Therefore, aluminum alloy materials are widely used in industrial fields such as automobiles and construction. Among aluminum products, cast aluminum products are the most common, that is, aluminum is melted into aluminum liquid at high temperature, and then poured or injected into the molding cavity, and then solidified after cooling. Aluminum products obtained by casting have large internal stress and loose structure. They do not meet the requirements in terms of strength and density, so they need to undergo various heat treatments, such as solid solution and aging treatment.

[0003] A solution aging production line is usually used to carry out solution and aging treatment on automotive aluminum alloy workpieces, such as a fully automatic elevated solution furnace roller aging furnace production line disclosed in Chinese patent announcement number CN219079592U. The solution aging production line of the prior art usually has a circulating conveyor line, which is used to convey the material frame with the workpiece placed on it, and a manipulator is set on one side of the loading area, and the carrier is transferred and unloaded by the manipulator. The workpiece needs to be placed in the material frame in advance, and then the material frame is placed on the carrier. Usually, a carrier will be placed in two layers, with six material frames on each layer. Due to the non-standard placement of the workpiece and the material frame, the material frame is prone to tilt. If the wrongly placed carrier is directly loaded onto the circulating conveyor line, the workpiece is prone to fall during the subsequent transportation process.

DETAILED DESCRIPTION

[0018] The utility model provides a heat treatment device with error-proofing function. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 to Figure 2The present embodiment discloses a heat treatment device with an error-proofing function, including a solution furnace 10 and an aging furnace 20. A loading area is provided on one side of the feeding end of the solution furnace 10, and a feeding module 30 and a limiting module 40 are provided in the loading area. The feeding module 30 includes a first driving device 31 driven along the x-direction, a carrier frame 32 connected to the output end of the first driving device 31, and a first conveying roller 33 provided at the top of the carrier frame 32 and conveying along the x-direction. The first conveying roller 33 conveys a carrier 50, and a workpiece is placed on the carrier 50. A first sensor 61 for sensing the carrier 50 is provided on the carrier frame 32, and a side frame 62 is also provided on the carrier frame 32. A second sensor 63 for sensing the workpiece is provided on the side frame 62. The limiting module 40 includes two columns 41 provided on both sides of the first driving device 31 along the y-direction, and a limiting beam 42 fixed between the two columns 41. The limiting beam 42 is used to limit the height of the workpiece.

[0021] The heat treatment device of this embodiment is provided with a loading area on one side of the feed end of the solid solution furnace 10, and the loading area is provided with a feeding module 30. The workpiece is pre-placed in a material frame, and then the material frame is placed on a carrier 50. The carrier 50 is transferred to the first conveying roller 33 by a robot, and the carrier 32 is driven to the feed end of the solid solution furnace 10 by the first driving device 31. The first conveying roller 33 conveys the carrier 50 to the solid solution furnace 10. Since the aging furnace 20 is long, the distance of the loading area along the x-direction is large. By arranging the first driving device 31 to drive the carrier 32 and the first conveying roller 33, the structure can be simplified and the equipment cost can be reduced.

[0022] In addition, a first sensor 61 for sensing the carrier 50 is provided on the carrier 32, and a side frame 62 is also provided on the carrier 32. A second sensor 63 for sensing the workpiece is provided on the side frame 62. When the carrier 50 loaded with the workpiece is placed on the first conveying roller 33, the first sensor 61 senses the carrier 50, and the first conveying roller 33 starts to convey the carrier 50 for a short distance. If the second sensor 63 senses the workpiece, the carrier 32 is conveyed along the x-direction to the feeding end side of the solid solution furnace 10 through the first driving device 31 to realize automatic conveying. A limiting module 40 is provided in the loading area. The limiting module 40 includes two columns 41 and a limiting beam 42. The limiting beam 42 is used to limit the height of the workpiece. Through the physical limiting effect, it is possible to prevent the wrongly placed workpiece from entering the solid solution furnace 10, causing the subsequent workpiece to fall.

[0023] Furthermore, a pressure sensor and an alarm may be provided on the limit beam 42. When the workpiece touches the pressure sensor, the error prevention system is triggered, that is, the pressure sensor feeds back the signal to the control system, and the control system controls the alarm to start, thereby alerting the staff.

[0024] At the same time, the second sensor 63 is also used to sense whether there is a workpiece in the carrier 50. When the first sensor 61 senses the carrier 50, but the second sensor 63 does not sense the carrier 50, it means that the carrier 50 is unloaded. At this time, the error prevention system is triggered, that is, the first sensor 61 and the second sensor 63 feed back signals to the control system, and the control system controls the alarm to start, thereby reminding the staff.

[0025] Furthermore, the first sensor 61 is a non-contact sensor, such as an infrared sensor, and the sensing end of the first sensor 61 is horizontally toward the carrier 50; the second sensor 63 is a contact sensor, and the second sensor 63 has a downward elastic contact piece 631, and the elastic contact piece 631 is located above the carrier 50. The height of the elastic contact piece 631 can be adjusted according to the actual detection height to adapt to different production needs. If the height of the workpiece loaded on the carrier 50 is lower than the height of the elastic contact piece 631, the workpiece cannot touch the elastic contact piece 63 during transportation, indicating that the carrier 50 is empty or not fully loaded, thereby realizing automatic detection with high detection accuracy.

[0026] like Figure 1 As shown, a second driving device 70 for driving the first conveying roller 33 is provided on one side of the carrier frame 32. The second driving device 70 includes a first motor, a driving wheel 71, a driven wheel 72 and a belt 73. The first motor is fixed on the carrier frame 32. The driving wheel 71 is connected to the output shaft of the first motor. The driven wheel 72 is connected to the end of the first conveying roller 33. The belt 73 is driven by the driving wheel 71 and the driven wheel 72. After the first motor is started, it drives the driving wheel 71 to rotate. Under the action of the belt 73, the driven wheel 72 and the first conveying roller 33 are driven to rotate. The rotation of the first conveying roller 33 realizes the conveying of the carrier 50.

[0027] Further, such as Figure 2 As shown, the installation height of the limiting beam 42 on the two columns 41 is adjustable, and the installation height of the limiting beam 42 is adjusted according to actual production needs. Specifically, a plurality of positioning holes arranged along the z direction can be set on the two columns 41, and the positioning holes at corresponding positions are passed through locking parts such as bolts, and then the limiting beam 42 is fixed, which reduces the difficulty of adjustment.

[0028] In addition, the solid solution furnace 10 is provided with a first feed port 11 and a first discharge port, and the first feed port 11 is arranged toward the side of the loading area, and the aging furnace 20 is provided with a second feed port and a second discharge port 21. The first feed port 11, the second feed port, the first discharge port and the second discharge port 21 are all provided with a door panel assembly 80, and the door panel assembly 80 includes a lifting device 81 and a baffle 82 connected to the output end of the lifting device 81. The solid solution furnace 10 and the aging furnace 20 need to be set to a higher temperature. When feeding or discharging is required, the lifting device 81 can be used to control the baffle 82 to move upward, so that the first inlet, the second inlet, the first outlet and the second outlet are opened, and the carrier can pass smoothly. When feeding or discharging is not required, the lifting device 81 is used to control the baffle 82 to move downward, and the baffle 82 is used to block the first inlet, the second inlet, the first outlet and the second outlet to prevent heat loss.

[0029] A steering conveying module 90 is provided on both the first feed port 11 side and the second feed port side. The steering conveying module 90 includes a bracket 91, two rotating conveying devices 92 provided on the bracket 91, and a plurality of second conveying rollers 93 arranged along the y direction and located between the two rotating conveying devices 92. By providing a steerable rotating conveying device 92, the steering conveying of the carrier 50 is achieved.

[0030] Furthermore, the rotating conveying device 92 includes a second motor fixed on the bracket 91, a circular frame 921 transmission-connected to the output end of the second motor, and a plurality of third conveying rollers 922 arranged in the circular frame 921. The circular frame 921 is rotated by the second motor to adjust the conveying direction of the third conveying rollers 922, thereby realizing the steering conveying of the carrier 50. The end of the third conveying roller 922 can be driven by a motor or a motor gear set.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
