Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to an LED lighting manufacturing production line and its usage method. Background Technology

[0002] When manufacturing strip-shaped LED lights, it is necessary to process them into shapes such as... Figure 6 The positioning base (usually a carrier box, also called a lamp holder) of the lamp 004 shown is fixed to the conveying equipment by a clamp. Then, the conveying equipment carries the positioning base of the lamp through multiple stations in sequence for assembly (installing LED light source board, LED driver circuit and lamp cover on the lamp holder), gluing, testing and other processes, and finally completes the processing and production of the LED lamp.

[0003] Chinese invention patent application number 202310193318.5 discloses a conveying device for assembling LED lamp tubes. It uses a pressure sensor to determine whether the lamp holder is placed on a fixed component, uses an inflatable component in conjunction with an airbag to squeeze the lamp holder to achieve clamping and positioning of the lamp holder, and uses a conveying chain to drive the fixed lamp holder to move. The whole device has strong applicability, good conveying stability, and causes less damage to the lamps during use.

[0004] However, in order to achieve the function of clamping and fixing the lamp holder, the above solution requires a large number of sensors, gas pipelines and corresponding valves. The entire device has a complex structure, high cost, high failure rate and inconvenient maintenance, which is not conducive to on-site production.

[0005] Therefore, there is a need for an LED lighting production line that is relatively simple in structure, low in cost, not prone to failure, highly applicable, stable, and causes minimal damage to the lighting fixtures during positioning. Summary of the Invention

[0006] This application provides an LED lighting fixture processing production line, which solves the technical problems of complex structure, high cost, high failure rate and inconvenient maintenance of positioning and conveying components in the existing lighting fixture production process. It achieves the technical effect of relatively simple structure, low cost, less prone to failure, strong applicability, good stability and less damage to the lighting fixtures when positioning them.

[0007] This application provides an LED lighting manufacturing production line, including a conveying assembly and side workstations disposed on one or both sides of the conveying assembly;

[0008] The conveying assembly includes a basic conveying assembly and side positioning assemblies positioned on both sides of the basic conveying assembly, both of which are horizontally oriented conveyor belt structures.

[0009] A row of limiting bodies is positioned at equal intervals on the outer ring of the annular belt of the basic conveying component and the outer ring of the rotating belt of the side positioning component;

[0010] The limiting body on the basic conveying assembly is a compression positioning strip, and the limiting body on the side positioning assembly is an abutment positioning body; the abutment positioning body can be a block, column, or rod.

[0011] The extrusion positioning strip is hollow inside, with a built-in soft bladder and pressure plate inside, and a side passage groove on one side.

[0012] A magnetic attraction plate is positioned within the space enclosed by the annular belt; the attraction plate is arranged laterally and is positioned near one end of the basic conveying assembly.

[0013] When in use, adjust the gap between the contact positioning body and the extrusion positioning strip according to the specifications of the lamp to be positioned. Place the positioning base of the lamp in the gap between the two. Under the influence of the magnetic force of the attraction plate, the pressure plate will squeeze the built-in soft bladder so that it protrudes from the side groove, and then cooperate with the two adjacent contact positioning bodies to squeeze and bind the positioning base of the lamp.

[0014] Furthermore, the length of the side positioning component is shorter than or equal to the length of the basic conveying component, and the length direction is the same as the length direction of the basic conveying component.

[0015] Preferably, it also includes a bottom guide rail;

[0016] The bottom guide rail is a rigid guide rail placed horizontally on the ground, with its length direction being the same as the width direction of the basic conveying component; the side positioning component is slidably positioned on the bottom guide rail and is controlled to slide along the bottom guide rail.

[0017] Preferably, it also includes a side pressure body, splicing plates, and a telescopic frame;

[0018] The suction plate is provided with two combined through slots;

[0019] The combined through-slot is a long rectangular slot, with its length direction being the same as the width direction of the suction plate;

[0020] The splicing plate is a strip-shaped rectangular rigid plate with magnetic force, and its edge contour matches the combined through groove.

[0021] The telescopic frame is used to support and position the splicing panel. It is a vertical telescopic rod that can extend and retract in a controlled manner.

[0022] The side pressure body is a horizontally placed rigid telescopic rod that extends and retracts in a controlled manner. It is located on both sides of the conveying assembly and is positioned on the ground by a bracket.

[0023] Preferably, it also includes an end positioning component;

[0024] The number of the end positioning components is two, located on both sides of the conveying component, and their own length direction is the same as that of the conveying component. They are slidably positioned on the bottom guide rail and slide along the bottom guide rail in a controlled manner, including a sliding frame, a rotating wheel and a pressure soft ring.

[0025] The sliding frame is a rigid frame that is positioned on the bottom guide rail;

[0026] An end positioning assembly includes two rotating wheels and a pressure-applying soft ring. Both rotating wheels are vertically arranged and positioned on the sliding frame.

[0027] The pressure-applying soft ring is a rubber ring that is stretched into an elongated shape by being fitted onto two rotating wheels. It is always in a taut state, and the height of its top surface is similar to the height of the top surface of the compression positioning strip.

[0028] Preferably, it also includes a continuing processing component;

[0029] The structure of the continuing processing component is the same as that of the conveying component, and the length direction is also the same as that of the conveying component. Both are arranged laterally, and part of the continuing processing component is located directly below the conveying component.

[0030] The support column near the continuing processing component is provided with an annular groove for accommodating the suction plate;

[0031] The longitudinal section of the suction plate on the conveying assembly is U-shaped;

[0032] The support column at the far end of the conveyor assembly is coaxial with and has the same diameter as the two end wheels at the far end of the conveyor assembly;

[0033] When in use, after the top surface of the lamp is processed by the conveying component, it will rotate to the bottom surface of the conveying component. After moving away from the attraction plate, it will fall down under the combined influence of its own weight and magnetic force and be upside down onto the continuing processing component.

[0034] Preferably, the top surface of the extrusion positioning strip has a through hole at its center, with the axial direction being the same as the height direction of the extrusion positioning strip;

[0035] The extrusion positioning strip also has a through shaft, a top plate, and an elastic sleeve positioned on it.

[0036] The through shaft passes through the through hole in the extrusion positioning strip and one end is fixed to the outer ring of the annular belt;

[0037] The top plate is a rigid plate and is fixed to the other end of the through shaft;

[0038] The elastic sleeve is an annular rubber sleeve that is fitted onto the through shaft. Its top and bottom surfaces abut against the top plate and the extrusion positioning strip, respectively, and it is always in a compressed state.

[0039] The contact positioning body of the side positioning component is rod-shaped;

[0040] In use, the extrusion positioning strips are rotated one by one at a certain angle, and the positioning components on both sides are controlled to run at different speeds, so that the lamps to be processed can be positioned horizontally and at an angle on the conveying components.

[0041] Preferably, it also includes an angle adjustment component;

[0042] Both ends of the extrusion positioning strip are positioned with an end attraction block;

[0043] A bottom support plate is fixed to the end of the through shaft on the extrusion positioning strip that is away from the top plate; the bottom support plate is a rigid circular plate that is tightly attached to and fixed to the annular belt.

[0044] A top matching plate is fixed on the surface of the extrusion positioning strip near the bottom support plate;

[0045] The top matching plate is sleeved on the through shaft; the bottom support plate and the top matching plate are normally in close contact, and the surfaces of the two in close contact are provided with multiple interlocking teeth;

[0046] The angle adjustment component uses magnetic force to drive the compression positioning strip upward and rotate it to the required angle.

[0047] Preferably, the extrusion positioning strip is a hollow cylinder with a built-in soft bladder and a pressure plate, and a side passage groove on the side wall; in use, the built-in soft bladder protrudes to extrude and position the lamp.

[0048] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0049] By optimizing and improving the structure of existing LED lighting production lines, three parallel conveyor belt assemblies are used to jointly carry and transport the lighting fixtures. A row of limiting bodies is installed on the outer ring of the annular belt of each of the three conveyor belt assemblies. Before transporting the lighting fixtures, the three conveyor belt assemblies are controlled to operate asynchronously, creating gaps between the limiting bodies for the lighting fixtures to be placed. An airbag is installed on the limiting body of the middle conveyor belt assembly. During the transport of the lighting fixtures, magnetic force is used to indirectly control the deformation of the airbag, causing it to press against and compress the lighting fixtures, thus securing them. Workers and / or machinery perform assembly and other operations on one or both sides of the three conveyor belt assemblies. This effectively solves the technical problems of complex structures, high costs, high failure rates, and inconvenient maintenance of positioning and conveying components in existing lighting production processes. This results in a relatively simple structure, low cost, low failure rate, strong applicability, good stability, and minimal damage to the lighting fixtures during positioning.

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0068] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0069] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0070] Example 1

[0071] like Figures 1 to 5 As shown, the LED lighting production line of this application includes a conveying assembly 001, a side station 003, a power assembly, and a control unit.

[0072] The conveying assembly 001 is used to carry, position, and convey the lamps 004; the side workstations 003 are multiple workstations set on one or both sides of the conveying assembly, where workers and / or mechanical equipment perform assemblies, gluing, testing, and other operations on the lamps 004 on the conveying assembly 001.

[0073] The conveying assembly 001 includes a basic conveying assembly 100 and side positioning assemblies 200 positioned on both sides of the basic conveying assembly 100;

[0074] The main bodies of the basic conveying assembly 100 and the side positioning assembly 200 are both horizontally oriented conveyor belt structures.

[0075] The basic conveying assembly 100 includes a carrier frame 110, a support column 120, an annular belt 130, and also includes an extrusion positioning strip 140 and a support carrier 150.

[0076] The carrier frame 110 is a rigid frame that is positioned on the ground and is used to support the support column 120.

[0077] The support column 120 is a horizontally placed cylindrical wheel, and there are two of them. The two support columns 120 have the same axis, and at least one of them rotates under the coordinated control of the control unit and the power component, and is used to support and position the annular belt 130.

[0078] The annular belt 130 is an annular belt that is fitted onto the two support belt columns 120. It is stretched into an elongated shape by the two support belt columns 120 and is always in a taut state. It rotates under the drive of the support belt columns 120.

[0079] The compression positioning strips 140 are used to limit the position of the lamp 004 on the annular belt 130 and controllably clamp and fix the lamp 004. They are arranged in a row on the annular belt 130, with their length direction being the same as the width direction of the annular belt 130, and the spacing between them being equal and greater than 8 cm. The compression positioning strips 140 are generally straight strips with a hollow interior. They contain an internal soft bladder 142 and a pressure plate 143, and have a side groove 141 on one side. The side groove 141 is arranged horizontally to allow the internal soft bladder 142 to protrude from the compression positioning strip 140 when subjected to greater pressure. The internal soft bladder 142 is a long strip of elastic rubber bladder that normally occupies more than two-thirds of the internal space of the compression positioning strip 140. The pressure plate 143 is a horizontally placed iron plate fixed to the top of the internal soft bladder 142. Under the influence of magnetic force, it will apply pressure to the internal soft bladder 142 from the top, causing part of the internal soft bladder 142 to protrude from the side groove 141.

[0080] The support carrier 150 is a horizontally placed rigid plate, positioned within the space enclosed by the annular belt 130. Its top surface abuts against the inner ring of the annular belt 130, supporting the annular belt 130 to prevent it from sagging and affecting the positioning of the lamp 004. It is positioned on the ground by a rigid bracket. The support carrier 150 has an attraction plate 152 and a positioning groove 151 for accommodating the attraction plate 152. The positioning groove 151 is located at the top of the support carrier 150. The attraction plate 152 is a horizontally placed rigid plate with magnetic force, preferably a permanent magnet, positioned within the positioning groove 151, and its top surface is coplanar with the top surface of the support carrier 150. The length of the attraction plate 152 is more than half the length of the support carrier 150, and its width is more than half the width of the support carrier 150. Its length direction is the same as the length direction of the support carrier 150, and it is located near one end of the support carrier 150.

[0081] The side positioning component 200 is used to cooperate with the basic conveying component 100 to complete the positioning of the lamp 004. There are two of them, located on both sides of the basic conveying component 100 respectively. The length is shorter than or equal to the length of the basic conveying component 100, and the length direction is the same as the length direction of the basic conveying component 100.

[0082] The two positioning components 200 operate synchronously, have the same structure, and are symmetrically arranged.

[0083] The side positioning component 200 includes a positioning frame 210, an end wheel 220, a rotating belt 230, and an abutment positioning body 240;

[0084] The positioning frame 210 is a rigid support that is positioned on the ground and serves to support the end wheel 220.

[0085] The end wheel 220 is a horizontally placed rigid cylindrical wheel body, which has the same axial direction and diameter as the support column 120, and at least one of them rotates under the coordinated control of the control unit and the power component; a side positioning component 200 includes two end wheels 220 and a rotating belt 230;

[0086] The rotating belt 230 is a ring-shaped belt that is fitted onto two end wheels 220. It is stretched into an elongated shape by the two end wheels 220 and is always taut. It rotates under the drive of the end wheels 220.

[0087] The contact positioning body 240 is used to cooperate with the compression positioning strip 140 to clamp and position lamps 004 of different specifications;

[0088] A row of contact positioning bodies 240 are evenly spaced on the outer ring of the rotating belt 230; the contact positioning bodies 240 are blocks, columns or rods (if they are columns or rods, one end is fixed to the rotating belt 230), and the distance between them is greater than 8 cm.

[0089] In use, a compression positioning strip 140 of the basic conveying component 100, together with two abutting positioning bodies 240 on the two side positioning components 200, clamps and positions a lamp 004.

[0090] To prevent the rotating belt 230 from sagging under its own weight and affecting its use, the side positioning assembly 200 further includes a carrier strip 250 and a carrier frame 260 for supporting the carrier strip 250. The carrier strip 250 is a horizontally placed rigid plate or rod, positioned in the space enclosed by the rotating belt 230, with its top surface abutting against the inner ring of the rotating belt 230, and positioned on the ground by the carrier frame 260. The carrier frame 260 is a rigid frame.

[0091] The power assembly is used to provide power for the operation of various components of the LED lighting production line of this application, and the control unit plays the role of controlling the coordinated operation of various components of the LED lighting production line. Both are existing technologies and will not be described in detail here.

[0092] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0093] For ease of description, the two ends of the conveying component 001 are defined as the near end and the far end, respectively. In use, the positioning base of the lamp is placed on the production line at the near end, and the finished lamp 004 is output at the far end. The attraction plate 152 is set close to the far end.

[0094] The steps for processing LED lamps using the LED lamp processing production line of this application are as follows:

[0095] 1. First, according to the specifications of the lamp 004 to be processed, control the asynchronous movement of the annular belt 130 and the rotating belt 230 so that the gap between the extrusion positioning strip 140 and the adjacent abutting positioning body 240 can be used to place the positioning base of the lamp to be processed.

[0096] 2. Using manual or mechanical equipment, place the positioning bases of the lamps one by one into the gap between the extrusion positioning strip 140 and the contact positioning body 240, and use manual or mechanical equipment (preferably a robotic arm) to apply pressure and push force from the end of the positioning base of the lamps so that the end is flush with the edge of one of the side positioning components 200 away from the base conveying component 100; at the same time, control the base conveying component 100 and the side positioning component 200 to run at a uniform speed and intermittently.

[0097] 3. During the operation of the basic conveying assembly 100 and the side positioning assembly 200, the positioning base of the lamp will gradually approach the top of the attraction plate 152; when the positioning base of the lamp moves to the top of the attraction plate 152, the pressure plate 143 will press down the built-in soft bag 142 under the influence of magnetic force, causing it to bulge out from the side through groove 141 and squeeze the positioning base of the lamp, so that the positioning base of the lamp is tightly attached to the abutting positioning body 240 on the side positioning assembly 200, thereby fixing the positioning base of the lamp.

[0098] 4. During the operation of the basic conveying component 100 and the side positioning component 200, the workers and / or mechanical equipment in the side station 003 perform assemblies, glue application, testing and other operations on the positioning base of the lamps carried by the conveying component 001 in the side station 003 so that they gradually become finished lamps.

[0099] 5. The finished lamp will be released from the fixed position when its corresponding extrusion positioning strip 140 moves away from the suction plate 152, and then output from the conveying assembly 001.

[0100] Preferably, to further enhance the applicability of this application and enable it to adapt to more specifications of lighting fixtures 004, the LED lighting fixture processing production line of this application also includes a bottom guide rail 300; such as Figure 3 As shown, the bottom guide rail 300 is a rigid guide rail placed horizontally on the ground, and its length direction is the same as the width direction of the basic conveying component 100; the side positioning component 200 is slidably positioned on the bottom guide rail 300, and slides along the bottom guide rail 300 under the coordinated control of the control unit and the power component, so that the distance between the side positioning component 200 and the basic conveying component 100 can be adjusted as needed.

[0101] Furthermore, both the positioning frame 210 and the carrier frame 260 are slidably positioned on the bottom guide rail 300.

[0102] Considering that when assembling lamp 004 using the production line of this application, some components of lamp 004 (such as buttons) need to be installed on the side of the lamp's positioning base, the installation position may be covered when the positioning base of the lamp is clamped by the extrusion positioning strip 140 and the abutting positioning body 240, which hinders the production operation; preferably, as Figure 1As shown, the LED lighting fixture processing and production of this application also includes a side pressure body 400; the attraction plate 152 is provided with two combined through slots 154; the combined through slot 154 is a long rectangular slot, the length direction is the same as the width direction of the attraction plate 152, and the width is greater than four-fifths of the width of the attraction plate 152; the top of the support carrier 150 is provided with a receiving slot 153 near the combined through slot 154; the receiving slot 153 is located directly below the combined through slot 154 and is used to receive the splicing plate 155 and the telescopic frame 156; the splicing plate 155 is a strip-shaped rectangular rigid plate with magnetic force, preferably a permanent magnet, and its edge contour matches the combined through slot 154. After being inserted into the combined through slot 154, it will seal the combined through slot 154; the telescopic frame 156 is used to support and position the splicing plate 155 and is vertically oriented. The telescopic rod, with its bottom positioned within the receiving groove 153 and its top positioned at the bottom of the splicing plate 155, is controlled to extend and retract, thereby changing the height of the splicing plate 155. The side pressure body 400 is a horizontally placed rigid telescopic rod, controlled to extend and retract, located on both sides of the conveying assembly 001, and positioned on the ground by a bracket. The two side pressure bodies 400 are respectively set close to the two combined through grooves 154. If the mounting position of the component on the side of the positioning base of the lamp on the production line is blocked, the splicing plate 155 can be controlled to move downward, so that the magnetic influence of the extrusion positioning strip 140 is reduced when it moves directly above the splicing plate 155, thereby reducing the clamping force on the positioning base of the lamp when it is close to the combined through groove 154. At this time, controlling the extension of the side pressure body 400 can push the positioning base of the lamp to move laterally to expose the mounting position for assembly operations.

[0103] Considering that during installation, a significant lateral force may be applied to the positioning base of the lamp during the installation process, potentially causing the positioning base to shift laterally along its length. This could alter the positional relationship between the positioning base and the conveying assembly 001, affecting subsequent operations; preferably, as... Figure 1As shown, it also includes end positioning components; there are two end positioning components, located on both sides of the conveying component 001, with their length direction being the same as that of the conveying component 001. They are slidably positioned on the bottom guide rail 300 and slide controlled along the bottom guide rail 300, including a sliding frame 510, rotating wheels 520, and a pressure soft ring 530; the sliding frame 510 is a rigid frame, positioned on the bottom guide rail 300, and serves to support the rotating wheels 520; one end positioning component includes two rotating wheels 520 and one pressure soft ring 530, the two rotating wheels 520 are set at the same height, both are vertically positioned and fixed. Located on the sliding frame 510, at least one of them is controlled to rotate; the pressure soft ring 530 is a rubber ring, which is wrapped around the two rotating wheels 520 and stretched into an elongated shape, always in a taut state, and the height of its top surface is similar to the height of the top surface of the extrusion positioning strip 140 (the height difference does not exceed 5 mm); if the lamp 004 (including the positioning base of the lamp) requires a large force along its length to be applied to it in some processes on the production line, the two end positioning components and the base conveying component 100 can be controlled to run synchronously and then move laterally to abut and bind the two ends of the lamp 004, so as to prevent the lamp 004 from shifting along its own length due to the force.

[0104] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0105] This invention solves the technical problems of complex structure, high cost, high failure rate and inconvenient maintenance of positioning and conveying components in the existing lamp manufacturing process. It achieves the technical effect of relatively simple structure, low cost, less prone to failure, strong applicability, good stability and less damage to lamps when positioning them.

[0106] Example 2

[0107] Considering that some lamps 004 require assembly components (such as mounting clips) on their back side (the side away from the lampshade) during processing, and because the bottom of the lamp 004 needs to be placed on the annular belt 130 and the rotating belt 230 on the production line, assembly is difficult; to further improve the applicability and practicality of the LED lamp processing production line of this application, this embodiment adds a continuing processing component 002 based on the above embodiment, and optimizes and improves the structure of the suction plate 152. The continuing processing component 002 supports the lamp 004 from the conveying component 001 and performs operations such as installing components on its back side, specifically:

[0108] like Figures 7 to 9 As shown, the structure of the continuing processing component 002 is the same as that of the conveying component 001, and the length direction is also the same as that of the conveying component 001. Both are arranged horizontally, and part of the continuing processing component 002 is located directly below the conveying component 001.

[0109] The proximal end of the continuing processing component 002 is close to the distal end of the conveying component 001;

[0110] An annular groove for accommodating the suction plate 152 is provided on the support column 120 near the continuing processing component 002;

[0111] The longitudinal section of the suction plate 152 on the conveying assembly 001 is U-shaped and is a curved plate that wraps around the support column 120 with an annular groove, with the opening facing the near end of the conveying assembly 001.

[0112] The support column 120 at the far end of the conveyor assembly 001 is coaxial with the two end wheels 220 at the far end of the conveyor assembly 001 and has the same diameter;

[0113] When in use, after the top surface of the lamp 004 is processed by the conveying component 001, it will rotate to the bottom surface of the conveying component 001. After moving away from the attraction plate 152, it will fall down under the combined influence of its own weight and magnetic force and be upside down on the continuing processing component 002. Then it will be transported away by the continuing processing component 002 for further processing.

[0114] Example 3

[0115] To further improve the practicality and applicability of this application, and to reduce production line space, lower equipment costs, reduce energy consumption, and improve operational efficiency while ensuring applicability, this application optimizes and improves the structure of the extrusion positioning strip 140 based on the above embodiments. This allows the robotic arm in side station 003, used for assembling parts, to have a smaller working range to meet the usage requirements (a robotic arm with a smaller working range consumes less energy and has higher operational efficiency). Specifically:

[0116] like Figures 10 to 12 As shown, the top surface of the extrusion positioning strip 140 has a through hole at its center, with the axial direction being the same as the height direction of the extrusion positioning strip 140.

[0117] The extrusion positioning strip 140 is also positioned with a through shaft 144, a top plate 145 and an elastic sleeve 146.

[0118] The through shaft 144 is a rigid shaft with a length greater than 1.3 times the height of the extrusion positioning strip 140. It passes through the through hole on the extrusion positioning strip 140 and one end is fixed to the outer ring of the annular belt 130.

[0119] The top plate 145 is a rigid plate, preferably a circular plate, with its thickness direction being the same as the axial direction of the through shaft 144 and fixed to the end of the through shaft 144 away from the annular belt 130.

[0120] The elastic sleeve 146 is an annular rubber sleeve that is fitted on the through shaft 144. Its top and bottom surfaces abut against the top plate 145 and the compression positioning strip 140, respectively, and it is always in a compressed state.

[0121] The abutment positioning body 240 of the side positioning component 200 is in the shape of a round rod.

[0122] In use, the extrusion positioning strips 140 can be rotated one by one at a certain angle manually or by a robotic arm, and the positioning components 200 on both sides can be controlled to run at different speeds (which causes the abutting positioning bodies 240 on the positioning components 200 on both sides to be misaligned). This allows the lamps 004 to be processed to be positioned horizontally and at an angle on the conveying component 001, thereby saving space, reducing equipment costs, reducing energy consumption, and improving work efficiency.

[0123] Example 4

[0124] To further improve the practicality and applicability of this application and enhance the ease of use in the production line, the embodiments of this application optimize and improve the structure of the extrusion positioning strip 140 based on the above embodiments, and add an angle adjustment component for efficiently and automatically adjusting the angle of the extrusion positioning strip 140, specifically:

[0125] like Figures 13 to 15 As shown, each end of the extrusion positioning strip 140 is positioned with an end attraction block 147; the end attraction block 147 is a plate or block made of ferromagnetic material.

[0126] A bottom support plate 650 is fixed to the end of the through shaft 144 on the extrusion positioning strip 140 away from the top plate 145; the bottom support plate 650 is a rigid round plate that is tightly attached to and fixed to the annular belt 130.

[0127] A top matching plate 660 is fixed on the surface of the extrusion positioning strip 140 near the bottom support plate 650; the top matching plate 660 is sleeved on the through shaft 144; the bottom support plate 650 and the top matching plate 660 are normally in close contact, and the surfaces in close contact are provided with a plurality of interlocking teeth, which are used to limit the relative rotation of the two.

[0128] The angle adjustment assembly includes a support body 610, a rotating telescopic body 620, a bottom shaped frame 630, and an end suction body 640.

[0129] The support body 610 is a rigid frame, preferably L-shaped, used to support the rotating telescopic body 620;

[0130] The rotating telescopic body 620 is positioned directly above the basic conveying assembly 100 via the bracket body 610. It is a rigid telescopic rod that is vertically set and can be controlled to rotate and extend around its own axis.

[0131] The bottom C-shaped frame 630 is a C-shaped rigid frame with its opening facing downwards and its top fixed to the bottom of the rotating telescopic body 620;

[0132] The end adsorption body 640 is a permanent magnet or an electromagnet block, and there are two of them, which are positioned at or near the two ends of the bottom bracket 630.

[0133] If there is a need to rotate the extrusion positioning strip 140, the end adsorption body 640 can be controlled to approach both ends of the extrusion positioning strip 140. The magnetic force, combined with the contraction of the rotating telescopic body 620, controls the extrusion positioning strip 140 to move upward, overcoming the elastic force of the elastic sleeve 146 so that the bottom support plate 650 is separated from the top matching plate 660. Then, the extrusion positioning strip 140 is rotated as needed by rotating the bottom mortise frame 630.

[0134] Example 5

[0135] To improve the ease of use of the production line of this application, the structure of the extrusion positioning strip 140 has been optimized and improved based on the above embodiments, specifically as follows:

[0136] The extrusion positioning strip 140 is a hollow cylinder with an internal soft pouch 142 and a pressure plate 143 inside, and a side through groove 141 on the side wall. When in use, the internal soft pouch 142 protrudes to extrude and position the lamp 004. When the lamp 004 needs to be transported at an angle, there is no need to adjust the angle. However, due to the limitations of the structure of the extrusion positioning strip 140, the clamping force on the lamp 004 will be relatively small, and the stability of the fixation will be relatively poor.

[0137] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
