Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a processing table for defective automotive parts. Background Technology

[0002] In the current booming development of new energy vehicles, the charging port end cover, as one of the key components, plays an indispensable role in the quality and performance of the entire vehicle. During the manufacturing process of the charging port end cover, due to the influence of many factors such as the characteristics of raw materials, mold precision, and processing technology, a certain percentage of defective products are inevitably produced.

[0003] Traditionally, the repair of these defective products relies on manual labor. Specifically, workers first need to move the scattered defective products to a designated processing area, then perform sanding and polishing operations one by one. After these preliminary treatments, the products are manually moved to the touch-up painting station for subsequent painting processes. This process has many drawbacks: on the one hand, the frequent manual handling of scattered defective products is labor-intensive and inefficient, and prone to secondary damage due to operational negligence, significantly impacting the overall production cycle; on the other hand, the lack of close coordination between processes and the time-consuming transfer of products between different workstations leads to extended production cycles, making it difficult to meet the ever-increasing production capacity demands.

[0004] With the deepening penetration of the concept of intelligent manufacturing into the manufacturing industry, pallet conveying systems are gradually being introduced to improve the level of production automation and optimize production processes. By placing defective products on pallets and using conveying devices to realize the flow of products between different workstations, there is an urgent need to design a workbench that can both cooperate with pallet conveying and facilitate the grinding and polishing repair of defective products.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a processing table for defective automotive parts, which is designed to facilitate grinding and polishing repair of defective parts in conjunction with pallet transport.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A processing table for defective automotive parts includes a frame, a transfer panel and a base plate mounted on the frame, a tray capable of sliding on the transfer panel, a lifting plate disposed between the transfer panel and the base plate, a pin vertically mounted on the lifting plate, and a linear drive mechanism for driving the lifting plate to move vertically. The transfer panel is located above the base plate. A seat is provided on the tray. The top surface of the seat has a mold cavity corresponding to the shape of the automotive part. The tray has a positioning hole for the pin to be inserted. A shelf is mounted above the transfer panel, and grinding tools and polishing tools are placed on the shelf.

[0009] As a further improvement to the above technical solution, the upper surface of the transmission panel is provided with multiple universal ball bearings.

[0010] As a further improvement to the above technical solution, the two front corners of the transmission panel are provided with guide corner strips for guiding the pallet conveying direction, so as to form an inlet area located between the two guide corner strips, a processing area located behind the inlet area, a waste export area located to the left of the processing area, and a repair export area located to the right of the processing area.

[0011] As a further improvement to the above technical solution, the processing area is provided with multiple pallet pre-positioning structures. Each pallet pre-positioning structure includes a housing, a spring vertically disposed within the housing, and a positioning ball pressing against the top of the spring. A screw for adjusting the spring setting height is provided at the bottom of the housing.

[0012] As a further improvement to the above technical solution, the bottom of the lifting plate is provided with a guide rod, and a sliding sleeve adapted to the guide rod is fixedly provided on the base plate, with the guide rod passing through the sliding sleeve from top to bottom.

[0013] As a further improvement to the above technical solution, the linear drive mechanism includes a cylinder fixed vertically upward on the base plate, and the piston rod end of the cylinder is connected to the lifting plate.

[0014] As a further improvement to the above technical solution, the frame is provided with lifting control buttons for controlling the operation of the linear drive mechanism.

[0015] As a further improvement to the above technical solution, a part-retrieving groove is provided at the edge of the mold cavity. The beneficial effects of this utility model are as follows: Compared with the prior art, the processing table provided by this utility model, through the configuration of a transfer panel, allows workers to simply pull the tray along the transfer panel to the designated processing area. Compared to the traditional manual method of handling defective products one by one, this significantly shortens the workstation changeover time and reduces stalls in the production process. Furthermore, the mold cavity designed on the tray base precisely corresponds to the shape of the automotive parts, providing stable and fitting support for various complex-shaped defective automotive parts, such as automotive charging port end caps. Throughout the entire processing flow, from the placement and transfer of defective products to the final grinding and polishing, the parts remain in an ideal fixed state, effectively avoiding processing errors caused by positional shifts, ensuring reliable product quality after repair, meeting production standards, and greatly improving the finished product qualification rate of reprocessed defective products. Finally, grinding and polishing tools are pre-placed on the shelves, allowing workers to easily access them without searching or frequently changing tool storage locations during defective product repair operations.

Detailed Implementation

[0020] This utility model provides a processing table for defective automotive parts. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figures 1 to 3 This utility model provides a processing table for defective automotive parts, including a frame 1, a transfer panel 21 and a base plate 3 mounted on the frame 1, a tray 41 that can slide on the transfer panel 21, a lifting plate 51 mounted between the transfer panel 21 and the base plate 3, a pin 52 vertically mounted on the lifting plate 51, and a linear drive mechanism 53 for driving the lifting plate 51 to move vertically. The transfer panel 21 is located above the base plate 3. The tray 41 is provided with a seat 42. The top surface of the seat 42 is provided with a mold cavity 43 corresponding to the shape of the automotive parts. The tray 41 is provided with a positioning hole 45 for the pin 52 to be inserted. A shelf 61 is mounted above the transfer panel 21. A grinding tool 62 and a polishing tool 63 are placed on the shelf 61.

[0022] Once a finished automotive part is deemed defective, it is placed within the mold cavity 43 of the seat 42 of the tray 41. Because the mold cavity 43 corresponds to the shape of the automotive part, it ensures the defective part remains stable during subsequent processing. For example, for irregularly shaped parts such as automotive charging port end caps, the mold cavity 43 can tightly conform to their contours, preventing them from wobbling. An external conveying device (such as one working in conjunction with the tray 41 conveying system) can be used to transport the tray 41 containing the defective parts to the processing table. The conveyor panel 21 serves as the carrier for moving the tray 41, allowing workers to pull the tray 41 and slide it across its surface to the processing area 242. Subsequently, the linear drive mechanism 53 is activated. The linear drive mechanism 53 drives the lifting plate 51 to move vertically, causing the vertically positioned pins 52 on the lifting plate 51 to rise accordingly. Because the tray 41 has positioning holes 45 for the insertion of the pin 52, once the pin 52 is inserted into the positioning holes 45, the tray 41 can be precisely positioned in the required processing position, preventing the tray 41 from shifting during subsequent grinding and polishing operations. Since grinding tools 62 and polishing tools 63 are pre-placed on the shelf 61, workers can easily retrieve these tools from the shelf 61 to grind and polish the positioned defective products, completing the repair of surface defects in the automotive parts.

[0023] By utilizing an external conveyor system in conjunction with the processing table transfer panel 21, the defective product tray 41 is rapidly and automatically transferred from the judgment area to the processing area 242. Workers simply need to pull the tray 41 along the transfer panel 21 to the designated processing area 242. Compared to the traditional manual handling of defective products one by one, this significantly reduces workstation changeover time and minimizes production delays. Simultaneously, the precise pin positioning design further optimizes the processing preparation stage, making the entire repair process compact and efficient. This allows for the processing of more defective products per unit time, significantly improving the overall output capacity of the production line and meeting the company's growing production capacity demands. Furthermore, the mold cavity 43 on the tray 41's base 42, precisely corresponding to the shape of the automotive parts, provides stable and snug support for various complex-shaped defective automotive parts, such as automotive charging port end caps. Throughout the entire processing flow, from the placement and transfer of defective products to the final grinding and polishing, the parts are always kept in an ideal fixed state, effectively avoiding processing errors caused by positional deviations, ensuring that the quality of the repaired products is reliable and meets production standards, and greatly improving the finished product qualification rate of reprocessed defective products.

[0024] Furthermore, the upper surface of the transfer panel 21 is provided with a plurality of universal ball bearings 22. These ball bearings 22 are evenly distributed on the upper surface of the transfer panel 21, creating rolling friction with the bottom of the pallet 41. Compared to traditional sliding friction, this rolling friction reduces friction exponentially. When the pallet 41 containing defective automotive parts needs to be moved to the processing area 242, the worker only needs to apply minimal force to make the pallet 41 slide smoothly on the transfer panel 21, greatly reducing the labor intensity of manual operation and improving work efficiency. For example, when handling heavier defective automotive engine block parts, thanks to the low-friction characteristics of the universal ball bearings 22, a single worker can easily push the pallet 41 without the need for multiple people to work together.

[0025] Furthermore, the two front corners of the transfer panel 21 are provided with guide corner strips 23 to guide the conveying direction of the pallet 41, forming an inlet area 241 between the two guide corner strips 23, a processing area 242 behind the inlet area 241, a waste product outlet area 243 to the left of the processing area 242, and a repair outlet area 244 to the right of the processing area 242. The inlet area 241 formed by the guide corner strips 23 provides a clear and precise path guide for the pallet 41 to enter the processing table. When the pallet 41 approaches the processing table with the help of an external conveying device or by manual pushing, the guide corner strips 23 can quickly guide the pallet 41 to slide into the predetermined inlet area 241, avoiding directional deviation of the pallet 41 on the transfer panel 21 or mistakenly entering other areas, reducing the time and manpower required to adjust the position of the pallet 41, and enabling the pallet 41 to enter the processing flow quickly and smoothly, greatly improving the flow efficiency of defective products between workstations.

[0026] The clearly defined processing area 242, waste removal area 243, and repair removal area 244 make the functional layout of the entire processing station readily apparent. Without complex judgments, staff can easily move the pallet 41 to the appropriate area based on its location and subsequent processing results, greatly simplifying the operation process, achieving seamless integration of different processing stages, and further optimizing the overall rhythm of the production line.

[0027] Furthermore, the processing area 242 is provided with multiple tray 41 pre-positioning structures. Each tray 41 pre-positioning structure includes a housing 71, a spring 72 vertically disposed inside the housing 71, and a positioning ball 73 pressing against the top of the spring 72. The bottom of the housing 71 is provided with a screw 74 for adjusting the height of the spring 72.

[0028] Once the pallet 41 enters the processing area 242, the bottom of the pallet 41 interacts with its pre-positioning structure. Multiple positioning balls 73, supported by springs 72, press tightly against the bottom of the pallet 41, constraining it from multiple points and effectively limiting minute horizontal displacement. This ensures the pallet 41 is in an extremely precise initial position before processing. This provides a stable foundation for the subsequent engagement of the pin 52 with the positioning holes 45 on the pallet 41, preventing positioning failure.

[0029] The grinding tool 62 can specifically be sandpaper, a grinding wheel, an electric grinding head, a file, etc., while the polishing tool 63 can be an electric polishing machine or an ultrasonic polishing machine, etc.

[0030] Understandably, the screw 74 located at the bottom of the housing 71 provides a convenient means of adjusting the height of the spring 72. The weight and structure of the tray 41 used for defective automotive parts of different models and specifications may vary. By rotating the screw 74 to change the setting height of the spring 72, and thus adjusting the extension height of the positioning ball 73, the pre-positioning structure of the tray 41 can easily adapt to the needs of various trays 41. Whether it is a lightweight tray 41 supporting small automotive interior parts or a heavy-duty tray 41 used for large automotive engine components, accurate and suitable pre-positioning can be achieved in the processing area 242, enhancing the versatility and adaptability of the processing table.

[0031] Furthermore, the bottom of the lifting plate 51 is provided with a guide rod 54, and a sliding sleeve 55 adapted to the guide rod 54 is fixedly installed on the base plate 3. The guide rod 54 passes through the sliding sleeve 55 from top to bottom. The cooperation between the guide rod 54 and the sliding sleeve 55 provides precise guidance for the vertical movement of the lifting plate 51. When the linear drive mechanism 53 drives the lifting plate 51 to move up and down, the guide rod 54 slides along the inner wall of the sliding sleeve 55, which can strictly limit the horizontal displacement of the lifting plate 51, so that it can only make stable linear movements in the vertical direction. For example, when performing fine operations such as grinding and polishing on defective automotive parts, the tray 41 needs to be precisely positioned and kept stable. This precise lifting movement ensures that the pin 52 can be accurately inserted into the positioning hole 45 of the tray 41, avoiding misalignment of the pin 52 and the positioning hole 45 due to the positional deviation of the lifting plate 51, thereby affecting the accuracy and smoothness of the entire processing flow.

[0032] Preferably, the tray 41 is provided with a handle 46. By applying force with the hand, the tray 41 can be easily pulled or pushed. Compared with the force applied by the seat 42 on the tray 41, the handle 46 provides a more stable point of force, allowing the worker to quickly and accurately control the movement of the tray 41 on the transfer panel 21.

[0033] In this embodiment, the linear drive mechanism 53 includes a cylinder fixed vertically upward on the base plate 3, and the piston rod end of the cylinder is connected to the lifting plate 51. During the operation of the automotive parts defective product processing table, when it is necessary to drive the lifting plate 51 to move vertically, the cylinder can generate sufficient force by its internal gas pressure to overcome the weight of the lifting plate 51 and its components (such as the pin 52) and the resistance of possible friction, ensuring that the lifting plate 51 can smoothly and steadily achieve the rising or falling action, and ensuring the smooth progress of subsequent processing operations such as the accurate insertion of the pin 52 into the positioning hole 45 of the tray 41.

[0034] The frame 1 is equipped with a lifting control button 81 for controlling the operation of the linear drive mechanism 53 and a forced stop lifting button 82. Pressing the lifting control button 81 directly on the frame 1 quickly starts or stops the linear drive mechanism 53, enabling the lifting of the lifting plate 51. If a positioning deviation of the pallet 41 is detected, the worker can immediately press the forced stop lifting button 82 to correct the position of the pallet 41, ensuring smooth processing, greatly shortening emergency response time, reducing production stoppages due to unforeseen circumstances, and guaranteeing the continuous and stable operation of the production line.

[0035] Preferably, the edge of the mold cavity 43 is provided with a part-removing groove 44. The part-removing groove 44 provides a convenient point of leverage for workers. Workers only need to put their fingers or special part-removing tools into the groove and apply light force to remove the parts smoothly, which greatly shortens the time for picking up and putting down a single part. Especially when processing defective automotive parts in batches, it can significantly improve the overall production efficiency.
