Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to a small strip automatic coating loading device. Background Technology

[0002] Coating can form a protective film on the surface of a plate, enhancing its wear resistance, corrosion resistance, or oxidation resistance, and extending the service life of the plate. If the coating is an optical thin film, it can change the light transmittance, reflectance, or absorptivity of the plate to meet specific optical requirements, such as for small long strip lenses or filter components in optical instruments.

[0003] A fully automatic coating machine with publication number CN107841726B includes a loading device, a return device, and a unloading device. The loading device is connected to the inlet end of the coating equipment, and the unloading device is connected to the outlet end of the coating equipment. A conveyor belt passes through the coating equipment, and its two ends extend into the loading device and the unloading device, respectively. The return device is located below the coating equipment.

[0004] A coating line loading and unloading system with publication number CN220033338U includes a manual loading table, a tempered sheet stacking table, a tempered sheet loading table, a first large plate bidirectional transfer table, a large plate loading table, a first unidirectional transfer table, a first middle plate bidirectional transfer table, a middle plate loading table, a second unidirectional transfer table, a second middle plate bidirectional transfer table, a middle plate unloading table, a second large plate bidirectional transfer table, a large plate unloading transfer table, a large plate unloading table, a tempered sheet sorting table, a tempered sheet unloading table, and a manual unloading table.

[0005] In existing coating and loading equipment, most use a single loading component. The loading process is prone to interruption due to material replenishment. The equipment station design is mostly linear, making it difficult to process loading, clamping, and conveying processes in parallel. For example, the connection between unloading and conveying processes is time-consuming. Summary of the Invention

[0006] (a) Technical problems to be solved The purpose of this invention is to provide a small strip automatic coating and loading device in order to solve the above-mentioned problems.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an automatic coating and loading device for small strips, comprising a plurality of strip clamping wheel structures for clamping the strips and a station rotation drive assembly having four or more stations for driving each strip clamping wheel structure to rotate. During the process of the station rotation drive assembly driving the rotation of each strip clamping wheel structure, the first station and the second station are respectively equipped with a first strip loading assembly and a second strip loading assembly for feeding the strip into the strip clamping wheel structure for clamping, and the third station is equipped with a push plate conveyor for pushing the strip out of the clamping state of the strip clamping wheel structure for transmission.

The outer cover covers the outside of the first lead screw. A horizontal pushing structure for horizontally pushing the strip is provided on the upper side of the first loading box.

[0014] Furthermore, the flat push structure includes a support slide on one side of the upper part of the first feeding box. The support slide has an opening slot on the side facing the middle of the station rotation drive assembly for passing through the strip clamping wheel structure. Two first cylinders are fixedly installed on the first feeding box by a bracket. Each first cylinder has a pusher plate fixedly connected to the push rod head. A hanging strip is provided on the lower side of the pusher plate opposite to the station rotation drive assembly.

[0015] Furthermore, the second strip loading assembly includes a second support frame, which is fixedly mounted on the side beam of the frame. A fixing rod is fixedly connected between the first support frame and the second support frame. The second loading box is fixed on the fixing rod. The second loading box is U-shaped with an opening at the top. A second push block is slidably mounted inside the second loading box.

Guide columns that cooperate with the first guide grooves to guide the sliding are fixedly mounted at both ends of the second push block. The second loading box is provided with a vertical push structure for vertically pushing the strip from inside the second loading box.

[0016] Furthermore, the vertical push structure includes a second U-shaped bracket fixedly mounted on the second feeding box. A second cylinder is mounted on the second U-shaped bracket. The push rod of the second cylinder faces downward and is fixedly connected to an L-shaped push plate. Two or more abutment rollers are provided at the discharge port of the second feeding box. Each abutment roller has a wheel rod at both ends. Two or more second adjusting bolts are threaded to both sides of the second feeding box. A second adjusting groove is provided on the wheel rod for sliding through the second adjusting bolt. When the connection between the second adjusting bolt and the second feeding box is loosened, the relative sliding adjustment between the second feeding box and the wheel rod can be realized, thereby adjusting the distance between the abutment roller and the second feeding box. A second guide groove is provided on the wheel rod. A guide slider is slidably mounted in the second guide groove. The two ends of the abutment roller are rotatably mounted between the two guide sliders. One end of a second guide rod is fixedly connected to the guide slider. The other end of the second guide rod is slidably connected to a second guide hole at the corresponding position of the wheel rod end. A second spring is sleeved on the outside of the second guide rod.

[0017] (III) Beneficial Effects Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the coordination and cooperation between the strip clamping wheel structure, the station rotation drive assembly, the push plate conveyor, the first strip loading assembly and the second strip loading assembly, etc., multi-station transmission can be realized. The loading can be completed by two loading assemblies, one main and one auxiliary. The third station completes the unloading and equidistant transmission through the push plate conveyor, and the unloading and equidistant transmission can be carried out synchronously. 2. The strip clamping wheel structure can adjust the distance between the clamping plate and the elastic clamping structure through the cooperation of the first adjusting bolt and the first adjusting slide groove. The design of the first spring, clamping wheel and trapezoidal anti-slide groove of the elastic clamping structure can adapt to the elastic clamping of strips of different thicknesses. The distance of the abutment wheel of the second strip loading assembly can also be adjusted by the second adjusting bolt. The whole equipment can flexibly adapt to small and long strip workpieces of various sizes. 3. The two synchronous conveyor belts of the pusher conveyor are provided with evenly distributed protrusions on the outside. The protrusions can push the strips out of the clamping structure and also abut against the strips during the transmission process, ensuring that the strips are evenly distributed on the conveyor belt and avoiding the impact of uneven spacing on subsequent coating processes. 4. The first and second loading components work together as a main and auxiliary unit. When the first loading component needs to be replenished or malfunctions, the second loading component can continue to feed materials, thus avoiding production stoppages caused by the interruption of a single component and ensuring the continuity of the feeding process.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] See Figures 1-13As shown, the present invention provides a small strip automatic coating loading device, including a plurality of strip clamping wheel structures 1 for clamping strips and a station rotation drive assembly 2 for driving each strip clamping wheel structure 1 to rotate and having four or more stations, and also includes a digital display control panel 6; during the process of the station rotation drive assembly 2 driving each strip clamping wheel structure 1 to rotate, a first strip loading assembly 4 and a second strip loading assembly 5 are respectively provided at the first station and the second station for feeding the strips into the strip clamping wheel structure 1 for clamping, and a pusher conveyor 3 is provided at the third station for pushing the strips out of the clamping state of the strip clamping wheel structure 1 for transmission; the pusher conveyor 3 includes a conveyor belt 304, and a plurality of evenly distributed protrusions 305 are provided on the outer side of the conveyor belt 304 along its transmission direction. When the conveyor belt 304 drives the protrusions 305 to move, the protrusions 305 can push the strips out from the clamping state of the strip clamping wheel structure 1.

[0023] See instruction manual attached Figure 1 , Figure 2 and Figure 3 As shown, the pusher conveyor 3 includes two parallel side beams 302. Several base frames 301 are fixedly connected to the bottom sides of the two side beams 302 for support. Two conveyor belts 304 are provided, each positioned on opposite sides of the two side beams 302. Each side beam 302 is equipped with a second motor 303 to drive the conveyor belt 304. The two second motors 303 operate synchronously to drive the two conveyor belts 304 synchronously. Through this specific structural design, under the transmission operation of the conveyor belts 304, when the strip clamping wheel structure 1 rotates the strip to the third station, the protruding strip 305 can push the strip out from under the clamping wheel structure 1 and abut against the strip. This achieves equidistant and uniform distribution of the strips on the conveyor belts 304. By completing the transmission via the conveyor belts 304, the loading and unloading and equidistant distribution of the strips on the strip clamping wheel structure 1 can be achieved, greatly saving process steps and required equipment. The output of the digital display control panel 6 is electrically connected to the input of the second motor 303.

[0024] See instruction manual attached Figure 1 , Figure 3 and Figure 5As shown, the station rotation drive assembly 2 includes a first support frame 204 fixedly mounted on the side beam 302 of the frame. The outer contour of the first support frame 204 is U-shaped. A rotating column 201 is rotatably mounted on the first support frame 204. A fixing sleeve 202 is fixedly mounted on the outer side of the rotating column 201 by bolts. Four rotating rods 203 are evenly distributed around the rotation axis of the rotating column 201 and fixedly connected to the outer side of the fixing sleeve 202. The rotating rods 203 correspond one-to-one with the strip clamping wheel structure 1 and are connected to each other. A first motor 205 is fixedly mounted on the first support frame 204. The output shaft end of the first motor 205 is connected to the rotating shaft end of the rotating column 201 through a grooved wheel mechanism 206. Through the above-described structural design, the output shaft of the first motor 205 can rotate, via the grooved wheel mechanism 206, causing the rotating column 201 to rotate intermittently. Each rotation angle is 90 degrees, thereby realizing the position switching of the strip clamping wheel structure 1 between various workstations. The first and second workstations are both loading workstations, the third workstation is an unloading workstation, and the fourth workstation is an empty workstation. Furthermore, a photoelectric sensor can also be installed at the fourth workstation to determine whether the strip clamping wheel structure 1 has completed unloading at the third workstation. The output terminal of the digital display control panel 6 is electrically connected to the input terminal of the first motor 205.

[0025] See instruction manual attached Figure 5 , Figure 6 and Figure 7 As shown, the strip clamping wheel structure 1 includes two parallel clamping plates 101 connected by a first U-shaped bracket 102. Each clamping plate 101 has an elastic clamping structure on its opposite side for elastically clamping the strip. Each clamping plate 101 is threaded with two or more first adjusting bolts 104. Correspondingly, the first U-shaped bracket 102 has a first adjusting groove 103 through which the first adjusting bolts 104 slide. When the connection between the first adjusting bolts 104 and the first U-shaped bracket 102 is loosened, the clamping plates 101 and the first U-shaped bracket 102 can slide relative to each other, thereby adjusting the distance between the middle rod of the first U-shaped bracket 102 and the elastic clamping structure to accommodate strips of different sizes. Furthermore, the first U-shaped bracket 102 is fixedly connected to a rotating rod 203 to ensure that the strip clamping wheel structure 1 moves synchronously with the rotating rod 203.

[0026] The elastic clamping structure includes a wheel frame 105, on which two or more clamping wheels 106 are rotatably mounted. The clamping wheels 106 directly contact the strip to achieve clamping. Four first guide rods 107 arranged in a rectangular array are fixedly connected to the wheel frame 105. The clamping plate 101 has first guide holes for the first guide rods 107 to slide through, providing guidance for the movement of the wheel frame 105. A rod sleeve 109 is fitted at one end of the first guide rod 107 that passes through the clamping plate 101. A first spring 108 is fitted on the outside of the first guide rod 107 located between the clamping plate 101 and the wheel frame 105. The elastic force of the first spring 108 can make the wheel frame 105 drive the clamping wheels 106 to always tend to move closer to the strip, ensuring the stability of clamping. In addition, when the strip is inserted, the elastic compression deformation of the first spring 108 can make the clamping wheels 106 on the two wheel frames 105 squeeze away from each other.

[0027] The sleeve 109 is threaded with several set bolts 110. A trapezoidal anti-slip groove 111 is formed on the outer side of the end of the first guide rod 107, engaging with the set bolts 110. The trapezoidal anti-slip groove 111 has a right-angled trapezoidal cross-section, with its wide end facing the wheel frame 105. The engagement of the set bolts 110 and the trapezoidal anti-slip groove 111 restricts the sliding range of the first guide rod 107, thereby adjusting the clamping force range of the elastic clamping structure to accommodate strips of different thicknesses.

[0028] See instruction manual attached Figure 4 , Figure 11 , Figure 12 and Figure 13As shown, the first loading assembly 4 includes a first loading box 401 with a rectangular shape and an opening on its upper side. The first loading box 401 is fixedly mounted on the side beam 302 of the frame via a fixing seat 407. Inside the first loading box 401 is a first push block 402 that can slide up and down. The bottom side of the first push block 402 is connected to a first threaded adjusting cylinder 403, which is threadedly connected to a first lead screw 404 connected to the output shaft end of the third motor 405 below the first loading box 401. The bottom side of the fixing seat 407 is fixed by bolts to cover the outside of the first lead screw 404. At the same time, the first loading box 401... 1. A horizontal pushing structure is provided on the upper side to realize the horizontal pushing and feeding of strips. Specifically, the third motor 405 drives the first lead screw 404 to rotate, which drives the first threaded adjusting cylinder 403 and the first push block 402 to move up and down in the first feeding box 401, pushing the strips in the first feeding box 401 upward. This, together with the horizontal pushing structure, completes the horizontal pushing and feeding of the strips. The outer cover cylinder 406 protects the first lead screw 404. In practical applications, a distance sensor can be set above the first feeding box 401 to detect the height of the uppermost strip, thereby realizing feedback control of the third motor 405. The output terminal of the digital display control panel 6 is electrically connected to the input terminal of the third motor 405.

[0029] The horizontal pushing structure consists of a support slide 411 located on one side of the upper part of the first feeding box 401, two first cylinders 409, and a pusher plate 410. The support slide 411 has an opening slot 412 on the side facing the center of the station rotation drive assembly 2, through which the strip clamping wheel structure 1 passes, providing a channel and support for the horizontal pushing of the strip. The two first cylinders 409 are fixed to the first feeding box 401 via brackets 408, and their push rod heads are respectively fixedly connected to the pusher plate 410. A hanging strip 413 protrudes from the lower side of the pusher plate 410 away from the station rotation drive assembly 2. Through this specific structural design, the horizontal pushing structure drives the pusher plate 410 through the first cylinders 409, and the hanging strip 413 can horizontally push the strip pushed to the top of the first feeding box 401 along the support slide 411, ultimately feeding it into the strip clamping wheel structure 1, thus realizing the feeding of the strip. The output of the digital display control panel 6 is electrically connected to the input of the first cylinder 409.

[0030] See instruction manual attached Figure 3 , Figure 8 , Figure 9 and Figure 10As shown, the second plate loading assembly 5 includes a second support frame 502, which is fixedly mounted on the side beam 302 of the frame. A fixing rod 520 is fixedly connected between the first support frame 204 and the second support frame 502. The second loading box 501 is fixed on the fixing rod 520. The second loading box 501 is U-shaped with an opening at the top. A second push block 506 is slidably disposed inside the second loading box 501. A second threaded adjusting cylinder 505 is fixedly connected to one side of the second push block 506. A fourth motor 503 is fixed on 502. The output shaft of the fourth motor 503 is connected to one end of the second lead screw 504. The other end of the second lead screw 504 is threaded into the second threaded adjusting cylinder 505. The two side walls of the second feeding box 501 are provided with first guide grooves 510. The two ends of the second push block 506 are fixed with guide slide columns 511 that cooperate with the first guide grooves 510 to guide and slide. The second feeding box 501 is provided with a vertical push structure for vertically pushing the strip from the second feeding box 501. Through the above specific structural design, the rotation of the output shaft of the fourth motor 503 can drive the second lead screw 504 to rotate. The rotation of the second lead screw 504 drives the second threaded adjusting cylinder 505 and the second push block 506 to move within the second feeding box 501. The guide slide column 511 and the first guide slide groove 510 cooperate to guide and limit the movement of the second push block 506 within the second feeding box 501. The output end of the digital display control panel 6 is electrically connected to the input end of the fourth motor 503.

[0031] The vertical push structure consists of a second U-shaped bracket 507, a second cylinder 508, an L-shaped push plate 509, a stop wheel 513, a wheel rod 512, and other components fixed on the second feeding box 501. The second cylinder 508 is fixedly mounted on the second U-shaped bracket 507. The push rod head of the second cylinder 508 faces downward and is connected to an L-shaped push plate 509. The discharge port of the second feeding box 501 is provided with two or more abutment rollers 513. Each abutment roller 513 has a wheel rod 512 at both ends. Two or more second adjusting bolts 516 threaded on both sides of the second feeding box 501 pass through the second adjusting groove 515 on the wheel rod 512. Loosening the second adjusting bolts 516 can adjust the distance between the abutment roller 513 and the second feeding box 501. After adjustment, the second adjusting bolts 516 can be tightened again. A guide slider 518 is slidably provided in the second guide groove 517 on the wheel rod 512. The two ends of the abutment roller 513 are rotatably located between the two guide sliders 518. The second guide rod 519 connected to the guide slider 518 slides into the second guide sliding hole of the wheel rod 512, and a second spring 514 is sleeved on the outside of the second guide rod 519. The entire assembly is driven downwards by the second cylinder 508, which pushes the L-shaped pusher 509 vertically out of the second loading box 501. The abutment roller 513, under the action of the second spring 514, provides elastic support to the strip, ensuring stability during the pushing process. The adjustable structure can accommodate the pushing requirements of strips of different sizes. The abutment roller 513 also reduces friction between its contact surface and the strip, facilitating the downward movement of the strip. The output of the digital display control panel 6 is electrically connected to the input of the second cylinder 508.

[0032] Working principle and technical effects of the present invention: In use, the first motor 205 of the station rotation drive assembly 2 can drive the rotating column 201 to rotate under the support of the first support frame 204. The grooved wheel mechanism 206 is set between the first motor 205 and the rotating column 201, which can realize the intermittent transmission of the rotating column 201. This allows the strip clamping wheel structure 1 to stop precisely when it rotates to a preset station, such as the first station, the second station, or the third station. When it moves to the first station, the first strip loading assembly 4 pushes out the strip at the top of the first loading box 401. The strip is supported and slid by the support slide 411, thereby pushing the strip into the clamping wheel 106 of the strip clamping wheel structure 1 for clamping. The middle rod of the first U-shaped bracket 102 can play a limiting role when the strip is loaded. According to the different sizes of the strip, the position between the clamping plate 101 and the first U-shaped bracket 102 can be adjusted by tightening or loosening the first adjusting bolt 104, thereby adapting to different sizes of the strip. The first and second strip loading components 4 and 5 serve as the main and auxiliary loading positions, respectively. The first strip loading component 4 loads the strip clamping wheel structure 1. A photoelectric sensor 7 can be installed on the first support frame 204 to detect whether the loading of the strip clamping wheel structure 1 is complete. The output of the photoelectric sensor 7 is electrically connected to the input of the digital display control panel 6. When it is detected that the strip clamping wheel structure 1 is not clamping a strip, the second strip loading component 5 loads the strip clamping wheel structure 1. In addition, when the strips in the first loading box 401 of the first strip loading component 4 are used up and strips need to be refilled in the first loading box 401, the second strip loading component 5 can load the strip clamping wheel structure 1 to ensure uninterrupted and continuous loading.

[0033] When the workstation rotation drive assembly 2 drives the strip clamping wheel structure 1 to move the strip to the third workstation, the conveyor belt 304 of the pusher conveyor 3 rotates, which can drive the outer side of the conveyor belt 304 to push the strip with the protruding strip 305, thereby realizing the strip detaching from the strip clamping wheel structure 1, and also realizing the equidistant transmission of the strip for coating.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
