the prior art, as well as the fact that it can only be adapted to the production of workpieces of a single vehicle model.

[0166] To accommodate more vehicle models, this embodiment of the invention also provides a gel-cured assembly adaptable to multiple vehicle models, such as... Figure 14 and Figure 15The gel curing assembly includes a mounting frame 2, on which the aforementioned gel curing fixture 1 is mounted on at least one mounting surface of the mounting frame 2; and a rotary drive device 3, which drives the mounting frame 2 to rotate, so that the gel curing fixture 1 mounted on one of the mounting surfaces of the mounting frame 2 is rotated to the target position.

[0167] The gel curing fixture 1 is mounted on at least one mounting surface of the mounting frame 2 via the mounting base plate 16.

[0168] The rotary drive device 3 is supported by the mounting base 4. The rotary drive device 3 includes an active end and a driven end mounted on opposite sides of the mounting frame 2. The active end is driven by a hub, and the driven end is a standard bearing housing.

[0169] like Figure 14 and 15 The mounting frame 2 is a hexahedral frame, and a set of the aforementioned gel curing fixture 1 can be installed on each of the four faces of the frame. Thus, the rotary drive device 3 can be used to rotate the set of gel curing fixture 1 on the corresponding mounting face to the gel curing station to achieve gel curing of at least 8 sets of vehicle models to be processed workpieces 14.

[0170] This invention also provides a method for gel curing a workpiece using the aforementioned gel curing fixture. The vehicle model workpiece 14 to be processed has already undergone edge coating and edge rolling treatment. Figure 16 The gel curing method for this workpiece includes:

[0171] Step S1: After receiving the model code of the vehicle to be processed, at least one target dedicated component that is compatible with the model code of the vehicle to be processed is determined from among the multiple dedicated support clamping mechanisms 17.

[0172] Step S2: Control at least one target-specific component to switch to its respective preset position.

[0173] Step S3: After identifying the workpiece placed on multiple common components and at least one target dedicated component as the vehicle model workpiece 14 to be processed, control the multiple common components and at least one target dedicated component to clamp and assemble the vehicle model workpiece 14 to be processed.

[0174] Step S4: After the workpiece 14 of the vehicle model to be processed is identified as being assembled in place, control each gel curing mechanism 12 to extend.

[0175] Step S5: After recognizing that each gel curing mechanism 12 has extended into position, control each gel curing mechanism 12 to heat each part of the workpiece 14 to be processed.

[0176] Step S6: When the temperature of the part to be heated of the workpiece 14 to be processed reaches the predetermined temperature, control each gel curing mechanism 12 to stop heating.

[0177] like Figure 17 The present invention provides a specific process for a gel curing method for a workpiece, including:

[0178] S101, when the gel curing fixture is started, the coolant is controlled to flow into the cooling components 125 of each gel curing mechanism 12 to cool the heating components 123 of each gel curing mechanism 12.

[0179] The start-up of the gel curing fixture refers to the power-on activation of its control system (including the controller, valve island, etc.). After the controller is powered on, the cooling pump of the gel curing fixture is activated, causing the coolant to circulate in the cooling loop. When the coolant flows through the cooling loop to each cooling component 125, it cools the heating components 123 of each gel curing mechanism 12. In this embodiment of the invention, the activation condition for the cooling components is the power-on activation of the control system, which continuously cools the heating components 123 to prevent overheating.

[0180] Step S102: After receiving the model code of the vehicle to be processed, at least one target dedicated component that is compatible with the model code of the vehicle to be processed is determined from among the multiple dedicated support clamping mechanisms 17.

[0181] The controller is pre-installed with vehicle model codes corresponding to different sensors. The controller identifies the vehicle model code corresponding to the workpiece based on the signal fed back by the sensor, and then matches it with the currently input vehicle model code. If the two vehicle model codes match, the workpiece placed on multiple common components and at least one target dedicated component can be identified as the vehicle model workpiece 14 to be processed.

[0182] Different vehicle models to be processed are matched with different special components. In this embodiment of the invention, at least one target special component that matches the vehicle model code of the vehicle model to be processed can be identified according to the vehicle model code of the different vehicle models to be processed and the predetermined correspondence between each special component on the multiple special support clamping mechanisms 17.

[0183] Step S103: Control at least one target-specific component to switch to its respective preset position.

[0184] Step S104: After identifying the workpiece placed on multiple common components and at least one target dedicated component as the vehicle model workpiece 14 to be processed, control the multiple common components and at least one target dedicated component to clamp and assemble the vehicle model workpiece 14 to be processed.

[0185] When the controller receives a signal that the sensor matching the vehicle model to be processed is lit, it determines that the workpiece placed on the plurality of common components and at least one target-specific component is the vehicle model workpiece 14 to be processed.

[0186] In step S105, after the vehicle model workpiece 14 to be processed is identified as being assembled in place, each of the gel curing mechanisms 12 is controlled to extend.

[0187] A first sensor is arranged on the cylinder of each common component and the cylinder of each target special component. When a signal is received that all the first indicator lights are lit, it is determined that the workpiece 14 of the vehicle model to be processed is assembled in place.

[0188] Step S106: After recognizing that each gel curing mechanism 12 has extended into position, control each gel curing mechanism 12 to heat each part of the workpiece 14 to be processed.

[0189] In step S106, a second sensor is arranged on the cylinder of each gel curing mechanism. For the controller, when it receives a signal that all the second indicator lights are lit, it determines that each gel curing mechanism 12 has extended into place.

[0190] Step S107: When the temperature of the part to be heated of the workpiece 14 to be processed reaches the predetermined temperature, control each gel curing mechanism 12 to stop heating.

[0191] In step S107, when the temperature detected at any heated part of the workpiece 14 to be processed reaches a predetermined temperature, the corresponding gel curing mechanism 12 is controlled to stop heating; or

[0192] When the average temperature detected at at least two locations to be heated on the workpiece 14 reaches a predetermined temperature, the entire gel curing mechanism 12 is controlled to stop heating.

[0193] The preset temperature is set according to requirements, with the aim of preventing the heating component 123 from being damaged by heat.

[0194] Using the gel curing method described above, gel curing of a specific model of vehicle model workpiece 14 to be processed was achieved on a set of gel curing fixtures.
