Description

Technical Field

[0001] This invention relates to the field of pressure holding devices, specifically a single-rail three-station pressure holding device. Background Technology

[0002] In industrial applications, after adhesive is applied to products, pressure holding is required to improve the curing effect of the adhesive. Existing pressure holding devices use a conveyor line to transport fixtures, and a pressure holding mechanism is set along the conveyor line to hold the product in the fixture under pressure. The conveyor line is a fixed structure, which means that the conveyor line cannot be adjusted in a timely manner according to the size of the fixture, and it cannot be adapted to different fixtures, thus reducing the application scenarios of the device.

[0003] For example, Chinese patent CN119381471B discloses a dispensing and bonding device for hydrogen fuel cell electrode plates with continuous pressure holding function. This device includes a continuous pressure holding bonding table positioned beside a dispensing robot and a feeding robot. The continuous pressure holding bonding table includes a limiting template, a linear conveyor, pressure holding limiting devices, an unlocking adjustment device, a lifting and pushing device, a pressure holding and pushing device, and a protective plate placement device. The limiting template is horizontally mounted on a frame. The linear conveyor is installed below the limiting template. Multiple pressure holding limiting devices are provided and distributed on the linear conveyor, with multiple limiting clamps on the top of each device. The lifting and pushing device is positioned directly below the limiting template. The pressure holding and pushing device is positioned below the lifting and pushing device. Multiple unlocking and adjustment devices are provided and distributed below the limiting template. The protective plate placement device is positioned beside the limiting template. The conveying distance of the linear conveyor described above is not adjustable, and it can only convey fixtures at a fixed conveying distance, thus limiting the size of the fixtures that can be conveyed.

[0004] Therefore, it is necessary to provide a single-rail three-station pressure holding device. Summary of the Invention

[0005] The present invention provides a single-rail three-station pressure holding device, which effectively solves the problem that the conveyor line of the pressure holding device cannot be variable pitch.

[0006] The technical solution adopted in this invention is:

[0007] A single-rail three-station pressure holding device includes a frame and several fixtures, as well as a conveyor line mounted on the frame and three pressure holding mechanisms mounted on the frame along the conveyor line's conveying direction. The conveyor line includes a first support line fixedly mounted on the frame, a linear guide rail mounted on the frame along the Y-axis, a second support line slidably mounted on the linear guide rail, and a drive assembly fixedly mounted on the frame for driving the second support line to slide. The first and second support lines respectively support the two sides of the lower end face of the fixture.

[0010] Furthermore, the motor belt conveyor line includes a driving wheel, a driven wheel, several tensioning wheels, a No. 1 motor for driving the driving wheel to rotate, and a belt, which are installed inside the No. 2 support. The belt is connected by the driving wheel, the driven wheel and the tensioning wheels. The distance between adjacent motor belt lines is less than one-tenth of the fixture length.

[0011] Furthermore, the pressure holding mechanism includes a lifting assembly mounted on the frame and a pressure holding assembly mounted on the frame above the conveyor line. The lifting assembly includes a fixed plate mounted on the frame, several linear bearings mounted vertically on the fixed plate, several lifting rods slidably connected to the linear bearings, a lifting plate connected to the upper ends of the lifting rods, and an electric cylinder mounted on the fixed plate for driving the lifting plate to rise and fall.

[0012] Furthermore, the pressure-holding assembly includes a mounting plate mounted on the frame, a connecting frame mounted on the upper surface of the mounting plate, and several elastic pressure components fixedly mounted on the connecting frame and slidably connected to the mounting plate.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 5 As shown, the single-rail three-station pressure-holding device provided in the embodiments of this application includes a frame 1 and several fixtures 2, as well as a conveyor line disposed on the frame 1 and three pressure-holding mechanisms 3 disposed on the frame 1 along the conveying direction of the conveyor line. Figure 2 , Figure 3 As shown, the conveyor line includes a first support line 4 fixedly mounted on the frame 1, a linear guide rail 6 mounted on the frame 1 along the Y-axis, a second support line 5 slidably mounted on the linear guide rail 6, and a drive assembly 7 fixedly mounted on the frame 1 for driving the second support line 5 to slide. The first support line 4 and the second support line 5 respectively support the two sides of the lower end face of the fixture 2.

[0024] In actual use, the spacing between the first support line 4 and the second support line 5 is adjusted by the drive component 7, so that the first support line 4 and the second support line 5 are positioned to transport the fixture 2. The fixture 2 is transported by the conveyor line and passes through three pressure holding mechanisms 3 in sequence for three pressure holding cycles.

[0025] In the above design, the conveyor line can transport jigs 2 of different models and sizes, and can adapt to different products.

[0026] Specifically: such as Figure 2 and Figure 3 As shown, the drive assembly 7 includes a first seat 71 mounted on the frame 1, two sets of lead screw and nut pairs 72 mounted on the first seat 71, and a drive component 73 for driving the two sets of lead screws synchronously. The lead screw and nut pairs 72 include lead screws and nuts threadedly connected to the lead screws. The nuts of the two sets of lead screw and nut pairs 72 are respectively connected to both ends of the second support line 5. The drive component 73 includes two lead screw mounting seats 731 mounted at both ends of the first seat 71, two synchronous pulleys 732 coaxially fixed on the two lead screws, a synchronous belt 733 drivingly connected to the two synchronous pulleys 732, and a handwheel 734 coaxially fixed to one end of the lead screw.

[0027] When adjusting the second support line 5, the screw connected to the handwheel 734 is rotated by turning the handwheel 734. With the cooperation of the two synchronous pulleys 732 and the synchronous belt 733, the other screw rotates synchronously. The rotation of the screw causes the two nuts to move along the axial direction of the screw. The nuts drive the second support line 5 to move along the axis, thereby changing the distance between the first support line 4 and the second support line 5.

[0028] In the above design, the structural design and specific implementation of the drive component 7 facilitate the adjustment of the spacing between the first support line 4 and the second support line 5.

[0029] Specifically: such as Figure 3 and Figure 4As shown, the second support line 5 includes a second support 51 and three second motor belt conveyor lines 52 arranged along the X direction on the second support 51. The first support line 4 includes a first support 41 and a first motor belt conveyor line 41 arranged on the first support 41 corresponding to the second motor belt conveyor line 52. The second support 51 is connected to a nut.

[0030] In actual use, the corresponding No. 1 motor belt conveyor line 41 and No. 2 motor belt conveyor line 52 transport the fixture 2.

[0031] In the above design, the structural design and specific implementation of the No. 2 support line 5 and the No. 1 support line 4 can effectively realize the transportation of the jig 2.

[0032] Specifically: such as Figure 4 As shown, the second motor belt conveyor line 52 includes a driving wheel 522, a driven wheel 523, several tensioning wheels 524, a first motor 521 for driving the driving wheel 522 to rotate, and a belt 525, which are arranged inside the second support 51. The belt 525 is connected by the driving wheel 522, the driven wheel 523 and the tensioning wheels 524. The distance between adjacent motor belts 525 is less than one-tenth of the length of the fixture 2.

[0033] In actual use, the drive wheel 522 is driven by the first motor 521 to rotate. With the cooperation of the driven wheel 523 and the tension wheel 524, the belt 525 is used to drive the jig 2. Since the spacing between adjacent motor belts 525 is less than one-tenth of the length of the jig 2, the jig 2 can move smoothly from one motor belt 525 conveyor line to an adjacent motor belt 525 conveyor line.

[0034] In the above design, the structure and specific implementation of the No. 2 motor belt conveyor line 52 can realize the conveying of the jig 2.

[0035] Specifically: such as Figure 5 As shown, the pressure holding mechanism 3 includes a lifting assembly 31 mounted on the frame 1 and a pressure holding assembly 32 mounted on the frame 1 above the conveyor line. The lifting assembly 31 includes a fixed plate 311 mounted on the frame 1, a plurality of linear bearings 312 mounted vertically on the fixed plate 311, a plurality of lifting rods 313 slidably connected to the linear bearings 312, a lifting plate 314 connected to the upper ends of the plurality of lifting rods 313, and an electric cylinder 315 mounted on the fixed plate 311 for driving the lifting plate 314 to rise and fall.

[0036] It should be noted that the conveyor line is equipped with three stop components, each corresponding to one of the three pressure-holding mechanisms 3, used to stop the fixture 2 in the conveyor line. After stopping, the lifting component 31 then lifts the fixture 2.

[0037] In actual use, the lifting assembly 31 lifts the fixture 2, ensuring the product in the fixture 2 is tightly pressed against the pressure-holding assembly 32 to achieve pressure holding. After pressure holding is complete, the lifting assembly 31 lowers, returning the fixture 2 to the conveyor line. During lifting, the electric cylinder 315 drives the lifting plate 314 to rise, causing the lifting plate 314 to simultaneously lift the lifting rod 313. The lifting plate 314 then lifts the fixture 2 from the conveyor line until the product reaches the pressure-holding height. During lowering, the electric cylinder 315 drives the lifting plate 314 to descend, causing the lifting plate 314 to move the fixture 2 down to re-engage with the conveyor line.

[0038] In the above design, the structural design and specific implementation of the lifting component 31 can effectively realize the lifting and lowering of the fixture 2.

[0039] Specifically: such as Figure 5 and Figure 6 As shown, the pressure-holding assembly 32 includes a mounting plate 321 mounted on the frame 1, a connecting frame 324 mounted on the upper surface of the mounting plate 321, and a plurality of elastic pressure components 322 fixedly mounted on the connecting frame 324 and slidably connected to the mounting plate 321. The mounting plate 321 has a through hole for sliding with the elastic pressure components. The elastic pressure component 322 includes a pressure head 3221 slidably mounted on the through hole, a limiting plate 3222 mounted on the pressure head 3221, a pressure sensor 3223 mounted on the mounting plate 321 with its sensing end facing downwards, and elastic elements 3224 whose two ends respectively abut against the sensing ends of the pressure sensor 3223 and the upper end of the pressure head 3221. A step is provided on the through hole to cooperate with the limiting plate 3222. The step abuts against the limiting plate 3222 to prevent the elastic pressure component 322 from sliding down the through hole.

[0040] In actual use, as the product in fixture 2 rises, it comes into contact with the lower end of the pressure head 3221, which in turn drives the pressure head 3221 to rise. This causes the elastic element 3224 to compress and squeeze the pressure sensor 3223. The pressure sensor 3223 senses the pressure value of the product. When the PLC control system detects that the value of the pressure sensor 3223 has reached the required value, it stops controlling the lifting mechanism to drive the fixture 2 to rise.

[0041] In the above design, the structural design and specific implementation of the pressure holding component 32 can effectively control the pressure holding of the product, while the elastic element 3224 can buffer the product when it comes into contact with the pressure head 3221.

[0042] Specifically: such as Figure 5 As shown, the pressure holding assembly 32 also includes a buffer 323 disposed at the lower end of the mounting plate 321.

[0043] In actual use, when the product is under pressure, the upper surface of the fixture 2 will abut against the buffer 323.

[0044] In the above design, buffer 323 can be set to buffer the jig 2 during the rising process.

[0045] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
