Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts manufacturing technology, specifically relating to a flexible and rapid changeover production line equipment. Background Technology

[0002] Currently, automotive products are being updated and replaced rapidly, and the corresponding automotive parts also need to be updated and replaced quickly. Production line equipment includes a double-speed chain for conveying parts and multiple processing devices attached to the double-speed chain. Each processing device corresponds to one processing step of the part. Because the double-speed chain and multiple processing devices of the production line equipment are integrated together, it leads to high investment, poor flexibility, and low investment utilization for manufacturing enterprises. When product design and capacity requirements change, it is difficult to adapt the equipment and the equipment development cycle is long. At the same time, in the past, the electrical, pneumatic and network interfaces of the equipment were all directly connected to each workstation by wires, air pipes and network cables from the production line bus, which made the wiring numerous and complex during the modification. Summary of the Invention

[0003] To address the technical challenge of modifying existing production line equipment, this application proposes a flexible and rapid changeover production line device that solves the aforementioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a flexible and rapid changeover production line equipment, comprising: a conveying device, which is fixedly configured; a processing device, which is moved and connected to the conveyor line of the conveying device, including a lower machine platform and an upper frame mounted on the lower machine platform, wherein a portion of the table space of the lower machine platform is formed as an installation space for a robotic arm, and another portion is formed as a conveying space for connecting to the conveying device; a positioning device, which includes a limiting block and a positioning pin fixed on the table surface of the lower machine platform for abutting against the side of the conveying device facing the installation space, and a positioning block fixed on the conveying device and cooperating with the positioning pin, wherein the positioning block has a positioning hole with a wider outer side and a narrower inner side for receiving the positioning pin; and a locking device, which includes a first locking plate fixed on the side of the conveying device facing away from the installation space and extending horizontally, and a second locking plate fixed on the table surface of the lower machine platform and cooperating with the first locking plate, wherein the first locking plate is provided with a locking pin that is simultaneously inserted into the first locking plate and the second locking plate.

[0006] Furthermore, the conveying device includes two parallel double-speed chains, with a clearance space between the double-speed chains and the ground to allow the processing device to enter after translation.

[0007] Furthermore, the lower machine platform is equipped with a two-stage lifting assembly, which includes a first lifting plate and a second lifting plate disposed on the first lifting plate. At the same time, a pallet for placing workpieces is conveyed on the two double-speed chains. After the first lifting plate of the two-stage lifting assembly is lifted, the second lifting plate protrudes from the table surface of the lower machine platform. The second lifting plate rises and lifts the pallet so that the workpiece on the pallet can enter the processing position.

[0008] Furthermore, a primary fixture is provided on the tray, and a secondary fixture is provided on the primary fixture.

[0009] Furthermore, the tray is provided with alignment holes, and correspondingly, the two-section lifting plates are provided with alignment pins that mate with the alignment holes.

[0010] Furthermore, the upper frame is equipped with a flap at the inlet for connecting to the conveying device.

[0011] Furthermore, it also includes a separate main control cabinet, which is equipped with a cable tray that integrates power, air and network interfaces for use by the processing device.

[0012] Furthermore, the top of the lower platform is equipped with casters and adjustable support feet.

[0013] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0014] This utility model discloses a flexible and rapid-change production line equipment. The conveyor device is fixedly configured to match the actual configuration of conveyor devices in the production workshop, such as a 10-meter-long U-shaped conveyor device fixed to the ground. The conveyor device can be equipped with one or more processing devices. After a single processing device is moved horizontally, it can be connected to the conveyor line of the conveyor device. Specifically, by pushing the processing device, the limiting block on the lower platform of the processing device abuts against the side of the conveyor device, thereby determining the relative position of the processing device with respect to the conveyor device in the vertical direction in the horizontal direction. When the positioning pin on the lower platform of the processing device enters the positioning hole with a wider outer width and a narrower inner width on the positioning block of the conveyor device, the relative position of the processing device with respect to the conveyor device in the horizontal direction is further determined. The relative positions of the conveying devices in the parallel direction are used to align the processing device with the conveying device. Then, locking pins are inserted sequentially into the first locking plate of the conveying device and the second locking plate of the processing device to lock the conveying device and the processing device. This allows for quick and easy docking of the processing device onto the conveying device without any modifications. The processing device can be quickly merged or removed from the conveying device without any modifications, enabling rapid switching between the conveying device and a single processing device on the production line without additional modifications. This facilitates rapid access to the processing device, avoids repeated modifications to the production line equipment, reduces repetitive investment, and improves the adaptability of the production line equipment to different products and production lines, thereby increasing the utilization rate of the production line equipment and reducing investment costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] like Figure 1-11As shown, this utility model provides a flexible and rapid changeover production line equipment, including a conveying device 1, a processing device 2, a positioning device, and a locking device. The conveying device 1 is fixedly configured, and the processing device 2 is moved and docked on the conveyor line of the conveying device 1. It includes a lower platform 21 and an upper frame 22 mounted on the lower platform 21. A portion of the platform space of the lower platform 21 forms an installation space 23 for configuring a robotic arm, and another portion forms a conveying space 24 for connecting to the conveying device 1. The positioning device includes a limiting device fixed on the platform of the lower platform 21 to abut against the side of the conveying device 1 facing the installation space 23. Positioning block 25 and positioning pin 26, and positioning block 11 fixed on conveying device 1 and cooperating with positioning pin 26. Positioning block 11 has a positioning hole 12 with a wider outer side and a narrower inner side for receiving positioning pin 26. Positioning hole 12 is preferably a "V" shaped hole. Locking device includes a first locking plate 13 fixed on the side of conveying device 1 facing away from installation space 23 and extending horizontally, and a second locking plate 27 fixed on the table surface of lower platform 21 and cooperating with first locking plate 13. Locking pin 14 is provided on first locking plate 13 and simultaneously inserted into first locking plate 13 and second locking plate 27. Locking pin 14 is preferably a self-locking locking pin with a handle.

[0032] In one specific embodiment of this utility model, the top of the lower platform 21 is provided with rollers 211 and adjustable support feet 212.

[0033] In the flexible and rapid changeover production line equipment of this utility model, the table height of the lower platform 21 of the processing device 2 is set at the beginning and is adjusted by the support legs 212 to cooperate with the conveying device 1.

[0034] In one specific embodiment of this utility model, the conveying device 1 includes two parallel double-speed chains 15, and a clearance space is formed between the double-speed chains 15 and the ground to allow the lower platform 21 of the processing device 2 after translation to enter.

[0035] Meanwhile, a portion of the upper frame 22 of the processing device 2 is opened to form an access point for connecting the speed-multiplying chain 15. Preferably, a flap 221 is provided at the access point, which is aesthetically pleasing and allows the lower machine platform 21 and the upper frame 22 to be connected without separating them.

[0036] In one specific embodiment of this utility model, a two-stage lifting assembly 28 is configured inside the lower machine platform 21. The two-stage lifting assembly 28 includes a first lifting plate 281 and a second lifting plate 282 disposed on the first lifting plate 281. Simultaneously, a workpiece tray 3 is conveyed on two double-speed chains 15. After the first lifting plate 281 of the two-stage lifting assembly 28 is lifted, the second lifting plate 282 protrudes from the table surface of the lower machine platform 21, slightly lower than the tray 3. The second lifting plate 282 rises to lift the tray 3 so that the workpiece on the tray 3 can enter the processing position. When the two-stage lifting assembly 28 descends into the lower machine platform 21, the processing device 2 moves horizontally and connects with the conveyor device 1 to prevent the two-stage lifting assembly 28 from colliding with the conveyor device 1 and causing interference. The significance of setting the first lifting plate 281 and the second lifting plate 282 in the two-stage lifting assembly 28 is that the second lifting plate 282 is dedicated to lifting the tray 3, thereby reducing the lifting stroke for processing a single workpiece during the processing and speeding up the cycle time.

[0037] Specifically, both the first-stage lifting plate 281 and the second-stage lifting plate 282 are driven by cylinders. In order to ensure linear movement in the vertical direction, a guide assembly is configured between the cylinder and the lifting plate, including a guide rod and a guide post sleeved on the guide rod.

[0038] In a preferred embodiment of this invention, a primary fixture 31 is mounted on the tray 3, and a secondary fixture 32 is mounted on the primary fixture 31. The tray 3 is placed directly on the double-speed chain 15 without needing to be replaced. The primary fixture 31 is replaced when changing production between different product categories with significant differences, while the secondary fixture 32 is replaced when changing production between the same product category with minor differences. This fixture classification reduces the scope of tooling changes and decreases investment in new products.

[0039] In a preferred embodiment of the present invention, the tray 3 is provided with an alignment hole 33, and correspondingly, the two-section lifting plate 282 is provided with an alignment pin 2821 that cooperates with the alignment hole 33, so that the tray 3 can be lifted in the accurate position.

[0040] In a preferred embodiment of this utility model, a separate main control cabinet 4 is also included, such as on the wall next to the conveying device 1 or above the conveying device 1. The main control cabinet 4 is equipped with a cable tray 41 that integrates power, gas and network interfaces for use by the processing device 2, which can enable the corresponding processing device 2 to be powered on, supplied with gas and connected to the local area network quickly.

[0041] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
