Description

Technical Field

[0001] The present invention relates to the technical field of refrigerated truck manufacturing, and particularly relates to a production device for the forming and manufacturing of refrigerated trucks. Background Art

[0002] A refrigerated truck is an enclosed van used to transport frozen or fresh goods, and is commonly used to transport frozen foods, dairy products, fruits and vegetables, vaccines, and medicines, etc.

[0003] Currently, when manufacturing refrigerated trucks, since the box panels of the box body are mostly composite materials, and the hardness and elasticity of each layer of material are different, in order to avoid cracking of the materials or compression failure of the insulation layer caused by excessive mechanical pressure, manual splicing and assembly are mostly used, resulting in low production efficiency of refrigerated trucks. At the same time, the box panels of the refrigerated truck body are usually divided into front and back sides. The front side faces outwards and often uses materials with strong weather resistance and corrosion resistance. The back side faces inwards and often uses food-grade or easily cleanable materials. However, the front and back sides of the box panels have little difference in appearance. After being hoisted to the assembly position of the refrigerated truck body, it is necessary to carefully distinguish them before assembly production, which affects the production progress. Therefore, a production device for the forming and manufacturing of refrigerated trucks is proposed. Summary of the Invention

[0011] Preferably, the top of the stacking seat is slidably connected to the positioning concave plate through a guiding column. The positioning concave plates on the three stacking seats are different in size and model, and are used to adapt to different box plates of the refrigerated truck box body.

[0012] Preferably, the suspension conveying guide rail is in a cross - shaped state. The inner side wall of the suspension conveying guide rail is slidably connected to the guiding seat. The guiding seat is rotatably connected to the suspension plate through a rotating shaft. The suspension plate is fixedly connected to a control seat through a lifting suspension rod. The control seat is fixedly connected to a right - angle limiting seat through a steering robotic arm.

[0013] Preferably, the side - pressing component is composed of an adjusting rack and a plurality of side - pressing gears.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the setting of the slow support component and the palletizing board, this solution can adjust the position of the guiding plate to make the slow support air cushion pad dynamically adapt to box boards of different sizes, evenly disperse the pressure, avoid the compression deformation of the thermal insulation layer of the lower box board during stacked storage (especially protect the structural integrity of the polyurethane foam layer), and at the same time use the inclined guiding frame and the self-adjusting telescopic rod to smoothly lift the box board, reducing the risk of edge bumps caused by manual handling and protecting the surface coating and sealing structure.

[0019] 2. Through the setting of the palletizing base and the palletizing board, this solution can drive the palletizing board to rotate and switch by using the retaining frame to achieve the classified storage of box boards of multiple specifications, reduce the floor area, and at the same time meet the requirements of "rectification" and "cleaning" in 5S management, improving the space utilization rate of the production area.

[0020] 3. Through the setting of the side pressure component and the magnetic rubber plate, this solution can form a flexible clamping by using magnetic repulsion force, avoid scratches or indentations on the surface of the box board (especially the inner food-grade coating) caused by rigid clamps, reduce the rework rate, and at the same time the hydraulic push rod drives the side pressing plate to tightly press the edge of the box board at multiple angles, dispersing the clamping pressure and preventing delamination of the composite material due to excessive local stress.

[0021] 4. Through the setting of the position detection component, this solution can utilize the difference in roughness between the front and back sides of the box board (the outer surface is rough / the inner surface is smooth), apply the same pressure through the bidirectional electric push rod, detect the difference in friction force and convert it into a conductive liquid displacement signal, automatically judge the front and back directions, and if the detected direction is incorrect, the intelligent suspension conveying system immediately flips the box board to avoid manual inspection errors and ensure the correct installation orientation.

[0022] 5. Through the setting of the suspension conveying rail, this solution can stack and store the box boards outside the manufacturing table, physically isolate them from the chassis platform assembly area, realize the parallel operation of material preparation and main body assembly, shorten the overall production cycle, and at the same time the automated conveying, clamping and deviation correction systems reduce the dependence on skilled workers, effectively reduce the production cost and improve the overall production efficiency.

[0038] Example, refer to Figures 1 to 11 , a production device for the molding and manufacturing of a refrigerated truck, including a manufacturing table 1 and a suspension conveying guide rail 2. The suspension conveying guide rail 2 is an electrically controlled guide rail structure. Three palletizing seats 4 are connected to the top end of the manufacturing table 1. Two opposite control turntables are connected to the top end of the palletizing seat 4. The control turntables are respectively rotatably connected to a plurality of palletizing plates 6 through a plurality of retaining frames 5. Four guiding grooves 7 are formed on the palletizing plate 6. The inner side wall of the guiding groove 7 is connected to a slow support assembly for supporting the refrigerated truck box board through a guiding plate 8. Four corners at the top end of the palletizing seat 4 are respectively connected to a positioning concave plate 14 through a guiding column 13;

[0039] Furthermore, a docking inclined plate 3 is fixedly connected to the side wall of the manufacturing table 1. Two limiting grooves are formed on the top end of the manufacturing table 1. The three palletizing seats 4 are arranged in a U shape. The top end of the manufacturing table 1 is fixedly connected to a fixed frame through a plurality of support rods. The bottom end of the fixed frame is fixedly connected to the suspension conveying guide rail 2. The plurality of retaining frames 5 are arranged in a staggered manner up and down. The four guiding grooves 7 are arranged obliquely in a rectangular array. The inner side wall of the guiding groove 7 is slidably connected to the guiding plate 8. The slow support assembly is composed of a plurality of self-adjusting telescopic rods 9 and a plurality of slow support air cushion pads 10. The top end of the guiding plate 8 is fixedly connected to the slow support air cushion pad 10 through the self-adjusting telescopic rod 9. An inverted table 11 is fixedly connected to the outer side wall of the top end of the self-adjusting telescopic rod 9. An inclined guiding frame 12 is arranged outside the guiding groove 7. The center of the top end of the palletizing plate 6 is fixedly connected to the slow support air cushion pad 10 through an electric push rod. The top end of the palletizing seat 4 is slidably connected to the positioning concave plate 14 through the guiding column 13. The sizes and models of the positioning concave plates 14 on the three palletizing seats 4 are all different and are used to adapt to different box boards of the refrigerated truck box body;

[0040] It should be noted that: the box boards to be assembled and manufactured at different parts of the refrigerated truck box body are respectively placed on the stacking boards 6 on the stacking seats 4. During the placement process, the positioning concave plates 14 adapted to each box board are used for position limitation. Before placing the box board on the multiple slow-support air cushions 10 on the stacking board 6, according to the size of the box board, the position of the guiding plate 8 on the guiding groove 7 is appropriately adjusted, so that the multiple slow-support air cushions 10 can support different-sized box boards more evenly and stably. Different box boards are stacked and stored outside the manufacturing table 1, so that when the overall assembly production of the refrigerated truck box body is carried out, the entire production area is more likely to implement the 5S production management system. Subsequently, when assembling and manufacturing the refrigerated truck box body, the refrigerated truck chassis platform enters the limit groove on the manufacturing table 1 through the docking inclined plate 3 and is limited. When it is necessary to convey the box board on the stacking seat 4 before assembly, first control the positioning concave plate 14 to slide on the guiding column 13 to the periphery of the box board to be taken out to ensure that the box board is in the initially defined position. Subsequently, control the guiding plate 8 to continuously slide inward in the guiding groove 7 (the movement of the guiding plate 8 in the guiding groove 7 is a common movement mode of the electric control guide rail and will not be elaborated here). The sliding of the guiding plate 8 will drive the slow-support air cushion 10 to move outward together through the self-adjusting telescopic rod 9. During the movement of the self-adjusting telescopic rod 9, the inverted table 11 will be driven to move synchronously. After the inverted table 11 moves to the inclined guiding frame 12, as it continues to move, the inverted table 11 continuously slides on the inclined surface of the inclined guiding frame 12 and gradually moves upward, thereby lifting the multiple slow-support air cushions 10 synchronously. The slow-support air cushion 10 in the middle is kept in synchronous support and lifting under the action of the electric push rod, which is convenient for taking away the lifted box board later. After the box board is taken away, let the fixing frame 5 drive the stacking board 6 to rotate, so that the box board on the next stacking board 6 is exposed;

[0041] Based on the above benefits: in this way, the position change of the multiple slow-support air cushions 10 on the stacking board 6 can be used to evenly buffer and support box boards of different sizes, avoiding the superposition of multiple box boards and squeezing and damaging the insulation layer of the box board below. The inverted table 11 slides on the inclined guiding frame 12 to lift the entire box board to a certain height, which is convenient for the subsequent suspension conveying system to convey the box board to the installation position;

[0042] The inner side wall of the suspension conveying rail 2 is connected with a suspension board 16 through a guiding seat 15. Both ends of the bottom of the suspension board 16 are connected with right-angle limit seats 18 through steering robotic arms 17. The top of the right-angle limit seat 18 is connected with two hydraulic push rods 19 in a vertical state. The output end of the hydraulic push rod 19 is connected with a side pressure assembly. There are two magnetic rubber plates 25 arranged on one side of the side pressure assembly;

[0043] Furthermore, the suspension conveying guide rail 2 is in a cross state. The inner side wall of the suspension conveying guide rail 2 is slidably connected to the guide seat 15. The guide seat 15 is rotatably connected to the suspension plate 16 through a rotating shaft. The suspension plate 16 is fixedly connected with a control seat through a lifting suspension rod. The control seat is fixedly connected with a right-angle limit seat 18 through a steering robotic arm 17. The side pressing assembly consists of an adjusting rack 20 and a plurality of side pressing gears 21. The output end of the hydraulic push rod 19 is fixedly connected to the adjusting rack 20. The adjusting rack 20 meshes with a plurality of side pressing gears 21 respectively. The bottom end of the side pressing gear 21 is fixedly connected with a side pressing plate 23 through a pin shaft. Two outer limit plates 22 are fixedly connected to both inner side walls of the right-angle limit seat 18. Grooves are formed on the inner side walls of the outer limit plates 22 facing inwards. The inner end face of the groove is fixedly connected with a magnetic rubber plate 25 through a reset telescopic rod. A buffer electromagnetic plate 24 is fixedly connected to the outer side wall of the outer limit plate 22 facing outwards. A plurality of side pressing plates 23 are placed between the two outer limit plates 22;

[0044] It should be noted that when taking out the box board from the palletizing board 6, the guide seat 15 is controlled to slide in the suspension conveying guide rail 2 to the upper part corresponding to the palletizing seat 4. Subsequently, the two right-angle limit seats 18 are moved to the edge of the box board by using the lifting suspension rods under the suspension plate 16, and the positioning concave plate 14 at this position of the box board is removed. Subsequently, the two outer limit plates 22 in the two right-angle limit seats 18 are clamped at the end edge of the box board. Subsequently, the hydraulic push rod 19 is controlled to start to push the adjusting rack 20. The movement of the adjusting rack 20 will synchronously drive a plurality of side pressing gears 21 to rotate. The rotation of the side pressing gears 21 will synchronously drive a plurality of side pressing plates 23 to rotate together through the pin shaft. The rotation of the mutually perpendicular side pressing plates 23 will press the side of the box board to avoid a large extrusion force on the front and back sides of the box board. Subsequently, the buffer electromagnetic plate 24 is controlled to be energized to generate a magnetic repulsive force on the magnetic rubber plate 25, so that the magnetic rubber plate 25 assists in clamping the box board. The magnetic repulsive force between the buffer electromagnetic plate 24 and the magnetic rubber plate 25 is convenient for buffering during the conveying process;

[0045] The benefits based on the above are as follows: In this way, the side pressing plates 23 after turning can be pressed against the edge position of the box board, avoiding large-pressure damage to the front and back sides of box boards made of different materials. At the same time, the magnetic rubber plate 25 with magnetic repulsive force buffering assists in clamping, avoiding damage to the box board caused by rigid clamping;

[0046] At the center bottom of the suspension plate 16, a two-way electric push rod 27 is connected through a control shaft 26. The output end of the two-way electric push rod 27 is connected to a fixed seat 29 through an arc-shaped bending member 28. The bottom of the fixed seat 29 is connected with a friction test plate 34 through two magnetic limit components. The top end of the friction test plate 34 is connected with a position measuring component through a piston member 33;

[0047] Further, the magnetic limit component is composed of a limit electromagnetic plate 30 and a limit magnetic plate 31. The limit electromagnetic plate 30 is fixedly connected to the bottom end of the fixed seat 29, and the limit magnetic plate 31 is fixedly connected to the top end of the friction test plate 34. The position measurement component is composed of a pressure increasing cylinder 32, a diversion pipe 35, and a test instrument 36. The piston member 33 is slidably connected to the inner side wall of the pressure increasing cylinder 32. The pressure increasing cylinder 32 communicates with the conductive part of the test instrument 36 through the diversion pipe 35. The pressure increasing cylinder 32 is filled with a conductive liquid;

[0048] It should be noted that: Subsequently, the guide seat 15 is controlled to move, and the box board is conveyed to the position to be assembled and manufactured. Then, the box board is placed in a vertical state by using the steering robotic arm 17. Then, the vertically placed box board is slightly lifted upward, and the box board will move between the two friction test plates 34. The magnetic attraction limit of the limit electromagnetic plate 30 and the limit magnetic plate 31 ensures that the initial positions of the friction test plates 34 are the same. Subsequently, the two friction test plates 34 are synchronously controlled by the bidirectional electric push rod 27 to be pressed against the front and back surfaces of the box board, so that the two friction test plates 34 maintain the same positive pressure on the front and back surfaces of the box board. Subsequently, the vertical box board is slowly lifted upward. Since the front surface (outer surface) of the box board is usually rough or has anti-slip textures, while the back surface (inner surface) of the box board is usually smooth and flat, the friction force received by the friction test plate 34 on the front surface of the box board is larger, and the friction force received by the friction test plate 34 on the back surface of the box board is smaller. As a result, the moving distance of the piston member 33 driven by the friction test plate 34 on the front side of the box board is greater than the moving distance of the piston member 33 on the back side of the box board. Then, the conductive liquid in the pressure increasing cylinder 32 on the front side of the box board will be first pressed to the test instrument 36 through the diversion pipe 35, and then it can be determined which side of the box board is the front side. If the front and back surfaces of the box board are inconsistent with the requirements of the installation position at this time, the guide seat 15 controls the suspension plate 16 to rotate 180°, and the front and back surfaces of the box board during the conveying process are guided and corrected. The short-time extrusion limit of the multiple side pressing plates 23 facilitates the smooth suspension and guiding conveyance of the box board;

[0049] Based on the above advantages: In this way, the roughness of the front and back surfaces of the box board conveyed by suspension can be detected by using the friction test plate 34. According to the displacement changes on different rough surfaces under the same state, it is converted into the extrusion change of the liquid in the pressure increasing cylinder 32, which is convenient for guiding and correcting the conveyed box board before assembly, realizing more efficient installation preparation before assembly, and improving the overall production process efficiency of the refrigerated truck box body;

[0050] When the present invention is in use, the box boards to be assembled at different parts of the refrigerated truck box body are respectively placed on the stacking boards 6 on the stacking seats 4. During the placement process, the positioning concave plates 14 adapted to each box board are used for position limitation. Before placing the box board on the plurality of slow-support air cushion pads 10 on the stacking board 6, according to the size of the box board, the position of the guiding plate 8 on the guiding groove 7 is appropriately adjusted, so that the plurality of slow-support air cushion pads 10 can support different-sized box boards more evenly and stably. Different box boards are stacked and stored outside the manufacturing table 1, so that when the overall assembly production of the refrigerated truck box body is carried out, the entire production area is more likely to implement the 5S production management system. Subsequently, when assembling and manufacturing the refrigerated truck box body, the refrigerated truck chassis platform enters the limiting groove on the manufacturing table 1 through the docking inclined plate 3 and is limited. When it is necessary to convey the box board on the stacking seat 4 before assembly, first control the positioning concave plate 14 to slide on the guiding column 13 to the periphery of the box board to be taken out to ensure that the box board is in the initially limited position. Then control the guiding plate 8 to continuously slide inward in the guiding groove 7. The sliding of the guiding plate 8 will drive the slow-support air cushion pads 10 to move outward together through the self-adjusting telescopic rod 9. During the movement of the self-adjusting telescopic rod 9, the inverted table 11 will be driven to move synchronously. After the inverted table 11 moves to the inclined guiding frame 12, as it continues to move, the inverted table 11 continuously slides on the inclined surface of the inclined guiding frame 12 and gradually moves upward, thereby lifting the plurality of slow-support air cushion pads 10 synchronously. The slow-support air cushion pad 10 in the middle is kept synchronously supported and lifted under the action of the electric push rod, which is convenient for taking away the lifted box board later. After the box board is taken away, let the fixing frame 5 drive the stacking board 6 to rotate, so that the box board on the next stacking board 6 is exposed. In this way, the position change of the plurality of slow-support air cushion pads 10 on the stacking board 6 can be used to evenly buffer and support different-sized box boards, avoiding the superposition of multiple box boards and squeezing and damaging the thermal insulation layer of the lower box board. The inverted table 11 slides on the inclined guiding frame 12 to lift the entire box board to a certain height, which is convenient for the subsequent suspension conveying system to convey the box board to the installation position;

[0051] When removing the case board from the palletizing board 6, control the guide seat 15 to slide in the hanging conveyor rail 2 to the position above the corresponding palletizing seat 4. Then, use the lifting hanging rod under the hanging plate 16 to move the two right-angle limit seats 18 to the edge of the case board, and remove the positioning concave plate 14 at this position of the case board. Subsequently, make the two outer limit plates 22 in the two right-angle limit seats 18 clamp on the end edge of the case board. Then, control the start of the hydraulic push rod 19 to push the adjustment rack 20. The movement of the adjustment rack 20 will synchronously drive the rotation of multiple side pressure gears 21. The rotation of the side pressure gears 21 will synchronously drive the rotation of multiple side pressing plates 23 through the pin shafts. The rotation of the multiple mutually perpendicular side pressing plates 23 will press the side of the case board, avoiding a large squeezing force on the front and back sides of the case board. Then, control the energization of the buffer electromagnetic plate 24 to generate a magnetic repulsion force on the magnetized rubber plate 25, so that the magnetized rubber plate 25 assists in clamping the case board. The magnetic repulsion force between the buffer electromagnetic plate 24 and the magnetized rubber plate 25 is convenient for buffering during the conveying process. In this way, the turned side pressing plates 23 can be pressed on the edge position of the case board, avoiding damage to the front and back sides of the case board made of different materials due to large pressure. At the same time, the magnetized rubber plate 25 with magnetic repulsion buffering assists in clamping, avoiding damage to the case board caused by rigid clamping;

[0052] Subsequently, control the movement of the guiding seat 15 to convey the box board to the position to be assembled and manufactured. Then, use the steering robotic arm 17 to place the box board in a vertical state. Next, slightly move the vertically placed box board upward, and the box board will move between the two friction test plates 34. The magnetic attraction limit of the limit electromagnetic plate 30 and the limit magnetic plate 31 ensures that the initial positions of the two friction test plates 34 are the same. Subsequently, synchronously control the two friction test plates 34 to press against the front and back surfaces of the box board through the bidirectional electric push rod 27, so that the two friction test plates 34 maintain the same positive pressure on the front and back surfaces of the box board. Then, slowly move the vertical box board upward. Since the front surface (outer surface) of the box board is usually rough or has anti-slip textures, while the back surface (inner surface) of the box board is usually smooth and flat, the friction force received by the friction test plate 34 on the front surface of the box board is larger, and the friction force received by the friction test plate 34 on the back surface of the box board is smaller. As a result, the moving distance of the piston part 33 driven by the friction test plate 34 on the front side of the box board is greater than the moving distance of the piston part 33 on the back side of the box board. Then, the conductive liquid in the pressure increasing cylinder 32 on the front side of the box board will first be pressed to the test instrument 36 through the diversion pipe 35, thereby determining which side of the box board is the front side. If the front and back surfaces of the box board are inconsistent with the requirements of the installation position at this time, the guiding seat 15 controls the suspension plate 16 to rotate 180°, guiding and correcting the front and back surfaces of the box board during the conveying process. The short-term extrusion limit of the multiple side pressing plates 23 facilitates the smooth suspension and guiding conveyance of the box board. In this way, the roughness of the front and back surfaces of the box board conveyed by suspension can be detected by the friction test plates 34. According to the displacement changes on different rough surfaces under the same conditions, it is converted into the extrusion change of the liquid in the pressure increasing cylinder 32, which is convenient for guiding and correcting the conveyed box board before assembly, achieving more efficient installation preparation before assembly, and improving the overall production process efficiency of the refrigerated truck box body.
