Description

Technical Field

[0001] This invention relates to the field of automotive parts processing equipment technology, specifically to an automatic pressing device for automotive exterior rearview mirror lenses. Background Technology

[0002] As a critical safety component in the driving process, the assembly precision of the lens and the base of the automotive exterior rearview mirror directly affects the driver's visibility and driving safety. The automatic lens pressing equipment for automotive exterior rearview mirrors is one of the core assembly equipment on the automotive parts production line. It is mainly used to accurately and stably press the rearview mirror lens onto the corresponding station of the base, realizing the mechanical snap-fit ​​or adhesive fixation between the lens and the base. It is a key piece of equipment to ensure the consistency of exterior rearview mirror assembly and production efficiency, and is widely used in the large-scale production scenarios of various types of automobiles, including passenger cars and commercial vehicles.

[0003] Early rearview mirror lens assembly mostly relied on manual pressing. Operators would hold a pressing tool, align the lens with the mirror base, and apply force to press it together. This method not only depended on the operator's experience and judgment, resulting in low assembly efficiency and high labor intensity, but also caused quality defects such as lens chipping, mirror base deformation, or weak adhesion due to uneven pressing force and positioning deviation. It was difficult to meet the precision and efficiency requirements of large-scale production in the automotive industry. To solve these problems, automated pressing equipment has gradually emerged in existing technologies. By setting up electric telescopic rods and cylinder drive components to replace manual driving, and with mold blocks and positioning structures, it can achieve precise positioning of the lens and mirror base, effectively improving assembly efficiency and pressing consistency, and avoiding human error caused by manual operation.

[0004] However, the feeding mechanisms of existing automated crimping equipment mostly adopt linear pushing or simple rotary structures. Although they can achieve basic conveying of parts to be crimped, in actual operation, their conveying trajectory is fixed and lacks adaptive adjustment capabilities. When there are slight dimensional tolerances in the lens mounts or lenses to be crimped, positioning offsets will occur. At the same time, the mold bearing structures of existing feeding mechanisms are mostly rigid connections, which are difficult to buffer the impact of vibration during the conveying process, leading to lens displacement. In addition, the feeding and unloading actions of some feeding mechanisms are not seamless, requiring manual assistance to adjust the placement posture of the parts to be crimped, which cannot fully realize continuous and unmanned operation and restricts the improvement of the overall production line utilization rate. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic pressing device for automotive exterior rearview mirror lenses. This device solves the problems of poor positioning adaptability, lens displacement, and the need for manual assistance caused by the fixed structure, rigid load-bearing, and discontinuous feeding and discharging connection of the feeding mechanism in automated pressing equipment, which restrict the utilization rate of the production line.

A proximity sensor is fixedly connected to the front side of the bracket.

[0009] Preferably, the disassembly and replacement mechanism includes a T-shaped groove, which is formed on the outer side of the clamping strip.

[0016] This invention provides an automatic pressing device for automotive exterior rearview mirror lenses. It has the following advantages: 1. This invention uses an electric telescopic rod to push a push plate, causing the rotating bar to tilt forward. The rearview mirror base and lens to be pressed are placed into the mold block station. Then, the electric telescopic rod is controlled to retract, causing the push plate to move backward. The limiting post on the push plate slides within the limiting hole of the rotating bar to match its circumferential motion trajectory. When the electric telescopic rod retracts to the predetermined position, the mold block carries the part to be pressed to the pressing area, and the bottom is positioned against the L-shaped pad, waiting for pressing. After pressing is completed, the electric telescopic rod is activated again to push the push plate. The rotating bar moves the product to the front side through circumferential motion, which is convenient for picking up and loading. The non-rigid connection between the rotating bar and the push plate buffers vibration and prevents lens displacement, realizing a continuous cycle of feeding and unloading without the need for manual adjustment of the posture.

[0017] 2. This invention uses a proximity sensor on the bracket to sense the component to be pressed and send a signal. The control system then activates the push cylinder, whose telescopic end drives the slide rod to slide within the hollow plate, driving the connector and pressure plate to rotate around the bracket to a horizontal position. The push cylinder then stops and locks. Next, the electric push rod starts, pushing the pressure head downward to press the lens against the rearview mirror base. After holding for a set time, the electric push rod retracts, resetting the pressure head. The push cylinder then reverses direction, causing the slide rod to fall, allowing the pressure plate and components to rotate and lift, reserving space for product removal. With the help of the push cylinder locking and the electric push rod precise drive, the pressing process is stable and controllable, avoiding product defects.

[0018] 3. This invention uses the locking bolt on the clamping bar to move the locking plate upward, disengaging it from the locking recess of the mold block and the limiting hole of the clamping bar. Then, the rotating block is rotated to make the locking bolt deviate from the top of the T-slot, allowing the T-strips on both sides of the mold block to be pulled out, thus completing the disassembly of the old mold block. Next, the T-strips adapted to the new specification mold block are inserted into the T-slot, the rotating block is rotated in the opposite direction, and the locking bolt is tightened, so that the locking plate passes through the limiting hole and is locked into the locking recess, thus completing the fixing and replacement of the new mold block. Therefore, different specifications of molds can be disassembled and assembled without complicated tools. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 4and attached Figure 5 This invention provides an automatic pressing device for automotive exterior rearview mirror lenses, including a base 1 and a mold block 6. A fixing column 5 is fixedly connected to the top of the base 1, and a feeding mechanism 2 is provided on the outside of the fixing column 5. The feeding mechanism 2 is used to send the workpiece to be processed to the pressing mechanism. An automatic pressing mechanism 3 is fixedly connected to the outer wall of the fixing column 5. The automatic pressing mechanism 3 is used for pressing the lens. A disassembly and replacement mechanism 4 is provided on the outside of the mold block 6. The disassembly and replacement mechanism 4 is used to replace the molds of different specifications of rearview mirrors. The feeding mechanism 2 includes an electric telescopic rod 21, which is fixedly connected to the front side of the fixed column 5. The telescopic end of the electric telescopic rod 21 is fixedly connected to a push plate 22. The top two sides of the base 1 are fixedly connected to limiting strips 23. Two rotating strips 24 are rotatably connected to the outer side of the limiting strips 23. The inner walls of the push plate 22 are fixedly connected to limiting columns 25. Limiting holes 26 are opened on the outer side of the rear rotating strips 24. The limiting columns 25 are slidably connected to the limiting holes 26. A clamping strip 27 is provided on the top of the limiting strips 23. The end of the rotating strip 24 away from the limiting strips 23 is rotatably connected to the clamping strip 27. The mold block 6 is clamped between the two sets of clamping strips 27. An L-shaped pad 28 is fixedly connected to the top of the base 1. There are two sets of rotating strips 24, which are symmetrically distributed on both sides of the limiting strip 23. The inner side of the clamping strip 27 is provided with a fitting surface that matches the contour of the mold block 6. The outer side of the limiting post 25 is provided with an anti-wear sleeve, which slides and fits against the inner wall of the limiting hole 26. Specifically, in the initial state, the rotating bar 24 drives the mold block 6 to extend forward. At this time, the electric telescopic rod 21 pushes the push plate 22, tilting the rotating bar 24 forward. The exterior rearview mirror and lens to be pressed are then placed in the mold block 6. Subsequently, the electric telescopic rod 21 is activated to retract, driving the push plate 22 to move backward. During this process, since the push plate 22 moves horizontally, the rotating bar 24, driven by the push plate 22, performs a circular motion. This causes the limiting post 25 in the push plate 22 to move within the limiting hole 26 above the rotating bar 24, adapting to the rotation of the rotating bar 24 and the push plate. The positional change between 22: When the electric telescopic rod 21 drives the push plate 22 to retract to the predetermined position, the mold block 6 will move with the required external rearview mirror to the bottom of the pressing mechanism. At the same time, the bottom of the mold block 6 will fall on the L-shaped pad 28 to provide support and limit the mold block 6, preventing displacement during pressing. After pressing is completed, the electric telescopic rod 21 is activated again to push the push plate 22, moving the pressed external rearview mirror to the front in a circular motion, so as to remove the completed external rearview mirror and put in the next external rearview mirror to be pressed, so as to carry out continuous operation.

[0023] See appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 The automatic pressing mechanism 3 includes a push cylinder 31, which is fixedly connected to the outside of the base 1. A bracket 32 ​​is fixedly connected to the top of the fixed column 5. A connector 34 is rotatably connected to the outer wall of the bracket 32. A hollow plate 33 is fixedly connected to the outside of the connector 34. A slide rod is fixedly connected to the telescopic end of the push cylinder 31. The inner side of the hollow plate 33 is slidably connected to the slide rod. A pressure plate 35 is fixedly connected to the top of the connector 34. An electric push rod 36 is fixedly connected to the outside of the pressure plate 35. The telescopic end of the electric push rod 36 passes through the outside of the pressure plate 35 and is fixedly connected to a pressing head 37. The pressing head 37 is located directly above the mold block 6. A proximity sensor 38 is fixedly connected to the front side of the bracket 32. A bearing is provided at the rotatable connection between the connector 34 and the bracket 32. The inner ring of the bearing is fixed to the outer wall of the bracket 32, and the outer ring of the bearing is fixed to the inner wall of the connector 34. The bottom of the pressure head 37 is provided with a mating surface that matches the lens contour, and the edge of the mating surface is provided with a chamfered structure. Specifically, when the feeding mechanism 2 delivers the exterior rearview mirror to be pressed into the pressing area, the proximity sensor 38 senses that the exterior rearview mirror has reached the predetermined position. Then, through the control system, the push cylinder 31 is activated, causing it to extend and push the upper sliding rod upwards. The sliding rod slides within the hollow plate 33, causing the hollow plate 33 to rotate upwards, thereby rotating the connecting piece 34 and the pressing plate 35 together. This continues until the push cylinder 31 reaches its highest point, at which point the pressing... When plate 35 is in a horizontal position, cylinder 31 is stopped, locking the entire connecting piece 34 and pressure plate 35. Then, electric push rod 36 is activated, pushing pressure head 37 downward to press the lens with the exterior rearview mirror. After pressing for a period of time, electric push rod 36 retracts and drives pressure head 37 to move upward and reset. Then, cylinder 31 is restarted, driving slide rod down, which in turn causes the entire pressing mechanism to rotate and lift, so that the pressed exterior rearview mirror can be removed later.

[0024] See appendix Figure 6 Appendix Figure 7 and attached Figure 8 The disassembly and replacement mechanism 4 includes a T-shaped groove 41, which is opened on the outside of the clamping strip 27. A rotating block 42 is rotatably connected to the inside of the T-shaped groove 41. A locking bolt 43 is threadedly connected to the inner wall of the rotating block 42. A locking plate 44 is sleeved on the outside of the locking bolt 43. T-shaped strips 45 are fixedly connected to both sides of the mold block 6. The T-shaped strips 45 abut against the T-shaped groove 41. A locking notch 47 is opened on the top of the mold block 6. A limiting hole 46 is opened on the outside of the clamping strip 27. The locking plate 44 and the limiting hole 46 are inserted and engaged. The bottom of the locking plate 44 is provided with a locking protrusion that matches the locking recess 47, and the top of the locking bolt 43 is provided with a knob; the length of the T-shaped strip 45 is the same as the length of the mold block 6, and the depth of the T-shaped groove 41 matches the thickness of the T-shaped strip 45. Specifically, when it is necessary to press different specifications of exterior rearview mirrors, the locking bolt 43 located above the clamping strip 27 is rotated, so that the locking bolt 43 no longer presses the engaging plate 44 against the limiting hole 46, and the engaging plate 44 is pulled upwards, so that the engaging plate 44 is pulled out of the limiting hole 46. Then, the locking bolt 43 is rotated, so that the rotating block 42 rotates downwards together, so that the locking bolt 43 no longer engages with the engaging notch 47 above the T-shaped strip 45. Then, the mold block 6 is pulled out from the clamping strip 27. During this process, the T-shaped strips 45 on both sides of the mold block 6 are pulled out from the T-shaped grooves 41 in the clamping strip 27. Finally, the mold block 6 is pulled out from the clamping strips 27 on both sides. Finally, the mold block 6 to be replaced is assembled in the original way, so as to complete the quick replacement of molds of different specifications.

[0025] Working principle: First, in the initial state of the equipment, the rotating bar 24, under the pre-tightening force of the mechanical structure, drives the mold block 6 to maintain a forward-extending posture. The electric telescopic rod 21 is activated, and its telescopic end drives the push plate 22 to move forward horizontally. The push plate 22, through the limiting posts 25 fixed on both sides, forms a sliding fit with the limiting holes 26 on the outer side of the rotating bar 24, forcing the rotating bar 24 to tilt forward around the hinge point of the limiting bar 23. At this time, the mold block 6 is in an open position for easy material feeding. The operator places the rearview mirror base and lens to be pressed into the preset positions on the mold block 6. After feeding, the control system issues a command to retract the electric telescopic rod 21 horizontally, driving the push plate 22 to reset to the rear. During this process, the limiting posts 25 slide along the arc trajectory of the limiting holes 26, adapting to the circular motion trajectory of the rotating bar 24 around the limiting bar 23, ensuring that the linear motion of the push plate 22 and the rotational motion of the rotating bar 24 are parallel. With a stable connection, when the electric telescopic rod 21 retracts to the preset end point of the stroke, the mold block 6 carries the part to be pressed and moves precisely to the underside of the pressing area. The bottom of the mold block 6 is completely in contact with the upper surface of the L-shaped pad 28 fixed at the top of the base 1. The L-shaped pad 28 provides vertical support and horizontal limit for the mold block 6, preventing displacement during the pressing process. After pressing, the electric telescopic rod 21 starts again and pushes the push plate 22 forward. The circular motion of the rotating bar 24 drives the mold block 6 back to the front extension position, so that the operator can pick up and put down the finished product and put in the next set of parts to be pressed. Since the rotating bar 24 and the push plate 22 are connected by the limiting column 25 and the limiting hole 26, the vibration generated by the operation of the equipment can be buffered to prevent the lens from shifting during the conveying process. At the same time, the continuous cycle of feeding and discharging actions is realized. There is no need for manual assistance to adjust the posture of the part to be pressed, solving the technical problem of continuous and unmanned operation and significantly improving the utilization rate of the production line. Furthermore, through the automatic pressing mechanism 3, after the feeding mechanism 2 delivers the workpiece to be pressed to the designated pressing position, the proximity sensor 38 fixed to the front side of the bracket 32 ​​senses the workpiece and sends a position signal to the control system. After receiving the signal, the control system activates the push cylinder 31. The extension end of the push cylinder 31 drives the slide rod to move vertically upward. The slide rod forms a sliding fit with the hollow plate 33 fixed on the outside of the connector 34. Under the thrust of the slide rod, the hollow plate 33 drives the connector 34 to rotate around the hinge point on the outer wall of the bracket 32, thereby driving the pressure plate 35 fixed on the top of the connector 34 to rotate synchronously. When the extension end of the push cylinder 31 extends to its maximum stroke, the pressure plate 35 just rotates to a horizontal state. At this time, the push cylinder 31 stops running and maintains the current state through the air pressure locking function to ensure the stability of the pressure plate 35 and subsequent pressing actions. Subsequently, the control system activates the electric push rod 36 fixed on the outside of the pressure plate 35. The telescopic end of the push rod 36 extends downward in the vertical direction, pushing the pressure head 37, which is fixed at the end, to move towards the part to be pressed, so as to achieve precise pressing of the lens and the outer rearview mirror base. After the pressing action is held for a preset pressure holding time, the telescopic end of the electric push rod 36 retracts, driving the pressure head 37 to return to the initial position. Then, the cylinder 31 is pushed to run in the opposite direction, and the telescopic end of the cylinder 31 drives the slide rod to fall downward in the vertical direction. The hollow plate 33 drives the connector 34, the pressure plate 35 and the electric push rod 36 to rotate and lift in the opposite direction at the same time, leaving enough space for the subsequent removal of the finished product. The locking function of the push cylinder 31 ensures the stability of the pressure plate 35. The electric push rod 36 realizes precise control of the pressing force and the pressing stroke, avoiding product defects caused by uneven pressing force and pressing position deviation. At the same time, after pressing, each component automatically resets and lifts, providing reliable protection for continuous operation and greatly improving the pressing accuracy and production efficiency. Simultaneously, by disassembling and replacing mechanism 4, when it is necessary to adapt to different specifications of exterior rearview mirror products, the operator rotates the locking bolt 43 on the outside of the clamping strip 27. Since the locking bolt 43 and the rotating block 42, which is rotatably connected to the bottom of the inner side of the T-slot 41, form a threaded engagement, the rotation of the locking bolt 43 drives the locking plate 44 to move vertically upward until the locking plate 44 completely disengages from the locking recess 47 on the top of the mold block 6 and the limiting hole 46 on the outside of the clamping strip 27. Then, the rotating block 42 is rotated so that the locking bolt 43 and the locking plate 44 are offset from the top of the T-slot 41, releasing the limiting constraint on the mold block 6. At this time, the mold block 6 can be pulled out horizontally, and the T-strips 45 fixed on both sides of the mold block 6 slide and separate along the T-slots 41 on the outside of the clamping strip 27, completing the disassembly of the old mold block 6. Align the T-shaped strips 45 on both sides of the mold block 6 adapted to the new specification with the T-shaped grooves 41 of the clamping strips 27 and push them in horizontally until the mold block 6 is installed in place. Then, rotate the rotating block 42 in the opposite direction to reset the locking bolts 43 and the locking plate 44 to the top of the T-shaped grooves 41. Tighten the locking bolts 43 to move the locking plate 44 vertically downward until the locking plate 44 passes through the limiting hole 46 and is fully engaged in the locking recess 47 of the mold block 6. Through the matching positioning of the T-shaped strips 45 and the T-shaped grooves 41 and the double fixing of the locking plate 44 and the locking bolts 43, the new mold block 6 is firmly installed. Without the need for complicated tools, the disassembly and assembly of molds of different specifications can be completed quickly, which significantly improves the adaptability of the equipment to multiple models of exterior rearview mirror products, meets diversified production needs, and reduces the cost of model changeover and debugging.
