[0032] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0033] This specific embodiment details the hot riveting equipment for plastic columns on a vacuum forming board as described in this application, such as... Figures 1-12As shown, the thermoforming plastic column hot riveting equipment includes: a main line 1, a lifting mechanism 2, a blocking mechanism 3, a three-axis gantry mechanism 4, and a hot riveting assembly 5. A thermoforming board 20 can be placed on the carrier 10. The carrier 10 can be placed on the main line 1 and moved from the inlet end of the main line 1 to the outlet end of the main line 1 under the drive of the main line 1. The blocking mechanism 3 and the lifting mechanism 2 are located below the main line 1. The blocking mechanism 3 is provided with a blocking end that can move up and down. The side wall of the carrier 10 can abut against the blocking end of the blocking mechanism 3. The lifting mechanism 2 can lift the carrier 10 off the main line 1 or put the carrier 10 back on the main line 1. The three-axis gantry mechanism 4 and the hot riveting assembly 5 are located above the main line 1. The hot riveting assembly 5 is fixed to the moving end of the three-axis gantry mechanism 4. The hot riveting assembly 5 can approach the plastic column on the thermoforming board 20 under the drive of the three-axis gantry mechanism 4. The hot riveting assembly 5 can melt and squeeze the plastic column on the thermoforming board 20. The carrier 10, on which the blister pack 20 is placed, is moved by the main line 1. After the carrier 10 is positioned by the blocking mechanism 3, the lifting mechanism 2 lifts the carrier 10 off the main line 1. In this way, the three-axis gantry mechanism 4 can drive the hot riveting assembly 5 to sequentially hot rivet the plastic columns on the blister pack 20, realizing automated riveting of the blister pack 20. Compared with manual riveting, it has lower labor costs, and because the entire riveting process is fully automated, the riveting accuracy and consistency are also higher. It has the advantage of a high degree of automation.

[0034] Optionally, this embodiment also includes a base 6, which is rectangular. Columns 7 are vertically fixed at the four corners of the top surface of the base 6. A fixing plate 61 is provided inside the base 6. The lifting mechanism 2 and the blocking mechanism 3 are fixed to the fixing plate 61, and the three-axis gantry mechanism 4 is fixed to the top of the column 7.

[0035] Optionally in this embodiment, the main line 1 includes two fixed seats 11, a rotating shaft 12, a transmission wheel 13, a sprocket, a first transmission chain 14, a second transmission chain 15, a transmission shaft 16, and a motor 17. The fixed seats 11 are hollow inside, and the middle part of the rotating shaft 12 is rotatably connected to the fixed seat 11. Each fixed seat 11 has at least two rotating shafts 12, which are spaced apart along the Y-axis. The rotating shafts 12 on the two fixed seats 11 are arranged opposite to each other. The first end of the rotating shaft 12 is located inside the fixed seat 11. The sprocket and the first end of the rotating shaft 12 are coaxially connected. Each fixed seat 11 has a sprocket. The second ends of two rotating shafts 12 located at the feed end of the main line 1 are connected by a transmission chain 14. The second ends of the remaining rotating shafts 12 are coaxially connected to transmission wheels 13. The output shaft of the motor 17 is connected to any one of the sprockets by a second transmission chain 15. The bottom surface of the carrier 10 can be placed on the transmission wheel 13. The motor 17 can drive the sprocket to rotate and drive the transmission wheel 13 to rotate. A support column 18 is provided between the two fixed seats 11. A ball is rotatably connected to the top of the support column 18. The bottom surface of the carrier 10 can abut against the ball. When the carrier 10 needs to move, the motor 17 drives the sprocket to rotate via the second transmission chain 15. Since all the sprockets on a single fixed seat 11 are interconnected via the first transmission chain 14, when one sprocket rotates, the other sprockets will rotate together. Simultaneously, the rotation of the sprocket drives the rotating shaft 12 and the transmission wheel 13, which are coaxially connected to the sprocket, to rotate together. The rotating shafts 12 on both fixed seats 11 are connected via the transmission shaft 16. Thus, when the rotating shaft 12 on one fixed seat 11 rotates, it drives the rotating shaft 12, transmission wheel 13, and sprocket on the other fixed seat 11 to rotate together. When the bottom surface of the carrier 10 rests on the transmission wheel 13, the rotating transmission wheel 13 drives the carrier 10 towards the discharge end of the main line 1. At the same time, the bottom surface of the carrier 10 can abut against the ball bearings, allowing the support column 18 to support the carrier 10 and prevent it from bending due to its own weight. In this embodiment, the X-axis and Y-axis are perpendicular to each other but parallel to the ground, and the Z-axis is perpendicular to the ground.

[0036] Optionally, in this embodiment, motor 17 is a servo motor.

[0037] Optionally in this embodiment, the blocking mechanism 3 includes a first cylinder, a blocking seat, and a first roller. The first cylinder is vertically fixed to the fixed plate 61, the blocking seat is fixed to the cylinder rod of the first cylinder, and the first roller is rotatably connected to the side of the blocking seat facing the carrier 10. The first roller is the blocking end of the blocking mechanism 3. The blocking seat and the first roller can move up and down along the Z-axis under the drive of the first cylinder, and the side wall of the carrier 10 can abut against the first roller. When it is necessary to block the carrier 10, the cylinder rod of the first cylinder extends, and the blocking seat and the first roller move upward under the drive of the first cylinder. At this time, the side wall of the carrier 10 can just abut against the first roller, so that the first roller can block the carrier 10 and stop the carrier 10. When it is necessary for the carrier 10 to pass, the cylinder rod of the first cylinder retracts. At this time, the blocking seat and the first roller are located below the carrier and will not affect the passage of the carrier 10. Setting the blocking mechanism 3 can ensure that the carrier 10 stops at a predetermined position so that the carrier 10 can be lifted up later.

[0038] Optionally in this embodiment, the lifting mechanism 2 includes a sliding plate 21, a second cylinder 22, a top block 23, a top plate 24, an optical axis 28, a linear bearing 25, and a second roller 26. The sliding plate 21 is slidably connected to the top surface of the fixed plate 61 via a first slide rail 27. The second cylinder 22 is fixed to the fixed plate 61, and the cylinder rod of the second cylinder 22 is connected to the sliding plate 21. The top plate 24 is located above the sliding plate 21, and the optical axis 28 is fixed to the bottom surface of the top plate 24. The linear bearing 25 is fixed to the top surface of the fixed plate 61, and the fixed plate 61 passes through the inner ring of the corresponding linear bearing 25. A clearance hole is provided for the optical axis 28 to pass through. The optical axis 28 is slidably connected to the linear bearing 25. The top block 23 is fixed to the top surface of the slide plate 21. The top of the top block 23 is provided with an inclined surface. The second roller 26 is rotatably connected to the bottom surface of the top plate 24. The second roller 26 can abut against the inclined surface. The slide plate 21 and the top block 23 can move back and forth along the X-axis under the drive of the second cylinder 22. The inclined surface can squeeze the second roller 26 and push the top plate 24 upward away from the slide plate 21. The carrier 10 and the vacuum forming plate 20 can be separated from the main line 1 under the push of the top plate 24. In this embodiment, the top and bottom ends of the inclined surface of the top block 23 are the top and bottom ends, respectively, with the top end being higher than the bottom end. In the initial state, when the carrier 10 is not lifted, the second roller 26 is located at the bottom end of the inclined surface. When it is necessary to lift the carrier 10, the second cylinder 22 drives the slide plate 21 and the top block 23 to move along the X-axis. At this time, the top end of the inclined surface gradually approaches the second roller 26. Since the top end of the inclined surface is higher than the bottom end, the second roller 26 gradually moves upward under the push of the inclined surface and drives the top plate 24 to move upward away from the slide plate 2. The upward-moving top plate 24 lifts the carrier 10 from the main line 1, thereby lifting the carrier 10.

[0039] Optionally, this embodiment also includes a pressure plate mechanism 9, which includes a third cylinder 91, a pressure plate 92, a second slide rail 93, a connecting seat 94, and a fixed frame 95. Each column 7 is fixed with a connecting seat 94. The second slide rail 93 is vertically fixed to the connecting seat 94. The fixed frame 95 is a rectangular frame structure. The pressure plate 92 is fixed to the bottom surface of the fixed frame 95. A connecting plate 96 is fixed to the side wall of the fixed frame 95. One connecting plate 96 corresponds to two second slide rails 93. The connecting plate 96 is slidably connected to the second slide rail 93. The third cylinder 91 is fixed to the connecting seat 94. The cylinder rod of the third cylinder 91 is connected to the connecting plate 96. The fixed frame 95 and the pressure plate 92 can move up and down along the Z-axis under the drive of the third cylinder 91. The pressure plate 92 is provided with a clearance opening for the plastic column to extend out. Before hot riveting, the top surface of the blister panel 20 is covered with the component to be riveted to it. Since the two are not yet riveted together and are in a moving state, they may wobble during the riveting process, causing misalignment. Therefore, before hot riveting, four third cylinders 91 drive the pressure plate 92 downward and make the pressure plate 92 fit tightly against the blister panel 20 and the component to be assembled, so that the blister panel 20 and the component to be assembled are in close contact with each other, avoiding the blister panel 20 and the component to be assembled from wobble, which would affect the riveting accuracy. Since the pressure plate 92 has a clearance opening, the plastic column on the blister panel 20 can protrude from the clearance opening, so the pressure plate 92 will not affect the riveting. In this embodiment, the pressure plate 92 is detachably fixed to the fixing frame 95 by bolts, so the user can adapt the blister panel 20 of different sizes by replacing the pressure plate 92 of different sizes.

[0040] Optionally in this embodiment, a top fixing plate 8 is fixed to the top of the column 7. There are two three-axis gantry mechanisms 4, arranged side-by-side. Each three-axis gantry mechanism 4 includes an electric variable-pitch slide 41, a first electric lead screw module 42, and a second electric lead screw module 43. The electric variable-pitch slide 41 is fixed to the top surface of the top fixing plate 8. The electric variable-pitch slide 41 has two moving ends that can move closer or further apart from each other. Two first electric lead screw modules 42 are fixed to the moving ends of each electric variable-pitch slide 41. The second electric lead screw module 43 is fixed to the moving end of the first electric lead screw module 42, and the hot riveting assembly 5 is fixed to the moving end of the second electric lead screw module 43. The first electric lead screw module 42, the second electric lead screw module 43, and the hot riveting assembly 5 can move back and forth along the X-axis under the drive of the electric variable pitch slide 41. The second electric lead screw module 43 and the hot riveting assembly 5 can move back and forth along the Y-axis under the drive of the first electric lead screw module 42. The hot riveting assembly 5 can move back and forth along the Z-axis under the drive of the second electric lead screw module 43. In this embodiment, multiple plastic columns are provided on the blister plate 20. Because the electric variable pitch slide has two moving ends, it can provide twice the number of hot riveting assemblies 5 compared to an electric lead screw module with only one moving end, thus improving riveting efficiency.

[0041] Optionally in this embodiment, the hot riveting assembly 5 includes an adjusting plate 51, a third slide rail 52, and two hot riveting modules. The adjusting plate 51 is fixed to the moving end of the second electric screw module 43, and the third slide rail 52 is fixed to the adjusting plate 51 along the X-axis. One hot riveting module is fixedly connected to the adjusting plate 51, and the other hot riveting module is slidably connected to the third slide rail 52. An adjusting screw 53 is rotatably connected to the hot riveting module fixed to the adjusting plate 51. The first end of the adjusting screw 53 is threadedly connected to the hot riveting module located at the third slide rail 52, and the second end of the adjusting screw 53 is provided with an internal hexagonal groove for connecting a wrench. The hot riveting module includes an adjusting seat 54, a fourth cylinder 55, a heating assembly 56, an air pipe 57, and... The rivet joint 58 and the fourth cylinder 55 are fixed to the adjusting seat 54. The top of the heating component 56 is fixed to the cylinder rod of the fourth cylinder 55. The rivet joint 58 is fixed to the bottom of the heating component 56. The bottom of the air pipe 57 is connected to the rivet joint 58, and the top of the air pipe 57 is connected to the air source. The side wall of the rivet joint 58 is provided with a ventilation groove 59, and the bottom of the rivet joint 58 is provided with a semi-circular groove. The heating component 56 and the rivet joint 58 can move back and forth along the Z-axis under the drive of the fourth cylinder 55. The heating component 56 can heat the rivet joint 58. The bottom of the rivet joint 58 can melt and squeeze the plastic column on the blister plate 20. The cooling gas can enter the rivet joint 58 through the air pipe 57 and then be discharged through the ventilation groove 59. A hot riveting assembly 5 is equipped with two hot riveting modules that can simultaneously rivet two plastic pillars, thereby improving riveting efficiency. Since the spacing between plastic pillars of different specifications of vacuum forming panels 20 is different, it is necessary to adjust the distance between the two hot riveting modules. When it is necessary to adjust the distance between the two hot riveting modules, the user only needs to connect a hex wrench to the inner hexagonal groove of the adjusting screw 53, and then turn the adjusting screw 53 clockwise or counterclockwise with the hex wrench. In this way, the hot riveting module that is screwed to the adjusting screw 53 can move closer to or further away from the hot riveting module fixed to the adjusting plate 51, thereby adjusting the distance between the two hot riveting modules. The circular groove at the bottom of the riveting joint 58 is used for the plastic pillar to be shaped after melting. When the plastic pillar melts, the cooling gas enters the riveting joint 58 through the air pipe 57 and is discharged through the vent groove 59. In this way, the cooling gas can carry away the heat of the riveting joint 58, so that the riveting joint 58 is cooled quickly and the melted plastic pillar is shaped, thereby completing the riveting.

[0042] Optionally, this embodiment also includes a return line 30, which is fixed to the base 6 and located below the main line 1. The return line 30 and the main line 1 have the same structure. In this embodiment, the return line 30 can drive the carrier 10 and the thermoforming plate 20 to move in a direction opposite to the main line 1.

[0043] The function of the hot riveting equipment for the plastic columns of the vacuum forming panel in this embodiment is to fix the vacuum forming panel 20 and the assembly parts to be fixed to the vacuum forming panel 20 through a hot riveting process. In this embodiment, multiple plastic columns are provided on the top surface of the vacuum forming panel 20, and the assembly parts are provided with riveting holes that can be fitted onto the plastic columns. The specific operation process is as follows: before hot riveting, the assembly parts to be riveted to the vacuum forming panel 20 are placed on the top surface of the vacuum forming panel 20, and the top of the plastic column is made to pass through the riveting hole. Then, the vacuum forming panel 20 is placed on the carrier 10, and then the carrier 10 is placed on the... At the inlet end of the main feed line 1, the carrier 10 and the blister plate 20 move towards the outlet end of the main feed line 1 under the drive of the main feed line 1. Then, the first cylinder drives the blocking seat and the first roller to move upward along the Z-axis. Then, the side wall of the carrier 10 on the main feed line 1 abuts against the first roller to stop the carrier 10 from moving. Then, the second cylinder 22 drives the top plate 24 to move upward along the Z-axis. The top plate 24 lifts the carrier 10 off the main feed line 1. Then, the third cylinder 91 drives the pressure plate 92 to descend along the Z-axis. The pressure plate 92 squeezes the blister plate 20 and the parts to be assembled tightly. After the plastic column is attached to the plastic column, the electric variable pitch slide 41, the first electric lead screw module 42, and the second electric lead screw module 43 work together to drive the hot riveting assembly 5 to move directly above the plastic column. Then, the heating assembly 56 heats up and heats the riveting joint 58. Then, the cylinder rod of the fourth cylinder 55 extends and drives the heated riveting joint 58 to move downward along the Z-axis. After the bottom end of the riveting joint 58 contacts the plastic column, the plastic column melts. The melted plastic column fills the semi-circular groove at the bottom end of the riveting joint 58. Then, the heating assembly 56 stops heating, and cooling gas is introduced into the riveting joint through the air pipe 57. The internal cooling riveting joint 58 and the melted plastic column are then cooled and reshaped to form a mushroom head with the same shape as the semi-circular groove. The mushroom head can prevent the blister plate 20 from separating from the part to be assembled, thereby fixing the blister plate 20 and the part to be assembled. After the hot riveting is completed, the lifting mechanism 2 puts the carrier 10 back into the main line 1. Then the first cylinder drives the first roller to reset. Then the main line 1 drives the riveted blister plate 20 to move to the discharge end of the main line 1. This process is repeated to realize the automated hot riveting of the blister plate 20.

[0044] The thermoforming plastic column hot riveting equipment used in this embodiment has the advantage of a high degree of automation.
