Description

Technical Field

[0001] This utility model relates to the field of sleeve processing technology, and in particular to a thermal expansion adhesive coating assembly device. Background Technology

[0002] In the manufacturing process of the sleeve, heat expansion, adhesive application, and assembly are three important processing steps: the heat expansion process expands the end of the sleeve by heating, which facilitates subsequent assembly with other components; the adhesive application process applies sealant to the area of ​​the sleeve to be assembled to ensure the sealing performance after connection; and the assembly process fits the sleeve with other materials for installation.

[0003] Currently, the aforementioned processing of sleeves generally employs a semi-automatic manual operation mode. Each step is completed by operators at independent workstations, and the transfer of sleeves between the heat expansion equipment, adhesive application station, and assembly station relies on manual handling or separate conveyor systems. Due to the high degree of manual intervention, the processing rhythm between each workstation is inconsistent, resulting in uncontrollable dwell and transfer times for the sleeves. During this process, the heat-expanded sleeves are prone to shrinkage due to insufficient time to enter the adhesive application and assembly stages and gradual cooling. Simultaneously, the applied adhesive is susceptible to solvent evaporation or pre-curing due to prolonged exposure, affecting bonding performance. This leads to defects such as poor sealing and loose connections after assembly, ultimately reducing product yield. Utility Model Content

[0004] The purpose of this invention is to provide a thermal expansion adhesive coating assembly equipment that can ensure the processing cycle between each workstation and improve product yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: In a first aspect, this utility model provides a thermal expansion adhesive coating assembly equipment, including a transfer mechanism, a sliding frame, multiple picking mechanisms, and multiple processing mechanisms; The transfer mechanism is connected to the sliding frame and drives the sliding frame to reciprocate between the material picking position and the material dispensing position; Each of the picking mechanisms is sequentially installed on the sliding frame along the sliding direction of the sliding frame, and the picking mechanism is configured to pick up and place the first material; Each of the processing mechanisms is distributed sequentially along a direction parallel to the sliding frame. The distance between two adjacent processing mechanisms is equal to the distance between the material picking position and the material dispensing position. When the sliding frame is in the material dispensing position, each picking mechanism and each processing mechanism are arranged in a one-to-one correspondence along a direction perpendicular to the sliding frame.

[0006] Since the distance between two adjacent processing mechanisms is equal to the distance between the picking position and the unloading position, compared with the existing technology, the transfer mechanism can drive each picking mechanism to simultaneously realize the transfer of multiple first materials between two adjacent processing mechanisms, ensuring the processing cycle between each station, and making the dwell time and transfer time of the first material between stations more controllable, thereby improving product yield.

[0007] In an optional embodiment, the transfer mechanism includes a first bracket and a first driver, the sliding frame is slidably engaged with the first bracket, the first driver is mounted on the first bracket, the first driver is connected to the sliding frame and drives the sliding frame to slide relative to the first bracket.

[0008] The above-described implementation achieves a smooth and precise overall transfer of multiple picking mechanisms by forming a sliding guide structure with the sliding frame and the first support, and by providing controllable driving force with the first driver. This ensures efficient connection and high-yield production between processes during continuous operation of the thermal expansion adhesive assembly equipment.

[0009] In an optional embodiment, the picking mechanism includes a second driver and a first clamping assembly. The second driver is mounted on the sliding frame and is connected to the first clamping assembly, which drives the first clamping assembly to move in a direction perpendicular to the movement of the sliding frame. The first clamping assembly is configured to pick up and place a first material.

[0010] The above implementation method can realize the picking and placing of the first material, with multiple picking mechanisms operating synchronously to realize the synchronous picking and placing of multiple first materials, ensuring the processing cycle between each station.

[0011] In an optional embodiment, the plurality of processing mechanisms include a first flaring mechanism, an adhesive application mechanism, and an assembly mechanism; When the sliding frame is in the feeding position, the first flaring mechanism and the glue application mechanism are located vertically below the corresponding picking mechanism, and the assembly mechanism is located horizontally to the side of the corresponding picking mechanism.

[0012] In the above embodiments, when the sliding frame is in the material feeding position, the first flaring mechanism and the glue application mechanism are located vertically below the corresponding picking mechanism, which facilitates the processing of the first material from below. The assembly mechanism is located horizontally to the side of the corresponding picking mechanism to adapt to the requirements of complex assembly paths and the overall compactness of the equipment structure.

[0013] In an optional embodiment, the assembly mechanism includes a second clamping assembly having a second clamping end configured to clamp a second material; When the sliding frame is in the feeding position, the second clamping end is located directly below the corresponding picking mechanism.

[0014] The above-described embodiment achieves efficient and reliable automatic assembly by placing the second clamping end directly below the corresponding picking mechanism and cooperating with the precise docking of the sliding frame at the material feeding position. It is suitable for production scenarios with high requirements for concentricity, assembly force and cycle efficiency.

[0015] In an optional embodiment, the thermal expansion and coating assembly equipment further includes a second bracket and a support base mounted on the second bracket. The support base is provided above both the first flaring mechanism and the coating mechanism. The support base has a receiving channel that passes through the support base and is configured to support the first material.

[0016] The above-described embodiment, by setting a support base with a receiving channel above the first flaring mechanism and the glue coating mechanism, and by using a second bracket to achieve stable installation, effectively positions and provides auxiliary support for the first material in key processing stages, significantly enhancing the stability of equipment operation and the reliability of the process.

[0017] In an optional embodiment, the thermal expansion and coating assembly equipment further includes a second bracket and a third clamping assembly mounted on the second bracket. The third clamping assembly is provided above both the first flaring mechanism and the coating mechanism. The third clamping assembly has a third clamping end configured to clamp the first material.

[0018] The above-described implementation introduces a second bracket as the mounting base for the third clamping assembly, and sets the third clamping assembly above the first flaring mechanism and the gluing mechanism respectively. This not only enhances the reliability of workpiece positioning in key processing steps, but also improves the automation level of the whole machine and the consistency level of the products, meeting the needs of high-cycle, high-precision thermal expansion gluing assembly processes.

[0019] In an optional embodiment, a feeding device and a flipping and conveying device are also included, the feeding device having a channel for conveying the first material, and the flipping and conveying device being configured to clamp and flip the first material at the end of the channel.

[0020] The above-described implementation method achieves automatic conversion of the first material from its original feeding state to a suitable processing posture by setting up a collaborative working mechanism between the feeding device and the flipping and conveying device. This improves the automation level and operational stability of the equipment and effectively ensures the quality consistency and efficiency of subsequent flaring, gluing and assembly processes.

[0021] In an optional embodiment, the feeding device includes an independently operating material blocking mechanism and a material pressing mechanism; The material blocking mechanism has a baffle that moves in a vertical direction, the baffle being configured to block the first material at the end of the material channel and keep the end of the first material protruding out of the material channel; The feed channel has a through groove along a direction perpendicular to its own feeding direction, and the pressing mechanism has a pressure plate that moves in a direction close to or away from the through groove. The pressure plate is configured to press the first material adjacent to the first material at the end into the feed channel.

[0022] The aforementioned feeding device can, on the one hand, precisely limit the position of the first material at the end by using a baffle and expose its end for easy and accurate grabbing in the future; on the other hand, it can actively suppress the upstream material by using a pressure plate to prevent chain slippage and ensure that only a single material is released each time, thereby improving the overall reliability and cycle efficiency of the feeding.

[0023] In an optional embodiment, the flipping and conveying device includes a third driver, a fourth driver, and a fourth clamping assembly. The third driver is connected to the fourth driver and drives the fourth driver to move horizontally. The fourth driver is connected to the fourth clamping assembly and drives the fourth clamping assembly to rotate. The fourth clamping assembly is configured to clamp the first material at the end of the material channel.

[0024] In the above embodiments, the flipping and conveying device provides translational freedom through the third driver, rotational freedom through the fourth driver, and reliable gripping through the fourth clamping component. The three work together to form a multi-degree-of-freedom spatial transport mechanism, which can flexibly adapt to the flipping requirements of first materials of different shapes and sizes.

[0025] In an optional embodiment, a transfer heat expansion device located between the flipping and conveying device and the picking mechanism is also included. The transfer heat expansion device includes a material picking mechanism, a bearing component, a second flaring mechanism, and a transfer mechanism. The material handling mechanism is configured to transfer the first material after it has been flipped by the flipping and conveying device to the bearing component; The second flaring mechanism is located below the supporting component; The transfer mechanism is configured to transfer the first material, after being flared on the carrier component, to a pickup position waiting to be picked up by the pickup mechanism.

[0026] The above implementation method effectively alleviates the pressure on the main production line cycle by introducing a transfer heat expansion device to disperse the heat expansion task, which was originally concentrated in the main processing area, to the upstream area.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] This embodiment provides a thermal expansion adhesive coating assembly device, such as... Figure 1 and Figure 2 As shown, it includes a transfer mechanism 1, a sliding frame 2, multiple picking mechanisms 3, and multiple processing mechanisms; The transfer mechanism 1 is connected to the sliding frame 2 and drives the sliding frame 2 to reciprocate between the material picking position and the material discharging position; Each picking mechanism 3 is installed sequentially on the sliding frame 2 along the sliding direction of the sliding frame 2, and the picking mechanism 3 is configured to pick up and place the first material 7; Each processing mechanism is distributed sequentially along the direction parallel to the sliding frame 2. The distance between two adjacent processing mechanisms is equal to the distance between the material picking position and the material dispensing position. When the sliding frame 2 is in the material dispensing position, each picking mechanism 3 is set up in a one-to-one correspondence with each processing mechanism along the direction perpendicular to the sliding frame 2. When using the thermal expansion adhesive coating assembly equipment provided in this embodiment, such as... Figure 1 As shown, the transfer mechanism 1 drives the sliding frame 2 to move to the material feeding position, the picking mechanism 3 releases the first material 7, and each processing mechanism processes the first material 7; after processing is completed, the transfer mechanism 1 drives the sliding frame 2 to move to the material picking position, and each picking mechanism 3 on the sliding frame 2 picks up the first material 7, and then the transfer mechanism 1 drives the sliding frame 2 to move to the material feeding position, and so on.

[0035] In the above process, since the distance between two adjacent processing mechanisms is equal to the distance between the material picking position and the material dispensing position, the transfer mechanism 1 can drive each picking mechanism 3 to simultaneously realize the transfer of multiple first materials 7 between two adjacent processing mechanisms, ensuring the processing rhythm between each station, and making the dwell time and transfer time of the first material 7 between stations more controllable.

[0036] When the first material 7 is glass, plastic or other materials that are easily scratched or fragile, in order to avoid scratching the first material 7 when the picking mechanism 3 picks up the first material 7, a buffer pad is usually set at the picking end of the picking mechanism 3 to protect the first material 7. However, when the first material 7 is released at the picking end, since the material of the buffer pad is usually rubber, silicone or the like, it is easy to stick to the first material 7, causing the first material 7 to fail to be released in place.

[0037] Therefore, in an optional embodiment, the thermal expansion adhesive assembly equipment further includes a third clamping assembly 10, which is located above at least one processing mechanism and has a third clamping end 101 for clamping the first material 7.

[0038] In the above embodiments, the third clamping end 101 in the third clamping assembly 10 can clamp the first material 7 above the corresponding processing mechanism after the picking mechanism 3 releases the first material 7, so that the first material 7 can stably fall off from the picking mechanism 3, avoiding the first material 7 from being unable to be released into place due to the adhesion between the picking mechanism 3 and the first material 7, and ensuring that the position of the first material is more stable during the processing, thereby improving the product yield.

[0039] In alternative implementations, such as Figure 1 As shown, the transfer mechanism 1 includes a first bracket 11 and a first driver 12. The sliding frame 2 is slidably engaged with the first bracket 11. The first driver 12 is mounted on the first bracket 11. The power output end of the first driver 12 is connected to the sliding frame 2 and drives the sliding frame 2 to slide relative to the first bracket 11.

[0040] The above-described embodiment forms a sliding guide structure with the sliding frame 2 and the first support 11, and provides controllable driving force by the first driver 12, thereby achieving overall stable and precise transfer of multiple picking mechanisms 3, ensuring efficient connection and high yield production between processes in the continuous operation of the thermal expansion adhesive assembly equipment.

[0041] The first support 11 serves as the load-bearing foundation of the entire transfer mechanism 1, possessing sufficient structural strength and rigidity to securely support other related components and provide a stable guiding path for the sliding frame 2. Figure 1 As shown, the first support 11 is plate-shaped and is vertically arranged.

[0042] Specifically, the sliding frame 2 and the first support 11 can achieve a sliding fit through a guide assembly. For example... Figure 1 As shown, the guide assembly includes a slider 21 or a linear bearing disposed on the sliding frame 2, and a guide rail 111 correspondingly mounted on the first bracket 11; or conversely, the guide rail is disposed on the sliding frame 2, and the slider or linear bearing is disposed on the first bracket 11.

[0043] The aforementioned guide components can effectively constrain the sliding frame 2 to reciprocate only along a preset direction (i.e., the direction from the material pick-up position to the material release position), preventing it from deflecting or shaking, thereby ensuring accurate alignment between each picking mechanism 3 and multiple processing mechanisms.

[0044] like Figure 1 As shown, the guide assembly includes a slider 21 disposed on the sliding frame 2 and a guide rail 111 mounted on the first bracket 11. The guide rail 111 can be configured as two parallel rails arranged vertically relative to each other, and each guide rail 111 slides in cooperation with at least one slider 21.

[0045] Additionally, the first driver 12 is mounted on the first bracket 11, specifically by bolt fastening or other detachable connection methods to one end of the first bracket 11. The first driver 12 may include a servo motor or stepper motor in conjunction with a synchronous belt drive mechanism, a ball screw drive mechanism, or a gear and rack drive mechanism; a pneumatic or hydraulic cylinder may also be selected as the power source.

[0046] In alternative implementations, such as Figure 1 As shown, the picking mechanism 3 includes a second driver 31 and a first clamping assembly 32. The second driver 31 is mounted on the sliding frame 2. The power output end of the second driver 31 is connected to the first clamping assembly 32 and drives the first clamping assembly 32 to move in a direction perpendicular to the sliding frame 2. The first clamping assembly 32 is configured to pick up and put down the first material 7.

[0047] In use, the second driver 31 can drive the first clamping assembly 32 to reciprocate between a high position and a low position. When the first clamping assembly 32 descends to the low position, it can contact and clamp the first material 7 located below. When it rises to the high position, it can be transferred to the next processing mechanism for processing under the drive of the transfer mechanism 1. Alternatively, when the first clamping assembly 32 descends to the low position, it can place the first material 7 in place. When it rises to the high position, it can move to the next first material 7 under the drive of the transfer mechanism 1 to clamp the next first material 7.

[0048] The above-described implementation method can realize the picking and placing operation of the first material 7, and the multiple picking mechanisms 3 can operate synchronously to realize the synchronous picking and placing of multiple first materials 7, thus ensuring the processing cycle between each station.

[0049] Specifically, the second actuator 31 can be fixed to the sliding frame 2 by screws or snap-fit ​​structures to ensure its stability and positioning accuracy during synchronous movement with the sliding frame 2. The second actuator 31 can be a cylinder, electric push rod, or servo motor in conjunction with a transmission mechanism and other drive components.

[0050] Alternatively, the first clamping assembly 32 may include a pair of opposing grippers, or adopt a suction cup structure.

[0051] like Figure 2 As shown, the first clamping component 32 may employ two-jaw pneumatic fingers, symmetrical opening and closing clamps, or other clamping mechanisms suitable for the shape of the target product.

[0052] Continue to refer to Figure 2 As shown, the third clamping assembly 10 includes a fifth driver 102 and a third clamping end 101 connected thereto; the fifth driver 102 may be a pneumatic cylinder, an electric linear actuator, etc., for driving the third clamping end 101 to clamp the first material 7; the third clamping end 101 includes two grippers, which open and close under the drive of the fifth driver 102.

[0053] The gripping surface of the gripper is preferably provided with an elastic buffer layer, such as a polyurethane pad, a silicone layer, or a microporous foam material, to reduce the pressure concentration on the surface of the first material 7 and prevent scratches or cracks during the gripping process. It is especially suitable for fragile materials such as glass and plastic.

[0054] In addition, the third clamping component 10 can clamp the first material 7 from the side, and the first clamping component 32 can clamp the first material 7 from above. When the two clamp the first material 7 together, the first clamping component 32 is located above the third clamping component 10 so that the third clamping component 10 and the first clamping component 32 do not interfere with each other. After the third clamping component 10 clamps the first material 7 securely, the first clamping component 32 can release the first material 7.

[0055] In alternative implementations, such as Figure 1 As shown, the multiple processing mechanisms include a first flaring mechanism 4, an adhesive application mechanism 5, and an assembly mechanism 6. When the sliding frame 2 is in the material feeding position, the first flaring mechanism 4 and the adhesive application mechanism 5 are located vertically below the corresponding picking mechanism 3, which facilitates the processing of the first material 7 from below. The assembly mechanism 6 is located horizontally to the side of the corresponding picking mechanism 3 to meet the requirements of complex assembly paths and the overall compactness of the equipment structure.

[0056] The first flaring mechanism 4 is used to flare one end of the first material 7. When the sliding frame 2 moves to the feeding position, the picking mechanism 3 releases the first material 7 directly above the first flaring mechanism 4. Then the first flaring mechanism 4 moves upward and performs the flaring action to complete the pipe opening expansion processing of the first material 7.

[0057] Specifically, the first flaring mechanism 4 includes a sixth driver and a flaring device connected to the sixth driver. The sixth driver is used to drive the flaring device to move in the vertical direction. It can be a pneumatic cylinder, a hydraulic cylinder or a linear motor, etc. The flaring device can be an existing flaring device, and its structure will not be described in detail.

[0058] The adhesive applicator 5 is used to apply a predetermined amount of adhesive to the inner or outer wall of the end of the first material 7 after it has been flared. When the sliding frame 2 is in the feeding position, the adhesive applicator 5 is located directly below another picking mechanism 3. After the picking mechanism 3 releases the first material 7 that has been flared, the adhesive applicator 5 is activated, and its applicator head extends into the flared end of the first material 7 to perform the adhesive applicator operation.

[0059] Specifically, the glue application mechanism 5 includes a seventh driver and a glue application head connected to the seventh driver. The seventh driver is used to drive the glue application head to move in the vertical direction, and it can be a pneumatic cylinder, a hydraulic cylinder or a linear motor, etc.

[0060] The assembly mechanism 6 is used to assemble the first material 7, which has been coated with adhesive, with the second material, for example, by inserting a pipe into a connector or other connecting part. When the sliding frame 2 moves to the material placement position, the picking mechanism 3 moves the first material 7 down, aligns the first material 7 with the installation position of the second material, and assembles the first material 7 with the second material.

[0061] Specifically, such as Figure 1 and Figure 3 As shown, the assembly mechanism 6 includes a second clamping component 61, which has a second clamping end 611 configured to clamp a second material; when the sliding frame 2 is in the feeding position, the second clamping end 611 is located directly below the corresponding picking mechanism 3.

[0062] In use, the second clamping end 611 clamps the second material, and the picking mechanism 3 above the second material drives the first material 7 to move down, aligning the first material 7 with the installation position of the second material.

[0063] The above-described embodiment achieves efficient and reliable automatic assembly by placing the second clamping end 611 directly below the corresponding picking mechanism 3 and cooperating with the precise docking of the sliding frame 2 at the material placement position. It is suitable for production scenarios with high requirements for concentricity, assembly force and cycle efficiency.

[0064] The second clamping component 61 can be a pneumatic finger cylinder, an electric gripper, or a magnetic clamping device, which can clamp the second material at the installation location, thereby ensuring that the installation location does not shift when the first material 7 is aligned with the installation location.

[0065] In alternative implementations, such as Figure 2 As shown, the thermal expansion and coating assembly equipment also includes a second bracket 8 and a support seat 9 installed on the second bracket 8. The support seat 9 is provided above both the first flaring mechanism 4 and the coating mechanism 5. The support seat 9 is provided with a receiving channel 91 that passes through the support seat 9. The receiving channel 91 is configured to support the first material 7.

[0066] During operation, when the sliding frame 2 moves the picking mechanism 3 to the material feeding position, the second driver 31 above the first flaring mechanism 4 and the gluing mechanism 5 drives the first clamping assembly 32 to descend, extending the first material 7 into the receiving channel 91. The support seat 9 provides axial support for the first material 7. After the third clamping assembly 10 clamps the first material 7, the first clamping assembly 32 releases the first material 7. The first flaring mechanism 4 and the gluing mechanism 5 then process the first material 7 above them.

[0067] The above-described embodiment provides a support base 9 with a receiving channel 91 above the first flaring mechanism 4 and the glue coating mechanism 5, and achieves stable installation with the help of the second bracket 8. This enables effective positioning and auxiliary support of the first material 7 in key processing stages, significantly enhancing the stability of equipment operation and process reliability.

[0068] In alternative implementations, such as Figure 1 As shown, the third clamping assembly 10 is installed on the second bracket 8, and the third clamping assembly 10 is provided above both the first flaring mechanism 4 and the glue application mechanism 5.

[0069] When the first flaring mechanism 4 performs the hot flaring operation, on the one hand, the picking mechanism 3 needs to place the first material 7 on the support seat 9, and on the other hand, when the first flaring mechanism 4 extends into the first material 7, the first flaring mechanism 4 will apply an upward pushing force to the first material 7. The third clamping component 10 can provide auxiliary positioning and limiting function by clamping the first material 7. Similarly, when the glue coating mechanism 5 performs circumferential or fixed-point coating operations, the third clamping component 10 can not only ensure that the first material 7 stably leaves the picking mechanism 3, but also ensure the uniformity of the glue path and the accuracy of the position.

[0070] The above-described embodiment introduces a second bracket 8 as the mounting base for the third clamping assembly 10, and sets the third clamping assembly 10 above the first flaring mechanism 4 and the gluing mechanism 5 respectively. This not only enhances the reliability of workpiece positioning in key processing steps, but also improves the automation level of the whole machine and the consistency level of the products, meeting the needs of high-cycle, high-precision hot expansion gluing assembly process.

[0071] In alternative implementations, such as Figure 4 As shown, the thermal expansion adhesive assembly equipment also includes a feeding device 011 and a flipping and transfer device 012. The feeding device 011 and the flipping and transfer device 012 are used to realize the automatic feeding and posture adjustment of the first material 7, so as to adapt to the subsequent stable gripping and continuous processing of the first material 7 by each picking mechanism 3 on the sliding frame 2 driven by the transfer mechanism 1.

[0072] The feeding device 011 is located at the front end of the equipment and is used to continuously supply the first material 7 to the system. Specifically, the feeding device 011 has a material channel 0111 extending in the horizontal direction. The material channel 0111 is configured to accommodate multiple first materials 7 and arrange them in sequence for conveying. The material channel 0111 can take the form of a vibrating feeder, a belt conveyor, or a gravity slide, etc., preferably a vibrating plate combined with a linear feeding track structure, to ensure that the first materials 7 are pushed forward in an orderly manner and accurately positioned at the end of the material channel 0111 for discharge.

[0073] When the first material 7 is a tubular or cylindrical workpiece, its axial direction needs to be horizontal before entering the processing stage, but it needs to be vertical during processing. Therefore, a flipping and transferring device 012 is provided to change the posture of the first material 7. The flipping and transferring device 012 is located near the end of the material channel 0111 and is used to clamp and flip the first material 7 at the end of the material channel 0111 and to horizontally transfer the flipped first material 7 to the next waiting position.

[0074] The above-described implementation method achieves automatic conversion of the first material 7 from its original feeding state to a suitable processing posture by setting up a collaborative working mechanism between the feeding device 011 and the flipping and transferring device 012. This improves the automation level and operational stability of the equipment and effectively ensures the quality consistency and efficiency of subsequent flaring, gluing and assembly processes.

[0075] In alternative implementations, such as Figure 5 and Figure 6 As shown, the feeding device 011 includes an independently operating material blocking mechanism 0112 and a material pressing mechanism 0114, which are used to work together to achieve stable positioning and orderly feeding of the first material 7 at the end of the material channel 0111.

[0076] Among them, such as Figure 5 As shown, the material channel 0111 is horizontally arranged, and the material blocking mechanism 0112 is located near the discharge end of the material channel 0111. It includes a baffle 0113 that can reciprocate vertically. This baffle 0113 is driven by a pneumatic cylinder, an electric linear actuator, or a cam mechanism. When in a descending state, it can block the first material 7 currently at the end from continuing forward; when in an ascending state, it releases the obstruction, allowing the next material to move forward. When the baffle 0113 is in the blocking position, its horizontal position is designed to allow the front end of the first material 7 at the end to protrude from the outlet end of the material channel 0111, forming an exposed section of a preset length. This exposed section facilitates accurate clamping by the subsequent flipping and conveying device 012.

[0077] Among them, such as Figure 6 As shown, the feed channel 0111 has a through groove 0115 on one side wall perpendicular to the feeding direction. This through groove 0115 corresponds to the position of the second-to-last first material 7. The pressing mechanism 0114 is located outside the through groove 0115 and includes a pressing plate 0116 that can move vertically towards / away from the through groove 0115. The pressing plate 0116 is independently driven by a pneumatic cylinder, an electric linear actuator, or a cam mechanism. It can apply pressure to the corresponding first material 7 through the through groove 0115, pressing the first material 7 immediately preceding the end of the first material 7 downwards into the feed channel 0111, preventing it from sliding prematurely to the discharge end due to the pushing force, and facilitating the individual material handling by the flipping and conveying device 012.

[0078] The aforementioned feeding device 011 can, on the one hand, precisely limit the position of the first material 7 at the end through the baffle 0113 and expose its end for easy subsequent precise gripping; on the other hand, it can actively suppress the upstream material through the pressure plate 0116 to prevent chain slippage and ensure that only a single material is released each time, thereby improving the overall reliability and cycle efficiency of the feeding.

[0079] It is worth noting that the blocking mechanism 0112 and the pressing mechanism 0114 adopt independent drive structures, and their operation sequence can be controlled separately. For example, after the blocking mechanism 0112 blocks the first material 7, the pressing mechanism 0114 presses down the second to last first material 7. Then, the blocking mechanism 0112 releases its obstruction of the first material 7, and after the flipping and conveying device 012 takes away the last first material 7, the blocking mechanism 0112 moves to the blocking position and the pressing mechanism 0114 releases the first material 7.

[0080] The aforementioned feeding device, through the independent cooperation of the material blocking and pressing mechanisms, solves the problems of material movement and stacking that easily occur during the feeding of multiple materials, and significantly improves the operational stability and automation level of the thermal expansion adhesive assembly equipment.

[0081] In alternative implementations, such as Figure 7 and Figure 8 As shown, the flipping and transferring device 012 includes a third driver 0121, a fourth driver 0122, and a fourth clamping assembly 0123.

[0082] The third driver 0121 is fixedly installed on the equipment frame, and its power output end is connected to the fourth driver 0122. It is configured to drive the fourth driver 0122 to reciprocate in the horizontal direction, so that the fourth driver 0122 moves closer to or away from the next waiting position. The direction of linear motion is preferably parallel to the feeding direction of the material channel 0111 or perpendicular to the feeding direction of the material channel 0111.

[0083] The third actuator 0121 can be a conventional linear drive mechanism such as a cylinder, electric push rod, or servo motor in conjunction with a lead screw module, which has precise position control capabilities to ensure the accuracy of repeatable positioning.

[0084] The fourth driver 0122 is installed on the moving end of the third driver 0121 and connected to the fourth clamping assembly 0123. It is configured to drive the fourth clamping assembly 0123 to adjust the angle around a rotation axis, preferably to perform a 90° fixed-point rotation action to complete the posture flipping of the first material 7.

[0085] The fourth driver 0122 can be a rotary cylinder, stepper motor or servo motor with reducer and other rotary actuators, and has the characteristics of accurate start and stop and rapid response.

[0086] The fourth clamping assembly 0123 is disposed at the output end of the fourth driver 0122 and is used to clamp the first material 7 located at the end of the feed channel 0111. The fourth clamping assembly 0123 includes a pair of opposing jaws, which realize the opening and closing action through pneumatic, electromagnetic or mechanical elastic structure. The clamping surface can be provided with anti-slip texture or buffer pad layer according to the shape characteristics of the first material 7 to enhance clamping stability and avoid damage to the material surface.

[0087] When the flipping and conveying device 012 is working, the third driver 0121 first drives the entire fourth driver 0122 and the fourth clamping assembly 0123 to move towards the end of the material channel 0111 until the fourth clamping assembly 0123 reaches the clamping position; then the fourth clamping assembly 0123 closes and firmly clamps the first material 7; then the third driver 0121 retracts and pulls the first material 7 out of the material channel 0111; then the fourth driver 0122 starts and drives the clamped first material 7 to complete the rotation of the preset angle; finally, the third driver 0121 accurately transfers the flipped first material 7 to the next waiting position for the picking mechanism 3 on the sliding frame 2 to grab.

[0088] In the above embodiments, the flipping and conveying device 012 provides translational freedom through the third driver 0121, rotational freedom through the fourth driver 0122, and reliable gripping through the fourth clamping component 0123. The three work together to form a multi-degree-of-freedom spatial transport mechanism, which can flexibly adapt to the flipping requirements of the first material 7 of different shapes and sizes.

[0089] To enable the aforementioned flipping and conveying device 012 to adapt to first materials 7 with different axial lengths, it is necessary to ensure that the positioning reference of each first material 7 is consistent when gripping first materials 7 with different axial lengths. For example... Figure 8 As shown, the fourth clamping assembly 0123 is provided with a limiting plate 0124. The limiting plate 0124 is located on the side of the clamping claw in the fourth clamping assembly 0123 away from the material channel 0111. The limiting plate 0124 is used to abut against the first material 7 at the end of the material channel 0111.

[0090] In use, when the fourth driver 0122 drives the fourth clamping assembly 0123 to rotate toward the first material 7 at the end of the material channel 0111, the limiting plate 0124 contacts the end face of the first material 7, the fourth driver 0122 stops operating, and then the fourth clamping assembly 0123 clamps the first material 7.

[0091] The above settings ensure that during the clamping process, the position of the end face of the first material 7 protruding from the material channel 0111 relative to the gripper of the fourth clamping component 0123 remains constant, thus achieving precise positioning with the end face of the first material 7 as a unified reference, and avoiding clamping deviations caused by fluctuations in material size.

[0092] To avoid insufficient heat expansion time and affect the expansion quality and product consistency due to the limited working cycle of the first flaring mechanism 4, in an optional embodiment, the heat expansion and gluing assembly equipment also includes a transfer heat expansion device 013 disposed between the flipping and conveying device 012 and the picking mechanism 3. The transfer heat expansion device 013 is used to complete the preheat expansion treatment before the first material 7 enters each processing mechanism, thereby extending the heat expansion time and improving the overall production efficiency and product quality stability.

[0093] like Figure 5 and Figure 9 As shown, the transfer heat expansion device 013 includes a material handling mechanism 0131, a bearing component 0132, a second flaring mechanism 0133, and a transfer mechanism 0134. These mechanisms work together to form an independent and efficient preheating expansion device, capable of preheating and flaring the first material 7 without affecting the main line's conveying rhythm.

[0094] Specifically, the material handling mechanism 0131 is located near the output end of the flipping and conveying device 012, and can receive the first material 7 that has completed the posture flipping from the flipping and conveying device 012 and transfer it to the carrying component 0132.

[0095] The material handling mechanism 0131 includes a pneumatic cylinder, hydraulic cylinder or linear motor or other linear motion driver that can realize horizontal transfer, as well as a pneumatic gripper or servo-driven manipulator structure connected to the linear motion driver, to realize the transfer of the first material 7 and ensure that the loading and unloading actions are stable and reliable.

[0096] Specifically, the support assembly 0132 includes a positioning seat for supporting and fixing the first material 7. The positioning seat is provided with a limiting cavity adapted to the shape of the first material 7 to prevent it from shifting or tipping over during the heating process.

[0097] The positioning seat can be configured as one or multiple. To increase thermal expansion efficiency, it is preferable to configure multiple positioning seats arranged side by side.

[0098] Specifically, the second flaring mechanism 0133 is located below the supporting component 0132 and can act vertically on the end of the first material 7 to perform local heating and radial expansion operations. The optional structural form of the second flaring mechanism 0133 is similar to that of the first flaring mechanism 4, and will not be described in detail here for the sake of brevity.

[0099] Additionally, the transfer mechanism 0134 is positioned above the carrying assembly 0132 and is configured to transfer the first material 7, after thermal expansion treatment, from the intermediate transfer station to the pickup position where the pickup mechanism 3 awaits pickup. Figure 1As shown, the pickup position can be formed on the placement seat 014 connected to the second bracket 8. The aforementioned transfer mechanism 0134 can be in the form of a linear actuator combined with a clamping mechanism, or it can be a rotary arm structure, depending on the spatial layout and cycle requirements.

[0100] In addition, to ensure that the first material 7 can be stably placed on the supporting component 0132 during the thermal expansion process, such as Figure 9 As shown, the transfer heat expansion device 013 also includes a pressing mechanism 0135, which is located above the supporting component 0132. Since the second flaring mechanism 0133 applies an upward thrust to the first material 7 during heat expansion, the pressing mechanism 0135 can press down on the first material 7 during the heat expansion process to prevent the first material 7 from rising upwards and ensure the heat expansion accuracy and flaring consistency of the first material 7.

[0101] Specifically, the pressing mechanism 0135 may include a driver that moves in a vertical direction and a pressing head connected to the driver. The driver may be a pneumatic cylinder, a hydraulic cylinder or a linear motor, etc., to drive the pressing head to move in a vertical direction, thereby pressing down the first material 7 or releasing the first material 7.

[0102] When the aforementioned transfer and heat expansion device is in use, after the flipping and conveying device 012 has finished flipping the first material 7, the picking mechanism 0131 sequentially loads the first material 7 into multiple parallel positioning seats on the bearing component 0132; then the pressing mechanism 0135 presses down on each of the first materials 7, and the second flaring mechanism 0133 simultaneously performs flaring operations on multiple first materials 7; subsequently, the pressing mechanism 0135 moves upward, and the first materials 7 that have completed flaring are transferred by the transfer mechanism 0134 to the picking position, where the picking mechanism 3 on the sliding frame 2 grabs them when it moves to the picking position. This forms a continuous flow operation, significantly improving the time utilization rate of the heat expansion process.

[0103] The above implementation method, by introducing a transfer heat expansion device 013, disperses the heat expansion task, which was originally concentrated in the main processing area, to the upstream area, effectively alleviating the cycle pressure of the main production line. It is especially suitable for scenarios where the dwell time required for flaring is long, but the cycle time of the entire line is tight.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
