[0001] The invention relates to the technical field of automobile production, in particular to a layout and system of a semi-automatic production line of a plastic back door. Background Art

[0002] With the promotion and application of new energy vehicles, mileage anxiety is particularly prominent. Lightweighting of vehicles is an important way to increase mileage. Replacing steel with plastic can reduce weight by 10% to 30%. Plastic back doors instead of metal back doors are one of the application scenarios. The inner and outer panels of the plastic back door are bonded by polyurethane glue. The general process of back door gluing: cleaning of inner and outer panels; activation of inner and outer panels; gluing of outer panels; pressing and curing of inner and outer panels; static curing of inner and outer panel gluing assembly. The layout of the plastic back door production line directly affects the function and quantity of production line tooling and equipment, the stability of product quality, the level of production efficiency and manufacturing cost.

[0003] The cleaning, activation, gluing, pressing and standing processes are independent: the process is long, the products are easily contaminated and scratched during manual transportation of logistics at each workstation, the production process is difficult to control, and the quality is unstable. The advantage is that the production is flexible, the production cycle of each workstation is short, and the production line investment is small.

[0004] Cleaning, activation, gluing and pressing are highly integrated in one workstation: short process, less logistics process, product is not easy to be contaminated or scratched, production process is easy to control and quality is stable. The disadvantage is that the process is concentrated and the production cycle is long. If the production capacity requirements of customers are to be met, the production line investment is high.

The working range of the gluing and pressing robot covers the gluing robot and the pressing tooling, but the working range of the gluing and pressing robot does not overlap with the working range of the activation robot. The gluing robot performs gluing operations on the outer panel, and the inner panel and the outer panel are pressed and initially fixed in the pressing tooling; the static area is arranged below the handling robot, and the handling robot grabs the initially fixed back door assembly and places it in the static area.

[0007] In order to better realize the present invention, further, it also includes a ground rail, the pressing tooling is set to be multiple, the multiple pressing tooling is linearly equidistantly arranged, the placement direction of the ground rail is parallel to the arrangement direction of the pressing tooling, the handling robot is installed on the ground rail, the handling robot cooperates with the ground rail so that the working range of the handling robot covers the multiple pressing tools, and the working range of the gluing and pressing robot also covers the multiple pressing tools.

[0008] In order to better realize the present invention, it further includes a static chain, the placement direction of the static chain is arranged parallel to the placement direction of the ground rail, and one end of the static chain is in the static area; when the handling robot grabs the back door assembly in the pressing tooling, it is directly transferred to the static chain in the static area, and is transported out by the static chain.

[0017] Embodiment 1: This embodiment provides a layout of a semi-automatic production line for plastic back doors. Figure 1As shown, it includes an inner plate cleaning and activation tool 1, an outer plate cleaning and activation tool 2, an activation robot 3, a gluing and pressing robot 4, a gluing robot 5, a pressing tool 6, a handling robot 7 and a static area; the inner plate cleaning and activation tool 1 is located on the right side of the activation robot 3, and the outer plate cleaning and activation tool 2 is located above the activation robot 3, and the working range of the activation robot 3 covers the inner plate cleaning and activation tool 1 and the outer plate cleaning and activation tool 2, and the inner plate is placed in the inner plate cleaning and activation tool 1 and the outer plate is placed in the outer plate cleaning and activation tool 2, and they are cleaned and activated by the activation robot 3; the pressing tool 6 is arranged on the left side of the activation robot 3, and the handling robot 7 is arranged below the pressing tool 6 and the activation robot 3, and the working range of the handling robot 7 covers the pressing tool 6, the inner plate cleaning and activation tool 1 and the static area, and after the inner plate is cleaned, it is grabbed by the handling robot 7 and placed in the lower mold of the pressing tool 6 ; After the outer panel is cleaned, it is manually transferred to the upper mold of the pressing tool 6; the glue-coating and pressing robot 4 is arranged above the pressing tool 6, and the glue-coating and pressing robot 5 is arranged on the upper left of the glue-coating and pressing robot 4. The working range of the glue-coating and pressing robot 4 covers the glue-coating and pressing robot 5 and the pressing tool 6, but the working range of the glue-coating and pressing robot 4 does not overlap with the working range of the activation robot 3. The glue-coating and pressing robot 4 grabs the upper mold of the pressing tool 6 and carries the outer panel to the glue-coating and pressing robot 4. At the gluing robot 5, the gluing robot 5 applies glue to the outer panel, and then the gluing and pressing robot 4 presses the upper mold of the outer panel with qualified glue with the lower mold of the pressing tool 6, and the inner panel and the outer panel are pressed and initially fixed in the pressing tool 6; the static area is set below the handling robot 7, and when the initial fixing of the inner panel and the outer panel is completed, the gluing and pressing robot 4 grabs the upper mold of the pressing tool 6 to open the mold, and the handling robot 7 grabs the initially fixed back door assembly and places it in the static area. It should be noted here that the above-mentioned inner panel cleaning and activation tool 1, outer panel cleaning and activation tool 2, activation robot 3, gluing and pressing robot 4, gluing robot 5, pressing tool 6, and handling robot 7 are all purchased products, so their working principles and specific structures are understandable to those skilled in the art.

[0018] During production, the staff transports the inner panel and places it in the inner panel cleaning and activation tooling 1. After manually cleaning the glue line of the inner panel, the activation robot 3 is started, and the activation robot 3 starts to activate the inner panel. After the cleaning and activation of the inner panel is completed, the transport robot 7 is started, and begins to grab the inner panel from the inner panel cleaning and activation tooling 1, and transfers and places it in the lower mold of the pressing tooling 6. This avoids the problem that the inner panel product is easily contaminated by the glue line during the transportation process from the cleaning and activation station to the pressing station, resulting in failure of the product's gluing and pressing, and is easily scratched and damaged, resulting in product scrapping.

[0019] At this time, the staff begins to move the outer panel and place it in the outer panel cleaning and activation tooling 2. After manually cleaning the outer panel glue line, the activation robot 3 is started again, and the activation robot 3 begins to activate the outer panel. After the outer panel cleaning and activation is completed, the cleaned and activated and qualified outer panel is manually taken out from the outer panel cleaning and activation tooling 2, and transferred and placed in the upper mold of the pressing tooling 6.

[0020] Start the glue-coating and pressing robot 4, which grabs the upper mold with the outer panel installed and transfers it to the working range of the glue-coating robot 5. Then start the glue-coating robot 5, which begins to apply glue to the corresponding position of the outer panel and checks whether it is qualified. After the inspection is qualified, the glue-coating and pressing robot 4 continues to carry the upper mold back and presses the upper mold with the lower mold, so that the outer panel and the inner panel are bonded by the applied glue in the pressing tooling 6 for initial consolidation.

[0021] After the outer panel and the inner panel are initially pressed and consolidated in the pressing tool 6, a back door assembly is formed. At this time, the glue coating and pressing robot 4 is started to grab the upper mold of the pressing tool 6 to open the mold to expose the back door assembly, and then the transport robot 7 is started to make the transport robot 7 grab the back door assembly in the lower mold of the pressing tool 6 and transport it to the static area, waiting for the staff to transport it to the next process.

[0022] Through the above-mentioned arrangement, the contamination and scratches of materials caused by manual handling are reduced, the material transfer efficiency and the stability of the gluing and pressing quality in the plastic back door production process are improved, the temporary storage stations on the line side for cleaning and activation of inner and outer panels and the labor for logistics turnover are reduced, the automation degree and production efficiency of the production line are effectively improved, the layout is compact, the logistics are smooth, and it has good practicality.

[0023] Embodiment 2: This embodiment is further expanded on the basis of the above embodiment. Figure 1 As shown, it also includes a ground rail 9, the pressing tool 6 is provided in multiple numbers, the multiple pressing tool 6 is linearly and equidistantly arranged, the placement direction of the ground rail 9 is arranged in parallel with the arrangement direction of the pressing tool 6, the handling robot 7 is installed on the ground rail 9, and the handling robot 7 cooperates with the ground rail 9 so that the working range of the handling robot 7 covers the multiple pressing tool 6, and the working range of the glue pressing robot 4 also covers the multiple pressing tool 6. It should be noted here that the ground rail 9 mentioned above is a purchased product, so its working principle and specific structure are understandable to those skilled in the art.

[0024] When the inner plate and outer plate in a pressing tool 6 are in the initial pressing and consolidation state, the inner plate cleaning and activation tool 1, the outer plate cleaning and activation tool 2, and the activation robot 3 also continue to work. The handling robot 7 grabs another inner plate that has been cleaned and activated, slides on the ground rail 9, and then places it in the lower mold of another pressing tool 6, and the outer plate that has been cleaned and activated is also manually transported and placed in the corresponding upper mold; when the last pressing tool 6 starts to close the mold and press, the initial consolidation of the inner and outer plates in the first pressing tool 6 is completed, so that the connection can be made to achieve continuous production without waiting, thereby greatly improving production efficiency.

[0025] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0026] Embodiment 3: This embodiment is further expanded on the basis of the above embodiment. Figure 1 As shown, it also includes a static chain 8, the placement direction of the static chain 8 is arranged parallel to the placement direction of the ground rail 9, the left end of the static chain 8 is in the static area, which is the static chain upper part area, and the right end is the static chain lower part area; when the handling robot 7 grabs the back door assembly in the pressing tooling 6, it is directly transferred to the static chain upper part area, and the static chain 8 transports it to the right static chain lower part area. The static process does not require manual handling, which reduces the bumps, scratches or debonding of the inner and outer panels of the initially fixed back door assembly during manual handling, resulting in product scrapping. It should be noted here that the static chain 8 mentioned above is a purchased product, so its working principle and specific structure are understandable to those skilled in the art.

It should be noted here that the glue room 10 mentioned above is a purchased product, so its working principle and specific structure are understandable to those skilled in the art.

[0029] When the gluing robot 5 is applying glue, the glue machine in the glue room 10 will continuously extract glue liquid to replenish it into the gluing robot 5, which can quickly replenish the glue liquid; secondly, it will not affect the gluing operation of the outer panel, further improving production efficiency.

[0030] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.
